Debt shall be applied towards the Liabilities in such order and manner as the
Lender determines in its sole discretion (whether or not any default exists

Liabilities shall be paid to the Creditor.

      12. The subordination effected hereby shall not be affected by any
fraudulent, illegal, or improper act by the Borrower, the Creditor, or any
person liable or obligated to the Lender for or on the Liabilities, nor by any
release, discharge or invalidation, by operation of law or otherwise, of the
Liabilities or by the legal incapacity of the Borrower, the Creditor, or any
other person liable or obligated to the Lender for or on the Liabilities. All
interest and costs of collection with respect to the Liabilities for which the
Borrower has agreed to be liable shall continue to accrue and shall continue to
be Liabilities for purposes of the subordination effected hereby notwithstanding
any stay to the enforcement thereof against the Borrower or disallowance
therefor against the Borrower.

      13. The books and records of the Lender showing the account between the
Lender and the Borrower or the Lender and the Creditor shall be admissible in
any action or proceeding to enforce the within agreement and shall constitute
prima facie evidence and proof of the items contained therein.

      14. In the event (a) the Lender determines that any representation made by
the Borrower or the Creditor to the Lender herein was not true or accurate when
given and/or (b) the Borrower or the Creditor (or both) fails to promptly,
punctually, and faithfully perform or discharge any obligation hereunder or an
event of default occurs under any other instrument, document, or agreement
between the Borrower or the Creditor and the Lender, all Liabilities, and any
and all liabilities, obligations, and indebtedness of the Creditor to the
Lender, whether arising hereunder or under any other document, instrument, or

demand.

expenses incurred by the Lender's attorneys and all costs incurred by the
Lender, including, without limitation, costs associated with travel on behalf of
the Lender, which costs and expenses are directly or indirectly related to the
Lender's efforts to preserve, protect, collect, or enforce any of the

any of the Lender's Rights and Remedies hereunder (whether or not suit is
instituted by or against the Lender).


                                      -3-
<PAGE>

      16. The Creditor will pay on demand all attorneys' fees and out-of-pocket
expenses incurred by the Lender's attorneys and all costs incurred by the
Lender, including, without limitation, costs associated with travel on behalf of
the Lender, which costs and expenses are directly or indirectly related to the
Lender's efforts to preserve, protect, collect, or enforce any of the
obligations of the Creditor and/or any of the Lender's Rights and Remedies
hereunder (whether or not suit is instituted by or against the Lender).

      17. The within Agreement incorporates all discussions and negotiations
amongst and between the Borrower, the Creditor, and the Lender concerning the
subordination effected hereby. No such discussions or negotiations shall limit,
modify, or otherwise affect the provisions hereof. No provisions hereof may be
altered, amended, waived, cancelled, or modified, except by a written instrument
executed, sealed, and acknowledged by a duly authorized officer of the Lender.

      18. The Lender may continue to rely upon the within Agreement and the
subordination effected hereby with respect to all Liabilities which may arise
hereafter. The repayment and satisfaction of all of such Liabilities shall not
terminate the within Agreement and the subordination effected hereby as to
Liabilities which arise thereafter.

      19. The rights, remedies, powers, privileges, and discretions of the
Lender hereunder (hereinafter, the "Lender's Rights and Remedies") shall be
cumulative and not exclusive of any rights or remedies which it would otherwise
have. No delay or omission by the Lender in exercising or enforcing any of the
Lender's Rights and Remedies shall operate as, or constitute, a waiver thereof.
No waiver by the Lender of any of the Lender's Rights and Remedies or of any
default or remedy under any other agreement with the Borrower or the Creditor
shall operate as a waiver of any other default hereunder or thereunder. No
exercise of the Lender's Rights and Remedies and no other agreement or
transaction, of whatever nature, entered into between the Lender and the
Creditor and/or between the Lender and the Borrower at any time shall preclude
any other or further exercise of the Lender's Rights and Remedies. No waiver by
the Lender of any of the Lenders' Rights and Remedies on any one occasion shall
be deemed a continuing waiver. All of the Lender's Rights and Remedies and all
of the Lender's rights, remedies, powers, privileges, and discretions under any
other agreement with the Creditor and/or the Borrower shall be cumulative, and
not alternative or exclusive, and may be exercised by the Lender at such time or
times and in such order of preference as the Lender in its sole discretion may
determine. The Lender may proceed with respect to the Junior Debt and the Junior
Collateral without resort or regard to other collateral or sources of
satisfaction of the Liabilities or the liabilities, obligations and indebtedness
of the Creditor to the Lender.

      20. As used herein, the following terms have the following meanings:

      "Liability" and "Liabilities" shall have the meaning set forth in that
certain Revolving Credit and Term Loan Agreement dated February 28, 2000 by and
between the Borrower and the Lender, as the same may be modified, amended and/or
restated.

      The Lender's books and records shall be prima facie evidence of the
Borrower's Liabilities.

      "Junior Debt" includes all liabilities, obligations, and indebtedness now
or hereafter owed by the Borrower to the Creditor pursuant to that certain
promissory note dated February 28, 2000 in the original principal amount of
Three Hundred Thousand and 00/100 Dollars made payable by the Borrower to the
Creditor.

      21. The within Agreement shall be binding upon the Creditor, the Borrower
and their respective heirs, executors, administrators, representatives,
successors, and assigns, and shall inure to the benefit of the Lender, and the
Lender's successors and assigns. Without limiting the foregoing, any assignee of
the Creditor shall be bound by the terms and conditions of this Agreement, and
such assignee shall, at the Lender's option, execute and deliver to the Lender
such documents as the Lender may reasonably require


                                      -4-
<PAGE>

to confirm such assignee's acknowledgment of the same. However, the failure of
such assignee to execute any such document shall in no way modify or impair the
terms and conditions of this Agreement.

      22. It is intended that this Agreement take effect as a sealed instrument
and be governed by the laws of The Commonwealth of Massachusetts. The Creditor
and the Borrower each submit to the jurisdiction of the courts of said
Commonwealth for all purposes in connection with the within Agreement and their
respective relationships with the Lender.

      23. The Borrower makes the following waiver knowingly, voluntarily, and
intentionally and understands that the Lender, in the establishment and
maintenance of the Lender's relationship with the Borrower, is relying thereon.
THE BORROWER, TO THE EXTENT ENTITLED THERETO, WAIVES ANY PRESENT OR FUTURE RIGHT
OF THE BORROWER, OR OF ANY GUARANTOR OR ENDORSER OF THE BORROWER OR OF ANY OTHER
PERSON LIABLE TO THE LENDER ON ACCOUNT OF OR IN RESPECT TO THE LIABILITIES, TO A
TRIAL BY JURY IN ANY CASE OR CONTROVERSY IN WHICH THE LENDER IS OR BECOMES A
PARTY (WHETHER SUCH CASE OR CONTROVERSY IS INITIATED BY OR AGAINST THE LENDER OR
IN WHICH THE LENDER IS JOINED AS A PARTY LITIGANT), WHICH CASE OR CONTROVERSY
ARISES OUT OF, OR IS IN RESPECT TO, ANY RELATIONSHIP AMONGST OR BETWEEN THE
BORROWER, ANY SUCH PERSON, AND THE LENDER.

      The undersigned certify that the undersigned read this Agreement prior to
its execution.
