Exclusive global agreement ("Meros License Agreement")

In 2017, the Corporation was granted by Meros

Polymers Inc. ("Meros") the sole, exclusive, irrevocable license to patented nanotechnologies for use with any drugs to diagnose,

or treat, cardiovascular disease, cardiopulmonary disease, and cardiac arrhythmias. Meros is focused on the advancement of nanotechnologies

developed at the University of Alberta.

Under the Meros License Agreement, Cardiol agreed

to certain milestones and milestone payments, including the following: (i) payment of $100,000 upon enrolling the first patient in

a Phase IIB clinical trial designed to investigate the safety and indications of efficacy of one of the licensed technologies; (ii) payment

of $500,000 upon enrolling the first patient in a Pivotal Phase III clinical trial designed to investigate the safety and efficacy of

one of the licensed technologies; (iii) $1,000,000 upon receiving regulatory approval from the FDA for any therapeutic and/or prophylactic

treatment incorporating the licensed technologies. Cardiol also agreed to pay Meros the following royalties:

of worldwide proceeds of net sales of the licensed technologies containing cannabinoids, excluding non-royalty sub-license income in (b) below,

that Cardiol receives from human and animal disease indications and derivatives as outlined in the Meros License Agreement;

of any non-royalty sub-license income that Cardiol receives from human and animal disease indications and derivatives for licensed technologies

containing cannabinoids as outlined in the Meros License Agreement;

of worldwide proceeds of net sales that Cardiol receives from the licensed technology in relation to human and animal cardiovascular and/or

cardiopulmonary disease, heart failure, and/or cardiac arrhythmia diagnosis and/or treatments using the drugs, excluding cannabinoids

included in (a) above, outlined in the Meros License Agreement; and

of any non-royalty sub-license income that Cardiol receives in relation to any human and animal heart disease, heart failure and/or arrhythmias

indications, excluding cannabinoids included in (b) above, as outlined in the Meros License Agreement.

In addition, as part of the consideration under

the Meros License Agreement, Cardiol (i) issued to Meros 1,020,000 common shares; and (ii) issued to Meros 1,020,000 special

warrants convertible automatically into common shares for no additional consideration upon the first patient being enrolled in a Phase

1 clinical trial using the licensed technologies as described in the Meros License Agreement.

(i) When measuring the lease liability for

the property lease that was classified as an operating lease, the Corporation discounted the lease payments using its incremental borrowing

rate. The property lease expires on May 31, 2024, and the lease payments were discounted with a 9% interest rate.

On November 5, 2021, the Corporation

issued 8,175,000 warrants as part of a unit financing. Each warrant is exercisable into one common share at the price of USD$3.75

per share for a period of three years from closing. The original estimated fair value of $11,577,426 was assigned to the 8,175,000

warrants issued by using a fair value market technique incorporating the Black-Scholes option pricing model, with the following

assumptions: a risk-free interest rate of 1.01%; an expected volatility factor of 81%; an expected dividend yield of 0%; and an

expected life of 3 years. The only significant unobservable input is the volatility, which could cause an increase or decrease in

fair value. The warrants have been classified as a derivative liability on the statement of financial position and are re-valued at

each reporting date, as the warrants were issued in a currency other than the Corporation's functional currency. As at June 30,

2023, the fair value of the derivative liability was $1,202,713 (December 31, 2022 - $419,901), resulting in an increase in the

value of the derivative liability for the three and six months ended June 30, 2023 of $856,893 and $782,812 (three and six

months ended June 30, 2022 - decrease in fair value of $861,600 and $2,994,117).

Significant assumptions used in determining the fair value of the derivative

warrant liabilities are as follows:

The authorized share capital consists of an unlimited number of common

shares. The common shares do not have a par value. All issued shares are fully paid.

b) Common shares issued
