SPECIAL WARRANTS TERMS
OF
PROMIS NEUROSCIENCES INC.

1.                             The Holder acknowledges and agrees that each Special Warrant will automatically convert into one Share and one Warrant on the Conversion Date and no Special Warrants may be exercised by the holder thereof prior to the Conversion Date.

2.Each Warrant will entitle the holder to purchase one Share at any time for a period of sixty months, subject to acceleration (as noted below), at a price of $0.20 per share. At any time after the expiry of the four month hold period applicable to the Warrants, the Corporation may accelerate the expiry of the Warrants if the twenty-day volume-weighted average trading price of the Shares on the TSX (the “Exchange”), or such other exchange on which the Shares may be listed, is greater than $0.60 (the “Trigger Event”) provided that (a) the Corporation gives notice of the same in writing to the holder of the Warrants, and (b) the accelerated expiry date is a date which is not less than 30 calendar days after the date of such notice. For greater certainty, the twenty-day volume-weighted average trading price of the Common Shares on the Exchange shall be calculated by dividing the total value by the total volume of Common Shares traded on the Exchange for the twenty trading days immediately preceding the date of the Trigger Event.

3.After the deemed exercise of any of the Special Warrants represented by this Special Warrant Certificate, the Holder shall no longer have any rights this Special Warrant Certificate with respect to such Special Warrants, other than the right to receive certificates issuable on the exercise of those Special Warrants, and those Special Warrants shall be void and of no further value or effect.

4.The Special Warrants, the Shares and Warrants issuable upon the exercise of the Special Warrants, and any shares issuable upon the exercise of the Warrants, have not been and will not be registered under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), or under the securities laws of any state of the United States. The Special Warrants may not be exercised in the United States or by, or for the account or benefit of, any U.S. person or any person in the United States unless the Special Warrants, and the Shares and Warrants issuable upon exercise hereof, have been registered under the U.S. Securities Act and any applicable state securities laws or unless an exemption from such registration is available. “United States” and “U.S. person” are as defined in Rule 902 of Regulation S under the U.S. Securities Act.

5.The holding of the Special Warrants evidenced by this Special Warrant Certificate does not constitute the Holder a shareholder of the Corporation or entitle such holder to any right or interest in respect thereof except as expressly provided herein.

6.In any case where there is a capital reorganization (such as a share sub-division or consolidation or a transaction with an equivalent effect) or similar event (such as a merger) affecting the capital structure of the Corporation, the Corporation shall give notice to the Holder of the particulars of the event and, if determinable, the adjustment to the conversion terms of the Special Warrant to account for the event, such adjustment being subject to the approval of the Exchange. As a condition precedent to the taking of any action which would require an adjustment in any of the rights under the Special Warrant, the Corporation will provide the right to the Holder to convert the Special Warrants into the Shares and Warrants prior to the occurrence of the event. The Corporation shall use its best efforts to take any action which, in the opinion of the Corporation’s counsel, may be necessary in order that the Corporation, or any successor to the Corporation or successor to the undertaking or assets of the Corporation will be obligated to and may validly and legally issue all the Shares and Warrants or other securities of the Corporation, as applicable, pursuant to this Special Warrant Certificate to which the Holder would be entitled to receive thereafter and to exercise the Special Warrants in accordance with the provisions hereof.

7.                             The Special Warrants are not transferable without the prior written consent of the Corporation, and provided that, where such consent is obtained, such transfer is made in accordance with applicable securities laws and the Holder gives a 72 hour prior notice to the Corporation of such transfer by delivering a form of transfer in the form attached hereto as Schedule “B”.

8.Time shall be of the essence hereof.
