<PAGE>

liquidated damages and thereafter the parties hereto shall have no further
rights or obligations hereunder whatsoever. It is hereby agreed that Seller's
damages will be difficult to ascertain and that the Earnest Money constitutes a
reasonable liquidation thereof and is intended not as a penalty, but as fully
liquidated damages. Seller agrees that in the event of default by Purchaser, it
shall not initiate any proceeding to recover damages from Purchaser, but shall
limit its recovery to the retention of the Earnest Money.

     19.  Seller's Default.  In the event of default by Seller under the terms
          ----------------
of this Agreement, including, without limitation, the failure of Seller to cure
any title defects or objections, except as otherwise specifically set forth
herein, at Purchaser's option: (i) Purchaser shall have the right to terminate
this Agreement by giving written notice of such termination to Seller, whereupon
Escrow Agent shall promptly refund all Earnest Money to Purchaser, and Purchaser
and Seller shall have no further rights, obligations, or liabilities hereunder,
except as may be expressly provided to the contrary herein; or (ii) Purchaser
shall have the right to accept title to the Property subject to such defects and
objections with no reduction in the Purchase Price, in which event such defects
and objections shall be deemed "Permitted Exceptions"; or (iii) Purchaser may
elect to seek specific performance of this Agreement, provided that, except as
provided in the next sentence, Seller shall not be required to expend more than
$250,000 in connection with any such performance. Notwithstanding the foregoing,
if any such defects or objections arose by, through, or under Seller or if any
such defects or objections consist of taxes, mortgages, deeds of trust, deeds to
secure debt, mechanic's or materialman's liens, or other such monetary
encumbrances, Purchaser shall have the right to cure such defects or objections,
in which event the proceeds due Seller at Closing shall be reduced by an amount
equal to the costs and expenses incurred by Purchaser in connection with the
curing of such defects or objections, and upon such curing, the Closing hereof
shall proceed in accordance with the terms of this Agreement.

     20.  Condemnation.  If, prior to the Closing, all or any part of the
          ------------
Property is subjected to a bona fide threat of condemnation by a body having the
power of eminent domain or is taken by eminent domain or condemnation (or sale
in lieu thereof), or if Seller has received notice that any condemnation action
or proceeding with respect to the Property is contemplated by a body having the
power of eminent domain, 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 thirty (30) 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 20, 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

                                      12
<PAGE>

that have been or that may thereafter be made for such taking.

     21.  Damage or Destruction.  If any of the Improvements shall be destroyed
          ---------------------
or damaged prior to the Closing, and the estimated cost of repair or replacement
exceeds $250,000.00, Purchaser may, by written notice given to Seller within
twenty (20) 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 21, or has no right to terminate this Agreement
(because the damage or destruction does not exceed $250,000.00), 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 (less amounts of
insurance theretofore received and applied by Seller to restoration) plus the
amount of any deductible. If the amount of said casualty or rent loss insurance
proceeds is not settled by the date of Closing, Seller shall execute at Closing
all proofs of loss, assignments of claim, and other similar instruments to
ensure that Purchaser shall receive all of Seller's right, title, and interest
in and under said insurance proceeds.

     22.  Hazardous Substances.  Seller hereby warrants and represents, to the
          --------------------
best of Seller's knowledge and except as disclosed in that certain Phase I

or warranty contained in this Paragraph.

discussed this Agreement or the subject matter hereof with any real estate
broker or agent other than Broker so as to create any legal right in any such
broker or agent to claim a real estate commission with respect to the conveyance
of the Property contemplated by this Agreement. Seller shall and does hereby
indemnify and hold harmless Purchaser from and against any claim, whether or not
meritorious, for any real estate sales commission, finder's fees, or like

any act or agreement of Seller, including any claim asserted by Brokers and any

of the parties hereto, and no representations, inducements, promises, or
agreements, oral or otherwise, between the parties not embodied herein shall be
of any force or effect. Any amendment to this Agreement shall not be binding
upon the parties hereto unless such amendment is in writing and executed by all
parties hereto. The provisions of this Agreement shall inure to the benefit of

expenses, except for its gross negligence or willful misconduct, and it shall
accordingly not incur any such liability with respect to any action taken or
omitted in good faith upon advice of its counsel or in reliance upon any
instrument, including any written notice or instruction provided for in this
Agreement, not only as to its due execution and the validity and effectiveness
of its provision, but also as to the truth and accuracy of any information
contained therein that Escrow Agent shall in good faith believe to be genuine,
to have been signed or presented by a proper person and to conform to the
provisions of this Agreement.  Seller and Purchaser hereby agree to indemnify
and hold harmless Escrow Agent against any and all losses, claims, damages,
liabilities and expenses, including reasonable costs of investigation and legal
fees and disbursements, that may be imposed upon Escrow Agent or incurred by
Escrow Agent in connection with its acceptance or performance of its duties
hereunder as escrow agent, including without limitation, any litigation arising
out of this Agreement.  If any dispute shall arise between Seller and Purchaser
sufficient in the discretion of Escrow Agent to justify its doing so, Escrow
Agent shall be entitled to tender into the registry or custody of the clerk of
the Court for the county in which the Property is located or the clerk for the
United States District Court having jurisdiction over the county in which the
Property is located, any or all money (less any sums required to pay Escrow
