     4.   Purchaser's Inspection and Review Rights. Subject to the rights of the
          ----------------------------------------
Tenant, Purchaser and its agents, engineers, or representatives, with Seller's
reasonable, good faith cooperation, shall have the privilege of going upon the
Property as needed to inspect, examine, test, and survey the Property at all
reasonable times and upon reasonable prior notice and from time to time.
Purchaser hereby agrees to indemnify, defend and hold Seller harmless from any
liens, claims, liabilities, and damages incurred through the exercise of such
privilege, and Purchaser further agrees to repair any damage to the Property
caused by the exercise of such privilege.  All such inspections shall be non-
destructive in nature and specifically shall not include any physically
intrusive testing; provided however, that if Purchaser desires to undertake such
intrusive testing, Purchaser shall first obtain Seller's written approval which
shall not be unreasonably withheld if Purchaser conducts such testing in
accordance with commercially customary standards; and provided further that if
Purchaser's Phase I Environmental Report recommends a Phase II investigation,
Seller shall be entitled to withhold its consent to such investigation in its
sole discretion.  At all reasonable times prior to the Closing (as hereinafter
defined), Seller shall make available to Purchaser, or Purchaser's agents and
representatives, for review and copying, all books, records, and files in
Seller's possession relating to the operation of the Property, including,
without limitation, title matters, surveys, tenant files, service and
maintenance agreements, and other contracts, books, records, operating
statements, and other information relating to the Property; provided, however,
Seller shall not be required to deliver or make available to Purchaser any
appraisals, budgets, strategic plans, internal analyses, information regarding
the marketing of the Property for sale, attorney and accountant work product or
privileged documents and/or other information which would not be relevant in
connection with a customary due diligence investigation of a property comparable
to the Property.  Seller further agrees to provide to Purchaser prior to the
date which is five (5) days after the effective date of this Agreement, to the
extent the same are in the possession of or under the control of Seller, the
most current boundary and "as-built" surveys of the Land and Improvements and
any title insurance policies, building inspection reports, environmental
reports, certificates of occupancy, building permits, ad valorem tax bills,
certificates of insurance and instruments reflecting the approval of any
association governing the Property relating thereto. Seller further agrees to
assist in good faith and cooperate with Purchaser in the review of the books,
records, and files relating to the Property. At no cost to Seller, Seller shall
request the authors of  existing  environmental reports to issue reliance
letters addressed to Purchaser and Purchaser's lender, if any, and provide
Purchaser with an introduction so Purchaser might pursue the matter.  If the
Closing is not consummated hereunder, Purchaser shall promptly deliver copies of
all reports, surveys and other information furnished to Purchaser by third
parties in connection with Purchaser's inspections of the Property; provided
however, that the delivery of such copies and information shall be without
warranty or representation whatsoever, express or implied.  Purchaser shall
maintain and shall insure that Purchaser and Purchaser's consultants and
contractors maintain public liability insurance and property damage insurance in
an amount not less than Two Million Dollars ($2,000,000) and in form and
substance adequate to insure against all liability of Purchaser and its
consultants and contractors, respectively, and each of their respective agents,
employees and contractors, arising out of inspections and testing of the
Property or any part thereof made on Purchaser's behalf and, at Seller's
request, Purchaser shall furnish Sellers with appropriate certificates and
endorsements reflecting Seller as an additional insured under any such
insurance.

     5.   Special Condition to Closing. Purchaser shall have to and through
          ----------------------------
August 27, 2001 (the "Inspection Period") to make investigations, examinations,
inspections, market studies, feasibility studies, lease reviews, and tests
relating to the Property and the operation thereof in order to determine, in
Purchaser's sole opinion and discretion, the suitability of the Property for
acquisition by Purchaser. Purchaser shall have the right to terminate this
Agreement at any time prior to the expiration of the Inspection Period by giving
written notice to Seller of such election to terminate. In the event Purchaser
so elects to terminate this Agreement, Seller shall be entitled to receive and
retain the sum of Twenty-Five Dollars ($25.00) of the Earnest Money, and the
balance of the Earnest Money

                                       2
<PAGE>

shall be promptly refunded by Escrow Agent to Purchaser, whereupon, except as
expressly provided to the contrary in this Agreement, no party hereto shall have
any other or further rights or obligations under this Agreement. Seller
acknowledges that the sum of $25.00 is good and adequate consideration for the
termination rights granted to Purchaser hereunder.

     6.   General Conditions Precedent to Purchaser's Obligations Regarding the
          ---------------------------------------------------------------------
Closing. In addition to the conditions to Purchaser's obligations set forth in
-------
Paragraph 5 above, the obligations and liabilities of Purchaser hereunder shall
in all respects be conditioned upon the satisfaction of each of the following
conditions, any of which may be waived by written notice from Purchaser to
Seller:

          (a) Seller shall have complied in all material respects with and
     otherwise performed in all material respects each of the covenants and
     obligations of Seller set forth in this Agreement, as of the date of
     Closing (as hereinafter defined).

          (b) All representations and warranties of Seller as set forth in this
     Agreement shall be true and correct in all material respects as of the date
     of Closing.

          (c) The Title Company shall be prepared to issue to Purchaser upon the
     Closing a fee simple owner's title insurance policy on the Land and
     Improvements without exceptions other than as described in paragraph 7
     pursuant to the Title Commitment.

          (d) Purchaser shall have received the Tenant Estoppel Certificate

     hereinafter defined) at least five (5) business days prior to Closing.

          (e) Tenant shall be in possession of its premises under the Lease, and
     rent shall have Commenced under the Lease.

     7.   Title and Survey.  Seller covenants and agrees that Seller shall, on
          ----------------
or before ten (10) days after the Effective Date of this Agreement, cause
Chicago Title Insurance Company, or such other such title insurance company
acceptable to Purchaser (herein referred to as the "Title Company"), to deliver
to Purchaser its commitment (herein referred to as the "Title Commitment") to
issue to Purchaser, upon the recording of the Deed conveying title to the
Property from Seller to Purchaser, the payment of the Purchase Price, and the
payment to the Title Company of the policy premium therefor, an owner's policy
of title insurance, in the amount of the Purchase Price, insuring good and
marketable fee simple record title to the Property to be in Purchaser subject
only to the Permitted Exceptions (as hereinafter defined), with affirmative
coverage over any mechanic's, materialman's and subcontractor's liens. Such
Title Commitment shall not contain any exception for rights of parties in
possession other than an exception for the right of the Tenant under the Lease.
If the Title Commitment shall contain an exception for the state of facts which
would be disclosed by a survey of the Property or an "area and boundaries"
exception, the Title Commitment shall provide that such exception will be
deleted upon the presentation of the Texas equivalent of an ALTA/ASCM survey
acceptable to Title Company, in which case the Title Commitment shall be amended
to contain an exception only for the matters shown on the as-built survey which
Purchaser shall obtain at its sole cost and expense. Seller shall also cause to
be delivered to Purchaser together with such Title Commitment, legible copies of
all documents and instruments referred to therein. Purchaser, upon receipt of
the Title Commitment and the copies of the documents and instruments referred to
therein, shall then have twenty (20) days during which to examine the same,
after which Purchaser shall notify Seller in writing (the "Objection Notice") of
any defects or objections affecting the marketability of the title to the
Property. In the event the Objection Notice is not timely delivered to Seller,
then except for matters arising subsequent to the effective date of the Title
Commitment and Monetary Liens, Purchaser shall be deemed to have waived all
other title objections and such matters which are not objected to in the
Objection Notice shall be deemed a "Permitted Exception." Within five (5) days
after Seller's receipt of the Objection Notice, Seller shall deliver to
Purchaser a written notice (the "Response Notice") indicating whether Seller
elects to cure the objections identified in the Objection Notice, except that in
all events Seller shall be required to cure the following: outstanding deeds of
trust and other security interests arising by, through or under Seller,
undisputed mechanics and materialmen's liens, delinquent ad valorem property
taxes and assessments and judgment liens ("Monetary Liens"). Failure to timely
deliver a Response Notice shall be deemed to be an election by Seller not to
cure any matters described in the Objection Notice. In the event Seller elects
in the Response Notice not to cure any of Purchaser's objections in the
Objection Notice, Purchaser may elect to terminate this Agreement and receive
the Earnest Money by delivery within three (3) days after Purchaser's

                                       3
<PAGE>

receipt of the Response Notice or Seller's deemed election, of a written notice
of termination (the "Election Notice"). In the event Purchaser fails to timely
elect to terminate this Agreement through the delivery of an Election Notice,
Purchaser shall be deemed to elect not to terminate this Agreement pursuant to
this Paragraph 7, and Seller shall convey title subject to the matters set forth
in the Objection Notice which Seller has not agreed to cure, provided that in
all events, Seller shall cure Monetary Liens.

representations and warranties of Seller in this Agreement remain true and
correct as of the date of the Closing, except for any changes in any such
representations or warranties that occur and are disclosed by Seller to
Purchaser expressly and in writing at any time and from time to time prior to
Closing upon their occurrence, which disclosures shall thereafter be updated by

<PAGE>

the Lease is terminable or rent thereunder may be reduced or abated, Seller
shall give Purchaser immediate written notice of such threatened or contemplated
condemnation or of such taking or sale, and Purchaser may by written notice to
Seller given within fifteen (15) days of the receipt of such notice from Seller,
elect to cancel this Agreement. If Purchaser chooses to cancel this Agreement in
accordance with this Paragraph 17, then the Earnest Money shall be returned
immediately to Purchaser by Escrow Agent and the rights, duties, obligations,
and liabilities of the parties hereunder shall immediately terminate and be of
no further force and effect. If Purchaser does not elect to cancel this
Agreement in accordance herewith, this Agreement shall remain in full force and
effect and the sale of the Property contemplated by this Agreement, less any
interest taken by eminent domain or condemnation, or sale in lieu thereof, shall
be effected with no further adjustment and without reduction of the Purchase
Price, and at the Closing, Seller shall assign, transfer, and set over to
Purchaser all of the right, title, and interest of Seller in and to any awards

          ---------------------
or damaged prior to the Closing, and the estimated cost of repair or replacement
exceeds $250,000.00 or if the Lease shall terminate as a result of such damage,
Purchaser may, by written notice given to Seller within fifteen (15) days after
receipt of written notice from Seller of such damage or destruction, elect to
terminate this Agreement, in which event the Earnest Money shall immediately be
returned by Escrow Agent to Purchaser and except as expressly provided herein to
the contrary, the rights, duties, obligations, and liabilities of all parties
hereunder shall immediately terminate and be of no further force or effect. If
Purchaser does not elect to terminate this Agreement pursuant to this Paragraph
18, or has no right to terminate this Agreement (because the damage or
destruction does not exceed $250,000.00 and the Lease remains in full force and
effect), and the sale of the Property is consummated, Purchaser shall be
entitled to receive all insurance proceeds paid or payable to Seller by reason
of such destruction or damage under the insurance required to be maintained by
Seller pursuant to Paragraph 9(d) hereof (less amounts of insurance theretofore
received and applied by Seller to restoration). If the amount of said casualty
or rent loss insurance proceeds is not settled by the date of Closing, Seller

similar instruments to ensure that Purchaser shall receive all of Seller's
right, title, and interest in and under said insurance proceeds.

broker or agent to claim a real estate commission with respect to the conveyance

Heritage Title Company of Austin, Inc., as Escrow Agent, hereby acknowledges
receipt of Purchaser's wire transfer in the amount of $250,000.00, tendered as
Earnest Money to be held by Escrow Agent in accordance with the terms and
conditions of the attached Agreement for the Purchase and Sale of Property.
Escrow Agent does not assume and shall not incur any liability, implied or
otherwise, as a result of any banking institution's dishonor of said check for
any reason, or the performance or non-performance by any party to the agreement.
If the check is dishonored for any reason after being deposited for collection,
Escrow Agent may, at its option, notify all parties to the transaction of said
dishonor, require that any replacement of dishonored check be accomplished with
a Cashier's Check or deposit by wire transfer of funds, and collect any banking
charges incurred by Escrow Agent as a result of said dishonor.

The Earnest Money has been deposited into The Chase Manhattan Bank, Austin,
Texas. Escrow Agent shall not be liable for any interest or other charge on the
funds held and shall assume no liability for the funds until said check is
cleared through regular channels of banking. Escrow Agent shall not refund or
invest the funds until it has received collected funds into its escrow account.
Please be advised of the following critical elements associated with Escrow
Agent's receipt of these funds:

     In the event Purchaser has additional deposit accounts at the above
     referenced banking institution, the Earnest Money will be added to the
     total funds deposited on behalf of Purchaser so as to be included in any
     insurance limits. PLEASE NOTIFY ESCROW AGENT IMMEDIATELY IF THE EARNEST
     MONEY SHOULD BE PLACED WITH ANOTHER BANKING INSTITUTION.

     This Earnest Money has been deposited into a NON-INTEREST BEARING ACCOUNT.
     IF THE PURCHASER SHOULD REQUEST OR THE CONTRACT REQUIRE THE EARNEST MONEY
     TO BE DEPOSITED INTO AN INTEREST BEARING ACCOUNT, ESCROW AGENT MUST BE
     CONTACTED AS ADDITIONAL REQUIREMENTS ARE NECESSARY FOR THE HANDLING OF SUCH
     ACCOUNTS, including Purchaser's execution of a Form W-9 and an
     Authorization to Invest Funds. Service Fees may be incurred for any amounts
     less than $5,000.00.

     Escrow Agent may, at its sole option, require a written release and
     authorization signed by all parties before paying the Earnest Money Deposit
     to any or either party.
