 RECITALS: 

WHEREAS, the Borrowers have requested that, pursuant to Section 2.25 and

amount of $130,500,000 (the “2021 Revolving Commitment Increase”). The individual 2021 Revolving Commitment Increase for each such 2021 Incremental Revolving Lender shall be as set forth in Schedule I attached. 

WHEREAS, each 2021 Incremental Revolving Lender has agreed, on the terms and conditions set forth herein, to provide such 2021 Revolving
Commitment Increase and to become, if not already, a Lender for all purposes under the Credit Agreement. 
 WHEREAS, the Borrowers have
requested that, pursuant to Section 2.26 and Section 11.1(b)(v) of the Existing Credit Agreement, concurrently with the effectiveness of the 2021 Revolving Commitment Increase, each 2021 Other
Revolving Lender extend Other Revolving Commitments (the “2021 Other Revolving Commitments”) on the IPO Effective Date, which 2021 Other Revolving Commitments will refinance in full all Revolving Commitments outstanding under the
Existing Credit Agreement. 
 WHEREAS, the Existing Credit Agreement may be amended to (i) give effect to provisions of
Section 2.25 of the Credit Agreement through an Incremental Amendment executed by the Borrowers, the Administrative Agent and each 2021 Incremental Revolving Lender providing a 2021 Revolving Commitment Increase and
(ii) give effect to the provisions of Section 2.26 of the Credit Agreement through a Refinancing Amendment executed by the Borrowers, the Administrative Agent, the Issuing Lenders and each 2021 Other Revolving Lender
providing a 2021 Other Revolving Commitment. 
  












 WHEREAS, each Letter of Credit issued and outstanding on the IPO Effective Date (as defined
below), if any, shall be deemed to be a Letter of Credit pursuant to the Revolving Facility in effect on and after the IPO Effective Date. 

NOW THEREFORE, the parties hereto therefore agree as follows: 

SECTION 1. Defined Terms. Unless otherwise specifically defined herein, each term used herein that is defined in the Credit
Agreement has the meaning assigned to such term in the Credit Agreement. 
 SECTION 2. 2021 Revolving Commitment Increase.

 (a) Subject to and upon the terms and conditions set forth herein, after the Amendment No. 3 Effective Date has occurred, upon
(i) delivery to the Administrative Agent of an Officer’s Certificate not later than 12:00 noon (New York City time) on the IPO Effective Date (as defined below) (or such later time as the Administrative Agent may reasonably agree) stating
that a Public Offering has occurred and certifying to the Administrative Agent that as of the date thereof, no Default or Event of Default exists under the Credit Agreement (the date such Officer’s Certificate is delivered, the “IPO
Effective Date”) and (ii) receipt by the 2021 Revolving Lenders of all fees required to be paid on or prior to the IPO Effective Date and all reasonable and documented
out-of-pocket expenses for which reasonably detailed invoices have been presented to the Borrower Representative at least three (3) Business Days prior to the IPO
Effective Date (or such later date as the Borrower Representative may reasonably agree), each 2021 Incremental Revolving Lender agrees (on a several and not joint basis) to make their respective 2021 Revolving Commitment Increase available to the
Borrowers, effective on receipt of such Officer’s Certificate and payment of such fees and expenses. The aggregate amount of all the Revolving Commitments on the IPO Effective Date (after giving effect to the 2021 Revolving Commitment Increase
and the 2021 Revolving Refinancing set forth in Section 3 (collectively, the “New Revolving Commitments”)) shall be $289,000,000. 

(b) This Amendment constitutes an “Incremental Amendment” with respect to the establishment of the 2021 Revolving Commitment Increase
as a “Revolving Commitment Increase”. The 2021 Revolving Commitment Increase is being established in accordance with Section 2.25 of the Existing Credit Agreement. Each of the 2021 Incremental Revolving Lenders
constitutes an Incremental Revolving Lender pursuant to Section 2.25 of the Credit Agreement and, in such capacity, acknowledges the provisions of Section 2.25 of the Existing Credit Agreement. For the avoidance
of doubt, commitments and loans made pursuant to the 2021 Revolving Commitment Increase shall be “Revolving Commitments”, “Revolving Loans” and “Loans” for all purposes under the Credit Agreement and each other Loan
Document and shall be treated as the same Class and Facility as the Revolving Commitments and Revolving Loans established pursuant to Section 3 below. Any revolving loans and other extensions of credit made pursuant to the 2021 Revolving
Commitment Increase shall have terms identical to the Revolving Commitments and Revolving Loans established pursuant to Section 3 below and shall rank pari passu in right of payment and security with such Revolving Commitments. The
Borrowers and the 2021 Incremental Revolving Lenders hereby authorize the Administrative Agent to update the Register to reflect the amount, terms and date of the 2021 Revolving Commitment Increase and the identity of the 2021 Incremental Revolving
Lenders. 
 (c) Notwithstanding the foregoing, if the IPO Effective Date does not occur prior to September 30, 2021, the 2021 Revolving
Commitment Increase shall be terminated automatically without becoming effective and this Section 2 shall have no effect. 
 SECTION
3. 2021 Revolving Refinancing; New Revolving Commitments. 

  
 2 













 (a) Subject to and upon the terms and conditions set forth herein, after the Amendment
No. 3 Effective Date has occurred, concurrently with the effectiveness of 2021 Revolving Commitment Increase, on the IPO Effective Date: 

(i) each 2021 Other Revolving Lender agrees (on a several and not joint basis) to make their respective 2021 Other Revolving
Commitments available to the Borrowers, and the individual 2021 Other Revolving Commitments for each Lender shall be as set forth in Schedule I attached; 

(ii) each 2021 Other Revolving Lender that is not an Issuing Lender agrees that it will become an Issuing Lender; 

(iii) all Revolving Commitments under the Existing Credit Agreement shall be terminated and replaced with the 2021 Other
Revolving Commitments; 
 (iv) the aggregate amount of all the New Revolving Commitments shall be 

$289,000,000; 

(v) the portion of Schedule 1.1A-1 of the Existing Credit Agreement appearing under the
heading “Revolving Commitments” shall be replaced by Schedule I attached hereto; 
 (vi) Schedule 1.1A-2 of the Existing Credit Agreement shall be replaced by Schedule II attached hereto; and 

(vii) Section 1.1 of the Existing Credit Agreement shall be amended by amending and restating the definition of
“Revolving Termination Date” set forth therein with the following: 
 “Revolving Termination Date”: May 2,
2025. 
 (b) This Amendment constitutes a “Refinancing Amendment” with respect to the establishment of the 2021 Other Revolving
Commitments as “Other Revolving Commitments”. The 2021 Other Revolving Commitments are being established in accordance with Section 2.26 of the Existing Credit Agreement. Each of the 2021 Other Revolving Lenders
acknowledges the provisions of Section 2.26 of the Existing Credit Agreement. For the avoidance of doubt, commitments and loans made pursuant to the 2021 Other Revolving Commitments shall be “Revolving
Commitments”, “Revolving Loans” and “Loans” for all purposes under the Credit Agreement and each other Loan Document. The Borrowers and the 2021 Other Revolving Lenders hereby authorize the Administrative Agent to update the
Register to reflect the amount, terms and date of the 2021 Other Revolving Commitments and the identity of the 2021 Other Revolving Lenders. 

(c) Notwithstanding the foregoing, if the IPO Effective Date does not occur prior to September 30, 2021, the 2021 Other Revolving
Commitments shall be terminated without becoming effective and this Section 3 shall have no effect. 
 SECTION 4. Amendments

parties hereto agree that on the Amendment No. 3 Effective Date, the Credit Agreement shall be amended as follows:

 SECTION 12. Credit Agreement Governs. Except as expressly set forth herein,
this Amendment shall not by implication or otherwise limit, impair, constitute a waiver of or otherwise affect the rights and remedies of any Lender, the Administrative Agent or the Collateral Agent under the Credit Agreement or any other Loan

This Amendment and any document, amendment, approval, consent, information, notice, certificate, request, statement, disclosure or authorization related to this Amendment (each a “Communication”), including Communications
required to be in writing, may be in the form of an Electronic Record and may be executed using Electronic Signatures. Each of the parties hereto agrees that any Electronic Signature on or associated with any Communication shall be valid and binding
on each such Person to the same extent as a manual, original signature, and that any Communication entered into by Electronic Signature, will constitute the legal, valid and binding obligation of each such Person enforceable against such Person in
accordance with the terms hereof or thereof, as applicable, to the same extent as if a manually executed original signature was delivered. Any Communication may be executed in as many counterparts as necessary or convenient, including both paper and
electronic counterparts, but all such counterparts are one and the same Communication. For the avoidance of doubt, the authorization under this paragraph may include use or acceptance by any party hereto of a manually signed paper Communication
which has been converted into electronic form (such as scanned into PDF format), or an electronically signed Communication converted into another format, for transmission, delivery and/or retention. All Communications in the form of an Electronic
Record, including an Electronic Copy, shall be considered an original for all purposes, and shall have the same legal effect, validity and enforceability as a paper record. Without limiting the foregoing, (a) each party hereto shall be entitled
to rely on any such Electronic Signature purportedly given by or on behalf of any other party hereto without further verification and (b) upon the reasonable request of any party hereto, any Electronic Signature shall be promptly followed by a
manually executed counterpart. For purposes hereof, “Electronic Record” and “Electronic Signature” shall have the meanings assigned to them, respectively, by 15 USC §7006, as it may be amended from time to time. 

SECTION 14. Miscellaneous. This Amendment shall constitute an “Incremental Amendment”, “Refinancing
Amendment” and a “Loan Document” for all purposes of the Credit Agreement and the other Loan Documents. The provisions of this Amendment are deemed incorporated into the Credit Agreement as if fully set forth therein. The headings of
this Amendment are for the purposes of reference only and shall not limit or otherwise affect the meaning hereof. Section 11.14 of the Credit Agreement is incorporated by reference herein, mutatis mutandis. 

SECTION 15. Severability. Any provision of this Amendment that is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating 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.
