INDEPENDENT AUDITORS' REPORT To the Administrative Committee of the Bay State Gas Company Savings Plan For Operating Employees and Trust Merrillville, Indiana We have audited the accompanying statements of net assets available for benefits of the Bay State Gas Company Savings Plan for Operating Employees and Trust (the "Plan") as of December 31, 2002 and 2001, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002. 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 auditing standards generally accepted in the United States of America. 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, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2002 and 2001, and the changes in net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule listed in the Table of Contents is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is 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. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 2002 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic 2002 financial statements taken as a whole.

DESCRIPTION OF THE PLAN Bay State Gas Company (the "Company") is a wholly owned subsidiary of NiSource Inc. The following description of the Bay State Gas Company Savings Plan for Operating Employees and Trust (the "Plan") provides general information regarding the Plan. Participants should refer to the Plan document for a more complete description of the Plan's provisions. GENERAL--The Plan was established effective January 1, 1988. It is a defined contribution plan available to substantially all employees of the Company who are covered by a collective bargaining agreement between the Company and any union that specifically provides for participation in the Plan. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. PLAN ADMINISTRATION--The Company serves as administrator and sponsor of the Plan. NiSource Inc. maintains an administrative committee appointed by the Board of Directors, which has the responsibility to assist the Company in administering the Plan. Merrill Lynch Trust Company held the Plan's assets and executed all investment transactions through December 31, 2001. Effective January 1, 2002, Fidelity Management Trust Company (the "Trustee") holds all of the Plan's assets and executes all investment transactions. CONTRIBUTIONS--Each year, participants may contribute up to 15% of compensation (as defined in the Plan) on a pre-tax basis. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Contributions are subject to certain limitations. Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan currently offers twenty-seven mutual funds, one money market fund and one common stock fund as investment options for participants. The Company makes contributions to the Plan in accordance with the various governing collective bargaining agreements as set forth in the Plan document. For certain employees, the Company makes no contribution. For other employees, the Company makes contributions from 2.5% to 3.5% of eligible compensation. The matching Company contribution is allocated according to the participants' directed accounts. PARTICIPANT ACCOUNTS--Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) Plan earnings, and charged with an allocation of certain administrative expenses. VESTING--Participants are fully vested in their accounts at all times. PARTICIPANT LOANS--Participants that have participated in the Plan for at least one year may borrow up to 50% from their accounts a minimum of $1,000 up to a maximum of $50,000. The loans are secured by the balance in the participant's account and bear interest at rates that range from 4.75% to 10.5%, which are commensurate with local prevailing rates as determined by the provisions of the Plan and subject to periodic review by the administrative committee. Principal and interest are paid ratably through payroll deductions over a period not to exceed five years, unless the loan is used to purchase the participant's primary residence, which allows repayment up to 15 years. -4- PAYMENT OF BENEFITS--On termination of service due to death, disability, retirement or other reasons, a participant may elect to receive a distribution in (1) a single lump sum; (2) a portion paid in a lump sum, and the remainder paid later (partial payment); or (3) periodic installments over a period not to exceed the life expectancy of the participant and his or her beneficiary. Participants may elect that a distribution in the form of a lump sum payment be made in the form of whole shares of NiSource Inc. stock and cash in lieu of fractional shares (to the extent the distribution consists of amounts from the NiSource Inc. Common Stock Fund). If the amount payable under the Plan to any participant or beneficiary is less than or equal to $5,000, the committee will direct that such amount be paid in a lump sum. TRANSFERS BETWEEN PLANS--Transfers between plans occur when employees transfer out of the Union but stay with NiSource Inc., which results in a transfer of any related balances between this Plan and other plans. Amounts are included in transfers, net on the accompanying statement of changes in net assets available for benefits. EMPLOYEE STOCK OWNERSHIP PLAN--Effective January 1, 2002, the NiSource Inc. Common Stock Fund was changed to operate as an Employee Stock Ownership Plan (ESOP). As an ESOP, under the terms of this plan, participants may diversify their investment attributable to employer match at any time after they reach age 50. Participants may also elect to have dividends paid to them in cash or reinvested in the fund. VOTING RIGHTS OF NISOURCE INC. COMMON STOCK FUND PARTICIPANTS--Each participant in the NiSource Inc. Common Stock Fund is entitled to direct the Trustee as to the manner of voting at each meeting of shareholders, all shares of NiSource Inc. common stock (including fractional shares), represented by the value of the participant's interest in the NiSource Inc. Common Stock Fund. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING--The financial statements of the Plan were prepared using the accrual basis of accounting. USE OF ESTIMATES--The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. INVESTMENT VALUATION AND INCOME RECOGNITION--The Plan's investments are stated at fair value. Participant loans are valued at cost, which approximates fair value. Quoted market prices are used to value investments. Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the record date. PAYMENT OF BENEFITS--Benefits are recorded when paid. ADMINISTRATIVE EXPENSES--Most administrative expenses of the Plan are paid by the Company. Certain other expenses of the Plan such as investment manager fees and broker fees are paid by the Plan. -5- 3. INVESTMENTS The following presents investments that represent 5% or more of the Plan's net assets. December 31, ------------------------------------- 2002 2001 NiSource Inc. Common Stock Fund $ 4,826,318 Fidelity Growth Fund 2,126,693 Fidelity Overseas Fund 1,588,822 Fidelity Retirement Money Market Fund 3,657,011 Fidelity Spartan U.S. Equity Fund 3,983,272 Interest bearing cash $ 23,986,691 During 2002, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) depreciated in value as follows: Mutual funds $ (3,515,388) NiSource Inc. Common Stock Fund (841,894) ------------ $ (4,357,282) ============ The Plan provides for investments in mutual funds and common stock that, in general, are exposed to various risks, such as interest rate, credit and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the accompanying statements of net assets available for benefits. 4. RELATED-PARTY TRANSACTIONS The Plan invests in NiSource Inc. common stock. Since NiSource Inc. is the parent of the Company, any investment transactions involving NiSource Inc. common stock qualify as party-in-interest transactions. Additionally, certain Plan investments are shares of mutual funds managed by the Fidelity Management Trust Company. Fidelity Management Trust Company is the Trustee, as defined by the Plan and therefore, these transactions qualify as party-in-interest transactions. 5. PLAN TERMINATION Although it has not expressed any intention to do so, the Company reserves the right under the Plan document to terminate the Plan at any time, subject to the provisions of ERISA. In the event of Plan termination, the rights of each participant to all amounts then credited to his or her account will continue to be nonforfeitable. 6. TAX STATUS The Internal Revenue Service (the "IRS") has determined and informed the Company by a letter dated January 17, 2001, that the Plan is designed in accordance with applicable sections of the Internal Revenue Code (the "IRC"). Although the Plan has been amended since receiving the determination letter, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. ****** -6- SUPPLEMENTAL SCHEDULE BAY STATE GAS COMPANY SAVINGS PLAN FOR OPERATING EMPLOYEES AND TRUST EIN: 04-3442797, PLAN NUMBER 011 SCHEDULE H, LINE 4I - SCHEDULE OF ASSETS (HELD AT END OF YEAR) AS OF DECEMBER 31, 2002 IDENTITY OF ISSUER, DESCRIPTION OF INVESTMENT, BORROWER, LESSOR, INCLUDING MATURITY DATE, RATE OF INTEREST, FAIR OR SIMILAR PARTY COLLATERAL AND PAR OR MATURITY VALUE VALUE * NiSource Inc.
