RELIANT ENERGY RESOURCES CORP. Overview We are a wholly owned subsidiary of Reliant Energy. We conduct our operations primarily in the natural gas industry. Our operations include gathering, transmission, marketing, storage and distribution services. Our operations are currently organized into two business segments, natural gas distribution and pipelines and gathering. Natural Gas Distribution. We conduct our natural gas distribution operations through three unincorporated divisions, Reliant Energy Arkla, Reliant Energy Entex and Reliant Energy Minnegasco. Our 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. These operations are regulated as gas utility operations in the jurisdictions served by these divisions. . Reliant Energy Arkla. Reliant Energy Arkla provides natural gas distribution services in Arkansas, Louisiana, Oklahoma and Texas. The largest metropolitan areas served by Arkla are Little Rock, Arkansas and Shreveport, Louisiana. In 2000, approximately 67.7% of Arkla's total throughput was attributable to retail sales of gas and approximately 32.3% was attributable to transportation services. . Reliant Energy Entex. Reliant Energy Entex provides natural gas distribution services in over 500 communities in Louisiana, Mississippi and Texas. The largest metropolitan area served by Entex is Houston, Texas. In 2000, approximately 96.9% of Entex's total throughput was attributable to retail sales of gas and approximately 3.1% was attributable to transportation services. . Reliant Energy Minnegasco. Reliant Energy Minnegasco provides natural gas distribution services in over 240 communities in Minnesota. The largest metropolitan area served by Minnegasco is Minneapolis, Minnesota. In 2000, approximately 96% of Minnegasco's total throughput was attributable to retail sales of gas and approximately 4% was attributable to transportation services. Our natural gas distribution business segment also includes certain non-rate regulated retail natural gas services activities. Pipelines and Gathering. We provide interstate gas transportation and related services through two wholly owned subsidiaries, Reliant Energy Gas Transmission Company, or "REGT," and Mississippi River Transmission Corporation, or "MRT." As of December 31, 2000, we owned and operated over 8,200 miles of transmission lines and six natural gas storage facilities located across the south-central United States. We store, transport and deliver natural gas on behalf of various shippers, primarily to utilities, industrial customers and third party pipeline interconnects. In 2000, approximately 36% of our pipelines and gathering business segment's total operating revenue was attributable to services provided by REGT to Reliant Energy Arkla and approximately 14% of its total operating revenue was attributable to services provided by MRT to Laclede Gas Company, or "Laclede," an unaffiliated distribution company that provides natural gas utility service to the greater St. Louis metropolitan area in Illinois and Missouri. Our pipelines and gathering business segment provides service to Reliant Energy Arkla and Laclede under several long-term firm storage and transportation agreements. The expiration dates for the service agreements with Laclede range from October 2001 through May 2002. We are currently negotiating the terms and conditions of a proposed renewal of these agreements with Laclede. At the end of 2000, REGT renewed various contracts for firm transportation and storage services with Reliant Energy Arkla. These renewals extended the term of service in Arkla's major market areas to 2005. We also provide project management and facility operation services to affiliates and third parties through our wholly owned subsidiary Reliant Energy Pipeline Services, Inc. In addition, our pipelines and gathering business segment provides natural gas gathering and related services, including liquids extraction and other well operating services. We conduct our natural gas gathering operations through a wholly owned subsidiary, Reliant Energy Field Services, Inc., or "RFS." As of December 31, 2000, RFS operated approximately 4,000 miles of gathering pipelines which collect natural gas from more than 200 separate systems located in major producing fields in Arkansas, Louisiana, Oklahoma and Texas.

Recent Developments Transfer of our Wholesale Energy Trading, Marketing and Risk Management Operations to Reliant Resources, Inc. On December 31, 2000, we transferred our trading, marketing and risk management business and operations and a company that holds an investment in marketable equity securities to Reliant Resources, Inc., or "RRI," a wholly owned subsidiary of Reliant Energy, in a series of stock transfers and a merger. As consideration for the stock transfers and the merger, RRI paid us $120 million, subject to a working capital adjustment which reduced the total amount of the payment made by RRI by $25.6 million. The stock transfers and the merger discussed above were implemented as a part of Reliant Energy's previously announced restructuring plan. Under this restructuring plan, Reliant Energy plans to divide into two publicly traded companies in order to separate its unregulated businesses from its regulated businesses. Under this plan, Reliant Energy would restructure its regulated operations into a holding company structure in which a new corporate entity would be formed as the parent with Reliant Energy's regulated businesses, including us, as subsidiaries. The holding company for the regulated businesses is expected to own Reliant Energy's electric transmission and distribution operations, its natural gas distribution businesses, its U.S. interstate pipelines and gas gathering operations, certain other interests and, initially, its currently regulated electric generating assets in Texas. For more information regarding Reliant Energy's restructuring plan, please refer to our Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 2000 and September 30, 2000 and to our Current Report on Form 8-K dated July 27, 2000. For more information regarding the stock transfers and the merger described above, including unaudited pro forma condensed consolidated financial statements showing the effects of the stock transfers and the merger, please refer to our Current Report on Form 8-K dated December 31, 2000. Please read "Where You Can Find More Information" in the accompanying prospectus. Reported Earnings for the Year 2000. On January 26, 2001, Reliant Energy reported its adjusted earnings for the year ended December 31, 2000. Reliant Energy reported that operating income for its natural gas distribution segment for the year ended December 31, 2000 declined to $113 million, compared to $158 million for 1999. The decline was primarily due to increased operating expenses, including costs incurred in connection with certain non-rate regulated retail natural gas business activities outside our established market areas which have been discontinued, additional provisions against receivable balances resulting from the implementation of a new billing system for Reliant Energy Arkla, increased benefit expenses relating to an updated actuarial valuation of employee benefit plans and additional severance/relocation costs resulting from the implementation of our strategic plan to merge operational management of Reliant Energy Arkla and Reliant Energy Entex. Our operations compose substantially all of the operations included in Reliant Energy's natural gas distribution segment. Reliant Energy reported that operating income for its pipelines and gathering segment for the year ended December 31, 2000 was $137 million compared to $131 million for 1999. The increase was primarily due to increased gas gathering and processing revenues. Our operations compose all of the operations of Reliant Energy's pipelines and gathering segment. S-6

USE OF PROCEEDS We estimate that the net proceeds (before expenses) from the sale of the notes will be approximately $544.6 million. We intend to use the net proceeds: . to pay a $400 million dividend to Reliant Energy, and . for other general corporate purposes, which may include, but are not limited to, working capital, capital expenditures and intercompany investments.

DESCRIPTION OF THE NOTES We will issue the notes under an indenture, dated as of February 1, 1998, between us and The Chase Manhattan Bank (formerly Chase Bank of Texas, National Association), as trustee, which is more fully described in the accompanying prospectus. The terms of the notes will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939. The following description is a summary of the material provisions of the notes and the indenture. This summary is not complete and is qualified in its entirety by reference to the indenture. You should carefully read the summary below, the description of the general terms and provisions of our debt securities set forth in the accompanying prospectus and the provisions of the indenture that may be important to you before investing in the notes. We may issue debt securities from time to time in one or more series under the indenture. There is no limitation on the amount of debt securities we may issue under the indenture. Our 6 1/2% Debentures due February 1, 2008 ($300 million outstanding as of December 31, 2000), our 6 3/8% Term Enhanced ReMarketable Securities ($500 million outstanding as of December 31, 2000) and our 8.125% Notes due 2005 ($325 million outstanding as of December 31, 2000) are currently outstanding under the indenture. The notes will be a new series of debt securities under the indenture. Ranking of the Notes The notes will: . be general unsecured obligations, . rank equally with all of our other unsecured and unsubordinated indebtedness, and . with respect to the assets and earnings of our subsidiaries, effectively rank below all of the liabilities of our subsidiaries. Subject to the exceptions, and subject to compliance with the applicable requirements, set forth in the indenture, we may discharge our obligations under the indenture with respect to the notes as described under "Description of Our Debt Securities--Defeasance and Covenant Defeasance" in the accompanying prospectus. Principal, Maturity and Interest The notes will mature on February 15, 2011. The notes are initially limited to $550,000,000 aggregate principal amount. However, we may issue additional notes of this series from time to time, without the consent of the holders of the notes. The notes will initially be issued only in registered, book-entry form, in denominations of $1,000 and multiples thereof as described under "Description of Our Debt Securities--Global Securities" in the accompanying prospectus. We will issue global securities in an aggregate denomination equal to the principal amount of the notes. Interest on the notes will: . accrue at the rate of 7.75% per year from February 21, 2001, . be payable semi-annually in arrears on each February 15 and August 15, beginning August 15, 2001, . be payable to the person in whose name the notes are registered at the close of business on the relevant February 1 and August 1 preceding the applicable interest payment date, which we refer to with respect to the notes as "regular record dates," S-10

. be computed on the basis of a 360-day year comprised of twelve 30-day months, and . be payable on overdue interest to the extent permitted by law at the same rate as interest is payable on principal. If any interest payment date, maturity date or redemption date falls on a day that is not a business day, the payment will be made on the next business day with the same force and effect as if made on the relevant interest payment date, maturity date or redemption date. Unless we default on a payment, no interest will accrue for the period from and after the applicable maturity date or redemption date. Optional Redemption We may redeem the notes, in whole or in part, at our option exercisable at any time from time to time upon not less than 30 and not more than 60 days' notice as provided in the indenture, on any date prior to their maturity at a redemption price equal to: . 100% of the principal amount of the notes redeemed, plus . accrued and unpaid interest thereon, if any, to, but excluding, the redemption date, plus . the make-whole premium described below, if any. The redemption price will never be less than 100% of the principal amount of the notes plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. The amount of the make-whole premium with respect to any note to be redeemed will be equal to the excess, if any, of: (1) the sum of the present values, calculated as of the redemption date, of: . each interest payment that, but for such redemption, would have been payable on the note or portion thereof being redeemed on each interest payment date occurring after the redemption date (excluding any accrued and unpaid interest for the period prior to the redemption date), and . the principal amount that, but for such redemption, would have been payable at the final maturity of the note or portion thereof being redeemed, over (2) the principal amount of the note being redeemed. The present values of interest and principal payments referred to in a clause (1) above will be determined in accordance with generally accepted principles of financial analysis. These present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the redemption date at a discount rate equal to the comparable treasury yield (as defined below) plus 30 basis points. The make-whole premium will be calculated by an independent investment banking institution of national standing appointed by us. If we fail to appoint an independent investment banking institution at least 45 days prior to the redemption date, or if the independent investment banking institution we appoint is unwilling or unable to calculate the make-whole premium, the calculation will be made by Banc of America Securities LLC. If Banc of America Securities LLC is unwilling or unable to make the calculation, we will appoint a different independent investment banking institution of national standing to make the calculation. For purposes of determining the make-whole premium, "comparable treasury yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Securities that have a constant maturity that corresponds to the remaining term to maturity of the notes, calculated to the nearest 1/12th of a year. The comparable treasury yield will be determined as of the third business day immediately preceding the applicable redemption date. S-11

The weekly average yields of United States Treasury Securities will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or any successor release. If this statistical release sets forth a weekly average yield for United States Treasury Securities having a constant maturity that is the same as the remaining term calculated as set forth above, then the comparable treasury yield will be equal to such weekly average yield. In all other cases, the comparable treasury yield will be calculated by interpolation on a straight-line basis, between the weekly average yields on the United States Treasury Securities that have a constant maturity closest to and greater than the remaining term and the United States Treasury Securities that have a constant maturity closest to and less than the remaining term (in each case as set forth in the H.15 statistical release or any successor release). Any weekly average yields calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward. If weekly average yields for United States Treasury Securities are not available in the H.15 statistical release or otherwise, then the comparable treasury yield will be calculated by interpolation of comparable rates selected by an independent investment banking institution selected in the manner described in the second preceding paragraph. If we redeem the notes in part, the trustee will select the notes for redemption on a pro rata basis, by lot or by such other method as the trustee in its sole discretion deems fair and appropriate. We will only redeem notes in multiples of $1,000 in original principal amount. If any note is to be redeemed in part only, the notice of redemption will state the portion of the principal amount to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued upon the cancellation of the original note. Sinking Fund We are not obligated to make mandatory redemption or sinking fund payments with respect to the notes. Restrictive Covenants The indenture does not limit the amount of indebtedness or other obligations that we may incur and does not contain provisions that would give holders of the notes the right to require us to repurchase their notes in the event of a change in control of us, or in the event we enter into one or more highly leveraged transactions, regardless of whether a rating decline results therefrom, or in the event we dispose of one or more of our business units, nor are any such events deemed to be events of default under the terms of the indenture. The indenture contains certain covenants for the benefit of the holders of the notes which we have summarized below and refer to as the "restrictive covenants." The restrictive covenants are applicable to the notes; provided, however, that the restrictive covenants will terminate pursuant to the termination provision of the indenture and will no longer be applicable to the notes on and after the date, which we refer to as the "termination date," on which there remains outstanding, in the aggregate, no more than $200 million in principal amount of our: . Medium-Term Notes, Series B due through 2001 ($144.1 million outstanding as of December 31, 2000), . 8.90% Debentures due 2006 ($145.1 million outstanding as of December 31, 2000), and . long-term indebtedness (but excluding for this purpose any long-term indebtedness incurred pursuant to any revolving credit facility, letter of credit facility or other similar bank credit facility) issued subsequent to the issuance of the notes and prior to the termination date containing covenants substantially similar to the restrictive covenants but not containing the termination provision. We collectively refer to the debt described above as the "Resources Corp. Long- Term Indebtedness." Each issue of Resources Corp. Long-Term Indebtedness has covenants similar to the restrictive covenants summarized below. Various agreements governing some of our short-term indebtedness, including our revolving S-12

credit facility, contain provisions limiting our ability to encumber our property or the property of our subsidiaries and to effect sale and leaseback transactions that differ from the restrictive covenants. As of December 31, 2000, approximately $289.2 million aggregate principal amount of Resources Corp. Long-Term Indebtedness was outstanding. We currently expect the termination date to occur in the second quarter of 2001. Limitations on Liens. We will not, and we will not permit any restricted subsidiary (as defined below) to, pledge, mortgage or hypothecate, or permit to exist, except in our favor or in favor of any restricted subsidiary, any mortgage, pledge, lien or other encumbrance, which we collectively refer to as a "lien" or "liens," upon, any principal property (as defined below) at any time owned by us or by a restricted subsidiary, to secure any indebtedness (as defined below), unless effective provision is made whereby outstanding notes will be secured equally and ratably therewith (or prior thereto), and with any other indebtedness similarly entitled to be equally and ratably secured. This restriction will not apply to or prevent the creation or existence of: . liens on any property held or used by us or a restricted subsidiary in connection with the exploration for, development of or production of, oil, gas, natural gas (including liquefied gas and storage gas), other hydrocarbons, helium, coal, metals, minerals, steam, timber, geothermal or other natural resources or synthetic fuels, such properties to include, but not be limited to, our or a restricted subsidiary's interest in any mineral fee interests, oil, gas or other mineral leases, royalty, overriding royalty or net profits interests, production payments and other similar interests, wellhead production equipment, tanks, field gathering lines, leasehold or field separation and processing facilities, compression facilities and other similar personal property and fixtures, . liens on oil, gas, natural gas (including liquified gas and storage gas), other hydrocarbons, helium, coal, metals, minerals, steam, timber, geothermal or other natural resources or synthetic fuels produced or recovered from any property, an interest in which is owned or leased by us or a restricted subsidiary, . liens (or certain extensions, renewals or refundings thereof) upon any property acquired, constructed or improved before or after the date of the indenture, created at the time of acquisition or within one year thereafter to secure all or a portion of the purchase price thereof or the cost of construction or improvement, or existing thereon at the date of acquisition, provided that every such mortgage, pledge, lien or encumbrance applies only to the property so acquired or constructed and fixed improvements thereon, . liens upon any property acquired by any corporation that is or becomes a restricted subsidiary after the date of the indenture, each of which we refer to as an "acquired entity," provided that every such mortgage, pledge, lien or encumbrance: . will either: . exist prior to the time the acquired entity becomes a restricted subsidiary, or . be created at the time the acquired entity becomes a restricted subsidiary or within one year thereafter to secure payment of the acquisition price thereof, and . will only apply to those properties owned by the acquired entity at the time it becomes a restricted subsidiary or thereafter acquired by it from sources other than us or any other restricted subsidiary, . pledges of current assets, in the ordinary course of business, to secure current liabilities, . deposits to secure public or statutory obligations, . liens upon any office, data processing or transportation equipment, . liens created or assumed in connection with the issuance of debt securities, the interest on which is excludable from gross income of the holder of such security pursuant to the Internal Revenue Code, for the purpose of financing the acquisition or construction of property to be used by us or a restricted subsidiary, S-13

. pledges or assignments of accounts receivable or conditional sales contracts or chattel mortgages and evidence of indebtedness secured thereby, received in connection with the sale of goods or merchandise to customers, . certain liens for taxes, judgments and attachments, or . other liens specified in the indenture. Notwithstanding the foregoing, we or a restricted subsidiary may issue, assume or guarantee indebtedness secured by a mortgage which would otherwise be subject to the foregoing restrictions in an aggregate amount which, together with all of our other indebtedness or indebtedness of a restricted subsidiary secured by a mortgage which (if originally issued, assumed or guaranteed at such time) would otherwise be subject to the foregoing restrictions (not including secured indebtedness permitted under the foregoing exceptions) and the value of all sale and leaseback transactions (as defined below) existing at such time (other than sale and leaseback transactions in which the property involved would have been permitted to be mortgaged under the third or fourth bullet points above), does not at the time such indebtedness is incurred exceed 5% of consolidated net tangible assets (as defined below), as shown on our most recent audited consolidated balance sheet preceding the date of determination. Limitation on Sale and Leaseback Transactions. We will not, and we will not permit any restricted subsidiary to, engage in a sale and leaseback transaction of any principal property unless the net proceeds of such sale are at least equal to the fair value of such principal property (as determined by our board of directors) and either: . we or such restricted subsidiary would be entitled under the indenture to incur indebtedness secured by a lien on the principal property to be leased without equally and ratably securing the notes pursuant to the exceptions provided in the third and fourth bullet points of the second sentence of "--Limitations on Liens" above, or . we apply an amount not less than the fair value of such property: . to the payment or other retirement of certain of our long-term indebtedness or long-term indebtedness of a restricted subsidiary, or . to the purchase at not more than the fair value of principal property (other than that involved in such sale and leaseback transaction).

All indebtedness secured by a lien upon property owned by us or any subsidiary and upon which indebtedness any such corporation customarily pays interest, although any such corporation has not assumed or become liable for the payment of such indebtedness, is also deemed to be indebtedness of any such corporation. All indebtedness for borrowed money incurred by other persons which is directly guaranteed as to payment of principal by us or any subsidiary will for all purposes of the indenture be deemed to be indebtedness of any such corporation, but no other contingent obligation of any such corporation in respect of indebtedness incurred by other persons shall for any purpose be deemed indebtedness of such corporation. Indebtedness of us or any subsidiary does not include: . amounts which are payable only out of all or a portion of the oil, gas, natural gas, helium, coal, metals, minerals, steam, timber, hydrocarbons, or geothermal or other natural resources produced, derived or extracted from properties owned or developed by such corporation, . any indebtedness incurred to finance oil, gas, natural gas, helium, coal, metals, minerals, steam, timber, hydrocarbons, or geothermal or other natural resources or synthetic fuel exploration or development, payable, with respect to principal and interest, solely out of the proceeds of oil, gas, natural gas, helium, coal, metals, minerals, steam, timber, hydrocarbons, or geothermal or other natural resources or synthetic fuel to be produced, sold and/or delivered by us or any subsidiary, . indirect guarantees or other contingent obligations in connection with the indebtedness of others, including agreements, contingent or otherwise, with such other persons or with third persons with respect to, or to permit or ensure the payment of, obligations of such other persons, including, without limitation, agreements to advance or supply funds to or to invest in such other persons, or agreements to pay for property, products or services of such other persons (whether or not conferred, delivered or rendered), and any demand charge, throughput, take-or-pay, keep-well, make-whole, cash deficiency, maintenance of working capital or earnings or similar agreements, and . any guarantees with respect to lease or other similar periodic payments to be made by other persons. "Principal property" means any natural gas distribution property, natural gas pipeline or gas processing plant located in the United States, except any such property that in the opinion of our board of directors is not of material importance to the total business conducted by us and our consolidated subsidiaries. "Principal property" shall not include any oil or gas property or the production or proceeds of production from an oil or gas producing property or the production or any proceeds of production of gas processing plants or oil or gas or petroleum products in any pipeline or storage field. "Restricted subsidiary" means any subsidiary which owns a principal property.

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to the approval of certain legal matters by counsel and to certain other conditions. Under the underwriting agreement, the underwriters are obligated to purchase all the notes if they purchase any of the notes. We have been advised by the underwriters that they propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement, and to certain dealers at such price less a concession not in excess of 0.40% of the principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.25% of the principal amount of the notes to certain other dealers. After the initial public offering, the public offering price and such concessions may be changed. In connection with this offering, certain underwriters and their affiliates may engage in transactions that stabilize, maintain or otherwise affect the market price of the notes. Such transactions may include stabilization transactions effected in accordance with Rule 104 of Regulation M under the Securities Exchange Act of 1934, pursuant to which such persons may bid for or purchase the notes for the purpose of stabilizing their market price. The underwriters also may create a short position for the account of the underwriters by selling more of the notes in connection with the offering than they are committed to purchase from us, and in such case may purchase the notes in the open market following completion of the offering to cover such short position. Any of the transactions described in this paragraph may result in the maintenance of the price of the notes at a level above that which might otherwise prevail in the open market. None of the transactions described in this paragraph is required, and, if they are undertaken, they may be discontinued at any time. The underwriters may also impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when they, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member. We have been advised by the underwriters that they intend to make a market in the notes but that they are not obligated to do so and may discontinue market-making at any time without notice. The notes are a new issue of securities with no established trading market. No assurance can be given as to the liquidity of, or the trading markets for, the notes. S-17

The underwriting agreement provides that we will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933 or contribute to payments the underwriters may be required to make in respect of any of these liabilities. The underwriters or their affiliates have performed certain investment banking and advisory and general financing and banking services for us from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time, be customers of, engage in transactions with or perform services for us in the ordinary course of their business. We estimate expenses for this offering to be approximately $440,000. S-18

Reliant Energy Resources Corp. Overview We are a wholly owned subsidiary of Reliant Energy. We conduct our operations primarily in the natural gas industry. Our operations include gathering, transmission, marketing, storage and distribution services. Our operations are currently organized into two operating units, natural gas distribution and pipelines and gathering. Natural Gas Distribution. We conduct our natural gas distribution operations through three unincorporated divisions, Reliant Energy Arkla, Reliant Energy Entex and Reliant Energy Minnegasco. Our 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. These operations are regulated as gas utility operations in the jurisdictions served by these divisions. Pipelines and Gathering. We provide interstate gas transportation and related services through two wholly owned subsidiaries, Reliant Energy Gas Transmission Company and Mississippi River Transmission Corporation. As of December 31, 2000, we owned and operated over 8,200 miles of transmission lines and six natural gas storage facilities located across the south-central United States. We store, transport and deliver natural gas on behalf of various shippers, primarily to utilities, industrial customers and third party pipeline interconnects. We also provide project management and facility operation services to affiliates and third parties through our wholly owned subsidiary Reliant Energy Pipeline Services, Inc. In addition, our pipelines and gathering business unit provides natural gas gathering and related services, including liquids extraction and other well operating services. We conduct our natural gas gathering operations through a wholly owned subsidiary, Reliant Energy Field Services, Inc., or "RFS." As of December 31, 2000, RFS operated approximately 4,000 miles of gathering pipelines which collect natural gas from more than 200 separate systems located in major producing fields in Arkansas, Louisiana, Oklahoma and Texas. Recent Developments Transfer of our Wholesale Energy Trading, Marketing and Risk Management Operations to Reliant Resources, Inc. On December 31, 2000, we transferred all of the outstanding capital stock of Reliant Energy Services International, Inc., or "RESI," Arkla Finance Corporation, or "Arkla Finance," and Reliant Energy Europe Trading & Marketing, Inc., or "RE Europe Trading," all of which were our wholly owned subsidiaries, to Reliant Resources, Inc., or "RRI." RRI is a wholly owned subsidiary of Reliant Energy. As a result of these stock transfers, RESI, Arkla Finance and RE Europe Trading each became a wholly owned subsidiary of RRI. Also, on December 31, 2000, a wholly owned subsidiary of RRI merged with and into our wholly owned subsidiary Reliant Energy Services, Inc., or "RES," with RES as the surviving corporation. As a result of this merger, the outstanding capital stock of RES was converted into the right to receive cash consideration, the outstanding capital stock of the RRI subsidiary was converted into RES capital stock and RES became a wholly owned subsidiary of RRI. As consideration for the merger, RRI paid us $120 million, subject to a working capital adjustment. RES, RESI and RE Europe Trading conducted our trading, marketing and risk management business and operations. Arkla Finance is a company that holds an investment in marketable equity securities. The stock transfers and the merger discussed above were implemented as a part of Reliant Energy's previously announced restructuring plan. Under this restructuring plan, Reliant Energy plans to divide into two publicly traded companies in order to separate its unregulated businesses from its regulated businesses. For more information regarding Reliant Energy's restructuring, please refer to our Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 2000 and September 30, 2000 and to our Current Report on Form 8- K dated July 27, 2000. For more information regarding the stock transfers and the merger described above, including unaudited pro forma condensed consolidated financial statements showing the effects of the stock transfers and the merger, please refer to our Current Report on Form 8-K dated December 31, 2000. Please read "Where You Can Find More Information." 5

Ratio of Earnings to Fixed Charges The following table sets forth our ratios of earnings from continuing operations to fixed charges for each of the periods indicated: Nine Months Ended September 30, Year Ended December 31, ----------------- -------------------------------- Pro Pro Forma Forma 2000(2) 2000 1999 1999(2) 1999 1998 1997 1996 1995 ------- ---- ---- ------- ---- ---- ---- ---- ---- Ratio of earnings from continuing operations to fixed charges (1)........ 1.80 1.52 2.41 2.31 2.44 2.71 1.87 2.09 1.69 - -------- (1) We do not believe that the ratios for the nine-month periods are necessarily indicative of the ratios for the twelve-month periods due to the seasonal nature of our business. The ratios were calculated pursuant to applicable rules of the SEC. (2) The pro forma ratios for the nine months ended September 30, 2000 and the twelve months ended December 31, 1999 reflect the effects of the merger and stock transfers described under "Reliant Energy Resources Corp.--Recent Developments--Transfer of our Wholesale Energy Trading, Marketing and Risk Management Operations to Reliant Resources, Inc." as if these transactions had occurred on January 1, 2000 and January 1, 1999, respectively. The pro forma ratios do not purport to present our actual ratios for these periods as if the transactions had occurred on those dates, nor are they necessarily indicative of our future ratios, financial position or results of operations.

These purposes may include, but are not limited to: . working capital, . capital expenditures, . acquisitions, . the payment of dividends to Reliant Energy, and . the repayment or refinancing of our indebtedness, including inter- company indebtedness. 6

The security registrar or designated transfer agent will exchange or transfer the debt securities if it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any exchange or registration of transfer of debt securities. However, we may require payment of a sum sufficient to cover any tax or other governmental charge payable for the registration of transfer or exchange. Unless we inform you otherwise in the prospectus supplement, we will appoint the trustee as security registrar. We will identify any transfer agent in addition to the security registrar in the prospectus supplement. (Section 305) At any time we may: . designate additional transfer agents, . rescind the designation of any transfer agent, or . approve a change in the office of any transfer agent. However, we are required to maintain a transfer agent in each place of payment for the debt securities at all times. (Sections 305 and 1002) 9

In the event we elect to redeem a series of debt securities, neither we nor the applicable trustee will be required to register the transfer or exchange of any debt security of that series: . during the period beginning at the opening of business 15 days before the day we mail the notice of redemption for the series and ending at the close of business on the day the notice is mailed, or . if we have selected the series for redemption, in whole or in part, except for the unredeemed portion of the series. (Section 305) Global Securities Unless we inform you otherwise in the prospectus supplement, some or all of the debt securities of any series may be represented, in whole or in part, by one or more global securities. The global securities will have a total principal amount equal to the debt securities they represent. Unless we inform you otherwise in the prospectus supplement, each global security representing debt securities will be deposited with, or on behalf of, The Depository Trust Company, referred to as "DTC," or any other successor depository we may appoint. We refer to DTC or the other depository in this prospectus as the "depositary." Each global security will be registered in the name of the depositary or its nominee. Each global security will bear a legend referring to the restrictions on exchange and registration of transfer of global securities that we describe below and any other matters required by the indenture. Unless we inform you otherwise in the prospectus supplement, we will not issue debt securities in definitive form. Global securities may not be exchanged, in whole or in part, for debt securities registered, and no transfer of a global security, in whole or in part, may be registered in the name of any person other than the depositary for the global security or any nominee of the depositary unless: . the depositary has notified us that it is unwilling or unable to continue as depositary for the global security or has ceased to be qualified to act as depositary as required by the indenture, . an event of default with respect to the global security has occurred and is continuing, . we determine in our sole discretion that the global security will be so exchangeable or transferable, or . any other circumstances in addition to or in lieu of those described above that we may describe in the prospectus supplement have occurred. All debt securities issued in exchange for a global security or any portion of a global security will be registered in the names directed by the depositary. (Sections 204 and 305) Regarding DTC DTC is: . a limited-purpose trust company organized under the New York Banking Law, . a "banking organization" within the meaning of the New York Banking Law, . a member of the Federal Reserve System, . a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and . a "clearing agency" registered under Section 17A of the Securities Exchange Act of 1934. DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic 10

computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include: . securities brokers and dealers, . banks, . trust companies, and . clearing corporations and some other organizations. DTC is owned by a number of direct participants and by The New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc. Access to DTC's book-entry system is also available to others, such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, referred to as indirect participants. The rules applicable to DTC and its participants are on file with the SEC. Upon our issuance of debt securities represented by a global security, purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC's records. The ownership interest of each actual purchaser of each debt security, referred to as a beneficial owner, is in turn to be recorded on the direct and indirect participants' records. Beneficial owners will not receive written confirmation from DTC of their purchase. However, beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued. The laws of some states require that some purchasers of securities take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security. So long as the depositary for the global security, or its nominee, is the registered owner of the global security, the depositary or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Except as described above, beneficial owners will not: . be entitled to have debt securities represented by the global security registered in their names, . receive or be entitled to receive physical delivery of debt securities in definitive form, and . be considered the owners or holders thereof under the indenture. To facilitate subsequent transfers, all debt securities deposited by participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The deposit of debt securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC's records reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Neither DTC nor Cede & Co. will consent or vote with respect to debt securities. Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date, identified in a listing attached to the omnibus proxy. 11

We will make payments of principal, premium, if any, and interest on the debt securities represented by the global security registered in the name of the depositary or its nominee through the trustee or a paying agent, which may also be the trustee, to the depositary or its nominee, as the case may be, as the registered owner of the global security. Neither we, the trustees, nor the paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. We have been advised that DTC will credit direct participants' accounts on the payable date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payment on the payable date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers registered in "street name," and will be the responsibility of such participant and not of DTC, the paying agent, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to DTC is either our responsibility or the responsibility of the paying agent. Disbursement of these payments to direct participants is the responsibility of DTC. Disbursement of these payments to the beneficial owners is the responsibility of direct and indirect participants. DTC may discontinue providing its services as securities depositary with respect to the debt securities at any time by giving us reasonable notice. Under such circumstances, in the event that we do not obtain a successor securities depositary, debt securities certificates will be printed and delivered to the holders of record. Additionally, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor depositary) with respect to the debt securities. In that event, certificates for the debt securities will be printed and delivered to the holders of record. We cannot assure you that DTC will distribute payments on the debt securities made to DTC or its nominee as the registered owner or any redemption or other notices to the participants, or that the participants or others will distribute the payments or notices to the beneficial owners, or that they will do so on a timely basis, or that DTC will serve and act in the manner described in this prospectus. Beneficial owners should make appropriate arrangements with their broker or dealer regarding distribution of information regarding the debt securities that may be transmitted by or through DTC. According to DTC, the foregoing information with respect to DTC has been provided to the industry for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind. We have obtained the information in this section concerning DTC and the DTC's book-entry system from sources that we believe are reliable. However, we take no responsibility for the accuracy of this information. Payment and Paying Agents Unless we inform you otherwise in the prospectus supplement, we will pay interest on the debt securities to the persons in whose names the debt securities are registered at the close of business on the regular record date for each interest payment. However, unless we inform you otherwise in the prospectus supplement, we will pay the interest payable on the debt securities at their stated maturity to the persons we pay the principal amount of the debt securities. The initial payment of interest on any series of debt securities issued between a regular record date and the related interest payment date will be payable in the manner provided by the terms of the series, which we will describe in the prospectus supplement. (Section 307) Unless we inform you otherwise in the prospectus supplement, we will pay principal, premium, if any, and interest on the debt securities at the offices of the paying agents we designate. However, except in the case of a global security, we may pay interest by: . check mailed to the address of the person entitled to the payment as it appears in the security register, or 12

. wire transfer in immediately available funds to the place and account designated in writing by the person entitled to the payment as specified in the security register. We will designate Reliant Energy as the sole paying agent for the debt securities unless we inform you otherwise in the prospectus supplement. If we initially designate any other paying agents for a series of debt securities, we will identify them in the prospectus supplement. At any time, we may designate additional paying agents or rescind the designation of any paying agents. However, we are required to maintain a paying agent in each place of payment for the debt securities at all times. (Sections 307 and 1002) Any money deposited with the trustee or any paying agent for the payment of principal, premium, if any, and interest on the debt securities that remains unclaimed for two years after the date the payments became due, may be repaid to us upon our request. After we have been repaid, holders entitled to those payments may only look to us for payment as our unsecured general creditors. The trustee and any paying agents will not be liable for those payments after we have been repaid. (Section 1003) Covenants We will describe any restrictive covenants for any series of debt securities in the prospectus supplement. Consolidation, Merger and Sale of Assets Unless we inform you otherwise in the prospectus supplement, we may not consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety, to any person, referred to as a "successor person," and we may not permit any person to consolidate with or merge into, or convey, transfer or lease its properties and assets substantially as an entirety to us, unless: . the successor person, if any, is a corporation, partnership, trust or other entity organized and validly existing under the laws of any domestic jurisdiction, . the successor person assumes our obligations with respect to the debt securities and the indenture, . immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, would occur and be continuing, and . we have delivered to the trustee the certificates and opinions required under the indenture. (Section 801) Events of Default Unless we inform you otherwise in the prospectus supplement, each of the following will be an event of default under the indenture for a series of debt securities: . our failure to pay principal or premium, if any, on that series when due, . our failure to pay any interest on that series for 30 days, . our failure to deposit any sinking fund payment, when due, relating to that series, . our failure to perform, or our breach in any material respect of, any other covenant or warranty in the indenture, other than a covenant or warranty included in the indenture solely for the benefit of another series of debt securities, for 90 days after either the trustee or holders of at least 25% in principal amount of the outstanding debt securities of that series have given us written notice of the breach in the manner required by the indenture, . specified events involving bankruptcy, insolvency or reorganization, and . any other event of default we may provide for that series, 13

provided, however, that no event described in the fourth, fifth and sixth bullet points above will be an event of default until an officer of the trustee, assigned to and working in the trustee's corporate trust department, has actual knowledge of the event or until the trustee receives written notice of the event at its corporate trust office, and the notice refers to the debt securities generally, us or the indenture. (Section 501) If the principal, premium, if any, or interest on any series of debt securities is payable in a currency other than $US and the currency is not available to us for making payments due to the imposition of exchange controls or other circumstances beyond our control, we may satisfy our obligations to holders of the debt securities by making payment in $US in an amount equal to the $US equivalent of the amount payable in the other currency. This amount will be determined by the trustee by reference to the noon buying rate in The City of New York for cable transfers for the other currency, referred to as the "exchange rate," as reported or otherwise made available by the Federal Reserve Bank of New York on the date of the payment, or, if the exchange rate is not then available, on the basis of the most recently available exchange rate. Any payment made in $US under these circumstances will not be an event of default under the indenture. (Section 501) If an event of default for a series of debt securities occurs and is continuing, either the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of the debt securities of that series due and immediately payable. In order to declare the principal amount of the series of debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the series of debt securities. This right does not apply if: . an event of default described in the fourth or fifth bullet points above occurs, or . an event of default described in the sixth bullet point above that applies to all outstanding debt securities occurs. If any of these events of default occurs and is continuing, either the trustee or holders of at least 25% in principal amount of all of the debt securities then outstanding, treated as one class, may declare the principal amount of all of the debt securities then outstanding to be due and payable immediately. In order to declare the principal amount of the debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the debt securities. After any declaration of acceleration of a series of debt securities, but before a judgment or decree for payment, the holders of a majority in principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul the declaration of acceleration if all events of default, other than the non-payment of principal, have been cured or waived as provided in the indenture. (Section 502) For information as to waiver of defaults, please refer to the "--Modification and Waiver" section below. If an event of default occurs and is continuing, the trustee will generally have no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders offer reasonable indemnity to the trustee. (Section 603) The holders of a majority in principal amount of the outstanding debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee for the debt securities of that series, provided that: . the direction is not in conflict with any law or the indenture, . the trustee may take any other action it deems proper which is not inconsistent with the direction, and . the trustee will generally have the right to decline to follow the direction if an officer of the trustee determines, in good faith, that the proceeding would involve the trustee in personal liability or would otherwise be contrary to applicable law. (Section 512) 14

A holder of a debt security of any series may only pursue a remedy under the indenture if: . the holder gives the trustee written notice of a continuing event of default for that series, . holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the trustee to pursue that remedy, . the holder offers reasonable indemnity to the trustee, . the trustee fails to pursue that remedy within 60 days after receipt of the request, and . during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request. (Section 507) However, these limitations do not apply to a suit by a holder of a debt security demanding payment of the principal, premium, if any, or interest on a debt security on or after the date the payment is due. (Section 508) We will be required to furnish to the trustee annually a statement by some of our officers regarding our performance or observance of any of the terms of the indenture and specifying all of our known defaults, if any. (Section 1004) Modification and Waiver We may enter into one or more supplemental indentures with the trustee without the consent of the holders of the debt securities in order to: . evidence the succession of another corporation to us, or successive successions and the assumption of our covenants, agreements and obligations by a successor, . add to our covenants for the benefit of the holders or to surrender any of our rights or powers, . add events of default for any series of debt securities, . add or change any provisions of the indenture to the extent necessary to issue debt securities in bearer form, . add to, change or eliminate any provision of the indenture applying to one or more series of debt securities, provided that if such action adversely affects the interests of any holders of debt securities of any series, the addition, change or elimination will become effective with respect to that series only when no security of that series remains outstanding, . convey, transfer, assign, mortgage or pledge any property to or with the trustee or to surrender any right or power conferred upon us by the indenture, . establish the form or terms of any series of debt securities, . provide for uncertificated securities in addition to certificated securities, . evidence and provide for successor trustees or to add or change any provisions to the extent necessary to appoint a separate trustee or trustees for a specific series of debt securities, . correct any ambiguity, defect or inconsistency under the indenture, provided that such action does not adversely affect the interests of the holders of debt securities of any series, . supplement any provisions of the indenture necessary to defease and discharge any series of debt securities, provided that such action does not adversely affect the interests of the holders of any series of debt securities, . comply with the rules or regulations of any securities exchange or automated quotation system on which any debt securities are listed or traded, or 15

. add, change or eliminate any provisions of the indenture in accordance with any amendments to the Trust Indenture Act of 1939, provided that the action does not adversely affect the rights or interests of any holder of debt securities. (Section 901) We may enter into one or more supplemental indentures with the trustee in order to add to, change or eliminate provisions of the indenture or to modify the rights of the holders of one or more series of debt securities if we obtain the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the supplemental indenture, treated as one class. However, without the consent of the holders of each outstanding debt security affected by the supplemental indenture, we may not enter into a supplemental indenture that: . changes the stated maturity of the principal of, or any installment of principal of or interest on, any debt security, except to the extent permitted by the indenture, . reduces the principal amount of, or any premium or interest on, any debt security, . reduces the amount of principal of an original issue discount security or any other debt security payable upon acceleration of the maturity thereof, . changes the place or currency of payment of principal, premium, if any, or interest, . impairs the right to institute suit for the enforcement of any payment on any debt security, . reduces the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of the indenture, . reduces the percentage in principal amount of outstanding debt securities of any series necessary for waiver of compliance with certain provisions of the indenture or for waiver of certain defaults, . makes certain modifications to such provisions with respect to modification and waiver, . makes any change that adversely affects the right to convert or exchange any debt security or decrease the conversion or exchange rate or increases the conversion price of any convertible or exchangeable debt security, or . changes the terms and conditions pursuant to which any series of debt securities that are secured in a manner adverse to the holders of the debt securities. (Section 902) Holders of a majority in principal amount of the outstanding debt securities of any series may waive past defaults or compliance with restrictive provisions of the indenture. However, the consent of holders of each outstanding debt security of a series is required to: . waive any default in the payment of principal, premium, if any, or interest, or . waive any covenants and provisions of the indenture that may not be amended without the consent of the holder of each outstanding security of the series affected. (Sections 513 and 1006) In order to determine whether the holders of the requisite principal amount of the outstanding debt securities have taken an action under the indenture as of a specified date: . the principal amount of an original issue discount security that will be deemed to be outstanding will be the amount of the principal that would be due and payable as of such date upon acceleration of the maturity to such date, . if, as of such date, the principal amount payable at the stated maturity of a debt security is not determinable, for example, because it is based on an index, the principal amount of such debt security deemed to be outstanding as of such date will be an amount determined in the manner prescribed for such debt security, 16

. the principal amount of a debt security denominated in one or more foreign currencies or currency units that will be deemed to be outstanding will be the $US equivalent, determined as of such date in the manner prescribed for such debt security, of the principal amount of such debt security or, in the case of a debt security described in the two preceding bullet points, of the amount described above, and . debt securities owned by us or any other obligor upon the debt securities or any of their affiliates will be disregarded and deemed not to be outstanding. Some debt securities, including those for whose payment or redemption money has been deposited or set aside in trust for the holders and those that have been fully defeased pursuant to Section 1402, will not be deemed to be outstanding. (Section 101) We will generally be entitled to set any day as a record date for determining the holders of outstanding debt securities of any series entitled to give or take any direction, notice, consent, waiver or other action under the indenture. In limited circumstances, the trustee will be entitled to set a record date for action by holders. If a record date is set for any action to be taken by holders of a particular series, the action may be taken only by persons who are holders of outstanding debt securities of that series on the record date. To be effective, the action must be taken by holders of the requisite principal amount of the debt securities within a specified period following the record date. For any particular record date, this period will be 180 days or such shorter period as we may specify, or the trustee may specify, if it set the record date. This period may be shortened or lengthened by not more than 180 days. (Section 104) Defeasance and Covenant Defeasance Unless we inform you otherwise in the prospectus supplement, the provisions of the indenture relating to defeasance and discharge of indebtedness, or defeasance of restrictive covenants, will apply to the debt securities of any series. (Section 1401) Defeasance and Discharge. Section 1402 of the indenture provides that we will be discharged from all of our obligations with respect to the debt securities, except for certain obligations to exchange or register the transfer of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and to hold moneys for payment in trust, upon the deposit in trust for the benefit of the holders of such debt securities of money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal, premium, if any, and interest on the debt securities on the respective stated maturities of the debt securities in accordance with the terms of the indenture and the debt securities. Such defeasance or discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge were not to occur. (Sections 1402 and 1404) Defeasance of Certain Covenants. Section 1403 of the indenture provides that, in certain circumstances, we may omit to comply with specified restrictive covenants, including any that we may describe in the prospectus supplement, and that in those circumstances the occurrence of certain events of default, which are described in the fourth bullet point above, with respect to such restrictive covenants, under "--Events of Default" and any that may be described in the prospectus supplement, will be deemed not to be or result in an event of default, in each case with respect to the debt securities. We, in order to exercise such option, will be required to deposit, in trust for the benefit of the holders of the debt securities, money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal, premium, if any, and interest on 17

the debt securities on the respective stated maturities in accordance with the terms of the indenture and the debt securities. We will also be required, among other things, to deliver to the trustee an opinion of counsel to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit and defeasance of certain obligations and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and defeasance were not to occur. In the event we exercise this option with respect to any debt securities and the debt securities were declared due and payable because of the occurrence of any event of default, the amount of money and U.S. government obligations so deposited in trust would be sufficient to pay amounts due on the debt securities at the time of their respective stated maturities, but might not be sufficient to pay amounts due on such debt securities upon any acceleration resulting from the event of default. In such case, we would remain liable for those payments. (Sections 1403 and 1404) Notices Holders will receive notices by mail at their addresses as they appear in the security register. (Sections 101 and 106) Title We may treat the person in whose name a debt security is registered on the applicable record date as the owner of the debt security for all purposes, whether or not it is overdue. (Section 309) Governing Law New York law will govern the indenture and the debt securities. (Section 112) Regarding the Trustee The trustee serves as trustee for: . our 6 1/2% Debentures due February 1, 2008, aggregating $300 million as of December 31, 2000, . our 6 3/8% Term Enhanced ReMarketable Securities, aggregating $500 million as of December 31, 2000, and . our 8.125% Notes due 2005, aggregating $325 million as of December 31, 2000. In addition, the trustee serves as trustee or fiscal agent for debt securities of our affiliates aggregating $3.3 billion as of December 31, 2000. We and our affiliates also maintain depository and other banking relationships with the trustee. Mr. R. Steve Letbetter, our Chairman, President and Chief Executive Officer, is a member of the Chase Texas Regional Advisory Board. The trustee and its affiliates are parties to credit agreements under which we and our affiliates have bank lines of credit. We and our affiliates maintain depository and other banking, investment banking, investment management and trust relationships with the trustee and its affiliates. 18

Plan of Distribution We may sell debt securities: . through an underwriter or underwriters, . through dealers, . through agents, . directly to purchasers, including our affiliates, or . through a combination of any of these methods. We may authorize underwriters, dealers and agents to solicit offers by institutions to purchase debt securities from us pursuant to delayed delivery contracts providing for payment and delivery on a specified date. If we elect to use delayed delivery contracts, we will describe the date of delivery, the conditions of the sale and the commissions payable for solicitation of such contracts in the prospectus supplement. We will describe the terms of any offering of debt securities in the prospectus supplement, including: . the method of distribution, . the name or names of any underwriters, dealers, purchasers or agents, and any managing underwriter or underwriters, . the purchase price of the debt securities and the proceeds we receive from the sale, . any underwriting discounts, agency fees or other form of underwriters' compensation, . any discounts and concessions allowed, reallowed or paid to dealers or agents, and . the expected time of delivery of the offered debt securities. We may change the initial public offering price and any discount or concessions allowed or reallowed to dealers from time to time. If we use underwriters to sell our debt securities, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters will be obligated to purchase all of the offered debt securities if any are purchased. In connection with the sale of debt securities, underwriters may receive compensation from us or from purchasers of debt securities for whom they may act as agents in the form of discounts, concessions or commissions. Underwriters may sell debt securities to or through dealers, and dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. If we use a dealer to sell debt securities, we will sell the debt securities to the dealer as principal. The dealer may then resell the debt securities to the public at varying prices to be determined by the dealer at the time of resale. These dealers may be deemed underwriters, as such term is defined in the Securities Act of 1933, of the debt securities they offer and sell. If we elect to use a dealer to sell debt securities, we will provide the name of the dealer and the terms of the transaction in the prospectus supplement. Debt securities may also be offered and sold in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act of 1933. 19

Underwriters, agents, dealers and some purchasers participating in the distribution of debt securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the debt securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933. Unless we inform you otherwise in the prospectus supplement, none of our directors, officers or employees will solicit or receive a commission in connection with direct sales by us of debt securities, although these persons may respond to inquiries by potential purchasers and perform ministerial and clerical work in connection with any such direct sales. We may enter into agreements with the underwriters, agents, purchasers, dealers or remarketing firms who participate in the distribution of our debt securities that will require us to indemnify them against specified liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments that they or any person controlling them may be required to make for those liabilities. Underwriters, agents, dealers or remarketing firms may be our customers. They may also engage in transactions with us or perform services for us or for our affiliates in the ordinary course of business. Each series of debt securities will be a new issue with no established trading market. We may elect to list any series of debt securities on an exchange. However, we are not obligated to do so. It is possible that one or more underwriters may make a market in a series of debt securities. However, they will not be obligated to do so and may discontinue market making at any time without notice. We cannot assure you that a liquid trading market for our debt securities will develop. In connection with an offering, the underwriters or agents may purchase and sell debt securities in the open market. These transactions may include over- allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. Stabilizing transactions consist of bids or purchases for the purpose of preventing or retarding a decline in the market price of the debt securities. Syndicate short positions involve the sale by the underwriters or agents of a greater number of debt securities than they are required to purchase from us in the offering. The underwriters also may impose a penalty bid, in which selling concessions allowed to syndicate members or other broker dealers in respect of the debt securities sold in the offering for their account may be reclaimed by the syndicate if the debt securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the debt securities, which may be higher than the price that might otherwise prevail in the open market, and these activities, if commenced, may be discontinued at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise. Validity of Securities The validity of our debt securities will be passed upon for us by Baker Botts L.L.P., Houston, Texas. Hugh Rice Kelly, Esq., our Executive Vice President, General Counsel and Secretary, or Rufus S. Scott, our Vice President, Deputy General Counsel and Assistant Secretary may pass upon other legal matters for us. Any underwriters will be advised about the validity of our debt securities and other legal matters by Dewey Ballantine LLP. James A.
