Investor's Choice offers a number of convenient options for investing in shares of Common Stock, including through reinvestment of all or a portion of the cash dividends paid and interest payments made on certain securities of the Company and its subsidiaries (the "Eligible Securities"). Shares of Common Stock will be purchased under the Plan, at the option of the Company, from newly issued shares, shares held in the treasury of the Company or shares purchased on the open market. Any open market purchases will be made through an Independent Agent (as defined below) selected by the Company. The Common Stock is listed on the New York and the Chicago Stock Exchanges. The closing price of the Common Stock on May 25, 1999 on the New York Stock Exchange was $31.69. The purchase price of newly issued or treasury shares of Common Stock purchased under the Plan for a particular Investment Date (as defined below) will be the average of the high and low sales prices for the Common Stock reported on the New York Stock Exchange Composite Tape as published in The Wall Street Journal for the trading day preceding that Investment Date. The price of shares of Common Stock purchased or sold in the open market will be the aggregate weighted average price per share (adjusted for brokerage fees and commissions, any service charges and applicable taxes) of the aggregate number of shares purchased or sold during the relevant period. There will be no discount from the purchase price for shares purchased under the Plan. The Company will pay the costs of administration of the Plan, except that participants in the Plan ("Participants") will bear the cost of brokerage fees and commissions, any services charges and applicable taxes related to shares purchased or sold on the open market. To the extent required by applicable law in certain jurisdictions, including Arizona, Florida, Maine, Nebraska, North Carolina, North Dakota, Oklahoma and Vermont, shares of Common Stock offered under Investor's Choice to persons who are not presently record holders of Common Stock are offered only through a registered broker/dealer in those jurisdictions.

Plan Summary The following summary of the Investor's Choice Plan is not a complete description of all terms and provisions of the Plan. The summary is qualified in its entirety by reference to all of the terms and provisions of the Plan. For more details, see a copy of the Plan, which is filed as an exhibit to the Registration Statement. Administration Administration of the Plan is conducted by the individual (who may be an employee of the Company), bank, trust company or other entity (including the Company) appointed from time to time by the Company to act as administrator of Investor's Choice (the "Administrator"). As of the date of this Prospectus, the Company is 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 agent selected by the Company (an "Independent Agent") that is an "agent independent of the issuer," as that term is defined under the Exchange Act. The Company reserves the right to continue serving as the Administrator or appoint another qualified person or entity to serve in that capacity. Additionally, as discussed below under "Individual Retirement Account," First Trust Corporation has been appointed by the Company to act as the Trustee for Investor's Choice Individual Retirement Accounts (the "IRA Trustee"). The IRA Trustee maintains all investment records, provides quarterly reports to each IRA Participant (as defined below) and makes all Internal Revenue Service reports to each IRA Participant. 5

Participants may contact the Administrator or the IRA Trustee by writing, telephoning or sending facsimiles to: THE ADMINISTRATOR: Reliant Energy, Incorporated Investor Services Department P. O.

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 Investor's Choice by (i) directing the financial intermediary to transfer Eligible Securities into the Participant's name and (ii) 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 Investor's Choice on behalf of the beneficial owner. 6

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 following equity and debt securities of the Company are Eligible Securities for participation in Investor's Choice: . Common Stock . Debentures, 9 3/8% Series due June 1, 2001 . Debentures, 7 7/8% Series due July 1, 2002 . $4 Preferred Stock . First Mortgage Bonds, 9.15% Series due 2021 . First Mortgage Bonds, 8 3/4% Series due 2022 . First Mortgage Bonds, 7 3/4% Series due 2023 . First Mortgage Bonds, 7 1/2% Series due 2023 In addition, the Company from time to time may designate other equity or debt securities of the Company and its subsidiaries as Eligible Securities. Initial 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 herein. 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 at least $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 at least $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. Cash investments may be paid by check or through automatic investing as described below under "Cash Investment Procedures." The Administrator will invest cash investments in 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 which is separated from other funds of the Company. 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. A registered holder of Eligible Securities may invest in Common Stock the cash payable, including accrued interest and premium, if any, as a result of the redemption, tender or maturity of Eligible Securities by delivering to the Administrator an executed Enrollment Form designating such funds for investment. Such 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. 7

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 funds have been collected by the Administrator. Accordingly, such refunds may take up to 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. Check Investment. Cash investments may be made by personal check or money order payable in U.S. dollars to Reliant Energy, Incorporated 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. Investor's Choice 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 (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 investment every month is chosen, automatic investing will begin on or about the 10th of each month approximately 30 days after receipt of the authorization form. If quarterly investment is chosen, investments will begin on or about the 10th 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 WILL BE CHARGED A RETURNED CHECK FEE BY THE BANK 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. 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. The 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, it is recommended that the investor 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 certain circumstances involving open market purchases, see "Source and Price of Shares" below. 8

Dividend and Interest Payment Options Investor's Choice 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, Investor's Choice 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 such election on their initial Enrollment Form 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 15th of the month preceding a payment date. The record date for Common Stock dividends is usually the 15th 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 which will be separated from any other funds or monies of the Company. 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. Such 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 (available from the Administrator) and send it to the Administrator along with a voided check or deposit slip for the designated bank account. Direct deposit authorization must be received by the Administrator 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 9

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 the Company's discretion, purchased either directly from the Company (in which case shares will be either authorized but unissued shares or shares held in the treasury of the Company) or on the open market by an Independent Agent. The purchases of Common Stock are subject to such terms and conditions, including price and delivery, as the Administrator may accept. Purchases from the Company. The price of Common Stock purchased from the Company, either authorized but unissued shares or shares held in the treasury of the Company, will be 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 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 trading day, the purchase price may be determined by the Company on the basis of market quotations it deems appropriate. No brokerage fee will be charged on shares acquired directly from the Company. Open Market Purchases and Sales. The price of Common Stock purchased or sold on the open market will be the weighted average price (increased for brokerage fees and commissions, any related service charges and applicable taxes) of all shares purchased or sold, as the case may be, through the Plan for the Investment Date. As of the date of this Prospectus, brokerage fees and commission and related service charges are not expected to exceed ten cents per share. Purchases and sales of Common Stock on the open market will be made by an Independent Agent beginning on the relevant Investment Date and will be completed not later than five days after such 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. Purchases and sales may be made on any securities exchange where shares of Common Stock are traded, in the over-the-counter market, or by negotiated transactions, and 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 such funds at all times in a separate trust account apart from the funds of the Company. 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 the Company 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 10

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, such shares will be treated in the same manner as shares purchased through the Plan. By using the Plan's safekeeping service, Participants no longer bear the risk of loss, theft or destruction of the certificates. Also, 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, and 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 (as of the date of this Prospectus less than ten cents per share) and any applicable taxes, will be sent to the Participant within five business days after the sale has been completed by the Independent Agent. 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 for explanation. If the Administrator receives a request to sell shares (on which dividends are not being reinvested) between the record date and the dividend payment date, 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 to sell shares (on which all or a portion of the dividends is being reinvested) between the record date and the dividend payment date, 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 acquired shares, will be sold within five days after the Investment Date and the proceeds from the sale will be sent to the Participant. 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 so long as the Participant will continue to be the record holder after withdrawal, 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 (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 transferred, 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 (i) the Participant is no longer the record holder of such shares, (ii) the reinvestment is specifically discontinued by the Participant or (iii) the Participant terminates participation in the Plan. 11

If the Administrator receives a request to withdraw shares on which dividends are not reinvested, between the record date and the dividend payment date, the withdrawal will be made within five days after receipt of the request and dividends will be paid to the Participant holding the shares prior to the withdrawal, in the usual manner, on the dividend payment date. If the Administrator receives a request to withdraw shares on which all or a portion of the dividends is reinvested, between the record date and the dividend payment date, 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 acquired 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. 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 an executed 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." Shares transferred within the Plan will continue to be held by the Administrator under 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 Investor's Choice. 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, 12

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 account would be reinvested through the Plan. Individual Retirement Account Investor's Choice offers Participants and interested investors an opportunity to establish a self-directed IRA which specifically allows for the reinvestment of cash dividends paid on Common Stock. The Investor's Choice IRA is offered only to Participants and investors who reside in the United States or its possessions or territories. In order to purchase shares through an IRA under the Plan, a Participant must execute an IRA Application Form and send it, together with an initial contribution, to the IRA Trustee. A minimum $1,000 initial purchase of Common Stock or a rollover or transfer of Common Stock from another IRA or qualified business retirement plan is required. The IRA Trustee will invest cash contributions of the IRA, when instructed, into shares of Common Stock under the Plan; however, the investment of IRA funds will not count against a Participant's $120,000 maximum annual Plan investment limit. In addition to the minimum enrollment and other Investor's Choice requirements, the IRA must comply with the IRA Trust Agreement and regulations governing IRAs under federal tax laws. Self-Direction. Each IRA Participant is allowed to make investment decisions with respect to the type and amount of investment in an IRA account. An IRA Participant may invest in Common Stock only or in Common Stock and other securities and assets, such as common stock of other corporations, mutual funds or other Value Plus IRA-eligible (or administratively feasible) assets. However, in order to participate through Investor's Choice, an IRA Participant must either maintain a portion of IRA assets in Common Stock and reinvest 100% of cash dividends on such stock into additional shares of Common Stock or make annual cash contributions for the purchase of Common Stock. Trustee. Each IRA account is required by law to have a trustee. The Company has selected First Trust Corporation in Denver, Colorado to act as the IRA Trustee for IRAs investing in Investor's Choice. First Trust is the largest independent trust company for self-directed IRAs in the U.S. It allows dividend reinvestment plans as "administratively feasible" investments for "self-directed" Value Plus Individual Retirement Accounts. First Trust Corporation and the Company are not affiliated or agents of one another, but have entered into a working relationship solely to assist investors that desire to use Investor's Choice in conjunction with a self-directed IRA. With respect to IRAs established under the Plan, the IRA Trustee, rather than the investors establishing the IRAs (the "IRA Participants"), will be the Investor's Choice Participant. Accordingly, all communications with the Company regarding the IRAs will be conducted by the IRA Trustee, who will receive the statements of accounts and other written confirmations from the Administrator and will send instructions, such as sale, transfer and withdrawal requests, to the Administrator on behalf of the IRAs. As described below, the IRA Trustee will, in turn, be responsible for maintaining all records and providing reports to each IRA Participant. Administration and Consolidated Reporting. The IRA Trustee maintains all IRA-related investment records, provides quarterly reports to each IRA Participant consolidating all IRA assets and activities, including Common Stock, into one convenient report and prepares and files any necessary Internal Revenue Service reporting. The IRA Trustee maintains a full-time customer service staff to answer IRA-related questions and accept investment 13

instructions from IRA Participants. As IRA Trustee for self-directed Investor's Choice IRAs, First Trust does not comment on the investment merits of any IRA asset. Costs. The Company charges no fees to establish an IRA under Investor's Choice. However, the IRA Trustee may charge fees for its plan maintenance and administration. First Trust does not charge to establish a Value Plus IRA but does charge $29 as an annual fee for maintenance of IRA accounts with balances under $10,000. There is no annual maintenance fee for Value Plus customers with account balances over $10,000. First Trust also does not charge transaction fees for reinvesting dividends on Common Stock held in the IRA account. The relationship between the IRA Participant and the IRA Trustee will be governed by standing instructions and other agreements between the IRA Participant and the IRA Trustee and will not be the responsibility of the Plan, the Administrator or the Company. Neither the Plan, the Administrator nor the Company will be liable for any of the IRA Trustee's acts or omissions relating to an IRA Participant's account. Reports to Participants Each Investor's Choice Participant will receive 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. Each Participant will receive copies of all communications sent to holders of Common Stock, including the Company's annual report to shareholders, notice of the annual meeting, proxy statement and form of proxy, as well as federal tax reporting statements, if applicable, for reporting taxable income received from the Company. All payments, notices, statements and reports will be sent to the Participant's address on the Administrator's records; therefore, it is imperative that Participants promptly notify the Administrator of any change of address. Certificates for Shares Shares of Common Stock purchased under, or deposited for safekeeping into, the Plan and credited to Participants' accounts will be held in an automated electronic record keeping system by the Administrator in its 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. Participants may obtain a certificate for all or part of the whole shares held in their accounts 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 receipt of the request by the Administrator. Any remaining whole or fractional shares will continue to be held in the Participant's account by the Administrator. Shares held in a Participant's account cannot be pledged or assigned. A Participant who wishes to pledge or assign any such 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. 14

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 (i) a certificate for all of the whole shares credited to the Participant's account, (ii) any dividends, interest payments and cash investments credited to the Participant's account and (iii) a check for the cash value of any fraction of a share of Common Stock credited to the Participant's account. Such fraction of a share shall 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 The Company 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. Such costs will be included as adjustments to the purchase and sale prices. As of the date of this Prospectus, the purchases of shares are occurring on the open market, and the brokerage fees and commissions and related service charges are not expected to exceed ten cents per share. There will be no brokerage fees and commissions or related services charges for shares of Common Stock purchased directly from the Company. Federal Income Tax Consequences THE FOLLOWING IS A SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATING IN INVESTOR'S CHOICE. TAX CONSEQUENCES WILL VARY AMONG PARTICIPANTS DEPENDING UPON INDIVIDUAL CIRCUMSTANCES AND STATE, LOCAL AND FOREIGN LAWS; THEREFORE, EACH PARTICIPANT SHOULD CONSULT A TAX ADVISOR AS TO THE TAX CONSEQUENCES 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 such dividends and interest payments were received by the Participant in cash. A Participant's cost basis for shares of Common Stock acquired under the Plan, in general, will be equal to the cash value of dividends and interest payments attributable to the purchase of the shares (adjusted for brokerage commissions and fees, services charges and applicable taxes, if any). A Participant's cost 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. Shares of Common Stock purchased under the Plan will have a holding period beginning on the day after the shares are allocated to the Participant's account. A Participant will not realize any taxable income as a result of receiving certificates for whole shares credited to an account under the Plan. Gain or loss will be recognized by the Participant as a result of the sale of such whole shares and upon the sale of any fractional shares credited to the Participant's account under the Plan. Under Internal Revenue Service backup withholding regulations, dividends and interest payments to be 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 15

(in the case of individual taxpayers the taxpayer identification number is the Participant's Social Security number). Any amount so withheld will not be reinvested under the Plan. The withheld amount 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 Company 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 the 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 shareholders. Fractions of shares cannot be voted. The Administrator will forward all shareholder materials relating to shares credited to a Participant's account to the Participant. Limitation of Liability None of the Company, the Administrator or 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. Interpretation and Regulation of Investor's Choice The officers of the Company are authorized to take such actions to carry out Investor's Choice as may be consistent with the Plan's terms and conditions. The Company reserves the right to interpret and regulate the Plan as the Company deems desirable or necessary in connection with the Plan's operations. Change or Termination of the Plan The Company may suspend, modify or terminate Investor's Choice at any time, in whole, in part or in respect of Participants in one or more jurisdictions, without the approval of Participants. Notice of such suspension, modification or termination will be sent to all affected Participants. Upon any whole or partial termination of Investor's Choice by the Company, each affected Participant will receive (i) a certificate for all of the whole shares credited to the Participant's account, (ii) any dividends, interest payments and cash investments credited to the Participant's account and (iii) a check for the cash value of any fraction of a share of Common Stock credited to the Participant's account. Such fraction of a share shall 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. 16

Termination of Participation by the Company 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, the Participant's participation in the Plan may be terminated by the Company upon written notice. Additionally, the Company 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 (i) a certificate for all of the whole shares credited to the Participant's account, (ii) any dividends, interest payments and cash investments credited to the Participant's account and (iii) a check for the cash value of any fraction of a share of Common Stock credited to the Participant's account. Such fraction of a share shall 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. PLAN OF DISTRIBUTION The Common Stock being offered hereby is offered pursuant to the Plan, the terms of which provide for the purchase of shares of Common Stock, either newly issued shares or shares held in the treasury of the Company, directly from the Company, or, at the Company's 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 in the open market by an Independent Agent. The Plan provides that the Company may not change its determination regarding the source of purchases of shares more than once in any three-month period. The primary consideration in determining the source of shares to be used for purchases under the Plan is expected to be the Company's need to increase equity capital. If the Company does not need to raise funds externally or if financing needs are satisfied using non-equity sources of funds to maintain the Company's 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. The Company will pay all administrative costs and expenses associated with Investor's Choice. 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. Such costs will be included as adjustments to purchase and sales prices. As of the date of this Prospectus, such brokerage fees and commissions and related service charges are not expected to exceed ten cents per share. There will be no brokerage fees and commissions or related service charges for shares of Common Stock purchased directly from the Company. DESCRIPTION OF CAPITAL STOCK The authorized capital stock of the Company consists of 700,000,000 shares of Common Stock, 10,000,000 shares of Preferred Stock, without par value, and 10,000,000 shares of Preference Stock, without par value ("Preference Stock"), of which 700,000 shares have been designated by the Board of Directors of the Company as Series A Preference Stock ("Series A Preference Stock"), 27,000 shares have been designated by the Board of Directors of the Company as Series B Preference Stock ("Series B Preference Stock") and 1,575 shares have been designated by the Board of Directors of the Company as Series C Preference Stock ("Series C Preference Stock"). Each share of Common Stock offered hereby includes an associated preference stock purchase right (a "Right"). The shares of Series A Preference Stock have been initially reserved for issuance upon exercise of the Rights. The descriptions of each of the Common Stock and the Rights are incorporated by reference into this 17

Prospectus. See "Incorporation of Certain Documents by Reference" for information on how to obtain a copy of these descriptions.
