and agreements of the "INDEMNITOR", "GUARANTOR" and/or "PRINCIPAL" (collectively
referred to herein as "INDEMNITOR") under the Indemnity Agreement, the
Environmental Indemnity Agreement and the other Loan Documents to which Original
Indemnitor is a party, and the Assuming Indemnitor shall be liable and
responsible for each and all of the liabilities of the Indemnitor thereunder,
and shall be substituted in lieu of and in place of the Original Indemnitor, as
fully and completely as if the Assuming Indemnitor had originally executed and
delivered such Loan Documents as the Indemnitor thereunder, including, without
limitation, all of those obligations, agreements and liabilities which would
have, but for the provisions of this Agreement, been the obligations, agreements
and liabilities of the Original Indemnitor, without regard to when such
obligations, agreements and liabilities arise, accrue or have arisen or accrued,
and without regard to the Indemnitor then responsible or liable therefor at the
time of such accrual. From and after the date hereof, the Assuming Indemnitor
further agrees to abide by and be bound by all of the terms of the Loan
Documents having reference to the Indemnitor, all as though each of the Loan
Documents to which the Original Indemnitor is a party had been made, executed,
and delivered by the Assuming Indemnitor as the Indemnitor. From and after the
date hereof, the Assuming Indemnitor hereby agrees to pay, perform, and
discharge each and every obligation of payment and performance of the Indemnitor
under, pursuant to and as set forth in the Loan Documents at the time, in the
manner and otherwise in all respects as therein provided. With respect to the

Loan Documents, or are otherwise delivered by the Lender thereunder at Lender's
sole discretion, to the Assuming Indemnitor's address set forth above.

        6. CONSENT TO CONVEYANCE, ASSUMPTION AND SUBSTITUTION OF INDEMNITOR;
RELEASE OF ORIGINAL OBLIGORS. Subject to the terms and conditions set forth in
this Agreement, Lender consents to: (a) the sale, conveyance, assignment and
transfer of the Property by Original Borrower to Assuming Borrower, subject to
the Mortgage and the other Loan Documents; (b) the assumption by Assuming
Borrower of the Loan and the obligations of Original Borrower under the Loan
Documents; and (c) the assumption by Assuming Indemnitor of the obligations of
the Original Indemnitor under the Loan Documents to which Original Indemnitor is

liability to Lender under any and all of the Loan Documents arising or first
accruing subsequent to the transfer of the Property to Assuming Borrower and the
assumption by Assuming Borrower and Assuming Indemnitor

                                       5
<PAGE>

hereunder. Lender's consent to such transfer and assumption shall, however, not
constitute its consent to any subsequent transfers of the Property. Original
Obligors hereby acknowledge and agree that the foregoing release shall not be
construed to release Original Obligors from any personal liability under the
Note or any of the other Loan Documents for any acts or events occurring or
obligations arising prior to or simultaneously with the closing of the
transaction described herein.

        7. RELEASE AND COVENANT NOT TO SUE. Original Obligors and Assuming

servicer of the Loan, each of their respective predecessors in interest and
successors and assigns, together with the officers, directors, partners,

including, without limitation, matters arising out of or relating to: (a) the
Loan, including, without limitation, its funding, administration and servicing;
(b) the Loan Documents; (c) the Property; (d) any reserve and/or escrow balances
held by Lender or any servicers of the Loan; or (e) the sale, conveyance,
assignment and transfer of the Property except, with respect to any
counter-claims or defenses made by Original Obligors in a proceeding instituted
by any Lender Party, for matters related to claims permitted pursuant to the
immediately following sentence. Original Obligors and Assuming Obligors, on
behalf of themselves and their heirs, successors and assigns, covenant and agree
never to institute or cause to be instituted or continue prosecution of any suit
or other form of action or proceeding of any kind or nature whatsoever against
any of the Lender Parties by reason of or in connection with any of the
foregoing matters, claims or causes of action, except for those claims or causes
of action resulting from any of the Lender Parties' fraud, gross negligence or
willful misconduct.

authority to enter into and carry out the terms of this Agreement and to assume

           (d) This Agreement and the Loan Documents constitute legal, valid and
binding obligations of Assuming Obligors enforceable in accordance with their
respective terms. Neither the entry into nor the assumption and performance of

<PAGE>

agreement or lease by which Assuming Obligors or any property of Assuming
Obligors are bound or any statute, rule or regulation applicable to Assuming
Obligors.

           (e) There is no action, proceeding or investigation pending or, to

financial condition of Assuming Obligors has occurred, and there is not any
pending or, to the knowledge of Assuming Obligors, threatened litigation or
proceedings which might impair to a material extent the business or financial
condition of Assuming Obligors.

           (h) Without limiting the generality of the assumption of the Loan

reaffirm the representations, warranties and covenants set forth in the
Mortgage, the Indemnity Agreement and the Environmental Indemnity Agreement.

           (i) No representation or warranty of Assuming Obligors made in this

material fact necessary in order to make such representations and warranties not
misleading in light of the circumstances under which they are made.

Lists. Assuming Borrower shall immediately notify Lender if Assuming Borrower

nolo contender to, (C) is indicted on or (D) is arraigned and held over on
charges involving money laundering or predicate crimes to money laundering.

        15. ADDITIONAL REPRESENTATIONS, WARRANTIES AND COVENANTS OF ORIGINAL
OBLIGORS. As a condition of this Agreement, Original Obligors represent and
warrant to Lender as follows:

            (a) Original Borrower is a limited partnership duly organized,

terms of this Agreement and to convey the Property and assign the Loan
Documents.

            (c) Each Original Indemnitor is a resident of the State of [Texas]

            (d) This Agreement, the Sales Agreement and all other documents
executed by Original Obligors in connection therewith, constitute legal, valid
and binding obligations of Original Obligors enforceable in accordance with
their respective terms, subject to applicable debtor relief statutes. Neither
the entry into nor the performance of and compliance with this Agreement, the
Sales Agreement and all other documents executed by Original Obligors in
connection therewith has resulted or will result in any violation of, or a
conflict with or a default under, any judgment, decree, order, mortgage,
indenture, contract, agreement or lease by which Original Obligors or any
property of Original Obligors are bound or any statute, rule or regulation
applicable to Original Obligors.

            (e) Original Obligors have not received any written notices from any
governmental entity claiming that Original Obligors or the Property is not
presently in compliance with any laws, ordinances, rules, and regulations
bearing upon the use and operation of the Property, including, without
limitation, any notice relating to zoning laws or building code regulations.

            (f) The Certified Rent Roll provided to Lender of even date
herewith, is a true, complete and accurate summary of all tenant leases ("TENANT
LEASES" or individually a "TENANT LEASE") affecting the Property as of the date
of this Agreement. No rent has been prepaid under any Tenant Lease except rent
for the current month. Each

                                       11
<PAGE>

Tenant Lease has been duly executed and delivered by, and, to the knowledge of
Original Obligors, is a binding obligation of, the respective tenant, and each
Tenant Lease is in full force and effect. Each Tenant Lease represents the
entire agreement between the landlord and the respective tenant and no Tenant
Lease has been terminated, renewed, amended, modified or otherwise changed
without the prior written consent of Lender to the extent required under the
Loan Documents. The tenant under each Tenant Lease has taken possession of and
is in occupancy of the premises therein described and is open for business. Rent
payments have commenced under each Tenant Lease, and all tenant improvements in
such premises and other conditions to occupancy and/or rent commencement have
been completed by Landlord. All obligations of the landlord under the Tenant
Leases have been performed, and no event has occurred and, to the knowledge of
Original Obligors, no condition exists that, with the giving of notice or lapse
of time or both, would constitute a default by Landlord under any Tenant Lease.
There are no offsets or defenses that any tenant has against the full
enforcement of any Tenant Lease by the landlord thereunder. Each Tenant Lease is
fully and freely assignable by the landlord without notice to or the consent of
the tenant thereunder.

            (g) Original Borrower is the current owner of the Property. There
are no pending or, to the knowledge of Original Obligors, threatened suits,
judgments, arbitration proceeding, administrative claims, executions or other
legal or equitable actions or proceedings against Original Obligors or the
Property, or any pending or, to the knowledge of Original Obligors, threatened
condemnation or annexation proceedings affecting the Property, or any agreements
to convey any portion of the Property, or any rights thereto, not disclosed in
this Agreement, including, without limitation to any governmental agency.

            (h) RESERVED

            (i) No representation or warranty of Original Obligors made in this
Agreement contains any untrue statement of material fact or omits to state a
material fact necessary in order to make such representations and warranties not
misleading in light of the circumstances under which they are made.

        16. INCORPORATION OF RECITALS. Each of the Recitals set forth above in
this Agreement are incorporated herein and made a part hereof.

        17. PROPERTY REMAINS AS SECURITY FOR LENDER. All of the Mortgaged
Property as described and defined in the Mortgage shall remain in all respects
subject to the lien, charge or encumbrance of the Mortgage, and, except as
expressly set forth herein, nothing herein contained and nothing done pursuant
hereto shall affect or be construed to release or affect the liability of any
party or parties who may now or hereafter be liable under or on account of the
Note or the Mortgage, nor shall anything herein contained or done in pursuance
hereof affect or be construed to affect any other security for the Note, if any,
held by Lender.

        18. NO WAIVER BY LENDER. Nothing contained herein shall be deemed a
waiver of any of Lender's rights or remedies under any of the Loan Documents, or
under applicable law.

        19. REFERENCES. From and after the date hereof: (a) references in any of
the Loan Documents to any of the other Loan Documents will be deemed to be

deemed to refer to Assuming Borrower; (c) references

                                       12
<PAGE>

in the Indemnity Agreement, Environmental Indemnity Agreement and the other Loan
Documents to the Guarantor, Indemnitor or Principal shall hereafter be deemed to
refer to Assuming Indemnitor; and (d) all references to the term "Loan
Documents" in the Mortgage and Assignment of Rents shall hereinafter refer to
the Loan Documents referred to herein, this Agreement, and all documents
executed in connection with Agreement.

        20. RELATIONSHIP WITH LOAN DOCUMENTS. To the extent that this Agreement
is inconsistent with the Loan Documents, this Agreement will control and the
Loan Documents will be deemed to be amended hereby. Except as amended hereby,
the Loan Documents shall remain unchanged and in full force and effect.

        21. CAPTIONS. The headings to the Sections of this Agreement have been
inserted for convenience of reference only and shall in no way modify or
restrict any provisions hereof or be used to construe any such provisions.

        22. PARTIAL INVALIDITY. If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws, such provision
shall be fully severable, and this Agreement shall be construed and enforced as
if such illegal, invalid or unenforceable provision had never comprised a part
of this Agreement.

        23. ENTIRE AGREEMENT. This Agreement and the documents contemplated to
be executed herewith constitutes the entire agreement among the parties hereto
with respect to the assumption of the Loan and shall not be amended unless such
amendment is in writing and executed by each of the parties. The Agreement
supersedes all prior negotiations regarding the subject matter hereof. This
Agreement and the Loan Documents may not be amended, revised, waived,
discharged, released or terminated orally, but only by a written instrument or
instruments executed by the party against which enforcement of the amendment,
revision, waiver, discharge, release or termination is asserted. Any alleged
amendment, revision, waiver, discharge, release or termination which is not so
documented shall not be effective as to any party.

        24. BINDING EFFECT. This Agreement and the documents contemplated to be
executed in connection herewith shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns; provided,
however, that the foregoing provisions of this Section shall not be deemed to be
a consent by Lender to any further sale, conveyance, assignment or transfer of
the Property by Assuming Borrower.

        25. MULTIPLE COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which, taken
together, will constitute one and the same Agreement.

        26. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State where the Property is located.

        27. EFFECTIVE DATE. This Agreement shall be effective as of the date of
its execution by the parties hereto and thereupon is incorporated into the terms
of the Loan Documents.

provisions of this Agreement.

        29. CUMULATIVE REMEDIES. All remedies contained in this Agreement are
cumulative and Lender shall also have all other remedies provided at law and in
equity or in the Mortgage and other Loan Documents. Such remedies may be pursued
separately, successively or concurrently at the sole subjective direction of
Lender and may be exercised in any order and as often as occasion therefor shall
arise.

        30. CONSTRUCTION. Each party hereto acknowledges that it has
participated in the negotiation of this Agreement and that no provision shall be
construed against or interpreted to the disadvantage of any party. Assuming
Obligors and Original Obligors have had sufficient time to review this
Agreement, have been represented by legal counsel at all times, have entered
into this Agreement voluntarily and without fraud, duress, undue influence or

LENDER, TO THE FULL EXTENT PERMITTED BY LAW, HEREBY KNOWINGLY, INTENTIONALLY AND
VOLUNTARILY, WITH AND UPON THE ADVICE OF COMPETENT COUNSEL, WAIVE, RELINQUISH

                                  ARTICLE III.

                                     CAPITAL

        3.1 INITIAL CAPITAL CONTRIBUTIONS. Upon the execution of this Agreement,
the Partners shall make Initial Capital Contributions to the Partnership of cash
in the amounts set forth opposite their respective names on EXHIBIT D attached
hereto and made a part hereof.

        3.2 ADDITIONAL CAPITAL CONTRIBUTIONS.

            (a) If at any time the General Partner determines that the
Partnership requires funds to close the acquisition of the Property or for
Operating Expenses, or that within ninety (90) days the Partnership will require
funds for Operating Expenses (collectively, "CASH NEEDS"), then the General
Partner shall use reasonable efforts to secure third party or Partner loans to
fulfill such Cash Needs. If such efforts to secure third party or Partner loans
are unsuccessful, the General Partner may send the Limited Partners written
notice ("ADDITIONAL CAPITAL NOTICE") requesting that the Limited Partners,
together with the General Partner, contribute in cash such amounts as are
necessary to satisfy such Cash Needs and describing the purpose for which the
funds are needed. If so requested, the General Partner and each Limited Partner
shall be obligated to make an Additional Capital Contribution equal to the
product of its Residual Percentage and the amount of the Cash Needs. The time
for the payment of any Additional Capital Contribution to the Partnership shall
be determined by the General Partner, but shall in no event be less than ten
(10) days after the delivery of the Additional Capital Notice.

            (b) If the General Partner or a Limited Partner fails to timely
contribute all or any portion of any Additional Capital Contribution required of
such Partner, then such Partner shall be considered a "DELINQUENT PARTNER." The
Partnership may, upon notice to a Delinquent Partner, exercise either one of the
following remedies as its sole remedy:

                (i) permit the non-Delinquent Partner(s) to advance that portion
of the Additional Capital Contribution that is in default as a loan (a "DEFAULT
LOAN") with the following results: (A) the sum thus advanced shall constitute a
loan to the Delinquent Partner; (B) such loan and all accrued unpaid interest
thereon shall be due on demand, or if no demand is made, twelve (12) months
after such advance is made; (C) the loan shall bear interest at the lesser of
twelve percent (12%) per annum or the highest rate permitted by applicable law,
from the date made until the date fully repaid compounding monthly; and (D) all
Partnership distributions and other payments that otherwise would be made to the
Delinquent Partner (whether before or after dissolution of the Partnership)
under this Agreement (including those under Article 6) shall be paid to the
non-Delinquent Partner until the loan and all interest accrued thereon is paid
in full (with all such payments being applied first to accrued and unpaid
interest and then to principal and being deemed to be a distribution or payment
(as may apply) to the Delinquent Partner, and, in turn, a payment by the
Delinquent Partner with respect to the loan from the non-Delinquent Partner); or

                (ii) permit the non-Delinquent Partner to contribute that
portion of the Additional Capital Contribution that is in default as an
Additional Capital Contribution made by the non-Delinquent Partner, in which
case the non-Delinquent Partner shall have its Residual Percentage increased and
the Delinquent Partner shall have its Residual Percentage decreased in the
following manner: (A) the

                                       9
<PAGE>

Residual Percentage of the non-Delinquent Partner immediately following such
Additional Capital Contributions shall be increased by an amount equal to 110% x
A/B, where 'A' equals the amount the non-Delinquent Partner contributed in
respect of the Delinquent Partner's required Additional Capital Contribution,
and `B' equals the sum of all unreturned Capital Contributions previously made
to the Partnership after giving effect to the amounts advanced under this
Section 3.2(b)(ii) on behalf of the Delinquent Partner; and (B) the Residual
Percentage of the Delinquent Partner shall be decreased by the increase of the
non-Delinquent Partner's Residual Percentage.

            (c) The exercise by the Partnership of the remedies set forth in
Section 3.2(b) above shall be determined by the non-Delinquent Partner in its
sole discretion and not by the Delinquent Partners.

            (d) With respect to any efforts by the General Partner to obtain
loans to the Partnership from a third party or a Partner (including the General
Partner), the financing terms must be substantially similar to (or more
favorable than) loans which the Partnership could obtain on a competitive
arms-length basis. If the General Partner is unable to determine whether the
financing terms are competitive on an arms-length basis, the General Partner may
seek a Partnership Vote on the issue, or may seek and rely upon the advice of an
independent expert in financing. If any Partner makes any loan or loans to the
Partnership or advances money on its behalf, the amount of any loan or advance
shall not be treated as a Capital Contribution but shall be treated as a debt
due from the Partnership to such Partner.

        3.3 CAPITAL ACCOUNTS. The Partnership shall establish and maintain on
its books and records for each Partner a capital account (collectively the
"CAPITAL ACCOUNTS") in accordance with Section 1.704-1(b)(2)(iv) of the
Regulations. Subject to the foregoing, each Partner's Capital Account generally
shall be:

            (a) increased by (i) the amount of money contributed by such Partner
to the Partnership, including Partnership liabilities assumed by such Partner;
(ii) the fair market value of property (net of liabilities securing such
property that the Partnership has assumed, or taken subject to, under Section
752 of the Code), or other consideration contributed by such Partner to the
Partnership; and (iii) allocations to such Partner of Net Profits (and items
thereof, including certain tax exempt income) and income and gain described in
Section 1.704-1(b)(2)(iv)(g) of the Regulations; and

            (b) decreased by (i) the amount of money distributed to such Partner
by the Partnership, including such Partner's individual liabilities assumed by
the Partnership; (ii) the fair market value of all property distributed to such
Partner by the Partnership (net of liabilities that such Partner is considered
to assume or take subject to under Section 752 of the Code); and (iii)
allocations to such Partner of Net Losses and deductions, including expenses
described in Section 705(a)(2)(B) of the Code which are not deductible for tax
purposes.

        3.4 INTEREST ON AND WITHDRAWAL OF CAPITAL CONTRIBUTIONS. Neither the
General Partner nor the Limited Partners shall be entitled to receive any
interest on Capital Contributions, nor shall the General Partner or the Limited
Partners be entitled to withdraw or otherwise receive a return of their Capital
Contributions from the Partnership, except pursuant to the terms and conditions
of this Agreement. No Partner shall be required to contribute or lend any cash
or property to the Partnership to enable the Partnership to return any Partner's
Capital Contributions.

        3.5 RESIGNATION; REDEMPTION. Except as otherwise expressly permitted by
this Agreement, no Partner may resign or withdraw from the Partnership without
Approval by Partnership Vote. A Partner's interest in the Partnership may not be
redeemed or purchased by the Partnership without prior Approval by Partnership
Vote.

                                       10

        3.6 TRANSFERS. If any interest in the Partnership is Transferred in
accordance with the terms of this Agreement, the Transferee will succeed to the
Capital Account of the Transferor to the extent it relates to the Transferred
interest.

                                  ARTICLE IV.

                                   MANAGEMENT

        4.1 GENERAL POWERS OF GENERAL PARTNER. Except as provided in Section 4.3

with all rights and powers generally conferred by applicable law or necessary,
advisable or consistent in connection therewith, including without limitation to
cause the Partnership to make all decisions, take all actions as may be
necessary for the Partnership to perform fully, and promptly satisfy and
discharge each and every obligation or responsibility of the Partnership. The
General Partner may take all necessary and appropriate action to consummate a

        4.2 SPECIFIC POWERS OF THE GENERAL PARTNER. By way of illustration of
the General Partner's power and authority pursuant to Section 4.1 and not as a
limitation thereon, the General Partner shall have the unilateral right and
power to take any and all of the following actions on behalf of the Partnership
except to the extent any such action requires Approval by Partnership Vote
pursuant to Section 4.3 of this Agreement:

            (a) to consummate the transaction contemplated in the Purchase
Agreement and the Mortgage Loan and to execute all documents necessary or
advisable in connection therewith; provided, however, that no material change in

as may be lawfully carried on or performed by a limited partnership under the
laws of each state in which the Partnership is then formed, qualified, or does
business.

        4.3  MAJOR DECISIONS. All "Major Decisions" (hereinafter defined) with
respect to the Partnership business shall require Approval by Partnership Vote.
All Major Decisions shall be made by the Partners in a timely manner with due
regard for the necessity of obtaining and evaluating the information necessary
for making such Major Decisions. A "MAJOR DECISION" as used in this Agreement

           (a) any merger or consolidation of the Partnership with another

total cost of the Property and secure a first lien mortgage to pay off the
interim debt, which first lien mortgage shall not be at a rate in excess of 200
basis points over the corresponding treasury rate, (ii) refinance the Property
at a lower interest rate, and (iii) refinance the Property, if as a result of

collect unpaid rent and eviction suits;

contained herein to the contrary, until the second (2nd) anniversary of the date
of this Agreement, the Partnership shall not sell the Property or refinance the
Mortgage Loan without the approval of Realty America (which approval shall not
be unreasonably withheld). The foregoing limitation shall not apply to the
Mortgage Loan, it being specifically agreed that the General Partner shall have
the authority to execute on behalf

                                       13
<PAGE>

of the Partnership any and all documents the General Partner deems necessary or
advisable in order to consummate the Mortgage Loan.

Operating Budgets which shall be prepared in accordance with the Property
Management Subcontract; provided, that if the Property Management Subcontract is
not in effect then the Operating Budgets shall be prepared by the General
Partner and subject to Approval by Partnership Vote. After an annual Operating
Budget has been approved, the General Partner shall implement it on behalf of
the Partnership (including in accordance with the Property Management
Subcontract) and may cause the Partnership to incur the expenditures and
obligations therein provided. The General Partner shall submit (or request the
manager of the Property to submit) to the Limited Partners any proposed
Operating Budget for each calendar year by November 15 of the preceding calendar
year. Provided that each of the Limited Partners receives the proposed Operating
Budget for each calendar year by November 15 of the preceding calendar year,
together with all supporting information necessary for the Limited Partners to
review the Operating Budget, each Limited Partner will approve, reject, or
provide changes to the Operating Budget by December 15 of the year in which the
proposed Operating Budget was submitted to the Limited Partners. If an Operating
Budget for any calendar year has not been approved by January 1 of that year,
the Partnership shall continue to operate under the Operating Budget for the
previous year with such adjustments as may be necessary to reflect deletion of
non-recurring expense items set forth on the previous Operating Budget and
increased insurance costs, taxes, utility costs, and debt service payments.

        4.6 LIMITED PARTNER PARTICIPATION IN MANAGEMENT. The Limited Partners,
as limited partners, shall not participate in the operation or management of the
business of the Partnership, or transact any business for or in the name of the
Partnership, and the Limited Partners, as the limited partners, shall not have
any right or power to sign for or bind the Partnership in any manner, except as
expressly provided under the provisions of this Agreement. Any rights of the
Limited Partners to consent to and approve of certain matters under the
provisions of this Agreement shall not be deemed a participation in the
operation and management of the business of the Partnership or the exercise of
control of the Partnership business. Except as may be otherwise expressly
provided herein, the Limited Partners shall not have the right to vote on any
matter concerning the management and affairs of the Partnership.

        4.7 PAYMENT OF COSTS AND EXPENSES. The Partnership will be responsible
for paying all costs and expenses of forming and continuing the Partnership,
acquiring the Property, and conducting the business of the Partnership,
including, without limitation, accounting costs, legal expenses and office
supplies. In the event any such costs and expenses are incurred and paid by the
General Partner on behalf of the Partnership, then, except as expressly provided
to the contrary in this Agreement, such Partner shall be entitled to be
reimbursed for such payment so long as such cost or expense was reasonably
necessary and is reasonable in amount. The Partnership may use the proceeds of
any revenues of the Partnership to reimburse a Partner for any such costs and
expenses so paid.

        4.8 TRANSACTIONS WITH AFFILIATES. Any agreement whereby any service or
activity to be performed for the Partnership is to be performed by an Affiliate
of a Partner shall require Approval by a Partnership Vote. The Partners hereby
acknowledge and agree that Approval by Partnership Vote has been obtained with
respect to the Management Agreement, the Property Management Subcontract, and
the Leasing Agreement.

        4.9 FEES PAYABLE BY THE PARTNERSHIP.

            (a) Upon the acquisition of the Property, the Partnership shall pay
to Realty America or its Affiliate designee a brokerage commission in the amount

<PAGE>

            (b) The Partnership shall contract with HPT for HPT to perform
management services in respect of the Property in accordance with the Management
Agreement, pursuant to which HPT will receive a management fee from the
Partnership as set forth in the Management Agreement.

            (c) The Partners acknowledge and agree that HPT will subcontract
with the Trammell Crow Provider to perform management services in respect of the
Property in accordance with the Management Agreement, as set forth in the
Property Management Subcontract.

            (d) The Partnership shall enter into the Leasing Agreement with the
Trammell Crow Provider (and the General Partner is hereby authorized to execute
the Leasing Agreement on behalf of the Partnership).

            (e) Realty America shall be entitled to act as the exclusive listing
agent in connection with any sale of the Property. Accordingly, Realty America
shall perform such services as are customarily performed by listing agents for
property similar to the Property in the Dallas/Fort Worth area, and such
services shall be substantial services in connection with the sales effort
performed on behalf of the Partnership as agent for the General Partner (or
Affiliate designated by the General Partner) in respect of the disposition of
the Property. In consideration of such efforts, the Partnership shall pay to
Realty America a market rate sales commission, payable if and when the closing
of the sale of the Property occurs. Notwithstanding the preceding sentence: (i)
in no event shall the total sales commission payable by the Partnership pursuant
to the preceding sentence exceed two percent (2%) of the gross sales proceeds
received by the Partnership for the Property; and (ii) if any broker other than
Realty America is involved in the sale of the Property, Realty America shall be
obligated to pay any commission due to such broker.

        4.10 OTHER COMPENSATION. Except as provided in this Agreement, no
Partner or its Affiliate shall be entitled to any compensation unless Approval
by Partnership Vote is obtained with respect thereto.

                                   ARTICLE V.

their Capital Contributions to the Partnership, and the Limited Partners shall
not be required to contribute any capital to the Partnership for any obligations
to third parties in excess of the Capital Contributions actually made under
Sections 3.1 and 3.2 hereof.

            (b) LIMITATION ON LIABILITY OF GENERAL PARTNER. The General Partner
(including its members, officers, directors, agents, employees and
representatives) shall not be liable or responsible in damages or otherwise to

                                       15
<PAGE>

sustained by it or any of them in connection with the Partnership, provided that
the General Partner has determined in good faith that such course of conduct was
in, and not opposed to, the best interests of the Partnership and such liability
or loss was not the result of gross negligence or willful misconduct, or a
material breach of this Agreement on the part of the General Partner or such
person, and (2) any such indemnification will only be recoverable from the
assets of the Partnership and the Limited Partners shall not have any liability
on account thereof. All rights to indemnification permitted herein and payment

administrative or criminal action, suit or proceeding against any person who may
be entitled to indemnification pursuant to this Section 5.2 may be paid by the
Partnership in advance of the final disposition of such action, suit or
proceeding, if (i) the legal action relates to the performance of duties or
services by such person on behalf of the Partnership, (ii) the legal action is
initiated by a third party who is not a Limited Partner, and (iii) such person
undertakes to repay the advanced funds to the Partnership in cases in which it
is not entitled to indemnification under this Section 5.2.

            (c) The term "General Partner" as used in this Section 5.2 shall
include any additional or substitute general partner and any Affiliate of a
General Partner performing services on behalf of the Partnership.

        5.3 OTHER BUSINESS ACTIVITIES. Subject to the other express provisions
of this Agreement, each Partner and any Affiliate thereof may engage in and
possess interests in other business ventures of any and every type and

                                  ARTICLE VII.

                        ALLOCATION OF PROFITS AND LOSSES

        7.1 ALLOCATION OF PROFITS AND LOSSES. After application of Section 7.3
hereof, Profits and Losses for each fiscal year shall be allocated among the
Partners so as to reduce, proportionately, in the case of any Profits, the
difference between their respective Target Accounts and Partially Adjusted
Capital Accounts for such fiscal year and, in the case of Losses, the difference
between their respective Partially Adjusted Capital Accounts and Target Accounts
for such fiscal year. To the extent that, in the fiscal year in which all or
substantially all of the Partnership's assets are disposed of, or in the fiscal
year in which the Partnership is liquidated, the allocation of Profit or Loss
set forth in the preceding sentence does not cause each Partner's Partially
Adjusted Capital Account balance to equal the balance of its Target Account,
items of income or gain will be reallocated to any Partner with a Partially
Adjusted Capital Account which is less than its Target Account, and items of
loss, deduction or expense will be reallocated to any Partner with a Partially
Adjusted Capital Account that is greater than its Target Account in such manner
as to reduce, to the greatest extent possible, the difference between each
Partner's respective balance in its Target Account and its Partially Adjusted
Capital Account balance.

        7.2 LIMITATION ON LOSS ALLOCATIONS. Notwithstanding anything in this
Agreement to the contrary, no Losses or item of deduction shall be allocated to
a Partner if such allocation would cause the Capital Account of such Partner to
have a deficit in excess of the sum of (a) the amount of additional capital such
Partner would be required to contribute to the Partnership if the Partnership
were to dissolve on the last day of the accounting period to which such
allocation relates plus (b) such Partner's distributive share of Partnership
Minimum Gain as of the last day of such accounting period, determined pursuant
to Regulations Section 1.704-2(g)(1), plus (c) such Partner's share of Partner
Minimum Gain as of the last day of such year, determined pursuant to Regulation
Section 1.704-2(i)(5). Any amounts not allocated to a Partner pursuant to the
limitations set forth in this paragraph shall be allocated to the other Partners
to the extent possible without violating the limitations set forth in this
paragraph. For purposes of the foregoing provisions, the balance of a Partner's
Capital Account shall be determined after reducing such Capital Account by (i)
all anticipated allocations of loss or deduction pursuant to Sections 704(e)(2)
and 706(d) of the Code, and Section 1.751-1(b)(2)(ii) of the Regulations, and
(ii) anticipated distributions to such Partner to the extent such anticipated
distributions exceed anticipated increases to such Partner's Capital Account
during or prior to the year of distribution (other than increases which may not
be taken into account pursuant to Section 1.704-1(b)(2)(ii)(d)(6) of the
Regulations).

        7.3 SPECIAL ALLOCATIONS. The following special allocations shall be made
in the following order:

            (a) MINIMUM GAIN CHARGEBACK. Except as otherwise provided in Section
1.704-2(f) of the Regulations, in the event there is a net decrease in
Partnership Minimum Gain during a Partnership taxable year, each Partner shall
be allocated (before any other allocation is made pursuant to this Section 7.3)
items of income and gain for such year (and, if necessary, for subsequent years)
equal to that Partner's share of the net decrease in Partnership Minimum Gain.
The determination of a Partner's share of the net decrease in Partnership
Minimum Gain shall be determined in accordance

                                       17
<PAGE>

with Regulations Section 1.704-2(g). The items to be specially allocated to the
Partners in accordance with this Section 7.3(a) shall be determined in
accordance with Regulation Section 1.704-2(f)(6). This Section 7.3(a) is
intended to comply with the Minimum Gain chargeback requirement set forth in
Section 1.704-2(f) of the Regulations and shall be interpreted consistently
therewith.

            (b) PARTNER MINIMUM GAIN CHARGEBACK. Except as otherwise provided in
Section 1.704-2(i)(4), in the event there is a net decrease in Partner Minimum
Gain during a Partnership taxable year, each Partner who has a share of that
Partner Minimum Gain as of the beginning of the year, to the extent required by
Regulation Section 1.704-2(i)(4), shall be specially allocated items of
Partnership income and gain for such year (and, if necessary, subsequent years)
equal to that Partner's share of the net decrease in Partner Minimum Gain.
Allocations pursuant to this subparagraph (b) shall be made in accordance with
Regulation Section 1.704-2(i)(4). This Section 7.3(b) is intended to comply with
the requirement set forth in Regulation Section 1.704-2(i)(4) and shall be
interpreted consistently therewith.

            (c) QUALIFIED INCOME OFFSET ALLOCATION. In the event any Partner
unexpectedly receives any adjustments, allocations or distributions described in
Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or
1.704-1(b)(2)(ii)(d)(6) or which would cause the negative balance in such
Partner's Capital Account to exceed the sum of (i) his obligation to restore a
Capital Account deficit upon liquidation of the Partnership, plus (ii) his share
of Partnership Minimum Gain determined pursuant to Regulation Section
1.704-2(g)(1), plus (iii) such Partner's share of Partner Minimum Gain
determined pursuant to Regulation Section 1.704-2(i)(5), items of Partnership
income and gain shall be specially allocated to such Partner in an amount and
manner sufficient to eliminate such excess negative balance in his Capital
Account as quickly as possible. This Section 7.3(c) is intended to comply with
the alternative test for economic effect set forth in Regulation Section
1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

            (d) GROSS INCOME ALLOCATION. In the event any Partner has a deficit
Capital Account at the end of any Partnership fiscal year which is in excess of
the sum of (i) any amounts such Partner is obligated to restore pursuant to this
Agreement, plus (ii) such Partner's distributive share of Minimum Gain as of
such date, plus such Partner's share of Partner Minimum Gain determined pursuant
to Regulation Section 1.704-2(i)(5), each such Partner shall be specially
allocated items of Partnership income and gain in the amount of such excess as
quickly as possible, provided that an allocation pursuant to this Section 7.3(d)
shall be made only if and to the extent that such Partner would have a deficit
Capital Account in excess of such sum after all other allocations provided for
in this Section 7.3 have been made, except assuming that Section 7.3(c) above
and this Section 7.3(d) were not contained in this Agreement.

            (e) ALLOCATION OF NONRECOURSE DEDUCTIONS. Nonrecourse Deductions
shall be allocated to the Partners in accordance with their respective Residual
Percentages.

            (f) ALLOCATION OF PARTNER NONRECOURSE DEDUCTIONS. Partner
Nonrecourse Deductions shall be allocated as prescribed by the Regulations.

            (g) BASIS ADJUSTMENT UNDER SECTION 754. To the extent an adjustment
to the adjusted tax basis of any Partnership assets pursuant to Code Section
734(b) or Code Section 743(b) is required, pursuant to Regulations Section
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain, if the adjustment increases the basis of the asset, or loss, if
the adjustment decreases such basis, and such gain or loss shall be specially
allocated to the Partners in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such Section of the
Regulations.

                                       18
<PAGE>

        7.4 BUILT-IN GAIN OR LOSS/SECTION 704(C) TAX ALLOCATIONS. In the event
that the Capital Accounts of the Partners are credited with or adjusted to
reflect the Gross Asset Value of the Partnership's property and assets, the
Partners' distributive shares of depreciation, depletion, amortization, and gain
or loss, as computed for tax purposes, with respect to such property, shall be
determined pursuant to Section 704(c) of the Code and the Regulations
thereunder, so as to take account of the variation between the adjusted tax
basis and Gross Asset Value of such property in a manner determined by Approval
by Partnership Vote. Any deductions, income, gain or loss specially allocated
pursuant to this Section 7.4 shall not be taken into account for purposes of
determining Profits or Losses or for purposes of adjusting a Partner's Capital
Account.

        7.5 RECAPTURE. Ordinary income arising from the recapture of
depreciation and unrecaptured Section 1250 gain shall be allocated to the
Partners in the manner that is prescribed by the Regulations, or if the
Regulations do not prescribe a manner in which depreciation is to be recaptured,
then depreciation shall be recaptured in the same manner as such depreciation
was allocated to the Partners.

        7.6 RETENTION OF SECTION 751 ASSETS. Upon the occurrence of an event
which would otherwise cause a reduction in a Partner's respective interest in
the Partnership's Section 751 assets ("substantially appreciated inventory" and
"unrealized receivables" as defined in Section 751 of the Code), such as the
admission of new Partners or otherwise, no such reduction shall occur with
respect to Partners who were Partners immediately preceding such event and who
continue to be Partners after the occurrence of such event but, rather, each
such Partner shall retain his respective interest in the Partnership's Section
751 assets existing immediately prior to such event.

        7.7 PROHIBITION AGAINST RETROACTIVE ALLOCATIONS. Notwithstanding
anything in this Agreement to the contrary, no Partner shall be allocated any
loss, credit or income attributable to a period prior to his admission to the
Partnership. In the event that a Partner Transfers all or a portion of his
Partnership interest, or if there is a reduction in a Partner's Residual
Percentage due to the admission of new Partners or otherwise, each Partner's
distributive share of Partnership items of income, loss, credit, etc., shall be
determined by taking into account each Partner's varying interests in the
Partnership during the Partnership's taxable year. For this purpose, each
Partner's distributive share shall be estimated by taking the pro rata portion
of the distributive share such Partner would have included in his taxable income
had he maintained his Residual Percentage throughout the Partnership year. Such
proration shall be based upon the portion of the year during which such Partner
held the Residual Percentage, except that extraordinary, nonrecurring items
shall be allocated to the persons holding Partnership interests at the time such
extraordinary items occur.

        7.8 ALLOCATION OF NONRECOURSE LIABILITIES. The "excess nonrecourse
liabilities" of the Partnership (within the meaning of Section 1.752-3(a)(3) of
the Regulations) shall be allocated to the Partners in accordance with their
respective Residual Percentages.

ARTICLE VIII.

                        TRANSFER OF PARTNERSHIP INTEREST

        8.1 PROHIBITION ON DISPOSITION OF GENERAL PARTNER'S INTEREST. Unless
Approval by Partnership Vote is otherwise obtained, or except as otherwise
permitted in this Agreement, the General Partner may not, directly or
indirectly, by operation of law or otherwise (a) withdraw or resign from the
Partnership, or (b) Transfer any or all of its interest in the Partnership. In
addition, the General Partner shall not permit the Transfer of any interest in
the General Partner unless Approval by Partnership Vote is

                                       19
<PAGE>

obtained with respect to such Transfer. Any act in violation of this Section 8.1
shall be null and void as against the Partnership and the Limited Partners,
except as otherwise required by law.

        8.2 GENERAL PARTNER CEASING TO BE A GENERAL PARTNER. Unless Approval by
Partnership Vote is otherwise obtained, a General Partner shall cease to be a
General Partner of the Partnership upon the happening of any of the following
events (hereinafter each referred to as an "EVENT OF WITHDRAWAL"):

            (a) such General Partner makes an assignment for the benefit of
creditors; files a voluntary petition of bankruptcy; is adjudicated as bankrupt
or insolvent or is the subject of an order for relief under the bankruptcy laws;
files a petition or answer seeking for itself any reorganization, arrangement or
similar relief under any statute, law or regulation; files an answer or other
pleading admitting or failing to contest the material allegations of a petition
filed against it in any proceeding of this nature; or seeks, consents to or
acquiesces in the appointment of a trustee, receiver or liquidator of all or any
substantial part of its properties;

            (b) such General Partner fails to dismiss within one hundred twenty
(120) days after the commencement of any proceeding which attempts to attach or
charge the General Partner's Partnership interest or which seeks reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief against the General Partner under any statute, law or regulation, or if
within ninety (90) days after a court order attaching or charging its
Partnership interest or the appointment without its consent or acquiescence of a
trustee, receiver or liquidator of such General Partner or all or any
substantial part of its properties, the order or appointment is not vacated or
stayed, or within ninety (90) days after the expiration of any such stay, the
order or appointment is not vacated;

            (c) In the case of any General Partner which is a corporation,
limited partnership or limited liability company, the filing of a certificate of
dissolution or its equivalent for the corporation, limited partnership or
limited liability company, or the revocation of its charter or authority to do
business in the jurisdiction of its formation;

            (d) The withdrawal of a General Partner from the Partnership as
provided in Section 8.1 above; or

            (e) The Transfer by a General Partner of all or any part of its
interest in the Partnership except as approved by Partnership Vote pursuant to
Section 8.1.

            Any person ceasing to be a General Partner (other than as a result
of paragraph (d) and (e) of this Section 8.2) shall automatically become a
limited partner of the Partnership having the same percentage interest in the
profits, losses and distributions of the Partnership that it had while it was a
general partner, and provided further that in the event that the Partners elect
to continue the Partnership pursuant to Section 12.1(b) below, and a new General
Partner is admitted to the Partnership to enable the Partnership to continue,
then the General Partner being converted to a limited partner shall Transfer a
..005% Residual Percentage to the newly admitted general partner. Such Transfer
shall not reduce the interest in the Partnership of any Partner other than the
General Partner which is being converted to a limited partner.

        8.3 GENERAL PROHIBITION AGAINST TRANSFERS OF LIMITED PARTNER'S INTEREST.
A Limited Partner may not Transfer any or all of such Partner's interest in the
Partnership except as permitted in Section 8.4. Any act in violation of this
Article shall be null and void as against the Partnership and the Partners,

<PAGE>

        8.4 CONDITIONS UPON TRANSFERS BY A LIMITED PARTNER. A Limited Partner
may Transfer all or any part of such Partner's interest in the Partnership only
with the written consent of the General Partner and Approval by Partnership
Vote; provided, however, that the General Partner's written consent shall not be
given unless:

                (i) the General Partner is satisfied that the proposed Transfer
will not have any adverse effect upon the Partnership or the Partners under
federal income tax laws then in effect or cause any default in any loan
documents of the Partnership or the Property owner;

                (ii) the General Partner has received, if requested, an opinion
from counsel for the Partnership to the effect that such Transfer will not
violate federal or state securities laws or regulations; and

                (iii) the person, firm or entity to acquire such interest agrees
to comply with all terms of this Agreement, including without limitation Section
8.5 below.

        8.5 SUBSTITUTION OF ASSIGNEE. No Transferee of the whole or any portion
of a Limited Partner's interest in the Partnership shall have the right to be
admitted to the Partnership and become a Limited Partner unless and until all of
the Partners in their absolute discretion consent and all of the following
conditions are satisfied:

            (a) the Transferor and Transferee execute and acknowledge a written
instrument of assignment, together with such other instruments as the General
Partner may deem necessary or desirable to effect the admission of the
Transferee as a substitute Limited Partner; and

            (b) an instrument specifically Transferring such interest, signed by
both assignor and assignee, shall be filed with the General Partner, and until
such instrument is so filed, the Partnership shall not recognize any Transfer of
interest for the purposes of making payments of profits, income or any other
distribution with respect to such interest.

        8.6 BUY-SELL IN EVENT OF OFFER TO PURCHASE ASSETS.

            (a) If a BONA FIDE offer is made to the Partnership for the purchase
of the then-remaining portion of the Property still owned by the Partnership,
the General Partner shall notify the Partners of such offer, and if one or more
Partners desires to accept such offer and the other Partners do not, then the
Partners who do not want to accept the offer (whether one or more, the
"PURCHASING PARTNER") shall, at the request of the Partners who want to accept
the offer (whether one or more, the "SELLING PARTNER"), purchase the interest in
the Partnership owned by the Selling Partner. The purchase price payable by the
Purchasing Partner to the Selling Partner shall be an amount equal to the amount
which the Selling Partner would have received had the Property been sold by the
Partnership for the amount offered which the Selling Partner wished to accept.
Closing shall occur at the offices of the Partnership no later than 60 days
following the date notice from the Selling Partner is delivered to the
Purchasing Partner, requesting that the Purchasing Partner purchase the Selling
Partner's Partnership Interest.

            (b) At the closing, the applicable interests in the Partnership
shall be duly conveyed, free of all liens and encumbrances. The purchase price
shall be paid by wire transfer of immediately available federal funds, unless a
different manner of payment was set forth in the offer or is otherwise agreed to
by the Partnership. At the election of the Purchasing Partner, the applicable
interests in the Partnership to be purchased may be acquired in the name of a
nominee (whether or not such nominee is an Affiliate of the Purchasing Partner),
provided, that the Purchasing Partner shall have designated such

                                       21
<PAGE>

nominee by written notice prior to the date of purchase. It shall be a condition
of the Selling Partner's obligation to proceed with any such purchase that the
Purchasing Partner shall have obtained releases of any guaranties of
indebtedness of the Partnership executed by the Selling Partner or any
Affiliates of (or principals in) the Selling Partner. The Purchasing Partner, in
addition to paying at the closing the purchase price, shall be obligated to loan
to the Partnership an amount sufficient to discharge at the closing all
outstanding and unpaid obligations of the Partnership to the Selling Partner as
of such time.

            (c) Upon receipt of the purchase price, the Selling Partner shall
execute and deliver all documents reasonably required to transfer the interest
in the Partnership being sold. The Selling Partner shall also execute such
resignations and other documents as may be reasonably required by counsel for
the Partnership to accomplish the withdrawal of the Selling Partner as a Partner
of the Partnership and the Purchasing Partner shall assume all of the Selling
Partner's obligations to the Partnership and any of its creditors under any
loans to the Partnership permitted by this Agreement, such assumptions to be in
form reasonably satisfactory to counsel for the Selling Partner.

            (d) It is expressly agreed that the remedy at law for breach of any
of the obligations set forth in this Section 8.6 is inadequate in view of (i)
the complexities and uncertainties in measuring the actual damages that would be
sustained by reason of the failure of a Partner to comply fully with each of
said obligations, and (ii) the uniqueness of the Partnership business and
Partners' relationship. Accordingly, each of the aforesaid obligations shall be,
and is hereby expressly made, enforceable by specific performance.

        8.7 AUTHORITY OF GENERAL PARTNER. For purposes of Section 8.6 above, the
General Partner and BH Fund shall be treated as one Partner and the General
Partner shall make all decisions on behalf of the General Partner and BH Fund in
respect of the procedure set forth in Section 8.6. BH Fund hereby irrevocably
constitutes and appoints the General Partner as its attorney-in-fact with full
power to bind BH Fund hereunder and execute documents of transfer on its behalf.

        8.8 COST AND EXPENSE OF TRANSFER; ALLOCATION OF PROFITS AND LOSSES. All
costs and expenses incurred by the Partnership in connection with any
disposition of a Partner's interest, including any filing, recording and
publishing costs and the fees and disbursements of counsel, shall be paid by the
Partner disposing of such interest. If an interest in the Partnership is
disposed of pursuant to this Article VIII, the selling Partner shall
nevertheless be entitled to a portion of the profits and be charged with a
portion of the losses allocated to such interest or part thereof for the fiscal
year of the Partnership in which such disposition occurs, consistent with
Section 7.7 above.

                                  ARTICLE IX.

                        OWNERSHIP OF PARTNERSHIP PROPERTY

        All real or personal property, including all improvements placed or
located thereon, acquired by the Partnership shall be owned by and in the name
of the Partnership, such ownership being subject to the other terms and
provisions of this Agreement.

<PAGE>

            (a) Proper books and records shall be kept with reference to all
Partnership transactions at the principal place of business of the Partnership,
and each Partner shall at all reasonable times during business hours have access
thereto. The books shall be kept in such manner of accounting as shall properly
reflect the actions of the Partnership in accordance with accounting principles
generally accepted within the industry and consistently applied on such basis as
will, in the opinion of the Partnership's accountants, be most advantageous to
the Partnership. The books and records shall include the designation and
identification of any property in which the Partnership owns a beneficial
interest. The books and records of the Partnership shall be reviewed annually at
the expense of the Partnership by an independent certified public accountant
selected by the General Partner, who shall prepare and deliver to the
Partnership, for filing, the appropriate federal Partnership income tax
return(s) before March 31 of each year. The General Partner shall provide each
Limited Partner with a copy of the Partnership income tax return at least ten
(10) business days prior to filing such return. The Partnership shall report its
operations for tax purposes on the accrual basis.

            (b) The General Partner shall, at Partnership expense, furnish (or
request the manager of the Property to furnish) to the Partners (i) on or before
the twentieth (20th) day of each calendar quarter, an unaudited statement
setting forth and describing in reasonable detail the receipts and expenditures
of the Partnership during the preceding calendar quarter and comparing the
results of operations of the Partnership for such calendar quarter and for the
year to date to the appropriate Operating Budget, (ii) on or before one hundred
twenty (120) days after the end of each fiscal year, a balance sheet of the
Partnership dated as of the end of such fiscal year, a statement of the

as determined by Approval by Partnership Vote, and (iii) from time to time, all
other information relating to the Partnership and the business and its affairs
reasonably requested by any Partner.

        10.3 ACCOUNTS. All funds of the Partnership shall be deposited in its
name in an account or accounts maintained at a bank designated by the General
Partner or with an agent designated by the General Partner. Checks shall be
drawn upon the Partnership account or accounts only for purposes of the
Partnership and shall be signed by the General Partner.

        10.4 FEDERAL TAX ELECTIONS. All elections for federal tax purposes,
including but not limited to an election to adjust the basis of the assets of
the Partnership pursuant to Section 754 of the Code, and the adoption of
accelerated depreciation or cost recovery methods required or permitted to be
made by the Partnership under the Code shall be determined by Approval by
Partnership Vote.

        10.5 TAX AUDITS. The General Partner shall be designated as the "tax
matters partner" of the Partnership as defined in Sections 6221 ET SEQ, of the
Code and, in the event of an audit of the Partnership by the Internal Revenue
Service ("IRS"), the General Partner, at Partnership expense, shall have the
exclusive right to conduct all negotiations with the Internal Revenue Service on
behalf of the Partnership, and the attorneys and accountants selected by the
Partners to conduct such negotiations are hereby specifically authorized by the
Partners to act on behalf of the Partnership in such negotiations, and each
Partner will execute such further authority as the IRS may require to permit the
General Partner and its selected attorneys and accountants to so represent the
Partners; provided the General Partner shall not take any action take any action
contemplated by Sections 6222 through 6232 of the Code without prior Approval by
Partnership Vote. This provision is not intended to authorize the General
Partner to take any action left to the determination of an individual Partner
under Sections 6222 through 6232 of the Code.

                                    AMENDMENT

        11.1 AUTHORITY TO AMEND. Except as provided in Section 11.2 below, this

this Agreement, notwithstanding the occurrence of any event which would
otherwise result in a dissolution of the Partnership pursuant to the law of the
State of Texas, and no Partner shall be released or relieved of any duty or
obligation hereunder by reason of any such dissolution; provided, however, that

            (b) Upon the occurrence of any Event of Withdrawal of a General
Partner at a time when there is no other General Partner, the Partnership shall
be continued if, within a period of ninety (90) days from the date of such
occurrence, all other Partners agree in writing that the Partnership shall be
continued and designate one or more individuals or legal entities to be admitted
to the Partnership as a General Partner, which agreement shall be effective as
of the date of the occurrence of the applicable Event of Withdrawal. Any such
individual or legal entity shall, upon admission to the Partnership, succeed to
all of the rights and powers of a General Partner hereunder.

            (c) Dissolution of the Partnership shall be effective on
December 31, 2053 or the day on which the event occurs giving rise to the
dissolution, but the Partnership shall not terminate until the Certificate shall
have been canceled and the assets of the Partnership shall have been distributed
as provided below. Notwithstanding the dissolution of the Partnership, prior to
the termination of the Partnership as aforesaid, the business of the Partnership
and the affairs of the Partners shall continue to be governed by this Agreement.

            (d) The bankruptcy, insolvency, dissolution, or adjudication of
incompetency of a Limited Partner shall not cause the dissolution of the
Partnership. In the event of the bankruptcy, or incompetency of a Limited
Partner, its administrators or representatives ("Successor") shall have the same
rights that such Limited Partner would have had if it had not become bankrupt,
except that, in the event of bankruptcy, such Successor shall have no right to
participate in the management of the Partnership or vote on any Partnership
matter unless such Successor is admitted to the Partnership as a Limited Partner
pursuant to Section 8.5, and the interest of such Limited Partner in the
Partnership shall, until the termination of the Partnership, otherwise be
subject to the terms, provisions and conditions of this Agreement as if such
Limited Partner had not become bankrupt. In the event of any other withdrawal of
a Limited Partner, the Limited Partner shall only be entitled to Partnership
distributions distributable to it but not actually paid to it prior to such
withdrawal and shall not have any right to have its interest in the Partnership
purchased or paid for.

            (e) Notwithstanding anything in this Agreement to the contrary,
upon a sale of all or substantially all of the assets of the Partnership in a
single transaction (a "SINGLE SALE TRANSACTION") where all or any portion of the
consideration payable to the Partnership is to be received by the Partnership
more than ninety (90) days after the date on which such Single Sale Transaction
occurs, the Partnership shall continue for purposes of collecting the deferred
payments and making distributions to the Partners. In such event (i) gain
recognized and cash distributed in any year as a result of such Single Sale
Transaction shall be allocated and distributed among the Partners in the same
proportion as such gain and cash would have been allocated and distributed were
the entire gain resulting from such Single Sale Transaction required to be
recognized for Federal income tax purposes in the year in which such Single Sale
Transaction occurred; and (ii) income attributable to interest on deferred
payments shall be allocated among, and such interest shall be distributed to,
the Partners as if the deferred payment obligations received by the Partnership
had been distributed to the Partners pursuant to Section 6.1.

        12.2 WIND-UP OF AFFAIRS. As expeditiously as possible following the
occurrence of an event giving rise to a termination of the Partnership pursuant
to Section 12.1 above, the General Partner(s) or, if none, all of the Limited
Partners or a liquidator appointed by all of the Limited Partners (the General
Partner, Limited Partners or such liquidator, as the case may be, is referred to
here as the "LIQUIDATOR") shall liquidate the assets of the Partnership, apply
and distribute the proceeds thereof as contemplated by

                                       25
<PAGE>

this Agreement and cause the cancellation of the Certificate. As soon as
possible after the dissolution of the Partnership, a full account of the assets
and liabilities of the Partnership shall be taken, and a statement shall be
prepared by the independent accountants then acting for the Partnership setting
forth the assets and liabilities of the Partnership. A copy of such statement
shall be furnished to each of the Partners within ninety (90) days after such
dissolution. Thereafter, the Liquidator shall wind up the affairs of the
Partnership and distribute the Partnership assets in the following order of
priority:

            (a) to creditors (including Partners who are creditors) in
satisfaction of the liabilities of the Partnership, other than liabilities to
existing and former Partners for distributions from the Partnership;

            (b) to the establishment of any reserves which the Liquidator deems
reasonably necessary for any contingencies or unforeseen liabilities or
obligations of the Partnership. Such reserves shall be paid over by the
Liquidator to an escrow agent or shall be held by the Liquidator for the purpose
of disbursing such reserves in payment of any of such contingencies. At the
expiration of such period as the Liquidator deems advisable, the balance thereof
shall be distributed in the manner and order provided in this Section;

            (c) to existing and former Partners in satisfaction of any
liabilities to them, if any, for distributions from the Partnership;

            (d) to Partners in accordance with Section 6.1 above.

         Notwithstanding anything to the contrary, in the event the Partnership
is "liquidated" within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g)
and an event described in Section 12.1(a) shall have occurred, liquidating
distributions shall be made pursuant to this Section 12.2 by the end of the
taxable year in which the Partnership is liquidated, or, if later, within ninety
(90) days after the date of such liquidation. Distributions pursuant to the
preceding sentence may be made to a trust for the purpose of an orderly
liquidation of the Partnership by the trust in accordance with the Act.

        12.3 COMPLIANCE WITH TREASURY REGULATIONS. It is the intent of the
Partners that the allocations provided in Section 7.1 result in distributions
required pursuant to Section 12.2(d) being in accordance with positive Capital
Accounts as provided for in the Treasury Regulations under Code Section 704(b).
However, if after giving hypothetical effect to the allocations required by
Section 7.1, the Capital Accounts of the Partners are in such ratios or balances
that distributions pursuant to Section 12.2(d) would not be in accordance with
the positive Capital Accounts of the Partners as required by the Treasury
Regulations under Code Section 704(b), such failure shall not affect or alter
the distributions required by Section 12.2(d). Rather, the liquidator will have
the authority to make other allocations of Profits and Losses (or items thereof)
among the Partners which, to the extent possible, will result in the Capital
Accounts of each Partners having a balance prior to distribution equal to the
amount of distributions to be received by such Partners pursuant to Section
12.2(d).

        12.4 NO DEFICIT CAPITAL ACCOUNT OBLIGATION. Notwithstanding anything
else to the contrary in this Agreement, upon a liquidation within the meaning of
Section 1.704-1(b)(2)(ii)(g) of the Regulations, if any Partner has a deficit
Capital Account (after giving effect to all contributions, distributions,
allocations and other Capital Account adjustments for all taxable years,
including the year during which such liquidation occurs), such Partner shall
have no obligation to make any Capital Contribution, and the negative balance of
such Partner's Capital Account shall not be considered a debt owed by such
Partner to the Partnership or to any other Person for any purpose whatsoever.

                                       26
<PAGE>

        12.5 DISTRIBUTION IN KIND. If any assets of the Partnership are to be
distributed in kind, the net fair market value of such assets as of the date of
dissolution shall be determined by independent appraisal or by agreement of the
Partners. Prior to distribution, such assets shall be deemed to have been sold
for their fair market values and the Capital Accounts of the Partners shall be
adjusted pursuant to the terms of this Agreement to reflect the allocation of
gain or loss which would have resulted from such deemed sale.

        12.6 CANCELLATION OF CERTIFICATE. Upon the dissolution and the final
liquidation of the Partnership, there shall be filed for record as provided by
Texas law a Certificate of Cancellation executed by the General Partner.

        12.7 RETURN OF CONTRIBUTION NONRECOURSE TO OTHER PARTNERS. Except as
provided by law or as expressly provided in this Agreement, upon dissolution
each Partner shall look solely to the assets of the Partnership for the return
of its Capital Contribution. If the Partnership property remaining after the
payment or discharge of the debts and liabilities of the Partnership is
insufficient to return the cash contribution of one or more Partners, such
Partner or Partners shall have no recourse against any other Partner.

                                 ARTICLE XIII.

PROVISIONS PURSUANT TO SECTION 5.2.

                                  ARTICLE XIV.

                          SECURITIES LAW CONSIDERATIONS

        14.1 NO REGISTRATION/RESTRICTION ON SALE. THE PARTNERSHIP INTERESTS HAVE
NOT BEEN REGISTERED WITH THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION
UNDER THE SECURITIES ACT OF 1933, NOR HAVE THEY BEEN REGISTERED WITH THE
SECURITIES COMMISSION OF ANY OTHER APPLICABLE STATE, INCLUDING WITHOUT
LIMITATION THE STATE OF TEXAS. THE PARTNERSHIP INTERESTS MAY BE ACQUIRED FOR
INVESTMENT PURPOSES ONLY AND MAY NOT BE OFFERED FOR SALE, PLEDGED, HYPOTHECATED,
SOLD OR TRANSFERRED EXCEPT IN COMPLIANCE WITH THE TERMS AND CONDITIONS OF THIS
AGREEMENT AND IN A TRANSACTION WHICH IS EITHER EXEMPT FROM REGISTRATION UNDER
SUCH ACTS OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACTS.

        14.2 COMPLIANCE WITH SECURITIES LAWS. The Limited Partners acknowledge
and confirm that their Limited Partnership interests have not been registered
under any federal or state securities laws by virtue of exemptions from the
registration provisions thereof and consequently cannot be sold except pursuant
to appropriate registration or exemption from registration as applicable. No
Transfer of all or any part of a Limited Partnership interest (except a Transfer
upon the death, incapacity or bankruptcy of a Limited Partner to his personal
representative and beneficiaries), including, without limitation, any Transfer
of a right to distributions, profits and/or losses to a person who does not
become a Partner, may be made unless the Partnership is provided with an opinion
of counsel acceptable to the General Partner (both as to the identity of the
counsel and the substance of the opinion) to the effect that such offer or
assignment (a) may be effected without registration under the Securities Act of
1933, as amended, or the Investment Company Act of 1940, as amended, and (b)
does not violate any applicable federal or state securities laws (including any
investment suitability standards) applicable to the Partnership or the General
Partner.

        14.3 ACCESS TO INFORMATION. Each of the Limited Partners represents to
the General Partner and the Partnership that before determining to enter into
this Agreement and to invest in the Partnership, each Limited Partner made an
independent investigation into the Partnership and the General Partner and that
it received whatever information it deemed necessary or relevant in order to
decide whether to enter into this Agreement or invest in the Partnership. Each
Limited Partner acknowledges that the financial materials provided to the
Limited Partners are only estimates of expected future operations based on
assumptions about future markets and there is no assurance that such projections
will be realized.
