4. TITLE; FILING. Corporation warrants that, except as previously disclosed in
writing to Secured Party, it is the owner of the Collateral free and clear of
all liens, claims, and encumbrances of whatever kind or nature. Corporation
covenants that so long as any portion of the Obligations remains unpaid,
Corporation will not execute or file a financing statement or security agreement
covering the Collateral to anyone other than Secured Party, except in the
ordinary course of business or as otherwise allowed. Corporation agrees to sign
and deliver one or more financing statements or supplements thereto or other
instruments as Secured Party may from time to time require to comply with the
Uniform Commercial Code or other applicable law to preserve, protect and enforce
the security interest of Secured Party and to pay all costs of filing such
statements or instruments. In addition, Corporation shall promptly file a
financing statement to perfect Secured Party's interest in the Collateral.

security interests; pay when due all taxes, license fees, and other charges upon
the Collateral or upon Corporation's business, property or the income therefrom;
and not misuse, conceal or in any way use or dispose of the Collateral
unlawfully or contrary to the provisions of this Security Agreement or of any
insurance coverage. Loss of, damage to, or uncollectability of the Collateral or
any part thereof will not release Corporation from any of its obligations
hereunder.

6. DEFAULT. A default hereunder will occur if any of the following Events of
Default as defined under Article 7 of the Debenture shall occur. Waiver of any
default will not constitute a waiver of any other or subsequent default.

7. REMEDIES. Upon the occurrence of any default hereunder at any time
thereafter, all of the Obligations will, at the election of Secured Party and
without notice of such election, or demand for payment, become immediately due
and payable and Secured Party will have the remedies of a secured party under
the Florida Uniform Commercial Code or other applicable law.

8. GENERAL. The wavier by Secured Party of any breach of any provision of this
Security Agreement or warranty or representation herein set forth will not be
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
the remainder. All words used herein will be construed to be of such gender and
number as the circumstances require. This Security Agreement binds Corporation,
its successors and assigns, and inures to the benefit of Secured Party, its
successors and assigns.
