The Borrowers shall pay to the Bank interest on the unpaid principal balance of the aggregate outstanding balance of the Revolving Credit Loans which are Prime Rate Loans or ABS Rate Loans, in arrears, on the first (1st) day of the first (1st) full calendar month after the Closing Date and on the first day of each calendar month thereafter through and including the Expiry Date. The Borrower shall pay to the Bank interest on the unpaid principal balance of the aggregate outstanding balance of the Revolving Credit Loans which are Libor Rate Loans or As-Offered Rate Loans on the earlier of (i) the last day of the applicable Interest Period for such Loan or (ii) for such Loans with an applicable Interest Period exceeding three (3) months, on each and every three (3) month anniversary of each such Loan during the period from the Closing Date to and including the Expiry Date. After maturity of any part of the Loans (whether upon the occurrence of an Event of Default, by acceleration or otherwise), interest on such part of the Loans shall be immediately due and payable upon delivery by Bank of an invoice for such interest without further notice, presentment, or demand. 2.04 Interest After Default; Usury. Whenever the unpaid principal amount of the Loans or any portion thereof, accrued interest thereon, any fees, or any other sums payable hereunder shall become due and payable and remain unpaid (whether at maturity, upon the occurrence of an Event of Default, by acceleration or otherwise) the amount thereof shall thereafter until paid in full bear interest at a rate per annum two percent (2.00%) in excess of the interest rate otherwise applicable to such Loans. In the event the rates of interest provided for in this section 2.04, or any other section of this Agreement, are finally determined by any Official Body to exceed the maximum rate of interest permitted by applicable usury or similar laws, their or its application will be suspended and there will be charged instead the maximum rate of interest permitted by such laws. 2.05 [Reserved] 2.06 Fees. The Borrowers shall pay to Bank a commitment fee on the unused portion of the Revolving Credit Facility Commitment during the period from the date of this Agreement to the Expiry Date, payable quarterly in arrears beginning on July 1, 1997 and continuing on the first (1st) day of each October, January, April and July thereafter and on the Expiry Date. Such fee shall be equal to the amount by which Twenty-Five Million and 00/100 Dollars ($25,000,000.00) has exceeded the average daily closing principal balance of the Revolving Credit Loans (including the Letter of Credit Face Amount of all outstanding Letters of Credit) during the preceding calendar quarter, multiplied by three hundred and seventy-five one-hundredths of one percent (0.375%), multiplied by a fraction, the numerator of which is the actual number of days in such calendar quarter and the denominator of which is 360. 2.07 Computation of Interest and Fees; Adjustment to Prime Rate and ABS Rate. Interest on the Prime Rate Loans shall be computed on the basis of a year of three hundred sixty-five (365) days and paid for the actual number of days elapsed. Interest on all other Loans shall be computed on the basis of a year of three hundred sixty (360) days and paid for the actual number of days elapsed. Interest on unpaid fees and other sums payable hereunder shall be computed on the basis of a year of three hundred sixty five (365) days and paid for the actual number of days elapsed. In the event of any change in the Prime Rate or the ABS Rate, the rate of interest upon each Prime Rate Loan or ABS Rate Loan shall be adjusted to immediately correspond with such change; except any interest charged hereunder shall not exceed the highest rate permitted by law. 2.08 Agreement to Issue Letters of Credit. From time to time during the period from the Closing Date to the Business Day immediately preceding the Expiry Date, subject to the further terms and conditions hereof, including those required in connection with the making of Revolving Credit Loans, the Bank shall issue standby or trade letters of credit (collectively, "Letters of Credit") for the account of the Borrowers in an amount not to exceed Twenty-Five Million and 00/100 Dollars ($25,000,000.00), as a sub-facility of the Revolving Credit Facility Commitment; provided, however, that on any date on which the Borrowers' request a Letter of Credit, and after giving effect to the Letter of Credit Face Amount of such Letter of Credit, the sum of all Revolving Credit Loans outstanding, plus the total Letter of Credit Face Amount of all Letters of Credit issued and outstanding shall not exceed the Revolving Credit Facility Commitment. All such Letters of Credit shall be issued by the Bank in accordance with its then current practice relating to the issuance of letters of credit including, but not limited to, the execution and delivery to Bank of applications and agreements required by Bank and the payment by the Borrowers of all applicable fees with respect thereto. As of the Effective Date, those letters of credit set forth on Schedule 2.08 hereof (the "Existing Letters of Credit") which were issued under the Prior Loan Agreement and are outstanding will be deemed to have been issued and be Letters of Credit issued and outstanding hereunder. 2.09 Letter of Credit Fees. The Borrowers shall pay to Bank (a) one percent (1.00%) per annum of the Letter of Credit Face Amount of all Letters of Credit issued and outstanding hereunder, such fee to be paid quarterly in arrears, (b) the Bank's standard issuance fees for each Letter of Credit issued hereunder, such fee to be paid on the date of issuance of such Letter of Credit, and (c) any reasonable out-of-pocket expenses and costs incurred by Bank for the issuance of any Letter of Credit issued hereunder, such fees to be paid on the day of issuance of such Letter of Credit. 2.10 Payments Under Letters of Credit. Upon a draw under any Letter of Credit, the Borrowers irrevocably authorize Bank to treat such draw as a request for a Revolving Credit Loan which shall be a Prime Rate Loan in the amount of such draw, so long as the Revolving Credit Facility Commitment has not terminated. 2.11 Period of Issuance and Term of Letters of Credit. Letters of Credit shall only be issued by Bank for the account of the Borrowers for such terms which expire prior to or on the Expiry Date. 2.12 [Reserved] 2.13 Additional Costs. (a) If, due to either (i) the introduction of, or any change in, or in the interpretation of, any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to, or reduction in income receivable by, the Bank of making, funding or maintaining Loans (or commitments to make the Loans), then the Borrowers shall from time to time, upon demand by the Bank made within a reasonable time after Bank's determination thereof, pay to the Bank additional amounts sufficient to reimburse such Bank for any such additional costs or reduction in income. All such additional amounts shall be determined by Bank in good faith using appropriate attribution and averaging methods ordinarily employed by the Bank. A certificate of the Bank submitted to the Borrowers in good faith as to the amount of such additional costs shall be presumptive evidence of such amount. Upon notice from the Bank to the Borrowers within ten (10) Business Days after the Bank notifies the Borrowers of any such additional costs pursuant to this Section 2.13(a), the Borrowers may (A) repay in full all Loans of any types so affected then outstanding, together with interest accrued thereon to the date of such repayment, or (B) convert all Loans of any types so affected then outstanding into Loans of any other type not so affected upon not less than four (4) Business Days' notice to the Bank. If any such repayment or conversion of any Libor Rate Loan or As Offered Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in section 2.13(c). (b) If either (i) the introduction of, or any change in, or in the interpretation of, any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), affects or would affect the amount of capital required or expected to be maintained by the Bank or any corporation controlling the Bank and the Bank reasonably determines in good faith that the amount of such capital is increased by or based upon the existence of the Loans (or commitment to make the Loans), then, within ten (10) Business Days of demand by the Bank, the Borrowers shall pay to the Bank from time to time as specified by the Bank additional amounts sufficient to compensate the Bank in the light of such circumstances, to the extent that the Bank reasonably determines in good faith such increase in capital to be allocable to the existence of the Bank's Loans (or commitment to make the Loans). Any such demand by Bank must be made by the Bank within a reasonable time. A certificate of the Bank in good faith submitted to the Borrowers as to such amounts shall be presumptive evidence of such amounts. Upon notice from the Borrowers to the Bank within ten (10) Business Days after the Bank notifies the Borrowers of any such additional costs pursuant to this Section 2.13(b), the Borrowers may (A) prepay in full all Loans of any types so affected then outstanding, together with interest accrued thereon to the date of such prepayment, or (B) convert all Loans of any types so affected then outstanding into Loans of any other type not so affected upon not less than four (4) Business Days' notice to the Bank. If any such prepayment or conversion of any Libor Rate Loan or As Offered Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in section 2.13(c). (c) If the Borrowers shall repay any Libor Rate Loan or As Offered Rate Loan on a day other than the last day of the applicable Interest Period for such Loan (whether such repayment is permitted by Section 2.13 or 2.14, as a result of the failure of the Borrowers to consummate a transaction after providing notice as set forth in Section 2.01(c)(ii) and (iii), otherwise permitted by Bank or otherwise required under the terms of this Agreement), the Borrowers shall within ten (10) Business Days of demand pay to the Bank such additional amounts reasonably determined by Bank in good faith to be sufficient to indemnify the Bank against any loss, cost, or expense incurred by the Bank as a result of such prepayment including, without limitation, any loss (including loss of anticipated profits), costs or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by the Bank to fund such Loan, and a certificate as to the amount of any such loss, cost or expense submitted by the Bank to the Borrowers in good faith shall be presumptive evidence of such amount. 2.14 Illegality; Impracticability. Notwithstanding any other provision contained in this Agreement, if: (a) it is unlawful, or any central bank or other governmental authority shall determine that it is unlawful, for the Bank to perform its obligations hereunder to make, continue, or convert Loans hereunder; or (b) on any date on which a Libor Rate would otherwise be set, the Bank shall have in good faith determined (which determination shall be conclusive absent manifest error) that (i) adequate and reasonable means do not exist for ascertaining a Libor Rate, (ii) a contingency has occurred which materially and adversely affects the interbank markets, or (iii) the effective cost to the Bank of funding a proposed Libor Rate Loan exceeds the Libor Rate then (y) on notice thereof by the Bank to the Borrowers, the obligation of the Bank to make or continue a Loan of a type so affected or to convert any type of Loan into a Loan of a type so affected shall terminate and the Bank shall thereafter be obligated to make Prime Rate Loans whenever any written notice requests any type of Loans so affected and (z) upon demand therefor by the Bank to the Borrowers, the Borrowers shall (i) forthwith prepay in full all Loans of the type so affected then outstanding, together with interest accrued thereon or (ii) request that the Bank, upon five (5) Business Days' notice, convert all Loans of the type so affected then outstanding into Loans of a type not so affected. If any such prepayment or conversion of any Libor Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in Section 2.13(c). 2.15 Payments. All payments to be made with respect to principal, interest, fees or other amounts due from the Borrowers under this Agreement or under the Notes are payable at 12:00 noon (Pittsburgh, Pennsylvania Time), on the day when due, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, and an action for the payments will accrue immediately. All such payments must be made to the Bank at its Office in U.S. Dollars and in funds immediately available at such Office, without setoff, counterclaim or other deduction of any nature. The Bank may in its discretion deduct such payments from the Borrowers' demand or deposit accounts with Bank if not paid within five (5) days after the due date. All such payments shall be applied at the option of the Bank to accrued and unpaid interest, outstanding principal and other sums due under this Agreement in such order as the Bank, in its sole discretion, shall elect. All such payments shall be made absolutely net of, without deduction or offset, and altogether free and clear of any and all present and future taxes, levies, deductions, charges, and withholdings and all liabilities with respect thereto, excluding income and franchise taxes imposed on the Bank under the laws of the United States or any state or political subdivision thereof. If the Borrowers are compelled by law to deduct any such taxes or levies (other than such excluded taxes) or to make any such other deductions, charges, or withholdings, they will pay such additional amounts as may be necessary in order that the net payments after such deduction, and after giving effect to any United States federal or state income taxes required to be paid by the Bank in respect of such additional amounts, shall equal the amount of such payment without such tax, deduction or withholding. 2.16 Loan Account. The Bank will open and maintain on its books a loan account (the "Loan Account") for the Borrowers with respect to Loans made, repayments, prepayments, the computation and payment of interest and fees and the computation and final payment of all other amounts due and sums paid to the Bank under this Agreement. The Loan Account for the Borrowers will be presumptive evidence as to the amount at any time due to the Bank from the Borrowers under this Agreement or the Notes. 2.17 Security. The Bank hereby releases, discharges and terminates all security interests, liens and other encumbrances created pursuant to the security documents listed on Schedule 2.17 to this Agreement (the "Prior Security Documents"), and such Prior Security Documents are hereby terminated and are of no further force and effect. Upon request of, and at the sole cost and expense of the Borrowers, the Bank will execute and deliver to the Borrowers such instruments as may be reasonably requested by the Borrowers to evidence the foregoing. Notwithstanding anything to the contrary contained in the preceding sentence, all indemnity and expense obligations contained in the Prior Security Documents, shall survive the termination of, and the release of the security interests and mortgages created under, the Prior Security Documents.
