ABOUT THIS PROSPECTUS As used in this prospectus and any prospectus supplement, except as the context otherwise requires, "we," "us," "our," "Company," and "KeySpan" mean KeySpan Corporation. This prospectus supersedes the Investor Program prospectus and prospectus supplements which were filed with the Securities and Exchange Commission on May 27, 1998, August 12, 1999 and December 6, 1999. Approximately 2.7 million shares have been issued under the Investor Program from May 27, 1999 through December 31, 2000. PROFILE OF KEYSPAN CORPORATION KeySpan Corporation, a New York corporation, was formed in May 1998, as a result of the business combination of KeySpan Energy Corporation, the parent of The Brooklyn Union Gas Company, and certain businesses of the Long Island Lighting Company. On November 8, 2000, we acquired Eastern Enterprises, a Massachusetts business trust, and the parent of several gas utilities operating in Massachusetts. Also on November 8, 2000, Eastern acquired EnergyNorth, Inc., the parent of a gas utility operating in central New Hampshire. As a result of the acquisitions, we now haves assets of more than $10 billion and have increased our customer base by approximately 800,000 New England customers, for a total of 2.4 million gas customers throughout the Northeast. Our core business is gas distribution, conducted by our six regulated gas utility subsidiaries: The Brooklyn Union Gas Company d/b/a KeySpan Energy Delivery New York and KeySpan Gas East Corporation d/b/a KeySpan Energy Delivery Long Island distribute gas to customers in the Boroughs of Brooklyn, Queens and Staten Island in New York City and the Counties of Nassau and Suffolk on Long Island, respectively; Boston Gas Company, Colonial Gas Company and Essex Gas Company, each doing business as KeySpan Energy Delivery New England, distribute gas to customers in eastern and central Massachusetts; and EnergyNorth Natural Gas, Inc. d/b/a KeySpan Energy Delivery New England distributes gas to customers in central New Hampshire. throughout the Northeast. We are also a major, and growing, generator of electricity. We own and operate five large generating plants and 42 smaller facilities in Nassau and Suffolk Counties on Long Island and lease and operate a major facility in Queens County in New York City. Under contractual arrangements, we provide power, electric transmission and distribution services, billing and other customer services for approximately one million electric customers of the Long Island Power Authority on Long Island. Our other subsidiaries are involved in oil and gas exploration and production; gas storage; wholesale and retail gas and electric marketing; appliance service; heating, ventilation and air conditioning installation and services; large energy-system ownership, installation and management; telecommunications; energy-related internet activities; fuel cells; water barging activities, including the hauling of fuel and other cargo; transportation by truck of liquid natural gas and propane; and providing meter reading equipment and services to municipal utilities. We also invest in, and participate in the development of, pipelines and other energy-related projects, domestically and internationally. 1 We are a registered holding company under the Public Utility Holding Company Act of 1935, as amended. Therefore, our corporate and financial activities and those of our subsidiaries (including their ability to pay dividends to us) are subject to regulation by the Securities and Exchange Commission. Under our holding company structure, we have no independent operations or source of income of our own and conduct substantially all of our operations through our subsidiaries and, as a result, we depend on the earnings and cash flow of, and dividends or distributions from, our subsidiaries to provide the funds necessary to meet our debt and contractual obligations. Furthermore, a substantial portion of our consolidated assets, earnings and cash flow is derived from the operations of our regulated utility subsidiaries, whose legal authority to pay dividends or make other distributions to us is subject to regulation by state regulatory authorities. 2 INVESTOR PROGRAM HIGHLIGHTS We are pleased to offer you the opportunity to participate in the KeySpan Investor Program (the "Program"), a direct stock purchase and dividend reinvestment plan. The Program is designed to provide you with: o A convenient and inexpensive way to purchase and sell shares of KeySpan common stock ("Common Stock"). o The chance to purchase additional shares of Common Stock, and to reinvest all or a portion of your cash dividends. o The opportunity to make additional cash purchases of Common Stock by check, money order or automatic deduction from your checking or savings account at a U.S. bank or financial institution. o An option to own and transfer shares of Common Stock without the need for holding stock certificates. PROGRAM ADMINISTRATION We have appointed EquiServe Trust Company N.A., ("EquiServe") as our trust agent to administer the Program.

Our Common Stock is listed on the New York Stock Exchange under the symbol KSE. Investing in KeySpan's Common Stock involves risks associated with market fluctuations. To the extent required by law, in certain jurisdictions, shares offered through the Program will be offered through a registered broker/dealer to persons who are not currently KeySpan shareholders. 3 DESCRIPTION OF THE PROGRAM SUMMARY This summary highlights selected information from this prospectus, but may not contain all of the information that is important to you.

New investors may make their initial investment in Common Stock by completing an Initial Investment Form and either mailing it with a check or money order for at least $250, or, alternatively, you can authorize EquiServe to automatically deduct your initial investment from a checking or savings account at a U.S. bank or financial institution. The automatic deduction feature also provides new investors with the option of having a minimum of $25 deducted either monthly or semi-monthly, in order to reach the minumum investment of $250. However, it will be necessary to notify Equiserve to stop making automatic deductions. o New investors can also enroll on the Internet at Equiserve's website at www.equiserve.com or the investor relations section of KeySpan's website at www.keyspanenergy.com. o New investors can reinvest their dividends by checking the dividend reinvestment option on the Initial Investment Form, or by calling EquiServe. REGISTERED SHAREHOLDERS o If you are a Registered Shareholder, you may make additional investments (minimum of $25, annual maximum of $150,000) by check, money order or by authorizing EquiServe to automatically deduct your investment from a checking or savings account at a U.S. bank or financial institution. o Registered Shareholders wishing to change dividend reinvestment options may do so by completing and submitting an Enrollment Authorization Form. 4 NON-REGISTERED SHAREHOLDERS o KeySpan shareholders holding their stock through a broker must become Registered Shareholders to enroll in the Program. FOR FURTHER INSTRUCTIONS ON HOW TO PARTICIPATE IN THE PROGRAM, PLEASE SEE QUESTION 7 BELOW.

PURPOSE 1. What is the purpose of the Program?

What are the Disadvantages of the Program? The disadvantages of the Program are as follows: o NO INTEREST PAID ON FUNDS PENDING INVESTMENT: No interest is paid on dividends or optional cash investments held by EquiServe pending investment or reinvestment. o PURCHASE/SALE PRICE DETERMINATION: Participants have no control over the share price or the timing of the sale or purchase of Program shares.

How do I become a Program participant? O NEW INVESTORS. If you do not currently own our Common Stock you may enroll in the Program by completing an Initial Investment Form. You must return the completed form to EquiServe with an initial investment of at least $250, but not more than $150,000. The payment can be in the form of a check or money order, made payable to "EquiServe - KeySpan." PLEASE DO NOT SEND CASH. You may also authorize automatic deductions of $25 per transaction from a checking or savings account at a U.S. bank or financial institution either monthly or semi-monthly, in order to reach the minimum investment of $250. Automatic deductions will continue until such time as the new investor notifies EquiServe in writing to stop making automatic deductions. An Automatic Deduction Authorization Form is included on the reverse side of the Initial Investment Form. o IF YOU ARE A REGISTERED SHAREHOLDER. If you own shares of Common Stock that are registered in your name, not the name of a broker, you can enroll in the Program by completing and returning an Enrollment Authorization Form to EquiServe or by calling EquiServe directly at 1-800-482-3638. You may obtain additional Enrollment Authorization Forms at any time upon request to EquiServe. o IF YOU ARE A NON-REGISTERED SHAREHOLDER If you are the beneficial owner of Common Stock through a bank, broker, or trustee, you can become a Registered Shareholder by instructing your bank, broker, or trustee to transfer some or all of your shares of Common Stock into your name. You can choose whether to receive a physical stock certificate for your shares of Common Stock, have them registered in the Direct registration System in your name or deposit them in a book-entry Program account maintained by EquiServe. 8 o STOCK CERTIFICATE. Once you receive your stock certificate in your name, you can enroll in the Program and you may begin to use all of the services of the Program, such as the dividend reinvestment and economical selling of shares features. o DIRECT REGISTRATION SYSTEM BOOK-ENTRY SHARES. This is an electronic transfer of your shares from your broker's name into your name through the Direct Registration System. Simply instruct your broker to conduct the transaction and begin to use any or all of the Program services. o DEPOSIT SHARES WITH EQUISERVE IN BOOK-ENTRY ACCOUNT. You can also opt to have your shares held in a book-entry account administered by EquiServe. This allows you to have the added safe-keeping feature which protects you against the loss, theft or destruction of stock certificate loss. You may also arrange to have your bank, broker, or nominee participate in the Program on your behalf. In this case, your participation may be on terms and conditions which differ from the terms and conditions set forth in this Program, you will be limited to the dividend reinvestment feature use of the Program only. The terms and conditions set forth in the Program will also be subject to the terms and conditions of your bank, broker, or nominee. EquiServe will not have a record of your transactions or your account since they will remain under the name of your bank or broker. 8. What are my dividend reinvestment options available under the Program? The following options are available to you under the Program. However, you must elect one of the following options on the Initial Investment Form or the Enrollment Authorization Form in order to have any portion of your dividends paid to you, otherwise they will automatically be fully reinvested to purchase additional shares of Common Stock. o FULL DIVIDEND REINVESTMENT. You can opt to have all of your cash dividends on all certificated and Program shares of Common Stock automatically reinvested to purchase additional shares of Common Stock. If you do not make an election on the Initial Enrollment Form or the Enrollment Authorization Form you will automatically have your dividends fully reinvested. o PARTIAL DIVIDEND REINVESTMENT. You may choose to receive your cash dividends on a specified number of shares of Common Stock and automatically have the cash dividends on the remainder of your shares of Common Stock reinvested to purchase additional shares of Common Stock. If you elect to have partial dividends reinvestment, you must designate the number of Program shares and/or certificated shares for which you choose to receive your cash dividends in a whole number. Cash dividends are sent to you by check or, upon request, are deposited electronically into your U.S. bank account. o FULL CASH PAYMENT. You may choose to receive all of your dividends as a cash payment. Cash dividends are sent to you by check or, upon request, are deposited electronically into your U.S. bank account. FOR MORE INFORMATION ON THE ELECTRONIC DEPOSIT OF DIVIDENDS, PLEASE REFER TO QUESTION 10, OR CONTACT EQUISERVE. 9 9. How do I make additional cash investments in Common Stock? You may make additional cash investments by choosing among the following two options: o CHECK INVESTMENT. You may make additional cash investments in Common Stock by sending to EquiServe a check, money order, or bank draft for the purchase of additional shares of Common Stock. The check, money order, or bank draft must be made payable to "EquiServe - KeySpan" in U.S. dollars and drawn on a U.S. bank. If you are not in the U.S., contact your bank to verify that they can provide you with a check that clears through a U.S. bank and can print the dollar amount in U.S. funds. Due to the longer clearance period, we are unable to accept checks clearing through non-U.S. funds. EquiServe will not accept third party checks. All checks, money orders, and bank drafts should be sent to EquiServe at the address listed on the tear-off form attached to each Program account statement you receive, or with your Initial Enrollment Form or Enrollment Authorization Form. o AUTOMATIC INVESTMENT FROM A BANK ACCOUNT. As an alternative to sending checks, money orders, and bank drafts for additional cash investments, you may elect to have funds automatically withdrawn from your checking or savings account at a U.S. bank or financial institution. You may elect the automatic deduction option by completing and signing an Automatic Deductions Authorization Form and returning this form to EquiServe, together with a voided blank check or savings account deposit slip for the bank account from which the funds are to be withdrawn. Additional Automatic Deductions Authorization Forms are available through EquiServe. Your Automatic Deductions Authorization Form will be processed and will become effective as promptly as practicable. However, you should allow four to six weeks for the first investment to be initiated using this automatic deduction feature. Once automatic deductions begin, funds will be withdrawn from your bank account on either the first or fifteenth day of each month, or both (at your option), or on the next business day if either of those days is not a business day. You may change or discontinue automatic deductions by completing and submitting to EquiServe a new Automatic Deductions Authorization Form. Brokers or bank nominees participating on behalf of Non-Registered Shareholders or beneficial owners may only use the dividend reinvestment feature of the Program and cannot use the additional cash investment feature. If a Non-Registered Shareholder wishes to participate in the additional cash investment feature of the Program, he or she must first become a Registered Shareholder or make an initial investment to enroll directly in the Program. 10. Can my cash dividends be deposited directly to my bank account? Yes, you may elect to have any cash dividends which are not reinvested paid by electronic funds transfer to your U.S. bank account. To do this, you must first complete and return a Direct Deposit Authorization Form to EquiServe along with a copy of a voided blank check or savings account deposit slip. This form is not included with your Program materials and must be specifically requested from EquiServe or obtained online at www.equiserve.com. 11. What are the minimum and maximum amounts for additional cash investments? In addition to increasing your holdings of Common Stock through the reinvestment of dividends, you may make additional cash investments in Common Stock at any time. Your additional cash 10 investments by check, money order, or automatic deductions must be at least $25 with a maximum allowable investment of $150,000 per calendar year. If you are not a Registered Shareholder and are a first time investor in the Program, your initial investment must be for at least $250 and cannot exceed $150,000. SEE QUESTION 7 REGARDING NEW INVESTORS. COMMON STOCK PURCHASES 12. What are the sources of Common Stock purchased under the Program? Shares of Common Stock will be purchased either on the open market, or directly from KeySpan, from shares held in our treasury or as newly issued shares, or a combination of the foregoing. You cannot choose the source of your shares purchased since this is entirely at our discretion. Shares purchased on the open market may be made on any stock exchange where our Common Stock is traded or by negotiated transactions on terms that EquiServe may reasonably determine. Neither KeySpan nor any participant will have any authority or power to direct the date, time, or price at which shares of Common Stock may be purchased, or the selection of a broker or dealer through or from whom purchases are made. 13. When will shares be purchased under the Program? o GENERAL. Direct purchases from KeySpan's authorized but unissued shares of Common Stock will normally be made on a weekly basis on the relevant "investment date," (usually Thursdays) or the next trading day if the investment date is not a trading day. Purchases on the open market will begin on the investment date and will be completed no later than 30 days from such date, except where completion at a later date is necessary or advisable under any applicable federal securities law. o CASH INVESTMENTS. EquiServe will normally invest any initial and additional cash investments for the purchase of Common Stock on a weekly basis, usually on Thursdays, after receipt of the check, money order, bank draft or automatic deduction. EquiServe will determine the actual investment date for initial and additional cash investments. o DIVIDEND REINVESTMENTS. The investment date for dividend reinvestments will be the dividend payment date or the next business day if the dividend payment date is not a business day. If EquiServe receives your Enrollment Authorization Form requesting reinvestment of dividends on or before the record date established for a particular dividend, reinvestment will commence with that dividend. If EquiServe receives your Enrollment Authorization Form requesting reinvestment of dividends after the record date established for a particular dividend, you will be paid the dividend in cash and your reinvestment of dividends will begin on the next dividend payment date. The anticipated payment dates for Common Stock are usually on the first business day of February, May, August, and November. The record dates for Common Stock are usually the week of the 10th of the previous month of the payment date. It is anticipated that record dates and payment dates for dividends, that we may declare in the future, will be at approximately the same times of the year. 11 14. How is the purchase price of the Common Stock determined? The purchase price of Common Stock purchased directly from KeySpan, as treasury shares or original issue shares, will be the average of the high and low prices of the Common Stock as reported in the New York Stock Exchange composite transactions for that investment date. The purchase price of Common Stock purchased on the open market is the weighted average of the actual purchase price of all shares purchased during the applicable investment period. The price is adjusted to include brokerage commissions of $0.05 per share. Open market purchases are expected to be made through EquiServe. A Program participant will have the applicable commissions deducted from the funds used to purchase shares acquired under the Program, SEE QUESTION 25. 15. How many shares of Common Stock will be purchased for me? The number of shares purchased for you will be equal to the amount of your additional cash investments, plus any dividends available for reinvestment, or the initial investment received by EquiServe during the investment period, less any applicable fees, divided by the purchase price of the shares. Your Program account will be credited with the number of shares of Common Stock, including fractional shares computed to three decimal places.. 16. Will I be paid interest on any amounts pending the actual investment date? No. Interest will not be paid on amounts sent to EquiServe for investment pending the actual investment date. STOCK CERTIFICATES AND SAFE KEEPING 17. Will I be issued stock certificates for shares of Common Stock purchased through the Program? No. Shares of Common Stock purchased through the Program will not be issued to you in stock certificate form, but will be credited to your Program account - as book entry shares - by EquiServe on your behalf. The number of shares of Common Stock credited to your Program account will be shown on your Program account statement. 18. How may I receive a stock certificate? You may obtain a stock certificate at no cost for some or all of the whole shares credited to your Program account at any time by simply requesting EquiServe to withdraw shares from your Program account and to issue them in stock certificate form. You may make such a request by: o Calling EquiServe at 1-800-482-3638; o Accessing your Program account through the Internet at EquiServe's website www.equiserve.com; ----------------- o Using the tear-off form attached to the Program account statement; or o Sending written notice specifying the number of whole shares to be withdrawn. 12 Stock certificates will be issued to you and registered in your name. Stock certificates are normally issued to participants within two business days after receipt of a request. No stock certificates will be issued for a fractional share of Common Stock. If you request a stock certificate for all shares credited to your Program account, a stock certificate will be issued for the whole shares and a cash payment will be made for any remaining fractional shares. That cash payment will be based upon the then-current market price of the Common Stock, less any service fee, any applicable brokerage commission, and any other costs of sale. Withdrawing shares from your Program account into stock certificate form does not affect your dividend reinvestment option. For example, if you authorized the full dividend reinvestment option, cash dividends with respect to shares withdrawn from you Program account in stock certificate form will continue to be reinvested. 19. May I add my shares of Common Stock held in stock certificate form to my Program account with EquiServe for safekeeping purposes? Yes, you may deposit any Common Stock certificate in your possession and registered in your name with EquiServe for credit to your Program account as book-entry shares at any time, at no cost. We will pay all fees for this service. This safekeeping feature offers two advantages: o The risk associated with loss, theft, or destruction of stock certificates is eliminated; otherwise, in the case of a lost or stolen stock certificate, no sale or transfer may occur until a replacement is obtained, which can be a costly and time-consuming process; and o Since shares deposited into your Program account with EquiServe are treated in the same manner as shares purchased through the Program, they may be transferred or sold through the Program in a convenient and efficient manner. To combine shares held in stock certificate form with shares credited to your Program account, you must send your request and your stock certificates to EquiServe. The stock certificates should not be endorsed. EquiServe will promptly send you a statement confirming each stock certificate deposited. To insure against loss resulting from mailing stock certificates to EquiServe, the Program provides for mail insurance, free of charge, for stock certificates valued up to $25,000 current market value (maximum coverage) when mailed first class, using a brown, pre-addressed envelope provided by EquiServe. Envelopes may be obtained by calling EquiServe at 1-800-482-3638. For information about mailing stock certificates which have a current market value in excess of $25,000, you should contact EquiServe. To be eligible for stock certificate mailing insurance, you must notify EquiServe of any lost stock certificate claim within 30 calendar days of the date the stock certificates were mailed. Mail insurance covers the replacement of shares of Common Stock, but in no way protects you against any loss resulting from fluctuations in the value of the shares from the time you mail the stock certificates until the time replacement can be made. If you do not use a brown, pre-addressed envelope provided by EquiServe, you should send your stock certificates to the address listed in Question 5 by registered mail, return receipt requested, and insure for possible mail loss for 2% (minimum of $20) of the market value. This represents the approximate cost to you of replacing stock certificates if they are lost or stolen. 13 SALE OF SHARES 20. How can I sell Program shares? To sell any shares that you hold in stock certificate form through the Program, the shares must first be converted into book-entry shares and credited to your Program account with EquiServe. You can sell any of the shares credited to your Program account with EquiServe by calling EquiServe at 1-800- 482-3638, accessing your Program account via the Internet at www.equiserve.com, by writing to EquiServe, or by completing and submitting the tear-off portion of your Program account statement. 21. How is the sale price of Program shares determined? EquiServe aggregates all requests to sell shares and then sells the total share amount on the open market. Upon receipt of your request to sell some or all of your shares, EquiServe will make every reasonable effort to process all sales orders on the day the orders are received. To do so, you must ensure that instructions are received before 1:00 p.m. (Eastern Time) on a business day during which EquiServe and the New York Stock Exchange are open. Sales will be made at the then-current market price of the Common Stock and EquiServe will promptly mail you a check. The check will be for the net cash proceeds of the sale, minus a service fee of $5.00 plus brokerage commissions of $0.05 per share. EquiServe has full discretion in all matters related to the sale, including the time of sale and sales price and the selection of a broker. You cannot specify a price or a time at which to sell your book-entry shares. You should be aware that the Common Stock price may rise or fall during the period between a request for sale, its receipt by EquiServe and the ultimate sale on the open market. Instructions sent to EquiServe to sell shares are irrevocable and may not be rescinded. TRANSFER OF SHARES 22. Can I assign or transfer all or a part of my Program shares to another person? Yes. You may change ownership of all or part of your Program shares through a gift, sale or otherwise at any time. You may contact EquiServe at 1-800-482-3638 for complete transfer instructions and you will be asked to send EquiServe written transfer instructions to enact the transfer. Requests for transfer are subject to the same requirements as for the transfer of stock certificates, including the requirement of a Medallion Signature Guarantee. 23. If Program shares are transferred to another person, will EquiServe issue a stock certificate to the transferee? No. Transfers will be credited to an account in book entry form. If you so request, a stock certificate can be issued to the transferee. You should contact the EquiServe for full details on how to make the transfer. For book entry transfers that involve the establishment of a new Program account, a new Initial 14 Investment Form, or written instructions, must be completed by the transferee. The completed Initial Investment Form must be returned to EquiServe, along with written instructions signed by the current participant, indicating the number of shares to be transferred to the transferee. The current participant's signature must be guaranteed by a bank, broker or financial institution that is a member of the Medallion Signature Guarantee program. The new Program account will be set up for full dividend reinvestment unless otherwise instructed by the previous or new shareholder. OPTION CHANGES AND DISCONTINUATION OF REINVESTMENT 24. How can I change my dividend reinvestment option or discontinue reinvesting my dividends? You may change dividend reinvestment options by calling EquiServe directly at 1-800-482-3638, instructing EquiServe in writing, through the Internet or by submitting to EquiServe a new election on an Enrollment Authorization Form. To be effective for a specific dividend, any change must be received by EquiServe before the record date for that dividend - see Question 13 for information regarding record dates. You may discontinue reinvestment of cash dividends at any time by calling or writing EquiServe or through the Internet. If EquiServe receives your request to discontinue dividend reinvestment on or after the record date for a dividend, EquiServe may either pay the dividend in cash or reinvest it under the Program on the next investment date on your behalf. If reinvested, EquiServe may sell the shares purchased and send the proceeds to you, less any service fees applicable, brokerage commissions and other costs of sale. After processing your request to discontinue dividend reinvestment, any dividends on any shares credited in book-entry form or shares you hold in stock certificate form will be paid in cash by check or by electronic funds transfer. To have dividends deposited directly to your U.S bank account, see Question 10. 25. Are there any fees charged to me as a Program participant? Below is a tabular summary of Program fees as they may relate to you. Transaction Fees/Commissions - ------------------------------------------------------------------------------- Initial Enrollment Fee None - ------------------------------------------------------------------------------- Additional Investment Purchase (by check, money order or automatic deductions) - Original Issue None - Treasury None - Open Market $0.05 per share - ------------------------------------------------------------------------------- Reinvestment of Dividends Fee - Original Issue None - Treasury None - Open Market $0.05 per share - ------------------------------------------------------------------------------- Selling Program shares $5.00 + $0.05 per share - ------------------------------------------------------------------------------- 15 - ------------------------------------------------------------------------------- Issuance of Certificates None - ------------------------------------------------------------------------------- Deposit of Certificates None - ------------------------------------------------------------------------------- Transfers of Shares None - ------------------------------------------------------------------------------- Returned checks or failed $20.00 automatic deductions - ------------------------------------------------------------------------------- Duplicate statements $5 per year (2 years or older). (not to exceed $25.00) - ------------------------------------------------------------------------------- REPORTS TO PARTICIPANTS 26. What kind of reports will I be sent? To assist you in your record keeping, EquiServe will send you the following information: - For each initial cash investment, additional cash purchase, sale or transfer that you make or receive, a statement detailing the transaction; - For each dividend reinvested, a statement detailing all activity in your Program account for that quarter; - For any transactions you make after the fourth quarter dividend, an updated cumulative statement detailing all activity in your Program account for that year; - You will also be sent copies of the communications sent to other shareholders. These include KeySpan's annual reports, notices of annual meeting and proxy statements, company updates, and income tax information for reporting dividends paid and proceeds from the sale of Program shares. However, if you are a beneficial owner who participates through a broker or bank nominee, you should contact your broker or bank nominee for a statement detailing reinvestment activity. FEDERAL INCOME TAXES 27. What are some of the tax consequences of participation in the Program? In general, dividends that are reinvested in accordance with the Program will be taxed as cash dividends for federal income tax purposes under the provisions of the applicable tax laws. If you sell shares of Common Stock under the Program, this will give rise to capital gains or losses, provided you hold such shares as a capital asset. The amount of any such gain or loss will be the difference between the proceeds you receive (net of commissions and fees) and your tax basis. The tax basis of shares acquired through the Program is equal to the purchase price of such shares (including brokerage commissions and fees, if any). See the answer to Question 14 for how the purchase price is determined. 16 The foregoing is only a general discussion of certain federal income tax aspects of an investment in the Program. Because tax consequences may vary, depending on each participant's own tax situation, you are advised to consult your own tax advisors regarding the tax effect of participation in the Program, including the application of current and proposed federal, state, local, foreign and other tax laws. OTHER INFORMATION 28. What happens if KeySpan issues a stock dividend, declares a stock split or has a rights offering? All stock dividends or split shares distributed by us on shares credited to your Program account and/or on shares held by you in the form of stock certificates will be credited directly into your Program account. You will receive a statement indicating the number of shares or dividends earned as a result of the transactions. This includes entitlements on shares calculated on book-entry shares and certificated shares registered in your name. In the case of a rights offering, your rights will be based on the full shares credited to your Program account and/or on shares held by you in the form of stock certificates. 29. How will my shares be voted? For any meeting of Common Stock shareholders, all participants will receive proxy materials including a proxy card representing both the shares for which you hold stock certificates and the whole shares credited to your Program account. All shares will be voted as designated by you or may be voted in person at shareholder meetings. 30. What are the responsibilities of KeySpan and EquiServe under the Program? In administering the Program, KeySpan and EquiServe will not be liable for any of the following acts done in good faith: - Any claim of liability with respect to the shares of Common Stock of a deceased participant's Program account prior to receipt in writing of instructions relating to the disposition of such shares; - With respect to the prices at which shares of Common Stock are purchased or sold for the participant's Program account and the times when such purchases or sales are made; - With respect to any fluctuation in the market value before or after any purchase or sale of shares of Common Stock. Holding Common Stock under the Program is no different than holding shares on your own. Neither KeySpan nor EquiServe assure you of a profit or protect you from any losses sustained on the purchase of Common Stock under the Program. 31. May the Program be changed or discontinued? 17 We reserve the right to amend, suspend, discontinue or modify the Program at any time without the approval of participants. Notice of our determination to suspend, discontinue or modify the Program will be given to all Program participants as soon as practicable after such determination is made. Changes or discontinuation will not affect your rights as a shareholder in any way and any book-entry shares you own will continue to be credited to your Program account unless you specifically request otherwise. 32.

The Program also provides for the purchase of Common Stock on the open market by an agent independent of the Company. To the extent that shares of Common Stock are purchased directly from the Company, the net proceeds are expected to be used for general corporate purposes. The Company cannot estimate the number of shares of Common Stock that the Company will sell through the Program or the prices at which such shares will be sold. Should Program shares be purchased on the open market, the Company will not receive any of the proceeds from the sale of such shares. The Company does not expect to change the source of Program shares frequently and will not do so more than once in any three month period or such other period of time as may be permitted under future SEC regulations. PLAN OF DISTRIBUTION The shares of Common Stock will be offered directly to Program participants without underwriters as described in this prospectus.

Indemnification of Directors and Officers. The New York Business Corporation Law ("BCL"), Article 7, Sections 721-726 provide for the indemnification and advancement of expenses to officers and directors. Section 721 provides that indemnification and advancement pursuant to the BCL are not exclusive of any other rights an officer or director may be entitled to, provided that no indemnification may be made to or on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that the director personally gained a financial profit or other advantage to which he or she was not legally entitled. Section 722 of the BCL provides that a corporation may indemnify an officer or director, in the case of third party actions, against judgments, fines, amounts paid in settlement and reasonable expenses and, in the case of derivative actions, against amounts paid in settlement and reasonable expenses, provided that the director or officer acted in good faith, for a purpose which he or she reasonably believed to be in the best interests of the corporation and, in the case of criminal actions, had no reasonable cause to believe his conduct was unlawful. In addition, statutory indemnification may not be provided in derivative actions (i) which are settled or otherwise disposed of or (ii) in which the director or officer is adjudged liable to the corporation, unless and only to the extent a court determines that the person is fairly and reasonably entitled to indemnity. Section 723 of the BCL provides that statutory indemnification is mandatory where the director or officer has been successful, on the merits or otherwise, in the defense of a civil or criminal action or proceeding. Section 723 also provides that expenses of defending a civil or criminal action or proceeding may be advanced by the II-1 corporation upon receipt of an undertaking to repay them if and to the extent the recipient is ultimately found not to be entitled to indemnification. Section 725 provides for repayment of such expenses when the recipient is ultimately found not to be entitled to indemnification. Section 726 provides that a corporation may obtain indemnification insurance indemnifying itself and its directors and officers. The registrant has in effect insurance policies providing both directors and officers liability coverage and corporate reimbursement coverage. Section 402(b) of the BCL provides that a corporation may include in its certificate of incorporation a provision limiting or eliminating, with certain exceptions, the personal liability of directors to a corporation or its shareholders for damages for any breach of duty in such capacity. The certificate of incorporation of the registrant contains provisions eliminating the personal liability of directors to the extent permitted by New York law. The registrant's certificate of incorporation provides generally that it shall, except to the extent expressly prohibited by the BCL, indemnify each of its officers and directors made or threatened to be made a party to any action, suit or proceeding, or appeal thereof, whether civil or criminal by reason of the fact that such person is or was an officer or director against all expense, liability and loss (including, but not limited to all attorneys' fees, judgments, fines, pension plan taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith. The certificate of incorporation further provides for advancement and reimbursement of such expenses incurred by an officer or director in defending any action or proceeding in advance of the final disposition thereof upon receipt of an undertaking by such person to repay such amount if, and to the extent that, such person is ultimately found not to be entitled to indemnification. Item 16. List of Exhibits. See Exhibit Index Item 17. Undertakings. (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 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 II-2 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) 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) do not apply if the Registration Statement is on Form S-3, Form S-8, or Form F-3 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 Securities and Exchange Commission by the Issuer 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 Issuer'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 such registrant pursuant to the provisions referred to in Item 15 of this registration statement, 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 such Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by such registrants of expenses incurred or paid by a director, officer or controlling person of such registrants 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 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, KeySpan Corporation certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement amendment to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Brooklyn, State of New York, on the 12th day of December, 2000.
