                                    WHEREAS:

A.       Each Company and the Lender wish to provide for the funding
contemplated under the Promissory Note in the amounts set forth in each
respective Promissory Note of even date herewith.

C.       The Guarantor is a Delaware corporation and the Guarantor acknowledges
that without this Guaranty, the Lender would not be willing to enter into the
Promissory Notes.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants set forth herein, and for other good and valuable consideration the
receipt and sufficiency of which is hereby acknowledged, the Guarantor hereby
agrees as follows:

1.       GUARANTY.

         1.1      GUARANTY. The Guarantor, as direct obligor and not merely as a
surety, hereby unconditionally, absolutely, and irrevocably guarantees to the
Lender (i) the full and prompt performance and payment of all of each Company's
obligations under the Promissory Notes and the other Transaction Documents,
(collectively, the "Obligations") and (ii) if any Company should default in the
payment or performance of any of the Obligations, the Guarantor, as direct
obligor and not merely as a surety, shall forthwith pay or perform such
Obligations upon five (5) business days written notice or demand by the Lender
in the manner and on the day required by this Guaranty. In order to effectuate
repayment of the Obligations the Guarantor may take an advance or advances, as
may be necessary, from the Standby Equity Distribution Agreement by and between
<PAGE>

the Guarantor and Cornell Capital Partners, LP, dated November 25, 2003 (the
"Standby Equity Distribution Agreement").

         1.2      CONTINUING GUARANTY. The Guarantor agrees that the obligations
pursuant to this Section 1 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 any Company
         to conform or comply with any term of any of the Transaction Documents;

                  (c) any release or discharge by operation of law of any
         Company 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 Company or the
         Guarantor.

         1.3      DISCHARGE. The Guarantor covenants and agrees that this
Guaranty will not be discharged, except by complete performance of the
obligations contained herein. Notwithstanding anything to the contrary herein,
so long as the outstanding principal amount of the Promissory Notes is zero or
would be made zero simultaneously with the termination hereof, the Guarantor
shall have the right to terminate this Guaranty at any time by providing written
notice of such termination to the Lender. Notwithstanding any to the contrary,
this Guaranty shall be discharged and terminated upon each of the Company's
registration statements being declared effective by the U.S Securities and
Exchange Commission.

         1.4      REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants to the Lender as follows: (a) the Guarantor has full
power, right and authority to enter into and perform his obligations under this
Guaranty, and this Guaranty has been duly executed and delivered by the
Guarantor and constitutes the valid and binding obligation of the Guarantor and

execution, delivery and performance by the Guarantor of this Guaranty and the
consummation by the Guarantor of the transactions contemplated hereby. Neither
the execution nor delivery of this Guaranty by the Guarantor nor the performance

provision of any law, statute, rule, regulation, order, permit, judgment,
ruling, injunction, decree or other decision (collectively, "Rules") of any
