The -16- Borrower shall have the right to borrow, repay and reborrow from the Lenders from the date hereof until the Revolving Credit Termination Date pursuant to draws upon the Revolving Credit the principal amount of which, together with the Stated Amount of all then outstanding Letters of Credit, shall not exceed $100,000,000 in the aggregate at any one time outstanding. 2.1b Commitment of Each Lender. Each Lender agrees, for itself only, and subject ------------------------- to the terms and conditions of this Agreement, to make Loans to the Borrower from time to time not to exceed an aggregate principal amount at any one time outstanding equal to the amount of its respective Commitment Percentage of the Revolving Credit. 2.1c Notes. The obligation of the Borrower to repay, on or before the Revolving ----- Credit Termination Date, the aggregate unpaid principal amount of all Loans shall be evidenced by the several Revolving Credit Notes, each substantially in the form of Exhibit "A" hereto, drawn by the Borrower to the order of a Lender ---------- in the maximum amount of such Lender's Commitment. The principal amount actually due and owing to a Lender at any time shall be the then aggregate unpaid principal amount of all Loans made by such Lender as shown on the Loan Account established and maintained by such Lender in accordance with Section 2.5. 2.1d Disbursements. The amount (i) of any Disbursement of a Base ------------- Rate Option shall be in the minimum aggregate principal amount of $1,000,000 or an integral multiple thereof and (ii) of any Disbursement to bear interest at the Euro-Rate Option shall be in the minimum aggregate principal amount of $2,000,000; provided, however that each incremental unit in excess of $2,000,000 -------- ------- shall be $1,000,000 or an integral multiple thereof. 2.1e Method of Making Disbursements. (i) Each request for Disbursements under ------------------------------ the Commitment shall be made by an Authorized Officer to the Administrative Agent orally or in writing (A) in the case of Disbursements to bear interest at the Base Rate Option, by 11:00 A.M. (eastern time) on the Borrowing Date, and (B) in the case of Disbursements to bear interest at the Euro-Rate Option, by 10:00 A.M.

No Lender's obligation to make a Disbursement shall be affected by any other Lender's failure to make funds available for the same or any other Disbursement. Nothing in this Subsection 2.1e shall be deemed to relieve any Lender from its obligation to fulfill its obligations to the Borrower under this Agreement or to prejudice any rights which the Borrower may have against any Lender as a result of any default by such Lender under this Agreement. 2.1f Voluntary Reductions of Commitment; Voluntary Principal Payments. ---------------------------------------------------------------- (i) Voluntary Reductions. Upon two Business Days' written notice to the -------------------- Administrative Agent, the Borrower may from time to time voluntarily permanently reduce the Commitment. Each voluntary reduction shall be in a minimum amount of $10,000,000 or, if greater than $10,000,000, in integral multiples of $1,000,000. (ii) Effect of Reductions. Simultaneously with each voluntary permanent -------------------- reduction, the Borrower shall make a payment of the outstanding Loans equal to the excess, if any, of (A) the aggregate principal amount of the outstanding Loans and the Stated Amount of any Letters of Credit over (B) the Commitment, as so reduced. Notice of a reduction, once given, shall be irrevocable. All such reductions shall be without penalty or premium (except for amounts owing pursuant to Subsection 2.2e, if any). (iii) Application of Reductions and Payments. Any principal payments shall be -------------------------------------- accompanied by all accrued and unpaid interest thereon, all amounts due pursuant to Section 2.2, if any, and, in the case of a permanent reduction of the Commitment to zero, any other outstanding Obligations which are then due and payable.

The Base Rate Option shall be adjusted from time to -------------------- time, without notice to the Borrower, as necessary to reflect any changes in the Base Rate, which adjustments shall be automatically effective on the day of any such change. (ii) Changes in the Applicable Euro-Rate Margin. On and after May 15, 1998, ------------------------------------------ the Applicable Euro-Rate Margin for each Euro-Rate Tranche then outstanding shall be -18- adjusted automatically, from time to time effective on (A) the forty- sixth day after the end of each of the first three Fiscal Quarters of each Fiscal Year and (B) the ninety-first day after the end of the fourth Fiscal Quarter of each Fiscal Year to reflect any change in the Borrower's Leverage Ratio. (iii) Changes in Euro-Rate Reserve Percentage. The Euro-Rate shall be adjusted --------------------------------------- from time to time, with respect to Euro-Rate Loans, without notice to the Borrower, as necessary to reflect any changes in the Euro-Rate Reserve Percentage, which adjustments shall be automatically effective on the day of such change. (iv) Event of Default.

(v) Notice of Changes. The Administrative Agent will promptly notify the ----------------- Borrower and the Lenders of any changes of rates set forth in items (i), (ii), (iii) and (iv) above which notice, in all cases, will be after such changes become effective.

Subject to the -------------------------------------------------------- remaining provisions of this Agreement, the Borrower shall have the option to elect to have all or any Loans bear interest at either of the Interest Rate Options and shall have the right to renew elections of Interest Rate Options and convert Loans to other Interest Rate Options. Notice of the Borrower's election shall be made in accordance with Section 2.1. Elections of, conversions to or renewals of the Base Rate Option shall continue in effect until converted to the Euro-Rate Option. Elections of, conversions to or renewals of the Euro-Rate Option shall expire as to each such Euro-Rate Option at the expiration of the applicable Euro-Rate Interest Period. Any Loans outstanding for which no elections have been made shall bear interest under the Base Rate Option. 2.2d Limitation on Election of Euro-Rate Options. Each election of the ------------------------------------------- Euro-Rate Option or the prepayment of all or any Euro-Rate Loans shall be in the minimum principal amount of $2,000,000 or, if in excess of $2,000,000, in integral multiples of $1,000,000. At no time during the term hereof may there be more than a total of seven (7) separate Euro-Rate Tranches in effect; provided, however, if the Borrower is borrowing under the Base Rate Option there - -------- ------- may be no more than a total of six (6) separate Euro-Rate Tranches in effect. Upon the occurrence and during the continuance of an Event of Default, the Borrower's right to elect, renew or convert to Euro-Rate Loans shall be suspended. -19- 2.2e Special Provisions Relating to Euro-Rate Option. ----------------------------------------------- (i) Euro-Rate Unascertainable. In the event that on any date on which a Euro- ------------------------- Rate would otherwise be set the Administrative Agent shall have determined in good faith (which determination shall be final and conclusive) that, by reason of circumstances affecting the London interbank market, adequate and reasonable means do not exist for ascertaining the Euro-Rate, the Administrative Agent shall give prompt notice of such determination to the Borrower and the Lenders and until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such determination no longer exist, the right of the Borrower to borrow under, renew or convert to the Euro-Rate Option shall be treated as a request to borrow under, renew or convert to the Base Rate Option. (ii) Illegality of Offering Euro-Rate. If a Lender shall determine in good -------------------------------- faith (which determination shall be final and conclusive) that compliance by such Lender with any applicable Governmental Rule (whether or not having the force of law), or the interpretation or application thereof by any Governmental Authority has made it unlawful for such Lender to make or maintain Euro-Rate Loans, such Lender shall give notice of such determination to the Borrower. Notwithstanding any provision of this Agreement to the contrary, unless and until such Lender shall give notice to the Borrower that the circumstances giving rise to such determination no longer apply: (A) with respect to any Euro-Rate Interest Periods thereafter commencing, interest on the corresponding Euro-Rate Loans (whichever one or more have been determined by the affected Lender to be unlawful) shall be computed and payable under the Base Rate Option; and (B) on such date, if any, as shall be required by law, any Euro-Rate Loans then outstanding shall be automatically renewed at the Base Rate Option; and the Borrower shall pay to the affected Lender the accrued and unpaid interest on such Euro-Rate Loans to (but not including) such renewal date. The Borrower shall pay the Administrative Agent any additional amounts reasonably necessary to compensate any Lender (on an after-tax basis) for any out-of-pocket costs incurred by such Lender as a result of any renewal pursuant to item (B) above on a day other than the last day of the relevant Euro-Rate Interest Period, including, but not limited to, any interest or fees payable by such Lender to lenders of funds obtained by them to loan or maintain the Loans so converted. Such Lender shall furnish to the Borrower a certificate showing the calculation of the amount necessary to compensate such Lender (on an after- tax basis) for such costs (which certificate, in the absence of manifest error, shall be conclusive), and the Borrower shall pay such amount to such Lender, as additional consideration hereunder, within ten (10) days of the Borrower's receipt of such certificate. (iii) Indemnity. In addition to the other provisions of this Section 2.2e, the --------- Borrower hereby agrees to indemnify each Lender against any loss or expense which such Lender may sustain or incur as a consequence of any default by the Borrower in failing to make any -20- borrowing, conversion or renewal hereunder to bear interest at the Euro-Rate Option on the scheduled date, in failing to make when due (whether by declaration, acceleration or otherwise) any payment of any Euro-Rate Loan or in making any payment or prepayment of any Euro-Rate Loan or any part thereof on any day other than the last day of the relevant Euro-Rate Interest Period, including but not limited to any loss of profit, premium or penalty incurred by each such Lender in respect of funds borrowed by it for the purpose of making or maintaining any Euro-Rate Loan as determined in good faith by each such Lender in the exercise of its sole but reasonable discretion. Each Lender shall furnish to the Borrower a certificate showing the calculation of the amount of any such loss or expense (which certificate, absent manifest error, shall be conclusive), and the Borrower shall pay such amount to each Lender within ten (10) days of the Borrower's receipt of such certificate. 2.2f Yield Protection. If any Governmental Rule or the interpretation or ---------------- application thereof by any court, any Governmental Authority charged with the administration thereof or the compliance with any guideline or request from any central bank or other Governmental Authority, whether or not having the force of law: (i) subjects any Lender to any tax, levy, impost, charge, fee, duty, deduction or withholding of any kind hereunder (other than any tax imposed or based upon the income of such Lender and payable to any Governmental Authority or taxing authority of the United States of America or any state thereof) or changes the basis of taxation of such Lender with respect to payments by the Borrower or principal, interest or other amounts due from the Borrower hereunder (other than any change which affects, and to the extent that it affects, the taxation by the United States of America or any state thereof of the total net income of such Lender); or (ii) imposes, modifies or deems applicable any reserve, special deposit, special assessment or similar requirements against assets held by, deposits with or for the account of or credit extended by any Lender with respect to loans to the Borrower (other than such requirements which are included in the determination of the Euro-Rate hereunder); or (iii) imposes upon any Lender any other condition with respect to this Agreement; and the result of any of the foregoing is to increase the cost to such Lender, reduce the income receivable by such Lender, reduce the rate of return on such Lender's capital or impose any expense upon such Lender by an amount which such Lender in its sole but reasonable discretion deems to be material, such Lender shall from time to time notify the Borrower and the Administrative Agent of the amount determined by such Lender (which determination, absent manifest error, shall be conclusive) to be reasonably necessary to compensate for such increase in cost, reduction in income, reduction in rate of return or additional expense, and setting forth the calculations therefor. The Borrower shall pay such amount to such Lender, as additional consideration hereunder, within ten (10) days of the Borrower' receipt of such notice from such Lender. -21- 2.2g Method of Calculation. In determining the amount due any Lender hereunder --------------------- by reason of the application of this Section 2.2, such Lender may use any reasonable averaging or attribution method; provided, however, that such Lender -------- ------- must use reasonable efforts to minimize such losses and costs. 2.2h Interest Payment Dates. Interest due on all outstanding Base Rate Loans ---------------------- shall be payable quarterly in arrears on the last day of each calendar quarter for the calendar quarter just ended, beginning on June 30, 1998. Interest due on all outstanding Euro-Rate Loans shall be payable on the last day of each Euro- Rate Interest Period and, for Euro-Rate Interest Periods of six months, also on the day which is three months after the first day of such Euro-Rate Interest Period. All accrued and unpaid interest on the Loans shall be due and payable on the Revolving Credit Termination Date. In addition, all accrued and unpaid interest on all of the Obligations shall be due and payable after any maturity of the Notes or the Obligations, whether by acceleration or otherwise, on demand until all amounts due hereunder are paid in full. 2.2i Calculation of Interest. Interest under the Base Rate Option shall be ----------------------- calculated on the basis of the actual number of days elapsed, using a year of 365 or 366 days, as the case may be. Interest under the Euro-Rate Option shall be calculated on the basis of the actual number of days elapsed, using a year of 360 days. Interest for any period shall be calculated from and including the first day thereof to but not including the last day thereof. 2.3 Letter of Credit Commitment. --------------------------- 2.3a Issuance of Letters of Credit. Subject to the further terms ----------------------------- and conditions of this Agreement and in reliance upon the representations and warranties set forth herein, the Issuing Bank agrees to issue upon the request of the Borrower to the Issuing Bank, Letters of Credit for the account of the Borrower or a Subsidiary of the Borrower in an aggregate Stated Amount not to exceed TEN MILLION DOLLARS ($10,000,000) at any one time outstanding (as may be increased or reduced and reinstated from time to time in accordance with the terms and provisions hereof). The Stated Amount of each Letter of Credit, while the same is issued and outstanding, shall be deducted from the maximum amount otherwise available under the Commitment. By way of illustration, if there are outstanding at any one time Letters of Credit having an aggregate Stated Amount of $5,000,000, the maximum availability under the Commitment, without accounting for reductions which are a function of voluntary permanent reductions, would be $95,000,000. No Letters of Credit may be issued hereunder to the extent the Stated Amount thereof together with the aggregate amount of Disbursements made under Subsection 2.1a, would exceed the maximum availability under the Commitment (as may be reduced pursuant to the terms of this Subsection 2.3a or Subsection 2.1f hereof). No Letter of Credit issued pursuant hereto shall have an initial term which exceeds twelve (12) months from the date of issuance (except the Existing Letters of Credit) nor have an expiration date later than fifteen (15) days prior to the Revolving Credit Termination Date. At least three (3) Business Days prior to the issuance of any Letter of Credit hereunder the Borrower shall complete and deliver to the Issuing Bank the Issuing Bank's then current form of Application for Letter of Credit. The issuance of each Letter of Credit in accordance with the provisions of this Subsection 2.3a shall require the satisfaction of each condition set forth in Sections 6.1 and 6.2 hereof. -22- 2.3b Limitation on Letters of Credit Commitment. In the event any ------------------------------------------ restrictions are imposed upon the Issuing Bank by any Governmental Rule of any Governmental Authority having jurisdiction over the banking activities of the Issuing Bank which would prevent the Issuing Bank from issuing a Letter of Credit or amending a Letter of Credit, the commitment of the Issuing Bank to issue the Letters of Credit or enter into any amendment with respect thereto shall be immediately suspended. The Issuing Bank shall promptly notify the Borrower of the existence and nature of any restriction which would cause the suspension of the commitment of the Issuing Bank to issue any Letter of Credit or to enter into amendments with respect thereto. The Borrower will thereupon undertake reasonable efforts to obtain the cancellation of the Letters of Credit; provided, however, that the refusal of any beneficiary of the Letters of -------- ------- Credit to surrender such Letters of Credit will not be an Event of Default hereunder and the Borrower shall undertake good faith efforts to obtain a substitute letter of credit or letters of credit for the Letters of Credit. Nothing contained in this Subsection 2.3b shall be deemed a termination of the Commitment and, in the event of a suspension of the commitment of the Issuing Bank to issue Letters of Credit as set forth above, the Borrower may continue to borrow under the Commitment provided the requirements of Article 6 hereof are complied with. 2.3c Request for Amendments to Letters of Credit. Whenever the Borrower desires ------------------------------------------- that the Issuing Bank enter into an amendment to a Letter of Credit, it shall deliver to the Administrative Agent and the Issuing Bank a written request no later than 11:00 a.m. (Pittsburgh, Pennsylvania time) at least three (3) Business Days in advance of the proposed date of such amendment. The Issuing Bank shall have no obligation to consent to any amendment to a Letter of Credit. Any such amendment which may be so consented to shall be effective only upon the satisfaction of the conditions set forth in Article 6 hereof. 2.3d Payment of Amounts Drawn Under Letters of Credit. Upon each request for a ------------------------------------------------ draw under a Letter of Credit by the beneficiary thereof, the Issuing Bank shall immediately notify the Borrower and the Administrative Agent and the Borrower shall reimburse, or cause the reimbursement of, the Issuing Bank on demand in an amount in same day funds equal to the amount of such draw; provided, however, -------- ------- that any failure of the Issuing Bank to notify the Borrower and the Administrative Agent prior to honoring any such draw shall not affect the Borrower's obligation to reimburse the Issuing Bank. Unless the Borrower shall have notified the Issuing Bank prior to such time that the Borrower intends to reimburse the Issuing Bank for all or a portion of the amount of such draw with funds other than the proceeds of Loans, the Borrower shall conclusively be deemed to have given a request for a Loan under Section 2.1 hereof to the Administrative Agent requesting the Lender to make Revolving Credit Loans at the Base Rate Option on the first Business Day immediately following the date on which such draw is honored in an aggregate amount equal to the excess of the amount of such draw over the amount theretofore received by the Issuing Bank in reimbursement thereof (the "Unreimbursed Amount"), plus accrued interest on such ---- amount at the rate set forth in Subsection 2.3e hereof. If the Borrower shall be deemed to have given a request for a Loan under Section 2.1 hereof to the Administrative Agent pursuant to this Subsection 2.3d, then, subject to satisfaction or waiver of the conditions specified in Section 6.1 hereof, the Lenders shall, on the first Business Day immediately following the date of such draw, make a Loan at the Base Rate Option in the aggregate amount of the -23- Unreimbursed Amount, plus accrued interest on such amount at the rate set forth ---- in Subsection 2.3e hereof. The proceeds of any such Loan shall be applied directly by the Issuing Bank, to reimburse the Issuing Bank for the Unreimbursed Amount, plus accrued interest on such amount. The foregoing shall not limit or impair the obligation of the Borrower to reimburse the Issuing Bank on demand for any Unreimbursed Amount. As to drafts or demands for payment under, or purporting to be under, a Letter of Credit which are payable in currency other than Dollars, (i) on each such draft, the equivalent of the amount paid at the rate of exchange then current in New York, New York for wire transfers to the place of payment in the currency in which such draft is drawn; and (ii) on each such demand for payment, the equivalent of the demand for payment at the rate of exchange then current in New York, New York for wire transfers to the place of payment in the currency in which the demand for payment is payable, on demand and in any event not later than the date for payment. If for any reason whatsoever, there exists at the time in question no rate of exchange generally current in New York, New York for wire transfers of such currency, the Borrower agrees to pay the Issuing Bank on demand in Dollars an amount equal to the actual cost of settlement of the Issuing Bank's obligation to the payor of the draft or demands for payment or any holder thereof, as the case may be, and however and whenever such settlement may be made by the Issuing Bank, including interest on the amount of United States of America currency payable by the Borrower at the rate provided in Subsection 2.3 from the date of payment of such draft or drawing to the date of the Borrower's payment to the Issuing Bank. 2.3e Letter of Credit Fees and Related Charges. ----------------------------------------- (i) Letter of Credit Fees. The Borrower agrees to pay (a) as to the Standby --------------------- Letters of Credit, in arrears to the Administrative Agent for the benefit of the Lenders, a fee per annum equal to the then current Applicable Euro-Rate Margin on the Stated Amount (or of any increase or decrease thereof) of each Letter of Credit, at the end of the first Fiscal Quarter after the issuance of each Letter of Credit and continuing quarterly thereafter during the term of each Letter of Credit or any subsequent amendment, renewal or extension thereof and at the expiration, surrender or final payment thereof and (b) as to commercial Letters of Credit, the Issuing Bank's then current standard fees for commercial Letters of Credit, which fees shall be paid in accordance with the Issuing Bank's then current practice for the payment of fees and costs relating to commercial Letters of Credit (collectively, "Letter of Credit Fees"). The foregoing notwithstanding, if any Event of Default shall have occurred and be continuing at the time of such issuance of any Letter of Credit or subsequent amendment, renewal or extension thereof, each Letter of Credit Fee payable thereafter during the continuation of such Event of Default shall be two hundred (200) basis points (2%) per annum above the fee otherwise in effect on the scheduled payment date. (ii) Fronting Fee.

(iii) Other Fees. With respect to the amendment or transfer of any Letter of ---------- Credit and each draw made thereunder, the Borrower shall pay, to the Issuing Bank for its own account, documentary and processing charges in accordance with the Issuing Bank's standard schedule for such charges in effect at the time of such amendment, transfer or draw, as the case may be.

The obligation of ------------------------------------------- the Borrower to reimburse the Issuing Bank for draws made under the Letters of Credit shall be absolute, unconditional and irrevocable and shall be paid directly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances: (i) any lack of validity or enforceability of the Letters of Credit; (ii) the existence of any claim, set-off, defense or other right which the Borrower may have at any time against a beneficiary or any transferee of the Letters of Credit (or any Persons for whom any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between the Borrower and the beneficiaries of the Letters of Credit); (iii) any draft, demand, certificate or any other document presented under the Letters of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; -25- (iv) payment by the Issuing Bank under a Letter of Credit against presentation of a demand, draft or certificate or other document which does not comply with the terms of such Letter of Credit except as the result of gross negligence or willful misconduct of the Issuing Bank; (v) any other circumstance or happening whatsoever, which is similar to any of the foregoing; and (vi) the fact that an Event of Default shall have occurred and be continuing. 2.3g Additional Payments. If by reason of (i) any change in any Governmental ------------------- Rule or any change in the interpretation or application by any judicial or regulatory authority of any Governmental Rule or (ii) compliance by the Issuing Bank with any direction, request or requirement (whether or not having the force of law) of any Governmental Authority: (i) the Issuing Bank shall be subject to any tax, levy, charge or withholding of any nature or to any variation thereof or to any penalty with respect to the maintenance or fulfillment of its obligations under this Section 2.3, whether directly or by such being imposed on or suffered by the Issuing Bank; (ii) any reserve, deposit or similar requirement is or shall be applicable, imposed or modified in respect of the Letters of Credit; (iii) there shall be imposed on the Issuing Bank any other condition regarding this Section 2.3 or the Letters of Credit; and if the result of any of the foregoing is to directly or indirectly increase the cost to the Issuing Bank of issuing or maintaining any Letter of Credit, or to reduce the amount receivable in respect thereof by, the Issuing Bank, then and in any such case the Issuing Bank may, at any time after the additional cost is incurred or the amount receivable is reduced, notify the Borrower and the Administrative Agent, and the Borrower shall pay on demand such amounts as the Issuing Bank may specify to be necessary to compensate the Issuing Bank for such additional cost or reduced receipt, together with interest on such amount from the date of the notice of such event which results in such increased cost or reduction in amount receivable until payment in full thereof at a rate equal at all times to the Base Rate. The determination by the Issuing Bank of any amount due pursuant to this Subsection 2.3g, as set forth in a certificate setting forth the calculation thereof, shall, in the absence of manifest error, be final and conclusive and binding on all of the parties hereto. 2.3h Indemnification; Nature of Duties. In addition to amounts payable as --------------------------------- elsewhere provided in this Section 2.3, the Borrower hereby agrees to protect, indemnify, pay and save the Administrative Agent or the Issuing Bank harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys' fees) which the Administrative Agent or the Issuing Bank may incur or be subject to as a consequence, direct or indirect, of (i) the issuance of the Letters of Credit or any amendment thereto, other than as a result of the gross negligence or willful misconduct of the Administrative Agent or the -26- Issuing Bank as determined by a court of competent jurisdiction, (ii) the failure of the Issuing Bank to honor a draw under any Letter of Credit if the Issuing Bank in good faith and upon advice of counsel believes that it is prohibited from making such payment as a result of any act or omission, any Governmental Authority, or (iii) any material breach by the Borrower of any representation, warranty, covenant, term or condition in, or the occurrence of any default under, any document related to the issuance or any amendment of the Letters of Credit. If any proceeding shall be brought or threatened against the Administrative Agent or the Issuing Bank by reason of or in connection with any event described in clauses (i) through (iii) above, the Administrative Agent shall promptly notify the Borrower in writing, and the Borrower shall assume the defense thereof, including the employment of counsel and payment of all costs of litigation. Notwithstanding the preceding sentence, the Administrative Agent and the Issuing Bank shall have the right to employ their own counsel and to determine its own defense of such action in any such case, but the fees and expenses of such counsel shall be at the expense of the Administrative Agent or the Issuing Bank, as the case may be, unless (x) the employment of such counsel shall have been authorized in writing by the Borrower, (y) the Borrower, after the aforementioned notice of the action, shall not have employed counsel to have charge of such defense or (z) if the position of the Borrower is adverse or contrary to the position advocated by the Administrative Agent or the Issuing Bank, as the case may be. In each case described in clauses (x), (y) and (z) immediately above the reasonable fees and expenses of counsel for the Administrative Agent or the Issuing Bank, as the case may be shall be borne by the Borrower. The Borrower shall not be liable for any settlement of any such action affected without its consent. The Issuing Bank is hereby expressly authorized and directed to honor any request for payment which is made under and in compliance with the terms of any Letter of Credit without regard to, and without any duty on the Issuing Bank's part to inquire into, the existence of any disputes or controversies between the Borrower or its Subsidiary, if applicable, the beneficiary of any Letter of Credit or any other Person, or the respective rights, duties or liabilities of any of them or whether any facts or occurrences represented in any of the documents presented under any Letter of Credit are true or correct. Furthermore, the Borrower fully understands and agrees that the Issuing Bank's sole obligation to the Borrower shall be limited to honoring requests for payment made under and in compliance with the terms of any Letter of Credit, the Application therefor and this Agreement and the Issuing Bank's obligation remains so limited even if the Issuing Bank may have assisted the Borrower in the preparation of the wording of any Letter of Credit or any documents required to be presented thereunder or that the Issuing Bank may otherwise be aware of the underlying transaction giving rise to any Letter of Credit and this Agreement. As between the Borrower and the Issuing Bank, the Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the beneficiaries of the Letters of Credit. In furtherance and not in limitation of the foregoing, the Issuing Bank shall not be responsible: (i) for the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for or the issuance or amendment of the Letters of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the validity or sufficiency of any -27- instrument transferring or assigning or purporting to transfer or assign the Letters of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) for failure of a beneficiary of a Letter of Credit to comply fully with conditions required in order to draw upon such Letter of Credit; (iv) for errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telecopy, telex or otherwise, whether or not they be in cipher; (v) for errors in interpretation of technical terms; (vi) for any loss or delay in the transmission or otherwise of any document required in order to make a draw under the Letters of Credit or of the proceeds thereof; (vii) for the misapplication by a beneficiary of any Letter of Credit of the proceeds of any drawing under such Letter of Credit; (viii) for any consequences arising from causes beyond the control of the Issuing Bank, including, without limitation, any Government Rules; and (ix) for any other circumstances whatsoever in making or failing to make payment under a Letter of Credit; except that the Borrower or its Subsidiary, if applicable, shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower or its Subsidiary, if applicable, as determined by a court of competent jurisdiction to be the result of (i) the Issuing Bank's willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of the Letter of Credit, (ii) the Issuing Bank's willful misconduct or gross negligence in paying a draw under a Letter of Credit to any Person other than the beneficiary of such Letter of Credit or its lawful successor, representative or assign (or as otherwise directed in writing by the beneficiary of such Letter of Credit) or (iii) the Issuing Bank's willful failure to pay under a Letter of Credit after the presentation to it by the beneficiary of such Letter of Credit or its lawful successor, representative or assign of a sight draft and certificate or other documents strictly complying with the terms and conditions of such Letter of Credit, unless the Issuing Bank in good faith and upon advice of counsel believes that it is prohibited by law or other legal authority from making such payment. None of the above shall affect, impair, or prevent the vesting of any of the Issuing Bank's rights or powers hereunder. Except for the Issuing Bank's obligations to issue Letters of Credit hereunder and its obligations under such Letters of Credit, the Issuing Bank shall have no liability to the Borrower from a reduction of the Issuing Bank's credit rating or any deterioration in its financial condition. The Borrower shall bear and pay all reasonable expenses of every kind (including all reasonable attorneys' fees) of the enforcement of any of the Issuing Bank's rights under this Agreement or the Letters of Credit, or of any claim or demand by the Issuing Bank against the Borrower, or of any actual or attempted sale, exchange, enforcement, collection, maintenance, retention, insurance, compromise, settlement, release, delivery on trust receipt, or other security agreement, or delivery of any such security, and of the receipt of proceeds thereof, and will repay to the Issuing Bank any such expenses incurred by the Issuing Bank. In furtherance and extension and not in limitation of the specific provisions hereinabove set forth, any action taken or omitted by the Issuing Bank under or in connection with the Letters of Credit or the related sight drafts or certificates or documents, if taken or omitted in good faith, shall not put the Issuing Bank under any resulting liability to the Borrower. -28- Whenever appropriate to prevent unjust enrichment and to the end that the Borrower shall bear substantially all of the risks relative to any Letter of Credit and the underlying transactions, the Issuing Bank shall be subrogated (for purposes of defending against the Borrower's or its Subsidiary's claims and proceeding against others to the extent of the Issuing Bank's liability to the Borrower or its Subsidiary) to the Borrower's or its Subsidiary's rights against any person, firm or entity who may be liable to the Borrower or its Subsidiary on any underlying transaction, to the rights of any holder in due course or person with similar status against the Borrower or its Subsidiary, and to the rights of the beneficiary or its assignee or person with similar status against the Borrower or its Subsidiary. 2.3i Construction of Applications and Agreement for Letter of Credit. This --------------------------------------------------------------- Agreement is intended to supplement the Applications for Letter of Credit, executed by the Borrower and delivered to the Issuing Bank. Whenever possible, this Agreement is to be construed as consistent with said Applications for Letter of Credit and to the extent that the provisions of this Agreement and said Applications for Letter of Credit conflict the terms of this Agreement shall control. 2.3j Uniform Customs.

The Issuing Bank hereby sells, and each ------------------ Lender hereby purchases, on a continuing basis, a participation and an undivided interest in (i) the obligations of the Issuing Bank to honor any drawing under any Letter of Credit and (ii) the Indebtedness of the Borrower to the Issuing Bank under this Agreement in respect of each Letter of Credit, such participation being in the amount of such Lender's Commitment Percentage of such obligations and Indebtedness. 2.4 Method of Payments. All payments of principal, interest, Fees, costs and ------------------ other amounts due hereunder and under the other Loan Documents shall be made by the Borrower to the Administrative Agent at the Administrative Agent's principal office at One PNC Plaza, 249 Fifth Avenue, Pittsburgh Pennsylvania 15222 not later than 2:00 p.m. (Eastern time) on the due date.

Each Lender shall open and maintain on its ------------ books a Loan Account in the Borrower's name with respect to Loans made, repayments, prepayments, the computation and payment of interest and other amounts due and sums paid to such Lender hereunder and under the other Loan Documents. Except in the case of manifest error in -29- computation, such records shall be conclusive and binding on the Borrower as to the amount at any time due to the Lender by the Borrower. 2.6 Payment From Accounts Maintained by Borrower. For ease of administration, in -------------------------------------------- the event that any payment of principal, interest, Fees, other expenses or amounts due the Lenders, the Issuing Bank or the Agents under any of the Loan Documents is not paid when due, the Administrative Agent is hereby authorized to effect such payment by debiting any demand deposit account of the Borrower now or in the future maintained with PNC Bank other than accounts maintained in trust for the benefit of third parties. This right to debit accounts of the Borrower is in addition to any right of setoff accorded the Lenders hereunder or by operation of law. 2.7 Commitment Fee. Beginning on June 30, 1998, and continuing on the last day -------------- of each calendar quarter thereafter until the Revolving Credit Termination Date and on the Revolving Credit Termination Date, the Borrower shall pay a Commitment Fee to the Administrative Agent for the benefit of the Lenders, in arrears, at the Applicable Commitment Fee on the average daily unused portion of the Commitment during the calendar quarter or period then ended.

The Commitment Fee shall be calculated from the Closing Date. The Applicable Commitment Fee shall be adjusted as appropriate on the forty-sixth day after the end of each of the first three Fiscal Quarters of each Fiscal Year and on the ninety-first day after the end of each Fiscal Year to reflect any change in the Borrower's Leverage Ratio. 2.8 Capital Adequacy.
