contemplated by the Transaction Agreement or another transaction that would
result in the shareholders of the Company receiving in excess of $17.00 per

the Issuer to consummate the transactions contemplated by the Transaction
Agreement or another transaction that would result in the shareholders of the
Company receiving in excess of $17.00 per share.

      The Reporting Persons are continuously reviewing the status of the
Transaction Agreement, the Issuer's business affairs and financial condition, as
well as all aspects of the Reporting Persons' shareholdings. The Reporting
Persons currently plan to continue to acquire additional shares of North Face

they may sell all or any part of their shareholdings at any time depending on

                    ---------------------                                   
Capital Contribution in cash in the amount set forth opposite such Partner's
name in the Schedule.  After the formation of the Partnership, any new Partner
may make initial Capital Contributions in any amount approved by the General
Partner and shall be bound by the provisions of this Agreement.  Additional
Capital Contributions to the Partnership may be made by Partners only in
accordance with the provisions of Section 3.02.

     SECTION 3.02.  Additional Capital Contributions.  At the beginning of any
                    --------------------------------                          
fiscal quarter of the Partnership, any Partner may make Additional Capital
Contributions to the Partnership as long as such Additional Capital Contribution
is delivered within five days after the first day that begins such quarter and
the General Partner, in its sole discretion has approved such Additional Capital
Contribution.   All Additional Capital Contributions shall be delivered to the
General Partner for the benefit of the Partnership in cash, certified or
cashier's check or Federal funds wire transfer.  The General Partner shall never
permit its Partnership Percentage to be less than one percent (1%), and shall
make such Additional Capital Contributions as may be necessary to maintain such
minimum Partnership Percentage.

     SECTION 3.03.  Partnership Percentages.  A Partnership Percentage shall be
                    -----------------------                                    
determined for each Partner for each Accounting Period and shall be set forth in
a schedule which shall be filed with the records of the Partnership.

     SECTION 3.04.   Capital Accounts.
                     ---------------- 

     (a) Unless and until the General Partner determines that such would not be
in the best interest of the Partners and the Partnership (in which case Capital
Accounts shall be maintained in accordance with generally accepted accounting
principles), the Partnership shall establish and maintain a capital account
("Capital Account") for each Partner in accordance with Section 704(b) of the
Code and Treasury Regulations Section 1.704-1(b)(2)(iv). If the General Partner
makes the determination provided in the preceding sentence, he shall promptly
give notice to the Partners of such decision, prior to taking any action
hereunder, with such notice to include a description of the proposed change and
its consequences.  Except as provided in, Section 3.04(b) and otherwise by this
Agreement, the Capital Account balance of each Partner shall be credited
(increased) by (i) the amount of money contributed by such Partner to the
capital of the Partnership, (ii) the fair market 

                                      11
<PAGE>
 
value of property contributed by such Partner to the capital of the Partnership
(net of liabilities secured by such property that the Partnership assumes or
takes subject to), and (iii) such Partner's allocable share of Partnership
income and gain (or items thereof) including income and gain exempt from federal
taxation, and the Capital Account balance of each Partner shall be debited
(decreased) by (i) the amount of cash distributed to such Partner, (ii) the fair
market value of property distributed to such Partner (net of liabilities secured
by such property which the Partner assumes or takes subject to), and (iii) of
such Partner's share of Partnership losses, depreciation and other deductions,
including such Partner's share of expenditures of the Partnership described in
Section 705(a)(2)(B) of the Code. Notwithstanding the foregoing, a Partner's
Capital Account shall not be adjusted to reflect gain or loss attributable to
the disposition of property contributed by such Partner to the extent such
Partner's Capital Account reflected such inherent gain or loss in the property
on the date of its contribution to the Partnership.

     (b) On the opening of business on any Adjustment Date, the Capital Accounts
of all the Partners shall be adjusted to reflect the manner in which the
unrealized income, gain, loss and deduction inherent in all the Partnership's
property (that has not previously been reflected in the Capital Accounts) would
be allocated among the Partners if there were a taxable disposition of all such
property on such Adjustment Date.  "Adjustment Date" means the effective day (i)
of a distribution of cash and/or property to a Partner in complete or partial
liquidation of such Partner's interest in the Partnership (including
distributions made pursuant to Sections 4.01 and 4.02 hereof); (ii) of a
distribution in liquidation of the Partnership; (iii) the admission to the
Partnership of one or more Limited Partners pursuant to Section 5.01 hereof;
(iv) of any other non-pro rata contribution to or distribution from the
Partnership, including, without limitation, additional capital contributions; or
(v) of the day after the last day of the Fiscal Year.

     SECTION 3.05.  Deficit Capital Account Balances.  Upon liquidation of the
                    --------------------------------                          
Partnership, no Limited Partner with a deficit balance in its Capital Account
shall have any obligation to restore such deficit balance, or to make any
contribution to the capital of the Partnership, except to the extent such
Limited Partner is personally liable to make contributions to the capital of the
Partnership pursuant to Section 1.04 of this Agreement.  Upon liquidation of the
partnership, the General Partner shall be obligated to contribute to the capital
of the Partnership within ninety (90) days after the date of such liquidation an
amount equal to his deficit Capital Account balance which amount shall be paid
to the creditors of the Partnership or distributed to the other Partners in
accordance with their positive Capital Account balances.

     SECTION 3.06.  Allocation of Net Profits  and Net Loss.
                    ----------------------------------------

     (a) Net Profits and Net Losses for each Accounting Period from the
         operations of the Partnership shall be determined in accordance with
         the method of accounting and books and records of the Partnership.
         Except as provided in Sections 3.06(b), (c) and (d) and 3.07, Net
         Profits and Net Losses attributable to each Accounting Period shall be
         allocated among the Partners as follows:

                                      12
<PAGE>
 
          (i)  First, each Partner shall preliminarily be allocated Net Profits
               and Net Losses during the Accounting Period, pro rata in
               accordance with their Partnership Percentages for such Accounting
               Period; and 

          (ii) Second, notwithstanding Section 3.06(a)(i), at the end of each
               Fiscal Year, after giving effect to the allocations provided for
               in Section 3.06(a)(i), 20% of the amount, if any, by which Net
               Profits for such Fiscal Year exceed Net Losses for such Fiscal
               Year shall be reallocated to the General Partner.
 
     (b) Notwithstanding anything to the contrary contained herein, items of
income, gain, loss and deduction with respect to an adjustment to the Partners'
Capital Accounts pursuant to Section 3.04(b) to reflect a revaluation of the
property of the Partnership shall be allocated among the Partners so as to take
account of the adjustments to the Partner's Capital Accounts as required in
Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(g), as
currently in effect.

     (c) In accordance with Code Sections 704(b), 704(c) and the Regulations
thereunder, income, gain, loss and deduction with respect to (i) any property
contributed to the capital of the Partnership, and (ii) all property owned by
the Partnership on each Adjustment Date, shall, solely for tax purposes, be
allocated among the Partners so as to take account of any variation between the
adjusted basis of such property to the Partnership for federal income tax
purposes and its value on, as the case may be, the date of contribution or the
Adjustment Date.

     (d) For income tax purposes, allocations of income or loss (and items
thereof) shall be made in accordance with the foregoing allocations of income
and loss for financial purposes.

     (e) As between a Partner who has transferred all or part of its interest in
the Partnership and its transferee, all items of income, gain, deduction and
loss, for any year shall be apportioned on the basis of the number of days in
each such year that each was the holder of such interest (making adjustments
necessary to comply with the provisions of Section 706(d)(2) of the Code),
without regard to the results of the Partnership's operations during the period
before and after the date of such transfer, provided that if both the transferor
and transferee consent thereto a special closing of the books shall be had as of
the effective date of such transfer and the apportionment of items of income and
gain, and deduction and loss, shall be made on the basis of actual operating
results.

     SECTION 3.07.  Qualified Income Offset Provision.  Notwithstanding anything
                    ---------------------------------                           
else to the contrary contained herein, to the extent that the allocation of any
loss or deduction would cause the deficit Capital Account balance of any Partner
to exceed the dollar amount that such Partner is obligated to restore upon
liquidation of the Partnership as of the end of the Partnership's taxable year
to which such allocation relates, such Partner will not be allocated a loss or
deduction which will cause or increase a deficit balance in such Partner's
Capital Account in excess of such amount.  For purposes of this subsection, the
Capital Account of each Partner shall be reduced (a) for any distributions that,
as of the end of such year, reasonably are expected to be made to such Partner
to the extent they exceed offsetting increases to such Partner's Capital Account
that reasonably are 

                                      13
<PAGE>
 
expected to occur during (or prior to) the Partnership taxable years in which
such distributions reasonably are expected to be made, (b) adjustments that as
of the end of such year reasonably are expected to be made for depletion
adjustments, and (c) allocations that, as of the end of such year, reasonably
are expected to be made pursuant to Code Section 704(e)(2) (dealing with family
partnerships), Code Section 706(d) (dealing with changes in Partners' interests)
and Treasury Regulation Section 1.751-1 (dealing with unrealized receivables and
inventory items), all as described in Treasury Regulation Section 1.704-
1(b)(2)(ii)(d). A Partner who unexpectedly receives an adjustment, allocation or
distribution described immediately above which causes or increases a deficit
balance in such Partner's Capital Account (in excess of any dollar amount of
such deficit balance that such Partner is obligated to restore upon liquidation,
as of the end of the Partnership's taxable year to which such allocation
relates) will be allocated items of income and gain in an amount and manner
sufficient to eliminate such deficit balance as quickly as possible.

     To the extent this Section 3.07 prevents the allocation of a deduction or
loss to a Partner, such deduction or loss shall be allocated between the
Partners in accordance with their interests in the Partnership as determined
under Treasury Regulation Section 1.704-1(b)(3).

     SECTION 4.01.  Earnings Distributions.  Unless the General Partner, in its

sole discretion, decides otherwise, all net income for each Fiscal Year from the
operations of the Partnership shall be retained by the Partnership for the
benefit of the Partners' Capital Accounts.  The General Partner may, in its sole
discretion, make such distributions of net income to enable each Partner to pay
his or her federal income liability with respect to such Partner's distributable
share of the Partnership's federal income tax liability.

     SECTION 4.02.  Withdrawals.  Should any Limited Partner desire to withdraw
                    -----------                                                
any portion of the positive balance of his Capital Account (as adjusted pursuant
to Article VII hereof), other than the distributions contemplated by Section
4.01 hereof, such Limited Partner or Partners shall notify the General Partner
in writing of such intent no later than thirty (30) days before the end of the
Fiscal Year.  Any such withdrawal may only be effective as of the end of a
Fiscal Year.  All such withdrawals from the Capital Accounts of the withdrawing
Limited Partner or Partners shall be paid in cash or, at the sole option of the
General Partner, by distribution of Partnership property valued in accordance
with this Agreement to the withdrawing Limited Partner or Partners by the
Partnership as soon as reasonably practicable after the books of the Partnership
are closed with respect to such Fiscal Year and the Partnership's information
tax return for such Fiscal Year has been prepared.   The General Partner may, at
its sole option, estimate the withdrawing Limited Partner's Capital Account as

Section 3.06(a)(ii),  and may make a payment in partial satisfaction of the
amount that the Limited Partner's seeks to withdraw, before the books are closed
and the Partnership's information tax returns are completed for such Fiscal
Year.  The 

                                      14
<PAGE>
 
General Partner may, in its sole discretion, permit a Limited Partner to
withdraw any portion of the positive balance of his Capital Account as permitted
in this Section 4.02 at the end of each fiscal quarter of the Partnership in the
case of special circumstances. However, any such withdrawal shall comply in all
respects with the provisions of this Agreement applicable to annual withdrawals
of capital specified in this Section 4.02.

     SECTION 4.03.  Audit.  In the event that the Partnership makes any

Partnership audit, are determined to be in excess of the distribution properly
allowable hereunder, such Partner shall promptly return to the Partnership such
excess together with interest thereon from the date of  receipt of such excess
to the date of repayment at the prime or base rate of interest announced from
time to time by NationsBank of Texas, N.A., or its successor.

Fiscal Year is completed. No approval or consent of any Limited Partner shall be
required for the withdrawal of such incumbent General Partner, whether or not
such withdrawal ultimately results in termination and liquidation of the
Partnership.

     (b) The withdrawal of the incumbent General Partner, without due succession

more persons, firms, corporations or other entities (the "Terminating Party") to

exercised by the General Partner under Sections 7.01 and 7.02, and the interest

due course.

     (c) In the event of an event of withdrawal (as defined in the Texas Act) of

Partnership have been wound up in due course in accordance with Sections 7.01
and 7.02 hereof, and his or its legal representative shall be entitled to
receive the positive balance of his or its Capital Account in accordance with
Sections 7.01 and 7.02 hereof, except as provided in Sections 1.04 and 6.03

other dates as an evaluation is to be determined in accordance with the terms of
this Agreement, the General Partner shall determine or cause to be determined

Security shall be determined as follows:

     (a) marketable Securities listed on a national securities exchange or
National Association of Securities Dealers' Automated Quotation National Market

last bid price on the date of valuation;

     (b) marketable Securities traded in the over-the-counter market and
reported in the National Association of Securities Dealers' Automated Quotation
system will be valued at the closing bid price as reported by such system;

     (c) Securities (other than Securities of a type specified in clause (a) or

Partner or the Partnership, as the case may be, shall pay the purchase price to
the  selling Limited Partner as soon as reasonably practicable after the books
of the Partnership are closed with respect to such fiscal quarter (and if such
fiscal quarter is the last quarter of the Fiscal Year, as soon as reasonably
practicable after the Partnership's information tax return for such Fiscal Year
has been prepared).

Code and the Treasury Regulations promulgated thereunder, and the Partners
further agree as follows:

     (b) The TMP shall have a continuing obligation to provide the Internal
Revenue Service with sufficient information so that proper notice can be mailed
to all Partners as provided in Section 6223 of the Code, and the Partners shall
furnish the TMP with such information (including information specified in
Section 6230(e) of the Code) as the TMP may reasonably request for such purpose.

     (c) The TMP shall keep each Partner informed of all administrative and/or
judicial proceedings for the adjustment of Partnership items (as defined in

Partners of such settlement agreement and its terms within 30 days after the
date of such settlement.

     (f) If the TMP elects not to file suit concerning an administrative
adjustment or request for administrative adjustment and another Partner elects

intention and the forum or forums in which such suit shall be filed shall be
agreed to by all of the Partners.

     (g) Each Partner shall be entitled to participate in all administrative
proceedings with the Internal Revenue Service, as provided by Code Section
6224(a).

     (h) The obligations imposed on the TMP and participation rights afforded
the Partners by this Agreement and Sections 6221 through 6232 of the Code may
not be restricted or limited in any fashion by the TMP or any Partner or
Partners without the written consent of all of the Partners.

     (i) The TMP shall have, subject to the prior approval of Partners holding a
majority of Partnership Percentages, the right to extend the statute of
limitations, file a request for an administrative adjustment, file suit
concerning any tax refund or deficiency relating to any Partnership
administrative adjustment or enter into any settlement agreement relating to any
Partnership item of income, gain, loss, deduction or credit for any taxable year
of the Partnership.

     SECTION 2.06.  Facilities.   The Partnership shall share office space with
                    ----------

     SECTION 2.07.  Compensation.   The General Partner shall charge a

Partner).  Such management fee shall be accrued against the Capital Accounts of
the Partners of the Partnership at the end of each fiscal quarter of the
Partnership at a rate of one quarter of one percent (0.25%) of the value of
total assets as of the end of each fiscal quarter.  If a Limited Partner
withdraws capital at a time other than the end of a Fiscal Year in accordance
with Section 4.02, the Partnership may, in the sole discretion of the General
Partner, charge the Limited Partner a withdrawal fee equal to two percent (2%)
of the capital being withdrawn to cover any costs associated with liquidating
Securities to allow the Partnership to pay such withdrawal, along with any other
administrative costs associated with the withdrawal.  This Section 2.07 does not
in any way limit the General Partner's right to reimbursement of costs and
expenses incurred on behalf of the Partnership pursuant to Section 2.02(h).

under this Agreement with ordinary prudence and in a manner reasonable under the
circumstances.  The General Partner shall not be liable to the Partnership or
the Limited Partners for any loss or liability caused by any act, or by the
failure to do any act, unless such loss or liability arises from the General
Partner's intentional misconduct, gross negligence, intentional violation of

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

                                  -----------

                   CAPITAL ACCOUNTS OF PARTNERS; ALLOCATIONS
                   -----------------------------------------

     SECTION 3.01.  Capital Contributions.  Each Partner has made an initial
                    ---------------------                                   
Capital Contribution in cash in the amount set forth opposite such Partner's
name in the Schedule.  After the formation of the Partnership, any new Partner
may make initial Capital Contributions in any amount approved by the General
Partner and shall be bound by the provisions of this Agreement.  Additional
Capital Contributions to the Partnership may be made by Partners only in
accordance with the provisions of Section 3.02.

     SECTION 3.02.  Additional Capital Contributions.  At the beginning of any
                    --------------------------------                          
fiscal quarter of the Partnership, any Partner may make Additional Capital
Contributions to the Partnership as long as such Additional Capital Contribution
is delivered within five days after the first day that begins such quarter and
the General Partner, in its sole discretion has approved such Additional Capital
Contribution.   All Additional Capital Contributions made within five days after
the first day of a fiscal quarter shall be deemed to have been made on the
opening of business on the first day of such fiscal quarter for purposes of
determining an Adjustment Date for purposes of Section 3.04(b).  All Additional
Capital Contributions shall be delivered to the General Partner for the benefit
of the Partnership in cash, certified or cashier's check or Federal funds wire
transfer.

     SECTION 3.03.  Partnership Percentages.  A Partnership Percentage shall be
                    -----------------------                                    
determined for each Partner for each Accounting Period and shall be set forth in
a schedule which shall be filed with the records of the Partnership.

     SECTION 3.04.   Capital Accounts.
                     ---------------- 

     (a) Unless and until the General Partner determines that such would not be
in the best interest of the Partners and the Partnership (in which case Capital
Accounts shall be maintained in accordance with generally accepted accounting
principles), the Partnership shall establish and maintain a capital account
("Capital Account") for each Partner in accordance with Section 704(b) of the
Code and Treasury Regulations Section 1.704-1(b)(2)(iv). If the General Partner
makes the determination provided in the preceding sentence, he shall promptly
give notice to the Partners of such decision, prior to taking any action
hereunder, with such notice to include a description of the proposed change and
its consequences.  Except as provided in, Section 3.04(b) and otherwise by this
Agreement, the Capital Account balance of each Partner shall be credited
(increased) by (i) the 

                                      11
<PAGE>
 
amount of money contributed by such Partner to the capital of the Partnership,
(ii) the fair market value of property contributed by such Partner to the
capital of the Partnership (net of liabilities secured by such property that the
Partnership assumes or takes subject to), and (iii) such Partner's allocable
share of Partnership income and gain (or items thereof) as determined for
Capital Account purposes in accordance with Regulations Section 1.704-
1(b)(2)(iv), including income and gain exempt from federal taxation, and the
Capital Account balance of each Partner shall be debited (decreased) by (i) the
amount of cash distributed to such Partner, (ii) the fair market value of
property distributed to such Partner (net of liabilities secured by such
property which the Partner assumes or takes subject to), and (iii) of such
Partner's share of Partnership losses, depreciation and other deductions, as
determined for Capital Account purposes in accordance with Regulations Section
1.704-1(b)(2)(iv), including such Partner's share of expenditures of the
Partnership described in Section 705(a)(2)(B) of the Code. Notwithstanding the
foregoing, a Partner's Capital Account shall not be adjusted to reflect gain or
loss attributable to the disposition of property contributed by such Partner to
the extent such Partner's Capital Account reflected such inherent gain or loss
in the property on the date of its contribution to the Partnership.

     (b) On the opening of business on any Adjustment Date, the Capital Accounts
of all the Partners shall be adjusted to reflect the manner in which the
unrealized income, gain, loss and deduction inherent in all the Partnership's
property (that has not previously been reflected in the Capital Accounts) would
be allocated among the Partners if there were a taxable disposition of all such
property on such Adjustment Date.  "Adjustment Date" means the effective day (i)
of a distribution of cash and/or property to a Partner in complete or partial
liquidation of such Partner's interest in the Partnership (including
distributions made pursuant to Sections 4.01 and 4.02 hereof); (ii) of a
distribution in liquidation of the Partnership; (iii) the admission to the
Partnership of one or more Limited Partners pursuant to Section 5.01 hereof;
(iv) of any other non-pro rata contribution to or distribution from the
Partnership, including, without limitation, Additional Capital Contributions; or
(v) of the day after the last day of the Fiscal Year.

     SECTION 3.05.  Deficit Capital Account Balances.  Upon liquidation of the
                    --------------------------------                          
Partnership, no Limited Partner with a deficit balance in its Capital Account
shall have any obligation to restore such deficit balance, or to make any
contribution to the capital of the Partnership, except to the extent such
Limited Partner is personally liable to make contributions to the capital of the
Partnership pursuant to Section 1.04 of this Agreement.  Upon liquidation of the
partnership, the General Partner shall be obligated to contribute to the capital
of the Partnership within ninety (90) days after the date of such liquidation an
amount equal to his deficit Capital Account balance which amount shall be paid
to the creditors of the Partnership or distributed to the other Partners in
accordance with their positive Capital Account balances.

     SECTION 3.06.  Allocation of Net Profits  and Net Loss.
                    ----------------------------------------

     (a) Net Profits and Net Losses for each Accounting Period from the
     operations of the Partnership shall be determined in accordance with the
     method of accounting and books and records of the Partnership.  Except as
     provided in Sections 3.06(b), (c) and 

                                      12
<PAGE>
 
     (d) and 3.07, Net Profits and Net Losses attributable to each Accounting
     Period shall be allocated among the Partners as follows:

          (i) First, each Partner shall preliminarily be allocated Net Profits
          and Net Losses during the Accounting Period, pro rata in accordance
          with their Partnership Percentages for such Accounting Period; and

          (ii  Second, notwithstanding Section 3.06(a)(i), at the end of each
          Fiscal Year, after giving effect to the allocations provided for in
          Section 3.06(a)(i), 20% of the amount, if any, by which Net Profits
          for each Accounting Period in such Fiscal Year exceed Net Losses for
          each accounting period in such Fiscal Year shall be reallocated to the
          General Partner.
 
     (b) Notwithstanding anything to the contrary contained herein, items of
income, gain, loss and deduction with respect to an adjustment to the Partners'
Capital Accounts pursuant to Section 3.04(b) to reflect a revaluation of the
property of the Partnership shall be allocated among the Partners so as to take
account of the adjustments to the Partner's Capital Accounts as required in
Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(g), as
currently in effect.

     (c) In accordance with Code Sections 704(b), 704(c) and the Regulations
thereunder, income, gain, loss and deduction with respect to (i) any property
contributed to the capital of the Partnership, and (ii) all property owned by
the Partnership on each Adjustment Date, shall, solely for tax purposes, be
allocated among the Partners so as to take account of any variation between the
adjusted basis of such property to the Partnership for federal income tax
purposes and its value on, as the case may be, the date of contribution or the
Adjustment Date.

     (d) For income tax purposes, allocations of income or loss (and items
thereof) shall be made in accordance with the foregoing allocations of income
and loss for financial purposes.

     (e) As between a Partner who has transferred all or part of its interest in
the Partnership and its transferee, all items of income, gain, deduction and
loss, for any year shall be apportioned on the basis of the number of days in
each such year that each was the holder of such interest (making adjustments
necessary to comply with the provisions of Section 706(d)(2) of the Code),
without regard to the results of the Partnership's operations during the period
before and after the date of such transfer, provided that if the General Partner
in its sole discretion so determines a special closing of the books shall be had
as of the effective date of such transfer and the apportionment of items of
income and gain, and deduction and loss, shall be made on the basis of actual
operating results.

     SECTION 3.07.  Qualified Income Offset Provision.  Notwithstanding anything
                    ---------------------------------                           
else to the contrary contained herein, to the extent that the allocation of any
loss or deduction would cause the deficit Capital Account balance of any Partner
to exceed the dollar amount that such Partner is obligated to restore upon
liquidation of the Partnership as of the end of the Partnership's taxable year

                                      13
<PAGE>
 
to which such allocation relates, such Partner will not be allocated a loss or
deduction which will cause or increase a deficit balance in such Partner's
Capital Account in excess of such amount.  For purposes of this subsection, the
Capital Account of each Partner shall be reduced (a) for any distributions that,
as of the end of such year, reasonably are expected to be made to such Partner
to the extent they exceed offsetting increases to such Partner's Capital Account
that reasonably are expected to occur during (or prior to) the Partnership
taxable years in which such distributions reasonably are expected to be made,
(b) adjustments that as of the end of such year reasonably are expected to be
made for depletion adjustments, and (c) allocations that, as of the end of such
year, reasonably are expected to be made pursuant to Code Section 704(e)(2)
(dealing with family partnerships), Code Section 706(d) (dealing with changes in
Partners' interests) and Treasury Regulation Section 1.751-1 (dealing with
unrealized receivables and inventory items), all as described in Treasury
Regulation Section 1.704-1(b)(2)(ii)(d). A Partner who unexpectedly receives an
adjustment, allocation or distribution described immediately above which causes
or increases a deficit balance in such Partner's Capital Account (in excess of
any dollar amount of such deficit balance that such Partner is obligated to
restore upon liquidation, as of the end of the Partnership's taxable year to
which such allocation relates) will be allocated items of income and gain in an
amount and manner sufficient to eliminate such deficit balance as quickly as
possible.

     To the extent this Section 3.07 prevents the allocation of a deduction or
loss to a Partner, such deduction or loss shall be allocated between the
Partners in accordance with their interests in the Partnership as determined
under Treasury Regulation Section 1.704-1(b)(3).

     SECTION 4.02.  Withdrawals.  Should any Limited Partner desire to withdraw
                    -----------

to Article VII hereof), other than the distributions contemplated by Section
4.01 hereof, such Limited Partner or Partners shall notify the General Partner
in writing of such intent no later than thirty (30) days before the end of the
Fiscal Year.  Any such withdrawal may only be effective as of the end of a
Fiscal Year.  All such withdrawals from the Capital Accounts of the withdrawing
Limited Partner or Partners shall be paid in cash or, at the sole option of the

with this Agreement to the withdrawing Limited Partner or Partners by the
Partnership as soon as reasonably practicable after the books of the Partnership

Section 3.06(a)(ii), and may make a payment in partial satisfaction of the
amount that the Limited Partner's seeks to withdraw, before the books are closed
and the Partnership's information tax returns are completed for such Fiscal
Year. The General Partner may, in its sole discretion, permit a Limited Partner
to withdraw any portion of the positive balance of his Capital Account as
permitted in this Section 4.02 at the end of each fiscal quarter of the
Partnership in the case of special circumstances. However, any such withdrawal
shall comply in all respects with the provisions of this Agreement applicable to
annual withdrawals of capital specified in this Section 4.02.

excess together with interest thereon from the date of  receipt of such excess
to the date of repayment at the prime or base rate of interest announced from
time to time by NationsBank of Texas, N.A., or its successor.

the terms and provisions of this Agreement, subject only to the condition that
each such new Limited Partner shall execute an appropriate amendment or
supplement to this Agreement pursuant to which he agrees to be bound by the

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

     (a) Should the General Partner desire to withdraw from the Partnership, he
shall notify the Limited Partners of such intent prior to the end of the then-
current Fiscal Year with his withdrawal to be effective on and as of midnight on
December 31 of such Fiscal Year.  The withdrawal of the General Partner shall
dissolve the Partnership unless prior to the effective date of such withdrawal
the Limited Partners owning Partnership interests representing a majority of
Partnership Percentages shall have selected a successor general partner and such
person, firm, corporation, partnership or other entity who shall have been
admitted as a General Partner, who shall 

                                      15
<PAGE>
 
have entered into an amendment to this Agreement assuming the responsibilities
of the General Partner hereunder and who shall have received a Capital Account,
by contribution or transfer of interest, in an amount approved by Limited
Partners owning Partnership interests representing a majority of Partnership
Percentages, in which case the Partnership shall not be dissolved. Subject to
Sections 1.04 and 6.03, upon withdrawal, the General Partner shall be entitled
to receive his positive Capital Account balance (as adjusted pursuant to Section
3.04 hereof as the same is shown in the Partnership's books and records) as of
the end of such Fiscal Year, not later than the tenth day following the day the
books of the Partnership are closed and the Partnership's tax return for such
Fiscal Year is completed. No approval or consent of any Limited Partner shall be
required for the withdrawal of such incumbent General Partner, whether or not
such withdrawal ultimately results in termination and liquidation of the
Partnership.

     (b) The withdrawal of the incumbent General Partner, without due succession
of another General Partner, shall cause the Partnership to terminate, and
Limited Partners holding Partnership interests representing a majority of
Partnership Percentages may select one or more persons, firms, corporations or
other entities (the "Terminating Party") to wind up the affairs of the
Partnership in due course and discharge the functions exercised by the General
Partner under Sections 7.01 and 7.02, and the interest in the Partnership of the
General Partner shall continue at the risk of the Partnership business until the
affairs of the Partnership have been wound up in due course.

     (c) In the event of an event of withdrawal (as defined in the Texas Act) of
the General Partner, other than his or its removal or voluntary withdrawal
provided for above, which results in the termination and liquidation of the
Partnership, the interest in the Partnership of such General Partner shall
continue at the risk of Partnership business until the affairs of the
Partnership have been wound up in due course in accordance with Sections 7.01
and 7.02 hereof, and his or its legal representative shall be entitled to
receive the positive balance of his or its Capital Account in accordance with
Sections 7.01 and 7.02 hereof, except as provided in Sections 1.04 and 6.03
hereof.

     SECTION 6.02.  Withdrawal, Death, etc., of Limited Partner.
                    ------------------------------------------- 

     (a) Except as otherwise provided in Sections 2.06 and 2.10 hereof, should a
Limited Partner or Limited Partners desire to withdraw from the Partnership, it
or they shall notify the General Partner of such intent no later than thirty
days before the end of the then current Fiscal Year of  its or their withdrawal
to be effective on and as of midnight on the last day of such Fiscal Year,
unless the Partnership is terminated earlier.  Except as provided in Section
6.03, the Limited Partner shall be entitled to receive the positive balance of
his Capital Account (as adjusted pursuant to Section 3.04 hereof) as the same is
shown on the Partnership's books and records as of the effective day of such
withdrawal.  The Capital Accounts of the withdrawing Limited Partner shall be
paid in cash or, at the sole option of the General Partner, by distribution of
Partnership property valued in accordance with this Agreement to the withdrawing
Limited Partner by the Partnership as soon as reasonably practicable after the
books of the Partnership are closed with respect to such Fiscal Year and the
Partnership's information tax return for such Fiscal Year has been prepared.
The  General Partner may, at its sole option, estimate the withdrawing Limited
Partner's Capital Account as of the 

                                      16

end of the Fiscal Year, and may make a payment in partial satisfaction of the
Capital Account of the withdrawing the Limited Partner, before the books are
closed and the Partnership's information tax returns are completed for such
Fiscal Year.

     (b) The withdrawal, liquidation, death or insanity of a Limited Partner
shall not dissolve the Partnership.

     (c) In the event of the liquidation, death or insanity of a Limited
Partner, the positive Capital Account balance (as adjusted pursuant to Section
3.04 hereof) of such Limited Partner shall be paid to the legal representative
of such liquidated, deceased or insane Limited Partner following the close of
the Fiscal Year in accordance with the provisions of Section 6.02(a) as if such
deceased or insane Limited Partner had voluntarily withdrawn from the
Partnership, except as provided in Section 6.03 hereof.  In the event of the
liquidation, death or insanity of a Limited Partner, the legal representatives
of such Limited Partner may, with the written approval of the General Partner,
continue as a Limited Partner after the end of the Fiscal Year during which such
event occurred.  The interest of a Limited Partner who dies or becomes insane,
or the interest of the legal representatives of such Limited Partner, shall not
after the end of such Fiscal Year be included as an asset of the Partnership nor
included in calculating Partnership Percentages or a majority of Partnership
Percentages of the Limited Partners under Sections 6.01, 7.01 or 10.03;

     Texas Act) with respect to a General Partner; or

          (v) the date upon which the Partnership is terminated under Section
     7.02(c). For purposes of this Agreement, bankruptcy shall be deemed to have
     occurred when the party in question files a petition under any section or
     chapter of the Federal Bankruptcy Code, as amended, or an order for relief
     under Title 11 of the United States Code Annotated is entered against it,
     and insolvency shall be deemed to have occurred when the party in question
     admits in writing that its assets are insufficient to pay its liabilities
     as they mature.

     (b) Upon the occurrence of any event set forth in subparagraph (iv) of
paragraph (a) above with respect to a General Partner, the business of the
Partnership shall be continued pursuant to the provisions of this Agreement if
there (i) remains at least one General Partner, or (ii) is no remaining General
Partner, the Limited Partners unanimously shall elect a new General Partner in

a majority of Partnership Percentages if the termination results from the
circumstance described in Section 7.01 (a)(iv) above) shall wind-up the affairs
of the Partnership, sell its property and assets for cash at the highest price
reasonably obtainable and distribute the proceeds in accordance with Section
7.02 in liquidation of the Partnership.

     SECTION 7.02.  Termination and Liquidation.
                    --------------------------- 

     (a) Upon liquidation (as defined in Section 7.02(c) hereof) of the
Partnership, the assets of the Partnership shall be distributed as soon as
practicable after the date of such liquidation or the end of the Partnership's
taxable year in which the liquidation occurs and shall be applied in the
following order of priority:

          (i) to the payment of debts and liabilities of the Partnership
     (including amounts owed to Partners or former Partners);

                                      18
<PAGE>
 
          (ii) unless inconsistent with Treasury Regulation Section 1.704-
     1(b)(2)(ii)(b), or any successor provision, to set up any reserves which
     the General Partner reasonably determines to be necessary for contingent or
     unforeseen liabilities or obligations of the Partnership arising out of or
     in connection with the business of the Partnership; and

          (iii)  after all Capital Account adjustments for the Partnership's
     taxable year in which the liquidation occurs (including without limitation
     adjustments required under Treasury Regulation Section 1.704-
     1(b)(2)(iv)(e), relating to distributions in kind), to the Partners in

in the Partnership is to be liquidated, liquidating distributions shall be made
in accordance with the positive Capital Account balance of such Partner, as
determined after taking into account all Capital Account adjustments (including
Section 3.04 hereof) for the Partnership's taxable year during which such
liquidation occurs.  Where a Partner's interest is to be liquidated by a series
of distributions, such Partner's interest shall not be considered liquidated
until the final distribution has been made.  For purposes of this Section 7.03,
a liquidation of a Partner's interest in the Partnership means the termination
of the Partner's entire interest in the Partnership by means of a distribution
or series of distributions to the Partner by the Partnership.  Where a Partner's
interest is to be liquidated by a series of distributions, the interest shall

                           VALUATION AND ALLOCATION
                           ------------------------

Participating Trust and shall reflect their respective interests in the Pooled
Trust by showing the number of Investment Units which have been allocated to the
account of each Participating Trust.

     Sec. 3.2   Allocation of Contributions.  As of the first Valuation Date
                ---------------------------                                 
following a transfer of assets of a Participating Trust to the Pooled Trust

account so that the total value of the Investment Units allocated to each
account is not changed by the adjustments.

     Sec. 3.5   Valuation Criteria.  The Trustee shall utilize the following
                ------------------                                          
criteria in valuing the Pooled Trust:

                (a)  The value of an equity or debt security listed on a 
     national securities exchange is the reported price of the last sale made on
     the Valuation Date. If no sales on the Valuation Date are reported, the
     value is the last reported sales price on the last day prior to the
     Valuation Date on which there was a sale.

                (b)  The value of a security not described in paragraph (a) is
     the mean between the last bid and asked prices in the over-the-counter
     market on the Valuation Date. If no bid and asked prices on the Valuation
     Date are available, the last bid and asked prices available for the last
     day prior to the Valuation Date for which bid and asked prices are
     available shall be used. The Trustee may obtain bid and asked prices from
     published sources or from a broker, dealer, investment banker, or quotation
     service. If no bid and asked prices are available, or if the Trustee
     determines that bid and asked prices do not fairly represent the value of
     the security involved, the securities shall be valued pursuant to paragraph
     (d).

                (c)  The value of a United States Savings Bond is the amount
     for which it may be redeemed on the Valuation Date.

                (d)  The value of any other asset is its fair market value on
     the Valuation Date, taking into account unrealized appreciation or
     depreciation and accrued, potential or other expenses. In determining fair
     market value, the Trustee may consult with such persons and consider such
     factors as the Trustee deems appropriate.

The Trustee's valuation of the Pooled Trust shall be conclusive.

                                  INVESTMENTS
                                  -----------

     Sec. 5.1   Investments Allowed.  Subject to the provisions of this Article,
                -------------------                                             
the Trustee shall receive, hold and manage the assets in the Pooled Trust and
shall invest and reinvest the principal and income of the Pooled Trust and shall
keep such assets invested, without distinction between principal and income, in

Trust.  The Trustee may, directly or through investment managers and in its sole
discretion, make investments of the funds in the Pooled Trust in property of any
kind, real, personal or mixed, and whether tangible or intangible, and the
decision of the Trustee as to whether or not any particular investment is of a
type suitable for purchase by the Pooled Trust shall be conclusive on all
persons.  The Trustee may hold any portion of the Pooled Trust in cash and
uninvested whenever it deems such holding necessary or advisable.

     Sec. 5.2   Investment Restraints Imposed.  The Trustee may not make an
                -----------------------------                              
investment which would if made by the Participating Trust result in loss of
qualification of the Participating Trust for exemption from taxation under
Section 501(a) of the Code or constitute a prohibited transaction under Section
4975 of the Code.  The Trustee may not make an investment prohibited by Sections
10 through 14 of the Texas Trust Act.

                                  ARTICLE VI

                                  THE TRUSTEE
                                  -----------

     Sec. 6.1   Accounting.  The Trustee shall maintain adequate books and
                ----------                                                
records reflecting all transactions affecting the Pooled Trust, which books and
records shall be open at all reasonable times to the inspection of the trustee
of a Participating Trust or its authorized representatives and any Employer.
Furthermore, the Trustee shall furnish the trustee of a Participating Trust, at
least annually, statements showing the assets then held in the Pooled Trust on
behalf of such Participating Trust and showing all transactions in the Pooled
Trust since the last preceding statement for the benefit of such Participating
Trust.

     Sec. 6.2   Removal and Resignation.  The Company may remove any person or
                -----------------------                                       
corporation acting as Trustee at any time by sixty (60) days' written notice to
the Trustee unless the Trustee waives the requirement of notice, and the Trustee
may resign at any time by sixty (60) days' written notice to the Company unless
the Company waives the requirement of notice.  In event of the removal or
resignation of 

                                      -5-
<PAGE>
 
the Trustee, the Company shall appoint a successor Trustee, effective
concurrently with the effective date of such removal or resignation, and such
successor Trustee shall furnish to the Company written acceptance of his
appointment.

     Sec. 6.3   Successor Trustee and Transfer of Title.  Neither removal nor
                ---------------------------------------                      
resignation of the Trustee shall constitute termination of the Pooled Trust.
Title to all property and such records or true copies of records as are
necessary to the management of the assets of the Pooled Trust held by the former
Trustee shall vest in any successor Trustee, without the execution or filing of
any further instrument.  A resigning or removed Trustee shall execute all such
instruments and do all such acts as are necessary to vest title in any successor
Trustee. A successor Trustee shall have, exercise and enjoy all the powers and
authority herein conferred upon its predecessor.  No successor Trustee shall be
obligated to examine the accounts, records and acts of any previous Trustee or
Trustees, and no successor Trustee will in any way be responsible for any action
or omission to act on the part of any previous Trustee.  A corporation resulting
from a merger or consolidation to which any corporate Trustee is a party, or
succeeding to the trust business of any corporate Trustee, or to which
substantially all of the trust assets of any corporate Trustee are transferred,
will succeed to the interests of the Trustee under this Agreement without any
further act or formality, and without the requirement of any notice.

     Sec. 6.4   Reliance by Trustee.  The Trustee may rely upon any notice,
                -------------------                                        
certificate, letter, telegram, or other paper or document believed by it to be
genuine or upon any evidence believed by it to be sufficient, in making any
payment or in taking any action whatsoever hereunder.

     Sec. 6.5   Bonding.  The Trustee shall not be required to furnish any bond
                -------                                                        
or security for the performance of its powers and duties hereunder unless a bond
is a requirement of law which cannot be waived.

     Sec. 6.6   Compensation.  The Trustee shall receive reimbursement for its
                ------------                                                  
reasonable expenses incurred in connection with the administration, management
and investment of the Pooled Trust but shall receive no compensation for its
services as Trustee if the Trustee is a full-time employee of the Company or any
Employer.  Any Trustee who is not a full-time employee of the Company or any
Employer may be paid reasonable compensation commensurate with the services and
responsibilities involved hereunder from time to time.

     Sec. 6.7   Expenses.  The Trustee may employ counsel, brokers or agents and
                --------                                                        
may pay for their services and any other reasonable expenses incurred by the
Trustee from the Pooled Trust.  In the event the Pooled Trust incurs any
expenses which in the Trustee's determination should fairly be charged to the
Investment Units allocated to a Participating Trust and not to the Participating
Trusts as a group, the Trustee shall reduce the Investment Units allocated to
such Participating Trust valued as of the Valuation Date which next follows the
date such expenses were paid, by the number of Investment Units equivalent in
value to the amount of the expenses, and shall not include such expenses in
determinations of value pursuant to Article III.

     Sec. 6.8   Ancillary Trustee.  Whenever and as often as the Trustee deems
                -----------------                                             
such action desirable, it may by written instrument appoint any person or
corporation in any state of the United States to act as ancillary trustee with
respect to any portion of the Pooled Trust assets then held or about to be
acquired on behalf of the Pooled Trust.  Each ancillary trustee shall have such
rights, powers, duties and discretions as are delegated to it by the Trustee,
but shall exercise the same subject to the limitations or further directions of
the Trustee as shall be specified in the instrument evidencing its appointment.
The ancillary trustee may resign or may be removed by the Trustee, as to all or
any portion of the assets so held at any time or from 

                                      -6-
<PAGE>
 
time to time, by written instrument delivered one to the other, and the Trustee
may thereupon appoint another ancillary trustee or successor to whom the assets
shall be transferred, or may itself receive such assets in termination of the
ancillary trusteeship to that extent. Such ancillary trustee shall be
accountable solely to the Trustee and shall be entitled to reasonable
compensation.

     Sec. 6.9   Trustee's Powers.  In addition to powers granted to the Trustee
                ----------------

     vote the same in person or by proxy, may join in any merger,
     reorganization, or capital adjustment, may exercise or sell any conversion,
     subscription or similar rights, and may hold any assets hereunder in the
     name of its nominee or unregistered.

                (b)  The Trustee may sell, convey, exchange, encumber, lease,
     and otherwise deal with and dispose of the assets of the Pooled Trust upon
     such terms and conditions as it deems for the best interest of those
     interested in the Pooled Trust.

                (c)  The Trustee may execute any and all deeds, conveyances,
     leases, transfers, proxies and other documents which it believes necessary
     or advisable in the administration of the Pooled Trust.

                (d)  The Trustee may pay or contest any tax or other 
     governmental charge involving any assets held hereunder or the income
     therefrom and may pay the taxes and expenses thus incurred as an expense of
     the Pooled Trust.

                (e)  The Trustee may enforce rights, obligations or claims and
     in general may protect in any way the interest of the Pooled Trust either
     before or after default. The Trustee may abstain from enforcement of
     rights, obligations or claims and may abandon property held by it, if the
     Trustee considers such action to be in the best interest of the Pooled
     Trust.

                (f)  The Trustee may continue to exercise its powers as 
     Trustee for a reasonable time after the termination of the Pooled Trust
     pursuant to Section 8.1.

                --------------                                             
powers of the Trustee be applicable hereunder, it is also intended that all
provisions of the Texas Trust Act, and any amendments thereto, not inconsistent
with the above enumerated powers or other provisions of this Agreement, shall be
applicable in the administration of the Pooled Trust.

     Sec. 6.11  Reliance on Trustee and Others.  Persons dealing with the
                ------------------------------                           
Trustee and any ancillary trustee are not required to inquire into the authority
of such persons or the propriety of the decisions thereof, and are not required
to investigate the application of assets delivered to the Trustee or ancillary
trustee.

     Sec. 6.12  Number and Appointment of Trustees.  The Board of Directors of

     Sec. 7.1   Voluntary Withdrawal.  A Participating Trust may  withdraw all

or a part of its account balance from the Pooled Trust. The withdrawal will be

receipt by the Trustee of written notice from the trustee of the Participating
Trust. The notice shall specify the amount of the Participating Trust's account
balance to be withdrawn, which may be stated in terms of Investment Units,
percentage of account balance, or a fixed dollar amount. The notice shall by its
terms be irrevocable. As of the effective date of the withdrawal, the Trustee
shall decrease the Participating Trust's account by the amount withdrawn. As

     Sec. 7.3   Procedure Upon Withdrawal.  When the Trustee is required to

forth in Section 3.5.

terminate sooner according to the provision of this Agreement, it will terminate
