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

2.9.3.2 In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, the Agent will promptly notify the Borrower. Provided that it shall have received such notice, the Borrower shall reimburse (such obligation to reimburse the Agent shall sometimes be referred to as a “Reimbursement Obligation”) the Agent prior to 12:00 noon, Pittsburgh time on each date that an amount is paid by the Agent under any Letter of Credit (each such date, an “Drawing Date”) in an amount equal to the amount so paid by the Agent. In the event the Borrower fails to reimburse the Agent for the full amount of any drawing under any Letter of Credit by 12:00 noon, Pittsburgh time, on the Drawing Date, the Agent will promptly notify each Bank thereof, and the Borrower shall be deemed to have requested that Revolving Credit Loans be made by the Banks 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.

2.9.3.3 Each Bank shall upon any notice pursuant to Section 2.9.3.2 make available to the Agent an amount in immediately available funds equal to its Ratable Share of the amount of the drawing, whereupon the participating Banks shall (subject to Section 2.9.3.4) each be deemed to have made a Revolving Credit Loan under the Base Rate Option to the Borrower in that amount. If any Bank so notified fails to make available to the Agent for the account of the Agent the amount of such Bank’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 Bank’s obligation to make such payment, from the Drawing Date to the date on which such Bank 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 Loans under the Revolving Credit Base Rate Option on and after the fourth day following the Drawing Date. The Agent will promptly give notice of the occurrence of the Drawing Date, but failure of the Agent to give any such notice on the Drawing Date or in sufficient time to enable any Bank to effect such payment on such date shall not relieve such Bank from its obligation under this Section 2.9.3.3.

2.9.3.4 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 2.9.3.2, 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

- 25 -

for any other reason, the Borrower shall be deemed to have incurred from the Agent a borrowing (each a “Letter of Credit Borrowing”) 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 Bank’s payment to the Agent pursuant to Section 2.9.3.3 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 Bank in satisfaction of its participation obligation under this Section 2.9.3.

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

2.9.4.2 If the Agent is required at any time to return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the payments made by any Loan Party to the Agent pursuant to Section 2.9.4.1 in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Bank shall, on demand of the Agent, forthwith return to the Agent the amount of its Ratable Share of any amounts so returned by the Agent plus interest thereon from the date such demand is made to the date such amounts are returned by such Bank to the Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time.

2.9.5. Documentation.

Each Loan Party agrees to be bound by the terms of the Agent’s application and agreement for letters of credit and the 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, the Agent 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.

2.9.6. Determinations to Honor Drawing Requests.

In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the Agent 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.

As between any Loan Party, Bank issuer and the Agent, or the Agent’s 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, the Agent 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 the Agent or the Agent’s 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 the Agent or the Agent’s Affiliates, as applicable, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of the Agent’s or the Agent’s Affiliates rights or powers hereunder. Nothing in the preceding sentence shall relieve the Agent from liability for the Agent’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 the Agent or the Agent’s 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, the Agent and each of its Affiliates (i) may rely on any oral or other communication believed in good faith by the 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

- 29 -

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 the Agent 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 the Agent 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 (each an “Order”) 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 the Agent or the Agent’s 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 the Agent or the Agent’s Affiliates under any resulting liability to the Borrower or any Bank.

4.1.4. Rate Quotations.

The Borrower may call the 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 Agent or the Banks nor affect the rate of interest which thereafter is actually in effect when the election is made.

4.3.1. Letter of Credit Fees, Interest Rate.

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 Banks are entitled to additional compensation for such risk; and all such interest shall be payable by Borrower upon demand by Agent.

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

the Agent shall have the rights specified in Section 4.4.3.

- 34 -

(ii) such Euro-Rate Option will not adequately and fairly reflect the cost to such Bank 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 banks generally, to which a Euro-Rate Option applies, respectively, are not available to such Bank with respect to such Loan, or to banks generally, in the interbank eurodollar market,

4.4.3. Agent’s and Bank’s Rights.

In the case of any event specified in Section 4.4.1 above, the Agent shall promptly so notify the Banks and the Borrower thereof, and in the case of an event specified in Section 4.4.2 above, such Bank shall promptly so notify the Agent and endorse a certificate to such notice as to the specific circumstances of such notice, and the Agent shall promptly send copies of such notice and certificate to the other Banks 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 Banks, in the case of such notice given by the Agent, or (B) such Bank, in the case of such notice given by such Bank, to allow the Borrower to select, convert to or renew a Euro-Rate Option shall be suspended until the Agent shall have later notified the Borrower, or such Bank shall have later notified the Agent, of the Agent’s or such Bank’s, as the case may be, determination that the circumstances giving rise to such previous determination no longer exist. If at any time the Agent makes a determination under Section 4.4.1 and the Borrower has previously notified the 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 Bank notifies the Agent of a determination under Section 4.4.2, the Borrower shall, subject to the Borrower’s indemnification Obligations under Section 5.6.2 [Indemnity], as to any Loan of the Bank 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 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 Revolving Credit Base Rate Option commencing upon the last day of the existing Interest Period.

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. Except as provided in Section 4.4.3 [Agent’s and Bank’s rights], if the Borrower prepays a Loan but fails to specify the applicable Borrowing Tranche which the Borrower is prepaying, the prepayment shall be applied (i) first to Revolving Credit Loans and (ii) after giving effect to the allocations in clause (i) above first to Loans to which the Base Rate Option applies, then to Loans to which the Euro-Rate Option applies. Any prepayment hereunder shall be subject to the Borrower’s Obligation to indemnify the Banks under Section 5.6.2 [Indemnity].

5.4.2. Replacement of a Bank.

In the event any Bank (i) gives notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or Section 5.6.1 [Increased Costs, Etc.], (ii) does not fund Revolving Credit Loans because the making of such Loans would contravene any Law applicable to such Bank, or (iii) 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 Agent, which shall not be unreasonably withheld, to prepay the Loans of such Bank in whole, together with all interest accrued thereon, and terminate such Bank’s Commitment within ninety (90) days after (x) receipt of such Bank’s notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or 5.6.1 [Increased Costs, Etc.], (y) the date such Bank has failed to fund Revolving Credit Loans because the making of such Loans would contravene Law applicable to such Bank, or (z) the date such Bank became subject to the control of an Official Body, as applicable; provided that the Borrower shall also pay to such Bank 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 Bank shall be provided by one or more of the remaining Banks or a replacement bank acceptable to the Agent; provided, further, the remaining Banks shall have no obligation hereunder to increase their Commitments. Notwithstanding the foregoing, the Agent may only be replaced subject to the requirements of Section 10.14 [Successor Agent] and provided that all Letters of Credit have expired or been terminated or replaced.

5.4.3. Change of Lending Office.

Each Bank 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 Bank, it will if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Bank) 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 Bank 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 Agent or any Bank provided in this Agreement.

5.5 Reserved.

5.6 Additional Compensation in Certain Circumstances.

(i) subjects any Bank 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 Bank),

(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 Bank, 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 Bank, or (B) otherwise applicable to the obligations of any Bank 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 Bank 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 Bank’s capital, taking into consideration such Bank’s customary policies with respect to capital adequacy) by an amount which such Bank in its sole discretion deems to be material, such Bank shall from time to time notify the Borrower and the Agent of the amount determined in good faith (using any averaging and attribution methods employed in good faith) by such Bank to be necessary to compensate such Bank 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 Bank ten (10) Business Days after such notice is given.

(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 notice relating to Revolving Credit Commitment reductions under Section 2.10 [Reduction of Revolving Credit Commitment], or

(iii) default by the Borrower 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 Bank 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 Bank (which determination may include such assumptions, allocations of costs and expenses and averaging or attribution methods as such Bank shall deem reasonable) to be necessary to indemnify such Bank 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 Borrower to such Bank ten (10) Business Days after such notice is given.

(i) first, to reimburse the Agent and the Banks for out-of-pocket costs, expenses and disbursements, including reasonable attorneys’ and paralegals’ fees and legal expenses, incurred by the Agent or the Banks in connection with realizing on such assets or collection of any Obligations of any of the Loan Parties under any of the Loan Documents, including advances made by the Banks or any one of them or the Agent for the reasonable maintenance, preservation, protection or enforcement of, or realization upon, such assets, 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 such assets;

(ii) second, to the repayment of all Obligations then due and unpaid of the Loan Parties to the Banks incurred under this Agreement or any of the other Loan Documents or a Bank-Provided Interest Rate Hedge, whether of principal, interest, fees, expenses or otherwise, in such manner as the Agent may determine in its discretion; and

(iii) the balance, if any, as required by Law.

9.2.5.2 Set Off Sharing.

All rights of set off existing under any Loan Document shall secure ratably and on a pari passu basis (i) the Obligations in favor of the Agent and the Banks hereunder and (ii) the Obligations incurred by any of the Loan Parties in favor of any Bank which provides a Bank-Provided Interest Rate Hedge (the “IRH Provider”). The Agent shall be deemed to serve as the collateral agent (the “Collateral Agent”) for the IRH Provider and the

- 73 -

Banks hereunder, provided that the Collateral Agent shall comply with the instructions and directions of the Agent (or the Banks under this Agreement to the extent that this Agreement or any other Loan Documents empowers the Banks to direct the Agent), as to all matters relating to the proceeds of the exercise of such set off rights. No IRH Provider (except in its capacity as a Bank 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 such proceeds.

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 Agent shall have all of the rights and remedies available under applicable Law, all of which rights and remedies shall be cumulative and non-exclusive, to the extent permitted by Law. The Agent may, and upon the request of the Required Banks shall, exercise all post-default rights granted to the Agent and the Banks under the Loan Documents or applicable Law.

10. THE AGENT

10.1 Appointment.

Each Bank hereby irrevocably designates, appoints and authorizes PNC Bank to act as Agent for such Bank under this Agreement and to execute and deliver or accept on behalf of each of the Banks the other Loan Documents. Each Bank hereby irrevocably authorizes, and each holder of any Note by the acceptance of a Note shall be deemed irrevocably to authorize, the 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 Agent by the terms hereof, together with such powers as are reasonably incidental thereto. PNC Bank agrees to act as the Agent on behalf of the Banks to the extent provided in this Agreement.

10.2 Delegation of Duties.

The 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 Agent) and, subject to Sections 10.5 [Reimbursement of 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 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 Agent shall be

- 74 -

mechanical and administrative in nature; the Agent shall not have by reason of this Agreement a fiduciary or trust relationship in respect of any Bank; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon the 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 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 Bank expressly acknowledges (i) that the Agent has not made any representations or warranties to it and that no act by the 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 Agent to any Bank; (ii) that it has made and will continue to make, without reliance upon the 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 Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Bank 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 Agent; Instructions From the Banks.

The Agent agrees, upon the written request of the Required Banks, to take or refrain from taking any action of the type specified as being within the Agent’s rights, powers or discretion herein, provided that the Agent shall not be required to take any action which exposes the 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 Banks, the 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 Banks or all of the Banks. Any action taken or failure to act pursuant to such instructions or discretion shall be binding on the Banks, subject to Section 10.6 [Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6, no Bank shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Banks, or in the absence of such instructions, in the absolute discretion of the Agent.

10.5 Reimbursement and Indemnification of Agent by the Borrower.

The Borrower unconditionally agrees to pay or reimburse the Agent and hold the 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 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

- 75 -

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, and (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 (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 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 Agent hereunder or thereunder, provided that the Borrower shall not 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 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 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 Agent nor any of its directors, officers, employees, agents, attorneys or Affiliates shall (a) be liable to any Bank 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 Banks 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 Banks 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 Bank, the Agent or any of their respective Subsidiaries against the Agent, any Bank 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 Agent and each Bank hereby waive, releases and agree never to ▇▇▇ 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

- 76 -

favor. Each Bank agrees that, except for notices, reports and other documents expressly required to be furnished to the Banks by the Agent hereunder or given to the Agent for the account of or with copies for the Banks, the Agent and each of its directors, officers, employees, agents, attorneys or Affiliates shall not have any duty or responsibility to provide any Bank 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 Agent or any of its directors, officers, employees, agents, attorneys or Affiliates.

10.7 Reimbursement and Indemnification of Agent by Banks.

Each Bank agrees to reimburse and indemnify the 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 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 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 Agent hereunder or thereunder, provided that no Bank 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 Agent’s gross negligence or willful misconduct, or (b) if such Bank was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that such Bank shall remain liable to the extent such failure to give notice does not result in a loss to the Bank), or (c) if the same results from a compromise and settlement agreement entered into without the consent of such Bank, which shall not be unreasonably withheld. In addition, each Bank agrees promptly upon demand to reimburse the 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 Agent in connection with the Agent’s periodic audit of the Loan Parties’ books, records and business properties.

10.8 Reliance by Agent.

The 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 Agent. The 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 Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

- 77 -

10.9 Notice of Default.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Potential Default or Event of Default unless the Agent has received written notice from a Bank or the Borrower referring to this Agreement, describing such Potential Default or Event of Default and stating that such notice is a “notice of default.”

10.10 Notices.

The Agent shall promptly send to each Bank 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 Agent shall promptly notify the Borrower and the other Banks of each change in the Base Rate and the effective date thereof.

10.11 Banks in Their Individual Capacities; Agent in its Individual Capacity.

With respect to its Revolving Credit Commitment and the Revolving Credit Loans made by it and any other rights and powers given to it as a Bank hereunder or under any of the other Loan Documents, the Agent shall have the same rights and powers hereunder as any other Bank and may exercise the same as though it were not the Agent, and the term “Bank” and “Banks” shall, unless the context otherwise indicates, include the Agent in its individual capacity. PNC Bank and its Affiliates and each of the Banks 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 Agent, as though it were not acting as Agent hereunder and in the case of each Bank, as though such Bank were not a Bank hereunder, in each case without notice to or consent of the other Banks. The Banks acknowledge that, pursuant to such activities, the 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 acknowledge that the 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 Banks.

10.12 Holders of Notes.

The 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 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.

- 78 -

10.13 Equalization of Banks.

The Banks and the holders of any participations in any Notes agree among themselves that, with respect to all amounts received by any Bank or any such holder for application on any Obligation hereunder 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 Banks and such holders in proportion to their interests in payments under the Notes, except as otherwise provided in Section 4.4.3 [Agent’s and Bank’s Rights], 5.4.2 [Replacement of a Bank] or 5.6 [Additional Compensation in Certain Circumstances]. The Banks or any such holder receiving any such amount shall purchase for cash from each of the other Banks an interest in such Bank’s Loans in such amount as shall result in a ratable participation by the Banks and each such holder in the aggregate unpaid amount under the Notes, provided that if all or any portion of such excess amount is thereafter recovered from the Bank or the holder 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 Bank or the holder making such purchase.

10.14 Successor Agent.

The Agent (i) may resign as Agent or (ii) shall resign if such resignation is requested by the Required Banks (if the Agent is a Bank, the Agent’s Loans and its Commitment shall be considered in determining whether the Required Banks have requested such resignation) or required by Section 5.4.2 [Replacement of a Bank], in either case of (i) or (ii) by giving not less than thirty (30) days’ prior written notice to the Borrower. If the Agent shall resign under this Agreement, then either (a) the Required Banks shall appoint from among the Banks a successor agent for the Banks, 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 Agent’s notice to the Banks of its resignation, then the Agent shall appoint, with the consent of the Borrower, such consent not to be unreasonably withheld, a successor agent who shall serve as Agent until such time as the Required Banks 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 Agent, and the term “Agent” shall mean such successor agent, effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement. After the resignation of any Agent hereunder, the provisions of this Section 10 shall inure to the benefit of such former Agent and such former 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 Agent under this Agreement.

- 79 -

10.15 Agent’s Fee.

The Borrower shall pay to the Agent a nonrefundable fee (the “Agent’s Fee”) under the terms of a letter (the “Agent’s Letter”) between the Borrower and Agent, as amended from time to time.

10.16 Availability of Funds.

The Agent may assume that each Bank has made or will make the proceeds of a Loan available to the Agent unless the Agent shall have been notified by such Bank 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 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 Agent by the Banks and whether such funding occurs before or after the time on which Banks are required to deposit the proceeds of such Loan with the Agent). The 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 Agent by such Bank, the Agent shall be entitled to recover such amount on demand from such Bank (or, if such Bank 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 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.

10.17 Calculations.

In the absence of gross negligence or willful misconduct, the Agent shall not be liable for any error in computing the amount payable to any Bank whether in respect of the Loans, fees or any other amounts due to the Banks under this Agreement. In the event an error in computing any amount payable to any Bank is made, the Agent, the Borrower and each affected Bank 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 No Reliance on Agent’s Customer Identification Program.

Each Bank acknowledges and agrees that neither such Bank, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Bank’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

- 80 -

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.

10.19 Beneficiaries.

Except as expressly provided herein, the provisions of this Section 10 are solely for the benefit of the Agent and the Banks, 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 Agent shall act solely as agent of the Banks 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.

11. MISCELLANEOUS

11.1 Modifications, Amendments or Waivers.

With the written consent of the Required Banks, the Agent, acting on behalf of all the Banks, 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 Banks 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 Banks and the Loan Parties; provided, that, without the written consent of all the Banks, no such agreement, waiver or consent may be made which will:

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 or any mandatory Commitment reduction in connection with such a mandatory prepayment hereunder except for mandatory reductions of the Commitments on the Expiration Date), the Commitment Fee or any other fee payable to any Bank, 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 Bank, 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 Bank; or

- 81 -

11.1.3. [Reserved].

11.1.4. Miscellaneous.

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

provided, further, that no agreement, waiver or consent which would modify the interests, rights or obligations of the Agent in its capacity as Agent or as the issuer of Letters of Credit shall be effective without the written consent of the Agent.

11.2 No Implied Waivers; Cumulative Remedies; Writing Required.

No course of dealing and no delay or failure of the Agent or any Bank 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 Agent and the Banks 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 Bank 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.

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

The Borrower agrees unconditionally upon demand to pay or reimburse to each Bank (other than the Agent, as to which the Borrower’s Obligations are set forth in Section 10.5 [Reimbursement of Agent By Borrower, Etc.]) and to save such Bank 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 Bank except with respect to (a) and (b) below), incurred by such Bank (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, and (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 or bankruptcy proceedings, or (ii) all liabilities, obligations, losses, damages,

- 82 -

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 Bank, 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 Bank hereunder or thereunder, provided that the Borrower shall not 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 Bank’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 Banks will attempt to minimize the fees and expenses of legal counsel for the Banks which are subject to reimbursement by the Borrower hereunder by considering the usage of one law firm to represent the Banks and the Agent if appropriate under the circumstances. The Borrower agrees unconditionally to pay all stamp, document, transfer, recording or filing taxes or fees and similar impositions now or hereafter determined by the Agent or any Bank to be payable in connection with this Agreement or any other Loan Document, and the Borrower agrees unconditionally to save the Agent and the Banks 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.

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 Bank 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 Bank) of such Bank 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

- 83 -

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 Bank without regard to such Bank’s actual methods of making, maintaining or funding the Loans or any sources of funding actually used by or available to such Bank.

11.5.2. Actual Funding.

Each Bank shall have the right from time to time to make or maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such Bank to make or maintain such Loan subject to the last sentence of this Section 11.5.2. If any Bank 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 Bank, but in no event shall any Bank’s use of such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans hereunder cause such Bank 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 Bank (including any expenses incurred or payable pursuant to Section 5.6 [Additional Compensation in Certain Circumstances]) which would otherwise not be incurred.

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;

(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);

- 84 -

(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;

The provisions of this Agreement are intended to be severable.

(i) This Agreement shall be binding upon and shall inure to the benefit of the Banks, the Agent, the Loan Parties and their respective successors 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 Bank 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 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 Bank to an Affiliate of such Bank, and (2) any assignment by a Bank to a Person other than an Affiliate of such Bank may not be made in amounts less than the lesser of $5,000,000 or the amount of the assigning Bank’s Commitment.

Any Bank which assigns any or all of its Commitment or Loans to a Person other than an Affiliate of such Bank shall pay to the 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 Bank in respect of such participation to be those set forth in the agreement executed by such Bank 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

- 86 -

Payment, Etc.], or 11.1.3 [Release of Guarantor]), all of such Bank’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 Bank 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 Agent the form of certificate described in Section 11.17 [Tax Withholding Clause] relating to federal income tax withholding. Each Bank 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 Bank 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 Bank 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 Agent.

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.

11.17 Certifications From Banks and Participants

11.17.1. Tax Withholding.

Each Bank or assignee or participant of a Bank that is not incorporated under the Laws of the United States of America or a state thereof (and, upon the written request of the Agent, each other Bank or assignee or participant of a Bank) agrees that it will deliver to each of the Borrower and the 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 Bank, assignee or participant required to deliver to the Borrower and the Agent a Withholding Certificate pursuant to the preceding sentence shall deliver such valid Withholding Certificate as follows: (A) each Bank 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 Bank; (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 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 Agent). Each Bank, assignee or participant which so delivers

- 89 -

a valid Withholding Certificate further undertakes to deliver to each of the Borrower and the 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 Agent. Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or exemption from U.S. withholding tax, the 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 Agent is indemnified under § 1.1461-1(e) of the Regulations against any claims and demands of any Bank or assignee or participant of a Bank 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 Bank or assignee or participant of a Bank that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the 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 Bank 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] or Section 8.2.15 [Inactive Subsidiaries] shall execute and deliver to the Agent (i) a Guarantor Joinder in substantially the form attached hereto as Exhibit 1.1(G)(1) pursuant to which it shall join as a Guarantor each of the documents to which the Guarantors are parties; and (ii) documents in the forms described in Section 7.1 [First Loans] modified as appropriate to relate to such Subsidiary. If such joinder is pursuant to Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures], the Loan Parties shall deliver such Guarantor Joinder and related documents to the Agent within five (5) Business Days after the date of the filing of such Subsidiary’s articles of incorporation 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.
