Registered Direct Offering

On March 6, 2015, the Company completed a registered direct offering for gross proceeds of $6,000,000. Net proceeds to the Company, after deducting agent’s fees and offering expenses were $5,377,350. Under the Securities Purchase Agreement, the Company agreed to sell 4,000,000 units at a price of $1.50 per unit. Each unit entitled the purchaser to receive one share of common stock of the Company and a warrant to purchase 0.55 shares of common stock at an exercise price of $2.00 per whole share. The warrants will be exercisable for a period of five years beginning on the six-month anniversary of the original issuance.

At-the-Market Sales

On October 31, 2011, the Company entered into an At-The-Market Sales Agreement with BTIG LLC (the “ATM Sales Agreement”), a major global securities trading firm that acts as our sales agent. Under the ATM Sales Agreement, the Company may from time to time sell shares of its common stock having an aggregate offering amount up to $15,000,000 in “at-the-market” offerings, which shares are registered under the Company’s currently effective registration statement on Form S-3. The Company filed a prospectus supplement dated July 2, 2014 with the Securities and Exchange Commission in connection with the offering, relating to shares of its common stock having an aggregate offering price of up to $4,100,000. The Company pays BTIG a commission equal to 3.0% of the gross proceeds from the sale of any shares pursuant to the ATM Sales Agreement.

During the six months ended June 30, 2015 the Company sold 160,500 shares of common stock for net proceeds of $276,270 under the ATM Sales Agreement. As of August 14, 2015, approximately $6,000,000 of the aggregate $15,000,000 remained available for future sales under the ATM Sales Agreement.

Common Stock Issued for Loan Interest and Fees

As discussed in Note 3 above, unless RCF elects to receive cash, RCF receives common shares of the Company for the payment of interest owing on the RCF Loan. During the six months ended June 30, 2015, the Company issued 239,375 shares of common stock that had a fair value of $380,116 for the settlement of accrued interest for the three-month periods ended December 31, 2014 and March 31, 2015.
