(45%) of gross availability and (ii) Ten Million Dollars ($10,000,000); in each case as determined by Bank from Borrower’s most recent Transaction Report; provided, however, that Bank has the right to decrease the

hereby represents and warrants to Bank as follows: 
 4.1 Immediately after giving effect to this Amendment (a) the

about the subject matter of this Amendment and the Loan Documents merge into this Amendment and the Loan Documents.
