Section 7. Remedies for Failure to Close.
-----------------------------------------

     7.1 Buyer. If on the Closing Date this Agreement is in full force and
effect, Buyer is not otherwise in default and Sellers fail to convey the
Property to Buyer in accordance with this Agreement, then in such event, Buyer
may elect as its remedy to either: (a) terminate this Agreement, in which event
the Earnest Money and the Contingency Deposit shall be immediately returned to
Buyer; or (b) continue this Agreement and prosecute a claim for specific
performance of this Agreement.

     7.2 Seller. If on the Closing Date this Agreement is in full force and
effect, Sellers are not otherwise in default and Buyer fails to purchase the
Property in accordance with this Agreement, then in such event, Sellers shall be
entitled to terminate this Agreement and retain the Earnest Money and the
Contingency Deposit, if made (collectively referred to in this Section 7.2 as
the "Deposits"), as liquidated damages. Seller shall not be entitled to any
other damages for Buyer's default under this Agreement, provided Buyer does not
dispute or prevent the Seller's retention of the Deposits. The parties
acknowledge and agree that it would be difficult and speculative to determine
the actual damages suffered by Sellers in the event of Buyer's default.
Therefore, the parties agree to liquidate the amount of Sellers' damages to an
amount equal to the Deposits, provided Buyer does not dispute or prevent the
Sellers' retention of the Deposits. If Buyer disputes or prevents Sellers'
retention of the Deposits, Sellers shall be entitled to pursue any remedies and
damages available at law, including forfeiture of the Deposits.
