                                  DEFINITIONS


The following terms when used herein shall have the following meaning, unless a

                                   SECTION 5

                                FORMS OF PAYMENT


5.1  Forms of Payment
     ----------------

     The following forms of benefit payments are available under this Plan:

     (a)  Whole Life Annuity:
          ------------------ 

          A Whole Life Annuity shall be payable monthly from the Retirement Date
          to the first of the month preceding death.  The amount of the monthly
          benefit shall equal the monthly Normal, Early or Deferred Retirement
          Benefit, whichever applies.

     (b)  Joint and Survivor Annuity:
          -------------------------- 

          A reduced Joint and Survivor Annuity shall be payable monthly to a
          retired Participant from the Retirement Date or Vested Termination
          Date to the first of the month preceding death.  Following the
          Participant's death, a retirement benefit equal to 50% or 100% of the
          reduced amount payable to the retired Participant shall be payable for
          life to the joint annuitant, if living at the time of the
          Participant's death.  A Participant may elect, before benefits
          commence, which percentage shall be payable to the joint annuitant.

          If the joint annuitant dies after the Participant's retirement income
          begins, the Participant's payments will be in the same reduced amount
          as is otherwise payable under the Joint and Survivor Annuity.  If the
          joint annuitant dies prior to the date as of which the Participant's
          retirement income begins, any election of a form of benefit under this
          Section 5.1(b) shall be automatically canceled.  If the Participant
          dies prior to the date as of which his or her retirement income is to
          begin, the joint annuitant shall not be entitled to receive any
          payments under this Section 5.1(b).  However, a spouse joint annuitant
          may be entitled to a benefit under Section 6.1.

          The Joint and Survivor Annuity shall be Actuarially Equivalent to the
          Participant's retirement benefit payable in the form of a Whole Life
          Annuity.

     (c)  Lump Sum:
          -------- 

          A Lump Sum distribution shall be a single sum payment.  The Lump Sum
          distribution shall be Actuarially Equivalent to the Participant's
          retirement benefit payable in the form of a Whole Life Annuity, and
          shall represent the Participant's entire interest in the Plan.  Lump
          sum distributions may not exceed $10,000.

                                       17

 
5.2  Automatic Form of Benefit
     -------------------------

     Unless a Participant elects otherwise, benefits shall be paid as provided
     below:

     (a)  Married Participants
          --------------------

          Any Participant who is married on his or her Annuity Starting Date or
          Vested Termination Date shall automatically be deemed to have elected
          the 50% Joint and Survivor Annuity option, effective as of such date,
          with his or her spouse on the Annuity Starting Date as the joint
          annuitant (the "Statutory 50% Joint and Survivor Annuity Option").

          A married Participant may reject the Statutory 50% Joint and Survivor
          Annuity Option, or elect a nonspouse joint annuitant pursuant to
          Section 5.3, by filing a written notice with the Committee within
          ninety days prior to his or her Annuity Starting Date.  Such notice
          must specify the form of payment elected, name the non-spouse joint
          annuitant if any, acknowledge the effect of the election, and must be
          signed by the Participant's spouse.  The spouse's signature must be
          notarized or witnessed by a Plan representative.

          A married Participant may file a rejection or joint annuitant election
          notice or revoke any such notice at any time during the ninety-day
          election period immediately preceding the Annuity Starting Date.

     (b)  Other Participants
          ------------------

          An unmarried Participant shall receive his or her retirement benefits
          in the form of a Whole Life Annuity.
 
          An unmarried Participant may reject the Whole Life Annuity option and
          elect either a Joint and Survivor Annuity or a Lump Sum option by
          filing a written notice with the Committee within ninety days prior to
          his or her Annuity Starting Date.  An unmarried Participant may file
          or revoke such a notice at any time during the ninety-day period
          immediately preceding the Annuity Starting Date.

5.3  Limitation on Forms of Payment
     ------------------------------

     A Participant may elect a joint annuitant other than his or her spouse.  A
     Participant must elect a form of payment under which payments will be
     completed within the Participant's and Beneficiary's life times or within
     their life expectancies.  If a Participant elects a joint annuitant other
     than his or her spouse, the percentage selected by the Participant to be
     payable to the joint annuitant cannot exceed the percentage in the table
     set forth in Q&A A-6 of Section 1.401(a)(9)-2 of the proposed Income Tax
     Regulations, determined according to the age difference between the
     Participant and the joint annuitant.

                                       18

 
5.4  Explanation of Forms of Payment
     -------------------------------

     The Committee shall furnish each Participant with a written explanation of
     the terms and conditions of the forms of payment within a reasonable period
     (at least thirty but not more than ninety days) prior to the Participant's
     Annuity Starting Date.

5.5  Directed Rollovers
     ------------------

     (a)  General Rule
          ------------

          A Participant or spouse Beneficiary who is entitled to a lump sum
          benefit pursuant to Section 10.8(c), or who elects a Lump Sum
          distribution pursuant to Section 5.1(c) may direct the Committee to
          pay part or all of the benefit to a trustee or custodian of another
          employer's qualified plan which accepts such directed rollovers or an
          individual retirement account (IRA), subject to the following
          provisions:

          (i)  A Participant or Beneficiary may only direct such a rollover if
               the expected benefit payment during the Plan Year is $200 or
               more.

          (ii) A Participant or Beneficiary may not request a directed rollover
               of an amount distributed due to the minimum required distribution
               provision under Section 10.6(b).

          (iii)The rollover of a distribution may only be directed to one
               qualified plan or IRA.

          (iv) A Participant or Beneficiary may direct the rollover of a portion
               of the distribution and elect to receive the remaining portion of
               a distribution only if the rollover amount is at least $200.

          (v)  A surviving spouse Beneficiary or a former spouse who is an
               alternate payee pursuant to Section 10.9 may direct a rollover
               under the same terms and conditions as a Participant, except that
               such spouse or former spouse may only direct a rollover to an
               IRA.

          (vi) A non-spouse Beneficiary may not direct a rollover pursuant to
               this section.

          (vii)A Participant or Beneficiary provides the information or
               documentation reasonably requested by the Committee.

     (b)  Notice to Participants

          for a directed rollover under this Section 5.5 with a written
          explanation of the directed rollover opportunity and related
          withholding consequences of not choosing a directed rollover within a
          reasonable period (at least thirty (30) but not more than

                                       19

          distribution of small benefits equal to $3,500 or less.

                                       20

 
                                   SECTION 6

                         DEATH AND DISABILITY BENEFITS


6.1  Spouse's Death Benefit
     ----------------------

     In the event a vested Participant dies before commencing to receive
     retirement benefits or Vested Termination Benefits under the Plan, his or
     her spouse shall receive a pre-retirement death benefit provided they were
     married throughout the one year period ending on the date of death.  The
     amount of the spouse's benefit and time of commencement is described below.
     The spouse of a nonvested Participant, or a Participant who has started to
     receive benefits, or a spouse who was married to the Participant less than
     one year, is not entitled to this death benefit.

     (a)  Death Following Early Retirement Date
          -------------------------------------

          If the Participant dies after he or she becomes eligible to elect an
          Early Retirement Date, the spouse's benefit shall be paid monthly from
          the first of the month coinciding with or following the Participant's
          death through the first of the month preceding the spouse's death.
          The benefit shall equal the amount payable to the surviving spouse
          under a 50% Joint and Survivor Annuity form of payment if the
          Participant had commenced receiving retirement benefit payments as of
          the date spouse benefits commence, based upon the Participant's vested
          Accrued Benefit at the date of death.

     (b)  Death Prior to Early Retirement Date
          ------------------------------------

          If the Participant dies prior to becoming eligible to elect an Early
          Retirement Date, the spouse's benefit shall be paid monthly from the
          Participant's earliest Retirement Date (determined as if he or she had
          survived) through the first of the month preceding the spouse's death.
          The benefit shall equal the amount payable to the surviving spouse
          under a 50% Joint and Survivor Annuity form of payment if the
          Participant had Terminated on the date of death, survived to the date
          spouse benefits commence and commenced receiving retirement benefit
          payments on such date.

     Notwithstanding the foregoing, in the event a Participant dies prior to
     Normal Retirement Date, a spouse entitled to benefits under (a) or (b)
     above, may elect prior to the date benefits commence thereunder, to
     postpone commencement of benefits to the first day of any month on or
     before the Participant's Normal Retirement Date determined as if he or she
     had survived.  The benefit payable at such delayed commencement date shall
     be the Actuarial Equivalent of the spouse's death benefit payable at the
     terms specified under (a) or (b) above.

                                       21

 
6.2  Disability Benefits
     -------------------

     A Participant who becomes Disabled shall be deemed to be in Service for
     purposes of vesting and benefit accrual until the earlier of (i) the date
     of recovery from Disability, (ii) an Early Retirement Date elected by the
     Participant, or (iii) Normal Retirement Date.  For purposes of determining
     a Participant's Accrued Benefit, average Earnings for the twelve months
     preceding the date of Termination are deemed to be in effect during
     Disability.

                                       22

 
                                   SECTION 7

                                    VESTING

7.1  Vesting
     -------

     Each Participant shall have a vested, nonforfeitable right to his or her
     Accrued Benefit multiplied by the appropriate vesting percentage in
     accordance with the following table:




     Periods of Service       Percent Vested
     ------------------       --------------
                           
     Less than 5 years              0%
     5 years or more                100%



     In addition, each Participant shall have a 100% nonforfeitable right to his
     or her Accrued Benefit on the first day of the month preceding his or her
     Normal Retirement Date, provided he or she is an Employee on such date.  An
     Employee who Terminates with 0% vested shall be deemed "nonvested."

7.2  Termination Prior to Vesting
     ----------------------------

     (a)  Forfeiture of Service
          ---------------------

          In the event a nonvested Participant incurs a Period of Severance, and
          the number of years in such Period of Severance equals or exceeds five
          consecutive years, his or her Period of Service and Credited Service
          preceding the Severance from Service Date shall be disregarded, and
          any Accrued Benefit earned prior to the Severance from Service Date
          shall be forfeited.  If a vested Participant incurs a Period of
          Severance, all Periods of Service and Credited Service before and
          after the Period of Severance shall be aggregated.

     (b)  Deemed Cash-Out of Accrued Benefit
          ----------------------------------

          If an Employee Terminates at a time when the present value of the
          Employee's vested Accrued Benefit is zero, the Employee shall be
          deemed to have received a distribution of such vested Accrued Benefit,
          and shall no longer be a Participant.  If the individual resumes
          employment with the Employer before incurring a five-consecutive-year
          Period of Severance, the Accrued Benefit will be restored to the
          amount of such Accrued Benefit on the date of the deemed distribution.

7.3  Forfeitures
     -----------

     Any forfeitures arising under this Plan shall be used only to offset future
     Employer contributions and shall not affect any Participant's Accrued
     Benefit.

                                       23

 
                                   SECTION 8

                            LIMITATIONS ON BENEFITS


8.1  Limitation on Benefits
     ----------------------

     (a)  General Rule
          ------------

          In the event the Plan terminates, the benefit of any highly
          compensated employee (and any highly compensated former employee)
          shall be limited to a benefit that is nondiscriminatory under Code
          Section 401(a)(4).

     (b)  Limit on Annual Payments
          ------------------------

          Annual payments to an Employee in the "Restricted Group" (as defined

          Actuarially Equivalent to the sum of the Employee's Accrued Benefit
          and the Employee's other benefits under the Plan (other than a Social
          Security supplement), plus the amount of the payments that the
          Employee is entitled to receive under a Social Security supplement.
          This restriction will not apply if:

          (1)  After payment to an Employee in the Restricted Group of all
               "Benefits" (as defined below), the value of Plan assets equals or
               exceeds 110% of the value of current liabilities, as defined in
               Code Section 412(l)(7),

          (2)  The value of the Benefits for an Employee in the Restricted Group
               is less than 1% (one percent) of the value of current
               liabilities, or

          (3)  The value of the Benefits for an Employee in the Restricted Group
               does not exceed the amount described in Code Section

               Section 72(p)(2)(A), 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.

                                       24

 
     (d)  Regulatory Authority
          --------------------

          This Section 81 is intended to comply with Treasury regulation
          (S)1.401(a)(4)-5(b), and shall be superseded to the extent any
          provision of such regulation in final form conflicts with the
          limitations stated herein.

8.2  Maximum Annual Benefit Payable Under the Plan
     ---------------------------------------------

     For purposes of this Section 8.2, the Employer and any Affiliated Companies
     shall be considered a single employer, to the extent required by the Code.

     (a)  Primary Rule
          ------------

          Notwithstanding any other Plan provision to the contrary, the annual
          Employer provided benefit payable to or on behalf of a Participant
          under the Plan (after any adjustments required under the Plan to
          reflect commencement of benefits other than at Normal Retirement Date,
          an optional form of payment or death benefit coverage) after 1982
          shall not exceed the lesser of:

             (i)  $90,000 (adjusted in accordance with this Section 8.2) or, if
                  greater, the Participant's current Accrued Benefit on December
                  31, 1982, or

             (ii) the Participant's average annual Compensation from the
                  Employer for the consecutive calendar years (not in excess of
                  three such years) during which he was an active Participant in
                  the Plan and for which such average is highest.

     (b)  Cost-of-Living Adjustment
          -------------------------

          The $90,000 limit prescribed above shall be automatically adjusted for
          cost-of-living increases, to the maximum permissible dollar limitation
          determined by the Commissioner of Internal Revenue.  The dollar amount
          applicable in computing the benefit payable to any Participant shall
          be the dollar amount in effect for the calendar year in which the
          benefit commences.  For 1992, the limit is $112,221.

     (c)  Adjustment for Early or Late Retirement
          ---------------------------------------

          For purposes of 8.2 and 8.3, if the Participant's benefit commences
          before Social Security Retirement Age, the limit prescribed in Section
          8.2(a)(1) shall be Actuarially reduced to reflect such early
          commencement.  If the Participant's benefit commences after Social
          Security Retirement Age, the limit prescribed in Section 8.2(a)(1)
          shall be Actuarially increased for purposes of Section 8.2 and Section
          8.3 to reflect such late commencement.

                                       25

          Participant under the Plan is not in the form of an Annual Benefit as
          described below, the benefit considered to be payable to a Participant
          under the Plan for purposes of Sections 8.2 and 8.3 shall be
          Actuarially adjusted to the extent required under Section 415(b)(2) of
          the Code.  For purposes of the foregoing, Annual Benefit means the
          benefit payable annually in the form of a straight life annuity
          without ancillary benefits or in the Statutory 50% Joint and Survivor
          Annuity Option.

     (e)  Interest Rate
          -------------

          Any Actuarial adjustments under this Section 8.2 shall be based on the
          Actuarial factors applicable for comparable purposes under the Plan on
          the applicable date, except that

          (i)  the interest rate assumption for purposes of adjusting the
               $90,000 limitation for benefits commencing before Social Security
                                                          ------                
               Retirement Age shall be the greater of 5% or the Plan rate; and
                                           -------                            

          (ii) the interest rate assumption for purposes of adjusting the
               $90,000 limitation for benefits commencing after Social Security
                                                          -----                
               Retirement Age shall be the lesser of 5% or the Plan rate.
                                           ------                        

     (f)  Special Provisions Regarding Participants With Fewer Than Ten Years of
          ----------------------------------------------------------------------
          Participation or Service
          ------------------------

          In the case of any Participant who participated in the Plan for fewer
          than ten years, the maximum dollar benefit otherwise applicable under
          Section 8.2(a)(i) shall be multiplied by a fraction whose numerator is
          the Participant's years of participation in the Plan (including
          fractions thereof, but not less than one) and whose denominator is
          ten.

          In the case of any Participant who was employed by the Employer for
          fewer than ten years, the maximum benefit otherwise applicable under
          Sections 8.2(a)(ii) and 8.3 shall be multiplied by a fraction whose
          numerator is the Participant's years of employment with the Employer
          (including fractions thereof, but not less than one) and whose
          denominator is ten.

     (g)  Transition Rule
          ---------------

          The limitations of this Section 8.2 shall not reduce a Participant's
          annual benefit to less than his or her Accrued Benefit as of December
          31, 1986, disregarding any change in the terms of the Plan and any
          cost-of-living adjustments after May 5, 1986.

                                       26

 
     (h)  Aggregation With Other Defined Benefit Plans
          --------------------------------------------

          If a Participant also participates in any other defined benefit
          pension plan maintained by the Employer, the provisions of Section 8.2
          and 8.3 shall be applied on an aggregate basis to the benefits payable
          under this Plan and each such other plan.  Any reduction in the
          aggregate benefits payable under this Plan and any such other plan due
          to the application of this Section shall be made on a pro-rata basis.

8.3  Additional Limitation Relating to Defined Contribution Plans
     ------------------------------------------------------------

     (a)  Primary Rule
          ------------

          For Participants who participate in this Plan and a defined
          contribution plan maintained by the Employer, the sum of (1) and (2)
          below for any calendar year may not exceed 1.0.

          (i)  The defined benefit plan fraction for any year is equal to the
               quotient of (i) divided by (ii) below expressed as a fraction:

               (i)  The projected annual benefit (determined by projecting
                    service, but not Earnings, to normal retirement age) of the
                    Participant under the Plan determined as of the close of the
                    year.

               (ii) The lesser of:  (a) 1.25 multiplied by the limitation
                    determined under Section 8.2(a)(1) in effect for such year,
                    or (b) 1.4 multiplied by the limitation determined under
                    Section 8.2(a)(2) (generally 100% of the Participant's
                    average annual Compensation).

          (ii) The defined contribution plan fraction for any year is equal to
               the quotient of (i) divided by (ii) below expressed as a
               fraction:

               (i)  The sum of the "annual additions" to the Participant's
                    accounts for the current year, as of the close of the year,
                    and for all prior years.

               (ii) The sum of the lesser of the following amounts for such year
                    and for each prior year of service with the Employer
                    (regardless of whether a plan was in existence during those
                    years):  (a) 1.25 multiplied by the dollar limitation in
                    effect for defined contribution plans under Section 415 of
                    the Code for such year, or (b) 1.4 multiplied by 25% of a
                    Participant's Compensation for such year.

     (b)  Remedy
          ------

          If such sum exceeds 1.0, the benefit under this defined benefit Plan
          shall be reduced to the extent necessary to satisfy the limitations of
          this section.

                                       27

 
                                   SECTION 9

                              TOP HEAVY PROVISIONS

9.1  Scope
     -----

     Notwithstanding any Plan provision to the contrary, for any Plan Year in
     which the Plan is Top Heavy within the meaning of Section 416(g) of the
     Code, the provisions of this Section 9 shall govern to the extent they
     conflict with or specify additional requirements to the Plan provisions
     governing Plan Years which are not Top Heavy.

9.2  Top Heavy Status
     ----------------

     (a)  Top Heavy
          ---------

          This Plan shall be "Top Heavy" if, as of the Determination Date, (1)
          the sum of the Aggregate Accounts of Key Employees, or (2) the Present
          Value of Accrued Benefits of Key Employees under this Plan and any
          plan of an Aggregation Group, exceeds 60% of the Aggregate Accounts or
          the Present Value of Accrued Benefits of all Participants under this
          Plan and any plan of an Aggregation Group.

          The Present Value of Accrued Benefits and/or Aggregate Account balance
          of a Participant who was previously a Key Employee but is no longer a
          Key Employee (or his or her Beneficiary), shall not be taken into
          account for purposes of determining Top Heavy status.  Further, a
          Participant's Present Value of Accrued Benefits and/or Aggregate
          Account balance shall not be taken into account if he or she has not
          performed services for the Affiliated Companies during the five year
          period ending on the Determination Date.

     (b)  Super Top Heavy
          ---------------

          This Plan shall be "Super Top Heavy" if, as of the Determination Date,
          (1) the sum of the Aggregate Accounts of Key Employees, or (2) the
          Present Value of Accrued Benefits of Key Employees under this Plan and
          any plan of an Aggregation Group, exceeds 90% of the Aggregate
          Accounts or the Present Value of Accrued Benefits of all Participants
          under this Plan and any plan of an Aggregation Group.

     (c)  Determination Date
          ------------------

          Whether the Plan is Top Heavy for any Plan Year shall be determined as
          of the Determination Date.  "Determination Date" means (a) the last
          day of the preceding Plan Year, or (b) in the case of the first Plan
          Year, the last day of such Plan Year.

                                       28

 
     (d)  Valuation Date
          --------------

          "Valuation Date" means, for purposes of determining Top Heaviness, the
          Determination Date.

     (e)  Aggregate Account
          -----------------

          "Aggregate Account" means, with respect to a Participant, his or her
          adjusted account balance in a defined contribution plan, as determined
          under the top heavy provisions of such plan.

     (f)  Present Value of Accrued Benefits
          ---------------------------------

          "Present Value of Accrued Benefits" means the sum of:

          (i)  the Actuarial Equivalent present value of the accrued normal
               retirement benefit under the Plan as of the Valuation Date, and

          (ii) distributions prior to the Valuation Date, made during the
               Plan Year that contains the Determination Date and the four
               preceding Plan Years.  Unrelated rollovers or transfers from 
               this plan shall be considered distributions.  A related 
               rollover or transfer from this Plan shall not be considered
               a distribution.

          An unrelated rollover or transfer is one which is both initiated by
          the Employee and made between plans of different employers.  A related
          rollover or transfer is one which is either not initiated by the
          Employee or made between plans of the same employer.

     (g)  Key Employee
          ------------

          "Key Employee" means an Employee or former Employee (and his or her
          Beneficiaries) who, at any time during the Plan Year containing the
          Determination Date or any of the four preceding Plan Years, is
          included in one of the following categories as within the meaning of
          Section 416(i) of the Code and regulations thereunder.

          (i)  an officer of the Employer whose annual aggregate Compensation
               from the Affiliated Companies exceeds 50% of the dollar
               limitation under Section 415(c)(1)(A) of the Code ($56,111 for
               the Plan Year ending in 1992), provided that no more than 50
               Employees shall be considered officers, or if less, the greater
               of 10% of the Employees or 3,

          (ii) one of the ten Employees owning the largest interest in the
               Employer who owns more than a 0.5% interest of the Employer, and
               whose annual aggregate Compensation from the Affiliated Companies
               exceeds the dollar limitation under Section 415(c)(1)(A) of the
               Code ($30,000 for the Plan Year ending in 1992),

                                       29

 
           (iii)an Employee who owns more than 5% of the Employer, or

           (iv) an Employee who owns more than 1% of the Employer with annual
                aggregate Compensation from the Affiliated Companies that 
                exceeds $150,000.

     (h)  Aggregation Group
          -----------------

          "Aggregation Group" means the group of plans that must be considered
          as a single plan for purposes of determining whether the plans within
          the group are Top Heavy (Required Aggregation Group), or the group of
          plans that may be aggregated for purposes of Top Heavy testing
          (Permissive Aggregation Group).  The Determination Date for each plan
          must fall within the same calendar year in order to aggregate the
          plans.

          (i)  The Required Aggregation Group includes each plan of the
               Affiliated Companies in which a Key Employee is a participant in
               the Plan Year containing the Determination Date or any of the
               four preceding Plan Years, and each other plan of the Affiliated
               Companies which, during this period, enables any plan in which a
               Key Employee participates to meet the minimum participation
               standards or nondiscriminatory contribution requirements of Code
               Sections 401(a)(4) and 410.

          (ii) A Permissive Aggregation Group may include any plan sponsored
               by an Affiliated Company, provided the group as a whole continues
               to satisfy the minimum participation standards and
               nondiscriminatory contribution requirements of Code Sections
               401(a)(4) and 410.

          Each plan belonging to a Required Aggregation Group shall be deemed
          Top Heavy or non-Top Heavy in accordance with the group's status.  In
          a Permissive Aggregation Group that is determined Top Heavy only those
          plans that are required to be aggregated shall be Top Heavy.  In a
          Permissive Aggregation Group that is not Top Heavy, no plan in the
          group shall be Top Heavy.

9.3  Minimum Benefit
     ---------------

     (a)  General Rule
          ------------

          For any Top Heavy Plan Year, a non-Key Employee who completes a Year
          of Service shall have an Accrued Benefit at least equal to the minimum
          benefit described herein.  The minimum Accrued Benefit at any point in
          time equals the lesser of:

          (i)  two percent multiplied by Top Heavy Years of Service, or

          (ii) twenty percent,

                                       30

 
          multiplied by such Participant's "average Compensation."  "Average
          Compensation" means a Participant's average Compensation for the five
          consecutive years when such Participant had the highest aggregate
          Compensation from the Employer.  However, Compensation received for
          non-Top Heavy Plan Years shall be disregarded.  The benefit described
          herein is expressed as an annual benefit in the form of a single life
          annuity (with no ancillary benefits), commencing at normal retirement
          age.

          A non-Key Employee shall not be denied this minimum benefit because he
          or she was not employed on a specified date, failed to make any
          mandatory Employee contribution, or failed to earn a specified amount
          of Compensation.

     (b)  Special Two Plan Rule
          ---------------------

          Where this Plan and a defined contribution plan belong to an
          Aggregation Group that is determined Top Heavy, the Employer shall not
          be required to provide the minimum benefit under (a) above on behalf
          of any non-Key Participant who also participates in the defined
          contribution plan if the Employer contributions and forfeitures under
          the defined contribution plan equal 5% of each non-Key Participant's
          Compensation.

9.4  Benefit Limitation
     ------------------

     For any Top Heavy Plan Year in which the Employer does not make the extra
     minimum allocation provided below, 1.0 shall replace the 1.25 factor found
     in the denominators of the defined benefit and defined contribution plan
     fractions for purposes of calculating the combined limitation on benefits
     under a defined benefit and defined contribution plan pursuant to Section
     415(e) of the Code (see Section 8.3).

     If this Plan is Top Heavy, but is not Super Top Heavy, the above referenced
     fractions shall remain unchanged provided the Employer provides an extra
     minimum Accrued Benefit for each non-Key Employee.  The extra benefit (in
     addition to the minimum benefit set forth in Section 9.3) shall equal the
     lesser of:

     (i)  one percent multiplied by Top Heavy years of Service, or

     (ii) ten percent,

     multiplied by such Participant's "average Compensation", as defined in
     Section 9.3.

9.5  Vesting
     -------

     (a)  Top Heavy Schedule
          ------------------

          For any Top Heavy Plan Year, each Participant who completes an Hour of
          Service in such Year shall become vested and have a nonforfeitable
          right to retirement benefits he or she has earned under the Plan in
          accordance with the following table:

                                       31

 



          Periods of Service    Vesting Percentage
          ------------------    ------------------
                             
          Less than 2 Years           0%
               2 Years               20%
               3 Years               40%
               4 Years               60%
               5 Years              100%


          Provided, however, that a Participant's vesting percentage shall not
          be less than the percentage determined under the table in Section 7.1.

     (b)  Return to Non-Top Heavy Status
          ------------------------------

          If the Plan becomes Top Heavy and ceases to be Top Heavy in any
          subsequent Plan Year, the vesting schedule shall automatically revert
          to the vesting schedule in effect before the Plan became Top Heavy.
          Such reversion shall be treated as a Plan amendment pursuant to the
          terms of the Plan, and shall not cause a reduction of any
          Participant's nonforfeitable interest in the Plan on the date of such
          amendment.

          A Participant with three or more Years of Service with the Employer as
          of the end of the election period, may elect to remain covered by the
          Top Heavy vesting schedule.  The Participant's election period shall
          commence on the adoption date of the amendment and shall end 60 days
          after the latest of:

          (i)  the adoption date of the amendment,

          (ii) the effective date of the amendment, or

          (iii)the date the Participant receives written notice of the
               amendment from the Committee.

                                       32

               provision of the Plan;

          (vii)Delegate and allocate specific responsibilities and duties

     (c)  General Authority
          -----------------

          The Committee shall have all powers necessary or appropriate to carry
          out its duties, including the discretionary authority to interpret the
          provisions of the Plan and the facts and circumstances of claims for
          benefits.  Any interpretation or construction of or action by the
          Committee with respect to the Plan and its administration shall be

     ------------------------

     (a)  Conditions of Payment
          ---------------------

          Benefit payments under the Plan shall not be payable prior to the
          fulfillment of the following conditions:

          (i)  The Committee has been furnished with such applications, proofs
               of birth or death, address, form of benefit election, spouse
               consent if required, and other information the Committee deems

          The payment of benefits shall commence no later than 60 days after the
          retirement date specified herein for commencement of such benefits,
          provided that payments shall not commence later than the April 1
          following the calendar year in which the Participant reaches age
          70-1/2.

          In no event shall payments commence in a form other than the automatic
          form described in Section 5.2 prior to the Participant's Normal
          Retirement Age if the Actuarially Equivalent present value of the

          applicable date shall be made and monthly payments commenced.

                                       35

 
10.7 Appeal Procedure
     ----------------

     (a)  Submission of Claim
          -------------------

          A claim for benefit payment shall be considered filed when an
          application form is submitted to the Committee.

     (b)  Notice of Denial
          ----------------

          Any time a claim for benefits is wholly or partially denied, the
          Participant or Beneficiary (hereinafter "Claimant") shall be given
          written notice of such action within 90 days after the claim is filed,
          unless special circumstances require an extension of time for
          processing. (If there is an extension, the Claimant shall be notified
          of the extension and the reason for the extension within the initial
          90 day period. The extension shall not exceed 180 days after the
          claim is filed.) Such notice will indicate the reason for denial, the
          pertinent provisions of the Plan on which the denial is based, an
          explanation of the claims appeal procedure set forth herein, and a
          description of any additional material or information necessary to
          perfect the claim and an explanation of why such material or
          information is necessary.

     (c)  Right to Request Review
          -----------------------

          Any person who has had a claim for benefits denied by the Committee,
          who disputes the amount of benefit payment determined by the
          Committee, or who is otherwise adversely affected by action of the
          Committee, shall have the right to request review by the Committee.
          Such request must be in writing, and must be made within 60 days after
          such person is advised of the Committee's action. If written request
          for review is not made within such 60-day period, the Claimant shall
          forfeit his or her right to review.  The Claimant or a duly authorized
          representative of the Claimant may review all pertinent documents and
          submit issues and comments in writing.

     (d)  Review of Claim
          ---------------

          The Committee shall then review the claim.  It may hold a hearing if
          it deems it necessary and shall issue a written decision reaffirming,
          modifying or setting aside its former action within 60 days after
          receipt of the written request for review, or 120 days if special
          circumstances, such as a hearing, require an extension.  The Claimant
          shall be notified in writing of any such extension within 60 days
          following the request for review.  A copy of the decision shall be
          furnished to the Claimant.  The decision shall set forth its reasons
          and pertinent Plan provisions on which it is based.  The decision
          shall be final and binding upon the Claimant and the Committee and all
          other persons involved.

                                       36

 
10.8 Plan Administration - Miscellaneous
     -----------------------------------

     (a)  Limitations on Assignments
          --------------------------

          Benefits under the Plan may not be assigned, sold, transferred, or
          encumbered, and any attempt to do so shall be void.  The interest of a
          Participant in benefits under the Plan shall not be subject to debts
          or liabilities of any kind and shall not be subject to attachment,
          garnishment or other legal process, except as provided in Section 10.8
          relating to Domestic Relations Orders, or otherwise permitted by law.

     (b)  Masculine and Feminine, Singular and Plural
          -------------------------------------------

          Whenever used herein, pronouns shall include the opposite gender, and
          the singular shall include the plural and the plural shall include the
          singular whenever the context shall plainly so require.

     (c)  Small Benefits
          --------------

          In cases where the Actuarially Equivalent present value of a vested or
          payable benefit is less than or equal to the maximum permissible
          amount under the Code which may be distributed without the consent of
          a Participant or his or her spouse (in 1990, this amount was $3,500),
          the Committee shall direct such present value be paid in a lump sum
          distribution as soon as practical following termination and prior to
          the Annuity Starting Date.  No payment shall be made pursuant to this
          Section 10.8(c) after a Participant's Annuity Starting Date unless the
          Participant and his spouse consent to such payment in a written
          document filed with the Committee.

     (d)  No Additional Rights
          --------------------

          No person shall have any rights in or to the Trust Fund, or any part
          thereof, or under the Plan, except as, and only to the extent,
          expressly provided for in the Plan.  Neither the establishment of the
          Plan, the accrual of benefits under the Plan nor any action of the
          Employer or the Committee shall be held or construed to confer upon
          any person any right to be continued as an Employee, or, upon
          dismissal, any right or interest in the Trust Fund other than as
          herein provided.  The Employer expressly reserves the right to
          discharge any Employee at any time.

     (e)  Governing Law
          -------------

          This Plan shall be construed in accordance with applicable federal law
          and the laws of the State of Washington, wherein venue shall lie for
          any dispute arising hereunder.

                                       37

 
     (f)  Disclosure to Participants
          --------------------------

          Each Participant shall be advised of the general provisions of the
          Plan and, upon written request addressed to the Committee, shall be
          furnished any information requested regarding the Participant's
          status, rights and privileges under the Plan as may be required by
          law.

     (g)  Income Tax Withholding Requirements
          -----------------------------------

          Any retirement benefit payment made under the Plan shall be subject to
          any applicable income tax withholding requirements.  For this purpose,
          the Committee shall provide the Trustee with any information the
          Trustee needs to satisfy such withholding obligations and with any
          other information that may be required by regulations promulgated
          under the Code.

     (h)  Severability
          ------------

          If any provision of this Plan shall be held illegal or invalid for any
          reason, such determination shall not affect the remaining provisions
          of this Plan which shall be construed as if said illegal or invalid
          provision had never been included.

     (i)  Facility of Payment
          -------------------

          In the event any benefit under this Plan shall be payable to a person
          who is under legal disability or is in any way incapacitated so as to
          be unable to manage his or her financial affairs, the Committee may
          direct payment of such benefit to a duly appointed guardian, committee
          or other legal representative of such person, or in the absence of a
          guardian or legal representative, to a custodian for such person under
          a Uniform Gifts to Minors Act or to any relative of such person by
          blood or marriage, for such person's benefit.  Any payment made in
          good faith pursuant to this provision shall fully discharge the
          Employer and the Plan of any liability to the extent of such payment.

     (j)  Correction of Errors
          --------------------

          Any Employer contribution to the Trust Fund made under a mistake of
          fact (or investment proceeds of such contribution if a lesser amount)
          shall be returned to the Employer within one year after payment of the
          contribution.  In the event an incorrect amount is paid to a
          Participant or Beneficiary, any remaining payments may be adjusted to
          correct the error.  The Committee may take such other action it deems
          necessary and equitable to correct any such error.

10.9 Domestic Relations Orders
     -------------------------

     Notwithstanding any Plan provisions to the contrary, benefits under the
     Plan may be paid to someone other than the Participant, Beneficiary or
     joint annuitant, pursuant to a Qualified Domestic Relations Order, in
     accordance with Section 414(p) of the Code.  A

                                       38

 
     Qualified Domestic Relations Order is a judgement, decree, or order
     ("Order") (including approval of a property settlement agreement) that:

     (a)  relates to the provision of child support, alimony payments or marital
          property rights to a spouse, former spouse, child or other dependent
          of a Participant;

     (b)  is made pursuant to a state domestic relations law (including a
          community property law);

     (c)  creates or recognizes the existence of an alternate payee's right to,
          or assigns to an alternate payee the right to, receive all or a
          portion of the benefits payable to a Participant under the Plan;

     (d)  specifies the name and last known address of the Participant and each
          alternate payee;

     (e)  specifies the amount or method of determining the amount of benefit
          payable to an alternate payee;

     (f)  specifies the number of payments or period during which payments are
          to be made;

     (g)  names each plan to which the order applies;

     (h)  does not require any form, type or amount of benefit not otherwise
          provided under the Plan; and

     (i)  does not conflict with a prior Domestic Relations Order that meets the
          requirements of this section.

     Payments to an alternate payee pursuant to a Qualified Domestic Relations
     Order may commence after the Participant becomes vested and on or after the
     earlier of (a) the date the Participant attains age 55, or (b) the date the
     Participant is eligible to elect to receive a Vested Termination Benefit.
     The Alternate Payee may elect any form of payment available under the Plan
     at the time benefit payments commence other than a joint and survivor
     annuity, provided that a lump sum form of payment is available only if the
     Alternate Payee's benefit does not exceed $10,000.

     The Committee shall determine whether an order meets the requirements of
     this section within a reasonable period after receiving an order.  The
     Committee shall notify the Participant and any alternate payee that an
     order has been received and with respect to benefits which are in pay
     status shall establish a separate account under the Plan for any alternate
     payee pending determination that an order meets the requirements of this
     section.  If within eighteen months after such separate account is
     established the order has not been determined to be a qualified Order, the
     amount in the separate account shall be distributed to the individual who
     would have been entitled to such amount if there had been no order.

                                       39

 
10.10  Plan Qualification
       ------------------

       Any modification or amendment of the Plan may be made retroactive, as
       necessary or appropriate, to establish and maintain a "qualified plan" 
       pursuant to Section 401 of the Code, and ERISA and regulations 
       thereunder and the exempt status of the Trust Fund under Section 501 of
       the Code.

10.11  Deductible Contribution
       -----------------------

       Notwithstanding anything herein to the contrary, any contribution by 
       the Employer to the Trust Fund is conditioned upon the deductibility of
       the contribution by the Employer under the Code and, to the extent any 
       such deduction is disallowed, the Employer may within one year following
       a final determination of the disallowance, demand repayment of such 
       disallowed contribution and the Trustee shall return such contribution 
       less any losses attributable thereto to the Employer within one year 
       following the disallowance.

10.12  Payment of Benefits Through Purchase of Annuity Contract
       --------------------------------------------------------

       In lieu of paying benefits directly from the Trust Fund to a Participant
       or his Beneficiary, the Trustee may purchase, with Trust Fund assets, an
       individual annuity contract from an insurance company rated A+ by A.M. 
       Best Company, Inc. which, as far as possible, provides benefits equal 
       to (or Actuarially Equivalent to) those provided in the Plan for such 
       Participant or Beneficiary, but provides no optional form of retirement
       income or benefit which would not be permitted under the Plan, 
       whereupon the liability of the Trust Fund and of the Plan will cease and
       terminate with respect to such benefits that are so purchased and for 
       which the premiums are duly paid.  Such an individual annuity contract 
       may be purchased by the Trustee on a single-premium basis or on the 
       basis of annual premiums Payable over a period of years and may be 
       purchased at any time on or after the Participant's Vested Termination 
       Date, Retirement Date or death to provide the benefits due under the 
       Plan to the Participant or Beneficiary on or after the date of such 
       purchase.

       Any annuity contract distributed by the Trustee to a Participant or
       Beneficiary under the provisions of the Plan shall bear on the face 
       thereof the designation "NOT TRANSFERABLE", and such contract shall 
       contain a provision to the effect that the contract may not be sold, 
       assigned, discounted or pledged as collateral for a loan or as security
       for the performance of an obligation or for any other purpose to any 
       person other than the issuer thereof.

                                       40

 
                                   SECTION 11

                           AMENDMENT AND TERMINATION


11.1 Amendment General
     -----------------

     The Employer shall have the right to amend, terminate, or partially
     terminate this Plan by action of its Board of Directors at any time subject
     to any advance notice or other requirements of ERISA.

11.2 Amendment - Consolidation or Merger
     -----------------------------------

     In the event the Plan's assets and liabilities are merged into, transferred
     to or otherwise consolidated with any other retirement plan, then such must
     be accomplished so as to ensure that each Participant would (if the other
     retirement plan then terminated) receive a benefit immediately after the
     merger, transfer or consolidation, which is equal to or greater than the
     benefit the Participant would have been entitled to receive immediately
     before the merger, transfer or consolidation (as if the Plan had then
     terminated).  This provision shall not be construed as limiting the powers
     of the Employer to appoint a successor Trustee.

11.3 Termination of the Plan
     -----------------------

     The termination of the Plan shall not cause or permit any part of the Trust
     Fund to be diverted to purposes other than for the exclusive benefit of the
     Participants, or cause or permit any portion of the Trust Fund to revert to
     or become the property of the Employer at any time prior to the
     satisfaction of all liabilities with respect to the Participants.

     Upon termination of this Plan, the Committee shall continue to act for the
     purpose of complying with the preceding paragraph and shall have all power
     necessary or convenient to the winding up and dissolution of the Plan as
     herein provided.  While so acting, the Committee shall be in the same
     status and position with respect to other persons as if the Plan remained
     in existence.

11.4 Allocation of the Trust Fund on Termination of Plan
     ---------------------------------------------------

     In the event of a complete Plan termination, the right of each Participant
     to benefits accrued to the date of such termination that would be vested
     under the provisions of the Plan in the absence of such termination shall
     continue to be vested and nonforfeitable; and the right of each Participant
     to any other benefits accrued to the date of termination shall be fully
     vested and nonforfeitable to the extent then funded under the priority
     rules set forth in Section 4044 of ERISA.  In any event, a Participant or a
     Beneficiary shall have recourse only against Plan assets for the payment of
     benefits thereunder, subject to any applicable guarantee provisions of
     Title IV of ERISA.  The Committee shall direct the Trustee to allocate
     Trust assets to those affected Participants to the extent and in the order
     of preference set forth in Section 4044 of ERISA.  The assets so allocated
     shall be

                                       41

 
     distributed, as determined by the Committee, either wholly or in part by
     purchase of nontransferable annuity contracts or lump-sum payments.  If
     Trust Fund assets as of the date of Plan termination exceed the amounts
     required under the priority rules set forth in Section 4044 of ERISA, such
     excess shall, after all liabilities of the Plan have been satisfied, revert
     to the Employer to the extent permitted by applicable law.

     If at any time the Plan is terminated with respect to any group of
     Participants under such circumstances as to constitute a partial Plan
     termination within the meaning of Section 411(d)(3) of the Code, each
     affected Participant's right to benefits that have accrued to the date of
     partial termination that would be vested under the provisions of the Plan
     in the absence of such termination shall continue to be so vested; and the
     right of each affected Participant to any other benefits accrued to the
     date of such termination shall be vested to the extent assets would be
     allocable to such benefits under the priority rules set forth in Section
     4044 of ERISA in the event of a complete Plan termination.  In any event,
     affected Participants shall have recourse only against Plan assets for
     payment of benefits thereunder, subject to any applicable guarantee
     provisions of Title IV of ERISA.  Subject to the foregoing, the vested
     benefits of such Participants shall be payable as though such termination
     had not occurred; provided, however, that the Committee, in its discretion,
     subject to any necessary governmental approval, may direct that the amounts
     held in the Trust Fund that are allocable to the Participants as to whom
     such termination occurred be segregated by the Trustee as a separate plan.
     The assets thus allocated to such separate plan shall be applied for the
     benefit of such Participants in the manner described in the preceding
     paragraph.

                                       42

 
                                   SECTION 12

                                    FUNDING


12.1 Contributions to the Trust
     --------------------------

     As a part of this Plan the Employer shall maintain a Trust.  From time to
     time, the Employer shall make such contributions to the Trust as the
     Committee determines, with the advice of its actuary, are required to
     maintain the Plan on a sound actuarial basis.

12.2 Trust Fund for Exclusive Benefit of Participants
     ------------------------------------------------

     The Trust is for the exclusive benefit of Participants.  Except as provided
     in Sections 10.7(j) (Correction of Errors), 10.9 (Domestic Relations
     Orders) and 10.11 (Deductible Contributions), no portion of the Trust shall
     be diverted to purposes other than this or revert to or become the property
     of the Employer at any time prior to the satisfaction of all liabilities
     with respect to the Participants.

12.3 Disposition of Credits and Forfeitures
     --------------------------------------

     In no event shall any credits or forfeitures which may arise under the Plan
     be used to increase benefits under the Plan.

                                  FIDUCIARIES


13.1 Limitation of Liability of the Employer and Others
     --------------------------------------------------

     No Participant shall have any claim against the Employer, or the Committee,
     or against their directors, officers, members, agents or representatives,
     for any benefits under the Plan, and such benefits shall be payable solely
     from the Trust; nor, to the extent permitted by law, shall the Employer,
     the Committee or their directors, officers, members, agents or
     representatives incur any liability to any person for any action taken or
     suffered or omitted to be taken by them under the Plan in good faith.

13.2 Indemnification of Fiduciaries
     ------------------------------

     In order to facilitate the recruitment of competent fiduciaries, the
     Employer adopting this Plan agrees to provide the indemnification as
     described herein.  This provision shall apply to Employees who are
     considered Plan fiduciaries including without limitation, Committee
     members, any agent of the Committee, or any other officers, directors or
     Employees.  Notwithstanding the preceding, this provision shall not apply
     and indemnification will not be provided for any Trustee or Investment
     Manager appointed as provided in this Plan.

13.3 Scope of Indemnification
     ------------------------

     The Employer agrees to indemnify an Employee fiduciary as described above
     for all acts taken in good faith in carrying out his or her
     responsibilities under the terms of this Plan or other responsibilities
     imposed upon such fiduciary by ERISA.  This indemnification for all acts is
     intentionally broad but shall not provide indemnification for embezzlement
     or diversion of Plan assets for the benefit of the Employee fiduciary.  The
     Employer agrees to indemnify Employee fiduciaries described herein for all
     expenses of defending an action by a Participant, Beneficiary or government
     entity, including all legal fees for counsel selected with the consent of
     the Employer and other costs of such defense.  The Employer will also
     reimburse an Employee fiduciary for any monetary recovery in any court or
     arbitration proceeding.  In addition, if the claim is settled out of court
     with the concurrence of the Employer, the Employer will indemnify an
     Employee fiduciary for any monetary liability under said settlement.  The
     Employer shall have the right, but not the obligation, to conduct the
     defense of such persons in any proceeding to which this Section 13.3
     applies.  The Employer may satisfy its obligations under this Section 13.3
     in whole or in part through the purchase of a policy or policies of
     insurance providing equivalent protection.
