the period ended May 31, 2013, Xzeres has incurred net losses from continuing operations and, therefore, has no tax liability.
The net deferred tax asset generated by the loss carry-forward has been fully reserved. The cumulative net operating loss carry-forward
is approximately $23,450,000 at May 31, 2013, and will expire beginning in the year 2029. The cumulative tax effect at the expected
rate of 34% of significant items comprising our net deferred tax amount is as follows:&lt;/font&gt;&lt;/p&gt;
