dated February 20, 2018, as amended by that certain Second Amendment dated of even date, and as now or hereafter amended, restated, replaced, supplemented, or otherwise modified, from time to time (collectively the “Loan

 1. Guaranties. Each
of the Guarantors is legally obligated under an unlimited guaranty dated January 13, 2014, or September 3, 2015, executed by each of the respective Guarantors in favor of Lender in connection with the Loans to Borrower (each a
“Guaranty”, and collectively the “Guaranties”). 
 2. Ratification. Each of the Guarantors consents to the
Loan Agreement and the Revolving Loan in the maximum amount of $60,000,000.00, and ratifies and confirms their respective Guaranty, acknowledges that their Guaranty is valid, subsisting, and binding upon the respective Guarantors, and agrees that
their Guaranty guarantees payment of the Loans (including the Revolving Loan), and the Notes (including the Revolving Note) in accordance with the terms of the respective Guaranty. 

3. Notice of Final Agreement. As of the effective date of this Notice, Borrower, Guarantors, and Lender have consummated a transaction
pursuant to which Lender has agreed to make a loan or loans to Borrower, to renew and extend an existing loan or loans to Borrower, and to otherwise extend credit or make financial accommodations to or for the benefit of Borrower, in an aggregate
amount up to $60,000,000.00 (collectively, whether one or more, the “Loans”). 
 In connection with the Loans, Borrower and
Lender and the undersigned Guarantors have executed and delivered and may hereafter execute and deliver certain agreements, instruments, and documents (collectively hereinafter referred to as the “Written Loan Agreement”). 

It is the intention of Borrower, Lender, and Guarantors that this Notice be incorporated by reference into each of the written agreements,
instruments, and documents comprising the Written Loan Agreement. Borrower, Lender, and Guarantors each warrant and represent that the entire agreement made and existing by or among Borrower, Lender, and Guarantors with respect to the Loan is and
shall be contained within the Written Loan Agreement, as amended and supplemented hereby, and that no agreements or promises exist or shall exist by or among Borrower, Lender, and Guarantors that are not reflected in the Written Loan Agreement.
