S-4 RECENT DIVIDENDS AND STOCK PRICE INFORMATION The Company's Common Stock is listed on the New York Stock Exchange and the Boston Stock Exchange. The high and low sales prices of the Common Stock on the New York Stock Exchange composite tape as reported in the Eastern Edition of THE WALL STREET JOURNAL, and the dividends paid, have been as follows: PRICE -------------------- DIVIDENDS YEAR HIGH LOW PAID ----- --------- --------- ----------- 1993 First Quarter........................................................... $ 30 1/2 $ 26 3/8 $ .425 Second Quarter.......................................................... 30 7/8 27 7/8 .425 Third Quarter........................................................... 32 5/8 29 3/4 .425 Fourth Quarter.......................................................... 32 1/4 27 7/8 .425 1994 First Quarter........................................................... 29 7/8 26 .440 Second Quarter.......................................................... 29 1/8 26 .440 (through June 13, 1994) See "Dividends and Stock Price Information" in the accompanying Prospectus. The last reported sale price of the Common Stock on the New York Stock Exchange composite tape on June 13, 1994 was $27 7/8 per share. At March 31, 1994, the book value of the Company's Common Stock was $19.35 per share. RECENT DEVELOPMENTS RECENT FINANCIAL RESULTS On April 28, 1994, the Company reported earnings per common share of $0.35 and $2.37 for the three and twelve months ended March 31, 1994, respectively, versus earnings of $0.25 and $2.11 for the same periods ended March 31, 1993. The increase in 1994 first quarter earnings primarily reflects the elimination of certain purchased power expenses associated with a $60,000,000 contract that expired on October 31, 1993, an annual rate increase of $29,000,000 which became effective November 1, 1993 and a 3.1% increase in retail electricity sales due in part to weather conditions. These were partially offset by higher depreciation and amortization, due partly to the amortization of costs in 1994 associated with the cancelled Pilgrim 2 nuclear unit, for which there were no expenses in 1993 as approved by the Massachusetts Department of Public Utilities (the "MDPU"), increases in pension and other employee benefit expenses, as well as higher income tax expenses as a result of MDPU-approved adjustments that reduced the effective tax rate in 1993. MANAGEMENT CHANGES On April 28, 1994, the Company announced that Thomas J. May, the current President of the Company, had been elected Chairman and Chief Executive Officer of the Company effective July 1, 1994, and that Executive Vice President George W. Davis had been elected to serve as the Company's President and Chief Operating Officer, also effective July 1. Bernard W. Reznicek announced his retirement as Chairman and Chief Executive Officer as of July 1, 1994. S-5 USE OF PROCEEDS The Company will use the net proceeds from the sale of the shares of Common Stock offered hereby for the payment of obligations incurred under bank lines of credit and commercial paper for capital expenditures for extensions, additions and improvements to the Company's plant and properties. As of June 13, 1994, such lines of credit and commercial paper had a weighted average interest rate of 4.42% and a weighted average maturity of 20 days. LEGAL OPINIONS The validity of the shares of Common Stock offered hereby will be passed upon for the Company by Ropes & Gray, One International Place, Boston, Massachusetts, counsel for the Company, and for the Underwriters by Choate, Hall & Stewart, Exchange Place, 53 State Street, Boston, Massachusetts, counsel for the Underwriters. Thomas G. Dignan, Jr., a partner of Ropes & Gray, is a Director of the Company. EXPERTS The consolidated balance sheets of the Company as of December 31, 1993 and 1992 and the consolidated statements of income, retained earnings, and cash flows for each of the three years in the period ended December 31, 1993, have been incorporated by reference herein in reliance on the report of Coopers & Lybrand, independent accountants, given on the authority of that firm as experts in accounting and auditing. With respect to the unaudited interim consolidated financial information for the periods ended March 31, 1994 and 1993, incorporated by reference herein, Coopers & Lybrand have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 1994, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim consolidated financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Coopers & Lybrand are not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended (the "Act"), for their report on the unaudited interim consolidated financial information because such report is not a "report", or a "part" of the registration statement prepared or certified by Coopers & Lybrand within the meaning of Sections 7 and 11 of the Act.

It was incorporated in 1886 under the laws of The Commonwealth of Massachusetts. Its principal executive offices are located at 800 Boylston Street, Boston, Massachusetts 02199, and its main telephone number is (617) 424-2000. The Company supplies electricity at retail to an area of approximately 590 square miles within 30 miles of Boston, Massachusetts, encompassing the City of Boston and 39 surrounding cities and towns. The population of the territory served with electricity at retail is approximately 1,500,000. At December 31, 1992, the Company served approximately 650,000 customers. The Company also supplies electricity at wholesale for resale to other utilities and municipal electric departments. Through Harbor Electric Energy Company, a wholly owned subsidiary, the Company provides distribution service to the Massachusetts Water Resource Authority's wastewater treatment facility on Deer Island in Boston, Massachusetts. For the year ending December 31, 1992, approximately 85% of the Company's revenues were derived from retail electric sales, 13% from wholesale electric sales and 2% from other sources. Sources of installed electric generation capability in 1992 were 81% fossil and 19% nuclear. USE OF PROCEEDS The Company may use the net proceeds from the sale of the Securities offered hereby for any or all of the following purposes: (i) for the redemption, repurchase or payment at maturity of any or all of the following outstanding securities of the Company: $25,000,000 outstanding principal amount of First Mortgage Bonds, Series I, 4 3/4% due 1995; $40,000,000 outstanding principal amount of First Mortgage Bonds, Series J, 6 1/8% due 1997; $50,000,000 outstanding principal amount of First Mortgage Bonds, Series K, 6 7/8% due 1998; $50,000,000 outstanding principal amount of First Mortgage Bonds, Series L, 9% due 1999; $60,000,000 outstanding principal amount of First Mortgage Bonds, Series M, 9 3/8% due 2000; $75,000,000 outstanding principal amount of First Mortgage Bonds, Series N, 8 1/8% due 2001; $60,000,000 outstanding principal amount of First Mortgage Bonds, Series P, 9 1/4% due 2007; $59,375,000 outstanding principal amount of First Mortgage Bonds, Series Q, 9 3/4% due 2003; $44,250,000 outstanding principal amount of First Mortgage Bonds, Series R, 10.95% due 2004; $25,000,000 outstanding principal amount of First Mortgage Bonds, Series S, variable rate (currently 9.2%) due 2002; $15,000,000 outstanding principal amount of Collateralized Pollution Control Revenue Bonds, 1984 Series A (10.25%) due 2014; $135,000,000 outstanding principal amount of First Mortgage Bonds, Series W, 9 1/2% due 2016; $50,000,000 outstanding principal amount of Series A Medium Term Notes, 9.75% due 1994; and/or 400,000 outstanding shares of the Company's Cumulative Preferred Stock, 8.88% Series, or for the payment of obligations of the Company incurred for such redemptions or payments; (ii) for the payment of obligations of the Company incurred for capital expenditures for extensions, additions and improvements to the Company's plant and properties or for the payment of obligations of the Company incurred for such purposes; (iii) to make certain required and voluntary sinking fund payments in respect of the Company's issued and outstanding First Mortgage Bonds and Cumulative Preferred Stock; and/or (iv) for the repayment of short-term debt balances. As of January 29, 1993, such short-term debt balances had a weighted average interest rate of 3.36% and a weighted average maturity of 21 days. 3 PLANT EXPENDITURES AND FINANCING The Company's current estimate of plant expenditures for the period 1993 through 1996, which is subject to continuing review and adjustment, is approximately $790,000,000 (excluding allowances for funds used during construction and $64,000,000 in nuclear fuel expenditures). A significant portion of such expenditures relate to the Company's transmission and distribution system. Funds generated internally (excluding the effects of certain settlement agreements between the Company and the Massachusetts Department of Public Utilities in 1989 and the Federal Energy Regulatory Commission in 1990) represented approximately 90%, 89% and 73% of plant expenditures in 1992, 1991 and 1990, respectively. It is expected that a portion of future plant expenditures will be funded internally. It is anticipated that the balance of the Company's plant expenditures, long-term debt maturities and sinking fund requirements (the latter two items aggregating $213,535,000 for the period 1993 through 1996), will be financed by the issuance of debt and equity securities, including the Securities. RATIO OF EARNINGS TO FIXED CHARGES AND RATIO OF EARNINGS TO FIXED CHARGES AND PREFERRED DIVIDENDS* YEARS ENDED DECEMBER 31, ----------------------------------------------------- 1992 1991 1990 1989 1988 --------- --------- --------- --------- --------- Ratio of Earnings to Fixed Charges............................... 1.93x 1.86x 1.91x 0.52x 2.08x Ratio of Earnings to Fixed Charges and Preferred Dividends............................................. 1.71x 1.71x 1.73x 0.47x 1.86x Earnings have been computed by adding the amount of income taxes and fixed charges to net income. Fixed charges include gross interest expense and the estimated interest component of rentals. The Company reported a loss for the year ended December 31, 1989, primarily as a result of a charge of $178,650,000 reflecting the settlement of certain regulatory and legal proceedings. Excluding the effects of such charge, the Ratio of Earnings to Fixed Charges and the Ratio of Earnings to Fixed Charges and Preferred Dividends for 1989 would have been 2.06x and 1.86x, respectively. The Company would have needed to generate additional pre-tax income of $55,708,000 and $68,183,000, to cover its fixed charges of $116,445,000 and fixed charges and preferred dividends of $128,921,000, respectively, in 1989. - ------------------------ *No shares of the Company's Preference Stock are currently outstanding, although shares of Preference Stock were outstanding during each of the periods listed above. The Ratio of Earnings to Fixed Charges and Preferred and Preference Dividends for each of the years ended December 31, 1992, 1991, 1990, 1989 and 1988 were 1.69x, 1.60x, 1.59x, 0.43x and 1.76x, respectively. The Company would have needed to generate additional pre-tax income of $79,784,000 to cover its fixed charges and preferred and preference dividends of $140,522,000 in 1989. 4 DIVIDENDS AND STOCK PRICE INFORMATION The Company's Common Stock is listed on the New York Stock Exchange and the Boston Stock Exchange.

Unless otherwise indicated in a Prospectus Supplement relating thereto, the New Debt Securities will be issued only in fully registered form, without coupons, in denominations of $1,000 or any multiple thereof, will be registered for transfer or exchange, and principal and interest, if any, will be payable at the Corporate Trust Office of the Trustee in the City of New York, 77 Water Street, New York, New York 10005. No service charge will be made for any transfer or exchange of the Debt Securities, but the Company may require payment of a sum sufficient to cover any tax or other government charge payable in connection therewith. Unless otherwise indicated in a Prospectus Supplement relating to a series of New Debt Securities (the "Offered Debt Securities"), there are no provisions in the Indenture that require the Company to redeem, or permit the holders to cause a redemption of, the New Debt Securities or that otherwise protect the holders in the event that the Company incurs substantial additional indebtedness, whether or not in connection with a change in control of the Company. Certain other terms and provisions of the New Debt Securities, including the maturity, rate of interest, interest payment dates, redemption provisions and whether any of the Debt Securities are to be issuable in permanent global form, will be described in a Prospectus Supplement relating to such New Debt Securities. EVENTS OF DEFAULT The following constitute Events of Default under the Indenture with respect to Debt Securities of any series: (1) default in the payment of principal of any Debt Security when due and the continuation of such default for a period of three Business Days thereafter; (2) default in the payment of interest on any Debt Security when due and the continuation thereof for a period of 30 days; (3) default in the payment of any sinking fund payment when due by the terms of the Debt Securities of the series; (4) default in the performance or breach of any covenant or warranty of the Company in the Indenture (other than a covenant or warranty included in the Indenture solely for the benefit of one or more series of Debt Securities other than the Offered Debt Securities), and the continuation thereof for 60 days after written notice to the Company as provided in the Indenture; (5) default in the payment of principal or interest on, or acceleration of, securities of any other series issued under the Indenture or any other mortgage, indenture or instrument or other evidence of indebtedness of the Company for borrowed money, in an aggregate amount exceeding $10,000,000, which default is not cured or acceleration not rescinded or annulled, or indebtedness not discharged, within 90 days after written notice to the Company as provided in the Indenture; (6) certain events of bankruptcy, insolvency or reorganization; and (7) any other Event of Default provided with respect to Debt Securities of a particular series. If an Event of Default with respect to the Debt Securities occurs and is continuing, either the Trustee or the Holders of at least 33% in aggregate principal amount of the outstanding Debt Securities may declare the principal amount of all Debt Securities to be due and payable immediately. At any time after the declaration of acceleration with respect to the Debt Securities has been made, but before a judgment or decree based on acceleration has been obtained, the Holders of a majority in principal amount of the outstanding Debt Securities may, under certain circumstances, rescind and annul such acceleration. The Indenture provides that, subject to the duty of the Trustee during default to act with the required standard of care, the Trustee will be under no obligation to exercise any of its rights or powers under the 6 Indenture at the request or direction of any of the Holders of the outstanding Debt Securities, unless such Holders shall have offered to the Trustee reasonable indemnity. Subject to such provisions for the indemnification of the Trustee, the Holders of 33% in principal amount of the outstanding Debt Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Debt Securities. The right of a Holder of any Debt Security to institute a proceeding with respect to the Indenture is subject to certain conditions precedent, but each Holder of a Debt Security has an absolute right to receive payment of principal and interest when due and to institute suit for the enforcement of any such payment. The Indenture provides that the Trustee, within 90 days after the occurrence of a default with respect to the Debt Securities, is required to give the Holders of the Debt Securities notice of such default, unless cured or waived; provided that, except in the case of default in the payment of principal or interest on any Debt Security, the Trustee may withhold such notice if it determines it is in the interest of such Holders to do so. The Company will be required to furnish annually to the Trustee a statement as to the performance by the Company of certain of its obligations under the Indenture and as to default in such performance. CONSOLIDATION, MERGER, SALE OR CONVEYANCE The Indenture provides that the Company may not, without the consent of the Holders of not less than a majority in principal amount (calculated as provided in the Indenture) of the Outstanding Securities (as defined in the Indenture), consolidate with or merge into any other corporation or convey, transfer or lease its properties and assets substantially as an entirety, unless (i) if the Company is not the continuing corporation, the successor corporation shall assume by a supplemental indenture the Company's obligations under the Indenture and (ii) immediately after giving effect to such transaction, no Event of Default, and no event which after notice or lapse of time would become an Event of Default, shall have occurred and be continuing. MODIFICATION OF THE INDENTURE The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in principal amount (calculated as provided in the Indenture) of the Outstanding Securities (as defined in the Indenture), if all series of Outstanding Securities are affected, or the Holders of a majority in aggregate principal amount of each series affected by such modification, in case one or more, but less than all, of the series of Outstanding Securities are affected, to modify the Indenture or any supplemental indenture or the rights of the Holders of the Outstanding Securities of any series; provided that no such modification shall, without the consent of the Holders of each Outstanding Security affected thereby, change the maturity of any Outstanding Security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable upon redemption of any Outstanding Security, or reduce the overdue rate thereof or change the currency of payment of principal or interest on any Outstanding Security or reduce the above stated percentage in principal amount of Outstanding Securities the consent of the Holders of which is required for modification or amendment of the Indenture or for waiver of certain defaults, or change any obligation of the Company to maintain an office or agency in each Place of Payment. The Indenture also permits the Company and the Trustee to amend the Indenture in certain circumstances without the consent of the Holders of any Debt Securities to evidence the merger of the Company or the replacement of the Trustee and for certain other purposes. CONCERNING THE TRUSTEE Bank of Montreal Trust Company is the Trustee and Paying Agent under the Indenture. The bank or one of its affiliates has had a regular course of commercial dealings with the Company including participation in its revolving credit agreement, and from time to time its working lines of credit. 7 DESCRIPTION OF CUMULATIVE PREFERRED STOCK GENERAL The description set forth below of certain provisions of the Company's Restated Articles of Organization, as amended, the laws of The Commonwealth of Massachusetts and the regulations of the Massachusetts Department of Public Utilities does not purport to be complete and is subject to, and qualified in its entirety by reference to, the Company's Restated Articles of Organization, as amended, the laws of The Commonwealth of Massachusetts and the regulations of the Massachusetts Department of Public Utilities.

GENERAL The Company may, at its option, elect to offer fractional interests in shares of the New Preferred Stock by means of the issuance of Depositary Shares. The shares of any series of the New Preferred Stock underlying the Depositary Shares will be deposited under a separate Deposit Agreement (the "Deposit Agreement") between the Company and a bank or trust company selected by the Company (the "Depositary"). The Prospectus Supplement relating to a series of Depositary Shares will set forth the name and address of the Depositary. Subject to the terms of the Deposit Agreement, each owner of a Depositary Share will be entitled proportionately to all the rights and preferences of the Cumulative Preferred Stock underlying such Depositary Share (including dividend, voting, redemption, conversion and liquidation rights). The Depositary Shares will be evidenced by Depositary Receipts issued pursuant to the Deposit Agreement, each of which will represent the fractional interest in a share of a particular series of the New Preferred Stock described in the Prospectus Supplement. DIVIDENDS The Depositary will distribute all cash dividends or other cash distributions received in respect of the New Preferred Stock to the record holders of Depositary Receipts relating to such New Preferred Stock in proportion to the numbers of such Depositary Shares owned by such holders on the relevant record date. The Depositary shall distribute only such amount, however, as can be distributed without attributing to any holder of Depositary Shares a fraction of one cent, and any balance not so distributed shall be added to and treated as part of the next sum received by the Depositary for distribution to holders of Depositary Shares. REDEMPTION OF DEPOSITARY SHARES If a series of the New Preferred Stock underlying the Depositary Shares is subject to redemption, the Depositary Shares will be redeemed from the proceeds received by the Depositary resulting from the redemption, in whole or in part, of such series of the New Preferred Stock held by the Depositary. The redemption price per Depositary Share will be equal to the applicable fraction of the redemption price per share payable with respect to such series of the New Preferred Stock. If less than all the Depositary Shares are to be redeemed, the Depositary Shares to be redeemed will be selected by lot by the Board of Directors. VOTING Upon receipt of notice of any meeting at which the holders of the Cumulative Preferred Stock are entitled to vote, the Depositary will mail the information contained in such notice of meeting to the record holders of the Depositary Receipts evidencing Depositary Shares relating to such Cumulative Preferred Stock.

The Depositary will endeavor, insofar as practicable, to vote the amount of Cumulative Preferred Stock underlying such Depositary Shares in accordance with such instructions, and the Company will agree to take all action which may be deemed necessary by the Depositary in order to enable the Depositary to do so. The Depositary will abstain from 11 voting the Cumulative Preferred Stock to the extent that it does not receive specific instructions from the holders of the Depositary Receipts evidencing Depositary Shares representing such Cumulative Preferred Stock. WITHDRAWAL OF CUMULATIVE PREFERRED STOCK Upon surrender of Depositary Receipts at the Corporate Office of the Depositary and upon payment of the Depositary's customary charges therefor, and subject to the terms of the Deposit Agreement, the owner of the Depositary Shares evidenced thereby is entitled to delivery of the number of whole shares of Cumulative Preferred Stock represented by such Depositary Shares. Owners of Depositary Shares will be entitled to receive only whole shares of Cumulative Preferred Stock on the basis of one share of Cumulative Preferred Stock for the number of Depositary Shares specified in the Prospectus Supplement relating to such Depositary Shares. Partial shares of Cumulative Preferred Stock will not be issued. If the Depositary Receipts delivered by the holder evidence a number of Depositary Shares in excess of the number of Depositary Shares representing the number of whole shares of Cumulative Preferred Stock to be withdrawn, the Depositary will deliver to such holder at the same time a new Depositary Receipt evidencing such excess number of Depositary Shares. Holders of shares of Cumulative Preferred Stock thus withdrawn will not thereafter be entitled to deposit such shares under the Deposit Agreement or to receive Depositary Receipts evidencing Depositary Shares therefor. AMENDMENT OF FORM OF DEPOSITARY RECEIPTS AND OF DEPOSIT AGREEMENT The form of Depositary Receipt evidencing the Depositary Shares and any provision of the Deposit Agreement may at any time be amended by agreement between the Company and the Depositary, provided, however, that any amendment which materially and adversely alters the rights of the existing holders of Depositary Shares will not be effective unless such amendment has been approved by holders of at least a majority of the Depositary Shares then outstanding. CHARGES OF DEPOSITARY The Company will pay all transfer and other taxes and governmental charges that arise solely from the existence of the depositary arrangements. The Company will pay charges of the Depositary in connection with the initial deposit of the Cumulative Preferred Stock, the initial issuance of the Depositary Receipts and any redemption of the Cumulative Preferred Stock. Holders of Depositary Shares will pay all other transfer and other taxes and governmental charges, and, in addition, such other charges as are expressly provided in the Deposit Agreement to be for their accounts. TAXATION Owners of Depositary Shares will be treated for Federal income tax purposes as if they were owners of the Cumulative Preferred Stock represented by such Depositary Shares and, accordingly, will be entitled to take into account for Federal income tax purposes income and deductions to which they would be entitled if they were holders of such Cumulative Preferred Stock. In addition, (i) no gain or loss will be recognized for Federal income tax purposes upon the withdrawal of Cumulative Preferred Stock in exchange for Depositary Shares as provided in the Deposit Agreement, (ii) the tax basis of each share of Cumulative Preferred Stock to an exchanging owner of Depositary Shares will, upon such exchange, be the same as the aggregate tax basis of the Depositary Shares exchanged therefor, and (iii) the holding period for shares of the Cumulative Preferred Stock in the hands of an exchanging owner of Depositary Shares who held such Depositary Shares at the time of the exchange thereof for Cumulative Preferred Stock will include the period during which such person owned such Depositary Shares. MISCELLANEOUS The Company, or at the option of the Company, the Depositary, will forward to the holders of Depositary Shares all reports and communications from the Company which the Company may be required to furnish to the holders of the Cumulative Preferred Stock. Neither the Depositary nor the Company will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the Deposit Agreement.

Except as provided by Massachusetts law or in the Restated Articles of Organization of the Company, holders of the Common Stock shall have the exclusive right to vote for the election of Directors and for any other purpose or on any other subject. The Restated Articles of Organization provide, however, that whenever dividends on any shares of any series of the Cumulative Preferred Stock shall have accrued and remain unpaid in an amount equal to six full quarterly dividends thereon, holders of the Cumulative Preferred Stock shall have the exclusive right, voting separately as a class, to elect a majority of the Directors until all dividends in default thereon shall have been paid or declared and set apart for payment, and the remaining Directors shall be elected by the holders of the Common Stock.

The Company is also subject to (i) Chapter 110D of the Massachusetts General Laws, that, in general, prevents anyone who acquires 20% or more of a company's shares from voting those shares unless disinterested stockholders (excluding the bidder and the company's management) vote to enfranchise the bidder, and (ii) Chapter 110F of the Massachusetts General Laws, that, in general, provides that for three years after an acquiror has purchased 5% or more of the stock of a company, the acquiror may not complete the acquisition through merger, sell or pledge the assets of the company, or engage in other self-dealing transactions.

Application will be made for listing on such exchanges of additional shares of Common Stock offered in a Prospectus Supplement relating to this Prospectus. The Transfer Agent and Registrar for the Company's capital stock, including the Common Stock, is The First National Bank of Boston, 100 Federal Street, Boston, Massachusetts 02110.

LEGAL OPINIONS The validity of the Securities will be passed upon for the Company by Ropes & Gray, One International Place, Boston, Massachusetts, counsel for the Company. Thomas G. Dignan, Jr., a partner of Ropes & Gray, is a Director of the Company. Certain legal matters will be passed upon for the underwriters and/or agents by Choate, Hall & Stewart, Exchange Place, 53 State Street, Boston, Massachusetts. 14 EXPERTS The consolidated balance sheets as of December 31, 1992 and 1991 and the consolidated statements of income, retained earnings, and cash flows for each of the three years in the period ended December 31, 1992, incorporated by reference in this Prospectus, have been incorporated herein in reliance on the report of Coopers & Lybrand, independent accountants, given on the authority of that firm as experts in accounting and auditing. With respect to the unaudited interim consolidated financial information for the periods ended September 30, 1992 and 1991, June 30, 1992 and 1991, and March 31, 1992 and 1991, incorporated by reference in this Prospectus, Coopers & Lybrand have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports included in the Company's Quarterly Reports on Form 10-Q for the quarters ended September 30, 1992, June 30, 1992 and March 31, 1992, and incorporated by reference herein, state that they did not audit and they do not express an opinion on that interim consolidated financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Coopers & Lybrand are not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended (the "Act"), for their reports on the unaudited interim consolidated financial information because such reports are not "reports" or a "part" of the registration statement prepared or certified by Coopers & Lybrand within the meaning of Sections 7 and 11 of the Act. Ropes & Gray has reviewed the statements as to matters of law and legal conclusions under "Description of Debt Securities", "Description of Cumulative Preferred Stock", "Description of Depositary Shares", and "Description of Capital Stock." Such statements are included on the authority of said firm. PLAN OF DISTRIBUTION The Company may sell the Securities to or through underwriters, and also may sell the Securities directly to other purchasers or through agents. The distribution of the Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. In connection with the sale of the Securities, underwriters or agents may receive compensation from the Company or from purchasers of the Securities for whom they may act as agents in the form of discounts, concessions or commissions. Underwriters may sell the Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the Securities may be deemed to be underwriters, and any discounts or commissions received by them from the Company and any profit on the resale of the Securities by them may be deemed to be underwriting discounts and commissions under the Act. Any such underwriter or agent will be identified, and any such compensation received from the Company will be described, in a Prospectus Supplement. Under agreements which may be entered into by the Company, underwriters and agents who participate in the distribution of the Securities may be entitled to indemnification by the Company against certain liabilities, including liabilities under the Act. If so indicated in a Prospectus Supplement, the Company will authorize underwriters or other persons acting as the Company's agents to solicit offers by certain institutions to purchase the Securities from the Company pursuant to contracts providing for payment and delivery on a future date.
