reason or for no reason, terminate this Agreement and receive an immediate
return of the Earnest Money unless on or before the expiration of the Due
Diligence Period, Buyer has determined, to Buyer's sole satisfaction, that the

to Buyer and neither party shall have further obligations to the other. Failure
by Buyer to deliver such notice to Seller prior to the expiration of the Due
Diligence Period shall be deemed to be Buyer's election to terminate the
Agreement.

Commitment and Survey, Buyer shall deliver copies thereof to Seller and during
the Due Diligence Period may notify Seller of any title objections it may have.
Seller shall have ten (10) business days from its receipt of such notice to
respond to Buyer that it (a) will cure or otherwise remove such title objections
prior to Closing or (b) that it will not cure or otherwise remove such title

of time (not to exceed thirty (30) days) in which to complete such cure. Should

is later, to notify Seller whether it will (a) terminate this Agreement and
receive a prompt return of the Earnest Money or (b) proceed under this Agreement
to Closing, without reduction or abatement of the Purchase Price. Seller's lack
of response shall be deemed to be Seller's notice that Seller has elected to
proceed under clause (b) hereof. Buyer's notice that the Project is suitable
made under Section 3.2 hereof shall be deemed an acceptance by Buyer of all
matters related to the title of the Land existing prior to the date of the Title
Commitment.

      (b) In the event the Title Commitment is amended to include new exceptions
that are not set forth in a prior version of the Title Commitment, Buyer shall
have until the later of (i) the expiration of the Due Diligence Period, or (ii)
the date seven (7) days after Buyer's receipt of the amended Title Commitment
and copies of the documents identified in the new exceptions or new
requirements, within which to cancel this Agreement and receive a refund of the
Earnest Money or to provisionally accept the title subject to Seller's agreement
to cause the removal of any disapproved exceptions or objections. If Seller
serves notice to Buyer that Seller does not intend to remove such new exceptions
and objections before Closing, Buyer shall, within ten (10) days thereafter,
notify Seller and Escrow Agent in writing of Buyer's election to either (i)
terminate this Agreement, whereupon the Earnest Money shall be returned to Buyer
and all obligations shall terminate, or (ii) Buyer may waive such objections and
the transaction shall close as scheduled. If written notice of objection to such
new exceptions or requirements is not timely given by Buyer to Seller pursuant
to this Section 3.6(b), then Buyer shall be deemed to have objected to all such
new objections or requirements.

      3.7. Title and Survey Costs. Buyer shall pay any and all costs related to
the Title Commitment and Owner's Policy. Buyer shall pay any and all costs
related to the Survey.

      3.8. Confidentiality. Neither Buyer nor Seller shall make public

contractors, creditors, officers, employees and agents as necessary to perform

                                   ARTICLE VI
                           EMINENT DOMAIN AND CASUALTY

      Seller shall bear all risk of loss, damage or taking of the Project which
may occur prior to Closing, as described in this Article. In the event that,
prior to the Closing Date, all or any portion of the Project is damaged or
destroyed to any extent by fire, earthquake, flood or other cause or casualty or
shall have been affected by condemnation or taking by eminent domain, or shall
be the subject of any condemnation proceeding of which Seller shall have
received actual or constructive notice, or shall be sold by Seller in lieu
thereof, Buyer shall have the option, but not the obligation, to accept the
Project, or such title thereto as Seller can convey, in such condition as the
Project or title may then be, with no reduction in the Purchase Price, but
together with the right to receive the proceeds of any insurance or condemnation
award or sale in lieu of such condemnation proceeding which shall have been or
shall be made in connection with such damage, destruction, condemnation or
taking, as the case may be. Such option must be exercised by Buyer by written
notice to Seller within a reasonable time but in no event later than ten (10)
days following receipt by Buyer of written notice from Seller of such damage,
destruction, condemnation or taking, and if such option is not so exercised,
this Agreement shall thereafter terminate. In the event of termination of this
Agreement pursuant to this Section, the Earnest Money shall be promptly returned
to Buyer and both Parties shall be relieved of all obligations hereunder which
do not expressly survive termination of this Agreement.

                                   ARTICLE VII
                                     DEFAULT

      7.1 Seller's Default. In the event that Seller shall fail to perform any
of Seller's obligations hereunder within the time for or in the manner of
performance herein provided following the expiration of any applicable grace or
cure period, Buyer shall have the right to elect one (1) of the following: (i)
terminate this Agreement in which event the Earnest Money, together with any
interest accrued thereon, shall be refunded to Buyer; (ii) waive such default
and close

                                       10
<PAGE>

under this Agreement; or (iii) seek the specific performance of this Agreement.
Notwithstanding the foregoing, if specific performance is unavailable as a
remedy to Buyer because of Seller's affirmative acts, Buyer shall be entitled to
pursue all rights and remedies available at law or in equity.

      7.2 Buyer's Default. In the event that Buyer shall fail to perform any of
Buyer's obligations hereunder following the expiration of any applicable grace
or cure period, Seller may terminate this Agreement in which event the Earnest
Money, together with all interest accrued thereon, shall be paid to Seller as
Seller's sole remedy for Buyer's default.

      7.3 Right to Cure Defaults. Prior to the exercise by Buyer or Seller of
their respective rights under this Article, the non-defaulting Party shall
provide written notice specifying such default to the other party (the
"Defaulting Party") and the Defaulting Party shall have ten (10) days following
notice to cure such default.

                                  ARTICLE VIII
                                   THE ESCROW

      8.1 Deposit of the Earnest Money. Escrow Agent shall hold the Earnest
Money in a non-interest bearing account in accordance with the terms of this
Agreement; provided, however, if Buyer pays all fees incurred in connection with
the establishment of an interest bearing account and so directs Escrow Agent in
writing, the Earnest Money will be deposited into an interest bearing account.
All checks, money orders or drafts deposited with Escrow Agent under this
Agreement will be processed for collection in the normal course of business.
Escrow Agent may not commingle funds received by it in escrow with funds of
others and may, without limitation, deposit such funds in its trust or escrow
accounts with any reputable Trust Company, Bank, Savings Bank or Savings
Association. Escrow Agent shall not be liable for any loss caused by the
failure, suspension, bankruptcy or dissolution of any such investment vehicle or
fund.

      8.2 No Liability for Certain Acts and Omissions. Escrow Agent shall not be
liable for any loss or damage resulting from the following: (a) any defects or
conditions of title to any property; (b) any defects in the property purchased,
obligations or rights of any tenant or other party in possession, the surrender
of possession or any misrepresentations made by any other party; (c) any
default, error, action or omission of any other party; (d) the expiration of any
time limit or other delay, unless such time limit was known to Escrow Agent and
such loss is solely caused by failure of Escrow Agent to proceed in its ordinary
course of business; (e) lack of authenticity, sufficiency and effectiveness of
any documents delivered to it and lack of genuineness of any signature or
authority of any person to sign any such document; (f) any loss or impairment of
Earnest Money deposited in the course of collection or while on deposit with any
Trust Company, Bank, Savings Bank or Savings Association resulting from failure,
insolvency or suspension of such institution; (g) Escrow Agent complying with
any and all legal process, writs, orders, judgments and decrees of any court
whether issued with or without jurisdiction and whether or not subsequently
vacated, modified, set aside or reversed; (h) Escrow Agent asserting or failing
to assert any cause of action or defense in any judicial, administrative or
other proceeding either in the interest of itself or any other party or parties;
or (i) any good faith act or forbearance by Escrow Agent.

      8.3 Authenticity of Instructions. Escrow Agent shall have no obligation to
inquire into the authenticity of any written instructions delivered to it as
required by this Agreement nor

                                       11
<PAGE>

to inquire as to the genuineness of any signature of authority of any person to
issue such instructions.

      8.4 Disputes. If written notice of default, non-performance or dispute by
or between either Seller or Buyer is given to Escrow Agent, Escrow Agent shall
notify in writing all other parties of the receipt of such notice and shall not
disburse any Earnest Money until Escrow Agent receives written joint
disbursement instructions by both Seller and Buyer or until Escrow Agent
receives an order from a court of competent jurisdiction authorizing or
requiring Escrow Agent to disburse the Earnest Money. If within (15) days from
the date of mailing of such notice by Escrow Agent, a written joint instruction
reply executed by both Seller and Buyer has not been received by Escrow Agent or
a conflicting instruction reply has been received from any party, Escrow Agent
may file an interpleader action to resolve the conflict. Escrow Agent shall be
indemnified, saved and held harmless by the other parties for all of its
expenses, costs and reasonable attorney fees incurred in connection with an
interpleader action and such expenses, costs and fees may be deducted from the
Earnest Money held hereunder.

      8.5 Indemnification. If Escrow Agent is made a party to any judicial,
non-judicial or administrative action, hearing or process based on acts of any
of the other parties hereto and not on the malfeasance and/or gross negligence
of Escrow Agent in performing its duties hereunder and which seeks to attach,
recover or direct disbursement/release of the subject matter of this Agreement,
the expenses, costs and reasonable attorney fees incurred by Escrow Agent in
responding to such action, hearing or process may be deducted from the funds
held hereunder and the parties shall indemnify save and hold Escrow Agent
harmless from said expenses costs and fees so incurred.

                                   ARTICLE IX
                            MISCELLANEOUS PROVISIONS

liabilities arising from a breach of the representation and warranty made by

court costs.

<PAGE>

Buyer from liability under this Agreement. In order for any assignment to be

by Buyer.

      9.6 Time of Essence. Time is of the essence of this Agreement.

      9.7 Unenforceable or Inapplicable Provisions. If any provision hereof is

number of counterparts, each of which will for all purposes be deemed to be an
original, and all of which are identical.

required to the effectiveness and enforceability of this Agreement against such
party following such execution.

      9.12 Further Assurances. In addition to the acts and deeds recited herein
and contemplated to be performed at the Closing, Seller and Buyer agree to
perform such other acts, and to execute and/or deliver such other instruments

Agreement. Further, Seller and Buyer each agree to deliver to the Title Company
affidavits and such other assurances as may reasonably be necessary or required

of 1986, as amended (the "Code"), provided that: (a) the Closing shall not be
delayed or affected by reason of an Exchange nor shall the consummation or
accomplishment of any Exchange be a condition precedent or condition subsequent
to a party's obligations under this Agreement; (b) any party desiring an
Exchange shall effect its Exchange through an assignment of this Agreement, or
its rights under this Agreement, to a qualified intermediary and the other party
shall not be required to take an

<PAGE>

assignment of the purchase agreement for the relinquished or replacement
property or be required to acquire or hold title to any real property for
purposes of consummating such Exchange; and (c) the party desiring an Exchange

Exchange desired by the other party (i) have its rights under this Agreement
affected or diminished in any manner or (ii) be responsible for compliance with
or be deemed to have warranted to the other party that such party's Exchange in
fact complies with Section 1031 of the Code.

      9.15 Escrow Cancellation Charges. If escrow fails to close because of
Seller's default, Seller shall be liable for any reasonable cancellation charges
of Escrow Agent. If escrow fails to close because of Buyer's default, Buyer
shall be liable for any reasonable cancellation charges of Escrow Agent. If

costs, loss, liability, damage, expenses, demand, action or cause of action
arising from or related to the Lease arising from events occurring prior to
Closing.
