purchased by the Holder in the Subsequent Offering (collectively, the “Shares”) as soon as practicable
following the initial closing (the “Initial Closing”) of the Subsequent Offering (and in any event within

period in Canada under applicable Canadian securities laws, regardless of whether or not the Company has filed and have declared
effective by the SEC the Registration Statement registering the resale in the United States by the Holder of the Shares.”
