         SECTION 8.2. ACCESS TO PROPERTIES AND RECORDS. Until the Closing Date,
Patron and the Company will afford to the other party's officers and authorized

                                       16

duties or by obligations pursuant to any listing agreement with any national

         SECTION 9.5. SPECIFIC PERFORMANCE. Each party hereto acknowledges and

party hereto or, in the case of a waiver, by the party entitled to the benefit
of the terms being waived.

declared invalid or unenforceable by a court of competent jurisdiction in any

                                       19
<PAGE>

this Agreement shall remain binding on the parties hereto (so long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner adverse to any party). Upon such determination, the
parties shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in a mutually
acceptable manner in order that the transactions contemplated hereby be
consummated as originally contemplated to the greatest extent possible.

         SECTION 9.9. NO THIRD PARTY BENEFICIARIES. This Agreement is for the
benefit of the parties hereto and is not intended to confer upon any other
Person any rights or remedies hereunder.
