Attention: Robert G. Watson, Jr.

Dear Mr. Watson:

The purpose of this Letter Agreement is to set forth our mutual understanding as to certain deposits that will be maintained with Texas Capital Bank.

Pursuant to Section IX.B. of the Ninth Amendment, Parent and the other Borrowers are required to maintain with Texas Capital Bank certain proceeds derived from any Potential Issuance, as such term is defined in the Ninth Amendment. Parent and the other Borrowers have determined that an amount of up to $1,000,000 in the aggregate of such proceeds from any Potential Issuance or any other such issuances consummated prior to the date of this Letter Agreement must: (1) remain unencumbered by any Liens under the Loan Documents through and including November 1, 2015 and (2) request a waiver of the provisions under Section 7.06 of the Credit Agreement which prohibits Borrowers from making Restricted Payments under certain circumstances, including during the existence of an Event of Default, in each case, to allow Parent and/or the other Borrowers to declare and pay dividends that become due and payable under the equity interests issued under any Potential Issuance or any other such issuances consummated prior to the date of this Letter Agreement.
