                                TITLE AND SURVEY

        2.1     COMMITMENT FOR TITLE INSURANCE. Within five (5) days after the
Effective Date, Seller shall deliver to Purchaser and the surveyor described in
Section 2.2 below (a) a current title commitment (the "TITLE COMMITMENT")
covering the Property, showing all matters affecting title to the Property and

Insurance in the full amount of the Purchase Price pursuant to Section 2.5

shall, at Seller's expense, furnish to Purchaser a current Survey (the "SURVEY")
of the Property prepared by a reputable surveyor or surveying firm licensed by

        2.3     TITLE REVIEW PERIOD. After receipt of the last of the Title
Commitment, legible copies of the Exception Instruments, and the Survey,
Purchaser shall have a period of ten (10) days to review the state of Seller's
title to the Property (the "TITLE REVIEW PERIOD"). If the Survey, the Title
Commitment or the Exception Instruments reflect or disclose any defect,
exception or other matter affecting the Property ("TITLE DEFECTS") that is
unacceptable to Purchaser for any reason whatsoever, then prior to the
expiration of the Title Review Period, Purchaser may provide Seller with written
notice of its objections, and Seller shall have ten (10) days (the "CURE
PERIOD") from the date of the notice to remove or cure any Title Defects to the
satisfaction of Purchaser. Seller shall use its reasonable, good faith efforts
to remove or cure the Title Defects to Purchaser's satisfaction, but shall not
be required to incur any costs in doing so (other than as provided in Section
2.4 below) or to institute litigation. If Seller does not cure any or all of the
Title Defects within the Cure Period, Seller shall notify Purchaser in writing,
prior to the expiration of the Cure Period, of its failure to cure such Title
Defects, and Purchaser may, prior to the later of (a) five (5) days after
receipt of Seller's notice of its failure to cure, or (b) the expiration of the
Inspection Period (hereinafter defined) either (i) terminate this Agreement by
written notice delivered to Seller, or (ii) elect to waive any uncured Title
Defect. If Purchaser fails to terminate the Agreement by written notice
delivered to Seller prior to the expiration of the time period referenced in the
immediately preceding sentence, then any Title Defects that Seller has not cured
shall be deemed waived by Purchaser. If Purchaser shall fail to notify Seller in
writing of any objections to the state of Seller's title to the Property as
shown by the Title Commitment, the Exception Documents or the Survey, or if
Purchaser elects to waive all or any of the Title Defects, or is deemed to have
waived all or any of the Title Defects, then any exceptions to Seller's title to
which Purchaser has not objected or which have been objected to and waived by
Purchaser and which are disclosed by the Title Commitment shall be considered to
be Permitted Exceptions. If Purchaser terminates this Agreement pursuant to this
section, then neither Seller nor Purchaser shall have any further rights or
obligations under this Agreement and the Earnest Money shall be returned to
Purchaser.

        2.4     OBLIGATION TO CURE LIENS. Notwithstanding anything to the
contrary contained in this Article II, if at Closing there are any mechanic's or
materialmen's liens or mortgages, deeds of trust or other instruments creating a
lien for borrowed money against all or any part of the Property (collectively,
"LIENS"), Seller shall discharge the same of record or, if Seller disputes the
validity of any such lien, Seller shall post a cash bond pending final
determination thereof (such that such lien does not appear as an exception in
the Title Policy, as hereinafter defined) and apply such portions of the
Purchase Price or Seller's funds as may be necessary to accomplish the same.

        2.5     OWNER'S POLICY OF TITLE INSURANCE. At Closing, Seller shall
cause the Title Company to issue to Purchaser, at Seller's expense, an Owner's
Policy of Title Insurance (the "TITLE POLICY") covering the Property, in the
full amount of the Purchase Price, in the form prescribed by the Texas State
Board of Insurance, insuring that Purchaser is the owner of good and
indefeasible fee simple title to the Property, subject only to the Permitted
Encumbrances, and with the standard printed exceptions modified as follows: (a)
the exception for area and boundaries shall be limited to "shortages in area";
(b) the exception for ad valorem taxes shall reflect only taxes for the current
year and subsequent years, and subsequent assessments for prior years due to
changes in land usage or ownership, and shall be endorsed "not yet due

                                       3
<PAGE>

and payable"; (c) there shall be no exception for "visible and apparent
easements," for "public or private roads" or the like; (d) there shall be no
exception for "rights of parties in possession," although there may be an
exception for Leases specifically described in the Title Policy; and (e) any
reference to submitting claims under the Title Policy to arbitration shall be
deleted. Purchaser shall pay the survey deletion premium (if it so elects), the
incremental cost of a Lender's Title Policy (if necessary) and any costs
associated with Purchaser's loan (if any).

                                  ARTICLE III

                                INSPECTION PERIOD

        3.1     RIGHT OF INSPECTION. During the period (hereinafter referred to
as the "INSPECTION PERIOD") beginning upon the Effective Date and ending at 5
p.m., Dallas, Texas time, on June 24, 2004, Purchaser shall have the right to
make a physical inspection of the Property, to conduct tests thereon (including
specifically, without limitation, environmental tests and soil borings), to
review the Due Diligence Materials (as hereinafter defined) and all other books,
records and documents maintained by Seller relating to the Property, and to make
inquiries to governmental authorities and other appropriate parties, so as to
determine, at the sole discretion of Purchaser, whether the Property is suitable
for Purchaser's purposes. Purchaser agrees to indemnify and hold Seller harmless
of and from any claim for physical damages or physical injuries arising from
Purchaser's inspection of the Property, and notwithstanding anything to the
contrary in this Agreement, such obligation to indemnify shall survive Closing
or any termination of this Agreement. All inspections shall occur at reasonable
times and shall be conducted so as not to unreasonably interfere with use of the
Property by Seller or its tenants.

        PURCHASER ACKNOWLEDGES THAT SELLER HAS NOT MADE AND DOES NOT MAKE AND IS
UNWILLING TO MAKE ANY EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES AS TO THE
PRESENT, PAST OR FUTURE PHYSICAL CONDITION, INCOME, EXPENSES, OPERATION,
LEGALITY OF OCCUPANCY OR ANY OTHER MATTER AFFECTING OR RELATED TO THE PROJECT
EXCEPT AS SPECIFICALLY SET FORTH IN THIS AGREEMENT. No representation, warranty
or covenant made by Seller in this Agreement or any document delivered pursuant
hereto shall survive the Closing except as expressly provided in this Agreement.
PURCHASER AGREES TO PURCHASE THE PROJECT IN ITS "AS IS" CONDITION (BUT SUBJECT
TO THE EXPRESS REPRESENTATIONS AND WARRANTIES HEREIN).

        3.2     RIGHT OF TERMINATION. Seller agrees that in the event Purchaser
determines, in Purchaser's sole discretion, that the Property is not suitable
for its purposes, or that it is in the interest of Purchaser to terminate this
Agreement for any other reason, then Purchaser shall have the right to terminate
this Agreement by sending written notice thereof (hereinafter referred to as the
"NOTICE OF TERMINATION") to Seller prior to the expiration of the Inspection
Period. Upon delivery by Purchaser of such Notice of Termination within the
Inspection Period, this Agreement shall terminate and the Earnest Money shall be
returned to Purchaser. If Purchaser fails to send Seller a Notice of Termination
prior to the expiration of the Inspection Period, Purchaser shall no longer have
any right to terminate this Agreement under this Article III.

<PAGE>

                (a)     pay to Seller the amount of the Purchase Price in cash

                (c)     deliver to Seller such evidence as Seller's counsel

        4.4     CREDITS AND PRORATIONS. The following provisions shall govern
the apportionment of income and expenses with respect to the Property between
Seller and Purchaser:

                (a)     Real estate taxes and assessments and personal property
taxes shall be prorated between Seller and Purchaser at Closing. If the Closing
shall occur before the amount of taxes is fixed, the apportionment of taxes
shall be made based upon the tax rate for the preceding year, applied to the
latest assessed valuation of the Property. Upon receipt of the actual tax bill
for the Property, the proration of taxes made at Closing shall be subject to
adjustment pursuant to Section 4.4(i) below.

                (b)     Expenses under the Operating Agreements shall be

utilities used through the day preceding the Closing Date and Purchaser shall be
responsible for the payment of utilities used on or after the Closing Date. With
respect to any utility for which there is no meter or for which a meter reading
cannot be or is not obtained on the day preceding the Closing Date, the expenses
for such utility shall be prorated between Seller and Purchaser at Closing based
upon the most current bill for such utility. Any deposits for utilities shall
inure to the benefit of and be deemed assigned to Purchaser. Seller and
Purchaser shall cooperate to cause the transfer of utility company accounts from
Seller to Purchaser.

                (d)     Basic rents ("BASIC RENT") and additional rent relating
to escalation and pass-throughs of operating and other similar expenses
("ADDITIONAL RENT") shall be prorated between Seller and Purchaser based upon
Basic Rent and Additional Rent actually collected. All prepaid Basic Rent,
Additional Rent and other income from the Property shall be credited to
Purchaser at Closing, to the extent same is attributable to a period of time
after Closing. With respect to Additional Rent which is paid based upon an
estimate, with an end-of-year accounting and adjustment, after Closing Seller
and Purchaser shall make any adjustments to the proration of such items made at
Closing at such time as the final tax and operating expenses numbers become
available and such end-of-year accountings are completed. Any Additional Rent
which may be due Seller as a result of such re-prorations shall be paid by
Purchaser to Seller if and when such Additional Rent is collected by Purchaser.

                (e)     Basic Rent and Additional Rent which is delinquent and
remains uncollected at Closing shall not be prorated between Seller and
Purchaser at Closing. At Closing, Seller shall furnish to Purchaser a schedule
of delinquent Basic Rent and Additional Rent due under the Leases. Purchaser
shall pay Seller's prorata share of any delinquent Basic Rent and Additional
Rent if and when collected by Purchaser; provided, however, that Purchaser shall
use reasonable efforts (without having any obligation to terminate any lease or
institute litigation) to collect or pursue the collection of same. It is
understood and agreed that any Basic Rent or Additional Rent collected by
Purchaser after Closing shall be applied

                                       6
<PAGE>

first to currently due Basic Rent and Additional Rent. Purchaser shall hold all
landlord's liens in the entireties thereof to enforce the payment of rentals to
which Purchaser is entitled, and Seller shall be deemed to have transferred to
Purchaser all of such landlord's liens.

                (f)     All security deposits and other deposits payable to
tenants under the Leases shall be credited to Purchaser at Closing.

                (g)     Purchaser shall receive a credit at Closing of
$80,000.00 for the amount required to replace the roof on the Improvements.

                (h)     Purchaser shall receive a credit at Closing for the
amount of (i) $56,229.12 representing the free rent under the Medical Edge
Healthcare Group, Inc. lease from the Closing Date until October 1, 2004 (such
amount to be reduced by $585.72 per day should the Closing Date be extended) ;
and (ii) the unused tenant improvement allowance due to the tenant Medical Edge
Healthcare Group, Inc. of $120,491.00 less any amounts delivered to said tenant
or paid on tenants behalf by Seller prior to the Closing Date.

                (i)     The prorations described in this Section 4.4 shall be
made as of 12:01 a.m. on the Closing Date, as if Purchaser were vested with
title to the Property during the entire day upon which Closing occurs. All
prorations described in this Section 4.4 shall be effected by increasing or
decreasing, as the case may be, the amount of cash to be paid by Purchaser to
Seller at Closing. Seller and Purchaser agree to adjust between themselves after
Closing any errors or omissions in the prorations made at Closing; provided,
however, that such prorations shall be deemed final and not subject to further
post Closing adjustments if no such adjustments have been requested within one
(1) year after the Closing Date.

        4.5     CLOSING COSTS. Seller shall pay (a) the fees of any counsel
representing it in connection with this transaction; (b) the cost of the Title
Policy; (c) the cost of the Survey; (d) the fees for recording the deed
conveying the Property to Purchaser; and (e) one-half (1/2) of any escrow fee

one-half (1/2) of any escrow fees charged by the Title Company. All other costs
and expenses incident to this transaction and the closing thereof shall be paid
by the party incurring same.

        WAIVER OF CONSUMER RIGHTS: Purchaser represent and warrants to Seller
that Purchaser has knowledge and experience in real estate, financial and
business matters, such as the transaction contemplated by this Contract, that
enable Purchaser to evaluate the merits and risks of the transaction
contemplated by this Agreement. Further, Purchaser acknowledges that Purchaser
is not in a significantly disparate bargaining position relative to Seller with
respect to this Agreement. TO THE EXTENT APPLICABLE AND PERMITTED BY LAW (AND
WITHOUT ADMITTING SUCH APPLICABILITY), PURCHASER HEREBY WAIVES THE PROVISIONS OF
THE TEXAS DECEPTIVE TRADE PRACTICES-CONSUMER PROTECTION ACT, CHAPTER 17,
SUBCHAPTER E, SECTIONS 17.41 THROUGH 17.63, INCLUSIVE (A LAW THAT GIVES
CONSUMERS SPECIAL RIGHTS AND PROTECTIONS) AFTER CONSULTATION WITH AN ATTORNEY OF
ITS OWN SELECTION, PURCHASER VOLUNTARILY CONSENTS TO THIS WAIVER.

        5.2     COVENANTS OF SELLER. Seller hereby covenants with Purchaser as
follows:

                (a)     Seller will endeavor to deliver to or make available for
inspection to Purchaser such documents and other items (the "DUE DILIGENCE
MATERIALS") as Purchaser may reasonably request to the extent that such items
are within Seller's possession.

                (b)     So long as this Agreement remains in effect, Purchaser
will be allowed access to the Property and the books and records related to the
Property under the terms and conditions set forth in Section 3.1 hereof.

                (c)     So long as this Agreement remains in effect, Seller
shall not negotiate, execute or commit to enter into (i) any Lease; or (ii) any
modification, amendment, restatement or renewal of any Lease, without
Purchaser's prior written consent in each instance.

                (d)     So long as this Agreement remains in effect, Seller
shall not enter into any other contract (or an extension or modification of any
other contract) with respect to the Property which will survive the Closing or
otherwise affect the use, operation or enjoyment of the Property after the
Closing, without first obtaining Purchaser's prior written consent thereof.

                (e)     After the date hereof and prior to Closing, no part of
the Property, or any interest therein, will be alienated, liened, encumbered or
otherwise transferred.

                (f)     Pending Closing, Seller shall operate and manage the
Property in a normal businesslike manner, maintaining present services and
insurance policies, and shall maintain the Property in good repair and working
order, shall keep on hand sufficient materials, supplies, equipment, inventory
and other personal property for the efficient operation and management of the
Property, and shall perform when due, all of Seller's obligations under the
Leases and other contracts affecting the Property and otherwise in accordance
with applicable laws, ordinances, rules and regulations affecting the Property.
Seller shall deliver the Property at Closing in substantially the same condition
as it was on the Effective Date, reasonable wear and tear excepted. None of the
Personal Property shall be removed from the Property, unless replaced by
personal property of equal or greater utility and value.

                (g)     Seller has paid or will pay in full, prior to Closing,
all bills and invoices for labor, goods, materials and services of any kind with
respect to the Property and utility charges relating to the period prior to
Closing. Without limiting the foregoing, any and all leasing commissions and
Tenant Inducement Costs due and payable on or before the Closing Date with
respect to Leases in existence on the Effective Date or Leases obtained prior to
Closing will be paid in full by Seller on or before the Closing Date. As used
herein, the term "Tenant Inducement Costs" means any payment required under a

                                       9
<PAGE>

Lease to be paid by the landlord thereunder to or for the benefit of the tenant
thereunder which is in the nature of a tenant inducement, including specifically
without limitation, tenant improvement costs, lease buyouts and moving
allowances.

                (h)     Seller shall promptly notify Purchaser of any change in
any condition with respect to the Property or of any event or circumstance which
makes any representation or warranty of Seller to Purchaser under this Agreement
untrue or misleading, or any covenant of Seller under this Agreement incapable
or less likely of being performed, it being understood that Seller's obligation
to provide notice to Purchaser under this Section 5.2 shall in no way relieve
Seller of any liability for a breach by Seller of any of its representations,
warranties or covenants in this Agreement.

        5.3     REPRESENTATIONS AND WARRANTY OF PURCHASER. Purchaser hereby
represents and warrants to Seller:

                (a)     Purchaser has the full right, power and authority to
enter into this Agreement and to carry out Purchaser's obligations hereunder,
and to perform all of its obligations under this Agreement, and the execution
and delivery of this Agreement and the performance by Purchaser of its
obligations under this Agreement requires no further action or approval of
Purchaser's partners or of any other person in order to constitute this
Agreement as a binding and enforceable obligation of Purchaser.

        5.4     SURVIVAL OF OBLIGATIONS. Seller and Purchaser agree as follows:

                (a)     The representations and warranties made by Seller herein
shall be continuing and shall be deemed to be made by Seller as of the Closing
Date with the same force and effect as if made at and as of that time. All
representations, warranties and covenants made by Seller herein shall survive
Closing for a period of one (1) year, unless a longer survival period is
expressly provided herein. Seller shall indemnify and hold Purchaser free and
harmless from and against all losses, costs, damages and expenses of every kind
and nature whatsoever (including reasonable attorneys' fees and costs) sustained
by Purchaser as a result of any breach of any representation, warranty or
covenant made by Seller in this Agreement.

                (b)     The representations and warranties made by Purchaser
herein shall be continuing and shall be deemed to be made by Purchaser as of the
Closing Date with the same force and effect as if made at and as of that time.
All representations and warranties of Purchaser shall survive Closing for a
period of two (2) years. Purchaser shall indemnify and hold Seller free and
harmless from and against all losses, costs, damages, and expenses of every kind
and nature whatsoever (including reasonable attorneys' fees and costs) sustained
by Seller as a result of any breach of any representation or warranty made by
Purchaser.

        5.5     AUDIT BY PURCHASER. Purchaser has advised Seller that Purchaser
must cause to be prepared up to three (3) years of audited financial statements
in respect of the Property in compliance with the policies of Purchaser and
certain laws and regulations, including, without limitation, Securities and
Exchange Commission Regulation S-X, Rule 3-14. Seller agrees to use reasonable
efforts to cooperate with Purchaser's auditors in the preparation of such
audited financial statements (it being understood and agreed that the foregoing
covenant shall survive Closing). Without limiting the generality of the
preceding sentence (a) Seller shall, during normal business hours, allow
Purchaser's auditors reasonable access to the books and records maintained by
Seller in respect of the Property; (b) Seller shall use reasonable efforts to
provide to Purchaser such financial information and supporting documentation as
are necessary for Purchaser's auditors to prepare audited financial statements;
and (c) if Seller has audited financial statements with respect to the Property,
Seller shall promptly provide Purchaser's auditors with a copy of such audited
financial statements. If after Closing Seller obtains an audited

                                       10
<PAGE>

financial statement in respect of the Property for a fiscal period in 2004 that
was not completed at the time of Closing, then Seller shall promptly provide
Purchaser with a copy of such audited financial statement, and the foregoing
covenant shall survive Closing. Seller has advised Purchaser that Seller
Purchased the Property in December of 2002 and cannot vouch for the accuracy of
any records prior to such purchase. All of Seller's records are un-audited.

                                   ARTICLE VI

                       Conditions Precedent To The Closing

        6.1     CONDITIONS PRECEDENT OF PURCHASER. In addition to all other
conditions set forth in this Agreement, Purchaser's obligation to consummate the
Closing is subject to the satisfaction of each and every one of the conditions
precedent set forth in this section 6.1 (all of which are for the sole benefit
of Purchaser):

                (a)     prior to or on the Closing Date, Purchaser shall have
received an Estoppel Certificate in the form of EXHIBIT I attached hereto and
made a part hereof executed by each tenant under the Leases of the Property;

                (b)     As of the Closing Date, no tenant of the Property shall
be the subject of any bankruptcy or other insolvency proceeding.

                (c)     All representations of Seller set forth in Section 5.1
shall be true, correct and complete in all material respects as of the Effective
Date and shall be true, correct and complete in all material respects as of the
Closing Date.

                (d)     Seller shall have performed in all material respects all
obligations required to be performed by Seller hereunder prior to or in
connection with the Closing.

        6.2     CONDITIONS PRECEDENT OF SELLER. In addition to all other
conditions set forth in this Agreement, Seller's obligation to consummate the
Closing is subject to the satisfaction of each and every one of the conditions
precedent set forth in this Section 6.2 (all of which are for the sole benefit
of Seller):

                (a)     All representations of Purchaser set forth in Section
5.3 shall be true, correct and complete in all material respects as of the
Effective Date and shall be true, correct and complete in all material respects

                (b)     Purchaser shall have performed in all material respects
all obligations required to be performed by Purchaser hereunder prior to or in
connection with the Closing.

        6.3     FAILURE OF CONDITION PRECEDENT. Upon the failure of any of the
foregoing conditions precedent, the party benefitted by such failed condition
shall have the option to (a) waive such condition precedent and proceed to
Closing, or (b) terminate this Agreement by sending written notice to the party,
on or before the date of Closing, in which event the Earnest Money shall be
returned to Purchaser.

<PAGE>

                                  ARTICLE VII

                                     DEFAULT

        7.1     DEFAULT BY PURCHASER. In the event that Purchaser fails to
consummate this Agreement for any reason, except Seller's default or the
permitted termination of this Agreement by either Seller or Purchaser as herein
expressly provided, Seller shall be entitled, as its sole and exclusive remedy,
to terminate this Agreement and receive the Earnest Money as liquidated damages
for the breach of this Agreement, it being agreed between the parties hereto
that the actual damages to Seller in the event of such breach are impractical to
ascertain and the amount of the Earnest Money is a reasonable estimate thereof.
In the event that Purchaser closes under this Agreement and then fails to fully
and timely perform any of its other obligations under this Agreement that
survive or are performable after the Closing, Seller may seek all remedies
available at law or in equity.

        7.2     DEFAULT BY SELLER. In the event that Seller fails to consummate
this Agreement for any reason, except Purchaser's default or the permitted
termination of this Agreement by Seller or Purchaser as herein expressly
provided, Purchaser shall be entitled, as its exclusive remedies, either (i) to
terminate this Agreement by giving written notice thereof to Seller, whereupon
neither party shall have any further rights or obligations under this Agreement
and the Earnest Money shall be returned to Purchaser, or (ii) to enforce
specific performance of Seller's obligations under this Agreement; provided,
however, if Seller's default is such that specific performance cannot be granted
as a judicial remedy, then Purchaser may seek any and all other remedies
available at law or in equity. In the event Purchaser closes under this
Agreement and then Seller fails to fully perform any of its other obligations
under this Agreement that survive or are performable after the Closing,
Purchaser may seek all remedies available at law or in equity.

                                  ARTICLE VIII

                                  RISK OF LOSS

        8.1     MINOR DAMAGE. In the event of loss or damage to the Property or
any portion thereof (the "premises in question") which is not "major" (as
hereinafter defined), this Agreement shall remain in full force and effect
provided Seller performs any necessary repairs or, at Seller's option, reduces
the cash portion of the Purchase Price in an amount equal to the cost of such
repairs, Seller thereby retaining all of Seller's right, title and interest to
any claims and proceeds Seller may have with respect to any casualty insurance
policies or condemnation awards relating to the premises in question. In the
event that Seller elects to perform repairs upon the Property, Seller shall use
reasonable efforts to complete such repairs promptly and the date of Closing
shall be extended a reasonable time (but in no event more than thirty (30) days)
in order to allow for the completion of such repairs.

        8.2     MAJOR DAMAGE. In the event of a "major" loss or damage,
Purchaser may terminate this Agreement by written notice to Seller, in which
event the Earnest Money shall be returned to Purchaser. If Purchaser does not
send written notice to Seller that Purchaser has elected to proceed with Closing
within ten (10) days after Seller sends Purchaser written notice of the
occurrence of major loss or damage, then Purchaser shall be deemed to have
elected to terminate this Agreement and the Earnest Money shall be returned to
Purchaser. If Purchaser sends notice to Seller within such ten (10) day period
that Purchaser desires to proceed with Closing, this Agreement shall remain in
effect, provided that the Purchase Price shall be reduced by an amount equal to
the cost of repairing the Property to its condition prior to the occurrence of
the major loss or damage. Upon Closing, full risk of loss with respect to the
Property shall pass to Purchaser. For purposes of Sections 8.1 and 8.2, "major"
loss or damage refers to the following: (i) loss or damage to the Property or
any portion thereof such that the cost of repairing or

                                       12
<PAGE>

restoring the premises in question to a condition substantially identical to
that of the premises in question prior to the event of damage would be, in the
certified opinion of a mutually acceptable architect, equal to or greater than
One Hundred Thousand and No/100 Dollars ($100,000.00), and (ii) any loss due to
a condemnation.

                                   ARTICLE IX

                                   COMMISSIONS

        9.1     BROKERAGE COMMISSIONS. Each party agrees that should any claim
be made for brokerage commissions or finder's fees by any broker or finder by,
through or on account of any acts of said party or its representatives, said
party will hold the other party free and harmless from and against any and all
loss, liability, cost, damage and expense in connection therewith. The
provisions of this paragraph shall survive Closing.

                                   ARTICLE X

                                  MISCELLANEOUS

        10.1    DISCLAIMERS. IT IS EXPRESSLY UNDERSTOOD AND AGREED THAT
PURCHASER IS PURCHASING THE PROPERTY "AS IS" AND "WHERE IS," AND WITH ALL FAULTS
AND THAT SELLER IS MAKING NO REPRESENTATIONS OR WARRANTIES WITH RESPECT TO THE
PROPERTY, EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT.

        10.2    ASSIGNMENT. Purchaser shall have the right to assign its rights
under this Agreement without the consent of Seller.

        10.3    TITLE POLICY OR ABSTRACT. The Texas Real Estate License Act
requires written notice to Purchaser that it should have an attorney examine an
abstract of title to the property being purchased or obtain a title insurance
policy. Notice to that effect is, therefore, hereby given to Purchaser.

        10.4    NOTICES. Any notice pursuant to this Agreement shall be given in
writing by (a) personal delivery, or (b) expedited delivery service with proof
of delivery, or (c) United States Mail, postage prepaid, registered or certified
mail, return receipt requested, or (d) prepaid telegram, telex or telecopy
(provided that such telegram, telex or telecopy is confirmed by expedited
delivery service or by mail in the manner previously described), sent to the
intended addressee at the address set forth below, or to such other address or
to the attention of such other person as the addressee shall have designated by
written notice sent in accordance herewith, and shall be deemed to have been
given either at the time of personal delivery, or, in the case of expedited
delivery service or mail, as of the date of first attempted delivery at the
address and in the manner provided herein, or, in the case of telegram, telex or
telecopy upon receipt. Unless changed in accordance with the preceding sentence,

computing any period of time described in this Agreement, the day of the act or
event after which the designated period of time begins to run is not to be
