(1) The net income generated in the first, third and fourth quarters of 2011 were due to the change in the fair value of the warrant derivative liability at each respective quarterly reporting period in 2011. As a result of a decrease in the Company’s stock price at each respective quarter end versus the previous quarter end, the value of the derivative liability decreased, resulting in non-cash income for change in the fair value of the warrant derivative. The loss in the second quarter of 2011 was also due primarily to the change in the fair value of the warrant derivative liability, which was due to the Company’s stock price increasing in value at June 30, 2011, versus March 31, 2011.
