11. | Stockholders’ Equity
Preferred Stock The Company has authorized 5,000,000 shares of preferred stock, par value $0.001 per share. The Company’s Board of Directors is authorized to designate the terms and conditions of any preferred stock we issue without further action by the common stockholders. There were 13,500 shares of Series A 3.6% Convertible Preferred Stock and 10,000 Series B Convertible Preferred Stock that had been issued at June 30, 2018 and December 31, 2017, respectively. There were no shares of Series A 3.6% Convertible Preferred Stock outstanding as of either date. There were 1,186 and 2,431 shares of Series B Convertible Preferred Stock outstanding as of June 30, 2018 and December 31, 2017, respectively. On July 25, 2018, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of Series C Convertible Preferred Stock (the “Certificate of Designation”) with the Delaware Secretary of State creating a new series of its authorized preferred stock, par value $0.001 per share, designated as the Series C Convertible Preferred Stock (the “Series C Preferred Stock”). The number of shares initially constituting the Series C Preferred Stock was set at 7,000 shares. Pursuant to a registration statement on Form S-1 originally filed on April 27, 2018, as amended, and became effective on July 17, 2018, and related prospectus (as supplemented), the Company registered and distributed to holders of its common stock and Series B Convertible Preferred Stock, at no charge, non-transferable subscription rights to purchase up to an aggregate of 20,000 units each consisting of one share of Series C Preferred Stock and 1,050 warrants for $1,000 per unit. Each warrant is exercisable for one share of the Company’s common stock at an exercise price of $0.7986 per share for 30 months from the date of issuance and each share of Series C Preferred Stock is convertible into 1,253 shares of the Company's common stock. Pursuant to the 2018 Rights Offering, which closed on July 25, 2018, the Company sold an aggregate of 6,723 units, resulting in total net proceeds to the Company of approximately $5.7 million. Holders of Series C Preferred Stock shall be entitled to receive dividends (on an as-if-converted-to-common-stock basis) in the same form as dividends actually paid on shares of the Company’s common stock when, as and if such dividends are paid on shares of common stock. Except as otherwise provided in the Certificate of Designation or as otherwise required by law, the Series C Preferred Stock has no voting rights. Upon the Company’s liquidation, dissolution or winding-up, whether voluntary or involuntary, holders of Series C Preferred Stock will be entitled to receive out of the Company’s assets, whether capital or surplus, an amount equal to the $1,000 stated value per share for each share of Series C Preferred Stock before any distribution or payment shall be made to the holders of any junior securities. The Company is not obligated to redeem or repurchase any shares of Series C Preferred Stock. Shares of Series C Preferred Stock are not otherwise entitled to any redemption rights, or mandatory sinking fund or analogous fund provisions. Common Stock On December 22, 2016, the Company entered into a Purchase Agreement (the “Lincoln Park Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”) pursuant to which the Company has the right to sell to Lincoln Park and Lincoln Park is obligated to purchase up to $20.0 million in amounts of shares, of the Company’s common stock, over the 30-month period following March 30, 2017. The Company may direct Lincoln Park, at its sole discretion and subject to certain conditions, to purchase up to 10,000 shares of common stock on any business day but in no event will the amount of a single Regular Purchase (as defined in the Lincoln Park Purchase Agreement) exceed $1.0 million. The purchase price of shares of common stock related to the Regular Purchases will be based on the prevailing market prices of such shares at the time of sales. The Company’s sales of shares of common stock to Lincoln Park under the Lincoln Park Purchase Agreement are limited to no more than the number of shares that would result in the beneficial ownership by Lincoln Park and its affiliates, at any single point in time, of more than 9.99% of the then outstanding shares of the common stock. There are no trading volume requirements or restrictions under the Lincoln Park Purchase Agreement. There is no upper limit on the price per share that Lincoln Park must pay for common stock under a Regular Purchase or an accelerated purchase and in no event will shares be sold to Lincoln Park on a day our closing price is less than the floor price of $5.00 per share as set forth in the Purchase Agreement. On December 22, 2016, we issued to Lincoln Park 12,742 shares of common stock with a market value on the date of issuance of approximately $0.2 million as commitment shares in consideration for entering into the Lincoln Park Purchase Agreement. The Company will issue up to an additional 38,226 shares of common stock on a pro rata basis to Lincoln Park only as and when shares are sold under the Lincoln Park Purchase Agreement to Lincoln Park. Through June 30, 2018, the Company sold a total of 199,472 shares under the Lincoln Park Purchase Agreement, for proceeds of approximately $1.7 million. On April 11, 2017, we entered into an underwriting agreement with Maxim relating to the issuance and sale of 0.9 million shares of our common stock, par value $0.001 per share. The price to the public in the offering is $11.00 per share. Maxim agreed to purchase the shares from us pursuant to the Underwriting Agreement at a price of $10.40 per share. The net proceeds to us from the offering were approximately $8.7 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. The offering closed on April 17, 2017. In addition, under the terms of the underwriting agreement, we granted Maxim a 45-day overallotment option to purchase up to 94,400 additional shares of common stock. On May 31, 2017, Maxim exercised their overallotment option and purchased 84,900 shares at $11.00 per share. The net proceeds to us were $0.8 million, after deducting underwriting costs and offering expenses payable by us. On June 1, 2018, the Company entered into a Sales Agreement with B. Riley FBR, Inc. (“B. Riley FBR”) to sell shares of its common stock, par value $0.001, having an aggregate offering price of up to $6.5 million from time to time, through an “at the market” equity offering program (the “ATM program”) under which B. Riley FBR will act as sales agent.
