INDEPENDENT AUDITORS' REPORT

To the Administrative Committee of the
Northern Indiana Public Service Company
Bargaining Unit Tax Deferred Savings Plan
Merrillville, Indiana

We have audited the accompanying statements of net assets available for benefits
of the Northern Indiana Public Service Company Bargaining Unit Tax Deferred
Savings Plan (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.

NORTHERN INDIANA PUBLIC SERVICE COMPANY
BARGAINING UNIT TAX DEFERRED SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 2002 AND 2001
- --------------------------------------------------------------------------------


1.    DESCRIPTION OF PLAN

      Northern Indiana Public Service Company (the "Company") is a wholly owned
      subsidiary of NiSource Inc. The following description of the Northern
      Indiana Public Service Company Bargaining Unit Tax Deferred Savings Plan
      ("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 October 1, 1987. It is a
      defined contribution plan available to substantially all active bargaining
      unit employees of the Company. 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. 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 50% of
      compensation (as defined in the Plan) on a pre-tax basis and 25% on an
      after-tax basis, up to 75% in total. 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 contributes an amount equal to 1/9th of a participant's
      pre-tax contribution that is invested in NiSource Inc. Common Stock Fund.
      Employees, age 50 and older, may direct matching NiSource Inc. Common
      Stock Funds among any of the funds available in the Plan.

      ROLLOVERS FROM OTHER QUALIFIED EMPLOYER PLANS--The Plan allows for
      employees to transfer certain of their other qualified employer retirement
      plan assets to the Plan. These amounts are reflected in participant
      contributions in the accompanying statement of changes in net assets
      available for benefits.

      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 prime rate plus 1% based on
      the last day of the previous month they take out the loan. Principal and
      interest are paid ratably through payroll deductions over a period not to
      exceed five years, unless the loan is to purchase the participant's
      primary residence, which allows repayment up to 15 years.


                                     - 4 -






      PAYMENT OF BENEFITS--All amounts distributed from a participant's account
      following termination of employment shall be distributed in one lump sum
      amount, in cash, or, if elected by the participant or beneficiary, in
      shares of NiSource Inc. common stock based on the numbers of whole shares
      allocated to the NiSource Inc. Common Stock Fund for the participant. 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 AND TENDERING 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) or tendering shares during a tender offer, represented
      by the value of the participant's interest in the NiSource Inc. Common
      Stock Fund.

      RECLASSIFICATIONS--Certain amounts in the 2001 financial statements have
      been reclassified to conform with the 2002 presentation.

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. 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 and broker fees are paid by the Plan.

                                                                               $(13,811,061)

      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.

           * Includes participant-directed investments


5.    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.

6.    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.

7.    TAX STATUS

      The Internal Revenue Service (the "IRS") has determined and informed the
      Company by a letter dated January 28, 1997, 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. The Plan administrator submitted a letter to the
      IRS, dated February 28, 2002, requesting a new determination.
