hereunder.

and payable and Secured Party will have the remedies of a secured party under

construed as a waiver of any subsequent breach. The failure to exercise any
right hereunder by Secured Party will not operate as a waiver of such night. All
rights and remedies herein provided are cumulative. Corporation may not assign
its rights or delegate its duties hereunder without Secured Party's written
consent. This Security Agreement may not be altered or amended except by a
writing signed by all the parties hereto. This Security Agreement will be
governed by and construed and interpreted in accordance with the laws of the
State of Florida. Any provision hereof found to be invalid will not invalidate
