        written notice to the Borrower to remedy such condition or situation.

SECTION 12. DEFAULT REMEDIES.

                (i)     Lender shall retain the right to terminate making any
                        further advances of the Loan at any time thereafter,
                        without notice, and until all Obligations are satisfied
                        in full, such termination shall not affect the duties,
                        covenants and liabilities of Borrower hereunder and all
                        the terms, conditions and provisions hereof relating
                        thereto shall continue to be fully operative until all
                        transactions entered into and Obligations have been
                        fully satisfied;

                (ii)    All or any portion of Obligations due or to become due
                        whether under this Agreement or otherwise, shall, at the
                        option of Lender, without notice, demand, presentment or
                        dishonor, all of which Borrower hereby waives, become at
                        once due and payable, and Lender shall thereupon have
                        all the rights and remedies of a secured party under the
                        Uniform Commercial Code as adopted by the State of
                        Florida;

                (iii)   Lender may also, with or without proceeding with sale or
                        foreclosure or demanding payment of a debt owing by
                        Borrower to Lender, without notice, terminate further
                        performance under this Agreement and may declare all
                        outstanding amounts under the Loan Documents due and
                        payable and proceed against the Collateral whether or
                        not in the possession of Lender.; and

                (iv)    To the extent either Borrower or any guarantor makes a
                        payment or payments to Lender which payment or payments
                        or any part thereof are subsequently invalidated,
                        declared to be fraudulent or preferential, set aside or
                        required to be repaid to a trustee, receiver or any
                        other party under any bankruptcy act, state or federal
                        law, common law or equitable cause, then, to the extent
                        of such payment or repayment, the Obligation(s) or part
                        thereof intended to be satisfied shall be revived and
                        continued in full force and effect as if such payment
                        had not been made.

b)      Any failure or delay of Lender to exercise or enforce any rights, liens,
        powers or remedies hereunder or under any of the aforesaid agreements or
        other documents or security or Collateral shall not operate as a waiver
        of such liens, rights, powers and remedies, but all such liens, rights,
        powers and remedies shall continue in full force and effect until all
        loans and advances and all Obligations owing or to become owing from
        Borrower to Lender shall have been fully satisfied and all liens,
        rights, powers and remedies herein provided are cumulative and none is
        exclusive.

c)      Lender may exercise any right or remedy it has under the Promissory Note
        which rights and remedies thereunder are not limited hereby.

SECTION 13. MISCELLANEOUS

a)      Further Assurances. From time to time, Borrower will execute and deliver
        to Lender such additional documents and will provide such additional
        information as Lender may reasonably require to carry out the terms of
        this Agreement and be informed of Borrower's status and affairs.

b)      Payment. The Borrower agrees that as long as the Loan Documents are in
        full force and effect, it will make all payments on each Payment Date,
        when due, by check duly mailed or delivered to Lender at the address
        indicated in the Notice section of this Agreement, or at such other
        place as Lender may designate to the Borrower in writing.

c)      Successors and Assigns. This Agreement shall bind and inure to the
        benefit of the respective successors and assigns of the parties hereto.

d)      Waiver by Lender. Lender shall have the right at all times to enforce
        the provisions of this Agreement and any other Loan Document executed
        pursuant hereto in accordance with the terms hereof and thereof,
        notwithstanding any conduct or custom on the part of Lender in
        refraining from so doing at any time. The failure of Lender at any time
        to enforce its rights under such provisions, in accordance with the same
        shall not be construed as having created a custom in any way or manner
        contrary to specific provisions of this Agreement or as having in any
        way or manner modified or waived the same. All rights and remedies of
        Lender are cumulative and concurrent and the exercise of one right or
        remedy shall not be deemed a waiver or release of any other right or
        remedy.

e)      Costs/Expenses. Pay all reasonable costs and expenses related to the
        transactions contemplated hereby including but not limited to,
        out-of-pocket expenses for payment of documentary stamp taxes,
        intangible taxes, recording and filing fees, surveys, title insurance
        premium, legal fees and expenses of counsel appointed by the Lender, any
        applicable sales tax together with any interest and penalties for the
        late payment thereof, all of which amounts shall be payable at the time
        of the execution of this Agreement or upon demand in the event they are
        hereafter incurred.

f)      Attorney's Fees. If either of the Parties hereto should bring a Court
        action alleging breach of this Agreement or seeking to enforce, rescind,
        renounce, declare void or terminate this Agreement or any provisions
        thereof, the prevailing party shall be entitled to recover all of its
        legal expenses, including reasonable attorney's fees and costs
        (including legal expenses for any appeals taken), and to have the same
        awarded as part of the judgment in the proceeding in which such legal
        expenses and attorney's fees were incurred.

        matter of this Agreement are hereby canceled and terminated, and all
        Parties agree that there are no representations or warranties other than
        those set forth herein.

k)      Invalidation. Should any part of this Agreement for any reason be
        declared invalid, such decision shall not effect the validity of any
        remaining portion, which remaining portion shall remain in full force
