The Borrower has also requested that the Bank extend to the Borrower a $2,500,000.00 term loan for purposes of partially financing the Borrower's purchase of the assets of CNS, Inc. The Bank is agreeable to meeting the Borrower's requests provided that each credit facility extended is subject to the terms and conditions of this Agreement.

Reference is made to the Revolving Note for terms relating to interest rate, repayment and other conditions governing the Line. 1.4 Mandatory Prepayment.

The Cost of Funds Interest Period will be any period of time mutually agreed to by the Bank and the Borrower. The Borrower must orally accept a quote at the time of receipt or it will be deemed rejected. If accepted, the Cost of Funds Rate Option will remain in effect for the Cost of Funds Interest Period specified in the quote. At the end of each Cost of Funds Interest Period the principal amount subject to the Cost of Funds Rate Portion shall bear interest at the Base Rate Option (as defined in the Replacement Note). 4.3 Performance Based Rate Reductions / Premiums. The Borrower, depending on its financial performance as measured under the performance standards set forth in Sections 4.3(a) or (c), may be entitled to a reduced rate of interest on its borrowings under the Replacement Note and the Term Note, or may be subject to the payment of a rate premium on such borrowings. (a) Rate Reduction. The Bank shall discount the otherwise applicable rate of interest in effect at any time under the Replacement Note or under the Term Note by 0.29% at any time after August 1, 1996 if the Borrower's performance meets or exceeds all of the following criteria as certified annually by the Borrower's certified public accountants in a certificate addressed to the Bank: 1) the Borrower's net income after taxes exceeds $575,000.00 for each quarter of the fiscal year preceding the year in which net income is measured, for each fiscal quarter of the current fiscal year, and for each fiscal quarter of the following fiscal year as projected under the financial projection provided to the Bank to Section 8.1(e) of this Agreement; 2) the Borrower remains in compliance with all covenants set forth in this Agreement regardless of whether any default is waived or cured by the Bank, with the exception of Section 8.1(d); 3) the Borrower's "B Score", or ratio of after tax net income plus depreciation plus amortization to total liabilities, is greater than 0.40 to 1.0. (this ratio shall be calculated on a rolling basis at the end of each month using the results of that month and each of the eleven immediately preceding months). (b) Effective Date or Cancellation Date of Rate Reduction: Any rate reduction shall become effective on either August 1st or the date on which the Bank receives from the Borrower's certified public accountants the certificate of compliance described in Section 4.3(a), whichever is later. The rate reduction shall be canceled by the Bank, based on its review of the Borrower's interim financial statements effective on the first day of the quarterly reporting period following the quarterly period in which the Borrower fails to meet the rate reduction performance criteria. (c) Rate Increase. The Bank shall increase the otherwise applicable rate of interest in effect at any time under the Replacement Note or under the Term Note by 0.63% whenever the Bank determines from its review of the Borrower's interim financial statements that the Borrower has failed to comply with the following minimum performance criteria in any fiscal quarter: 1) the Borrower's after tax net income is less than $250,000.00; 2) the Borrower's B Score is less than 0.25 to 1.0.

All principal, interest and fees due under the Documents will be paid to the Bank by the direct debit of available funds on deposit in the Borrower's account with the Bank. The Bank will debit the account on the dates the payments become due. If a due date does not fall on a day on which the Bank is open for substantially all of its business (a "Banking Day"), the Bank will debit the account on the next Banking Day and interest will continue to accrue during the extended period. If there are insufficient funds in the account on the day the Bank enters any debit authorized by this Agreement, the debit will be reversed and the payment will be due immediately without necessity of demand by direct remittance of immediately available funds. 5.
