Guarantor and Bank propose to enter into a Pledge and Security Agreement dated on or about the date hereof (the “PSA”),
pursuant to which Guarantor shall cash secure a portion of its obligations under the Guaranty. Bank has agreed to enter into the
LSA Amendment and the PSA provided, among other things, that Guarantor agrees that the Guaranty, as modified by this Amendment
and Affirmation, will remain effective.

of Guarantor’s obligations under this Guaranty) of at least 1.00 times any Obligations owed by Borrower to Bank (excluding
any such Obligations which are cash-secured by cash held in segregated accounts at Bank in the name of the Guarantor).
