Common and preferred stock

10. Common and preferred stock

In June 2011, the Company’s stockholders approved an increase in its authorized shares of common stock from 200,000,000 to 250,000,000. As such, the Company is authorized to issue 250,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of undesignated preferred stock, par value $0.01 per share, issuable in one or more series designated by the Company’s board of directors. No other class of capital stock is authorized. As of June 30, 2011 and December 31, 2010, 130,905,582 and 127,793,178 shares of common stock, respectively, were issued and outstanding. Included in the common stock outstanding as of June 30, 2011 are 9,000,000 shares of common stock loaned to Bank of America under a share lending agreement in connection with the offering of the $100 million aggregate principal amount of 5.75% Senior Convertible Notes due 2015 (see Note 13 — Senior convertible notes). Bank of America is obligated to return the borrowed shares (or, in certain circumstances, the cash value thereof) to the Company on or about the 45th business day following the date as of which the entire principal amount of the notes ceases to be outstanding, subject to extension or acceleration in certain circumstances or early termination at Bank of America’s option. The Company did not receive any proceeds from the sale of the borrowed shares by Bank of America, but the Company did receive a nominal lending fee of $0.01 per share from Bank of America for the use of borrowed shares.

In August 2010, the Company entered into an agreement with Seaside 88, LP (“Seaside”) for the sale of up to 18,200,000 shares of common stock in increments of 700,000 shares on a bi-weekly basis with the first closing date scheduled for September 22, 2010 provided that certain conditions are met, including for a particular closing to take place, the ten-day volume weighted average trading price for the Company’s common stock immediately prior to such closing must meet or exceed a minimum priced set by the Company at $6.50 per share. If the ten-day volume weighted average trading price for a particular closing is below $6.50 per share, then that closing will not occur and the aggregate number of shares to be purchased will be reduced by 700,000 shares. The purchase price per share at each closing will be equal to 92% of that 10-day volume weighted average price. The agreement with Seaside will terminate on the day following the final closing under the agreement, or the Company may terminate the Seaside agreement at any time upon written notice. During the quarter ended March 31, 2011, the Company issued and sold a total of 1.4 million shares of common stock to Seaside for net proceeds of $9.7 million. During the three months ended June 30, 2011, no shares of common stock were sold to Seaside under this agreement. As of June 30, 2011, the Company had issued and sold a total of 3,500,000 shares of common stock to Seaside for net proceeds of $23.8 million in accordance with the agreement, and a total of 3,500,000 shares remained subject to future sale if the Company is able to satisfy the conditions precedent for sales of shares under the agreement, including the minimum price requirement.

In conjunction with the Seaside agreement, in August 2010, the Company entered into a common stock purchase agreement with The Mann Group LLC (“The Mann Group”), an entity controlled by the Company’s principal stockholder. Under this common stock purchase agreement, the Company is required to issue and sell, and The Mann Group is obligated to purchase at a price equal to the greater of $7.15 per share (the closing bid price of the Company’s common stock on August 10, 2010) and the closing bid price of common stock on the trading day immediately preceding the applicable closing date, the same number of shares of the Company’s common stock that Seaside purchases on each closing date under its agreement with the Company (see Note 12 — Related-party arrangements). During the quarter ended March 31, 2011, the Company issued and sold a total of 1.4 million shares of common stock to The Mann Group that resulted in reduction in the note payable to related party of $11.1 million. During the three months ended June 30, 2011, no shares of common stock were sold to The Mann Group under this agreement. As of June 30, 2011, the Company had issued and sold a total of 3,500,000 shares of common stock to The Mann Group that had resulted in total reduction in the note payable to related party of $27.8 million, and a total of 3,500,000 shares remained subject to future sale.
