The Company has granted stock options, restricted share units (“RSUs”) and deferred share units (“DSUs”) to employees and non-employee directors under the 2018 Stock Option Plan dated June 28, 2018 (the “2018 Stock Option Plan”), the Employment Inducement Award Plan #1 (the “Employment Inducement Award Plan”), the 2020 Omnibus Equity Incentive Plan dated March 29, 2020 (the “2020 Omnibus Plan”) and the DSU Plan dated August 10, 2019 (the “DSU Plan”). The Company can no longer make grants under the 2018 Stock Option Plan or the Employment Inducement Award Plan.

The following table summarizes the total share-based compensation expense associated with the Company’s stock options and RSUs for the three and six months ended June 30, 2024 and 2023:


	For the three months ended June 30,				For the six months ended June 30,

Vesting conditions for grants of options are determined by the Compensation Committee of the Company’s Board of Directors. The typical vesting for stock option grants made under the 2020 Omnibus Plan is annual vesting over three to five years with a maximum term of ten years. The typical vesting for stock option grants made under the 2018 Stock Option Plan is quarterly vesting over three to five years with a maximum term of seven years. The 2018 Stock Option Plan did not, and the 2020 Omnibus Plan does not, authorize grants of options with an exercise price below fair market value.
