In the absence of such a designation, upon the death of

the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the Option and receive the Shares or other consideration resulting from such exercise.

all Options (including, for the avoidance of doubt, Vested Options) held by the Participant shall be immediately forfeited without value.

Article 13

TRANSFER / LEAVE OF ABSENCE

13.1 A change in the capacity in which the Participant renders service to the Company or a Subsidiary as an Employee, Director or Consultant or a change in the entity for which the Participant renders such service, will not cause the Participant to cease to be an eligible participant provided that there is no interruption or termination of the Participant’s service with the Company or a Subsidiary.

Article 14

NO (CONTINUED) EMPLOYMENT OR CONTRACTUAL RELATIONSHIP

14.1 Neither the establishment of the Plan, nor the granting of Options, nor the payment of any benefits, nor any action of the Company, the Board of Directors or a Subsidiary shall be held or construed to confer upon any Participant any legal right to continue to be employed by the Company or any of its Subsidiaries or to remain in a contractual relationship with said, each of which expressly reserves the right to discharge any Employee or Director whenever the interest of any such company in its sole discretion may so require without liability to such company or to the Board of Directors, except as to any rights which may be expressly conferred upon such Participant under the Plan.

ADDENDUM FOR U.S. PARTICIPANTS

1. Purpose and Applicability.

(a) This Addendum for U.S. Participants (the “U.S. Addendum”) applies to participants in the Plan who are either U.S. residents or U.S. taxpayers (each such participant, a “U.S. Participant”). The purpose of the U.S. Addendum is to facilitate compliance with U.S. tax, securities and other applicable laws, and to permit the Company to issue Options to eligible U.S. Participants.

(b) Except as otherwise provided by the U.S. Addendum, all Option grants made to U.S. Participants will be governed by the terms of the Plan, when read together with the U.S. Addendum. In any case of an irreconcilable contradiction (as determined by the Board of Directors) between the provisions of the U.S. Addendum and the Plan, the provisions of the U.S. Addendum will govern.

2. Definitions.

Capitalized terms contained herein have the same meanings given to them in the Plan, unless otherwise provided by the U.S. Addendum. In the U.S. Addendum, the following words will have the meaning as defined below:

“Code” means the U.S. Internal Revenue Code of 1986, as amended.

“Fair Market Value” means as of any date, the value of the Shares determined by the Board of Directors in compliance with Section 409A of the Code and, in the case of an Incentive Stock Option, in compliance with Section 422 of the Code.

“Incentive Stock Option” or “ISO” means a stock option that is intended to be, and qualifies as, an incentive stock option within the meaning of Section 422 of the Code.

“Nonstatutory Stock Option” or “NSO” means a stock option that does not qualify as an Incentive Stock Option.

“Plan” means Addex Therapeutics Ltd Share Option Plan.

“Securities Act” means the U.S. Securities Act of 1933, as amended.

“U.S.” means the United States of America.

3. Additional Terms and Conditions Applicable to All Options Granted to U.S. Participants.

(a) Form of Grant Notice. The Grant Notice for U.S. Participants shall be in substantially the form attached as Schedule 1 to the U.S. Addendum, as may be amended from time to time by the Board of Directors. The Grant Notice shall indicate if all or a portion of the Option is designated as an Incentive Stock Option.

(b) Exercise Price. Subject to the provisions of Section 4(d) below regarding Incentive Stock Options granted to certain major stockholders, the exercise price of each Option will be not less than one hundred percent (100%) of the Fair Market Value of the Shares subject to the Option on the date the Option is granted.

(c) Domestic Relations Orders. Subject to the approval of the Board of Directors or a duly authorized officer of the Company, an Option may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b) (2). If an Option is an Incentive Stock Option, such Option will be deemed to be a Nonstatutory Stock Option as a result of such transfer.

4. Provisions Applicable to Incentive Stock Options.

(a) Eligible Recipients of ISOs. Incentive Stock Options may be granted only to Employees.

(b) Designation of ISO Status. The Board of Directors action approving the grant of an Option to a U.S. Participant, and the Grant Notice, must specify that the Option is intended to be an Incentive Stock Option. If an Option is not specifically designated as an Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option.

(c) Maximum Shares Issuable On Exercise of ISOs. Subject to the adjustment provisions of Section 16 of the Plan, the maximum aggregate number of Shares that may be issued upon the exercise of Incentive Stock Options is 10,557,419 Shares.

(d) Limits for 10% Stockholders. A person who owns (or is deemed to own pursuant to Section 424(d) of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any affiliate, will not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five (5) years from the date of grant.

(e) No Transfer. As provided by Section 422(b)(5) of the Code, an Incentive Stock Option will not be transferable except by will or by the laws of descent and distribution, and will be exercisable during the lifetime of the

U.S. Participant only by the U.S. Participant. If the Board of Directors elects to allow the transfer of an Option by a U.S. Participant that is designated as an Incentive Stock Option, such transferred Option will automatically become a Nonstatutory Stock Option.

(f) US $100,000 Limit. As provided by Section 422(d) of the Code and applicable regulations thereunder, to the extent that the aggregate Fair Market Value (determined at the time of grant) of Shares with respect to which Incentive Stock Options are exercisable for the first time by any U.S. Participant during any calendar year (under all plans of the Company and any Subsidiary) exceeds US$100,000 (or such other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Grant Agreement(s).

(g) Post-Termination Exercise Period. To obtain the U.S. federal income tax advantages associated with an Incentive Stock Option, the U.S. Internal Revenue Code requires that at all times beginning on the date of grant and ending on the day three (3) months before the date of exercise of the Option, the U.S. Participant must be an employee of the Company or a Subsidiary (except in the event of the U.S. Participant’s death or Disability, in which case a 12-month period applies)). The Company cannot guarantee that the Option will be treated as an Incentive Stock Option if the U.S. Participant continues to provide services to the Company or a Subsidiary after such U.S. Participant’s

employment terminates or if the U.S. Participant otherwise exercises the Option more than three (3) months (or twelve (12) months, as the case may be) after the date his or her employment terminates, or the Option otherwise fails to qualify as an Incentive Stock Option.

5. Tax Matters

(a) Tax Withholding Requirement. Prior to the delivery of any Shares pursuant to the exercise of an Option, the Company will have the power and the right to deduct or withhold, or require a U.S. Participant to remit to the Company, an amount sufficient to satisfy U.S. federal, state, local, foreign or other taxes (including the U.S. Participant’s FICA obligation) required to be withheld with respect to such Option.

(b) Withholding Arrangements. The Company may, in its sole discretion, satisfy any U.S. federal, state, local, foreign or other tax withholding obligation relating to an Option by any of the following means or by a combination of such means: (i) causing the U.S. Participant to tender a cash payment; (ii) withholding Shares issued or otherwise issuable to the U.S. Participant in connection with the Option; provided, however, that no Shares are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Option as a liability for financial accounting purposes); or (iii) withholding payment from any amounts otherwise payable to the U.S. Participant.

(c) No Obligation to Notify or Minimize Taxes. The Company will have no duty or obligation to the U.S. Participant to advise such holder as to the time or manner of exercising the Option. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Option or a possible period in which the Option may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Option to the U.S. Participant.

(d) Section 409A of the Code. Unless otherwise expressly provided for in an Grant Agreement, the terms applicable to Options granted under the U.S. Addendum will be interpreted to the greatest extent possible in a manner that makes the Options exempt from Section 409A of the Code, and, to the extent not so exempt, that brings the Options into compliance with Section 409A of the Code. Notwithstanding anything to the contrary in the Plan (and unless the Grant Agreement or other written contract with the U.S. Participant specifically provides otherwise), if the Shares are publicly traded, and if a U.S. Participant of an Option that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” under Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six (6) months following the date of such U.S. Participant’s “separation from service” or, if earlier, the date of the U.S. Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six (6) month period elapses, with the balance paid thereafter on the original schedule.

6. Term, Amendment and Termination of the U.S. Addendum.

(a) The Board of Directors may amend, suspend or terminate this U.S. Addendum at any time. Unless terminated sooner by the Board of Directors, the U.S. Addendum will terminate automatically upon the earlier of (i) 10 years after the Effective Date and (ii) the termination of the Plan. No Options may be granted under the U.S. Addendum while either the Plan or the U.S. Addendum is suspended or after the Plan or the U.S. Addendum is terminated.

(b) If this U.S. Addendum is terminated, the provisions of this U.S. Addendum and any administrative guidelines, and other rules adopted by the Board of Directors and in force at the time of

suspension or termination of this U.S. Addendum, will continue to apply to any outstanding Options as long as an Option issued pursuant to the U.S. Addendum remain outstanding.

(c) No amendment, suspension or termination of the U.S. Addendum may materially adversely affect any Options granted previously to any U.S. Participant without the consent of the U.S. Participant.

Additional Terms/Acknowledgements: The U.S. Participant acknowledges receipt of, and understands and agrees to, this Grant Notice, the U.S. Addendum and the Plan. The U.S. Participant acknowledges

(1) If this is an Incentive Stock Option, it (plus other outstanding Incentive Stock Options) cannot be first exercisable for more than $100,000 in value (measured by exercise price) in any calendar year. Any excess over $100,000 is a Nonstatutory Stock Option.

(2) Note to client — the vesting schedule can be customized; this typical provision is a placeholder.

and agrees that this Grant Notice, the U.S. Addendum and the Plan may not be modified, amended or revised except as provided in the Plan. The U.S. Participant further acknowledges that as of the Date of Grant, this Grant Notice, the U.S. Addendum and the Plan set forth the entire understanding between the U.S. Participant and the Company regarding the Options and supersede all prior oral and written agreements, promises and/or representations on that subject with the exception of (i) options previously granted and delivered to the U.S. Participant, (ii) any compensation recovery policy that is adopted by the Company or is otherwise required by applicable law and (iii) any written employment or severance arrangement that would provide for vesting acceleration of the Options upon the terms and conditions set forth therein.

By accepting the Options, the U.S. Participant consents to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

In addition, by accepting the Options, the U.S. Participant consents that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes the U.S. Participant’s tax liabilities. The U.S. Participant agrees that the U.S. Participant will not make any claim against the Company, or any of its officers, directors, employees or affiliates related to tax liabilities arising from the Option or other compensation. In particular, the U.S. Participant acknowledges that the Option is exempt from Section 409A of the Code only if the exercise price per share specified in this Grant Notice is at least equal to the “fair market value” per Share on the Date of Grant and there is no other impermissible deferral of compensation associated with the Option. Because the Shares are not traded on an established securities market, the Fair Market Value is determined by the Board of Directors. The U.S. Participant acknowledges that there is no guarantee that the Internal Revenue Service will agree with the valuation as determined by the Board.
