                              AFFIRMATIVE COVENANTS

expense of Borrower, to participate in or, at Lender's election, assume the
defense or prosecution of such suit, action, or proceeding, and in the latter
event Borrower may employ counsel and participate therein. Lender shall have the
right to adjust, settle, or compromise any claim, suit, or judgment after notice
to Borrower, unless Borrower desires to litigate such claim, defend such suit,
or appeal such judgment and simultaneously therewith deposits with Lender
additional collateral security sufficient to pay any judgment rendered, with
interest, costs, reasonable legal fees and expenses; and the right of Lender to
indemnification under this Agreement shall extend to any money paid by Lender in
settlement or compromise of any such claims, suits, and judgments in good faith,

Lender against Borrower for breach of Borrower's covenant of indemnity herein
contained, separate suits may be brought as causes of action accrue, without
prejudice or bar to the bringing of subsequent suits on any other cause or
causes of action, whether theretofore or thereafter accruing.

cure within such twenty (20) day period and thereafter diligently pursues such
cure to its completion);

                  6.1.3. Borrower shall become insolvent or unable to pay its

the provisions of this Agreement shall control over the provisions of any other

the agreements of the parties hereto with respect to the subject matter of each
thereof and supersede all prior or contemporaneous discussions and agreements
with respect to such subject matter.

of this Agreement, the Note or any other Loan Document shall be effective only
if set forth in a written instrument signed by Lender and Borrower.

periods required by the Note and all Loan Documents shall run concurrently and
not successively.

         7.5. Survival. The terms of this Agreement and all agreements,
representations, warranties and covenants made by Borrower in any other Loan
Document shall survive the issuance and payment of the Note and shall continue
as long as any portion of the Indebtedness shall remain outstanding and unpaid;
provided, however, that the covenants set forth in Sections 5.2, 7.7 and 7.8
hereof and all other covenants of Borrower to indemnify Lender shall survive the
payment of the Indebtedness. Borrower hereby acknowledges that Lender has
relied, and will rely, upon the foregoing in making the Loans.

         7.6. Successors and Assigns; Governing Law. This Agreement shall be
binding upon and inure to the benefit of the respective successors and assigns
of the parties hereto; provided, however that Borrower shall not assign this

RELATIONSHIP EVIDENCED HEREBY, BORROWER HEREBY IRREVOCABLY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED IN BROWARD
COUNTY OR ANY CONTIGUOUS COUNTY IN THE STATE OF FLORIDA WHERE LENDER MAINTAINS
AN OFFICE AND AGREES NOT TO RAISE ANY OBJECTION TO SUCH JURISDICTION OR TO THE
LAYING OR MAINTAINING OF THE VENUE OF ANY SUCH PROCEEDING IN SUCH COUNTY.
BORROWER AGREES THAT SERVICE OF PROCESS IN ANY SUCH PROCEEDING MAY BE DULY
EFFECTED UPON IT BY MAILING A COPY THEREOF, BY REGISTERED MAIL, POSTAGE PREPAID,
TO BORROWER.

         7.8. Waiver of Jury Trial. BORROWER AND LENDER, AFTER CONSULTATION WITH
THEIR RESPECTIVE COUNSEL, EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY
ACTIONS BROUGHT BY ANY PARTY WITH RESPECT TO THIS AGREEMENT OR THE INDEBTEDNESS.

         7.9. Excess Payments. If Borrower shall pay any interest under the
terms of this Agreement or the Note at a rate higher than the maximum rate
allowed by applicable law, then such excess payment shall be credited as a
payment of principal on the Loans, unless Borrower notifies Lender in writing to
return the excess payment to Borrower.

         7.10. Partial Invalidity. If any provision of this Agreement shall for
any reason be held to be invalid or unenforceable, such invalidity or
unenforceability shall not affect any other provision hereof, but this Agreement
shall be construed as if such invalid or unenforceable provision had never been
contained herein.

         7.11. Compliance with Rules. Lender shall not be required by operation
or effect of any provision of this Agreement to violate any statute or
regulation under state or federal law, including all Rules.

         7.12. Headings. The heading of any Article or Section contained in this
Agreement is for convenience of reference only and shall not be deemed to
