(“Citizens”) pursuant to a Credit and Security Agreement by and among the Company, certain affiliates thereof as borrowers or guarantors, and Citizens (the “Credit Agreement”). On January 28, 2016, the Company entered into a Second Amendment to Credit and Security Agreement with Citizens and certain subsidiary affiliates of the Company as borrowers and/or guarantors (the “Amendment”). The Amendment amends the Credit Agreement and provides for an increase in the Company’s line of credit (the “Line of Credit”) with Citizens from $10.0 million to $20.0 million. The Line of Credit is secured by substantially all of the Company’s personal property, including the Company’s intellectual property and that of its subsidiaries that are borrowers or guarantors. The interest rate applicable to committed borrowings is tied to LIBOR plus a margin of 2.5%. The Credit Agreement also provides for a letter of credit sub-facility of up to $2.0 million. The Credit Agreement contains customary affirmative and negative covenants, including, among others, financial covenants based on the Company’s leverage and fixed charge coverage ratios, as well as an obligation to maintain a minimum availability requirement of at least $5.0 million in the aggregate of cash and availability under the line of credit. The Credit Facility will provide funds for general corporate purposes and repurchases of issued and outstanding capital stock of the Company. The Credit Facility matures on December 31, 2020 and is payable in full upon maturity. As of March 31, 2016, the Company was in compliance with all financial covenants contained in the Credit Agreement and no amounts were outstanding. On April 12, 2016, the Company borrowed approximately $13.9 million under the Credit Facility to repurchase approximately 3.9 million shares of common stock as part of the modified “Dutch auction” tender offer. Subsequently, on April 26, 2016, the Company repaid $4.0 million on the Credit Facility.
