As further described in Note 5, the exercise price of the Series B Warrants that we issued on May 20, 2011 adjusted to $0.128 at the close of trading on July 5, 2011, which adjustment was retroactively effective to June 29, 2011. Holders of the Series B Warrants that were exercised during the period beginning on June 29, 2011 and ending on July 5, 2011 were entitled to a refund of a portion of their previously paid exercise price if the exercise price adjusted to less than $0.31 per unit. The amount of the refund for each Series B Warrant was equal to the difference between the initial exercise price of the Series B Warrant ($0.31 per unit) and the adjusted exercise price of the Series B Warrant ($0.128 per unit). An aggregate of 6,005,000 warrants were exercised on June 29 and June 30, with respect to which we paid a refund in the aggregate amount of approximately $1.1 million to the warrant holders on July 6, 2011.
