                        TEXAS PETROCHEMICALS CORPORATION
                          EMPLOYEE STOCK OWNERSHIP PLAN

                              W I T N E S S E T H:

      WHEREAS, TPC Finance Corp. (the "Employer") desires to establish an
Employee Stock Ownership Plan so as to enable its eligible employees to acquire
a proprietary interest in capital stock of the Employer; and

      WHEREAS, the Employer desires to recognize the contributions employees
will make to its successful operation and to reward such contribution by means
of an Employee Stock Ownership Plan for those employees who shall qualify as
Participants hereunder; and

      WHEREAS, contributions to the Plan will be made by the Employer and such
contributions made to the trust will be invested primarily in the capital stock
of the Employer (or a corporation which is a member of the same controlled
group); and

      WHEREAS, effective July 1, 1996 (hereinafter called the "Effective Date"),
the Employer establishes this Employee Stock Ownership Plan ("ESOP") (which plan
is hereinafter called the "Plan") for the exclusive benefit of the Participants
and their Beneficiaries, which is intended to qualify as an ESOP; and

      WHEREAS, it is anticipated that soon after the Effective Date, TPC Holding
Corp. will purchase all outstanding capital stock of Texas Olefins Company and
its subsidiaries, including Texas Petrochemicals Corporation (the
"Acquisition"), and that concurrently with the consummation of the closing of
the Acquisition, the Employer and Texas Olefins Company will merge with Texas
Petrochemicals Corporation (the "Merger") and the surviving entity will be named
Texas Petrochemicals Corporation; and

      WHEREAS, upon the completion of the Merger, the Plan shall be renamed the
Texas Petrochemicals Corporation Employee Stock Ownership Plan.

      NOW THEREFORE, as of the Effective Date, the Employer hereby establishes
this ESOP for the exclusive benefit of its participants and their beneficiaries
under the following terms:

                                       -1-

      1.5   "ANNIVERSARY DATE" means June 30.

      1.6 "BENEFICIARY" means the person to whom the share of a deceased
Participant's total account is payable, subject to the restrictions of Sections
7.2 and 7.6.

      1.7 "BENEFIT COMMENCEMENT DATE" means with respect to each Participant or
Beneficiary, the date such Participant's or Beneficiary's benefit is paid to him
from the Trust Fund.

      1.8 "CODE" means the Internal Revenue Code of 1986, as amended or replaced
from time to time.

      1.9 "COMPANY STOCK" means common stock issued by the Employer (or by a
corporation which is a member of the controlled group of corporations of which
the Employer is a member) which is readily tradeable on an established
securities market. If there is no common stock which meets the foregoing
requirement, the term "Common Stock" means common stock issued by the Employer
(or by a corporation which is a member of the same controlled group) having a
combination of voting power and dividend rights equal to or in excess of: (A)

(or of any other such corporation) having the greatest dividend rights.
Preferred Stock shall be deemed to be "Company Stock" if such stock is

and if such conversion is at a conversion price which (as of the date of the
acquisition by the Trust) is reasonable.

                                       -2-

      1.10 "COMPANY STOCK ACCOUNT" means the account of a Participant which is

      1.11 "COMPENSATION" with respect to any Participant means such

Compensation with respect to any Participant shall include Compensation for the
entire twelve month period ending on the last day of such Plan Year, except that
Compensation shall be recognized only for that portion of the Plan Year during
which an Employee was a Participant in the Plan. Amounts contributed pursuant to
a salary reduction agreement that are not includable in the gross income of the
Participant under Code Sections 125, 402(e)(3), 402(h), 403(b) or 457, and

the "OBRA '93 Annual Compensation Limit." The "OBRA '93 Annual Compensation
Limit" is $150,000, as adjusted for increases in the cost of living in
accordance with Code Section 401(a)(17)(B). The cost of living adjustment in
effect for a calendar year applies to any period, not exceeding 12 months, over
which Compensation is determined ("Determination Period") beginning in such
calendar year. If a Determination Period consists of fewer than 12 months, the
"OBRA '93 Annual Compensation Limit" will be multiplied by a fraction, the
numerator of which is the number of months in the Determination Period, and the
denominator of which is 12.

      Any reference in this Plan to the limitation under Code Section 401(a)(17)
shall mean the "OBRA '93 Annual Compensation Limit" set forth in this Section.

      If Compensation for any prior Determination Period is taken into account
in determining a Participant's benefits accruing in the current Plan Year, the
Compensation for that prior Determination Period is subject to the "OBRA '93
Annual Compensation Limit" in effect for that prior Determination Period. For
this purpose, for Determination Periods beginning before the first day of the
first Plan Year beginning on or after January 1, 1994, the "OBRA '93 Annual
Compensation Limit" is $150,000.

      For a Participant's initial year of participation, Compensation shall be
recognized for the entire Plan Year.

      1.12 "CURRENT OBLIGATIONS" means Trust obligations arising from extension
of credit to the Trust and payable in cash within (1) year from the date an
Employer contribution is due. Trust obligations shall include the liability for
payment of taxes imposed by Code Section 2001 which liability is incurred
pursuant to Code Section 2210(b).

                                       -3-

the subject of good faith bargaining between the parties, unless such agreement
expressly provides for such coverage in this Plan, will not be eligible to
participate in this Plan.

or a loan to the Plan which is guaranteed by a disqualified person and which
satisfies the requirements of Section 2550.408b-3 of the Department of Labor
Regulations, Section 54.4975-7(b) of the Treasury regulations and Section 5.4
hereof.

414(q)(6)(B).

      1.24 "FORMER PARTICIPANT" means a person who has been a Participant, but
who has ceased to be a Participant for any reason. For purposes of Section 1.28,
a "Former Participant" shall be treated as a Highly Compensated Participant if
such "Former Participant" was a Highly Compensated Participant when he separated
from service with the Employer or was a Highly Compensated Participant at any
time after attaining age 55.

      1.25  "415 COMPENSATION" means compensation as defined in Section 4.4(e).

      1.26 "HIGHLY COMPENSATED EMPLOYEE" means any Employee or former Employee
who is a highly compensated employee as defined in Code Section 414(q) and the
Regulations thereunder. Generally, any Employee or former Employee is considered
a Highly Compensated Employee if such Employee or former Employee performed
services for the Employer during the "determination year" and is one or more of
the following groups:

            (a) Employees who at any time during the "determination year" or
      "look-back year" were "five percent owners" as defined in Section 1.30(c).

            (b) Employees who received "415 Compensation" during the "look-back
      year" from the Employer in excess of $75,000. In determining whether an
      individual has "415 Compensation" of more than $75,000, "415 Compensation"
      from each employer required to be aggregated under Code Sections 414(b),
      (c), (m) and (o) shall be taken into account.

            (c) Employees who received "415 Compensation" during the "look-back
      year" from the Employer in excess of $50,000 and were in the top-paid
      group of Employees for the Plan Year. An Employee is in the top-paid group
      of Employees for any Plan Year if such Employee is in the group consisting
      of the top twenty (20%) percent of the Employees when ranked on the basis
      of "415 Compensation" paid during the Plan Year. In determining whether an
      individual has "415 Compensation" of more than $50,000, "415 Compensation"
      from each employer required to be aggregated under Code Section 414(b),
      (c), (m) and (o) shall be taken into account.

            (d) Employees who during the "look-back year" were officers as
      defined in Section 1.30(a) and received "415 Compensation" during the
      "look-back year" from the Employer greater than 50 percent of the limit in
      effect under Code Section 415(b)(1)(A) for any such Plan Year. The number
      of officers shall be limited to the lesser of (i) 50 employees; or (ii)
      the greater of 3 employees or 10 percent of all employees. For the purpose
      of determining the number of officers, the following Employees shall be
      excluded:

                    (1)  Employees with less than six (6) months of service;

                    (2)  Employees who normally work less than 17 1/2 hours per
                         week;

                    (3)  Employees who normally work less than six (6) months
                         during a year; and

                                       -5-

                    (4)  Employees who have not yet attained age 21.

            However, such Employees shall still be considered for the purpose of
      identifying the particular Employees who are officers. If the Employer
      does not have at least one officer whose annual "415 Compensation" is in
      excess of 50 percent of the Code Section 415(b)(1)(A) limit, then the
      highest paid officer of the Employer will be treated as a Highly
      Compensated Employee.

            (e) Employees who are in the group consisting of the 100 Employees
      paid the greatest "415 Compensation" during the "determination year" and
      are also described in (b), (c) or (d) above when these paragraphs are
      modified to substitute "determination year" for "look-back year."

      The "look-back year" shall be the calendar year ending with or within the
Plan Year for which testing is being performed, and the "determination year" (if
applicable) shall be the period of time, if any, that extends beyond the
"look-back year" and ends on the last day of the Plan Year for which testing is
being performed (the "lag period"). If the "lag period" is less than twelve
months long, the threshold amounts specified in (b), (c), and (d) above shall be
prorated based upon the number of months in the "lag period."

      For purposes of this Section, the determination of "415 Compensation"
shall be based only on "415 Compensation" which is actually paid and shall be
made by including amounts which are contributed by the Employer pursuant to a
salary reduction agreement and which are not includible in the gross income of
the Participant under Code Sections 125, 402(e)(3), 402(h), 403(b) or 457, and
Employee contributions described in Code Section 414(h)(2) that are treated as
Employer contributions. Additionally, the dollar threshold amounts specified in
(b) and (c) above shall be adjusted at such time and in such manner as is
provided in Regulations. In the case of such an adjustment, the dollar limits
which shall be applied are those for the calendar year in which the
"determination year" or "look-back year" begins.

      In determining who is a Highly Compensated Employee, Employees who are
non-resident aliens and who received no earned income (within the meaning of
Code Section 911(d)(2)) from the Employer constituting United States source
income within the meaning of Code Section 861(a)(3) shall not be treated as
Employees. Additionally, all Affiliated Employers shall be taken into account as
a single employer and Leased Employees within the meaning of Code Sections
414(n)(2) and 414(o)(2) shall be considered Employees unless such Leased
Employees are covered by a plan described in Code Section 414(n)(5) and are not
covered in any qualified plan maintained by the Employer. The exclusion of
Leased Employees for this purpose shall be applied on a uniform and consistent
basis for all of the Employer's retirement plans

      1.27 "HIGHLY COMPENSATED PARTICIPANT" means any Highly Compensated
Employee who is eligible to participate in the Plan.

      1.28 "HOUR OF SERVICE" means (1) each hour for which an Employee is
directly or indirectly compensated or entitled to compensation by the Employer
for the performance of duties during the

                                       -6-

applicable computation period; (2) each hour for which an Employee is directly
or indirectly compensated or entitled to compensation by the Employer
(irrespective of whether the employment relationship has terminated) for reasons
other than performance of duties (such as vacation, holidays, sickness, jury
duty, disability, lay-off, military duty, or leave of absence) during the
applicable computation period; and (3) each hour for which back pay is awarded
or agreed to by the Employer without regard to mitigation of damages.

      Notwithstanding the above, (i) no more than 501 Hours of Service are
required to be credited to an Employee on account of any single continuous
period during which the Employee performs no duties (whether or not such period
occurs in a single computation period); (ii) an hour for which an Employee is
directly or indirectly paid, or entitled to payment, on account of a period
during which no duties are performed is not required to be credited to the
Employee if such payment is made or due under a plan maintained solely for the
purpose of complying with applicable worker's compensation, or unemployment
compensation or disability insurance laws; and (iii) Hours of Service are not
required to be credited for a payment which solely reimburses an Employee for
medical or medically related expenses incurred by the Employee.

      For purposes of this Section, a payment shall be deemed to be made by or
due from the Employer regardless of whether such payment is made by or due from
the Employer directly, or indirectly through, among others, a trust fund, or
insurer, to which the Employer contributes or pays premiums and regardless of
whether contributions made or due to the trust fund, insurer, or other entity
are for the benefit of particular Employees or are on behalf of a group of
Employees in the aggregate.

      An Hour of Service must be counted for the purpose of determining a Year
of Service, a year of participation for purposes of accrued benefits, a 1-Year
Break in Service, and employment commencement date (or reemployment commencement
date). The provisions of Department of Labor regulations 2530.200b-2(b) and (c)

      1.30 "KEY EMPLOYEE" means an Employee as defined in Code Section 416(i)

time during the Plan Year or any of the preceding four (4) Plan Years, has been
included in one of the following categories:

            (a) an officer of the Employer (as that term is defined within the
      meaning of the Regulations under Code Section 416) having annual "415
      Compensation" greater than 50 percent of the amount in effect under Code
      Section 415(b)(1)(A) for any such Plan Year;

            (b) one of the ten Employees having annual "415 Compensation" from
      the Employer for a Plan Year greater than the dollar limitation in effect
      under Code Section

                                       -7-

      415(c)(1)(A) for the calendar year in which such Plan Year ends and owning
      (or considered as owning within the meaning of Code Section 318) both more

      of an unincorporated business, any person who owns more than five percent
      (5%) of the capital or profits interest in the Employer. In determining
      percentage ownership here under, Employers that would otherwise be
      aggregated under Code Sections 414(b), (c), (m) and (o) shall be treated
      as separate employers; or

            (d) a "one percent owner" of the Employer having an annual "415
      Compensation" from the Employer of more than $150,000. "One percent owner"

      of Code Section 318) more than one percent (1%) of the outstanding stock
      of the Employer or stock possessing more than one percent (1%) of the
      total combined voting power of all stock of the Employer, or, in the case
      of an unincorporated business, any person who owns more than one percent
      (1%) of the capital or profits interest in the Employer. In determining
      percentage ownership hereunder, Employers that would otherwise be
      aggregated under Code Sections 414(b), (c), (m) and (o) shall be treated
      as separate Employers. However, in determining whether an individual has
      "415 Compensation" of more than $150,000, "415 Compensation" from each
      employer required to be aggregated under Code Sections 414(b), (c), (m)
      and (o) shall be taken into account.

      For purposes of this Section, the determination of "415 Compensation"
shall be based only on "415 Compensation" which is actually paid and shall be
made by including amounts which are contributed by the Employer pursuant to a
salary reduction agreement and which are not includible in the gross income of
the Participant under Code Sections 125, 402(e)(3), 402(h), 403(b) or 457, and

Service shall be credited for the computation period in which the absence from
work begins, only if credit therefore is necessary to prevent the Employees from
incurring a 1-Year Break in Service, or, in any other case, in the immediately
following computation period.

      If more than one person is appointed as Administrator, the Employer may
designate the responsibilities of each Administrator as may be specified by the
Employer and accepted in writing by each Administrator. In the event that no

responsibilities among themselves, in which event the Administrators shall

of the Plan. Any such determination by the Administrator shall be conclusive and
binding upon all persons. The Administrator may establish procedures, correct
any defect, supply any information, or reconcile any inconsistency in such
manner and to such extent as shall be deemed necessary or advisable to carry out
the purpose of the Plan; provided, however, that any procedure, discretionary
act, interpretation or construction shall be done in a nondiscriminatory manner
based upon uniform principles consistently applied and shall be consistent with
the intent that the Plan shall continue to be deemed a qualified plan under the
terms of Code Section 401(a), and shall comply with the terms of the Act and all
regulations issued pursuant thereto. The Administrator shall have all powers
necessary or appropriate to accomplish his duties under this Plan.

      consult with the Employer, and it shall determine whether the Plan has a
      short range need for liquidity (e.g., to pay benefits) or whether
      liquidity is a long range goal and investment growth (and stability of
      same) is a more current need, or shall appoint a qualified person to do
      so. Such "funding policy and method" shall be consistent with the
      objectives of this Plan and with the requirements of Title I of the Act;

                                      -13-

      are required by Section 103 of the Act or the Secretary of Labor to be

            involving an amount in excess of five percent (5%) of Plan assets.

            All auditing and accounting fees shall be an expense of and may, at
      the election of the Administrator, be paid from the Trust Fund.

vest in his interest in the Plan for each Year of Service completed while a
noneligible Employee, until such time as his Participant's Account shall be
forfeited or distributed pursuant to the terms of the Plan. Additionally, his
interest in the Plan shall continue to share in the earnings of the Trust Fund.

      3.5   OMISSION OF ELIGIBLE EMPLOYEE

      If, in any Fiscal Year, any Employee who should be included as a
Participant in the Plan is erroneously omitted and discovery of such omission is
not made until after a contribution by his Employer for the year has been made,
the Employer shall make a subsequent contribution with respect to the omitted
Employee in the amount which the Employer would have contributed with respect to
him had he not been omitted. Such contribution shall be made regardless of
whether or not it is deductible in whole or in part in any taxable year under
applicable provisions of the Code.

                                      -17-

      3.6   INCLUSION OF INELIGIBLE EMPLOYEE

      If, in any Fiscal Year, any person who should not have been included as a
Participant in the Plan is erroneously included and discovery of such incorrect
inclusion is not made until after a contribution for the year has been made, the
Employer shall not be entitled to recover the contribution made with respect to
the ineligible person regardless of whether or not a deduction is allowable with
respect to such contribution. In such event, the amount contributed with respect
to the ineligible person shall constitute a Forfeiture for the Fiscal Year in
which the discovery is made.

                                      -18-

                                   ARTICLE IV
                           CONTRIBUTION AND ALLOCATION

      4.1   EMPLOYER'S CONTRIBUTION

            (a) For each Plan Year, the Employer shall contribute to the Plan an
      amount as may be determined by its Board of Directors or its delegatees.

            (b) The Employer Contribution for any Plan Year shall not exceed the
      maximum amount allowable as a deduction to the Employer under the
      provisions of Code Section 404.

            (c) However, to the extent necessary to provide the top heavy
      minimum allocations, the Employer shall make a contribution even if it
      exceeds the amount which is deductible under Code Section 404.

      4.2   TIME OF PAYMENT OF EMPLOYER'S CONTRIBUTION

      Employer Contributions will be paid in cash, Company Stock or other
property as the Employer's Board of Directors or its delegatees may from time to
time determine. Company Stock and other property will be valued at their then
fair market value. The Employer Contribution will be paid to the Plan on or
before the date required to make such contribution a deduction on the Employer's
federal income tax return for the year.

      Notwithstanding the above, to the extent that the Plan has Current
Obligations, the Employer Contribution will be paid to the Plan in cash.

      4.3   ALLOCATION OF CONTRIBUTION, FORFEITURES AND EARNINGS

            (a) The Administrator shall establish and maintain an account in the
      name of each Participant to which the Administrator shall credit as of
      each Anniversary Date all amounts allocated to each such Participant as
      set forth herein. However, the Administrator may separately account for
      that portion of each Participant's Account attributable to Top Heavy Plan
      Years.

            (b) The Employer shall provide the Administrator with all
      information required by the Administrator to make a proper allocation of
      the Employer Contribution for each Plan Year. Within 45 days after the
      date of receipt by the Administrator for such information, the
      Administrator shall, with respect to the Employer Contribution pursuant to
      4.1(a), allocate such Contribution to each Participant's Account in the
      same proportion that each such Participant's Compensation for the year
      bears to the total Compensation of all Participants for such year.

            A Participant who is not an Employee on the last day of the Plan
      Year shall not share in the Employer Contribution for that year, unless
      required pursuant to Section 4.3(i) or

                                      -19-

      4.3(n). A Participant who performs less than a Year of Service shall not
      share in the Employer Contribution for that year, unless required pursuant
      to Section 4.3(i) or 4.3(n).

            (c) The Company Stock Account of each Participant shall be credited
      as of each Anniversary Date with Forfeitures of Company Stock and his
      allocable share of Company Stock (including fractional shares) purchased
      and paid for by the Plan or contributed in kind by the Employer. Stock
      dividends on Company Stock held in his Company Stock Account shall be
      credited to his Company Stock Account when paid. Cash dividends on Company
      Stock held in his Company Stock Account shall be used to repay an Exempt
      Loan, so long as one exists and may then, in the sole discretion of the
      Administrator, be credited to his Participants Other Investments Account.

            Company Stock acquired by the Plan with the proceeds of an Exempt
      Loan shall only be allocated to each Participant's Company Stock Account
      upon release from the Unallocated Company Stock Suspense Account as
      provided in Section 4.3(g) herein. Company Stock acquired with the
      proceeds of an Exempt Loan shall be an asset of the Trust Fund and
      maintained in the Unallocated Company Stock Suspense Account.

            Company Stock received by the Trust during a Plan Year with respect
      to a contribution by the Employer for the preceding Plan Year shall be
      allocated to the accounts of Participants as of the Anniversary Date at
      the end of such preceding Plan Year.

            (d) As of each Anniversary Date or as of the Valuation Date, before
      allocation of Employer Contributions and Forfeitures, any earnings or
      losses (net appreciation or net depreciation) of the Trust Fund shall be
      allocated in the same proportion that each Participant's and Former
      Participant's Other Investment Accounts (other than each Participant's
      Company Stock Account) bear to the total of all Participants' and Former
      Participants' Other Investment Accounts (other than participants' Company
      Stock Accounts) as of such date. Cash dividends on Company Stock allocated
      to each Participant's or Former Participant's Other Investment Accounts
      after the first month of the Plan Year shall not share in any earnings or
      losses of the Trust Fund for such year. Earnings or losses include the
      increase (or decrease) in the fair market value of assets of the Trust
      Fund (other than Company Stock in the participants' Company Stock
      Accounts) since the preceding Anniversary Date.

            Earnings or losses do not include the interest paid under any
      installment contract for the purchase of Company Stock by the Trust Fund
      or on any loan used by the Trust Fund to purchase Company Stock, nor does
      it include income received by the Trust Fund with respect to Company Stock
      acquired with the proceeds of an Exempt Loan to the extent such income is
      used to repay the loan; all income received by the Trust Fund from Company
      Stock acquired with the proceeds of an Exempt Loan shall be used to repay
      such loan.

            (e) The Administrator shall establish accounting procedures for the
      purpose of making the allocations, valuations and adjustments to
      Participants' Accounts provided for in this Section. Should the
      Administrator determine that the strict application of its

                                      -20-

      accounting procedures shall not result in an equitable and
      nondiscriminatory allocation among the Participants' Accounts, it may
      modify its procedures for the purpose of achieving an equitable and
      nondiscriminatory allocation in accordance with the general concepts of
      the Plan and the provisions of this Section, provided, however, that such
      adjustments to achieve equity shall not reduce the Vested portion of a
      Participant's Account.

            (f) Separate accounts shall be maintained for all inactive
      Participants who have a Vested interest in the Plan. Such separate
      accounts shall not require a segregation of the Plan assets and no
      Participant shall acquire any right to or interest in any specific asset
      of the Trust as a result of the allocations provided for in the Plan. All
      allocations shall be made as of the Anniversary Date referred to in this
      Section.

            (g) All Company Stock acquired by the Plan with the proceeds of an
      Exempt Loan must be added to and maintained in the Unallocated Company
      Stock Suspense Account. Such Company Stock shall be released and withdrawn
      from that account as if all Company Stock in that account were encumbered.
      For each Plan Year during the duration of the loan, the number of shares
      of Company Stock released shall equal the number of encumbered shares held
      immediately before release for the current Plan Year multiplied by a
      fraction, the numerator of which is the amount of principal paid for the
      Plan Year and the denominator of which is the sum of the numerator plus
      the principal to be paid for all future Plan Years. As of each Anniversary
      Date, the Plan must consistently allocate to each Participant's Account
      pursuant to Section 4.3(b), non-monetary units (shares and fractional
      shares of Company Stock) representing each Participant's interest in
      assets withdrawn from the Unallocated Company Stock Suspense Account.
      Income earned with respect to Company Stock in the Unallocated Company
      Stock Suspense Account shall be used to repay the Exempt Loan or used to
      purchase such Company Stock. Any income which is not so used must be
      allocated as income of the Plan.

            (h) As of each Anniversary Date any amounts which became Forfeitures
      since the last Anniversary Date shall first be made available to reinstate
      previously forfeited account balances of Former Participants, if any. The
      remaining Forfeitures, if any, shall be allocated among the Participants'
      Accounts in the same proportion that each such Participant's Compensation
      for the year bears to the total Compensation of all Participants for the
      year. In the event the allocation of Forfeitures provided herein shall
      cause the "annual addition" (as defined in Section 4.4) to any
      Participant's Account to exceed the amount allowable by the Code, the
      excess shall be reallocated in accordance with Section 4.5. However, a
      Participant who performs less than a Year of Service during any Plan Year
      or who does not perform an Hour of Service on the last day of any Plan
      Year shall not share in the Plan Forfeitures for that year, unless
      required pursuant to Section 4.3(i).

            (i) Minimum Allocations Required for Top Heavy Plan Years:
      Notwithstanding the foregoing, for any Top Heavy Plan Year, the sum of the
      Employer Contributions and Forfeitures allocated to the Participant's
      Account for each Non-Key Employee shall be equal to at least three percent
      (3%) of such Non-Key Employee's "415 Compensation" (reduced by
      contributions and forfeitures, if any, allocated to each Non-Key Employee
      in any defined

                                      -21-

      contribution plan included with this plan in a Required Aggregation
      Group). However, if (i) the sum of the Employer Contributions and
      Forfeitures allocated to the Participant's Account of each Key Employee
      for such Top Heavy Plan Year is less than three percent (3%) of each Key
      Employee's "415 Compensation" and (ii) this Plan is not required to be
      included in an Aggregation Group to enable a defined benefit plan to meet
      the requirements of Code Section 401(a)(4) of 410, the sum of the Employer
      Contributions and Forfeitures allocated to the Participant's Account of
      each Non-Key Employee shall be equal to the largest percentage allocated
      to the Participant's Account of any Key Employee.

            Except, however, no such minimum allocation shall be required in
      this Plan for any Non-Key Employee who participates in another defined
      contribution plan subject to Code Section 412 providing such benefits
      included with this Plan in a Required Aggregation Group.

            (j) For purposes of the minimum allocations set forth above the
      percentage allocated to the Participant's Account of any Key Employee
      shall be equal to the ratio of the sum of the Employer Contributions and
      Forfeitures allocated on behalf of such Key Employee divided by the "415
      Compensation" for such Key Employee.

            (k) For any Top Heavy Plan Year, the minimum allocations set forth
      above shall be allocated to the Participant's Account of all Non-Key
      Employees who are Participants and who are employed by the Employer on the
      last day of the Plan Year, including Non-Key Employees who have (1) failed
      to complete a Year of Service; (2) declined to make mandatory
      contributions (if required) or elective deferrals to the Plan; and (3)
      been excluded from participation because of their level of Compensation.

            (l) In lieu of the above, in any Plan Year in which a Non-Key
      Employee is a Participant in both this Plan and a defined benefit pension
      plan included in a Required Aggregation Group which is top heavy, the
      Employer shall not be required to provide such Non-Key Employee with both
      the full separate defined benefit plan minimum benefit and the full
      separate defined contribution plan minimum allocation.

            Therefore, for any Plan Year when the Plan is a Top Heavy Plan,
      Non-Key Employees who are participating in this Plan and a defined benefit
      plan maintained by the Employer shall receive a minimum monthly accrued
      benefit in the defined benefit plan equal to the product of (1)
      one-twelfth (1/12th) of "415 Compensation" averaged over a five (5)
      consecutive "limitation years" (or actual "limitation years" if less)
      which produce the highest average and (2) the lesser of (i) two percent
      (2%) multiplied by Years of Service when the plan is top heavy or (ii)
      twenty percent (20%).

            (m) For the purposes of this Section, "415 Compensation" shall be as
      defined in Section 4.4(e), and shall be limited to $150,000 in all Plan
      Years (unless adjusted in such manner as permitted under Code Section
      401(a)(17).

                                      -22-

            (n) Notwithstanding anything herein to the contrary, Participants
      terminating for reasons of death, Total and Permanent Disability or
      retirement shall share in the allocations of contributions and Forfeitures
      provided for in this Section regardless of whether they completed a Year
      of Service during the Plan Year.

            (o) If a Former Participant is reemployed after five (5) consecutive
      1-Year Breaks in Service, then separate accounts shall be maintained as
      follows:

                  (1)   one account for nonforfeitable benefits attributable to
            pre-break
            service; and

                  (2)   one account representing his status in the Plan 
            attributable to post-
            break service.

      4.4   MAXIMUM ANNUAL ADDITIONS

            (a) Notwithstanding the foregoing, the maximum "annual additions"
      credited to a Participant's accounts for any "limitation year" shall equal
      the lesser of: (1) $30,000 (or, if greater, one-fourth of the dollar
      limitation in effect under Code Section 415(b)(1)(A)) or (2) twenty-five
      percent (25%) of the Participant's "415 Compensation" for such "limitation
      year".

            (b) For purposes of applying the limitations of Code Section 415,
      "annual additions" means the sum credited to a Participant's accounts for
      any "limitation year" of (1) Employer Contributions, (2) Employee
      contributions, (3) Forfeitures, (4) amounts allocated, after March 31,
      1984, to an individual medical account, as defined in Code Section
      415(l)(2) which is part of a pension or annuity plan maintained by the
      Employer and (5) amounts derived from contributions paid or accrued after
      December 31, 1985, in taxable years ending after such date, which are
      attributable to post-retirement medical benefits allocated to the separate
      account of a key employee (as defined in Code Section 419A(d)(3)) under a
      welfare benefit plan (as defined in Code Section 419(e)) maintained by the
      Employer. Except, however, the "415 Compensation" percentage limitation
      referred to in paragraph (a)(2) above shall not apply to: (1) any
      contribution for medical benefits (within the meaning of Code Section
      419A(f)(2)) after separation from service which is otherwise treated as an
      "annual addition", or (2) any amount otherwise treated as an "annual
      addition" under Code Section 415(l)(1).

            (c) For purposes of applying the limitations of Code Section 415,
      the transfer of funds from one qualified plan to another is not an "annual
      addition." In addition, the following are not Employee contributions for
      the purposes of Section 4.4(b)(2): (1) rollover contributions (as defined
      in Code Sections 402(a)(5), 403(a)(4), 403(b)(8) and 408(d)(3)); (2)
      repayments of loans made to a Participant from the Plan; (3) repayments of
      distributions received by an Employee pursuant to Code Section
      411(a)(7)(B) (cash-outs); (4) repayments of distributions received by an
      Employee pursuant to Code Section 411(a)(3)(D) (mandatory

                                      -23-

      contributions); and (5) Employee contributions to a simplified employee
      pension excludable from gross income under Code Section 408(k)(6).

            (d) If no more than one-third of the Employer Contributions to this
      Plan for a Plan Year which are deductible under Code Section 404(a)(9) are
      allocated to Highly Compensated Employees, the limitations of paragraph
      (a) shall not apply to:

                  (1)   Forfeitures of Company Stock which were acquired with
            the proceeds of an Exempt Loan, or

                  (2) Employer Contributions to this Plan which are deductible
            under Code Section 404(a)(9)(B) and charged against the
            Participant's accounts.

            (e) For purposes of applying the limitations of Code Section 415,
      "415 Compensation" shall include the Participant's wages, salaries, fees
      for professional services, and other amounts received for personal
      services actually rendered in the course of employment with an Employer
      maintaining the Plan (including, but not limited to, commissions paid
      salesmen, compensation for services on the basis of a percentage of
      profits, commissions on insurance premiums, tips, bonuses, fringe
      benefits, and reimbursements or other expense allowances under a
      nonaccountable plan (as described in Regulation 1.62-2(c)) for a Plan
      Year.

            "415 Compensation" shall exclude (1)(A) contributions made by the
      Employer to a plan of deferred compensation to the extent that, before the
      application of the Code Section 415 limitations to the Plan, the
      contributions are not includable in the gross income of the Employee for
      the taxable year in which contributed, (B) Employer contributions made on
      behalf of an Employee to a simplified employee pension plan described in
      Code Section 408(k) to the extent such contributions are excludable from
      the Employee's gross income, (C) any distributions from a plan of deferred
      compensation, including the TPC Cash Bonus Plan and the TPC Bonus and
      Profit Sharing Plan; (2) amounts realized from the exercise of a
      non-qualified stock option or when restricted stock (or property) held by
      an Employee either becomes freely transferable or is no longer subject to
      a substantial risk of forfeiture; (3) amounts realized from the sale,
      exchange, or other disposition of stock acquired under a qualified stock
      option; and (4) other amounts that receive special tax benefits, such as
      premiums for group term life insurance (but only to the extent that the
      premiums are not in cludable in the gross income of the Employee), or
      contributions made by the Employer (whether or not under a salary
      reduction agreement) towards the purchase of any annuity contract
      described in Code Section 403(b) (whether or not the contributions are
      excludable from the gross income of the Employee). "415 Compensation"
      shall be limited to $150,000 (unless adjusted in the same manner as
      permitted under Code Section 415(d)).

            (f) For purposes of applying the limitations of Code Section 415,
      the "limitation year" shall be the Plan Year.

                                      -24-

            (g) The dollar limitation under Code Section 415(b)(1)(A) stated in
      paragraph (a)(1) above shall be adjusted annually as provided in Code
      Section 415(d) pursuant to the Regulations. The adjusted limitation is
      effective as of January 1st of each calendar year and is applicable to
      "limitation years" ending with or within that calendar year.

            (h) For the purpose of this Section, all qualified defined benefit
      plans (whether terminated or not) ever maintained by the Employer shall be
      treated as one defined benefit plan, and all qualified defined
      contribution plans (whether terminated or not) ever maintained by the
      Employer shall be treated as one defined contribution plan.

            (i) For the purpose of this Section, if the Employer is a member of
      a controlled group of corporations, trades or businesses under common
      control (as defined by Code Section 1563(a) or Code Section 414(b) and (c)
      as modified by Code Section 415(h)), is a member of an affiliated service
      group (as defined by Code Section 414(m)), or is a member of a group of
      entities required to be aggregated pursuant to Regulations under Code
      Section 414(o), all Employees of such Employers shall be considered to be
      employed by a single Employer.

            (j) For the purpose of this Section, if this Plan is a Code Section
      413(c) plan, all Employers of a Participant who maintain this Plan will be
      considered to be a single Employer.

            (k) (1) If a Participant participates in more than one defined
            contribution plan maintained by the Employer which have different
            Anniversary Dates, the maximum "annual additions" under this Plan
            shall equal the maximum "annual additions" for the "limitation year"
            minus any "annual additions" previously credited to such
            Participant's accounts during the "limitation year."

                  (2) If a Participant participates in both a defined
            contribution plan subject to Code Section 412 and a defined
            contribution plan not subject to Code Section 412 maintained by the
            Employer which have the same Anniversary Date, "annual additions"
            will be credited to the Participant's accounts under the defined
            contribution plan subject to Code Section 412 prior to crediting
            "annual additions" to the Participant's accounts under the defined
            contribution plan not subject to Code Section 412.

                  (3) If a Participant participates in more than one defined
            contribution plan not subject to Code Section 412 maintained by the
            Employer which have the same Anniversary Date, the maximum "annual
            additions" under this Plan shall equal the product of (A) the
            maximum "annual additions" for the "limitation year" minus any
            "annual additions" previously credited under subparagraphs (1) or
            (2) above, multiplied by (B) a fraction (i) the numerator of which
            is the "annual additions" which would be credited to such
            Participant's accounts under this Plan without regard to the
            limitations of Code Section 415 and (ii) the denominator of which is
            such "annual additions" for all plans described in this
            subparagraph.

                                      -25-

            (l) If an Employee is (or has been) a Participant in one or more
      defined benefit plans and one or more defined contribution plans
      maintained by the Employer, the sum of the defined benefit plan fraction
      and the defined contribution plan fraction for any "limitation year" may
      not exceed 1.0.

            (m) The defined benefit plan fraction for any "limitation year" is a
      fraction, the numerator of which is the sum of the Participant's projected
      annual benefits under all the defined benefit plans (whether or not
      terminated) maintained by the Employer, and the denominator of which is
      the lesser of 125 percent of the dollar limitation determined for the
      "limitation year" under Code Sections 415(b) and (d) or 140 percent of the
      highest average compensation, including any adjustments under Code Section
      415(b).

            Notwithstanding the above, if the Participant was a Participant as
      of the first day of the first "limitation year" beginning after December
      31, 1986, in one or more defined benefit plans maintained by the Employer
      which were in existence on May 6, 1986, the denominator of this fraction
      will not be less than 125 percent of the sum of the annual benefits under
      such plans which the Participant had accrued as of the close of the last
      "limitation year" beginning before January 1, 1987, disregarding any
      changes in the terms and conditions of the plan after May 5, 1986. The
      preceding sentence applies only if the defined benefit plans individually
      and in the aggregate satisfied the requirements of Code Section 415 for
      all "limitation years" beginning before January 1, 1987.

            (n) The defined contribution plan fraction for any "limitation year"
      is a fraction, the numerator of which is the sum of the annual additions
      to the Participant's Account under all the defined contribution plans
      (whether or not terminated) maintained by the Employer for the current and
      all prior "limitation years" (including the annual additions attributable
      to the Participant's nondeductible Employee contributions to all defined
      benefit plans, whether or not terminated, maintained by the Employer, and
      the annual additions attributable to all welfare benefit funds, as defined
      in Code Section 419(e), and individual medical accounts, as defined in
      Code Section 415(l)(2), maintained by the Employer), and the denominator
      of which is the sum of the maximum aggregate amounts for the current and
      all prior "limitation years" of service with the Employer (regardless of
      whether a defined contribution plan was maintained by the Employer). The
      maximum aggregate amount in any "limitation year" is the lesser of 125
      percent of the dollar limitation determined under Code Sections 415(b) and
      (d) in effect under Code Section 415(c)(1)(A) or 35 percent of the
      Participant's Compensation for such year.

            If the Employee was a Participant as of the end of the first day of
      the first "limitation year" beginning after December 31, 1986, in one or
      more defined contribution plans maintained by the Employer which were in
      existence on May 6, 1986, the numerator of this fraction will be adjusted
      if the sum of this fraction and the defined benefit fraction would
      otherwise exceed 1.0 under the terms of this Plan. Under the adjustment,
      an amount equal to the product of (1) the excess of the sum of the
      fractions over 1.0 times (2) the denominator of this fraction, will be
      permanently subtracted from the numerator of this fraction. The adjustment
      is calculated using the fractions as they would be computed as of the end
      of the

                                      -26-

      last "limitation year" beginning before January 1, 1987, and disregarding
      any changes in the terms and conditions of the Plan made after May 5,
      1986, but using the Code Section 415 limitation applicable to the first
      "limitation year" beginning on or after January 1, 1987. The annual
      addition for any "limitation year" beginning before January 1, 1987 shall
      not be recomputed to treat all Employee contributions as annual additions.

            (o) Notwithstanding the foregoing, for any "limitation year" in
      which the Plan is a Top Heavy Plan, 100 percent shall be substituted for
      125 percent in paragraph (l) and (m) unless the extra minimum allocation
      is being provided pursuant to Section 4.3(i). However, for any "limitation
      year" in which the Plan is a Super Top Heavy Plan, 100 percent shall be
      substituted for 125 percent in any event.

            (p) If the sum of the defined benefit plan fraction and the defined
      contribution plan fraction shall exceed 1.0 in any "limitation year" for
      any Participant in this Plan, the Administrator shall limit, to the extent
      necessary, the "annual additions" to such Participant's accounts for such
      "limitation year." If, after limiting the "annual additions" to such
      Participant's accounts for the "limitation year," the sum of the defined
      benefit plan fraction and the defined contribution plan fraction still
      exceed 1.0, the Administrator shall then adjust the numerator of the
      defined benefit plan fraction so that the sum of both fractions shall not
      exceed 1.0 in any "limitation year" for such Participant.

            (q) Notwithstanding anything contained in this Section to the
      contrary, the limitations, adjustments and other requirements prescribed
      in this Section shall at all times comply with the provisions of Code
      Section 415 and the Regulations thereunder, the terms of which are
      specifically incorporated herein by reference.

      4.5   ADJUSTMENT FOR EXCESSIVE ANNUAL ADDITIONS

            (a) If, as a result of the allocation of Forfeitures a reasonable
      error in estimating a Participant's Compensation or other facts and
      circumstances to which Regulation 1.415-6(b)(6) shall be applicable, the
      "annual additions" under this Plan would cause the maximum "annual
      additions" to be exceeded for any Participant, the Administrator shall (1)
      hold any "excess amount" remaining after the return of any voluntary
      Employee contributions in a "Section 415 suspense account" (2) allocate
      and reallocate the "Section 415 suspense account" in the next "limitation
      year" (and succeeding "limitation years" if necessary) to all Participants
      in the Plan before any Employer or Employee contributions which would
      constitute "annual additions" are made to the Plan for such "limitation
      year" or (3) reduce Employer Contributions to the Plan for such
      "limitation year" by the amount of the "Section 415 suspense account"
      allocated and reallocated during such "limitation year".

            (b) For purposes of this Article, "excess amount" for any
      Participant for a "limitation year" shall mean the excess, if any, of (1)
      the "annual additions" which would be credited to his account under the
      terms of the Plan without regard to the limitations of Code Section 415
      over (2) the maximum "annual additions" determined pursuant to Section
      415.

                                      -27-

            (c) For purposes of this Section, "Section 415 suspense account"
      shall mean an unallocated account equal to the sum of "excess amounts" for
      all Participants in the Plan during the "limitation year". The "Section
      415 suspense account" shall not share in any earnings or losses of the
      Trust Fund.

            (d)   The Plan may not distribute "excess amounts" to Participants
      or Former Participants.

      4.6   DIRECTED INVESTMENT ACCOUNT

            (a) Each "Qualified Participant" may elect within ninety (90) days
      after the close of each Plan Year during the "Qualified Election Period"
      to direct the Administrator in writing as to the investment of at least 25
      percent of the Participant's Company Stock Account (to the extent such
      portion exceeds the amount to which a prior election under this
      subparagraph applies). In the case of the election year in which the
      Participant can make his last election, the preceding sentence shall be
      applied by substituting "50 percent" for "25 percent". If the "Qualified
      Participant" elects to direct the Administrator as to the investment of
      his Company Stock Account, such direction shall be effective no later than
      180 days after the close of the Plan Year to which such direction applies.
      In lieu of directing the Administrator as to the investment of his Company
      Stock Account, the "Qualified Participant" may elect a distribution in
      cash or Company Stock of the portion of his Company Stock Account covered
      by the election within ninety (90) days after the last day of the period
      during which the election can be made. Any such distribution of Company
      Stock shall be subject to Section 7.11.

            (b)   For the purposes of this Section the following definitions
      shall apply:

                  (1) "Qualified Participant" means any Participant or Former
            Participant who has completed ten (10) Years of Service as a
            Participant and has attained age 55.

                  (2) "Qualified Election Period" means the five (5) Plan Year
            period beginning with the Plan Year after the Plan Year in which the
            Participant attains age 55 (or, if later, beginning with the Plan
            Year after the first Plan Year in which the Participant first became
            a "Qualified Participant").

            (c) A separate Directed Investment Account shall be established for
      each Participant who has directed an investment. Transfers between the
      Participant's regular account and his Directed Investment Account shall be
      charged and credited as the case may be to each account. The Directed
      Investment Account shall not share in Trust Fund earnings, but it shall be
      charged or credited as appropriate with the net earnings, gains, losses
      and expenses as well as any appreciation or depreciation in market value
      during each Plan Year attributable to such account. To the extent so
      directed, the Administrators are relieved of their fiduciary
      responsibilities as provided in Section 404 of the Act.

                                      -28-

            (d) Each Qualified Participant may direct the Administrator to
      separate and keep separate all or a portion of his share of his Company
      Stock Account; and further each Qualified Participant is authorized and
      empowered, in his sole and absolute discretion, to give directions to the
      Administrator in such form as the Administrator may require concerning the
      investment of the Participant's Directed Investment Account, which
      directions must be followed by the Administrator. The Administrator shall
      be under any duty to question any such direction of the Participant or to
      review any securities or other property, real or personal, or to make any
      suggestions to the Participant in connection therewith, and the Trustee
      shall comply as promptly as practicable with directions given by the
      Qualified Participant hereunder. Any such direction may be of a continuing
      nature or otherwise and may be revoked by the Participant at any time in
      such form as the Administrator may require. The Administrator shall not be
      responsible or liable for any loss or expense which may arise from or
      result from compliance with any directions from the Participant nor shall
      the Administrator be responsible for, or liable for any loss or expense
      which may result from the Administrator's refusal or failure to comply
      with any directions from the Participant. Any costs and expenses related
      to compliance with the Qualified Participant's directions shall be borne
      by the Participant's Directed Investment Account.

      4.7   SUSPENSE ACCOUNT

      All Employer Contributions, Forfeitures and net income (or net loss) of
the Trust Fund shall be held in a suspense account until allocated to the
applicable Participants' Accounts.

                                      -29-

                          FUNDING AND INVESTMENT POLICY

      5.1   INVESTMENT POLICY

            (a)   The Plan is designed to invest primarily in Company Stock.

            (b) With due regard to subparagraph (a) above, the Administrator may
      direct the Trustee to invest funds under the Plan in other property as
      described in the Trust Agreement or direct the Trustee to hold such funds
      in cash or cash equivalents.

            (c) The Plan may not obligate itself to acquire Company Stock from a
      particular holder thereof at an indefinite time determined upon the
      happening of an event such as the death of the holder.

            (d) The Plan may not obligate itself to acquire Company Stock under
      a put option binding upon the Plan. However, at the time a put option is
      exercised, the Plan may be given an option to assume the rights and
      obligations of the Employer under a put option binding upon the Employer.

            (e) All purchases or sales of Company Stock and the price of such
      purchases or sales shall be made as the Administrator instructs the
      Trustee. All purchases of Company Stock shall be made at a price which, in
      the judgment of the Administrator, does not exceed the fair market value
      thereof. All sales of Company Stock shall be made at a price which, in the
      judgment of the Administrator, is not less than the fair market value
      thereof. The valuation rules set forth in Article VI shall be applicable.

      5.2   APPLICATION OF CASH

      Employer Contributions received by the Trust Fund shall first be applied
to pay any Current Obligations of the Trust Fund.

      5.3   TRANSACTIONS INVOLVING COMPANY STOCK

            (a) No portion of the Trust Fund attributable to (or allocable in
      lieu of) Company Stock acquired by the Plan in a sale to which Code
      Section 1042 or Code Section 2057 applies may accrue or be allocated
      directly or indirectly under any plan maintained by the Employer meeting
      the requirements of Code Section 401(a):

                  (1)   during the "Nonallocation Period", for the benefit of;

                       (i)any taxpayer who makes an election under Code Section
                  1042(a) with respect to Company Stock or any decedent if the
                  executor of the estate of the decedent makes a qualified sale
                  to which Code Section 2057 applies,

                                      -30-

                      (ii)any individual who is related to the taxpayer or the
                  decedent (within the meaning of Code Section 267(b)), or

                  (2)   for the benefit of any other person who owns
            (after application of Code Section 318(a)) more than 25 percent of;

                      (i)any class of outstanding stock of the Employer which
                  issued such Company Stock, or

                      (ii)the total value of any class of outstanding stock of
                  the Employer.

            (b) Except, however, subparagraph (a)(1)(ii) above shall not apply
      to lineal descendants of the taxpayer, provided that, the aggregate amount
      allocated to the benefit of all such lineal descendants during the
      "Nonallocation Period" does not exceed more than five (5) percent of the
      Company Stock (or amounts allocated in lieu thereof) held by the Plan
      which are attributable to a sale to the Plan by any person related to such
      descendants (within the meaning of Code Section 267(c)(4)) in a
      transaction to which Code Section 1042 applied.

            (c) A person shall be treated as failing to meet the stock ownership
      limitation under paragraph (a)(2) above if such person fails such
      limitation:

                  (1)   at any time during the one (1) year period ending on the
            date of sale of Company Stock to the Plan, or

                  (2)   on the date as of which Company Stock is allocated to 
            Participants in the Plan.

            (d) For purposes of this Section, "Nonallocation Period" means the
      ten (10) year period beginning on the later of:

                  (1)   the date of the sale of the Company Stock, or

                  (2) the date of the Plan allocation attributable to the final
            payment of the Exempt Loan incurred in connection with such sale.

      5.4   LOANS TO THE TRUST

            (a) The Plan may, but only upon the direction of the Administrator,
      borrow money for any lawful purpose, provided, the proceeds of an Exempt
      Loan are used within a reasonable time after receipt only for any or all
      of the following purposes:

                  (1)   To acquire Company Stock.

                  (2)   To repay such loan.

                                      -31-

                  (3)   To repay a prior Exempt Loan.

            (b) All loans to the Trust which are made or guaranteed by a
      disqualified person must satisfy all requirements applicable to Exempt
      Loans including but not limited to the following:

                  (1)   The loan must be at a reasonable rate of interest;

                  (2) Any collateral pledged to the creditor by the Plan shall
            consist only of the Company Stock purchased with the borrower funds;

                  (3) Under the terms of the loan, any pledge of Company Stock
            shall provide for the release of shares so pledged on a pro-rata
            basis pursuant to Section 4.3(g);

                  (4) Under the terms of the loan, the creditor shall have no
            recourse against the Plan except with respect to such collateral,
            earnings attributable to such collateral, Employer Contributions
            (other than contributions of Company Stock) that are made to meet
            Current Obligations and earnings attributable to such contributions;

                  (5) The loan must be for a specific term and may not be
            payable at the demand of any person, except in the cause of a
            default.

                  (6) In the event of default upon an Exempt Loan, the value of
            the Trust Fund transferred in satisfaction of the Exempt Loan shall
            not exceed the amount of default. If the lender is a disqualified
            person, an Exempt Loan shall provide for a transfer of Trust Funds
            upon default only upon and to the extent of the failure of the Plan
            to meet the payment schedule of the Exempt Loan;

                  (7) Exempt Loan payments during a Plan Year must not exceed an
            amount equal to: (A) the sum, over all Plan Years, of all Employer
            Contributions made by the Employer to the Plan with respect to such
            Exempt Loan and earnings on such Employer Contributions, less (B)
            the sum of the Exempt Loan payments in all preceding Plan Years. A
            separate accounting shall be maintained for such Employer
            Contributions and earnings until the Exempt Loan is repaid.

            (c) The term "disqualified person" means a person who is a
      Fiduciary, a person providing services to the Plan, an Employer, any of
      whose Employees are covered by the Plan, an employee organization any of
      whose members are covered by the Plan, an owner, direct or indirect, of
      50% or more of the total combined voting power of all classes of voting
      stock, or an officer, director, 10% or more shareholder, or a Highly
      Compensated Employee.

                                   ARTICLE VI
                                   VALUATIONS

      6.1   VALUATION OF THE TRUST FUND

      The Administrator shall direct the Trustee, as of each Anniversary Date,
and at such other date or dates deemed necessary by the Administrator, herein
called "valuation date", to determine the net worth of the assets comprising the
Trust Fund, other than Company Stock, as it exists on the "valuation date" prior
to taking into consideration any contribution to be allocated for that Plan
Year. In determining such net worth, the Trustee shall value the assets
comprising the Trust Fund, other than Company Stock, at their fair market value
as of the "valuation date" and shall deduct all expenses for which the Trustee
has not yet obtained reimbursement from the Employer or the Trust Fund. The
Administrator shall have the duty of determining the fair market value of
Company Stock.

      6.2   METHOD OF VALUATION

      Valuations must be made in good faith and based on all relevant factors
for determining the fair market value of securities. In the case of a
transaction between a Plan and a disqualified person, value must be determined
as of the date of the transaction. For all other Plan purposes, value must be
determined as of the most recent valuation date under the Plan. An independent
appraisal will not in itself be a good faith determination of value in the case
of a transaction between the Plan and a disqualified person. However, in other
cases, a determination of fair market value based on at least an annual
appraisal independently arrived at by a person who customarily makes such
appraisals and who is independent of any party to the transaction will be deemed
to be a good faith determination of value. Company Stock not readily tradeable
on an established securities market shall be valued by an independent appraiser
appointed by the Administrator meeting requirements similar to the requirements
of the Regulations prescribed under Code Section 170(a)(1).

                                      -33-

                                   ARTICLE VII
                   DETERMINATION AND DISTRIBUTION OF BENEFITS

      7.1   BENEFITS UPON RETIREMENT

      A Participant who terminates his employment on or after his Normal
Retirement Date shall be distributed a benefit in accordance with Section 7.5
equal in value to the balance in the Participant's Accounts as of his Benefit
Commencement Date, such balance to be determined as of the Valuation Date
immediately preceding the Participant's Benefit Commencement Date.

      7.2   BENEFITS UPON DEATH

            (a) Upon the death of a Participant before his Normal Retirement
      Date or other termination of his employment, the Participant's Beneficiary
      shall be distributed a benefit in accordance with Section 7.5 equal in
      value to the balance in the Participant's Accounts as of the Benefit
      Commencement Date to the Beneficiary, such balance to be determined as of
      the Valuation Date immediately preceding such Benefit Commencement Date.

            (b) The Administrator may require such proper proof of death and
      such evidence of the right of any person to receive payment of the value
      of the account of a deceased Participant as the Administrator may deem
      desirable. The Administrator's determination of death and of the right of
      any person to receive payment shall be conclusive.

            (c) The Beneficiary of the death benefit payable pursuant to this
      Section shall be the Participant's spouse; provided, however, the
      Participant may designate a Beneficiary other than his spouse if:

                  (1)  the spouse has waived her right to be the Participant's 
            Beneficiary, or

                  (2)  the Participant has no spouse, or

                  (3)  the spouse cannot be located.

            In such event, the designation of a Beneficiary shall be made on a
      form satisfactory to the Administrator. A Participant may at any time
      revoke his designation of a Beneficiary or change his Beneficiary by
      filing written notice of such revocation or change with the Administrator.
      However, the Participant's spouse must again consent in writing to any
      such change or revocation unless the original consent acknowledged that
      the spouse had the right to limit consent only to a specific Beneficiary
      and that the spouse voluntarily elected to relinquish such right. In the
      event no valid designation of Beneficiary exists at the time of the
      Participant's death, the death benefit shall be payable to his estate.

            (d) Any consent by the Participant's spouse to waive any rights to
      the death benefit must be in writing, must acknowledge the effect of such
      waiver, and be witnessed by

                                      -34-

      a Plan representative or a notary public. Further, the spouse's consent
      must be irrevocable and must acknowledge the specific nonspouse
      Beneficiary.

      7.3   BENEFITS UPON DISABILITY

      In the event a Participant's employment is terminated due to a Total and
Permanent Disability prior to his Normal Retirement Date or other termination of
his employment, such Participant shall be distributed a benefit in accordance
with Section 7.5 equal in value to the balance in the Participant's Accounts as
of his Benefit Commencement Date, such balance to be determined as of the
Valuation Date immediately preceding his Benefit Commencement Date.

      7.4   BENEFITS UPON TERMINATION

            (a) Each Participant whose employment is terminated for any reason
      other than Total and Permanent Disability, retirement or death shall be
      distributed a benefit in accordance with Section 7.5 equal in value to the
      sum of his Vested interest in the balance of his Participant's Accounts as
      of his Benefit Commencement Date, such balance to be determined as of the
      Valuation Date immediately preceding his Benefit Commencement Date.

            (b) For purposes of this Section, a Participant's Vested interest in
      Participant's Accounts shall be determined by such Participant's years of
      Vesting Service in accordance with the following schedule:

            YEARS OF VESTING SERVICE            VESTED INTEREST

                Less than 1 year                       0%
                1 year                                20%
                2 years                               40%
                3 years                               60%
                4 years                               80%
                5 years                              100%

            If a portion of a Participant's Account is forfeited, Company Stock
      allocated to the Participant's Company Stock Account must be forfeited
      only after the Participant's Other Investments Account has been depleted.
      If interest in more than one class of Company Stock has been allocated to
      a Participant's Account, the Participant must be treated as forfeiting the
      same proportion of each such class.

            (c) The computation of a Participant's nonforfeitable percentage of
      his interest in the Plan shall not be reduced as the result of any direct
      or indirect amendment to this Article. In the event that the Plan is
      amended to change or modify any vesting schedule, a Participant with a
      least three (3) Years of Service as of the expiration date of the election
      period may elect to have his nonforfeitable percentage computed under the
      Plan without regard to such amendment. If a Participant fails to make such
      election, then such Participant

                                      -35-

      shall be subject to the new vesting schedule. The Participant's election
      period shall commence on the adoption date of the amendment and shall end
      60 days after the latest of:

                  (1)   the adoption date of the amendment,

                  (2)   the effective date of the amendment, or

                  (3) the date the Participant receives written notice of the
            amendment from the Employer or Administrator.

            (d) Paragraph (b) above not withstanding, a Participant shall have a
      100% Vested interest in his Participant's Accounts upon attainment of his
      Normal Retirement Date.

            (e) (1) If any Former Participant shall be reemployed by the
            Employer before a 1-Year Break in Service occurs, he shall continue
            to participate in the Plan in the same manner as if such termination
            had not occurred.

                  (2) If any Former Participant shall be reemployed by the
            Employer before five (5) consecutive 1-Year Breaks in Service, and
            such Former Participant had received a distribution of his entire
            Vested interest prior to his reemployment, his forfeited account
            shall be reinstated only if he repays the full amount distributed to
            him before the earlier of five (5) years after the first date on
            which the Participant is subsequently reemployed by the Employer or
            the close of the first period of 5 consecutive 1-Year Breaks in
            Service commencing after the distribution. In the event the Former
            Participant does repay the full amount distributed to him, the
            undistributed portion of the Participant's Account must be restored
            in full, unadjusted by any gains or losses occurring subsequent to
            the Anniversary Date or other valuation date preceding his
            termination.

                  (3) If any Former Participant is reemployed after a 1-Year
            Break in Service has occurred, Years of Service shall include Years
            of Service prior to his 1-Year Break in Service subject to the
            following rules:

                        (i) If a Former Participant has a 1-Year Break in
                  Service, his pre- break and post-break service shall be used
                  for computing Years of Service for eligibility and for vesting
                  purposes only after he has been employed for one (1) Year of
                  Service following the date of his reemployment with the
                  Employer;

                        (ii) Any Former Participant who under the Plan does not
                  have a nonforfeitable right to any interest in the Plan
                  resulting from Employer Contributions shall lose credits
                  otherwise allowable under (i) above if his consecutive 1-Year
                  Breaks in Service equal or exceed the greater of (A) five (5)
                  or (B) the aggregate number of his pre-break Years of Service;

                                      -36-

                        (iii) After five (5) consecutive 1-Year Breaks in
                  Service, a Former Participant's Vested Account balance
                  attributable to pre-break service shall not be increased as a
                  result of post-break service;

                        (iv) If a Former Participant who has not had his Years
                  of Service before a 1-Year Break in Service disregarded
                  pursuant to (ii) above completes one (1) Year of Service for
                  eligibility purposes following his reemployment with the
                  Employer, he shall participate in the Plan retroactively from
                  his date of reemployment;

                        (v) If a Former Participant who has not had his Years of
                  Service before a 1-Year Break in Service disregarded pursuant
                  to (ii) above completes one (1) Year of Service for
                  eligibility purposes following his reemployment with the
                  Employer (a 1-Year Break in Service previously occurred, but
                  employment had not terminated), he shall participate in the
                  Plan retroactively from his reemployment commencement date.

      7.5   DISTRIBUTION OF BENEFITS

            (a) Except as provided in paragraph (c) below, payment of
      Participant's benefit hereunder shall be made as soon as administratively
      feasible after the Valuation Date coincident or next succeeding the date
      the Participant or his Beneficiary becomes entitled to a benefit pursuant
      to Sections 7.1, 7.2, 7.3 or 7.4.

            (b) The Administrator, pursuant to the election of the Participant
      (or if no election has been made prior to the Participant's death, by his
      Beneficiary), shall direct the Trustee to distribute to a Participant or
      his Beneficiary any amount to which he is entitled under the Plan in one
      or more of the following methods:

                  (1)   One lump-sum payment;

                  (2) Payments over a period certain in monthly, quarterly,
            semiannual, or annual installments. The period over which such
            payment is to be made shall not extend beyond the earlier of the
            Participant's life expectancy (or the life expectancy of the
            Participant and his designated Beneficiary) or the limited
            distribution period provided for in Section 7.5(c).

            (c) Notwithstanding the above, the Administrator may, unless the
      Participant elects (with the consent of the Participant's spouse) in
      writing a longer distribution period, distribute to a Participant or his
      Beneficiary Company Stock in substantially equal monthly, quarterly,
      semiannual, or annual installments over a period not longer than five (5)
      years. In the case of a Participant with an account balance in the Plan in
      excess of $500,000, the five (5) year period shall be extended one (1)
      additional year (but not more than five (5) addi tional years) for each
      $100,000 or fraction thereof by which such balance exceeds $500,000. The
      dollar limits shall be adjusted at the same time and in the same manner as
      provided in

                                      -37-

      Code Section 415(d). Notwithstanding the above, the Administrator may,
      unless Participant elects (with the consent of the Participant's spouse) a
      later distribution date, commence distribution of the Participant's
      Company Stock Account balance not later than one year after the close of
      the Plan Year (i) in which the Participant separates from service on
      account of retirement, Total and Permanent Disability or death, or (ii)
      which is the fifth Plan Year following the Plan Year in which the
      Participant otherwise separates from service; provided, however, any
      Company Stock allocated to a Participant's Company Stock Account purchased
      by means of an Exempt Loan may not be distributed until after such Exempt
      Loan is repaid in full.

            (d) Any distribution to a Participant who has a benefit which
      exceeds, or has ever exceeded, $3,500 at the time of any prior
      distribution shall require such Participant's consent if such distribution
      commences prior to the later of his Normal Retirement Age or age 62.
      With regard to this required consent:

                  (1) The Participant must be informed of his right to defer
            receipt of the distribution. If a Participant fails to consent, it
            shall be deemed an election to defer the commencement of payment of
            any benefit. However, any election to defer the receipt of benefits
            shall not apply with respect to distributions which are required
            under Section 7.5(h).

                  (2) Notice of the rights specified under this paragraph shall
            be provided no less than 30 days and no more than 90 days before the
            first day on which all events have occurred which entitle the
            Participant to such benefit.

                  (3) Written consent of the Participant to the distribution
            must not be made before the Participant receives the notice and must
            not be made more than 90 days before the first day on which all
            events have occurred which entitle the Participant to such benefit.

                  (4) No consent shall be valid if a significant detriment is
            imposed under the Plan on any Participant who does not consent to
            the distribution.

            If the value of a Participant's benefit does not exceed $3,500 and
      has never exceeded $3,500 at the time of any prior distribution, the
      Administrator may direct the Trustee to cause the entire benefit to be
      paid to such Participant without regard to Participant's election or the
      consent of the spouse.

            (e) Notwithstanding anything herein to the contrary, cash dividends
      on shares of Company Stock allocated to Participants' Accounts may be paid
      to Participants or their Beneficiaries, as determined in the sole
      discretion of the Administrator, within 90 days after the close of the
      Plan Year in which the dividend is paid.

            (f) Except as limited by Sections 7.5 and 7.6, whenever the Trustee
      is to make a distribution or to commence a series of payments on or before
      an Anniversary Date, the

                                      -38-

      distribution or series of payments may be made or begun on such date or as
      soon thereafter as is practicable, but in no event later than 180 days
      after the Anniversary Date. Except, however, unless a Former Participant
      elects in writing to defer the receipt of benefits (such election may not
      result in a death benefit that is more than incidental), the payment of
      benefits shall begin not later than the 60th day after the close of the
      Plan Year in which the latest of the following events occurs:

                  (1)   the date on which the Participant attains the Normal
            Retirement Age specified herein,

                  (2)   the 10th anniversary of the year in which the
            Participant commenced participation in the Plan, or

                  (3)   the date the Participant terminates his service with 
            the Employer.

            (g) Any part of a Participant's benefit which is retained in the
      Plan after the Anniversary Date on which his participation ends will
      continue to be treated as a Company Stock Account or as an Other
      Investments Account as provided in Article IV. However, neither account
      will be credited with any further Employer Contributions or Forfeitures.

            (h) Notwithstanding any provision in the Plan to the contrary, the
      distribution of a Participant's benefits shall be made in accordance with
      the following requirements and shall otherwise comply with Code Section
      401(a)(9) and the Regulations thereunder (inclu ding Regulation Section
      1.401(a)(9)-2), the provisions of which are incorporated herein by
      reference:

                  (1) A Participant's benefits shall be distributed to him not
            later than April 1st of the calendar year following the later of (i)
            the calendar year in which the Participant attains age 70 1/2 or
            (ii) the calendar year in which the Participant retires, provided,
            however, that this clause (ii) shall not apply in the case of a
            Participant who is a "five (5) percent owner" at any time during the
            five (5) Plan Year period ending in the calendar year in which he
            attains age 70 1/2 or, in the case of a Participant who becomes a
            "five (5) percent owner" during any subsequent Plan Year, clause
            (ii) shall no longer apply and the required beginning date shall be
            the April 1st of the calendar year following the calendar year in
            which such subsequent Plan Year ends. Alternatively, distributions
            to a Participant must begin no later than the applicable April 1st
            as determined under the preceding sentence and must be made over a
            period certain measured by the life expectancy of the Participant
            (or the life expectancies of the Participant and his designated
            Beneficiary) in accordance with Regulations. Notwithstanding the
            foregoing, clause (ii) above shall not apply to any Participant
            unless the Participant had attained age 70 1/2 before January 1,
            1988 and was not a "five (5) percent owner" at any time during the
            Plan Year ending with or within the calendar year in which the
            Participant attained age 66 1/2 or any subsequent Plan Year.

                                      -39-

                  (2) Distributions to a Participant and his Beneficiaries shall
            only be made in accordance with the incidental death benefit
            requirements of Code Section 401(a)(9)(G) and the Regulations
            thereunder.

            (i) For purposes of this Section, the life expectancy of a
      Participant and a Participant's spouse may, at the election of the
      Participant or the Participant's spouse, be redetermined in accordance
      with Regulations. The election, once made, shall be irrevocable. If no
      election is made by the time distributions must commence, then the life
      expectancy of the Participant and the Participant's spouse shall not be
      subject to recalculation. Life expectancy and joint and last survivor
      expectancy shall be computed using the return multiples in Tables V and VI
      of Regulation 1.72-9.

      7.6   HOW PLAN BENEFITS WILL BE DISTRIBUTED

            (a) Distribution of a Participant's benefit may be made in cash or
      Company Stock or both, provided, however, that if a Participant or
      Beneficiary so demands, such benefit shall be distributed only in the form
      of Company Stock. Prior to making a distribution of benefits, the
      Administrator shall advise the Participant or his Beneficiary, in writing,
      of the right to demand that benefits be distributed solely in Company
      Stock. If the Participant or his Beneficiary fails to make such demand in
      writing within 90 days after receipt of such written notice, the
      Administrator shall direct the Trustee to make such distribution in such
      form as the Administrator, in his sole discretion, shall determine.

            Any distributions of cash hereunder shall be equal to Company Stock
      held in the Participant's Company Stock Account on the Anniversary Date
      subsequent to the event triggering a distribution, valued at the fair
      market price per share of Company Stock as determined in accordance with
      Article VI as of the Anniversary Date immediately prior to the
      distribution. For purposes of this Section, an "event triggering a
      distribution" shall include but not be limited to retirement, death,
      disability, termination of service and the election to commence receiving
      benefits hereunder pursuant to Section 7.5.

            (b) If a Participant or Beneficiary demands that benefits be
      distributed solely in Company Stock, distribution of a Participant's
      benefit will be made entirely in whole shares or other units of Company
      Stock. Any balance in a Participant's Other Investments Account will be
      applied to acquire for distribution the maximum number of whole shares or
      other units of Company Stock at the then fair market value. Any fractional
      unit value unexpended will be distributed in cash. If Company Stock is not
      available for purchase by the Trustee, then the Trustee shall hold such
      balance until Company Stock is acquired and then make such distribution,
      subject to Sections 7.5.

            (c) The Trustee will make distribution from the Trust only on
      instructions from the Administrator.

            (d) Notwithstanding anything contained herein to the contrary, if
      the Employer's charter or by-laws restrict ownership of substantially all
      shares of Company Stock to

                                      -40-

      Employees and the Trust Fund, as described in Code Section 409(h)(2), the
      Administrator, in his sole discretion, may distribute a Participant's
      Account entirely in cash without granting the Participant the right to
      demand distribution in shares of Company Stock or distribute entirely in
      Company Stock subject to a requirement that such Company Stock may be
      resold to the Employer pursuant to Section 7.11.

            (e) Except as otherwise provided herein, Company Stock distributed
      by the Trustee may be restricted as to sale or transfer by the by-laws or
      articles of incorporation of the Employer, provided restrictions are
      applicable to all Company Stock of the same class. If a Participant is
      required to offer the sale of his Company Stock to the Employer before
      offering to sell his Company Stock to a third party, in no event may the
      Employer pay a price less than that offered to the distributee by another
      potential buyer making a bona fide offer and in no event shall the Trustee
      pay a price less than the fair market value of the Company Stock.

            (f) Except as otherwise provided in this Article, a Participant is
      not entitled to any payment, withdrawal or distribution under the Plan
      during his participation. If any such partial distribution is made, the
      Participant's benefit when computed will be reduced by the amount of any
      such advance.

            (g) If Company Stock acquired with the proceeds of an Exempt Loan
      (described in Section 5.4 hereof) is available for distribution and
      consists of more than one class, a Participant or his Beneficiary must
      receive substantially the same proportion of each such class.

            (h) Notwithstanding any provision in the Plan to the contrary,
      distributions upon the death of a Participant shall be made in accordance
      with the following requirements and shall otherwise comply with Code
      Section 401(a)(9) and the Regulations thereunder. If it is determined,
      pursuant to Regulations, that the distribution of a Participant's interest
      has begun and the Participant dies before his entire interest has been
      distributed to him, the remaining portion of such interest shall be
      distributed at least as rapidly as under the method of distribution
      selected pursuant to Section 7.5 as of his date of death. If a Participant
      dies before he has begun to receive any distributions of his interest
      under the Plan or before distributions are deemed to have begun pursuant
      to Regulations, then his death benefit shall be distributed to his
      Beneficiaries by December 31st of the calendar year in which the fifth
      anniversary of his date of death occurs.

            However, in the event that the Participant's spouse (determined as
      of the date of the Participant's death) is his Beneficiary, then in lieu
      of the preceding rules, distributions must be made over a period not
      extending beyond the life expectancy of the spouse and must commence on or
      before the later of (1) December 31st of the calendar year immediately
      following the calendar year in which the Participant died; or (2) December
      31st of the calendar year in which the Participant would have attained 70
      1/2. If the surviving spouse dies before distributions to such spouse
      begin, then the 5-year distribution requirement of this section shall
      apply as if the spouse was the Participant.

                                      -41-

            (i) For purposes of this Section, the life expectancy of a
      Participant and a Par ticipant's spouse may, at the election of the
      Participant or the Participant's spouse, be redetermined in accordance
      with Regulations. The election, once made, shall be irrevocable. If no
      election is made by the time distributions must commence, then the life
      expectancy of the Participant and the Participant's spouse shall not be
      subject to recalculation. Life expectancy and joint and last survivor
      expectancy shall be computed using the return multiples in Tables V and VI
      of Regulation 1.72-9.

      7.7   DISTRIBUTION FOR MINOR BENEFICIARY

      In the event a distribution is to be made to a minor, then the
Administrator may direct that such distribution be paid to the legal guardian,
or if none, to a parent of such Beneficiary, or to the custodian for such
Beneficiary under the Uniform Gift to Minors Act or Gift to Minors act, if such
is permitted by the laws of the state in which said Beneficiary resides. Such a
payment to the legal guardian, custodian or parent of a minor Beneficiary shall
fully discharge the Trustee, Employer, and Plan from further liability on
account thereof.

      7.8   LOCATION OF PARTICIPANT OR BENEFICIARY UNKNOWN

      In the event that all, or any portion, of the distribution payable to a
Participant or his Beneficiary hereunder shall, at the expiration of five (5)
years after it shall become payable, remain unpaid solely by reason of the
inability of the Administrator, after sending a registered letter, return
receipt requested, to the last known address, and after further diligent effort,
to ascertain the whereabouts of such Participant or his Beneficiary, the amount
so distributable shall be treated as a Forfeiture pursuant to the Plan. In the
event a Participant or Beneficiary is located subsequent to his benefit being
reallocated, such benefit shall be restored.

      7.9   RIGHT OF FIRST REFUSAL

            (a) If any Participant, his Beneficiary or any other person to whom
      shares of Company Stock are distributed from the Plan (the "Selling
      Participant") shall, at any time, desire to sell some or all of such
      shares (the "Offered Shares") to a third party (the "Third Party"), the
      Selling Participant shall give written notice of such desire to the
      Administrator and the Employer, which notice shall contain the number of
      shares offered for sale, the proposed terms of the sale and the names and
      addresses of both the Selling Participant and Third Party. Both the Trust
      Fund and the Employer shall each have the right of first refusal for a
      period of fourteen (14) days from the date the Selling Participant gives
      such written notice to the Employer and the Administrator (such fourteen
      (14) day period to run concurrently against the Trust Fund and the
      Employer) to acquire the Offered Shares. As between the Trust Fund and the
      Employer, the Trust Fund shall have priority to acquire the shares
      pursuant to the right of first refusal. The selling price and terms shall
      be the same as offered by the Third Party.

            (b) If the Trust Fund and the Employer do not exercise their right
      of first refusal within the required fourteen (14) day period provided
      above, the Selling Participant shall

                                      -42-

      have the right, at any time following the expiration of such fourteen (14)
      day period, to dispose of the Offered Shares to the third Party' provided,
      however, that (i) no disposition shall be made to the Third Party on terms
      more favorable to the Third Party than those set forth in the written
      notice delivered by the Selling Participant above, and (ii) if such
      disposition shall not be made to a third party on the terms offered to the
      Employer and the Trust Fund, the offered Shares shall again be subject to
      the right of first refusal set forth above.

            (c) The closing pursuant to the exercise of the right of first
      refusal under Section 7.9(a) above shall take place at such place agreed
      upon between the Administrator and the Selling Participant, but not later
      than ten (10) days after the Employer or the Trust Fund shall have
      notified the Selling Participant of the exercise of the right of first
      refusal. At such closing, the Selling Participant shall deliver
      certificates representing the Offered Shares duly endorsed in blank for
      transfer, or with stock powers attached duly executed in blank with all
      required transfer tax stamps attached or provided for, and the Employer or
      the Trust Fund shall deliver the purchase price, or an appropriate portion
      thereof, to the Selling Participant.

            (d) Except as provided in this Paragraph (d), no Company Stock
      acquired with the proceeds of an Exempt Loan complying with the
      requirements of Section 5.4 hereof shall be subject to a right of first
      refusal. Company Stock, which is acquired with the proceeds of an Exempt
      Loan which is distributed to a Participant or Beneficiary shall be subject
      to the right of first refusal, provided for in Paragraph (a) of this
      Section only so long as the Company Stock is not publicly traded. The term
      "publicly traded" refers to a securities exchange registered under section
      6 of the Securities Exchange Act of 1934 (15 U.S.C. 78f) or that is quoted
      on a system sponsored by a national securities association registered
      under Section 15A(b) of the Securities Exchange Act (15 U.S.C. 780). In
      addition, in the case of Company Stock which was acquired with the
      proceeds of a loan described in Section 5.4, the selling price and other
      terms under the right must not be less favorable to the seller than the
      greater of the value of the security determined under Regulation
      54.4975-11(d)(5), or the purchase price and other terms offered by a buyer
      (other than the Employer or the Trust Fund), making a good faith offer to
      purchase the security. The right of first refusal must lapse no later than
      fourteen (14) days after the security holder gives notice to the holder of
      the right that an offer by a third party to purchase the security has been
      made. The right of first refusal shall comply with the provisions of
      Paragraphs (a), (b) and (c) of this Section, except to the extent those
      provisions may conflict with the provisions of this paragraph.

      7.10  STOCK CERTIFICATE LEGEND

      Certificates for shares distributed pursuant to the Plan shall contain the
      following legend:

      "The shares represented by this certificate are transferable only upon
      compliance with the terms of the TPC FINANCE CORP. EMPLOYEE STOCK 
      OWNERSHIP PLAN (to be renamed TEXAS PETROCHEMICALS CORPORATION EMPLOYEE
      STOCK

                                      -43-

      OWNERSHIP PLAN) originally effective as of July 1, 1996, a copy of said
      Plan being on file in the office of the Company."

      7.11  PUT OPTION

            (a) If Company Stock which was not acquired with the proceeds of an
      Exempt Loan is distributed to a Participant and such Company Stock is not
      readily tradeable on an established securities market, a Participant has a
      right to require the Employer to repurchase the Company Stock distributed
      to such Participant under a fair valuation formula. Such Stock shall be
      subject to the provisions of Section 7.11(c).

            (b) Company Stock which is acquired with the proceeds of an Exempt
      Loan and which is not publicly traded when distributed, or if it is
      subject to a trading limitation when distributed, must be subject to a put
      option. For purposes of this paragraph, a "trading limitation" on a
      Company Stock is a restriction under any Federal or State securities law
      or any regulation thereunder, or an agreement (not prohibited by Section
      7.12) affecting the Company Stock which would make the Company Stock not
      as freely tradeable as stock not subject to such restriction.

            (c) The put option must be exercisable only by a Participant, by the
      Participant's donees, or by a person (including an estate or its
      distributee) to whom the Company Stock passes by reason of a Participant's
      death. (Under this paragraph Participant or Former Participant means a
      Participant or Former Participant and the beneficiaries of the Participant
      or Former Participant under the Plan.) The put option must permit a
      Participant to put the Company Stock to the Employer. Under no
      circumstances may the put option bind the Plan. However, it shall grant
      the Plan an option to assume the rights and obligations of the Employer at
      the time that the put option is exercised. If it is known at the time a
      loan is made that Federal or state law will be violated by the Employer's
      honoring such put option, the put option must permit the Company Stock to
      be put, in a manner consistent with such law, to a third party (E.G., an
      affiliate of the Employer or a shareholder other than the Plan) that has
      substantial net worth at the time the loan is made and whose net worth is
      reasonably expected to remain substantial.

            The put option shall commence as of the day following the date the
      Company Stock is distributed to the former Participant and end 60 days
      thereafter and if not exercised within such 60-day period, an additional
      60-day option shall commence one year after the date the stock was
      distributed to the Former Participant (or such other 60-day period as
      provided in regulations promulgated by the Secretary of the Treasury).
      However, in the case of Company Stock that is publicly traded without
      restrictions when distributed but ceases to be so traded within either of
      the 60-day periods described herein after distribution, the Employer must
      notify each holder of such Company Stock in writing on or before the tenth
      day after the date the Company Stock ceases to be so traded that for the
      remainder of the applicable 60-day period the Company Stock is subject to
      the put option. The number of days between the tenth day and the date on
      which notice is actually given, if later than the tenth day, must be added
      to the duration of the put option. The notice must inform distributees of
      the terms

                                      -44-

      of the put options that they are to hold.  The terms must satisfy the
      requirements of this paragraph.

            The put option is exercised by the holder notifying the Employer in
      writing that the put option is being exercised; the notice shall state the
      name and address of the holder and the number of shares to be sold. The
      period during which a put option is exercisable does not include any time
      when a distributee is unable to exercise it because the party bound by the
      put option is prohibited from honoring it by applicable Federal or state
      law. The price at which a put option must be exercisable is the value of
      the Company Stock determined in accordance with Section 6.2. Payment under
      the put option involving a "Total Distribution" shall be paid in
      substantially equal monthly, quarterly, semiannual or annual installments
      over a period certain beginning not later than thirty (30) days after the
      exercise of the put option and not extending beyond (5) years. The
      deferral of payment is reasonable if adequate security and a reasonable
      interest rate on the unpaid amounts are provided. The amount to be paid
      under the put option involving installment distributions must be paid not
      later than thirty (30) days after the exercise of the put option. Payment
      under a put option must not be restricted by the provisions of a loan or
      any other arrangement, including the terms of the employer's articles of
      incorporation, unless so required by applicable state law.

            For purposes of this Section, "Total Distribution" means a
      distribution to a Participant or Former Participant within one taxable
      year of the entire Vested Participant's Account.

            (d) An arrangement involving the Plan that creates a put option must
      not provide for the issuance of put options other than as provided under
      this Section. The Plan (and the Trust Fund) must not otherwise obligate
      itself to acquire Company Stock from a particular holder thereof at an
      indefinite time determined upon the happening of an event such as the
      death of the holder.

      7.12  NONTERMINABLE PROTECTIONS AND RIGHTS

      No Company Stock, except as provided in Section 7.9(d) and Section
7.11(b), acquired with the proceeds of a loan described in Section 5.4 hereof
may be subject to a put, call, or other option, or buy-sell or similar
arrangement when held by and when distributed from the Trust Fund, whether or
not the Plan is then an ESOP. The protections and rights granted in this Section
are nonterminable, and such protections and rights shall continue to exist under
the terms of this Plan so long as any Company Stock acquired with the proceeds
of a loan described in Section 5.4 hereof is held by the Trust Fund or by a
Participant or other person for whose benefit such protections and rights have
been created, and neither the repayment of such loan nor the failure of the Plan
to be an ESOP, nor an amendment of the Plan shall cause a termination of said
protections and rights.

      7.13  LIMITATIONS ON BENEFITS AND DISTRIBUTIONS

      All rights and benefits, including elections, provided to a Participant in
this plan shall be subject to the rights afforded to any "alternate payee" under
a "qualified domestic relations order." Furthermore, a distribution to an
"alternate payee" shall be permitted if such distribution is

                                      -45-

authorized by a "qualified domestic relations order," even if the affected
Participant has not separated from service and has not reached the "earliest
retirement age" under the Plan. For purposes of this Section, "alternate payee,"
"qualified domestic relations order" and "earliest retirement age" shall have
the meaning set forth under Code Section 414(p).

      7.14  PAYMENT OF DISTRIBUTION DIRECTLY TO ELIGIBLE RETIREMENT
            PLAN

            (a) 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
      Administrator, to have any portion of an Eligible Rollover Distribution
      paid directly to an Eligible Retirement Plan specified by the Distributee
      in a Direct Rollover.

            (b)   For purposes of this Section the following definitions shall 
      apply:

                  (1) "Eligible Rollover Distribution": An Eligible Rollover
            Distribution is 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 specified period of ten years or more; any distribution to the
            extent such distribution is required under Section 401(a)(9) of the
            Code; and the portion of any distribution that is not includible in
            gross income (determined without regard to the exclusion for net
            unrealized appreciation with respect to employer securities).

                  (2) "Eligible Retirement Plan": An Eligible Retirement Plan is
            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, or a qualified trust described in Section 401(a) of the Code,
            that accepts the Distributee's Eligible Rollover Distribution.
            However, in the case of an Eligible Rollover Distribution to the
            surviving spouse, an Eligible Retirement Plan is an individual
            retirement account or individual retirement annuity.

                  (3) "Distributee": A Distributee includes an Employee or
            former Employee. In addition, the Employee's or former Employee's
            surviving spouse and the Employee's or former Employee'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.

                  (4)  "Direct Rollover":  A Direct Rollover is a payment by the
            Plan to the Eligible Retirement Plan specified by the Distributee.

                                      -46-

                                  ARTICLE VIII
                                     TRUSTEE

      8.1   BASIC RESPONSIBILITIES OF THE TRUSTEE

      The Trustee shall have the following categories of responsibilities:

            (a)   With respect to Company Stock, the Company Stock Account, or
      an Exempt Loan, except as directed solely by the Administrator,

                  (1)   the Trustee shall not sell, acquire or dispose of 
            Company Stock or

                  (2)   enter into any Exempt Loan.

            Upon direction of the Administrator, up to one hundred percent
      (100%) of the Trust Fund may be invested in Company Stock.

            (b) With respect to the Other Investments Account and Directed
      Investment Account, the Trustee shall invest such Participant's Accounts
      as directed by the Administrator.

            (c) At the direction of the Administrator, the Trustee shall pay
      benefits required under the Plan to be paid to Participants, or, in the
      event of their death, to their Beneficiaries.

            (d) The Trustee shall maintain records of receipts and
      disbursements, and furnish to the Employer and/or Administrator for each
      Plan Year a written annual report according to Section 3.2 of this Trust
      Agreement.

            (e) If there shall be more than one Trustee, they shall act by a
      majority of their number, but may authorize one or more of them to sign
      papers on their behalf.

      8.2   VOTING COMPANY STOCK

      The Trustee shall vote all Company Stock held by it as part of the Plan
assets at such time and in such manner as the Administrator shall direct.
Provided, however, that if any agreement entered into by the Trustee, upon the
direction of the Administrator, provides for voting of any shares of Company
Stock pledged as security for any obligation of the Plan, then such shares of
Company Stock shall be voted in accordance with such agreement. If the
Administrator fails or refuses to give the Trustee timely instructions as to how
to vote any Company Stock held by the Trustee and which the Administrator
otherwise has the right to vote, the Trustee shall not vote such Company Stock
and shall consider the Administrator's failure or refusal to give timely
instructions as an exercise of the Administrator's rights and a directive to the
Trustee not to vote said Company Stock. The Trustee shall not vote Company Stock
when a Participant or Beneficiary, pursuant to this Section, fails to exercise a
right to vote Company Stock.

                                      -47-

      Notwithstanding the foregoing, if the Employer has a registration-type
class of securities, each Participant or Beneficiary shall be entitled, in lieu
of the Administrator, to direct the Trustee as to the manner in which the
Company Stock allocated to the Company Stock Account of such Participant or
Beneficiary is to be voted. If the Employer does not have a registration-type
class of securities, each Participant or Beneficiary in the Plan shall be
entitled, in lieu of the Administrator, to direct the Trustee as to the manner
in which voting rights on shares of Company Stock which are allocated to the
Company Stock Account of such Participant or Beneficiary are to be exercised
with respect to any corporate matter which involves the voting of such shares
with respect to the approval or disapproval of any corporate merger or
consolidation, recapitalization, reclassification, liquidation, dissolution,
sale of substantially all assets of a trade or business, or such similar
transaction as prescribed in Regulations. For purposes of this Section the term
"registration-type class of securities" means" (A) a class of securities
required to be registered under Section 12 of the Securities Exchange Act of
1934; and (B) a class of securities which would be required to be so registered
except for the exemption from registration provided in subsection (g)(2)(H) of
such Section 12.

      The Trustee shall notify each Participant or Beneficiary of each tender or
exchange offer and utilize its best efforts to distribute or cause to be
distributed to such Participant or Beneficiary in a timely manner all
information received by the Trustee as a recordholder of shares of Company Stock
in connection with any such tender or exchange offer. Each Participant or
Beneficiary shall have the right from time to time with respect to the shares of
Company stock allocated to his account, to instruct the Trustee in writing as to
the manner in which to respond to any tender or exchange offer which shall be
pending or which may be made in the future for all shares of Company Stock or
any portion thereof. A Participant's or Beneficiary's instructions shall remain
in force until superseded in writing by the Participant or Beneficiary. The
Trustee shall tender or exchange such shares of Company Stock as and to the
extent so instructed. Unless and until shares of Company Stock are tendered or
exchanged, the individual instructions received by the Trustee from Participant
or Beneficiaries shall be held in strict confidence by the Trustee and shall not
be divulged or released to any person, including, but not limited to officers or
Employees of the Employer, or of any other Participating Employer; provided,
however, that the Trustee shall advise the Employer, at any time upon request,
of the total number of shares not subject to instructions to tender or exchange.
The Trustee shall not make recommendations to Participants or Beneficiaries on
whether to instruct the Trustee to tender or exchange.

      The Trustee shall not vote, sell, convey or transfer any allocated shares
of Company Stock for which no directions are timely received from Participants
or Beneficiaries pursuant to the immediately preceding paragraph, and shares of
Company Stock held by the Trustee which are not allocated to Participants'
Company Stock Accounts shall be voted by the Trustee only in the manner directed
by the Administrator.

                                      -48-

                                   ARTICLE IX
                      AMENDMENT, TERMINATIONS, AND MERGERS

      9.1   AMENDMENT

      The Employer shall have the right at any time to amend the Plan. However,
no such amendment shall authorize or permit any part of the Trust Fund (other
than such part as is required to pay taxes and administration expenses) to be
used for or diverted to purposes other than for the exclusive benefit of the
Participants or their Beneficiaries or estates; no such amendment shall cause
any reduction in the amount credited to the account of any Participant or cause
or permit any portion of the Trust Fund to revert to or become the property of
the Employer; and no such amendment which affects the rights, duties or
responsibilities of the Trustee and Administrator may be made without the
Trustee's and Administrator's written consent. The Trustee shall not be required
to execute any such amendment unless the Trust provisions contained herein are
as part of the Plan and the amendment affects the duties of the Trustee
hereunder.

      In addition, no such amendment shall have the effect of terminating the
protections and rights set forth in Section 7.12, unless such termination shall
then be permitted under the applicable provisions of the Code and Regulations;
such a termination is currently expressly prohibited by Regulation
54.4975-11(a)(3)(ii).

      For the purposes of this Section, a Plan amendment which has the effect of
(1) eliminating or reducing an early retirement benefit or a retirement-type
subsidy, (2) eliminating an optional form of benefit (as provided in
Regulations) or (3) restricting, directly or indirectly, the benefit provided to
any Participant prior to the amendment shall be treated as reducing the amount
credited to the account of a Participant except that an amendment described in
clause (2) above (other than an amendment having an effect described in clause
(1) above) shall not be treated as reducing the amount credited to the account
of a Participant to the extent so provided in Regulations. Any Plan amendment
which modifies distribution options in a nondiscriminatory manner shall not be
treated as reducing the amount credited to the account of a Participant.

      9.2   TERMINATION

      The Employer shall have the right at any time to terminate the Plan by
delivering to the Trustee and Administrator written notice of such termination.
A complete discontinuance of the Employer Contributions to the Plan shall be
deemed to constitute a termination. Upon any termination (full or partial) or
complete discontinuance of contributions, all amounts credited to the affected
Participants' Accounts shall become 100% Vested and shall not thereafter be
subject to forfeiture and all unallocated amounts shall be allocated to the
accounts of all Participants in accordance with the provisions hereof. Upon such
termination of the Plan, the Employer, by written notice to the Trustee and
Administrator, may direct either:

            (a) complete distribution of the assets in the Trust Fund to the
      Participants, in cash or in kind, in a manner consistent with the
      requirements of Sections 7.5 and 7.6; or

                                      -49-

            (b) continuation of the Trust created by this agreement and the
      distribution of benefits at such time and in such manner as though the
      Plan had not been terminated.

      9.3   MERGER OR CONSOLIDATION

      This Plan may be merged or consolidated with, or its assets and/or
liabilities maybe transferred to any other Plan and Trust only if the benefits
which would be received by a Participant of this Plan, in the event of a
termination of the Plan immediately after such transfer, merger or
consolidation, are at least equal to the benefits the Participant would have
received if the Plan had terminated immediately before the transfer, merger or
consolidation.

                                      -50-

                                    ARTICLE X
                                  MISCELLANEOUS

      10.1  PARTICIPANT'S RIGHTS

      This Plan shall not be deemed to constitute a contract between the
Employer and any participant or to be a consideration or an inducement for the
employment of any Participant or Employee. Nothing contained in this Plan shall
be deemed to give any Participant or Employee the right to be retained in the
service of the Employer or to interfere with the right of the Employer to
discharge any Participant or Employee at any time regardless of the effect which
such discharge shall have upon him as a Participant of this Plan.

      10.2  ALIENATION

            (a) Subject to the exceptions provided below, no benefit which shall
      be payable out of the Trust Fund to any person (including a Participant or
      his Beneficiary) shall be subject in any manner to anticipation,
      alienation, sale, transfer, assignment, pledge, encumbrance, or charge,
      and any attempt to anticipate, alienate, sell, transfer, assign, pledge,
      encumber, or charge the same shall be void; and no such benefit shall be
      in any manner be liable for, or subject to, the debts, contracts,
      liabilities, engagements, or torts of any such person, nor shall it be
      subject to attachment or legal process for or against such person, and the
      same shall not be recognized by the Trustee, except to such extent as may
      be required by law.

            (b) This provision shall not apply to a "qualified domestic
      relations order" defined in Code Section 414(p), and those other domestic
      relations orders permitted to be so treated by the Administrator under the
      provisions of the Retirement Equity Act of 1984. The Administrator shall
      establish a written procedure to determine the qualified status of
      domestic relations orders and to administer distributions under such
      qualified orders. Further, to the extent provided under a "qualified
      domestic relations order", a Former spouse of a Participant shall be
      treated as the spouse or surviving spouse for all purposes under the Plan.

      10.3  CONSTRUCTION OF PLAN

      This Plan shall be construed and enforced according to the Act and the
laws of the State of Delaware, other than its laws respecting choice of law, to
the extent not preempted by the Act.

      10.4  GENDER AND NUMBER

      Wherever any words are used herein in the masculine, feminine or neuter
gender, they shall be construed as though they were also used in another gender
in all cases where they would so apply, and whenever any words are used herein
in the singular or plural form, they shall be construed as though they were also
used in the other form in all cases where they would so apply.

                                      -51-

      10.5  LEGAL ACTION

      In the event any claim, suit, or proceeding is brought regarding the Trust
and/or Plan established hereunder to which the Trustee or the Administrator may
be a party, and such claim suit, or proceeding is resolved in favor of the
Trustee or Administrator, they shall be entitled to be reimbursed from the Trust
Fund for any and all costs, attorney's fees, and other expenses pertaining
thereto incurred by them for which they shall have become liable.

      10.6  PROHIBITION AGAINST DIVERSION OF FUNDS

            (a) Except as provided below and otherwise specifically permitted by
      law, it shall be impossible by operation of the Plan or of the Trust, by
      termination of either, by power or revocation or amendment, by the
      happening of any contingency, by collateral arrangement or by any other
      means, for any part of the corpus or income of any trust fund maintained
      pursuant to the Plan or any funds contributed thereto to be used for, or
      diverted to, purposes other than the exclusive benefit of Participants,
      Retired Participants, or their Beneficiaries.

            (b) In the event the Employer shall make an excessive contribution
      under a mistake of fact pursuant to Section 403(c)(2)(A) of the Act, the
      Employer may demand repayment of such excessive contribution at any time
      within one (1) year following the time of payment and the Trustees shall
      return such amount to the Employer within the one (1) year period.
      Earnings of the Plan attributable to the excess contributions may not be
      returned to the Employer but any losses attributable thereto must reduce
      the amount so returned.

      10.7  BONDING

      Every Fiduciary, except a bank or an insurance company, unless exempted by
the Act and regulations thereunder, shall be bonded in an amount not less than
10% of the amount of the funds such Fiduciary handles; provided, however, that
the minimum bond shall be $1,000 and the maximum bond, $500,000. The amount of
funds handled shall be determined at the beginning of each Plan Year by the
amount of funds handled by such person, group, or class to be covered and their
predecessors, if any, during the preceding Plan Year, or if there is no
preceding Plan Year, then by the amount of the funds to be handled during the
then current year. The bond shall provide protection to the Plan against any
loss by reason of acts of fraud or dishonesty by the Fiduciary alone or in
connivance with others. The surety shall be a corporate surety company (as such
term is used in Section 412(a)(2) of the Act), and the bond shall be in a form
approved by the Secretary of Labor. Notwithstanding anything in the Plan to the
contrary, the cost of such bonds shall be an expense of and may, at the election
of the Administrator, be paid from the Trust Fund or by the Employer.

      10.8  RECEIPT AND RELEASE FOR PAYMENTS

      Any payment to any Participant, his legal representative, Beneficiary, or
to any guardian or committee appointed for such Participant or Beneficiary in
accordance with the provisions of the Plan, shall, to the extent thereof, be in
full satisfaction of all claims hereunder against the Trustee and the Employer,
either of whom may require such Participant, legal representative, Beneficiary,

                                      -52-

guardian or committee, as a condition precedent to such payment, to execute a
receipt and release thereof in such form as shall be determined by the Trustee
or Employer.

      10.9  ACTION BY THE EMPLOYER

      Whenever the Employer under the terms of the Plan is permitted or required
to do or perform any act or matter or thing, it shall be done and performed by a
person duly authorized by its legally constituted authority.

      10.10 NAMED FIDUCIARIES AND ALLOCATION OF RESPONSIBILITY

      The "named Fiduciaries" of this Plan are the Employer and the
Administrator. The named Fiduciaries shall have only those specific powers,
duties, responsibilities, and obligations as are specifically given them under
the Plan. In general, the Employer shall have the sole responsibility for making
the contributions provided for under Section 4.1; and shall have the sole
authority to appoint and remove the Trustee and the Administrator; to formulate
the Plan's "funding policy and method"; and to amend or terminate, in whole or
in part, the Plan. The Administrator shall have the sole responsibility for the
administration of the Plan, which responsibility is specifically described in
the Plan, including the acquisition, holding and/or disposition of Company Stock
and the entering into any Exempt Loans. The Administrator shall also have the
sole responsibility of management of the assets of the Other Investments Account
and Directed Investment Account held under the Trust, except those assets in
such accounts, the management of which has been assigned to an Investment
Manager, who shall be solely responsible for the management of the assets
assigned to it, all as specifically provided in the Plan.

      10.11 HEADINGS

      The headings and subheadings of this Plan have been inserted for
convenience of reference and are to be ignored in any construction of the
provisions hereof.

      10.12 APPROVAL BY INTERNAL REVENUE SERVICE

            (a) Notwithstanding anything herein to the contrary, contributions
      to this Plan are conditioned upon the initial qualification of the Plan
      under Code Section 401. If the Plan receives an adverse determination with
      respect to its initial qualification, then the Plan may return such
      contributions to the Employer within one year after such determination,
      provided the application for the determination is made by the time
      prescribed by law for filing the Employer's return for the taxable year in
      which the Plan was adopted, or such later date as the Secretary of the
      Treasury may prescribe.

            (b) Notwithstanding any provisions to the contrary, except Sections
      3.6 and 4.3(d), any contribution by the Employer to the Trust Fund is
      conditioned upon the deductibility of the contribution by the Employer
      under the Code and, to the extent any such deduction is disallowed, the
      Employer may, within one (1) year following the disallowance of the
      deduction, demand repayment of such disallowed contribution and the
      trustee shall

                                      -53-

      return such contribution within one (1) year following the disallowance of
      the deduction, demand repayment of such disallowed contribution and the
      Trustee shall return such contribution within one (1) year following the
      disallowance. Earnings of the Plan attributable to the excess contribution
      may not be returned to the Employer, but any losses attributable thereto
      must reduce the amount so returned.

      10.13 UNIFORMITY

      All provisions of this Plan shall be interpreted and applied in a uniform,
nondiscriminatory manner.

      10.14 SECURITIES AND EXCHANGE COMMISSION APPROVAL

      The Company may request an interpretative letter from the Securities and
Exchange Commission stating that the transfer of Company Stock contemplated
hereunder does not involve transactions requiring a registration of such Company
Stock under the Securities Act of 1933. In the event that a favorable
interpretative letter is not obtained, the Employer reserves the right to amend
the Plan and Trust retroactively to their Effective Dates in order to obtain a
favorable interpretative letter or to terminate the Plan.

      10.15 INDEMNIFICATION

      Neither the Employer, any of its officers or directors, nor the
Administrator shall be personally liable for any action or inaction with respect
to any duty or responsibility imposed upon such person by the terms of the Plan,
unless such action or inaction is judicially determined to be a breach of that
person's fiduciary responsibility with respect to the Plan under any applicable
law. The Employer may indemnify or purchase insurance to underwrite indemnity
for the Administrator and/or the Employer's board of directors against any
personal liability or expense except for their own gross negligence.

      10.16 CONTROLLING LAW

      All legal questions pertaining to the Plan, all construction and all
Regulations shall be determined in accordance with the laws of the State of
Delaware and the United States. All contributions shall be deemed to have been
made under such laws. Notwithstanding anything in this Agreement to the
contrary, the effective dates provided for herein for the application of any
Code Section to this Plan shall be extended in accordance with any act of
Congress or any effective Regulation, Ruling or other measure of like import.

                                      -54-

                                   ARTICLE XI
                             PARTICIPATING EMPLOYERS

      11.1  ADOPTION BY OTHER EMPLOYERS

      Notwithstanding anything herein to the contrary, with the consent of the
Employer and Trustee, any other corporation or entity, whether an affiliate or
subsidiary or not, may adopt this Plan and all of the provisions hereof, and
participate herein and be known as a Participating Employer, by a properly
executed document evidencing said intent and will of such Participating
Employer.

      11.2  REQUIREMENTS OF PARTICIPATING EMPLOYERS

            (a) Each such Participating Employer shall be required to use the
      same Trustee as provided in this Plan.

            (b) The Trustee, unless directed otherwise by the Administrator,
      shall commingle and hold as one Trust Fund all contributions made by
      Participating Employers.

            (c) The transfer of any Participant from or to an Employer
      participating in this Plan, whether he be an Employee of the Employer or a
      Participating Employer, shall not affect such Participant's rights under
      the Plan, and all amounts credited to such Participant's Account as well
      as his accumulated service time with the transferor or predecessor, and
      his length of participation in the Plan, shall continue to his credit.

            (d) All rights and values forfeited by termination of employment
      shall inure only to the benefit of the Employee-Participants of the
      Participating Employer by which the forfeiting Participant was employed,
      except if the Forfeiture is for an Employee whose Employer is a member of
      an affiliated or controlled group, then said Forfeiture shall be
      allocated, based on Compensation to all Participant Accounts of
      Participating Employers who are members of the affiliated or controlled
      group. Should an Employee of one ("First") Employer be transferred to an
      associated ("Second") Employer (the Employer, an affiliate or subsidiary),
      such transfer shall not cause his Account balance (generated while an
      Employee of "First" Employer) in any manner or by any amount to be
      forfeited. Such Employee's Participant Account balance for all purposes of
      the Plan, including length of service, shall be considered as though he
      had always been employed by the "Second" Employer and as such had received
      contributions, forfeitures, earnings of losses, and appre ciation or
      depreciation in value of assets totaling amount so transferred.

            (e) Any expenses of the Trust which are to be paid by the Employer
      or borne by the Trust Fund shall be paid by each Participating Employer in
      the same proportion that the total amount standing to the credit of all
      Participants employed by such Employer bears to the total standing to the
      credit of all Participants.

                                      -55-

      11.3  DESIGNATION OF AGENT

      Each Participating Employer shall be deemed to be a part of this Plan;
provided, however, that with respect to all of its relations with the Trustee
and Administrator for the purpose of this Plan, each Participating Employer
shall be deemed to have designated irrevocably the Employer as its agent. Unless
the context of the Plan clearly indicates the contrary, the word "Employer"
shall be deemed to include each Participating Employer as related to its
adoption of the Plan.

      11.4  EMPLOYEE TRANSFERS

      It is anticipated that an Employee may be transferred between
Participating Employers, and in the event of any such transfer, the Employee
involved shall carry with him his accumulated service and eligibility. No such
transfer shall effect a termination of employment hereunder, and the
Participating Employer to which the Employee is transferred shall thereupon
become obligated hereunder with respect to such Employee in the same manner as
was the Participating Employer from whom the Employee was transferred.

      11.5  PARTICIPATING EMPLOYER'S CONTRIBUTION

      Any contribution or Forfeiture subject to allocation during each Plan Year
shall be allocated among all Participants of all Participating Employers in
accordance with the provisions of this Plan. On the basis of the information
furnished by the Administrator, the Trustee shall keep separate books and
records concerning the affairs of each Participating Employer hereunder and as
to the accounts and credits of the Employees of each Participating Employer. The
Trustee may, but need not, register Contracts so as to evidence that a
particular Participating Employer is the interested Employer hereunder, but in
the event of an Employee transfer from one Participating Employer to another,
the employing Employer shall immediately notify the Trustee thereof.

      11.6  AMENDMENT

      Amendment of this Plan by the Employer at any time when there shall be a
Participating Employer hereunder shall only be by the written action of each and
every Participating Employer and with the consent of the Trustee where such
consent is necessary in accordance with the terms of this Plan.

      11.7  DISCONTINUANCE OF PARTICIPATION

      Any Participating Employer shall be permitted to discontinue or revoke its
participation in the Plan. At the time of any such discontinuance or revocation,
satisfactory evidence thereof and of any applicable conditions imposed shall be
delivered to the Trustee. The Trustee shall thereafter transfer, deliver and
assign Trust Fund assets allocable to the Participants of such Participating
Employer or to such new Trustee as shall have been designated by such
Participating Employer, in the event that it has established a separate pension
plan for its Employees. If no successor is designated, the Trustee shall retain
such assets for the Employees of said Participating Employer pursuant to the
provisions of Article VII hereof. In no such event shall any part of the corpus
or

                                      -56-

income of the Trust as it relates to such Participating Employer be used for or
diverted for purposes other than for the exclusive benefit of the Employees of
such Participating Employer.

      11.8  ADMINISTRATOR'S AUTHORITY

      The Administrator shall have authority to make any and all necessary rules
or regulations, binding upon all Participating Employers and all Participants,
to effectuate the purpose of this Article.

      11.9  PARTICIPATING EMPLOYER CONTRIBUTION FOR AFFILIATE

      If any Participating Employer is prevented in whole or in part from making
a contribution to the Trust Fund which it would otherwise have made under the
Plan by reason of having no current or accumulated earnings or profits, or
because such earnings or profits are less than the contribution which it would
otherwise have made, then, pursuant to Code Section 404(a)(3)(B), so much of the
contribution which such Participating Employer was so prevented from making may
be made, for the benefit of the participating employees of such Participating
Employer, by the other Participating Employers who are members of the same
affiliated group within the meaning of Code Section 1504 to the extent of their
current or accumulated earnings or profits, except that such contribution by
each such other Participating Employer shall be limited to the proportion of its
total current and accumulated earnings or profits remaining after adjustment for
its contribution to the Plan made without regard to this paragraph which the
total prevented contribution bears to the total current and accumulated earnings
or profits of all the Participating Employers remaining after adjustment for all
contributions made to the Plan without regard to this paragraph.

      A Participating Employer on behalf of whose employees a contribution is
made under this paragraph shall not reimburse the contributing Participating
Employers.

      This Agreement may be executed in two or more counterparts which together
shall constitute a single agreement.

                                      -57-

                                   ARTICLE XII
                                TOP-HEAVY STATUS

      12.1  ARTICLE CONTROLS

      Any Plan provisions to the contrary notwithstanding, the provisions of
this Article shall control to the extent required to cause the Plan to comply
with the requirements imposed under Code Section 416.

      12.2  DEFINITIONS

      For purposes of this Article, the following terms and phrases shall have
these respective meanings:

            (a) ACCOUNT BALANCE: As of any Valuation Date, the aggregate amount
      credited to an individual's account or accounts under a qualified defined
      contribution plan maintained by the Employer or an Affiliated Employer
      (excluding employee contributions which were deductible within the meaning
      of section 219 of the Code and rollover or transfer contributions made
      after December 31, 1983 by or on behalf of such individual to such plan
      from another qualified plan sponsored by an entity other than the Employer
      or an Affiliated Employer), increased by (1) the aggregate distributions
      made to such individual from such plan during a five-year period ending on
      the Determination Date and (2) the amount of any contributions due as of
      the Determination Date immediately following such Valuation Date.

            (b) ACCRUED BENEFIT: As of any Valuation Date, the present value
      (computed on the basis of the Assumptions) of the cumulative accrued
      benefit (excluding the portion thereof which is attributable to employee
      contributions which were deductible pursuant to section 219 of the Code,
      to rollover or transfer contributions made after December 31, 1983 by or
      on behalf of such individual to such plan from another qualified plan
      sponsored by an entity other than the Employer or an Affiliated Employer,
      to proportional subsidies or to ancillary benefits) of an individual under
      a qualified defined benefit plan maintained by the Employer or an
      Affiliated Employer increased by (1) the aggregate distributions made to
      such individual from such plan during a five-year period ending on the
      Determination Date and (2) the estimated benefit accrued by such
      individual between such Valuation Date and the Determination Date
      immediately following such Valuation Date. Solely for the purpose of
      determining top-heavy status, the Accrued Benefit of an individual shall
      be determined under (1) the method, if any, that uniformly applies for
      accrual purposes under all qualified defined benefit plans maintained by
      the Employer or an Affiliated Employer, or (2) if there is no such method,
      as if such benefit accrued not more rapidly than under the slowest accrual
      rate permitted under section 411(b)(1)(C) of the Code.

            (c) AGGREGATION GROUP: The group of qualified plans maintained by
      the Employer and each Affiliated Employer consisting of (1) each plan in
      which a Key Employee participates and each other plan which enables a plan
      in which a Key Employee participates to meet the requirements of sections
      401(a)(4) or 410 of the Code, or (2) each

                                      -58-

      plan in which a Key Employee participates, each other plan which enables a
      plan in which a Key Employee participates to meet the requirements of
      sections 401(a)(4) or 410 of the Code and any other plan which the
      Employer elects to include as a part of such group; provided, however,
      that the Employer may not elect to include a plan in such group if its
      inclusion would cause the group to fail to meet the requirements of
      sections 401(a)(4) or 410 of the Code.

            (d) ASSUMPTIONS: The interest rate and mortality assumptions
      specified for top-heavy status determination purposes in any defined
      benefit plan included in the Aggregation Group including the Plan.

            (e) DETERMINATION DATE: For the first Plan Year of any plan, the
      last day of such Plan Year and for each subsequent Plan Year of such plan,
      the last day of the preceding Plan Year.

            (f)   KEY EMPLOYEE:  A "key employee" as defined in section 416(i)
      of the Code and the Treasury Regulations thereunder.

            (g)   PLAN YEAR:  With respect to any plan, the annual accounting
      period used by such plan for annual reporting purposes.

            (h) REMUNERATION: Compensation within the meaning of section
      415(c)(3) of the Code, as limited by section 401(a)(17) of the Code for
      Plan Years beginning after December 31, 1988.

            (i) VALUATION DATE: With respect to any Plan Year of any defined
      contribution plan, the most recent date within the twelve-month period
      ending on a Determination Date as of which the trust fund established
      under such plan was valued and the net income (or loss) thereof allocated
      to participants' accounts. With respect to any Plan Year of any defined
      benefit plan, the most recent date within a twelve-month period ending on
      a Determination Date as of which the plan assets were valued for purposes
      of computing plan costs for purposes of the requirements imposed under
      section 412 of the Code.

      12.3  TOP-HEAVY STATUS

            (a) The Plan shall be deemed to be top-heavy for a Plan Year, if, as
      of the Determination Date for such Plan Year, (1) the sum of Account
      Balances of Participants who are Key Employees exceeds 60% of the sum of
      Account Balances of all Participants unless an Aggregation Group including
      the Plan is not top-heavy or (2) an Aggregation Group including the Plan
      is top-heavy. An Aggregation Group shall be deemed to be top-heavy as of a
      Determination Date if the sum (computed in accordance with section
      416(g)(2)(B) of the Code and the Treasury Regulations promulgated
      thereunder) of (1) the Account Balances of Key Employees under all defined
      contribution plans included in the Aggregation Group and (2) the Accrued
      Benefits of Key Employees under all defined benefit plans included in the
      Aggregation Group exceeds 60% of the sum of the Account Balances and the
      Accrued

                                      -59-

      Benefits of all individuals under such plans. Notwithstanding the
      foregoing, the Account Balances and Accrued Benefits of individuals who
      are not Key Employees in any Plan Year but who were Key Employees in any
      prior Plan Year shall not be considered in determining the top-heavy
      status of the Plan for such Plan Year. Further, notwithstanding the
      foregoing, the Account Balances and Accrued Benefits of individuals who
      have not performed services for the Employer at any time during the
      five-year period ending on the applicable Determination Date shall not be
      considered.

      12.4  TERMINATION OF TOP-HEAVY STATUS

      If the Plan has been deemed to be top-heavy for one or more Plan Years and
thereafter ceases to be top-heavy, the provisions of this Article shall cease to
apply to the Plan effective as of the Determination Date on which it is
determined to no longer be top-heavy.

      12.5  EFFECT OF ARTICLE

      Notwithstanding anything contained herein to the contrary, the provisions
of this Article shall automatically become inoperative and of no effect to the
extent not required by the Code or the Act.
