Weighted average shares outstanding:
Weighted average common stock outstanding	38,654	38,798	38,683	38,734

Total weighted average shares outstanding assuming dilution	38,479	37,850	38,052	37,770

¹Due to net losses, stock options and restricted stock units representing 291,000, 119,000 and 115,000 have been excluded from the number of shares used in calculating diluted loss per share, as their inclusion would be antidilutive for the six months ended June 30, 2011 and the three and six months ended June 30, 2010, respectively.
