2.   Subject to the terms and conditions of this Revolving Credit Loan
     Agreement, the Credit shall be available to the Borrower in whole or in
     part from time to time, provided that the Lender shall have no obligation
     to make any loan to the Borrower under the Credit after the Repayment Date.
     Except as provided in clause (iii) below, each borrowing under the Credit
     shall be made in whole multiples of U.S.$ 100,000.  Loans shall be effected
     at the principal office of the lender at such times before the Repayment
     Date as the Borrower may request by three (3) Business Days' notice to the
     Lender.  During the term of the Credit, the Borrower may borrow, prepay and
     reborrow in accordance with the provisions of this Revolving Credit Loan
     Agreement.

     (i)    Loans under the Credit shall be evidenced by a promissory note in
            the form of Annex A attached hereto (the "Credit Note"), payable to
            the order of the Lender, duly executed on behalf of the Borrower,
            dated the date of the first borrowing under the Credit. The
            principal on the Credit Note shall be payable on or before the
            Repayment Date and shall bear interest (computed on the basis of a
            365-day year) from the Repayment Date on the unpaid principal amount
            thereof at the Interest Rate, payable on the Interest Payment Dates,
            commencing with the first of such dates next succeeding the date of
            the Credit Note and continuing until the later of payment in full of
            the Credit Note or the Repayment Date.

     (ii)   On three (3) Business Days' written notice (via facsimile or
            registered mail) to Lender, the Borrower may at its option prepay
            the Credit Note in whole at any time, or in part, from time to time,
            without payment penalty or premium but with all accrued and unpaid
            interest. Each partial prepayment shall be made in integrals of
            U.S.$ 100,000.

     (iii)  Amounts due from the Borrower to the Lender or due from the Lender
            to the Borrower in respect of Net Retention Adjustments pursuant to
            Section 2.3 of the General Assignment and Assumption Agreement
            between the Lender and the Borrower, in whatever integral, shall be
            treated as loans or prepayments hereunder, respectively, and
            notation thereof shall be made on the Credit Note in accordance with
            clause (iv) below.

     (iv)   The Lender shall make notation on the Credit Note of the amount of
            each loan made under the Credit, each payment or prepayment, the
            date thereof, the balance remaining due on the Credit Note as the
            result of each loan or payment and the other information specified
            on Credit Note.

3.   If the Borrower shall not pay on the due date any amount payable hereunder,
     the Borrower shall pay to the Lender, without prejudice to any other rights
     of the Lender hereunder or at law, default interest at the per annum rate
     specified under Interest Rate in Section 1 above.

4.   The Borrower's obligation to make any and all payments hereunder shall be
     absolute and unconditional and shall not be affected by any event or
     circumstance, including without limitation (i) any set-off, counterclaim,
     defense or other right which the Borrower may have against the Lender or
     any other person for any reason whatsoever, or (ii) any other event or
     circumstance whatsoever, whether or not similar to any of the foregoing.
     The Borrower shall make all payments hereunder in the currency in which
     they are expressed to

                                     --2--
<PAGE>

     be due by 11:00 a.m. on the due date in the location of payment to the
     Lender's account and bank specified by the Lender in advance, in full, and
     free and clear of all taxes and other withholdings or deductions of
     whatsoever nature.

5.   If the Borrower shall (i) make any default hereunder which is not remedied
     within 21 days or (ii) admit in writing its inability to pay its debts
     generally as they fall due, or (iii) apply for, or consent to, the
     appointment of, or the taking of possession by, a receiver, trustee,
     liquidator or the like of itself, or of all or a substantial part of its
     assets or (iv) be adjudicated or declared bankrupt or insolvent by any
     competent authority or (v) submit or consent to any proceedings for any
     such action, adjudication or (vi) submit or consent to any proceedings for
     any such action, adjudication or declaration, then, the Lender may,
     notwithstanding any delay or previous waiver of the right to do so, by
     notice in writing to the Borrower require the Borrower forthwith to prepay
     the balance of the loan outstanding hereunder together with accrued but
     unpaid interest and any other amounts owing hereunder, whereupon the same
     shall become immediately due and payable on such date.

6.   The Borrower shall not create or permit to exist any charge, mortgage, lien
     or encumbrance whatsoever on any of its assets for money borrowed unless
     the Borrower shall first have granted to the Lender security for its
     obligations hereunder ranking at least pari passu therewith and (save for
     debts preferred by law) the obligations hereunder shall rank at least pari
     passu with all other liabilities of the Borrower.

7.   The Borrower shall on demand indemnify the Lender, and reimburse the Lender
     upon demand, for all costs, losses, expenses (including reasonable legal
     expenses) and liabilities which the Lender may sustain or incur as a
     consequence of the occurrence and continuance of any default hereunder or
     any prepayment of any loan under the Credit pursuant to Clause 4.

8.   The Borrower may not assign or transfer any of its rights or obligations
     under this Agreement without the prior written consent of the Lender.

9.   This Agreement shall in all respects be governed by, and construed in
     accordance with, the laws of the Commonwealth of Massachusetts as applied
     to transactions between Massachusetts residents taking place entirely
     within Massachusetts.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
by their respective duly authorized officers all as of the date first above
written.

as follows:

     (a) The execution and delivery of this Third Amendment (i) is within the
corporate authority of the Borrower, (ii) has been duly authorized by all
necessary corporate proceedings on the part of the Borrower, (iii) does not
conflict with or result in any material breach or contravention of any provision

obligations of the Borrower party thereto enforceable against the Borrower in
accordance with the respective terms and provisions hereof and thereof, except
as enforceability is limited by bankruptcy, insolvency, reorganization,
moratorium or other laws relating to or affecting generally the enforcement of
creditors rights and except to the extent that availability of the remedy of
specific performance or injunctive relief is subject to the discretion of the
court before which any proceeding therefor may be brought.

     (d) As of the Third Amendment Effective Date, no Default or Event of
Default or condition which would result in a Default or Event of Default has
occurred and is continuing (except that which would have occurred but for the
