Stockholders’ Equity
 
Private Placement
 
On February 27, 2017, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain accredited investors, pursuant to which the Company agreed to issue and sell to the investors in a private placement (the “Private Placement”) an aggregate of 5,540,000 shares of the Company’s common stock at a purchase price of $0.50 per share. The Company closed the Private Placement on the same day as it entered into the Securities Purchase Agreement and received aggregate gross proceeds of approximately $2.8 million. In connection with the Private Placement, the Company paid an aggregate of $196,000 of financial advisory fees and $40,000 of administrative fees, which were recorded as a reduction of additional paid-in capital.
 
The Securities Purchase Agreement contains a “most-favored nation” provision that provides that if the Company, during 120 days from February 27, 2017, issues or sells any common stock or common stock equivalents reasonably believed to be more favorable in terms or conditions than those in the Private Placement, then the Company must amend the terms of the Securities Purchase Agreement to give the private investors the benefit of such favorable terms or conditions. In connection with the common stock sold in the Public Offering (as defined below) and in accordance with this provision, on April 11, 2017, the Company issued an aggregate of 380,717 shares of its common stock to these investors. On June 23, 2017, the Company held its 2017 annual meeting of stockholders during which the stockholders approved the issuance of the remaining 1,004,283 additional shares of common stock to be issued to the investors, and, following the meeting, on June 23, 2017, the Company issued the remaining shares.
 
Underwritten Public Offering
 
On April 3, 2017, the Company closed an underwritten public offering (the “Public Offering”) of 9,473,250 shares of its common stock at a price to the public of $0.40 per share. The Company received aggregate gross proceeds of approximately $3.8 million. In connection with the Public Offering, the Company paid an aggregate of $365,000 of financial advisory fees and $92,000 of administrative fees, which were recorded as a reduction of additional paid-in capital. The shares of common stock were issued pursuant to the Company’s shelf registration statement on Form S-3 previously filed with the Securities and Exchange Commission and declared effective on September 25, 2014.
 
On April 3, 2017, the Company issued warrants to purchase an aggregate of 236,831 of the Company’s common stock to the underwriter of this offering. These warrants are immediately exercisable, have an exercise price of $0.44, and expire on March 29, 2022. The warrants had an aggregate issuance date fair value of $78,000 which was recorded as both a debit and credit to additional paid in capital.
 
Pursuant to an anti-dilution provision provided in the warrants dated November 8, 2012 to purchase common stock at an initial exercise price of $2.19, the exercise price of these warrants was adjusted to the public offering price of $0.40. As of April 3, 2017, November 2012 warrants to purchase 362,293 shares of the Company’s common stock were outstanding. These warrants expire in November 2017.
