The Investor purchased the Shares and Warrants for a negotiated price of $5.92 per share of common stock purchased. On the Exercise Date, we entered into the Amendment to the warrant agreement. Pursuant to the terms of the Amendment, the exercise price of the Warrants was amended from $20.00 to $8.92 per share, and the Investor concurrently exercised the Warrants for 8,000,000 shares of common stock, resulting in aggregate cash proceeds to the Company of $71.4 million. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Warrants were recorded at fair value at issuance and were adjusted to fair value at each reporting period until the Exercise Date. Any change in fair value between reporting periods was recorded as other income (expense). The Warrants continued to be reported as a liability until they were exercised, at which time the Warrants were adjusted to fair value and reclassified from liabilities to stockholders’ equity. The fair value of the Warrants was estimated using the BSM option pricing model. The fair value of the Warrants on the Exercise Date was $275.5 million, compared with $133.0 million at December 31, 2009. During the years ended December 31, 2010 and 2009, losses of $142.6 million and $118.8 million, respectively, were recognized from valuation of the warrant liability.
