       The Note and Loan Documents provide that the Borrower shall from time to
time deliver to the Bank certain information, reports, representations,
certifications and warranties.  For purposes of such performance in favor of the
Bank and to establish the threshold of the knowledge or notice that the Borrower

deemed to have notice of a fact when (a) Borrower has actual knowledge of it; or
(b) Borrower has received a notice or notification of it; or (c) from all of the
facts or circumstances known to the Borrower at the time in question, the
Borrower has reason to know that it exists.

       The Borrower shall be deemed to "know" or to have "knowledge" of a fact
when the Borrower has actual knowledge of it.  "Discover" or "learn" or a word
or phrase of similar import refers to knowledge rather than to reason to know.
The time and circumstances under which a notice or notification may cease to be
effective are not determined by the Uniform Commercial Code of Florida.  All
other terms shall be as defined in the Uniform Commerical Code of the State of
Florida.

                                15. DEFINITIONS

       It is the intent that Discounted Leases and the equipment which is the
subject of such Discounted Leases not be a part of the Collateral securing this
Loan.  Provided, however, should Borrower present a Discounted Lease to Bank as
Collateral for a draw upon the Loan, Bank shall determine on a case by case
basis the amounts to be loaned under the Line of Credit and it shall be
conditioned upon the Bank's underwriting requirements existing at the time of
the request, including but not limited to, acquiring a first security interest
in the Discounted Lease and the equipment which is the subject of such
Discounted Lease.

                         18. DELIVERY AND ACCEPTANCE.
