If no election is received with respect to the conversion to or the renewal of the LIBOR Rate Option for any Loans by 12:00 p.m. Eastern time three (3) Business Days prior to the end of the Interest Period with respect thereto, such Loan shall be converted to the Base Rate Option. Each Loan Request shall be irrevocable and shall specify the aggregate amount of the proposed Loans comprising each Borrowing Tranche, and, if applicable, the Interest Period, which amounts shall be in (x) integral multiples of $100,000 and not less than $1,000,000 for each Borrowing Tranche under the LIBOR Rate Option, and (y) integral multiples of $100,000 and not less than $1,000,000 for each Borrowing Tranche under the Base Rate Option. 2.5.2.

Each Swing Loan Request shall be irrevocable and shall specify the proposed Borrowing Date and the principal amount of such Swing Loan, which shall be not less than $250,000. 2.6 Making Revolving Credit Loans and Swing Loans; Presumptions by the Administrative Agent; Repayment of Revolving Credit Loans; Borrowings to Repay Swing Loans. 2.6.1. Making Revolving Credit Loans. The Administrative Agent shall, promptly after receipt by it of a Loan Request pursuant to Section 2.5 [Revolving Credit Loan {N0289348 2 } 39

Requests; Swing Loan Requests], notify the Lenders of its receipt of such Loan Request specifying the information provided by the Administrative Borrower and the apportionment among the Lenders of the requested Revolving Credit Loans as determined by the Administrative Agent in accordance with Section 2.2 [Nature of Lenders’ Obligations with Respect to Revolving Credit Loans]. Each Lender shall remit the principal amount of each Revolving Credit Loan to the Administrative Agent such that the Administrative Agent is able to, and the Administrative Agent shall, to the extent the Lenders have made funds available to it for such purpose and subject to Section 7.2 [Each Loan or Letter of Credit], fund such Revolving Credit Loans to the Borrowers in U.S. Dollars and immediately available funds at the Principal Office prior to 2:00 p.m. Eastern time on the applicable Borrowing Date; provided that if any Lender fails to remit such funds to the Administrative Agent in a timely manner, the Administrative Agent may elect in its sole discretion to fund with its own funds the Revolving Credit Loans of such Lender on such Borrowing Date, and such Lender shall be subject to the repayment obligation in Section 2.6.2 [Presumptions by the Administrative Agent]. 2.6.2. Presumptions by the Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Loan that such Lender will not make available to the Administrative Agent such Lender’s share of such Loan, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.6.1 [Making Revolving Credit Loans] 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 share of the applicable Loan available to the Administrative Agent, then the applicable Lender and the Borrowers 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 Borrowers to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by 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 and (ii) in the case of a payment to be made by the Borrowers, the interest rate applicable to Loans under the Base Rate Option. If such Lender pays its share of the applicable Loan to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan. Any payment by the Borrowers shall be without prejudice to any claim the Borrowers may have against a Lender that shall have failed to make such payment to the Administrative Agent. 2.6.3. Making Swing Loans. So long as FNB elects to make Swing Loans, FNB shall, after receipt by it of a Swing Loan Request pursuant to Section 2.5.2 [Swing Loan Requests], fund such Swing Loan to the Borrowers in U.S. Dollars and immediately available funds at the Principal Office prior to 2:00 p.m. Eastern time on the Borrowing Date. 2.6.4. Repayment of Revolving Credit Loans. The Borrowers shall repay the Revolving Credit Loans together with all outstanding interest thereon on the Expiration Date. 2.6.5. Borrowings to Repay Swing Loans. FNB may, at its option, exercisable at any time for any reason whatsoever, demand repayment of the Swing Loans, and each Lender shall make a Revolving Credit Loan in an amount equal to such Lender’s Ratable Share of the aggregate principal amount of the outstanding Swing Loans, plus, if FNB so requests, accrued interest thereon, provided that no Lender shall be obligated in any event to make Revolving Credit Loans in excess of its Revolving Credit Commitment minus its Ratable Share of Letter of {N0289348 2 } 40

Credit Obligations. Revolving Credit Loans made pursuant to the preceding sentence shall bear interest at the Base Rate Option and shall be deemed to have been properly requested in accordance with Section 2.5.1 [Revolving Credit Loan Requests] without regard to any of the requirements of that provision. FNB shall provide notice to the Lenders (which may be telephonic or written notice by letter, facsimile or telex) that such Revolving Credit Loans are to be made under this Section 2.6.5 and of the apportionment among the Lenders, and the Lenders shall be unconditionally obligated to fund such Revolving Credit Loans (whether or not the conditions specified in Section 2.5.1 [Revolving Credit Loan Requests] are then satisfied) by the time FNB so requests, which shall not be earlier than 3:00 p.m. Eastern time on the Business Day next after the date the Lenders receive such notice from FNB. 2.6.6. [RESERVED]. 2.7 Amended and Restated Notes. The Obligation of the Borrowers to repay the aggregate unpaid principal amount of the Revolving Credit Loans, Swing Loans and Term Loans made to it by each Lender, together with interest thereon, shall be evidenced by a revolving credit Amended and Restated Note, a swing Amended and Restated Note and a term Amended and Restated Note, dated the Closing Date payable to such Lender (or its registered assigns) in a face amount equal to the Revolving Credit Commitment, Swing Loan Commitment or Term Loan Commitment, as applicable, of such Lender. 2.8 Use of Proceeds. The proceeds of the Revolving Credit Loans, the Swing Loans and Term Loans shall be used solely: (i) to finance a portion of the Acquisition, including fees and expenses related to the Acquisition; (ii) to refinance existing indebtedness; (iii) to pay fees and expenses in connection with this Agreement and the other Loan Documents and the closing of the Loans; and (iv) for ongoing general corporate and general working capital purposes of the Borrowers. 2.9 Letter of Credit Subfacility. 2.9.1. Issuance of Letters of Credit. The Administrative Borrower, on behalf of the Borrowers, may request the issuance of a letter of credit (each a “Letter of Credit”) on behalf of itself or another Loan Party by delivering or having such other Loan Party deliver to the Administrative Agent a completed application and agreement for letters of credit in such form as the Administrative Agent may specify from time to time by no later than 10:00 a.m. Eastern time at least five (5) Business Days, or such shorter period as may be agreed to by the Administrative Agent, in advance of the proposed date of issuance. Each Letter of Credit shall be a Standby Letter of Credit (and may not be a Commercial Letter of Credit). Promptly after receipt of any Letter of Credit application, the Issuing Lender shall confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit application and if not, such Issuing Lender will provide the Administrative Agent with a copy thereof. Unless the Issuing Lender has received notice from any Lender, the Administrative Agent or any Loan Party, at least one day prior to the requested date of issuance, amendment or extension of the applicable Letter of Credit, that one or more applicable conditions in Section 7 [Conditions of Lending and Issuance of Letters of Credit] is not satisfied, then, subject to the terms and conditions hereof and in reliance on the agreements of the other Lenders set forth in this Section 2.9, the Issuing Lender or any of the Issuing Lender’s Affiliates will issue a Letter of Credit or agree to such amendment or extension, {N0289348 2 } 41

provided that each Letter of Credit shall (A) shall be denominated on Dollars, (B) have a maximum maturity of twelve (12) months from the date of issuance, and (C) in no event expire later than the Expiration Date and provided further that in no event shall (i) the Letter of Credit Obligations exceed, at any time, $5,000,000 (the “Letter of Credit Sublimit”), (ii) the Revolving Facility Usage exceed, at any one time, the Revolving Credit Commitments or (iii) the Revolving Facility Usage exceed, at any one time, the Maximum Borrowing Base. Each request by the Administrative Borrower, on behalf of the Borrowers, for the issuance, amendment, or extension of a Letter of Credit shall be deemed to be a representation by the Borrowers that they shall be in compliance with the preceding sentence and with Section 7 [Conditions of Lending and Issuance of Letters of Credit] after giving effect to the requested issuance, amendment, or extension of such Letter of Credit. Promptly after its delivery of any Letter of Credit or any amendment to any Letter of Credit to the beneficiary thereof, the applicable Issuing Lender will also deliver to the Administrative Borrower, on behalf of the Borrowers, and the Administrative Agent a true and complete copy of such Letter of Credit or amendment. 2.9.2. Letter of Credit Fees. The Borrowers shall pay (i) to the Administrative Agent for the ratable account of the Lenders a fee (the “Letter of Credit Fee”) equal to the Applicable Letter of Credit Fee Rate on the daily amount available to be drawn under each Letter of Credit, and (ii) to the Issuing Lender for its own account a fronting fee equal to the greater of (x) .25% per annum on the daily amount available to be drawn under each Letter of Credit, and (y) $500. All Letter of Credit Fees and fronting fees shall be computed on the basis of a year of 360 days and actual days elapsed and shall be payable quarterly in arrears on each Payment Date following issuance of each Letter of Credit. The Borrowers shall also pay to the Issuing Lender for the Issuing Lender’s sole account the Issuing Lender’s then in effect customary fees and administrative expenses payable with respect to the Letters of Credit as the Issuing Lender may generally charge or incur from time to time in connection with the issuance, maintenance, amendment (if any), assignment or transfer (if any), negotiation, and administration of Letters of Credit. 2.9.3. Disbursements, Reimbursement. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Lender a participation in such Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Ratable Share of the maximum amount available to be drawn under such Letter of Credit and the amount of such drawing, respectively. In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, the Issuing Lender will promptly notify the Borrowers and the Administrative Agent thereof. Provided that it shall have received such notice, the Borrowers shall reimburse (such obligation to reimburse the Issuing Lender shall sometimes be referred to as a “Reimbursement Obligation”) the Issuing Lender prior to 12:00 p.m. Eastern time on the first Business Day following the date that an amount is paid by the Issuing Lender under any Letter of Credit (each such date, a “Drawing Date”) by paying to the Administrative Agent for the account of the Issuing Lender an amount equal in Dollars to the amount so paid by the Issuing Lender. 2.9.3.1 In the event the Borrowers fail to reimburse the Issuing Lender (through the Administrative Agent) for the full amount of any drawing under any Letter of Credit by 12:00 p.m. Eastern time on the first Business Day following the Drawing Date, the Administrative Agent will promptly notify each Lender thereof, and the Borrowers shall be {N0289348 2 } 42

deemed to have requested that Revolving Credit Loans be made by the Lenders under the Base Rate Option to be disbursed on the first Business Day following the Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the Revolving Credit Commitment and subject to the conditions set forth in Section 7.2 [Each Loan or Letter of Credit] other than any notice requirements. Any notice given by the Administrative Agent or Issuing Lender pursuant to this Section 2.9.3.1 may be oral if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. 2.9.3.2 Each Lender shall upon any notice pursuant to Section 2.9.3.1 [Disbursements, Reimbursement] make available to the Administrative Agent for the account of the Issuing Lender an amount in immediately available funds equal to its Ratable Share of the amount of the drawing, whereupon the participating Lenders shall (subject to Section 2.9.3 [Disbursements; Reimbursement]) each be deemed to have made a Revolving Credit Loan under the Base Rate Option to the Borrowers in that amount. If any Lender so notified fails to make available to the Administrative Agent for the account of the Issuing Lender the amount of such Lender’s Ratable Share of such amount by no later than 2:00 p.m. Eastern time on the first Business Day following the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the first Business Day following the Drawing Date to the date on which such Lender makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three (3) days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Revolving Credit Loans under the Base Rate Option on and after the fourth day following the Drawing Date. The Administrative Agent and the Issuing Lender will promptly give notice (as described in Section 2.9.3.1 [Disbursements, Reimbursement] above) of the occurrence of the Drawing Date, but failure of the Administrative Agent or the Issuing Lender to give any such notice on the Drawing Date or in sufficient time to enable any Lender to effect such payment on the first Business Day following such Drawing Date shall not relieve such Lender from its obligation under this Section 2.9.3.2 [Disbursements, Reimbursement]. 2.9.3.3 With respect to any unreimbursed drawing that is not converted into Revolving Credit Loans under the Base Rate Option to the Borrowers in whole or in part as contemplated by Section 2.9.3.1, because of the Borrowers’ failure to satisfy the conditions set forth in Section 7.2 [Each Loan or Letter of Credit] other than any notice requirements, or for any other reason, the Borrowers shall be deemed to have incurred from the Issuing Lender a borrowing (each a “Letter of Credit Borrowing”) in the amount of such drawing thereof. Such Letter of Credit Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate per annum applicable to the Revolving Credit Loans under the Base Rate Option. Each Lender’s payment to the Administrative Agent for the account of the Issuing Lender pursuant to Section 2.9.3 [Disbursements, Reimbursement] shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing (each a “Participation Advance”) from such Lender in satisfaction of its participation obligation under this Section 2.9.3. {N0289348 2 } 43

2.9.4. Repayment of Participation Advances. 2.9.4.1 Upon (and only upon) receipt by the Administrative Agent for the account of the Issuing Lender of immediately available funds from the Borrowers (i) in reimbursement of any payment made by the Issuing Lender under the Letter of Credit with respect to which any Lender has made a Participation Advance to the Administrative Agent, or (ii) in payment of interest on such a payment made by the Issuing Lender under such a Letter of Credit, the Administrative Agent on behalf of the Issuing Lender will pay to each Lender, in the same funds as those received by the Administrative Agent, the amount of such Lender’s Ratable Share of such funds, except the Administrative Agent shall retain for the account of the Issuing Lender the amount of the Ratable Share of such funds of any Lender that did not make a Participation Advance in respect of such payment by the Issuing Lender. 2.9.4.2 If the Administrative Agent is required at any time to return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of any payment made by any Loan Party to the Administrative Agent for the account of the Issuing Lender pursuant to this Section in reimbursement of a payment made under any Letter of Credit or interest or fees thereon, each Lender shall, on demand of the Administrative Agent, forthwith return to the Administrative Agent for the account of the Issuing Lender the amount of its Ratable Share of any amounts so returned by the Administrative Agent plus interest thereon from the date such demand is made to the date such amounts are returned by such Lender to the Administrative Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time. 2.9.5. Documentation. Each Loan Party agrees to be bound by the terms of the Issuing Lender’s application and agreement for letters of credit and the Issuing Lender’s written regulations and customary practices relating to letters of credit, though such interpretation may be different from such Loan Party’s own. In the event of a conflict between such application or agreement and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct, the Issuing Lender shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following any Loan Party’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto. 2.9.6. Determinations to Honor Drawing Requests. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the Issuing Lender shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit. 2.9.7. Nature of Participation and Reimbursement Obligations. Each Lender’s obligation in accordance with this Agreement to make the Revolving Credit Loans or Participation Advances, as contemplated by Section 2.9.3 [Disbursements, Reimbursement], as a result of a drawing under a Letter of Credit, and the Obligations of the Borrowers to reimburse the Issuing Lender upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.9 under all circumstances, including the following circumstances: {N0289348 2 } 44

(i) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Issuing Lender or any of its Affiliates, the Borrowers or any other Person for any reason whatsoever, or which any Loan Party may have against the Issuing Lender or any of its Affiliates, any Lender or any other Person for any reason whatsoever; (ii) the failure of any Loan Party or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in Sections 2.1 [Revolving Credit Commitments], 2.5 [Revolving Credit Loan Requests; Swing Loan Requests], 2.6 [Making Revolving Credit Loans and Swing Loans; Etc.] or 7.2 [Each Loan or Letter of Credit] or as otherwise set forth in this Agreement for the making of a Revolving Credit Loan, it being acknowledged that such conditions are not required for the making of a Letter of Credit Borrowing and the obligation of the Lenders to make Participation Advances under Section 2.9.3 [Disbursements, Reimbursement]; (iii) any lack of validity or enforceability of any Letter of Credit; (iv) any claim of breach of warranty that might be made by any Loan Party or any Lender against any beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense or other right which any Loan Party or any Lender may have at any time against a beneficiary, successor beneficiary any transferee or assignee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), the Issuing Lender or its Affiliates or any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Loan Party or Subsidiaries of a Loan Party and the beneficiary for which any Letter of Credit was procured); (v) the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit, or the transport of any property or provision of services relating to a Letter of Credit, in each case even if the Issuing Lender or any of its Affiliates has been notified thereof; (vi) payment by the Issuing Lender or any of its Affiliates under any Letter of Credit against presentation of a demand, draft or certificate or other document which does not comply with the terms of such Letter of Credit; (vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, {N0289348 2 } 45

value or other characteristic of any property or services relating to a Letter of Credit; (viii) any failure by the Issuing Lender or any of its Affiliates to issue any Letter of Credit in the form requested by any Loan Party, unless the Issuing Lender has received written notice from such Loan Party of such failure within three Business Days after the Issuing Lender shall have furnished such Loan Party and the Administrative Agent a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice; (ix) any adverse change in the business, operations, properties, assets, condition (financial or otherwise) or prospects of any Loan Party or Subsidiaries of a Loan Party; (x) any breach of this Agreement or any other Loan Document by any party thereto; (xi) the occurrence or continuance of an Insolvency Proceeding with respect to any Loan Party; (xii) the fact that an Event of Default or a Potential Default shall have occurred and be continuing; (xiii) the fact that the Expiration Date shall have passed or this Agreement or the Commitments hereunder shall have been terminated; and (xiv) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. 2.9.8. Indemnity. Each Borrower hereby agrees to protect, indemnify, pay and save harmless the Issuing Lender and any of its Affiliates that has issued a Letter of Credit from and against any and all claims, demands, liabilities, damages, penalties, interest, judgments, losses, costs, charges and expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of internal counsel) which the Issuing Lender or any of its Affiliates may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit, other than as a result of (A) the gross negligence or willful misconduct of the Issuing Lender as determined by a final non-appealable judgment of a court of competent jurisdiction or (B) the wrongful dishonor by the Issuing Lender or any of Issuing Lender’s Affiliates of a proper demand for payment made under any Letter of Credit, except if such dishonor resulted from any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or Official Body. For the avoidance of doubt, this Section 2.9.8 shall not be interpreted to refer to Taxes, which are addressed elsewhere herein. 2.9.9. Liability for Acts and Omissions. As between any Loan Party and the Issuing Lender, or the Issuing Lender’s Affiliates, such Loan Party assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lender shall not be responsible for any of the following, including any losses or damages to any Loan Party or {N0289348 2 } 46

other Person or property relating therefrom: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if the Issuing Lender or its Affiliates shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Loan Party against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Loan Party and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Issuing Lender or its Affiliates, as applicable, including any act or omission of any Official Body, and none of the above shall affect or impair, or prevent the vesting of, any of the Issuing Lender’s or its Affiliates rights or powers hereunder. Nothing in the preceding sentence shall relieve the Issuing Lender from liability for the Issuing Lender’s gross negligence or willful misconduct in connection with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall the Issuing Lender or its Affiliates be liable to any Loan Party for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit. Without limiting the generality of the foregoing, the Issuing Lender and each of its Affiliates (i) may rely on any oral or other communication believed in good faith by the Issuing Lender or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by the Issuing Lender or its Affiliate; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on the Issuing Lender or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each an “Order”) and honor any drawing in connection with any Letter of Credit that {N0289348 2 } 47

is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit. In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by the Issuing Lender or its Affiliates under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith, shall not put the Issuing Lender or its Affiliates under any resulting liability to the Borrowers or any Lender. 2.9.10. Issuing Lender Reporting Requirements. Each Issuing Lender shall, on the first Business Day of each month, provide to Administrative Agent and Borrowers a schedule of the Letters of Credit issued by it, in form and substance satisfactory to Administrative Agent, showing the date of issuance of each Letter of Credit, the account party, the original face amount (if any), and the expiration date of any Letter of Credit outstanding at any time during the preceding month, and any other information relating to such Letter of Credit that the Administrative Agent may request. 2.10 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: (i) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.3 [Unused Line Fees]; (ii) the Commitment and outstanding Loans of such Defaulting Lender shall not be included in determining whether the Required Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 12.1 [Modifications, Amendments or Waivers]); provided, that this clause (ii) shall not apply to the vote of a Defaulting Lender in the case of an amendment, waiver or other modification requiring the consent of such Lender or each Lender directly affected thereby; (iii) if any Swing Loans are outstanding or any Letter of Credit Obligations exist at the time such Lender becomes a Defaulting Lender, then: (a) all or any part of the outstanding Swing Loans and Letter of Credit Obligations of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Ratable Shares but only to the extent that (x) the Revolving Facility Usage does not exceed the total of all non-Defaulting Lenders’ Revolving Credit Commitments, and (y) no Potential Default or Event of Default has occurred and is continuing at such time; (b) if the reallocation described in clause (a) above cannot, or can only partially, be effected, the Borrowers shall within one Business Day following notice by the Administrative Agent (x) first, prepay such outstanding Swing Loans, and (y) second, cash collateralize for the benefit of the Issuing Lender the Borrowers’ obligations corresponding to such Defaulting Lender’s Letter of Credit Obligations (after giving effect to any partial reallocation pursuant to clause (a) above) in a deposit account held at the Administrative Agent for so long as such Letter of Credit Obligations are outstanding; {N0289348 2 } 48

(c) if the Borrowers cash collateralize any portion of such Defaulting Lender’s Letter of Credit Obligations pursuant to clause (b) above, the Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.9.2 [Letter of Credit Fees] with respect to such Defaulting Lender’s Letter of Credit Obligations during the period such Defaulting Lender’s Letter of Credit Obligations are cash collateralized; (d) if the Letter of Credit Obligations of the non-Defaulting Lenders are reallocated pursuant to clause (a) above, then the fees payable to the Lenders pursuant to Section 2.9.2 [Letter of Credit Fees] shall be adjusted in accordance with such non-Defaulting Lenders’ Ratable Share; and (e) if all or any portion of such Defaulting Lender’s Letter of Credit Obligations are neither reallocated nor cash collateralized pursuant to clause (a) or (b) above, then, without prejudice to any rights or remedies of the Issuing Lender or any other Lender hereunder, all Letter of Credit Fees payable under Section 2.9.2 [Letter of Credit Fees] with respect to such Defaulting Lender’s Letter of Credit Obligations shall be payable to the Issuing Lender (and not to such Defaulting Lender) until and to the extent that such Letter of Credit Obligations are reallocated and/or cash collateralized; and (iv) so long as such Lender is a Defaulting Lender, FNB shall not be required to fund any Swing Loans and the Issuing Lender shall not be required to issue, amend or increase any Letter of Credit, unless such Issuing Lender is satisfied that the related exposure and the Defaulting Lender’s then outstanding Letter of Credit Obligations will be 100% covered by the Revolving Credit Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrowers in accordance with Section 2.10(iii), and participating interests in any newly made Swing Loan or any newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.10(iii) (and such Defaulting Lender shall not participate therein). If (i) a Bankruptcy Event with respect to a parent company of any Lender shall occur following the date hereof and for so long as such event shall continue, or (ii) FNB or the Issuing Lender has a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, FNB shall not be required to fund any Swing Loan and the Issuing Lender shall not be required to issue, amend or increase any Letter of Credit, unless FNB or the Issuing Lender, as the case may be, shall have entered into arrangements with the Borrowers or such Lender, satisfactory to FNB or the Issuing Lender, as the case may be, to defease any risk to it in respect of such Lender hereunder. In the event that the Administrative Agent, the Borrower, FNB and the Issuing Lender agree in writing that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Administrative Agent will so notify the parties hereto, and the Ratable Share of the Swing Loans and Letter of Credit Obligations of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment, and on such date such Lender shall purchase at par such of the Loans of the other Lenders (other than Swing Loans) as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Ratable Share. {N0289348 2 } 49

3. TERM LOANS 3.1 Term Loan Commitments. Subject to the terms and conditions hereof, and relying upon the representations and warranties herein set forth, each Lender severally agrees to make a term loan (the “Term Loan”) to the Borrowers on the Closing Date in such principal amount as the Borrowers shall request up to, but not exceeding such Lender’s Term Loan Commitment. 3.2 Nature of Lenders’ Obligations with Respect to Term Loans; Repayment Terms. The obligations of each Lender to make Term Loans to the Borrowers shall be in the proportion that such Lender’s Term Loan Commitment bears to the Term Loan Commitments of all Lenders to the Borrowers, but each Lender’s Term Loan to the Borrowers shall never exceed its Term Loan Commitment. The failure of any Lender to make a Term Loan shall not relieve any other Lender of its obligations to make a Term Loan nor shall it impose any additional liability on any other Lender hereunder. The Lenders shall have no obligation to make Term Loans hereunder after the Closing Date. The Term Loan Commitments are not revolving credit commitments, and the Borrowers shall not have the right to borrow, repay and reborrow under Section 3.1 [Term Loan Commitments]. The principal balance of the Term Loans shall be due and payable in consecutive quarterly installments determined by, and as set forth in, the table set forth below (subject, however, to adjustment for voluntary prepayments as set forth in Section 5.6 [Voluntary Prepayments] and mandatory prepayments as set forth in Section 5.7 [Mandatory Prepayments]): Amount of Term Date of Payment of Installment Loan Repayment Year 1 December 31, 2020 $1,750,000.00 March 31, 2021 $1,750,000.00 June 30, 2021 $1,750,000.00 September 30, 2021 $1,750,000.00 Year 2 December 31, 2021 $1,750,000.00 March 31, 2022 $1,750,000.00 June 30, 2022 $1,750,000.00 September 30, 2022 $1,750,000.00 Year 3 December 31, 2022 $2,187,500.00 March 31, 2023 $2,187,500.00 June 30, 2023 $2,187,500.00 September 30, 2023 $2,187,500.00 Year 4 December 31, 2023 $2,187,500.00 March 31, 2024 $2,187,500.00 June 30, 2024 $2,187,500.00 September 30, 2024 $2,187,500.00 {N0289348 2 } 50

Year 5 December 31, 2024 $2,187,500.00 March 31, 2025 $2,187,500.00 June 30, 2025 $2,187,500.00 Payments of principal shall be due on the last day of each calendar quarter, beginning on December 31, 2020, as set forth above, and continuing until the Expiration Date when the entire unpaid principal balance hereof and accrued interest thereon shall be due and payable in full. 4. INTEREST RATES 4.1 Interest Rate Options. The Borrowers shall pay interest in respect of the outstanding unpaid principal amount of the Loans as selected by the Administrative Borrower from the Base Rate Option or LIBOR Rate Option set forth below applicable to the Loans, it being understood that, subject to the provisions of this Agreement, the Administrative Borrower may select different Interest Rate Options and different Interest Periods to apply simultaneously to the Loans comprising different Borrowing Tranches and may convert to or renew one or more Interest Rate Options with respect to all or any portion of the Loans comprising any Borrowing Tranche; provided that there shall not be at any one time outstanding more than six (6) Borrowing Tranches in the aggregate among all of the Loans and provided further that if an Event of Default or Potential Default exists and is continuing, neither the Administrative Borrower nor any other Borrower may request, convert to, or renew the LIBOR Rate Option for any Loans and the Required Lenders may demand that all existing Borrowing Tranches bearing interest under the LIBOR Rate Option shall be converted immediately to the Base Rate Option, subject to the obligation of the Borrowers to pay any indemnity under Section 5.10 [Indemnity] in connection with such conversion. If at any time the designated rate applicable to any Loan made by any Lender exceeds such Lender’s highest lawful rate, the rate of interest on such Lender’s Loan shall be limited to such Lender’s highest lawful rate. 4.1.1. Revolving Credit Interest Rate Options; Swing Line Interest Rate. The Administrative Borrower shall have the right to select from the following Interest Rate Options applicable to the Revolving Credit Loans: (i) Revolving Credit Base Rate Option: A fluctuating rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such interest rate to change automatically from time to time effective as of the effective date of each change in the Base Rate; or (ii) Revolving Credit LIBOR Rate Option: A rate per annum (computed on the basis of a year of 360 days and actual days elapsed) equal to the LIBOR Rate as determined for each applicable Interest Period plus the Applicable Margin. Subject to Section 4.3 [Interest After Default], only the Base Rate Option applicable to Revolving Credit Loans shall apply to the Swing Loans. {N0289348 2 } 51

4.1.2. Term Loan Interest Rate Options. The Administrative Borrower shall have the right to select from the following Interest Rate Options applicable to the Term Loans: (i) Term Loan Base Rate Option: A fluctuating rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such interest rate to change automatically from time to time effective as of the effective date of each change in the Base Rate; or (ii) Term Loan LIBOR Rate Option: A rate per annum (computed on the basis of a year of 360 days and actual days elapsed) equal to the LIBOR Rate plus the Applicable Margin. 4.1.3. Rate Quotations. The Administrative Borrower may call the Administrative Agent on or before the date on which a Loan Request is to be delivered to receive an indication of the rates then in effect, but it is acknowledged that such projection shall not be binding on the Administrative Agent or the Lenders nor affect the rate of interest which thereafter is actually in effect when the election is made. 4.2 Interest Periods. At any time when the Administrative Borrower shall select, convert to or renew a LIBOR Rate Option, the Administrative Borrower shall notify the Administrative Agent thereof at least three (3) Business Days prior to the effective date of such LIBOR Rate Option by delivering a Loan Request. The notice shall specify an Interest Period during which such Interest Rate Option shall apply. Notwithstanding the preceding sentence, the following provisions shall apply to any selection of, renewal of, or conversion to a LIBOR Rate Option: 4.2.1. Amount of Borrowing Tranche. Each Borrowing Tranche of Loans under the LIBOR Rate Option shall be in integral multiples of, and not less than, the respective amounts set forth in Section 2.5.1 [Revolving Credit Loan Requests]; and 4.2.2. Renewals. In the case of the renewal of a LIBOR Rate Option at the end of an Interest Period, the first day of the new Interest Period shall be the last day of the preceding Interest Period, without duplication in payment of interest for such day. 4.3 Interest After Default. To the extent permitted by Law, upon the occurrence of an Event of Default and until such time such Event of Default shall have been cured or waived, and at the discretion of the Administrative Agent or upon written demand by the Required Lenders to the Administrative Agent: 4.3.1. Letter of Credit Fees, Interest Rate. The Letter of Credit Fees and the rate of interest for each Loan otherwise applicable pursuant to Section 2.9.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate Options], respectively, shall be increased by 2.0% per annum; 4.3.2. Other Obligations. Each other Obligation hereunder if not paid when due shall bear interest at a rate per annum equal to the sum of the rate of interest applicable to Revolving Credit Loans under the Base Rate Option plus an additional 2.0% per annum from the time such Obligation becomes due and payable and until it is Paid In Full; and {N0289348 2 } 52

4.3.3. Acknowledgment. The Borrowers acknowledge that the increase in rates referred to in this Section 4.3 reflects, among other things, the fact that such Loans or other amounts have become a substantially greater risk given their default status and that the Lenders are entitled to additional compensation for such risk; and all such interest shall be payable by Borrowers upon demand by Administrative Agent. The Administrative Agent will notify the Borrowers if the rate of interest is increased pursuant to this Section 4.3. 4.4 LIBOR Rate Unavailable; Illegality; Increased Costs; Deposits Not Available. LIBOR Unavailability. Notwithstanding anything to the contrary, in the event that the Administrative Agent shall have reasonably determined in good faith that U.S. Dollar deposits in the principal amounts of the Loans are not generally available in the London interbank market, or that the Administrative Agent has been notified in writing by the Required Lenders that the rates at which such U.S. Dollar deposits are being offered will not adequately and fairly in good faith reflect the cost to the Required Lenders of making or maintaining Loans at LIBOR, or that reasonable means do not exist for ascertaining LIBOR, the Administrative Agent shall, as soon as practicable thereafter, notify the Borrower and the Lenders of such determination (a “LIBOR Unavailability Notice”). The Administrative Agent may rescind any such LIBOR Unavailability Notice in the event that the circumstances giving rise to such notice no longer exist (such notice to be provided by the Administrative Agent promptly upon written notice of the Majority Lenders that the circumstances giving rise to such LIBOR Unavailability Notice have ceased to exist). 4.4.2. Benchmark Replacement Setting. (i) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then, (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, in connection with a Benchmark Transition Event, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, or in connection with an Early Opt-in Election, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Borrowers without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders Comprising Required Lenders. (ii) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Administrative Agent will {N0289348 2 } 53

have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. (iii) Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Administrative Borrower of (i) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of any tenor of Term SOFR pursuant to Section 4.4.2(iv) [Unavailability of Tenor of Benchmark] below, and (v) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 4.4.2 [Benchmark Replacement Setting] including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to Section 4.4.2 [Benchmark Replacement Setting]. (iv) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor. (v) Benchmark Unavailability Period. Upon the Administrative Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Administrative Borrower may revoke any request for a borrowing of, conversion to or continuation of any Loan or Loans to be made, converted or continued under the LIBOR Rate Option during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to the Base Rate Option. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate. {N0289348 2 } 54

4.4.3. Illegality; Increased Costs; Deposits Not Available. If at any time any Lender shall have determined that: (i) the making, maintenance or funding of any Loan to which a LIBOR Rate Option applies has been made impracticable or unlawful by compliance by such Lender in good faith with any Law or any interpretation or application thereof by any Official Body or with any request or directive of any such Official Body (whether or not having the force of Law), or (ii) such LIBOR Rate Option will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any such Loan, or (iii) after making all reasonable efforts, deposits of the relevant amount in Dollars for the relevant Interest Period for a Loan, or to banks generally, to which a LIBOR Rate Option applies, respectively, are not available to such Lender with respect to such Loan, or to banks generally, in the interbank Eurodollar market, then the Administrative Agent shall have the rights specified in Section 4.4.4 [Administrative Agent’s and Lender’s Rights]. 4.4.4. Administrative Agent’s and Lender’s Rights. In the case of any event specified in Section 4.4.1 [LIBOR Unavailability] above, the Administrative Agent shall promptly so notify the Lenders and the Borrowers thereof, and in the case of an event specified in Section 4.4.3 [Illegality; Increased Costs; Deposits Not Available] above, such Lender shall promptly so notify the Administrative Agent and endorse a certificate to such notice as to the specific circumstances of such notice, and the Administrative Agent shall promptly send copies of such notice and certificate to the other Lenders and the Borrowers. Upon such date as shall be specified in such notice (which shall not be earlier than the date such notice is given), the obligation of (A) the Lenders, in the case of such notice given by the Administrative Agent, or (B) such Lender, in the case of such notice given by such Lender, to allow the Borrowers to select, convert to or renew a LIBOR Rate Option shall be suspended until the Administrative Agent shall have later notified the Borrowers, or such Lender shall have later notified the Administrative Agent, of the Administrative Agent’s or such Lender’s, as the case may be, determination that the circumstances giving rise to such previous determination no longer exist. If at any time the Administrative Agent makes a determination under Section 4.4.1 [Unascertainable] and the Administrative Borrower has previously notified the Administrative Agent of its selection of, conversion to or renewal of a LIBOR Rate Option and such Interest Rate Option has not yet gone into effect, such notification shall be deemed to provide for selection of, conversion to or renewal of the Base Rate Option otherwise available with respect to such Loans. If any Lender notifies the Administrative Agent of a determination under Section 4.4.3 [Illegality; Increased Costs; Deposits Not Available], the Borrowers shall, subject to the Borrowers’ indemnification Obligations under Section 5.10 [Indemnity], as to any Loan of the Lender to which a LIBOR Rate Option applies, on the date specified in such notice either convert such Loan to the Base Rate Option otherwise available with respect to such Loan or prepay such Loan in accordance with Section 5.6 [Voluntary Prepayments]. Absent due notice {N0289348 2 } 55

from the Borrowers of conversion or prepayment, such Loan shall automatically be converted to the Base Rate Option otherwise available with respect to such Loan upon such specified date. 4.5 Selection of Interest Rate Options. If the Borrowers fail to select a new Interest Period to apply to any Borrowing Tranche of Loans under the LIBOR Rate Option at the expiration of an existing Interest Period applicable to such Borrowing Tranche in accordance with the provisions of Section 4.2 [Interest Periods], the Borrowers shall be deemed to have converted such Borrowing Tranche to the Base Rate Option, as applicable to Revolving Credit Loans or Term Loans as the case may be, commencing upon the last day of the existing Interest Period. 5. PAYMENTS 5.1 Payments. All payments and prepayments to be made in respect of principal, interest, Unused Line Fees, Letter of Credit Fees, Arrangement Fee, the Agency Fee, the Upfront Fee or other fees or amounts due from the Borrowers hereunder shall be payable prior to 11:00 a.m. Eastern time on the date when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Borrowers, and without set-off, counterclaim or other deduction of any nature (except as expressly permitted by Section 5.9 [Taxes]), and an action therefor shall immediately accrue. Such payments shall be made to the Administrative Agent at the Principal Office for the account of FNB with respect to the Swing Loans and for the ratable accounts of the Lenders with respect to the Revolving Credit Loans or Term Loans in U.S. Dollars and in immediately available funds, and the Administrative Agent shall promptly distribute such amounts to the Lenders in immediately available funds; provided that in the event payments are received by 11:00 a.m. Eastern time by the Administrative Agent with respect to the Loans and such payments are not distributed to the Lenders on the same day received by the Administrative Agent, the Administrative Agent shall pay the Lenders the Federal Funds Effective Rate with respect to the amount of such payments for each day held by the Administrative Agent and not distributed to the Lenders. The Administrative Agent’s and each Lender’s statement of account, ledger or other relevant record shall, in the absence of manifest error, be conclusive as the statement of the amount of principal of and interest on the Loans and other amounts owing under this Agreement. 5.2 Pro Rata Treatment of Lenders. Each borrowing of Revolving Credit Loans shall be allocated to each Lender according to its Ratable Share, and each selection of, conversion to or renewal of any Interest Rate Option and each payment or prepayment by the Borrower with respect to principal, interest, Unused Line Fees and Letter of Credit Fees (but excluding the Arrangement Fee, the Agency Fee, the Upfront Fee and the Issuing Lender’s fronting fee) shall (except as otherwise may be provided with respect to a Defaulting Lender and except as provided in Section 4.4.4 [Administrative Agent’s and Lender’s Rights] in the case of an event specified in Section 4.4 [LIBOR Rate Unascertainable; Etc.], 5.6.2 [Replacement of a Lender] or 5.8 [Increased Costs]) be payable ratably among the Lenders entitled to such payment in accordance with the amount of principal, interest, Unused Line Fees and Letter of Credit Fees, as set forth in this Agreement. Notwithstanding any of the foregoing, each borrowing or payment or prepayment by the Borrowers of principal, interest, fees or other amounts from the Borrowers with respect to Swing Loans shall be made by or to FNB according to Section 2.6.5 [Borrowings to Repay Swing Loans]. {N0289348 2 } 56

5.3 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff, counterclaim or banker’s lien, by receipt of voluntary payment, by realization upon security, or by any other non-pro rata source, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than the pro-rata share of the amount such Lender is entitled thereto, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, 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 and other amounts owing them, 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, together with interest or other amounts, if any, required by Law (including court order) to be paid by the Lender or the holder making such purchase; and (ii) the provisions of this Section 5.3 shall not be construed to apply to (x) any payment made by the Loan Parties pursuant to and in accordance with the express terms of the Loan Documents or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or Participation Advances to any assignee or participant, other than to the Borrowers or any Subsidiary thereof (as to which the provisions of this Section 5.3 shall apply). Each Loan Party 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 each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation. 5.4 Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Lender hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Lender, as the case may be, the amount due. In such event, if the Borrowers have not in fact made such payment, then each of the Lenders or the Issuing Lender, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the Issuing 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. 5.5 Interest Payment Dates. Interest on Loans to which the Base Rate Option applies shall be due and payable in arrears on each Payment Date. Interest on Loans to which the {N0289348 2 } 57

LIBOR Rate Option applies shall be due and payable on the last day of each Interest Period for those Loans and, if such Interest Period is longer than three (3) Months, also on the 90th day of such Interest Period. Interest on mandatory prepayments of principal under Section 5.7 [Mandatory Prepayments] shall be due on the date such mandatory prepayment is due. Interest on the principal amount of each Loan or other monetary Obligation shall be due and payable on demand after such principal amount or other monetary Obligation becomes due and payable (whether on the stated Expiration Date, upon acceleration or otherwise). 5.6 Voluntary Prepayments. 5.6.1. Right to Prepay. The Borrowers shall have the right at their option from time to time to prepay the Loans in whole or part without premium or penalty (except as provided in Section 5.6.2 [Replacement of a Lender] below, in Section 5.8 [Increased Costs] and Section 5.10 [Indemnity]). Whenever the Borrowers desire to prepay any part of the Loans, the Administrative Borrower shall provide a prepayment notice to the Administrative Agent by 1:00 p.m. Eastern time at least one (1) Business Day prior to the date of prepayment of the Revolving Credit Loans or Term Loans or no later than 1:00 p.m. Eastern time on the date of prepayment of Swing Loans, setting forth the following information: (a) the date, which shall be a Business Day, on which the proposed prepayment is to be made; (b) a statement indicating the application of the prepayment between the Revolving Credit Loans, Term Loans and Swing Loans; (c) a statement indicating the application of the prepayment between Loans to which the Base Rate Option applies and Loans to which the LIBOR Rate Option applies; and (d) the total principal amount of such prepayment, which shall not be less than $100,000 for any Swing Loan or $500,000 for any Term Loan. All prepayment notices shall be irrevocable. The principal amount of the Loans for which a prepayment notice is given, together with interest on such principal amount except with respect to Loans to which the Base Rate Option applies, shall be due and payable on the date specified in such prepayment notice as the date on which the proposed prepayment is to be made. All Term Loan prepayments permitted pursuant to this Section 5.6.1 [Right to Prepay] shall be applied to unpaid installments of principal of the Term Loans as directed by the Administrative Borrower and any principal amount of the Term Loan prepaid may not be reborrowed. Notwithstanding the application of any prepayments as directed by the Administrative Borrower pursuant to this Section 5.6.1 [Right to Prepay], for purposes of calculating any applicable Fixed Charge Coverage Ratio, such prepayments will be deemed to have been applied in accordance with the requirements for the application of mandatory Term Loan prepayments pursuant to Section 5.7 [Mandatory Prepayments]. Except as provided in Section 4.4.4 [Administrative Agent’s and Lender’s Rights], if the Borrowers prepay a Loan but fail to specify the applicable Borrowing Tranche which the Borrowers are prepaying, the prepayment shall be applied (i) first to Revolving Credit Loans and then to Term Loans; and (ii) after giving effect to the allocations in clause (i) above and in the preceding sentence, next to Loans to which the Base Rate Option applies, then to Loans to which the LIBOR Rate Option {N0289348 2 } 58

applies. Any prepayment hereunder shall be subject to the Borrowers’ Obligation to indemnify the Lenders under Section 5.10 [Indemnity]. 5.6.2. Replacement of a Lender. In the event any Lender (i) gives notice under Section 4.4 [LIBOR Rate Unascertainable, Etc.], (ii) requests compensation under Section 5.8 [Increased Costs], or requires the Borrower to pay any Indemnified Taxes or additional amount to any Lender or any Official Body for the account of any Lender pursuant to Section 5.9 [Taxes], (iii) is a Defaulting Lender, (iv) becomes subject to the control of an Official Body (other than normal and customary supervision), or (v) is a Non-Consenting Lender referred to in Section 12.1 [Modifications, Amendments or Waivers], then in any such event the Borrowers may, at their sole expense, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.8 [Successors and Assigns]), all of its interests, rights (other than existing rights to payments pursuant to Sections 5.8 [Increased Costs] or 5.9 [Taxes]) and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that: (i) the Borrowers shall have paid to the Administrative Agent the assignment fee specified in Section 12.8 [Successors and Assigns]; (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and Participation Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.10 [Indemnity]) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts); (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.8.1 [Increased Costs Generally] or payments required to be made pursuant to Section 5.9 [Taxes], such assignment will result in a reduction in such compensation or payments thereafter; and (iv) such assignment does not conflict with applicable Law. A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply. 5.6.3. Designation of a Different Lending Office. If any Lender requests compensation under Section 5.8 [Increased Costs], or the Borrowers are or will be required to pay any Indemnified Taxes or additional amounts to any Lender or any Official Body for the account of any Lender pursuant to Section 5.9 [Taxes], then such Lender shall (at the request of the Borrowers) 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 reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.8 [Increased Costs] or Section 5.9 [Taxes], as the case may be, in the future, and (ii) would not subject such {N0289348 2 } 59

Lender to any material unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 5.7 Mandatory Prepayments. 5.7.1. Sale of Assets. If on any date the Borrowers or any of their Subsidiaries shall receive net cash proceeds from (i) any Asset Sale, and the net cash proceeds of such Asset Sale or the aggregate net cash proceeds of all Asset Sales in any fiscal year exceeds $250,000, or (ii) any Recovery Event, and the net cash proceeds of such Recovery Event or the aggregate net cash proceeds of all Recovery Events during any fiscal year exceeds $250,000, then all of such net cash proceeds (and not merely such excess) shall be applied five (5) Business Days after such date to the prepayment of the Term Loans as follows: payments will first be applied pro rata to the unpaid installments of principal of the Term Loans, without premium or penalty (subject to payment of breakage costs in the case of a prepayment of Loans for which a LIBOR Rate Option applies other than on the last day of the relevant interest period, or any other provision contained in this Agreement) and then to reduce the outstanding Revolving Facility Usage, if any. The amount of any mandatory prepayments applied to principal of the Term Loans under this Section 5.7.1 [Sale of Assets] may not be reborrowed. 5.7.2. Maximum Borrowing Base Exceeded. Whenever the outstanding Revolving Facility Usage exceed the Maximum Borrowing Base, the Borrowers shall make, within one (1) Business Day after the Borrowers learn of such excess and whether or not the Administrative Agent has given notice to such effect, a mandatory prepayment of principal equal to the excess of the outstanding principal balance of the Revolving Credit Loans over the Maximum Borrowing Base, together with accrued interest on such principal amount. If after such prepayment the Revolving Facility Usage still exceeds the Maximum Borrowing Base, the Borrowers shall cash collateralize such excess amount by pledging and depositing with or delivering to Administrative Agent, for the benefit of each of the Lenders, as collateral for such excess amount, cash or deposit account balances pursuant to documentation satisfactory to Administrative Agent, which such cash collateral shall be maintained in blocked, non-interest bearing deposit accounts at the Administrative Agent. The Borrowers hereby grant to Administrative Agent, for the benefit of each of the Lenders, a security interest in all cash collateral pledged pursuant to this Section 5.7.2 [Maximum Borrowing Base Exceeded]. 5.7.3. Excess Cash Flow. Within ten (10) calendar days of delivery of the Holdings’ audited consolidated year-end financial statements, but in any event no later than one hundred twenty (120) calendar days after the end of each fiscal year commencing with the fiscal year ending September 30, 2021, and continuing through the expiration of the term hereof, the Borrowers shall make a mandatory prepayment of principal on the Term Loans (“Mandatory Prepayment of Excess Cash Flow”) in an amount equal to: (a) 75% of Excess Cash Flow for the immediately preceding fiscal year if, at the time of determination, the Total Leverage Ratio of the Borrowers is greater than or equal to 2.5 to1.0; {N0289348 2 } 60

(b) 50% of Excess Cash Flow for the immediately preceding fiscal year if, at the time of determination, the Total Leverage Ratio of the Borrowers is less than 2.5:1.0 but greater than or equal to 1.5 to 1.0; and (c) 0% of Excess Cash Flow for the immediately preceding fiscal year if, at the time of determination, the Total Leverage Ratio of the Borrowers is less than 1.5 to1.0. Each Mandatory Prepayment of Excess Cash Flow (i) shall be reduced by the aggregate principal amount of all voluntary Term Loan prepayments made during the immediately preceding fiscal year, and (ii) shall be applied pro rata to the unpaid installments of principal of the Term Loans. To the extent that a Mandatory Prepayment of Excess Cash Flow exceeds the outstanding principal amount of the Term Loans, such prepayment shall be limited to the amount necessary to prepay the Term Loans in full. The amount of any Mandatory Prepayment of Excess Cash Flow applied to principal of the Term Loan may not be reborrowed. 5.7.4. Equity Issuance; Indebtedness. Within five (5) Business Days of: (i) the issuance by Holdings of any Equity Interests (other than an Excluded Equity Issuance), and continuing through the expiration of the term hereof, the Borrowers shall make a mandatory prepayment of principal on the Term Loans in an amount equal to the percentage set forth below of the net cash proceeds of the issuance of such Equity Interests, together with accrued interest on such principal amount (each, a “Mandatory Prepayment of Equity”): (a) 50% of such net cash proceeds if, at the time of issuance, the Total Leverage Ratio is equal to or greater than 2.0 to 1.0; and (b) 25% of such net cash proceeds if, at the time of issuance, the Total Leverage Ratio is less than 2.0 to 1.0. (ii) the issuance by Holdings or any Borrower of any Indebtedness, other than any Indebtedness permitted under Section 8.2.1 [Indebtedness], and continuing through the expiration of the term hereof, the Borrowers shall make a mandatory prepayment of principal on the Term Loans in an amount equal to 100% of the net cash proceeds of the issuance of such Indebtedness, as applicable, together with accrued interest on such principal amount (each, a “Mandatory Prepayment of Indebtedness”). (iii) Each Mandatory Prepayment of Equity or Mandatory Prepayment of Indebtedness shall be applied pro rata to the unpaid installments of principal of the Term Loans. To the extent that a Mandatory Prepayment of Equity or Mandatory Prepayment of Indebtedness exceeds the outstanding principal amount of the Term Loans, such prepayment shall be limited to the amount necessary to prepay the Term Loans in full. The amount of any Mandatory Prepayment of Equity or Mandatory Prepayment of Indebtedness applied to principal of the Term Loan may not be reborrowed. 5.7.5. Application Among Interest Rate Options. All prepayments required pursuant to this Section 5.7 [Mandatory Prepayments] shall first be applied among the Interest {N0289348 2 } 61

Rate Options to the principal amount of the Loans subject to the Base Rate Option, then to Loans subject to a LIBOR Rate Option. In accordance with Section 5.10 [Indemnity], the Borrowers shall indemnify the Lenders for any loss or expense, including loss of margin, incurred with respect to any such prepayments applied against Loans subject to a LIBOR Rate Option on any day other than the last day of the applicable Interest Period. 5.8 Increased Costs. 5.8.1. Increased Costs Generally. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate) or the Issuing Lender; (ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or (iii) impose on any Lender, the Issuing Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Lender, the Issuing Lender or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, the Issuing Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, the Issuing Lender or other Recipient, the Borrowers will pay to such Lender, the Issuing Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered. 5.8.2. Capital Requirements. If any Lender or the Issuing Lender determines that any Change in Law affecting such Lender or the Issuing Lender or any lending office of such Lender or such Lender’s or the Issuing Lender’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Lender’s capital or on the capital of such Lender’s or the Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swing Loans held by, such Lender, or the Letters of Credit issued by the Issuing Lender, to a level below that which such Lender or the Issuing Lender or such Lender’s or the Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Lender’s policies and the policies of such Lender’s or the Issuing Lender’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to {N0289348 2 } 62

such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender or such Lender’s or the Issuing Lender’s holding company for any such reduction suffered. 5.8.3. Certificates for Reimbursement; Repayment of Outstanding Loans; Borrowing of New Loans. A certificate of a Lender or the Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or the Issuing Lender or its holding company, as the case may be, as specified in Sections 5.8.1 [Increased Costs Generally] or 5.8.2 [Capital Requirements] and delivered to the Borrowers shall be conclusive absent manifest error. The Borrowers shall pay such Lender or the Issuing Lender, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof. 5.8.4. Delay in Requests. Failure or delay on the part of any Lender or the Issuing Lender to demand compensation pursuant to this Section 5.8 [Increased Costs] shall not constitute a waiver of such Lender’s or the Issuing Lender’s right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender or the Issuing Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or the Issuing Lender, as the case may be, notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine (9) month period referred to above shall be extended to include the period of retroactive effect thereof). 5.9 Taxes. 5.9.1. Issuing Lender. For purposes of this Section 5.9, the term “Lender” includes the Issuing Lender and the term “applicable Law” includes FATCA. 5.9.2. Payments Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be 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 Official Body in accordance with applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party 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 5.9 [Taxes]) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. 5.9.3. Payment of Other Taxes by the Loan Parties. Without duplication of other amounts payable by a Loan Party, the Loan Parties shall timely pay to the relevant Official Body in accordance with applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. {N0289348 2 } 63

5.9.4. Indemnification by the Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient, within ten (10) calendar 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 5.9 [Taxes]) 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 Official Body. A certificate as to the amount of such payment or liability delivered to the Borrowers 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. 5.9.5. Indemnification by the Lenders for Taxes. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of any of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.8.4 [Participations] 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 Official Body. 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 set off 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 Section 5.9.5 [Indemnification by the Lenders for Taxes]. 5.9.6. Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to an Official Body pursuant to this Section 5.9 [Taxes], such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Official Body evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 5.9.7. Status of Recipients. (i) Any Recipient 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 Borrowers and the Administrative Agent, at the time or times reasonably requested by the Borrowers or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrowers or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Recipient, if reasonably requested by the Borrowers or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrowers or the Administrative Agent as will enable the Borrowers or the Administrative Agent to determine whether or not such Recipient is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two {N0289348 2 } 64

sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.9.7(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Recipient’s reasonable judgment such completion, execution or submission would subject such Recipient to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Recipient. (ii) Without limiting the generality of the foregoing, in the event that each Borrower is a U.S. Borrower, (A) any Recipient that is a U.S. Person shall deliver to the Borrowers and the Administrative Agent on or prior to the date on which such Recipient becomes a Recipient under this Agreement (and from time to time thereafter upon the reasonable request of the Borrowers or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Recipient is exempt from U.S. federal backup withholding tax; (B) any Foreign Recipient shall, to the extent it is legally entitled to do so, deliver to the Borrowers 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 Recipient becomes a Recipient under this Agreement (and from time to time thereafter upon the reasonable request of the Borrowers or the Administrative Agent), whichever of the following is applicable: (i) in the case of a Foreign Recipient 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, executed originals of 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 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; (iii) executed originals of IRS Form W-8ECI; (iv) in the case of a Foreign Recipient 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 5.9.7(A) to the effect that such Foreign Recipient is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of a Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or (v) to the extent a Foreign Recipient is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit 5.9.7(B) or Exhibit 5.9.7(C), IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Recipient is a partnership and one or more direct or indirect partners of such Foreign Recipient are claiming the portfolio interest {N0289348 2 } 65

exemption, such Foreign Recipient may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit 5.9.7(D) on behalf of each such direct and indirect partner; (C) any Foreign Recipient shall, to the extent it is legally entitled to do so, deliver to the Borrowers 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 Recipient becomes a Recipient under this Agreement (and from time to time thereafter upon the reasonable request of the Borrowers or the Administrative Agent), executed originals of any other form prescribed by applicable Law 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 Borrowers or the Administrative Agent to determine the withholding or deduction required to be made; and (D) if a payment made to a Recipient under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Recipient 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 Recipient shall deliver to the Borrowers and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrowers 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 Borrowers or the Administrative Agent as may be necessary for the Borrowers and the Administrative Agent to comply with their obligations under FATCA and to determine that such Recipient has complied with such Recipient’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 Recipient 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 Borrowers and the Administrative Agent in writing of its legal inability to do so. 5.9.8. 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 5.9 [Taxes] (including by the payment of additional amounts pursuant to this Section 5.9 [Taxes]), 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 5.9 [Taxes] 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 Official Body with respect to such refund). Such indemnifying party, upon the request of such indemnified party incurred in connection with obtaining such refund, shall repay to such indemnified party the amount paid over pursuant to this Section 5.9.8 [Treatment of Certain Refunds] (plus any penalties, interest or other charges imposed by the relevant Official Body) in the event that such indemnified party is required to repay such refund to such Official Body. Notwithstanding anything to the contrary in this Section 5.9.8 [Treatment of Certain Refunds]), in no event will the indemnified party be required to pay any amount to an {N0289348 2 } 66

indemnifying party pursuant to this Section 5.9.8 [Treatment of Certain Refunds] 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. 5.9.9. Survival. Each party’s obligations under this Section 5.9 [Taxes] shall survive the resignation 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. 5.10 Indemnity. In addition to the compensation or payments required by Section 5.8 [Increased Costs] or Section 5.9 [Taxes], the Borrowers shall indemnify each Lender against all liabilities, losses or expenses (including loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract, but, for the avoidance of doubt, excluding Taxes) which such Lender sustains or incurs as a consequence of any: (i) payment, prepayment, conversion or renewal of any Loan to which a LIBOR Rate Option applies on a day other than the last day of the corresponding Interest Period (whether or not such payment or prepayment is mandatory, voluntary or automatic and whether or not such payment or prepayment is then due), or (ii) attempt by the Borrowers to revoke (expressly, by later inconsistent notices or otherwise) in whole or part any Loan Requests under Section 2.5 [Revolving Credit Loan Requests; Swing Loan Requests] or Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.6 [Voluntary Prepayments]. If any Lender sustains or incurs any such loss or expense, it shall from time to time notify the Borrowers of the amount determined in good faith by such Lender (which determination may include such assumptions, allocations of costs and expenses and averaging or attribution methods as such Lender shall deem reasonable) to be necessary to indemnify such Lender for such loss or expense. Such notice shall set forth in reasonable detail the basis for such determination. Such amount shall be due and payable by the Borrowers to such Lender ten (10) Business Days after such notice is given. 5.11 Settlement Date Procedures. In order to minimize the transfer of funds between the Lenders and the Administrative Agent, the Borrowers may borrow, repay and reborrow Swing Loans and FNB may make Swing Loans as provided in Section 2.1.2 [Swing Loan Commitment] hereof during the period between Settlement Dates. The Administrative Agent shall notify each Lender of its Ratable Share of the total of the Revolving Credit Loans and the Swing Loans (each a “Required Share”). On such Settlement Date, each Lender shall pay to the Administrative Agent the amount equal to the difference between its Required Share and its {N0289348 2 } 67

Revolving Credit Loans, and the Administrative Agent shall pay to each Lender its Ratable Share of all payments made by the Borrowers to the Administrative Agent with respect to the Revolving Credit Loans. The Administrative Agent shall also effect settlement in accordance with the foregoing sentence on the proposed Borrowing Dates for Revolving Credit Loans and on any mandatory prepayment date as provided for herein and may at its option effect settlement on any other Business Day. These settlement procedures are established solely as a matter of administrative convenience, and nothing contained in this Section 5.11 shall relieve the Lenders of their obligations to fund Revolving Credit Loans on dates other than a Settlement Date pursuant to Section 2.1.2 [Swing Loan Commitment]. The Administrative Agent may at any time at its option for any reason whatsoever require each Lender to pay immediately to the Administrative Agent such Lender’s Ratable Share of the outstanding Revolving Credit Loans and each Lender may at any time require the Administrative Agent to pay immediately to such Lender its Ratable Share of all payments made by the Borrowers to the Administrative Agent with respect to the Revolving Credit Loans. 5.12 Receipt and Application of Payments. On the earliest date reasonable practicable, and in no event more that fifteen (15) days following the Closing Date (such date, the “Transition Date”), each Loan Party shall establish and maintain a depository account with the Administrative Agent, subject to the provisions of this Section 5.12 [Receipt and Application of Payments], such other provisions as the Administrative Agent may require and such other related agreements as the Administrative Agent may require (the “Cash Collateral Account”). From and after the occurrence of an Event of Default, each Loan Party, upon request by the Administrative Agent, shall promptly establish with the Administrative Agent and maintain a lockbox account (“Lockbox”) subject to the provisions of this Section 5.12 [Receipt and Application of Payments], such other provisions as the Administrative Agent may require, and such other related agreements as the Administrative Agent may require. For all contracts awarded to any Loan Party after the Transition Date, including new contracts awarded by current Account Debtors, all individual task orders and delivery orders awarded to any Loan Party after the Transition Date on contracts in existence on the Transition Date, and all option period extensions of contracts in existence on the Transition Date (each a “New Contract”), such Loan Party shall notify and direct such Account Debtors to remit payments directly to Cash Collateral Account or the Lockbox, as the case may be. Any funds collected in the Lockbox (if any) shall be transferred to the Cash Collateral Account. Each Loan Party shall designate the Cash Collateral Account in the federal System for Award Management (formerly the Central Contractor Registration) as the account to receive payments due from the Government with respect to New Contracts. Following the Transition Date, each Loan Party will cooperate with the Administrative Agent on an orderly basis and use commercially reasonable efforts such that as soon as reasonably practicable after the Transition Date, but in no event later than one hundred eighty (180) days after the Closing Date, all contracts in existence on the Transition Date shall be subject to the requirements set forth herein applicable to New Contracts, and after the date a contract in existence on the Transition Date becomes subject to the requirements applicable to New Contracts, it shall thereafter constitute a New Contract. In the event any Loan Party (or any of its Affiliates, shareholders, directors, officers, employees, Administrative Agents or those Person acting for or in concert with any other Loan Party) shall receive any cash, checks, notes, drafts or other similar items of payment relating to or constituting the Collateral (or proceeds thereof), no later than the first Business Day following receipt thereof, such Loan Party shall (i) deposit or cause the same to be deposited, in kind, in the Cash Collateral Account {N0289348 2 } 68

or the Lockbox, as applicable, or such other depository as may be designated in writing by the Administrative Agent (the “Depository”), from which account the Administrative Agent alone shall have sole power of withdrawal, and with respect to which the Depository shall waive any rights of set off, and (ii) forward to the Administrative Agent on a daily basis, a collection report in form and substance satisfactory to the Administrative Agent and, at the Administrative Agent’s request, copies of all such items and deposit slips related thereto. All cash, notes, checks, drafts or similar items of payment by or for the account of any Loan Party shall be the sole and exclusive property of the Lenders immediately upon the earlier of the receipt of such items by the Administrative Agent or the Depository or the receipt of such items by any Loan Party; provided, however, that for the purpose of computing interest hereunder such items shall be deemed to have been collected and shall be applied by the Administrative Agent on account of the Revolving Credit Loans one (1) Business Day after receipt by the Administrative Agent (subject to correction for any items subsequently dishonored for any reason whatsoever). Notwithstanding anything to the contrary herein, all such items of payment shall, solely for purposes of determining the occurrence of an Event of Default, be deemed received upon actual receipt by the Administrative Agent, unless the same are subsequently dishonored for any reason whatsoever.

The liability of the Borrowers for all of the Obligations shall be joint and several regardless of which Borrower actually receives Loans or other extensions of credit hereunder or the amount of such Loans received or the manner in which the Administrative Agent and the Lenders account for such Loans or other extensions of credit on their respective books and records. Each Borrower acknowledges that its Obligations arising as a result of joint and several liability shall, to the full extent permitted by law, be unconditional and shall constitute primary obligations of such Borrower. 6. REPRESENTATIONS AND WARRANTIES 6.1 Representations and Warranties. The Loan Parties, jointly and severally, represent and warrant to the Administrative Agent and each of the Lenders as follows: {N0289348 2 } 69

No Conflict; Material Agreements. Neither the execution and delivery of this Agreement or the other Loan Documents or the Acquisition Documents by any Loan Party nor the consummation of the transactions herein or therein contemplated or compliance with the terms and provisions hereof or thereof by any of them will conflict with, constitute a default under or result in any breach of (i) the terms and conditions of the certificate of incorporation, bylaws, certificate of limited partnership, partnership agreement, certificate of formation, limited liability company agreement or other organizational documents of any Loan Party or (ii) except as set forth on Schedule 6.1.4 hereto, any Law or any material agreement or instrument or order, writ, judgment, injunction or decree to which any Loan Party or any of its Subsidiaries is a party or by which it or any of its Subsidiaries is bound or to which it is subject, or result in the creation or enforcement of any Lien, charge or encumbrance whatsoever upon any property (now or hereafter acquired) of any Loan Party or any of its Subsidiaries (other than Liens granted under the Loan Documents), except, in each case, any breach that would not be reasonably be expected to result in a Material Adverse Change. There is no default under such material agreement (referred to above) and none of the Loan Parties or their Subsidiaries is bound by any contractual obligation, or subject to any restriction in any organization document, or any requirement of Law which could result in a Material Adverse Change. 6.1.5.

The Loan Parties acknowledge that the Lenders will be irreparably harmed if any Loan Party fails or refuses to execute and deliver to the Administrative Agent any Government Contract Assignment as and when required pursuant to this Section 8.1.8, and that the Lenders have no adequate remedy at law. In such event, the Loan Parties agree that the Administrative Agent shall be entitled, in addition to all other rights and remedies available to the Administrative Agent and the Lenders, to injunctive or other equitable relief to compel the Loan Parties’ full compliance with the requirements of this Section 8.1.8.

Each of the Lenders and the Issuing Lender hereby irrevocably appoints FNB to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents 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 or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Section 10 are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Lender, and neither the Borrowers nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions. 10.2 Rights as a Lender. 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 the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrowers or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders. 10.3 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent: (a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Potential Default or Event of Default has occurred and is continuing; (b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable Law; and {N0289348 2 } 97

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrowers or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent 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 shall be necessary, under the circumstances as provided in Sections 12.1 [Modifications, Amendments or Waivers] and 9.2 [Consequences of Event of Default]) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Potential Default or Event of Default unless and until notice describing such Potential Default or Event of Default is given to the Administrative Agent by the Borrowers, a Lender or the Issuing Lender. The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Potential Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 7 [Conditions of Lending and Issuance of Letters of Credit] or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 10.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Lender unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Lender prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 10.5 Delegation of Duties. The Administrative Agent may perform any and all 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 {N0289348 2 } 98

Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section 10 shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 10.6 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Lender and the Borrowers. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, with approval from the Borrowers (so long as no Event of Default has occurred and is continuing), to appoint a successor, such approval not to be unreasonably withheld or delayed. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) calendar days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the Issuing Lender, appoint a successor Administrative Agent; provided that if the Administrative Agent shall notify the Borrowers and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the Issuing Lender under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (ii) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the Issuing Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section 10.6. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section 10.6 [Resignation of Administrative Agent]). The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Section 10 [The Administrative Agent] and Section 12.3 [Expenses; Indemnity; Damage Waiver] 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. If FNB resigns as Administrative Agent under this Section 10.6, FNB shall also resign as an Issuing Lender. Upon the appointment of a successor Administrative Agent hereunder, such successor shall (i) succeed to all of the rights, powers, privileges and duties of FNB as the retiring Issuing Lender and Administrative Agent and FNB shall be discharged from all of its respective duties and obligations as Issuing Lender and Administrative Agent under the Loan Documents, and (ii) issue letters of credit in substitution for the Letters of Credit issued by FNB, {N0289348 2 } 99

if any, outstanding at the time of such succession or make other arrangement satisfactory to FNB to effectively assume the obligations of FNB with respect to such Letters of Credit. 10.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the Issuing Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. 10.8 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Administrative Agent or Lenders listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the Issuing Lender hereunder. 10.9 Fees.

This Section 12.3.2 [Indemnification by the Borrower] shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim. 12.3.3.

Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions: (i) Minimum Amounts. (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the 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 (B) in any case not described in clause (i)(A) of this Section 12.8.2, the aggregate amount of the Commitment (which for this purpose includes Loans {N0289348 2 } 109

outstanding thereunder) or, if the applicable Commitment is not then in effect, 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 Agreement with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption Agreement, as of the Trade Date) shall not be less than $5,000,000, in the aggregate taking into account any assignment in respect of the Revolving Credit Commitment of the assigning Lender and the Term Loan of the assigning Lender, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrowers otherwise consent (each such consent not to be unreasonably withheld or delayed). (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. No consent shall be required for any assignment except for the consent of the Administrative Agent (which shall not be unreasonably withheld or delayed) and: (A) the consent of the Borrowers (such consent not to be unreasonably withheld or delayed) 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 Borrowers shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; and (B) the consent of the Issuing Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding).

The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption Agreement, together with a processing and recordation fee of $3,500, and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an administrative questionnaire provided by the Administrative Agent. (v) 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 Section 12.8.3 [Register], from and after the effective date specified in each Assignment and Assumption Agreement, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption Agreement, 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 Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption Agreement covering all of the assigning Lender’s rights and obligations under this Agreement, {N0289348 2 } 110

such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 4.4 [LIBOR Rate Unascertainable; Etc.], 5.8 [Increased Costs], and 12.3 [Expenses, Indemnity; Damage Waiver] 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 Section 12.8.2 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 Section 12.8.4 [Participations]. 12.8.3. Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain a record of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time. Such register shall be conclusive, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is in such register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. Such 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. 12.8.4. Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrowers or any of the Borrowers’ Affiliates or Subsidiaries) (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 its Commitment and/or 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 and (iii) the Borrowers, the Administrative Agent, the Lenders, and the Issuing Lender shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree (other than as is already provided for herein) to any amendment, modification or waiver with respect to Sections 12.1.1 [Increase of Commitment], 12.1.2 [Extension of Payment, Etc.], or 12.1.3 [Release of Collateral or Guarantor]) that affects such Participant. The Borrowers agree that each Participant shall be entitled to the benefits of Sections 4.4 [LIBOR Rate Unascertainable, Etc.], 5.8 [Increased Costs], 5.10 [Indemnity] and 5.9 [Taxes] (subject to the requirements and limitations therein, including the requirements under Section 5.9.7 [Status of Lenders] (it being understood that the documentation required under Section 5.9.7 [Status of Lenders] shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.8.2 [Assignments by Lenders]; provided that such Participant (A) agrees to be subject to the provisions of Section 5.6.2 [Replacement of a Lender] and Section 5.6.3 [Designation of a Different Lending Office] as if it were an assignee under Section 12.8.2 [Assignments by Lenders]; and (B) shall not be entitled to receive any greater payment under Sections 5.8 [Increased Costs] or 5.9 [Taxes], with respect to any participation, than its participating Lender {N0289348 2 } 111

would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrowers’ request and expense, to use reasonable efforts to cooperate with the Borrowers to effectuate the provisions of Section 5.6.2 [Replacement of a Lender] and Section 5.6.3 [Designation of a Different Lending Office] with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.2.3 [Set-off] as though it were a Lender; provided that such Participant agrees to be subject to Section 5.3 [Sharing of Payments by Lenders] as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrowers, 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 commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit 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. 12.8.5. Certain Pledges; Successors and Assigns Generally. 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. 12.9 Confidentiality. 12.9.1. General. Each of the Administrative Agent, the Lenders and the Issuing Lender agrees to maintain the confidentiality of the Information, except that Information may be disclosed (i) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable Laws or regulations or by any subpoena or similar legal process, (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or {N0289348 2 } 112

obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrowers and their Obligations, (vii) with the consent of the Borrowers or (viii) to the extent such Information (Y) becomes publicly available other than as a result of a breach of this Section or (Z) becomes available to the Administrative Agent, any Lender, the Issuing Lender or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrowers or the other Loan Parties. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 12.9.2. Sharing Information with Affiliates of the Lenders. Each Loan Party acknowledges that from time to time financial advisory, investment banking and other services may be offered or provided to the Borrowers or one or more of their Affiliates (in connection with this Agreement or otherwise) by any Lender or by one or more Subsidiaries or Affiliates of such Lender and each of the Loan Parties hereby authorizes each Lender to share any information delivered to such Lender by such Loan Party and its Subsidiaries pursuant to this Agreement to any such Subsidiary or Affiliate subject to the provisions of Section 12.9.1 [General]. 12.10 Counterparts; Integration; Effectiveness. 12.10.1. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and 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 including any prior confidentiality agreements and commitments. Except as provided in Section 7 [Conditions Of Lending And Issuance Of Letters Of Credit], 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 that, when taken together, bear the signatures of each of the other parties hereto.

To induce the Agent, the Lenders and any Affiliate of any of the foregoing that provides any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Services Product (collectively, together with any provider of any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Services Product, the “Secured Parties” and each a “Secured Party”) to make loans and grant other financial accommodations to the Borrowers under the Credit Agreement, the other Loan Documents, any Lender Provided Interest Rate Hedge and any Other Lender Provided Financial Service Products (collectively, the “Secured Loan Documents” and each a “Secured Loan Document”), each Guarantor hereby jointly and severally, unconditionally, and irrevocably reconfirms its guaranty under the Existing Guaranty Agreement, if any, and guaranties anew to the Secured Parties, and confirms its status as surety or becomes surety, as applicable, as though it was a primary obligor for, the full and punctual payment and performance when due (whether on demand, at stated maturity, by acceleration, or otherwise and including any amounts which would become due but for the operation of an automatic stay under the federal bankruptcy code of the United States or any similar Laws of any country or jurisdiction) of all Obligations, now existing or hereafter arising (and including obligations, liabilities, and indebtedness arising or accruing after the commencement of any bankruptcy, insolvency, reorganization, or similar proceeding with respect to any Borrower or any Guarantor or which would have arisen or accrued but for the commencement of such proceeding, even if the claim for such obligation, liability, or indebtedness is not enforceable or allowable in such proceeding, and including all Obligations, liabilities, and indebtedness arising from any extensions of credit under or in connection with the Secured Loan Documents from time to time, regardless whether any such extensions of credit are in excess of the amount committed under or contemplated by the Secured Loan Documents or are made in circumstances in which any condition to extension of credit is not satisfied) (herein collectively as the “Guarantied Obligations” and each as a “Guarantied Obligation”). Without limitation of the foregoing, any of the Guarantied Obligations shall be and remain Guarantied Obligations entitled to the benefit of this Guaranty if the Agent or any of the Lenders (or any one or more assignees or transferees thereof) from time to time assign or otherwise transfer all or any portion of their respective rights and obligations under the Secured Loan Documents, or any other Guaranteed Obligations, in each case, to the extent permitted by the applicable Secured Loan Documents. In furtherance of the foregoing, each Guarantor jointly and severally agrees as follows: 2. Guaranty. Each Guarantor hereby promises to pay and perform all such Guarantied Obligations promptly upon demand of the Agent and the Secured Parties or any one or more of them. All payments made hereunder shall be made by each Guarantor in immediately available funds in U.S. Dollars and shall be made without setoff, counterclaim, withholding, or other deduction of any nature (except as expressly permitted by Section 5.9 [Taxes] of the Credit Agreement). 3. Obligations Absolute. To the fullest extent permitted by law and except for termination or release of a Guarantor’s obligations hereunder in accordance with the terms of Section 19, the obligations of the Guarantors hereunder shall not be discharged or impaired or otherwise diminished by the failure, default, omission, or delay, willful or otherwise, by any Lender, the Agent, or any Borrower or any other obligor on any of the Guarantied Obligations, {N0289348 2 } - 3 - 49920573

or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity. To the fullest extent permitted by law and except for termination or release of a Guarantor’s obligations hereunder in accordance with the terms of Section 19, without limiting the generality of the foregoing, each Guarantor hereby waives any defense based on or arising out of, and agrees that the joint and several obligations of each Guarantor hereunder shall not be diminished, terminated, or otherwise similarly affected by, any of the following or any failure of any Guarantor to consent thereto: (a) Any lack of genuineness, legality, validity, enforceability or allowability (in a bankruptcy, insolvency, reorganization or similar proceeding, or otherwise), or any avoidance or subordination, in whole or in part, of any Secured Loan Document or any of the Guarantied Obligations and regardless of any Law, regulation or order now or hereafter in effect in any jurisdiction affecting any of the Guarantied Obligations, any of the terms of the Secured Loan Documents, or any rights of the Agent or the Secured Parties or any other Person with respect thereto; (b) Any increase, decrease, or change in the amount, nature, type or purpose of any of, or any release, surrender, exchange, compromise or settlement of any of the Guarantied Obligations (whether or not contemplated by the Secured Loan Documents as presently constituted); any change in the time, manner, method, or place of payment or performance of, or in any other term of, any of the Guarantied Obligations; any execution or delivery of any additional Secured Loan Documents; or any amendment, modification or supplement to, or refinancing or refunding of, any Secured Loan Document or any of the Guarantied Obligations; (c) Any failure to assert any breach of or default under any Secured Loan Document or any of the Guarantied Obligations; any extensions of credit in excess of the amount committed under or contemplated by the Secured Loan Documents, or in circumstances in which any condition to such extensions of credit has not been satisfied; any other exercise or non-exercise, or any other failure, omission, breach, default, delay, or wrongful action in connection with any exercise or non-exercise, of any right or remedy against any Borrower or any other Person under or in connection with any Secured Loan Document or any of the Guarantied Obligations; any refusal of payment or performance of any of the Guarantied Obligations, whether or not with any reservation of rights against any Guarantor; or any application of collections (including but not limited to collections resulting from realization upon any direct or indirect security for the Guarantied Obligations) to other obligations, if any, not entitled to the benefits of this Guaranty, in preference to Guarantied Obligations entitled to the benefits of this Guaranty, or if any collections are applied to Guarantied Obligations, any application to particular Guarantied Obligations; (d) Any taking, exchange, amendment, modification, waiver, supplement, termination, subordination, compromise, release, surrender, loss, or impairment of, or any failure to protect, perfect, or preserve the value of, or any enforcement of, realization upon, or exercise of rights, or remedies under or in connection with, or any failure, omission, breach, default, delay, or wrongful action by the Agent or the Secured Parties, or any of them, or any other Person in connection with the enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or, any other action or inaction by any of the Agent or the {N0289348 2 } - 4 - 49920573

Secured Parties, or any of them, or any other Person in respect of, any direct or indirect security for any of the Guarantied Obligations. As used in this Guaranty, “direct or indirect security” for the Guarantied Obligations, and similar phrases, includes any collateral security, guaranty, suretyship, letter of credit, capital maintenance agreement, put option, subordination agreement, or other right or arrangement of any nature providing direct or indirect assurance of payment or performance of any of the Guarantied Obligations, made by or on behalf of any Person; (e) Except as expressly permitted in the Credit Agreement, any merger, consolidation, liquidation, dissolution, winding-up, charter revocation, or forfeiture, or other change in, restructuring or termination of the corporate structure or existence of, any Borrower or any other Person; any bankruptcy, insolvency, reorganization or similar proceeding with respect to any Borrower or any other Person; or any action taken or election made by the Agent or the Secured Parties, or any of them (including but not limited to any election under Section 1111(b)(2) of the United States Bankruptcy Code), any Borrower, or any other Person in connection with any such proceeding; (f) Any defense, setoff, or counterclaim which may at any time be available to or be asserted by any Borrower or any other Person with respect to any Secured Loan Document or any of the Guarantied Obligations; or any discharge by operation of Law or release of any Borrower or any other Person from the performance or observance of any Secured Loan Document or any of the Guarantied Obligations, except in each case Payment in Full of the Guaranteed Obligations; and (g) Any other event or circumstance, whether similar or dissimilar to the foregoing, and whether known or unknown, which might otherwise constitute a defense available to, or limit the liability of, any Guarantor, a guarantor or a surety, excepting Payment in Full of the Guarantied Obligations. Each Guarantor acknowledges, consents, and agrees that new Guarantors may join in this Guaranty pursuant to Section 8.1.14 [Additional Collateral] of the Credit Agreement and each Guarantor affirms that its obligations shall continue hereunder undiminished. 4. Waivers, etc. Without limitation and to the fullest extent permitted by applicable Law and except for termination or release of a Guarantor’s obligations hereunder in accordance with the terms of Section 19, each Guarantor waives each of the following: (a) All notices, disclosures and demands of any nature which otherwise might be required from time to time to preserve intact any rights against any Guarantor, including the following: any notice of any event or circumstance described in Section 3 hereof; any notice required by any Law, regulation or order now or hereafter in effect in any jurisdiction; any notice of nonpayment, nonperformance, dishonor, or protest under any Secured Loan Document or any of the Guarantied Obligations; any notice of the incurrence of any Guarantied Obligation; any notice of any default or any failure on the part of any Borrower or any other Person to comply with any Secured Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; and any notice of any information pertaining to the business, operations, condition (financial or otherwise) or prospects of any Borrower or any other Person; {N0289348 2 } - 5 - 49920573

(b) Any right to any marshalling of assets, to the filing of any claim against any Borrower or any other Person in the event of any bankruptcy, insolvency, reorganization or similar proceeding, or to the exercise against any Borrower or any other Person of any other right or remedy under or in connection with any Secured Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; any requirement of promptness or diligence on the part of the Agent or the Secured Parties, or any of them, or any other Person; any requirement to exhaust any remedies under or in connection with, or to mitigate the damages resulting from default under, any Secured Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; any benefit of any statute of limitations; and any requirement of acceptance of this Guaranty or any other Secured Loan Document, and any requirement that any Guarantor receive notice of any such acceptance; (c) Any defense or other right arising by reason of any Law now or hereafter in effect in any jurisdiction pertaining to election of remedies (including anti-deficiency Laws, “one action” Laws or the like), or by reason of any election of remedies or other action or inaction by the Agent or the Secured Parties, or any of them (including but not limited to commencement or completion of any judicial proceeding or nonjudicial sale or other action in respect of collateral security for any of the Guarantied Obligations), which results in denial or impairment of the right of the Agent or the Secured Parties, or any of them, to seek a deficiency against any Borrower or any other Person or which otherwise discharges or impairs any of the Guarantied Obligations; and (d) Any and all defenses it may now or hereafter have based on principles of suretyship, impairment of collateral, or the like. 5. Reinstatement. Notwithstanding anything to the contrary contained in this Guaranty, this Guaranty shall continue to be effective or be reinstated, as the case may be, any time any payment of any of the Guarantied Obligations is rescinded, recouped, avoided, or must otherwise be returned or released by any Secured Party or Agent upon or during the insolvency, bankruptcy, or reorganization of, or any similar proceeding affecting, any Borrower or for any other reason whatsoever, all as though such payment had not been made and was due and owing. 6. Subrogation. Each Guarantor agrees it will not exercise any rights against any Borrower or any other Guarantor arising in connection with, or any Collateral securing, the Guarantied Obligations (including rights of subrogation, contribution, and the like) until the Guarantied Obligations have been Paid in Full. If any amount shall be paid to any Guarantor by or on behalf of any Borrower or any other Guarantor by virtue of any right of subrogation, contribution, or the like, such amount shall be deemed to have been paid to such Guarantor for the benefit of, and shall be held in trust for the benefit of, the Agent and the Secured Parties and shall forthwith be paid to the Agent to be credited and applied upon the Guarantied Obligations, whether matured or unmatured, in accordance with the terms of the applicable Secured Loan Documents. 7. No Stay. Without limitation of any other provision of this Guaranty, if any declaration of default or acceleration or other exercise or condition to exercise of rights or {N0289348 2 } - 6 - 49920573

remedies under or with respect to any Guarantied Obligation shall at any time be stayed, enjoined, or prevented for any reason (including any stay or injunction resulting from the pendency against any Borrower or any other Person of a bankruptcy, insolvency, reorganization or similar proceeding), the Guarantors agree that, for the purposes of this Guaranty and their obligations hereunder, the Guarantied Obligations shall be deemed to have been declared in default or accelerated, and such other exercise or conditions to exercise shall be deemed to have been taken or met. 8. Taxes. The terms of Section 5.9 of the Credit Agreement are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 9. Notices. Each Guarantor agrees that all notices, statements, requests, demands and other communications under this Guaranty shall be given to such Guarantor at the address set forth on a Schedule to, or in a Guarantor Joinder given under, the Credit Agreement and in the manner provided in Section 12.5 [Notices; Effectiveness; Electronic Communication] of the Credit Agreement. The Agent and the Lenders may rely on any notice (whether or not made in a manner contemplated by this Guaranty) purportedly made by or on behalf of a Guarantor, and the Agent and the Lenders shall have no duty to verify the identity or authority of the Person giving such notice. 10. Counterparts; Telecopy Signatures. This Guaranty may be executed in any number of counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument. Each Guarantor acknowledges and agrees that a telecopy transmission to Agent or any Lender of, or the e-mail delivery of a portable document format (PDF) file to the Agent or any Lender containing, the signature pages hereof purporting to be signed on behalf of any Guarantor shall constitute effective and binding execution and delivery hereof by such Guarantor. 11. Default Payments by Borrowers. (a) In the event that at any time any Guaranteed Obligation now or hereafter existing under this Guaranty shall have become due and payable, the Agent and the Lenders, or any of them shall have all rights and remedies available pursuant to the Credit Agreement. (b) Upon the occurrence and during the continuation of any default under any Guarantied Obligation, if any amount shall be paid to any Guarantor by or for the account of any Borrower, such amount shall be held in trust for the benefit of each Lender and Agent and shall forthwith be paid to the Agent to be credited and applied to the Guarantied Obligations when due and payable. 12. Construction. This Guaranty has been fully negotiated between the applicable parties, each party having the benefit of legal counsel, and accordingly neither any doctrine of construction of guaranties or suretyships in favor of the guarantor or surety, nor any doctrine of construction of ambiguities in agreement or instruments against the party controlling the drafting thereof, shall apply to this Guaranty. 13. Successors and Assigns. This Guaranty shall be binding upon each Guarantor, its successors and assigns, and shall inure to the benefit of and be enforceable by the Agent and the {N0289348 2 } - 7 - 49920573

Secured Parties, or any of them, and their successors and assigns as permitted under the Credit Agreement provided, however, that, without the consent of the Agent, no Guarantor may assign or transfer any of its rights or obligations hereunder or any interest herein and any such purported assignment or transfer shall be null and void. Without limitation of the foregoing, the Agent and the Secured Parties, or any of them (and any successive assignee or transferee), from time to time may assign or otherwise transfer all or any portion of its rights or obligations under and in accordance with the Secured Loan Documents (including all or any portion of any commitment to extend credit), or any other Guarantied Obligations, to any other person and such Guarantied Obligations (including any Guarantied Obligations resulting from extension of credit by such other Person under or in connection with the Secured Loan Documents) shall be and remain Guarantied Obligations entitled to the benefit of this Guaranty, and to the extent of its interest in such Guarantied Obligations such other Person shall be vested with all the benefits in respect thereof granted to the Agent and the Secured Parties in this Guaranty or otherwise. 14. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. The terms of Sections 12.11.1, 12.11.2, 12.11.3, 12.11.4 and 12.11.5 of the Credit Agreement with respect to governing law, submission to jurisdiction, venue, consent to service of process and waiver of jury trial are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 15. Severability; Modification to Conform to Law. (a) It is the intention of the parties that this Guaranty be enforceable to the fullest extent permissible under applicable Law, but that the unenforceability (or modification to conform to such Law) of any provision or provisions hereof shall not render unenforceable, or impair, the remainder hereof. If any provision in this Guaranty shall be held invalid or unenforceable in whole or in part in any jurisdiction, this Guaranty shall, as to such jurisdiction, be deemed amended to modify or delete, as necessary, the offending provision or provisions and to alter the bounds thereof in order to render it or them valid and enforceable to the maximum extent permitted by applicable Law, without in any manner affecting the validity or enforceability of such provision or provisions in any other jurisdiction or the remaining provisions hereof in any jurisdiction. (b) Without limitation of the preceding subsection (a), to the extent that applicable Law (including applicable Laws pertaining to fraudulent conveyance or fraudulent or preferential transfer) otherwise would render the full amount of the Guarantor’s obligations hereunder invalid, voidable, or unenforceable on account of the amount of a Guarantor’s aggregate liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the aggregate amount of such liability shall, without any further action by the Agent or any of the Secured Parties or such Guarantor or any other Person, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding, which (without limiting the generality of the foregoing) may be an amount which is equal to the greater of: (i) the fair consideration actually received by such Guarantor under the terms and as a result of the Secured Loan Documents and the value of the benefits described in Section 18(b) hereof, including (and to the extent not inconsistent with applicable federal and {N0289348 2 } - 8 - 49920573

state Laws affecting the enforceability of guaranties) distributions, commitments, and advances made to or for the benefit of such Guarantor with the proceeds of any credit extended under the Secured Loan Documents, or (ii) the excess of (1) the amount of the fair value of the assets of such Guarantor as of the date of this Guaranty as determined in accordance with applicable federal and state Laws governing determinations of the insolvency of debtors as in effect on the date hereof, over (2) the amount of all liabilities of such Guarantor as of the date of this Guaranty, also as determined on the basis of applicable federal and state Laws governing the insolvency of debtors as in effect on the date hereof. (c) Notwithstanding anything to the contrary in this Section or elsewhere in this Guaranty, this Guaranty shall be presumptively valid and enforceable to its full extent in accordance with its terms, as if this Section (and references elsewhere in this Guaranty to enforceability to the fullest extent permitted by Law) were not a part of this Guaranty, and in any related litigation the burden of proof shall be on the party asserting the invalidity or unenforceability of any provision hereof or asserting any limitation on any Guarantor’s obligations hereunder as to each element of such assertion. 16. Additional Guarantors. At any time after the initial execution and delivery of this Guaranty to the Agent, additional Persons may become parties to this Guaranty and thereby acquire the duties and rights of being Guarantors hereunder by executing and delivering to the Agent a Guarantor Joinder pursuant to the Credit Agreement. No notice of the addition of any Guarantor shall be required to be given to any pre-existing Guarantor and each Guarantor hereby consents thereto. 17. Joint and Several Obligations. The obligations and additional liabilities of the Guarantors under this Agreement are joint and several obligations of the Guarantors, and each Guarantor hereby waives to the full extent permitted by Law any defense it may otherwise have to the payment and performance of the Obligations that its liability hereunder is limited and not joint and several. Each Guarantor acknowledges and agrees that the foregoing waivers and those set forth below serve as a material inducement to the agreement of the Agent and the Secured Parties to make the Loans, and that the Agent and the Secured Parties are relying on each specific waiver and all such waivers in entering into this Guaranty. The undertakings of each Guarantor hereunder secure the obligations of itself and the other Guarantors. The Agent and the Secured Parties, or any of them, may, in their sole discretion, elect to enforce this Guaranty against any Guarantor without any duty or responsibility to pursue any other Guarantor and such an election by the Agent and the Secured Parties, or any of them, shall not be a defense to any action the Agent and the Secured Parties, or any of them, may elect to take against any Guarantor. Each of the Secured Parties and Agent hereby reserve all rights against each Guarantor. 18. Miscellaneous. (a) Amendments, Waivers. No amendment to or waiver of any provision of this Guaranty, and no consent to any departure by any Guarantor herefrom, shall in any event be effective unless in a writing signed by the Agent, on behalf of the Lenders, and (i) for any such {N0289348 2 } - 9 - 49920573

amendment, the Borrowers and the Guarantors, and (ii) for any such waiver, the Borrowers on behalf of the Guarantors. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No delay or failure of the Agent or the Lenders, or any of them, in exercising any right or remedy under this Guaranty shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies of the Agent and the Secured Parties under this Guaranty are cumulative and not exclusive of any other rights or remedies available hereunder, under any other agreement or instrument, by Law, or otherwise. (b) Telecommunications. Each Lender and Agent shall be entitled to rely on the authority of any individual making any telecopy or telephonic notice, request, or signature without the necessity of receipt of any verification thereof. (c) Expenses. Each Guarantor unconditionally agrees that the Agent and the Lenders shall be entitled to reimbursement of their expenses incurred hereunder as provided in Section 12.3.1 [Costs and Expenses] of the Credit Agreement. (d) Prior Understandings. This Guaranty and the other Secured Loan Documents constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersede any and all other prior and contemporaneous understandings and agreements. (e) Survival. All representations and warranties of the Guarantors made in connection with this Guaranty shall survive, and shall not be waived by, the execution and delivery of this Guaranty, any investigation by or knowledge of the Agent and the Secured Parties, or any of them, any extension of credit, or any other event or circumstance whatsoever. (f) No Novation. The provisions of Section 12.13(a) of the Credit Agreement regarding novation are hereby incorporated herein by reference and shall apply mutatis mutandis with respect to the other provisions of this Guaranty. 19. Termination (a) This Guaranty is a continuing obligation of the Guarantors and shall remain in full force and effect notwithstanding that no Guarantied Obligations may be outstanding from time to time and notwithstanding any other event or circumstance. Upon Payment in Full of all Guarantied Obligations, this Guaranty shall terminate, subject to Section 5 hereof. (b) In connection with any termination or release pursuant to paragraph (a) above, the Agent shall promptly execute and deliver to any Guarantor, upon such Guarantor’s reasonable request and at such Guarantor’s expense, evidence of such termination. Any execution and delivery of such evidence pursuant to this Section 19 shall be without recourse to or warranty by the Agent. (c) At any time that the Borrowers desire that the Agent take any of the actions described in the immediately preceding clause (b), they shall, upon request of the Agent, deliver to the Agent an officer’s certificate certifying that the release of the respective Guarantor is permitted pursuant to paragraph (a) above. The Agent shall have no liability whatsoever to any {N0289348 2 } - 10 - 49920573

Secured Party as a result of any release of any Guarantor by it as permitted (or which the Agent in good faith believes to be permitted) by this Section 19. [SIGNATURE PAGES FOLLOW] {N0289348 2 } - 11 - 49920573

IN WITNESS WHEREOF, each Guarantor intending to be legally bound, has executed this Guaranty as of the date first above written. [_________________] By: Name: Title: {N0289348 2 }

WHEREAS, reference is made to that certain Credit Agreement, dated June 7, 2019, by and among certain of the Pledgors, as borrowers, and the other guarantors party thereto, the lenders party thereto and the Agent (the “Existing Credit Agreement”); WHEREAS, simultaneously with the execution and delivery of the Existing Credit Agreement, Holdings, Solutions, Danya and Systems (collectively, the “Original Pledgors”) and Agent entered into that certain Patent, Trademark and Copyright Security Agreement, dated as of June 7, 2019 the (“Existing Patent, Trademark and Copyright Security Agreement”), whereby certain of the Pledgors agreed, among other things, to grant a security interest to the Agent in certain patents, trademarks, copyrights and other property as security for loans and other obligations as more fully described therein; WHEREAS, pursuant to that certain Amended and Restated Credit Agreement (as amended, restated, modified or supplemented from time to time, the “Credit Agreement”) of even date herewith by and among the Pledgors, the “Lenders” (as defined in the Credit Agreement) and the Agent, the Agent and the Lenders have agreed to amend and restate the Existing Credit Agreement to provide certain loans and to make certain other financial accommodations to the Loan Parties, and WHEREAS, pursuant to and in consideration of the Credit Agreement, the Pledgors have agreed, among other things, to amend and restate the Existing Patent, Trademark and Copyright Security Agreement and reconfirm and grant anew, as applicable, a security interest to the Agent in certain patents, trademarks, copyrights and other property as security for such loans and other obligations as more fully described herein. NOW, THEREFORE, intending to be legally bound hereby, the parties hereto agree as follows: 1. Defined Terms. {N0289348 2 } 6122793

(a) Except as otherwise expressly provided herein, (i) capitalized terms used in this Agreement shall have the respective meanings assigned to them in the Credit Agreement and (ii) the rules of construction set forth in Section 1.2 [Construction] of the Credit Agreement shall apply to this Agreement. Where applicable and except as otherwise expressly provided herein, terms used herein (whether or not capitalized) shall have the respective meanings assigned to them in the Uniform Commercial Code as enacted in Maryland as amended from time to time (the “Code”). (b) “Patents, Trademarks and Copyrights” shall mean and include all of each Pledgor’s present and future right, title and interest in and to the following: all trade names, patent applications, patents, trademark applications, trademarks, service mark applications, service marks, copyright applications and copyrights, whether now owned or hereafter acquired by such Pledgor, including those listed on Schedule A hereto, including all proceeds thereof (such as, by way of example, license royalties and proceeds of infringement suits), the right to sue for past, present and future infringements, all rights corresponding thereto throughout the world and all reissues, divisions, continuations, renewals, extensions and continuations-in-part thereof, and the goodwill of the business to which any of the patents, trademarks and copyrights relate (each of the foregoing, individually, a “Patent, Trademark or Copyright”). (c) “Debt” shall mean all Obligations now existing or hereafter arising. Without limitation of the foregoing, any of the Debt shall be and remain Debt entitled to the benefit of this Agreement if the Agent or any of the Lenders (or any one or more assignees or transferees thereof) from time to time assign or otherwise transfer all or any portion of their respective rights and obligations under the Credit Agreement, the other Loan Documents, any Lender Provided Interest Rate Hedge and any Other Lender Provided Financial Service Products (collectively, the “Secured Loan Documents” and each a “Secured Loan Document”), in each case, to the extent permitted by the applicable Secured Loan Documents. 2. To secure the full payment and performance of all Debt, each Original Pledgor hereby reconfirms its grant under the Existing Patent, Trademark and Copyright Secuirty Agreement and grants anew and IBA grants a security interest to Agent in the entire right, title and interest of such Pledgor in and to all of its Patents, Trademarks and Copyrights. 3. Each Pledgor jointly and severally covenants and warrants that: (a) the Patents, Trademarks and Copyrights are subsisting and have not been adjudged invalid or unenforceable, in whole or in part; (b) to the best of such Pledgor’s knowledge, each of the Patents, Trademarks and Copyrights is valid and enforceable; (c) such Pledgor is the sole and exclusive owner of the entire and unencumbered right, title and interest in and to each of the Patents, Trademarks and Copyrights, free and clear of any liens, charges and encumbrances, including pledges, assignments, licenses, shop rights and covenants by Pledgor not to sue third persons, except for Permitted Liens; {N0289348 2 }

(d) no claim has been made to such Pledgor or, to the knowledge of such Pledgor, any other person that the use of any of the Patents, Trademarks and Copyrights violates the rights of any third party; and (e) such Pledgor has used, and will continue to use for the duration of this Agreement, proper statutory notice in connection with its use of the Patents, Trademarks and Copyrights, except for those Patents, Trademarks and Copyrights that are hereafter allowed to lapse in accordance with Paragraph 12 hereof. 4. Each of the obligations of each Pledgor under this Agreement is joint and several. The Agent and the Lenders, or any of them, may, in their sole discretion, elect to enforce this Agreement against any Pledgor without any duty or responsibility to pursue any other Pledgor and such an election by the Agent and the Lenders, or any of them, shall not be a defense to any action the Agent and the Lenders, or any of them, may elect to take against any Pledgor. Each of the Lenders and Agent hereby reserve all rights against each Pledgor. 5. Each Pledgor agrees that, until all of the Debt shall have been Paid in Full, it will not enter into any agreement (for example, a license agreement) which is inconsistent with any Pledgor’s obligations under this Agreement without Agent’s prior written consent, except leases, subleases, licenses or sublicenses entered into in the ordinary course of business, in each case which do not materially interfere with the business of such Pledgor. 6. If, before the Debt shall have been Paid in Full, any Pledgor shall own any new trademarks or service marks or any new copyrightable or patentable inventions for which Pledgor has decided to pursue a copyright or patent or any registered, issued or applications for patent for any reissue, division, continuation, renewal, extension, or continuation in part of any Patent, Trademark or Copyright or any improvement on any Patent, Trademark or Copyright, the provisions of this Agreement shall automatically apply thereto and such Pledgor shall give to Agent prompt notice thereof in writing. Concurrently with the delivery of each Compliance Certificate delivered pursuant to Section 8.3.4 of the Credit Agreement, each Pledgor and Agent agree to modify this Agreement by amending Schedule A to include any future registered or issued patents, patent applications, trademark applications, registered or issued trademarks, registered or issued copyrights or copyright applications and the provisions of this Agreement shall apply thereto. 7. Agent shall have, in addition to all other rights and remedies given it by this Agreement and those rights and remedies set forth in the Credit Agreement and the other Secured Loan Documents, those allowed by applicable Law and the rights and remedies of a secured party under the Uniform Commercial Code as enacted in any jurisdiction in which the Patents, Trademarks and Copyrights may be located and, without limiting the generality of the foregoing, if an Event of Default has occurred and is continuing, Agent may immediately, without demand of performance and without other notice (except as set forth below) or demand whatsoever to Pledgors, all of which are hereby expressly waived, and without advertisement, sell at public or private sale or otherwise realize upon, in a city that the Agent shall designate by notice to the Pledgors, the whole or from time to time any part of the Patents, Trademarks and Copyrights, or any interest which any Pledgor may have therein and, after deducting from the {N0289348 2 }

proceeds of sale or other disposition of the Patents, Trademarks and Copyrights all expenses (including fees and expenses for brokers and attorneys), shall apply the remainder of such proceeds toward the payment of the Debt as set forth in Section 9.2.4 [Application of Proceeds] of the Credit Agreement. Notice of any sale or other disposition of the Patents, Trademarks and Copyrights shall be given to Pledgors at least ten (10) days before the time of any intended public or private sale or other disposition of the Patents, Trademarks and Copyrights is to be made, which each Pledgor hereby agrees shall be reasonable notice of such sale or other disposition. At any such sale or other disposition, Agent may, to the extent permissible under applicable Law, purchase the whole or any part of the Patents, Trademarks and Copyrights sold, free from any right of redemption on the part of Pledgor, which right is hereby waived and released. 8. If any Event of Default shall have occurred and be continuing, Pledgor hereby authorizes and empowers Agent to make, constitute and appoint any officer or agent of Agent, as Agent may select in its exclusive discretion, as such Pledgor’s true and lawful attorney-in- fact, with the power to endorse such Pledgor’s name on all applications, documents, papers and instruments necessary for Agent to use the Patents, Trademarks and Copyrights, or to grant or issue, on commercially reasonable terms, any exclusive or nonexclusive license under the Patents, Trademarks and Copyrights to any third person, or necessary for Agent to assign, pledge, convey or otherwise transfer title in or dispose of, on commercially reasonable terms, the Patents, Trademarks and Copyrights to any third Person. Each Pledgor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney, being coupled with an interest, shall be irrevocable for the life of this Agreement. 9. (a) Each Pledgor shall promptly execute and deliver to the Agent a Grant of Security Interest in Patents, Trademarks, Service Marks and Copyrights in the form attached hereto as Exhibit A with respect to each Patent, Copyright and Trademark that constitutes a patent application, registered or issued patent, trademark application, registered or issued trademark, service mark application, registered or issued service mark, copyright application or registered or issued copyright, and such other agreements, documents and instruments as the Agent shall from time to time reasonably request to reflect the security interest therein granted hereunder, and the Agent is hereby authorized to file each such Grant of Security Interest in Patents, Trademarks, Service Marks and Copyrights and each such document with the United States Patent and Trademark Office and the United States Copyright Office, as applicable, and any other applicable governmental agency in order to perfect the Agent’s security interest therein as granted hereunder. (b) Each Pledgor shall promptly execute and deliver to the Agent a Patent Assignment in the form attached hereto as Exhibit B, a Trademark and Service Mark Assignment in the form attached hereto as Exhibit C, and a Copyright Assignment in the form attached hereto as Exhibit D, in each case with respect to each patent application, patent, trademark application, trademark, service mark application, service mark, copyright application and copyright, and such other agreements, documents and instruments as the Agent shall from time to time reasonably request, permanently assigning all rights in the Patents, Trademarks and Copyrights to the Agent in the event any Event of Default shall have occurred and be continuing (the “Assignments”). The Assignments shall be held by the Agent, in escrow, until the occurrence of an Event of Default and, after and during the continuation of any such occurrence, {N0289348 2 }

the Agent may, at its sole option, record such escrowed Assignments with the United States Patent and Trademark Office and the United States Copyright Office, as applicable, and any other applicable governmental agency. 10. (a) Upon Payment in Full, this Agreement shall terminate. (b) A Pledgor shall automatically be released from its obligations hereunder (other than contingent obligations that survive the termination of the Secured Loan Documents as to which no claim has been asserted) in the circumstances set forth in Section 10.10(ii) of the Credit Agreement. (c) All Collateral sold or otherwise disposed of in a sale or other disposition or transfer permitted under Section 8.2.8 [Dispositions of Assets or Subsidiaries] or 8.2.7 [Liquidations, Mergers, Consolidations] of the Credit Agreement with respect to which the Pledgors shall have fully complied with all requirements and satisfied all conditions of the Secured Loan Documents shall automatically be released. (d) In connection with any termination or release pursuant to paragraph (a), (b) or (c) above, the Agent shall promptly execute and deliver to any Pledgor, at such Pledgor’s expense, all documents that such Pledgor shall reasonably request to evidence such termination or release and shall perform such other actions reasonably requested by such Pledgor to effect such release, including delivery of certificates, securities, instruments and the Assignments. Any execution and delivery of documents pursuant to this Section 10 shall be without recourse to or warranty by the Agent. (e) At any time that the Borrowers desire that the Agent take any of the actions described in the immediately preceding clause (d), they shall, upon request of the Agent, deliver to the Agent an officer’s certificate certifying that the release of the respective Pledgor is permitted pursuant to paragraph (a), (b) or (c) above. The Agent shall have no liability whatsoever to any Secured Party as a result of any release of any Pledgor by it as permitted (or which the Agent in good faith believes to be permitted) by this Section 10. (f) Notwithstanding anything to the contrary set forth in this Agreement, each Lender or Affiliate thereof that provides any Lender Provided Interest Rate Hedge or Other Lender Provided Financial Service Products by the acceptance of the benefits under this Agreement hereby acknowledges and agrees that any release of a Pledgor effected in the manner permitted by this Agreement shall not require the consent of any such Lender or Affiliate thereof. 11. Each Pledgor unconditionally agrees that the Agent and the Lenders shall be entitled to reimbursement of their expenses incurred hereunder as provided in Section 12.3.1 of the Credit Agreement. 12. Pledgor shall have the duty to prosecute diligently any patent applications included in the Patents, Trademarks and Copyrights pending as of the date of this Agreement if commercially reasonable in the reasonable judgment of such Pledgor or thereafter until the Debt shall have been Paid in Full, to make application on unpatented but patentable inventions {N0289348 2 }

(whenever it is commercially reasonable in the reasonable judgment of such Pledgor to do so) and to preserve and maintain all rights in patent applications and registered and issued patents included in the Patents, Trademarks and Copyrights, including the payment of all maintenance fees. Any expenses incurred in connection with such an application shall be borne by Pledgors. No Pledgor shall abandon any Patent, Trademark or Copyright that in the reasonable judgment of such Pledgor is material to the operation of the business without the consent of Agent, which shall not be unreasonably withheld. 13. Each Pledgor shall have the right to bring suit, action or other proceeding in its own name, and, with the Agent’s consent, to join Agent, if necessary, as a party to such suit, to enforce the Patents, Trademarks and Copyrights and any licenses thereunder. The Credit Agreement sets forth Pledgor’s rights to indemnification and reimbursement in connection with this Agreement. 14.

Each Pledgor hereby covenants and agrees as follows: 5.1 Such Pledgor shall do all reasonable acts that may be necessary and appropriate to maintain, preserve and protect the Pledged Collateral; such Pledgor shall be responsible for the risk of loss of, damage to, or destruction of the Pledged Collateral owned by such Pledgor, unless such loss is the result of the gross negligence or willful misconduct of the Administrative Agent; 5.2 Such Pledgor shall appear in and defend any action or proceeding of which such Pledgor is aware which could reasonably be expected to affect such Pledgor’s title to, or the Administrative Agent’s interest in, the Pledged Collateral or the proceeds thereof; provided, however, that with the consent of the Administrative Agent such Pledgor may settle such actions or proceedings with respect to the Pledged Collateral; 5.3 Such Pledgor shall, and shall cause each of the Companies to, keep separate, accurate and complete records of the Pledged Collateral, disclosing the Administrative Agent’s security interest hereunder; 5.4 Such Pledgor shall comply with all Laws applicable to the Pledged Collateral unless any noncompliance would not individually or in the aggregate materially impair the use or value of the Pledged Collateral or the Administrative Agent’s rights hereunder; 5.5 Such Pledgor shall pay any and all taxes, duties, fees or imposts of any nature imposed by any Official Body on any of the Pledged Collateral, except to the extent contested in good faith by appropriate proceedings; 5.6 Such Pledgor shall permit the Administrative Agent, its officers, employees and agents at reasonable times to inspect all books and records related to the Pledged Collateral; 5.7 Subject to Section 2(c) hereof, to the extent, following the date hereof, such Pledgor acquires capital stock, shares, securities, member interests, partnership interests and other ownership interests of any of the Companies or any of the rights, property or securities, shares, capital stock, member interests, partnership interests or any other ownership interests described in the definition of Pledged Collateral with respect to any of the Companies, such ownership interests shall be subject to the terms hereof and, upon such acquisition, shall be deemed to be hereby pledged to the Administrative Agent; and such Pledgor thereupon shall deliver all such securities, shares, capital stock, member interests, partnership interests and other ownership interests, together with an updated Schedule A hereto, to the Administrative Agent, together with all such control agreements, financing statements, and any other documents necessary to implement the provisions and purposes of this Agreement as the Administrative Agent may request; {N0289348 2 }

5.8 Except as permitted by the Credit Agreement, during the term of this Agreement, such Pledgor shall not sell, assign, replace, retire, transfer or otherwise dispose of its Pledged Collateral; 5.9 Such Pledgor will not change its state of incorporation, formation or organization, as applicable, without providing thirty (30) days prior written notice to the Administrative Agent; 5.10 Such Pledgor will not change its name without providing thirty (30) days prior written notice to the Administrative Agent; 5.11 Except as expressly set forth in the Credit Agreement, such Pledgor shall preserve its existence as a corporation, a limited liability company or a partnership, as applicable, and except as permitted by the Credit Agreement, shall not (i) in one transaction, or a series of related transactions, merge into or consolidate with any other entity, the survivor of which is not such Pledgor, or (ii) sell all or substantially all of its assets; and 5.12 During the term of this Agreement, such Pledgor shall not permit any Company to treat any uncertificated ownership interests as securities which are subject to Article 8 of the Code. 6. Other Rights With Respect to Pledged Collateral. In addition to the other rights with respect to the Pledged Collateral granted to the Administrative Agent hereunder, at any time and from time to time after and during the continuation of an Event of Default, the Administrative Agent, at its option and at the expense of the Pledgors, may (a) transfer into its own name, or into the name of its nominee, all or any part of the Pledged Collateral, thereafter receiving all dividends, income or other distributions upon the Pledged Collateral; (b) take control of and manage all or any of the Pledged Collateral; (c) apply to the payment of any of the Secured Obligations, whether any be due and payable or not, any moneys, including cash dividends and income from any Pledged Collateral, now or hereafter in the hands of the Administrative Agent, any Lender or any provider of Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, on deposit or otherwise, belonging to any Pledgor, as the Administrative Agent in its sole discretion shall determine; and (d) do anything which any Pledgor is required but fails to do hereunder. 7. Additional Remedies Upon Event of Default. Upon the occurrence of any Event of Default and while such Event of Default shall be continuing, the Administrative Agent shall have, in addition to all rights and remedies of a secured party under the Code or other applicable Law, and in addition to its rights under Section 6 above and under the other Loan Documents, the following rights and remedies: 7.1 The Administrative Agent may, after ten (10) days’ advance notice to a Pledgor, sell, assign, give an option or options to purchase or otherwise dispose of such Pledgor’s Pledged Collateral or any part thereof at public or private sale, at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Administrative Agent may deem commercially reasonable. Each Pledgor agrees that ten (10) days’ advance notice of the time and place of any public sale or the time after which any private {N0289348 2 }

sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Pledged Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Pledgor recognizes that the Administrative Agent may be compelled to resort to one or more private sales of the Pledged Collateral to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities, shares, capital stock, member interests, partnership interests or ownership interests for their own account for investment and not with a view to the distribution or resale thereof. 7.2 The proceeds of any collection, sale or other disposition of the Pledged Collateral, or any part thereof, shall, after the Administrative Agent has made all deductions of expenses, including attorneys’ fees and other expenses incurred in connection with repossession, collection, sale or disposition of such Pledged Collateral or in connection with the enforcement of the Administrative Agent’s rights with respect to the Pledged Collateral, including in any insolvency, bankruptcy or reorganization proceedings, be applied against the Secured Obligations, whether or not all the same be then due and payable, as set forth in Section 9.2.4 [Application of Proceeds] of the Credit Agreement. 8. Administrative Agent’s Duties. The powers conferred on the Administrative Agent hereunder are solely to protect its interest in the Pledged Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Pledged Collateral in its possession and the accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Pledged Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Pledged Collateral, except as otherwise provided by Law. 9. Additional Pledgors. It is anticipated that additional persons will from time to time become Subsidiaries of Holdings or another Loan Party, each of whom will be required to join this Pledge Agreement. It is acknowledged and agreed that new Subsidiaries of Holdings or of another Loan Party will become Pledgors hereunder and will be bound hereby by executing and delivering to Administrative Agent (i) a Guarantor Joinder in the form of Exhibit 1.1(G)(1) to the Credit Agreement and (ii) a Pledgor Joinder in the form attached hereto as Exhibit A. In addition, a new Schedule A hereto shall be provided to Administrative Agent showing the pledge of the ownership interest in such new Subsidiary and any ownership interests that such new Subsidiary owns in any other Person. 10. No Waiver; Cumulative Remedies. No failure to exercise, and no delay in exercising, on the part of the Administrative Agent, any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any further exercise {N0289348 2 }

thereof or the exercise of any other right, power or privilege. The remedies herein provided are cumulative and not exclusive of any remedies provided under the other Loan Documents or by Law. Each Pledgor waives any right to require the Administrative Agent to proceed against any other Person or to exhaust any of the Pledged Collateral or other security for the Secured Obligations or to pursue any remedy in the Administrative Agent’s power. 11. No Discharge Until Indefeasible Payment of the Secured Obligations. The pledge, security interests, and other Liens and the obligations of each Pledgor hereunder shall not be discharged or impaired or otherwise diminished by any failure, default, omission, or delay, willful or otherwise, by Administrative Agent, or any other obligor on any of the Secured Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Pledgor or which would otherwise operate as a discharge of such Pledgor as a matter of law or equity. Without limiting the generality of the foregoing, each Pledgor hereby consents to, and the pledge, security interests, and other Liens given by such Pledgor hereunder shall not be diminished, terminated, or otherwise similarly affected by any of the following at any time and from time to time, except as otherwise provided by Law: 11.1 Any lack of genuineness, legality, validity, enforceability, or allowability (in a bankruptcy, insolvency, reorganization or similar proceeding, or otherwise), or any avoidance or subordination, in whole or in part, of any Loan Document, any obligations in connection with any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations and regardless of any Law, regulation, or order now or hereafter in effect in any jurisdiction affecting any of the Secured Obligations, any of the terms of the Loan Documents, or any rights of the Administrative Agent or any other Person with respect thereto; 11.2 Any increase, decrease, or change in the amount, nature, type or purpose of any of or any release, surrender, exchange, compromise or settlement of any of the Secured Obligations (whether or not contemplated by the Loan Documents as presently constituted); any change in the time, manner, method, or place of payment or performance of, or in any other term of, any of the Secured Obligations; any execution or delivery of any additional Loan Documents; or any amendment, modification or supplement to, or refinancing or refunding of, any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations; 11.3 Any failure to assert any breach of or default under any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations; any extensions of credit in excess of the amount committed under or contemplated by the Loan Documents or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or in circumstances in which any condition to such extensions of credit has not been satisfied; any other exercise or non-exercise, or any other failure, omission, breach, default, delay, or wrongful action in connection with any exercise or non-exercise, of any right or remedy against such Pledgor or any other Person under or in connection with any Loan Document or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations; any refusal {N0289348 2 }

of payment or performance of any of the Secured Obligations, whether or not with any reservation of rights against any Pledgor; or any application of collections (including collections resulting from realization upon any direct or indirect security for the Secured Obligations) to other obligations, if any, not entitled to the benefits of this Agreement, in preference to Secured Obligations or, if any collections are applied to Secured Obligations, any application to particular Secured Obligations; 11.4 Any taking, exchange, amendment, modification, supplement, termination, subordination, release, loss, or impairment of, or any failure to protect, perfect, or preserve the value of, or any enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or any failure, omission, breach, default, delay, or wrongful action by the Administrative Agent or any other Person in connection with the enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or, any other action or inaction by Administrative Agent or any other Person in respect of, any direct or indirect security for any of the Secured Obligations (including the Pledged Collateral). As used in this Agreement, “direct or indirect security” for the Secured Obligations, and similar phrases, includes any collateral security, guaranty, suretyship, letter of credit, capital maintenance agreement, put option, subordination agreement, or other right or arrangement of any nature providing direct or indirect assurance of payment or performance of any of the Secured Obligations, made by or on behalf of any Person; 11.5 Except as expressly permitted by the Credit Agreement, any merger, consolidation, liquidation, dissolution, winding-up, charter revocation, or forfeiture, or other change in, restructuring or termination of the corporate structure or existence of, any Pledgor or Holdings or any other Person; any bankruptcy, insolvency, reorganization or similar proceeding with respect to any Pledgor or Holdings or any other Person; or any action taken or election (including any election under Section 1111(b)(2) of the United States Bankruptcy Code or any comparable law of any jurisdiction) made by Administrative Agent or any Pledgor or Holdings or by any other Person in connection with any such proceeding; 11.6 Any defense, setoff, or counterclaim which may at any time be available to or be asserted by any Pledgor or Holdings or any other Person with respect to any Loan Document or any of the Secured Obligations; or any discharge by operation of law or release of any Pledgor or Holdings or any other Person from the performance or observance of any Loan Document or any of the Secured Obligations; and 11.7 Any other event or circumstance, whether similar or dissimilar to the foregoing, and whether known or unknown, which might otherwise constitute a defense available to, or limit the liability of a guarantor or a surety, including any Pledgor, excepting only full, strict, and indefeasible payment and performance of the Secured Obligations in full. {N0289348 2 }

12. The terms of Section 5.9 of the Credit Agreement are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 13. Waivers. Each Pledgor hereby waives any and all defenses which any Pledgor may now or hereafter have based on principles of suretyship, impairment of collateral, or the like and each Pledgor hereby waives any defense to or limitation on its obligations under this Agreement arising out of or based on any event or circumstance referred to in the immediately preceding section hereof. Without limiting the generality of the foregoing and to the fullest extent permitted by applicable Law, each Pledgor hereby further waives each of the following: 13.1 All notices, disclosures and demands of any nature which otherwise might be required from time to time to preserve intact any rights against such Pledgor, including the following: any notice of any event or circumstance described in the immediately preceding section hereof; any notice required by any Law, regulation or order now or hereafter in effect in any jurisdiction; any notice of nonpayment, nonperformance, dishonor, or protest under any Loan Document or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations; any notice of the incurrence of any Secured Obligations; any notice of any default or any failure on the part of such Pledgor or Holdings or any other Person to comply with any Loan Document or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products or any of the Secured Obligations or any requirement pertaining to any direct or indirect security for any of the Secured Obligations; and any notice or other information pertaining to the business, operations, condition (financial or otherwise), or prospects of Holdings or any other Person; 13.2 Any right to any marshalling of assets, to the filing of any claim against such Pledgor or Holdings or any other Person in the event of any bankruptcy, insolvency, reorganization, or similar proceeding, or to the exercise against such Pledgor or Holdings, or any other Person of any other right or remedy under or in connection with any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations or any direct or indirect security for any of the Secured Obligations; any requirement of promptness or diligence on the part of the Administrative Agent or any other Person; any requirement to exhaust any remedies under or in connection with, or to mitigate the damages resulting from default under, any Loan Document or any of the Secured Obligations or any direct or indirect security for any of the Secured Obligations; any benefit of any statute of limitations; and any requirement of acceptance of this Agreement or any other Loan Document, and any requirement that any Pledgor receive notice of any such acceptance; and 13.3 Any defense or other right arising by reason of any Law now or hereafter in effect in any jurisdiction pertaining to election of remedies (including anti-deficiency Laws, “one action” Laws, or the like), or by reason of any election of remedies or other action or inaction by the Administrative Agent (including commencement or completion of any judicial proceeding or nonjudicial sale or other action in respect of collateral security for any of the Secured Obligations), which results in denial or impairment of the right of the Administrative Agent to {N0289348 2 }

seek a deficiency against Holdings, another Loan Party or any other Person or which otherwise discharges or impairs any of the Secured Obligations. 14. Assignment. All rights of the Administrative Agent under this Agreement shall inure to the benefit of its successors and assigns.

Specific Performance. Each Pledgor acknowledges and agrees that, in addition to the other rights of the Administrative Agent hereunder and under the other Loan Documents, because the Administrative Agent’s remedies at law for failure of such Pledgor to comply with the provisions hereof relating to the Administrative Agent’s rights (i) to inspect the books and records related to the Pledged Collateral, (ii) to receive the various notifications such Pledgor is required to deliver hereunder, (iii) to obtain copies of agreements and documents as provided herein with respect to the Pledged Collateral, (iv) to enforce the provisions hereof pursuant to which the such Pledgor has appointed the Administrative Agent its attorney-in-fact, and (v) to enforce the Administrative Agent’s remedies hereunder, would be inadequate and that any such failure would not be adequately compensable in damages, such Pledgor agrees that each such provision hereof may be specifically enforced. {N0289348 2 }

19. Voting Rights in Respect of the Pledged Collateral. So long as no Event of Default shall occur and be continuing under the Credit Agreement, each Pledgor may exercise any and all voting and other consensual rights pertaining to the Pledged Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement or the other Loan Documents; provided, however, that such Pledgor will not exercise or will refrain from exercising any such voting and other consensual right pertaining to the Pledged Collateral, as the case may be, if such action would have a material adverse effect on the value of any Pledged Collateral. Subject to the express terms and conditions of the Credit Agreement and without limiting the generality of the foregoing and in addition thereto, the Pledgors shall not vote to enable, or take any other action to permit, any of the Companies to issue any stock, member interests, partnership interests or other equity securities, member interests, partnership interests or other ownership interests of any nature or to issue any other securities, shares, capital stock, member interests, partnership interests or other ownership interests convertible into or granting the right to purchase or exchange for any stock, member interests, partnership interests or other equity securities, member interests, partnership interests or other ownership interests of any nature of any such Company or to enter into any agreement or undertaking restricting the right or ability of the Pledgor or the Administrative Agent to sell, assign or transfer any of the Pledged Collateral. 20. No Novation. The provisions of Section 12.13(a) of the Credit Agreement regarding novation are hereby incorporated by reference and shall apply mutatis mutandis with respect to the other provisions of this Agreement 21. Entire Agreement; Amendments. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements relating to a grant of a security interest in the Pledged Collateral by any Pledgor. This Agreement may not be amended or supplemented except by a writing signed by the Administrative Agent and the Pledgors. 22. Counterparts; Telecopy Signatures. This Agreement may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same instrument. Each Pledgor acknowledges and agrees that a telecopy transmission to the Administrative Agent or any Lender of, or the e-mail delivery of a portable document format (PDF) file to the Agent or any Lender containing, the signature pages hereof purporting to be signed on behalf of any Pledgor shall constitute effective and binding execution and delivery hereof by such Pledgor. 23.

In addition to the foregoing, within ten (10) days of the Administrative Agent's request, each Loan Party shall execute and deliver to the Administrative Agent all documents or materials of any {N0289348 2 }

Loan Party necessary or appropriate in order to comply with the Assignment of Claims Act (the "Government Contract Assignments") in connection with each Government Contract which is required to be assigned to the Administrative Agent by the Administrative Agent.

Each Debtor assumes full responsibility for taking any and all necessary steps to preserve the Administrative Agent’s and the Lenders’ rights with respect to the Collateral against all Persons other than anyone asserting rights in respect of a Permitted Lien. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Administrative Agent takes such action for {N0289348 2 }

that purpose as such Debtor shall reasonably request in writing, provided that such requested action will not, in the judgment of the Administrative Agent, impair the security interest in the Collateral created hereby or the Administrative Agent’s and the Lenders’ rights in, or the value of, the Collateral, and provided further that such written request is received by the Administrative Agent in sufficient time to permit the Administrative Agent to take the requested action. 7. The pledge, security interests, and other Liens and the obligations of each Debtor hereunder shall not be discharged or impaired or otherwise diminished by any failure, default, omission, or delay, willful or otherwise, by Administrative Agent, or any other obligor on any of the Secured Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Debtor or which would otherwise operate as a discharge of such Debtor as a matter of law or equity. Without limiting the generality of the foregoing, each Debtor hereby consents to, and the pledge, security interests, and other Liens given by such Debtor hereunder shall not be diminished, terminated, or otherwise similarly affected by any of the following at any time and from time to time: (a) Any lack of genuineness, legality, validity, enforceability, or allowability (in a bankruptcy, insolvency, reorganization or similar proceeding, or otherwise), or any avoidance or subordination, in whole or in part, of any Loan Document, any obligations in connection with any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations and regardless of any Law, regulation, or order now or hereafter in effect in any jurisdiction affecting any of the Secured Obligations, any of the terms of the Loan Documents, or any rights of the Administrative Agent or any other Person with respect thereto; (b) Any increase, decrease, or change in the amount, nature, type or purpose of any of or any release, surrender, exchange, compromise or settlement of any of the Secured Obligations (whether or not contemplated by the Loan Documents as presently constituted); any change in the time, manner, method, or place of payment or performance of, or in any other term of, any of the Secured Obligations; any execution or delivery of any additional Loan Documents; or any amendment, modification or supplement to, or refinancing or refunding of, any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations; (c) Any failure to assert any breach of or default under any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations; any extensions of credit in excess of the amount committed under or contemplated by the Loan Documents or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or in circumstances in which any condition to such extensions of credit has not been satisfied; any other exercise or non-exercise, or any other failure, omission, breach, default, delay, or wrongful action in connection with any exercise or non-exercise, of any right or remedy against such Debtor or any other Person under or in connection with any Loan Document or any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations; any refusal of payment or performance of any of the Secured Obligations, whether or not with any {N0289348 2 }

reservation of rights against any Debtor; or any application of collections (including collections resulting from realization upon any direct or indirect security for the Secured Obligations) to other obligations, if any, not entitled to the benefits of this Agreement, in preference to Secured Obligations or, if any collections are applied to Secured Obligations, any application to particular Secured Obligations; (d) Any taking, exchange, amendment, modification, supplement, termination, subordination, release, loss, or impairment of, or any failure to protect, perfect, or preserve the value of, or any enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or any failure, omission, breach, default, delay, or wrongful action by the Administrative Agent or any other Person in connection with the enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or, any other action or inaction by Administrative Agent or any other Person in respect of, any direct or indirect security for any of the Secured Obligations (including the Collateral).

Each Debtor hereby waives any and all defenses which any Debtor may now or hereafter have based on principles of suretyship, impairment of collateral, or the like and each Debtor hereby waives any defense to or limitation on its obligations under this Agreement arising out of or based on any event or circumstance referred to in the immediately preceding section hereof. Without limiting the generality of the foregoing and to the fullest extent permitted by applicable Law, each Debtor hereby further waives each of the following: {N0289348 2 }

(a) All notices, disclosures and demands of any nature which otherwise might be required from time to time to preserve intact any rights against such Debtor, including the following: any notice of any event or circumstance described in the immediately preceding section hereof; any notice required by any Law, regulation or order now or hereafter in effect in any jurisdiction; any notice of nonpayment, nonperformance, dishonor, or protest under any Loan Document, under any Lender Provided Interest Rate Hedge, or under any Other Lender Provided Financial Service Products or any of the Secured Obligations; any notice of the incurrence of any Secured Obligations; any notice of any default or any failure on the part of such Debtor or Holdings or any other Person to comply with any Loan Document, any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products, or any of the Secured Obligations or any requirement pertaining to any direct or indirect security for any of the Secured Obligations; and any notice or other information pertaining to the business, operations, condition (financial or otherwise), or prospects of Holdings or any other Person; (b) Any right to any marshalling of assets, to the filing of any claim against such Debtor or Holdings or any other Person in the event of any bankruptcy, insolvency, reorganization, or similar proceeding, or to the exercise against such Debtor or Holdings, or any other Person of any other right or remedy under or in connection with any Loan Document, any Lender Provided Interest Rate Hedge, or any Other Lender Provided Financial Service Products or any of the Secured Obligations or any direct or indirect security for any of the Secured Obligations; any requirement of promptness or diligence on the part of the Administrative Agent or any other Person; any requirement to exhaust any remedies under or in connection with, or to mitigate the damages resulting from default under, any Loan Document or any of the Secured Obligations or any direct or indirect security for any of the Secured Obligations; any benefit of any statute of limitations; and any requirement of acceptance of this Agreement or any other Loan Document, and any requirement that any Debtor receive notice of any such acceptance; and (c) Any defense or other right arising by reason of any Law now or hereafter in effect in any jurisdiction pertaining to election of remedies (including anti-deficiency Laws, “one action” Laws, or the like), or by reason of any election of remedies or other action or inaction by the Administrative Agent (including commencement or completion of any judicial proceeding or nonjudicial sale or other action in respect of collateral security for any of the Secured Obligations), which results in denial or impairment of the right of the Administrative Agent to seek a deficiency against Holdings or any other Person or which otherwise discharges or impairs any of the Secured Obligations. 9. The Obligations and additional liabilities of the Debtors under this Agreement are joint and several obligations of the Debtors, and each Debtor hereby waives to the full extent permitted by Law any defense it may otherwise have to the payment and performance of the Obligations and such additional liabilities that its liability hereunder is limited and not joint and several. Each Debtor acknowledges and agrees that the foregoing waivers serve as a material inducement to the agreement of the Administrative Agent and the Lenders to make the Loans, and that the Administrative Agent and the Lenders are relying on each specific waiver and all such waivers in entering into this Agreement. The undertakings of each Debtor hereunder secure the obligations of itself and the other Debtors. The Administrative Agent and the Lenders, or any of them, may, in their sole discretion, elect to enforce this Agreement against {N0289348 2 }

any Debtor without any duty or responsibility to pursue any other Debtor and such an election by the Administrative Agent and the Lenders, or any of them, shall not be a defense to any action the Administrative Agent and the Lenders, or any of them, may elect to take against any Debtor. Each of the Lenders and Administrative Agent hereby reserve all rights against each Debtor. 10. (a) At any time and from time to time whether or not an Event of Default then exists and without prior notice to or consent of any Debtor, the Administrative Agent may at its option take such actions as the Administrative Agent deems appropriate (i) to attach, perfect, continue, preserve and protect the Administrative Agent’s and the Lenders’ first priority security interest in or lien on the Collateral, and/or (ii) subject to the limitations provided for in the Credit Agreement, to inspect, audit and verify the Collateral, including reviewing all of such Debtor’s books and records and copying and making excerpts therefrom, provided that prior to an Event of Default or a Potential Default, the same is done with advance notice during normal business hours to the extent access to such Debtor’s premises is required, and (iii) to add all liabilities, obligations, costs and expenses reasonably incurred in connection with the foregoing clauses (i) and (ii) to the Secured Obligations, to be paid by the Debtors or any Debtor to the Administrative Agent for the benefit of the Administrative Agent and the Lenders upon demand. (b) At any time and from time to time after an Event of Default exists and is continuing and without prior notice to or consent of any Debtor, the Administrative Agent may at its option take such actions as the Administrative Agent deems appropriate (i) to maintain, repair, protect and insure the Collateral, and/or (ii) to perform, keep, observe and render true and correct any and all covenants, agreements, representations and warranties of any Debtor hereunder, and (iii) to add all liabilities, obligations, costs and expenses reasonably incurred in connection with the foregoing clauses (i) and (ii) to the Secured Obligations, to be paid by the Debtors or any Debtor to the Administrative Agent for the benefit of the Administrative Agent and the Lenders upon demand. 11. After there exists any Event of Default under the Credit Agreement: (a) The Administrative Agent shall have and may exercise all the rights and remedies available to a secured party under the Code in effect at the time, and such other rights and remedies as may be provided by Law and as set forth below, including to take over and collect all of any Debtor’s Receivables and all other Collateral, and to this end each Debtor hereby appoints the Administrative Agent, its officers, employees and agents, as its irrevocable, true and lawful attorneys-in-fact with all necessary power and authority to (i) take possession immediately, with or without notice, demand, or legal process, of any of or all of the Collateral wherever found, and for such purposes, enter upon any premises upon which the Collateral may be found and remove the Collateral therefrom, (ii) require any Debtor to assemble the Collateral and deliver it to the Administrative Agent or to any place designated by the Administrative Agent at such Debtor’s expense, (iii) receive, open and dispose of all mail addressed to any Debtor and notify postal authorities to change the address for delivery thereof to such address as the Administrative Agent may designate, (iv) demand payment of the Receivables, (v) enforce payment of the Receivables by legal proceedings or otherwise, (vi) exercise all of any Debtor’s rights and remedies with respect to the collection of the Receivables, (vii) settle, adjust, {N0289348 2 }

This power of attorney, being coupled with an interest, shall be irrevocable for the life of this Agreement. To the extent permitted by Law, each Debtor hereby waives all claims of damages due to or arising from or connected with any of the rights or remedies exercised by the Administrative Agent pursuant to this Agreement, except claims for physical damage to the Collateral arising from gross negligence or willful misconduct by the Administrative Agent. (b) The Administrative Agent shall have the right to lease, sell or otherwise dispose of all or any of the Collateral at public or private sale or sales for cash, credit or any combination thereof, with such notice as may be required by Law (it being agreed by each Debtor that, in the absence of any contrary requirement of Law, ten (10) days’ prior notice of a public or private sale of Collateral shall be deemed reasonable notice), in lots or in bulk, for cash or on credit, all as the Administrative Agent, in its sole discretion, may deem advisable. Such sales may be adjourned from time to time with or without notice. The Administrative Agent shall have the right to conduct such sales on any Debtor’s premises or elsewhere and shall have the right to use any Debtor’s premises without charge for such sales for such time or times as the Administrative Agent may see fit. The Administrative Agent may purchase all or any part of the Collateral at public or, if permitted by Law, private sale and, in lieu of actual payment of such purchase price, may set off the amount of such price against the Secured Obligations. (c) Each Debtor, at its cost and expense (including the cost and expense of any of the following referenced consents, approvals, etc.) will promptly execute and deliver or cause the execution and delivery of all applications, certificates, instruments, registration statements, and all other documents and papers the Administrative Agent may request in connection with the obtaining of any consent, approval, registration, qualification, permit, license, accreditation, or authorization of any other Official Body or other Person necessary or appropriate for the {N0289348 2 }

effective exercise of any rights hereunder or under the other Loan Documents. Without limiting the generality of the foregoing, each Debtor agrees that in the event the Administrative Agent on behalf of itself and/or the Lenders shall exercise its rights hereunder or pursuant to the other Loan Documents, to sell, transfer, or otherwise dispose of, or vote, consent, operate, or take any other action in connection with, any of the Collateral, such Debtor shall execute and deliver (or cause to be executed and delivered) all applications, certificates, assignments and other documents that the Administrative Agent requests to facilitate such actions and shall otherwise promptly, fully, and diligently cooperate with the Administrative Agent and any other Persons in making any application for the prior consent or approval of any Official Body or any other Person to the exercise by the Administrative Agent on behalf of itself and/or the Lenders of any such rights relating to all or any of the Collateral. Furthermore, because each Debtor agrees that the remedies at Law, of the Administrative Agent on behalf of itself and/or the Lenders, for failure of such Debtor to comply with this Subsection (c) would be inadequate, and that any such failure would not be adequately compensable in damages, each Debtor agrees that this Subsection (c) may be specifically enforced. (d) The Administrative Agent may request, without limiting the rights and remedies of the Administrative Agent on behalf of itself and the Lenders otherwise provided hereunder and under the other Loan Documents, that each Debtor do any of the following: (i) give the Administrative Agent on behalf of itself and the Lenders specific assignments of the accounts receivable of such Debtor after such accounts receivable come into existence, and schedules of such accounts receivable, the form and content of such assignment and schedules to be satisfactory to Administrative Agent, and (ii) in order to better secure the Administrative Agent on behalf of itself and the Lenders, to the extent permitted by Law, enter into such lockbox agreements and establish such lockbox accounts as the Administrative Agent may require, all at the sole expense of such Debtor and shall direct all payments from all payors due to such Debtor, to such lockbox accounts. 12. To the extent that applicable law imposes duties on Administrative Agent to exercise remedies in a commercially reasonable manner, each Debtor acknowledges and agrees that it is not commercially unreasonable for Administrative Agent (a) to fail to incur expenses reasonably deemed significant by Administrative Agent to prepare Collateral for disposition or otherwise to fail to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other Persons obligated on Collateral or to fail to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other Persons, whether or not in the same business as any Debtor, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers {N0289348 2 }

of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure Administrative Agent against risks of loss, collection or disposition of Collateral or to provide to Administrative Agent a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by Administrative Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Administrative Agent in the collection or disposition of any of the Collateral. Each Debtor acknowledges that the purpose of this Section 12 is to provide non-exhaustive indications of what actions or omissions by Administrative Agent would fulfill Administrative Agent’s duties under the Code or the Uniform Commercial Code of any other relevant jurisdiction in Administrative Agent’s exercise of remedies against the Collateral and that other actions or omissions by Administrative Agent shall not be deemed to fail to fulfill such duties solely on account of not being indicated in this Section 12. Without limitation upon the foregoing, nothing contained in this Section 12 shall be construed to grant any rights to any Debtor or to impose any duties on Administrative Agent that would not have been granted or imposed by this Agreement or by applicable Law in the absence of this Section 12. 13. The lien on and security interest in each Debtor’s Collateral granted to and created in favor of the Administrative Agent by this Agreement shall be for the benefit of the Administrative Agent and the Lenders and any provider of any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products. Each of the rights, privileges, and remedies provided to the Administrative Agent hereunder or otherwise by Law with respect to any Debtor’s Collateral shall be exercised by the Administrative Agent only for its own benefit and the benefit of the Lenders, and any of such Debtor’s Collateral or proceeds thereof held or realized upon at any time by the Administrative Agent shall be applied as set forth in Section 9.2.4 [Application of Proceeds] of the Credit Agreement. Each Debtor shall remain liable to the Administrative Agent and the Lenders and any provider of any Lender Provided Interest Rate Hedge or any Other Lender Provided Financial Service Products for and shall pay to the Administrative Agent for the benefit of itself and the Lenders and any such provider any deficiency which may remain after such sale or collection. 14. Reserved. 15. Upon indefeasible payment in full of the Secured Obligations, the expiration of all Commitments and Letters of Credit, and termination of the Credit Agreement, this Agreement shall terminate and be of no further force and effect, and the Administrative Agent shall thereupon promptly return to a Debtor such of the Collateral and such other documents delivered by such Debtor hereunder as may then be in the Administrative Agent’s possession, subject to the rights of third parties. Until such time, however, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. 16. No failure or delay on the part of the Administrative Agent in exercising any right, remedy, power or privilege hereunder shall operate as a waiver thereof or of any other right, remedy, power or privilege of the Administrative Agent hereunder; nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. No waiver of a {N0289348 2 }

single Event of Default shall be deemed a waiver of a subsequent Event of Default. All waivers under this Agreement must be in writing. The rights and remedies of the Administrative Agent under this Agreement are cumulative and in addition to any rights or remedies which it may otherwise have, and the Administrative Agent may enforce any one or more remedies hereunder successively or concurrently at its option. 17. All notices, statements, requests and demands given to or made upon either party hereto in accordance with the provisions of this Agreement shall be given or made as provided in Section 12.5 [Notices; Effectiveness; Electronic Communication] of the Credit Agreement. 18. Each Debtor agrees that as of the date hereof, all information contained on the Security Interest Data Schedule attached hereto as Schedule A is accurate and complete and contains no omission or misrepresentation. Each Debtor shall promptly notify the Administrative Agent of any changes in the information set forth thereon. 19. Each Debtor acknowledges that the provisions hereof giving the Administrative Agent rights of access to books, records and information concerning the Collateral and such Debtor’s operations and providing the Administrative Agent access to such Debtor’s premises are intended to afford the Administrative Agent with immediate access to current information concerning such Debtor and its activities, including the value, nature and location of the Collateral so that the Administrative Agent can, among other things, make an appropriate determination after the occurrence of an Event of Default, whether and when to exercise its other remedies hereunder and at Law, including instituting a replevin action should any Debtor refuse to turn over any Collateral to the Administrative Agent. Each Debtor further acknowledges that should such Debtor at any time fail to promptly provide such information and access to the Administrative Agent, each Debtor acknowledges that the Administrative Agent would have no adequate remedy at Law to promptly obtain the same. Each Debtor agrees that the provisions hereof may be specifically enforced by the Administrative Agent and waives any claim or defense in any such action or proceeding that the Administrative Agent has an adequate remedy at Law. 20. This Agreement is subject to modification only by a writing signed by the parties. This Agreement shall be binding upon and inure to the benefit of the Administrative Agent, the Lenders and their respective successors and assigns, and each Debtor and each of its respective successors and assigns, except that no Debtor may assign or transfer such Debtor’s rights or obligations hereunder or any interest herein and any such purported assignment or transfer shall be null and void. 21. The terms of Section 12.11 [Choice of Law; Submission to Jurisdiction; Waiver of Venue; Service of Process; Waiver of Jury Trial] of the Credit Agreement with respect to governing law, submission to jurisdiction, venue, service of process and waiver of jury trial are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 22. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. {N0289348 2 }

23. This Agreement and the Pledge Agreement (to the extent any of the Collateral is included in the Pledged Collateral as defined in the Pledge Agreement) constitute the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements relating to a grant of a security interest in the Collateral by any Debtor. 24. This Agreement may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same instrument. Each Debtor acknowledges and agrees that a telecopy transmission to the Administrative Agent or any Lender of, or the e-mail delivery of a portable document format (PDF) file to the Administrative Agent or any Lender containing, the signature pages hereof purporting to be signed on behalf of any Debtor shall constitute effective and binding execution and delivery hereof by such Debtor.
