Box 9150, Cambridge, Massachusetts 02142-9150 or by calling the appropriate toll-free number listed below: 1-800-447-1183 (outside Massachusetts) 1-800-336-3773 (within Massachusetts) THE SYSTEM Commonwealth Energy System (the System), a Massachusetts trust with offices at One Main Street, Cambridge, Massachusetts 02142-9150 (telephone number 617-225-4000), is an unincorporated business organization with transferable shares. The System is organized as a business trust under a Declaration of Trust dated December 31, 1926, as amended, pursuant to the laws of Massachusetts. The System is an exempt holding company under the provisions of the Public Utility Holding Company Act of 1935, holding investments in common stock of four operating public utility companies and a steam distribution company: Cambridge Electric Light Company, Canal Electric Company, Commonwealth Gas Company, Commonwealth Electric Company and COM/Energy Steam Company. All of these subsidiaries are wholly-owned by the System. The System also owns all of the capital stock of a services company, an LNG service company and five real estate trusts. USE OF PROCEEDS The net proceeds received upon the direct issue of the System's Common Shares will be advanced by the System to subsidiary companies. The subsidiary companies will use the advances for the purpose of financing additions to property, plant and equipment and for general working capital needs. Where the System elects to forward the reinvested dividends and/or optional cash payments to a Purchasing Representative who will purchase Common Shares of the System on the open market at prevailing market prices, the System will receive no proceeds to advance to subsidiary companies. DESCRIPTION OF THE PLAN The following thirty numbered questions and answers constitute the provisions of the Plan. Shareholders presently enrolled in the Plan need take no action to continue to participate in the Plan. Purpose 1. What is the purpose of the Plan? The purpose of the Plan is to provide holders of record of Common Shares of the System with a simple and convenient method of either investing cash dividends on those Common Shares or making optional cash payments, or both, to purchase additional Common Shares of the System without payment of any brokerage commissions, fees, service charges or other expenses. In the event <PAGE 5> that these funds are used to purchase Common Shares directly from the System, the proceeds will be advanced to subsidiary companies for their continuing construction programs and for general working capital needs. (See Question 26 for tax consequences of participation in the Plan.) Advantages 2. What are the advantages of the Plan? Participants in the Plan may (a) have cash dividends on Common Shares automatically reinvested, or (b) continue to receive cash dividends on Common Shares and make optional cash payments which will be invested monthly, or (c) invest both cash dividends on Common Shares and optional cash payments. No brokerage commissions, fees, service charges, or other expenses are paid by participants in connection with purchases under the Plan. Commissions paid by the Plan in the event of open market purchases by the Purchasing Representative will be taxable to Plan participants. (See Question 26 for additional information.) Full investment of funds is possible under the Plan because the Plan permits fractional shares, as well as whole shares, to be credited to participants' accounts. In addition, dividends on whole and fractional shares held in participants' Plan accounts will be reinvested in additional shares and such shares will be credited to participants' accounts. Participants avoid the necessity for safekeeping of certificates for shares held in their accounts under the Plan. The Statements of Account provide simplified recordkeeping. Investment Date and Purchase Price 3. What will be the Investment Date and price of Common Shares purchased under the Plan? The Investment Date will be the first day of each month. Cash dividends on Common Shares will be reinvested as of the first day of each month in which a dividend is paid (dividends are normally paid on the first day of February, May, August and November). Optional cash payments will be invested as of the first day of each month following receipt by the System. The price of Common Shares issued directly by the System will be the average of the high and low sale prices as reported on the New York Stock Exchange composite transactions tape on the Investment Date (or the next preceding day on which the System's Common Shares were traded if there is no trade reported on the composite transactions tape on the Investment Date). The price of Common Shares purchased on the open market will be based on the prevailing market prices at which the Purchasing Representative acquires the Common Shares. No interest will be paid on cash payments received by the System. <PAGE 6> Administration 4. Who administers the Plan for participants? The System, as agent, administers the Plan for participating shareholders. The System keeps a continuing record of participants' accounts, prepares and sends Statements of Account to participants and performs other duties relating to the Plan, including, when appropriate, the forwarding of cash dividends on Common Shares and optional cash payments to the Purchasing Representative. The Purchasing Representative acts on behalf of participants in buying Common Shares of the System on the open market at prevailing market prices. Common Shares purchased under the Plan will be registered in the name of a nominee of the System. Participation 5. Who is eligible to participate? All holders of record of Common Shares of the System are eligible to participate in the Plan. In order to be eligible to participate, beneficial owners of Common Shares of the System whose shares are registered in names other than their own (e.g., in the name of a broker or bank nominee) must become shareholders of record by having their shares registered in their names. 6. How does an eligible shareholder participate? Shareholders of record may join the Plan by signing an Authorization Form and returning it to Commonwealth Energy System, Dividend Reinvestment Plan, P.O. Box 9150, Cambridge, Massachusetts 02142-9150. An Authorization Form may be obtained at any time by written request to the System or by telephoning Shareholder Services at the appropriate toll-free number listed on page 4 of this Prospectus. Shareholders already enrolled in the Plan need take no action to continue to participate in the Plan. 7. What does the Authorization Form provide? The signed Authorization Form allows a shareholder to join the Plan and select a form of participation. A signed Authorization Form on which the "Dividend Reinvestment and Optional Cash Payment" box is checked, indicating full participation, directs the System to reinvest all of the participant's cash dividends on the Common Shares then or subsequently registered in the shareholder's name and to receive and invest any optional cash payments the participant chooses to make. Reinvestment of a portion of a participant's cash dividends on Common Shares may be accommodated upon request. A signed Authorization Form on which the "Optional Cash Payment Only" box is checked, indicating participation through optional cash payments only, directs the System to continue to send cash dividends on Common Shares to the shareholder of those Common Shares registered in the shareholder's name and to <PAGE 7> receive and invest only such optional cash payments as the participant chooses to make. Regardless of the form of participation elected, the Authorization Form directs that all dividends paid on Common Shares credited to a participant's account under the Plan will be reinvested for the participant. 8. When may a shareholder join the Plan? A shareholder of record of Common Shares may join the Plan at any time. In order to have cash dividends on Common Shares reinvested, the signed Authorization Form must be received by the System by the fifteenth of the month preceding a dividend payment date. Otherwise, the participant will receive that particular dividend in cash; subsequent dividends, however, will be reinvested (Common Share dividends are normally paid on the first day of February, May, August and November). Cash Dividends 9. How are cash dividends on Common Shares reinvested? Cash dividends will be used to purchase Common Shares of the System in either of the following ways as determined by the System: a.) Open Market Purchases: The System will forward the cash dividends on Common Shares of Plan participants to the Purchasing Representative. The Purchasing Representative will then purchase Common Shares on the open market at prevailing market prices as promptly as it deems advisable, but no later than the last day of the month in which a dividend is paid. The purchase will be consistent with and subject to the Purchasing Representative's fiduciary obligations, market conditions and the requirements of Federal securities laws. All Common Shares purchased in this manner will be allocated to the accounts of participants, and will be deemed invested for income tax purposes on the Investment Date. b.) Direct Issue Purchases: On each dividend payment date, the System will apply the dividends on Common Shares held in a participant's Plan account to the direct issue of additional Common Shares. Optional Cash Payments 10. How does the optional cash payment work? Optional cash payments may be made in varying amounts of at least $10 per payment but not more than $5,000 per month. There is no obligation to make an optional cash payment each month. Optional cash payments will be used to purchase Common Shares of the System in either of the following ways as determined by the System: <PAGE 8> a.) Open Market Purchases: On each Investment Date, the System will forward any optional cash payments received prior to such Investment Date to the Purchasing Representative. The Purchasing Representative will then purchase Common Shares of the System on the open market at prevailing market prices as promptly as it deems advisable but no later than the last day of the month, consistent with and subject to the Purchasing Representative's fiduciary obligations, market conditions and the requirements of federal securities laws. All Common Shares purchased in this manner will be allocated to the accounts of participants, and will be deemed invested for income tax purposes on the Investment Date. If the "Optional Cash Payment Only" box on the Authorization Form is checked, the System will continue in the usual manner to pay cash dividends on those Common Shares registered in the participant's name, but the dividends on Common Shares held in a participant's Plan account will be forwarded to the Purchasing Representative for investment at prevailing market prices. b.) Direct Issue Purchases: On each Investment Date, the System will apply any optional cash payment received prior to such Investment Date to the direct issue of additional Common Shares of the System for the account of the participant. If the "Optional Cash Payment Only" box on the Authorization Form is checked, the System will continue to pay cash dividends on those Common Shares registered in the participant's name, but the dividends on Common Shares held in a participant's Plan account will be applied to the direct issue of Common Shares from the System for the account of the participant. 11. How are optional cash payments made? The option to make cash payments will be available to participants each month. Optional cash payments by a participant must be at least $10 per payment and may not exceed a total of $5,000 per month. The $10 minimum will be waived for foreign participants (see Question 27). Upon enrollment, a participant may make an initial optional cash payment by enclosing a check with the Authorization Form. A cash payment acknowledgement form and return envelope (for subsequent optional cash payments) will be mailed to a participant after each optional cash payment. Following the investment of the optional cash payment, the System will also send a current Statement of Account to the participant. Subsequent optional cash payments may also be made by removing the top portion of the Statement of Account showing the participant's name, address and account number and returning the completed form with a check to the System in the return envelope provided. Checks for optional cash payments must be made payable to CES-DRP, and mailed to Commonwealth Energy System, Dividend Reinvestment Plan, P.O. Box 9150, Cambridge, Massachusetts 02142-9150. Please do not send cash. <PAGE 9> If a participant's written request is received by the System prior to the Investment Date, any optional cash payment which would otherwise be invested will be returned to the participant. 12. What will be done with optional cash payments which are received late? Optional cash payments received by the System on or after the Investment Date will be held until the next Investment Date unless the participant requests that the payment be returned under both the open market or direct issue methods. No interest will be paid on optional cash payments. In order to assure that optional cash payments are received by the System prior to any Investment Date, it is suggested that participants should allow sufficient time for mail delivery. Costs 13. Are there any expenses to participants in connection with purchases under the Plan? No. There are no brokerage commissions, fees, service charges or other expenses when Common Shares are purchased through the Plan. All costs of administration of the Plan are to be paid by the System. However, commissions paid by the Plan in the event of open market purchases by the Purchasing Representative will be taxable to Plan participants. Purchases 14. How many Common Shares will be purchased for a participant? The participant cannot specify the number of shares to be purchased because the number of shares purchased depends on the amount of the participant's dividend and/or optional cash payments, as well as the purchase price of the Common Shares. Each participant's account will be credited with that number of shares, including fractions computed to three decimal places, equal to the total amount to be invested divided by the purchase price. Reports to Participants 15. How will participants be advised of their purchase of Common Shares? As soon as practicable after the Investment Date, the participant will receive an acknowledgement form from the System. A Statement of Account will be sent to the participant following activity in the Plan which may be optional cash payments or the reinvestment of cash dividends on Common Shares. These statements are the participant's continuing record of the cost of Common Share purchases and should be retained for income tax purposes. 16. What other communications will participants receive? Each participant will receive a copy of a current Prospectus. Following each dividend payment date, a copy of the System's current Quarterly Report to Shareholders will be mailed with a current Statement of Account. The mailing will include any supplements or amendments to the current Prospectus. In addition, the participant will receive the same communications as every other shareholder, including the System's Annual Report to Shareholders, a Notice of <PAGE 10> Annual Meeting of Shareholders and Proxy Statement, a proxy card (see Question 25), and income tax information forms (see Question 26) reporting dividend information. Dividends 17. Will participants be credited with dividends on the fractional shares held in the Plan? Yes. It should be noted that the dividends are computed on the total number of shares which are owned. It makes no difference whether the participant holds the certificates for the shares or the shares are held in the Plan. Certificates for Shares 18. Will certificates be issued for Common Shares purchased? Normally, certificates for Common Shares purchased under the Plan will not be issued to participants. The number of shares held in a participant's account under the Plan will be shown on the participant's Statement of Account. Certificates for any number of whole shares credited to a participant's account under the Plan will be issued upon the written request of such participant. A participant may use the reverse side of the top portion of the Statement of Account for this purpose. The issuance of such certificates will not terminate the participant's continuation in the Plan. Any request for the issuance of certificates should be mailed to Commonwealth Energy System, Dividend Reinvestment Plan, P.O. Box 9150, Cambridge, Massachusetts 02142- 9150. Any remaining whole shares and any fractional share will continue to be held in the participant's account. Certificates for fractional shares will not be issued under any circumstances. Shares held in the account of a participant may not be readily transferable until a certificate is issued and may not be acceptable as collateral for loans. A participant who wishes to sell or pledge such shares should request that certificates for such shares be issued in the participant's name. 19. In whose name will certificates be registered when issued? Accounts under the Plan are maintained in the names in which certificates of the participants were registered at the time they entered the Plan. Consequently, certificates for whole shares issued upon the request of a participant will only be registered in the name of the participant. A participant desiring to transfer shares held in the Plan must contact Shareholder Services in writing and request that the shares be transferred to the new account. <PAGE 11> Withdrawal 20. When may a participant withdraw from the Plan? A participant may withdraw from the Plan at any time by giving written notice to the System. If a request to withdraw is received by Shareholder Services prior to the Record Date for any dividend that would otherwise be reinvested for a participant, the reinvestment feature will be terminated within a reasonable time after receipt of the request so as to provide for the payment of a cash dividend for the next quarter. If the request to withdraw is received by Shareholder Services on or after the Record Date, the dividend paid on the dividend payment date will be reinvested for the participant's account. The request for termination will take effect prior to the next dividend payment. Any optional cash payment which had been sent to Shareholder Services prior to the receipt by the System of the request for termination will be returned to the participant if it is practicable to do so. Following withdrawal from the Plan, all subsequent dividends will be paid to the shareholder in cash unless and until the shareholder elects to re- enroll in the Plan (see Question 8). 21. How does a participant withdraw from the Plan? In order to withdraw from the Plan, a participant must write to Commonwealth Energy System, Dividend Reinvestment Plan, P.O. Box 9150, Cambridge, Massachusetts 02142-9150, giving notice of the desire to withdraw from the Plan and listing the account number. A participant may use the reverse side of the top portion of the Statement of Account for this purpose. When a participant withdraws from the Plan, or upon termination of the Plan by the System, certificates for whole shares credited to the participant's account under the Plan will be issued and a cash payment will be made for any fractional share (see Question 22). The System will not repurchase or sell for any participant any full shares credited to the participant's account in the Plan. 22. What happens to a fractional share when a participant withdraws from the Plan or the Plan is terminated? When a participant withdraws from the Plan, a cash payment representing the proceeds from the sale of any fractional share will be mailed directly to the participant. This cash payment will be based on the most recent closing price of the System's Common Shares on the New York Stock Exchange composite transactions tape when the withdrawal request is received by the System. Adjustments for fractional shares would also be made upon termination of the Plan. Other Information 23. How can a participant sell or transfer all of the shares registered in the participant's name? If a participant chooses to sell all of the shares registered in the participant's name, the participant must first withdraw from the Plan (see Questions 20 through 22). The System will not sell for any participant any full shares credited to the participant's account in the Plan. <PAGE 12> If a participant wants to transfer all of the shares held in a joint account in the Plan, the participant must notify the System in writing. Any such written requests should be mailed to Commonwealth Energy System, Dividend Reinvestment Plan, P.O. Box 9150, Cambridge, Massachusetts 02142-9150. Until the System receives notification from the participant to do otherwise, the System will continue to reinvest the dividends on the shares credited to the account of the participant under the Plan. 24. What happens if the System issues a stock dividend, declares a stock split or has a rights offering? Stock dividends distributed on shares registered in the name of a participant on the books of the System, as well as shares distributed on account of any split of such shares, and warrants issued for rights applicable to such shares in a rights offering, will be mailed directly to the shareholder. Stock dividends on shares credited to a participant's account in the Plan, or upon any split of such shares, will be credited to the participant's account. A participant's entitlement in a rights offering will be based upon the participant's total holdings--those registered in the participant's name on the books of the System and those credited to the participant's account under the Plan. However, rights will be issued for the number of whole shares only and rights based on a fractional share held in a participant's account will be sold for the participant's account and the new proceeds will be applied as an optional cash payment to purchase Common Shares under the Plan on the next Investment Date. 25. How will a participant's shares be voted at shareholders' meetings? A single proxy for all of the participant's shares--those registered in the participant's name, if any, and those credited to the account of the participant under the Plan--will be sent to each participant prior to each shareholders' meeting. The participant may vote these shares in accordance with this proxy or may vote in person at the shareholders' meeting. 26. What are the federal income tax consequences of participation in the Plan? a.) General: A participant who did not elect or who was not eligible for the treatment of reinvested dividends described in paragraph b, below, will be treated, for federal income tax purposes, as having received on the Investment Date a dividend equal to the full amount of the cash dividend paid even though that amount is not actually received by the participant in cash but, instead, is applied to the purchase of shares for the participant's account. Also, if Common Shares are purchased on the open market, a participant's share of any brokerage commissions paid by the System will be taxed as dividend income to the participant. A participant will not realize any taxable income upon receiving certificates for whole shares, either upon the participant's request for certificates for those shares or upon withdrawal from or termination of the Plan. However, a participant may realize ordinary income or a capital gain or <PAGE 13> loss for a cash payment that is made in settlement of a fractional share upon withdrawal from or termination of the Plan. Ordinary income or capital gain or loss may also be realized upon withdrawal from the Plan, when any or all whole shares are sold by the participant. The amount of income, capital gain or loss will be the difference between the amount received and the tax basis for both the fractional and whole shares which are sold. b.) Individuals Who Elected to Defer Taxes on Reinvested Dividends: The Economic Recovery Tax Act of 1981 provided that dividends reinvested in newly issued shares of certain qualified reinvestment plans, such as the System's, could be excluded from taxable income. The participant could elect to exclude up to $750 per year ($1,500 on a joint return). This exclusion, which began in 1982, expired after the 1985 tax year. If a participant elected to defer the taxes on reinvested dividends pursuant to this exclusion, Common Shares purchased with those dividends have a zero tax basis. c.) Tax Information Forms: Following each tax year, the System sends each participant a U.S. Information Return (Form 1099-DIV.) reporting the taxable dividends for that tax year. This form contains the information necessary to complete the dividend income information on the participants' federal income tax return. Generally, the amount in the box labeled "Total Dividends For The Calendar Year" should be included on a participant's federal income tax return as taxable income. For additional information and any questions regarding the tax consequences of participation in the Plan, participants should consult their own tax advisors. 27. What provision is made for foreign participants whose dividends are subject to income tax withholding? In the case of those foreign participants whose dividends are subject to United States income tax withholding, the System will apply the net amount of the dividend of such participants, after the deduction of taxes, to the purchase of Common Shares. If such foreign participants desire to invest the full amount of their dividends, they may tender cash payments in United States dollars to the System equal to the amount of tax withheld. The minimum cash payment requirement of $10 will be waived to accommodate all payments, regardless of size, made by foreign shareholders for this express purpose. Such payments will be invested for the foreign participants on the Investment Date if received by the System prior to that date. In addition, foreign participants may, of course, make optional cash payments in United States dollars. 28. What are the responsibilities of the System under the Plan? In administering the Plan, the System will not be liable for any act done in good faith or for any good faith omission to act, including, without limitation, any claim of liability arising out of failure to terminate a participant's account upon the participant's death prior to receipt of notice in writing of such death. <PAGE 14> The participant should recognize that the System cannot assure profit or protect against a loss on the Common Shares purchased by the participant under the Plan. Adoption of the Plan does not constitute any assurance that dividends will be paid in the future or that they will be paid on the same dividend payment dates as in the past. 29. Who interprets and regulates the Plan? The System reserves the right to interpret and regulate the Plan as deemed desirable or necessary. Any such interpretation or regulation made in good faith by the System will be binding upon all participants. 30. May the Plan be changed or discontinued? Although the System hopes that shareholder response will justify continuing the Plan indefinitely, the System reserves the right to suspend or terminate the Plan at any time. The System may also make modifications to the Plan. No such modifications may impair the rights of the participants with respect to investments theretofore made under the Plan. Any such suspension, termination or modification will be communicated to all shareholders, both participants and non-participants. DESCRIPTION OF COMMON SHARES The following is a brief summary of certain provisions of the System's Declaration of Trust affecting the Common Shares of Beneficial Interest, $4 par value. Dividend Rights and Limitations on Payment of Dividends Subject to the dividend and sinking fund requirements of the System's Cumulative Preferred Shares (the Preferred Shares), the holders of the Common Shares may receive out of funds legally available for the payment of dividends such dividends as may from time to time be declared by the Trustees of the System. Under the System's $40 Million Note Agreement (privately placed Senior Notes), dated June 28, 1989, the System may pay or declare a dividend if no event of default is existing or to the extent that the aggregate of all dividend declarations, payments and distributions after December 31, 1988 shall not exceed the Company's aggregate Consolidated Net Income earned since December 31, 1988 plus $60,000,000 (adjusted to remove the effect of any losses, write-offs or write-downs relating to the investment of any consolidated subsidiary in any generating station (not in commercial operation as of the date of the Note Agreement) as recorded on the consolidated books of account of the System as of December 31, 1988). The amount of the System's retained earnings available for cash dividends at December 31, 1993 was $85,187,000. Under the terms of the System's Declaration of Trust relating to Preferred Shares, dividends on Common Shares may not be paid nor may the System purchase any Common Shares until after dividends accrued on all outstanding Preferred Shares to the last preceding quarterly dividend payment date have been paid in full; nor may dividends be paid on the Common Shares when any required sinking fund redemption payment on the Preferred Shares is <PAGE 15> in arrears. No preferred dividends or required sinking fund redemption payments are in arrears. Voting Rights With the exception of certain specified voting rights of the Preferred Shares described herein, all voting rights of the System are vested in the holders of Common Shares and each Common Share is entitled to one vote. The holders of the Preferred Shares of all series, voting as a class, are entitled to elect two Trustees if and so long as six full quarterly dividends on any Preferred Shares shall have accrued and remain unpaid, the remaining seven Trustees to be elected by the holders of the Common Shares. In addition, the vote of the holders of at least two-thirds of the Preferred Shares of all series (or any series specially affected) is required as a condition to (i) altering the terms of the Preferred Shares in any manner substantially prejudicial to the holders thereof, and (ii) creating any class ranking prior to or on parity with the Preferred Shares in respect of either the payment of dividends or the distribution of assets. Without the vote of the holders of at least a majority of all Preferred Shares outstanding, the System may not (a) merge or consolidate with any other corporation or association unless the System is the successor, or otherwise sell or transfer its assets as, or substantially as, an entirety, or (b) issue any additional Preferred Shares or any class of shares ranking prior to or on a parity with the Preferred Shares unless, after giving effect to such issue, (i) consolidated net income of the System and its subsidiaries (after adding back interest charges on funded debt of the System) for any twelve consecutive months within the preceding fifteen months was one and one-half times the sum of annual interest charges on funded debt of the System plus the annual dividend requirements on Preferred Shares and on any class of shares ranking prior to or on a parity with the Preferred Shares and (ii) capital and paid-in premiums on outstanding Common Shares and any other shares ranking junior to the Preferred Shares, plus consolidated retained earnings of the System and its subsidiaries, are at least equal to capital and paid-in premiums represented by Preferred Shares and all other shares ranking prior to or on a parity with the Preferred Shares. Liquidation Rights On any liquidation of the System, the holders of Common Shares are entitled to share pro rata all assets after payment of debts and the liquidation preference plus accrued dividends of all series of Preferred Shares. Preemptive Rights Common shareholders have no preemptive rights in cases where additional Common Shares are issued otherwise than for cash, or offered for cash publicly by competitive bidding, or sold for cash to or through underwriters or investment bankers for public sale, or offered pursuant to a plan whereby holders may purchase Common Shares by either investing cash dividends from Common Shares or making optional cash payments, or to the issue of Common Shares where such shares are offered to the Employees Savings Plan of Commonwealth Energy System and Subsidiary Companies. If Common Shares are to be issued or sold for cash in any other manner, they must first be offered pro rata to the holders of the Common Shares at such price and on such terms and <PAGE 16> conditions and for such period as may be determined by the Trustees unless the holders of two-thirds of the outstanding Common Shares (or if treasury shares are to be resold for cash, a majority of the outstanding Common Shares) consent to some other disposition. Miscellaneous There are no sinking fund provisions and no rights of conversion or redemption applicable to the Common Shares. The outstanding Common Shares are, and the Common Shares offered hereby will be, when duly issued full-paid and nonassessable. The System is an unincorporated business trust with transferable shares. The System's Declaration of Trust provides that every person shall look only to the trust estate for payment of damages or otherwise and that all written agreements and obligations entered into by the System shall refer to this provision. The Declaration of Trust also states that the shares shall be full-paid and nonassessable, except as otherwise specifically provided in the certificates. Notwithstanding such provisions, the Supreme Judicial Court of Massachusetts has in some circumstances imposed personal partnership liability upon shareholders of an unincorporated business trust where the trust provides for ultimate control by shareholders. In the opinion of Michael P. Sullivan, Vice President, Secretary and General Counsel for the System, while a partnership may technically exist, the possibility of any such personal liability of the System's shareholders is remote because shareholders are pro- tected from personal liability on contract obligations containing the so- called limited liability clause which the System customarily inserts in all contract obligations, including debt securities, because the System is a holding company and not an operating company and the possibility of tort claims (which in any event except for fraud are adequately insured against) is therefore minimized, and because it has been the System's experience that its tax liabilities are adequately covered by its income. The Transfer Agent and Registrar for the Common Shares is The First National Bank of Boston, Boston, Massachusetts. LEGAL OPINIONS Legal matters in connection with this offering will be passed upon for the System by one or both of Messrs. Michael P. Sullivan, Vice President, Secretary and General Counsel and Richard J. Morrison, Assistant General Counsel and Assistant Secretary for the System, One Main Street, P.O. Box 9150, Cambridge, MA 02142-9150. As of September 1, 1994, Mr. Sullivan is the beneficial owner of 2,040 Common Shares of the System. EXPERTS The statements made as to matters of law and legal conclusions under the caption "Description of Common Shares" have been reviewed by Mr. Sullivan and are made on his authority as an expert. The consolidated financial statements and schedules of the System and subsidiaries included or incorporated by reference in the System's Annual Report on Form 10-K and incorporated by reference in this registration statement have been audited by Arthur Andersen LLP, independent public <PAGE 17> accountants, as indicated in their reports with respect thereto, and are included herein in reliance upon the authority of said firm as experts in accounting and auditing in giving said reports. INDEMNIFICATION Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable. __________________ The name "Commonwealth Energy System" means the trustees for the time being (as trustees but not individually) under a Declaration of Trust dated December 31, 1926, as amended, which is hereby referred to, and a copy of which has been filed with the Secretary of The Commonwealth of Massachusetts. Any agreement, obligation or liability made, entered into or incurred by or on behalf of said System binds only the trust estate, and no shareholder, director, trustee, officer or agent assumes, or shall be held to, any liability by reason thereof. <PAGE 18> __________________________________________ ______________________________ COM/Energy CONTENTS Commonwealth Energy System Page Available Information................ 3 DIVIDEND REINVESTMENT Incorporation of Certain Documents by Reference.......................... 3 and The System........................... 4 Use of Proceeds...................... 4 COMMON SHARE PURCHASE PLAN Description of the Plan.............. 4 Description of Common Shares......... 14 Legal Opinions....................... 16 Experts.............................. 16 Indemnification...................... 17 Common Shares of Beneficial Interest ($4 Par Value) September 23, 1994 PROSPECTUS __________________________________________ ______________________________ <PAGE 19> PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14.

Indemnification of Directors and Officers Each trustee, officer, agent or representative is entitled to reimbursement or indemnification against any and all loss, costs, expense and liability incurred or to be incurred by him in good faith in the execution of his duties. Each present and future trustee, officer, agent or representative is entitled to reimbursement or indemnification by the System for or against all expenses reasonably incurred or imposed by him in connection with, or arising out of, any action, suit or proceeding in which he may be involved by reason of his being or having been a trustee, officer, agent or representative of the System, where disposition of such action, suit or proceeding is made in favor of such trustee, officer, agent or representative; provided that no reimbursement shall be made until such time has elapsed that appeal can no longer be taken and that, in the judgement of the trustees, such action, suit or proceeding will not be recommended. No trustee, officer, agent or representative of the System shall be liable for any act, omission, step or conduct taken or had in good faith which is required, authorized or approved by any order or orders issued pursuant to the Public Utility Holding Company Act of 1935, the Federal Power Act or any state statute regulating the System or its subsidiaries. The provisions hereof shall be brought to the attention of any court and, if found by the court not to constitute a valid defense on the grounds of not being applicable to the particular class of plaintiff, each such trustee, officer, agent or representative shall be reimbursed for, or indemnified against, all expenses and liabilities incurred by him or imposed on him, in connection with, or arising out of, any such action, suit or proceeding based on any act, omission, step or conduct taken or had in good faith, and such expenses and liabilities shall include, but shall not be limited to, judgements, court costs and attorneys' fees. The foregoing rights shall not be exclusive of any other rights to which any trustee, officer, agent or representative might otherwise be entitled. <PAGE 20> The above is a summary of certain provisions of the System's Declaration of Trust, as amended, relating to indemnification of trustees and officers of the System. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.
