This Amendment will become effective on the date (the “Third Amendment Effective Date”) on which each of the following conditions have been satisfied (in form and substance satisfactory to each Lender, or waived by each Lender) in accordance with the terms therein:

(a)

Amendment. The execution and delivery of this Amendment by each Loan Party, the Agent and each Lender;

(b)

No Default. No Default or Event of Default exists as of the date hereof after giving effect to this Amendment; and

5.Payment of Lenders’ Expenses. Borrower shall pay all Lenders’ Expenses and other amounts due and payable under the Loan Documents to the Agent and the Lenders (to the extent invoiced on or prior to the date hereof) on the Third Amendment Effective Date. To the extent any such Lender Expenses incurred on or prior to the date hereof shall not have been invoiced on or prior to the Third Amendment Effective Date, the Borrower shall pay all such Lender Expenses within five (5) Business Days of receipt of any invoice for such Lender Expenses. Notwithstanding any other provision herein or in any other Loan Document, the failure by Borrower to make the payment required pursuant to this Section 5 shall result in an immediate Event of Default without any further action by any other Person.

6.Representations and Warranties. Each Loan Party hereby represents and warrants as of the Third Amendment Effective Date to Agent and each Lender as follows:

(a)

each Loan Party and each of its Subsidiaries is a corporation, partnership or limited liability company duly organized, validly existing and in good standing under the laws of its state of incorporation or formation;

(a)

the representations and warranties contained in the Loan Agreement and the other Loan Documents are true and correct in all material respects (or, in the case of any representation or warranty that is, by its terms qualified by materiality, in all respects) on and as of the Third Amendment Effective Date, except to the extent that any such representation or warranty relates to a specific earlier date in which case such representation or warranty shall be true and correct in all material respects (or, in the case of any representation or warranty that is, by its terms qualified by materiality, in all respects) as of such earlier date, in each case, after giving effect to this Amendment.

7.Loan Documents in Full Force and Effect. The Loan Agreement and the other Loan Documents shall remain in full force and effect and are hereby ratified and confirmed in all respects, and each Loan Party hereby reaffirms the Obligations and any and all guarantees, security interests and Liens it has granted (or made) to secure the Obligations. Each such Obligation, guarantee, security interest and Lien is reaffirmed and shall remain and continue in full force and effect in accordance with its terms notwithstanding this Amendment and shall include and extend to any new obligations assumed by any Loan Party under this Amendment or otherwise under the Loan Documents. The validity and enforceability of the appointment of the Agent as proxy and attorney-in-fact under Section 10.3 of the Loan Agreement is ratified and reaffirmed as of the date hereof, and to the extent expressly contemplated by such provision and subject to the limitations set forth therein, each Loan Party reappoints the Agent as its proxy and attorney-in-fact in accordance with the terms of such provisions, as applicable, which appointment is irrevocable and coupled with an interest and shall terminate only on the Termination Date, for the purpose of carrying out the provisions of such Loan Documents, as applicable.

All references to the Loan Agreement shall be deemed to mean the Loan Agreement as modified hereby. For the avoidance of doubt, all modifications of the Loan Agreement provided for in this Amendment shall apply to all Term Loans, including the Closing Date Term Loan, the First Amendment Term Loan and the Delayed Draw Term Loans, and shall survive any repayment or prepayment of the First Amendment Term Loan and the Delayed Draw Term Loans. This Amendment shall not constitute a novation or satisfaction and accord of the Loan Agreement and the other Loan Documents. The parties hereto agree to be bound by the terms and conditions of the Loan Agreement and the Loan Documents as modified by this Amendment, as though such terms and conditions were set forth herein. Each reference in the Loan Agreement to “this Agreement,” “hereunder,” “hereof,” “herein” or words of similar import shall mean and be a reference to the Loan Agreement as modified by this Amendment, and each reference herein or in any other Loan Document to the “Loan Agreement” shall mean and be a reference to the Loan Agreement as modified by this Amendment.

8.Release. Each Loan Party hereby waives, remises, releases, acquits, satisfies and forever discharges the Agent and each Lender, their respective agents, employees, officers, directors, predecessors, attorneys and all others acting or purporting to act on behalf of or at the direction of the Agent or any Lender (“Releasees”), of and from any and all manner of known and unknown actions, causes of action, suits, debts, accounts, covenants, contracts, controversies, agreements, variances, damages, judgments, claims and demands whatsoever, whether in law or in equity, which any of such parties ever had, now has or, to the extent arising from or in connection with any act, omission or state of facts taken or existing on or prior to the date hereof, may have after the date hereof against the Releasees, for, upon or by reason of any matter, cause or thing whatsoever in connection with the Obligations or the Loan Documents through the date hereof. Without limiting the generality of the foregoing, each Loan Party waives and affirmatively agrees not to allege or otherwise pursue any defenses, affirmative defenses, counterclaims, claims, causes of action, setoffs or other rights they do, shall or may have in connection with the Obligations or the Loan Documents as of the date hereof, including, but not limited to, the rights to contest any conduct of the Releasees relating to or arising out of the Loan Agreement or the other Loan Documents on or prior to the date hereof.

9.Direction to Agent. The undersigned Lenders hereby represent and warrant that they constitute all Lenders as of the date hereof and hereby direct and authorize the Agent to execute this Amendment.

10.Counterparts. This Amendment may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Amendment. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature (including an electronic signature) shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

11.Successors and Assigns. This Amendment shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties; provided, however, that neither this Amendment nor any rights, benefits, obligations or duties hereunder or under any of the other Loan Documents may be assigned, transferred, hypothecated or otherwise conveyed by any Loan Party without the prior express written consent of Agent and the Required Lenders. Any such purported assignment, transfer, hypothecation or other conveyance by any Loan Party without the prior express written consent of Agent and the Required Lenders shall be void.

12.CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICAIL REFERENCE. IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, THIS AMENDMENT, THE OTHER LOAN DOCUMENTS AND THE OBLIGATIONS SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET FORTH IN SECTION 12 OF THE LOAN AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS MUTANDIS.
