Contract No. l387GAC with John Hancock Mutual Life Insurance
Company (the "Bargaining Unit Plan").

(the "Central Plan") to continue coverage for certain former
employees of Central Indiana Gas Company, a wholly owned
subsidiary of the Company which was dissolved on September 30,
1976.  In addition, effective January l, 1976 the Prior Plan was
amended and restated in its entirety (the "Indiana Gas Plan").

be known as "The Indiana Gas Company, Inc. Combined Non-
Bargaining Retirement Plan" (the "Plan"), the terms of which are
as herein contained.

    Effective as of October 1, 1997, Indiana Gas Company, Inc.
transferred sponsorship of the Plan to Indiana Energy, Inc.

    Effective as of July00000 1, 2000, the Plan's name is changed
to the Vectren Corporation Combined Non-Bargaining Retirement
Plan as a result of the consummation of the Agreement and Plan of
Merger, dated as of June 11, 1999 and among Indiana Energy, Inc.,
SIGCORP and Vectren Corporation (the "Vectren Merger").
Effective July 1, 2000, the Pension Plan for Salaried Employees
of Southern Indiana Gas and Electric Company (the "SIGECo Pension
Plan") is merged into, and has become a part of, this Plan.  This
Plan shall be deemed to be a continuation of the SIGECo Pension

Revenue Code of 1986, as amended, including all regulations
promulgated thereunder (the "Code") and of the Employee
Retirement Income Security Act of 1974, as amended, including all

shall be interpreted to comply with applicable requirements of
the Code and of the Act.

    Pursuant to Article X of the Plan, as last amended and
restated effective January 1, 1999, Vectren Corporation,

                            ARTICLE I
                              TITLE

    This Plan shall be known as the "Vectren Corporation Combined
Non-Bargaining Retirement Plan" (the "Plan").





                           ARTICLE II
                           DEFINITIONS

    As used herein and in the Trust Agreement, the following
words and phrases shall have the meanings specified below, unless
a different meaning is plainly required by the context:

    Section 2.01.  The term "Accrued Benefit  shall mean for the
period before January 1, 1999, as of any applicable date, and
shall be equal to the product of subsection (a) and subsection
(b) below:

     (a)  the Member's projected Monthly Retirement Income at his
          Normal Retirement Date calculated on the basis of the
          following assumptions:

          (i)   that the Member's Average Monthly Earnings at the
                date of calculation would have been his Average
                Monthly Earnings at his Normal Retirement Date;
                and

          (ii)  that his Credited Service would have continued
                uninterrupted until his Normal Retirement Date;

     (b)  a fraction, the numerator of which shall be the
          Member's Credited Service as of the date of calculation
          and the denominator of which shall be the Credited
          Service that the Member would have accumulated had he
          continued his employment with the Employers until his
          Normal Retirement Date without interruption of his
          Credited Service.

    The term "Accrued Benefit" shall mean for the period
beginning on and after January 1, 1999, as of any applicable
date, the Monthly Retirement Income determined in accordance with
the provisions of Article IV that the Member would be entitled to
receive commencing on his Normal Retirement Date based on his
Average Monthly Earnings and years of Credited Service through
the applicable date.

    Notwithstanding anything contained herein to the contrary, a
Member's Accrued Benefit shall under no circumstances be less
than his Accrued Benefit determined at December 31, 1998 under
the provisions of the Plan then in effect; provided, however,
that the Accrued Benefit of a Transitional IEI Member with at
least sixty (60) Points at December 31, 1998 shall, as of any
applicable date on or after January 1, 1999, be equal to the sum
of:

     (c)  an amount equal to what his Accrued Benefit would have
          been had the provisions of this Plan in effect on
          December 31, 1998 continued in effect, plus

     (d)  the Member's Cash Balance Benefit (as determined under
          Article IV).

Notwithstanding anything contained herein to the contrary, the
Accrued Benefit of a Member who was a participant in the SIGECo
Pension Plan on June 30, 2000 but who is not a Transitional
SIGECo Member should under no circumstances be less than his
Accrued Benefit determined at June 30, 2000 under the provisions
of the SIGECo Pension Plan then in effect.

Retirement Income Security Act of 1974 as now in effect or

             Interest  -  seven and one-half percent (7.5%) per
                          annum, compounded annually;

             Mortality -  1971 Group Annuity Table for Male and
                          Female lives, without projection.

     (b)  For the period beginning on August 1, 1983, the
          actuarial assumptions used by this Plan for purposes
          of converting life annuities to optional forms of
          payment (other than single lump sums) and for purposes
          of converting optional forms of payments (other than
          single lump sums) to a life annuity shall be as
          follows:

             Interest  -  seven and one-half percent (7.5%) per
                          annum, compounded annually;

             Mortality    1971 Group Annuity Table, using a
                          sixty percent (60%) male and forty
                          percent (40%) female assumption;

          provided, however, that, in accordance with the above
         stated actuarial assumptions, the factors used for
         computing a Member's benefits in the form of a joint
         and survivor annuity shall be as follows:







       Type of Joint    Base Factor    Adjustment Per Year of Age
       and Survivor                        Difference between the
          Benefit                      Member and His Beneficiary
     ----------------  -------------  --------------------------
            --               -                    --
                                
           100%             .844
          66 2/3%           .890                 .005
            50%             .915                 .004

     Adjustments for the age difference between the Member and his
     Beneficiary shall be subtracted from the base factor if the
     Beneficiary is younger than the Member and shall be added to the
     base factor if the Beneficiary is older than the Member.  Age
     differences shall be rounded up or down to the closest
     whole year.


    Notwithstanding the above, the interest rate used for
determining the Actuarial Equivalent of a lump sum payment or, if
applicable, converting a life annuity to a lump sum under
Section 5.06 shall be the Applicable Interest Rate in effect for
the November of the Plan Year immediately preceding the Plan Year
during which the determination is made and by using the
applicable mortality table (the "Applicable Mortality Table")
under Section 417(c)(3) of the Code and Treasury Regulation
Section 1.417(e)-1T(d)(2); provided, however, that for purposes
of converting the Prior Retirement Benefit to an Actuarial
Equivalent single sum value in accordance with Section 4.04, an
interest rate assumption of six percent (6%) shall be used.

the actuarial assumptions set forth in Section 2.03.

          compensation but specifically excluding any period
          for which Disability Payments are made under this
          Plan); and

     (c)  as a result of a back pay award which has been
          agreed to or made by an Employer, irrespective of
          mitigation of damages, to the extent that such hour
          has not been previously credited under subsection
          (a) or under subsection (b) above.


The number of Hours of Service to be credited on account of a
period of time during which no duties are performed (including
hours resulting from a back pay award) shall be determined as
follows:

     (d)  If the payment which is made or due is calculated on
          the basis of units of time, the number of Hours of
          Service to be credited shall be the number of
          regularly scheduled working hours included in the
          units of time on the basis of a regular work
          schedule; if an employee does not have a regular
          work schedule, the number of Hours of Service to be
          credited shall be calculated on the basis of an
          eight (8) hour work day.

     (e)  If the payment which is made or due is not
          calculated on the basis of units of time, the number
          of Hours of Service to be credited shall be
          calculated by dividing the amount of the payment by
          the Employee's most recent hourly rate of
          compensation before the period during which no
          duties were performed, determined as follows:

          (i)    If the Employee's compensation is determined
                 on the basis of an hourly rate, such hourly
                 rate shall be the employee's most recent
                 hourly rate of compensation.

          (ii)   If the Employee's compensation is determined
                 on the basis of a fixed rate for a specified
                 period of time other than hours, his hourly
                 rate of compensation shall be his most recent
                 rate of compensation for the specified period
                 of time, divided by the number of hours
                 regularly scheduled for the performance of
                 duties during such period of time; if an
                 employee does not have a regular work
                 schedule, his hourly rate of compensation
                 shall be calculated on the basis of an eight
                 (8) hour work day.

          (iii)  If the Employee's compensation is not
                 determined on the basis of a fixed rate for a
                 specified period of time, his hourly rate of
                 compensation shall be the lowest hourly rate
                 of compensation paid to employees in his job
                 classification or, if no employees in his job
                 classification have an hourly rate of
                 compensation, the minimum wage in effect
                 under Section 6(a)(l) of the Fair Labor
                 Standards Act of 1938, as amended.

In no event shall the application of the terms of subsection (d)
or subsection (e) above result in crediting an employee with a
number of Hours of Service during any computation period which is
greater than the number of hours regularly scheduled for the
performance of duties.  If an employee has no regular work
schedule, the number of Hours of Service to be credited to him
shall not exceed the number which would be credited calculated on
the basis of an eight (8) hour work day.

    No Employee shall be credited with more than five hundred and
one (501) Hours of Service as a result of the application of
subsection (d) or subsection (e) above for any single continuous
period during which he performs no duties, regardless of whether
such period extends beyond one (l) Plan Year or other applicable
computation period; provided, however, that the Hours of Service
credited pursuant to Section 4.08 shall not be so restricted.  In
no event shall any Employee be credited for any hour for which he
receives no compensation from the Employers, except as otherwise
provided in subsection (b) above.

    The Plan Year or other applicable computation period to which
Hours of Service shall be credited shall be determined as
follows:

     (f)  Except as hereinafter provided, Hours of Service
          credited in accordance with subsection (a) above
          shall be credited in the Plan Year or other
          applicable computation period in which the duties
          were performed.

     (g)  Except as hereinafter provided, Hours of Service
          credited in accordance with subsection (b) above
          shall be credited as follows:  if calculated on the
          basis of units of time, to the Plan Year or Plan
          Years or other applicable computation periods in
          which the period during which no duties are
          performed occurs, beginning with the first (1st)
          unit of time to which the payment relates;
          otherwise, to the Plan Year or other applicable
          computation period in which the period during which
          no duties are performed occurs; provided, however,
          that if the period during which no duties are
          performed extends beyond one (l) Plan Year or other
          applicable computation period, such Hours of
          Service shall be allocated between not more than
          the first (1st) two (2) Plan Years or other
          applicable computation periods on any reasonable
          basis consistently applied.

     (h)  Except as hereinafter provided, Hours of Service
          credited in accordance with subsection (c) above
          shall be credited to the Plan Year or other
          applicable computation period to which the award or
          agreement for back pay pertains rather than to the
          Plan Year or other applicable computation period in
          which the award, agreement or payment is made.

     (i)  Hours of Service to be credited to an Employee in
          connection with a period of no more than thirty-one
          (31) calendar days which extends beyond one (l)
          Plan Year or other applicable computation period
          may be credited to the first (1st) or to the second
          (2nd) Plan Year or to any other applicable
          computation period; provided, however, that such
          crediting is done on a reasonable and
          nondiscriminatory basis.

    Nothing in this Section 2.35 shall be construed to alter,
amend, modify, invalidate, impair or supersede any law of the
United States or any rule or regulation issued under any such
law.  The nature and extent of any credit for Hours of Service
under this Section 2.35 shall be determined under the Act.

    Solely for purposes of determining whether a Break in Service
for participation and vesting purposes has occurred in any
computation period, an employee who is absent from work for
maternity or paternity reasons on or after January 1, 1985 shall
receive credit for the Hours of Service which would otherwise
have been credited to that employee but for such absence or, in
any case in which such Hours of Service cannot be determined,
eight (8) Hours of Service per each regularly scheduled workday
of such absence.  For purposes of this paragraph, an absence from
work for maternity or paternity reasons means an absence on or
after January 1, 1985 by reason of the pregnancy of the employee,
by reason of the birth of a child of the employee, by reason of
the placement of a child with the employee in connection with the
adoption of that child by the employee, or for purposes of caring
for that child for a period beginning immediately following such
birth or placement. The Hours of Service credited under this
paragraph shall be credited in the computation period in which
the absence begins if the crediting is necessary to prevent a
Break in Service in that computation period or, in all other
cases, in the following computation period.  To the extent
required under the Family and Medical Leave Act of 1993 ("FMLA")
and solely for purposes of determining whether a Break in Service
for participation and vesting purposes has occurred in any
computation period, an individual who is absent from work on
unpaid leave under the FMLA on or after August 5, 1993 shall
receive credit for the Hours of Service which would otherwise
have been credited to such individual but for such absence or, in
any case in which such Hours of Service cannot be determined,
eight (8) Hours of Service per each regularly scheduled work day
of such absence.  For purposes of determining a participant's
service and credited service during an FMLA leave, a participant
shall receive credit for the Hours of Service which would
otherwise have been credited to such individual but for such
absence or, in the case in which such hours of work cannot be
determined, eight (8) Hours of Service per each regularly
scheduled work day of such absence in determining his eligibility
for benefits, the vesting of his benefits and the amount of his
benefits under this Plan; provided, however, that if the FMLA
leave is unpaid, such credit shall only be granted to the extent
the employee completes an Hour of Service for a participating and
affiliated employer after the leave.

    Section 2.36.  The term "Indiana Gas Plan " shall mean the
Retirement Plan for Non-Bargaining Unit Employees of Indiana Gas
Company, Inc. as in effect on December 31, 1981.

    Section 2.37.  The term "Investment Committee " shall mean
the Investment Committee as provided in Article XV.

    Section 2.38.  The term "Late Retirement Date " shall mean
the first (1st) calendar day of any month subsequent to a

with the Controlled Group Entities for any reason other than his
death.

    Section 2.39.  The term "Member " shall mean any Employee who
has become a Member as provided in Article III.

    Section 2.40.  The term "Monthly Earnings " shall mean a
Member's cash compensation from the Employers (exclusive of
relocation allowances and other reimbursement allowances) during
the calendar year preceding the Anniversary Date, divided by
twelve (12); provided, however, that with respect to any Employee
who was a Member before July 1, 2000 and who was employed by
Indiana Energy, Inc. or one of its subsidiaries before April 1,
2000, Monthly Earnings shall be exclusive of all forms of
extraordinary earnings such as overtime, bonuses, incentive pay,
education advancements, relocation expenses, severance expenses
and unpaid time off for the period from July 1, 2000 through
December 31, 2000.  The term "Monthly Earnings" shall also
include Controlled Group Entities' contributions made pursuant to
a salary reduction agreement which are not included in the gross
income of the Employee under Section 125, Section 402(a)(8),
Section 402(h) or Section 403(b) of the Code and any voluntary
salary reduction made by a Member under any non-qualified
deferred compensation plan maintained by the Controlled Group
Entities.  Monthly Earnings shall be determined on each
Anniversary Date and shall remain in effect until the next
Anniversary Date.  For Plan Years beginning after December 31,
1988 and before January 1, 1994, Monthly Earnings shall in all
cases be limited to two hundred thousand dollars ($200,000) in
any Plan Year and shall be determined in accordance with Section
414(s) of the Code; provided, however, that this dollar
limitation shall be automatically adjusted in accordance with
Section 401(a)(17) of the Code without the necessity of any
amendment to this Plan.  In addition to other applicable
limitations set forth in this Plan and notwithstanding any other
provision of this Plan to the contrary, for Plan Years beginning
on or after January 1, 1994, the Monthly Earnings of each
Employee taken into account under this Plan in any Plan Year
shall not exceed the OBRA '93 Annual Compensation Limit.  The
OBRA '93 Annual Compensation Limit is one hundred and fifty
thousand dollars ($150,000), as adjusted by the Commissioner for
increases in the cost of living in accordance with Section
401(a)(17)(B) of the Code.  The cost-of-living adjustment in
effect for a Plan Year applies to any period, not exceeding
twelve (12) months, over which compensation is determined
(determination period) beginning in such calendar year.  If a
determination period consists of fewer than twelve (12) months,
the OBRA '93 Annual Compensation Limit will be multiplied by a
fraction, the numerator of which is the number of months in the
determination period, and the denominator of which is twelve
(12).  For Plan Years beginning on or after February 1, 1994, any
reference in this Plan to the limitation under Section 401(a)(17)
of the Code shall mean the OBRA '93 Annual Compensation Limit set
forth in this provision.  If compensation for any prior
determination period is taken into account in determining an
Employee's benefits accruing in the current Plan Year, the
compensation for that prior determination period is subject to
the OBRA '93 annual compensation limit in effect for that prior
determination period.  For this purpose but effective January 1,
1994, for determination periods beginning before the first day of
the first Plan Year beginning on or after January 1, 1994, the
OBRA '93 Annual Compensation Limit is one hundred and fifty
thousand dollars ($150,000).

employed by Indiana Energy, Inc. or one of its subsidiaries on
December 31, 1998 and if the Member's Points on December 31, 1998
are greater than forty-nine (49) and less than sixty (60):

          50-54                         3.5%

nearest whole point, with the Member receiving one (1) Point for

          election;

     (b)  the election designates a specific alternate
          Beneficiary, including any class of Beneficiaries
          or any contingent Beneficiaries, which may not be

          expressly permits designations by the Member
          without any further Spousal consent);

     (c)  the Spouse's consent acknowledges the effect of the
          election; and

     (d)  the Spouse's consent is witnessed by a Plan

Additionally, a Member's waiver of the Qualified Joint and
Survivor Annuity shall not be effective unless the election
designates a form of benefit payment which may not be changed
without Spousal consent (or the Spouse expressly permits
designations by the Member without any further Spousal consent).
If it is established to the satisfaction of a Plan representative
that such written consent may not be obtained because there is no
Spouse or the Spouse cannot be located, a waiver shall be deemed
a qualified election.  Any consent by a Spouse obtained under
this Section (or establishment that the consent of a Spouse may
not be obtained) shall be effective only with respect to that
Spouse.  A consent that permits designations by the Member
without any requirement of further consent by his Spouse shall
acknowledge that the Spouse has the right to limit consent to a

number of revocations shall not be limited.

                 Section 105(a) and Section 115(h) of the Code
                 but only to the extent that these amounts are
                 includible in the gross income of that Member;

          (iv)   amounts paid or reimbursed by the Controlled
                 Group Entities for moving expenses incurred by
                 that Member, but only to the extent that these
                 amounts are not deductible by that Member
                 under Section 217 of the Code;

          (v)    amounts included in that Member's gross income
                 by reason of an election under Section 83(b)
                 of the Code; and
          (vi)   for Plan Years beginning after December 31,

                 Code.

     (b)  not include:

          (i)    notwithstanding subsection (a)(i) above and
                 solely with respect to Plan Years beginning
                 before January 1, 1998, there shall be
                 excluded from Section 415 Compensation amounts
                 contributed by the Controlled Group Entities
                 to a tax qualified cash or deferred plan under
                 Section 401(k) of the Code;

          (ii)   except as otherwise provided in Subsection
                 (a)(v) above, other contributions made by the
                 Controlled Group Entities to a plan of
                 deferred compensation to the extent that,
                 before the application of the Section 415 of
                 the Code limitations to that plan, the
                 contributions are not includible in the gross
                 income of that Member for the taxable year in
                 which contributed.  In addition, Controlled
                 Group Entities contributions made on behalf of
                 a Member to a simplified employee pension plan
                 described in Section 408(k) of the Code shall
                 not be considered as Section 415 Compensation
                 for the Plan Year in which contributed.
                 Additionally, any distributions to a Member
                 from a plan of deferred compensation shall not
                 be considered as Section 415 Compensation,
                 regardless of whether such amounts are
                 includible in the gross income of that Member
                 when distributed.  However, any amounts
                 received by a Member pursuant to an unfunded
                 nonqualified plan shall be considered as
                 Section 415 Compensation in the Plan Year in
                 which such amounts are includible in the gross
                 income of that Member;

          (iii)  except as otherwise provided in Subsection
                 (a)(v) above, amounts which receive special
                 federal income tax benefits, such as premiums
                 for group term life insurance (but only to the
                 extent that the premiums are not includible in
                 the gross income of that Member); and

          (iv)   except as otherwise provided in Subsection
                 (a)(v) above, amounts realized when restricted
                 property becomes taxable under Section 83 of
                 the Code because the property becomes freely
                 transferable or not subject to a substantial
                 risk of forfeiture.

Notwithstanding anything in this Section to the contrary, for
Plan Years beginning on or after January 1, 1998, Section 415
Compensation shall include any elective deferral (as defined in
Section 402(g) of the Code) and any amount contributed or
deferred at the election of the Participant that is not
includible in that Participant's gross income by reason of
Section 125 or Section 457 of the Code.

    Section 2.56.  The term "SIGECo Pension Plan " shall mean the
Pension Plan for Salaried Employees of Southern Indiana Gas and

                           MEMBERSHIP


    Section 3.01.  Initial Membership and Upon Reemployment. Each
Employee who was a participant in this Plan as of December 31,
1988 remains a Member of this Plan without further action on his
part.  On any Participation Date commencing with January 1, 1989
an Employee who is not yet a Member shall become a Member;
provided, however, that prior to or as of such Participation Date
he has fulfilled the following requirements:

     (a)  he has reached at least Attained Age twenty-one
          (21), and

     (b)  he is an Employee;


provided, however, that any Employee who was a participant in the
SIGECo Pension Plan on June 30, 2000 shall become a Member in
this Plan on July 1, 2000.

    A terminated Member who later resumes his employment with an
Employer shall become a Member immediately upon his return to the
status of an Employee.  An Employee whose employment with the
Employers is terminated before he becomes a Member and who later
resumes his employment with an Employer shall become a Member on
the later of:

     (c)  his return to the status of an Employee, or

     (d)  the date he fulfills the requirements of this
          Section 3.01, taking into account all prior
          periods of his employment with the Employers.

    Each Employee shall be furnished a summary of this Plan by
the Plan Administrator when he becomes a Member as required by
the Act.

    Section 3.02.  Change in Status.  If a Member hereunder
ceases to be an Employee due to a change in his employment
status, while remaining an employee of an Employer or of a
Controlled Group Entity, he shall cease to accrue Credited
Service as of the date of such change in status and shall become
a limited Member hereunder until such time as he again becomes an
Employee.  If such a limited Member does not again become an
Employee prior to his termination of employment with the
Controlled Group Entities, the amount, if any, of the benefits to
which he is entitled hereunder shall be determined based on his
Credited Service and his Average Monthly Earnings (as of the date
of his change of status), his Attained Age (at his date of
termination of employment), his Years of Service (including his
period as a limited Member) and his reason for terminating his
employment with the Controlled Group Entities. If an employee who
is not a Member becomes an Employee due to a change in his
employment status or due to the adoption of this Plan by a
Controlled Group Entity in accordance with Section 16.01, he
shall become eligible for membership in this Plan immediately;
provided, however, that he would have become a Member if he had
met the definition of Employee as of his most recent date of hire
by an Employer or by a Controlled Group Entity.  If any such
Employee becomes a Member, he shall have Credited Service for all
prior periods of his employment with the Employers, but the
provisions of Section 5.09 and Section 9.04 shall be specifically
applicable; provided, however, that except as provided under
Section 2.64(g), a Member shall not have any Credited Service for
any period of employment with an Employer before the date on
which that Employer became a participating Employer in this Plan.

    Section 3.03.  Plan Binding.  Upon becoming a Member, an
Employee and his Spouse or other Beneficiary and any and all
other persons who might thereafter claim benefits under this Plan
on his behalf shall be bound then and thereafter by the terms of
this Plan and of the Trust Agreement, including all amendments
thereto made in the manner authorized by this Plan.

    Section 3.04.  Rehire after Military Service.  The provisions
relating to qualified retirement plans which are set forth in the
Uniformed Services Employment and Reemployment Rights Act of 1994
("USERRA") are hereby incorporated into, and made a part of, this
Plan by reference.  The Investment Committee shall apply the
provisions of the USERRA with respect to any Participant who is
reemployed after completing covered military service in a manner
consistent with the USERRA and all other applicable law and
regulations.





                           ARTICLE IV

                    MONTHLY RETIREMENT INCOME


    Section 4.01.  General Restrictions and Liability.  Monthly
Retirement Income payable under the terms of this Article IV
shall be subject to the restrictions and limitations of Article

the Trustee only by or at the written direction of the Plan

the Employers, the Plan Administrator nor the Trustee shall be
under any obligation to pay any Monthly Retirement Income other

Qualified Joint and Survivor Annuity and an unmarried Member's
vested Accrued Benefit and Cash Balance Benefit shall be paid in
the basic form which is monthly income commencing at the Annuity
Starting Date and continuing for that Member's lifetime.

    The Plan Administrator shall provide each Member no less than
thirty (30) calendar days and no more than ninety (90) calendar

of:

     (a)  the terms and conditions of the Qualified Joint and
          Survivor Annuity;

     (b)  the Member's right to make and the effect of an
          election to waive the Qualified Joint and Survivor
          Annuity form of benefit;

     (c)  the rights of the Member's Spouse;

     (d)  the right to make and the effect of a revocation of
          a previous election to waive the Qualified Joint and
          Survivor Annuity; and

     (e)  the relative values of the various optional forms of
          benefits under this Plan;

provided, however, that a Member could and, if applicable, the

requirement as long as the Annuity Starting Date does not
commence earlier than seven (7) calendar days after the date the
written explanation described above is delivered and the written
explanation discloses to the Member that the Member and Spouse
have at least thirty (30) days to make their election.

    Prior to a Member's Annuity Starting Date, the Member may
elect in a written application provided by the Plan Administrator
to receive his Monthly Retirement Income in any of the optional

4.02 may be revoked and a new election may be made at any time
prior to the commencement of benefit payments; provided, however,
that any new election by a married Member shall be a Qualified
Election.  Once benefit payments have commenced, no further
revocation or change of election shall be permitted.

    The optional forms of distribution of benefits shall include

          of the amount (as elected by the Member) to a
          Beneficiary designated in writing by the Member;
          provided, however, that if the Beneficiary is
          other than that Member's Spouse, the Actuarial
          Value of the payments expected to be made to that
          Member shall exceed fifty percent (50%) of the
          Actuarial Value of the total payments expected to
          be made to that Member and to his Beneficiary.
          If the Beneficiary named by the Member dies prior
          to the Member's Early, Normal, Late or Special
          Retirement Date or prior to the date specified in
          Section 5.01, the election shall be void and

          monthly income payable in the life annuity form
          with guaranteed minimum number of monthly
          payments of sixty (60) or one hundred and twenty
          (120); provided, however, that upon the death of
          the Member before full payment of the guaranteed
          minimum number of payments, the Plan
          Administrator shall continue such monthly
          payments to the Member's Beneficiary for the
          balance of the guaranteed period; provided,
          further, that the number of guaranteed monthly
          payments shall not extend for a period greater
          than the joint life expectancy of the Member and
          his spouse, if any (with such life expectancy
          determined as of the date that benefit payments
          commence in accordance with regulations under the
          Code).

     (i)  A Member or former Member may elect to have his
          Cash Balance Benefit paid in the form of an

          Retirement Date, he shall be entitled to retire and
          to receive a Monthly Retirement Income in an amount
          calculated and certified in writing to the Trustee
          by the Plan Administrator.  The amount of a
          Member's Monthly Retirement Income under the basic
          form and payable on his Normal Retirement Date
          shall be equal to the sum of:

          (i)   fifty-five one hundredths percent (.55%) of
                the Member's Average Monthly Earnings
                multiplied by the Member's years of Credited
                Service, plus

          (ii)  fifty-three one hundredths percent (.53%) of
                the Member's Average Monthly Earnings in

                years);

          provided, however, that in determining a Member's
         covered compensation the average (without indexing),
         rounded in accordance with tables approved by the
         Commissioner of Internal Revenue, of the taxable
         wage bases in effect for each calendar year during
         the thirty-five (35) year period ending with the
         last day of the calendar year in which the Member
         attains (or will attain) the Social Security

         compensation of a Member whose employment with the
         Controlled Group Entities is terminated before
         attaining the Social Security retirement age shall
         be based on the Member's covered compensation in
         effect at the beginning of the calendar year for
         which the determination is being made assuming no
         change in the taxable wage base in subsequent
         calendar years.  The term "Social Security

         1938 and December 31, 1954 and 67 for participants
         born on or after January 1, 1955), except that such
         Section shall be applied without regard to the age
         increase factor and as if the early retirement age
         under Section 216(1)(2) of such Act were sixty-two
         (62).

     (b)  Not Employed on January 1, 1999, but Reemployed

          be entitled to a monthly pension equal to his Prior
          Retirement Benefit and also to a Cash Balance
          Benefit calculated in accordance with Section 4.04.
          Any former Member whose rights and interests in the
          Plan are vested, who is not employed by an Employer
          on January 1, 1999, but who is later reemployed and
          credited with at least one (1) Hour of Service

                their June 30, 2000 Accrued Benefit converted
                into a Cash Balance Benefit.  The
                Transitional SIGECo Members shall continue to
                accrue benefits under this Plan in accordance
                with the formula in effect under the SIGECo
                Pension Plan in effect on June 30, 2000.  The
                Monthly Retirement Income payable to each
                such Transitional SIGECo Member shall be
                based on his Monthly Earnings and Years of
                Service through the date of his termination
                of employment.

In no event shall the Accrued Benefit under this Plan of any
Member be less than his Accrued Benefit determined as of December
31, 1998.

    Section 4.04.  Cash Balance Benefit.  The Cash Balance
Benefit for each Member who retires on his Normal Retirement Date
shall be a single life annuity commencing at the Member's Normal
Retirement Date that is the Actuarial Equivalent of the Member's
Cash Balance Account balance as of his Annuity Starting Date.

    The Cash Balance Account of each Member who has completed one
thousand (1,000) Hours of Service in a Plan Year or who died or
retired during the Plan Year after meeting the Plan requirements
for early or normal retirement shall be credited, as of the last
day of such Plan Year (or as of the last day of his last pay
period in which his termination occurs if his employment with the
Employers terminates during the Plan Year on account of death or
retirement on or after either his Early Retirement Date or Normal
Retirement Date), with Pay Credits earned by that Member with
respect to Plan Year Compensation received during that Plan Year.
Effective July 1, 2000 or, with respect to any Member who was
employed by Indiana Energy, Inc. or one (1) of its subsidiaries
before April 1, 2000, effective January 1, 2001, the Cash Balance
Account of a Member shall also be credited each Plan Year with an
amount equal to three hundred and ten dollars ($310.00);
provided, however, that if the Member is not employed by an
Employer for the entire Plan Year, the amount credited shall be
pro-rated based on the number of months (including portions
thereof) during which the Member was employed; provided, further,
that the maximum amount credited for the 2000 Plan Year shall be
equal to one hundred and fifty-five dollars ($155) due to the
July 1, 2000 effective date; provided, further, that Members who
were employed by Southern Indiana Gas & Electric Company on
July 1, 1998 and were at least age fifty (50) on July 1, 1998 or
who were employed by Indiana Energy or one of its subsidiaries on
January 1, 2001 and were at least age fifty (50) and completed at
least five (5) Years of Service on January 1, 2001 shall not be
eligible for the additional three hundred and ten dollar ($310)
credit.

    Except for certain Transitional IEI Members and Transitional
SIGECo Members, each Member (with an Accrued Benefit but without
a Cash Balance Benefit) shall be credited with an initial Cash
Balance Account balance determined in the following manner.

     (a)  IEI Members.  Each Member who was employed by
          Indiana Energy, Inc. or any of its subsidiaries
          before April 1, 2000, who does not incur a period
          of severance that includes January 1, 1999, who
          performs one Hour of Service as a Member after
          December 31, 1998 and who has not already begun
          receiving benefits under this Plan shall be
          credited, as of the first date he is credited
          with an Hour of Service as a Member after
          December 31, 1998, with an initial Cash Balance
          Account balance equal to the Actuarial Equivalent
          of his Prior Retirement Benefit; provided,
          however, that if a Transitional IEI Member has
          completed at least sixty (60) Points on
          December 31, 1998, the Member shall not have his
          Prior Retirement Benefit converted to a Cash
          Balance Account.

     (b)  SIGECo Members.  Each Member who was a
          participant in the SIGECo Pension Plan on
          June 30, 2000, who performs one Hour of Service
          as a Member after June 30, 2000 and who has not
          already begun receiving benefits under this Plan
          shall be credited, as of the first day he is
          credited with an Hour of Service as a Member and
          as an Active Employee after June 30, 2000 with an
          initial Cash Balance Account balance equal to the
          Actuarial Equivalent of his accrued benefit under
          the SIGECo Pension Plan (as determined in
          accordance with the provisions of the SIGECo
          Pension Plan in effect on June 30, 2000 and based
          on the Applicable Interest Rate and Applicable
          Mortality Table in effect for the year of the
          conversion); provided, however, that, except as
          provided in Section 4.13, no initial Cash Balance
          Account balance shall be established for any
          Transitional SIGECo Member.

In addition to the initial Cash Balance Account balance,
additional credits shall be made to certain Members in accordance
with Section 4.13.

    Each Participant's Cash Balance Account shall further be
credited with interest, using the Credited Interest Rate, on each
calendar day beginning on the later of January 1, 1999 or the
date on which the Member becomes a Member under Article III and
continuing through that Member's Annuity Starting Date.  Interest
credited to a Member's Cash Balance Account during a Plan Year
shall be calculated based on the balance of that Participant's
Cash Balance Account as of the last day of the immediately
preceding Plan Year.

    With respect to any Participant whose benefit is not paid in
a single lump sum and whose Annuity Starting Date is before his
Normal Retirement Date, interest shall be credited to his Cash
Balance Account from his Annuity Starting Date through his
projected Normal Retirement Date at a rate equal to the Credited
Interest Rate at his Annuity Starting Date.  The Cash Balance
Benefit shall then be converted to a single life annuity using
the Applicable Interest Rate and the Applicable Mortality Table
(as defined in Section 2.03).

    Section 4.05.  Protection of Accrued Benefits.
Notwithstanding anything in this Plan to the contrary, the
pension benefit payable under this Plan to any Member, former
Member or terminated Member who, as of December 31, 1998, had not
yet begun to receive benefits under this Plan shall not be less
than the benefit accrued by that Member, former Member or
terminated Member as of December 31, 1998.

    Section 4.06.  Late Retirement Benefit.  A Member may, in
accordance with the ADEA, remain in the employ of the Controlled
Group Entities after his Normal Retirement Date, in which event
no Monthly Retirement Income shall be paid until the Member's
Late Retirement Date except to the extent required under Section
5.05; provided, however, that such deferral of his Monthly
Retirement Income shall be permitted only so long as he completes
at least forty (40) Hours of Service per month and only after
written notice has been given to him by personal delivery or
certified mail, and such deferral of his Monthly Retirement
Income shall comply with all requirements then imposed pursuant
to Section 2530.203-3 of the Department of Labor Regulations
(Chapter 29 of the Code of Federal Regulations) which are
incorporated herein by reference.  At the Member's Late
Retirement Date he shall thereupon be entitled to receive a
Monthly Retirement Income (other than the Cash Balance Benefit)
which shall be an amount computed under Section 4.03, based upon
his Credited Service and his Average Monthly Earnings up to his
Late Retirement Date.  The Cash Balance Benefit of a Member who
retires on his Late Retirement Date and who receives credit for
at least one (1) Hour of Service after December 31, 1998 shall be
the Actuarial Equivalent of the Member's Cash Balance Account as
of the Member's Annuity Starting Date.

    Section 4.07.  Early Retirement Benefit.  Upon written
application submitted to the Plan Administrator, a Member whose
Attained Age is at least fifty (50) and who has been credited
with at least ten (10) Years of Service may retire as of an Early
Retirement Date; provided, however, that if the Member's date of
participation in the Indiana Gas Plan was before January 1, 1976
he may retire as of the first (1st) calendar day of any month on
or following his fiftieth (50th) birthday regardless of his Years
of Service if he had at least five (5) years of participation in
the Indiana Gas Plan.  Commencing at his Early Retirement Date,
any such Member shall be entitled to a Monthly Retirement Income
equal to the portion of his Accrued Benefit (other than the Cash
Balance Benefit) as of his Early Retirement Date but reduced in
accordance with the following table to account for the
commencement of his benefit payments prior to reaching Attained
Age sixty-three (63):

            Age at Which                Percentage of
     Benefit Payments Commence     Accrued Benefit Payable

            62                             94%

            56                             54%
            55                             47%
            54                             40%
            53                             33%
            52                             26%
            51                             19%
            50                             12%

    Straight line interpolation shall be used to determine
benefits at fractional ages.

    With respect to a Cash Balance Benefit calculated under
Section 4.04, a Member who has attained his Early Retirement Date
shall be entitled either to:

     (a)  A deferred pension commencing at his Normal Retirement
          Date equal to the Actuarial Equivalent of his Cash
          Balance Account as of his Annuity Starting Date, or

     (b)  A pension commencing as of the first day of any month
          coincident with or next following his Early Retirement
          Date based on the Actuarial Equivalent of his Cash
          Balance Benefit as of his Annuity Starting Date.

    A Member who terminates his employment with the Controlled
Group Entities for any reason other than Total and Permanent
Disability after meeting the requirements of this Section 4.07
and before reaching his Normal Retirement Date shall be
considered to have retired under this Section 4.07 for the
purposes of Section 5.02.

    A Member whose benefits are determined under Section 4.14
shall be reduced by three-twelfths (3/12ths) of one percent (1%)
for each month benefit commencement precedes age sixty-two (62).
In addition, a Member who was a participant in the Dayton Pension
Plan (as such term is defined in Section 4.14) on July 31, 2000
and whose employment is terminated before January 1, 2001 shall
be entitled to an additional one hundred and eighty-seven dollars
and fifty cent ($187.50) benefit for the period beginning on his
Annuity Starting Date and ending with the month during which he
attains age sixty-five (65); provided, however, that if a married
Member dies while employed or after meeting the requirements for
early or normal retirement under the Dayton Pension Plan, his
surviving spouse shall be entitled to this $187.50 benefit
beginning with the month immediately following his death and
ending in the month that the spouse reaches age sixty-five (65)
or, if earlier, dies; provided, further, that this benefit shall
not be payable if the Member terminates employment before meeting
the requirements for early retirement under the Dayton Pension
Plan or if the Member's benefits are not determined in accordance
with Section 4.14.

    Section 4.08.  Disability Retirement Benefit.

     (a)  Grandfathered Members.  When a Member who is a
          Transitional IEI Member with at least sixty (60) Points
          at December 31, 1998 and who has been credited with at
          least ten (10) Years of Service is determined by the
          Plan Administrator to be Totally and Permanently
          Disabled, the Plan Administrator shall certify such
          fact in writing to the Trustee and that Disabled Member
          shall be entitled to receive Disability Payments for
          the non-Cash Balance Benefit as hereinafter provided.

          (i)    Payment of a Disabled Member's benefits
                 hereunder shall be deferred until his Normal
                 Retirement Date; provided, however, that he
                 remains Totally and Permanently Disabled, in
                 which case such period of deferral shall be
                 included in both his Years of Service and his
                 Credited Service for purposes of calculating his
                 benefits hereunder, and his Average Monthly
                 Earnings at his Normal Retirement Date shall be
                 his Average Monthly Earnings as of the date he
                 became Totally and Permanently Disabled.

          (ii)   While a Member is temporarily disabled (as
                 determined by the Plan Administrator), he shall
                 earn Years of Service and Credited Service as
                 provided in subsection (a) above; provided,
                 however, that during the period of his temporary
                 disability Monthly Earnings shall be determined
                 in accordance with the second (2nd) paragraph of
                 Section 2.12.

          (iii)  A Disabled Member may elect to have his
                 Disability Payments begin prior to his Normal
                 Retirement Date at any time after reaching
                 Attained Age fifty (50) by filing a written
                 application with the Plan Administrator.

     Commencing on the first (1st) calendar day of the month
     coincidental with or immediately following the date the
     written application is filed with the Plan Administrator,
     the Disabled Member shall be entitled to a Disability
     Payment equal to his Accrued Benefit as of the date he
     became Totally and Permanently Disabled taking into account
     his Years of Service and his Credited Service granted under
     subsection (i) or subsection (ii) above but reduced in
     accordance with the following table to account for the
     commencement of his benefit payments before his Normal
     Retirement Date:

                                   Percentage of
                 Age at Benefit    Accrued Benefit
               Commencement Date   Payable

                   65, 64 or 63    100%
                   62               94%
                   61               88%
                   60               82%
                   59               75%
                   58               68%
                   57               61%
                   56               54%
                   55               47%
                   54               40%
                   53               33%
                   52               26%
                   51               19%
                   50               12%

     Straight line interpolation shall be used to
     determine benefits at fractional ages.

    If the Disabled Member recovers (as determined conclusively
    by the Plan Administrator under uniform standards
    consistently applied) prior to his Normal Retirement Date
    and returns to the employ of the Controlled Group Entities
    within a reasonable period of time, he shall be given credit
    for his prior Years of Service and his prior Credited
    Service, including his period of Total and Permanent
    Disability, in accordance with Section 3.02.  If he does not
    return to the employ of a Controlled Group Entity within a
    reasonable period of time, he shall be deemed to have
    terminated his employment with the Controlled Group Entities
    as of the date he became Totally and Permanently Disabled,
    and the benefits, if any, to which he is entitled shall be
    calculated pursuant to Section 5.01 based on his Attained
    Age, his Years of Service and his Credited Service as of the
    date he became Totally and Permanently Disabled (excluding
    any Years of Service for which he would otherwise have been
    given credit under this subsection).

    (b)   Cash Balance Plan Members.  The Cash Balance Account
          of a Member who is determined to be Totally and
          Permanently Disabled and on or after January 1, 1999
          shall continue to be maintained after his disability
          as provided in this subsection.  Such Cash Balance
          Account shall be credited with Pay Credits and
          interest, calculated in accordance with Section 4.04
          and assuming that the disabled Member earned Plan Year
          Compensation during his disability in an amount equal
          to his rate of Monthly Earnings in effect at the date
          immediately preceding his Total and Permanent
          Disability, until the earlier of the disabled Member's
          Normal Retirement Date, actual retirement or recovery
          from disability.  In lieu of further crediting of Pay
          Credits and interest to his Cash Balance Account under
          the preceding sentence, a disabled Member may elect to
          receive the pension benefit described in Section 4.07
          or Section 5.01, whichever is applicable, at any time.

          If a disabled Member begins receiving a pension
          benefit under this Section and later recovers from his
          disability and resumes employment with an Employer
          before attaining Normal Retirement Age, his pension
          benefit payments shall immediately cease, he shall
          have a Cash Balance Account reinstated for his benefit
          and he shall thereafter be eligible to receive Pay
          Credits and interest in accordance with Section 4.04.
          In addition, his reinstated Cash Balance Account shall
          be credited, as of his return to employment with the
          Employers, with an initial balance equal to his Cash
          Balance Account balance at the time he began receiving
          a pension benefit under this Section minus the
          Actuarial Equivalent (determined as of the date he
          began receiving a pension benefit under this Section)
          of those pension benefits paid to him under this
          Section.

    (c)   VEDO Members.  Disability benefits paid to a Member
          who is employed by Vectren Energy Delivery of Ohio,
          Inc. shall be determined in accordance with Section
          4.14 and the Dayton Pension Plan (as such term is
          defined in Section 4.14).

    Section 4.09.  Nonforfeitability.  A Member who reaches
Attained Age sixty-five (65) while still in the employ of a
Controlled Group Entity shall have a fully vested and
nonforfeitable right to receive a Monthly Retirement Income
determined in accordance with Section 4.03 or Section 4.04.  A
Member's Accrued Benefit under this Plan shall be deemed to be
fully vested and nonforfeitable after completion of at least five
(5) Years of Service (or five (5) years of participation in the
Indiana Gas Plan in the case of a Member who was a participant in
the Indiana Gas Plan prior to January 1, 1976).  The Accrued
Benefits of any Employee who was a Member on January 1, 1989
shall also be fully vested and nonforfeitable as of January 1,
1990 regardless of that Employee's age or Years of Service.

          1984 who would otherwise not receive the benefits
          prescribed by the previous Sections of this Article IV

                     after satisfying the eligibility
                     requirements for the payment of benefits
                     under this Plan and thereafter dies before
                     beginning to receive such benefits;

                 then such benefits shall be paid under this
                 Plan in the form of a qualified joint and
                 survivor annuity unless the Member has elected
                 otherwise during the election period.  The
                 election period shall begin at least six (6)
                 months before the Member attains the qualified
                 early retirement age and shall end not before
                 the commencement of his benefit payments.  Any
                 election hereunder shall be in writing and may

          (ii)   Election of early survivor annuity - any Member
                 who is employed by the Controlled Group

                 to elect during the election period to have a
                 survivor annuity payable on his death.  If the
                 Member elects the survivor annuity, payments
                 under such annuity shall not be less than the
                 payments which would have been made to his
                 Spouse under the qualified joint and survivor
                 annuity if the Member had retired on the day
                 before his death.  Any election under this
                 provision shall be in writing and may be
                 changed by the Member at any time.  The
                 election period shall begin on the later of:

                 (A)  the ninetieth (90th) calendar day before
                      the Member attains the qualified early
                      retirement age, or

                 (B)  the date on which his Plan participation
                      begins,

                 and shall end on the date the Member terminates
                 his employment with the Controlled Group
                 Entities.

          (iii)  For purposes of this subsection (d):

                 (A)  Qualified early retirement age is the
                      latest of:

                      (1)  the earliest date under this Plan on
                           which a Member may elect to receive
                           payment of his vested benefits,

                      (2)  the first (1st) calendar day of the
                           one hundred and twentieth (120th)
                           month beginning before the Member
                           reaches the Normal Retirement Date,

                           his participation in this Plan.

                 (B)  Qualified joint and survivor annuity is an
                      annuity for the life of the Member with a
                      survivor annuity for the life of his
                      Spouse as described in Section 4.02.

                      (0.01)) between the date on which the
                      Member's retirement benefits commenced or,
                      if the Member died before the commencement
                      of his retirement benefits, the date on
                      which benefits commenced to his

          a former Member or the Beneficiary of a deceased Member
          is receiving a monthly benefit on January 1, 1999 and
          if the Member's or deceased Member's benefit
          commencement began before January 1, 1999, that Member
          or, if applicable, his Beneficiary shall receive an

          for the period after December 31, 1993 under
          Subsection (b) of Section 4.03, the thirty-five (35)

          (i)    Subject to the conditions set forth in
                 subsection (d) hereof, on the death of a single
                 or married active Member (whether or not vested
                 in accordance with Section 5.1), vested Member
                 or former Member, his Beneficiary, if his
                 Beneficiary has survived him, shall be entitled
                 to receive immediately a monthly benefit equal
                 to the Actuarial Equivalent of one hundred
                 percent (100%) of the Member's Cash Balance
                 Benefit that would have been payable had the
                 Member or former Member begun to receive
                 benefits at Normal Retirement Date, payable as
                 a single life annuity.

          (ii)   The Beneficiary of the benefit described in (i)
                 above may elect to receive the Cash Balance
                 Account balance in lieu of the annuity provided
                 for in (a)(i).  Such election must be made by
                 notification to the Plan Administrator within
                 the ninety (90) day period ending on the date
                 the death benefit is due to commence.  Any
                 election for a lump sum death benefit made
                 under this subsection (ii) may be revoked by a
                 Spouse during the specified election period.
                 Such revocation shall be effected by written
                 notification to the representative designated
                 by the Plan Administrator.  Following such
                 revocation, another waiver under this
                 subsection (ii) may be made at any time during
                 the specified ninety (90) day election period.

          (iii)  Notwithstanding anything contained herein to
                 the contrary, with respect to a Transitional
                 IEI Member who has completed at least sixty
                 (60) Points at December 31, 1998, who dies
                 before his Annuity Starting Date and who is
                 survived by a Spouse, his Surviving Spouse
                 shall be entitled to a death benefit as
                 provided below.  Unless an optional form of
                 benefit is selected within the Election Period
                 pursuant to a Qualified Election, if any vested
                 Member dies on or after the Earliest Retirement
                 Age, but prior to his benefit commencement
                 date, his Surviving Spouse (if any) should
                 receive the benefits that would have been
                 payable if that Member had begun to receive an
                 immediate Qualified Joint and Survivor Annuity
                 on the day before his date of death.  The
                 Surviving Spouse may elect to commence payment
                 under such annuity within a reasonable period
                 after the Member's death; provided, however,
                 that if the benefits commence later than the
                 date on which payments would have been made to
                 the Surviving Spouse under a Qualified Joint
                 and Survivor Annuity, the payment shall be
                 actuarially adjusted consistent with Section
                 2.03 and Section 4.06 to reflect the delayed
                 payment.  Unless an optional form of benefit is
                 selected within the Election Period pursuant to
                 a Qualified Election, if any vested Member dies
                 before the Earliest Retirement Age and before
                 his benefit commencement date, his Surviving
                 Spouse (if any) shall receive the benefit that
                 would have been payable if that Member had
                 terminated his employment with the Controlled
                 Group Entities on his date of death, survived
                 to the Earliest Retirement Age, retired with an
                 immediate Qualified Joint and Survivor Annuity
                 at the Earliest Retirement Age, and then died
                 on the day after the Earliest Retirement Age;
                 provided, however, that in the case of a vested
                 terminated Member, his benefit shall be
                 computed based on his Years of Service as of
                 the date at which his employment with the
                 Controlled Group Entities was actually
                 terminated.  A Surviving Spouse shall begin to
                 receive payments at the Earliest Retirement Age
                 unless that Surviving Spouse elects a later
                 payment commencement date; provided, however,
                 that if a later payment date is elected by the
                 Surviving Spouse, the payments shall be
                 actuarially adjusted consistent with Section
                 2.03 and Section 4.06 to reflect the later
                 payment date.  The death benefit described
                 under this subsection (iii) shall only apply to
                 the Transitional IEI Member's Accrued Benefit
                 as determined under the formula in effect on
                 December 31, 1998, and any death benefit
                 payable to that Member's Spouse or other
                 Beneficiary with respect to his Cash Balance
                 Benefit shall be determined under the other
                 provisions set forth in this Section.

     (b)  Election to Defer.  A Member's or former Member's
          surviving Spouse shall have the right to elect to
          defer payment of the death benefit until the date the
          Member would have reached his Normal Retirement Age,
          had he lived.  A non-Spouse Beneficiary shall receive
          his or her benefit in the form of a single lump sum
          and not have the right to defer commencment of the
          benefit

     (c)  Information to Members.  The Plan Administrator shall
          provide a Member or former Member with information
          with respect to the pre-Annuity Starting Date death
          benefit which information shall be provided in a
          manner similar to the information with respect to the
          qualified joint and survivor annuity and in a manner
          which will reasonably assure that it will be received:
          (i) as soon as feasible after a Member becomes a
          Member hereunder; and (ii) also within the one-year
          period prior to the first day of the Plan Year in
          which the Member or former Member attains age 32 and
          ending with the close of the Plan Year preceding the
          Plan Year in which the Member or former Member attains
          age 35.  In the case of a terminated Member who is
          separated from service prior to the election period
          noted above, the Plan Administrator shall provide a
          terminated Member with the information within a one-
          year period following separation from service with
          respect to benefits accrued prior to separation from
          service.  In the case of a Member who commences
          participation after age 32, the information shall be
          provided to the Member as soon as feasible after he
          became a Member, but no later than the end of the one-
          year period after he becomes a Member.

     (d)  Election to Waive Pre-Annuity Starting Date Spouse's
          Death Benefit-General Rules.  A Member or former
          Member who is married may waive the qualified pre-
          Annuity Starting Date death benefit for his Spouse and
          may designate an alternate Beneficiary to receive such
          benefits by designating an alternate Beneficiary, but
          only in accordance with the rules described below.

          The election period to waive the pre-Annuity Starting
          Date Spouse's death benefit shall be the period which
          begins on the first day of the Plan Year in which the
          Member attains age 35 and ends on the earlier of the
          date of the Member's or former Member's death or the
          Annuity Starting Date.  In the case of a Member or
          former Member, the applicable election period with
          respect to benefits accrued before the date of such
          separation from service shall not begin later than
          such date.

          Notwithstanding the foregoing, the election period to
          waive the pre-Annuity Starting Date Spouse's death
          benefit shall not begin earlier than the date on which
          the Member or former Member is first married.

          Any election to waive the pre-Annuity Starting Date
          Spouse's death benefit shall not take effect unless
          the Spouse of the Member or former Member consents
          irrevocably in writing to such election and the
          Spouse's consent acknowledges the effect of such
          election, including the designation of a specific
          Beneficiary, and the Spouse's consent is witnessed by
          a Notary Public or authorized Plan representative.
          Any consent necessary under this provision will be
          valid only with respect to the Spouse who signs the
          consent, or in the event of a deemed qualified
          election the designated Beneficiary, and must be
          limited to a specific alternate Beneficiary.  Any new
          waiver or change of Beneficiary will require a new
          spousal consent.  The requirements of this paragraph
          may be waived if it is established to the satisfaction
          of the representative designated by the Plan
          Administrator that the consent may not be obtained
          because there is no Spouse or because the Spouse
          cannot be located or because of such other
          circumstances as may be prescribed by regulation, in
          which case a waiver will be deemed a qualified
          election.

          Any election to waive the pre-Annuity Starting Date
          Spouse's death benefit made under this Section may be
          revoked by the Member or former Member during the
          specified election period.  Such revocation shall be
          effected by written notification to the representative
          designated by the Plan Administrator.  Following such
          revocation, another waiver under this Section may be
          made at any time during the specified election period.
          A revocation of a prior waiver may be made at any time
          by a Member or former Member without the consent of
          the Spouse before the Annuity Starting Date.  Any
          actual or constructive election under this paragraph
          having the effect of providing a Spouse's benefit
          automatically shall be revoked if the electing Member
          or former Member ceases to have a Spouse during the
          election period, except to the extent required under a
          qualified domestic relations order.  However, if the
          electing person subsequently remarries, the election
          automatically will be reinstated at that time but will
          be treated as a new election.

    Section 5.03.  Post Retirement Death Benefits.  When a
Retired or Disabled Member who is receiving benefit payments
hereunder dies, his Beneficiary shall be entitled to any benefits
due under the basic or elected optional form of payment of his
Monthly Retirement Income.

    Section 5.04.  Small Benefits.  Notwithstanding any other
provisions of this Plan and effective on and after January 1,
1990, if the Actuarial Value of a terminated or retiring Member's
vested Accrued Benefit, including his Cash Balance Benefit or, if
applicable, the Death Benefits payable to a Surviving Spouse
under Section 5.02 as calculated on or after termination or
retirement and on or before the Annuity Starting Date, when
aggregated with any earlier distribution, is greater than five
thousand dollars ($5,000) but not greater than ten thousand
dollars ($10,000), that Member or, if applicable, his Surviving
Spouse shall be permitted to elect that the Actuarial Value of
the benefits be paid in a single lump sum payment no later than
the last calendar day of the Plan Year following the Plan Year in
which that Member's employment termination date occurred;
provided, however, that if the Actuarial Value of a terminated or
retiring Member's vested Accrued Benefit, Cash Balance Benefit
or, if applicable, the Death Benefits payable to a Surviving
Spouse under Section 5.02 as calculated on or after termination
or retirement and on or before the Annuity Starting Date is and
has at no earlier time after the Member is first entitled to
begin to reserve benefits under this Plan not greater than five
thousand dollars ($5,000) and has not at any time exceeded such
amount, the Actuarial Value of the benefits shall automatically
be paid in a single lump sum payment no later than the last
calendar day of the Plan Year following the Plan Year in which
that Member's employment termination date occurred.  The election
of the Member and the witnessed consent of the Member's Spouse
shall be obtained in writing within the ninety (90) calendar day
period ending on the Annuity Starting Date after receiving
notification which satisfies the requirements under Section
417(a)(3) of the Code. For purposes of this Section 5.04, if the
present value of a Member's vested Accrued Benefit and vested
Cash Balance Benefit is zero (0), that Member shall be deemed to
have received a distribution of his vested Accrued Benefit and
Cash Balance Benefit.  No voluntary or involuntary cashout,
regardless of the dollar amount, shall be permitted under this
Section 5.04 after a Member's Annuity Starting Date.

    Section 5.05.  Commencement of Benefits.  Unless a Member
otherwise elects an earlier or later payment commencement date as
herein provided, the payment of his benefits shall commence not
later than sixty (60) calendar days after the last calendar day
of the Plan Year in which occurs the latest of:

     (a)  that Member's reaching Attained Age sixty-five (65),

     (b)  the tenth (10th) anniversary of that Member's
          Participation Date, or

     (c)  that Member's termination of employment with the
          Controlled Group Entities;

provided, however, that except as otherwise permitted under
Section 5.04 or provided in Section 5.10, the payment of benefits
to a Member shall commence on or before April 1 of the calendar
year following that Member's taxable year in which the Member
reaches age seventy and one-half (70 1/2) or, if the Member has
not reached age seventy and one-half (70 1/2) before January 1,
1999 and is not a five percent (5%) owner of an Employer (within
the meaning of Section 416 of the Code) but only if later, the
April 1 of the calendar year immediately following the Member's
taxable year in which that Member's employment with the
Controlled Group Entities is terminated; provided, further, that
to the extent benefits commence after the April 1 following the
Member's taxable year that he reaches age seventy and one-half
(70 1/2), the benefits shall be increased actuarially, as
determined in accordance with Section 2.03 and applicable
Treasury regulations, to take into account the period after the
April 1 following the Member's taxable year that he reaches age
seventy and one-half (70 1/2) during which benefits are not paid.

    Section 5.06.  Cessation of Benefit Payments to Reemployed
Members.  Notwithstanding any other provisions of this Plan, if
any retired or terminated Member shall be reemployed by a
Controlled Group Entity on a regular full-time basis after his
retirement or termination date and shall complete at least eighty
(80) Hours of Service per month, he shall be treated the same as
a Member continuing in the employ of the Controlled Group
Entities and that portion of his Monthly Retirement Income under
Article IV or under Article V which is attributable to
contributions made on his behalf by the Employers shall, to the
extent already in pay status, be suspended for such period as is
permitted under Section 5.05 and as he shall remain employed by
the Controlled Group Entities on a regular full-time basis and
complete at least eighty (80) Hours of Service per month.
Suspension of benefit payments to any such reemployed Member
shall be made only after written notice has been given to him by
personal delivery or certified mail, and such benefit suspensions
shall comply with all requirements then imposed pursuant to
Section 2530.203-3 of the Department of Labor Regulations
(Chapter 29 of the Code of Federal Regulations) which are
incorporated herein by reference.

    Except as otherwise expressly provided herein and for the Non-
Cash Balance Benefit portion of the Plan, the Years of Service of
such a reemployed Member shall include the period of his
employment by the Controlled Group Entities without a Break in
Service prior to his initial retirement or termination date and,
except as otherwise provided herein, the period of his employment
by the Controlled Group Entities without a Break in Service
subsequent to his reemployment, but except as otherwise expressly
required herein such a reemployed Member's Years of Service shall
not include any service during the period commencing with his
initial retirement or termination date and ending on the calendar
day immediately preceding the date he resumed employment with an
Employer.

    The initial balance of his Cash Balance Account upon his
reemployment shall equal his undistributed Cash Balance Account
(as adjusted to reflect additional interest credits under
Section 4.04) attributable to his prior period of participation
in this Plan; provided, however, that if the Member's benefit is
being paid in a form of an annuity and payments are suspended
under this Section 5.06, the annuity benefit shall first be
converted to a life annuity under Section 2.03, if not already in
the form of a life annuity, and shall then be converted from a
single life annuity to an Acturial Equivalent lump sum.  The
Monthly Retirement Income otherwise payable under this Plan to
that Member after his period of reemployment on a regular full-
time basis by the Employers ends (whose benefit is not converted
into a Cash Balance Account) shall also be reduced by the
Actuarial Equivalent of the Monthly Retirement Income payments,
if any, which he previously received from this Plan to the extent
and in the manner permitted under the aforesaid regulations.

    Section 5.07.  Benefit Decreases Not Permitted.
Notwithstanding any other provisions of this Plan, the benefits
payable hereunder with respect to any Member shall not be
decreased by reason of any increase in the benefit levels or wage
base under Title II of the Federal Social Security Act or under
the Railroad Retirement Act of 1937 if the increase takes place
after the later of:

     (a)  September 2, 1974, or

     (b)  the earlier of the date payment of any benefits under
          this Plan to that Member, his Spouse or other
          Beneficiary commences or the date upon which the
          employment by the Controlled Group Entities of a Member
          who has a nonforfeitable right to benefits under this
          Plan terminates.

    Section 5.08.  Data.  Members, former or retired Members and
the Spouse or other Beneficiary of any deceased Member shall
furnish to the Plan Administrator or Trustee such documents,
evidence or information as the Plan Administrator or Trustee may
consider necessary or desirable for the purpose of administering
this Plan or to protect the Plan Administrator or Trustee; and it
shall be a condition of this Plan that each such person shall
furnish such information promptly and sign such documents as the
Plan Administrator or Trustee may require before any benefits
become payable under this Plan. Failure to furnish such
information or to sign such documents shall not result in any
forfeiture but shall be deemed to be a voluntary election to
postpone payments hereunder.  No interest shall be paid on
benefits as to which the time of commencing payment has been
postponed as herein provided.

    Section 5.09.  No Duplication of Benefits.  Except as
provided in Section 2.64 and Section 3.02 of this Plan and
notwithstanding any other provisions of this Plan, a Member shall
not be entitled to any benefits hereunder with respect to any
period of service with the Employers during which he is accruing
benefits under, or is a participant in, any other tax qualified
defined benefit pension plan towards which the Employers make
contributions on his behalf; nor shall he be entitled to any
benefits if, upon his retirement, he qualifies for any other
benefits under a tax qualified defined benefit pension plan
(other than benefits under the Federal Social Security Act) in
whole or in part financed by the Employers; nor shall the
benefits payable hereunder to any reemployed Employee exceed the
benefits he would otherwise have received had his employment by
the Employers been continuous.  It is the intent of the Employers
that no Member shall receive greater benefits under this Plan by
virtue of the termination of an employment with the Employers and
his subsequent reemployment by an Employer or by virtue of the
termination of his status as an eligible Employee and his
subsequent resumption of eligible Employee status than those
benefits to which he would have been entitled under this Plan
assuming there had been no interruption in his employment by the
Employers or in his status as an eligible Employee.  This Plan
shall be construed and interpreted in accordance with the above
restrictions and in such manner as to prevent any duplication of
benefits based on the same periods of employment by the
Employers.

    Section 5.10.  Direct Transfers. This Section applies to
distributions made on or after January 1, 1993.  Notwithstanding
any provision of the plan to the contrary that would otherwise
limit a distributee's election under this Section, a distributee
may elect, at the time and in the manner prescribed by the Plan
Administrator, to have any portion of an eligible rollover
distribution paid directly to an eligible retirement plan
specified by the distributee in a direct rollover.  For purposes
of this Section, the following terms shall have the meanings set
forth below:

     (a)  Eligible rollover distribution:  An eligible
          rollover distribution is any distribution of all or
          any portion of the balance to the credit of the
          distributee, except that an eligible rollover
          distribution does not include:  (1) any distribution
          that is one of a series of substantially equal
          periodic payments (not less frequently than
          annually) made for the life (or life expectancy) of
          the distributee or the joint lives (or joint life
          expectancies) of the distributee and the
          distributee's designated Beneficiary, or for a
          specified period of ten (10) years or more; (2) any
          distribution to the extent such distribution is
          required under Section 401(a)(9) of the Code; and
          (3) the portion of any distribution that is not
          includible in gross income.

     (b)  Eligible retirement plan:  An eligible retirement
          plan is an individual retirement account described
          in section 408(a) of the Code, an individual
          retirement annuity described in section 408(b) of
          the Code, an annuity plan described in Section
          403(a) of the Code, or a qualified trust described
          in Section 401(a) of the Code, that accepts the
          distributee's eligible rollover distribution.
          However, in the case of an eligible rollover
          distribution to the surviving spouse, an eligible
          retirement plan is an individual retirement account
          or individual retirement annuity.

     (c)  Distributee:  A distributee includes an Employee or
          former Employee.  In addition, the Employee's or
          former Employee's surviving spouse and the
          Employee's or former Employee's spouse or former
          spouse who is an alternate payee under a qualified
          domestic relations order, as defined in section
          414(p) of the Code, are distributees with regard to
          the interest of the spouse or former spouse.

     (d)  Direct rollover:  A direct rollover is a payment by
          the plan to the eligible retirement plan specified
          by the distributee.

    Section 5.11.  Eligibility for Special Retirement Benefit.  A
Member:

     (a)  who on the effective date of the Vectren Merger was an
          Employee;

     (b)  who:

          (i)  is not offered employment with an Employer on and
               after the Vectren Merger;

          or

          (ii) is offered employment with the Employers but does
               not accept the offer because:

               (A)  the employment requires relocation to
                    Evansville, Indiana, or

               (B)  the position has a base salary which is less
                    than 90% of the base salary of the Member's
                    current position or results in a demotion
                    (as determined by the Plan Administrator in
                    its sole and complete discretion);

     (c)  who continues employment with the Employers after the
          Vectren Merger until the Vectren Release Date (as such
          term is defined below);

     (d)  who is not an officer of the Company or of a wholly
          owned, direct or indirect, subsidiary of the Company
          and who does not have in effect an employment agreement
          with the Company or a Company subsidiary,

     (e)  who was a Member on the date on which his employment
          with the Employers is terminated, and

     (f)  who, to the extent required by the Company, executes a
          release on the form provided by the Company

shall be entitled to the benefits described in Section 5.12.

    For purposes of this Article, the term "Vectren Release Date"
shall mean for each Member the date after the Vectren Merger
established by the Company for the Member through which the
Member must remain employed to be eligible for the special
benefits described in Section 5.12 or such other date consented
to by the Senior Vice President, Human Resources and
Administration of the Company.  A Member whose employment is
terminated for reasons other than the reasons set forth above in
this Section shall not be eligible for the benefits described in
Section 5.12.  Notwithstanding anything contained herein to the
contrary, the Company may restrict the eligibility, in whole or
in part, to any Member who is a highly compensated participant
(as such term is defined in Section 414(q) of the Code) to the
extent necessary for the Plan to meet the requirements of Section
401(a)(4) of the Code.

    Section 5.12.  Amount of Special Retirement Benefit.  In
addition to the Member's benefits payable under other Sections of
this Plan a Member eligible under Section 5.11 shall be entitled
to a special benefit ("Special Benefit") determined in the
following manner.  The Special Benefit, expressed as a single
lump sum, shall be equal to the product of:

     (a)  102.35% and

     (b)  the product of:

          (i)  the Member's rate of base salary, expressed as a
               weekly amount, in effect immediately prior to the
               Member's termination of employment with the
               Employers, and

          (ii) a number equal to the sum of:

               (A)   the number of Member's Years of Service,
                     rounding up any fractional Year of Service
                     to the nearest whole number, and

               (B)   the number determined by dividing the
                     Member's base salary, expressed as an
                     annual amount, in effect immediately prior
                     to the Member's termination of employment
                     with the Employers, by $5,000 and rounding
                     up to the nearest whole number;

               provided, however, that the number under this
               subsection (ii) shall under no circumstances be
               less than four (4) nor more than twenty-six (26).

The Special Benefit shall be fully vested and nonforfeitable
regardless of the Member's Years of Service.  Payment of the
Special Benefit shall be effected in accordance with the
following rules:

     (1)  If the sum of the Actuarial Value of the Member's
          Accrued Benefit payable under this Plan and the Special
          Benefit is equal to or less than $5,000, the Special
          Benefit shall be paid in a single lump sum as soon as
          practicable after the Member's termination of
          employment.

     (2)  If the sum of the Actuarial Value of the Member's
          Accrued Benefit payable under this Plan and the Special
          Benefit is greater than $5,000 and unless (pursuant to
          a Qualified Election) the Member elects to receive the
          Special Benefit in a single lump sum payable as soon as
          practicable after the Member's termination of
          employment, the Special Benefit shall be converted in
          the manner set forth below to provide additional
          monthly retirement income in the form of a Qualified
          Joint and Survivor Annuity.  The conversion of the
          Special Benefit to a Qualified Joint and Survivor
          Annuity shall be effected by applying the Applicable
          Interest Rate and the applicable mortality table
          described in the last paragraph of Section 2.03.

     (3)  With respect to any Member whose Special Benefit is not
          paid in an immediate lump sum, the Member may elect for
          the monthly benefit to commence immediately or, at the
          option of the Member (but only if later), to commence
          as of the Member's Normal Retirement Date.  If the
          Member's Annuity Starting Date is before the Member's
          Normal Retirement Date, the amount of monthly benefit
          payable shall be the Actuarial Equivalent to the amount
          which would have been payable at his Normal Retirement
          Date.

     (4)  Notwithstanding anything contained herein to the
          contrary, commencement of the Special Benefit may be
          delayed until as soon as practicable after the release
          described in Section 5.11(e) becomes irrevocable.






                           ARTICLE VI

                         ADMINISTRATION


    Section 6.01.  Administration and Claims Appeal.  The Plan
Administrator shall rely on the records of the Employers, as
certified to it, with respect to any and all factual matters
dealing with the employment of an Employee or Member.  In case of
any factual dispute hereunder, the Plan Administrator shall
resolve such dispute, giving due weight to all evidence available
to it.  The Plan Administrator shall interpret this Plan and
shall determine all questions arising in the administration,
interpretation and application of this Plan.  All such
determinations shall be final, conclusive and binding except to
the extent that they are appealed under the following claims
procedure which shall be administered in accordance with Section
503 of the Act.  If the written claim of any person to all or any
part of any payment or benefit under this Plan shall be denied,
the Plan Administrator shall provide to the claimant, within
ninety (90) calendar days after receipt of such written claim, a
written notice setting forth, in a manner calculated to be
understood by the claimant:

     (a)  the specific reason or reasons for the denial,

     (b)  specific references to the pertinent Plan provisions on
          which the denial is based,

     (c)  a description of any additional material or information
          necessary for the claimant to perfect the claim and an
          explanation as to why such material or information is
          necessary, and

     (d)  an explanation of this Plan's claim review procedure.

    Within sixty (60) calendar days after receipt of the above
material, the claimant shall have a reasonable opportunity to
request in writing a full and fair review of the claim denial by
the Plan Administrator.  The claimant or his duly authorized
representative may, but only within the sixty (60) calendar day
period:

     (e)  request a review upon written notice to the Plan
          Administrator,

     (f)  review pertinent documents, and

     (g)  submit issues and comments in writing

    A decision on review by the Plan Administrator shall be made
not later than sixty (60) calendar days after receipt of a
written request for review, unless special circumstances require
an extension of time for processing, in which event a decision on
review shall be rendered as soon as possible but in no event
later than one hundred and twenty (120) calendar days after
receipt of such written request.  The Plan Administrator's
decision on review shall be written and shall include specific
reasons for the decision, written in a manner calculated to be
understood by the claimant, with specific references to the
pertinent Plan provisions on which the decision on review is
based.

    Section 6.02.  Trustee Direction.  The Secretary of the Plan
Administrator shall direct the Trustee in writing to make
payments from the Trust Fund to Members who qualify for such
payments hereunder, as certified to it by the Actuary.  Such
written order to the Trustee shall specify the name of the
Member, his address, his Social Security number and the amount
and frequency of such payments.

    Section 6.03.  Nondiscriminatory Actions.  The Plan
Administrator shall not take action or direct the Trustee to take
any action with respect to any of the benefits provided hereunder
or otherwise in pursuance of the powers conferred herein upon the
Plan Administrator which would be discriminatory in favor of
Members or Employees who are officers, shareholders or highly-
compensated employees or which would result in benefiting one (l)
Member or group of Members at the expense of another or in the
application of different rules to substantially similar sets of
facts.

    Section 6.04.  Fiduciary Responsibilities.  The powers of the
Plan Administrator shall be specifically subject to the
allocation of fiduciary responsibilities contained in Article
VIII.

    Section 6.05.  Agents.  The Plan Administrator may employ
such counsel (who may, but need not, be counsel to an Employer or
to the Trustee), accountants and other agents as it shall deem
advisable.  The Employers shall pay, or cause to be paid from the
Trust Fund to the fullest extent then permitted under the Act and
under the Code, the reasonable compensation of such counsel,
accountants and other agents and any other reasonable expenses
incurred by the Plan Administrator in the administration of this
Plan and the Trust Fund.





ARTICLE VII
                            FINANCING


    Section 7.01.  Intent to Contribute.  It is the intention of
the Employers on a pro rata basis, but they do not guarantee to
do so, to deposit with the Trustee from time to time the funds
actuarially necessary to provide the benefits under this Plan, in
a manner consistent with the funding standards mandated by the
Act and by the Code.

    Section 7.02.  Expenses.  To the extent permitted under the
Act and under the Code, all reasonable expenses of administering
this Plan and the Trust Fund shall be paid from the Trust Fund;
provided, however, that notwithstanding the above, the Company
may, but is not required to, elect to have such expenses paid
directly by the Employers.

    Section 7.03.  Funding Standard Account.  A funding standard
account shall be established and maintained, so that it may be
determined whether or not the Employers have complied with
minimum funding standards under the Act and under the Code.






                          ARTICLE VIII

                   THE TRUST FUND AND TRUSTEE


    Section 8.01.  Exclusive Benefit.  Simultaneously with the
execution and delivery of this Plan and the Trust Agreement and
subject to any regulatory waiting periods, the Company directed
the funding agents of the Indiana Gas Plan and of the Central
Plan to transfer the assets attributable thereto to the Trustee.
Such funds and such other funds or securities that shall be
deposited with the Trustee under the terms hereof, and any
increment thereto and income therefrom, shall constitute the
Trust Fund established hereunder and shall be held by the Trustee
in trust in a manner consistent with the objectives of this Plan
and requirements imposed under the Code and under the Act for the
exclusive benefit of Members, Retired Members and Disabled
Members or their Beneficiaries or Spouses.  The Trustee shall
hold and dispose of the pension fund in trust for the sole and
exclusive benefit of the Participants, their spouses or other
Beneficiaries (or estates) upon and subject to the provisions of
this Plan and to the provisions of the Trust Agreement.

    Section 8.02.  Trust Fund Purpose.  The Trust Fund is
established and proposed to be continued in order to provide
benefits for Employees who are Members in the event of their
Total and Permanent Disability, Early, Normal, Late or Special
Retirement, other termination of employment, and under certain
conditions, Death Benefits for Spouses of deceased Members, all
in accordance with the terms and provisions of this Plan and
requirements imposed under the Code and under the Act.

    Section 8.03.  Investment Manager.  Notwithstanding anything
to the contrary herein contained and except as otherwise provided
by the Trust Agreement, the Company may appoint an investment
manager or managers to manage all or a portion of the assets of
the Trust fund for which the Trustee is responsible for the
investment thereof; provided, however, that during any period in
which there is in existence an investment committee for the Plan
appointed by the Board of Directors of the Company, the power to
appoint an investment manager or managers shall reside with such
investment committee.  If the Company or, if applicable, the
investment committee appoints an investment manager to manage the
Trust Fund, in whole or in part, and delivers to the Trustee a
copy of the instruments appointing the investment manager and
evidencing the investment manager's acceptance of such
appointment, an acknowledgment by the investment manager that it
is a fiduciary under this Plan and under the Act and a
certificate evidencing the investment manager's current
registration under the Investment Advisers Act of 1940, the
Trustee shall be fully protected in relying upon such instruments
and certificate until otherwise notified in writing by the
Company.

    Section 8.04.  Expenses.  The Employers on a pro rata basis
shall pay, or cause to be paid from the Trust Fund to the fullest
extent then permitted under the Act and under the Code, all
necessary expenses that may arise in connection with the
administration of the Trust Fund.  The Company and the Trustee
shall enter into a separate written agreement as to the amount of
the Trustee's fees.  If such expenses or fees are not paid
directly by the Employers, the Trustee may deduct them from the
earnings or corpus of the Trust Fund to the extent then permitted
under the Act and under the Code.

    Section 8.05.  Investment Committee Directions.
Notwithstanding anything contained in this Article VIII to the
contrary and except as otherwise provided by the Trust Agreement
or by the Act or by the Code, it shall be the duty of the Trustee
to act strictly in accordance with any investment recommendations
or directions of the Investment Committee as to all of the Trust
Fund or a portion thereof.  Except as otherwise provided by the
Act or by the Code, the Trustee shall be under no duty to
question any such recommendation or any such direction of the
Investment Committee or to review any securities or other
property held in the Trust Fund pursuant to such recommendations
or directions.

    Section 8.06.  Establishment of Section 401(h) Account.
Effective on and after January 1, 1995, the Company may elect to
make contributions to a separate account maintained by the
Trustee in accordance with Code Section 401(h) ("401(h) Account).
In such event, the Company shall expressly designate the amount
to be allocated to the 401(h) Account.  The amounts held in the
401(h) Account, if any, shall be applied to provide post
retirement medical benefits to the covered Members and their
spouses and other beneficiaries; provided, however, that only
Members whose retirement benefits hereunder are in pay status
shall be eligible for benefits hereunder; provided, further, that
no amounts shall be applied to provide such benefits to key
employees (as such term is defined under Section 14.02) unless
the amounts are paid from separate sub-accounts of the 401(h)
Account maintained in the name of each such key employee.  The
expenses eligible for reimbursement shall be limited to medical
expenses as defined in Code Section 213(e)(1).  The maximum Plan
Year reimbursement which may be made to a Member and his spouse
and other beneficiaries shall not exceed an amount established by
the Company at the time of the first contribution.  The medical
benefits provided hereunder must be subordinate to the retirement
benefits provided hereunder, and the aggregate Employer
contributions to be allocated to the 401(h) Account may not
exceed twenty-five percent (25%) of the aggregate contributions
made by the Employers to provide retirement benefits for the
period beginning on January 1, 1995.  The amounts contributed to
the 401(h) Account must be reasonable and ascertainable, be
applied only for medical benefits (and not retirement benefits)
and may not be returned to the Employers until after the
satisfaction of all liabilities, and once satisfied, any
remaining funds in the 401(h) Account shall be returned to the
Employers.  If a Member's interest in the 401(h) Account is
forfeited, the forfeiture amount shall reduce the amount required
to be contributed by the Employers under this Section.





                           ARTICLE IX
             RESERVATION OF RIGHTS BY EMPLOYERS AND
                LIMITATIONS ON RIGHTS OF MEMBERS

    Section 9.01.  Plan Voluntary.  Although it is the intention
of the Employers that this Plan shall be continued and
contributions made regularly for each Plan Year, this Plan is
entirely voluntary on the part of the Employers and the
continuance of this Plan and the payments hereunder are not
assumed as a contractual obligation of the Employers.  The
Employers do not guarantee or promise to pay or to cause to be
paid any of the benefits provided by this Plan.

    Section 9.02.  Right to Modify Plan.  Vectren Corporation
specifically reserves the right in accordance with Article X, to
modify, suspend, in whole or in part, at any time or from time to
time and for any period or periods or to discontinue at any time
the contributions specified in Article VII.

    Section 9.03.  Employment Rights Not Affected.  This Plan
shall not be deemed to constitute a contract between the
Employers and any Member or to be a consideration or an
inducement for the employment of any Member or Employee. Nothing
contained in this Plan shall be deemed to give any Member or
Employee the right to be retained in the service of the Employers
or to interfere with the right of the Employers to discharge any
Member or Employee at any time, regardless of the effect which
such discharge shall have upon him as a Member of this Plan.

    Section 9.04.  Payment from Other Plans.  If any Member is or
becomes or upon proper application would become entitled to a
pension or other benefits under any other tax qualified defined
benefit pension plan of which the Employers have borne or of
which Richmond Gas Corporation or Terre Haute Gas Corporation has
borne, or are required to bear, any part of the cost, the Monthly
Retirement Income payable to that Member under the provisions of
this Plan shall be reduced to reflect the Actuarial Value of the
benefits payable under such other  tax qualified defined benefit
pension plan to the extent that credit is granted under both
plans for the same Years of Service; provided, however, that if
any such other qualified defined benefit plan has a similar
offset applicable to benefits accrued under other qualified
defined benefit plans funded by the Employers, by Richmond Gas
Corporation or by Terre Haute Gas Corporation, benefits under
this Plan attributable to the same period of service shall first
be offset under this Plan before the offset described above is
applied for such other plan.  The term "other tax qualified
defined benefit pension plan" shall not include any plan or
program under which benefits are provided wholly or in part by
public funds, State or Federal.

    Section 9.05.  Spendthrift Provision.  None of the benefits
under this Plan shall be subject to the claims of creditors of
Members, Retired Members or Disabled Members or of their Spouses
or other Beneficiaries and such benefits shall not be subject to
attachment, garnishment or any other legal or equitable process.
Neither a Member, a Retired Member, a Disabled Member, a
Beneficiary nor a Spouse may assign, sell, borrow on or otherwise
encumber any of his beneficial interest in the Trust Fund, nor
shall any such benefits be in any manner liable for or subject to
the deeds, contracts, liabilities, engagements or torts of any
Member, Retired Member, Disabled Member, Beneficiary or Spouse.
Notwithstanding anything in this Plan to the contrary, a Member's
Spouse, Surviving Spouse, Beneficiary or any other person
claiming benefits on behalf of a Member shall have absolutely no
rights whatsoever under this Plan prior to the death of that
Member.  It is the intention of the Employers that benefit
payments hereunder shall be made only at the times, in the
amounts and to the payees as specified in this Plan regardless of
any marital dissolution, bankruptcy or other legal proceedings to
which such payees may be a party. The preceding sentences shall
also apply to the creation, assignment or recognition of a right
to any benefit payable with respect to a Member pursuant to a
domestic relations order, unless such order is determined by the
Plan Administrator to be a qualified domestic relations order as
then defined in Section 414(p) of the Code.  A domestic relations
order entered before January 1, 1985 shall be treated as a
qualified domestic relations order only if payment of benefits
pursuant to that order had commenced as of such date.

    Section 9.06.  Intent and Reversions.  It is intended that
this Plan and the Trust Agreement shall continue to be approved
and qualified by the Internal Revenue Service as meeting the
requirements of the Code with respect to employee plans and
trusts:

     (a)  so as to permit the Employers to deduct for federal
          income tax purposes the amount of their contributions
          to the Trust Fund,

     (b)  so that contributions so made and the income of the
          Trust Fund shall not be taxable to Members as income
          until received, and

     (c)  so that the income of the Trust Fund shall be exempt
          from federal income tax.


    If the Commissioner of Internal Revenue or his delegate rules
that a deduction for all or any part of an Employer's
contribution is not allowed, that Employer shall recover, within
one (l) year after the disallowance of such deduction, that
portion or all of its contribution for which no deduction is
allowed.  In addition, if an Employer makes a contribution as the
result of a mistake in fact, that Employer reserves the right to
recover the amount of such contribution, within one (l) year
following the date the contribution was transferred to the
Trustee.






                            ARTICLE X

                           AMENDMENTS

    Subject to such advance written notice as may be required
under the Act or under the Code, the Chief Executive Officer or
the President of the Company reserves the right at any time and
from time to time, without the consent of Members, active or
retired, Spouses, Beneficiaries or any person or persons claiming
through them, to modify or amend, in whole or in part, any or all
of the provisions of this Plan, including specifically the right
to make any such amendments effective retroactively, if
necessary, to bring this Plan into conformity with governmental
regulations under the Act or under the Code which must be
complied with in order to make this Plan eligible for tax
benefits; provided, however, that no such modification or
amendment shall:

     (a)  effect any discrimination among the Members;

     (b)  increase the duties or responsibilities of the
          Trustee without its written consent;

     (c)  cause or permit any part of the Trust Fund to be
          diverted to purposes other than for the sole and
          exclusive benefit of the Members, Retired Members
          or Disabled Members or their Spouses or other
          Beneficiaries or permit or cause any portion of
          the Trust Fund to revert to or to become the
          property of the Employer except to the extent
          otherwise permitted in Section 9.06 or in Section
          11.05 and then permitted by the Act and by the
          Code; or

     (d)  change the vesting schedule in Section 5.01 or in
          Section 14.04 unless each Member who had
          completed three (3) or more Years of Service
          prior to the effective date of such alteration,
          amendment, modification, revocation or
          termination is permitted to elect, within sixty
          (60) calendar days after the latest of the date
          on which the amendment is adopted, the date on
          which the amendment is effective or the date on
          which he is notified in writing by the Plan
          Administrator of his rights under this subsection
          (d), to have his vested interest determined
          without regard to such alteration, amendment,
          modification, revocation or termination;

provided, further, that no such modification or amendment on or
after July 30, 1984 (including a change in the actuarial basis
for determining optional or early retirement benefits) shall be
effective to the extent that it has the effect of decreasing a
Member's Accrued Benefit; provided, further, that the Board of
Directors of the Company must approve any Plan amendment that
results in an increase in benefits and costs to the Company with
a present value (as determined by the Actuary) as of the date of
the amendment in excess of one million dollars ($1,000,000).





                           ARTICLE XI

          PERMANENT OR TEMPORARY DISCONTINUANCE OF PLAN


    Section 11.01.  Termination by Board of Directors.  Subject
to such advance written notice or other requirements as may be
required under the Act or under the Code, any Employer, by action
of its Board of Directors, may suspend contributions to the Trust
Fund for any Plan Year and may terminate this Plan, in whole or
in part, at any time with respect to that Employer's Employees.

    Section 11.02.  Valuation and Apportionment.  If any Employer
terminates this Plan or permanently suspends its contributions to
the Trust Fund or if a termination, in whole or in part, is
deemed to have occurred by operation of law with respect to that
Employer's Employees, the Plan Administrator shall direct the
Trustee to compute the value of the Trust Fund held for the
benefit of affected Members, Retired Members, vested terminated
Members, Disabled Members, Spouses and Beneficiaries otherwise
eligible to receive benefits hereunder. The Plan Administrator,
based upon the certification of the Actuary, shall apportion the
amount so valued to all such affected Members, Retired Members,
vested terminated Members, Disabled Members, and/or their Spouses
or other Beneficiaries in shares as determined in Section 11.03,
but subject to the provisions of Section 11.06.

    Section 11.03.  Allocation of Trust Fund.  The value of that
portion of the Trust Fund remaining after providing for the
reasonable expenses of administration of this Plan and of the
Trust Fund to the fullest extent then permitted under the Act and
under the Code shall be allocated for purposes of paying Monthly
Retirement Income, Disability Payments and Death Benefits in the
order of precedence and in the amounts indicated in Section 4044
of the Act according to the principles set forth therein.

    The allocation of the Trust Fund in accordance with this
Section 11.03 shall be based on the method of payment of Monthly
Retirement Income, Disability Payments or Death Benefits
specified in this Plan.  If the Trust Fund assets on or after the
date of termination are insufficient to fund all benefits within
any class, the benefits of all lower order of precedence shall be
unfunded and the assets shall be allocated among Members of that
class on the basis of their respective actuarial reserves,
subject to the provisions of Section 4044 of the Act.

    Section 11.04.  Outstanding Expenses.  In the event of
failure of an Employer upon termination of this Plan with respect
to its Employees to pay or to reimburse the Trustee or the
Actuary for the then outstanding charges or expenses incurred
hereunder, the Trustee, subject to any limitations then imposed
under the Act and under the Code, is empowered to satisfy such
claims by lien upon the Trust Fund, prior to making any
allocation to affected Members, vested terminated Members,
Retired Members, Disabled Members and their Spouses or other
Beneficiaries under this Plan in accordance with Section 11.02
and Section 11.03.

    Section 11.05.  Distribution.  The application of the Trust
Fund on the foregoing basis shall be calculated by the Actuary
and certified to the Trustee by the Plan Administrator as of the
date on which this Plan was terminated.  Subject to the
restrictions of the Act and of the Code, when the calculations
shall be completed, the interest of each affected Member, vested
terminated Member, Retired Member, Disabled Member, Beneficiary
and Spouse shall continue to be held in the Trust Fund pursuant
to the terms of Section 11.03 shall be liquidated and each of
their interests distributed to them in the form of annuity
contracts; provided, however, that any funds remaining after the
satisfaction of all liabilities to Members, vested terminated
Members, Retired Members, Disabled Members, Beneficiaries and
Spouses under this Plan, if due to erroneous actuarial
computation, shall be returned to the applicable Employers to the
fullest extent then permitted under the Code and under the Act.
The terms of any annuity contract purchased and distributed
pursuant to this Section 11.05 shall comply with the terms of
this Plan and with all requirements imposed by the Act or by the
Code, including but not limited to Spousal consent requirements.
Any such annuity contracts shall be nontransferable.

    Section 11.06.  Temporary Restriction on Benefits.
Notwithstanding any provisions contained herein to the contrary,
the amount of the Trust Fund assets contributed by the Employers
under this Plan which may be used in any Plan Year for the
benefit of any Member, including a vested terminated Member or a
Retired Member, who was among an Employer's twenty-five (25) most
highly-compensated employees for such Plan Year (herein referred
to as a "Highly Compensated Employee") or the Beneficiary of any
such Highly Compensated Employee shall be subject to the
restrictions described below:

     (a)  In the event of Plan termination, the benefit of
          any Highly Compensated Employee shall be limited
          to a benefit that is non-discriminatory under
          Section 401(a)(4) of the Code.

     (b)  The annual payments to a Highly Compensated
          Employee shall be restricted to an amount equal
          to the payments that would be made on behalf of
          such Highly Compensated Employee under a single
          life annuity as the Actuarial Equivalent of the
          sum of such Highly Compensated Employee's Accrued
          Benefit and other benefits payable under the
          Plan; provided, however, that the restrictions in
          the subsection (b) shall not apply if:

          (i)   after payment to such Highly Compensated
                Employee of all benefits (as such term is
                defined below), the value of Plan assets
                equals or exceeds one hundred and ten
                percent (110%) of the value of current
                liabilities (as defined in Section
                412(l)(7) of the Code), or
          (ii)  the value of the benefits (as such term is
                defined below) is less than one percent
                (1%) of the value of current liabilities
                (as defined in Section 412(l)(7) of the
                Code).

For purposes of this Section, the term "benefit" includes loans
in excess of the amount set forth in Section 72(p)(2)(A) of the
Code, any periodic income, any withdrawal values payable to a
living employee and any death benefits not provided for by
insurance on the employee's life.  This Section 11.06 is intended
to meet the requirements of Section 1.401(a)(4)-5 of the Income
Tax Regulations and shall be interpreted consistent with such
Regulations.

    Section 11.07.  Statutory Vesting.  Notwithstanding any other
provisions of this Plan (except the provisions of Section 11.06),
should this Plan terminate or partially terminate, the rights of
all affected past or present Members to benefits accrued to the
date of such termination or partial termination, but only to the
extent then funded, shall be and become fully vested and
nonforfeitable regardless of the affected Members' ages or Years
of Service.  To the extent that such benefits are not funded,
they shall become vested and nonforfeitable in accordance with
Section 4.07, Section 5.01 or, if applicable, Section 14.04.





                           ARTICLE XII

                             ACTUARY


    Section 12.01.  Calculations and Assumptions.  The Actuary
shall make all actuarial calculations and perform all duties
required of him hereunder.  In making an actuarial valuation of
this Plan and of the Trust Fund from time to time, the Actuary
may rely upon the written statement of the Trustee concerning the
assets in the Trust Fund and shall not be required to make any
independent calculations with respect thereto.  The Actuary shall
certify to the Employers in writing the results of the
calculations required of him, and the Employers may rely thereon.
In making all calculations hereunder, the Actuary shall use such
actuarial tables as he deems appropriate but he shall use the
same tables in making all calculations during a specified period.
The Actuary shall employ actuarial assumptions and methods which
are reasonable under applicable laws.  The Actuary may, to the
extent then permitted under the Act and under the Code, from time
to time change the actuarial tables and other assumptions used by
him hereunder.

    Section 12.02.  Valuation.  The Actuary shall perform
periodically an actuarial valuation of this Plan and of the Trust
Fund and shall certify to the Employers in writing the results of
the valuation.  The Actuary in his actuarial valuation shall
apply all gains arising in the operation of this Plan, including
but not necessarily limited to gains resulting from terminations
of employment of Members prior to qualifying for benefits
hereunder, to reduce the contributions of the Employers pursuant
to the funding method and actuarial tables then in use.

    Section 12.03.  Data Reliance.  The Employers shall furnish
the Actuary such information on employees, payrolls and other
related data as the Actuary may require from time to time.  The
Actuary may rely upon any information furnished him by the
Employers or by the Plan Administrator.





                          ARTICLE XIII

                          MISCELLANEOUS


    Section 13.01.  Unstated Rules.  Any rules, regulations or
procedures that may be necessary for the proper administration or
functioning of this Plan that are not covered in this Plan or in
the Trust Agreement shall be promulgated and adopted by the Plan
Administrator.

    Section 13.02.  Headings.  Any headings or subheadings in
this Plan are inserted for convenience of reference only and
shall be ignored in the construction of any provisions hereof.

    Section 13.03.  Construction.  This Plan shall be construed
in accordance with the laws of the State of Indiana, except where
such laws are superseded by the Act.  Any words herein used in
the masculine shall be read and construed in the feminine where
they would so apply.  Words in the singular shall be read and
construed as though used in the plural in all cases where they
would so apply.

    Section 13.04.  Payment to Providers.  In making any
distribution to or for the benefit of any minor or incompetent
Beneficiary, the Plan Administrator, in its sole, absolute and
uncontrolled discretion, may, but need not, order the Trustee to
make such distribution to a legal or natural guardian or other
relative of such minor or court-appointed committee of such
incompetent, or to any adult with whom such minor or incompetent
temporarily or permanently resides, and any such guardian,
committee, relative or other person shall have full authority and
discretion to expend such distribution for the use and benefit of
such minor or incompetent.  The receipt of such guardian,
committee, relative or other person shall, to the extent thereof,
be a complete discharge to the Trustee, without any
responsibility on its part or on the part of the Plan
Administrator to see to the application thereof.

    Section 13.05.  Documents.  An executed copy of this Plan and
the Trust Agreement shall be furnished to the Trustee.  A
conformed copy of this Plan shall be furnished to the Actuary and
to the Plan Administrator.  The Plan Administrator shall, in
accordance with the Act, make available to each Member or, if
deceased, to his Spouse or other Beneficiary for examination by
him, at the principal office of an Employer during regular
business hours, a copy of this Plan and the Trust Agreement and
such of its records or copies thereof as may pertain to any
benefits of that Member under this Plan.

    Section 13.06.  Severability.  If any provisions of this Plan
shall be held illegal or invalid for any reason, such illegality
or invalidity shall not affect the remaining parts of this Plan
and this Plan shall be construed and enforced as if such illegal
and invalid provisions had never been inserted herein.

    Section 13.07.  Named Fiduciaries.  For purposes of Part 4 of
Title I of the Act, the Employers, the Trustee, the Plan
Administrator, the Investment Committee and those parties to whom
any duties are allocated pursuant to Section 8.09, as such
provision may hereafter be amended, shall each be named
fiduciaries.  All actions by named fiduciaries shall be in
accordance with the terms of this Plan and of the Trust Agreement
insofar as such documents are consistent with the provisions of
Title I of the Act and requirements imposed under the Code.  Each
named fiduciary, while discharging its duties under this Plan,
shall act solely in the interest of Members and their Spouses or
other Beneficiaries and for the exclusive purpose of providing
benefits and defraying reasonable administrative expenses.  Each
named fiduciary shall discharge its duties hereunder with the
care, skill, prudence and diligence under circumstances then
prevailing that a prudent man acting in a like capacity and
familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims.  Without
limiting the generality of the above, it is specifically provided
that the appointment and retention of the members of the Plan
Administrator or of any investment manager pursuant to Section
8.09 are duties of the Company or of the Trustee (whichever is
appropriate) for purposes of this Section 13.07.

    Section 13.08.  Allocation of Fiduciary Duties.  The Plan
Administrator shall be responsible for the administration and
management of this Plan except for those duties hereinafter
specifically allocated to the Investment Committee, the Trustee
or to the Actuary.  The Trustee shall have exclusive
responsibility for the management and control of the assets of
this Plan, except to the extent provided by Article XV and
Section 8.16 or to the extent that an investment manager is
appointed pursuant to Section 8.09.  The Actuary shall have the
responsibility for establishing the actuarial assumptions and the
implementation of the actuarial cost method used to determine the
minimum required contributions and the maximum allowable
contributions for this Plan.  The Plan Administrator shall have
exclusive responsibility for all matters specifically delegated
to it by the Employers in this Plan.  Each named fiduciary shall
be responsible only for the specific duties assigned above and
shall not be directly or indirectly responsible for the duties
assigned to another fiduciary.  The Plan Administrator shall be
deemed the Plan administrator for purposes of the Act.

    Section 13.09.  Errors.  A misstatement in the age, sex,
length of Service, date of employment or birth, compensation or
marital status of a Member or any other such matter shall be
corrected when it becomes known that any such misstatement of
fact has occurred.

    Section 13.10.  Merger of Employer.  In the event of a merger
or consolidation of an Employer or the transfer of all or
substantially all of its assets to any other corporation,
partnership or association, provision may be made by such
successor corporation, partnership or association at its sole
election for the continuance of this Plan by such successor
entity.  Such successor shall, upon its election to continue this
Plan, be substituted in place of that Employer by an instrument
duly authorizing such substitution and duly executed by the
Employer and by its successor.  Upon notice of such substitution
accompanied by a certified copy of the resolutions of the Board
of Directors of that Employer and of its successor authorizing
such substitution and delivered to the Trustee, the Trustee and
all Members hereunder shall be authorized to recognize such
successor in the place of that Employer.

    Section 13.11.  Maximum Annual Benefit.  The total annual
benefits (including retirement, disability or severance benefits)
payable during any Plan Year to any Member, his Spouse or other
designated Beneficiary under this Plan or under any other tax
qualified defined benefit plans maintained by the Employers shall
not exceed the limitations contained in Section 415 of the Code.

    Section 13.12.  Defined Contribution Plans.  If any Member is
a participant in any tax qualified defined contribution plan
maintained by the Employers and for Plan Years beginning before
January 1, 2000, the sum of his Defined Benefit Plan Fraction and
of his Defined Contribution Plan Fraction for any Plan Year shall
not exceed one (1).

    Section 13.13.  Adjustments.  If as of any Anniversary Date
corrective adjustments are required pursuant to Section 13.11 or
Section 13.12, the Member's annual benefit shall be reduced by an
amount, determined by the Actuary, adequate to insure compliance
with Section 13.11 and Section 13.12.

    Section 13.14.  Plan Merger.  In the case of any merger or
consolidation with or transfer of assets or liabilities of this
Plan to any other plan, such merger, transfer or consolidation
shall by its terms provide that each Member of this Plan would,
if that plan then terminated, receive a benefit immediately after
the merger, consolidation or transfer which is equal to or
greater than the benefit he would have been entitled to receive
immediately before the merger, consolidation or transfer if this
Plan had then terminated.  A minimum of thirty (30) calendar
days' prior written notice of any such transaction shall be given
to the Internal Revenue Service.

    Section 13.15.  Nondiversion of Plan Assets.  The Employers
shall be entitled to no part of the corpus or income of the Trust
Fund and no part thereof shall be used for or diverted to
purposes other than for the exclusive benefit of the Members and
their Spouses or other Beneficiaries hereunder, except as
otherwise provided in Section 9.06 and in Section 11.05 and then
permitted under the Act and under the Code.

    Section 13.16.  Plan Priority of Excess Benefits.  If the
limits contained in Section 13.11 and in Section 13.12 would be
exceeded in any Plan Year, the benefits accrued under this Plan
and under any other tax qualified defined benefit plans
maintained by the Employers and the Employer contributions to
each type of tax qualified defined contribution plan maintained
by the Employers shall be reduced in the following order of
priority:

     (a)  defined benefit plans,

     (b)  profit sharing plans,

     (c)  money purchase pension plans, and

     (d)  employee stock ownership plans.

    Section 13.17.  Extra-Ordinary Expenses.  To the fullest
extent then permitted under the Code and under the Act, any extra-
ordinary expenses, including but not limited to Trustee's fees
and attorney's fees, incurred by this Plan as the direct result
of a benefit dispute, domestic relations order, bankruptcy or
other legal proceedings involving a Member's Accrued Benefits
under this Plan shall be set off from any benefit payments
otherwise due with respect to that Member in such manner as the
Plan Administrator deems appropriate to protect the interests of
the other Members and their Spouses or other Beneficiaries.  Any
such set off shall be made only with respect to those benefits
which accrue after the adoption of this amendment and restatement
in order to preclude any retroactive effect on a Member's Accrued
Benefits.






                           ARTICLE XIV

                      TEFRA TOP-HEAVY RULES


    Section 14.01.  Application.  The rules set forth in this
Article XIV shall be applicable with respect to any Plan Year
beginning after December 31, 1983 in which this Plan is
determined to be a Top-Heavy Plan.  The provisions of this
Article XIV shall be applied only to the extent necessary to
comply with Section 416 of the Code and in a manner consistent
with all requirements then imposed under Section 416 of the Code.

    Section 14.02.  Determination.  This Plan shall be considered
a Top-Heavy Plan with respect to any Plan Year if as of the last
calendar day of the immediately preceding Plan Year (the
"determination date"):

     (a)  the present value of the accrued benefits (as such
          term is defined in Section 14.03) of key employees
          (as such term is defined below) exceeds sixty
          percent (60%) of the present value of the accrued
          benefits (as such term is defined in Section 14.03)
          of all Employees and former Employees (excluding
          former key employees (as such term is defined
          below)); provided, however, that effective for Plan
          Years beginning after December 31, 1984 the accrued
          benefits (as such term is defined in Section 14.03)
          of any Member who has not completed at least one
          (1) Hour of Service for the Controlled Group
          Entities during a five (5) year period ending on
          the determination date (as such term is defined
          above) shall be disregarded, or

     (b)  this Plan is part of a required aggregation group
          (as such term is defined below) and the required
          aggregation group is top-heavy;

provided, however, that this Plan shall not be considered a Top-
Heavy Plan with respect to any Plan Year in which this Plan is
part of a required or permissive aggregation group (as such terms
are defined below) which is not top-heavy.  For purposes of this
Article XIV, the term "key employee" shall include for any Plan
Year any Employee or former Employee who at any time during that
Plan Year or any of the four (4) immediately preceding Plan Years
is:

     (c)  an officer of a Controlled Group Entity whose
          Section 415 Compensation from the Controlled Group
          Entities is greater than fifty percent (50%) of the
          maximum dollar limitation under Section 415(b)(1)(A)
          of the Code in effect for the calendar year in which
          the determination date (as such term is defined
          above) falls,

     (d)  one (1) of the ten (10) Employees owning (or then
          considered as owning within the meaning of Section
          318 of the Code) the largest interest in a
          Controlled Group Entity whose ownership interest in
          that Controlled Group Entity is at least one-half of
          one percent (0.5%) and whose Section 415
          Compensation from the Controlled Group Entities is
          equal to or greater than the maximum dollar
          limitation under Section 415(c)(1)(A) of the Code in
          effect for the calendar year in which the
          determination date (as such term is defined above)
          falls; provided, however, that if two (2) Employees
          have the same interest in a Controlled Group Entity,
          the Employee whose annual Section 415 Compensation
          from the Controlled Group Entities is greater shall
          be treated as having a larger interest in that
          Controlled Group Entity,

     (e)  a five percent (5%) owner (determined without regard
          to Sections 414(b), (c), (m) and (o) of the Code) of
          a Controlled Group Entity,

     (f)  a one percent (1%) owner (determined without regard
          to Sections 414(b), (c), (m) and (o) of the Code) of
          a Controlled Group Entity whose Section 415
          Compensation from the Controlled Group Entities is
          in excess of one hundred and fifty thousand dollars
          ($150,000);


provided, however, that the Beneficiary of any deceased Employee
or of any deceased former Employee who was included as a key
employee by reason of this Section 14.02 shall also be included
as a key employee; provided, further, that an individual shall
only be included as a key employee to the extent then required by
Section 416(i) of the Code; provided, further, that for purposes
of determining whether an Employee is a key employee, amounts
contributed by the Employers to a salary reduction agreement
which are excludible under Section 125, Section 402(a)(8) or
Section 402(h) of the Code shall be counted in determining that
Employee's Section 415 Compensation.  For purposes of this
Section 14.02, the term "non-key employee" shall mean any
Employee who is not a key employee.  For purposes of this Section
14.02, the term "required aggregation group" shall include:

     (g)  all tax qualified retirement plans maintained by the
          Controlled Group Entities in which a key employee
          (as such term is defined above) is a participant;
          provided, however, that the term "required
          aggregation group" shall also include all tax
          qualified retirement plans previously maintained by
          the Controlled Group Entities but terminated within
          the five (5) year period ending on the determination
          date (as such term is defined above) in which a key
          employee (as such term is defined above) was a
          participant; and

     (h)  any other tax qualified retirement plans maintained
          by the Controlled Group Entities which enable any
          qualified retirement plan described in subsection
          (g) above to meet the requirements of Section
          401(a)(4) or Section 410 of the Code.

For purposes of this Section 14.02, the term "permissive
aggregation group" shall include all tax qualified retirement
plans that are part of a required aggregation group (as such term
is defined above) and any other tax qualified retirement plans
maintained by the Controlled Group Entities if such group will
continue to meet the requirements of Section 401(a)(4) and
Section 410 of the Code.

    Section 14.03.  Accrued Benefits.  For purposes of this
Article XIV, accrued benefits with respect to any Plan Year shall
be determined as of the determination date (as such term is
defined in Section 14.02) for that Plan Year by the Actuary as of
the most recent valuation date which occurred within a
consecutive twelve (12) month period ending on such determination
date; provided, however, that the accrued benefits shall be
adjusted to the extent then required by Section 416 of the Code
to increase the accrued benefits by any rollovers or plan to plan
transfers (other than rollovers or plan to plan transfers which
are initiated by a Member from any tax qualified retirement plan
maintained by an unrelated employer and which are made after
December 31, 1983) made and allocated after the valuation date
but on or before such determination date and by any distributions
made to Members prior to the valuation date during any of the
five (5) consecutive Plan Years immediately preceding the Plan
Year for which the determination as to whether this Plan is a Top-
Heavy Plan is being made (including distributions from a
terminated plan which if not terminated would have been part of a
required aggregation group (as such term is defined in Section
14.02) but excluding death benefits paid to a Member to the
extent such benefits exceed the present value of that Member's
Accrued Benefits as determined in accordance with Section 2.01 on
the date immediately prior to his death) and to reduce the
accrued benefits by any rollovers or plan to plan transfers made
to this Plan after December 31, 1983 but on or before the
valuation date which are initiated by a Member from any tax
qualified retirement plan maintained by an unrelated employer and
by any deductible employee contributions.  The valuation date
used for computing accrued benefits shall be the same valuation
date used for computing the cost of this Plan in accordance with
the minimum funding standards under Section 412 of the Code,
regardless of whether an actuarial valuation is actually
performed for that Plan Year.  The actuarial assumptions used for
purposes of determining the present value of accrued benefits
shall be the same assumptions set forth in Section 2.03;
provided, however, that an interest assumption of five percent
(5%) shall be used. The accrued benefit of a non-key employee
shall be determined under the method, if any, that uniformly
applies for accrual purposes under all tax qualified defined
benefit plans maintained by the Controlled Group Entities or, if
there is no such method, as if such benefit accrued not more
rapidly than the slowest accrual rate then permitted under the
fractional rule of Section 411(b)(1)(C) of the Code.

    Section 14.04.  Vesting Provisions.  Notwithstanding the
provisions of Section 5.01, with respect to any Plan Year in
which this Plan is determined to be a Top-Heavy Plan, a Member's
Accrued Benefit (as determined in accordance with Section 2.01)
shall vest in accordance with the following vesting schedule:

                                 Vested Percentage of
                                 Accrued Benefit Derived
   Years of Service              from Employer Contributions

   less than two (2) years       zero percent (0%)

   two (2) years                 twenty percent (20%)

   three (3) years               forty percent (40%)

   four (4) years                sixty percent (60%)

   five (5) years                eighty percent (80%)

   six (6) years or more         one hundred percent (100%)

provided, however, that if this Plan becomes a Top-Heavy Plan and
subsequently ceases to be such:

     (a)  the vesting schedule shown above shall continue to
          apply but only with respect to those Members who had
          completed three (3) or more years of Service as of the
          last calendar day of the final Top-Heavy Plan Year,
     (b)  the vesting schedule shown above shall continue to
          apply but only with respect to the Accrued Benefits (as
          determined in accordance with Section 2.01) of all
          other Members as of the last calendar day of the final
          Top-Heavy Plan Year, and

     (c)  the vesting schedule in Section 5.01 shall apply to the
          Accrued Benefits (as determined in accordance with
          Section 2.01) of the Members described in subsection
          (b) above which accrue after the last calendar day of
          the final Top-Heavy Plan Year.

    Section 14.05.  Minimum Benefit.  Notwithstanding the
provisions of Section 2.01, the minimum Accrued Benefit (as
determined in accordance with Section 2.01) for each non-key
employee who has completed at least one thousand (1,000) Hours of
Service in this Plan shall be equal to the product resulting from
multiplying:

     (a)  two percent (2%) of his average monthly Section
          415 Compensation during each of his five (5)
          highest-paid consecutive calendar years, by

     (b)  each of his first ten (10) Years of Service after
          December 31, 1983 with respect to Plan Years in
          which this Plan is a Top-Heavy Plan.

    Section 14.06.  Code Section 415 Limitations.  With respect
to any Plan Year in which this Plan is a Top-Heavy Plan and for
Plan Years beginning before January 1, 2000, Section 2.22 and
Section 2.23 shall be read by substituting the number one (1) for
the number one and twenty-five one hundredths (1 25/100ths)
wherever it appears therein; provided, however, that such
substitution shall not have the effect of reducing a Member's
Accrued Benefit (as determined in accordance with Section 2.01)
under any tax qualified defined benefit plan maintained by the
Controlled Group Entities prior to the first (1st) calendar day
of the Plan Year in which this Article XIV initially becomes
applicable.





                           ARTICLE XV

                      INVESTMENT COMMITTEE


    The Chief Executive Officer of the Company shall appoint an
Investment Committee of at least three (3) members to serve at
the pleasure and under the direction of the Company Chief
Executive Officer.

    Any person appointed to be a member of the Investment
Committee shall signify his acceptance in writing to the Chief
Executive Officer of the Company.  Any member of the Investment
Committee may resign by delivering his written resignation to the
Company Chief Executive Officer, and such resignation shall
become effective upon delivery or at any later date specified
therein.

    The members of the Investment Committee shall be paid by the
Employers such compensation as is from time to time determined by
the Company Chief Executive Officer; provided, however, that no
compensation shall be paid to the members of the Investment
Committee from the Trust Fund.  The Employers, except as
otherwise provided by the Act, shall pay or reimburse the
Investment Committee for all expenses reasonably incurred by the
Investment Committee and, except as otherwise provided by the
Act, shall indemnify the Investment Committee and each member
thereof against all loss, liability and expense occasioned by any
act or omission to act taken or determined upon by it or him,
except any such act or omission which is due to willful
misconduct, fraud or lack of good faith.

    The Investment Committee shall have the right to direct the
Trustee to purchase or acquire in any manner securities, stocks,
bonds or any other form of property, real or personal, except as
otherwise provided by the Act or by the Code.  The Investment
Committee shall have the right, from time to time, to review the
securities or other property held by the Trustee in the Trust
Fund and should it seem advisable to the Investment Committee
that such securities or other property be disposed of, it shall
notify the Trustee in writing of its decision.  Upon receipt of
such written notice and consistent with the Trust Agreement, the
Trustee shall dispose of the securities or other property as the
Investment Committee may direct, or in the absence of such
written direction, as the Trustee determines to be in the best
interest of the Trust Fund.  Consistent with the Trust Agreement,
the Investment Committee shall have the power, from time to time,
to direct the Trustee to borrow money from any person (including
the Trustee in its individual capacity, except as otherwise
provided by the Act or by the Code), and it may direct the
Trustee to pledge any securities or other property for the
repayment of the loan.  Consistent with the Trust Agreement, the
Trustee shall not be held responsible for any losses incurred by
the disposal of any securities or other property directed by the
Investment Committee so long as the directions of the Investment
Committee are made in accordance with the terms of this Plan and
are not contrary to Title IV of the Act or prohibitions imposed
under the Code.
