The Company also wishes to correct an error contained in its press release issued on December 19, 2022 regarding the vesting period of the 150,000 stock options granted to Sonja Rossteuscher, Chief Financial Officer of the Company. The December 19, 2022 press release incorrectly indicated that the stock options granted to Mrs. Rossteuscher had a 36-months vesting period from the grant date of December 15, 2022, while in fact the vesting period of such stock options is 24-months following the grant date.
