Guarantors have agreed, jointly and severally, to provide a full and
unconditional guaranty of the payment and performance obligations of Borrower
under the Bendes Promissory Note;

         NOW, THEREFORE, in consideration of the Loan, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Guarantors hereby unconditionally guarantee to Bendes, and its
endorsees, transferees and assigns the punctual payment when due, whether by

Borrower to Bendes pursuant to the Bendes Promissory Note.

         1.1. RECITALS. The above recitals are true and correct and are
incorporated herein, in their entirety, by this reference.

         1.2. DEFINITIONS. All capitalized terms contained herein shall have the
meaning ascribed to them in the Loan Agreement entered into between, among
others, the Borrower and the Secured Party, dated as of April 16, 2004 (the

                                   ARTICLE 2.
                                    GUARANTY

         2.1. GUARANTY. The Guarantors, as direct obligors and not merely as
sureties, hereby unconditionally, absolutely, and irrevocably guarantee, jointly
and severally, to Bendes (i) that the Borrower shall repay to Bendes the
principal amount plus accrued interest within the period of time provided in the
Bendes Promissory Note, and all other amounts due to Bendes under the Bendes
Promissory Note and other Transaction Documents, including, without limitation,
all reasonable fees and costs incurred by Bendes in collecting or securing or
attempting to collect or secure the Bendes Promissory Note, including reasonable
attorneys' fees and expenses, whether or not involving litigation and/or

Borrower should default in the payment or performance of any of the Obligations,
the Guarantors, as direct obligors and not merely as sureties, shall forthwith
pay or perform such Obligations without notice or demand by Bendes in the manner
and on the day required by this Guaranty.

         2.2. CONTINUING GUARANTY. The Guarantors agree that their obligations
pursuant to this Section 2 are unconditional, absolute, and irrevocable and
shall not be released, discharged or affected in any way by any circumstances or
condition, including without limitation:

                  (a) any amendment or modification or other change to any of
the Transaction Documents;

                  (b) any failure, omission or delay on the part of the Borrower
to conform or comply with any term of any of the Transaction Documents;

                  (c) any release or discharge by operation of law of the
Borrower or any Guarantor from any obligation or agreement contained in any of
the Transaction Documents or this Guaranty; and

                  (d) any other occurrence, circumstance, happening or event,
whether similar or dissimilar to the foregoing and whether foreseen or
unforeseen, which otherwise might constitute a legal or equitable defense or
discharge of the liabilities of a guarantor or surety or which otherwise might
limit recourse against the Borrower or the Guarantors.

         2.3. GUARANTY OF PAYMENT AND NOT OF COLLECTION. The liability of the
Guarantors shall be continuing, direct and immediate and not conditional or
contingent upon either the pursuit of any remedies against the Borrower or any
other person or foreclosure of any security interests or liens available to
Bendes, its successors, endorsees or assigns. Bendes may accept any payment(s),
plan for adjustment of debts, plan of reorganization or liquidation, or plan of
composition or extension proposed by, or on behalf of, the Borrower or any other
guarantor without in any way affecting or discharging the liability of the
Guarantors. If the Obligations are partially paid, the Guarantors shall remain
liable for any balance of such Obligations. This Guaranty shall be revived and
reinstated in the event any payment received by Bendes on any Obligation is
required to be repaid or rescinded under present or future federal or state law
or regulation relating to bankruptcy, insolvency or other relief of debtors.

         2.4. DISCHARGE. The Guarantors covenant and agree that this Guaranty
will not be discharged, except by complete performance of its obligations
contained herein. Upon the occurrence of no amounts of principal, interest or
other amounts whatsoever being due to Bendes under the Bendes Promissory Note
and the Transaction Documents or being made zero simultaneously with the
termination hereof, the Guarantors shall have the right to terminate this
Guaranty by providing written notice of such termination to Bendes.

         2.5. COSTS AND EXPENSES. Without limiting any obligation of the
Guarantors hereunder, the Guarantors agree to pay all reasonable fees and costs
incurred by Bendes in collecting or securing or attempting to collect or secure
this Guaranty, the Bendes Promissory Note or the Transaction Documents,
including, without limitation, reasonable attorneys' fees and expenses, whether
or not involving litigation and/or appellate or bankruptcy proceedings.

unenforceable, the remaining provisions of this Guaranty will nevertheless be
valid and enforceable and will remain in full force and effect. Any provision of
this Guaranty that is held invalid or unenforceable by a court of competent

and enforceable and as so modified will remain in full force and effect.

         3.4. AMENDMENT AND WAIVER. This Guaranty may be amended, or any
provision of this Guaranty may be waived, provided that any such amendment or
waiver will be binding on a party hereto only if such amendment or waiver is set

hereto of a breach of any provision of this Guaranty shall not operate or be
construed as a waiver of any other breach.

         3.5. HEADINGS. The subject headings of Articles and Sections of this
Guaranty are included for purposes of convenience only and shall not affect the
construction or interpretation of any of its provisions.

         3.6. ASSIGNMENT. Bendes may not assign this Guaranty without the
written consent of the Guarantors. This Guaranty will be binding upon and inure
to the benefit of the parties hereto and their respective successors and
permitted assigns, but will not be assignable or delegable by the Guarantors.
Except as otherwise provided herein, this Guaranty shall bind and inure to the
benefit of and be enforceable by the parties and their permitted successors and

such other actions as the other parties may reasonably request in order to
consummate the transactions provided for herein and to accomplish the purposes
of this Guaranty.

         3.8. THIRD PARTIES. Nothing herein expressed or implied is intended or
shall be construed to confer upon or give to any person or entity, other than
the stated beneficiaries of this Guaranty and their respective permitted
successors and assigns, any rights or remedies under or by reason of this
Guaranty.

         3.9. NO STRICT CONSTRUCTION. The language used in this Guaranty will be
deemed to be the language chosen by the parties hereto to express their mutual
intent, and no rule of strict construction will be applied against any party
hereto.

         3.10. EVENT OF DEFAULT. For purposes of this Guaranty, an event of
default shall be deemed to have occurred hereunder:

                  (a) If the Borrower should default under the Bendes Promissory
Note, in the payment or performance of any of the Obligations or under any of
the Transaction Documents, the Guarantor shall fail for any reason or for no
reason, to forthwith pay or perform such Obligations without notice or demand by
Bendes in the manner and on the day required this Guaranty;

                  (b) if any of the Guarantors make an assignment for the
benefit of creditors or admits in writing its inability to pay its debts
generally as they become due; or an order, judgment or decree is entered
adjudicating any of the Guarantors bankrupt or insolvent; or any order for
relief with respect to any of the Guarantors is entered under any bankruptcy or
insolvency laws; or any of the Guarantors petitions or applies to any tribunal
for the appointment of a custodian, trustee, receiver or liquidator of such
Guarantor of any substantial part of the assets of the Guarantor, or commences
any proceeding relating to any of the Guarantors under any bankruptcy
reorganization, arrangement, insolvency, readjustment of debt, dissolution or
liquidation law of any jurisdiction; or any such petition or application is
filed, or any such proceeding is commenced, against any of the Guarantors; or

                  (c) if any of the Guarantors should default in any other
obligation set forth in this Guaranty or the Transaction Documents.

         Upon an event of default, all of the obligations of the Guarantors
hereunder shall be immediately due and payable without any action on the part of
Bendes, and Bendes shall be entitled to seek and institute any and all remedies
available to it. No remedy conferred under this Guaranty upon Bendes is intended
to be exclusive of any other remedy available to Bendes, pursuant to the terms
of this Guaranty or otherwise. No single or partial exercise by Bendes of any
right, power or remedy hereunder shall preclude any other or further exercise
thereof. The failure of Bendes to exercise any right or remedy under this
Guaranty or otherwise, or delay in exercising such right or remedy, shall not
operate as a waiver thereof.

         3.11. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF.
Bendes' remedies provided in this Guaranty shall be cumulative and in addition
to all other remedies available to the Bendes under this Guaranty or otherwise,
at law or in equity (including a decree of specific performance and/or other
injunctive relief), no remedy of Bendes contained herein shall be deemed a
waiver of compliance with the provisions giving rise to such remedy and nothing
herein shall limit Bendes' right to pursue actual damages for any failure by any
of the Guarantors to comply with the terms of this Guaranty. Every right and
remedy of any of the Guarantors under any document executed in connection with
this transaction, including but not limited to this Guaranty and the Transaction
Documents or under applicable law may be exercised from time to time and as
often as may be deemed expedient by Bendes. Each of the Guarantors acknowledges
that a breach by him of his obligations hereunder will cause irreparable harm to

                                       5
<PAGE>

Bendes and that the remedy at law for any such breach may be inadequate. The
Guarantors therefore agree that, in the event of any such breach or threatened
breach, Bendes shall be entitled, in addition to all other available remedies,
to an injunction restraining any breach, and specific performance without the
necessity of showing economic loss and without any bond or other security being
required.

         3.12. GOVERNING LAW; JURISDICTION. This Guaranty and all transactions
contemplated by this Guaranty shall be governed by and construed and enforced in
accordance with the laws of the State of Florida, without regard to principles
of conflicts of law. The parties hereto hereby agree to the exclusive
jurisdiction of the state courts situated in Miami-Dade County and the parties
hereby waive any objection which they may have to the laying of venue of any
such proceeding in such court and waive any claim of inconvenient forum with
respect to such venue. The parties hereto further agree that service of process,
relating to an action arising hereunder, pursuant to the notice provision set
forth in this Guaranty shall be sufficient and hereby waive any claim for
insufficiency of process as a result of a party's use of such method of service.

         3.13. WAIVER OF JURY TRIAL. AS A MATERIAL INDUCEMENT FOR BENDES TO LOAN
TO THE BORROWER THE MONIES UNDER THE PROMISSORY NOTE AND TO ACCEPT THIS
GUARANTY, THE GUARANTORS HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING RELATED IN ANY WAY TO THIS AGREEMENT AND/OR ANY AND ALL OF THE OTHER
DOCUMENTS ASSOCIATED WITH THIS TRANSACTION.

         3.14. ENTIRE AGREEMENT. This Guaranty (including the recitals hereto)
sets forth the entire understanding of the parties with respect to the subject
matter hereof, and shall not be modified or affected by any offer, proposal,
statement or representation, oral or written, made by or for any party in
connection with the negotiation of the terms hereof, and may be modified only by
instruments signed by all of the parties hereto.

         IN WITNESS WHEREOF, the Guarantors have caused this Guaranty to be
signed as of the date first written above.
