        New NiSource Inc. (the "Company") and NiSource Inc. ("Old

                                 THE COMPANY

        On November __, 2000, New NiSource Inc. (the "Company"), a new
   company formed by NiSource Inc. ("NiSource"), completed the
   acquisition by merger of Columbia Energy Group ("Columbia").
   Effective November __, 2000, the Company changed its name to "NiSource
   Inc."  Upon completion of the merger, Columbia became a wholly-owned
   subsidiary of the Company, and the Company continues the businesses
   conducted by NiSource and Columbia prior to the merger.  The fiscal
   year of the Company will end on December 31 of each year.  The Company
   is a Delaware corporation with its corporate headquarters in
   Merrillville, Indiana.

        The Company is a super-regional energy and utility-based holding
   company that provides natural gas, electricity, water and energy
   related services for residential, commercial and industrial uses
   through a number of regulated and non-regulated subsidiaries.  The
   Company has over 3.6 million gas and  electric customers located
   primarily in nine states and is the leading gas competitor within the
   key energy corridor between the Gulf Coast and the Northeast. The
   Company is a registered holding company under the Public Utility

   offices are located at 801 East 86th Avenue, Merrillville, Indiana

        NATURAL GAS.  The Company's gas business is comprised of

   nine states.  The Company is the largest gas company east of the
   Rockies based on customers, and has the nation's second largest volume
   of gas sales with 911 million cubic feet per day.

        Through its wholly-owned subsidiary, Columbia Energy Group, the
   Company owns five distribution subsidiaries that provide natural gas
   services to nearly 2.1 million residential commercial and industrial
   customers in Ohio, Pennsylvania, Virginia, Kentucky and Maryland.  The
   Company also distributes natural gas to approximately 751,000

                                      4

   Inc. distribute natural gas to more than 320,000 customers in the
   areas of Brockton, Lawrence and Springfield, Massachusetts, Lewiston
   and Portland, Maine, and Portsmouth, New Hampshire.

        The Company's subsidiaries Columbia Gas Transmission Corporation
   and Columbia Gulf Transmission Company own and operate an interstate
   pipeline network of approximately 16,250 miles extending from offshore
   in the Gulf of Mexico to Lake Erie, New York and the eastern seaboard.
   Together, Columbia Gas Transmission and Columbia Gulf serve customers
   in 15 northeastern, mid-Atlantic, midwestern, and southern states and
   the District of Columbia.  In addition, Columbia Gas Transmission
   operates one of the nation's largest underground natural gas storage
   systems. Columbia Gas Transmission is also participating in the
   proposed 442-mile Millennium Pipeline Project that has been submitted
   to the FERC for approval.  As proposed, the project will transport
   approximately 700,000 Mcf of natural gas per day from the Lake Erie
   region to eastern markets.

        The Company's wholly-owned subsidiary, Crossroads Pipeline
   Company, owns and operates a 201-mile, 20 inch diameter interstate
   pipeline extending from the northwestern corner of Indiana (near the
   border with Chicago) eastward into Ohio.  Another wholly-owned Company
   subsidiary, Granite State Transmission, owns and operates a 105-mile,
   6 to 12 inch diameter interstate pipeline that extends from Haverhill,
   Massachusetts in a northeasterly direction to Maine.  In addition to
   the Crossroads and Granite State pipelines, the Company owns a 19%
   share of Portland Natural Gas Transmission System, a 292-mile pipeline
   built to bring Canadian gas from New Brunswick into Maine, New
   Hampshire and Massachusetts in order to increase the gas supply to the
   region.

        ELECTRICITY.  The Company generates and distributes electricity
   to the public through its subsidiary Northern Indiana Public Service

   unregulated power projects through its subsidiary, Primary Energy,
   Inc.  Primary Energy works with industrial customers in managing the
   engineering, construction, operation and maintenance of "inside the
   fence" cogeneration plants that provide cost-effective, long-term

        NON-REGULATED ENERGY SERVICES.  The Company provides non-
   regulated energy services through its wholly-owned subsidiary Energy
   USA, Inc.  Through its subsidiaries and investments, Energy USA
   provides to customers in 22 states a variety of energy-related
   services, including gas marketing and asset management services,
   pipeline construction and underground utility locating and marking
   services.  The Company expanded its gas marketing and trading
   operations with the April 1999 acquisition of TPC Corporation,
   now renamed Energy USA-TPC Corp., a natural gas asset management
   company.  Through Columbia, it also owns Columbia Energy Resources,
   Inc., an exploration and production subsidiary that explores for,
   develops, gathers and produces natural gas and oil in Appalachia
   and Canada.  In addition, the Company has invested in a number of
   distributed generation technologies, including fuel cells and
   microturbine ventures.

        In the merger, NiSource shareholders received one common share of
   the Company, par value $.01 per share, ("Common Share") for each of
   their NiSource common shares.  Accordingly, each of the NiSource
   common shares held in the NiSource Common Stock Fund under the Plan
   has been converted into one Common Share of the Company.

   MERGER

        On November __, 2000, New NiSource Inc. (the "Company"), a new
   company formed by  NiSource Inc. ("NiSource") completed the
   acquisition by merger of Columbia Energy Group ("Columbia").
   Effective November __, 2000, the Company changed its name to "NiSource
   Inc."  Upon completion of the merger, Columbia became a wholly-owned
   subsidiary of the Company, and the Company continues the businesses
   conducted by NiSource and Columbia prior to the merger.  The fiscal
   year of the Company will end on December 31 of each year.  The Company
   is a Delaware corporation with its corporate headquarters in
   Merrillville, Indiana.  All references in the Plan and the Summary
   Plan Description to NiSource common shares are now references to
   common shares of the Company, par value $.01 per share ("Common
   Shares").  Except as described below, all of the terms of the Plan
   will continue to apply.

        In the merger, each NiSource common share was converted into the
   right to receive one  Common Share of the Company.  Accordingly, each
   NiSource common share held in the NiSource Common Stock Fund under the
   Plan has been converted into one Company Common Share.

   PLAN HIGHLIGHTS

   Saving for your future is a challenge, but with the Bay State Gas
   Company Savings Plan for Operating Employees saving can be both
   convenient and profitable. The Plan offers you these advantages:

        *    You choose how much to save, up to 15% of your eligible pay
             through convenient payroll deduction.

        *    You may save on taxes since contributions and earnings are
             not subject to current federal and, in most cases, state
             income taxes.

   The Plan offers you flexibility:

        *    You choose how to invest your Account among the investment
             funds offered.

             You may borrow or withdraw from your Account (subject to
             certain conditions and terms).

        *    You have easy access to Account information by telephone.

   The Plan is a profit-sharing 401(k) plan designed to help you
   accumulate savings for retirement and achieve your future financial
   goals. It is one of the few ways you can set aside savings for the
   future without having to pay current federal and, in most cases, state
   income taxes on the money you are saving and the earnings from the
   investments in your Account.

   been processed. If you discontinue contributions more than once in a
   12-month period, the Administrator reserves the right to require a
   longer waiting period before you resume contributions.

   To begin or change your contribution percentage election or to
   discontinue or resume contributions, refer to Section entitled
   INSTRUCTIONS AT A GLANCE.

   ROLLOVER CONTRIBUTIONS FROM ANOTHER QUALIFIED PLAN

   If you receive a distribution eligible for rollover from another
   employer's qualified plan (or a qualified plan of Bay State) or if you
   have a "rollover IRA," you may "roll over" all or part of that amount
   into this Plan if you are an eligible employee, even if you have not
   yet met the Plan's eligibility requirements. By making a Rollover
   contribution, you defer the tax liability on your distribution and
   take advantage of the investments offered in this Plan.

   Your Rollover contributions are deposited into your Rollover Account.

   To make a Rollover contribution, refer to Section entitled
   INSTRUCTIONS AT A GLANCE.

   SEPARATE ACCOUNTS

   Separate Accounts will be maintained for your contributions as
   described above and may also include a Prior After-Tax Account for
   after-tax contributions made under former Plan provisions.

   EMPLOYER CONTRIBUTIONS

   EMPLOYER CONTRIBUTIONS

   Your eligibility for Employer contributions and the amount Bay State
   contributes are determined under the terms of your governing
   collective bargaining agreement. If your collective bargaining
   agreement calls for Employer contributions, the Employer contributions

                                      15







   are based on your Employee Pre-Tax contributions and are deposited to
   your Account each time you contribute.

   Employer contributions made on your behalf are deposited into your
   Employer Account.

   SEPARATE ACCOUNTS

   Separate Accounts will be maintained for your Employer contributions
   as described above and which may also include a Prior Company Account
   for contributions made under former Plan provisions.

   ANNUAL CONTRIBUTION AND COMPENSATION MAXIMUMS

   The Internal Revenue Code and related regulations require that a
   number of limitations be applied to the Plan. These include (1)
   maximum amounts which may be contributed by you or on your behalf in
   any year and (2) a maximum amount of your eligible pay that may be
   taken into account for purposes of contributions. These limitations
   are briefly described below:

   MAXIMUM PRE-TAX CONTRIBUTION DOLLAR LIMIT.

   Your maximum pre-tax contribution dollar limit (including any pre-tax
   contributions you may make to any other 401(k) plan) is established
   each calendar year. This limit may be adjusted annually as announced
   by the Internal Revenue Service. For the calendar years 1998 and 1999,
   this limit is $10,000.  For the calendar year 2000, this limit is
   $10,500.

   If you make pre-tax contributions to more than one 401(k) plan during
   the calendar year and the combination of your pre-tax contributions to
   the plans exceeds the maximum pre-tax contribution dollar limit, you
   should notify the Plan Administrator of this Plan or the plan
   administrator of the other plan that an excess has occurred and
   request that the excess amount be returned to you no later than April
   15 of the following year. If the excess amount is not returned to you
   by April 15 of the following year, the excess amount will be taxable
   to you in the year the amount was contributed and the year the amount
   is distributed.

   MAXIMUM ALLOWABLE CONTRIBUTION PERCENTAGE LIMIT.

   If you are a highly compensated employee, your maximum Employee Pre-
   Tax contribution percentage may be limited to a percentage that is
   less than the percentage described in Section entitled YOUR
   CONTRIBUTIONS, as determined by a factor based on the average Employee
   Pre-Tax contribution percentage for non-highly compensated employees.
   Highly compensated employees generally include employees who earn more
   than a specified amount in the preceding Plan Year ($80,000 for 1998
   and 1999, $85,000 for 2000). This amount may be adjusted annually as
   announced by the Internal Revenue Service.

                                      16







   If you are a highly compensated employee and you exceed this limit at
   any time, you will be notified and your future contributions may be
   reduced or stopped, and any excess may be refunded to you.

   MAXIMUM ANNUAL ADDITION LIMIT.

   The maximum amount that may be contributed by you (excluding rollover
   contributions) or on your behalf to this Plan or any other qualified
   defined contribution plan sponsored by Bay State is the lesser of (1)
   25% of your W-2 taxable income (and salary reductions, if any,
   pursuant to Code Section 125, 402(e)(3), 402(h)(l)(B), 403(b),
   408(p)(2)(A)(i) or 457) or (2) $30,000. The $30,000 amount may be
   adjusted annually as announced by the Internal Revenue Service.

   MAXIMUM ELIGIBLE PAY LIMIT.

   The maximum amount of your eligible pay that may be taken into account
   per Plan Year for purposes of contributions is $160,000. This amount
   may be adjusted annually as announced by the Internal Revenue Service.


   INVESTMENT FUNDS, INVESTMENT DIRECTION AND FUND TRANSFERS

   WHO MAKES THE INVESTMENT DECISIONS?

   You make your own investment decisions. Bay State has selected a
   variety of daily valued investment funds with different risk and
   return characteristics. Investment fund information sheets and
   prospectuses provide information about the investment options. If you
   have not received this information or would like updated information,
   you may obtain this information by telephoning 1-800-228-4015 and
   peaking with a participant services representative (or if you are
   hearing impaired, telephone 1-800-637-1215).

   Each of the investment funds has specific investment objectives for
   both risk and expected return. The specific investment funds available
   to you may be changed from time to time. The investment funds include
   a Company Stock Fund, which invests in shares of NiSource Inc.
   ("NiSource") common stock ("Company Stock"). For liquidity purposes, a
   portion of the Company Stock Fund will also be invested in money
   market type assets.

   When you enroll in the Plan you may elect the percentage of your
   Account you want invested in each investment fund. However, the
   Administrator reserves the right to set a maximum percentage of the
   total election that you may direct into any specific investment fund.

   You should make your investment choices based on your investment goals
   and your willingness to assume investment risk in order to realize
   potentially higher returns. Investment risk is defined as a measure of
   how much the investment returns can vary, either up or down, from
   period to period.

                                      17







   HOW MAY I OBTAIN INVESTMENT FUND PERFORMANCE INFORMATION?

   You may obtain recent investment fund performance information by
   telephoning 1-800-228-4015 (or if you are hearing impaired, telephone
   1-800-637-1215).

   HOW MAY I CHANGE MY INVESTMENT DIRECTION AND WHEN DOES MY NEW
   INVESTMENT DIRECTION TAKE EFFECT?

   You may change your investment direction for future contributions and
   loan payments to your Account at any time. Only one investment
   direction will be allowed each day.

   If you telephone on a business day before the close of the New York
   Stock Exchange (4 p.m. Eastern time), your investment change will be
   processed that day. Otherwise it will be processed the next business
   day. For this purpose, a business day is a day on which the stock
   markets are open for trading. A written confirmation of your
   investment direction change will be sent within 48 hours of processing
   the transaction.

   To change your investment direction, refer to Section entitled
   INSTRUCTIONS AT A GLANCE.

   HOW DO I TRANSFER MY FUNDS?

   You may elect to transfer funds by telephoning 1-800-228-4015 (or if
   you are hearing impaired, telephone 1-800-637-1215). Transfers out may
   be requested in terms of dollars, shares or percentages. Dollar and
   percent transfers are based on the previous night's closing Net Asset
   Value and will be converted into a specific number of shares to be
   sold. Transfers in are always in percentages (in 1% increments) and
   must total to 100%. Only one fund transfer per day may be requested.

   In order for a fund transfer to be executed on the same business day
   as the telephone call, it must be completed by 4 p.m. Eastern time.

   To initiate a fund transfer, refer to Section entitled INSTRUCTIONS AT
   A GLANCE.

   INFORMATION REGARDING VOTING AND TENDERING COMPANY STOCK

   You will be entitled to instruct the Plan Trustee as to the voting or
   tendering of any whole and fractional shares of Company Stock held on
   your behalf in the Company Stock Fund.  Nisource will be responsible
   for the timely distribution of proxy solicitation or other material to
   you in connection with any shareholder vote or tender decision,
   including a form for you to complete to instruct the Trustee with
   regard to voting or tendering.

   The Trustee is responsible for tabulating and complying with the
   voting or tendering instructions it receives from participants. The

                                      18







   Trustee will hold your instructions in confidence and will not divulge
   or release specific information regarding such instructions, on an
   individual basis, to any person, including officers or employees of
   NiSource or Bay State, except to the extent required by law.

   If you do not instruct the Trustee with regard to a shareholder vote
   or tender decision, your shares will be voted or tendered as
   instructed by the Committee for the Plan.


   VESTING

   Vesting is a term used to describe the portion of your Account which
   you own. Your balance in each of your Accounts is fully vested at all
   times.


   PARTICIPANT LOANS

   MAY I BORROW FROM MY ACCOUNT?

   You may borrow from all of your Accounts. You may have two loans
   outstanding at a time.

   HOW MUCH MAY I BORROW?

   The minimum loan amount is $1,000.

   The maximum you may borrow is 50% of your vested Account balance or,
   if less, $50,000. The $50,000 amount is reduced by your highest
   outstanding balance on all loans during the preceding 12 months. For
   purposes of this paragraph, all of Bay State's qualified plans are
   considered as part of this Plan to the extent the maximum loan amount
   would be decreased.

   You may obtain information about the amount you may borrow or do
   "modeling" to help you decide on the terms of the loan by telephoning
   1-800-228-4015 (or if you are hearing impaired, telephone 1-800-637-
   1215).

   WHAT IS THE LOAN INTEREST RATE?

   The interest rate is fixed at the time you borrow and shall be a
   reasonable rate of interest, determined by the Plan Administrator,
   which provides the Plan with a return commensurate with the prevailing
   interest rate charged by persons in the business of lending money for
   loans which would be made under similar circumstances.

   The interest rate may be changed from time to time. You may obtain
   information about the current interest rate by telephoning 1-800-228-
   4015 (or if you are hearing impaired, telephone 1-800-637-1215).


                                      19







   WHAT IS THE LOAN REPAYMENT TERM?

   The loan repayment term may be for a period not to exceed five years.

   HOW DO I MAKE LOAN PAYMENTS AND HOW ARE THE PAYMENTS INVESTED?

   Loan payments, consisting of principal and interest, are made through
   convenient payroll deduction (or by check during any period you are
   temporarily ineligible for payroll deduction), and each payment is
   credited to your Account. You may make additional loan payments at any
   time by check or pay off the remaining balance of your loan at any
   time by cashier's check, certified check or money order. You may
   obtain your loan payoff amount by telephoning 1-800-228-4015 (or if
   you are hearing impaired, telephone 1-800-637-1215).

   Loan payments credited to your Account are invested in accordance with
   your current investment instructions for future contributions to your
   Account at the time the loan payment is deposited into your Account.

   WHAT HAPPENS IF MY EMPLOYMENT TERMINATES?

   Your outstanding loan balance is due should your employment with Bay
   State terminate for any reason. Your outstanding loan balance is due
   upon the earlier of the date you request a distribution from your
   Account or approximately 90 days after you terminate employment with
   Bay State. If you do not take action to pay your outstanding loan
   balance before that time, the unpaid balance will become a taxable
   distribution to you, except to the extent any portion of the unpaid
   balance represents a return of after-tax contributions.

   HOW IS MY LOAN SECURED?

   Your loan will be evidenced by a promissory note, secured by the
   portion of your Account from which the loan is made. The Plan shall
   have a lien on this portion of your Account.

   A suspension of loan payments may be authorized for up to 12 months if
   you are on leave of absence without pay. During the suspension period
   interest on your outstanding loan balance will continue to accrue. All
   past due amounts will be due at the end of the suspension period
   unless otherwise authorized.

   A loan is treated as in default if a scheduled loan payment is not
   made at the time required. You will have a grace period to cure the
   default before it becomes final. In the event the default becomes
   final, the default will be treated as a taxable distribution to you,
   except to the extent any portion of the unpaid balance represents a
   return of after-tax contributions. However, your promissory note will
   not be distributed and interest will continue to accrue on your
   outstanding loan balance, until such time as you are otherwise
   eligible for an in-service withdrawal or a distribution from your
   Account.

                                      20







   ARE THERE ANY LOAN FEES?

   If you took a loan prior to May 28, 1999, a loan maintenance fee of
   $3.50 will be assessed to your Account for each month your Account has
   a loan balance. The fee will be charged quarterly to your Account. You
   will see these fees on your quarterly statement. However, for new
   loans initiated after May 28, 1999, there will be a one-time fee of
   $40.00 that will be assessed to your Account at the time you take out
   the loan.

   WHAT HAPPENS WHEN I REQUEST A LOAN?

   Upon processing of your request, your investments will be redeemed as
   needed to fund your loan. Within each Account used for funding your
   loan, amounts will be redeemed from your investment funds in direct
   proportion to the value of your interest in each investment fund as of
   the date the loan is processed. As the Plan's investment funds are
   daily valued investment funds, your investments are redeemed based on
   the value of each such investment on the day your loan is processed.
   Your check and loan documents are generally issued within three
   business days thereafter.

   To request a loan, refer to Section entitled INSTRUCTIONS AT A GLANCE.


   WITHDRAWALS WHILE YOU ARE AN EMPLOYEE

   UNDER WHAT CIRCUMSTANCES MAY I MAKE A WITHDRAWAL FROM THE PLAN WHILE I
   AM AN EMPLOYEE?

   Withdrawals while you are an employee are permitted as described
   below. These withdrawals are referred to as in-service withdrawals.

   There is no minimum amount for any type of in-service withdrawal.

        *    HARDSHIP WITHDRAWAL

             You may make an in-service withdrawal in certain cases of
             financial hardship. You may withdraw from all of your
             Accounts, except for any earnings credited to your Employee
             Pre-Tax Account after December 31, 1988.

             The amount you may withdraw may be no greater than the
             amount necessary to satisfy your financial need including
             amounts necessary to pay any federal, state or local income
             taxes or penalties reasonably anticipated to result from the
             withdrawal.

             For this purpose, hardship is a financial need to:

        *    Purchase your principal residence.


                                      21







             Pay unreimbursable medical expenses incurred or to be
             incurred by you, your spouse or dependents.

        *    Pay unreimbursable tuition, related educational fees and
             room and board for up to the next 12 months of post-
             secondary education for you, your spouse or dependents.

        *    Pay amounts necessary to prevent losing your principal
             residence through eviction or foreclosure on your mortgage.

             You may qualify for a Hardship Withdrawal by first borrowing
             and withdrawing all other available amounts from this Plan
             (and from any other plan maintained by Bay State), other
             than hardship withdrawals. You will be ineligible to
             contribute to the Plan for 12 months from the date of your
             Hardship Withdrawal.

             A special limitation may reduce the maximum amount of
             Employee Pre-Tax contributions you may contribute in the
             calendar year following the calendar year of your Hardship
             Withdrawal.

        *    PRIOR AFTER-TAX ACCOUNT WITHDRAWAL

             You may make a Prior After-Tax Account Withdrawal once in
             any 12-month period.

        *    ROLLOVER ACCOUNT WITHDRAWAL

             You may make a Rollover Account Withdrawal once in any 12-
             month period.

        *    OVER AGE 59-1/2 WITHDRAWAL

             Once you have attained age 59-1/2 , you may make an Over Age
             59-1/2 Withdrawal once in any 12-month period.

             You may withdraw from all of your Accounts. If you have a
             Prior After-Tax Account, you will need to designate whether
             you want to withdraw from this Account first as part of your
             Over Age 59-1/2 Withdrawal.

        *    PRIOR COMPANY ACCOUNT PLUS WITHDRAWAL

             You may make a Prior Company Account Plus Withdrawal once in
             any 12-month period.

             You may withdraw from your Prior After-Tax, Rollover and
             Prior Company Accounts.




                                      22





   WHAT ARE MY IN-SERVICE WITHDRAWAL PAYMENT OPTIONS?

   Your in-service withdrawal will be paid in a single lump sum, in cash.

   WHAT ARE MY IN-SERVICE WITHDRAWAL METHODS?

   You may choose to have all or a portion of your in-service withdrawal
   that is eligible for rollover be made payable directly to an IRA,
   another employer's qualified plan or to you. The portion of your in-
   service withdrawal representing a return of after-tax contributions
   and, effective January 1, 1999 the portion of your hardship withdrawal
   representing Employee Pre-Tax contributions, are not eligible for
   rollover and will be made payable to you. Regarding the portion of
   your in-service withdrawal that is eligible for rollover and that is
   made payable to you, the law requires that 20% of that amount be
   withheld for federal taxes. Your actual tax liability may be more or
   less depending on your personal tax situation.

   WHAT HAPPENS WHEN I REQUEST AN IN-SERVICE WITHDRAWAL?

   An IRS Tax Notice is required to be provided to you no more than 90
   days before your in-service withdrawal is made. The IRS Tax Notice
   summarizes the rules related to rollovers, income tax and penalties
   that may apply to your in-service withdrawal. You should review the
   IRS Tax Notice prior to requesting an in-service withdrawal.

   Upon processing of your request, your investments will be redeemed as
   needed to fund your in-service withdrawal. Within each Account used
   for funding your in-service withdrawal, amounts will be redeemed from
   your investment funds in direct proportion to the value of your
   interest in each investment fund as of the date the in-service
   withdrawal is processed. As the Plan's investment funds are daily
   valued investment funds, your investments are redeemed based on the
   value of each such investment on the day your in-service withdrawal is
   processed. Your check is generally issued within three business days
   thereafter.

   To request an in-service withdrawal, refer to Section entitled
   INSTRUCTIONS AT A GLANCE.

   WHAT ARE THE TAXES AND PENALTIES FOR IN-SERVICE WITHDRAWALS?

   The IRS Tax Notice summarizes the rules related to rollovers, income
   tax and penalties that may apply to your in-service withdrawal.


   DISTRIBUTIONS AFTER YOU TERMINATE EMPLOYMENT WITH BAY STATE

   WHAT ARE MY DISTRIBUTION PAYMENT OPTIONS?

   If your vested Account balance is $5,000 or less, your distribution
   payment options are limited to a single lump sum. Otherwise, you may
   choose to have your vested Account balance distributed as follows:


                                      23







        *    paid in a single lump sum,

        *    a portion paid in a lump sum, and the remainder paid later,
             or

        *    paid in periodic installments over a period not to exceed
             the life expectancy of you and your beneficiary.

   Your distribution will  be paid in cash,  except to the extent  of the
   distribution of your outstanding loan  balance, if any, and except (if
   your Account is distributed in a lump sum) to the extent you choose to
   receive the portion of your distribution attributable to  your Account
   balance invested in the Company Stock Fund in the form of whole shares
   of Company Stock and cash in lieu of fractional shares.

   WHAT ARE MY DISTRIBUTION METHODS?

   You may choose to have all or a portion of your distribution that is
   eligible for rollover be made payable directly to an IRA, another
   employer's qualified plan or to you. The portion of your distribution
   representing a return of after-tax contributions is not eligible for
   rollover and will be made payable to you. If your vested Account
   balance is $5,000 or less and you do not request a distribution, your
   vested Account balance may be distributed to you without your consent
   in a check made payable to you.

   Regarding the portion of your distribution that is eligible for
   rollover and that is made payable to you, the law requires that 20% of
   that amount be withheld for federal taxes. Your actual tax liability
   may be more or less depending on your personal tax situation.

   If you elect distribution in periodic installments, your Account will
   be charged a fee for each installment payment. You will see these fees
   on your quarterly statement. Currently, this fee is $3.00 per check
   and may be changed from time to time.

   WHEN ARE DISTRIBUTIONS MADE?

   You may generally choose when to take a distribution of your vested
   Account balance following your termination of employment with Bay
   State. Prior to 1999, the law required that you start taking
   distributions from your Account on or before the April 1 immediately
   after the later of the end of the calendar year in which you reach age
   70-1/2 or the end of the calendar year in which your employment with
   Bay State terminates. Beginning in 1999, your distribution must begin
   upon the later of your attainment of age 70-1/2 or your termination of
   employment with Bay State.

   If your vested Account balance is $5,000 or less, you should request a
   distribution of your vested Account balance at the time you terminate
   employment with Bay State or shortly thereafter. If you do not request
   a distribution, your vested Account balance may be distributed to you

                                      24







   without your consent in a check made payable to you. Mandatory 20%
   federal tax withholding will apply as described above.

   If you are eligible and choose to defer distribution of your Account
   after your employment with Bay State terminates, an administrative fee
   will continue to be assessed to your Account each month and charged
   quarterly to your Account as described in Section entitled OTHER
   THINGS YOU SHOULD KNOW.

   Your Account will continue to be invested as you direct until it is
   distributed to you.

   WHAT HAPPENS WHEN I REQUEST A DISTRIBUTION?

   An IRS Tax Notice is required to be provided to you no more than 90
   days before your distribution is made. The IRS Tax Notice summarizes
   the rules related to rollovers, income tax and penalties that may
   apply to your distribution. You should review the IRS Tax Notice prior
   to requesting a distribution.

   Upon processing of your request, your investments will be redeemed as
   needed to fund your distribution. Within each Account used for funding
   your distribution, amounts will be redeemed from your investment funds
   in direct proportion to the value of your interest in each investment
   fund as of the date the distribution is processed. As the Plan's
   investment funds are daily valued investment funds, your investments
   are redeemed based on the value of each such investment on the day
   your distribution is processed. Your check is generally issued within
   three business days thereafter. If you choose to receive the portion
   of your distribution attributable to your Account balance in the
   Company Stock Fund in the form of whole shares of Company Stock and
   cash in lieu of fractional shares, your stock certificate will be
   issued within a few weeks thereafter.

   To request a distribution upon termination of employment with Bay
   State, refer to Section entitled INSTRUCTIONS AT A GLANCE.

   WHAT ARE THE TAX TREATMENTS, TAXES AND PENALTIES FOR DISTRIBUTIONS?

   The IRS Tax Notice summarizes the rules related to rollovers, tax
   treatments, income tax and penalties that may apply to your
   distribution.


   DEATH BENEFITS

   WHAT HAPPENS TO MY PLAN BENEFIT IF I DIE?

   Upon your death, your Account becomes payable to your
   beneficiary(ies). If you die while an employee, your Account will
   become fully vested, if not otherwise fully vested. In general, your
   beneficiary has the same options as you do regarding when and how to

                                      25







   receive payment, except that a distribution to your beneficiary may
   only be eligible for rollover if your beneficiary is your spouse. Your
   beneficiary should contact the benefits department for further
   instructions.

   HOW MAY I DESIGNATE MY BENEFICIARY?

   When you become eligible to participate in the Plan or, if earlier, at
   the time you make a Rollover Contribution, you must complete and file
   a Beneficiary Designation Form stating who is to receive your Account
   balance if you die. You may change your beneficiary(ies) at any time
   by completing and filing a new Beneficiary Designation Form. The
   change takes effect on the date your new completed Beneficiary
   Designation Form is on file with the benefits department.

   If you are married, your spouse is automatically your sole primary
   beneficiary. To designate someone in addition to or other than your
   spouse as a primary beneficiary, you must obtain your spouse's written
   consent to your designation and your spouse's signature must be
   witnessed by a Plan representative or Notary Public. If you complete
   and file a Beneficiary Designation Form and later become married or
   remarry, your earlier Beneficiary Designation Form will not be valid.
   You will need to complete and file a new Beneficiary Designation Form.

   If you fail to complete and file a Beneficiary Designation Form before
   you die, your benefit upon death will be paid to the individual(s) in
   the first of the following categories in which there is at least one
   survivor: your spouse; your children (in equal shares), by right of
   representation; or your estate.


   REEMPLOYMENT WITH BAY STATE

   WHEN CAN I RESUME MY PARTICIPATION?

   If you were a Plan participant before your employment with Bay State
   terminated and you are rehired by Bay State, you may resume
   participation on the date of your rehire as an eligible employee. If
   you were not a participant when your employment with Bay State
   terminated, or were not eligible for Employer contributions, you will
   enter the Plan or become eligible for Employer contributions as
   described in Section entitled ELIGIBILITY, but no earlier than the
   date you would have entered the Plan or become eligible for Employer
   contributions if you had not terminated your employment with Bay
   State.

   FUTURE OF THE PLAN

   Bay State intends for the Plan to be a permanent part of your total
   benefits program. However, Bay State reserves the right to terminate
   the Plan at any time.


                                      26







   Bay State reserves the right to amend the Plan at any time if it
   becomes desirable or necessary. You will be notified within 210 days
   after the end of the Plan Year of any relevant Plan amendment. The
   Plan (including any amendments) is subject to approval by the IRS.
   From time to time, changes in the details of the Plan may be required
   by the IRS. However, no Plan amendment may take away any benefits you
   have earned.

   As the Plan benefits are provided by individual participant accounts,
   benefits under this Plan are not insured by the Pension Benefit
   Guaranty Corporation (PBGC). PBGC insurance does not apply to this
   type of plan.


   PLAN ADMINISTRATION ISSUES

   ACCOUNT STATEMENTS AND ACCOUNT INFORMATION

   You will receive statements four times each year. They will normally
   be sent to you within three weeks after the end of each quarter of the
   Plan Year.

   You have easy access to information regarding your Account at any
   time.

   To obtain information regarding your Account, refer to Section
   entitled INSTRUCTIONS AT A GLANCE.

   PLAN ADMINISTRATOR

   The Bay State Gas Company Benefits Committee is the Plan
   Administrator.  Bay State has appointed this Benefits Committee and
   delegated to it all or part of its duties to oversee the Plan's
   operations. As a Plan fiduciary, the Plan Administrator acts on your
   behalf to see that the Plan is administered fairly according to
   standards outlined in the law and the terms of the Plan and Trust
   Agreement.

   Plan records are maintained on a Plan Year basis. The Plan Year ends
   on December 31.

   HOURS OF SERVICE

   Hours of service are used in determining your eligibility to
   participate. You earn one hour of service for each hour you are paid
   by Bay State (including any back pay you may be awarded). This
   includes hours when you do not actually work but receive pay (such as
   vacation, holiday, jury duty, illness or incapacity, such as
   disability). You receive credit for non-paid company time, such as a
   leave of absence approved by Bay State, military duty or a temporary
   layoff.


                                      27







   Service earned while you are not actively at work is based on your
   normally scheduled weekly hours. If you are a salaried employee, or
   there are no accurate records of your working hours, you will be
   credited with a set number of hours for each pay period in which you
   are paid for at least one hour. The rates of hours credited for each
   pay period are: 45 hours per weekly pay period, 90 hours per bi-weekly
   pay period, 95 hours per semi-monthly pay period and 190 hours per
   monthly pay period.

   AGENT FOR SERVICE OF LEGAL PROCESS

   Service of legal process may be made upon the Clerk of Bay State at
   the address listed in Section entitled PLAN DIRECTORY.

   TYPE OF PLAN

   This Plan is a profit sharing plan with a pre-tax salary deferral
   (401(k)) feature.

   TOP HEAVY CONTRIBUTION PROVISIONS

   The Plan includes provisions which apply only if the Plan is "top
   heavy." A plan is top heavy if more than 60% of the total plan assets
   belong to "key employees." Key employees include certain officers,
   shareholders and owners. If the plan is top heavy, contributions may
   not be made by or on behalf of key employees, other than a Rollover
   contribution, unless Bay State makes a minimum contribution to all
   eligible employees.


   OTHER THINGS YOU SHOULD KNOW

   TRUST FUND

   All of the Plan's assets are held in a trust fund which is the sole
   source of all benefit payments. The trust fund is a separate and
   distinct legal entity, and is not part of Bay State. The assets of the
   trust fund are not commingled with Bay State's assets. Generally, no
   part of the trust fund can be attached by creditors of any Plan
   participant or of Bay State. Assets of the trust fund are held
   exclusively to pay Plan benefits and expenses, and cannot revert to or
   be paid to Bay State, except under certain limited circumstances
   permitted by law.

   The Plan Trustee holds the Plan's assets, executes all of the
   investments, maintains the financial records relating to the trust,
   and makes all benefit payments as directed by the Plan Administrator.

   PLAN FEES AND EXPENSES

   Bay State pays all administrative fees and expenses related to
   maintaining the Plan as a whole. Bay State may, at a later date,

                                      28







   choose to have all or a portion of such fees and expenses paid by
   participants. Bay State will notify you in advance of any such change.
   If changed, an administrative fee will be assessed to your Account
   each month and charged quarterly to your Account, except that no fee
   may reduce your Account balance below zero.

   You will pay any special fees related to your own Account, such as
   loan fees and fees for installment payments. You will see these fees
   on your quarterly statement.

   PLAN PARTICIPATION PURSUANT TO A COLLECTIVE BARGAINING AGREEMENT

   The Plan is maintained pursuant to one or more collective bargaining
   agreements. You may obtain a copy of each such collective bargaining
   agreement by contacting the Plan Administrator or Human Resources.

   CLAIM REVIEW PROCEDURES

   As the Plan Administrator, the Benefits Committee is responsible for
   determining and informing you of your entitlement to a benefit and of
   any amounts payable to you. If you disagree with a decision, you or
   your authorized representative may ask for a review by submitting a
   written request to the benefits department. Your request should
   include the issues and comments you feel are important. You also have
   the right to review pertinent documents.

   The review process sets the following limits on the amount of time you
   may take to make your request and for the Plan Administrator to
   respond:

                                                       DAYS TO RESPOND
   ACTION                                             FROM PRIOR ACTION
   ------                                             -----------------

   Plan Administrator sends you a benefit statement             -
   You request an initial review . . . . . . . . . . . . . . . 60 days
   Plan Administrator sends you its initial decision . . . . . 90 days
   You request a final review. . . . . . . . . . . . . . . . . 60 days
   Plan Administrator sends you its final decision . . . . . . 60 days


   The Plan Administrator will either approve your claim or explain why
   your claim is being denied (by referring to specific Plan provisions)
   and how applications are reviewed. In special circumstances, the Plan
   Administrator may notify you and take up to an additional 90 days for
   its initial review and 60 days for its final review.

   NO ASSIGNMENT OF YOUR ACCOUNT IS PERMITTED

   Under this Plan, you may not assign, sell, transfer or use your
   Account as collateral, other than for a loan from your Account as


                                      29







   described in Section entitled PARTICIPANT LOANS. In addition,
   creditors may not attach your Account as a means of collecting debts.
   However, the Plan Administrator will comply with a "qualified domestic
   relations  order" (QDRO). This  is an order  or judgment  from a state
   court  directing that a participant's  Account, or portion thereof, be
   paid  to an  Alternate Payee  (spouse, former  spouse, child  or other
   dependent of the participant) as child  support, alimony or part of  a
   division  of marital  property rights, provided  that the  order meets
   certain requirements of federal law.

   NO EMPLOYMENT RIGHTS

   Your participation in the Plan does not give you any employment rights
   with Bay State.

   YOUR RIGHTS UNDER FEDERAL LAW

   As a participant of this Plan you are entitled to certain rights and
   protection under the Employee Retirement Income Security Act of 1974
   ("ERISA"). ERISA provides that all Plan participants shall be entitled
   to:

        *    examine, without charge, at the Plan Administrator's office,
             all Plan documents and copies of all documents filed by the
             Plan with the U.S. Department of Labor, such as annual
             reports;

        *    obtain copies of all Plan documents and information upon
             written request to the Plan Administrator. The Plan
             Administrator may make a reasonable charge for the copies;

        *    receive a summary of the Plan's annual financial report. The
             Plan Administrator is required by law to furnish each
             participant with a copy of this summary annual report; and

        *    obtain a statement telling you the amount of your Account
             balance, the portion of your Account balance you currently
             have a right to and when you will have the right to receive
             payment. If you do not have a right to a benefit, the
             statement will tell you how many years you have to work to
             get this right. This statement must be requested in writing
             and is not required to be given more than once a year. The
             Plan Administrator must provide the statement free of
             charge.

   In addition to creating rights for Plan participants, ERISA imposes
   duties upon the people who are responsible for the operation of the
   Plan. The people who operate your Plan, called "fiduciaries" of the
   Plan, have a duty to do so prudently and in the interest of you and
   other Plan participants and beneficiaries.



                                      30







   No one, including your employer or any other person, may terminate you
   or otherwise discriminate against you in any way to prevent you from
   obtaining a benefit or exercising your rights under ERISA.

   If your claim for a  benefit is denied in whole  or in part, you  must
   receive a written explanation  of the reason for the  denial. You have
   the right  to have the  Plan Administrator review and  reconsider your
   claim.

   Under ERISA, there are steps you can take to enforce the above rights.
   For instance, if you request written materials from the Plan
   Administrator and do not receive them within 30 days, you may file
   suit in federal court. In such a case, the court may require the Plan
   Administrator to provide the materials and pay you up to $100 a day
   until you receive the materials, unless the materials were not sent
   because of reasons beyond the control of the Plan Administrator.

   If you have a claim for a benefit which is denied or ignored, in whole
   or in part, you may file suit in a state or federal court. If it
   should happen that Plan fiduciaries misuse the Plan's money, or if you
   are discriminated against for asserting your rights, you may seek
   assistance from the U.S. Department of Labor, or you may file suit in
   a federal court. The court will decide who should pay court costs and
   legal fees. If you are successful, the court may order the person you
   have sued to pay these costs and fees. If you lose, the court may
   order you to pay the costs and fees if, for example, it finds your
   claim is frivolous.

   If you have any questions about your Plan, you should contact the
   benefits department. If you have any questions about this statement of
   your rights under ERISA, you should contact the nearest Area Office of
   the Pension and Welfare Benefits Administration, U.S. Department of
   Labor.

   ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Delaware General Corporation Law permits a corporation to
   indemnify any person who is a party or is threatened to be made a
   party to any action, suit or proceeding brought or threatened by
   reason of the fact that the person is or was a director, officer,
   employee or agent of the corporation, or is or was serving as such
   with respect to another corporation at the request of the corporation,
   if that person acted in good faith, in the case of conduct in his or
   her official capacity, that person reasonably believed his or her
   conduct to be in the best interests of the corporation, or in the case
   of all other conduct, that person reasonably believed his or her
   conduct was not opposed to the best interests of the corporation, and
   with respect to any criminal action, that person had reasonable cause
   to believe his or her conduct was lawful or had no reasonable cause to
   believe his or her actions were unlawful.

        A corporation must indemnify a person who was or is a party or is
   threatened to be made a party to any threatened, pending or completed
   action, suit or proceeding, because he or she is or was a director or
   officer or is or was serving at the request of the corporation as a
   director or officer of another corporation or other enterprise, if the
   person has been wholly successful in defense of the proceeding on the
   merits or otherwise.  A corporation may advance expenses, including
   attorneys' fees, to any director or officer who is a party to a
   proceeding in advance of final disposition of the proceeding if the
   director or officer furnishes the corporation a written undertaking to
   repay the advance if it is ultimately determined that the director did
   not meet the required standard of conduct.  Amounts to be indemnified
   include judgments, penalties, fines, settlements and reasonable
   expenses that were actually incurred by the person.  However, if the

                                      36







   proceeding was by or in the right of the corporation, the person will
   be indemnified only against reasonable expenses incurred and
   indemnification will not be provided if the individual is adjudged
   liable to the corporation in the proceeding.

        The Company's certificate of incorporation permits the Company to
   indemnify directors, officers, employees and agents of the corporation
   and its wholly-owned subsidiaries to the fullest extent permitted by
   law.

        As authorized under the Company's  By-Laws and the Delaware
   General Corporation Law, the Company and its subsidiaries maintain
   insurance that insures directors and officers for acts committed in
   their capacities as such directors or officers that are determined to
   be not indemnifiable under the Company's indemnity provisions.

        Section 6.10 of the Agreement and Plan of Merger dated as of
   February 27, 2000, as amended and restated as of March 31, 2000, among
   Columbia Energy Group, NiSource Inc., New NiSource Inc., Parent
   Acquisition Corp., Company Acquisition Corp. and NiSource Finance
   Corp. (the "Merger Agreement") provides for indemnification by the
   Company under certain circumstances of the directors and officers of
   Columbia.  Additionally, the Merger Agreement provides that the
   Company will maintain Columbia's existing officers' and directors'
   insurance policies or provide substantially similar insurance coverage
   for at least six years.

   ITEM 16.  EXHIBITS.

        The Exhibits filed herewith are set forth on the Exhibit Index
   filed as part of this Registration Statement.

   ITEM 17.  UNDERTAKINGS.

        The Registrants hereby undertake:

        (1)  To file, during any period in which offers or sales are
   being made, a post-effective amendment to this registration statement:

             (i)  To include any prospectus required by Section 10(a)(3)
        of the Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events
        arising after the effective date of the registration statement
        (or the most recent post-effective amendment thereof) which,
        individually or in the aggregate, represent a fundamental change
        in the information set forth in the registration statement.
        Notwithstanding the foregoing, any increase or decrease in volume
        of securities offered (if the total dollar value of securities
        offered would not exceed that which was registered) and any
        deviation from the low or high end of the estimated maximum
        offering range may be reflected in the form of a prospectus filed

                                      37







        with the Commission pursuant to Rule 424(b) if, in the aggregate,
        the changes in volume and price represent no more than a 20
        percent change in the maximum aggregate offering price set forth
        in the "Calculation of Registration Fee" table in the effective
        registration statement; and

             (iii)     To include any material information with respect
        to the plan of distribution not previously disclosed in the
        registration statement or any material change to such information
        in the registration statement;

   PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if
   the registration statement is on Form S-3 or Form S-8, and the
   information required to be included in a post-effective amendment by
   those paragraphs is contained in periodic reports filed with or
   furnished to the Commission by the Registrant pursuant to Section 13
   or 15(d) of the Securities Exchange Act of 1934 that are incorporated
   by reference in the registration statement.

        (2)  That, for the purpose of determining any liability under the
   Securities Act of 1933, each such post-effective amendment shall be
   deemed to be a new registration statement relating to the securities
   offered therein, and the offering of such securities at that time
   shall be deemed to be the initial BONA FIDE offering thereof.

        (3)  To remove from registration by means of a post-effective
   amendment any of the securities being registered which remain unsold
   at the termination of the offering.

        The registrants hereby undertake that, for purposes of
   determining any liability under the Securities Act of 1933, each
   filing of an annual report pursuant to Section 13(a) or Section 15(d)
   of the Securities Exchange Act of 1934 (and, where applicable, each
   filing of an employee benefit plan's annual report pursuant to Section
   15(d) of the Securities Exchange Act of 1934) that is incorporated by
   reference in the registration statement shall be deemed to be a new
   registration statement relating to the securities offered therein, and
   the offering of such securities at that time shall be deemed to be the
   initial BONA FIDE offering thereof.

        Insofar as indemnification for liabilities arising under the
   Securities Act of 1933 may be permitted to directors, officers and
   controlling persons of the Registrants pursuant to the foregoing
   provisions, or otherwise, the registrants have been advised 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.  In the event that a claim for
   indemnification against such liabilities (other than the payment by
   the registrants of expenses incurred or paid by a director, officer or
   controlling person of the registrants in the successful defense of any
   action, suit or proceeding) is asserted by such director, officer or
   controlling person in connection with the securities being registered,

                                      38







   the registrants will, unless in the opinion of its counsel the matter
   has been settled by controlling precedent, submit to a court of
   appropriate jurisdiction the question whether such indemnification by
   it is against public policy as expressed in the Act and will be
   governed by the final adjudication of such issue.
