CENTERPOINT ENERGY, INC. AND SUBSIDIARIES NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (1) BACKGROUND AND BASIS OF PRESENTATION Included in this Quarterly Report on Form 10-Q (Form 10-Q) of CenterPoint Energy, Inc. (CenterPoint Energy), together with its subsidiaries (collectively, the Company), are CenterPoint Energy's consolidated interim financial statements and notes (Interim Financial Statements) including these companies' wholly owned and majority owned subsidiaries. The Company has filed a Current Report on Form 8-K dated May 12, 2003 (May 12 Form 8-K). The May 12 Form 8-K gives effect to certain reclassifications that have been made to the Company's historical financial statements as presented in the Annual Report on Form 10-K of CenterPoint Energy (CenterPoint Energy Form 10-K) for the year ended December 31, 2002. The Interim Financial Statements are unaudited, omit certain financial statement disclosures and should be read with the May 12 Form 8-K. RESTRUCTURING CenterPoint Energy is a public utility holding company, created on August 31, 2002 as part of a corporate restructuring of Reliant Energy, Incorporated (Reliant Energy) that implemented certain requirements of the Texas electric restructuring law described below. In December 2000, Reliant Energy transferred a significant portion of its unregulated businesses to Reliant Resources, Inc. (Reliant Resources), which, at the time, was a wholly owned subsidiary of Reliant Energy. Reliant Resources conducted an initial public offering of approximately 20% of its common stock in May 2001 (the Reliant Resources Offering). In December 2001, Reliant Energy's shareholders approved an agreement and plan of merger pursuant to which the following steps occurred on August 31, 2002 (the Restructuring): o CenterPoint Energy became the holding company for the Reliant Energy group of companies; o Reliant Energy and its subsidiaries became subsidiaries of CenterPoint Energy; and o each share of Reliant Energy common stock was converted into one share of CenterPoint Energy common stock. On September 5, 2002, CenterPoint Energy announced that its board of directors had declared a distribution of all of the shares of Reliant Resources common stock owned by CenterPoint Energy to its common shareholders on a pro rata basis (the Reliant Resources Distribution). The Reliant Resources Distribution was made on September 30, 2002. CenterPoint Energy is the successor to Reliant Energy for financial reporting purposes under the Securities Exchange Act of 1934. The Company's operating subsidiaries own and operate electric transmission and distribution facilities, natural gas distribution facilities, natural gas pipelines and electric generating plants. The Company is subject to regulation as a "registered holding company" under the Public Utility Holding Company Act of 1935 (1935 Act). As of March 31, 2003, the Company's indirect wholly owned subsidiaries include: o CenterPoint Energy Houston Electric, LLC (CenterPoint Houston), which engages in Reliant Energy's former electric transmission and distribution business in a 5,000-square mile area of the Texas Gulf Coast that includes Houston; and o CenterPoint Energy Resources Corp. (CERC Corp., and, together with its subsidiaries, CERC), formerly Reliant Energy Resources Corp. (RERC Corp., and, together with its subsidiaries, RERC), which owns gas distribution systems that together form one of the United States' largest natural gas distribution operations in terms of number of customers served. Through wholly owned subsidiaries, CERC owns two interstate natural gas pipelines and gas gathering systems and provides various ancillary services. The Company also has an approximately 81% ownership interest in Texas Genco Holdings, Inc. (Texas Genco), which owns and operates the Texas generating plants formerly belonging to the integrated electric utility that was a part of Reliant Energy. The Company distributed approximately 19% of the 80 million outstanding shares of common stock of Texas Genco to the Company's shareholders on January 6, 2003. As a result of the distribution of 5

Texas Genco common stock, CenterPoint Energy recorded an impairment charge of $396 million, which is reflected as a regulatory asset representing stranded costs in the Consolidated Balance Sheets as of March 31, 2003. This impairment charge represents the excess of the carrying value of CenterPoint Energy's net investment in Texas Genco over the market value of the Texas Genco common stock that was distributed. The financial impact of this impairment was offset by recording a $396 million regulatory asset reflecting the Company's expectation of stranded cost recovery of such impairment. See Note 4(c) for a discussion of generation related regulatory assets. Additionally, in connection with the distribution, CenterPoint Energy recorded minority interest ownership in Texas Genco of $146 million in its Consolidated Balance Sheets in the first quarter of 2003. BASIS OF PRESENTATION The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Interim Financial Statements reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position and results of operations for the respective periods. Amounts reported in the Company's Statements of Consolidated Income are not necessarily indicative of amounts expected for a full year period due to the effects of, among other things, (a) seasonal fluctuations in demand for energy and energy services, (b) changes in energy commodity prices, (c) timing of maintenance and other expenditures and (d) acquisitions and dispositions of businesses, assets and other interests. In addition, certain amounts from the prior year have been reclassified to conform to the Company's presentation of financial statements in the current year. These reclassifications do not affect net income. Subsequent to December 31, 2002, the Company sold all of its remaining Latin America operations. The Interim Financial Statements present these remaining Latin America operations as discontinued operations in accordance with Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS No. 144). Accordingly, the Interim Financial Statements reflect these operations as discontinued operations for the three months ended March 31, 2002 and 2003. The Interim Financial Statements have been prepared to reflect the effects of the Restructuring and the Reliant Resources Distribution as described above on the CenterPoint Energy financial statements. The Interim Financial Statements present the Reliant Resources businesses (previously reported as the Wholesale Energy, European Energy, and Retail Energy business segments and related corporate costs) as discontinued operations, in accordance with SFAS No. 144. Accordingly, the Interim Financial Statements reflect these operations as discontinued operations for the three months ended March 31, 2002. The following notes to the consolidated financial statements in the May 12 Form 8-K (CenterPoint Energy Notes) relate to certain contingencies. These notes, as updated herein, are incorporated herein by reference. CenterPoint Energy Notes: Note 3(d) (Long-Lived Assets and Intangibles), Note 3(e) (Regulatory Assets and Liabilities), Note 4 (Regulatory Matters), Note 5 (Derivative Instruments), Note 7 (Indexed Debt Securities (ACES and ZENS) and AOL Time Warner Securities) and Note 13 (Commitments and Contingencies). For information regarding certain legal, tax and regulatory proceedings and environmental matters, see Note 12. 6

(2) DISCONTINUED OPERATIONS Latin America. In February 2003, the Company sold its interest in Argener, a cogeneration facility in Argentina, for $23.1 million. The carrying value of this investment was approximately $11 million as of December 31, 2002. The Company recorded an after-tax gain of $7 million from the sale of Argener in the first quarter of 2003. Revenues related to the Company's Latin America operations included in discontinued operations for the three months ended March 31, 2002 and 2003 were $4.5 million and $1.7 million, respectively. Income from these discontinued operations for the three months ended March 31, 2002 and 2003 is reported net of income tax expense of $3.2 million and $0 million, respectively. Reliant Resources. On September 30, 2002, CenterPoint Energy distributed to its shareholders its 83% ownership interest in Reliant Resources by means of a tax-free spin-off in the form of a dividend. Holders of CenterPoint Energy common stock on the record date received 0.788603 shares of Reliant Resources common stock for each share of CenterPoint Energy stock that they owned on the record date. The Reliant Resources Distribution was recorded in the third quarter of 2002. Reliant Resources' revenues included in discontinued operations for the three months ended March 31, 2002 were $1.8 billion, as reported in Reliant Resources' Annual Report on Form 10-K/A, Amendment No. 1, filed with the SEC on April 30, 2003. Income from these discontinued operations for the three months ended March 31, 2002 is reported net of income tax expense of $43 million. These amounts have been restated to reflect Reliant Resources' adoption of Emerging Issues Task Force (EITF) Issue No. 02-3, "Issues Related to Accounting for Contracts Involved in Energy Trading and Risk Management Activities" during the third quarter of 2002. (3) NEW ACCOUNTING PRONOUNCEMENTS Effective January 1, 2003, the Company adopted SFAS No. 143, "Accounting for Asset Retirement Obligations" (SFAS No. 143). SFAS No. 143 requires the fair value of an asset retirement obligation to be recognized as a liability is incurred and capitalized as part of the cost of the related tangible long-lived assets. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Retirement obligations associated with long-lived assets included within the scope of SFAS No. 143 are those for which a legal obligation exists under enacted laws, statutes and written or oral contracts, including obligations arising under the doctrine of promissory estoppel. The Company has identified retirement obligations for nuclear decommissioning at the South Texas Project Electric Generating Station (South Texas Project) and for lignite mine operations at the Jewett mine supplying the Limestone electric generation facility. Prior to adoption of SFAS No. 143, the Company had recorded liabilities for nuclear decommissioning and the reclamation of the lignite mine. Liabilities were recorded for estimated decommissioning obligations of $139.7 million and $39.7 million for reclamation of the lignite at December 31, 2002. Upon adoption of SFAS No. 143 on January 1, 2003, the Company reversed the $139.7 million previously accrued for the nuclear decommissioning of the South Texas Project and recorded a plant asset of $99.1 million offset by accumulated depreciation of $35.8 million as well as a retirement obligation of $186.7 million. The $16.3 million difference between amounts previously recorded and the amounts recorded upon adoption of SFAS No. 143 is being deferred as a liability due to regulatory requirements. The Company also reversed the $39.7 million it had previously recorded for the Jewett mine reclamation and recorded a plant asset of $1.9 million offset by accumulated depreciation of $0.4 million as well as a retirement obligation of $3.8 million. The $37.4 million difference between amounts previously recorded and the amounts recorded upon adoption of SFAS No. 143 was recorded as a cumulative effect of accounting change. The Company has also identified other asset retirement obligations that cannot be calculated because the assets associated with the retirement obligations have an indeterminate life. 7

The following represents the balances of the asset retirement obligation as of January 1, 2003 and the additions and accretion of the asset retirement obligation for the three months ended March 31, 2003:

The Company's rate-regulated businesses have previously recognized removal costs as a component of depreciation expense in accordance with regulatory treatment. As of March 31, 2003, these previously recognized removal costs of $639 million do not represent SFAS No. 143 asset retirement obligations, but rather embedded regulatory liabilities. The Company's non-rate regulated businesses have also previously recognized removal costs as component of depreciation expense. The Company reversed $115 million in the three months ended March 31, 2003 of previously recognized removal costs with respect to these non-rate-regulated businesses as a cumulative effect of accounting change. The total cumulative effect of accounting change from adoption of SFAS No, 143 was $152 million. Excluded from the $80 million after-tax cumulative effect of accounting change recorded for the three months ended March 31, 2003, is minority interest of $19 million related to the Texas Genco stock not owned by CenterPoint Energy. In April 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections" (SFAS No. 145). SFAS No. 145 eliminates the current requirement that gains and losses on debt extinguishment must be classified as extraordinary items in the income statement. Instead, such gains and losses will be classified as extraordinary items 8

only if they are deemed to be unusual and infrequent. SFAS No. 145 also requires that capital leases that are modified so that the resulting lease agreement is classified as an operating lease be accounted for as a sale-leaseback transaction. The changes related to debt extinguishment are effective for fiscal years beginning after May 15, 2002, and the changes related to lease accounting are effective for transactions occurring after May 15, 2002. The Company has applied this guidance as it relates to lease accounting and the accounting provision related to debt extinguishment. Upon adoption of SFAS No. 145, any gain or loss on extinguishment of debt that was classified as an extraordinary item in prior periods will be reclassified. No such reclassification was required in the three month period ended March 31, 2002. The Company has reclassified the $26 million loss on debt extinguishment related to the fourth quarter of 2002 from an extraordinary item to interest expense. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities" (SFAS No. 146). SFAS No. 146 nullifies EITF Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)" (EITF No. 94-3). The principal difference between SFAS No. 146 and EITF No. 94-3 relates to the requirements for recognition of a liability for costs associated with an exit or disposal activity. SFAS No. 146 requires that a liability be recognized for a cost associated with an exit or disposal activity when it is incurred. A liability is incurred when a transaction or event occurs that leaves an entity little or no discretion to avoid the future transfer or use of assets to settle the liability. Under EITF No. 94-3, a liability for an exit cost was recognized at the date of an entity's commitment to an exit plan. In addition, SFAS No. 146 also requires that a liability for a cost associated with an exit or disposal activity be recognized at its fair value when it is incurred. SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. The Company will apply the provisions of SFAS No. 146 to all exit or disposal activities initiated after December 31, 2002. In November 2002, the FASB issued FASB Interpretation No. (FIN) 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others" (FIN 45). FIN 45 requires that a liability be recorded in the guarantor's balance sheet upon issuance of certain guarantees. In addition, FIN 45 requires disclosures about the guarantees that an entity has issued. The provision for initial recognition and measurement of the liability will be applied on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure provisions of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. The adoption of FIN 45 did not materially affect the Company's consolidated financial statements. In January 2003, the FASB issued FIN 46 "Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51" (FIN 46). FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. The Company does not expect the adoption of FIN 46 to have a material impact on its results of operations or financial condition. (4) REGULATORY MATTERS (a) Excess Cost Over Market (ECOM) True-Up. Texas Genco sells, through auctions, entitlements to substantially all of its installed electric generation capacity, excluding reserves for planned and forced outages. From September 2001 through March 2003, it conducted auctions, as required by the Public Utility Commission of Texas (Texas Utility Commission) and by the Company's master separation agreement with Reliant Resources. Texas Genco will conduct the final auction mandated by the Texas Utility Commission for the purposes of the ECOM True-Up in July 2003. The capacity auctions continue to be consummated at market-based prices that are substantially below the estimate of those prices made by the Texas Utility Commission in the Spring of 2001. The Texas electric restructuring law provides for the recovery in a "true-up" proceeding in 2004 (2004 True-Up Proceeding) of any difference between market power prices and the earlier estimates of those market prices by the Texas Utility Commission, using the prices received in the auctions required by the Texas Utility Commission as the measure of 9

market prices (ECOM True-Up). For the three months ended March 31, 2002 and 2003, CenterPoint Energy recorded approximately $141 million and $132 million, respectively, in non-cash revenue related to the cost recovery of the difference between the market power prices and the Texas Utility Commission's earlier estimates. For additional information regarding the capacity auctions and the related true-up proceeding, please read Notes 3(e) and 4(a) to the CenterPoint Energy Notes, which are incorporated herein by reference. (b) Generation Asset Impairment Contingency. The Company evaluates the recoverability of its long-lived assets in accordance with SFAS No. 144. As of March 31, 2003, no impairment had been indicated in its Texas generation assets. The Company anticipates that future events, such as changes in the market value of the Texas Genco stock, a change in the estimated holding period of the Texas generation assets, or a change in market demand for electricity, will require the Company to re-evaluate these assets for impairment between now and 2004. If an impairment is indicated, it could be material and may not be fully recoverable through the 2004 True-Up Proceeding. The Texas electric restructuring law provides for the Company to recover the regulatory book value of its Texas generating assets (as defined in the Texas electric restructuring law) to the extent the regulatory book value exceeds the estimated market value. If the Texas generating assets are sold in the future, a loss on sale of these assets, or an impairment of the recorded recoverable electric generation plant mitigation regulatory asset, will occur to the extent the recorded book value of the Texas generating assets exceeds the regulatory book value. As of March 31, 2003, the recorded book value was $518 million in excess of the regulatory book value. This amount declines as the recorded book value is depreciated and increases by the amount of non-environmental capital expenditures incurred prior to May 1, 2003. For further discussion of the difference between the regulatory book value and the recorded book value, see Note 4(a) to the CenterPoint Energy Notes. (c) Regulatory Assets Contingency. As of March 31, 2003, in contemplation of the 2004 True-Up Proceeding, CenterPoint Houston has recorded a regulatory asset of $2.5 billion representing the estimated future recovery of previously incurred stranded costs. This amount includes $1.1 billion of previously recorded accelerated depreciation (an amount equal to earnings above a stated overall annual rate of return on invested capital that was used to recover the Company's investment in generation assets) and redirected depreciation of $841 million, both reversed in 2001 as well as $396 million related to the Texas Genco distribution as discussed in Note 1. Offsetting this regulatory asset is a $932 million regulatory liability to refund the excess mitigation to ratepayers. This estimated recovery is based upon current projections of the market value of the Company's Texas generation assets to be covered by the 2004 True-Up Proceeding calculations. The regulatory liability reflects a current refund obligation arising from prior mitigation of stranded costs deemed excessive by the Texas Utility Commission. CenterPoint Houston began refunding excess mitigation credits with January 2002 bills. These credits are to be refunded over a seven-year period. Because GAAP requires CenterPoint Houston to estimate fair market values in advance of the final reconciliation, the financial impacts of the Texas electric restructuring law with respect to the final determination of stranded costs in the 2004 True-Up Proceeding are subject to material changes. Factors affecting such changes may include estimation risk, uncertainty of future energy and commodity prices and the economic lives of the plants. If events were to occur that made the recovery of some of the remaining generation related regulatory assets no longer probable, the Company would write off the unrecoverable balance of such assets as a charge against earnings. (d) Fuel Reconciliation Contingency. CenterPoint Houston and Texas Genco filed their joint application to reconcile fuel revenues and expenses with the Texas Utility Commission on July 1, 2002. This final fuel reconciliation filing covers reconcilable fuel revenue, fuel expense and interest of approximately $8.5 billion incurred from August 1, 1997 through January 30, 2002. Also included in this amount is an under-recovery of $94 million, which was the balance at July 31, 1997 as approved in CenterPoint Houston's last fuel reconciliation. On March 3, 2003, a settlement agreement was filed under which certain items totaling $24 million would be written off during the fourth quarter of 2002 and items totaling $203 million would be carried forward for resolution by the Texas Utility Commission in late 2003 or early 2004. 10

(5) DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to various market risks. These risks arise from transactions entered into in the normal course of business. The Company utilizes derivative financial instruments such as physical forward contracts, swaps and options (Energy Derivatives) to mitigate the impact of changes in cash flows of its natural gas businesses on its operating results and cash flows. Cash Flow Hedges. During the three months ended March 31, 2003, no hedge ineffectiveness was recognized in earnings from derivatives that are designated and qualify as cash flow hedges. No component of the derivative instruments' gain or loss was excluded from the assessment of effectiveness. During the three months ended March 31, 2003, there was no effect on earnings as a result of the discontinuance of cash flow hedges. As of March 31, 2003, the Company expects $2.3 million in accumulated other comprehensive income to be reclassified into net income during the next twelve months. Interest Rate Swaps. As of March 31, 2003, the Company had outstanding interest rate swaps with an aggregate notional amount of $750 million to fix the interest rate applicable to floating rate long-term debt. These swaps do not qualify as cash flow hedges under SFAS No. 133, and are marked to market in the Company's Consolidated Balance Sheets with changes reflected in interest expense in the Statements of Consolidated Income. During 2002, the Company settled its forward-starting interest rate swaps having a notional amount of $1.5 billion at a cost of $156 million, which was recorded in other comprehensive income, and reclassified $36 million to interest expense in 2002 as a result of interest payments it believes are no longer probable of occurring for certain periods including the first three months of 2003. The remaining $120 million in other comprehensive income will be amortized into interest expense in the same period during which the forecasted payments affect earnings. No amortization of this amount was recognized in the first three months of 2003. Based on the expected timing of the forecasted transactions hedged by the forward-starting interest rate swaps, amortization of amounts deferred in accumulated other comprehensive income will be amortized into earnings beginning in April 2003 and are expected to amount to $11.9 million in 2003. (6) GOODWILL AND INTANGIBLES The components of the Company's other intangible assets consist of the following:

DECEMBER 31, 2002 MARCH 31, 2003 ----------------------------- ----------------------------- CARRYING ACCUMULATED CARRYING ACCUMULATED AMOUNT AMORTIZATION AMOUNT AMORTIZATION ------------ ------------ ------------ ------------ (IN MILLIONS) Land use rights ......... $ 61 $ (12) $ 61 $ (12) Other ................... 19 (2) 20 (3) ------------ ------------ ------------ ------------ Total ............... $ 80 $ (14) $ 81 $ (15) ============ ============ ============ ============
The Company recognizes specifically identifiable intangibles, including land use rights and permits, when specific rights and contracts are acquired. The Company has no intangible assets with indefinite lives recorded as of March 31, 2003. The Company amortizes other acquired intangibles on a straight-line basis over the lesser of their contractual or estimated useful lives that range from 40 to 75 years for land use rights and 4 to 25 years for other intangibles. Amortization expense for other intangibles for the three months ended March 31, 2002 and 2003 was $0.4 million and $0.5 million, respectively. Estimated amortization expense for the remainder of 2003 and the five succeeding fiscal years is as follows (in millions): 11

(8) CAPITAL STOCK CenterPoint Energy has 1,020,000,000 authorized shares of capital stock, comprised of 1,000,000,000 shares of $0.01 par value common stock and 20,000,000 shares of $0.01 par value preferred stock. At December 31, 2002, 305,017,330 shares of CenterPoint Energy common stock were issued and 300,101,587 shares of CenterPoint Energy common stock were outstanding. At March 31, 2003, 305,436,836 shares of CenterPoint Energy common stock were issued and 301,664,118 shares of CenterPoint Energy common stock were outstanding. Outstanding common shares exclude (a) shares pledged to secure a loan to CenterPoint Energy's Employee Stock Ownership Plan (4,915,577 and 3,772,552 at December 31, 2002 and March 31, 2003, respectively) and (b) treasury shares (166 at both December 31, 2002 and March 31, 2003). Reliant Energy declared a dividend of $0.375 per share in the first quarter of 2002 and CenterPoint Energy declared a dividend of $0.10 per share in the first quarter of 2003. (9) SHORT-TERM BORROWINGS, LONG-TERM DEBT AND RECEIVABLES FACILITY (a) Short-term Borrowings. Credit Facilities. As of March 31, 2003, a subsidiary of CenterPoint Energy had credit facilities that provided for an aggregate of $200 million in committed credit that is classified as short-term. As of March 31, 2003, such credit facilities were not utilized. As of March 31, 2003, cash aggregating $279 million was invested in a money market fund. On February 28, 2003, the Company's $3.85 billion bank facility was amended and extended to June 2005 as discussed below in " -- Long-term Debt." Loans under this facility are recorded as long-term debt in the Consolidated Balance Sheets at both December 31, 2002 and March 31, 2003. 12

On March 25, 2003, CERC obtained a $200 million revolving credit facility referenced above that terminates on March 23, 2004. Rates for borrowings under this facility, including the facility fee, are LIBOR plus 250 basis points based on current credit ratings and the applicable pricing grid. There were no amounts outstanding under this facility as of March 31, 2003. The bank facilities contain various business and financial covenants. The borrowers are currently in compliance with the covenants under the applicable credit agreements. (b) Long-term Debt. On February 28, 2003, the Company reached agreement with a syndicate of banks on a second amendment to its $3.85 billion bank facility (Second Amendment). Under the Second Amendment, the maturity date of the bank facility was extended from October 2003 to June 30, 2005, and the $1.2 billion in mandatory prepayments that would have been required in 2003 (including $600 million due on February 28, 2003) were eliminated. At the time of the Second Amendment, the facility consisted of a $2.35 billion term loan and a $1.5 billion revolver. In March 2003, a $50 million repayment of the term loan reduced the term loan to $2.30 billion. At March 31, 2003, the revolver was fully utilized. Borrowings bear interest based on LIBOR rates under a pricing grid tied to the Company's credit rating. At the Company's current credit ratings, the pricing for loans remains the same. The drawn cost for the facility at the Company's current ratings is LIBOR plus 450 basis points. The Company has agreed to pay the banks an extension fee of 75 basis points on the amounts outstanding under the bank facility on October 9, 2003. The Company also paid $41 million in fees that were due on February 28, 2003, along with $20 million in fees that had been due on June 30, 2003. In addition, the interest rate will be increased by 25 basis points beginning May 28, 2003 if the Company does not grant the banks a security interest in its 81% stock ownership of Texas Genco. Granting the security interest in the stock of Texas Genco requires approval from the SEC under the 1935 Act, which is currently being sought. That security interest would be released at the time of a sale of Texas Genco, which may occur as early as 2004. Proceeds from any sale will be used to reduce the bank facility. Also under the Second Amendment, on or before May 28, 2003, the Company agreed to grant to the banks warrants to purchase up to 10%, on a fully diluted basis, of its common stock at a price equal to the greater of $6.56 per share or 110% of the closing price on the New York Stock Exchange on the date the warrants are issued. The warrants would not be exercisable for a year after issuance but would remain outstanding for four years; provided, that if the Company reduces the term loans owed under the bank facility during 2003 by specified amounts, the warrants will be extinguished. To the extent that the Company reduces the term loans owed under the bank facility by up to $400 million on or before May 28, 2003, up to half of the warrants will be extinguished on a basis proportionate to the reduction in the credit facility. To the extent such warrants are not extinguished on or before May 28, 2003, they will vest and become exercisable in accordance with their terms. At March 31, 2003, the Company had reduced the term loans owed under the bank facility by $50 million. Whether or not the Company is able to extinguish warrants on or before May 28, 2003, the remaining 50% of the warrants will be extinguished, again on a proportionate basis, if the Company reduces the term loans owed under the bank facility by up to $400 million by the end of 2003. The Company plans to eliminate the warrants entirely before they vest by accessing the capital markets to fund the total payments of $800 million during 2003; however, there can be no assurance that the Company will be able to extinguish the warrants or to do so on favorable terms. The warrants and the underlying common stock would be registered with the SEC and could be exercised either through the payment of the purchase price or on a "cashless" basis under which the Company would issue a number of shares based upon the difference between the then-current market price and the warrant exercise price. Issuance of the warrants is also subject to obtaining SEC approval under the 1935 Act, which is currently being sought. If that approval is not obtained on or before May 28, 2003, the Company will provide the banks equivalent cash compensation over the term that its warrants would have been exercisable to the extent they are not otherwise extinguished. In the Second Amendment, the Company also agreed that its quarterly common stock dividend will not exceed $0.10 per share. If the Company has not reduced the bank facility by a total of at least $400 million by the end of 2003, of which at least $200 million has come from the issuance of capital stock or securities linked to capital stock (such as convertible debt), the maximum dividend payable during 2004 and for the balance of the term of the facility 13

is subject to an additional test. Under that test the maximum permitted quarterly dividend will be the lesser of (i) $0.10 per share or (ii) 12.5% of the Company's net income per share for the 12 months ended on the last day of the previous quarter. The Second Amendment provides that proceeds from capital stock or indebtedness issued or incurred by the Company must be applied (subject to a $200 million basket for CERC and another $250 million basket for borrowings by the Company, certain permitted refinancings of existing debt and other limited exceptions) to repay bank loans and permanently reduce the bank facility. Similarly, cash proceeds from the sale of assets of more than $30 million or, if less, a group of sales aggregating more than $100 million, must be applied to repay bank loans and reduce the bank facility, except that proceeds of up to $120 million can be reinvested in the Company's businesses. On March 18, 2003, CenterPoint Houston issued $762.3 million aggregate principal amount of general mortgage bonds composed of $450 million principal amount of 10-year bonds with an interest rate of 5.7% and $312.3 million principal amount of 30-year bonds with an interest rate of 6.95%. Proceeds were used to repay $150 million aggregate principal amount of medium-term notes maturing on April 21, 2003, to redeem approximately $312.3 million aggregate principal amount of CenterPoint Houston's first mortgage bonds and to repay $279 million of a $537 million intercompany note payable to CenterPoint Energy by CenterPoint Houston. Proceeds from the note repayment were ultimately used by CenterPoint Energy to repay borrowings under CenterPoint Energy's $3.85 billion credit facility and to permanently reduce the term loan component of the credit facility by $50 million. On March 25 and April 14, 2003, CERC issued $650 million and $112 million, respectively, aggregate principal amount of 7.875% senior unsecured notes due in 2013. A portion of the proceeds were used to refinance $360 million aggregate principal amount of CERC's 6 3/8% Term Enhanced ReMarketable Securities (TERM Notes) and to pay costs associated with the refinancing. Proceeds were also used to repay borrowings under CERC's $350 million revolving credit facility prior to its expiration on March 31, 2003. The remaining $140 million aggregate principal amount of TERM Notes are due to be refinanced or remarketed in November 2003. On April 9, 2003, the Company remarketed $175 million aggregate principal amount of pollution control bonds that it had owned since the fourth quarter of 2002. Remarketed bonds maturing in 2029 have a principal amount of $75 million and an interest rate of 8%. Remarketed bonds maturing in 2018 have a principal amount of $100 million and an interest rate of 7.75%. Proceeds from the remarketing were used to repay bank debt. At December 31, 2002, the $175 million of bonds owned by the Company were not reflected as outstanding debt in the Company's Consolidated Balance Sheets. (c) Receivables Facility. In connection with CERC's November 2002 amendment and extension of its $150 million receivables facility, CERC Corp. formed a bankruptcy remote subsidiary for the sole purpose of buying and selling receivables created by CERC. This transaction is accounted for as a sale of receivables under the provisions of SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," and, as a result, the related receivables are excluded from the Consolidated Balance Sheets. As of December 31, 2002 and March 31, 2003, CERC had utilized $107 million and $150 million of its receivables facility, respectively. 14

(10) TRUST PREFERRED SECURITIES (a) CenterPoint Energy. Statutory business trusts created by CenterPoint Energy have issued trust preferred securities, the terms of which, and the related series of junior subordinated debentures, are described below (in millions):

AGGREGATE LIQUIDATION AMOUNTS AS OF DECEMBER 31, MANDATORY 2002 AND DISTRIBUTION REDEMPTION MARCH 31, 2003 RATE/ DATE/ TRUST (IN MILLIONS) INTEREST RATE MATURITY DATE JUNIOR SUBORDINATED DEBENTURES ------------------------- -------------- ------------- -------------- ------------------------------- REI Trust I.............. $ 375 7.20% March 2048 7.20% Junior Subordinated Debentures HL&P Capital Trust I..... $ 250 8.125% March 2046 8.125% Junior Subordinated Deferrable Interest Debentures Series A HL&P Capital Trust II.... $ 100 8.257% February 2037 8.257% Junior Subordinated Deferrable Interest Debentures Series B

The sole asset of each trust consists of junior subordinated debentures of CenterPoint Energy having interest rates and maturity dates that correspond to the distribution rates and the mandatory redemption dates for each series of preferred securities or capital securities, and the principal amounts corresponding to the common and preferred securities or capital securities issued by that trust. (b) CERC Corp. A statutory business trust created by CERC Corp. has issued convertible preferred securities. The convertible preferred securities are mandatorily redeemable upon the repayment of the convertible junior subordinated debentures at their stated maturity or earlier redemption. Effective January 7, 2003, the convertible preferred securities are convertible at the option of the holder into $33.62 of cash and 2.34 shares of CenterPoint Energy common stock for each $50 of liquidation value. As of December 31, 2002 and March 31, 2003, $0.4 million liquidation amount of convertible preferred securities were outstanding. The securities, and their underlying convertible junior subordinated debentures, bear interest at 6.25% and mature in June 2026. The sole asset of the trust consists of convertible junior subordinated debentures of CERC having an interest rate and maturity date that correspond to the distribution rate and the mandatory redemption date of the convertible preferred securities, and the principal amount corresponding to the common and convertible preferred securities issued by the trust. For additional information regarding these securities, see Note 10 to the CenterPoint Energy Notes, which note is incorporated herein by reference. 15

(11) STOCK-BASED INCENTIVE COMPENSATION PLANS In accordance with SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123), and SFAS No. 148, "Accounting for Stock-Based Compensation, Transition and Disclosure -- an Amendment of SFAS No. 123," the Company applies the guidance contained in Accounting Principles Board Opinion No. 25 and discloses the required pro forma effect on net income of the fair value based method of accounting for stock compensation. Pro forma information for the three months ended March 31, 2002 and 2003 is provided to take into account the amortization of stock-based compensation to expense on a straight-line basis over the vesting period. Had compensation costs been determined as prescribed by SFAS No. 123, the Company's net income and earnings per share would have been as follows:

(12) COMMITMENTS AND CONTINGENCIES (a) Legal Matters. The Company's predecessor, Reliant Energy, and certain of its former subsidiaries are named as defendants in several lawsuits described below. Under a master separation agreement between Reliant Energy and Reliant Resources, the Company and its subsidiaries are entitled to be indemnified by Reliant Resources for any losses arising out of the lawsuits described under "California Class Actions and Attorney General Cases," "Long-Term Contract Class Action," "Washington and Oregon Class Actions," "Bustamante Price Reporting Class Action," "Gas Trading Class Action" and "Trading and Marketing Activities," including attorneys' fees and other costs. Pursuant to the indemnification obligation, Reliant Resources is defending the Company and its subsidiaries to the extent named in these lawsuits. The ultimate outcome of these matters cannot be predicted at this time. California Class Actions and Attorney General Cases. Reliant Energy, Reliant Resources, Reliant Energy Power Generation, Inc. (REPG) and several other subsidiaries of Reliant Resources, as well as two former officers and one present officer of some of these companies, have been named as defendants in class action lawsuits and other lawsuits filed against a number of companies that own generation plants in California and other sellers of electricity in California markets. While the plaintiffs allege various violations by the defendants of antitrust laws and state laws against unfair and unlawful business practices, each of the lawsuits is grounded on the central allegation that the defendants conspired to drive up the wholesale price of electricity. In addition to injunctive relief, the plaintiffs in these lawsuits seek treble the amount of damages alleged, restitution of alleged overpayments, disgorgement of alleged unlawful profits for sales of electricity, costs of suit and attorneys' fees. The first six of these suits originally were filed in state courts in San Diego, San Francisco and Los Angeles Counties. The suits in San Diego and Los Angeles Counties were consolidated and removed to the federal district court in San Diego, but on December 13, 2002, that court remanded the suits to the state courts. Prior to the remand, Reliant Energy was voluntarily dismissed from two of the suits. Several parties, including the Reliant defendants, have appealed the judge's remand decision. The United States court of appeals has entered a briefing schedule that could result in oral arguments by summer of 16

2003 and stayed the remand order pending the appeal. In March and April 2002, the California Attorney General filed three complaints, two in state court in San Francisco and one in the federal district court in San Francisco, against Reliant Energy, Reliant Resources, Reliant Energy Services and other subsidiaries of Reliant Resources alleging, among other matters, violations by the defendants of state laws against unfair and unlawful business practices arising out of transactions in the markets for ancillary services run by the California independent systems operator, charging unjust and unreasonable prices for electricity, in violation of antitrust laws in connection with the acquisition in 1998 of electric generating facilities located in California. The complaints variously seek restitution and disgorgement of alleged unlawful profits for sales of electricity, civil penalties and fines, injunctive relief against unfair competition, divestment of Reliant Resources' generation capacity and undefined equitable relief. Reliant Resources removed the two state court cases to the federal district court in San Francisco. In August 2002, the district court dismissed the two cases originally filed in state court and also dismissed the damages claims asserted in the antitrust case. The Attorney General has appealed the dismissal of these cases to the court of appeals. Following the filing of the Attorney General cases, seven additional class action cases were filed in state courts in Northern California. Each of these purports to represent the same class of California ratepayers, assert the same claims as asserted in the other California class action cases, and in some instances repeat as well the allegations in the Attorney General cases. All of these cases have been removed to federal district court in San Diego. Reliant Resources has not filed an answer in any of these cases. In all of these cases pending before the federal and state courts in California, the Reliant defendants have filed or intend to file motions to dismiss on grounds that the claims are barred by federal preemption and the filed rate doctrine. Long-Term Contract Class Action. In October 2002, a class action was filed in state court in Los Angeles against Reliant Energy and several subsidiaries of Reliant Resources. The complaint in this case repeats the allegations asserted in the California class actions as well as the Attorney General cases and also alleges misconduct related to long-term contracts purportedly entered into by the California Department of Water Resources. None of the Reliant entities, however, has a long-term contract with the Department of Water Resources. This case has been removed to federal district court in San Diego. The Reliant defendants intend to file motions to dismiss on grounds that the claims are barred by federal preemption and the filed rate doctrine. Washington and Oregon Class Actions. In December 2002, a lawsuit was filed in Circuit Court of the State of Oregon for the County of Multnomah on behalf of a class of all Oregon purchasers of electricity and natural gas. Reliant Energy, Reliant Resources and several Reliant Resources subsidiaries are named as defendants, along with many other electricity generators and marketers. Like the other lawsuits filed in California, the plaintiffs claim the defendants manipulated wholesale power prices in violation of state and federal law. The plaintiffs seek injunctive relief and payment of damages based on alleged overcharges for electricity. Also in December 2002, a nearly identical lawsuit on behalf of consumers in the State of Washington was filed in federal district court in Seattle. Reliant Resources has removed the Oregon suit to federal district court in Portland. It is anticipated that before answering the lawsuits, the defendants will file motions to dismiss on the grounds that the claims are barred by federal preemption and by the filed rate doctrine. Bustamante Price Reporting Class Action. In November 2002, California Lieutenant Governor Cruz Bustamante filed a lawsuit in state court in Los Angeles on behalf of a class of purchasers of gas and power alleging violations of state antitrust laws and state laws against unfair and unlawful business practices based on an alleged conspiracy to report and publish false and fraudulent natural gas prices with an intent to affect the market prices of natural gas and electricity in California. Reliant Energy, Reliant Resources and several Reliant Resources subsidiaries are named as defendants, along with other market participants and publishers of some of the price indices. The complaint seeks injunctive relief, compensatory and punitive damages, restitution of alleged overpayment, disgorgement of all profits and funds acquired by the alleged unlawful conduct, costs of suit and attorneys' fees. The Reliant defendants intend to deny both their alleged violation of any laws and their alleged participation in any conspiracy. Gas Trading Class Action. The Company, Reliant Resources and Reliant Energy, have been named as defendants in a lawsuit filed in April 2003 in state court in Los Angeles County, California on behalf 17

of a class of purchasers of natural gas alleging violations of state antitrust laws and state laws against unfair and unlawful business practices based on an alleged conspiracy with Enron Corp. to manipulate the California natural gas markets in 2000 and 2001. The complaint is based on certain conclusions in a report by the staff of the Federal Energy Regulatory Commission that has not been subject to procedures designed to allow parties to either discover or test the basis for the conclusions. The complaint seeks injunctive and declaratory relief, compensatory and punitive damages, restitution, costs of suit and attorneys' fees. The complaint alleges that there were "well over one billion dollars in excess charges to California consumers during the 2000 through 2001 time period." The plaintiffs are seeking a trebling of any damages award. While Reliant Resources has not yet filed an answer, the Company understands that Reliant Resources intends to deny both the alleged violation of any laws and the participation in a conspiracy with Enron. Neither the Company nor Reliant Energy was a party in the proceedings in which the report was submitted. Further, neither the Company nor any of its current subsidiaries has ever engaged in gas trading in California. Trading and Marketing Activities. Reliant Energy has been named as a party in several lawsuits and regulatory proceedings relating to the trading and marketing activities of its former subsidiary, Reliant Resources. In June 2002, the SEC advised Reliant Resources and Reliant Energy that it had issued a formal order in connection with its investigation of Reliant Resources' and Reliant Energy's financial reporting, internal controls and related matters. The Company understands that the investigation is focused on Reliant Resources' same-day commodity trading transactions involving purchases and sales with the same counterparty for the same volume at substantially the same price and certain structured transactions. These matters were previously the subject of an informal inquiry by the SEC. On May 12, 2003, the SEC advised Reliant Resources and Reliant Energy that it had issued a formal order in connection with this investigation. Reliant Energy, through its successor and our subsidiary, CenterPoint Houston, has entered into a settlement with the SEC that concludes this investigation. Under the settlement, Reliant Resources and Reliant Energy consented to the entry of an administrative cease-and-desist order with respect to future violations of certain provisions of the Securities Act of 1933 and the Securities Exchange Act of 1934, without admitting or denying the SEC's findings that violations of these laws had occurred. The SEC did not assess monetary penalties or fines against Reliant Energy, us or any of our subsidiaries. In connection with the Texas Utility Commission's industry-wide investigation into potential manipulation of the ERCOT market on and after July 31, 2001, Reliant Energy and Reliant Resources have provided information to the Texas Utility Commission concerning their scheduling and trading activities. Fifteen class action lawsuits filed in May, June and July 2002 on behalf of purchasers of securities of Reliant Resources and/or Reliant Energy have been consolidated in federal district court in Houston. Reliant Resources and certain of its former and current executive officers are named as defendants. Reliant Energy is also named as a defendant in seven of the lawsuits. Two of the lawsuits also name as defendants the underwriters of the Reliant Resources initial public offering (Reliant Resources Offering). One lawsuit names Reliant Resources' and Reliant Energy's independent auditors as a defendant. The consolidated amended complaint seeks monetary relief purportedly on behalf of three classes: (1) purchasers of Reliant Energy common stock from February 3, 2000 to May 13, 2002; (2) purchasers of Reliant Resources common stock on the open market from May 1, 2001 to May 13, 2002; and (3) purchasers of Reliant Resources common stock in the Reliant Resources Offering or purchasers of shares that are traceable to the Reliant Resources Offering. The plaintiffs allege, among other things, that the defendants misrepresented their revenues and trading volumes by engaging in round-trip trades and improperly accounted for certain structured transactions as cash-flow hedges, which resulted in earnings from these transactions being accounted for as future earnings rather than being accounted for as earnings in fiscal year 2001. In February 2003, a lawsuit was filed by three individuals in federal district court in Chicago against CenterPoint Energy and certain former and current officers of Reliant Resources for alleged violations of federal securities laws. The plaintiffs in this lawsuit allege that the defendants violated federal securities laws by issuing false and misleading statements to the public, and that the defendants made false and misleading statements as part of an alleged scheme to inflate artificially trading volumes and revenues. In addition, the plaintiffs assert claims of fraudulent and negligent misrepresentation and violations of Illinois consumer law. The defendants expect to file a motion to transfer this lawsuit to the federal district court in Houston and to consolidate this lawsuit with the consolidated lawsuits described above. 18

The Company believes that none of these lawsuits has merit because, among other reasons, the alleged misstatements and omissions were not material and did not result in any damages to any of the plaintiffs. In May 2002, three class action lawsuits were filed in federal district court in Houston on behalf of participants in various employee benefits plans sponsored by Reliant Energy. Reliant Energy and its directors are named as defendants in all of the lawsuits. Two of the lawsuits have been dismissed without prejudice. The remaining lawsuit alleges that the defendants breached their fiduciary duties to various employee benefits plans, directly or indirectly sponsored by Reliant Energy, in violation of the Employee Retirement Income Security Act. The plaintiffs allege that the defendants permitted the plans to purchase or hold securities issued by Reliant Energy when it was imprudent to do so, including after the prices for such securities became artificially inflated because of alleged securities fraud engaged in by the defendants. The complaints seek monetary damages for losses suffered by a putative class of plan participants whose accounts held Reliant Energy or Reliant Resources securities, as well as equitable relief in the form of restitution. In October 2002, a derivative action was filed in the federal district court in Houston, against the directors and officers of the Company. The complaint sets forth claims for breach of fiduciary duty, waste of corporate assets, abuse of control and gross mismanagement. Specifically, the shareholder plaintiff alleges that the defendants caused the Company to overstate its revenues through so-called "round trip" transactions. The plaintiff also alleges breach of fiduciary duty in connection with the spin-off and the Reliant Resources Offering. The complaint seeks monetary damages on behalf of the Company as well as equitable relief in the form of a constructive trust on the compensation paid to the defendants. On March 13, 2003, the court dismissed this case on the grounds that the plaintiff did not make an adequate demand on the Company before filing suit. On March 26, 2003, the plaintiff sent another demand asserting the same claims. The Company's board of directors is investigating that demand and similar allegations made in a June 28, 2002 demand letter sent on behalf of a Company shareholder. The latter letter states that the shareholder and other shareholders are considering filing a derivative suit on behalf of the Company and demands that the Company take several actions in response to alleged round-trip trades occurring in 1999, 2000, and 2001. The Board is reviewing the demands made by the shareholders to determine if these proposed actions are in the best interests of the Company. Reliant Energy Municipal Franchise Fee Lawsuits. In February 1996, the cities of Wharton, Galveston and Pasadena filed suit, for themselves and a proposed class of all similarly situated cities in Reliant Energy's electric service area, against Reliant Energy and Houston Industries Finance, Inc. (formerly a wholly owned subsidiary of Reliant Energy) alleging underpayment of municipal franchise fees. The plaintiffs claim that they are entitled to 4% of all receipts of any kind for business conducted within these cities over the previous four decades. A jury trial of the original claimant cities (but not the class of cities) in the 269th Judicial District Court for Harris County, Texas, ended in April 2000 (the Three Cities case). Although the jury found for Reliant Energy on many issues, it found in favor of the original claimant cities on three issues, and assessed a total of $4 million in actual and $30 million in punitive damages. However, the jury also found in favor of Reliant Energy on the affirmative defense of laches, a defense similar to a statute of limitations defense, due to the original claimant cities having unreasonably delayed bringing their claims during the 43 years since the alleged wrongs began. The trial court in the Three Cities case granted most of Reliant Energy's motions to disregard the jury's findings. The trial court's rulings reduced the judgment to $1.7 million, including interest, plus an award of $13.7 million in legal fees. In addition, the trial court granted Reliant Energy's motion to decertify the class. Following this ruling, 45 cities filed individual suits against Reliant Energy in the District Court of Harris County. On February 27, 2003, the state court of appeals in Houston rendered an opinion reversing the judgment against the Company and rendering judgment that the Three Cities take nothing by their claims. The court of appeals found that the jury's finding of laches barred all of the Three Cities' claims and that the Three Cities were not entitled to recovery of any attorneys' fees. The judgment of the court of appeals is subject to an appeal to the Texas Supreme Court. The extent to which issues in the Three Cities case may affect the claims of the other cities served by Reliant Energy cannot be assessed until judgments are final and no longer subject to appeal. However, the court of appeals' ruling appears to be consistent with Texas Supreme Court opinions. The Company estimates the range of possible outcomes for recovery by the plaintiffs in the Three Cities case to be between $-0- and $18 million inclusive of 19

interest and attorneys' fees. Natural Gas Measurement Lawsuits. In 1997, a suit was filed under the Federal False Claims Act against RERC Corp. (now CERC Corp.) and certain of its subsidiaries alleging mismeasurement of natural gas produced from federal and Indian lands. The suit seeks undisclosed damages, along with statutory penalties, interest, costs, and fees. The complaint is part of a larger series of complaints filed against 77 natural gas pipelines and their subsidiaries and affiliates. An earlier single action making substantially similar allegations against the pipelines was dismissed by the federal district court for the District of Columbia on grounds of improper joinder and lack of jurisdiction. As a result, the various individual complaints were filed in numerous courts throughout the country. This case has been consolidated, together with the other similar False Claims Act cases, in the federal district court in Cheyenne, Wyoming. In addition, CERC Corp., CenterPoint Energy Gas Transmission Company, CenterPoint Energy Field Services, Inc., and CenterPoint Energy-Mississippi River Transmission Corporation are defendants in a class action filed in May 1999 against approximately 245 pipeline companies and their affiliates. The plaintiffs in the case purport to represent a class of natural gas producers and fee royalty owners who allege that they have been subject to systematic gas mismeasurement by the defendants for more than 25 years. The plaintiffs seek compensatory damages, along with statutory penalties, treble damages, interest, costs and fees. On April 10, 2003, the judge denied the plaintiffs' motion to certify the requested class. Plaintiffs have requested and secured 30 days to amend their petition and may seek to redefine the class to comply with the judge's findings. The action is currently pending in state court in Stevens County, Kansas. City of Tyler, Texas, Gas Costs Review. By letter to CenterPoint Energy Entex (Entex) dated July 31, 2002, the City of Tyler, Texas, forwarded various computations of what it believes to be excessive costs ranging from $2.8 million to $39.2 million for gas purchased by Entex for resale to residential and small commercial customers in that city under supply agreements in effect since 1992. Entex's gas costs for its Tyler system are recovered from customers pursuant to tariffs approved by the city and filed with both the city and the Railroad Commission of Texas (the Railroad Commission). Pursuant to an agreement, on January 29, 2003, Entex and the city filed a Joint Petition for Review of Charges for Gas Sales (Joint Petition) with the Railroad Commission. The Joint Petition requests that the Railroad Commission determine whether Entex has properly and lawfully charged and collected for gas service to its residential and commercial customers in its Tyler distribution system for the period beginning November 1, 1992, and ending October 31, 2002. The Company believes that all costs for Entex's Tyler distribution system have been properly included and recovered from customers pursuant to Entex's filed tariffs and that the city has no legal or factual support for the statements made in its letter. Gas Cost Recovery Suits. In October 2002, a suit was filed in state district court in Wharton County, Texas against the Company, CERC, Entex Gas Marketing Company, and others alleging fraud, violations of the Texas Deceptive Trade Practices Act, violations of the Texas Utility Code, civil conspiracy and violations of the Texas Free Enterprise and Antitrust Act. The plaintiffs seek class certification, but no class has been certified. The plaintiffs allege that defendants inflated the prices charged to certain consumers of natural gas. In February 2003, a similar suit was filed against CERC in state court in Caddo Parish, Louisiana purportedly on behalf of a class of residential or business customers in Louisiana who allegedly have been overcharged for gas or gas service provided by CERC. The plaintiffs in both cases seek restitution for the alleged overcharges, exemplary damages and penalties. The Company denies that CERC has overcharged any of its customers for natural gas and believes that the amounts recovered for purchased gas have been in accordance with what is permitted by state regulatory authorities. Supplier Suits. Texas Genco is currently engaged in a dispute with its fuel supplier at its Limestone electric generation facility over the terms and pricing for fuel supplied to that facility under a 1999 settlement agreement between the parties and under ancillary obligations. On May 6, 2003, Texas Genco filed suit for a declaratory judgment against the supplier, Northwestern Resources Co. (NWR), in Harris County, Texas, and NWR filed similar claims for a declaratory judgment in an action previously filed against Reliant Energy in Limestone County, Texas. NWR claims Texas Genco has breached its obligations by modifying its generation facility to burn coal from the Powder River Basin and by purchasing coal from the Powder River Basin without first giving NWR a right of first refusal to supply lignite at a price that is equal to or less than coal from the Powder River Basin. NWR also contends that Texas Genco is not entitled to certain production royalties. In its suit, Texas Genco seeks rulings that it has not breached its obligations regarding the modification of its facilities and the burning of Powder River Basin coal but that, instead, NWR has breached its 20

obligations by failing to pay production royalties and in other respects. The ultimate outcome of this dispute cannot be determined at this time. Other Proceedings. The Company is involved in other proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. The Company's management currently believes that the disposition of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows. (b) Environmental Matters. Clean Air Standards. The Texas electric restructuring law and regulations adopted by the Texas Commission on Environmental Quality in 2001 require substantial reductions in emission of oxides of nitrogen (NOx) from electric generating units. The Company is currently installing cost-effective controls at its generating plants to comply with these requirements. Through March 31, 2003, the Company has invested $582 million for NOx emission control, and plans to make expenditures of up to approximately $200 million for the remainder of 2003 through 2007. The Texas electric restructuring law provides for stranded cost recovery for expenditures incurred before May 1, 2003 to achieve the NOx reduction requirements. Incurred costs include costs for which contractual obligations have been made. The Texas Utility Commission has determined that the Company's emission control plan is the most cost-effective option for achieving compliance with applicable air quality standards for the Company's generating facilities and the final amount for recovery will be determined in the 2004 True-Up Proceeding. Hydrocarbon Contamination. On August 24, 2001, 37 plaintiffs filed suit against Reliant Energy Gas Transmission Company (REGT), Reliant Energy Pipeline Services, Inc., RERC Corp., RES, other Reliant Energy entities and third parties in the 1st Judicial District Court, Caddo Parish, Louisiana. The petition has now been supplemented seven times. As of May 1, 2003, there were 572 plaintiffs, a majority of whom are Louisiana residents. In addition to the Reliant Energy entities, the plaintiffs have sued the State of Louisiana through its Department of Environmental Quality, several individuals, some of whom are present employees of the State of Louisiana, the Bayou South Gas Gathering Company, L.L.C., Martin Timber Company, Inc., and several trusts. Additionally on April 4, 2002, two plaintiffs filed a separate suit with identical allegations against the same parties in the same court. More recently, on January 6, 2003, two other plaintiffs filed a third suit of similar allegations against the Company, as well as other defendants, in Bossier Parish (26th Judicial District Court). The suits allege that, at some unspecified date prior to 1985, the defendants allowed or caused hydrocarbon or chemical contamination of the Wilcox Aquifer, which lies beneath property owned or leased by certain of the defendants and which is the sole or primary drinking water aquifer in the area. The primary source of the contamination is alleged by the plaintiffs to be a gas processing facility in Haughton, Bossier Parish, Louisiana known as the "Sligo Facility." This facility was purportedly used for gathering natural gas from surrounding wells, separating gasoline and hydrocarbons from the natural gas for marketing, and transmission of natural gas for distribution. This site was originally leased and operated by predecessors of REGT in the late 1940s and was operated until Arkansas Louisiana Gas Company ceased operations of the plant in the late 1970s. Beginning about 1985, the predecessors of certain Reliant Energy defendants engaged in a voluntary remediation of any subsurface contamination of the groundwater below the property they own or lease. This work has been done in conjunction with and under the direction of the Louisiana Department of Environmental Quality. The plaintiffs seek monetary damages for alleged damage to the aquifer underlying their property, unspecified alleged personal injuries, alleged fear of cancer, alleged property damage or diminution of value of their property, and, in addition, seek damages for trespass, punitive, and exemplary damages. The quantity of monetary damages sought is unspecified. As of December 31, 2002, the Company is unable to estimate the monetary damages, if any, that the plaintiffs may be awarded in these matters. Manufactured Gas Plant Sites. CERC and its predecessors operated manufactured gas plants (MGP) in the past. In Minnesota, remediation has been completed on two sites, other than ongoing monitoring and water treatment. There are five remaining sites in CERC's Minnesota service territory, two of which CERC believes were neither owned or operated by CERC, and for which CERC believes it has no liability. At March 31, 2003, CERC had accrued $19 million for remediation of the Minnesota sites. At March 31, 2003, the estimated range of possible remediation costs was $8 million to $44 million based on remediation continuing for 21

30 to 50 years. The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRP), if any, and the remediation methods used. CERC has utilized an environmental expense tracker mechanism in its rates in Minnesota to recover estimated costs in excess of insurance recovery. CERC has collected $12.2 million at March 31, 2003 to be used for future environmental remediation. CERC has received notices from the United States Environmental Protection Agency and others regarding its status as a PRP for other sites. Recently, the Company was informed that CERC has been named as a defendant in a third party complaint in the U.S. District Court for Maine under which contribution is sought for the cost to remediate a former MGP site in Bangor, Maine. The claim is based on the previous ownership of the site by a former affiliate of one of CERC's divisions. CERC has not been served with the complaint and presently is not aware of details regarding the site, the extent of any legal obligation to contribute to site remediation or the estimated cost of remediation. Based on current information, the Company has not been able to quantify a range of environmental expenditures for potential remediation expenditures with respect to other MGP sites. Mercury Contamination. The Company's pipeline and distribution operations have in the past employed elemental mercury in measuring and regulating equipment. It is possible that small amounts of mercury may have been spilled in the course of normal maintenance and replacement operations and that these spills may have contaminated the immediate area with elemental mercury. This type of contamination has been found by the Company at some sites in the past, and the Company has conducted remediation at these sites. It is possible that other contaminated sites may exist and that remediation costs may be incurred for these sites. Although the total amount of these costs cannot be known at this time, based on experience by the Company and that of others in the natural gas industry to date and on the current regulations regarding remediation of these sites, the Company believes that the costs of any remediation of these sites will not be material to the Company's financial condition, results of operations or cash flows. Other Environmental. From time to time the Company has received notices from regulatory authorities or others regarding its status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, the Company has been named as a defendant in litigation related to such sites and in recent years has been named, along with numerous others, as a defendant in several lawsuits filed by a large number of individuals who claim injury due to exposure to asbestos while working at sites along the Texas Gulf Coast. Most of these claimants have been workers who participated in construction of various industrial facilities, including power plants, and some of the claimants have worked at locations owned by the Company. The Company anticipates that additional claims like those received may be asserted in the future and intends to continue vigorously contesting claims which it does not consider to have merit. Although their ultimate outcome cannot be predicted at this time, the Company does not believe, based on its experience to date, that these matters, either individually or in the aggregate, will have a material adverse effect on the Company's financial condition, results of operations or cash flows. (c) Department of Transportation. In December 2002, Congress enacted the Pipeline Safety Improvement Act of 2002. This legislation applies to the Company's interstate pipelines as well as its intra-state pipelines and local distribution companies. The legislation imposes several requirements related to ensuring pipeline safety and integrity. It requires companies to assess the integrity of their pipeline transmission and distribution facilities in areas of high population concentration and further requires companies to perform remediation activities, in accordance with the requirements of the legislation, over a 10-year period. In January 2003, the U.S. Department of Transportation published a notice of proposed rulemaking to implement provisions of the legislation. The Department of Transportation is expected to issue final rules by the end of 2003. While the Company anticipates that increased capital and operating expenses will be required to comply with the requirements of the legislation, it will not be able to quantify the level of spending required until the Department of Transportation's final rules are issued. 22

(d) Other Proceedings. The Company is involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. Some of these proceedings involve substantial amounts. The Company's management regularly analyzes current information and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters. The Company's management believes that the disposition of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows. (e) Nuclear Insurance. Texas Genco and the other owners of the South Texas Project maintain nuclear property and nuclear liability insurance coverage as required by law and periodically review available limits and coverage for additional protection. The owners of the South Texas Project currently maintain $2.75 billion in property damage insurance coverage, which is above the legally required minimum, but is less than the total amount of insurance currently available for such losses. Pursuant to the Price Anderson Act, the maximum liability to the public of owners of nuclear power plants was $9.3 billion as of March 31, 2003. Owners are required under the Price Anderson Act to insure their liability for nuclear incidents and protective evacuations. Texas Genco and the other owners of the South Texas Project currently maintain the required nuclear liability insurance and participate in the industry retrospective rating plan. There can be no assurance that all potential losses or liabilities will be insurable, or that the amount of insurance will be sufficient to cover them. Any substantial losses not covered by insurance would have a material effect on the Company's financial condition, results of operations and cash flows. (f) Nuclear Decommissioning. Texas Genco contributed $2.9 million in 2002 to trusts established to fund its share of the decommissioning costs for the South Texas Project, and expects to contribute $2.9 million in 2003. There are various investment restrictions imposed upon Texas Genco by the Texas Utility Commission and the United States Nuclear Regulatory Commission (NRC) relating to Texas Genco's nuclear decommissioning trusts. Additionally, Texas Genco and CenterPoint Energy have each appointed two members to the Nuclear Decommissioning Trust Investment Committee which establishes the investment policy of the trusts and oversees the investment of the trusts' assets. The securities held by the trusts for decommissioning costs had an estimated fair value of $158 million as of March 31, 2003, of which approximately 48% were fixed-rate debt securities and the remaining 52% were equity securities. For a discussion of the accounting treatment for the securities held in the nuclear decommissioning trust, see Note 3(k) to the CenterPoint Energy Notes, which note is incorporated herein by reference. In July 1999, an outside consultant estimated Texas Genco's portion of decommissioning costs to be approximately $363 million. While the funding levels currently exceed minimum NRC requirements, no assurance can be given that the amounts held in trust will be adequate to cover the actual decommissioning costs of the South Texas Project. Such costs may vary because of changes in the assumed date of decommissioning and changes in regulatory requirements, technology and costs of labor, materials and equipment. Pursuant to the Texas electric restructuring law, costs associated with nuclear decommissioning that have not been recovered as of January 1, 2002, will continue to be subject to cost-of-service rate regulation and will be included in a charge to transmission and distribution customers. CenterPoint Energy is contractually obligated to indemnify Texas Genco from and against any obligations relating to the decommissioning not otherwise satisfied through collections by CenterPoint Houston. For information regarding the effect of the business separation plan on funding of the nuclear decommissioning trust fund, see Note 4(b) to the CenterPoint Energy Notes, which note is incorporated herein by reference. (g) "Price to Beat" Clawback Component. In connection with the implementation of the Texas electric restructuring law, the Texas Utility Commission has set a "price to beat" that retail electric providers affiliated or formerly affiliated with a former integrated utility must charge residential and small commercial customers within their affiliated electric utility's service area. The true-up provides for a clawback of "price to beat" in excess of the market price of electricity if 40% of the "price to beat" load is not served by a non-affiliated retail electric provider by January 1, 2004. Pursuant to the Texas electric 23

restructuring law and the master separation agreement between Reliant Energy and Reliant Resources, Reliant Resources is obligated to pay CenterPoint Houston for the clawback component of the true-up. The clawback may not exceed $150 times the number of customers served by the affiliated retail electric provider in the transmission and distribution utility's service territory, less the number of customers served by the affiliated retail electric provider outside the transmission and distribution utility's service territory, on January 1, 2004. (13) EARNINGS PER SHARE The following table presents the Company's basic and diluted earnings per share (EPS) calculation:

(14) REPORTABLE BUSINESS SEGMENTS The Company's determination of reportable business segments considers the strategic operating units under which the Company manages sales, allocates resources and assesses performance of various products and services to wholesale or retail customers in differing regulatory environments. The Company has identified the following reportable business segments: Electric Transmission & Distribution, Electric Generation, Natural Gas Distribution, Pipelines and Gathering and Other Operations. Reportable business segments presented herein do not include Wholesale Energy, European Energy, Retail Energy and related corporate costs as these business segments operated within Reliant Resources, which is presented as discontinued operations within these consolidated financial statements. Additionally, the Company's Latin America operations, which were previously reported in the Other Operations business segment, are presented as discontinued operations within these consolidated financial statements. Reportable business segments for all prior periods presented have been restated to conform to the 2003 presentation. The Company evaluates business segment performance on an earnings (loss) before interest expense, distribution on trust preferred securities, income taxes, minority interest, extraordinary item and cumulative effect of accounting change (EBIT) basis. EBIT, as defined, is shown because it is a measure the Company uses to evaluate the performance of its business segments, and the Company believes it is a measure of financial performance that may be used as a means to analyze and compare companies on the basis of operating performance. The Company expects that some analysts and investors will want to review EBIT when evaluating the Company. EBIT is not defined under GAAP, should not be considered in isolation or as a substitute for a measure of performance prepared in accordance with GAAP and is not indicative of operating income from operations as determined under GAAP. Additionally, the Company's computation of EBIT may not be comparable to other similarly titled measures computed by other companies, because all companies do not calculate it in the same fashion. Financial data for the Company's reportable business segments are as follows:

(15) GUARANTOR DISCLOSURES CenterPoint Energy has entered standard indemnification agreements with various surety companies to support the issuance of surety bonds on behalf of CenterPoint Energy and its subsidiaries. These indemnification agreements vary in duration to coincide with the term of the bonds issued. As of March 31, 2003, these agreements covered surety bonds in the aggregate amount of $14.1 million. In addition, CenterPoint Energy has provided $9.6 million in cash deposits to secure its indemnity to one surety company. (16) SUBSEQUENT EVENT During a routine refueling and maintenance outage in early April 2003, engineers found a small quantity of residue from reactor cooling water in the South Texas Project Unit 1 reactor containment building. No other residue was found in Unit 1 or in the plant's twin Unit 2 reactor when it was inspected during a refueling outage in the fall of 2002. Upon discovery of the residue, South Texas Project officials immediately reported their findings to the NRC. The South Texas Project's managers and engineers are conferring with industry experts to develop a corrective action plan. The NRC must approve any corrective action plan before it is implemented. Although Unit 1 was originally scheduled to be returned to service by May 2003, it will remain shut down until any necessary corrective action is completed. While the unit remains out of service, Texas Genco will meet its existing power sales obligations from other generating units and/or from purchases from third parties. A protracted outage at Unit 1 would adversely affect Texas Genco's operating results. Until inspections are completed and an acceptable corrective action plan has been developed, Texas Genco is unable to predict the extent of the economic impact of this outage and when the unit will be returned to service. Texas Genco does not expect Unit 1 will return to service before late summer of 2003. 26

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF CENTERPOINT ENERGY AND SUBSIDIARIES The following discussion and analysis should be read in combination with our Interim Financial Statements contained in this Form 10-Q. OVERVIEW We are a public utility holding company, created on August 31, 2002 as part of a corporate restructuring of Reliant Energy, Incorporated (Reliant Energy) in compliance with requirements of the Texas electric restructuring law. We are the successor to Reliant Energy for financial reporting purposes under the Securities Exchange Act of 1934. Our operating subsidiaries own and operate electric generation plants, electric transmission and distribution facilities, natural gas distribution facilities and natural gas pipelines. We are subject to regulation as a "registered holding company" under the Public Utility Holding Company Act of 1935 (1935 Act). Our indirect wholly owned subsidiaries include: o CenterPoint Energy Houston Electric, LLC (CenterPoint Houston), which engages in our electric transmission and distribution business in the Texas Gulf Coast area; and o CenterPoint Energy Resources Corp. (CERC Corp., and together with its subsidiaries, CERC), which owns and operates our local gas distribution companies, gas gathering systems and interstate pipelines. We also have an approximately 81% ownership interest in Texas Genco Holdings, Inc. (Texas Genco), which owns and operates our Texas generating plants formerly belonging to the integrated electric utility that was a part of Reliant Energy. We distributed the remaining 19% of the outstanding common stock of Texas Genco to our shareholders on January 6, 2003. At the time of Reliant Energy's corporate restructuring, it owned an 83% interest in Reliant Resources, Inc. (Reliant Resources), which conducts non-utility wholesale and retail energy operations primarily in North America and Western Europe. On September 30, 2002, we distributed that interest to our shareholders (the Reliant Resources Distribution). In this section we discuss our results from continuing operations on a consolidated basis and individually for each of our business segments. We also discuss our liquidity, capital resources and critical accounting policies. Our reportable business segments include the following: o Electric Transmission & Distribution; o Electric Generation; o Natural Gas Distribution; o Pipelines and Gathering; and o Other Operations. Effective with the full deregulation of sales of electric energy to retail customers in Texas beginning in January 2002, power generators and retail electric providers in Texas ceased to be subject to traditional cost-based regulation. Since that date, we have sold generation capacity, energy and ancillary services related to power generation at prices determined by the market. Our transmission and distribution services remain subject to rate regulation. Although our former retail sales business is no longer conducted by us, retail customers remained regulated customers of our former integrated electric utility, Reliant Energy HL&P, through the date of their first meter reading in 2002. Sales of electricity to retail customers in 2002 prior to this meter reading are reflected in the Electric Transmission & Distribution business segment. For business segment reporting information, please read Notes 1 and 14 to our Interim Financial Statements. 27

Subsequent to December 31, 2002, we sold our remaining Latin America operations. The Interim Financial Statements present these Latin America operations as discontinued operations in accordance with Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS No. 144). Accordingly, the Interim Financial Statements reflect these operations as discontinued operations for the three months ended March 31, 2002 and 2003. The Interim Financial Statements have been prepared to reflect the effect of the Reliant Resources Distribution on the CenterPoint Energy financial statements. The Interim Financial Statements present the Reliant Resources businesses (previously reported as Wholesale Energy, European Energy and Retail Energy business segments and related corporate costs) as discontinued operations, in accordance with SFAS No. 144. Accordingly, the Interim Financial Statements include the necessary reclassifications to reflect these operations as discontinued operations for the three months ended March 31, 2002. RECENT DEVELOPMENTS During a routine refueling and maintenance outage in early April 2003, engineers found a small quantity of residue from reactor cooling water in the South Texas Project Electric Generating Station (South Texas Project) Unit 1 reactor containment building. No other residue was found in Unit 1 or in the plant's twin Unit 2 reactor when it was inspected during a refueling outage in the fall of 2002. Upon discovery of the residue, South Texas Project officials immediately reported their findings to the Nuclear Regulatory Commission (NRC). The South Texas Project's managers and engineers are conferring with industry experts to develop a corrective action plan. The NRC must approve any corrective action plan before it is implemented. Although Unit 1 was originally scheduled to be returned to service by May 2003, it will remain shut down until any necessary corrective action is completed. While the unit remains out of service, Texas Genco will meet its existing power sales obligations from other generating units and/or from purchases from third parties. A protracted outage at Unit 1 would adversely affect Texas Genco's operating results. Until inspections are completed and an acceptable corrective action plan has been developed, Texas Genco is unable to predict the extent of the economic impact of this outage and when the unit will be returned to service. Texas Genco does not expect Unit 1 (Texas Genco's share is 385 MW) will return to service before late summer of 2003. In order to mitigate the financial impact of forced outages at its generating units, Texas Genco does not auction 750 MW of coal and lignite base-load capacity and 500 MW of gas-fired capacity. However, nuclear generation from the South Texas Project is Texas Genco's least expensive source of power because the cost of nuclear fuel is substantially less than that of coal, lignite or natural gas. Accordingly, while Unit 1 is shut down, Texas Genco will be required to satisfy capacity entitlements with significantly more expensive power and its ability to make opportunity sales and serve gas auction entitlements from South Texas Project production will be reduced. For example, Texas Genco's base-load capacity generally operates at an approximate energy cost of between $16/Mwh and $17/Mwh and gas fired capacity ranges between $55/Mwh and $60/Mwh based on current natural gas prices, while its nuclear generation capacity generally operates at an approximate energy cost of between $4/Mwh and $5/Mwh. 28

The following discussion of consolidated results of operations and results of operations by business segment is based on earnings from continuing operations before interest expense, distribution on trust preferred securities, income taxes, minority interest and cumulative effect of accounting change (EBIT). EBIT, as defined, is shown because it is a financial measure we use to evaluate the performance of our business segments and we believe it is a measure of financial performance that may be used as a means to analyze and compare companies on the basis of operating performance. We expect that some analysts and investors will want to review EBIT when evaluating our company. EBIT is not defined under accounting principles generally accepted in the United States (GAAP), should not be considered in isolation or as a substitute for a measure of performance prepared in accordance with GAAP and is not indicative of operating income from operations as determined under GAAP. Additionally, our computation of EBIT may not be comparable to other similarly titled measures computed by other companies, because all companies do not calculate it in the same fashion. We consider operating income to be a comparable measure under GAAP. We believe the difference between operating income and EBIT on both a consolidated and business segment basis is not material. We have provided a reconciliation of consolidated operating income to EBIT and EBIT to net income below as well as in the individual business segment discussion that follows. 29

THREE MONTHS ENDED MARCH 31, 2003 COMPARED TO THREE MONTHS ENDED MARCH 31, 2002 Income from Continuing Operations. We reported income from continuing operations before cumulative effect of accounting change of $81 million ($0.27 per diluted share) for the three months ended March 31, 2003 as compared to $145 million ($0.49 per diluted share) for the same period in 2002. The decrease in income from continuing operations of $64 million was primarily due to the following: o a $106 million increase in interest expense due to higher borrowing costs and increased debt levels; and o a $45 million decrease in EBIT from our Electric Transmission & Distribution business segment. The above items were partially offset by: o a $35 million increase in EBIT from our Electric Generation business segment; o a $24 million increase in EBIT from our Natural Gas Distribution business segment; and o a $27 million decrease in income tax expense. The derivation of the foregoing EBIT and its reconciliation to Operating Income is provided in the discussion of our business segments that follows. Income Tax Expense. During the three months ended March 31, 2003 and 2002, our effective tax rates were 33.2% and 31.9%, respectively. The increase in the effective tax rate for the first quarter of 2003 compared to the first quarter of 2002 was primarily the result of an increase in state taxes and a decrease in benefits related to the employee stock ownership plan, offset by a decrease in pretax income which amplified the effect of the permanent items on our effective tax rate. Cumulative Effect of Accounting Change. In connection with the adoption of SFAS No. 143, "Accounting for Asset Retirement Obligations" (SFAS No. 143), we have completed an assessment of the applicability and implications of SFAS No. 143. As a result of the assessment, we have identified retirement obligations for nuclear decommissioning at the South Texas Project and for lignite mine operations at the Jewett mine supplying the Limestone electric generation facility. The net difference between the amounts determined under SFAS No. 143 and the previous method of accounting for estimated mine reclamation costs was $37 million and has been 30

recorded as a cumulative effect of accounting change. Upon adoption of SFAS No. 143, we reversed $115 million of previously recognized removal costs with respect to our non-rate regulated businesses as a cumulative effect of accounting change. The total cumulative effect of accounting change from adoption of SFAS No, 143 was $152 million. Excluded from the $80 million after-tax cumulative effect of accounting change recorded for the three months ended March 31, 2003, is minority interest of $19 million related to the Texas Genco stock not owned by CenterPoint Energy. For additional discussion of the adoption of SFAS No. 143, please read Note 3 to our Interim Financial Statements. EARNINGS BEFORE INTEREST AND INCOME TAXES BY BUSINESS SEGMENT The following table presents EBIT for each of our business segments for the three months ended March 31, 2002 and 2003. Some amounts from the previous year have been reclassified to conform to the 2003 presentation of the financial statements. These reclassifications do no affect consolidated net income.

The following tables provide summary data, including EBIT, of our Electric Transmission & Distribution business segment for the three months ended March 31, 2002 and 2003:

Our Electric Transmission & Distribution business segment reported EBIT of $214 million for the three months ended March 31, 2003, consisting of $82 million for the regulated electric transmission & distribution utility and non-cash EBIT of $132 million associated with generation-related regulatory assets, or Excess Cost Over Market (ECOM), as described below. For the three months ended March 31, 2002, EBIT was $259 million, consisting of $104 million for the regulated electric transmission & distribution utility, non-cash EBIT of $141 associated with ECOM, and $14 million related to the transition to the deregulated electric market. Although our former retail sales business is no longer conducted by us, retail customers remained regulated customers of the regulated utility through the date of their first meter reading in 2002. The purchased power costs of $60 million for the three months ended March 31, 2002 relate to operation of the regulated utility during this transition period. The regulated electric transmission & distribution utility, excluding ECOM and transition related-EBIT, continues to benefit from solid customer growth. Reduced revenues from industrial customers ($9 million) and higher employee benefit and insurance costs ($8 million) more than offset increased revenues from the addition of over 50,000 metered customers since March 2002 ($8 million). Under the Texas electric restructuring law, a regulated utility may recover, in its 2004 stranded cost true-up proceeding, any difference between market prices received through the state mandated auctions and the Texas Utility Commission's earlier estimates of those market prices. During 2002 and 2003, this difference, referred to as ECOM, produces non-cash EBIT and is recorded as a regulatory asset. The reduction in ECOM of $9 million from 2002 to 2003 resulted from an increase in capacity auction prices at Texas Genco. Operation and maintenance expense decreased $8 million for the three months ended March 31, 2003 as compared to the same period in 2002. The decrease was primarily due to a reduction in bad debt expense of $17 million related to the 2002 transition period (bundled) revenues ($14 million) and the termination of a factoring program ($3 million). This decrease in bad debt expense was partially offset by increased employee benefit expenses primarily due to increased pension costs ($5 million) and increased insurance expenses ($3 million). 32

Depreciation and amortization expense increased $2 million for the three months ended March 31, 2003 as compared to the same period in 2002 primarily due to increases in plant in service ($4 million) partially offset by decreased amortization on securitized assets ($2 million). Taxes other than income taxes decreased $6 million for the three months ended March 31, 2003 as compared to the same period in 2002 primarily due to gross receipts tax associated with transition period revenue in the first quarter of 2002. ELECTRIC GENERATION For information regarding factors that may affect the future results of operations of our Electric Generation business segment, please read "Business -- Risk Factors -- Risk Factors Affecting the Results of Our Electric Generation Business" in Item 1 of the CenterPoint Energy Form 10-K, which is incorporated herein by reference. The following tables provide summary data, including Loss Before Interest and Income Taxes, of our Electric Generation business segment for the three months ended March 31, 2002 and 2003:

THREE MONTHS ENDED MARCH 31, ------------------------------ 2002 2003 ------------ ------------ (IN MILLIONS) Operating Revenues: Energy Revenues ........................... $ 241 $ 224 Capacity and Other Revenues ............... 85 135 ------------ ------------ Total Operating Revenues ................ 326 359 ------------ ------------ Operating Expenses: Fuel and Purchased Power .................. 229 220 Operation and Maintenance ................. 96 106 Depreciation and Amortization ............. 40 39 Taxes Other than Income Taxes ............. 13 11 ------------ ------------ Total Operating Expenses ................ 378 376 ------------ ------------ Operating Income ............................

Our Electric Generation business segment's loss before interest and income taxes for the three months ended March 31, 2003 was $17 million compared to a loss before interest and income taxes of $52 million for the same period in 2002. The improvement is primarily attributable to increased gross margins as a result of higher capacity auction prices driven by higher gas prices, partially offset by increased operation and maintenance expenses due to unplanned forced outages in the first quarter of 2003 and higher property insurance expense. The first quarter is typically Texas Genco's lowest performing quarter due to seasonal revenue effects and the scheduling of planned maintenance on its generating units. South Texas Project Unit 2 was taken out of service in December 2002 as a result of non-safety related mechanical failures and was returned to service on March 14, 2003. The added cost of replacement energy negatively impacted gross margin by approximately $23 million for the first quarter of 2003. Operation and maintenance expense increased $10 million for the three months ended March 31, 2003 as compared to the same period in 2002 primarily due to the Unit 2 outage discussed above ($4 million), a scheduled re-fueling outage on Unit 1 ($2 million) and higher property insurance expense ($1 million). Taxes other than income taxes decreased $2 million for the three months ended March 31, 2003 as compared to the same period in 2002. This decrease was attributable to a reduction in property taxes. 33

NATURAL GAS DISTRIBUTION Our Natural Gas Distribution business segment's operations consist of intrastate natural gas sales to, and natural gas transportation for residential, commercial and industrial customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma and Texas. This business segment's operations also include non-rate regulated natural gas sales to and transportation services for commercial and industrial customers in the six states listed above as well as several other Midwestern states. For information regarding factors that may affect the future results of operations of our Natural Gas Distribution business segment, please read "Business -- Risk Factors -- Risk Factors Affecting the Results of Our Natural Gas Distribution and Pipelines and Gathering Businesses" in Item 1 of the CenterPoint Energy Form 10-K, which is incorporated herein by reference. The following table provides summary data, including EBIT, of our Natural Gas Distribution business segment for the three months ended March 31, 2002 and 2003:

Our Natural Gas Distribution business segment's EBIT increased $24 million for the three months ended March 31, 2003 as compared to the same period in 2002. Operating margins (revenues less fuel costs) for the three months ended March 31, 2003 were $56 million higher than in the same period in 2002 primarily because of: o continued customer growth ($4 million); o higher revenues from rate increases late in 2002 ($11 million); o colder weather ($7 million); o improved margins from our unregulated commercial and industrial sales ($9 million); and o franchise fees billed to customers ($11 million). These increases were partially offset by increased operating expenses as discussed below. Operations and maintenance expense increased $16 million for the three months ended March 31, 2003 as compared to the same period in 2002. The increase in operations and maintenance expense was primarily due to: o certain costs being included in operating expense subsequent to the amendment of a receivables facility in November 2002 as compared with being included in interest expense in the prior year ($4 million); 34

o increased bad debt expense primarily due to colder weather and higher gas prices ($4 million); and o higher employee benefit expenses primarily due to increased pension costs ($4 million). Depreciation and amortization expense increased approximately $3 million for the three months ended March 31, 2003 as compared to the same period in 2002 primarily as a result of increases in plant in service. Taxes other than income taxes increased $13 million for the three months ended March 31, 2003 as compared to the same period in 2002, primarily due to increased franchise fees resulting from higher revenues ($11 million). PIPELINES AND GATHERING Our Pipelines and Gathering business segment operates two interstate natural gas pipelines and provides gathering and pipeline services. For information regarding factors that may affect the future results of operations of our Pipelines and Gathering business segment, please read "Business -- Risk Factors -- Risk Factors Affecting the Results of Our Natural Gas Distribution and Pipelines and Gathering Businesses" in Item 1 of the CenterPoint Energy Form 10-K, which is incorporated herein by reference. The following table provides summary data, including EBIT, of our Pipelines and Gathering business segment for the three months ended March 31, 2002 and 2003:

- ------------- (1) Elimination of volumes both transported and sold. Our Pipelines and Gathering business segment's EBIT for the three months ended March 31, 2003 compared to the same period in 2002, increased $7 million. Operating margins were $3 million higher for the three months ended March 31, 2003 than in the same period in 2002 primarily due to increased margins resulting from higher gas and liquid commodity prices ($9 million), which were partially offset by reduced project related revenues ($5 million). Operation and maintenance expenses decreased $4 million for the three months ended March 31, 2003 compared to the same period in 2002 primarily due to a decrease in project related costs ($5 million), partially offset by an increase in employee benefit expenses primarily due to increased pension costs ($1 million). 35

Depreciation and amortization expense increased $1 million for the three months ended March 31, 2003, as compared to the same period in 2002 primarily as a result of increases in plant in service. OTHER OPERATIONS Our Other Operations business segment includes district cooling operations in the central business district in downtown Houston, energy management services and other corporate operations which support all of our business operations. The following table shows EBIT of our Other Operations business segment for the three months ended March 31, 2002 and 2003:

THREE MONTHS ENDED MARCH 31, ------------------------------ 2002 2003 ------------ ------------ (IN MILLIONS) Operating Revenues .......................... $ 9 $ 11 Operating Expenses .......................... 4 12 ------------ ------------ Operating Income ............................ 5 (1) Other Expense, net ......................... (13) (4) ------------ ------------ Loss Before Interest and Income Taxes ....... $ (8) $ (5) ============ ============
Our Other Operations business segment's loss before interest and income taxes decreased by $3 million for the three months ended March 31, 2003 compared to the same period in 2002. The decline for the three months was primarily due to a net loss of $6 million in 2003 as compared to a net loss of $14 million in 2002 on our AOL Time Warner investment and related indexed debt securities, partially offset by an increase in unallocated corporate costs and corporate accruals. DISCONTINUED OPERATIONS In February 2003, we sold our interest in Argener, a cogeneration facility in Argentina, for $23.1 million. The carrying value of this investment was approximately $11 million as of December 31, 2002. We recorded an after-tax gain of $7 million from the sale of Argener in the first quarter of 2003. We have completed our strategy of exiting Latin America. The Interim Financial Statements present these Latin America operations as discontinued operations in accordance with SFAS No. 144 for the three months ended March 31, 2002 and 2003. On September 30, 2002, we distributed to our shareholders on a pro rata basis all of the shares of Reliant Resources common stock owned by us. The Interim Financial Statements have been prepared to reflect the effect of the Reliant Resources Distribution as described above on our Interim Financial Statements. The Interim Financial Statements present the Reliant Resources businesses (Wholesale Energy, European Energy, Retail Energy and related corporate costs) as discontinued operations for the three months ended March 31, 2002. We recorded an after-tax loss from discontinued operations of $113 million for the three months ended March 31, 2002 related to the operations of Reliant Resources. CERTAIN FACTORS AFFECTING FUTURE EARNINGS For information on other developments, factors and trends that may have an impact on our future earnings, please read "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Certain Factors Affecting Future Earnings" in Exhibit 99.1 to our Current Report on Form 8-K dated May 12, 2003 (May 12 Form 8-K), which is incorporated herein by reference. In addition to the factors incorporated by reference from the May 12 Form 8-K, increased borrowing costs and increased pension expense are expected to negatively impact our earnings in 2003.

LIQUIDITY AND CAPITAL RESOURCES HISTORICAL CASH FLOWS The following table summarizes the net cash provided by (used in) operating, investing and financing activities for the three months ended March 31, 2002 and 2003:

THREE MONTHS ENDED MARCH 31, --------------------------------- 2002 2003 -------------- -------------- (IN MILLIONS) Cash provided by (used in): Operating activities..................................................... $ (188) $ 8 Investing activities..................................................... (192) (147) Financing activities..................................................... 386 115
Net cash provided by operating activities during the three months ended March 31, 2003 increased $196 million compared to the same period in 2002 primarily due to increased accounts payable, partially offset by decreased accrued taxes and interest and increases in net regulatory assets. Net cash used in investing activities decreased $45 million during the three months ended March 31, 2003 compared to the same period in 2002 primarily due to lower capital expenditures in 2003. Net cash provided by financing activities decreased $271 million during the three months ended March 31, 2003 compared to the same period in 2002 primarily due a decrease in short-term borrowings, partially offset by an increase in net proceeds from long-term debt. FUTURE SOURCES AND USES OF CASH FLOWS Long-Term Debt. Our long-term debt consists of our obligations and obligations of our subsidiaries, including transition bonds issued by an indirect wholly owned subsidiary (transition bonds). On February 28, 2003, we reached agreement with a syndicate of banks on a second amendment to our $3.85 billion bank facility (Second Amendment). Under the Second Amendment, the maturity date of the bank facility was extended from October 2003 to June 30, 2005, and the $1.2 billion in mandatory prepayments that would have been required in 2003 (including $600 million due on February 28, 2003) were eliminated. At the time of the Second Amendment, the facility consisted of a $2.35 billion term loan and a $1.5 billion revolver. In March 2003, a $50 million repayment of the term loan reduced the term loan to $2.30 billion. The revolver was fully utilized on March 31, 2003. Borrowings bear interest based on the London interbank offered rate (LIBOR) under a pricing grid tied to our credit rating. At our current credit ratings, the pricing for loans remains the same. The drawn cost at our current ratings is LIBOR plus 450 basis points. We have agreed to pay the banks an extension fee of 75 basis points on the amounts outstanding under the bank facility on October 9, 2003. We also paid $41 million in fees that were due on February 28, 2003, along with $20 million in fees that had been due on June 30, 2003. In addition, the interest rate will be increased by 25 basis points beginning May 28, 2003 if we do not grant the banks a security interest in our 81% stock ownership of Texas Genco. Granting the security interest in the stock of Texas Genco requires approval from the Securities and Exchange Commission (SEC) under the 1935 Act, which is currently being sought. That security interest would be released at the time of a sale of Texas Genco, which may occur as early as 2004. Proceeds from any sale will be used to reduce the bank facility. Also under the Second Amendment, on or before May 28, 2003, we agreed to grant to the banks warrants to purchase up to 10%, on a fully diluted basis, of our common stock at a price equal to the greater of $6.56 per share or 110% of the closing price on the New York Stock Exchange on the date the warrants are issued. The warrants would not be exercisable for a year after issuance but would remain outstanding for four years; provided, that if we reduce the term loans owed under the bank facility during 2003 by specified amounts, the warrants will be extinguished. To the extent that we reduce the term loans owed under the bank facility by up to $400 million on or before May 28, 2003, up to half of the warrants will be extinguished on a basis proportionate to the reduction in the credit facility. To the extent such warrants are not extinguished on or before May 28, 2003, they will vest and become exercisable in accordance with their terms. At 37

March 31, 2003, we had reduced the term loans owed under the bank facility by $50 million. Whether or not we are able to extinguish warrants on or before May 28, 2003, the remaining 50% of the warrants will be extinguished, again on a proportionate basis, if we reduce the term loans owed under the bank facility by up to $400 million by the end of 2003. We plan to eliminate the warrants entirely before they vest by accessing the capital markets to fund the total payments of $800 million during 2003; however there can be no assurance that we will be able to extinguish the warrants or to do so on favorable terms. The warrants and the underlying common stock would be registered with the SEC and could be exercised either through the payment of the purchase price or on a "cashless" basis under which we would issue a number of shares based upon the difference between the then-current market price and the warrant exercise price. Issuance of the warrants is also subject to obtaining SEC approval under the 1935 Act, which is currently being sought. If that approval is not obtained on or before May 28, 2003, we will provide the banks equivalent cash compensation over the term that our warrants would have been exercisable to the extent they are not otherwise extinguished. In the Second Amendment, we also agreed that our quarterly common stock dividend will not exceed $0.10 per share. If we have not reduced the bank facility by a total of at least $400 million by the end of 2003, of which at least $200 million has come from the issuance of capital stock or securities linked to capital stock (such as convertible debt), the maximum dividend payable during 2004 and for the balance of the term of the facility is subject to an additional test. Under that test the maximum permitted quarterly dividend will be the lesser of (i) $0.10 per share or (ii) 12.5% of our net income per share for the 12 months ended on the last day of the previous quarter. The Second Amendment provides that proceeds from capital stock or indebtedness issued or incurred by us must be applied (subject to a $200 million basket for CERC and another $250 million basket for borrowings by us, certain permitted refinancings of existing debt and other limited exceptions) to repay bank loans and permanently reduce the bank facility. Similarly, cash proceeds from the sale of assets of more than $30 million or, if less, a group of sales aggregating more than $100 million, must be applied to repay bank loans and reduce the bank facility, except that proceeds of up to $120 million can be reinvested in our businesses. On March 18, 2003, CenterPoint Houston issued $762.3 million aggregate principal amount of general mortgage bonds composed of $450 million principal amount of 10-year bonds with an interest rate of 5.7% and $312.3 million principal amount of 30-year bonds with an interest rate of 6.95%. Proceeds were used to repay $150 million aggregate principal amount of medium-term notes maturing on April 21, 2003, to redeem approximately $312.3 million aggregate principal amount of CenterPoint Houston's first mortgage bonds and to repay $279 million of a $537 million intercompany note payable to CenterPoint Energy by CenterPoint Houston. Proceeds from the note repayment were ultimately used to repay borrowings under our $3.85 billion credit facility and to permanently reduce the term loan component of the credit facility by $50 million. On March 25 and April 14, 2003, CERC issued $650 million and $112 million, respectively, aggregate principal amount of 7.875% senior unsecured notes due in 2013. A portion of the proceeds were used to refinance $360 million aggregate principal amount of CERC's 6 3/8% Term Enhanced ReMarketable Securities (TERM Notes) and to pay costs associated with the refinancing. Proceeds were also used to repay borrowings under CERC's $350 million revolving credit facility prior to its expiration on March 31, 2003. The remaining $140 million aggregate principal amount of TERM Notes are due to be refinanced or remarketed in November 2003. On April 9, 2003, we remarketed $175 million aggregate principal amount of pollution control bonds that we had owned since the fourth quarter of 2002. Remarketed bonds maturing in 2029 have a principal amount of $75 million and an interest rate of 8%. Remarketed bonds maturing in 2018 have a principal amount of $100 million and an interest rate of 7.75%. Proceeds from the remarketing were used to repay bank debt. We are obligated to make payments sufficient to service the pollution control bonds. In addition to the $140 million of TERM Notes, remaining maturities in 2003 include $16.6 million principal amount of pollution control bonds and $12 million of expected maturities of transition bonds which are discussed below. We have $840 million of outstanding 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (ZENS) that may be exchanged for cash at any time. Holders of ZENS submitted for exchange are entitled to receive a cash payment equal to 95% of the market value of the reference shares of AOL Time Warner common stock (AOL TW Common). There are 1.5 reference shares of AOL TW Common for each of the 17.2 million ZENS units originally issued (of which approximately 16% were exchanged for cash of approximately $45 million in 2002). The exchange 38

market value is calculated using the average closing price per share of AOL TW Common on the New York Stock Exchange on one or more trading days following the notice date for the exchange. One of our subsidiaries owns the reference shares of AOL TW Common and generally liquidates such holdings to the extent of ZENS exchanged. Cash proceeds from such liquidations are used to fund ZENS exchanged for cash. Although proceeds from the sale of AOL TW Common offset the cash paid on exchanges, ZENS exchanges result in a cash outflow because deferred tax liabilities related to the ZENS and AOL TW Common become current tax obligations when ZENS are exchanged and AOL TW Common is sold. There have been no exchanges in 2003. CenterPoint Houston has outstanding approximately $699 million aggregate principal amount of first mortgage bonds and approximately $2.6 billion aggregate principal amount of general mortgage bonds, of which approximately $924 million combined aggregate principal amount of first mortgage bonds and general mortgage bonds collateralizes debt of CenterPoint Energy. The general mortgage bonds are issued under the General Mortgage Indenture dated as of October 10, 2002. The lien of the general mortgage indenture is junior to that of the Mortgage, pursuant to which the first mortgage bonds are issued. The aggregate amount of additional general mortgage bonds and first mortgage bonds that could be issued is approximately $600 million based on estimates of the value of property encumbered by the general mortgage, the cost of such property and the 70% bonding ratio contained in the general mortgage. As a result of contractual limitations expiring in November 2005, the aggregate amount of first mortgage and general mortgage bonds cannot be increased above current levels. One of our indirect finance subsidiaries, CenterPoint Energy Transition Bond Company, LLC, has $729 million aggregate principal amount of outstanding transition bonds that were issued in 2001 in accordance with the Texas electric restructuring law. Classes of the transition bonds have final maturity dates of September 15, 2007, September 15, 2009, September 15, 2011 and September 15, 2015 and bear interest at rates of 3.84%, 4.76%, 5.16% and 5.63%, respectively. The transition bonds are secured by "transition property," as defined in the Texas electric restructuring law, which includes the irrevocable right to recover, through non-bypassable transition charges payable by retail electric customers, qualified costs provided in the Texas electric restructuring law. The transition bonds are reported as our long-term debt, although the holders of the transition bonds have no recourse to any of our assets or revenues, and our creditors have no recourse to any assets or revenues (including, without limitation, the transition charges) of the transition bond company. CenterPoint Houston has no payment obligations with respect to the transition bonds except to remit collections of transition charges as set forth in a servicing agreement between CenterPoint Houston and the transition bond company and in an intercreditor agreement among CenterPoint Houston, our indirect transition bond subsidiary and other parties. Short-Term Debt and Receivables Facility. CERC's revolver and receivables facility are scheduled to terminate on the dates indicated. Please read Note 9(a) to our Interim Financial Statements regarding CERC's receivables facility.

Revolver 200 -- March 23, 2004 ------------ ------------- Total $ 350 $ 150 ============ =============
On February 28, 2003, our $3.85 billion bank facility was amended and extended to June 2005 as discussed above in " -- Long-Term Debt." Loans under this facility are recorded as long-term debt in the Consolidated Balance Sheets at both December 31, 2002 and March 31, 2003. On March 25, 2003, CERC obtained a $200 million revolving credit facility that terminates on March 23, 2004. Rates for borrowings under this facility, including the facility fee, are LIBOR plus 250 basis points based on current credit ratings and the applicable pricing grid. On March 31, 2003, we had $279 million of temporary investments. Refunds to CenterPoint Houston Customers. An order issued by the Texas Utility Commission on October 3, 2001 established the transmission and distribution rates that became effective in January 2002. The Texas Utility Commission determined that CenterPoint Houston had overmitigated its stranded costs by redirecting transmission 39

and distribution depreciation and by accelerating depreciation of generation assets (an amount equal to earnings above a stated overall rate of return on rate base that was used to recover our investment in generation assets) as provided under the 1998 transition plan and the Texas electric restructuring law. In this final order, CenterPoint Houston is required to reverse the amount of redirected depreciation and accelerated depreciation taken for regulatory purposes as allowed under the transition plan and the Texas electric restructuring law. Per the October 3, 2001 order, CenterPoint Houston recorded a regulatory liability to reflect the prospective refund of the accelerated depreciation. CenterPoint Houston began refunding excess mitigation credits with the January 2002 unbundled bills, to be refunded over a seven-year period. The annual refund of excess earnings is approximately $237 million. Under the Texas electric restructuring law, a final determination of these stranded costs will occur in 2004. Cash Requirements in 2003. Our liquidity and capital requirements are affected primarily by our results of operations, capital expenditures, debt service requirements, and working capital needs. On April 30, 2003 we had no temporary investments and unutilized capacity of $657 million under our bank facilities and receivables facility.

UNUTILIZED AMOUNT AS OF BORROWER/SELLER TYPE OF FACILITY AMOUNT OF FACILITY APRIL 30, 2003 --------------- ---------------- ------------------ ----------------- (IN MILLIONS) CenterPoint Energy Revolver/term loan $3,800 $ 427 CERC Corp. Revolver 200 200 CERC Receivables 150 30 ------ ------ Total $4,150 $ 657 ====== =====
Our principal remaining cash requirements during 2003 include the following: o approximately $543 million of capital expenditures; o an estimated $185 million which we are obligated to return to customers as a result of the Texas Utility Commission's findings of over-mitigation of stranded costs; o remarketing or refinancing of $140 million of CERC Corp. debt, plus the possible payment of option termination costs, which will be determined at the time of remarketing or refinancing (estimated to be $18.2 million as of March 31, 2003) as discussed in "Quantitative and Qualitative Disclosures About Market Risk -- Interest Rate Risk" in Item 3 of this report; o dividend payments on CenterPoint Energy common stock; and o $29 million of maturing long-term debt. We expect to meet our capital requirements through cash flows from operations, short-term borrowings and proceeds from debt and/or equity offerings. We believe that our current liquidity, along with anticipated cash flows from operations and proceeds from short-term borrowings, including the renewal, extension or replacement of existing bank facilities, and anticipated sales of securities in the capital markets will be sufficient to meet our cash needs. However, the mandatory prepayments required under our $3.85 billion bank facility and disruptions in our ability to access the capital markets on a timely basis could adversely affect our liquidity. Limits on our ability to issue secured debt, as described in this report, may adversely affect our ability to issue debt securities. Please read "Business -- Risk Factors -- Risk Factors Associated with Financial Condition and Other Risks -- If we are unable to arrange future financings on acceptable terms, our ability to fund future capital expenditures and refinance existing indebtedness could be limited" in Item 1 of the CenterPoint Energy 10-K, which is incorporated herein by reference. At March 31, 2003, CenterPoint Energy had a shelf registration statement for 15 million shares of common stock and CERC Corp. had a shelf registration statement covering $50 million of debt securities. The amount of any debt security or any security having equity characteristics that we can issue, whether registered or unregistered, or whether debt is secured or unsecured, is expected to be affected by the market's perception of our creditworthiness, general market conditions and factors affecting our industry. Proceeds from the sales of securities are expected to be used primarily to refinance debt. 40

Principal Factors Affecting Cash Requirements in 2004 and 2005. We anticipate selling our 81% ownership interest in Texas Genco in 2004. Should Reliant Resources decline to exercise its option to purchase our interest in Texas Genco, we will explore other alternatives to monetize Texas Genco's assets, including possible sale of our ownership interest in Texas Genco or of its individual generating assets, which may significantly affect the timing of any cash proceeds. Proceeds from that sale, plus proceeds from the securitization in 2004 or 2005 of stranded costs related to generating assets of Texas Genco and generation related regulatory assets, are expected to aggregate in excess of $5 billion. We expect to issue securitization bonds in 2004 or 2005 to monetize and recover the balance of stranded costs relating to electric generation assets and other qualified costs as determined in the 2004 True-Up Proceeding. The issuance will be done pursuant to a financing order to be issued by the Texas Utility Commission. As with the debt of our existing transition bond company, payments on these new securitization bonds would also be made from funds obtained through non-bypassable charges assessed to retail electric customers required to take delivery service from CenterPoint Houston. The holders of the securitization bonds would not have recourse to any of our assets or revenues, and our creditors would not have recourse to any assets or revenues of the entity issuing the securitization bonds. All or a portion of the proceeds from the issuance of securitization bonds remaining after repayment of CenterPoint Houston's $1.3 billion collateralized term loan are expected to be utilized to retire other existing debt. Impact on Liquidity of a Downgrade in Credit Ratings. As of May 1, 2003, Moody's Investors Service, Inc. (Moody's), Standard & Poor's Ratings Services, a division of The McGraw Hill Companies (S&P), and Fitch, Inc. (Fitch) had assigned the following credit ratings to senior debt of CenterPoint Energy and certain subsidiaries:

MOODY'S S&P FITCH ------------------- ------------------- ------------------ COMPANY/INSTRUMENT RATING OUTLOOK(1) RATING OUTLOOK(2) RATING OUTLOOK(3) ------------------- -------- ---------- ------- ---------- ------ ---------- CenterPoint Energy Senior Unsecured Debt.................................... Ba1 Negative BBB- Stable BBB- Stable CenterPoint Houston Senior Secured Debt (First Mortgage Bonds).................. Baa2 Stable BBB Stable BBB+ Stable CERC Corp. Senior Debt..................... Ba1 Negative BBB Stable BBB Stable
- ---------- (1) A "negative" outlook from Moody's reflects concerns over the next 12 to 18 months which will either lead to a review for a potential downgrade or a return to a stable outlook. A "stable outlook" from Moody's indicates that Moody's does not expect to put the rating on review for an upgrade or downgrade within 18 months from when the outlook was assigned or last affirmed. (2) A "stable" outlook from S&P indicates that the rating is not likely to change over the intermediate to longer term. (3) A "stable" outlook from Fitch indicates the direction a rating is likely to move over a one- to two-year period. We cannot assure you that these ratings will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency. We note that these credit ratings are not recommendations to buy, sell or hold our securities and may be revised or withdrawn at any time by the rating agency. Each rating should be evaluated independently of any other rating. Any future reduction or withdrawal of one or more of our credit ratings could have a material adverse impact on our ability to obtain short- and long-term financing, the cost of such financings and the execution of our commercial strategies. A decline in credit ratings would increase facility fees and borrowing costs under our existing bank credit facilities. A decline in credit ratings would also increase the interest rate on long-term debt to be issued in the capital markets and would negatively impact our ability to complete capital market transactions. Our bank facilities contain "material adverse change" clauses that could impact our ability to make new borrowings under these facilities. The "material adverse change" clauses in our bank facilities generally relate to an event, development or circumstance that has or would reasonably be expected to have a material adverse effect on (a) the business, financial condition or operations of the borrower and its subsidiaries taken as a whole, or (b) the 41

legality, validity or enforceability of the loan documents. The $150 million receivables facility of CERC requires the maintenance of credit ratings of at least BB from S&P and Ba2 from Moody's. Receivables would cease to be sold in the event a credit rating fell below the threshold. Each ZENS note is exchangeable at the holder's option at any time for an amount of cash equal to 95% of the market value of the reference shares of AOL TW Common attributable to each ZENS note. If our creditworthiness were to drop such that ZENS note holders thought our liquidity was adversely affected or the market for the ZENS notes were to become illiquid, some ZENS holders might decide to exchange their ZENS for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the AOL TW Common that we own or from other sources. We own shares of AOL TW Common equal to 100% of the reference shares used to calculate our obligation to the holders of the ZENS notes. ZENS exchanges result in a cash outflow because deferred tax liabilities related to the ZENS and AOL TW Common become current tax obligations when ZENS are exchanged and AOL TW Common is sold. CenterPoint Energy Gas Resources Corp., a wholly owned subsidiary of CERC Corp., provides comprehensive natural gas sales and services to industrial and commercial customers who are primarily located within or near the territories served by our pipelines and distribution subsidiaries. In order to hedge its exposure to natural gas prices, CenterPoint Energy Gas Resources Corp. has agreements with provisions standard for the industry that establish credit thresholds and require a party to provide additional collateral on two business days' notice when that party's rating or the rating of a credit support provider for that party (CERC Corp. in this case) falls below those levels. As of May 1, 2003, the senior unsecured debt of CERC Corp. was rated BBB by S&P and Ba1 by Moody's. Based on these ratings, we estimate that unsecured credit limits extended to CenterPoint Energy Gas Resources Corp. by counterparties could aggregate $39 million; however, utilized credit capacity is significantly lower. Cross Defaults. Under our bank facility, a payment default by us or any of our significant subsidiaries on any indebtedness exceeding $50 million will cause a default. A default by CenterPoint Energy would not trigger a default under our subsidiaries' debt instruments. Pension Plan. As discussed in Note 11 of the notes to the consolidated financial statements in the May 12 Form 8-K (CenterPoint Energy Notes), which is incorporated herein by reference, we maintain a non-contributory pension plan covering substantially all employees. At December 31, 2002, the projected benefit obligation exceeded the market value of plan assets by $496 million. We are not required and do not anticipate making any contributions to our pension plans prior to 2004. Changes in interest rates and the market values of the securities held by the plans during 2003 could materially, positively or negatively, change our underfunded status and affect the level of pension expense and required contributions in 2004 and beyond. For example, every .5% difference in our actual 2003 asset returns versus our assumed 9% long-term asset return rate would increase or decrease the underfunded status of our plans by approximately $5 million and our 2004 pension expense by approximately $1 million. Similarly, a .5% change in the discount rate used to value pension liabilities at December 31, 2003, could increase or decrease the underfunded status of our plans by approximately $100 million and 2004 pension expense by approximately $14 million. Actual investment returns and changes in the discount rate during 2003 will have no effect on our 2003 pension expense. Additionally, we expect that a separate pension plan will be established for Texas Genco in 2004. Texas Genco would receive an allocation of assets from the CenterPoint Energy pension plan pursuant to rules and regulations under the Employee Retirement Income Security Act of 1974 and record its pension obligations in accordance with SFAS 87, "Employer's Accounting for Pensions". It is anticipated that a plan established for Texas Genco would be underfunded and that such underfunding could be significant. Changes in interest rates and the market values of the securities held by the CenterPoint Energy pension plan during 2003 could materially, positively or negatively, change the funding status of a plan established for Texas Genco. Other Factors that Could Affect Cash Requirements. In addition to the above factors, our liquidity and capital resources could be affected by: o the need to provide cash collateral in connection with certain contracts; o acceleration of payment dates on certain gas supply contracts under certain circumstances, as a result of increased gas prices and concentration of suppliers; 42

o increased costs related to the acquisition of gas for storage; o increases in interest expense in connection with debt refinancings; o various regulatory actions; and o the ability of Reliant Resources and its subsidiaries to satisfy their obligations as the principal customers of CenterPoint Houston and Texas Genco and in respect of its indemnity obligations to us. Money Pool. We have a "money pool" through which we and our participating subsidiaries can borrow or invest on a short-term basis. Funding needs are aggregated and external borrowing or investing is based on the net cash position. The money pool's net funding requirements are expected to be met with bank loans. The terms of the money pool are in accordance with requirements applicable to registered public utility holding companies under the 1935 Act. Capitalization. Factors affecting our capitalization include: o covenants and other provisions in our and our subsidiaries' bank facilities and other borrowing agreements; and o limitations imposed on us as a registered public utility holding company. The collateralized term loan of CenterPoint Houston limits CenterPoint Houston's debt, excluding transition bonds, as a percentage of its total capitalization to 68%. CERC Corp.'s bank facility and its receivables facility limit CERC's debt as a percentage of its total capitalization to 60% and contain an earnings before interest, taxes, depreciation and amortization (EBITDA) to interest covenant. CERC Corp.'s bank facility also contains a provision that could, under certain circumstances, limit the amount of dividends that could be paid by CERC Corp. Our $3.85 billion credit agreement limits dividend payments as described above, contains a debt to EBITDA covenant, an EBITDA to interest covenant and restrictions on the use of proceeds from debt issuances and asset sales. In connection with our registration as a public utility holding company under the 1935 Act, the SEC has placed the following limitations on our external debt: o the aggregate amount of CenterPoint Houston's external borrowings has been limited to $3.55 billion; o the aggregate amount of CERC Corp.'s external borrowings has been limited to $2.7 billion; and o the aggregate amount of Texas Genco's external borrowings has been limited to $500 million. Additionally, the SEC has placed limitations on our dividends and the dividends of our subsidiaries that require common equity as a percentage of total capitalization for CenterPoint Houston, CERC Corp. and Texas Genco to be at least 30% after the payment of such dividends. The order issued by the SEC that authorizes our financing program expires on June 30, 2003, and we must seek a new financing order before that date. Any new order may contain restrictions or authorizations different from those described above. Security Interest in Receivables. Effective March 28, 2003, Texas Genco, LP, a subsidiary of Texas Genco, amended a Master Power Purchase and Sale Agreement with a subsidiary of Reliant Resources related to ERCOT power sales. Texas Genco, LP was granted a security interest in accounts receivable and/or securitization notes associated with the accounts receivable of certain subsidiaries of Reliant Resources to secure up to $250 million in purchase obligations. CRITICAL ACCOUNTING POLICIES A critical accounting policy is one that is both important to the presentation of our financial condition and results of operations and requires management to make difficult, subjective or complex accounting estimates. An accounting estimate is an approximation made by management of a financial statement element, item or account in the financial statements. Accounting estimates in our historical consolidated financial statements measure the effects of past business transactions or events, or the present status of an asset or liability. The accounting estimates 43

described below require us to make assumptions about matters that are highly uncertain at the time the estimate is made. Additionally, different estimates that we could have used or changes in an accounting estimate that are reasonably likely to occur could have a material impact on the presentation of our financial condition or results of operations. The circumstances that make these judgments difficult, subjective and/or complex have to do with the need to make estimates about the effect of matters that are inherently uncertain. Estimates and assumptions about future events and their effects cannot be predicted with certainty. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments. These estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as our operating environment changes. We believe the following critical accounting policies involve the application of accounting estimates for which a change in the estimate is inseparable from the effect of a change in accounting principle. Accordingly, these accounting policies have been reviewed and discussed with the audit committee of the board of directors. ACCOUNTING FOR RATE REGULATION SFAS No. 71, "Accounting for the Effects of Certain Types of Regulation" (SFAS No. 71), provides that rate-regulated entities account for and report assets and liabilities consistent with the recovery of those incurred costs in rates if the rates established are designed to recover the costs of providing the regulated service and if the competitive environment makes it probable that such rates can be charged and collected. Application of SFAS No. 71 to the electric generation portion of our business was discontinued as of June 30, 1999. Our Electric Transmission & Distribution business continues to apply SFAS No. 71 which results in our accounting for the regulatory effects of recovery of "stranded costs" and other "regulatory assets" resulting from the unbundling of the transmission and distribution business from our electric generation operations in our consolidated financial statements. Certain expenses and revenues subject to utility regulation or rate determination normally reflected in income are deferred on the balance sheet and are recognized in income as the related amounts are included in service rates and recovered from or refunded to customers. Regulatory assets reflected in our Consolidated Balance Sheets aggregated $4.0 billion and $4.6 billion as of December 31, 2002 and March 31, 2003, respectively. Additionally, regulatory liabilities reflected in our consolidated Balance Sheets aggregated $1.1 billion at both December 31, 2002 and March 31, 2003. Significant accounting estimates embedded within the application of SFAS No. 71 with respect to our Electric Transmission & Distribution business segment relate to $2.5 billion of recoverable electric generation plant mitigation assets (stranded costs) and $829 million of ECOM true-up as of March 31, 2003. The stranded costs are comprised of $1.1 billion of previously recorded accelerated depreciation and $841 million of previously redirected depreciation as well as $396 million related to the Texas Genco distribution. These stranded costs are recoverable under the provisions of the Texas electric restructuring law. The ultimate amount of stranded cost recovery is subject to a final determination which will occur in 2004 and is contingent upon the market value of Texas Genco. Any significant changes in our accounting estimate of stranded costs as a result of current market conditions or changes in the regulatory recovery mechanism currently in place could result in a material write-down of all or a portion of these regulatory assets. Regulatory assets related to ECOM true-up represent the regulatory assets associated with costs incurred as a result of mandated capacity auctions conducted beginning in 2002 by our Electric Generation business being consummated at market-based prices that have been substantially below the estimate of those prices made by the Texas Utility Commission in the spring of 2001. Any significant changes in our estimate of our regulatory asset associated with ECOM true-up could have a significant effect on our financial condition and results of operations. Additionally, any significant changes in our estimated stranded costs or ECOM true-up recovery could significantly affect our liquidity subsequent to the final true-up proceedings conducted by the Texas Utility Commission which are expected to conclude in late 2004. IMPAIRMENT OF LONG-LIVED ASSETS Long-lived assets recorded in our Consolidated Balance Sheets primarily consist of property, plant and equipment (PP&E). Net PP&E comprises $11.2 billion or 55% of our total assets as of March 31, 2003. We make judgments and estimates in conjunction with the carrying value of these assets, including amounts to be capitalized, depreciation and amortization methods and useful lives. We evaluate our PP&E for impairment whenever indicators of impairment exist. Accounting standards require that if the sum of the undiscounted expected future cash flows from a company's asset is less than the carrying value of the asset, an asset impairment must be recognized in the financial statements. The amount of impairment recognized is calculated by subtracting the fair value of the asset from the carrying value of the asset. 44

As a result of the distribution of approximately 19% of Texas Genco's common stock to our shareholders on January 6, 2003, we re-evaluated our electric generation assets for impairment as of December 31, 2002. This analysis required us to make long-term estimates of future cash receipts associated with the operation or sale of these electric generation assets and related cash outflows. These forecasts require assumptions about demand for electricity within the ERCOT market, future ERCOT market conditions, commodity prices and regulatory developments. As of December 31, 2002, no impairment had been indicated because the estimated cash flows associated with the operations of their assets exceeded their carrying value. However, the effects of competition within the ERCOT market, the results of our capacity auctions, and the timing and extent of changes in commodity prices, particularly natural gas prices, could have a significant effect on our future cash flows and, therefore, affect any future determination of asset impairment. IMPAIRMENT OF GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETS We evaluate our goodwill and other indefinite-lived intangible assets for impairment at least annually and more frequently when indicators of impairment exist. Accounting standards require that if the fair value of a reporting unit is less than its carrying value, including goodwill, a charge for impairment of goodwill must be recognized. To measure the amount of the impairment loss, we would compare the implied fair value of the reporting unit's goodwill with its carrying value. We recorded goodwill associated with the acquisition of our Natural Gas Distribution and Pipelines and Gathering operations in 1997. We reviewed our goodwill for impairment as of January 1, 2003. We computed the fair value of the Natural Gas Distribution and the Pipelines and Gathering operations as the sum of the discounted estimated net future cash flows applicable to each of these operations. We determined that the fair value for each of the Natural Gas Distribution operations and the Pipelines and Gathering operations exceeded their corresponding carrying value, including unallocated goodwill. We also concluded that no interim impairment indicators existed subsequent to this initial evaluation. As of March 31, 2003 we had recorded $1.7 billion of goodwill. Future evaluations of the carrying value of goodwill could be significantly impacted by our estimates of cash flows associated with our Natural Gas Distribution and Pipelines and Gathering operations, regulatory matters, and estimated operating costs. UNBILLED ENERGY REVENUES Revenues related to the sale and/or delivery of electricity or natural gas (energy) are generally recorded when energy is delivered to customers. However, the determination of energy sales to individual customers is based on the reading of their meters, which is performed on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is estimated. Unbilled electric delivery revenue is estimated each month based on daily supply volumes, applicable rates and analyses reflecting significant historical trends and experience. Unbilled natural gas sales are estimated based on estimated purchased gas volumes, estimated lost and unaccounted for gas and tariffed rates in effect. Accrued unbilled revenues recorded in the Consolidated Balance Sheets as of December 31, 2002 were $70 million related to our Electric Transmission & Distribution business segment and $284 million related to our Natural Gas Distribution business segment. Accrued unbilled revenues recorded in the Consolidated Balance Sheets as of March 31, 2003 were $61 million related to our Electric Transmission & Distribution business segment and $277 million related to our Natural Gas Distribution business segment. NEW ACCOUNTING PRONOUNCEMENTS Effective January 1, 2003, we adopted SFAS No. 143. SFAS No. 143 requires the fair value of an asset retirement obligation to be recognized as a liability is incurred and capitalized as part of the cost of the related tangible long-lived assets. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Retirement obligations associated with long-lived assets included within the scope of SFAS No. 143 are those for which a legal obligation exists under enacted laws, statutes and written or oral contracts, including obligations arising under the doctrine of promissory estoppel. We have identified retirement obligations for nuclear decommissioning at the South Texas Project and for lignite mine operations at the Jewett mine supplying the Limestone 45

electric generation facility. Prior to adoption of SFAS No. 143, we had recorded liabilities for nuclear decommissioning and the reclamation of the lignite mine. Liabilities were recorded for estimated decommissioning obligations of $139.7 million and $39.7 million for reclamation of the lignite at December 31, 2002. Upon adoption of SFAS No. 143 on January 1, 2003, we reversed the $139.7 million previously accrued for the nuclear decommissioning of the South Texas Project and recorded a plant asset of $99.1 million offset by accumulated depreciation of $35.8 million as well as a retirement obligation of $186.7 million. The $16.3 million difference between amounts previously recorded and the amounts recorded upon adoption of SFAS No. 143 is being deferred as a liability due to regulatory requirements. We also reversed the $39.7 million we had previously recorded for the Jewett mine reclamation and recorded a plant asset of $1.9 million offset by accumulated depreciation of $0.4 million as well as a retirement obligation of $3.8 million. The $37.4 million difference between amounts previously recorded and the amounts recorded upon adoption of SFAS No. 143 was recorded as a cumulative effect of accounting change. We have also identified other asset retirement obligations that cannot be calculated because the assets associated with the retirement obligations have an indeterminate life. The following represents the balances of the asset retirement obligation as of January 1, 2003 and the additions and accretion of the asset retirement obligation for the three months ended March 31, 2003:

Our rate-regulated businesses have previously recognized removal costs as a component of depreciation expense in accordance with regulatory treatment. As of March 31, 2003, these previously recognized removal costs of $639 46

million do not represent SFAS No. 143 asset retirement obligations, but rather embedded regulatory liabilities. Our non-rate regulated businesses have also previously recognized removal costs as component of depreciation expense. We reversed $115 million in the three months ended March 31, 2003 of previously recognized removal costs with respect to these non-rate-regulated businesses as a cumulative effect of accounting change. The total cumulative effect of accounting change from adoption of SFAS No. 143 was $152 million. Excluded from the $80 million after-tax cumulative effect of accounting change recorded for the three months ended March 31, 2003, is minority interest of $19 million related to the Texas Genco stock not owned by us. In April 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections" (SFAS No. 145). SFAS No. 145 eliminates the current requirement that gains and losses on debt extinguishment must be classified as extraordinary items in the income statement. Instead, such gains and losses will be classified as extraordinary items only if they are deemed to be unusual and infrequent. SFAS No. 145 also requires that capital leases that are modified so that the resulting lease agreement is classified as an operating lease be accounted for as a sale-leaseback transaction. The changes related to debt extinguishment are effective for fiscal years beginning after May 15, 2002, and the changes related to lease accounting are effective for transactions occurring after May 15, 2002. We have applied this guidance prospectively as it relates to lease accounting and will apply the accounting provisions related to debt extinguishment in 2003. Upon adoption of SFAS No. 145, any gain or loss on extinguishment of debt that was classified as an extraordinary item in prior periods will be reclassified. No such reclassification was required in the three month period ended March 31, 2002. We have reclassified the $26 million loss on debt extinguishment related to the fourth quarter of 2002 from extraordinary item to interest expense. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities" (SFAS No. 146). SFAS No. 146 nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)" (EITF No. 94-3). The principal difference between SFAS No. 146 and EITF No. 94-3 relates to the requirements for recognition of a liability for costs associated with an exit or disposal activity. SFAS No. 146 requires that a liability be recognized for a cost associated with an exit or disposal activity when it is incurred. A liability is incurred when a transaction or event occurs that leaves an entity little or no discretion to avoid the future transfer or use of assets to settle the liability. Under EITF No. 94-3, a liability for an exit cost was recognized at the date of an entity's commitment to an exit plan. In addition, SFAS No. 146 also requires that a liability for a cost associated with an exit or disposal activity be recognized at its fair value when it is incurred. SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. We will apply the provisions of SFAS No. 146 to all exit or disposal activities initiated after December 31, 2002. In November 2002, the FASB issued FASB Interpretation No. (FIN) 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others" (FIN 45). FIN 45 requires that a liability be recorded in the guarantor's balance sheet upon issuance of certain guarantees. In addition, FIN 45 requires disclosures about the guarantees that an entity has issued. The provision for initial recognition and measurement of the liability will be applied on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure provisions of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. The adoption of FIN 45 did not materially affect our consolidated financial statements. In January 2003, the FASB issued FIN 46, "Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51" (FIN 46). FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. We do not expect the adoption of FIN 46 to have a material impact on our results of operations or financial condition. 47

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK COMMODITY PRICE RISK We assess the risk of our non-trading derivatives (Energy Derivatives) using a sensitivity analysis method. The sensitivity analysis performed on our Energy Derivatives measures the potential loss based on a hypothetical 10% movement in energy prices. A decrease of 10% in the market prices of energy commodities from their March 31, 2003 levels would have decreased the fair value of our Energy Derivatives from their levels on that date by $28 million. The above analysis of the Energy Derivatives utilized for hedging purposes does not include the favorable impact that the same hypothetical price movement would have on our physical purchases and sales of natural gas to which the hedges relate. Furthermore, the Energy Derivative portfolio is managed to complement the physical transaction portfolio, reducing overall risks within limits. Therefore, the adverse impact to the fair value of the portfolio of Energy Derivatives held for hedging purposes associated with the hypothetical changes in commodity prices referenced above would be offset by a favorable impact on the underlying hedged physical transactions. INTEREST RATE RISK We have outstanding long-term debt, bank loans, mandatory redeemable preferred securities of subsidiary trusts holding solely our junior subordinated debentures (Trust Preferred Securities), securities held in our nuclear decommissioning trusts, some lease obligations and our obligations under the ZENS that subject us to the risk of loss associated with movements in market interest rates. We utilize interest-rate swaps in order to hedge a portion of our floating-rate debt. Our floating-rate obligations to third parties aggregated $5.1 billion at March 31, 2003. If the floating rates were to increase by 10% from March 31, 2003 rates, our combined interest expense to third parties would increase by a total of $3.2 million each month in which such increase continued. At March 31, 2003, we had outstanding fixed-rate debt (excluding indexed debt securities) and Trust Preferred Securities aggregating $6.1 billion in principal amount and having a fair value of $6.3 billion. These instruments are fixed-rate and, therefore, do not expose us to the risk of loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by approximately $332 million if interest rates were to decline by 10% from their levels at March 31, 2003. In general, such an increase in fair value would impact earnings and cash flows only if we were to reacquire all or a portion of these instruments in the open market prior to their maturity. As discussed in Note 13(f) to the CenterPoint Energy Notes, which note is incorporated herein by reference, we contribute $2.9 million per year to trusts established to fund our share of the decommissioning costs for the South Texas Project. The securities held by the trusts for decommissioning costs had an estimated fair value of $158 million as of March 31, 2003, of which approximately 48% were debt securities that subject us to risk of loss of fair value with movements in market interest rates. If interest rates were to increase by 10% from their levels at March 31, 2003, the fair value of the fixed-rate debt securities would decrease by approximately $1 million. Any unrealized gains or losses are accounted for as a long-term asset/liability as we will not benefit from any gains, and losses will be recovered through the rate making process. For further discussion regarding the recovery of decommissioning costs pursuant to the Texas electric restructuring law, please read Note 4(a) to the CenterPoint Energy Notes. As discussed in Note 9(b) to the CenterPoint Energy Notes, which note is incorporated herein by reference, CERC Corp.'s $240 million aggregate principal amount of TERM Notes outstanding at March 31, 2003, include an embedded option to remarket the securities. The option is expected to be exercised in the event that the ten-year Treasury rate is below 5.66%. At March 31, 2003, we could terminate the option at a cost of $31 million. A decrease of 10% in the March 31, 2003 level of interest rates would increase the cost of termination of the option by approximately $12 million. On April 14, 2003, CERC Corp. retired an additional $100 million principal amount of its TERM Notes obligations, leaving a remaining balance of $140 million of TERM Notes due November 1, 2003. As discussed in Note 7 to the CenterPoint Energy Notes, which note is incorporated herein by reference, upon adoption of SFAS No. 133 effective January 1, 2001, the ZENS obligation was bifurcated into a debt component and a derivative component. The debt component of $104 million at March 31, 2003 is a fixed-rate 48

obligation and, therefore, does not expose us to the risk of loss in earnings due to changes in market interest rates. However, the fair value of the debt component would increase by approximately $16 million if interest rates were to decline by 10% from levels at March 31, 2003. Changes in the fair value of the derivative component will be recorded in our Statements of Consolidated Income and, therefore, we are exposed to changes in the fair value of the derivative component as a result of changes in the underlying risk-free interest rate. If the risk-free interest rate were to increase by 10% from March 31, 2003 levels, the fair value of the derivative component would increase by approximately $4 million, which would be recorded as a loss in our Statements of Consolidated Income. As of March 31, 2003, we have interest rate swaps with an aggregate notional amount of $750 million that fix the interest rate applicable to floating rate short-term debt. At March 31, 2003, the swaps relating to short-term debt could be terminated at a cost of $14 million. These swaps do not qualify as cash flow hedges under SFAS No. 133, and are marked to market in the Company's Consolidated Balance Sheets with changes reflected in interest expense in the Statements of Consolidated Income. A decrease of 10% in the March 31, 2003 level of interest rates would increase the cost of terminating the swaps at March 31, 2003 by $1 million. EQUITY MARKET VALUE RISK We are exposed to equity market value risk through our ownership of approximately 22 million shares of AOL TW common stock, which we hold to facilitate our ability to meet our obligations under the ZENS. Please read Note 7 to the CenterPoint Energy Notes for a discussion of the effect of adoption of SFAS No. 133 on our ZENS obligation and our historical accounting treatment of our ZENS obligation. Subsequent to adoption of SFAS No. 133, a decrease of 10% from the March 31, 2003 market value of AOL Time Warner common stock would result in a net loss of approximately $3 million, which would be recorded as a loss in our Statements of Consolidated Income. As discussed above under "-- Interest Rate Risk," we contribute to trusts established to fund our share of the decommissioning costs for the South Texas Project, which held debt and equity securities as of March 31, 2003. The equity securities expose us to losses in fair value. If the market prices of the individual equity securities were to decrease by 10% from their levels at March 31, 2003, the resulting loss in fair value of these securities would be approximately $8 million. Currently, the risk of an economic loss is mitigated as discussed above under "-- Interest Rate Risk." ITEM 4. CONTROLS AND PROCEDURES Within the 90 days prior to the date of this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-14 of the Securities Exchange Act of 1934. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures are effective in timely alerting them to material information relating to us (including our consolidated subsidiaries) required to be included in our periodic SEC filings. Subsequent to the date of their evaluation, there were no significant changes in our internal controls or in other factors that could significantly affect the internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses. 49

If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Revolving Advances comprising such Revolving Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender's Revolving Advance as part of such Revolving Borrowing for purposes of this Agreement. (e) The failure of any Lender to make the Revolving Advance to be made by it as part of any Revolving Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Revolving Advance on the date of such Revolving Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Revolving Advance to be made by such other Lender on the date of any Revolving Borrowing. SECTION 2.03. The CAF Advances. (a) From time to time on any Business Day during the period from the Effective Date until the Termination Date, the Borrower may request CAF Advances from the Lenders in amounts such that the Total Aggregate Outstanding Extensions of Credit at any time shall not exceed the Total Commitments at such time (the "CAF Facility"). (b) Under the terms and conditions set forth below, the Borrower may borrow, repay pursuant to Section 2.07 and reborrow under this Section 2.03. SECTION 2.04. Competitive Bid Procedure. (a) In order to request a CAF Advance, the Borrower shall deliver to the Administrative Agent a written notice in the form of Exhibit E, attached hereto (a "Competitive Bid Request"), to be received by the Administrative Agent (i) in the case of each CAF Eurodollar Rate Advance, not later than 3:00 P.M. (New York City time), four (4) Business Days before the Borrowing Date specified for such CAF Eurodollar Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than 11:00 A.M. (New York City time), one (1) Business Day before the Borrowing Date specified for such Fixed Rate Advance. Each Competitive Bid Request shall in each case refer to this Agreement and specify (i) the date of Borrowing of such CAF Advances (which shall be a Business Day), (ii) the aggregate principal amount thereof, (iii) whether the CAF Advances then being requested are to be CAF Eurodollar Rate Advances or Fixed Rate Advances, (iv) the maturity date for each CAF Advance requested to be made and (v) the interest payment dates for each CAF Advance requested to be made. The Administrative Agent shall promptly notify each Lender by telex or facsimile transmission of the contents of each Competitive Bid Request received by it. Each Competitive Bid Request may solicit bids for CAF Advances in an aggregate principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and for not more than three alternative maturity dates for such CAF Advances. The maturity date for each CAF Advance shall be not less than 15 days nor more than 180 days after the applicable date of CAF Borrowing (and in any event shall not extend beyond the Termination Date). (b) Each Lender may, in its sole discretion, irrevocably offer to make one or more CAF Advances to the Borrower responsive to each Competitive Bid Request from the Borrower. Any such irrevocable offer by a Lender must be received by the Administrative Agent, in the form of Exhibit F hereto (a "Competitive Bid"), (i) in the case of each CAF Eurodollar Rate Advance, not later than 10:30 A.M. (New York City time), three (3) Business Days before the Borrowing Date specified for such CAF Eurodollar Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than 9:30 A.M. (New York City time) on the Borrowing Date specified for such Fixed Rate Advance. Competitive Bids that do not conform substantially to the format of Exhibit F may be rejected by the Administrative Agent after conferring with, and upon the instruction of, the Borrower, and the Administrative Agent shall notify the Lender of such rejection as soon as practicable. Each Competitive Bid shall refer to this Agreement and (i) specify the maximum principal amount of CAF Advances for each maturity date (which shall be in an aggregate principal amount not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof and which may equal, but not exceed, the principal amount requested for such maturity date by the Borrower) and the CERC 364-Day Revolving Credit Agreement

19 aggregate maximum principal amount of CAF Advances for all maturity dates (which amount, with respect to any Lender, may exceed such Lender's Commitment) that the Lender is willing to make to the Borrower, and (ii) specify the CAF Rate at which the Lender is prepared to make each such CAF Advance. A Competitive Bid submitted by a Lender pursuant to this Section 2.04(b) shall be irrevocable absent manifest error. (c) The Administrative Agent shall (i) in the case of each CAF Eurodollar Rate Advance, not later than 11:00 A.M. (New York City time) three (3) Business Days before the Borrowing Date specified for such CAF Eurodollar Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than 10:00 A.M. (New York City time) on the Borrowing Date specified for such Fixed Rate Advance, notify the Borrower in writing of all the Competitive Bids made (arranging each such bid in ascending interest rate order), and the CAF Rate or Rates and the maximum principal amount of each CAF Advance in respect of which a Competitive Bid was made, and the identity of the Lender that made each bid. The Administrative Agent shall send a copy of all Competitive Bids to the Borrower for its records as soon as practicable after completion of the bidding process set forth in this Section 2.04. (d) The Borrower may in its sole and absolute discretion, subject only to the provisions of this Section 2.04(d), accept or reject any Competitive Bid referred to in Section 2.04(c); provided, however, that the aggregate amount of the Competitive Bids for CAF Advances so accepted by the Borrower may not exceed the lesser of (i) the principal amount of the applicable CAF Borrowing requested by the Borrower in respect thereof and (ii) the amount of the Commitments less the Total Aggregate Outstanding Extensions of Credit then outstanding, after giving effect to the application of the proceeds of such respective CAF Borrowing on the Borrowing Date therefor. The Borrower shall notify the Administrative Agent in writing whether and to what extent it has decided to accept or reject any or all of the bids referred to in Section 2.04(c) by delivering to the Administrative Agent a written notice in the form of Exhibit G hereto (a "Competitive Bid Confirmation"), (i) in the case of each CAF Eurodollar Rate Advance, not later than 1:00 P.M. (New York City time), three (3) Business Days before the Borrowing Date specified for such CAF Eurodollar Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than 11:00 A.M. (New York City time) on the Borrowing Date specified for such Fixed Rate Advance, which Competitive Bid Confirmation shall specify the principal amount of CAF Advances for each relevant maturity date to be made by each such bidding Lender (which amount for each such maturity date shall be equal to or less than the maximum amount for such maturity date specified in the Competitive Bid of such Lender, and for all maturity dates included in such Competitive Bid in respect thereof shall be equal to or less than the aggregate maximum amount specified in such Competitive Bid for all such maturity dates); provided, however, that (A) the failure by the Borrower to so deliver a Competitive Bid Confirmation by the specified time shall be deemed to be a rejection of all the bids referred to in Section 2.04(c) for the related Competitive Bid Request; (B) the Borrower shall not accept a bid made at a particular CAF Rate for a particular maturity if the Borrower has decided to reject a bid made at a lower CAF Rate for such maturity; (C) if the Borrower shall accept bids made at a particular CAF Rate for a particular maturity but shall be restricted by other conditions hereof from borrowing the maximum principal amount of CAF Advances in respect of which bids at such CAF Rate have been made, then the Borrower shall accept a pro rata portion of each bid made at such CAF Rate based as nearly as possible on the respective maximum principal amounts of CAF Advances offered to be made by the relevant Lenders pursuant to such bids; and (D) no bid shall be accepted for a CAF Advance by any Lender unless such CAF Advance is in an aggregate principal amount not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Notwithstanding the foregoing, if it is necessary for the Borrower to accept a pro rata allocation of the bids made in response to a Competitive Bid Request (whether pursuant to the events specified in clause (C) above or otherwise) and the available principal amount of CAF Advances to be allocated among the Lenders is not sufficient to enable CAF Advances to be allocated to each Lender in an aggregate principal amount not less than $5,000,000 or in integral multiples of $1,000,000 in excess thereof, then the Borrower shall, subject to clause (D) above, select the Lenders to be allocated such CAF Advances and shall round allocations up or down to the next higher or lower multiple of $1,000,000 as it shall deem appropriate; provided that the allocations among the Lenders to be allocated such CAF Advances shall be made pro rata based as nearly as possible on the respective maximum principal amounts of CAF Advances offered to be made by such Lenders. The Competitive Bid Confirmation given by the Borrower pursuant to this Section 2.04(d) shall be irrevocable. (e) Upon receipt from the Administrative Agent of the Eurodollar Rate applicable to any CAF Eurodollar Rate Advance to be made by any Lender pursuant to a Competitive Bid that has been accepted by the Borrower pursuant to this Section 2.04, the Administrative Agent shall notify such Lender of the applicable Eurodollar Rate. CERC 364-Day Revolving Credit Agreement

20 (f) If the Administrative Agent shall at any time elect to submit a Competitive Bid in its capacity as a Lender, it shall submit such bid directly to the Borrower by (i) in the case of a CAF Eurodollar Rate Advance, not later than 10:15 A.M. (New York City time), and (ii) in the case of a Fixed Rate Advance, not later than 9:15 A.M. (New York City time), in each case, on the Business Day on which the other Lenders are required to submit their bids to the Administrative Agent pursuant to Section 2.04(b) above. (g) If the Borrower accepts pursuant to Section 2.04(d) one or more of the offers made by any Lender or Lenders, the Administrative Agent shall promptly notify each Lender that has made such an offer of the aggregate amount of such CAF Advances to be made on the Borrowing Date for each maturity date and of the acceptance or rejection of any offers to make such CAF Advances made by such Lender. Each Lender that is to make a CAF Advance shall, before 12:00 Noon (New York City time) on the Borrowing Date specified in the Competitive Bid Request applicable thereto, make available to the Administrative Agent at its office set forth in Section 8.02 the amount of CAF Advances to be made by such Lender, in immediately available funds. The Administrative Agent shall, no later than 1:00 P.M. (New York City time) on such Borrowing Date, make such funds available to the Borrower at the Borrower's account as shall be designated by it to the Administrative Agent from time to time. As soon as practicable after each Borrowing Date, the Administrative Agent shall notify each Lender of the aggregate amount of CAF Advances advanced on such Borrowing Date and the respective maturity dates thereof. (h) The Borrower shall repay to the Administrative Agent for the account of each Lender that has made a CAF Advance (or the Eligible Assignee in respect thereof, as the case may be) on the maturity date of each CAF Advance (such maturity date being that specified by the Borrower for repayment of such CAF Advance in the related Competitive Bid Request) the then unpaid principal amount of such CAF Advance. The Borrower shall not, without the consent of the relevant Lender, have the right to prepay, at its option, any principal amount of any CAF Advance. All notices required by this Section 2.04 shall be made in accordance with Section 8.02 hereof; provided, however, that each request or notice required to be made under Section 2.04(a) or 2.04(d) by the Borrower may be made by the giving of telephone notice to the Administrative Agent that is promptly confirmed by delivery of a notice in writing (in substantially the form of Exhibit B or Exhibit E, as the case may be) to the Administrative Agent. SECTION 2.05. Fees. (a) Facility Fee. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee on the aggregate amount of such Lender's Commitment, irrespective of usage, from the Effective Date in the case of each Initial Lender and from the effective date specified in the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender until the Termination Date at a rate per annum equal to the Applicable Percentage in effect from time to time, payable in arrears quarterly on the last day of each March, June, September and December, commencing June 30, 2003, and on the Termination Date. (b) Agents' Fees. The Borrower shall pay to each Agent for its own account such fees as may from time to time be agreed between the Borrower and such Agent. SECTION 2.06. Termination or Reduction of the Commitments. The Borrower shall have the right, upon at least three Business Days' notice to the Administrative Agent, to terminate in whole or permanently reduce ratably in part the unused portions of the respective Commitments of the Lenders, provided that (i) each partial reduction shall be in a minimum aggregate amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) no such termination or reduction shall be permitted if, after giving effect thereto and to any prepayments made under Section 2.11 by the Borrower on the effective date thereof, the Total Aggregate Outstanding Extensions of Credit then outstanding would exceed the Total Commitments then in effect. Any terminated or permanently reduced portion of the respective Commitments of the Lenders may not be reinstated. Each reduction of Commitments pursuant to this Section 2.06 shall be applied pro rata to the Commitments of each Lender. If at any time, including after giving effect to any reduction of Commitments pursuant to this Section 2.06, the Total Aggregate Outstanding Extensions of Credit exceed the Total Commitments, the Borrower shall be obligated, first, to prepay the Revolving Advances in the amount of such excess and second, to prepay the CAF Advances (whether or not consented to by the relevant Lender) to the extent that the aggregate amount of CAF Advances exceeds such Total Commitments after prepayment of all Revolving Advances. CERC 364-Day Revolving Credit Agreement

21 SECTION 2.07. Repayment. The Borrower shall repay to the Administrative Agent for the ratable account of the Lenders on the Termination Date the aggregate principal amount of the Revolving Advances then outstanding. SECTION 2.08. Interest. (a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal amount of each Revolving Advance owing to each Lender from the date of such Revolving Advance to but excluding the date such principal amount shall be paid in full, at the following rates per annum: (i) Base Rate Advances. During such periods as such Revolving Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time, payable in arrears quarterly on the last day of each March, June, September and December, during such periods and on the date such Base Rate Advance shall be Converted or paid in full. (ii) Eurodollar Rate Advances. During such periods as such Advance is a Revolving Advance bearing interest at the Eurodollar Rate, a rate per annum equal at all times during each Interest Period for such Revolving Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Revolving Advance plus (y) the Applicable Margin in effect from time to time, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full. (iii) CAF Eurodollar Rate Advances. In the case of each CAF Eurodollar Rate Advance, a rate per annum equal at all times to the sum of the Eurodollar Rate applicable to such CAF Advance plus or minus, as the case may be, the CAF Margin specified by a Lender with respect to such CAF Advance in its Competitive Bid submitted pursuant to Section 2.04(b), payable on the date or dates specified in the relevant Competitive Bid Request. (b) Default Interest. Upon the occurrence and during the continuance of any default in the payment of any amount owed hereunder, the Administrative Agent may, and upon the request of the Required Lenders shall, require the Borrower to pay interest ("Default Interest") on (i) the unpaid principal amount of each Revolving Advance past due and owing to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all times to 2.00% per annum above the rate per annum required to be paid on such Revolving Advance pursuant to clause (a)(i), (a)(ii) or (a)(iii) above and (ii) to the fullest extent permitted by law, the amount of any interest, fee or other amount payable hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2.00% per annum above the rate per annum required to be paid on Base Rate Advances pursuant to clause (a)(i) above; provided, however, that following acceleration of the Advances pursuant to Section 6.01, Default Interest shall accrue and be payable hereunder whether or not previously required by the Administrative Agent. SECTION 2.09. Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.08(a)(i), (ii) or (iii). (b) If, with respect to any Eurodollar Rate Advances, the Required Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Revolving Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to Convert Revolving Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. (c) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.01, the Administrative CERC 364-Day Revolving Credit Agreement

22 Agent will forthwith so notify the Borrower and the Lenders and such Revolving Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances. If no Advances are outstanding at the time of delivery of a Notice of Borrowing with respect to Eurodollar Rate Advances and the Borrower shall fail to select an Interest Period for such Advances, such Advances shall be made as Base Rate Advances. (d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Revolving Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Revolving Advances shall automatically Convert into Base Rate Advances. (e) Upon the occurrence and during the continuance of any Event of Default under Section 6.01(a), (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Revolving Advances into, Eurodollar Rate Advances shall be suspended. SECTION 2.10. Optional Conversion of Revolving Advances. The Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.09 and 2.13, Convert all Revolving Advances of one Type comprising the same Borrowing into Revolving Advances of the other Type; provided, however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not less than the minimum amount specified in Section 2.02(b) and no Conversion of any Revolving Advances shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Revolving Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower. SECTION 2.11. Prepayments of Revolving Advances. (a) Optional Prepayments. The Borrower may, upon at least two Business Days' notice to the Administrative Agent, in the case of a Revolving Borrowing consisting of Eurodollar Rate Advances, or upon same day notice to the Administrative Agent, in the case of a Revolving Borrowing consisting of Base Rate Advances, stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Revolving Advances comprising part of the same Revolving Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in a minimum aggregate principal amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c). (b) Mandatory Prepayments from Excess Cash Flow. The Borrower shall, on the day the Borrower files its Form 10-Q or Form 10-K, but not later than 45 days following the end of each calendar quarter (the "Prepayment Date" and the "Reference Quarter", respectively), prepay an aggregate principal amount of the Revolving Advances comprising part of the same Revolving Borrowings in an amount sufficient to cause the aggregate principal amount of all Advances outstanding as of the Prepayment Date to equal the aggregate principal amount of all Advances outstanding as of the first day of the Reference Quarter, less the amount of Excess Cash Flow for the Reference Quarter. Amounts prepaid under this Section 2.11(b) shall be available to be reborrowed on the following Business Day, provided that all other conditions to such Borrowing under this Agreement are met. SECTION 2.12. Increased Costs. (a) If, after the date hereof, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances or CAF Eurodollar Rate Advances (excluding for purposes of this Section 2.12 any such increased costs resulting from (A) Taxes or Other Taxes (as to which Section 2.15 shall govern), (B) net income taxes and franchise taxes imposed on such Lender as a result of a present or former connection between the jurisdiction of the government or taxing authority imposing such tax and such Lender other than a connection arising solely from such Lender having CERC 364-Day Revolving Credit Agreement

23 executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or the Advances and (C) changes in the rate of tax on the overall net income of such Lender), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such actual increased cost; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate as to the amount of such increased cost, submitted to the Borrower and the Administrative Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error. (b) If any Lender determines in good faith that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend hereunder. A certificate as to such amounts submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error. (c) The agreements contained in this Section 2.12 shall survive the termination of this Agreement and the payment of all amounts payable hereunder; provided, however, that in no event shall the Borrower be obligated to reimburse or compensate any Lender for amounts contemplated by this Section 2.12 for any period prior to the date that is 90 days prior to the date upon which such Lender requests in writing such reimbursement or compensation from the Borrower. SECTION 2.13. Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that it has determined in good faith that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or CAF Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances or CAF Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance or CAF Eurodollar Rate Advance, as the case may be, will automatically, upon such demand, Convert into a Base Rate Advance or an Advance that bears interest at the rate set forth in Section 2.08(a)(i), as the case may be, and (b) the obligation of the Lenders to make Eurodollar Rate Advances or CAF Eurodollar Rate Advances or to Convert Revolving Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or CAF Eurodollar Rate Advances, as the case may be, or to continue to fund or maintain Eurodollar Rate Advances or CAF Eurodollar Rate Advances, as the case may be, and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. SECTION 2.14. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the Notes (if any), irrespective of any right of counterclaim or set-off, not later than 12:00 Noon (New York City time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent's Account in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or facility fees ratably (other than amounts payable pursuant to Sections 2.04, 2.12, 2.15 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information CERC 364-Day Revolving Credit Agreement

24 contained therein in the Register pursuant to Section 8.07(c), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the Notes or CAF Notes (if any) in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. (b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder or under the Note or CAF Note, as the case may be, held by such Lender (if any), to charge from time to time against any or all of the Borrower's accounts with such Lender any amount so due. (c) All computations of interest based on the Base Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate, the CAF Rate or the Federal Funds Rate or in respect of Fixed Rate Advances and of facility fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or facility fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be prima facie evidence of the correctness thereof. (d) Whenever any payment hereunder or under the Notes or CAF Notes (if any) shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances or CAF Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate. SECTION 2.15. Taxes. (a) Any and all payments by the Borrower to or for the account of any Lender or the Administrative Agent hereunder or under the Notes or CAF Notes (if any) or any other documents to be delivered hereunder shall be made, in accordance with Section 2.14 or the applicable provisions of such other documents, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Administrative Agent, net income taxes and franchise taxes imposed on it as a result of a present or former connection between the jurisdiction of the government or taxing authority imposing such tax and the Administrative Agent or such Lender other than a connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any Note or CAF Note, if any (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes or CAF Notes (if any) being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note or CAF Note or any other documents to be delivered hereunder to any Lender or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.15) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law; provided, however, that the Borrower shall not be required to increase any such sums payable to any Lender with respect to any Taxes (i) that are attributable to such Lender's failure to comply with the requirements of Section 2.15(e) or (ii) that are United States withholding taxes imposed on sums payable to such Lender at the time such Lender becomes a party CERC 364-Day Revolving Credit Agreement

25 to this Agreement, except to the extent that any such Lender's assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Taxes pursuant to this Section 2.15. Whenever any Taxes or Other Taxes (as defined in Section 2.15(b)) are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for the account of the relevant Lender or Administrative Agent, as the case may be, either (A) official tax receipts or notarized copies of such receipts to such Lender within thirty (30) days after payment of any applicable tax or (B) a certificate executed by a Responsible Officer of the Borrower confirming that such Taxes or Other Taxes have been paid, together with evidence of such payment. (b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or CAF Notes (if any) or any other documents to be delivered hereunder or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes or CAF Notes (if any) or any other documents to be delivered hereunder (hereinafter referred to as "Other Taxes"). (c) The Borrower shall indemnify each Lender and the Administrative Agent for and hold it harmless against the full amount of Taxes or Other Taxes (including, without limitation, taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.15) imposed on or paid by such Lender or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. (d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. In the case of any payment hereunder or under the Notes or CAF Notes (if any) or any other documents to be delivered hereunder by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of this subsection (d) and subsection (e), the terms "United States" and "United States person" shall have the meanings specified in Section 7701 of the Internal Revenue Code. (e) Each Lender registered in the Register that is not a United States person as defined in Section 7701(a)(30) of the Internal Revenue Code agrees that it will deliver to the Borrower and the Administrative Agent on the Effective Date, or on the date which it becomes a party to this Agreement, two duly completed copies of United States Internal Revenue Service Form W-8BEN, W-8ECI, W-8EXP or W-8IMY (or other appropriate corresponding form) or any successor applicable form, as the case may be. Each such Lender also agrees to deliver to the Borrower and the Administrative Agent two further copies of the said Form W-8BEN, W-8ECI, W-8EXP or W-8IMY or successor applicable forms or other manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower, and such extensions or renewals thereof as may reasonably be requested by the Borrower or the Administrative Agent, unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required that renders all such forms inapplicable or that would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Administrative Agent. Each such Lender shall certify in the case of a Form W-8BEN, W-8ECI, W-8EXP or W-8IMY that is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. In the event that any such Lender fails to deliver any forms required under this Section 2.15(e), the Borrower's obligation to pay additional amounts shall be reduced to the amount that it would have been obligated to pay had such forms been provided. (f) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form, certificate or other document described in Section 2.15(e) (other than if such failure is due to a change in law, or in the interpretation or application thereof, occurring subsequent to the date on which a form, certificate or other document originally was required to be provided, or if such form, certificate or other document otherwise is not CERC 364-Day Revolving Credit Agreement

26 required under subsection (e) above), such Lender shall not be entitled to indemnification under Section 2.15(a) or (c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes. (g) Any Lender claiming any additional amounts payable pursuant to this Section 2.15 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. (h) If any Taxes or Other Taxes are not correctly or legally asserted and the Agent or any Lender determines, in its sole discretion, that it has received a refund of those Taxes or Other Taxes as to which it has been indemnified by the Borrower, the Administrative Agent or such Lender shall within 20 days after such refund pay to the Borrower the amount of such refund to the extent that the Borrower indemnified the Administrative Agent or such Lender for such Taxes or Other Taxes pursuant to this Section 2.15, net of any out-of-pocket costs of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person. SECTION 2.16. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Revolving Advances owing to it (other than pursuant to Sections 2.12, 2.15 or 8.04(c)) in excess of its ratable share of payments on account of the Revolving Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Revolving Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. SECTION 2.17. Use of Proceeds. The proceeds of the Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely for working capital, including capital expenditures, and to repay commercial paper. SECTION 2.18. Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Advance owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. The Borrower agrees that upon notice by any Lender to the Borrower (with a copy of such notice to the Administrative Agent) to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to be made by, such Lender, the Borrower shall promptly execute and deliver to such Lender, with a copy to the Administrative Agent, a Note or a CAF Note, as the case may be, in substantially the form of Exhibit A or Exhibit D hereto, respectively and as the case may be, payable to the order of such Lender in a principal amount equal to the amount of the Revolving Advance or the CAF Advance, as CERC 364-Day Revolving Credit Agreement

27 the case may be, of such Lender. All references to Notes or CAF Notes in the Loan Documents shall mean Notes or CAF Notes, respectively and if any, to the extent issued hereunder.

(c) Entries made in good faith by the Administrative Agent in the Register pursuant to subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement, absent manifest error; provided, however, that the failure of the Administrative Agent or such Lender Party to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement.

Grant of Security. The Grantor hereby grants to the Collateral Agent, for the ratable benefit of the Secured Parties, a security interest in, the Grantor's right, title and interest in and to the following, in each case, as to each type of property described below, whether now owned or hereafter acquired by the Grantor, wherever located, and whether now or hereafter existing or arising (collectively, the "COLLATERAL"): (a) the following (the "SECURITY COLLATERAL"): (i) the Initial Pledged Equity and the certificates, if any, representing the Initial Pledged Equity, and all dividends, distributions, return of capital, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the Initial Pledged Equity and all subscription warrants, rights or options issued thereon or with respect thereto; (ii) all additional shares of stock and other Equity Interests of or in any issuer of the Initial Pledged Equity or any successor entity from time to time acquired by the Grantor in any manner (such shares and other Equity Interests, together with the Initial Pledged Equity, being the "PLEDGED EQUITY"), and the certificates, if any, representing such additional shares or other Equity Interests, and all dividends, distributions, return of capital, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such shares or other Equity Interests and all subscription warrants, rights or options issued thereon or with respect thereto; (iii) the Initial Pledged Debt and the instruments, if any, evidencing the Initial Pledged Debt, and all interest, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the Initial Pledged Debt; and (b) all proceeds of, collateral for, income and other payments now or hereafter due and payable with respect to, and supporting obligations relating to, any and all of the CERC - Pledge Agreement

Section 3. Delivery and Control of Security Collateral. (a) All certificates or instruments representing or evidencing Security Collateral shall be delivered to and held by or on behalf of the Collateral Agent pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Collateral Agent. The Collateral Agent shall have the right, at any time after the occurrence and during the continuation of an Event of Default, in its reasonable discretion and without notice to the Grantor, to transfer to or to register in the name of the Collateral Agent or any of its nominees any or all of the Security Collateral, subject only to the revocable rights specified in Section 7(a). In addition, after the occurrence and during the continuation of an Event of Default, the Collateral Agent shall have the right to exchange certificates or instruments representing or evidencing Security Collateral for certificates or instruments of smaller or larger denominations. (b) With respect to any Security Collateral in which the Grantor has any right, title or interest and that constitutes an uncertificated security, the Grantor will cause the issuer thereof either (i) to register the Collateral Agent as the registered owner of such security or (ii) to agree in an authenticated record with the Grantor and the Collateral Agent that such issuer will comply with instructions with respect to such security originated by the Collateral Agent without further consent of the Grantor, such authenticated record to be in form and substance satisfactory to the Collateral Agent. With respect to any Security Collateral in which the Grantor has any right, title or interest and that is not an uncertificated security, upon the request of the Collateral Agent upon the occurrence and during the continuance of an Event of Default, the Grantor will notify each such issuer of Pledged Equity that such Pledged Equity is subject to the security interest granted hereunder.

(b) The Grantor is the legal and beneficial owner of the Collateral of the Grantor free and clear of any Lien, claim, option or right of others, except for the security interest created under this Agreement or as otherwise permitted under each Credit Agreement. No effective financing statement or other instrument similar in effect covering all or any part of such Collateral or listing the Grantor or any trade name of the Grantor as debtor is on file in any recording office, except such as may have been filed in favor of the Collateral Agent relating to the Loan Documents or as otherwise permitted under each Credit Agreement. (c) The Pledged Equity pledged by the Grantor hereunder has been duly authorized and validly issued and is fully paid and non-assessable. With respect to any Pledged Equity that is an uncertificated security, the Grantor has caused the issuer thereof either (i) to register the Collateral Agent as the registered owner of such security or (ii) to agree in an authenticated record with the Grantor and the Collateral Agent that such issuer will, upon the occurrence and during the continuation of an Event of Default, comply with instructions with respect to such security originated by the Collateral Agent without further consent of the Grantor. The Initial Pledged Debt pledged by such Grantor hereunder has been duly authorized, authenticated or issued and delivered, is the legal, valid and binding obligation of the issuers thereof, is evidenced by one or more promissory notes (which notes have been delivered to the Collateral Agent) and is not in default. (d) The Initial Pledged Equity pledged by the Grantor constitutes the percentage of the issued and outstanding Equity Interests of the issuers thereof indicated on Schedule II hereto. The Initial Pledged Debt constitutes all of the outstanding indebtedness owed to such Grantor by the issuer thereof and is outstanding in the principal amount indicated on Schedule II hereto. (e) All filings and other actions (including, without limitation, actions necessary to obtain control of Collateral as provided in Section 9-106 of the UCC) necessary to perfect the security interest in the Collateral of the Grantor created under this Agreement have been duly made or taken and are in full force and effect, and this Agreement creates in favor of the Collateral Agent for the benefit of the Secured Parties a valid and, together with such filings and other actions, perfected first priority security interest in the Collateral, securing the payment of the Secured Obligations. (f) No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for (i) the grant by the Grantor of the security interest granted hereunder or for the execution, delivery or performance of this Agreement by the Grantor, (ii) the perfection or maintenance of the security interest created hereunder (including the first priority CERC - Pledge Agreement

5 nature of such security interest), except for the filing of financing and continuation statements under the UCC, which financing statements have been duly filed and are in full force and effect, and the actions described in Section 3 with respect to Security Collateral, which actions have been taken and are in full force and effect, or (iii) the exercise by the Collateral Agent of its voting or other rights provided for in this Agreement or the remedies in respect of the Collateral pursuant to this Agreement, except as may be required in connection with the disposition of any portion of the Security Collateral by laws affecting the offering and sale of securities generally. Section 5. Further Assurances. (a) The Grantor agrees that from time to time, at the expense of the Grantor, the Grantor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that may be necessary or desirable, or that the Collateral Agent may reasonably request, in order to perfect and protect any pledge or security interest granted or purported to be granted by the Grantor hereunder or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral of the Grantor. Without limiting the generality of the foregoing, the Grantor will promptly with respect to Collateral of the Grantor: (i) if any such Collateral shall be evidenced by a promissory note or other instrument, deliver and pledge to the Collateral Agent hereunder such note or instrument duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance satisfactory to the Collateral Agent; (ii) execute or authenticate and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Collateral Agent may request, in order to perfect and preserve the security interest granted or purported to be granted by the Grantor hereunder; (iii) deliver and pledge to the Collateral Agent for benefit of the Secured Parties certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; (iv) take all action necessary to ensure that the Collateral Agent has control of Collateral consisting of investment property as provided in Section 9-106 of the UCC; and (v) deliver to the Collateral Agent evidence that all other action that the Collateral Agent may deem reasonably necessary or desirable in order to perfect and protect the security interest created by the Grantor under this Agreement has been taken. (b) The Grantor hereby authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, in each case without the signature of the Grantor, and regardless of whether any particular asset described in such financing statements falls within the scope of the UCC or the granting clause of this Agreement. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. The Grantor ratifies its authorization for the Collateral Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

The Grantor will not become bound by a security agreement authenticated by another Person (determined as provided in Section 9-203(d) of the UCC) without giving the Collateral Agent 10 Business Days' prior written notice thereof and taking all action required by the Collateral Agent to ensure that the perfection and first priority nature of the Collateral Agent's security interest in the Collateral will be maintained. (b) The Grantor will hold and preserve its records relating to the Collateral and will permit up to six representatives of the Bridge Secured Parties designated by the Required Lenders (as defined in the Bridge Credit Agreement) or representatives of the Collateral Agent, on not less than five (5) Business Days' notice, at any reasonable time during normal business hours, to inspect and make copies of abstracts from such records and other documents and to discuss general business affairs of the Grantor with its officers; subject, however, in all cases to the imposition of such conditions as the Grantor shall deem necessary based on reasonable considerations of safety and security; provided, however, that the Grantor shall not be required to disclose to the Collateral Agent or any Secured Party or representatives thereof any information which is the subject of attorney-client privilege or attorney work-product privilege properly asserted by the Grantor to prevent the loss of such privilege in connection with such information or which is prevented from disclosure pursuant to a confidentiality agreement with third parties. Notwithstanding the foregoing, none of the conditions as to the exercise of the right of access described in the preceding sentence that relate to notice requirements or limitations on the Persons permitted to exercise such right shall apply at any time when a Default or an Event of Default shall have occurred (as each such term is defined in either of the Credit Agreements). (c) If the Grantor does not have an organizational identification number and later obtains one, it will forthwith notify the Collateral Agent of such organizational identification number. Section 7. Voting Rights; Dividends; Etc. (a) So long as no Event of Default shall have occurred and be continuing: (i) The Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral or any part thereof for any purpose; provided however, that the Grantor will not exercise or refrain from exercising any such right if such action would have a material adverse effect on the value of the Security Collateral or any part thereof.

(iii) The Collateral Agent will execute and deliver (or cause to be executed and delivered) to the Grantor all such proxies and other instruments as the Grantor may reasonably request for the purpose of enabling the Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above. (b) Upon the occurrence and during the continuance of an Event of Default: (i) All rights of the Grantor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 7(a)(i) shall, upon notice to the Grantor by the Collateral Agent, cease and (y) to receive the dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 7(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions.

8 or suffer to exist any Lien upon or with respect to any of the Collateral of the Grantor except for the pledge, assignment and security interest created under this Agreement and Permitted Liens. (b) The Grantor agrees that it will (i) cause each issuer of the Pledged Equity pledged by the Grantor not to issue any Equity Interests or other securities in addition to or in substitution for the Pledged Equity issued by such issuer, except to the Grantor, and (ii) pledge hereunder, immediately upon its acquisition (directly or indirectly) thereof, any and all additional Equity Interests or other securities of each issuer of the Pledged Equity. Section 9. Collateral Agent Appointed Attorney-in-Fact. The Grantor hereby irrevocably appoints the Collateral Agent the Grantor's attorney-in-fact, with full authority in the place and stead of the Grantor and in the name of the Grantor or otherwise, from time to time, upon the occurrence and during the continuance of an Event of Default, in the Collateral Agent's reasonable discretion, to take any action and to execute any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation: (a) to ask for, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, (b) to receive, indorse and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) above, and (c) to file any claims or take any action or institute any proceedings that the Collateral Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral. Section 10. Collateral Agent May Perform. If the Grantor fails to perform any agreement contained herein, the Collateral Agent may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the reasonable expenses of the Collateral Agent incurred in connection therewith shall be payable by the Grantor under Section 13. Section 11. The Collateral Agent's Duties. (a) The powers conferred on the Collateral Agent hereunder are solely to protect the Secured Parties' interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property. CERC - Pledge Agreement

9 (b) Anything contained herein to the contrary notwithstanding, the Collateral Agent may from time to time, when the Collateral Agent deems it to be necessary with (so long as an Event of Default has not occurred and is continuing) the written concurrence of the Grantor, appoint one or more subagents (each a "SUBAGENT") for the Collateral Agent hereunder with respect to all or any part of the Collateral. In the event that the Collateral Agent so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by the Grantor hereunder shall be deemed for purposes of this Pledge Agreement to have been made to such Subagent, in addition to the Collateral Agent, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of the Grantor, (ii) such Subagent shall automatically be vested, in addition to the Collateral Agent, with all rights, powers, privileges, interests and remedies of the Collateral Agent hereunder with respect to such Collateral, and (iii) the term "Collateral Agent," when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Agent with respect to such Collateral, shall include such Subagent; provided, however, that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Collateral Agent. Section 12. Remedies. If any Event of Default shall have occurred and be continuing: (a) The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may: (i) require the Grantor to, and the Grantor hereby agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place and time to be designated by the Collateral Agent that is reasonably convenient to both parties; (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable; and (iii) exercise any and all rights and remedies of any of the Grantor under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, (A) rights of the Grantor to demand or otherwise require payment of any amount with respect to the Collateral and (B) exercise all other rights and remedies with respect to the Collateral. The Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days' notice to the Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. (b) Any cash held by or on behalf of the Collateral Agent and all cash proceeds received by or on behalf of the Collateral Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the CERC - Pledge Agreement

10 discretion of the Collateral Agent, be held by the Collateral Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Agent pursuant to Section 13) in whole or in part by the Collateral Agent for the ratable benefit of the Secured Parties against, all or any part of the Secured Obligations, in the following manner: (i) first, paid to the Agents for any amounts then owing to the Agents pursuant to Section 8.04 of each of the Credit Agreements or otherwise under the Loan Documents, ratably in accordance with such respective amounts then owing to the Agents; and (ii) second, paid to the Lenders for any amounts then owing to them, in their capacities as such, under the Loan Documents ratably in accordance with such respective amounts then owing to such Lenders. Any surplus of such cash or cash proceeds held by or on the behalf of the Collateral Agent and remaining after payment in full of all the Secured Obligations shall be paid over to the Grantor or to whomsoever may be lawfully entitled to receive such surplus. (c) All payments received by the Grantor in respect of the Collateral shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of the Grantor and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary indorsement). (d) The Collateral Agent may, without notice to the Grantor except as required by law and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Secured Obligations against any funds held in any deposit account. Section 13. Indemnity and Expenses. (a) The Grantor agrees to indemnify, defend and save and hold harmless each Secured Party and each of their Affiliates and their respective officers, directors, employees, agents and advisors (each, an "INDEMNIFIED PARTY") from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement (including, without limitation, enforcement of this Agreement), except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party's gross negligence or willful misconduct. (b) The Grantor will upon demand pay to the Collateral Agent the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Collateral Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral, (iii) the exercise or enforcement of any of the rights of the Collateral Agent or the other Secured Parties hereunder or (iv) the failure by the Grantor to perform or observe any of the provisions hereof.

EXHIBIT 99.3 ITEM 1. BUSINESS ENVIRONMENTAL MATTERS GENERAL ENVIRONMENTAL ISSUES We are subject to numerous federal, state and local requirements relating to the protection of the environment and the safety and health of personnel and the public. These requirements relate to a broad range of our activities, including the discharge of pollutants into air, water, and soil; the proper handling of solid, hazardous and toxic materials; and waste, noise, and safety and health standards applicable to the workplace. In order to comply with these requirements, we will spend substantial amounts from time to time to construct, modify and retrofit equipment, acquire air emission allowances for operation of our facilities, and to clean up or decommission disposal or fuel storage areas and other locations as necessary. If we do not comply with environmental requirements that apply to our operations, regulatory agencies could seek to impose on us civil, administrative and/or criminal liabilities as well as seek to curtail our operations. Under some statutes, private parties could also seek to impose upon us civil fines or liabilities for property damage, personal injury and possibly other costs. Under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA, owners and operators of facilities from which there has been a release or threatened release of hazardous substances, together with those who have transported or arranged for the disposal of those substances, are liable for: - the costs of responding to that release or threatened release; and - the restoration of natural resources damaged by any such release. We are not aware of any liabilities under CERCLA that would have a material adverse effect on us, our financial position, results of operations or cash flows. AIR EMISSIONS As part of the 1990 amendments to the Federal Clean Air Act, requirements and schedules for compliance were developed for attainment of health-based standards. As part of this process, standards for NOx emissions, a product of the combustion process associated with power generation and natural gas compression, are being developed or have been finalized. The Texas Commission on Environmental Quality standards require reduction of emissions from Texas Genco's power generating units and some of our natural gas compression facilities. As of December 31, 2002, Texas Genco had invested $551 million for NOx emission controls, and it is planning to make expenditures of at least $131 million in the years 2003 through 2005, with possible additional expenditures after 2005. NOx control estimates for 2006 and 2007 have not been finalized. The Texas Utility Commission has initially approved Texas Genco's NOx emission reduction plan in the amount of $699 million as the most cost-effective alternative in achieving compliance with applicable air quality standards for these generation facilities. Texas Genco is required to fund NOx reduction projects for pipelines in East Texas at a cost of $16.2 million, which is included in the amounts described above. The Environmental Protection Agency (EPA) has announced its determination to regulate hazardous air pollutants, including mercury, from coal-fired and oil-fired steam electric generating units under Section 112 of the Clean Air Act. The EPA plans to develop Maximum Achievable Control Technology (MACT) standards for these types of units as well as for turbines, engines and industrial boilers. The rulemaking for coal and oil-fired steam electric generating units must be completed by December 2004. Compliance with the rules will be required within three years thereafter. The MACT standards that will be applicable to the Texas Genco units cannot be predicted at this time and may adversely impact Texas Genco's operations. The rulemaking for turbines is expected to be complete in August 2003, and for engines and industrial boilers in early February 2004. Based on the rules currently proposed, management does not anticipate a materially adverse impact in interstate pipeline operations or Texas Genco's operations. In 1998, the United States became a signatory to the United Nations Framework Convention on Climate Change (Kyoto Protocol). The Kyoto Protocol calls for developed nations to reduce their emissions of greenhouse gases. Carbon dioxide, which is a major byproduct of the combustion of fossil fuel, is considered to be a greenhouse gas. In 2002, President Bush withdrew the United States' support for the Kyoto Protocol. Since this withdrawal, Congress has explored a number of other alternatives for regulating domestic greenhouse gas emissions. If the country re-enters and the United States Senate ultimately ratifies the Kyoto Protocol and/or if the United States Congress adopts other measures for the control of greenhouse gases, any resulting limitations on power plant carbon dioxide emissions could have a material adverse impact on all fossil fuel-fired electric generating facilities, including those belonging to Texas Genco. The EPA is conducting a nationwide investigation regarding the historical compliance of coal-fueled electric generating stations with various permitting requirements of the Clean Air Act. Specifically, the EPA and the United States Department of Justice have initiated formal enforcement actions and litigation against 1

several other utility companies that operate these stations, alleging that these companies modified their facilities without proper pre-construction permit authority. To date, Texas Genco has not received requests for information related to work activities conducted at its facilities. The EPA has not filed an enforcement action or initiated litigation in connection with Texas Genco facilities. Nevertheless, any litigation, if pursued successfully by the EPA, could accelerate the timing of emission reductions currently contemplated for the facilities and result in the imposition of penalties. In February 2001, the United States Supreme Court upheld previously adopted EPA ambient air quality standards for fine particulate matter and ozone. While attaining these new standards may ultimately require expenditures for air quality control system upgrades for our facilities, regulations establishing required controls are not expected until after 2005. Consequently, it is not possible to determine the impact on our operations at this time. In July 2002, the White House sent to Congress a bill proposing the Clear Skies Act of 2002. The Act is designed to achieve long-term reductions of multiple pollutants produced from fossil fuel-fired power plants. The Act targets reductions averaging 70% for sulfur dioxide, NOx and mercury emissions. If approved by the United States Congress, the Act would create a gradually imposed market-based compliance program that would come into effect initially in 2008 with full compliance required by 2018. Fossil fuel-fired power plants owned by companies like Texas Genco would be affected by the adoption of this program, or other legislation currently pending in the United States Congress addressing similar issues. To comply with such programs, Texas Genco and other regulated entities could pursue a variety of strategies including the installation of pollution controls, the purchase of emission allowances or the curtailment of operations. WATER ISSUES In July 2000, the EPA issued final rules for the implementation of the total maximum daily load (TMDL) program. The goal of the TMDL program is to restore waters designated as impaired by identifying and restricting the loading of pollutants contributing to the impairment. While we are not aware of any of our facilities being directly affected by the current TMDL developments, there is the potential that the establishment of TMDLs may eventually result in more stringent discharge limits in our plant discharge permits. Such limits could require our facilities to install additional water treatment facilities or equipment, modify operational practices or implement other water quality improvement measures. In October 2001, the EPA signed a final rule delaying the effective date of the TMDL rule until April 30, 2003. In December 2002, the EPA published a proposed rulemaking that would withdraw the July 2000 rule. In April 2002, the EPA proposed rules under Section 316(b) of the Clean Water Act relating to the design and operation of cooling water intake structures. This proposal is the second of three current phases of rulemaking dealing with Section 316(b) and generally would affect existing facilities that use significant quantities of cooling water. Under the amended court deadline, the EPA is to issue final rules for these Phase II facilities by February 2004. While the requirements of the final rule cannot be predicted at this time, significant capital expenditures by Texas Genco could be required. We anticipate that substantial comments and, if necessary, litigation will be filed by affected parties to attempt to achieve an acceptable final regulation. The EPA and the State of Texas periodically update water quality standards in response to new toxicological data and the development of enhanced analytical techniques that allow lower detection levels. The lowering of water quality criteria for parameters such as arsenic, mercury and selenium could affect generating facility discharge limitations and require our facilities to install additional treatment equipment. LIABILITY FOR PREEXISTING CONDITIONS AND REMEDIATION Asbestos and Other. As a result of their age, many of our facilities contain significant amounts of asbestos insulation, other asbestos-containing materials and lead-based paint. Existing state and federal rules require the proper management and disposal of these potentially toxic materials. We have developed a management plan that includes proper maintenance of existing non-friable asbestos installations, and removal and abatement of asbestos containing materials where necessary because of maintenance, repairs, replacement 2

or damage to the asbestos itself. We have planned for the proper management, abatement and disposal of asbestos and lead-based paint at our facilities. We have been named, along with numerous others, as a defendant in a number of lawsuits filed by a large number of individuals who claim injury due to exposure to asbestos while working at sites along the Texas Gulf Coast. Most of these claimants have been third party workers who participated in construction of various industrial facilities, including power plants, and some of the claimants have worked at locations owned by us. We anticipate that additional claims like those received may be asserted in the future, and we intend to continue our practice of vigorously contesting claims that we do not consider to have merit. Although their ultimate outcome cannot be predicted at this time, we do not believe, based on our experience to date, that these matters, either individually or in the aggregate, will have a material adverse effect on our financial position, results of operations or cash flows. Manufactured Gas Plant Sites. CERC and its predecessors operated manufactured gas plants (MGP) in the past. In Minnesota, remediation has been completed on two sites, other than ongoing monitoring and water treatment. There are five remaining sites in CERC's Minnesota service territory, two of which CERC believes it neither owned or operated, and for which CERC believes it has no liability. At December 31, 2002, CERC had accrued $19 million for remediation of the Minnesota sites. At December 31, 2002, the estimated range of possible remediation costs was $8 million to $44 million based on remediation continuing for 30 to 50 years. The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRP), if any, and the remediation methods used. CERC has an environmental expense tracker mechanism in its rates in Minnesota. CERC has collected $12 million at December 31, 2002 to be used for future environmental remediation. CERC has received notices from the United States Environmental Protection Agency and others regarding its status as a PRP for other sites. Based on current information, the Company has not been able to quantify a range of environmental expenditures for potential remediation expenditures with respect to other MGP sites. Hydrocarbon Contamination. In August 2001, a number of Louisiana residents who live near the Wilcox Aquifer filed suit in the 1st Judicial District Court, Caddo Parish, Louisiana against CERC and others. The suit alleges that CERC and the other defendants allowed or caused hydrocarbon or chemical contamination of the Wilcox Aquifer, which lies beneath property owned or leased by the defendants and is the sole or primary drinking water aquifer in the area. The monetary damages sought are unspecified. In April 2002, a separate suit with identical allegations against the same parties was filed in the same court. Additionally, in January 2003, a third suit with similar allegations was filed against the same parties in the 26th Judicial District Court, Bossier Parish, Louisiana. Mercury Contamination. Like similar companies, our pipeline and natural gas distribution operations have in the past employed elemental mercury in measuring and regulating equipment. It is possible that small amounts of mercury may have been spilled in the course of normal maintenance and replacement operations and that these spills may have contaminated the immediate area around the meters with elemental mercury. We have found this type of contamination in the past, and we have conducted remediation at sites found to be contaminated. Although we are not aware of additional specific sites, it is possible that other contaminated sites may exist and that remediation costs may be incurred for these sites. Although the total amount of these costs cannot be known at this time, based on our experience and that of others in the natural gas industry to date and on the current regulations regarding remediation of these sites, we believe that the cost of any remediation of these sites will not be material to our financial position, results of operations or cash flows. 3

RISK FACTORS RISK FACTORS ASSOCIATED WITH FINANCIAL CONDITION AND OTHER RISKS IF WE ARE UNABLE TO ARRANGE FUTURE FINANCINGS ON ACCEPTABLE TERMS, OUR ABILITY TO FUND FUTURE CAPITAL EXPENDITURES AND REFINANCE EXISTING INDEBTEDNESS COULD BE LIMITED. As a result of several events occurring in 2001 and 2002, including the September 11, 2001 terrorist attacks, the bankruptcy of Enron Corp., the downgrading of our credit ratings and the credit ratings of several energy companies, the general downturn in the utility industry and the unusual volatility in the U.S. financial markets, the availability and cost of capital for our business have been adversely affected. If we are unable to obtain external financing to meet our future capital requirements on terms that are acceptable to us, our financial condition and future results of operations could be materially adversely affected. As of December 31, 2002, we had $11.1 billion of outstanding indebtedness and trust preferred securities, including $1.0 billion of debt that must be refinanced in 2003, after giving effect to the amendment and extension of our $3.85 billion credit facility in February 2003. In addition, the capital constraints currently impacting our businesses may require our future indebtedness to include terms that are more restrictive or burdensome than those of our current indebtedness. These terms may negatively impact our ability to operate our business or severely restrict or prohibit distributions from our subsidiaries. The success of our future financing efforts may depend, at least in part, on: - general economic and capital market conditions; - credit availability from financial institutions and other lenders; - investor confidence in us and the market in which we operate; - maintenance of acceptable credit ratings; - market expectations regarding our future earnings and probable cash flows; - market perceptions of our ability to access capital markets on reasonable terms; - our exposure to Reliant Resources in connection with its indemnification obligations arising in connection with its separation from us; - provisions of relevant tax and securities laws; and - our ability to obtain approval of specific financing transactions under the 1935 Act. As of December 31, 2002, our CenterPoint Houston subsidiary had $1.8 billion of general mortgage bonds outstanding. It may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee. Although approximately $900 million of additional general mortgage bonds could be issued on the basis of property additions as of December 31, 2002, CenterPoint Houston has agreed contractually to limit incremental secured debt to $300 million. In addition, we are contractually prohibited, subject to certain exceptions, from issuing additional first mortgage bonds. Our current credit ratings are discussed in "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources -- Future Sources and Uses of Cash -- Impact on Liquidity of a Downgrade in Credit Ratings" in Item 7 of this report. We cannot assure you that these credit ratings will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency.

RISK FACTORS AFFECTING THE RESULTS OF OUR ELECTRIC TRANSMISSION & DISTRIBUTION BUSINESS CENTERPOINT HOUSTON MAY NOT BE SUCCESSFUL IN RECOVERING THE FULL VALUE OF ITS STRANDED COSTS AND REGULATORY ASSETS RELATED TO GENERATION. CenterPoint Houston is entitled to recover its stranded costs (the excess of regulatory net book value of generation assets, as defined by the Texas electric restructuring law, over the market value of those assets) and its regulatory assets related to generation. CenterPoint Houston expects to make a filing in January 2004 in a true-up proceeding provided for by the Texas electric restructuring law. The purpose of this proceeding will be to quantify and reconcile: - the amount of stranded costs; - differences in the prices achieved in the state mandated auctions of Texas Genco's generation capacity and Texas Utility Commission estimates; - fuel over- or under-recovery; - the "price to beat" clawback; and - other regulatory assets associated with our generation business that were not previously recovered through the issuance of securitization bonds by a subsidiary. CenterPoint Houston will be required to establish and support the amounts of these costs in order to recover them. CenterPoint Houston expects these costs to be substantial. We cannot assure you that CenterPoint Houston will be able to successfully establish and support its estimates of the value of these costs. For more information about the true-up proceeding, please read "Our Business -- Electric Transmission & Distribution -- Stranded Costs and Regulatory Assets Recovery" above and Note 4(a) to our consolidated financial statements. In addition, CenterPoint Houston's $1.3 billion collateralized term loan matures on November 11, 2005 and is expected to be repaid or refinanced with the proceeds from the recovery of these costs. To the extent CenterPoint Houston has not received the proceeds by November 11, 2005, CenterPoint Houston's ability to repay or refinance its $1.3 billion term loan will be adversely affected. CENTERPOINT HOUSTON'S RECEIVABLES ARE CONCENTRATED IN A SMALL NUMBER OF RETAIL ELECTRIC PROVIDERS. CenterPoint Houston's receivables from the distribution of electricity are collected from retail electric providers that supply the electricity CenterPoint Houston distributes to their customers. Currently, CenterPoint Houston does business with approximately 31 retail electric providers. Adverse economic conditions, structural problems in the new ERCOT market or financial difficulties of one or more retail electric providers could impair the ability of these retail providers to pay for CenterPoint Houston's services or could cause them to delay such payments. CenterPoint Houston depends on these retail electric providers to remit payments timely to it. Any delay or default in payment could adversely affect CenterPoint Houston's cash flows, financial condition and results of operations. CenterPoint Houston's receivables balance from retail electric providers at December 31, 2002 was $85 million. Approximately 72% of CenterPoint Houston's receivables from retail electric providers at December 31, 2002 was owed by subsidiaries of Reliant Resources. Our financial condition may be adversely affected if Reliant Resources is unable to meet its obligations to CenterPoint Houston. Reliant Resources, through its subsidiaries, is CenterPoint Houston's largest customer. Pursuant to the Texas electric restructuring law, Reliant Resources may be obligated to make a large "price to beat" clawback payment to CenterPoint Houston in 2004. CenterPoint Houston expects the clawback, if any, to be applied against any stranded cost recovery to which CenterPoint Houston is entitled or, if no stranded costs are recoverable, to be refunded to retail electric providers. Also, as discussed in "Risk Factors Associated with Financial Condition and Other Risks," Reliant Resources is obligated to indemnify CenterPoint Houston for other potential liabilities. Reliant Resources has reported that it is facing large maturities of its debt over the next year and thus its ability to satisfy its obligations to CenterPoint Houston cannot be assured. RATE REGULATION OF CENTERPOINT HOUSTON'S BUSINESS MAY DELAY OR DENY CENTERPOINT HOUSTON'S FULL RECOVERY OF ITS COSTS. CenterPoint Houston's rates are regulated by certain municipalities and the Texas Utility Commission based on an analysis of its invested capital and its expenses incurred in a test year. Thus, the rates CenterPoint Houston is allowed to charge may not match its expenses at any given time. While rate regulation in Texas is premised on providing a reasonable opportunity to recover reasonable and necessary operating expenses and to earn a reasonable return on its invested capital, there can be no assurance that the Texas Utility Commission will judge all of CenterPoint Houston's costs to be reasonable or necessary or that the regulatory process in which rates are determined will always result in rates that will produce full recovery of CenterPoint Houston's costs. 5

CENTERPOINT HOUSTON IS OPERATING IN A RELATIVELY NEW MARKET ENVIRONMENT IN WHICH IT AND OTHERS HAVE LITTLE OPERATING EXPERIENCE. The competitive electric market in Texas became fully operational in January 2002. Neither CenterPoint Houston nor any of the Texas Utility Commission, ERCOT or other market participants has any significant operating history under the market framework created by the Texas electric restructuring law. Some operational difficulties were encountered in the pilot program conducted in 2001 and continue to be experienced now. These difficulties include delays in the switching of some customers from one retail electric provider to another. These difficulties create uncertainty as to the amount of transmission and distribution charges owed by each retail electric provider, which may cause payment of those amounts to be delayed. While to date these difficulties have not been material, these operating difficulties could become material or structural changes adopted to address these difficulties could materially adversely affect its results of operations, financial condition and cash flows. DISRUPTIONS AT POWER GENERATION FACILITIES OWNED BY THIRD PARTIES COULD INTERRUPT CENTERPOINT HOUSTON'S SALES OF TRANSMISSION AND DISTRIBUTION SERVICES. CenterPoint Houston depends on power generation facilities owned by third parties to provide retail electric providers with electric power which it transmits and distributes to their customers. CenterPoint Houston does not own or operate any power generation facilities. If power generation is disrupted or if power generation capacity is inadequate, CenterPoint Houston's transmission and distribution services may be interrupted, and its results of operations, financial condition and cash flows may be adversely affected. CENTERPOINT HOUSTON'S REVENUES AND RESULTS OF OPERATIONS ARE SEASONAL. A portion of CenterPoint Houston's revenues is derived from rates that it collects from each retail electric provider based on the amount of electricity it distributes on behalf of each retail electric provider. Thus, CenterPoint Houston's revenues and results of operations are subject to seasonality, weather conditions and other changes in electricity usage, with revenues being higher during the warmer months. TECHNOLOGICAL CHANGE MAY MAKE ALTERNATIVE ENERGY SOURCES MORE ATTRACTIVE AND MAY ADVERSELY AFFECT CENTERPOINT HOUSTON'S REVENUES AND RESULTS OF OPERATIONS. The continuous process of technological development may result in the introduction to retail customers of economically attractive alternatives to purchasing electricity through CenterPoint Houston's distribution facilities. Manufacturers of self-generation facilities continue to develop smaller-scale, more-fuel-efficient generating units that can be cost-effective options for some retail customers with smaller electric energy requirements. Any reduction in the amount of electric energy CenterPoint Houston distributes as a result of these technologies may have an adverse impact on its results of operations, financial condition and cash flows in the future. RISK FACTORS AFFECTING THE RESULTS OF OUR ELECTRIC GENERATION BUSINESS TEXAS GENCO'S REVENUES AND RESULTS OF OPERATIONS ARE IMPACTED BY MARKET RISKS THAT ARE BEYOND ITS CONTROL. Texas Genco sells electric generation capacity, energy and ancillary services in the ERCOT market. The ERCOT market consists of the majority of the population centers in the State of Texas and represents approximately 85% of the demand for power in the state. Under the Texas electric restructuring law, Texas Genco and other power generators in Texas are not subject to traditional cost-based regulation and, therefore, may sell electric generation capacity, energy and ancillary services to wholesale purchasers at prices determined by the market. As a result, Texas Genco is not guaranteed any rate of return on its capital investments through mandated rates, and its revenues and results of operations depend, in large part, upon prevailing market prices for electricity in the ERCOT market. Market prices for electricity, generation capacity, energy and ancillary services may fluctuate substantially. Texas Genco's gross margins are primarily derived from the sale of capacity entitlements associated with its large, solid fuel base-load generating units, including its Limestone and W. A. Parish facilities and its interest in the South Texas Project. The gross margins generated from payments associated with the capacity of these units are directly impacted by natural gas prices. Since the fuel costs for Texas Genco's base-load units are largely fixed under long-term contracts, they are generally not subject to significant daily and monthly fluctuations. However, the market price for power in the ERCOT market is directly affected by the price of natural gas. Because natural gas is the marginal fuel for facilities serving the ERCOT market during most hours, its price has a significant influence on the price of electric power. As a result, the price customers are willing to pay for entitlements to Texas Genco's solid fuel-fired base-load capacity generally rises and falls with natural gas prices. 6

Market prices in the ERCOT market may also fluctuate substantially due to other factors. Such fluctuations may occur over relatively short periods of time. Volatility in market prices may result from: - oversupply or undersupply of generation capacity; - power transmission or fuel transportation constraints or inefficiencies; - weather conditions; - seasonality; - availability and market prices for natural gas, crude oil and refined products, coal, enriched uranium and uranium fuels; - changes in electricity usage; - additional supplies of electricity from existing competitors or new market entrants as a result of the development of new generation facilities or additional transmission capacity; - illiquidity in the ERCOT market; - availability of competitively priced alternative energy sources; - natural disasters, wars, embargoes, terrorist attacks and other catastrophic events; and - federal and state energy and environmental regulation and legislation. THERE IS CURRENTLY A SURPLUS OF GENERATING CAPACITY IN THE ERCOT MARKET AND WE EXPECT THE MARKET FOR WHOLESALE POWER TO BE HIGHLY COMPETITIVE. The amount by which power generating capacity exceeded peak demand (reserve margin) in the ERCOT market has exceeded 20% since 2001, and the Texas Utility Commission and the ERCOT ISO have forecasted the reserve margin for 2003 to continue to exceed 20%. A market consulting firm specializing in the power industry has published a report that predicts there will be a surplus of generating capacity in the ERCOT market for the next several years. The commencement of commercial operation of new facilities in the ERCOT region will increase the competitiveness of the wholesale power market, which could have a material adverse effect on Texas Genco's results of operations, financial condition, cash flows and the market value of Texas Genco's assets. Texas Genco's competitors include generation companies affiliated with Texas-based utilities, independent power producers, municipal and co-operative generators and wholesale power marketers. The unbundling of vertically integrated utilities into separate generation, transmission and distribution and retail businesses pursuant to the Texas electric restructuring law could result in a significant number of additional competitors participating in the ERCOT market. Some of Texas Genco's competitors may have greater financial resources, lower cost structures, more effective risk management policies and procedures, greater ability to incur losses, greater potential for profitability from ancillary services, and greater flexibility in the timing of their sale of generating capacity and ancillary services than Texas Genco does. TEXAS GENCO IS SUBJECT TO OPERATIONAL AND MARKET RISKS ASSOCIATED WITH ITS CAPACITY AUCTIONS. Texas Genco is obligated to sell substantially all of its capacity and related ancillary services through 2003 pursuant to the capacity auctions more fully described under "Our Business -- Electric Generation" above. In these auctions, Texas Genco sells firm entitlements on a forward basis to capacity and ancillary services dispatched within specified operational constraints. Although Texas Genco has reserved a portion of its aggregate net generation capacity from its capacity auctions for planned or forced outages at its facilities, unanticipated plant outages or other problems with its generation facilities could result in its firm capacity and ancillary services commitments exceeding its available generation capacity. As a result, Texas Genco could be required to obtain replacement power from third parties in the open market to satisfy its firm commitments that could result in significant additional costs. In addition, an unexpected outage at one of Texas Genco's 7

lower cost facilities could require it to run one of its higher cost plants in order to satisfy its obligations even though the energy payments for the dispatched power are based on the cost at the lower-cost facility. Texas Genco sells capacity entitlements in state mandated auctions and in its other contractually mandated auctions. The mechanics, regulations and agreements governing Texas Genco's capacity auctions are complex, and the auction process in which Texas Genco sells entitlements to its capacity is relatively new. The state mandated auctions require, among other things, Texas Genco's capacity entitlements to be sold in pre-determined amounts. The characteristics of the capacity entitlements Texas Genco sells in state mandated auctions are defined by rules adopted by the Texas Utility Commission and, therefore, cannot be changed to respond to market demands or operational requirements without approval by the Texas Utility Commission. IF THE ERCOT MARKET DOES NOT FUNCTION IN THE MANNER CONTEMPLATED BY THE TEXAS ELECTRIC RESTRUCTURING LAW, TEXAS GENCO'S BUSINESS PROSPECTS, RESULTS OF OPERATIONS, FINANCIAL CONDITION AND CASH FLOWS COULD BE ADVERSELY IMPACTED. The initiatives under the Texas electric restructuring law have had a significant impact on the nature of the electric power industry in Texas and the manner in which participants in the ERCOT market conduct their business. These changes are ongoing, and we cannot predict the future development of the ERCOT market or the ultimate effect that this changing regulatory environment will have on Texas Genco's business. Some restructured markets in other states have recently experienced supply problems and extreme price volatility. If the ERCOT market does not function as planned once the deregulation initiatives called for by the Texas electric restructuring law have taken their full effect, Texas Genco's results of operations, financial condition and cash flows could be adversely affected. In addition, any market failures could lead to revisions or reinterpretations of the Texas electric restructuring law, the adoption of new laws and regulations applicable to Texas Genco or its facilities and other future changes in laws and regulations that may have a detrimental effect on Texas Genco's business. As part of the transition to retail competition in Texas, the ERCOT market has changed from operating with multiple control areas, each managed by one of the utilities in the state, to a single control area managed by the ERCOT ISO. The ERCOT ISO is responsible for maintaining reliable operations of the bulk electric power supply system in the new combined control area. If the ERCOT ISO is unable to successfully manage these functions, the ERCOT market may not operate properly and Texas Genco's results of operations could be adversely affected. In addition, the ERCOT ISO may impose or the Texas Utility Commission may require price limitations, bidding rules and other mechanisms that could impact wholesale prices in the ERCOT market and the outcomes of Texas Genco's capacity auctions. THE OPERATION OF TEXAS GENCO'S POWER GENERATION FACILITIES INVOLVES RISKS THAT COULD ADVERSELY AFFECT ITS REVENUES, COSTS, RESULTS OF OPERATIONS, FINANCIAL CONDITION AND CASH FLOWS. Texas Genco is subject to various risks associated with operating its power generation facilities, any of which could adversely affect its revenues, costs, results of operations, financial condition and cash flows. These risks include: - operating performance below expected levels of output or efficiency; - breakdown or failure of equipment or processes; - disruptions in the transmission of electricity; - shortages of equipment, material or labor; - labor disputes; - fuel supply interruptions; - limitations that may be imposed by regulatory requirements, including, among others, environmental standards; - limitations imposed by the ERCOT ISO; 8

- violations of permit limitations; - operator error; and - catastrophic events such as fires, hurricanes, explosions, floods, terrorist attacks or other similar occurrences. A significant portion of Texas Genco's facilities were constructed many years ago. Older generation equipment, even if maintained in accordance with good engineering practices, may require significant capital expenditures to keep it operating at high efficiency and to meet regulatory requirements. This equipment is also likely to require periodic upgrading and improvement. Any unexpected failure to produce power, including failure caused by breakdown or forced outage, could result in reduced earnings. Texas Genco employs experienced personnel to maintain and operate its facilities and carries insurance to mitigate the effects of some of the operating risks described above. Texas Genco's insurance policies, however, are subject to certain limits and deductibles and do not include business interruption coverage. Should one or more of the events described above occur, revenues from Texas Genco's operations may be significantly reduced or its costs of operations may significantly increase. TEXAS GENCO RELIES ON POWER TRANSMISSION FACILITIES THAT IT DOES NOT OWN OR CONTROL AND THAT ARE SUBJECT TO TRANSMISSION CONSTRAINTS WITHIN THE ERCOT MARKET. IF THESE FACILITIES FAIL TO PROVIDE TEXAS GENCO WITH ADEQUATE TRANSMISSION CAPACITY, IT MAY NOT BE ABLE TO DELIVER WHOLESALE ELECTRIC POWER TO ITS CUSTOMERS AND IT MAY INCUR ADDITIONAL COSTS. Texas Genco depends on transmission and distribution facilities owned and operated by our wholly owned subsidiary, CenterPoint Houston, and on transmission and distribution systems owned by others to deliver the wholesale electric power it sells from its power generation facilities to its customers, who in turn deliver power to the end users. If transmission is disrupted, or if transmission capacity infrastructure is inadequate, Texas Genco's ability to sell and deliver wholesale electric energy may be adversely impacted. The single control area of the ERCOT market is currently organized into four congestion zones, referred to as the North, South, West and Houston zones. These congestion zones are determined by physical constraints on the ERCOT transmission system that make it difficult or impossible at times to move power from a zone on one side of the constraint to the zone on the other side of the constraint. All but two of Texas Genco's facilities are located in the Houston congestion zone. Texas Genco's Limestone facility is located in the North congestion zone and the South Texas Project is located in the South congestion zone. Texas Genco sells a portion of the entitlements offered in its state mandated auctions to customers located in congestion zones other than the Houston zone. Transmission congestion between these zones could impair Texas Genco's ability to schedule power for transmission across zonal boundaries, which are defined by the ERCOT ISO, thereby inhibiting its efforts to match its facility scheduled outputs with its customer scheduled requirements. The ERCOT ISO has instituted rules that directly assign congestion costs to the parties causing the congestion. Therefore, power generators participating in the ERCOT market could be liable for the congestion costs associated with transferring power between zones. Texas Genco schedules its anticipated requirements based on its own forecasted needs, which rely in part on demand forecasts made by its customers. These forecasts may prove to be inaccurate. Texas Genco could be deemed responsible for congestion costs if it schedules delivery of power between congestion zones during times when the ERCOT ISO expects congestion to occur between the zones. If Texas Genco is liable for congestion costs, its financial results could be adversely affected. For more information about the ERCOT market, please read "Our Business -- Overview -- ERCOT Market Framework" above. TEXAS GENCO'S RESULTS OF OPERATIONS, FINANCIAL CONDITION AND CASH FLOWS COULD BE ADVERSELY IMPACTED BY A DISRUPTION OF ITS FUEL SUPPLIES. Texas Genco relies primarily on natural gas, coal, lignite and uranium to fuel its generation facilities. Texas Genco purchases its fuel from a number of different suppliers under long-term contracts and on the spot market. Under Texas Genco's capacity auctions, it sells firm entitlements to capacity and ancillary services. 9

Therefore, any disruption in the delivery of fuel could prevent Texas Genco from operating its facilities to meet its auction commitments, which could adversely affect its results of operations, financial condition and cash flows. Delivery of natural gas to each of Texas Genco's natural gas-fired facilities typically depends on the natural gas pipelines or distributors for that location. As a result, Texas Genco is subject to the risk that a natural gas pipeline or distributor may suffer disruptions or curtailments in its ability to deliver natural gas to it or that the amounts of natural gas Texas Genco requests are curtailed. These disruptions or curtailments could adversely affect Texas Genco's ability to operate its natural gas-fired generating facilities. Texas Genco leases gas storage facilities capable of storing approximately 6.3 billion cubic feet of natural gas, of which 4.2 billion cubic feet is working capacity. Texas Genco purchases coal from a limited number of suppliers. Generally, Texas Genco seeks to maintain average coal reserves sufficient to operate its coal-fired facilities for 30 days. Texas Genco also has long-term rail transportation contracts with two rail transportation companies to transport coal to its coal-fired facilities. Any extended disruption in Texas Genco's coal supply, including those caused by transportation disruptions, adverse weather conditions, labor relations or environmental regulations affecting Texas Genco's coal suppliers, could adversely affect its ability to operate its coal-fired facilities. Texas Genco is also exposed to the risk that suppliers that have agreed to provide it with fuel could breach their obligations. Should these suppliers fail to perform, Texas Genco may be forced to enter into alternative arrangements at then-current market prices. As a result, Texas Genco's results of operations, financial condition and cash flows could be adversely affected. TO DATE, TEXAS GENCO HAS SOLD A SUBSTANTIAL PORTION OF ITS AUCTIONED CAPACITY ENTITLEMENTS TO A SINGLE CUSTOMER, RELIANT RESOURCES. ACCORDINGLY, TEXAS GENCO'S RESULTS OF OPERATIONS, FINANCIAL CONDITION AND CASH FLOWS COULD BE ADVERSELY AFFECTED IF RELIANT RESOURCES DECLINED TO PARTICIPATE IN TEXAS GENCO'S FUTURE AUCTIONS OR FAILED TO MAKE PAYMENTS WHEN DUE UNDER RELIANT RESOURCES' PURCHASED ENTITLEMENTS. By participating in Texas Genco's contractually mandated auctions, subsidiaries of Reliant Resources purchased entitlements to 63% of the aggregate 2002 capacity and 58% of the aggregate 2003 capacity that Texas Genco has sold to date through its capacity auctions. Reliant Resources made these purchases either through the exercise of its contractual rights to purchase 50% of the entitlements Texas Genco auctions in its contractually mandated auctions or through the submission of bids. In the event Reliant Resources declined to participate in Texas Genco's future auctions or failed to make payments when due, Texas Genco's results of operations, financial condition and cash flows could be adversely affected. In this regard, Reliant Resources has reported that it is facing large maturities of debt over the next year, and its securities ratings are now below investment grade. TEXAS GENCO MAY INCUR SUBSTANTIAL COSTS AND LIABILITIES AS A RESULT OF ITS OWNERSHIP OF NUCLEAR FACILITIES. Texas Genco owns a 30.8% interest in the South Texas Project, a nuclear powered generation facility. As a result, Texas Genco is subject to risks associated with the ownership and operation of nuclear facilities. These risks include: - the potential harmful effects on the environment and human health resulting from the operation of nuclear facilities and the storage, handling and disposal of radioactive materials; - limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with nuclear operations; and - uncertainties with respect to the technological and financial aspects of decommissioning nuclear plants at the end of their licensed lives. The NRC has broad authority under federal law to impose licensing and safety-related requirements for the operation of nuclear generation facilities. In the event of non-compliance, the NRC has the authority to impose fines, shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Revised safety requirements promulgated by the NRC could necessitate substantial 10

capital expenditures at nuclear plants. In addition, although we have no reason to anticipate a serious nuclear incident at the South Texas Project, if an incident did occur, it could have a material adverse effect on Texas Genco's results of operations, financial condition and cash flows. CONTRACTUAL RESTRICTIONS ON THE OPERATION OF TEXAS GENCO'S BUSINESS MAY LIMIT ITS ABILITY TO TAKE ACTIONS AVAILABLE TO OTHER COMPANIES THAT ARE NOT SUBJECT TO SIMILAR RESTRICTIONS. Effective December 31, 2000, Reliant Resources and Reliant Energy entered into a master separation agreement, that now governs the rights and obligations of us and Reliant Resources in connection with the business separation plan of Reliant Energy adopted in response to the Texas electric restructuring law. Reliant Resources also has an option to purchase the shares of Texas Genco stock owned by us that is exercisable in January 2004. Texas Genco has agreed to comply with certain restrictions governing its operations as contemplated by the master separation agreement and option agreement. These restrictions limit Texas Genco's ability to: - merge or consolidate with another entity; - sell assets; - enter into long-term agreements and commitments for the purchase of fuel or the purchase or sale of power outside the ordinary course of business; - engage in other businesses; - construct or acquire new generation plants or capacity; - engage in hedging transactions; - encumber Texas Genco's assets; - issue additional equity securities; - pay special dividends; and - make certain loans, investments or advances to, or engage in certain transactions with, Texas Genco's affiliates. TEXAS GENCO MAY NOT HAVE ACCESS TO SUFFICIENT CAPITAL IN THE AMOUNTS AND AT THE TIMES NEEDED TO FINANCE ITS BUSINESS. To date, Texas Genco's capital has been provided by internally generated cash flows and borrowings and capital contributions from CenterPoint Energy. We can give no assurances that Texas Genco's current and future capital structure, operating performance, financial condition and cash flows will permit it to access the capital markets or to obtain other financing as needed to meet its working capital requirements and projected future capital expenditures on favorable terms. Texas Genco's projected future capital expenditures are substantial. Texas Genco's ability to secure third party credit lines or other debt financing may be adversely impacted by the factors described in this section, including the nature of its business, which may lead to volatility in its financial results and cash flows. CenterPoint Energy has agreed to lend funds to Texas Genco from time to time upon Texas Genco's request until the earlier of the closing date on which Reliant Resources acquires Texas Genco common stock from CenterPoint Energy pursuant to the Reliant Resources option or the expiration of the Reliant Resources option. In the event CenterPoint Energy were to experience liquidity problems or otherwise failed to perform, Texas Genco may be unable to obtain third party financing. In addition, Texas Genco's ability to raise capital is restricted under its agreements with CenterPoint Energy. These restrictions limit Texas Genco's ability to: - issue additional equity securities; - encumber its assets; or 11

- incur indebtedness, except to satisfy requirements for operating and maintenance expenditures and other capital expenditures contemplated under its agreements with CenterPoint Energy, to meet its working capital needs, or to refinance indebtedness incurred for the foregoing purposes. In connection with CenterPoint Energy's registration as a public utility holding company under the 1935 Act, the SEC has limited the aggregate amount of Texas Genco's external borrowings to $500 million. In addition, the order issued to CenterPoint Energy under the 1935 Act restricts Texas Genco's ability to pay dividends out of capital accounts. Under these restrictions, Texas Genco is permitted to pay dividends out of its current or retained earnings, and it may also pay dividends in an amount of up to $100 million in excess of its current or retained earnings. TEXAS GENCO'S OPERATIONS ARE SUBJECT TO EXTENSIVE REGULATION. IF TEXAS GENCO FAILS TO COMPLY WITH APPLICABLE REGULATIONS OR OBTAIN OR MAINTAIN ANY NECESSARY GOVERNMENTAL PERMIT OR APPROVAL, IT MAY BE SUBJECT TO CIVIL, ADMINISTRATIVE AND/OR CRIMINAL PENALTIES THAT COULD ADVERSELY IMPACT ITS RESULTS OF OPERATIONS, FINANCIAL CONDITION AND CASH FLOWS. Texas Genco's operations are subject to complex and stringent energy, environmental and other governmental laws and regulations. The acquisition, ownership and operation of power generation facilities require numerous permits, approvals and certificates from federal, state and local governmental agencies. These facilities are subject to regulation by the Texas Utility Commission regarding non-rate matters. Existing regulations may be revised or reinterpreted, new laws and regulations may be adopted or become applicable to Texas Genco or any of its generation facilities or future changes in laws and regulations may have a detrimental effect on its business. Operation of the South Texas Project is subject to regulation by the NRC. This regulation involves testing, evaluation and modification of all aspects of plant operation in light of NRC safety and environmental requirements. Continuous demonstrations to the NRC that plant operations meet applicable requirements are also required. The NRC has the ultimate authority to determine whether any nuclear powered generating unit may operate. Water for certain of Texas Genco's facilities is obtained from public water authorities. New or revised interpretations of existing agreements by those authorities or changes in price or availability of water may have a detrimental effect on Texas Genco's business. If Texas Genco fails to comply with regulatory requirements that apply to its operations, regulatory agencies could seek to impose civil, administrative and/or criminal liabilities or could take other actions seeking to curtail its operations. These liabilities or actions could adversely impact its results of operations, financial condition and cash flows. TEXAS GENCO'S COSTS OF COMPLIANCE WITH ENVIRONMENTAL LAWS ARE SIGNIFICANT AND THE COST OF COMPLIANCE WITH NEW ENVIRONMENTAL LAWS AND ITS EXPOSURE TO POTENTIAL LIABILITIES ASSOCIATED WITH THE ENVIRONMENTAL CONDITION OF ITS FACILITIES COULD ADVERSELY AFFECT ITS PROFITABILITY. Texas Genco's business is subject to extensive environmental regulation by federal, state and local authorities. Texas Genco is required to comply with numerous environmental laws and regulations, and to obtain numerous governmental permits, in operating its facilities. Texas Genco may incur significant additional costs to comply with these requirements. If Texas Genco fails to comply with these requirements, it could be subject to civil or criminal liability and fines. Existing environmental regulations could be revised or reinterpreted, new laws and regulations could be adopted or become applicable to Texas Genco or its facilities, and future changes in environmental laws and regulations could occur, including potential regulatory and enforcement developments related to air emissions. If any of these events occurs, Texas Genco's business, results of operations, financial condition and cash flows could be adversely affected. Texas Genco may not be able to obtain or maintain from time to time all required environmental regulatory approvals. If there is a delay in obtaining any required environmental regulatory approvals or if 12

Texas Genco fails to obtain and comply with them, it may not be able to operate its facilities or it may be required to incur additional costs. Texas Genco is generally responsible for all on-site liabilities associated with the environmental condition of its power generation facilities, regardless of when the liabilities arose and whether the liabilities are known or unknown. These liabilities may be substantial. CHANGES IN TECHNOLOGY MAY MAKE TEXAS GENCO'S POWER GENERATION FACILITIES LESS COMPETITIVE, WHICH COULD ADVERSELY IMPACT THEIR VALUE AND THE RESULTS OF TEXAS GENCO'S OPERATIONS. A significant portion of Texas Genco's generation facilities were constructed many years ago and rely on older technologies. Some of Texas Genco's competitors may have newer generation facilities and technologies that allow them to produce and sell power more efficiently, which could adversely affect Texas Genco's results of operations, financial condition and cash flows. In addition, research and development activities are ongoing to improve alternate technologies to produce electricity, including fuel cells, microturbines, windmills and photovoltaic (solar) cells. It is possible that advances in these or other technologies will reduce the current costs of electricity production to a level that is below that of Texas Genco's generation facilities. If this occurs, Texas Genco's generation facilities will be less competitive and the value of its power plants could be significantly impaired. Also, electricity demand could be reduced by increased conservation efforts and advances in technology that could likewise significantly reduce the value of Texas Genco's power generation facilities. RISK FACTORS AFFECTING THE RESULTS OF OUR NATURAL GAS DISTRIBUTION AND PIPELINES AND GATHERING BUSINESSES OUR NATURAL GAS DISTRIBUTION BUSINESS MUST COMPETE WITH ALTERNATIVE ENERGY SOURCES. CERC competes primarily with alternate energy sources such as electricity and other fuel sources. In some areas, intrastate pipelines, other gas distributors and marketers also compete directly with CERC for natural gas sales to end-users. In addition, as a result of federal regulatory changes affecting interstate pipelines, natural gas marketers operating on these pipelines may be able to bypass CERC's facilities and market, sell and/or transport natural gas directly to commercial and industrial customers. Any reduction in the amount of natural gas marketed, sold or transported by CERC as a result of competition may have an adverse impact on CERC's results of operations, financial condition and cash flows. OUR NATURAL GAS DISTRIBUTION BUSINESS IS SUBJECT TO FLUCTUATIONS IN NATURAL GAS PRICING LEVELS. CERC is subject to risk associated with upward price movements of natural gas. High natural gas prices might affect CERC's ability to collect balances due from its customers and could create the potential for uncollectible accounts expense to exceed the recoverable levels built into CERC's tariff rates. In addition, a sustained period of high natural gas prices could apply downward demand pressure on natural gas consumers in CERC's service territory. CERC MAY INCUR CARRYING COSTS ASSOCIATED WITH PASSING THROUGH CHANGES IN THE COSTS OF NATURAL GAS. Generally, the regulations of the states in which CERC operates allow it to pass through changes in the costs of natural gas to its customers through purchased gas adjustment provisions in the applicable tariffs. There is, however, a timing difference between its purchases of natural gas and the ultimate recovery of these costs. Consequently, CERC may incur carrying costs as a result of this timing difference that are not recoverable from its customers. The failure to recover those additional carrying costs may have an adverse effect on CERC's results of operations, financial condition and cash flows. 13

OUR PIPELINES AND GATHERING BUSINESSES MUST COMPETE DIRECTLY WITH OTHERS IN THE TRANSPORTATION AND STORAGE OF NATURAL GAS AND INDIRECTLY WITH ALTERNATIVE FORMS OF ENERGY. Our two interstate pipelines and our gathering systems compete with other interstate and intrastate pipelines and gathering systems in the transportation and storage of natural gas. The principal elements of competition are rates, terms of service, and flexibility and reliability of service. They also compete indirectly with other forms of energy, including electricity, coal and fuel oils. The primary competitive factor is price. The actions of CERC's competitors could lead to lower prices, which may have an adverse impact on CERC's results of operations, financial condition and cash flows. IF WE FAIL TO EXTEND CONTRACTS WITH TWO OF OUR SIGNIFICANT INTERSTATE PIPELINES' CUSTOMERS, IT COULD HAVE AN ADVERSE IMPACT ON CERC'S OPERATIONS. Contracts with two of our interstate pipelines' significant customers, Arkla and Laclede, are currently scheduled to expire in 2005 and 2007, respectively. To the extent the pipelines are unable to extend these contracts or the contracts are renegotiated at rates substantially different than the rates provided in the current contracts, it could have an adverse effect on CERC's results of operations, financial condition and cash flows. OUR INTERSTATE PIPELINES ARE SUBJECT TO FLUCTUATIONS IN THE SUPPLY OF GAS. Our interstate pipelines largely rely on gas sourced in the various supply basins located in the Midcontinent region of the United States. To the extent the availability of this supply is substantially reduced, it could have an adverse effect on CERC's results of operations, financial condition and cash flows. CERC'S REVENUES AND RESULTS OF OPERATIONS ARE SEASONAL. A portion of CERC's revenues are derived from natural gas sales and transportation. Thus, CERC's revenues and results of operations are subject to seasonality, weather conditions and other changes in natural gas usage, with revenues being higher during the winter months. ITEM 3.

CENTERPOINT ENERGY, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (D) LONG-LIVED ASSETS AND INTANGIBLES The Company records property, plant and equipment at historical cost. The Company expenses repair and maintenance costs as incurred. Property, plant and equipment includes the following:

In July 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142), which provides that goodwill and certain intangibles with indefinite lives will not be amortized into results of operations, but instead will be reviewed periodically for impairment and written down and charged to results of operations only in the periods in which the recorded value of goodwill and certain intangibles with indefinite lives is more than its fair value. On January 1, 2002, the Company adopted the provisions of the statement that apply to goodwill and intangible assets acquired prior to June 30, 2001. 3

With the adoption of SFAS No. 142, the Company ceased amortization of goodwill as of January 1, 2002. A reconciliation of previously reported net income and earnings per share to the amounts adjusted for the exclusion of goodwill amortization follows:

YEAR ENDED DECEMBER 31, ------------------------ 2000 2001 2002 ------ ------ ------ (IN MILLIONS, EXCEPT PER SHARE) Reported income from continuing operations before cumulative effect of accounting change.................... $ 243 $ 496 $ 366 Add: Goodwill amortization, net of tax...................... 50 49 -- ----- ----- ----- Adjusted income from continuing operations before cumulative effect of accounting change.................... $ 293 $ 545 $ 366 ===== ===== ===== Basic Earnings Per Share: Reported income from continuing operations before cumulative effect of accounting change.................... $0.85 $1.71 $1.25 Add: Goodwill amortization, net of tax...................... 0.18 0.17 -- ----- ----- ----- Adjusted income from continuing operations before cumulative effect of accounting change.................... $1.03 $1.88 $1.23 ===== ===== ===== Diluted Earnings Per Share: Reported income from continuing operations before cumulative effect of accounting change.................... $0.84 $1.70 $1.22 Add: Goodwill amortization, net of tax...................... 0.18 0.17 -- ----- ----- ----- Adjusted income from continuing operations before cumulative effect of accounting change.................... $1.02 $1.87 $1.22 ===== ===== =====
The components of the Company's other intangible assets consist of the following:
DECEMBER 31, 2001 DECEMBER 31, 2002 ----------------------- ----------------------- CARRYING ACCUMULATED CARRYING ACCUMULATED AMOUNT AMORTIZATION AMOUNT AMORTIZATION -------- ------------ -------- ------------ (IN MILLIONS) Land Use Rights.......................... $59 $(11) $61 $(12) Other.................................... 16 (2) 19 (2) --- ---- --- ---- Total.................................. $75 $(13) $80 $(14) === ==== === ====
The Company recognizes specifically identifiable intangibles, including land use rights and permits, when specific rights and contracts are acquired. The Company has no intangible assets with indefinite lives recorded as of December 31, 2002. The Company amortizes other acquired intangibles on a straight-line basis over the lesser of their contractual or estimated useful lives that range from 40 to 75 years for land rights and 4 to 25 years for other intangibles. 4

Amortization expense for other intangibles for 2000, 2001 and 2002 was $1.3 million, $1.2 million and $1.9 million, respectively. Estimated amortization expense for the five succeeding fiscal years is as follows (in millions):

2003........................................................ $ 2 2004........................................................ 2 2005........................................................ 2 2006........................................................ 2 2007........................................................ 2 --- Total..................................................... $10 ===
Goodwill by reportable business segment is as follows (in millions):
DECEMBER 31, 2001 AND 2002 ------------- Natural Gas Distribution.................................... $1,085 Pipelines and Gathering..................................... 601 Other Operations............................................ 55 ------ Total..................................................... $1,741 ======
The Company completed its review during the second quarter of 2002 pursuant to SFAS No. 142 for its reporting units in the Natural Gas Distribution, Pipelines and Gathering and Other Operations business segments. No impairment was indicated as a result of this assessment. The Company periodically evaluates long-lived assets, including property, plant and equipment, goodwill and specifically identifiable intangibles, when events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted cash flows attributable to the assets, as compared to the carrying value of the assets. An impairment analysis of generating facilities requires estimates of possible future market prices, load growth, competition and many other factors over the lives of the facilities. A resulting impairment loss is highly dependent on these underlying assumptions. During the fourth quarter of 2001, the Reliant Resources Distribution was deemed to be a probable event. As Reliant Resources has an option to purchase the Company's 81% interest in its generation subsidiary, Texas Genco, in 2004 (see Note 4(b)), the Company was required to evaluate Texas Genco's assets for potential impairment in accordance with SFAS No. 121, due to an expected decrease in the number of years the Company expects to hold and operate these assets. As of December 31, 2001, no impairment had been indicated. As a result of the distribution of approximately 19% of Texas Genco's common stock to CenterPoint Energy's shareholders on January 6, 2003, the Company re-evaluated these assets for impairment as of December 31, 2002 in accordance with SFAS No. 144. As of December 31, 2002, no impairment had been indicated. The Company anticipates that future events, such as a change in the estimated holding period of Texas Genco's generation assets, will require the Company to re-evaluate these assets for impairment between now and 2004. If an impairment is indicated, it could be material and will not be fully recoverable through the 2004 true-up proceeding calculations (see Note 4(a)). The Texas electric restructuring law provides the Company recovery of the regulatory book value of its Texas generating assets for the amount the net regulatory book value exceeds the estimated market value. If the Company's 81% interest in Texas Genco is sold to Reliant Resources or to a third party in the future, a loss on sale of these assets, or an impairment of the recorded recoverable electric generation plant mitigation regulatory asset (see Note 3(e)), will occur to the extent the recorded book value of the Texas generating assets exceeds the regulatory book value. As of December 31, 2002, the recorded book value was $649 million in excess of the regulatory book value. This amount declines each year as the recorded book value is depreciated and increases by the amount of capital expenditures. For further discussion of the difference between the regulatory book value and the recorded book value, see Note 4. 5

(E) REGULATORY ASSETS AND LIABILITIES The Company applies the accounting policies established in SFAS No. 71, "Accounting for the Effects of Certain Types of Regulation" (SFAS No. 71) to the accounts of the Electric Transmission & Distribution business segment and the utility operations of the Natural Gas Distribution business segment and to some of the accounts of the Pipelines and Gathering business segment. For information regarding Texas Genco's discontinuance of the application of SFAS No. 71 in 1999 and the effect on its regulatory assets and the Texas electric restructuring law, see Note 4(a). The following is a list of regulatory assets/liabilities reflected on the Company's Consolidated Balance Sheets as of December 31, 2001 and 2002:

DECEMBER 31, ---------------- 2001 2002 ------- ------ (IN MILLIONS) Excess cost over market (ECOM) true-up...................... $ -- $ 697 Recoverable electric generation related regulatory assets, net....................................................... 160 100 Securitized regulatory asset................................ 740 706 Regulatory tax asset, net................................... 111 178 Unamortized loss on reacquired debt......................... 62 58 Recoverable electric generation plant mitigation............ 1,967 2,051 Excess mitigation liability................................. (1,126) (969) Other long-term assets/liabilities.......................... 4 52 ------- ------ Total..................................................... $ 1,918 $2,873 ======= ======
If events were to occur that would make the recovery of these assets and liabilities no longer probable, the Company would be required to write off or write down these regulatory assets and liabilities. In addition, the Company would be required to determine any impairment of the carrying costs of plant and inventory assets. Through December 31, 2001, the Public Utility Commission of Texas (Texas Utility Commission) provided for the recovery of most of the Company's fuel and purchased power costs from customers through a fixed fuel factor included in electric rates. Included in the above table in recoverable electric generation related regulatory assets, net are $126 million and $66 million of net regulatory assets related to the recovery of fuel costs as of December 31, 2001 and 2002, respectively. For additional information regarding CenterPoint Houston's fuel filings, see Note 4(c). Texas Genco sells, through auctions, entitlements to substantially all of its installed electric generation capacity, excluding reserves for planned and forced outages. In September, October and December 2001, and March, July, October and November 2002, Texas Genco conducted auctions as required by the Texas Utility Commission and by the master separation agreement with Reliant Resources. The capacity auctions were consummated at market-based prices that are substantially below the estimate of those prices made by the Texas Utility Commission in the spring of 2001. The Texas electric restructuring law provides for the recovery in a "true-up" proceeding in 2004 of any difference between market power prices and the earlier estimates of those prices by the Texas Utility Commission, using the prices received in the auctions required by the Texas Utility Commission as the measure of market prices (ECOM true-up). In 2002, CenterPoint Energy recorded approximately $697 million in non-cash revenue related to the cost recovery of the difference between the market power prices and the Texas Utility Commission's earlier estimates. For additional information regarding the capacity auctions and the related true-up proceeding, see Note 4(a). In 2001, the Company monetized $738 million of regulatory assets in a securitization financing authorized by the Texas Utility Commission pursuant to the Texas electric restructuring law. The securitized regulatory assets are being amortized ratably as transition charges are collected over the life of the outstanding transition bonds. For additional information regarding the securitization financing, see Note 4(a). For additional information regarding recoverable impaired plant costs and recoverable electric generation related assets and the related amortization during 2000 and 2001, see Notes 3(g) and 4(a). 6

(K) INVESTMENT IN OTHER DEBT AND EQUITY SECURITIES In accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities" (SFAS No. 115), the Company reports "available-for-sale" securities at estimated fair value within other long-term assets in the Company's Consolidated Balance Sheets and any unrealized gain or loss, net of tax, as a separate component of shareholders' equity and accumulated other comprehensive income. In accordance with SFAS No. 115, the Company reports "trading" securities at estimated fair value in the Company's Consolidated Balance Sheets, and any unrealized holding gains and losses are recorded as other income (expense) in the Company's Statements of Consolidated Operations. As of December 31, 2001 and 2002, the Company held debt and equity securities in its nuclear decommissioning trust, which is reported at its fair value of $169 million and $163 million, respectively, in the Company's Consolidated Balance Sheets in other long-term assets. Any unrealized losses or gains are accounted for as a long-term asset/liability as the Company will not benefit from any gains, and losses will be recovered through the rate-making process. As of December 31, 2001 and 2002, the Company held an investment in AOL Time Warner Inc. (AOL TW) common stock (AOL TW Common), which was classified as a "trading" security. For information regarding the Company's investment in AOL TW Common, see Note 7. 7

(4) REGULATORY MATTERS (A) TEXAS ELECTRIC RESTRUCTURING LAW AND DISCONTINUANCE OF SFAS NO. 71 FOR ELECTRIC GENERATION OPERATIONS In June 1999, the Texas legislature adopted the Texas electric restructuring law, which substantially amended the regulatory structure governing electric utilities in Texas in order to allow retail electric competition. Retail pilot projects allowing competition for up to 5% of each utility's load in all customer classes began in the third quarter of 2001, and retail electric competition for all other customers began in January 2002. In preparation for competition, the Company made significant changes in the electric utility operations it conducts through its former electric utility division, Reliant Energy HL&P (now CenterPoint Houston). In addition, the Texas Utility Commission issued a number of new rules and determinations in implementing the Texas electric restructuring law. The Texas electric restructuring law defined the process for competition and created a transition period during which most utility rates were frozen at rates not in excess of their then-current levels. The Texas electric restructuring law provided for utilities to recover their generation related stranded costs and regulatory assets (as defined in the Texas electric restructuring law). Unbundling. As of January 1, 2002, electric utilities in Texas such as CenterPoint Houston unbundled their businesses in order to separate power generation, transmission and distribution, and retail activities into different units. Pursuant to the Texas electric restructuring law, the Company submitted a plan in January 2000 that was later amended and updated to accomplish the required separation (the business separation plan). The transmission and distribution business continues to be subject to cost-of-service rate regulation and is responsible for the delivery of electricity to retail customers. The Company transferred the Texas generation facilities that were formerly part of Reliant Energy HL&P (Texas generation business) to Texas Genco in connection with the Restructuring. As a result of these changes, the Company's Texas generation operations are no longer conducted as part of an integrated utility and comprise a new business segment, Electric Generation. Additionally, these operations will not be part of the Company's business if they are acquired in 2004 by Reliant Resources pursuant to an option agreement described below or they are otherwise sold. Generation. Power generators began selling electric energy to wholesale purchasers, including retail electric providers, at unregulated prices on January 1, 2002. To facilitate a competitive market, each power generation company affiliated with a transmission and distribution utility is required to sell at auction 15% of the output of its installed generating capacity. The first auction was held in September 2001 for power delivered beginning January 1, 2002. This obligation continues until January 1, 2007 unless before that date the Texas Utility Commission determines that at least 40% of the quantity of electric power consumed in 2000 by residential and small commercial load in the electric utility's service area is being served by retail electric providers other than an affiliated or formerly affiliated retail electric provider. Texas Genco plans to auction all of its remaining capacity (less approximately 10% withheld to provide for unforeseen outages) during the time period prior to Reliant Resources' exercise of the Texas Genco Option discussed below. Pursuant to the business separation plan, Reliant Resources is entitled to purchase, at prices established in these auctions, 50% (but no less than 50%) of the remaining capacity, energy and ancillary services auctioned by Texas Genco. Sales to Reliant Resources represented approximately 66% of Texas Genco's total revenues in 2002. 8

Transmission and Distribution Rates. All retail electric providers in CenterPoint Houston's service area pay the same rates and other charges for transmission and distribution services. CenterPoint Houston's distribution rates charged to retail electric providers are generally based on amounts of energy delivered. Transmission rates charged to other distribution companies are based on amounts of energy transmitted under "postage stamp" rates that do not vary with the distance the energy is being transmitted. All distribution companies in ERCOT pay CenterPoint Houston the same rates and other charges for transmission services. The transmission and distribution rates for CenterPoint Houston have been in effect since January 1, 2002, when electric competition began. This regulated delivery charge includes the transmission and distribution rate (which includes costs for nuclear decommissioning and municipal franchise fees), a system benefit fund fee imposed by the Texas electric restructuring law, a transition charge associated with securitization of regulatory assets and an excess mitigation credit imposed by the Texas Utility Commission. Stranded Costs. CenterPoint Houston will be entitled to recover its stranded costs (the excess of net regulatory book value of generation assets (as defined by the Texas electric restructuring law) over the market value of those assets) and its regulatory assets related to generation. The Texas electric restructuring law prescribes specific methods for determining the amount of stranded costs and the details for their recovery. During the transition period to deregulation (the Transition Period), which included 1998 and the first six months of 1999, and extending through the base rate freeze period from July 1999 through 2001, the Texas electric restructuring law provided that earnings above a stated overall annual rate of return on invested capital be used to recover the Company's investment in generation assets (Accelerated Depreciation). In addition, during the Transition Period, the redirection of depreciation expense to generation assets that CenterPoint Houston would otherwise apply to transmission, distribution and general plant assets was permitted for regulatory purposes (Redirected Depreciation). Please read the discussion of the accounting treatment for depreciation for financial reporting purposes below under "-- Accounting." The Company cannot predict the amount, if any, of these costs that may not be recovered. In accordance with the Texas electric restructuring law, beginning on January 1, 2002, and ending December 31, 2003, any difference between market power prices received in the generation capacity auctions mandated by the Texas electric restructuring law and the Texas Utility Commission's earlier estimates of those prices will be included in the 2004 stranded cost true-up proceeding, as further discussed below. This component of the true-up is intended to ensure that neither the customers nor the Company is disadvantaged economically as a result of the two-year transition period by providing this pricing structure. On October 24, 2001, CenterPoint Energy Transition Bond Company, LLC (Bond Company), a Delaware limited liability company and direct wholly owned subsidiary of CenterPoint Houston, issued $749 million aggregate principal amount of its Series 2001-1 Transition Bonds pursuant to a financing order of the Texas Utility Commission. Classes of the bonds have final maturity dates of September 15, 2007, September 15, 2009, September 15, 2011 and September 15, 2015, and bear interest at rates of 3.84%, 4.76%, 5.16% and 5.63%, respectively. Scheduled payments on the bonds are from 2002 through 2013. Net proceeds to the Bond Company from the issuance were $738 million. The Bond Company paid CenterPoint Houston 9

$738 million for the transition property. Proceeds were used for general corporate purposes, including the repayment of indebtedness. The Transition Bonds are secured primarily by the "transition property," which includes the irrevocable right to recover, through non-bypassable transition charges payable by certain retail electric customers, the qualified costs of CenterPoint Houston authorized by the financing order. The holders of the Bond Company's bonds have no recourse to any assets or revenues of CenterPoint Houston, and the creditors of CenterPoint Houston have no recourse to any assets or revenues (including, without limitation, the transition charges) of the Bond Company. CenterPoint Houston has no payment obligations with respect to the Transition Bonds except to remit collections of transition charges as set forth in a servicing agreement between CenterPoint Houston and the Bond Company and in an intercreditor agreement among CenterPoint Houston, the Bond Company and other parties. The non-bypassable transition charges are required by the financing order to be trued-up annually, effective November 1, for the term of the transition charge. CenterPoint Houston filed an annual true-up with the Texas Utility Commission on August 2, 2002 for transition charges that became effective November 1, 2002. Costs associated with nuclear decommissioning will continue to be subject to cost-of-service rate regulation and are included in a charge to transmission and distribution customers. For further discussion of the effect of the business separation plan on funding of the nuclear decommissioning trust fund, see Note 4(b). True-Up Proceeding. The Texas electric restructuring law and current Texas Utility Commission implementation guidance provide for a true-up proceeding to be initiated in or after January 2004. The purpose of the true-up proceeding is to quantify and reconcile the amount of stranded costs, the capacity auction true-up, unreconciled fuel costs (see Note 3(e)), and other regulatory assets associated with CenterPoint Houston's former electric generating operations that were not previously securitized through the Transition Bonds. The 2004 true-up proceeding will result in either additional charges being assessed on or credits being issued to certain retail electric customers. The Company appealed the Texas Utility Commission's true-up rule on the basis that there are no negative stranded costs, that the Company should be allowed to collect interest on stranded costs, and that the premium on the partial stock valuation applies to only the equity of Texas Genco, not equity plus debt. The Texas court of appeals issued a decision on February 6, 2003 upholding the rule in part and reversing in part. The court ruled that there are no negative stranded costs and that the premium on the partial stock valuation applies only to equity. The court upheld the Texas Utility Commission's rule that interest on stranded costs begins upon the date of the final true-up order. On February 21, 2003, the Company filed a motion for rehearing on the issue that interest on amounts determined in the true-up proceeding should accrue from an earlier date . The Company has not accrued interest in its consolidated financial statements, but estimates that interest could be material. If the court of appeals denies the Company's motion, then the Company will have 45 days to appeal to the Texas Supreme Court. The Company has not decided what action, if any, it will take if the motion for rehearing is denied. Accounting. Historically, the Company has applied the accounting policies established in SFAS No. 71. Effective June 30, 1999, the Company applied SFAS No. 101 to Texas Genco. In 1999, the Company evaluated the effects that the Texas electric restructuring law would have on the recovery of its generation related regulatory assets and liabilities. The Company determined that a pre-tax accounting loss of $282 million existed because it believes only the economic value of its generation related regulatory assets (as defined by the Texas electric restructuring law) will be recoverable. Therefore, the Company recorded a $183 million after-tax extraordinary loss in the fourth quarter of 1999. Pursuant to EITF Issue No. 97-4 "Deregulation of the Pricing of Electricity -- Issues Related to the Application of FASB Statements No. 71 and No. 101" (EITF No. 97-4), the remaining recoverable regulatory assets are now 10

associated with the transmission and distribution portion of the Company's electric utility business. For details regarding the Company's regulatory assets, see Note 3(e). At June 30, 1999, the Company performed an impairment test of its previously regulated electric generation assets pursuant to SFAS No. 121 on a plant specific basis. Under SFAS No. 121, an asset is considered impaired, and should be written down to fair value, if the future undiscounted net cash flows expected to be generated by the use of the asset are insufficient to recover the carrying amount of the asset. For assets that are impaired pursuant to SFAS No. 121, the Company determined the fair value for each generating plant by estimating the net present value of future cash flows over the estimated life of each plant. The difference between fair value and net book value was recorded as a reduction in the current book value. The Company determined that $797 million of electric generation assets were impaired in 1999. Of this amount, $745 million related to the South Texas Project and $52 million related to two gas-fired generation plants. The Texas electric restructuring law provides for recovery of this impairment through regulated cash flows during the transition period and through charges to transmission and distribution customers. As such, a regulatory asset was recorded for an amount equal to the impairment loss and was included on the Company's Consolidated Balance Sheets as a regulatory asset. The Company recorded amortization expense related to the recoverable impaired plant costs and other assets created from discontinuing SFAS No. 71 of $221 million during the six months ended December 31, 1999, $329 million in 2000 and $247 million in 2001. The impairment analysis requires estimates of possible future market prices, load growth, competition and many other factors over the lives of the plants. The resulting impairment loss is highly dependent on these underlying assumptions. In addition, after January 10, 2004, CenterPoint Houston must finalize and reconcile stranded costs (as defined by the Texas electric restructuring law) in a filing with the Texas Utility Commission. Any positive difference between the regulatory net book value and the fair market value of the generation assets (as defined by the Texas electric restructuring law) will be collected through future charges. Any overmitigation of stranded costs may be refunded by a reduction in future charges. This final reconciliation allows alternative methods of third party valuation of the fair market value of these assets, including outright sale, stock valuations and asset exchanges. In order to reduce potential exposure to stranded costs related to generation assets, CenterPoint Houston recognized Redirected Depreciation of $195 million and $99 million in 1998 and for the six months ended June 30, 1999, respectively, for regulatory and financial reporting purposes. This redirection was in accordance with the Company's Transition Plan. Subsequent to June 30, 1999, Redirected Depreciation expense could no longer be recorded by the Company's electric generation business for financial reporting purposes as these operations are no longer accounted for under SFAS No. 71. During the six months ended December 31, 1999 and during 2000 and 2001, $99 million, $218 million and $230 million in depreciation expense, respectively, was redirected from transmission and distribution for regulatory and financial reporting purposes and was established as an embedded regulatory asset included in transmission and distribution related plant and equipment balances. As of December 31, 2001, the cumulative amount of Redirected Depreciation for regulatory purposes was $841 million, prior to the effects of the October 3, 2001 order discussed below. Additionally, as allowed by the Texas Utility Commission, in an effort to further reduce potential exposure to stranded costs related to generation assets, CenterPoint Houston recorded Accelerated Depreciation of $194 million and $104 million in 1998 and for the six months ended June 30, 1999, respectively, for regulatory and financial reporting purposes. Accelerated Depreciation expense was recorded in accordance with the Company's Transition Plan during this period. Subsequent to June 30, 1999, Accelerated Depreciation expense could no longer be recorded by the Company's electric generation business for financial reporting purposes, as these operations are no longer accounted for under SFAS No. 71. During the six months ended December 31, 1999 and during 2000 and 2001, $179 million, $385 million and $264 million, respectively, of Accelerated Depreciation was recorded for regulatory reporting purposes, reducing the regulatory book value of the Company's electric generation assets. 11

The Texas Utility Commission issued a final order on October 3, 2001 (October 3, 2001 Order) that established the transmission and distribution utility rates that became effective in January 2002. In this Order, the Texas Utility Commission found that CenterPoint Houston had overmitigated its stranded costs by redirecting transmission and distribution depreciation and by accelerating depreciation of generation assets as provided under the Transition Plan and Texas electric restructuring law. As a result of the October 3, 2001 Order, CenterPoint Houston was required to reverse the $841 million embedded regulatory asset related to Redirected Depreciation, thereby reducing the net book value of transmission and distribution assets. CenterPoint Houston was required to record a regulatory liability of $1.1 billion related to Accelerated Depreciation. The October 3, 2001 Order requires this amount to be refunded through excess mitigation credits to certain retail electric customers during a seven-year period which began in January 2002. As of December 31, 2002, in contemplation of the 2004 true-up proceeding, CenterPoint Houston has recorded a regulatory asset of $2.0 billion representing the estimated future recovery of previously incurred stranded costs, which includes $1.1 billion of previously recorded Accelerated Depreciation plus Redirected Depreciation, both reversed in 2001. Offsetting this regulatory asset is a $969 million regulatory liability to refund the excess mitigation to ratepayers. This estimated recovery is based upon current projections of the market value of the Company's Texas generation assets to be covered by the 2004 true-up proceeding calculations. The regulatory liability reflects a current refund obligation arising from prior mitigation of stranded costs deemed excessive by the Texas Utility Commission. CenterPoint Houston began refunding excess mitigation credits with January 2002 bills. These credits are to be refunded over a seven-year period. Because accounting principles generally accepted in the United States of America require CenterPoint Houston to estimate fair market values in advance of the final reconciliation, the financial impacts of the Texas electric restructuring law with respect to the final determination of stranded costs in the 2004 true-up proceeding are subject to material changes. Factors affecting such changes may include estimation risk, uncertainty of future energy and commodity prices and the economic lives of the plants. If events were to occur that made the recovery of some of the remaining generation related regulatory assets no longer probable, the Company would write off the unrecoverable balance of such assets as a charge against earnings. (B) AGREEMENTS RELATED TO TEXAS GENERATING ASSETS Pursuant to the business separation plan, on January 6, 2003, the Company distributed approximately 19% of Texas Genco's 80 million outstanding shares of common stock to its shareholders in order to establish a public market value for shares of that stock which will be used in 2004 to calculate how much CenterPoint Houston will be able to recover as stranded costs. Reliant Resources has an option to purchase the Company's remaining 81% interest in Texas Genco (Texas Genco Option). The Texas Genco Option may be exercised between January 10, 2004 and January 24, 2004. The per share exercise price under the option will be the average daily closing price on the applicable national exchange for publicly held shares of common stock of Texas Genco for the 30 consecutive trading days with the highest average closing price during the 120 trading days immediately preceding January 10, 2004, plus a control premium, up to a maximum of 10%, to the extent a control premium is included in the valuation determination made by the Texas Utility Commission relating to the market value of Texas Genco's common stock equity. The exercise price is also subject to adjustment based on the difference between the cash dividends paid during the period there is a public ownership interest in Texas Genco and Texas Genco's earnings during that period. Reliant Resources has agreed that if it exercises the Texas Genco Option and purchases the shares of Texas Genco common stock, Reliant Resources will also purchase all notes and other receivables from Texas Genco then held by CenterPoint Energy, at their principal amount plus accrued interest. Similarly, if Texas Genco holds notes or receivables from the Company, Reliant Resources will assume those obligations in exchange for a payment to Reliant Resources by the Company of an amount equal to the principal plus accrued interest. Exercise of the Texas Genco Option by Reliant Resources will be subject to various regulatory approvals, including Hart-Scott-Rodino antitrust clearance and United States Nuclear Regulatory Commission (NRC) license transfer approval. 12

Texas Genco is the beneficiary of the decommissioning trust that has been established to provide funding for decontamination and decommissioning of a nuclear electric generation station in which Texas Genco owns a 30.8% interest (see Note 6). CenterPoint Houston collects through rates or other authorized charges to its electric utility customers amounts designated for funding the decommissioning trust, and pays the amounts to Texas Genco. Texas Genco in turn deposits these amounts into the decommissioning trust. Upon decommissioning of the facility, in the event funds from the trust are inadequate, CenterPoint Houston or its successor will be required to collect through rates or other authorized charges to customers as contemplated by the Texas Utilities Code all additional amounts required to fund Texas Genco's obligations relating to the decommissioning of the facility. Following the completion of the decommissioning, if surplus funds remain in the decommissioning trust, the excess will be refunded to the ratepayers of CenterPoint Houston or its successor. (C) CENTERPOINT HOUSTON REGULATORY FILINGS CenterPoint Houston and Texas Genco filed their joint application to reconcile fuel revenues and expenses with the Texas Utility Commission on July 1, 2002. This final fuel reconciliation filing covers reconcilable fuel revenue, fuel expense and interest of approximately $8.5 billion incurred from August 1, 1997 through January 30, 2002. Also included in this amount is an under-recovery of $94 million, which was the balance at July 31, 1997 as approved in CenterPoint Houston's last fuel reconciliation. On January 28, 2003, a settlement agreement was reached under which it was agreed that certain items totaling $24 million were written off during the fourth quarter of 2002 and items totaling $203 million will be carried forward for resolution by the Texas Utility Commission in late 2003 or early 2004. (D) ARKLA RATE CASE In November 2001, CenterPoint Energy Arkla (Arkla) filed a rate request in Arkansas seeking rates to yield approximately $47 million in additional annual gross revenue. In August 2002, a settlement was approved by the Arkansas Public Service Commission (APSC) that is expected to result in an increase in base rates of approximately $32 million annually. In addition, the APSC approved a gas main replacement surcharge that is expected to provide $2 million of additional gross revenue in 2003 and additional amounts in subsequent years. The new rates included in the final settlement were effective with all bills rendered on and after September 21, 2002. (E) OKLAHOMA RATE CASE In May 2002, Arkla filed a request in Oklahoma to increase its base rates by $13.7 million annually. In December 2002, a settlement was approved by the Oklahoma Corporation Commission that is expected to result in an increase in base rates of approximately $7.3 million annually. The new rates included in the final settlement were effective with all bills rendered on and after December 29, 2002. (5) DERIVATIVE INSTRUMENTS Effective January 1, 2001, the Company adopted SFAS No. 133, which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. This statement requires that derivatives be recognized at fair value in the balance sheet and that changes in fair value be recognized either currently in earnings or deferred as a component of other comprehensive income, depending on the intended use of the derivative instrument as hedging (a) the exposure to changes in the fair value of an asset or liability (Fair Value Hedge) or (b) the exposure to variability in expected future cash flows (Cash Flow Hedge) or (c) the foreign currency exposure of a net investment in a foreign operation. For a derivative not designated as a hedging instrument, the gain or loss is recognized in earnings in the period it occurs. 13

Adoption of SFAS No. 133 on January 1, 2001 resulted in an after-tax increase in net income of $59 million and a cumulative after-tax increase in accumulated other comprehensive income of $38 million. The adoption also increased current assets, long-term assets, current liabilities and long-term liabilities by approximately $88 million, $5 million, $53 million and $2 million, respectively, in the Company's Consolidated Balance Sheet. The Company is exposed to various market risks. These risks arise from transactions entered into in the normal course of business. The Company utilizes derivative financial instruments such as physical forward contracts, swaps and options (Energy Derivatives) to mitigate the impact of changes and cash flows of its natural gas businesses on its operating results and cash flows. (A) NON-TRADING ACTIVITIES. Cash Flow Hedges. To reduce the risk from market fluctuations associated with purchased gas costs, the Company enters into energy derivatives in order to hedge certain expected purchases and sales of natural gas (non-trading energy derivatives). The Company applies hedge accounting for its non-trading energy derivatives utilized in non-trading activities only if there is a high correlation between price movements in the derivative and the item designated as being hedged. The Company analyzes its physical transaction portfolio to determine its net exposure by delivery location and delivery period. Because the Company's physical transactions with similar delivery locations and periods are highly correlated and share similar risk exposures, the Company facilitates hedging for customers by aggregating physical transactions and subsequently entering into non-trading energy derivatives to mitigate exposures created by the physical positions. During 2002, no hedge ineffectiveness was recognized in earnings from derivatives that are designated and qualify as Cash Flow Hedges. No component of the derivative instruments' gain or loss was excluded from the assessment of effectiveness. If it becomes probable that an anticipated transaction will not occur, the Company realizes in net income the deferred gains and losses recognized in accumulated other comprehensive loss. During the year ended December 31, 2002, there was a $0.9 million deferred loss recognized in earnings as a result of the discontinuance of cash flow hedges because it was no longer probable that the forecasted transaction would occur. Once the anticipated transaction occurs, the accumulated deferred gain or loss recognized in accumulated other comprehensive loss is reclassified and included in the Company's Statements of Consolidated Operations under the caption "Natural Gas and Purchased Power." Cash flows resulting from these transactions in non-trading energy derivatives are included in the Statements of Consolidated Cash Flows in the same category as the item being hedged. As of December 31, 2002, the Company expects $1 million in accumulated other comprehensive loss to be reclassified into net income during the next twelve months. The maximum length of time the Company is hedging its exposure to the variability in future cash flows for forecasted transactions on existing financial instruments is primarily two years with a limited amount of exposure up to five years. The Company's policy is not to exceed five years in hedging its exposure. Interest Rate Swaps. As of December 31, 2002, the Company had outstanding interest rate swaps with an aggregate notional amount of $750 million to fix the interest rate applicable to floating rate short-term debt. These swaps do not qualify as cash flow hedges under SFAS No. 133, and are marked to market in the Company's Consolidated Balance Sheets with changes reflected in interest expense in the Statements of Consolidated Operations. During the year ended December 31, 2002, the Company settled its forward-starting interest rate swaps having an aggregate notional amount of $1.5 billion at a cost of $156 million. The Company has designated and accounted for the forward-interest rate swaps as a cash flow hedge of the Company's exposure to variability in future interest payments on fixed rate debt the Company anticipates issuing. Accordingly, the Company recorded the $156 million cost in other comprehensive income, which will be amortized into interest expense in the same period during which the forecasted interest payments affect earnings. The Company assesses and measures the hedging relationship on a quarterly basis by comparing the 14

critical terms of the forward starting interest rate swaps with the expected terms of the forecasted debt issuance as well as evaluating the probability of the underlying interest payments occurring. The Company reclassified approximately $36 million in 2002 as a result of interest payments it believes are no longer probable of occurring for certain periods. (B) CREDIT RISKS. In addition to the risk associated with price movements, credit risk is also inherent in the Company's non-trading derivative activities. Credit risk relates to the risk of loss resulting from non-performance of contractual obligations by a counterparty. The following table shows the composition of the non-trading derivative assets of the Company as of December 31, 2001 and 2002:

DECEMBER 31, 2001 DECEMBER 31, 2002 ------------------- ----------------------- INVESTMENT INVESTMENT NON-TRADING DERIVATIVE ASSETS GRADE(1)(2) TOTAL GRADE(1)(2) TOTAL (3) - ----------------------------- ----------- ----- ----------- --------- (IN MILLIONS) Energy marketers..................................... $ 9 $ 9 $ 7 $22 Financial institutions............................... -- -- 9 9 --- --- --- --- Total.............................................. $ 9 $ 9 $16 $31 === === === ===
- --------------- (1) "Investment Grade" is primarily determined using publicly available credit ratings along with the consideration of credit support (such as parent company guarantees) and collateral, which encompass cash and standby letters of credit. (2) For unrated counterparties, the Company performs financial statement analysis, considering contractual rights and restrictions and collateral, to create a synthetic credit rating. (3) The $22 million non-trading derivative asset includes a $15 million asset due to trades with Reliant Energy Services, Inc. (Reliant Energy Services) an affiliate until the date of the Reliant Resources Distribution. As of December 31, 2002, Reliant Energy Services did not have an Investment Grade rating. (C) GENERAL POLICY. The Company has established a Risk Oversight Committee comprised of corporate and business segment officers that oversees all commodity price and credit risk activities, including the Company's trading, marketing, risk management services and hedging activities. The committee's duties are to establish the Company's commodity risk policies, allocate risk capital within limits established by the Company's board of directors, approve trading of new products and commodities, monitor risk positions and ensure compliance with the Company's risk management policies and procedures and trading limits established by the Company's board of directors. The Company's policies prohibit the use of leveraged financial instruments. A leveraged financial instrument, for this purpose, is a transaction involving a derivative whose financial impact will be based on an amount other than the notional amount or volume of the instrument. 15

(7) INDEXED DEBT SECURITIES (ACES AND ZENS) AND AOL TIME WARNER SECURITIES (A) ORIGINAL INVESTMENT IN TIME WARNER SECURITIES In 1995, the Company sold a cable television subsidiary to Time Warner Inc.(TW) and received TW convertible preferred stock (TW Preferred) as consideration. On July 6, 1999, the Company converted its 11 million shares of TW Preferred into 45.8 million shares of Time Warner common stock (TW Common). Prior to the conversion, the Company's investment in the TW Preferred was accounted for under the cost method at a value of $990 million in the Company's Consolidated Balance Sheets. The TW Preferred which was redeemable after July 6, 2000, had an aggregate liquidation preference of $100 per share (plus accrued and unpaid dividends), was entitled to annual dividends of $3.75 per share until July 6, 1999 and was convertible by the Company. Effective on the conversion date, the shares of TW Common were classified as trading securities under SFAS No. 115 and an unrealized gain was recorded in the amount of $2.4 billion ($1.5 billion after-tax) to reflect the cumulative appreciation in the fair value of the Company's investment in Time Warner securities. Unrealized gains and losses resulting from changes in the market value of the TW Common (now AOL TW Common) are recorded in the Company's Statements of Consolidated Operations. (B) ACES In July 1997, in order to monetize a portion of the cash value of its investment in TW Preferred, the Company issued 22.9 million of its unsecured 7% Automatic Common Exchange Securities (ACES) having an original principal amount of $1.052 billion and maturing July 1, 2000. The market value of ACES was indexed to the market value of TW Common. On the July 1, 2000 maturity date, the Company tendered 37.9 million shares of TW Common to fully settle its obligations in connection with its unsecured 7% ACES having a value of $2.9 billion. (C) ZENS On September 21, 1999, the Company issued approximately 17.2 million of its 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (ZENS) having an original principal amount of $1.0 billion. The principal amount per ZENS will increase each quarter to the extent that the sum of the quarterly cash dividends and the interest paid during a quarter on the reference shares attributable to one ZENS is less than $.045, so that the annual yield to investors is not less than 2.309%. At December 31, 2002, 14.4 million ZENS were outstanding. At maturity the holders of the ZENS will receive in cash the higher of the original principal amount of the ZENS (subject to adjustment as discussed above) or an amount based on the then-current market value of AOL TW Common, or other securities distributed with respect to AOL TW Common 16

(1.5 shares of AOL TW Common and such other securities, if any, are referred to as reference shares). Each ZENS has a principal amount of $58.25, and is exchangeable at any time at the option of the holder for cash equal to 95% (100% in some cases) of the market value of the reference shares attributable to one ZENS. The Company pays interest on each ZENS at an annual rate of 2% plus the amount of any quarterly cash dividends paid in respect of the quarterly interest period on the reference shares attributable to each ZENS. Subject to some conditions, the Company has the right to defer interest payments from time to time on the ZENS for up to 20 consecutive quarterly periods. As of December 31, 2002, no interest payments on the ZENS had been deferred. In 2002, holders of approximately 16% of the 17.2 million ZENS originally issued exercised their right to exchange their ZENS for cash, resulting in aggregate cash payments by CenterPoint Energy of approximately $45 million. A subsidiary of the Company owns shares of AOL TW Common and elected to liquidate a portion of such holdings to facilitate the Company's making the cash payments for the ZENS exchanged in 2002. In connection with the exchanges in 2002, the Company received net proceeds of approximately $43 million from the liquidation of approximately 4.1 million shares of AOL TW Common at an average price of $10.56 per share. The Company now holds 21.6 million shares of AOL TW Common which are classified as trading securities under SFAS No. 115 and are expected to be held to facilitate the Company's ability to meet its obligation under the ZENS. Prior to January 1, 2001, an increase in the market value per share of TW Common above $58.25 (subject to some adjustments) resulted in an increase in the Company's liability for the ZENS. However, as the market value per share of TW Common declined below $58.25 (subject to some adjustments), the liability for the ZENS did not decline below the original principal amount. Upon adoption of SFAS No. 133 effective January 1, 2001, the ZENS obligation was bifurcated into a debt component and a derivative component (the holder's option to receive the appreciated value of AOL TW Common at maturity). The derivative component was valued at fair value and determined the initial carrying value assigned to the debt component ($121 million) as the difference between the original principal amount of the ZENS ($1.0 billion) and the fair value of the derivative component at issuance ($879 million). Effective January 1, 2001 the debt component was recorded at its accreted amount of $122 million and the derivative component was recorded at its fair value of $788 million, as a current liability, resulting in a transition adjustment pre-tax gain of $90 million ($59 million net of tax). The transition adjustment gain was reported in the first quarter of 2001 as the effect of a change in accounting principle. Subsequently, the debt component accretes through interest charges at 17.5% annually up to the minimum amount payable upon maturity of the ZENS in 2029 (approximately $915 million) which reflects exchanges and adjustments to maintain a 2.309% annual yield, as discussed above. Changes in the fair value of the derivative component are recorded in the Company's Statements of Consolidated Operations. During 2001 and 2002, the Company recorded a loss of $70 million and $500 million, respectively, on the Company's investment in AOL TW Common. During 2001 and 2002, the Company recorded a gain of $58 million and $480 million, respectively, associated with the fair value of the derivative component of the ZENS obligation. Changes in the fair value of the AOL TW Common held by the Company are expected to substantially offset changes in the fair value of the derivative component of the ZENS. 17

The following table sets forth summarized financial information regarding the Company's investment in AOL TW securities and the Company's ACES and ZENS obligations (in millions).

- --------------- (1) Includes amounts due or exchangeable within one year of the date noted. (2) In the first quarter of 2002, CERC reduced its trade receivables facility from $350 million to $150 million. Advances under the receivables facility aggregating $196 million were repaid in January 2002 with proceeds from the issuance of commercial paper and from the liquidation of short-term investments. For further discussion of the receivables facility, see Note 3(i). (3) The $391 million of other short-term borrowings at December 31, 2001 reflects a note payable to Reliant Resources, which was repaid in 2002. (4) Upon adoption of SFAS No. 133 effective January 1, 2001, the Company's ZENS obligation was bifurcated into a debt component and an embedded derivative component. For additional information regarding ZENS, see Note 7(c). As ZENS are exchangeable for cash at any time at the option of the holders, these notes are classified as a current portion of long-term debt. (5) These series of debt are secured by first mortgage bonds of CenterPoint Houston. (6) $527 million of these series of debt is secured by general mortgage bonds of CenterPoint Houston. (7) On February 28, 2003, CenterPoint Energy amended and extended the termination date of its $3.85 billion credit facility to June 30, 2005 as discussed further below. As a result of this extension, the $3.85 billion credit facility has been classified as long-term debt as of December 31, 2002 in the Consolidated Balance Sheet. (8) The December 31, 2001 debt balances have been reclassified to give effect to the Restructuring, which occurred on August 31, 2002. (9) For further discussion of the securitization financing, see Note 4(a). (10) London inter-bank offered rate (LIBOR) has a minimum rate of 3%. This term loan is secured by general mortgage bonds of CenterPoint Houston. (11) Debt acquired in business acquisitions is adjusted to fair market value as of the acquisition date. Included in long-term debt is additional unamortized premium related to fair value adjustments of long-term debt of $9 million and $7 million at December 31, 2001 and 2002, respectively, which is being amortized over the respective remaining term of the related long-term debt. During 2002, the Company recorded a $26 million loss on the early extinguishment of debt related to CenterPoint Houston's $850 million term loan and the repurchase of $175 million of the Company's pollution control bonds. (b) LONG-TERM DEBT On February 28, 2003, the Company reached agreement with a syndicate of banks on a second amendment to its $3.85 billion bank facility (the "Second Amendment"). Under the Second Amendment, the maturity date of the bank facility was extended from October 2003 to June 30, 2005, and the $1.2 billion in mandatory prepayments that would have been required this year (including $600 million due on February 28, 2003) were eliminated. The facility consists of a $2.35 billion term loan and a $1.5 billion revolver. Borrowings bear interest based on LIBOR rates under a pricing grid tied to the Company's credit rating. At our current credit ratings, the pricing for loans remains the same. The drawn cost for the facility at our current ratings is LIBOR plus 450 basis points. The Company has agreed to pay the banks an extension fee of 75 basis points on the amounts outstanding under the bank facility on October 9, 2003. The Company also paid $41 million in fees that were due on February 28, 2003, along with $20 million in fees that had been due on June 30, 2003. In addition, the interest rates will be increased by 25 basis points beginning May 28, 2003 if the Company does not grant the banks a security interest in our 81% stock ownership of Texas Genco. Granting the security interest in the stock of Texas Genco requires approval from the Securities and Exchange Commission (SEC) under the 1935 Act, which is currently being sought. That security interest would be released when the Company sells Texas Genco, which is expected to occur in 2004. Proceeds from the sale will be used to reduce the bank facility. Also under the Second Amendment, on or before May 28, 2003, the Company expects to grant to the banks warrants to purchase up to 10%, on a fully diluted basis, of our common stock at a price equal to the greater of $6.56 per share or 110% of the closing price on the New York Stock Exchange on the date the warrants are issued. The warrants would not be exercisable for a year after issuance but would remain outstanding for four years; provided, that if the Company reduces the bank facility during 2003 by specified amounts, the warrants will be extinguished. To the extent that the Company reduces the bank facility by up to 18

$400 million on or before May 28, 2003, up to half of the warrants will be extinguished on a basis proportionate to the reduction in the credit facility. To the extent such warrants are not extinguished on or before May 28, 2003, they will vest and become exercisable in accordance with their terms. Whether or not the Company is able to extinguish warrants on or before May 28, 2003, the remaining 50% of the warrants will be extinguished, again on a proportionate basis, if the Company reduces the bank facility by up to $400 million by the end of 2003. The Company plans to eliminate the warrants entirely before they vest by accessing the capital markets to fund the total payments of $800 million during 2003; however, because of current financial market conditions and uncertainties regarding such conditions over the balance of the year, there can be no assurance that the Company will be able to extinguish the warrants or to do so on favorable terms. The warrants and the underlying common stock would be registered with the SEC and could be exercised either through the payment of the purchase price or on a "cashless" basis under which the Company would issue a number of shares equal to the difference between the then-current market price and the warrant exercise price. Issuance of the warrants is also subject to obtaining SEC approval under the 1935 Act, which is currently being sought. If that approval is not obtained on or before May 28, 2003, the Company will provide the banks equivalent cash compensation over the term that its warrants would have been exercisable to the extent they are not otherwise extinguished. In the Second Amendment, the Company also agreed that its quarterly common stock dividend will not exceed $0.10 per share. If the Company has not reduced the bank facility by a total of at least $400 million by the end of 2003, of which at least $200 million has come from the issuance of capital stock or securities linked to capital stock (such as convertible debt), the maximum dividend payable during 2004 and for the balance of the term of the facility is subject to an additional test. Under that test the maximum permitted quarterly dividend will be the lesser of (i) $0.10 per share or (ii) 12.5% of the Company's net income per share for the 12 months ended on the last day of the previous quarter. The Second Amendment provides that proceeds from capital stock or indebtedness issued or incurred by the Company must be applied (subject to a $200 million basket for CERC and another $250 million basket for borrowings by the Company and other limited exceptions) to repay bank loans and reduce the bank facility. Similarly, cash proceeds from the sale of assets of more than $30 million or, if less, a group of sales aggregating more than $100 million, must be applied to repay bank loans and reduce the bank facility, except that proceeds of up to $120 million can be reinvested in the Company's businesses. On November 12, 2002, CenterPoint Houston entered into a $1.3 billion collateralized term loan maturing November 2005. The interest rate on the loan is LIBOR plus 9.75%, subject to a minimum rate of 12.75%. The loan is secured by CenterPoint Houston's general mortgage bonds. Proceeds from the loan were used to (1) repay CenterPoint Houston's $850 million term loan, (2) pay costs of issuance, (3) repay $300 million of debt that matured on November 15, 2002 and (4) to purchase $100 million of pollution control bonds on December 1, 2002. The loan agreement contains various business and financial covenants including a covenant restricting CenterPoint Houston's debt, excluding transition bonds, as a percent of its total capitalization to 68%. The loan agreement also limits incremental secured debt that may be issued by CenterPoint Houston to $300 million. Maturities. The Company's maturities of long-term debt and sinking fund requirements, excluding the ZENS obligation, are $706 million in 2003 (of which $500 million may be remarketed by an option holder to a maturity of 2013), $47 million in 2004, $5.6 billion in 2005, $210 million in 2006 and $68 million in 2007. The 2003 and 2004 amounts are net of sinking fund payments that can be satisfied with bonds that had been acquired and retired as of December 31, 2002. Liens. CenterPoint Houston's assets are subject to liens securing approximately $1.2 billion of first mortgage bonds. Sinking or improvement fund and replacement fund requirements on the first mortgage bonds may be satisfied by certification of property additions. Sinking fund and replacement fund requirements 19

for 2000, 2001 and 2002 have been satisfied by certification of property additions. The replacement fund requirement to be satisfied in 2003 is approximately $347 million, and the sinking fund requirement to be satisfied in 2003 is approximately $15 million. The Company expects CenterPoint Houston to meet these 2003 obligations by certification of property additions. CenterPoint Houston's assets are subject to liens securing approximately $1.8 billion of general mortgage bonds which are junior to the liens of the first mortgage bonds. Securitization. For a discussion of the securitization financing completed in October 2001, see Note 4(a). Purchase of Pollution Control Bonds. In the fourth quarter of 2002, the Company purchased $175 million of pollution control bonds issued on its behalf. The Company expects to remarket the bonds during the first half of 2003. Purchase of Convertible Debentures. At December 31, 2001 and 2002, CERC Corp. had issued and outstanding $86 million and $79 million, respectively, aggregate principal amount ($82 million and $76 million, respectively, carrying amount) of its 6% Convertible Subordinated Debentures due 2012 (Subordinated Debentures). The holders of the Subordinated Debentures receive interest quarterly and, prior to the Restructuring, had the right at any time on or before the maturity date thereof to convert each $50 principal amount of Subordinated Debentures into 0.65 shares of Reliant Energy common stock and $14.24 in cash. After the Restructuring, but prior to the Reliant Resources Distribution, each $50 principal amount of Subordinated Debentures was convertible into 0.65 shares of CenterPoint Energy common stock and $14.24 in cash. The Reliant Resources Distribution and the Texas Genco stock distribution changed the conversion rights for each $50 principal amount of Subordinated Debentures as follows:

SHARES OF CENTERPOINT ENERGY DATE EVENT CASH COMMON STOCK - ----------------------------------- ---------------------- ------ ------------------ October 1, 2002.................... Distribution of $14.24 1.02 Reliant Resources common stock December 21, 2002.................. Distribution of Texas $14.24 1.11 Genco common stock
During 2002, CERC Corp. purchased $6.6 million aggregate principal amount of its Subordinated Debentures. TERM Notes. CERC Corp.'s $500 million aggregate principal amount of 6 3/8% Term Enhanced ReMarketable Securities (TERM Notes) provide an investment bank with a call option, that gives it the right to have the TERM Notes tendered to it by the holders on November 1, 2003 and then remarketed if it chooses to exercise the option. The TERM Notes are unsecured obligations of CERC Corp. that bear interest at an annual rate of 6 3/8% through November 1, 2003. On November 1, 2003, the holders of the TERM Notes are required to tender their notes at 100% of their principal amount. The portion of the proceeds attributable to the call option premium will be amortized over the stated term of the securities. If the option is not exercised by the investment bank, CERC Corp. will repurchase the TERM Notes at 100% of their principal amount on November 1, 2003. If the option is exercised, the TERM Notes will be remarketed on a date, selected by CERC Corp., within the 52-week period beginning November 1, 2003. CERC Corp. may elect into this 52-week remarketing window only if its senior unsecured debt securities are rated at least Baa3 by Moody's Investors Service, Inc. and BBB- by Standard & Poor's Ratings Services, a division of The McGraw Hill Companies (unless the investment banker waives that requirement). During this period and prior to remarketing, the TERM Notes will bear interest at rates, adjusted weekly, based on an index selected by CERC Corp. CERC Corp. may elect to redeem the TERM Notes in whole, but not in part, from the investment bank prior to remarketing. If the TERM Notes are remarketed, the final maturity date of the TERM Notes will be November 1, 2013, subject to adjustment, and the effective interest rate on the 20

remarketed TERM Notes will be 5.66% plus CERC Corp.'s applicable credit spread at the time of such remarketing. Transportation Agreement. A subsidiary of CERC Corp. had an agreement (ANR Agreement) with ANR Pipeline Company (ANR) that contemplated that this subsidiary would transfer to ANR an interest in some of CERC Corp.'s pipeline and related assets. In 2001, this subsidiary was transferred to Reliant Resources as a result of CenterPoint Energy's planned divestiture of certain unregulated business operations. However, CERC retained the pipelines covered by the ANR Agreement. Therefore, the subsequent divestiture of Reliant Resources by CenterPoint Energy on September 30, 2002, resulted in a conversion of CERC's obligation to ANR into an obligation to Reliant Resources. As of December 31, 2001, the Company had recorded $41 million in long-term debt and as of December 31, 2002, the Company had recorded $5 million and $36 million in current portion of long-term debt and long-term debt, respectively, in its Consolidated Balance Sheets to reflect this obligation for the use of 130 million cubic feet (Mmcf)/day of capacity in some of CERC's transportation facilities. The volume of transportation will decline to 100 Mmcf/day in the year 2003 with a refund by CERC of $5 million to Reliant Resources. The ANR Agreement will terminate in 2005 with a refund of $36 million to Reliant Resources. (10) TRUST PREFERRED SECURITIES In February 1997, two Delaware statutory business trusts created by CenterPoint Energy (HL&P Capital Trust I and HL&P Capital Trust II) issued to the public (a) $250 million aggregate amount of preferred securities and (b) $100 million aggregate amount of capital securities, respectively. In February 1999, a Delaware statutory business trust created by CenterPoint Energy (REI Trust I) issued $375 million aggregate amount of preferred securities to the public. CenterPoint Energy accounts for REI Trust I, HL&P Capital Trust I and HL&P Capital Trust II as wholly owned consolidated subsidiaries. Each of the trusts used the proceeds of the offerings to purchase junior subordinated debentures issued by CenterPoint Energy having interest rates and maturity dates that correspond to the distribution rates and the mandatory redemption dates for each series of preferred securities or capital securities. The junior subordinated debentures are the trusts' sole assets and their entire operations. CenterPoint Energy considers its obligations under the Amended and Restated Declaration of Trust, Indenture, Guaranty Agreement and, where applicable, Agreement as to Expenses and Liabilities, relating to each series of preferred securities or capital securities, taken together, to constitute a full and unconditional guarantee by CenterPoint Energy of each trust's obligations with respect to the respective series of preferred securities or capital securities. The preferred securities and capital securities are mandatorily redeemable upon the repayment of the related series of junior subordinated debentures at their stated maturity or earlier redemption. Subject to some limitations, CenterPoint Energy has the option of deferring payments of interest on the junior subordinated debentures. During any deferral or event of default, CenterPoint Energy may not pay dividends on its capital stock. As of December 31, 2002, no interest payments on the junior subordinated debentures had been deferred. 21

The outstanding aggregate liquidation amount, distribution rate and mandatory redemption date of each series of the preferred securities or capital securities of the trusts described above and the identity and similar terms of each related series of junior subordinated debentures are as follows:

In June 1996, a Delaware statutory business trust created by CERC Corp. (CERC Trust) issued $173 million aggregate amount of convertible preferred securities to the public. CERC Corp. accounts for CERC Trust as a wholly owned consolidated subsidiary. CERC Trust used the proceeds of the offering to purchase convertible junior subordinated debentures issued by CERC Corp. having an interest rate and maturity date that correspond to the distribution rate and mandatory redemption date of the convertible preferred securities. The convertible junior subordinated debentures represent CERC Trust's sole asset and its entire operations. CERC Corp. considers its obligation under the Amended and Restated Declaration of Trust, Indenture and Guaranty Agreement relating to the convertible preferred securities, taken together, to constitute a full and unconditional guarantee by CERC Corp. of CERC Trust's obligations with respect to the convertible preferred securities. The convertible preferred securities are mandatorily redeemable upon the repayment of the convertible junior subordinated debentures at their stated maturity or earlier redemption. Effective January 7, 2003, the convertible preferred securities are convertible at the option of the holder into $33.62 of cash and 2.34 shares of CenterPoint Energy common stock for each $50 of liquidation value. As of December 31, 2001 and 2002, $0.4 million liquidation amount of convertible preferred securities were outstanding. The securities, and their underlying convertible junior subordinated debentures, bear interest at 6.25% and mature in June 2026. Subject to some limitations, CERC Corp. has the option of deferring payments of interest on the convertible junior subordinated debentures. During any deferral or event of default, CERC Corp. may not pay dividends on its common stock to CenterPoint Energy. As of December 31, 2002, no interest payments on the convertible junior subordinated debentures had been deferred. (11) STOCK-BASED INCENTIVE COMPENSATION PLANS AND EMPLOYEE BENEFIT PLANS (a) INCENTIVE COMPENSATION PLANS The Company has long-term incentive compensation plans (LICP) that provide for the issuance of stock-based incentives, including performance-based shares, performance-based units, restricted shares, stock options and stock appreciation rights to key employees of the Company, including officers. As of December 31, 2002, 344 current and 443 former employees of the Company participate in the plans. A maximum of approximately 37 million shares of CenterPoint Energy common stock may be issued under these plans. Performance-based shares, performance-based units and restricted shares are granted to employees without cost to the participants. The performance shares and units vest three years after the grant date based 22

upon the performance of the Company over a three-year cycle, except as discussed below. The restricted shares vest at various times ranging from immediately to at the end of a three-year period. Upon vesting, the shares are issued to the plan participants. During 2000, 2001 and 2002, the Company recorded compensation expense of $22 million, $6 million and $2 million, respectively, related to performance-based shares, performance-based units and restricted share grants. Included in these amounts is $7 million and $5 million in compensation expense for 2000 and 2001, respectively, related to Reliant Resources' participants. In addition, compensation benefit of $1 million was recorded in 2002 related to Reliant Resources' participants. Amounts for Reliant Resources' participants are reflected in discontinued operations in the Statements of Consolidated Operations. The following table summarizes the Company's performance-based units, performance-based shares and restricted share grant activity for the years 2000 through 2002:

The maximum value associated with the performance-based units granted in 2001 was $150 per unit. Effective with the Reliant Resources Distribution which occurred on September 30, 2002, the Company's compensation committee authorized the conversion of outstanding CenterPoint Energy performance-based shares for the performance cycle ending December 31, 2002 to a number of time-based restricted shares of CenterPoint Energy's common stock equal to the number of performance-based shares that would have vested if the performance objectives for the performance cycle were achieved at the maximum level for substantially all shares. These time-based restricted shares vested if the participant holding the shares remained employed with the Company or with Reliant Resources and its subsidiaries through December 31, 2002. On the date of the Reliant Resources Distribution, holders of these time-based restricted shares received shares of Reliant Resources common stock in the same manner as other holders of CenterPoint Energy common stock, but these shares of common stock were subject to the same time-based vesting schedule, as well as to the terms and conditions of the plan under which the original performance shares were granted. Thus, following the 23

Reliant Resources Distribution, employees who held performance-based shares under the LICP for the performance cycle ending December 31, 2002 held time-based restricted shares of CenterPoint Energy common stock and time-based restricted shares of Reliant Resources common stock, which vested following continuous employment through December 31, 2002. Effective with the Reliant Resources Distribution, the Company converted all outstanding CenterPoint Energy stock options granted prior to the Reliant Resources Offering to a combination of adjusted CenterPoint Energy stock options and Reliant Resources stock options. For the converted stock options, the sum of the intrinsic value of the CenterPoint Energy stock options immediately prior to the record date of the Reliant Resources Distribution equaled the sum of the intrinsic values of the adjusted CenterPoint Energy stock options and the Reliant Resources stock options granted immediately after the record date of the Reliant Resources Distribution. As such, Reliant Resources employees who do not work for the Company hold stock options of the Company. Both the number and the exercise price of all outstanding CenterPoint Energy stock options that were granted on or after the Reliant Resources Offering were adjusted to maintain the total intrinsic value of the grants. During January 2003, due to the distribution of Texas Genco stock, the Company granted additional CenterPoint Energy shares to participants with performance-based and time-based shares that had not yet vested as of the record date of December 20, 2002. These additional shares are subject to the same vesting schedule and the terms and conditions of the plan under which the original shares were granted. Also in connection with this distribution, both the number and the exercise price of all outstanding CenterPoint Energy stock options were adjusted to maintain the total intrinsic value of the stock option grants. Under the Company's plans, stock options generally become exercisable in one-third increments on each of the first through third anniversaries of the grant date. The exercise price is the average of the high and low sales price of the common stock on the New York Stock Exchange on the grant date. The Company applies APB Opinion No. 25, "Accounting for Stock Issued to Employees" (APB Opinion No. 25), and related interpretations in accounting for its stock option plans. Accordingly, no compensation expense has been recognized for these fixed stock options. The following table summarizes stock option activity related to the Company for the years 2000 through 2002:

In accordance with SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123), and SFAS No. 148, the Company applies the guidance contained in APB Opinion No. 25 and discloses the required pro forma effect on net income of the fair value based method of accounting for stock compensation. The weighted average fair values at date of grant for CenterPoint Energy options granted during 2000, 2001 and 2002 were $5.07, $9.25 and $1.40, respectively. The fair values were estimated using the Black-Scholes option valuation model with the following weighted-average assumptions:
2000 2001 2002 ------ ------ ------ Expected life in years..................................... 5 5 5 Interest rate.............................................. 6.57% 4.87% 2.83% Volatility................................................. 24.00% 31.91% 48.95% Expected common stock dividend............................. $ 1.50 $ 1.50 $ 0.64
Pro forma information for 2000, 2001 and 2002 is provided to take into account the amortization of stock-based compensation to expense on a straight-line basis over the vesting period. Had compensation costs been 25

determined as prescribed by SFAS No. 123, the Company's net income and earnings per share would have been as follows:

2000 2001 2002 ----- ----- ------- (IN MILLIONS, EXCEPT PER SHARE AMOUNTS) Net Income (loss): As reported............................................... $ 447 $ 980 $(3,920) Pro forma................................................. $ 437 $ 968 $(3,929) Basic Earnings Per Share: As reported............................................... $1.57 $3.38 $(13.16) Pro forma................................................. $1.54 $3.34 $(13.16) Diluted Earnings Per Share: As reported............................................... $1.56 $3.35 $(13.08) Pro forma................................................. $1.52 $3.31 $(13.08)
(B) PENSION AND POSTRETIREMENT BENEFITS The Company maintains a pension plan which is a non-contributory defined benefit plan covering substantially all employees using a cash balance formula. Under the cash balance formula, participants accumulate a retirement benefit based upon 4% of eligible earnings and accrued interest. Prior to 1999, the pension plan accrued benefits based on years of service, final average pay and covered compensation. As a result, certain employees participating in the plan as of December 31, 1998 are eligible to receive the greater of the accrued benefit calculated under the prior plan through 2008 or the cash balance formula. The Company's funding policy is to review amounts annually in accordance with applicable regulations in order to achieve adequate funding of projected benefit obligations. The assets of the pension plans consist principally of common stocks and interest bearing obligations. Included in such assets are approximately 4.5 million shares of CenterPoint Energy common stock contributed from treasury stock during 2001. As of December 31, 2002, the fair value of CenterPoint Energy common stock was $38 million or 4.7% of the pension plan assets. The Company provides certain healthcare and life insurance benefits for retired employees on a contributory and non-contributory basis. Employees become eligible for these benefits if they have met certain age and service requirements at retirement, as defined in the plans. Under plan amendments effective in early 1999, health care benefits for future retirees were changed to limit employer contributions for medical coverage. Such benefit costs are accrued over the active service period of employees. The net unrecognized transition obligation, resulting from the implementation of accrual accounting, is being amortized over approximately 20 years. The Company is required to fund a portion of its obligations in accordance with rate orders. All other obligations are funded on a pay-as-you-go basis. 26

The Company's net periodic cost (benefit) includes the following components relating to pension and postretirement benefits:

For the year ended December 31, 2001, the assumed health care cost trend rates were 7.5% for participants under age 65 and 8.5% for participants age 65 and over. For the year ended December 31, 2002, the assumed health cost trend rate was increased to 12% for all participants. The health care cost trend rates decline by .75% annually to 5.5% by 2011. If the health care cost trend rate assumption were increased by 1%, the accumulated postretirement benefit obligation as of December 31, 2002 would increase by 2.9%. The annual effect of a 1% increase on the sum of service and interest cost would be an increase of approximately 2.4%. If the health care cost trend rate assumption were decreased by 1%, the accumulated postretirement benefit obligation as of December 31, 2002 would decrease approximately 2.8%. The annual effect of a 1% decrease on the sum of service and interest cost would be a decrease of 2.4%. In addition to the non-contributory pension plans discussed above, the Company maintains a non-qualified pension plan which allow participants to retain the benefits to which they would have been entitled under the Company's non-contributory pension plan except for the federally mandated limits on these benefits or on the level of compensation on which these benefits may be calculated. The expense associated with this non-qualified plan was $25 million, $25 million and $9 million in 2000, 2001 and 2002, respectively. Included in the net benefit cost in 2001 and 2002 is $17 million and $3 million, respectively, of expense related to Reliant Resources' participants, which is reflected in discontinued operations in the Statements of Consolidated Operations. The accrued benefit liability for the non-qualified pension plan was $99 million and $83 million at December 31, 2001 and 2002, respectively. In addition, these accrued benefit liabilities include the recognition of minimum liability adjustments of $20 million as of December 31, 2001 and $23 million as of December 31, 2002, which are reported as a component of other comprehensive income, net of income tax effects. Included in these amounts is $30 million of accrued benefit liabilities for Reliant Resources' participants as of December 31, 2001. Of these liabilities, $11 million represents the recognition of minimum 28

liability adjustments, which are reported as discontinued operations on the Statements of Consolidated Comprehensive Income, net of income tax effects. (C) SAVINGS PLAN The Company has an employee savings plan that includes a cash or deferred arrangement under Section 401(k) of the Internal Revenue Code of 1986, as amended (the Code). Under the plan, participating employees may contribute a portion of their compensation, on a pre-tax or after-tax basis, generally up to a maximum of 16% of compensation. The Company matches 75% of the first 6% of each employee's compensation contributed. The Company may contribute an additional discretionary match of up to 50% of the first 6% of each employee's compensation contributed. These matching contributions are fully vested at all times. A substantial portion of the Company's match is initially invested in CenterPoint Energy common stock. Participating employees may elect to invest all or a portion of their contributions to the plan in CenterPoint Energy common stock, to have dividends reinvested in additional shares or to receive dividend payments in cash on any investment in CenterPoint Energy common stock, and to transfer all or part of their investment in CenterPoint Energy common stock to other investment options offered by the plan. The Company's savings plan includes an Employee Stock Ownership Plan (ESOP), which contains company stock, a portion of which is encumbered by a loan. Upon the release from the encumbrance of the loan, the Company may use released shares to satisfy its obligation to make matching contributions under the Company's savings plan. Generally, debt service on the loan is paid using all dividends on shares currently or formerly encumbered by the loan, interest earnings on funds held in trust and cash contributions by the Company. Shares of CenterPoint Energy common stock are released from the encumbrance of the loan based on the proportion of debt service paid during the period. The Company recognizes benefit expense equal to the fair value of the shares committed to be released. The Company credits to unearned shares the original purchase price of shares committed to be released to plan participants with the difference between the fair value of the shares and the original purchase price recorded to common stock. Dividends on allocated shares are recorded as a reduction to retained earnings. Dividends on unallocated shares are recorded as a reduction of principal or accrued interest on the loan. Share balances currently or formerly encumbered by a loan at December 31, 2001 and 2002 were as follows:

DECEMBER 31, -------------------------- 2001 2002 ------------ ----------- Allocated shares transferred/distributed from the savings plan...................................................... 2,740,328 5,943,297 Allocated shares............................................ 8,951,967 8,734,810 Unearned shares(1).......................................... 7,069,889 4,915,577 ------------ ----------- Total ESOP shares(1)...................................... 18,762,184 19,593,684 ============ =========== Fair value of unearned ESOP shares.......................... $187,493,456 $41,782,405 ============ ===========
- --------------- (1) During 2002, unearned shares and total shares were increased by 831,500 shares. This is due to additional shares purchased with proceeds from the sale of Reliant Resources common stock, which was received in connection with the Reliant Resources Distribution. As a result of the ESOP, the savings plan has significant holdings of CenterPoint Energy common stock. As of December 31, 2002, an aggregate of 32,099,870 shares of CenterPoint Energy's common stock were held by the savings plan, which represented 30% of its investments. Given the concentration of the investments in 29

CenterPoint Energy's common stock, the savings plan and its participants have market risk related to this investment. The Company's savings plan benefit expense was $52 million, $51 million and $47 million in 2000, 2001 and 2002, respectively. Included in these amounts are $5 million $16 million and $6 million of savings plan benefit expense for 2000, 2001 and 2002, respectively, related to Reliant Resources' participants, which is reflected as discontinued operations in the Statements of Consolidated Operations. (D) POSTEMPLOYMENT BENEFITS Net postemployment benefit costs for former or inactive employees, their beneficiaries and covered dependents, after employment but before retirement (primarily health care and life insurance benefits for participants in the long-term disability plan) were $2 million, $6 million and $12 million in 2000, 2001 and 2002, respectively. The Company's postemployment obligation is presented as a liability in the Consolidated Balance Sheets under the caption "Benefit Obligations." (E) OTHER NON-QUALIFIED PLANS The Company has in effect deferred compensation plans which permit eligible participants to elect each year to defer a percentage of that year's salary and up to 100% of that year's annual bonus. In general, employees who attain the age of 60 during employment and participate in the Company's deferred compensation plans may elect to have their deferred compensation amounts repaid in (a) fifteen equal annual installments commencing at the later of age 65 or termination of employment or (b) a lump-sum distribution following termination of employment. Interest generally accrues on deferrals at a rate equal to the average Moody's Long-Term Corporate Bond Index plus 2%, determined annually until termination when the rate is fixed at the rate in effect for the plan year immediately prior to that in which a participant attains age 65. During 2000, 2001 and 2002, the Company recorded interest expense related to its deferred compensation obligation of $14 million, $17 million and $11 million, respectively. Included in these amounts are $1 million, $4 million and $0.2 million of interest expense for 2000, 2001 and 2002, respectively, related to Reliant Resources' participants, which is reflected as discontinued operations in the Statements of Consolidated Operations. The discounted deferred compensation obligation recorded by the Company was $161 million and $132 million as of December 31, 2001 and 2002, respectively. The Company's obligations under other non-qualified plans are presented as a liability in the Consolidated Balance Sheets under the caption "Benefit Obligations." (F) OTHER EMPLOYEE MATTERS As of December 31, 2002, approximately 38% of the Company's employees are subject to collective bargaining agreements. Three of these agreements, covering approximately 24% of the Company's employees, will expire in 2003. 30

(13) COMMITMENTS AND CONTINGENCIES (a) COMMITMENTS AND GUARANTEES Environmental Capital Commitments. CenterPoint Energy anticipates investing up to $131 million in capital and other special project expenditures between 2003 and 2007 for environmental compliance. CenterPoint Energy anticipates expenditures to be as follows (in millions):

2003........................................................ $ 98 2004........................................................ 33 2005........................................................ -- 2006(1)..................................................... -- 2007(1)..................................................... -- ---- Total $131 ====
- --------------- (1) NOx control estimates for 2006 and 2007 have not been finalized. Fuel and Purchased Power. Fuel commitments include several long-term coal, lignite and natural gas contracts related to Texas power generation operations, which have various quantity requirements and durations that are not classified as non-trading derivatives assets and liabilities in the Company's Consolidated Balance Sheets as of December 31, 2002 as these contracts meet the SFAS No. 133 exception to be classified as "normal purchases contracts" or do not meet the definition of a derivative. Minimum payment obligations for coal and transportation agreements that extend through 2012 are approximately $292 million in 2003, $165 million in 2004, $169 million in 2005, $174 million in 2006 and $167 million in 2007. Purchase commitments related to lignite mining and lease agreements and purchased power are not material to CenterPoint Energy's operations. Prior to January 1, 2002, CenterPoint Houston was allowed recovery of these costs through rates for electric service. As of December 31, 2002, some of these contracts are above market. CenterPoint Energy anticipates that stranded costs associated with these obligations will be recoverable through the stranded cost recovery mechanisms contained in the Texas electric restructuring law. For information regarding the Texas electric restructuring law, see Note 4(a). CenterPoint Energy's other long-term fuel supply commitments, which have various quantity requirements and durations, are not considered material either individually or in the aggregate to its results of operations or cash flows. (b) LEASE COMMITMENTS The following table sets forth information concerning the Company's obligations under non-cancelable long-term operating leases at December 31, 2002, which primarily consist of rental agreements for building space, data processing equipment and vehicles, including major work equipment (in millions). 2003........................................................ $ 31 2004........................................................ 28 2005........................................................ 26 2006........................................................ 24 2007........................................................ 23 2008 and beyond............................................. 131 ---- Total..................................................... $263 ====

Total lease expense for all operating leases was $46 million, $45 million and $43 million during 2000, 2001 and 2002, respectively. (C) LEGAL, ENVIRONMENTAL AND OTHER REGULATORY MATTERS Legal Matters The Company's predecessor, Reliant Energy, and certain of its former subsidiaries are named as defendants in several lawsuits described below. Under a master separation agreement between Reliant Energy and Reliant Resources, the Company and its subsidiaries are entitled to be indemnified by Reliant Resources for any losses arising out of the lawsuits described under "California Class Actions and Attorney General Cases," "Long-Term Contract Class Action," "Washington and Oregon Class Actions," "Bustamante Price Reporting Class Action" and "Trading and Marketing Activities," including attorneys' fees and other costs. Pursuant to the indemnification obligation, Reliant Resources is defending the Company and its subsidiaries to the extent named in these lawsuits. The ultimate outcome of these matters cannot be predicted at this time. California Class Actions and Attorney General Cases. Reliant Energy, Reliant Resources, Reliant Energy Services, Inc.(Reliant Energy Services), Reliant Energy Power Generation, Inc. (REPG) and several other subsidiaries of Reliant Resources, as well as two former officers and one present officer of some of these companies, have been named as defendants in class action lawsuits and other lawsuits filed against a number of companies that own generation plants in California and other sellers of electricity in California markets. While the plaintiffs allege various violations by the defendants of antitrust laws and state laws against unfair and unlawful business practices, each of the lawsuits is grounded on the central allegation that the defendants conspired to drive up the wholesale price of electricity. In addition to injunctive relief, the plaintiffs in these lawsuits seek treble the amount of damages alleged, restitution of alleged overpayments, disgorgement of alleged unlawful profits for sales of electricity, costs of suit and attorneys' fees. All of these suits originally were filed in state courts in San Diego, San Francisco and Los Angeles Counties. The suits in San Diego and Los Angeles Counties were consolidated and removed to the federal district court in San Diego, but on December 13, 2002, that court remanded the suits to the state courts. Prior to the remand, Reliant Energy was voluntarily dismissed from two of the suits. Several parties, including the Reliant defendants, have appealed the judge's remand decision. The United States court of appeals has entered a briefing schedule that could result in oral arguments by summer of 2003. Proceedings before the state court are expected to resume during the first quarter of 2003. In March and April 2002, the California Attorney General filed three complaints, two in state court in San Francisco and one in the federal district court in San Francisco, against Reliant Energy, Reliant Resources, Reliant Energy Services and other subsidiaries of Reliant Resources alleging, among other matters, violations by the defendants of state laws against unfair and unlawful business practices arising out of transactions in the markets for ancillary services run by the California independent systems operator, charging unjust and unreasonable prices for electricity, in violation of antitrust laws in connection with the acquisition in 1998 of electric generating facilities located in California. The complaints variously seek restitution and disgorgement of alleged unlawful profits for sales of electricity, civil penalties and fines, injunctive relief against unfair competition, and undefined equitable relief. Reliant Resources has removed the two state court cases to the federal district court in San Francisco where all three cases are now pending. Following the filing of the Attorney General cases, seven additional class action cases were filed in state courts in Northern California. Each of these purports to represent the same class of California ratepayers, assert the same claims as asserted in the other California class action cases, and in some instances repeat as well the allegations in the Attorney General cases. All of these cases have been removed to federal district court in San Diego. Reliant Resources has not filed an answer in any of these cases. The plaintiffs have agreed to a stipulated order that would require the filing of a consolidated complaint by early March 2003 and the filing of the defendants' initial response to the complaint within 60 days after the consolidated complaint is 32

filed. In all of these cases filed before the federal and state courts in California, the Reliant defendants have filed or intend to file motions to dismiss on grounds that the claims are barred by federal preemption and the filed rate doctrine. Long-Term Contract Class Action. In October 2002, a class action was filed in state court in Los Angeles against Reliant Energy and several subsidiaries of Reliant Resources. The complaint in this case repeats the allegations asserted in the California class actions as well as the Attorney General cases and also alleges misconduct related to long-term contracts purportedly entered into by the California Department of Water Resources. None of the Reliant entities, however, has a long-term contract with the Department of Water Resources. This case has been removed to federal district court in San Diego. Washington and Oregon Class Actions. In December 2002, a lawsuit was filed in Circuit Court of the State of Oregon for the County of Multnomah on behalf of a class of all Oregon purchasers of electricity and natural gas. Reliant Energy, Reliant Resources and several Reliant Resources subsidiaries are named as defendants, along with many other electricity generators and marketers. Like the other lawsuits filed in California, the plaintiffs claim the defendants manipulated wholesale power prices in violation of state and federal law. The plaintiffs seek injunctive relief and payment of damages based on alleged overcharges for electricity. Also in December 2002, a nearly identical lawsuit on behalf of consumers in the State of Washington was filed in federal district court in Seattle. Reliant Resources has removed the Oregon suit to federal district court in Portland. It is anticipated that before answering the lawsuits, the defendants will file motions to dismiss on the grounds that the claims are barred by federal preemption and by the filed rate doctrine. Bustamante Price Reporting Class Action. In November 2002, California Lieutenant Governor Cruz Bustamante filed a lawsuit in state court in Los Angeles on behalf of a class of purchasers of gas and power alleging violations of state antitrust laws and state laws against unfair and unlawful business practices based on an alleged conspiracy to report and publish false and fraudulent natural gas prices with an intent to affect the market prices of natural gas and electricity in California. Reliant Energy, Reliant Resources and several Reliant Resources subsidiaries are named as defendants, along with other market participants and publishers of some of the price indices. The complaint seeks injunctive relief, compensatory and punitive damages, restitution of alleged overpayment, disgorgement of all profits and funds acquired by the alleged unlawful conduct, costs of suit and attorneys' fees. The parties have stipulated to a schedule that would require the defendants to respond to the complaint by March 31, 2003. The Reliant defendants intend to deny both their alleged violation of any laws and their alleged participation in any conspiracy. Trading and Marketing Activities. Reliant Energy has been named as a party in several lawsuits and regulatory proceedings relating to the trading and marketing activities of its former subsidiary, Reliant Resources. In June 2002, the SEC advised Reliant Resources and Reliant Energy that it had issued a formal order in connection with its investigation of Reliant Resources' financial reporting, internal controls and related matters. The Company understands that the investigation is focused on Reliant Resources' same-day commodity trading transactions involving purchases and sales with the same counterparty for the same volume at substantially the same price and certain structured transactions. These matters were previously the subject of an informal inquiry by the SEC. Reliant Resources and the Company are cooperating with the SEC staff. In connection with the Texas Utility Commission's industry-wide investigation into potential manipulation of the ERCOT market on and after July 31, 2001, Reliant Energy and Reliant Resources have provided information to the Texas Utility Commission concerning their scheduling and trading activities. Fifteen class action lawsuits filed in May, June and July 2002 on behalf of purchasers of securities of Reliant Resources and/or Reliant Energy have been consolidated in federal district court in Houston. Reliant Resources and certain of its executive officers are named as defendants. Reliant Energy is also named as a 33

defendant in seven of the lawsuits. Two of the lawsuits also name as defendants the underwriters of the Reliant Resources Offering. One lawsuit names Reliant Resources' and Reliant Energy's independent auditors as a defendant. The consolidated amended complaint seeks monetary relief purportedly on behalf of three classes: (1) purchasers of Reliant Energy common stock from February 3, 2000 to May 13, 2002; (2) purchasers of Reliant Resources common stock on the open market from May 1, 2001 to May 13, 2002; and (3) purchasers of Reliant Resources common stock in the Reliant Resources Offering or purchasers of shares that are traceable to the Reliant Resources Offering. The plaintiffs allege, among other things, that the defendants misrepresented their revenues and trading volumes by engaging in round-trip trades and improperly accounted for certain structured transactions as cash-flow hedges, which resulted in earnings from these transactions being accounted for as future earnings rather than being accounted for as earnings in fiscal year 2001. In February 2003, a lawsuit was filed by three individuals in federal district court in Chicago against CenterPoint Energy and certain former and current officers of Reliant Resources for alleged violations of federal securities laws. The plaintiffs in this lawsuit allege that the defendants violated federal securities laws by issuing false and misleading statements to the public, and that the defendants made false and misleading statements as part of an alleged scheme to inflate artificially trading volumes and revenues. In addition, the plaintiffs assert claims of fraudulent and negligent misrepresentation and violations of Illinois consumer law. The defendants expect to file a motion to transfer this lawsuit to the federal district court in Houston and to consolidate this lawsuit with the consolidated lawsuits described above. The Company believes that none of these lawsuits has merit because, among other reasons, the alleged misstatements and omissions were not material and did not result in any damages to any of the plaintiffs. In May 2002, three class action lawsuits were filed in federal district court in Houston on behalf of participants in various employee benefits plans sponsored by Reliant Energy. Reliant Energy and its directors are named as defendants in all of the lawsuits. Two of the lawsuits have been dismissed without prejudice. The remaining lawsuit alleges that the defendants breached their fiduciary duties to various employee benefits plans, directly or indirectly sponsored by Reliant Energy, in violation of the Employee Retirement Income Security Act. The plaintiffs allege that the defendants permitted the plans to purchase or hold securities issued by Reliant Energy when it was imprudent to do so, including after the prices for such securities became artificially inflated because of alleged securities fraud engaged in by the defendants. The complaints seek monetary damages for losses suffered by a putative class of plan participants whose accounts held Reliant Energy or Reliant Resources securities, as well as equitable relief in the form of restitution. In October 2002, a derivative action was filed in the federal district court in Houston, against the directors and officers of the Company. The complaint sets forth claims for breach of fiduciary duty, waste of corporate assets, abuse of control and gross mismanagement. Specifically, the shareholder plaintiff alleges that the defendants caused the Company to overstate its revenues through so-called "round trip" transactions. The plaintiff also alleges breach of fiduciary duty in connection with the spin-off and the Reliant Resources Offering. The complaint seeks monetary damages on behalf of the Company as well as equitable relief in the form of a constructive trust on the compensation paid to the defendants. The defendants have filed a motion to dismiss this case on the ground that the plaintiff did not make an adequate demand on the Company before filing suit. A Special Litigation Committee appointed by the Company's board of directors is investigating similar allegations made in a June 28, 2002 demand letter sent on behalf of a Company shareholder. The letter states that the shareholder and other shareholders are considering filing a derivative suit on behalf of the Company and demands that the Company take several actions in response to alleged round-trip trades occurring in 1999, 2000, and 2001. The Special Litigation Committee is reviewing the demands made by the shareholder to determine if these proposed actions are in the best interests of the Company. 34

Reliant Energy Municipal Franchise Fee Lawsuits. In February 1996, the cities of Wharton, Galveston and Pasadena filed suit, for themselves and a proposed class of all similarly situated cities in Reliant Energy's electric service area, against Reliant Energy and Houston Industries Finance, Inc. (formerly a wholly owned subsidiary of Reliant Energy) alleging underpayment of municipal franchise fees. The plaintiffs claim that they are entitled to 4% of all receipts of any kind for business conducted within these cities over the previous four decades. A jury trial of the original claimant cities (but not the class of cities) in the 269th Judicial District Court for Harris County, Texas, ended in April 2000 (the Three Cities case). Although the jury found for Reliant Energy on many issues, it found in favor of the original claimant cities on three issues, and assessed a total of $4 million in actual and $30 million in punitive damages. However, the jury also found in favor of Reliant Energy on the affirmative defense of laches, a defense similar to a statute of limitations defense, due to the original claimant cities having unreasonably delayed bringing their claims during the 43 years since the alleged wrongs began. The trial court in the Three Cities case granted most of Reliant Energy's motions to disregard the jury's findings. The trial court's rulings reduced the judgment to $1.7 million, including interest, plus an award of $13.7 million in legal fees. In addition, the trial court granted Reliant Energy's motion to decertify the class. Following this ruling, 45 cities filed individual suits against Reliant Energy in the District Court of Harris County. On February 27, 2003, the state court of appeals in Houston rendered an opinion reversing the judgment against the Company and rendering judgment that the Three Cities take nothing by their claims. The court of appeals found that the jury's finding of laches barred all of the Three Cities' claims and that the Three Cities were not entitled to recovery of any attorneys' fees. The judgment of the court of appeals is subject to motions for rehearing and an appeal to the Texas Supreme Court. The extent to which issues in the Three Cities case may affect the claims of the other cities served by Reliant Energy cannot be assessed until judgments are final and no longer subject to appeal. However, the court of appeals' ruling appears to be consistent with Texas Supreme Court opinions. The Company estimates the range of possible outcomes for recovery by the plaintiffs in the Three Cities case to be between $-0- and $18 million inclusive of interest and attorneys' fees. Natural Gas Measurement Lawsuits. In 1997, a suit was filed under the Federal False Claims Act against RERC Corp. (now CERC Corp.) and certain of its subsidiaries alleging mismeasurement of natural gas produced from federal and Indian lands. The suit seeks undisclosed damages, along with statutory penalties, interest, costs, and fees. The complaint is part of a larger series of complaints filed against 77 natural gas pipelines and their subsidiaries and affiliates. An earlier single action making substantially similar allegations against the pipelines was dismissed by the federal district court for the District of Columbia on grounds of improper joinder and lack of jurisdiction. As a result, the various individual complaints were filed in numerous courts throughout the country. This case has been consolidated, together with the other similar False Claims Act cases, in the federal district court in Cheyenne, Wyoming. In addition, CERC Corp., CenterPoint Energy Gas Transmission Company, CenterPoint Energy Field Services, Inc., and CenterPoint Energy-Mississippi River Transmission Corporation are defendants in a class action filed in May 1999 against approximately 245 pipeline companies and their affiliates. The plaintiffs in the case purport to represent a class of natural gas producers and fee royalty owners who allege that they have been subject to systematic gas mismeasurement by the defendants for more than 25 years. The plaintiffs seek compensatory damages, along with statutory penalties, treble damages, interest, costs and fees. The action is currently pending in state court in Stevens County, Kansas. Motions to dismiss and class certification issues have been briefed and argued. City of Tyler, Texas, Gas Costs Review. By letter to CenterPoint Energy Entex (Entex) dated July 31, 2002, the City of Tyler, Texas, forwarded various computations of what it believes to be excessive costs ranging from $2.8 million to $39.2 million for gas purchased by Entex for resale to residential and small commercial customers in that city under supply agreements in effect since 1992. Entex's gas costs for its Tyler 35

system are recovered from customers pursuant to tariffs approved by the city and filed with both the city and the Railroad Commission of Texas (the Railroad Commission). Pursuant to an agreement, on January 29, 2003, Entex and the city filed a Joint Petition for Review of Charges for Gas Sales (Joint Petition) with the Railroad Commission. The Joint Petition requests that the Railroad Commission determine whether Entex has properly and lawfully charged and collected for gas service to its residential and commercial customers in its Tyler distribution system for the period beginning November 1, 1992, and ending October 31, 2002. The Company believes that all costs for Entex's Tyler distribution system have been properly included and recovered from customers pursuant to Entex's filed tariffs and that the city has no legal or factual support for the statements made in its letter. Gas Cost Recovery Suits. In October 2002, a suit was filed in state district court in Wharton County, Texas against the Company, CERC, Entex Gas Marketing Company, and others alleging fraud, violations of the Texas Deceptive Trade Practices Act, violations of the Texas Utility Code, civil conspiracy and violations of the Texas Free Enterprise and Antitrust Act. The plaintiffs seek class certification, but no class has been certified. The plaintiffs allege that defendants inflated the prices charged to residential and small commercial consumers of natural gas. In February 2003, a similar suit was filed against CERC in state court in Caddo Parish, Louisiana purportedly on behalf of a class of residential or business customers in Louisiana who allegedly have been overcharged for gas or gas service provided by CERC. The plaintiffs in both cases seek restitution for the alleged overcharges, exemplary damages and penalties. The Company denies that CERC has overcharged any of its customers for natural gas and believes that the amounts recovered for purchased gas have been in accordance with what is permitted by state regulatory authorities. Other Proceedings. The Company is involved in other proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. The Company's management currently believes that the disposition of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows. Environmental Matters Clean Air Standards. Based on current limitations of the Texas Commission on Environmental Quality regarding NOx emissions in the Houston area, the Company anticipates it will have invested at least $682 million for emission control equipment through 2005, including $551 million expended from January 1, 1999 through December 31, 2002, with possible additional expenditures after 2005. NOx control estimates for 2006 and 2007 have not been finalized. The Texas electric restructuring law provides for stranded cost recovery for expenditures incurred before May 1, 2003 to achieve the NOx reduction requirements. Incurred costs include costs for which contractual obligations have been made. The Texas Utility Commission has determined that the Company's emission control plan is the most effective control option and that up to $699 million is eligible for cost recovery, the exact amount to be determined in the 2004 true-up proceeding. In addition, the Company is required to provide $16.2 million in funding for certain NOx reduction projects associated with East Texas pipeline companies. These funds are also eligible for cost recovery. Hydrocarbon Contamination. On August 24, 2001, 37 plaintiffs filed suit against REGT, Reliant Energy Pipeline Services, Inc., RERC Corp., Reliant Energy Services, other Reliant Energy entities and third parties in the 1st Judicial District Court, Caddo Parish, Louisiana. The petition has now been supplemented seven times. As of November 21, 2002, there were 695 plaintiffs, a majority of whom are Louisiana residents. In addition to the Reliant Energy entities, the plaintiffs have sued the State of Louisiana through its Department of Environmental Quality, several individuals, some of whom are present employees of the State of Louisiana, the Bayou South Gas Gathering Company, L.L.C., Martin Timber Company, Inc., and several trusts. Additionally on April 4, 2002, two plaintiffs filed a separate suit with identical allegations against the same parties in the same court. More recently, on January 6, 2003, two other plaintiffs filed a third suit of 36

similar allegations against the Company, as well as other defendants, in Bossier Parish (26th Judicial District Court). The suits allege that, at some unspecified date prior to 1985, the defendants allowed or caused hydrocarbon or chemical contamination of the Wilcox Aquifer, which lies beneath property owned or leased by certain of the defendants and which is the sole or primary drinking water aquifer in the area. The primary source of the contamination is alleged by the plaintiffs to be a gas processing facility in Haughton, Bossier Parish, Louisiana known as the "Sligo Facility." This facility was purportedly used for gathering natural gas from surrounding wells, separating gasoline and hydrocarbons from the natural gas for marketing, and transmission of natural gas for distribution. This site was originally leased and operated by predecessors of REGT in the late 1940s and was operated until Arkansas Louisiana Gas Company ceased operations of the plant in the late 1970s. Beginning about 1985, the predecessors of certain Reliant Energy defendants engaged in a voluntary remediation of any subsurface contamination of the groundwater below the property they own or lease. This work has been done in conjunction with and under the direction of the Louisiana Department of Environmental Quality. The plaintiffs seek monetary damages for alleged damage to the aquifer underlying their property, unspecified alleged personal injuries, alleged fear of cancer, alleged property damage or diminution of value of their property, and, in addition, seek damages for trespass, punitive, and exemplary damages. The quantity of monetary damages sought is unspecified. As of December 31, 2002, the Company is unable to estimate the monetary damages, if any, that the plaintiffs may be awarded in these matters. Manufactured Gas Plant Sites. CERC and its predecessors operated manufactured gas plants (MGP) in the past. In Minnesota, remediation has been completed on two sites, other than ongoing monitoring and water treatment. There are five remaining sites in CERC's Minnesota service territory, two of which CERC believes were neither owned or operated by CERC, and for which CERC believes it has no liability. At December 31, 2001 and 2002, CERC had accrued $23 million and $19 million, respectively, for remediation of the Minnesota sites. At December 31, 2002, the estimated range of possible remediation costs was $8 million to $44 million based on remediation continuing for 30 to 50 years. The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRP), if any, and the remediation methods used. CERC has an environmental expense tracker mechanism in its rates in Minnesota. CERC has collected $12 million at December 31, 2002 to be used for future environmental remediation. CERC has received notices from the United States Environmental Protection Agency and others regarding its status as a PRP for other sites. Based on current information, the Company has not been able to quantify a range of environmental expenditures for potential remediation expenditures with respect to other MGP sites. Mercury Contamination. The Company's pipeline and distribution operations have in the past employed elemental mercury in measuring and regulating equipment. It is possible that small amounts of mercury may have been spilled in the course of normal maintenance and replacement operations and that these spills may have contaminated the immediate area with elemental mercury. This type of contamination has been found by the Company at some sites in the past, and the Company has conducted remediation at these sites. It is possible that other contaminated sites may exist and that remediation costs may be incurred for these sites. Although the total amount of these costs cannot be known at this time, based on experience by the Company and that of others in the natural gas industry to date and on the current regulations regarding remediation of these sites, the Company believes that the costs of any remediation of these sites will not be material to the Company's financial condition, results of operations or cash flows. 37

Other Environmental. From time to time the Company has received notices from regulatory authorities or others regarding its status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, the Company has been named as a defendant in litigation related to such sites and in recent years has been named, along with numerous others, as a defendant in several lawsuits filed by a large number of individuals who claim injury due to exposure to asbestos while working at sites along the Texas Gulf Coast. Most of these claimants have been workers who participated in construction of various industrial facilities, including power plants, and some of the claimants have worked at locations owned by the Company. The Company anticipates that additional claims like those received may be asserted in the future and intends to continue vigorously contesting claims which it does not consider to have merit. Although their ultimate outcome cannot be predicted at this time, the Company does not believe, based on its experience to date, that these matters, either individually or in the aggregate, will have a material adverse effect on the Company's financial condition, results of operations or cash flows. Department of Transportation In December 2002, Congress enacted the Pipeline Safety Improvement Act of 2002. This legislation applies to the Company's interstate pipelines as well as its intra-state pipelines and local distribution companies. The legislation imposes several requirements related to ensuring pipeline safety and integrity. It requires companies to assess the integrity of their pipeline transmission and distribution facilities in areas of high population concentration and further requires companies to perform remediation activities, in accordance with the requirements of the legislation, over a 10-year period. In January 2003, the U.S. Department of Transportation published a notice of proposed rulemaking to implement provisions of the legislation. The Department of Transportation is expected to issue final rules by the end of 2003. While the Company anticipates that increased capital and operating expenses will be required to comply with the requirements of the legislation, it will not be able to quantify the level of spending required until the Department of Transportation's final rules are issued. Other Matters The Company is involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. Some of these proceedings involve substantial amounts. The Company's management regularly analyzes current information and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters. The Company's management believes that the disposition of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows. (d) OPERATIONS AGREEMENT WITH CITY OF SAN ANTONIO Texas Genco has a joint operating agreement with the City Public Service Board of San Antonio (CPS) to share savings from the joint dispatching of each party's generating assets. Dispatching the two generating systems jointly results in savings of fuel and related expenses because there is a more efficient utilization of each party's lowest cost resources. The two parties equally share the savings resulting from joint dispatch. The agreement terminates in 2009. (e) NUCLEAR INSURANCE Texas Genco and the other owners of the South Texas Project maintain nuclear property and nuclear liability insurance coverage as required by law and periodically review available limits and coverage for additional protection. The owners of the South Texas Project currently maintain $2.75 billion in property 38

damage insurance coverage, which is above the legally required minimum, but is less than the total amount of insurance currently available for such losses. Pursuant to the Price Anderson Act, the maximum liability to the public of owners of nuclear power plants was $9.3 billion as of December 31, 2002. Owners are required under the Price Anderson Act to insure their liability for nuclear incidents and protective evacuations. Texas Genco and the other owners of the South Texas Project currently maintain the required nuclear liability insurance and participate in the industry retrospective rating plan. There can be no assurance that all potential losses or liabilities will be insurable, or that the amount of insurance will be sufficient to cover them. Any substantial losses not covered by insurance would have a material effect on the Company's financial condition, results of operations and cash flows. (f) NUCLEAR DECOMMISSIONING Texas Genco contributed $14.8 million per year in 2000 and 2001 to trusts established to fund its share of the decommissioning costs for the South Texas Project. In 2002, Texas Genco contributed $2.9 million to these trusts. There are various investment restrictions imposed upon Texas Genco by the Texas Utility Commission and the NRC relating to Texas Genco's nuclear decommissioning trusts. Additionally, Texas Genco's board of directors and CenterPoint Energy's board of directors have each appointed two members to the Nuclear Decommissioning Trust Investment Committee which establishes the investment policy of the trusts and oversees the investment of the trusts' assets. The securities held by the trusts for decommissioning costs had an estimated fair value of $163 million as of December 31, 2002, of which approximately 49% were fixed-rate debt securities and the remaining 51% were equity securities. For a discussion of the accounting treatment for the securities held in the nuclear decommissioning trust, see Note 3(k). In July 1999, an outside consultant estimated Texas Genco's portion of decommissioning costs to be approximately $363 million. While the funding levels currently exceed minimum NRC requirements, no assurance can be given that the amounts held in trust will be adequate to cover the actual decommissioning costs of the South Texas Project. Such costs may vary because of changes in the assumed date of decommissioning and changes in regulatory requirements, technology and costs of labor, materials and equipment. Pursuant to the Texas electric restructuring law, costs associated with nuclear decommissioning that have not been recovered as of January 1, 2002, will continue to be subject to cost-of-service rate regulation and will be included in a charge to transmission and distribution customers. CenterPoint Energy is contractually obligated to indemnify Texas Genco from and against any obligations relating to the decommissioning not otherwise satisfied through collections by CenterPoint Houston. For information regarding the effect of the business separation plan on funding of the nuclear decommissioning trust fund, see Note 4(b). 39
