The Loan Agreement provided for, among other things, a Revolving Facility with aggregate commitments of $9,000,000, which was increased to $15,000,000 by an amended and restated agreement dated December 21, 2018.

The Amended and Restated Loan Agreement requires the Company to maintain at least $3,000,000 in unrestricted cash at Heritage Bank. The Company was in compliance with all loan covenants under the Amended and Restated Loan Agreement as of the end of the current reporting period. Loans under the Revolving Facility bear interest at a rate equal to one half of one percentage point (0.50%) above the variable rate of interest, per annum, that appears in The Wall Street Journal from time to time, whether or not such announced rate is the lowest rate available from Heritage Bank.
