(a) All exercisable and non-exercisable stock options were not included in the computation of diluted net loss per share at April 30, 2018 and 2017, because their inclusion would have been anti-dilutive. The number of stock options outstanding, which met this anti-dilutive criterion for the three months ended April 30, 2018 and 2017, was 201,000 and 252,000, respectively.
