All capitalized terms used in this Promissory Note shall have the meaning

         This Promissory Note shall bear interest at a rate of ten percent (10%)

(each, an "Event of Default") shall terminate any obligation on the part of the

become due and payable without any action by or on behalf of the Lender), and
the Lender may exercise any and all rights and remedies for the collection of
any amounts outstanding hereunder and take whatever action it deems necessary to

<PAGE>   2

secure itself all without notice of default, presentment, or demand for payment,
protest, or notice of nonpayment or dishonor, or other notices or demands of any
kind or character:

         (a) Failure of the Borrower to pay within ten (10) days of the date
when due, whether by acceleration or otherwise, any of the Indebtedness in
accordance with this Promissory Note.

         (b) Any representation or warranty set forth in the Stock Acquisition
Agreement, this Promissory Note or any Advance Request (as defined in Section
3.1.4 herein), or in connection with any transaction contemplated by any such
document, shall prove in any material respect to have been false or misleading
when made by the Borrower.

         (c) Any default by the Borrower in the performance or compliance with
the covenants, promises, conditions or provisions of this Promissory Note.

         (d) The failure to pay when due, or failure to perform or observe any
other obligation or condition with respect to any of the following obligations
to any Person, beyond any period of grace under the instrument creating such
obligation: (i) any indebtedness for borrowed money or for the deferred purchase
price of property in excess of $25,000.00, (ii) any obligations under leases
which have or should have been characterized as capitalized leases, as
determined in accordance with GAAP, or (iii) any contingent liabilities, such as
guaranties, for the obligations of others relating to indebtedness for borrowed
money or for the deferred purchase price of property or services or relating to
obligations under leases which have or should have been characterized as
capitalized leases, as determined in accordance with GAAP.

         (e) The Borrower applies for or consents to the appointment of a
trustee or receiver for any part of its respective properties; any bankruptcy,
reorganization, debt arrangement, dissolution, or liquidation proceeding is
commenced or consented to by the Borrower, or any application for appointment of
a receiver or a trustee, or any proceeding for bankruptcy, reorganization, debt
management, or liquidation is filed for or commenced against the Borrower, and
is not withdrawn or dismissed within sixty (60) days thereafter; PROVIDED,
however, that within said sixty (60) day period the Lender shall have no
obligation to disburse the Loan Proceeds.

         (f) Failure of the Borrower to comply with any other provision of this
Promissory Note or the Stock Purchase Agreement not constituting an Event of
Default under any of the preceding provisions of this Section 1.1, and such
failure continues for thirty (30) days after notice to the Borrower from the
Lender.

         (g) Any lien for labor, services, materials, or otherwise is filed
against any property of the Borrower or any interest of the Borrower or the
Lender therein and is not removed within thirty (30) days thereafter; PROVIDED,
HOWEVER, the Borrower will not be deemed to be in default under this
subparagraph if and so long as the Borrower: (i) contests in good faith the
validity or amount of any asserted lien and diligently prosecutes or defends an
action appropriate to obtain a binding determination of the disputed matter and
such contest shall have the effect of preventing the sale or forfeiture of any

                                      -2-
<PAGE>   3

property of the Borrower or any interest of the Borrower or the Lender therein;
and (ii) provides the Lender with such security as the Lender may require to
protect the Lender against all loss, damage, and expense, including attorneys'
fees, which it might incur if the asserted lien is determined to be valid.

         (h) Without having first obtained the written consent of the Lender,
the Borrower transfers, sells, conveys, assigns, or further encumbers all or any
portion of the Borrower's interest in any property, except as in the ordinary
course of Borrower's business.

         (i) Upon the commencement of any legal or governmental actions,
proceedings or investigations to which the Borrower is a party or to which any
property of the Borrower is subject and which could result in any material
adverse change in the business, operations, properties or financial condition or
performance of the Borrower, unless: (i) dismissed with thirty (30) days of
commencement, or (ii) if and so long as Borrower contests in good faith the
validity or amount of any asserted lien and diligently prosecutes or defends an
action appropriate to obtain a binding determination of the disputed matter and
such contest shall have the effect of preventing the sale or forfeiture of any
property of the Borrower or any interest of the Borrower or the Lender therein;
and provides the Lender with such security as the Lender may require to protect
the Lender against all loss, damage, and expense, including attorney's fees,
which Lender might incur if the asserted lien is determined to be valid.

         1.2 NO ADVANCES. The Lender shall have no obligation to disburse the
Loan Proceeds if an Event of Default shall occur and be continuing.

         1.3 BORROWER'S BOARD OF DIRECTORS. The Lender shall have the right to
appoint a majority of the members of the Borrower's board of directors due to
the occurrence of an Event of Default under Subsection (a) of Section 1.1 of
this Article 1 if such default continues for thirty (30) days after notice of
such default is given to Borrower.

         1.4 RIGHTS AND REMEDIES. In addition to the remedies set forth in
Sections 1.1 through 1.3 of this Promissory Note, upon the occurrence of an
Event of Default, and until cured (provided such cure is effected prior to the
Lender giving the Borrower written notice of the election by the Lender to
accelerate all amounts owing under this Promissory Note on account of such Event
of Default), the Lender shall be entitled to exercise all the rights and
remedies provided by any applicable law, including, without limitation, the
Uniform Commercial Code as enacted in the State of New Jersey. Each and every
right or remedy granted to the Lender pursuant to this Promissory Note, or
allowed the Lender by law or equity, shall be cumulative. Failure or delay on
the part of the Lender to exercise any such right or remedy shall not operate as
a waiver thereof. Any single or partial exercise by the Lender of any such right
or remedy shall not preclude any future exercise thereof or the exercise of any
other right or remedy.

                        ARTICLE 2: AFFIRMATIVE COVENANTS

         From and after the date of this Promissory Note and until the
Indebtedness is indefeasibly paid, in full, in cash, and the Lender has no
obligation to make any Advances hereunder, the Borrower agrees that it will
observe and comply with the following covenants for the benefit of the Lender.

         2.1 USE OF LOAN PROCEEDS. The Loan Proceeds made available to Borrower

information regarding Borrower's working capital requirements as Lender may
request while this Promissory Note is outstanding.

         2.2 FUTURE DEBT. Borrower will not issue, incur, create, assume,
guarantee or otherwise become liable for any other indebtedness for borrowed
money unless such other indebtedness is subordinated in right of payment to this
Indebtedness under this Promissory Note.

                        ARTICLE 3: CONDITIONS TO ADVANCES

         3.1 CONDITIONS TO LOAN. The Lender's obligation to make the Loan and to
