NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of all of which is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. <u>Amendment to Credit Agreement</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The definition of "Maturity Date" in Section 1.01 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

SECTION 2. <u>Representations and Warranties</u>. Each of the Loan Parties hereby represents and warrants on the Amendment Effective Date that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Loan Parties (i) is a corporation, limited liability company or limited partnership, as applicable, duly organized, validly existing and in good standing under the laws of the state or jurisdiction of its organization, (ii) has all requisite power and authority to conduct its business as now conducted and as presently contemplated and, in the case of the Borrower, to make the borrowings hereunder, and to execute and deliver this Amendment, and to consummate the transactions contemplated thereby, and (iii) is duly qualified to do business and is in good standing in each jurisdiction other than the state or jurisdiction of its organization in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary, except (solely for the purposes of this subclause (iii)) where the failure to be so qualified and in good standing could reasonably be expected to have a Material Adverse Effect. The Borrower and its Subsidiaries have obtained, and are in compliance with, all licenses, permits, approvals and other authorizations necessary for the operation of their business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The execution, delivery and performance by each Loan Party of this Amendment, (i) has been duly authorized by all necessary action, (ii) does not and will not contravene (A) any of its Governing Documents, (B) any applicable Requirement of Law or (C) any Contractual Obligation binding on or otherwise affecting it or any of its properties, (iii) does not and will not result in or require the creation of any Lien (other than pursuant to this Amendment) upon or with respect to any of its properties, except, in the case of clause (ii)(C), to the extent where such contravention, default, noncompliance, suspension, revocation, impairment, forfeiture or nonrenewal could not reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required in connection with the due execution, delivery and performance by any Loan Party of this Amendment other than any authorization, approval, notice or filing or other action as has been previously been obtained or taken and remains in full force and effect on the Amendment Effective Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Amendment is a legal, valid and binding obligation of each Loan Party, enforceable against each, such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and by general principles of equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The representations and warranties of the Borrower and each other Loan Party contained in <u>Article V</u> of the Credit Agreement and any other Loan Document are true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) on and as of the Amendment Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) as of such earlier date.

Each Loan Party hereby reaffirms its obligations under the Credit Agreement and each other Loan Document to which it is a party, in each case as amended by this Amendment and acknowledges and agrees that the grants of security interests by and the guarantees of the Loan Parties contained in the Loan Documents are, and shall remain, in full force and effect immediately after giving effect to this Amendment.

SECTION 6. <u>Execution in Counterparts; Electronic Signatures</u>. This Amendment may be executed by one or more of the parties to this Amendment on any number of separate counterparts (including by facsimile or other electronic imaging means), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of all of which is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. <u>Amendment to Credit Agreement</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The definition of "Maturity Date" in Section 1.01 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

""<u>Maturity Date</u>" means June 1, 2027."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Clause (o) of the definition of "Permitted Liens" in Section 1.01 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

"(o) Liens securing any and all Indebtedness permitted pursuant to clause (l) of the definition of Permitted Indebtedness;"

SECTION 2. <u>Representations and Warranties</u>. Each of the Loan Parties hereby represents and warrants on the Amendment Effective Date that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Loan Parties (i) is a corporation, limited liability company or limited partnership, as applicable, duly organized, validly existing and in good standing under the laws of the state or jurisdiction of its organization, (ii) has all requisite power and authority to conduct its business as now conducted and as presently contemplated and, in the case of the Borrower, to make the borrowings hereunder, and to execute and deliver this Amendment, and to consummate the transactions contemplated thereby, and (iii) is duly qualified to do business and is in good standing in each jurisdiction other than the state or jurisdiction of its organization in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary, except (solely for the purposes of this subclause (iii)) where the failure to be so qualified and in good standing could reasonably be expected to have a Material Adverse Effect. The Borrower and its Subsidiaries have obtained, and are in compliance with, all licenses, permits, approvals and other authorizations necessary for the operation of their business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The execution, delivery and performance by each Loan Party of this Amendment, (i) has been duly authorized by all necessary action, (ii) does not and will not contravene (A) any of its Governing Documents, (B) any applicable Requirement of Law or (C) any Contractual Obligation binding on or otherwise affecting it or any of its properties, (iii) does not and will not result in or require the creation of any Lien (other than pursuant to this Amendment) upon or with respect to any of its properties, except, in the case of clause (ii)(C), to the extent where such contravention, default, noncompliance, suspension, revocation, impairment, forfeiture or nonrenewal could not reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required in connection with the due execution, delivery and performance by any Loan Party of this Amendment other than any authorization, approval, notice or filing or other action as has been previously been obtained or taken and remains in full force and effect on the Amendment Effective Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Amendment is a legal, valid and binding obligation of each Loan Party, enforceable against each, such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and by general principles of equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of the Lender under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents.

Each Loan Party hereby reaffirms its obligations under the Credit Agreement and each other Loan Document to which it is a party, in each case as amended by this Amendment and acknowledges and agrees that the grants of security interests by and the guarantees of the Loan Parties contained in the Loan Documents are, and shall remain, in full force and effect immediately after giving effect to this Amendment.

SECTION 6. <u>Execution in Counterparts; Electronic Signatures</u>. This Amendment may be executed by one or more of the parties to this Amendment on any number of separate counterparts (including by facsimile or other electronic imaging means), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Amendment by facsimile or other electronic transmission (e.g. "pdf" or "tif" format) shall be effective as delivery of a manually executed counterpart hereof. The words "execution", "execute", "signed", "signature" and words of like import in or related to this Amendment or any other document to be signed in connection with this Amendment and the transactions contemplated hereby shall be deemed to include electronic signatures, the electronic matching of assignment terms and contract formations on electronic platforms approved by the Lender, or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; <u>provided</u> that notwithstanding anything contained herein to the contrary the Lender is under no obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Lender pursuant to procedures approved by it.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Loan Parties (i) is a corporation, limited liability company or limited partnership, as applicable, duly organized, validly existing and in good standing under the laws of the state or jurisdiction of its organization, (ii) has all requisite power and authority to conduct its business as now conducted and as presently contemplated and, in the case of the Borrower, to make the borrowings hereunder, and to execute and deliver this Amendment, and to consummate the transactions contemplated thereby, and (iii) is duly qualified to do business and is in good standing in each jurisdiction other than the state or jurisdiction of its organization in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary, except (solely for the purposes of this subclause (iii)) where the failure to be so qualified and in good standing could reasonably be expected to have a Material Adverse Effect. The Borrower and its Subsidiaries have obtained, and are in compliance with, all licenses, permits, approvals and other authorizations necessary for the operation of their business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Amendment is a legal, valid and binding obligation of each Loan Party, enforceable against each, such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and by general principles of equity.

**SECTION 6.** <u>Execution in Counterparts; Electronic Signatures</u>. This Amendment may be executed by one or more of the parties to this Amendment on any number of separate counterparts (including by facsimile or other electronic imaging means), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.
