ABOUT CENTERPOINT ENERGY, INC. We are a public utility holding company. Our indirect wholly owned subsidiaries include (i) CenterPoint Energy Houston Electric, LLC ("CenterPoint Houston"), which provides electric transmission and distribution services in a 5,000-square-mile area of the Texas Gulf Coast that includes Houston, and (ii) CenterPoint Energy Resources Corp. ("CERC"), which owns gas distribution systems serving approximately three million customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma, and Texas. Through wholly owned subsidiaries, CERC also owns two interstate natural gas pipelines and gas gathering systems and provides various ancillary services. We also have an approximately 81% indirect ownership interest in Texas Genco Holdings, Inc. ("Texas Genco"), which owns and operates electric generating plants in Texas. We distributed approximately 19% of the outstanding common stock of Texas Genco to our shareholders in January 2003. On July 21, 2004, we announced a definitive agreement for the sale of our interest in Texas Genco. We currently expect that the sale of Texas Genco's non-nuclear assets and liabilities will occur during December 2004 and the sale of Texas Genco's nuclear assets and liabilities will occur in the first half of 2005. We are a registered public utility holding company under the Public Utility Holding Company Act of 1935, as amended ("1935 Act"). The 1935 Act and related rules and regulations impose a number of restrictions on our activities and those of our subsidiaries. The 1935 Act, among other things, limits our ability and the ability of our regulated subsidiaries to issue debt and equity securities without prior authorization, restricts the source of dividend payments to current and retained earnings without prior authorization, regulates sales and acquisitions of certain assets and businesses, and governs affiliate transactions. Our executive offices are located at 1111 Louisiana, Houston, Texas 77002, and our main telephone number at that address is 713-207-1111. 1

USE OF PROCEEDS We may satisfy purchases of common stock under the plan by: - issuing authorized but unissued shares of our common stock, - issuing shares of common stock held in our treasury, or - purchasing shares of common stock in the open market. Accordingly, the number of newly issued or treasury shares, if any, that we will ultimately sell under the plan is not currently known.

These purposes may include, but are not limited to: - working capital, - capital expenditures, - acquisitions, - the repayment or refinancing of debt or trust preferred securities, and - loans or advances to subsidiaries. We will not receive any proceeds when shares of common stock are purchased under the plan in the open market. 2

PLAN SUMMARY The following is a summary of the material provisions of the plan. This summary is not a complete description of all terms of the plan and is qualified in its entirety by reference to the plan. You should carefully review the summary below and the provisions of the plan that may be important to you before participating in the plan. ADMINISTRATION The plan is administered by the individual (who may be an employee of ours), bank, trust company or other entity, including us, whom we appoint from time to time to act as the administrator of the plan. As of the date of this prospectus, we are the administrator. The administrator administers the plan, receives cash from participants, holds participants' shares of common stock acquired under the plan, keeps records, sends statements of account activity to participants and performs other duties related to the plan. The administrator will forward funds that are to be used to purchase shares, and orders to sell shares, in the open market to an independent agent that we select and which is an "agent independent of the issuer," as that term is defined under the Securities Exchange Act of 1934. We reserve the right to continue serving as the administrator or to appoint another qualified person or entity to serve in that capacity. Participants may contact the administrator by writing, telephoning, or sending facsimiles to: CenterPoint Energy, Inc. Investor Services Department P. O. Box 4505 Houston, TX 77210 Telephone toll-free (business days from 8:00 a.m. to 5:00 p.m., Central Time): (800) 231-6406 nationally (713) 207-3060 in Houston Facsimile: (713) 207-3169 ELIGIBILITY Any person or entity, whether or not a record holder of common stock, is eligible to participate in the plan, provided that: - the person or entity fulfills the requirements of participation described below under "Enrollment Procedures," and - in the case of citizens or residents of a country other than the United States, its territories and possessions, participation would not violate local laws applicable to us, the plan and the participant. ENROLLMENT PROCEDURES After being furnished with a copy of this prospectus, eligible applicants may join the plan by returning a completed and signed enrollment form to the administrator and choosing one of the following options: - making an initial cash investment in the plan to purchase common stock of at least $250 for applicants who are not registered holders of eligible securities or $50 for applicants who are registered holders of eligible securities, - electing to have all or a part of cash dividends or interest payments on eligible securities reinvested into common stock, or - depositing certificates representing shares of common stock into the plan for safekeeping. 4

Applicants may obtain enrollment forms from the administrator upon written, facsimile or telephone request. Current registered holders of eligible securities should sign their name(s) on the enrollment form exactly as they appear on the certificates or instruments representing their eligible securities. A beneficial owner of eligible securities registered in street name (i.e., the name of a bank, broker or trustee) may participate in the plan by: - directing the financial intermediary to transfer eligible securities into the participant's name, and - depositing transferred shares of common stock into the plan for safekeeping and/or electing to reinvest cash dividends or interest payments on transferred eligible securities in common stock through the plan. Alternatively, the beneficial owner may make arrangements with the financial intermediary who is the registered holder to participate in the plan on behalf of the beneficial owner. To the extent required by applicable law in specified jurisdictions, including Alabama, Arizona, Arkansas, Delaware, Florida, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Mississippi, Montana, Nevada, New Hampshire, New Jersey, North Dakota, Puerto Rico, Rhode Island, South Carolina, Utah, Vermont, Virginia, Washington, West Virginia and Wyoming, we are offering shares of common stock under the plan to persons who are not presently record holders of our common stock only through a registered broker/dealer in those jurisdictions. An eligible applicant will become a participant as soon as practicable after the administrator has received and accepted a properly completed enrollment form. ELIGIBLE SECURITIES The equity and debt securities of CenterPoint Energy and our subsidiaries listed below are "eligible securities" for participation in the plan: - our common stock, and - CenterPoint Houston's First Mortgage Bonds, 9.15% Series due 2021. In addition, from time to time we may designate other equity or debt securities issued by us or our subsidiaries as eligible securities. INITIAL CASH INVESTMENTS AND ADDITIONAL CASH INVESTMENTS Interested investors, whether or not registered holders of eligible securities, may become participants by making an investment through the plan as described in this prospectus. To become a participant through a cash investment, an applicant who is not a registered holder of eligible securities must include a minimum initial cash investment of $250 with a completed enrollment form, while an applicant who is a registered holder of eligible securities must include a minimum initial cash investment of $50 with a completed enrollment form. Additional cash investments, which participants may make at their discretion, must be at least $50 for any single investment. However, cash investments in the aggregate, including both initial and additional cash investments, may not exceed $120,000 per account per calendar year. Participants may make cash investments by check or through automatic investing as described below under "Cash Investment Procedures." The administrator will make cash investments in our common stock beginning on the next investment date that is at least one business day after the administrator receives the funds and instructions. Cash investment funds, pending investment, will be credited to a participant's account and held in a trust account that is separated from our other funds. Cash investments not invested for a participant within 30 days of receipt will be promptly returned to the participant. NO INTEREST WILL BE PAID ON AMOUNTS HELD BY THE ADMINISTRATOR PENDING INVESTMENT. 5

A registered holder of eligible securities may invest cash payable to the registered holder as a result of the redemption, tender or maturity, including accrued interest and premium, if any, of eligible securities in common stock by delivering to the administrator an executed enrollment form designating such funds for investment. These funds will be treated as additional cash investments for purposes of determining whether the maximum annual limit of $120,000 per year has been reached. The administrator will return to a participant any cash investment that has not already been invested if it receives the participant's request to stop investment at least two business days prior to the applicable investment date. However, no refund of a check or money order will be made until the administrator has collected funds. Accordingly, refunds may take three weeks or more to be remitted. CASH INVESTMENT PROCEDURES Cash investments may be made by check or automatic deduction from predesignated bank accounts, as described below. Participants should NEVER SEND CASH for an investment. Investment by Check. Cash investments may be made by personal check or money order payable in U.S. dollars to CenterPoint Energy, Inc. Investor's Choice Plan and mailed to the administrator. Initial cash investments should be accompanied by enrollment forms while additional cash investments should be accompanied by the stub attached to each statement of account or transaction advice sent to participants. Automatic Investing. Participants may make automatic monthly or quarterly investments of a specified amount, not less than $50 per purchase nor more than $120,000 per calendar year, by electronic automatic transfer of funds from a predesignated bank account. To initiate automatic deductions, a participant must execute an automatic investing form that is available from the administrator and return it to the administrator, along with a voided check or deposit slip on the bank account from which funds are to be drawn. If the monthly investment option is chosen, automatic investing will begin on or about the 10th day of each month approximately 30 days after receipt of the authorization form. If the quarterly investment option is chosen, investments will begin on or about the 10th day of each March, June, September and December. In either case, automatic investing deductions will be made two business days before the investment date. A PARTICIPANT'S BANK MAY CHARGE THE PARTICIPANT A RETURNED CHECK FEE IF THE DESIGNATED BANK OR SAVINGS ACCOUNT DOES NOT HAVE SUFFICIENT FUNDS TO COVER THE AUTHORIZED DEDUCTION. Participants may change the amount of their automatic investment by notifying the administrator in writing or by facsimile of the new amount, and the change will take place approximately two weeks after the notice is received. Similarly, a participant may cancel automatic investing by instructing the administrator in writing or by facsimile. Cancellation will be effective approximately two weeks after the notice is received. To change a designated bank account, a participant must notify the administrator in writing at least 30 days before the change is to take effect and supply a voided check or deposit slip for the new account. All cash investments are subject to collection by the administrator for full face value in U.S. funds. The method of delivery of any cash investment is at the election and risk of the investor and will be deemed received when actually received by the administrator. If the delivery is by mail, we recommend that the participant use properly insured, registered mail with return receipt requested, and that the mailing be made sufficiently in advance of the appropriate investment date. INVESTMENT DATES The plan's "investment dates" occur at least once every five business days. However, purchases will be made every business day when deemed practicable by the administrator. A participant's cash investment will generally be invested within five business days of receipt. For exceptions under specified circumstances involving open market purchases, see "Source and Price of Shares" below. 6

DIVIDEND AND INTEREST PAYMENT OPTIONS The plan offers participants the option of reinvesting cash dividends and interest payments paid on their eligible securities in common stock. With respect to cash dividends on common stock for which reinvestment is not elected, the plan offers the option of direct deposit or check payment, as described below. Reinvestment of Cash Dividends and Interest Payments. Participants may elect to reinvest all or part of the cash dividends and interest payments on eligible securities registered in their names by making the election on their initial enrollment forms or by delivering written or facsimile instructions to the administrator. Participants electing partial reinvestment of cash dividends and interest payments must designate the specific security or securities for which partial reinvestment is desired and the number of whole shares or the whole dollar amount they want to be reinvested. The amount reinvested will be reduced by any amount required to be withheld under any applicable tax or other statutes. Cash dividends and interest payments not being reinvested will be sent to the participant by direct deposit or check, as appropriate. A participant may change reinvestment amounts and the eligible securities on which cash dividend or interest payments are reinvested from time to time by delivering a new enrollment form or written or facsimile instructions to the administrator. To be effective for a particular payment, the administrator must receive instructions of such change on or before the record date of the dividend or interest payment. Record dates are usually the 16th day of the month preceding a payment date. The record date for common stock dividends is usually the 16th day of each February, May, August and November. Dividends and interest payments will be invested beginning either on the date of payment, if the payment date is an investment date, or on the first investment date following payment. Dividend and interest payments not invested within 30 days of receipt will be returned promptly to the participant. Funds pending investment will be credited to a participant's account and held in a trust account that will be separated from any of our other funds or monies. NO INTEREST WILL BE PAID ON FUNDS HELD BY THE ADMINISTRATOR PENDING INVESTMENT. Direct Deposit of Dividends on Common Stock. Through the plan's direct deposit feature, a participant may elect to have any cash dividends on common stock automatically deposited into a designated bank or savings account. The cash dividends will be deposited on the dividend payment date. Participants who wish to have dividends automatically deposited must execute a direct deposit authorization form that is available from the administrator and send it to the administrator, along with a voided check or deposit slip for the designated bank account. The administrator must receive direct deposit authorization at least 30 days before an applicable common stock dividend payment date to be effective for that payment date. Participants can cancel direct deposit of dividends by notifying the administrator in writing or by facsimile. In order to be effective for an applicable dividend payment date, the administrator must receive the cancellation notice at least 30 days before that dividend payment date. To change a designated bank account for direct deposit of dividends, the administrator must receive written notice, accompanied by a voided check or deposit slip for the new bank account, at least 30 days before an applicable dividend payment date. Check Payments of Dividends and Interest Payments. Cash dividends and interest payments on eligible securities not designated for reinvestment or direct deposit will be paid by check to the participant. A check for the amount of funds payable will be sent through the mail so that it will reach the participant as close as possible to the dividend or interest payment date. SOURCE AND PRICE OF SHARES To fulfill plan requirements, shares of common stock will be, at our discretion, purchased either directly from us or on the open market by an independent agent. Shares purchased from us will be either authorized but unissued shares or shares held in our treasury. Purchases of common stock under the plan are subject to such terms and conditions, including price and delivery, as the administrator may accept. 7

Purchases from CenterPoint Energy. The price of common stock purchased from us will be the average of the high and low sales price of the common stock reported on the New York Stock Exchange Composite Tape as published in The Wall Street Journal for the trading day immediately preceding the relevant investment date, and the purchase will be made on the investment date. In the event no trading is reported for the relevant trading day, we may determine the purchase price on the basis of market quotations we deem appropriate. No brokerage fee will be charged on shares acquired directly from us. Open Market Purchases and Sales. The price of common stock purchased or sold on the open market will be the weighted average price of all shares purchased or sold, as the case may be, through the plan for the investment date. The weighted average price will be increased for brokerage fees and commissions, any related service charges and applicable taxes. As of the date of this prospectus, we do not expect the brokerage fees and commissions and related service charges to exceed $0.10 per share. An independent agent will make purchases and sales of common stock on the open market beginning on the relevant investment date. These purchases and sales will be completed not later than five days from that date, except where completion at a later date is necessary or advisable under any applicable laws or regulations. Funds not invested within 30 days of receipt will be returned promptly to participants. The independent agent will make purchases and sales on any securities exchange where shares of common stock are traded, in the over-the-counter market, or by negotiated transactions. These purchases and sales may be subject to such terms and conditions regarding price, delivery and other terms as agreed to by the administrator. The independent agent will have sole authority to direct the time or price at which shares may be purchased or sold, the markets on which the shares are to be purchased or sold, and the selection of the broker or dealer, other than the independent agent, through or from whom purchases or sales are to be made. The independent agent may commingle each participant's funds with those of other participants for the purchases and sales of common stock but will hold the funds at all times in a separate trust account apart from our funds. The number of shares, including any fraction of a share rounded to three decimal places, of common stock credited to a participant's account for a particular investment date will be determined by dividing the total amount of cash dividends, interest payments and/or cash investments to be invested for the participant on the investment date by the relevant purchase price per share. Dividend and voting rights will commence upon settlement, whether shares are purchased from us or on the open market. SAFEKEEPING SERVICE Participants may use the plan's free safekeeping service at any time. Participants may deposit common stock into the plan by delivering the stock certificates without endorsement to the administrator. Shares deposited in the plan for safekeeping will be transferred into the name of the administrator or its nominee and credited to the participant's account under the plan. Thereafter, the shares will be treated in the same manner as shares purchased through the plan. Because shares deposited for safekeeping are treated in the same manner as shares purchased through the plan, they may be efficiently and economically transferred or sold if the participant desires. SALE OF COMMON STOCK Participants may request the administrator to sell any number of whole shares held in their accounts at any time by written, telephone or facsimile instructions. As soon as practicable after receipt of the request, but within five business days, the administrator will instruct the independent agent to sell the shares. The independent agent will sell the shares as soon as practicable thereafter. Proceeds of the sale, less applicable brokerage fees and commissions and service charges and any applicable taxes, will be sent to the participant within five business days after the independent agent has completed the sale. The sales price will be determined in the same way as the price for shares of common stock purchased for participants on the open market. See "Source and Price of Shares" above. If the administrator receives a request between the record date and the dividend payment date to sell shares on which dividends are not 8

being reinvested, the sale will be made within five days after receipt of the request and the proceeds from the sale will be sent to the participant. Cash dividends will be paid in the usual manner on the dividend payment date. If the administrator receives a request between the record date and the dividend payment date to sell shares on which all or a portion of the dividends are being reinvested, the dividends on those shares will be reinvested on the investment date and newly purchased shares will be credited to the participant's account. If the request for sale does not include all shares in the participant's account, the number of shares requested will be sold within five days after receipt of the request and the proceeds from the sale will be sent to the participant. Newly purchased shares will be retained in the participant's account after the investment date. If the request for sale covers all shares in the participant's account, the sale will be delayed until after the dividend payment date and all shares, including newly purchased shares, will be sold within five days after the investment date and the proceeds from the sale will be sent to the participant. If a participant wishes to sell shares held in the participant's account through a broker, the participant may request the administrator to issue a certificate for a specific number of whole shares by written, telephone or facsimile instruction. A certificate will be sent to the participant within two business days after receipt of the request. WITHDRAWAL, TRANSFERS, AND GIFTS OF COMMON STOCK Withdrawals and Transfers Outside the Plan. A participant may withdraw shares of common stock credited to the participant's plan account if the participant will continue to be the record holder after withdrawal. A participant may do so by instructing the administrator in writing, by telephone or by facsimile or, if the participant will not be the record holder after withdrawal, by delivering written instructions, specifying the recipient's name, address, Social Security number and telephone number and a stock assignment or stock power, with the participant's signature guaranteed by a member of the Medallion Signature Guarantee program (a participating broker, bank, savings and loan association, etc.). If shares are to be sent to a broker, the participant must provide in writing the number of whole shares to be withdrawn, the broker's name, business name, address, telephone number, and the brokerage account number, if applicable. Certificates representing whole shares withdrawn from the plan will be mailed to the participant or designated recipient within two business days of receipt of a properly documented request. Withdrawal of shares of common stock does not affect reinvestment of cash dividends on the shares withdrawn unless: - the participant is no longer the record holder of the shares, - the participant specifically discontinues the reinvestment, or - the participant terminates participation in the plan. If the administrator receives a request between the record date and the dividend payment date to withdraw shares on which dividends are not reinvested, the withdrawal will be made within five days after receipt of the request and dividends will be deposited in the account of the participant holding the shares prior to the withdrawal, in the usual manner, on the dividend payment date. If the administrator receives a request between the record date and the dividend payment date to withdraw shares on which all or a portion of the dividends are reinvested, the dividends on those shares will be reinvested on the investment date and newly purchased shares will be credited to the participant's account. If the request for withdrawal does not include all shares in the participant's account, the number of shares requested will be withdrawn within two business days after receipt of the request and sent to the designated recipient. Newly purchased shares will be retained in the account of the participant making the request. If the request for withdrawal covers all shares in the participant's account, the withdrawal will be delayed until after the dividend payment date and all shares, including newly purchased shares, will be withdrawn within two business days after the investment date. All shares in the participant's account will be sent to the designated recipient. 9

Gifts and Transfers of Common Stock Within the Plan. If a participant wishes to transfer all or a part of the participant's shares to a plan account for another person, whether by gift, private sale or otherwise, the participant may effect the transfer by giving transfer instructions, in writing, to the administrator. Transfers of less than all of the shares in the participant's account must be made in whole share amounts. Requests for such transfers are subject to the same requirements applicable to transfers of common stock generally, including the requirement of a stock power with a Medallion Signature Guarantee. The transfer will be effected as soon as practicable following the administrator's receipt of the required documentation. Gifts and transfers within the plan are subject to the same provisions as described above under "Withdrawals and Transfers Outside the Plan." The administrator will continue to hold under the plan shares that are transferred within the plan. If the transferee is not already a participant, a plan account will be opened in the name of the transferee, and the transferee will automatically receive an enrollment form to elect any applicable services offered through the plan. Until the transferee elects otherwise or the transferor specifically requests that the new account be enrolled in one or more of the plan's options, such as dividend reinvestment, the transferee account will be treated as having elected only to have shares held in safekeeping under the plan. If the transferee is already a participant, the shares transferred will be treated as other shares already in the account of the transferee with respect to plan options. As a result of the transfer, the transferor and the transferee will receive a statement confirming the transaction. The transferor may request that a holiday or all occasion gift certificate be provided, either to the transferor for personal delivery to the transferee or directly to the transferee, in connection with a transfer. REINVESTMENT OF DIVIDENDS ON REMAINING SHARES When a participant sells, withdraws or transfers a portion of the shares credited to the participant's account, the number of shares credited to the account is reduced. For a participant who is reinvesting cash dividends paid on only a portion of the shares credited to the participant's account, unless the participant gives specific instructions to the contrary, the reduction will first be made to the number of shares for which reinvestment has not been elected before it is made to the number of shares for which reinvestment has been elected. Accordingly, after the sale, withdrawal or transfer, reinvestment of cash dividends will continue on the remaining shares credited to the participant's account up to the number of shares designated for reinvestment prior to the sale, withdrawal or transfer. For example, if a participant who had elected to have cash dividends reinvested on 50 shares of a total of 100 shares credited to the participant's account elected to sell, withdraw or transfer 25 shares, cash dividends on 50 shares of the remaining 75 shares credited to the account would be reinvested through the plan. If instead the participant elected to sell, withdraw or transfer 75 shares, cash dividends on the remaining 25 shares credited to the participant's account would be reinvested through the plan. REPORTS TO PARTICIPANTS The administrator will send each participant a quarterly statement of year-to-date activity showing the amount invested, purchase price, the number of shares purchased, deposited, sold, transferred and withdrawn, total shares accumulated and other information. The administrator will also send each participant a confirmation promptly after each cash investment, deposit, sale, withdrawal or transfer. Dividend and interest reinvestments will not be individually confirmed, but rather will appear on the quarterly statement. Participants should retain statements and confirmations in their permanent records to establish the cost basis of shares purchased under the plan for income tax and other purposes. The administrator will send each participant copies of all communications sent to holders of common stock, including our annual report to shareholders, notice of our annual meeting, proxy statement and form of proxy, as well as federal tax reporting statements, if applicable, for reporting taxable income received from us. 10

The administrator will send all payments, notices, statements and reports to the participant's address on the administrator's records. It is therefore imperative that participants promptly notify the administrator of any change of address. CERTIFICATES FOR SHARES The administrator will hold shares of common stock purchased under, or deposited for safekeeping into, the plan and credited to participants' accounts in an automated electronic record keeping system in the administrator's name or the name of its nominee, as custodian. The number of shares, including fractional shares, held for each participant will be shown on each statement of account. A participant may obtain a certificate for all or part of the whole shares held in the participant's account at any time upon a written, telephone or facsimile request to the administrator. Requested certificates will be mailed, free of charge, to the participant within two business days after the administrator receives the request. The administrator will continue to hold any remaining whole or fractional shares in the participant's account. Shares held in a participant's account cannot be pledged or assigned. A participant who wishes to pledge or assign any shares must request that they be withdrawn and issued to the participant in certificate form. Certificates for fractional shares of common stock will not be issued under any circumstances. TERMINATION OF PARTICIPATION A participant may terminate participation in the plan at any time by notifying the administrator in writing, by telephone or by facsimile. As soon as practicable after receipt of notification, the administrator will mail the participant: - a certificate for all of the whole shares credited to the participant's account, - any dividends, interest payments and cash investments credited to the participant's account, and - a check for the cash value of any fraction of a share of common stock credited to the participant's account. A fraction of a share will be valued at the average of the high and low sales prices of the common stock reported on the New York Stock Exchange Composite Tape as published in The Wall Street Journal for the trading day preceding the date of termination. COSTS We will pay all administrative costs and expenses of the plan. PARTICIPANTS WILL BEAR THE COST OF BROKERAGE FEES AND COMMISSIONS, RELATED SERVICE CHARGES AND ANY APPLICABLE TAXES INCURRED ON ALL PURCHASES AND SALES OF COMMON STOCK ON THE OPEN MARKET. These costs will be included as adjustments to the purchase and sale prices. As of the date of this prospectus, shares of stock are being purchased directly from us. There are no brokerage fees and commissions or related service charges for shares of common stock purchased directly from us. FEDERAL INCOME TAX CONSEQUENCES THE FOLLOWING IS A SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATING IN THE PLAN. TAX CONSEQUENCES WILL VARY AMONG PARTICIPANTS DEPENDING UPON INDIVIDUAL CIRCUMSTANCES AND STATE, LOCAL AND FOREIGN LAWS. EACH PARTICIPANT SHOULD CONSULT THE PARTICIPANT'S OWN TAX ADVISOR REGARDING THE TAX CONSEQUENCES FOR THE PARTICIPANT AS A RESULT OF PARTICIPATING IN THE PLAN. A participant will be required to include as income for federal income tax purposes the gross amount of all dividends and interest payments, including any original issue discount, on eligible securities reinvested in common stock as though the participant received the dividends and interest payments in 11

cash. In addition, a participant will be taxed on any brokerage commissions, fees or service charges that we pay for in connection with a purchase of our common stock for the participant under the plan. To the extent distributions by us to our participants are treated as made from our current or accumulated earnings and profits, the distributions will be dividends taxable as ordinary income. The amount of any dividends in excess of earnings and profits will reduce a participant's tax basis in the common stock with respect to which the dividend was received, and, to the extent in excess of basis, result in capital gain. As a general rule, a participant's tax basis for shares of common stock (or any fraction of a share) acquired under the plan, will be equal to the cash value of dividends and interest payments attributable to the purchase of the shares on the applicable purchase date, as adjusted for brokerage commissions and fees, services charges and applicable taxes, if any. A participant's tax basis in shares purchased with cash investments will be the cost of the shares plus any allocable brokerage commissions or fees, service charges and applicable taxes on the applicable purchase date. Shares of common stock purchased under the plan will have a holding period beginning on the day after the applicable purchase date. A participant will not realize any taxable income when the participant receives certificates for whole shares credited to an account under the plan. The participant will recognize gain or loss upon the sale of whole shares and upon the sale of any fractional shares credited to the participant's account under the plan. The gain or loss will be equal to the difference between the amount received for shares (or a fractional share) and the participant's tax basis in such shares. Under Internal Revenue Service backup withholding regulations, dividends and interest payments reinvested under the plan may be subject to the withholding tax generally applicable to dividends and interest payments unless the participant provides the administrator with the participant's taxpayer identification number (in the case of individual taxpayers the taxpayer identification number is their Social Security number). Any amount so withheld will be treated as taxable income received by the participant and will be reflected on Forms 1099-DIV and 1099-INT mailed annually to all our investors, including plan participants. STOCK SPLITS, STOCK DIVIDENDS, AND RIGHTS OFFERINGS Any shares or other noncash distributions, including stock splits, stock dividends, combinations, recapitalizations and similar events affecting our common stock, will be credited to a participant's account on a pro-rata basis. In the event of a rights offering, a participant will receive rights based upon the total number of whole shares of common stock credited to the participant's account. VOTING OF PROXIES Participants have the exclusive right to vote all whole shares credited to their plan accounts, either in person or by proxy, at any annual or special meeting of our shareholders. Fractions of shares cannot be voted. The administrator will forward to each participant all shareholder materials relating to shares credited to that participant's account. LIMITATION OF LIABILITY Neither we nor the administrator nor any independent agent will be liable for any act done in good faith or for any good faith omission to act, including, without limitation, any claim of liability arising from failure to terminate a participant's account upon the participant's death prior to receipt of notice in writing of such death, or with respect to the prices or times at which shares of common stock are purchased or sold for participants, or fluctuations in the market value of common stock. WRITTEN PROVISIONS OF THE PLAN CONTROLLING With respect to any matter relating to the plan, including, without limitation, the timing and pricing of purchases and sales of common stock for participants, the written provisions of the plan are controlling. 12

Participants should not rely on any oral representations inconsistent with the written provisions of the plan. Neither we nor the administrator nor any independent agent will be liable for a participant's reliance on oral statements inconsistent with the written provisions of the plan. INTERPRETATION AND REGULATION OF THE PLAN Our officers are authorized to take actions to carry out the plan consistent with the plan's terms and conditions. We reserve the right to interpret and regulate the plan as we deem desirable or necessary in connection with the plan's operations. CHANGE OR TERMINATION OF THE PLAN We may suspend, modify or terminate the plan at any time, in whole, in part or in respect of participants in one or more jurisdictions, without the approval of participants. Notice of suspension, modification or termination will be sent to all affected participants. Upon any whole or partial termination of the plan by us, each affected participant will receive: - a certificate for all of the whole shares credited to the participant's account, - any dividends, interest payments and cash investments credited to the participant's account, and - a check for the cash value of any fraction of a share of common stock credited to the participant's account. A fraction of a share will be valued at the average of the high and low sales prices of the common stock reported on the New York Stock Exchange Composite Tape as published in The Wall Street Journal for the trading day preceding the date of termination. TERMINATION OF PARTICIPATION BY CENTERPOINT ENERGY If a participant does not have at least one whole share of common stock registered in the participant's name or credited to the participant's account, or does not own any eligible securities for which cash dividends or interest payments are designated for reinvestment under the plan, we may terminate the participant's participation in the plan upon written notice. Additionally, we may terminate any participant's participation in the plan after written notice mailed in advance to the participant's address appearing on the records of the administrator. A participant whose participation has been terminated will receive: - a certificate for all of the whole shares credited to the participant's account, - any dividends, interest payments and cash investments credited to the participant's account, and - a check for the cash value of any fraction of a share of common stock credited to the participant's account. A fraction of a share will be valued at the average of the high and low sales prices of the common stock reported on the New York Stock Exchange Composite Tape as published in The Wall Street Journal for the trading day preceding the date of termination. 13

PLAN OF DISTRIBUTION We are offering common stock by this prospectus pursuant to the plan. The terms of the plan provide for the purchase of shares of our common stock directly from us or, at our option, by an independent agent on the open market. As of the date of this prospectus, shares of common stock purchased for participants under the plan are being purchased directly from us. The plan provides that we may not change our determination regarding the source of purchases of shares more than once in any three-month period. We expect our primary consideration in determining the source of shares to be used for purchases under the plan will be our need to increase equity capital. If we do not need to raise funds externally or if financing needs are satisfied using non-equity sources of funds to maintain our targeted capital structure, shares of common stock purchased for participants will be purchased in the open market, subject to the limitation on changing the source of shares of common stock. We will pay all administrative costs and expenses associated with the plan. Participants will bear the cost of brokerage commissions and fees, related service charges and any applicable taxes incurred on all purchases and sales made in the open market. These costs will be included as adjustments to purchase and sales prices. There are no brokerage fees and commissions or related service charges for shares of common stock purchased directly from us. DESCRIPTION OF OUR CAPITAL STOCK As of December 1, 2004, our authorized capital stock consisted of: - 1,000,000,000 shares of common stock, par value $0.01 per share, of which approximately 307,860,111 shares were outstanding, excluding 166 shares held as treasury stock, and - 20,000,000 shares of preferred stock, par value $0.01 per share, of which 1,000,000 shares are classified as Series A preferred stock, none of which was outstanding. Each share of our common stock offered by means of this prospectus includes an associated preferred stock purchase right. The shares of Series A preferred stock have been initially reserved for issuance upon exercise of the rights. We have incorporated by reference the descriptions of our common stock and associated rights into this prospectus. Please read "Where You Can Find More Information." 14

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Article 2.02.A.(16) and Article 2.02-1 of the Texas Business Corporation Act and Article V of the Company's Amended and Restated Bylaws provide the Company with broad powers and authority to indemnify its directors and officers and to purchase and maintain insurance for such purposes. Pursuant to such statutory and Bylaw provisions, the Company has purchased insurance against certain costs of indemnification that may be incurred by it and by its officers and directors. Additionally, Article IX of the Company's Amended and Restated Articles of Incorporation provides that a director of the Company is not liable to the Company for monetary damages for any act or omission in the director's capacity as director, except that Article IX does not eliminate or limit the liability of a director for (i) any breach of such director's duty of loyalty to the Company or its shareholders, (ii) any act or omission not in good faith that constitutes a breach of duty of such director to the Company or an act or omission that involves intentional misconduct or a knowing violation of law, (iii) a transaction from which such director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office or (iv) an act or omission for which the liability of a director is expressly provided for by statute. Article IX also provides that any subsequent amendments to Texas statutes that further limit the liability of directors will inure to the benefit of the directors, without any further action by shareholders. Any repeal or modification of Article IX shall not adversely affect any right of protection of a director of the Company existing at the time of the repeal or modification. See "Item 17. Undertakings" for a description of the SEC's position regarding such indemnification provisions. II-1

(a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually II-2

or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) of the Securities Act of 1933 if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-3 or Form S-8 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3
