The Company shall pay interest on the unpaid principal amount of each Credit Loan made by the Bank from the date of such Credit Loan until such principal amount shall be paid in full as follows: 4 (a) (i) During such periods as any LIBOR Rate Loan is outstanding, at a rate per annum equal to the sum of the LIBOR Rate and the LIBOR Rate Margin (as described in subpart (b) below) in effect from time to time from and after each Margin Adjustment Date occurring on or prior to the date of the making, the conversion or the continuation of such Loan, as the case may be, in accordance with this Agreement, (ii) during such periods as any Federal Funds Effective Rate Loan is outstanding, at a rate per annum equal at all times to the sum of the Federal Funds Effective Rate plus two hundred (200) basis points, and (iii) during such periods as any Prime Rate Loan is outstanding, at a rate per annum equal at all times to the sum of the Prime Rate plus twenty five (25) basis points. (b) (i) Except as otherwise provided herein, the LIBOR Rate Margin in effect shall be adjusted as of the first day of each calendar quarter, beginning with January 1, 2000 (each a "Margin Adjustment Date"), in accordance with Section 2.5(b)(ii) below. The LIBOR Rate Margin in effect shall be applicable to new advances for Credit Loans as of the date of such advances, and to a converted or continued Loan as of the date of conversion or continuation, occurring within the calendar quarter in which such LIBOR Rate Margin is in effect. With respect to any LIBOR Rate Loan for which the last day of the Interest Period is a date subsequent to the Margin Adjustment Date, such LIBOR Rate Margin shall not be applicable until the continuation date of such LIBOR Rate Loan, if applicable, subsequent to the Margin Adjustment Date. (ii) As of any Margin Adjustment Date, the LIBOR Rate Margin shall be adjusted to be the percentage indicated in the following table corresponding to the ratio of the Company's Indebtedness to its Tangible Net Worth, which shall be calculated from the quarterly balance sheet most recently provided by the Company to the Bank under Section 8.l(a) hereof: Ratio LIBOR Rate Margin ----- ----------------- <1.00 to 1.00 100 Basis Points >=1.00 to 1.00 but <2.00 to 1.00 125 Basis Points >=2.00 to 1.00 but <3.00 to 1.00 150 Basis Points >=3.00 to 1.00 200 Basis Points (iii) Any such adjustment to the LIBOR Rate Margin shall only remain effective until the earlier of the next Margin Adjustment Date or the date on which an Event of Default shall occur. The LIBOR Rate Margin to be effective from such earlier date and from time to time thereafter shall be the LIBOR Rate Margin as adjusted pursuant to this Agreement, PROVIDED, HOWEVER, that: (i) if the Company shall not deliver its financial statements in accordance with Section 8.1 of this Agreement, the LIBOR Rate Margin shall be two hundred (200) basis points per annum and (ii) if an Event of Default shall occur which has not been waived in writing by the Bank, the interest rate shall be the interest rate applicable pursuant to subsection (c) below. (c) Upon the occurrence of any Event of Default and so long as such Event of Default is continuing (excepting therefrom an Event of Default created by the Company's failure to deliver 5 its financial statements in accordance with Section 8.1 of this Agreement) (i) the unpaid principal amount of each Federal Funds Effective Rate Loan or Prime Rate Loan, and accrued interest thereon, or any fees or any and other sum payable hereunder, shall thereafter until paid in full bear interest at a rate per annum equal to six hundred (600) basis points in excess of the Federal Funds Effective Rate in effect from time to time, and (ii) the unpaid principal amount of each Prime Rate Loan, and accrued interest thereon, or any fees or any and other sum payable hereunder, shall thereafter until paid in full bear interest at a rate per annum equal to six hundred (600) basis points in excess of the Prime Rate in effect from time to time. SECTION 2.6 INTEREST PAYMENTS. The Company shall pay to the Bank interest on the unpaid principal balance of each Federal Funds Effective Rate Loan on either (i) the date such Loan is converted to a LIBOR Rate Loan, or (ii) the last day of each March, June, September and December. The Company shall pay to the Bank interest on the unpaid principal balance of each LIBOR Rate Loan on (i) the date such Loan is converted to a Federal Funds Effective Rate Loan, or (ii) the last day of the applicable Interest Period of such Loan, whichever is earlier. The Company shall pay to the Bank interest on the unpaid principal balance of each Prime Rate Loan on the last day of each March, June, September and December. SECTION 2.7 PRINCIPAL PAYMENTS. (a) Commencing September 30, 1999, and on the last day of each calendar quarter thereafter, the aggregate principal amount available under the Acquisition Line shall be permanently reduced by the amount of $259,090.91, and the Company shall immediately pay to the Bank the amount, if any, by which the aggregate principal amount outstanding under the Acquisition Line exceeds such reduced commitment of the Bank at that time. If, after giving effect to any such payment any LIBOR Rate Loan would be prepaid prior to the end of its applicable Interest Period, the Company shall pay the Bank the breakage fee required under Section 2.11(c) hereof. (b) Commencing September 30, 1999, and on the 1st day of each calendar quarter thereafter, the aggregate principal amount available under the Accommodation Line shall be permanently reduced by the amount of $230,000 and the Company shall immediately pay to the Bank the amount, if any, by which the aggregate principal amount outstanding under the Accommodation Line exceeds such reduced commitment of the Bank at that time. (c) On the Accommodation Line Maturity Date, the Acquisition Line Maturity Date and the Working Capital Line Maturity Date, all amounts outstanding under the Accommodation Line, the Acquisition Line and the Working Capital Line, respectively, shall be immediately due and payable. If payment of the outstanding Loans at maturity causes any LIBOR Rate Loan to be prepaid prior to the end of its applicable Interest Period, the Company shall pay the Bank the breakage fee required under Section 2.11(c) hereof. 6 SECTION 2.8 PREPAYMENT. (a) VOLUNTARY PREPAYMENT. The Company may prepay any Federal Funds Effective Rate Loan or Prime Rate Loan in whole, or in part, at any time or times. The Company may prepay any LIBOR Rate Loan, in whole or in part, only on the last day of the Interest Period applicable to such LIBOR Rate Loan upon not less than three (3) Business Days' prior written notice given to the Bank. (b) MANDATORY PREPAYMENT. Without notice or demand, if the sum of the outstanding principal balance of Loans made under Section 2.1(b) hereof shall at any time exceed the Borrowing Base, the Company shall immediately prepay such Loans to the extent necessary to eliminate such excess. Any payment received by the Lender under this Section 2.8(b) or under 2.8(a) may be applied to the Obligations, in such order and in such amounts as the Bank, in its discretion, may from time to time determine. If, after giving effect to any such payment any LIBOR Rate Loan would be prepaid prior to the end of its applicable Interest Period, the Company shall pay the Bank the breakage fee required under Section 2.11(c) hereof. (c) FREE CASH FLOW RECAPTURE. Within ninety (90) days of the end of each fiscal year of the Company commencing with the Company's fiscal year ending on December 31, 1999, the Company shall make a principal payment in respect of the outstanding Loans in an amount equal to fifty percent (50%) of the Company's Free Cash Flow for such fiscal year. Such payment shall be applied first to the Accommodation Line and any remainder shall be applied to the Acquisition Line, and the aggregate principal amount available under the Accommodation Line and the Acquisition Line, as applicable, shall be permanently reduced in such amount. If, after giving effect to any such payment any LIBOR Rate Loan would be prepaid prior to the end of its applicable Interest Period, the Company shall pay the Bank the breakage fee required under Section 2.11(c) hereof. (d) PREPAYMENT UPON SIGNIFICANT SALE OF ASSETS. Without notice or demand, if the Company sells, leases, transfers or otherwise disposes of any plant or any manufacturing facility or other assets in any single transaction involving amounts exceeding $250,000, the Company shall immediately prepay the Loans in the full amount of the consideration (whether cash or otherwise) received by the Company in respect of such sale. Such prepayment shall be applied to the Credit Lines in such proportions as the Company shall direct, but such application shall not effect a permanent reduction to the applicable credit facility. If, after giving effect to any such prepayment, any LIBOR Rate Loan would be prepaid prior to the end of its applicable Interest Period, the Company shall pay the Bank the breakage fee required under Section 2.11(c) hereof. 2.
