Common Stock Transaction

March 2016 Offering

On March 29, 2016, we entered into a Stock Purchase Agreement with fifteen investors for the offer and sale of 25,245,442 shares of Common Stock and warrants to purchase an additional 25,245,442 shares of Common Stock at a purchase price of $0.0713 per unit, with each unit consisting of one share and one warrant to purchase Common Stock, for an aggregate purchase price of $1,800,000 (the “March 2016 Offering). The issue price of the shares sold was based on a 10% discount to the average closing price between March 7, 2016 and March 11, 2016 and the warrant exercise price was based on a 10% premium to the same average closing price. The warrants have an exercise price of $0.0871 per share and a five-year term. The warrants also include cashless exercise provisions and a “full ratchet” anti-dilution provision under which the exercise price of such warrants resets to any lower sales price at which the Company offers or sells Common Stock or Common Stock equivalents for one year (subject to standard exceptions).

The March 2016 Offering resulted in gross proceeds of $1,800,000, of which $1,439,000 was received in March 2016 and $361,000 was received in April 2016. As part of the offering expenses, we paid to a European placement agent a referral fee of $29,000 which is equal to 10% of the gross proceeds, provided that the investors referred by such placement agent were not U.S. Persons and were solicited outside the United States.

Purchasers in the March 2016 Offering include Michael I. Sacks ($1,000,000), the father of Bradley J. Sacks, the Chairman of our Board of Directors, Centric Capital Ventures, LLC ($19,000), an investment entity controlled by Bradley J. Sacks, Terrance K. Wallberg ($50,000), our Vice President and Chief Financial Officer, and Daniel G. Moro ($10,000), our Vice President of Polymer Drug Delivery.
