Exhibit 4

Section1.5Interest Rates; LIBOR Notification. The interest rate on Loans is determined by reference to the LIBO Rate, which is derived from the London interbank offered rate. The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. In July 2017, the U.K. Financial Conduct Authority announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions to the ICE Benchmark Administration (together with any successor to the ICE Benchmark Administrator, the “IBA”) for purposes of the IBA setting the London interbank offered rate. As a result, it is possible that commencing in 2022, the London interbank offered rate may no longer be available or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on Loans. In light of this eventuality, public and private sector industry initiatives are currently underway to identify new or alternative reference rates to be used in place of the London interbank offered rate. In the event that the London interbank offered rate is no longer available or in certain other circumstances as set forth in Section 3.2(b) of this Agreement, such Section 3.2(b) provides a mechanism for determining an alternative rate of interest. The Administrative Agent will notify the Borrower, pursuant to Section 3.2, in advance of any change to the reference rate upon which the interest rate on Loans is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “LIBO Rate” or with respect to any alternative or successor rate thereto, or replacement rate thereof, including without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate, as it may or may not be adjusted pursuant to Section 3.2, will be similar to, or produce the same value or economic equivalence of, the LIBO Rate or have the same volume or liquidity as did the London interbank offered rate prior to its discontinuance or unavailability.

Section 1.6Amendment and Restatement. The Borrower and the Lenders acknowledge and agree that effective at the time at which all conditions precedent set forth in Section 5.1 have been satisfied, this Agreement shall amend and restate in its entirety the Existing Term Loan Agreement. It is the intention of the parties hereto that this Agreement shall not effectuate a novation of the indebtedness, obligations and liabilities of the Borrower under the Existing Term Loan Agreement, but merely constitute a restatement and, where applicable, a substitution of the terms governing such indebtedness, obligations and liabilities. All Loans made and Obligations incurred under the Existing Term Loan Agreement which are outstanding on the Effective Date shall continue as Loans and Obligations under (and shall be governed by the terms of) this Agreement and the other Loan Documents. Without limiting the foregoing, upon the effectiveness hereof: (a) all references in the “Loan Documents” (as defined in the Existing Term Loan Agreement) to the “Administrative Agent”, the “Credit Agreement” and the “Loan Documents” shall be deemed to refer to the Administrative Agent, this Agreement and the Loan Documents, and (b) all obligations constituting “Obligations” with any Lender or any Affiliate of any Lender which are outstanding on the Effective Date shall continue as Obligations under this Agreement and the other Loan Documents.

Subject to the terms and conditions set forth herein and effective as of the Effective Date, for all purposes of the Loan Documents, the Incremental Loan made hereunder shall constitute an increase in the aggregate amount of the Existing Loans incurred. Without limiting the foregoing, the Incremental Loan made hereunder shall mature on the Maturity Date, shall participate in any mandatory or voluntary prepayments on a pro rata basis with the Existing Loans and shall bear interest at the rates specified herein as applicable to the Existing Loans.

Exhibit 4

The Commitments will automatically terminate concurrently with the making of the Incremental Loan on the Effective Date. For the avoidance of doubt, the failure of any Lender to make its portion of the Incremental Loan shall not relieve any other Lender of its obligations hereunder, provided that the Commitments of the Lenders are several, and no Lender shall be responsible for any other Lender’s failure to make its portion of the Incremental Loan. Amounts repaid or prepaid in respect of the Loans may not be reborrowed.

Section 2.2Funding of Incremental Loan.

a.Not later than 2:00 p.m. New York City time on the Effective Date, each Lender shall deliver the proceeds of its portion of the Incremental Loan by wire transfer of immediately available funds to the account of the Administrative Agent designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such proceeds available to the Borrower by promptly crediting or otherwise transferring the amounts so received, in like funds, to an account of the Borrower designated by the Borrower to the Administrative Agent.

b.Unless the Administrative Agent shall have received notice from a Lender prior to the Effective Date that such Lender will not make the proceeds of its portion of the Incremental Loan available to the Administrative Agent, the Administrative Agent may assume that such Lender has made such proceeds available on such date in accordance with Section 2.2(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its portion of the Incremental Loan available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, 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 or (ii) in the case of the Borrower, the interest rate that would be otherwise applicable to the Loans. Any payment by the Borrower, however, shall be without prejudice to its rights against the applicable Lender. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s portion of the Incremental Loan.

Section 2.3Repayment of Loans; Evidence of Debt.

a.The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of such Lender’s Loan on the Maturity Date.

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

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

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

Exhibit 4

e.Any Lender may request that its Loan be evidenced by a Note in the original principal amount of such Lender’s Loan. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Loan evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 10.4) be represented by a Note payable to the order of the payee named therein or any Eligible Assignee pursuant to Section 10.4, except to the extent that any such Lender or Eligible Assignee subsequently returns any such Note for cancellation and requests that such Loan once again be evidenced as described in paragraphs (b) and (c) above.

Section 2.4Voluntary Prepayments. (a) The Borrower shall have the right at any time and from time to time to prepay any Loans in whole or in part, subject to the requirements of this Section 2.4.

a.The Borrower shall notify the Administrative Agent by telephone (confirmed by facsimile) of any prepayment under this Section 2.4, (i) in the case of a prepayment of Loans bearing interest at the LIBO Rate, not later than 11:30 a.m., New York City time, three Business Days before the date of prepayment or (ii) in the case of prepayment of Loans bearing interest at the Alternate Base Rate, not later than 11:30 a.m., New York City time, on the date of the prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of the Loans to be prepaid, provided that, such notice of prepayment may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Promptly following receipt of any such notice relating to the prepayment of Loans, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of Loans shall be in an integral multiple of $1,000,000 and not less than $5,000,000 (or, if the outstanding principal balance of the Loans is less than such minimum amount, then such lesser outstanding principal balance). Each prepayment of Loans shall be applied ratably to all of the then outstanding Loans. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.1 and, if applicable, shall be subject to the provisions of Section 3.4.

Section 2.5Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

a.The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal of Loans, interest or fees, or of amounts payable under Sections 3.3, 3.4, 3.5 or 10.3, or otherwise) prior to 2:00 p.m., 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 office at 10 S. Dearborn, Chicago, Illinois, or such other office as to which the Administrative Agent may notify the other parties hereto, except that payments pursuant to Sections 3.3, 3.4, 3.5 and 10.3 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.

b.Each payment or prepayment of principal or interest on the Loans shall be allocated pro rata among the Lenders in accordance with their Applicable Percentages. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal of Loans, interest, fees and commissions then due hereunder, such funds shall be applied (i) first, towards payment of interest, fees and commissions then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees and commissions then due to such parties and (ii) second, towards payment of principal of Loans then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal of the Loans then due to such parties.

Exhibit 4

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 of other Lenders 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 any of its Loans 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 applicable 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 such Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each such Lender 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 2.5(d), 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 Section until all such unsatisfied obligations are fully paid.

Section 2.6Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then, for so long as such Lender is a Defaulting Lender, the Commitments and Loans of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have voted or taken or may take any action hereunder (including any consent to any amendment, modification or waiver pursuant to Section 10.2); provided that (i) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender and (ii) any amendment or modification that increases, or extends the maturity of, such Defaulting Lender’s Commitment or reduces the principal amount of, or rate of interest on, any Loan made by such Defaulting Lender, shall require the consent of such Defaulting Lender.

ARTICLE 3.

INTEREST, FEES, YIELD PROTECTION, ETC.

Section 3.1Interest.

(a)The Borrower promises to pay interest on the unpaid principal amount of each Loan for the period commencing on the date such Loan is made until such Loan is paid in full at a rate per annum equal to the sum of the LIBO Rate for each applicable Interest Period plus 1.025%.

Exhibit 4

(b)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 in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraph of this Section or, in the case of any other amount, 2% plus the Alternate Base Rate from time to time in effect.

(c)Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date, provided that (i) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand and (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment.

(d)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, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent clearly demonstrable error. If any amount payable hereunder is bearing interest at the Alternate Base Rate, the Administrative Agent shall, as soon as practicable, notify the Borrower and the Lenders of the effective date and the amount of each change in the Prime Rate or Alternate Base Rate, but any failure to so notify shall not in any manner affect the obligation of the Borrower to pay interest hereunder in the amounts and on the dates required.

Section 3.2Alternate Rate of Interest.

a.If prior to the commencement of any Interest Period:

i.the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, (including because the LIBOR Screen Rate is not available or published on a current basis),for such Interest Period; or

ii.the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, telecopy or electronic mail 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, all Loans shall bear interest at the Alternate Base Rate.

b.If at any time the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth in clause (a)(i) have arisen and such circumstances are unlikely to be temporary or (ii) the circumstances set forth in clause (a)(i) have not arisen but either (w) the supervisor for the administrator of the LIBOR Screen Rate has made a public statement that the administrator of the LIBOR Screen Rate is insolvent (and there is no successor administrator that will continue publication of the LIBOR Screen Rate), (x) the administrator of the LIBOR Screen Rate has made a public statement identifying a specific date after which the LIBOR Screen Rate will permanently or indefinitely cease to be published by it (and there is no successor administrator that will continue publication of the LIBOR Screen Rate), (y) the supervisor for the administrator of the LIBOR Screen Rate has made a public statement identifying a specific date after which the LIBOR Screen Rate will permanently or indefinitely cease to be published or (z) the supervisor for the administrator of the LIBOR Screen Rate or a Governmental Authority

Exhibit 4

having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the LIBOR Screen Rate may no longer be used for determining interest rates for loans, then the Administrative Agent and the Borrower shall endeavor to establish an alternate rate of interest to the LIBO Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable (but for the avoidance of doubt, such related changes shall not include a reduction of the margin for the Loans set forth in Section 3.1(a)); provided that, if such alternate rate of interest as so determined would be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement. Notwithstanding anything to the contrary in Section 10.2, such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five Business Days of the date notice of such alternate rate of interest is provided to the Lenders, a written notice from the Required Lenders stating that such Required Lenders object to such amendment and describing in detail the basis for such objection. Until an alternate rate of interest shall be determined in accordance with this paragraph (b) (but, in the case of the circumstances described in clause (ii)(w), clause (ii)(x) or clause (ii)(y) of the first sentence of this Section 3.2(b), only to the extent the LIBOR Screen Rate for such Interest Period is not available or published at such time on a current basis), all Loans shall bear interest at the Alternate Base Rate.

Section 3.3Increased Costs; Illegality.

a.If any Change in Law shall:

i.impose, modify or deem applicable any reserve, special deposit, liquidity or similar requirement (including any compulsory loan requirement, insurance charge or other assessment) against assets of, deposits with or for the account of, or credit extended by, any Credit Party (except any such reserve requirement reflected in the Adjusted LIBO Rate);

ii.subject any Recipient to any Taxes with respect to this Agreement or on its Loans, loan principal, Commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto in respect thereof (other than (A) Indemnified Taxes and (B) Excluded Taxes); or

iii.impose on any Credit Party or the London interbank market any other condition affecting this Agreement or such Lender’s Loan;

and the result of any of the foregoing shall be to increase the cost to such Credit Party of making, continuing or maintaining its Loan or to reduce the amount of any sum received or receivable by such Credit Party hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Credit Party such additional amount or amounts as will compensate such Credit Party for such additional costs incurred or reduction suffered.

b.If any Credit Party determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Credit Party’s capital or on the capital of such Credit Party’s holding company, if any, as a consequence of this Agreement or its Loans to a level below that which such Credit Party or such Credit Party’s holding company could have achieved but for such Change in Law (taking into consideration such Credit Party’s policies and the policies of such Credit Party’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Credit Party such additional amount or amounts as will compensate such Credit Party or such Credit Party’s holding company for any such reduction suffered.

Exhibit 4

c.A certificate of a Credit Party setting forth the amount or amounts necessary to compensate such Credit Party or its holding company, as applicable, as specified in paragraph (a) or (b) ofthis Section shall be delivered to the Borrower and shall be conclusive and binding upon all parties hereto absent manifest error. The Borrower shall pay such Credit Party the amount shown as due on any such certificate within 10 Business Days after receipt thereof.

d.Failure or delay on the part of any Credit Party to demand compensation pursuant to this Section shall not constitute a waiver of such Credit Party’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Credit Party pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Credit Party notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Credit Party’s intention to claim compensation therefor; and providedfurther that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof but not to exceed a period of 365 days.

e.Notwithstanding any other provision of this Agreement, if, any Change in Law shall make it unlawful for any Lender to make or maintain its Loan at the Adjusted LIBO Rate, then, by written notice to the Borrower and to the Administrative Agent, such Lender may declare that, beginning on the date such unlawfulness becomes effective, such Lender’s Loan shall be bear interest at the Alternate Base Rate, unless such declaration shall be subsequently withdrawn.

Section 3.4Break Funding Payments. In the event of (a) the prepayment (voluntary or otherwise) of any principal of any Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the failure to borrow or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.4(b) and is revoked) or to continue a Loan for a new Interest Period in accordance herewith (other than at maturity) or (c) the assignment of any portion of a Loan other than on the last day of the relevant Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 3.6, then, in any such event, the Borrower shall compensate each applicable Lender for the loss, cost and expense attributable to such event. 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 that would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted 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 or continue a Loan, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate that 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 Business Days after receipt thereof.

Section 3.5Withholding of Taxes; Gross-Up.

a.Payments to be Free and Clear. Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

Exhibit 4

b.Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for, Other Taxes.

c.Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section, 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.

d.Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 10 Business Days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified 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 (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

e.Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.4(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such 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 any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to setoff and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

f.Status of Lenders.

i.Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.5(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

ii.Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,

Exhibit 4

A.any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), an executed copy of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

B.any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

1. in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, an executed copy of IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

2. in the case of a Foreign Lender claiming that its extension of credit will generate U.S. effectively connected income, an executed copy of IRS Form W-8ECI;

3. in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit D-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) an executed copy of IRS Form W-8BEN-E or IRS Form W-8BEN; or

4. to the extent a Foreign Lender is not the beneficial owner, an executed copy of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit D-2 or Exhibit D-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit D-4 on behalf of each such direct and indirect partner;

C.any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law

Exhibit 4

as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

D.if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

g.Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (g) the payment of which would place the indemnified party in a less favorable net after-tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the indemnifying party or any other Person.

h.Survival. Each party’s obligations under this Section shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

In the event that the Borrower becomes obligated to pay additional amounts to any Lender (or to any Governmental Authority for the account of any Lender) pursuant to Section 3.3, Section 3.4 or Section 3.5, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans 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 3.3, Section 3.4 or Section 3.5, 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

Exhibit 4

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.Replacement of Lenders. In the event that (i) the Borrower becomes obligated to pay additional amounts to any Lender (or to any Governmental Authority for the account of any Lender) pursuant to Section 3.3, Section 3.4 or Section 3.5, (ii) any Lender becomes a Defaulting Lender or (iii) any Lender has failed to consent to a proposed amendment, waiver, discharge or termination that under Section 10.2 requires the consent of all the Lenders and with respect to which the Required Lenders shall have granted their consent, then the Borrower may, at its sole cost and expense, within 60 days of the demand by such Lender for such additional amounts or the relevant default or action or inaction by such Lender, as the case may be, and subject to and in accordance with the provisions of Section 10.4 (with the Borrower obligated to pay any applicable processing and recordation fee), designate an Eligible Assignee (acceptable to the Administrative Agent) to purchase and assume all of such Lender’s interests, rights and obligations under the Loan Documents, without recourse to or warranty by or expense to, such Lender, for a purchase price equal to the outstanding principal amount of such Lender’s Loans plus any accrued but unpaid interest thereon and any other amounts payable to such Lender hereunder, and to assume all the obligations of such Lender hereunder, and, upon such purchase, such Lender shall no longer be a party hereto or have any rights hereunder (except those that survive full repayment hereunder) and shall be relieved from all obligations to the Borrower hereunder, and the Eligible Assignee shall succeed to the rights and obligations of such Lender hereunder. No replacement of a Defaulting Lender pursuant to this Section 3.6 shall be deemed to be a waiver of any right that the Borrower, the Administrative Agent or any other Lender may have against such Defaulting Lender. The Borrower shall execute and deliver to such Eligible Assignee a Note. Notwithstanding anything herein to the contrary, in the event that a Lender is replaced pursuant to this Section 3.6 as a result of the Borrower becoming obligated to pay additional amounts to such Lender (or to any Governmental Authority for the account of any Lender)pursuant to Section 3.3, Section 3.4 or Section 3.5, such Lender shall be entitled to receive such additional amounts as if it had not been so replaced.

It is understood that this covenant relates only to working order and condition of such property in accordance with prudent industry practices and shall not be construed as a covenant not to dispose of property.

Exhibit 4

Section 6.7Observance of Legal Requirements. The Borrower shall observe and comply in all material respects, and cause each of its Subsidiaries so to do, with all laws, regulations and orders of any Governmental Authority which now or at any time hereafter may be applicable to it, including ERISA and all Environmental Laws, a violation of which would individually or collectively reasonably be expected to have a Material Adverse Effect, except such thereof as shall be contested in good faith and, if applicable, by appropriate proceedings diligently conducted by it.

ARTICLE 9.

THE ADMINISTRATIVE AGENT

Section 9.1Authorization and Action.

a.Each Credit Party 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.

b.The Person 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 Person 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.

c.As to any matters not expressly provided for herein and in the other Loan Documents (including enforcement or collection), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written instructions of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, pursuant to the terms in the Loan Documents), and, unless and until revoked in writing, such instructions shall be binding upon each Lender; provided, however, that the Administrative Agent shall not be required to take any action that (i) the Administrative Agent in good faith believes exposes it to liability unless the Administrative Agent receives an indemnification and is exculpated in a manner satisfactory to it from the Lenders with respect to such action or (ii) is contrary to this Agreement or any other Loan Document or applicable law, including any action that may be in violation of the automatic stay under any requirement of law relating to bankruptcy, insolvency or reorganization or relief of debtors or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any requirement of law relating to bankruptcy, insolvency or reorganization or relief of debtors; provided, further, that the Administrative Agent may seek clarification or direction from the Required Lenders prior to the exercise of any such instructed action and may refrain from acting until such clarification or direction has been provided. Except as expressly set forth in the Loan Documents, 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, any Subsidiary or any Affiliate of any of the foregoing that is communicated to or obtained by the Person serving as Administrative Agent or any of its Affiliates in any capacity. Nothing in this Agreement shall require the Administrative Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

d.In performing its functions and duties hereunder and under the other Loan Documents, the Administrative Agent is acting solely on behalf of the Lenders (except in limited circumstances expressly provided for herein relating to the maintenance of the Register), and its duties are entirely mechanical and administrative in nature. Without limiting the generality of the foregoing:

i.the Administrative Agent does not assume and shall not be deemed to have assumed any obligation or duty or any other relationship as the agent, fiduciary or trustee of or for any Lender other than as expressly set forth herein and in the other Loan Documents, regardless of whether a Default or an Event of Default has occurred and is continuing (and it is understood and agreed that the use of the term “agent” (or any similar term) herein or in any other Loan Document with reference

Exhibit 4

to the Administrative Agent is not intended to connote any fiduciary duty or other implied (or express) obligations arising under agency doctrine of any applicable law, and that such term is used as a matter of market custom and is intended to create or reflect only an administrative relationship between contracting parties); additionally, each Lender agrees that it will not assert any claim against the Administrative Agent based on an alleged breach of fiduciary duty by the Administrative Agent in connection with this Agreement and/or the transactions contemplated hereby; and

ii.nothing in this Agreement or any Loan Document shall require the Administrative Agent to account to any Lender for any sum or the profit element of any sum received by the Administrative Agent for its own account;

e.The Administrative Agent may perform any of its duties and exercise its rights and powers hereunder or under any other Loan Document 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 of their respective duties and exercise their respective rights and powers through their respective Related Parties. The exculpatory provisions of this Article 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 pursuant to this Agreement. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agent.

f.The Sole Lead Arranger and Sole Bookrunner shall have no obligations or duties whatsoever in such capacity under this Agreement or any other Loan Document and shall incur no liability hereunder or thereunder in such capacity, but shall have the benefit of the indemnities provided for hereunder.

g.In case of the pendency of any proceeding with respect to the Borrower under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise:

i.to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other obligations under the Loan Documents that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim under Sections 3.1, 3.3, 3.5 and 10.3) allowed in such judicial proceeding; and

ii.to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due to it, in its capacity as the Administrative Agent, under the Loan Documents (including under Section 10.3). Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

h.The provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders, and, except solely to the extent of the Borrower’s rights to consent pursuant to and subject to the conditions set forth in this Article, none of the Borrower or any Subsidiary, or any of their respective Affiliates, shall have any rights as a third party beneficiary under any such provisions.

Exhibit 4

Section 9.2Administrative Agent’s Reliance, Indemnification, Etc.

a.Neither the Administrative Agent nor any of its Related Parties shall be (i) liable for any action taken or omitted to be taken by such party under or in connection with this Agreement or the other Loan Documents (x) with the consent of or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith to be necessary, under the circumstances as provided in the Loan Documents) or (y) in the absence of its own gross negligence or willful misconduct (such absence to be presumed unless otherwise determined by a court of competent jurisdiction by a final and non-appealable judgment) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made the Borrower or any officer thereof contained in this Agreement or any other Loan 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 connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder.

b.The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof (stating that it is a “notice of default”) 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 any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document or the occurrence of any Default, (iv) the sufficiency, validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article 5 or elsewhere in any Loan Document, other than to confirm receipt of items (which on their face purport to be such items) expressly required to be delivered to the Administrative Agent or satisfaction of any condition that expressly refers to the matters described therein being acceptable or satisfactory to the Administrative Agent.

c.Without limiting the foregoing, the Administrative Agent (i) may treat the payee of any Note as its holder until such Note has been assigned in accordance with Section 10.4, (ii) may rely on the Register to the extent set forth in Section 10.4(c), (iii) may consult with legal counsel (including counsel to the Borrower), independent public accountants and other experts selected by it, and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts, (iv) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made by or on behalf of the Borrower in connection with this Agreement or any other Loan Document, (v) in determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender Bank sufficiently in advance of the making of such Loan and (vi) shall be entitled to rely on, and shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon, any notice, consent, certificate or other instrument or writing (which writing may be a fax, any electronic message, Internet or intranet website posting or other distribution) or any statement made to it orally or by telephone and believed by it to be genuine and signed or sent or otherwise authenticated by the proper party or parties (whether or not such Person in fact meets the requirements set forth in the Loan Documents for being the maker thereof).

Section 9.3Posting of Communications.

a.The Borrower agrees that the Administrative Agent may, but shall not be obligated to, make any Communications available to the Lenders by posting the Communications on IntraLinks™, DebtDomain, SyndTrak, ClearPar or any other electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”).

b.Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date, a user ID/password authorization system) and the Approved Electronic

Exhibit 4

Platform is secured through a per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders and the Borrower acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure, that the Administrative Agent is not responsible for approving or vetting the representatives or contacts of any Lender that are added to the Approved Electronic Platform, and that there may be confidentiality and other risks associated with such distribution. Each of the Lenders and the Borrower hereby approves distribution of the Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution.

c.THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. THE APPLICABLE PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE APPROVED ELECTRONIC PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE APPLICABLE PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT, THE SOLE LEAD ARRANGER AND SOLE BOOKRUNNER OR ANY OF THEIR RESPECTIVE RELATED PARTIES (COLLECTIVELY, “APPLICABLE PARTIES”) HAVE ANY LIABILITY TO THE BORROWER, ANY LENDER OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF THE BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET OR THE APPROVED ELECTRONIC PLATFORM.

“Communications” means, collectively, any notice, demand, communication, information, document or other material provided by or on behalf of the Borrower pursuant to any Loan Document or the transactions contemplated therein which is distributed by the Administrative Agent or any Lender by means of electronic communications pursuant to this Section, including through an Approved Electronic Platform.

d.Each Lender agrees that notice to it (as provided in the next sentence) specifying that Communications have been posted to the Approved Electronic Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (i) to notify the Administrative Agent in writing (which could be in the form of electronic communication) from time to time of such Lender’s email address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such email address.

e.Each of the Lenders and the Borrower agrees that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally applicable document retention procedures and policies.

f.Nothing herein shall prejudice the right of the Administrative Agent or any Lender to give any notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document.

Section 9.4The Administrative Agent Individually. With respect to its Commitment and Loans, the Person serving as the Administrative Agent shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender. The terms “Lenders”, “Required Lenders” and any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity as a Lender or as one of the Required Lenders, as applicable. The Person serving as the Administrative Agent and its Affiliates may accept deposits from, lend money to, own securities of, act

Exhibit 4

as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust or other business with, the Borrower, any Subsidiary or any Affiliate of any of the foregoing as if such Person was not acting as the Administrative Agent and without any duty to account therefor to the Lenders.

Section 9.5Successor Administrative Agent.

a.The Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof to the Lenders and the Borrower, whether or not a successor Administrative Agent has been appointed. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of 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. In either case, such appointment shall be subject to the prior written approval of the Borrower (which approval may not be unreasonably withheld and shall not be required while an Event of Default has occurred and is continuing). Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent, such successor Administrative Agent shall succeed to, and become vested with, all the rights, powers, privileges and duties of the retiring Administrative Agent. Upon the acceptance of appointment as Administrative Agent by a successor Administrative Agent, the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. Prior to any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the retiring Administrative Agent shall take such action as may be reasonably necessary to assign to the successor Administrative Agent its rights as Administrative Agent under the Loan Documents.

b.Notwithstanding paragraph (a) of this Section, in the event no successor Administrative Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its intent to resign, the retiring Administrative Agent may give notice of the effectiveness of its resignation to the Lenders and the Borrower, whereupon, on the date of effectiveness of such resignation stated in such notice, (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents; and (ii) the Required Lenders shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent; provided that (A) all payments required to be made hereunder or under any other Loan Document to the Administrative Agent for the account of any Person other than the Administrative Agent shall be made directly to such Person and (B) all notices and other communications required or contemplated to be given or made to the Administrative Agent shall directly be given or made to each Lender. Following the effectiveness of the Administrative Agent’s resignation from its capacity as such, the provisions of this Article and Section 10.3, as well as any exculpatory, reimbursement and indemnification provisions set forth in any other Loan Document, 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 the retiring Administrative Agent was acting as Administrative Agent.

Section 9.6Acknowledgements of Lenders.

a.Each Lender represents that it is engaged in making, acquiring or holding commercial loans in the ordinary course of its business and that it has, independently and without reliance upon the Administrative Agent, the Sole Lead Arranger and Sole Bookrunner or any other Lender, or any of the Related Parties of any of the foregoing, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement as a Lender, and to make, acquire or hold Loans hereunder. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the Sole Lead Arranger and Sole Bookrunner or any other Lender, or any of the Related Parties of any of the foregoing, and based on such documents and information (which may contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) 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 other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Exhibit 4

b.Each Lender, by delivering its signature page to this Agreement on the Effective Date, or delivering its signature page to an Assignment and Assumption or any other Loan Document pursuant to which it shall become a Lender hereunder, shall be deemed to have acknowledged receipt of, and consented to and approved, each Loan Document and each other document required to be delivered to, or be approved by or satisfactory to, the Administrative Agent or the Lenders on the Effective Date.

Section 9.7Certain ERISA Matters.

a.Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and the Sole Lead Arranger and Sole Bookrunner and their respective Affiliates, and not, for the avoidance of doubt, to or for the benefit of the Borrower, that at least one of the following is and will be true:

Section 10.2Waivers; Amendments.

a.No failure or delay by any Credit Party in exercising any right or power under any Loan Document 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 Credit Parties under the Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document 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 any Credit Party may have had notice or knowledge of such Default at the time.

b.Neither any Loan Document nor any provision thereof 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 any interest, or reduce any fees, payable under the Loan Documents, without the written consent of each Credit Party affected thereby, (iii) postpone the date of payment at stated maturity of any Loan, or the date of any interest or any fees payable under the Loan Documents, or reduce the amount of, waive or excuse any such payment, without the written consent of each Credit Party affected thereby, (iv) change any provision hereof in a manner that would alter the pro rata sharing of payments required by Section 2.5(b) or 2.5(c) without the written consent of each Credit Party affected thereby, and (v) change any of the provisions of this Section or the definition of the term “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, or change the currency in which Loans are to be made or payment under the Loan Documents is to be made, or add additional borrowers, without the written consent of each Lender, and providedfurther 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, as applicable. Notwithstanding the foregoing, no consent with respect to any amendment, waiver or other modification of this Agreement shall be required of any Defaulting Lender, except with respect to any amendment, waiver or other modification referred to in clause (i), (ii) or (iii) of the first proviso of this paragraph and then only in the event such Defaulting Lender shall be directly affected by such amendment, waiver or other modification.

c.Notwithstanding anything to the contrary herein the Administrative Agent may, with the consent of the Borrower only, amend, modify or supplement this Agreement or any of the other Loan Documents to cure any ambiguity, omission, mistake, defect or inconsistency.

Exhibit 4

Section 10.3Expenses; Indemnity; Damage Waiver.

a.Cost and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket costs and 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 and distribution (including, without limitation, via the internet or through a service such as Intralinks) of the term loan facility provided for herein, the preparation and administration of each Loan Document or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated thereby shall be consummated) and (ii) all reasonable out-of-pocket costs and expenses incurred by any Credit Party, including the reasonable fees, charges and disbursements of any counsel for any Credit Party and any consultant or expert witness fees and expenses, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including all such reasonable out-of-pocket costs and expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

b.Indemnification by the Borrower. The Borrower shall indemnify each Credit Party and each Related Party thereof (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 reasonable 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 any Loan Document or any agreement or instrument contemplated thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated thereby, (ii) any Loan or the use of the proceeds thereof, (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 the Subsidiaries, or any liability under any Environmental Law related in any way to the Borrower or any of the Subsidiaries or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not such claim, litigation, investigation or proceeding is brought by the Borrower or any or its equity holders, Affiliates, creditors or any other third Person and 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 (x) the gross negligence or willful misconduct of such Indemnitee or (y) a breach in bad faith by such Indemnitee or arising solely from claims between or among one or more Indemnitees.

c.Reimbursement by Lenders. 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 (and without limiting the Borrower’s obligation to do so), each Lender severally agrees to pay to the Administrative Agent an amount equal to the product of such unpaid amount multiplied by a fraction, the numerator of which is the outstanding principal balance of such Lender’s Loans and the denominator of which is the outstanding principal balance of all Lender’s Loans (in each case determined as of the time that the applicable unreimbursed expense or indemnity payment is sought), provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as applicable, was incurred by or asserted against the Administrative Agent in its capacity as such.

d.Waiver of Consequential Damages, etc. To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, (i) subject to the provisions of Section 10.15, for any damages arising from the use by others of information or other materials obtained through telecommunications, electronic or other information transmission systems (including the Internet) (except for any claims by the Borrower for damages arising from the gross negligence or willful misconduct of such Indemnitee, which claims shall be permitted by this Section 10.3(d)(i); provided that no Indemnitee shall be liable for any such damages except to the extent determined by a court of competent jurisdiction in a final nonappealable judgment) or (ii) on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct and actual damages) arising out of, in connection with, or as a result of, any Loan Document or any agreement, instrument or other document contemplated thereby, the Transactions or any Loan or the use of the proceeds thereof.

Exhibit 4

e.Payments. All amounts due under this Section shall be payable promptly but in no event later than ten days after written demand therefor.

Section 10.4Successors and Assigns.

a.Successors and Assigns Generally. 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 the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). 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 (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each Credit Party) any legal or equitable right, remedy or claim under or by reason of this Agreement.

b.Assignments by Lenders. Any Lender may (and if demanded by Borrower pursuant to Section 3.6 shall to the extent required thereby) at any time assign to one or more Eligible 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); provided that any such assignment shall be subject to the following conditions:

i.Minimum Amounts.

1.In the case of an assignment of the entire remaining amount of the assigning Lender’s Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

2.In any case not described in paragraph (b)(i)(A) of this Section, the principal outstanding balance of the Loans 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000.

ii.Proportionate Amounts. 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 with respect to the Loan or the Commitment assigned.

iii.Required Consents. For each such assignment, the consent of:

1.the Borrower (such consent not to be unreasonably withheld) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five Business Days after having received notice thereof; and

2.the Administrative Agent (such consent not to be unreasonably withheld); provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Loan to a Lender, an Affiliate of a Lender or an Approved Fund.

Exhibit 4

iv.Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent (x) an Assignment and Assumption or (y) to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to an Approved Electronic Platform as to which the Administrative Agent and the parties to the Assignment and Assumption are participants, together with a processing and recordation fee of $3,500 (such fee to be paid by either the assigning Lender or the assignee Lender or shared between such Lenders), and the Eligible Assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about the Borrower and its Affiliates and their Related Parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws.

v.No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

vi.No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement 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 3.3, 3.4, 3.5 and 10.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph 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 (d) of this Section.

c.Register.

i.The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in New York, New York a copy of each Assignment and Assumption (or, to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to an Approved Electronic Platform as to which the Administrative Agent and the parties to the Assignment and Assumption are participants) delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans 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.

ii.Upon its receipt of (x) a duly completed Assignment and Assumption executed by an assigning Lender and an assignee or (y) to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to an Approved Electronic Platform as to which the Administrative Agent and the parties to the Assignment and Assumption are participants, 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

Exhibit 4

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 10.3(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.

d.Participations. Any Lender may at any time, without the consent of, but with notice to, the Borrower and the Administrative Agent (provided that any failure to give such notice shall not impair the effectiveness of such participation except as expressly provided in paragraph (e) of this Section), sell participations to any Eligible Assignee (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any Note for all purposes of this Agreement and (iv) the Borrower, the Administrative Agent and each Credit Party shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Notwithstanding the foregoing, in no event may a participation be granted to any entity which is not a commercial bank, finance company, insurance company or other financial institution or fund (whether a corporation, partnership or other entity) engaged generally in making, purchasing or otherwise investing in commercial loans in the ordinary course of its business without the express prior written consent of the Borrower.

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 waiver with respect to the following matters described in clauses (ii) and (iii)of the first proviso in Section 10.2(b) that directly affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.3, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section but (x) shall not be entitled to recover greater amounts under any such Section than the selling Lender would be entitled to recover and (y) shall be subject to replacement by the Borrower under Section 3.6 to the same extent as if it were a Lender; provided that such replacement Participant shall be an Eligible Assignee engaged generally in making, purchasing or otherwise investing in commercial loans in the ordinary course of its business. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.8as though it were a Lender, provided such Participant agrees to be subject to Section 2.5(c) as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

e.Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 3.3 or 3.5 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 3.5 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 3.5(f) as though it were a Lender.

Exhibit 4

f.Certain Pledges. 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 any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 10.5Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of any Loan Document and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any Credit Party 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 the Loan Documents is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 3.4, 3.5, 3.6, 10.3, 10.9, 10.10 and Article 9 shall survive and remain in full force and effect regardless of the consummation of the Transactions, the repayment of the Loans or the termination of this Agreement or any provision hereof.

Section 10.6Counterparts; Integration; Effectiveness; Electronic Execution. 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, the other Loan Documents 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 5.1, 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 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 telecopy, e-mailed .pdf or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to any document to be signed in connection with this Agreement and the transactions contemplated hereby shall be deemed to include Electronic Signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided that nothing herein shall require the Administrative Agent to accept electronic signatures in any form or format without its prior written consent.

Section 10.7Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties 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.

Section 10.8Right of Set-off. If an Event of Default shall have occurred and be continuing, and the acceleration of all obligations owing in connection with the Loan Documents, or at any time upon the occurrence and during the continuance of an Event of Default under paragraph (a) of Article 8, each of the Lenders and their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable 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 it to or for the credit or the account of the Borrower against any of the Obligations

Exhibit 4

now or hereafter existing under this Agreement and the other Loan Documents held by it, irrespective of whether or not it shall have made any demand therefor and although such Obligations may be unmatured. The rights of each of the Lenders and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of set-off) that it may have. Each Lender agrees promptly to notify the Borrower 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.

b.Each of the parties hereto 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 the Borough of Manhattan and of the United States District Court of the Southern District of New York City, sitting in the Borough of Manhattan, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that, to the extent permitted by applicable law, all claims in respect of any such action or proceeding may be heard and determined in such New York State court or, to the extent permitted by applicable law, in such Federal court.

Section 10.16No Fiduciary Duty. The Administrative Agent, each Lender and their Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the Borrower, their stockholders and/or their affiliates. The Borrower agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Lender, on the one hand, and such Borrower, its stockholders or its affiliates, on the other. The Borrower acknowledges and agrees that (i) the transactions contemplated by the Loan Documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Lender has assumed an advisory or fiduciary responsibility in favor of the Borrower, its stockholders or its affiliates with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender has advised, is currently advising or will advise the Borrower, its stockholders or its Affiliates on other matters) or any other obligation to the Borrower except the obligations expressly set forth in the Loan Documents and (y) each Lender is acting solely as principal and not as the agent or fiduciary of the Borrower, its management, stockholders, creditors or any other Person. The Borrower acknowledges and agrees that it has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Borrower, in connection with such transaction or the process leading thereto.

The Borrower further acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that each Credit Party is a full service securities or banking firm engaged in securities trading and brokerage activities as well as providing investment banking and other financial services. In the ordinary course of business, any Credit Party may provide investment banking and other financial services to, and/or acquire, hold or sell, for its own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of, the Borrower and other companies with which it may have commercial or other relationships. With respect to any securities and/or financial instruments so held by any Credit Party or any of its customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the holder of the rights, in its sole discretion.

Exhibit 4

In addition, the Borrower acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that each Credit Party and its affiliates may be providing debt financing, equity capital or other services (including financial advisory services) to other companies in respect of which the Borrower or its Subsidiaries may have conflicting interests regarding the transactions described herein and otherwise. No Credit Party will use confidential information obtained from the Borrower by virtue of the transactions contemplated by the Loan Documents or its other relationships with the Borrower in connection with the performance by such Credit Party of services for other companies, and no Credit Party will furnish any such information to other companies. The Borrower also acknowledges that no Credit Party has any obligation to use in connection with the transactions contemplated by the Loan Documents, or to furnish to the Borrower, confidential information obtained from other companies.

Section 10.17Acknowledgment and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Loan Document may be subject to the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

a.the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

b.the effects of any Bail-In Action on any such liability, including, if applicable:

i.a reduction in full or in part or cancellation of any such liability;

ii.a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

iii.the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

Section 10.18Acknowledgement Regarding Any Supported QFC. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Swap Agreements or any other agreement or instrument that is a QFC (such support “QFC Credit Support” and each such QFC a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):

Exhibit 4

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

The Loan evidenced by this Note is prepayable in the amounts, and under the circumstances, and its maturity is subject to acceleration upon the terms, set forth in the Term Loan Agreement. This Note is subject to, and shall be construed in accordance with, the provisions of the Term Loan Agreement.

The Borrower shall not have the right to assign its rights or obligations hereunder or any interest herein (and any such attempted assignment shall be void), except as expressly permitted by the Loan Documents. No failure or delay of the Lender in exercising any power or right 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. Neither this Note nor any provision hereof may be waived, amended or modified, nor shall any departure therefrom be consented to, except pursuant to a written agreement entered into between the Borrower and the Lender with respect to which such waiver, amendment, modification or consent is to apply, subject to any consent required in accordance with Section 10.2 of the Term Loan Agreement.

The Borrower, and by accepting this Note, the Lender, 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 Note shall affect any right that the Lender may otherwise have to bring

any action or proceeding relating to this Note or the other Loan Documents against the Borrower, or any of its property, in the courts of any jurisdiction.

The Borrower, and by accepting this Note, the Lender, hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Note or the other Loan Documents in any court referred to in the preceding paragraph hereof. The Borrower, and by accepting this Note, the Lender, hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

The Borrower, and by accepting this Note, the Lender, irrevocably consents to service of process in the manner provided for notices herein. Nothing herein will affect the right of the Lender to serve process in any other manner permitted by law.
