to Eurodollar Tranches. Each prepayment of the Loans under this Section 2.09 shall be accompanied by accrued interest to the extent required by Section 2.11 and any break funding costs pursuant to Section 2.14.

 (d) All prepayments of Loans pursuant to this Section 2.09 shall be without the payment by the Borrower of any premium or
penalty except for break funding costs payable pursuant to Section 2.14. 
 Section 2.10 Fees. (a) The Borrower
agrees to pay to the Administrative Agent (or its Affiliates), for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent (or its Affiliates). 
 (b) All fees payable hereunder shall be paid in dollars on the dates due, in immediately available funds, to the Administrative Agent for distribution to
the Lenders (as applicable). Fees paid shall not be refundable under any circumstances, except to the extent expressly provided to the contrary in a separate written agreement between the Borrower and the Administrative Agent (or its Affiliates).

  

 20 








 Section 2.11 Interest. (a) The portion of each Loan comprising each ABR Tranche shall
bear interest at the Alternate Base Rate plus the Applicable Rate. 
 (b) The portion of each Loan comprising each Eurodollar Tranche shall
bear interest at the LIBO Rate for the Interest Period in effect for such Tranche plus the Applicable Rate. 
 (c) Notwithstanding the
foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as
well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any
other amount, 2% plus the rate applicable to ABR Tranches as provided in paragraph (a) of this Section. 
 (d) Accrued interest on each
Tranche shall be payable in arrears on each Interest Payment Date for such Tranche; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Tranche (other than a prepayment of an ABR Tranche prior to the Maturity Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of
any conversion of any Eurodollar Tranche prior to the end of the current Interest Period therefor, accrued interest on such Tranche shall be payable on the effective date of such conversion. 
 (e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at
times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but
excluding the last day). The applicable Alternate Base Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 
 Section 2.12 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Tranche: 
 (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist
for ascertaining the LIBO Rate for such Interest Period; or 
 (b) the Administrative Agent is advised by the Required Lenders that the LIBO
Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining the portion of their Loans (or its Loan) included in such Tranche for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or facsimile as promptly as practicable thereafter and, until the
Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Tranche to, or 

  

 21 








 
continuation of any Tranche as, a Eurodollar Tranche shall be ineffective, and (ii) if the Borrowing Request requests a Eurodollar Tranche, such Tranche
shall be made as an ABR Tranche; provided that if the circumstances giving rise to such notice affect only one Type of Tranche, then the other Type of Tranche shall be permitted. 
 Section 2.13 Increased Costs. (a) If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or
credit extended by, any Lender; or 
 (ii) impose on any Lender or the London interbank market any other condition affecting this Agreement
or Eurodollar Tranches comprising the Loan made by such Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of
making or maintaining any portion of its Loan comprising a Eurodollar Tranche (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or to reduce the amount of any sum received or receivable by such Lender
hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
 (b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such
Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loan made by such Lender to a level below that which such Lender or such Lender’s holding company could have
achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such
additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered. 
 (c) A
certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall
be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 (d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower
shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above
shall be extended to include the period of retroactive effect thereof. 
  

 22 








 Section 2.14 Break Funding Payments. In the event of (a) the payment of any principal of
any Eurodollar Tranche other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Tranche other than on the last day of the Interest Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Tranche on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Tranche other than on the last day of the
Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.17, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the
case of a Eurodollar Tranche, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of
its Loan had such event not occurred, at the LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow,
convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it
to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 Section 2.15 Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear
of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) The Borrower shall indemnify the Administrative Agent and each Lender within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed
or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error. 
  

 23 








 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a
Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence
of such payment reasonably satisfactory to the Administrative Agent. 
 (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without
withholding or at a reduced rate. 
 (f) If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a
refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.15, it shall pay over such refund to the Borrower (but
only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.15 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the
Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such
Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such
Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it
deems confidential) to the Borrower or any other Person. 
 Section 2.16 Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise) prior to 12:00
noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at One Liberty Plaza, New York, New York 10006-1404, except that payments pursuant to
Section 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the
appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars. 
  

 24 








 (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay
fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. 
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
its Loan resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loan and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall
purchase (for cash at face value) participations in the Loans to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the
extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment
obtained by a Lender as consideration for the assignment of or sale of a participation in its Loan to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall
apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of
set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower
will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date
such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on
interbank compensation. 
 (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.16(d)
or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s
obligations under such Sections until all such unsatisfied obligations are fully paid. 
  

 25 








 Section 2.17 Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests
compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use
reasonable efforts to designate a different lending office for funding or booking its Loan hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and
would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b) If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any Lender defaults in its obligation to fund its Loan hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and
the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loan, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under
Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 
 ARTICLE III 
 Representations and Warranties 
 The Borrower represents and warrants to the Lenders that, as of the Effective Date:

 Section 3.02 Authorization; Enforceability. The Transactions are within the Borrower’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action. This Agreement has been
duly executed and delivered by the 

  

 26 








 
Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
 Section 3.03 Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or
filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational
documents of the Borrower or any of its Subsidiaries or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any of its Subsidiaries
or its assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Subsidiaries, and (d) will not result in the creation or imposition of any material Lien on any asset of the Borrower or any of
its Subsidiaries. 
 Section 3.04 Financial Condition; No Material Adverse Change. (a) The Borrower has heretofore furnished
to the Lenders (i) the audited consolidated balance sheet and related statements of income, stockholders equity and cash flows of the Borrower and its Subsidiaries as of and for the fiscal years ended December 31, 2006 and 2007, reported

and cash flows for the Borrower and its Subsidiaries and for the Targets and their respective subsidiaries for each fiscal quarter ending after December 31, 2007 (except for any quarter ending less than 45 days prior to the Effective Date),
certified, in each case, by its chief financial officer. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its consolidated Subsidiaries and of the
Targets and their respective consolidated subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year end audit adjustments and the absence of footnotes in the case of the statements referred to in clause
(iii) above. 
 (b) Since December 31, 2007, there has been no material adverse change in the business, assets, operations or
condition, financial or otherwise, of the Borrower and its Subsidiaries, taken as a whole. 
 Section 3.05 Properties.
(a) Each of the Borrower and its Subsidiaries has good title to, or valid leasehold interests in, all its real and personal properties that are Material, except for minor defects in title that do not interfere with its ability to conduct its
business as currently conducted or to utilize such properties for their intended purposes. 
 (b) Each of the Borrower and its Subsidiaries
owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property that are Material, and the use thereof by the Borrower and its Subsidiaries does not infringe upon the rights of any other Person, except
for any such infringements that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. 
  

 27 








 Section 3.06 Litigation and Environmental Matters. (a) There are no actions, suits or
proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any of its Subsidiaries (i) as to which there is a reasonable possibility of
an adverse determination and that, if adversely determined, would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) related to this Agreement. 

(b) Except for the Disclosed Matters and except with respect to any other matters that, individually or in the aggregate, would not reasonably be
expected to result in a Material Adverse Effect, neither the Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any
Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability. 
 Section 3.07 Compliance with Laws and Agreements. Each of the Borrower and its Subsidiaries is in compliance with all laws, regulations and
orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, would not reasonably be
expected to result in a Material Adverse Effect. No Default has occurred and is continuing. 
 Section 3.08 Investment Company
Status. Neither the Borrower nor any of its Subsidiaries is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940. 
 Section 3.09 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all Tax returns and reports required to
have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as applicable, has
set aside on its books adequate reserves or (b) to the extent that the failure to do so would not reasonably be expected to result in a Material Adverse Effect. 
 Section 3.10 ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, would
reasonably be expected to result in a Material Adverse Effect. The postretirement benefit obligations (determined as of the last day of the Borrower’s most recently ended fiscal year in accordance with Financial Accounting Standards Board
Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Borrower and its Subsidiaries have been determined in accordance with GAAP and are reflected in the applicable
footnotes of the Borrower’s and the Targets’ respective audited financial statements for their respective most recently ended fiscal year. 
  

 28 








 Section 3.11 Disclosure. The Borrower has disclosed to the Lenders all matters know to it,
that, individually or in the aggregate, would reasonably be expected to result in a Material Adverse Effect. None of the reports, financial statements, certificates or other information prepared by Borrower or at Borrower’s instruction and in
either case furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial
information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. 
 Section 3.12 Organization and Ownership of Subsidiaries; Affiliates. (a) Schedule 3.12 contains (except as noted therein) complete and correct lists (i) of the Borrower’s
Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Borrower and each
other Subsidiary, (ii) of the Borrower’s Affiliates, other than Subsidiaries, and (iii) of the Borrower’s directors and senior officers. 
 (b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown on Schedule 3.12 as being owned by the Borrower and its Subsidiaries have been validly issued, are fully
paid and nonassessable and are owned by the Borrower or another Subsidiary free and clear of any Lien (except as otherwise disclosed on Schedule 3.12). 
 (c) Schedule 3.12 sets forth all contractual provisions limiting the ability of each Subsidiary to make dividend payments to the Borrower. No Subsidiary is a party to, or otherwise subject to any legal,
regulatory, contractual or other restriction (other than this Agreement, the agreements listed on Schedule 3.12 and customary limitations imposed by corporate law or utility regulatory or similar statutes) that would restrict such
Subsidiary’s ability to pay dividends out of profits or make any other similar distributions of profits to the Borrower or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Subsidiary in
an amount substantially inconsistent with the past practice of such Subsidiary. 
 Section 3.13 Existing Funded Indebtedness.
Except as described therein, Schedules 4.01(e)(i) and 4.01(e)(ii) set forth a complete and correct list of all outstanding Funded Indebtedness of the Borrower and its Subsidiaries (exclusive of Capital Leases) as of December 31,
2007 (including a description of the obligors, principal amount outstanding and collateral therefor, if any, and any Guaranty in respect thereof), since which date there has been no Material change in the amounts, interest rates, sinking funds,
installment payments or maturities of the Funded Indebtedness of the Borrower or its Subsidiaries. Neither the Borrower nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on
any Funded Indebtedness of the Borrower or such Subsidiary and no event or condition exists with respect to any Funded Indebtedness of the Borrower or any Subsidiary with an outstanding principal amount in excess of $1,000,000 that would permit (or
that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Funded Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment. 
  

 29

become due, or to require the prepayment, repurchase, redemption or defeasance thereof, prior to its scheduled maturity; provided that this clause (g) shall not apply to secured Indebtedness that becomes due as a result of the voluntary
sale or transfer of the property or assets securing such Indebtedness; 
 (h) an involuntary proceeding shall be commenced or an involuntary
petition shall be filed seeking (i) liquidation, reorganization or other relief in respect of the Borrower or any of its material Subsidiaries or its debts, or of a substantial part of its assets, under any Federal, state or foreign bankruptcy,
insolvency, receivership or similar law now or hereafter in effect or (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any of its material Subsidiaries or for a
substantial part of its assets, and, in any such case, such proceeding or petition shall continue undismissed for sixty (60) days or an order or decree approving or ordering any of the foregoing shall be entered; 
 (i) the Borrower or any of its material Subsidiaries shall (i) voluntarily commence any proceeding or file any petition seeking liquidation,
reorganization or other relief under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any
proceeding or petition described in clause (h) of this Article, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any of its material
Subsidiaries or for a substantial part of its assets, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors or
(vi) take any action for the purpose of effecting any of the foregoing; 
 (j) the Borrower or any of its material Subsidiaries shall
become unable, admit in writing its inability or fail generally to pay its debts as they become due; 
 (k) one or more final judgments for
the payment of money in an aggregate amount in excess of $10,000,000 shall be rendered against the Borrower, any Subsidiary or any combination thereof and the same shall remain undischarged for a period of sixty (60) consecutive days during
which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any assets of the Borrower or any Subsidiary to enforce any such judgment; or 
 (l) a Change in Control shall occur; 
 then, and in every
such event (other than an event with respect to the Borrower described in clause (h) or (i) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Required
Lenders shall, by notice to the Borrower declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and
thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued 

  

 42 








 
hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the
Borrower; and in case of any event with respect to the Borrower described in clause (h) or (i) of this Article, the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the
Borrower accrued hereunder, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower. 
 ARTICLE VIII 
 The Administrative Agent 
 Each of the Lenders hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its
behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. 
 The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as
if it were not the Administrative Agent hereunder. 
 The Administrative Agent shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing,
(b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to
exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth
in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 
  

 43 








 The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying
upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it
orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants
and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply
to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities
as Administrative Agent. 
 Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the
Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been
so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a
successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as
Administrative Agent. 
 Each Lender acknowledges 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 credit analysis and decision to enter into this Agreement. Each Lender also acknowledges 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 from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related
agreement or any document furnished hereunder or thereunder.

 (iii) if to any other Lender, to it at its address (or facsimile number) set forth in its Administrative
Questionnaire. 
 (b) Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications
pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Lender. The
Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be
limited to particular notices or communications. 
 (c) Any party hereto may change its address or facsimile number for notices and other
communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. 

Section 9.02 Waivers; Amendments. (a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power
hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the
exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this
Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice
or knowledge of such Default at the time. 
 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall
(i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of
each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the
scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner that would alter the pro rata sharing of payments required
thereby, without the written consent of each Lender, or (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to
waive, amend or 

  

 46 








 
modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided
further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent. 
 Section 9.03 Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out of pocket expenses incurred by
the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated) and (ii) all out-of-pocket expenses incurred by the
Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including
its rights under this Section, or in connection with the Loans made issued hereunder, including all such out-of pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans. 
 (b) The Borrower shall indemnify the Administrative Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being
called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the
performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or
alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any
actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Indemnitee or from the breach in bad faith by such Indemnitee of its obligations hereunder. 
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, such
Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. 
  

 47 








 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any
claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or
instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof. 
 (e) Without the prior written consent of
the Administrative Agent and the applicable Indemnitees, neither the Borrower nor any of its Subsidiaries or Affiliates will settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding in
respect of which indemnification has been or could be sought under the indemnification provisions hereof (whether or not any Indemnitee is an actual or potential party to such claim, action or proceeding), unless such settlement, compromise or
consent (i) includes an unconditional written release, in form and substance reasonably satisfactory to the Indemnitees, of each Indemnitee from all liability arising out of such claim, action or proceeding and (b) does not include any
statement as to or an admission of fault, culpability or failure to act by or on behalf of any Indemnitee. 
 (f) In the event that any
Indemnitee is requested or required to appear as a witness in any action brought by or on behalf of or against the Borrower or any of its Subsidiaries or Affiliates in which such Indemnitee is not named as a defendant, the Borrower agrees to
reimburse such Indemnitee for all expenses incurred by it in connection with such Indemnitee’s appearing and preparing to appear as such a witness, including, without limitation, the fees and expenses of its legal counsel. 
 (g) Each Indemnitee agrees that promptly after its receipt of any service of any complaint or of the commencement of any action, claim, suit,
investigation or proceeding, or notice in respect of any of the foregoing, with respect to which indemnification is being sought hereunder, such Indemnitee will notify the Borrower in writing (to the extent legally permitted to do so) of such
complaint, of the commencement of such action or proceeding, or the receipt of such notice, but failure to so notify the Borrower will only relieve the Borrower from its obligation to indemnify any Indemnitee pursuant to this subsection if and to
the extent such failure results in the forfeiture by the Borrower or its Subsidiaries of any substantial right or defense. 
 (h) All amounts
due under this Section shall be payable promptly, but not later than ten (10) days, after written demand therefor. 
 Section 9.04
Successors and Assigns. (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, except that (i) the 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 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, 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 and the
Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
  

 48 








 (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 Loan) with the prior written consent (such consent not to be unreasonably withheld) of: 
 (A) the Borrower; provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved
Fund or, if an Event of Default has occurred and is continuing, any other assignee; and 
 (B) the Administrative Agent; provided
that no consent of the Administrative Agent shall be required for an assignment of any Loan (or portion thereof) 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 or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Loan, the amount of the Loan of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative
Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default 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; 
 (C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and
recordation fee of $3,500; and 
 (D) the assignee, if it shall not be a Lender prior to the time of such assignment, shall deliver to the
Administrative Agent an Administrative Questionnaire. 
 For the purposes of this Section 9.04(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)(iv) of this Section, from and after the effective date specified in each Assignment and 

  

 49 








 
Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption 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 2.13, 2.14,
2.15 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 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 Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the principal amount of the
Loan 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 Borrower, the Administrative Agent 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 Borrower and 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 Assumption
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 Assumption and record the information contained therein in the Register; provided
that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.16(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such
Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. 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 Borrower or
the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Loan);
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
Borrower, the Administrative Agent 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; 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 

  

 50 








 
waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 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 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though
it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15
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 Borrower’s prior written consent. A Participant
that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 2.15(e) as though it were a Lender. 
 (d) Any Lender may 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 without limitation 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. 
 Section 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower
herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement
and the making of the Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid.
The provisions of Sections 2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the
Loans or the termination of this Agreement or any provision hereof. 
 Section 9.06 Counterparts; Integration; Effectiveness.
This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received
counterparts hereof which, when taken together, bear 

  

 51 








 
the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement. 
 Section 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a
particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
 Section 9.08 Right of Setoff. If an
Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are
in addition to other rights and remedies (including other rights of setoff) which such Lender may have. 
 Section 9.09 Governing
Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York. 
 (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United
States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction. 
 (c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
  

 52
