__________
(a) 
For the three and nine months ended September 30, 2013, the number of anti-dilutive securities which were excluded from the computation of diluted earnings per share was not significant. For the three and nine months ended September 30, 2012, 0.2 million outstanding options and 8.9 million warrants have an anti-dilutive effect and therefore are excluded from the computation of diluted weighted average shares outstanding.
