Exhibit 10(a) ABIOMED, INC. 22 Cherry Hill Drive Danvers, ma 01923 October 14, 1999 Fleet National Bank One Federal Street Boston, MA 02110 Gentlemen: This letter agreement will set forth certain understandings between ABIOMED, Inc., a Delaware corporation (the "Borrower") and Fleet National Bank (the "Bank") with respect to Demand Loans and Term Loans (each as hereinafter defined) which may be made by the Bank to the Borrower and with respect to letters of credit which may hereafter be issued by the Bank for the account of the Borrower. 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. REFERENCE TO DOCUMENTS. Reference is made to (i) that certain $3,000,000 face principal amount demand promissory note (the "Demand Note") of even date herewith made by the Borrower and payable to the order of the Bank, (ii) that certain $250,000 face principal amount term promissory note (the "Tranche A Term Note") of even date herewith made by the Borrower and payable to the order of the Bank, (iii) that certain $400,000 face principal amount term promissory note (the "Tranche B Term Note") of even date herewith made by the Borrower and payable to the order of the Bank, (iv) that certain $550,000 face principal amount term note (the "Tranche C Term Note") made by the Borrower and payable to the order of the Bank, and (v) that certain Security Agreement (Equipment) of even date herewith from the Borrower to the Bank (the "Security Agreement"). This letter agreement and the Demand Note supersede and replace in its entirety that certain Demand Line of Credit Promissory Note dated October 21, 1998 made by the Borrower and payable to the order of the Bank (the "Prior Note"). From and after the date hereof the Bank shall not be deemed to have any obligations or commitments under or in respect of the loan facility evidenced by the Prior Note. All loans outstanding under the Prior Note at the date of execution and delivery of this letter agreement shall be deemed refunded and replaced by Demand Loans hereunder. 1.2. DEMAND LOANS; DEMAND NOTE. Subject to the terms and conditions hereinafter set forth, the Bank may, in the Bank's discretion, make loans ("Demand Loans") to the Borrower, in such amounts as the Borrower may request, on any Business Day prior to the first to occur of (i) the Expiration Date, or (ii) the date of any demand for payment under the Demand Note, or (iii) the earlier termination of the within-described financing arrangements for Demand Loans pursuant to Section 5.2 or Section 6.6; provided, however, that the aggregate principal amount of the Demand Loans outstanding shall at no time exceed the Maximum Demand Loan Amount (hereinafter defined) as then in effect. Within such limit, and subject to the terms and conditions hereof, the Borrower may obtain Demand Loans, repay Demand Loans and obtain Demand Loans again on one or more occasions. The Demand Loans shall be evidenced by the Demand Note. The Borrower hereby irrevocably authorizes the Bank to make or cause to be made, on a schedule attached to the Demand Note or on the books of the Bank, at or following the time of making each Demand Loan and of receiving any payment of principal of a Demand Loan, an appropriate notation reflecting such transaction and the then aggregate unpaid principal balance of the Demand Loans. The amount so noted shall constitute presumptive evidence as to the amount owed by the Borrower with respect to principal of the Demand 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 Demand Note. 1.3. REPAYMENT; RENEWAL OF DEMAND LOAN FACILITY. The Borrower shall repay in full all Demand Loans and all interest thereon upon the first to occur of: (i) the Expiration Date, or (ii) the date of any demand for payment (which demand may be made by the Bank at any time in the Bank's discretion, whether or not any Default or Event of Default has occurred), or (iii) an acceleration under Section 5.2(a) following an Event of Default. The Borrower may repay at any time, without penalty or premium, the whole or any portion of any Demand Loan. The Bank may, at its sole discretion, renew the financing arrangements described in Section 1.2 by extending the Expiration Date in a writing signed by the Bank and accepted by the Borrower. Neither the inclusion in this letter agreement or elsewhere of covenants relating to periods of time after the Expiration Date, nor any other provision hereof, nor any action (except a written extension pursuant to the immediately preceding sentence), non-action or course of dealing on the part of the Bank will be deemed an extension of, or agreement on the part of the Bank to extend, the Expiration Date. 1.4. TERM LOANS; TERM NOTES. In addition to the foregoing, subject to the terms and conditions of this letter agreement, the Bank will make one or more term loans (the "Term Loans") to the Borrower. The Term Loans are available as follows: (1) At the Borrower's request, and subject to the terms and conditions of this letter agreement, the Bank will make one or more Term Loans ("Tranche A Term Loans") to the Borrower in an aggregate original principal amount not to exceed $250,000. Such Tranche A Term Loans may be made on any Business Day prior to the first to occur of (i) the close of business on November 30, 1999 or (ii) the earlier termination of the Term Loan facilities pursuant to Section 5.2 or Section 6.6. (2) In addition, at the Borrower's request, and subject to the terms and conditions of this letter agreement, the Bank will make one or more Term Loans ("Tranche B Term Loans") to the Borrower in an aggregate original principal amount not to exceed $400,000. Such Tranche B Term Loans may be made on any Business Day prior to the first to occur of (i) the close of business on January 31, 2000 or (ii) the earlier termination of the Term Loan facilities pursuant to Section 5.2 or Section 6.6. (3) In addition, at the Borrower's request, and subject to the terms and conditions of this letter agreement, the Bank will make one or more Term Loans ("Tranche C Term Loans") to the Borrower in an aggregate original principal amount not to exceed $550,000. Such Tranche C Term Loans may be made on any Business Day prior to the first to occur of (i) the close of business on March 31, 2000 or (ii) 2 the earlier termination of the Term Loan facilities pursuant to ss.5.2 or ss.6.6. Thus, the maximum aggregate original principal amounts of the Term Loans available to the Borrower will be $1,200,000. At the time of each such request, the Borrower will indicate whether the Borrower requests a Tranche A Term Loan, a Tranche B Term Loan or a Tranche C Term Loan and the amount of the Term Loan of such Tranche being requested. A Term Loan of any Tranche (or contemporaneous Term Loans of two or more Tranches) shall be made, no more than once per month (unless the Bank shall consent to more frequent Term Loans), in order to finance costs of Qualifying Equipment acquired by the Borrower within the 60 days preceding the request for such a Term Loan and/or to finance the costs of Qualifying Leasehold Improvements incurred by the Borrower during the 60 days preceding such request. Each such Term Loan shall be in such amount as may be requested by the Borrower; provided that (i) no Term Loan of any Tranche will be made after the expiry date for such Tranche set forth above in this ss.1.4; (ii) the aggregate original principal amounts of the Term Loans of each Tranche shall not exceed the amount set forth above in this ss.1.4 as the maximum amount for such Tranche nor will the aggregate original principal amounts of all Term Loans exceed $1,200,000; (iii) no Term Loan will be in an amount more than 90% of the invoiced actual costs of the tangible property constituting the items of Qualifying Equipment and/or Qualifying Leasehold Improvements with respect to which such Term Loan is made (excluding taxes, shipping, software, installation charges, training fees and other "soft costs"); except that the Borrower may in its sole discretion elect to deposit with the Bank and pledge to the Bank cash equal to 10% of the original principal amount of any Term Loan; and if it so elects and pursuant to such election deposits with the Bank and pledges to the Bank (by instruments satisfactory in form and substance to the Bank) cash equal to 10% of the original principal amount of any Term Loan, then the amount of such Term Loan (including the amount so pledged) will be 100% of said invoiced actual costs; and (iv) the aggregate principal amount of all Term Loans made with respect to Qualifying Leasehold Improvements will not exceed the lesser of (A) $400,000 or (B) 30% of the total principal amounts of all Term Loans made at or prior to the date of the making of any such Term Loan for Leasehold Improvements. Prior to the making of 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/or the costs of the relevant Qualifying Leasehold Improvements, as the case may be; (ii) such evidence as the Bank may reasonably require showing that each item of Qualifying Equipment has been delivered to and installed at the Borrower's Danvers, MA premises, has been accepted by the Borrower, 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) such evidence as the Bank may reasonably require showing that each item of Qualifying Leasehold Improvements has been constructed at or installed at the Borrower's Danvers, MA premises, 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), except that the Bank acknowledges that certain Qualifying Leasehold Improvements may be so built into the real estate at the Borrower's Danvers, MA premises that the Borrower's landlord will, upon termination of the Borrower's lease, have rights in such Qualifying Leasehold Improvements; (iv) Uniform Commercial Code financing statements and appropriate supplements to the Security Agreement reflecting the relevant Qualifying Equipment and/or Qualifying Leasehold Improvements with respect to which such Term Loan is being made; and (v) evidence satisfactory to the Bank that 3 the Qualifying Equipment and the Qualifying Leasehold Improvements are fully insured against casualty loss, with insurance naming the Bank as secured party and first loss payee. The Tranche A Term Loans will be evidenced by the Tranche A Term Note. The Tranche B Term Loans will be evidenced by the Tranche B Term Note. The Tranche C Term Loans will be evidenced by the Tranche C Term Note. The Borrower hereby irrevocably authorizes the Bank to make or cause to be made, on a schedule attached to the appropriate 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 of any Term Loan, an appropriate notation reflecting such transaction and the then aggregate unpaid principal balance of the Term Loans of that Tranche to which such Term Note relates. The amount so noted on each Term Note shall constitute presumptive evidence as to the amount owed by the Borrower with respect to principal of the Term Loans of that Tranche to which such Term Note relates. 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 any Term Note. 1.5. PRINCIPAL REPAYMENT OF TERM LOANS. The Borrower shall repay principal of the Tranche A Term Loans in 45 equal consecutive monthly installments (each in an amount equal to 1/46th of the aggregate principal amount of the Tranche A Term Loans outstanding at the close of business on November 30, 1999), such monthly installments to commence on December 1, 1999 and to continue on the first day of each month thereafter through and including August 1, 2003, PLUS a 46th and final installment due and payable on September 1, 2003 in an amount equal to the entire then outstanding principal balance of the Tranche A Term Loans and all interest then accrued but unpaid thereon to the date of payment. The Borrower may prepay, at any time or from time to time, without premium or penalty, the whole or any portion of the Tranche A Term Loans to the extent that same are Floating Rate Term Loans; provided that each such principal prepayment shall be accompanied by payment of all interest on the amount so prepaid accrued under the Tranche A Term Note but unpaid to the date of payment. The Borrower may prepay the whole or any portion of any Tranche A Term Loan which is a LIBOR Term Loan; provided that (i) the Borrower gives the Bank not less than two (2) Business Days' prior written notice of its intent so to prepay, (ii) the Borrower pays all interest on each such Tranche A Term Loan which is a LIBOR Term Loan (or portion thereof) so prepaid accrued to the date of such prepayment, (iii) any voluntary prepayment with respect to a Tranche A Term Loan which is a LIBOR Term Loan must be in an integral multiple of $100,000 (provided that, in any event, no Tranche A Loan which is a LIBOR Term Loan will remain outstanding in a principal amount of less than $100,000), and (iv) if the Borrower for any reason makes any prepayment of a Tranche A Term Loan which is a LIBOR Term Loan prior to the last day of the Interest Period applicable thereto, the Borrower shall forthwith pay all amounts owing to the Bank pursuant to the provisions of ss.1.9 with respect to such LIBOR Term Loan. Any partial prepayment of principal of the Tranche A Term Loans will be applied to installments of principal of the Tranche A Term Loans thereafter coming due in inverse order of normal maturity. Amounts repaid or prepaid with respect to the Tranche A Term Loans are not available for reborrowing. The Borrower shall repay principal of the Tranche B Term Loans in 43 equal consecutive monthly installments (each in an amount equal to 1/44th of the aggregate principal amount of the 4 Tranche B Term Loans outstanding on at the close of business on January 31, 2000), such monthly installments to commence on February 1, 2000 and to continue on the first day of each month thereafter through and including August 1, 2003, PLUS a 44th and final installment due and payable on September 1, 2003 in an amount equal to the entire then outstanding principal balance of the Tranche B Term Loans and all interest then accrued but unpaid thereon to the date of payment.

The Borrower may prepay the whole or any portion of any Tranche B Term Loan which is a LIBOR Term Loan; provided that (i) the Borrower gives the Bank not less than two (2) Business Days' prior written notice of its intent so to prepay, (ii) the Borrower pays all interest on each such Tranche B Term Loan which is a LIBOR Term Loan (or portion thereof) so prepaid accrued to the date of such prepayment, (iii) any voluntary prepayment with respect to a Tranche B Term Loan which is a LIBOR Term Loan must be in an integral multiple of $100,000 (provided that, in any event, no Tranche B Loan which is a LIBOR Term Loan will remain outstanding in a principal amount of less than $100,000), and (iv) if the Borrower for any reason makes any prepayment of a Tranche B Term Loan which is a LIBOR Term Loan prior to the last day of the Interest Period applicable thereto, the Borrower shall forthwith pay all amounts owing to the Bank pursuant to the provisions of ss.1.9 with respect to such LIBOR Term Loan. Any partial prepayment of principal of the Tranche B Term Loans will be applied to installments of principal of the Tranche B Term Loans thereafter coming due in inverse order of normal maturity. Amounts repaid or prepaid with respect to the Tranche B Term Loans are not available for reborrowing. The Borrower shall repay principal of the Tranche C Term Loans in 41 equal consecutive monthly installments (each in an amount equal to 1/42nd of the aggregate principal amount of the Tranche C Term Loans outstanding at the close of business on March 31, 2000), such monthly installments to commence on April 1, 2000 and to continue on the first day of each month thereafter through and including August 1, 2003, PLUS a 42nd and final installment due and payable on September 1, 2003 in an amount equal to the entire then outstanding principal balance of the Tranche C Term Loans and all interest then accrued but unpaid thereon to the date of payment. The Borrower may prepay, at any time or from time to time, without premium or penalty, the whole or any portion of the Tranche C Term Loans to the extent that same are Floating Rate Term Loans; provided that each such principal prepayment shall be accompanied by payment of all interest on the amount so prepaid accrued under the Tranche C Term Note but unpaid to the date of payment. The Borrower may prepay the whole or any portion of any Tranche C Term Loan which is a LIBOR Term Loan; provided that (i) the Borrower gives the Bank not less than two (2) Business Days' prior written notice of its intent so to prepay, (ii) the Borrower pays all interest on each such Tranche C Term Loan which is a LIBOR Term Loan (or portion thereof) so prepaid accrued to the date of such prepayment, (iii) any voluntary prepayment with respect to a Tranche C Term Loan which is a LIBOR Term Loan must be in an integral multiple of $100,000 (provided that, in any event, no Tranche C Loan which is a LIBOR Term Loan will remain outstanding in a principal amount of less than $100,000), and (iv) if the Borrower for any reason makes any prepayment of a Tranche C Term Loan which is a LIBOR Term Loan prior to the last day of the Interest Period applicable thereto, the Borrower shall 5 forthwith pay all amounts owing to the Bank pursuant to the provisions of ss.1.9 with respect to such LIBOR Term Loan. Any partial prepayment of principal of the Tranche C Term Loans will be applied to installments of principal of the Tranche C Term Loans thereafter coming due in inverse order of normal maturity. Amounts repaid or prepaid with respect to the Tranche C Term Loans are not available for reborrowing. 1.6. INTEREST RATE FOR TERM LOANS. Except as otherwise provided below in this ss.1.6, interest on the Term Loans will be payable at a fluctuating rate per annum (the "Floating Rate") which shall at all times be equal to the Prime Rate as in effect from time to time (but in no event in excess of the maximum rate permitted by then applicable law), with a change in such rate of interest to become effective on each day when a change in the Prime Rate becomes effective. Subject to the conditions set forth herein, the Borrower may elect that all or any portion of any Term Loan to be made under ss.1.4 will be made as a LIBOR Term Loan, that all or any portion of any Floating Rate Term Loan will be converted to a LIBOR Term Loan and/or that any LIBOR Term Loan will be continued at the expiration of the Interest Period applicable thereto as a new LIBOR Term Loan. Such election shall be made by the Borrower giving to the Bank a written or telephonic notice received by the Bank within the time period and containing the information described in the next following sentence (a "LIBOR Term Loan Notice"). The LIBOR Term Loan Notice must be received by the Bank no later than 10:00 a.m. (Boston time) on that day which is two Business Days prior to the date of the proposed borrowing, conversion or continuation, as the case may be, and must specify the amount of the LIBOR Term Loan requested (which shall be an integral multiple of $100,000), must identify the particular Term Loan or Loans or portion thereof so to be made, converted or continued, as the case may be, and must specify the proposed commencement date of the relevant Interest Period. Notwithstanding anything provided elsewhere in this letter agreement, the Borrower may not elect to have any installment of a Term Loan included in a LIBOR Term Loan if the Interest Period applicable thereto would continue after the due date of such installment. Any LIBOR Term Loan Notice shall, upon receipt by the Bank, become irrevocable and binding on the Borrower, and the Borrower shall, upon demand and receipt of a Bank Certificate with respect thereto, forthwith indemnify the Bank against any loss or expense incurred by the Bank as a result of any failure by the Borrower to borrow any requested LIBOR Term Loan, including, without limitation, any loss or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Bank to fund or maintain such LIBOR Term Loan. At the expiration of each Interest Period applicable to a LIBOR Term Loan, the principal amount of such LIBOR Term Loan may be continued as a new LIBOR Term Loan to the extent and on the terms and conditions contained in this letter agreement by delivery to the Bank of a new LIBOR Term Loan Notice conforming to the requirements set forth above in this ss.1.6 (and any LIBOR Term Loan not repaid and not so continued as a new LIBOR Term Loan will be deemed to have been converted into a Floating Rate Term Loan). Notwithstanding any other provision of this letter agreement, the Bank need not make any LIBOR Term Loan or allow any conversion of a Floating Rate Term Loan to a LIBOR Term Loan at any time when there exists any Default or Event of Default. The Borrower may request and the Bank may issue caps, collars, swaps and other rate protection products, using the Bank's then customary documentation for such transactions. Such caps, collars, swaps and other rate protection products will be issued for such fees and upon such 6 other terms and conditions as may be agreed upon by the Bank and the Borrower at the time of issuance thereof. Any request for a LIBOR Term Loan and any election to convert all or any portion of the Term Loans to a LIBOR Term Loan may be made on behalf of the Borrower only by a duly authorized officer; provided, however, that the Bank may conclusively rely upon any written or facsimile communication received from any individual whom the Bank believes in good faith to be such a duly authorized officer. 1.7. INTEREST PAYMENTS ON ALL LOANS. The Borrower will pay interest on the principal amount of the Loans outstanding from time to time, from the date hereof until payment of the Loans and the Notes in full and the termination of this letter agreement. Interest on Demand Loans and on Floating Rate Term Loans will be payable monthly in arrears on the first day of each month. Interest on each LIBOR Term Loan will be payable in arrears on the Interest Payment Date applicable to such LIBOR Term Loan. In any event, interest under each Term Note shall also be paid on the date of payment of such Term Note in full. Interest on Demand Loans and on Floating Rate Term Loans shall be payable at the Floating Rate. The rate of interest payable on any LIBOR Term Loan will be the LIBOR Interest Rate applicable thereto. In any event, after the occurrence and during the continuance of an Event of Default the Loans shall bear interest at a rate per annum which at all times shall be equal to the sum of (i) four (4%) percent per annum PLUS (ii) the Prime Rate in effect from time to time. All interest and fees payable under this letter agreement and/or under any Note will be calculated on the basis of a 360-day year for the actual number of days elapsed. 1.8. RATE DETERMINATION PROTECTION. In the event that: (i) the Bank shall determine that, by reason of circumstances affecting the London interbank market or otherwise, adequate and reasonable methods do not exist for ascertaining the LIBOR Interest Rate which would otherwise be applicable during any Interest Period, or (ii) the Bank shall determine that: (A) the making or continuation of any LIBOR Term Loan has been made impracticable or unlawful by (1) the occurrence of any contingency that materially and adversely affects the London interbank market or (2) compliance by the Bank with any applicable law or governmental regulation, guideline or order or interpretation or change thereof by any governmental authority charged with the interpretation or administration thereof or with any request or directive of any such governmental authority (whether or not having the force of law); or (B) LIBOR (taking into account any adjustment in respect of any Reserve Rate which may become effective) will not, in the reasonable determination of the Bank, adequately and fairly reflect the cost to the Bank of funding the LIBOR Term Loans for such Interest Period 7 then the Bank shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower. In such event the obligations of the Bank to make LIBOR Term Loans shall be suspended until the Bank determines that the circumstances giving rise to such suspension no longer exist, whereupon the Bank shall notify the Borrower. 1.9. PREPAYMENT OF LIBOR TERM LOANS. The following provisions of this ss.1.9 shall be effective only with respect to LIBOR Term Loans: If, due to acceleration of any Term Note or due to voluntary prepayment or mandatory repayment or prepayment or due to any other reason, the Bank receives payment of any principal of any LIBOR Term Loan on any date prior to the last day of the relevant Interest Period or if for any reason any LIBOR Term Loan is converted to a Floating Rate Term Loan prior to the expiration of the relevant Interest Period, the Borrower shall, upon demand and receipt of a Bank Certificate from the Bank with respect thereto, pay forthwith to the Bank a yield maintenance fee in an amount computed as follows: The current rate for United States Treasury securities (bills on a discounted basis shall be converted to a bond equivalent) with a maturity date closest to the last day of the Interest Period applicable to the affected LIBOR Term Loan shall be subtracted from the "cost of funds" component (I.E., reserve-adjusted LIBOR) of the LIBOR Interest Rate in effect with respect to such LIBOR Term Loan at the date of such prepayment or conversion. If the result is zero or a negative number, there shall be no yield maintenance fee. If the result is a positive number, then the resulting percentage shall be multiplied by the amount of the principal balance being prepaid. The resulting amount shall be divided by 360 and multiplied by the number of days remaining in the relevant Interest Period. Said amount shall be reduced to present value calculated by using the number of days remaining in the relevant Interest Period and by using the above-referenced United States Treasury securities rate as the discount rate. The resulting amount shall be the yield maintenance fee due to the Bank upon prepayment or conversion of the applicable LIBOR Term Loan. Any acceleration of a LIBOR Term Loan due to an Event of Default will give rise to a yield maintenance fee calculated with the respect to such LIBOR Term Loan on the date of such acceleration in the same manner as though the Borrower had exercised a right of prepayment at that date, such yield maintenance fee being due and payable at that date. 1.10. INCREASED COSTS; CAPITAL ADEQUACY. (i) If the adoption, effectiveness or phase-in, after the date hereof, of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (A) shall subject the Bank to any Imposition or other charge with respect to any LIBOR Term Loan or the Bank's agreement to make LIBOR Term Loans, or shall change the basis of taxation of payments to the Bank of the principal of or interest on any LIBOR Term Loan or any other amounts due under this letter agreement in respect of the LIBOR Term Loans or the Bank's 8 agreement to make LIBOR Term Loans (except for changes in the rate of tax on the over-all net income of the Bank); or (B) shall impose, modify or deem applicable any reserve, special deposit, deposit insurance or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding, with respect to any LIBOR Term Loan, any such requirement already included in the applicable Reserve Rate) against assets of, deposits with or for the account of, or credit extended by, the Bank or shall impose on the Bank or on the London interbank market any other condition affecting any LIBOR Term Loans or the Bank's agreement to make LIBOR Term Loans and the result of any of the foregoing is to increase the cost to the Bank of making or maintaining any LIBOR Term Loan or to reduce the amount of any sum received or receivable by the Bank under this letter agreement or under any Term Note with respect to any LIBOR Term Loan by an amount deemed by the Bank to be material, then (A) the Bank shall promptly after its determination of such occurrence deliver a Bank Certificate with respect thereto to the Borrower; and (B) promptly upon demand by the Bank and receipt of such Bank Certificate from the Bank with respect thereto, the Borrower shall pay to the Bank such additional amount or amounts as the Bank certifies to be necessary to compensate the Bank for such increased cost or reduction in amount received or receivable. (ii) If the Bank shall have determined that the adoption, effectiveness or phase-in after the date hereof of any applicable law, rule or regulation regarding capital requirements for banks or bank holding companies, or any change therein after the date hereof, or any change after the date hereof in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any request or directive of such entity regarding capital adequacy (whether or not having the force of law) has or would have the effect of reducing the return on the Bank's capital with respect to any Loan (whether or not then subject to any LIBOR Interest Rate) or any letter of credit and/or with respect to the Bank's agreements hereunder to make Loans and/or issue letters of credit to a level below that which the Bank could have achieved (taking into consideration the Bank's policies with respect to capital adequacy immediately before such adoption, effectiveness, phase-in, change or compliance and assuming that the Bank's capital was then fully utilized) by any amount deemed by the Bank to be material: (A) the Bank shall promptly after its determination of such occurrence deliver a Bank Certificate with respect thereto to the Borrower; and (B) the Borrower shall pay to the Bank as an additional fee from time to time on demand such amount as the Bank certifies to be the amount that will compensate it for such reduction. (iii) A Bank Certificate of the Bank claiming compensation under this ss.1.10 shall be conclusive in the absence of manifest error. Such certificate shall set forth the nature and date of the occurrence giving rise to such compensation, the additional amount 9 or amounts to be paid to the Bank hereunder and the method by which such amounts are determined. In determining any such amount, the Bank may use any reasonable averaging and attribution methods. (iv) No failure on the part of the Bank to demand compensation on any one occasion shall constitute a waiver of its right to demand such compensation on any other occasion and no failure on the part of the Bank to deliver any Bank Certificate in a timely manner shall in any way reduce any obligation of the Borrower to the Bank under this ss.1.10; provided, however, that if a Bank Certificate is delivered more than 180 days after the event or circumstance giving rise thereto, the Bank shall not be entitled to compensation under this ss.1.10 with respect to any period more than 180 days prior to the date of delivery of such Bank Certificate. 1.11. ILLEGALITY OR IMPOSSIBILITY. Notwithstanding any other provision of this letter agreement, if the introduction of or any change in or in the interpretation or administration of any law or regulation applicable to the Bank or the Bank's activities in the London interbank market shall make it unlawful, or any central bank or other governmental authority having jurisdiction over the Bank or the Bank's activities in the London interbank market shall assert that it is unlawful, or otherwise make it impossible, for the Bank to perform its obligations hereunder to make LIBOR Term Loans or to continue to fund or maintain LIBOR Term Loans, then on notice thereof and demand therefor by the Bank to the Borrower, (i) the obligation of the Bank to fund LIBOR Term Loans shall terminate and (ii) all affected LIBOR Term Loans shall be deemed to have been converted into Floating Rate Term Loans (with the Borrower to be responsible for any amount payable under ss.1.9 as a consequence of such conversion) at the last day on which such LIBOR Term Loans may legally remain outstanding. Except as provided above in this ss.1.11, the Borrower will have no right to convert any LIBOR Term Loan to a Floating Rate Term Loan prior to the end of the Interest Period applicable to such LIBOR Term Loan. 1.12. ADVANCES AND PAYMENTS. The proceeds of all Loans shall be credited by the Bank to a general deposit account maintained by the Borrower with the Bank. The proceeds of each Demand Loan shall be used by the Borrower solely for working capital purposes. At the date of execution and delivery of this letter agreement, all loans outstanding under the Prior Note are deemed to be refunded by Demand Loans under this letter agreement. The proceeds of each Term Loan will be used by the Borrower solely to pay or reimburse acquisition costs of Qualifying Equipment and/or Qualifying Leasehold Improvements. 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 when same are due, from time to time, under this letter agreement and/or any Note and/or with respect to any letter of credit; and will thereafter promptly 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 any Note or with respect to any letter of credit. 10 Whenever any payment to be made to the Bank hereunder or under any Note or with respect to any letter of credit 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 any Note and/or with respect to any letter of credit 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 any Note and/or with respect to any letter of credit shall be made to the Bank, in lawful money of the United States in immediately available funds, at its office at One Federal Street, Boston, MA 02110 or at 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, any Note and/or any of the other Loan Documents and/or with respect to any letter of credit, next to interest then accrued on account of any Loans or letter of credit reimbursement obligations and only thereafter to principal of the Loans and letter of credit reimbursement obligations, being applied against the Loans and/or such obligations in such order as the Borrower may designate (and, failing such designation, being applied first against the letter of credit reimbursement obligations, next against any outstanding Demand Loans and thereafter against installments of the Term Loans in inverse order of normal maturity). All interest and fees payable hereunder and/or under any Note shall be calculated on the basis of a 360-day year for the actual number of days elapsed. 1.13. LETTERS OF CREDIT. At the Borrower's request, the Bank may, from time to time, in its sole discretion issue one or more letters of credit for the account of the Borrower; provided that at the time of issuance of such letter of credit and after giving effect thereto, the Aggregate Demand Facility Liabilities will not exceed $3,000,000. Any such letter of credit will be issued for such fee and upon such terms and conditions as may be agreed to by the Bank and the Borrower at the time of issuance. The Borrower hereby authorizes the Bank, without further request from the Borrower, to cause the Borrower's liability to the Bank for reimbursement of funds drawn under any such letter of credit to be repaid from the proceeds of a Demand Loan to be made hereunder. The Borrower hereby irrevocably requests that such Demand Loan be made. 1.14. CONDITIONS TO ADVANCE. Prior to the making of the initial Loan hereunder or the issuance of any letter of credit hereunder, the Borrower shall deliver to the Bank duly executed copies of this letter agreement, the Security Agreement, the Demand Note, the Tranche A Term Note, the Tranche B Term Note, the Tranche C 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. Without limiting the foregoing, any Loan or letter of credit issuance (including the initial Loan or letter of credit issuance) is subject to the further conditions precedent that on the date on which such Loan is made or such letter of credit is issued (and after giving effect thereto): 11 (a) All statements, representations and warranties of the Borrower made in this letter agreement and/or in the Security Agreement shall continue to be correct in all material respects as of the date of such Loan or issuance of such letter of credit, as the case may be. (b) All covenants and agreements of the Borrower contained herein and/or in any of the other Loan Documents shall have been complied with in all material respects on and as of the date of such Loan or issuance of such letter of credit, as the case may be. (c) No event which constitutes, or which with notice or lapse of time or both could constitute, an Event of Default shall have occurred and be continuing. (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 Loan or for the issuance of a letter of credit, and each acceptance by the Borrower of the proceeds of any Loan or delivery of a letter of credit, will be deemed a representation and warranty by the Borrower that at the date of such Loan or letter of credit issuance, as the case may be, and after giving effect thereto all of the conditions set forth in the foregoing clauses (a)-(d) of this ss.1.14 will be satisfied. II. REPRESENTATIONS AND WARRANTIES 2.1. REPRESENTATIONS AND WARRANTIES. In order to induce the Bank to enter into this letter agreement and to make Loans hereunder and/or issue letters of credit hereunder, the Borrower warrants and represents to the Bank as follows: (a) The Borrower is a corporation duly organized, validly existing and in good standing under the laws of Delaware. The Borrower has full corporate power to own its property and conduct its business as now conducted and as contemplated to be conducted, to grant the security interests contemplated by the Security Agreement and to enter into and perform this letter agreement and the other Loan Documents. The Borrower is duly qualified to do business and in good standing in Massachusetts and in each other jurisdiction in which the Borrower maintains any facility, sales office or warehouse and in each other jurisdiction where the failure so to qualify could (singly or in the aggregate with all other such failures) have a material adverse effect on the financial condition, business or prospects of the Borrower, all such jurisdictions, as at the date of this letter agreement, being listed on item 2.1(a) of the attached Disclosure Schedule. At the date hereof, the Borrower has no Subsidiaries, except as shown on said item 2.1(a) of the attached Disclosure Schedule. The Borrower is not a member of any partnership or joint venture. (b) At the date of this letter agreement, no Person is known by the Borrower to own, of record and/or beneficially, more than 5% of the outstanding shares of any class of the Borrower's capital stock, except as set forth on item 2.1(b) of the attached Disclosure Schedule. The Borrower owns 100% of the outstanding capital stock of each Subsidiary. 12 (c) The execution, delivery and performance by the Borrower of this letter agreement and each of the other Loan Documents have been duly authorized by all necessary corporate and other action and do not and will not: (i) violate any provision of, or require any filings (other than filings under the Uniform Commercial Code), registration, consent or approval under, any law, rule, regulation, order, writ, judgment, injunction, decree, determination or award presently in effect having applicability to the Borrower; (ii) violate any provision of the charter or by-laws of the Borrower, or result in a breach of or constitute a default or require any waiver or consent under any indenture or loan or credit agreement or any other material agreement, lease or instrument to which the Borrower is a party or by which the Borrower or any of its properties may be bound or affected or require any other consent of any Person; or (iii) result in, or require, the creation or imposition of any lien, security interest or other encumbrance (other than in favor of the Bank), upon or with respect to any of the properties now owned or hereafter acquired by the Borrower. (d) This letter agreement and each of the other Loan Documents has been duly executed and delivered by the Borrower and each is a legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its respective terms. (e) Except as described on item 2.1(e) of the attached Disclosure Schedule, there are no actions, suits, proceedings or investigations pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any Subsidiary of the Borrower before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which could hinder or prevent the consummation of the transactions contemplated hereby or call into question the validity of this letter agreement or any of the other Loan Documents or any other instrument provided for or contemplated by this letter agreement or any of the other Loan Documents or any action taken or to be taken in connection with the transactions contemplated hereby or thereby or which in any single case or in the aggregate could result in any material adverse change in the business, prospects, condition, affairs or operations of the Borrower or any such Subsidiary. (f) The Borrower is not in violation of any term of its charter or by-laws as now in effect. Neither the Borrower nor any Subsidiary of the Borrower is in material violation of any term of any mortgage, indenture or judgment, decree or order, or any other instrument, contract or agreement to which it is a party or by which any of its property is bound. (g) The Borrower has filed (and has caused each Subsidiary of the Borrower to file) all federal, foreign, state and local tax returns, reports and estimates required to be filed by the Borrower or by any such Subsidiary. All such filed returns, reports and estimates are proper and accurate and the Borrower (or the Subsidiary concerned, as the case may be) has paid all taxes, assessments, impositions, fees and other governmental charges required to be paid in respect of the periods covered by such returns, reports or estimates. No deficiencies for any tax, 13 assessment or governmental charge have been asserted or assessed, and the Borrower knows of no material tax liability or basis therefor. (h) The Borrower is in compliance with (and each Subsidiary of the Borrower is in compliance with) all requirements of law, federal, state and local, and all requirements of all governmental bodies or agencies having jurisdiction over it, the conduct of its business, the use of its properties and assets, and all premises occupied by it, failure to comply with which could (singly or in the aggregate with all other such failures) have a material adverse effect upon the assets, business, financial condition or prospects of the Borrower or any such Subsidiary. Without limiting the foregoing, the Borrower has all the franchises, licenses, leases, permits, certificates and authorizations needed for the conduct of its business and the use of its properties and all premises occupied by it, as now conducted, owned and used and as proposed to be conducted, owned and used. (i) The audited financial statements of the Borrower as at March 31, 1999 and the management-generated financial statements of the Borrower as at June 30, 1999, each heretofore delivered to the Bank, are complete and accurate and fairly present the financial condition of the Borrower as at the date thereof and for the period covered thereby, except that the aforesaid management-generated statements do not have footnotes and thus do not present the information which would normally be contained in footnotes to financial statements and are subject to normal year-end audit adjustments. Neither the Borrower nor any of the Borrower's Subsidiaries has any liability, contingent or otherwise, not disclosed in the aforesaid financial statements or in the notes thereto that could materially affect the financial condition of the Borrower. Since March 31, 1999, there has been no material adverse development in the business or condition of the Borrower, and the Borrower has not entered into any transaction other than in the ordinary course. (j) The principal place of business and chief executive offices of the Borrower are located at 22 Cherry Hill Drive, Danvers, MA 01923. All of the books and records of the Borrower are located at 22 Cherry Hill Drive and/or at 33 Cherry Hill Drive, Danvers, MA 01923. Except as described on item 2.1(j) of the attached Disclosure Schedule, no Collateral is located at any other address. Said item 2.1(j) of the attached Disclosure Schedule sets forth the names and addresses of all record owners of any premises where any material amount of Collateral is located. (k) Except as described on item 2.1(k) of attached Disclosure Schedule, the Borrower owns or has a valid right to use all of the patents, licenses, copyrights, trademarks, trade names and franchises now being used or necessary to conduct its business. To the best knowledge of the Borrower, the conduct of the Borrower's business as now operated does not conflict with valid patents, licenses, copyrights, trademarks, trade names or franchises of others in any manner that could materially adversely affect the business or assets or condition, financial or otherwise, of the Borrower. (l) To the best knowledge of the Borrower, none of the executive officers or key employees of the Borrower is subject to any agreement in favor of anyone other than the Borrower which limits or restricts that person's right to engage in the type of business activity 14 conducted or proposed to be conducted by the Borrower or which grants to anyone other than the Borrower any rights in any inventions or other ideas susceptible to legal protection developed or conceived by any such officer or key employee. (m) The Borrower is not a party to any contract or agreement which now has or, as far as can be reasonably foreseen by the Borrower at the date hereof, may have a material adverse effect on the financial condition, business, prospects or properties of the Borrower. (n) As used herein, the term "Year 2000 Issue" refers to the concern that computers, software and other equipment utilizing microprocessors may be unable to recognize and perform properly date-sensitive functions involving certain dates prior to and any date on or after December 31, 1999. The Borrower has evaluated this potential issue with respect to its products, its financial and management information systems and its suppliers. With respect to the Borrower's products, the software controlling the BVS drive console includes internal counters, but the BVS operation is not related in any way to a specific calendar date. Accordingly, the Borrower believes that the BVS will not need any repair or modification with regard to the Year 2000 issue. With respect to the Borrower's financial and management information systems, the Borrower successfully installed and tested a Year 2000 upgrade to its primary system and is currently working on execution of a plan to ensure that all personal computers ("PCs") and applications are fully assessed and updated to be Year 2000 compliant before the end of 1999. To date, expenditures for new Pcs, software applications, and operating systems under the Borrower's Year 2000 plan have amounted to less than $100,000. Remaining expenditures to complete the plan are expected to be immaterial. With respect to its suppliers, the Borrower is completing an assessment of vendors begun in fiscal 1999 and is increasing safety stocks of materials and inventory where a prolonged loss of material and inventory deliveries would have an adverse impact on the Borrower's business, financial condition and results of operations. The Borrower has also made inquiries to assess its key service providers such as its financial institutions, its payroll service provider, and its retirement plan administrator as to their Year 2000 readiness and has received assurances that the vendors' critical systems have been updated, tested, and found to be compliant. Although the Borrower's management does not expect Year 2000 Issues to have a material impact on its business or future results of operations, there may be interruptions of operations or other limitations of system functionality or the Borrower may incur significant costs to avoid such interruptions or limitations. To the extent that the Borrower does not eliminate all Year 2000 Issues, the most likely worst case Year 2000 scenario is systemic failures beyond the control of the Borrower, such as prolonged telecommunications or electrical failure, or a general disruption in supplies and services provided to the Borrower which could have a material adverse effect on the Borrower's business, results of operations and financial condition. The Borrower will, at the request of the Bank, provide such reports and such other information as the Bank may reasonably request in order to evidence such Year 2000 compliance. 15 III. AFFIRMATIVE COVENANTS AND REPORTING REQUIREMENTS Without limitation of any covenants and agreements contained in the Security Agreement or elsewhere, the Borrower agrees that so long as the financing arrangements contemplated hereby are in effect or any Demand Loan or any Term Loan or any of the other Obligations shall be outstanding or any letter of credit issued hereunder shall be outstanding: 3.1.

The Borrower will comply with (and will cause each Subsidiary of the Borrower to comply with) its charter documents and by-laws. The Borrower will comply with (and will cause each Subsidiary of the Borrower to comply with) all applicable laws, rules and regulations (including, without limitation, ERISA and those relating to environmental protection) other than (i) laws, rules or regulations the validity or applicability of which the Borrower or such Subsidiary shall be contesting in good faith by proceedings which serve as a matter of law to stay the enforcement thereof and (ii) those laws, rules and regulations the failure to comply with any of which could not (singly or in the aggregate) have a material adverse effect on the financial condition, business or prospects of the Borrower or any such Subsidiary. 3.2. MAINTENANCE OF PROPERTY; INSURANCE. The Borrower will maintain and preserve (and will cause each Subsidiary of the Borrower to maintain and preserve) all of its properties in good working order and condition, making all necessary repairs thereto and replacements thereof. The Borrower will maintain all such insurance as may be required under the Security Agreement and will also maintain, with financially sound and reputable insurers, insurance with respect to its property and business against such liabilities, casualties and contingencies and of such types and in such amounts as shall be reasonably satisfactory to the Bank from time to time and in any event all such insurance as may from time to time be customary for companies conducting a business similar to that of the Borrower in similar locales. 3.3. PAYMENT OF TAXES AND CHARGES. The Borrower will pay and discharge (and will cause each Subsidiary of the Borrower to pay and discharge) all taxes, assessments and governmental charges or levies imposed upon it or upon its income or property, including, without limitation, taxes, assessments, charges or levies relating to real and personal property, franchises, income, unemployment, old age benefits, withholding, or sales or use, prior to the date on which penalties would attach thereto, and all lawful claims (whether for any of the foregoing or otherwise) which, if unpaid, might give rise to a lien upon any property of the Borrower or any such Subsidiary, except any of the foregoing which is being contested in good faith and by appropriate proceedings which serve as a matter of law to stay the enforcement 16 thereof and for which the Borrower has established and is maintaining adequate reserves. The Borrower will pay, and will cause each of its Subsidiaries to pay, in a timely manner, all lease obligations, all material trade debt, purchase money obligations, equipment lease obligations and all of its other material Indebtedness. The Borrower will perform and fulfill all material covenants and agreements under any leases of real estate, agreements relating to purchase money debt, equipment leases and other material contracts. The Borrower will maintain in full force and effect, and comply with the terms and conditions of, all permits, permissions and licenses necessary or desirable for its business. 3.4. ACCOUNTS. The Borrower will maintain its principal depository and operating accounts with the Bank. 3.5. CONDUCT OF BUSINESS. The Borrower will conduct, in the ordinary course, the business in which it is presently engaged. The Borrower will not, without the prior written consent of the Bank, directly or indirectly (itself or through any Subsidiary), enter into any other lines of business, businesses or ventures. 3.6.

Such income statements shall be accompanied by a comparison to budget and a comparison to the results for the corresponding period of the immediately prior fiscal year.

Each such certificate given as at the end of any fiscal quarter shall also set forth the calculations necessary to evidence compliance with ss.ss.3.7-3.9. (iv) Promptly after receipt, a copy of all audits or reports submitted to the Borrower by independent public accountants in connection with any annual, special or interim audits of the books of the Borrower and any "management letter" prepared by such accountants.

(viii) Promptly after receiving notice of the commencement thereof, notice of all actions, suits and proceedings before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, brought against the Borrower or any Subsidiary of the Borrower; provided, however, that this clause (viii) will not be deemed to require the Borrower to give notice of FDA proceedings occurring in the ordinary course of the Borrower's business (including, without limitation, product recalls in the ordinary course) which could not reasonably be expected to have a material adverse effect on the Borrower's financial condition, business or prospects. (ix) Promptly after the Borrower has knowledge thereof, written notice of any development or circumstance which may reasonably be expected to have a material adverse effect on the Borrower or its business, properties, assets, Subsidiaries or condition, financial or otherwise.

BOOKS AND RECORDS.

GUARANTIES.

"Interest Period" - As to each LIBOR Term Loan, the period commencing with the date of the making of such LIBOR Term Loan and ending three months thereafter; provided that (A) any such Interest Period which would otherwise end on a day which is not a Business Day shall be extended to the next succeeding Business Day unless such Business Day occurs in a new calendar month, in which case such Interest Period shall end on the immediately preceding Business Day, (B) any such Interest Period which begins on a day for which there is no numerically corresponding day in the calendar month during which such Interest Period is to end shall end on the last Business Day of such calendar month, and (C) no Interest Period may be selected as to any principal amount of any Term Loan if such Interest Period would end after the regularly-scheduled due date of such principal amount. 33 "LIBOR" - With respect to each Interest Period for a LIBOR Term Loan, that rate per annum (rounded upward, if necessary, to the nearest 1/32nd of one percent) which represents the offered rate for deposits in U.S. Dollars, for a period of time comparable to such Interest Period, which appears on the Telerate page 3750 as of 11:00 a.m. (London time) on that day that is two (2) London Banking Days preceding the first day of such Interest Period; provided, however, that if the rate described above does not appear on the Telerate System on any applicable interest determination date, LIBOR for such Interest Period shall be the rate (rounded upwards as described above, if necessary) for deposits in dollars for a period substantially equal to such Interest Period shown on the Reuters Page "LIBO" (or such other page as may replace the LIBO Page on that service for the purpose of displaying such rates), as of 11:00 a.m. (London Time), on that day that is two (2) London Banking Days prior to the beginning of such Interest Period. "London Banking Day" shall mean any date on which commercial banks are open for business in London. If both the Telerate and Reuters systems are unavailable, then LIBOR for any Interest Period will be determined on the basis of the offered rates for deposits in U.S. Dollars for a period of time comparable to such Interest Period which are offered by four major banks in the London interbank market at approximately 11:00 a.m., London time, on that day that is two (2) London Banking Days preceding the first day of such Interest Period, as selected by the Bank. The principal London office of each of four major London banks will be requested to provide a quotation of its U.S. Dollar deposit offered rate. If at least two such quotations are provided, the rate for that date will be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that date will be determined on the basis of the rates quoted for loans in U.S. Dollars to leading European banks for a period of time comparable to such Interest Period offered by major banks in New York City at approximately 11:00 a.m., New York City time, on that day that is two London Banking Days preceding the first day of such Interest Period. In the event that the Bank is unable to obtain any such quotation as provided above, it will be deemed that LIBOR for the proposed Interest Period cannot be determined. The Bank shall give prompt notice to the Borrower of LIBOR as determined for each LIBOR Term Loan and such notice shall be deemed conclusively correct, absent manifest error.
