Unless the Administrative Agent shall have been notified by any Lender prior to the date of any such Borrowing that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the US Borrower or the UK Borrower, as the case may be, a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available same to the US Borrower or the UK Borrower, as the case may be, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor the Administrative Agent shall promptly notify the US Borrower or the UK Borrower, as the case may be, and the US Borrower or the UK Borrower, as the case may be, shall immediately pay such corresponding amount to the Administrative Agent. The Administrative Agent shall also be entitled to recover from such Lender or the US Borrower or the UK Borrower, as the case may be, interest on

such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the US Borrower or the UK Borrower, as the case may be, to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if paid by such Lender, the Federal Funds Effective Rate or (ii) if paid by the US Borrower or the UK Borrower, as the case may be, the then-applicable rate of interest, calculated in accordance with Section 2.8, for the respective Loans.

(c) Nothing in this Section 2.4 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the US Borrower or the UK Borrower, as the case may be, may have against any Lender as a result of any default by such Lender hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder).

It is understood and agreed that, in the event that the Acquisition is not consummated on July 31, 2004 and the Loans are prepaid, interest on each Loan made on the Funding Date shall accrue from and including the Funding Date to but excluding the date of the repayment thereof in accordance with this Agreement and such interest shall be payable on the date of such prepayment.

(b) if any Interest Period relating to a Borrowing of Eurodollar Term Loans, Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans begins on the last Business Day of a calendar month or begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period;

(c) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided, that if any Interest Period in respect of a Eurodollar Term Loan, Eurodollar Revolving Credit Loan or Eurodollar Extended Revolving Credit Loan would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day; and

Increased Costs, Illegality, etc. (a) In the event that (x) in the case of clause (i) below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender shall have reasonably determined (which determination shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto):

(i) on any date for determining the Eurodollar Rate for any Interest Period that (x) deposits in the principal amounts of the Loans comprising such Eurodollar Borrowing and in the currency in which such Loan is to be denominated are not generally available in the relevant market or (y) by reason of any changes arising on or after the Funding Date affecting the interbank Eurodollar market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate; or

(ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to any Eurodollar Loans (other than any such increase or reduction attributable to taxes) because of (x) any change since the Funding Date in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or order), such

as, for example, without limitation, a change in official reserve requirements, and/or (y) other circumstances affecting the interbank Eurodollar market or the position of such Lender in such market; or

(iii) at any time, that the making or continuance of any Eurodollar Loan has become unlawful by compliance by such Lender in good faith with any law, governmental rule, regulation, guideline or order (or would conflict with any such governmental rule, regulation, guideline or order not having the force of law even though the failure to comply therewith would not be unlawful), or has become impracticable as a result of a contingency occurring after the Funding Date that materially and adversely affects the interbank Eurodollar market;

then, and in any such event, such Lender (or the Administrative Agent, in the case of clause (i) above) shall within a reasonable time thereafter give notice (if by telephone, confirmed in writing) to the US Borrower (on its own behalf and on behalf of the UK Borrower) and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Eurodollar Term Loans, Eurodollar Revolving Credit Loans and Eurodollar Extended Revolving Credit Loans shall no longer be available until such time as the Administrative Agent notifies the US Borrower (on its own behalf and on behalf of the UK Borrower) and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist (which notice the Administrative Agent agrees to give at such time when such circumstances no longer exist), and any Notice of Borrowing or Notice of Conversion given by the US Borrower or the UK Borrower with respect to Eurodollar Term Loans, Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans that have not yet been incurred shall be deemed rescinded by the US Borrower or the UK Borrower, (y) in the case of clause (ii) above, the US Borrower or the UK Borrower, as the case may be, shall pay to such Lender, promptly after receipt of written demand therefor such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its reasonable discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder (it being agreed that a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the US Borrower or the UK Borrower, as the case may be, by such Lender shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the US Borrower or the UK Borrower, as the case may be, shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within the time period required by law.

(b) At any time that any Eurodollar Loan is affected by the circumstances described in Section 2.10(a)(ii) or (iii), the US Borrower or the UK Borrower, as the case may be, may (and in the case of a Eurodollar Loan affected pursuant to Section 2.10(a)(iii) shall) either (x) if the affected Eurodollar Loan is then being made pursuant to a Borrowing, cancel said Borrowing by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the US Borrower or the UK Borrower, as the case may be, was notified by a Lender pursuant to Section

2.10(a)(ii) or (iii) or (y) if the affected Eurodollar Loan is a Tranche E Term Loan, a Tranche H Term Loan, a Dollar Revolving Credit Loan or a Dollar Extended Revolving Credit Loan and is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such Eurodollar Revolving Credit Loan, Eurodollar Extended Revolving Credit Loan and Eurodollar Term Loan into an ABR Loan; provided, that if more than one Lender is affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b).

(c) If, after the Funding Date, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, the National Association of Insurance Commissioners, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by a Lender or its parent with any request or directive made or adopted after the Funding Date regarding capital adequacy (whether or not having the force of law) of any such authority, association, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s or its parent’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy), then from time to time, promptly after demand by such Lender (with a copy to the Administrative Agent), the US Borrower or the UK Borrower, as the case may be, shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent for such reduction, it being understood and agreed, however, that a Lender shall not be entitled to such compensation as a result of such Lender’s compliance with, or pursuant to any request or directive to comply with, any such law, rule or regulation as in effect on the Funding Date. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the US Borrower (on its own behalf and on behalf of the UK Borrower), which notice shall set forth in reasonable detail the basis of the calculation of such additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish any of the US Borrower’s or the UK Borrower’s, as the case may be, obligations to pay additional amounts pursuant to this Section 2.10(c) upon receipt of such notice.

(d) Notwithstanding the foregoing, in the case of Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans affected by the circumstances described in Section 2.10(a)(i), as promptly as practicable but in no event later than three Business Days after the giving of the required notice by the Administrative Agent with respect to such circumstances, the Administrative Agent (in consultation with the Lenders) shall negotiate with the US Borrower in good faith in order to ascertain whether a substitute interest rate (a “Substitute Rate”) may be agreed upon for the maintaining of existing Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans. If a Substitute Rate is agreed upon by the US Borrower and all the Lenders, such Substitute Rate shall apply. If a Substitute Rate is not so agreed upon by the US Borrower and all the Lenders within such time,

each Lender’s Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans, as applicable, shall thereafter bear interest at a rate equal to the sum of (i) the rate certified by such Lender to be its costs of funds (from such sources as it may reasonably select out of those sources then available to it) for such Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans, as applicable, plus (ii) the Applicable Eurodollar Margin plus (iii), in the case of Foreign Currency Loans denominated in Sterling only, any Additional Cost incurred by such Lender in respect of such Sterling Foreign Currency Loans from time to time.

2.11. Compensation. If (a) any payment of principal of any Eurodollar Term Loan, Eurodollar Revolving Credit Loan or Eurodollar Extended Revolving Credit Loan is made by the US Borrower or the UK Borrower, as the case may be, to or for the account of a Lender other than on the last day of the Interest Period for such Eurodollar Loan as a result of a payment or conversion pursuant to Section 2.5, 2.6, 2.10, 5.1, 5.2 or 14.7, as a result of acceleration of the maturity of the Loans pursuant to Section 11 or for any other reason, (b) any Borrowing of Eurodollar Term Loans, Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans is not made as a result of a withdrawn Notice of Borrowing, (c) any ABR Loan is not converted into a Eurodollar Term Loan, Eurodollar Revolving Credit Loan or Eurodollar Extended Revolving Credit Loan as a result of a withdrawn Notice of Conversion or Continuation, (d) any Eurodollar Loan is not continued as a Eurodollar Term Loan, Eurodollar Revolving Credit Loan or Eurodollar Extended Revolving Credit Loan as a result of a withdrawn Notice of Conversion or Continuation or (e) any prepayment of principal of any Eurodollar Term Loan, Eurodollar Revolving Credit Loan or Eurodollar Extended Revolving Credit Loan is not made as a result of a withdrawn notice of prepayment pursuant to Section 5.1 or 5.2, the US Borrower or the UK Borrower, as the case may be, shall, after receipt of a written request by such Lender (which request shall set forth in reasonable detail the basis for requesting such amount), pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that such Lender may reasonably incur as a result of such payment, failure to convert, failure to continue or failure to prepay, including any loss, cost or expense (excluding loss of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Eurodollar Loan.

2.12. Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(b), 3.5 or 5.4 with respect to such Lender, it will, if requested by the US Borrower or the UK Borrower, as the case may be, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event; provided, that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 2.12 shall affect or postpone any of the obligations of the US Borrower or the UK Borrower, as the case may be, or the right of any Lender provided in Section 2.10, 3.5 or 5.4.

2.13. Notice of Certain Costs. Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 2.10, 2.11, 3.5 or 5.4 is given by any Lender more than 180 days after such Lender has knowledge (or should have had knowledge) of the occurrence of the event giving rise to the additional cost, reduction in amounts, loss, tax or other additional amounts described in such Sections, such Lender shall not be entitled to compensation under Section 2.10, 2.11, 3.5 or 5.4, as the case may be, for any such amounts incurred or accruing prior to the giving of such notice to the US Borrower or the UK Borrower, as the case may be.

2.14. Incremental Facilities. The US Borrower may by written notice to the Administrative Agent elect to request the establishment of one or more (x) new Tranche H Term Loan Commitments (the “New Tranche H Term Loan Commitments”) and/or new Tranche I Term Loans Commitments (the “New Tranche I Term Loan Commitments”) and/or (y) new Revolving Credit Commitments (the “New Revolving Credit Commitment”) and/or new Extended Revolving Credit Commitments (the “New Extended Revolving Loan Commitments” and, together with the New Tranche H Term Loan Commitments, the New Tranche I Term Loan Commitment and the New Revolving Credit Commitments, the “New Loan Commitments”), by an aggregate amount not less than $25,000,000 individually (or such lesser amount which shall be approved by the Administrative Agent or such lesser amount that shall constitute the difference between $250,000,000 and all such New Loan Commitments obtained prior to such date), and integral multiples of $5,000,000 in excess of that amount, and in any event, by an aggregate amount which, when taken together with the principal amount of any Permitted Additional Notes, shall not exceed $250,000,000 in the aggregate. Each such notice shall specify the date (each, an “Increased Amount Date”) on which the US Borrower proposes that the New Loan Commitments shall be effective, which shall be a date not less than 10 Business Days after the date on which such notice is delivered to the Administrative Agent; provided, that the US Borrower shall first offer the Lenders to provide all of the New Loan Commitments prior to offering any other Person that is an eligible assignee pursuant to Section 14.6(b); provided further, that any Lender offered or approached to provide all or a portion of the New Loan Commitments may elect or decline, in its sole discretion, to provide a New Loan Commitment. Such New Loan Commitments shall become effective, as of such Increased Amount Date; provided, that (1) no Default or Event of Default shall exist on such Increased Amount Date before or after giving effect to such New Loan Commitments, as applicable; (2) both before and after giving effect to the making of any Series of New Tranche H Term Loans, New Tranche I Term Loans, New Revolving Loans, or New Extended Revolving Loans, each of the conditions set forth in Section 7.1 and 7.2 shall be satisfied; (3) the US Borrower and its Subsidiaries shall be in pro forma compliance with each of the covenants set forth in Sections 10.9 and 10.10 as of the last day of the most recently ended fiscal quarter after giving effect to such New Loan Commitments and any investment to be consummated in connection therewith; (4) the New Loan Commitments shall be effected pursuant to one or more Joinder Agreements executed and delivered by the US Borrower and Administrative Agent, and each of which shall be recorded in the Register by the US Borrower and Administrative Agent, and shall be subject to the requirements set forth in Section 5.4(b); (5) the US Borrower shall make any payments required pursuant to Section 2.11 in connection with the New Loan Commitments, as applicable; and (6) the US Borrower

SECTION 3. Letters of Credit

(a) Subject to and upon the terms and conditions herein set forth, (i) the US Borrower or the UK Borrower, at any time and from time to time on or after the Funding Date and prior to the L/C Maturity Date, may request that the Letter of Credit Issuer issue for the account of the US Borrower or the UK Borrower, as the case may be, a standby letter of credit or letters of credit in Dollars (each a “Dollar Letter of Credit” and, collectively, the “Dollar Letters of Credit”) in such form as may be approved by the Letter of Credit Issuer in its reasonable discretion and (ii) the US Borrower or the UK Borrower, at any time and from time to time on or after the Funding Date and prior to the L/C Maturity Date, may request that the Letter of Credit Issuer issue for the account of the US Borrower or the UK Borrower, as the case may be, a standby letter of credit or letters of credit in a Foreign Currency (each a “Foreign Currency Letter of Credit” and, collectively, the “Foreign Currency Letters of Credit” and, together with the Dollar Letters of Credit, the “Letters of Credit”) in such form as may be approved by the Letter of Credit Issuer in its reasonable discretion. Notwithstanding anything contained herein to the contrary, it is acknowledged and agreed that, from and after the Restatement Date, (a) all Letter of Credit Exposure with respect to Converting Letters of Credit and any related Unpaid Drawings shall be deemed for all purposes hereunder to be issued under the Extended Revolving Credit Commitment, (b) there shall be an automatic adjustment to the participations held by each Lender thereunder pursuant to Section 3.3 so that the undivided participation and interest of the Lenders in each such Converting Letter of Credit and any related Unpaid Drawing is deemed to be made in respect of the Extended Revolving Credit Commitment as if such

Converting Letter of Credit were made on or after the Restatement Date and (c) all Letters of Credit issued after the Restatement Date shall be issued under the Extended Revolving Credit Commitment; provided, however, that if, the Extended Revolving Credit Exposure equals or exceeds the Total Extended Revolving Credit Commitment and all possible automatic refinancings of Extended Revolving Loans have occurred pursuant to Section 2.1(b)(i) or (ii), as applicable, then Letters of Credit may be issued under the Revolving Credit Commitment.

(b) Notwithstanding the foregoing, (i) no Letter of Credit shall be issued the Dollar Equivalent of the Stated Amount of which, when added to the Letter of Credit Outstanding at such time, would exceed the Letter of Credit Commitment then in effect; (ii) no Letter of Credit shall be issued the Dollar Equivalent of the Stated Amount of which would cause (A) the aggregate amount of the Lenders’ Revolving Credit Exposures at such time to exceed the Total Revolving Credit Commitment then in effect or (B) the aggregate amount of the Lenders’ Extended Revolving Credit Exposures at such time to exceed the Total Extended Revolving Credit Commitment then in effect; (iii) each Letter of Credit shall have an expiration date occurring no later than one year after the date of issuance thereof, unless otherwise agreed upon by the Administrative Agent and the Letter of Credit Issuer; provided, that any Letter of Credit may, upon request of the US Borrower or the UK Borrower, as the case may be, provide for the automatic renewal thereof for additional consecutive periods of one year or less (which in no event shall extend beyond the L/C Maturity Date), subject to any conditions specified in such Letter of Credit; and provided further, that in no event shall such expiration date occur later than the L/C Maturity Date; (iv) each Letter of Credit shall be denominated in Dollars or in a Foreign Currency; (v) no Letter of Credit shall be issued if it would be illegal under any applicable law for the beneficiary of the Letter of Credit to have a Letter of Credit issued in its favor; and (vi) no Letter of Credit shall be issued by the Letter of Credit Issuer after it has received a written notice from the US Borrower, the UK Borrower or any Lender stating that a Default or Event of Default has occurred and is continuing until such time as the Letter of Credit Issuer shall have received a written notice of (x) rescission of such notice from the party or parties originally delivering such notice or (y) the waiver of such Default or Event of Default in accordance with the provisions of Section 14.1.

(c) Upon at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent and the Letter of Credit Issuer (which notice the Administrative Agent shall promptly transmit to each of the Lenders), the US Borrower (on its own behalf and on behalf of the UK Borrower) shall have the right, on any day, permanently to terminate or reduce the Letter of Credit Commitment in whole or in part; provided, that, after giving effect to such termination or reduction, the Letter of Credit Outstanding shall not exceed the Letter of Credit Commitment.

3.2. Letter of Credit Requests. (a) Whenever the US Borrower or the UK Borrower desires that a Letter of Credit be issued for its account, it shall give the Administrative Agent and the Letter of Credit Issuer at least five (or such lesser number as may be agreed upon by the Administrative Agent and the Letter of Credit Issuer)

Business Days’ written notice thereof. Each notice shall be executed by the US Borrower or the UK Borrower, as the case may be, and shall be in the form of Exhibit N (each a “Letter of Credit Request”). The Administrative Agent shall promptly notify each Lender of such issuance.

(b) The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the US Borrower or the UK Borrower, as the case may be, that the Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.1(b).

3.3. Letter of Credit Participations. (a) Immediately upon the issuance by the Letter of Credit Issuer of any Letter of Credit, the Letter of Credit Issuer shall be deemed to have sold and transferred to each other Lender that has a Revolving Credit Commitment or an Extended Revolving Credit Commitment, as applicable (each such other Lender, in its capacity under this Section 3.3, an “L/C Participant”), and each such L/C Participant shall be deemed irrevocably and unconditionally to have purchased and received from the Letter of Credit Issuer, without recourse or warranty, an undivided interest and participation (each an “L/C Participation”), to the extent of such L/C Participant’s Revolving Credit Commitment Percentage or Revolving Credit Commitment Percentage, as applicable, in such Letter of Credit, each substitute letter of credit, each drawing made thereunder and the obligations of the US Borrower or the UK Borrower, as the case may be, under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto (although Letter of Credit Fees will be paid directly to the Administrative Agent for the ratable account of the L/C Participants as provided in Section 4.1(c) and the L/C Participants shall have no right to receive any portion of any Fronting Fees).

(b) In determining whether to pay under any Letter of Credit, the Letter of Credit Issuer shall have no obligation other than to confirm that any documents required to be delivered under such Letter of Credit have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by the Letter of Credit Issuer under or in connection with any Letter of Credit issued by it, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for the Letter of Credit Issuer any resulting liability.

(c) In the event that the Letter of Credit Issuer makes any payment under any Letter of Credit issued by it and the US Borrower or the UK Borrower, as the case may be, shall not have repaid such amount in full to the Letter of Credit Issuer pursuant to Section 3.4(a), the Letter of Credit Issuer shall promptly notify the Administrative Agent who will notify each applicable L/C Participant of such failure, and each such L/C Participant shall promptly and unconditionally pay to the Administrative Agent, for the account of the Letter of Credit Issuer, the amount of such L/C Participant’s Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of such unreimbursed payment in Dollars or in the applicable Foreign Currency, as the case may be, and in immediately available funds; provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Revolving Credit Commitment Percentage or

Extended Revolving Credit Commitment Percentage, as applicable, of such unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer. If the Letter of Credit Issuer so notifies, prior to 11:00 a.m. (Local Time) on any Business Day, any L/C Participant required to fund a payment under a Letter of Credit, such L/C Participant shall make available to the Administrative Agent for the account of the Letter of Credit Issuer such L/C Participant’s Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of the amount of such payment on such Business Day in immediately available funds (or, if such notification is given after 11:00 a.m. (Local Time) on any Business Day, such amount shall be made available on the immediately following Business Day). If and to the extent such L/C Participant shall not have so made its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of the amount of such payment available to the Administrative Agent for the account of the Letter of Credit Issuer, such L/C Participant agrees to pay to the Administrative Agent for the account of the Letter of Credit Issuer, forthwith on demand, such amount, together with interest thereon for each day from such date until the date such amount is paid to the Administrative Agent for the account of the Letter of Credit Issuer at the Federal Funds Effective Rate. The failure of any L/C Participant to make available to the Administrative Agent for the account of the Letter of Credit Issuer its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of any payment under any Letter of Credit shall not relieve any other L/C Participant of its obligation hereunder to make available to the Administrative Agent for the account of the Letter of Credit Issuer its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of any payment under such Letter of Credit on the date required, as specified above, but no L/C Participant shall be responsible for the failure of any other L/C Participant to make available to the Administrative Agent such other L/C Participant’s Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of any such payment.

(d) Whenever the Letter of Credit Issuer receives a payment in respect of an unpaid reimbursement obligation as to which the Administrative Agent has received for the account of the Letter of Credit Issuer any payments from the L/C Participants pursuant to paragraph (c) above, the Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each L/C Participant that has paid its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of such reimbursement obligation, in Dollars or the applicable Foreign Currency, as the case may be, and in immediately available funds, an amount equal to such L/C Participant’s share (based upon the proportionate aggregate amount originally funded by such L/C Participant to the aggregate amount funded by all L/C Participants) of the principal amount of such reimbursement obligation and interest thereon accruing after the purchase of the respective L/C Participations.

(e) The obligations of the L/C Participants to make payments to the Administrative Agent for the account of the Letter of Credit Issuer with respect to Letters

of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including under any of the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the other Credit Documents;

(ii) the existence of any claim, set-off, defense or other right that the US Borrower or the UK Borrower, as the case may be, may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, the Letter of Credit Issuer, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the US Borrower or the UK Borrower and the beneficiary named in any such Letter of Credit);

(iii) any draft, certificate or any other document presented under any 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;

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents; or

(v) the occurrence of any Default or Event of Default;

provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of any unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer.

3.4. Agreement to Repay Letter of Credit Drawings. (a) The US Borrower or the UK Borrower, as the case may be, hereby agrees to reimburse the Letter of Credit Issuer, by making payment to the Administrative Agent in Dollars or in the applicable Foreign Currency, as the case may be, in immediately available funds at the Administrative Agent’s Office, for any payment or disbursement made by the Letter of Credit Issuer under any Letter of Credit (each such amount (including the Dollar Equivalent thereof) so paid until reimbursed, an “Unpaid Drawing”) immediately after, and in any event on the date of, such payment, with interest on the amount so paid or disbursed by the Letter of Credit Issuer, to the extent not reimbursed prior to 5:00 p.m. (Local Time) on the date of such payment or disbursement, from and including the date paid or disbursed to but excluding the date the Letter of Credit Issuer is reimbursed therefor at a rate per annum that shall at all times be the Applicable ABR Margin plus the ABR as in effect from time to time; provided, that, notwithstanding anything contained in this Agreement to the contrary, (i) unless the US Borrower or the UK Borrower, as the

case may be, shall have notified the Administrative Agent and the Letter of Credit Issuer prior to 10:00 a.m. (Local Time) on the date of such drawing that the US Borrower or the UK Borrower, as the case may be, intends to reimburse the Letter of Credit Issuer for the amount of such drawing with funds other than the proceeds of Loans, the US Borrower or the UK Borrower, as the case may be, shall be deemed to have given a Notice of Borrowing to the Administrative Agent requesting that the Lenders make Dollar Revolving Credit Loans or Dollar Extended Revolving Credit Loans, as applicable, (each of which shall initially be ABR Loans) or Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans (each of which shall be Eurodollar Loans with an Interest Period of one month denominated in Sterling or Euro), as the case may be, on the date on which such drawing is honored in an amount equal to the amount of such drawing and (ii) the Administrative Agent shall promptly notify each L/C Participant of such drawing and the amount of its Revolving Credit Loan or Extended Revolving Credit Loan, as applicable, to be made in respect thereof, and (x) in respect of Dollar Letters of Credit, each L/C Participant shall be irrevocably obligated to make a Dollar Revolving Credit Loan or a Dollar Extended Revolving Credit Loan, as applicable, in each case that is an ABR Loan to the US Borrower or the UK Borrower, as the case may be, in the amount of its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of the applicable Unpaid Drawing by 12:00 noon (Local Time) on such Business Day by making the amount of such Dollar Revolving Credit Loan or Dollar Extended Revolving Credit Loan, as applicable, available to the Administrative Agent at the Administrative Agent’s Office and (y) in respect of Foreign Currency Letters of Credit, each L/C Participant shall be irrevocably obligated to make a Foreign Currency Revolving Credit Loan or a Foreign Currency Extended Revolving Credit Loan, as applicable, in each case that is a Eurodollar Loan with an Interest Period of one month to the US Borrower or the UK Borrower, as the case may be, denominated in Sterling or Euro, as the case may be, in the amount of its Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, of the applicable Unpaid Drawing by 12:00 noon (London time) on such Business Day by making the amount of such Foreign Currency Revolving Credit Loan or Foreign Currency Extended Revolving Credit Loan, as applicable, available to the Administrative Agent at the Administrative Agent’s Office. Such Dollar Revolving Credit Loans or Dollar Extended Revolving Credit Loans, Foreign Currency Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans, as the case may be, shall be made without regard to the Minimum Borrowing Amount. The Administrative Agent shall use the proceeds of such Revolving Credit Loans or Extended Revolving Credit Loans, as applicable, solely for the purpose of reimbursing the Letter of Credit Issuer for the related Unpaid Drawing.

(b) The US Borrower’s and the UK Borrower’s obligations under this Section 3.4 to reimburse the Letter of Credit Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment that the US Borrower, the UK Borrower or any other Person may have or have had against the Letter of Credit Issuer, the Administrative Agent or any Lender (including in its capacity as an L/C Participant), including any defense based upon the failure of any drawing under a Letter of Credit (each a “Drawing”) to conform to the terms of the Letter

of Credit or any non-application or misapplication by the beneficiary of the proceeds of such Drawing; provided, that the US Borrower or the UK Borrower, as the case may be, shall not be obligated to reimburse the Letter of Credit Issuer for any wrongful payment made by the Letter of Credit Issuer under the Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer.

3.5. Increased Costs. If after the Funding Date, the adoption of any applicable law, rule or regulation, or any change therein, 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 actual compliance by the Letter of Credit Issuer or any L/C Participant with any request or directive made or adopted after the Funding Date (whether or not having the force of law), by any such authority, central bank or comparable agency shall either (a) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by the Letter of Credit Issuer, or any L/C Participant’s L/C Participation therein, or (b) impose on the Letter of Credit Issuer or any L/C Participant any other conditions affecting its obligations under this Agreement in respect of Letters of Credit or L/C Participations therein or any Letter of Credit or such L/C Participant’s L/C Participation therein, and the result of any of the foregoing is to increase the cost to the Letter of Credit Issuer or such L/C Participant of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by the Letter of Credit Issuer or such L/C Participant hereunder (other than any such increase or reduction attributable to taxes) in respect of Letters of Credit or L/C Participations therein, then, promptly after receipt of written demand to the US Borrower or the UK Borrower, as the case may be, by the Letter of Credit Issuer or such L/C Participant, as the case may be, (a copy of which notice shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent), the US Borrower or the UK Borrower, as the case may be, shall pay to the Letter of Credit Issuer or such L/C Participant such additional amount or amounts as will compensate the Letter of Credit Issuer or such L/C Participant for such increased cost or reduction, it being understood and agreed, however, that the Letter of Credit Issuer or an L/C Participant shall not be entitled to such compensation as a result of such Person’s compliance with, or pursuant to any request or directive to comply with, any such law, rule or regulation as in effect on the Funding Date. A certificate submitted to the US Borrower or the UK Borrower, as the case may be, by the Letter of Credit Issuer or a L/C Participant, as the case may be, (a copy of which certificate shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent) setting forth in reasonable detail the basis for the determination of such additional amount or amounts necessary to compensate the Letter of Credit Issuer or such L/C Participant as aforesaid shall be conclusive and binding on the US Borrower and the UK Borrower absent clearly demonstrable error.

3.6. Successor Letter of Credit Issuer. The Letter of Credit Issuer may resign as Letter of Credit Issuer upon 60 days’ prior written notice to the Administrative Agent, the Lenders and the US Borrower. If the Letter of Credit Issuer shall resign as Letter of Credit Issuer under this Agreement, then the US Borrower shall appoint from among the Lenders with Extended Revolving Credit Commitments a successor issuer of

Letters of Credit, whereupon such successor issuer shall succeed to the rights, powers and duties of the Letter of Credit Issuer, and the term “Letter of Credit Issuer” shall mean such successor issuer effective upon such appointment. At the time such resignation shall become effective, the US Borrower and the UK Borrower shall pay to the resigning Letter of Credit Issuer all accrued and unpaid fees pursuant to Sections 4.1(d) and (e). The acceptance of any appointment as the Letter of Credit Issuer hereunder by a successor Lender shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the US Borrower and the Administrative Agent and, from and after the effective date of such agreement, such successor Lender shall have all the rights and obligations of the previous Letter of Credit Issuer under this Agreement and the other Credit Documents. After the resignation of the Letter of Credit Issuer hereunder, the resigning Letter of Credit Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a Letter of Credit Issuer under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit. After any retiring Letter of Credit Issuer’s resignation as Letter of Credit Issuer, the provisions of this Agreement relating to the Letter of Credit Issuer shall inure to its benefit as to any actions taken or omitted to be taken by it (a) while it was Letter of Credit Issuer under this Agreement or (b) at any time with respect to Letters of Credit issued by such Letter of Credit Issuer.

3.7. Defaulting Lenders and Letters of Credit. If any Letter of Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then:

(a) all or any part of such Letter of Credit Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Extended Revolving Credit Commitment Percentage but only to the extent (x) the sum of all non-Defaulting Lenders’ Extended Revolving Credit Exposures plus such Defaulting Lender’s Letter of Credit Exposure does not exceed the total of all non-Defaulting Lenders’ Extended Revolving Credit Commitments and (y) no Default or Event of Default exists and is continuing;

(b) if the reallocation described in clause (a) above cannot, or can only partially, be effected, the US Borrower shall within one Business Day following notice by the Administrative Agent cash collateralize such Defaulting Lender’s Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (a) above) in accordance with the procedures set forth in Section 5.2(b) for so long as such Letter of Credit Exposure is outstanding;

(c) if the US Borrower cash collateralizes any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to Section 3.7(b), the US Borrower shall not be required to pay any fees to such Defaulting Lender with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Letter of Credit Exposure is cash collateralized;

(d) if the Letter of Credit Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 3.7(a), then the fees payable to the Lenders pursuant to

Sections 4.1(c) or (d) shall be adjusted in accordance with such non-Defaulting Lenders’ Extended Revolving Credit Commitment Percentages; or

(e) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 3.7(a), then, without prejudice to any rights or remedies of the Letter of Credit Issuer or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Exposure) and Letter of Credit Fees payable under Sections 4.1(c) or (d) with respect to such Defaulting Lender’s Letter of Credit Exposure shall be payable to the Letter of Credit Issuer until such Letter of Credit Exposure is cash collateralized and/or reallocated.

So long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is reasonably satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 3.7(c).

(ii) Not later than the date that is six months after the last day of any fiscal year (commencing with the fiscal year ending December 31, 2004), if the Consolidated Total Debt to Consolidated EBITDA Ratio as of the end of such fiscal year is greater than or equal to 3.50 to 1.00, the US Borrower and the UK Borrower shall offer to prepay, in accordance with paragraph (c) below, the principal of Term Loans in an amount equal to (w) 50% of Excess Cash Flow for such fiscal year, minus (x) the amount of any such Excess Cash Flow that the US Borrower has, after the end of such fiscal year and prior to such date, reinvested in the business of the US Borrower or any of its Subsidiaries (subject to Section 9.14), minus (y) the principal amount of Term Loans voluntarily prepaid pursuant to Section 5.1 during such fiscal year and minus (z) an amount equal to $10,000,000 for such fiscal year.

(b) Aggregate Revolving Credit Outstandings and Aggregate Extended Revolving Credit Outstandings. If on any date the aggregate amount of the Lenders’ Revolving Credit Exposures (all the foregoing, collectively, the “Aggregate Revolving Credit Outstandings”) exceeds 103% of the Total Revolving Credit Commitment as then in effect or the aggregate amount of the Lenders’ Extended Revolving Credit Exposures (all the foregoing, collectively, the “Aggregate Extended Revolving Credit Outstandings”) exceeds 103% of the Total Extended Revolving Credit Commitment as then in effect, the US Borrower and/or the UK Borrower, as the case may be, shall forthwith repay on such date the principal amount of Swingline Loans and, after all Swingline Loans have been paid in full, Revolving Credit Loans or Extended Revolving Credit Loans, as applicable, in an amount equal to such excess. If, after giving effect to the prepayment of all outstanding Swingline Loans and Revolving Credit Loans or Extended Revolving Credit Loans, as applicable, the Aggregate Revolving Credit Outstandings exceed the Total Revolving Credit Commitment then in effect or the Aggregate Extended Revolving Credit Outstandings exceed the Total Extended Revolving Credit Commitment then in effect, as applicable, the US Borrower and/or the UK Borrower, as the case may be, shall pay to the Administrative Agent an amount in cash equal to such excess and the Administrative Agent shall hold such payment for the benefit of the Lenders as security for the obligations of the US Borrower and the UK Borrower hereunder (including obligations in respect of Letter of Credit Outstandings) pursuant to a cash collateral agreement to be entered into in form and substance satisfactory to the Administrative Agent (which shall permit certain investments in Permitted Investments satisfactory to the Administrative Agent, until the proceeds are applied to the secured obligations).

(c) Application to Repayment Amounts. Each prepayment of Term Loans required by Section 5.2(a) shall (unless otherwise indicated below) be initially allocated pro rata among the Tranche A-1 Term Loans, the Tranche A-2 Term Loans, the Tranche E Term Loans, the Tranche G Term Loans, the Tranche H Term Loans and the Tranche I Term Loans and each such prepayment of Term Loans (including those prepayments described below) shall be applied to reduce the applicable Repayment Amounts in such order as the US Borrower (on its own behalf and on behalf of the UK Borrower) may determine up to an amount equal to the aggregate amount of the applicable Repayment Amounts required to be made by the US Borrower or the UK Borrower pursuant to Section 2.5(b)(i), (ii), (iii), (iv), (v) or (vi), as the case may be, during the two year period

101

immediately following the date of the prepayment (such amount being, the “Amortization Amount”); provided, that to the extent that the amount of the prepayment exceeds the Amortization Amount, such excess shall be applied ratably to reduce the then remaining Repayment Amounts under such Term Facility; provided further, that, notwithstanding anything to the contrary contained herein, with respect to any prepayment of Term Loans required by Section 5.2(a) that results from a Debt Incurrence Prepayment Event in respect of any incurrence of Incremental Refinancing Term Loans pursuant to Section 2.15, any incurrence of Indebtedness pursuant to clause (ii) of Section 10.1(n) and any incurrence of Indebtedness pursuant to Section 10.1(q), such prepayment shall be initially allocated pro rata among the Tranche A-1 Term Loans, the Tranche A-2 Term Loans, the Tranche E Term Loans and the Tranche G Term Loans until such time as all such Term Loans have been repaid in full and, other than with respect to a Debt Incurrence Prepayment Event in respect of any incurrence of Indebtedness pursuant to Section 10.1(q), thereafter, pro rata among the remaining Term Loans. With respect to each such prepayment, (i) the US Borrower (on its own behalf and on behalf of the UK Borrower) will, not later than the date specified in Section 5.2(a) for offering to make such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing) requesting that the Administrative Agent provide notice of such prepayment to each Term Loan Lender, (ii) each Tranche E Term Loan Lender, each Tranche G Term Loan Lender, each Tranche H Term Loan Lender and each Tranche I Term Loan Lender will have the right to refuse any such prepayment by giving written notice of such refusal to the Administrative Agent within fifteen Business Days after such Lender’s receipt of notice from the Administrative Agent of such prepayment (and the US Borrower and the UK Borrower shall not prepay any such Tranche E Term Loans, Tranche G Term Loan, Tranche H Term Loans and Tranche I Term Loans until the date that is specified in the immediately following clause), (iii) the US Borrower and the UK Borrower will make all such prepayments not so refused upon the earlier of (x) such fifteenth Business Day and (y) such time as the Administrative Agent has received notice from each Lender that it consents to or refuses such prepayment and (iv) any prepayment so refused may be retained by the US Borrower or the UK Borrower, as the case may be; provided, that any prepayment so refused that relates to Net Cash Proceeds from a Debt Incurrence Prepayment Event in respect of the issuance of Permitted Additional Subordinated Notes shall be allocated pro rata to the then outstanding Tranche A-1 Term Loans and Tranche A-2 Term Loans and shall be applied as set forth above in this paragraph (c).

(d) Application to Term Loans. With respect to each prepayment of Term Loans required by Section 5.2(a), the US Borrower (on its own behalf and on behalf of the UK Borrower) may, subject to Section 5.2(c), designate the Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant to which made; provided, that (i) Eurodollar Term Loans may be designated for prepayment pursuant to this Section 5.2 only on the last day of an Interest Period applicable thereto unless all Eurodollar Term Loans with Interest Periods ending on such date of required prepayment and all Term Loans that are ABR Loans have been paid in full; (ii) if any prepayment of Eurodollar Term Loans made pursuant to a single Borrowing shall reduce the outstanding Term Loans made pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount for Eurodollar Term Loans, such Borrowing shall immediately be converted into ABR Loans; and (iii) in the case of a prepayment of Tranche E Term Loans or Tranche G

102

Term Loans required by Section 5.2(a), the prepayment amount shall be applied on a pro rata basis to the then outstanding Loans of the applicable Class, regardless of Type and, in the case of Eurodollar Term Loans of the applicable Class, the Interest Period therefor. In the absence of a designation by the US Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under Section 2.11.

(e) Application to Revolving Credit Loans and Extended Revolving Credit Loans. With respect to each prepayment of Revolving Credit Loans or Extended Revolving Credit Loans elected by the US Borrower pursuant to Section 5.1 or required by Section 5.2(b), the US Borrower (on its own behalf and on behalf of the UK Borrower) may designate (i) the Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant to which made and (ii) the Dollar Revolving Credit Loans, Foreign Currency Revolving Credit Loans, Dollar Extended Revolving Credit Loans or Foreign Currency Extended Revolving Credit Loans to be prepaid; provided, that (w) Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans may be designated for prepayment pursuant to this Section 5.2 only on the last day of an Interest Period applicable thereto unless all Eurodollar Revolving Credit Loans or all Eurodollar Extended Revolving Credit Loans, as applicable, with Interest Periods ending on such date of required prepayment and all ABR Loans have been paid in full; (x) if any prepayment by the US Borrower of Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans made pursuant to a single Borrowing shall reduce the outstanding Dollar Equivalent of the Revolving Credit Loans or Extended Revolving Credit Loans, as applicable, made pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount for Eurodollar Revolving Credit Loans or Eurodollar Extended Revolving Credit Loans, as applicable, such Borrowing shall immediately be converted into ABR Loans; (y) each prepayment of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans; and (z) notwithstanding the provisions of the preceding clause (y), no prepayment made pursuant to Section 5.2(a) or Section 5.2(b) of Revolving Credit Loans or Extended Revolving Credit Loans shall be applied to the Revolving Credit Loans or Extended Revolving Credit Loans of any Defaulting Lender. In the absence of a designation by the US Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under Section 2.11.

(f) Eurodollar Interest Periods. In lieu of making any payment pursuant to this Section 5.2 in respect of any Eurodollar Loan other than on the last day of the Interest Period therefor so long as no Default or Event of Default shall have occurred and be continuing, the US Borrower or the UK Borrower, as the case may be, at its option may deposit with the Administrative Agent an amount equal to the amount of the Eurodollar Loan to be prepaid and such Eurodollar Loan shall be repaid on the last day of the Interest Period therefor in the required amount. Such deposit shall be held by the Administrative Agent in a corporate time deposit account established on terms reasonably satisfactory to the Administrative Agent, earning interest at the then-customary rate for accounts of such type. Such deposit shall constitute cash collateral for the Obligations;

103

provided, that the US Borrower or the UK Borrower, as the case may be, may at any time direct that such deposit be applied to make the applicable payment required pursuant to this Section 5.2.

(g) Minimum Amount. No prepayment shall be required pursuant to Section 5.2(a)(i) unless and until the amount at any time of Net Cash Proceeds from Prepayment Events required to be applied at or prior to such time pursuant to such Section and not yet applied at or prior to such time to prepay Term Loans pursuant to such Section exceeds the Dollar Equivalent of $15,000,000 in the aggregate.

(h) Foreign Asset Sales. Notwithstanding any other provisions of this Section 5.2, (i) to the extent that any of or all the Net Cash Proceeds of any asset sale by a Restricted Foreign Subsidiary giving rise to an Asset Sale Prepayment Event (a “Foreign Asset Sale”) are prohibited or delayed by applicable local law from being repatriated to the United States or the United Kingdom, the portion of such Net Cash Proceeds so affected will not be required to be applied to repay Term Loans at the times provided in this Section 5.2 but may be retained by the applicable Restricted Foreign Subsidiary so long, but only so long, as the applicable local law will not permit repatriation to the United States or the United Kingdom (the US Borrower and the UK Borrower hereby agreeing to cause the applicable Restricted Foreign Subsidiary to promptly take all actions required by the applicable local law to permit such repatriation), and once such repatriation of any of such affected Net Cash Proceeds is permitted under the applicable local law, such repatriation will be immediately effected and such repatriated Net Cash Proceeds will be promptly (and in any event not later than two Business Days after such repatriation) applied (net of additional taxes payable or reserved against as a result thereof) to the repayment of the Term Loans pursuant to this Section 5.2 and (ii) to the extent that the US Borrower (on its own behalf and on behalf of the UK Borrower) has determined in good faith that repatriation of any of or all the Net Cash Proceeds of any Foreign Asset Sale would have a material adverse tax cost consequence with respect to such Net Cash Proceeds, the Net Cash Proceeds so affected may be retained by the applicable Restricted Foreign Subsidiary; provided, that, in the case of this clause (ii), on or before the date on which any Net Cash Proceeds so retained would otherwise have been required to be applied to reinvestments or prepayments pursuant to Section 5.2(a), (x) the US Borrower or the UK Borrower, as the case may be, applies an amount equal to such Net Cash Proceeds to such reinvestments or prepayments as if such Net Cash Proceeds had been received by the US Borrower or the UK Borrower, as the case may be, rather than such Restricted Foreign Subsidiary, less the amount of additional taxes that would have been payable or reserved against if such Net Cash Proceeds had been repatriated (or, if less, the Net Cash Proceeds that would be calculated if received by such Foreign Subsidiary) or (y) such Net Cash Proceeds are applied to the repayment of Indebtedness of a Restricted Foreign Subsidiary.

5.3. Method and Place of Payment. (a) Except as otherwise specifically provided herein, all payments under this Agreement shall be made by the US Borrower or the UK Borrower, without set-off, counterclaim or deduction of any kind, to the Administrative Agent for the ratable account of the Lenders entitled thereto, the Letter of Credit Issuer or the Swingline Lender, as the case may be, not later than

104

12:00 Noon (Local Time) on the date when due and shall be made (i) in the case of amounts payable in Dollars, in immediately available funds at the Administrative Agent’s Office and (ii) in the case of amounts payable in a Foreign Currency, in immediately available funds at the Administrative Agent’s Office or at such other office as the Administrative Agent shall specify for such purpose by notice to the Borrower, it being understood that written or facsimile notice by the US Borrower or the UK Borrower, as the case may be, to the Administrative Agent to make a payment from the funds in the US Borrower’s or the UK Borrower’s, as the case may be, account at the Administrative Agent’s Office shall constitute the making of such payment to the extent of such funds held in such account. All payments under each Credit Document (whether of principal, interest or otherwise) shall be made (i) in the case of the principal of and interest on each Loan, in the currency in which such Loan is denominated, (ii) in the case of reimbursement obligations in respect of Letters of Credit, in the currency in which such Letter of Credit is denominated, (iii) in the case of any indemnification or expense reimbursement payment, in Dollars or Euro, as requested by the Person entitled to receive such payment, or (iv) in all other cases, in Dollars, in each case except as otherwise expressly provided herein. The Administrative Agent will thereafter cause to be distributed on the same day (if payment was actually received by the Administrative Agent prior to 2:00 p.m. (Local Time) on such day) like funds relating to the payment of principal or interest or Fees ratably to the Lenders entitled thereto.

(b) Any payments under this Agreement that are made later than 2:00 p.m. (Local Time) shall be deemed to have been made on the next succeeding Business Day at the Administrative Agent’s discretion. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension.

5.4. Net Payments. (a) All payments made by the US Borrower and the UK Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any current or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding (i) net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent or any Lender and (ii) any taxes imposed on the Administrative Agent or any Lender as a result of a current or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes)

105

interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that the US Borrower shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof (a “Non-U.S. Lender”) if such Lender fails to comply with the requirements of paragraph (b) of this Section 5.4. Whenever any Non-Excluded Taxes are payable by the US Borrower or the UK Borrower, as the case may be, as promptly as possible thereafter such US Borrower or UK Borrower shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt (or other evidence acceptable to such Lender, acting reasonably) received by such US Borrower or the UK Borrower showing payment thereof. In addition, if the US Borrower or the UK Borrower, as the case may be, fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the US Borrower or the UK Borrower, as the case may be, shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest, costs or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. The agreements in this Section 5.4(a) shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(b) Each Non-U.S. Lender shall:

(i) deliver to the US Borrower and the Administrative Agent two copies of either (x) in the case of Non-U.S. Lender claiming exemption from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, United States Internal Revenue Service Form W-8BEN (together with a certificate representing that such Non-U.S. Lender is not a bank for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the US Borrower and is not a controlled foreign corporation related to the US Borrower (within the meaning of Section 864(d)(4) of the Code)), or (y) Internal Revenue Service Form W-8BEN or Form W-8ECI, in each case properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S. Federal withholding tax on payments by the US Borrower under this Agreement;

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

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

unless in any such case any change in treaty, law or regulation has occurred prior to the date on which any such delivery would otherwise be required that renders any such form

106

inapplicable or would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the US Borrower and the Administrative Agent. Each Person that shall become a Participant pursuant to Section 14.6 or a Lender pursuant to Section 14.6 shall, upon the effectiveness of the related transfer, be required to provide all the forms and statements required pursuant to this Section 5.4(b); provided, that in the case of a Participant such Participant shall furnish all such required forms and statements to the Lender from which the related participation shall have been purchased. Notwithstanding anything to the contrary, no Lender or Participant shall be required to deliver any form or certification that it is not legally able to deliver.

(c) The US Borrower shall not be required to indemnify any Non-U.S. Lender, or to pay any additional amounts to any Non-U.S. Lender, in respect of U.S. Federal withholding tax pursuant to paragraph (a) above to the extent that (i) the obligation to withhold amounts with respect to U.S. Federal withholding tax existed on the date such Non-U.S. Lender became a party to this Agreement (or, in the case of a Participant that is not organized under the laws of the United States of America or a state thereof (a “Non-U.S. Participant”), on the date such Non-U.S. Participant became a Participant hereunder); provided, however, that this clause (i) shall not apply to the extent that (x) the indemnity payments or additional amounts any Lender (or Participant) would be entitled to receive (without regard to this clause (i)) do not exceed the indemnity payment or additional amounts that the person making the assignment, participation or transfer to such Lender (or Participant) would have been entitled to receive in the absence of such assignment, participation or transfer, or (y) such assignment, participation or transfer had been requested by the US Borrower or the UK Borrower, (ii) the obligation to pay such additional amounts would not have arisen but for a failure by such Non U.S. Lender or Non U.S. Participant to comply with the provisions of paragraph (b) above or (iii) any of the representations or certifications made by a Non-U.S. Lender or Non-U.S. Participant pursuant to paragraph (b) above are incorrect at the time a payment hereunder is made, other than by reason of any change in treaty, law or regulation having effect after the date such representations or certifications were made.

(d) Where a Lender is not, or has ceased to be, an Eligible Lender on the due date for payment of any sum under this Agreement, the increased amount due under Section 5.4(a) hereof shall be limited to the amount the UK Borrower would have had to pay if:

(i) where that Lender had been a UK Lender before ceasing to be an Eligible Lender, the Lender had remained a UK Lender;

(ii) where that Lender had been a Treaty Lender before ceasing to be an Eligible Lender, the Lender had remained a Treaty Lender and an appropriate direction had been given by the United Kingdom Inland Revenue authorizing the UK Borrower to make payment with deduction of tax at a reduced rate in accordance with the provisions of the relevant double taxation agreement; or

107

(iii) where that Lender had not been a Eligible Lender, the Lender had been a UK Lender;

this Section 5.4(d) shall not apply to the extent that the UK Borrower would have been required to make a deduction or withholding on account of tax regardless of whether such Lender is an Eligible Lender.

This Section 5.4(d) shall not apply in circumstances where a Lender ceases to be an Eligible Lender due to a change in the Requirement of Law or double taxation treaty or in its application or interpretation, in each case taking effect after the Funding Date.

(e) If the US Borrower or the UK Borrower determines in good faith that a reasonable basis exists for contesting any taxes for which indemnification has been demanded hereunder, the relevant Lender or the Administrative Agent, as applicable, shall cooperate with such US Borrower or UK Borrower in challenging such taxes at such US Borrower’s or UK Borrower’s expense if so requested by such US Borrower or UK Borrower. If any Lender or the Administrative Agent, as applicable, receives a refund of a tax for which a payment has been made by the US Borrower or the UK Borrower pursuant to this Agreement, which refund in the good faith judgment of such Lender or Administrative Agent, as the case may be, is attributable to such payment made by such US Borrower or UK Borrower, then the Lender or the Administrative Agent, as the case may be, shall reimburse such US Borrower or UK Borrower for such amount (together with any interest received thereon) as the Lender or Administrative Agent, as the case may be, determines to be the proportion of the refund as will leave it, after such reimbursement, in no better or worse position than it would have been in if the payment had not been required. A Lender or Administrative Agent shall claim any refund that it determines is available to it, unless it concludes in its reasonable discretion that it would be adversely affected by making such a claim. Neither any Lender nor the Administrative Agent shall be obliged to disclose any information regarding its tax affairs or computations to the US Borrower or the UK Borrower in connection with this paragraph (e) or any other provision of this Section 5.4.

(f) Each Lender represents and agrees that, on the Funding Date and at all times during the term of this Agreement, it is not and will not be a conduit entity participating in a conduit financing arrangement (as defined in Section 7701(1) of the Code and the regulations thereunder) with respect to the Borrowings hereunder unless the US Borrower has consented to such arrangement prior thereto.

5.5. Computations of Interest and Fees. (a) Interest on Eurodollar Loans and, except as provided in the next succeeding sentence, ABR Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. Interest on (i) Foreign Currency Revolving Credit Loans and Foreign Currency Extended Revolving Credit Loans denominated in Sterling and (ii) ABR Loans in respect of which the rate of interest is calculated on the basis of the Prime Rate and interest on overdue interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed.

108

(b) Fees and Letter of Credit Outstanding shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed.

It is understood and agreed that any period available for the delivery of documents and the taking of actions provided by this Section 9.18 shall not be in addition to, and shall run concurrently with, any Clean-Up Period provided in Section 7.4.

One or more judgments or decrees shall be entered against the US Borrower, the UK Borrower or any of the Restricted Subsidiaries involving a liability of $30,000,000 or more in the aggregate for all such judgments and decrees for the US Borrower and the Restricted Subsidiaries (to the extent not paid or fully covered by insurance provided by a carrier not disputing coverage) and any such judgments or decrees shall not have been satisfied, vacated, discharged or stayed or bonded pending appeal within 60 days from the entry thereof; or

11.15. Change of Control. A Change of Control shall occur;

then, and in any such event, and at any time thereafter, in each case subject to Section 7.4, if any Event of Default shall then be continuing, the Administrative Agent shall, upon the written request of the Required Lenders, by written notice to the US Borrower, take any or all of the following actions, without prejudice to the rights of the Administrative Agent or any Lender to enforce its claims against the US Borrower and the UK Borrower, except as otherwise specifically provided for in this Agreement (provided, that, if an Event of Default specified in Section 11.5 shall occur with respect to the US Borrower, the UK Borrower or any Specified Subsidiary, the result that would occur upon the giving of written notice by the Administrative Agent as specified in clauses (i), (ii) and (iv) below shall occur automatically without the giving of any such notice): (i) declare the Total Term Loan Commitment, the Total Revolving Credit Commitment and the Total Extended Revolving Credit Commitment terminated, whereupon the Commitments and Swingline Commitment, if any, of each Lender or the Swingline Lender, as the case may be, shall forthwith terminate immediately and any Fees theretofore accrued shall forthwith become due and payable without any other notice of any kind; (ii) declare the principal of and any accrued interest in respect of all

155

Loans and all Obligations owing hereunder and thereunder to be, whereupon the same shall become, forthwith due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the US Borrower and the UK Borrower; (iii) terminate any Letter of Credit that may be terminated in accordance with its terms; and/or (iv) direct the US Borrower and the UK Borrower to pay (and the US Borrower and the UK Borrower agree that upon receipt of such notice, or upon the occurrence of an Event of Default specified in Section 11.5 with respect to the US Borrower, the UK Borrower or any Specified Subsidiary, it will pay) to the Administrative Agent at the Administrative Agent’s Office such additional amounts of cash, to be held as security for the US Borrower’s and the UK Borrower’s respective reimbursement obligations for Drawings that may subsequently occur thereunder, equal to the aggregate Stated Amount of all Letters of Credit issued and then outstanding.

SECTION 12. The Administrative Agent

12.1. Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Credit Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Credit Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Credit Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Credit Document or otherwise exist against the Administrative Agent. Neither Co-Syndication Agent, in its capacity as such, shall have any obligations, duties or responsibilities under this Agreement.

12.2. Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Credit Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

12.3. Exculpatory Provisions. Neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (a) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Credit Document (except for its or such Person’s own gross negligence or willful misconduct) or (b) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor, any other Credit Party or any officer thereof contained in this Agreement or any other Credit Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in

156

connection with, this Agreement or any other Credit Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Credit Document or for any failure of the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor or any other Credit Party to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Credit Document, or to inspect the properties, books or records of the US Borrower or the UK Borrower.

12.4. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the US Borrower and/or the UK Borrower), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the Lender specified in the Register with respect to any amount owing hereunder as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Credit Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Credit Documents in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

12.5. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent has received notice from a Lender or the US Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided, that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders (except to the extent that this Agreement requires that such action be taken only with the approval of the Required Lenders or each of the Lenders, as applicable).

157

12.6. Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Administrative Agent hereinafter taken, including any review of the affairs of the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor or any other Credit Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor and any other Credit Party and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Credit Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor and any other Credit Party. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, assets, operations, properties, financial condition, prospects or creditworthiness of the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor or any other Credit Party that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

12.7. Indemnification. The Lenders agree to indemnify the Administrative Agent in its capacity as such (to the extent not reimbursed by the US Borrower or the UK Borrower and without limiting the obligation of the US Borrower and the UK Borrower to do so), ratably according to their respective portions of the Total Credit Exposure in effect on the date on which indemnification is sought (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with their respective portions of the Total Credit Exposure in effect immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including at any time following the payment of the Loans) be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent under or in connection with any of the foregoing; provided, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages,

158

penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. The agreements in this Section 12.7 shall survive the payment of the Loans and all other amounts payable hereunder.

12.8. Administrative Agent in its Individual Capacity. The Administrative Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the US Borrower, the UK Borrower, any Guarantor, any Foreign Subsidiary Guarantor and any other Credit Party as though the Administrative Agent were not the Administrative Agent hereunder and under the other Credit Documents. With respect to the Loans made by it, the Administrative Agent shall have the same rights and powers under this Agreement and the other Credit Documents as any Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity.

12.9. Successor Agent. The Administrative Agent may resign as Administrative Agent upon 20 days’ prior written notice to the Lenders and the US Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Credit Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the US Borrower (which approval shall not be unreasonably withheld), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 12 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Credit Documents.

12.10. Withholding Tax. To the extent required by any applicable law, the Administrative Agent may withhold from any interest payment to any Lender an amount equivalent to any applicable withholding tax. If the Internal Revenue Service or any other Governmental Authority asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender because the appropriate form was not delivered or was not properly executed or because such Lender failed to notify the Administrative Agent of a change in circumstance which rendered the exemption from, or reduction of, withholding tax ineffective or for any other reason, such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including any penalties or interest and together with all expenses (including legal expenses, allocated internal costs and out-of-pocket expenses) incurred. For the avoidance of doubt, the foregoing shall have no effect on any obligations of the Borrowers hereunder.

159

SECTION 13. Collateral Allocation Mechanism

13.1. Implementation of CAM. (a) On the CAM Exchange Date, (i) the Commitments shall automatically and without further act be terminated as provided in Section 11, (ii) the Lenders shall automatically and without further act (and without regard to the provisions of Section 14.6) be deemed to have exchanged interests in the Credit Facilities such that in lieu of the interest of each Lender in each Credit Facility in which it shall participate as of such date (including such Lender’s interest in the Specified Obligations of each Credit Party in respect of each such Credit Facility), such Lender shall hold an interest in every one of the Credit Facilities (including the Specified Obligations of each Credit Party in respect of each such Credit Facility and each L/C Reserve Account established pursuant to Section 13.2 below), whether or not such Lender shall previously have participated therein, equal to such Lender’s CAM Percentage thereof and (iii) simultaneously with the deemed exchange of interests pursuant to clause (ii) above, in the case of any CAM Dollar Lender that has prior to the date thereof notified the Administrative Agent and the US Borrower in writing that it has elected to have this clause (iii) apply to it, the interests in the Loans to be received by such CAM Dollar Lender in such deemed exchange shall, automatically and with no further action required, be converted into the Dollar Equivalent, determined using the Exchange Rate calculated as of such date, of such amount and on and after such date all amounts accruing and owed to such CAM Dollar Lender in respect of such Obligations shall accrue and be payable in Dollars at the rate otherwise applicable hereunder; provided, that such CAM Exchange will not affect the aggregate amount of the Obligations of the US Borrower and the UK Borrower to the Lenders under the Credit Documents. Each Lender and each Credit Party hereby consents and agrees to the CAM Exchange, and each Lender agrees that the CAM Exchange shall be binding upon its successors and assigns and any person that acquires a participation in its interests in any Credit Facility. Each Credit Party agrees from time to time to execute and deliver to the Administrative Agent all promissory notes and other instruments and documents as the Administrative Agent shall reasonably request to evidence and confirm the respective interests of the Lenders after giving effect to the CAM Exchange, and each Lender agrees to surrender any promissory notes originally received by it in connection with its Loans hereunder to the Administrative Agent against delivery of new promissory notes evidencing its interests in the Credit Facilities; provided, however, that the failure of any Credit Party to execute or deliver or of any Lender to accept any such promissory note, instrument or document shall not affect the validity or effectiveness of the CAM Exchange.

(b) As a result of the CAM Exchange, upon and after the CAM Exchange Date, each payment received by the Administrative Agent pursuant to any Credit Document in respect of the Specified Obligations, and each distribution made by the Administrative Agent pursuant to any Credit Document in respect of the Specified Obligations, shall be distributed to the Lenders pro rata in accordance with their respective CAM Percentages. Any direct payment received by a Lender upon or after the CAM Exchange Date, including by way of setoff, in respect of a Specified Obligation shall be paid over to the Administrative Agent for distribution to the Lenders in accordance herewith.

160

13.2. Letters of Credit. (a) In the event that on the CAM Exchange Date any Letter of Credit shall be outstanding and undrawn in whole or in part, or any amount drawn under a Letter of Credit shall constitute an Unpaid Drawing, each Lender in respect of Unpaid Drawings on Letters of Credit shall, before giving effect to the CAM Exchange, promptly pay over to the Administrative Agent, in immediately available funds and in the currency that such Letters of Credit are denominated, an amount equal to such Lender’s Revolving Credit Commitment Percentage or Extended Revolving Credit Commitment Percentage, as applicable, (as notified to such Lender by the Administrative Agent), of such Letter of Credit’s undrawn face amount or (to the extent it has not already done so) such Letter of Credit’s Unpaid Drawing, as the case may be, together with interest thereon from the CAM Exchange Date to the date on which such amount shall be paid to the Administrative Agent at the rate that would be applicable at the time to an Extended Revolving Credit Loan or, with respect to Letters of Credit issued under the Revolving Credit Commitments, a Revolving Credit Loan, that is an ABR Loan in a principal amount equal to such amount, as the case may be. The Administrative Agent shall establish a separate account or accounts for each Lender (each, an “L/C Reserve Account”) for the amounts received with respect to each such Letter of Credit pursuant to the preceding sentence. The Administrative Agent shall deposit in each Lender’s L/C Reserve Account such Lender’s CAM Percentage of the amounts received from the Lenders as provided above. The Administrative Agent shall have sole dominion and control over each L/C Reserve Account, and the amounts deposited in each L/C Reserve Account shall be held in such L/C Reserve Account until withdrawn as provided in paragraph (b), (c), (d) or (e) below. The Administrative Agent shall maintain records enabling it to determine the amounts paid over to it and deposited in the L/C Reserve Accounts in respect of each Letter of Credit and the amounts on deposit in respect of each Letter of Credit attributable to each Lender’s CAM Percentage. The amounts held in each Lender’s L/C Reserve Account shall be held as a reserve against the Letter of Credit Exposure, shall be the property of such Lender, shall not constitute Loans to or give rise to any claim of or against any Credit Party and shall not give rise to any obligation on the part of the US Borrower or the UK Borrower to pay interest to such Lender, it being agreed that the reimbursement obligations in respect of Letters of Credit shall arise only at such times as drawings are made thereunder, as provided in Section 3.

(b) In the event that after the CAM Exchange Date any drawing shall be made in respect of a Letter of Credit, the Administrative Agent shall, at the request of the Letter of Credit Issuer withdraw from the L/C Reserve Account of each Lender any amounts, up to the amount of such Lender’s CAM Percentage of such drawing, deposited in respect of such Letter of Credit and remaining on deposit and deliver such amounts to the Letter of Credit Issuer in satisfaction of the reimbursement obligations of the Lenders under Section 3 (but not of the US Borrower and the UK Borrower under Section 3, respectively). In the event any Lender shall default on its obligation to pay over any amount to the Administrative Agent in respect of any Letter of Credit as provided in this Section 13.2, the Letter of Credit Issuer shall, in the event of a drawing thereunder, have a claim against such Lender to the same extent as if such Lender had defaulted on its obligations under Section 2.05(e), but shall have no claim against any other Lender in respect of such defaulted amount, notwithstanding the exchange of interests in the reimbursement obligations pursuant to Section 13.1. Each other Lender shall have a

161

claim against such defaulting Lender for any damages sustained by it as a result of such default, including, in the event such Letter of Credit shall expire undrawn, its CAM Percentage of the defaulted amount.

(c) In the event that after the CAM Exchange Date any Letter of Credit shall expire undrawn, the Administrative Agent shall withdraw from the L/C Reserve Account of each Lender the amount remaining on deposit therein in respect of such Letter of Credit and distribute such amount to such Lender.

(d) With the prior written approval of the Administrative Agent and the Letter of Credit Issuer, any Lender may withdraw the amount held in its L/C Reserve Account in respect of the undrawn amount of any Letter of Credit. Any Lender making such a withdrawal shall be unconditionally obligated, in the event there shall subsequently be a drawing under such Letter of Credit, to pay over to the Administrative Agent, for the account of the Letter of Credit Issuer on demand, its CAM Percentage of such drawing.

(e) Pending the withdrawal by any Lender of any amounts from its L/C Reserve Account as contemplated by the above paragraphs, the Administrative Agent will, at the direction of such Lender and subject to such rules as the Administrative Agent may prescribe for the avoidance of inconvenience, invest such amounts in Permitted Investments. Each Lender that has not withdrawn the amounts in its L/C Reserve Account as provided in paragraph (d) above shall have the right, at intervals reasonably specified by the Administrative Agent, to withdraw the earnings on investments so made by the Administrative Agent with amounts in its L/C Reserve Account and to retain such earnings for its own account.

13.3. Net Payments Upon Implementation of CAM Exchange. Notwithstanding any other provision of this Agreement, if, as a direct result of the implementation of the CAM Exchange, the US Borrower or the UK Borrower is required to withhold Non-Excluded Taxes from amounts payable to the Administrative Agent, any Lender or any Participant hereunder, the amounts so payable to the Administrative Agent, such Lender or such Participant shall be increased to the extent necessary to yield to the Administrative Agent, such Lender or such Participant (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that the US Borrower and the UK Borrower shall not be required to increase any such amounts payable to such Lender or Participant under this Section 13.3 (but, rather, shall be required to increase any such amounts payable to such Lender or Participant to the extent required by Section 5.4) if such Lender or Participant was prior to or on the CAM Exchange Date already a Lender or Participant with respect to such US Borrower or UK Borrower. If a Non-U.S. Lender (or Non-U.S. Participant), in its good faith judgment, is eligible for an exemption from, or reduced rate of, U.S. Federal withholding tax on payments by the US Borrower under this Agreement, the US Borrower shall not be required to increase any such amounts payable to such Non-U.S. Lender (or Non-U.S. Participant) if such Non-U.S. Lender (or Non-U.S. Participant) fails to comply with the requirements of paragraph (b) of Section 5.4. Upon a CAM Exchange, a Lender (or Participant) will use commercially

162

reasonable efforts, and complete any procedural formalities necessary, to become an Eligible Lender with respect to the UK Borrower and, if such Lender (or Participant) fails to do so, the UK Borrower shall not be required to increase any such amounts payable to such Lender (or Participant). If the US Borrower or the UK Borrower, as the case may be, fails to pay any such Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, such US Borrower or UK Borrower shall indemnify the Administrative Agent, the Lenders and the Participants for any incremental taxes, interest, costs or penalties that may become payable by the Administrative Agent, such Lenders or such Participants as a result of any such failure.

SECTION 14. Miscellaneous

14.1. Amendments and Waivers. Neither this Agreement nor any other Credit Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 14.1. The Required Lenders may, or, with the written consent of the Required Lenders, the Administrative Agent may, from time to time, (a) enter into with the relevant Credit Party or Credit Parties written amendments, supplements or modifications hereto and to the other Credit Documents for the purpose of adding any provisions to this Agreement or the other Credit Documents or changing in any manner the rights of the Lenders or of the Credit Parties hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Credit Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall directly (i) forgive any portion of any Loan or extend the final scheduled maturity date of any Loan or reduce the stated rate, or forgive any portion, or extend the date for the payment, of any interest or fee payable hereunder (other than as a result of waiving the applicability of any post-default increase in interest rates) or extend the final expiration date of any Lender’s Commitment or extend the final expiration date of any Letter of Credit beyond the L/C Maturity Date or increase the aggregate amount of the Commitments of any Lender, in each case without the written consent of each Lender directly and adversely affected thereby, or (ii) amend, modify or waive any provision of this Section 14.1 or reduce the percentages specified in the definitions of the terms “Required Lenders”, “Required Revolving Credit Lenders”, “Required Extended Revolving Credit Lenders”, “Required Tranche A Lenders”, “Required Tranche E Lenders”, “Required Tranche G Lenders”, “Required Tranche H Lenders”, “Required Tranche I Lenders” or consent to the assignment or transfer by the US Borrower or the UK Borrower of its rights and obligations under any Credit Document to which it is a party (except as permitted pursuant to Section 10.3), in each case without the written consent of each Lender directly and adversely affected thereby, or (iii) amend, modify or waive any provision of Section 12 without the written consent of the then-current Administrative Agent, or (iv) amend, modify or waive any provision of Section 3 without the written consent of the Letter of Credit Issuer, or (v) amend, modify or waive any provisions hereof relating to Swingline Loans without the written consent of the Swingline Lender, or (vi) change any Revolving Credit Commitment or Extended Revolving Credit Commitment to a Term

163

Loan Commitment, or change any Term Loan Commitment to a Revolving Credit Commitment or an Extended Revolving Credit Commitment, in each case without the prior written consent of each Lender directly and adversely affected thereby, or (vii) release all or substantially all of the Guarantors under the Guarantee (except as expressly permitted by the Guarantee Agreement), release all or substantially all of the Foreign Subsidiary Guarantors under any Foreign Subsidiary Guarantee (except as permitted by any Foreign Subsidiary Guarantee) or release all or substantially all of the Collateral under the Pledge Agreement, the Security Agreement, the Foreign Security Documents and the Mortgages, in each case without the prior written consent of each Lender, or (viii) decrease any Tranche A-1 Repayment Amount, extend any scheduled Tranche A-1 Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche A-1 Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche A Lenders, or (ix) decrease any Tranche A-2 Repayment Amount, extend any scheduled Tranche A-2 Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche A-2 Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche A Lenders, or (x) decrease any Tranche E Repayment Amount, extend any scheduled Tranche E Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche E Term Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche E Term Loan Lenders, or (xi) decrease any Tranche G Repayment Amount, extend any scheduled Tranche G Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche G Term Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche G Term Loan Lenders, or (xii) decrease any Tranche H Repayment Amount, extend any scheduled Tranche H Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche H Term Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche H Term Loan Lenders, (xiii) decrease any Tranche I Repayment Amount, extend any scheduled Tranche I Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender holding any Tranche I Term Loans (other than a decrease in such mandatory prepayment amount that is accompanied by a proportionate decrease in mandatory prepayments to be allocated to other Term Loans pursuant to Section 5.2(c)), in each case without the written consent of the Required Tranche I Term Loan Lenders; and; provided further, that at any time that no Default or

164

Event of Default has occurred and is continuing, the Revolving Credit Commitment of any Lender may be increased to finance a Permitted Acquisition, with the consent of such Lender, the US Borrower and the Administrative Agent (which consent, in the case of the Administrative Agent, shall not be unreasonably withheld) and without the consent of the Required Lenders, so long as (i) the Increased Commitment Amount at such time, when added to the amount of Indebtedness incurred pursuant to Section 10.1(k) and outstanding at such time, does not exceed the limits set forth therein, (ii) the US Borrower or its applicable Restricted Subsidiary shall pledge the capital stock of any person acquired pursuant thereto to the Administrative Agent for the benefit of the Lenders to the extent required under Section 9.12 and (iii) to the extent determined by the Administrative Agent to be necessary to ensure pro rata borrowings commencing with the initial borrowing after giving effect to such increase, the US Borrower shall prepay any Eurodollar Loans outstanding immediately prior to such initial borrowing; as used herein, the “Increased Commitment Amount” means, at any time, the aggregate amount of all increases pursuant to this proviso made at or prior to such time less the aggregate amount of all voluntary reductions of the Revolving Credit Commitments made prior to such time and provided further, that without the consent of any Lender, the relevant Credit Party or Credit Parties and the Administrative Agent and/or Collateral Agent may (in their respective sole discretion, or shall, to the extent required by any other Credit Document) enter into any amendment, modification or waiver of any Credit Document, or enter into any new agreement or instrument, to effect the granting, perfection, protection, expansion or enhancement of any security interest in any Collateral or additional property to become Collateral for the benefit of the Secured Parties, or as required by local law to give effect to, or protect any security interest for the benefit of the Secured Parties, in any property or so that the security interests therein comply with applicable law. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the affected Lenders and shall be binding upon the US Borrower, the UK Borrower, such Lenders, the Administrative Agent and all future holders of the affected Loans. In the case of any waiver, the US Borrower, the Lenders and the Administrative Agent shall be restored to their former positions and rights hereunder and under the other Credit Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing, it being understood that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Upon any sale or other transfer to any Person (other than the US Borrower and any Restricted Domestic Subsidiary) by any Credit Party of any Collateral that is permitted under the Credit Agreement, the relevant Credit Party, together with the Administrative Agent and/or Collateral Agent, shall be permitted, without consent of any Lender, to amend, modify or waive any provision of the Pledge Agreement, the Security Agreement, the Foreign Security Documents or the Mortgages, as applicable, to the extent necessary to effect release of the security interest in such Collateral.

14.6. Successors and Assigns; Participations and Assignments. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Letter of Credit Issuer that issues any Letter of Credit), except that

167

(i) other than as provided in Section 10.3, the US Borrower and the UK Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the US Borrower or the UK Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Letter of Credit Issuer that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Letter of Credit Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent (such consent not be unreasonably withheld; it being understood that, without limitation, the US Borrower shall have the right to withhold its consent to any assignment if, in order for such assignment to comply with applicable law, the US Borrower would be required to obtain the consent of, or make any filing or registration with, any Governmental Authority) of:

(A) the US Borrower; provided, that no consent of the US Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender (unless increased costs would result therefrom except if an Event of Default under Section 11.1 or Section 11.5 has occurred and is continuing), an Approved Fund or, if an Event of Default under Section 11.1 or Section 11.5 has occurred and is continuing, any other assignee; and

(B) the Administrative Agent and, in the case of an assignment of a Extended Revolving Credit Commitment, the Letter of Credit Issuer; provided, that no consent of the Administrative Agent shall be required for an assignment of any Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than the Dollar Equivalent of $5,000,000 or, in the case of a Tranche E Term Loan Commitment, Tranche G Term Loan Commitment, Tranche H Term Loan Commitment,

168

Tranche I Term Loan Commitment, Tranche E Term Loan, Tranche G Term Loan, Tranche H Term Loan or Tranche I Term Loan, the Dollar Equivalent of $1,000,000 unless each of the US Borrower and the Administrative Agent otherwise consents; provided, that no such consent of the US Borrower shall be required if an Event of Default under Section 11.1 or Section 11.5 has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; provided, that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans; provided further, however, that any assignment of any right or interest in a Tranche A-1 Term Loan, a Tranche A-2 Term Loan or a Tranche A Term Loan Commitment (collectively, “Tranche A Loans”) shall be accompanied by, and shall not be permitted to be made independently of, an assignment of a proportionate amount of such Lender’s other Tranche A Loans;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance (such Assignment and Acceptance to be (x) electronically executed and delivered to the Administrative Agent via an electronic settlement system then acceptable to the Administrative Agent, which shall initially be the settlement system of ClearPar, LLC or (y) manually executed and delivered together with a processing and recordation fee of $3,500; provided, that only one such fee shall be payable in the event of simultaneous assignments to or from two or more Approved Funds); and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in a form approved by the Administrative Agent.

For the purpose of this Section 14.6(b), the term “Approved Fund” has the following meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall,

169

to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.10, 2.11, 3.5, 5.4 and 14.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 14.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the US Borrower and the UK Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans and any payment made by the Letter of Credit Issuer under any Letter of Credit owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the US Borrower, the UK Borrower, the Administrative Agent, the Letter of Credit Issuer and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the US Borrower, the UK Borrower, the Letter of Credit Issuer and by the Administrative Agent on behalf of any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of the US Borrower, the UK Borrower, the Administrative Agent, the Letter of Credit Issuer or the Swingline Lender, sell participations to one or more banks or other entities (each, a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided, that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the US Borrower, the UK Borrower, the Administrative Agent, the Letter of Credit Issuer and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement or

170

any other Credit Document; provided, that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 14.1 that affects such Participant. Subject to paragraph (c)(ii) of this Section, the US Borrower and the UK Borrower agree that each Participant shall be entitled to the benefits of Sections 2.10, 2.11 and 5.4 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 14.8(b) as though it were a Lender; provided, such Participant agrees to be subject to Section 14.8(a) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.10 or 5.4 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the US Borrower’s prior written consent. A Participant that would be a Non-U.S. Lender if it were a Lender shall not be entitled to the benefits of Section 5.4 unless the US Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the US Borrower and the UK Borrower, to comply with Section 5.4(b) as though it were a Lender.

(d) Any Lender may, without the consent of the Borrower or the Administrative Agent, at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided, that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. In order to facilitate such pledge or assignment, the US Borrower and the UK Borrower hereby agree that, upon request of any Lender at any time and from time to time after the US Borrower has made its initial borrowing hereunder, the US Borrower or the UK Borrower, as the case may be, shall provide to such Lender, at the US Borrower’s or the UK Borrower’s own expense, a promissory note, substantially in the form of Exhibit R-1, R-2, R-3, R-4, R-5, R-6, R-7 or R-8, as the case may be, evidencing the Tranche A-1 Term Loans, Tranche A-2 Term Loans, Tranche E Term Loans, Tranche G Term Loans, Tranche H Term Loans, Tranche I Term Loans, Revolving Credit Loans, Extended Revolving Credit Loans and Swingline Loans, respectively, owing to such Lender.

(e) Subject to Section 14.16, the US Borrower and the UK Borrower authorize each Lender to disclose to any Participant, secured creditor of such Lender or assignee (each, a “Transferee”) and any prospective Transferee any and all financial information in such Lender’s possession concerning the US Borrower and its Affiliates that has been delivered to such Lender by or on behalf of the US Borrower and its Affiliates pursuant to this Agreement or which has been delivered to such Lender by or on behalf of the US Borrower and its Affiliates in connection with such Lender’s credit evaluation of the US Borrower and its Affiliates prior to becoming a party to this Agreement; provided, that neither the Administrative Agent nor any Lender shall provide

171

to any Transferee or prospective Transferee any of the Confidential Information unless such person shall have previously executed a Confidentiality Agreement in the form of Exhibit S.

14.7. Replacements of Lenders under Certain Circumstances. The US Borrower (on its own behalf and on behalf of the UK Borrower) shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.10, 2.11, 3.5 or 5.4, (b) is affected in the manner described in Section 2.10(a)(iii) and as a result thereof any of the actions described in such Section is required to be taken or (c) becomes a Defaulting Lender, with a replacement bank or other financial institution; provided, that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) the US Borrower and/or the UK Borrower, as applicable, shall repay (or the replacement bank or institution shall purchase, at par) all Loans and other amounts (other than any disputed amounts, pursuant to Section 2.10, 2.11, 3.5 or 5.4, as the case may be) owing to such replaced Lender prior to the date of replacement, (iv) the replacement bank or institution, if not already a Lender, and the terms and conditions of such replacement, shall be reasonably satisfactory to the Administrative Agent, (v) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 14.6 (provided, that the US Borrower shall be obligated to pay the registration and processing fee referred to therein) and (vi) any such replacement shall not be deemed to be a waiver of any rights that the US Borrower, the UK Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

14.8. Adjustments; Set-off. (a) If any Lender (a “benefited Lender”) shall at any time receive any payment of all or part of its Loans, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 11.5, or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Loans, or interest thereon, such benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Loan, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) After the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the US Borrower or the UK Borrower, any such notice being expressly waived by the US Borrower and the UK Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the US Borrower or the UK Borrower hereunder (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any

172

and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the US Borrower or the UK Borrower, as the case may be. Each Lender agrees promptly to notify the US Borrower or the UK Borrower, as the case may be, and the Administrative Agent after any such set-off and application made by such Lender; provided, that the failure to give such notice shall not affect the validity of such set-off and application.

14.9. Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the US Borrower and the Administrative Agent.

14.10. 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.

14.11. Integration. This Agreement and the other Credit Documents represent the agreement of the US Borrower, the UK Borrower, the Administrative Agent and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents.

14.12. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

14.13. Submission to Jurisdiction; Waivers. The US Borrower and the UK Borrower each hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Credit Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any

173

such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the US Borrower at its address set forth in Section 14.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 14.13 any special, exemplary, punitive or consequential damages.

14.14. Acknowledgments. The US Borrower and the UK Borrower each hereby acknowledge that:

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Credit Documents;

(b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to the US Borrower or the UK Borrower arising out of or in connection with this Agreement or any of the other Credit Documents, and the relationship between Administrative Agent and Lenders, on one hand, and the US Borrower or the UK Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Credit Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the US Borrower, the UK Borrower and the Lenders.

14.15. WAIVERS OF JURY TRIAL. THE US BORROWER, THE UK BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

14.16. Confidentiality. The Administrative Agent and each Lender shall hold all non-public information furnished by or on behalf of the US Borrower or the UK Borrower in connection with such Lender’s evaluation of whether to become a Lender hereunder or obtained by such Lender or the Administrative Agent pursuant to the requirements of this Agreement (“Confidential Information”), confidential in accordance with its customary procedure for handling confidential information of this nature and (in the case of a Lender that is a bank) in accordance with safe and sound banking practices

174

and in any event may make disclosure as required or requested by any governmental agency or representative thereof or pursuant to legal process or to such Lender’s or the Administrative Agent’s attorneys, professional advisors or independent auditors or Affiliates; provided, that unless specifically prohibited by applicable law or court order, each Lender and the Administrative Agent shall notify the US Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of such Lender by such governmental agency) for disclosure of any such non-public information prior to disclosure of such information; and provided further, that in no event shall any Lender or the Administrative Agent be obligated or required to return any materials furnished by the US Borrower or any Subsidiary of the US Borrower. Each Lender and the Administrative Agent agrees that it will not provide to prospective Transferees or to prospective direct or indirect contractual counterparties in swap agreements to be entered into in connection with Loans made hereunder any of the Confidential Information unless such Person shall have previously executed a Confidentiality Agreement in the form of Exhibit S.

14.17. Judgment Currency. (a) The obligations of the US Borrower and the UK Borrower hereunder and under the other Loan Documents to make payments in Dollars or in the Foreign Currencies, as the case may be (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 Administrative Agent or a Lender of the full amount of the Obligation Currency expressed to be payable to the Administrative Agent or Lender under this Agreement or the other Credit Documents. If, for the purpose of obtaining or enforcing judgment against the US Borrower, the UK Borrower or any other Credit Party 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, at the Dollar Equivalent of such amount, in each case, as of the date immediately preceding the day on which the judgment is given (such Business Day being hereinafter referred to as the “Judgment Currency Conversion Date”).

(b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, the US Borrower and the UK Borrower each covenant and agree to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date.

(c) For purposes of determining the Dollar Equivalent, such amounts shall include any premium and costs payable in connection with the purchase of the Obligation Currency.

175

14.18. Permitted Amendments. (a) The US Borrower may, by written notice to the Administrative Agent from time to time, make one or more offers to all Lenders holding Extended Revolving Credit Commitments to make one or more Permitted Amendments pursuant to procedures reasonably specified by the Administrative Agent and reasonably acceptable to the US Borrower. Such notice shall set forth (i) the terms and conditions of the requested Permitted Amendments and (ii) the date on which each such Permitted Amendment is requested to become effective (which shall not be less than 10 Business Days no more than 30 Business Days after the date of such notice). Only those Lenders holding Extended Revolving Credit Commitments that consent to such Permitted Amendment (“Accepting Lenders”) will have the maturity of their Extended Revolving Credit Commitments extended and be entitled to receive any increase in the Applicable ABR Margin or Applicable Eurodollar Margin and any fees, in each case, as provided therein.

(b) The US Borrower, the UK Borrower, Holdings and each Accepting Lender shall execute and deliver to the Administrative Agent such documentation as the Administrative Agent shall reasonably specify to evidence the acceptance of the Permitted Amendments and the terms and conditions thereof. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Permitted Amendment. Each of the parties hereto hereby agrees that, upon the effectiveness of any Permitted Amendment, the Agreement shall be deemed amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Permitted Amendment evidenced thereby and only with respect to the Loans and Commitments of the Accepting Lenders (including any amendments necessary to treat the Loans and Commitments of the Accepting Lenders in a manner consistent with the other Loans and Commitments under this Agreement). Notwithstanding the foregoing, no Permitted Amendment shall become effective under this Section 14.18 unless the Administrative Agent, to the extent so reasonably requested by the Administrative Agent, shall have received legal opinions, board resolutions and officer’s certificates consistent with those delivered on the Restatement Date.

14.19. Effect of the Amendment and Restatement. (a) On the Restatement Date, the Existing Credit Agreement shall be amended and restated in its entirety by this Agreement, and the Existing Credit Agreement shall thereafter be of no further force and effect and shall be deemed replaced and superseded in all respects by this Agreement, except to evidence (i) the incurrence by the Borrowers of the Obligations under and as defined in the Existing Credit Agreement (whether or not such Obligations are contingent as of the Restatement Date), (ii) the representations and warranties made by the Borrowers prior to the Restatement Date (which representations and warranties made prior to the Restatement Date shall not be superseded or rendered ineffective by this Agreement as they pertain to the period prior to the Restatement Date) and (iii) any action or omission performed or required to be performed pursuant to such Existing Credit Agreement prior to the Restatement Date (including any failure, prior to the Restatement Date, to comply with the covenants contained in Existing Credit Agreement). The parties hereto acknowledge and agree that (a) this Agreement and the other Credit Documents, whether executed and delivered in connection herewith or otherwise, do not constitute a novation or termination of the Obligations under the

176

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

Schedule 1.1(a)

Additional Cost Formulae

The Additional Cost is an addition to the interest rate 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 requirement of the European Central Bank.

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 Additional 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 Loan) and will be expressed as a percentage rate per annum.

The Additional Cost Rate for any Lender lending from a Facility 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 Loans made from that Facility Office) of complying with the minimum reserve requirements of the European Central Bank in respect of loans made from that Facility Office.

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

In relation to a Sterling Loan:

AB + C(B - D) + E x 0.01

Per cent. per annum

100 - (A + C)

in relation to a Loan in any currency other than Sterling:

E x 0.01

Per cent. per annum

300

Where:

A 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

[Signature Page to Amended and Restated Credit Agreement]

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 Foreign Currency Borrowing margin and the Additional Cost and, if the Loan is an overdue amount, the additional rate of interest specified in Section 2.8(c)) payable for the relevant Interest Period on the 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 Lender to the Administrative Agent pursuant to paragraph 7 below and expressed in pounds per ₤1,000,000.

For the purposes of this Schedule:

(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) “Facility Office” means the office or offices notified by a Lender to the Administrative Agent in writing on or before the date it becomes a Lender (or, following the date, by not less than five Business Days’ written notice) as the office or offices through which it will perform its obligations under this Agreement;

(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.I. Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fee 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; and

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

In application of the above formulae, A, B, C and D will be included in the formulae as percentages (i.e. 5 per cent. will be included in the formula as 5 and not as 0.05). A 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, the Reference Lender shall, as soon as practicable after publication by the Financial Services Authority, supply to the Administrative Agent, the rate of charge payable by the Reference Lender 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 the Reference Lender as being the average of the Fee Tariffs applicable to the Reference Lender for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of the Reference Lender.

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:

the jurisdiction of its Facility Office; and

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 the Reference Lender for the purposes 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 Facility Office in the same jurisdiction as its Facility Office.

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 including the Reference Lender pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects.

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

Any determination by the Administrative Agent pursuant to this Schedule in relation to a formula, the Additional 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 to this Agreement.

Each Guarantor further agrees to pay any and all expenses (including all fees and disbursements of counsel) that may be paid or incurred by the Administrative Agent or any other Secured Party in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, such Guarantor under this Guarantee.

Each Secured Party shall notify such Guarantor promptly of any such set -off and the appropriation and application made by such Secured Party, provided that the failure to give such notice shall not affect the validity of such set-off and application.

No Subrogation. Notwithstanding any payment or payments made by any of the Guarantors hereunder or any set-off or appropriation and application of funds of any of the Guarantors by the Administrative Agent or any other Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Party against the UK Borrower or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any other Secured Party for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the UK Borrower or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Administrative Agent and the other

Secured Parties by the Credit Parties on account of the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letters of Credit drawn by the UK Borrower shall be outstanding. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Administrative Agent and the other Secured Parties, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether due or to become due, in such order as the Administrative Agent may determine.

Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement or any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any Guarantor, the Administrative Agent may, but shall be under no obligation to, make a similar demand on the UK Borrower or any Guarantor or guarantor, and any failure by the Administrative Agent to make any such demand or to collect any payments from the UK Borrower or any Guarantor or guarantor or any release of the UK Borrower or any Guarantor or guarantor shall not relieve any Guarantor in respect of which a demand or

collection is not made or any Guarantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Guarantor. For the purposes hereof, “demand” shall include the commencement and continuance of any legal proceedings.

7. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, contraction, incurrence, renewal, extension, amendment, waiver or accrual of any of the Obligations, and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee, the Obligations or any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended, waived or accrued, in reliance upon this Guarantee; and all dealings between the UK Borrower and any of the Guarantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the UK Borrower or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee without regard to (a) the validity, regularity or enforceability of the Credit Agreement, any other Credit Document, any Letter of Credit or any Hedge Agreement, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Administrative Agent or any other Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to or be asserted by the UK Borrower against the Administrative Agent or any other Secured Party or (c) any other circumstance whatsoever (with or without notice to or knowledge of the UK Borrower or such Guarantor) that constitutes, or might be construed to constitute, an equitable or legal discharge, defence or limitation of the UK Borrower for the Obligations, or of such Guarantor under this Guarantee, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent or and any other Secured Party may, but shall be under no obligation to, pursue such rights and remedies as it may have against the UK Borrower or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any other Secured Party to pursue such other rights or remedies or to collect any payments from the UK Borrower or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the UK Borrower or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent and the other Secured Parties against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the other Secured Parties, and their respective successors, indorsees, transferees and

assigns, until all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit drawn by the UK Borrower shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. A Guarantor shall automatically be released from its obligations hereunder and the Guarantee of such Guarantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Guarantor ceases to be a Subsidiary of the US Borrower. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 7 shall be without recourse to or warranty by the Administrative Agent.

8. Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the UK Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the UK Borrower or any other Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

9. Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent in Dollars at the Administrative Agent’s Office, without set-off or counterclaim and without deduction for any taxes, levies, duties, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever (excluding taxes imposed on the net income or capital of the Administrative Agent and Secured Parties). If at any time any applicable law, regulation or international agreement requires any Guarantor to make any such deduction or withholding from any such payment, the sum due from such Guarantor with respect to such payment will be increased to the extent necessary to ensure that, after the making of such deduction or withholding, the Administrative Agent receives a net sum equal to the sum which it would have received had no deduction or withholding been required.

10. Representations and Warranties; Covenants.

Each Guarantor hereby represents and warrants that the representations and warranties set forth in Section 8 of the Credit Agreement as they relate to such Guarantor or in the other Credit Documents to which such Guarantor is a party, each of which is hereby incorporated herein by reference, are true and correct, and the Administrative Agent and each other Secured Party shall be entitled to rely on each of them as if they were fully set forth herein.

Each Guarantor hereby covenants and agrees with the Administrative Agent and each other Secured Party that, from and after the date of this Guarantee until the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letter of Credit drawn by the UK Borrower remains outstanding, such Guarantor shall take, or shall refrain from taking, as the case may be, all actions that are necessary to be taken or not taken so

that no violation of any provision, covenant or agreement contained in Section 9 or 10 of the Credit Agreement, and so that no Default or Event of Default, is caused by any act or failure to act of such Guarantor or any of its Subsidiaries.

11. Authority of Agent. Each Guarantor acknowledges that the rights andresponsibilities of the Administrative Agent under this Guarantee with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, right, request, judgment or other right or remedy provided for herein or resultingor arising out of this Guarantee shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and such Guarantor, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 14.2 of the Credit Agreement. All communications and notices hereunder to each Guarantor shall be given to it in care of the UK Borrower at the UK Borrower’s address set forth in Section 14.2 of the Credit Agreement.

A set of the copies of this Guarantee signed by all the parties shall be lodged with the Administrative Agent and the UK Borrower.

Severabilitv. Any provision of this Guarantee 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. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or enforceable provisions.

Integration. This Guarantee represents the agreement of each Guarantor and the Administrative Agent with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any other Secured Party relative to the subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents.

Amendments in Writing; No Waiver; Cumulative Remedies.

None of the terms or provisions of this Guarantee may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected

Guarantor(s) and the Administrative Agent in accordance with Section 14.1 of the Credit Agreement.

Neither the Administrative Agent nor any other Secured Party shall by any act
(except by a written instrument pursuant to Section 16(a) hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent or any Secured Party would otherwise have on any future occasion.

The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

Section Headings. The Section headings used in this Guarantee are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

The rights and obligations of each Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor as a party to this Guarantee.

WAIVER OF JURY TRIAL. EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS GUARANTEE, ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

The Administrative Agent shall have the right, at any time after the occurrence and during the continuance of an Event of Default and without notice to the Pledgor, to transfer to or to register in the name of the Administrative Agent or any of its nominees any or all of the Pledged Shares. Each delivery of Collateral (including any After-acquired Shares) shall be accompanied by a schedule describing the securities theretofore and then being pledged hereunder, which shall be attached hereto as Schedule 1 and made a part hereof, provided that the failure to attach any such schedule hereto shall not affect the validity of such pledge of such securities. Each schedule so delivered shall supersede any prior schedules so delivered.

5. Representations and Warranties. The Pledgor represents and warrants as follows:

(a) Schedule 1 hereto correctly represents as of the date hereof (i) the issuer of the Pledged Shares, the certificate number(s) evidencing the Pledged Shares, the Pledgor and the record and beneficial owner, the number and class and the percentage of the issued and outstanding Equity Interests of the issuer of such class of all Pledged Shares and (ii) together with the comparable schedule to each supplement hereto, includes all Equity Interests required to be pledged hereunder. The Pledged Shares represent 65% of the issued and outstanding Equity Interests of each class of Equity Interests in the issuer on the date hereof.

(b) The Pledgor is the legal and beneficial owner of the Collateral pledged to or assigned by the Pledgor hereunder free and clear of any Lien, except for the Lien created by this Pledge Agreement.

(c) As of the date of this Pledge Agreement, the Pledged Shares pledged by the Pledgor hereunder have been duly authorized and validly issued and, in the case of Pledged Shares issued by a corporation, are fully paid and non-assessable.

(d) The execution and delivery by the Pledgor of this Pledge Agreement and the pledge of the Collateral pledged by the Pledgor hereunder pursuant hereto create a valid and perfected first-priority security interest in the Collateral, securing the payment of the Obligations, in favor of the Administrative Agent for the ratable benefit of the Secured Parties.

(e) There is no existing agreement, option, right or privilege capable of becoming an agreement or option pursuant to which the Pledgor would be required to sell or otherwise dispose of any of the Pledged Shares.

6. Further Assurances. The Pledgor agrees that at any time and from time to time, at the expense of the Pledgor, it will execute any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements and other documents), which may be required under any applicable law, or which the Administrative Agent or the Required Lenders may reasonably request, in order (x) to perfect and protect any pledge, assignment or security interest granted or purported to be granted hereby (including the priority thereof) or (y) to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral.

7. Voting Rights; Dividends and Distributions; Etc. (a) So long as no Event of Default shall have occurred and be continuing:

(i) The Pledgor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Collateral or any part thereof for any purpose not prohibited by the terms of this Pledge Agreement or the other Credit Documents.

(ii) The Administrative Agent shall execute and deliver (or cause to be executed and delivered) to the Pledgor all such proxies and other instruments as the Pledgor may reasonably request for the purpose of enabling the Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above.

received in exchange for Pledged Shares or Pledged Debt or any part thereof, or in redemption thereof, or as a result of any merger, consolidation, amalgamation, acquisition, or other exchange of assets to which such issuer may be a party or otherwise, shall be, and shall be forthwith delivered to the Administrative Agent to hold as, Collateral and shall, if received by such Pledgor, be received in trust for the benefit of the Administrative Agent, be segregated from the other property or funds of such Pledgor and be forthwith delivered to the Administrative Agent as Collateral in the same form as so received (with any necessary indorsement).

(c) Upon written notice to the Pledgor by the Administrative Agent following theoccurrence and during the continuance of an Event of Default,

(i) all rights of the Pledgor to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 7(a)(i) shall cease, and all such rights shall thereupon become vested in the Administrative Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights during the continuance of such Event of Default, provided that, unless otherwise directed by the Required Lenders, the Administrative Agent shall have the right from time to time following the occurrence and during the continuance of an Event of Default to permit the Pledgor to exercise such rights.

(a) Such Grantor shall maintain the Security Interest created by this Security Agreement as a perfected Security Interest having at least the priority described in Section 3.2 and shall defend such Security Interest against the claims and demands of all Persons whomsoever (except for Liens permitted by the Credit Agreement, which Liens such Grantor shall pay and perform in accordance with their terms), in each case subject to Section 3.2(b).

(b) Such Grantor will furnish to the Administrative Agent and the Lenders from time to time statements and schedules further identifying and describing the assets and property of such Grantor and such other reports in connection therewith as the Administrative Agent may reasonably request. In addition, within 30 days after the end of each calendar quarter, such Grantor will deliver to the Administrative Agent a written supplement hereto substantially in the form of Annex 2 hereto with respect to any additional Copyrights, Copyright Licenses, Patents, Patent Licenses, Trademarks and Trademark Licenses acquired by such Grantor after the date hereof, all in reasonable detail.

(c) Subject to clause (d) below and Section 3.2(b), each Grantor agrees that at any time and from time to time, at the expense of such Grantor, it will execute any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, fixture filings, mortgages, deeds of trust and other documents), which may be required under any applicable law, or which the Administrative Agent or the Required Lenders may reasonably request, in order (x) to grant, preserve, protect and perfect the validity and priority of the Security Interests created or intended to be created hereby or (y) to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral, including the filing of any financing or continuation statements under the personal property security legislation of Canada in effect in any jurisdiction with respect to the Security Interests created hereby, all at the expense of such Grantor.

4.2 Changes in Locations, Name, etc. Each Grantor will furnish to the Administrative Agent prompt written notice of any change (i) in its legal name, (ii) in its jurisdiction of incorporation or organization, (iii) in the location of its chief executive office, its principal place of business, any office in which it maintains books or records relating to Collateral owned by it (including the establishment of any such new office), or (iv) in its identity or type of organization or corporate structure. Each Grantor agrees promptly to provide the Administrative Agent with certified organizational documents reflecting any of the changes described in the first sentence of this paragraph. Each Grantor agrees not to effect or permit any change referred to in the preceding sentence unless all filings have been made under applicable personal property security legislation or otherwise that are required in order for the Administrative Agent to continue at all times following such change to have a valid, legal and perfected security interest in all the Collateral having at least the priority described in Section 3.2. Each Grantor also agrees promptly to notify the Administrative Agent if any material portion of the Collateral is damaged or destroyed.

4.3 Notices. Each Grantor will advise the Administrative Agent and the Lenders promptly, in reasonable detail, of any Lien of which it has knowledge (other than the Security Interests created hereby or Liens permitted under the Credit Agreement ) on any of the Collateral which would adversely affect, in any material respect, the ability of the Administrative Agent to exercise any of its remedies hereunder.

5.1 Certain Matters Relating to Accounts.

(a) At any time after the occurrence and during the continuance of an Event of Default, the Administrative Agent shall have the right to make test verifications of the Accounts of each Grantor in any manner and through any medium that it reasonably considers advisable, and each Grantor shall furnish all such assistance and information as the Administrative Agent may require in connection with such test verifications. The Administrative Agent shall have the absolute right to share any information it gains from such inspection or verification with any Secured Party.

(b) The Administrative Agent hereby confirms each Grantor’s right to collect such Grantor’s Accounts, but the Administrative Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required in writing by the Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Accounts, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly endorsed by such Grantor to the Administrative Agent if requested, in a Collateral Account maintained under the sole dominion and control of and on terms and conditions reasonably satisfactory to the Administrative Agent, subject to withdrawal by the Administrative Agent for the account of the Secured Parties only as provided in Section 5.5, and (ii) until so turned over, shall be held by such Grantor in trust for the Administrative Agent and the Secured Parties, segregated from other funds of such Grantor. Each such deposit of Proceeds of Accounts shall be accompanied by a report of the applicable Grantor identifying in reasonable detail the nature and source of the payments included in the deposit.

(c) At the Administrative Agent’s request at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Administrative Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to such Grantor’s Accounts, including all original orders, invoices and shipping receipts.

(d) Upon the occurrence and during the continuance of an Event of Default, a Grantor shall not grant any extension of the time of payment of any of its Accounts, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any person liable for the payment thereof, or allow any credit or discount whatsoever thereon if the Administrative Agent shall have instructed the Grantors not to grant or make any such extension, credit, discount, compromise, or settlement under any circumstances during the continuance of such Event of Default.

5.2 Communications with Obligors; Grantors Remain Liable.

(a) The Administrative Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default, after giving reasonable notice to the relevant Grantor of its intent to do so, communicate with obligors under such Grantor’s Accounts to verify with them to the Administrative Agent’s satisfaction the existence, amount and terms of any of such Grantor’s Accounts. The Administrative Agent shall have the absolute right to share any information it gains from such inspection or verification with any Secured Party.

(b) Upon the written request of the Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on its Accounts that such Accounts have been assigned to the Administrative Agent for the ratable benefit of the Secured Parties and that payments in respect thereof shall be made directly to the Administrative Agent.

(c) Anything herein to the contrary notwithstanding, each Grantor shall, to the maximum extent provided by law, remain liable under each of its Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the Administrative Agent nor any Secured Party shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this Security Agreement or the receipt by the Administrative Agent or any Secured Party of any payment relating thereto, nor shall the Administrative Agent or any Secured Party be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

5.3 Proceeds to be Turned Over to Administrative Agent. In addition to the rights of the Administrative Agent and the Secured Parties specified in Section 5.1 with respect to payments of Accounts, if an Event of Default shall occur and be continuing and the Administrative Agent so requires by notice in writing to the relevant Grantor (it being understood that the exercise of remedies by the Secured Parties in connection with an Event of Default under Section 11.5 of the Credit Agreement shall be deemed to constitute a request by the Administrative Agent for the purposes of this sentence and in such circumstances, no such written notice shall be required), all Proceeds received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the Administrative Agent and the Secured Parties, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Administrative Agent in the exact form received by such Grantor (duly endorsed by such Grantor to the Administrative Agent, if requested by the Administrative Agent). All Proceeds received by the Administrative Agent hereunder shall be held by the Administrative Agent in a Collateral Account maintained under its sole dominion and control and on terms and conditions reasonably satisfactory to the Administrative Agent. All

Proceeds while held by the Administrative Agent in a Collateral Account (or by such Grantor in trust for the Administrative Agent and the Secured Parties) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 5.5.

5.4 Application of Proceeds. The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral as well as any Collateral consisting of cash, at any time after receipt as follows:

(i) first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Security Agreement, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of any Grantor and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

(ii) second, to the Secured Parties, an amount equal to all Obligations owing to them on the date of any distribution, and, if such moneys shall be insufficient to pay such amounts in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the unpaid amounts thereof; and

(iii) third, any surplus then remaining shall be paid to the Grantors or their successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

Upon any sale of the Collateral by the Administrative Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding) permitted hereunder, the receipt of the Administrative Agent or of the officer of the Administrative Agent making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Administrative Agent or such officer or be answerable in any way for the misapplication thereof.

5.5 Other Remedies. If an Event of Default shall occur and be continuing, the Administrative Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the Ontario PPSA or any other applicable law and also may without notice except as specified below, personally or by agent, at such time or times as the Administrative Agent in its discretion may determine, do any one or more of the following:

(b) Demand Possession.

(d) Deal with Collateral. Hold, store and keep idle, or operate, lease or otherwise use or permit the use of, any or all of the Collateral for such time and on such terms as the Administrative Agent may determine, and demand, collect and retain all earnings and other sums due or to become due from any Person in respect of any of the Collateral.

(e) Carry on Business. Carry on, or concur in the carrying on of, any or all of the business or undertaking of the Grantors and enter on, occupy and use (without charge by the Grantors) any of the premises, buildings, plant and undertaking of, or occupied or used by, the Grantors.

(f) Enforce Collateral. Seize, collect, receive, enforce or otherwise deal with any Collateral in such manner, on such terms and conditions and at such times as the Administrative Agent deems advisable.

(g) Dispose of Collateral. Realize on any or all of the Collateral and sell, lease, assign, give options to purchase, or otherwise dispose of and deliver any or all of the Collateral (or contract to do any of the above), in one or more parcels at any public or private sale, at any exchange, broker’s board or office of the Administrative Agent or elsewhere, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral, for cash or on credit or for future delivery.

(h) Court-Approved Disposition of Collateral. Apply to a court of competent jurisdiction for the sale or foreclosure of any or all of the Collateral.

(i) Purchase by Administrative Agent. At any public sale, and to the extent permitted by law on any private sale, bid for and purchase any or all of the Collateral offered for sale and, upon compliance with the terms of such sale, hold, retain and dispose of such Collateral without any further accountability to any Grantor or any other Person with respect to such holding, retention or disposition, except as required by applicable law. In any such sale to the Administrative Agent, the Administrative Agent may, for the purpose of making payment for all or any part of the Collateral so purchased, use any claim for Obligations then due and payable to it as a credit against the purchase price.

(k) Exercise of Rights. Exercise any and all rights, privileges, entitlements and options pertaining to any Investment Property forming part of the Collateral as if the Administrative Agent were the absolute owner of such Investment Property.

(1) Payment of Liabilities. Pay any liability secured by any Lien against any Collateral. Each Grantor will promptly on demand reimburse the Administrative Agent for all such payments.

(m) Borrow and Grant Security Interests. Borrow money for the maintenance, preservation or protection of any Collateral or for carrying on any of the business or undertaking of any Grantor and grant Security Interests on any Collateral (in priority to the Security Interests created by this Agreement or otherwise) as security for the money so borrowed. Each Grantor will promptly on demand reimburse the Administrative Agent for all such borrowings.

(n) Appoint Receiver. Appoint by instrument in writing one or more Receivers of any Grantor or any or all of the Collateral with such rights, powers and authority (including any or all of the rights, powers and authority of the Administrative Agent under this Agreement) as may be provided for in the instrument of appointment or any supplemental instrument, and remove and replace any such Receiver from time to time. To the extent permitted by applicable law, any Receiver appointed by the Administrative Agent will (for purposes relating to responsibility for the Receiver’s acts or omissions) be considered to be the agent of the Grantors and not of the Administrative Agent or the Secured Parties.

(o) Court-Appointed Receiver. Apply to a court of competent jurisdiction for the appointment of a Receiver of any Grantor or of any or all of the Collateral.

The Administrative Agent may exercise any or all of the foregoing rights and remedies without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except as required by applicable law) to or on the Grantors or any other Person, and the Grantors by this Agreement waive each such demand, presentment, protest, advertisement and notice to the extent permitted by applicable law. None of the above rights or remedies will be exclusive of or dependent on or merge in any other right or remedy, and one or more of such rights and remedies may be exercised independently or in combination from time to time. Without prejudice to the ability of the Administrative Agent to dispose of the Collateral at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral, each Grantor acknowledges that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. Each Grantor further acknowledges that a disposition of Collateral by the Administrative Agent which takes place substantially in accordance with the following provisions will be deemed to be commercially reasonable:

(i) Collateral may be disposed of in whole or in part;

(ii) Collateral may be disposed of by public auction, public tender or private contract, with or without advertising and without any other formality except as required by law;

(iii) any purchaser or lessee of Collateral may be a customer of the Administrative Agent;

(iv) a disposition of Collateral may be on such terms and conditions as to credit or otherwise as the Administrative Agent, in is sole discretion, may deem advantageous; and

(v) the Administrative Agent may establish an upset or reserve bid or price in respect of Collateral.

5.6 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the reasonable fees and disbursements of any attorneys employed by the Administrative Agent or any Secured Party to collect such deficiency.

5.7 Amendments, etc. with Respect to the Obligations; Waiver of Rights. Each Grantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Grantor and without notice to or further assent by any Grantor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement or documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Security Agreement or any property subject thereto. When making any demand hereunder against any Grantor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the US Borrower or any Grantor or grantor, and any failure by the Administrative Agent or any other Secured Party to make any such demand or to collect any payments from the US Borrower or

any Grantor or grantor or any release of the US Borrower or any Grantor or grantor shall not relieve any Grantor in respect of which a demand or collection is not made or any Grantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Grantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

(c) The expenses of the Administrative Agent incurred in connection with actions undertaken as provided in this Section 6.1, together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under the Credit Agreement, from the date of payment by the Administrative Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Administrative Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Security Agreement are coupled with an interest and are irrevocable until this Security Agreement is terminated and the Security Interests created hereby are released.

6.2 Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the Ontario PPSA or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account and as required by applicable law. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property and in accordance with applicable law. Neither the Administrative Agent, any Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Administrative Agent and the Secured Parties hereunder are solely to protect the Administrative Agent’s and the Secured Parties’ interests in the Collateral and shall not impose any duty upon the Administrative Agent or any Secured Party to exercise any such powers. The Administrative Agent and the Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

6.3 Authority of Administrative Agent. Each Grantor acknowledges that the rights and responsibilities of the Administrative Agent under this Security Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between the Administrative Agent and the Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the

Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

6.4 Security Interest Absolute. All rights of the Administrative Agent hereunder, the security interest and all obligations of the Grantors hereunder shall be absolute and unconditional.

6.5 Continuing Security Interest; Assignments Under the Credit Agreement; Release.

(a) This Security Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Grantor and the successors and assigns thereof and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their respective successors, indorsees, transferees and assigns until all Obligations under the Credit Documents and the obligations of each Grantor under this Security Agreement shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. This Security Agreement and the security interest granted hereby shall terminate on the first date on which all of the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding.

(b) A Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Grantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Grantor ceases to be a Subsidiary of the US Borrower.

(c) Upon any sale or other transfer by any Grantor of any Collateral that is permitted under the Credit Agreement, or upon the effectiveness of any written consent to the release of the Security Interest granted hereby in any Collateral pursuant to Section 14.1 of the Credit Agreement, the Security Interest in such Collateral shall be automatically released and such Collateral sold free and clear of the Lien and Security Interests created hereby.

(d) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Administrative Agent shall execute and deliver to any Grantor, at such Grantor’s expense, all documents that such Grantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 6.5 shall be without recourse to or warranty by the Administrative Agent.

6.6 Reinstatement. This Security Agreement shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the US Borrower or any other Credit Party, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the US Borrower or any

other Credit Party or any substantial part of its property, or otherwise, all as though such payments had not been made.

7. Administrative Agent As Agent.

(a) Credit Suisse First Boston, acting through its Cayman Islands Branch, has been appointed to act as Administrative Agent hereunder by the Lenders and, by their acceptance of the benefits hereof, the other Secured Parties. The Administrative Agent shall be obligated, and shall have the right hereunder, to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking any action (including the release or substitution of Collateral), solely in accordance with this Security Agreement and the Credit Agreement, provided that the Administrative Agent shall exercise, or refrain from exercising, any remedies provided for in Section 5 in accordance with the instructions of (i) Required Lenders or (ii) after the termination of this Security Agreement. In furtherance of the foregoing provisions of this Section 7(a), each Secured Party, by its acceptance of the benefits hereof, agrees that it shall have no right individually to realize upon any of the Collateral hereunder, it being understood and agreed by such Secured Party that all rights and remedies hereunder may be exercised solely by the Administrative Agent for the ratable benefit of the Lenders and Secured Parties in accordance with the terms of this Section 7(a).

(b) The Administrative Agent shall at all times be the same Person that is the Administrative Agent under the Credit Agreement. Written notice of resignation by the Administrative Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute notice of resignation as Administrative Agent under this Security Agreement; removal of the Administrative Agent shall also constitute removal as Administrative Agent under this Security Agreement; and appointment of a successor Administrative Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute appointment of a successor Administrative Agent under this Security Agreement. Upon the acceptance of any appointment as Administrative Agent under Section 12.9 of the Credit Agreement by a successor Administrative Agent, that successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Administrative Agent under this Security Agreement, and the retiring or removed Administrative Agent under this Security Agreement shall promptly (i) transfer to such successor Administrative Agent all sums, securities and other items of Collateral held hereunder, together with all records and other documents necessary or appropriate in connection with the performance of the duties of the successor Administrative Agent under this Security Agreement, and (ii) execute and deliver to such successor Administrative Agent such amendments to financing statements and take such other actions, as may be necessary or appropriate in connection with the assignment to such successor Administrative Agent of the Security Interests created hereunder, whereupon such retiring or removed Administrative Agent shall be discharged from its duties and obligations under this Security Agreement. After any retiring or removed Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Security Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it under this Security Agreement while it was Administrative Agent hereunder.

(c) The Administrative Agent shall not be deemed to have any duty whatsoever with respect to any Secured Party that is a counterparty to a Hedge Agreement the obligations under

which constitute Obligations, until it shall have received written notice in form and substance satisfactory to the Administrative Agent from a Grantor or any such Secured Party as to the existence and terms of the applicable Hedge Agreement.

8. Miscellaneous.

8.1 Amendments in Writing. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected Grantor and the Administrative Agent in accordance with Section 14.1 of the Credit Agreement.

8.3 No Waiver by Course of Conduct; Cumulative Remedies.

No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent or such other Secured Party would otherwise have on any future occasion. The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

8.4 Enforcement Expenses; Indemnification.

(a) Each Grantor agrees to pay any and all expenses (including all reasonable fees and disbursements of counsel) that may be paid or incurred by any Secured Party in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, such Grantor under this Security Agreement.

(b) Each Grantor agrees to pay, and to save the Administrative Agent and the Secured Parties harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes (excluding taxes imposed on the net income or capital of the Administrative Agent and Secured Parties) which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Security Agreement.

(d) The agreements in this Section 8.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Credit Documents.

8.5 Successors and Assigns. The provisions of this Security Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that no Grantor may assign, transfer or delegate any of its rights or obligations under this Security Agreement without the prior written consent of the Administrative Agent except pursuant to a transaction permitted by the Credit Agreement.

8.6 Counterparts. This Security Agreement may be executed by one or more of the parties to this Security Agreement on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Security Agreement signed by all the parties shall be lodged with the Administrative Agent and the US Borrower.

8.7 Severability. Any provision of this Security 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. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

8.8 Section Headings. The Section headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

g) The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms.

2. Grant of Security. The Pledgor hereby undertakes in accordance with Section 4 to pledge to the Secured Parties, for their ratable benefit, represented by the Administrative Agent, all of the Pledgor’s right, title and interest in the following, now owned or existing, and hereby undertakes to pledge to the Secured Parties represented by the Administrative Agent all of the Pledgor’s right, title and interest in any of the following hereafter acquired or existing (collectively, the “Collateral”):

a) the Pledged Shares registered in the Pledgor’s name in an account held by the Company (the “Pledged Account”) and, subject to Section 7 hereof, all dividends, cash, warrants, rights, instruments and other property or proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the Pledged Shares, provided that the Pledged Shares under this Pledge Agreement shall not include more than 65 percent of each issued and outstanding Class of Equity Interests in the Company.

3. Security for Obligations. This Pledge Agreement secures the payment of all Obligations owed by the Borrowers and/or each other Credit Party to the Administrative Agent or the Secured Parties for their ratable benefit. Without limiting the generality of the foregoing, this Pledge Agreement secures the payment of all amounts that constitute part of the Obligations and would be owed by the Borrowers to the Administrative Agent or the Secured Parties under the Credit Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrowers and/or each other Credit Party.

4. Perfection of Security. Subject to the prior Lien registered on the Pledged Shares being released, which release shall occur no later than July 31, 2004, the pledge of the Pledged Shares shall be constituted pursuant to article L 431-4 of the French Monetary and Financial Code by the execution of a declaration of pledge of the Pledged Account (déclaration de gage de compte d’instruments financiers, hereinafter the “Déclaration de Gage”) in the form set forth in Annex 1 hereto, which shall occur at the latest on August 2, 2004. The Pledgor hereby undertakes to cause the Company to issue at the latest on August 2, 2004 a certificate of confirmation of pledge relating to the Pledged Account (attestation de gage) in the form of Annex 2 hereto, and promptly to transmit such confirmation of pledge to the Administrative Agent.

5. Representations and Warranties. The Pledgor represents and warrants as follows:

a) Schedule 1 hereto (i) correctly represents as of the date hereof the issuer, the Pledgor, the number, the Class of Equity Interest and the percentage of the issued and outstanding Class of Equity Interests of such Class of Equity Interests of all Pledged Shares and (ii) includes all Equity Interests required to be pledged hereunder. Except as set forth on Schedule 1, the Pledged Shares represent 65 percent of such issued and outstanding Class of Equity Interests and no other Class of Equity Interests in the Company has been issued on the date hereof.

b) On the date hereof, the Pledgor is the owner of the Pledged Shares and, as from the execution of the Déclaration de Gage referred to in Section 4 above, the Pledgor shall be the owner of the Collateral pledged by the Pledgor hereunder free and clear of any Lien, except for the Lien created by this Pledge Agreement and the Déclaration de Gage referred to in Section 4 above.

c) As of the date of this Pledge Agreement, the Pledged Shares pledged by the Pledgor hereunder have been duly authorized by a meeting of the shareholders of the Company and are validly issued and are fully paid up.

d) The execution and delivery by the Pledgor of the Déclaration de Gage pursuant to this Pledge Agreement and the pledge of the Collateral by the Pledgor thereunder shall immediately create a valid and perfected first-priority security interest in the Collateral, securing the payment of the Obligations, in favor of the Secured Parties.

e) The Pledgor has full power, authority and legal right to pledge all the Collateral in accordance with this Pledge Agreement and this Pledge Agreement constitutes a legal, valid and binding obligation of the Pledgor, enforceable in accordance with its terms, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditor’s rights generally.

f) With the exception of the authorization procedure provide for in Article 7 of the Company’s by-laws (statuts), there is no provision in the by-laws of the Company or any other instrument which would restrict the exercise by the Administrative Agent of its rights under this Pledge Agreement or the Declaration de Gage.

6. Further Assurances. The Pledgor agrees that at any time and from time to time, at the expense of the Pledgor, it will execute any and all further documents, agreements and instruments and take all such further actions, which may be required under any applicable law, or which the Administrative Agent or the Required Lenders may reasonably request, in order (x) to perfect and protect any pledge, assignment or security interest granted or purported to be granted hereby (including the priority thereof) or (y) to enable the Administrative Agent to exercise and enforce the rights and remedies hereunder with respect to any Collateral.

7. Voting Rights; Dividends and Distributions; Etc.

a) Subject to paragraph (b) below, the Pledgor shall be entitled to receive and retain and use, free and clear of the Lien of this Pledge Agreement, any and all dividends and distributions made or paid in respect of the Collateral to the extent permitted by the Credit Agreeement; provided, however, that any and all noncash dividends or other distributions that would constitute Pledged Shares, whether resulting from a subdivision, combination or reclassification of the outstanding Equity Interests of the issuer of any Pledged Shares or received in exchange for Pledged Shares or any par thereof, or in redemption thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which such issuer may be a party or otherwise, shall be deposited in the Pledged Account and shall be held as Collateral and shall, if received by the Pledgor, be held for the benefit of the Administrative Agent, be segregated from the other property or funds of the Pledgor and be forthwith deposited in the Pledged Account as Collateral in the same form as so received.

b) Upon written notice to the Pledgor by the Administrative Agent following the occurrence and during the continuance of an Event of Default,

(i) all rights of the Pledgor to receive the dividends and distributions that the Pledgor would otherwise be authorized to receive and retain pursuant to Section 7 (a) shall cease, and all such rights shall thereupon become vested in the Administrative Agent as agent for the Secured Parties, which shall thereupon have the sole right to receive and hold as Collateral such dividends and distributions during the continuance of such Event of Default. The Administrative Agent shall retain those amounts as a “gage espèce”. After all Events of Default have been cured or waived and the Pledgor has delivered to the Administrative Agent a certificate to that effect, the Administrative Agent shall repay to the Pledgor (without interest) all such dividends and distributions that the Pledgor would otherwise be permitted to receive, retain and use pursuant to the terms of Section 7 (a);

(ii) all dividends and distributions that are received by the Pledgor contrary to the provisions of Section 7 (a) and 7 (b)(i) shall be held for the benefit of the Administrative Agent, shall be segregated from other property or funds of the Pledgor and shall forthwith be deposited in the Pledged Account or, in the case of cash dividends, distributions of cash or any other distributions which may not by its nature be registered on the Pledged Account, shall be transferred to the Administrative Agent which shall retain the same as “gage-espèce” or as a “gage”;

c) The Pledgor agrees as of the date hereof and as long as the Pledge Agreement remains in force:

(i) to refrain from using any voting rights in respect of the Pledged Shares and any other financial instruments subsequently registered on the Pledged Account in a way which would be contrary to the provisions of this Pledge Agreement or of any other Credit Document to which the Pledgor is a party;

(ii) (x) if the Company proceeds with a reduction of share capital which is not motived by losses, not to offer the shares of the Company that it owns to the Company for repurchase and (y) if the Company proceeds with a share capital reduction which is motivated by losses, to inform the Administrative Agent of the proposed reduction before its adoption by the shareholders’ meeting and to cause any new shares issued and attributed to the Pledgor as a result of the reduction in capital to be included in the Collateral; and

(iii) with the exception of the authorization procedure provided for in Article 7 of the Company’s by-laws, not to permit the Company’s by-laws or any other instrument to contain any provision (including preemption rights, rights of replacement or similar rights) which would limit in any way the execution or the performance of this Pledge Agreement or the enforcement by the Administrative Agent of the security interest herein created.

8. Transfers and Other Liens. The Pledgor shall:

a) not (i) except as permitted by the Credit Agreement, sell or otherwise dispose of, or grant any option or warrant with respect to, any of the Collateral or (ii) create or suffer to exist any contractual Lien upon or with respect to any of the Collateral, except for the

Lien under this Pledge Agreement and the related Déclaration de Gage, provided that in the event the Pledgor sells or otherwise disposes of assets permitted by the Credit Agreement and such assets are or include any of the Collateral, the Administrative Agent shall release such Collateral to the Pledgor free and clear of the Lien under this Pledge Agreement and the related Déclaration de Gage concurrently with the consummation of such sale;

b) defend its and the Administrative Agent’s title or interest in and to all the Collateral (and in the proceeds thereof) against any and all Liens (other than the Lien of this Pledge Agreement), however arising, and any and all Persons whomsoever.

9. Remedies. If any Event of Default shall have occurred and be continuing:

a) The Administrative Agent and any nominee of the Administrative Agent may on behalf of the Secured Parties exercise in respect of all or any of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies conferred on a secured creditor (créancier gagiste) pursuant to French law and regulations, and may, subject to the prior authorization of the Company’s Board of Directors pursuant to Section 7 of the Company’s by-laws and to the prior information and consultation of the Company’s Workers Council (Comité d’entreprise) as required by article L.432-1 of the French Code du travail, (x) proceed to a public sale of the Collateral in accordance with the provisions of Article L.521-3 of the French Commercial Code, or (y) petition a French court to attribute ownership of the Collateral to the Secured Parties.

In the event ownership of the Collateral is attributed to the Secured Parties pursuant to clause (y) above, subject to mandatory provisions of French law and except as specified below, the Administrative Agent acting in such capacity:

(i) shall be entitled to sell the Collateral or any part thereof in one or more parcels for cash, on credit or for future delivery, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral;

(ii) shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Administrative Agent shall have, subject to the aforementioned restrictions, the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted; and

(iii) The Administrative Agent or any Secured Party shall have the right, to the extent permitted by law, upon any such sale, to purchase the whole or any part of the Collateral so sold.

The Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to the Pledgor shall constitute sufficient notification. Subject to applicable law, the Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, the Pledgor hereby waives any claim against the Administrative Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Administrative Agent accepts the first offer received and does not offer such Collateral to more than one offeree.

b) The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral (except, for the avoidance of doubt, in the case of a sale following the attribution of ownership of the same as referred to in Section 9(a)(y)) at any time after receipt as follows:

(i) first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Pledge Agreeement, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of the Pledgor and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

(ii) second, to the Secured Parties, an amount equal to all Obligations owing to them on the date of any such distribution, and, if such moneys shall be insufficient to pay such amounts in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the unpaid amounts thereof; and

(iii) third, any surplus then remaining shall be paid to the Pledgor or its successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

Upon any sale of the Collateral by the Administrative Agent following attribution of ownership of the Collateral to the Secured Parties by a French court pursuant to Section 9(a)(y) above, such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Administrative Agent or such officer or be answerable in any way for the misapplication thereof.

c) All payments received by the Pledgor after the occurrence and during the continuance of an Event of Default in respect of the Collateral shall be held for the

benefit of the Administrative Agent, shall be segregated from other property or funds of the Pledgor and shall be forthwith delivered to the Administrative Agent as Collateral (“ gage-espèce”) in the same form as so received.

d) The Pledgor hereby waives its rights under Articles 2032 and 2039 of the French Civil Code.

10. Amendments, etc. with Respect to the Obligations; Waiver of Rights. The Pledgor shall remain obligated hereunder, and the charges created hereby shall not be adversely affected nor shall this Agreement be novated unless expressly agreed in writing by the parties hereto, notwithstanding that, without any reservation of rights against the Pledgor and without notice to or further assent by the Pledgor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon of for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement, or document entered into with the Administrative Agent or any of its affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure perfect or insure any Lien at any time held by it as security for the Obligations or for this Pledge Agreement or any property subject thereto. When making any demand hereunder against the Pledgor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the Borrowers or any pledgor and any failure by the Administrative Agent or any other such Secured Party to make any such demand or to collect any payments from the Borrowers or any pledgor or any release of the Borrowers or any pledgor shall not relieve the Pledgor in respect of which a demand or collection is not made or the Pledgor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against the Pledgor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

11. Continuing Security Interest; Assignments Under the Credit Agreement: Release.

a) This Pledge Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon the Pledgor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their respective successors, indorsees, transferees and assigns until all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations.

b) Upon any sale or other transfer by the Pledgor of any Collateral that is permitted under the Credit Agreement to any Person, or upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 14.1 of the Credit Agreement, the obligations of such Pledgor with respect to such Collateral shall be automatically released and such Collateral sold free and clear of the Lien created hereby.

c) In connection with any termination or release pursuant to paragraph (a) or (b), the Administrative Agent shall execute and deliver to the Pledgor, at the Pledgor’s expense, all documents that the Pledgor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 11 shall be without recourse to or warranty by the Administrative Agent.

12. Reinstatement. This Pledge Agreement shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, administration, liquidation or reorganization of the Pledgor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Pledgor or any substantial part of its property, or otherwise, all as though such payments had not been made.

13. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 14.2 of the Credit Agreement.

14. Severability. Any provision of this Pledge 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 invalidate or render unenforceable such provision in any other jurisdiction. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

15. Integration. This pledge Agreement and the Schedule and Annexes hereto represent the agreement of the Pledgor with respect to the subject matter hereof and there are no promises, undertakings, representations or warranties by the Administrative Agent or

10.8 The Security Recipient agrees to release proceeds from the enforcement of any of the Collateral if and to the extent that:

10.8.1 the Collateral secures claims against shareholders of any Security Provider or persons deemed to be equivalent to shareholders for purposes of Sections 30 and 31 of the

German Limited Liability Companies Act (GmbHG) (Gesellschaft nahestehende Personen),

10.8.2 in relation to each Security Provider, the Security Provide demonstrates to the satisfaction of the Security Recipient that the application of proceeds towards such claims would lead to a situation that such Security Provider would not have sufficient assets to maintain its nominal capital (Stammkapital), and

10.8.3 the Security Provider demonstrates to the satisfaction of the Security Recipient that the application of the proceeds therefore would lead to a violation of Section 30 of the German Limited Liability Companies Act (GmbHG), provided that for the purposes of the calculation of the amount to be released (if any) the following balance sheet items shall be adjusted as follows:

10.8.4 the amount of any increase of nominal capital (Stammkapital) after the date hereof that has been effected without prior written consent of the Security Recipient shall be deducted from the nominal capital (Stammkapital), and

10.8.5 loans and other contractual liabilities incurred in violation of the provisions of the Credit Agreement shall be disregarded.

For the avoidance of doubt, each Security Provider shall have a right to the proceeds to the extent such proceeds have to be released. However, no release under this clause will prejudice the rights of the Security Recipient to enforce the Collateral again.

10.9 In addition, if any Security Provider does not (or would not if the Collateral is enforced) have sufficient assets to maintain its nominal capital, such Security Provider shall to the extent legally permitted in respect of its business realise any and all of its assets that are shown in its balance sheet with a book value (Buchwert) that is significantly lower than the market value of the asset(s) if such asset(s) is/are not necessary for such Security Provider’s business (betriebsnotwendig).

11 Information obligation in the event of impairments of the Collateral

11.1 Each Security Provider undertakes to inform the Security Recipient without undue delay of any impairments of the Collateral (or any part thereof), in particular but not limited to set-off, price discounts, third party debtor complaints or any other event having an adverse effect on the actual value of the Collateral. The same shall apply to changes of the maturity of the Assigned Claims or if a Security Provider becomes aware of any circumstances that may affect the solvency of any third party debtor. If any of Assigned Claims are attached (gepfändet), the Security Providers shall without undue delay inform the Security Recipient accordingly and send to the Security Recipient a copy of the order of attachment and transfer. The Security Providers shall further inform the attaching creditor in writing of the Security Recipient’s security interest in the Assigned Claims.

11.2 In each of the events described in clause 11.1 above, the Security Providers shall act according to the Security Recipient’s instructions.

12 Right of survey and inspection

12.1 Each Security Provider shall give the Security Recipient, upon request, all information, evidence, and documents which in the Security Recipient’s reasonable opinion are necessary for the evaluation and/or assertion of the Assigned Claims. If electronic data processing facilities are used, each Security Provider must print the necessary documents; if no printout is made, the data carriers and the software necessary for this shall be delivered to the Security Recipient to enable it to make the printout itself.

12.2 The Security Recipient shall have the right to inspect either by itself or through its nominated and duly authorized agent each Security Provider’s documents for purposes of inspecting and realizing the Collateral.

12.3 The Security Recipient shall have the absolute right to share any information it gains from such inspection or verification or otherwise in connection with this Agreement with any Secured Party.

13 Security value and release of Collateral

13.1 After the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letters of Credit drawn by the UK Borrower shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations (the “Discharge Date”), the Security Recipient shall retransfer to each Security Provider all Collateral assigned and transferred to it hereunder by each Security Provider and surrender any excess proceeds to the Security Providers, at the Security Providers’ expense. However, the Security Recipient will transfer such Collateral to a third party if it is obliged to do so; that is the case, for example, if a Security Provider is at the same time a debtor, and a surety has made payment to the Security Recipient.

13.2 The Security Recipient is obliged, already prior to the full discharge of the Secured Claims and the termination of any facilities which may give rise to the Secured Claims, to entirely or partially release the Collateral, if so requested, to a Security Provider, provided and to the extent that the realisable value of all security provided to secure the Secured Claims not only temporarily exceeds 110 percent of the Secured Claims. To the extent the Security Recipient is obliged to pay any taxes in connection with the realisation of the Collateral, in particular, but not limited to VAT (Umsatzsteuer), the aforementioned percentage shall be increased by the applicable tax rate(s).

13.3 The Security Recipient shall be free to select the security items to be released under clause 13.1 above and, to the extent an obligation of the Security Recipient to release any security provided for the Secured Claims (or any part thereof) also exists under or in connection with any other security agreement, under any other security document. In selecting security items to be released under clause 13.2 above, the Security Recipient shall duly consider the Security Providers’ legitimate interests and the legitimate interests of parties having provided additional security.

13.4 A Security Provider shall automatically be released from its obligations hereunder and the assignment of such Security Provider shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Security Provider ceases to be a Subsidiary of the US Borrower. In connection with any such release, the Security Recipient shall execute and deliver to the relevant Security Provider, at such Security Provider’s expense, all documents that such Security Provider shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this clause 13.4 shall be without recourse to or warranty by the Security Recipient.

14 Authority of Agent

The Security Providers acknowledge that the rights and responsibilities of the Security Recipient under this Agreement with respect to any action taken by the Security Recipient or the exercise or non-exercise by the Security Recipient of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Security Recipient and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Security Recipient and the Security Providers, the Security Recipient shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and the Security Providers shall not have the obligation, or entitlement, to make any inquiry respecting such authority.

15 Further assurance

Each Security Provider will execute any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, mortgages, deeds of trust and other documents), which may be required under any applicable law, or which the Security Recipient or the Required Lenders may reasonably request, in order to effectuate the transactions contemplated by this Agreement and in order (x) to grant, preserve, protect and perfect the validity and priority of the security interests created or intended to be created hereby or (y) to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral, all at the expense of such Security Provider.

16 Assignment and transfer

16.1 The Security Recipient shall, at any time, have the right to assign, to transfer, or to dispose of all or any part of its rights or obligations or both under this Agreement to any of the Secured Parties or any person becoming a Secured Party and each Security Provider shall execute all such documents and do all such acts and things which the Security Recipient may reasonably require in connection with such transfer, assignment, or disposal.

16.2 No Security Provider shall be entitled to assign, to transfer or to dispose of all or any part of its rights or obligations or both hereunder.

16.3 Each Security Provider hereby agrees to any accession of a new party and any change to the parties to the Credit Documents and the Hedge Agreements. Each Security Provider further agrees to that, notwithstanding any such accession of a party or change to the parties, to the Credit Documents or any assignment, transfer or disposal as contemplated in clause 16.1 above, this Agreement shall remain in full force and effect.

17 Costs and expenses

All reasonable costs and expenses arising from the execution of this Agreement, from amendments or prolongation thereof or any costs arising from the enforcement or preservation of the Security Recipient’s rights hereunder shall be borne jointly and severally by the Security Providers, whereby the Security Recipient is entitled to mandate a third party to perform such actions in its own name but for each Security Provider’s account.

18 Indemnity

18.1 The Security Recipient shall not be liable for any loss or damage which is suffered by a Security Provider save in respect of such loss or damage which is suffered as a result of the Security Recipient’s willful misconduct (Vorsatz) or gross negligence (grobe Fahrlässigkeit).

18.2 The Security Providers shall jointly and severally indemnify the Security Recipient and keep the Security Recipient indemnified against any losses, actions claims, expenses, demands and liabilities which may be made against or incurred by the Security Recipient for anything done or omitted in the exercise or purported exercise of the powers and rights under this Agreement or occasioned by any breach of a Security Provider of any of its obligations or undertakings under-contained herein, provided always that there will be no such indemnification, to the extent that such losses, actions, claims, expenses, demands and liabilities are incurred by or made against the Security Recipient as a result of willful misconduct or gross negligence of the Security Recipient.

19 Duration and partial invalidity

19.1 This Agreement shall remain in full force and effect until the Discharge Date. As long as the Obligations under the Credit Documents remain outstanding no Security Provider shall assert any claims against the UK Borrower or any Credit Party that is a Foreign Subsidiary (or any of them) which might arise from the fulfillment of its obligations according to this Agreement, either contractual or statutory. The monies which are transferred to or debited by a Security Provider from the UK Borrower or any Credit Party that is a Foreign Subsidiary (or any of them) shall be received by such Security Provider on trust (treuhänderisch) and transferred by it on trust to the Security Recipient. When payments are made to the Security Recipient by a Security Provider, such Security Provider shall not assert any rights or claims against the debtors arising by virtue of such payment until the Secured Claims have been paid and discharged in full and any facilities which may give rise to the Secured Claims have been terminated.

19.2 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.

19.3 In case of a prohibited, invalid or unenforceable provision the parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions..

19.4 This Agreement shall create a continuing security and no change or amendment to the Credit Documents shall affect the validity and the scope of this Agreement nor the obligations which are imposed on the Security Providers pursuant to it.

19.5 Subject to anything expressed to the contrary in this Agreement, this Agreement is independent from any other security or guarantee which may have been given to the Secured Parties with respect to any of the Secured Claims. None of such other security interests shall prejudice, or shall be prejudiced by, or shall be merged in any way with, this Agreement.

19.6 This Agreement shall inure to the benefit of the Security Recipient, its successors and assigns.

5.2 Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of clause 14 hereof. The provisions of this clause 5 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent and the other Secured Parties, and each Guarantor shall remain liable to the Administrative Agent and the other Secured Parties for the full amount guaranteed by such Guarantor hereunder.

5.3 In addition to any rights and remedies of the Secured Parties provided by law, each Guarantor hereby irrevocably authorizes each Secured Party at any time and from time to time following the occurrence and during the continuance of an Event of Default without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each Guarantor, upon any amount becoming due and payable by such Guarantor hereunder (whether at stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time

or demand, provisional or final), and any other credits, indebtedness or claims, in each case whether direct or indirect, absolute or contingent, at any time held or owing by such Secured Party to or for the credit or the account of such Guarantor. Each Secured Party shall notify such Guarantor promptly of any such set-off and the appropriation and application made by such Secured Party, provided that the failure to give such notice shall not affect the validity of such set-off and application.

6 Limitation of Guarantee

6.1 The Administrative Agent agrees to release proceeds from the enforcement of any collateral established by this Guarantee if and to the extent that:

6.1.1 the collateral secures claims against shareholders of any Guarantor or Persons deemed to be equivalent to shareholders for purposes of Sections 30 and 31 of the German Limited Liability Companies Act (GmbHG) (Gesellschaft nahestehende Personen),

6.1.2 in relation to each Guarantor, the application of proceeds towards such claims would lead to a situation that such Guarantor would not have sufficient assets to maintain its nominal capital (Stammkapital), and

6.1.3 the relevant Guarantor demonstrates to the satisfaction of the Administrative Agent that the application of the proceeds therefore would lead to a violation of Section 30 of the German Limited Liability Companies Act (GmbHG),

provided that for the purposes of the calculation of the amount to be released (if any) the following balance sheet items shall be adjusted as follows:

6.1.4 the amount of any increase of nominal capital (Stammkapital) after the date hereof that has been effected without prior written consent of the recipient of the Guarantee shall be deducted from the nominal capital (Stammkapital), and

6.1.5 loans and other contractual liabilities incurred in violation of the provisions of the Credit Agreement shall be disregarded.

For the avoidance of doubt, each Guarantor shall have a right to the proceeds to the extent such proceeds have to be released. No release under this clause will prejudice the rights of the Administrative Agent to claim again under this Guarantee for any unpaid amount.

6.2 In addition, if any Guarantor does not (or would not if the Guarantee is enforced) have sufficient assets to maintain its nominal capital, such Guarantor shall to the extent legally permitted in respect of its business realize any and all of its assets that are shown in its balance sheet with a book value (Buchwert) that is significantly lower than the market value of the asset(s) if such asset(s) is/are not necessary for such Guarantor’s business (betriebsnotwendig).

7 Payments, Currency and currency indemnity

All payments to be made by a Guarantor under this Guarantee shall be made to the Administrative Agent in United States Dollars (hereinafter referred to as “Contractual Currency”) at the Administrative Agent’s Office. In the event of the Administrative Agent recovering any amount hereunder in a currency other than the Contractual Currency and if the said amount so recovered is insufficient when converted into Contractual Currency at the date of receipt by the Administrative Agent to satisfy in full the amount due to the Administrative Agent hereunder, each Guarantor shall upon the Administrative Agents written demand pay to the Administrative Agent such further amount(s) in the Contractual Currency as will be sufficient to satisfy in full the amount so due to the Administrative Agent hereunder and such further amount(s) shall be due as a separate debt hereunder.

8 Several Guarantors

The obligations and liabilities of the Guarantors under this Guarantee are joint and several and shall be construed accordingly.

9 Declaration of trust

Each of the Guarantors and the Administrative Agent acknowledges that all rights and claims constituted by this Guarantee and all rights, claims, and moneys paid to the Administrative Agent or held by the Administrative Agent pursuant to or in connection with this Guarantee are held and administered by the Administrative Agent with effect from the date of this Guarantee on trust (treuhänderisch) for the Secured Parties and administered in accordance with the Credit Agreement.

10 Application of proceeds

The Administrative Agent shall apply, vis-à-vis the Secured Parties, the proceeds of any payment of the Guarantors after receipt as follows:

first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such payment or otherwise in connection with this Agreement, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of the Guarantors and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

second, to the Secured Parties, an amount equal to all Obligations owing to them on the date of any such distribution, and, if such moneys shall be insufficient to pay such amounts in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the unpaid amounts thereof;

third, any surplus then remaining shall be paid to the relevant Guarantors or its successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

11.5 that the representations and warranties set forth in Section 8 of the Credit Agreement as they relate to such Guarantor or in the other Credit Documents to which such Guarantor is a party, each of which is hereby incorporated herein by reference, are true and correct, and the Administrative Agent and each other Secured Party shall be entitled to rely on each of them as if they were fully set forth herein.

accrual of any of the Obligations, and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee, the Obligations or any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended, waived or accrued, in reliance upon this Guarantee; and all dealings between the Borrowers and any of the Guarantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Borrowers or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, regularity or enforceability of the Credit Agreement, any other Credit Document, any Letter of Credit or any Hedge Agreement, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Administrative Agent or any other Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to or be asserted by the Borrowers against the Administrative Agent or any other Secured Party or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Borrowers or such Guarantor) that constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrowers for the Obligations, or of such Guarantor under this Guarantee, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent and any other Secured Party may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Borrowers or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any other Secured Party to pursue such other rights or remedies or to collect any payments from the Borrowers or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Borrowers or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent and the other Secured Parties against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the other Secured Parties, and their respective successors, indorsees, transferees and assigns, until all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. A Guarantor shall automatically be released from its obligations hereunder and the Guarantee of such Guarantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Guarantor ceases to be a Domestic Subsidiary of the Borrower. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 7 shall be without recourse to or warranty by the Administrative Agent.

8. Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrowers or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrowers or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

11. Authority of Agent. Each Guarantor acknowledges that the rights and responsibilities of the Administrative Agent under this Guarantee with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Guarantee shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and such Guarantor, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

12. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 14.2 of the Credit Agreement.

The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

15. Integration. This Guarantee represents the agreement of each Guarantor and the Administrative Agent with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any other Secured Party relative to the subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents.

No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

17. Section Headings. The Section headings used in this Guarantee are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

(i) demolish or remove all or any material portion of the Improvements, except as may be required by law, if such demolition or removal could reasonably be expected to have a Material Adverse Effect;

(ii) erect any additions to the Improvements or any other structures on the Premises, if such erection could reasonably be expected to have a Material Adverse Effect;

20.6. Insurance. Mortgagor will keep or cause to be kept the Improvements and Personal Property insured against such risks and shall purchase such additional insurance to the extent that is required from time to time pursuant to Section 9.3 of the Credit Agreement. Mortgagor shall pay promptly when due any premiums on such insurance policies and on any renewals thereof. In the event of the foreclosure of this Mortgage or any other transfer of the Premises or Improvements in extinguishment of the indebtedness and other sums secured hereby, all right, title and interest of Mortgagor in and to all casualty insurance policies, and renewals thereof then in force, to the extent assignable shall pass to the purchaser or grantee in connection therewith; provided that Mortgagor’s obligations shall be reduced accordingly.

Mortgagor shall give Mortgagee prompt written notice of any casualty or other damage to the Mortgaged Property or any proceeding for the taking of the Mortgaged Property or any portion thereof or interest therein under power of eminent domain or by condemnation or any similar proceeding, in each case that could reasonably be expected to have a Material Adverse Effect.

20.8. Assignment of Leases and Rents(a) . (a) Mortgagor hereby irrevocably and absolutely grants, transfers and assigns all of its right title and interest in all Leases, together with any and all extensions and renewals thereof for purposes of securing and discharging the performance by Mortgagor of the Obligations. Mortgagor has not assigned or executed any assignment of, and will not assign or execute any assignment of, any other Lease or their respective Rents to anyone other than Mortgagee.

(b) If an Event of Default shall occur and be continuing, Mortgagee shall have the right, power and authority to notify any person that the Leases have been assigned to Mortgagee and that all rents and other obligations are to be paid directly to Mortgagee, whether or not Mortgagee has commenced or completed foreclosure or taken possession of the Premises or the Improvements.

(c) Without Mortgagee’s prior written consent, which consent shall not be unreasonably withheld or delayed, Mortgagor will not enter into, modify, amend, terminate or consent to the cancellation or surrender of any Lease if (i) such Lease, as entered into, modified or amended will not be subordinate to the lien of this Mortgage or (ii) such Lease and all other Leases affecting the Land or the Improvements demise in the aggregate more than 10% of the gross building area of the Improvements or 10% of the total area of the Land.

(d) Subject to Section 1.08(e), Mortgagor has assigned and transferred to Mortgagee all of Mortgagor’s right, title and interest in and to the Rents now or hereafter arising from each Lease heretofore or hereafter made or agreed to by Mortgagor, it being intended that this assignment establish, subject to Section 1.08(e), an absolute transfer and assignment of all Rents and all Leases to Mortgagee and not merely to grant a security interest therein.

(e) So long as an Event of Default shall not have occurred and be continuing, Mortgagee will not exercise any of its rights under Section 1.08(c), and Mortgagor shall have a license to receive and collect, and shall receive and collect, the Rents accruing under any Lease, to enforce the obligations of tenants under the Leases and to exercise all rights and remedies of Landlord under the Leases, and to operate and maintain the Mortgaged Property, subject in each case to compliance with the terms of this Mortgage; but after the happening and during the continuance of any Event of Default, Mortgagee may, at its option, receive and collect all Rents and enter upon the Land, the Premises and Improvements through its officers, agents, employees or attorneys for such purpose and for the operation and maintenance thereof. Mortgagor hereby irrevocably authorizes and directs each tenant, if any, and each successor, if any, to the interest of any tenant under any Lease, respectively, to rely upon any notice of a claimed Event of Default sent by Mortgagee to any such tenant or any of such tenant’s successors in interest, and thereafter to pay Rents to Mortgagee without any obligation or right to inquire as to whether an Event of Default actually exists and even if some notice to the contrary is received from the Mortgagor, who shall have no right or claim against any such tenant or successor in interest for any such Rents so paid to Mortgagee. Each tenant or any of such tenant’s successors in interest from whom Mortgagee or any officer, agent, attorney or employee of Mortgagee shall have collected any Rents, shall be authorized to pay Rents to Mortgagor only after such tenant or any of their successors in interest shall have received written notice from Mortgagee that the Event of Default is no longer continuing (such notice to be given by the Mortgagee promptly after the Event of Default is no longer continuing), unless and until a further notice of an Event of Default is given by Mortgagee to such tenant or any of its successors in interest.

(f) Mortgagee will not become a mortgagee in possession so long as it does not enter or take actual possession of the Mortgaged Property. In addition, Mortgagee, except where Mortgagee or Mortgagee’s agents have acted in bad faith, have been grossly negligent or have committed wilful misconduct in relation to any of the following, shall not be responsible or liable for performing any of the obligations of the landlord under any Lease, for any waste by any

tenant, or others, for any dangerous or defective conditions of any of the Mortgaged Property, for negligence in the management, upkeep, repair or control of any of the Mortgaged Property or any other act or omission by any other person.

(g) Mortgagor shall furnish to Mortgagee, within 30 days after a request by Mortgagee to do so, a written statement containing the names of all tenants, subtenants and concessionaires of the Land, the Premises or Improvements, the terms of any Lease, the space occupied and the rentals or license fees payable thereunder.

20.9. Restrictions on Transfers and Encumbrances. Except as permitted by the Credit Agreement (including, without limitation, pursuant to Sections 10.2, 10.3 and 10.4 thereof), Mortgagor shall not directly or indirectly sell, convey, alienate, assign, lease, sublease, license, mortgage, pledge, encumber or otherwise transfer, create, consent to or suffer the creation of any lien, charges or any form of encumbrance upon any interest in or any part of the Mortgaged Property, or be divested of its title to the Mortgaged Property or any interest therein in any manner or way, whether voluntarily or involuntarily (other than resulting from a condemnation), or engage in any common, cooperative, joint, time-sharing or other congregate ownership of all or part thereof, provided, that Mortgagor may in the ordinary course of business within reasonable commercial standards, enter into easement or covenant agreements that relate to and/or benefit the operation of the Mortgaged Property and that do not materially or adversely affect the use and operation of the same.

20.10. Security Agreement. This Mortgage is both a mortgage of real property and a grant of a security interest in personal property, and shall constitute and serve as a “Security Agreement” within the meaning of the uniform commercial code as adopted in the state wherein the Premises are located (“UCC”). Mortgagor has hereby granted unto Mortgagee a security interest in and to all the Mortgaged Property described in this Mortgage that is not real property. Mortgagor hereby appoints Mortgagee as its true and lawful attorney-in-fact and agent, for Mortgagor and in its name, place and stead, in any and all capacities, to execute any document and to file the same in the appropriate offices (to the extent it may lawfully do so), and to perform each and every act and thing reasonably requisite and necessary to be done to perfect the security interest contemplated by the preceding sentence. Mortgagee shall have all rights with respect to the part of the Mortgaged Property that is the subject of a security interest afforded by the UCC in addition to, but not in limitation of, the other rights afforded Mortgagee hereunder and under the Security Agreement.

20.11. Filing and Recording. Mortgagor will cause this Mortgage, any other security instrument creating a mortgage or security interest in or evidencing the lien hereof upon the Mortgaged Property and each instrument of further assurance to be filed, registered or recorded in such manner and in such places as may be required by any present or future law in order to publish notice of and fully to protect the lien hereof upon, and the mortgage and security interest of Mortgagee in, the Mortgaged Property. Mortgagor will pay all filing, registration and recording fees, all Federal, state, county and municipal recording, documentary or intangible taxes and other taxes, duties, imposts, assessments and charges, and all reasonable expenses incidental to or arising out of or in connection with the execution, delivery and recording of this Mortgage, any mortgage supplemental hereto, any security instrument with respect to the Personal Property or any instrument of further assurance.

20.12. Further Assurances. Upon demand by Mortgagee, Mortgagor will, at the cost of Mortgagor and without expense to Mortgagee, do, execute, acknowledge and deliver all such further acts, deeds, conveyances, mortgages, assignments, notices of assignment, transfers and assurances as Mortgagee shall from time to time reasonably require for the better assuring, conveying, assigning, transferring and confirming unto Mortgagee the property and rights hereby conveyed or assigned or intended now or hereafter so to be, or which Mortgagor may be or may hereafter become bound to convey or assign to Mortgagee, or for carrying out the intention or facilitating the performance of the terms of this Mortgage, or for filing, registering or recording this Mortgage, and on demand, Mortgagor will also execute and deliver and hereby appoints Mortgagee as its true and lawful attorney-in-fact and agent, for Mortgagor and in its name, place and stead, in any and all capacities, to execute and file to the extent it may lawfully do so, one or more financing statements, chattel mortgages or comparable security instruments reasonably requested by Mortgagee to evidence more effectively the lien hereof upon the Personal Property and to perform each and every act and thing requisite and necessary to be done to accomplish the same.

20.13. Additions to Mortgaged Property. All right, title and interest of Mortgagor in and to all extensions, improvements, betterments, renewals, substitutes and replacements of, and all additions and appurtenances to, the Mortgaged Property hereafter acquired by or released to Mortgagor or constructed, assembled or placed by Mortgagor upon the Premises or the Improvements, and all conversions of the security constituted thereby, immediately upon such acquisition, release, construction, assembling, placement or conversion, as the case may be, and in each such case without any further mortgage, conveyance, assignment or other act by Mortgagor, shall become subject to the lien and mortgage and security interest of this Mortgage as fully and completely and with the same effect as though now owned by Mortgagor and specifically described in the grant of the Mortgaged Property above, but at any and all times Mortgagor will execute and deliver to Mortgagee any and all such further assurances, mortgages, conveyances or assignments thereof as Mortgagee may reasonably require for the purpose of expressly and specifically subjecting the same to the lien and mortgage and security interest of this Mortgage.

20.14. No Claims Against Mortgagee. Nothing contained in this Mortgage shall constitute any consent or request by Mortgagee, express or implied, for the performance of any labor or services or the furnishing of any materials or other property in respect of the Mortgaged Property or any part thereof, nor as giving Mortgagor any right, power or authority to contract for or permit the performance of any labor or services or the furnishing of any materials or other property in such fashion as would permit the making of any claim against Mortgagee in respect thereof.

20.15. Fixture Filing. Certain portions of the Mortgaged Property are or will become “fixtures” (as that term is defined in the UCC) on the Land, and this Mortgage, upon being filed for record in the real estate records of the city or town wherein such fixtures are situated, shall operate also as a financing statement filed as a fixture filing in accordance with the applicable provisions of said UCC upon such portions of the Mortgaged Property that are or become fixtures.

SECTION 21.

Defaults and Remedies

21.1. Events of Default. Any Event of Default under the Credit Agreement (as such term is defined therein) shall constitute an Event of Default under this Mortgage.

21.2. Demand for Payment. If an Event of Default shall occur and be continuing, then, upon written demand of Mortgagee, Mortgagor will pay to Mortgagee all amounts due hereunder and under the Guarantee or, if the Mortgagor is the US Borrower, under the Credit Agreement, as applicable, and such further amount as shall be sufficient to cover the costs and expenses of collection, including attorneys’ fees, disbursements and expenses incurred by Mortgagee, and Mortgagee shall be entitled and empowered to institute an action or proceedings at law or in equity for the collection of the sums so due and unpaid, to prosecute any such action or proceedings to judgment or final decree, to enforce any such judgment or final decree against Mortgagor and to collect, in any manner provided by law, all moneys adjudged or decreed to be payable.

21.3. Rights To Take Possession, Operate and Apply Revenues(a) . (a) If an Event of Default shall occur and be continuing, Mortgagor shall, upon demand of Mortgagee, forthwith surrender to Mortgagee actual possession of the Mortgaged Property and, if and to the extent not prohibited by applicable law, Mortgagee itself, or by such officers or agents as it may appoint, may then enter and take possession of all the Mortgaged Property without the appointment of a receiver or an application therefor, exclude Mortgagor and its agents and employees wholly therefrom, and have access to the books, papers and accounts of Mortgagor.

(b) If Mortgagor shall for any reason fail to surrender or deliver the Mortgaged Property or any part thereof after such demand by Mortgagee, Mortgagee may, to the extent not prohibited by applicable law, obtain a judgment or decree conferring upon Mortgagee the right to immediate possession or requiring Mortgagor to deliver immediate possession of the Mortgaged Property to Mortgagee, to the entry of which judgment or decree Mortgagor hereby specifically consents. Mortgagor will pay to Mortgagee, upon demand, all reasonable expenses of obtaining such judgment or decree, including reasonable compensation to Mortgagee’s attorneys and agents with interest thereon at the Default Interest Rate; and all such expenses and compensation shall, until paid, be secured by this Mortgage.

(c) Upon every such entry or taking of possession, Mortgagee may, to the extent not prohibited by applicable law, hold, store, use, operate, manage and control the Mortgaged Property, conduct the business thereof and, from time to time, (i) make all necessary and proper maintenance, repairs, renewals, replacements, additions, betterments and improvements thereto and thereon, (ii) purchase or otherwise acquire additional fixtures, personalty and other property, (iii) insure or keep the Mortgaged Property insured, (iv) manage and operate the Mortgaged Property and exercise all the rights and powers of Mortgagor to the same extent as Mortgagor could in its own name or otherwise with respect to the same, or (v) enter into any and all agreements with respect to the exercise by others of any of the powers herein granted Mortgagee, all as may from time to time be directed or determined by Mortgagee to be in its best interest and Mortgagor hereby appoints Mortgagee as its true and lawful attorney-in-fact and agent, for

Mortgagor and in its name, place and stead, in any and all capacities, to perform any of the foregoing acts. Mortgagee may collect and receive all the Rents, issues, profits and revenues from the Mortgaged Property, including those past due as well as those accruing thereafter, and, after deducting (i) all expenses of taking, holding, managing and operating the Mortgaged Property (including compensation for the services of all persons employed for such purposes), (ii) the costs of all such maintenance, repairs, renewals, replacements, additions, betterments, improvements, purchases and acquisitions, (iii) the costs of insurance, (iv) such taxes, assessments and other similar charges as Mortgagee may at its option pay, (v) other proper charges upon the Mortgaged Property or any part thereof and (vi) the compensation, expenses and disbursements of the attorneys and agents of Mortgagee, Mortgagee shall apply the remainder of the moneys and proceeds so received first to the payment of the Mortgagee for the satisfaction of the Obligations in accordance with Section 2.08, and second, if there is any surplus, to Mortgagor, subject to the entitlement of others thereto under applicable law.

(d) Whenever, before any sale of the Mortgaged Property under Section 2.06, all Obligations that are then due shall have been paid and all Events of Default fully cured, Mortgagee will surrender possession of the Mortgaged Property back to Mortgagor, its successors or assigns. The same right of taking possession shall, however, arise again if any subsequent Event of Default shall occur and be continuing.

21.4. Right To Cure Mortgagor’s Failure to Perform. Should Mortgagor fail in the payment, performance or observance of any term, covenant or condition required by this Mortgage or the Security Agreement (with respect to the Mortgaged Property), Mortgagee may pay, perform or observe the same. Pursuant to the exercise of its rights under this Section 2.04, Mortgagee is hereby empowered to enter and to authorize others to enter upon the Premises or the Improvements or any part thereof for the purpose of performing or observing any such defaulted term, covenant or condition without having any obligation to so perform or observe and without thereby becoming liable to Mortgagor, to any person in possession holding under Mortgagor or to any other person. The expenses of the Administrative Agent incurred in connection with actions undertaken as provided in this Section, together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under the Credit Agreement, from the date of payment by the Administrative Agent to the date reimbursed by the Mortgagor, shall be payable by such Mortgagor to the Administrative Agent on demand.

21.5. Right to a Receiver. If an Event of Default shall occur and be continuing, Mortgagee, upon application to a court of competent jurisdiction, shall be entitled as a matter of right to the appointment of a receiver to take possession of and to operate the Mortgaged Property and to collect and apply the Rents. The receiver shall have all of the rights and powers permitted under the laws of the state wherein the Mortgaged Property is located. Mortgagor shall pay to Mortgagee upon demand all reasonable expenses, including receiver’s fees, reasonable attorney’s fees and disbursements, costs and agent’s compensation incurred pursuant to the provisions of this Section 2.05; and all such expenses shall be secured by this Mortgage and shall be, without demand, immediately repaid by Mortgagor to Mortgagee with interest thereon at the Default Interest Rate.

21.6. Foreclosure and Sale(a) . (a) If an Event of Default shall occur and be

continuing, Mortgagee shall have the STATUTORY POWER OF SALE.

(b) The Mortgaged Property may be sold subject to unpaid taxes, leases and Permitted Encumbrances, and, after deducting all costs, fees and expenses of Mortgagee (including costs of evidence of title in connection with the sale), Mortgagee or an officer that makes any sale shall apply the proceeds of sale in the manner set forth in Section 2.08.

(c) Any foreclosure or other sale of less than the whole of the Mortgaged Property or any defective or irregular sale made hereunder shall not exhaust the power of foreclosure or of sale provided for herein; and subsequent sales may be made hereunder until the Obligations have been satisfied, or the entirety of the Mortgaged Property has been sold.

(d) If an Event of Default shall occur and be continuing, Mortgagee may instead of, or in addition to, exercising the rights described in Section 2.06(a) above and either with or without entry or taking possession as herein permitted, proceed by a suit or suits in law or in equity or by any other appropriate proceeding or remedy (i) to specifically enforce payment of some or all of the Obligations, or the performance of any term, covenant, condition or agreement of this Mortgage or any other Credit Document or any other right, or (ii) to pursue any other remedy available to Mortgagee, all as Mortgagee shall determine most effectual for such purposes, subject to any applicable terms of the Guarantee, the Credit Agreement and the other Credit Documents.

21.7. Other Remedies(a) . (a) In case an Event of Default shall occur and be continuing, Mortgagee may also exercise, to the extent not prohibited by law, any or all of the remedies available to a secured party under the UCC.

(b) In connection with a sale of the Mortgaged Property or any Personal Property and the application of the proceeds of sale as provided in Section 2.08, Mortgagee shall be entitled to enforce payment of and to receive up to the principal amount of the Obligations, plus all other charges, payments and costs due under this Mortgage.

(c) Subject to the provisions of the Credit Agreement, to the extent permitted by law, if after foreclosure of this Mortgage or Mortgagee’s sale hereunder, there shall remain any deficiency with respect to any amounts payable under the Credit Documents, including hereunder, or any amounts secured hereby, Mortgagee shall be entitled to recover a deficiency judgment for any portion of the aggregate principal amount of the Obligations remaining unpaid, with interest. If Mortgagee shall institute any proceedings to recover such deficiency or deficiencies, all such amounts shall continue to bear interest at the Default Rate. Subject to the provisions of the Credit Agreement, to the extent permitted by law, Mortgagor waives any defense to Mortgagee’s recovery against Mortgagor of any deficiency after any foreclosure sale of the Mortgaged Property. Subject to the provisions of the Credit Agreement, to the extent permitted by law, Mortgagor expressly waives any defense or benefits that may be derived from any statute granting Mortgagor any defense to any such recovery by Mortgagee. Subject to the provisions of the Credit Agreement, in addition, Mortgagee shall be entitled to recovery of all of their reasonable costs and expenditures (including any court imposed costs) in connection with such proceedings, including their reasonable attorneys’ fees, appraisal fees and any other costs,

fees and expenditures. This provision shall survive any foreclosure or sale of the Mortgaged Property, any portion thereof and/or the extinguishment of the lien hereof.

21.8. Application of Sale Proceeds and Rents. After any foreclosure sale of all or any of the Mortgaged Property, Mortgagee shall receive and at any time thereafter apply the proceeds of the sale together with any Rents that may have been collected and any other sums that then may be held by Mortgagee under this Mortgage as follows:

FIRST, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Mortgage, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of any Mortgagor and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

SECOND, to the Secured Parties, an amount equal to all Obligations owing to them on the date of any distribution, and, if such moneys shall be insufficient to pay such amounts in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the unpaid amounts thereof; and

THIRD, any surplus then remaining shall be paid to Mortgagor or its successor or assign or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

Borrower shall remain liable for any deficiency in the proceeds. Upon any sale of the Mortgaged Property by the Mortgagee (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Mortgagee or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Mortgaged Property so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Mortgagee or such officer or be answerable in any way for the misapplication thereof.

21.9. Mortgagor as Tenant Holding Over. Mortgagor agrees for itself and all Persons claiming by, through or under it, that, to the extent allowed by applicable law, subsequent to foreclosure hereunder in accordance with this Mortgage and applicable law, if Mortgagor shall hold possession of the Mortgaged Property or any part thereof, Mortgagor or the Persons so holding possession shall be guilty of trespass and shall be deemed a tenant holding over and any such tenant failing or refusing to surrender possession upon demand shall be guilty of forcible detainer and shall be liable to such purchasers for reasonable rental on said premises, and shall be summarily dispossessed or evicted according to provisions of law applicable to tenants holding over.

21.10. Waiver of Appraisement, Valuation, Stay, Extension and Redemption Laws. Mortgagor waives, to the extent not prohibited by law, (i) the benefit of all laws now existing or that hereafter may be enacted (x) providing for any appraisement or valuation of any

portion of the Mortgaged Property and/or (y) in any way extending the time for the enforcement or the collection of amounts due under any of the Obligations or creating or extending a period of redemption from any sale made in collecting said debt or any other amounts due Mortgagee, (ii) any right to at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any homestead exemption, stay, statute of limitations, extension or redemption, or sale of the Mortgaged Property as separate tracts, units or estates or as a single parcel in the event of foreclosure or notice of deficiency, and (iii) all rights of redemption, valuation, appraisement, stay of execution, notice of election to mature or declare due the whole of or each of the Obligations and marshaling in the event of foreclosure of this Mortgage.

21.11. Discontinuance of Proceedings. In case Mortgagee shall proceed to enforce any right, power or remedy under this Mortgage by foreclosure, entry or otherwise, and such proceedings shall be discontinued or abandoned for any reason, or shall be determined adversely to Mortgagee, then and in every such case Mortgagor and Mortgagee shall be restored to their former positions and rights hereunder, and all rights, powers and remedies of Mortgagee shall continue as if no such proceeding had been taken.

21.12. Suits To Protect the Mortgaged Property. Mortgagee shall have power (a) upon the occurrence and during the continuance of an Event of Default, to institute and maintain suits and proceedings to prevent any impairment of the Mortgaged Property by any acts that may be unlawful or in violation of this Mortgage, (b) to preserve or protect its interest in the Mortgaged Property and in the Rents arising therefrom and (c) to restrain the enforcement of or compliance with any legislation or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of or compliance with such enactment, rule or order would impair the security or be prejudicial to the interest of Mortgagee hereunder.

21.13. Filing Proofs of Claim. In case of any receivership, insolvency, bankruptcy, reorganization, arrangement, adjustment, composition or other proceedings affecting Mortgagor, Mortgagee shall, to the extent permitted by law, be entitled to file such proofs of claim and other documents as may be necessary or advisable in order to have the claims of Mortgagee allowed in such proceedings for the Obligations secured by this Mortgage at the date of the institution of such proceedings and for any interest accrued, late charges and additional interest or other amounts due or that may become due and payable hereunder after such date.

21.14. Possession by Mortgagee. After the occurrence and during the continuance of an Event of Default, notwithstanding the appointment of any receiver, liquidator or trustee of Mortgagor, any of its property or the Mortgaged Property, Mortgagee shall be entitled, to the extent not prohibited by law, to remain in possession and control of all parts of the Mortgaged Property now or hereafter granted under this Mortgage to Mortgagee in accordance with the terms hereof and applicable law.

21.15. Waiver. (a) No delay or failure by Mortgagee to exercise any right, power or remedy accruing upon any breach or Event of Default shall exhaust or impair any such right, power or remedy or be construed to be a waiver of any such breach or Event of Default or acquiescence therein; and every right, power and remedy given by this Mortgage to Mortgagee may be exercised from time to time and as often as may be deemed expedient by Mortgagee. No

consent or waiver by Mortgagee to or of any breach or Event of Default by Mortgagor in the performance of the Obligations shall be deemed or construed to be a consent or waiver to or of any other breach or Event of Default in the performance of the same or of any other Obligations by Mortgagor hereunder. No failure on the part of Mortgagee to complain of any act or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall constitute a waiver by Mortgagee of its rights hereunder or impair any rights, powers or remedies consequent on any future Event of Default by Mortgagor.

(b) Even if Mortgagee (i) grants some forbearance or an extension of time for the payment of any sums secured hereby, (ii) takes other or additional security for the payment of any sums secured hereby, (iii) waives or does not exercise some right granted herein or under the Credit Documents, (iv) releases a part of the Mortgaged Property from this Mortgage, (v) agrees to change some of the terms, covenants, conditions or agreements of any of the Credit Documents, (vi) consents to the filing of a map, plat or replat affecting the Premises, (vii) consents to the granting of an easement or other right affecting the Premises or (viii) makes or consents to an agreement subordinating Mortgagee’s lien on the Mortgaged Property hereunder; no such act or omission shall preclude Mortgagee from exercising any other right, power or privilege herein granted or intended to be granted in the event of any breach or Event of Default then made or of any subsequent default; nor, except as otherwise expressly provided in an instrument executed by Mortgagee, shall this Mortgage be altered thereby. In the event of the sale or transfer by operation of law or otherwise of all or part of the Mortgaged Property, Mortgagee is hereby authorized and empowered to deal with any vendee or transferee with reference to the Mortgaged Property secured hereby, or with reference to any of the terms, covenants, conditions or agreements hereof, as fully and to the same extent as it might deal with the original parties hereto and without in any way releasing or discharging any liabilities, obligations or undertakings.

21.16. Remedies Cumulative. No right, power or remedy conferred upon or reserved to Mortgagee by this Mortgage is intended to be exclusive of any other right, power or remedy, and each and every such right, power and remedy shall be cumulative and concurrent and in addition to any other right, power and remedy given hereunder or now or hereafter existing at law or in equity or by statute.

SECTION 22.

Miscellaneous

22.1. Partial Invalidity. In the event any one or more of the provisions contained in this Mortgage shall for any reason be held to be invalid, illegal or unenforceable in any respect, such validity, illegality or unenforceability shall, at the option of Mortgagee, not affect any other provision of this Mortgage, and this Mortgage shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein or therein.

22.2. Application of Payments. In the event that any part of the Obligations cannot lawfully be secured hereby, or in the event that the mortgage and security interest hereof cannot be lawfully enforced to pay any part of the Obligations, or in the event that the mortgage or security interest created by this Mortgage shall be invalid or unenforceable as to any part of

the Obligations, then all payments on the Obligations shall be deemed to have been first applied to the complete payment and liquidation of that part of the Obligations which is not secured by this Mortgage and the unsecured portion of the Obligations shall be completely paid and liquidated prior to the payment and liquidation of the remaining secured portion of the Obligations.

22.3. Amendments; Etc. This Mortgage may not be amended, modified or supplemented, except in a writing signed by each of the parties hereto and otherwise in accordance with the provisions of the Credit Agreement.

22.4. Renewal; Etc. Mortgagee may at any time and from time to time renew or extend this Mortgage, or alter or modify the same in any way, or waive any of the terms, covenants or conditions hereof in whole or in part and may release any portion of the Mortgaged Property or any other security, and grant such extensions and indulgences in relation to the Obligations as Mortgagee may determine, without the consent of any junior lienor or encumbrancer and without any obligation to give notice of any kind thereto and without in any manner affecting the priority of the mortgage and security interest hereof on any part of the Mortgaged Property; provided that nothing in this Section 3.04 shall grant Mortgagee the right to alter or modify the Mortgage without the written consent of the Mortgagor.

22.5. Future Advances. This Mortgage is executed and delivered to secure, among other things, Mortgagor’s guaranty of future advances under the Credit Agreement. It is understood and agreed that this Mortgage secures Mortgagor’s guaranty of present and future advances made pursuant to the Credit Agreement and that the lien of such future advances shall relate to the date of this Mortgage.

22.6. Compliance With Usury Law. The Credit Documents are intended to be performed in accordance with, and only to the extent permitted by, all applicable governmental rules and legal requirements. It is expressly stipulated and agreed to be the intent of Mortgagor and Mortgagee at all times to comply with the applicable [STATE] law governing the maximum rate or amount of interest payable on or in connection with the Obligations (or applicable United States federal law to the extent that it permits Mortgagee to contract for, charge, take, reserve or receive a greater amount of interest than under [STATE] law). If the applicable law is ever judicially interpreted so as to render usurious any amount called for under the Credit Documents, or contracted for, charged, taken, reserved or received with respect to the extension of credit evidenced by the Credit Documents or if acceleration of the maturity of the Obligations or if any prepayment by Mortgagor results in Mortgagor having paid any interest in excess of that permitted by law, then it is Mortgagor’s and Mortgagee’s express intent that all excess amounts theretofore collected by Mortgagee be credited on the principal balance due under the Credit Documents (or, if the Credit Documents have been or would thereby be paid in full, refunded to Mortgagor), and the provisions of the Credit Documents immediately be deemed reformed and the amounts thereafter collectible thereunder reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder. The right to accelerate maturity of Obligations does not include the right to accelerate any interest that has not otherwise accrued on the date of such acceleration, and Mortgagee does not intend to collect any unearned interest in the event of acceleration. All sums paid or agreed to be paid to Mortgagee for the use,

forbearance or detention of the Obligations shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of the Obligations until payment in full so that the rate or amount of interest on account of the Obligations does not exceed the applicable usury ceiling.

22.7. Notices. All notices (including any notice to the Mortgagee pursuant to Sections 34-25-10(b) and 34-25-11 of the [STATE] General Laws, as amended), requests and demands to or upon the respective parties hereto to be effective shall be in writing (including by facsimile transmission), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered, or three days after being deposited in the mail, postage prepaid, or, in the case of telecopy notice, when received, addressed to the Mortgagor and/or the Mortgagee at the addresses set forth on the first page of this Mortgage.

22.8. Successors and Assigns. All of the grants, covenants, terms, provisions and conditions herein shall run with the Premises and the Improvements and shall apply to, bind and inure to, the benefit of the permitted successors and assigns of Mortgagor and the successors and assigns of Mortgagee.

22.9. Satisfaction and Cancellation(a) . (a) The conveyance to Mortgagee of the Mortgaged Property as security created and consummated by this Mortgage shall be null and void when all the Obligations under the Credit Documents have been indefeasibly paid in full in accordance with the terms of the Credit Documents and the Lenders have no further commitment to make Loans under the Credit Agreement, no Letters of Credit are outstanding and the Letter of Credit Issuer has no further obligation to issue Letters of Credit under the Credit Agreement.

(b) Upon a sale, conveyance, lease, assignment, transfer, pledge or financing permitted pursuant to the provisions of Sections 10.3 or 10.4 of the Credit Agreement, including, without limitation, a sale by Mortgagor of all or any portion of the Mortgaged Property that is permitted by the Credit Agreement and the application of the net proceeds of such sale or financing in accordance with the Credit Agreement, the lien of this Mortgage shall be released from the applicable portion of the Mortgaged Property.

(c) Mortgagor shall automatically be released from its obligations hereunder and the Lien on the Mortgaged Property shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Mortgagor ceases to be a Domestic Subsidiary of the US Borrower.

(d) In connection with any termination or release pursuant to paragraph (a) or (b) or (c), the Mortgage shall be marked “SATISFIED” by the Mortgagee, this Mortgage shall be canceled of record at the request and at the expense of the Mortgagor, and the lien of this Mortgage shall be released from the applicable portion of the Mortgaged Property. Mortgagee shall execute any documents reasonably requested by Mortgagor to accomplish the foregoing or to accomplish any release contemplated by this Section 3.09 and Mortgagor will pay all costs and expenses, including reasonable attorneys’ fees, disbursements and other charges, incurred by Mortgagee in connection with the preparation and execution of such documents.

(e) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Administrative Agent shall execute and deliver to Mortgagor, at Mortgagor’s expense, all documents that Mortgagor shall reasonably request to evidence such termination or release.

(g) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Pledge Agreement shall refer to this Pledge Agreement as a whole and not to any particular provision of this Pledge Agreement, and Section references are to Sections of this Pledge Agreement unless otherwise specified. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation”.

(h) The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms.

2. Grant of Security. Each Pledgor hereby transfers, assigns and pledges to the Administrative Agent for the ratable benefit of the Secured Parties, and hereby grants to the Administrative Agent for the ratable benefit of the Secured Parties, a security interest, which security interest shall attach immediately upon the Closing Time (“Security Interest”), in all of such Pledgor’s right, title and interest in the following, whether now owned or existing or hereafter acquired or existing (collectively, the “Collateral”):

4. Delivery of the Collateral. All certificates or instruments, if any, representing or evidencing the Collateral shall be promptly delivered to and held by or on behalf of the Administrative Agent pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments or documents of transfer or assignment in blank, all in form and substance reasonably satisfactory to the Administrative Agent.

Each schedule so delivered shall supersede any prior schedules so delivered.

5. Representations and Warranties. Each Pledgor represents and warrants as follows:

(a) Schedule 2 hereto (i) correctly represents as of the date hereof (A) the issuer, the certificate number, the Pledgor and the record and beneficial owner, the number and class and the percentage of the issued and outstanding Equity Interests of such class of all Pledged Shares and (B) the issuer, the initial principal amount, the Pledgor and holder, date of and maturity date of all Pledged Debt and (ii) together with the comparable schedule to each supplement hereto, includes all Equity Interests, debt securities and promissory notes required to be pledged hereunder.

(b) Such Pledgor is the legal and beneficial owner of the Collateral pledged or assigned by such Pledgor hereunder free and clear of any Lien, except for the Lien created by this Pledge Agreement.

(c) As of the date of this Pledge Agreement, the Pledged Shares pledged by such Pledgor hereunder have been duly authorized and validly issued and, in the case of Pledged Shares issued by a corporation, are fully paid and non-assessable.

(d) The execution and delivery by such Pledgor of this Pledge Agreement and the pledge of the Collateral pledged by such Pledgor hereunder pursuant hereto create a valid and perfected first-priority security interest in the Collateral, securing the payment of the Obligations, in favor of the Administrative Agent for the ratable benefit of the Secured Parties.

(e) Such Pledgor has full power, authority and legal right to pledge all the Collateral pledged by such Pledgor pursuant to this Pledge Agreement and this Pledge Agreement constitutes a legal, valid and binding obligation of each Pledgor, enforceable in accordance with its terms, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

6. Certification of Limited Liability Company, Limited Partnership Interests and Pledged Debt. (a) The Equity Interests in any Domestic Subsidiary that is organized as a limited liability company or limited partnership and pledged hereunder shall be represented by a certificate and in the organizational documents of such Domestic Subsidiary, the applicable Pledgor shall cause the issuer of such interests to elect to treat such interests as a “security” within the meaning of Article 8 of the Uniform Commercial Code of its jurisdiction of organization or formation, as applicable, by including in its organizational documents language substantially similar to the following and, accordingly, such interests shall be governed by Article 8 of the Uniform Commercial Code:

“The Partnership/Company hereby irrevocably elects that all partnership/membership interests in the Partnership/Company shall be securities governed by Article 8 of the Uniform Commercial Code of [jurisdiction of organization or formation, as applicable]. Each certificate evidencing partnership/membership interests in the Partnership/Company shall bear the following legend: “This certificate evidences an interest in [name of Partnership/LLC] and shall be a security for purposes of Article 8 of the Uniform Commercial Code.” No change to this provision shall be effective until all outstanding certificates have been surrendered for cancelation and any new certificates thereafter issued shall not bear the foregoing legend.”

(b) Each Pledgor will cause any Indebtedness for borrowed money owed to such Pledgor and required to be pledged hereunder to be evidenced by a duly executed promissory note that is pledged and delivered to the Administrative Agent pursuant to the terms hereof.

7. Further Assurances. Each Pledgor agrees that at any time and from time to time, at the expense of such Pledgor, it will execute any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, fixture filings, mortgages, deeds of trust and other

documents), which may be required under any applicable law, or which the Administrative Agent or the Required Lenders may reasonably request, in order (x) to perfect and protect any pledge, assignment or security interest granted or purported to be granted hereby (including the priority thereof) or (y) to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral.

8. Voting Rights; Dividends and Distributions; Etc. (a) So long as no Event of Default shall have occurred and be continuing:

(i) Each Pledgor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Collateral or any part thereof for any purpose not prohibited by the terms of this Pledge Agreement or the other Credit Documents; and

(ii) The Administrative Agent shall execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments or documents as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above.

(b) Subject to paragraph (c) below, each Pledgor shall be entitled to receive and retain and use, free and clear of the Lien of this Pledge Agreement, any and all dividends, distributions, principal and interest made or paid in respect of the Collateral to the extent permitted by the Credit Agreement; provided, however, that any and all noncash dividends, interest, principal or other distributions that would constitute Pledged Shares or Pledged Debt, whether resulting from a subdivision, combination or reclassification of the outstanding Equity Interests of the issuer of any Pledged Shares or received in exchange for Pledged Shares or Pledged Debt or any part thereof, or in redemption thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which such issuer may be a party or otherwise, shall be, and shall be forthwith delivered to the Administrative Agent to hold as, Collateral and shall, if received by such Pledgor, be received in trust for the benefit of the Administrative Agent, be segregated from the other property or funds of such Pledgor and be forthwith delivered to the Administrative Agent as Collateral in the same form as so received (with any necessary indorsement).

(c) Upon written notice to a Pledgor by the Administrative Agent following the occurrence and during the continuance of an Event of Default,

(i) all rights of such Pledgor to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 8(a)(i) shall cease, and all such rights shall thereupon become vested in the Administrative Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights during the continuance of such Event of Default, provided that, unless otherwise directed by the Required Lenders, the Administrative Agent shall have the right from time to time following the occurrence and during the continuance of an Event of Default to permit the Pledgors to exercise such rights. After all Events of Default have been cured or waived and the US Borrower has delivered to the Administrative Agent a certificate to that effect, each Pledgor will have the right to exercise the voting and consensual rights that such Pledgor would otherwise

be entitled to exercise pursuant to the terms of Section 8(a)(i) (and the obligations of the Administrative Agent under Section 8(a)(ii) shall be reinstated);

(ii) all rights of such Pledgor to receive the dividends, distributions and principal and interest payments that such Pledgor would otherwise be authorized to receive and retain pursuant to Section 8(b) shall cease, and all such rights shall thereupon become vested in the Administrative Agent, which shall thereupon have the sole right to receive and hold as Collateral (subject to Section 12) such dividends, distributions and principal and interest payments during the continuance of such Event of Default. After all Events of Default have been cured or waived and the US Borrower has delivered to the Administrative Agent a certificate to that effect, the Administrative Agent shall repay to each Pledgor (unless previously applied to the Obligations) (and, in any event, without interest) all dividends, distributions and principal and interest payments that such Pledgor would otherwise be permitted to receive, retain and use pursuant to the terms of Section 8(b);

(iii) all dividends, distributions and principal and interest payments that are received by such Pledgor contrary to the provisions of Section 8(b) shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other property or funds of such Pledgor and shall forthwith be delivered to the Administrative Agent as Collateral in the same form as so received (with any necessary indorsements); and

(iv) in order to permit the Administrative Agent to receive all dividends, distributions and principal and interest payments to which it may be entitled under Section 8(b) above, to exercise the voting and other consensual rights that it may be entitled to exercise pursuant to Section 8(c)(i) above, and to receive all dividends, distributions and principal and interest payments that it may be entitled to under Sections 8(c)(ii) and (c)(iii) above, such Pledgor shall, if necessary, upon written notice from the Administrative Agent, from time to time execute and deliver to the Administrative Agent, appropriate proxies, dividend payment orders and other instruments or documents as the Administrative Agent may reasonably request.

9. Transfers and Other Liens; Additional Collateral; Etc. Each Pledgor shall (a) not (i) except as permitted by the Credit Agreement, sell or otherwise dispose of, or grant any option or warrant with respect to, any of the Collateral or (ii) create or suffer to exist any consensual Lien upon or with respect to any of the Collateral, except for the Lien under this Pledge Agreement, provided that in the event such Pledgor sells or otherwise disposes of assets permitted by the Credit Agreement and such assets are or include any of the Collateral, the Administrative Agent shall release such Collateral to such Pledgor free and clear of the Lien under this Pledge Agreement concurrently with the consummation of such sale;

(b) pledge and, if applicable, cause each Domestic Subsidiary to pledge, to the Administrative Agent for the benefit of the Secured Parties, immediately upon acquisition thereof, all the capital stock and all evidence of Indebtedness held or received by such Pledgor or Domestic Subsidiary required to be pledged hereunder pursuant to Section 9.12 of the Credit Agreement, in each case pursuant to a supplement to this Pledge Agreement substantially in the form of Annex A hereto (it being understood that the execution and delivery of such a supplement shall not require the consent of any Pledgor hereunder and that the rights and

obligations of each Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new Subsidiary Pledgor as a party to this Pledge Agreement); and

(c) defend its and the Administrative Agent’s title or interest in and to all the Collateral (and in the Proceeds thereof) against any and all Liens (other than the Lien of this Pledge Agreement), however arising, and any and all Persons whomsoever.

10. Administrative Agent Appointed Attorney-in-Fact. Each Pledgor hereby appoints, which appointment is irrevocable and coupled with an interest, the Administrative Agent as such Pledgor’s attorney-in-fact, with full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, to take any action and to execute any instrument or document, in each case after the occurrence and during the continuance of an Event of Default, that the Administrative Agent may deem reasonably necessary or advisable to accomplish the purposes of this Pledge Agreement, including to receive, indorse and collect all instruments made payable to such Pledgor representing any dividend, distribution or principal or interest payment in respect of the Collateral or any part thereof and to give full discharge for the same.

11. The Administrative Agent’s Duties. The powers conferred on the Administrative Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Shares, whether or not the Administrative Agent or any other Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property.

12. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Administrative Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the NY UCC (whether or not the NY UCC applies to the affected Collateral) and also may without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange broker’s board or at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral. The Administrative Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Administrative Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or

appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Administrative Agent or any Secured Party shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, and the Administrative Agent or such Secured Party may subject to (x) the satisfaction in full in cash of all payments due pursuant to Section 12(b)(i), and (y) the ratable satisfaction of the Obligations in accordance with Section 12(b)(ii) pay the purchase price by crediting the amount thereof against the Obligations. Each Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, each Pledgor hereby waives any claim against the Administrative Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Administrative Agent accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral at any time after receipt as follows:

(i) first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Pledge Agreement, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of any Pledgor and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

(iii) third, any surplus then remaining shall be paid to the Pledgors or their successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

(d) All payments received by any Pledgor after the occurrence and during the continuance of an Event of Default in respect of the Collateral shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other property or funds of such Pledgor and shall be forthwith delivered to the Administrative Agent as Collateral in the same form as so received (with any necessary indorsement).

(e) Each Pledgor hereby consents to the transfer, at any time after the occurrence and during the continuance of an Event of Default, of any Pledged Shares to the Administrative Agent or its designee and to the substitution, at any time after the occurrence and during the continuance of an Event of Default, of the Administrative Agent or its designee as a partner, member or shareholder of the limited liability company, partnership or other entity that issued the Pledged Shares.

13. Amendments, etc. with Respect to the Obligations; Waiver of Rights. Each Pledgor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Pledgor and without notice to or further assent by any Pledgor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement or documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Pledge Agreement or any property subject thereto. When making any demand hereunder against any Pledgor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the US Borrower or any Pledgor or pledgor, and any failure by the Administrative Agent or any other Secured Party to make any such demand or to collect any payments from the US Borrower or any Pledgor or pledgor or any release of the US Borrower or any Pledgor or pledgor shall not relieve any Pledgor in respect of which a demand or collection is not made or any Pledgor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Pledgor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

14. Continuing Security Interest; Assignments Under the Credit Agreement; Release.

This Pledge Agreement and the security interest granted hereby shall terminate on the first date on which all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding.

(b) A Subsidiary Pledgor shall automatically be released from its obligations hereunder and the Pledge of such Subsidiary Pledgor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Subsidiary Pledgor ceases to be a Domestic Subsidiary of the US Borrower.

(c) Upon any sale or other transfer by any Pledgor of any Collateral that is permitted under the Credit Agreement, or upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 14.1 of the Credit Agreement, the obligations of such Pledgor with respect to such Collateral and the security interest granted hereby in such Collateral shall be automatically released and such Collateral sold free and clear of the Lien and Security Interests created hereby.

(d) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Administrative Agent shall execute and deliver to any Pledgor, at such Pledgor’s expense, all documents that such Pledgor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 14 shall be without recourse to or warranty by the Administrative Agent.

15. Reinstatement. This Pledge Agreement shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Pledgor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the US Borrower or any other Pledgor or any substantial part of its property, or otherwise, all as though such payments had not been made.

16. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 14.2 of the Credit Agreement.

3.1. Title: No Other Liens. Except for the Security Interest granted to the Administrative Agent for the ratable benefit of the Secured Parties pursuant to this Security Agreement, the Liens permitted by the Credit Agreement and any Liens securing Indebtedness which is no longer outstanding or any Liens with respect to commitments to lend which have been terminated, such Grantor owns each item of the Collateral free and clear of any and all Liens or claims of others.

3.2. Perfected First Priority Liens. (a) Subject to the limitations set forth in clause (b) of this Section 3.2, the Security Interests granted pursuant to this Security Agreement (i) will constitute valid perfected Security Interests in the Collateral in favor of the Administrative Agent, for the ratable benefit of the Secured Parties, as collateral security for the Obligations, upon (A) completion of all filings, registrations, recordings and other actions specified in Section 6 of the Perfection Certificate (as such information is updated pursuant to Section 9.1(d) of the Credit Agreement) to the extent that a Security Interest may be perfected by the filing of any UCC financing statement, (B) in the case of Equipment that is covered by a certificate of title, the filing with the registrar of motor vehicles or other appropriate authority in the applicable jurisdiction (as specified in the Perfection Certificate (as such information is updated pursuant to Section 9.1(d) of the Credit Agreement)) of an application requesting the notation of the Security Interest created hereunder on such certificate of title and (C) completion of the filing, registration and recording of a fully executed agreement in the form hereof (or a supplement hereto) and containing a description of all Collateral constituting Intellectual Property in the United Stated Patent and Trademark Office within the three-month period (commencing as of the date hereof) or, in the case of Collateral constituting Intellectual Property acquired after the date hereof, thereafter pursuant to 35 USC §261 and 15 USC § 1060 and the regulations thereunder with respect to United States Patents and United States registered Trademarks and in the United States Copyright Office within the one-month period (commencing as of the date hereof) or, in the case of Collateral constituting Intellectual Property acquired after the date hereof, thereafter with

Each Grantor agrees promptly to provide the Administrative Agent with certified organizational documents reflecting any of the changes described in the first sentence of this paragraph.

Each Grantor also agrees promptly to notify the Administrative Agent if any material portion of the Collateral is damaged or destroyed.

4.3. Notices. Each Grantor will advise the Administrative Agent and the Lenders promptly, in reasonable detail, of any Lien of which it has knowledge (other than the Security Interests created hereby or Liens permitted under the Credit Agreement) on any of the Collateral which would adversely affect, in any material respect, the ability of the Administrative Agent to exercise any of its remedies hereunder.

4.4. Special Covenants with Respect to Equipment. (a) Each Grantor shall, promptly after the acquisition by such Grantor of any item of Equipment that is covered by a certificate of title under a statute of any jurisdiction under the law of which indication of a Security Interest on such certificate is required as a condition of perfection thereof, execute and file with the registrar of motor vehicles or other appropriate authority in such jurisdiction an application or other document requesting the notation or other indication of the Security Interest created hereunder on such certificate of title.

(c) At the Administrative Agent’s request at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Administrative Agent the certificates of title covering each item of Equipment the perfection of which is governed by the notation on the certificate of title of the Administrative Agent’s Security Interest created hereunder.

5. Remedial Provisions.

5.1. Certain Matters Relating to Accounts. (a) At any time after the occurrence and during the continuance of an Event of Default, the Administrative Agent shall have the right to make test verifications of the Accounts in any manner and through any medium that it reasonably considers advisable, and each Grantor shall furnish all such assistance and information as the Administrative Agent may require in connection with such test verifications. The Administrative Agent shall have the absolute right to share any information it gains from such inspection or verification with any Secured Party.

(b) The Administrative Agent hereby authorizes each Grantor to collect such Grantor’s Accounts and the Administrative Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required in writing by the Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Accounts, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly endorsed by such Grantor to the Administrative Agent if required, in a Collateral Account maintained under the sole dominion and control of and on terms and conditions reasonably satisfactory to the Administrative Agent, subject to withdrawal by the Administrative Agent for the account of the Secured Parties only as provided in Section 5.5, and (ii) until so turned over, shall be held by such Grantor in trust for the Administrative Agent and the Secured Parties, segregated from other funds of such Grantor. Each such deposit of Proceeds of Accounts shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit.

(c) At the Administrative Agent’s request at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Administrative Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Accounts, including all original orders, invoices and shipping receipts.

(d) Upon the occurrence and during the continuance of an Event of Default, a Grantor shall not grant any extension of the time of payment of any of the Accounts, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any person liable for the payment thereof, or allow any credit or discount whatsoever thereon if the Administrative Agent shall have instructed the Grantors not to grant or make any

such extension, credit, discount, compromise, or settlement under any circumstances during the continuance of such Event of Default.

5.2. Communications with Obligors: Grantors Remain Liable. (a) The Administrative Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default, after giving reasonable notice to the relevant Grantor of its intent to do so, communicate with obligors under the Accounts to verify with them to the Administrative Agent’s satisfaction the existence, amount and terms of any Accounts. The Administrative Agent shall have the absolute right to share any information it gains from such inspection or verification with any Secured Party.

(b) Upon the written request of the Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on the Accounts that the Accounts have been assigned to the Administrative Agent for the ratable benefit of the Secured Parties and that payments in respect thereof shall be made directly to the Administrative Agent.

(c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of the Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the Administrative Agent nor any Secured Party shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this Security Agreement or the receipt by the Administrative Agent or any Secured Party of any payment relating thereto, nor shall the Administrative Agent or any Secured Party be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

5.3. Proceeds to be Turned Over To Administrative Agent. In addition to the rights of the Administrative Agent and the Secured Parties specified in Section 5.1 with respect to payments of Accounts, if an Event of Default shall occur and be continuing and the Administrative Agent so requires by notice in writing to the relevant Grantor (it being understood that the exercise of remedies by the Secured Parties in connection with an Event of Default under Section 11.5 of the Credit Agreement shall be deemed to constitute a request by the Administrative Agent for the purposes of this sentence and in such circumstances, no such written notice shall be required), all Proceeds received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the Administrative Agent and the Secured Parties, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Administrative Agent in the exact form received by such Grantor (duly endorsed by such Grantor to the Administrative Agent, if required). All Proceeds received by the Administrative Agent hereunder shall be held by the Administrative Agent in a Collateral Account maintained under its sole dominion and control and on terms and conditions reasonably satisfactory to the Administrative Agent. All Proceeds while held by the Administrative Agent in a Collateral Account (or by such Grantor in trust for the Administrative

Agent and the Secured Parties) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 5.5.

5.4. Application of Proceeds. The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral as well as any Collateral consisting of cash, at any time after receipt as follows:

5.5. Code and Other Remedies. If an Event of Default shall occur and be continuing, the Administrative Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the NY UCC or any other applicable law and also may without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange broker’s board or at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral. The Administrative Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Administrative Agent shall have the right

to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Administrative Agent or any Secured Party shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, and the Administrative Agent or such Secured Party may subject to (x) the satisfaction in full in cash of all payments due pursuant to Section 5.4(i), and (y) the ratable satisfaction of the Obligations in accordance with Section 5.4(ii), pay the purchase price by crediting the amount thereof against the Obligations. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, each Grantor hereby waives any claim against the Administrative Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Administrative Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Each Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at places which the Administrative Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.5 in accordance with the provisions of Section 5.4.

5.6. Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the fees and disbursements of any attorneys employed by the Administrative Agent or any Secured Party to collect such deficiency.

5.7. Amendments, etc. with Respect to the Obligations; Waiver of Rights. Each Grantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Grantor and without notice to or further assent by any Grantor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required

Lenders, as the case may be, or, in the case of any Hedge Agreement or documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Security Agreement or any property subject thereto. When making any demand hereunder against any Grantor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the US Borrower or any Grantor or grantor, and any failure by the Administrative Agent or any other Secured Party to make any such demand or to collect any payments from the US Borrower or any Grantor or grantor or any release of the US Borrower or any Grantor or grantor shall not relieve any Grantor in respect of which a demand or collection is not made or any Grantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Grantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

6. The Administrative Agent.

6.1. Administrative Agent’s Appointment as Attorney-in-Fact, etc. (a) Each Grantor hereby appoints, which appointment is irrevocable and coupled with an interest, effective upon and during the occurrence of an Event of Default, the Administrative Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Administrative Agent the power and right, on behalf of such Grantor, either in the Administrative Agent’s name or in the name of such Grantor or otherwise, without assent by such Grantor, to do any or all of the following, in each case after and during the occurrence of an Event of Default and after written notice by the Administrative Agent of its intent to do so:

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Administrative Agent may request to evidence the Administrative Agent’s and the Secured Parties’ Security Interest in such Intellectual Property and the

goodwill and general intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral;

(iv) execute, in connection with any sale provided for in Section 5.5, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral;

(vii) ask or demand for, collect and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral;

(xiii) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though

the Administrative Agent were the absolute owner thereof for all purposes, and do, at the Administrative Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things that the Administrative Agent deems necessary to protect, preserve or realize upon the Collateral and the Administrative Agent’s and the Secured Parties’ Security Interests therein and to effect the intent of this Security Agreement, all as fully and effectively as such Grantor might do.

6.2. Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the NY UCC or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property. Neither the Administrative Agent, any Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Administrative Agent and the Secured Parties hereunder are solely to protect the Administrative Agent’s and the Secured Parties’ interests in the Collateral and shall not impose any duty upon the Administrative Agent or any Secured Party to exercise any such powers. The Administrative Agent and the Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

6.3. Authority of Administrative Agent. Each Grantor acknowledges that the rights and responsibilities of the Administrative Agent under this Security Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between the Administrative Agent and the Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

6.4. Security Interest Absolute. All rights of the Administrative Agent hereunder, the security interest and all obligations of the Grantors hereunder shall be absolute and unconditional.

6.5. Continuing Security Interest; Assignments Under the Credit Agreement Release. (a) This Security Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Grantor and the successors and assigns thereof and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their respective successors, indorsees, transferees and assigns until all Obligations under the Credit Documents and the obligations of each Grantor under this Security Agreement shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. This Security Agreement and the security interest granted hereby shall terminate on the first date on which all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding.

(b) A Subsidiary Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Subsidiary Grantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Subsidiary Grantor ceases to be a Domestic Subsidiary of the US Borrower.

The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property.

11. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Administrative Agent and any nominee of the Administrative Agent may exercise in respect of all or any of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it and without the restrictions contained in section 21 of the Act, all the rights and remedies of the registered holder of the Collateral and all other powers conferred on mortgagees by section 24 of the Act (as hereby varied or extended) and may without notice, except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange broker’s board or at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral. The Administrative Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and,

upon consummation of any such sale, the Administrative Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, the Pledgor hereby waives any claim against the Administrative Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Administrative Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Section 25 of the Act shall not apply to this Pledge or to any security given pursuant hereto. Any third party referred to in this sub-Section (a) may enjoy the benefit or enforce the terms of this sub-Section (a) in accordance with the provisions of the Contracts (Rights of Third Parties) Act, Chapter 53B of Singapore.

Upon any sale of the Collateral by the Administrative Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Administrative Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Administrative Agent or such officer or be answerable in any way for the misapplication thereof. Any third party referred to in this sub-Section (b) may enjoy the benefit or enforce the terms of this sub-Section (b) in accordance with the provisions of the Contracts (Rights of Third Parties) Act, Chapter 53B of Singapore.

(d) All payments received by the Pledgor after the occurrence and during the continuance of an Event of Default in respect of the Collateral shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other property or funds of the Pledgor and shall be forthwith delivered to the Administrative Agent as Collateral in the same form as so received (with any necessary indorsement).

(e) The Pledgor and Administrative Agent agree and acknowledge that the Administrative Agent is entering into this Pledge, and holds its rights and benefits hereunder, as trustee for and on behalf of the Secured Parties.

or any property subject thereto.

The Pledgor hereby appoints, which appointment is irrevocable and coupled with an interest, the Administrative Agent as the Pledgor’s attorney, with full authority in the place and stead of the Pledgor and in the name of the Pledgor or otherwise to take any action and to execute any instrument, in each case after the occurrence and during the continuance of an Event of Default, that the Administrative Agent may deem reasonably necessary or advisable to accomplish the purposes of this Pledge Agreement, including to receive, indorse and collect all instruments made payable to the Pledgor

representing any dividend or distribution payment in respect of the Collateral or any part thereof and to give full discharge for the same.

10. The Administrative Agent’s Duties. The powers conferred on the Administrative Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Shares, whether or not the Administrative Agent or any other Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property.

11. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Administrative Agent and any nominee of the Administrative Agent may, on behalf of the Secured Parties, exercise in respect of all or any of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it all the rights and remedies of a pledgee under the law of the Republic of China. The Administrative Agent and any nominee of the Administrative Agent may, on behalf of the Secured Parties and with prior notice to the Pledgor, except as specified below, sell the Collateral or any part thereof at a public sale. To the extent permitted by the law of the Republic of China, the Administrative Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Administrative Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Administrative Agent or any Secured Party shall have the right upon any such public sale to purchase the whole or any part of the Collateral so sold, and the Administrative Agent or such Secured Party may subject to (x) the satisfaction in full in cash of all payments due pursuant to Section 11(b)(i), and (y) the ratable satisfaction of the Obligations in accordance with Section 11(b)(ii) pay the purchase price by crediting the amount thereof against the Obligations. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to the Pledgor of the time and place of any public sale shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, the Pledgor hereby waives any claim against the Administrative Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a public sale was less than the price that might have

been obtained through any other means of disposal of the Collateral, even if the Administrative Agent accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral at any time after receipt as follows:

(i) first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Pledge Agreement, the other Credit Documents or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of the Pledgor and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

(iii) third, any surplus then remaining shall be paid to the Pledgor or its successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

(c) The Administrative Agent may, on behalf of the Secured Parties, exercise any and all rights and remedies of the Pledgor in respect of the Collateral.

(d) All payments received by the Pledgor after the occurrence and during the continuance of an Event of Default in respect of the Collateral shall be received in trust for the benefit of the Administrative Agent and the other Secured Parties, shall be segregated from other property or funds of the Pledgor and shall be forthwith delivered to the Administrative Agent for the benefit of the Secured Parties as Collateral in the same form as so received (with any necessary indorsement).

(e) The Pledgor and Administrative Agent agree and acknowledge that the Administrative Agent is entering into this Pledge Agreement, and holds its rights and benefits hereunder, as trustee for and on behalf of the Secured Parties until the date this Pledge Agreement is released in accordance with its terms.

12. Amendments. etc. with Respect to the Obligations: Waiver of Rights. The Pledgor shall remain obligated hereunder, and the charges created hereby shall not be adversely

(b) Upon any sale or other transfer by the Pledgor of any Collateral that is permitted under the Credit Agreement to any person, or upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 14.1 of the Credit Agreement, the obligations of such Pledgor with respect to such Collateral shall be automatically released and such Collateral sold free and clear of the Lien created hereby.

17. Severability.

No failure to exercise, nor any delay in exercising, on the part of the

Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent or such other Secured Party would otherwise have on any future occasion.

(c) The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

20. Section Headings. The Section headings used in this Pledge Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

5.4 Non-violation: Each Charging Company further covenants and represents to the Administrative Agent that neither the execution and delivery of this Deed nor the performance of any of the covenants contained in it does or will contravene or constitute a default under (or result in the creation or imposition of, or the obligation to create or impose, any Lien upon any of its property or assets pursuant to), or cause to be exceeded any limitation on it or the powers of its directors imposed by or contained in:

5.4.1 any law by which it or any of its assets is bound or affected;

5.4.3 any agreement to which it is a party or by which any of its assets is bound.

Any moneys so expended by the Administrative Agent shall be repayable by such Charging Company to the Administrative Agent on demand together with interest at the rate specified in Section 2.8(c)(y) of the Credit Agreement from the date of payment by the Administrative Agent until such repayment, both before and after judgment. No exercise by the Administrative Agent of its powers under this clause 5.5 shall make the Administrative Agent or any other of the Secured Parties liable to account as a mortgagee or heritable creditor in possession.

8.1.1 first, to the amount of all moneys raised or borrowed by the Receiver, and all costs, charges, expenses and liabilities paid, incurred or charged by the Receiver (including any amounts for which he is entitled to be indemnified) in connection with or as a result of the exercise of his powers and the remuneration of the Receiver, in such order as the Receiver or the Administrative Agent may from time to time determine;

8.1.2 second, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection with such collection or sale or otherwise in connection with this Deed, the other Credit Documents or any of the Secured Amounts, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Credit Document on behalf of any Charging Company and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Credit Document;

8.1.3 third, to the Secured Parties, an amount equal to all Secured Amounts owing to them on the date of any such distribution, and, if such moneys shall be insufficient to pay such amounts in full, then rateably (without priority of any one over any other) to such Secured Parties in proportion to the unpaid amounts thereof; and

8.1.4 fourth, any surplus then remaining shall be paid to the Charging Companies or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

8.2 Accounts: Notwithstanding the provisions of clause 8.1, all moneys from time to time received by the Administrative Agent from any Charging Company or any Person or Persons liable to pay the same or from any Receiver or otherwise on the realisation or enforcement of the charges contained in this Deed may be applied by the Administrative Agent either as a whole or in such proportion as the Administrative Agent shall think fit to any account or item of account or any transaction and, without limitation, the Administrative Agent may in its absolute discretion at all times pending the payment to

the Administrative Agent of all of the Secured Amounts place and keep to the credit of a separate or suspense interest bearing account (subject to the accrual of interest at market rates for the account of the relevant Charging Company) any money received by the Administrative Agent from such Charging Company or such other Persons for so long and in such manner as the Administrative Agent may determine without any obligation to apply the same or any part thereof in or towards the discharge of any of the Secured Amounts.

10.2 Possession: Without prejudice to the generality of clause 10.1, entry into possession of the Charged Property shall not render the Administrative Agent or any Receiver liable to account as mortgagee or heritable creditor in possession; and if and whenever the Administrative Agent or any Receiver enters into possession of the Charged Property, it shall be entitled at any time to go out of such possession.

11. Expenses and indemnity

11.3 Taxes: All sums of whatsoever nature which are payable by any Charging Company under this Deed and which are now or at any time hereafter become subject to value added tax or any similar tax shall be deemed to be exclusive of value added tax or any similar tax and each Charging Company in addition to such sums will indemnify the Administrative Agent from and against all claims and liabilities whatsoever in respect thereof. Each Charging Company agrees to pay, and to indemnify the Administrative Agent, any Receiver and the Secured Parties against any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Charged Property or in connection with any of the transactions contemplated by this Deed.

12.1.1 to deposit with the Administrative Agent (which it may, subject to the terms of the Credit Agreement, retain during the continuance of the charges contained in this Deed) if the Administrative Agent so requires:

12.1.3 if the Administrative Agent so requires, promptly to execute a fixed mortgage or charge (as the Administrative Agent may require), on terms comparable (so far as reasonably possible) to the Liens intended to be created by this Deed of all or any part of the Charged Property which is for the time being subject to the floating charge contained in this Deed;

12.1.4 if the Administrative Agent so requires, promptly to execute an assignment to the Administrative Agent (on behalf of the Secured Parties) on terms comparable (so far as reasonably possible) to the Liens intended to be created by this Deed of all or any debts or moneys payable to such Charging Company and any Liens or documents relating to them or otherwise to negotiate the same to the Administrative Agent;

12.1.6 if the Administrative Agent so requires, promptly to execute a mortgage or first fixed charge if it acquires or agrees to acquire any intellectual property rights in terms specified by the Administrative Agent.

12.2 Further security: Each Charging Company further covenants with the Administrative Agent from time to time (and, for the purposes mentioned in clause 12.2.2, notwithstanding that the Administrative Agent may not have served a demand for payment of the Secured Amounts) upon demand to execute, at such Charging Company’s own cost, any document or do any act or thing which:

12.2.1 the Administrative Agent may reasonably specify with a view to perfecting or protecting any charge or security created or intended to be created by this Deed; or

12.2.2 the Administrative Agent or any Receiver may reasonably specify with a view to facilitating the exercise or the proposed exercise of any of their powers.

12.3 Registration: Each Charging Company covenants to procure that the legal mortgages contained in this Deed in respect of the Properties vested in it are registered against the registered title of any registered land hereby affected.

13. Crystallisation

13.1 Notice: In addition and without prejudice to any other event resulting in a crystallisation of the floating charge created by this Deed or any other right the Administrative Agent may have but subject to clause 13.4, the Administrative Agent may, at any time (subject to clause 13.2) after an Enforcement Event has occurred, by notice in writing to the relevant Charging Company declare that the floating charge hereby created shall be converted into a first specific fixed charge as to all of the undertaking, property and assets or such of them as may be specified in the notice, and by way of further assurance, such Charging Company, at its own expense, shall execute all documents in such form as the Administrative Agent shall require and shall deliver to the Administrative Agent all conveyances, deeds, certificates and documents which may be necessary to perfect the first specific fixed charge.

13.2 Demand: Before a demand for payment has been made, a notice may only be served by the Administrative Agent under clause 13.1 if the Administrative Agent has reason to believe that such Charging Company’s property, assets and rights described or referred to in the demand or notice are in danger of being seized or sold under any form of distress or execution levied or threatened or are otherwise in immediate jeopardy.

13.3 Automatic crystallisation: In addition and without prejudice to any other event resulting in a crystallisation of the floating charge but subject to clause 13.4, the floating charge contained herein shall automatically be converted into a fixed charge over all property, assets or undertaking of a Charging Company subject to the floating charge if and when the holder of any other Lien whether ranking in priority to or pad passu with or after the

charges contained in this Deed shall appoint an administrator, administrative receiver, receiver, manager or receiver and manager.

13.4 Insolvency Act 2000, void provisions: No floating charge granted by any Charging Company pursuant to clause 3.1.2 shall, either by notice given by the Administrative Agent under clause 13.1 or automatically under clause 13.3, be converted into fixed charges over any Charged Property or otherwise crystallise solely as a result of:

13.4.1 the obtaining of a moratorium by such Charging Company; or

14.3.1 exercise or procure that its nominees shall exercise all such rights and powers at the specific request of and in accordance with the instructions of such Charging Company but so that neither the Administrative Agent nor any nominees of the Administrative Agent shall be obliged to give effect to any request or instruction which the Administrative Agent may consider would be prejudicial to the charges contained in this Deed or if in doing so it would incur any cost or expense or render itself subject to any liability, unless previously indemnified to its satisfaction; and

14.3.2 pay or procure that its nominee shall pay to such Charging Company all dividends, interest and other distributions of an income nature that it or its nominee receives.

The Administrative Agent shall have the absolute right to share any information it gains from such inspection and review with any Secured Party.

16. Other security, etc.

16.1 No merger: The charges contained in or created pursuant to this Deed are in addition to, and shall neither be merged in, nor in any way exclude or prejudice any other Lien, right of recourse, set off or other right whatsoever which the Secured Parties may now or at any time hereafter hold or have (or would apart from this Deed or any charge contained or created pursuant to this Deed hold or have) as regards each Charging Company or any other Person in respect of the Secured Amounts and the Administrative Agent shall be

under no obligation to take any steps to call in or to enforce any security for the Secured Amounts and shall not be liable to any Charging Company for any loss arising from any omission on the part of the Administrative Agent to take any such steps or for the manner in which the Administrative Agent shall enforce or refrain from enforcing any such security.

16.2 Consolidation: Section 93 of the 1925 Act shall not apply in relation to any of the charges contained in this Deed.

16.3 Ruling off: Without prejudice to clause 5.1.1, if the Administrative Agent receives notice of any Lien or any other interest (other than an interest arising out of a sale in the usual course of business which is permitted by the Credit Documents) affecting the Charged Property:

16.3.1 the Administrative Agent may open a new account with the relevant Charging Company and, if it does not, it shall nevertheless be deemed to have done so at the time it received such notice; and

16.3.2 all payments made by such Charging Company to the Administrative Agent after the Administrative Agent receives such notice shall be credited or deemed to have been credited to the new account, and in no circumstances whatsoever shall operate to reduce the Secured Amounts as at the time the Administrative Agent received such notice.

16.4 Change of name, etc.: This Deed shall remain valid and enforceable notwithstanding any:

16.4.1 Incapacity, change in the name, composition or constitution of the Administrative Agent or any Charging Company or any amalgamation or consolidation by the Administrative Agent or any Charging Company with any other corporation; or

16.4.2 any amendment, waiver or variation (however material or fundamental) of any Credit Document.

Without prejudice to the foregoing, each Charging Company shall be deemed to be a principal debtor and the sole, original and independent obligor for the Secured Amounts and its Charged Property shall be deemed to be a principal security for the Secured Amounts. The liability of each Charging Company under this Deed shall not be discharged, impaired or otherwise affected by any circumstance, act, omission, matter or thing which but for this provision might operate to reduce, release, prejudice or otherwise exonerate any Charging Company from its obligations under the Credit Documents in whole or in part, including without limitation and whether or not known to any Credit Party, the Administrative Agent or any other Person:

(a) the winding-up, dissolution, administration, re-organisation, amalgamation, merger or reconstruction of any Charging Company or any other Person or any change in its status, function, control or ownership; or

(b) any time, indulgence, concession, waiver or consent granted to, or composition with, any Charging Company or any other Person; or

(c) the release of any Charging Company or any other Person under the terms of any composition or arrangement with any creditor of the such Charging Company or any of its Affiliates; or

(d) the taking, variation, compromise, exchange, renewal or release of, or refusal or neglect to perfect, take-up or enforce, any rights against, or security over, the assets of any Charging Company or any other Person or any non-presentation or non-observance of any formality or other requirement in respect of any instrument or any failure to release or to realise the full value of any security; or

(e) any legal limitation, disability, Incapacity or lack of power, authority or legal personality of or dissolution or change in the members or status of, or other circumstance relating to, any Charging Company or any other Person; or

(f) any variation (however fundamental and whether or not involving any increase in the liability of any Charging Company or any other Credit Party thereunder) or replacement of any Credit Document or any other document or security; or

(g) any unenforceability, illegality, invalidity or frustration of any obligation of any Charging Company or any other Person under any Credit Document or any other document or security, or any failure of any Charging Company or any other Credit Party to become bound by the terms of any other Credit Document, in each case whether through any want of power or authority or otherwise; or

(h) any postponement, discharge, reduction, non-provability or similar circumstances affecting any obligation of any Charging Company or any other Credit Party under a Credit Document resulting from any insolvency, liquidation or dissolution proceedings or from any law, regulation or order,

so that each Charging Company’s obligations under this Deed remain in full force and effect and that this Deed shall be construed accordingly as if there were no such circumstance, act, omission, matter or thing.

16.5 Non-competition: Subject as provided below, until the date on which all the Secured Amounts and the obligations of the Charging Companies under this Deed shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Secured Amounts), no Charging Company shall, by virtue of any payment made, security realised or moneys received or recovered under any of the Credit Documents for or on account of the liability of any Credit Party:

16.5.1 be subrogated to any rights, security or moneys held, received or receivable by the Administrative Agent or any other Secured Party or be entitled to any right of contribution or indemnity; or

16.5.2 claim, rank, prove or vote as a creditor of any Credit Party or its estate in competition with the Administrative Agent or any other Secured Party; or

16.5.3 receive, claim or have the benefit of any payment, distribution or security from or on account of any Credit Party, or exercise any right of set-off against any Credit Party.

Each Charging Company shall hold in trust for and forthwith pay or transfer to the Administrative Agent for the benefit of the Secured Parties any payment or distribution or benefit of security received by it contrary to the above. If any Charging Company exercises any right of set-off contrary to the above it will forthwith pay an amount equal to the amount set off to the Administrative Agent for the benefit of the Secured Parties. Notwithstanding the foregoing, following any enforcement of the security created hereunder by the Administrative Agent under this Deed, each Charging Company will (at its own cost) promptly take such steps or actions as are referred to above as the Administrative Agent may from time to time stipulate.

17. Set-off

Each Secured Party may upon the occurrence of an Enforcement Event and notwithstanding any settlement of account or other matter whatsoever combine or consolidate all or any of its existing accounts including accounts in the name of such Secured Party or of any Charging Company jointly with others and may set off or transfer all or any part of any credit balance or any sum standing to the credit of any account (whether or not the same is due to such Charging Company from such Secured Party and whether or not the credit balance and the account in debit or the Secured Amounts are expressed in the same currency in which case such Secured Party is hereby authorised to effect any necessary conversions at its then prevailing rates of exchange) in or towards satisfaction of any of the Secured Amounts and may in its absolute discretion (acting reasonably) estimate the amount of any liability of such Charging Company which is contingent or unascertained and thereafter set off such estimated amount and no amount shall be payable by such Secured Party to such Charging Company unless and until all Secured Amounts have been ascertained and fully repaid or discharged.

18. Avoidance of payments

18.1 No release: No assurance, security or payment which may be avoided or adjusted under the law, including under any enactment relating to bankruptcy or insolvency, and no release, settlement or discharge given or made by the Administrative Agent on the faith of any such assurance, security or payment, shall prejudice or affect the right of the Administrative Agent to recover the Secured Amounts from any Charging Company (including any moneys which it may be compelled to pay or refund under the provisions of the Insolvency Act and any costs payable by it pursuant to or otherwise incurred in connection therewith) or to enforce the charges contained in this Deed to the full extent of the Secured Amounts.

18.2 Retention of charges: If the Administrative Agent shall have reasonable grounds in its absolute discretion for believing that any Charging Company may be insolvent or deemed to be insolvent pursuant to the provisions of the Insolvency Act as at the date of any payment made by such Charging Company to the Administrative Agent, the Administrative Agent shall be at liberty to retain the charges contained in or created

pursuant to this Deed until the expiry of a period of one month plus such statutory period within which any assurance, security, guarantee or payment can be avoided or invalidated after the payment and discharge in full of all Secured Amounts notwithstanding any release, settlement, discharge or arrangement which may be given or made by the Administrative Agent on, or as a consequence of, such payment or discharge of liability provided that, if at any time within such period, a petition shall be presented to a competent court for an order for the winding up or the making of an administration order in respect of such Charging Company, or such Charging Company shall commence to be wound up or to go into administration or any analogous proceedings shall be commenced by or against such Charging Company, the Administrative Agent shall be at liberty to continue to retain such security for such further period as the Administrative Agent may determine and such security shall be deemed to continue to have been held as security for the payment and discharge to the Administrative Agent of all Secured Amounts.

19. Currency conversion

19.1 Indemnity: If under any applicable law, whether as a result of a judgment against any Charging Company or the liquidation of any Charging Company or for any other reason, any payment under or in connection with this Deed is made or any amount is received or recovered by the Administrative Agent in respect of the Secured Amounts in a currency (the “other currency”) other than the currency in which the Secured Amounts are payable (the “original currency”), then to the extent that the payment to or receipt by the Administrative Agent (when converted at the rate of exchange on the date of payment or receipt) falls short of the whole of the Secured Amounts the relevant Charging Company shall as a separate and independent obligation fully indemnify the Administrative Agent against the amount of the shortfall; and for the purposes of this clause, “rate of exchange” means the rate at which the Administrative Agent is able on the relevant date to purchase the original currency in London with the other currency.

19.2 Purchases: If any Charging Company fails to pay or discharge any part of the Secured Amounts when due (except where such payment or discharge is made within three Business Days of the due date), the Administrative Agent from time to time may purchase an amount of the currency in which such sum is due with any other currency or currencies and such Charging Company’s obligation thereafter shall be to pay to the Administrative Agent the amount of the other currency or currencies so used to purchase.

20. Declaration of Trust

20.1 Declaration of Trust: The Administrative Agent hereby declares itself as trustee to hold the benefit of the covenants, agreements and undertakings of each of the Charging Companies contained in this Deed and the Liens and other rights, titles and interests constituted by this Deed and all other moneys, property and assets paid to it or held by it or received or recovered by it pursuant to or in connection with this Deed with effect from the date of this Deed on trust for the Secured Parties for application in accordance with clause 8.1.

20.2 Perpetuity period: The trusts constituted or evidenced in or by clause 20.1 shall remain in full force and effect until whichever is the earlier of:

20.2.1 the expiration of a period of 80 years from the date of this Deed; and

20.2.2 the security constituted by this Deed having been released in accordance with its terms, and the parties to this Deed declare that the perpetuity period applicable to this Deed shall for the purposes of the Perpetuities and Accumulations Act 1964 be the period of 80 years from the date of this Deed.

23.2 Rights cumulative, waiver: The rights of the Administrative Agent and any Receiver are cumulative, may be exercised as often as they consider appropriate and are in addition to their respective rights under general law (including the right to appoint an administrator under the Insolvency Act). The respective rights of the Administrative Agent and any Receiver (whether arising under this Deed or under the general law) shall not be capable of being waived or varied otherwise than by express waiver or variation in writing; and, in particular, any failure to exercise or any delay in exercising any such rights shall not operate as a variation or waiver of that or any other such right; any defective or partial exercise of such rights shall not preclude any other or further exercise of that or any other such right; and no act or course of conduct or negotiation on their part or on their behalf shall in any way preclude them from exercising any such right or constitute a suspension or variation of any such right.

23.3 Invalidity of any provision: If any provisions of this Deed become invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired.

23.4 No set-off or counterclaim; payments free and clear: All payments to be made by a Charging Company under this Deed shall be made in full, without any set-off or counterclaim whatsoever and free and clear of any deductions or withholdings in the currency in which they are due on the due date to such account as the Administrative Agent may from time to time specify.

23.5 Liabilities survive deficiencies and releases: Each Charging Company agrees to be bound by this Deed notwithstanding that any other Person intended to execute or to be bound by this Deed or any other Credit Document may not do so or may not be effectually bound and notwithstanding that any guarantees or Liens contained in any other Credit Document may be terminated or released or may be or become invalid or unenforceable, whether or not the deficiency is known to any of the Secured Parties.

23.6 Law of Property (Miscellaneous Provisions) Act 1989: For the purposes of the Law of Property (Miscellaneous Provisions) Act 1989 any provisions of the Credit Documents relating to any disposition of an interest in land shall be deemed to be incorporated in this Deed.

23.7 Contracts (Rights of Third Parties) Act 1999: Without prejudice to clause 8.1, and save for clauses 10.1, 11.2 and 17, no provision of this Deed is enforceable by a Person who is not a party to this Deed.

23.8.1 any and all restrictions on the transfer of its shares; or 23.8.2 any and all liens on shares, whether fully or partly paid.

23.9 Charge over Shares: The UK Borrower hereby irrevocably accepts its appointment under clause 21.8 of each UK Pledge Agreement as process agent in England for the US Borrower and hereby agrees that it will not revoke such appointment without the prior written consent of the Administrative Agent which consent shall not be unreasonably withheld or delayed.

Administrative Agent or any other Secured Party from the UK Borrower, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder, which shall, notwithstanding any such payment or payments other than payments made by such Guarantor in respect of the Obligations or payments received or collected from such Guarantor in respect of the Obligations, remain liable for the Obligations up to the maximum liability of such Guarantor hereunder until the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letters of Credit drawn by the UK Borrower shall be outstanding.

5. No Subrogation. Notwithstanding any payment or payments made by any of the Guarantors hereunder or any set-off or appropriation and application of funds of any of the Guarantors by the Administrative Agent or any other Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Party against the UK Borrower or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any other Secured Party for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or

If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Administrative Agent and the other Secured Parties, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether due or to become due, in such order as the Administrative Agent may determine.

6. Amendments, etc. with Respect to the Obligations; Waiver of Rights. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement or documents entered into with the Administrative Agent or any of its Affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any Guarantor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the UK Borrower or any Guarantor or guarantor, and any failure by the Administrative Agent or any other Secured Party to make any such demand or to collect any payments from the UK Borrower or any Guarantor or guarantor or any release of the UK Borrower or such Guarantor or guarantor shall not relieve any Guarantor in respect of which a demand or collection is not made or any Guarantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Guarantor. For the purposes hereof, “demand” shall include the commencement and continuance of any legal proceedings.

7. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, contraction, incurrence, renewal, extension, amendment, waiver or accrual of any of the Obligations, and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee, the Obligations or any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended, waived or accrued, in reliance upon this Guarantee; and all dealings between the UK Borrower and any of the Guarantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the UK Borrower or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, regularity or enforceability of the Credit Agreement, any other Credit Document, any Letter of Credit or any Hedge Agreement, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Administrative Agent or any other Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to or be asserted by the UK Borrower against the Administrative Agent or any other Secured Party or (c) any other circumstance whatsoever (with or without notice to or knowledge of the UK Borrower or such Guarantor) that constitutes, or might be construed to constitute, an equitable or legal discharge of the UK Borrower for the Obligations, or of such Guarantor under this Guarantee, in bankruptcy, liquidation, administration, or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent and any other Secured Party may, but shall be under no obligation to, pursue such rights and remedies as it may have against the UK Borrower or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any other Secured Party to pursue such other rights or remedies or to collect any payments from the UK Borrower or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the UK Borrower or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent and the other Secured Parties against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the other Secured Parties, and their respective successors, indorsees, transferees and assigns, until all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit drawn by the UK Borrower shall be outstanding, notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. A Guarantor shall automatically be released from its obligations hereunder and the Guarantee of such Guarantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Guarantor ceases to be a Subsidiary of the UK Borrower. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall

reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 7 shall be without recourse to or warranty by the Administrative Agent.

8. Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the UK Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the UK Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

9. Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in Dollars at the Administrative Agent’s Office.

10. Representations and Warranties; Covenants.

(b) Each Guarantor hereby covenants and agrees with the Administrative Agent and each other Secured Party that, from and after the date of this Guarantee until the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letter of Credit drawn by the UK Borrower remains outstanding, such Guarantor shall take, or shall refrain from taking, as the case may be, all actions that are necessary to be taken or not taken so that no violation of any provision, covenant or agreement contained in Section 9 or 10 of the Credit Agreement, and so that no Default or Event of Default, is caused by any act or failure to act of such Guarantor or any of its Subsidiaries.

11. Authority of Agent. Each Guarantor acknowledges that the rights and responsibilities of the Administrative Agent under this Guarantee with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Guarantee shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and such Guarantor, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

12. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 14.2 of the Credit Agreement. All communications and notices

hereunder to each Guarantor shall be given to it in care of the UK Borrower at the UK Borrower’s address set forth in Section 14.2 of the Credit Agreement.

16. Amendments in Writing; No Waiver; Cumulative Remedies.

(c) The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

20. WAIVER OF JURY TRIAL. EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS GUARANTEE, ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

21. Submission to Jurisdiction; Waivers. Each Guarantor hereby irrevocably and unconditionally:

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Guarantor at its address referred to in Section 12 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

14.3 Ruling off: Without prejudice to clause 5.1.1, if the Administrative Agent receives notice of any Lien or any other interest (other than an interest arising out of a sale in the usual course of business which is permitted by Section 10.4 of the Credit Agreement) affecting the Charged Property:

14.3.1 the Administrative Agent may open a new account with the relevant Chargor and, if it does not, it shall nevertheless be deemed to have done so at the time it received such notice; and

14.3.2 all payments made by the Chargor to the Administrative Agent after the Administrative Agent receives such notice shall be credited or deemed to have been credited to the new account, and in no circumstances whatsoever shall operate to reduce the Secured Amounts as at the time the Administrative Agent received such notice.

Without prejudice to the foregoing, the Chargor shall be deemed to be a principal debtor and the sole, original and independent obligor for the Secured Amounts and the Charged Property shall be deemed to be a principal security for the Secured Amounts. The liability of the Chargor under this Deed shall not be discharged, impaired or otherwise affected by any circumstance, act, omission, matter or thing which but for this provision might operate to reduce, release, prejudice or otherwise exonerate the Chargor from its obligations under the Credit Documents in whole or in part, including without limitation and whether or not known to any Credit Party, the Administrative Agent or any other Person:

(a) the winding-up, dissolution, administration, re-organisation, amalgamation, merger or reconstruction of the Chargor or any other Person or any change in its status, function, control or ownership; or

(b) any time, indulgence, concession, waiver or consent granted to, or composition with, the Chargor or any other Person; or

(c) the release of the Chargor or any other Person under the terms of any composition or arrangement with any creditor of the Chargor or any of its Affiliates; or

(d) the taking, variation, compromise, exchange, renewal or release of, or refusal or neglect to perfect, take-up or enforce, any rights against, or security over, the assets of the Chargor or any other Person or any non-presentation or non-observance of any formality or other requirement in respect of any instrument or any failure to release or to realise the full value of any security; or

(f) any variation (however fundamental and whether or not involving any increase in the liability of the Chargor or any other Credit Party thereunder) or replacement of any Credit Document or any other document or security; or

(g) any unenforceability, illegality, invalidity or frustration of any obligation of the Chargor or any other Person under any Credit Document or any other document or security, or any failure of the Chargor or any other Credit Party to become bound by the terms of any other Credit Document, in each case whether through any want of power or authority or otherwise; or

(h) any postponement, discharge, reduction, non-provability or similar circumstances affecting any obligation of the Chargor or any other Credit Party under a Credit

Document resulting from any insolvency, liquidation or dissolution proceedings or from any law, regulation or order,

so that the Chargor’s obligations under this Deed remain in full force and effect and that this Deed shall be construed accordingly as if there were no such circumstance, act, omission, matter or thing.

14.5 Non-competition: Subject as provided below, until the date on which all the Secured Amounts and the obligations of the Chargor under this Deed shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Secured Amounts), the Chargor shall not, by virtue of any payment made, security realised or moneys received or recovered under any of the Credit Documents for or on account of the liability of any Credit Party:

14.5.1 be subrogated to any rights, security or moneys held, received or receivable by the Administrative Agent or any other Secured Party or be entitled to any right of contribution or indemnity; or

14.5.2 claim, rank, prove or vote as a creditor of any Credit Party or its estate in competition with the Administrative Agent or any other Secured Party; or

14.5.3 receive, claim or have the benefit of any payment, distribution or security from or on account of any Credit Party, or exercise any right of set-off against any Credit Party.

The Chargor shall hold in trust for and forthwith pay or transfer to the Administrative Agent for the benefit of the Secured Parties any payment or distribution or benefit of security received by it contrary to the above. If the Chargor exercises any right of set-off contrary to the above it will forthwith pay an amount equal to the amount set off to the Administrative Agent for the benefit of the Secured Parties. Notwithstanding the foregoing, following any enforcement of the security created hereunder by the Administrative Agent under this Deed, the Chargor will (at its own cost) promptly take such steps or actions as are referred to above as the Administrative Agent may from time to time stipulate.

15. Avoidance of payments

15.1 No release: No assurance, security or payment which may be avoided or adjusted under the law, including under any enactment relating to bankruptcy or insolvency, and no release, settlement or discharge given or made by the Administrative Agent on the faith of any such assurance, security or payment, shall prejudice or affect the right of the Administrative Agent to recover the Secured Amounts from the Chargor (including any moneys which it may be compelled to pay or refund under the provisions of the Insolvency Act 1986 and any costs payable by it pursuant to or otherwise incurred in connection therewith) or to enforce the charges contained in this Deed to the full extent of the Secured Amounts.

to hear and determine any suit, action or proceeding, and to settle any dispute, which may arise out of or in connection with this Deed and agrees not to claim that any such court is not a convenient or appropriate forum.

22.3 Other competent jurisdictions: The submission to the jurisdiction of the courts referred to in clause 22.1 shall not (and shall not be construed so as to) limit the right of the Administrative Agent to take proceedings against the Chargor in any other court of competent jurisdiction nor shall the taking of proceedings in any one or more jurisdictions preclude the taking of proceedings in any other jurisdiction, whether concurrently or not.

22.4 Consent to enforcement: The Chargor hereby consents generally in respect of any legal action or proceeding arising out of or in connection with this Deed to the giving of any relief or the issue of any process in connection with such action or proceeding including, without limitation, the making, enforcement or execution against any property whatsoever of the Chargor (irrespective of its use or intended use) of any order or judgment which may be made or given in such action or proceeding.
