Unless otherwise defined herein, capitalized terms that are defined in the Credit Agreement are used herein as defined therein.

WHEREAS, this Amendment includes amendments of the Credit Agreement that, in each case, will become effective on the Amendment Effective Date on the terms and subject to the conditions set forth herein.

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

Section 1. Amendment. Each of the parties hereto agrees that, effective on the Amendment Effective Date, the Credit Agreement shall be amended as follows:

(a) The following definitions are added in the appropriate alphabetical order to Section 1.01 of the Credit Agreement:

“Extension Effective Date” has the meaning specified in Section 2.15(e).

“First Amendment” means the First Amendment, dated as of May 1, 2019, among the Borrower, the Lenders party thereto and the Lead Administrative Agent.

“First Amendment Effective Date” means May 1, 2019.

(b) The following definitions in Section 1.01 of the Credit Agreement shall be amended and restated to read in their entirety as follows:

“Capital Lease” means any lease of property, real, personal or mixed, the obligations of the lessee in respect of which are required in accordance with GAAP to be classified and accounted for as a capital lease or a financing lease on a balance sheet of the lessee; provided, that all leases of any Person that are or would be characterized as operating leases in accordance with GAAP on the Closing Date (whether or not such operating leases were in effect on such date) shall continue to be accounted for as operating

leases (and not Capital Leases) for purposes of this Agreement, regardless of any change in GAAP following the Closing Date (or any change in the implementation in GAAP for future periods that are contemplated as of the First Amendment Effective Date) that would otherwise require such leases to be recharacterized as Capital Leases.

“Loan Documents” means this Agreement, the First Amendment, each Note, each Issuer Document, any agreement creating or perfecting rights in Cash Collateral pursuant to the provisions of Section 2.17 of this Agreement and the Fee Letters.

“Maturity Date” means March 29, 2024; provided that if maturity is extended pursuant to Section 2.15, the “Maturity Date” shall mean such maturity date as determined pursuant to such Section; provided, however, that, in each case, if such date is not a Business Day, the Maturity Date shall be the immediately preceding Business Day.

If (and only if) the total of the Commitments of the Lenders that have agreed so to extend their Maturity Date (each, an “Extending Lender”) and the assigned Commitments of the Additional Commitment Lenders shall be more than 50% of the aggregate amount of the Commitments in effect immediately prior to the then current Maturity Date, then, effective as of the effective date of the applicable extension agreement or amendment, in each case, in form and substance reasonably acceptable to the Lead Administrative Agent (each such date, an “Extension Effective Date”), the Maturity Date of each Extending Lender and of each Additional Commitment Lender shall be extended to the date falling one year after such Extension Effective Date (except that, if such date is not a Business Day, such Maturity Date as so extended shall be the immediately preceding Business Day) and each Additional Commitment Lender shall thereupon become a “Lender” for all purposes of this Agreement. ”

(d) Section 2.15(f) of the Credit Agreement shall be amended and restated to read in its entirety as follows:

“ (f) Conditions to Effectiveness of Extensions. As a condition precedent to such extension, the Borrower shall deliver to the Lead Administrative Agent a certificate dated as of the applicable Extension Effective Date signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension and (ii) certifying that, before and after giving effect to such extension, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct in all material respects (except to the extent that any representation and warranty is otherwise qualified by materiality, in which case such representation and warranty shall be true and correct in all respects) on and as of such applicable Extension Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.15, the representations and warranties contained in subsections (a) and (b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to subsections (a) and (b), respectively, of Section 6.01, and (B) no Default exists. In addition, on the Maturity Date of each Non-Extending Lender, the Borrowers shall repay in full all Obligations (other than contingent indemnification obligations and Letters of Credit issued by any Non-Extending Lender that

constitutes an L/C Issuer that have been Cash Collateralized or as to which other arrangements satisfactory to such Non-Extending Lender have been made), including any Committed Loans outstanding on such date (and pay any additional amounts required pursuant to Section 3.05) (which prepayment may, notwithstanding any pro rata borrowing requirements set forth in this Agreement, be effected through a Committed Borrowing funded by the Lenders other than the Non-Extending Lenders) to the extent necessary to keep outstanding Committed Loans ratable with any revised Applicable Percentages of the respective Lenders effective as of such date. ”

(e) Section 7.05 of the Credit Agreement shall be amended by replacing the number “$150,000,000” in the proviso in clause (k) thereof with the number “$250,000,000”.
