         The waiver by the Payee or other holder of this Promissory Note of the
Maker's prompt and complete performance of, or default under, any provision of
this Promissory Note shall not operate nor be construed as a waiver of any
subsequent breach or default and the failure by the Payee or other holder hereof
to exercise any right or remedy which he may possess hereunder shall not operate
nor be construed as a bar to the exercise of any such right or remedy upon the
occurrence of any subsequent breach or default.

         This Promissory Note shall be governed by, and shall be construed and
interpreted in accordance with, the laws of the State of Florida. This
Promissory Note may not be modified or amended, except by a written instrument
executed by the Maker and the Payee or other holder hereof.

          Any suit for the collection of any amount, whether principal, interest
or otherwise, which shall have become due and payable under this Promissory Note
shall be brought only in the Circuit Court of Miami-Dade County, Florida, and
the Maker hereby knowingly, voluntarily and intentionally submits to the
jurisdiction and venue of such Court. In any suit for the collection of any
amount, whether principal, interest or otherwise, which shall have become due
and payable under this Promissory Note, the Maker knowingly, voluntarily and
intentionally waives any right which it may have to a trial by jury. The Maker
acknowledges that the provisions of this paragraph constitute a material
inducement for the Payee to extend the credit to the Maker evidenced by this
Promissory Note, and that but for the inclusion of such provisions in this
Promissory Note the Payee would not have extended such credit to the Maker.

         IN WITNESS WHEREOF, the Maker, by and through its undersigned officer
thereunto duly authorized, has executed and delivered this Promissory Note as of
August 1, 2001.

                                   SECTION 12
                                  INFRINGEMENT

12.1 In the event either Party to this Agreement shall learn of the substantial
infringement of any of Licensor's Patent Rights, that Party shall notify the
other Party in writing of such infringement and shall provide such other Party
with reasonable evidence of such infringement.

12.2 The Parties shall use their best efforts in cooperating with each other to
terminate such infringement without litigation. Upon their determination that
infringement exists, Licensor shall formally notify the infringing party of
Licensor's determination that infringement exists.

12.3 If the efforts of the Parties are not successful in abating the
infringement within 90 days after the infringer has been formally notified of
infringement by the Licensor, Licensor shall have the right to:

         A. commence suit on its own;
         B. join with Licensee in such suit; or
         C. refuse to participate in such suit,

and Licensor shall give notice in writing to Licensee within 10 business days
after such 90 day period of its election. Licensee may bring suit for patent
infringement only if Licensor elects not to commence or join in any suit other
than as nominal party plaintiff and if the infringement occurred during the
period and in a country where Licensee had exclusive rights under this
Agreement.

12.4 If Licensor elects not to commence or join in any suit other than as a
nominal party plaintiff and if Licensee brings suit against a third party for
infringement of Licensor's Patent Rights, then Licensee's obligation to pay any
unpaid fees as provided for herein shall be modified as follows:

         A. Following the later of: (i) Licensor's election not to commence or
join an infringement suit; and (ii) Licensee's commencement of such suit,
Licensee may postpone paying the fee(s) which would otherwise be due for that
period pending the outcome of such litigation and as further described below;

         B. If the decision of the court or tribunal is that Licensor's Patent
Rights had not been infringed and such decision is rendered within the time
period that fees are still required to be paid by Licensee to Licensor pursuant
to the time schedule set forth in Section 4 hereof, then Licensee shall
recommence paying the balance of the fees, if any, described therein and adopt
the time schedule for such remaining payments, if any, commencing with the day
following the decision of the court or tribunal; if the decision of the court or
tribunal is that Licensor's Patent

                                        7

<PAGE>

Rights had been infringed, then Licensee shall not be required to pay any
additional fees to the Licensor.

12.5 Such legal action as is decided upon shall be at the expense of the Party
on account of whom suit is brought and all recoveries recovered thereby shall
belong to such Party, provided that legal action brought jointly by Licensor and
Licensee and fully participated in by both shall be at the joint expense of the
Parties and all recoveries shall be shared by them in proportion to the expenses
paid by each.

12.6 Each party agrees to cooperate with the other in litigation proceedings
concerning infringement instituted hereunder but at the expense of the Party on
account of whom suit is brought. Such litigation shall be controlled by the
party bringing the suit, except that Licensor shall control the suit if brought
jointly. Licensor may be represented by counsel of its choice pursuant to
Licensor's determination in any suit brought by Licensee.

12.7 Licensor shall not settle or compromise any suit which Licensor controls
which affects any of Licensee's rights or obligations hereunder without
Licensee's prior written consent, which may be withheld by Licensee in its sole
discretion and without any liability of Licensee to Licensor in connection
therewith.

                                   SECTION 13
                                     WAIVER

13.1 No waiver by either Party hereto of any breach or default of any of the
representations, warranties, covenants or agreements herein shall be deemed a
waiver as to any subsequent and/or similar breach or default.

                                   SECTION 14
                              LICENSE RESTRICTIONS

14.1 The rights and privileges granted to Licensee are each and all expressly
conditioned upon the timely performance on the part of Licensee of every
requirement contained herein. Each of such conditions and restrictions is a
specific license restriction.

                                   SECTION 15
                                  ASSIGNABILITY

15.1 This Agreement is binding upon and shall inure to the benefit of each of
Licensor and Licensee and their respective successors and permitted assigns.
This Agreement shall not be assignable by Licensor or Licensee in whole or in
part without the prior written consent of the other party, which consent shall
not be unreasonably withheld.

16.1 Licensee, at its sole cost and expense, shall insure its activities in
connection with this Agreement and obtain, keep in force and maintain general
commercial liability insurance in such amounts as Licensee deems reasonable.

16.2 Licensor disclaims any and all liability for special, incidental, or
consequential damages (including loss of profit) arising out of this Agreement
or with respect to the installation, use operation or support of the Licensed
Products or any update of the Licensed Products, even if the Licensor has been
apprised of the possibility of such damages.

16.3 Licensee specifically agrees that any liability on the part of Licensor
arising from breach of warranty, breach of contract, negligence, strict
liability in tort, or any other legal theory shall not exceed any amounts paid
by Licensee in fees for the use and maintenance of the Licensed Products.

                                   SECTION 17
