AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) Note 1. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-QSB. Accordingly, they do not include all of the financial information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (including normal recurring adjustments) considered necessary for a fair presentation have been included. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The results of operations for the respective interim periods are not necessarily indicative of the results to be expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Form 10-KSB for the year ended December 31, 1998 filed with the Securities and Exchange Commission. Note 2. Net Loss Per Common Share Effective for the year ended December 31, 1997, the Company adopted Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"). The Company's basic and diluted earnings per share are equal, due to the exclusion of common stock equivalents, which would make the earnings per share calculations anti-dilutive. Note 3. Inventories Inventories consist of the following: March 31, 1999 Raw materials $ 941,825 Work in process 46,621 Finished goods 839,875 -------------- $ 1,828,321 ============== Note 4. Long-Term Debt Effective March 31, 1999, the Company entered into two debt agreements with a bank: a $2,000,000 revolving line of credit ("revolver") and a $500,000 term note. 6 The proceeds of the revolver, when drawn down are intended to fund future working capital needs. Borrowings bear interest at either the bank's Prime Rate plus 1/2% or LIBOR plus 3%. A facility fee is payable quarterly on the average unused commitment at a rate of 3/4%. The purpose of the term note is to fund the purchase of 7,500 square feet of manufacturing and warehouse space at the Company's ProCath subsidiary and building improvements. Interest is payable monthly in arrears at either Prime plus 3/4% or LIBOR plus 3 1/4%. Principal is payable commencing January 2000 in 48 equal monthly installments under a 15 year amortization schedule with a balloon payment due in December 2004. The Company is required to maintain certain financial ratios, and meet certain net worth and indebtedness tests. The debt is collateralized by a first priority lien on all corporate assets. The agreement also prohibits the Company from incurring certain additional indebtedness, limits investments, advances or loans and restricts substantial asset sales, capital expenditures and cash dividends. Item 2. Management's Discussion and Analysis or Plan of Operation Overview The Company was incorporated in New Jersey in January 1993 and operates in a single industry segment. The Company develops, manufactures, markets and sells a line of products for the cardiac electrophysiology ("EP") market used to diagnose, monitor and treat irregular heartbeats known as arrhythmias. Since inception, the Company has acquired technology, has developed new products and has begun marketing various electrophysiology products, including the EP WorkMate[REGISTERED] electrophysiology workstation, the EP-3[TRADEMARK] Stimulator, diagnostic electrophysiology catheters, internal cardioversion catheters and related disposable supplies. The Company has developed a new product for internal cardioversion of atrial fibrillation known as the ALERT[REGISTERED] System, which uses a patented electrode catheter to deliver measured, variable, low energy electrical impulses directly to the inside of the heart in order to convert atrial fibrillation to a normal heart rhythm. The ALERT[REGISTERED] System is not approved for sale in the United States, but is currently undergoing clinical trials. The Company intends to market a full family of internal cardioversion catheters around the ALERT[REGISTERED] platform. The Company has also developed an intracardiac ultrasound product line including the ViewMate[TRADEMARK] ultrasound imaging console and U-View[TRADEMARK] deflectable intracardiac imaging catheter. These products are designed to improve a physician's ability to visualize inside the chambers of the heart, including the internal anatomy of the heart. The Company believes that the ViewMate[TRADEMARK] and U-View[TRADEMARK] may play an important role as new and effective treatment options are developed for the treatment of complex cardiac arrhythmias, including ventricular tachyarrhythmia and atrial fibrillation. The 7 Company's ultrasound products are not approved for sale and the Company does not anticipate receiving approval to sell the ViewMate[TRADEMARK] or U-View[TRADEMARK] for at least several months, if approved at all. Forward-Looking Statements This report contains certain statements of a forward-looking nature relating to such matters as anticipated financial and operational performance, business prospects, technological developments, results of clinical trials, new products, research and development activities and similar matters. Stockholders are cautioned that such statements are only predictions and that actual events or results may differ materially. In evaluating such statements, prospective investors should specifically consider the various factors effecting the industry and economy generally, as well as those identified in this report and in the Company's other reports filed with the Securities and Exchange Commission, which could cause actual results to differ materially from those indicated by such forward-looking statements. RESULTS OF OPERATIONS Three months ended March 31, 1999 compared to three months ended March 31, 1998 Sales increased $1,080,000 (or 74%) in the three months ended March 31, 1999 as compared to the prior period in 1998. The majority of the increase in revenue in the quarter resulted from increased sales of the EP WorkMate[REGISTERED], which represented a substantial percentage of sales during the three-month period in 1999. The Company also realized increased sales of certain of its catheter products during the period. The level of sales for the remaining nine months of 1999 will depend materially on sales of the EP WorkMate[REGISTERED] and diagnostic catheters and the ability of the Company's direct sales force and network of international independent distributors to effectively market and sell the Company's existing products. The ALERT[REGISTERED] System is currently undergoing clinical trials and is not approved for sale in the United States. The ALERT[REGISTERED] System has been introduced for sale in Europe. However, the Company cannot accurately determine the sales level of the ALERT[REGISTERED] System for the remaining quarters in 1999 at this time or when it will be available at all in the United States. The Company expects the ALERT[REGISTERED] System to contribute a greater proportion of revenues in the second half of 1999 and beyond. Cost of products sold increased $306,000 (or 35%) due to the 74% increase in sales for the three months ended March 31, 1999 as compared to 1998. Gross profit on sales for the three months ended March 31, 1999 was $1,341,000 (or 53% as a percentage of sales), as compared with $568,000 (or 39% as a percentage of product sales) for the comparable period in 1998. The Company realized an increase in gross profit on sales of existing products during first quarter 1999 primarily due to increased sales of the EP WorkMate, which currently yields a higher gross margin than certain of the Company's other products. The Company 8 hopes to improve its overall gross profit percentage as sales of the ALERT[REGISTERED] System and other catheter products increase, which may offset the fixed costs associated with maintaining a catheter manufacturing operation. Sales and marketing expenses increased $371,000 (or 53%), but decreased as a percentage of revenue from product sales from 48% to 42% in the three months ended March 31, 1999 as compared to 1998. The dollar increase during first quarter 1999 was primarily due to the impact of expanding the domestic sales force from 6 employees as of March 31, 1998 to 9 employees as of March 31, 1999 and the increase in travel, trade show related expenses, product promotion and physician educational materials in support of its sales efforts. The international distribution network is currently supported by a team of direct international sales and marketing professionals, international field clinical engineers and administrative support personnel. General and administrative expenses increased $249,000 (or 72%) and remained at 24% of sales revenue in the three months ended March 31, 1999 as compared to 1998. The increase during first quarter 1999 was due to increased personnel, occupancy and other administrative costs necessary to support the increased operations. It is anticipated that these expenses may decline as a percentage of revenues as incremental sales are generated. Research and development expenses increased $95,000 (or 27%)%), but decreased as a percentage of revenue from product sales from 23% to 18% in the three months ended March 31, 1999 as compared to 1998. in the three months ended March 31, 1999 as compared to 1998. During the three months ended March 31, 1999, the Company incurred research and development expenses in connection with ongoing development efforts on existing products, including the EP WorkMate[REGISTERED], costs associated with the clinical trials for the ALERT[REGISTERED] System, development costs and costs of preparing regulatory submissions for the new ultrasound imaging product line, as well as costs associated with several new products under development. The Company expects that research and development expenses are likely to increase in future periods, in part due to ongoing expenses related to the ALERT[REGISTERED] System clinical trials, new product development activities and regulatory applications aimed at gaining approval to sell other new products. The net loss for the three months ended March 31, 1999 was $744,000 as compared to a net loss of $795,000 during the comparable period in first quarter 1998. The basic and diluted loss per share for the three months ended March 31, 1999 was $0.08 per share as compared to $.10 in first quarter 1998. Liquidity and Capital Resources Since inception, the Company's expenses have exceeded its sales, resulting in an accumulated deficit of approximately $15,179,000 at March 31, 1999. The Company entered into two financing arrangements in March of 1999 with a bank: a $2,000,000 revolving line of credit and a $500,000 term loan. Management believes that its current liquidity position will be sufficient to meet the 9 needs of the Company until at least March 31, 2000. In the event that it cannot generate additional capital funds during 1999, the Company believes that it can reduce non-core related expenditures, which will allow it to continue in its operations for a significant period. Net cash used in operating activities for the three months ended March 31, 1999 decreased $377,000 (or 38%) as compared to 1998. The net use of cash in operations during first quarter 1999 was primarily due to the Company's loss from operations. Payables to related parties increased $257,000 due to an increase in purchases of components for the Alert[REGISTERED] System. Payments to related parties are made on terms similar to those of other suppliers. Accrued expenses payable decreased by $150,000. Capital expenditures, were $535,000 during first quarter 1999 as compared to $59,000 in first quarter 1998. During February 1999, the Company purchased an additional 7,500 square feet of manufacturing and warehouse space at ProCath for a purchase price of approximately $400,000. Costs to prepare the space for intended use are estimated to be $100,000. This purchase was financed via a $500,000 term loan executed subsequent to December 31, 1998. The purchase provided for expansion of the existing manufacturing operations, additional warehousing, shipping and quality assurance activities and relocation of ProCath's administrative offices. Net borrowings under note payable increased $508,000 as compared to first quarter 1998 due to the proceeds the Company received from the $500,000 term loan. As of the date of this Report on Form 10-QSB, the Company does not have any other material commitments for capital expenditures. However, the Company expects to purchase capital equipment and to expand its manufacturing and assembly capabilities as it continues to grow. The Company leases office and manufacturing space and certain office equipment under operating leases. During February 1997, the Company licensed the rights to several ultrasound technologies from EchoCath, for use in the field of electrophysiology. The agreement with EchoCath calls for the Company to make payments totaling up to a maximum of $700,000, in four installments, as certain development milestones and initial sales are achieved on the EchoMark and EchoEye technologies. One of the milestones calls for a $400,000 payment payable upon the completion of a development program for the EchoEye. This milestone was only payable in the event that the development was completed by September 30, 1998. To the best of the Company's knowledge, the milestone was not achieved and no milestone payments are accrued or payable to EchoCath as of March 31, 1999. The Company expects its operating losses to continue in the near future as it will continue to expend substantial funds for research and development, clinical trials in support of regulatory approvals, increased manufacturing capacity and expansion of sales and marketing activities. The amount and timing of future losses will be dependent upon, among other things, increased sales of the Company's existing products, clinical approval and market acceptance of the ALERT[REGISTERED] System and developmental, regulatory and market success of new 10 products under development. There can be no assurance that any of the Company's development projects will be successful or that if development is successful, that the products will generate any sales. Based upon its current plans and projections, the Company believes that its existing capital resources will be sufficient to meet its anticipated capital needs for at least the next twelve months. Year 2000 Readiness The Year 2000 issue could affect computers, software and other equipment used, operated or maintained by the Company. The Company has substantially completed a review of its internal computer programs and systems to ensure that the programs and systems will be Year 2000 compliant. The Company presently believes that, based on current plans and efforts to date, its internal programs and systems will be Year 2000 compliant in a timely manner. The Year 2000 issue can also affect products sold by the Company, particularly the EP WorkMate[REGISTERED] and ALERT[REGISTERED] Companion. The Company has performed an assessment of its products and, as a result of this review, believes that it has substantially identified and resolved the potential Year 2000 issues with these products. However, the Company also believes that it is not possible to determine with complete certainty that all Year 2000 issues affecting the Company's products have been identified or corrected due to the complexity of these products and the fact that these products interact with other third party products or operate on computer systems which are not under the Company's control. The Company believes that its greatest Year 2000 risk for disruption to its business is the potential noncompliance of third parties. In this regard, the Company has initiated communications with its vendors, major customers and service providers in order to determine the extent to which the Company's business is vulnerable to the third parties' failure to make their systems Year 2000 compliant. Since the Company has no control over the actions of these third parties, there can be no assurance that these third parties will resolve any or all Year 2000 issues. Any failure of these third parties to resolve Year 2000 issues in a timely manner could have a material adverse effect on the Company's financial condition and results of operations. The Company currently does not have a contingency plan in the event that particular systems, including the systems of material third parties, are not Year 2000 compliant. It is intended that such a plan will be developed if it becomes clear that the Company is not going to achieve its scheduled compliance objectives. Although no assurance can be given that there will be no interruption of operations as a result of the Year 2000 issue, the Company believes and assuming that third parties with whom the Company has material business relationships successfully remediate their own Year 2000 issues) that it has reasonably assessed its systems in order to ensure that the Company will not suffer any material adverse effect from the Year 2000 issue. Though the Company has used and will continue to use internal resources to resolve its Year 2000 issues, the Company may retain third party consultants to assist in this regard. 11 Costs specifically associated with Year 2000 compliance are expensed as incurred. To date, the Company has not spent a material amount on this project. The Company does not expect the total costs relating to Year 2000 compliance to have a material effect on the Company's results of operations or financial condition. However, the total costs that the Company will incur in connection with the Year 2000 issue will be influenced by (i) its ability to successfully identify Year 2000 issues, (ii) the nature and amount of programming required to remediate the issues, (iii) the related labor and/or consulting costs for such remediation and (iv) the ability of third parties with whom the Company has business relationships to successfully address their own Year 2000 concerns. These and other unforeseen factors could have a material adverse effect on the Company's results of operations or financial condition. PART II. OTHER INFORMATION Item 1. Legal Proceedings. During October 1997, the Company filed a lawsuit against EchoCath in the United States District Court for the District of New Jersey alleging, among other things, that EchoCath made fraudulent misrepresentations and omissions in connection with the prior sale of $1,400,000 of its preferred stock to the Company. EchoCath filed an answer to the complaint, denying the allegations and asserting a counterclaim against the Company seeking its costs and expenses in the action. EchoCath also filed a motion to dismiss the complaint. During October 1998, the complaint was dismissed by the District Court. The Company is appealing the decision. The Company believes that EchoCath's counterclaim and request for reimbursement of its costs and expenses is without merit. As a result, the Company has not accrued for such costs and expenses at March 31, 1999. In the opinion of management, the ultimate resolution of the counterclaim will not have a material adverse impact of the Company's financial condition or results of operations. The Company cannot determine the outcome of the EchoCath litigation at this time. Item 2. Changes in Securities None. Item 3. Defaults Upon Senior Securities None. Item 4.

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 $2,000,000 face principal amount revolving promissory note (the "Revolving Note") of even date herewith made by the Borrower and payable to the order of the Bank; (ii) that certain $500,000 face principal amount term promissory note (the "Term Note") of even date herewith made by Borrower and payable to the order of the Bank; (iii) the Disclosure Schedule to this Letter Agreement of even date herewith; and (iv) the Closing Agenda, of even date herewith. 1.2 Revolving Loans; Revolving Note. Subject to the terms and conditions hereinafter set forth, the Bank will make loans ("Revolving 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 earlier termination of the within-described revolving financing arrangements pursuant to [SECTION]5.2 or [SECTION]6.7; provided, however, that (1) the aggregate principal amount of Revolving Loans outstanding shall at no time exceed the Maximum Revolving Amount (hereinafter defined) and (2) the Aggregate Revolving Bank Liabilities (hereinafter defined) shall at no time exceed the Borrowing Base (hereinafter defined). Within such limits, and subject to the terms and conditions hereof, the Borrower may obtain Revolving Loans, repay Revolving Loans and obtain Revolving Loans again on one or more occasions. The Revolving Loans shall be evidenced by the Revolving Note and interest thereon shall be payable at the times and at the rate provided for in the Revolving Note. Overdue principal of the Revolving Loans 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) four (4%) percent per annum plus (ii) the per annum rate otherwise payable under the Revolving 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 Revolving Note or on the books of the Bank, at or following the time of making each Revolving Loan and of receiving any payment of principal, an appropriate notation reflecting such transaction and the then aggregate unpaid principal balance of the Revolving Loans. The amount so noted shall constitute presumptive evidence as to the amount owed by the Borrower with respect to principal of the Revolving 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 Revolving Note. 1.3 Repayment; Renewal of Revolving Loan Facility. The Borrower shall repay in full all Revolving Loans and all interest thereon upon the first to occur of: (i) the Expiration Date, or (ii) 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 Revolving Loan. In addition, if at any time the Borrowing Base is in an amount which is less than the then outstanding Aggregate Revolving Bank Liabilities, the Borrower will forthwith prepay so much of the Revolving Loans as may be required (or arrange for termination of such letters of credit as may be required) so that the Aggregate Revolving Bank Liabilities will not exceed the Borrowing Base. The Bank may, at its sole discretion, renew the revolving financing arrangements described in this Letter Agreement 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 Note. In addition to the foregoing, the Bank may make one or more loans (the "Term Loans") to the Borrower in an aggregate principal amount up to $500,000. A Term Loan shall be made, no more than once per calendar quarter (except that more than one Term Loan may be made in any calendar quarter provided that any 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 or Qualifying Real Property acquired by the Borrower within the 90 days preceding the request for such Term Loan, each Term Loan to be in such amount as may be requested by the Borrower; provided that (i) no Term Loan will be made after the earlier of (A) December 31, 1999 or (b) the earlier termination of the within-described term loan facility, pursuant to [SECTION]5.2 or [SECTION]7.7; (ii) the aggregate original principal amounts of all Term Loans will not exceed $500,000; and (iii) no Term Loan will be in an amount more than 80% of the Fair Market Value of Qualifying Real Property (excluding appraisals, environmental assessments and reports, insurance and other closing costs); or 80% of the 2 invoiced actual costs of the tangible property of equipment and/or fixtures 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"); or 30% of the invoiced actual costs of software. Prior to the making of each Term Loan, and as a precondition thereto, the Borrower will provide the Bank with: (i) appraisals, environmental assessments and reports, title reports and other information of the relevant Qualifying Real Property or invoices supporting the costs of the relevant Qualifying Equipment; or (ii) such evidence as the Bank may reasonably require showing that the Qualifying Equipment has been delivered to and installed at the 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 provided for herein); or (iii) Uniform Commercial Code financing statements. If needed, reflecting the relevant Qualifying Equipment or Qualifying Real Property with respect to which such Term Loan is being made; and (iv) evidence Satisfactory to the Bank that the Qualifying Equipment or Qualifying Real Property 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) four (4%) 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 Bank hereunder or under the Term Note. 1.5 Principal Repayment of Term Loans. The Borrower shall repay principal of each Term Loan in 47 equal consecutive monthly installments (each in an amount equal to 1/180th of the aggregate principal amount of the Term Loans outstanding at the close of business on December 31, 1999) commencing on January 31, 2000 and continuing on the last Business Day of each month through November 30, 2004 plus a 48th and final payment of all remaining principal and unpaid interest due and payable on December 31, 2004. In any event, the then outstanding principal balance of each Term Loan and all interest then accrued but unpaid thereon shall be due and payable in full no later than December 31, 2004. 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 on the sum so prepaid 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. 1.6 Interest Rates and Payment. Interest on the Revolving Loans and on the 3 Term Loans shall be calculated as follows: (a) Except as otherwise provided below in this [SECTION]1.6, interest on the Revolving Loans and on the Term Loans will be payable monthly in arrears as provided in the Notes at a fluctuating rate per annum (the "Floating Rate") which shall at all times be equal to the sum of (i) (A) for the Revolving Loans, one half of one percent (0.50%); or (B) for the Term Loans, there quarters of one percent (0.75%) plus (ii) the Prime Rate as defined in the Notes in effects 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. (b) Subject to the conditions set forth herein, the Borrower may elect that all or a portion of any Revolving Loan to be made under [SECTION]1.2 or any Term Loan to be made under [SECTION]1.4 be made as a London Interbank Offered Rate ("LIBOR") Loan at the rate of (i) (A) for a Revolving Loan, three percent (3%); or (B) for a Term Loan, three and one quarter percent (3.25%) plus (ii) 30, 60 or 90 day LIBOR (as the Borrower may select), as provided for in the Notes; that all or any portion of any Floating Rate Loan will be converted to a 30, 60 or 90 day (as the Borrower may select) LIBOR Loan at such rates; and/or that any LIBOR Loan will be continued at the expiration of the Interest Period, as defined herein, as a 30, 60 or 90 day (as the Borrower may select) new LIBOR Loan. As used herein, "Interest Period" shall mean , with respect to each such advance conversion or continuation, the chosen 30,60 or 90 day period commencing on and including the date on which such advance, conversion or continuation is made and ending on and including the date preceding the next succeeding date, when payment of interest is due, or, if such interest payment date should fall within thirty (30) days of the date of such advance, conversion or continuation, the net interest payment date thereafter. (c) A LIBOR Loan 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 Borrowing Notice"). The LIBOR Borrowing 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 any such advance conversion or continuation, and must specify: (i) the amount of the LIBOR Loan requested (which shall be $500,000 or an integral multiple of $100,000 in excess of $500,000; (ii) the particular Term Loan(s) or Revolving Loan(s) to be so advanced, converted or continued, as the case may be; and (iii) the proposed commencement date of the relevant Interest Period and its 30, 60 or 90 day duration. The Bank shall determine the LIBOR as quoted to it by leading banks in the London Interbank Eurodollar Market, at or about 5:00 p.m. (London time) on the date a LIBOR Borrowing Notice is received (or, if such date is a banking holiday in London, of the last LIBOR quoted to the Bank), which will be in effect on the date of the advance, conversion or continuation as the case may be (which in any case must be a Business Day) with respect to the Term Loan or Revolving Loan or LIBOR Loan in question, having a maturity date of 30, 60 or 90 days from the date of the advance, conversion or continuation, as the case may be. Each determination of LIBOR by the Bank shall be conclusive evidence, in the absence of manifest error, or such LIBOR and 4 shall be promptly communicated to the Borrower. However, if the Borrower if the Borrower has not delivered a notice to the Bank in a timely manner in accordance with the provisions of this [SECTION]1.6 (c), the Borrower shall be deemed to have chosen to have the interest on such Revolving Loan or Term Loan or LIBOR Loan calculated on the applicable Floating Rate basis. Any LIBOR Borrowing 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 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 Loan. Notwithstanding the foregoing, the Bank need not make a LIBOR Loan, convert a Floating Rate Loan to a LIBOR Loan or continue a LIBOR Loan at any time at which there exists an Event of Default. (d) Nothing contained herein shall be construed as authorizing the Borrower, with respect to the determination of LIBOR (i) to choose a LIBOR Interest Period in respect of which the Interest Period extends beyond the Expiration Date in the case of Revolving Loans or beyond the due date of the applicable installment in the case of Term Loans; or (ii) to choose an amount for an advance, conversion or continuation amount greater than that permitted under [SECTION]1.2 for Revolving Loans or [SECTION]1.4 for Term Loans. (e) The actual annual rate of interest to which the rates determined in accordance with [SECTION]1.6(b) are equivalent is the specified rate multiplied by the actual number of days during the year, divided by 360: (LIBOR + Margin) x 365*/360 = % per year * (in a leap year, substitute 366 for 365). LIBOR Loan interest shall be payable in arrears on each applicable Interest Period payment date. (f) In the event that the Bank determines that (i) for any reason, adequate and reasonable methods for determining the LIBOR applicable to any Interest Period do not exist; or (ii) the making, conversion to or continuation of LIBOR Loan has been made impracticable or unlawful by reason of London Interbank market conditions or events or by compliance by the Bank with any applicable law, regulation, guideline or other or change of, or change in the interpretation of, any such law, regulation, guideline or order; or (iii) LIBOR, in the Bank's reasonable determination, does not adequately and fairly reflect the Bank's cost in funding such LIBOR Loans for such Interest Period, then the Bank shall give Borrower notice of such determination, which shall be conclusive and binding on Borrower, and the Bank's obligation to make LIBOR Loans shall be suspended until the Bank determines that the conditions that gave rise to its prior determination no longer exist. (g) If, due to acceleration or prepayment (whether voluntary or mandatory) or for any other reason, the Bank receives payment for any principal of any LIBOR Loan on any date prior to the last day of such LIBOR Loan's relevant Interest Period, the Borrower shall, upon receipt of a Bank Certificate from the Bank with respect thereto, pay forthwith to the Bank a yield 5 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 Loan shall be subtracted from the "cost of funds" component (i.e., reserve-adjusted LIBOR) of the fixed rate in effect 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. Such 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 the Bank upon prepayment or conversion of the applicable LIBOR Loan. Any acceleration of a LIBOR Loan due to an Event of Default will give rise to a yield maintenance fee calculated with respect to such LIBOR 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. 1.7 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 Revolving Loan will be used by the Borrower solely for working capital purposes. The proceeds of each Term Loan will be used by the Borrower solely to pay or reimburse acquisition costs of Qualifying Equipment or Qualifying Real Property. 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 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 overdue principal, overdue interest or default interest as provided herein or in any Note or with respect to any letter of credit. 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 any 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 letterof 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, 7th Floor, 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 6 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 next to interest then accrued on account of any Loans or letter of credit reimbursement obligations and only thereafter to principal of the Loans or 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 the Revolving Loans and thereafter against installments of the Term Loans in inverse order of normal maturity). All interest and fees payable hereunder and/or under nay Note shall be calculated on the basis of a 360-day year for the actual number of days elapsed. 1.8 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 such issuance and after giving effect thereto the Aggregate Revolving Bank Liabilities will in no event exceed the lesser of (i) Borrower or (ii) the then effective Borrowing Base. 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 Revolving Loan to be made thereunder. The Borrower hereby irrevocably requests that such Revolving Loans be made. 1.9 Conditions to Advance.

All of the property and rights set forth in (a) through (e) above, including, without limitation, all proceeds of fire and other insurance thereon, are hereinafter referred to collectively as "Collateral." 6.2 Obligations Secured. The Collateral and all proceeds and products thereof shall be security for all Obligations. Until all Obligations have been fully satisfied. Bank's security interest in the Collateral, and all proceeds and products thereof, shall continue in full force and effect and Bank will at all times after the occurrence and during the continuance of an Event of Default (as defined herein) have the right to take physical possession of the Inventory and other Collateral and to maintain such possession on Borrower's premises or to remove the Inventory and other Collateral or any part thereof to such other places as Bank may desire. If Bank exercises Bank's right to take possession of the Inventory and other Collateral, Borrower shall, upon Bank's demand, assemble the Inventory and other Collateral and make it available to Bank at a place reasonably convenient to Bank. 6.3 No Disposal of Collateral. Except for sales, licenses and leases made in the ordinary course of business on a non-exclusive basis and the disposal of obsolete or worn-out equipment made in the ordinary course of business, Borrower shall not sell, license, assign, lease, grant a Lien on or dispose of or permit the sale, license, lease, establishment of a Lien on or disposal of any Collateral or remove any Inventory from the Premises without Bank's prior written consent.

Borrower shall sign and file, or permit the filing, in form and substance satisfactory to the Bank, of the financing statements and shall perform any and all steps requested by Bank to perfect Bank's security interest in the Collateral, such as, without limitation, leasing warehouses to Bank or its designee, placing and maintaining signs and appointing custodians. This Letter Agreement, coupled with the filing of such UCC Financing statements with the filing offices and public authorities set forth in the Closing Agenda (which are the only locations for filing required by the UCC), creates in the Bank's favor a valid and perfected first priority security interest in the Collateral, which security interest secures the Obligations. If any Inventory is in the possession or control of any of Borrower's agents or processors, Borrower shall notify such agents or processors of Bank's interest therein, and upon request instruct them to hold all such Inventory for Bank's account and subject to Bank's instructions. A physical 24 listing of all Inventory, wherever located, shall be taken by Borrower whenever requested by Bank, and a copy of each such physical listing shall be supplied to Bank. Bank may examine and inspect the Inventory and other Collateral on or off the Premises at any time on reasonable notice and during business hours or at any time without any necessity for notice following the occurrence of an Event of Default. 6.5 Insurance. Borrower agrees to keep all the Inventory and Collateral insured with fire and extended coverage as insurance policies in amounts: (i) not less than that usually carried by one engaged in a like business; (ii) sufficient to provide for full replacement cost coverage; and (iii) in any event not less than that required by Bank naming the Bank as secured party and first loss payee. Borrower hereby appoints Bank as attorney for Borrower in obtaining, adjusting, settling and canceling such insurance and endorsing any drafts. All premiums on such insurance shall be paid by Borrower and the policies delivered to the Bank. If Borrower fails to do so, the Bank may procure such insurance and charge the cost to Borrower's loan account. As further assurance for the payment and performance of the Obligations. Borrower hereby assigns to Bank all sums including returned or unearned premiums, which may become payable under any policy of insurance on the Collateral and Borrower hereby directs each insurance company issuing any such policy to make payment of such sums directly to Bank. 6.6 Right to Discharge. Bank may, at its sole option, discharge any taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral and not permitted by this Letter Agreement and pay for the maintenance and preservation of the Collaterals. Borrower will reimburse Bank on demand for any payment made or any expense incurred with interest at the rate provided in this Letter Agreement. Where practical and consistent with its rights to take such actions to preserve or protect the Collateral, the Bank will give Borrower reasonable notice of its intention to take such actions. 6.7 Deficiency.

If the Bank shall have determined that the adoption 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 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 the law) has or would have the effect of reducing the return on the Bank's capital with respect to the Revolving Loans, the Term Loans, LIBOR Loans and/or the within described revolving and Term Loan facilities and/or letters of credit issued for the account of the Borrower 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, phase-in, change or compliance and assuming the Bank's capital was then fully utilized) but for such adoption, phase-in, change of compliance by any amount deemed by the Bank to be material: (i) the Bank shall promptly after its determination of such occurrence give notice thereof to the Borrower; and (ii) the Borrower shall pay forthwith to the Bank as an additional fee such amount as the Bank certifies to be the amount that will compensate it for such reduction with respect to the Revolving Loans, the Term Loans, the LIBOR loans (excluding, with respect to any LIBOR loan, any such requirement already included in such LIBOR loan's reserve rate), the within-described revolving and Term Loan facilities and/or such letters of credit. A certificate of the Bank claiming compensation on under this Section shall be conclusive in the absence of manifest error. Such certificate shall set forth the nature of the occurrence giving rise to such compensation, the additional amount or amounts to be paid to it hereunder and the method by which such amounts were determined. In determining such amounts, the Bank may use any reasonable averaging and attribution methods. 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 certificate in a timely manner shall reduce any obligation of the Borrower to the Bank under this Section. 27 7.3 Facility Fees. With respect to the Term Loans, the Borrower is paying to the Bank, at closing, a non-refundable facility fee in the amount of $3,750. The Borrower will pay to the Bank with respect to the within arrangements for Revolving Loans, on the last day of each calendar quarter (commencing on March 31, 1999 as long as the within-described revolving loan arrangements are in effect and on the Expiration Date, non-refundable commitment fees, computed quarterly in arrears on the daily average unused portion of the revolving credit amount during the calendar quarter for which such commitment fees are to be determined, appropriately prorate for any partial calendar quarter.
