of not less than $500,000 until June 30, 2017. At all times after
June 30, 2017, the liquidity of the Company and its subsidiaries
must not be less than $5,000,000. The Amendment modified the
consolidated senior leverage ratio financial covenant of the

the Amendment waived any non-compliance with the covenant set
