     and (iii) any salary reduction amounts elected by such Employee for the
     purchase of benefits pursuant to a cafeteria plan (within the meaning of

     that except for purposes of determining whether an Employee is a Highly
     Compensated Employee or a Key Employee (as defined in Section 9.1(c)), the
     Compensation of an Employee taken into account under the Plan for any Plan
     Year shall not exceed $150,000 (as adjusted to take into account any cost-

     Code).

          (g) "Covered Employee" means any Employee other than (i) a member of a

          (i) "Employer" shall include the Company and any other incorporated or

          preceding Plan Year was at any time a 5 percent owner (as defined in
          Section 416(i)(1) of the Code) of an Employer or Affiliated Company;
          or

              (2)  any Employee who during the preceding Plan Year received

          any cost-of-

<PAGE>
 
          living increases authorized pursuant to Section 414(q)(1) of the Code)
          and, if the Company so elects, who is in the group consisting of the
          top 20% (when ranked on the basis of Compensation received during such
          preceding year) of all Employees, except those excluded pursuant to
          Section 414(q)(5) of the Code.

     Solely for purposes of this definition, (i) an employee of an Affiliated
     Company shall be deemed to be an Employee, (ii) compensation received from
     an Affiliated Company shall be deemed to be Compensation, and (iii) a
     nonresident alien who receives no earned income from an Employer or
     Affiliated Company which constitutes income from sources within the United
     States shall not be considered an Employee.

          (m) "Hour of Service" means an hour for which an Employee is directly
     or indirectly compensated or entitled to compensation (including back pay,
     regardless of mitigation of damages) by an Employer for the performance of
     duties for an Employer or for reasons (such as vacation, sickness or
     disability) other than the performance of duties for an Employer.  An
     Employee will be credited with eight Hours of Service per day for any
     customary work period during which such Employee is on leave of absence
     authorized by his or her Employer.  Leaves of absence shall be granted by
     an Employer to its Employees on a uniform, nondiscriminatory basis.  In no
     event shall more than 501 Hours of Service be credited on account of any
     single continuous period during which the individual performs no duties.
     An Employee's Hours of Service shall be credited to the appropriate Plan
     Years determined in accordance with the provisions of Section 2530.200b-
     2(b) and (c) of the Department of Labor Regulations, which are incorporated
     herein by this reference.  In determining Hours of Service for the purposes
     of this Plan, periods of employment by an Affiliated Company and periods of
     employment as a leased employee (within the meaning of Section 414(n) of
     the Code) of an Employer or Affiliated Company shall be deemed to be
     periods of employment by an Employer.

     Solely for purposes of determining whether an Employee incurs a One Year
     Break in Service, Hours of Service shall also include hours (not to exceed
     501 such hours) that would normally be credited to an Employee but for an
     absence from work due to the pregnancy of the Employee, the birth of a
     child of the Employee, the placement of a child with the Employee in
     connection with the adoption of such child by such Employee, or caring for
     such child for a period beginning immediately following such birth or
     placement. If the number of hours described in the preceding sentence
     cannot be determined, an Employee shall be credited with eight Hours of
     Service per normal work day of such absence. Such Hours of Service shall be
     credited only in the computation period in which such absence from work
     begins if such Employee would be prevented from incurring a One Year Break
     in Service in such year due to the crediting of such hours, or in any other
     case, in the immediately following computation period.

          (n) "Investment Fund" means any fund authorized for the investment of
     Trust assets pursuant to Section 4.2.

                                      -3-

     Participant attains the age of 65 years.

                                  ARTICLE III.

                   CONTRIBUTIONS, LIMITATIONS AND FORFEITURES

     Section 3.1  Matching Contributions.  For each pay period an Employer
shall make to the Plan for each Participant in its employ who elects to have the
Maximum Basic Deferral Contribution made to the Titan 401(k) Plan on his or her
behalf for such pay period a Matching Contribution equal to 200 percent of such
Maximum Basic Deferral Contribution.  Contributions made by an Employer to the
Plan for a Plan Year shall be paid to the Trustee as soon as practicable, but no
later than the time prescribed by law, including extensions thereof, for the
filing of the Employer's federal income tax return for such year.

     Section 3.2  Crediting of Contributions.  The Committee shall establish
and maintain a Matching Account for each Participant.  All Matching
Contributions made for a Participant shall be credited to such Participant's
Matching Account.

     Section 3.3  Return of Matching Contributions.  Contributions to this Plan
are conditioned upon the initial qualification of this Plan under Section 401(a)
of the Code and upon being currently deductible under Section 404 of the Code.
Any provision of this Plan to the contrary notwithstanding, upon an Employer's
request, any such contribution or portion thereof made to this Plan by such
Employer which (i) was made under a mistake of fact which is subsequently
discovered, (ii) is disallowed as a deduction under Section 404 of the Code, or
(iii) was made prior to the denial by the Internal Revenue Service of the
initial qualification of this Plan under Section 401(a) of the Code, shall be
returned to such Employer to the extent not previously distributed to
Participants or their beneficiaries; provided, however, that the amounts
returnable to an Employer pursuant to this Section shall be reduced by any Trust
losses allocable thereto and shall be returned to such Employer only if such
return is made within one year after the mistaken payment of the contribution,
the date of the disallowance of the deduction, or the date of the denial of the
initial qualification of the Plan, as the case may be.  Except as provided in
this Section, no contribution made by an Employer pursuant to this Plan shall
ever revert to or be recoverable by any Employer.

     Section 3.4  Limitations on Contributions.

          (a) Any provision of this Plan to the contrary notwithstanding, if
     for any Plan Year the contribution percentage for the group of Highly
     Compensated Employees eligible to receive an allocation of Matching
     Contributions or Discretionary Matching Contributions under the Titan
     401(k) Plan for such Plan Year or to make After-Tax Contributions to the
     Titan 401(k) Plan for such Plan Year fails to satisfy one of the following
     tests:

              (1) the contribution percentage for said group of Highly
          Compensated Employees is not more than 1.25 times the contribution
          percentage for the preceding Plan Year for all Non-Highly Compensated
          Employees eligible for the preceding Plan Year to receive an
          allocation of Matching Contributions or 

                                      -6-
<PAGE>
 
          Discretionary Matching Contributions under the Titan 401(k) Plan or to
          make After-Tax Contributions to the Titan 401(k) Plan, or

              (2) the excess of the contribution percentage for said group of
          Highly Compensated Employees over the contribution percentage for the
          preceding Plan Year for all Non-Highly Compensated Employees eligible
          for the preceding Plan Year to receive an allocation of Matching
          Contributions or Discretionary Matching Contributions under the Titan
          401(k) Plan or to make After-Tax Contributions to the Titan 401(k)
          Plan is not more than two percentage points, and the contribution
          percentage for said group of Highly Compensated Employees is not more
          than two times the contribution percentage for the preceding Plan Year
          for all Non-Highly Compensated Employees eligible for the preceding
          Plan Year to receive an allocation of Matching Contributions or
          Discretionary Matching Contributions under the Titan 401(k) Plan or to
          make After-Tax Contributions to the Titan 401(k) Plan,

     then the contribution percentage of Participants who are members of said
     group of Highly Compensated Employees shall be reduced by reducing the
     contribution percentages of the Highly Compensated Employees with the
     largest individual contribution percentages to the largest uniform
     contribution percentage (commencing with the Highly Compensated Employee
     with the largest contribution percentage and reducing his or her
     contribution percentage to the extent necessary to satisfy one of the above
     tests or to lower such contribution percentage to the contribution
     percentage of the Highly Compensated Employee with the next highest
     contribution percentage, and repeating this process as necessary) that
     permits the contribution percentage for said group of Highly Compensated
     Employees to satisfy one of said tests.  For purposes of this subsection
     (a), the term "contribution percentage" for a specified group of Employees
     for a Plan Year means the average of the ratios (calculated separately for
     each Employee in such group and after application of the reduction and
     forfeiture provisions of subsections (a) and (b) of Section 3.6 of the
     Titan 401(k) Plan) of (i) the aggregate amount of Matching Contributions
     made to this Plan and Discretionary Matching Contributions and After-Tax
     Contributions made to the Titan 401(k) Plan by or for such Employee for
     that year and, at the election of the Committee, all or a portion of the
     Deferral Contributions made on behalf of such Employee for that year which
     are not in excess of the amount of such contributions that are permitted to
     be taken into account under Sections 401(k) and (m) of the Code and the
     regulations thereunder, to (ii) the amount of such Employee's Compensation
     for that year or, in the Committee's discretion, only for such portion of
     that year during which the Employee was eligible to participate in the
     Plan.  If two or more plans to which matching contributions or employee
     after-tax contributions are made are considered as one plan for purposes of
     Section 410(b) of the Code (other than for purposes of the average benefit
     percentage test), such plans shall be treated as one plan for purposes of
     determining the contribution percentages for this subsection (a).  If a
     Highly Compensated Employee is a participant in two or more plans to which
     matching contributions or employee after-tax contributions are made, then
     for purposes of determining the contribution ratio of such 

                                      -7-

     Employee, all such plans (other than those that may not be permissively
     aggregated) shall be treated as one plan.

          (b) The aggregate amount of any Matching Contributions made to this
     Plan and Discretionary Matching Contributions and After-Tax Contributions
     made to the Titan 401(k) Plan by or for Participants which cannot be
     credited to Participants' Accounts for a Plan Year because of the
     limitation contained in subsection (a) of this Section (along with any
     income allocable to such contributions for such Plan Year, but not for the
     gap period following such Plan Year), calculated by adding together the
     dollar amount of excess aggregate contributions determined in subsection
     (a) of this Section for each affected Highly Compensated Employee, shall be
     forfeited if forfeitable, but if not forfeitable, distributed to such
     Participants no later than 2 1/2 months after the end of such year with the
     amount to be distributed to particular Participants to be determined on the
     basis of the amount of Matching Contributions made to this Plan and the
     amount of Discretionary Matching Contributions and After-Tax Contributions
     made to the Titan 401(k) Plan by or for each such Participant (commencing
     with the Highly Compensated Employee with the largest total amount of
     Matching Contributions and Discretionary Matching Contributions and After-
     Tax Contributions under the Titan 401(k) Plan for such Plan Year and
     reducing first his or her After-Tax Contributions made to the Titan 401(k)
     Plan, then Discretionary Matching Contributions made to the Titan 401(k)
     Plan and then, if necessary, Matching Contributions made to this Plan to
     the extent necessary to distribute such aggregate amount or to lower such
     amount to the total amount of Matching Contributions and Discretionary
     Matching Contributions and After-Tax Contributions under the Titan 401(k)
     Plan of the Highly Compensated Employee with the next highest amount of
     such contributions, and repeating this process as necessary).  The income
     allocable to any such excess aggregate contributions for a Participant for
     a Plan Year shall be determined by multiplying the amount of income
     allocable to such Participant's Matching Account or Discretionary Matching
     Account or After-Tax Account under the Titan 401(k) Plan, whichever is
     applicable, for such year by a fraction, the numerator of which is the
     amount of the excess aggregate contributions for such year and the
     denominator of which is the sum of the amount credited to such
     Participant's Matching Account or Discretionary Matching Account or After-
     Tax Account under the Titan 401(k) Plan, whichever is applicable, as of the
     beginning of such year plus the amount of the Matching Contributions or
     Discretionary Matching Contributions or After-Tax Contributions to the
     Titan 401(k) Plan, whichever is applicable, made by or for such Participant
     for such year.

          (c) Any provision of this Plan to the contrary notwithstanding, in
     addition to the above limitations of this Section, the sum of the actual
     deferral percentage and the contribution percentage for the group of Highly
     Compensated Employees as determined pursuant to and after any reduction in
     such percentages required by subsection (a) of this Section and subsections
     (a) and (d) of Section 3.6 of the Titan 401(k) Plan shall not exceed the
     "aggregate limit."  The "aggregate limit" shall be equal to the greater of:

                                      -8-
<PAGE>
 
              (1) the sum of:  (i) 1.25 times the greater of the relevant
          actual deferral percentage or the relevant contribution percentage,
          and (ii) two percentage points plus the lesser of the relevant actual
          deferral percentage or the relevant contribution percentage, provided
          that the amount in this clause (ii) shall not exceed two times the
          lesser of the relevant actual deferral percentage or the relevant
          contribution percentage; or

              (2) the sum of:  (i) 1.25 times the lesser of the relevant
          actual deferral percentage or the relevant contribution percentage,
          and (ii) two percentage points plus the greater of the relevant actual
          deferral percentage or the relevant contribution percentage, provided
          that the amount in this clause (ii) shall not exceed two times the
          greater of the relevant actual deferral percentage or the relevant
          contribution percentage.

     The "relevant actual deferral percentage" means the actual deferral
     percentage determined for the preceding Plan Year pursuant to subsection
     (a) of Section 3.6 of the Titan 401(k) Plan for the group of Non-Highly
     Compensated Employees eligible during the preceding Plan Year to have
     Deferral Contributions made to the Titan 401(k) Plan. The "relevant
     contribution percentage" means the contribution percentage determined for
     the preceding Plan Year pursuant to subsection (a) of this Section and
     Section 3.6(c) of the Titan 401(k) Plan for the group of Non-Highly
     Compensated Employees eligible for the preceding Plan Year to receive an
     allocation of Matching Contributions or Discretionary Matching
     Contributions under the Titan 401(k) Plan or eligible to make After-Tax
     Contributions to the Titan 401(k) Plan.  In the event that the aggregate
     limit is exceeded in any year, then the actual deferral percentage and/or
     contribution percentage for Participants who are members of the group of
     Highly Compensated Employees shall be reduced by reducing first any After-
     Tax Contributions made to the Titan 401(k) Plan, then any Deferral
     Contributions made to the Titan 401(k) Plan, then any Discretionary
     Matching Contributions made to the Titan 401(k) Plan and finally any
     Matching Contributions made to this Plan for such Year by, for or on behalf
     of the Highly Compensated Employees with the largest individual actual
     deferral percentages and/or contribution percentages to the largest uniform
     actual deferral percentage and/or contribution percentage (proceeding in
     the manner prescribed in subsections (a) and (c) of Section 3.6 of the
     Titan 401(k) Plan and subsection (a) of this Section) that permits the sum
     of the actual deferral percentage and contribution percentage for said
     group of Highly Compensated Employees to satisfy the above restrictions.
     The provisions of Section 3.6(b) and (d) of the Titan 401(k) Plan and
     subsection (b) of this Section shall apply with respect to any After-Tax
     Contributions, Deferral Contributions and Discretionary Matching
     Contributions under the Titan 401(k) Plan and Matching Contributions which
     cannot be credited to After-Tax Accounts, Deferral Accounts and
     Discretionary Matching Accounts under the Titan 401(k) Plan and Matching
     Accounts under the Titan Matching Plan, as the case may be, because of the
     limitation contained in this subsection (c).

          (d) If any portion of a Deferral Contribution is distributed to a
     Participant pursuant to Section 3.6(b) of the Titan 401(k) Plan, any
     portion of a Matching Contribution (along with any income allocable
     thereto) made to this Plan for such Participant that matches the
     distributed Deferral Contribution shall be forfeited.  If any portion of a
     Deferral Contribution under the Titan 401(k) Plan is distributed to a
     Participant pursuant to Section 3.1(e), any portion of a Matching
     Contribution (along with any income allocable thereto) made to this Plan
     for such Participant that matches the distributed Deferral Contribution
     shall be forfeited.

          (e) Any provision of this Section to the contrary notwithstanding, the
     Company may elect, in accordance with Section 401(k) and (m) of the Code
     and any regulations or other Treasury pronouncements pertaining thereto, to
     use data for the current Plan Year, rather than the preceding Plan Year, in
     determining the actual deferral percentage and the contribution percentage
     required by this Section for Non-Highly Compensated Employees.

     Section 3.5  Application and Allocation of Forfeitures.  All amounts
forfeited during a Plan Year shall first be applied to restore any forfeited
Matching Account required to be restored pursuant to Sections 6.5 and 6.7, and
any forfeitures in excess of the amount needed to restore any such Matching
Account shall be allocated among and credited to the Matching Accounts of (A)
those Participants who both (i) were employed by (or on authorized leave of
absence from) an Employer as a Covered Employee on the last day of such Plan
Year and (ii) completed at least 500 Hours of Service during such Plan Year and
(B) those Participants whose Retirement, Permanent Disability or death occurred
while employed by (or on authorized leave of absence from) an Employer as a
Covered Employee during such Plan Year, in the proportion that the Compensation
for each such Participant while both a Participant and a Covered Employee during
that year bears to the Compensation of all such Participants while both
Participants and Covered Employees during that year.


                                  ARTICLE IV.

                     TRUST FUND, INVESTMENTS AND VALUATIONS

     Section 4.1  Trust and Trustee.  All of the contributions paid to the
Trustee pursuant to this Plan, together with the income therefrom and the
increments thereof, shall be held in trust by the Trustee under the terms and
provisions of the separate trust agreement between the Trustee and the Company,
a copy of which is attached hereto and incorporated herein by this reference for
all purposes, establishing a trust fund known as the TITAN MATCHING TRUST for
the exclusive benefit of the Participants and their beneficiaries.

     Section 4.2  Trust Investment Options.  All amounts credited to a
Participant's Matching Account shall be invested in one or more of the
Investment Funds, at the direction of such Participant in accordance with the
provisions of this Section.  The assets of the Trust shall be divided into such
number and kind of separate and distinct Investment Funds as the Committee 

                                      -10-
<PAGE>
 
in its absolute discretion shall authorize from time to time. The Trust assets
allocated to a particular Investment Fund shall be invested by the Trustee
and/or one or more investment managers duly appointed in accordance with the
provisions of the Trust, as the case may be, in such type of property, whether
real, personal or mixed, as the Trustee is directed to acquire and hold for such
Investment Fund. Upon becoming a Participant in the Plan, each Participant shall
direct, in the manner prescribed by the Committee, that all amounts credited to
his or her Matching Account shall be invested, in such percentage multiples as
the Committee shall prescribe, in one or more of the Investment Funds authorized
by the Committee. Subject to such conditions and limitations as the Committee
may prescribe from time to time for application to all Participants on a uniform
basis, a Participant may change his or her investment direction with respect to
future contributions or redirect the investment of the amounts credited to his
or her Matching Account provided that notice of such change is delivered to or
in the manner directed by the Committee within such reasonable period of time
prior to the effective date thereof as the Committee may require.

     Section 4.3  Valuation and Adjustment of Accounts.  As of each Valuation
Date, the Trustee shall determine the fair market value of all assets of the
Trust with the value of the assets of each Investment Fund being separately
determined.  On the basis of such valuations and in accordance with such
procedures as may be specified from time to time by the Committee, the portion
of each Matching Account invested in a particular Investment Fund shall be
adjusted by the Committee to reflect its proportionate share of the income
collected and accrued, realized and unrealized profits and losses, expenses and
all other transactions attributable to that particular Investment Fund for the
valuation period then ended.  The amount of any distribution or forfeiture shall
be determined on the basis of the most recent valuation preceding the date of
distribution or forfeiture, as the case may be.


                                   ARTICLE V.

                                    VESTING

     Section 5.1  Vesting of Matching Accounts.  The amounts credited to the
Matching Account of a Participant shall become fully vested upon the occurrence
of any of the following events while the Participant is in the employ of (or on
authorized leave of absence from) an Employer or Affiliated Company: (i) the
completion of an Hour of Service by the Participant on or after his or her
Normal Retirement Date, (ii) the Participant's death, (iii) the Participant's
Permanent Disability, or (iv) a Change of Control.  Unless sooner vested
pursuant to the preceding sentence, the amounts credited to a Participant's
Matching Account shall vest in accordance with the following schedule:

              Years of Service
          Completed by Participant            Percentage Vested

                                  ARTICLE VI.

                                 DISTRIBUTIONS

     Section 6.1  Time and Form of Distribution. Distribution to a Participant
or beneficiary under this Article shall be made or commence being made no later
than 60 days after the close of the Plan Year in which the latest of the
following occurs:  (i) the Participant's Normal Retirement Date, (ii) the tenth
anniversary of the year in which the Participant commenced participation in the
Plan, or (iii) the Participant's separation from the employment of an Employer
for any reason other than his or her transfer to the employment of another
Employer or Affiliated Company.  In addition and any provision of this Plan to
the contrary notwithstanding, in the case of a Participant who is a five-percent
owner (as defined in Section 416(i) of the Code), distribution to such
Participant under the Plan shall be made or commence being made no later than
April 1 of the calendar year following the calendar year in which the
Participant attains age 70 1/2.  Distributions that commence being made pursuant
to the preceding sentence to a Participant who has not separated from the
employment of an Employer or Affiliated Company shall be made pursuant to
Section 6.2 as if the Participant had terminated employment at such time and
shall be made in accordance with the minimum distribution requirements of
Section 401(a)(9) of the Code and the regulations thereunder; provided, however,
that if a Participant elects to waive payment in the form of a Qualified Joint
and Survivor Annuity in accordance with Section 6.2, the alternative form of
distribution shall be payment of the minimum amounts required to be distributed
pursuant to Section 401(a)(9) of the Code and the regulations thereunder,
without recalculation of life expectancy (unless the Participant requests that
life expectancy be recalculated in accordance with Section 401(a)(9) of the Code
at the time and in the manner prescribed by the Committee), and with any amount
remaining upon the termination of the Participant's employment or death to be
paid in accordance with Section 6.2 or Section 6.3, whichever is applicable, but
with any payments adjusted or accelerated as necessary to satisfy the
requirements of Section 401(a)(9) of the Code and the regulations thereunder.
Subject to the provisions of this Article requiring that distributions be made
in the form of an annuity contract, distributions from the Plan shall be made in
cash.  Any provision of this Plan to the contrary notwithstanding, all
distributions from the Plan shall be made in accordance with Section 401(a)(9)
of the Code and the regulations thereunder.

     Section 6.2  Distribution of Retirement or Permanent Disability Benefit.

          (a) Except as otherwise provided in this Section, upon the
     Retirement or Permanent Disability of a Participant, the Vested Interest of
     such Participant shall be distributed to such Participant by the Trustee at
     the direction of the Committee in the form of a Qualified Joint and
     Survivor Annuity contract to be purchased from a company

                                      -12-
<PAGE>
 
     selected by the Committee and commencing in payment as soon as practicable
     unless the Participant's Vested Interest does not exceed and has never
     exceeded $5,000, in which event it will be distributed to the Participant
     as soon as practicable following his or her Retirement or Permanent
     Disability in the form of a single distribution. Notwithstanding the
     provisions of this Section 6.2, no distribution shall be made upon the
     Permanent Disability of a Participant prior to his or her Normal Retirement
     Date unless (i) such Participant elects to receive such distribution, or
     (ii) such Participant's Vested Interest does not exceed and has never
     exceeded $5,000.

          (b) Not more than 90 days prior to the date the Qualified Joint and
     Survivor Annuity contract is to commence in payment to a Participant, the
     Committee shall provide such Participant with a written explanation of (i)
     the terms and conditions of the Qualified Joint and Survivor Annuity, (ii)
     his or her right to make, and the effect of, an election to waive the
     Qualified Joint and Survivor Annuity form of benefit, (iii) the rights of
     his or her spouse with respect to the receipt and waiver of the Qualified
     Joint and Survivor Annuity, and (iv) the right to make, and the effect of,
     a revocation of an election to waive the Qualified Joint and Survivor
     Annuity.  The written explanation shall be required at least 30 days prior
     to the date the Qualified Joint and Survivor Annuity contract is to
     commence in payment; provided, however, that a Participant may elect (with
     any applicable spousal consent) to waive such requirement if the
     distribution to the Participant commences no earlier than 8 days after such
     explanation is provided.

          (c) After receiving the explanation described in (b) above, the
     Participant may elect at any time during the 90-day period ending on the
     date the annuity contract is to commence in payment to waive the Qualified
     Joint and Survivor Annuity form of benefit and also may revoke any such
     election during such period.  Any such election to waive a Qualified Joint
     and Survivor Annuity form of benefit by a married Participant will be
     effective only if the spouse of such Participant consents in writing within
     the 90-day period preceding the date distributions are to commence to both
     the election and the optional form of benefit selected by the Participant
     and such consent is witnessed by a notary public.

          (d) Any amount payable under the Plan upon the Retirement or
     Permanent Disability of a Participant who has elected to waive the
     Qualified Joint and Survivor Annuity form of benefit as provided above
     shall be distributed to such Participant by the Trustee at the direction of
     the Committee in one of the following forms to be selected by the
     Participant:

          (i)   by payment of the entire amount in a single distribution; or

          (ii)  by payment of the entire amount in substantially equal monthly,
                quarterly, or annual installments over a fixed period not
                extending beyond the life expectancy of the Participant or the
                joint life and last survivor expectancy of the Participant and
                his or her designated beneficiary. If a Participant who elected
                installment payments dies prior to the distribution of the

                                      -13-
<PAGE>
 
                entire amount of his or her Vested Interest, the remaining
                portion thereof shall be distributed to his or her beneficiary
                or beneficiaries, as determined in accordance with Section 6.3.

     Section 6.3  Distribution of Death Benefit.

          (a) Except as otherwise provided in this Section, upon the death of a
     Participant who is married, the Vested Interest of such Participant shall
     be distributed by the Trustee at the direction of the Committee to his or
     her surviving spouse in the form of a Qualified Preretirement Survivor
     Annuity contract to be purchased from a company selected by the Committee
     and commencing in payment as soon as practicable following the
     Participant's death.

          (b) The Committee shall provide each Participant with a written
     explanation of the Qualified Preretirement Survivor Annuity provided above,
     including the Participant's right to waive the distribution of such
     Qualified Preretirement Survivor Annuity with the consent of his or her
     spouse and to revoke any such waiver, within whichever of the following
     periods ends last: (i) the period beginning with the first day of the Plan
     Year in which the Participant attains the age of 32 and ending with the
     close of the Plan Year preceding the Plan Year in which the Participant
     attains the age of 35, (ii) the one-year period after the individual
     becomes a Participant, or (iii) the one-year period after separation from
     employment in the case of a Participant who separates before attaining age
     35.

          (c) Each Participant may elect at any time beginning on the first
     day of the Plan Year in which the Participant attains age 35 and ending on
     the date of such Participant's death to waive the Qualified Preretirement
     Survivor Annuity form of benefit provided above so that his or her entire
     benefit may be paid to his or her designated beneficiary. No election to
     waive the Qualified Preretirement Survivor Annuity will be effective upon
     the Participant's death unless such election designates a beneficiary that
     cannot be changed without spousal consent, the Participant's surviving
     spouse consents in writing to such election and such consent is witnessed
     by a notary public. A Participant may revoke any such election to waive the
     Qualified Preretirement Survivor Annuity at any time prior to his or her
     death.

          (d) Any amount payable under the Plan upon the death of a Participant
     who is not married or who is married but who has elected, as provided
     above, to waive the Qualified Preretirement Survivor Annuity and has
     designated a beneficiary, shall be distributed to the beneficiary
     designated by such Participant. Such designation shall be made in writing
     on a form prescribed by the Committee and, when filed with the Committee,
     shall become effective and remain in effect until changed by the
     Participant by the filing of a new beneficiary designation form with the
     Committee. If an unmarried Participant fails to so designate a beneficiary
     or in the event all of a Participant's designated beneficiaries are
     individuals who predecease the Participant, then the

                                      -14-
<PAGE>
 
     Committee shall direct the Trustee to distribute the amount payable under
     the Plan to such Participant's surviving spouse, if any, but if none, to
     such Participant's estate.

          (e) All distributions under this Section, other than the Qualified
     Preretirement Survivor Annuity provided above, shall be made to the
     beneficiary or beneficiaries by the Trustee at the direction of the
     Committee in a single distribution as soon as practicable following a
     Participant's death; provided, however, that if the Participant's Vested
     Interest exceeds or has ever exceeded $5,000, a Participant may elect (or
     if the Participant does not elect, his or her designated beneficiary may
     elect) that distributions be made in substantially equal monthly, quarterly
     or annual installments over a fixed period of time not extending beyond the
     life expectancy of the Participant's designated beneficiary.

          (f) Any provision of this Section 6.3 to the contrary notwithstanding,
     the surviving spouse of any deceased Participant may elect in writing after
     the Participant's death to receive the benefits otherwise payable to such
     surviving spouse in one of the forms provided in Section 6.3(e) above or in
     the form of a Qualified Preretirement Survivor Annuity commencing in
     payment as of such later date as the surviving spouse may elect, provided
     that such delayed payment commencement date complies with the provisions of
     Section 401(a)(9) of the Code and the regulations thereunder.

      Section 6.4  Distribution of Separation from Employment Benefit.  If a
Participant separates from the employment of an Employer or Affiliated Company
for any reason other than his or her Retirement, Permanent Disability, death or
transfer to the employment of another Employer or Affiliated Company, the
Matching Account of such Participant shall be retained in trust and shall
continue to be credited with applicable earnings as provided in Section 4.3, and
the Vested Interest of such Participant shall be distributed to such Participant
by the Trustee at the direction of the Committee upon such Participant's Normal
Retirement Date by payment of the entire amount in the form of a Qualified Joint
and Survivor Annuity contract to be purchased from a company selected by the
Committee and commencing in payment as soon as practicable thereafter (or, if
the Participant dies prior to his or her Normal Retirement Date, the Vested
Interest of such Participant under the Plan shall be distributed upon his or her
death in accordance with Section 6.3); provided, however, that (i) each such
Participant shall have the right to receive an early distribution of his or her
Vested Interest under the Plan in the form of a Qualified Joint and Survivor
Annuity contract to be purchased from a company selected by the Committee and
commencing in payment as soon as practicable following such election, or upon
satisfaction of the notice and waiver requirements of Section 6.2, in any other
form provided for distributions upon Retirement or Permanent Disability pursuant
to Section 6.2, and (ii) the Committee shall require a lump sum distribution of
any such Participant's entire Vested Interest as soon as practicable if such
Participant's Vested Interest does not exceed and has never exceeded $5,000.

     Section 6.5  Forfeitures.

          (a) Unless sooner forfeited as provided below, any unvested portion of
     the Matching Account of a Participant who separates from the employment of
     an Employer or Affiliated Company for any reason other than his or her
     Retirement, Permanent Disability, death or transfer to the employment of
     another Employer or Affiliated Company shall be forfeited upon the earlier
     of the date of such Participant's death or the date such Participant incurs
     five consecutive One Year Breaks in Service unless such Participant is
     reemployed by an Employer or Affiliated Company prior to such date.

          (b) (i)   If a Participant receives a complete distribution of his or
     her Vested Interest under Section 6.4 by the end of the second Plan Year
     following the year in which his or her separation from employment occurred
     under Section 6.4, any portion of such Participant's Matching Account which
     is not vested at the time of such distribution shall be forfeited at such
     time.

              (ii)  If a Participant who separates from the employment of an
     Employer or Affiliated Company for any reason other than his or her
     Retirement, Permanent Disability, death or transfer to the employment of
     another Employer or Affiliated Company, is not entitled to receive any
     distribution from the Plan due to the fact that such Participant has no
     Vested Interest, such Participant shall be deemed to have received a
     distribution from the Plan of his or her entire Vested Interest under the
     Plan and any amount credited to such Participant's Matching Account shall
     be forfeited at the time of such separation from employment.

              (iii)  If a Participant, any portion of whose Matching Account is
     forfeited pursuant to this subsection (b), is reemployed as a Covered
     Employee prior to incurring five consecutive One Year Breaks in Service,
     the amount so forfeited shall be restored to such individual's Matching
     Account out of current-year forfeitures or, if such forfeitures are
     insufficient, by an additional Employer contribution; provided, however,
     that no amount shall be restored to the Matching Account of an individual
     who previously received a distribution of the vested portion of his or her
     Matching Account unless he or she repays to the Plan for crediting to his
     or her Matching Account, while a Covered Employee and within five years of
     the date of such reemployment, the full amount previously distributed from
     such Account.

          (c) If a Participant who has not yet incurred five consecutive One
     Year Breaks in Service receives a distribution under Section 6.4 after the
     end of the second Plan Year following the year in which his or her
     separation from employment occurred, any portion of such Participant's
     Matching Account which is not vested at the time of such distribution shall
     be retained in such Account and shall be forfeited upon the earlier of the
     date of such Participant's death or the date such Participant incurs five
     consecutive One Year Breaks in Service unless such Participant is
     reemployed by an Employer or Affiliated Company prior to such date.  If a
     Participant receives a distribution from the Plan after the end of the
     second Plan Year following the year in which his or her separation from
     employment occurred and is reemployed by an Employer or Affiliated Company
     prior to incurring five consecutive One Year Breaks in Service, then the

                                      -16-
<PAGE>
 
     unvested balance in his or her Matching Account shall be transferred to a
     segregated account for such Participant and the amount that the Participant
     is entitled to receive from such segregated account as of any later date
     shall be an amount equal to X, which amount shall be determined in
     accordance with the following formula:  X = P(AB + D) - D, where P is the
     Participant's vested percentage at such later date, AB is the amount in his
     or her segregated account at such later date, and D is the amount
     distributed to the Participant in connection with his or her earlier
     separation from employment.

          (d) All amounts forfeited under the Plan shall be credited to a
     forfeiture account and invested by the Trustee at the direction of the
     Committee in its discretion until such forfeited amounts and any earnings
     attributable thereto are applied in accordance with Section 3.5.

     Section 6.6  Distributions to Minors and Persons Under Legal Disability.
If any distribution under the Plan becomes payable to a minor or other person
under a legal disability, such distribution may be made to the duly appointed
guardian or other legal representative of the estate of such minor or person
under legal disability.

     Section 6.7  Benefits Payable to Missing Participant or Beneficiary.  If
the Committee cannot locate a Participant or beneficiary entitled to a
distribution under this Plan within a period of three years after such
Participant or beneficiary becomes entitled to the distribution, the amounts
credited to the Matching Account of such Participant or beneficiary shall be
forfeited; provided, however, that if a claim for any such forfeited amounts is
subsequently made by any person entitled to the distribution, such forfeited
amounts shall be restored (without adjustment for earnings or appreciation) out
of current-year forfeitures, or if such forfeitures are insufficient, by an
additional Employer contribution.

     Section 6.8  Transfer of Eligible Rollover Distribution.  If a Participant
is entitled to receive an eligible rollover distribution (as defined in Section
402(c) of the Code and the regulations thereunder) from the Plan, such
Participant may elect to have the Committee direct the Trustee to transfer the
entire amount of such distribution directly to any of the following specified by
such Participant:  an individual retirement account described in Section 408(a)
of the Code, an individual retirement annuity described in Section 408(b) of the
Code (other than an endowment contract), a defined contribution plan qualified
under Section 401(a) of the Code the terms of which permit rollover
contributions or an annuity plan described in Section 403(a) of the Code.  If
the surviving spouse of a deceased Participant is entitled to receive an
eligible rollover distribution from the Plan, such surviving spouse may elect to
have the Committee direct the Trustee to transfer the entire amount of such
distribution directly to either an individual retirement account described in
Section 408(a) of the Code or an individual retirement annuity described in
Section 408(b) of the Code (other than an endowment contract) specified by such
surviving spouse.  If an alternate payee under a qualified domestic relations
order (as defined in Section 414(p) of the Code) is the spouse or former spouse
of the Participant specified in the qualified domestic relations order, this
Section shall apply to such alternate payee as if the alternate payee were a
Participant.  A distributee of an eligible rollover distribution who is 

                                      -17-
<PAGE>
 
entitled to make an election under this Section may specify that some portion
less than the entire amount of such distribution be transferred in accordance
with this Section.

     Section 6.9  Qualified Domestic Relations Orders.  Any provision of this
Plan to the contrary notwithstanding:

          (a) The Committee shall establish and maintain for each alternate
     payee named with respect to a Participant under a domestic relations order
     which is determined by the Committee to be a qualified domestic relations
     order (as defined in Section 414(p) of the Code) such separate accounts as
     the Committee may deem to be necessary or appropriate to reflect such
     alternate payee's interest in the Matching Account of such Participant.
     Such alternate payee's accounts shall be credited with the alternate
     payee's interest in the Participant's Matching Account as determined under
     such qualified domestic relations order.  The alternate payee may change
     investment direction with respect to his or her account balances in
     accordance with Section 4.2 in the same manner as the Participant.

          (b) Except to the extent otherwise provided in the qualified domestic
     relations order naming an alternate payee with respect to a Participant,
     (i) the alternate payee may designate a beneficiary on a form prescribed by
     and filed with the Committee, (ii) if no such beneficiary is validly
     designated or if the designated beneficiary is a person who predeceases the
     alternate payee, the beneficiary of the alternate payee shall be the
     alternate payee's estate, and (iii) the beneficiary of the alternate payee
     shall be accorded under the Plan all of the rights and privileges of the
     beneficiary of a Participant.

          (c) An alternate payee named with respect to a Participant shall be
     entitled to receive a distribution from the Plan in accordance with the
     qualified domestic relations order naming such alternate payee.  Such
     distribution may be made only in a form provided under the Plan and shall
     include only such amounts as are vested.  If a qualified domestic relations
     order so provides, a lump sum distribution of the total vested amount
     credited to the alternate payee's account may be made to the alternate
     payee at any time prior to the date the Participant named in such qualified
     domestic relations order attains his or her earliest retirement age (as
     defined in Section 414(p)(4)(B) of the Code).

          (d) If a portion of any unvested amount credited to the Matching
     Account of a Participant named in the qualified domestic relations order is
     credited to the account of the alternate payee named in such qualified
     domestic relations order, the portion credited to such account of the
     alternate payee shall vest and/or be forfeited at the same time and in the
     same manner as such Matching Account of the Participant.

                              PLAN ADMINISTRATION

     Section 7.1  Committee.  The Company shall be the plan administrator of the
Plan.  The Plan shall be administered on behalf of the Company by a Committee
composed of at least three individuals appointed by the Board of Directors of
the Company.  Each member of the Committee so appointed shall serve in such
office until his or her death, resignation or removal by the Board of Directors
of the Company.  The Board of Directors of the Company may remove any member of
the Committee at any time by giving written notice thereof to the members of the
Committee.  Vacancies shall likewise be filled from time to time by the Board of
Directors of the Company.  The members of the Committee shall receive no
remuneration from the Plan for their services as Committee members.

     Section 7.2  Powers, Duties and Liabilities of the Committee.  The
Committee shall have discretionary and final authority to interpret and
implement the provisions of the Plan, including without limitation authority to
determine eligibility for benefits under the Plan, and shall perform all of the
duties and exercise all of the powers and discretion granted to it under the
terms of the Plan.  The Committee shall act by a majority of its members at the
time in office and such action may be taken either by a vote at a meeting or in
writing without a meeting.  The Committee may by such majority action authorize
any one or more of its members to execute any document or documents on behalf of
the Committee, in which event the Committee shall notify the Trustee in writing
of such action and the name or names of its member or members so authorized to
act. Every interpretation, choice, determination or other exercise by the
Committee of any discretion given either expressly or by implication to it shall
be conclusive and binding upon all parties directly or indirectly affected,
without restriction, however, on the right of the Committee to reconsider and
redetermine such actions.  In performing any duty or exercising any power herein
conferred, the Committee shall in no event perform such duty or exercise such
power in any manner which discriminates in favor of Highly Compensated
Employees.  The Employers shall indemnify and hold harmless each member of the
Committee against any claim, cost, expense (including attorneys' fees), judgment
or liability (including any sum paid in settlement of a claim with the approval
of the Employers) arising out of any act or omission to act as a member of the
Committee appointed under this Plan, except in the case of willful misconduct.

     Section 7.3  Rules, Records and Reports.  The Committee may adopt such
rules and procedures for the administration of the Plan as are consistent with
the terms hereof, and shall keep adequate records of the Committee's proceedings
and acts and of the status of the Participants' Matching Accounts.  The
Committee may employ such agents, accountants and legal counsel (who may be
agents, accountants or legal counsel for an Employer) as may be appropriate for
the administration of the Plan.  The Committee shall at least annually provide
each Participant with a report reflecting the status of his or her Matching
Account in the Trust and shall cause such other information, documents or
reports to be prepared, provided and/or filed as may be necessary to comply with
the provisions of the Employee Retirement Income Security Act of 1974 or any
other law.

     Section 7.4  Administration Expenses and Taxes.  The Employers may, but
shall not be required to, pay all reasonable and necessary expenses (including
the fees of agents, accountants and legal counsel) incurred by the Committee in
connection with the administration of the Plan. Unless otherwise paid by the
Employers in their absolute discretion, such expenses shall be paid from and
charged against the assets of the Trust.  Should any tax of any character
(including transfer taxes) be levied upon the Trust assets or the income
therefrom, such tax shall be paid from and charged against the assets of the
Trust.


                                 ARTICLE VIII.

                           AMENDMENT AND TERMINATION

     Section 8.1  Amendment.  The Company shall have the right and power at any
time and from time to time to amend this Plan, in whole or in part, on behalf of
all Employers.  Any such amendment made by the Company shall be made by or
pursuant to a resolution duly adopted by the Board of Directors of the Company,
and shall be evidenced by such resolution or by a written instrument executed by
such person as the Board of Directors of the Company shall authorize for such
purpose.  With the consent of the Company and subject to such procedure as it
may prescribe, each Employer shall have the right and power at any time and from
time to time to amend this Plan, in whole or in part, with respect to the Plan's
application to the Participants of the particular amending Employer and the
assets held in the Trust for their benefit, or to transfer such assets or any
portion thereof to a new trust for the benefit of such Participants.  However,
in no event shall any amendment or new trust permit any portion of the trust
fund to be used for or diverted to any purpose other than the exclusive benefit
of the Participants and their beneficiaries, nor shall any amendment or new
trust reduce a Participant's Vested Interest under the Plan.

     Section 8.2  Termination.  The Board of Directors of the Company shall
have the right and power at any time to terminate this Plan on behalf of all
Employers, or to terminate this Plan as it applies to the Participants who are
or were employees of any particular Employer, by giving written notice of such
termination to the Committee and Trustee.  Any provision of this Plan to the
contrary notwithstanding, upon the termination or partial termination of the
Plan as to any Employer, or in the event any Employer should completely
discontinue making contributions to the Plan without formally terminating it,
all amounts credited to the Matching Accounts of the affected Participants of
that particular Employer shall be fully vested.


                                  ARTICLE IX.

                             TOP-HEAVY PROVISIONS

     Section 9.1  Top-Heavy Definitions.  Unless the context clearly indicates
otherwise, when used in this Article:

                                      -20-
<PAGE>
 
          (a) "Top-Heavy Plan" means this Plan if, as of the Determination Date,
     the aggregate of the Matching Accounts of Key Employees under the Plan
     exceeds 60% of the aggregate of the Matching Accounts of all Participants
     and former Participants under the Plan.  The aggregate of the Matching
     Accounts of any Participant or former Participant shall include any
     distributions (other than related rollovers or transfers from the Plan
     within the meaning of regulations under Section 416(g) of the Code) made
     from such individual's Matching Account during the Plan Year or any of the
     four preceding Plan Years, but shall not include any unrelated rollovers or
     transfers (within the meaning of regulations under Section 416(g) of the
     Code) made to such individual's account after December 31, 1983.  The
     Matching Account of any Participant or former Participant who (i) is not a
     Key Employee for the Plan Year in question but who was a Key Employee in a
     prior Plan Year, or (ii) has not completed an Hour of Service during the
     five-year period ending on the Determination Date, shall not be taken into
     Matching Account.  The determination of whether the Plan is a Top-Heavy
     Plan shall be made after aggregating all other plans of an Employer and any
     Affiliated Company qualifying under Section 401(a) of the Code in which a
     Key Employee is a participant or which enables such a plan to meet the
     requirements of Section 401(a)(4) or 410 of the Code, and after aggregating
     any other plan of an Employer or Affiliated Company, which is not already
     aggregated, if such aggregation group would continue to meet the
     requirements of Sections 401(a)(4) and 410 of the Code and if such
     permissive aggregation thereby eliminates the top-heavy status of any plan
     within such permissive aggregation group.  The determination of whether
     this Plan is a Top-Heavy Plan shall be made in accordance with Section
     416(g) of the Code.

          (b) "Determination Date" means, for purposes of determining whether
     the Plan is a Top-Heavy Plan for a particular Plan Year, the last day of
     the preceding Plan Year.

          (c) "Key Employee" means any Employee or former Employee (including a
     beneficiary of such Employee or former Employee) who at any time during the
     Plan Year or any of the four preceding Plan Years is:

              (1) an officer of the Employer who has Compensation for any such
          Plan Year greater than 50% of the amount in effect under Section
          415(b)(1)(A) of the Code for such Plan Year;

              (2) one of the 10 Employees owning (or considered as owning
          within the meaning of Section 318 of the Code) the largest interests
          in excess of 0.5% in an Employer or Affiliated Company and having
          Compensation for such Plan Year of more than the limitation in effect
          under Section 415(c)(1)(A) of the Code;

              (3) a person owning (or considered as owning within the meaning
          of Section 318 of the Code) more than 5% of the outstanding stock of
          an Employer or stock possessing more than 5% of the total combined
          voting power of all stock of an Employer; or

                                      -21-
<PAGE>
 
              (4) a person who has Compensation for such Plan Year from an
          Employer of more than $150,000 and who would be described in paragraph
          (3) hereof if 1% were substituted for 5% in each place it appears in
          such paragraph.

     For the purposes of applying Section 318 of the Code to this subsection
     (c), subparagraph (C) of Section 318(a)(2) of the Code shall be applied by
     substituting 5% for 50%.  The rules of subsections (b), (c) and (m) of
     Section 414 of the Code shall not apply for purposes of determining
     ownership in an Employer under this subsection (c).

          (d) "Non-Key Employee" means any Employee or former Employee
     (including a beneficiary of such Employee or former Employee) who is not a
     Key Employee.

     Section 9.2  Minimum Contribution Requirement.  Any provision of this Plan
to the contrary notwithstanding, if the Plan is a Top-Heavy Plan for any Plan
Year, then the Employers will contribute to the Matching Account of each Non-Key
Employee who is both eligible to participate and in the employ of an Employer on
the last day of such Plan Year, an amount which, when added to the total amount
of contributions and forfeitures otherwise allocable under the Plan and any
other plan that may be aggregated with the Plan for such Non-Key Employee for
such year, shall equal the lesser of (i) 3% of such Non-Key Employee's
Compensation for such year or (ii) the amount of contributions and forfeitures
(expressed as a percentage of Compensation allocable under the Plan for the Key
Employee for whom such percentage is the highest for the Plan Year after taking
into account contributions under other defined contribution plans maintained by
the Employer in which a Key Employee is a participant (as well as any other plan
of an Employer which enables such a plan to meet the requirements of Section
401(a)(4) or 410 of the Code); provided, however, that no minimum contribution
shall be made for a Non-Key Employee under this Section for any Plan Year if the
Employer maintains another qualified plan under which a minimum benefit or
contribution is being accrued or made for such Plan Year for the Non-Key
Employee in accordance with Section 416(c) of the Code.  A Non-Key Employee who
is not a Participant, but for whom a contribution is made pursuant to this
Section, shall be accorded all of the rights and privileges of a Participant
under the Plan except that no contributions (other than contributions pursuant
to this Section) shall be made for or on behalf of such Non-Key Employee until
he or she meets the eligibility and participation requirements of Article II.


                                  ARTICLE X.

                       MISCELLANEOUS GENERAL PROVISIONS

     Section 10.1  Spendthrift Provision.  No right or interest of any
Participant or beneficiary under the Plan may be assigned, transferred or
alienated, in whole or in part, either directly or by operation of law, and no
such right or interest shall be liable for or subject to any debt, obligation or
liability of such Participant or beneficiary; provided, however, that nothing
herein shall prevent the payment of amounts from a Participant's Matching
Account under the Plan in 

                                      -22-
<PAGE>
 
accordance with the terms of a court order which the Committee has determined to
be a qualified domestic relations order (as defined in Section 414(p) of the
Code).

     Section 10.2  Claims Procedure.  If any person (hereinafter called the
"Claimant") feels that he or she is being denied a benefit to which he or she is
entitled under the Plan, such Claimant may file a written claim for said benefit
with any member of the Committee.  Within 60 days of the receipt of such claim
the Committee shall determine and notify the Claimant as to whether he or she is
entitled to such benefit.  Such notification shall be in writing and, if denying
the claim for benefit, shall set forth the specific reason or reasons for the
denial, make specific reference to the pertinent provisions of the Plan, and
advise the Claimant that he or she may, within 60 days of the receipt of such
notice, in writing request to appear before the Committee for a hearing to
review such denial.  Any such hearing shall be scheduled at the mutual
convenience of the Committee or its designated representative and the Claimant,
and at such hearing the Claimant and/or his or her duly authorized
representative may examine any relevant documents and present evidence and
arguments to support the granting of the benefit being claimed.  The final
decision of the Committee with respect to the claim being reviewed shall be made
within 60 days following the hearing thereon and the Committee shall in writing
notify the Claimant of its final decision, again specifying the reasons therefor
and the pertinent provisions of the Plan upon which such decision is based.  The
final decision of the Committee shall be conclusive and binding upon all parties
having or claiming to have an interest in the matter being reviewed.

     Section 10.3  Maximum Contribution Limitation.  Any provision of this Plan
to the contrary notwithstanding, the sum of (i) the Employer contributions, (ii)
the forfeitures, and (iii) the Participant contributions (excluding rollover
contributions and employee contributions to a simplified employee pension
allowable as a deduction, each within the meaning specified in Section 415(c)(2)
of the Code), allocated to a Participant with respect to a Plan Year shall in no
event exceed the lesser of $30,000 (as adjusted pursuant to Section 415(d) of
the Code to take into account any cost-of-living increase) or 25% of such
Participant's Compensation for that year.  For the purposes of applying the
limitation imposed by this Section, each Employer and its Affiliated Companies
shall be considered a single employer, and all defined contribution plans
(meaning plans providing for individual accounts and for benefits based solely
upon the amounts contributed to such accounts and any forfeitures, income,
expenses, gains and losses allocated to such accounts) described in Section
415(k) of the Code, whether or not terminated, maintained by an Employer or its
Affiliated Companies shall be considered a single plan.  If the total amount
allocable to a Participant's Matching Account for a particular Plan Year would,
but for this sentence, exceed the foregoing limitation, any amounts allocated to
such Participant's Matching Account in excess of the foregoing limitation shall
be credited to a suspense account and thereafter used to reduce Matching
Contributions for such Plan Year (and, if necessary, the next succeeding year).
No adjustment shall be made to such suspense account to reflect income, profits
or losses, expenses or other transactions affecting the Trust.

     Section 10.4  Employment Noncontractual.  The establishment of this Plan
shall not enlarge or otherwise affect the terms of any Employee's employment
with an Employer and an 

                                      -23-
<PAGE>
 
Employer may terminate the employment of any Employee as freely and with the
same effect as if this Plan had not been adopted.

     Section 10.5  Limitations on Responsibility.  The Employers do not
guarantee or indemnify the Trust against any loss or depreciation of its assets
which may occur, nor guarantee the payment of any amount which may become
payable to a Participant or his or her beneficiaries pursuant to the provisions
of this Plan.  All payments to Participants and their beneficiaries shall be
made by the Trustee at the direction of the Committee solely from the assets of
the Trust and the Employers shall have no legal obligation, responsibility or
liability for any such payments.

     Section 10.6  Merger or Consolidation.  In no event shall this Plan be
merged or consolidated into or with any other plan, nor shall any of its assets
or liabilities be transferred to any other plan, unless each Participant would
be entitled to receive a benefit if the plan in which he or she then
participates terminated immediately following such merger, consolidation or
transfer, which is equal to or greater than the benefit he or she would have
been entitled to receive if the Plan had been terminated immediately prior to
such merger, consolidation or transfer.

     Section 10.7  Applicable Law.  This Plan shall be governed and construed
in accordance with the internal laws (and not the principles relating to
conflicts of laws) of the State of Texas except where superseded by federal law.

     IN WITNESS WHEREOF, this Plan has been established by Titan Resources I,
Inc. this 24th day of August, 1998, to be effective as of September 1, 1998.
