This Note is issued pursuant to that certain Convertible Note Purchase Agreement dated March 15th, 2024 (the “Purchase Agreement”) by and between the Company and the Holder, and the resolutions of the board of directors and shareholders of the Company passed on or about the same date, and is subject to the provisions thereof. Any capitalized term used but not defined herein shall have such meaning ascribed to them in the Purchase Agreement.

The following is a statement of the rights of the Holder and the conditions to which this Note is subject, and to which the Holder, by the acceptance of this Note, agrees:

1.Interest. Subject to Section 4 hereof, the interest (the “Interest”) shall accrue from the date of the Note on the unpaid Principal Amount at a rate of four point five percent (4.5%) on an annual non-compound basis, computed on the basis of actual calendar days elapsed and a year of 365 days, subject to the terms and conditions of this Note.

A-1

2.Maturity and Extension. The Principal Amount plus all accrued and unpaid Interest thereon shall be due and payable on the day which is twenty-four (24) months from the date hereof (the “Original Maturity Date”), except and to the extent all or a portion of this Note shall have been previously repaid, redeemed or converted pursuant to Sections 3 and 4 hereof. The Original Maturity Date may be extended for an additional twelve (12) months by the Company at its sole discretion by giving written notice to the Holder at least thirty (30) days prior to the Original Maturity Date (the last day of such extended period of the Note is referred to as the “Extended Maturity Date.”) (The Extended Maturity Date together with the Original Maturity Date shall be collectively referred to as the “Maturity Date.”)

3.Repayments.

(a)Form of Payment. All payments of Principal Xxxxxx and Interest (other than payment by way of conversion) shall be made in U.S. dollars to the Holder and be remitted to the bank account specified by Xxxxxx in a written notice delivered to the Company.

(b)Repayment. Except for the portion of the Principal Amount which has been converted into Conversion Shares (as defined below), the total outstanding Principal Amount of the Note plus all accrued and unpaid Interest thereon shall be due and payable upon the date that is the earlier of: (i) the Maturity Date; or (ii) upon the occurrence of an Event of Default (as defined below)., or (iii) upon the occurrence of a Deemed Liquidation Event (as defined in the Company’s Seventh Amended and Restated Memorandum and Articles of Association).

(c)Prepayment.

(g)No Fractional Shares. If any fractional share of capital stock would, except for the provisions hereof, be deliverable upon conversion of this Note, the Company, in

A-3

lieu of delivering such fractional share, shall pay an amount equal to the value of such fractional share, as determined by the per share conversion price used to effect such conversion.

(j)Termination of Rights. All rights with respect to this Note shall terminate upon the valid issuance of the Conversion Shares credited as paid up in full upon the conversions pursuant to this Section 4, whether or not this Note has been surrendered and whether or not all share subscription, shareholders’ agreement, or other agreements have been executed and delivered by the Holder to the Company.
