Due to the net loss in the second quarter of 2009, the assumed exercise of certain stock options were excluded from the computation of diluted loss per share.

Certain stock-based compensation awards were not included in the computation of diluted earnings per share for the three- and six-month periods ended June 30, 2009 and 2008, since inclusion of these awards would have anti-dilutive effects.
