                          PENNZOIL-QUAKER STATE COMPANY
                           SAVINGS AND INVESTMENT PLAN

               (As Amended and Restated Effective January 1, 2001)

                                    RECITALS

                  Pennzoil Company, a Delaware corporation ("Pennzoil"),
established the Pennzoil Company Savings and Investment Plan (the "Superceded
Plan"), effective December 20, 1986, for the benefit of its eligible employees
and the eligible employees of certain other corporations which could adopt the
Superceded Plan.

                  As part of the Superceded Plan, Pennzoil established a trust,
effective December 20, 1986, to hold and administer funds contributed under the
Superceded Plan for the exclusive benefit of participants and beneficiaries
thereunder. Effective as of January 1, 1989, the Board of Directors of Pennzoil
authorized the amendment, restatement and continuation of the Superceded Plan to
comply with the provisions of the Tax Reform Act of 1986 and to make certain
other changes therein, including changes relating to investment fund
alternatives and employee loans, effective January 1, 1994.

                  Effective as of December 30, 1998 (the "Distribution Date")
Pennzoil consolidated its motor oil, refined products and fast lube operations
under Pennzoil Products Company ("PPC"), spun-off PPC, renamed PPC
"Pennzoil-Quaker State Company" (the "Company") and merged the Company's wholly
owned subsidiary, "Merger-Sub" into Quaker State Corporation (the "Merger") with
Quaker State Corporation surviving as a wholly owned subsidiary of the Company.
Concurrent with the Merger, the Board of Directors of Pennzoil also authorized
the transfer of the accounts of those former employees of Pennzoil who as of
January 1, 1999 became employees of the Company from the trust for the
Superceded Plan to the trust established under the terms of the Pennzoil-Quaker
State Company Savings and Investment Plan (the "Prior Plan").

                  Effective as of January 1, 2001 (the "Effective Date"), the
Board of Directors of the Company authorized the amendment and restatement of
the Prior Plan and the merger of the Pennzoil-Quaker State Company Thrift and
Stock Purchase Plan, the Medo Industries, Inc. Profit Sharing and 401(k) Plan
and the Axius Auto Shade Inc. 401(k) Profit Sharing Plan (collectively the
"Merged Plans") into the Prior Plan as amended and restated.

                  As part of the Plan, the Company also established a trust as
of the Effective Date to hold and administer the funds transferred from the
Prior Plan and the Merged Plans and funds contributed under this Plan for the
exclusive benefit of participants and beneficiaries hereunder. It is intended
that said trust shall form a part of the Plan set forth herein.

                  There shall be no termination and no gap or lapse in time or
effect between the Prior Plan, the Merged Plans and this Plan, and the existence
of a qualified plan shall be uninterrupted. The provisions of this Plan shall
apply to a Member who terminates Service on or after January 1, 2001. The rights
and benefits, if any, of a former employee shall be determined





in accordance with the provisions of the applicable Prior Plan or Merged Plan in
effect on the date his employment terminated.

                  The purpose of this Plan is to encourage employees to save,
and invest systematically, a portion of their current compensation in order that
they may have an additional source of income upon their retirement, disability,
or for their family in the event of their death. The benefits provided hereunder
will be in addition to benefits employees are entitled to receive under any
other employee benefit programs of the Company and under the Federal Social
Security Act.

                  This Plan and its related trust are intended to meet the
requirements of Sections 401(a), 401(k) and 501(a) of the Internal Revenue Code
of 1986, and of the Employee Retirement Income Security Act of 1974, as either
may be amended from time to time.

NOW, THEREFORE, Pennzoil-Quaker State Company hereby authorizes the merger,
amendment and restatement of the Pennzoil-Quaker State Company Savings and
Investment Plan as follows:

provisions of the Plan or the Trust Agreement, as the case may be, authorizing
or providing for such direction, information or action. Furthermore, each
Fiduciary may rely upon any such direction, information or action of another
Fiduciary as being proper under this Plan or the Trust Agreement, and is not
required under this Plan or the Trust Agreement to inquire into the propriety of
any such direction, information or action. It is intended under this Plan and
the Trust Agreement that each Fiduciary shall be responsible for the proper
exercise of its own powers, duties, responsibilities and obligations under this
Plan and the Trust Agreement and shall not be responsible for any act or failure
to act of another Fiduciary. No Fiduciary guarantees the Trust Fund in any
manner against investment loss or depreciation in asset value.

whether the financial statements and related schedules required to be filed with
the Department of Labor or furnished to each Member are presented fairly and in
conformity with generally accepted accounting principles applied on a basis
consistent with that of the preceding Plan Year. If, however, the statements
required to be submitted as part of the reports to the Department of Labor are
prepared by a bank or similar institution or insurance carrier regulated and
supervised and subject to periodic examination by a state or federal agency and
if such statements are certified by the preparer as accurate and if such
statements are, in fact, made a part of the annual report to the Department of
Labor and no such audit is required by ERISA, then the audit required by the
foregoing provisions of this Section shall be optional with the Committee.

         2.13 Funding Policy: The Investment Committee shall, at a meeting duly
called for such purpose, establish a funding policy and method consistent with
the objectives of the Plan and the requirements of Title I of ERISA. The
Investment Committee shall meet at least annually to review such funding policy
and method. In establishing and reviewing such funding policy and method, the
Investment Committee shall endeavor to determine the Plan's short-term and
long-term objectives and financial needs, taking into account the need for
liquidity to pay benefits and the need for investment growth. All actions of the
Investment Committee taken pursuant to this Section and the reasons therefor
shall be recorded in the minutes of meetings of the Investment Committee and
shall be communicated to the Trustee, any investment manager who may be managing
a portion or all of the Trust Fund in accordance with the provisions of the
Trust Agreement, the Administrative Committee and the Board of Directors.

         2.14 Allocation and Delegation of Committee Responsibilities: Upon the
approval of a majority of the members of the Committee, the Committee may (i)
allocate among any of the members of the Committee any of the responsibilities
of the Committee under the Plan and Trust Agreement and/or (ii) designate any
person, firm or corporation that is not a member of the Committee to carry out
any of the responsibilities of the Committee under the Plan and Trust Agreement.
Any such allocation or designation shall be made pursuant to a written
instrument executed by a majority of the members of the Committee.

         recommence) on the date he first performs an "hour of service" within
         the meaning of Department of Labor Regulation Section 2530.200b-2(a)(1)
         for an Employer or Affiliate. All periods of Service shall be
         aggregated so that a one-year period of Service shall be completed as
         of the date the Employee or Member completes 12 months of Service (30
         days shall be deemed to be a month in the case of the aggregation of
         fractional months), or 365 days of Service.

                           Hours of Service will be credited for employment with
         other members of an affiliated service group (under Code Section
         414(m)), a controlled group of corporations (under Code Section
         414(b)), or a group of trades or businesses under common control (under
         Code Section 414(c)), of which the Employer is a member. Hours of
         Service will also be credited for any individual considered an Employee
         for purposes of this Plan under Code Section 414(n).

                  (c) Termination of Service: A period of Service of an Employee
         or Member shall terminate on the date of the first to occur of (i) his
         retirement or death, (ii) his quitting or discharge, (iii) his deemed
         date of termination of employment pursuant to his failure to return to
         work upon the expiration of such an authorized leave of absence or (iv)
         one year from the date the Employee or Member is absent from active
         employment for any reason other than retirement, quitting, discharge,
         authorized leave of absence or death. For purposes of clause (iii)
         immediately above, an Employee's or Member's deemed date of termination
         shall be the earlier of (A) the expiration date of such authorized
         leave of absence and (B) one year from the date such authorized leave
         of absence commenced.

         3.5 Break In Service: For purposes of the Plan, a "Break In Service"
shall occur upon the expiration of the 12 consecutive month period next
following an Employee's or Member's termination of Service (as determined in
accordance with the provisions of Section 3.4(c)



                                       14


hereof), unless such Employee or Member sooner recommences Service with an
Employer or Affiliate.

                  Solely for purposes of determining whether a Break In Service
has occurred for participation and vesting purposes under this Plan, the Service
of an individual who is absent from work for maternity or paternity reasons
shall not terminate until the expiration of 2 years after the date such absence
commenced. For purposes of this paragraph, an absence from work for maternity or
paternity reasons means an absence (a) by reason of the pregnancy of the
individual, (b) by reason of the birth of a child of the individual, (c) by
reason of the placement of a child with the individual in connection with the
adoption of such child by such individual or (d) for purposes of caring for such
child for a period beginning immediately following such birth or placement.

         3.6 Participation and Service Upon Re-Employment: Upon the
re-employment of any person on or after the Effective Date who had previously
been employed by an Employer or Affiliate, the following rules shall apply in
determining his eligibility for participation under Section 3.1 and his Service
under Section 3.4:

                  (a) Participation: If the re-employed person was not a Member
         during his prior period of Service, he must meet the requirements of
         Section 3.1 for participation in the Plan as if he were a new Employee.
         If the re-employed person was a Member in the Plan during his prior
         period of Service, he shall be entitled to recommence participation as
         of the date of his re-employment, and may also be entitled to a
         reinstatement of the amount previously forfeited from his prior
         Employer Contribution Account as provided in Section 7.4.

                  (b) Service: Any Service attributable to his prior period of
         Service shall be reinstated as of the date of his re-employment but
         only for purposes of vesting under Section 7.4. In addition, in the
         event an Employee or Member recommences Service with an Employer or
         Affiliate prior to incurring a Break In Service, the period of his
         interim absence shall also constitute Service for purposes of Section
         7.4.

         3.7 Transferred Members: If a Member is transferred to an Affiliate, or
to an employment classification with an Employer which is not covered by this
Plan, his participation shall be suspended until he is subsequently re-employed
by an Employer in an employment classification covered by the Plan; provided,
however, that during such suspension period (i) such Member shall be credited
with Service in accordance with Section 3.4, (ii) he shall not be entitled or
required to make Contributions under Section 4.1 or 4.3, (iii) his Employer
Contribution Account shall receive no Employer Contribution allocations except
to the extent provided in Sections 4.2 and 5.2 and (iv) his Account shall
continue to share proportionately in Income of the Trust Fund as provided in
Section 5.2. If an Employee is transferred from an employment classification
with an Employer that is not covered by the Plan to an employment classification
that is so covered, or from an Affiliate to an employment classification with an
Employer that is so covered, his period of Service prior to the date of transfer
shall be considered



                                       15


for purposes of determining his eligibility to become a Member under Section 3.1
and for purposes of vesting under Section 7.4.

                  In the event an employee of an Affiliate is transferred to
employment with an Employer in an employment classification covered by this Plan
and such Affiliate provides a thrift, savings or profit-sharing plan of like
nature and intent as this Plan in which the employee was a participant
immediately preceding his transfer, such employee's account balance in a
domestic Affiliate's defined contribution plan qualified under Section 401(a) of
the Code, determined on the valuation date coincident with or next following the
date of the employee's transfer, will, subject to the approval of the Committee,
be transferred to the Trust Fund held under this Plan and allocated among the
Investment Funds in accordance with the provisions of Section 9.3 hereof. In the
event a Member under this Plan is transferred to employment with an Affiliate
and such Affiliate provides a thrift, savings or profit-sharing plan of like
nature and intent as this Plan in which the Member will be eligible to
participate as an employee of such Affiliate, such Member's account balances in
this Plan, determined as of the valuation date coincident with or next following
the date of the Member's transfer, will, subject to the approval of the plan
administrator of the Affiliate's plan, be transferred to such plan and allocated
between the investment funds held thereunder in accordance with the provisions
thereof. For purposes of this paragraph, all references to "Affiliate" shall
include employment classifications with an Employer.

         3.8 Beneficiary Upon Death: Upon the death of a Member, his Account
shall be distributed to the Member's surviving spouse, but if there is no
surviving spouse, or if the surviving spouse has already consented by a
qualified election pursuant to Section 3.9, to the Beneficiary or Beneficiaries
designated by the Member in a written designation filed with his Employer, or if
no such designation shall have been so filed, to his estate. No designation of
any Beneficiary other than the Member's surviving spouse shall be effective
unless in writing and received by the Member's Employer, and in no event shall
it be effective as of a date prior to such receipt. The former spouse of a
Member shall be treated as a surviving spouse to the extent provided under a
qualified domestic relations order as described in Section 414(p) of the Code.
As soon as possible after an Employee has become a Member he shall file with the
Committee a written designation, in the form prescribed by the Committee, of the
Beneficiary to receive benefits payable hereunder upon his death. The Member may
at any time change or cancel any such designation on a form prescribed by the
Committee. The last such designation received by the Committee shall be
controlling over any testamentary or other disposition; provided, however, that
no designation or change or cancellation thereof shall be effective prior to the
Member's death, and in no event shall it be effective as of a date prior to such
receipt. If the Committee shall be in doubt as to the right of any Beneficiary
designated by a deceased Member to take the interest of such decedent, the
Committee may direct the Trustee to pay the amount in question to the estate of
such Member, in which event the Trustee, the Employer, the Committee and any
other person in any manner connected with the Plan shall have no further
liability in respect of the amount so paid.

         3.9 Qualified Election: The Member's spouse may waive the right to
receive the Member's full vested Account balance. The election to waive the
Member's full vested Account



                                       16


balance must designate a Beneficiary which may not be changed without spousal
consent (or the consent of the spouse must expressly permit designation by the
Member without any requirement of further consent of the spouse). A consent that
permits designations by the Member without all requirement of further consent by
the spouse must acknowledge that the spouse has the right to limit consent to a
specific beneficiary and that the spouse voluntarily elects to relinquish such
right. The waiver must be in writing and the Member's spouse must acknowledge
the effect of the waiver. The spouse's consent to a waiver must be witnessed by
a Plan representative or a notary public. The Member may file a waiver without
the spouse's consent if it is established to the satisfaction of the Committee
that such written consent may not be obtained because there is no spouse or the
spouse may not be located. Any consent under this Section 3.9 will be valid only
with respect to the spouse who signs the consent. Additionally, a revocation of
a prior waiver may be made by a Member without the consent of the spouse at any
time before the distribution of the Account. The number of revocations shall not
be limited.

         3.10 Penreco Employees: Effective September 1, 2001, pursuant to an
agreement between the Company and Penreco, Penreco will withdraw as an Employer
under the Plan and Penreco employees will no longer be Members of the Plan;
provided, however, that a former Penreco Member's service with Penreco
subsequent to September 1, 2001, subject to the Break In Service provisions in
3.5, shall be counted as Service under the Plan for purposes of vesting in such
former Member's Employer Contribution Account.

         3.11 Qualified Military Service: Notwithstanding any provision of this
Plan to the contrary, contributions, benefits and service credit with respect to
Qualified Military Service will be provided in accordance with Section 414(u) of
the Code. Qualified Military Service shall mean any service in the uniformed
services, as defined in Chapter 43 of Title 38 of the United States Code, by any
individual who is entitled to re-employment rights under such chapter with
respect to such service.



                                       17


                                   ARTICLE IV

                          CONTRIBUTIONS AND FORFEITURES

         4.1 Pre-Tax Contributions: Each eligible Employee who elects to make
Pre-Tax Contributions for a Plan Year shall initially elect to defer a portion
of his salary in whole percentages of not less than 1% and not more than 15% of
his Compensation; provided, however, that Pre-Tax Contributions under this
Section 4.1 shall not total more than $10,500 per Plan Year (as adjusted upward
by the Secretary of the Treasury to reflect increases in the cost-of-living).

                  Each Member's Pre-Tax Contribution shall be contributed to the
Trust Fund by the Employer. Each such election shall be made pursuant to the
provisions of Section 3.3 and shall continue in effect during subsequent Plan
Years unless the Member shall notify the Committee in the manner hereinafter
provided of his election to change or discontinue his Pre-Tax Contribution rate
as provided in Section 4.5. Each Member's Pre-Tax Contribution Account shall be
fully vested and non-forfeitable at all times.

                  In the event a Member's Pre-Tax Contributions exceed the
applicable limit described in the previous sentence, or in the event the Member
submits a written claim to the Committee, at the time and in the manner
prescribed by the Committee, specifying an amount of Pre-Tax Contributions that
will exceed the applicable limit of Section 402(g) of the Code when added to
amounts deferred by the Member in other plans or arrangements, such excess (the
"Excess Deferrals"), plus any income and minus any loss attributable thereto for
the Plan Year in which the Excess Deferral occurred shall be returned to the
Member by April 15 of the following year. The amount of any Excess Deferrals to
be distributed to a Member for a taxable year shall be reduced by excess Pre-Tax
Contributions previously recharacterized or distributed pursuant to Article XIII
for the Plan Year beginning in such taxable year. The income or loss
attributable to the Member's Excess Deferral for the Plan Year shall be
determined by multiplying the income or loss attributable to the Member's
Pre-Tax Contribution Account balance for the Plan Year (or relevant portion
thereof) by a fraction, the numerator of which is the Excess Deferral and the
denominator of which is the Member's total Pre-Tax Contribution Account balance
as of the Valuation Date next preceding the date of return of the Excess
Deferral. For these purposes, distribution of an Excess Deferral on or before
the 15th day of a calendar month shall be treated as having been made on the
last day of the preceding month, and a distribution made thereafter shall be
treated as having been made on the first day of the next month. Excess Deferrals
shall be treated as Annual Additions under Article V of the Plan.

         4.2 Employer Matching Contributions: For each Plan Year, each Employer
shall make a Matching Contribution to the Trust Fund on behalf of its Eligible
Members in an amount equal to 100% of the first 6% of the total Pre-Tax
Contributions elected or contributed by its Eligible Members during such Plan
Year.

                  A contribution shall be deemed to be made on account of a Plan
Year if the Board of Directors of the Employer determines the amount of such
Contribution by appropriate action and either (i) the Employer claims such
amount as a deduction on its Federal income tax return



                                       18


for such Plan Year or (ii) the Employer designates such amount in writing to the
Trustee as payment on account of such Plan Year. All Contributions of the
Employer shall be paid to the Trustee, and payment shall be made not later than
the time prescribed by law for filing the Federal income tax return of the
Employer, including any extension which has been granted for the filing of such
tax return. The Trustee shall hold all such Employer Matching Contributions
subject to the provisions of this Plan and the Trust Agreement, and no part of
such Contributions shall be used for, or diverted to, any other purpose.

                  In the case of the reinstatement of any amounts forfeited
under Section 7.4 or pursuant to the unclaimed benefit provisions of Section
11.10, the Employer shall also contribute, within a reasonable time after the
repayment described in Section 7.4 or after a claim is filed under Section
11.10, a Minimum Contribution in an amount sufficient when added to Forfeitures
to reinstate such amounts. All such Employer Matching Contributions shall be
transmitted to the Trustee as soon as practicable after such Contributions are
made.

         4.3 Employer Matching Contributions and Pre-Tax Contributions to be Tax
Deductible: Employer Matching Contributions and Pre-Tax Contributions shall not
be made in excess of the amount deductible under applicable Federal law now or
hereafter in effect limiting the allowable deduction for contributions to
profit-sharing plans. The Employer Matching Contributions and Pre-Tax
Contributions to this Plan when taken together with all other contributions made
by the Employer to other qualified retirement plans shall not exceed the maximum
amount deductible under Section 404 of the Code.

         4.4 Change of Elections and Suspension of Allotments: Any Member may
increase or decrease the percentage of his salary designated as Pre-Tax
Contributions, but not retroactively or suspend his Pre-Tax Contribution
entirely and such change shall be effective as soon as reasonably practicable
following receipt of the change of elections. In the case of total suspension of
Pre-Tax Contributions, the Employer Matching Contribution will automatically
cease. Pre-Tax Contributions which are not made during a period of suspension
shall not be made retroactively. All such changes of elections related to
contributions in the investments of Accounts shall be made by ARU, internet or
through a Plan representative.

         4.5 Delivery to Trustee: Each Employer shall, not less frequently than
monthly, pay the Contributions to the Trustee.

         4.6 Application of Funds: The Trustee shall hold or apply the
Contributions so received by it subject to the provisions of the Plan; and no
part thereof (except as otherwise provided in the Trust Agreement) shall be used
for any purpose other than the exclusive use of the Members or their
Beneficiaries.

         4.7 Disposition of Forfeitures: In any case in which a Member is not
entitled to the full amount in his Employer Contribution Account, the amount to
which he is not entitled shall be forfeited, and shall be allocated in the
following order:

                  (a) First, such Forfeitures shall be allocated to reinstate
         any Employer Matching Contribution Accounts of Members who return to
         Service and are



                                       19


         entitled to reinstatement of their Employer Contribution Account in
         accordance with Section 7.4.

                  (b) Second, such Forfeitures shall be applied to restore any
         amounts forfeited under the unclaimed benefits provisions of Section
         11.10.

                  (c) Third, such Forfeitures shall be applied against the next
         succeeding Employer Matching Contribution.

         4.8 Rollover Accounts: Any Employee who is otherwise eligible to
participate in the Plan but who has not yet completed the participation
requirements of Section 3.1 may file with the Committee a written request that
the Trustee accept a Rollover Amount from such Employee provided, however, that
such Rollover Amount shall be transferred only in the form of cash. The
Committee shall develop such procedures and may require such information from
the Employee desiring to make such a transfer as it deems necessary or desirable
to determine that the proposed transfer will meet the requirements of this
Section and of the Code. Upon approval by the Committee, the amount transferred
shall be deposited in the Trust Fund and shall be credited to a separate
Rollover Account. Such account shall at all times be fully vested and
non-forfeitable, shall share in the Income of the Trust Fund in accordance with
Section 5.2, but shall not share in Employer Matching Contribution allocations.
Upon termination of employment, the total amount of the Rollover Account shall
be distributed in accordance with Article VIII. Notwithstanding anything in this
Plan to the contrary, no such transfer of a Rollover Amount shall include a
transfer of benefits from a defined benefit plan or from a defined contribution
plan subject to Code Section 412.

                  Upon such a transfer by an Employee who is otherwise eligible
to participate in the Plan but who has not yet completed the participation
requirements of Section 3.1, his Rollover Account shall represent his sole
interest in the Plan until he becomes a Member. In all respects, the Rollover
Account shall be treated as a regular account under this Plan and shall be
subject to the investment directions of the Member and the change thereof as
otherwise permitted herein.

         4.9 Prior Plan Accounts: The Committee shall instruct the Trustee to
accept a transfer of a Member's Prior Plan Account. Any such transferred assets
shall be maintained in the Trust Fund on behalf of the Member as a separate
account under this Plan. Any cash dividends or other income paid with respect to
the Account shall be reinvested in Pennzoil-Quaker State Company Common Stock.
Such Prior Plan Account shall at all times be 100% vested in the Employee or
Member, and shall not share in the Income of the Trust Fund in accordance with
Section 5.2 or in Employer Matching Contribution allocations. Subject to such
rules and procedures as may be adopted by the Committee and communicated to
Members, any Member who has a Prior Plan Account may withdraw all of the vested
portion of such account by giving the Committee appropriate timely written
notice of such withdrawal. Upon termination of employment, the total amount of
the Prior Plan Account shall be distributed in kind in accordance with Article
VIII. The Prior Plan Account shall have two subaccounts, the first to be known
as the Prior Plan Employee Account and representing the Prior Plan Member's
balance in his Employee Account held under the Prior Plan and transferred to
this Plan, and the



                                       20


second to be known as the Prior Plan Employer Account and representing the
balance of the Company Account held for such Member under the applicable Prior
Plan and transferred to this Plan. As provided under Sections 9.2, 9.3 and 9.4
of the Plan, a Member who has a Prior Plan Account may elect to invest all or
any part of such Prior Plan Account in any of the Investment Funds authorized
under Section 9.3.



                                       21


                                    ARTICLE V

                                 MEMBER ACCOUNTS

         5.1 Individual Accounts: The Committee shall create and maintain
adequate records to disclose the interest in the Trust Fund and in its component
Investment Funds of each Member, former Member and Beneficiary. Such records
shall be in the form of individual accounts and credits and charges shall be
made to such accounts in the manner herein described. A Member may have up to
five separate accounts, an Employer Contribution Account, a Pre-Tax Contribution
Account, an After-Tax Contribution Account, a Prior Plan Account and a Rollover
Account. The Prior Plan Account shall have two subaccounts as provided in
Section 4.10 above. Any Member who transfers from one Employer to another
Employer, or who is simultaneously employed by two or more Employers, may have
individual accounts with each such Employer. The maintenance of individual
Accounts is only for accounting purposes, and a segregation of the assets of the
Trust Fund to each Account shall not be required. Distribution and withdrawals
made from an Account shall be charged to the Account as of the date paid.

         5.2 Account Adjustments: Except with respect to Employer Matching
Contributions which shall be allocated bi-weekly among Eligible Members, the
accounts of Members, former Members and Beneficiaries shall be adjusted daily.
Forfeitures which have become available for reallocation shall be applied
pursuant to Section 4.7 and Employer Minimum Contributions shall be used solely
to reinstate Accounts in accordance with Section 7.4 and to restore Accounts
pursuant to Section 11.10 whenever the Forfeitures available for such
reinstatement or restoration are insufficient.

         5.3 Limitations on Contributions: Notwithstanding any provision of this
Plan to the contrary, the total Annual Additions made to the account of a Member
for any Limitation Year (the Plan Year) shall be subject to the following
limitations:

         I. Single Defined Contribution Plan

                           1. If an Employer does not maintain any other
                  qualified plan, the amount of Annual Additions which may be
                  allocated under this Plan on a Member's behalf for a
                  Limitation Year shall not exceed the lesser of the Maximum
                  Permissible Amount or any other limitation contained in this
                  Plan.

                           2. Prior to the determination of the Member's actual
                  Compensation for a Limitation Year, the Maximum Permissible
                  Amount may be determined on the basis of the Member's
                  estimated annual Compensation for such Limitation Year. Such
                  estimated annual Compensation shall be determined on a
                  reasonable basis and shall be uniformly determined for all
                  Members similarly situated. Any Employer contributions
                  (including allocation of forfeitures) based on estimated
                  annual



                                       22


                  Compensation shall be reduced by any Excess Amounts carried
                  over from prior years.

                           3. As soon as is administratively feasible after the
                  end of the Limitation Year, the Maximum Permissible Amount for
                  such Limitation Year shall be determined on the basis of the
                  Employee's actual Compensation for such Limitation Year.

                           4. If there is an Excess Amount with respect to a
                  Member for the Limitation Year, there shall first be returned
                  to the Member (i) his After-Tax Contributions attributable to
                  that Limitation Year, and then (ii) his Pre-Tax Contributions
                  attributable to that Limitation Year, to the extent such
                  returned Contributions would reduce the Excess Amount. Then,
                  Excess Amounts will be treated as a forfeiture and shall be
                  applied as a credit to subsequent Employer contributions or
                  reallocated to other Employees to the extent such allocations
                  do not exceed the Maximum Permissible Amount. Any Excess
                  Amounts that cannot be allocated will be held in a suspense
                  account. All amounts in the suspense account must be allocated
                  and reallocated to the Employee's accounts (subject to the
                  limitations of Section 415) in succeeding Limitation Years
                  before any Employer contribution and non-deductible employee
                  contribution which would constitute Annual Additions may be
                  made to the Plan.

                                    If a suspense account is in existence at any
                  time during the Limitation Year pursuant to this Section, it
                  will not participate in the allocation of the Trust's
                  investment gains and losses.

         II. Two or More Defined Contribution Plans

                           1. If, in addition to this Plan, the Employer
                  maintains any other qualified defined contribution plan, the
                  amount of Annual Additions which may be allocated under this
                  Plan on a Member's behalf for a Limitation Year shall not
                  exceed the lesser of:

                                    A. the Maximum Permissible Amount, reduced
                           by the sum of any Annual Additions allocated to the
                           Member's accounts for the same Limitation Year under
                           this Plan and such other defined contribution plans;
                           or

                                    B. any other limitation contained in this
                           Plan.



                                       23


                           2. Prior to the determination of the Member's actual
                  Compensation for the Limitation Year, the amount referred to
                  in Section 1(A) above, may be determined on the basis of the
                  Member's estimated annual Compensation for such Limitation
                  Year. Such estimated annual Compensation shall be determined
                  on a reasonable basis and shall be uniformly determined for
                  all Members similarly situated. Any Employer contribution
                  (including allocation of forfeitures) based on estimated
                  annual Compensation shall be reduced by any Excess Amounts
                  carried over from prior years.

                           3. As soon as is administratively feasible after the
                  end of the Limitation Year, the amounts referred to in Section
                  1(A) above shall be determined on the basis of the Member's
                  actual Compensation for such Limitation Year.

                           4. If a Member's Annual Additions under this Plan and
                  all such other defined contribution plans result in an Excess
                  Amount, such Excess Amount shall be deemed to consist of the
                  amounts last allocated.

                           5. If an Excess Amount was allocated to a Member on
                  an allocation date of this Plan which coincides with an
                  allocation date of another plan, the Excess Amount attributed
                  to this Plan will be the product of:

                                    A. the total Excess Amount allocated as of
                           such date (including any amount which would have been
                           allocated but for the limitations of Section 415 of
                           the Code); times

                                    B. the ratio of (A) the amount allocated to
                           the Member as of such date under this Plan, divided
                           by (B) the total amount allocated as of such date
                           under all qualified defined contribution plans
                           (determined without regard to the limitations of
                           Section 415 of the Code).

                           6. Any Excess Amounts attributed to this Plan shall
                  be disposed of as provided in Section 5.3(I)(4).

         III. Definitions

                           1. Employer: The Company and any other Employer that
                  adopts this Plan. In the case of a group of employers which
                  constitutes a controlled group of corporations (as defined in
                  Section 414(b) of the Code as modified by Section 415(h)) or
                  which constitutes trades and businesses (whether or not
                  incorporated) which are under common control (as defined in



                                       24


                  Section 414(c) as modified by Section 415(h)) or an affiliated
                  service group (as defined in Section 414(m)), all such
                  employers shall be considered a single Employer for purposes
                  of applying the limitations of these sections.

                           2. Excess Amount: The excess of the Member's Annual
                  Additions for the Limitation Year over the Maximum Permissible
                  Amount.

                           3. Limitation Year: A 12 consecutive month period
                  ending on December 31.

                           4. Maximum Permissible Amount: For a Limitation Year,
                  the Maximum Permissible Amount with respect to any Member
                  shall be the lesser of:

                                    A. $30,000 as adjusted by the Secretary of
                           the Treasury or his delegate; or

                                    B. 25% of the Member's Compensation for the
                           Limitation Year.

                                    The Compensation limitation referred to in
                  subparagraph B above shall not apply to:

                                    (i) Any contribution for medical benefits
                  (within the meaning of Code Section 419A(f)(2)) after
                  separation from service which is otherwise treated as an
                  Annual Addition; or

                                    (ii) Any amount otherwise treated as an
                  Annual Addition under Code Section 415(l)(1).

                           5. Compensation: For purposes of determining
                  compliance with the limitations of Code Section 415,
                  Compensation shall mean a Member's earned income, wages,
                  salaries, fees for professional services and other amounts
                  received for personal services actually rendered in the course
                  of employment with an Employer maintaining the Plan,
                  including, but not limited to, commissions paid salesmen,
                  compensation for services on the basis of a percentage of
                  profits, commissions on insurance premiums, tips, and bonuses
                  and excluding the following:



                                       25


                                    (a) Employer contributions to a plan of a
                  deferred compensation to the extent contributions are not
                  included in gross income of the Employee for the taxable year
                  in which contributed, or on behalf of an employee to a
                  simplified employee pension plan to the extent such
                  contributions are deductible under Code Section 219(b)(2), and
                  any distributions from a plan of deferred compensation whether
                  or not includable in the gross income of the Employee when
                  distributed (however, any amounts received by an Employee
                  pursuant to an unfunded non-qualified plan may be considered
                  as compensation in the year such amounts are included in the
                  gross income of the Employee);

                                    (b) Amounts realized from the exercise of a
                  non-qualified stock option, or when restricted stock (or
                  property) held by an employee becomes freely transferable or
                  is no longer subject to a substantial risk of forfeiture;

                                    (c) amounts realized from the sale, exchange
                  or other disposition of stock acquired under a qualified stock
                  option; and

                                    (d) Other amounts which receive special tax
                  benefits, or contributions made by an Employer (whether or not
                  under a salary reduction agreement) towards the purchase of a
                  Section 403(b) annuity contract (whether or not the
                  contributions are excludable from the gross income of the
                  Employee).

         For purposes of applying the limitations in this Section, amounts
         included as compensation are those actually paid or made available to a
         Member within the Limitation Year. For Limitation Years beginning after
         December 31, 1999, Compensation shall be limited to $170,000 (as
         adjusted by the Secretary of the Treasury or his delegate in the manner
         as permitted under Code Section 415(d)). Notwithstanding anything to
         the contrary in the definition, Compensation under this shall include
         any and all items which may be includable in Compensation under Section
         415(c)(3) of the Code, including (i) any elective deferral (as defined
         in Code Section 402(g)(3)), and (ii) any amount which is contributed or
         deferred by the Employer and is not includable in the gross income of
         the Employee by reason of Code Section 125, 132 and 457.

                           6. Annual Benefit: A benefit payable annually in the
                  form of a straight life annuity (with no ancillary benefits)
                  under a plan to which Employees do not contribute and under
                  which no rollover contributions are made.

                           7. Annual Additions: With respect to each Limitation
                  Year, the total of the Employer Matching Contributions,
                  Pre-Tax



                                       26


                  Contributions, After-Tax Contributions, Forfeitures and
                  amounts described in Code Sections 415(l) and 419A(d)(2) which
                  are allocated to a Member's Account.

         5.4 Valuation of Trust Fund: A valuation of the Trust Fund shall be
made as of each Valuation Date and on any other date during the Plan Year that
the Committee deems a valuation to be advisable. Any such interim valuation
shall be exercised on a uniform and non-discriminatory basis. For the purposes
of each valuation, the assets of the Trust Fund shall be valued at the
respective current market values, and the amount of any obligations for which
the Trust Fund may be liable, as shown on the books of the Trustee, shall be
deducted from the total value of the assets. For the purposes of maintenance of
books of account in respect of properties constituting the Trust Fund, and of
making any such valuation, the Trustee shall account for the transactions of the
Trust Fund on a modified cash basis.

         5.5 Recognition of Different Investment Funds: As provided in Article
IX, Investment Funds shall be established, and each Member shall direct, within
the limitations set forth in Section 9.3, what portion of the balance in his
Accounts shall be deposited in each Investment Fund. Consequently, when
appropriate, a Member shall have a Pre-Tax Contribution Account, an After-Tax
Contribution Account and a Rollover Account in each such Investment Fund and the
allocations described in Section 5.2 shall be adjusted in such manner as is
appropriate to recognize the existence of the Investment Funds. Because Members
have a choice of Investment Funds, any reference in this Plan to a Pre-Tax
Contribution Account, an After-Tax Contribution Account or a Rollover Account
shall be deemed to mean and include all accounts of a like nature which are
maintained for the Member under each Investment Fund.



                                       27


                                   ARTICLE VI

                              VOLUNTARY WITHDRAWALS

         6.1 Withdrawal from After-Tax Contribution and Rollover Accounts: Each
Member of the Plan shall be entitled to withdraw from his After-Tax Contribution
Account and Rollover Account (valued as of the Valuation Date next preceding the
Member's election), any amount up to but not to exceed the balance of such
Account as of such date.

         6.2 Withdrawal from Employer Contribution Account: Each Member who has
been a Member of the Plan, for five Years may withdraw up to 100% of the amount
in his Employer Contribution Account as of the next preceding Valuation Date, by
giving notice (in such form and in such manner as prescribed by the Committee)
to the Committee. A withdrawal by a Member from his Employer Contribution
Account will be limited to one such withdrawal every five years. Notwithstanding
anything herein to the contrary, a withdrawal from any account consisting of
employer matching contributions in the Merged Plans shall be subject to the
provisions of such Merged Plans.

         6.3 Limitation on Withdrawals: Any provision of Section 6.2 hereof to
the contrary notwithstanding, an Employee on suspended status may not make a
withdrawal and an Employee must withdraw the entire amount in his After Tax
Contribution Account, Prior Plan Employer Accounts and Rollover Account, prior
to exercising his right to withdraw from his Employer Contribution Account.

         6.4 Withdrawal from Pre-Tax Contribution Account: Any Member who has
attained age 59 1/2 may withdraw all or any part of his Pre-Tax Contributions,
plus any earnings thereon, by filing an appropriate request therefor with the
Committee. A withdrawal from the Pre-Tax Contribution Account under this Section
shall not affect the Member's remaining rights hereunder.

         6.5 Hardship Withdrawals: A Member may at any time file with the
Committee an appropriate written request for a hardship withdrawal from his
Pre-Tax Contribution Account excluding any Income of the Trust Fund allocated to
his Pre-Tax Contribution Account (under the Plan or the Prior Plan) on or after
January 1, 1989. The approval or disapproval of such request shall be within the
sole discretion of the Committee. A Member must first withdraw any available
amount credited to his After Tax Contribution Account, Prior Plan Account,
Employer Contribution Account and Rollover Account, if any, in order to be
permitted to make a hardship withdrawal from his Pre-Tax Contribution Account
and must also have taken all distributions and loans otherwise available under
this Plan and all employee plans maintained by the Member's Employer. The Member
must certify that he is facing a hardship creating an immediate and substantial
financial need and that the resources necessary to satisfy that financial need
are not reasonably available from other sources available to the Member. The
amount of the hardship withdrawal shall be limited to that amount which the
Committee determines to be required to meet the immediate financial need created
by the hardship including anticipated federal and state income taxes and
penalties resulting from the distribution. The hardship withdrawal distribution
shall be made in cash as soon as practicable after the Member submits



                                       28


the hardship request and the dollar amount withdrawn shall be determined by
reference to the Pre-Tax Contribution Account as of the Valuation Date
immediately preceding the date of withdrawal. A Member who receives a hardship
withdrawal shall be prohibited from making pre-tax contributions and employee
contributions to this Plan and any other plan maintained by the Employer (except
"welfare plans" as defined in Section 3(1) of ERISA) for 365 days following the
date of distribution. In addition, the dollar limitation on the Pre-Tax
Contributions described in Section 4.1 shall be reduced (but not below zero) in
the Plan Year following the hardship withdrawal by the amount of Pre-Tax
Contributions made by the Member of the Plan Year during which the withdrawal
was made. The following standards (or such other standards as may be acceptable
under Treasury Regulations issued pursuant to Section 401(k) of the Code) shall
be applied by the Committee on a uniform and non-discriminatory basis in
determining the existence of such a hardship:

                  (i) To be considered a hardship for purposes of this Section,
         the event giving rise to the need for funds must relate to financial
         hardship resulting from:

                           (1) medical expenses (described in Code Section
                  213(d) previously incurred by the Member or the Member's
                  Spouse or dependents (as defined in Code Section 152) or
                  necessary for those persons to obtain medical care (as
                  evidenced by a written estimate thereof);

                           (2) purchase (excluding mortgage payments) of a
                  principal residence for the Member;

                           (3) payment for tuition for the next 12 months of
                  post secondary education for the Member or the Member's
                  spouse, children or dependents (as defined in Code Section
                  152); or

                           (4) the need to prevent the eviction of the Member
                  from his principal residence or foreclosure on the mortgage of
                  the Member's principal residence.

                           A person shall be considered to be dependent on the
         Member if the Member certifies that he reasonably expects to be
         entitled to claim that person as a dependent for Federal income tax
         purposes for a calendar year coinciding with the Plan Year in which the
         certification of hardship is made.

                  (ii) A financial need shall be considered immediate if it must
         be satisfied in substantial part within a period of 12 months from the
         date on which the Member certifies his eligibility for a hardship
         withdrawal.

         6.6 Loans to Members: A Member who is an Employee and, to the extent
not resulting in discrimination prohibited by Section 401(a)(4) of the Code, any
other Member or any Beneficiary (including an "alternate payee" within the
meaning of Code Section 414(p)(8)) who is a "party in interest" with respect to
the Plan within the meaning of ERISA Section 3(14)



                                       29


and who must be eligible to obtain a Plan loan in order for the exemption set
forth in 29 C.F.R. Section 2550.408b-1 to apply to the Plan, (hereinafter
"Borrower"), may make application to the Committee to borrow from the Accounts
maintained by or for the Borrower in the Trust Fund, and the Committee in its
sole discretion may permit such a loan. Any such loan shall be withdrawn from
the Borrower's Accounts in the following order: first, from the Rollover
Account, if any, second from the Prior Plan Account, if any, third from the
After-Tax Account, if any, fourth from the Employer Contribution Account and
last from the Pre-Tax Contribution Account. Loans shall be granted in a uniform
and nondiscriminatory manner on terms and conditions determined by the Committee
which shall not result in more favorable treatment of highly compensated
employees and shall be set forth in written procedures promulgated by the
Committee in accordance with applicable governmental regulations. All such loans
shall also be subject to the following terms and conditions:

                  (a) The amount of the loan shall not exceed the lesser of (i)
         $50,000, or (ii) 50% of the present value of the Borrower's vested
         Account balance under the Plan. In no event shall a loan of less than
         $1,000 be made to a Borrower. A Borrower may not have more than one
         loan outstanding at a time under this Plan and may not refinance an
         outstanding loan.

                  (b) The loan shall be for a term not to exceed five years,
         unless the loan is used to acquire any dwelling unit which within a
         reasonable time is to be used as a principal residence of the Borrower.
         A loan for the purchase of a principal residence shall be for a term
         not to exceed 20 years. The loan shall be evidenced by a note signed by
         the Borrower. The loan shall be payable in periodic installments and
         shall bear interest at a reasonable rate which shall be determined by
         the Committee on a uniform and consistent basis and set forth in the
         procedures in accordance with applicable governmental regulations.
         Payments by a Borrower who is an Employee receiving compensation from
         the Employer will be made by means of payroll deduction from the
         Borrower's compensation. If the Borrower is not receiving compensation
         from the Employer, the loan repayment shall be made in accordance with
         the terms and procedures established by the Committee. A Borrower may
         repay an outstanding loan in a single lump-sum payment before the
         scheduled due date for repayment of such loan but may not accelerate
         the payment of the loan by increasing the amount of the installments.

                  (c) In the event an installment payment is not paid on a
         scheduled due date, the Committee shall give written notice to the
         Borrower sent to his last known address. If such installment payment is
         not made within 90 days thereafter, the Committee may proceed with
         foreclosure in order to collect the full remaining loan balance or
         shall make such other arrangements with the Borrower as the Committee
         deems appropriate. Foreclosures need not be effected until occurrence
         of a distributable event under the terms of the Plan and no rights
         against the Borrower or the security shall be deemed waived by the Plan
         as a result of such delay.



                                       30


                  (d) The unpaid balance of the loan, together with interest
         thereon, shall become due and payable upon the date of distribution of
         the Account or as set forth in the applicable procedures and the
         Trustee shall first satisfy the indebtedness from the amount payable to
         the Borrower or to the Borrower's Beneficiary before making any
         payments to the Borrower or to the Beneficiary.

                  (e) Any loan to a Borrower under the Plan shall be adequately
         secured. Such security shall include a pledge of a portion of the
         Borrower's right, title and interest in the Trust Fund which shall not
         exceed 50% of the present value of the Borrower's vested Account
         balance under the Plan as determined immediately after the loan is
         extended. Such pledge shall be evidenced by the execution of a
         promissory note by the Borrower which shall grant the security interest
         and provide that, in the event of any default by the Borrower on a loan
         repayment, the Committee shall be authorized to take any and all
         appropriate lawful actions necessary to enforce collection of the
         unpaid loan. The borrower may not reduce the Account's value below the
         value of any outstanding loan balance. Thus, a loan may limit
         availability of funds for withdrawal.

                  (f) A request by a Borrower for a loan shall be made by ARU,
         internet or through a Plan representative specifying the amount of the
         loan. If a Borrower's request for a loan is approved, the Trustee shall
         make the loan in a lump-sum payment of cash to the Borrower.

                  (g) A loan to a Borrower shall be considered an investment of
         the separate Account(s) of the Borrower from which the loan is made.
         All loan repayments shall be reinvested in accordance with such
         Member's investment election for future contributions as further
         provided in Section 9.4.

                                   ARTICLE VII

                                MEMBERS' BENEFITS

         7.1 Retirement of Members on or after Retirement Date: Any Member who
terminates his Service on or after age 55 shall be vested in and entitled to
receive the entire amount of his Account. The "entire amount" in such Member's
Account at termination of employment shall include any Pre-Tax Contributions and
Employer Matching Contributions to be made at the end of a payroll period.
Payment of benefits due under this Section shall be made in accordance with
Section 8.1.

         7.2 Disability of Members: If the Committee shall find and advise the
Trustee that Service of a Member has been terminated because of physical or
mental disability, which in the judgment of the Committee, based upon advice of
competent physicians of their selection, will permanently prevent such Member
from resuming his Service with an Employer, such Member shall become entitled to
receive the entire amount of his Account. The "entire amount" in such Member's
Account shall include any Pre-Tax Contributions and Employer Matching
Contributions to be made as of the end of the payroll period in which
termination of Service occurs. Payment of benefits due under this Section shall
be made in accordance with Section 8.1.

         7.3 Death of Members: In the event of the termination of Service of any
Member by death, and after receipt by the Committee of acceptable proof of
death, his Beneficiary shall be entitled to receive the entire amount in the
Member's Account. The "entire amount" in such Member's Account shall include any
Pre-Tax Contributions and Employer Matching Contributions to be made at the end
of the payroll period in which the termination of Service occurs. Payment of
benefits due under this Section shall be made in one lump sum.

         7.4 Other Termination of Service:

                  (a) Distributions: In the event of termination of Service of
         any Member for any reason other than retirement on or after age 55,
         disability or death, a Member shall, subject to the further provisions
         of this Plan, be entitled to receive the entire amount credited to his
         After-Tax Contribution Account, Pre-Tax Contribution Account, Rollover
         Account and Prior Plan Account, plus any of his Pre-Tax Contributions
         made for the month of termination of Service, but not yet allocated. In
         addition, if the Member has completed at least five years of Service,
         he will be eligible to receive 100% of his Employer Contribution
         Account; provided, however, that a Prior Plan Member of the Jiffy Lube
         International, Inc. 401(k) Plan and Trust Agreement who has completed
         three years of Service at the time such Prior Plan Member becomes a
         Member will be eligible to receive 100% of his Employer Contribution
         Account as of the completion of such three years of Service. Upon
         termination of Service by a Member who has not completed the required
         years of Service described in the preceding sentence, the following
         schedule will apply:



                                       32

                          6                                     100%
</Table>

         If a Member terminates Service and, at the time of termination, the
         present value of the Member's vested benefit is zero, the Member will
         be deemed to have received a distribution of such vested benefit.

                  (b) Forfeitures: This Section 7.4(b) does not apply to Members
         who are fully vested at the time of termination of Service.

         If a Member receives an actual or deemed distribution pursuant to this
         Section 7.4 prior to the close of the second Plan Year following the
         Plan Year in which the Member's Service terminates, the nonvested
         portion of his Employer Contribution Account shall be treated as a
         Forfeiture and shall become available for allocation as provided in
         Section 4.8. If a Member who has received a distribution as described
         in this paragraph thereafter resumes Service under the Plan, he shall
         be entitled to have the amount of such Forfeiture reinstated to such
         Account by making a lump-sum cash payment to the Plan equal to the full
         amount of the prior distribution before the earlier of (i) five years
         after the first date on which the Member is subsequently reemployed by
         the Employer or (ii) the conclusion of five consecutive one-year Breaks
         In Service following the date of distribution.

         If a Member does not receive a distribution of his vested benefit by
         the close of the second Plan Year following the Plan Year in which his
         Service terminates, but elects to receive such a distribution before
         incurring five consecutive one-year Breaks In Service, the nonvested
         balance in the Member's Employer Contribution Account shall be credited
         to a suspense account at the time of distribution of the vested
         benefit. If such a Member is thereafter reemployed prior to incurring
         five consecutive one-year Breaks In Service, the Member's vested
         interest in the suspense account, including any gains or losses
         thereon, at any subsequent relevant time shall be an amount "X"
         determined by the following formula: X = P(AB + D) - D, where AB is the
         suspense account balance at the relevant time, P is the vested
         percentage at the relevant time and D is any amount or amounts
         previously distributed. If the Member is not reemployed before he has
         incurred five consecutive one-year Breaks In Service, his suspense
         account shall be treated as a Forfeiture and shall become available for
         allocation as described in Section 4.8.

         If a Member does not receive a distribution of his vested benefit
         before incurring five consecutive one-year Breaks In Service, the
         nonvested balance in the



                                       33


         Member's Employer Contribution Account shall then be forfeited and
         shall become available for allocation as described in Section 4.8.

         7.5 Valuation Dates Determinative of Member's Rights: In the case of
any Member whose Service is terminated for any reason, the amount to which such
Member or his Beneficiary is entitled upon such termination of Service shall be
determined as of the Valuation Date coinciding with or next following his
request for a distribution of his Account.

         7.6 Terminated After Change of Control: Notwithstanding the above
provisions of this Article VII to the contrary, in the event that any Member's
Service terminates for any reason within two years after a Change of Control has
occurred, such Member shall be fully vested and shall be entitled to receive
100% of his Employer Contribution Account upon the date of his termination of
Service.

         7.7 In-Service Distributions: No distribution or withdrawal of any
benefits under the Plan shall be permitted prior to the Member's "separation
from service, death or disability" within the meaning of Code Section 401(k) and
the regulations thereunder other than a distribution authorized under the Plan
upon the occurrence of an event described in, and made in accordance with, Code
Section 401(k)(10), any successor provision of the Code or any interpretation by
the IRS of such provisions."

                                  ARTICLE VIII

                               PAYMENT OF BENEFITS

         8.1 Payment of Benefits:

                  (a) Form of Benefits: Upon a Member's entitlement to payment
         of benefits under Section 7.1, 7.2 or 7.4, he shall file with the
         Committee his written election on such form or forms, and subject to
         such conditions, as the Committee shall provide. Except as provided
         below, payment of a Member's benefits will be made by payment in one
         lump-sum distribution. The amount which a Member, former Member or
         Beneficiary is entitled to receive from his After-Tax and/or Pre-Tax
         Contribution Accounts at any time and from time to time may be paid in
         cash or in common stock of the Company, or in any combination thereof,
         provided no discrimination in value results therefrom. The amount which
         a Member, former Member or Beneficiary is entitled to receive from his
         Employer Contribution Account at any time and from time to time shall
         be paid in shares of common stock of the Company unless such Member has
         elected to receive the vested balance in his Employer Contribution
         Account in cash.

                  (b) Notwithstanding anything herein to the contrary, a Prior
         Plan Member who was a participant in the Prior Plan or the Merged Plan
         listed below and who has a Distribution as provided under Section
         8.1(c) that is earlier than the earlier of (i) the 90th day after the
         date the participant has received a summary of material modifications
         reflecting the amendment and restatement of the Plan or January 1, 2003
         may elect to receive payment of his benefit under one of the following
         options:

                           (i) Pennzoil-Quaker State Savings Plan: In lieu of
                  receiving a lump-sum distribution as provided in paragraph (a)
                  above, a Prior Plan Member who was a Member in the
                  Pennzoil-Quaker State Savings and Investment Plan may make a
                  written request to the Committee to apply the total amount of
                  the assets transferred to the Plan as of the Effective Date to
                  the purchase of an annuity contract. Any such annuity contract
                  shall be distributed provided under Section 8.1(c). An annuity
                  contract distributed hereunder shall be purchased from an
                  insurance company or other corporation approved by the
                  Committee and shall be a single premium, immediate or deferred
                  annuity contract providing a pension for the Member with
                  payments guaranteed for a period certain, such period not to
                  exceed the actuarially estimated life expectancy of the
                  Member. Any request by a Member to receive a distribution in
                  the form of an annuity contract must be received by, or mailed
                  to, the Committee at least 30 days prior to the payment date
                  specified in Section 8.1(c); otherwise, payment will be made



                                       35


                  in a lump sum. Any annuity contract distributed by the Trustee
                  pursuant to the provisions of this Plan shall bear on the face
                  thereof the designation "Not Transferable," and such annuity
                  contract shall expressly provide that this contract may not be
                  sold, assigned, discounted or pledged as collateral for a loan
                  as or as security for the performance of an obligation or for
                  any other purpose or to any person other than this Company.

                           (ii) Pennzoil-Quaker State Corporation Thrift and
                  Stock Purchase Plan: In lieu of receiving a lump-sum
                  distribution as provided in paragraph (a) above, a Prior Plan
                  Member who was a Member in the Pennzoil-Quaker State Thrift
                  and Stock Purchase Plan (the "Thrift Plan") may elect to
                  receive his benefits, with respect to assets transferred to
                  the Plan on the Effective Date, under one of the options
                  provided below, which options are further described in the

                  (c) Timing of Benefits: The day following the date of the
         Member's termination of Service is the earliest date that payment of
         his benefits may commence and is herein referred to as such Member's
         "Distribution Date." Payment of a Member's benefits shall be made or
         commence as soon as practicable after his Distribution Date, subject to
         the Member's election to defer receipt thereof, but in any event must
         be made or commence prior to the expiration of 60 days after the Annual
         Valuation Date of the Plan Year within which such Member's Retirement
         Date occurs.

                           If the amount to which a terminated Member is
         entitled is not more than $5,000, such amount shall be paid to the
         Member as soon as practicable after his Distribution Date; if such
         amount is in excess of $5,000, the distribution shall be made only if
         the Member so consents. If such consent is withheld, distribution of
         the amount to which the terminated Member is entitled shall be made to
         such Member within 90 days after the end of the Plan Year in which
         occurs the earlier of the Member's death or his attainment of age 70.
         If a Member's termination of Service occurs after his attainment of age
         70, distribution shall be made within 90 days after the end of the Plan
         Year in which termination occurs. If such consent is withheld and the
         distribution of a Member's Account is delayed as provided immediately
         above, the amount to which such Member is otherwise entitled shall be
         segregated by the Trustee and deposited in an interest bearing account
         for ultimate distribution pursuant to the above provisions of this
         Section 8.1. Distribution of a Member's Account shall commence not
         later than the April 1 following the latter of (i) the calendar year in
         which the Member attains 70 1/2 or (ii) the calendar year in which the
         Member's employment terminates provided, however, that clause (ii) of
         this sentence shall not apply in the case of a Member who is a
         "five-percent owner" (as such term is defined in Section 416 of the
         Code) with respect to the Plan Year ending in the calendar year in
         which such Member attains age 70 1/2.

                  (d) Direct Rollovers: Notwithstanding any provision of the
         Plan to the contrary that would otherwise limit a Distributee's
         election under this Section 8.1(c), a Distributee may elect, at the
         time and in the manner prescribed by the Committee, to have any portion
         of an Eligible Rollover Distribution greater than $200 paid directly to
         an Eligible Retirement Plan specified by the Distributee



                                       38


         in a Direct Rollover. For the purposes of this section the following
         definitions shall apply:

                           (i) "Eligible Rollover Distribution" shall mean any
                  distribution of all or any portion of the balance to the
                  credit of the Distributee, except that an Eligible Rollover
                  Distribution does not include: any distribution that is one of
                  a series of substantially equal periodic payments (not less
                  frequently than annually) made for the life (or life
                  expectancy) of the Distributee or the joint lives (or joint
                  life expectancies) of the Distributee and the Distributee's
                  designated beneficiary, or for a specific period of ten years
                  or more; any distribution to the extent such distribution is
                  required under section 401(a)(9) of the Code; the portion of
                  any distribution that is not includible in gross income
                  (determined without regard to the exclusion for net unrealized
                  appreciation with respect to employer securities); and a
                  hardship withdrawal under Section 6.5 hereof.

                           (ii) "Eligible Retirement Plan" shall mean an
                  individual retirement account described in section 408(a) of
                  the Code, an individual retirement annuity Plan described in
                  section 408(b) of the Code, an annuity plan described in
                  section 403(a) of the code, or a qualified trust described in
                  section 401(a) of the Code, that accepts the Distributee's
                  Eligible Rollover Distribution. However, in the case of an
                  Eligible Rollover Distribution to the surviving spouse, an
                  Eligible Retirement Plan is an individual retirement account
                  or individual retirement annuity.

                           (iii) "Distributee" shall mean a Member or former
                  Member of the Plan. In addition, the Member's or Member's
                  surviving spouse and the Member's or former Member's spouse or
                  former spouse who is the alternate payee under a qualified
                  domestic relations order, as defined in section 414(p) of the
                  code, are Distributees with regard to the interest of the
                  spouse or former spouse.

                           (iv) "Direct Rollover" shall mean a payment by the
                  Plan to the Eligible Retirement Plan specified by the
                  Distributee.

         8.2 Presenting Claims for Benefits: Any Member or the Beneficiary of
any deceased Member may submit written application to the Committee for the
payment of any benefit asserted to be due him under the Plan. Such application
shall set forth the nature of the claim and such other information as the
Committee may reasonably request. Promptly upon the receipt of any application
required by this Section, the Committee shall determine whether or not the
Member or Beneficiary involved is entitled to a benefit hereunder and, if so,
the amount thereof and shall notify the claimant of its findings.



                                       39


                  If a claim is wholly or partially denied, the Committee shall
so notify the claimant within 90 days after receipt of the claim by the
Committee, unless special circumstances require an extension of time for
processing the claim. If such an extension of time for processing is required,
written notice of the extension shall be furnished to the claimant prior to the
end of the initial 90 day period. In no event shall such extension exceed a
period of 90 days from the end of such initial period. The extension notice
shall indicate the special circumstances requiring an extension of time and the
date by which the Committee expects to render its final decision. Notice of the
Committee's decision to deny a claim in whole or in part shall be set forth in a
manner calculated to be understood by the claimant and shall contain the
following:

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

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

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

                           (iv) an explanation of the claims review procedure
                  set forth in Section 8.3 hereof.

If notice of denial is not furnished, and if the claim is not granted within the
period of time set forth above, the claim shall be deemed denied for purposes of
proceeding to the review stage described in Section 8.3.

         8.3 Claims Review Procedure: If an application filed by a Member or
Beneficiary under Section 8.2 above shall result in a denial by the Committee of
the benefit applied for, either in whole or in part, such applicant shall have
the right, to be exercised by written application filed with the Committee
within 60 days after receipt of notice of the denial of his application or, if
no such notice has been given, within 60 days after the application is deemed
denied under Section 8.2, to request the review of his application and of his
entitlement to the benefit applied for. Such request for review may contain such
additional information and comments as the applicant may wish to present. Within
60 days after receipt of any such request for review, the Committee shall
reconsider the application for the benefit in light of such additional
information and comments as the applicant may have presented, and if the
applicant shall have so requested, shall afford the applicant or his designated
representative a hearing before the Committee. The Committee shall also permit
the applicant or his designated representative to review pertinent documents in
its possession, including copies of the Plan document and information provided
by the Employer relating to the applicant's entitlement to such benefit. The
Committee shall make a final determination with respect to the applicant's
application for review as soon as practicable, and in any event not later than
60 days after receipt of the aforesaid request for review, except that under
special circumstances, such as the necessity for holding a hearing, such 60-day
period may be extended to the extent necessary, but in no event beyond the
expiration of one hundred 120 days after receipt by the Committee of such
request for review. If such an extension of time for review is required because
of special



                                       40


circumstances, written notice of the extension shall be furnished to the
applicant prior to the commencement of the extension. Notice of such final
determination of the Committee shall be furnished to the applicant in writing,
in a manner calculated to be understood by him, and shall set forth the specific
reasons for the decision and specific references to the pertinent provisions of
the Plan upon which the decision is based. If the decision on review is not
furnished within the time period set forth above, the claim shall be deemed
denied on review.

         8.4 Disputed Benefits: If any dispute still exists between a Member or
a Beneficiary and the Committee after a review of the claim or in the event any
uncertainty shall develop as to the person to whom payment of any benefit
hereunder shall be made, the Trustee may withhold the payment of all or any part
of the benefits payable hereunder to the Member or Beneficiary until such
dispute has been resolved by a court of competent jurisdiction or settled by the
parties involved.

                                TRUST AGREEMENT;
                     INVESTMENT FUNDS; INVESTMENT DIRECTIONS

         9.1 Trust Agreement: The Company has entered into a Trust Agreement
governing the administration of the Trust established as of January 1, 2001,
under which UMB Bank, N.A. serves as Trustee, and the provisions of which are
herein incorporated by reference as fully as if set out herein.

         9.2 Investment Funds: The Trustee shall divide the Trust Fund into the
Company Stock Fund, the Newmont Mining Corporation Stock Fund, the Devon Stock
Fund and such additional Investment Funds which shall be selected and reviewed
from time to time by the Investment Committee. Each member's assets held in the
Devon Stock Fund and the Newmont Mining Corporation Stock Fund shall be further
divided into two subaccounts as provided under Section 4.10. Any cash dividends
or other income paid with respect to the Devon Fund and the Newmont Mining
Corporation Fund shall be reinvested in Pennzoil-Quaker State Company Stock. A
Member who has a Devon or a Newmont Mining Corporation Account may elect to
invest all or any part of such Accounts in any of the Investment Funds
authorized herein. Subject to such rules and procedures as may be adopted by the
Committee and communicated to Members, any Member who has a Devon or Newmont
Mining Corporation Employer Account may withdraw all of such vested account by
giving the Committee appropriate timely written notice of such withdrawal.
Notwithstanding the foregoing, Matching Contributions on behalf of each Member
who is employed by Penreco shall be invested, during the Member' employment by
Penreco, proportionately among those Investment Funds selected by the Member for
the investment of such Member's After-Tax and Pre-Tax Contribution Account.

                  Contributions shall be paid into the Fund or Funds, pursuant
to the directions of the Members given in accordance with the provisions of
Sections 9.3 and 9.4 as certified to the Trustee by the Committee. Except as
otherwise provided herein, interest, dividends and other income and all profits
and gains produced by each such Investment Fund shall be paid into such
Investment Fund, and such interest, dividends and other income or profits and
gains, without distinction between principal and income, may be invested and
reinvested but only in the property hereinabove specified for the particular
Investment Fund. As allowed in the exception provided in Section 407 of ERISA,
amounts in excess of 10% of the assets in the Trust Fund may be invested in
Company Stock. Notwithstanding any provision in this Section to the contrary,
the Committee may direct the Trustee to invest (i) Pre-Tax, or Employer Matching
Contributions in short-term fixed income investments which are acceptable to the
Trustee or in the suspense account to be maintained in each Investment Fund
during the period from the date of any such Contribution until the next
Valuation Date or (ii) all or any portion of the Trust Fund attributable to any
terminated or retired Member or attributable to any Member who is expected to
retire or to terminate his Service within one year, in one or more fixed income
investments which are acceptable to the Trustee. The fixed income investments
authorized by this Section shall include, but not be limited to, certificates of
deposit, savings accounts, or United States Treasury bills or notes.



                                       42


         9.3 Investment Directions of Members: Each Member may invest his
After-Tax and Pre-Tax Contribution Accounts, his Prior Plan Account and his
Rollover Account in increments of 1% in such Investment Funds as selected by the
Investment Committee.

                  In the event a Member fails to direct the manner of investing
his Accounts as provided herein, such Account shall be invested in the JP Morgan
Diversified Fund. All Employer Matching Contributions on behalf of each Member
shall be invested solely in shares of the common stock of the Company to be held
in the Company Stock Fund.

                  Each Member may direct that all or a part of his vested
Employer Contribution Account consisting of full shares of common stock of the
Company be liquidated and the proceeds invested among the various Investment
Funds as provided in this Section 9.3.

         9.4 Change of Investment Directions: Each Member may by ARU, internet
or through a Plan representative, in the manner prescribed by the Committee and
subject to any restrictions or conditions which may be established by the
Committee, direct the investment of his future and/or transfer of his existing
After-Tax, Pre-Tax, Employer Contributions or Rollover Account and the transfer
of assets in his Prior Plan Account, among the various Investment Funds in a
minimum increment of 1%.

         9.5 Benefits Paid Solely from Trust Fund:

         9.6 Committee Directions to Trustee: The Trustee shall make only such
distributions and payments out of the Trust Fund as may be directed by the
Committee. The Trustee shall not be required to determine or make any
investigation to determine the identity or mailing address of any person
entitled to any distributions and payments out of the Trust Fund and shall have
discharged its obligation in that respect when it shall have sent certificates
and checks or other papers by ordinary mail to such persons and addresses as may
be certified to it by the Committee.

         9.7 Authority to Designate Investment Manager: The Investment Committee
may appoint an investment manager or managers to manage (including the power to
acquire and dispose of) any assets of the Trust Fund in accordance with the
terms of the Trust Agreement and ERISA.

                                    ARTICLE X

                    ADOPTION OF PLAN BY OTHER ORGANIZATIONS;
                          SEPARATION OF THE TRUST FUND;
                     AMENDMENT AND TERMINATION OF THE PLAN;
                DISCONTINUANCE OF CONTRIBUTIONS TO THE TRUST FUND

         10.1 Adoptive Instrument: Any corporation or other organization with
employees, now in existence or hereafter formed or acquired which is not already
an Employer under this Plan and which is otherwise legally eligible, may, with
the approval of the Company by action of the Board of Directors, adopt and
become an Employer under this Plan by executing and delivering to the Company
and the Trustee an adoptive instrument specifying the classification of its
Employees who are to be eligible to participate in the Plan and by agreeing to
be bound as an Employer by all the terms of the Plan with respect to its
eligible Employees. The adoptive instrument may contain such changes and
variations in the terms of the Plan as may be acceptable to the Company. Any
such approved organizations which shall adopt this Plan shall designate the
Company as its agent to act for it in all transactions affecting the
administration of the Plan and shall designate the Committee to act for such
Employer and its Members in the same manner in which the Committee may act for
the Company and its Members hereunder. The adoptive instrument shall specify the
effective date of such adoption of the Plan and shall become, as to such
adopting Employer and its Employees, a part of this Plan. The Company may, in
its absolute discretion, terminate an adopting Employer's participation at any
time when in its judgment such adopting Employer fails or refuses to discharge
its obligations under the Plan.

                  Notwithstanding the above provisions of this Section or any
other provision of this Plan to the contrary, any employee or Member who becomes
an employee (pursuant to transfer or otherwise) of a subsidiary of a
participating Employer the outstanding common stock of which is at least 80%
owned by said participating Employer (or owned by a new subsidiary owned by a
participating Employer) will be eligible to participate in the Plan provided any
such employee or Member is paid through a payroll office located in the United
States and otherwise meets the eligibility requirements of the Plan. It shall
not be necessary for any such first-tier or second-tier subsidiary of a
participating Employer to formally adopt the Plan, such adoption to be deemed
automatic if this provision becomes operative unless (after due notice) the
board of directors or other appropriate governing authority of such subsidiary
shall direct otherwise within one year of the effective date of such adoption.

         10.2 Separation of the Trust Fund: A separation of the Trust Fund as to
the interest therein of the Members of any particular Employer may be made by an
Employer at any time. In such event, the Trustee shall set apart that portion of
the Trust Fund which shall be allocated to such Members pursuant to a valuation
and allocation of the Trust Fund made in accordance with the procedures set
forth in Sections 5.2 and 5.4, but as of the date when such separation of the
Trust Fund shall be effective. Such portion may in the Trustee's discretion be
set apart in cash or in kind out of the properties of the Trust Fund. That
portion of the Trust Fund so set apart shall continue to be held by the Trustee
as though such Employer had entered into the Trust



                                       44


Agreement as a separate trust agreement with the Trustee. Such Employer may in
such event designate a new trustee of its selection to act as trustee under such
separate trust agreement. Such Employer shall thereupon be deemed to have
adopted the Plan as its own separate plan, and shall subsequently have all such
powers of amendment or modification of such plan as are reserved herein to the
Company.

         10.3 Voluntary Separation: If any Employer shall desire to separate its
interest in the Trust Fund, it may request such a separation in a notice in
writing to the Company and the Trustee. Such separation shall then be made as of
any specified date after service of such notice, and such separation shall be
accomplished in the manner set forth in Section 10.2.

         10.4 Amendment of the Plan: The Company shall have the right to amend
or modify this Plan and (with the consent of the Trustee) the Trust Agreement at
any time and from time to time to any extent that it may deem advisable. Any
such amendment or modification shall be set out in an instrument in writing duly
authorized by the Board of Directors and executed by the Company. No such
amendment or modification shall, however, increase the duties or
responsibilities of the Trustee without its consent thereto in writing, or have
the effect of transferring to or vesting in any Employer any interest or
ownership in any properties of the Trust Fund, or of permitting the same to be
used for or diverted to purposes other than for the exclusive benefit of the
Members and their Beneficiaries. No such amendment shall decrease the Account of
any Member or shall decrease any Member's vested interest in his Account.
Notwithstanding anything herein to the contrary, the Plan or the Trust Agreement
may be amended in such manner as may be required at any time to make it conform
to the requirements of the Code or of any United States statutes with respect to
employees' trusts, or of any amendment thereto, or of any regulations or rulings
issued pursuant thereto, and no such amendment shall be considered prejudicial
to any then existing rights of any Member or his Beneficiary under the Plan.

                  No amendment shall directly or indirectly reduce a Member's
nonforfeitable vested percentage in his benefits under Section 7.4 unless each
Member having not less than three (3) years of Service is permitted to elect to
have his non-forfeitable vested percentage in his benefits under Section 7.4
computed under the provisions of Section 7.4 without regard to the amendment.
Such election shall be available during an election period which shall begin on
the date such amendment is adopted and shall end on the latest of (i) the date
sixty (60) days after such amendment is adopted, (ii) the date sixty (60) days
after such amendment is effected, or (iii) the date sixty (60) days after such
Member is issued written notice of the amendment by the Administrative Committee
or the Employer.

         10.5 Acceptance or Rejection of Amendment by Employers: The Company
shall promptly deliver to each other Employer any amendment to this Plan or the
Trust Agreement. Each such Employer will be deemed to have consented to such
amendment unless it notifies the Company and the Trustee in writing within 30
days after receipt of the amendment that it does not consent thereto, and
requests a separation of its interest in the Trust Fund in accordance with the
provisions of Section 10.2, as of the first day of the month following such
written notification to the Company and the Trustee.



                                       45


         10.6 Termination of the Plan: A termination of the Plan as to any
particular Employer (and only as to any such particular Employer) shall occur
under the following circumstances:

                  (a) The Plan may be terminated by the delivery to the Trustee
         of an instrument in writing approved and authorized by the board of
         directors of such Employer. In such event, termination of the Plan
         shall be effective as of any subsequent date specified in such
         instrument.

                  (b) Except as otherwise provided in Section 10.10, the Plan
         shall terminate effective at the expiration of 60 days following the
         merger into another corporation or dissolution of any Employer, or
         following any final legal adjudication of any Employer as a bankrupt or
         an insolvent, unless within such time a successor organization approved
         by the Company shall deliver to the Trustee a written instrument
         certifying that such organization has (i) become the Employer of more
         than 50% of those Employees of such Employer who are then Members under
         this Plan and (ii) adopted the Plan as to its Employees. In any such
         event the interest in the Plan of any Member whose employment may not
         be continued by the successor shall be fully vested as of the date of
         termination of his Service, and shall be payable in cash or in kind
         within 6 months from the date of termination of his Service.

                  (c) In the event of termination of the Plan as herein
         provided, any amounts attributable to a Member's Pre-Tax Contributions
         may not be distributed earlier than upon one of the following events:

                           (i) The Member's retirement, death, disability or
                  separation from Service;

                           (ii) The termination of the Plan without
                  establishment or maintenance of another defined contribution
                  Plan (other than an ESOP or SEP);

                           (iii) The Member's attainment of age 59 1/2, or the
                  Member's hardship;

                           (iv) The sale or other disposition by an Employer to
                  an unrelated corporation of substantially all of the assets
                  used in a trade or business, but only with respect to
                  Employees who continue employment with the acquiring
                  corporation and the acquiring corporation does not maintain
                  the Plan after the disposition; and

                           (v) The sale or other disposition by an Employer of
                  its interest in a subsidiary to an unrelated entity but only
                  with respect to Employees who continue employment with the
                  subsidiary and



                                       46


                  the acquiring entity does not maintain the Plan after the
                  disposition.

                           A distribution may be made pursuant to the provisions
         of paragraphs (iv) and (v) of this Section 10.6(c) only if the Employer
         continues to maintain the plan after the disposition. A distribution
         may be made pursuant to paragraphs (ii), (iv) and (v) of this Section
         10.6(c) only if the distribution is a lump-sum distribution.

         10.7 Liquidation and Distribution of Trust Fund Upon Termination: In
the event a complete or partial termination of the Plan in respect of any
Employer shall occur, a separation of the Trust Fund in respect of the affected
Members of such Employer shall be made as of the effective date of such
termination of the Plan in accordance with the procedure set forth in Section
10.2. Following separation of the Trust Fund in respect of the Members of any
Employer as to whom the Plan has been terminated, the assets and properties of
the Trust Fund so set apart, other than common stock of the Company, shall be
reduced to cash as soon as may be expeditious under the circumstances. Any
administrative costs or expenses incurred incident to the final liquidation of
such separate trust funds shall be paid by the Employer, except that in the case
of bankruptcy or insolvency of such Employer any such costs shall be charged
against the Trust Fund. Following such partial reduction of such Trust Fund to
cash, the Accounts of the Members shall then be valued as provided in Sections
5.2 and 5.4 and shall be fully vested, whereupon each such Member shall become
entitled to receive the entire amount in his Account in cash and/or common stock
of Pennzoil Company, as directed by the Committee. The terminating Employer
shall promptly advise the appropriate District Director of the Internal Revenue
Service of such complete or partial termination. Any distribution due to the
termination of the Plan will be made in accordance with the requirements of Code
Sections 401(a)(11), 411(d)(6) and 417.

         10.8 Effect of Termination or Discontinuance of Contributions: If any
Employer shall terminate or partially terminate the Plan as to its Employees,
then all amounts credited to the Accounts of the Members of such Employer with
respect to whom the Plan has terminated shall become fully vested and
non-forfeitable. If any Employer shall completely discontinue its Contributions
to the Trust Fund or suspend its Contributions to the Trust Fund under such
circumstances as to constitute a complete discontinuance of Contributions within
the meaning of Section 1.401-6(c) of the regulations under the Code, then all
amounts credited to the Accounts of the Members of such Employer shall become
fully vested and non-forfeitable, and throughout any such period of
discontinuance of Contributions by an Employer all other provisions of the Plan
shall continue in full force and effect with respect to such Employer other than
the provisions for Contributions by such Employer.

         10.9 Merger of Plan with Another Plan: In the event of any merger or
consolidation of the Plan with, or transfer in whole or in part of the assets
and liabilities of the Trust Fund to another trust fund held under, any other
plan of deferred compensation maintained or to be established for the benefit of
all or some of the Members of this Plan, the assets of the Trust Fund applicable
to such Members shall be transferred to the other trust fund only if:



                                       47


                  (a) Each Member would (if either this Plan or the other Plan
         then terminated) receive a benefit immediately after the merger,
         consolidation or transfer which is equal to or greater than the benefit
         he would have been entitled to receive immediately before the merger,
         consolidation or transfer (if this Plan had then terminated);

                  (b) Resolutions of the board of directors of the Employer
         under this Plan, or of any new or successor employer of the affected
         Members, shall authorize such transfer of assets, and, in the case of
         the new or successor employer of the affected Members, its resolutions
         shall include an assumption of liabilities with respect to such
         Members' inclusion in the new employer's Plan; and

                  (c) Such other plan and trust are qualified under Sections
         401(a) and 501(a) of the Code.

         10.10 Consolidation or Merger with Another Employer: Notwithstanding
any provision of this Article X to the contrary, upon the consolidation or
merger of two or more Employers under this Plan with each other, the surviving
Employer or organization shall automatically succeed to all the rights and
duties under the Plan and Trust of the Employers involved, and their shares of
the Trust Fund shall, subject to the provisions of Section 10.9, be merged and
thereafter be allocable to the surviving Employer or organization for its
Members and their Beneficiaries.



                                       48


                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

         11.1 Terms of Employment: The adoption and maintenance of the
provisions of this Plan shall not be deemed to constitute a contract between any
Employer and Employee, or to be a consideration for, or an inducement or
condition of, the employment of any person. Nothing herein contained shall be
deemed to give to any Employee the right to be retained in the employ of an
Employer or to interfere with the right of an Employer to discharge an Employee
at any time, nor shall it be deemed to give to an Employer the right to require
any Employee to remain in its employ, nor shall it interfere with any Employee's
right to terminate his employment at any time.

         11.2 Controlling Law: Subject to the provisions of ERISA, this Plan
shall be construed, regulated and administered under the laws of the State of
Texas.

         11.3 Invalidity of Particular Provisions: In the event any provision of
this Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining provisions of this Plan but shall be
fully severable, and this Plan shall be construed and enforced as if said
illegal or invalid provisions had never been inserted herein.

         11.4 Non-Alienation of Benefits: Except as otherwise provided below and
with respect to certain judgments and settlements pursuant to Section 401(a)(13)
of the Code, no benefit which shall be payable out of the Trust Fund to any
person (including a Member or beneficiary) shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or
change, and any attempt to anticipate, alienate, sell, transfer assign, pledge,
encumber or charge the same shall be voided and no such benefit shall in any
manner be liable for, or subject to attachment or legal process for or against
such person, and the same shall not be recognized by the Trustee, except to the
extent as may be required by law.

                  This provision shall not apply to a "qualified domestic
relations order" defined in Code Section 414(p), and those other domestic
relations orders permitted to be so treated by the Committee under the
provisions of the Retirement Equity Act of 1984. The Committee shall establish a
written procedure to determine the qualified status of domestic relations orders
and to administer distributions under such qualified orders. Further, to the
extent provided under a "qualified domestic relations order," a former spouse of
a Member shall be treated as the spouse or surviving spouse for all purposes of
the Plan. If, from and after April 1, 1990, the Committee receives a qualified
domestic relations order with respect to a Member, the Committee may authorize
the immediate distribution of the amount assigned to the Member's former spouse
pursuant to such order, to the extent vested and permitted by law, from the
Member's Accounts.

         11.5 Payments in Satisfaction of Claims of Members: Any payment or
distribution to any Member or his legal representative or any Beneficiary in
accordance with the provisions of this Plan shall be in full satisfaction of all
claims under the Plan against the Trust Fund, the Trustee and the Employer. The
Trustee may require that any distributee execute and deliver to



                                       49


the Trustee a receipt and a full and complete release as a condition precedent
to any payment or distribution under the Plan.

         11.6 Payments Due Minors and Incompetents: If the Committee determines
that any person to whom a payment is due hereunder is a minor or is incompetent
by reason of physical or mental disability, the Committee shall have the power
to cause the payments becoming due such person to be made to another for the
benefit of such minor or incompetent, without the Committee or the Trustee being
responsible to see to the application of such payment. To the extent permitted
by ERISA, payments made pursuant to such power shall operate as a complete
discharge of the Committee, the Trustee and the Employer.

         11.7 Impossibility of Diversion of Trust Fund: Notwithstanding any
provision herein to the contrary, no part of the corpus or the income of the
Trust Fund shall ever be used for or diverted to purposes other than for the
exclusive benefit of the Members or their Beneficiaries or for the payment of
expenses of the Plan. No part of the Trust Fund shall ever directly or
indirectly revert to any Employer.

         11.8 Evidence Furnished Conclusive: The Employer, the Committee and any
person involved in the administration of the Plan or management of the Trust
Fund shall be entitled to reply upon any certification, statement or
representation made or evidence furnished by a Member or Beneficiary with
respect to facts required to be determined under any of the provisions of the
Plan, and shall not be liable on account of the payment of any monies or the
doing of any act or failure to act in reliance thereon. Any such certification,
statement, representation or evidence, upon being duly made or furnished, shall
be conclusively binding upon such Member or Beneficiary but not upon the
Employer or the Committee or any other person involved in the administration of
the Plan or management of the Trust Fund. Nothing herein contained shall be
construed to prevent any of such parties from contesting any such certification,
statement, representation or evidence or to relieve the Member or Beneficiary
from the duty of submitting satisfactory proof of such fact.

         11.9 Copy Available to Members: A copy of the Plan, and of any and all
future amendments thereto, shall be provided to the Committee and shall be
available to Members and, in the event of the death of a Member, to his
Beneficiary, for inspection at the offices of his Employer during the regular
office hours of the Employer.

         11.10 Unclaimed Benefits: If at, after or during the time when a
benefit hereunder is payable to any Member, Beneficiary or other distributee,
the Committee, upon request of the Trustee, or at its own instance, shall mail
by registered or certified mail to such Member, Beneficiary or other distributee
at his last known address a written demand for his then address or for
satisfactory evidence of his continued life, or both, and if such Member,
Beneficiary or distributee shall fail to furnish the same to the Committee
within two years from the mailing of such demand, then the Committee may, in its
sole discretion, determine that such Member, Beneficiary or other distributee
has forfeited his right to such benefit and may declare such benefit, or any
unpaid portion thereof, terminated as if the death of the distributee (with no
surviving Beneficiary) had occurred on the date of the last payment made
thereon, or on the date such Member, Beneficiary or distributee first became
entitled to receive benefit payments,



                                       50


whichever is later; provided, however, that such forfeited benefit shall be
reinstated if a claim for the same is made by the Member, Beneficiary or other
distributee at any time thereafter. Such reinstatement shall be made out of the
Forfeitures for the Plan Year during which such claim was filed with the
Committee (as provided in Section 4.8); and, if Forfeitures for the Plan Year
are insufficient to reinstate such amounts, the Employer shall make the Minimum
Contribution required under Section 4.2 hereof.

         11.11 Headings for Convenience Only: The headings and subheadings
herein are inserted for convenience of reference only and are not to be used in
construing this instrument or any provision thereof.

         11.12 Successors and Assigns: This agreement shall bind and inure to
the benefit of the successors and assigns of the Employers.



                                       51


                                   ARTICLE XII

                           TOP-HEAVY PLAN REQUIREMENTS

         12.1 General Rule: For any Plan Year for which this Plan is a Top-Heavy
Plan, as defined in Section 12.8, despite any other provisions of this Plan to
the contrary, this Plan shall be subject to the provisions of this Article XII.

         12.2 Vesting Provisions: Each Member who has completed an Hour of
Service after the Plan becomes top-heavy and while the Plan is top-heavy and who
has completed the Vesting Service specified in the following table shall be
vested in his account under this Plan at least as rapidly as is provided in the
following schedule; except that the vesting provision set forth in Section 7.4
shall be used at any time in which it provides for more rapid vesting:


<Table>
<Caption>
                Years of Service                               Vested Percent
                ----------------                               --------------
                                                            
                Less than 2 years                                       0%
                2 but less than 3 years                                25%
                3 but less than 4 years                                40%
                4 but less than 5 years                                60%
                5 but less than 6 years                                80%
                6 years or more                                       100%
</Table>

If an account becomes vested by reason of the application of the preceding
schedule, it may not thereafter be forfeited by reason of re-employment after
retirement pursuant to a suspension of benefits provision, by reason of
withdrawal of any mandatory employee contributions to which employer
contributions were keyed, or for any other reason. If the Plan subsequently
ceases to be top-heavy, the preceding schedule shall continue to apply with
respect to any Member who had at least three years of service (as defined in
Treasury Regulation Section 1.411(a)-8T(b)(3)) as of the close of the last year
that the Plan was top-heavy. For all other Members, the vested percentage
provided in the preceding schedule prior to the date the Plan ceases to be
top-heavy shall not be reduced.

         12.3 Minimum Contribution Percentage: Each Member who is (i) a Non-Key
Employee, as defined in Section 12.8 and (ii) employed on the last day of the
Plan Year will be entitled to have contributions and forfeitures (if applicable)
allocated to his account of not less than 3% (the "Minimum Contribution
Percentage") of the Member's Compensation. This minimum allocation percentage
shall be provided without taking pre-tax contributions into account. A Non-Key
Employee may not fail to receive a Minimum Contribution Percentage because of a
failure to receive a specified minimum amount of compensation or a failure to
make mandatory employee or elective contributions. This Minimum Contribution
Percentage will be reduced for any Plan Year to the percentage at which
contributions (including forfeitures if applicable) are made or are required to
be made under the Plan for the Plan Year for the Key Employee for whom such
percentage is the highest for such Plan Year. For this purpose, the percentage
with respect to a Key Employee will be determined by dividing the contributions



                                       52


(including forfeitures if applicable) made for such Key Employee by his total
compensation (as defined in Section 415 of the Code) not in excess of $170,000
for the Plan Year. Such amount will be adjusted in the same manner as the amount
set forth in Section 12.4 below.

                  Contributions considered under the first paragraph of this
Section 12.3 will include Employer contributions under this Plan and under all
other defined contribution plans required to be included in an Aggregation Group
(as defined in Section 12.8 below), but will not include Employer contributions
under any plan required to be included in such aggregation group if the plan
enables a defined benefit plan required to be included in such group to meet the
requirements of the Code prohibiting discrimination as to contributions in favor
of employees who are officers, shareholders, or the highly compensated or
prescribing the minimum participation standards. If the highest rate allocated
to a Key Employee for a year in which the Plan is top heavy is less than 3%,
amounts contributed as a result of a salary reduction agreement must be included
in determining contributions made on behalf of Key Employees.

                  Contributions considered under this Section will not include
any contributions under the Social Security Act or any other federal or state
law.

         12.4 Limitation on Compensation: The annual compensation of a Member
taken into account under this Article XII and under Article I for purposes of
computing benefits under this Plan shall not exceed $170,000. From and after
January 1, 1994, the annual Compensation of a Member taken into account under
this Article XII shall not exceed $170,000, or such other amount as determined
by the Secretary of the Treasury or his delegate. Such amount shall be adjusted
automatically for each Plan Year to the amount prescribed by the Secretary of
the Treasury or his delegate pursuant to regulations for the calendar year in
which such Plan Year commences.

         12.5 Coordination With Other Plans: In the event that another defined
contribution or defined benefit plan maintained by a Considered Company provides
contributions or benefits on behalf of Members in this Plan, such other plan
shall be treated as a part of this Plan pursuant to principles prescribed by
applicable U.S. Treasury Regulations or IRS rulings to determine whether this
Plan satisfies the requirements of Sections 12.3, 12.4 and 12.5 and to avoid
inappropriate omissions or inappropriate duplication. If a Member is covered
both by a top-heavy defined benefit plan and a top-heavy defined contribution
plan, a comparability analysis (as prescribed by Revenue Ruling 81-202 or any
successor ruling) shall be performed in order to establish that the plans are
providing benefits at least equal to the defined benefit minimum. Such
determination shall be made upon the advice of counsel by the Committee which
shall, if necessary, cause benefits or contributions to be made sufficient.

         12.6 Distributions to Certain Key Employees: Notwithstanding any other
provision of this Plan to the contrary, the entire interest in this Plan of each
Member who is a 5% owner (as described in Section 416(i)(1)(A) of the Code
determined with respect to the Plan Year ending in the calendar year in which
such individual attains age 70 1/2) shall be distributed to such Member not
later than the first day of April following the calendar year in which such
individual attains age 70 1/2.



                                       53


         12.7 Determination of Top-Heavy Status: The Plan will be a Top-Heavy
Plan for any Plan Year if, as of the Determination Date, the aggregate of the
accounts under the Plan (determined as of the Valuation Date) for Members
(including former Members) who are Key Employees exceeds 60% of the aggregate of
the accounts of all Members, excluding former Key Employees, or if this Plan is
required to be in an Aggregation Group, any such Plan Year in which such Group
is a Top-Heavy Group. In determining Top-Heavy status, if an individual has not
performed one Hour of Service for any Considered Company at any time during the
five year period ending on the Determination Date, any accrued benefit for such
individual and the aggregate accounts of such individual shall not be taken into
account.

                  For purposes of this Section, the capitalized words have the
following meanings:

                  (a) Aggregation Group means the group of plans, if any, that
         includes both the group of plans required to be aggregated and the
         group of plans permitted to be aggregated. The group of plans required
         to be aggregated (the "required aggregation group") includes:

                           (i) Each plan of a Considered Company in which a Key
                  Employee is a participant in the Plan Year containing the
                  Determination Date, or any of the four preceding Plan Years;
                  and

                           (ii) Each other plan, including collectively
                  bargained plans, of a Considered Company which, during this
                  period, enables a plan in which a Key Employee is a
                  participant to meet the requirements of Section 401(a)(4) or
                  410 of the Code.

                           The group of plans that are permitted to be
         aggregated (the "permissive aggregation group") includes the required
         aggregation group plus one or more plans of a Considered Company that
         is not part of the required aggregation group and that the Considered
         Company certifies as a plan within the permissive aggregation group.
         Such plan or plans may be added to the permissive aggregation group
         only if, after the addition, the aggregation group as a whole continues
         to satisfy the requirements of Sections 401(a)(4) and 410 of the Code.

                  (b) "Determination Date" means for any Plan Year the last day
         of the immediately preceding Plan Year.

                  (c) "Key Employee" means any Employee or former Employee under
         this Plan who, at any time during the Plan Year in question or during
         any of the four preceding Plan Years, is or was one of the following:

                           (i) An officer of a Considered Company having an
                  annual compensation greater than 50% of the amount in effect
                  under Section 415(b)(1)(A) of the Code for any such Plan Year.
                  Whether an individual is an officer shall be determined by the
                  Considered Company on the basis of all the facts and



                                       54


                  circumstances, such as an individual's authority, duties, and
                  term of office, not on the mere fact that the individual has
                  the title of an officer. For any such Plan Year, officers
                  considered to be Key Employees will be no more than the fewer
                  of:

                                    (A) 50 employees; or

                                    (B) 10% of the employees or, if greater than
                           10%, 3 employees.

                           For this purpose, the highest paid officers shall be
         selected.

                           (ii) One of the ten Employees owning (or considered
                  as owning, within the meaning of the constructive ownership
                  rules of Section 416(i)(1)(B) of the Code) the largest
                  interests in the Considered Company. An employee who has some
                  ownership interest is considered to be one of the top ten
                  owners unless at least ten other employees own a greater
                  interest than that employee. However, an employee will not be
                  considered a top 10 owner for a Plan Year if the employee
                  earns less than the maximum dollar limitation on annual
                  additions to a Member's account in a defined contribution plan
                  under the Code, as in effect for the calendar year in which
                  the Determination Date falls.

                           (iii) Any person who owns (or is considered as
                  owning, within the meaning of the constructive ownership rules
                  of Section 416(i)(1)(B) of the Code) more than 5% of the
                  outstanding stock of a Considered Company or stock possessing
                  more than 5% of the combined voting power of all stock of the
                  Considered Company.

                           (iv) Any person who has an annual compensation from
                  the Considered Company of more than $170,000 and who owns (or
                  is considered as owning within the meaning of the constructive
                  ownership rules of Section 416(i)(1)(B) of the Code) more than
                  1% of the outstanding stock of the Considered Company or stock
                  possessing more than 1% of the total combined voting power of
                  all stock of the Considered Company. For purposes of this
                  subsection, compensation means all items includable as
                  compensation for purpose of applying the limitations on annual
                  additions to a Member's account in a defined contribution plan
                  and the maximum benefit payable under a defined benefit plan
                  under the Code.

         For purposes of this subsection (c), a Beneficiary of a Key Employee
         shall be treated as a Key Employee. For purposes of parts (iii) and
         (iv), each Considered



                                       55


         Company is treated separately in determining ownership percentages; but
         all such Considered Companies shall be considered a single employer in
         determining the amount of compensation.

                  (d) "Non-Key Employee" means any employee (and any Beneficiary
         of an employee) who is not a Key Employee.

                  (e) "Top-Heavy Group" means the Aggregation Group, if as of
         the applicable Determination Date, the sum of the present value of the
         cumulative accrued benefits for Key Employees under all defined benefit
         plans included in the Aggregation Group plus the aggregate of the
         accounts of Key Employees under all defined contribution plans included
         in the Aggregation Group exceeds 60% of the sum of the present value of
         the cumulative accrued benefits for all employees, excluding former Key
         Employees as provided in paragraph (i) below, under all such defined
         benefit plans plus the aggregate accounts for all employees, excluding
         former Key Employees as provided in paragraph (i) below, under all such
         defined contribution plans. In determining Top-Heavy status, if an
         individual has not performed one Hour of Service for any Considered
         Company at any time during the five year period ending on the
         Determination Date, any accrued benefit for such individual and the
         aggregate accounts of such individual shall not be taken into account.
         If the Aggregation Group that is a Top-Heavy Group is a required
         aggregation group, each plan in the group will be a Top-Heavy Plan. If
         the Aggregation Group that is a Top-Heavy Group is a permissive
         aggregation group, only those plans that are part of the required
         aggregation group will be treated as Top-Heavy Plans. If the
         Aggregation Group is not a Top-Heavy Group, no plan within such group
         will be a Top-Heavy Plan.

         In determining whether this Plan constitutes a Top-Heavy Plan, the
         Committee (or its agent) will make the following adjustments:

                  (f) When more than one plan is aggregated, the Committee shall
         determine separately for each plan as of each plan's Determination Date
         the present value of the accrued benefits (for this purpose using the
         actuarial assumptions set forth in the applicable plan or account
         balance). The results shall then be aggregated by adding the results of
         each plan as of the Determination Dates for such plans that fall within
         the same calendar year.

                  (g) In determining the present value of the cumulative accrued
         benefit (for this purpose using the actuarial assumptions set forth in
         the applicable pension plan) or the amount of the account of any
         employee, such present value or account will include the amount in
         dollar value of the aggregate distributions made to such employee under
         the applicable plan during the five year period ending on the
         Determination Date unless reflected in the value of the accrued benefit
         or account balance as of the most recent Valuation Date. The amounts
         will include distributions to employees representing the entire amount
         credited to their accounts under the applicable plan.



                                       56


                  (h) Further, in making such determination, such present value
         or such account shall include any rollover contribution (or similar
         transfer), as follows:

                           (i) If the rollover contribution (or similar
                  transfer) is initiated by the employee and made to or from a
                  plan maintained by another Considered Company, the plan
                  providing the distribution shall include such distribution in
                  the present value of such account; the plan accepting the
                  distribution shall not include such distribution in the
                  present value of such account unless the plan accepted it
                  before December 31, 1983.

                           (ii) If the rollover contribution (or similar
                  transfer) is not initiated by the employee or made from a plan
                  maintained by another Considered Company, the plan accepting
                  the distribution shall include such distribution in the
                  present value of such account, whether the plan accepted the
                  distribution before or after December 31, 1983; the plan
                  making the distribution shall not include the distribution in
                  the present value of such account.

                  (i) In any case where an individual is a Non-Key Employee with
         respect to an applicable plan but was a Key Employee with respect to
         such plan for any prior Plan Year, any accrued benefit and any account
         of such employee shall be altogether disregarded. For this purpose, to
         the extent that a Key Employee is deemed to be a Key Employee if he or
         she met the definition of Key Employee within any of the four preceding
         Plan Years, this provision shall apply following the end of such period
         of time. (j) "Valuation Date" means for purposes for determining the
         present value of an accrued benefit as of the Determination Date the
         date determined as of the most recent valuation date which is within a
         12-month period ending on the Determination Date. For the first plan
         year of a plan, the accrued benefit for a current employee shall be
         determined either (i) as if the individual terminated service as of the
         Determination Date or (ii) as if the individual terminated service as
         of the valuation date, but taking into account the estimated accrued
         benefit as of the Determination Date. The Valuation Date shall be
         determined in accordance with the principles set forth in Q.&A. T-25 of
         Treasury Regulations Section 1.416-1.

                  (k) For purposes of this Article, "Compensation" shall have
         the meaning given to it in Section 5.3(IV)(5) of the Plan.



                                       57


                                  ARTICLE XIII

                            TESTING OF CONTRIBUTIONS

         13.1 Definitions: For purposes of this Article XIII, the capitalized
words have the following meanings:

                  (a) "After-Tax Contributions" shall mean the amounts
         contributed to the Trust Fund pursuant to Section 4.3.

                  (b) "Compensation" shall mean the Employee's total
         Compensation, as defined in Section 414(s) of the Code, for services
         rendered to an Employer during the Plan Year, including the Employee's
         Pre-Tax Contributions for the Plan Year and any amounts not currently
         included in the Employee's gross income by reason of the application of
         Section 125 of the Code. Such Compensation shall be limited to $170,000
         (as adjusted by the Secretary of the Treasury or his delegate).

                  (c) "Employer Matching Contributions" shall mean the amounts
         contributed to the Trust Fund by the Employer pursuant to Section 4.2.

                  (d) "Highly Compensated Employee" shall mean any Employee and
         any employee of an Affiliate who is a highly compensated employee under
         Section 414(q) of the Code, including any Employee and any employee of
         an Affiliate who:

                           (i) was a 5% owner during the current Plan Year or
                  prior Plan Year; or

                           (ii) received Compensation during the Plan Year (as
                  defined in Section 5.3(IV)(5) in excess of $85,000 or such
                  other dollar amount as may be prescribed by the Secretary of
                  the Treasury or his delegate and, if elected by the Employer,
                  was in the "top-paid group" (the top 20% of payroll) for the
                  Plan Year, excluding Employees described in Code Section
                  414(p)(8).

                           In determining an Employee's status as a Highly
         Compensated Employee within the meaning of Section 414(q), the entities
         set forth in Treasury Regulation Section 1.414(q)-1T Q&A-6(a)(1)
         through (4) must be taken into account as a single employer.

                           A former Employee shall be treated as a Highly
         Compensated Employee if (1) such former Employee was a Highly
         Compensated Employee when he separated from Service, or (2) such former
         Employee was a Highly Compensated Employee in Service at any time after
         attaining age 55.



                                       58


                  (e) "Pre-Tax Contributions" shall mean the amounts contributed
         to the Trust Fund out of a Member's Compensation pursuant to Section
         4.1.

                  (f) "Qualified Matching Contributions" shall mean Employer
         Matching Contributions which are allocated to eligible Members within a
         Plan Year in which the Plan failed to satisfy the Actual Deferral
         Percentage Limits set forth in Section 13.3, which satisfy the
         nonforfeitability and distribution requirements for elective
         contributions when they are contributed to the Plan in accordance with
         Treasury Regulation 1.401(k)-1(g)(13)(iii), which satisfy the
         requirements of Treasury Regulation 1.401(k)-1(b)(5) and which may be
         used in the determination of Actual Deferral Percentages to help in
         satisfying the limits of Section 13.3. Qualified Matching Contributions
         which are used in applying the Actual Deferral Percentage test may not
         be used in applying the Contribution Percentage test.

         13.2 Actual Deferral Percentage: The Actual Deferral Percentage for a
specified group of Employees for a Plan Year shall be the average of the ratios
(calculated separately for each Employee in such group) of:

                  (a) The amount of Pre-Tax Contributions actually paid to the
         Plan on behalf of each such Employee for such Plan Year which relate to
         Compensation that either would have been received by the Employee in
         such Plan Year (but for the deferral election) or are attributable to
         services performed by the Employee in the Plan Year and would have been
         received by the Employee within 2 1/2 months after the close of the
         Plan Year (but for the deferral election), over

                  (b) The Employee's Compensation for such Plan Year.

                           To the extent permitted by the Code and applicable
         regulations, the Employer may elect to take into account, in computing
         the Actual Deferral Percentage all or part of the Qualified Matching
         Contributions made under this Plan or any other Plan of the Employer.

                           The individual ratios and Actual Deferral Percentages
         shall be calculated to the nearest 1/100 of 1% of an Employee's
         Compensation. An eligible Employee for the purpose of computing the
         Actual Deferral Percentage is defined in Code Regulation Section
         1.401(k)-1(g)(4). The Actual Deferral Percentage of an eligible
         Employee who makes no Pre-Tax Contributions and receives no
         Supplemental Contributions is zero.

         The Plan uses the Actual Deferred Percentage for Members who are Highly
         Compensated Employees and non-Highly Compensated Employees for the
         prior Plan Year in performing the nondiscrimination testing required
         under this Section for the current Plan Year.



                                       59


         13.3 Actual Deferral Percentage Limits: The Actual Deferral Percentage
for the eligible Highly Compensated Employees for any Plan Year shall not exceed
the greater of (a) or (b), as follows:

                  (a) The Actual Deferral Percentage of Compensation for the
         eligible non-Highly Compensated Employees times 1.25; or

                  (b) The lesser of (i) the Actual Deferral Percentage of
         Compensation for the eligible non-Highly Compensated Employees times
         2.0 or (ii) the Actual Deferral Percentage of Compensation for the
         eligible non-Highly Compensated Employees plus two percentage points or
         such lesser amount as the Secretary of the Treasury shall prescribe to
         prevent the multiple use of this alternative limitation with respect to
         any Highly Compensated Employee.

                           The Actual Deferral Percentage for any Highly
         Compensated Employee who is eligible to have deferred contributions
         allocated to his account under one or more plans described in Section
         401(k) of the Code that are maintained by an Employer or an Affiliate
         in addition to this Plan shall be determined as if all such
         contributions were made to this Plan. For purposes of determining
         whether the Actual Deferral Percentage limits of Section 13.3 are
         satisfied, all Pre-Tax Contributions that are made under two or more
         plans that are aggregated for purposes of Code Section 401(a)(4) or
         410(b) (other than Code Section 410(b)(2)(A)(ii)) are to be treated as
         made under a single plan and if two or more plans are permissively
         aggregated for purposes of Code Section 401(k) the aggregated plans
         must also satisfy Code Sections 401(a)(4) and 410(b) as though they
         were a single plan. For purposes of determining whether the Actual
         Deferral Percentage limits of Section 13.3 are satisfied, all Pre-Tax
         Contributions that are made under two or more plans that are aggregated
         for purpose of Code Section 401(a)(4) or 410(b) (other than Code
         Section 410(b)(2)(A)(ii)) are to be treated as made under a single
         plan, and if two or more plans are permissively aggregated for purposes
         of Code Section 401(k), the aggregated plans must also satisfy Code
         Sections 401(a)(4) and 410(b) as though they were a single plan.

                           An eligible Employee for purposes of computing the
         actual deferral percentage is defined in Regulation Section
         1.401(k)-1(g)(4).

         13.4 Reduction of Pre-Tax Contribution Rates by Leveling Method: If on
the basis of the Pre-Tax Contribution rates elected by Members for any Plan
Year, the Committee determines, in its sole discretion, that neither of the
tests contained in (a) or (b) of Section 13.3 will be satisfied, the Committee
may reduce the Pre-Tax Contribution rate of any Member who is among the eligible
Highly Compensated Employees to the extent necessary to reduce the overall
Actual Deferral Percentage for eligible Highly Compensated Employees to a level
which will satisfy either (a) or (b) of Section 13.3. The reductions in Pre-Tax
Contribution rates shall be made in a manner so that the Actual Deferral
Percentage of the affected Members who elected the highest Actual Deferral
Percentage shall be first lowered to the level of the affected Members who
elected the next to the highest Actual Deferral Percentage as provided in
Section 13.6. If



                                       60


further overall reductions are required to achieve compliance with (a) or (b) of
Section 13.3, both of the above-described groups of Members will be lowered as
provided in Section 13.6 to the level of Members with the next highest Actual
Deferral Percentage, and so on, until sufficient total reductions in Pre-Tax
Contribution rates have occurred to achieve compliance with (a) or (b) of
Section 13.3. The Committee may, in accordance with such uniform rules and
procedures as it may in its discretion prescribe, permit a Member whose Pre-Tax
Contributions are reduced under this paragraph, to elect to recharacterize a
like amount as After-Tax Contributions. Notwithstanding the foregoing, however,
recharacterized Pre-Tax Contributions shall, for all other purposes of this Plan
except this Article XIII, continue to be treated as Pre-Tax Contributions and
not as After-Tax Contributions. The Committee may also allow the Member to make
an election to reduce his Pre-Tax Contribution rate for the remainder of any
Plan Year in which the Committee determines, based on the Pre-Tax Contribution
rates elected by Members, that neither of the tests contained in Section 13.3
will be satisfied, and to receive a distribution as of the end of the Plan Year
of any such excess Pre-Tax Contributions.

         13.5 Increase in Pre-Tax Contribution Rates: If a Member's Pre-Tax
Contribution rate is reduced below the level necessary to satisfy either (a) or
(b) of Section 13.3 for the Plan Year, such Member may be eligible to increase
his Pre-Tax Contribution rate for the remainder of the Plan Year to a level not
in excess of that level which will satisfy the greater of (a) or (b) of Section
13.3. Such an increase in the Pre-Tax Contribution rate shall be made by Members
on a uniform and non-discriminatory basis, pursuant to such rules and procedures
as the Committee may prescribe.

         13.6 Excess Pre-Tax Contributions: As soon as possible following the
end of the Plan Year, the Committee shall determine whether either of the tests
contained in Section 13.3 were satisfied as of the end of the Plan Year, and any
excess Pre-Tax Contributions, plus any income and minus any loss attributable
thereto, of those Members who are among the Highly Compensated Employees shall
be recharacterized or distributed and shall be considered as taxable income to
such Members in the manner provided below based on the amount of Pre-Tax
Contributions. Any amounts recharacterized as After-Tax Contributions shall be
transferred to the comparable After-Tax Contribution Accounts of such Members as
of the end of such Plan Year; provided, however, that such recharacterized
amounts shall continue to be treated as Pre-Tax Contributions for all other
purposes of the Plan. If the excess Pre-Tax Contributions are not
recharacterized, such excess Pre-Tax Contributions, plus any income and minus
any loss attributable thereto, shall be distributed to the affected Members as
of the end of such Plan Year. Such income shall include the allocable gain or
loss for the Plan Year.

                  The amount of any excess Pre-Tax Contributions to be
recharacterized or distributed to a Member shall be reduced by Excess Deferrals
previously distributed to him pursuant to Section 4.1 for the taxable year
ending in the same Plan Year. All excess Pre-Tax Contributions shall be returned
to the Members or recharacterized as After-Tax Contributions no later than the
last day of the following Plan Year. The excess Pre-Tax Contributions, if any,
of each Member who is among the Highly Compensated Employees shall be determined
by computing the maximum Actual Deferral Percentage which each such Member may
defer under (a) or (b) of Section 13.3 and then reducing the Actual Deferral
Percentage of some or all of such



                                       61


Members through the distribution of such excess Pre-Tax Contributions of such
Members, on the basis of the amount of Pre-Tax Contributions of such Members, as
necessary to reduce the overall Actual Deferral Percentage for eligible Members
who are among the Highly Compensated Employees to a level which satisfies either
(a) or (b) of Section 13.3, according to the following procedures:

                  (a) The Pre-Tax Contributions of the Highly Compensated
         Employee or Employees with the highest dollar amount of Pre-Tax
         Contributions shall be reduced to equal the dollar amount of the
         Pre-Tax Contributions of the Highly Compensated Employee or Employees
         with the next highest dollar amount of Pre-Tax Contributions;

                  (b) The reduction amount determined in the preceding sentence
         shall be distributed to the Highly Compensated Employee or Employees
         who had the highest dollar amount of Pre-Tax Contributions prior to
         such reduction; and

                  (c) The procedures in clauses (a) and (b) above shall be
         repeated until the total excess Pre-Tax Contributions are distributed
         and compliance is achieved under (a) or (b) of Section 13.3 hereof.

                  If these distributions are made, the Actual Deferral
Percentage is treated as meeting the nondiscrimination test of Section 401(k)(3)
of the Code regardless of whether the Actual Deferral Percentage, if
recalculated after distributions, would satisfy Section 401(k)(3) of the Code.
The above procedures are used for purposes of recharacterizing excess Pre-Tax
Contributions under Section 401(k)(8)(A)(ii) of the Code. For purposes of
Section 401(m)(9) of the Code, if a corrective distribution of excess Pre-Tax
Contributions has been made, or a recharacterization has occurred, the Actual
Deferral Percentage for Highly Compensated Employees is deemed to be the largest
amount permitted under Section 401(k)(3) of the Code.

                  The income or loss attributable to the Member's excess Pre-Tax
Contributions for the Plan Year shall be determined by multiplying the income or
loss attributable to the Member's Pre-Tax Contributions Account for the Plan
Year by a fraction, the numerator of which is the excess Pre-Tax Contributions
and the denominator of which is the Member's Pre-Tax Contributions Account.
Excess Pre-Tax Contributions shall be treated as Annual Additions under Section
5.3 of the Plan.

         13.7 Contribution Percentage: The Contribution Percentage for a
specified group of Employees for a Plan Year shall be the average of the ratios
(calculated separately for each Employee in such group) of:

                  (a) The total of the Employer Matching Contributions and the
         After-Tax Contributions (the "Aggregate Contributions") paid under the
         Plan on behalf of each Employee for such Plan Year which are made on
         account of the Employee's Contributions for the Plan Year, are
         allocated to the Employee's Employer Contribution Account during such
         Plan Year and are paid to the Trust no later than the end of the next
         following Plan Year, to



                                       62


                  (b) The Employee's Compensation for such Plan Year.

                  To the extent permitted by the Code and applicable
regulations, the Employer may elect to take into account, in computing the
Contribution Percentage, pre-tax contributions made under this Plan or any other
plan of the Employer. A Member's Contribution Percentage shall be determined
after determining the Member's Excess Deferrals, if any, pursuant to Section
4.1, and after determining the Member's excess Pre-Tax Contributions pursuant to
Section 13.6.

         13.8 Contribution Percentage Limits: The Contribution Percentage for
the eligible Employees for any Plan Year who are Highly Compensated Employees
shall not exceed the greater of (a) or (b), as follows:

                  (a) The Contribution Percentage for the eligible Employees who
         are not Highly Compensated Employees times 1.25; or

                  (b) The lesser of (i) the Contribution Percentage for the
         eligible Employees who are not Highly Compensated Employees times 2.0
         or (ii) the Contribution Percentage for the eligible Employees who are
         not Highly Compensated Employees plus two percentage points or such
         lesser amount as the Secretary of the Treasury shall prescribe to
         prevent the multiple use of this alternative limitation with respect to
         any Highly Compensated Employee.

                  The Contribution Percentage for any Highly Compensated
Employee for any Plan Year who is eligible to have matching employer
contributions made on his behalf or to make after tax contributions under one or
more plans described in Section 401(a) of the Code that are maintained by an
Employer or an Affiliate in addition to this Plan shall be determined as if all
such contributions were made to this Plan.

                  In the event that this Plan must be combined with one or more
other plans in order to satisfy the requirements of Code Section 401(b), then
the Contribution Percentage shall be determined as if all such plans were a
single plan. If two or more plans are permissively aggregated for the purposes
of Code Section 410(b) (other than the average benefit percentage test) then the
Contribution Percentage shall be determined as if all such plans were a single
plan.

The Plan uses the Contribution Percentage for Members who are Highly Compensated
Employees and non-Highly Compensated Employees for the prior Plan Year in
performing the nondiscrimination testing requirements under this Section for the
current Plan Year.

         13.9 Treatment of Excess Aggregate Contributions: If neither of the
tests described in (a) or (b) of Section 13.8 are satisfied, the excess
Aggregate Contributions, plus any income and minus any loss attributable
thereto, shall be forfeited, or if not forfeitable, shall be distributed no
later than the last day of the Plan Year following the Plan Year in which such
excess Aggregate Contributions were made. Such income shall include the
allocable gain or loss for the Plan Year. The income or loss attributable to the
Member's excess Aggregate Contributions for the Plan Year shall be determined by
multiplying the income or loss attributable to the Member's



                                       63


Employer Contribution Account and After-Tax Contribution Account for the Plan
year by a fraction, the numerator of which is the excess Aggregate Contribution,
and the denominator of which is the Member's total Employer Contribution Account
and After-Tax Contribution Account balance. Excess Aggregate Contributions shall
be treated as Annual Additions under Section 5.3 of the Plan.

                  The excess Aggregate Contributions, if any, of each Member who
is among the Highly Compensated Employees shall be determined by computing the
maximum Contribution Percentage under (a) or (b) of Section 13.8 and then
reducing the Contribution Percentage of some or all of such Members whose
contribution Percentage exceeds the maximum through the distribution or
forfeiture of the excess Aggregate Contributions, on the basis of the amount of
such excess contributions attributable to such Members, as necessary to reduce
the overall Contribution Percentage for eligible Members who are among the
Highly Compensated Employees to a level which satisfies either (a) or (b) of
Section 13.8 as necessary according to the following procedures:

                  (a) The Aggregate Contributions of the Highly Compensated
         Employee or Employees with the highest dollar amount of such
         contributions shall be reduced to equal the dollar amount of the
         Aggregate Contributions of the Highly Compensated Employee or Employees
         with the next highest dollar amount of such contributions;

                  (b) The reduction amount determined in the preceding sentence
         shall be forfeited by or, if not forfeitable, distributed to the Highly
         Compensated Employee or Employees who had the highest dollar amount of
         Aggregate Contributions prior to such reduction; and

                  (c) The procedures in clauses (a) and (b) above shall be
         repeated until the total excess Aggregate Contributions are forfeited
         and/or distributed and compliance is achieved under (a) or (b) of
         Section 13.9 hereof.

                  If these forfeitures and/or distributions are made, the
Contribution Percentage is treated as meeting the nondiscrimination test of
Section 401(m)(2) of the Code regardless of whether the Contribution Percentage,
if recalculated after such forfeitures and/or distributions would satisfy
Section 401(m)(2) of the Code. For purposes of Section 401(m)(9) of the Code, if
a corrective distribution of excess Aggregate Contributions has been made, the
Contribution Percentage for Highly Compensated Employees is deemed to be the
largest amount under Section 401(m)(2) of the Code.

                  For each Member who is a Highly Compensated Employee, the
amount of excess Aggregate Contributions is equal to the total Employer Matching
Contributions and the After-Tax Contributions on behalf of the Member
(determined prior to the application of this paragraph) minus the amount
determined by multiplying the Member's actual contribution ratio (determined
after application of this paragraph) by his Compensation used in determining
such ratio. The individual ratios and Contribution Percentages shall be
calculated to the nearest 1/100 of 1% of the Employee's Compensation.



                                       64


Notwithstanding anything in this Plan to the contrary, any Employer Matching
Contributions attributable to a Member's Pre-Tax or After-Tax Contributions
which are distributed to a Member pursuant to the requirements of the Article
XIII, will be forfeited.

         13.10 Multiple Use of Alternative Limitation: The rules set forth in
Code Section 1.401(m)-2(b) for determination of multiple use of the alternative
methods of compliance with respect to Sections 13.3(b) and 13.8(b) are hereby
incorporated into the Plan. If a multiple use of the alternative limitation
occurs with respect to two or more plans or arrangements maintained by an
Employer it shall be treated as an excess Aggregate Contribution and must be
corrected by reducing the actual contribution ratio of Highly Compensated
Employees eligible both to make elective contributions to receive matching
contributions under the 401(k) arrangement or to make contributions under the
401(m) plan. Such reduction shall be by the leveling process set forth in
Section 13.9.



                                       65
