If the Commitments remain in effect on the Payment Date, the Borrower shall, unless the Borrower otherwise instructs the Agent by not less than one Business Day’s prior notice, be deemed to have requested a Revolving Loan at the Base Rate in the amount of the drawing as provided in subsection (e) hereof, the proceeds of which will be used to satisfy the reimbursement obligations. The Borrower shall reimburse the applicable Issuing Lender on the Payment Date either with the proceeds of a Revolving Loan obtained hereunder or otherwise in same day funds as provided herein or in the LOC Documents. If the Borrower shall fail to reimburse the applicable Issuing Lender as provided hereinabove, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Base Rate plus two percent (2%). The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances irrespective of (but without waiver of) any rights of set-off, counterclaim or defense to payment that the applicable account party or the Borrower may claim or have against the Issuing Lenders, the Agent, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The applicable Issuing Lender will promptly notify the Lenders of the amount of any unreimbursed drawing and each Lender shall promptly pay to the Agent for the account of the applicable Issuing Lender, in Dollars and in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the applicable Issuing Lender if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 Noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the applicable Issuing Lender in full upon such request, such Lender shall, on demand, pay to the Agent for the account of the applicable Issuing Lender interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until such Lender pays such amount to the applicable Issuing Lender in full at a rate per annum equal to, if paid within two Business Days of the date of drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate. Each Lender’s obligation to make such payment to the applicable Issuing Lender, and the right of the applicable Issuing Lender to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Credit Agreement or the Commitments hereunder, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall

be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to the applicable Issuing Lender, such Lender shall, automatically and without any further action on the part of the applicable Issuing Lender or such Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the applicable Issuing Lender) in the related unreimbursed drawing portion of the LOC Obligation and in the interest thereon and in the related LOC Documents, and shall have a claim against the Borrower with respect thereto.

(e) Repayment with Revolving Loans. On any day on which the Borrower shall have requested, or been deemed to have requested, a Revolving Loan borrowing to reimburse a drawing under a Letter of Credit, the Agent shall give notice to the Lenders that a Revolving Loan has been requested or deemed requested in connection with a drawing under a Letter of Credit, in which case a Revolving Loan borrowing comprised solely of Base Rate Loans (each such borrowing, a “Mandatory Borrowing”) shall be immediately made from all Lenders (without giving effect to any termination of the Commitments pursuant to Section 9.2 or otherwise) pro rata based on each Lender’s respective Commitment Percentage and the proceeds thereof shall be paid directly to the applicable Issuing Lender for application to the respective LOC Obligations. Each such Lender hereby irrevocably agrees to make such Revolving Loans immediately upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for borrowings of Revolving Loans otherwise required hereunder, (ii) whether any conditions specified in Section 5.2 are then satisfied, (iii) whether a Default or Event of Default then exists, (iv) failure of any such request or deemed request for Revolving Loans to be made by the time otherwise required hereunder or (v) any reduction in the Revolving Committed Amount. In the event that any Mandatory Borrowing cannot be made on the date otherwise required above, whether because the Commitments have terminated or for any other reason (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code with respect to the Borrower), then each such Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Participation Interest in the outstanding LOC Obligations; provided, that in the event any Lender shall fail to fund its Participation Interest on the day it is required to do so, then the amount of such Lender’s unfunded Participation Interest therein shall bear interest payable to the applicable Issuing Lender upon demand, at the rate equal to, if paid within two Business Days of such date, the Federal Funds Rate, and thereafter at a rate equal to the Base Rate.

(f) Designation of Subsidiaries as Account Parties. Notwithstanding anything to the contrary set forth in this Credit Agreement, a Letter of Credit issued hereunder may contain a statement to the effect that such Letter of Credit is issued for the account of the Parent or any of its Subsidiaries; provided, that notwithstanding such statement, the Borrower shall be the actual account party for all purposes of this Credit Agreement for such Letter of Credit and such statement shall not affect the Borrower’s reimbursement obligations hereunder with respect to such Letter of Credit.

(g) Modification and Extension. Except for non-substantive amendments to any Letter of Credit for the purpose of correcting errors or ambiguities or to allow for administrative convenience (which amendments each Issuing Bank may make in its discretion with the consent of the Borrower), the amendment, modification, supplement, extension or renewal of any Letter of

Credit shall be deemed to be an issuance of such Letter of Credit. If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination is given by the applicable Issuing Lender, such Issuing Lender shall timely give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which such Issuing Lender’s notice of termination may be given to the beneficiaries of such Letter of Credit, such Issuing Lender has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Letter of Credit have not been satisfied or (ii) the renewed Letter of Credit would have a term not permitted by subsection (a) above.

(h) Uniform Customs and Practices. An Issuing Lender may have the Letters of Credit be subject to The Uniform Customs and Practice for Documentary Credits (the “UCP”) or the International Standby Practices 1998 (the “ISP98”), in either case as published as of the date of issue by the International Chamber of Commerce, in which case the UCP or ISP98, as applicable, may be incorporated therein and deemed in all respects to be a part thereof.

(i) Responsibility of Issuing Lenders. It is expressly understood and agreed that the obligations of each Issuing Lender hereunder to the Lenders are only those expressly set forth in this Credit Agreement and that each Issuing Lender shall be entitled to assume that the conditions precedent set forth in Section 5.2 have been satisfied unless it shall have acquired actual knowledge that any such condition precedent has not been satisfied; provided, however, that nothing set forth in this Section 2.2 shall be deemed to prejudice the right of any Lender to recover from an Issuing Lender any amounts made available by such Lender to such Issuing Lender pursuant to this Section 2.2 in the event that it is determined by a court of competent jurisdiction that the payment with respect to a Letter of Credit constituted gross negligence or willful misconduct on the part of such Issuing Lender.

(j) Conflict with LOC Documents. In the event of any conflict between this Credit Agreement and any LOC Document, this Credit Agreement shall govern.

(i) In addition to its other obligations under this Credit Agreement, the Borrower hereby agrees to protect, indemnify, pay and hold the Issuing Lenders harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees) that the Issuing Lenders may incur or be subject to as a consequence, direct or indirect, of (A) the issuance of any Letter of Credit or (B) the failure of an Issuing Lender to honor a drawing under a Letter of Credit as a result of 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 “Government Acts”).

(ii) As between the Borrower and the Issuing Lenders, the Borrower shall assume all risks of the acts, omissions or misuse of any Letter of Credit by the beneficiary thereof. The Issuing Lenders shall not be responsible for: (A) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for and issuance of any Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (B) the validity or sufficiency of any instrument transferring or

assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason; (C) failure of the beneficiary of a Letter of Credit to comply fully with conditions required in order to draw upon a Letter of Credit; (D) 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; (E) errors in interpretation of technical terms; (F) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under a Letter of Credit or of the proceeds thereof; and (G) any consequences arising from causes beyond the control of an Issuing Lender, including, without limitation, any Government Acts. None of the above shall affect, impair, or prevent the vesting of an Issuing Lender’s rights or powers hereunder.

(iii) In furtherance and extension and not in limitation of the specific provisions hereinabove set forth, any action taken or omitted by an Issuing Lender, under or in connection with any Letter of Credit or the related certificates, if taken or omitted in good faith, shall not put such Issuing Lender under any resulting liability to the Borrower. It is the intention of the parties that this Credit Agreement shall be construed and applied to protect and indemnify the Issuing Lenders against any and all risks involved in the issuance of the Letters of Credit, all of which risks are hereby assumed by the Borrower, including, without limitation, any and all risks of the acts or omissions, whether rightful or wrongful, of any present or future Government Acts. An Issuing Lender shall not, in any way, be liable for any failure by such Issuing Lender or anyone else to pay any drawing under any Letter of Credit as a result of any Government Acts or any other cause beyond the control of such Issuing Lender.

(iv) Nothing in this subsection (k) is intended to limit the reimbursement obligation of the Borrower contained in this Section 2.2. The obligations of the Borrower under this subsection (k) shall survive the termination of this Credit Agreement. No act or omission of any current or prior beneficiary of a Letter of Credit shall in any way affect or impair the rights of an Issuing Lender to enforce any right, power or benefit under this Credit Agreement.

(v) Notwithstanding anything to the contrary contained in this subsection (k) or any of the Credit Documents, the Borrower shall have no obligation to indemnify an Issuing Lender in respect of any liability incurred by such Issuing Lender arising solely out of the gross negligence or willful misconduct of such Issuing Lender, as determined by a court of competent jurisdiction. Nothing in this Credit Agreement shall relieve an Issuing Lender of any liability to the Borrower in respect of any action taken by such Issuing Lender which action constitutes gross negligence or willful misconduct of such Issuing Lender or a violation of the UCP, the ISP98 or Uniform Commercial Code (as applicable), as determined by a court of competent jurisdiction.

By no later than 11:00 a.m. (a) on the date of the requested borrowing of Loans (other than Swingline Loans) that will be Base Rate Loans or (b) three Business Days prior to the date of the requested borrowing of Loans that will be Eurodollar Loans, the Borrower shall submit a written

Notice of Borrowing in the form of Exhibit 2.3 to the Agent setting forth (i) the amount requested, (ii) whether such Loans shall accrue interest at the Adjusted Base Rate or the Adjusted Eurodollar Rate, (iii) with respect to Loans that will be Eurodollar Loans, the Interest Period applicable thereto and (iv) certification that the Borrower has complied in all respects with Section 5.2.

Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof. Each such Lender shall make its Commitment Percentage of the requested Revolving Loans or Term Loans, as applicable, available to the Agent by 2:00 p.m. on the date specified in the Notice of Borrowing by deposit, in Dollars, of immediately available funds at the Agency Services Address. The amount of the requested Loans will then be made available to the Borrower by the Agent by crediting the account of the Borrower on the books of such office of the Agent, to the extent the amount of such Loans are made available to the Agent.

No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Loans under this Section 2.4; provided, however, that the failure of any Lender to fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Loan that such Lender does not intend to make available to the Agent its portion of the Loans to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Loans, and the Agent in reliance upon such assumption, may (in its sole discretion but without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower and the Borrower shall immediately pay such corresponding amount within two Business Days to the Agent. The Agent shall also be entitled to recover from the Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to (a) from the Borrower at the applicable rate for such Loan pursuant to the Notice of Borrowing and (b) from a Lender at the Federal Funds Rate.

The Borrower shall have the option (subject to the limitations set forth below), on any Business Day, to continue existing Eurodollar Loans for a subsequent Interest Period, to convert Base Rate Loans into Eurodollar Loans or to convert Eurodollar Loans into Base Rate Loans; provided, however, that (a) each such continuation or conversion must be requested by the Borrower pursuant to a written Notice of Continuation/Conversion, in the form of Exhibit 2.5, in compliance with the terms set forth below, (b) if a Eurodollar Loan is continued or converted into a Base Rate Loan on any day other than the last day of the Interest Period applicable thereto, then the Borrower shall be subject to the provisions set forth in Section 4.3, (c) Eurodollar Loans may not be continued nor may Base Rate Loans be converted into Eurodollar Loans during the existence and continuation of a Default or Event of Default and (d) any request to extend a Eurodollar Loan that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Loan at the end of an Interest Period shall constitute a conversion to a Base Rate Loan on the last day of the

applicable Interest Period. Each continuation or conversion must be requested by the Borrower no later than 11:00 a.m. (i) on the date for a requested conversion of a Eurodollar Loan to a Base Rate Loan or (ii) three Business Days prior to the date for a requested continuation of a Eurodollar Loan or conversion of a Base Rate Loan to a Eurodollar Loan, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent which shall set forth (A) whether the Borrower wishes to continue or convert such Loans and (B) if the request is to continue a Eurodollar Loan or convert a Base Rate Loan to a Eurodollar Loan, the Interest Period applicable thereto.

Each request for a Revolving Loan or a Term Loan or a conversion or continuation hereunder shall be subject to the following requirements: (a) each Eurodollar Loan that is a Revolving Loan shall be in a minimum amount of $10,000,000 (and in integral multiples of $1,000,000 in excess thereof), (b) each Base Rate Loan that is a Revolving Loan shall be in a minimum amount of the lesser of $10,000,000 (and in integral multiples of $1,000,000 in excess thereof) or the remaining amount available to be borrowed, (c) any Term Loan shall be in a minimum amount of the lesser of $10,000,000 or the remaining amount available to be borrowed, and (d) no more than ten Eurodollar Loans shall be outstanding hereunder at any one time. For the purposes of this Section, all Eurodollar Loans with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Loan, but Eurodollar Loans with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Loans.

Upon at least five (5) Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Revolving Committed Amount at any time or from time to time; provided, that (a) each partial reduction shall be in an aggregate amount at least equal to $10,000,000 and in integral multiples of $1,000,000 above such amount, (b) no reduction shall be made which would reduce the Revolving Committed Amount to an amount less than the aggregate amount of the then outstanding Revolving Loans plus the aggregate amount of the then outstanding LOC Obligations plus the aggregate amount of then outstanding Swingline Loans. Any reduction in (or termination of) the Revolving Committed Amount shall be permanent and may not be reinstated.

(a) Swingline Commitment. Subject to the terms and conditions herein, the Swingline Lender, in its individual capacity, agrees to make loans to the Borrower in Dollars, at any time and from time to time, during the period from the Effective Date to the Maturity Date (each a “Swingline Loan” and collectively, the “Swingline Loans”); provided, however, that (i) the sum of the aggregate amount of Swingline Loans outstanding plus Revolving Loans outstanding plus LOC Obligations outstanding shall not exceed the Revolving Committed Amount, (ii) the aggregate amount of Swingline Loans outstanding at any one time shall not exceed the Swingline Committed Amount, and (iii) the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Subject to the terms and conditions of the Credit Agreement, the Borrower may borrow, repay and reborrow Swingline Loans.

(b) Notice of Borrowing and Funding. By no later than 1:00 p.m. on the date of the requested borrowing of Swingline Loans, the Borrower shall submit a written Notice of Borrowing in the form of Exhibit 2.3 to the Agent setting forth (i) the amount requested and (ii) certification that the Borrower has complied in all respects with Section 5.2. Swingline Loan borrowings shall be made in minimum amounts of $500,000 and in integral amounts of $100,000 in excess thereof. The amount of the requested Swingline Loans will then be made available to the Borrower by the Swingline Lender by crediting the account of the Borrower on the books of such office of the Agent.

(c) Repayment of Swingline Loans. The Swingline Lender may, at any time, in its sole discretion, by written notice to the Borrower, demand repayment of its Swingline Loans by way of a Revolving Loan borrowing, in which case the Borrower shall be deemed to have requested a Revolving Loan borrowing comprised entirely of Base Rate Loans in the amount of such Swingline Loans; provided, however, that, in the following circumstances, any such demand shall also be deemed to have been given one (1) Business Day prior to each of (i) the date not more than fourteen Business Days after such Swingline Loan is made, (ii) the Maturity Date, (iii) the occurrence of any Event of Default described in Section 9.1(e), (iv) upon acceleration of the Obligations hereunder, whether on account of an Event of Default described in Section 9.1(e) or any other Event of Default and (v) the exercise of remedies in accordance with the provisions of Section 9.2 hereof (each such Revolving Loan borrowing made on account of any such deemed request therefor as provided herein being hereinafter referred to as a “Mandatory Swingline Borrowing”). Each Lender hereby irrevocably agrees to make such Revolving Loans on the day such notice is received by the Lenders from the Agent if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received, in the amount and in the manner specified in the preceding sentence notwithstanding (A) the amount of the Mandatory Swingline Borrowing may not comply with the minimum amount for borrowings of Revolving Loans otherwise required hereunder, (B) whether any conditions specified in Section 5.2 are then satisfied, (C) whether a Default or an Event of Default then exists, (D) failure of any such request or deemed request for Revolving Loans to be made by the time otherwise required in Section 2.3, (E) the date of such Mandatory Swingline Borrowing, or (F) any reduction in the Revolving Committed Amount or termination of the Commitments immediately prior to such Mandatory Swingline Borrowing or contemporaneously therewith. In the event that any Mandatory Swingline Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code), then each Lender hereby agrees that it shall forthwith purchase (as of the date the Mandatory Swingline Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) from the Swingline Lender such Participation Interests in the outstanding Swingline Loans as shall be necessary to cause each such Lender to share in such Swingline Loans ratably based upon its respective Commitment Percentage (determined before giving effect to any termination of the Commitments pursuant to Section 9.2); provided that (x) all interest payable on the Swingline Loans shall be for the account of the Swingline Lender until the date as of which the respective Participation Interests is purchased, and (y) at the time any purchase of Participation Interests pursuant to this sentence is actually made, the purchasing Revolving Lender shall be required to

pay to the Swingline Lender interest on the principal amount of such Participation Interests purchased for each day from and including the day upon which the Mandatory Swingline Borrowing would otherwise have occurred to but excluding the date of payment for such participation, at the rate equal to, if paid within two (2) Business Days of the date of the Mandatory Swingline Borrowing, the Federal Funds Effective Rate, and thereafter at a rate equal to the Base Rate.

(a) The Revolving Loans made by a Lender, upon request of such Lender, shall be evidenced by a duly executed promissory note of the Borrower payable to such Lender in substantially the form of Exhibit 2.9(a) (the “Revolving Notes”).

(b) The Term Loans made by a Lender, upon request of such Lender, shall be evidenced by a duly executed promissory note of the Borrower payable to such Lender in substantially the form of Exhibit 2.9(b) (the “Term Loan Notes”).

(c) The Swingline Loans made by the Swingline Lender, upon request of the Swingline Lender, shall be evidenced by a promissory note of the Borrower payable to the Swingline Lender in substantially the form of Exhibit 2.9(c) (the “Swingline Loan Note”).

(a) Requested Increases. The Borrower shall have the right, prior to the Maturity Date and with the consent of the Agent and the Issuing Lenders (such consent not to be unreasonably withheld) with respect to the identity of any new Lender, from time to time during the term of this Credit Agreement, and subject to the terms and conditions set forth below, to increase the aggregate amount of the Revolving Committed Amount; provided that (i) no Default or Event of Default shall exist at the time of the request or the proposed increase in the Revolving Committed Amount and all conditions precedent for a Loan set forth in Section 5.2(b) and (c) have been satisfied, (ii) such increase must be in a minimum amount of $10,000,000 and in integral multiples of $1,000,000 above such amount, (iii) the Revolving Committed Amount shall not be increased to an amount greater than SEVEN HUNDRED FIFTY MILLION DOLLARS ($750,000,000) less any principal amounts outstanding under any Term Loans that by their terms automatically increase the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in Section 3.2(a)(iii), (iv) no individual Lender’s Commitment may be increased without such Lender’s written consent, (v) the Borrower shall execute and deliver such Revolving Note(s) as are necessary to reflect the increase in the Revolving Committed Amount, (vi) Schedule 1.1 shall be amended to reflect the revised Revolving Committed Amount and revised Commitments and Commitment Percentages of the Lenders and (vii) if any Revolving Loans are outstanding at the time of an increase in the Revolving Committed Amount, the Borrower will prepay (provided that any such prepayment shall be subject to Section 4.3) one or more existing Revolving Loans in an amount necessary such that after giving effect to the increase in the Revolving Committed Amount each Lender will hold its Commitment Percentage (based on its share of the revised Revolving Committed Amount) of outstanding Revolving Loans.

Any such increase in the Revolving Committed Amount shall apply, at the option of the Borrower, to (x) the Commitment of one or more existing Lenders; provided that any Lender whose Commitment is being increased must consent in writing thereto and/or (y) the creation of a new Commitment to one or more institutions that is not an existing Lender; provided that any such institution (A) must conform to the definition of Eligible Assignee, (B) must have a Commitment of at least $10,000,000 unless otherwise agreed to by the Agent and the Borrower and (C) must become a Lender under this Credit Agreement by execution and delivery of an appropriate joinder agreement or of counterparts to this Credit Agreement in a manner acceptable to the Borrower and the Agent.

(b) Automatic Increases. The Revolving Committed Amount shall, so long as no Default shall have occurred and be continuing, be automatically increased (without the consent of Lenders) and Revolving Loans made under such increased Revolving Committed Amount from time to time in order to prepay the Term Loans in accordance with Section 3.2(a)(iii). Upon any such increase, (i) each applicable Lender’s Original Revolving Commitment shall be increased automatically in accordance with its Original Revolving Commitment Percentage, (ii) Schedule 1.1 shall be amended to reflect the revised Revolving Committed Amount and the revised Commitments and, if applicable, Commitment Percentages of the Lenders and (iii) if the Borrower has previously increased the Revolving Committed Amount pursuant to Section 2.10(a) and any Revolving Loans are outstanding at the time of such increase in the Revolving Committed Amount, the Borrower will prepay (provided that any such prepayment shall be subject to Section 4.3) one or more existing Revolving Loans in an amount necessary such that after giving effect to the increase in the Revolving Committed Amount each Lender will hold its Commitment Percentage (as revised due to the increase in the Revolving Committed Amount) of outstanding Revolving Loans. For the avoidance of doubt, no Commitment or Commitment Percentage obtained by a Lender pursuant to Section 2.10(a) shall be subject to increase pursuant to this Section 2.10(b) or Section 3.2(a)(iii).

(c) Extension of Maturity Date. The Borrower may make unlimited requests for one-year extensions of the Maturity Date by delivering a written request for same to the Agent no earlier than 30 days prior to the first anniversary of the Effective Date and no later than 30 days prior to the Maturity Date (or previously extended Maturity Date pursuant hereto). Any such extension shall be effective if (i) consented to by Required Lenders within thirty (30) days after such request, (ii) on the Maturity Date as it existed immediately before such extension (A) the Commitments of the dissenting Lenders are terminated (which termination shall be effective automatically), (B) all amounts owing to such dissenting Lenders are paid in full (which payments shall not be subject to Section 3.6(a)), and (C) the total Commitments are permanently reduced by an amount equal to such dissenting Lenders’ Commitments so terminated, except to the extent that the Commitments of the dissenting Lenders are replaced pursuant to Section 2.10(a) and/or one or more Lenders agree(s) to increase their respective Commitment(s), (iii) all conditions precedent for a Loan or the issuance of a Letter of Credit set forth in Section 5.2 have been satisfied, and (iv) the Borrower does not withdraw its request for such extension before the Maturity Date (or previously extended Maturity Date pursuant hereto).

(a) The Borrower shall have the right, prior to the Maturity Date and with the consent of the Agent (such consent not to be unreasonably withheld) with respect to the identity of any new Lender, from time to time during the term of this Credit Agreement, and subject to the terms and conditions set forth below, to request additional term loans (which may or may not by their terms, at the election of the Borrower, automatically increase the aggregate amount of the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in Section 3.2(a)(iii)); provided that (i) no Default or Event of Default shall exist at the time of the request or the proposed additional term loans and all conditions precedent for a Loan set forth in Section 5.2(b), (c) and (e) have been satisfied, (ii) such increase must be in a minimum amount of $10,000,000 and in integral multiples of $1,000,000 above such amount, (iii) no such additional term loan may by its terms provide for an automatic increase in the aggregate amount of the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in Section 3.2(a)(iii), if the sum of (x) such additional term loans, plus the (y) Revolving Committed Amount, plus (z) any principal amounts outstanding under any Term Loans that by their terms automatically increase the aggregate amount of the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in Section 3.2(a)(iii), shall exceed SEVEN HUNDRED FIFTY MILLION DOLLARS ($750,000,000), (iv) no individual Lender shall be required to make any such additional term loan without such Lender’s written consent, (v) the Borrower shall execute and deliver such Term Note(s) and amendments and collateral documentation reasonably satisfactory to the Agent and provide Permitted Cash Collateral as required pursuant to Section 7.13 hereof to collateralize such additional Term Loans, and (vi) Schedule 1.1 shall be amended to reflect the revised Term Loan Amounts of the Lenders.

Any such additional term loans shall be made, at the option of the Borrower, by (x) one or more existing Lenders; provided that any Lender making such additional term loan must consent in writing thereto and/or (y) one or more institutions that is not an existing Lender; provided that any such institution (A) must conform to the definition of Eligible Assignee, (B) must have an additional term loan of at least $10,000,000 unless otherwise agreed to by the Agent and the Borrower and (C) must become a Lender under this Credit Agreement by execution and delivery of an appropriate joinder agreement or of counterparts to this Credit Agreement in a manner acceptable to the Borrower and the Agent.

(ii) All Eurodollar Loans shall accrue interest at the Adjusted Eurodollar Rate applicable to such Eurodollar Loan.

(iii) All Swingline Loans shall accrue interest at the Adjusted LIBOR Market Index Rate applicable to such Swingline Loan.

(b) Default Rate of Interest. Upon the occurrence, and during the continuation, of an Event of Default, all past due principal of and, to the extent permitted by law, past due interest on, the Loans and any other past due amounts owing hereunder or under the other Credit Documents shall bear interest, payable on demand, at a per annum rate equal to one percent (1%) plus the rate which would otherwise be applicable (or if no rate is applicable, then the rate for Loans that are Base Rate Loans plus one percent (1%) per annum).

(a) Voluntary Prepayments. The Borrower shall have the right to prepay Loans in whole or in part from time to time without premium or penalty; provided, however, that (i) Eurodollar Loans may only be prepaid on three Business Days’ prior written notice to the Agent and any prepayment of Eurodollar Loans will be subject to Section 4.3; (ii) each such partial prepayment of Revolving Loans shall be in the minimum principal amount of $10,000,000 and each such partial prepayment of Term Loans shall be in the minimum principal amount of $1,000,000; (iii) any prepayment of Term Loans that by their terms automatically increase the aggregate amount of the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in this Section 3.2(a)(iii), in connection with such a Permitted Acquisition or capital expenditure, shall, so long as no Default shall have occurred and be continuing, cause the Revolving Committed Amount to be increased in the same dollar amount of such prepayment (and Revolving Loans automatically made under such increased Revolving Committed Amount in order to make such prepayment of the Term Loans) and shall be subject to Section 2.10(b), and (iv) any prepayment of Term Loans shall be applied first (x) to Term Loans that by their terms automatically increase the aggregate amount of the Revolving Committed Amount upon any prepayment thereof in connection with a Permitted Acquisition or capital expenditure as provided in Section this 3.2(a)(iii), to be applied to such Term Loans in the order in which such Term Loans were made, and then (y) to the remaining Term Loans. Any prepayments made under this Section 3.2(a) shall be applied first to Base Rate Loans and then to Eurodollar Loans in direct order of Interest Period maturities and shall be subject to Section 4.3. The increase in the Revolving Committed Amount pursuant to this clause (a) may, upon request of the Borrower, occur concurrently with the prepayment of the Term Loans.

(b) Mandatory Prepayments. If at any time the amount of Revolving Loans outstanding plus Swingline Loans outstanding plus the aggregate amount of LOC Obligations outstanding exceeds the Revolving Committed Amount, the Borrower shall immediately make a principal payment to the Agent in a manner and in an amount necessary to be in compliance with Sections 2.1(a), 2.2 and 2.8 and as directed by the Agent. All

amounts required to be paid pursuant to this Section 3.2(b)(i) shall be (A) applied first to Swingline Loans, then to Revolving Loans (first to Base Rate Loans and then to Eurodollar Loans in the direct order of Interest Period maturities) and then to a cash collateral account in respect of LOC Obligations and (B) subject to Section 4.3.

On the Maturity Date, the entire outstanding principal balance of all Loans, together with accrued but unpaid interest and all other sums owing under this Credit Agreement, shall be due and payable in full, unless accelerated sooner pursuant to Section 9.2.

(a) Facility Fees. The Borrower shall pay to the Agent, for the pro rata benefit of the Lenders, a facility fee (the “Facility Fee”) equal to the Applicable Margin for Facility Fees times the actual daily amount of Revolving Committed Amount (or, if the Commitments have terminated, on the outstanding amount of all Revolving Loans, Swingline Loans and LOC Obligations), regardless of usage. The Facility Fee shall accrue at all times during the period beginning on the Effective Date and ending on the Maturity Date (and thereafter so long as any Revolving Loans, Swingline Loans or LOC Obligations remain outstanding), including at any time during which one or more of the conditions in Section 5.2 is not met, and shall be due and payable quarterly in arrears on the 15^th day following the last day of each calendar quarter for the prior calendar quarter, commencing with the first such date to occur after the Effective Date, and on the Maturity Date (and, if applicable, thereafter on demand). The Facility Fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Margin for Facility Fees during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Margin for Facility Fees separately for each period during such quarter that such Applicable Margin for Facility Fees was in effect.

(i) Letter of Credit Fees. In consideration of the issuance of Letters of Credit hereunder, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a per annum fee equal to the Applicable Margin for Eurodollar Loans in effect from time to time on the aggregate stated amount for each Letter of Credit from the date of issuance to the date of expiration (the “Letter of Credit Fees”). The accrued Letter of Credit Fees shall be due and payable in arrears on the 15^th day after the end of each calendar quarter of the Borrower (as well as on the Maturity Date) for the immediately preceding calendar quarter (or portion thereof), beginning with the first of such dates to occur after the Closing Date.

(ii) Issuing Lender Fees. In addition to the Letter of Credit Fees payable pursuant to subsection (i) above, the Borrower shall pay to the applicable Issuing Lender for its own account, without sharing by the other Lenders, (A) if the applicable Issuing Lender is Wachovia Bank, National Association, the fronting fee as described in the Fee Letter. or (B) if the applicable Issuing Lender is any other Lender, such other rate as may be agreed to between such Issuing

Lender and the Borrower, in each case on the total sum of all Letters of Credit issued by the applicable Issuing Lender and outstanding during the applicable period and (C) the customary charges from time to time to the applicable Issuing Lender for its services in connection with the issuance, amendment, payment, transfer, administration, cancellation and conversion of, and drawings under, such Letters of Credit (collectively, the “Issuing Lender Fees”). The accrued Issuing Lender Fees shall be due and payable in arrears on the 15^th day following the last day of each calendar quarter of the Borrower (as well as on the Maturity Date) for the immediately preceding calendar quarter (or portion thereof), beginning with the first of such dates to occur after the Closing Date.

(i) If on any day the aggregate outstanding principal amount of all Revolving Loans, Swingline Loans and LOC Obligations exceeds (A) fifty percent (50%) times (B) the Total Committed Amount, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a utilization fee equal to the Applicable Margin for Utilization Fees multiplied by the Utilized Revolving Loan Commitment (the “Utilization Fees”).

(ii) The accrued Utilization Fees shall be due and payable in arrears on the 15^th day following the last day of each calendar quarter of the Borrower for the immediately preceding calendar quarter (or portion thereof), beginning with the first of such dates to occur after the Effective Date.

(d) Administrative Fee. The Borrower agrees to pay to the Agent the annual administrative fee as described in the Fee Letter.

All payments of principal, interest, fees, expenses and other amounts to be made by the Borrower under this Credit Agreement shall be made without setoff, deduction or counterclaim and received not later than 2:00 p.m. on the date when due in Dollars and in immediately available funds by the Agent at the Agency Services Address. The Borrower shall, at the time it makes any payment under this Credit Agreement, specify to the Agent the Loans, Letters of Credit, fees or other amounts payable by the Borrower hereunder to which such payment is to be applied (and in the event that it fails to specify, or if such application would be inconsistent with the terms hereof, the Agent shall distribute such payment to the Lenders in such manner as it reasonably determines in its sole discretion). The Agent will distribute such payments to the applicable Lenders on the same Business Day if any such payment is received prior to 2:00 p.m.; otherwise the Agent will distribute each payment to the applicable Lenders prior to 12:00 noon on the next succeeding Business Day. Whenever any payment hereunder shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day (subject to accrual of interest and fees for the period of such extension), except that in the case of Eurodollar Loans, if the extension would cause the payment to be made in the next following calendar month, then such payment shall be made on the next preceding Business Day.

(a) Loans/Fees. Except to the extent otherwise provided herein, all borrowing of Revolving Loans (including each Mandatory Borrowing) and Term Loans, each payment or prepayment of principal of any Revolving Loan or Term Loan, each payment of interest on the Revolving Loans or Term Loans, each payment of Facility Fees and Utilization Fees, each payment of Letter of Credit Fees, each reduction of the Revolving Committed Amount and each conversion or continuation of any Revolving Loan or Term Loan, shall be allocated pro rata among the Lenders in accordance with their respective Commitment Percentages; provided, that, if any Lender shall have failed to pay its applicable pro rata share of any Loan, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Loan not funded by such Lender has been repaid and any interest owed by such Lender as result of such failure to fund has been paid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender shall, upon the written request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus one percent (1%) per annum.

(b) Letters of Credit. Each payment of unreimbursed drawings in respect of LOC Obligations shall be allocated to each Lender pro rata in accordance with its Commitment Percentage; provided, that, if any Lender shall have failed to pay its applicable pro rata share of any drawing under any Letter of Credit, then any amount to which such Lender would otherwise be entitled pursuant to this subsection (b) shall instead be payable to the applicable Issuing Lender; provided, further, that in the event any amount paid to any Lender pursuant to this subsection (b) is rescinded or must otherwise be returned by the applicable Issuing Lender, each Lender shall, upon the written request of the applicable Issuing Lender, repay to the Agent for the account of the applicable Issuing Lender the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the applicable Issuing Lender until the date the applicable Issuing Lender receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus one percent (1%) per annum.

(a) Except for Base Rate Loans that are based upon the Prime Rate, on which interest shall be computed on the basis of a 365 or 366 day year as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Credit Parties to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Credit Parties are hereby limited by the provisions of this paragraph which shall override and control all such agreements, whether now

existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Credit Agreement, under the Notes or otherwise, exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this paragraph and interest owing pursuant to such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value which is characterized as interest on the Loans under applicable law and which would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount which would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the Loans and not to the payment of interest, or refunded to a Credit Party or the other payor thereof if and to the extent such amount which would have been excessive exceeds such unpaid principal amount of the Loans. The right to demand payment of the Loans or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest which has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Loans shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Loans so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Loan, any unreimbursed drawing with respect to any LOC Obligations or any other obligation owing to such Lender under this Credit Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in this Credit Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Loans, LOC Obligations and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Credit Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender which shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Loan or other obligation in the amount of such participation. Except as otherwise expressly provided in this Credit Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Credit Agreement on the date when such amount is due, such payments shall accrue interest thereon, for

each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

(a) Each Lender shall maintain an account or accounts evidencing each Loan made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Credit Agreement. Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Loan hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the Register and subaccounts maintained pursuant to subsection (b) of this Section 3.9, and the entries made in the accounts maintained pursuant to subsection (a) of this Section 3.9, if consistent with the entries of the Agent, shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Loans made by such Lender in accordance with the terms hereof.

(a) Unavailability. If, on or prior to the first day of any Interest Period, (i) the Agent shall have determined in good faith (which determination shall be conclusive and binding upon the Borrower) that (A) Dollar deposits are not generally available in the London interbank Eurodollar market in the applicable principal amounts and Interest Period of a requested Eurodollar Loan or (B) by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or (ii) the Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to the Lenders of making or maintaining Eurodollar

Loans for such Interest Period (as conclusively certified by such Lenders), the Agent shall give notice thereof to the Borrower and the Lenders as soon as practicable thereafter. Upon delivery of such notice, (A) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (B) any Loans that were to have been converted to or continued as Eurodollar Loans shall be prepaid by the Borrower or converted to or continued as Base Rate Loans and (C) any outstanding Eurodollar Loans shall be converted on the date of such notice to Base Rate Loans. Until the Agent has withdrawn such notice, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Base Rate Loans to Eurodollar Loans.

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law, governmental rule, regulation, guideline or order (including the introduction of any new law or governmental rule, regulation, guideline or order) or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Loan then, by written notice to the Borrower and to the Agent, such Lender may:

(i) declare that Eurodollar Loans and conversions to or continuations of Eurodollar Loans, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Loans shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Loans, unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Loans made by it be converted to Base Rate Loans in which event all such Eurodollar Loans shall be converted to Base Rate Loans either (A) on the last day of the then current Interest Period applicable to such Eurodollar Loan if such Lender can lawfully continue to maintain and fund such Eurodollar Loan or (B) immediately if such Lender shall determine that it may not lawfully continue to maintain and fund such Eurodollar Loan to such day.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Loan or of agreeing to issue or participate in any Letters of Credit because of (i) any change after the date hereof in any law, governmental rule, regulation, guideline or order (including the introduction of any new law or governmental rule, regulation, guideline or order) or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof, including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements) or (ii) other circumstances affecting the London interbank Eurodollar market; then the Borrower shall pay to such Lender promptly upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender may determine in its sole discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder. If any Lender becomes entitled to claim any

additional amounts pursuant to this Section 4.1(c), it shall provide prompt notice thereof to the Borrower, through the Agent, certifying (A) that one of the events described in this Section 4.1(c) has occurred and describing in reasonable detail the nature of such event, (B) as to the increased cost or reduced amount resulting from such event and (C) as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof; provided, that no such amount shall be payable with respect to any period commencing more than 90 days prior to the date such Lender first notifies the Borrower of its intention to demand compensation therefor under this Section.

(d) Regulation D Compensation. In the event that a Lender is required to maintain reserves of the type contemplated by the definition of “Eurodollar Reserve Percentage”, such Lender may require the Borrower to pay, contemporaneously with each payment of interest on the Eurodollar Loans, additional interest on the related Eurodollar Loan of such Lender at a rate per annum determined by such Lender up to but not exceeding the excess of (i)(A) the applicable London Interbank Offered Rate divided by (B) one minus the Eurodollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Agent, in which case such additional interest on the Eurodollar Loans of such Lender shall be payable to such Lender at the place indicated in such notice with respect to each Interest Period commencing at least three Business Days after the giving of such notice and (y) shall notify the Borrower at least three Business Days prior to each date on which interest is payable on the Eurodollar Loans of the amount then due it under this Section. Each such notification shall be accompanied by such information as the Borrower may reasonably request.

Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Loans made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3 to the extent applicable. This Section shall survive termination of this Credit Agreement and the other Credit Documents and payment of the Loans and all other amounts payable hereunder.

If any Lender has determined that the adoption or becoming effective, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender (or its parent corporation) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender (or its parent corporation) could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s (or parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender (which shall include the basis and calculations in reasonable detail supporting the compensation requested in such notice), and receipt by the Borrower of such written notice from such Lender (with a copy to the Agent) the Borrower shall be obligated to pay to such Lender such additional amount or amounts as will compensate such Lender on an after tax

basis (after taking into account applicable deductions and credits in respect of the amount so indemnified) for such reduction; provided, that no such amount shall be payable with respect to any period commencing more than 90 days prior to the date such Lender first notifies the Borrower of its intention to demand compensation therefor under this Section. Each determination by any Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. The covenants of this Section 4.2 shall survive termination of this Credit Agreement and the other Credit Documents and the payment of the Loans and all other amounts payable hereunder.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense which such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Credit Agreement, (b) default by the Borrower in making any prepayment of a Eurodollar Loan after the Borrower has given a notice thereof in accordance with the provisions of this Credit Agreement, (c) the making of a prepayment of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto and (d) the payment, continuation or conversion of a Eurodollar Loan on a day which is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Loan when required by the terms of this Credit Agreement. Such indemnification may include an amount equal to (i) an amount of interest calculated at the Eurodollar Rate which would have accrued on the amount in question, for the period from the date of such prepayment or of such failure to borrow, convert, continue or repay to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Eurodollar Loans provided for herein minus (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurocurrency market. If any Lender becomes entitled to claim any additional amounts pursuant to this Section 4.3, it shall provide prompt notice thereof to the Borrower, through the Agent, as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof. The covenants in this Section 4.3 shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

(a) Except as provided below in this Section 4.4, all payments made by any Credit Party under this Credit Agreement and any Notes shall be made free and clear of, and without deduction or withholding for or on account of, any Non-Excluded Taxes or Other Taxes. If any such Non-Excluded Taxes or Other Taxes are required to be withheld from any amounts payable to an Agent or any Lender hereunder or under any Notes, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Credit Agreement and any Notes had no such deduction or withholding been made, provided, however, that the Credit Party shall be entitled to deduct and withhold any Non-Excluded Taxes and Other Taxes and shall not be required to increase any such

amounts payable to any Foreign Lender if such Foreign Lender fails to comply with the requirements of paragraph (c) or (d) of this Section 4.4 (but only if such Foreign Lender’s failure to comply materially prejudices such Credit Party), and (B) as promptly as possible after requested, such Credit Party shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by such Credit Party evidencing payment of any such withheld Non-Excluded or Other Taxes, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

(b) If any Credit Party fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate Governmental Authority, or fails to remit to the Agent the required receipts or other required documentary evidence, Credit Parties shall indemnify the Agent and any Lender for any incremental Non-Excluded Taxes and Other Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure, whether or not such Non-Excluded Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. The agreements in this Section 4.4 shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

(c) Any Lender, if reasonably requested in writing by the Borrower or the Agent, shall deliver such documentation as is prescribed by applicable law as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. In addition, each Foreign Lender shall:

(B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and

(C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, deliver to the Borrower and the Agent on or before the date such Foreign Lender becomes a Lender hereunder, two copies of (A) a certificate to the effect that such Foreign Lender is not (x) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (y) a “10-percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (z) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code, and (B) duly completed copies of Internal Revenue Service Form W-8BEN;

(iii) deliver to the Borrower and the Agent two further copies of Internal Revenue Service Form W-8BEN, W-8ECI, W-9 or any other such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms); and

(iv) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from or reduction of withholding with respect to payments under this Credit Agreement and any Notes.

(d) Notwithstanding the above, if any change in treaty, law or regulation (“Change in Law”) has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to subsections (c) and (d) of this Section 4.4; provided, that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to subsections (c) and (d) of this Section 4.4, shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased and, upon reasonable request by the Borrower or the Agent, such Lender shall provide a copy of all such forms and any other required forms (e.g., Internal Revenue Service Form W-8IMY) to the Borrower and the Agent.

(e) If the Agent or a Lender determines in its sole discretion that it has received a refund of any Non-Excluded Taxes or Other Taxes as to which any Credit Party has paid additional amounts pursuant to this Section 4.4, it shall pay over an amount equal to such refund to such Credit Party (but only to the extent of additional amounts paid by such Credit Party under this Section 4.4 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with

respect to such refund); provided, that such Credit Party, upon the request of the Agent or such Lender, agrees to repay the amount paid over to such Credit Party (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Agent or such Lender in the event the Agent or such Lender is required to repay such refund to such Governmental Authority. This subsection (e) shall not be construed to require the Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

The Agent and each Lender shall use reasonable efforts to avoid or mitigate any increased cost or suspension of the availability of an interest rate under Sections 4.1 through 4.4 above to the greatest extent practicable (including transferring the Loans to another lending office or Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such efforts would be likely to have an adverse effect upon it. In the event a Lender makes a request to the Borrower for additional payments in accordance with Section 4.1, 4.2 or 4.4, or suspends Eurodollar Loans under Section 4.1, or does not consent to a request to extent the Maturity Date pursuant to Section 2.10(c), or does not consent to any amendment hereto consented to by Required Lenders, then, provided that no Default or Event of Default has occurred and is continuing at such time, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4) and in its sole discretion, require such Lender to transfer and assign in whole (but not in part), without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)), all of its interests, rights and obligations under this Credit Agreement to an Eligible Assignee which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided, that (a) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (b) the Borrower or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Loans hereunder held by such assigning Lender and all other amounts owed to such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

In the event that the Borrower shall elect to make such a withdrawal, the Agent shall direct the Intermediary to liquidate the applicable Cash Collateral and remit the proceeds to the Borrower.

(d) If, at the end of any fiscal quarter of the Parent, the value of the Permitted Cash Collateral exceeds the Required Collateral Amount, then, upon the request of the Borrower, provided no Default or Event of Default has occurred and is continuing, the Agent shall direct the Intermediary to pay and transfer to the Borrower cash, to the extent available, in the Cash Collateral Account in an amount equal to such excess.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder (other than an Event of Default specified in Section 9.1(a)) unless the Agent has received notice from a Lender or the Borrower referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

Each Lender expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Agent or any Affiliate thereof hereinafter taken, including any review of the affairs of the Credit Parties, shall be deemed to constitute any representation or warranty by the Agent to any Lender. Each Lender represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets,

operations, property, financial and other conditions, prospects and creditworthiness of the Credit Parties and made its own decision to make its Extensions of Credit hereunder and enter into this Credit Agreement. Each Lender also represents that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Credit Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Credit Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, assets, property, financial or other conditions, prospects or creditworthiness of the Credit Parties which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

Each Lender agrees to indemnify the Agent (including for purposes of this Section 10.7 the Agent in its capacity as Issuing Lender) in its capacity as such (to the extent not reimbursed by the Credit Parties and without limiting the obligation of the Credit Parties to do so), ratably according to its Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including without limitation at any time following the payment in full of the Credit Parties Obligations) 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 Credit Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent. If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Obligations and all other amounts payable hereunder and under the other Credit Documents and the termination of the Commitments.

The Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with a Credit Party as though the Agent were not Agent hereunder. With respect to the Loans made, Letters of Credit issued and all Obligations owing to it, the Agent shall have the same rights and powers under this Credit Agreement as any Lender and may exercise the same as though it were not the Agent, and the terms “Lender” and “Lenders” shall include the Agent in its individual capacity.

The Agent may, at any time, resign upon 30 days written notice to the Lenders and the Borrower. Upon any such resignation, the Borrower with the consent of the Required Lenders

(such consent of the Required Lenders not to be unreasonably withheld or delayed) shall have the right to appoint a successor Agent; provided, upon the occurrence and during the continuance of an Event of Default, the Required Lenders shall have the right to appoint a successor Agent without the consent of the Borrower. If no successor Agent shall have been so appointed and shall have accepted such appointment within 30 days after the notice of resignation, then the retiring Agent shall in consultation with the Borrower, select a successor Agent provided such successor is a Lender hereunder or qualifies as an Eligible Assignee (or if no Eligible Assignee shall have been so appointed by the retiring Agent and shall have accepted such appointment, then the Lenders shall perform all obligations of the retiring Agent hereunder until such time, if any, as a successor Agent shall have been appointed and shall have accepted such appointment as provided for above). Upon the acceptance of any appointment as Agent hereunder by a successor, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations as Agent, as appropriate, under this Credit Agreement and the other Credit Documents and the provisions of this Section 10.9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Credit Agreement; provided, if such successor Agent shall have been appointed without the consent of the Borrower, such successor Agent may be replaced by the Borrower with the consent of the Required Lenders so long as no Event of Default has occurred and is continuing.

(a) Except as otherwise expressly provided herein, all notices and other communications shall have been duly given and shall be effective (i) when delivered, (ii) when transmitted via telecopy (or other facsimile device), (iii) the Business Day following the day on which the same has been delivered prepaid (or pursuant to an invoice arrangement) to a reputable national overnight air courier service, or (iv) the third Business Day following the day on which the same is sent by certified or registered mail, postage prepaid, in each case to the respective parties at the address or telecopy numbers set forth on Schedule 11.1, or at such other address as such party may specify by written notice to the other parties hereto.

(b) Notwithstanding anything herein to the contrary, notices and other communications to the Agent, the Lenders and the Credit Parties, may be delivered or furnished by electronic communication (including email, Internet or intranet website) pursuant to procedures approved by the Agent.

In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence of an Event of Default and the commencement of remedies described in Section 9.2, each Lender is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind (all of which rights being hereby expressly waived), to set-off and to appropriate and apply any and all deposits

(general or special) and any other indebtedness at any time held or owing by such Lender (including, without limitation branches, agencies or Affiliates of such Lender wherever located) to or for the credit or the account of the Borrower against obligations and liabilities of the Borrower to the Lenders hereunder, under the Notes, the other Credit Documents or otherwise, irrespective of whether the Agent or the Lenders shall have made any demand hereunder and although such obligations, liabilities or claims, or any of them, may be contingent or unmatured, and any such set-off shall be deemed to have been made immediately upon the occurrence of an Event of Default even though such charge is made or entered on the books of such Lender subsequent thereto.

(a) Generally. This Credit Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, that the Borrower may not assign and transfer any of its interests without the prior written consent of the Lenders; and provided, further, that the rights of each Lender to transfer, assign or grant participations in its rights and/or obligations hereunder shall be limited as set forth below in this Section 11.3.

(b) Assignments. Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Credit Agreement (including, without limitation, all or a portion of its Loans, its Notes, its LOC Obligations and its Commitment); provided, however, that:

(ii) all assignments of the Term Loans or the Original Revolving Committed Amount must be pro rata among such Lender’s Commitment with respect to the Term Loans and Original Revolving Committed Amount.

(iii) except in the case of an assignment to another Lender or an assignment of all of a Lender’s rights and obligations under this Credit Agreement, any such partial assignment shall be in an amount at least equal to $10,000,000 (or, if less, the remaining amount of the Commitment (which for this purpose includes Loans and LOC Obligations) being assigned by such Lender) and an integral multiple of $1,000,000 in excess thereof; and

(iv) the parties to such assignment shall execute and deliver to the Agent for its acceptance an Assignment Agreement in substantially the form of Exhibit 11.3(b), together with a processing fee from the assignor of $3,500.

Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights (except those rights hereunder which by their terms expressly survive) and be released from its obligations under this Credit Agreement. Upon the consummation of any assignment pursuant to this Section 11.3(b), the assignor, the Agent and the Borrower shall make appropriate arrangements so that, if required, new Notes are issued to the assignor and the assignee. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

By executing and delivering an assignment agreement in accordance with this Section 11.3(b), the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (A) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim created by such assigning Lender and the assignee warrants that it is an Eligible Assignee; (B) except as set forth in clause (A) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto or the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (C) such assigning Lender and such assignee represents and warrants that it is legally authorized to enter into such assignment agreement; (D) such assignee confirms that it has received a copy of this Credit Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such assignment agreement; (E) such assignee will independently and without reliance upon the Agent, such assigning Lender or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Credit Agreement and the other Credit Documents; (F) such assignee appoints and authorizes the Agent to take such action on its behalf and to exercise such powers under this Credit Agreement or any other Credit Document as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (G) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Credit Agreement and the other Credit Documents are required to be performed by it as a Lender.

(c) Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain a copy of each Assignment Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Credit Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Acceptance. Upon its receipt of an Assignment Agreement executed by the parties thereto, together with any Note subject to such assignment and payment of the processing fee, the Agent shall, if such Assignment Agreement has been completed and is in substantially the form of Exhibit 11.3(b) hereto, (i) accept such Assignment Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(e) Participations. Each Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under this Credit Agreement (including all or a portion of its Commitment, its Notes, its LOC Obligations and its Loans); provided, however, that (i) such Lender’s obligations under this Credit Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 4.1 through 4.4, inclusive, but shall not be entitled to receive any amount greater than such Lender would have been able to receive, and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Credit Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Loans, its Notes and its LOC Obligations and to approve any amendment, modification, or waiver of any provision of this Credit Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Loans or Notes, extending any scheduled principal payment date or date fixed for the payment of interest on such Loans or Notes, or extending its Commitment).

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Credit Agreement, any Lender may at any time assign and pledge all or any portion of its Loans and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

(g) Information. Subject to Section 11.17, any Lender may furnish any information concerning the Borrower in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants).

No failure or delay on the part of the Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Agent or any Lender shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies which the Agent or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent or the Lenders to any other or further action in any circumstances without notice or demand.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent in connection with (A) the negotiation, preparation, execution and delivery, syndication and administration of this Credit Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, the reasonable fees and expenses of counsel to the Agent) and (B) any amendment, waiver or consent relating hereto and thereto

including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Credit Agreement, (ii) pay all reasonable out-of-pocket costs and expenses of the Agent and each Lender in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent and each of the Lenders (including the allocated cost of internal counsel)) and (B) any bankruptcy or insolvency proceeding of any Credit Party and (iii) indemnify the Agent and each Lender, their respective Affiliates and the respective officers, directors, employees, representatives and agents of the foregoing from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Loans (including other extensions of credit) hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel and settlement costs incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified).

Neither this Credit Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower (and if the rights or duties of the Issuing Bank are affected thereby, by it); provided, that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender directly affected thereby:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal (except pursuant to Section 3.2(b)) or the time of payment of any reimbursement obligation, or any portion thereof, arising from drawings under Letters of Credit;

(b) reduce the rate or extend the time of payment of interest thereon or fees or other amounts payable hereunder to such Lender;

(c) reduce or waive the principal amount of any Loan or of any reimbursement obligation, or any portion thereof, arising from drawings under Letters of Credit owing to such Lender;

(d) increase (other than an increase to its Revolving Commitment resulting from an increase in the Revolving Committed Amount pursuant to the sale of Term Loan Cash Collateral as set forth in Section 3.2(a)(ii)) or extend the Commitment of a Lender (it being understood and agreed that a waiver of any Default or Event of Default or a waiver of any mandatory reduction in the Commitments shall not constitute a change in the terms of any Commitment of any Lender);

(e) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents or release the Borrower from its obligations under the Credit Documents, which shall require the consent of all Lenders;

(f) amend, modify or waive any provision of this Section 11.6 or Section 2.10, 3.6, 3.8, 5.2, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders;

(h) release the Cash Collateral, which shall require the consent of all Lenders, except as specifically permitted hereunder and by the Collateral Documents; or

(i) release the Parent from its obligations under the Credit Documents, which shall require the consent of all Lenders.

No provision of Section 10 may be amended or modified without the consent of the Agent.

No provision of Section 2.2 may be amended or modified without the consent of each Issuing Lender affected thereby.

No provision of Section 2.8 may be amended or modified without the consent of the Swingline Lender.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, (x) each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Loans or the Letters of Credit, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersede the unanimous consent provisions set forth herein and (y) the Required Lenders may consent to allow the Borrower to use cash collateral in the context of a bankruptcy or insolvency proceeding.

This Credit Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy or other electronic means shall be as effective as an original and shall constitute a representation that an original will be delivered.

The headings of the sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Credit Agreement.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that (a) a Lender’s Commitment may not be increased without its consent whether or not it is a Defaulting Lender and (b) all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

All indemnities set forth herein and all representations and warranties made herein shall survive the execution and delivery of this Credit Agreement, the making of the Loans, the issuance of the Letters of Credit and the repayment of the Loans, LOC Obligations and other obligations and the termination of the Commitments hereunder.

(a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. Any legal action or proceeding with respect to this Credit Agreement or any other Credit Document may be brought in the courts of the State of New York, or of the United States for the Southern District of New York, and, by execution and delivery of this Credit Agreement, the Borrower hereby irrevocably accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of such courts. The Borrower further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to it at the address for notices pursuant to Section 11.1, such service to become effective 30 days after such mailing. Nothing herein shall affect the right of a Lender to serve process in any other manner permitted by law or to commence legal proceedings or to otherwise proceed against the Borrower in any other jurisdiction.

(b) The Borrower hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Credit Agreement or any other Credit Document brought in the courts referred to in subsection (a) hereof and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY. The Borrower agrees not to assert any claim against the Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys or agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to any of the transactions contemplated hereby or by the other Credit Documents.

If any provision of any of the Credit Documents is determined to be illegal, invalid or unenforceable, such provision shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions.

The Borrower agrees, upon the request of the Agent, to promptly take such actions, as reasonably requested, as are necessary to carry out the intent of this Credit Agreement and the other Credit Documents.

This Credit Agreement together with the other Credit Documents represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Credit Documents or the transactions contemplated herein and therein.

(a) This Credit Agreement shall become effective at such time when all of the conditions set forth in Section 5.1 have been satisfied or waived by the Lenders and it shall have been executed by the Borrower, the Agent and the Lenders, and thereafter this Credit Agreement shall be binding upon and inure to the benefit of the Borrower, the Agent and each Lender and their respective successors and permitted assigns.

(b) This Credit Agreement shall be a continuing agreement and shall remain in full force and effect until all Loans, LOC Obligations, interest, fees and other Obligations have been paid in full and all Commitments and Letters of Credit have been terminated. Upon such termination, the Borrower shall have no further obligations (other than those provisions that expressly survive the termination thereof) under the Credit Documents; provided, that should any payment, in whole or in part, of the Obligations be rescinded or otherwise required to be restored or returned by the Agent or any Lender, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, then the Credit Documents shall automatically be reinstated and all amounts required to be restored or returned and all costs and expenses incurred by the Agent or any Lender in connection therewith shall be deemed included as part of the Obligations.

(a) The Agent and each Lender will keep any information delivered or made available by the Borrower pursuant to this Credit Agreement confidential from anyone other than persons employed or retained by the Agent or such Lender and its Affiliates who are engaged in evaluating, approving, structuring or administering this Credit Agreement; provided, that the Agent and the Lenders shall be entitled to disclose such information (a) to any other Lender or to the Agent, (b) upon the order of any court or administrative agency, (c) upon the request or demand of any regulatory agency or authority, (d) which had been

publicly disclosed other than as a result of a disclosure by the Agent or any Lender prohibited by this Agreement, (e) in connection with any litigation to which the Agent, any Lender or its subsidiaries or parent may be a party, (f) to the extent necessary in connection with the exercise of any remedy under this Agreement, (g) to such Lender’s or Agent’s legal counsel and independent auditors and (h) to any actual or proposed participant or assignee; provided such participant or assignee agrees in writing to keep all such information confidential on terms substantially similar to this Section 11.17.

(b) Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Patriot Act.

Parent hereby guarantees to each Lender, each Affiliate of a Lender that enters into a Credit Facility Swap Contract or a Treasury Management Agreement with a Credit Party, and the Agent as hereinafter provided, as primary obligor and not as surety, the prompt payment of the Obligations in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) strictly in accordance with the terms thereof. Parent hereby further agrees that if any of the Obligations are not paid in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise), Parent will, jointly and severally, promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Obligations, the same will be promptly paid in full when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) in accordance with the terms of such extension or renewal.

The obligations of the Parent under this Section 12.1 are absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of any of the Credit Documents, Credit Facility Swap Contracts or Treasury Management Agreements, or any other agreement or instrument referred to therein, or any substitution, release, impairment or exchange of any other guarantee of or security for any of the Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 12.2 that the obligations of the Parent hereunder shall be absolute and unconditional under any and all circumstances. The Parent agrees that it shall have no right of subrogation, indemnity, reimbursement or contribution against the Borrower for amounts paid under this Section 12 until such time as the Obligations have been paid in full and the Commitments have expired or terminated. Without limiting the generality of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the liability of the Parent hereunder, which shall remain absolute and unconditional as described above:

(a) at any time or from time to time, without notice to the Parent, the time for any performance of or compliance with any of the Obligations shall be extended, or such performance or compliance shall be waived;

(b) any of the acts mentioned in any of the provisions of any of the Credit Documents, any Credit Facility Swap Contract or Treasury Management Agreement between Credit Party and any Lender, or any Affiliate of a Lender, or any other agreement or instrument referred to in the Credit Documents, such Credit Facility Swap Contracts or such Treasury Management Agreements shall be done or omitted;

(c) the maturity of any of the Obligations shall be accelerated, or any of the Obligations shall be modified, supplemented or amended in any respect, or any right under any of the Credit Documents, any Credit Facility Swap Contract or Treasury Management Agreement between any Credit Party and any Lender, or any Affiliate of a Lender, or any other agreement or instrument referred to in the Credit Documents, such Credit Facility Swap Contracts or such Treasury Management Agreements shall be waived or any other guarantee of any of the Obligations or any security therefor shall be released, impaired or exchanged in whole or in part or otherwise dealt with;

(d) any Lien granted to, or in favor of, the Agent or any Lender or Lenders as security for any of the Obligations shall fail to attach or be perfected; or

(e) any of the Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of the Parent) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of the Parent).

With respect to its obligations hereunder, the Parent hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Agent or any Lender exhaust any right, power or remedy or proceed against any Person under any of the Credit Documents, any Credit Facility Swap Contract or any Treasury Management Agreement between any Credit Party and any Lender, or any Affiliate of a Lender, or any other agreement or instrument referred to in the Credit Documents, such Credit Facility Swap Contracts or such Treasury Management Agreements, or against any other Person under any other guarantee of, or security for, any of the Obligations.

The obligations of the Parent under this Section 12 shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and Parent agrees that it will indemnify the Agent and each Lender on demand for all reasonable costs and expenses (including, without limitation, the reasonable fees, charges and disbursements of counsel) incurred by the Agent or such Lender in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

The Parent further agrees that it shall have no right of recourse to security for the Obligations, except through the exercise of rights of subrogation pursuant to Section 12.2 and through the exercise of rights of contribution pursuant to Section 12.6.

The Parent agrees that, to the fullest extent permitted by law, as between the Parent, on the one hand, and the Agent and the Lenders, on the other hand, the Obligations may be declared to be forthwith due and payable as provided in Section 9.2 (and shall be deemed to have become automatically due and payable in the circumstances provided in said Section 9.2) for purposes of Section 12.1 notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Obligations being deemed to have become automatically due and payable), the Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by the Parent for purposes of Section 12.1. The Parent acknowledges and agrees that their obligations hereunder are secured in accordance with the terms hereof and of the Collateral Documents and that the Lenders may exercise their remedies thereunder in accordance with the terms thereof.

The guarantee in this Section 12 is a guaranty of payment and not of collection, is a continuing guarantee, and shall apply to all Obligations whenever arising. All Obligations which are incurred by two or more Credit Parties shall be their joint and several obligations and liabilities.

Each of the parties hereto has caused a counterpart of this Credit Agreement to be duly executed and delivered as of the date first above written.
