(a)

Diluted earnings (loss) per share reflect the potential dilution from the assumed exercise of all potentially dilutive potential common shares, primarily stock options. For the first quarter of 2011 and the first and third quarters of 2010, the effect of approximately 2,928,000, 2,771,000 and 2,646,000, respectively, of common stock equivalents and outstanding stock options was excluded from the calculation of diluted earnings (loss) per share because the effect was anti-dilutive. For the second third and fourth quarters of 2011 and the second and fourth quarters of 2010, the effect of approximately 2,224,000, 1,717,000, 1,396,350, 1,588,000 and 1,548,000, respectively, of common stock equivalents and outstanding stock options with exercise prices greater than the average market prices for the Company’s common stock was excluded from the calculation of diluted earnings and loss per share because the effect was anti-dilutive.

(b)

Income from continuing operations for the quarter ended December 31, 2010 includes a pretax adjustment of $1,172 and associated tax benefit of $299 for previously unrecorded employer payroll taxes in the Netherlands. The adjustment relates to 2009 and the first three quarters of 2010. The pretax impact arising in 2009 and the first three quarters of 2010 was $667 and $505, respectively, with associated tax benefits of $170 and $129, respectively. The Company does not believe these adjustments are material to either period.

Earnings (loss) per share calculations for each quarter include the weighted average effect for the quarter; therefore, the sum of quarterly earnings (loss) per share amounts may not equal year-to-date earnings (loss) per share amounts, which reflect the weighted average effect on a year-to-date basis.
