The principal amount of the Term Note shall be payable in 15 equal consecutive quarterly installments, each in the amount of $26,315.27, payable on the last business day of each fiscal quarter of Del, commencing October 31, 1997 and continuing thereafter until the entire unpaid principal balance of the Term Note, together with all accrued and unpaid interest, shall be paid in full on the Term Loan Maturity Date.

Section 2.4(a). Section 2.4(a) of the Agreement is hereby deleted as of the Second Amendment Date and the following substituted therefor: 2.4 Interest. (a) Interest shall accrue on the outstanding and unpaid principal amount of each Loan for the period from the Second Amendment Date to but excluding the date such Loan is due at the following rates per annum: (i) for a Variable Rate Loan, at a variable rate per annum equal to the Variable Rate plus the applicable Margin, (ii) for a Eurodollar Loan, at a fixed rate equal to the Eurodollar Rate plus the applicable Margin, and (iii) for a Fixed Rate Loan, at the applicable Fixed Rate. Interest shall be calculated on the basis of a year of 360 days for the actual number of days elapsed. After any stated or accelerated maturity thereof, each Note shall bear interest (computed daily on the basis of a 360-day year for actual days elapsed) at a rate of one percent (1%) per annum in excess of the rate hereinbefore provided for. In no event shall interest be payable at a rate which is in excess of the maximum rate of interest permitted under applicable law. 6. Section 2.4(c). Section 2.4(c) of the Agreement is hereby deleted as of the Second Amendment Date and the following substituted therefor: (c) Subject to the terms and conditions of this paragraph and elsewhere in this Agreement, the Debtors may convert any Variable Rate Loan or portion thereof to a Eurodollar Loan or to a Fixed Rate Loan, and, at the end of the Interest Period therefor, convert any Eurodollar Loan or Fixed Rate Loan to a Loan of another type. (i) In the case of each Eurodollar Loan, the Debtors shall select an Interest Period of any duration in accordance with the definition of Interest Period in Section 1.1, subject to the following limitations: (A) no Interest Period may extend beyond the Termination Date; and (B) if an Interest Period would end on a day which is not a Business Day, such Interest Period shall be extended to the next Business Day, unless such Business Day would fall in the next calendar month in which event such Interest Period shall end on the immediately preceding Business Day. In the case of a Term Loan, interest rates based on the Eurodollar Rate shall not be available to the Debtors at such times or in such amounts as would require prepayment of a Eurodollar Loan in order to satisfy the amortization requirements set forth in the Note evidencing such Term Loan. No Eurodollar Loan (Eurodollar Loans having different Interest Periods at the same time hereunder being deemed separate Eurodollar Loans) may be in an amount less than $250,000.00 (or the U.S. Dollar equivalent). Upon notice to the Bank as provided in Section 2.15, the Debtors may renew any Eurodollar Loan on the last day of the Interest Period therefor as a Eurodollar Loan with an Interest Period of the same or different duration in accordance with the limitations provided above. If the Debtors shall fail to give notice to the Bank of such a renewal, such Eurodollar Loan shall automatically become a Variable Rate Loan on the last day of the current Interest Period. (ii) In the case of each Fixed Rate Loan, upon request therefor by the Debtors and subject to the Bank's sole and absolute discretion, the Bank shall make available to the Debtors a Fixed Rate for a designated Interest Period which shall not extend beyond the Termination Date. In the case of a Term Loan, a Fixed Rate shall not be available to the Debtors at such times or in such amounts as would require prepayment of a Fixed Rate Loan in order to satisfy the amortization requirements set forth in the Note evidencing such Term Loan. Upon notice to the Bank as provided in Section 2.15 and subject to the Bank's sole discretion, the Debtors may renew any Fixed Rate Loan on the last day of the Interest Period therefor as a Fixed Rate Loan with an Interest Period of the same or different duration in accordance with the limitations provided above. If the Debtors shall fail to give notice to the Bank of such a renewal, such Fixed Rate Loan shall automatically become a Variable Rate Loan on the last day of the current Interest Period. 7. Section 2.4(f). Section 2.4(f) of the Agreement is hereby deleted as of the Second Amendment Date and the following substituted therefor: (f) Accrued interest shall be due and payable in arrears upon any payment of principal or conversion and (i) for each Variable Rate Loan and each Fixed Rate Loan, on the first day of each calendar month, commencing the first such date after such Loan and (ii) for each Eurodollar Loan, on the last day of the Interest Period with respect thereto and, in the case of an Interest Period greater than three months, at three-month intervals after the first day of such Interest Period provided that interest accruing after any stated or accelerated maturity of a Note shall be due and payable from time to time on demand of the Bank. 8. Section 2.9(a). Section 2.9(a) of the Agreement is hereby deleted as of the Second Amendment Date and the following substituted therefor: (a) Subject to the terms and conditions contained in this Section 2.9 and elsewhere in this Agreement, the Debtors shall have the right to prepay any Term Loan, at any time in whole or from time to time in part; provided that (i) each optional partial prepayment, except for prepayments which result in the prepayment of all outstanding principal of such Loan, shall be in a principal amount of not less than One Hundred Thousand Dollars ($100,000.00) and shall be applied to installments in inverse order of their maturities; (ii) in the case of a Eurodollar Loan or a Fixed Rate Loan, payment or conversion may occur only on the last day of an Interest Period for such Loan. 9.
