SUBSCRIPTION FOR UNITS

| TO: | ProMIS Neurosciences Inc. (the “Corporation”)

The undersigned (the “Subscriber”, including, if applicable, each Disclosed Principal (as hereinafter defined) for whom the undersigned is acting hereunder) hereby irrevocably subscribes for and agrees to purchase the number of units of the Corporation (the “Units”) set forth below for the aggregate subscription amount set forth below (the “Aggregate Subscription Amount”), representing a subscription price of US$0.30 per Unit, on the terms and conditions set forth in “Terms and Conditions of Subscription for Units of ProMIS Neurosciences Inc.” attached hereto (together with the face pages and the attached Schedules, the “Subscription Agreement”). Each Unit consists of one common share of the Corporation (a “Common Share”) and one-half of a transferable share purchase warrant (a “Warrant”).

Each whole Warrant entitles the holder to purchase one Common Share (a “Warrant Share”) at any time for a five year period, subject to acceleration (as noted below), at a price of CDN$0.48 per Warrant 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 Common Shares on the TSX, and/or such other exchange on which the Common Shares may be listed, is greater than CDN$1.00 (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 shall be calculated by dividing the total value by the total volume of Common Shares traded (on all exchanges, including the TSX and such other exchange on which the Common Shares may be listed) for the twenty trading days immediately preceding the date of the Trigger Event.

The Units, the Common Shares, the Warrants and the Warrant Shares are hereinafter referred to together as the “Securities”.

SCHEDULE I

U.S. ACCREDITED INVESTOR CERTIFICATE

In connection with the purchase of Units of ProMIS Neurosciences Inc. (the “Corporation”) by the undersigned Subscriber, or if applicable, the principal on whose behalf the undersigned is purchasing as agent, the Subscriber and the Corporation agree that Unit Subscription Agreement is amended (I) to attach this Certificate thereto and (II) to the extent of any inconsistencies with the Unit Subscription Agreement, have the provisions of this Certificate prevail to the extent of any inconsistencies with the Unit Subscription Agreement.

For the purposes of this Certificate, a “U.S. Investor” is: (a) any person who is, or who is purchasing Units for the account of or benefit of, a U.S. Person or a person in the United States; (b) any person who was offered Units in the United States; or (c) any person who executed or delivered the Subscription Agreement to which this Certificate is attached in the United States. A “U.S. Person” has the meaning assigned in Rule 902(k) of Regulation S (“Regulation S”) under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), which definition includes: (a) any natural person resident in the United States; (b) any partnership or corporation organized or incorporated under the laws of the United States; (c) any trust of which any trustee is a U.S. Person; (d) any partnership or corporation organized outside the United States by a U.S. Person principally for the purpose of investing in securities not registered under the U.S. Securities Act, unless it is organized or incorporated, and owned, by accredited investors (within the meaning assigned in Rule 501(a) of Regulation D (“Regulation D”) under the U.S. Securities Act) who are not natural persons, estates or trusts; (e) any estate of which any executor or administrator is a U.S. person.

Capitalized terms not specifically defined in this Certificate will have the meaning ascribed to them in the Subscription Agreement to which this Certificate is attached.

The Subscriber covenants, represents and warrants to the Corporation that:

| (a) | it understands (A) that the Units, the underlying Common Shares and Warrants, and the Warrant Shares (together with the Common Shares and Warrants, the “Securities”), have not been and will not be registered under the U.S. Securities Act or the securities laws of any state of the United States; and (B) the offer and sale contemplated hereby is being made in reliance on an exemption from such registration requirements in reliance on Rule 506(b) of Regulation D under the U.S. Securities Act and/or Section 4(a)(2) of the U.S. Securities Act;

| (b) | it has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Units and it is able to bear the economic risk of loss of its entire investment;

| (c) | the Corporation has provided to it the opportunity to ask questions and receive answers concerning the terms and conditions of the Private Placement, and it has had access to such information concerning the Corporation (including access to the Corporation’s public filings available on the Internet at www.sedar.com) as it has considered necessary or appropriate in connection with its investment decision to acquire the Units, and that any answers to questions and any request for information have been complied with to the Subscriber’s satisfaction;

| (d) | it is acquiring the Units for its own account, or for the account of one or more persons for whom it is exercising sole investment discretion, (a “Beneficial Purchaser”), for investment purposes only and not with a view to resale or distribution and, in particular, neither it nor any Beneficial Purchaser for whose account it is purchasing the Units has any intention to distribute either directly or indirectly the Securities in the United States or to, or for the account or benefit of, a U.S. Person or person in the United States; provided, however, that this paragraph shall not restrict the Subscriber from selling or otherwise disposing of such Securities pursuant to registration thereof pursuant to the U.S. Securities Act and any applicable state securities laws, or under an exemption from such registration requirements;

15

| (e) | the address of the Subscriber set out on the front page of the Subscription Agreement is the true and correct principal address of the Subscriber and can be relied on by the Corporation for the purposes of state blue-sky laws and the Subscriber has not been formed for the specific purpose of purchasing the Units;

| (f) | it has not purchased the Units as a result of any form of general solicitation or general advertising (as those terms are used in Regulation D), including advertisements, articles, press releases, notices or other communications published in any newspaper, magazine or similar media or on the Internet, or broadcast over radio or television, or the Internet or other form of telecommunications, including electronic display, or any seminar or meeting whose attendees have been invited by general solicitation or general advertising;

| (g) | it acknowledges that the Securities are “restricted securities”, as such term is defined in Rule 144(a)(3) under the U.S. Securities Act, and may not be offered, sold, pledged, or otherwise transferred, directly or indirectly, without prior registration under the U.S. Securities Act and applicable state securities laws, and it agrees that if it decides to offer, sell, pledge or otherwise transfer, directly or indirectly, any of the Securities absent such registration, it will not offer, sell, pledge or otherwise transfer, directly or indirectly, such Securities, directly or indirectly, except (i) to the Corporation, (ii) outside the United States in an “offshore transaction” meeting the requirements of Rule 904 of Regulation S under the U.S. Securities Act, if available, and in compliance with applicable local laws and regulations, (iii) in compliance with the exemption from the registration requirements under the U.S. Securities Act provided by Rule 144 thereunder, if available, and in accordance with any applicable state securities or “blue sky” laws, or (iv) in a transaction that does not require registration under the U.S. Securities Act or any applicable state laws and regulations governing the offer and sale of securities, and, in the case of each of (iii) and (iv) it has prior to such sale furnished to the Corporation an opinion of counsel in form and substance reasonably satisfactory to the Corporation stating that such transaction is exempt from registration under applicable securities laws and that the legend referred to in paragraph (h) below may be removed.

| (h) | it acknowledges that the certifcates (or DRS) representing the Common Shares and Warrant Shares, as well as all certifcates (or DRS) issued in exchange therefor or in substitution thereof, until such time as is no longer required under the applicable requirements of the U.S. Securities Act or applicable state securities laws, will bear, on the face of such certifcate (or DRS), the following legend:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE COMPANY THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, DIRECTLY OR INDIRECTLY, ONLY (A) TO THE COMPANY; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH ALL LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSE (C) OR (D), THE SELLER FURNISHES TO THE COMPANY AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY TO SUCH EFFECT.

16

THE PRESENCE OF THIS LEGEND MAY IMPAIR THE ABILITY OF THE HOLDER HEREOF TO EFFECT “GOOD DELIVERY” OF THE SECURITIES REPRESENTED HEREBY ON A CANADIAN STOCK EXCHANGE.”

provided, that if the Common Share or the Warrant Shares are being sold outside the United States in compliance with the requirements of Rule 904 of Regulation S and such Securities were issued at a time when the Corporation qualifies as a “foreign issuer” (as defined in Regulation S), the legend set forth above may be removed by providing a declaration to the registrar and transfer agent of the Corporation, as set forth in Appendix “A” attached hereto (or in such other form as the Corporation may prescribe from time to time); and provided, further, that, if the Common Shares or Warrant Shares are being sold otherwise than in accordance with Rule 904 of Regulation S and other than to the Corporation, the legend may be removed by delivery to the registrar and transfer agent and the Corporation of an opinion of counsel of recognized standing in form and substance satisfactory to the Corporation that such legends are no longer required under applicable requirements of the U.S. Securities Act or state securities laws;

| (i) | it understands and acknowledges that the Corporation is not obligated to remain a “foreign issuer” within the meaning of Regulation S;

| (j) | it acknowledges that the certificates representing Warrants, as well as all certificates issued in exchange therefor or in substitution thereof, until such time as is no longer required under the applicable requirements of the U.S. Securities Act or applicable state securities laws, will bear, on the face of such certifcate (or DRS), the following legend:

“THE WARRANTS REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON EXERCISE THEREOF HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE COMPANY THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, DIRECTLY OR INDIRECTLY, ONLY (A) TO THE COMPANY; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH ALL LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSE (C) OR (D), THE SELLER FURNISHES TO THE COMPANY AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY TO SUCH EFFECT.

THE WARRANTS REPRESENTED HEREBY MAY NOT BE EXERCISED BY OR ON BEHALF OF A U.S. PERSON OR A PERSON IN THE UNITED STATES UNLESS THE SECURITIES ISSUABLE UPON EXERCISE OF THE WARRANTS HAVE BEEN REGISTERED UNDER THE U.S. SECURITIES ACT AND THE APPLICABLE SECURITIES LEGISLATION OF ANY SUCH STATE OR EXEMPTIONS FROM SUCH REGISTRATION REQUIREMENTS ARE AVAILABLE. “UNITED STATES” AND “U.S. PERSON” ARE AS DEFINED BY REGULATION S UNDER THE U.S. SECURITIES ACT.”

| (k) | it understands and acknowledges that (A) if the Corporation is deemed to have been at any time previously an issuer with no or nominal operations and no or nominal assets other than cash and cash equivalents, Rule 144 under the U.S. Securities Act may not be available for resales of the Securities, and (B) the Corporation is not obligated to make Rule 144 under the U.S. Securities Act available for resales of such Securities;

17

| (l) | it understands and agrees that there may be material tax consequences to the Subscriber of an acquisition, disposition or exercise of any of the Securities. The Corporation gives no opinion and makes no representation with respect to the tax consequences to the Subscriber under United States, state, local or foreign tax law of the undersigned’s acquisition or disposition of such Securities. In particular, no determination has been made whether the Corporation will be a “passive foreign investment company” within the meaning of Section 1297 of the United States Internal Revenue Code of 1986, as amended;

| (m) | it understands and agrees that the financial statements of the Corporation have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and therefore may be materially different from financial statements prepared in accordance with U.S. generally accepted accounting principles and may not be comparable to financial statements of United States companies;

| (n) | it consents to the Corporation making a notation on its records or giving instruction to the registrar and transfer agent of the Corporation in order to implement the restrictions on transfer set forth and described herein;

| (o) | it understands and acknowledges that the Corporation is incorporated outside the United States, consequently, it may be difficult to provide service of process on the Corporation and it may be difficult to enforce any judgment against the Corporation;

| (p) | it understands that the Corporation does not have any obligation to register the Securities under the U.S. Securities Act or any applicable state securities laws or to take action so as to permit resales of the Securities. Accordingly, the Subscriber understands that absent registration, the Subscriber may be required to hold the Securities indefinitely. As a consequence, the Subscriber understands that it must bear the economic risks of the investment in the Securities for an indefinite period of time; and

| (q) | it, and if applicable, each Beneficial Purchaser for whose account it is purchasing the Units, is an “accredited investor” as defined in Rule 501(a) of Regulation D by virtue of satisfying one or more of the categories indicated below (please hand-write your initial on the appropriate lines and write “SUB” for the criteria the Subscriber meets and “BEN” for the criteria any persons for whose account or benefit the Subscriber is purchasing the Shares meets):
