below, in accordance with the payment schedule set forth herein. This Note is
being executed and delivered outside the State of Florida.

         1.       PAYMENT TERMS

                  a)   Principal and interest payments under this Note shall be
                       paid to Lender in accordance with the payment schedule
                       set forth on Schedule I attached hereto.

                  b)   If any payment becomes due and payable on a day other
                       than a Business Day, the due date thereof shall be
                       extended to the next succeeding Business Day, and
                       interest shall be payable during the extension at the
                       applicable rate. For purposes of this Note, "Business
                       Day" shall mean any day that is not a Saturday, Sunday or
                       other day on which the commercial banking institutions in
                       the State of New York are authorized or obligated by law
                       or executive order to be closed.

         2.       INTEREST RATE

                  a)   The interest rate for this Note shall be an interest rate
                       equal to thirteen percent (13.00%) per annum.

                  b)   Interest and any fees hereunder shall be computed on the
                       basis of a year comprised of 365 days.

                                                                               1

                  c)   Borrower hereby agrees that upon occurrence and during
                       continuance of an event of default, Lender shall be
                       entitled to receive and Borrower shall pay interest on
                       the entire unpaid principal sum at a rate equal or lesser
                       of (i) eighteen percent (18%) per annum, or (ii) the
                       maximum interest rate which Borrower may by law pay (the
                       "Default Rate"). The Default Rate shall be computed from
                       the occurrence of the event of default until the earlier
                       of the date upon which the event of default is cured or
                       the date upon which the defaulted is paid in full.
                       Interest calculated at the Default Rate shall be added to
                       the principal due under the Note and shall be deemed
                       secured by collateral. This paragraph shall not be
                       construed as an agreement or privilege to extend the date
                       of any payment, nor as a waiver of any other right or
                       remedy accruing to Lender by reason of the occurrence of
                       any event of default.

                  d)   Notwithstanding anything contained herein to the
                       contrary, in no event shall any interest rate provided
                       herein exceed the maximum rate of interest allowed by the
                       applicable law, as amended from time to time. Lender does
                       not intend to charge any amount of interest or other fees
                       or charges in the nature of interest that exceeds the
                       maximum amount allowed by applicable law. If any payment
                       of interest or in the nature of interest would cause the
                       forgoing interest rate limitation to exceed, then such
                       excess payment shall be credited as a payment of
                       principal, unless Borrower notifies Lender in writing
                       that the excess payment must be returned to Borrower,
                       together with interest as the rate specified under New
                       York law.

         3.       PREPAYMENTS

                  a)   Borrower shall be entitled to prepay this Note in whole
                       or in part, at any time, without premium or penalty.

                  b)   Any prepayment of this Note (whether optional or
                       required, but not including any payment after default or
                       acceleration) shall be applied first to principal and
                       then to interest and lawful charges, unless otherwise
                       specified by Borrower. In the event of a prepayment after
                       default or acceleration, any prepayment of this Note
                       shall be applied first to interest accrued on the
                       principal amount prepaid and other lawful charges, and
                       then to principal. Borrower, shall, at the time of making
                       payments of this Note, specify to Lender the amount of
                       this Note to be prepaid.

         4.       SECURITY

                  a)   This Note is secured by Borrower's accounts receivable
                       set forth on Schedule A attached hereto ( the "Accounts
                       Receivable") and

                                                                               2
<PAGE>

                       Borrower hereby grants Lender a security interest in all
                       of such Accounts Receivable.

                  b)   In order to perfect a security interest in the Accounts
                       Receivable, Borrower agrees to execute and deliver to the
                       Lender any and all documents which are, in the opinion of
                       Lender or its counsel, necessary so as to perfect the
                       said security interests including, but not limited to,
                       appropriate UCC-1 financing statements to be filed with
                       the Secretary of State of New York and with the
                       appropriate filing officers in all such jurisdictions
                       where any of the Accounts Receivable may be located.
                       Borrower does hereby appoint Lender as its
                       attorney-in-fact, with full power of substitution, to
                       prepare, execute and file UCC financing statements ,
                       amendments, releases, continuations, assignments and
                       other perfection instruments as Lender deems reasonably
                       necessary or appropriate to protect Lender's interest in
                       the products. Borrower hereby authorizes the Lender to
                       execute and file at any time any financing statements,
                       continuation statements, or amendments thereto, without
                       signatures of Borrower thereon, which the Lender deems
                       reasonably necessary to protect, perfect, continue or
                       maintain the security interests and liens granted to the
                       Lender.

         5.       DEFAULT

                  a)   If an event of default as defined below, occurs and such
                       event of default continues after the expiration of any
                       applicable notice and grace periods, then the whole
                       unpaid principal sum due under this Note, all interest,
                       default interest, late charges and all other monies
                       agreed or provided to be paid by Borrower under this Note
                       shall without notice become immediately due and payable.

                  b)   Unless payments are made in the amount and as required
                       hereunder, remittances in payments of full or any part of
                       the payments due under this Note shall not, regardless of
                       any receipt or credit issued therefore, constitute
                       payment until the required amount is actually received by
                       Lender in funds immediately available as specified herein
                       and shall be made and accepted subject to the condition
                       that any check or draft may be handled for collection in
                       accordance with the practice of the collecting bank or
                       banks. Acceptance by Lender or any payment in an amount
                       then due shall be deemed an acceptance on account only
                       and the failure to pay the entire amount by the tenth
                       (10th) day after the payment due date shall be an event
                       of default.

                  c)   It shall be an event of default under this Note if: (i)
                       Borrower fails to make payment of principal, interest, or
                       other amount as it comes due on any indebtedness owed
                       Lender hereunder, or fails to make any

                                                                               3

                       other payment to Lender as contemplated hereunder either
                       by the terms hereof or otherwise; (ii) any liquidation or

                       which is not vacated, discarded, stayed, bonded or
                       dismissed within sixty (60) days of its commencement, or
                       the entry of an order for relief under any existing or
                       future law of any jurisdiction, domestic or foreign,
                       state or federal, relating to bankruptcy, insolvency,
                       reorganization or relief of debtors, or any other action
                       of Borrower indicating its consent to, approval of or
                       acquiescence in, any such petition, case, proceeding, or

                       its inability to pay its debts as they mature; (iii) any
                       order is entered in any proceedings against Borrower
                       decreeing the dissolution or split-up of Borrower, and
                       such order remains in effect for more than sixty (60)

                       Borrower or its offices, directors or shareholders,
                       leading to, or resulting in, the termination,
                       invalidation (partial or total) , revocation, suspension,
                       interruption, or unenforceability or its existence, or

                       otherwise) to any person of all or a substantial par of
                       its property;

                       Then (i) upon the occurrence of any event of default

                       demand, protest, or other requirement of any kind, all of
                       which are expressly waived by Borrower; and (ii) upon the
                       occurrence and during the continuance of any other event
                       of default Lender may take one or more of the following
                       actions: )a) declare all or any portion of the Note to
                       be, and the same shall forthwith become, immediately due
                       and payable, without presentment, demand, protest, or
                       other requirement of any kind, all of which are expressly
                       waived by Borrower. Lender may immediately proceed to do
                       all other things provided by law to enforce the rights of
                       Lender and to collect all amounts owing to Lender by
                       Borrower. Without limiting foregoing in any way, upon any
                       event of default, Lender shall be entitled to the
                       appointment of a receiver to take charge of the

                       conferred upon Lender by this Note shall be exclusive of
                       any other right, power, or remedy referred to therein or
                       now or hereafter available at law or in equity.

         6.       TRANSFER

                       Lender may assign or transfer this Note and upon such
                       assignment or transfer, Borrower hereby waives notice or
                       any such assignment or transfer and Lender may deliver,

                       with all the rights herein or under applicable law given
                       to Lender with respect thereto, and Lender shall
                       therefore be relieved and fully discharged from any
                       liability or responsibility under this Note.

Demand Note may not be litigated in or by such courts.

                  To the extent  permitted by  applicable  law, the  undersigned
agrees that it shall not seek and hereby  waives the right to seek any review of
