Subsection 3.2 of the Warrant Indenture is hereby to read as follows:

“Every ten (10) Warrants authorized to be issued hereunder shall entitle the registered holder thereof to acquire (subject to sections 3.13, 3.14 and 3.15) upon due exercise and upon the transaction instructions or due execution of the exercise form endorsed on the Warrant Certificate, as applicable, or other instrument of exercise in such form as the Warrant Agent and/or the Corporation may from time to time prescribe and upon payment of the Exercise Price, one Warrant Share or such other kind of amount of shares or securities or property, calculated pursuant to the provisions of sections 3.13 and 3.14, as the case may be, at any time after the date of issuance of such Warrants and prior to the Time of Expiry, in accordance with the provisions of this Indenture.”;

CUSIP ▇▇. ▇▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇. ▇▇▇▇▇▇▇▇▇▇▇▇

Warrant Certificate No. _______________

Representing _____________________ Warrants to purchase Common Shares

THIS CERTIFIES that, for value received, the registered holder hereof, ______________________ (the “holder”) is entitled, at any time at or before 5:00 p.m. (Montréal time) on July 20, 2026 (the “Time of Expiry”), to acquire, subject to adjustment in certain events, for every ten (10) Warrants represented hereby to purchase one fully-paid and non-accessible common share (a “Common Share”) of IMV Inc. (the “Corporation”), as presently constituted, by surrendering to Computershare Trust Company of Canada (the “Warrant Agent”) at its principal office in Montréal, Québec, and Toronto, Ontario this Warrant Certificate with the duly completed and executed Exercise Form endorsed on the back of this Warrant Certificate, and accompanied by payment of US$21.00 per Common Share (subject to adjustment in certain events) (the “Exercise Price”) by certified cheque, bank draft or money order in lawful money of the United States payable to, or to the order of, the Corporation at par at the above-mentioned office of the Warrant Agent.

The holder of this Warrant Certificate may purchase less than the number of Common Shares which he is entitled to purchase on the exercise of the Warrants represented by this Warrant Certificate, in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

The Warrants evidenced hereby are exercisable on or before the Time of Expiry, after which time the Warrants evidenced hereby shall be deemed to be void and of no further force or effect.

This Warrant Certificate represents Warrants of the Corporation issued or issuable under the provisions of a warrant indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated as of July 20, 2021, between the Corporation and the Warrant Agent, as supplemented by a first supplemental indenture dated December 8, 2022 between the Corporation and the Warrant Agent, as may be amended from time to time, which contains particulars of the rights of the holders of the Warrants and the Corporation and of the Warrant Agent in respect thereof and the terms and conditions upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available for inspection at the principal office of the Corporation in the City of Montréal, Québec. In the event of any conflict between the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant Indenture shall prevail.

A-2

Upon acceptance hereof, the holder hereof hereby expressly waives the right to receive any fractional Common Shares upon the exercise hereof in full or in part and further waives the right to receive any cash or other consideration in lieu thereof. The Warrants represented by this Warrant Certificate shall be deemed to have been surrendered, and payment by certified cheque, bank draft or money order shall be deemed to have been made only upon personal delivery thereof or, if sent by post or other means of transmission, upon actual receipt thereof by the Warrant Agent at its office in the City of Montréal, Québec and Toronto, Ontario.

Upon due exercise of the Warrants represented by this Warrant Certificate and payment of the Exercise Price, the Corporation shall cause to be issued to the person(s) in whose name(s) the Common Shares so subscribed for (provided that if the Common Shares are to be issued to a person other than the registered holder of this Warrant Certificate, the holder’s signature on the Exercise Form herein shall be guaranteed by a Schedule I Canadian chartered bank, or by a medallion signature guarantee from a member of a recognized Signature Medallion Guarantee Program and the holder shall pay to the Corporation or the Warrant Agent all applicable transfer or similar taxes and the Corporation shall not be required to issue or deliver certificates evidencing the Common Shares unless or until the holder shall have paid the Corporation or the Warrant Agent the amount of such tax (or shall have satisfied the Corporation that such tax has been paid or that no tax is due) are to be issued, the number of Common Shares to be issued to such person(s) and such person(s) shall become a holder in respect of such Common Shares with effect from the date of such exercise, and upon due surrender of this Warrant Certificate and all other documentation required, the Warrant Agent shall cause the issuance of a certificate(s) representing such Common Shares to be issued within two Business Days after the exercise of the Warrants (or portion thereof) represented hereby.

Pursuant to Section 4.2 of the Warrant Indenture, if at any time following the initial effectiveness of a shelf registration statement filed with the United States Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended, registering the Common Shares issuable upon exercise of the Warrants (a “Registration Statement”) and prior to the Time of Expiry, the Corporation determines that no Registration Statement filed with the United States Securities and Exchange Commission is effective, or the use of any such Registration Statement is suspended, no Warrantholder will be permitted to exercise Warrants unless an exemption or exclusion from the registration requirements of the U.S. Securities Act and applicable state securities laws is available, and the Corporation shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each holder of Warrants, and confirm in writing that the then outstanding Warrants may, until the earlier of (x) a Registration Statement becoming effective or ceasing to be suspended and any prospectus supplement necessary in relation thereto having been filed, or (y) the Time of Expiry, if the Current Market Price exceeds the Exercise Price, also be exercised by means of a “cashless exercise” in which the holder of Warrants shall be entitled to surrender a Warrant to the Corporation in exchange for the issuance of the number of Common Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: (a) (A) equals the Current Market Price on the trading day immediately preceding the date of the receipt by the Warrant Agent of the notice of exercise; (b) (B) equals the Exercise Price per Common Share of such Warrant, as adjusted; and (c) (X) equals the number of Common Shares that would otherwise be issuable upon exercise of such Warrant in accordance with its terms by means of a cash exercise rather than a cashless exercise.

A-3

The issue price for each such Common Share to be issued pursuant to the cashless exercise of a Warrant will be equal to (B), as defined above, and the total issue price for the aggregate number of Common Shares issued pursuant to the cashless exercise of a Warrant will be paid and satisfied in full by the surrender to the Corporation of such Warrant.

In addition, if the Corporation determines at any time prior to the Expiry Date that U.S. state securities laws are not preempted with respect to exercises of the Warrants, the Corporation may by written notice to the Warrant Agent elect to permit exercises of Warrants that are subject to the laws of one or more U.S. jurisdictions to be exercised on a “cashless exercise” basis, pursuant to the cashless exercise formula set forth above.

Upon the receipt of such notice, the Warrant Agent shall provide a copy thereof to each registered holder of Warrants, and confirm the Corporation’s determination in writing.

The holder acknowledges that the Warrants represented by this Warrant Certificate and the Common Shares issuable upon exercise hereof may be offered, sold or otherwise transferred only in compliance with all applicable securities laws.

No transfer of any Warrant will be valid unless entered on the register of transfers, upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, duly endorsed by, or accompanied by a transfer form or other written instrument of transfer in form satisfactory to the Warrant Agent executed by the registered holder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent. Subject to the provisions of the Warrant Indenture and upon compliance with the reasonable requirements of the Warrant Agent, Warrant Certificates may be exchanged for Warrant Certificates representing in the aggregate an equal number of Warrants. The Corporation and the Warrant Agent may treat the registered holder of this Warrant Certificate for all purposes as the absolute owner hereof. The holding of the Warrants represented by this Warrant Certificate shall not constitute the holder hereof a holder of Common Shares nor entitle him to any right or interest in respect thereof except as herein and in the Warrant Indenture expressly provided.

The Warrant Indenture provides for adjustment in the number of Common Shares to be delivered upon exercise of the right of purchase hereby granted and to the Exercise Price in certain events therein set forth.

The Warrant Indenture contains provisions making binding upon all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by the Warrantholders holding a specified percentage of the then outstanding Warrants.

The Warrants and the Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario and the federal laves of Canada applicable therein. Time shall be of the essence hereof and of the Warrant Indenture.

A-4

The Corporation may from time to time at any time prior to the Time of Expiry purchase any of the Warrants by private agreement or otherwise.

This Warrant Certificate shall not be valid for any purpose until it has been certified by or on behalf of the Warrant Agent for the time being under the Warrant Indenture.

All dollar amounts herein are expressed in the lawful money of the United States.

The signature below shall be deemed to constitute an original signature to this Warrant Certificate. This Warrant Certificate may be executed in one or more counter-parts, each of which may be delivered by facsimile, by e-mail in PDF, or other legally permissible electronic signature, and each of which will be deemed to be an original, and all of which together will be deemed to be one and the same document.
