AMR entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan is twenty-one years. For the first twelve months only interest was payable; thereafter monthly payments of interest and principal are due. The interest rate adjusts on the first day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime lending rate charged by large U.S. money center commercial banks as published in the Wall Street Journal. The terms of the Loan Agreement contain various affirmative and negative covenants. Among them, AMR must maintain a minimum debt service coverage ratio of 1.25 to 1.0 (beginning with the twelve-month period ending March 31, 2017), a maximum debt-to-net worth ratio of 1.0 to 1.0 and a minimum current ratio of 1.5 to 1.0. AMR was in compliance with all covenants as of and for the years ending December 31, 2016 and 2015. AMR was in compliance with all but the minimum debt service coverage ratio covenant as of and for each of the three-month periods ended March 31, June 30, September 30 and December 31, 2017. AMR has received a waiver for the minimum debt service coverage ratio covenant for each of the three-month periods ended March 31, June 30, September 30 and December 31, 2017.

The net proceeds of the loan was deposited into an escrow account at Green Bank.

Collateral for this loan is AMR’s accounts receivable, goods, equipment, fixtures, inventory, accessions and a certificate of deposit in the amount of $1,000,000.
