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

SECTION 1.    Definitions. Capitalized terms not otherwise defined in this First Amendment have the same meanings as specified in the Credit Agreement.

SECTION 2.    2020 Incremental Revolving Commitments.

(a)    Each Incremental Lender hereby severally agrees to provide a 2020 Incremental Revolving Commitment to the Borrower effective as of the First Amendment Effective Date in the principal amount set forth opposite such Incremental Lender’s name on the 2020 Incremental Revolving Commitment Schedule (as defined below) and which, collectively, shall be a sum equal to an aggregate principal amount of $25,000,000. On and after the First Amendment Effective Date, the 2020 Incremental Revolving Commitments provided pursuant to this First Amendment shall be added to (and thereupon constitute) “Initial Revolving Commitments” and “Revolving Commitments” under the Credit Agreement for all purposes therein and in the other Loan Documents and shall be subject to all of the same terms and conditions set forth in the Credit Agreement with respect to the Initial Revolving Commitments and Revolving Commitments (each as amended hereby). The Incremental Lenders, the Borrower, the Administrative Agent, the Collateral Agent, the Revolving Agent and the other Revolving Lenders agree that the 2020 Incremental Revolving Commitments are (i) subject to the same terms as the Initial Revolving Commitments, as amended by this First Amendment, (ii) guaranteed by the Guarantors, and (iii) secured on an equal priority basis by the same Collateral securing, in each case, the existing Revolving Commitments under the Credit Agreement as in effect immediately prior the effectiveness of this First Amendment.

(b)    Each Incremental Lender (i) agrees that it will, independently and without reliance upon the Administrative Agent, the Collateral Agent, the Revolving Agent or any other Revolving Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement (as amended by this First

Amendment), the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; (ii) appoints and authorizes the Administrative Agent, the Revolving Agent and the Collateral Agent to take such actions as agent on its behalf and to exercise such powers and discretion under the Credit Agreement (as amended by this First Amendment), the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto as are delegated to the Administrative Agent, the Revolving Agent and the Collateral Agent, respectively, by the terms thereof, together with such powers as are incidental thereto; and (iii) agrees that it will be bound by the provisions of the Credit Agreement (as amended by this First Amendment) and will perform in accordance with its terms all the obligations which by the terms of the Credit Agreement (as amended by this First Amendment) are required to be performed by it as a Lender.

(c)    Upon the occurrence of the First Amendment Effective Date, (i) each Lender with a Revolving Commitment under the Credit Agreement as in effect immediately prior to the effectiveness of this First Amendment (each, an “Existing Lender”) will automatically and without further action be deemed to have assigned to each Incremental Lender in respect of the 2020 Incremental Revolving Commitments, and each such Incremental Lender will automatically and without further action be deemed to have assumed, a portion of such Existing Lender’s participations under the Loan Documents in outstanding Swing Line Loans and Letters of Credit such that, after giving effect to each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding participations under the Loan Documents in Swing Line Loans and Letters of Credit held by such Incremental Lender in respect of its 2020 Incremental Revolving Commitments will equal the percentage of the aggregate Revolving Commitments of all Lenders represented by such Incremental Lender’s 2020 Incremental Revolving Commitments (with such existing participation in such Swing Line Loans and Letters of Credits by Existing Lenders to be assigned on a pro rata basis to such Incremental Lenders determined on a Swing Line Loans and Letter of Credit by Swing Line Loans and Letter of Credit basis) and (ii) if, on such date, there are any Revolving Loans outstanding, each of the Existing Lenders shall be deemed to assign to each of the Incremental Lenders, and each of the Incremental Lenders shall purchase from each of the Existing Lenders, at par, such interests in the Revolving Loans outstanding on such date as shall be necessary in order that, after giving effect to all such assignments and purchases, the percentage of the aggregate Revolving Loans held by each Incremental Lender in respect of its 2020 Incremental Revolving Commitment will equal the percentage of the aggregate Revolving Commitments of all Lenders represented by such Incremental Lender’s 2020 Incremental Revolving Commitment (with such assignments to be made on a pro rata basis to such Incremental Lenders determined on a Revolving Loan by Revolving Loan basis) and, in connection with the foregoing clauses (i) and (ii) the Existing Lenders and the Incremental Lenders will make adjustments among themselves, and payments to each other as needed, with respect to participations under the Loan Documents in outstanding Swing Line Loans and Letters of Credit, outstanding Revolving Loans and interest, commitment fees and other amounts paid or payable with respect thereto as shall be necessary, in the opinion of the Revolving Agent, in order to effect the foregoing; provided that regularly accruing interest and fees through the Effective Date (as well as amounts owing to any Lender pursuant to Sections 2.11, 2.12, 3.01, 4.04 and 11.06 of the Credit Agreement or similar provisions pursuant to the other Loan Documents) shall be retained by the respective Lenders to which such amounts were owing and shall not be subject to the assignments sold and purchased as otherwise required hereby.

(d)    From and after the First Amendment Effective Date, each Incremental Lender (i) shall be obligated to provide its 2020 Incremental Revolving Commitments as provided in this First Amendment on the terms, and subject to the conditions, set forth in the Credit Agreement (as amended nu this First Amendment) and (ii) to the extent provided in this First Amendment, shall have the rights and obligations of a Revolving Lender and a Lender under the Credit Agreement (as amended by this First Amendment) and under the other applicable Loan Documents.

(e)    The Revolving Agent has prepared a schedule attached hereto as Annex I (the “2020 Incremental Revolving Commitment Schedule”), which sets forth the 2020 Incremental Revolving Commitments of each of the Incremental Lenders. Each Incremental Lender is a signatory to this First Amendment and shall constitute a Lender under, and as defined in, the Credit Agreement (as amended by this First Amendment).
