benefit of eligible employees of the Company and its participating affiliates.
Effective January 1, 1994, the Money Purchase Pension Plan for Employees of

trust agreement which is entered into by and between Spieker Properties, L.P.
and BZW Barclays Global Investors, National Association. The Trust is intended
to be tax exempt as described under Code section 501(a).

The Plan constitutes an amendment and restatement of the Spieker Properties
Retirement Savings Plan effective October 1, 1996, which was last amended and
restated effective January 1, 1994, and its related trust agreement.

The Spieker Properties Retirement Savings Plan and Trust, as set forth in this

                   Notwithstanding, a Year of Vesting Service for periods
                   commencing January 1, 1990 through December 31, 1993, is a 12
                   consecutive month period ending on the last day of a Plan
                   Year in which an Employee is credited with at least 1,000
                   Hours of Service and a Year of Vesting Service for periods
                   prior to January 1, 1990 is a 12 consecutive month period
                   ending on the anniversary date of an Employee's hire date, or
                   as that date may be adjusted as a result of termination of
                   employment and reemployment, in which an Employee is credited
                   with at least 1,000 Hours of Service. Each Hour of Service
                   during the portion of the 1990 Plan Year where two 12
                   consecutive month periods overlapped were counted for
                   purposes of both 12 consecutive month periods.

                   Years of Vesting Service shall include service credited prior
                   to September 1, 1987.

2        ELIGIBILITY

         2.1       Eligibility

                   All Participants as of October 1, 1996 shall continue their
                   eligibility to participate.

                   For purposes of 401(k) Contributions, each other Eligible
                   Employee shall become a Participant on the later of October
                   1, 1996 or on the first day of employment as an Eligible
                   Employee.

                   For all other purposes, each other Eligible Employee shall
                   become a Participant on the first day of the next payroll
                   period after the date he or she completes a 12 month
                   eligibility period in which he or she is credited with at
                   least 1,000 Hours of Service. The initial eligibility period
                   begins on the date an Employee first performs an Hour of
                   Service. Subsequent eligibility periods begin with the start
                   of each Plan Year beginning after the first Hour of Service
                   is performed.

         2.2       Ineligible Employees

                   If an Employee completes the above eligibility requirements,
                   but is Ineligible at the time participation would otherwise
                   begin (if he or she were not Ineligible), he or she shall
                   become a Participant on the first subsequent date on which he
                   or she is an Eligible Employee.

         2.3       Ineligible or Former Participants

                   A Participant may not make or share in Plan Contributions,
                   nor generally be eligible for a new Plan loan, during the
                   period he or she is Ineligible, but he or she shall continue
                   to participate for all other purposes. An Ineligible
                   Participant or former Participant shall automatically become
                   an active Participant on the date he or she again becomes an
                   Eligible Employee.

3        PARTICIPANT CONTRIBUTIONS

         3.1       401(k) Contribution Election

                   Upon becoming a Participant, an Eligible Employee may elect
                   to reduce his or her Pay by an amount which does not exceed
                   the Contribution Dollar Limit, within the limits described in
                   the Contribution Percentage Limits paragraph of this Section
                   3, and have such amount contributed to the Plan by the
                   Employer as a 401(k) Contribution. The election shall be made
                   as a whole percentage of Pay in such manner and with such
                   advance notice as prescribed by the Administrator. In no
                   event shall an Employee's 401(k) Contributions under the Plan
                   and comparable contributions to all other plans, contracts or
                   arrangements of all Related Companies exceed the Contribution
                   Dollar Limit for the Employee's taxable year beginning in the
                   Plan Year.

         3.2       Changing a Contribution Election

                   A Participant who is an Eligible Employee may change his or
                   her 401(k) Contribution election at any time in such manner
                   and with such advance notice as prescribed by the
                   Administrator, and such election shall be effective with the
                   first payroll paid after such date. Participants'
                   Contribution election percentages shall automatically apply
                   to Pay increases or decreases.

         3.3       Revoking and Resuming a Contribution Election

                   A Participant may revoke his or her 401(k) Contribution
                   election at any time in such manner and with such advance
                   notice as prescribed by the Administrator, and such
                   revocation shall be effective with the first payroll paid
                   after such date.

                   A Participant who is an Eligible Employee may resume 401(k)
                   Contributions by making a new 401(k) Contribution election at
                   any time in such manner and with such advance notice as
                   prescribed by the Administrator, and such election shall be
                   effective with the first payroll paid after such date.

         3.4       Contribution Percentage Limits

                   The Administrator may establish and change from time to time,
                   in writing, without the necessity of amending the Plan and
                   Trust, the minimum, if applicable, and maximum 401(k)
                   Contribution percentages, prospectively or retrospectively
                   (for the current Plan Year), for all Participants. In
                   addition, the Administrator may establish any lower
                   percentage limits for Highly Compensated Employees as it
                   deems necessary to satisfy the tests described in Section 12.
                   As of the Effective Date, the 401(k) Contribution minimum
                   percentage is 1% and the maximum percentage is 15%.

<PAGE>   18
                   Irrespective of the limits that may be established by the
                   Administrator in accordance with the paragraph above, in no
                   event shall the contributions made by or on behalf of a
                   Participant for a Plan Year exceed the maximum allowable
                   under Code section 415.

         3.5       Refunds When Contribution Dollar Limit Exceeded

                   A Participant who makes 401(k) Contributions for a calendar
                   year to the Plan and comparable contributions to any other
                   qualified defined contribution plan in excess of the
                   Contribution Dollar Limit may notify the Administrator in
                   writing by the following March 1 (or as late as April 14 if
                   allowed by the Administrator) that an excess has occurred. In
                   this event, the amount of the excess specified by the
                   Participant, adjusted for investment gain or loss, shall be
                   refunded to him or her by April 15 and shall not be included
                   as an Annual Addition under Code section 415 for the year
                   contributed. Refunds shall not include investment gain or
                   loss for the period between the end of the applicable
                   calendar year and the date of distribution. The excess
                   amounts shall first be taken from unmatched 401(k)
                   Contributions and then from matched 401(k) Contributions. Any
                   Spieker Match Contributions attributable to refunded excess
                   401(k) Contributions as described in this Section shall be
                   forfeited and used as described in Section 8.5.

         3.6       Timing, Posting and Tax Considerations

                   Participants' Contributions, other than Rollover
                   Contributions, may only be made through payroll deduction.
                   Such amounts shall be paid to the Trustee in cash and posted
                   to each Participant's Account(s) as soon as such amounts can
                   reasonably be separated from the Employer's general assets
                   and balanced against the specific amount made on behalf of
                   each Participant. In no event, however, shall such amounts be
                   paid to the Trustee more than 90 days after the date amounts
                   are deducted from a Participant's Pay, except that effective
                   February 3, 1997, "15 business days following the end of the
                   month that includes the date amounts are deducted from a
                   Participant's Pay (or as that maximum period may be extended
                   for such amounts for a single month subject to the Employer's
                   compliance with an extension procedure provided under ERISA)"
                   shall be substituted for the preceding reference to "90 days
                   after the date amounts are deducted from a Participant's
                   Pay". 401(k) Contributions shall be treated as Contributions
                   made by an Employer in determining tax deductions under Code
                   section 404(a).

4        ROLLOVER CONTRIBUTIONS AND TRANSFERS FROM AND TO OTHER QUALIFIED
         PLANS

         4.1       Rollover Contributions

                   The Administrator may authorize the Trustee to accept a
                   Rollover Contribution in cash, directly from an Eligible
                   Employee or as a Direct Rollover from another qualified plan
                   on behalf of the Eligible Employee, even if he or she is not
                   yet a Participant. The Employee shall be responsible for
                   providing satisfactory evidence, in such manner as prescribed
                   by the Administrator, that the amount qualifies as a rollover
                   contribution, within the meaning of Code section 402(c) or
                   408(d)(3)(A)(ii). Such amounts received directly from an
                   Eligible Employee must be paid to the Trustee in cash within
                   60 days after the date received by the Eligible Employee from
                   a qualified plan or conduit individual retirement account.
                   Rollover Contributions shall be posted to the Eligible
                   Employee's Rollover Account as of the date received by the
                   Trustee.

                   If the Administrator later determines that an amount
                   contributed pursuant to the above paragraph did not in fact
                   qualify as a rollover contribution, within the meaning of
                   Code section 402(c) or 408(d)(3)(A)(ii), the balance credited
                   to the Participant's Rollover Account shall immediately be
                   (1) segregated from all other Plan assets, (2) treated as a
                   nonqualified trust established by and for the benefit of the
                   Participant, and (3) distributed to the Participant. Any such
                   amount shall be deemed never to have been a part of the Plan.

         4.2       Transfers From and To Other Qualified Plans

                   The Administrator may instruct the Trustee to receive assets
                   in cash or in-kind directly from another qualified plan or
                   transfer assets in cash or in-kind directly to another
                   qualified plan; provided that receipt of a transfer should
                   not be directed if:

                   (a)      any amounts are not exempted by Code section
                            401(a)(11)(B) from the annuity requirements of Code
                            section 417 unless the Plan complies with such
                            requirements; or

                   (b)      any amounts include benefits protected by Code
                            section 411(d)(6) which would not be preserved under
                            applicable Plan provisions.

                   The Trustee may refuse the receipt of any transfer if:

                   (a)      the Trustee finds the in-kind assets unacceptable;
                            or

                   (b)      instructions for posting amounts to Participants'
                            Accounts are incomplete.

                   Such amounts shall be posted to the appropriate Accounts of
                   Participants as of the date received by the Trustee.

                            be made based upon a Participant's Contributions in

6        ACCOUNTING

         6.1       Individual Participant Accounting

                   The Administrator shall maintain an individual set of
                   Accounts for each Participant in order to reflect
                   transactions both by type of Account and investment medium.
                   Financial transactions shall be accounted for at the
                   individual Account level by posting each transaction to the
                   appropriate Account of each affected Participant. Participant
                   Account values shall be maintained in shares for the
                   Investment Funds and in dollars for the Sweep and Loan
                   Accounts. At any point in time, the Account value shall be
                   determined using the most recent Trade Date values provided
                   by the Trustee.

         6.2       Sweep Account is Transaction Account

                   All transactions related to amounts being contributed to or
                   distributed from the Trust shall be posted to each affected
                   Participant's Sweep Account. Any amount held in the Sweep
                   Account shall be credited with interest up until the date on
                   which it is removed from the Sweep Account.

         6.3       Trade Date Accounting and Investment Cycle

                   Participant Account values shall be determined as of each
                   Trade Date. For any transaction to be processed as of a Trade
                   Date, the Trustee must receive instructions for the
                   transaction by the Sweep Date. Such instructions shall apply
                   to amounts held in the Account on that Sweep Date. Financial
                   transactions of the Investment Funds shall be posted to
                   Participants' Accounts as of the Trade Date, based upon the
                   Trade Date values provided by the Trustee, and settled on the
                   Settlement Date.

         6.4       Accounting for Investment Funds

                   Investments in each Investment Fund shall be maintained in
                   shares. The Trustee is responsible for determining the share
                   values of each Investment Fund as of each Trade Date. To the
                   extent an Investment Fund is comprised of collective
                   investment funds of the Trustee, or any other fiduciary to
                   the Plan, the share values shall be determined in accordance
                   with the rules governing such collective investment funds,
                   which are incorporated herein by reference. All other share
                   values shall be determined by the Trustee. The share value of
                   each Investment Fund shall be based on the fair market value
                   of its underlying assets.

         6.5       Payment of Fees and Expenses

                   Except to the extent Plan fees and expenses related to
                   Account maintenance, transaction and Investment Fund
                   management and maintenance, set forth below, are paid by the
                   Employer directly, or indirectly, through the Forfeiture
                   Account as directed by the Administrator, such fees and
                   expenses shall be paid

                   the fees and expenses allocable to the Accounts of
                   Participants who are no longer Employees or who are not

                            a per Participant basis provided that no fee shall
                            reduce a Participant's Account balance below zero.

                   (b)      Transaction: Transaction fees and expenses, may
                            include but are not limited to, periodic installment

                            provided that no fee shall reduce a Participant's
                            Account balance below zero.

                   (c)      Investment Fund Management and Maintenance:
                            Management and maintenance fees and expenses related
                            to the Investment Funds shall be charged at the
                            Investment Fund level and reflected in the net gain
                            or loss of each Fund.

                   As of the Effective Date, a breakdown of which Plan fees and
                   expenses shall generally be borne by the Trust (and charged
                   to individual Participants' Accounts or charged at the
                   Investment Fund level and reflected in the net gain or loss
                   of each Fund) and those that shall be paid by the Employer is
                   set forth in Appendix B and may be changed from time to time
                   by the Administrator, in writing, without the necessity of
                   amending the Plan and Trust.

                   The Trustee shall have the authority to pay any such fees and
                   expenses, which remain unpaid by the Employer for 60 days,
                   from the Trust.

         6.6       Accounting for Participant Loans

                   Participant loans shall be held in a separate Loan Account of
                   the Participant and accounted for in dollars as an earmarked
                   asset of the borrowing Participant's Account.

         6.7       Error Correction

                   The Administrator may correct any errors or omissions in the
                   administration of the Plan by restoring any Participant's
                   Account balance with the amount that would be credited to the
                   Account had no error or omission been made. Funds necessary
                   for any such restoration shall be provided through payment
                   made by the Employer, or by the Trustee to the extent the
                   error or omission is attributable to actions or inactions of
                   the Trustee, or if the restoration involves an Account
                   holding amounts contributed by an Employer, the Administrator
                   may direct the Trustee to use amounts from the Forfeiture
                   Account.

                   accounting methods in performing their respective duties
                   during any Conversion Period. This includes, but is not
                   limited to, the method for allocating net investment gains or
                   losses and the extent, if any, to which contributions
                   received by and distributions paid from the Trust during this
                   period share in such allocation.

         6.10      Accounts for Alternate Payees

                   A separate Account shall be established for an Alternate
                   Payee entitled to any portion of a Participant's Account
                   under a QDRO as of the date and in accordance with the
                   directions specified in the QDRO. In addition, a separate
                   Account may be established during the period of time the
                   Administrator, a court of competent jurisdiction or other
                   appropriate person is determining whether a domestic
                   relations order qualifies as a QDRO. Such a separate Account
                   shall be valued and accounted for in the same manner as any
                   other Account.

                   (a)      Distributions Pursuant to QDROs. If a QDRO so
                            provides, the portion of a Participant's Account
                            payable to an Alternate Payee may be distributed, in
                            a form as permissible under Section 11 and Code
                            section 414(p), to the Alternate Payee at the time
                            specified in the QDRO, regardless of whether the
                            Participant is entitled to a distribution from the
                            Plan at such time. The Alternate Payee shall be
                            provided the notice prescribed by Code section
                            402(f).

                   (b)      Participant Loans. Except to the extent required by
                            law, an alternate payee, on whose behalf a separate
                            Account has been established, shall not be entitled
                            to borrow from such Account. If a QDRO specifies
                            that the alternate payee is entitled to any portion
                            of the Account of a Participant who has an
                            outstanding loan balance, all outstanding loans

                            may direct the investment of such Account in the
                            same manner as if he or she were a Participant.

         7.1       Investment Funds

                   Except for Participants' Sweep and Loan Accounts, the Trust
                   shall be maintained in various Investment Funds. The
                   Administrator shall select the Investment Funds offered to
                   Participants and may change the number or composition of the
                   Investment Funds, subject to the terms and conditions agreed
                   to with the Trustee. As of the Effective Date, a list of the
                   Investment Funds offered under the Plan is set forth in
                   Appendix A, and may be changed from time to time by the
                   Administrator, in writing, and as agreed to by the Trustee,
                   without the necessity of amending the Plan and Trust.

                   Each Participant shall direct the investment of all of his or
                   her Accounts except for his or her Profit Sharing
                   Post-09/30/96 Account which shall be entirely invested in the
                   Investment Fund specified by the Administrator, which
                   Investment Fund as of the Effective Date is set forth in

                   may direct the investment of the balance in his or her Profit
                   Sharing Post-09/30/96 Account. Future amounts allocated to
                   his or her Profit Sharing Post-09/30/96 Account shall
                   continue to be entirely invested in the Investment Fund
                   specified by the Administrator, until otherwise directed by
                   the Participant.

                   A Participant shall make his or her investment election in
                   any combination of one or any number of the Investment Funds
                   offered in accordance with the procedures established by the
                   Administrator and Trustee. However, during any Conversion
                   Period, Trust assets may be held in any investment vehicle
                   permitted by the Plan, as directed by the Administrator,
                   irrespective of Participant investment elections.

                   The Administrator may set a maximum percentage of the total
                   election that a Participant may direct into any specific
                   Investment Fund, which maximum, if any, as of the Effective
                   Date is set forth in Appendix A, and may be changed from time
                   to time by the Administrator, in writing, without the
                   necessity of amending the Plan and Trust.

         7.3       Responsibility for Investment Choice

                   Each Participant shall be solely responsible for the
                   selection of his or her Investment Fund choices. No fiduciary
                   with respect to the Plan is empowered to advise a Participant
                   as to the manner in which his or her Accounts are to be
                   invested, and the fact that an Investment Fund is offered
                   shall not be construed to be a recommendation for investment.

                   is not yet held in an Investment Fund and for which no valid

                   Administrator.

                            D = amount previously distributed

                            borrow, including the outstanding balance of

                            $50,000 maximum is reduced by the Participant's
                            highest outstanding loan balance during the 12 month
                            period ending on the day before the Sweep Date as of
                            which the loan is made. For purposes of this

                            Companies shall be treated as though they are part
                            of the Plan to the extent it would decrease the
                            maximum loan amount.

         9.6       Maximum Number of Loans

                   A Participant may have only one loan outstanding at any given
time.

         9.7       Source and Timing of Loan Funding

                   A loan to a Participant shall be made solely from the assets
                   of his or her own Account. The available assets shall be
                   determined first by Account type and then within each Account
                   used for funding a loan, amounts shall first be taken from
                   the Sweep Account and then taken by Investment Fund in direct
                   proportion to the market value of the Participant's interest
                   in each Investment Fund as of the Trade Date on which the
                   loan is processed.

                   The loan shall be funded on the Settlement Date following the
                   Trade Date as of which the loan is processed. The Trustee
                   shall make payment to the Participant as soon thereafter as
                   administratively feasible.

         9.8       Interest Rate

                   The interest rate charged on Participant loans shall be a
                   fixed reasonable rate of interest, determined from time to
                   time by the Administrator, which provides the Plan with a
                   return commensurate with the prevailing interest rate charged
                   by persons in the business of lending money for loans which
                   would be made under similar circumstances. As of the
                   Effective Date, the interest rate is determined as set forth
                   in Appendix C, and may be changed from time to time by the
                   Administrator, in writing, without the necessity of amending
                   the Plan and Trust.

         9.9       Loan Payment

                   Substantially level amortization shall be required of each
                   loan with payments made at least monthly, generally through
                   payroll deduction. Loans may be prepaid in full or in part at
                   any time. The Participant may choose the loan repayment
                   period, not to exceed 5 years.

         9.10      Loan Payment Hierarchy

                   Loan principal payments shall be credited to the
                   Participant's Accounts in the inverse of the order used to
                   fund the loan. Loan interest shall be credited to the
                   Participant's Accounts in direct proportion to the principal
                   payment. Loan payments are credited to the Investment Funds
                   based upon the Participant's current investment election for
                   new Contributions.

         9.11      Repayment Suspension

                   The Administrator may agree to a suspension of loan payments
                   for up to 3 months for a Participant who is on a Leave of
                   Absence without pay. During the suspension period interest
                   shall continue to accrue on the outstanding loan balance. At
                   the expiration of the suspension period all outstanding loan
                   payments and accrued interest thereon shall be due unless
                   otherwise agreed upon by the Administrator.

         9.12      Loan Default

                   A loan is treated as a default if scheduled loan payments are
                   more than 90 days late. A Participant shall then have 30 days
                   from the time he or she receives written notice of the
                   default and a demand for past due amounts to cure the default
                   before it becomes final.

                   In the event of default, the Administrator may direct the
                   Trustee to report the outstanding principal balance of the
                   loan and accrued interest thereon as a taxable distribution.
                   As soon as a Plan withdrawal or distribution to such
                   Participant would otherwise be permitted, the Administrator
                   may instruct the Trustee to execute upon its security
                   interest in the Participant's Account by distributing the
                   note to the Participant.

         9.13      Call Feature

                   The Administrator shall have the right to call any
                   Participant loan once a Participant's employment with all
                   Related Companies has terminated or if the Plan is
                   terminated.

10       IN-SERVICE WITHDRAWALS

         10.1      In-Service Withdrawals Permitted

                   In-service withdrawals to a Participant who is an Employee
                   are permitted pursuant to the terms and conditions set forth
                   in this Section and as required by law pursuant to the terms
                   and conditions set forth in Section 11.

         10.2      In-Service Withdrawal Application and Notice

                   A Participant shall apply for any in-service withdrawal in
                   such manner and with such advance notice as prescribed by the
                   Administrator. The Participant shall be provided the notice
                   prescribed by Code section 402(f).

                   Code sections 401(a)(11) and 417 do not apply to in-service
                   withdrawals under the Plan as described in this Section. An
                   in-service withdrawal may therefore commence less than 30
                   days after the aforementioned notice is provided, if:

                   (a)      the Participant is clearly informed that he or she
                            has the right to a period of at least 30 days after
                            receipt of such notice to consider his or her option
                            to elect or not elect a Direct Rollover for all or a
                            portion, if any, of his or her in-service withdrawal
                            which shall constitute an Eligible Rollover
                            Distribution; and

                   (b)      the Participant after receiving such notice,
                            affirmatively elects a Direct Rollover for all or a
                            portion, if any, of his or her in-service withdrawal
                            which shall constitute an Eligible Rollover
                            Distribution or alternatively elects to have all or
                            a portion made payable directly to him or her,
                            thereby not electing a Direct Rollover for all or a
                            portion thereof.

         10.3      Spousal Consent

                   A Participant is required to obtain Spousal Consent in order
                   to receive an inservice withdrawal under the Plan.

         10.4      In-Service Withdrawal Approval

                   The Administrator, or the Trustee, if otherwise authorized by
                   the Administrator and agreed to by the Trustee, is
                   responsible for determining that an in-service withdrawal
                   request conforms to the requirements described in this
                   Section and granting such request.

         10.5     Minimum Amount, Payment Form and Medium

                  The minimum amount for any type of in-service withdrawal is
                  $500.

<PAGE>   33
                   The form of payment for an in-service withdrawal shall be a
                   single lump sum and payment shall be made in cash. With
                   regard to the portion of an in-service withdrawal
                   representing an Eligible Rollover Distribution, a Participant
                   may elect a Direct Rollover for all or a portion of such
                   amount.

         10.6      Source and Timing of In-Service Withdrawal Funding

                   An in-service withdrawal to a Participant shall be made
                   solely from the assets of his or her own Account and shall be
                   based on the Account values as of the Trade Date the
                   in-service withdrawal is processed. The available assets
                   shall be determined first by Account type and then within
                   each Account used for funding an in-service withdrawal,
                   amounts shall first be taken from the Sweep Account and then
                   taken by Investment Fund in direct proportion to the market
                   value of the Participant's interest in each Investment Fund
                   (which excludes his or her Loan Account balance) as of the
                   Trade Date on which the in-service withdrawal is processed.

                   The in-service withdrawal shall be funded on the Settlement
                   Date following the Trade Date as of which the in-service
                   withdrawal is processed. The Trustee shall make payment as
                   soon thereafter as administratively feasible.

         10.7      Hardship Withdrawals

                   (a)      Requirements. A Participant who is an Employee may
                            request the withdrawal of up to the amount necessary

                            taxes or penalties reasonably anticipated to result

                           January 1, 1994 or accrued as of such date with
                           regard to Profit Sharing Contributions for the Plan
                           Year ending December 31, 1993, plus earnings
                           subsequently credited thereon.

                  (b)      Account Sources and Funding Order. The withdrawal
                           amount shall come from the Participant's fully vested
                           Prior Profit Sharing Account.

                  (c)      Permitted Frequency. There is no restriction on the
                           number of Prior Profit Sharing Account withdrawals
                           permitted to a Participant.

                  (d)      Suspension from Further Contributions. A Prior Profit
                           Sharing Account withdrawal shall not affect a
                           Participant's ability to make or be eligible to
                           receive further Contributions.

11       DISTRIBUTIONS ONCE EMPLOYMENT ENDS OR AS REQUIRED BY LAW

         11.1      Benefit Information, Notices and Election

                   A Participant, or his or her Beneficiary in the case of his
                   or her death, shall be provided with information regarding
                   all optional times and forms of distribution available, to
                   include the notices prescribed by Code sections 402(f) and
                   411(a)(11). Subject to the other requirements of this
                   Section, a Participant, or his or her Beneficiary in the case
                   of his or her death, may elect, in such manner and with such
                   advance notice as prescribed by the Administrator, to have
                   his or her vested Account balance paid to him or her
                   beginning upon any Settlement Date following the
                   Participant's termination of employment with all Related
                   Companies or, if earlier, at the time required by law as set
                   forth in Section 11.7.

                   A distribution may commence less than 30 days, but more than
                   7 days if such distribution is one to which Code sections
                   401(a)(11) and 417 apply, after the aforementioned notices
                   are provided, if:

                   (a)      the Participant is clearly informed that he or she
                            has the right to a period of at least 30 days after
                            receipt of such notices to consider the decision as
                            to whether to elect a distribution and if so to
                            elect a particular form of distribution and to elect
                            or not elect a Direct Rollover for all or a portion,
                            if any, of his or her distribution which shall
                            constitute an Eligible Rollover Distribution;

                   (b)      the Participant after receiving such notices,
                            affirmatively elects a distribution and a Direct
                            Rollover for all or a portion, if any, of his or her
                            distribution which shall constitute an Eligible
                            Rollover Distribution or alternatively elects to
                            have all or a portion made payable directly to him
                            or her, thereby not electing a Direct Rollover for
                            all or a portion thereof; and

                   (c)      if such distribution is one to which Code sections
                            401(a)(11) and 417 apply, the Participant's election
                            includes Spousal Consent.

         11.2      Spousal Consent

                   A Participant is required to obtain Spousal Consent in order
                   to receive a distribution under the Plan, except with regard
                   to a distribution made to a Participant without his or her
                   consent.

         11.3      Payment Form and Medium

                   Except to the extent otherwise provided by Section 11.4, and
                   subject to the requirements of Section 11.12, if applicable,
                   a Participant may elect to be paid in any of these forms,
                   except that the forms described in (d) are only available to
                   a Participant who entered the Plan prior to January 1, 1994:

                                       31

<PAGE>   38
                   (a)      a single lump sum,

                   (b)      a portion paid in a lump sum, and the remainder paid
                            later,

                   (c)      periodic installments over a period not to exceed
                            the life expectancy of the Participant and his or
                            her Beneficiary, or

                   (d)      for a single Participant, a single life annuity and
                            for a married Participant, a joint and 50% survivor
                            annuity with his or her spouse as the joint
                            annuitant.

                   With regard to a Participant who entered the Plan prior to
                   January 1, 1994 and except to the extent otherwise provided
                   by Section 11.4, unless the Participant elects otherwise as
                   provided for above, a married Participant's benefit shall be
                   paid in the form of an immediate qualified joint and 50%
                   survivor annuity with the Participant's spouse as the joint
                   annuitant and a single Participant's or surviving spouse
                   Beneficiary's benefit shall be paid in the form of a single
                   life annuity.

                   Any annuity option permitted shall be provided through the
                   purchase of a non-transferable single premium contract from
                   an insurance company which must conform to the terms of the
                   Plan and which shall be distributed to the Participant or
                   Beneficiary in complete satisfaction of the benefit due.

                   Distributions other than annuity contracts shall be made in
                   cash, except to the extent a distribution consists of a loan
                   call as described in Section 9. With regard to the portion of
                   a distribution representing an Eligible Rollover
                   Distribution, a Distributee may elect a Direct Rollover for
                   all or a portion of such amount.

         11.4      Distribution of Small Amounts

                   If after a Participant's employment with all Related
                   Companies ends, the Participant's vested Account balance is
                   $3,500 or less, and if at the time of any prior in-service
                   withdrawal or distribution the Participant's vested Account
                   balance did not exceed $3,500, the Participant's benefit
                   shall be paid as a single lump sum as soon as
                   administratively feasible in accordance with procedures
                   prescribed by the Administrator.

         11.5      Source and Timing of Distribution Funding

                   A distribution to a Participant shall be made solely from the
                   assets of his or her own Account and shall be based on the
                   Account values as of the Trade Date the distribution is
                   processed. The available assets shall be determined first by
                   Account type and then within each Account used for funding a
                   distribution, amounts shall first be taken from the Sweep
                   Account and then taken by Investment Fund in direct
                   proportion to the market value of the Participant's interest
                   in each Investment Fund as of the Trade Date on which the
                   distribution is processed.

<PAGE>   39
                   The distribution shall be funded on the Settlement Date
                   following the Trade Date as of which the distribution is
                   processed. The Trustee shall make payment as soon thereafter
                   as administratively feasible.

         11.6      Deemed Distribution

                   For purposes of Section 8, if at the time a Participant is
                   determined to be a Terminated Participant, his or her vested
                   Account balance attributable to Accounts subject to vesting
                   as described in Section 8, is zero, his or her vested Account
                   balance shall be deemed distributed as of the Settlement Date
                   following the Sweep Date on which he or she is determined to
                   be a Terminated Participant.

         11.7      Latest Commencement Permitted

                   In addition to any other Plan requirements and unless a
                   Participant elects otherwise, his or her benefit payments
                   shall begin not later than 60 days after the end of the Plan
                   Year in which he or she attains his or her Normal Retirement
                   Date or retires, whichever is later. However, if the amount
                   of the payment or the location of the Participant (after a
                   reasonable search) cannot be ascertained by that deadline,
                   payment shall be made no later than 60 days after the
                   earliest date on which such amount or location is ascertained
                   but in no event later than as described below. A
                   Participant's failure to elect in such manner as prescribed
                   by the Administrator to have his or her vested Account
                   balance paid to him or her, shall be deemed an election by
                   the Participant to defer his or her distribution.

                   Benefit payments shall begin by the April 1 immediately
                   following the end of the calendar year in which the
                   Participant attains age 70 1/2, whether or not he or she is
                   an Employee.

                   If benefit payments cannot begin at the time required because
                   the location of the Participant cannot be ascertained (after
                   a reasonable search), the Administrator may, at any time
                   thereafter, treat such person's Account as forfeited subject
                   to the provisions of Section 18.5.

         11.8      Payment Within Life Expectancy

                   The Participant's payment election must be consistent with
                   the requirement of Code section 401(a)(9) that all payments
                   are to be completed within a period not to exceed the lives
                   or the joint and last survivor life expectancy of the
                   Participant and his or her Beneficiary. The life expectancies
                   of a Participant and his or her Beneficiary, if such
                   Beneficiary is his or her spouse, may be recomputed annually.

<PAGE>   40
         11.9      Incidental Benefit Rule

                   The Participant's payment election must be consistent with
                   the requirement that, if the Participant's spouse is not his
                   or her sole primary Beneficiary, the minimum annual
                   distribution for each calendar year, beginning with the year
                   in which he or she attains age 70 1/2, shall not be less than
                   the quotient obtained by dividing (a) the Participant's
                   vested Account balance as of the last Trade Date of the
                   preceding year by (b) the applicable divisor as determined
                   under the incidental benefit requirements of Code section
                   401(a)(9).

         11.10     Payment to Beneficiary

                   Payment to a Beneficiary must either: (1) be completed by the
                   end of the calendar year that contains the fifth anniversary
                   of the Participant's death or (2) begin by the end of the
                   calendar year that contains the first anniversary of the
                   Participant's death and be completed within the period of the
                   Beneficiary's life or life expectancy, except that:

                   (a)      If the Participant dies after the April 1
                            immediately following the end of the calendar year
                            in which he or she attains age 70 1/2, payment to
                            his or her Beneficiary must be made at least as
                            rapidly as provided in the Participant's
                            distribution election;

                   (b)      If the surviving spouse is the Beneficiary, payments
                            need not begin until the end of the calendar year in
                            which the Participant would have attained age 70 1/2
                            and must be completed within the spouse's life or
                            life expectancy; and

                   (c)      If the Participant and the surviving spouse who is
                            the Beneficiary die (1) before the April 1
                            immediately following the end of the calendar year
                            in which the Participant would have attained age 70
                            1/2 and (2) before payments have begun to the
                            spouse, the spouse shall be treated as the
                            Participant in applying these rules.

         11.11     Beneficiary Designation

                   Each Participant may complete a beneficiary designation form
                   indicating the Beneficiary who is to receive the
                   Participant's remaining Plan interest at the time of his or
                   her death. The designation may be changed at any time.
                   However, a Participant's spouse shall be the sole primary
                   Beneficiary unless the designation includes Spousal Consent
                   for another Beneficiary. If no proper designation is in
                   effect at the time of a Participant's death or if the
                   Beneficiary does not survive the Participant, the Beneficiary
                   shall be, in the order listed, the:

                   (a)      Participant's surviving spouse,

                   (b)      Participant's children, in equal shares, (or if a
                            child does not survive the Participant, and that
                            child leaves issue, the issue shall be entitled to
                            that child's share, by right of representation) or

                   (c)      Participant's estate.

         11.12     QJSA and QPSA Information and Elections

                   The following definitions, information and election rules
                   shall apply to any Participant who entered the Plan prior to
                   January 1, 1994:

                   (a)      Annuity Starting Date. The first day of the first
                            period for which an amount is payable as an annuity,

                            of an annuity, the first day on which all events
                            have occurred which entitle the Participant to such
                            benefit. Such date shall be a date no earlier than
                            the expiration of the 30-day period that commences
                            the day after the information described in the QJSA
                            Information to a Participant paragraph below is
                            provided to the Participant, except that effective
                            January 1, 1996, "7-day period" shall be substituted
                            for the preceding reference to "30-day period".

                            meaning for a married Participant, a form of benefit

                            Participant's vested Account balance at the Annuity
                            Starting Date, payable to the Participant in monthly

                            such former Employee was an HCE when he separated
                            from service, or (2) such former Employee was an HCE
                            in service at any time after attaining age 55.

                            The determination of who is an HCE, including the
                            determinations of the number and identity of
                            Employees in the top-paid group, the top 100
                            Employees and the number of Employees treated as
                            officers shall be made in accordance with Code
                            section 414(q).

                   (j)      "HCE Group" and "NHCE Group". With respect to each
                            Employer and its Related Companies, the respective
                            group of HCEs and NHCEs who are eligible to have
                            amounts contributed on their behalf for the Plan
                            Year, including Employees who would be eligible but
                            for their election not to participate or to
                            contribute, or because their Pay is greater than
                            zero but does not exceed a stated minimum.

                            (1)      If the Related Companies maintain two or
                                     more plans which are subject to the ADP or
                                     ACP Test and are considered as one plan for
                                     purposes of Code sections 401(a)(4) or
                                     410(b), all such plans shall be aggregated
                                     and treated as one plan for purposes of
                                     meeting the ADP and ACP Tests, provided
                                     that the plans may only be aggregated if
                                     they have the same Plan Year.

                            (2)      If an HCE, who is one of the top 10 paid
                                     Employees or a more than 5% Owner, has any
                                     Family Members, the Deferrals,
                                     Contributions and Compensation of such HCE
                                     and his or her Family Members shall be
                                     combined and treated as a single HCE. Such
                                     amounts for all other Family Members shall
                                     be removed from the NHCE Group percentage
                                     calculation and be combined with the HCE's.

                            (3)      If an HCE is covered by more than one cash
                                     or deferred arrangement, or more than one
                                     arrangement permitting employee or matching
                                     contributions, maintained by the Related
                                     Companies, all such plans shall be
                                     aggregated and treated as one plan (other
                                     than those plans that may not be
                                     permissively aggregated) for purposes of
                                     calculating the separate percentage for the
                                     HCE which is used in the determination of
                                     the Average Percentage. For purposes of the
                                     preceding sentence, if such plans have
                                     different plan years, all such plans ending
                                     with or within the same calendar year shall
                                     be aggregated.

                   (k)      "Lookback Year". Pursuant to Code section 414(q),
                            the Company elects as the Lookback Year the current
                            calendar year (ending with the Plan Year).

                   (l)      "Multiple Use Test". The test described in Section
                            12.4 which a Plan must meet where the Alternative
                            Limitation (described in Section 12.2(b)) is used to
                            meet both the ADP and ACP Tests.

                   (m)      "NHCE" or "Non-Highly Compensated Employee". An
                            Employee who is not an HCE.

         12.2      ADP and ACP Tests

                   For each Plan Year, the ADP and ACP for the HCE Group must
                   meet either the Basic or Alternative Limitation when compared
                   to the respective ADP and ACP for the NHCE Group, defined as
                   follows:

                   (a)      Basic Limitation. The HCE Group Average Percentage
                            may not exceed 1.25 times the NHCE Group Average
                            Percentage.

                   (b)      Alternative Limitation. The HCE Group Average
                            Percentage is limited by reference to the NHCE Group
                            Average Percentage as follows:


        IF THE NHCE GROUP                        THEN THE MAXIMUM HCE
      AVERAGE PERCENTAGE IS:                 GROUP AVERAGE PERCENTAGE IS:

           Less than 2%                      2 times NHCE Group Average %
             2% to 8%                        NHCE Group Average % plus 2%
           More than 8%                     NA - Basic Limitation applies


         12.3      Correction of ADP and ACP Tests

                   If the ADP or ACP Tests are not met, the Administrator shall
                   determine, no later than the end of the next Plan Year, a
                   maximum percentage to be used in place of the calculated
                   percentage for all HCEs that would reduce the ADP and/or ACP
                   for the HCE group by a sufficient amount to meet the ADP and
                   ACP Tests. ADP and/or ACP corrections shall be made in
                   accordance with the leveling method as described below.

                   (a)      ADP Correction. The HCE with the highest Deferral
                            percentage shall have his or her Deferral percentage
                            reduced to the lesser of the extent required to meet
                            the ADP Test or to cause his or her Deferral
                            percentage to equal that of the HCE with the next
                            highest Deferral percentage. The process shall be
                            repeated until the ADP Test is met.

                            To the extent an HCE's Deferrals were determined to
                            be reduced as described in the paragraph above,
                            401(k) Contributions shall, by the end

                            of the next Plan Year, be refunded to the HCE in an
                            amount equal to the actual Deferrals minus the
                            product of the maximum percentage and the HCE's
                            Compensation, except that such amount to be refunded
                            shall be reduced by 401(k) Contributions previously
                            refunded because they exceeded the Contribution
                            Dollar Limit. The excess amounts shall first be
                            taken from unmatched 401(k) Contributions and then
                            from matched 401(k) Contributions. Any Spieker Match
                            Contributions attributable to refunded excess 401(k)
                            Contributions as described in this Section shall be
                            forfeited and used as described in Section 8.5.

                   (b)      ACP Correction. The HCE with the highest
                            Contribution percentage shall have his or her
                            Contribution percentage reduced to the lesser of the
                            extent required to meet the ACP Test or to cause his
                            or her Contribution percentage to equal that of the
                            HCE with the next highest Contribution percentage.
                            The process shall be repeated until the ACP Test is
                            met.

                            To the extent an HCE's Contributions were determined
                            to be reduced as described in the paragraph above,
                            Spieker Match Contributions shall, by the end of the
                            next Plan Year, be refunded to the HCE to the extent
                            vested, and forfeited and used as described in
                            Section 8.5 to the extent such amounts were not
                            vested, as of the end of the Plan Year being tested,
                            in an amount equal to the actual Contributions minus
                            the product of the maximum percentage and the HCE's
                            Compensation.

                   (c)      Investment Fund Sources. Once the amount of excess
                            Deferrals and/or Contributions is determined amounts
                            shall first be taken from the Sweep Account and then
                            taken by Investment Fund in direct proportion to the
                            market value of the Participant's interest in each
                            Investment Fund (which excludes his or her Loan
                            Account balance) as of the Trade Date on which the
                            correction is processed.

                   (d)      Family Member Correction. To the extent any
                            reduction is necessary with respect to an HCE and
                            his or her Family Members that have been combined
                            and treated for testing purposes as a single
                            Employee, the excess Deferrals and Contributions
                            from the ADP and/or ACP Test shall be prorated among
                            each such Participant in direct proportion to his or
                            her Deferrals or Contributions included in each
                            Test.

         12.4      Multiple Use Test

                   If the Alternative Limitation (defined in Section 12.2) is
                   used to meet both the ADP and ACP Tests, the ADP and ACP for
                   the HCE Group must also comply with the requirements of Code
                   section 401(m)(9). Such Code section requires that the sum of
                   the ADP and ACP for the HCE Group (as determined after any
                   corrections needed to meet the ADP and ACP Tests have been
                   made) not exceed the sum (which produces the most favorable
                   result) of:

<PAGE>   48
                   (a)      the Basic Limitation (defined in Section 12.2)
                            applied to either the ADP or ACP for the NHCE Group,
                            and

                   (b)      the Alternative Limitation applied to the other NHCE
                            Group percentage.

         12.5      Correction of Multiple Use Test

                   If the multiple use limit is exceeded, the Administrator
                   shall determine a maximum percentage to be used in place of
                   the calculated percentage for all HCEs that would reduce
                   either or both the ADP or ACP for the HCE Group by a
                   sufficient amount to meet the multiple use limit. Any excess
                   shall be handled in the same manner that the distribution of
                   excess Deferrals or Contributions are handled.

         12.6      Adjustment for Investment Gain or Loss

                   Any excess Deferrals or Contributions to be refunded to a
                   Participant or forfeited in accordance with Section 12.3 or
                   12.5 shall be adjusted for investment gain or loss. Refunds
                   or forfeitures shall not include investment gain or loss for
                   the period between the end of the applicable Plan Year and
                   the date of distribution.

         12.7      Testing Responsibilities and Required Records

                   The Administrator shall be responsible for ensuring that the
                   Plan meets the ADP Test, the ACP Test and the Multiple Use
                   Test, and that the Contribution Dollar Limit is not exceeded.
                   The Administrator shall maintain records which are sufficient
                   to demonstrate that the ADP Test, the ACP Test and the
                   Multiple Use Test, have been met for each Plan Year for at
                   least as long as the Employer's corresponding tax year is
                   open to audit.

         12.8      Separate Testing

                   (a)      Multiple Employers: The determination of HCEs,
                            NHCEs, and the performance of the ADP Test, the ACP
                            Test and the Multiple Use Test, and any corrective
                            action resulting therefrom, shall be conducted
                            separately with regard to the Employees of each
                            Employer (and its Related Companies) that is not a
                            Related Company with the other Employer(s).

                   (b)      Collective Bargaining Units: The performance of the
                            ADP Test, and if applicable, the ACP Test and the
                            Multiple Use Test, and any corrective action
                            resulting therefrom, shall be conducted separately
                            with regard to Employees who are eligible to
                            participate in the Plan as a result of a collective
                            bargaining agreement.

                   In addition, testing may be conducted separately, at the
                   discretion of the Administrator and to the extent permitted
                   under Treasury regulations, to any group of Employees for
                   whom separate testing is permissible.

                   The Plan Year shall be the Code section 415 limitation year.

         13.2      Maximum Annual Addition

                   The Annual Addition to a Participant's accounts under the
                   Plan and any other defined contribution plan maintained by
                   any Related Company for any Plan Year shall not exceed the
                   lesser of (1) 25% of his or her Taxable Income or (2) the
                   greater of $30,000 or one-quarter of the dollar limitation in
                   effect under Code section 415(b)(1)(A), except that effective
                   January 1, 1995, "(2) $30,000 (as adjusted for the cost of
                   living pursuant to Code section 415(d)" shall be substituted
                   for the preceding reference to "(2) the greater of $30,000 or
                   one-quarter of the dollar limitation in effect under Code
                   section 415(b)(1)(A)".

         13.3      Avoiding an Excess Annual Addition

                   If, at any time during a Plan Year, the allocation of any
                   additional Contributions would produce an excess Annual
                   Addition for such year, Contributions to be made for the
                   remainder of the Plan Year shall be limited to the amount
                   needed for each affected Participant to receive the maximum
                   Annual Addition.

         13.4      Correcting an Excess Annual Addition

                   Upon the discovery of an excess Annual Addition to a
                   Participant's Account (resulting from forfeitures,
                   allocations, reasonable error in determining Participant
                   compensation or the amount of elective contributions, or
                   other facts and circumstances acceptable to the Internal
                   Revenue Service) the excess amount (adjusted to reflect
                   investment gains) shall first be returned to the Participant
                   to the extent of his or her 401(k) Contributions (however to
                   the extent 401(k) Contributions were matched, the applicable
                   Spieker Match Contributions shall be forfeited in proportion
                   to the returned matched 401(k) Contributions) and the
                   remaining excess, if any, shall be forfeited by the
                   Participant and together used as described in Section 8.5.

         13.5     Correcting a Multiple Plan Excess

                  If a Participant, whose Account is credited with an excess
                  Annual Addition, received allocations to more than one defined
                  contribution plan, the excess shall be corrected by reducing
                  the Annual Addition to the Plan only after all possible
                  reductions have been made to the other defined contribution
                  plans.

         13.6     "Defined Benefit Fraction" Defined

                  The fraction, for any Plan Year, where the numerator is the
                  "projected annual benefit" and the denominator is the greater
                  of 125% of the "protected current accrued benefit" or the
                  normal limit which is the lesser of (1) 125% of the maximum
                  dollar limitation provided under Code section 415(b)(1)(A) for
                  the Plan Year or (2) 140% of the amount which may be taken
                  into account under Code section 415(b)(1)(B) for the Plan
                  Year, where a Participant's:

                  (a)      "projected annual benefit" is the annual benefit
                           provided by the Plan determined pursuant to Code
                           section 415(e)(2)(A), and

                  (b)      "protected current accrued benefit" in a defined
                           benefit plan in existence (1) on July 1, 1982, shall
                           be the accrued annual benefit provided for under
                           Public Law 97-248, section 235(g)(4), as amended, or
                           (2) on May 6, 1986, shall be the accrued annual
                           benefit provided for under Public Law 99-514, section
                           1106(i)(3).

         13.7     "Defined Contribution Fraction" Defined

                   The fraction where the numerator is the sum of the
                   Participant's Annual Addition for each Plan Year to date and
                   the denominator is the sum of the "annual amounts" for each
                   year in which the Participant has performed service with a
                   Related Company. The "annual amount" for any Plan Year is the
                   lesser of (1) 125% of the Code section 415(c)(1)(A) dollar
                   limitation (determined without regard to subsection (c)(6))
                   in effect for the Plan Year and (2) 140% of the Code section
                   415(c)(1)(B) amount in effect for the Plan Year, where:

                  (a)      each Annual Addition is determined pursuant to the
                           Code section 415(c) rules in effect for such Plan
                           Year, and

                  (b)      the numerator is adjusted pursuant to Public Law
                           97-248, section 235(g)(3), as amended, or Public Law
                           99-514, section 1106(i)(4).

         13.8      Combined Plan Limits and Correction

                   If a Participant has also participated in a defined benefit
                   plan maintained by a Related Company, the sum of the Defined
                   Benefit Fraction and the Defined Contribution Fraction for
                   any Plan Year may not exceed 1.0. If the combined fraction
                   exceeds 1.0 for any Plan Year, the Participant's benefit
                   under any defined benefit plan (to the extent it has not been
                   distributed or used to purchase an annuity contract) shall be
                   limited so that the combined fraction does not exceed 1.0
                   before any defined contribution limits shall be enforced.

                           benefit plan which automatically provides a benefit
                           which satisfies the Code section 416(c)(1) minimum
                           benefit requirements, including the adjustment

                           If the Plan is part of an aggregation group in which
                           a Key Employee is receiving a benefit and no minimum

                           specified in the preceding paragraph. In addition,
                           the Employer may offset a defined benefit minimum by
                           contributions (other than contributions made by an
                           Employer in accordance with a Participant's salary
                           deferral election or contributions made by an
                           Employer based upon the amount contributed by a
                           Participant) made to the Plan.

         14.3      Adjustment to Combined Limits for Different Plans

                   For each Plan Year in which the Plan is Top Heavy, 100% shall

                   permitted under ERISA section 405, no fiduciary shall be
                   liable for a breach by another fiduciary.

         15.2      Fiduciary Standards

                   Each fiduciary shall:

                   (a)     discharge his or her duties in accordance with the
                           Plan and Trust to the extent they are consistent with
                           ERISA;

                   (b)     use that degree of care, skill, prudence and
                           diligence that a prudent person acting in a like
                           capacity and familiar with such matters would use in
                           the conduct of an enterprise of a like character and
                           with like aims;

                   (c)     act with the exclusive purpose of providing benefits
                           to Participants and their Beneficiaries, and
                           defraying reasonable expenses of administering the
                           Plan;

                   (d)     diversify Plan investments, to the extent such
                           fiduciary is responsible for directing the
                           investment of Plan assets, so as to minimize the
                           risk of large losses, unless under the circumstances
                           it is clearly prudent not to do so; and

                   (e)     treat similarly situated Participants and
                           Beneficiaries in a uniform and nondiscriminatory
                           manner.

         15.3      Company is ERISA Plan Administrator

                   The Company is the plan administrator, within the meaning of
                   ERISA section 3(16), which is responsible for compliance with
                   all reporting and disclosure requirements, except those that
                   are explicitly the responsibility of the Trustee under
                   applicable law. The Administrator and/or Committee shall have
                   any necessary authority to carry out such functions through
                   the actions of the Administrator, duly appointed officers of
                   the Company, and/or the Committee.

                  or not such powers are specifically set forth in the Plan and
                  Trust. Actions taken in good faith by the Administrator shall
                  be conclusive and binding on all interested parties, and shall
                  be given the maximum possible deference allowed by law. In

                           under ERISA section 104(b)(1)), as well as informing
                           each Participant of any material modification to the
                           Plan in a timely manner;

                  (c)      make a copy of the following documents available to
                           Participants during normal work hours: the Plan and
                           Trust (including subsequent amendments), all annual
                           and interim reports of the Trustee related to the

                           any Beneficiary's right to receive the deceased
                           Participant's interest based upon such proof and
                           evidence as it deems necessary;

                  (e)      establish and review at least annually a funding
                           policy bearing in mind both the short-run and
                           long-run needs and goals of the Plan and to the
                           extent Participants may direct their own investments,
                           the funding policy shall focus on which Investment
                           Funds are available for Participants to use; and

                  (f)      adjudicate claims pursuant to the claims procedure
                           described in Section 18.

                  record keepers, investment counsel and administrative
                  assistants) as it considers necessary to assist it in the
                  performance of its duties. The Administrator shall also comply
                  with the bonding requirements of ERISA section 412.

         15.6     Delegation of Administrator Duties

                  The Company, as Administrator of the Plan, has appointed a
                  Committee to administer the Plan on its behalf. The Company
                  shall provide the Trustee with the names and specimen
                  signatures of any persons authorized to serve as Committee
                  members and act as or on its behalf. Any Committee member
                  appointed by the Company shall serve at the pleasure of the
                  Company, but may resign by written notice to the Company.
                  Committee members shall serve without compensation from the
                  Plan for such services. Except to the extent that the Company
                  otherwise provides, any delegation of duties to a Committee
                  shall carry with it the full discretionary authority of the
                  Administrator to complete such duties.

         15.7     Committee Operating Rules

                  (a)      Actions of Majority. Any act delegated by the Company
                           to the Committee may be done by a majority of its
                           members. The majority may be expressed by a vote at a
                           meeting or in writing without a meeting, and a
                           majority action shall be equivalent to an action of
                           all Committee members.

                  (b)      Meetings. The Committee shall hold meetings upon such
                           notice, place and times as it determines necessary to
                           conduct its functions properly.

                  (c)      Reliance by Trustee. The Committee may authorize one
                           or more of its members to execute documents on its
                           behalf and may authorize one or more of its members
                           or other individuals who are not members to give
                           written direction to the Trustee in the performance
                           of its duties. The Committee shall provide such
                           authorization in writing to the Trustee with the name
                           and specimen signatures of any person authorized to
                           act on its behalf. The Trustee shall accept such
                           direction and rely upon it until notified in writing
                           that the Committee has revoked the authorization to
                           give such direction. The Trustee shall not be deemed
                           to be on notice of any change in the membership of
                           the Committee, parties authorized to direct the
                           Trustee in the performance of its duties, or the
                           duties delegated to and by the Committee until
                           notified in writing.

                  All Plan assets shall be held by the Trustee in trust, in
                  accordance with those provisions of the Plan and Trust which
                  relate to the Trustee, for use in providing Plan benefits and
                  paying Plan fees and expenses not paid directly by the
                  Employer. Plan benefits shall be drawn solely from the Trust
                  and paid by the Trustee as directed by the Administrator.

                  Funds. The number and composition of Investment Funds may be
                  changed from time to time, without the necessity of amending
                  the Plan and Trust. The Trustee may establish reasonable
                  limits on the number of Investment Funds as well as the
                  acceptable assets for any such Investment Fund. Each of the
                  Investment Funds may be comprised of any of the following:

                  (a)      shares of a registered investment company, whether or

                           company;

                  (b)      collective investment funds maintained by the
                           Trustee, or any other fiduciary to the Plan, which
                           are available for investment by trusts which are
                           qualified under Code sections 401(a) and 501(a);

                  (c)      individual equity and fixed income securities which

                  Any Investment Fund assets invested in a collective investment
                  fund, shall be subject to all the provisions of the
                  instruments establishing and governing such fund. These
                  instruments, including any subsequent amendments, are
                  incorporated herein by reference.

         16.3     Authority to Hold Cash

                  The Trustee shall have the authority to cause the investment
                  manager of each Investment Fund to maintain sufficient deposit
                  or money market type assets in each Investment Fund to handle
                  the Fund's liquidity and disbursement needs. Each
                  Participant's and Beneficiary's Sweep Account, which is used
                  to hold assets pending investment or disbursement, shall
                  consist of interest bearing deposits of the Trustee.

         16.4     Trustee to Act Upon Instructions

                  The Trustee shall carry out instructions to invest assets in
                  the Investment Funds as soon as practicable after such
                  instructions are received from the Administrator,
                  Participants, or Beneficiaries. Such instructions shall remain
                  in effect until changed by the Administrator, Participants or
                  Beneficiaries.

                  behalf of the Plan in a registered investment company.
                  Notwithstanding, the authority to vote proxies and exercise
                  shareholder rights related to such shares held in a Custom
                  Fund is vested as provided otherwise in Section 16.

         16.6     Custom Fund Investment Management

                  The Administrator may designate, with the consent of the
                  Trustee, an investment manager for any Investment Fund
                  established by the Trustee solely for Participants of the Plan
                  (a "Custom Fund"). The investment manager may be the
                  Administrator, Trustee or an investment manager pursuant to
                  ERISA section 3(38). The Administrator shall advise the
                  Trustee in writing of the appointment of an investment manager
                  and shall cause the investment manager to acknowledge to the
                  Trustee in writing that the investment manager is a fiduciary
                  to the Plan.

                  A Custom Fund shall be subject to the following:

                  (a)      Guidelines. Written guidelines, acceptable to the
                           Trustee, shall be established for a Custom Fund. If a
                           Custom Fund consists solely of collective investment
                           funds or shares of a registered investment company
                           (and sufficient deposit or money market type assets
                           to handle the Fund's liquidity and disbursement
                           needs), its underlying instruments shall constitute
                           the guidelines.

                  (b)      Authority of Investment Manager. The investment
                           manager of a Custom Fund shall have the authority to
                           vote or execute proxies, exercise shareholder rights,
                           manage, acquire, and dispose of Trust

                           assets. Notwithstanding, the authority to vote
                           proxies and exercise shareholder rights related to
                           shares of Company Stock held in a Custom Fund is
                           vested as provided otherwise in Section 16.

                  (c)      Custody and Trade Settlement. Unless otherwise agreed
                           to by the Trustee, the Trustee shall maintain custody
                           of all Custom Fund assets and be responsible for the
                           settlement of all Custom Fund trades. For purposes of
                           this section, shares of a collective investment fund,
                           shares of a registered investment company and
                           guaranteed investment contracts issued by a bank or
                           insurance company, shall be regarded as the Custom
                           Fund assets instead of the underlying assets of such
                           instruments.

                  (d)      Limited Liability of Co-Fiduciaries. Neither the
                           Administrator nor the Trustee shall be obligated to
                           invest or otherwise manage any Custom Fund assets for
                           which the Trustee or Administrator is not the
                           investment manager nor shall the Administrator or
                           Trustee be liable for acts or omissions with regard
                           to the investment of such assets except to the extent
                           required by ERISA.

         16.7     Authority to Segregate Assets

                  The Company may direct the Trustee to split an Investment Fund
                  into two or more funds in the event any assets in the Fund are
                  illiquid or the value is not readily determinable. In the
                  event of such segregation, the Company shall give instructions
                  to the Trustee on what value to use for the split-off assets,
                  and the Trustee shall not be responsible for confirming such
                  value.

         16.8     Investment in Company Stock

                  If the Company provides for a Company Stock Fund, the Fund
                  shall be comprised of Company Stock and sufficient deposit or
                  money market type assets to handle the Fund's liquidity and
                  disbursement needs. The Fund may be as large as necessary to
                  comply with Participants' and Beneficiaries' investment
                  elections as well the total investment of Participants' and
                  Beneficiaries' Profit Sharing Post-09/30/96 Accounts.

         16.9     Participants Have Right to Vote and Tender Company Stock

                  Each Participant or Beneficiary shall be entitled to instruct
                  the Trustee as to the voting or tendering of any full or
                  partial shares of Company Stock held on his or her behalf in
                  the Company Stock Fund. Prior to such voting or tendering of
                  Company Stock, each Participant or Beneficiary shall receive a
                  copy of the proxy solicitation or other material relating to
                  such vote or tender decision and a form for the Participant or
                  Beneficiary to complete which confidentially instructs the
                  Trustee to vote or tender such shares in the manner indicated
                  by the Participant or Beneficiary. Upon receipt of such
                  instructions, the Trustee shall act with respect to such
                  shares as instructed.

                  With regard to shares for which the Trustee receives no voting
                  or tendering instructions from Participants or Beneficiaries,
                  the Administrator shall instruct the Trustee with respect to
                  how to vote or tender such shares and the Trustee shall act
                  with respect to such shares as instructed.

         16.10    Registration and Disclosure for Company Stock

                  requirements of the Securities Act of 1933, as amended, the
                  California Corporate Securities Law of 1968, as amended, and
                  any other applicable blue sky law. The Administrator shall
                  also specify what restrictive legend or transfer restriction,
                  if any, is required to be set forth on the certificates for
                  the securities and the procedure to be followed by the Trustee
                  to effectuate a resale of such securities.

                   Trust assets and, not in limitation but in amplification of

         17.4     Tax Withholding and Payment

                  (a)      Withholding. The Trustee shall calculate and withhold
                           federal (and, if applicable, state) income taxes with
                           regard to any Eligible Rollover Distribution that is
                           not paid as a Direct Rollover in accordance with the
                           Participant's withholding election or as required by
                           law if no election is made or the election is less
                           than the amount required by law. With regard to any
                           taxable distribution that is not an Eligible Rollover
                           Distribution, the Trustee shall calculate and
                           withhold federal (and, if applicable, state) income
                           taxes in accordance with the Participant's
                           withholding election or as required by law if no
                           election is made.

                  (b)      Taxes Due From Investment Funds. The Trustee shall
                           pay from the Investment Fund any taxes or assessments
                           imposed by any taxing or governmental authority on
                           such Fund or its income, including related interest
                           and penalties.

         17.5     Trust Accounting

                  (a)      Annual Report. Within 60 days (or other reasonable
                           period) following the close of the Plan Year, the
                           Trustee shall provide the Administrator with an
                           annual accounting of Trust assets and information to
                           assist the Administrator in meeting ERISA's annual
                           reporting and audit requirements.

                  (b)      Periodic Reports. The Trustee shall maintain records
                           and provide sufficient reporting to allow the
                           Administrator to properly monitor the Trust's assets
                           and activity.

                  (c)      Administrator Approval. Approval of any Trustee
                           accounting shall automatically occur 90 days after
                           such accounting has been received by the
                           Administrator, unless the Administrator files a
                           written objection with the Trustee within such time
                           period. Such approval shall be final as to all
                           matters and transactions stated or shown therein and
                           binding upon the Administrator.

         17.6     Valuation of Certain Assets

                  If the Trustee determines the Trust holds any asset which is
                  not readily tradeable and listed on a national securities
                  exchange registered under the Securities Exchange Act of 1934,
                  as amended, the Trustee may engage a qualified independent
                  appraiser to determine the fair market value of such property,
                  and the appraisal fees shall be paid from the Investment Fund
                  containing the asset.

         17.7      Legal Counsel

                   The Trustee may consult with legal counsel of its choice,
                   including counsel for the Employer or counsel of the Trustee,
                   upon any question or matter arising under the Plan and Trust.
                   When relied upon by the Trustee, the opinion of such counsel
                   shall be evidence that the Trustee has acted in good faith.

         17.8      Fees and Expenses

                   The Trustee's fees for its services as Trustee shall be such
                   as may be mutually agreed upon by the Company and the
                   Trustee. Trustee fees and all reasonable expenses of counsel
                   and advisors retained by the Trustee shall be paid in
                   accordance with Section 6.

         17.9      Trustee Duties and Limitations

                   The Trustee's duties, unless otherwise agreed to by the
                   Trustee, shall be confined to construing the terms of the
                   Plan and Trust as they relate to the Trustee, receiving funds
                   on behalf of and making payments from the Trust, safeguarding
                   and valuing Trust assets, investing and reinvesting Trust
                   assets in the Investment Funds as directed by the
                   Administrator, Participants or Beneficiaries and those duties
                   as described in this Section 17.

                   The Trustee shall have no duty or authority to ascertain
                   whether Contributions are in compliance with the Plan, to
                   enforce collection or to compute or verify the accuracy or
                   adequacy of any amount to be paid to it by the Employer. The
                   Trustee shall not be liable for the proper application of any
                   part of the Trust with respect to any disbursement made at
                   the direction of the Administrator.

18       RIGHTS, PROTECTION, CONSTRUCTION AND JURISDICTION

         18.1     Plan Does Not Affect Employment Rights

                  The Plan does not provide any employment rights to any
                  Employee. The Employer expressly reserves the right to
                  discharge an Employee at any time, with or without cause,
                  without regard to the effect such discharge would have upon
                  the Employee's interest in the Plan.

         18.2     Limited Return of Contributions

                  Except as provided in this paragraph, (1) Plan assets shall
                  not revert to the Employer nor be diverted for any purpose
                  other than the exclusive benefit of Participants or their
                  Beneficiaries; and (2) a Participant's vested interest shall
                  not be subject to divestment. As provided in ERISA section
                  403(c)(2), the actual amount of a Contribution made by the
                  Employer (or the current value of the Contribution if a net
                  loss has occurred) may revert to the Employer if:

                  (a)      such Contribution is made by reason of a mistake of
                           fact;

                  (b)      initial qualification of the Plan under Code section
                           401(a) is not received and a request for such
                           qualification is made within the time prescribed
                           under Code section 401(b) (the existence of and
                           Contributions under the Plan are hereby conditioned
                           upon such qualification); or

                  (c)      such Contribution is not deductible under Code
                           section 404 (such Contributions are hereby
                           conditioned upon such deductibility) in the taxable
                           year of the Employer for which the Contribution is
                           made.

                   The reversion to the Employer must be made (if at all) within
                   one year of the mistaken payment of the Contribution, the
                   date of denial of qualification, or the date of disallowance
                   of deduction, as the case may be. A Participant shall have no
                   rights under the Plan with respect to any such reversion.

         18.3     Assignment and Alienation

                  As provided by Code section 401(a)(13) and to the extent not
                  otherwise required by law, no benefit provided by the Plan may
                  be anticipated, assigned or alienated, except:

                  (a)      to create, assign or recognize a right to any benefit
                           with respect to a Participant pursuant to a QDRO, or

                  (b)      to use a Participant's vested Account balance as
                           security for a loan from the Plan which is permitted
                           pursuant to Code section 4975.

         18.4      Facility of Payment

                   If a Plan benefit is due to be paid to a minor or if the
                   Administrator reasonably believes that any payee is legally
                   incapable of giving a valid receipt and discharge for any
                   payment due him or her, the Administrator shall have the
                   payment of the benefit, or any part thereof, made to the
                   person (or persons or institution) whom it reasonably
                   believes is caring for or supporting the payee, unless it has
                   received due notice of claim therefor from a duly appointed
                   guardian or conservator of the payee. Any payment shall to
                   the extent thereof, be a complete discharge of any liability
                   under the Plan to the payee.

         18.5      Reallocation of Lost Participant's Accounts

                   If the Administrator cannot locate a person entitled to
                   payment of a Plan benefit after a reasonable search, the
                   Administrator may at any time thereafter treat such person's
                   Account as forfeited and use such amount as described in
                   Section 8.5. If such person subsequently presents the
                   Administrator with a valid claim for the benefit, such person
                   shall be paid the amount treated as forfeited, plus the
                   interest that would have been earned in the Sweep Account to
                   the date of determination. The Administrator shall pay the
                   amount through an additional amount contributed by the
                   Employer or direct the Trustee to pay the amount from the
                   Forfeiture Account.

         18.6      Claims Procedure

                   (a)      Right to Make Claim. An interested party who
                            disagrees with the Administrator's determination of
                            his or her right to Plan benefits must submit a
                            written claim and exhaust this claim procedure
                            before legal recourse of any type is sought. The
                            claim must include the important issues the
                            interested party believes support the claim. The
                            Administrator, pursuant to the authority provided in
                            the Plan, shall either approve or deny the claim.

                   (b)      Process for Denying a Claim. The Administrator's
                            partial or complete denial of an initial claim must
                            include an understandable, written response covering
                            (1) the specific reasons why the claim is being
                            denied (with reference to the pertinent Plan
                            provisions) and (2) the steps necessary to perfect
                            the claim and obtain a final review.

                   (c)      Appeal of Denial and Final Review. The interested
                            party may make a written appeal of the
                            Administrator's initial decision, and the
                            Administrator shall respond in the same manner and
                            form as prescribed for denying a claim initially.

                  (d)      Time Frame. The initial claim, its review, appeal and
                           final review shall be made in a timely fashion,
                           subject to the following time table:

                           However, the Administrator may take up to twice the
                           maximum response time for its initial and final
                           review if it provides an explanation within the
                           normal period of why an extension is needed and when
                           its decision shall be forthcoming.

         18.7      Construction

                   Headings are included for reading convenience. The text shall
                   control if any ambiguity or inconsistency exists between the
                   headings and the text. The singular and plural shall be
                   interchanged wherever appropriate. References to Participant
                   shall include Alternate Payee and/or Beneficiary when
                   appropriate and even if not otherwise already expressly
                   stated.

         18.8      Jurisdiction and Severability

                   The Plan and Trust shall be construed, regulated and
                   administered under ERISA and other applicable federal laws
                   and, where not otherwise preempted, by the laws of the State
                   of California. If any provision of the Plan and Trust shall
                   become invalid or unenforceable, that fact shall not affect
                   the validity or enforceability of any other provision of the
                   Plan and Trust. All provisions of the Plan and Trust shall be
                   so construed as to render them valid and enforceable in
                   accordance with their intent.

         18.9      Indemnification by Employer

                   The Employers hereby agree to indemnify all Plan fiduciaries
                   against any and all liabilities resulting from any action or
                   inaction, (including a Plan termination in which the Company
                   fails to apply for a favorable determination from the
                   Internal Revenue Service with respect to the qualification of
                   the Plan upon its termination), in relation to the Plan or
                   Trust (1) including (without limitation) expenses reasonably
                   incurred in the defense of any claim relating to the Plan or
                   its assets, and amounts paid in any settlement relating to
                   the Plan or its assets, but (2) excluding liability resulting
                   from actions or inactions made in bad faith, or resulting
                   from the negligence or willful misconduct of the Trustee. The
                   Company shall have the right, but not the obligation, to
                   conduct the defense of any action to which this Section
                   applies. The Plan fiduciaries are not entitled to indemnity
                   from the Plan assets relating to any such action.

19       AMENDMENT, MERGER, DIVESTITURES AND TERMINATION

         19.1     Amendment

                  The Company reserves the right to amend the Plan and Trust at
                  any time, to any extent and in any manner it may deem
                  necessary or appropriate. The Company (and not the Trustee)
                  shall be responsible for adopting any amendments necessary to
                  maintain the qualified status of the Plan and Trust under Code
                  sections 401(a) and 501(a). If the Committee is acting as the
                  Administrator in accordance with Section 15.6, it shall have
                  the authority to adopt Plan and Trust amendments which have no
                  substantial adverse financial impact upon any Employer or the
                  Plan. All interested parties shall be bound by any amendment,
                  provided that no amendment shall:

                  (a)      become effective unless it has been adopted in
                           accordance with the procedures set forth in Section
                           19.5;

                  (b)      except to the extent permissible under ERISA and the
                           Code, make it possible for any portion of the Trust
                           assets to revert to an Employer or to be used for, or
                           diverted to, any purpose other than for the exclusive
                           benefit of Participants and Beneficiaries entitled to
                           Plan benefits and to defray reasonable expenses of
                           administering the Plan;

                  (c)      decrease the rights of any Employee to benefits
                           accrued (including the elimination of optional forms
                           of benefits) to the date on which the amendment is
                           adopted, or if later, the date upon which the
                           amendment becomes effective, except to the extent
                           permitted under ERISA and the Code; nor

                  (d)      permit an Employee to be paid the balance of his or
                           her 401(k) Account unless the payment would otherwise
                           be permitted under Code section 401(k).

         19.2     Merger

                  The Plan and Trust may not be merged or consolidated with, nor
                  may its assets or liabilities be transferred to, another plan
                  unless each Participant and Beneficiary would, if the
                  resulting plan were then terminated, receive a benefit just
                  after the merger, consolidation or transfer which is at least
                  equal to the benefit which would be received if either plan
                  had terminated just before such event.

         19.3     Divestitures

                  In the event of a sale by an Employer which is a corporation
                  of: (1) substantially all of the Employer's assets used in a
                  trade or business to an unrelated corporation, or (2) a sale
                  of such Employer's interest in a subsidiary


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


                                                                                

                                       61

<PAGE>   68



                   to an unrelated entity or individual, lump sum distributions
                   shall be permitted from the Plan, except as provided below,
                   to Participants with respect to Employees who continue
                   employment with the corporation acquiring such assets or who
                   continue employment with such subsidiary, as applicable.

                   Notwithstanding, distributions shall not be permitted if the
                   purchaser agrees, in connection with the sale, to be
                   substituted as the Company as the sponsor of the Plan or to
                   accept a transfer of the assets and liabilities representing
                   the Participants' benefits into a plan of the purchaser or a
                   plan to be established by the purchaser.

         19.4     Plan Termination

                  The Company may, at any time and for any reason, terminate the
                  Plan in accordance with the procedures set forth in Section
                  19.5, or completely discontinue contributions. Upon either of
                  these events, or in the event of a partial termination of the
                  Plan within the meaning of Code section 411(d)(3), the
                  Accounts of each affected Employee who has not yet incurred a
                  Break in Service shall be fully vested. If no successor plan
                  is established or maintained, lump sum distributions shall be
                  made in accordance with the terms of the Plan as in effect at
                  the time of the Plan's termination or as thereafter amended
                  provided that a post-termination amendment shall not be
                  effective to the extent that it violates Section 19.1 unless
                  it is required in order to maintain the qualified status of
                  the Plan upon its termination. The Trustee's and Employer's
                  authority shall continue beyond the Plan's termination date
                  until all Trust assets have been liquidated and distributed.

         19.5     Amendment and Termination Procedures

                  The following procedural requirements shall govern the
                  adoption of any amendment or termination (a "Change") of the
                  Plan and Trust:

                  (a)      The Company may adopt any Change by action of its
                           board of directors in accordance with its normal
                           procedures.

                  (b)      The Committee, if acting as Administrator in
                           accordance with Section 15.6, may adopt any amendment
                           within the scope of its authority provided under
                           Section 19.1 and in the manner specified in Section
                           15.7(a).

                  (c)      Any Change must be (1) set forth in writing, and (2)
                           signed and dated by an executive officer of the
                           Company or, in the case of an amendment adopted by
                           the Committee, at least one of its members.

                  (d)      If the effective date of any Change is not specified
                           in the document setting forth the Change, it shall be
                           effective as of the date it is signed by the last
                           person whose signature is required under clause (2)
                           above,


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


                                                                                

                                       62

<PAGE>   69



                            except to the extent that another effective date is
                            necessary to maintain the qualified status of the
                            Plan and Trust under Code sections 401(a) and
                            501(a).

                   (e)      No Change shall become effective until it is
                            accepted and signed by the Trustee (which acceptance
                            shall not unreasonably be withheld).

         19.6      Termination of Employer's Participation

                   Any Employer may, at any time and for any reason, terminate
                   its Plan participation by action of its board of directors in
                   accordance with its normal procedures. Written notice of such
                   action shall be signed and dated by an executive officer of
                   the Employer and delivered to the Company. If the effective
                   date of such action is not specified, it shall be effective
                   on, or as soon as reasonably practicable after, the date of
                   delivery. Upon the Employer's request, the Company may
                   instruct the Trustee and Administrator to spin off all
                   affected Accounts and underlying assets into a separate
                   qualified plan under which the Employer shall assume the
                   powers and duties of the Company. Alternatively, the Company
                   may treat the event as a partial termination described above
                   or continue to maintain the Accounts under the Plan.

         19.7      Replacement of the Trustee

                   The Trustee may resign as Trustee under the Plan and Trust or
                   may be removed by the Company at any time upon at least 90
                   days written notice (or less if agreed to by both parties).
                   In such event, the Company shall appoint a successor trustee
                   by the end of the notice period. The successor trustee shall
                   then succeed to all the powers and duties of the Trustee
                   under the Plan and Trust. If no successor trustee has been
                   named by the end of the notice period, the Company's chief
                   executive officer shall become the trustee, or if he or she
                   declines, the Trustee may petition the court for the
                   appointment of a successor trustee.

         19.8      Final Settlement and Accounting of Trustee

                   (a)     Final Settlement. As soon as administratively
                           feasible after its resignation or removal as Trustee,
                           the Trustee shall transfer to the successor trustee
                           all property currently held by the Trust. However,
                           the Trustee is authorized to reserve such sum of
                           money as it may deem advisable for payment of its
                           accounts and expenses in connection with the
                           settlement of its accounts or other fees or expenses
                           payable by the Trust. Any balance remaining after
                           payment of such fees and expenses shall be paid to
