The 9% Notes, issued January 31, 2013, bear interest at a rate of 9% per annum, payable semi-annually on August 15 and February 15, and mature February 15, 2016, and are subordinated. The principal of the 9% Notes plus any accrued yet unpaid interest is convertible at any time by the holder at a conversion price of $4.00 per share of the Company’s common stock, subject to adjustment for stock splits, stock dividends and reverse stock splits. On 60 days’ prior notice, 9% Notes are callable in full or in part by the Company at any time after January 31, 2015. If the Average Daily Value of Trades (“ADVT”) during the prior 90 days as reported by Bloomberg is greater than $100,000, the 9% Notes are callable at a price of 105% of the 9% Notes’ par value, and if the ADVT is less than $100,000, the 9% Notes are callable at a price of 110% of the 9% Notes’ par value.

In connection with the issuance of the 9% Notes, the holders of the 9% Notes received warrants to purchase 66,000 shares of the Company’s common stock at an exercise price of $4.50 per share, subject to adjustment for stock splits, reverse stock splits and stock dividends, and which are exercisable at any date prior to January 31, 2018, and were classified in equity.
