NOW, THEREFORE, in consideration of the premises and of the mutual covenants herein contained, the parties hereto agree as follows:

ARTICLE 1

DEFINITIONS; INTERPRETATION.

“Additional Commitment Amount” shall have the meaning set forth in Section 2.14(a).

“Additional Lender” shall have the meaning set forth in Section 2.14(b).

“Adjusted LIBOR” means, for any Borrowing of Eurocurrency Loans for any Interest Period, a rate per annum determined in accordance with the following formula:


Adjusted LIBOR	=	LIBOR Rate for such Interest Period
		1.00 - Statutory Reserve Rate

“Adjusted LIBOR Loan” means a Eurocurrency Loan bearing interest at a rate based on Adjusted LIBOR as provided in Section 2.6(b).

“Administrative Agent” means Citibank, N.A., acting in its capacity as administrative agent for the Lenders, and any successor Administrative Agent appointed hereunder pursuant to Section 9.7.

“Administrative Agent’s Account” means (a) in the case of Loans and Letters of Credit denominated in U.S. Dollars, the account of the Administrative Agent maintained by the Administrative Agent at its office at ▇▇▇ ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Account No. 3685 2248, Attention: Bank Loan Syndications, (b) in the case of Loans and Letters of Credit denominated in any other currency, the account of the Administrative Agent or the Sub-Agent designated in writing from time to time by the Administrative Agent to the Company and the Lenders for such purpose, and (c) in any such case, such other account of the Administrative Agent or the Sub-Agent as is designated in writing from time to time by the Administrative Agent to the Company and the Lenders for such purpose.

“Agreement” means this Revolving Credit Agreement, as the same may be amended, restated and supplemented from time to time.

A-/A3		0.065	%

BBB+/Baa1		0.080	%

The Applicable Facility Fee Rate will be determined based upon the two highest ratings issued by S&P, ▇▇▇▇▇’▇ and Fitch. If such two highest ratings differ (i) by one rating, the higher of such two highest ratings will apply to determine the Applicable Facility Fee Rate so long as the higher rating is from either S&P or Moody’s, otherwise the lower of such two highest ratings will apply, (ii) by two ratings, the rating which falls between such two highest ratings will apply to determine the Applicable Facility Fee Rate, or (iii) by more than two ratings, the rating which is one level above the lower of such two highest ratings will apply to determine the Applicable Facility Fee Rate. If only one such rating is issued by S&P, Moody’s or Fitch, the Applicable Facility Fee Rate will be determined by such rating.

BBB+/Baa1		0.320	%

BBB/Baa2		0.400	%

lower of such two highest ratings will apply to determine the Applicable Margin. If only one such rating is issued by S&P, Moody’s or Fitch, the Applicable Margin will be determined by such rating. The Company shall give written notice to the Administrative Agent of any changes to such ratings, within three (3) Business Days thereof, and any change to the Applicable Margin shall be effective on the date of the relevant change. Notwithstanding the foregoing, if the Company shall at any time fail to have in effect any such rating on the Company’s non-credit enhanced senior unsecured long-term debt, the Company shall seek and obtain (if not already in effect), within thirty (30) days after such rating first ceases to be in effect, a corporate credit rating or a bank loan rating from Fitch, ▇▇▇▇▇’▇ and/or S&P (or if none of Fitch, ▇▇▇▇▇’▇ and S&P issue such types of ratings or ratings comparable thereto, from another nationally recognized rating agency approved by each of the Company and the Administrative Agent), and the Applicable Margin shall thereafter be based on such ratings in the same manner as provided herein with respect to the Company’s non-credit enhanced senior unsecured long-term debt rating (with the Applicable Margin in effect prior to the issuance of such corporate credit rating or bank loan rating being the same as the Applicable Margin in effect at the time the non-credit enhanced senior unsecured long-term debt rating ceases to be in effect).

(a) Notice of Revolving Loan Borrowings. The Company shall give notice to the Administrative Agent by no later than (i) 12:00 P.M. at least three (3) Business Days before the date on which the Company requests the Lenders to advance a Borrowing of Eurocurrency Loans to be funded in U.S. Dollars, (ii) 12:00 P.M. at least four (4) Business Days before the date on which the Company requests the Lenders to advance a Borrowing of Eurocurrency Loans to be funded in Euros, Pounds or Canadian Dollars, (iii) 4:00 P.M. (London time) at least four (4) Business Days before the date on which the Company requests the Lenders to advance a Borrowing of Eurocurrency Loans to be funded in any Specified Currency (with a copy of any such notice to be sent simultaneously to the Sub-Agent), and (iv) 12:00 P.M. on the date the Company requests the Lenders to advance a Borrowing of Base Rate Loans, in each case pursuant to a duly completed Borrowing Request substantially in the form of Exhibit 2.3 (each a “Borrowing Request”) executed by the Company.

(b) Notice of Continuation or Conversion of Outstanding Borrowings. The Company may from time to time elect to change or continue the type of interest rate borne by each Revolving Loan Borrowing or, subject to the minimum amount requirements in Section 2.2 for each outstanding Revolving Loan Borrowing, a portion thereof, as follows: (i) if such Borrowing is of Eurocurrency Loans, the Company may continue part or all of such Borrowing as Eurocurrency Loans for an Interest Period specified by the Company or convert part or all of such Borrowing into Base Rate Loans on the last day of the Interest Period applicable thereto, or the Company may earlier convert part or all of such Borrowing into Base Rate Loans so long as it pays the breakage fees and funding losses provided in Section 2.11; and (ii) if such Borrowing is of Base Rate Loans, the Company may convert all or part of such Borrowing into Eurocurrency Loans for an Interest Period specified by the Company on any Business Day, in each case pursuant to notices of continuation or conversion as set forth below. The Company may select multiple Interest Periods for the Eurocurrency Loans constituting any such particular Borrowing, provided that at no time shall the number of different Interest Periods for outstanding Eurocurrency Loans exceed twenty (20) (it being understood for such purposes that (x) Interest Periods of the same duration, but commencing on different dates, shall be counted as different Interest Periods, and (y) all Interest Periods commencing on the same date and of the same duration shall be counted as one Interest Period regardless of the number of Borrowings or Loans involved). Notices of the continuation of such Eurocurrency Loans for an additional Interest Period or of the conversion of part or all of such Eurocurrency Loans into Base Rate Loans or of

such Base Rate Loans into Eurocurrency Loans must be given by no later than (A) 12:00 P.M. at least three (3) Business Days with respect to Eurocurrency Loans funded in U.S. Dollars, (B) 12:00 P.M. at least four (4) Business Days with respect to Eurocurrency Loans funded in Euros, Pounds or Canadian Dollars, and (C) 4:00 P.M. (London time) at least four (4) Business Days with respect to Eurocurrency Loans funded in any Specified Currency (with a copy of any such notice to be sent simultaneously to the Sub-Agent), in each case before the date of the requested continuation or conversion.

(c) Manner of Notice. The Company shall give such notices concerning the advance, continuation, or conversion of a Borrowing pursuant to this Section 2.3 by telephone or facsimile (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing) pursuant to a Borrowing Request which shall specify the date of the requested advance, continuation or conversion (which shall be a Business Day), the amount and currency of the requested Borrowing, whether such Borrowing is to be advanced, continued, or converted, the Type of Loans to comprise such new, continued or converted Borrowing, if such Borrowing is to be comprised of Eurocurrency Loans, the Interest Period applicable thereto and the applicable Borrower. The Company agrees that the Administrative Agent may rely on any such telephonic or facsimile notice given by any Person it in good faith believes is an authorized representative of the Company without the necessity of independent investigation and that, if any such notice by telephone conflicts with any written confirmation, such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon.

(d) Notice to the Lenders. The Administrative Agent shall give prompt telephonic, telex or facsimile notice to each Lender of any notice received pursuant to this Section 2.3 relating to a Revolving Loan Borrowing. The Administrative Agent shall give notice to the Company and each Lender by like means of the interest rate applicable to each Borrowing of Eurocurrency Loans (but, if such notice is given by telephone, the Administrative Agent shall confirm such rate in writing) promptly after the Administrative Agent has made such determination.

(e) Company’s Failure to Notify. If the Company fails to give notice pursuant to Section 2.3(a) or (b) of (i) the continuation or conversion of any outstanding principal amount of a Borrowing of Eurocurrency Loans, or (ii) a Borrowing of Revolving Loans to pay outstanding Reimbursement Obligations, and has not notified the Administrative Agent by (A) 12:00 P.M. at least three (3) Business Days before the last day of the Interest Period for any Borrowing of Eurocurrency Loans funded in U.S. Dollars, (B) 12:00 P.M. at least four (4) Business Days before the last day of the Interest Period for any Borrowing of Eurocurrency Loans funded in Euros, Pounds or Canadian Dollars, (C) 4:00 P.M. (London time) at least four (4) Business Days before the last day of the Interest Period for any Borrowing of Eurocurrency Loans funded in any Specified Currency (with a copy of any such notice to be sent simultaneously to the Sub-Agent), or (D) the day such Reimbursement Obligation becomes due, as the case may be, that it intends to repay such Borrowing or Reimbursement Obligation, the Company shall be deemed to have requested for such Borrower, as applicable, (x) the continuation of such Borrowing as a Eurocurrency Loan with an Interest Period of one (1) month or (y) the advance of a new Borrowing of Base Rate Loans (after converting, if necessary, the Reimbursement Obligation into Dollars using the applicable Exchange Rate in effect on such date) on such day in the amount of the Reimbursement Obligation then due, which Borrowing

pursuant to this clause (y) shall be deemed to have been funded on such date by the Lenders in accordance with Section 2.3(a) and to have been applied on such day to pay the Reimbursement Obligation then due, in each case so long as no Event of Default shall have occurred and be continuing or would occur as a result of such Borrowing but otherwise disregarding the conditions to Borrowings set forth in Section 4.2. Upon the occurrence and during the continuance of any Event of Default, and upon notice thereof from the Administrative Agent to the Company (i) each Eurocurrency Loan will automatically, on the last day of the then existing Interest Period therefor, convert into a Base Rate Loan, and (ii) the obligation of the Lenders to fund Loans in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner, and to make, continue or convert Loans into Eurocurrency Loans shall be suspended.

(f) Conversion. If the Company shall elect to convert any particular Borrowing pursuant to this Section 2.3 from one Type of Loan to the other only in part, then, from and after the date on which such conversion shall be effective, such particular Borrowing shall, for all purposes of this Agreement (including, without limitation, for purposes of subsequent application of this sentence) be deemed to instead constitute two Borrowings (each originally advanced on the same date as such particular Borrowing), one comprised of (subject to subsequent conversion in accordance with this Agreement) Eurocurrency Loans in an aggregate principal amount equal to the portion of such Borrowing so elected by the Company to be comprised of Eurocurrency Loans and the second comprised of (subject to subsequent conversion in accordance with this Agreement) Base Rate Loans in an aggregate principal amount equal to the portion of such particular Borrowing so elected by the Company to be comprised of Base Rate Loans. If the Company shall elect to have multiple Interest Periods apply to any such particular Borrowing comprised of Eurocurrency Loans, then, from and after the date such multiple Interest Periods commence, such particular Borrowing shall, for all purposes of this Agreement (including, without limitation, for purposes of subsequent application of this sentence), be deemed to constitute a number of separate Borrowings (each originally commencing on the same date as such particular Borrowing) equal to the number of, and corresponding to, the different Interest Periods so selected, each such deemed separate Borrowing corresponding to a particular selected Interest Period comprised of (subject to subsequent conversion in accordance with this Agreement) Eurocurrency Loans in an aggregate principal amount equal to the portion of such particular Borrowing so elected by the Company to have such Interest Period. This Section 2.3(f) shall be applied appropriately in the event that the Company shall make the elections described in the two preceding sentences at the same time with respect to the same particular Borrowing.

Section 2.4. Interest Periods. As provided in Section 2.3, at the time of each request for a Borrowing of Eurocurrency Loans, or for the continuation or conversion of any Borrowing of Eurocurrency Loans, the Company shall select the Interest Period(s) to be applicable to such Loans from among the available options, subject to the limitations in Section 2.3; provided, however, that:

(i) the Company may not select an Interest Period that extends beyond the Commitment Termination Date;

(ii) whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall either be (i) extended to the next

succeeding Business Day, or (ii) in the case of Eurocurrency Loans only, reduced to the immediately preceding Business Day if the next succeeding Business Day is in the next calendar month; and

(iii) for purposes of determining an Interest Period, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided, however, that if there is no such numerically corresponding day in the month in which an Interest Period is to end or if an Interest Period begins on the last Business Day of a calendar month, then in the case of Eurocurrency Loans only, such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end.

Section 2.5. Funding of Loans.

(a) Disbursement of Loans. Not later than 12:00 P.M. with respect to Borrowings in U.S. Dollars of Eurocurrency Loans, and 2:00 P.M. with respect to Base Rate Revolving Loans, on the date of any requested advance of a new Borrowing of Loans, each Lender, subject to all other provisions hereof, shall make available for the account of its applicable Lending Office its Loan comprising its portion of such Borrowing in funds immediately available for the benefit of the Administrative Agent in the applicable Administrative Agent’s Account and according to the payment instructions of the Administrative Agent. Not later than 2:00 P.M. (London time) with respect to a new Borrowing in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner, on the date of any such requested Borrowing, each Lender, subject to all other provisions hereof, shall make available its portion of such Borrowing in funds immediately available for the benefit of the Administrative Agent in the applicable Administrative Agent’s Account and according to the payment instructions of the Administrative Agent. The Administrative Agent shall promptly make the proceeds of each such Borrowing available in immediately available funds to the applicable Borrower (or as directed in writing by the Company) on such date. In the event that any Lender does not make such amounts available to the Administrative Agent by the time prescribed above, but such amount is received later that day, such amount shall nevertheless be promptly credited to the applicable Borrower in the manner described in the preceding sentence (and if such credit is made on the next Business Day, with interest on such amount to begin accruing hereunder on such next Business Day); provided that acceptance by any Borrower of any such late amount shall not be deemed a waiver by the Company of any rights it may have against such Lender. No Lender shall be responsible to any Borrower for any failure by another Lender to fund its portion of a Borrowing, and no such failure by a Lender shall relieve any other Lender from its obligation, if any, to fund its portion of a Borrowing.

(b) Administrative Agent Reliance on Lender Funding. Unless the Administrative Agent shall have been notified by a Lender prior to the time at which such Lender is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, the Administrative Agent may assume that such Lender has made such payment when due and in reliance upon such assumption may (but shall not be required to) make available to the applicable Borrower the proceeds of the Loan to be made by such Lender and, if any Lender has not in fact made such payment to the Administrative Agent, such Lender shall, on demand,

pay to the Administrative Agent the amount made available to the applicable Borrower attributable to such Lender together with interest thereon for each day during the period commencing on the date such amount was made available to the applicable Borrower and ending on (but excluding) the date such Lender pays such amount to the Administrative Agent at a rate per annum equal to the Administrative Agent’s cost of funds for such amount. If such amount is not received from such Lender by the Administrative Agent immediately upon demand, the applicable Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan, but the applicable Borrower will in no event be liable to pay any amounts otherwise due pursuant to Section 2.11 in respect of such repayment. Nothing in this subsection shall be deemed to relieve any Lender from any obligation to fund any Loans hereunder or to prejudice any rights which any Borrower may have against any Lender as a result of any default by such Lender hereunder.

Section 2.6. Applicable Interest Rates.

(a) Base Rate Loans. Each Base Rate Loan shall bear interest (computed on the basis of a 365-day year or 366-day year, as the case may be, and actual days elapsed including the first day but excluding the date of repayment) on the unpaid principal amount thereof from the date such Loan is made until maturity (whether by acceleration or otherwise) or conversion to a Eurocurrency Loan, at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the Base Rate from time to time in effect. Each Borrower agrees to pay such interest on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise).

(b) Eurocurrency Loans. Each Eurocurrency Loan shall bear interest (computed on the basis of a 360-day year and actual days elapsed, except with respect to Eurocurrency Loans funded in Pounds, in which case interest will be computed on the basis of a 365-day year or 366-day year, as the case may be, and actual days elapsed, in each case including the first day but excluding the date of repayment) on the unpaid principal amount thereof from the date such Loan is made until maturity (whether by acceleration or otherwise) or, in the case of Eurocurrency Loans, conversion to a Base Rate Loan at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the sum of Adjusted LIBOR plus the Applicable Margin. Each Borrower agrees to pay such interest on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise) or, in the case of Eurocurrency Loans, conversion to a Base Rate Loan.

(c) Swingline Loans. Each Swingline Loan shall bear interest (computed on the basis of a 365-day year or 366-day year, as the case may be, and actual days elapsed excluding the date of repayment) on the unpaid principal amount thereof from the date such Loan is made until maturity (whether by acceleration or otherwise) at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the Base Rate from time to time in effect. Each Borrower agrees to pay such interest on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise).

(d) Rate Determinations. The Administrative Agent shall determine each interest rate applicable to the Loans and Reimbursement Obligations hereunder insofar as such

interest rate involves a determination of Base Rate, Adjusted LIBOR or LIBOR Rate, or any applicable default rate pursuant to Section 2.7, and such determination shall be conclusive and binding except in the case of the Administrative Agent’s manifest error or willful misconduct. The Administrative Agent shall promptly give notice to the Company and each Lender of each determination of Adjusted LIBOR, with respect to each Eurocurrency Loan.

Section 2.7. Default Rate. If any payment of principal on any Loan is not made when due after the expiration of the grace period therefor provided in Section 7.1(a) (whether by acceleration or otherwise), or any Reimbursement Obligation is not paid when due as provided in Section 2.12(c), such past due Loan or Reimbursement Obligation shall bear interest (computed on the basis of a year of 360, 365 or 366 days, as applicable, and actual days elapsed) after any such grace period expires until such principal then due is paid in full, which each Borrower agrees to pay on demand, at a rate per annum equal to:

(a) for any Base Rate Loan or any Swingline Loan, the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at the time such payment was due);

(b) for any Eurocurrency Loan, the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period for such Loan and, thereafter, at a rate per annum equal to the sum of two percent (2%) per annum plus (x) in the case of any Loans made in Dollars, the Base Rate from time to time in effect (but not less than the Base Rate in effect at the time such payment was due), or (y) in the case of any Loans made in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroners, the interest rate that would otherwise then be applicable under this Agreement to a Eurocurrency Loan made in such currency for an Interest Period of one month as from time to time in effect (but not less than such interest rate in effect at the time such payment was due); and

(c) for any unpaid Reimbursement Obligations, the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus (x) in the case of any Reimbursement Obligations payable in Dollars, the Base Rate from time to time in effect (but not less than the Base Rate in effect at the time such payment was due), or (y) in the case of any Reimbursement Obligations payable in any currency other than Dollars, the interest rate that would otherwise then be applicable under this Agreement to a Eurocurrency Loan made in such currency for an Interest Period of one month as from time to time in effect (but not less than such interest rate in effect at the time such payment was due).

It is the intention of the Administrative Agent and the Lenders to conform strictly to usury laws applicable to them. Accordingly, if the transactions contemplated hereby or any Loan or other Obligation would be usurious as to any of the Lenders under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement, the Notes or any other Credit Document), then, in that event, notwithstanding anything to the contrary in this Agreement, the Notes or any other Credit Document, it is agreed as follows: (i) the aggregate of all consideration which constitutes

interest under laws applicable to such Lender that is contracted for, taken, reserved, charged or received by such Lender under this Agreement, the Notes or any other Credit Document or otherwise shall under no circumstances exceed the Highest Lawful Rate, and any excess shall be credited by such Lender on the principal amount of the Loans or to the Reimbursement Obligations (or, if the principal amount of the Loans and all Reimbursement Obligations shall have been paid in full, refunded by such Lender to the applicable Borrower); and (ii) in the event that the maturity of the Loans is accelerated by reason of an election of the holder or holders thereof resulting from any Event of Default hereunder or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under laws applicable to such Lender may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Agreement, the Notes, any other Credit Document or otherwise shall be automatically canceled by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Loans or to the Reimbursement Obligations (or if the principal amount of the Loans and all Reimbursement Obligations shall have been paid in full, refunded by such Lender to the applicable Borrower).

Section 2.8. Repayment of Loans; Evidence of Debt.

(a) Repayment of Loans. Each Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender, on the Commitment Termination Date, the unpaid amount of each Revolving Loan to such Borrower then outstanding. Each Borrower hereby unconditionally promises to pay to the Swingline Lender the unpaid principal amount of each Swingline Loan to such Borrower no later than the Commitment Termination Date.

(b) Record of Loans by Lenders. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan made to such Borrower by such Lender, including the amounts of principal and accrued interest payable and paid to such Lender from time to time hereunder.

(c) Record of Loans by Administrative Agent. The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or accrued interest due and payable or to become due and payable from the applicable Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) Evidence of Obligations. The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement.

(e) Notes. The Revolving Loans outstanding to each Borrower from each Lender shall, at the written request of such Lender, be evidenced by a promissory note of the applicable Borrower payable to such Lender in the form of Exhibit 2.8A (each a “Revolving Note”) or, if such Lender so requests in writing, by one or more individual promissory notes of such Borrower in similar form but payable in the specific foreign currencies in which the Loans may be funded. Each Borrower agrees to execute and deliver to the Administrative Agent, for the benefit of each Lender requesting one or more promissory notes as aforesaid, an original of each such promissory note, appropriately completed, to evidence the respective Loans made by such Lender to such Borrower hereunder, within ten (10) Business Days after the Company receives a written request therefor. The Swingline Loans outstanding to each Borrower shall be evidenced by a promissory note of each Borrower payable to the Swingline Lender in the form of Exhibit 2.8B (a “Swingline Note”).

(f) Recording of Loans and Payments on Notes. Each holder of a Note shall record on its books and records or on a schedule to its appropriate Note (and prior to any transfer of its Notes shall endorse thereon or on schedules forming a part thereof appropriate notations to evidence) the amount of each Loan outstanding from it to the maker thereof, all payments of principal and interest and the principal balance from time to time outstanding thereon, the Type of such Loan and, if a Eurocurrency Loan the Interest Period and interest rate applicable thereto. Such record, whether shown on the books and records of a holder of a Note or on a schedule to its Note, shall be prima facie evidence as to all such matters; provided, however, that the failure of any holder to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of each Borrower to repay all Loans outstanding to such Borrower hereunder together with accrued interest thereon. At the request of any holder of a Note and upon such holder tendering to the applicable Borrower the Note to be replaced, the applicable Borrower shall furnish a new Note to such holder to replace any outstanding Note and at such time the first notation appearing on the schedule on the reverse side of, or attached to, such new Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

Section 2.9. Optional Prepayments. Each Borrower shall have the privilege of prepaying any Base Rate Loans or Swingline Loans without premium or penalty at any time in whole or at any time and from time to time in part (but, if in part, then in an amount which is equal to or greater than $1,000,000); provided, however, that the Company shall have given notice of such prepayment to the Administrative Agent no later than 12:00 P.M. on the date of such prepayment. Each Borrower shall have the privilege of prepaying any Adjusted LIBOR Loans (a) without premium or penalty in whole or in part (but, if in part, then in an amount which is equal to or greater than the Dollar Equivalent of $5,000,000 and in an integral multiple of the Borrowing Multiple or such smaller amount as needed to prepay a particular Borrowing in full) only on the last Business Day of an Interest Period for such Loan, and (b) at any other time without premium or penalty except for the breakage fees and funding losses that are required to be paid pursuant to Section 2.11; provided, however, that the Company shall have given notice of such prepayment to the Administrative Agent no later than 12:00 P.M. at least three (3) Business Days before the last Business Day of such Interest Period or the proposed prepayment date (or such shorter period as may be agreed by the Administrative Agent in its sole discretion). Any such prepayments shall be made by the payment of the principal amount to be prepaid and

accrued and unpaid interest thereon to the date of such prepayment. Optional prepayments shall be applied to the Obligations then outstanding in the order specified by the Company.

Section 2.10. Mandatory Prepayments of Loans. In the event and on each occasion that the sum of the Swingline Exposure plus the Dollar Equivalent of the aggregate principal amount of outstanding Revolving Loans and L/C Obligations exceeds the Revolving Credit Commitment Amount then in effect, then the Company or the Designated Borrower, as appropriate, shall promptly prepay Revolving Loans in an aggregate amount sufficient to eliminate such excess. Immediately upon determining the need to make any such prepayment, the Company shall notify the Administrative Agent of such required prepayment and of the identity of the particular Revolving Loans being prepaid. If the Administrative Agent shall notify the Company that the Administrative Agent has determined that any prepayment is required under this Section 2.10, the Company or the Designated Borrower, as appropriate, shall make such prepayment no later than the second Business Day following such notice. Any mandatory prepayment of Revolving Loans pursuant hereto shall not be limited by the notice provision for prepayments set forth in Section 2.9. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and any applicable breakage fees and funding losses pursuant to Section 2.11.

Section 2.11. Breakage Fees. If any Lender incurs any loss, cost or expense (excluding loss of anticipated profits and other indirect or consequential damages) by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund or maintain any Eurocurrency Loan as a result of any of the following events other than any such occurrence as a result of a change of circumstance described in Sections 8.1 or 8.2:

(a) any payment, prepayment or conversion of any such Loan on a date other than the last day of its Interest Period (whether by acceleration, mandatory prepayment or otherwise);

(b) any failure to make a principal payment of any such Loan on the due date therefor; or

(c) any failure by any Borrower to borrow, continue or prepay, or convert to, any such Loan on the date specified in a notice given pursuant to Section 2.3 (other than by reason of a default of such Lender),

then the applicable Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for compensation, it shall provide to the Company a certificate executed by an officer of such Lender setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) no later than ninety (90) days after the event giving rise to the claim for compensation, and the amounts shown on such certificate shall be prima facie evidence of such Lender’s entitlement thereto. Within ten (10) days of receipt of such certificate, the applicable Borrower shall pay directly to such Lender such amount as will compensate such Lender for such loss, cost or expense as provided herein, unless such Lender has failed to timely give notice to the Company of such claim for compensation as provided herein, in which event no Borrower shall have any obligation to pay such claim.

Section 2.12. Letters of Credit.

(a) Letters of Credit. Subject to the terms and conditions hereof, each Issuing Bank agrees to issue, from time to time prior to the Commitment Termination Date, at the request of the Company and on behalf of the Lenders and in reliance on their obligations under this Section 2.12, one or more letters of credit (each a “Letter of Credit”) for the Company’s or any of its Subsidiaries’ account in a face amount in each case of at least $500,000 or, if denominated in a currency other than U.S. Dollars, the Dollar Equivalent of $500,000, and in an aggregate undrawn face amount for all Letters of Credit at any time outstanding not to exceed the Revolving Credit Commitment Amount; provided, that an Issuing Bank shall not issue or amend a Letter of Credit pursuant to this Section 2.12 if, after the issuance thereof, (i) the sum of the Swingline Exposure plus the Dollar Equivalent of the outstanding Revolving Loans and L/C Obligations would thereby exceed the Revolving Credit Commitment Amount (determined in accordance with Section 10.19) then in effect, (ii) the Dollar Equivalent of the aggregate undrawn face amount of all Letters of Credit then outstanding would at any time thereafter (giving effect to the respective scheduled expiration dates thereof and any automatic extensions provided therein) exceed the Revolving Credit Commitment Amount scheduled to be in effect at any such time thereafter (giving effect to any reductions resulting from the scheduled expiration of the Commitments of Declining Lenders not offset by new or increased Commitments of Replacement Lenders or Extending Lenders pursuant to Section 2.16), (iii) the issuance of such Letter of Credit would violate any legal or regulatory restriction then applicable to such Issuing Bank or any Lender as notified by such Issuing Bank or such Lender to the Administrative Agent before the date of issuance of such Letter of Credit or (iv) the Dollar Equivalent of the L/C Obligations would exceed $150,000,000 (the “Letter of Credit Sublimit”). Letters of Credit and any increases and extensions thereof hereunder may be issued in face amounts of either Dollars, Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner; provided further, that the Dollar Equivalent amount of the principal amount of outstanding Revolving Loans and Letters of Credit in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and Kroner determined, with respect to each such Revolving Loan or Letter of Credit, in accordance with Section 10.19 on the date such Letter of Credit is issued, increased or extended, as applicable, shall not exceed in the aggregate the Foreign Currency Sublimit.

(b) Issuance Procedure. To request that an Issuing Bank issue a Letter of Credit, the Company shall deliver to such Issuing Bank and the Administrative Agent (with a duplicate copy to an operations employee of such Issuing Bank as designated by such Issuing Bank from time to time) a duly executed Issuance Request substantially in the form of Exhibit 2.12 (each an “Issuance Request”), together with a duly executed application for the relevant Letter of Credit substantially in such Issuing Bank’s customary form or in such other form as may be approved by the Company and such Issuing Bank (each an “Application”), or such other computerized issuance or application procedure, instituted from time to time by such Issuing Bank and the Administrative Agent and agreed to by the Company, completed to the reasonable satisfaction of such Issuing Bank and the Administrative Agent, and such other information as such Issuing Bank and the Administrative Agent may reasonably request. In the event of any irreconcilable difference or inconsistency between this Agreement and an Application, the provisions of this Agreement shall govern. Upon receipt by an Issuing Bank and the Administrative Agent of a properly completed and executed Application and any other reasonably requested information at least three (3) Business Days prior to any requested issuance

date, such Issuing Bank will process such Application in accordance with its customary procedures and issue the requested Letter of Credit on the requested issuance date. The Company may cancel any requested issuance of a Letter of Credit prior to the issuance thereof. An Issuing Bank that issues a Letter of Credit will notify the Administrative Agent and each Lender of the amount, currency, and expiration date of such Letter of Credit it issues promptly upon issuance thereof. Each Letter of Credit shall have an expiration date no later than five (5) Business Days before the Commitment Termination Date. If an Issuing Bank issues any Letters of Credit with expiration dates that automatically extend unless such Issuing Bank gives notice that the expiration date will not so extend, such Issuing Bank will give such notice of non-renewal before the time necessary to prevent such automatic extension if (and will not give such notice of non-renewal before such time unless) before such required notice date (i) the expiration date of such Letter of Credit if so extended would be later than five (5) Business Days before the Commitment Termination Date, (ii) the Commitment Termination Date shall have occurred, (iii) a Default or an Event of Default exists and the Required Lenders have given such Issuing Bank instructions not to so permit the expiration date of such Letter of Credit to be extended, or (iv) such Issuing Bank is so directed by the Company; provided, however, if any Letter of Credit shall have an expiration date later than five (5) Business Days before the Commitment Termination Date, the Borrower requesting such Letter of Credit shall provide, no later than the Commitment Termination Date, cash collateral to the Administrative Agent or a back-to-back letter of credit from a bank or financial institution whose short-term unsecured debt rating is rated A or above from either S&P or ▇▇▇▇▇’▇ or such other bank or financial institution satisfactory to the applicable Issuing Banks and the Required Lenders in either case in an amount equal to the undrawn face amount of such Letter of Credit and which provides that the Administrative Agent may make a drawing thereunder in the event that the applicable Issuing Bank pays a drawing under such Letter of Credit. Each Issuing Bank that issues a Letter of Credit agrees to issue amendments to any Letter of Credit increasing its amount, or extending its expiration date, at the request of the Company, subject to the conditions precedent for all Borrowings of Section 4.2 and the other terms and conditions of this Section 2.12.

(i) The Company hereby irrevocably and unconditionally agrees to reimburse each Issuing Bank for each payment or disbursement made by such Issuing Bank to settle its obligations under any draft drawn or other payment made under a Letter of Credit (a “Reimbursement Obligation”) within two (2) Business Days from when such draft is paid or other payment is made with either funds not borrowed hereunder or with a Borrowing of Revolving Loans subject to Section 2.3 and the other terms and conditions contained in this Agreement. The Reimbursement Obligation shall bear interest (which the Company hereby promises to pay) from and after the date such draft is paid or other payment is made until (but excluding the date) the Reimbursement Obligation is paid at the lesser of (x) the Highest Lawful Rate, or (y) the Base Rate (in the case of a Letter of Credit payable in Dollars) or the rate of interest that would then be applicable hereunder to an Adjusted LIBOR Loan with an Interest Period of one month (in the case of a Letter of Credit payable in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner), in each case so long as the Reimbursement Obligation shall not be past due, and thereafter at the default rate per annum as set forth in Section 2.7(c), whether or not the Commitment Termination Date shall have occurred. If any such

payment or disbursement is reimbursed to an Issuing Bank on the date such payment or disbursement is made by such Issuing Bank, interest shall be paid on the reimbursable amount for one (1) day. An Issuing Bank that issues a Letter of Credit shall give the Company notice of any drawing on such Letter of Credit within one (1) Business Day after such drawing is paid.

(ii) The Company agrees for the benefit of each Issuing Bank and each Lender that, notwithstanding any provision of any Application, the obligations of the Company under this Section 2.12(c) and each applicable Application shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement and each applicable Application under all circumstances whatsoever (other than the defense of payment in accordance with this Agreement), including, without limitation, the following circumstances (subject in all cases to the defense of payment in accordance with this Agreement):

(1) any lack of validity or enforceability of any of the L/C Documents;

(2) any amendment or waiver of or any consent to depart from all or any of the provisions of any of the L/C Documents;

(3) the existence of any claim, set-off, defense or other right the Company may have at any time against a beneficiary of a Letter of Credit (or any person for whom a beneficiary may be acting), an Issuing Bank, any Lender or any other Person, whether in connection with this Agreement, another L/C Document or any unrelated transaction;

(4) any statement or any other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(5) payment by any Issuing Bank under a Letter of Credit against presentation to such Issuing Bank of a draft or certificate that does not comply with the terms of the Letter of Credit; or

(6) any other act or omission to act or delay of any kind by any Issuing Bank, any Lender or any other Person or any other event or circumstance whatsoever that might, but for the provisions of this Section 2.12(c), constitute a legal or equitable discharge of the Company’s obligations hereunder, under an Issuance Request or under an Application;

provided, however, the foregoing shall not be construed to excuse an Issuing Bank from liability to the Company to the extent of any direct damages (but excluding consequential damages, which are hereby waived to the extent not prohibited by applicable law) suffered by the Company that are caused by such Issuing Bank’s gross negligence or willful misconduct.

(d) The Participating Interests. Each Lender severally and not jointly agrees to purchase from each Issuing Bank, and such Issuing Bank hereby agrees to sell to each Lender,

an undivided percentage participating interest, to the extent of its Percentage, in each Letter of Credit issued by, and Reimbursement Obligation owed to, such Issuing Bank in connection with a Letter of Credit. Upon any failure by the Company to pay any Reimbursement Obligation in connection with a Letter of Credit issued by an Issuing Bank at the time required in Sections 2.12(c) and 2.3(e), or if such Issuing Bank is required at any time to return to the Company or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment by the Company of any Reimbursement Obligation in connection with a Letter of Credit, such Issuing Bank shall promptly give notice of same to each Lender, and such Issuing Bank shall have the right to require each Lender to fund its participation in such Reimbursement Obligation. Each Lender (except the Issuing Bank that issued such Letter of Credit, if it is also a Lender) shall pay to such Issuing Bank an amount equal to such Lender’s Percentage of such unpaid or recaptured Reimbursement Obligation not later than the Business Day it receives notice from such Issuing Bank to such effect, if such notice is received before 2:00 P.M., or not later than the following Business Day if such notice is received after such time. If a Lender fails to pay timely such amount to an Issuing Bank, it shall also pay to such Issuing Bank interest on such amount accrued from the date payment of such amount was made by such Issuing Bank to the date of such payment by the Lender at a rate per annum equal to the Base Rate in effect for each such day and only after such payment shall such Lender be entitled to receive its Percentage of each payment received on the relevant Reimbursement Obligation and of interest paid thereon. The several obligations of the Lenders to the Issuing Banks under this Section 2.12(d) shall be absolute, irrevocable and unconditional under any and all circumstances whatsoever and shall not be subject to any set-off, counterclaim or defense to payment any Lender may have or have had against the Company, any Issuing Bank, any other Lender or any other Person whatsoever including, but not limited to, any defense based on the failure of the demand for payment under the Letter of Credit to conform to the terms of such Letter of Credit or the legality, validity, regularity or enforceability of such Letter of Credit and INCLUDING, BUT NOT LIMITED TO, THOSE RESULTING FROM AN ISSUING BANK’S OWN SIMPLE OR CONTRIBUTORY NEGLIGENCE. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any subsequent reduction or termination of any Commitment of a Lender, and each payment by a Lender under this Section 2.12 shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Letter of Credit Amounts. Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the Dollar Equivalent of the stated amount of such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of Credit that, by its terms or the terms of any Application related thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the Dollar Equivalent of the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time.

(f) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary, the Company shall be obligated to reimburse the applicable Issuing Bank hereunder for any and all drawings under such Letter of Credit. The Company hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the

benefit of the Company, and that the Company’s business derives substantial benefits from the businesses of such Subsidiaries.

Section 2.13. Commitment Terminations. The Company shall have the right at any time and from time to time, upon three (3) Business Days’ prior and irrevocable written notice to the Administrative Agent, to terminate or reduce the Commitments or the Swingline Commitment without premium or penalty, in whole or in part, with any partial reduction (i) to be in an amount not less than $5,000,000 as determined by the Company and in integral multiples of $5,000,000 and (ii) as to the Commitments, to be allocated ratably among the Lenders in proportion to their respective Commitments; provided, that the Revolving Credit Commitment Amount may not be reduced to an amount less than the sum of the Swingline Exposure plus the Dollar Equivalent of the aggregate principal amount of outstanding Revolving Loans and L/C Obligations, after converting, if necessary, any such outstanding Obligations to their Dollar Equivalent amounts in accordance with Section 10.19 and after giving effect to payments on such proposed termination or reduction date; provided, however, that for purposes of determining the amount of L/C Obligations in the immediately preceding proviso, such L/C Obligations may be reduced on a dollar-for-dollar basis by the amount of (a) cash collateral deposited with the Administrative Agent for the purpose of securing such L/C Obligations, and (b) the face amount of back-to-back letters of credit issued in connection with one or more Letters of Credit included in such L/C Obligations by a bank(s) or financial institution(s) whose short-term unsecured debt rating is rated A or above from either S&P or ▇▇▇▇▇’▇ or such other bank(s) or financial institution(s) satisfactory to the Required Lenders with an expiration date of at least five (5) days after the expiration date of the applicable backstopped Letter of Credit and which provides that the Administrative Agent may make a drawing thereunder in the event that a drawing is made under the applicable backstopped Letter of Credit; provided further that the Revolving Credit Commitment Amount may not be reduced to an amount less than the Swingline Commitment, after giving effect to any contemporaneous reduction thereof. If, after giving effect to any reduction of the Commitments, the Foreign Currency Sublimit, the Letter of Credit Sublimit, or the Designated Borrower Sublimit exceeds the amount of the Commitments, such sublimit shall be automatically reduced by the amount of such excess. The Administrative Agent shall give prompt notice to each Lender of any such termination or reduction of the Commitments or the Swingline Commitment. Any termination of Commitments or the Swingline Commitment pursuant to this Section 2.13 is permanent and may not be reinstated.

Section 2.14. Increase of Commitments; Additional Lenders.

(a) So long as no Event of Default has occurred and is continuing, from time to time after the Initial Availability Date, the Company may, upon at least 30 days’ written notice to the Administrative Agent, elect to increase the Revolving Credit Commitment Amount in an amount such that the Revolving Credit Commitment Amount (after giving effect thereto) shall not exceed $800,000,000 at any time in effect (the amount of any such increase, the “Additional Commitment Amount”).

(b) The Company may designate one or more banks or other financial institutions (which may be, but need not be, one or more of the existing Lenders) which at the time agree to, in the case of any such Person that is an existing Lender, increase its Commitment and in the case of any other such Person (an “Additional Lender”), become a party to this

Agreement; provided, however, that any bank or financial institution that is not an existing Lender must be acceptable to the Administrative Agent, the Swingline Lender and the Issuing Banks, which acceptance will not be unreasonably withheld or delayed. The sum of the increases in the Commitments of the existing Lenders pursuant to this subsection (b) plus the Commitments of the Additional Lenders shall not in the aggregate exceed the Additional Commitment Amount. No Lender shall have any obligation whatsoever to agree to increase its Commitment.

(c) An increase in the aggregate amount of the Commitments pursuant to this Section 2.14 shall become effective upon the receipt by the Administrative Agent of a Joinder Agreement signed by the Company, by each Additional Lender and by each other Lender whose Commitment is to be increased, together with such evidence of appropriate corporate authorization on the part of the Company with respect to the increase in the Commitments and such opinions of counsel for the Company with respect to the increase in the Commitments as the Administrative Agent may reasonably request.

(d) Upon the acceptance of any such agreement by the Administrative Agent, the Revolving Credit Commitment Amount shall automatically be increased by the amount of the Commitments added through such agreement and the Commitment amounts of each Lender set forth on the signature pages hereto shall automatically be deemed to be updated.

(e) Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.14 that is not pro rata among all Lenders, (x) the Borrowers, the Administrative Agent and the Lenders shall as of the effective date of such increase make adjustments to the outstanding principal amount of Revolving Loans (but not any interest accrued thereon or any accrued fees prior to such date), including, subject to the conditions specified in Section 4.2, the borrowing of additional Revolving Loans hereunder and the repayment of Revolving Loans plus all applicable accrued interest, fees and expenses as shall be necessary to provide for Revolving Loans by the Lenders in proportion to their respective Commitments after giving effect to such increase, together with any breakage fees and funding losses that are required to be paid pursuant to Section 2.11, and each Lender shall be deemed to have made an assignment of its outstanding Revolving Loans and Commitment, and assumed outstanding Revolving Loans and Commitments of other Lenders as of the effective date of such increase as may be necessary to effect the foregoing, and (y) effective upon such increase, the amount of the unfunded participations held by each Lender in each Letter of Credit then outstanding shall be adjusted such that, after giving effect to such adjustments, the Lenders shall hold unfunded participations in each such Letter of Credit in the proportion its respective Commitment bears to the aggregate Commitments after giving effect to such increase.

Section 2.15. Additional Interest Costs.

(a) Mandatory Costs Rate. If and so long as any Lender is required to make special deposits with the Bank of England, to maintain reserve asset ratios or to pay fees, in each case in respect of such Lender’s Eurocurrency Loans in any currency other than Dollars, such Lender may require each Borrower to pay, contemporaneously with each payment of interest on each of such Loans, additional interest on such Loan at a rate per annum equal to the Mandatory

Costs Rate calculated in accordance with the formula and in the manner set forth in Exhibit 2.15 hereto.

(b) Other Requirements for Additional Interest. If and so long as any Lender is required to comply with reserve assets, liquidity, cash margin or other requirements of any monetary or other authority (including any such requirement imposed by the European Central Bank or the European System of Central Banks, but excluding requirements reflected in the Statutory Reserve Rate or the Mandatory Costs Rate) in respect of any of such Lender’s Eurocurrency Loans in any currency other than Dollars, such Lender may require each Borrower to pay, contemporaneously with each payment of interest on each of such Loans subject to such requirements, additional interest on such Loan at a rate per annum specified by such Lender to be the cost to such Lender of complying with such requirements in relation to such Loan.

(c) Determination of Amounts Due. Any additional interest owed pursuant to paragraph (a) or (b) above shall be determined by the relevant Lender and notified to the Company (with a copy to the Administrative Agent) in the form of a certificate setting forth such additional interest at least five Business Days before each date on which interest is payable for the relevant Loan, and such additional interest so notified to the Company by such Lender shall be payable to the Administrative Agent for the account of such Lender on each date on which interest is payable for such Loan.

(d) Limitation on Amounts Due. Subject to the provisions of Section 8.3(c), failure or delay on the part of any Lender on any occasion to demand additional interest pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such additional interest on any subsequent occasion.

Section 2.16. Extensions of Commitment Termination Date. So long as no Event of Default has occurred and is continuing, no earlier than 60 days and at least 45 days prior to any anniversary of the Effective Date, the Company may (but in no event on more than two occasions during the term of this Agreement), by written notice to the Administrative Agent, request that the Commitment Termination Date then in effect be extended for a 1-year period. On each such occasion, the Administrative Agent shall promptly notify each Lender of such request. If a Lender agrees, in its individual and sole discretion, to so extend its Commitment (an “Extending Lender”), it shall deliver to the Administrative Agent a written notice of its agreement to do so no earlier than 30 days prior to such anniversary date and the Administrative Agent shall promptly thereafter notify the Company of such Extending Lender’s agreement to extend its Commitment (and such agreement shall be irrevocable until such anniversary date). The Commitment of any Lender that fails to accept or respond to the Company’s request for extension of the Commitment Termination Date (a “Declining Lender”) shall be terminated on the Commitment Termination Date then in effect for such Lender (without regard to any extension by other Lenders) and on such Commitment Termination Date the Borrowers shall pay in full the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees, including, without limitation, fees under Section 2.11, accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Declining Lender under this Agreement. The Administrative Agent shall promptly notify each Extending Lender of the aggregate Commitments of the Declining Lenders. Each Extending Lender may

offer to increase its respective Commitment by an aggregate amount up to the aggregate amount of the Declining Lenders’ Commitments and such Extending Lender shall deliver to the Administrative Agent a notice of its offer to so increase its Commitment no later than 15 days prior to such anniversary date (and such offer shall be irrevocable until such anniversary date). To the extent the aggregate amount of extended Commitments is less than the aggregate amount of Commitments so requested to be extended pursuant to the foregoing, the Company shall have the right to require any Declining Lender at any time thereafter to (and any such Declining Lender shall) assign in full its rights and obligations under this Agreement to one or more banks or other financial institutions (which may be, but need not be, one or more of the existing Lenders) which at the time agree to, in the case of any such Person that is an existing Lender, increase its Commitment and in the case of any other such Person (a “Replacement Lender”) become a party to this Agreement; provided that (i) such assignment is otherwise in compliance with Section 10.10(b), and (ii) such Declining Lender receives payment in full of the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Declining Lender under this Agreement. If, but only if, Extending Lenders and Replacement Lenders have agreed to provide Commitments in an aggregate amount greater than 50% of the aggregate amount of the Commitments outstanding immediately prior to such anniversary date, the Commitment Termination Date of such Extending Lenders and Replacement Lenders shall be extended by one year effective as of such anniversary of the Effective Date.

Section 2.17. Swingline Advances. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans in Dollars to the Borrowers from time to time prior to the Commitment Termination Date, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding the Swingline Commitment or (ii) the sum of the aggregate Swingline Exposure plus the Dollar Equivalent of the aggregate principal amount of the Revolving Loans plus the L/C Obligations of all Lenders (determined in accordance with Section 10.19) exceeding the Revolving Credit Commitment Amount then in effect; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, each Borrower may borrow, repay and reborrow Swingline Loans.

(b) To request a Swingline Loan, Company shall deliver, by hand delivery or telecopier, a duly completed and executed Swingline Loan Request substantially in the form of Exhibit 2.17 (each a “Swingline Request”) to the Administrative Agent and the Swingline Lender, not later than 2:00 p.m., on the day of a proposed Swingline Loan. Each such Swingline Request shall be irrevocable and shall specify the requested date (which shall be a Business Day), the amount of the requested Swingline Loan and the applicable Borrower. The Swingline Lender shall make each Swingline Loan available to the applicable Borrower to an account as directed in writing by Company in the applicable Swingline Request maintained with the Administrative Agent by 3:00 p.m. on the requested date of such Swingline Loan. Company shall not request a Swingline Loan if at the time of or immediately after giving effect to such Swingline Loan a Default or Event of Default has occurred and is continuing or would result therefrom. The Swingline Lender shall not make a Swingline Loan if it has received notice from

Borrower or any Lender that a Default or Event of Default exists or would result from such Swingline Loan. Swingline Loans shall be made in minimum amounts of $2,500,000 and integral multiples of $100,000 above such amount.

(c) Each Borrower shall have the right at any time and from time to time to repay any Swingline Loan, in whole or in part, upon giving written notice to the Swingline Lender and the Administrative Agent before 12:00 noon on the proposed date of repayment.

(d) The Swingline Lender may at any time in its discretion by written notice given to the Administrative Agent (provided such notice requirement shall not apply if the Swingline Lender and the Administrative Agent are the same entity) not later than 11:00 a.m. on the next succeeding Business Day following such notice require the Revolving Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans then outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent, or if the Swingline Lender and the Administrative Agent are the same entity, the Swingline Lender, will give notice thereof to each Lender, specifying in such notice such Lender’s applicable Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or Event of Default or reduction or termination of the Revolving Credit Commitment Amount and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.5(a) with respect to Loans made by such Lender, and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Company of any participations in any Swingline Loan acquired by the Revolving Lenders pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from any Borrower (or other party on behalf of any Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent. Any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph, as their interests may appear. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrowers of any default in the payment thereof.

Section 2.18. Designated Borrowers.

(a) The Company may at any time, upon not less than fifteen (15) Business Days’ notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), designate the Designated Borrower to receive Loans hereunder by delivering to the Administrative Agent (which shall promptly deliver counterparts thereof to each Lender) a duly executed notice and agreement in substantially the

form of Exhibit 2.18A (a “Designated Borrower Request and Assumption Agreement”). Following the giving of any notice pursuant to this Section 2.18(a), if the designation of such Designated Borrower obligates the Administrative Agent or any Lender to comply with “know your customer” or similar identification procedures in circumstances where the necessary information is not already available to it, the Company shall, promptly upon the request of the Administrative Agent or any Lender, supply such documentation and other evidence as is reasonably requested by the Administrative Agent or any Lender in order for the Administrative Agent or such Lender to carry out and be satisfied it has complied with the results of all necessary “know your customer” or other similar checks under all applicable laws and regulations.

(b) Within five (5) Business Days after receiving notice from the Company or the Administrative Agent of the Company’s intent to designate a Subsidiary as a Designated Borrower for a Designated Borrower that is organized under the laws of a jurisdiction other than of the United States or a political subdivision thereof, any Lender that may not legally lend to, establish credit for the account of and/or do any business whatsoever with such Designated Borrower directly or through an Affiliate of such Lender as provided in the immediately preceding paragraph (a “Protesting Lender”) shall so notify the Company and the Administrative Agent in writing. With respect to each Protesting Lender, the Company shall, effective on or before the date that such Designated Borrower shall have the right to borrow hereunder, (A) notify the Administrative Agent and such Protesting Lender that the Commitments of such Protesting Lender shall be terminated and either (1) the Borrowers shall pay in full the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to such Protesting Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Protesting Lender under this Agreement, or (2) the Company shall have the right to require any Protesting Lender at any time thereafter to (and any such Protesting Lender shall) assign in full its rights and obligations under this Agreement to one or more banks or other financial institutions (which may be, but need not be, one or more existing Lenders) which at the time agree to, in the case of any such Person that is an existing Lender, increase its Commitment and in the case of any other Person become a party to this Agreement; provided that (x) such assignment is otherwise in compliance with Section 10.10(b), and (y) such Protesting Lender receives payment in full of the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to such Protesting Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Protesting Lender under this Agreement; or (B) cancel its request to designate such Subsidiary as a “Designated Borrower” hereunder.

(c) The parties hereto acknowledge and agree that prior to the Designated Borrower becoming entitled to utilize the Revolving Credit provided for herein, the Administrative Agent and the Lenders shall have received the duly executed Company Guaranty, together with such supporting resolutions, incumbency certificates, opinions of counsel and other documents or information, in form, content and scope reasonably satisfactory to the Administrative Agent, as may be required by the Administrative Agent or the Required Lenders, and Notes signed by the Designated Borrower to the extent any Lenders so require. Promptly following receipt of the Company Guaranty and all such requested resolutions, incumbency certificates, opinions of counsel and other documents or information, the Administrative Agent

shall send a notice in substantially the form of Exhibit 2.18B (a “Designated Borrower Notice”) to the Company and the Lenders specifying the effective date upon which the Designated Borrower shall constitute a Borrower for purposes hereof, whereupon each of the Lenders agrees to permit such Designated Borrower to receive Loans hereunder, on the terms and conditions set forth herein, and each of the parties agrees that such Designated Borrower otherwise shall be a Borrower for all purposes of this Agreement.

(d) The Obligations of the Designated Borrower shall be guaranteed by the Company pursuant to the Company Guaranty.

(e) The Designated Borrower hereby irrevocably appoints the Company as its agent for all purposes relevant to this Agreement and each of the other Credit Documents, including (i) the giving and receipt of notices, (ii) the execution and delivery of all documents, instruments and certificates contemplated herein and all modifications hereto, and (iii) the receipt of the proceeds of any Loans made by the Lenders, to any such Designated Borrower hereunder. Any acknowledgment, consent, direction, certification or other action which might otherwise be valid or effective only if given or taken by all Borrowers, or by each Borrower acting singly, shall be valid and effective if given or taken only by the Company, whether or not any such other Borrower joins therein. Any notice, demand, consent, acknowledgement, direction, certification or other communication delivered to the Company in accordance with the terms of this Agreement shall be deemed to have been delivered to each Designated Borrower.

(f) The Company may from time to time, upon not less than 15 Business Days’ notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), terminate a Designated Borrower’s status as such, provided that there are no outstanding Loans payable by such Designated Borrower, or other amounts payable by such Designated Borrower on account of any Loans made to it, as of the effective date of such termination. The Administrative Agent will promptly notify the Lenders of any such termination of a Designated Borrower’s status.

ARTICLE 3

FEES AND PAYMENTS.

Section 3.1. Fees.

(a) Facility Fees. The Company agrees to pay to the Administrative Agent for the account of each Lender a facility fee, which shall accrue at the Applicable Facility Fee Rate on the daily amount of the Commitment of such Lender (whether used or unused) during the period from and including the Initial Availability Date to but excluding the date on which such Commitment terminates; provided that, if such Lender continues to have any Revolving Credit Exposure or Swingline Exposure after its Commitment terminates, then such facility fee shall continue to accrue on the daily amount of the sum of such Lender’s Revolving Credit Exposure plus such Lender’s Swingline Exposure from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Revolving Credit Exposure and Swingline Exposure. Accrued facility fees shall be payable in arrears on the last Business Day of March, June, September and December of each year, commencing on March 31,

2007, on the date(s) on which the Commitments shall have terminated and the Lenders shall have no further Revolving Credit Exposures, and on the Maturity Date. All facility fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) Utilization Fees. For any day prior to the Commitment Termination Date on which the Dollar Equivalent of the outstanding principal amount of the Loans and L/C Obligations shall be greater than or equal to an amount equal to 50% of the total Commitments (and for any day after the termination of all the Commitments on which any Loans or L/C Obligations shall be outstanding if the Dollar Equivalent of the outstanding principal amount thereof on the date the Commitments terminated shall have been greater than or equal to 50% of the total Commitments in effect on such date) the Company shall pay to the Administrative Agent for the account of each Lender a utilization fee equal to the Applicable Utilization Fee Rate multiplied by the Dollar Equivalent of aggregate amount of such Lender’s outstanding Loans and applicable Percentage of L/C Obligations on such day. Accrued and unpaid utilization fees, if any, shall be payable in arrears on the last Business Day of each March, June, September and December, on the date(s) on which the Commitments shall have terminated and there are no Loans or L/C Obligations outstanding, and on the Maturity Date. All utilization fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) Letter of Credit Fees. Commencing March 31, 2007, and thereafter on the last Business Day of each March, June, September and December, the Company shall pay to the Administrative Agent quarterly in arrears, for the period until the next Letter of Credit fee payment date, for the ratable account of the Lenders, a non-refundable fee payable in Dollars equal to the Applicable Margin multiplied by the outstanding face amount or increase of such Letter of Credit during such period calculated on the basis of a 360 day year and actual days elapsed and based on the then scheduled expiration date of the Letter of Credit. For any Letter of Credit issued with a face amount in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner, the fees shall be converted into Dollars using the applicable Exchange Rate in effect five (5) Business Days before any fee with respect thereto shall be due and payable hereunder. In addition, the Company shall pay to each Issuing Bank solely for such Issuing Bank’s account, in connection with each Letter of Credit issued by such Issuing Bank, customary issuance and administrative fees, fronting fees and expenses for such Letter of Credit as agreed from time to time between such Issuing Bank and the Company.

(d) Administrative Agent and Arrangement Fees. The Company shall pay to the Administrative Agent the fees from time to time agreed to by the Company and the Administrative Agent and the arrangement fees previously agreed to by the Company and the Co-Lead Arrangers.

(e) Payment of Fees. All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of facility fees, utilization fees, and Letter of Credit fees (other than issuance and administrative fees payable to the Issuing Banks), to the Lenders.

Section 3.2. Place and Application of Payments.

(a) All payments of principal of and interest on the Loans, Reimbursement Obligations and all fees and other amounts payable by any Credit Party under the Credit Documents shall be made free and clear of any set-off, counterclaim or defense by such Credit Party to the Administrative Agent (or, in the case of Swingline Loans, to the Swingline Lender, except as provided in Section 2.17), for the benefit of the Lenders and the Issuing Banks entitled to such payments, in immediately available funds on the due date thereof (i) in the case of payments in U.S. Dollars, no later than 2:00 P.M. in the applicable Administrative Agent’s Account or such other location as the Administrative Agent may designate in writing to the Company, and (ii) in the case of payments in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner, no later than 11:00 A.M. (at the office of the applicable Administrative Agent’s Account for payments in such currency) in the applicable Administrative Agent’s Account. Any payments received by the Administrative Agent from any Credit Party after the time specified in the preceding sentence shall be deemed to have been received on the next Business Day. If the applicable Borrower does not, or is unable for any reason to, effect payment of a Loan or Reimbursement Obligation to the Lenders in the applicable currency or if the applicable Borrower shall default in the payment when due of any payment in such currency, the Lenders may, at their option, require such payment to be made to the Lenders in the Dollar Equivalent of such currency determined in accordance with Section 10.19. With respect to any amount due and payable in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner, each Borrower agrees to hold the Lenders harmless from any losses, if any, that are incurred by the Lenders arising from any change in the value of Dollars in relation to such currency between the date such payment became due and the date of payment thereof (other than losses incurred by any Lender due to the gross negligence or willful misconduct of such Lender). The Administrative Agent will, on the same day each payment is received or deemed to have been received in accordance with this Section 3.2, cause to be distributed like funds in like currency to each Lender owed an Obligation for which such payment was received, pro rata based on the respective amounts of such type of Obligation then owing to each Lender.

(b) If any payment received by the Administrative Agent under any Credit Document is insufficient to pay in full all amounts then due and payable to the Administrative Agent and the Lenders under the Credit Documents, such payment shall be distributed by the Administrative Agent and applied by the Administrative Agent and the Lenders in the order set forth in Section 7.7. In calculating the amount of Obligations owing each Lender other than for principal and interest on Loans and Reimbursement Obligations and fees under Section 3.1, the Administrative Agent shall only be required to include such other Obligations that Lenders have certified to the Administrative Agent in writing are due to such Lenders.

Section 3.3. Withholding Taxes.

(a) Payments Free of Withholding. Except as otherwise required by law and subject to Section 3.3(b), each payment by or on behalf of the Borrowers to any Lender, any Issuing Bank, the Swingline Lender or the Administrative Agent under or in connection with this Agreement or any other Credit Document shall be made without withholding for or on account of any present or future taxes. If any such withholding is so required, the applicable Borrower shall make the withholding and pay the amount withheld to the appropriate governmental

authority before penalties attach thereto or interest accrues thereon. Moreover, in the case of any such present or future taxes imposed by or within the jurisdiction in which the applicable Borrower is incorporated, any jurisdiction from which the applicable Borrower makes any payment under this Agreement or any other Credit Document, or (in each case) any political subdivision or taxing authority thereof or therein, excluding, in the case of each Lender, each Issuing Bank, the Swingline Lender and the Administrative Agent, the following taxes:

(i) taxes imposed on, based upon, or measured by such Lender’s, such Issuing Bank’s, the Swingline Lender’s or the Administrative Agent’s net income, profits, gains, overall revenues or receipts, and branch profits, franchise and similar taxes imposed on it;

(ii) taxes imposed on such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent as a result of a present or former connection between the taxing jurisdiction and such Lender, such Issuing Bank, the Swingline Lender or Administrative Agent, or any owner or affiliate thereof, as the case may be, other than a connection resulting solely from the transactions contemplated by this Agreement;

(iii) taxes imposed as a result of the transfer by such Lender, such Issuing Bank, the Swingline Lender or Administrative Agent of its interest in this Agreement or any other Credit Document or a designation by such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent (other than pursuant to Section 8.3(c)) of a new Lending Office (other than taxes imposed as a result of any change in treaty, law or regulation after such transfer of such Lender’s, such Issuing Bank’s, the Swingline Lender’s or the Administrative Agent’s interest in this Agreement or any other Credit Document or designation of a new Lending Office);

(iv) taxes imposed by the United States of America (or any political subdivision thereof or tax authority therein) upon a Lender, Issuing Bank, Swingline Lender or Administrative Agent organized under the laws of a jurisdiction outside of the United States, except to the extent that such tax is imposed as a result of any change in applicable law, regulation or treaty (other than any addition of or change in any “anti-treaty shopping,” “limitation of benefits,” or similar provision applicable to a treaty) after the date hereof, in the case of each Lender, Issuing Bank, Swingline Lender or Administrative Agent originally a party hereto or, in the case of any Purchasing Lender (as defined in Section 10.10(b)) or other Issuing Bank or Administrative Agent, after the date on which it becomes a Lender, Issuing Bank, or Administrative Agent, as the case may be; or

(v) taxes which would not have been imposed but for (a) the failure of such Lender, such Issuing Bank, the Swingline Bank or the Administrative Agent, as the case may be, to provide on a timely basis (I) the applicable forms prescribed by the Internal Revenue Service, as required pursuant to Section 3.3(b) (unless excused pursuant to Section 3.3(c)), or (II) any other form, certification, documentation or proof which is reasonably requested by the Company and which can be lawfully delivered by such Lender, or (b) a determination by a taxing authority or a court of competent jurisdiction that a form, certification, documentation or other proof provided by such Lender, such

Issuing Bank, the Swingline Lender or the Administrative Agent to establish an exemption from such tax, assessment or other governmental charge is false or not properly completed;

(all such present or future taxes, excluding only the taxes described in the preceding clauses (i) through (v), being hereinafter referred to as “Indemnified Taxes”), the applicable Borrower shall forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Lender, each Issuing Bank, the Swingline Lender and the Administrative Agent is free and clear of such Indemnified Taxes (including Indemnified Taxes on such additional amount) and is equal to the amount that such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent (as the case may be) would have received had withholding of any Indemnified Taxes not been made. If any Borrower pays any Indemnified Taxes, or any penalties or interest in connection therewith, it shall deliver official tax receipts evidencing the payment or certified copies thereof, or other evidence of payment if such tax receipts have not yet been received by such Borrower (with such tax receipts to be delivered within fifteen (15) days after being actually received), to the Lender, Issuing Bank or the Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) within fifteen (15) days of such payment. If the Administrative Agent, any Issuing Bank, the Swingline Lender or any Lender pays any Indemnified Taxes which any Borrower has failed to withhold or pay to the appropriate governmental authority, or any penalties or interest in connection therewith, such Borrower shall reimburse the Administrative Agent, that Issuing Bank, the Swingline Lender or that Lender for the payment in the currency in which such payment was made within thirty (30) days after the receipt of written demand therefor. Such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent shall make written demand on the Company for reimbursement hereunder no later than ninety (90) days after the earlier of (i) the date on which such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent makes payment of the Indemnified Taxes, penalties and interest, and (ii) the date on which the relevant taxing authority or other governmental authority makes written demand upon such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent for payment of the Indemnified Taxes, penalties and interest. Any such demand shall describe in reasonable detail such Indemnified Taxes, penalties or interest, including the amount thereof if then known to such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent, as the case may be. In the event that such Lender, Issuing Bank or the Administrative Agent fails to give the Company timely notice as provided herein, no Borrower shall have any obligation to pay such claim for reimbursement. In the event that any taxing authority notifies a Borrower that it has improperly failed to withhold any taxes (other than Indemnified Taxes) from a payment to any Lender, any Issuing Bank, the Swingline Lender or the Administrative Agent under this Agreement or any other Credit Document, such Borrower shall timely and fully pay such taxes to such taxing authority and such Lender, Issuing Bank, Swingline Lender or Administrative Agent, as the case may be, shall pay the amount of such taxes to such Borrower within thirty (30) days after the receipt of written demand therefor. If a Borrower is or will be required to pay an additional amount to a Lender, an Issuing Bank, the Swingline Lender or the Administrative Agent pursuant to this Section 3.3(a), then such payee shall use reasonable efforts to take requested measures (including, without limitation, changing the jurisdiction of its Lending Office) so as to reduce or eliminate any such amounts which may thereafter accrue, if such change would not otherwise be materially disadvantageous to such payee.

(b) U.S. Withholding Tax Exemptions. Upon the written request of the Company or the Administrative Agent, each Lender or Issuing Bank that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to the Company and the Administrative Agent, promptly after such request, two duly completed and signed copies of either Form W-8BEN or any successor form (entitling such Lender or Issuing Bank to a complete exemption from withholding under the Code on all amounts to be received by such Lender or Issuing Bank, including fees, pursuant to the Credit Documents) or Form W-8ECI or any successor form (relating to all amounts to be received by such Lender or Issuing Bank, including fees, pursuant to the Credit Documents) of the United States Internal Revenue Service, and any other form of the United States Internal Revenue Service reasonably necessary to accomplish exemption from withholding obligations or to facilitate the Administrative Agent’s performance under this Agreement. Thereafter and from time to time, each such Lender or Issuing Bank shall submit to the Company and the Administrative Agent such additional duly completed and signed copies of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be required under then-current United States law or regulations to avoid United States withholding taxes on payments in respect of all amounts to be received by such Lender or Issuing Bank, including fees, pursuant to the Credit Documents. Upon the request of the Company, each Lender or Issuing Bank that is a United States person shall submit to the Company a certificate to the effect that it is such a United States person and is exempt from information reporting under Section 6049 of the Code and backup withholding under Section 3406 of the Code.

(c) Inability of Lender to Submit Forms. If any Lender or Issuing Bank determines in good faith, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that (i) it is unable to submit to the Company or Administrative Agent any form or certificate that such Lender or Issuing Bank is obligated to submit pursuant to subsection (b) of this Section 3.3, (ii) it is required to withdraw or cancel any such form or certificate previously submitted, or (iii) any such form or certificate otherwise becomes ineffective or inaccurate, such Lender or Issuing Bank shall promptly notify the Company and Administrative Agent of such fact, and such Lender or Issuing Bank shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable.

(d) Refund of Taxes. If any Lender, Issuing Bank, Swingline Lender or the Administrative Agent receives a refund or credit of any Indemnified Tax or any tax referred to in Section 10.3 with respect to which any Borrower has paid any amount pursuant to this Section 3.3 or Section 10.3, such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent shall pay the amount of such refund or credit (including any interest received with respect thereto) to such Borrower within fifteen (15) days after receipt thereof. A Lender, Issuing Bank, or the Administrative Agent shall provide, at the sole cost and expense of the Company, such assistance as the Company may reasonably request in order to obtain such a refund or credit; provided, however, that none of the Administrative Agent, any Lender, any Issuing Bank or Swingline Lender shall in any event be required to disclose any information to the Company with respect to the overall tax position (or any other information relating to taxes that such Person reasonably determines to be confidential) of the Administrative Agent, Issuing Bank, the Swingline Lender or such Lender.

Section 5.1. Corporate Organization. The Company and each of its Significant Subsidiaries: (i) is duly organized and existing in good standing under the laws of the jurisdiction of its organization; (ii) has all necessary organizational power and authority to own the property and assets it uses in its business and otherwise to carry on its present business; and (iii) is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the property owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified or to be in good standing, as the case may be, would not have a Material Adverse Effect.

Section 5.2. Power and Authority; Validity. Each of the Credit Parties has the organizational power and authority to execute, deliver and carry out the terms and provisions of the Credit Documents to which it is a party and has taken all necessary company action to authorize the execution, delivery and performance of such Credit Documents. Each of the Credit Parties has duly executed and delivered each Credit Document to which it is a party and each such Credit Document constitutes the legal, valid and binding obligation of such Credit Party which is a party thereto enforceable against it in accordance with its terms, subject as to enforcement only to bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and equitable principles.

Section 5.3. No Violation. Neither the execution, delivery or performance by any Credit Party of the Credit Documents to which it is a party nor compliance by it with the terms and provisions thereof, nor the consummation by it of the transactions contemplated herein or therein, will (i) contravene in any material respect any applicable provision of any law, statute, rule or regulation, or any applicable order, writ, injunction or decree of any court or governmental instrumentality, (ii) conflict with or result in any breach of any term, covenant, condition or other provision of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien other than any Permitted Lien upon any of the property or assets of such Credit Party or any of its Subsidiaries under, the terms of any material contractual obligation to which such Credit Party or any of its Subsidiaries is a party or by which they or any of their properties or assets are bound or to which they may be subject, or (iii) violate or conflict with any provision of the memorandum of association and articles of association, charter, articles or certificate of incorporation, partnership or limited liability company agreement, by-laws, or other applicable governance documents of such Credit Party or any of its Subsidiaries.

After application of the proceeds of the Loans, the issuance of the Letters of Credit, and any acquisitions permitted hereunder, less than 25% of the assets of each of the Company and its Subsidiaries consists of “margin stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System).

Section 5.9. Financial Statements. The financial statements heretofore delivered to the Lenders for the Company’s fiscal year ending December 31, 2006 have been prepared in accordance with GAAP applied on a basis consistent, except as otherwise noted therein, with the Company’s financial statements for the previous fiscal year. Such annual and quarterly financial statements fairly present in all material respects on a consolidated basis the financial position of the Company as of the dates thereof, and the results of operations for the periods indicated, subject in the case of interim financial statements, to normal year-end audit adjustments and omission of certain footnotes (as permitted by the SEC).

The Company and its Subsidiaries own or hold valid licenses to use all the patents, trademarks, permits, service marks, and trade names that are necessary to the operation of the business of the Company and its Subsidiaries as presently conducted, except where the failure to own, or hold valid licenses to use, such patents, trademarks, permits, service marks, and trade names could not reasonably be expected to have a Material Adverse Effect.

Section 5.15. Ownership of Property. The Company and its Subsidiaries have good title to or a valid leasehold interest in all of their real property and good title to, or a valid leasehold interest in, all of their other property, subject to no Liens except Permitted Liens, except where the failure to have such title or leasehold interest in such property could not reasonably be expected to have a Material Adverse Effect.

Section 5.16. Existing Indebtedness. Schedule 5.16 contains a complete and accurate list of all Indebtedness outstanding as of the Effective Date, with respect to the Company and its Subsidiaries, in each case in a principal amount of $20,000,000 (or, if denominated in a currency other than U.S. Dollars, the Dollar Equivalent of $20,000,000) or more (other than the Obligations hereunder and Indebtedness permitted by Section 6.11), in each case showing the aggregate principal amount thereof, the name of the respective borrower and any other entity which directly or indirectly guaranteed such Indebtedness, and the scheduled payments of such Indebtedness.

Each of the Company and its Significant Subsidiaries will preserve and maintain its organizational existence, except (i) for the dissolution of any Significant Subsidiaries (other than NDC, unless and until released pursuant to the terms of the NDC Guaranty) whose assets are transferred to the Company or any of its Subsidiaries, (ii) where the failure to preserve, renew or keep in full force and effect the existence of any Subsidiary (other than NDC, unless and until released pursuant to the terms of the NDC Guaranty) could not reasonably be expected to have a Material Adverse Effect, or (iii) as otherwise expressly permitted in this Agreement.

date stated in such notice (which may be the date thereof) and such termination shall automatically also terminate the Swingline Commitment on such date; (b) if so directed by the Required Lenders, declare the principal of and the accrued interest on all outstanding Loans to be forthwith due and payable and thereupon all outstanding Loans, including both principal and interest thereon, shall be and become immediately due and payable together with all other accrued amounts payable under the Credit Documents without further demand, presentment, protest or notice of any kind, including, but not limited to, notice of intent to accelerate and notice of acceleration, each of which is expressly waived by the Borrowers; and (c) if so directed by the Required Lenders, demand that the Company immediately pay to the Administrative Agent (to be held by the Administrative Agent pursuant to Section 7.4) the full amount then available for drawing under each outstanding Letter of Credit, and the Company agrees to immediately make such payment, and each Borrower acknowledges and agrees that the Lenders, the Issuing Banks, the Swingline Bank and the Administrative Agent would not have an adequate remedy at law for failure by the Borrowers to honor any such demand and that the Administrative Agent, for the benefit of the Lenders, the Swingline Lender and the Issuing Banks, shall have the right to require the Borrowers to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any Letter of Credit. The Administrative Agent, after giving notice to the Company pursuant to this Section 7.2, shall also promptly send a copy of such notice to the other Lenders, the Swingline Lender and the Issuing Bank, but the failure to do so shall not impair or annul the effect of such notice.

Section 7.3. Bankruptcy Defaults. When any Event of Default described in subsections (f) or (g) of Section 7.1 has occurred and is continuing with respect to any Credit Party, then all outstanding Loans shall immediately become due and payable together with all other accrued amounts payable under the Credit Documents without presentment, demand, protest or notice of any kind, each of which is expressly waived by the Borrowers; and all obligations of the Lenders, the Swingline Lender and the Issuing Banks to extend further credit pursuant to any of the terms hereof shall immediately terminate and the Company shall immediately pay to the Administrative Agent (to be held by the Administrative Agent pursuant to Section 7.4) the full amount then available for drawing under all outstanding Letters of Credit, each Borrower acknowledging that the Lenders, the Issuing Banks, the Swingline Lender and the Administrative Agent would not have an adequate remedy at law for failure by the Borrowers to honor any such demand and that the Lenders, the Issuing Banks, the Swingline Lender and the Administrative Agent shall have the right to require the Borrowers to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any of the Letters of Credit.

Section 7.4. Collateral for Undrawn Letters of Credit.

(a) If the prepayment of the amount available for drawing under any or all outstanding Letters of Credit is required under Section 7.2 or 7.3, the Company shall forthwith pay the amount required to be so prepaid, to be held by the Administrative Agent as provided in subsection (b) below.

(b) All amounts prepaid pursuant to subsection (a) above shall be held by the Administrative Agent in a separate collateral account (such account, and the credit balances, properties and any investments from time to time held therein, and any substitutions for such

account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the “Collateral Account”) as security for, and for application to, the reimbursement of any drawing under any Letter of Credit then or thereafter paid by any Issuing Bank, and to the payment of any Revolving Loans, any Swingline Loans and all other unpaid Obligations then due and owing (collectively, the “Collateralized Obligations”). The Collateral Account shall be held in the name of and subject to the exclusive dominion and control of the Administrative Agent, for the benefit of the Issuing Banks, the Swingline Lender, the Administrative Agent, and the Lenders, as pledgee hereunder. If and when required by the Company, the Administrative Agent shall invest and reinvest funds held in the Collateral Account from time to time in Cash Equivalents specified from time to time by the Company, provided that the Administrative Agent is irrevocably authorized to sell on market terms any investments held in the Collateral Account when and as required to make payments out of the Collateral Account for application to Collateralized Obligations due and owing. When and if (A) (i) the Company shall have made payment of all Collateralized Obligations then due and payable, and (ii) all relevant preference or other disgorgement periods relating to the receipt of such payments have passed, or (B) no Default or Event of Default shall be continuing, the Administrative Agent shall repay to the Company any remaining amounts and assets held in the Collateral Account, provided that if the Collateral Account is being released pursuant to clause (A) and any Letter of Credit then remains outstanding, the Company, prior to or contemporaneously with such release, shall provide the Administrative Agent a back-to-back letter of credit from a bank or financial institution whose short-term unsecured debt rating is rated A or above from either S&P or ▇▇▇▇▇’▇ or such other bank or financial institution satisfactory to the Required Lenders in either case in an amount equal to the undrawn face amount of each such Letter of Credit and which provides that the Administrative Agent may make a drawing thereunder in the event that an Issuing Bank pays a drawing under such Letter of Credit. In addition, if the aggregate amount on deposit with the Collateral Agent exceeds the Collateralized Obligations then existing, then the Administrative Agent shall release and deliver such excess amount upon the written request of the Company.

Section 7.5. Notice of Default. The Administrative Agent shall give notice to the Company under Section 7.2 promptly upon being requested to do so by the Required Lenders and shall thereupon notify all the Lenders thereof.

Section 7.6. Expenses. The Company agrees to pay to the Administrative Agent, each Issuing Bank, the Swingline Lender and each Lender all reasonable out-of-pocket expenses incurred or paid by the Administrative Agent, the Issuing Bank, or such Lender, including reasonable attorneys’ fees and court costs, in connection with any Default or Event of Default hereunder or in connection with the enforcement of any of the Credit Documents.

Section 7.7. Distribution and Application of Proceeds. After the occurrence of and during the continuance of an Event of Default, any payment to the Administrative Agent, any Issuing Bank, the Swingline Lender or any Lender hereunder or from the proceeds of the Collateral Account or otherwise shall be paid to the Administrative Agent to be distributed and applied as follows (unless otherwise agreed by the Company, the Administrative Agent, all Issuing Banks, the Swingline Lender and all Lenders):

(a) First, to the payment of any and all reasonable out-of-pocket costs and expenses of the Administrative Agent, including without limitation, reasonable attorneys’ fees and out-of-pocket costs and expenses, as provided by this Agreement or by any other Credit Document, incurred in connection with the collection of such payment or in respect of the enforcement of any rights of the Administrative Agent, the Issuing Banks, the Swingline Lender or the Lenders under this Agreement or any other Credit Document;

(b) Second, to the payment of any and all reasonable out-of-pocket costs and expenses of the Issuing Banks, the Swingline Lender and the Lenders, including, without limitation, reasonable attorneys’ fees and out-of-pocket costs and expenses, as provided by this Agreement or by any other Credit Document, incurred in connection with the collection of such payment or in respect of the enforcement of any rights of the Lenders, the Swingline Lender or the Issuing Banks under this Agreement or any other Credit Document, pro rata in the proportion in which the amount of such costs and expenses unpaid to each Lender, the Swingline Lender or each Issuing Bank bears to the aggregate amount of the costs and expenses unpaid to all Lenders, the Swingline Lender and all Issuing Banks collectively, until all such fees, costs and expenses have been paid in full;

(c) Third, to the payment of any due and unpaid fees to the Administrative Agent, any Lender, the Swingline Lender or any Issuing Bank as provided by this Agreement or any other Credit Document, pro rata in the proportion in which the amount of such fees due and unpaid to the Administrative Agent, each Lender, the Swingline Lender, and each Issuing Bank bears to the aggregate amount of the fees due and unpaid to the Administrative Agent, all Lenders, the Swingline Lender and all Issuing Banks collectively, until all such fees have been paid in full;

(d) Fourth, to the payment of accrued and unpaid interest on the Loans or the Reimbursement Obligations to the date of such application, pro rata in the proportion in which the amount of such interest, accrued and unpaid to each Lender, the Swingline Lender or each Issuing Bank bears to the aggregate amount of such interest accrued and unpaid to all Lenders, the Swingline Lender and all Issuing Banks collectively, until all such accrued and unpaid interest has been paid in full;

(e) Fifth, to the payment of the outstanding due and payable principal amount of each of the Loans and the amount of the outstanding Reimbursement Obligations (reserving cash collateral for all undrawn face amounts of any outstanding Letters of Credit (if Section 7.4(a) has not been complied with)), pro rata in the proportion in which the outstanding principal amount of such Loans and the amount of such outstanding Reimbursement Obligations owing to each Lender, the Swingline Lender and each Issuing Bank, together (if Section 7.4(a) has not been complied with) with the undrawn face amounts of such outstanding Letters of Credit, bears to the aggregate amount of all outstanding Loans, outstanding Reimbursement Obligations and (if Section 7.4(a) has not been complied with) the undrawn face amounts of all outstanding Letters of Credit. In the event that any such Letters of Credit, or any portions thereof, expire without being drawn, any cash collateral therefor shall be distributed by the Administrative Agent until the principal amount of all Loans and Reimbursement Obligations shall have been paid in full;

(f) Sixth, to the payment of any other outstanding Obligations then due and payable, pro rata in the proportion in which the outstanding Obligations owing to each Lender, each Issuing Bank, the Swingline Lender and Administrative Agent bears to the aggregate amount of all such Obligations until all such Obligations have been paid in full; and

(g) Seventh, to a Borrower or as the Company may direct.

ARTICLE 8

CHANGE IN CIRCUMSTANCES.

Section 8.1. Change of Law.

(a) Notwithstanding any other provisions of this Agreement or any Note, if at any time any change, after the date hereof (or, if later, after the date the Administrative Agent or any Issuing Bank or Lender becomes the Administrative Agent or an Issuing Bank or Lender), in applicable law or regulation or in the interpretation thereof makes it unlawful for any Lender to make or maintain Eurocurrency Loans or to fund any Loans in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner, or any Issuing Bank to issue any Letter of Credit or to provide payment thereunder in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner, such Lender or Issuing Bank, as the case may be, shall promptly give written notice thereof and of the basis therefor in reasonable detail to the Company, and such Lender’s or Issuing Bank’s obligations to fund affected Eurocurrency Loans or make, continue or convert such Loans under this Agreement, or to issue any such Letters of Credit, as the case may be, shall thereupon be suspended until it is no longer unlawful for such Lender to make or maintain such Loans or such Issuing Bank to issue such Letters of Credit.

(b) Upon the giving of the notice to Company referred to in subsection (a) above in respect of any such Loan, and provided the applicable Borrower shall not have prepaid such Loan pursuant to Section 2.9, (i) any such outstanding Loan of such Lender shall be automatically converted to a Base Rate Loan in Dollars on the last day of the Interest Period then applicable thereto or on such earlier date as required by law, and (ii) such Lender shall make or continue its portion of any requested Borrowing of such Loan as a Base Rate Loan in U.S. Dollars, which Base Rate Loan shall, for all other purposes, be considered part of such Borrowing.

(c) Any Lender or Issuing Bank that has given any notice pursuant to Section 8.1(a) shall, upon determining that it would no longer be unlawful for it to make such Loans or issue such Letters of Credit, give prompt written notice thereof to the Company and the Administrative Agent, and upon giving such notice, its obligation to make, allow conversions into and maintain such Loans or issue such Letters of Credit shall be reinstated.

Section 8.2. Unavailability of Deposits or Inability to Ascertain LIBOR Rate. If on or before the first day of any Interest Period for any Borrowing of Eurocurrency Loans the Administrative Agent determines in good faith (after consultation with the other Lenders) that, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the LIBOR Rate (including without limitation, the unavailability of matching

deposits in the applicable currency) or such rate will not accurately reflect the cost to the Required Lenders of funding Eurocurrency Loans in the applicable currency for such Interest Period, the Administrative Agent shall give written notice (in reasonable detail) of such determination and of the basis therefor to the Company and the Lenders, whereupon until the Administrative Agent notifies the Company and Lenders that the circumstances giving rise to such suspension no longer exist (which the Administrative Agent shall do promptly after they do not exist), (i) the obligations of the Lenders to fund Loans in Euro, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner, or make, continue or convert Loans as or into such Eurocurrency Loans, or to convert Base Rate Loans into such Eurocurrency Loans, shall be suspended and (ii) each Eurocurrency Loan will automatically on the last day of the then existing Interest Period therefor, convert into a Base Rate Loan in U.S. Dollars.

Section 8.3. Increased Cost and Reduced Return.

(a) If, on or after the date hereof, the adoption of or any change in any applicable law, rule or regulation, 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 any Lender or Issuing Bank (or its applicable Lending Office), with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency exercising control over banks or financial institutions generally issued after the date hereof (or, if later, after the date the Administrative Agent, Issuing Bank, or Lender becomes the Administrative Agent, Issuing Bank, or Lender):

(i) subjects any Lender or Issuing Bank (or its applicable Lending Office) to any tax, duty or other charge related to any Eurocurrency Loan, Reimbursement Obligation, or its obligation to advance or maintain Eurocurrency Loans or issue any Letter of Credit, or shall change the basis of taxation of payments to any Lender or Issuing Bank (or its applicable Lending Office) of the principal of or interest on its Eurocurrency Loans, Letters of Credit or Reimbursement Obligation or any participations in any thereof, or any other amounts due under this Agreement related to its Eurocurrency Loans, Letters of Credit, Reimbursement Obligations or participations therein, or its obligation to make Eurocurrency Loans, issue Letters of Credit, or acquire participations therein (except for changes with respect to taxes that are not Indemnified Taxes pursuant to Section 3.3); or

(ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding for any Eurocurrency Loan any such requirement included in an applicable Statutory Reserve Rate) against assets of, deposits with or for the account of, or credit extended by, any Lender or Issuing Bank (or its applicable Lending Office) or imposes on any Lender or Issuing Bank (or its Lending Office) or on the interbank market any other condition affecting its Eurocurrency Loans, Letters of Credit, any Reimbursement Obligations owed to it, or its participation in any thereof, or its obligation to advance or maintain Eurocurrency Loans, issue Letters of Credit or participate in any thereof;

and the result of any of the foregoing is to increase the cost to such Lender or Issuing Bank (or its applicable Lending Office) of advancing or maintaining any Eurocurrency Loan, issuing or maintaining a Letter of Credit or participating therein, or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank (or its applicable Lending Office) in connection therewith under this Agreement or its Note, by an amount deemed by such Lender or Issuing Bank to be material, then, subject to Section 8.3(c), from time to time, within thirty (30) days after receipt of a certificate from such Lender or Issuing Bank (with a copy to the Administrative Agent) pursuant to subsection (c) below setting forth in reasonable detail such determination and the basis thereof, the Company shall be obligated to pay (or cause the applicable Designated Borrower to pay) to such Lender or Issuing Bank such additional amount or amounts as will compensate such Lender or Issuing Bank for such increased cost or reduction.

(b) If, after the date hereof, the Administrative Agent, any Lender, the Swingline Lender or Issuing Bank shall have reasonably determined that the adoption after the date hereof of any applicable law, rule or regulation regarding capital adequacy, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; ▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇ ▇) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital adequacy rules heretofore adopted and issued by any governmental authority), or any change after the date hereof 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 the Administrative Agent, any Lender, the Swingline Lender or Issuing Bank (or its applicable Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s, Issuing Bank’s or Swingline Lender’s capital, or on the capital of any corporation controlling such Lender, Issuing Bank or Swingline Lender, as a consequence of its obligations hereunder to a level below that which such Lender, Issuing Bank or Swingline Lender could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s, Issuing Bank’s, Swingline Lender’s or its controlling corporation’s policies with respect to capital adequacy in effect immediately before such adoption, change or compliance) by an amount reasonably deemed by such Lender, Issuing Bank or Swingline Lender to be material, then, subject to Section 8.3(c), from time to time, within thirty (30) days after its receipt of a certificate from such Lender, Issuing Bank or Swingline Lender (with a copy to the Administrative Agent) pursuant to subsection (c) below setting forth in reasonable detail such determination and the basis thereof, the Company shall pay (or cause the applicable Designated Borrower to pay) to such Lender, Issuing Bank or Swingline Lender such additional amount or amounts as will compensate such Lender, Issuing Bank or Swingline Lender for such reduction or the applicable Borrower may prepay all Eurocurrency Loans of such Lender or obtain the cancellation of all such Letters of Credit.

(c) Each of the Administrative Agent, the Lenders, the Swingline Lender and the Issuing Banks that determines to seek compensation or additional interest under this Section 8.3 or Section 2.15 shall give written notice to the Company and, in the case of a Lender, the Swingline Lender or a Issuing Bank other than the Administrative Agent, the Administrative Agent of the circumstances that entitle the Administrative Agent, such Lender, the Swingline Lender or such Issuing Bank to such compensation no later than ninety (90) days after the

Administrative Agent, such Lender, the Swingline Lender or such Issuing Bank receives actual notice or obtains actual knowledge of the law, rule, order or interpretation or occurrence of another event giving rise to a claim hereunder. In any event no Borrower shall have any obligation to pay any amount with respect to claims accruing prior to the ninetieth day preceding such written demand. Each of the Administrative Agent, the Lenders, the Swingline Lender and the Issuing Banks shall use reasonable efforts to avoid the need for, or reduce the amount of, such compensation, additional interest, and any payment under Section 3.3, including, without limitation, the designation of a different Lending Office, if such action or designation will not, in the sole judgment of the Administrative Agent, such Lender, the Swingline Lender or such Issuing Bank made in good faith, be otherwise disadvantageous to it; provided that the foregoing shall not in any way affect the rights of any Lender, the Swingline Lender or any Issuing Bank or the obligations of the Borrowers under this Section 8.3 or Section 2.15. A certificate of the Administrative Agent, any Lender, the Swingline Lender or any Issuing Bank, as applicable, claiming compensation or additional interest under this Section 8.3 or Section 2.15, and setting forth the additional amount or amounts to be paid to it hereunder and accompanied by a statement prepared by the Administrative Agent, such Lender, Swingline Lender or such Issuing Bank, as applicable, describing in reasonable detail the calculations thereof shall be prima facie evidence of the correctness thereof. In determining such amount, such Lender, the Swingline Lender or such Issuing Bank may use any reasonable averaging and attribution methods.

Section 8.4. Lending Offices. The Administrative Agent, the Swingline Lender, each Lender and each Issuing Bank may, at its option, elect to make or maintain its Loans and issue its Letters of Credit hereunder at the Lending Office for each Type and/or currency of Loan or Letter of Credit available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to the Company and the Administrative Agent, provided that, except in the case of any such transfer to another of its branches, offices or affiliates made at the request of the Company, no Borrower shall be responsible for the costs arising under Section 3.3 or 8.3 resulting from any such transfer to the extent not otherwise applicable to such Lender, the Swingline Lender or such Issuing Bank prior to such transfer.

Section 8.5. Discretion of Lender as to Manner of Funding. Subject to the other provisions of this Agreement, each Lender, the Swingline Lender and each Issuing Bank shall be entitled to fund and maintain its funding of all or any part of its Loans and Letters of Credit in any manner it sees fit.

Section 8.6. Substitution of Lender or Issuing Bank. If (a) any Lender or Issuing Bank has demanded compensation or additional interest or given notice of its intention to demand compensation or additional interest under Section 8.3 or Section 2.15, (b) a Borrower is required to pay any additional amount to any Lender or Issuing Bank under Section 2.11, (c) any Lender or Issuing Bank is unable to submit any form or certificate required under Section 3.3(b) or withdraws or cancels any previously submitted form with no substitution therefor, (d) any Lender or Issuing Bank gives notice of any change in law or regulations, or in the interpretation thereof, pursuant to Section 8.1, (e) any Lender or Issuing Bank has been declared insolvent or a receiver or conservator has been appointed for a material portion of its assets, business or properties, (f) any Lender or Issuing Bank shall seek to avoid its obligation to make or maintain Loans or issue Letters of Credit hereunder for any reason, including, without limitation, reliance upon 12 U.S.C. § 1821(e) or (n) (1) (B), (g) any taxes referred to in Section 3.3 have been levied

or imposed (or the Company determines in good faith that there is a substantial likelihood that such taxes will be levied or imposed) so as to require withholding or deductions by a Borrower or payment by a Borrower of additional amounts to any Lender or Issuing Bank, or other reimbursement or indemnification of any Lender or Issuing Bank, as a result thereof, (h) any Lender shall decline to consent to a modification or waiver of the terms of this Agreement or any other Credit Documents requested by the Company to which the Required Lenders have consented, or (i) an Issuing Bank gives notice pursuant to Section 2.12(a)(ii) that the issuance of the Letter of Credit would violate any legal or regulatory restriction then applicable to such Issuing Bank, then and in such event, upon request from the Company delivered to such Lender or Issuing Bank, and the Administrative Agent, such Lender shall assign, in accordance with the provisions of Section 10.10 and an appropriately completed Assignment Agreement, all of its rights and obligations under the Credit Documents to another Lender or a commercial banking institution selected by the Company and (in the case of a commercial banking institution) reasonably satisfactory to the Administrative Agent, in consideration for the payments set forth in such Assignment Agreement and payment by the Company (or the Company shall cause the applicable Designated Borrower to pay) to such Lender of all other amounts which such Lender may be owed pursuant to this Agreement, including, without limitation, Sections 2.11, 2.15, 3.3, 8.3 and 10.13.

ARTICLE 9

THE AGENTS AND ISSUING BANK.

Section 9.1. Appointment and Authorization of Administrative Agent and Other Agents. Each of the Lenders and the Swingline Lender hereby appoints Citibank, N.A. as the Administrative Agent, SunTrust Bank, as the Syndication Agent, and The Bank of Tokyo-Mitsubishi UFJ, Ltd., Houston Agency, Fortis Capital Corp., and ▇▇▇▇▇ Fargo Bank, N.A., as the Co-Documentation Agents under the Credit Documents and hereby authorizes the Administrative Agent and such Other Agents to take such action as the Administrative Agent and such Other Agents on each of its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent and the Other Agents, respectively, by the terms thereof, together with such powers as are reasonably incidental thereto.

Section 9.2. Rights and Powers. The Administrative Agent and the Other Agents shall have the same rights and powers under the Credit Documents as any other Lender and may exercise or refrain from exercising such rights and power as though it were not an Administrative Agent, or an Other Agent, and the Administrative Agent and the Other Agents and their respective Controlling Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Company or any of its Subsidiaries or Controlling Affiliates as if it were not an Administrative Agent or an Other Agent under the Credit Documents. The term Lender as used in all Credit Documents, unless the context otherwise clearly requires, includes the Administrative Agent and the Other Agents in their respective individual capacities as a Lender. In the event that Citibank, N.A. or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by any Credit Party, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of such Credit Party hereunder or under any other Credit Document by or on behalf of Citibank,

N.A. in its capacity as the Administrative Agent or the Collateral Agent for the benefit of any Lender, the Swingline Lender or any Issuing Bank under any Credit Document (other than Citibank, N.A. or an Affiliate of Citibank, N.A.) and which is applied in accordance with the Credit Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

Section 9.3. Action by Administrative Agent and the Other Agents. The obligations of the Administrative Agent and the Other Agents under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action concerning any Default or Event of Default, except as expressly provided in Sections 7.2 and 7.4. Unless and until the Required Lenders (or, if required by Section 10.11, all of the Lenders) give such direction (including, without limitation, the giving of a notice of default as described in Section 7.1(c)), the Administrative Agent may, except as otherwise expressly provided herein or therein, take or refrain from taking such actions as it deems appropriate and in the best interest of all the Lenders and the Swingline Lender. In no event, however, shall the Administrative Agent or the Other Agents be required to take any action in violation of applicable law or of any provision of any Credit Document, and each of the Administrative Agent and the Other Agents shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it first receives any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses and any other protection it requires against any and all costs, expenses, and liabilities it may incur in taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Default or Event of Default, other than non-payment of any scheduled principal or interest payment due hereunder, exists unless notified in writing to the contrary by a Lender or the Company. In all cases in which the Credit Documents do not require the Administrative Agent or the Other Agents to take specific action, the Administrative Agent and each of the Other Agents shall be fully justified in using its discretion in failing to take or in taking any action thereunder. Any instructions of the Required Lenders, or of any other group of Lenders called for under specific provisions of the Credit Documents, shall be binding on all the Lenders and holders of Revolving Notes.

Section 9.4. Consultation with Experts. Each of the Administrative Agent and the Other Agents may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 9.5. Indemnification Provisions; Credit Decision. Neither the Administrative Agent, the Other Agents nor any of their directors, officers, agents, or employees shall be liable to any Lender for any action taken or not taken by them in connection with the Credit Documents (i) with the consent or at the request of the Required Lenders (or, if required by Section 10.11, all of the Lenders), or (ii) in the absence of their own gross negligence or willful misconduct. Neither the Administrative Agent, the Other Agents nor any of their directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Borrowing; (ii) the performance or observance of any of the covenants or agreements of the Company or any Subsidiary contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Article 4, except receipt of

items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness, genuineness, enforceability, value, worth or collectability hereof or of any other Credit Document or of any other documents or writings furnished in connection with any Credit Document; and the Administrative Agent and the Other Agents make no representation of any kind or character with respect to any such matters mentioned in this sentence. The Administrative Agent and the Other Agents may execute any of their duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent and the Other Agents shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Administrative Agent and the Other Agents shall have no responsibility for confirming the accuracy of any Compliance Certificate or other document or instrument received by any of them under the Credit Documents. The Administrative Agent and the Other Agents may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with such Administrative Agent signed by such owner in form satisfactory to such Administrative Agent. Each of the Lenders and the Swingline Lender acknowledges that it has independently, and without reliance on the Administrative Agent, the Other Agents, the Swingline Lender or any other Lender, obtained such information and made such investigations and inquiries regarding the Company and its Subsidiaries as it deems appropriate, and based upon such information, investigations and inquiries, made its own credit analysis and decision to extend credit to the Borrowers in the manner set forth in the Credit Documents. It shall be the responsibility of each Lender and the Swingline Lender to keep itself informed about the creditworthiness and business, properties, assets, liabilities, condition (financial or otherwise) and prospects of the Company and its Subsidiaries, and the Administrative Agent and the Other Agents shall have no liability whatsoever to any Lender or the Swingline Lender for such matters. The Administrative Agent and the Other Agents shall have no duty to disclose to the Lenders or the Swingline Lender information that is not required by any Credit Document to be furnished by the Company or any Subsidiaries to such Agent at such time, but is voluntarily furnished to such Agent (either in their respective capacity as Administrative Agent or the Other Agents or in their individual capacity).

Section 9.6. Indemnity. The Lenders shall ratably, in accordance with their Percentages, indemnify and hold the Administrative Agent, the Other Agents, and their directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed for the same by the Company and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Lenders under this Section 9.6 shall survive termination of this Agreement.

Section 9.7. Resignation.

(a) Resignation of Agents. The Administrative Agent and the Other Agents may resign at any time and shall resign upon any removal thereof as a Lender pursuant to the

terms of this Agreement upon at least thirty (30) days’ prior written notice to the Lenders and the Company. Any resignation of the Administrative Agent shall not be effective until a replacement therefor is appointed pursuant to the terms hereof. Upon any such resignation of the Administrative Agent or any Other Agent, the Required Lenders and, so long as no Event of Default shall then exist, with the consent of the Company (which consent shall not be unreasonably withheld or delayed) shall have the right to appoint a successor Administrative Agent or Other Agent, as the case may be. If no successor Administrative Agent or Other Agent, as the case may be, shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent’s or Other Agent’s giving of notice of resignation, then the retiring Administrative Agent or Other Agent, as the case may be, may, on behalf of the Lenders and, so long as no Event of Default shall then exist, with the consent of the Company (which consent shall not be unreasonably withheld or delayed) appoint a successor Administrative Agent or Other Agent, as the case may be, which shall be any Lender hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $1,000,000,000. Upon the acceptance of its appointment as the Administrative Agent or the Other Agent hereunder, such successor Administrative Agent or Other Agent, as the case may be, shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent or Other Agent, as the case may be, under the Credit Documents, and the retiring Administrative Agent or Other Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent’s or Other Agent’s resignation hereunder as Administrative Agent or Other Agent, as the case may be, the provisions of this Article 9 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Other Agent, as the case may be.

(b) Resignation of Issuing Banks. If at any time an Issuing Bank assigns all of its Commitment and Loans pursuant to Section 10.10(b), such Issuing Bank may, upon 30 days’ prior written notice to the Company, the Administrative Agent, and the Lenders, resign as an Issuing Bank. In such event, the Company may, with the approval of the Administrative Agent and the acceptance of the duties of an Issuing Bank by the Lender so requested, request that another Lender serve as Issuing Bank under this Agreement; provided, however, that the absence of any successor Issuing Bank shall not affect the resignation of the resigning Issuing Bank. Any resigning Issuing Bank shall retain all the rights, powers, privileges and duties of an Issuing Bank under this Agreement with respect to all Letters of Credit outstanding as of the effective date of its resignation and all Reimbursement Obligations with respect thereto (including the right to require the Lenders to make Loans or fund risk participations in Reimbursement Obligations pursuant to Section 2.12). Upon the appointment of any successor Issuing Bank (i) such successor Issuing Bank shall succeed to and become vested with all of the rights, powers, privileges and duties of an Issuing Bank under this Agreement, and (ii) such successor Issuing Bank shall issue Letters of Credit in substitution for the Letters of Credit, if any, previously issued by the resigning Issuing Bank that are outstanding at the time of such succession or make other arrangements satisfactory to the resigning Issuing Bank to effectively assume the obligations of the resigning Issuing Bank with respect to such Letters of Credit.

Section 9.8. Sub-Agent. The Sub-Agent has been designated under this Agreement to carry out certain duties of the Administrative Agent as described herein. The Sub-Agent shall be

subject to each of the obligations in this Agreement to be performed by the Sub-Agent, and each of the Company and the Lenders agrees that the Sub-Agent shall be entitled to exercise each of the rights and shall be entitled to each of the benefits of the Administrative Agent under this Agreement as relate to the performance of its obligations hereunder.

Section 9.9. No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Co-Lead Arrangers, Co-Book Running Managers, Syndication Agent or Co-Documentation Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in their capacity, as applicable, as the Administrative Agent, the Collateral Agent, a Lender or an Issuing Bank.

ARTICLE 10

MISCELLANEOUS.

Section 10.1. No Waiver. No delay or failure on the part of the Administrative Agent, any Lender, the Swingline Lender or any Issuing Bank, or on the part of the holder or holders of any Notes, in the exercise of any power, right or remedy under any Credit Document shall operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power, right or remedy. To the fullest extent permitted by applicable law, the powers, rights and remedies under the Credit Documents of the Administrative Agent, the Lenders, the Issuing Banks and the Swingline Lender and the holder or holders of any Notes are cumulative to, and not exclusive of, any powers, rights or remedies any of them would otherwise have.

Section 10.2. Non-Business Day. Subject to Section 2.4, if any payment of principal or interest on any portion of any Loan, any Reimbursement Obligation, or any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such portion of any Loan, any Reimbursement Obligation, or other Obligation bears for the period prior to maturity shall continue to accrue in the manner set forth herein on such Obligation from the stated due date thereof to the next succeeding Business Day, on which the same shall instead be payable.

Section 10.3. Documentary Taxes. The Company agrees that it will pay (or cause the applicable Designated Borrower to pay) any documentary, stamp or similar taxes payable with respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed irrespective of when such assessment is made, other than any such taxes imposed as a result of any transfer of an interest in a Credit Document. Each Lender, each Issuing Bank and the Swingline Lender that determines to seek compensation under this Section 10.3 shall give written notice to the Company and, in the case of a Lender, an Issuing Bank or the Swingline Lender other than the Administrative Agent, the Administrative Agent of the circumstances that entitle such Lender, such Issuing Bank or the Swingline Lender to such compensation no later than ninety (90) days after such Lender, such Issuing Bank or the Swingline Lender receives actual notice or obtains actual knowledge of the law, rule, order or interpretation or occurrence

of another event giving rise to a claim hereunder. In any event, no Borrower shall have any obligation to pay any amount with respect to claims accruing prior to the 90th day preceding such written demand.

Section 10.4. Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any Borrower has any Obligation hereunder or any Commitment hereunder is in effect.

Section 10.5. Survival of Indemnities. All indemnities and all provisions relative to reimbursement to the Lenders, the Swingline Lender and the Issuing Banks of amounts sufficient to protect the yield of the Lenders, the Swingline Lender and the Issuing Banks with respect to the Loans and the L/C Obligations, including, but not limited to, Section 2.11, Section 2.15, Section 3.3, Section 7.6, Section 8.3, Section 10.3, and Section 10.13 hereof, shall, subject to Section 8.3(c), survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations and, with respect to any Lender, any Issuing Bank or the Swingline Lender, any replacement by the Company of such Lender pursuant to the terms hereof, in each case for a period of one (1) year.

Section 10.6. Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of, and throughout the continuance of, any Event of Default, each Lender, each Issuing Bank and the Swingline Lender and each subsequent holder of any Note is hereby authorized by the Borrowers at any time or from time to time, without prior notice to any Borrower or any other Person, any such prior notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts, and in whatever currency denominated) and any other Indebtedness at any time owing by that Lender, the Swingline Lender or that Issuing Bank or that subsequent holder to or for the credit or the account of a Borrower, whether or not matured, against and on account of the due and unpaid obligations and liabilities of such Borrower to that Lender, the Swingline Lender or that Issuing Bank or that subsequent holder under the Credit Documents, irrespective of whether or not that Lender, the Swingline Lender or that Issuing Bank or that subsequent holder shall have made any demand hereunder. Each Lender, the Swingline Lender or each Issuing Bank shall promptly give notice to the Company of any action taken by it under this Section 10.6, provided that any failure of such Lender, the Swingline Lender or such Issuing Bank to give such notice to the Company shall not affect the validity of such setoff. Each Lender, the Swingline Lender and each Issuing Bank agrees with each other Lender, the Swingline Lender and each other Issuing Bank a party hereto that if such Lender, the Swingline Lender or such Issuing Bank receives and retains any payment, whether by setoff or application of deposit balances or otherwise, in respect of the Loans or L/C Obligations in excess of its ratable share of payments on all such Obligations then owed to the Lenders, the Swingline Lender and the Issuing Banks hereunder, then such Lender, the Swingline Lender or such Issuing Bank shall purchase for cash at face value, but without recourse, ratably from each of the other Lenders such amount of the Loans and L/C Obligations and participations therein held by each such other Lender, Swingline Lender or Issuing Bank as shall be necessary to cause such Lender, Swingline Lender or such Issuing Bank

to share such excess payment ratably with all the other Lenders, the Swingline Lender and the Issuing Banks; provided, however, that if any such purchase is made by any Lender, Swingline Lender or any Issuing Bank, and if such excess payment or part thereof is thereafter recovered from such purchasing Lender, Swingline Lender or Issuing Bank, the related purchases from the other Lenders, Swingline Lender or the Issuing Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest.

Section 10.8. Counterparts. This Agreement may be executed in any number of counterparts, and by the different parties on different counterpart signature pages, each of which when executed shall be deemed an original, but all such counterparts taken together shall constitute one and the same Agreement.

Section 10.9. Successors and Assigns. This Agreement shall be binding upon the Borrowers, each of the Lenders, the Issuing Banks, the Swingline Lender, the Administrative Agent, the Other Agents, and their respective successors and assigns, and shall inure to the benefit of the Borrowers, each of the Lenders, the Issuing Banks, the Swingline Lender, the Administrative Agent, the Other Agents, and their respective successors and assigns, including any subsequent holder of any Note; provided, however, no Borrower may assign any of its rights or obligations under this Agreement or any other Credit Document without the written consent of all Lenders, the Issuing Banks, the Swingline Lender, the Administrative Agent and the Other Agents, and the Administrative Agent and the Other Agents may not assign any of their respective rights or obligations under this Agreement or any Credit Document except in accordance with Article 9 and no Lender or Issuing Bank may assign any of its rights or obligations under this Agreement or any other Credit Document except in accordance with Section 10.10.

Section 10.10. Sales and Transfers of Borrowing and Notes; Participations in Borrowings and Notes.

(a) Any Lender may, without the consent of, or notice to, the Company and the Administrative Agent, at any time sell to one or more commercial banking or other financial or lending institutions (“Participants”) participating interests in any Commitment of such Lender hereunder, provided that no Lender may sell any participating interests (other than in the case of affiliates of such Lender) in any such Commitment hereunder without also selling to such Participant the appropriate pro rata share of all such Lender’s Commitment, and provided further that no Lender shall transfer, grant or assign any participation under which the Participant shall

have rights to vote upon or to consent to any matter to be decided by the Lenders or the Required Lenders hereunder or under any other Credit Document or to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) increase the amount of such Lender’s Commitment and such increase would affect such Participant, (ii) reduce the principal of, or interest on, any of such Lender’s Borrowings, or any fees or other amounts payable to such Lender hereunder and such reduction would affect such Participant, (iii) postpone any date fixed for any scheduled payment of principal of, or interest on, any of such Lender’s Borrowings, or any fees or other amounts payable to such Lender hereunder and such postponement would affect such Participant, or (iv) release any collateral security for any Obligation, except as otherwise specifically provided in any Credit Document. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement, the Borrowers and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and such Lender shall retain the sole right to enforce the obligations of the Borrowers under any Credit Document. Each Borrower agrees that if amounts outstanding under this Agreement and the Notes shall have been declared or shall have become due and payable in accordance with Section 7.2 or 7.3 upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that such right of setoff shall be subject to the obligation of such Participant to share with the Lenders, and the Lenders agree to share with such Participant, as provided in Section 10.6. Each Borrower also agrees that each Participant shall be entitled to the benefits of and have the obligations under Sections 2.11, 2.15, 3.3 and 8.3 with respect to its participation in the Commitments and the Borrowings outstanding from time to time, provided that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred if no participation had been transferred and provided, further, that Sections 8.3(c) and 8.6 shall apply to the transferor Lender with respect to any claim by any Participant pursuant to Section 2.11, 2.15, 3.3 or 8.3 as fully as if such claim was made by such Lender. Anything herein to the contrary notwithstanding, no Borrower shall, at any time, be obligated to pay to any Lender any sum in excess of the sum such Borrower would have been obligated to pay to such Lender hereunder if such Lender had not sold any participation in its rights and obligations under this Agreement or any other Credit Document.

(b) Any Lender may at any time sell to (i) any of such Lender’s affiliates or to any other Lender or any affiliate thereof that, in each case, is a commercial banking or other financial or lending institution not subject to Regulation T of the Board of Governors of the Federal Reserve System, or (ii) with the prior written consent (which shall not be unreasonably withheld or delayed) of the Administrative Agent, the Swingline Lender, the Issuing Banks and if no Event of Default has occurred and is continuing, the Company, to one or more commercial banking or other financial or lending institutions not subject to Regulation T of the Board of Governors of the Federal Reserve System (any of (i) or (ii), a “Purchasing Lender”), all or any part of its rights and obligations under this Agreement and the other Credit Documents, pursuant

to an Assignment Agreement in the form attached as Exhibit 10.10, executed by such Purchasing Lender and such transferor Lender (and, in the case of a Purchasing Lender which is not then a Lender or an affiliate thereof, by the Company and the Administrative Agent) and delivered to the Administrative Agent; provided that each such sale to a Purchasing Lender (other than an existing Lender) shall be in the Dollar Equivalent amount of $5,000,000 or more, or if in a lesser amount or if as a result of such sale the sum of the unfunded Commitment of such Lender plus the aggregate principal amount of such Lender’s Loans and participations in Letters of Credits would be less than the Dollar Equivalent amount of $5,000,000 (calculated as hereinafter set forth), such sale shall be of all of such Lender’s rights and obligations under this Agreement and all of the other Credit Documents payable to it to one Purchasing Lender. Notwithstanding the requirement of the Company’s consent set forth above, but subject to all of the other terms and conditions of this Section 10.10(b), any Lender may sell to one or more commercial banking or other financial or lending institutions not subject to Regulation T of the Board of Governors of the Federal Reserve System, all or any part of their rights and obligations under this Agreement and the other Credit Documents with only the consent of the Administrative Agent and the Issuing Banks (which shall not be unreasonably withheld or delayed) if an Event of Default shall have occurred and be continuing. Upon such execution, delivery and acceptance, from and after the effective date of the transfer determined pursuant to such Assignment Agreement, (x) the Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Lender hereunder with a Commitment as set forth herein and (y) the transferor Lender thereunder shall, to the extent provided in such Assignment Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of a transferor Lender’s rights and obligations under this Agreement, such transferor Lender shall cease to be a party hereto). Such Assignment Agreement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of Commitments and Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement, the Notes and the other Credit Documents. On or prior to the effective date of the transfer determined pursuant to such Assignment Agreement, the applicable Borrower, at its own expense, shall upon reasonable notice from the Administrative Agent execute and deliver to the Administrative Agent in exchange for any surrendered Note, a new Note as appropriate to the order of such Purchasing Lender in an amount equal to the Commitments assumed by it pursuant to such Assignment Agreement, and, if the transferor Lender has retained a Commitment or Borrowing hereunder, a new Note to the order of the transferor Lender in an amount equal to the Commitments or Borrowings retained by it hereunder. Such new Notes shall be dated the Initial Availability Date and shall otherwise be in the form of the Notes replaced thereby. The Notes surrendered by the transferor Lender shall be returned by the Administrative Agent to the Company marked “cancelled.”

(c) Upon its receipt of an Assignment Agreement executed by a transferor Lender and a Purchasing Lender (and, in the case of a Purchasing Lender that is not then a Lender or an affiliate thereof, by the Administrative Agent and, to the extent required by Section 10.10(b), by the Company), together with payment by the transferor Lender to the Administrative Agent hereunder of a registration and processing fee of $3,500 (unless the Company is replacing such Lender pursuant to the terms hereof, in which event such fee shall be paid by the Company), the Administrative Agent shall (i) promptly accept such Assignment

Agreement, and (ii) on the effective date of the transfer determined pursuant thereto give notice of such acceptance and recordation to the Lenders and the Company. The Company shall not be responsible for such registration and processing fee or any costs or expenses incurred by any Lender, any Purchasing Lender or the Administrative Agent in connection with such assignment except as provided above.

(d) If, pursuant to this Section 10.10 any interest in this Agreement or any Loan or Note is transferred to any transferee which is organized under the laws of any jurisdiction other than the United States of America or any State thereof, the transferor Lender shall cause such transferee, concurrently with the effectiveness of such transfer, (i) to represent to the transferor Lender (for the benefit of the transferor Lender, the Administrative Agent and the Company) that under applicable law and treaties no taxes will be required to be withheld by the Administrative Agent, any Borrower or the transferor Lender with respect to any payments to be made to such transferee in respect of the Loans or the L/C Obligations, (ii) to furnish to the transferor Lender (and, in the case of any Purchasing Lender, the Administrative Agent and the Company) two duly completed and signed copies of either U.S. Internal Revenue Service Form W-8BEN or U.S. Internal Revenue Service Form W-8ECI or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities (wherein such transferee claims entitlement to complete exemption from U.S. federal withholding tax on all interest payments hereunder), and (iii) to agree (for the benefit of the transferor Lender, the Administrative Agent and the Company) to provide the transferor Lender (and, in the case of any Purchasing Lender, the Administrative Agent and the Company) new forms as contemplated by Section 3.3(b) upon the expiration or obsolescence of any previously delivered form and comparable statements in accordance with applicable U.S. laws and regulations and amendments duly executed and completed by such transferee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption.

(e) Notwithstanding any other provisions of this Section 10.10, no transfer or assignment of the interests of any Lender hereunder or any grant of participations therein shall be permitted if such transfer, assignment or grant would require any Borrower to file a registration statement with the SEC or to qualify the Loans, the Notes or any other Obligations under the securities laws of any jurisdiction.

Section 10.11. Amendments, Waivers and Consents. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Company, (b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent, the Other Agents, the Swingline Lender or any Issuing Bank are affected thereby, the Administrative Agent, the Other Agents, the Swingline Lender or such Issuing Bank, as the case may be, provided that:

(i) no amendment or waiver shall (A) (other than in accordance with Section 2.14) increase the Revolving Credit Commitment Amount without the consent of all Lenders or increase any Commitment of any Lender without the consent of such Lender, or (B) (other than in accordance with Section 2.16) postpone the Commitment Termination Date or Maturity Date without the consent of all Lenders, or reduce the amount of or postpone the date for any scheduled payment of any principal of or interest (including, without limitation, any reduction in the rate of interest unless such reduction

is otherwise provided herein) on any Loan or Reimbursement Obligation or of any fee payable hereunder, without the consent of each Lender owed any such Obligation, or (C) release any Collateral for any Collateralized Obligations (other than as provided in accordance with Section 7.4) without the consent of all Lenders, (D) release the NDC Guaranty (except as expressly provided for therein), during any period that there is a Designated Borrower, release the Company Guaranty (except as expressly provided for therein), or modify the provisions of Article 4 hereof without the consent of all Lenders, (E) change any provision requiring ratable funding or sharing of payments without the consent of all Lenders or (F) amend or waive this Section 10.11, the definition herein of “Required Lenders” or the number of Lenders required to take any action under any other provision of the Credit Documents without the consent of all Lenders; and

(ii) no amendment or waiver shall, unless signed by each Lender, change the provisions of this Section 10.11 or the definition of Required Lenders or the number of Lenders required to take any action under any other provision of the Credit Documents.

Section 10.12. Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement.

Section 10.13. Legal Fees, Other Costs and Indemnification. The Company, upon demand by the Administrative Agent, agrees to pay all reasonable out-of-pocket costs and expenses of the Administrative Agent (including, without limitation, the reasonable fees and disbursements of legal counsel to the Administrative Agent) in connection with the preparation and execution of the Credit Documents (not to exceed such amount previously agreed to by the Administrative Agent), and any amendment, waiver or consent related thereto, whether or not the transactions contemplated therein are consummated. The Company further agrees to indemnify and hold harmless each Lender, Issuing Bank, the Swingline Lender, the Administrative Agent, the Other Agents, and their respective directors, officers, employees and attorneys (collectively, the “Indemnified Parties”), against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all reasonable attorneys’ fees and other reasonable expenses of litigation or preparation therefor, whether or not such Indemnified Party is a party thereto) which any of them may pay or incur as a result of (a) any action, suit or proceeding by any third party or Governmental Authority against such Indemnified Party and relating to any Credit Document, the Loans, any Letter of Credit, or the application or proposed application by any of a Borrower of the proceeds of any Loan or use of any Letter of Credit, REGARDLESS OF WHETHER SUCH CLAIMS OR ACTIONS ARE FOUNDED IN WHOLE OR IN PART UPON THE ALLEGED SIMPLE OR CONTRIBUTORY NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES AND/OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR ATTORNEYS, (b) any investigation of any third party or any Governmental Authority involving any Lender (as a lender hereunder), any Issuing Bank, the Swingline Lender or the Administrative Agent or the Other Agents (in such capacity hereunder) and related to any use made or proposed to be made by a Borrower of the proceeds of any Loan, or use of any Letter of Credit or any transaction financed or to be financed in whole or in part, directly or indirectly with the proceeds of any Loan or Letter of Credit, and (c) any investigation of any third party or any Governmental Authority, litigation or proceeding involving any Lender (as a lender hereunder), the Swingline Lender (as a swingline lender

hereunder), any Issuing Bank (as an issuer of Letters of Credit hereunder) or the Administrative Agent or the Other Agents (in such capacity hereunder) and related to any environmental cleanup, audit, compliance or other matter relating to any Environmental Law or the presence of any Hazardous Material (including, without limitation, any losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under any Environmental Law) with respect to the Company, regardless of whether caused by, or within the control of, the Company; provided, however, that the Company shall not be obligated to indemnify any Indemnified Party for any of the foregoing arising out of such Indemnified Party’s gross negligence, willful misconduct, violation of law or willful breach of its obligations hereunder, as determined pursuant to a judgment of a court of competent jurisdiction or as expressly agreed in writing by such Indemnified Party. The Company, upon demand by the Administrative Agent, the Other Agents, a Lender, the Swingline Lender or a Issuing Bank at any time, shall reimburse such Agent, Lender, Swingline Lender or Issuing Bank for any reasonable legal or other expenses incurred in connection with investigating or defending against any of the foregoing, except if the same is excluded from indemnification pursuant to the provisions of the preceding sentence. Each Indemnified Party agrees to contest any indemnified claim if requested by the Company, in a manner reasonably directed by the Company, with counsel selected by the Indemnified Party and approved by the Company, which approval shall not be unreasonably withheld or delayed. Any Indemnified Party that proposes or intends to settle or compromise any such indemnified claim shall give the Company written notice of the terms of such settlement or compromise reasonably in advance of settling or compromising such claim or proceeding and shall obtain the Company’s prior written consent thereto, which consent shall not be unreasonably withheld or delayed; provided that the Indemnified Party shall not be restricted from settling or compromising any such claim if (i) the Indemnified Party waives its right to indemnity from the Company in respect of such claim and such settlement or compromise does not materially increase the Company’s liability pursuant to this Section 10.13 to any related party of such Indemnified Party, (ii) an Event of Default as described in Section 7.1(a), (b) (as a result of a default under Section 6.16), (f) or (g) or has occurred and is continuing or (iii) the Indemnified Party reasonably believes the Company will not be able to satisfy the full amount of such claim and the Company has failed to provide sufficient collateral to the Indemnified Party to secure the value of such claim.

Section 10.15. Confidentiality. Each of the Agents, the Issuing Banks, the Swingline Lender and Lenders agree to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to their respective affiliates and to prospective Purchasing Lenders and Participants and their respective directors, officers, employees and agents, including accountants, legal counsel and other advisors who have reason to use such Information in connection with the evaluation of the transactions contemplated by this Agreement (subject to similar confidentiality provisions as provided herein) solely for purposes of evaluating such Information, (ii) to the extent requested by any regulatory authority, (iii) to the extent required by applicable law or regulation or by any subpoena or similar legal process, (iv) in connection with the exercise of any remedies hereunder or any proceedings relating to this Agreement or the other Credit Documents, (v) with the consent of the Company, or (vi) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section 10.15, or (y) becomes available on a non-confidential basis from a source other than the Company or its affiliates, or the Lenders or their respective affiliates, excluding any Information from such source which, to the actual knowledge of the Agent, Issuing Bank, the Swingline Lender or Lender receiving such Information, has been disclosed by such source in violation of a duty of confidentiality to the Company. For purposes hereof, “Information” means all information received by the Lenders, the Swingline Lenders or the Issuing Banks from the Company relating to the Company or its business, other than any such information that is available to the Lenders, the Swingline Lender or the Issuing Banks on a non-confidential basis prior to disclosure by the Company, excluding any Information from a source which, to the actual knowledge of the Agent, Issuing Bank, Swingline Lender or Lender receiving such Information, has been disclosed by such source in violation of a duty of confidentiality to the Company. The Agents, the Issuing Banks, the Swingline Lender and the Lenders shall be considered to have complied with their respective obligations if they have exercised the same degree of care to maintain the confidentiality of such Information as they would accord their own confidential information.

Section 10.16. Effectiveness. This Agreement shall become effective on the date (the “Effective Date”) on which the Company, the Administrative Agent, the Swingline Lender and each Lender have signed and delivered to the Administrative Agent a counterparty signature page hereto (including by facsimile or other electronic means) or the Administrative Agent has received a facsimile notice that such a counterpart has been signed and mailed to the Administrative Agent.

Section 10.17. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any

such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 10.18. Currency Conversion. All payments of Obligations under this Agreement, the Notes or any other Credit Document shall be made in U.S. Dollars, except for Loans funded, or Reimbursement Obligations with respect to Letters of Credit issued, in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner, which shall be repaid, including interest thereon, in the applicable currency. If any payment of any Obligation, whether through payment by any Credit Party or the proceeds of any collateral, shall be made in a currency other than the currency required hereunder, such amount shall be converted into the currency required hereunder at the rate determined by the Administrative Agent or Issuing Bank, as applicable, as the rate quoted by it in accordance with methods customarily used by such Person for such or similar purposes as the spot rate for the purchase by such Person of the required currency with the currency of actual payment through its principal foreign exchange trading office (including, in the case of the Administrative Agent, the Sub-Agent) at approximately 11:00 A.M. (local time at such office) two Business Days prior to the effective date of such conversion, provided that the Administrative Agent or Issuing Bank, as applicable, may obtain such spot rate from another financial institution actively engaged in foreign currency exchange if the Administrative Agent or Issuing Bank, as applicable, does not then have a spot rate for the required currency. The parties hereto hereby agree, to the fullest extent that they may effectively do so under applicable law, that (i) if for the purposes of obtaining any judgment or award it becomes necessary to convert from any currency other than the currency required hereunder into the currency required hereunder any amount in connection with the Obligations, then the conversion shall be made as provided above on the Business Day before the day on which the judgment or award is given, (ii) in the event that there is a change in the applicable conversion rate prevailing between the Business Day before the day on which the judgment or award is given and the date of payment, the Company will pay (or cause the applicable Designated Borrower to pay) to the Administrative Agent, for the benefit of the Lenders, such additional amounts (if any) as may be necessary, and the Administrative Agent, on behalf of the Lenders, will pay to the applicable Borrower such excess amounts (if any) as result from such change in the rate of exchange, to assure that the amount paid on such date is the amount in such other currency, which when converted at the conversion rate described herein on the date of payment, is the amount then due in the currency required hereunder, and (iii) any amount due from a Borrower under this Section 10.18 shall be due as a separate debt and shall not be affected by judgment or award being obtained for any other sum due. For the avoidance of doubt, the parties affirm and agree that neither the fixing of the conversion rate of Pounds or Kroners against the Euro as a single currency, in accordance with the applicable treaties establishing the European Economic Community and the European Union, as the case may be, in each case, as amended from time to time, nor the conversion of the Obligations under this Agreement from Pounds or Kroners into Euros will be a reason for early termination or revision of this Agreement or prepayment of any amount due under this Agreement or create any liability of any party towards any other party for any direct or consequential loss arising from any of these events. As of the date that Pounds or Kroners are no longer the lawful currency of the United Kingdom or Norway, as the case may be, all funding and payment Obligations to be made in such affected currency under this Agreement shall be satisfied in Euros. If, in relation to the currency of any member state of the European Union that adopts the Euro as its lawful currency, the basis of accrual of interest expressed in this Agreement in respect of that currency

shall be inconsistent with any convention or practice in the London interbank market for the basis of accrual of interest in respect of the Euro, such expressed basis shall be replaced by such convention or practice with effect from the date on which such member state adopts the Euro as its lawful currency; provided that if any Borrowing in the currency of such member state is outstanding immediately prior to such date, such replacement shall take effect, with respect to such Borrowing, at the end of the then current Interest Period.

Section 10.19. Exchange Rates.

(a) Determination of Exchange Rates. Not later than 2:00 P.M. (London time) on each Calculation Date, if any L/C Obligations are outstanding on such date in a currency other than U.S. Dollars, the applicable Issuing Bank shall determine the Exchange Rate as of such Calculation Date for all such L/C Obligations outstanding as of such date with respect to all Letters of Credit issued by such Issuing Bank or its affiliates (the “Issuing Bank Exchange Rate”) and give prompt notice thereof to the Administrative Agent. No later than 4:00 P.M. (London time) on each such Calculation Date, (i) the Administrative Agent shall (i) determine the Exchange Rate (other than the Issuing Bank Exchange Rate, if applicable) as of such Calculation Date with respect to Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and Kroner, and (ii) give notice thereof, together with notice of the applicable Issuing Bank Exchange Rate, if applicable, to the Lenders and the Company. The Exchange Rates so determined shall become effective on the first Business Day immediately following the relevant Calculation Date (a “Reset Date”), shall remain effective until the next succeeding Reset Date, and shall for all purposes of this Agreement (other than Section 10.18 or any other provision expressly requiring the use of a current Exchange Rate) be the Exchange Rates employed in determining the Dollar Equivalent of any amounts of Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner. Notwithstanding anything contained herein to the contrary, if any Issuing Bank fails to timely deliver notice of its Issuing Bank Exchange Rate to the Administrative Agent pursuant to the provisions of this Section 10.19, the Administrative Agent may determine such rate in accordance with the definition of Exchange Rate and shall have no liability to such Issuing Bank for such determination.

(b) Notice of Foreign Currency Loans and Letters of Credit. Not later than 2:00 P.M. (London time) on each Reset Date and each date on which Loans and/or Letters of Credit denominated in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and/or Kroner are made or issued, if any such L/C Obligations are outstanding on such date, the applicable Issuing Bank shall determine its Issuing Bank Exchange Rate as of such date, if applicable, and give prompt notice thereof to the Administrative Agent. Not later than 5:00 P.M. (New York time) on each Reset Date and each date on which Loans and/or Letters of Credit denominated in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and/or Kroner are made or issued, the Administrative Agent shall (i) determine the Dollar Equivalent of the aggregate principal amounts of the Loans and L/C Obligations denominated in such currencies (after giving effect to any Loans and/or Letters of Credit denominated in such currencies being made, issued, repaid, or cancelled or reduced on such date), (ii) notify the Lenders and the Company of the results of such determination and (iii) notify the Issuing Bank, if applicable, that the conditions to issuance set forth in Section 2.12(a) are satisfied.

Section 10.20. Change in Accounting Principles, Fiscal Year or Tax Laws. If (i) any change in accounting principles from those used in the preparation of the financial statements of the Company referred to in Section 5.9 is hereafter occasioned by the promulgation of rules, regulations, pronouncements and opinions by or required by the Financial Accounting Standards Board or the American Institute of Certified Public Accounts (or successors thereto or agencies with similar functions), and such change materially affects the calculation of any component of any financial covenant, standard or term found in this Agreement, or (ii) there is a material change in federal, state or foreign tax laws which materially affects any of the Company and its Subsidiaries’ ability to comply with the financial covenants, standards or terms found in this Agreement, the Company and the Lenders agree to enter into negotiations in order to amend such provisions (with the agreement of the Required Lenders or, if required by Section 10.11, all of the Lenders) so as to equitably reflect such changes with the desired result that the criteria for evaluating any of the Company’s and its Subsidiaries’ financial condition shall be the same after such changes as if such changes had not been made. Unless and until such provisions have been so amended, the provisions of this Agreement shall govern.

Section 10.21. Final Agreement. The Credit Documents constitute the entire understanding among the Credit Parties, the Lenders, the Swingline Lender, the Issuing Banks, and the Administrative Agent and supersede all earlier or contemporaneous agreements, whether written or oral, concerning the subject matter of the Credit Documents. THIS WRITTEN AGREEMENT TOGETHER WITH THE OTHER CREDIT DOCUMENTS REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 10.22. Officer’s Certificates. It is not intended that any certificate of any officer or director of any Credit Party delivered to the Administrative Agent or any Lender pursuant to this Agreement shall give rise to any personal liability on the part of such officer or director.

Section 10.23. Effect of Inclusion of Exceptions. It is not intended that the specification of any exception to any covenant herein shall imply that the excepted matter would, but for such exception, be prohibited or required.

Section 10.24. Margin Stock. Each of the Lenders, the Swingline Lender and Issuing Banks hereby represents to the other Lenders, Swingline Lender and Issuing Banks that it is not relying on margin stock as collateral in extending or maintaining any Loan or Letter of Credit.

Section 10.25. Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the requirements of 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 Borrowers and other information that will allow such Lender or the Administrative Agent, as applicable, to identify each Borrower in accordance with the Patriot Act. Each Borrower shall provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lenders in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed and delivered by their duly authorized officers as of the day and year first above written.

EXHIBIT 1.1

GUARANTY AGREEMENT

THIS GUARANTY AGREEMENT (this “Guaranty”), dated as of March 15, 2007 is made by Noble Drilling Corporation, a Delaware corporation (the “Guarantor”), in favor of (i) the Lenders (as defined in the Credit Agreement) (as hereinafter defined), (ii) Citibank, N.A., in its capacity as Administrative Agent (as defined in the Credit Agreement), (iii) Citibank, N.A., in its capacity as the Swingline Lender (as defined in the Credit Agreement), (iv) Other Agents (as defined in the Credit Agreement) and (v) the Issuing Banks (as defined in the Credit Agreement) (the Lenders, the Administrative Agent, the Other Agents, the Swingline Lender and the Issuing Banks are each individually referred to herein as a “Guaranteed Party”, and collectively, as the “Guaranteed Parties”);

WITNESSETH:

WHEREAS, Noble Corporation, a Cayman Islands exempted company limited by shares (the “Company”), the Lenders, the Administrative Agent, the Swingline Lender and the Issuing Banks are parties to a certain Revolving Credit Agreement dated as of March 15, 2007 (as the same may hereafter be amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; terms defined therein and not otherwise defined herein being used herein as therein defined);

WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding capital stock or other equity interests of the Guarantor;

WHEREAS, consummation of the transactions pursuant to the Credit Agreement have facilitated expansion and enhanced the overall financial strength and stability of the Company’s entire corporate group, including the Guarantor; and

WHEREAS, it is a requirement under Section 4.1(a) of the Credit Agreement, as a condition to Loans and Letters of Credit, that the Guarantor execute and deliver this Guaranty, and the Guarantor desires to execute and deliver this Guaranty to satisfy such requirement;

NOW, THEREFORE, in consideration of the premises and in order to satisfy the requirements of the Credit Agreement, and for other good and valuable consideration, the Guarantor hereby agrees as follows:

SECTION 1. Guaranty. The Guarantor hereby, irrevocably and unconditionally, guarantees the punctual payment when due, in lawful money of the United States of America or in another currency as provided for in Section 3.2(a) of the Credit Agreement (the “Obligation Currency”), whether at stated maturity, by acceleration or otherwise, of the Loans, L/C Obligations, and all other Obligations owing by the Company to the Lenders, the Administrative Agent, the Swingline Lender, the Issuing Banks and Other Agents, or any of them, under the Credit Agreement, the Notes, and the other Credit Documents, including all renewals, extensions, modifications and refinancings thereof, now or hereafter

owing, whether for principal, interest, fees, expenses, indemnities, reimbursement obligations or otherwise, and any and all reasonable out-of-pocket expenses (including reasonable attorneys’ fees and expenses) incurred by the Lenders or the Administrative Agent in enforcing any rights under this Guaranty (collectively, the “Guaranteed Obligations”), including without limitation, all interest which, but for the filing of a petition in bankruptcy, would accrue on any principal portion of the Guaranteed Obligations. Any and all payments by the Guarantor hereunder shall be made in the Obligation Currency free and clear of and without deduction for any set-off, counterclaim, or withholding so that, in each case, each Guaranteed Party will receive, after giving effect to any Indemnified Taxes (as such term is defined in the Credit Agreement), the full amount, in the Obligation Currency, that it would otherwise be entitled to receive with respect to the Guaranteed Obligations (but without duplication of amounts for Indemnified Taxes already included in the Guaranteed Obligations). The Guarantor acknowledges and agrees that this is a guarantee of payment when due, and not of collection, and that this Guaranty may be enforced up to the full amount of the Guaranteed Obligations without proceeding against the Company, against any security for the Guaranteed Obligations, against any other Person or under any other guaranty covering any portion of the Guaranteed Obligations.

SECTION 2. Guaranty Absolute. The Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Guaranteed Party with respect thereto. The liability of the Guarantor under this Guaranty shall be absolute and unconditional in accordance with its terms and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever, including, without limitation, the following (whether or not the Guarantor consents thereto or has notice thereof):

(a) any change in the time, place or manner of payment of, or in any other term of, all or any of the Guaranteed Obligations, any waiver, indulgence, renewal, extension, amendment or modification of or addition, consent or supplement to or deletion from or any other action or inaction under or in respect of the Credit Agreement or the other Credit Documents, or any other documents, instruments or agreements relating to the Guaranteed Obligations or any other instrument or agreement referred to therein or any assignment or transfer of any thereof;

(b) any lack of validity or enforceability of the Credit Agreement or the other Credit Documents, or any other document, instrument or agreement referred to therein or any assignment or transfer of any thereof;

(c) any furnishing to the Guaranteed Parties of any additional security or additional guaranty for the Guaranteed Obligations, or any sale, exchange, release or surrender of, or realization on, any security or guaranty for the Guaranteed Obligations;

(d) any settlement or compromise of any of the Guaranteed Obligations, any security therefor, or any liability of any other party with respect to the Guaranteed Obligations, or any subordination of the payment of the Guaranteed Obligations to the payment of any other liability of the Company;

-2-

(e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to the Guarantor, the Company or any other Person, or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding;

(f) any nonperfection of any security interest or lien on any collateral, or any amendment or waiver of or consent to departure from any guaranty or security, for all or any of the Guaranteed Obligations;

(g) any application of sums paid by the Company or any other Person with respect to the liabilities of the Company to the Guaranteed Parties, regardless of what liabilities of the Company remain unpaid;

(h) any act or failure to act by any Guaranteed Party which may adversely affect the Guarantor’s subrogation rights, if any, against the Company to recover payments made under this Guaranty; and

(i) any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b) any settlement or compromise of any such claim effected by the Guaranteed Party with any such claimant (including, without limitation, the Company or a trustee in bankruptcy for the Company), then and in such event the Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Credit Agreement, the other Credit Documents, or any other instrument evidencing any liability of the Company, and the Guarantor shall be and remain liable to the Guaranteed Party for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Guaranteed Party.

SECTION 3. Waiver.

SECTION 15. Maximum Obligations. (a) It is the intent of the Guarantor and the Guaranteed Parties that the Guarantor’s maximum obligations hereunder shall be in, but not in excess of:

(i) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy Code on or within one year from the date on which any of the Guaranteed Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against the Guarantor under (A) Section 548 of the Bankruptcy Code or (B) any state fraudulent transfer or fraudulent conveyance act or statute applied in such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or

(ii) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy Code subsequent to one year from the date on which any of the Guaranteed Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against the Guarantor under any state fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or

(iii) in a case or proceeding commenced by or against the Guarantor under any law, statute or regulation other than the Bankruptcy Code (including, without limitation, any other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt, dissolution, liquidation or similar debtor relief laws), the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against the Guarantor under such law, statute or regulation including, without limitation, any state fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding.

value or reasonably equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would render the Guarantor insolvent, or leave the Guarantor with an unreasonably small capital to conduct its business, or cause the Guarantor to have incurred debts (or to have intended to have incurred debts) beyond its ability to pay such debts as they mature, in each case as of the time any of the Guaranteed Obligations are deemed to have been incurred under the Avoidance Provisions and after giving effect to rights of contribution, indemnity and subrogation as between the Guarantor and the Company, the maximum Guaranteed Obligations for which the Guarantor shall be liable hereunder shall be reduced to that amount which, after giving effect thereto, would not cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties), as so reduced, to be subject to avoidance under the Avoidance Provisions. This Section 15(b) is intended solely to preserve the rights of the Guaranteed Parties hereunder to the maximum extent that would not cause the Guaranteed Obligations of the Guarantor to be subject to avoidance under the Avoidance Provisions, and neither the Guarantor nor any other Person shall have any right or claim under this Section 15 as against the Guaranteed Parties that would not otherwise be available to such Person under the Avoidance Provisions.

SECTION 16. Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as the Guarantor may have under applicable law (but subject to Section 4 hereof), the Company agrees that (i) in the event a payment shall be made on behalf of the Company by the Guarantor hereunder, the Company shall indemnify the Guarantor for the full amount of such payment and the Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment, and (ii) in the event any assets of the Guarantor shall be sold to satisfy a claim of any Guaranteed Party hereunder, the Company shall indemnify the Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

SECTION 17. Information. The Guarantor assumes all responsibility for being and keeping itself informed of the Company’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that the Guarantor assumes and incurs hereunder, and agrees that none of the Guaranteed Parties will have any duty to advise any of the Guarantor of information known to it or any of them regarding such circumstances or risks.

SECTION 18. Representations and Warranties. The Guarantor represents and warrants to each Guaranteed Party that all representations and warranties relating to it or any of its Subsidiaries contained in Article 5 of the Credit Agreement are true and correct in all material respects.

SECTION 19. Survival of Agreement. All agreements, representations and warranties made herein shall survive the execution and delivery of this Guaranty, the Credit Agreement, the making of the Loans, the execution and delivery of the Notes and the other Credit Documents and the issuance of Letters of Credit.

SECTION 20. Counterparts. This Guaranty and any amendments, waivers, consents or supplements may be executed in any number of counterparts and by

-8-

different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument.

SECTION 21. Currency of Payment. All payments to be made by the Guarantor hereunder shall be made in the applicable currency as provided in Section 10.18 of the Credit Agreement and, in the case of any required conversion of any currency, shall be determined, and the related amounts calculated, in the manner provided in Section 10.18 of the Credit Agreement.

SECTION 22. Termination of Guaranty. In addition to termination upon payment in full of all of the Guaranteed Obligations (subject to the last sentence of Section 2 hereof), all obligations of the Guarantor to the Guaranteed Parties hereunder shall terminate upon the delivery by the Company to the Administrative Agent of a certificate stating that (i) the aggregate principal amount of Indebtedness of all Subsidiaries outstanding pursuant to Section 6.11(j) and (k) of the Credit Agreement, including Indebtedness of the Guarantor, is equal to or less than the Subsidiary Debt Basket Amount, (ii) no Senior NDC Notes are outstanding and (iii) no Default or Event of Default has occurred and is continuing. Upon compliance with the foregoing, the Administrative Agent and the Lender shall provide written confirmation of such termination as may be reasonably requested by the Guarantor.

REVOLVING NOTE

(Master Note)


U.S.$		,

FOR VALUE RECEIVED, the undersigned [NOBLE CORPORATION, a Cayman Islands exempted company limited by shares] [DESIGNATED BORROWER] (the “Borrower”), unconditionally promises to pay to the order of (herein, together with any subsequent holder hereof, referred to as the “Lender”) for the account of its applicable Lending Office, at the payment office of the Administrative Agent (as hereinafter defined) on or before the Commitment Termination Date (as defined in the Credit Agreement hereinafter described) the principal sum of DOLLARS (U.S.$ ) or, if less, the aggregate unpaid principal amount of all Revolving Loans made by the Lender to the Borrower pursuant to the Credit Agreement, together with interest accrued thereon, in each case as provided in the Credit Agreement. The Borrower agrees to make payments and any required prepayments of principal on the dates and in the amounts specified in the Credit Agreement in strict accordance with the terms thereof. The Borrower likewise agrees to pay interest on the outstanding principal amount hereof, at such interest rates, payable at such times, and computed in such manner, as are specified in the Credit Agreement in strict accordance with the terms thereof. All remaining principal and accrued interest then outstanding under this Note shall be due and payable in full on the Commitment Termination Date. All payments of principal and interest hereunder in respect of each Revolving Loan shall be made in immediately available funds in the respective currency in which principal and interest on such Revolving Loan are payable as provided in the Credit Agreement.

The Lender shall record all Revolving Loans made by the Lender to the Borrower pursuant to the Credit Agreement, and all payments of principal thereof, and, prior to any transfer hereof, shall endorse such Revolving Loan and payments on the schedule annexed hereto and made a part hereof, or on any continuation thereof which shall be attached hereto and made a part hereof, which endorsement shall constitute prima facie evidence of the accuracy of the information so endorsed; provided, however, that delay or failure of the Lender to make any such endorsement or recordation shall not affect the obligations of the Borrower hereunder or under the Credit Agreement with respect to the Revolving Loans evidenced hereby.

It is the intention of the Lender to conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby or the Revolving Loans represented hereby would be usurious as to the Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to the Lender notwithstanding the other provisions of this Note or the Credit Agreement), then, in that event, notwithstanding anything to the contrary in this Note, the Credit Agreement or any other instrument or agreement entered into in connection with this Note, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under laws applicable to the Lender that is contracted for, taken, reserved, charged or received by the Lender under this Note, the Credit Agreement, or under any of the aforesaid agreements or

instruments entered into in connection with this Note or otherwise shall under no circumstances exceed the Highest Lawful Rate, and any excess shall be credited by the Lender on the principal amount of this Note (or, if the principal amount of this Note shall have been paid in full, refunded by the Lender to the Borrower); and (ii) in the event that the maturity of this Note is accelerated by reason of an election of the holder or holders hereof resulting from any Event of Default under the Credit Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under laws applicable to the Lender may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Note, the Credit Agreement or otherwise shall be automatically canceled by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of this Note (or if the principal amount of this Note shall have been paid in full, refunded by the Lender to the Borrower), and in each case, to the extent permitted by applicable law, the Lender shall not be subject to any of the penalties provided by law for contracting for, taking, reserving, charging or receiving interest in excess of the Highest Lawful Rate.

“Highest Lawful Rate” shall mean the maximum nonusurious interest rate, if any, that any time or from time to time may be contracted for, taken, reserved, charged or received on any Loans, under laws applicable to any of the Lenders which are presently in effect or, to the extent allowed by applicable law, under such laws which may hereafter be in effect and which allow a higher maximum nonusurious interest rate than applicable laws now allow. Determination of the rate of interest for the purpose of determining whether any Loans are usurious under all applicable laws shall be made by amortizing, prorating, allocating, and spreading, in equal parts during the period of the full stated term of the Loans, all interest at any time contracted for, taken, reserved, charged or received from the Borrower in connection with the Loans.

This Note is one of the Revolving Notes referred to in, and is subject to and entitled to the benefits of, that certain Revolving Credit Agreement dated as of March 15, 2007 (as the same may be amended, supplemented, and restated from time to time, the “Credit Agreement”), entered into by and among Noble Corporation, [DESIGNATED BORROWER], the Lender, CITIBANK, N.A., as administrative agent for the Lenders (in such capacity, the “Administrative Agent”) and others. Reference is hereby made to the Credit Agreement for a statement of the prepayment rights and obligations of the Borrower and for a statement of the terms and conditions under which the due date of this Note may be accelerated. Capitalized terms not otherwise defined in this Note that are defined in the Credit Agreement are used in this Note with the respective meanings assigned to such capitalized terms in the Credit Agreement as provided in the Credit Agreement.

Upon the occurrence and during the continuance of any Event of Default as specified in the Credit Agreement, the principal balance hereof and the interest accrued hereon may be declared to be forthwith due and payable in accordance with the Credit Agreement. The Borrower agrees to pay, and indemnify the Lender against any liability for the payment of, all reasonable costs and expenses (including reasonable attorneys’ fees) arising in connection with the enforcement by the Lender of any of its rights under this Note or the Credit Agreement as provided in the Credit Agreement.

-2-

All parties hereto, whether as makers, endorsees, or otherwise, severally waive presentment for prepayment, demand, protest, notice of intent to accelerate, notice of acceleration, notice of dishonor and all other notices whatsoever in respect of this Note. TIME IS OF THE ESSENCE OF THIS NOTE.

THIS NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

IN WITNESS WHEREOF, the Borrower has caused this Note to be executed and delivered by its duly authorized officer as of the date first above written.

The Borrower agrees to make payments and any required prepayments of principal on the dates and in the amounts specified in the Credit Agreement in strict accordance with the terms thereof. The Borrower likewise agrees to pay interest on the outstanding principal amount hereof, at such interest rates, payable at such times, and computed in such manner, as are specified in the Credit Agreement in strict accordance with the terms thereof. All payments of principal and interest hereunder in respect of each Swingline Loan shall be made in immediately available funds in Dollars.

The Lender shall record all Swingline Loans made by the Lender to the Borrower pursuant to the Credit Agreement, and all payments of principal thereof, and, prior to any transfer hereof, shall endorse such Swingline Loan and payments on the schedule annexed hereto and made a part hereof, or on any continuation thereof which shall be attached hereto and made a part hereof, which endorsement shall constitute prima facie evidence of the accuracy of the information so endorsed; provided, however, that delay or failure of the Lender to make any such endorsement or recordation shall not affect the obligations of the Borrower hereunder or under the Credit Agreement with respect to the Swingline Loans evidenced hereby.

It is the intention of the Lender to conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby or the Swingline Loans represented hereby would be usurious as to the Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to the Lender notwithstanding the other provisions of this Note or the Credit Agreement), then, in that event, notwithstanding anything to the contrary in this Note, the Credit Agreement or any other instrument or agreement entered into in connection with this Note, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under laws applicable to the Lender that is contracted for, taken, reserved, charged or received by the Lender under this Note, the Credit Agreement, or under any of the aforesaid agreements or instruments entered into in connection with this Note or otherwise shall under no circumstances

exceed the Highest Lawful Rate, and any excess shall be credited by the Lender on the principal amount of this Note (or, if the principal amount of this Note shall have been paid in full, refunded by the Lender to the Borrower); and (ii) in the event that the maturity of this Note is accelerated by reason of an election of the holder or holders hereof resulting from any Event of Default under the Credit Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under laws applicable to the Lender may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Note, the Credit Agreement or otherwise shall be automatically canceled by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of this Note (or if the principal amount of this Note shall have been paid in full, refunded by the Lender to the Borrower), and in each case, to the extent permitted by applicable law, the Lender shall not be subject to any of the penalties provided by law for contracting for, taking, reserving, charging or receiving interest in excess of the Highest Lawful Rate.

“Highest Lawful Rate” shall mean the maximum nonusurious interest rate, if any, that any time or from time to time may be contracted for, taken, reserved, charged or received on any Loans, under laws applicable to the Lender which are presently in effect or, to the extent allowed by applicable law, under such laws which may hereafter be in effect and which allow a higher maximum nonusurious interest rate than applicable laws now allow. Determination of the rate of interest for the purpose of determining whether any Swingline Loan is usurious under all applicable laws shall be made by amortizing, prorating, allocating, and spreading, in equal parts during the period of the full stated term of such Loan, all interest at any time contracted for, taken, reserved, charged or received from the Borrower in connection with such Loan.

MANDATORY COSTS RATE

1.		The Mandatory Cost is an addition to the interest rate on each Eurocurrency Loan to compensate Lenders for the cost of compliance with (a) the requirements of the Bank of England and/or the Financial Services Authority (or, in either case, any other authority which replaces all or any of its functions) or (b) the requirements of the European Central Bank.

2.		On the first day of each Interest Period (or as soon as possible thereafter) the Administrative Agent shall calculate, as a percentage rate, a rate (the “Additional Cost Rate”) for each Lender, in accordance with the paragraphs set out below. The Mandatory Cost will be calculated by the Administrative Agent as a weighted average of the Lenders’ Additional Cost Rates (weighted in proportion to the percentage participation of each Lender in the relevant Eurocurrency Loan) and will be expressed as a percentage rate per annum.

3.		The Additional Cost Rate for any Lender lending from a Lending Office in a Participating Member State will be the percentage notified by that Lender to the Administrative Agent. This percentage will be certified by that Lender in its notice to the Administrative Agent to be its reasonable determination of the cost (expressed as a percentage of that Lender’s participation in all Eurocurrency Loans made from that Lending Office) of complying with the minimum reserve requirements of the European Central Bank in respect of loans made from that Lending Office.

4.		The Additional Cost Rate for any Lender lending from a Lending Office in the United Kingdom will be calculated by the Administrative Agent as follows:

(a)

in relation to a sterling Eurocurrency Loan:


		AB + C(B - D) + E x 0.01
				per cent. per annum
		100 - (A+C)

(b)

in relation to a Eurocurrency Loan in any currency other than sterling:

Where:

is the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash ratio deposit with the Bank of England to comply with cash ratio requirements.

	B		is the percentage rate of interest (excluding the Applicable Margin and the Mandatory Cost and, if the Eurocurrency Loan is an unpaid sum, the additional rate of interest specified in paragraph (b) Section 2.7 (Default Rate)) payable for the relevant Interest Period on the Eurocurrency Loan.

	C		is the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.

	D		is the percentage rate per annum payable by the Bank of England to the Administrative Agent on interest bearing Special Deposits.

	E		is designed to compensate Lenders for amounts payable under the Fees Rules and is calculated by the Administrative Agent as being the average of the most recent rates of charge supplied by the Reference Banks to the Administrative Agent pursuant to paragraph 7 below and expressed in pounds per £1,000,000.

For the purposes of this Exhibit:

	(a)		“Eligible Liabilities” and “Special Deposits” have the meanings given to them from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of England;

	(b)		“FSA” means Financial Services Authority;

	(c)		“Fees Rules” means the rules on periodic fees contained in the FSA Supervision Manual or such other law or regulation as may be in force from time to time in respect of the payment of fees for the acceptance of deposits;

	(d)		“Fee Tariffs” means the fee tariffs specified in the Fees Rules under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fees Rules but taking into account any applicable discount rate);

	(e)		“Participating Member State” means any member state of the European Communities that adopts or has adopted the Euro as its lawful currency in accordance with legislation of the European Community relating to Economic and Monetary Union;

	(f)		“Reference Banks” means, in relation to LIBOR and Mandatory Cost, Citibank, N.A., SunTrust Bank or such other banks as may be appointed by the Administrative Agent in consultation with the Company; and

	(g)		“Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Rules.

In application of the above formula, A, B, C and D will be included in the formula as percentages (i.e. 5 per cent. will be included in the formula as 5 and not as 0.05). A

-2-

negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places.

If requested by the Administrative Agent, each Reference Bank shall, as soon as practicable after publication by the Financial Services Authority, supply to the Administrative Agent, the rate of charge payable by that Reference Bank to the Financial Services Authority pursuant to the Fees Rules in respect of the relevant financial year of the Financial Services Authority (calculated for this purpose by that Reference Bank as being the average of the Fee Tariffs applicable to that Reference Bank for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of that Reference Bank.

Each Lender shall supply any information required by the Administrative Agent for the purpose of calculating its Additional Cost Rate. In particular, but without limitation, each Lender shall supply the following information on or prior to the date on which it becomes a Lender:

	(a)		the jurisdiction of its Lending Office; and

	(b)		any other information that the Administrative Agent may reasonably require for such purpose.

Each Lender shall promptly notify the Administrative Agent of any change to the information provided by it pursuant to this paragraph.

The percentages of each Lender for the purpose of A and C above and the rates of charge of each Reference Bank for the purpose of E above shall be determined by the Administrative Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless a Lender notifies the Administrative Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as those of a typical bank from its jurisdiction of incorporation with a Lending Office in the same jurisdiction as its Lending Office.

10.

The Administrative Agent shall have no liability to any person if such determination results in an Additional Cost Rate which over or under compensates any Lender and shall be entitled to assume that the information provided by any Lender or Reference Bank pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects.

11.

The Administrative Agent shall distribute the additional amounts received as a result of the Mandatory Cost to the Lenders on the basis of the Additional Cost Rate for each Lender based on the information provided by each Lender and each Reference Bank pursuant to paragraphs 3, 7 and 8 above.

-3-

12.

Any determination by the Administrative Agent pursuant to this Exhibit in relation to a formula, the Mandatory Cost, an Additional Cost Rate or any amount payable to a Lender shall, in the absence of manifest error, be conclusive and binding on all parties.

13.

The Administrative Agent may from time to time, after consultation with the Company and the Lenders, determine and notify to all parties any amendments which are required to be made to this Exhibit in order to comply with any change in law, regulation or any requirements from time to time imposed by the Bank of England, the Financial Services Authority or the European Central Bank (or, in any case, any other authority which replaces all or any of its functions) and any such determination shall, in the absence of manifest error, be conclusive and binding on all parties.

FORM OF COMPANY GUARANTY

THIS GUARANTY AGREEMENT (this “Guaranty”), dated as of [date] is made by Noble Corporation, a Cayman Islands exempted company limited by shares (the “Company” or the “Guarantor”), in favor of (i) the Lenders (as defined in the Credit Agreement) (as hereinafter defined), (ii) Citibank, N.A., in its capacity as Administrative Agent (as defined in the Credit Agreement), (iii) Citibank, N.A., in its capacity as the Swingline Lender (as defined in the Credit Agreement), (iv) Other Agents (as defined in the Credit Agreement) and (v) the Issuing Banks (as defined in the Credit Agreement) (the Lenders, the Administrative Agent, the Other Agents, the Swingline Lender and the Issuing Banks are each individually referred to herein as a “Guaranteed Party”, and collectively, as the “Guaranteed Parties”);

WITNESSETH:

WHEREAS, the Company, the Lenders, the Administrative Agent, the Swingline Lender and the Issuing Banks are parties to a certain Revolving Credit Agreement dated as of March 15, 2007 (as the same may hereafter be amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; terms defined therein and not otherwise defined herein being used herein as therein defined);

WHEREAS, the Company has designated [DESIGNATED BORROWER] as the Designated Borrower under Section 2.18 of the Credit Agreement;

WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding capital stock or other equity interests of the Designated Borrower;

WHEREAS, it is a requirement under Section 2.18 of the Credit Agreement, as a condition to extending Loans and Letters of Credit to the Designated Borrower, that the Guarantor execute and deliver this Guaranty, and the Guarantor desires to execute and deliver this Guaranty to satisfy such requirement;

SECTION 1. Guaranty. The Guarantor hereby, irrevocably and unconditionally, guarantees the punctual payment when due, in lawful money of the United States of America or in another currency as provided for in Section 3.2(a) of the Credit Agreement (the “Obligation Currency”), whether at stated maturity, by acceleration or otherwise, of the Loans, L/C Obligations, and all other Obligations owing by the Designated Borrower to the Lenders, the Administrative Agent, the Swingline Lender, the Issuing Banks and Other Agents, or any of them, under the Credit Agreement, the Notes, and the other Credit

Documents, including all renewals, extensions, modifications and refinancings thereof, now or hereafter owing, whether for principal, interest, fees, expenses, indemnities, reimbursement obligations or otherwise, and any and all reasonable out-of-pocket expenses (including reasonable attorneys’ fees and expenses) incurred by the Lenders or the Administrative Agent in enforcing any rights under this Guaranty (collectively, the “Guaranteed Obligations”), including without limitation, all interest which, but for the filing of a petition in bankruptcy, would accrue on any principal portion of the Guaranteed Obligations. Any and all payments by the Guarantor hereunder shall be made in the Obligation Currency free and clear of and without deduction for any set-off, counterclaim, or withholding so that, in each case, each Guaranteed Party will receive, after giving effect to any Indemnified Taxes (as such term is defined in the Credit Agreement), the full amount, in the Obligation Currency, that it would otherwise be entitled to receive with respect to the Guaranteed Obligations (but without duplication of amounts for Indemnified Taxes already included in the Guaranteed Obligations). The Guarantor acknowledges and agrees that this is a guarantee of payment when due, and not of collection, and that this Guaranty may be enforced up to the full amount of the Guaranteed Obligations without proceeding against the Designated Borrower, against any security for the Guaranteed Obligations, against any other Person or under any other guaranty covering any portion of the Guaranteed Obligations.

-2-

(e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to the Guarantor, the Designated Borrower or any other Person, or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding;

(g) any application of sums paid by the Designated Borrower or any other Person with respect to the liabilities of the Designated Borrower to the Guaranteed Parties, regardless of what liabilities of the Designated Borrower remain unpaid;

(h) any act or failure to act by any Guaranteed Party which may adversely affect the Guarantor’s subrogation rights, if any, against the Designated Borrower to recover payments made under this Guaranty; and

(i) any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b) any settlement or compromise of any such claim effected by the Guaranteed Party with any such claimant (including, without limitation, the Designated Borrower or a trustee in bankruptcy for the Designated Borrower), then and in such event the Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Credit Agreement, the other Credit Documents, or any other instrument evidencing any liability of the Designated Borrower, and the Guarantor shall be and remain liable to the Guaranteed Party for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Guaranteed Party.

SECTION 3. Waiver. The Guarantor hereby waives notice of acceptance of this Guaranty, notice of any liability to which it may apply, and further waive presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by the Guaranteed Parties against, and any other notice to, the Designated Borrower or any other party liable with respect to the Guaranteed Obligations (including, without limitation, any other Person executing a guaranty of the obligations of the Designated Borrower).

-3-

SECTION 4. Subrogation. The Guarantor will not exercise any rights against the Designated Borrower which it may acquire by way of subrogation or contribution, by any payment made hereunder or otherwise, until all the Guaranteed Obligations shall have been irrevocably paid in full and the Credit Agreement and all Letters of Credit shall have been irrevocably terminated. If any amount shall be paid to the Guarantor on account of such subrogation or contribution rights at any time when all the Guaranteed Obligations shall not have been paid in full or the Credit Agreement or any Letter of Credit shall not have been irrevocably terminated, such amount shall be held in trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Credit Agreement. If (i) Guarantor shall make payment to the Guaranteed Parties of all or any part of the Guaranteed Obligations and (ii) all the Guaranteed Obligations shall be irrevocably paid in full and the Credit Agreement and all Letters of Credit shall have been irrevocably terminated, the Guaranteed Parties will, at Guarantor’s request, execute and deliver to Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to Guarantor of an interest in the Guaranteed Obligations resulting from such payment by Guarantor.

-4-

SECTION 9. Right of Set Off. In addition to and not in limitation of all rights of offset that the Administrative Agent or other Guaranteed Party may have under applicable law, the Administrative Agent or other Guaranteed Parties shall, upon the occurrence of any Event of Default and whether or not the Administrative Agent or other Guaranteed Party has made any demand or the Guaranteed Obligations are matured, have the right to appropriate and apply to the payment of the Guaranteed Obligations, all deposits of the Guarantor (general or special, time or demand, provisional or final) then or thereafter held by and other indebtedness or property then or thereafter owing by the Administrative Agent or other Guaranteed Party to the Guarantor, whether or not related to this Guaranty or any transaction hereunder.

SECTION 11. Governing Law; Appointment Of Agent For Service Of Process; Submission To Jurisdiction; Waiver of Jury Trial.

THE GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS IN RESPECT OF THIS GUARANTY OR ANY DOCUMENT RELATED THERETO. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE GUARANTOR IN ANY OTHER JURISDICTION.

SECTION 12. [Reserved].

payable under this Guaranty or the Credit Agreement. If for the purpose of obtaining or enforcing judgment against the Guarantor in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made in accordance with Section 10.18 of the Credit Agreement.

SECTION 14. Automatic Acceleration in Certain Events. Upon the occurrence of an Event of Default specified in Section 7.1(f) or (g) of the Credit Agreement, all Guaranteed Obligations shall automatically become immediately due and payable by the Guarantor without notice or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless of whether payment of the Guaranteed Obligations by the Designated Borrower has then been accelerated. In addition, if any event of the types described in Section 7.1(f) or (g) of the Credit Agreement should occur with respect to the Guarantor, then the Guaranteed Obligations shall automatically become immediately due and payable by the Guarantor, without notice or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless of whether payment of the Guaranteed Obligations by the Designated Borrower has then been accelerated.

SECTION 15. Maximum Obligations. (a) It is the intent of the Guarantor and the Guaranteed Parties that the Guarantor’s maximum obligations hereunder shall be in, but not in excess of:

-7-

Guarantor under such law, statute or regulation including, without limitation, any state fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding.

(b) To the end set forth in Section 15(a), but only to the extent that the Guaranteed Obligations would otherwise be subject to avoidance under the Avoidance Provisions if the Guarantor is not deemed to have received valuable consideration, fair value or reasonably equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would render the Guarantor insolvent, or leave the Guarantor with an unreasonably small capital to conduct its business, or cause the Guarantor to have incurred debts (or to have intended to have incurred debts) beyond its ability to pay such debts as they mature, in each case as of the time any of the Guaranteed Obligations are deemed to have been incurred under the Avoidance Provisions and after giving effect to rights of contribution, indemnity and subrogation as between the Guarantor and the Designated Borrower, the maximum Guaranteed Obligations for which the Guarantor shall be liable hereunder shall be reduced to that amount which, after giving effect thereto, would not cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties), as so reduced, to be subject to avoidance under the Avoidance Provisions. This Section 15(b) is intended solely to preserve the rights of the Guaranteed Parties hereunder to the maximum extent that would not cause the Guaranteed Obligations of the Guarantor to be subject to avoidance under the Avoidance Provisions, and neither the Guarantor nor any other Person shall have any right or claim under this Section 15 as against the Guaranteed Parties that would not otherwise be available to such Person under the Avoidance Provisions.

SECTION 16. Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as the Guarantor may have under applicable law (but subject to Section 4 hereof), the Designated Borrower agrees that (i) in the event a payment shall be made on behalf of the Designated Borrower by the Guarantor hereunder, the Designated Borrower shall indemnify the Guarantor for the full amount of such payment and the Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment, and (ii) in the event any assets of the Guarantor shall be sold to satisfy a claim of any Guaranteed Party hereunder, the Designated Borrower shall indemnify the Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

SECTION 17. Information. The Guarantor assumes all responsibility for being and keeping itself informed of the Designated Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that the Guarantor assumes and incurs hereunder, and agrees that none of the Guaranteed Parties will have any duty to advise any of the Guarantor of information known to it or any of them regarding such circumstances or risks.

SECTION 20. Counterparts. This Guaranty and any amendments, waivers, consents or supplements may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument.

SUBSIDIARY GUARANTY AGREEMENT

THIS SUBSIDIARY GUARANTY AGREEMENT (this “Guaranty”), dated as of , , made by each of the undersigned Subsidiaries of Noble Corporation, a Cayman Islands exempted company limited by shares (the “Company”; each undersigned Subsidiary of the Company being herein referred to individually as a “Guarantor” and collectively as the “Guarantors”), in favor of (i) the banks and other financial institutions that are parties to the Credit Agreement (as hereinafter defined) and each assignee thereof becoming a “Lender” as provided therein (the “Lenders”), (ii) Citibank, N.A., in its capacity as administrative agent (the “Administrative Agent”) under the terms of the Credit Agreement and (iii) Other Agents and the Issuing Banks (as such terms are defined in the Credit Agreement) under the terms of the Credit Agreement (the Lenders, the Administrative Agent, the Other Agents, and the Issuing Banks being collectively referred to herein as the “Guaranteed Parties”);

WITNESSETH:

WHEREAS, the Company, the Lenders and the Administrative Agent have entered into a certain Revolving Credit Agreement dated as of March 15, 2007 (as the same may hereafter be amended, restated, supplemented or otherwise modified from time to time, and including all schedules, riders, and supplements thereto, the “Credit Agreement”; terms defined therein and not otherwise defined herein being used herein as therein defined);

WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding capital stock or other equity interests of each Guarantor;

WHEREAS, it is a requirement under Section 6.11(k) of the Credit Agreement that each Guarantor execute and deliver this Guaranty, and each Guarantor desires to execute and deliver this Guaranty to satisfy such requirement; and

WHEREAS, this Guaranty and the obligation of each Guarantor shall remain in full force and effect until termination of this Guaranty as provided in Section 23 below or as otherwise provided in Section 10(i) below;

NOW, THEREFORE, in consideration of the premises and in order to satisfy the requirements of the Credit Agreement, and for Ten Dollars ($10.00) and other good and valuable consideration, each Guarantor hereby jointly and severally agrees as follows:

SECTION 1. Guaranty. Subject to Section 23 below, each Guarantor hereby jointly and severally, irrevocably and unconditionally, guarantees the punctual payment when due, in lawful money of the United States of America or in another currency as provided for in Section 3.2(a) of the Credit Agreement (the “Obligation Currency”), whether at stated

maturity, by acceleration or otherwise, of the Loans, L/C Obligations, and all other Obligations owing by the Company to the Lenders, the Administrative Agent, the Swingline Leader, the Issuing Banks and Other Agents, or any of them, under the Credit Agreement, the Notes, and the other Credit Documents, including all renewals, extensions, modifications and refinancings thereof, now or hereafter owing, whether for principal, interest, fees, expenses or otherwise, and any and all reasonable out-of-pocket expenses (including reasonable attorneys’ fees and expenses) incurred by the Lenders or the Administrative Agent in enforcing any rights under this Guaranty (collectively, the “Guaranteed Obligations”), including without limitation, all interest which, but for the filing of a petition in bankruptcy, would accrue on any principal portion of the Guaranteed Obligations. Any and all payments by each Guarantor hereunder shall be made in the Obligation Currency free and clear of and without deduction for any set-off, counterclaim, or withholding so that, in each case, each Guaranteed Party will receive, after giving effect to any Indemnified Taxes (as such term is defined in the Credit Agreement), the full amount, in the Obligation Currency, that it would otherwise be entitled to receive with respect to the Guaranteed Obligations (but without duplication of amounts for Indemnified Taxes already included in the Guaranteed Obligations). Each Guarantor acknowledges and agrees that this is a guarantee of payment when due, and not of collection, and that this Guaranty may be enforced up to the full amount of the Guaranteed Obligations without proceeding against the Company, against any security for the Guaranteed Obligations, against any other Guarantor or under any other guaranty covering any portion of the Guaranteed Obligations.

SECTION 2. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Guaranteed Party with respect thereto. Subject to Section 23 below, the liability of each Guarantor under this Guaranty shall be absolute and unconditional in accordance with its terms and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever, including, without limitation, the following (whether or not such Guarantor consents thereto or has notice thereof):

(c) any furnishing to the Guaranteed Parties of any additional security for the Guaranteed Obligations, or any sale, exchange, release or surrender of, or realization on, any security for the Guaranteed Obligations;

-2-

(e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to any Guarantor or the Company, or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding;

(h) any act or failure to act by any Guaranteed Party which may adversely affect a Guarantor’s subrogation rights, if any, against the Company to recover payments made under this Guaranty; and

(i) any other circumstance which might otherwise constitute a defense available to, or a discharge of, any Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b) any settlement or compromise of any such claim effected by the Guaranteed Party with any such claimant (including the Company or a trustee in bankruptcy for the Company), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Credit Agreement, the other Credit Documents, or any other instrument evidencing any liability of the Company, and each Guarantor shall be and remain liable to the Guaranteed Party for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Guaranteed Party.

SECTION 3. Waiver. Each Guarantor hereby waives notice of acceptance of this Guaranty, notice of any liability to which it may apply, and further waive presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by the Guaranteed Parties against, and any other notice to, the Company or any other party liable with respect to the Guaranteed Obligations (including the Guarantors or any other Person executing a guaranty of the obligations of the Company).

-3-

SECTION 4. Subrogation. No Guarantor will exercise any rights against the Company which it may acquire by way of subrogation or contribution, by any payment made hereunder or otherwise, until all the Guaranteed Obligations shall have been irrevocably paid in full and the Credit Agreement and all Letters of Credit shall have been irrevocably terminated. If any amount shall be paid to a Guarantor on account of such subrogation or contribution rights at any time when all the Guaranteed Obligations shall not have been paid in full, or the Credit Agreement or any Letter of Credit shall not have been irrevocably terminated, such amount shall be held in trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Credit Agreement. If (i) a Guarantor shall make payment to the Guaranteed Parties of all or any part of the Guaranteed Obligations and (ii) all the Guaranteed Obligations shall be irrevocably paid in full and the Credit Agreement and all Letters of Credit irrevocably terminated, the Guaranteed Parties will, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by such Guarantor.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guaranty nor consent to any departure by a Guarantor therefrom shall in any event be effective unless the same shall be in writing executed by the Administrative Agent and the Lenders.

SECTION 7. Notices. All notices and other communications provided for hereunder shall be given in the manner specified in the Credit Agreement (i) in the case of the Administrative Agent, at the address specified for the Administrative Agent in the Credit Agreement, and (ii) in the case of the Guarantors, at the respective addresses specified for such Guarantors in this Guaranty.

SECTION 8. No Waiver; Remedies. No failure on the part of the Administrative Agent or other Guaranteed Parties to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in any similar or other circumstances or constitute a waiver of the rights of the Administrative Agent or other Guaranteed Parties to any other or further action in any circumstances without notice or demand. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

-4-

SECTION 9. Right Of Set Off. In addition to and not in limitation of all rights of offset that the Administrative Agent or other Guaranteed Parties may have under applicable law, the Administrative Agent or other Guaranteed Parties shall, upon the occurrence of any Event of Default and whether or not the Administrative Agent or other Guaranteed Parties have made any demand or the Guaranteed Obligations are matured, have the right to appropriate and apply to the payment of the Guaranteed Obligations, all deposits of any Guarantor (general or special, time or demand, provisional or final) then or thereafter held by and other indebtedness or property then or thereafter owing by the Administrative Agent or other Guaranteed Parties to any Guarantor, whether or not related to this Guaranty or any transaction hereunder.

SECTION 10. Continuing Guaranty; Transfer Of Obligations. This Guaranty is a continuing guaranty and shall (i) remain in full force and effect, subject to Section 23 below, until payment in full of the Guaranteed Obligations and all other amounts payable under this Guaranty, irrevocable termination of all Letters of Credit and the termination of the Credit Agreement, (ii) be binding upon each Guarantor, its successors and assigns, and (iii) inure to the benefit of and be enforceable by the Administrative Agent, for the benefit of the Guaranteed Parties.

SECTION 11. Governing Law; Appointment Of Agent For Service Of Process; Submission To Jurisdiction; Waiver of Jury Trial.

-5-

EXTENT PERMITTED BY APPLICABLE LAW, AFFECT IN ANY WAY THE SERVICE OF SUCH PROCESS. IF FOR ANY REASON SERVICE OF PROCESS CANNOT PROMPTLY BE MADE ON EITHER SUCH LOCAL AGENT, EACH GUARANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS 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 THE COMPANY AT ITS SAID ADDRESS, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS IN RESPECT OF THIS GUARANTY OR ANY DOCUMENT RELATED THERETO. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY GUARANTOR IN ANY OTHER JURISDICTION.

(c) TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN CONNECTION WITH THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT OR ANY MATTER ARISING IN CONNECTION HEREUNDER OR THEREUNDER.

(e) EACH OF THE GUARANTORS AND THE GUARANTEED PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THIS SECTION 11 OR OTHERWISE RELATING TO THE CREDIT DOCUMENTS ANY PUNITIVE DAMAGES.

SECTION 12. [INTENTIONALLY OMITTED]

SECTION 13. Judgment Currency. Each Guarantor’s obligation hereunder to make payments in the Obligation Currency shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by the Guaranteed Parties of the full amount of the Obligation Currency expressed to be payable under this Guaranty or the Credit Agreement. If for the purpose of obtaining or enforcing judgment against any Guarantor in any court or in any jurisdiction, it

-6-

becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made in accordance with Section 10.18 of the Credit Agreement.

SECTION 14. Automatic Acceleration in Certain Events. Upon the occurrence of an Event of Default specified in Section 7.1(f) or (g) of the Credit Agreement, all Guaranteed Obligations shall automatically become immediately due and payable by the Guarantors, without notice or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless of whether payment of the Guaranteed Obligations by the Company has then been accelerated. In addition, if any event of the types described in Section 7.1(f) or (g) of the Credit Agreement should occur with respect to any Guarantor that is a Significant Subsidiary, then the Guaranteed Obligations shall automatically become immediately due and payable by such Guarantor, without notice or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless of whether payment of the Guaranteed Obligations by the Company has then been accelerated.

SECTION 15. Maximum Obligations. (a) It is the intent of each Guarantor and the Guaranteed Parties that each Guarantor’s maximum obligations hereunder shall be in, but not in excess of:

(i) in a case or proceeding commenced by or against such Guarantor under the Bankruptcy Code on or within one year from the date on which any of the Guaranteed Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against such Guarantor under (A) Section 548 of the Bankruptcy Code or (B) any state fraudulent transfer or fraudulent conveyance act or statute applied in such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or

(ii) in a case or proceeding commenced by or against such Guarantor under the Bankruptcy Code subsequent to one year from the date on which any of the Guaranteed Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against such Guarantor under any state fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or

(iii) in a case or proceeding commenced by or against such Guarantor under any law, statute or regulation other than the Bankruptcy Code (including, without limitation, any other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt, dissolution, liquidation or similar debtor relief laws), the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) to be avoidable or unenforceable against such Guarantor under such law, statute or regulation including, without limitation, any state

-7-

fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding.

(The substantive laws under which the possible avoidance or unenforceability of the Guaranteed Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) shall be determined in any such case or proceeding shall hereinafter be referred to as the “Avoidance Provisions”).

(b) To the end set forth in Section 15(a), but only to the extent that the Guaranteed Obligations would otherwise be subject to avoidance under the Avoidance Provisions if such Guarantor is not deemed to have received valuable consideration, fair value or reasonably equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would render such Guarantor insolvent, or leave such Guarantor with an unreasonably small capital to conduct its business, or cause such Guarantor to have incurred debts (or to have intended to have incurred debts) beyond its ability to pay such debts as they mature, in each case as of the time any of the Guaranteed Obligations are deemed to have been incurred under the Avoidance Provisions and after giving effect to rights of contribution, indemnity and subrogation as among Guarantors and the Company, the maximum Guaranteed Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, after giving effect thereto, would not cause the Guaranteed Obligations (or any other obligations of such Guarantor to the Guaranteed Parties), as so reduced, to be subject to avoidance under the Avoidance Provisions. This Section 15(b) is intended solely to preserve the rights of the Guaranteed Parties hereunder to the maximum extent that would not cause the Guaranteed Obligations of any Guarantor to be subject to avoidance under the Avoidance Provisions, and neither such Guarantor nor any other Person shall have any right or claim under this Section 15 as against the Guaranteed Parties that would not otherwise be available to such Person under the Avoidance Provisions.

SECTION 16. Indemnity, Contribution, and Subrogation.

(a) In addition to all such rights of indemnity and subrogation as each Guarantor may have under applicable law (but subject to Section 4 hereof), the Company agrees that (i) in the event a payment shall be made on behalf of the Company by any Guarantor hereunder, the Company shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment, and (ii) in the event any assets of any Guarantor shall be sold to satisfy a claim of any Guaranteed Party hereunder, the Company shall indemnify such Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

(b) Each Guarantor (a “Contributing Guarantor”) agrees (subject to Section 4 hereof), that, in the event a payment shall be made by any other Guarantor hereunder, or assets of any other Guarantor shall be sold to satisfy a claim of any Guaranteed Party hereunder, and such other Guarantor (the “Claiming Guarantor”) shall not have been fully indemnified by the Company as provided in paragraph (a) above, each Contributing Guarantor shall indemnify each

-8-

Claiming Guarantor in an amount equal to the amount of such payment or the greater of the book value or the fair market value of such assets, as the case may be, in each case multiplied by a fraction of which the numerator shall be the net worth of such Contributing Guarantor on the date hereof and the denominator shall be the aggregate net worth of the Company and all of the Guarantors on the date hereof (or, in the case of any Guarantor becoming a party hereto pursuant to Section 22, the date of the Supplement hereto executed and delivered by such Guarantor). Any Contributing Guarantor making any payment to a Claiming Guarantor pursuant to this paragraph (b) shall be subrogated to the rights of such Claiming Guarantor under paragraph (a) above to the extent of such payment. As used herein, the term “net worth” shall mean, as at any date of determination, the consolidated shareholders’ equity of the Company and the Guarantors, as determined in each case on a consolidated basis in accordance with GAAP.

SECTION 17. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the Company’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Guaranteed Parties will have any duty to advise any of the Guarantors of information known to it or any of them regarding such circumstances or risks.

SECTION 18. Representations and Warranties. Each Guarantor represents and warrants as to itself that all representations and warranties relating to it contained in Article 5 of the Credit Agreement are true and correct.

SECTION 19. Survival of Agreement. All agreements, representations and warranties made herein shall survive the execution and delivery of this Guaranty, the Credit Agreement, the making of the Loans, and the execution and delivery of the Notes and the other Credit Documents and the issuance of Letters of Credit.

SECTION 21. Currency of Payment. All payments to be made by each Guarantor hereunder shall be made in the applicable currency as provided in Section 10.18 of the Credit Agreement and, in the case of any required conversion of any currency, shall be determined, and the related amounts calculated, in the manner provided in Section 10.18 of the Credit Agreement.

SECTION 22. Additional Guarantors. Upon execution and delivery by any Subsidiary of the Company of an instrument in the form of Annex 1, such Subsidiary shall become a Guarantor hereunder with the same force and effect as if originally named a Guarantor herein (each an “Additional Guarantor”). The execution and delivery of any such instrument shall not require the consent of any Guarantor hereunder. The rights and obligations of each

-9-

Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any Additional Guarantor as a party to this Guaranty.

SECTION 23. Termination of Guaranty. In addition to termination upon payment in full of all of the Guaranteed Obligations (subject to the last sentence of Section 2 hereof), all obligations of each Guarantor to the Guaranteed Parties hereunder shall terminate upon the delivery by the Company to the Administrative Agent of a certificate stating that (i) the aggregate principal amount of Indebtedness of all Subsidiaries outstanding pursuant to Section 6.11(j) and (k) of the Credit Agreement is equal to or less than the Subsidiary Debt Basket Amount, and (ii) no Default or Event of Default has occurred and is continuing. Upon compliance with the foregoing, the Administrative Agent and the Lender shall provide written confirmation of such termination as may be reasonably requested by such Guarantor.

-10-

IN WITNESS WHEREOF, each Guarantor and the Administrative Agent have caused this Guaranty to be duly executed and delivered by their respective duly authorized officers as of the date first above written.
