Amendments to Articles of Incorporation

In June 2011, we amended our certificate of incorporation to increase the number of shares of authorized common stock to 1,500,000,000, par value $0.01 per share. Prior to the amendment, the number of shares of authorized common stock was 100,000,000, par value $0.01 per share. The certificate of amendment was approved by a majority of our stockholders on June 29, 2011.

Stock Plans

At our annual meeting of stockholders in June 2011, our stockholders approved an amendment to our 2007 Equity Incentive Plan to increase the maximum number of shares of common stock available for grant by 90,000,000 shares of common stock, resulting in an aggregate of 95,000,000 shares of common stock authorized for issuance pursuant to awards granted under our 2007 Equity Incentive Plan. The stockholders also approved an amendment to our 1997 Employee Stock Purchase Plan to increase the number of shares of common stock reserved for issuance under the plan by 500,000, for a total of 1,000,000 shares reserved as of September 30, 2012.

2011 Private Placement

In June 2011, the Company entered into a securities purchase agreement with certain purchasers (2011 Securities Purchase Agreement), pursuant to which the Company agreed to sell for an aggregate price of $24.0 million, 160,000,006 shares of its common stock (2011 Shares) and warrants to purchase 80,000,005 shares of its common stock (Warrants) at an exercise price of $0.18 per share (2011 Private Placement). The 2011 Private Placement closed on July 1, 2011. For each share purchased, the investors received one Warrant to purchase 0.5 shares of common stock (together with a share, a Unit), at a purchase price of $0.15 per Unit. The Warrants were immediately exercisable and expire on the fifth anniversary of the closing date of July 1, 2011. The Warrants may be exercised for cash only or, if a registration statement is not then effective and available for the resale of the shares of common stock issuable upon exercise of the Warrants, by surrender of such Warrant, or a portion of such Warrant, by way of cashless exercise. There is no right to exercise the Warrants to the extent that after giving effect to such exercise the holder would beneficially own in excess of 9.99% of our outstanding shares of common stock (or such other limit as may be designated by any particular purchaser). Each holder of the Warrants can amend or waive the foregoing limitation by written notice to the Company, with such waiver taking effect only upon the expiration of a 61-day notice period.

Under the terms of the 2011 Securities Purchase Agreement, on July 29, 2011, the Company filed a registration statement with the SEC to register for resale the 2011 Shares and the shares of common stock issuable upon the exercise of the Warrants (collectively, the Registrable Securities). The registration statement was declared effective on August 4, 2011. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to the holders of the Registrable Securities liquidated damages in an amount equal to 1.0% per month of such holder's pro rata interest in the total purchase price of the Private Placement, capped at a total penalty of 6.0%.

The Company received advance proceeds of approximately $20.3 million as of June 30, 2011. The remaining $3.7 million was received in July 2011 when the 2011 Private Placement closed. Total proceeds were recorded net of issuance costs of approximately $1.2 million. The 2011 Shares and Warrants were recorded as equity at their fair values on the issuance date.

2012 Private Placement

In July 2012, the Company entered into a securities purchase agreement with certain purchasers, pursuant to which the Company agreed to sell 102,000,000 shares of its common stock (2012 Shares) for an aggregate price of approximately $53.6 million, at a purchase price of $0.525 per share of common stock (2012 Private Placement). The 2012 Private Placement closed on July 30, 2012. The proceeds to the Company from the offering, net of issuance costs, were approximately $50.5 million.

In connection with entering into the securities purchase agreement, the Company also entered into a registration rights agreement. On August 24, 2012, the Company filed a registration statement with the SEC to register the 2012 Shares for resale. The registration statement was declared effective on September 6, 2012. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to each holder of the 2012 Shares an amount equal to 1.5% per month of the aggregate purchase price of the unregistered 2012 Shares held by such holder, capped at a total penalty of 9.0%.
