by design or operation discriminate significantly in favor of "highly
compensated employees" (as defined in Code Section 414(q)), and (iii) is applied
to all similarly situated Employees eligible to participate in the Plan under
Article II. Furthermore, in the event that the Plan constitutes a plan of a

         event an Employee or Member terminates his Service (at a time other
         than an authorized leave of absence) and subsequently resumes his
         Service, if his Reemployment Date is within 12 months of his Severance
         from Service Date, such Period of Severance shall be treated as a
         period of Service for purposes of Vesting Service.

                  (b)      In the event an Employee or Member terminates his
         Service during an authorized leave of absence and subsequently resumes
         his Service, if his Reemployment Date is within 12 months of the
         beginning of such leave of absence, such Period of Severance shall be

         include all of his periods of employment with an Employer or Affiliate
         prior to January 1, 2002 which would constitute Service determined
         under the terms of the Plan if applied to such periods of employment.

                  (c)      In the case of an individual who terminates
         employment at a time when he has a 0% vested interest in his Accrued
         Benefits and who then incurs a Period of Severance that equals or
         exceeds five years, such individual's period of Service completed
         before such Period of Severance shall be forfeited and completely
         disregarded in determining his years of Vesting Service.

                             NON-COVERED EMPLOYMENT

                  Certain Intra-Company Transfers: In the event that a Member is
transferred from an employment classification with an Employer that is covered
by this Plan (a) to an employment classification with the same Employer or with

Affiliate that is not an Employer, such Member shall retain all the benefits
accrued to him under this Plan prior to the date of transfer and shall retain
such benefits until his subsequent retirement or other termination of employment
with an Employer or any Affiliate. Such Member shall also continue to accrue
Vesting Service for all periods of employment with an Employer or an Affiliate
while he is not covered by this Plan.

                  In the event that an employee is transferred (i) from an
employment classification with an Employer that is not covered by this Plan to
an employment classification with the same Employer or another Employer that is
covered by this Plan or (ii) from employment with an Affiliate to an employment
classification with an Employer that is covered by this Plan, such employee
shall retain his credited service and all benefits accrued to him under a
retirement plan, if any, covering his employment prior to the date of the
transfer; provided, however, that for purposes of this Plan such employment
prior to the date of transfer shall be considered only for the purposes of
determining (a) his eligibility to participate (if applicable) in this Plan and
(b) his vested interest under this Plan. After the date of such transfer, such
employee shall accrue the benefits specified under this Plan provided he is
otherwise eligible therefor. It is intended by this Article VI to credit an
Employee or Member with Service for eligibility purposes, if applicable, and
with Vesting Service for vesting purposes during all periods of employment while
in a Transferred Member status and all such Service and such Vesting Service
shall be determined as though such employment while in a Transferred Member
status were employment by an Employer covered by this Plan.

         in his Cash Balance Account during his absence and (ii) Interest
         Credits in his existing Cash Balance Account from and after his
         Reemployment Date (but no future Contribution Credits unless and until
         he is again an Eligible Employee).

                  (b)      If a Member terminates employment with all Employers
         and Affiliates, takes his Accrued Benefit in a single, lump-sum
         distribution, and is subsequently reemployed as an Eligible Employee,
         except as provided in subsection (c) below, such Member shall not have
         his Cash Balance Account restored upon his Reemployment Date. A new
         Cash Balance Account shall be established for the Member with a zero
         balance as of his Reemployment Date and Contribution Credits and
         Interest Credits shall be made prospectively to such account in
         accordance with this Article VII.

                  (c)      If a Member terminates employment with all Employers
         and Affiliates, receives a deemed distribution pursuant to Section
         11.5(b), and is subsequently reemployed by an Employer or an Affiliate,
         if such Member's Period of Severance prior to his Reemployment Date is
         less than five years, then such Member's Cash Balance Account shall
         restored upon his Reemployment Date in the amount deemed distributed.
         If such Member is reemployed as an

         Eligible Employee, he shall be eligible to receive prospective
         Contribution Credits and Interest Credits in his restored Cash Balance
         Account from and after his Reemployment Date, in accordance with this
         Article VII. If such Member is not an Eligible Employee upon his
         Reemployment Date, then he shall be eligible to receive prospective
         Interest Credits in his restored Cash Balance Account from and after
         his Reemployment Date (but no future Contribution Credits unless and
         until he is again an Eligible Employee).

                  (d)      If a Member terminates employment with all Employers
         and Affiliates, commences taking his Accrued Benefit in an annuity form
         of payments, and is subsequently reemployed as an Eligible Employee,
         such Member's annuity payments shall not be suspended and his prior
         Cash Balance Account shall be disregarded as of his Reemployment Date.
         A new Cash Balance Account shall be established for the Member with a
         zero balance as of his Reemployment Date and Contribution Credits and
         Interest Credits shall be made prospectively to such account in
         accordance with this Article VII.

                                  ARTICLE VIII

                      REQUIREMENTS FOR RETIREMENT BENEFITS

         8.1      Retirement Benefit: A Member who terminates his employment
after satisfying the vesting requirements in Section 5.1 shall be eligible to
receive his Accrued Benefit (as described in Article VII) on or after his Early
Retirement Date or Normal Retirement Date commencing on his Annuity Starting
Date payable in accordance with the provisions of Article XI.

         8.2      Retirement Benefits Following an Authorized Leave of Absence:
A Member who has been on an authorized leave of absence shall be eligible to
receive his Accrued Benefit, after satisfying the vesting requirements in
Section 5.1 on or after his Early Retirement Date or Normal Retirement Date,
following the Member's Severance from Service Date, as determined pursuant to
Article III.

                                   ARTICLE IX

                                 DEATH BENEFITS

         9.1      Death Benefit of a Member Who Dies During Service: The
Beneficiary of each Member who dies during Service shall be entitled to a Death
Benefit equal to the Actuarial Equivalent of the Member's Cash Balance Account
payable as follows:

                  (a)      If the Member's Beneficiary is his Spouse, the Death
         Benefit shall be payable to such Spouse in the form of an immediate
         Single Life Annuity, in accordance with Section 9.3, that is the
         Actuarial Equivalent of the balance of the Member's Cash Balance
         Account as of the end of the month immediately preceding the
         commencement of such benefits, and commencing upon the Spouse's
         election to commence receipt of benefits under this Section. The Spouse
         may instead elect to receive the entire benefit in a single, lump-sum
         payment equal to the balance of the Member's Cash Balance Account as of
         the end of the month immediately preceding the commencement of such
         benefit. A Spouse's election to receive the entire benefit in a
         lump-sum payment must be made prior to the commencement of payment in
         annuity form and must be made in accordance with the requirements for
         election of an optional form of benefit applicable to an unmarried
         Member as set forth in Section 11.3.

                           If the Member's Beneficiary is his Spouse and payment
         of the Death Benefit is deferred, the Member's Cash Balance Account
         shall continue to be credited with Interest Credits until the last day
         of the Quarter immediately preceding the date as of which payment of
         the Death Benefit is made or commences, plus a prorated Interest Credit
         based on the number of whole months in the period from the beginning of
         the Quarter in which the payment of the Death Benefit

<PAGE>

                                                                   EXHIBIT 10.51

         is made or commences through the last day of the month immediately
         preceding the date on which payment is made or commences.

                  (b)      If the Member's Beneficiary is not his Spouse, then
         the Death Benefit shall be payable in a single, lump sum equal to the
         balance of the Member's Cash Balance Account as of the end of the month
         immediately preceding the commencement of such benefit as soon as
         reasonably practicable, but in no event later than five years, after
         the Member's date of death.

                  (c)      Notwithstanding any provision herein to the contrary,
         if the Actuarial Equivalent present value of a Death Benefit payable on
         behalf of a Member does not exceed $5,000, then such Death Benefit
         shall be paid to the Spouse or other Beneficiary, as applicable, in a
         single, lump sum distribution equal to the balance of the Member's Cash
         Balance Account as of the end of the month immediately preceding the
         commencement of such benefit as soon as administratively practicable
         after the Member's date of death.

         9.2      Death Benefit of a Member Who Dies After His Severance of
Service Date: The Beneficiary of a Member who (a) after he terminated Service,
and (b) had not yet commenced payment of his Accrued Benefit shall be entitled
to a Death Benefit equal to the balance in the Member's Cash Balance Account as
of the end of the month immediately preceding the Member's death. Subject to
Section 9.3, a Death Benefit under this Section shall normally be payable to a
Beneficiary in a single, lump sum distribution as soon as practicable after the
Member's death; provided, however, that if the Beneficiary is the Member's
Spouse, then the foregoing Death Benefit shall be paid in the form of a
Pre-Retirement Survivor Annuity payable as of the date of the Member's death,
unless the Spouse elects, as provided in Section 11.2, to received such benefit
as a single, lump sum distribution. Such benefit shall commence as soon as
practicable after the death of the Member.

         9.3      Pre-Retirement Survivor Annuity: Notwithstanding anything
herein to the contrary, the benefit payable to a Beneficiary who is a Spouse
under this Article IX must be paid in the form of a Single Life Annuity over the
Spouse's lifetime that is a Pre-Retirement Survivor Annuity, unless the Spouse
elected otherwise in accordance with Sections 9.1 to receive the benefit in the
form of a single, lump sum distribution. The Member must inform the Plan as to
any change in his marital status and until so informed the Plan shall be
entitled to rely on the Member's assertion of marital status as originally
established.

         9.4      Effect on Optional Form Election: Any Member who dies prior to
his Annuity Starting Date shall be entitled only to a Death Benefit pursuant to
this Article IX, regardless of whether such Member elected an optional form of
benefit pursuant to the provisions of Section 11.2.

         9.5      No Death Benefits After Commencement of Benefits: No Death
Benefit shall be payable under this Article IX with respect to a Member who has
commenced payment of his Accrued Benefit.

                                    ARTICLE X
                                  BENEFICIARIES

         10.1     Designation of Beneficiary: Unless otherwise provided below,
each Member may designate a contingent annuitant or joint pensioner
("Beneficiary") to receive the remaining guaranteed payments or survivor pension
under an optional Pension elected pursuant to Section 11.4 or to receive any
Death Benefit payable under Article IX. Such designation must be in writing and
filed with the Committee, in the form and manner prescribed by the Committee.
The Member may change or cancel any such optional pension election at the times
and subject to uniform rules established by the Committee.

                  The Beneficiary shall be the Beneficiary or Beneficiaries
designated by the Member in a written designation filed with the Committee, or
if not so designated, the Beneficiary designated under this Section shall be the
Member's Spouse, if any. If no such designation shall have been so filed, or if
no designated Beneficiary survives the Member or if a designated Beneficiary
cannot be located by the Committee, using reasonable diligence, within six
months of the death of the Member, then such remaining Pension or Death Benefit,
as applicable, shall be payable to the duly appointed and serving personal
representative of the Member's estate, but only if that personal

<PAGE>

                                                                   EXHIBIT 10.51

representative can provide the Committee with what the Committee reasonably
determines is satisfactory documentary proof of that appointment and of the
personal representative's identity (collectively, "Documentary Proof"); if,
within six months of the Member's death, there is no duly appointed and serving
personal representative of the Member's estate who has provided the Committee
with Documentary Proof, then such remaining Pension or Death Benefit, as
applicable, shall be payable to the Member's heirs at law, determined in
accordance with the laws of intestate succession of the state in which the
Member was domiciled at the time of the Member's death, provided that such heirs
provide the Committee with what the Committee reasonably determines is
satisfactory Documentary Proof of information the Committee believes it needs to
make distributions to such heirs, including, but not limited to, the numbers,
names, addresses, social security numbers, and birth dates of such heirs. No
designation of any Beneficiary shall be effective unless in writing and received
by the Member's Employer and in no event shall it be effective as of the date
prior to such receipt. If married, a Member's Spouse will automatically be
designated as his Beneficiary. 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.

                  Each Member shall have the right at any time to designate and
to rescind or change any designation of a contingent Beneficiary or
Beneficiaries to receive benefits in the event of his death and the death
(predeceasing the death of the Member) of the primary Beneficiary. Any such
designation, change or rescission of designation, shall be made in such form and
manner as prescribed by the Committee, including, but not limited to, in writing
or by electronic means. A contingent Beneficiary or Beneficiaries shall be
entitled to receive any unpaid Death Benefit (whether payable in a lump sum or
in installments for a guaranteed period) only if no primary Beneficiary is alive
or legally entitled to receive it on the date of payment of the benefit or any
installment thereof. The estate, assignee or appointee of either a primary or a
contingent Beneficiary shall have no interest in or right to receive any Death
Benefit payment not actually made before such Beneficiary's death.

                  The provisions of this Article X shall have no application to
the designation of or change in designation of a joint pensioner by a Member
electing a joint and survivor option, which shall be governed solely by the
provisions of Article XI hereof. If the Committee shall be in doubt as to the
right of any Beneficiary designated by a deceased Member to receive any unpaid
death benefit, 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 to the amount so paid.

         10.2     Spouse as Beneficiary: Notwithstanding anything herein to the
contrary, if a Member who is eligible for a Death Benefit under Article IX has a
Spouse at the time of his death, then such Member's Beneficiary shall be his
Spouse and no designation, with or without Spousal consent, of any other
Beneficiary shall be valid.

                                   ARTICLE XI
                               PAYMENT OF PENSION

         11.1     Payment of Accrued Benefit: Anything to the contrary
notwithstanding, a Member's Accrued Benefit under this Plan shall be payable
pursuant to the following requirements:

                  (a)      Commencement of Accrued Benefit: A Member who
         terminates his employment with all Employers and Affiliates and who has
         a vested right to an Accrued Benefit under the Plan may elect to
         commence payment of his Accrued Benefit as of his Early Retirement Date
         or his Normal Retirement Date. The distribution of his Accrued Benefit
         shall begin no later than the 60th day after the latest of the close of
         the year in which (i) the Member attains age 65 or (ii) the Member
         terminates Service. Notwithstanding any provision in the Plan to the
         contrary, if a Member's Accrued Benefit has not commenced by the end of
         the Plan Year during which occurs his Normal Retirement Date, such
         Member's Accrued Benefit shall not be actuarially increased to reflect
         the delay in commencement in his Accrued Benefit after his Normal
         Retirement Date, in accordance with Section 203(a)(3) of ERISA and Code
         Section 411(b)(1)(H), and the applicable regulations.

<PAGE>

                                                                   EXHIBIT 10.51

                  (b)      Deferred Commencement of Accrued Benefit: Each
         Member's Accrued Benefit shall be distributed to him not later than the
         Member's Required Beginning Date. The distribution of a Member's
         Accrued Benefit pursuant to this subsection (b) shall be made in
         accordance with the requirements of Code Section 401(a)(9), including
         the incidental death benefit requirements of Code Section 401(a)(9)(G),
         and the Treasury Regulations thereunder (including Proposed Regulation
         Section 1.401(a)(9)-2), with such Member's Accrued Benefit reduced by
         the Actuarial Equivalent value of the payments received by him.

         11.2     Normal Form of Payment: The normal forms of payment of a
Member's Accrued Benefit are as follows:

                  (a)      Single Life Annuity: For an unmarried Member, his
         vested Accrued Benefit shall be payable monthly on the first day of
         each calendar month in the form of a Single Life Annuity that is the
         Actuarial Equivalent of his Accrued Benefit commencing with the
         Member's Annuity Starting Date and closing with the payment due on the
         first day of the month of the Member's death, unless he is eligible for
         and duly elects an optional form of payment, as provided in Section
         11.4 below.

                  (b)      Qualified Joint and Survivor Annuity. For a Member
         who has a Spouse as of his Annuity Starting Date, his vested Accrued
         Benefit shall be payable in the form of a Qualified Joint and Survivor
         Annuity that is the Actuarial Equivalent of his Single Life Annuity
         otherwise payable to such Member as of his Annuity Starting Date. The
         Qualified Joint and Survivor Annuity shall be payable unless the Member
         shall have theretofore elected in writing, with the written consent of
         his Spouse, not to receive such Qualified Joint and Survivor Annuity
         after having received a written explanation of the terms and conditions
         of the Qualified Joint and Survivor Annuity and the effect of an
         election not to receive such Qualified Joint and Survivor Annuity, but
         to receive his Accrued Benefit in the form of Single Life Annuity or
         other optional form of payment as provided in Section 11.4 hereunder.

                  (c)      No amount attributable to the Qualified Joint and
         Survivor Annuity shall be payable, however, if a Member entitled to his
         Accrued Benefit shall die after he has made his election to commence
         his benefit under the Plan but before his Annuity Starting Date.

         11.3     Election to Waive Qualified Joint and Survivor Annuity. A
written explanation of the terms and conditions of the Qualified Joint and
Survivor Annuity and the effect of refusing it will be furnished to a Member no
less than 30 days and no more than 90 days prior to the date when he would first
become eligible to commence receiving an Accrued Benefit hereunder. The Member
may request additional information regarding the Qualified Joint and Survivor
Annuity within 60 days of the furnishing of such explanation to him. A written
reply will be made within 30 days of his request. During an election period
beginning 90 days prior to the Annuity Starting Date, the Member may, with the
written consent of his Spouse, elect in writing to the Committee not to receive
the Qualified Joint and Survivor Annuity, in which case the normal form of
payment described in Section 11.2(a) shall be applicable unless the Member
elects payment in one of the optional forms under Section 11.4. Throughout the
election period, the Member may file written revocations or written elections
with the Committee. The written explanation described above may be provided
after an Annuity Starting Date. The 90-day applicable election period to waive
the Qualified Joint and Survivor Annuity shall not end before the 30th day after
the date on which such explanation is provided. A Member may elect (with any
applicable Spousal consent) to waive any requirement that the written
explanation be provided at least 30 days before his Annuity Starting Date (or
waive the 30-day requirement as provided above) if the distribution commences
more than seven (7) days after such explanation is provided.

                  (a)      A married Member who elects not to receive the
         Qualified Joint and Survivor Annuity must obtain the consent of his
         Spouse to elect payment in one of the optional forms of payment
         provided in Section 11.4. A Spouse's consent shall not be effective
         unless: (i) the Member's Spouse consents in writing to the election;
         (ii) the election designates a specific alternate Beneficiary
         (including any class of Beneficiaries or any contingent Beneficiaries)
         and a form of benefit which may not be changed without spousal consent
         (or the Spouse expressly

<PAGE>

                                                                   EXHIBIT 10.51

         permits designations by the Member without any further spousal
         consent); (iii) the Spouse's consent acknowledges the effect of the
         election; and (iv) the Spouse's consent is witnessed by a Plan
         representative or notary public. If it is established to the
         satisfaction of a Plan representative that such written consent may not
         be obtained because there is no Spouse or the Spouse cannot be located,
         a waiver will be deemed a qualified election. Any consent by a Spouse
         under this Section (or establishment that the consent of the Spouse
         cannot be obtained) shall be effective only with respect to such
         Spouse. A consent that permits designations by the Member without any
         requirement of further consent by the Spouse must acknowledge that the
         Spouse has the right to limit consent to a specific beneficiary, and a
         specific form of benefit where applicable, and that the Spouse
         voluntarily elects to relinquish either or both of such rights. A
         revocation of a prior waiver may be made by a Member without the
         consent of the Spouse at any time prior to the commencement of
         benefits. The number of revocations shall not be limited. For purposes
         of this Section, the Spouse or surviving Spouse of the Member shall be
         deemed the recipient under the Qualified Joint and Survivor Option,
         provided that a former Spouse will be treated as the Spouse or
         surviving Spouse to the extent provided under a qualified domestic
         relations order as described in Section 414(p) of the Code.

         11.4     Optional Form of Payment(a) In lieu of his normal form of
         payment pursuant to Section 11.2, a Member who has terminated his
         Service may, in accordance with the requirements of Section 11.3, elect
         to have his vested Accrued Benefit paid in one of the following
         optional forms of payment, each of which shall be the Actuarial
         Equivalent of the normal form of payment otherwise payable to such
         Member:

                           (i)      Option 1: A single, lump-sum payment equal
                  to the Actuarial Equivalent of the Member's Accrued Benefit
                  payable at the time of the Member's Annuity Starting Date.

                           (ii)     Option 2: A Single Life Annuity as described
                  in Section 11.2(a) (in the case of a married Member only with
                  the consent of his Spouse).

                  (b)      Upon the commencement of benefits to a Member who has
         made a valid election of an optional benefit hereunder, the form of
         optional benefit and any Beneficiary designation shall become
         irrevocable except to the extent otherwise required pursuant to Section
         11.2(b).

                  (c)      Any optional forms of benefit, which are "Section
         411(d)(6) protected benefits," as described in Treasury Regulation
         Section 1.411(d)-4, shall continue to be optional forms of benefits
         for Members to whom the optional forms apply notwithstanding any
         subsequent amendment of the Plan purporting to revise or delete such
         optional form of benefit and notwithstanding any contrary provision of
         subsection (a) of this Section 11.4.

         11.5     Payment of Small Benefits(a) Notwithstanding any provision
         herein, if at the time of the Member's Severance from Service Date the
         Actuarial Equivalent present value of a Member's Accrued Benefit does
         not exceed $5,000, then such benefit shall be paid to the Member in a
         single, lump sum distribution as soon as administratively practicable
         after the Member's termination of Service. If the Actuarial Equivalent
         present value of an Alternate Payee's amounts assigned pursuant to a
         qualified domestic relations order, as defined in Code Section 414(q)
         ("QDRO"), does not exceed $5,000, then such benefit shall be paid as
         soon as administratively practicable without the Member's or the
         Alternate Payee's consent. Any Member or Alternate Payee entitled to a
         distribution in accordance with this subsection shall be entitled to
         elect to have such benefit paid as a direct transfer in accordance with
         Code Section 401(a)(31) and pursuant to the procedures then established
         by the Committee.

                  (b)      For purposes of this Section 11.5, if at the time of
         the Member's Severance from Service Date, his vested interest in his
         Accrued Benefit is 0%, then such Member shall be deemed to have
         received a total distribution of all of his vested Accrued Benefit.

         11.6     Direct Rollovers: Notwithstanding any provision of the Plan to
the contrary that would otherwise limit a Distributee's election under this
Section, a Distributee may elect, at the time and in the manner prescribed by
the Committee, to have any portion of an Eligible Rollover Distribution paid
directly to an Eligible Retirement Plan specified by the Distributee in a Direct
Rollover. For the purposes of this Section the following definitions shall
apply:

                  (a)      "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 10 years or more;
         any distribution to the extent such distribution is required under
         Section 401(a)(9) of the Code; any hardship withdrawal described in
         Section 401(k)(2)(B)(i)(IV) of the Code; and the portion of any
         distribution that is not includable in gross income (determined without
         regard to the exclusion for net unrealized appreciation with respect to
         employer securities).

                  (b)      "Eligible Retirement Plan" shall mean an individual
         retirement account described in Section 408(a) of the Code, an
         individual retirement annuity described in Section 408(b) of the Code,
         an annuity plan described in Section 403(a) of the Code, an eligible
         deferred compensation plan described in Section 457(b) of the Code
         which is maintained by an eligible employer described in Section
         457(e)(1)(A) of the Code, an annuity contract described in Section
         403(b) of the Code, or a qualified trust described in Section 401(a) of
         the Code, that accepts the Distributee's Eligible Rollover
         Distribution.

                  (c)      "Distributee" shall mean a Member or former Member of
         the Plan. In addition, the Member's or former 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.

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

                                   ARTICLE XII
                                CLAIM PROCEDURES

         12.1     Presenting Claims for Benefits: Any Member or any other person
claiming under a deceased Member, such as the Spouse or Beneficiary, or an
authorized representative (designated in the manner required by the Committee)
of such Member, Spouse or Beneficiary (collectively, the "Claimant"), may submit
written claim to the Committee for the payment of any benefit asserted to be due
him under the Plan, which shall set forth the nature of the claim and such other
information as the Committee may reasonably request. Upon the receipt of any
claim for benefits required by this Section, the Committee shall determine
whether or not the Claimant is entitled to a benefit hereunder and, if so, the
amount thereof, and shall notify the Claimant of its findings, in accordance
with the Department of Labor regulations 29 C.F.R. Section 2560.503-1.

                  The Committee shall notify the Claimant of its benefits
determination within a reasonable time, not to exceed 90 days, after receipt of
the claim, unless the Committee determines that special circumstances require an
extension of time, not to exceed 90 days from the end of the initial 90-day
period, for processing the claim. If such an extension of time is required,
written notice of the extension shall be furnished to the Claimant prior to the
end of the initial 90-day period indicating the special circumstances requiring
an extension of time and the date by

<PAGE>

                                                                   EXHIBIT 10.51

which the Committee expects to render its final decision. The initial 90-day
period shall commence at the time the claim is filed with the Committee,
regardless of whether or not all information necessary for the Committee to make
its determination accompanies the filing. If an extension of the 90-day period
is required due to the Claimant's failure to submit such necessary information,
such period shall be tolled from the date on which the extension notice is sent
to the Claimant until the date the Claimant provides such additional
information.

                  The Committee shall provide the Claimant with written or
electronic notice of its decision to deny a claim, in whole or in part, and such
notice shall set forth, in a manner calculated to be understood by the Claimant:

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

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

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

                  (d)      a description of the claims review procedure set
         forth in Section 12.2 hereof and the applicable time limits, including
         the Claimant's right to bring a civil action under Section 502(a) of
         ERISA following a denial on review.

If written or electronic notice of a 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 procedures described in
Section 12.2.

         12.2     Claims Review Procedure: If the Committee denies the benefits
claim filed by a Claimant under Section 12.1, either in whole or in part, such
Claimant 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 claim
or, if no such notice has been given, within 60 days after the claim is deemed
denied under Section 12.1, to request a review of his claim and entitlement to
the benefit applied for and the denial of such benefits. The Claimant may submit
written comments, documents, records and other information relating to his claim
for benefits. Upon request, and free of charge, the Claimant shall be provided
reasonable access to, and copies of, all documents, records and other
information relevant to his claim for benefits. The Committee shall reconsider
the claim in light of all such comments, documents and other information
submitted by the Claimant, without regard to whether such information had been
submitted or considered in the initial review process under Section 12.1. If
deemed necessary by the Committee, in its sole discretion, the Committee may
hold a formal hearing on the benefits claim.

                  The Committee shall conduct a full and fair review of the
claim and provide the Claimant with written or electronic notice of its final
determination within a reasonable time, not to exceed 60 days, after receipt of
the Claimant's application for review, unless the Committee determines that
special circumstances require an extension of time, not to exceed 60 days from
the end of the initial 60-day period, to review the claim (such as the need to
hold a formal hearing). If such an extension of time is required, written notice
of the extension shall be furnished to the Claimant prior to the end of the
initial 60-day period indicating the special circumstances requiring such an
extension and the date by which the Committee expects to render its decision.
The initial 60-day period shall commence at the time the application for review
is filed with the Committee, regardless of whether or not all information
necessary for the Committee to make its determination accompanies the filing. If
an extension of the 60-day period is required due to the Claimant's failure to
submit such necessary information, such period shall be tolled from the date on
which the extension notice is sent to the Claimant until the date the Claimant
provides such additional information.

                  If the Committee denies the claim on review, either in whole
or in part, the notice of final determination shall set forth, in a manner
calculated to be understood by the Claimant, the specific reasons for the denial
and specific references to the pertinent provisions of the Plan upon which the
denial is based, the Claimant's right to receive upon request, free of charge,
reasonable access to, and copies of, all relevant documents, records and other
information to his claim and the Claimant's right to bring a civil action under
Section 502(a) of ERISA. If the

                                                                   EXHIBIT 10.51

decision on review is not furnished within the time period set forth above, the
claim shall be deemed denied on review. Benefits under this Plan will only be
paid if the Committee decides in its discretion that the Claimant is entitled to
them.

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

                                  ARTICLE XIII
                               PLAN ADMINISTRATION

         13.1     Appointment of Committee: The Directors shall appoint an
Administrative Committee (the "Committee") of not less than three persons, each
of whom may or may not be a Member of the Plan and each of whom shall serve at
the pleasure of the Directors. Any person so appointed shall signify his
acceptance by filing written acceptance with the Directors and with the
Secretary of the Committee. Each member of the Committee shall serve for such
term as the Directors may designate or until his death, resignation or removal
by the Directors. The Directors shall promptly appoint successors to fill any
vacancies in the Committee.

         13.2     Records of the Committee: The Committee shall keep appropriate
records of its proceedings and the administration of the Plan. The Committee
shall make available to Members and their Beneficiaries for examination, during
business hours, such records of the Plan as pertain to the examining person and
such documents relating to the Plan as are required by ERISA.

         13.3     Committee Action: The Committee may act through the
concurrence of a majority of its members expressed either at a meeting of the
Committee, or in writing without a meeting. Any member of the Committee, or the
Secretary or Assistant Secretary of the Committee (who need not be members of
the Committee), may execute on behalf of the Committee any certificate or other
written instrument evidencing or carrying out any action approved by the
Committee. The Committee may delegate any of its rights, powers and duties to
any one or more of its members or to an agent. The Chairman of the Committee
shall be agent of the Plan and the Committee for the service of legal process at
the principal office of the Company in Houston, Texas.

         13.4     Committee Disqualification: A member of the Committee who may
be a Member of the Plan shall not vote on any question relating specifically to
himself.

         13.5     Committee Compensation, Expenses and Adviser: The members of
the Committee shall serve without bond, unless otherwise required by law, and
without compensation for their services as such. The Committee may select, and
authorize the Trustee to compensate suitably, such attorneys, agents, actuaries
and representatives as it may deem necessary or advisable to the performance of
its duties. All expenses of the Committee that shall arise in connection with
the administration of the Plan shall be paid by the Company or by the Trustee
out of the Trust Fund.

         13.6     Committee Liability: Except to the extent that such liability
is created by ERISA, no member of the Committee shall be liable for any act or
omission of any other member of the Committee, nor for any act or omission on
his own part except for his own gross negligence or willful misconduct, nor for
the exercise of any power or discretion in the performance of any duty assumed
by him hereunder. The Company shall indemnify and hold harmless each member of
the Committee from any and all claims, losses, damages, expenses (including
counsel fees approved by the Committee), and liabilities (including any amounts
paid in settlement with the Committee's approval but excluding any excise tax
assessed against any member or members of the Committee pursuant to the
provisions of Code Section 4975) arising from any act or omission of such member
in connection with duties and responsibilities under the Plan, except when the
same is judicially determined to be due to the gross negligence or willful
misconduct of such member.

         13.7     Committee Determinations: The Committee, on behalf of the
Members and their Beneficiaries, shall enforce this Plan in accordance with its
terms and shall have all powers necessary for the accomplishment of that
purpose, including, but not by way of limitation, the following powers:

                  (a)      To employ such agents and assistants, such counsel

                  (b)      To authorize one or more of their number, or any
         agent, to make any payment, or to execute or deliver any instrument, on
         behalf of the Committee, except that all requisitions for funds from,
         and requests, directions, notifications, certifications, and
         instructions to, the Trustee or to the Company shall be signed either
         by a member of the Committee or by the Secretary or Assistant Secretary
         of the Committee;

                  (c)      To determine from the records of the Company the
         considered Compensation, Service and other pertinent facts regarding
         Employees and Members for the purposes of the Plan;

                  (d)      To construe and interpret the Plan, decide all
         questions of eligibility and determine the amount, manner and time of
         payment of any benefits hereunder;

                  (e)      To prescribe forms and procedures to be followed by
         Employees for participation in the Plan, by Members or Beneficiaries
         filing applications for benefits, and for other occurrences in the
         administration of the Plan;

                  (f)      To prepare and distribute, in such manner as the
         Committee determines to be appropriate, information explaining the
         Plan;

                  (g)      To furnish the Company, Employers and the Members,

         the Trust Fund by a written authorization signed either by a member of
         the Committee or by the Secretary or Assistant Secretary of the
         Committee; provided, however, that disbursements for ordinary expenses
         incurred in the administration of the Trust Fund and disbursements to
         Members need not be authorized by the Committee;

                  (j)      To interpret and construe all terms, provisions,
         conditions and limitations of this Plan and to reconcile any
         inconsistency or supply any omitted detail that may appear in this Plan
         in such manner and to such extent, consistent with the general terms of
         this Plan, as the Committee shall deem necessary and proper to
         effectuate the Plan for the greatest benefit of all parties interested
         in the Plan;

                  (k)      To make and enforce such rules and regulations for
         the administration of the Plan as are not inconsistent with the terms
         set forth herein; and

                  (l)      To furnish the Actuary with all such information as
         the Actuary may require from time to time for the purpose of making
         actuarial computations as to the Plan.

other pertinent facts as the Committee may require; and the

<PAGE>

                                                                   EXHIBIT 10.51

Committee shall advise the Trustee of such of the foregoing facts as may be
pertinent to the Trustee's administration of the Trust Fund.

         13.9     General Powers of the Committee: In addition to all other
powers herein granted, and in general consistent with the provisions hereof, the
Committee shall have all other rights and powers reasonably necessary to
supervise and control the administration of this Plan. The determination of any
fact by the Committee and the construction placed by the Committee upon the
provisions of this Plan shall be binding upon all of the Members under the Plan,
their Beneficiaries and the Employers.

         13.10    Uniform Administration: Whenever in the administration of the
Plan, any action is required by an Employer or the Committee, including, but not
by way of limitation, action with respect to eligibility of Employees,
contributions and benefits, such action shall be uniform in nature as applied to
all persons similarly situated, and no action shall be taken which will
discriminate in favor of Members who are officers or shareholders of an
Employer, highly compensated Employees, or persons whose principal duties
consist of supervising the work of others.

         13.11    Reporting Responsibilities: As Administrator of the Plan under
ERISA, the Committee shall file or cause to be filed with the appropriate office
of the Internal Revenue Service, the Department of Labor or the Pension Benefit
Guaranty Corporation all reports, returns, notices and other information
required under ERISA, including, but not limited to, the summary plan
description, annual reports and amendments thereof.

         13.12    Disclosure Responsibilities: The Committee shall make
available to each Member and Beneficiary such records, documents and other data
as may be required under ERISA, and Members or Beneficiaries shall have the
right to examine such records at reasonable times during business hours. Nothing
contained in this Plan shall give any Member or Beneficiary the right to examine
any data or records reflecting the compensation paid to any other Member or
Beneficiary, except as may be required under ERISA.

         13.13    Allocation of Responsibilities Among Fiduciaries: The
Employers, the Committee, as designated pursuant to the terms of the Plan, the
Trustee and any other person designated as a Fiduciary with respect to the Plan
or the Trust Agreement (hereinafter collectively the "Fiduciaries") shall have
only those specific powers, duties, responsibilities and obligations as are
specifically given them under this Plan and/or the Trust Agreement. In general,
the Employers shall have the sole responsibility for making the contributions
provided for under Section 14.2. The Company shall have the sole authority to
appoint and remove the Trustee and the members of the Committee, respectively,
and to amend or terminate, in whole or in part, this Plan. Each other Employer
may amend or terminate this Plan with respect to its Employees to the extent
provided in Articles XVII and XVIII. The Committee shall have the sole
responsibility to administer the Plan and to establish and carry out the funding
policy and method of the Plan, which responsibilities are more specifically
described in this Plan and the Trust Agreement. The Committee shall have the
sole authority to appoint and remove any Investment Manager which may be
provided for under the Trust Agreement. The Trustee shall have the sole
responsibility for the administration of the Trust Fund and shall have exclusive
authority and discretion to manage and control the assets held under the Trust
Fund except to the extent that the authority to manage, acquire and dispose of
the assets of the Trust Fund is delegated to an Investment Manager, all as
specifically provided in the Trust Agreement. Each Fiduciary shall warrant that
any directions given, information furnished, or action taken by it shall be in
accordance with the 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 or 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.

         13.14    Annual Audit: The Committee shall engage, on behalf of all
Members, an independent Certified Public Accountant who shall conduct an annual
examination of any financial statements of the Plan and Trust Agreement and of
other books and records of the Plan and Trust Agreement as the Certified Public
Accountant may deem necessary to enable him to form and provide a written
opinion as to whether the financial statements and related schedules required to
be filed with the Internal Revenue Service or Department of Labor and furnished
to

<PAGE>

                                                                   EXHIBIT 10.51

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 Internal Revenue Service or 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 Internal Revenue Service or
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.

                                  ARTICLE XIV

                            CONTRIBUTIONS TO THE PLAN

         14.1     Member Contributions: Members are neither required nor
permitted to make contributions under the Plan.

         14.2     Employer Contributions: Each Employer shall contribute to the
Plan every year such amount as shall be actuarially determined to be sufficient
to fund the liability of the Plan. The amount of such contribution shall be
determined annually by the Committee following actuarial determination. The
Committee shall, prior to the fixing of the amount of contributions by the
respective Employers, cause such actuarial determination to be made by the
Actuary appointed by it but the fixing of the amount of contributions by the
Employers shall be made by the Committee after considering the recommendation of
such Actuary. In no event shall such annual contributions be less than the
minimum amount required by the minimum funding standard of ERISA. The provisions
of this Section 14.2 and Section 13.13 shall be deemed to be the procedure for
establishing and carrying on the funding policy and method of the Plan.

                  Contributions to the Trust Fund by any Employer shall be used
to pay benefits or to pay expenses of the Plan and Trust Fund; provided,
however, that upon the Employer's request, a contribution which was made by a
mistake of fact, or conditioned upon initial qualification of the Plan and Trust
Fund under Sections 401(a) and 501(a) of the Code, or upon the deductibility of
the contribution under Section 404 of said Code, shall be returned to the
Employer within one year after the payment of the contribution, the denial of
initial qualification or the disallowance of the deduction (to the extent
disallowed), whichever is applicable. Earnings attributable to any such excess
contribution may not be withdrawn, but losses attributable thereto must reduce
the amount to be returned. Except to the extent that an Employer expressly
states to the contrary in a writing to the Trustee at the time of making the
contribution to the Trust Fund, each contribution shall be presumed to have been
conditioned upon its deductibility.

         14.3     Discontinuance or Suspension of Contributions: Upon a complete
discontinuance of contributions by formal action of the board of directors of
any Employer, the Plan shall be terminated as to such Employer as of the
effective date of such discontinuance in accordance with Article XVII. If for
any year an Employer fails to make a contribution to the Trust Fund in
accordance with Section 14.2, and such failure constitutes a suspension of
contributions which either affects benefits to be paid or made available
hereunder or causes the unfunded past service cost at any time to exceed the
unfunded past service cost as of the effective date of the suspension of
contributions (plus any additional past service costs thereafter added by
amendment), then in either of such events, the Employer and the Trustee shall
each notify the appropriate District Director of Internal Revenue regarding such
suspension. During any such period of suspension, all other provisions of the
Plan shall continue in full force and effect, other than the provisions required
for contributions to the Trust Fund in accordance with Section 14.2. Upon
termination of the Plan or upon complete discontinuance of contributions by an
Employer, the right of each Member of the Employer to his accrued benefits to
the date of such termination or discontinuance, to the extent then funded, shall
be nonforfeitable, and the Employer shall promptly notify the appropriate
District Director of Internal Revenue and the Pension Benefit Guaranty
Corporation of such event.

         14.4     Forfeitures Credited Against Employer's Contributions: All
credits arising as a result of more favorable interest, mortality, turnover, or
other experience than has been assumed in the actuarial determination of cost
requirements, and all forfeitures by Members or Beneficiaries of Members arising
from any source whatsoever, shall be applied against the Employer's
contributions to be made pursuant to Section 14.2 hereof in subsequent years

<PAGE>

                                                                   EXHIBIT 10.51

in accordance with a method of funding approved by the U.S. Treasury Department,
and shall not be applied to increase the benefits that any Member or the
Beneficiary of any Member would otherwise receive under the Plan.

         14.5     Single Plan: The portion of the cost of providing the benefits
under this Plan shall be borne by each Employer for its own Members on an
equitable basis as determined by the Committee. Separate accounting may be
maintained for the purposes of cost allocation but not for the purposes of
providing benefits under the Plan, it being understood that, on an ongoing
basis, all of the Plan assets are available to pay benefits to all Members who
are covered by the Plan and their Spouses or Beneficiaries, regardless of which
Employer employed the Member.

                                   ARTICLE XV

                              AMENDMENT OF THE PLAN

         15.1     Right to Amend Reserved: Except as otherwise provided in
Section 15.2, (a) the Company shall have the right to amend or modify this Plan
and the Trust Agreement (with the consent of the Trustee, if required) at any
time and from time to time to the extent that it may deem advisable and (b) the
Committee shall have the right to amend or modify this Plan and the Trust
Agreement (with the consent of the Trustee, if required) to modify the
administrative provisions of the Plan and for any changes required by applicable
law or by the Internal Revenue Service to maintain the qualified status of the
Plan and related Trust at any time and from time to time to the extent that it
may deem advisable.

         15.2     Limitations on Right to Amend: No amendment of this Plan or
the Trust Agreement shall in any way impair or diminish the rights of Members,
retired Members, their Spouses or Beneficiaries and the contributions made by
the Employers and the Members prior to the date of such amendment, and no
amendment shall, at any time prior to the satisfaction of all liabilities with
respect to Members, retired Members, their Spouses and Beneficiaries under this
Plan, have the effect of diverting any part of the income or corpus of the Trust
Fund for purposes other than the exclusive benefit of such Members, retired
Members, Spouses and Beneficiaries.

                  No amendment shall directly or indirectly reduce a Member's
nonforfeitable vested percentage in his Accrued Benefit under this Plan, unless
each Member having not less than three years of Service is permitted to elect to
have his nonforfeitable vested percentage in his Accrued Benefit computed under
the Plan without regard to the amendment. Such election shall be available
during an election period, which shall begin on such date the amendment is
adopted, and shall end on the latest of (a) the date 60 days after such
amendment is adopted, (b) the date 60 days after such amendment is effective or
(c) the date 60 days after such Member is issued notice of the amendment by the
Committee or the Employer. If this Plan is amended and an effect of such
amendment is to increase current liability (as defined in Code Section
401(a)(29)(E)) under the Plan for a Plan Year, and the funded current liability
percentage of the Plan for the Plan Year in which the amendment takes effect is
less than 60%, including the amount of the unfunded current liability under the
Plan attributable to the amendment, the amendment shall not take effect until
the Employer (or any member of a controlled group which includes the Employer)
provides security to the Plan. The form and amount of such security shall
satisfy the requirements of Code Section 401(a)(29)(B) and (C). Such security
may be released provided the requirements of Code Section 401(a)(29)(D) are
satisfied.

                  Notwithstanding anything herein to the contrary, however, 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, as amended from
time to time, 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. The
duties, responsibilities, and liabilities of the Trustee may not be increased
without its written consent.

         15.3     Form of Amendment: Any such amendment or modification shall be
set out in an instrument in writing duly authorized by the Directors or the
Committee, as the case may be, and executed by an appropriate officer of the
Company or member of the Committee.

         15.4     Merger of Plan with Another Pension 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:

                  (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, and of any new or successor employer of the affected
         Members, shall authorize such transfer of assets; and in the case of a
         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.

                                  ARTICLE XVI
                         THE TRUSTEE AND THE TRUST FUND

         16.1     Trust Agreement: The Trust Agreement shall mean the Baker
Hughes Incorporated Retirement Plan Master Trust Agreement, between the Company
and the Trustee, for the benefit of this Plan; and the provisions of which are
herein incorporated by reference as fully as if set out herein; and the assets
held under said Trust Agreement on behalf of this Plan shall constitute the
Trust Fund.

         16.2     Benefits Paid Solely From Trust Fund: All benefits provided
under the Plan shall be paid out of the Trust Fund. The Employers shall not be
responsible or liable in any manner for payment of any such benefits, and all
Members shall look solely to the Trust Fund and to the adequacy thereof for the
payment of any such benefits of any nature or kind which may at any time be
payable hereunder.

         16.3     Trust Fund Applicable Only to Payment of Benefits: The Trust
Fund shall be used and applied only to provide the benefits of the Plan in
accordance with the provisions thereof. No part of the corpus or income of the
Trust Fund will be used for, or diverted to, purposes other than for the
exclusive benefit of Members, retired Members and their Beneficiaries, or for
the payment of reasonable expenses of the Plan, except as provided in Section
17.5.

         16.4     Accounting by Trustee: The Trustee shall keep proper accounts
of all investments, receipts, disbursements and other transactions effected by
it hereunder, and all accounts, books and records relating thereto shall be open
for inspection at all reasonable times by the Committee or by any other person
designated by the Company, but nothing herein contained shall be construed to
require the Trustee to maintain any record of the interests of the individual
Members in the Trust Fund. As of the close of each year (or more often, if
requested by the Company), the Trustee shall prepare and furnish to the
Employers and the Actuary an annual valuation of the Trust Fund, containing a
detailed statement of investments reflecting cost and market values, and a
statement of receipts and disbursements of the Trust Fund and other transactions
effected by it during such year.

         16.5     Authorization to Protect Trustee: Any action by the Company or
other Employer pursuant to any of the provisions of this Plan shall be evidenced
by a resolution of its board of directors certified to the Trustee over the
signature of its secretary or assistant secretary under its corporate seal or by
written instrument executed by any person authorized by said board of directors
to take such action.

         16.6     Exemption From Bond: The Trustee shall not be required to give
bond or other security for the faithful performance of its duties hereunder
unless otherwise required by law.

                                  ARTICLE XVII
                             TERMINATION OF THE PLAN

         17.1     Right to Terminate Reserved: The Plan has been established in
confidence that it will continue in effect indefinitely. However, due to the
uncertainties under which all business activity operates, the Company (and any
other Employer adopting the Plan in accordance with Article XVIII) must and
herewith does reserve the right to terminate the Plan on its own behalf, in
whole or in part, at any time. A termination of the Plan shall be evidenced by a
written instrument executed by the appropriate Employer on the order of its
board of directors and filed with the Committee and the Trustee. Termination of
the Plan shall be effective upon the date specified in such instrument
(hereinafter referred to as the "termination date"), but such termination shall
not vest in the terminating Employer any right, title, or interest in or to the
funds held hereunder nor shall it in any way deter the other participating
Employers from continuing the Plan for the benefit of their employees.

                  If the Plan is terminated by an Employer with respect to all
its Members, no further contribution shall be made to the Trust Fund by the
terminating Employer, no employees of the terminating Employer shall become
Members of the Plan after the termination date, and no further payments of
benefits with respect to Members employed by such terminating Employer
(including for all purposes of this Article, former Members and their
Beneficiaries) shall thereafter be made except in distribution of assets of the
Trust Fund as provided in Section 17.3. In the case of such termination, the
provisions of this Article shall apply only to Members employed by the
terminating Employer.

                  If the Plan is partially terminated only as to the designated
group of employees of a participating Employer, the Trust Fund shall be
allocated between the group of Members as to whom the Plan is terminated and the
remaining group of Members upon the basis of the funded actuarial requirements
of the Plan with respect to such groups, and the provisions of this Article
shall apply only to the group of Members employed by the Employer as to whom the
Plan is terminated and the part of the Trust Fund so allocated to such group.
The assets of such part of the Trust Fund shall be distributed as provided in
Section 17.3, however, only if the participating Employer does not direct such
part to be transferred to another fund or trust for the benefit of the group as
to whom the Plan is terminated, including but not limited to, a fund or trust
under another pension plan of the participating Employer or of another business
organization; provided, however, that no such transfer shall be made in
violation of Sections 15.4, 17.3 and 17.6.

                  Any termination (other than a partial termination or an
involuntary termination pursuant to ERISA Section 4042) must satisfy the
requirements and follow the procedures outlined in ERISA Section 4041 for a
"standard termination" or a "distress termination" as more fully described
therein. Upon a complete or partial termination of the Plan, each affected
Member's Accrued Benefit, based on his Service, Vesting Service and Compensation
prior to the date of such termination, shall become fully vested and
nonforfeitable to the extent then funded. In the event that the Plan is
partially terminated, the following provisions of this Article XVII shall apply
only to that part of the Plan so terminated. Any distribution made upon
termination of the Plan shall be subject to the distribution limitations
otherwise applicable under the Plan, specifically including the consent
provisions of Section 11.3.

         17.2     Continuance With Successor Employer: Upon an Employer's
liquidation, bankruptcy, insolvency, sale, consolidation or merger to or with
another organization that is not an Employer hereunder, in which such Employer
is not the surviving company, all obligations of that Employer hereunder and
under the Trust Agreement which had not theretofore been funded shall terminate
automatically, and the Trust Fund assets attributable to such Employer shall be
held or distributed as herein provided, unless, with the approval of the
Company, the successor to that Employer assumes the duties and responsibilities
of such Employer, by adopting this Plan and the Trust Agreement, or by
establishment of a separate plan and trust to which the assets of the Trust Fund
held on behalf of the Employees of such Employer shall be transferred with the
consent and agreement of that Employer. Upon the consolidation or merger of two
or more of the 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 Agreement of the Employers involved and their equitable
shares of the Trust Fund shall be merged and thereafter allocable to the
surviving Employer or organization for its employees and their beneficiaries.
Notwithstanding the above provisions of this Section 17.2, to the contrary, not
less than 30 days prior to any such merger, consolidation or transfer of Trust

<PAGE>

                                                                   EXHIBIT 10.51

Fund assets, the Committee shall file with the Commissioner of Internal Revenue
the actuarial statement of valuation required by Code Section 6058(b) evidencing
compliance with the requirements of Code Section 401(a)(12) and Section 15.4 of
the Plan.

         17.3     Liquidation of Trust Fund: Upon a full termination of the Plan
with respect to any Employer, a separation of the Trust Fund with respect to the
affected Members of such Employer shall be made as of the termination date in
accordance with the procedures set forth in Section 18.3. Thereafter, each
affected Member's Accrued Benefit based on his Service, Vesting Service, and
Compensation prior to the date of termination, to the extent then funded and
payable under the following provisions, shall become fully vested and the assets
of the Trust Fund attributable to Members of such terminated Employer shall be
allocated, after provision is made for the expenses of liquidating the Trust
Fund, among the Members receiving or holding the following benefits in the
following order:

                  (a)      First, to benefits payable on the termination date:

                           (i)      In the case of the benefit of a Member or
                  Beneficiary which was in pay status as of the beginning of the
                  three-year period ending on the termination date of the Plan,
                  to each such benefit, based on the provisions of the Plan (as
                  in effect during the five-year period ending on such date)
                  under which such benefit would be the least; and

                           (ii)     In the case of a retired Member's, a
                  disabled Member's or a Beneficiary's benefit (other than a
                  benefit described in clause (i) above) which would have been
                  in pay status as of the beginning of such three-year period if
                  the Member had retired prior to the beginning of the
                  three-year period and if his benefits had commenced (in the
                  normal form of pension under the Plan) as of the beginning of
                  such period, to each such benefit based on the provisions of
                  the Plan (as in effect during the five-year period ending on
                  such date) under which such benefit would be the least.

         For purposes of clause (i) of this subsection (a), the lowest benefit
         in pay status during a three-year period shall be considered the
         benefit in pay status for such period.

                  (b)      Second:

                           (i)      To all other benefits (if any) of
                  individuals under the Plan guaranteed under Title IV - Plan
                  Termination Insurance - of ERISA (determined without regard to
                  Section 4022(b)(5) thereof); and

                           (ii)     To the additional benefits (if any) which
                  would be determined under clause (i) immediately above if
                  Section 4022(b)(6) of ERISA did not apply.

         For purposes of this subsection (b), Section 4021 of ERISA shall be
         applied without regard to subsection (c) thereof.

                  (c)      Third, to all other nonforfeitable benefits under the
         Plan.

                  (d)      Fourth, to all other benefits under the Plan.

         If the assets available for allocation under subsection (a) or (b)
         above are insufficient to satisfy in full the benefits of all
         individuals which are described in such subsection, the assets shall be
         allocated pro rata among individuals on the basis of the present value
         (as of the termination date) of their respective benefits described in
         such subsection. If the assets available for allocation

<PAGE>

                                                                   EXHIBIT 10.51

         under subsection (c) or (d) above are not sufficient to satisfy in full
         the benefits or individuals described in such subsection, then:

                                    (1)      If this paragraph applies, except
                           as provided in subsection (B) below, the assets shall
                           be allocated to the benefits of individuals described
                           in subsection (c) on the basis of the benefits of
                           individuals which would have been described in such
                           subsection (c) under the Plan as in effect at the
                           beginning of the five-year period ending on the date
                           of Plan termination; and

                                    (2)      If the assets available for
                           allocation under subsection (A) are sufficient to
                           satisfy in full the benefits described in such
                           subsection (without regard to this subsection), then
                           for purposes of subsection (A), benefits of
                           individuals described in such subsection shall be
                           determined on the basis of the Plan as amended by the
                           most recent Plan amendment effective during such
                           five-year period under which the assets available for
                           allocation are sufficient to satisfy in full the
                           benefits of individuals described in subsection (A)
                           and any assets remaining to be allocated under such
                           subsection shall be allocated under subsection (A) on
                           the basis of the Plan as amended by the next
                           succeeding Plan amendment effective during such
                           period.

         17.4     Partial Termination: Upon termination of the Plan with respect
to a group of Members which constitutes a partial termination of the Plan, the
Employer shall cause the proportionate interest of the Members affected by such
partial termination to be determined. The determination of such proportionate
interest shall be done in an equitable manner, considering the remaining Members
as well as the Members affected by the termination, and on the basis of the
contributions made by the Employer, the provisions of this Article XVII and
other appropriate considerations. After such proportionate interest has been
determined, the assets of the Trust Fund shall be allocated and segregated
according to such proportionate interest. The assets of the Trust Fund so
allocated and segregated shall be used to pay benefits to or on behalf of
Members in accordance with this Article XVII.

         17.5     Distribution of Trust Fund: Any distribution after full
termination of the Plan may be made in whole or in part, to the extent that no
discrimination in value results, in cash, securities, or other assets in kind,
or in annuity contracts, as the Committee, in its discretion, acting under the
advice of the Actuary, shall determine. The benefits as apportioned pursuant to
Section 17.3 above may be provided:

                  (a)      By the continuation of the Trust Fund for the payment
         of all or such of the benefits as are within the limits prescribed by
         the Committee and acceptable by the Trustee;

                  (b)      Through the purchase of annuities from one or more
         insurance companies with the amount of the benefit equal to the Accrued
         Benefit equal to the Actuarial Equivalent (determined by use of the
         interest rate used by the Pension Benefit Guaranty Corporation for
         determining the present value of a lump-sum distribution on plan
         termination) of each Member's benefit;

                  (c)      By distribution in a single sum of the Actuarial
         Equivalent (determined by use of the interest rate used by the Pension
         Benefit Guaranty Corporation for determining the present value of a
         lump-sum distribution on plan termination) of each Member's Accrued
         Benefit; or

                  (d)      By any combination of (a), (b) and (c).

<PAGE>

                                                                   EXHIBIT 10.51

In making such distributions, any and all determinations, divisions, appraisals,
apportionments and allotments so made shall be final and conclusive and shall
not be subject to question by any person. Any annuity contract distributed by
the Trustee to a Member under subsection (b) above or under any other provision
of this Plan shall bear on the face thereof a designation "Not Transferable,"
and such annuity contract shall expressly provide that the contract may not be
sold, assigned, discounted or pledged as collateral for a loan or as security
for the performance of an obligation or for any other purpose to any person
other than the issuer thereof. Notwithstanding the foregoing, the Employer shall
promptly advise the appropriate District Director of Internal Revenue and the
Pension Benefit Guaranty Corporation of the termination and shall direct the
Trustee to delay the final distribution to Members until said District Director
shall advise in writing that such termination does not adversely affect the
previously qualified status of the Plan or the exemption from tax of the Trust
Agreement under Section 401(a) or 501(a) of the Code and the Pension Benefit
Guaranty Corporation has approved the proposed termination distribution or made
any appropriate requirements concerning same. 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.

         17.6     Residual Amounts: In no event shall any Employer receive any
amounts from the Trust Fund except that upon termination of the Plan, and
notwithstanding any other provision of the Plan, an Employer shall receive such
amounts, if any, as may remain in the Trust Fund because of erroneous actuarial
computation as defined in Treasury Regulations.

         17.7     Limitations Imposed by Treasury Regulations Upon Early
Termination of Plan: In the event the Plan is terminated by any Employer for any
reason during the first 10 years after the original effective date of the Plan
("Original Effective Date"), and if full current costs had not been met with
respect to any Employer at the end of the first 10 years, until said full
current costs are met, then notwithstanding any provision in this Plan to the
contrary, the benefits provided by the Employer's contributions for the Members
whose anticipated annual retirement benefit at Normal Retirement Date exceeds
$1,500 and who on the Original Effective Date were among the 25 highest paid
Employees of the Employer will be subject to the conditions set forth in the
following provisions:

                  (a)      The benefit payable to a Member described in this
         Section or his Beneficiary shall not exceed the greater of the
         following:

                           (i)      those benefits purchasable by the greater of
                  (A) $20,000, or (B) an amount equal to 20% of the first
                  $50,000 of the Member's annual Compensation multiplied by the
                  number of years from the Original Effective Date to the
                  earlier of (1) the date of termination of the Plan, (2) the
                  date the benefit of the Member becomes payable or (3) the date
                  of a failure on the part of the Employer to meet the full
                  current costs of the Plan; or

                           (ii)     if a Member is a "substantial owner" (as
                  defined in Section 4022(b)(5)(A) of ERISA), the present value
                  of the benefit guaranteed for "substantial owners" under
                  Section 4022 of ERISA; or

                           (iii)    if the Member is not a "substantial owner,"
                  the present value of the maximum benefit provided in Section
                  4022(b)(3)(B) of ERISA, determined on the date the Plan
                  terminates or on the date benefits commence, whichever is
                  earlier, and in accordance with regulations of the Pension
                  Benefit Guaranty Corporation.

                  (b)      If the Plan is terminated or the full current costs
         thereof have not been met at any time within 10 years after the
         Original Effective Date, the benefits which any of the Members
         described in this Section may receive from the Employer's contribution
         shall not exceed the benefits set forth in this Section 17.7. If at the
         end of the first 10 years the full current costs are not met, the
         restrictions will continue to apply until the full current costs are
         funded for the first time.

                  (c)      If a Member described in this Section leaves the
         employ of the Employer or withdraws from participation in the Plan when
         the full current costs have been met, the benefits which he may receive
         from the Employer contributions shall not at any time within the first
         10 years after the Original Effective Date exceed the benefits set
         forth in this Section 17.7.

                  (d)      These conditions shall not restrict the full payment
         of any survivor's benefits on behalf of a Member who dies while in the
         Plan and the full current costs have been met.

                  (e)      These conditions shall not restrict the current
         payment of full retirement benefits called for by the Plan for any
         retired Member while the Plan is in full effect and its full current
         costs have been met, provided an agreement, adequately secured,
         guarantees the repayment of any part of the distribution that is or may
         become restricted.

                  (f)      If the benefits of, or with respect to, any Member
         shall have been suspended or limited in accordance with the limitations
         of this Section 17.7 because the full current costs of the Plan shall
         not then have been met, and if such full current costs shall thereafter
         be met, then the full amount of the benefits payable to such Member
         shall be resumed and the parts of such benefits which have been
         suspended shall then be paid in full.

                  (g)      Notwithstanding anything in this Section 17.7, if on
         the termination of the Plan within the first 10 years after the
         Original Effective Date, the funds, contracts, or other property under
         the Plan are more than sufficient to provide pensions for Members and
         their Beneficiaries including full benefits for all Members other than
         such of the 25 highest paid Employees as are still in the service of
         the Employer and also including Accrued Benefits as limited by this
         Section for such 25 highest paid Employees, then any excess of such
         funds, contracts, and property shall be used to provide Accrued
         Benefits for the 25 highest paid Employees in excess of such
         limitations of this Section up to the benefits to which such Employees
         would be entitled under this Plan without such limitations.

                  (h)      In the event that Congress should provide by statute,
         or the Treasury Department or the Internal Revenue Service should
         provide by regulation or ruling, that the limitations provided for in
         this Section 17.7 are no longer necessary in order to meet the
         requirements for a qualified pension plan under the Code as then in
         effect, the limitations in this Section 17.7 shall become void and
         shall no longer apply without the necessity of amendment to this Plan.

                  (i)      In the event a lump-sum distribution is made to an
         Employee subject to the above restrictions in an amount in excess of
         that amount otherwise permitted under this Section 17.7, an agreement
         shall be made, with adequate security guaranteeing repayment of any
         amount of the distribution that is restricted. Adequate security shall
         mean property having a fair market value of at least 125% of the amount
         which would be repayable if the Plan had terminated on the date of
         distribution of such lump sum. If the fair market value of the property
         falls below 110% of the amount which would then be repayable if the
         Plan were then to terminate, the distributee shall deposit additional
         property to bring the value of the property to 125% of such amount.

Notwithstanding the foregoing, the following provisions are applicable in the
event of an early plan termination rather than the foregoing provisions of this
Section 17.7. In the event of an early plan termination, the benefit of any
highly compensated active or former Employee is limited to a benefit that is
nondiscriminatory under Section 401(a)(4). In the event of early plan
termination, benefits distributed to any of the 25 most highly compensated
active and highly compensated former Employees with the greatest Compensation in
the current or any prior year are restricted such that the annual payments are
no greater than an amount equal to the payment that would be made on behalf of
the Employee under a straight life annuity that is the actuarial equivalent of
the sum of the Employee's Accrued Benefit, the Employee's other benefits under
the Plan (other than a social security supplement, within the meaning of
Treasury Regulations Section 1.411(a)-7(c)(4)(ii)), and the amount the Employee
is entitled to receive under a social security supplement.

                  The preceding paragraph shall not apply if: (i) after payment
of the benefit to an Employee described in the preceding paragraph, the value of
Plan assets equals or exceeds 110% of the value of current liabilities, as
defined in Section 412(l)(7) of the Code, (ii) the value of the benefits for an
Employee described above is less than 1% of the value of current liabilities
before distribution, or (iii) the value of the benefits payable under the Plan
to an Employee described above does not exceed $5,000.

                  For purposes of this Section, benefit includes loans in excess
of the amount set forth in Section 72(p)(2)(A) of the Code, any periodic income,
any withdrawal values payable to a living Employee, and any death benefits not
provided for by insurance on the Employee's life.

                                 ARTICLE XVIII
                               ADOPTING EMPLOYERS

         18.1     Designation of Other Employers(a) The Directors may designate
         by written instrument any entity or organization eligible by law to
         participate in the Plan and the Trust as an Employer. Such written
         instrument shall specify the effective date of such designated
         participation, may incorporate specific provisions relating to the
         operation of the Plan that apply to the designated Employer only and
         shall become, as to such designated Employer and its Employees, a part
         of the Plan.

                  (b)      Each designated Employer shall be conclusively
         presumed to have consented to its designation and to have agreed to be
         bound by the terms of the Plan and any and all amendments thereto upon
         its submission of information to the Committee required by the terms of
         or with respect to the Plan or upon making a contribution to the Trust
         Fund pursuant to the terms of the Plan; provided, however, that the
         terms of the Plan may be modified so as to increase the obligations of
         an Employer only with the consent of such Employer, which consent shall
         be conclusively presumed to have been given by such Employer upon its
         submission of any information to the Committee required by the terms of
         or with respect to the Plan or upon making a contribution to the Trust
         Fund pursuant to the terms of the Plan following notice of such
         modification.

                  (c)      The provisions of the Plan shall apply separately and
         equally to each Employer and its Employees in the same manner as is
         expressly provided for the Company and its Employees, except that the
         power to appoint or otherwise affect the Committee or the Trustee and
         the power to amend or terminate the Plan and Trust Agreement shall be
         exercised by the Company, the Directors, or the Committee, as
         applicable, alone.

                  (d)      Transfer of employment among Employers shall not be
         considered a termination of employment hereunder, and Service with one
         shall be considered as Service with all others.

                  (e)      The above notwithstanding, any action that may be
         taken by the Directors pursuant to this Section may also be taken by
         the Committee.

         18.2     Single Plan: For purposes of the Code and the Act, the Plan as
adopted by the Employers shall constitute a single plan rather than a separate
plan of each Employer. All assets in the Trust Fund shall be available to pay
benefits to all Members and their beneficiaries.

                                   ARTICLE XIX
                                  MISCELLANEOUS

         19.1     Plan Not an Employment Contract: The adoption and maintenance
of the Plan shall not be deemed to constitute a contract between an Employer and
any Member, and shall not be deemed to be consideration for, inducement to, or a
condition of employment of any person. Nothing herein contained shall be
construed to give any Member the right to be retained in the employment of an
Employer or to interfere with the right of an Employer to terminate the
employment of any Member at any time.

                                                                   EXHIBIT 10.51

         19.2     Controlling Law: Subject to the provisions of ERISA, as the
same may be amended from time to time, which may be applicable and provide to
the contrary, this Plan shall be construed, regulated and administered under the
laws of the State of Texas.

         19.3     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.

         19.4     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, benefits payable under this Plan shall not be subject in
any manner to anticipation, alienation, sale, transfer, assignment, pledge,
encumbrance, charge, garnishment, execution or levy of any kind, either
voluntary or involuntary. The preceding sentence shall also apply to the
creation, assignment or recognition of a right to any benefit payable with
respect to a Member pursuant to a domestic relations order unless such order is
determined by the Committee to be a qualified domestic relations order, as
defined in Section 414(p) of the Code. If the Committee receives a qualified
domestic relations order with respect to a Member, the amount assigned to the
Member's former spouse may be immediately distributed, to the extent permitted
by law, from the vested portion of the benefit payable to the Member.

         19.5     Copy Available to Members: A copy of this Plan and Trust
Agreement and of any and all future amendments thereto shall be available to
Members and their Beneficiaries for inspection at all reasonable times. In
addition thereto, the Company shall print and distribute to all Employees a
pamphlet setting forth the terms of the Plan or a summary of the principal
provisions thereof.

         19.6     Evidence Furnished Conclusive: Each Employer, the Committee
and any person or persons involved in the administration of the Plan shall be
entitled to rely upon any certification, statement, or representation made or
evidence furnished by an Employee, Member or Beneficiary with respect to his
age, or other 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 Employee, Member or Beneficiary but not upon
an Employer, the Committee, or any other person or persons involved in the
administration of the Plan. 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 Employee, Member, or Beneficiary
from the duty of submitting satisfactory proof of his age or such other fact.

         19.7     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 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, whichever is later; provided, however, that such forfeited
benefits shall be reinstated if a claim for the same is made by the Member,
Beneficiary or other distributee at any time thereafter.

         19.8     Name and Address Changes: Each Member and each Beneficiary of
a deceased Member shall at all times be responsible for notifying the Committee
of any change in his name or address. If any check in payment of a benefit
hereunder (which was mailed to the last address of the payee as shown on the
Committee's records) is returned unclaimed, further payments shall be
discontinued until the Committee directs otherwise.

         19.9     Payments in Satisfaction of Claims of Members: Any payment or
distribution to any Member or his legal representative or 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 Committee, the Trustee and the
Employer.

                                                                   EXHIBIT 10.51

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

         19.11    Payments to 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
power to cause the payments becoming due to such person to be made to the
guardian of the minor or the guardian of the estate of the incompetent, or to
the County Clerk as allowed for under law without the Committee or the Trustee
being responsible to see to the application of such payment. Payments made
pursuant to such power shall operate as a complete discharge of the Committee,
the Trustee, the Employer and any Affiliate.

         19.12    Member Information: All persons entitled to benefits under the
Plan must furnish to the Committee or the Trustee such documents, evidence, or
information as the Committee or the Trustee considers necessary or desirable for
the purpose of administering the Plan or Trust, or to protect the Committee or
the Trustee; and it shall be a condition of the Plan that each such person must
furnish promptly true and complete data, evidence, or information and sign such
documents as the Committee or the Trustee may require before any benefits become
payable under the Plan. In the event that any data so furnished is found by the
Committee, the Trustee or the Company to be incorrect, or if the Committee, the
Trustee or the Company subsequently discovers any other error in the
determination of the original benefit amount payable, any overpayments made to
the Member or Beneficiary must be repaid to the Trust by such Member or
Beneficiary in a timely manner, and any underpayments shall be adjusted for on
an actuarial basis and paid to the Member or Beneficiary.

                                   ARTICLE XX
                           TOP-HEAVY PLAN REQUIREMENTS

         20.1     General Rule: For any Plan Year for which this Plan is a
Top-Heavy Plan, as defined in Section 20.7, any other provisions of this Plan to
the contrary notwithstanding, this Plan shall be subject to the provisions of
this Article XX.

         20.2     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 Service specified in the following table shall be vested in
his Accrued Benefit under this Plan at least as rapidly as is provided in the
following schedule; except that the vesting provision set forth in Section 5.1
shall be used at any time in which it provides for more rapid vesting:

<TABLE>
<CAPTION>
Years of Service                      Vested Percentage
----------------                      -----------------
<S>                                   <C>
Less than 2 years                             0%
2 but less than 3 years                      20%
3 but less than 4 years                      40%
4 but less than 5 years                      60%
5 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, except that each Member whose nonforfeitable
percentage of his Accrued Benefit derived from employer contributions is
determined under such amended schedule, and who has completed at least three
years of service with the employer, may elect, during the election period, to
have the nonforfeitable percentage of his Accrued Benefit derived from employer
contributions determined without regard to such amendment if his nonforfeitable
percentage under the Plan as amended is, at any time, less than such percentage
determined without regard to such amendment. For all other Members, the
nonforfeitable percentage of their Accrued Benefit prior to the date the Plan
ceased to be top heavy shall not be reduced, but future increases in the
nonforfeitable percentage shall be made only in accordance with Section 5.1.

<PAGE>

                                                                   EXHIBIT 10.51

         20.3     Minimum Benefit Provisions: Each Member who is a Non-Key
Employee, as defined in Section 20.8, shall be entitled to an Accrued Benefit in
the form of a single-life annuity (with no ancillary benefits) beginning at his
Normal Retirement Date, that shall not be less than his average annual Member's
Compensation, within the meaning of Code Section 415, for years in the Testing
Period multiplied by the lesser of: (a) 2% multiplied by the number of years of
Top-Heavy Service or (b) 20%. A Non-Key Employee may not fail to receive a
minimum benefit because of a failure to receive a specified amount of
Compensation or a failure to make mandatory employee or elective contributions.

                  "Testing Period" means, with respect to a Member, the period
of consecutive years of Top-Heavy Service, not exceeding five, during which the
Member had the greatest aggregate compensation, within the meaning of Code
Section 415, from the Company. "Top-Heavy Service" means his Service credited
under Article III. Top-Heavy Service shall not include any Service before July
1, 1984 or any Service that begins after the close of the last Plan Year in
which the Plan was a Top-Heavy Plan. Years before and after such excluded
periods shall be considered consecutive for purposes of determining the Testing
Period.

         20.4     Limitation on Compensation: A Member's annual Compensation
taken into account under this Article XX for purposes of computing benefits
under this Plan for any Plan Year shall not be in excess of $200,000. 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.

         20.5     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 applicable principles
prescribed by Treasury Regulations or applicable IRS rulings (such as Revenue
Ruling 81-202 or any successor ruling) to determine whether this Plan satisfies
the requirements of Sections 20.2, 20.3 and 20.4 and to avoid inappropriate
omissions or inappropriate duplication of minimum contributions. Such
determination shall be made upon the advice of counsel by the Committee. In the
event a Member is covered by a defined benefit plan which is top-heavy pursuant
to Section 416 of the Code, 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.

         20.6     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)(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.

         20.7     Determination of Top-Heavy Status: The Plan shall be a
Top-Heavy Plan for any Plan Year if, as of the Determination Date, the present
value of the cumulative Accrued Benefits under the Plan determined as of the
Valuation Date for Members (including former Members) who are Key Employees
exceeds 60% of the present value of the cumulative accrued benefits under the
Plan for all Members (including former Members) 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
one-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. The Accrued Benefit of any employee (other than a Key Employee) shall
be determined under (a) the method, if any, that uniformly applies for accrual
purposes under all plans maintained by the Aggregation Group or (b) if there is
no such method, as if such benefit accrued not more rapidly than the slowest
accrual rate permitted under the fractional accrual rate of Code Section
411(b)(1)(C).

                  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 that is required to be aggregated
         and the group of plans that is permitted to be

<PAGE>

                                                                   EXHIBIT 10.51

         aggregated. The group of plans that is required to be aggregated (the
         "required aggregation group") includes:

                           (i)      Each plan of a Considered Company in which a
                  Key Employee is a member, including collectively bargained
                  plans; and

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

         The group of plans that is permitted to be aggregated (the "permissive
         aggregation group") includes the required aggregation group and any
         plan that is not part of the required aggregation group that the
         Committee certifies as constituting a plan within the permissive
         aggregation group. Such plans may be added to the permissive
         aggregation group only if, after the addition, the aggregation group as
         a whole continues to meet the requirements of both Code Sections
         401(a)(4) and 410.

                  (b)      "Considered Company" means the Company, other
         Employer or an Affiliate.

                  (c)      "Determination Date" means for any Plan Year the last
         day of the immediately preceding Plan Year or in the case of the first
         Plan Year of the Plan, Determination Date means the last day of such
         Plan Year.

                  (d)      "Key Employee" as defined in Code Section 416(i)(1)
         means any Employee or former Employee who at any time during the Plan
         Year containing the Determination Date is (1) an officer of the
         Employer having annual compensation greater than $130,000 (as adjusted
         under Code Section 416(i)(1) for Plan years beginning after December
         31, 2001); (2) a 5% owner of the Employer; or (3) a 1% owner of the
         Employer who has annual compensation of more than $150,000. For
         purposes of this subsection (d), "annual compensation" means
         compensation within the meaning of Code Section 415(c)(3). For purposes
         of determining 5% and 1% owners, (a) an "owner" means (i) if the
         employer is a corporation, any person who owns (or is considered as
         owning under Code Section 318) more than 5% or 1%, respectively, of the
         corporation's outstanding stock or stock possessing more than 5% or 1%,
         respectively, of the total combined voting power of all stock of the
         corporation, or (ii) if the employer is not a corporation, any person
         who owns more than 5% or 1%, respectively, of the capital or profits
         interest of the employer; and (b) neither the aggregation rules nor the
         rules of subsections (b), (c) and (m) of Code Section 414 apply.
         Beneficiaries of an Employee acquire the character of the Employee who
         performed service for the Employer. Also, inherited benefits will
         retain the character of the benefits of the Employee who performed
         services for the Employer.

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

                  (f)      "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 one-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 permissive

<PAGE>

                                                                   EXHIBIT 10.51

         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 in
         connection therewith:

                           (i)     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, and if such assumptions are not
                  set forth in the applicable plan, using the assumptions set
                  forth in this 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.

                           (ii)    In determining the present value of the
                  cumulative Accrued Benefit (for this purpose using the
                  actuarial assumptions set forth in Section 1.2 hereof) 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 one-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 which represented the entire amount credited to
                  their accounts under the applicable plan.

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

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

                                    (B)      If the rollover contribution (or
                           similar transfer) is not initiated by the employee or
                           made from a plan maintained by a Considered Company,
                           the plan accepting the distribution shall include
                           such distribution in the present value or 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 or such account.

                           (iv)     Further, in making such determination, 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.

                  (g)      "Valuation Date" means for purposes of 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 as if the individual (i) terminated service
         as of the Determination Date or (ii) 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.

                  (h)      For purposes of this Article, "Compensation" shall
         have the meaning given to it in Section 21.3(d) of the Plan.

                                  ARTICLE XXI
                             LIMITATION ON BENEFITS

                  Notwithstanding any provision of this Plan to the contrary,
the total Annual Benefit received by an Employee shall be subject to the
following limitations:

         21.1     Single Defined Benefit Plan:The annual normal retirement
benefit of any Employee under this Plan cannot exceed the lesser of $160,000
(increased annually for Limitation Years in accordance with Section 415(d) of
the Code to reflect cost-of-living adjustments) (the "Dollar Limitation") or
100% of such Employee's Average Compensation ("Percentage Limitation"). For
purposes of determining whether an Employee's benefits exceed these limitations,
the following rules shall apply:

                  (a)      Adjustment for Certain Other Forms of Benefit. If the
         normal form of benefit is other than a Single Life Annuity, such form
         must be adjusted actuarially to the equivalent of a Single Life
         Annuity; provided, however, that, subsection (d) of this Section
         notwithstanding, for a form of benefit subject to the adjustment
         required under Code Section 415(b)(2), the interest rate used to make
         such adjustment shall not be less than the "applicable interest rate"
         as defined in Code Section 417(e)(3) and the mortality table shall be
         that prescribed in Revenue Ruling 2001-62. This Single Life Annuity
         cannot exceed the maximum Dollar Limitation or Percentage Limitation
         outlined above. No adjustment is required for the following: qualified
         joint and survivor annuity benefits, pre-retirement disability
         benefits, pre-retirement death benefits and post-retirement medical
         benefits.

                  (b)      Adjustment To Dollar Limitation If Benefit Commences
         Before Age 62. If benefit distributions commence before a Member
         attains age 62, the Dollar Limitation shall be reduced, in accordance
         with regulations prescribed by the Secretary of the Treasury, so that
         it is the Actuarial Equivalent of the Dollar Limitation beginning at
         age 62. For purposes of this adjustment, the Actuarial Equivalent shall
         be based on subsection (b) of Section 1.2 of this Plan and subject to
         subsection (d) of this Section.

                  (c)      Adjustment To Dollar Limitation If Benefit Commences
         After Age 65.If benefit distributions commence after a Member reaches
         age 65, the Dollar Limitation shall be increased, in accordance with
         regulations prescribed by the Secretary of the Treasury, so that it is
         the Actuarial Equivalent of the Dollar Limitation beginning at age 65.
         For purposes of this adjustment, the Actuarial Equivalent shall be
         based on subsection (b) of Section 1.2 of this Plan and subject to
         subsection (d) of this Section.

                  (d)      Interest Assumption.The interest rate used for
         adjusting the maximum limitations above shall be:

                           (i)      For benefits commencing before age 62 and
                  for forms of benefit other than straight life annuity, the
                  greater of:

                                   (1)       5%; or

                                   (2)       the rate used to determine the
                           Actuarial Equivalent under subsection (b) of Section
                           1.2 of this Plan.

                           (ii)     For benefits commencing after age 65, the
                  lesser of:

                                   (1)       5%; or

                                                                   EXHIBIT 10.51

                                   (2)       the rate used to determine the
                           Actuarial Equivalent under subsection (b) of Section
                           1.2 of this Plan.

                  (e)      Reduction For Service Less Than 10 Years.In the case
         of an Employee who has less than 10 years of participation in a defined
         benefit plan of the Employer, the benefits shall not exceed the limit
         set forth in Article XXI above multiplied by a fraction, the numerator
         of which is the number of years (or part thereof) of participation in a
         defined benefit plan of the Employer and the denominator of which is
         10.

                  (f)      Adjustment For Small Benefits. In the case of an
         Employee whose Annual Benefit is not in excess of $10,000, the benefits
         payable with respect to such Employee under this Plan shall be deemed
         not to exceed the limitations of this Section if:

                           (i)      The Annual Benefits payable with respect to
                  such Employee under this Plan and all other defined benefit
                  plans of the Employer do not exceed $10,000 for the Plan Year
                  or for any prior Plan Year; and

                           (ii)     The Employer has not at any time maintained
                  a defined contribution plan in which the Employee
                  participated.

                  (g)      Protected Accrued Benefit.In the case of an
         individual who was a participant in one or more defined benefit plans
         of the Employer as of the first day of the first Limitation Year
         beginning after December 31, 1986, the application of the limitation of
         this Article XXI shall not cause the maximum permissible amount for
         such individual under all such defined benefit plans to be less than
         the individual's current Accrued Benefit. The preceding sentence
         applies only if such defined benefit plans met the requirements of Code
         Section 415 for all Limitation Years beginning before January 1, 1987.

         21.2     Two or More Defined Benefit PlansIf the Employer maintains one
or more defined benefit plans in addition to this Plan, the sum of the normal
retirement benefits of all plans will be treated as a single benefit for the
purposes of applying the limitations in Article XXI. If these benefits exceed,
in the aggregate, the limitations in Article XXI, the annual normal retirement
benefit under this Plan shall be reduced (but not below zero) until the sum of
the annual benefits of the remaining plans satisfy the limitations.

         21.3     Definitions

                  (a)      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 Code Section 414(b)
         as modified by Code Section 415(h)) or which constitutes trades and
         businesses (whether or not incorporated) which are under common control
         (as defined in Code Section 414(c) as modified by Code Section 415(h))
         or an affiliated service group (as defined in Code Section 414(m)), all
         such employers shall be considered a single Employer for purposes of
         applying the limitations of this Section.

                  (b)      Excess Amount: The excess of the Employee's Annual
         Additions for the Limitation Year over the Maximum Permissible Amount.

                  (c)      Limitation Year: A 12 consecutive month period ending
         on December 31.

                  (d)      Compensation: For purposes of determining compliance
         with the limitations of Code Section 415, Compensation shall mean an
         Employee'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 to salesmen,
         compensation for services based on a percentage of profits, commissions
         on insurance premiums, tips and bonuses, and excluding the following:

                           (i)      Employer contributions to a plan of 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
                  nonqualified plan may be considered as Compensation in the
                  year such amounts are included in the gross income of the
                  Employee);

                           (ii)     amounts realized from the exercise of a
                  nonqualified 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;

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

                           (iv)     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 an
                  annuity contract described under Code Section 403(b) (whether
                  or not the contributions are excludable from the gross income
                  of the Employee).

         For purposes of applying the limitations in this Article, amounts
         included as Compensation are those actually paid or made available to
         an Employee within the Limitation Year. Compensation shall be limited
         to $200,000 (unless adjusted in the same manner as permitted under Code
         Section 415(d)). Notwithstanding anything to the contrary in the
         definition, Compensation shall include any and all items which may be
         includable in Compensation under Section 415(c)(3) of the Code,
         including (i) any elective deferrals (as defined in Code Section
         402(g)(3)) and (ii) any amounts which are contributed or deferred by
         the Employer at the election of the Member or Employee and which are
         not includable with the gross income of the Member or Employee by
         reason of Code Section 125, 457 or 132(f)(4).

                  (e)      Average Compensation: The average Compensation during
         an Employee's high three years of service, which period is the three
         consecutive calendar years (or, the actual number of consecutive years
         of employment for those Employees who are employed for less than three
         consecutive years with the Employer) during which the Employee had the
         greatest aggregate Compensation from the Employer.

                  (f)      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.

         THIS AGREEMENT by Baker Hughes Incorporated, a Delaware corporation
(the "Company"),

                              W I T N E S S E T H:

         WHEREAS, the Company maintains the Baker Hughes Incorporated Pension

         WHEREAS, the Company desires to amend the Plan to comply with new legal
requirements;

         NOW, THEREFORE, the Company agrees as follows:

         distribution is required to be made to a Member or former Member under
         section 401(a)(9) of the Code and Department of Treasury Regulations
         thereunder. If a Member's or former Member's Required Beginning Date is
         April 1 of the calendar year following the calendar year in which he
         attains age 70 1/2, his first Distribution Calendar Year is the

         Member's Required Beginning Date is April 1 of the calendar year
         following the calendar year in which a Member's Termination of
         Employment occurs, his first Distribution Calendar Year is the calendar
         year in which his Termination of Employment occurs.

         Final Section 401(a)(9) Regulations: The final Department of Treasury
         Regulations issued under section 401(a)(9) of the Code which were

         in section 416(i) of the Code.

         Qualified Domestic Relations Order: A domestic relations order which
         the Plan Administrator has determined constitutes a qualified domestic
         relations order within the meaning of section 414(p) of the Code.

         Section 401(a)(9) Beneficiary: An individual who is a Member's or
         former Member's Beneficiary on the date of the Member's or former
         Member's death and (unless the Beneficiary dies after the date of the

         following calendar year without disclaiming benefits under the Plan)
         who remains a Beneficiary as of September 30 of the calendar year
         following the calendar year of the Member's or former Member's death.
         If the Member's or former Member's Beneficiary is a trust, an
         individual beneficiary of the trust may be a Section 401(a)(9)

         same extent any current spouse of the Member or former Member will not
         be treated as a Spouse of the Member or former Member. For purposes of
         Section 11.7, a former Spouse to whom all or a portion of a Member's or
         former Member's Plan benefit is payable under a Qualified Domestic
         Order shall, to that extent, be treated as a Spouse or surviving Spouse
         regardless of whether the Qualified Domestic Relations Order
         specifically provides that the former Spouse is to be treated as the
         Spouse for purposes of sections 401(a)(11) and 417 of the Code.

         if (a) his Severance From Service Date is on or after his Early
         Retirement Date or the date he attains age 65 or (b) his Service
         terminates due to his death or his becoming Totally Disabled."

3.       SECTION 11.1. Paragraph (b) of Section 11.1 shall be deleted and

                  "11.1 Payment of Accrued Benefit: Anything to the contrary
         notwithstanding, a Member's Accrued Benefit under this Plan shall be
         payable in accordance with the provisions of this Section. A Member who
         terminates his employment with all Employers and Affiliates and who has
         a vested right to an Accrued Benefit under the Plan may elect to
         commence payment of his Accrued Benefit as of his Early Retirement Date
         or his Normal Retirement Date. The distribution of his Accrued Benefit
         shall begin no later than the 60th day after the latest of the close of
         the year in which (i) the Member attains age 65 or (ii) the Member

         contrary, if a Member's Accrued Benefit has not commenced by the end of
         the Plan Year during which occurs his Normal Retirement Date, such
         Member's Accrued Benefit shall not be actuarially increased to reflect
         the delay in commencement in his Accrued Benefit after his Normal
         Retirement Date, in accordance with Section 203(a)(3) of ERISA and Code
         Section 411(b)(1)(H), and the applicable Department of Treasury
         Regulations."

4.       SECTION 11.6. Paragraphs (a) and (b) of Section 11.6 shall be amended
         in their entirety to provide as follows:

         of the Code, (4) a qualified plan described in section 401(a) of the

         the Code.

         (b) "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: (1) any

         the Eligible Retirement Plan to which the distribution is transferred
         (A) agrees to separately account for amounts so transferred, including
         separately accounting for the portion of such distribution which is not
         includable in gross income or (B) is an individual retirement account

5.       ARTICLE XI. Article XI of the Plan shall be amended by adding the
         following new Section 11.7:

                  "11.7 Required Distributions and Distribution Deadlines.
         Notwithstanding any other provision of the Plan, all benefits payable
         under the Plan shall be distributed, or commence to be distributed, in
         compliance with the following provisions:

                           (a) Required Distributions for Certain Persons Who
                  are 70 1/2 or Older. A Member's or former Member's entire
                  nonforfeitable interest in his Plan benefit must be
                  distributed to him in a single sum no later than his Required
                  Beginning Date, or must be distributed, beginning not later
                  than his Required Beginning Date, over the life of the Member
                  or former Member, or the joint lives of the Member or former
                  Member and his Section 401(a)(9) Beneficiary, or over a period
                  not extending beyond the life expectancy of the Member or
                  former Member or the joint and last survivor expectancy of the
                  Member or former Member and his Section 401(a)(9) Beneficiary.
                  The distribution required to be made on or before the Member's
                  or former Member's Required Beginning Date shall be the
                  distribution required for his first Distribution Calendar
                  Year. The minimum required distribution for other Distribution
                  Calendar Years, including the required minimum distribution
                  for the Distribution Calendar Year in which the Member's or
                  former Member's Required Beginning Date occurs must be made on
                  or before December 31st of that Distribution Calendar Year. In
                  the case of a benefit payable in a form other than a single
                  sum or an annuity purchased from an insurance company, the
                  amount that must be distributed for a Distribution Calendar
                  Year is an amount equal to the payment that is required for
                  one payment interval as specified in paragraphs (b), (c) and
                  (d) of this Section 11.7.

                           (b) Amount Required to be Distributed by Required
                  Beginning Date in the Case of Annuity Payments From the Plan.
                  The amount that must be distributed on or before the Member's
                  or former Member's Required Beginning Date (or, if the Member
                  or former Member dies before his Required Beginning Date, the
                  date distributions are required to begin under Section
                  11.7(e)) is the payment that is required for one payment
                  interval. The second payment need not be made until the end of
                  the next payment interval even if that payment interval ends
                  in the next calendar year. Payment intervals are the periods
                  for which payments are received (for example, bi-monthly,
                  monthly, semi-annually, or annually). All of the Member's or
                  former Member's benefit accruals as of the last day of the
                  first Distribution Calendar Year will be included in the
                  calculation of the amount of the annuity payments for payment
                  intervals ending on or after the Member's or former Member's
                  Required Beginning Date.

                           Any additional benefits accruing to the Member or
                  former Member in a calendar year after the first Distribution
                  Calendar Year will be distributed beginning with the first
                  payment interval ending in the calendar year immediately
                  following the calendar year in which such amount accrues.

                           (c) Requirements For Annuity Distributions That
                  Commence During Member's Lifetime.

                                    (1) Joint Life Annuities Where the Section
                           401(a)(9) Beneficiary Is Not the Member's or former
                           Member's Spouse. If the Member's or the former
                           Member's interest

                           is being distributed in the form of a joint and
                           survivor annuity for the joint lives of the Member or
                           former Member and a nonspouse Section 401(a)(9)
                           Beneficiary, annuity payments to be made on or after
                           the Member's or former Member's Required Beginning
                           Date to the Section 401(a)(9) Beneficiary after the
                           Member's or former Member's death must not at any
                           time exceed the applicable percentage of the annuity
                           payment for such period that would have been payable
                           to the Member or former Member using the table set
                           forth in Q&A 2 of section 1.401(a)(9)-6T of the
                           Department of Treasury Regulations. If the form of
                           distribution combines a joint and survivor annuity
                           for the joint lives of the Member or the former
                           Member and a nonspouse Beneficiary and a period
                           certain annuity, the requirement in the preceding
                           sentence will apply to annuity payments to be made to
                           the Section 401(a)(9) Beneficiary after the
                           expiration of the period certain.

                                    (2) Period Certain Annuities. Unless the
                           Member's or former Member's Spouse is the sole
                           Section 401(a)(9) Beneficiary and the form of
                           distribution is a period certain and no life annuity,
                           the period certain for an annuity distribution
                           commencing during the Member's or former Member's
                           lifetime may not exceed the applicable distribution
                           period for the Member or former Member under the
                           Uniform Lifetime Table set forth in section

                           Annuity Starting Date. If the Annuity Starting Date
                           precedes the year in which the Member or former
                           Member reaches age 70, the Applicable Distribution
                           Period for the Member or former Member is the
                           distribution period for age 70 under the Uniform
                           Lifetime Table set forth in section 1.401(a)(9)-9 of
                           the Department of Treasury Regulations plus the
                           excess of 70 over the age of the Member or former

                           in the year that contains the Annuity Starting Date.
                           If the Member's or former Member's Spouse is the
                           Member's or former Member's sole Section 401(a)(9)
                           Beneficiary and the form of distribution is a period
                           certain and no life annuity, the period certain may
                           not exceed the longer of the Member's or the former
                           Member's applicable distribution period, as
                           determined hereunder, or the joint life and last
                           survivor expectancy of the Member or former Member

                           determined under the Joint and Last Survivor Table
                           set forth in section 1.401(a)(9)-9 of the Department
                           of Treasury Regulations, using the Member's or former
                           Member's and Spouse's attained ages as of the
                           Member's or former Member's and Spouse's birthdays in
                           the calendar year that contains the Annuity Starting

                           nonforfeitable interest will be distributed,
                           beginning no later than the time described in Section

                                    (4) If there is no Section 401(a)(9)
                           Beneficiary as of September 30 of the calendar year

                           surviving Spouse is the Member's or former Member's
                           sole Section 401(a)(9) Beneficiary and the surviving
                           Spouse dies after the Member or former Member but
                           before distributions to the surviving Spouse begin,
                           this Section 11.7(e), other than Section 11.7(e)(1),
                           will apply as if the surviving Spouse were the
                           Member.

                           For purposes of this Section 11.7(e) and Section
                  11.7(d), distributions are considered to begin on the Member's

                  11.7(e)(4) applies, the date distributions are required to
                  begin to the surviving Spouse under Section 11.7(e)(1)). If
                  annuity payments irrevocably commence to the Member or former
                  Member before the Member's or former Member's Required
                  Beginning Date (or to the Member's or former Member's
                  surviving Spouse before the date distributions are required to
                  begin to the surviving Spouse under Section 11.7(e)(1)), the

                  Former Member Dies On or After His Required Beginning Date. If
                  a Member or former Member dies on or after his Required
                  Beginning Date, his Plan benefit must be distributed to his
                  Section 401(a)(9) Beneficiary at least as rapidly as the
                  method of payment of minimum required distributions being used
                  as of the date of his death.

                           (g) Limitations on Death Benefits. Benefits payable
                  under the Plan shall not be provided in any form that would
                  cause a Member's death benefit to be more than incidental. Any
                  distribution required to satisfy the incidental benefit
                  requirement shall be considered a required distribution for
                  purposes of section 401(a)(9) of the Code.

                  former Member's nonforfeitable interest in his Plan benefit is
                  paid in the form of annuity distributions under the Plan,
                  payments under the annuity will satisfy the following
                  requirements:

                           than one year;

                                    (2) the distribution period will be over a
                           life (or lives) or over a period certain not longer
                           than the period described in Section 11.7(c) or
                           11.7(d);

                                    (3) once payments have begun over a period
                           certain, the period certain will not be changed even
                           if the period certain is shorter than the maximum
                           permitted;

                                    (4) payments will either be nonincreasing or

                  including, effective January 1, 2003, the Final Section
                  401(a)(9) Regulations, including sections 1.401(a)(9)-1
                  through 1.401(a)(9)-9 of the Final Section 401(a)(9)
                  Regulations. The provisions of the Plan reflecting section
                  401(a)(9) of the Code override any distribution options in the
                  Plan inconsistent with section 401(a)(9) of the Code."

6.       ARTICLE XIX.  Effective January 1, 2003, Article XIX of the Plan is
hereby amended by adding the following new Section 19.13:

                  "19.13 Arbitration. Any controversy arising out of or relating
         to the Plan, including without limitation, any and all disputes, claims
         (whether in tort, contract, statutory or otherwise) or disagreements
         concerning the interpretation or application of the provisions of the
         Plan, the Company's employment of the Member, or former Member, and the
         termination of that employment, shall be resolved by arbitration in
         accordance with the Employee Benefit Plan Claims Arbitration Rules of
         the American Arbitration Association (the "AAA") then in effect. No
         arbitration proceeding relating to the Plan may be initiated by either
         the Company or the Member, or former Member, unless the claims review
         and appeals procedures specified in Article XII have been exhausted.
         Within ten (10) business days of the initiation of an arbitration
         hereunder, the Company and the Member, or former Member, will each
         separately designate an arbitrator, and within twenty (20) business
         days of selection, the appointed arbitrators will appoint a neutral
         arbitrator from the panel of AAA National Panel of Employee Benefit
         Plan Claims Arbitrators. The arbitrators shall issue their written
         decision (including a statement of finding of facts) within thirty (30)
         days from the date of the close of the arbitration hearing. The
         decision of the arbitrators selected hereunder will be final and
         binding on both parties. This arbitration provision is expressly made
         pursuant to and shall be governed by the Federal Arbitration Act, 9
         U.S.C. Sections 1-16 (or replacement or successor statute). Pursuant to
         Section 9 of the Federal Arbitration Act, the Company and any Member
         agrees that any Member agrees that any judgment of the United States
         District Court for the District in which the headquarters of the
         Company is located at the time of initiation of an arbitration
         hereunder shall be entered upon the award made pursuant to the
         arbitration. Nothing in this Section 19.13 shall be construed to, in
         any

<PAGE>

         way, limit the scope and effect of Article XIII. In any arbitration
         proceeding full effect shall be given to the rights, powers, and
         authorities of the Plan Administrator under Article XIII."

7.       SECTION 20.3. The definition of "Testing Period" in Section 20.3 of the
Plan is amended by adding the following sentence immediately prior to the last
sentence: "Also, any Service shall be disregarded to the extent that such
Service occurs during a Plan Year when the Plan benefits (within the meaning of
section 410(b) of the Code) no Key Employee or former Key Employee."

8.       SECTION 20.7. The definition of "Key Employee" in Section 20.7 of the
Plan is amended to read in its entirety as follows:

                  "(d) "Key Employee" means an Employee or former Employee
         (including a deceased Employee) who at any time during the Plan Year is
         (1) an officer of any Affiliate having Compensation greater than
         $130,000.00 (as adjusted by the Secretary of Treasury from time to time
         for increases in the cost of living), (2) a Five Percent Owner of any
         Affiliate treated separately, or (3) a one percent owner of any
         Affiliate (within the meaning of Section 416(i) of the Code), treated
         separately, having Compensation greater than $150,000.00. For this
         purpose, no more than fifty (50) employees or, if lesser, the greater
         of three (3) employees or ten percent (10%) of the employees shall be
         treated as officers.

                  For purposes of determining the number of officers taken into
         account, the following employees shall be excluded: (1) employees who
         have not completed six (6) months of Service, (2) employees who
         normally work less than seventeen and one-half (17-1/2) hours per week,
         (3) employees who normally work not more than six (6) months during any
         year, (4) employees who have not attained the age of twenty-one (21),
         and (5) except to the extent provided in Department of Treasury
         Regulations, employees who are included in a unit of employees covered
         by an agreement which the Secretary of Labor finds to be a collective
         bargaining agreement between employee representatives and an Affiliate.
         Section 416(i) of the Code shall be used to determine percentage of
         ownership.

                  The determination of who is a Key Employee will be made in
         accordance with section 416(i) of the Code and applicable Department of
         Treasury Regulations."

9.       SECTION 20.7(f). Paragraph (f) of Section 20.7 is amended by
renumbering clauses (iii) and (iv) as clauses (v) and (vi); deleting the
existing clause (ii); and adding the following new clauses (ii), (iii) and (iv):

                  "(ii) In determining the present value of the accumulated
         accrued benefits for any Employee or the amount in the account of any
         Employee, the value or amount shall be increased by all distributions
         made to or for the benefit of the Employee under the Plan on account of
         his Separation From Service and during the one-year period ending on
         the Determination Date.

                  (iii) In determining the present value of the accumulated
         accrued benefits for any Employee or the amount in the account of any
         Employee, the value or amount shall be increased by all distributions
         made to or for the benefit of the Employee under the Plan other than on
         account of his Separation From Service and during the five-year period
         ending on the Determination Date.

                  (iv) Notwithstanding any other provision of the Plan, benefits
         shall not be taken into account in determining the top-heavy ratio for
         any Employee who has not performed services for an Affiliate during the
         last one-year period ending upon the Determination Date.

                  IN WITNESS WHEREOF, the Company has caused this Agreement to
         be executed on this 31st day of December, 2002.

3.    Administration.  The Plan shall be administered by the Committee, which shall have full power and authority to administer and interpret the Plan and to adopt such rules, regulations,

 

2 

agreements, guidelines and instruments for the administration of the Plan as the Committee deems necessary or advisable. The Committee’s
powers include, but are not limited to (subject to the specific limitations described herein), authority to determine the employees to be granted Options under the Plan, to determine the size and applicable terms and conditions of grants to be made
to such employees, to determine the time when Options will be granted and to authorize grants to eligible employees. 
 
The Committee’s interpretations of the Plan, and all actions taken and determinations made by the Committee concerning any matter
arising under or with respect to the Plan or any Options granted hereunder, shall be final, binding and conclusive on all interested parties, including PepsiCo, its shareholders and all former, present and future employees of the Company. The
Committee may delegate some or all of its power and authority hereunder to the Chairman and Chief Executive Officer of PepsiCo, such delegation to be subject to such terms and conditions as the Committee in its discretion shall determine. The
Committee may as to all questions of accounting rely conclusively upon any determinations made by the independent public accountants of PepsiCo, Inc. 
 
4.    Stock Available for Options.  The shares that may be delivered or purchased under the Plan
shall not exceed an aggregate number of shares of Common Stock to be determined from time to time by the Committee, subject to any adjustments which may be made pursuant to Section 11 hereof. Shares of Stock used for purposes of the Plan may be
either shares of authorized but unissued Common Stock or treasury shares or both. Stock covered by Options, which have terminated or expired prior to exercise or have been surrendered or canceled shall be available for further option hereunder.

 
5.    Eligibility.  All those employees of the Company who shall be determined from time to time by the Committee to be eligible, shall participate in the Plan; provided, however, any individual
who signs a written agreement pursuant to which he or she waives the right to participate in the Plan (either generally or with respect to certain grants of Options) shall not be eligible to participate in the Plan. The term “employee” as
used herein does not include any individual who is not, as of the Grant Date, classified by the Company as an employee on its corporate books and records even if that individual is later reclassified (by the Company, any court or any governmental or
regulatory agency) as an employee as of the Grant Date. No employee may be granted Options in the aggregate which, if exercised, would result in that employee receiving more than 10% of the maximum number of shares available for issuance under the
Plan. 
 
6.    Terms and
Conditions of Options.  Each Option granted hereunder shall be in writing and shall contain such terms and conditions as the Committee may determine, subject to the following: 
 
(a)  Option Exercise Price.  The
Option Exercise Price shall be equal to the Fair Market Value of a share of Common Stock on the Grant Date. 
 

3 

 
(b)  Term and Exercise Dates.  Options granted hereunder shall have a term of no longer than fifteen years from the Grant Date and shall become exercisable in accordance with the terms of their grant. A
grant of Options may become exercisable in installments, however, Stock Options must be exercised for full shares of Common Stock. To the extent that Stock Options are not exercised when they become initially exercisable, they shall be carried
forward and be exercisable until the expiration of the term of such Stock Options, subject to the provisions of Sections 6(e) and (f) hereof. 
 
(c)  Exercise of Option.  To exercise an Option, the holder thereof shall give notice of his or her exercise to
PepsiCo, or its agent, specifying the number of shares of Common Stock to be purchased and identifying the specific Options that are being exercised. From time to time the Committee or PepsiCo may establish procedures relating to effecting such
exercises. No fractional shares shall be issued as a result of exercising an Option. An Option is exercisable during an Optionee’s lifetime only by the Optionee; provided, however, that in the event the Optionee is incapacitated and unable to
exercise Options, such Options may be exercised by such Optionee’s legal guardian, legal representative, fiduciary or other representative whom the Committee deems appropriate based on applicable facts and circumstances. 
 
(d)  Payment of Option Exercise
Price.  The Option Exercise Price for the Options being exercised must be paid in full at time of issuance of the Common Stock. In addition, in order to enable the Company to meet any applicable foreign, federal (including FICA), state
and local withholding tax requirements, an Optionee shall also be required to pay the amount of tax to be withheld at the time of exercise. No share of Stock will be delivered to any Optionee until all such amounts have been paid. 
 
(e)  Effect of Termination of Employment,
Disability, Retirement, Death or Certain Transfer of Employment.  No Option may be exercised by an Optionee after the termination of his or her employment with the Company, except that: 
 
(i)  if such termination occurs by reason of the
Optionee’s death, all Options then held by the Optionee shall become immediately exercisable as of the date of death, shall remain exercisable until they expire in accordance with their terms and may be exercised by such Optionee’s
executor (or, if none, his or her legal representative) prior to the date such Options are transferred in accordance with Section 6(g) hereof, and after such date, by the applicable transferee of such Options; 
 
(ii)  if such termination occurs by reason of the
Optionee’s becoming Totally Disabled, all Options then held by the Optionee shall continue to become exercisable and shall be able to be exercised by the Optionee in accordance with their terms; 
 
(iii)  if such termination occurs by reason of the
Optionee’s Retirement, all Options then held by the Optionee shall become immediately exercisable as of the date of such Retirement and may be exercised by the Optionee until the expiration of such Options in accordance with their terms;

 

4 

 
(iv)  if such termination occurs by reason of the Optionee’s transfer to a Related Entity, and such transfer occurs as a result of actions by PepsiCo, all Options shall become immediately exercisable as of the date of
such transfer and shall otherwise remain outstanding and be exercisable in accordance with their terms; after the date of such transfer, a termination of employment from the Related Entity shall constitute a termination of employment under the Plan;
and 
 
(v)  subject to the foregoing
clauses (i) through (iv), if such termination is voluntary by the employee or is by action of the Company (except as described in Section 6(f) hereof), all Options then held by the Optionee which are exercisable at the date of termination shall
continue to be exercisable by the Optionee until the earlier of 90 calendar days after such date or the expiration of such Options in accordance with their terms. Unless the Committee shall determine otherwise, all Options which are not exercisable
at such date of termination shall automatically terminate and lapse 90 calendar days after such date of termination; provided, however, that such Options which are not exercisable on the date of termination shall in no event become exercisable
unless the registered owner is re-employed by the Company prior to the date on which such Options terminate and lapse. 
 
(f)  Misconduct.  In the event that an Optionee has (i) used for profit or disclosed to unauthorized persons,
confidential information or trade secrets of the Company, (ii) breached any contract with or violated any fiduciary obligation to the Company, (iii) engaged in unlawful trading in the securities of PepsiCo or of another company based on information
gained as a result of that Optionee’s employment with the Company, or (iv) committed a felony or other serious crime, then that Optionee shall forfeit all rights to any unexercised Options granted under the Plan and all of that
Optionee’s outstanding Options shall automatically terminate and lapse, unless the Committee shall determine otherwise. 
 
(g)  Nontransferability of Options.  During an Optionee’s lifetime, his or her Options shall not be
transferable and shall only be exercisable by the Optionee, and any purported transfer shall be null and void. No Option shall be transferable other than by will or the laws of descent and distribution. 
 
(h)  Effect of a Change in
Control.  Notwithstanding anything to the contrary in this Plan, at the date of a Change in Control, all outstanding and unvested Options granted under the Plan shall immediately vest and become exercisable, and all Options then
outstanding under the Plan shall remain outstanding in accordance with their terms. In the event that any Option granted under the Plan becomes unexercisable during its term on or after a Change in Control because: (i) the individual who holds such
Option is involuntarily terminated (other than for cause) within two (2) years after the Change in Control; (ii) such Option is terminated or adversely modified; or (iii) PepsiCo Common Stock is no longer issued and outstanding, or no longer traded
on a national securities exchange, then the holder of such Option shall immediately be entitled to receive a lump sum cash payment equal to the greater of (x) the gain on such Option or (y) the Black-Scholes value of such Option (as determined by a
nationally recognized independent investment banker chosen by PepsiCo), in either case calculated on the date such Option becomes unexercisable. For purposes of the preceding sentence, the gain on an Option shall be 
 

5 

calculated as the difference between the closing price per share of PepsiCo Common Stock as of the date such Option becomes unexercisable
less the Option Exercise Price of such Option. Any amount required to be paid pursuant to this Section 6(h) shall be paid within twenty (20) days after the date such amount becomes payable. 
 
7.    Amendment.  The
Committee (or the Chairman and Chief Executive Officer of PepsiCo, if a delegation of authority is in effect) may, at any time, amend, suspend or terminate the Plan, in whole or in part, provided that no such action shall adversely affect any rights
or obligations with respect to any grants theretofore made hereunder. The Committee may amend the terms and conditions of outstanding Options, provided, however, that (i) no such amendment shall be adverse to the holders of the Options, (ii) no such
amendment shall extend the period for exercise of an Option, and (iii) the amended terms of the Option would be permitted under this Plan. 
 
8.    Foreign Employees.  Without amending the Plan, the Committee may grant Options to eligible
employees who are foreign nationals on such terms and conditions different from those specified in this Plan as may in the judgment of the Committee be necessary or desirable to foster and promote achievement of the purposes of the Plan, and, in
furtherance of such purposes the Committee may make such modifications, amendments, procedures, subplans and the like as may be necessary or advisable to comply with provisions of laws in other countries in which the Company operates or has
employees. 
 
9.    Registration, Listing and Qualification of Shares.  Each Option shall be subject to the requirement that if at any time the Committee shall determine that the registration, listing or
qualification of the shares covered thereby upon any securities exchange or under any foreign, federal, state or local law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of, or in connection
with, the granting of such Option or the purchase of shares thereunder, no such Option may be exercised unless and until such registration, listing, qualification, consent or approval shall have been effected or obtained free of any condition not
acceptable to the Committee. Any person exercising an Option shall make such representations and agreements and furnish such information as the Committee may request to assure compliance with the foregoing or any other applicable legal requirements.

 
10.    Buy Out of Option
Gains.  At any time after any Stock Option becomes exercisable, the Committee shall have the right to elect, in its sole discretion and without the consent of the holder thereof, to cancel such Option and to cause PepsiCo to pay to the
Optionee the excess of the Fair Market Value of the shares of Common Stock covered by such Option over the Option Exercise Price of such Option at the date the Committee provides written notice (the “Buy Out Notice”) of its intention to
exercise such right. Buy outs pursuant to this provision shall be effected by PepsiCo as promptly as possible after the date of the Buy Out Notice. Payments of buy out amounts may be made in cash, in shares of Common Stock, or partly in cash and
partly in Common Stock, as the Committee deems advisable. To the extent payment is made in shares of Common Stock, the number of shares shall be determined by dividing the amount of the payment to be made by the Fair Market Value of a share of
Common Stock at the date of the Buy Out Notice. In no event shall PepsiCo be required to deliver a fractional share of Common Stock 
 

6 

in satisfaction of this buy out provision. Payments of any such buy out amounts shall be made net of any applicable foreign, federal
(including FICA), state and local withholding taxes. 
 
11.    Adjustment for Change in Stock Subject to Plan.  In the event of any change in the outstanding shares of Common Stock by reason of any stock split, stock dividend, recapitalization,
spin-off, merger, consolidation, combination or exchange of shares or other similar corporate change, such equitable adjustments may be made in the Plan and the Options granted hereunder as the Committee determines are necessary or appropriate,
including, if necessary, an adjustment in the number of shares and Option Exercise Prices per share applicable to Options then outstanding and in the number of shares which are reserved for issuance under the Plan. Any such adjustment shall be
conclusive and binding for all purposes of the Plan. 
 
12.    No Rights to Options or Employment.  No employee or other person shall have any claim or right to be granted an Option under the Plan. Having received an Option under the Plan shall not
give an employee any right to receive any other grant under the Plan. An Optionee shall have no rights to or interest in any Option except as set forth herein. Neither the Plan nor any action taken hereunder shall be construed as giving any employee
any right to be retained in the employ of the Company. 
 
13.    Rights as Shareholder.  An Optionee under the Plan shall have no rights as a holder of Common Stock with respect to Options granted hereunder, unless and until certificates for shares of
Common Stock are issued to such Optionee. 
 
14.    Other Actions.  This Plan shall not restrict the authority of the Committee or of PepsiCo, for proper corporate purposes, to grant or assume stock options, other than under the Plan, to or
with respect to any employee or other person. 
 
15.    Costs and Expenses.  Except as provided in Sections 6 and 10 hereof with respect to taxes and except for certain other fees and commissions related to the exercise of options, the costs and
expenses of administering the Plan shall be borne by PepsiCo and shall not be charged to any grant nor to any employee receiving a grant. 
 
16.    Plan Unfunded.  The Plan shall be unfunded. Except for reserving a sufficient number of
authorized shares to the extent required by law to meet the requirements of the Plan, PepsiCo shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the delivery of PepsiCo Common Stock
upon exercise of any Option granted under the Plan. 
 
17.    Governing Law.  This Plan shall be governed by and construed in accordance with the laws of the State of North Carolina. 
 
18.    Effectiveness and Duration of the Plan.  This Plan was initially
effective on July 1, 1989 and was last amended and restated effective as of August 3, 2001. No Option shall be granted hereunder after December 31, 2008.
