DERIVATIVE FINANCIAL INSTRUMENTS

(6) DERIVATIVE FINANCIAL INSTRUMENTS

Derivative financial instruments are recognized as a liability on the Consolidated Balance Sheet and measured at their current fair value.

At June 30, 2011 and December 31, 2010, the Company had outstanding warrants to purchase 13,003,221 and 10,336,292 shares of its Common Stock, respectively. Included in these outstanding warrants at June 30, 2011 are warrants to purchase 775,599 shares that are considered to be derivative financial instruments, because the warrant agreements contain “down round” provisions whereby the number of shares covered by the warrants is subject to change in the event of certain future dilutive stock issuances. The fair value of these derivative instruments at June 30, 2011 was approximately $2,526,000 and is included in the Derivative Warrant Liability, a current liability, on the Consolidated Balance Sheet. Changes in the fair value of the derivative financial instruments are recognized in the Consolidated Statement of Operations as a Derivative Warrant Gain or Loss. The Derivative Warrant Loss for the three and six months ended June 30, 2011 was approximately $122,000 and $3,152,000, respectively. The Derivative Warrant Gain for the three and six months ended June 30, 2010 was approximately $376,000 and $672,000, respectively.

The primary underlying risk exposure pertaining to the warrants is the change in fair value of the underlying Common Stock for each reporting period. For the six months ended June 30, 2011, holders exercised warrants with “down round” provisions to purchase 602,693 shares which resulted in a reclassification of $2,171,000 from the Derivative Warrant Liability to Additional Paid-in Capital.
