Sherman -------------------------------- Thomas W. Sherman Committee Member By /s/ William D. MacGillivray -------------------------------- William D. MacGillivray Committee Member By /s/ Elizabeth A. Foley -------------------------------- Elizabeth A. Foley Committee Member Date: June 30, 1998 -3- 4 INDEPENDENT AUDITORS' REPORT The Benefits Committee Bay State Gas Company We have audited the accompanying statements of Net Assets Available for Plan Benefits of the Bay State Gas Company Savings Plan for Operating Employees as of December 31, 1997 and 1996, and the related statements of Changes in Net Assets Available for Plan Benefits for each of the years in the three-year period ended December 31, 1997. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements 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 Plan Benefits of the Bay State Gas Company Savings Plan for Operating Employees at December 31, 1997 and 1996, and the changes in Net Assets Available for Plan Benefits for each of the years in the three-year period ended December 31, 1997 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. The fund information in the statements of changes in net assets available for plan benefits is presented for purposes of additional analysis rather than to present the changes in net assets available for plan benefits of each fund. The supplemental schedules of assets held for investment purposes and reportable transactions are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary 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 and supplemental schedules 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 is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Participants should refer to the Plan document for more complete information. (b) ELIGIBILITY All employees of the Company and its wholly-owned subsidiaries, Northern Utilities, Inc. and Granite State Gas Transmission, Inc. who are covered by a collective bargaining agreement between the Company and any union that specifically provides for participation in the Plan are eligible for participation. Participation begins in accordance with the terms of contracts negotiated with the various unions representing Company employees. Employees may participate in the Plan until death, retirement, or withdrawal of the entire contributed balance. 2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) BASIS OF PRESENTATION The accompanying financial statements have been prepared on the accrual basis of accounting. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Certain amounts of reported revenues and expenses are also affected by these estimates and assumptions. Actual results could differ from those estimates. -9- 10 BAY STATE GAS COMPANY SAVINGS PLAN FOR OPERATING EMPLOYEES Notes to Financial Statements December 31, 1997, 1996 and 1995 2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (b) INVESTMENTS Investments in the AIM Constellation Fund, MasterWorks S & P 500 Stock Fund, LifePath Funds, Company Stock Master Trust and the Templeton Foreign Fund are stated at market value. Market values are based on quotations from national securities exchanges for the various investments as of the close of business on the last day of the year. Guaranteed Investment Contracts ("GIC's") held by the Stable Value Fund are valued at contract value. Contract value represents contributions made under the contract plus interest at the contract rate. The crediting interest rates are fixed for GICs and averaged 7.18% at December 31, 1997. At December 31, 1997, the fair value of the GICs held by the Stable Value Fund approximates contract value. The Barclays Global Investors Income Accumulation Fund, held by the Stable Value Fund, is stated at market value which is based on the fair value of its underlying securities as follows: GICs and synthetic GICs, which are all benefit responsive, are stated at contract value, publicly traded U.S. Government notes and bonds are stated at quoted market value and money market securities are stated at cost which approximates fair value. Participant loans are valued at cost, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) in the fair value of investments includes both realized and unrealized gains and losses. -10- 11 BAY STATE GAS COMPANY SAVINGS PLAN FOR OPERATING EMPLOYEES Notes to Financial Statements December 31, 1997, 1996 and 1995 2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (c) PAYMENT OF BENEFITS Benefits are recorded when paid. 3) PLAN ADMINISTRATION (a) ADMINISTRATION The Plan is administered by the Bay State Gas Company Benefits Committee ("the Committee"), which is comprised of three or more individuals selected by the Board of Directors of the Company. The Committee carries out the provisions of the Plan, replies to questions, and resolves disputes arising under the Plan. Members of the Committee do not receive compensation for service. (b) EXPENSES The plan charges a monthly loan processing fee of $3.50 to participants borrowing from their accounts and a $10 fee for each participant's change of investment instructions in excess of 10 in any calendar year. 4) INVESTMENTS All contributions are remitted to the Plan Trustee for investment in accordance with the instructions of the participants. Participants may allocate their contributions (in 10% multiples) to various investment funds. Allocation percentages, as well as investment options among the investment funds, may be changed daily by the participant. The following investment funds are offered to active participants of the Plan. COMPANY STOCK MASTER TRUST - Funds are invested in the common stock of Bay State Gas Company. -11- 12 BAY STATE GAS COMPANY SAVINGS PLAN FOR OPERATING EMPLOYEES Notes to the Financial Statements December 31, 1997, 1996 and 1995 4) INVESTMENTS (CONTINUED) AIM CONSTELLATION FUND - Funds are invested principally in common stocks with emphasis on medium-sized and smaller emerging growth companies. TEMPLETON FOREIGN FUND - Funds are invested in stocks and debt obligations of companies and governments outside of the United States. MASTERWORKS S & P 500 STOCK FUND - Funds are invested in domestic debt and equity securities designed to approximate, as closely as practicable, the capitalization-weighted total rate of return of the S & P 500 Index. LIFEPATH FUNDS - Funds are invested in a changing mix of U.S. and international stocks, bonds and money market instruments. The target dates of each fund refers to the year when investors plan to retire or begin to withdraw portions of their investment. Each fund accepts higher risk early on, and adjusts its asset mix to lower-risk investments over time. STABLE VALUE FUND - Funds are invested in a combination of GICs and shares of the Barclays Global Investors Income Accumulation Fund. The Barclays Global Investors Income Accumulation Fund is a pooled stable value fund that invests in a variety of fixed-income securities including; GICs, synthetic GICs, publicly traded U.S. Government notes and bonds and money market securities. LOAN FUND - Funds are comprised of amounts borrowed by participants from their account balances (see Note 7). At December 31, 1997, each of the investment funds had the following number of participants: AIM Constellation Fund 229 LifePath 2000 Fund 16 LifePath 2010 Fund 48 LifePath 2020 Fund 49 LifePath 2030 Fund 50 LifePath 2040 Fund 65 Templeton Foreign Fund 271 S & P 500 Stock - MasterWorks Fund 266 Stable Value Fund 232 Company Stock Master Trust 354 -12- 13 BAY STATE GAS COMPANY SAVINGS PLAN FOR OPERATING EMPLOYEES Notes to the Financial Statements December 31, 1997, 1996 and 1995 4) INVESTMENTS (CONTINUED) All funds, with the exception of the Loan Fund and the LifePath Funds, represented more than five percent of Net Assets Available for Plan Benefits at December 31, 1997 and 1996. 5) INTEREST IN BAY STATE GAS COMPANY STOCK MASTER TRUST A portion of the Plan's investments are invested in the Company Stock Master Trust (Master Trust) which was established for the investment of assets of the Plan and the Bay State Gas Company Employee Savings Plan. Each plan has an undivided interest in the Master Trust. The assets of the Master Trust are held by Barclays Global Investors. At December 31, 1997 and 1996, the Plan's interest in the net assets of the Master Trust was approximately 31% and 26%, respectively. Investment income and administrative expenses relating to the Master Trust are allocated to the individual plans based upon average monthly balances invested by each plan. Contributions and benefit payments to Plan participants directly increase/decrease the assets of the Master Trust allocated to the Plan. The following table presents the fair values of investments for the Master Trust.
