Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to them in the Amended and Restated Credit Agreement (as hereinafter defined).

WHEREAS, each of the Debtors has reviewed, consented to and executed various “Collateral Documents” (as defined in the Prior Credit Agreement) in connection with the Prior Credit Agreement, as set forth on Exhibit A hereto (collectively, the “Existing Collateral Documents”);

WHEREAS, the Borrower, the Guarantors, the Administrative Agent and the Lenders have agreed to amend and restate the Prior Credit Agreement pursuant to that certain Amended and Restated Credit Agreement dated as of June 26, 2019 (as amended, supplemented, amended and restated or otherwise modified from time to time, the “Amended and Restated Credit Agreement”), without constituting a novation;

WHEREAS, each Debtor shall derive both direct and indirect additional benefits from the loans and other financial accommodations (collectively, the “Loans”) made pursuant to or otherwise evidenced or governed by the Amended and Restated Credit Agreement;

WHEREAS, it is a condition precedent to the effectiveness of the Amended and Restated Credit Agreement that each Debtor enter into this Master Reaffirmation to acknowledge and agree that the Existing Collateral Documents, and the liens, security interests and guarantees granted and issued thereunder, secure and guaranty the Obligations, Hedging Liability, and Bank Product Obligations;

NOW, THEREFORE, in consideration of the premises set forth herein and to induce the Lenders to make the Loans pursuant to the Amended and Restated Credit Agreement, and to enter into and perform obligations under the Amended and Restated Credit Agreement and for other good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged, each of the undersigned hereby agrees as follows:

1.02. Schedules A through F of the Security Agreement are hereby amended by deleting such schedules in their entirety and substituting therefor the replacement schedules attached hereto as Exhibit B (such amended and substituted schedules, the “Amended Security Agreement Schedules”).

SECTION 2. REAFFIRMATION.

Each Debtor, as debtors, grantors, pledgors, guarantors, mortgagors, assignors, as applicable, or in other similar capacities in which any such Debtor grants liens or security interests in its properties or otherwise act as accommodation parties or guarantors, as the case may be, in any case under the Existing Collateral Documents, hereby ratifies and reaffirms all of its payment and performance obligations, contingent or otherwise, under each such Existing Collateral Document to which it is a party and, to the extent such Debtor granted liens on or security interests in any of its properties pursuant to any such Existing Collateral Documents as security for the Obligations under or with respect to the Prior Credit Agreement or the Amended and Restated Credit Agreement, any Hedging Liability and any Bank Product Obligations, each hereby ratifies and reaffirms such grant of liens and security interests and confirms and agrees that such liens and security interests hereafter secure all of the Obligations, Hedging Liability, and Bank Product Obligations, including, without limitation, all additional Obligations, Hedging Liability, and Bank Product Obligations resulting from the Amended and Restated Credit Agreement, in each case as if each reference in such Existing Collateral Documents to the obligations secured thereby are construed to hereafter mean and refer to such Obligations under the Amended and Restated Credit Agreement, any Hedging Liability and any Bank Product Obligations. Each Debtor hereby acknowledges receipt of a copy of the Amended and Restated Credit Agreement and hereby consents to the terms and conditions of the Amended and Restated Credit Agreement, subject to the limitations, if any, set forth therein, and each Debtor hereby acknowledges that each of the Existing Collateral Documents, as amended hereby, remains in

full force and effect and is hereby ratified and confirmed.
