In consideration of the mutual promises contained herein and in the other documents referred to below, and for other good and valuable consideration, receipt and sufficiency of which are hereby acknowledged, the Borrower and the Bank agree as follows: I. AMOUNTS AND TERMS 1.1 REFERENCES TO DOCUMENTS. Reference is made to (i) that certain $ 1,000,000 face principal amount promissory note (the "Term Note") of even date herewith made by the Borrower and payable to the order of the Bank, and (ii) that certain Security Agreement of even date herewith from the Borrower to the Bank (the "Security Agreement"). 1.2. The BORROWING; TERM NOTE. Subject to the terms and conditions hereinafter set forth, the Bank will make one or more loans (the "Term Loans") to the Borrower, as the Borrower may request, on any Business Day prior to the first to occur of (i) December 31, 1997 or (ii) the earlier termination of the within-described term loan facility pursuant to (section) 5.2 or (section)6.7. A Term Loan shall be made, not more than once per calendar quarter (except that more than one Term Loan may be made in any calendar quarter provided that each additional Term Loan in any one calendar quarter is in an amount of at least $250,000), in order to finance costs of Qualifying Equipment acquired by the Borrower within the 90 days preceding the request for such Term Loan and/or Qualifying Software/Engineering Costs incurred by the Borrower within the 90 days preceding such request, each such Term Loan to be in such amount as may be requested by the Borrower; provided that (i) no Term Loan will be made after December 31, 1997; (ii) the aggregate original principal amounts of all Term Loans will not exceed $1,000,000; and (iii) no Term Loan will be in an amount in excess of the sum of (1) 90% of the invoiced actual costs of the property constituting the items of Qualifying Equipment with respect to which such Term Loan is made (excluding taxes, shipping, software, installation charges, training fees and other "soft costs"), PLUS (2) 90% of the Qualifying Software/Engineering Costs with respect to which such Term Loan is made (provided that the Qualifying Software/Engineering Costs which can be used to support Term Loans may not exceed $300,000 in the aggregate). Prior to the making of 2 -2- each Term Loan, and as a precondition thereto, the Borrower will provide the Bank with: (i) invoices supporting the costs of the relevant Qualifying Equipment (and, if relevant, invoices supporting the Qualifying Software/Engineering Costs); (ii) such evidence as the Bank may reasonably require showing that the Qualifying Equipment (and any software the purchase of which is included within Qualifying Software/Engineering Costs) has been delivered to and installed at the Borrower's Marlborough, MA premises, has become fully operational, has been paid for by the Borrower and is owned by the Borrower free of all liens and interests of any other Person (other than the security interest of the Bank pursuant to the Security Agreement); (iii) supplements to the Security Agreement and related Uniform Commercial Code financing statements reflecting the relevant Qualifying Equipment with respect to which such Term Loan is being made and partial releases from Silicon Valley Bank relating to such Qualifying Equipment (all of the foregoing to be in form and substance satisfactory to the Bank); and (iv) evidence satisfactory to the Bank that the Qualifying Equipment is fully insured against casualty loss, with insurance naming the Bank as secured party and first loss payee. The Term Loans will be evidenced by the Term Note. Interest on the Term Loans shall be payable at the times and at the rate provided for in the Term Note. Overdue principal of any Term Loan and, to the extent permitted by law, overdue interest shall bear interest at a fluctuating rate per annum which at all times shall be equal to the sum of (i) two (2%) percent per annum plus (ii) the per annum rate otherwise payable under the Term Note (but in no event in excess of the maximum rate from time to time permitted by then applicable law), compounded monthly and payable on demand. The Borrower hereby irrevocably authorizes the Bank to make or cause to be made, on a schedule attached to the Term Note or on the books of the Bank, at or following the time of making each Term Loan and of receiving any payment of principal, an appropriate notation reflecting such transaction and the then aggregate unpaid principal balance of the Term Loans. The amount so noted shall constitute presumptive evidence as to the amount owed by the Borrower with respect to principal of the Term Loans. Failure of the Bank to make any such notation shall not, however, affect any obligation of the Borrower or any right of the Bank hereunder or under the Term Note. 1.3. PRINCIPAL REPAYMENT OF TERM LOANS. The Borrower shall repay principal of the Term Loans in 36 equal consecutive monthly installments, commencing on January 30, 1998 and continuing on the last Business Day of each month thereafter. Each such monthly installment of principal shall be in an amount equal to 1/36th of the aggregate principal amount of the Term Loans outstanding at the close of business on December 31, 1997. In any event, the then outstanding principal balance of the Term Loans and all interest then accrued but unpaid thereon shall be due and payable in full on the December 29, 2000. The Borrower may prepay, at any time or from time to time, without premium or penalty, the whole or any portion of any Term Loan; provided that each such principal prepayment shall be accompanied by payment of all interest under the Term Note accrued but unpaid to the date of payment. Any partial prepayment of principal of the Term Loans will be applied to installments of principal of the Term Loans thereafter coming due in inverse order of normal maturity. Amounts repaid or prepaid with respect to the Term Loans are not available for reborrowing. 1.4. ADVANCES AND PAYMENTS. The proceeds of all Term Loans shall be credited by the Bank to a general deposit account maintained by the Borrower with the Bank. The proceeds of 3 -3- each Term Loan will be used by the Borrower solely for acquisition of Qualifying Equipment and/or for payment of Qualifying Software/Engineering Costs. The Bank may charge any general deposit account of the Borrower at the Bank with the amount of all payments of interest, principal and other sums due, from time to time, under this letter agreement and/or the Term Note; and will thereafter notify the Borrower of the amount so charged. The failure of the Bank so to charge any account or to give any such notice shall not affect the obligation of the Borrower to pay interest, principal or other sums as provided herein or in the Term Note. Whenever any payment to be made to the Bank hereunder or under the Term Note shall be stated to be due on a day which is not a Business Day, such payment may be made on the next succeeding Business Day, and interest payable on each such date shall include the amount thereof which shall accrue during the period of such extension of time. All payments by the Borrower hereunder and/or in respect of the Term Note shall be made net of any impositions or taxes and without deduction, set-off or counterclaim, notwithstanding any claim which the Borrower may now or at any time hereafter have against the Bank. All payments of interest, principal and any other sum payable hereunder and/or under the Term Note shall be made to the Bank, in immediately available funds, at its office at 75 State Street, Boston, MA 02109 or to such other address as the Bank may from time to time direct. All payments received by the Bank after 2:00 p.m. on any day shall be deemed received as of the next succeeding Business Day. All monies received by the Bank shall be applied first to fees, charges, costs and expenses payable to the Bank under this letter agreement, the Term Note and/or any of the other Loan Documents, next to interest then accrued on account of any Term Loans and only thereafter to principal of the Term Loans. All interest and fees payable hereunder and/or under the Term Note shall be calculated on the basis of a 360-day year for the actual number of days elapsed. 1.5. CONDITIONS TO ADVANCE. Prior to the making of the initial Term Loan, the Borrower shall deliver to the Bank duly executed copies of this letter agreement, the Security Agreement, the Term Note and the documents and other items listed on the Closing Agenda delivered herewith by the Bank to the Borrower, all of which, as well as all legal matters incident to the transactions contemplated hereby, shall be satisfactory in form and substance to the Bank and its counsel.

(d) No material adverse change shall have occurred in the financial condition of the Borrower from that disclosed in the financial statements then most recently furnished to the Bank. Each request by the Borrower for any Term Loan, and each acceptance by the Borrower of the proceeds of any Term Loan, will be deemed a representation and warranty by the Borrower that at the date of such Term Loan and after giving effect thereto all of the conditions set forth in the foregoing clauses (a)-(d) of this sec.1.5 will be satisfied.
