RECITALS

A.    The Parent, Borrowers, Lenders, and Administrative Agent executed an Amended and Restated Credit Agreement dated as of April 25, 2017. as amended by First Amendment to Amended and Restated Credit Agreement dated as of January 16. 2018 (the “Credit Agreement”). Capitalized terms used herein and not otherwise defined herein will have the meanings defined in the Credit Agreement.

B.    The Borrower desires (i) to increase the Revolving Commitments from an aggregate of $200,000,000 to an aggregate of $250,000,000 and (ii) to reinstate the right to obtain a further increase of the Revolving Commitments up to an aggregate of $50,000,000 pursuant to Section 2.09 of the Credit Agreement.

NOW, THEREFORE. in consideration of their mutual covenants and undertakings the parties agree as follows:

I. AMENDMENTS TO CREDIT AGREEMENT

1.    Section 2.01 of the Credit Agreement is hereby amended to substitute $250,000,000 for $200,000,000 as the aggregate amount of the Revolving Commitments, including the previous increase of $50,000,000 pursuant to the First Amendment to the Credit Agreement.

2.    Schedule I (Commitment Schedule) attached to this Amendment hereby replaces Schedule 1 to the Credit Agreement; the revised Revolving Commitment and Applicable Percentage of each Lender shall be the amount and percentage set forth for such Lender on Schedule 1 hereof.

3.    Section 2.09(e) of the Credit Agreement is hereby amended to substitute $300,000,000 for $200,000,000 so as to provide for an increase of the aggregate Revolving Commitments from $250,000,000 to $300,000,000 on the terms and conditions in Section 2.09(e) through (h) of the Credit Agreement.

4.    Section 2.09(g) of the Credit Agreement is hereby amended to substitute $300,000,000 for $200,000,000.

II. MISCELLANEOUS

1.    This Amendment shall be effective upon the Administrative Agent’s receipt of (i) the fully executed counterparts of this Agreement, (ii) the fully executed Acknowledgment of Guarantors by the Parent and Subsidiary Guarantors and (iii) the fully executed Certificates for each Loan Party.

2.    Inasmuch as the Applicable Percentage for each Lender is changing, the Lenders who have lesser Applicable Percentages will be deemed to have assigned the difference to the Lenders who have greater Applicable Percentages, without the necessity of complying with the assignment provisions of the Credit Agreement.

3.    Borrower shall execute a new Revolving Loan Note (the “June 2018 Note”) for each Lender in the principal amount of such Lender’s new Applicable Percentage. These notes shall supersede and replace the Revolving Loan Note to such Lender dated January 16, 2018 (the “January 2018 Note”). Each June 2018 Note shall supersede and replace the corresponding January 2018 Note, which January 2018 Note shall be null and void.

4.    Simultaneously with the full execution of this Amendment, Borrower shall pay to the Administrative Agent for the benefit of the Lenders a one-time upfront fee of $75,000 (being 0.15% of the $50 million increase in the aggregate Revolving Commitments), payable pro rata to the Lenders on the basis of their final allocated participation in such increase.

5.    This Amendment shall be governed by and construed in accordance with the internal laws (and not the conflict of laws) of the State of Louisiana, but giving effect to federal laws applicable to national banks.

6.    This Amendment may be executed in counterparts (and by different parties hereto on different counterparts) each of which shall constitute an original but all of which taken together shall constitute a single Agreement.
