2. REVOLVING CREDIT AND SWING LOAN FACILITIES

2.1 Revolving Credit Loans and Swing Loans.

2.1.1. Revolving Credit Loans.

Subject to the terms and conditions hereof and relying upon the representations and warranties herein set forth, each Lender severally agrees to make Revolving Credit Loans to the Borrower at any time or from time to time on or after the date hereof to the Expiration Date provided that after giving effect to such Loan the aggregate amount of Revolving Credit Loans from such Lender shall not exceed such Lender’s Revolving Credit Commitment minus such

Lender’s (i) Ratable Share of the Letters of Credit Outstanding, and (ii) Ratable Share of the Swing Loans outstanding. Within such limits of time and amount and subject to the other provisions of this Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section 2.1.1.

2.1.2. Swing Loans.

Subject to the terms and conditions hereof and relying upon the representations and warranties herein set forth, PNC Bank may, at its option, cancelable at any time for any reason whatsoever, make overnight swing loans (the “Swing Loans”) to the Borrower at any time or from time to time after the date hereof to, but not including, the Expiration Date, in an aggregate principal amount up to but not in excess of the Swing Loan Commitment, provided that the aggregate principal amount of PNC Bank’s Swing Loans and the Revolving Credit Loans of all the Lenders at any one time outstanding plus the amount of the Letters of Credit Outstanding shall not exceed the Revolving Credit Commitments of all the Lenders. Within such limits of time and amount and subject to the other provisions of this Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section 2.1.2.

2.1.3. Restatement of Commitments.

This Agreement amends and restates the Existing Credit Agreement. The commitments of the Lenders under this Agreement replace the commitments of the lenders under the Existing Credit Agreement. From and after the Closing Date, the commitments of the lenders under the Existing Credit Agreement no longer constitute a separate obligation of such lenders, and the Borrower hereby terminates commitments of lenders under the Existing Credit Agreement which are not parties to this Agreement.

2.2 Nature of Lenders’ Obligations with Respect to Revolving Credit Loans.

Each Lender shall be obligated to participate in each request for Revolving Credit Loans pursuant to Section 2.5 [Revolving Credit Loan Requests] in accordance with its Ratable Share. The aggregate of each Lender’s Revolving Credit Loans outstanding hereunder to the Borrower at any time shall never exceed its Revolving Credit Commitment minus its Ratable Share of the amount of Letters of Credit Outstanding. The obligations of each Lender hereunder are several. The failure of any Lender to perform its obligations hereunder shall not affect the Obligations of the Borrower to any other party nor shall any other party be liable for the failure of such Lender to perform its obligations hereunder. The Lenders shall have no obligation to make Revolving Credit Loans hereunder on or after the Expiration Date.

2.3 Commitment Fees.

Accruing from the date hereof until the Expiration Date, the Borrower agrees to pay to the Administrative Agent for the account of each Lender, as consideration for such Lender’s Revolving Credit Commitment hereunder, a nonrefundable commitment fee equal to a rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) on the average daily difference between the amount of (i) such Lender’s

Revolving Credit Commitment as the same may be constituted from time to time (for purposes of this computation, PNC Bank’s Swing Loans shall be deemed to be borrowed amounts under its Revolving Credit Commitment) and the (ii) the sum of such Lender’s Revolving Credit Loans outstanding plus its Ratable Share of Letters of Credit Outstanding. During such time as any of the 2003 Senior Notes remain outstanding, the rate per annum for the commitment fee shall be based upon the average Revolving Facility Usage during the applicable period as follows:


Revolving Facility Usage as a Percentage of Revolving Credit Commitments	Commitment Fee Rate per Annum
Less than 25%	0.750	%

Equal to or greater than 25% but less than 50%	0.500	%

Equal to or greater than 50%	0.375	%

At such time as all 2003 Senior Notes have been redeemed by the Borrower, the rate per annum for the commitment fee shall be 0.375% at all times. All such Commitment Fees shall be payable in arrears on the first day of each November, February, May and August after the date hereof and on the Expiration Date or upon acceleration of the Notes.

2.4 Reduction of Revolving Credit Commitment.

The Borrower shall have the right at any time and from time to time upon five (5) Business Days’ prior written notice to the Administrative Agent to permanently reduce, in whole multiples of $1,000,000 of principal, or terminate the Revolving Credit Commitment without penalty or premium, except as hereinafter set forth, provided that any such reduction or termination shall be accompanied by (a) the payment in full of any Commitment Fees then accrued on the amount of such reduction or termination and (b) prepayment of the Revolving Credit Notes, together with the full amount of interest accrued on the principal sum to be prepaid (and all amounts referred to in Section 5.6 hereof), to the extent that the aggregate amount thereof then outstanding exceeds the Revolving Credit Commitment as so reduced or terminated. From the effective date of any such reduction or termination the obligations of Borrower to pay the Commitment Fee pursuant to Section 2.3 shall correspondingly be reduced or cease.

2.5 Revolving Credit Loan Requests; Swing Loan Requests.

2.5.1. Revolving Credit Loan Requests.

Except as otherwise provided herein, the Borrower may from time to time prior to the Expiration Date request the Lenders to make Revolving Credit Loans, or renew or convert the Interest Rate Option applicable to existing Revolving Credit Loans pursuant to Section 4.2 [Interest Periods], by delivering to the Administrative Agent, not later than 12:00 noon, Pittsburgh time, (i) three (3) Business Days prior to the proposed Borrowing Date with respect to

the making of Revolving Credit Loans to which the Euro-Rate Option applies or the conversion to or the renewal of the Euro-Rate Option for any such Loans; and (ii) on either the proposed Borrowing Date with respect to the making of a Revolving Credit Loan to which the Base Rate Option applies or the last day of the preceding Interest Period with respect to the conversion to the Base Rate Option for any such Loan, of a duly completed request therefor substantially in the form of Exhibit 2.5.1 or a request by telephone immediately confirmed in writing by letter, facsimile or telex in such form (each, a “Loan Request”), it being understood that the Administrative Agent may rely on the authority of any individual making such a telephonic request without the necessity of receipt of such written confirmation. Each such Loan Request shall be irrevocable and shall specify (i) the proposed Borrowing Date; (ii) the aggregate amount of the proposed Loans comprising each Borrowing Tranche, which shall be in integral multiples of $500,000 and not less than $1,000,000 for each Borrowing Tranche to which the Euro-Rate Option applies and not less than the lesser of $100,000 or the maximum amount available for Borrowing Tranches to which the Base Rate Option applies; (iii) whether the Euro-Rate Option or Base Rate Option shall apply to the proposed Loans comprising the applicable Borrowing Tranche; and (iv) in the case of a Borrowing Tranche to which the Euro-Rate Option applies, an appropriate Interest Period for the Loans comprising such Borrowing Tranche.

2.5.2. Swing Loan Requests.

Except as otherwise provided herein, the Borrower may from time to time prior to the Expiration Date request PNC Bank to make Swing Loans by delivery to PNC Bank not later than 11:00 a.m., Pittsburgh time, on the proposed Borrowing Date of a duly completed request therefor substantially in the form of Exhibit 2.5.2 hereto or a request by telephone immediately confirmed in writing by letter, facsimile or telex (each, a “Swing Loan Request”), it being understood that the Administrative Agent may rely on the authority of any individual making such a telephonic request without the necessity of receipt of such written confirmation. Each Swing Loan Request shall be irrevocable and shall specify the proposed Borrowing Date and the principal amount of such Swing Loan, which shall be in integral multiples of $100,000 and not less than $500,000.

2.6 Making Revolving Credit Loans and Swing Loans.

2.6.1. Making Revolving Credit Loans

The Administrative Agent shall, promptly after receipt by it of a Loan Request pursuant to Section 2.5.1 [Revolving Credit Loan Requests], notify the Lenders of its receipt of such Loan Request specifying: (i) the proposed Borrowing Date and the time and method of disbursement of the Revolving Credit Loans requested thereby; (ii) the amount and type of each such Revolving Credit Loan and the applicable Interest Period (if any); and (iii) the apportionment among the Lenders of such Revolving Credit Loans as determined by the Administrative Agent in accordance with Section 2.2 [Nature of Lenders’ Obligations]. Each Lender shall remit the principal amount of each Revolving Credit Loan to the Administrative Agent such that the Administrative Agent is able to, and the Administrative Agent shall, to the extent the Lenders have made funds available to it for such purpose and subject to Section 7.2 [Each Additional Loan], fund such Revolving Credit Loans to the Borrower in U.S. Dollars and

immediately available funds at the Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable Borrowing Date, provided that if any Lender fails to remit such funds to the Administrative Agent in a timely manner, the Administrative Agent may elect in its sole discretion to fund with its own funds the Revolving Credit Loans of such Lender on such Borrowing Date, and such Lender shall be subject to the repayment obligation in Section 10.16 [Availability of Funds].

2.6.2. Making Swing Loans.

So long as PNC Bank elects to make Swing Loans, PNC Bank shall, after receipt by it of a Swing Loan Request pursuant to Section 2.5.2, fund such Swing Loan to the Borrower in U.S. Dollars and immediately available funds at the Principal Office prior to 2:00 p.m., Pittsburgh time, on the Borrowing Date.

2.7.2. Swing Loan Notes.

The Obligation of the Borrower to repay the unpaid principal amount of the Swing Loans made to it by PNC Bank together with interest thereon shall be evidenced by a demand promissory note of the Borrower dated the Closing Date in substantially the form attached hereto as Exhibit 1.1(N)(2) payable to the order of PNC Bank, the aggregate face amount of which notes equals the Swing Loan Commitment.

2.8 Use of Proceeds.

The proceeds of the Revolving Credit Loans may be used (i) to refinance Indebtedness of the Borrower under the Existing Credit Agreement, (ii) to finance the redemption of the 2003 Senior Notes of the Borrower in accordance with the terms of the 2003 Senior Note Indenture, (iii) to provide working capital to the Borrower, (iv) for general corporate purposes of the Borrower, including advances to Subsidiaries permitted under this Agreement, dividends and distributions permitted under Section 8.2.5 [Restricted Payments] and transaction costs and expenses, and (v) in accordance with Section 8.1.10 [Use of Proceeds].

2.9 Borrowings to Repay Swing Loans.

2.10 Letter of Credit Subfacility.

2.10.1. Issuance of Letters of Credit.

The Borrower may request the issuance of a letter of credit (each a “Letter of Credit”) on behalf of itself or another Guarantor or on behalf of the Borrower and a Subsidiary of the Borrower which is not a Guarantor (in which case the Borrower and such Subsidiary shall be co-applicants with respect to such Letter of Credit) by delivering or having such other Loan Party deliver to the Administrative Agent a completed application and agreement for letters of credit in such form as the Administrative Agent may specify from time to time by no later than 10:00 a.m., Pittsburgh time, at least five (5) Business Days, or such shorter period as may be agreed to by the Administrative Agent, in advance of the proposed date of issuance. Each Letter of Credit shall be a Standby Letter of Credit or a Commercial Letter of Credit and shall be denominated in either Dollars or an Optional Currency. Subject to the terms and conditions hereof and in reliance on the agreements of the other Lenders set forth in this Section 2.10, the Administrative Agent (and, upon request of the Borrower, consent of the Administrative Agent, and consent of the requested Issuing Bank, any other Issuing Bank designated by the Administrative Agent in accordance with the terms of this Section) will issue a Letter of Credit provided that each Letter of Credit shall (A) have a maximum maturity of twelve (12) months from the date of issuance (but may include a provision for the automatic extension of the Letter of Credit absent notice by the Issuing Bank to the beneficiary), and (B) in no event expire later than ten (10) Business Days prior to the Expiration Date, and provided that in no event shall (i) the Dollar Equivalent amount of Letters of Credit Outstanding exceed, at any one time, $35,000,000, or (ii) the Revolving Facility Usage exceed, at any one time, the Revolving Credit Commitments. From time to time the Borrower may request that a Lender other than the Administrative Agent issue Letters of Credit on its behalf (or on behalf of another Guarantor) hereunder by submitting a written request to such effect to the Administrative Agent, which request the Administrative Agent shall forward to the requested Lender; in the event that such requested Lender consents thereto, and subject to the consent of the Administrative Agent, the Administrative Agent shall be permitted to designate one or more of such additional Lenders as “Issuing Banks” hereunder. Those letters of credit issued by the Administrative Agent described on Schedule 2.10 shall from and after the Closing Date be deemed to be Letters of Credit issued pursuant to the terms of this Section 2.10.1.

2.10.2. Letter of Credit Fees.

The Borrower shall pay in Dollars (i) to the Administrative Agent for the ratable account of the Lenders a fee (the “Letter of Credit Fee”) equal to the Applicable Letter of Credit Fee then in effect (computed on the basis of a year of 360 days and actual days elapsed) per annum, and (ii) to each Issuing Bank (including the Administrative Agent) for its own account a fronting fee equal to .250% per annum (computed on the basis of a year of 360 days and actual days elapsed), which fees shall be computed on the daily average amount of Letters of Credit Outstanding issued by such Issuing Bank and shall be payable quarterly in arrears commencing with the first day of each November, February, May and August following issuance of each Letter of Credit and on the Expiration Date. The Borrower shall also pay to each Issuing Bank (including the Administrative Agent) in Dollars for its own account such Issuing Bank’s then in effect customary fees and administrative expenses payable with respect to the Letters of Credit as such Issuing Bank may generally charge or incur from time to time in connection with the issuance, maintenance, modification (if any), assignment or transfer (if any), negotiation, and administration of Letters of Credit.

2.10.3. Disbursements, Reimbursement.

2.10.3.1. Immediately upon the Issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from each Issuing Bank a participation in such Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Ratable Share of the maximum amount available to be drawn under such Letter of Credit and the amount of such drawing, respectively.

2.10.3.2. In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, the relevant Issuing Bank will promptly notify the Administrative Agent and the Borrower. Provided that it shall have received such notice, the Borrower shall reimburse (such obligation to reimburse such Issuing Bank sometimes be referred to as a “Reimbursement Obligation”) such Issuing Bank in Dollars prior to 12:00 noon, Pittsburgh time on each date that an amount is paid by such Issuing Bank under any Letter of Credit (each such date, a “Drawing Date”) in an amount equal to the amount so paid by such Issuing Bank. In the event the Borrower fails to reimburse such Issuing Bank for the full amount of any drawing under any Letter of Credit by 12:00 noon, Pittsburgh time, on the Drawing Date, such Issuing Bank will promptly notify the Administrative Agent, which will in turn promptly notify each Lender thereof, and the Borrower shall be deemed to have requested that Revolving Credit Loans be made by the Lenders in Dollars under the Base Rate Option to be disbursed on the Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the Revolving Credit Commitment and subject to the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice requirements. Any notice given by such Issuing Bank or the Administrative Agent pursuant to this Section 2.10.3.2 may be oral if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

2.10.3.3. Each Lender shall upon any notice pursuant to Section 2.10.3.2 make available to the Administrative Agent for the account of the relevant

Issuing Bank an amount in Dollars in immediately available funds equal to its Ratable Share of the amount of the drawing, whereupon the participating Lenders shall (subject to Section 2.10.3.4) each be deemed to have made a Revolving Credit Loan in Dollars under the Base Rate Option to the Borrower in that amount. If any Lender so notified fails to make available in Dollars to the Administrative Agent for the account of the relevant Issuing Bank the amount of such Lender’s Ratable Share of such amount by no later than 2:00 p.m., Pittsburgh time on the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the Drawing Date to the date on which such Lender makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Revolving Credit Loans under the Base Rate Option on and after the fourth day following the Drawing Date. The relevant Issuing Bank and, in turn, the Administrative Agent will promptly give notice of the occurrence of the Drawing Date, but failure of the Issuing Bank or the Administrative Agent to give any such notice on the Drawing Date or in sufficient time to enable any Lender to effect such payment on such date shall not relieve such Lender from its obligation under this Section 2.10.3.3.

2.10.3.4. With respect to any unreimbursed drawing that is not converted into Revolving Credit Loans under the Base Rate Option to the Borrower in whole or in part as contemplated by Section 2.10.3.2, because of the Borrower’s failure to satisfy the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice requirements or for any other reason, the Borrower shall be deemed to have incurred from the relevant Issuing Bank a borrowing (each a “Letter of Credit Borrowing”) in Dollars in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate per annum applicable to the Revolving Credit Loans under the Base Rate Option. Each Lender’s payment to the Administrative Agent pursuant to Section 2.10.3.3 shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Lender in satisfaction of its participation obligation under this Section 2.10.3.

2.10.4. Repayment of Participation Advances.

2.10.4.1. Upon (and only upon) receipt by the relevant Issuing Bank for its account of immediately available funds from the Borrower (i) in reimbursement of any payment made by such Issuing Bank under the Letter of Credit with respect to which any Lender has made a Participation Advance to the Administrative Agent, or (ii) in payment of interest on such a payment made by such Issuing Bank under such a Letter of Credit, such Issuing Bank will pay to each Lender, in the same funds as those received by such Issuing Bank, the amount of such Lender’s Ratable Share of such funds, except such Issuing Bank shall retain the amount of the Ratable Share of such funds of any Lender that did not make a Participation Advance in respect of such payment by such Issuing Bank.

2.10.4.2. If any Issuing Bank or the Administrative Agent is required at any time to return to the Borrower of any Guarantor, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the payments made by any such Loan Party to such Issuing Bank or the Administrative Agent pursuant to

Section 2.10.4.1 in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Lender shall, on demand of the Administrative Agent, forthwith return to the Administrative Agent the amount of its Ratable Share of any amounts so returned by such Issuing Bank or the Administrative Agent plus interest thereon from the date such demand is made to the date such amounts are returned by such Lender to the Administrative Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time.

2.10.5. Documentation.

Each Loan Party agrees to be bound by the terms of each Issuing Bank’s (including the Administrative Agent’s) application and agreement for letters of credit and each Issuing Bank’s (including the Administrative Agent’s) written regulations and customary practices relating to letters of credit, though such interpretation may be different from such Loan Party’s own. In the event of a conflict between such application or agreement and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct and in the case of a violation of Section 2.10.6 by the Issuing Bank in a material manner, each Issuing Bank shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following any Loan Party’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

2.10.6. Determinations to Honor Drawing Requests.

In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, each Issuing Bank shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit.

2.10.7. Nature of Participation and Reimbursement Obligations for Letters of Credit.

Each Lender’s obligation in accordance with this Agreement to make the Revolving Credit Loans or Participation Advances, as contemplated by Section 2.10.3, as a result of a drawing under a Letter of Credit, and the Obligations of the Borrower to reimburse each Issuing Bank upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.10 under all circumstances, including the following circumstances:

(iii) any lack of validity or enforceability of any Letter of Credit;

(iv) any claim of breach of warranty that might be made by any Loan Party or any Lender against any beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense or other right which any Loan Party or any Lender may have at any time against a beneficiary, successor beneficiary any transferee or assignee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), such Issuing Bank or the Administrative Agent or their Affiliates or any Lender or any other Person or, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Loan Party or Subsidiaries of a Loan Party and the beneficiary for which any Letter of Credit was procured);

(v) the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit, or the transport of any property or provisions of services relating to a Letter of Credit, in each case even if such Issuing Bank or the Administrative Agent or any of their Affiliates has been notified thereof;

(vi) payment by such Issuing Bank or the Administrative Agent or any of their Affiliates under any 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;

2.10.8. Indemnity.

In addition to amounts payable as provided in Section 10.5 [Reimbursement of Administrative Agent by Borrower, Etc.], the Borrower hereby agrees to protect, indemnify, pay and save harmless each Issuing Bank and any of its Affiliates that has issued a Letter of Credit from and against any and all claims, demands, liabilities, damages, taxes, penalties, interest, judgments, losses, costs, charges and expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of internal counsel) which such Issuing Bank or any of its Affiliates may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit, other than as a result of (A) the gross negligence or willful misconduct of such Issuing Bank as determined by a final judgment of a court of competent jurisdiction, (B) failure by such Issuing Bank to comply with Section 2.10.6 in a material manner, or (C) the wrongful dishonor by such Issuing Bank or any of its Affiliates of a proper demand for payment made under any Letter of Credit, except if such dishonor resulted from any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority (all such acts or omissions herein called “Governmental Acts”).

2.10.9. Liability for Acts and Omissions.

As between any Loan Party and each Issuing Bank, or its Affiliates, such Loan Party assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, each Issuing Bank shall not be responsible for any of the following including any losses or damages to any Loan Party or other Person or property relating therefrom: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if such Issuing Bank or its Affiliates shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter 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) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Loan Party against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Loan Party and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of such Issuing Bank or its Affiliates, as applicable, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of such Issuing Bank’s or its Affiliates rights or powers hereunder. Nothing in the preceding sentence shall relieve any Issuing Bank from liability for such Issuing Bank’s gross negligence or willful misconduct in connection with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall any Issuing Bank or its Affiliates be liable to any Loan Party for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.

Without limiting the generality of the foregoing, each Issuing Bank and the Administrative Agent and their Affiliates (i) may rely on any oral or other communication believed in good faith by such Issuing Bank, the Administrative Agent or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by such Issuing Bank or its Affiliate; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on such Issuing Bank or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document and honor any drawing in connection with any Letter of Credit that is the subject to such order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.

In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by any Issuing Bank, the Administrative Agent or their Affiliates under or in connection with the Letters of Credit issued by it or any

documents and certificates delivered thereunder, if taken or omitted in good faith, shall not put such Issuing Bank, the Administrative Agent or their Affiliates under any resulting liability to the Borrower or any Lender.

2.11 Periodic Computations of Dollar Equivalent Amounts of Letters of Credit Outstanding.

The Administrative Agent will determine the Dollar Equivalent amount of (i) proposed Letters of Credit to be denominated in any Optional Currency as of the requested date of issuance, and (ii) Letters of Credit Outstanding denominated in the Optional Currencies as of the last Business Day of each month, (each such date under clauses (i) and (ii), a “Computation Date”). If on any Computation Date the Revolving Facility Usage is greater than the Revolving Credit Commitments as a result of a change in exchange rates between the Optional Currency and Dollars, then the Administrative Agent shall notify the Borrower of the same. The Borrower shall pay the Loans (subject to Borrower’s indemnity obligations under Section 5.6 hereof) within one (1) Business Day after receiving such notice such that the Revolving Facility Usage shall not exceed the Revolving Credit Commitments after giving effect to such payments.

2.12 Additional Revolving Credit Commitments.

Subject to the terms and conditions set forth herein, the Borrower may at any time, but not more often than two (2) times during the term of this Agreement, request an increase in the Revolving Credit Commitment (the “Additional Revolving Credit Commitment”) provided that (a) immediately prior to and after giving effect to such Additional Revolving Credit Commitment (and the making of any loans pursuant thereto), no Event of Default or Potential Default has occurred or is continuing or shall result therefrom and, (b) the Additional Revolving Credit Commitment shall rank pari passu in right of payment and right of security in respect of the Collateral with the existing Revolving Credit Loans, (c) the Additional Revolving Credit Commitments shall not exceed in the aggregate Fifty Million and 00/100 Dollars ($50,000,000.00), and (d) the loans to be made pursuant to such Additional Revolving Credit Commitment shall have the same terms as the Revolving Credit Loans. Any additional bank, financial institution, existing Lender or other Person that elects to extend commitments to provide the Additional Revolving Credit Commitment shall be reasonably satisfactory to the Borrower and the Administrative Agent (any such bank, financial institution, existing Lender or other person is an “Additional Lender”) and shall become a Lender under this Agreement pursuant to an amendment (the “Incremental Facility Amendment”) to this Agreement, and, as appropriate, the other Loan Documents, executed by the Loan Parties, each Additional Lender, if any, and the Administrative Agent. Commitments in respect of the Additional Revolving Credit Commitment shall become Commitments under this Agreement after giving effect to such Additional Revolving Credit Commitment. The Incremental Facility Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be reasonably necessary or appropriate to effectuate the applicable additional Revolving Credit Commitments in the opinion of the Administrative Agent. The effectiveness of any Incremental Facility Amendment shall be subject to the satisfaction on the date thereof (the “Incremental Facility Closing Date”) of each of the applicable conditions set forth in Article 7

[Conditions of Lending and Issuance of Letters of Credit] (it being understood that all references to the Closing Date in such Article 7 [Conditions of Lending and Issuance of Letters of Credit] shall be deemed to refer to the Incremental Facility Closing Date), and except as otherwise specified in the Incremental Facility Amendment, the Administrative Agent shall have received legal opinions, board resolutions and other closing documents and certificates reasonably requested by the Administrative Agent and consistent with those delivered on the Closing Date under Article 7 [Conditions of Lending and Issuance of Letters of Credit]. The proceeds of the Additional Revolving Credit Commitment may be used in accordance with Section 2.8 [Use of Proceeds] but not for any purpose otherwise prohibited hereunder. Notwithstanding anything to the contrary in this Section 2.11 [Additional Revolving Credit Commitment], no existing Lender shall be obligated to provide Additional Revolving Credit Commitment.

3. [INTENTIONALLY OMITTED].

4. INTEREST RATES

4.1 Interest Rate Options.

The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the Loans as set forth below applicable to the respective Loans, it being understood that, subject to the provisions of this Agreement, the Borrower may select different Interest Rate Options and Borrower may select different Interest Periods to apply simultaneously to the Loans comprising different Borrowing Tranches and may convert to or renew one or more Interest Rate Options with respect to all or any portion of the Loans comprising any Borrowing Tranche, provided that there shall not be at any one time outstanding more than twelve (12) Borrowing Tranches in the aggregate among all of the Loans, and provided further that only the As-Offered Rate shall apply to the Swing Loans. If at any time the designated rate applicable to any Loan made by any Lender exceeds such Lender’s highest lawful rate, the rate of interest on such Lender’s Loan shall be limited to such Lender’s highest lawful rate.

4.1.1. Revolving Credit Interest Rate Options.

The Borrower shall have the right to select from the following Interest Rate Options applicable to the Revolving Credit Loans (subject to the provisions above regarding Swing Loans):

(i) Base Rate Option: A fluctuating rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such interest rate to change automatically from time to time effective as of the effective date of each change in the Base Rate; or

(ii) Euro-Rate Option: A rate per annum (computed on the basis of a year of 360 days and actual days elapsed) equal to the Euro-Rate plus the Applicable Margin.

4.1.2. Rate Quotations.

The applicable Borrower may call the Administrative Agent on or before the date on which a Loan Request is to be delivered to receive an indication of the rates then in effect, but it is acknowledged that such projection shall not be binding on the Administrative Agent or the Lenders nor affect the rate of interest which thereafter is actually in effect when the election is made.

4.2 Interest Periods.

At any time when the Borrower shall select, convert to or renew a Euro-Rate Option, the Borrower shall notify the Administrative Agent at least three (3) Business Days prior to the effective date of such Euro-Rate Option by delivering a Loan Request. The notice shall specify an Interest Period during which such Interest Rate Option shall apply. Notwithstanding the preceding sentence, the following provisions shall apply to any selection of, renewal of, or conversion to a Euro-Rate Option:

4.2.1. Amount of Borrowing Tranche.

each Borrowing Tranche of Euro-Rate Loans shall be in integral multiples of $500,000 and not less than $1,000,000;

4.2.2. Renewals.

in the case of the renewal of a Euro-Rate Option at the end of an Interest Period, the first day of the new Interest Period shall be the last day of the preceding Interest Period, without duplication in payment of interest for such day.

4.3 Interest After Default.

To the extent permitted by Law, upon the occurrence of an Event of Default and until such time such Event of Default shall have been cured or waived, the Borrower may not select, convert to or renew a Euro-Rate Option, and:

4.3.1. Letter of Credit Fees, Interest Rate.

the Letter of Credit Fees and the rate of interest for each Loan otherwise applicable pursuant to Section 2.10.2 [Letter of Credit Fees], or Section 4.1 [Interest Rate Options], respectively, shall be increased by 2.0% per annum; and

4.3.2. Other Obligations.

each other Obligation hereunder if not paid when due shall bear interest at a rate per annum equal to the sum of the rate of interest applicable under the Base Rate Option plus an additional 2.0% per annum from the time such Obligation becomes due and payable and until it is paid in full.

4.3.3. Acknowledgment.

The Borrower acknowledges that the increase in rates referred to in this Section 4.3 reflects, among other things, the fact that such Loans or other amounts have become a substantially greater risk given their default status and that the Lenders are entitled to additional compensation for such risk; and all such interest shall be payable by the Borrower upon demand by Administrative Agent.

4.4 Euro-Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available.

4.4.1. Unascertainable.

If on any date on which a Euro-Rate would otherwise be determined, the Administrative Agent shall have determined that:

(i) adequate and reasonable means do not exist for ascertaining such Euro-Rate, or

(ii) a contingency has occurred which materially and adversely affects the London interbank eurodollar market relating to the Euro-Rate, the Administrative Agent shall have the rights specified in Section 4.4.3.

4.4.2. Illegality; Increased Costs; Deposits Not Available.

If at any time any Lender shall have determined that:

(i) the making, maintenance or funding of any Loan to which a Euro-Rate Option applies has been made impracticable or unlawful by compliance by such Lender in good faith with any Law or any interpretation or application thereof by any Official Body or with any request or directive of any such Official Body (whether or not having the force of Law), or

(ii) such Euro-Rate Option will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any such Loan, or

(iii) after making all reasonable efforts, deposits of the relevant amount in Dollars for the relevant Interest Period for a Loan, or to lenders generally, to which a Euro-Rate Option applies, respectively, are not available to such Lender with respect to such Loan, or to lenders generally, in the interbank eurodollar market,

then the Administrative Agent shall have the rights specified in Section 4.4.3.

4.4.3. Administrative Agent’s and Lender’s Rights.

In the case of any event specified in Section 4.4.1 above, the Administrative Agent shall promptly so notify the Lenders and the Borrower thereof, and in the case of an event specified in Section 4.4.2 above, such Lender shall promptly so notify the

Administrative Agent and endorse a certificate to such notice as to the specific circumstances of such notice, and the Administrative Agent shall promptly send copies of such notice and certificate to the other Lenders and the Borrower. Upon such date as shall be specified in such notice (which shall not be earlier than the date such notice is given), the obligation of (A) the Lenders, in the case of such notice given by the Administrative Agent, or (B) such Lender, in the case of such notice given by such Lender, to allow the Borrower to select, convert to or renew a Euro-Rate Option shall be suspended until the Administrative Agent shall have later notified the Borrower, or such Lender shall have later notified the Administrative Agent, of the Administrative Agent’s or such Lender’s, as the case may be, determination that the circumstances giving rise to such previous determination no longer exist. If at any time the Administrative Agent makes a determination under Section 4.4.1 and the Borrower have previously notified the Administrative Agent of its selection of, conversion to or renewal of a Euro-Rate Option and such Interest Rate Option has not yet gone into effect, such notification shall be deemed to provide for selection of, conversion to or renewal of the Base Rate Option otherwise available with respect to such Loans. If any Lender notifies the Administrative Agent of a determination under Section 4.4.2, the Borrower shall, subject to the Borrower’ indemnification Obligations under Section 5.6.2 [Indemnity], as to any Loan of the Lender to which a Euro-Rate Option applies, on the date specified in such notice either convert such Loan to the Base Rate Option otherwise available with respect to such Loan or prepay such Loan in accordance with Section 5.4 [Voluntary Prepayments]. Absent due notice from the Borrower of conversion or prepayment, such Loan shall automatically be converted to the Base Rate Option otherwise available with respect to such Loan upon such specified date.

4.5 Selection of Interest Rate Options.

If the Borrower fails to select a new Interest Period to apply to any Borrowing Tranche of Revolving Credit Loans under the Euro-Rate Option at the expiration of an existing Interest Period applicable to such Borrowing Tranche in accordance with the provisions of Section 4.2 [Interest Periods], the Borrower shall be deemed to have converted such Borrowing Tranche to the Base Rate Option commencing upon the last day of the existing Interest Period.

4.6 Canadian Interest Provisions.

Whenever interest is payable hereunder on the basis of a year of 365 or 360 days, for the purposes of the Interest Act (Canada), the yearly rate of interest which is equivalent to the rate payable hereunder is the rate payable hereunder multiplied by the actual number of days in the year and divided by 365 or 360, as applicable. All interest will be calculated using the nominal rate method and not the effective rate method and the deemed reinvestment principle shall not apply to such calculations.

The amount of the interest or fees exigible in applying this agreement shall not exceed the maximum rate permitted by Law. Where the amount of such interest or such fees is greater than the maximum rate, the amount shall be reduced to the highest rate which may be recovered in accordance with the applicable provisions of Law.

5. PAYMENTS

5.1 Payments.

All payments and prepayments to be made in respect of principal, interest, Commitment Fees, Letter of Credit Fees, or other fees or amounts due from the Borrower hereunder shall be payable prior to 11:00 a.m., Pittsburgh time, on the date when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Borrower, and without set-off, counterclaim or other deduction of any nature, and an action therefor shall immediately accrue. Such payments shall be made to the Administrative Agent at the Principal Office for the account of PNC Bank with respect to the Swing Loans and for the ratable accounts of the Lenders with respect to the Revolving Credit Loans, Commitment Fees related thereto, and Letter of Credit Fees in U.S. Dollars and in immediately available funds. The Administrative Agent shall promptly distribute such amounts to the applicable Lenders in immediately available funds, provided that in the event payments are received by 11:00 a.m., Pittsburgh time, by the Administrative Agent with respect to the Loans and such payments are not distributed to the Lenders on the same day received by the Administrative Agent, the Agent shall pay the Lenders entitled to such payment the Federal Funds Effective Rate with respect to the amount of such payments for each day held by the Agent and not distributed to the Lenders. The Administrative Agent’s and each Lender’s statement of account, ledger or other relevant record shall, in the absence of manifest error, be conclusive as the statement of the amount of principal of and interest on the Loans and other amounts owing under this Agreement (including the Equivalent Amounts of the applicable currencies where such computations are required) and shall be deemed an “account stated.”

5.2 Pro Rata Treatment of Lenders.

Each Revolving Credit Loan borrowing under Section 2 shall be allocated to each Lender according to its Ratable Share, and each selection of, conversion to or renewal of any Interest Rate Option and each payment or prepayment by the Borrower with respect to principal, interest, Commitment Fees related to the Revolving Credit Commitments, Letter of Credit Fees, or other fees (except for payments for fees of the Administrative Agent) or amounts due from the Borrower hereunder to the Lenders with respect to the Revolving Credit Loans, shall (except as provided in Section 4.4.3 [Administrative Agent’s and Lender’s Rights] in the case of an event specified in Section 4.4 [Euro-Rate Unascertainable; Etc.], 5.4.2 [Replacement of a Lender] or 5.6 [Additional Compensation in Certain Circumstances]) be made in proportion to the applicable Revolving Credit Loans outstanding from each Lender and, if no such Loans are then outstanding, in proportion to the Ratable Share of each Lender. Notwithstanding any of the foregoing, each borrowing or payment or prepayment by the Borrower of principal, interest, fees or other amounts with respect to Swing Loans shall be made by or to PNC Bank according to Section 2.

5.3 Interest Payment Dates.

Interest on Loans to which the Base Rate Option applies shall be due and payable in arrears on the first day of each November, February, May and August after the date hereof and

on the Expiration Date or upon acceleration of the Notes. Interest on Loans to which the Euro-Rate Option applies shall be due and payable on the last day of each Interest Period for those Loans and, if such Interest Period is longer than three (3) Months, also on the 90th day of such Interest Period. Interest on mandatory prepayments of principal under Section 5.5 [Mandatory Prepayments] shall be due on the date such mandatory prepayment is due. Interest on the principal amount of each Loan or other monetary Obligation shall be due and payable on demand after such principal amount or other monetary Obligation becomes due and payable (whether on the stated maturity date, upon acceleration or otherwise).

5.4 Voluntary Prepayments.

5.4.1. Right to Prepay.

The Borrower shall have the right at its option from time to time to prepay the Loans for which the Borrower is obligated in whole or part without premium or penalty (except as provided in Section 5.4.2 below or in Section 5.6 [Additional Compensation in Certain Circumstances]):

(i) at any time with respect to any Loan to which the Base Rate Option applies,

(ii) on the last day of the applicable Interest Period with respect to Loans to which a Euro-Rate Option applies,

(iii) on the date specified in a notice by any Lender pursuant to Section 4.4 [Euro-Rate Unascertainable, Etc.] with respect to any Loan to which a Euro-Rate Option applies.

Whenever the Borrower desires to prepay any part of the Revolving Credit Loans, it shall provide a prepayment notice to the Administrative Agent by 1:00 p.m. (i) at least one (1) Business Day prior to the date of prepayment of the Revolving Credit Loans which bear interest at the Base Rate Option, (ii) at least three (3) Business Days prior to the date of prepayment of the Revolving Credit Loans which bear interest at the Euro-Rate Option, and (iii) or no later than 1:00 p.m., Pittsburgh time, on the date of prepayment of Swing Loans. Each such notice by the Borrower shall set forth the following information:

(x) the date, which shall be a Business Day, on which the proposed prepayment is to be made;

(y) a statement indicating the application of the prepayment between the Swing Loans and the Revolving Credit Loans; and

(z) the total principal amount of such prepayment, which shall not be less than $100,000 for any Swing Loan or $500,000 for any Revolving Credit Loan.

All prepayment notices shall be irrevocable. The principal amount of the Loans for which a prepayment notice is given, together with interest on such principal amount except with respect to Loans to which the Base Rate Option applies, shall be due and payable on the date specified in such prepayment notice as the date on which the proposed prepayment is to be made. Any prepayment hereunder shall be subject to the Borrower’ Obligation to indemnify the Lenders under Section 5.6.2 [Indemnity].

5.4.2. Replacement of a Lender.

In the event any Lender (i) gives notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or Section 5.6.1 [Increased Costs, Etc.], (ii) does not fund Loans because the making of such Loans would contravene any Law applicable to such Lender, (iii) is a Non-Complying Lender, (iv) is subject to an Insolvency Event or Insolvency Proceeding, or (v) becomes subject to the control of an Official Body (other than normal and customary supervision), then the Borrower shall have the right at its option, with the consent of the Administrative Agent, which consents shall not be unreasonably withheld, to prepay the Loans of such Lender in whole, together with all interest accrued thereon, and terminate such Lender’s Commitment within ninety (90) days after (x) receipt of such Lender’s notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or 5.6.1 [Increased Costs, Etc.], (y) the date such Lender has failed to fund Loans because the making of such Loans would contravene Law applicable to such Lender, or (z) the date such Lender became subject to the control of an Official Body or subject to an Insolvency Event or Insolvency Proceeding, as applicable; provided that the Borrower shall also pay to such Lender at the time of such prepayment any amounts required under Section 5.6 [Additional Compensation in Certain Circumstances] and any accrued interest due on such amount and any related fees; provided, however, that the Commitment of such Lender shall be provided by one or more of the remaining Lenders or a replacement lender acceptable to the Administrative Agent; provided, further, the remaining Lenders shall have no obligation hereunder to increase their Commitments. Upon the occurrence of any such event, the Borrower may, at its sole expense, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.11 [Successors and Assigns]), all of its interests, rights and obligations under this Agreement and the related Loan Documents to such assignee that shall assume such obligations; provided however, a Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. Notwithstanding the foregoing, the Administrative Agent may only be replaced subject to the requirements of Section 10.14 [Successor Administrative Agent] and provided that all Letters of Credit issued by the Administrative Agent have expired or been terminated or replaced.

5.4.3. Change of Lending Office.

Each Lender agrees that upon the occurrence of any event giving rise to increased costs or other special payments under Section 4.4.2 [Illegality, Etc.] or 5.6.1 [Increased Costs, Etc.] with respect to such Lender, it will if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans or Letters of Credit affected by such event, provided that such designation is

made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of such Section. Nothing in this Section 5.4.3 shall affect or postpone any of the Obligations of the Borrower or any other Loan Party or the rights of the Administrative Agent or any Lender provided in this Agreement.

5.5 Mandatory Prepayments.

5.5.1. Recovery of Insurance Proceeds.

Within one hundred eighty (180) days of the receipt of insurance proceeds from a loss described in Section 8.1.3 (v)(c) (or, within sixty (60) days after such receipt, to the extent such Loan Party or Subsidiary has failed to provide to the Administrative Agent satisfactory evidence of such Loan Party’s or Subsidiary’s commitment to reinvest such proceeds as provided in Section 8.1.3(v)(c), to the extent that such Loan Party or Subsidiary has not reinvested such proceeds), the Borrower shall make a mandatory prepayment of principal equal to 100% of the net (after reinvestment, if any) after-tax proceeds thereof, together with accrued interest on such principal amount. Within one hundred eighty (180) days of the receipt of insurance proceeds by a Loan Party or a Subsidiary of a Loan Party from a loss which are not reinvested as described in Section 8.1.3(v)(b) (or, within sixty (60) days after such receipt, to the extent a Loan Party has failed to provide to the Administrative Agent satisfactory evidence of such Loan Party’s commitment to reinvest such proceeds as provided in Section 8.1.3(v)(b)), the Borrower shall make a mandatory prepayment of principal equal to 100% of the net (after reinvestment, if any) after-tax proceeds thereof, together with accrued interest on such principal amount.

5.5.2. Application Among Loans and Interest Rate Options.

All prepayments pursuant to this Section 5.5 shall first be applied to the Revolving Credit Loans outstanding, if any, and the excess, if any, shall be returned to the Borrower. All prepayments required pursuant to this Section 5.5 shall first be applied among the Interest Rate Options to the principal amount of the Loans subject to the Base Rate Option, then to Loans subject to a Euro-Rate Option. In accordance with Section 5.6.2 [Indemnity], the Borrower shall indemnify the Lenders for any loss or expense, including loss of margin, incurred with respect to any such prepayments applied against Loans subject to a Euro-Rate Option on any day other than the last day of the applicable Interest Period.

5.6 Additional Compensation in Certain Circumstances.

5.6.1. Increased Costs or Reduced Return Resulting from Taxes, Reserves, Capital Adequacy Requirements, Expenses, Etc.

If any Law, guideline or interpretation or any change in any Law, guideline or interpretation or application thereof by any Official Body charged with the interpretation or administration thereof or compliance with any request or directive (whether or not having the force of Law) of any central bank or other Official Body:

(i) subjects any Lender to any tax or changes the basis of taxation with respect to this Agreement, the Notes, the Loans or payments by the Borrower of principal, interest, Commitment Fees, or other amounts due from the Borrower hereunder or under the Notes (except for taxes on the overall net income of such Lender),

(ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirement against credits or commitments to extend credit extended by, or assets (funded or contingent) of, deposits with or for the account of, or other acquisitions of funds by, any Lender, or

(iii) imposes, modifies or deems applicable any capital adequacy or similar requirement (A) against assets (funded or contingent) of, or letters of credit, other credits or commitments to extend credit extended by, any Lender, or (B) otherwise applicable to the obligations of any Lender under this Agreement,

and the result of any of the foregoing is to increase the cost to, reduce the income receivable by, or impose any expense (including loss of margin) upon any Lender with respect to this Agreement, the Notes or the making, maintenance or funding of any part of the Loans (or, in the case of any capital adequacy or similar requirement, to have the effect of reducing the rate of return on any Lender’s capital, taking into consideration such Lender’s customary policies with respect to capital adequacy) by an amount which such Lender in its sole discretion deems to be material, such Lender shall from time to time notify the Borrower and the Administrative Agent of the amount determined in good faith (using any averaging and attribution methods employed in good faith) by such Lender to be necessary to compensate such Lender for such increase in cost, reduction of income, additional expense or reduced rate of return. Such notice shall set forth in reasonable detail the basis for such determination. Such amount shall be due and payable by the Borrower to such Lender ten (10) Business Days after such notice is given.

5.6.2. Indemnity.

In addition to the compensation required by Section 5.6.1 [Increased Costs, Etc.], the Borrower shall indemnify each Lender against all liabilities, losses or expenses (including loss of margin, any loss or expense incurred in liquidating or employing deposits from third parties and any loss or expense incurred in connection with funds acquired by a Lender to fund or maintain Loans subject to a Euro-Rate Option) which such Lender sustains or incurs as a consequence of any

(i) payment, prepayment, conversion or renewal of any Loan to which a Euro-Rate Option applies on a day other than the last day of the corresponding Interest Period (whether or not such payment or prepayment is mandatory, voluntary or automatic and whether or not such payment or prepayment is then due),

(ii) attempt by the Borrower to revoke (expressly, by later inconsistent notices or otherwise) in whole or part any Loan Requests under Section 2.5 [Revolving Credit Loan Requests] or Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.4 [Voluntary Prepayments], or

(iii) default by a Loan Party in the performance or observance of any covenant or condition contained in this Agreement or any other Loan Document, including any failure of the Borrower to pay when due (by acceleration or otherwise) any principal, interest, Commitment Fee or any other amount due hereunder.

If any Lender sustains or incurs any such loss or expense, it shall from time to time notify the Borrower of the amount determined in good faith by such Lender (which determination may include such assumptions, allocations of costs and expenses and averaging or attribution methods as such Lender shall deem reasonable) to be necessary to indemnify such Lender for such loss or expense. Such notice shall set forth in reasonable detail the basis for such determination. Such amount shall be due and payable by the applicable Borrower(s) to such Lender ten (10) Business Days after such notice is given.

5.7 Collections; Administrative Agent’s Right to Notify Account Debtors.

After the occurrence of any Event of Default, the Administrative Agent may, and upon request of the Required Lenders, shall (i) notify any or all Account Debtors that the Accounts have been assigned to the Lenders and that the Lenders have a security interest therein, and (ii) direct such Account Debtors to make all payments due from them to the Borrower and the Guarantors upon the Accounts directly to the Administrative Agent or to a lockbox designated by the Administrative Agent. The Administrative Agent shall promptly furnish the Borrower with a copy of any such notice sent. Any such notice, in the Administrative Agent’s sole discretion, may be sent on the Borrower’s stationery, in which event the Borrower shall co-sign such notice with the Administrative Agent. To the extent that any Law or custom or any contract or agreement with any Account Debtor requires notice to or the approval of the Account Debtor in order to perfect such assignment of a security interest in Accounts, the Borrower agrees to give such notice or obtain such approval.

5.8 Judgment Currency.

5.8.1. Currency Conversion Procedures for Judgments.

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in any currency (the “Original Currency”) into another currency (the “Other Currency”), the parties hereby agree, to the fullest extent permitted by Law, that the rate of exchange used shall be that at which in accordance with normal lending procedures each Lender could purchase the Original Currency with the Other Currency after any premium and costs of exchange on the Business Day preceding that on which final judgment is given.

5.8.2. Indemnity in Certain Events.

The obligation of Borrower in respect of any sum due from Borrower to any Lender hereunder shall, notwithstanding any judgment in an Other Currency, whether pursuant to a judgment or otherwise, be discharged only to the extent that, on the Business Day following receipt by any Lender of any sum adjudged to be so due in such Other Currency, such Lender may in accordance with normal lending procedures purchase the Original Currency with

such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to such Lender in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment or payment, to indemnify such Lender against such loss.

If an Event of Default specified under Sections 9.1.1 through 9.1.14 shall occur and be continuing, the Lenders and the Administrative Agent shall be under no further obligation to make Loans or issue Letters of Credit, as the case may be, and the Administrative Agent may, and upon the request of the Required Lenders, shall (i) by written notice to the Borrower, declare the unpaid principal amount of the Notes then outstanding and all interest accrued thereon, any unpaid fees and all other Indebtedness of the Borrower to the Lenders hereunder and thereunder to be forthwith due and payable, and the same shall thereupon become and be immediately due and payable to the Administrative Agent for the benefit of each Lender without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived, and (ii) require the Borrower to, and the Borrower shall thereupon, deposit in a non-interest-bearing account with the Administrative Agent, as cash collateral for its Obligations under the Loan Documents, an amount equal to the maximum amount currently or at any time thereafter available to be drawn on all outstanding Letters of Credit, and the Borrower hereby pledges to the Administrative Agent and the Lenders, and grants to the Administrative Agent and the Lenders a security interest in, all such cash as security for such Obligations. Upon the curing of all existing Events of Default to the satisfaction of the Required Lenders, the Administrative Agent shall return such cash collateral to the Borrower; and

9.2.2. Bankruptcy, Insolvency or Reorganization Proceedings.

If an Event of Default specified under Section 9.1.15 [Involuntary Proceedings] or 9.1.16 [Voluntary Proceedings] shall occur, the Lenders shall be under no further obligations to make Loans hereunder and the unpaid principal amount of the Loans then outstanding and all interest accrued thereon, any unpaid fees and all other Obligations shall be immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived; and

(i) first, to reimburse the Administrative Agent and the Lenders for out-of-pocket costs, expenses and disbursements, including reasonable attorneys’ and

paralegals’ fees and legal expenses, incurred by the Administrative Agent or the Lenders in connection with realizing on the Collateral or collection of any Obligations of any of the Loan Parties under any of the Loan Documents, including advances made by the Lenders or any one of them or the Administrative Agent for the reasonable maintenance, preservation, protection or enforcement of, or realization upon, the Collateral, including advances for taxes, insurance, repairs and the like and reasonable expenses incurred to sell or otherwise realize on, or prepare for sale or other realization on, any of the Collateral;

All Liens granted under the Security Agreements, the Patent Trademark and Copyright Security Agreement, the Pledge Agreement and any other Loan Document (the “Collateral Documents”) shall secure ratably and on a pari passu basis (i) the Obligations in favor of the Administrative Agent and the Lenders hereunder and (ii) the Obligations incurred by any of the Loan Parties in favor of any Lender which provides a Lender-Provided Interest Rate Hedge (the “IRH Provider”). The Administrative Agent under the Collateral Documents shall be deemed to serve and is appointed as the collateral agent (the “Collateral Agent”) for the IRH Provider and the Lenders hereunder, provided that the Collateral Agent shall comply with the instructions and directions of the Administrative Agent (or the Lenders under this Agreement to the extent that this Agreement or any other Loan Documents empowers the Lenders to direct the Administrative Agent), as to all matters relating to the Collateral, including the maintenance and disposition thereof. No IRH Provider (except in its capacity as a Lender hereunder) shall be entitled or have the power to direct or instruct the Collateral Agent on any such matters or to control or direct in any manner the maintenance or disposition of the Collateral.

9.2.6. Other Rights and Remedies.

In addition to all of the rights and remedies contained in this Agreement or in any of the other Loan Documents, the Administrative Agent shall have all of the rights and remedies of a secured party under the Uniform Commercial Code or other applicable Law, all of which rights and remedies shall be cumulative and non-exclusive, to the extent permitted by Law.

10. THE ADMINISTRATIVE AGENT

10.1 Appointment.

Each Lender hereby irrevocably designates, appoints and authorizes PNC Bank to act as Administrative Agent for such Lender under this Agreement and to execute and deliver or accept on behalf of each of the Lenders the other Loan Documents. Each Lender hereby irrevocably authorizes, and each holder of any Note by the acceptance of a Note shall be deemed irrevocably to authorize, the Administrative Agent to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and any other instruments and agreements referred to herein, and to exercise such powers and to perform such duties hereunder as are specifically delegated to or required of the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto. PNC Bank agrees to act as the Administrative Agent on behalf of the Lenders to the extent provided in this Agreement.

None of the Lenders designated on the facing page or signature pages of this Agreement as a “Documentation Agent” or as a “Syndication Agent” shall have any right, power, obligation, liability, responsibility, or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified as the “Documentation Agent” or as a “Syndication Agent” shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied and will not rely on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

10.2 Delegation of Duties.

The Administrative Agent may perform any of its duties hereunder by or through agents or employees (provided such delegation does not constitute a relinquishment of its duties as Administrative Agent) and, subject to Sections 10.5 [Reimbursement of Administrative Agent by Borrower, Etc.] and 10.6, shall be entitled to engage and pay for the advice or services of any attorneys, accountants or other experts concerning all matters pertaining to its duties hereunder and to rely upon any advice so obtained.

10.3 Nature of Duties; Independent Credit Investigation.

The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and no implied covenants, functions, responsibilities, duties, obligations, or liabilities shall be read into this Agreement or otherwise exist. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement a fiduciary or trust relationship in respect of

any Lender; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement except as expressly set forth herein. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Each Lender expressly acknowledges (i) that the Administrative Agent has not made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of any of the Loan Parties, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender; (ii) that it has made and will continue to make, without reliance upon the Administrative Agent, its own independent investigation of the financial condition and affairs and its own appraisal of the creditworthiness of each of the Loan Parties in connection with this Agreement and the making and continuance of the Loans hereunder; and (iii) except as expressly provided herein, that the Administrative Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the making of any Loan or at any time or times thereafter.

10.4 Actions in Discretion of Administrative Agent; Instructions From the Lenders.

The Administrative Agent agrees, upon the written request of the Required Lenders, to take or refrain from taking any action of the type specified as being within the Administrative Agent’s rights, powers or discretion herein, provided that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement or any other Loan Document or applicable Law. In the absence of a request by the Required Lenders, the Administrative Agent shall have authority, in its sole discretion, to take or not to take any such action, unless this Agreement specifically requires the consent of the Required Lenders or all of the Lenders. Any action taken or failure to act pursuant to such instructions or discretion shall be binding on the Lenders, subject to Section 10.6 [Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders (or if required under Section 11.1, all the Lenders), or in the absence of such instructions, in the absolute discretion of the Administrative Agent.

10.5 Reimbursement and Indemnification of Administrative Agent by the Borrower.

The Borrower unconditionally agrees to pay or reimburse the Administrative Agent and hold the Administrative Agent harmless against (a) liability for the payment of all reasonable out-of-pocket costs, expenses and disbursements, including fees and expenses of counsel (including the allocated costs of staff counsel), appraisers and environmental consultants, incurred by the Administrative Agent (i) in connection with the development, negotiation, preparation, printing, execution, administration, syndication, interpretation and performance of this Agreement and the other Loan Documents, (ii) relating to any requested amendments,

waivers or consents pursuant to the provisions hereof, (iii) in connection with the enforcement of this Agreement or any other Loan Document or collection of amounts due hereunder or thereunder or the proof and allowability of any claim arising under this Agreement or any other Loan Document, whether in bankruptcy or receivership proceedings or otherwise, (iv) in any workout or restructuring or in connection with the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection or bankruptcy proceedings, and (v) in connection with any Environmental Complaint threatened or asserted against the Administrative Agent or the Lenders in any way relating to or arising out of this Agreement or any other Loan Documents (including, without limitation, the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection or bankruptcy proceedings or in any workout or restructuring), and (b) all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent, in its capacity as such, in any way relating to or arising out of (i) this Agreement or any other Loan Documents or any action taken or omitted by the Administrative Agent hereunder or thereunder, and (ii) any Environmental Complaint in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by the Administrative Agent hereunder or thereunder, provided that no Borrower shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements if the same results from the Administrative Agent’s gross negligence or willful misconduct, or if the Borrower was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that the Borrower shall remain liable to the extent such failure to give notice does not result in a loss to the Borrower), or if the same results from a compromise or settlement agreement entered into without the consent of the Borrower, which shall not be unreasonably withheld. In addition, the Borrower agrees to reimburse and pay all reasonable out-of-pocket expenses of the Administrative Agent’s regular employees and agents engaged periodically to perform audits of the Loan Parties’ books, records and business properties.

10.6 Exculpatory Provisions; Limitation of Liability.

Neither the Administrative Agent nor any of its directors, officers, employees, agents, attorneys or Affiliates shall (a) be liable to any Lender for any action taken or omitted to be taken by it or them hereunder, or in connection herewith including pursuant to any Loan Document, unless caused by its or their own gross negligence or willful misconduct, (b) be responsible in any manner to any of the Lenders for the effectiveness, enforceability, genuineness, validity or the due execution of this Agreement or any other Loan Documents or for any recital, representation, warranty, document, certificate, report or statement herein or made or furnished under or in connection with this Agreement or any other Loan Documents, or (c) be under any obligation to any of the Lenders to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions hereof or thereof on the part of the Loan Parties, or the financial condition of the Loan Parties, or the existence or possible existence of any Event of Default or Potential Default. No claim may be made by any of the Loan Parties, any Lender, the Administrative Agent or any of their respective Subsidiaries against the Administrative Agent, any Lender or any of their respective directors, officers, employees,

agents, attorneys or Affiliates, or any of them, for any special, indirect or consequential damages or, to the fullest extent permitted by Law, for any punitive damages in respect of any claim or cause of action (whether based on contract, tort, statutory liability, or any other ground) based on, arising out of or related to any Loan Document or the transactions contemplated hereby or any act, omission or event occurring in connection therewith, including the negotiation, documentation, administration or collection of the Loans, and each of the Loan Parties, (for itself and on behalf of each of its Subsidiaries), the Administrative Agent and each Lender hereby waive, release and agree never to xxx upon any claim for any such damages, whether such claim now exists or hereafter arises and whether or not it is now known or suspected to exist in its favor. Each Lender agrees that, except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder or given to the Administrative Agent for the account of or with copies for the Lenders, the Administrative Agent and each of its directors, officers, employees, agents, attorneys or Affiliates shall not have any duty or responsibility to provide any Lender with an credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Loan Parties which may come into the possession of the Administrative Agent or any of its directors, officers, employees, agents, attorneys or Affiliates.

10.7 Reimbursement and Indemnification of Administrative Agent by Lenders.

Each Lender agrees to reimburse and indemnify, defend and save the Administrative Agent (to the extent not reimbursed by the Borrower and without limiting the Obligation of the Borrower to do so) in proportion to its Ratable Share harmless from and against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements, including attorneys’ fees and disbursements (including the allocated costs of staff counsel), and costs of appraisers and environmental consultants, of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by the Administrative Agent hereunder or thereunder, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (a) if the same results from the Administrative Agent’s gross negligence or willful misconduct, or (b) if such Lender was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that such Lender shall remain liable to the extent such failure to give notice does not result in a loss to the Lender), or (c) if the same results from a compromise and settlement agreement entered into without the consent of such Lender, which shall not be unreasonably withheld. In addition, each Lender agrees promptly upon demand to reimburse the Administrative Agent (to the extent not reimbursed by the Borrower and without limiting the Obligation of the Borrower to do so) in proportion to its Ratable Share for all amounts due and payable by the Borrower to the Administrative Agent in connection with the Administrative Agent’s periodic audit of the Loan Parties’ books, records and business properties. For the avoidance of doubt, references in this Section to the Administrative Agent shall include the Administrative Agent in its capacity as Collateral Agent under each of the Security Trust Deed and Fixed and Floating Charge (Australia).

10.8 Reliance by Administrative Agent.

The Administrative Agent shall be entitled to rely upon any writing, telegram, telex or teletype message, resolution, notice, consent, certificate, letter, cablegram, statement, order or other document or conversation by telephone or otherwise believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon the advice and opinions of counsel and other professional advisers selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder unless it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

10.9 Notice of Default.

The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Potential Default or Event of Default unless the Administrative Agent has received written notice from a Lender or a Borrower referring to this Agreement, describing such Potential Default or Event of Default.

10.10 Notices.

The Administrative Agent shall promptly send to each Lender a copy of all notices received from the Borrower pursuant to the provisions of this Agreement or the other Loan Documents promptly upon receipt thereof. The Administrative Agent shall promptly notify the Borrower and the other Lenders of each change in the Base Rate and the effective date thereof.

10.11 Lenders in Their Individual Capacities; Administrative Agent in its Individual Capacity.

With respect to its Revolving Credit Commitment and any Revolving Credit Loans, made by it and any other rights and powers given to it as a Lender hereunder or under any of the other Loan Documents, the Administrative Agent shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” and “Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. PNC Bank and its Affiliates and each of the Lenders and their respective Affiliates may, without liability to account, except as prohibited herein, make loans to, issue letters of credit for the account of, acquire equity interests in, accept deposits from, discount drafts for, act as trustee under indentures of, and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with, the Loan Parties and their Affiliates, in the case of the Administrative Agent, as though it were not acting as Administrative Agent hereunder and in the case of each Lender, as though such Lender were not a Lender hereunder, in each case without notice to or consent of the other Lenders. The Lenders acknowledge that, pursuant to such activities, the Administrative Agent or its Affiliates may (i) receive information regarding the Loan Parties or any of their Subsidiaries or Affiliates (including information that may be subject to confidentiality obligations in favor of the Loan Parties or such Subsidiary or Affiliate) and

100

acknowledge that the Administrative Agent shall be under no obligation to provide such information to them, and (ii) accept fees and other consideration from the Loan Parties for services in connection with this Agreement and otherwise without having to account for the same to the Lenders.

10.12 Holders of Notes.

The Administrative Agent may deem and treat any payee of any Note as the owner thereof for all purposes hereof unless and until written notice of the assignment or transfer thereof shall have been filed with the Administrative Agent. Any request, authority or consent of any Person who at the time of making such request or giving such authority or consent is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

10.13 Equalization of Lenders.

The Lenders, for themselves and any Affiliates and any Australian correspondent bank which are owed Obligations, and the holders of any participations in any Notes, agree among themselves that, with respect to all amounts received by any Lender, any such Affiliate, or any such holder or Australian correspondent bank for application on any Obligation hereunder (including, without limitation, any Lender-Provided Interest Rate Hedge and any Lender-Provided Treasury Arrangement) or under any Note or under any such participation, whether received by voluntary payment, by realization upon security, by the exercise of the right of set-off or banker’s lien, by counterclaim or by any other non-pro rata source, equitable adjustment will be made in the manner stated in the following sentence so that, in effect, all such excess amounts will be shared ratably among the Lenders and such holders in proportion to their interests in payments under the Notes and other Obligations, except as otherwise provided in Section 4.4.3 [Administrative Agent’s and Lender’s Rights], 5.4.2 [Replacement of a Lender] or 5.6 [Additional Compensation in Certain Circumstances]. The Lenders, any such Affiliate, or any such holder or Australian correspondent bank receiving any such amount shall purchase for cash from each of the other Lenders an interest in such Lender’s Loans in such amount as shall result in a ratable participation by the Lenders, such Affiliates and each such holder and Australian correspondent bank in the aggregate unpaid amount under the Notes and the other Obligations, provided that if all or any portion of such excess amount is thereafter recovered from the Lender, such Affiliate or the holder or Australian correspondent bank making such purchase, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by law (including court order) to be paid by the Lender, such Affiliate or the holder or Australian correspondent bank making such purchase.

10.14 Successor Administrative Agent.

The Administrative Agent (i) may resign as Administrative Agent or (ii) shall resign if such resignation is requested by the Required Lenders (if the Administrative Agent is a Lender, the Administrative Agent’s Loans and its Commitment shall be considered in determining whether the Required Lenders have requested such resignation) or required by Section 5.4.2 [Replacement of a Lender], in either case of (i) or (ii) by giving not less than thirty

101

(30) days’ prior written notice to the Borrower. If the Administrative Agent shall resign under this Agreement, then either (a) the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, subject to the consent of the Borrower, such consent not to be unreasonably withheld, or (b) if a successor agent shall not be so appointed and approved within the thirty (30) day period following the Administrative Agent’s notice to the Lenders of its resignation, then the Administrative Agent shall appoint, with the consent of the Borrower, such consent not to be unreasonably withheld, a successor agent who shall serve as Administrative Agent until such time as the Required Lenders appoint and the Borrower consents to the appointment of a successor agent. Upon its appointment pursuant to either clause (a) or (b) above, such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent, effective upon its appointment, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement. After the resignation of any Administrative Agent hereunder, the provisions of this Section 10 shall inure to the benefit of such former Administrative Agent and such former Administrative Agent shall not by reason of such resignation be deemed to be released from liability for any actions taken or not taken by it while it was an Administrative Agent under this Agreement.

10.15 Administrative Agent’s Fee.

The Borrower shall pay to the Administrative Agent nonrefundable fees under the terms of a Fee Letter dated September 26, 2008, between the Borrower and the Administrative Agent, as amended from time to time (the “Agent’s Letter”).

10.16 Availability of Funds.

The Administrative Agent may assume that each Lender has made or will make the proceeds of a Loan available to the Administrative Agent unless the Administrative Agent shall have been notified by such Lender on or before the later of (1) the close of Business on the Business Day preceding the Borrowing Date with respect to such Loan or two (2) hours before the time on which the Administrative Agent actually funds the proceeds of such Loan to the Borrower (whether using its own funds pursuant to this Section 10.16 or using proceeds deposited with the Administrative Agent by the Lenders and whether such funding occurs before or after the time on which Lenders are required to deposit the proceeds of such Loan with the Administrative Agent). The Administrative Agent may, in reliance upon such assumption (but shall not be required to), make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such amount on demand from such Lender (or, if such Lender fails to pay such amount forthwith upon such demand from the Borrower) together with interest thereon, in respect of each day during the period commencing on the date such amount was made available to the Borrower and ending on the date the Administrative Agent recovers such amount, at a rate per annum equal to (i) the Federal Funds Effective Rate during the first three (3) days after such interest shall begin to accrue and (ii) the applicable interest rate in respect of such Loan after the end of such three-day period.

102

10.17 Calculations.

In the absence of gross negligence or willful misconduct, the Administrative Agent shall not be liable for any error in computing the amount payable to any Lender whether in respect of the Loans, fees or any other amounts due to the Lenders under this Agreement. In the event an error in computing any amount payable to any Lender is made, the Administrative Agent, the Borrower and each affected Lender shall, forthwith upon discovery of such error, make such adjustments as shall be required to correct such error, and any compensation therefor will be calculated at the Federal Funds Effective Rate.

10.18 Beneficiaries.

Except as expressly provided herein, the provisions of this Section 10 are solely for the benefit of the Administrative Agent and the Lenders, and the Loan Parties shall not have any rights to rely on or enforce any of the provisions hereof. In performing its functions and duties under this Agreement, the Administrative Agent shall act solely as agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any of the Loan Parties.

10.19 No Reliance on Agent’s Customer Identification Program.

Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA Patriot Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any of the Loan Parties, their Affiliates or their agents, the Loan Documents or the transactions hereunder or contemplated hereby: (1) any identity verification procedures, (2) any recordkeeping, (3) comparisons with government lists, (4) customer notices or (5) other procedures required under the CIP Regulations or such other Laws.

10.20 Power of Attorney for Quebec Purposes.

For greater certainty, and without limiting the powers of the Administrative Agent hereunder or under any of the Loan Documents, each of the Lenders hereby acknowledges that the Administrative Agent shall, for the purposes of holding any security granted under the Québec Security pursuant to the laws of the Province of Quebec to secure payment of the Demand Debenture (or any similar instruments), be the holder of an irrevocable power of attorney (fondé de pouvoir) (within the meaning of Article 2692 of the Civil Code of Quebec) for all present and future Lenders and holders of such Demand Debenture. Each of the Lenders hereby constitutes, to the extent necessary, the Administrative Agent as the holder of such irrevocable power of attorney (fondé de pouvoir) in order to hold security granted under the Quebec Security in the Province of Quebec to secure the Demand Debenture (or any similar instrument). Each assignee of a Lender shall be deemed to have confirmed and ratified the

103

constitution of the Administrative Agent as the holder of such irrevocable power of attorney (fondé de pouvoir) by execution of the relevant Assignment and Assumption Agreement. Notwithstanding the provisions of Section 32 of the Special Powers of Legal Persons Act (Quebec), the Administrative Agent may acquire and be the holder of the Demand Debenture (or any similar instrument). Each of the Loan Parties hereby acknowledges that the Demand Debenture constitutes a title of indebtedness, as such term is used in Article 2692 of the Civil Code of Quebec. The Administrative Agent hereby acknowledges and accepts the Quebec Security as forming part of the Loan Documents and agrees to be bound by the provisions thereof.

Notwithstanding Section 11.8 hereof, the provisions of this Section 10.20 shall be governed by the laws of the Province of Quebec and the federal laws of Canada applicable therein.

11. MISCELLANEOUS

11.1 Modifications, Amendments or Waivers.

With the written consent of the Required Lenders, the Administrative Agent, acting on behalf of all the Lenders, and the Borrower, on behalf of the Loan Parties, may from time to time enter into written agreements amending or changing any provision of this Agreement or any other Loan Document or the rights of the Lenders or the Loan Parties hereunder or thereunder, or may grant written waivers or consents to a departure from the due performance of the Obligations of the Loan Parties hereunder or thereunder. Any such agreement, waiver or consent made with such written consent shall be effective to bind all the Lenders and the Loan Parties; provided, that, without the written consent of all the Lenders, no such agreement, waiver or consent may be made which will:

11.1.1. Increase of Commitment; Extension of Expiration Date.

Except as set forth in Section 2.12, increase the amount of the Revolving Credit Commitment of any Lender hereunder or extend the Expiration Date;

11.1.2. Extension of Payment; Reduction of Principal Interest or Fees; Modification of Terms of Payment.

Whether or not any Loans are outstanding, extend the time for payment of principal or interest of any Loan (excluding the due date of any mandatory prepayment of a Loan except for mandatory prepayments required under Section 5.5.5 and mandatory reductions of the Commitments on the Expiration Date), the Commitment Fee or any other fee payable to any Lender, or reduce the principal amount of or the rate of interest borne by any Loan or reduce the Commitment Fee or any other fee payable to any Lender, or otherwise affect the terms of payment of the principal of or interest of any Loan, the Commitment Fee or any other fee payable to any Lender;

104

11.1.3. Release of Collateral or Guarantor.

Except for (i) sales of assets or capital stock permitted by Section 8.2.7 [Disposition of Assets or Subsidiaries], and (ii) releases of Guarantors and Collateral as authorized under Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures], release all or substantially all the Collateral, any Guarantor from its Obligations under any Guaranty Agreement or any other security for any of the Loan Parties’ Obligations; or

11.1.4. Miscellaneous.

Amend Section 5.2 [Pro Rata Treatment of Lenders], 10.6 [Exculpatory Provisions, Etc.] or 10.13 [Equalization of Lenders] or this Section 11.1, alter any provision regarding the pro rata treatment of the Lenders, change the definition of Required Lenders, or change any requirement providing for the Lenders or the Required Lenders to authorize the taking of any action hereunder;

provided, further, that (i) no agreement, waiver or consent which would modify the interests, rights or obligations of the Administrative Agent in its capacity as Administrative Agent or as the issuer of Letters of Credit shall be effective without the written consent of the Administrative Agent, and (ii) no agreement, waiver or consent which would modify the interests, rights or obligations of any Lender in its capacity as an Issuing Bank hereunder shall be effective without the written consent of such Lender. The Administrative Agent shall, upon request of the Borrower, and without the consent of any Lender if no Potential Default or Event of Default exists, release from the Lien of the relevant Loan Documents any Collateral upon the sale or disposition thereof which is permitted by Section 8.2.7. Upon the request of the Borrower and provided no Event of Default has occurred and is continuing, the Administrative Agent may, in its discretion, release from the Lien of the relevant Loan Documents any Collateral that is subject to a Purchase Money Security Interest permitted under this Agreement to the extent such release is requested by the party providing such purchase money financing.

11.2 No Implied Waivers; Cumulative Remedies; Writing Required.

No course of dealing and no delay or failure of the Administrative Agent or any Lender in exercising any right, power, remedy or privilege under this Agreement or any other Loan Document shall affect any other or future exercise thereof or operate as a waiver thereof, nor shall any single or partial exercise thereof or any abandonment or discontinuance of steps to enforce such a right, power, remedy or privilege preclude any further exercise thereof or of any other right, power, remedy or privilege. The rights and remedies of the Administrative Agent and the Lenders under this Agreement and any other Loan Documents are cumulative and not exclusive of any rights or remedies which they would otherwise have. Any waiver, permit, consent or approval of any kind or character on the part of any Lender of any breach or default under this Agreement or any such waiver of any provision or condition of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.

105

11.3 Reimbursement and Indemnification of Lenders by the Borrower; Taxes.

The Borrower agrees unconditionally upon demand to pay or reimburse to each Lender (other than the Administrative Agent, as to which the Borrower’ Obligations are set forth in Section 10.5 [Reimbursement of Administrative Agent By Borrower, Etc.]) and to save such Lender harmless against (i) liability for the payment of all reasonable out-of-pocket costs, expenses and disbursements (including fees and expenses of counsel (including allocated costs of staff counsel) for each Lender except with respect to the following clauses (a) and (b)), incurred by such Lender (a) in connection with the administration and interpretation of this Agreement, and other instruments and documents to be delivered hereunder, (b) relating to any amendments, waivers or consents pursuant to the provisions hereof, (c) in connection with the enforcement of this Agreement or any other Loan Document, or collection of amounts due hereunder or thereunder or the proof and allowability of any claim arising under this Agreement or any other Loan Document, whether in bankruptcy or receivership proceedings or otherwise, (d) in any workout or restructuring or in connection with the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection, insolvency, or bankruptcy proceedings, and (e) in connection with any Environmental Complaint threatened or asserted against the Lender in any way relating to or arising out of this Agreement or any other Loan Documents (including, without limitation, the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection or bankruptcy proceedings or in any workout or restructuring), or (ii) all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against such Lender, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by such Lender hereunder or thereunder, provided that no Borrower shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (A) if the same results from such Lender’s gross negligence or willful misconduct, or (B) if the Borrower was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that the Borrower shall remain liable to the extent such failure to give notice does not result in a loss to the Borrower), or (C) if the same results from a compromise or settlement agreement entered into without the consent of the Borrower, which shall not be unreasonably withheld. The Lenders will attempt to minimize the fees and expenses of legal counsel for the Lenders which are subject to reimbursement by the Borrower hereunder by considering the usage of one law firm to represent the Lenders and the Administrative Agent if appropriate under the circumstances. The Borrower agrees unconditionally to pay all stamp, document, transfer, recording, goods and services (or value added), or filing taxes or fees and similar impositions now or hereafter determined by the Administrative Agent or any Lender to be payable in connection with this Agreement or any other Loan Document or the transactions contemplated thereby, and the Borrower agrees unconditionally to save the Administrative Agent and the Lenders harmless from and against any and all present or future claims, liabilities or losses with respect to or resulting from any omission to pay or delay in paying any such taxes, fees or impositions.

106

11.4 Holidays.

Whenever payment of a Loan to be made or taken hereunder shall be due on a day which is not a Business Day such payment shall be due on the next Business Day (except as provided in Section 4.2 [Interest Periods] with respect to Interest Periods under the Euro-Rate Option) and such extension of time shall be included in computing interest and fees, except that the Loans shall be due on the Business Day preceding the Expiration Date if the Expiration Date is not a Business Day. Whenever any payment or action to be made or taken hereunder (other than payment of the Loans) shall be stated to be due on a day which is not a Business Day, such payment or action shall be made or taken on the next following Business Day, and such extension of time shall not be included in computing interest or fees, if any, in connection with such payment or action.

11.5 Funding by Branch, Subsidiary or Affiliate.

11.5.1. Notional Funding.

Each Lender shall have the right from time to time, without notice to the Borrower, to deem any branch, Subsidiary or Affiliate (which for the purposes of this Section 11.5 shall mean any corporation or association which is directly or indirectly controlled by or is under direct or indirect common control with any corporation or association which directly or indirectly controls such Lender) of such Lender to have made, maintained or funded any Loan to which the Euro-Rate Option applies at any time, provided that immediately following (on the assumption that a payment were then due from the Borrower to such other office), and as a result of such change, the Borrower would not be under any greater financial obligation pursuant to Section 5.6 [Additional Compensation in Certain Circumstances] than it would have been in the absence of such change. Notional funding offices may be selected by each Lender without regard to such Lender’s actual methods of making, maintaining or funding the Loans or any sources of funding actually used by or available to such Lender.

11.5.2. Actual Funding.

Each Lender shall have the right from time to time to make or maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such Lender to make or maintain such Loan subject to the last sentence of this Section 11.5.2. If any Lender causes a branch, Subsidiary or Affiliate to make or maintain any part of the Loans hereunder, all terms and conditions of this Agreement shall, except where the context clearly requires otherwise, be applicable to such part of the Loans to the same extent as if such Loans were made or maintained by such Lender, but in no event shall any Lender’s use of such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans hereunder cause such Lender or such branch, Subsidiary or Affiliate to incur any cost or expenses payable by the Borrower hereunder or require the Borrower to pay any other compensation to any Lender (including any expenses incurred or payable pursuant to Section 5.6 [Additional Compensation in Certain Circumstances]) which would otherwise not be incurred.

107

11.6 Notices.

Any notice, request, demand, direction or other communication (for purposes of this Section 11.6 only, a “Notice”) to be given to or made upon any party hereto under any provision of this Agreement shall be given or made by telephone or in writing (which includes means of electronic transmission (i.e., “e-mail”) or facsimile transmission or by setting forth such Notice on a site on the World Wide Web (a “Website Posting”) if Notice of such Website Posting (including the information necessary to access such site) has previously been delivered to the applicable parties hereto by another means set forth in this Section 11.6) in accordance with this Section 11.6. Any such Notice must be delivered to the applicable parties hereto at the addresses and numbers set forth under their respective names on Schedule 1.1(B) hereof or in accordance with any subsequent unrevoked Notice from any such party that is given in accordance with this Section 11.6. Any Notice shall be effective:

(i) In the case of hand-delivery, when delivered;

(ii) If given by mail, four days after such Notice is deposited with the United States Postal Service, with first-class postage prepaid, return receipt requested or Australia Post, by registered mail (as the case may require);

(iii) In the case of a telephonic Notice, when a party is contacted by telephone, if delivery of such telephonic Notice is confirmed no later than the next Business Day by hand delivery, a facsimile or electronic transmission, a Website Posting or overnight courier delivery of a confirmatory notice (received at or before noon on such next Business Day);

(iv) In the case of a facsimile transmission, when sent to the applicable party’s facsimile machine’s telephone number if the party sending such Notice receives confirmation of the delivery thereof from its own facsimile machine;

(v) In the case of electronic transmission, when actually received;

(vi) In the case of a Website Posting, upon delivery of a Notice of such posting (including the information necessary to access such web site) by another means set forth in this Section 11.6; and

(vii) If given by any other means (including by overnight courier), when actually received.

Any Lender giving a Notice to a Loan Party shall concurrently send a copy thereof to the Administrative Agent, and the Administrative Agent shall promptly notify the other Lenders of its receipt of such Notice.

11.7 Severability.

The provisions of this Agreement are intended to be severable. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction, such

108

provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without in any manner affecting the validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction.

11.8 Governing Law.

Each Letter of Credit and Section 2.10 [Letter of Credit Subfacility] shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, as the same may be revised or amended from time to time, and to the extent not inconsistent therewith, the internal laws of the Commonwealth of Pennsylvania without regard to its conflict of laws principles, and the balance of this Agreement shall be deemed to be a contract under the Laws of the Commonwealth of Pennsylvania and for all purposes shall be governed by and construed and enforced in accordance with the internal laws of the Commonwealth of Pennsylvania without regard to its conflict of laws principles.

11.9 Prior Understanding.

This Agreement and the other Loan Documents supersede all prior understandings and agreements, whether written or oral, between the parties hereto and thereto relating to the transactions provided for herein and therein, including any prior confidentiality agreements and commitments.

11.10 Duration; Survival.

All representations and warranties of the Loan Parties contained herein or made in connection herewith shall survive the making of Loans and issuance of Letters of Credit and shall not be waived by the execution and delivery of this Agreement, any investigation by the Administrative Agent or the Lenders, the making of Loans, issuance of Letters of Credit, or payment in full of the Loans. All covenants and agreements of the Loan Parties contained in Sections 8.1 [Affirmative Covenants], 8.2 [Negative Covenants] and 8.3 [Reporting Requirements] herein shall continue in full force and effect from and after the date hereof so long as the Borrower may borrow or request Letters of Credit hereunder and until termination of the Commitments and payment in full of the Loans and expiration or termination of all Letters of Credit. All covenants and agreements of the Borrower contained herein relating to the payment of principal, interest, premiums, additional compensation or expenses and indemnification, including those set forth in the Notes, Section 5 [Payments] and Sections 10.5 [Reimbursement of Administrative Agent by Borrower, Etc.], 10.7 [Reimbursement of Administrative Agent by Lenders, Etc.] and 11.3 [Reimbursement of Lenders by Borrower; Etc.], shall survive payment in full of the Loans, expiration or termination of the Letters of Credit and termination of the Commitments.

11.11 Successors and Assigns.

(i) This Agreement shall be binding upon and shall inure to the benefit of the Lenders, the Administrative Agent, the Loan Parties and their respective successors

109

and assigns, except that none of the Loan Parties may assign or transfer any of its rights and Obligations hereunder or any interest herein. Each Lender may, at its own cost, make assignments of or sell participations in all or any part of its Commitments and the Loans made by it to one or more banks or other entities, subject to the consent of the Borrower and the Administrative Agent with respect to any assignee, such consent not to be unreasonably withheld, provided that (1) no consent of the Borrower shall be required (A) if an Event of Default exists and is continuing, or (B) in the case of an assignment by a Lender to an Affiliate of such Lender, and (2) any assignment by a Lender to a Person other than an Affiliate of such Lender may not be made in amounts less than the lesser of $5,000,000 or the amount of the assigning Lender’s Commitment, provided that any Lender party to this Agreement as of the Closing Date (each, an “Existing Lender”) may make assignments to any other Existing Lender in any amount (without regard to the $5,000,000 limitation in clause (2)). In the case of an assignment, upon receipt by the Administrative Agent of the Assignment and Assumption Agreement, the assignee shall have, to the extent of such assignment (unless otherwise provided therein), the same rights, benefits and obligations as it would have if it had been a signatory Lender hereunder, the Commitments shall be adjusted accordingly, and upon surrender of any Note subject to such assignment, the applicable Borrower shall execute and deliver a new Note to the assignee in an amount equal to the amount of the Revolving Credit Commitment assumed by it and a new Revolving Credit Note to the assigning Lender in an amount equal to the Revolving Credit Commitment retained by it hereunder. Any Lender which assigns any or all of its Commitment or Loans to a Person other than an Affiliate of such Lender shall pay to the Administrative Agent a service fee in the amount of $3,500 for each assignment. In the case of a participation, the participant shall only have the rights specified in Section 9.2.3 [Set-off] (the participant’s rights against such Lender in respect of such participation to be those set forth in the agreement executed by such Lender in favor of the participant relating thereto and not to include any voting rights except with respect to changes of the type referenced in Sections 11.1.1 [Increase of Commitment, Etc.], 11.1.2 [Extension of Payment, Etc.], or 11.1.3 [Release of Collateral or Guarantor]), all of such Lender’s obligations under this Agreement or any other Loan Document shall remain unchanged, and all amounts payable by any Loan Party hereunder or thereunder shall be determined as if such Lender had not sold such participation.

(ii) Any assignee or participant which is not incorporated under the Laws of the United States of America or a state thereof shall deliver to the Borrower and the Administrative Agent the form of certificate described in Section 11.17 [Tax Withholding Clause] relating to federal income tax withholding. Each Lender may furnish any publicly available information concerning any Loan Party or its Subsidiaries and any other information concerning any Loan Party or its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees or participants), provided that such assignees and participants agree to be bound by the provisions of Section 11.12 [Confidentiality].

(iii) Notwithstanding any other provision in this Agreement, any Lender may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement, its Note and the other Loan Documents to any Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or consent of the Borrower or the Administrative Agent. No such pledge or grant of a security interest shall release the transferor Lender of its obligations hereunder or under any other Loan Document.

110

11.12 Confidentiality.

11.12.1. General.

The Administrative Agent and the Lenders each agree to keep confidential all information obtained from any Loan Party or its Subsidiaries which is nonpublic and confidential or proprietary in nature (including any information the Borrower specifically designates as confidential), except as provided below, and to use such information only in connection with their respective capacities under this Agreement and for the purposes contemplated hereby. The Administrative Agent and the Lenders shall be permitted to disclose such information (i) to outside legal counsel, accountants and other professional advisors who need to know such information in connection with the administration and enforcement of this Agreement, subject to agreement of such Persons to maintain the confidentiality, (ii) to assignees and participants as contemplated by Section 11.11, and prospective assignees and participants, (iii) to the extent requested by any bank regulatory authority or, with notice to the Borrower, as otherwise required by applicable Law or by any subpoena or similar legal process, or in connection with any investigation or proceeding arising out of the transactions contemplated by this Agreement, (iv) if it becomes publicly available other than as a result of a breach of this Agreement or becomes available from a source not known to be subject to confidentiality restrictions, or (v) if the Borrower shall have consented to such disclosure. Notwithstanding anything herein to the contrary, the information subject to this Section 11.12.1 shall not include, and the Administrative Agent and each Lender may disclose without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Lender relating to such tax treatment and tax structure; provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans, Letters of Credit and transactions contemplated hereby.

11.12.2. Sharing Information With Affiliates of the Lenders.

Each Loan Party acknowledges that from time to time financial advisory, investment banking and other services may be offered or provided to the Borrower or one or more of its Affiliates (in connection with this Agreement or otherwise) by any Lender or by one or more Subsidiaries or Affiliates of such Lender and each of the Loan Parties hereby authorizes each Lender to share any information delivered to such Lender by such Loan Party and its Subsidiaries pursuant to this Agreement, or in connection with the decision of such Lender to enter into this Agreement, to any such Subsidiary or Affiliate of such Lender, it being understood that any such Subsidiary or affiliate of any Lender receiving such information shall be bound by the provisions of Section 11.12.1 as if it were a Lender hereunder. Such Authorization shall survive the repayment of the Loans and other Obligations and the termination of the Commitments.

111

11.13 Counterparts.

This Agreement may be executed by different parties hereto on any number of separate counterparts, each of which, when so executed and delivered, shall be an original, and all such counterparts shall together constitute one and the same instrument.

11.14 Agents’ or Lender’s Consent.

Whenever the Administrative Agent’s or any Lender’s consent is required to be obtained under this Agreement or any of the other Loan Documents as a condition to any action, inaction, condition or event, the Administrative Agent and each Lender shall be authorized to give or withhold such consent in its sole and absolute discretion and to condition its consent upon the giving of additional collateral, the payment of money or any other matter.

11.15 Exceptions.

The representations, warranties and covenants contained herein shall be independent of each other, and no exception to any representation, warranty or covenant shall be deemed to be an exception to any other representation, warranty or covenant contained herein unless expressly provided, nor shall any such exceptions be deemed to permit any action or omission that would be in contravention of applicable Law.

11.16 CONSENT TO FORUM; WAIVER OF JURY TRIAL.

EACH LOAN PARTY HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY AND THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO SUCH LOAN PARTY AT THE ADDRESSES PROVIDED FOR IN SECTION 11.6 AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF. EACH LOAN PARTY WAIVES ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF JURISDICTION OR VENUE. EACH LOAN PARTY, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE COLLATERAL TO THE FULL EXTENT PERMITTED BY LAW.

112

11.17 Certifications from Lenders and Participants.

11.17.1. Tax Withholding Clause.

Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and, upon the written request of the Administrative Agent, each other Lender or assignee or participant of a Lender) agrees that it will deliver to each of the Borrower and the Administrative Agent two (2) duly completed appropriate valid Withholding Certificates (as defined under § 1.1441-1(c)(16) of the Income Tax Regulations (the “Regulations”)) certifying its status (i.e. U.S. or foreign person) and, if appropriate, making a claim of reduced, or exemption from, U.S. withholding tax on the basis of an income tax treaty or an exemption provided by the Internal Revenue Code. The term “Withholding Certificate” means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form W-8IMY and the related statements and certifications as required under § 1.1441-1(e)(2) and/or (3) of the Regulations; a statement described in § 1.871-14(c)(2)(v) of the Regulations; or any other certificates under the Internal Revenue Code or Regulations that certify or establish the status of a payee or beneficial owner as a U.S. or foreign person. Each Lender, assignee or participant required to deliver to the Borrower and the Administrative Agent a Withholding Certificate pursuant to the preceding sentence shall deliver such valid Withholding Certificate as follows: (A) each Lender which is a party hereto on the Closing Date shall deliver such valid Withholding Certificate at least five (5) Business Days prior to the first date on which any interest or fees are payable by the Borrower hereunder for the account of such Lender; (B) each assignee or participant shall deliver such valid Withholding Certificate at least five (5) Business Days before the effective date of such assignment or participation (unless the Administrative Agent in its sole discretion shall permit such assignee or participant to deliver such valid Withholding Certificate less than five (5) Business Days before such date in which case it shall be due on the date specified by the Administrative Agent). Each Lender, assignee or participant which so delivers a valid Withholding Certificate further undertakes to deliver to each of the Borrower and the Administrative Agent two (2) additional copies of such Withholding Certificate (or a successor form) on or before the date that such Withholding Certificate expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent Withholding Certificate so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Administrative Agent. Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or exemption from U.S. withholding tax, the Administrative Agent shall be entitled to withhold United States federal income taxes at the full 30% withholding rate if in its reasonable judgment it is required to do so under the due diligence requirements imposed upon a withholding agent under § 1.1441-7(b) of the Regulations. Further, the Administrative Agent is indemnified under § 1.1461-1(e) of the Regulations against any claims and demands of any Lender or assignee or participant of a Lender for the amount of any tax it deducts and withholds in accordance with regulations under § 1441 of the Internal Revenue Code.

11.17.2. USA Patriot Act.

Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the

113

certification requirement contained in Section 313 of the USA Patriot Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United states or foreign county, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA Patriot Act and the applicable regulations: (1) within 10 days after the Closing Date, and (2) as such other times as are required under the USA Patriot Act.

11.18 Joinder of Guarantors.

Any Subsidiary of the Borrower which is required to join this Agreement as a Guarantor pursuant to Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures] shall execute and deliver to the Administrative Agent (i) a Guarantor Joinder in substantially the form attached hereto as Exhibit 1.1(G)(2) pursuant to which it shall join as a Guarantor each of the documents to which the Guarantors are parties; (ii) documents in the forms described in Section 7.1 [First Loans] modified as appropriate to relate to such Subsidiary; and (iii) documents necessary to grant and perfect Prior Security Interests to the Administrative Agent for the benefit of the Lenders in all Collateral held by such Subsidiary. The Loan Parties shall deliver such Guarantor Joinder and related documents to the Administrative Agent within five (5) Business Days after the date of the filing of such Subsidiary’s articles of incorporation or constitution if the Subsidiary is a corporation, the date of the filing of its certificate of limited partnership if it is a limited partnership or the date of its organization if it is an entity other than a limited partnership or corporation. The Administrative Agent and the Lenders acknowledge and agree that the guaranty agreements provided by Koppers Luxembourg and Koppers Mauritius pursuant to the Existing Credit Agreement are terminated effective as of the Closing Date.
