Unless otherwise indicated, all section references in this Thirteenth Amendment refer to sections of the Credit Agreement.

1

Section 2.      Amendments. Subject to the Satisfaction of the Conditions Precedent in Section 6 of this Thirteenth Amendment, the following Amendments to the Credit Agreement shall be effective:

2.1            Amendment to Section 1.02. Section 1.02 is hereby amended by amending or adding the following defined terms in their entirety:

“Agreement” means this Amended, Restated and Consolidated Revolving Credit Agreement, including the Schedules and Exhibits hereto, as amended by that certain First Amendment dated as of April 18, 2019, that certain Second Amendment dated as of June 28, 2019, that certain Third Amendment dated as of November 13, 2019, that certain Fourth Amendment dated as of January 9, 2020, that certain Fifth Amendment dated as of January 22, 2020, that certain Sixth Amendment dated as of March 24, 2020, that certain Seventh Amendment dated as of May 21, 2020, that certain Eighth Amendment dated as of June 26, 2020, that certain Ninth Amendment dated as of November 19, 2020, that certain Tenth Amendment dated as of April 6, 2021, that certain Eleventh Amendment dated as of May 11, 2021, that certain Twelfth Amendment dated as of August 17, 2021, that certain Thirteenth Amendment dated as of December 7, 2021, and as the same may be further amended, modified, supplemented, restated, replaced or otherwise modified from time to time.

For purposes hereof, the date of a Borrowing initially shall be the date on which such Borrowing is made and thereafter shall be the effective date of the most recent conversion or continuation of such Borrowing.

Section 3.      Waivers.

3.1            Distribution. The Borrower has informed the Administrative Agent that it will not be able to comply with the Liquidity requirement of Section 9.04(a)(iv) for its December 2021 dividend distribution and has requested that the Administrative Agent and the Majority Lenders waive the requirement of Section 9.04(a)(iv) with respect to such December 2021 dividend distribution announced on August 5, 2021 (the “December 2021 Dividend Waiver”).

2

3.2            Investment in Tapstone. Section 9.05 does not permit an Investment in Equity Interests of another Person. Pursuant to the terms of the Tapstone Acquisition, the Borrower will be acquiring the Equity Interests in Tapstone and its subsidiaries. The Borrower has requested that the Administrative Agent and the Majority Lenders waive the provisions of Section 9.05 for the purposes of the Tapstone Acquisition (the “Investment Waiver”).

3.3            Merger. Section 9.10 does not permit a merger among Loan Parties where a Loan Party is not the surviving entity. Pursuant to the Tapstone Merger Agreement, Tapstone will be merged with a Guarantor and will be the surviving entity in connection with the Tapstone Acquisition. The Borrower has requested that the Administrative Agent and the Majority Lenders waive the provisions of Section 9.10 for the purposes of the Tapstone Acquisition (the “Merger Waiver”).

3.4            Waiver Approval. The Administrative Agent and the Lenders signatory hereto hereby consent to the December 2021 Dividend Waiver, the Investment Waiver and the Merger Waiver.

Section 4.      Borrowing Base. From and after the Thirteenth Amendment Effective Date until the next Scheduled Redetermination, the Borrowing Base shall be $825.0 million. The Borrowing Base may be subject to further adjustment from time to time in accordance with the Credit Agreement. Such Borrowing Base constitutes the Scheduled Redetermination for November 1, 2021.

Section 5.      Assignments and Reallocations. For an agreed consideration, the existing Lenders (the “Existing Lenders”) have agreed among themselves to reassign among themselves portions of their Commitments, Maximum Credit Amounts, Applicable Percentages and Revolving Credit Exposures and to allow Morgan Stanley Bank, N.A. (the “Exiting Lender”) to assign all of its Commitments, Maximum Credit Amounts, Applicable Percentages and Revolving Credit Exposures such that after such reassignments and assignment the Applicable Percentages and Maximum Credit Amounts of each Lender on the Thirteenth Amendment Effective Date shall be as set forth in Annex I attached hereto. Each of the Administrative Agent and the Borrower hereby consents to (a) such reassignments by the Existing Lenders of their Commitments, Maximum Credit Amounts, Applicable Percentages and Revolving Credit Exposures and (b) the Exiting Lender’s assignment of its interests in the Commitments, Maximum Credit Amounts, Applicable Percentages and Revolving Credit Exposures. The reassignments by the Existing Lenders and the assignment by the Exiting Lender necessary to effect the reallocation of the Commitments, Maximum Credit Amounts, Applicable Percentages and Revolving Credit Exposures are hereby consummated pursuant to the terms and provisions of this Thirteenth Amendment and Section 12.04(b), and the Borrower, the Administrative Agent, the Existing Lenders, and the Exiting Lender, hereby consummate such assignment and assumption pursuant to the terms, provisions and representations of the Assignment and Assumption attached as Exhibit G to the Credit Agreement as if each of them had executed and delivered an Assignment and Assumption with the Effective Date (as defined therein) being the Thirteenth Amendment Effective Date; provided that the Administrative Agent hereby waives the $3,500 processing and recordation fee set forth in Section 12.04(b)(ii)(C) with respect to such assignment and assumption. Annex I attached to the Credit Agreement is hereby deleted in its entirety and replaced by Annex I attached hereto.
