FOR VALUE RECEIVED, MEDICUS PHARMA LTD., an entity organized under the laws of the Province of Ontario, Canada (the "Company"), hereby promises to pay to the order of YA II PN, Ltd., or its registered assigns (the "Holder") the amount set out above as the principal amount (as reduced or increased pursuant to the terms hereof pursuant to redemption or otherwise, the "Principal") when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest ("Interest") on any outstanding Principal at the applicable Interest Rate from the date set out above as the Debenture Issuance Date (the "Issuance Date") until the same becomes due and payable, whether upon the Maturity Date or acceleration, redemption or otherwise (in each case in accordance with the terms hereof). This Debenture (including all debentures issued in exchange, transfer or replacement hereof, this "Debenture") was originally issued pursuant to the Securities Purchase Agreement dated as of May 2, 2025, as it may be amended from time to time (the "Securities Purchase Agreement") between the Company and the Buyers listed on the Schedule of Buyers attached thereto.  Certain capitalized terms used herein are defined in Section (14).

(1) GENERAL TERMS

(a) Maturity Date. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest, and any other amounts outstanding pursuant to the terms of this Debenture. The "Maturity Date" shall be February 2, 2026, as may be extended upon joint consent of the Holder and the Company. 

(b) Interest Rate and Payment of Interest. Interest shall accrue on the outstanding Principal balance hereof at an annual rate equal to 8.00% ("Interest Rate"), which Interest Rate shall increase to an annual rate of 18.00% upon an Event of Default (for so long as such event remains uncured). Interest shall be calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law.

(c) Payment Dates. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day. 

(2) PAYMENTS

(a) Monthly Payments.  The Company shall make monthly payments beginning on the 60^th day following the Issuance Date and continuing on the same day of each successive Calendar Month (a "Monthly Payment Date"). The monthly payments shall be in an amount equal to the sum of (i) (x) in respect of the first six monthly payments, $500,000 of Principal (in the aggregate among this Debenture and all Other Debentures), or the outstanding Principal, if the Principal (in the aggregate among this Debenture and all Other Debentures) is less than such amount or (y) in respect of the monthly payment due on the Maturity Date, $2,000,000 of Principal (in the aggregate among this Debenture and all Other Debentures), or the outstanding Principal, if the Principal (in the aggregate among this Debenture and all Other Debentures) is less than such amount, plus (ii) the accrued and unpaid Interest hereunder as of each Monthly Payment Date (such aggregate monthly payment amount, the "Monthly Payment Amount"). If this Debenture and any Other Debentures are held by more than one holder, then the Monthly Payment Amount shall be allocated to each holder based on each holder's pro-rata portion of the total outstanding Principal amount outstanding on this Debenture and all Other Debentures. If this Debenture and all Other Debentures are held by one holder, then such holder shall decide the allocation of payments between this Debenture and all Other Debentures in its sole discretion. 100% of the proceeds from sales of Common Shares made during any Calendar Month pursuant to that certain Standby Equity Purchase Agreement, dated as of February 10, 2025, entered into by and between the Company and the Holder (the "SEPA"), shall be retained by the Holder and offset the Monthly Payment Amount for such Calendar Month. Once proceeds from sales of Common Shares made during a Calendar Month pursuant to the SEPA exceed the Monthly Payment Amount for such Calendar Month, the Holder shall retain 50% of the proceeds from sales of Common Shares made during such Calendar Month pursuant to the SEPA and apply such proceeds to future payments due hereunder, which amounts shall be applied first to amounts due on the Maturity Date  and thereafter to prior due amounts in reverse chronological order of their due dates. All payments shall be applied first to any amounts due hereunder other than Principal and Interest, then to accrued and unpaid Interest, and finally to Principal.

(b) The Company at its option shall have the right, but not the obligation, to redeem ("Optional Redemption") in cash, at any time, a portion or all amounts outstanding under this Debenture at the Redemption Amount (as defined below) as described in this Section. The "Redemption Amount" shall be an amount equal to (a) the outstanding Principal balance being redeemed by the Company, plus (b) all accrued and unpaid Interest hereunder as of such redemption date. 

(3) EVENTS OF DEFAULT.

(a) An "Event of Default", wherever used herein, means any one of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

The failure of the Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Debenture. Any waiver must be in writing.

(13) If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any Interest or other amount deemed Interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest.
