12. | Preferred Stock, Common Stock and Warrants
Authorized Shares On May 29, 2013 the stockholders approved an increase in the number of authorized shares of common stock from 250,000,000 to 350,000,000. The increase in authorized shares was effected pursuant to a Certificate of Amendment to the Sixth Amended and Restated Certificate of Incorporation (the "Certificate of Amendment"), filed with the Secretary of State of the State of Delaware on May 30, 2013 Preferred Stock Outstanding As of December 31, 2013 there were 5,000,000 shares of preferred stock authorized and no shares outstanding. In October 2013 the Company sold 43,430 shares of $0.001 par value Series B Convertible Preferred Stock for a purchase price of $1,075 per share and gross proceeds of approximately $46.7 million in an underwritten public offering. After issuance costs of approximately $2.5 million, the net proceeds from the offering were approximately $44.2 million. Each share of Series B Convertible Preferred Stock is convertible into 1,000 shares of common stock at any time at the holder’s option. However, the holder is prohibited from converting the Series B Convertible Preferred Stock into shares of common stock if, as a result of such conversion, the holder and its affiliates would own more than 9.98% of the total number of shares of common stock then issued and outstanding. In the event of the Company’s liquidation, dissolution, or winding up, holders of Series B Convertible Preferred Stock will receive a payment equal to $0.001 per share before any proceeds are distributed to the common stockholders. Shares of Series B Convertible Preferred Stock generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series B Convertible Preferred Stock is required to amend the terms of the Series B Convertible Preferred Stock. Holders of Series B Convertible Preferred Stock are not entitled to receive any dividends, unless and until specifically declared by the Company’s board of directors. The Series B Convertible Preferred Stock ranks senior to the Company’s common stock as to distributions of assets upon the Company’s liquidation, dissolution or winding up, whether voluntarily or involuntarily. The Series B Convertible Preferred Stock may rank senior to, on parity with or junior to any class or series of the Company’s capital stock created in the future depending upon the specific terms of such future stock issuance. The fair value of the common stock into which the Series B Convertible Preferred Stock is convertible exceeded the allocated purchase price of the Series B Convertible Preferred Stock by $8.5 million on the date of issuance, for which the Company recorded a deemed dividend. The Company recognized the deemed dividend equal to the number of shares of Series B Convertible Preferred Stock sold on October 30, 2013 multiplied by the difference between the value of the common stock and the Series B Convertible Preferred Stock conversion price per share on that date. The dividend was reflected as a one-time, non-cash, deemed dividend to the holders of Series B Convertible Preferred Stock on the date of issuance, which is the date the stock first became convertible. Preferred Stock Rights On November 4, 2008, our Board of Directors declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of our Common Stock, par value $0.001 per share (the “Common Shares”). The dividend was payable on November 17, 2008 to the stockholders of record on that date. Each Right entitles the registered holder to purchase from us one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share (the “Preferred Shares”), at a price of $6.00 per one one-hundredth of a Preferred Share, subject to adjustment. Upon the acquisition of, or announcement of the intent to acquire, 20 percent or more of our outstanding Common Shares by a person, entity or group of affiliated or associated persons (“Acquiring Person”), each holder of a Right, other than Rights held by the Acquiring Person, will have the right to purchase that number of Common Shares having a market value of two times the exercise price of the Right. If we are acquired in a merger or other business combination transaction or 50 percent or more of our assets or earning power are sold to an Acquiring Person, each holder of a Right will thereafter have the right to purchase, at the then current exercise price of the Right, that number of shares of common stock of the acquiring company which at the time of such transaction will have a market value of two times the exercise price of the Right. The Rights plan is intended to maximize the value of the Company in the event of an unsolicited attempt to take over the Company in a manner or on terms not approved by the Company’s Board of Directors. The Rights will expire on November 17, 2018, unless the Rights are earlier redeemed or exchanged by the Company. Common Stock Outstanding In October 2013 we completed an underwritten public offering of 79,570,000 shares of our common stock to the public at $1.075 per share. The gross proceeds to us from this offering were approximately $85.5 million. After deducting issuance costs of approximately $4.5 million, the net proceeds from the offering were approximately $80.9 million. On March 29, 2013, we entered into an At Market Issuance Sales Agreement (the “Agreement”) with MLV & Co. LLC (“MLV”) under which we may offer and sell our common stock having aggregate sales proceeds of up to $50,000,000 from time to time through MLV as our sales agent. Sales of our common stock through MLV, if any, will be made by means of ordinary brokers’ transactions on the NASDAQ Capital Market or otherwise at market prices prevailing at the time of sale, in block transactions, or as otherwise agreed upon by us and MLV. MLV will use commercially reasonable efforts to sell our common stock from time to time, based upon instructions from us (including any price, time or size limits or other customary parameters or conditions we may impose). We will pay MLV a commission of up to 3.0% of the gross sales proceeds of any common stock sold through MLV under the Agreement. No sales of our common stock have taken place under this Agreement as of December 31, 2013. On May 9, 2012, we completed an underwritten public offering of 17,500,000 shares of our common stock to the public at $4.25 per share. The net proceeds to us from this offering were $69.6 million, after deducting offering expenses. On November 3, 2011, we completed an underwritten public offering of 27,600,000 shares of our common stock including 3,600,000 shares sold pursuant to the full exercise of an overallotment option previously granted to the underwriters at a price to the public of $2.50 per share. The net proceeds to us from this offering were $64.5 million, after deducting offering expenses. On November 2, 2010, we completed an underwritten public offering of 26,450,000 shares of our common stock including 3,450,000 shares sold pursuant to the full exercise of an overallotment option previously granted to the underwriters at a price to the public of $1.70 per share. The net proceeds to us from this offering were $42.0 million, after deducting offering expenses. On September 20, 2010, we entered into a Purchase Agreement with Aspire Capital, which provided that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital was committed to purchase up to an aggregate of $30.0 million of shares of our common stock (the “Purchase Shares”) over the 25-month term of the Purchase Agreement. Under the Purchase Agreement, we agreed to pay Aspire Capital a commitment fee equal to 4% of $30 million in consideration for Aspire Capital’s obligation to purchase up to $30 million of our common stock. We paid this commitment fee of $1.2 million by the issuance of 600,000 shares of our common stock and this fee was recorded as a cost of raising capital and netted against the gross proceeds from the Purchase Agreement in September 2010. During 2010, we sold 2,350,000 shares of common stock to Aspire Capital for $3.3 million and during 2011 we sold 10,995,210 shares of common stock for $26.7 million, which totaled the proceeds available to us of $30 million under the Purchase Agreement. On April 16, 2010, we completed an underwritten public offering resulting in net proceeds of $41.1 million, after deducting offering expenses of approximately $3.0 million, from the sale of 30,293,000 units at a per unit price of $1.4525. Each unit consisted of one share of common stock and one warrant to purchase 0.5 of a share of common stock. Each warrant has an exercise price of $1.50 per share, and is exercisable for a period of five years from the date of issuance. From this offering, warrants to purchase an aggregate of 10,913,873 shares of our common stock were outstanding as of December 31, 2013 (including the warrants to purchase 6,765,128 shares provided to Symphony as described in Note 8 “Symphony Dynamo, Inc.”).
