This First Amendment to Loan and Security Agreement (this “Amendment”) is made and entered into as of July 8, 2020, by and

RECITALS 
 Borrower and Bank are
parties to that certain Loan and Security Agreement dated as of April 28, 2020 (as amended from time to time, the “Agreement”). The parties desire to amend the Agreement in accordance with the terms of this Amendment.

	1)	 A new Section 2.1(c) is hereby added to the Agreement, as follows: 

(c)    Usage of Credit Card Services Under the Credit Card Line. 

(i)    Usage Period. Subject to and upon the terms and conditions of this Agreement, at any
time from the First Amendment Effective Date through the Credit Card Maturity Date, Borrower may use the Credit Card Services (as defined below) in amounts and upon terms as provided in Section 2.1(c)(ii) below. 

(ii)    Credit Card Services. Subject to and upon the terms and conditions of this
Agreement, Borrower may request corporate credit cards and standard and e-commerce merchant account services from Bank (collectively, the “Credit Card Services”). The aggregate limit of the corporate
credit cards and merchant credit card processing reserves shall not exceed the Credit Card Line. The terms and conditions (including repayment and fees) of such Credit Card Services shall be subject to the terms and conditions of Bank’s
standard forms of application and agreement for the Credit Card Services, which Borrower hereby agrees to execute. 

(iii)    Collateralization of Obligations Extending Beyond Maturity. Borrower shall take
such actions as Bank may request to cause its obligations with respect to any Credit Card Services to be secured to Bank’s satisfaction as of the Credit Card Maturity Date. If Borrower has not cash secured its obligations with respect to any
Credit Card Services by the Credit Card Maturity Date, then, effective as of such date, the balance in any of Borrower’s deposit accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s
name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or
outstanding Credit Card Services. Borrower authorizes Bank to hold such balances in pledge and to decline to honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long
as the applicable Credit Card Services are outstanding or continue.
