[1] The Company identified an immaterial error in its computation of loss per share for the quarter ended September 30, 2011. The Company had incorrectly allocated the net loss to each class of common stock and participating security under the two-class method. The net loss for this period should have been fully allocated to the class of common stock. The impact of this immaterial error correction is to change loss per share for the quarter ended September 30, 2011 to $(0.33) from $(0.31) as previously reported. The Company does not believe that this adjustment is material to any of its previously-filed quarterly or annual consolidated financial statements.

[2] Participating securities include 956,207and 1,212,551 nonvested restricted shares for the quarters and year to date periods ended September 30, 2012 and 2011, respectively, as well as 196,264 and 0 restricted share units for the quarters and year to date periods ended September 30, 2012 and 2011, respectively.

[3] Under the two-class method, basic weighted average common shares exclude outstanding nonvested participating securities consisting of restricted share awards of 956,207 and 1,212,551 for the quarters and year to date periods ended September 30, 2012 and 2011, respectively.

[4] Anti-dilutive shares related to stock options totaled 30,000 and 61,100 for the quarters ended September 30, 2012 and 2011, respectively, and 22,667 and 44,733 for the year to date periods ended September 30, 2012 and 2011, respectively. Potential dilutive securities have not been included in the earnings (loss) per share computation in a period when a loss is experienced.
