These financial statements and the supplemental schedules referred to below are the responsibility of the plan administrator. Our responsibility is to express an opinion on these financial statements and supplemental schedules based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Employees Savings Plan of Commonwealth Energy System and Subsidiary Companies as of December 31, 1996 and 1995, and its changes in net assets available for benefits for each of the three years in the period ended December 31, 1996, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. Supplemental Schedules I and II are presented for purposes of additional analysis and are not a required part of the basic financial statements, but are supplemental information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The Fund Information in the statement of net assets available for benefits and the statement of changes in net assets available for benefits is presented for purposes of additional analysis rather than to present the net assets available for benefits and changes in net assets available for benefits of each fund. The supplemental schedules and Fund Information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

The Plan has been amended or restated from time to time thereafter. The latest Plan amendment was made as of January 1, 1997. Since January 1, 1989, Vanguard Fiduciary Trust Company of Valley Forge, Pennsylvania, has acted as Trustee for the Plan (Plan Trustee). The Trustee retains the Plan assets and provides records of Plan activity to a Plan Agent designated by a three-member Savings Plan Board (the Board) that is appointed by the Trustees of the System and by the directors of its subsidiary companies. The Board is responsible (except for the duties specifically vested in the Plan Trustee) for the administration of the Plan. The term "Participant" shall be deemed to include Members, Inactive Members or Former Members, all as defined in the Plan. The Employers participating in the Plan consist of certain subsidiary companies of Commonwealth Energy System, as follows: Cambridge Electric Light Company, Canal Electric Company, Commonwealth Gas Company, COM/Energy Services Company and Commonwealth Electric Company (Employers). The Employers are wholly-owned by the System. Each eligible employee, upon joining the Plan, shall specify in 1% increments his or her contributions and the applicable Employer contributions to be invested in each of twelve separate Investment Funds (Fund(s)) that are collectively referred to as the Trust Fund (Trust Fund). Effective April 1, 1996, five additional Investment Funds were made available to Participants. These Funds include the Vanguard Explorer Fund and the four Vanguard LIFEStrategy Funds which are designed to match the objectives and risk tolerances of a Participant's various life stages. These and the Plan's other Funds are further described in Note 4. Participants may change their Fund allocation contribution daily by contacting Vanguard Participant Services. However, not more than 50% of a Participant's contributions and the applicable Employer contributions may be allocated to the System's Common Share Fund. The Plan is subject to provisions of the Employee Retirement Income Security Act of 1974 (ERISA), the Retirement Equity Act of 1984, the Tax Reform Act of 1986 and the Omnibus Budget Reconciliation Act of 1993 relating to plans of this type. The number of shares of Commonwealth Energy System Common Share Fund purchased, sold or distributed and held by the Plan at December 31, have been restated for 1995 and 1994 to reflect a two-for-one stock split that became effective June 5, 1996. <PAGE 25> EMPLOYEES SAVINGS PLAN OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES NOTES TO FINANCIAL STATEMENTS (2) Significant Accounting Policies (a) Principles of Accounting The Plan Trustee's records are maintained on a cash basis. The accompanying financial statements include all adjustments necessary to present the statements on an accrual basis of accounting. Quoted market prices are used to value the System's Common Share Fund and the Vanguard Funds. In addition, certain prior period amounts are reclassified from time to time to conform with the presentation used in the current year's financial statements. (b) Federal Income Taxes The Plan is subject to certain provisions of the Internal Revenue Code (IRC) and qualifies under Section 401(a) and 401(k) of the Code. The Internal Revenue Service (IRS) has issued a favorable determination letter, applicable to Plan years beginning after January 1, 1993 and for amendments adopted on January 15, 1993, which indicates that the Plan was designed in accordance with applicable IRC requirements. Management believes that the Plan is currently designed and operated in accordance with applicable IRC requirements. As a result, the Plan has not provided for Federal income taxes. Generally, Participants are not subject to taxes on contributions or the earned income until such time as distributions are made. (c) Expenses Brokerage fees, commissions, stock transfer taxes and other expenses in connection with the purchase, sale or distribution of securities for each investment fund may be charged to such fund. Any expense of litigation may be paid by the Plan Trustee and charged to the Trust Fund or to the Investment Fund or Funds to which the litigation relates. Expenses and charges incurred in the administration of the Plan are generally paid by the Employers. An administrative fee relating to the issuance of Plan loans under the Loan Fund is paid by Plan Participants. (d) Realized Gain (Loss) on Investments Sold or Distributed Pursuant to rules issued by the Department of Labor (DOL), realized gain (loss) was computed by comparing the market value of the securities distributed or sold with the market value of said securities at the beginning of the Plan year. The System's Common Share Fund realized gains (losses) of $675,475, $1,027,097 and ($545,138) on the distribution or sale of 453,158, 414,822 and 195,734 System Common Shares in 1996, 1995 and 1994, respectively. <PAGE 26> EMPLOYEES SAVINGS PLAN OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES NOTES TO FINANCIAL STATEMENTS A summary of realized gains (losses) on securities sold or distributed during the years ended December 31, 1996, 1995 and 1994 is set forth below: Quoted Quoted Market Price Market Price Beginning of Gain Investment Funds or Proceeds Year (Loss) 1996 Commonwealth Energy System Common Share Fund $10,814,896 $10,139,421 $ 675,475 Vanguard Money Market Reserves- Prime Portfolio 17,818,107 17,818,107 - Vanguard Windsor II Fund 12,205,764 11,313,017 892,747 Vanguard Fixed Income Securities Fund- Short-Term Corporate Portfolio 2,170,370 2,196,757 (26,387) Vanguard Wellington Fund 6,174,856 5,962,417 212,439 Vanguard International Growth Portfolio 3,791,405 3,632,606 158,799 Vanguard Index Trust- Extended Market Portfolio 1,433,320 1,371,491 61,829 Vanguard Explorer Fund (1) 1,210,006 1,220,007 (10,001) Vanguard LIFEStrategy Funds (1)(2) 116,672 114,869 1,803 $55,735,396 $53,768,692 $1,966,704 1995 Commonwealth Energy System Common Share Fund $ 8,320,160 $ 7,293,063 $1,027,097 Vanguard Money Market Reserves- Prime Portfolio 13,863,305 13,863,305 - Vanguard Windsor II Fund 8,895,459 7,758,707 1,136,752 Vanguard Fixed Income Securities Fund- Short-Term Corporate Portfolio 1,708,442 1,664,677 43,765 Vanguard Wellington Fund 4,213,461 3,690,865 522,596 Vanguard International Growth Portfolio 3,897,722 3,816,016 81,706 Vanguard Index Trust- Extended Market Portfolio 450,953 412,569 38,384 $41,349,502 $38,499,202 $2,850,300 1994 Commonwealth Energy System Common Share Fund $ 3,981,245 $ 4,526,383 $ (545,138) Vanguard Money Market Reserves- Prime Portfolio 8,709,357 8,709,357 - Vanguard Windsor II Fund 6,529,551 6,624,955 (95,404) Vanguard Fixed Income Securities Fund- Short-Term Corporate Portfolio 2,231,660 2,287,937 (56,277) Vanguard Wellington Fund 4,428,748 4,544,012 (115,264) Vanguard International Growth Portfolio 1,382,971 1,368,400 14,571 Vanguard Index Trust- Extended Market Portfolio 221,842 225,328 (3,486) $27,485,374 $28,286,372 $ (800,998) (1) Available to Participants since April 1, 1996 (2) Consists of four portfolios - Income, Conservative Growth, Moderate Growth, and Growth <PAGE 27> EMPLOYEES SAVINGS PLAN OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES NOTES TO FINANCIAL STATEMENTS (e) Unrealized Appreciation (Depreciation) of Investments The Plan provides that the market value of each Investment Fund shall be determined by the Trustee each quarter. Pursuant to the rules issued by the DOL, unrealized appreciation (depreciation) shall equal the difference between market value at the beginning of the Plan year and the quoted market price of the investments at the applicable valuation date in determining the value of each fund.

The allocation of each Fund's earnings to a Participant's account is based on the percent of the Participant's units in the Funds and is allocated daily. (3) Participating Companies and Contributions Employees are eligible to join the Plan upon completion of one-thousand (1,000) hours of service in a twelve-month period and are fully vested upon Plan entry. Generally, Participants in the Plan are required to make contributions of at least 1% but not more than 16% of their compensation as defined in the Plan. However, the maximum amount a Participant may defer annually is $9,500 currently (as increased from time to time by the Secretary of the Treasury in accordance with the cost of living adjustment factor prescribed in Section 402(g)(1) of the IRC). Compensation is defined to be an employee's authorized basic salary (including any "lump sum payment" under the authorized basic compensation pay program), except that in the case of sales personnel compensated in whole or in part by commissions, compensation shall be considered to equal 90% of the average compensation earned by such employee in the preceding four calendar quarters but not less than each employee's authorized basic compensation. Salary deferral contributions by employees are made to the Plan by payroll deduction. The Employer contributes an additional amount equal to each employee's contribution, up to a maximum of four percent of each employee's basic compensation rate, as previously defined, and up to five percent for those employees no longer eligible for postretirement health benefits. Effective January 1, 1997, any eligible employee may change his or her contribution percentage as of the first day of any month by contacting Vanguard Participant Services by the 15th day of the preceding month. Previously, as of April 1, 1996, changes to the contribution percentage were only permitted quarterly as of January 1, April 1, July 1 or October 1 in each calendar year (but not retroactively), at least thirty (30) days prior to the beginning of any quarter. <PAGE 29> EMPLOYEES SAVINGS PLAN OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES NOTES TO FINANCIAL STATEMENTS The participating system companies and contributions for the years ended December 31, 1996, 1995 and 1994 are summarized below: Employee Contributions 1996 1995 1994 Cambridge Electric Light Company $ 658,553 $ 654,474 $ 688,568 Canal Electric Company 684,476 642,435 609,812 Commonwealth Electric Company 3,814,155 3,687,316 3,482,617 Commonwealth Gas Company 2,134,806 2,749,403 2,759,444 COM/Energy Services Company 1,002,899 945,449 876,966 $8,294,889 $8,679,077 $8,417,407 Employer Contributions 1996 1995 1994 Cambridge Electric Light Company $ 310,388 $ 317,289 $ 325,109 Canal Electric Company 260,990 258,375 249,749 Commonwealth Electric Company 1,788,366 1,813,432 1,745,722 Commonwealth Gas Company 1,108,006 1,439,253 1,447,005 COM/Energy Services Company 585,299 564,381 534,442 $4,053,049 $4,392,730 $4,302,027 Participation by employees is voluntary and, effective January 1, 1997, may begin as of the first day of any month by notifying the respective employer in writing on or before the fifteenth day of the preceding month coincident with or next following eligibility. Previously, salary deferral changes were only permitted on a quarterly basis. Of the 2,090 current eligible employees as of December 31, 1996, 2,055 (98.3%) members were participating in the Plan. (4) Investments (a) Investment Funds Descriptions The following is a description of the twelve Investment Funds in which a Participant may allocate his or her contributions and matching Employer contributions: Common Shares of Commonwealth Energy System - Consists of Common Shares of Beneficial Interest of Commonwealth Energy System purchased on the open market or through the System's Dividend Reinvestment and Common Share Purchase Plan. The System's Common Shares may also be acquired directly from the System, if such Common Shares are made available by the Board of Trustees of the System, based on the fair market value at the time of acquisition. The Common Shares are acquired with employee contributions and Employer contributions, dividends and interest income. The Trustee, at its discretion, will determine the manner in which such shares may be acquired. Vanguard Money Market Reserves-Prime Portfolio - A mutual fund that seeks the maximum current income that is consistent with preservation of capital and <PAGE 30> EMPLOYEES SAVINGS PLAN OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES NOTES TO FINANCIAL STATEMENTS liquidity. Value is added primarily by emphasizing specific issues and sectors of the money market that appear to be attractively priced based upon historical yield spread relationships. Average maturity for the Fund is normally maintained in the range of 30-70 days, and the Fund can own no security with a maturity longer than one year. Such money market instruments include domestic certificates of deposit and bankers' acceptances, commercial paper, U.S. Treasury and Government agency securities and repurchase agreements on such securities and up to 50% of net assets can be invested in Eurodollar certificates of deposit issued by approved U.S. banks. Vanguard Windsor II - A mutual fund having a primary objective to provide long-term growth of capital and income. As a secondary objective, the Fund seeks a reasonable level of current income. The Fund is a value-oriented growth and income fund seeking investment opportunities primarily in common stocks that are out of favor or undervalued. Vanguard Fixed Income Securities Fund-Short-Term Corporate Portfolio - A mutual fund which seeks to provide a high level of current income consistent with a two to three-year average maturity. By investing in relatively short maturity investment-grade bonds, the Portfolio is designed to help preserve capital. Vanguard Wellington Fund - A mutual fund designed to pursue conservation of capital, reasonable current income and profits without undue risk. Conservatively structured, the Fund uses a balanced investment approach allocating 60%-70% of net assets to equities and the remainder to fixed income securities. The fixed income securities reduce the Fund's exposure to risks of common stocks while common stocks are selected from dividend-paying medium and large-capitalization stocks whose prospects are improving. The objective is to identify these companies before their values are recognized in the marketplace. Vanguard International Growth Portfolio - A mutual fund which seeks long- term capital growth by investing in capital stocks of companies based outside the United States that have above-average growth potential. Vanguard Index Trust-Extended Market Portfolio - A mutual fund that attempts to duplicate the investment results of the broad universe of publicly traded United States stocks not included in the Standard & Poor's 500 Composite Stock Price Index. The Extended Market Portfolio is a market- capitalization-weighted "benchmark portfolio" consisting of more than 4,500 regularly traded stocks that are represented by the Wilshire 4500 Index. The Portfolio will invest in a sample of stocks in the benchmark portfolio selected on the basis of market capitalization, industry weightings and fundamental investment characteristics.

(b) Investment Funds Accounts The Savings Plan Board maintains for each Participant in the Plan, under each Fund in which all or part of his or her contributions and the applicable Employer contributions are invested, a separate Member Account that includes a Pay Deferral Account for current pre-tax contributions. In addition, the Member Account may include previous after-tax contributions. The Savings Plan Board also maintains a separate Company Account (for each Participant) that includes Employer contributions made on behalf of Participants. These Accounts reflect the portion of each Participant's interest in the Investment Fund which is attributable to the contributions to such Accounts. The Plan permits Participants to transfer amounts between Funds on a daily basis, subject to certain limitations. The Plan Trustee may, at its discretion, temporarily invest funds designated for a particular Fund in short-term interest-bearing securities or may retain certain amounts of cash in each Fund without interest being credited thereon, for the purpose of more effectively timing the purchase of investments or liquidity needs for the several Funds. All contributions are transmitted weekly to the Plan Trustee. A Participant's choice of contribution allocation to eligible Funds will continue until changed by such Participant. Investment designations may be changed once a day by contacting a Vanguard Participant Services representative. All interest, dividends, and other income, as well as any cash from the sale or exchange of securities or other property produced by each of the Funds will be reinvested in the same Fund which produced such interest, dividends and other income.
