CERTAIN PERSONS PARTICIPATING IN THIS OFFERING MAY ENGAGE IN TRANSACTIONS THAT STABILIZE, MAINTAIN OR OTHERWISE AFFECT THE PRICE OF THE OFFERED BONDS. SPECIFICALLY, THE UNDERWRITER MAY OVERALLOT IN CONNECTION WITH THIS OFFERING OR MAY BID FOR, AND PURCHASE, THE OFFERED BONDS IN THE OPEN MARKET. FOR A DESCRIPTION OF THESE ACTIVITIES, SEE "UNDERWRITING." _______________ CERTAIN TERMS OF THE OFFERED BONDS The following information concerning the Offered Bonds supplements and should be read in conjunction with the statements under "Description of New Bonds" in the accompanying Prospectus. Capitalized terms not defined herein are used as defined in the accompanying Prospectus. GENERAL. The $20,000,000 aggregate principal amount of Offered Bonds will be issued as a new series of the Company's First Mortgage Bonds under the Mortgage, as supplemented and amended by various supplemental indentures, including the Twentieth Supplemental Indenture dated as of November 1, 1997 relating to the Offered Bonds. INTEREST, MATURITY AND PAYMENT. The Offered Bonds will mature on November 15, 2007 and will bear interest from November 15, 1997 at the rate shown in their title, the first interest payment to be made on May 15, 1998, with subsequent payments to be made semi-annually on November 15 and May 15. Principal and interest are payable at The Bank of New York. REDEMPTION AND PURCHASE OF BONDS. The Offered Bonds are not redeemable prior to maturity. SINKING FUND OR IMPROVEMENT FUND. The Offered Bonds are not entitled to the benefit of a sinking or improvement fund or other provision for amortization prior to maturity. BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY. The Depository Trust Company ("DTC") will act as securities depository for all of the Offered Bonds. The Offered Bonds will be issued as fully-registered bonds registered in the name of Cede & Co., DTC's partnership nominee. One fully-registered global certificate, representing the aggregate principal amount of the Offered Bonds, will be issued and will be deposited with DTC. DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the 1934 Act. DTC holds securities that its participants ("Participants") deposit with DTC. DTC also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations ("Direct Participants"). DTC is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others, such as securities brokers and dealers, banks and trust companies that clear transactions through or maintain a direct or indirect custodial relationship with a Direct Participant ("Indirect Participants"). The rules applicable to DTC and its Participants are on file with the Commission. Purchases of the Offered Bonds within the DTC system must be made by or through Direct Participants, which will receive a credit for the Offered Bonds on DTC's records. The ownership interest of each actual purchaser of each Offered Bond (the "Beneficial Owner") is in turn to be recorded on the S-2 Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchases, but Beneficial Owners are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the Participants through which the Beneficial Owners purchased Offered Bonds. Transfers of ownership interests in the Offered Bonds are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Offered Bonds, except in the event that use of the book-entry system for Offered Bonds is discontinued. To facilitate subsequent transfers, all Offered Bonds deposited by Participants with DTC are registered in the name of Cede & Co. The deposit of Offered Bonds with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Offered Bonds; DTC's records reflect only the identity of the Direct Participants to whose accounts such Offered Bonds are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants and by Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements that may be in effect from time to time. Neither DTC nor Cede & Co. will consent or vote with respect to Offered Bonds. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the Offered Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy). Principal and interest payments on the Offered Bonds will be made to DTC. DTC's practice is to credit Direct Participants' accounts on the payable date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payment on the payable date. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in "street name," and will be the responsibility of such Participants and not of DTC, the Company or the Trustees, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal and interest to DTC is the responsibility of the Company and the paying agent, disbursement of such payments to Direct Participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of Participants. Except as provided herein, a Beneficial Owner will not be entitled to receive physical delivery of Offered Bonds. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the Offered Bonds. DTC may discontinue providing its services as securities depository with respect to the Offered Bonds at any time by giving reasonable notice to the Company. Under such circumstances, in the event that a successor securities depository is not obtained, bond certificates are required to be printed and delivered. The Company may decide to discontinue use of the system of book-entry transfers through DTC (or any successor depository). In that event, bond certificates will be printed and delivered. The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that the Company believes to be reliable, but the Company does not take responsibility for the accuracy thereof. S-3 APPLICATION OF PROCEEDS The net proceeds to be received from the sale of the Offered Bonds will be added to the Company's general funds and will be used for the redemption or retirement of outstanding indebtedness and for other general corporate purposes. Proceeds not immediately used for such purpose will be temporarily invested in short-term investments.

The Underwriting Agreement provides that the obligation of the Underwriter to pay for and accept delivery of the Offered Bonds is subject to the approval of certain legal matters by its counsel and to certain other conditions. In the Underwriting Agreement, the Underwriter has agreed, subject to the terms and conditions set forth therein, to purchase all the Offered Bonds offered hereby if any Offered Bonds are purchased. The Company has been advised by the Underwriter that it proposes initially to offer the Offered Bonds to the public at the public offering price set forth on the cover page of this Prospectus Supplement, and to certain dealers at such price less a concession not in excess of 0.40 of 1% of the principal amount of the Offered Bonds. The Underwriter may allow, and such dealers may reallow, a concession not in excess of 0.25 of 1% of the principal amount of the Offered Bonds to certain other dealers. After the initial public offering, the public offering price and such concessions may be changed. The Underwriting Agreement provides that the Company will indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933. Until the distribution of the Offered Bonds is completed, rules of the Commission may limit the ability of the Underwriter to bid for and purchase the Offered Bonds. As an exception to these rules, the Underwriter is permitted to engage in certain transactions that stabilize the price of the Offered Bonds. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Offered Bonds. In addition, if the Underwriter creates a short position in the Offered Bonds in connection with this offering of the Offered Bonds (i.e., they sell more Offered Bonds than are set forth on the cover page of this Prospectus Supplement), the Underwriter may reduce the short position by purchasing Offered Bonds in the open market. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. Neither the Company nor the Underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Offered Bonds. In addition, neither the Company nor the Underwriter makes any representation that the Underwriter will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

The New Bonds will be redeemable, in whole or in part, on 30 days notice at the redemption prices set forth in the Prospectus Supplement for redemptions including (i) for the basic improvement fund, (ii) for the maintenance and replacement fund, (iii) with certain deposited cash, (iv) with proceeds of released property, or (v) at the option of the Company. Reference is made to the Prospectus Supplement for the redemption terms of the Offered Bonds. If at the time notice of redemption is given the redemption moneys are not on deposit with the Corporate Trustee, the redemption may be made subject to their receipt before the date fixed for redemption. Cash deposited under any provisions of the Mortgage (with certain exceptions) may be applied to the purchase of Bonds of any series. (Mortgage, Art. X.) Sinking or Improvement Fund. Reference is made to the Prospectus Supplement concerning whether or not the Offered Bonds are entitled to the benefit of a sinking or improvement fund or other provision for amortization prior to maturity. Of the currently outstanding Bonds, only the 6-1/2% Series due January 1, 1998 has sinking fund or improvement fund provisions. Replacement Fund. Although the New Bonds as such are not entitled to the benefit of a replacement fund, so long as any Bonds of the 6- 1/2% Series due January 1, 1998 are outstanding, there shall be expended for each year for replacements and improvements in respect of the mortgaged electric, gas, steam and/or hot water utility property and of certain automotive equipment an amount equal to $750,000 plus 2 percent of net additions to such depreciable mortgaged property made after June 30, 1945 and prior to the beginning of such year. Such requirement may be met with cash or gross property additions or by certifying net cash expenditures for certain automotive equipment or by taking credit for Bonds and qualified lien bonds retired. Any excess in such credits may be applied against future requirements. Such cash may be withdrawn on gross property additions or on waiver of the right to issue Bonds or be applied to the purchase or redemption of Bonds of such series as may be designated by the Company, including the New Bonds. (Mortgage, Sec. 39; Fourth Supplemental, Sec. 3.) - 6 - Special Provisions for Retirement of Bonds. If, during any 12 month period, mortgaged property is disposed of by order of or to any governmental authority resulting in the receipt of $5 million or more as proceeds, the Company (subject to certain conditions) must apply such proceeds, less certain deductions, to the retirement of Bonds. (Mortgage, Sec. 64.) Reference is made to the Prospectus Supplement for information concerning whether the New Bonds are redeemable for this purpose and, if so, at what redemption prices. Security. The New Bonds and any other Bonds now or hereafter issued under the Mortgage will be secured by the Mortgage, which constitutes, in the opinion of General Counsel for the Company, a first lien on all of the electric generating plants and other materially important physical properties of the Company and substantially all other properties described in the Mortgage as owned by the Company, subject to (a) leases of minor portions of the Company's property to others for uses which, in the opinion of such counsel, do not interfere with the Company's business, (b) leases of certain property of the Company not used in its electric utility business, and (c) excepted encumbrances, minor defects and irregularities, but such counsel has not examined title to or passed upon title to reservoir lands, easements or rights of way, any property not costing in excess of $25,000, or lands or rights held for flowage, flooding or seepage purposes, or riparian rights. There are excepted from the lien: cash and securities; merchandise, equipment, materials or supplies held for sale or other disposition; aircraft, automobiles and other vehicles, and materials and supplies for repairing and replacing the same; timber, minerals, mineral rights and royalties; receivables, contracts, leases and operating agreements. The Mortgage contains provisions for subjecting after-acquired property (subject to pre-existing liens) to the lien thereof, subject to limitations in the case of consolidation, merger or sale of substantially all of the Company's assets. The Mortgage provides that the Trustees shall have a lien upon the mortgaged property, prior to the Bonds, for the payment of their reasonable compensation, expenses and disbursements and for indemnity against certain liabilities. (Mortgage, Sec. 96.) No stocks or properties of subsidiaries are subject to the Mortgage. Issuance of Additional Bonds. The maximum principal amount of Bonds which may be issued under the Mortgage is not limited. Bonds of any series may be issued from time to time on the basis of: (1) 60 percent of property additions after adjustments to offset retirements; (2) retirement of Bonds or qualified lien bonds; and (3) deposit of cash. With certain exceptions in the case of (2) above, the issuance of Bonds requires adjusted net earnings before income taxes for 12 out of the preceding 15 months of at least twice the annual interest requirements on all Bonds at the time outstanding, including the additional issue, and on all indebtedness of prior rank. Such adjusted net earnings are computed after provision for retirement and depreciation of property equal to the replacement fund requirements for such period. It is expected that the New Bonds will be issued upon the basis of the retirement of Bonds or property additions. Property additions generally include electric, gas, steam or hot water property acquired after June 30, 1945, but may not include securities, aircraft, automobiles or other vehicles, or property used principally for the production or gathering of natural gas. There was available, as of December 31, 1996, unfunded net property additions of approximately $111,272,239. In general, when the Bonds of the 6-1/2% Series due January 1, 1998 have been retired, property additions theretofore funded to satisfy sinking or improvement funds and/or replacement funds for all series will revert to unfunded status, and such property additions, as well as any Bonds theretofore used to satisfy all series' sinking or improvement funds and/or replacement funds, will become available as a basis for the issuance of additional Bonds. The Company has reserved the right to amend the Mortgage without any consent or other action by holders of any series of Bonds (including the New Bonds) other than the Bonds of the 6-1/2% Series due January 1, 1998 so as to include nuclear fuel (and similar or analogous devices or substances) as property additions. - 7 - The Mortgage contains certain restrictions upon the issuance of Bonds against property subject to liens and upon the increase of the amount of such liens. (Mortgage, Sec. 4-8, 20-30, and 46; Fifth Supplemental, Sec. 2.) Release and Substitution of Property. Property may be released upon the basis of: (1) deposit of cash or, to a limited extent, purchase money mortgages; (2) property additions, after adjustments in certain cases to offset retirement and after making adjustments for qualified lien bonds outstanding against property additions; and/or (3) waiver of the right to issue Bonds without applying any earnings test. Cash may be withdrawn upon the bases stated in (2) and (3) above. When property released is not funded property, property additions used to effect the release may again, in certain cases, become available as credits under the Mortgage, and the waiver of the right to issue Bonds to effect the release may, in certain cases, cease to be effective as such a waiver. Similar provisions are in effect as to cash proceeds of such property. The Mortgage contains special provisions with respect to qualified lien bonds pledged, and disposition of moneys received on pledged prior lien bonds. (Mortgage, Sec. 5, 31, 32, 37, 46-50, 59-63, 100 and 118.) Dividend Covenant. The Company covenants that it will not declare or pay dividends (other than dividends payable in common stock) on or make any other distributions on or acquire (unless without cost to it) any of its common stock unless the provisions for depreciation and retirement of property during the period beginning September 1, 1945 to the date of the proposed payment, distribution or acquisition, plus earned surplus of the Company (including current net income available to be transferred to earned surplus) remaining: (a) after such payment, distribution or acquisition; and (b) after deducting any remainder of the amount of earned surplus of the Company as of August 31, 1945, after deducting from such amount the charges to earned surplus subsequent to August 31, 1945, other than charges occasioned by dividends (other than dividends payable in common stock) on its common stock or occasioned by other distributions on or acquisitions of its common stock and other than charges to earned surplus with corresponding credits to reserve for depreciation and retirement of property; shall be at least equal to the amount of replacement fund requirements, if any, for such period. (See Replacement Fund.) (Mortgage, Sec. 39.) None of the Company's retained earnings as of September 30, 1996 was restricted as a result of such provisions. Modification of the Mortgage. The rights of Bondholders may be modified with the consent of the holders of 70 percent of the Bonds and, if less than all series of Bonds are affected, the consent also of the holders of 70 percent of the Bonds of each series affected. The Company has reserved the right without any consent or other action by the holders of any series of Bonds (including the New Bonds) other than the Bonds of the 6-1/2% Series due January 1, 1998 to amend the Mortgage so as to substitute 66 2/3 percent for 70 percent in the foregoing provisions. In general, no modification of the terms of payment of principal and interest, no modification of the obligations of the Company under Section 64 and no modification affecting the lien or reducing the percentage required for modification, is effective against any Bondholder without his consent. (Mortgage, Art. XIX; Fifth Supplemental, Sec. 3.) Defaults and Notice Thereof. Defaults are defined as being default in payment of principal; default for 60 days in payment of interest or of installments of funds for retirement of Bonds; certain defaults with respect to qualified lien bonds and certain events in bankruptcy, insolvency or reorganization; and default of 90 days after notice in other covenants. (Mortgage, Sec. 65.) The Trustees may withhold notice of default (except in payment of principal, interest or funds for retirement of Bonds) if they think it is in the interest of the bondholders. (Mortgage, Sec. 66.) Under the Trust Indenture Act of 1939, as amended, general periodic evidence is required to be furnished as to compliance with the conditions and covenants under the Mortgage. The Corporate Trustee or the holders of 25 percent of the Bonds may declare the principal and interest due on default, but a majority may annul such declaration if the default has been cured. (Mortgage, - 8 - Sec. 67.) No holder of Bonds may enforce the lien of the Mortgage without giving the Trustees written notice of a default and unless holders of 25 percent of the Bonds have requested the Trustees to act and offered them reasonable opportunity to act and indemnity satisfactory to the Trustees and they shall have failed to act. (Mortgage, Sec. 80.) The holders of a majority of the Bonds may direct the time, method and place of conducting any proceedings for any remedy available to the Trustees, or exercising any trust or power conferred upon the Trustees, but the Trustees are not required to follow such direction if not sufficiently indemnified for expenditures.
