NOTE 8—LINES OF CREDIT AND OTHER BORROWINGS

Lines of Credit

During the year ended December 31, 2012, the Company entered into and amended two revolving credit facility agreements with Comerica Bank (the “Credit Agreements”), which provide for borrowings against certain domestic accounts receivable and inventory, as set forth in the $4.0 million revolving credit facility agreement (the “Domestic Revolver”), and borrowings against certain export related accounts receivable and inventory, as set forth in the $4.0 million revolving credit facility agreement (the “Ex-Im Revolver”), for a combined aggregate commitment of borrowings up to $8.0 million. On May 7, 2013, the Company amended the Credit Agreements (“Amendment No. 2”) with Comerica Bank to increase the borrowing capacity under the Domestic Revolver from $4.0 million to $6.0 million, resulting in a combined aggregate commitment of borrowings up to $10.0 million. The lines of credit mature on May 1, 2014, at which date any remaining borrowings and accrued interest under the lines of credit become due and payable. As of June 30, 2013, the Company had aggregate outstanding borrowings totaling approximately $6.0 million, which included $3.2 million under the Domestic Revolver and $2.8 million under the Ex-Im Revolver, as compared with aggregate outstanding borrowings totaling approximately $1.6 million as of December 31, 2012.

Lockbox arrangements under the revolving bank facilities provide that substantially all of the income generated is deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of Comerica Bank. Cash is disbursed from Comerica Bank to the Company only after payment of the applicable debt service and principal. At June 30, 2013 and December 31, 2012, there were no restricted cash amounts. The Company’s obligations are generally secured by substantially all of the Company’s assets now owned or hereinafter acquired.

The Credit Agreements require the Company to maintain compliance with certain financial and non-financial covenants, as defined therein. If a default occurs, Comerica Bank may declare the amounts outstanding under the Credit Agreements immediately due and payable. As of June 30, 2013, the Company was in compliance with these covenants with the exception of the earnings before income tax, depreciation and amortization (“EBITDA”) covenant. On August 5, 2013, the Company obtained a waiver for noncompliance of the minimum EBITDA covenant from Comerica Bank as of June 30, 2013, provided that the Company and Comerica Bank establish amended covenants by September 13, 2013 and until the amendment is executed the aggregate borrowing capacity is reduced from $10.0 million to $7.5 million.

As a result of Amendment No. 2, interest rates on the outstanding principal balance of the Credit Agreements bear interest at annual percentage rates equal to the daily prime rate, plus 2.00% for the Domestic Revolver and 1.50% for the Ex-Im Revolver. The daily prime rate is subject to a floor of the daily adjusting LIBOR rate plus 2.50% per annum, or if LIBOR is undeterminable, 2.50% per annum. Prior to the amendment, interest rates were equal to the daily adjusting LIBOR rate (subject to a floor of 1.00% per annum), plus spreads of 5.25% for the Domestic Revolver and 4.25% for the Ex-Im Revolver. The Company is also required to pay an unused commitment fee of 0.25% based on a portion of the undrawn lines of credit, payable quarterly in arrears. During the three and six months ended June 30, 2013, the Company incurred interest expense associated with the credit facilities of $116,000 and $200,000, respectively, including $43,000 and $81,000 of amortization of deferred debt issuance costs and $18,000 and $36,000 of amortization of the discount on lines of credit, respectively. During the three and six months ended June 30, 2012, the Company incurred interest expense associated with the credit facilities of $38,000, including $15,000 of amortization of deferred debt issuance costs and $7,000 of amortization of the discount on lines of credit. Interest expense payable was approximately $26,000 and $19,000 at June 30, 2013 and December 31, 2012, respectively, and was included in accrued liabilities in the accompanying consolidated financial statements.

During the year ended December 31, 2012, the Company issued and amended a warrant to Comerica Bank (the “2012 Comerica Warrant”) to purchase up to 80,000 shares of the Company’s common stock at an amended exercise price of $2.00. During the three months ended March 31, 2013, Comerica Bank exercised all 80,000 of the 2012 Comerica Warrant shares on a cashless basis pursuant to the Notice of Exercise resulting in a net issuance of 40,465 shares of common stock.

Other Borrowings

The Company finances a portion of its annual insurance premiums which it pays in installments over nine months. As of June 30, 2013 and December 31, 2012, $85,000 at an annual interest rate of 3.0% and $379,000 at an annual interest rate of 3.0%, respectively, was outstanding under this arrangement and was included in accrued liabilities in the accompanying consolidated financial statements. The Company incurred interest expense associated with the financed insurance premiums of approximately $1,000 and $4,000 during the three and six months ended June 30, 2013, respectively, and approximately $1,000 and $4,000 during the three and six months ended June 30, 2012, respectively.
