          section 3401(a) for purposes of income tax withholding at the source
          but determined without regard to any rules that limit the remuneration
          included in wages based on the nature or location of the employment or
          the services performed. 

     (3)  For purposes of determining whether an individual is a Highly-
          Compensated Employee, and for purposes of applying the limitations of
          Sections 8.1, 8.2 and 8.3, Compensation means an Employee's
          Compensation, as described in Section 2.1(i)(2), increased by amounts
          excluded from wages by reason of an Employee's election to reduce
          wages in lieu of benefits under a cafeteria plan under Code section
          125 or a cash or deferred arrangement under Code section 401(k);
          provided, however, that in lieu of the definition of Compensation set
          forth in this paragraph (3), the Committee may elect any alternative
          definition of Compensation permitted under Treasury regulations for
          purposes of applying the limitations described in Sections 8.1, 8.2
          and 8.3. 

     The Compensation of each Employee that may be taken into account under the
     Plan shall not exceed the "applicable dollar amount" of an Employee's
     Compensation. For purposes of this Section 2.1(i), the term "applicable
     dollar amount" means the maximum annual compensation limit which is
     $150,000 effective January 1, 1994 (and was $200,000 effective January 1,
     1989), as provided for in Code section 401(a)(17) and as such amount may be
     adjusted or changed from year to year in accordance with the adjustment
     provisions of Code section 401(a)(17), or as a result of changes to the
     dollar amount set forth in Code section 401(a)(17). Additionally, for
     purposes of applying the limitation in the two preceding sentences, the
     rules of Code section 414(q)(6) shall




                                        3
   9

     apply to the determination of an Employee's annual Compensation. In the
     case of an Employee who is a 5% owner as defined in Code section
     416(i)(1)(b)(iii) or one of the ten Highly Compensated Employees paid the
     greatest Compensation during a Plan Year, then for such Plan Year the
     "applicable dollar amount" shall be applied to the aggregate compensation
     of the Employee, his spouse, and any of his lineal descendants who have not
     attained age 19 before the end of the Plan Year. If as a result of the
     application of such rules, the "applicable dollar limit" is exceeded, then
     the limitation shall be prorated among the affected individuals in
     proportion to such individual's Compensation as determined under this
     Section 2.1(i) prior to the application of this limitation.

(j)  "CONTRIBUTIONS" under the Plan include--

A Participant shall either be an "Active Participant" or an "Inactive

Participant under the Plan, as provided for in Section 3.2, shall continue his

   15

(c)  If an Employee who incurs a One-Year Break in Service is subsequently
     reemployed by an Employer or non-participating Affiliate, the Years of
     Service the Employee had prior to such One-Year Break in Service shall be
     reinstated upon the Employee's reemployment; provided however, that if an
     Employee is reemployed after incurring five consecutive One-Year Breaks in
     Service, his service after reemployment shall be disregarded only for
     purposes of determining the vested portion of his pre-break Matching
     Contributions Account.

(d)  An Employee shall receive credit, for vesting and eligibility purposes, for
     any years of service credited for a period of employment by a corporation
     which is acquired, in whole or in part, by an Employer by merge or
     otherwise, but only if, and to the extent that, the Board of Directors (or
     the board of directors of any Employer that is a 100% owned subsidiary of
     the Company), specifically determines, at its discretion, to award credit
     for such service on a uniform and nondiscriminatory basis.

               released from military duty with the armed forces of the United
               States, in which case the Employee's Break in Service shall be
               deemed to have occurred on the first day of the Employee's
               authorized leave of absence for such military duty;

          (D)  is on an authorized leave of absence and fails to return to
               employment, in which case the Employee's Break in Service shall
               be deemed to have occurred on the first day of the Employee's
               authorized leave of absence; or 

          (E)  retires or dies.

               Hours of Service are being determined under the Plan.

          (B)  One hour for each hour, in addition to the hours in Section
               3.4(e)(4)(A), for which he is directly or indirectly paid, or
               entitled to payment, by an Employer or an Affiliate, on account
               of a period of time during which no duties are performed due to
               vacation, holiday, illness, disability, layoff, jury duty,
               military duty or Leave of Absence. Not more than 501 hours shall
               be credited under this Section 3.4(e)(4)(B) on account of any
               single continuous period during which he performs no duties. An
               hour is not required to be credited under this Section

               applicable worker's compensation, unemployment compensation or
               disability insurance laws, or if such payment is solely to
               reimburse an Employee for medical or medically related expenses
               incurred by the Employee.

          (C)  One hour for each hour for which back pay, irrespective of
               mitigation of damages, is either awarded or agreed to by an
               Employer or an Affiliate, with no duplication of credit for
               hours.

          (D)  Hours of Service shall be credited in accordance with the rules
               of Department of Labor regulation Section 2530.200b-2(b) and (c),
               which are incorporated herein by reference.

          (E)  For purposes of determining whether an Employee has had a
               One-Year Break in Service, an Employee who is absent from work
               for reasons of an "authorized maternity or paternity leave" shall
               be credited with the number of Hours of Service (not in excess of

   17

                    absence.

               an absence 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 such child by the Employee, or for purposes of caring
               for such child for a period immediately following such birth or
               placement. The Hours of Service described in this Section
               3.4(e)(4)(E)(i) shall be credited only in the Plan Year in which
               the absence from work begins if the Employee would be prevented
               from incurring a Break in Service in such Plan Year solely
               because of this provision or, in any other case, in the
               immediately following Plan Year.

3.5 SPECIAL PROVISIONS FOR PARTICIPANTS WHO ENTER THE ARMED FORCES

Participant's absence from employment as required by applicable law.

3.6 LEASED EMPLOYEES

A person who is not an Employee and who performs services for an Employer or an
Affiliate pursuant to an agreement between the Employer or Affiliate and a
leasing organization shall be considered a "leased employee" if such person
performed the services on a substantially full time basis for a period of at
least a year and the services are of a type historically performed by Employees
in the business field of the Employer or Affiliate. A person who is considered a
"leased employee" of an Employer or an Affiliate shall not be considered an
Employee for purposes of the Plan. If such a person becomes a Participant as a
result of subsequent employment with an Employer or nonparticipating Affiliate,
he shall receive service for his employment as a leased employee.
Notwithstanding the foregoing provisions of this Section 3.6, a leased employee
shall be included as an Employee for purposes of applying the requirements
described in Code section 414(n)(3) and for purposes of determining the number
and identity of Highly Compensated Employees.

percentage of After-Tax Contributions elected under this Section 4.3 for any
period shall not exceed 10 percent.

4.4 MATCHING CONTRIBUTIONS

(a)  MATCHING CONTRIBUTIONS PRIOR TO JULY 1, 1991. Prior to July 1, 1991, each
     Employer shall contribute an amount equal to 100 percent of the amount of
     Before-Tax Contributions and/or After-Tax Contributions contributed by or
     on behalf of each Active Participant employed by such Employer; provided,
     however, that no such Matching Contribution shall be made for any pay
     period which is in excess of 5 percent of the Active Participant's
     Compensation.

(b)  MATCHING CONTRIBUTIONS AFTER JUNE 30, 1991. After June 30, 1991, each
     Employer shall contribute an amount equal to 100 percent of the amount of
     Before-Tax Contributions contributed by or on behalf of each Active
     Participant employed by such Employer; provided, however, that no such
     Matching Contribution shall be made for any pay period which is in excess
     of 6 percent of the Active Participant's Compensation. Each Employer shall
     also contribute an amount equal to 100 percent of the amount of After-Tax
     Contributions contributed by or on behalf of each Active Participant
     employed by such Employer; provided, however, that no such Matching
     Contribution shall be made for any pay period which is in excess of 5
     percent of the Active Participant's Compensation. The 5 percent limitation
     in the preceding sentence shall be increased to 6 percent in the event an
     Active Participant elects to make After-Tax Contributions as a result of a
     suspension of his Before-Tax Contributions pursuant to the provisions of
     Section 4.6(a). Matching Contributions for any pay period with respect to
     both After-Tax Contributions and Before-Tax Contributions pursuant to this
     Section 4.4(b) shall not exceed an aggregate limit of 6 percent of an
     Active Participant's Compensation. 

(c)  IN GENERAL. The Matching Contributions to be made on behalf of an Active
     Participant for a Plan Year shall be determined by reference to each pay
     period within such Plan Year during which the Active Participant has an
     election in effect with respect to Before-Tax Contributions and/or
     After-Tax Contributions. Matching Contributions may be made in cash or in
     Company Stock, or in any combination of cash and Company Stock. The
     Matching Contributions made on behalf of an Active Participant shall be
     credited and allocated to his Matching Contributions Account.

4.5 ROLLOVER CONTRIBUTIONS

Effective September 1, 1992 an Eligible Employee may, in accordance with
procedures prescribed by the Committee, contribute the following amounts to the
Plan provided such amounts are delivered to the Trustee in cash or





                                       14
   20

cash equivalents:

(a)  All or any portion of a distribution (or proceeds from the sale of
     distributed property) which qualifies as an "eligible rollover
     distribution" as defined in Code section 402(c)(4), provided such amount is
     paid over to the Trustee on or before the 60th day after receipt by the
     Eligible Employee of the distribution, or such amount is a direct rollover
     to the Trustee made in accordance with Code section 401(a)(31) and the
     Treasury regulations thereunder. 

(b)  A distribution from an individual retirement account, the entire amount of
     which distribution is from a source described in Section 4.5(a).

All Rollover Contributions with respect to an Eligible Employee shall be
credited and allocated to such Eligible Employee's Rollover Contributions
Account.

4.6 LIMITATIONS ON CONTRIBUTIONS

In addition to the contribution limitations and requirements of Sections 4.2,
4.3 and 4.4, Contributions under the Plan shall be subject to the following
limitations and requirements:

(a)  LIMITATION ON BEFORE-TAX CONTRIBUTIONS. The maximum amount of Before-Tax
     Contributions contributed by an Employer on behalf of any Participant
     during a Plan Year shall be $7,627 (as adjusted by the Secretary of the
     Treasury to reflect increases in the cost of living). In any event where
     the Before-Tax Contributions limited by this Section 4.6(a) would exceed
     the maximum limitation provided herein, the election to make Before-Tax
     Contributions shall be suspended for the balance of that Plan Year and the
     Participant shall be entitled to elect to make After-Tax Contributions in
     lieu of the suspended Before-Tax Contributions as provided in Section
     4.6(b).

(b)  REDIRECTED CONTRIBUTIONS. In the event any Before-Tax Contributions are
     suspended pursuant to Section 4.6(a), the Participant shall be entitled to
     elect to make After-Tax Contributions in lieu of the suspended Before-Tax
     Contributions. Any After-Tax Contributions made pursuant to this Section
     4.6(b) shall not be subject to the percentage of pay limitation on
     After-Tax Contributions provided in Section 4.3 but shall be subject to the
     percentage of pay limitation on Before-Tax Contributions in Section 4.2.
     Any After-Tax Contributions made under this Section 4.6(b) in lieu of
     suspended Before-Tax Contributions shall be allocated to the Participant's
     After-Tax Contributions Account.



                                       15
   21

(c)  MAXIMUM DEDUCTIBLE CONTRIBUTIONS. In no event shall an Employer make
     Before-Tax Contributions and Matching Contributions on behalf of
     Participants for any Plan Year in an amount greater than the maximum
     amount which is deductible by such Employer under the applicable provisions
     of the Code. 

(d)  OTHER CONTRIBUTION LIMITATIONS. Contributions under this Article IV shall
     be further subject to the limitations and restrictions of Article VIII.

4.7 ELECTIONS RELATING TO CONTRIBUTIONS

Elections to make Before-Tax or After-Tax Contributions under the provisions of
this Article IV shall be subject to and governed by the following provisions of
this Section 4.7, in addition to the other conditions and requirements relating
to such Contributions as are contained in this Article IV: 

(a)  ELECTIONS IN GENERAL. All elections relating to Contributions by
     Participants shall be made on such form or forms and in such manner as may
     be prescribed by the Committee from time to time. Such election form shall
     be filed with the Committee, and shall designate the contribution rate or
     rates for the Contributions elected, provide for the appropriate payroll
     deduction and/or payroll reduction of the elected Contributions, specify
     the Investment Fund or Funds to which the Contributions are to be allocated
     pursuant to Section 9.3, and provide for such other information as the
     Committee may require from time to time. Elected Before-Tax Contributions
     and elected After-Tax Contributions shall be made by payroll reduction and
     deduction, respectively. Such Contributions shall be made with respect to
     each pay period the applicable election is in effect and shall be
     determined by multiplying the Active Participant's Compensation for such
     pay period by the elected contribution rate for the Before-Tax or After-Tax
     Contributions elected, with the product thereof rounded to the nearest
     whole cent. An Active Participant's election with respect to his Before-Tax
     or After-Tax Contributions shall remain in effect so long as he continues
     as an Active Participant, or until he makes a change with respect to such
     Contributions as provided in Section 4.7(c). 

(b)  COMMENCEMENT OF ELECTIONS. An Eligible Employee must file an election to
     make Before-Tax or After-Tax Contributions under the Plan in order to
     become an Active Participant. Such election to make Contributions shall
     become effective as of the Entry Date immediately following the date such
     election is filed or as soon thereafter as administratively practicable.




                                       16
   22

(c)  CHANGES IN CONTRIBUTION ELECTIONS. An Active Participant may elect to make
     a change with respect to his election of Before-Tax or After-Tax
     Contributions under the Plan on a semi-annual basis, including a change
     with respect to the type of such Contributions or the contribution rate or
     rates for such Contributions. An election with respect to Contributions
     under this Section 4.7(c) shall be filed with the Committee and shall be
     made on such form and in such manner as may be prescribed by the Committee
     from time to time. Such election change form shall be filed in advance of
     the semi-annual period to which it relates, as required by the Committee,
     and a timely filed election change shall then become effective as of the
     first day of such semi-annual period.

4.8 SUSPENSION OF CONTRIBUTIONS

An Active Participant may at any time elect to suspend all of his Before-Tax or
After-Tax Contributions under the Plan. An election to suspend Contributions
under this Section 4.8 shall be filed with the Committee and shall be made on
such form and in such manner as may be prescribed by the Committee from time to
time. An Active Participant's suspension election shall become effective as of
the first of the month immediately following the date on which his suspension
election is filed with the Committee, and such suspension election shall
thereafter continue in effect for six months. Before-Tax and After-Tax
Contributions will automatically resume after six months at the same rate or
rates as before the suspension, unless otherwise specified by the Participant.

4.9 PAYMENT OF CONTRIBUTIONS

The Employers shall deposit Contributions with the Trustee on at least a monthly
basis.

4.10 FORFEITURES

Any forfeitures arising under the terms of the Plan each Plan Year shall be used
to reduce the Employers' Matching Contributions for such Plan Year or any
following Plan Year. An Employer shall receive credit for the forfeitures (if
any) of the Members who were last employed by such Employer.

ARTICLE V. ACCOUNTS; ALLOCATION AND ADJUSTMENTS TO ACCOUNTS

5.1 ACCOUNTS OF MEMBERS

The Committee shall maintain, or cause to be maintained, an Account for each
Member for the purpose of accounting for the beneficial interest of each such
Member in the assets constituting the Trust Fund, which interest is attributable
to the Contributions credited to such Member under the Plan and as such interest
is adjusted from time to time to reflect Contributions, the earnings, gains and
losses on and changes in the value of the funds credited to the Account, charges
to reflect administrative expenses and any distributions or payments made to or
with respect to such Member from his Account. Each such Account shall consist of
the following subaccounts as may be applicable to the Member in order to account
for the specified Contributions to be credited to each such subaccount:

(a)  BEFORE-TAX CONTRIBUTIONS ACCOUNT-- to account for Before-Tax Contributions
     credited to the Account.

(b)  AFTER-TAX CONTRIBUTIONS ACCOUNT-- to account for After-Tax Contributions
     credited to the Account.

(c)  MATCHING CONTRIBUTIONS ACCOUNT-- to account for Matching Contributions
     credited to the Account.

(d)  ROLLOVER CONTRIBUTIONS ACCOUNT-- to account for Rollover Contributions
     credited to the Account. 

Each such subaccount, and any other subaccount maintained as part of a Member's
Account, shall reflect the applicable Contributions credited to the subaccount,
the earnings, gains and losses on and changes in the value of the funds credited
to the subaccount, charges to the subaccount to reflect administrative expenses
and any distributions or payment made to or with respect to the Member from the
subaccount. A Member's Account shall reflect the Member's investment interest of
the funds credited to such Account in the Investment Funds from time to time. In
the case of a loan pursuant to Section 7.6, the Member's Account shall reflect
the Member's investment interest of the funds credited to such Account in the
Member's loan. The Committee shall also maintain, cause to be maintained, such
other accounts, subaccounts, records or books as are deemed necessary to
properly provide for the maintenance of Accounts under the Plan, and to carry
the intent and purposes of the Plan.

5.2 ADJUSTMENT OF ACCOUNTS; VALUATION OF TRUST FUND

The Accounts of Members shall be adjusted to reflect all Contributions credited
to the Accounts, all payments, distributions and expenses charged to the
Accounts and all earnings, gains or losses on the funds credited to




                                       18
   24

the Accounts, with each such adjustment being made as soon as administratively
feasible following the event giving rise to the adjustment, but in any event at
least as frequently as of each Valuation Date. In making such adjustments, the
Member's Account shall reflect the allocations of the investment or reinvestment
of the funds credited to such Accounts among the Investment Funds (or loans
pursuant to Section 7.6), and the allocable shares of the Member's investment or
reinvestment therein. The assets of the Trust Fund shall be valued by the
Trustee as of each Valuation Date to reflect the value of the Trust assets on
such Date, and the change in such value from the immediately preceding Valuation
Date. Each valuation by the Trustee shall reflect the earnings, gains or losses
of the Trust Fund net of reasonable expenses, and the adjustment to a Member's
Account resulting from such valuation shall reflect such Account's pro rata
participation in the changes and values reflected thereby. The method of
valuation of the Trust Fund shall be determined by the Trustee pursuant to the
terms of the Trust Agreement and shall be followed with reasonable consistency
from Valuation Date to Valuation Date. Any such valuation shall be made on the
basis of the fair market value of the assets of the Trust Fund. All
determinations made by the Trustee as to fair market values, and all methods of
adjustment to allocations among Accounts, shall be made in accordance with
generally accepted accounting principles and pursuant to the terms of the Trust
Agreement.

5.3 ACCOUNT BALANCES

As of any relevant date, any Member's balance credited to his Account shall be
the value of the balance standing to the credit of his Account as of the
Valuation Date immediately preceding such relevant date, adjusted as necessary
to reflect any credits or charges made to such Account after such Valuation
Date, including, without limitation, those adjustments to reflect Contributions
to and payments from such Account.

5.4 ACCOUNT STATEMENTS

At least once each Plan Year, the Committee shall deliver to each Member in the
Plan a statement of the Member's Account under the Plan. The Committee may cause
such account statements to be distributed following each Valuation Date, or on
such other dates as the Committee may provide from time to time.

ARTICLE VI. VESTING IN ACCOUNTS

6.1  FULLY VESTED ACCOUNTS

A Member shall at all times be fully vested and have a nonforfeitable interest
in the balances credited to the Member's Before-Tax Contributions Account,
After-Tax Contributions Account and Rollover Contributions Account.

6.2  MATCHING CONTRIBUTIONS ACCOUNTS

(a)  Vesting in General. A Member shall have a vested and nonforfeitable
     interest in that vested percentage portion of the balance credited to his
     Matching Contributions Account at any time determined by reference to his
     completed Years of Service in accordance with the following schedule:



=============================================
YEARS OF SERVICE          VESTED PERCENTAGE

Less than 3 years         0%
3 years                   60%
4 years                   80%
5 or more years           100%
- ---------------------------------------------


(b)  Accelerated Vesting. Notwithstanding the provisions of Section 6.2(a), a
     Member shall be fully vested and have a nonforfeitable interest in the
     balance credited to his Matching Contributions Account if-

     (1)  he attains age 55 while an Employee;

     (2)  he dies or suffers a Disability while an Employee;

     (3)  he is credited with five Years of Service computed under Section 3.4,
          but disregarding the last clause of Section 3.4(b) thereby allowing
          such Member to be credited with a Year of Service for each Plan Year
          in which he has 1,000 or more Hours of Service irrespective of any
          election to make or not to make Before-Tax or After-Tax Contributions
          to the Plan; or

     (4)  while he is an Employee, contributions to the Plan are completely
          discontinued or the Plan is terminated, or the Plan is partially
          terminated and such Member is affected by such partial termination.

ARTICLE VII. DISTRIBUTIONS; LOANS; WITHDRAWALS

7.1  DISTRIBUTION UPON TERMINATION OF EMPLOYMENT

Upon termination of a Member's employment as an Employee for any reason, there
shall be distributed to the Member, or to his Beneficiary in the case of his
death, the vested portion of his Account determined as of the Valuation Date
coincident with or immediately preceding the date on which the distribution is
made (plus any nonforfeitable amounts credited to his Account subsequent to
such Valuation Date, if applicable).

7.2  COMMENCEMENT OF DISTRIBUTIONS

(a)  Subject to the provisions of this Section 7.2 and Section 7.4,
     distributions pursuant to Section 7.1 shall be made to the Member as soon
     as practicable following the Member's termination of employment as an
     Employee; provided, however, if the vested portion of a Member's Account
     exceeds $3,500 (or such higher amount as may be permitted under applicable
     law or regulation), then such distribution shall not be made (unless
     elected by the Member under Section 7.2(b)) at any time before the earlier
     of the Member's attaining age 70-1/2 or the Member's death.

(b)  Any Member who does not receive an immediate distribution following his
     termination of employment as an Employee as provided in Section 7.2(a)
     shall be entitled to elect to receive a distribution of the vested portion
     of this Account at any time prior to the time specified in Section 7.4.
     Such distribution shall be made as soon as practicable following the
     Member's notification to the Committee in accordance with procedures
     established by the Committee to effect such distributions.

(c)  If a Member dies after his termination of employment but prior to receiving
     the full distribution of his Account to which he is entitled under this
     Article VII, any unpaid balance thereof at the time of his death shall be
     distributed to the Member's Beneficiary in a lump sum, to be distributed as
     soon as practicable and permissible under the Code after his death.

7.3  METHOD OF DISTRIBUTION

All distributions shall be in a single lump sum payment. Such distribution
shall be made in cash; provided, however, that to the extent the Member's
Account is invested in Company Stock (or, prior to 1993, in government
bonds), the Member shall be entitled to elect a distribution in kind, subject




                                       21
   27

to minimum share limits as determined by the Committee from time to time.

7.4  REQUIRED DISTRIBUTIONS

Notwithstanding any of the preceding provisions of this Article VII-

(a)  In no event may the distribution of a Member's benefits commence later than
     April 1 of the calendar year following the year in which the Member
     reaches age 70-1/2; provided, however, that in the case of a Member who
     obtained age 70-1/2 prior to January 1, 1988, such distribution shall be
     required to be commenced prior to April 1 of the calendar year following
     the calendar year in which the Member retires.

(b)  A Member who remains in employment after reaching age 70-1/2 shall receive
     a distribution of his Account pursuant to subsection (a) and shall
     thereafter receive a distribution of his Account for each subsequent year
     that he remains employed.

(c)  If a Member dies prior to the commencement of the payments of benefits, the
     Member's benefits will be distributed as soon as practical following the
     Member's death.

(d)  All distributions under the Plan will be made in accordance with Code
     section 401(a)(9) and the regulations thereunder.

7.5  FORFEITURES

(a)  If a Member's employment as an Employee terminates and the value of the
     vested portion of the balance credited to his Account is not greater than
     $3,500 (or such higher amount as may be permitted by applicable law or
     regulation), the Member shall receive a distribution of the value of the
     vested portion of his Account and the value of the nonvested portion shall
     be treated as a forfeiture and applied in accordance with Section 4.10.

(b)  If a Member's employment as an Employee terminates and the value of the
     vested portion of the balance credited to his Account is greater than
     $3,500 (or such higher amount as may be permitted by applicable law or
     regulation), the Member may elect to receive a distribution of the value of
     the vested portion of his Account and the value of the nonvested portion of
     such Accounts shall be treated as a forfeiture and applied in accordance
     with Section 4.10.

(c)  If a Member receives a distribution pursuant to Section 7.5(a) or (b) which
     is less than the full value of the Member's Account and he is reemployed by
     an Employer or Affiliate prior to incurring five consecutive One-Year
     Breaks in Service, any portion of such Account




                                       22
   28

     forfeited pursuant to Section 7.5(a) or (b) shall be restored if the Member
     repays to the Plan the full amount of his distribution. Such repayment must
     be made prior to the fifth anniversary of the first date on which the
     Member is subsequently reemployed as an Employee. The source for restoring
     forfeitures shall be first, current forfeitures, and if insufficient, an
     additional contribution by the Member's Employer. Repaid distributions and
     restored forfeitures shall be allocated to the Member's After-Tax
     Contributions Account and shall be invested in an Investment Fund or Funds
     as designated by the Member.

(d)  If a Member incurs five consecutive One-Year Breaks in Service or if
     Section 7.5(c) is applicable to the Member but he fails to make the
     repayment described therein, the prior forfeiture shall not be reinstated,
     or if no amount was forfeited at such time, the nonvested portion of his
     Account shall no longer be eligible for reinstatement at the time he incurs
     five consecutive One-Year Breaks in Service.

7.6  LOANS

An "eligible Member" may make a loan from the "Loan Assets" credited to his
Account in accordance with the provisions of this Section 7.6 and any loan
procedures established from time to time by the Committee. Any such loan shall
be subject to the following provisions of this Section 7.6: 

(a)  LOANS IN GENERAL. Loans under this Section 7.6 shall only be available to
     an "eligible Member" as described in Section 7.6(b). Each request for a
     loan shall be filed with the Committee on such form and in such manner as
     may be prescribed by the Committee from time to time, and shall be
     accompanied by such other documents as the Committee may require for
     processing the loan request. Subject to the further provisions of this
     Section 7.6, the Committee may from time to time adopt such rules relating
     to the terms, conditions and the making of loans as it deems appropriate,
     including, without limitation, rules limiting the number and frequency of
     the loans that may be made by an eligible Member, providing for a minimum
     loan amount, providing for a fee for a loan, and governing the loan
     repayment procedures.

(b)  ELIGIBLE MEMBERS. The term "eligible Member" shall mean a Member who is an
     Employee on the date the loan is made or any other Member who is a "party
     in interest" as defined in ERISA Section 3(14) on the date on which the
     loan is made. A loan to an eligible Member who is not an Employee may be
     offered on different terms and conditions than other loans where the
     differences are based solely on factors that are legally considered by
     commercial entities in the business of making similar loans. Pursuant to
     the Committee's written





                                       23
   29

     administrative rules, regulations and procedures (as provided for in
     Section 7.6(a)), the Committee shall determine the terms and conditions for
     such loans which may include, but shall not be limited to, charging an
     application fee, charging a higher interest rate, requiring a credit report
     and providing a payment method and schedule for loan repayments.

(c)  LOAN ASSETS. All or any portion of the balance credited to the eligible
     Member's Before-Tax Contributions Account or Rollover Contributions Account
     (except to the extent invested in Company Stock or PSA Stock) shall be
     "Loan Assets" available for loans pursuant to this Section 7.6. The value
     of the eligible Member's Loan Assets shall be determined as of the
     Valuation Date coincident with or immediately preceding the date on which
     his loan request form is filed with the Committee. The Committee shall
     adopt rules and procedures for the allocation of loan payments among the
     Investment Funds in which the eligible Member's Loan Assets are invested.

(d)  AMOUNT OF LOAN. The maximum amount of an eligible Member's loan or loans
     under this Section 7.6 shall not exceed the lesser of:

     (1)  $50,000, reduced by the excess (if any) of--

          (A)  the highest outstanding balance of the loan of such Member under
               the Plan during the one-year period ending on the date before the
               date on which a loan is made, over

          (B)  the outstanding balance of the loan of such Member under the Plan
               on the date on which such loan is made, or

     (2)  One-half of the current value of such Member's vested interest in his
          Before-Tax Contributions Account, Matching Contributions Account and
          Rollover Contributions Account.

     All determinations of the maximum loan amount under this Section 7.6(d)
     shall be made as of the date any loan payment is to be made, and such
     maximum amount shall reflect any outstanding loans the eligible Member may
     have under any other qualified plan maintained by the Employers or any
     Affiliate. The minimum amount of any loan shall be $1,000.

(e)  TERM OF LOAN. The term for the repayment of any loan under this Section 7.6
     shall not extend beyond a five-year period from the date of the loan
     payment; provided, however, that, if such loan is to be used to acquire a
     dwelling unit which within a reasonable period of time is to be used as the
     principal residence of the eligible Member, then the term for such loan may
     extend beyond such five-year period and for a period as approved by the
     Committee.

(f)  INTEREST RATE. All loans under this Section 7.6 shall bear a reasonable
     rate of interest which provides the Plan with a return commensurate





                                       24
   30

     with the prevailing interest rate charged on similar commercial loans by
     persons in the business of lending money. Such interest rate shall be
     determined by the Committee in accordance with its rules and procedures,
     and after giving due consideration to those factors as may be prescribed
     under Section 408(b)(6) of ERISA or other applicable law with respect to
     establishing interest rates for loans under employee benefit plans.

(g)  EVIDENCE OF LOAN. No loan shall be made to any eligible Member prior to the
     execution and submission by him of--


     (1)  a written application therefor;

     (2)  a promissory note payable to the Trustee in an amount and on a form
          prescribed by the Committee; and

     (3)  a written authorization for loan repayment by means of payroll
          deductions, except where a different repayment method is provided for
          an eligible Member who is not an Employee.

(h)  LOAN REPAYMENTS. All loan repayments of principal and interest shall be
     made in substantially equal amounts (with such payments no less frequently
     than on a quarterly basis) so as to permit the loan to be amortized over
     the term of the loan. Except as otherwise provided by the Committee, loan
     repayments shall be by payroll deductions. Repayments of principal and
     interest received on each loan shall be credited to the eligible Member's
     applicable Account from which Loan Assets were paid and shall be allocated
     for reinvestment on the basis of the Member's investment election in effect
     at the time of such repayment. An eligible Member shall be entitled to make
     a prepayment in cash, without penalty, for the total outstanding principal
     amount of and interest accrued on a loan.

(i)  LAYOFF OR LEAVE OF ABSENCE. An eligible Member with an outstanding loan who
     is on Leave of Absence for any reason shall be entitled to continue loan
     repayments in installment payments equivalent in value to the payments then
     being deducted by payroll deduction.

(j)  TERMINATION OF EMPLOYMENT. All outstanding loans shall be due and payable
     as of the date of an eligible Member's termination of employment as an
     Employee for any reason. An eligible Member who, prior to his repayment of
     the total principal amount and accrued interest of a loan, terminates
     employment as an Employee for any reason, shall have his loan promissory
     note cancelled and treated as distributed to him, unless such eligible
     Member elects to repay the outstanding balance of the loan in full. In the
     event that an eligible Member who is not an Employee terminates his status
     as "party in interest" (as described in Section 7.6(b)) before the
     repayment of a loan under this Section 7.6, the unpaid balance on the loan,
     together with




                                       25
   31

     the accrued interest, shall immediately become due and payable.

(k)  LOAN DEFAULT. In the event an eligible Member defaults on a loan, the
     entire outstanding balance of and accrued interest on the loan shall be due
     and payable. The amount of such loan default shall be charged against such
     eligible Member's Account in accordance with rules and procedures
     prescribed by the Committee from time to time. Such charges against the
     eligible Member's Account shall be treated as a distribution with respect
     to such Member; provided, however, that such a charge against an eligible
     Member's Account shall not occur with respect to funds in his Before-Tax
     Contributions Account at a time so as to cause a violation of the
     provisions of Code section 401(k)(2)(B)(i).

(1)  SECURITY FOR LOAN. The outstanding principal balance of and accrued
     interest on any loan by an eligible Member shall be secured by 50 percent
     of the balances credited to his Before-Tax Contributions Account and
     Rollover Contributions Account (which shall include such outstanding loan
     balance). Where it deems necessary, the Committee may also require the
     eligible Member to provide additional security for the repayment of any
     loan. No loan shall be made or remain outstanding unless the loan amount
     (or the outstanding balance thereof) is adequately secured.

(m)  RESTRICTION ON LOANS. Notwithstanding the foregoing provisions of this
     Section 7.6, the Committee may limit loans, deny loans, declare moratoriums
     on the granting of loans to eligible Members, and make the necessary rules
     and regulations to implement this Section 7.6.

7.7  IN-SERVICE WITHDRAWALS

A Member may make a withdrawal from his Account in accordance with the following
provisions:

(a)  AGE 59-1/2. A Member may make a withdrawal of all or any portion of the
     vested amounts credited to his Account at any time after he attains age
     59-1/2.

(b)  BEFORE AGE 59-1/2. Prior to attaining age 59-1/2, a Member may make a
     withdrawal of all or any portion of (i) the amount credited to his
     After-Tax Contributions Account, or (ii) the vested amount credited to his
     Matching Contributions Account prior to 1984. A Member may make only two
     such withdrawals pursuant to this Section 7.7(b) during a Plan Year and no
     more than five such withdrawals during a five year period.

(c)  WITHDRAWALS IN GENERAL. All withdrawal requests pursuant to this Section
     7.7 shall be filed with the Committee, and shall be made on such withdrawal
     request form and in such manner as the Committee





                                       26
   32

     may prescribe from time to time. In addition, withdrawals and withdrawal
     payments pursuant to this Section 7.7 shall be subject to and made
     in accordance with such rules and procedures as the Committee may prescribe
     from time to time, including rules governing the withdrawal and allocation
     of withdrawal payments among the Investment Funds in which the Member's
     Account is invested. The value of the Member's funds available for
     withdrawal shall be determined as of the Valuation Date coincident with or
     immediately preceding the date on which his withdrawal request form is
     filed with the Committee. The minimum amount of any withdrawal shall be
     $500.

7.8  WITHHOLDING TAXES

The Employer may withhold from a Member's Compensation and the Trustee may
withhold from any payment under this Plan any taxes required to be withheld
with respect to contributions or benefits under this Plan.

     any portion of an "Eligible Rollover Distribution" paid directly to an
     "Eligible Retirement Plan" specified by the "Distributee" in a "Direct
     Rollover" to the extent permitted by Code section 401(a)(31). Terms in
     quotation marks are defined in Section 7.9(b) below.

          Participant's retirement benefit: 

          (A)  The Participant;

          (B)  The Participant's surviving spouse; and

          (C)  An alternate payee under a qualified domestic relations order, as
               defined in Code section 414(p), if that person is the spouse or
               former spouse of the Participant.

          section 403(a), or a qualified trust described in Code section 401(a),
          that accepts the Distributee's Eligible Rollover Distribution.
          However, in the case of an Eligible





                                       27
   33

          Rollover Distribution to a Distributee's surviving spouse, an
          "Eligible Retirement Plan" is an individual retirement account or
          individual retirement annuity, as such terms are defined in the
          preceding sentence.

     (4)  "ELIGIBLE ROLLOVER DISTRIBUTION" means any distribution of all or any
          portion of the retirement benefit payable to the Distributee, except
          that an "Eligible Rollover Distribution" does not include:

          (A)  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 expectancy) of the Distributee or the
               Distributee's designated beneficiary, or for a specified period
               of ten years or more;

          (B)  Any distribution to the extent such distribution is required
               under Code section 401(a)(9);

          (C)  The portion of any distribution that is not includible in gross
               income (determined without regard to the exclusion for net
               unrealized appreciation with respect to employer securities); and

          (D)  Any other amounts which are not considered "Eligible Rollover
               Distributions" under Code section 401(a)(31).

(c)  No amount shall be directly rolled over pursuant to this Section 7.9 unless
     and until it would otherwise be distributed to the Distributee and all
     consents and written elections required to make the distribution have been
     obtained.

(d)  The Committee shall provide notice to each Distributee who will receive an
     Eligible Rollover Distribution of the Distributee's right to elect a Direct
     Rollover in accordance with Code section 401(a)(31). The Committee shall
     provide such notice at the time and in the manner required by regulations.

(e)  The Distributee shall notify the Committee in writing by such deadline as
     the Committee shall prescribe whether or not he wishes to have any part of
     the Eligible Rollover Distribution directly rolled over. If the Distributee
     fails to elect a Direct Rollover by the deadline established by the
     Committee, then the entire amount of the Eligible Rollover Distribution
     shall be distributed directly to the Distributee.

(f)  A Distributee may elect that the lowest of the following amounts shall be
     directly rolled over:

     (1)  The entire amount of the Eligible Rollover Distribution;

     (2)  Such portion of the Eligible Rollover Distribution as the Distributee
          specifies (in accordance with rules established by the Committee),
          provided that the amount directly rolled over is not




                                       28
   34

          less than $500 or such higher amount as the Committee may prescribe in
          accordance with Treasury regulations; or

     (3)  No portion of the Eligible Rollover Distribution if his Eligible
          Rollover Distribution is less than $200.

(g)  The Distributee may only request a Direct Rollover to one Eligible
     Retirement Plan.

(h)  No amount will be directly rolled over pursuant to this Section 7.9 unless
     the Distributee provides the Committee, by such deadline as the Committee
     shall prescribe, such information as it shall require:

     (1)  To determine that the amount directly rolled over will be received by
          an Eligible Retirement Plan that will accept the Direct Rollover; and

     (2)  To make the Direct Rollover and make such reports and keep such
          records as are required under applicable law. 

     The Committee may rely on all such information provided by the Distributee
     and shall not be required to verify any such information.

(i)  The Committee shall select the manner in which to make the Direct Rollover.

(j)  Any amount directly rolled over in accordance with this Section 7.9 shall
     be a distribution from this Plan and shall discharge any liability to the
     Distributee under this Plan to the same extent as a payment directly to the
     Distributee.

ARTICLE VIII. LIMITATIONS

8.1  LIMITATIONS ON BEFORE-TAX CONTRIBUTIONS

(a)  IN GENERAL. In no event shall any Employer make Before-Tax Contributions
     for any Plan Year that would result in the actual deferral percentage of
     the group of Highly-Compensated Employees who are Eligible Employees and
     are participating or are eligible to participate as Participants exceeding
     the actual deferral percentage of the group of all other of such Eligible
     Employees by more than the greater of--

     (1)  one and one-quarter times, or

     (2)  the lesser of (A) two times or (B) two percentage points.

     The deferral percentage of each group of such Eligible Employees for any
     Plan Year shall be the average of the ratios (calculated separately for
     each Eligible Employee in each such group) of (i) the Before-Tax
     Contributions made on behalf of such Eligible Employee for such Plan Year
     to (ii) such Eligible Employee's Compensation for such Plan Year.

(b)  SPECIAL RULES. For purposes of this Section 8.1, the actual deferral
     percentage for any Eligible Employee who is a Highly-Compensated Employee
     for the Plan Year and who is eligible to have Before-Tax Contributions
     allocated to his accounts under two or more plans or arrangements
     maintained by the Employer or an Affiliate (excluding plans that cannot be
     permissively aggregated) shall be determined as if all such Before-Tax
     Contributions were made under a single arrangement.

     For purposes of this Section 8.1, any Before-Tax Contributions made under
     two or more plans maintained by the Employer or an Affiliate which are
     aggregated for purposes of Code sections 401(a)(4) or 410(b) (other than
     Code section 410(b)(2)(A)(ii)) are to be treated as made under a single
     plan. And if two more plans are permissively aggregated for purposes of
     applying the average deferral percentage test then the aggregated plans
     must satisfy Code sections 401(a)(4) and 410(b) as though they were a
     single plan.

     If an Eligible Employee is a member of the family of a five percent owner
     or one of the ten most Highly-Compensated Employees, such Eligible
     Employee shall not be treated as a separate Employee and his Compensation
     and his Before-Tax Contributions shall be treated as attributable to a
     single five percent owner or Highly-Compensated Employee. For such a
     family group (which is treated as a single Highly-Compensated Employee),
     the actual deferral percentage for each individual shall be determined by
     combining the Compensation and Before-Tax Contributions of all such family
     members. If the




                                       30
   36

     Before-Tax Contributions of an aggregated Highly-Compensated Employee have
     to be reduced to conform to the limitations in Section 8.1(a), the
     Before-Tax Contributions of each family member shall be reduced in
     proportion to the amount of Before-Tax Contributions made by each family
     member.

     Any Eligible Employee covered by a collective bargaining agreement that
     provides for his participation in the Plan shall not be included when the
     limits of this Section 8.1 are applied to Eligible Employees who are not
     covered by a collective bargaining agreement, and the limits of this
     Section 8.1 shall be separately applied to each group of Eligible
     Employees covered by a separate collective bargaining agreement.

     The determination and treatment of the Before-Tax Contributions and actual
     deferral percentage of any Eligible Employee shall satisfy such other
     requirements as prescribed by the Secretary of Treasury.

(c)  CORRECTION METHODS.

     (1)  DISTRIBUTION. To the extent necessary to conform to the limitations in
          Section 8.1(a), the Committee shall reduce the Before-Tax
          Contributions made on behalf of the Highly Compensated Employees. Such
          reduction shall be effected by reducing Before-Tax Contributions made
          on behalf of Highly Compensated Employees (in the order of their
          actual deferral percentages) beginning with the Highly-Compensated
          Employees who elected the highest percentage of such Contributions, in
          accordance with the "leveling" method described in Treas.
          Reg.1.401(k)-1(f)(2). A reduction pursuant to this Section 8.1(c)(2)
          which results in a refund of Before-Tax Contributions already
          contributed under the Plan shall include with such refunded amounts
          any earnings allocable to such refunded amount through the end of the
          Plan Year. Any such refunded earnings shall be computed in accordance
          with a method established by the Committee that is used consistently
          for all Participants and for all refunded amounts for the Plan Year,
          and is used by the Plan for allocating income to Participants'
          Accounts. The Matching Contributions, if any, that relate to such
          distributed Before-Tax Contributions shall be treated as a forfeiture
          under Section 4.10 except to the extent that such amounts are
          distributable pursuant to Section 8.2(c). The amount of Before-Tax
          Contributions refunded to a Participant pursuant to this Section
          8.1(c)(1) shall be reduced by the amount of any Before-Tax
          Contributions previously distributed to the Participant to comply with
          the limitations of Section 8.4.



                                       31
   37
     (2)  ADDITIONAL ACTIONS. The Committee may take such additional action as
          it shall consider appropriate to ensure compliance with the
          requirements of Section 8.1. Such action may include the
          implementation of limits on Before-Tax Contributions contributed by or
          on behalf of Highly-Compensated Employees at periodical intervals
          through a Plan Year that the Committee deems necessary or appropriate
          to assure compliance at year end. Such rules may provide each Active
          Participant affected by such limitation an opportunity to make a
          change with respect to his Before-Tax Contributions election at the
          time a reduction is applied, and at such later time when such
          reductions are no longer necessary to comply with the limitations of
          Section 8.1.

8.2  LIMITATIONS ON AFTER-TAX CONTRIBUTIONS AND MATCHING CONTRIBUTIONS

(a)  IN GENERAL. In no event shall After-Tax Contributions and Matching
     Contributions for any Plan Year be made which would result in the
     contribution percentage of the group of Highly-Compensated Employees who
     are Eligible Employees and are participating or are eligible to participate
     as Participants exceeding the contribution percentage of the group of all
     other of such Eligible Employees by more than the greater of--

     (1)  one and one-quarter times, or

     (2)  the lesser of (A) two times or (B) two percentage points.

     The contribution percentage of each group of such Eligible Employees for
     any Plan Year shall be the average of the ratios (calculated separately for
     each Eligible Employee in each such group) if (i) the After-Tax
     Contributions and the Matching Contributions made on behalf of each such
     Eligible Employee for such Plan Year to (ii) such Eligible Employee's
     Compensation for such Plan Year.

(b)  SPECIAL RULES. For purposes of this Section 8.2, the contribution
     percentage for any Eligible Employee who is a Highly-Compensated Employee
     for the Plan Year and who is eligible to have Matching Contributions and/or
     After-Tax Contributions allocated to his accounts under two or more
     arrangements maintained by the Employer or an Affiliate (excluding plans
     that cannot be permissively aggregated) shall be determined as if all such
     contributions were made under a single arrangement.

     For purposes of this Section 8.2, any After-Tax or Matching Contributions
     made under two or more plans maintained by the Employer or an Affiliate
     which are aggregated for purposes of Code sections 401(a)(4) or 410(b)
     (other than Code section 410(b)(2)(A)(ii)) are to be treated as made under
     a single plan. And if two or more





                                       32
   38

          plans are permissively aggregated for purposes of applying the
          contribution percentage test then the aggregated plans must satisfy
          Code sections 401(a)(4) and 410(b) as though they were a single plan.
          If an Eligible Employee is a member of the family of a five percent
          owner or one of the ten most Highly-Compensated Employees, such
          Eligible Employee shall not be treated as a separate Employee and his
          Compensation under After-Tax and Matching Contributions shall be
          treated as attributable to a single five percent owner or Highly-
          Compensated Employee. For such a family group (which is treated as a
          single Highly-Compensated Employee), the actual deferral percentage
          for each individual shall be determined by combining the Compensation
          and After-Tax and Matching Contributions of an aggregated
          Highly-Compensated Employee have to be reduced to conform to the
          limitations of Section 8.2(a), the After-Tax and Matching
          Contributions of each family member shall be reduced in proportion
          into the amount of After-Tax and Matching Contributions made by each
          family member. 

          Any Eligible Employee covered by a collective bargaining agreement
          that provides for his participation in the Plan shall not be included
          when the limits of this Section 8.2 are applied to Eligible Employees
          who are not covered by a collective bargaining agreement. Matching
          Contributions and After-Tax Contributions made on behalf of Highly-
          Compensated Employees who are covered by a collective bargaining
          agreement shall not be subject to the limits of this Section 8.2. The
          determination and treatment of the After-Tax Contributions, Matching
          Contributions and contribution percentage of any Eligible Employee
          shall satisfy such other requirements as prescribed by the Secretary
          of the Treasury.

     (c)  CORRECTION METHODS.

          (1)  DISTRIBUTION. To the extent necessary to conform to the
               limitations in Section 8.2(a), the Committee shall reduce the
               After-Tax Contributions and the Matching Contributions made on
               behalf of the Highly-Compensated Employees. Such reductions
               shall be affected by reducing After-Tax Contributions and
               Matching Contributions made by or on behalf of Highly-Compensated
               Employees (in order of their actual contribution percentages)
               beginning with the Highly-Compensated Employee who elected the
               highest percentage of such contributions, in accordance with the
               "leveling" method described in Treas. Reg.1.401(m)-l(e)(2)(i).
               Any such reduction with respect to After-Tax Contributions
               already contributed under the Plan on behalf of any Participant
               shall refunded to the Participant. Any such





                                       33
   39

          reductions with respect to the Matching Contributions already made
          under the Plan on behalf of any Participant shall be paid to the
          Participant (to the extent he is vested) or treated as a forfeiture
          (to the extent forfeitable). Such refunds or payment shall be made as
          soon as administratively feasible, but will be made at the latest
          before the close of the following Plan Year. The reductions provided
          for under this Section 8.2(c) shall also be made in accordance with
          such rules as the Committee may provide from time to time, including
          rules similar to the rules described in Section 8.1(c) relating to
          changes with respect to Before-Tax Contributions elections. A
          reduction pursuant to this Section 8.2(c) which results in a refund or
          payment of After-Tax Contributions or Matching Contributions already
          contributed under the Plan shall include with such refunded amounts
          any earnings allocable to such refunded amounts through the end of the
          Plan Year. Any such refunded earnings shall be computed in accordance
          with a method established by the Committee that is used consistently
          for the Plan Year, and is used by the Plan for allocating income to
          Participants' Accounts.

     (2)  ADDITIONAL ACTIONS. The Committee may take such additional action as
          it shall consider appropriate to ensure compliance with the
          requirements of this Section 8.2.

8.3  COMBINATION OF LIMITATIONS; MULTIPLE USE

(a)  The Committee may comply with the limitations of Sections 8.1 and 8.2 by
     combining contributions under the Plan with contributions under any other
     defined contribution plan maintained by an Employer or an Affiliate. Such
     combination shall be done in compliance with applicable final Treasury
     regulations. To the extent permitted by Treas. Reg.1.401(m)-l(b)(5), the
     Committee may also elect to take Before-Tax Contributions into account in
     applying the contribution percentage test under Section 8.2(a).

(b)  The deferral and contribution percentage test limitations of Sections
     8.1(a) and 8.2(a) shall be applied in accordance with the provisions of
     Code sections 401(k) and 401(m), and in accordance with the provisions of
     Treas. Reg.1.401(m)-2 governing alternative limitations. If the multiple
     use of alternative limitations occurs, and correction becomes necessary,
     such correction shall be made in accordance with the provisions of Treas.
     Reg.1.401(m)-2(c) by reducing the actual contribution percentage of all
     Highly-Compensated Employees.





                                       34
   40

8.4  LIMITATIONS ON ANNUAL ACCOUNT ADDITIONS

(a)  ANNUAL ACCOUNT ADDITION. "Annual Account Addition" means for any
     Participant for any Plan Year, which shall also be the limitation year, the
     sum of-

     (1)  Employer or employee contributions made for him under any defined
          contribution plan, including excess contributions (as defined in Code
          section 401(k)(8)(B)), excess aggregate contributions (as defined in
          Code section 401(m)(6)(B)) and excess deferrals (as described in Code
          section 402(g)), irrespective of whether such amounts are distributed
          or forfeited;

     (2)  Forfeitures allocated to him under any defined contribution plan; and

     (3)  Amounts described in Code sections 415(l)(1) and 419A(d)(2) allocated
          to him.

     "Any defined contribution plan" means all defined contribution plans of the
     Employers and Affiliates considered as one plan. For purposes of this
     Section 8.4, "Affiliate" shall have the meaning provided in Section 2.1(b),
     except that the phrase "more than 50%" shall be substituted for the phrase
     "at least 80%" each place it appears in Code section 1563(a)(1). Repaid
     distributions and restored forfeitures pursuant to Section 7.5 or a
     Rollover Contribution pursuant to Section 4.5 shall not be included as part
     of a Participant's Annual Account Addition (nor shall any similar amounts
     under any other defined contribution plan).

(b)  LIMITATION. A Participant's Annual Account Addition for any Plan Year shall
     not exceed the lesser of-

     (1)  $30,000, or if greater, one-fourth of the defined benefit dollar
          limitation set forth in Code section 415(b)(1)(A) as in effect for the
          limitation year; or

     (2)  25 percent of the Participant's Compensation.

     The limitation in Section 8.4(b)(2) shall not apply to (i) any contribution
     for medical benefits (within the meaning of Code section 419A(f)(2)) after
     separation from service which are treated as an Annual Account Addition, or
     (ii) any amount otherwise treated as an Annual Account Addition under Code
     section 415(l)(1).

(c)  ADDITIONAL LIMITATION. If in any Plan Year a Participant is covered both
     under any defined contribution plan and under any defined benefit plan, the
     sum of the defined benefit plan fraction (as defined in Code section
     415(e)(2)) and the defined contribution plan fraction (as defined in Code
     section 415(e)(3)) for such Plan Year shall not exceed one. In calculating
     the defined contribution fraction, the Committee may make the election
     described in Code section 415(e)(6). It is




                                       35
   41

     intended to reduce the benefits payable under any defined benefit plan to
     the extent necessary to prevent the sum of such fractions for any Plan Year
     from exceeding one before reducing contributions to any defined
     contribution plan. "Any defined benefit plan" means all defined benefit
     plans of the Employers and Affiliates considered as one plan.

(d)  REDUCTION IN ANNUAL ACCOUNT ADDITIONS. If in any Plan Year a Participant's
     Annual Account Addition exceeds the limitation determined under Section
     8.4(b), such excess shall not be allocated to his accounts in any defined
     contribution plan but shall be handled in the following manner and order
     until such excess is eliminated:

     (1)  His after-tax contributions or any part thereof shall be refunded to
          him;

     (2)  His portion of the before-tax contributions or any part thereof made
          on his behalf shall be refunded to him;

     (3)  His portion of the allocation of employer matching contributions or
          any part thereof shall be placed in a suspense account, and

     (4)  His portion of the allocation of any employer contributions (other
          than employer contributions described in Section 8.4(d)(2) and (d)(3))
          or any portion thereof shall be placed in a suspense account.

     Such reductions shall be applied first to any other defined contribution
     plan, and thereafter to the Plan. The amount held in any suspense account
     that is attributable to Matching Employer Contributions of an Employer
     shall be used to reduce such Contributions by that Employer for the next
     following Plan Year. Such suspense account shall not share in the gains and
     losses of the Trust Fund.

(e)  CODE SECTION 415. The limitations and provisions of this Section 8.4 shall
     be applied in accordance with the provisions of Code section 415 and the
     regulations issued thereunder, which are hereby incorporated by reference
     into the Plan. In addition, the limitations and reductions provided for in
     this Section 8.4 shall be applied in accordance with such rules as the
     Committee may prescribe from time to time to carry out the provisions of
     this Section 8.4 and Code section 415.

9.1  INVESTMENTS

(a)  INVESTMENTS IN GENERAL. All Contributions shall be paid over to the Trustee
     and shall be invested promptly by the Trustee as provided in this Article
     IX and in accordance with the terms of the Trust Agreement. Dividends,
     interest, earnings, proceeds from the sale or tender of assets or
     securities (except where a loan, withdrawal, or distribution is being made)
     and other income from the assets credited to an Investment Fund shall be
     promptly reinvested in such Fund.

(b)  BEFORE-TAX AND AFTER-TAX CONTRIBUTIONS. Before-Tax and After-Tax
     Contributions and all other funds credited to a Member's Before-Tax
     Contributions Account, After-Tax Contributions Account and Rollover
     Contributions Account under the Plan shall be invested in the Investment
     Funds in accordance with the Member's investment elections in effect from
     time to time and the provisions of this Article IX.

(c)  INVESTMENT OF MATCHING CONTRIBUTIONS ACCOUNT. Matching Contributions and
     all other funds credited to a Member's Matching Contributions Account under

     authorized and directed by the Committee.

(d)  LOANS. Notwithstanding the foregoing provisions of this Section 9.1, in any
     case where a Member has made a loan of any portion of his Account pursuant
     to the Section 7.6, the Member shall be deemed to have directed the
     investment of the outstanding balance of such loan from time to time, and
     such balance shall be invested in such loan in accordance with the terms of
     the loan and the provisions of Section 7.6.

9.2  INVESTMENT FUNDS

   43

for the investment of the funds credited to the Members' Accounts (other than
the Matching Contributions Account which shall remain invested solely in
Company Stock and/or PSA Stock). The Committee shall instruct and advise the
Trustee and the Members as to the addition or deletion of an Investment Fund,
including the effective date of any such addition or deletion and any special
provisions as may be applicable to the investment elections or transfers with
respect to the Investment Funds. The Committee shall designate the investment
company, insurance company or other financial institution or institutions
(including the Trustee) responsible for the management and administration of
the investment of the funds of each Investment Fund. The Committee shall also
establish such investment guidelines or directions as it may deem appropriate
relating to the investment management and administration of Investment Fund.
The investment of funds in the Investment Fund shall also be subject to the
investment provisions of the Trust Agreement.

9.3  INVESTMENT ELECTIONS FOR CONTRIBUTIONS

Each Participant shall file with the Committee an investment election with
respect to the Contributions made by or on behalf of such Participant under the
Plan. Such investment election shall be made on such form or forms and in such
manner as the Committee shall prescribe from time to time. The Participant's
investment elections shall be filed at the following times and subject to the
following provisions: 

(a)  COMMENCEMENT OF ACTIVE PARTICIPATION. Whenever a Participant commences or
     recommences active participation under the Plan as provided in Section 3.2
     or 3.3, such Participant shall file his investment election form no later
     than the date on which he is to commence or recommence his status as an
     Active Participant. Such investment election shall be applicable to all
     subsequent Contributions (other than Rollover Contributions) made on behalf
     of such Participant under the Plan and the investment election shall remain
     in effect so long as the Participant continues as an Active Participant, or
     until such Participant makes a change with respect to the investment of his
     future Contributions, as provided in Section 9.3(c).

(b)  ROLLOVER CONTRIBUTIONS. Whenever a Participant (including an Inactive
     Participant) makes a Rollover Contribution (as provided in Section 4.5),
     such Participant shall file his investment election form no later than the
     date on which his Rollover Contribution is made to the Plan. Such
     investment election shall be applicable with respect to the Rollover
     Contribution made by or on behalf of the Participant.

(c)  CHANGE IN INVESTMENT ELECTION. A Participant may file an investment change
     election form as prescribed by the Committee to be effective




                                       38
   44

     with respect to all future Contributions (other than Rollover
     Contributions) made by or on behalf of such Participant under the Plan
     from and after the date on which such investment change becomes effective.
     Any such investment changes shall become effective at periodic intervals
     during the Plan Year (e.g., quarterly) as determined by the Committee and
     communicated to Participants. Participant investment elections shall remain
     in effect so long as the Participant continues as an Active Participant, or
     until the Participant makes a change with respect to the investment of his
     future Contributions, as provided in this Section 9.3(c).

(d)  ELECTRONIC OR TELEPHONIC CHANGES. From time to time, the Committee may
     authorize alternative methods for effecting changes in investment
     elections, including electronic or telephonic communications, with respect
     to some or all Contributions made by or on behalf of an Active Participant
     with respect to pay periods subsequent to such electronic or telephonic
     communication. Any such authorized change in investment election shall be
     in lieu of the written form prescribed in Section 9.3(c) and shall be
     considered "filed" for purposes of this Article IX.

On each investment election form filed by a Participant pursuant to this Section
9.3, the Participant shall designate the percentage increments for the
investment of his Contributions among the available Investment Funds. Such
designation shall be in percentage increments of 5 percent, unless the
Committee, in its discretion, provides for investments in percentage increments
other than 5 percent. The Contributions made by or on behalf of each Participant
shall be invested under the Plan in accordance with the investment election he
then has in effect with respect to such Contributions. Each such investment
election shall also be applicable with respect to any earnings or other income
attributable to the Contributions subject to such investment election.

9.4 INVESTMENT TRANSFERS

A Member may file an investment transfer election with respect to the balance
credited to his Accounts. Such investment transfer election shall be made on
such form or forms and in such manner as the Committee may prescribe from time
to time, and such investment transfer election shall become effective as of the
date established by the Committee, which shall establish periodic intervals
throughout the Plan Year (e.g., quarterly) and communicate such dates to
Members. On such investment transfer election form, the Member shall
designate the percentage increments for the investment of the balance credited
to his Accounts as of the effective date of his election. Such designation
shall be in percentage increments of 10




                                       39
   45

percent, unless the Committee, in its discretion provides for investments in
percentage increments other than 10 percent. From time to time, the Committee
may authorize alternative methods for effecting investment transfers, including
electronic or telephonic communications, in lieu of filing a prescribed written
form as provided in this Section 9.4. Any such authorized transfer method shall
be considered "filed" for purposes of this Article IX. All investment election
transfers shall be effected by liquidating the interest to be transferred from
one Fund to another Fund, and by reallocating such interest to the other Fund.
Any loss in value or adverse consequences resulting from such transfers shall
reduce the value of the amount to be transferred, as directed by the Member.
The Committee may restrict, delay or prohibit transfers in any Plan Year to the
extent the effecting of such transfers may tend to create adverse investment
results for one or more of the Funds.

9.5 RULES OF COMMITTEE

The Committee shall prescribe such rules and procedures from time to time as
deemed appropriate for investment elections and investment transfers under the
Plan. The Committee may also from time to time provide for limitations or
restrictions applicable to specific Contributions, Accounts and Investment
Funds. In the event a Participant fails to file or is unable to file an
investment election form prior to any date established in accordance with
Section 9.3, the Committee may prescribe procedures permitting the filing of
such investment election form on a later date to become effective as prescribed
by the Committee. The Committee may also prescribe procedures for the
investment of the Contributions made by or on behalf of a Participant who fails
to file an effective investment election pursuant to Section 9.3(a) or (b). The
Committee's rules and procedures relating to investment elections and
investment transfers shall be administered in a nondiscriminatory manner.

9.6 PURCHASE OF COMPANY STOCK AND PSA STOCK

Company Stock may be purchased by the Trustee in the open market or from the
Company in accordance with the terms of the Trust Agreement. If Company Stock
is purchased from the Company on a day such stock was traded on the open
market, the price of such Company Stock shall be the closing price of a Company
Stock on the open market on such day. If such stock was not traded on the open
market on the day of the purchase from the Company, then the price of such
Company Stock shall be the closing price of Company Stock on the open market
on the nearest date next preceding the date of the purchase. PSA Stock shall be
purchased by the





                                       40
   46

Trustee in such market or markets as may exist from time to time. All shares
and securities shall be held by the Trustee in its name or that of its nominee
and a Member shall not be deemed to have an interest in any particular
certificate of stock or security.

such officers or other Employees of the Employers and such other persons as the
Committee may appoint.

10.6 COMPENSATION AND EXPENSES

(a)  A member of the Committee shall serve without compensation for services as
     such if he is receiving full-time pay from the Employer as an Employee. Any
     such member who is not such an Employee may receive compensation for
     services, but paid by the Employer and not from the Trust Fund. Any such
     member may receive reimbursement by the Employer of expenses properly and
     actually incurred.

(b)  All expenses incurred in the administration of the Plan shall be paid by
     the Trustee from the Trust, unless the Company and/or other Employers elect

administration of the Plan, shall be preserved in the custody of the Committee.

A majority of the members of the Committee shall constitute a quorum for the
transaction of business. Actions taken by the Committee at any meeting at which
a quorum is present shall be by the vote of a majority of those present at any
such meeting. Action of the Committee may be taken without a meeting upon the
concurrence in writing of a majority of the members.

10.9 INFORMATION AND DATA FOR BENEFITS

All persons claiming benefits from the Plan must furnish to the Committee, such
documents, evidence, or information as the Committee considers necessary or
desirable for the purpose of administering the Plan; and each such person must
furnish such information promptly and sign such documents as the Committee may
reasonably require before any benefits become payable from the Plan.

10.10 FILING A CLAIM FOR BENEFITS

If a Member or Beneficiary does not receive the benefits which he believes he is
entitled to receive under the Plan, he may file a claim for benefits with the
Committee. All claims shall be made in writing and shall be signed by the
claimant. If the claimant does not furnish sufficient information to determine
the validity of the claim, the Committee shall indicate to the claimant any
additional information which is required.

10.11 APPEALS FROM DENIAL OF CLAIMS

If any claim for benefits under the Plan is wholly or partially denied, the
claimant shall be given notice in writing of such denial within 60 days setting
forth the following information: 

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

(b)  specific reference to pertinent Plan provisions on which denial is based;

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

(d)  an explanation that a full and fair review by the Committee of the decision
     denying the claim may be requested by the claimant or his authorized
     representative by filing with the Committee, within 60 days after such
     notice has been received, a written request for such review; and

(e)  if such request is so filed, the claimant or his authorized representative
     may review pertinent documents and submit issues and comments in




                                       45
   51

     writing within the same 60-day period specified in subsection (d) above.

The decision of the Committee shall be made promptly, and not later than 60 days
after the Committee's receipt of the request for review, unless special
circumstances require an extension of time for processing, in which case the
claimant shall be so notified and a decision shall be rendered as soon as
possible, but not later than 120 days after receipt of the request for review.
The claimant shall be given a copy of the decision promptly. The decision shall
be in writing and shall include specific reasons for the decision, written in a
manner calculated to be understood by the claimant, and specific references to
the pertinent Plan provisions on which the decision is based. The final decision
of the Committee shall be conclusive and binding on all having or claiming to
have an interest in the claim being reviewed and shall not be reversed by any
court unless the court shall find that the Committee's decision was arbitrary
and capricious.

10.12 INDEMNITY FOR LIABILITY

The Employer shall indemnify the members of the Committee, and each other
fiduciary who is an Employee of the Employer, against any and all claims,
losses, damages, expenses, including counsel fees, incurred by said fiduciaries
and any liability, including any amounts paid in settlement with approval of the
Employer and the fiduciary, arising from the fiduciary's action or failure to
act in connection with said fiduciary's responsibility under this Plan except
when the same is judicially determined to be attributable to the gross
negligence or willful misconduct of such fiduciary.

10.13 CONFLICTS

No member of the Committee shall participate in any determination by the
Committee of his rights or benefits under the Plan.

10.14 RELIANCE ON INFORMATION

The Committee may rely absolutely upon all information furnished by the
Employers or any Member, provided such information is received and accepted by
the Committee or its members in good faith as true and accurate. The Committee
may similarly rely on information furnished by anyone employed in good faith by
it, by the Employer, or by the Trustee, for the purpose for furnishing such
information.

10.15 BENEFICIARY DESIGNATION

(a)  Each unmarried Member may designate a Beneficiary or Beneficiaries under
     the Plan. He may, from time to time during his lifetime, on a form approved
     by and filed with the Committee, change his Beneficiary or Beneficiaries.

(b)  The Beneficiary of each Member who is married shall automatically be the
     surviving spouse of such Member, unless such spouse had consented in
     writing to the designation of another Beneficiary or Beneficiaries. Each
     married Member may, from time to time, change his designation of a
     Beneficiary or Beneficiaries; provided, however, that the Member may not
     change such designation without the written consent of his spouse. Any such
     written consent must satisfy the requirements of Section 10.15(e).

(c)  The Beneficiary or Beneficiaries of a Member shall receive the benefits
     payable under the Plan in the event of the Member's death. All Beneficiary
     designations, and the written consents provided for in Section 10.15(b),
     shall be on such form or forms as may be prescribed by the Committee. No
     Beneficiary designation shall be effective for any purpose until it has
     been filed with the Committee during the lifetime of the Member. On each
     Beneficiary designation, the Member shall name a primary Beneficiary or
     Beneficiaries and may name a contingent Beneficiary or Beneficiaries.

(d)  In the event that a Member fails to designate a Beneficiary or
     Beneficiaries, or if for any reason such designation shall be legally
     ineffective, or if all designated Beneficiaries predecease him or die
     simultaneously with him, distribution shall be made to his estate.

(e)  The written consent described in Section 10.15(b) shall not be effective
     unless (i) the spouse has consented in writing to the designation of
     another Beneficiary or Beneficiaries, (ii) such designation designates
     another Beneficiary or Beneficiaries (or a form of benefits) which may not
     be changed without written spousal consent (or the consent of the spouse
     expressly permits designations by the Member without any requirement of
     further consent by the spouse), and (iii) the spouse's consent acknowledges
     the effect of such designation and is witnessed by a Plan representative or
     a notary public. Such consent shall not be required if the Member
     establishes to the satisfaction of the Committee that such consent may not
     be obtained because there is no spouse, because the spouse cannot be
     located or because of such other circumstances as the Secretary of the
     Treasury may prescribe by regulation.





                                       47
   53

10.16 INCOMPETENCY

Every person receiving or claiming benefits under the Plan shall be conclusively
presumed to be mentally competent until the date on which the Committee receives
a written notice, in a form and manner acceptable to it, that such person is
incompetent, for whom a guardian or other person legally vested with the care of
his estate has been appointed; provided, however, that if the Committee shall
find that any person to whom a benefit is payable under the Plan is unable to
care for his affairs because of any disability or infirmity, any payment due
(unless a prior claim therefor shall have been made by a duly appointed legal
representative of his estate) may be paid to the spouse, a child, a parent, or a
brother or sister. Any such payment so made shall be a complete discharge of any
liability therefor under the Plan. In the event a guardian of the estate of any
person receiving or claiming benefits under the Plan shall be appointed by a
court of competent jurisdiction, benefit payments may be made to such guardian
provided that proper proof of appointment and continuing qualification is
furnished in a form and manner acceptable to the Committee. Any such payment so
made shall be a complete discharge of any liability therefor under the Plan.

10.17 NO ENLARGEMENT OF EMPLOYEE RIGHTS

Nothing contained in this Plan shall give any Employee the right to be retained
in the service of an Employer or to interfere with the right of an Employer to
discipline, discharge or retire any Employee at any time.

10.18 APPLICABLE LAW

The Plan and all rights hereunder shall be governed by and construed according
to the laws of the State of Texas to the extent such laws have not been
preempted by applicable Federal laws.

10.19 INTERNAL REVENUE SERVICE APPROVAL

It is the intention of the Company to obtain a ruling or rulings by the District
Director of the Internal Revenue Service that the Plan, as in effect from time
to time, with respect to all Employers, meets the requirements of Code Section
401(a).

10.20 SEVERABILITY

If a provision of the Plan shall be held illegal or invalid, the illegality or
invalidity shall not affect the remaining parts of the Plan and the Plan shall
be construed and enforced as if the illegal or invalid provision had not been
included in the Plan.

10.21  EFFECTIVE DATES FOR CERTAIN PROVISIONS

(a)  As a result of changes made by the Tax Reform Act of 1986, certain changes
     to the Code relating to qualified plans and trusts have become effective as
     to the Plan for its Plan Year beginning January 1, 1987. Since such
     effective date precedes the effective date of this amended and restated
     Plan, it is the intent that certain provisions in the Plan retroactively
     applied as of January 1, 1987 to the prior Plan document. Accordingly, any
     and all amendments reflected in the Plan as amended and restated effective
     as of January 1, 1989 which relate to such changes as are required by the
     Tax Reform Act of 1986 and other applicable changes to the Code, and which
     would be required to be made under the Plan effective as of a date earlier
     than January 1, 1989 shall be deemed to be amendments to the Plan which are
     effective as required by the Tax Reform Act of 1986. Such amendments shall
     include, without limitation, the provisions in Section 8.1 (relating to
     Code section 415 limits) and Article XIII (relating to top-heavy
     provisions) to be effective as of January 1, 1987. All such amendments
     shall be administratively applied under the provisions of the Plan as if
     the content thereof had been included in a separate amendment to the prior
     Plan document.

ARTICLE XI. TRUST FUND AND TRUSTEE

11.1 ESTABLISHMENT OF TRUST FUND

The Company has entered into a Trust Agreement with the Trustee in order to
implement and carry out the provisions of the Plan and to finance the benefits
provided for under the Plan. The Company may amend or modify the Trust Agreement
in accordance with the terms of the Trust Agreement from time to time to
accomplish the purposes of the Plan. Pursuant to the Trust Agreement, a Trust
Fund was created and is to be maintained to carry out the purposes of the Plan,
and the funds held as part of the Trust Fund are to be invested in accordance
with the terms of the Trust Agreement and, where applicable, the Plan. The
declaration of trust created under the Trust Agreement forms a part of the Plan.
The Employers shall make such Contributions to the Trust Fund as are required by
the provisions of the Plan, subject to the right of the Company to amend, modify
or terminate the Plan at any time, and all benefits under the Plan shall be paid
from the Trust Fund. All rights which may accrue to any Member, Beneficiary or
other person under the Plan shall be subject to all the terms and provisions of
the Plan and Trust Agreement.

11.2 TRUSTEE

The Trustee of the Trust Fund shall be the Trustee provided for under the Plan
and the Trust Agreement as in effect from time to time, or any trust instrument
substituted for such Trust Agreement. The Trustee's obligations, duties and
responsibilities shall be governed by the terms of the Trust Agreement, or such
other trust instrument as may be in effect, and, where applicable, by the terms
of the Plan.

11.3 RIGHTS IN THE TRUST FUND

Members or any other person eligible for or claiming benefits under the Plan
shall be entitled to look only to the Trust Fund for the payment of such
benefits and shall have no claim against any Employer, the Committee or any
other person. No person shall have any right or interest in the Trust Fund
except as expressly provided in the Plan. Except to the extent, if any, that
Section 410 of ERISA may otherwise require, in no event shall the Employers, or
any of their officers, directors, Employees, or the members of the Committee be
liable in their individual capacities to any person whomsoever, under the
provisions of the Plan or Trust Agreement.




                                       50

   56

11.4 NONREVERSION; EXCLUSIVE BENEFIT

The Trust Fund shall be used and applied only in accordance with the provisions
of the Plan and Trust Agreement, to provide the benefits provided under the
Plan. No Employers shall have any right, title or interest in the assets of the
Trust Fund, and no part of the corpus or income of the Trust Fund shall be used
for, or diverted to, purposes other than for the exclusive benefit of Members
and their Beneficiaries and for the payment of the reasonable expenses of
administering the Plan and Trust, except that if Contributions are made to the
Trust Fund by an Employer by a mistake of fact, then such Contributions may be
returned to such Employer within one year after the payment of such
Contributions; and if any part or all of the Contributions are disallowed as a
deduction under Code section 404, then to the extent such Contributions are
disallowed as a deduction they may be returned to such Employer within one year
after the disallowance; provided, however, that any earnings attributable to
Contributions made by mistake of fact or disallowed as a deduction under Code
section 404 shall not be returned to the Employer, but losses attributable
thereto must reduce the amount returned.

11.5 NONALIENATION

Except as provided in Code section 401(a)(13), neither benefits payable at any
time under the Plan nor the corpus or income of the Trust Fund shall be subject
in any manner to alienation, sale, transfer, assignment, pledge, attachment,
garnishment, or encumbrance of any kind. Any attempt to alienate, sell,
transfer, assign, pledge, or otherwise encumber any such benefit, whether
presently or thereafter payable, shall be void. No benefit nor the Trust Fund
shall in any manner be liable for or subject to the debts or liabilities of any
Member or of any other person entitled to any benefit. The Committee shall
establish procedures to determine whether domestic relations orders are
"qualified domestic relations orders" and to administer distributions under such
qualified domestic relations orders.

11.6 MERGER, CONSOLIDATION OR TRANSFER

In the case of any merger or consolidation of the Plan with, or in the case of
any transfer of assets or liabilities of the Plan to or from, any other plan,
each Member shall receive a benefit immediately after the merger, consolidation,
or transfer (if the Plan had then terminated) which is equal to or greater than
the benefit he would have been entitled to receive immediately before the
merger, consolidation, or transfer (if the Plan had then terminated).

ARTICLE XII. AMENDMENT AND TERMINATION

12.1 AMENDMENT AND TERMINATION

(a)  The Company does hereby expressly and specifically reserve the sole and
     exclusive right at any time by action of the Board of Directors to amend,
     modify, or terminate the Plan. The Company's right of amendment,
     modification, or termination shall not be subject to the consent or
     concurrence of any other Employer, the Trustee, any Member or any other
     interested party, nor shall such right be subject to any action by any
     other Employer notwithstanding that such action by the Company may relate
     in whole or in part to persons in the employ of such Employer.

(b)  While each Employer contemplates carrying out the provisions of the Plan
     indefinitely with respect to its Employees, no Employer shall be under any
     obligation or liability whatsoever to maintain the Plan for any minimum or
     other period of time.

(c)  Any action taken to amend, modify or terminate the Plan shall be evidenced
     by a written instrument duly executed and/or certified by an officer of the
     Company. Any such instrument evidencing an amendment to the Plan shall be
     delivered by the Company to the Committee, the Trustee and each other
     Employer.

(d)  Upon any termination of the Plan in its entirety, or with respect to any
     Employer, the Company shall give written notice thereof to the Committee,
     the Trustee, and any Employer involved.

(e)  Except as provided by law, upon any termination of the Plan, no Employer
     with respect to whom the Plan is terminated (including the Company) shall
     thereafter be under any obligation, liability, or responsibility whatsoever
     to make any contribution or payment to the Trust Fund, the Plan, any Member
     or any other person, trust or fund whatsoever, for any purpose whatsoever
     under or in connection with the Plan.

(f)  In the event the Plan is terminated, the Plan is partially terminated or
     Contributions under the Plan are completely discontinued, the rights of all
     Members (or in the case of a partial termination, the Members affected
     thereby) to the amounts credited to their Accounts shall continue to be
     fully vested and nonforfeitable.

12.2 LIMITATIONS ON AMENDMENTS

The provisions of this Article XII relating to amendments shall be subject to
and limited by the following restrictions:

(a)  No amendment shall operate either directly or indirectly to give any
     Employer any interest whatsoever in any funds or property held by the
     Trustee under the terms of the Plan, or to permit the corpus or



                                       52
   58
     income of the Trust to be used for or diverted to purposes other than the
     exclusive benefit of Members or the payment of the reasonable expenses of
     administering the Plan.

(b)  No such amendment shall operate either directly or indirectly to deprive
     any Member of his vested and nonforfeitable interest as of the time of such
     amendment.

(c)  No amendment shall change the rights, duties or responsibilities of the
     Trustee under the Plan without its written consent.

(d)  Subject to the foregoing limits, the Committee shall have the authority to
     amend the Plan (either retroactively or prospectively) as it deems
     necessary or advisable with respect to the operation and administration of
     the Plan that is within the scope of the responsibility and authority of
     the Committee as established in Article X, including any modification or
     amendments necessary to comply with any laws or regulations to qualify as a
     tax-exempt Plan and Trust. The Committee shall not have the authority to
     amend the principal design characteristics of the Plan, such authority
     being exclusively reserved to the Board of Directors.

12.3 EFFECT OF BANKRUPTCY AND OTHER CONTINGENCIES AFFECTING AN EMPLOYER

In the event an Employer terminates its participation in the Plan, or in the
event an Employer is dissolved, liquidated, or shall by appropriate legal
proceedings be adjudged bankrupt, or in the event judicial proceedings of any
kind result in the involuntary dissolution of an Employer, participation in the
Plan shall be terminated with respect to such Employer. The merger,
consolidation, or reorganization of an Employer, or the sale by it of all or
substantially all of its assets, shall not terminate the Plan if there is
delivery to such Employer by the Employer's successor or by the purchaser of all
or substantially all of the Employer's assets, of a written instrument
requesting that the successor or purchaser be substituted for the Employer and
agreeing to perform all the provisions hereof which such Employer is required
to perform. Upon the receipt of said instrument, with the approval of the
Company, the successor or the purchaser shall be substituted for such Employer
under the Plan, and such Employer shall be relieved and released from any
obligations of any kind, character, or description herein or in any Trust
Agreement imposed upon it.

12.4 DISTRIBUTIONS ON PLAN TERMINATION

In the event of the termination of the Plan in its entirety, or with respect to
any Employer, the Company may prescribe, or instruct the Committee to
prescribe, a method for making distributions from the Plan following such



                                       53
   59
termination; provided, however, that distribution of Before-Tax Contribution
Accounts shall only occur in accordance with the provisions of Code section
401(k)(10) relating to distributions upon termination of a Plan and applicable
Treasury regulations. Such method of distribution may provide for termination
distributions to be made as soon as practicable following such termination, and
may permit the Members to elect the form and method of their distributions. If
such termination distributions are not provided for, distributions and payments
shall be made to Members in accordance with the provisions of Article VII. In
any such case, the Committee shall instruct the Trustee as to the making of Plan
distributions following any such Plan termination.

ARTICLE XIII. PARTICIPATION IN AND WITHDRAWAL FROM THE PLAN BY AN EMPLOYER

13.1 PARTICIPATION IN THE PLAN

Any Affiliate which desires to become a participating Employer under the Plan
may elect, with the consent of the Board of Directors, to become a party to the
Plan and Trust Fund by adopting the Plan for the benefit of its Eligible
Employees, effective as of the date specified in such adoption--

(a)  By filing with the Company a certified copy of a resolution of its board of
     directors (or equivalent governing authority) to that effect and such other
     instruments as the Company may require; and

(b)  By the Company's filing with the Committee and the Trustee a copy of such
     resolution, together with a certified copy of resolutions of the Board of
     Directors approving such adoption.

The adoption resolution or decision may contain such specific changes and
variations in Plan or Trust Agreement terms and provisions applicable to such
adopting Employer and its Employees as may be acceptable to the Company and the
Trustee. The adoption resolution or decision shall become, as to such adopting
organization and its employees, a part of this Plan as then amended or
thereafter amended and the related Trust Agreement. It shall not be necessary
for the adopting organization to sign or execute the original Plan and Trust
Agreement documents. The coverage date of the Plan for any such adopting
organization shall be that stated in the resolution or decision of adoption,
and from and after such effective date, such adopting organization shall assume
all the rights, obligations, and liabilities of an Employer hereunder and under
the Trust Agreement. The administrative powers and control of the Company, as
provided in the Plan and Trust Agreement, including the right to amend or
terminate the Plan and the Trust Agreement, the right to appoint and remove the
Committee members and the Trustee, shall not be diminished by reason of the
participation in the Plan of any adopting Employer.

13.2 WITHDRAWAL FROM THE PLAN

Any Employer, other than the Company, by action of its board of directors or
other governing body, may elect to withdraw from the Plan and Trust Agreement by
giving 90 days' advance written notice of its election to the Board of
Directors, unless the Board of Directors waives such advance notice or agrees to
a shorter advance notice period. Such Employer's election to withdraw from the
Plan and Trust Agreement shall be subject to the consent of the Board of
Directors. Distributions following such withdrawal may be implemented through
continuation of the Trust Fund,



                                       55
   61
or transfer to another trust fund exempt from tax under Code section 501, or to
a group annuity contract qualified under Code section 401, or distributions may
be made as immediate distributions in accordance with the directions of the
Committee; provided, however, that no such action shall direct any part of the
Trust Fund relating to the Participants of such Employer to any purpose other
than the exclusive benefit of the Participants of such Employer, or the
surviving spouses or Beneficiaries of such Participants, prior to the
satisfaction of all benefit liabilities under the Plan with respect to the
Participants of such Employer.

     of a Determination Date, the sum of the amount of the Section 416 Accounts
     of Key Employees and the Beneficiaries of deceased Key Employees exceeds 60
     percent of the amount of the Section 416 Accounts of all Members and
     Beneficiaries (excluding former Key Employees), the Plan is top-heavy and
     the provisions of this Article XIV shall become applicable.

(b)  AGGREGATION GROUP DETERMINATION.

     (1)  If as of a Determination Date the Plan is part of an Aggregation Group
          which is top-heavy, the provisions of this Article XIV shall become
          applicable. Top-heaviness for the purpose of this Section 14.1(b)(1)
          shall be determined with respect to the Aggregation Group in the same
          manner as described in Section 14.1(a).

     (2)  If the Plan is top-heavy under Section 14.1(a), but the Aggregation
          Group is not top-heavy, the Plan shall not be top-heavy and this
          Article XIV shall not be applicable.

(c)  COMMITTEE. The Committee shall have responsibility to make all calculations
     to determine whether the Plan is top-heavy.

14.2 DEFINITIONS

(a)  "AGGREGATION GROUP" means the Plan and all other plans maintained by the
     Employers and Affiliates which cover a Key Employee and any other plan
     which enables a plan covering a Key Employee to meet the requirements of
     Code section 401(a)(4) or 410. In addition, at the election of the
     Committee, the Aggregation Group may be expanded to include any other
     qualified plan maintained by an Employer or Affiliate if such expanded
     Aggregation Group meets the requirements of Code sections 401(a)(4) and
     410. 

(b)  "DETERMINATION DATE" means the last day of the Plan Year immediately
     preceding the Plan Year for which top-heaviness is to be determined or, in
     the case of the first Plan Year of a new plan, the last day of such Plan
     Year. 

(c)  "KEY EMPLOYEE" means a Member who for the Plan Year containing the

          greater than 50 percent of the amount in effect under Code section
          415(b)(1)(A) for such Plan Year; provided, however, that no more than
          the lesser of--



                                       57
   63

          (A)  50 Employees, or

          (B)  the greater of (i) three Employees or (ii) 10 percent of all
               Employees,

          shall be treated as officers, and such officers shall be those with
          the highest annual Compensation in the five-year period;

     (2)  One of the ten Employees having annual Compensation from all Employers
          and Affiliates for such Plan Year greater than the dollar limit
          specified in Code section 415(c)(1)(A) and owning both more than a
          one-half of 1 percent interest and the largest interests in an
          Employer or Affiliate;

     (3)  A 5 percent owner of an Employer or Affiliate; or

     (4)  A 1 percent owner of an Employer or Affiliate having annual
          Compensation of more than $150,000.

     Ownership shall be determined in accordance with Code section 416(i)(1)(B)
     and (C). For purposes of Section 14.2(c)(2), if two Employees have the same
     ownership interest in an Employer or Affiliate, the Employee having the

     treated as having a larger interest.

(d)  "SECTION 416 ACCOUNT" means

     (1)  The amount credited as of a Determination Date to a Member's or
          Beneficiary's account, under the Plan and under any other qualified
          defined contribution plan which is part of an Aggregation Group

          which have not yet been contributed);

     (2)  The present value of the accrued benefit credited to a Member or
          Beneficiary under a qualified defined benefit plan which is part of an
          Aggregation Group; and

     (3)  The amount of distributions to the Member or Beneficiary during the
          five-year period ending on the Determination Date other than a

          by--

     (4)  The amount of rollover contributions (or similar transfers) and
          earnings thereon credited as of a Determination Date under a plan

          31, 1983, initiated by the Member and derived from a plan not
          maintained by an Employer or Affiliate.

     The account of a Member who was a Key Employee and who subsequently meets
     none of the conditions of Section 14.2(c) for the




                  58
   64

     Plan Year containing the Determination Date is not a Section 416 Account
     and shall be excluded from all computations under this Article XIV.
     Furthermore, if a Member has not performed any services for an Employer or
     Affiliate during the five year period ending on the Determination Date, any
     account of such Member (and any accrued benefit for such Member) shall not
     be taken into account in computing top-heaviness under this Article XIV.

14.3 MINIMUM CONTRIBUTION

(a)  GENERAL. If the Plan is determined to be top-heavy under the provisions of
     Section 14.1 with respect to a Plan Year, the sum of employer contributions
     (excluding contributions under a salary reduction agreement only for
     non-Key Employees) and forfeitures under all qualified defined contribution
     plans allocated to the accounts of each Member in the Aggregation Group who
     is not a Key Employee (determined without regard to whether such Member
     completed any minimum Period of Service or made Before-Tax Contributions
     for such Plan Year) and is an Employee on the last day of the Plan Year
     shall not be less than 3 percent of such Member's Compensation. This
     Section 14.3 shall not be applicable with respect to a Member who is also
     covered under a defined benefit plan maintained by an Employer or an
     Affiliate which provides the benefit specified by Code section 416(c)(1).

(b)  EXCEPTION. The contribution rate specified in Section 14.3(a) shall not
     exceed the percentage at which employer contributions and forfeitures are
     allocated under the plans of the Aggregation Group to the account of the
     Key Employee for whom such percentage is the highest for the Plan Year. For
     the purpose of this Section 14.3(b), the percentage for each Key Employee
     shall be determined by dividing the employer contributions and forfeitures
     for the Key Employee by the amount of his total Compensation for the year
     (as determined under the provisions of Section 2.1(i)).

14.4 LIMIT ON ANNUAL ADDITIONS: COMBINED PLAN LIMIT

(a)  GENERAL. If the Plan is determined to be top-heavy under Section 14.1,
     Section 8.4 of the Plan shall be applied by substituting 1.0 for 1.25 in
     applying the provisions of Code section 415(e)(2) and (e)(3). The
     transitional rule of Code section 415(e)(6)(B)(i) shall be applied by
     substituting "$41,500" for "$51,875."

(b)  EXCEPTION. Section 14.4(a) shall not be applicable if--




                                       59
   65

     (1)  Section 14.3 is applied by substituting "4 percent" for "3 percent,"
          and 

     (2)  the Plan would not be top-heavy if "90 percent" is substituted for
          "60 percent" in Section 14.1. 

(c)  TRANSITIONAL RULE. If, but for this Section 14.4(c), Section 14.4(a) would
     begin to apply with respect to the Plan, the application of Section 14.4(a)
     shall be suspended with respect to a Member so long as there are--

     (1)  no employer contributions, forfeitures, or voluntary nondeductible
          contributions allocated to such Member, and 

     (2)  no accruals under a qualified defined benefit plan for such Member.

14.5 COLLECTIVE BARGAINING AGREEMENTS

The requirements of Section 14.3 shall not apply with respect to any Employee
included in a unit of Employees covered by a collective bargaining agreement
between Employee representatives and an Employer or Affiliate if retirement
benefits were the subject of good faith bargaining between such Employee
representatives and such Employer or Affiliate.

                                     to the
                         FINA CAPITAL ACCUMULATION PLAN
             (Amended and Restated Effective as of January 1, 1989)

WHEREAS, FINA, Inc. ("Company") maintains the "FINA Capital Accumulation Plan,"
as amended and restated effective January 1, 1989 ("Plan");

WHEREAS, the Company desires to amend the Plan to allow after-tax contributions
up to 6 percent of compensation, to provide a match on all contributions (both

          provided, however, that no such Matching Contribution shall be made
          for any pay period which is in excess of 6 percent of the Active

          allocated first to Before-Tax Contributions and, if such Before-Tax
          Contributions are less than the 6 percent aggregate limit, next to
          After-Tax Contributions.

3.   Paragraph (c) of Section 7.5 of the Plan is amended, effective January 1,

    6.   Section 9.6 of the Plan is amended in its entirety to read as follows:

    9.6  COMPANY STOCK, PSA STOCK AND ADSs

    Company Stock may be purchased by the Trustee in the open market or from the
    Company in accordance with the terms of the Trust Agreement. If Company
    Stock is purchased from the Company on a day such stock is traded on the
    open market, the price of such Company Stock shall be the closing price of
    the Company Stock on the open market on such day. If the Company Stock is
    not traded on the open market on the day of the purchase from the Company,
    then the price of the Company Stock shall be the closing price of the
    Company Stock on the open market on the nearest date next preceding the date
    of the purchase.

    From and after April 1, 1998, or such later date as the Committee determines
    in its discretion, the Plan shall no longer invest in PSA Stock and instead

    in accordance with such rules and procedures as the Committee in its
    discretion may establish, including without limitation rules and procedures
    governing period of time in which such sale or exchange shall be
    accomplished.

    exchangeable for Company Stock are distributed to holders of the Company
    Stock, the Committee shall cause the Trustee to sell such securities as
    promptly as possible, consistent with the Trustee's duty of prudence, and to
    reinvest the proceeds of the sale of such securities in Company Stock, as
    applicable.

by its duly authorized officer this 19th day of February, 1998.
