Item 4 Summary of Material Change The Corporation closed a non-brokered private placement for gross proceeds of $350,000.

Item 5 Full Description of Material Change On August 31, 2022, the Corporation closed a non-brokered private placement of 35 units (each a "Unit") at a price of $10,000 per Unit for gross proceeds of $350,000. Each Unit consists of one unsecured convertible Debenture and 10,000 stock warrants.

Each Debenture has a term of 36 months ending August 31, 2025 (the "Term") and bears interest at the annual rate of 10%. At the option of the holder of the Debenture, the principal amount of the Debenture may be converted, at any time during the Term, into common shares of the Corporation (each a "Share") at a price of $0.22 per Share. Any accrued interest on the principal, at time of conversion, will be immediately payable in cash.

Each Warrant entitles the holder to purchase one Share at a price of $0.26 per Share, for a period of 18 months ending February 29, 2024. If, at any time following January 1, 2023 the daily volume weighted average trading price of the Shares is or exceeds $0.40 for 15 consecutive trading days, the Corporation shall have the option to accelerate the expiry of the Warrants. If the Corporation chooses to exercise the acceleration right, the new expiry date of the Warrants will be the 30th day following the notice of such exercise.

The proceeds from the Private Placement will be used mainly to fund product development, commercialization of AI-based screening services as well as general and administrative activities.

One director of the Corporation subscribed for 10 Units for a cash consideration of $100,000. Assuming the conversion of the Debentures and exercise of all of his outstanding securities, the director would own 3,250,101 Shares of the Corporation representing 4.61% of the total issued Shares, on a partially diluted basis.
