                                   NIPSCO

        NIPSCO is an energy and utility-based holding company that
   provides natural gas, electricity, water and related services for
   residential, commercial and industrial uses through a number of
   wholly-owned regulated and non-regulated subsidiaries.  NIPSCO
   operates primarily in Indiana and, with the acquisition of Bay State
   Gas Company ("Bay State"), New England.

        NIPSCO distributes natural gas to approximately 739,000 customers
   in Northern Indiana through three wholly-owned utility subsidiaries:
   Northern Indiana Public Service Company ("Northern Indiana"), Kokomo
   Gas and Fuel Company ("Kokomo Gas") and Northern Indiana Fuel and
   Light Company, Inc. ("NIFL").  Northern Indiana, Kokomo Gas and NIFL
   operate in 41 counties across Northern Indiana, serving an area of
   about 13,865 square miles with a population of approximately 2.4
   million.  Bay State distributes natural gas to more than 300,000
   customers in the areas of Brockton, Lawrence and Springfield,
   Massachusetts, Lewiston and Portland, Maine and Portsmouth, New
   Hampshire.  Bay State operates in 12 counties in New England, serving
   an area of about 2,152 square miles with a population of approximately
   1.8 million.  Based on total throughput, NIPSCO is the tenth largest
   local gas distribution company in the United States.

        NIPSCO's wholly-owned subsidiary, Crossroads Pipeline Company
   ("Crossroads" and, together with Northern Indiana, Kokomo Gas and
   NIFL, the "Energy Utilities"), owns and operates an interstate
   pipeline extending from the northwestern corner of Indiana (near the
   border with Chicago) eastward into Ohio.  In addition, NIPSCO and Bay
   State collectively own a 19% share of Portland Natural Gas
   Transmission System ("PNGTS"), a 292-mile pipeline being built to
   bring Canadian gas from New Brunswick into Maine, New Hampshire and
   Massachusetts in order to increase the gas supply to the region.

        NIPSCO generates and distributes electricity to the public
   primarily through its largest subsidiary, Northern Indiana.  Through
   its Primary Energy, Inc. ("Primary Energy") subsidiary, NIPSCO also is
   active in developing unregulated power projects.  Northern Indiana
   provides electric services in 30 counties in the northern part of
   Indiana, with an area of approximately 12,000 square miles and a
   population of approximately 2.2 million.  At September 30, 1998,
   Northern Indiana provided approximately 419,000 customers with
   electricity.  For the twelve months ended September 30, 1998,
   industrial customers accounted for approximately 42% of Northern
   Indiana's electric energy revenues, with residential customers
   providing approximately 30% and commercial customers contributing
   approximately 28%.

        NIPSCO operates the sixth largest investor-owned water utility
   business in the United States, serving approximately 252,200 customers
   through the utility subsidiaries of IWC Resources Corporation
   ("IWCR").  These companies supply water for residential, commercial
   and industrial uses and for fire protection services in Indianapolis

                                      1



   and the surrounding areas.  The territory served by the water
   utilities covers an area of approximately 309 square miles in six
   counties of central Indiana.  IWCR also manages the municipal water
   system for Lawrence, Indiana, and participates in partnerships that
   operate municipal wastewater treatment facilities in Indianapolis and
   Gary, Indiana.

        In addition to the activities of Primary Energy described above,
   NIPSCO provides non-regulated energy services through its wholly-owned
   subsidiaries, NI Energy Services, Inc. ("NESI") and Energy USA, Inc. 
   NESI provides a variety of energy-related services, including gas
   marketing, power generation, gas transmission, supply and storage and
   energy efficiency design services.  EnergyUSA markets products and
   services, such as propane, energy advisory services and home security
   services, to customers of local utilities in 22 states.  These
   products and services are branded and operated either under the local
   utility's label or with the EnergyUSA name.

        NIPSCO also provides non-regulated utility-related services,
   including installation, repair and maintenance of underground
   pipelines used in gas, water and sewer transmission and distribution
   systems and underground utility locating and marking services.

   PURPOSE OF THE PLAN

        The Plan is for the benefit of eligible employees and former
   employees of Bay State and affiliated companies and their
   beneficiaries.  The purpose of the Plan is to provide such eligible
   employees a profit-sharing and 401(k) plan designed to help accumulate
   savings for retirement and achieve future financial goals.

        The Plan offers these advantages:

                  deduction.

               THE BAY STATE GAS COMPANY EMPLOYEE SAVINGS PLAN

   General
   -------

   The following is a description of the Plan. It is intended to
   constitute a "summary plan description" pursuant to the Employee
   Retirement Income Security Act of 1974, as amended (ERISA).  This
   description summarizes certain material provisions of the Plan, and as
   such, it does not purport to be complete and is qualified in its
   entirety by reference to the Plan.  Terms used herein and not
   otherwise defined shall have the respective meanings set forth in the
   Plan.

   Introduction
   ------------

   Effective January 1, 1979, Bay State Gas Company (the "Company")
   established the Bay State Gas Company Employee Savings Plan (the
   "Plan").  The Bay State Gas Company Employee Stock Ownership Plan was
   merged into this Plan effective July 1, 1987.

   Effective as of February 12, 1999, the Company was merged into NIPSCO
   Industries, Inc. and became a wholly owned subsidiary of NIPSCO.
   Effective as of April 15, 1999, NIPSCO Industries, Inc. changed its
   name to NiSource Inc. (hereinafter referred to as "NIPSCO").
   As a result of the merger, all of the shares of common stock
   of Bay State have been converted into the right to receive cash or
   shares of common stock of NIPSCO (the "Common Shares") and amounts
   held under the Plan that are subsequently transferred into or
   contributed to the Common Stock Fund will be invested in Common
   Shares.  Notwithstanding the corporate merger, the Plan continues to
   be maintained by the Company.

   The Plan is governed by the official text of the Plan and Trust
   Agreement.  The purpose of this Summary Plan Description is to provide
   a simplified description of how the Plan works.  If the meaning of the
   Plan and Trust Agreement differs from that of the Summary Plan


                                      3



   Description in any way, the official text of the Plan and Trust
   Agreement will govern in administering the Plan.

   References to the Company generally mean Bay State Gas Company, and,
   if applicable, its affiliated companies participating in the Plan as
   the context requires, except, that with regard to issues related to
   service credit, termination of employment or reemployment, references
   to Bay State shall also include any affiliated companies not
   participating in the Plan.  With regard to primarily administrative
   matters, however, references to Bay State mean Bay State Gas Company,
   the Plan Sponsor and Plan Administrator.

   Eligibility
   -----------

        WHO IS ELIGIBLE?

        All employees of the Company who are classified as
        "Administrative, Professional and Supervisory" ("APS") or
        "Clerical/Technical" ("C/T") are eligible except any employee who
        is covered by a collective bargaining agreement which does not
        specifically call for his or her participation in this Plan.

        WHEN DOES PARTICIPATION BEGIN?

        For purposes of Employee Pre-Tax contributions, you will be
        eligible to participate on the first day of the next month after
        you have completed 60 days of service.

        For purposes of Employer Match contributions, your participation
        will begin on the first day of the next month after completion of
        a 12-month eligibility period in which you are credited with at
        least 1,000 hours of service during that period.  Your initial
        eligibility period begins on your date of hire.  Subsequent
        eligibility periods begin with the start of the next Plan Year
        (the calendar year) beginning after your date of hire.

        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 the Company (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, sickness or incapacity,
        such as disability).  You receive credit for non-paid Company
        time, such as a Company-approved leave of absence, military duty
        or a temporary layoff.

        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

                                      4



        hours credited for each pay period are: 45 hours per weekly pay
        period, 90 hours per biweekly pay period, 95 hours per semi-
        monthly pay period and 190 hours per monthly pay period.

        To enroll, refer to Section entitled INSTRUCTIONS AT A GLANCE.

   Your Contributions
   ------------------

   You may elect to contribute regularly through payroll deductions once
   you are eligible to participate.  Your contributions are based on your
   eligible pay.  Eligible pay for this purpose is straight time wages,
   exclusive of all daily or weekly overtime, bonuses, supplementary
   compensation payments, retirement benefits and other forms of non-
   recurring compensation, but inclusive of shift differentials,
   Saturday/Sunday premiums, compensation paid at an alternative rate
   (not including compensation paid at an alternative rate if you are a

        EMPLOYEE PRE-TAX CONTRIBUTIONS

        You may choose to save pre-tax dollars by electing in writing to
        contribute any percentage, up to 15%, of your eligible pay,
        subject to an annual contribution maximum.  Refer to item (a) of
        Section entitled ANNUAL CONTRIBUTION AND COMPENSATION MAXIMUMS. 
        If you are a highly compensated employee, as defined by the
        Internal Revenue Code and related regulations, you may be limited
        to a percentage that is less than 15%.  Refer to item (b) of

        Your Employee Pre-Tax contributions are deposited into your
        Employee Pre-Tax Account.<1>

        CHANGING, DISCONTINUING OR RESUMING YOUR CONTRIBUTIONS

        You may change your contribution percentage election as of the
        first day of any month.  Your payroll deductions will change the

        first time you are paid after your written request has been
        processed.

        You may discontinue contributions at any time.  Your payroll
        deductions will stop the first time you are paid after your
        written request has been processed.  You may resume contributions
        as of the first day of any month.  Your payroll deductions will
        resume the first time you are paid after your written request has
        been processed. If you discontinue contributions more than once
        in a twelve month period, the Plan Administrator reserves the
        right to require a longer waiting period before you can resume
        contributions.

        To 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 the Company) 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.<2>

        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 which may also include a Prior Company
        Account for contributions made under former Plan provisions.

   Company Contributions
   ---------------------

   You will be eligible for Company contributions as described below,
   once you are eligible to participate for this purpose as described in
   Section entitled ELIGIBILITY.

   ____________________

        EMPLOYER MATCH CONTRIBUTIONS

        One of the benefits of contributing on a pre-tax basis under the
        Plan is that the Company matches a portion of such contributions
        under one of the following two formulas.

        FORMULA # 1:

        For each pre-tax dollar you contribute, the Company will
        contribute as follows:


                        EMPLOYEE PRE-TAX
                       CONTRIBUTION AS A
                         PERCENTAGE OF        EMPLOYER MATCH
                          ELIGIBLE PAY          PERCENTAGE
                          ------------           ---------

                            First 5%                50%


        FORMULA # 2:

        If you: (i) were an employee prior to September 1, 1990 and under
        age forty-five on January 1, 1992, or (ii) became an employee on
        or after September 1, 1990, or (iii) were an employee prior to
        September 1, 1990, at least age forty-five on January 1, 1992 and
        irrevocably elected to waive eligibility for post-retiree medical
        coverage no later than September 1, 1992, for each pre-tax dollar
        you contribute, the Company will contribute as follows:


                         EMPLOYEE PRE-TAX
                        CONTRIBUTIONS AS A
                          PERCENTAGE OF         EMPLOYER MATCH
                           ELIGIBLE PAY           PERCENTAGE
                           ------------           ----------
                           First 2 1/2%              100%

                             Next 5%                  50%


        Employer Match contributions are deposited to your Account as
        soon as administratively feasible following each of your
        contributions.









                                      7



        Employer Match contributions made on your behalf are deposited
        into your Employer Match Account.<3>

        SEPARATE ACCOUNTS

        Separate Accounts will be maintained for your Company
        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:

        (a)  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 maintained by any other employer) is $10,000 per
             calendar year, and may be adjusted periodically as announced
             by the Internal Revenue Service.

             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.

        (b)  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
             amount for non-highly compensated employees.  Highly
             compensated employees generally include employees who earn
   ____________________                       

   <3>If you are a former participant of the Bay State Gas Company
   Savings Plan for Operating Employees, your Employer Match Account may
   include amounts transferred on your behalf from the Bay State Gas
   Company Savings Plan for Operating Employees designated as "Employer
   Account" amounts under that plan.

                                      8



             more than $80,000 per year, and may be adjusted periodically
             as announced by the Internal Revenue Service.

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

        (c)  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
             the Company is the lesser of (1) 25 % of your W-2 taxable
             income or (2) $30,000.  The $30,000 amount may be adjusted
             periodically as announced by the Internal Revenue Service.

        (d)  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
             $150,000, and may be adjusted periodically as announced by
             the Internal Revenue Service ($160,000 for the Plan Year
             ending December 31, 1999).  The $150,000 threshold was set
             in 1994.

   Investment Funds and Investment Instructions
   --------------------------------------------

        WHO MAKES THE INVESTMENT DECISIONS?

        You make your own investment decisions. When you enroll in the
        Plan you may elect the percentage of your Account you want
        invested in each investment fund.  The Company 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-
        800-776-4015 and speaking with a participant services
        representative (or if you are hearing impaired, telephone 1-800-
        772-6009).  If you need additional information regarding the
        investment alternatives, or if you have any questions about your
        ERISA rights, you may contact: Bay State Gas Company, Benefits
        Committee, 300 Friberg Parkway, Westborough, Massachusetts 01581.

        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.  

        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 from
        period to period.

                                      9



        If you do not specify an investment fund or funds for the
        investment of your contributions, your contributions will be
        invested in a default investment fund specified by the
        Administrator.  The Administrator may change the designation of
        the default investment fund from time to time.

        The Plan is intended to be a participant directed individual
        account plan as described in Section 404(c) of ERISA and the
        regulations found in 29 C.F.R. Section 2550.404c-1.  Accordingly,
        fiduciaries of the Plan may be relieved of liability for any
        losses which are the direct and necessary result of investment
        instructions given by a participant or beneficiary.

        INVESTMENT IN COMPANY STOCK FUND

        The investment funds include a Company Stock Fund, which invests
        in NIPSCO Common Shares.  Previous investments in Bay State Gas
        Company common stock prior to the merger of Bay State Gas Company
        into a wholly-owned subsidiary of NIPSCO have been converted into
        Common Shares.  For liquidity purposes, a portion of the Company
        Stock Fund will also be invested in money market type assets.

        INVESTMENT FUNDS

        The value of Accounts invested in an investment fund other than
        the Common Stock Fund will be net of any investment manager fees
        that may be charged with respect to that particular fund.  The
        prospectus for each fund describes the fees and expenses
        associated with investing in that fund.  You will not be charged
        any fees or expenses with respect to investments in the Common
        Stock Fund.

        Purchases of Common Shares will normally be made as soon as
        practicable after the receipt by the Trustee of contributions
        which are to be invested in the Common Stock Fund.  Purchases or
        sales of Common Shares will also normally be made as soon as
        practicable after the receipt of an election by you to transfer
        amounts to or from the Common Stock Fund.  Each such purchase or
        sale will be made at the market price for Common Shares on the
        New York Stock Exchange at the time of such purchase or sale.

        You may upon request obtain additional information about each
        Investment Fund (e.g., each Fund's operating expenses, the
        prospectus and financial statements of each Fund and a list of
        assets comprising each Fund).  If you need additional information
        regarding the investment alternatives, or if you have any
        questions about your ERISA rights, you may contact: Bay State Gas
        Company, Benefits Committee, 300 Friberg Parkway, Westborough,
        Massachusetts 01581.

        HOW MAY I OBTAIN INVESTMENT FUND PERFORMANCE INFORMATION?

        You may obtain recent investment fund performance information by
        telephoning 1-800-776-4015 (or if you are hearing impaired,
        telephone 1-800-772-6009).

        HOW MAY I CHANGE MY INVESTMENT INSTRUCTIONS AND WHEN DO MY NEW
        INVESTMENT INSTRUCTIONS TAKE EFFECT?

        You may change your investment instructions for future
        contributions to your Account, for all or any portion of your
        existing Account balance, or for both, at any time.  You may make
        10 investment changes each year at no charge.  Your Account will
        be charged a fee for each additional change.  Currently, this fee
        is $10.00 and may be changed from time to time.  You will see
        these fees on your quarterly statement.

        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 instruction change will
        be sent within five business days after you make the change by
        telephone.

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

        INFORMATION REGARDING VOTING AND TENDERING COMPANY SHARES

        You will be entitled to instruct the Plan Trustee as to the
        voting or tendering of any whole and fractional shares of Company
        Shares held on your behalf in the Company Stock Fund.  The
        Company 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 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


                                     12



        officers or employees of the Company, except to the extent
        required by law.

        If you do not instruct the Trustee with regard to a shareholder
        vote or tender decision, your Common 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 the Company'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 1-800-776-4015 (or if you are hearing impaired,
        telephone 1-800-772-6009).

        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 Administra-
        tor, 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 circum-
        stances.

        The interest rate may be changed from time to time.  You may
        obtain information about the current interest rate by telephoning
        1-800-776-4015 (or if you are hearing impaired, telephone 1-800-
        772-6009).



                                     13



        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 1-800-776-4015 (or if you are hearing
        impaired, telephone 1-800-772-6009).

        Loan payments credited to your Account are invested in accordance
        with your current investment instructions for future contribu-
        tions 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
        the Company terminate for any reason.  Your outstanding loan
        balance is due upon the earlier of the date you request a
        distribution from your Account or 90 days after you terminate
        employment with the Company.  If you do not repay your loan
        balance before you request a distribution from your Account or
        within 90 days from your termination of employment, the
        Administrator will send you a written notice of default and a
        demand for past due amounts.  You have 30 days from receipt of
        the written notice of default in which to repay the remaining
        loan balance before the default becomes final.  Upon default, 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 by the Plan
        Committee.



                                     14



        A loan is treated as in default if scheduled loan payments are
        more than 90 days late.  You will have 30 days from the time you
        receive written notice of a default and demand for past due
        amounts to correct 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.

        WHAT HAPPENS TO MY LOAN IF I FILE FOR BANKRUPTCY?

        Under federal law, the Plan is generally not allowed to accept
        your loan repayments while you are in bankruptcy.  Once your
        bankruptcy is discharged, if your loan is not in default you may
        restart you loan payments.  A loan is treated as in default if
        scheduled loan payments are not made for more than 90 days.  You
        will have 30 days from the time you receive written notice of a
        default and demand for past due amounts to correct the default
        before it becomes final.  If your bankruptcy is not discharged
        within this period of time, your loan will be in default.  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. 

        ARE THERE ANY LOAN FEES?

        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.

        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.

                                     15



        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 and after attainment of age 70-1/2 (refer to Section
        entitled DISTRIBUTIONS AFTER YOU TERMINATE EMPLOYMENT WITH THE
        COMPANY OR AFTER YOU ATTAIN AGE 70-1/2).  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 the start of the first Plan Year
             beginning 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.

             *    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 the Company), 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

                                     16



             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.

        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 is 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, except for hardship withdrawals,
        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

                                     17



        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

   DISTRIBUTIONS AFTER YOU TERMINATE EMPLOYMENT WITH THE COMPANY OR AFTER
   YOU ATTAIN AGE 70-1/2

        WHAT ARE MY DISTRIBUTION PAYMENT OPTIONS?

        If your vested Account balance is $5,000 or less, and if your
        vested Account balance at the time of any prior in-service
        withdrawal or distribution did not exceed $5,000, your
        distribution payment options are limited to a single lump sum. 
        Otherwise, you may choose to have your vested Account balance
        distributed as follows:

        *    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 Shares 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

                                     18



        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 if your vested
        Account balance at the time of any prior in-service withdrawal or
        distribution did not exceed $5,000, if 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 at any time following your termination of
        employment with the Company on or before age 65.  However, if
        your vested Account balance is $5,000 or less, and if at the time
        of any prior in-service withdrawal or distribution your vested
        Account balance did not exceed $5,000, you should request a
        distribution of your vested Account balance at the time you
        terminate employment with the Company or shortly thereafter.  If
        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.  Mandatory 20% federal tax withholding will apply
        as described above.

        The law requires that you start taking distributions from your
        Account by April 1 of the calendar year following the later of
        either: (1) the calendar year in which you reach age 70-1/2, or
        (2) the calendar year in which you retire.  As a result, you are
        not required to start taking distributions by April 1 of the
        calendar year in which you reach age 70-1/2 if you are still
        working for the Company at that time. 

        If you are eligible and choose to defer distribution of your
        Account after you terminate employment with the Company, 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.




                                     19



        WHAT HAPPENS WHEN I REQUEST A DISTRIBUTION AFTER I TERMINATE OR
        AFTER I ATTAIN AGE 70-1/2?

        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
        Shares 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 the
        Company or a distribution after attainment of age 70-1/2, 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 bene-
        ficiary(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 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 Culture Develop-
        ment 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, complete

                                     20



        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 Culture Development.

        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 the Company
   -----------------------------

        WHEN CAN I RESUME MY PARTICIPATION?

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

   Federal Tax Consequences of Participation in the Plan
   -----------------------------------------------------

   The Plan is operated as a qualified plan under Sections 401(a) and
   401(k) of the Internal Revenue Code.  As a result, the amount of your
   pay which you elect to defer under the Plan through Employee Pre-Tax
   contributions and your Rollover contributions and Employer Match
   contributions and any earnings on, or appreciation of, your Account
   balance are not subject to Federal income taxes until such amounts are
   withdrawn or distributed to you or your beneficiary.  The amount of
   your Employee Pre-Tax contributions will, however, be included in your
   income in the year in which such amounts are earned for purposes of
   Social Security taxes.  Distributions and withdrawals generally become
   taxable in the year in which you receive them.

                                     21



   A distribution or withdrawal may be rolled over to a qualified
   retirement plan of another employer or to an individual retirement
   account or individual retirement annuity ("IRA") if the distribution
   is an "eligible rollover distribution" as defined in the Internal
   Revenue Code.  In such event, the amount rolled over and earnings
   thereon are not subject to income tax until subsequently distributed
   to you or your beneficiary.  Any amount of an "eligible rollover
   distribution" that is not rolled over may be subject to a mandatory
   20% withholding requirement (see "Income Tax Withholding" below). 

   If a lump sum distribution includes Common Shares, the excess, if any,
   of the fair market value of such Common Shares over the cost of the
   Common Shares to the Trustee is not subject to federal income tax at
   the time of distribution but generally will be subject to federal
   income tax when such Common Shares are subsequently sold.  To the
   extent provided by the Internal Revenue Code, you may elect not to
   defer the tax on net unrealized appreciation in Common Shares until
   the year of disposition of such Common Shares, thus subjecting the
   entire distribution to federal income tax at the time of distribution.

   An additional 10% excise tax will be imposed on any distribution or
   withdrawal received by you before you reach age 59 1/2 unless such
   distribution or withdrawal is (i) rolled over to another qualified
   plan or an IRA, (ii) made to a beneficiary after your death, (iii)
   made on account of your retirement due to disability (as defined in
   the Plan), (iv) made after separation from service after attainment of
   age 55, (v) made to you for payment of medical expenses that could be
   deducted on your tax return or (vi) made to an alternate payee
   pursuant to a qualified domestic relations order.

   Amounts that are included in taxable income may qualify for 5-year
   forward averaging tax treatment if you receive the amount in a lump
   sum distribution prior to January 1, 2000 but after you reach age 59
   1/2 and you actively participated in the Plan for at least five years
   prior to the year in which the lump sum is distributed to you.  Under
   a transitional rule, if you reached age 50 before January 1, 1986, you
   may make one election, without regard to the age 59 1/2 requirement,
   to use either 5-year forward averaging (using current tax rates) or
   10-year forward averaging (using the 1986 tax rates) with respect to
   the lump sum distribution, if otherwise eligible.  Five year forward
   averaging will not be available for distributions received on or after
   January 1, 2000.

   Employee Pre-Tax and Employer Match contributions made to the Plan by
   the Company on your behalf are deductible by the Company in the year
   in which the contributions are made.

   The rules governing the Federal income taxation of a distribution are
   complex and are subject to change.  Accordingly, you should seek the
   advice of a personal tax advisor in connection with a distribution.




                                     22



   Income Tax Withholding
   ----------------------

   Most Plan distributions and withdrawals are subject to mandatory
   federal income tax withholding.  The Trustee is required to withhold
   20% of any "eligible rollover distribution", unless you elect to have
   the Trustee make a direct rollover of such distribution into another
   employer's qualified retirement plan that accepts rollovers or to an
   individual retirement account or an individual retirement annuity.  A
   distribution or withdrawal is not an "eligible rollover distribution",
   and thus may not be rolled over, if it is (i) a series of
   substantially equal periodic installments over more than ten years, or
   over your life expectancy or the joint life expectancies of you and
   your beneficiary, (ii) a distribution of after-tax contributions,
   (iii) a required distribution due to attaining age 70-1/2 (or if
   later, due to retiring) or (iv) a distribution made to a nonspousal
   beneficiary.  If you request a distribution from the Common Stock Fund
   in the form of Common Shares rather than cash, the portion of your
   Account in the Common Stock Fund will not be liquidated to pay the
   withholding tax; however, the applicable taxes will be withheld from
   any cash portion of the distribution.

   A distribution or withdrawal that is not an "eligible rollover
   distribution" is subject to voluntary federal income tax withholding,
   which means that you can request that no withholding tax be deducted
   from your distribution.

   Future of the Plan
   ------------------

   The Company intends for the Plan to be a permanent part of your total
   benefits program.  However, the Company reserves the right to
   terminate the Plan at any time.  If the Plan is terminated all
   Accounts will become fully vested, if not otherwise fully vested, and
   payable as determined by the Plan Administrator.

   The Company 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 fully funded 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 Company is the Plan Administrator.  The Company may appoint
        an administrative committee and delegate to it all or part of its
        duties to oversee the Plan's operations.  As a Plan fiduciary,
        the Company 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.

        AGENT FOR SERVICE OF LEGAL PROCESS

        Service of legal process may be made upon the Company, as Plan
        Administrator, or Plan Trustee 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 the Company makes a
        minimum contribution to all eligible employees.







                                     24



   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 the
        Company.  The assets of the trust fund are not commingled with
        Company assets.  Generally, no part of the trust fund can be
        attached by creditors of any Plan participant or of the Company. 
        Assets of the trust fund are held exclusively to pay Plan
        benefits and expenses, and cannot revert to or be paid to the
        Company, 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

        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.  The administrative fee
        may be changed from time to time.  You will see these fees on
        your quarterly statement.  You may obtain information about the
        current administrative fee by telephoning 1-800-776-4015 and
        speaking with a participant services representative (or if you
        are hearing impaired, telephone 1-800-772-6009).

        You will also pay any special fees related to your own Account,
        such as loan fees, fees for installment payments and fees for
        change of your investment instructions more than 10 times per
        year.  You will see these fees on your quarterly statement.

        CLAIM REVIEW PROCEDURES

        As the Plan Administrator, the Company 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 Culture Development. 
        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 Company to
        respond:



                                                               25



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

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


              The Company 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
        Company 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
        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 the Company.

        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, as amended ("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;


                                     26



        *    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.

        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.



                                     27



        If you have any questions about your Plan, you should contact
        Culture Development.  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, listed in your

                               USE OF PROCEEDS

        Because the Plan is maintained in accordance with Section 401 ET
   SEQ. of the Internal Revenue Code of 1986, as amended, and the
   Employee Retirement Income Security Act of 1974, as amended, and
   because it is intended that all purchases of Common Shares will be
   made on the open market by the Trustee for the Plan, NIPSCO does not
   intend to have any net proceeds from the sale of the Common Shares
   offered under the terms of the Plan.

                            PLAN OF DISTRIBUTION

        The Common Shares being offered are offered pursuant to the Plan,

        NIPSCO's certificate of incorporation authorizes the issuance of
   400,000,000 Common Shares, without par value, of which 117,525,257

     ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The By-Laws of NIPSCO provide for indemnification by NIPSCO of
   each of its directors and officers to the fullest extent permitted by
   law for liability of such director or officer arising by reason of his
   or her status as a director or officer of NIPSCO or its subsidiaries. 
   Under NIPSCO's By-Laws as well as the Indiana Business Corporation Law
   (the "Indiana BCL"), NIPSCO is required to indemnify its directors and
   officers against expenses, judgments, decrees, fines, penalties and
   settlements actually and reasonably incurred by such person in
   connection with any action, suit or proceeding, whether civil,
   criminal, administrative or investigative, to which such person is a
   party by reason of his or her connection with NIPSCO, provided that
   such person acted in good faith and in a manner he or she reasonably
   believed to be in the best interest of NIPSCO, or, with respect to a
   criminal proceeding, has no reasonable cause to believe that his or
   her conduct was unlawful.

        The By-Laws of NIPSCO provide that, except where a director or
   officer is substantially and finally successful on the merits, NIPSCO
   may not indemnify a director or officer (unless ordered by a court)
   until after a determination has been made that indemnification of the
   director or officer is permissible because he or she met the
   applicable standards of conduct.  NIPSCO also may not advance expenses
   prior to the disposition of an action, suit or proceeding until: (a)
   the director or officer provides NIPSCO with a written affirmation of
   his or her good faith belief that he or she has met the applicable
   standards of conduct and an undertaking to repay the advance if it is
   ultimately determined that he or she did not meet the applicable
   standards of conduct, and (b) a determination has been made, that,
   based on the facts then known to those making the determination, the
   director or officer met the applicable standards of conduct.  The
   determination that a director or officer has met the applicable
   standards of conduct may be made by a majority vote of a quorum
   consisting of disinterested directors, a majority vote of a committee
   designated by the board of directors consisting of two or more



                                    II-1



   disinterested directors (only if a quorum of the board cannot be
   obtained), special legal counsel or a majority vote of disinterested
   shareholders.

        As authorized under NIPSCO's By-Laws and the Indiana BCL, NIPSCO
   and its subsidiaries have insurance which insures directors and
   officers for acts committed as such directors or officers which are
   determined not to be indemnifiable under NIPSCO's indemnity
   provisions.

        Insofar as indemnification for liabilities arising under the
   Securities Act of 1933 may be permitted to directors, officers and
   controlling persons of NIPSCO pursuant to the foregoing provisions, or
   otherwise, NIPSCO has 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 NIPSCO of expenses
   incurred or paid by a director, officer or controlling person of
   NIPSCO 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, NIPSCO 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.

   ITEM 16.  EXHIBITS.

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

   ITEM 17.  UNDERTAKINGS.

        (a)  NIPSCO hereby undertakes:

             (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;

                  (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 this
             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

                                    II-2



             high end of the estimated maximum offering range may be
             reflected in the form of prospectus filed with the
             Commission pursuant to Rule 242(b) if, in the aggregate, the
             changes in volume and price represent no more than a 20%
             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 this Registration Statement or any material change to
             such information in this Registration Statement;

             PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii)
             of this section do not apply if the registration statement
             is on Form S-3, Form S-8 or Form F-3, 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 NIPSCO pursuant to Section
             13 or Section 15(d) of the Exchange Act that are
             incorporated by reference in this Registration Statement.

             (2)  That, for the purpose of determining any liability
        under the Securities Act, 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.

        (b)  NIPSCO hereby undertakes that, for purposes of determining
   any liability under the Securities Act of 1933, each filing of
   NIPSCO's annual report pursuant to Section 13(a) or Section 15(d) of
   the Exchange Act (and, where applicable, each filing of an employee
   benefit plan's annual report pursuant to Section 15(d) of the Exchange
   Act) that is incorporated by reference in this 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.

        (c)  Insofar as indemnification for liabilities arising under the
   Securities Act may be permitted to directors, officers and controlling
   persons of NIPSCO pursuant to the foregoing provisions, or otherwise,
   NIPSCO has been advised that in the opinion of the Commission such
   indemnification is against public policy as expressed in the
   Securities Act and is, therefore, unenforceable. In the event that a
   claim for indemnification against such liabilities (other than the
   payment by NIPSCO of expenses incurred or paid by a director, officer
   or controlling person of NIPSCO in the successful defense of any

                                    II-3



   action, suit or proceeding) is asserted by such director, officer or
   controlling person in connection with the securities being registered,
   NIPSCO 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 Securities Act and will be
   governed by the final adjudication of such issue.
