 WHEREAS, the Borrower has given notice to the Administrative Agent and the Lenders that it is not in compliance with

 WHEREAS, the Lenders have agreed
to waive the Section 7.02 Default pursuant to and upon the terms and conditions of this Agreement (the “Waiver”). Consistent with the foregoing, nothing contained herein is intended or shall be deemed to constitute an
acknowledgment, representation, warranty, covenant, or other agreement on the part of the Lenders that they have agreed or they will agree (i) to enter into any amendment to the Credit Agreement and the other Loan Documents on any terms and
conditions other than as set forth herein or (ii) to any waiver relating to any Default or Event of Default other than the Section 7.02 Default. 
 NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the parties hereto agree as follows:

 3. REAFFIRMATION. All provisions of the Credit Agreement and the other Loan Documents shall continue in full force and effect in accordance with the provisions thereof, and the Borrower reaffirms
all its agreements under the Credit Agreement and the Loan Documents, notwithstanding the occurrence of the Section 7.02 Default. 







 4. CONDITIONS TO EFFECTIVENESS. This Agreement will be effective once this Agreement
shall have been executed and delivered by the Borrower, the Administrative Agent, and the Required Lenders. 
 5.
REPRESENTATIONS AND WARRANTIES. To induce the Lenders and the Administrative Agent to enter into this Agreement, the Borrower represents and warrants to the Administrative Agent and each Lender as follows: 

5.1 Due Authorization, Non-Contravention, etc. The execution, delivery and performance of this Agreement by the Borrower are
within its powers, have been duly authorized by all necessary action, and do not:

 (b) contravene any contractual restriction, law or governmental regulation or court
decree or order binding on or affecting the Borrower or any of its Subsidiaries; or 
 (c) result in, or require
the creation or imposition of, any Lien on any of the properties of the Borrower or any of its Subsidiaries. 
 5.2
Defaults. The Section 7.02 Default is the only Default or Event of Default that has occurred and is continuing. 

5.3 Credit Agreement Representations and Warranties. The representations and warranties set forth in Article VI of the Credit
Agreement are true and correct with the same effect as if made as of the date hereof (unless stated to relate solely to an earlier date, in which case such representations and warranties shall be true and correct as of such earlier date).

 5.4 Validity, etc. This Agreement constitutes the legal, valid and binding obligation of the Borrower enforceable
against the Borrower in accordance with its terms. 
 6. MISCELLANEOUS. 

6.1 Limited Waiver; Continuing Effectiveness, etc. This Agreement shall be strictly limited to its terms. In this Agreement, the
Lenders waive no Default or Event of Default, whether presently or subsequently existing except for the Section 7.02 Default. This Agreement shall be deemed to be an amendment to the Credit Agreement, and the Credit Agreement, as amended
hereby, shall remain in full force and effect and is hereby ratified, approved and confirmed in each and every respect. After the amendments set forth herein have become effective, all references to the Credit Agreement in the Loan Documents or in
any other document, instrument, agreement or writing shall be deemed to refer to the Credit Agreement as amended hereby. Each other Loan Document is hereby ratified, approved and confirmed in each and every respect. 

6.2 Payment of Costs and Expenses. The Borrower agrees to pay on demand all reasonable expenses of the Administrative Agent
(including the reasonable fees and out-of-pocket expenses of counsel to the Administrative Agent) in connection with the negotiation, preparation, execution and delivery of this Agreement and the transactions contemplated hereby.

be effective as delivery of a manually-executed counterpart hereof.
