9. Financing Transaction

On May 9, 2014, we entered into a securities purchase agreement (the “Purchase Agreement”) with an accredited institutional investor pursuant to which we agreed to issue 2,500,000 shares of our common stock at a price of $4.00 per share (the “Investor Shares”) and a warrant (the “Investor Warrant”) for an aggregate purchase price of $10,000,000 in gross proceeds and net proceeds of approximately $9.3 million after expenses and fees, including a placement agent fee described below. Full exercise of the Investor Warrant will result in us receiving an additional $12,725,000 in gross proceeds, excluding any placement agent fee paid as described below. Closing of the investment transaction pursuant to the Purchase Agreement occurred on May 15, 2014. In accordance with a registration rights agreement with the investor (the “Registration Rights Agreement”), we filed a registration statement with the SEC to register the Investor Shares and the shares of our common stock issuable upon exercise of the Investor Warrant (the “Investor Warrant Shares”) that became effective on June 12, 2014.

The terms of the Investor Warrant provide that it may be exercised to purchase up to an aggregate of 2,500,000 shares of our common stock at an exercise price of $5.09 per share for a period of 18 months from the May 15, 2014 issuance date. The holder may exercise the Investor Warrant in whole or in part. The terms of the Investor Warrant require that exercise may only be for cash and not a cashless basis unless, after a period of six months from May 15, 2014 issuance date, there has been a failure to maintain the effective registration of the Investor Warrant Shares. The exercise price of the Investor Warrant is subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions a “fundamental event” or “stock combination event” as provided for in the terms of the Investor Warrant.

In connection with the sale of the Investor Shares, we paid a fee to a placement agent of $600,000, and have further agreed to pay a fee to the placement agent of up to $600,000 in connection with exercise(s) of the Investor Warrant. In addition, we issued to the placement agent a warrant (the “Agent Warrant”) exercisable for a period of 18 months from the issuance date of May 15, 2014 to acquire up to an aggregate of 75,000 shares of our common stock.
