General Partner) for any loss, damage, liability, cost or expense (including
reasonable attorneys' fees) arising out of any act or failure to act by such

     an amount up to   the cash distributable to the Partners for such fiscal
     year pursuant to Section 9.1(a) shall first be allocated to the Partners in

following manner and order of priority:

          (a) Net gains shall be allocated as follows:

          in the capital accounts of the Partners shall be allocated to the
          Partners having negative capital account balances in proportion to
          their respective negative capital account balances, until the balances
          of the capital accounts of such Partners equal zero, provided that
          such net gains shall first be allocated in such a manner as to cause
          the negative capital account balances of the Partners to stand in the
          ratio of their respective Percentage Interests;

              (ii) then, gain shall be allocated to the General Partners and the
          Class A Limited Partners to the extent necessary to make the balance
          of their respective capital accounts equal to the amount of the
          outstanding Partner Advances respectively made by or on behalf of such
          Partners (the "Unreturned Partner Advances,");


                                       8

 
              (iii) then, gains shall be allocated to the General Partners and

          Partner's capital account by an amount equal to his Unreturned Partner
          Advances) to equal their respective Unrecovered Contribution Account;

              (iv) then, gains shall be allocated to the Partners in a manner,

          reduced in regard to each General Partner's capital account and each
          Class A Limited Partner's capital account by an amount equal to his
          Unreturned Partner Advances, and as further reduced in regard to each
          General Partner's capital account and each Class A Limited Partner's

          Account) to stand in the ratio of their respective Percentage
          Interests; and

              (v) all remaining gains shall be allocated to the Partners in
          proportion to  their respective Percentage Interests; or

          (b) Net losses shall be allocated as follows:

              (i) first, losses shall be allocated to the Partners having
          positive capital account balances in an amount up to and in proportion
          to their positive capital account balances; provided that if the
          amount of such losses is less than the sum of such positive capital
          account balances of all of the Partners having positive capital
          accounts, such losses shall be allocated as follows: first such losses
          shall be allocated in such a manner as to cause, as nearly as can be,
          the capital account balances of the Partners (as reduced in regard to
          each General Partner's capital account and each Class A Limited
          Partner's capital account by an amount equal to his Unreturned Partner
          Advances, and as further reduced in regard to each General Partner's
          capital account and each Class A Limited Partner's capital account by
          an amount equal to his Unrecovered Contribution Account) to



                                       9

 
          stand in the ratio of their respective Percentage Interests and then
          in proportion to their Percentage Interests until the capital account
          balances (reduced as aforesaid) are equal to zero, and then in such a
          manner as to cause, as nearly as can be, the capital account balances
          of the Partners (as reduced in regard to each General Partner's
          capital account and each Class A Limited Partner's capital account by
          an amount equal to his Unreturned Partner Advances) to equal their
          respective Unrecovered Contribution Account and then to the Partners
          in proportion to their Unrecovered Contribution Account until the
          capital account balances (as reduced in regard to each General
          Partner's capital account and each Class A Limited Partner's capital
          account by an amount equal to his Unreturned Partner Advances) are
          equal to zero and then such losses shall be allocated to the General
          Partners and the Class A Limited Partners in proportion to their
          respective Unreturned Partner Advances;

             (ii) then, losses shall be allocated to the Partners in a manner,
          as nearly as  can be, to cause the negative capital account balances
          of the Partners to stand in the ratio of their respective Percentage
          Interests; and

             (iii) all remaining losses shall be allocated to the Partners in

          and the Class A  Limited Partners in an amount up to and in proportion

          account has been adjusted to reflect the allocation of gains or losses
          under Section 8.2);

Upon making their determination of the Partnership's cash needs, the General
Partners shall make a written Cash Call (herein so called) upon the General
Partners and Class A Limited Partners, specifying therein the amount of funds
needed by the Partnership.  Within thirty (30) days after receipt of the Cash
Call, each of the General Partners and Class A Limited Partners shall contribute
to the Partnership his pro rata share (based upon his Percentage Interest in
relation to the Percentage Interests of the General Partners and all Class A
Limited Partners) of the amount specified in the Cash Call.  Such amounts
required to be funded by the General Partners and Class A Limited Partners are
referred to herein as "Partner Advances".  Partner Advances shall be mandatory,

after receipt of a Cash Call, one or more of the other General Partners and
Class A Limited Partners (the "Contributing Partners") shall have the right (but
not the obligation) to advance directly to the Partnership, the Partner Advance
which was to be made by the Non-Contributing Partner.  Such amount so advanced
by the Contributing Partners shall be deemed a Default Loan (herein so called)
to the Non-Contributing Partner, and a Partner Advance from the Non-Contributing
Partner to the Partnership.  If Contributing Partners tender Default Loans in an
amount in excess of the required Partner Advance, the General Partners shall
accept Default Loans on a pro rata (or other reasonable) basis, and shall return
all excess funds.

Partner to the Contributing Partners, (ii) shall have a term of one (1) year f
rom the date made and (iii) shall bear interest at the annual rate of four
percentage points over the short-term prime lending rate at Summit Community
Bank, N.A., prevailing at the time of the loan, but in no event higher than the
maximum rate permitted by Texas law to be charged at the time such loan is made.
Default Loans shall be automatically secured by the Non-Contributing Partner's
interest in the Partnership, and each General Partner shall be fully authorized
and empowered (pursuant to the power of attorney granted in Section 19.1 hereof)
to execute and deliver in the name of the Non-Contributing Partner, notes,
security agreements


                                      14

 
and, financing statements and/or other documents as may be necessary or
convenient to evidence or secure any Default Loans.  While any Default Loan is
outstanding, all distributions to which the Non-Contributing Partner would have
been entitled shall instead be paid to the Contributing Partner(s) and credited
against accrued interest first and then to the principal balance of the Default
Loan until such Default Loan has been paid in full.

             either Summit Bancshares, Inc. or Summit Community Bank, N.A.; and

                (iii) any Transfer of the Partnership interest of a deceased or
             incapacitated Limited Partner to his executors, administrators or
             legal representatives or by any of such persons to accomplish any
             Transfer described under clause (ii) above (and as used in this
             Section XIII, "transferee" shall include such persons).

However, (A) the effectiveness of any of the aforesaid permitted transfers may
be conditioned, in the discretion of the General Partners, upon receipt by the
Partnership of an opinion (the cost of which shall be borne by the transferor),
satisfactory in form and substance to the General Partners, to the effect that
such transaction will not violate the Securities Act of 1933 (the "Securities
Act") or any other applicable securities laws, and (B) no Transfer shall be
permitted if, in the reasonable opinion of counsel to the Partnership (which may
be secured by the General Partners, in their discretion, at the expense of the
Partnership), the Partnership's continued tax status as a


                                      16

 
partnership for federal income tax purposes would be jeopardized by such
Transfer.

     13.3.   The following Transfers by General Partners are permitted:
     -----                                                             

                (i) Each General Partner may Transfer all or any part of its
             Partnership interest to an affiliate (as defined below) of such
             General Partner, and any such transferee of such General Partner's
             interest shall have the right to be admitted to the Partnership as
             a substituted General Partner; provided, however, that: (a) a
             General Partner may not make any such Transfer of its entire
             interest in the Partnership, unless the new general partner has at
             the time of such assignment or transfer a net worth of at least
             Three Hundred Thousand Dollars ($300,000.00), as evidenced by a
             financial statement of the kind that would be used by him (it) in
             dealing with federally chartered banks and similar financial
             institutions and (b) no Transfer of all or any portion of a General
             Partner's interest shall be made to any person (or entity), if such
             person (or entity) is a Tax Exempt Entity.

                (ii) The term "affiliate" used in (i) above means IDI or an
             employee of IDI (or such employee's immediate family) or Summit
             Bancshares, Inc. or any subsidiary or affiliated entity of either
             Summit Bancshares, Inc. or Summit Community Bank, N.A.

                (iii) A General Partner may Transfer all or any part of its
             interest in accordance with the right of first refusal procedures
             set forth in Section 13.4 below.

Notwithstanding the foregoing provisions of this Section 13.3, no General
Partner may Transfer its interest in the Partnership in a manner which would
constitute an event of default under any loan secured by a lien on the Project.

     13.4.   In the event a Limited Partner desires to make a Transfer in
     -----                                                               
accordance with Section 13.2(i) or a General Partner desires to make a Transfer
in accordance with Section 13.3(iii), such Partner shall first notify all other
Partners in writing of the terms of the proposed Transfer.  The other Partners
shall have a right of first refusal exercisable within sixty (60) days after
such notice to acquire such interest in such proportions


                                      17

 
as the other Partners shall mutually agree (or if they cannot agree, then in the
ratio that their respective Percentage Interests bear to one another) . In the
event that the other Partners have not exercised the right of first refusal
granted hereunder and tendered payment of the purchase price within the period
such right may be exercised, such interest may be transferred by the Partner in
accordance with the terms presented to the other Partners.

     13.5.   Notwithstanding anything herein to the contrary, no Partner shall
     -----                                                                    
have the right to Transfer all or part of his or its Partnership interest to any
person if after such Transfer either the Partner (but only if such Partner
continues to hold an interest in the Partnership) or the transferee would hold a
Partnership interest of less than one percent (1%) in the Partnership.

     13.6.   Notwithstanding anything seemingly to the contrary contained in
     -----                                                                  
Section 13.2, no transferee of all or part of the Partnership interest of any
Limited Partner shall have the right to become a substitute Limited Partner,
unless:

            (a) his transferee has stated such intention in the instrument of
     assignment;

            (b) the transferee has executed an instrument reasonably
     satisfactory to the General Partners accepting and adopting the terms and
     provisions of this Agreement;

            (c) the transferor or transferee has paid any reasonable expenses
     in connection with the admission of the transferee as a Limited Partner;
     and

            (d) in the case of an assignee or transferee who is not otherwise a
     Partner, the General Partners consent to such person's becoming a
     substitute Limited Partner (in the sole, absolute and unfettered discretion
     of the General Partners).

     13.7.  If a General Partner should acquire an interest as a Limited
     -----                                                               
Partner, such party shall, with respect to such interest, enjoy all of the
benefits and be subject to all of the obligations and duties of a Limited
Partner to the extent of such interest.

     13.8.  In the event of a Transfer of all or part of the interest of  a
     -----                                                                  
Partner in the Partnership, at the request of the transferee, the General
Partners shall cause the Partnership to elect, pursuant to Section 754 of the
Code, or the corresponding provision of subsequent law, to adjust the basis of
the Partnership property as provided by Sections 734 and 743 of the Code.


                                      18

 
     13.9. Unless otherwise agreed between the transferor and the transferee and
     -----                                                                      
to the extent consistent with the Code and any applicable rules and regulations
thereunder, upon the  Transfer of all or any part of the interest of a Partner
as hereinabove provided, the net income, net losses, net gains and credits
attributable to the interest so transferred shall be allocated between the
transferor and the transferee as of the date set forth in the instrument of
Transfer, and such allocation shall be based upon the number of days during the
applicable fiscal year of the Partnership that the interest so transferred was
held by each of them, without regard to the results of the Partnership
activities during the period in which each was the holder; provided, however,
that net gains or net losses on the sale of the Project shall be allocated to
the holder of record of the interest on the date of sale.  To the extent the
foregoing allocations are inconsistent with the Code and any applicable rules
and regulations thereunder, the allocations will be modified to the extent
required to insure compliance with such rules and regulations thereunder.
Distributions shall be made to the holder of record of the interest on the date
of distribution.
