2015 Stock Option Plan

The Company maintains the 2015 Stock Option Plan (“2015 Option Plan”), originally referred to as the 2007 Option Plan. In June 2015, the 2015 Option Plan was amended from a fixed option plan to a rolling share option plan pursuant to which the Company is authorized to grant options of up to 20% of its issued and outstanding Common Shares.

As of March 31, 2023 and December 31, 2022, the Company had 396,080 options available for grant under the 2015 Option Plan.
