Friendswood, Suite 201, Friendswood, TX 77546 (“Borrower”).


WHEREAS, Collateral Agent, Borrower and the Lenders party to the Loan Agreement from time to time have entered into that certain Loan and Security Agreement, dated as of November 30, 2018 (as amended, supplemented or otherwise modified from time to time, including, but without limitation, pursuant to that certain First Amendment to Loan and Security Agreement dated as of June 13, 2019, collectively, the “Loan Agreement”) pursuant to which the Lenders have provided to Borrower certain loans in accordance with the terms and conditions thereof; and


WHEREAS, an Event of Default has occurred and is continuing under Section 8.2(a) (Covenant Default) of the Loan Agreement as a result of a violation of Section 6.6(b) of the Loan Agreement resulting from Borrower’s maintaining over $[***] of cash in its [***] account for the periods from February 1, 2019 through January 31, 2020 (the “Existing Default”). By reason of the Existing Default, Collateral Agent has the right to accelerate the maturity of the unpaid balance of the Obligations. In addition, as a result of the foregoing Existing Default, Collateral Agent and the Lenders are entitled to exercise any and all default-related rights and remedies under the Loan Agreement, other Loan Documents and/or applicable Law.
WHEREAS, Borrower has requested that Collateral Agent and the Lenders waive the Existing Default; 
WHEREAS, although the Lenders and Collateral Agent are under no obligation to do so, the Lenders and
Collateral Agent have agreed to waive the Existing Default, but only to the extent, in accordance with the terms, subject to the conditions and in reliance upon the representations and warranties set forth below;


WHEREAS, Borrower, the Lenders and Collateral Agent also desire to amend certain provisions of the Loan Agreement, but only to the extent, in accordance with the terms, subject to the conditions and in reliance upon the representations and warranties set forth below;


NOW, THEREFORE, in consideration of the promises, covenants and agreements contained herein, and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Borrower, the Lenders and Collateral Agent hereby agree as follows:


		
	1.
	Capitalized terms used herein but not otherwise defined shall have the respective meanings given to them in the Loan Agreement.


		
	2.
	Borrower acknowledges and agrees that unless the Existing Default is waived by Collateral Agent and the Lenders, the Existing Default would constitute an Event of Default under the Loan Documents as of the date hereof. Collateral Agent and the Lenders hereby waive the Existing Default. Collateral Agent’s and the Lenders’ agreement to waive the Existing Default shall in no way obligate Collateral Agent or any Lender to make any other modifications to the Loan Agreement or to waive Borrower’s compliance with any other terms of the Loan Documents, and shall not limit or impair Collateral Agent’s and the Lenders’ right to demand strict performance of all other terms and covenants as of any date. The waiver set forth above shall not be deemed or otherwise construed to constitute a waiver of any other provisions of the Loan Agreement in connection with any other transaction

	f.
	This Amendment has been duly executed and delivered by Borrower and is the binding obligation of Borrower, enforceable against Borrower in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, liquidation, moratorium or other similar laws of general application and equitable principles relating to or affecting creditors’ rights.




		
	15.
	Except as expressly set forth herein, the Loan Agreement shall continue in full force and effect without alteration or amendment. This Amendment and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements.
