Promissory Note, dated April 14, 2023

Interest. The Principal Amount shall bear interest at the rate of 4.25% per year from the Issue Date to, but excluding, the Maturity Date (as defined below). Interest is payable in arrears on the Maturity Date. Interest on the Principal Amount shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. Solely for the purposes of disclosure under the Interest Act (Canada), the annual rate of interest to which the rate of interest provided in this Note is equivalent in respect of any period is the rate so determined multiplied by the actual number of days in the calendar year in which such period ends and divided by 360.

Maturity Date. The unpaid Principal Amount plus all accrued and unpaid interest owing under this Note will be due and payable on December 31, 2024 (the “Maturity Date”).

Prepayment. At any time prior to the Maturity Date, the Corporation may, upon 10 business days prior notice, prepay, without penalty or bonus, the Principal Amount either in whole at one time or in part from time to time, together with all accrued and unpaid interest to the date fixed for repayment and, in the case of prepayment in whole, all other monies owing under this Note.
