Gentlemen:

     The undersigned is the holder of a warrant entitling the undersigned to
purchase 11,111 shares of Series B Convertible Preferred Stock, $.01 par value
(the "Series B Preferred"), of Catalog.com, Inc. (the "Company") on the terms
and conditions set forth in the Preferred Stock Purchase Warrant, No. B-001,
dated August 25, 1999 (the "Warrant").  This letter confirms the agreement
between the Company and undersigned that the terms of the Warrant are hereby
amended as follows:

1.   The twelfth line of paragraph 2.1 is amended by adding the phrase "stock
split," immediately after the word "such" and immediately before the word
"reorganization."

2.   The following new paragraph 9 is added immediately after paragraph 8:

          9.   Exercise Upon Completion of the Initial Public Offering by the
     Company. If at any time the Company shall effect a firm commitment
     underwritten public offering of shares of Company's common stock, $.01 par
     value (the "Common Stock") (i) in which the aggregate price paid for such
     shares by the public (prior to deduction of underwriting commissions and
     expenses) is at least $8,000,000 and (ii) which results in (a) the market
     equity capitalization of the Company being equal to, or in excess of,
     $35,000,000 and (b) the listing of the Company's Common Stock on a national
     securities exchange or on The Nasdaq National Market System, then effective
     upon the closing of the sale of such shares by the Company pursuant to such
     public offering (the "Closing Date"), this Warrant shall not be exercised
     for the purchase of shares of Series B Preferred, but may be exercised only
     for the purchase of shares of Common Stock. Upon the Closing Date, the
     number of shares of Common Stock issuable upon the exercise of this Warrant
     pursuant to the terms hereof will be 11,111, and the purchase price of such
     Common Stock will be $9.00 per share of Common Stock, subject to the
     provisions of paragraph 2 of this Warrant as if paragraph 2 referred to
     Common Stock rather than Series B Preferred. Upon the Closing Date, the
     Company shall keep available a sufficient number of shares of Common Stock
     to satisfy the requirements of this Warrant.

     The Warrant is amended and modified only to the extent specifically amended
and modified by this letter agreement, and none of the other terms, conditions
or provisions of the Warrant are amended or modified by this Amendment, except
as necessary to conform to the terms of paragraph 9 above.  The Warrant, as
amended and modified by this Amendment, shall remain in full force and effect.

shall have the right, but never the obligation, to purchase all, but not less
than all, of any Limited Partner's interest in the Partnership as of the end of
any fiscal quarter.  In order to exercise the option herein granted, the General
Partner or the Partnership must notify the affected Limited Partner of its
intent to purchase at least ten days before the last day of the fiscal quarter,
which shall be the effective date of the purchase. The purchase price for the
limited partnership interest being acquired shall be equal to the selling
Limited Partner's Capital Account (as adjusted pursuant to Section 3.04 hereof)
as of the close of business on the last day of the fiscal quarter.  The General
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).

                     ---------------------------
agrees to use its reasonable  efforts in connection with the purposes and
objects of the Partnership and shall  devote to such purposes and objects such
time and activity during normal business days and hours as may be reasonably
necessary, in its reasonable discretion, for the  management of the affairs of
the Partnership; provided, however, that nothing contained in this Section 2.04
                 --------  -------
shall preclude the General Partner from acting as a director, officer, agent or

The TMP shall comply with the requirements of Sections 6221 through 6232 of the
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
Section 6231(a)(3) of the Code and regulations promulgated thereunder) at the
Partnership level.

     (d) If any administrative proceeding contemplated under Section 6223 of the

their treatment of any

                                       8
<PAGE>

Partnership item on their federal income tax return which is or may be
inconsistent with the treatment of that item on the Partnership's return.

     (e) Any Partner who enters into a settlement agreement with the Secretary
of the Treasury with respect to Partnership items shall notify the other
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
to file such a suit, such other Partner shall notify all Partners of such
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 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
                     ----------
Cardinal Investment Company, Inc. and, in exchange therefor, the Partnership
shall pay to Cardinal a portion of the management fee provided in Section 2.07
below.

     SECTION 2.07.   Compensation.   The General Partner shall charge a
                     ------------

Partnership (such valuation to be determined in good faith by the General
Partner).  Such management fee shall be accrued against the Capital Accounts of
the Partners of the Partnership at the beginning 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 beginning of each fiscal quarter.  If a Limited Partner
withdraws capital at a time other than the beginning 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).

     SECTION 2.08.   Liability.  The General Partner shall perform his duties
                     ---------

<PAGE>

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 applicable law, or fraud.
The General Partner shall be entitled to deal with his Affiliates in the
performance of his duties and obligations under this Agreement, unless expressly
prohibited therefrom by a specific provision hereof.

     SECTION 2.09.   Removal of General Partner.  Partners owning Partnership
                     --------------------------
interests representing ninety percent (90%) of the Partnership Percentages shall
be entitled to remove the General Partner at any time and for any reason, with
or without cause.  Upon the removal of the General Partner, the Partnership
shall be terminated.

     SECTION 2.10.   Power of Attorney.
                     -----------------

     (a)  Each Limited Partner hereby irrevocably severally appoints and
constitutes the General Partner, his successors and assigns hereunder, as its
true and lawful attorney-in-fact, with full power and authority, on its behalf
and in its name, to execute, acknowledge, swear to, deliver and, where
appropriate, file in such offices and places as may be required by law:

          (i)  any amendment to this Agreement, and as contemplated by Section
     2.02(e) hereof, the Certificate of Limited Partnership, required by a
     change in the name of the Partnership, a change of the name or address of
     the registered agent of the Partnership, the withdrawal of the General
     Partner, or the admission of any party to the Partnership as a General
     Partner, if such admission is in compliance with the applicable provisions
     hereof; and

          (ii) any amendment to this Agreement upon compliance with Section
     10.03.

     (b)  The power of attorney granted by the Limited Partners to the General
Partner under Paragraph (a) above is a special power coupled with an interest
and is irrevocable, and may be exercised by any party who at the time of
exercise is a General Partner of the Partnership.  Such power of attorney shall
survive the death or legal incapacity of a Limited Partner and any assignment or
abandonment of all or any portion of his interest in the Partnership or his
withdrawal from the Partnership.

     SECTION 2.11.   Section 754 Election.  Upon election by the General Partner
                     --------------------

other action as may be necessary to make the election provided by Section 754 of
the Internal Revenue Code of 1986, as amended.

                   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 at the beginning of a Fiscal Year 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 Year 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 Fiscal Year
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 Year shall be deemed to have been made on
the opening of business on the first day of such Fiscal Year 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 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

                                      11
<PAGE>

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 (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

                                      12
<PAGE>

         (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
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

                                      13
<PAGE>

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).

                                  ARTICLE IV
                                  ----------

               EARNINGS DISTRIBUTIONS AND WITHDRAWAL OF CAPITAL
               ------------------------------------------------

     SECTION 4.01.  Earnings Distributions.  Unless the General Partner, in its
                    ----------------------
sole discretion, decides otherwise, all available cash for each Fiscal Year from
the operations of the Partnership shall be retained by the Partnership.  The
General Partner may, in its sole discretion,  make such distributions of cash 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 of the end of the Fiscal Year taking into account, inter alia, the amount, if
                                                      ----------
any, of Net Profits that may be allocated to the General Partner pursuant to
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

                                      14
<PAGE>

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
                    -----
distributions pursuant to the terms of this Agreement, which, after a
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

effective at the beginning of any Fiscal Year, one or more new Limited Partners
and determine the terms and conditions thereof, so long as they are identical to
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
terms and provisions hereof.  Admission of one or more new Limited Partners
shall not be a cause for dissolution of the Partnership.  Upon the admission of
one or more new Limited Partners, the Capital Account of each Partner shall be
adjusted as contemplated by Section 3.04 hereof.

     SECTION 6.01.   Withdrawal of General Partner.
                     -----------------------------

     (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.  Upon any such withdrawal due to the inability
of Cardinal Investment Company, Inc. to continue as the General Partner, 2M
Partners, LLC, a Texas limited liability company owned fifty percent (50%) by
James Traweek and fifty percent by Kent McGaughy, agrees that it shall serve as
a successor general partner if approved by Limited Partners owning Partnership
interests representing a majority of Partnership Percentages, and that it shall
assume the responsibilities of the General Partner hereunder and shall receive a
Capital Account, by contribution or transfer of interest, in an amount approved
by such Limited Partners.  Except as set forth in the previous sentence, the
withdrawal of the General Partner shall dissolve the Partnership.  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

                                      15
<PAGE>

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 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.

                                      16
<PAGE>

     (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;
provided, however, in the event the General Partner has approved the continuance
--------
of a Limited Partner's legal representatives as a Partner of the Partnership
pursuant to the preceding sentence, such Partnership Percentages shall be so
included in such calculations.

     SECTION 6.03.   Limitations on Withdrawal of Capital Account; Prorated
                     ------------------------------------------------------
Distributive Share.  The right of any withdrawn, terminated, liquidated,
------------------
deceased or insane Partner or his legal representative to have distributed the
positive balance of such Partner's Capital Account is subject to the reasonable
provision by the General Partner, the successor General Partner or the
Terminating Party, as appropriate, for all Partnership liabilities in accordance
with the Texas Act and for reserves for contingencies, which reserves shall be
held in escrow.  The unused portion of any reserve shall be distributed after
the General Partner shall have determined that the need therefor shall have
ceased.

     SECTION 7.01.   Dissolution and Wind-up of Affairs.
                     ----------------------------------

     (a)  It is the intention of the Partners that the business of the
Partnership be continued by the Partners, or those remaining, pursuant to the
provisions of this Agreement, notwithstanding the occurrence of any event which
would result in a statutory dissolution of the Partnership pursuant to the laws
of the State of Texas, and no Partner shall be released or relieved of any duty
or obligation hereunder by reason thereof; provided, however, that the business
of the Partnership shall be terminated, its affairs wound-up and its property
and assets distributed in liquidation on the earlier to occur of:

          (i)  December 31, 2015;

          (ii) a determination by holders of Partnership interests representing
     a majority of Partnership Percentages that the business of the Partnership
     should be terminated;

          (iii)  the bankruptcy or insolvency of the Partnership;

          (iv)   subject to Section 6.01 hereof and the provisions of paragraph
     (b) below, the occurrence of an event of withdrawal (as defined in the
     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 remains at least one General Partner.

     (c)  As expeditiously as possible following the occurrence of an event
giving rise to a termination of the business of the Partnership, the General
Partner (or a special liquidator who may be appointed by Limited Partners owning
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);

          (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
     accordance with each Partner's positive Capital Account balance.

     (b) For purposes of this Section 7.02, a liquidation of the Partnership
shall occur upon the date upon which the Partnership is terminated under Section
7.01.

     SECTION 7.03.   Liquidation of Partner's Interest.  If a Partner's interest
                     ---------------------------------
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
not be considered as liquidated until the final distribution has been made.

legal representative) to prepare his income tax returns in accordance with the

action, suit or proceeding, whether civil, criminal, administrative,
arbitrative, or investigative, any appeal in such an action, suit or proceeding,

fact that such person was or is serving as a Partnership Functionary in
accordance with the provisions of this

                                      19

against judgments, penalties (including excise and similar taxes), fines,
settlements, and reasonable expenses actually incurred in connection with such
Proceeding, and (ii) pay or reimburse the Partnership Functionary, in advance of
the final disposition of the Proceeding, reasonable expenses incurred in

          (a) The Partners may be given access to various confidential and
proprietary information regarding the Partnership consisting of, but not limited
to, processes, compilations of information, records, pricing techniques, plans
and other confidential information (collectively, the "Confidential
Information") which is owned by the Partnership or the General Partner and
regularly used in the business of the Partnership or the General Partner.  Each
Partner acknowledges that it will be provided with access to the Confidential
Information in exchange for such Partner's promise herein not to disclose such
Confidential Information.  Each Partner further acknowledges and agrees that the
Confidential Information (a) is secret and not generally known; (b) is entrusted
to such Partner only because such Partner is hereby acknowledging its
confidential and secret status; (c) has been developed or acquired by the
Partnership or the General Partner through substantial expenditures of time,
effort and/or money and is used in the business of the Partnership or the
General Partner; (d) gives the Partnership or the General Partner an advantage
over competitors who do not know the Confidential Information; (e) is of such
value and nature as to make it reasonable and necessary to protect and preserve
the confidentiality and secrecy of the Confidential Information; and (f) is a
valuable, special, and unique asset of the Partnership or the General Partner,
the disclosure of which could cause substantial injury and loss of profits and
goodwill to the Partnership or the General Partner.  Such Partner shall not
hereafter use in any way or disclose, in whole or in part, outside the
Partnership any of the Confidential Information, directly or indirectly through
one or more other entities, either while a Partner or at any time thereafter,
except as required by the Partnership or the General Partner or in connection
with a Partner serving as a manager or officer of the Partnership or the General
Partner.  All files, records, documents, information, data and similar items
relating to the business of the Partnership, coming into such Partner's
possession from the Partnership or the General Partner, shall remain the
exclusive property of the Partnership or the General Partner and shall be
promptly delivered to the Partnership upon such Partner's ceasing to be a
Partner in the Partnership.  Each Partner agrees that upon such Partner's
receipt of any subpoena, process, or other request to produce or divulge,
directly or indirectly, any Confidential Information to any Person, such Partner
shall (to the fullest extent not prohibited by applicable law

                                      20
<PAGE>

or by a court order binding on such Partner) promptly notify the Partnership and
the General Partner thereof and promptly deliver a copy of the subpoena,
process, or other request to the Partnership and the General Partner. For this
purpose, such Partner irrevocably nominates and appoints the Partnership and the
General Partner, or either of them acting alone (including any attorney or legal
counsel retained by the Partnership and/or the General Partner), as such
Partner's true and lawful attorney-in-fact, to act in such Partner's name, place
and stead to perform any act that such Partner might perform to defend and
protect against any disclosure of any Confidential Information.

          (b) The Partnership shall have any and all remedies provided at law or
in equity to enforce the provisions of this Section 10.02.  If a Partner (the
"Violating Partner") violates this Section 10.02, then each Partner covenants
and agrees that the General Partner shall be fully authorized and entitled
(without any vote or approval of the Limited Partners) to promptly cause the
Partnership to purchase the Violating Partner's Partnership interest, and each
Partner hereby grants the Partnership such an option (and the General Partner
shall also be fully entitled to remove the Violating Partner from the
Partnership) in exchange solely for an amount equal to (i) the Capital
Contributions made by the Violating Partner less (ii) the aggregate
                                            ----
distributions previously made to the Violating Partner pursuant to this
Agreement.

          (c) The Partners intend that the provisions of this Section 10.02,
including specifically the provisions of Section 10.02(b), shall supersede, and
apply in the event of any conflict with, any and all other provisions of this
Agreement.

permitted assigns of the Partners, (b) shall be governed by, and construed in
accordance with, the laws of the State of Texas without reference to the
conflict of laws principles of any jurisdiction, and (c) this Agreement and any
amendment hereto may be executed in several counterparts with the same effect as
if the parties executing the several counterparts had all executed one
counterpart as of the date and year first above written on this Agreement or on
any amendment to this Agreement; provided, however, that the several
                                 --------  -------
counterparts, in the aggregate, shall have been signed by all of the Partners.

     SECTION 10.04.  Amendments to Partnership Agreement.  The terms and
                     -----------------------------------
provisions of this Agreement may be amended at any time and from time to time
(a) in accordance with Section 2.11 hereof or (b) with the written consent of
Limited Partners holding a majority of Partnership Percentages and the written
consent of the General Partner.

     SECTION 10.05.  Notices.  Each notice relating to this Agreement shall be

in writing and delivered in person or by registered or certified mail, return
receipt requested.  All notices to the Partnership or to the General Partner

All notices addressed to a Limited Partner shall be addressed to such Limited
Partner at the address set forth in the Schedule as then in effect.  Any Partner
may designate a new address by notice to that effect given to the Partnership.
Unless otherwise specifically provided in this

     SECTION 10.06.  Number and Gender of Words.  Whenever in this Agreement the
                     --------------------------
singular number is used, the same shall include the plural, where appropriate,
and vice versa; and words of any gender shall include all other genders where
appropriate.

     SECTION 10.07.  Headings.  The titles of the Articles and the headings of
                     --------
the Sections of this Agreement are for convenience of reference only and are not
to be considered in construing the terms and provisions of this Agreement.

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

inferable from this Agreement, the Texas Act or any other statute or principle
of law, neither the Partners nor any of their Affiliates shall be prohibited or
restricted in any way from investing in or conducting, either directly or
indirectly, and may invest in and/or conduct, either directly or indirectly,
businesses of any nature whatsoever, including the ownership and operation of
businesses or properties similar to or in the same geographical area as those
held by the Partnership.  Any such investment in or conduct of any such business
by a Partner or Affiliate thereof shall not give rise to any claim for an
accounting by the other Partners or the Partnership or any right to claim any
interest therein or the profits therefrom.

     SECTION 10.11.  Spouses as Parties.  The parties hereto agree that, if
                     ------------------
