(1) For quarter ended October 31, 2011, excludes the effect of nil options
(2010 - 222,550) as the exercise price exceeded the average fair market
value of the common stock during the period and hence are anti-dilutive. For
six months ended October 31, 2011, excludes the effect of nil options (2010
- 228,550).
(2) The calculation of the weighted average number of common shares excludes
any issued DSUs as the DSUs will be settled with cash, and any unissued
shares related to the ESPP.
