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. On May 19, 2003, the Company issued $575 million aggregate principal amount of convertible senior notes due May 15, 2023 with an interest rate of 3.75%. Holders may convert each of their notes into shares of CenterPoint common stock, initially at a conversion rate of 86.3558 shares of common stock per $1,000 principal amount of notes at any time prior to maturity, under the following circumstances: (1) if the last reported sale price of CenterPoint common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the previous calendar quarter is greater than or equal to 120% or, following May 15, 2008, 110% of the conversion price per share of CenterPoint common stock on such last trading day, (2) if the notes have been called for redemption, (3) during any period in which the credit ratings assigned to the notes by both Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies, are lower than Ba2 and BB, respectively, or the notes are no longer rated by at least one of these ratings services or their successors, or (4) upon the occurrence of specified corporate transactions, including the distribution to all holders of CenterPoint common stock of certain rights entitling them to purchase shares of CenterPoint common stock at less than the last reported sale price of a share of CenterPoint common stock on the trading day prior to the declaration date of the distribution or the distribution to all holders of CenterPoint common stock of the Company's assets, debt securities or certain rights to purchase the Company's securities, which distribution has a per share value exceeding 15% of the last reported sale price of a share of CenterPoint common stock on the trading day immediately preceding the declaration date for such distribution. The convertible senior notes also have a contingent interest feature requiring contingent interest to be paid to holders of notes commencing on or after May 15, 2008, in the event that the average trading price of a note for the applicable five trading day period equals or exceeds 120% of the principal amount of the note as of the day immediately preceding the first day of the applicable six-month interest period. Contingent interest will be equal to 0.25% of the average trading price of the note for the applicable five trading day period. Proceeds from the issuance of the convertible senior notes were used for the Term Loan Reduction and to repay revolver borrowings under the Company's bank facility in the amount of $557 million (term loan reduction) and $0.75 million (revolver reduction). On May 27, 2003, the Company issued $400 million aggregate principal amount of senior notes composed of $200 million principal amount of 5-year notes with an 3

interest rate of 5.875% and $200 million principal amount of 12-year notes with an interest rate of 6.85%. Proceeds in the amount of $397 million were used to reduce the term loan component of the Company's bank facility. On May 28, 2003, the Company granted the banks a security interest in its 81% stock ownership of Texas Genco. Granting the security interest in the stock of Texas Genco eliminated a 25 basis point increase in the borrowing costs under the bank facility that would have been effective after May 28, 2003. The security interest is to be released at the time of the sale of Texas Genco. In July 2003, the Company remarketed two series of insurance-backed pollution control bonds aggregating $150.9 million, reducing the interest rate from 5.8% to 4%. Of the total amount of bonds remarketed, $92.0 million mature on August 1, 2015 and $58.9 million mature on October 15, 2015. None of the Company's debt is classified as short-term debt. 6.

On April 14, 2003, CenterPoint Energy Resources Corp. ("GasCo") issued $112 million 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 GasCo's 6 3/8% Term Enhanced ReMarketable Securities ("TERMS") and to pay costs associated with the refinancing. On May 23, 2003, CenterPoint Energy Houston Electric, LLC (the "T&D Utility") issued $200 million aggregate principal amount of 20-year general mortgage bonds with an interest rate of 5.6%. Proceeds were used to redeem, on July 1, 2003, $200 million aggregate principal amount of the T&D Utility's 7.5% first mortgage bonds due 2023 at 103.51% of their principal amount. Funds for the redemption were deposited in trust on May 23, 2003, and the first mortgage bonds were legally extinguished. As of June 30, 2003, GasCo had a revolving credit facility that provided for an aggregate of $200 million in committed credit. As of June 30, 2003, this revolving credit facility was not utilized. This revolving credit facility terminates on March 23, 2004. 4

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. The revolving credit facility contains various business and financial covenants. For the aggregate amount of short-term debt outstanding as of the end of the quarter for the Utility Subsidiaries, as well as the weighted average interest rate for such short-term debt as of such date, see Exhibit E hereto. 7.

Financing Subsidiaries may be corporations, trusts, partnerships or other entities created specifically for the purposes described in the Order. The amount of securities issued by the Financing Subsidiaries to third parties will count toward the respective financing limits of its immediate parent. Applicants anticipate that the Financing Subsidiaries will be wholly-owned indirect subsidiaries of CenterPoint and fully consolidated for purposes of financial reporting. Such financing subsidiaries shall be organized only if, in management's opinion, the creation and utilization of such financing subsidiary will likely result in tax savings, increased access to capital markets and/or lower cost of capital for the Company or its subsidiaries. 17.
