Restricted Cash

On March 28, 2013, the Company and Comerica mutually agreed to amend the Comerica Loan Agreement (the "Amendment"), see Note 4. The Amendment established revised definitions and ratios relating to certain financial covenants to reflect the Company's projections of EBITDA and liquidity. The Amendment also provided that the Company maintain a minimum cash balance of $400,000 in our accounts at Comerica Bank and limit extraordinary expenses in connection with acquisitions.

The letter of credit for our corporate headquarters (as discussed in Note 10) for $57,000 is secured by $57,000 of cash pledged as collateral and is restricted by Comerica Bank.
