5.7.2 An Option may be exercised by an Optionee or by a third party authorised by the Optionee to exercise Options on behalf of, and for the account of the Optionee pursuant to a mandate agreement (lastgevingsovereenkomst) as described in article 8 of the Dutch Decree on Market Abuse (Besluit marktmisbruik Wft).

5.8 Insider trading

5.8.1 No Option may be exercised and no Shares acquired as a result of an excercise of Options may be sold if the Optionee would thereby act contrary to any applicable law or regulation, including the applicable financial laws on insider trading and including the Insider Trading Policy. This means among other things that, unless Options are exercised and/or Shares are sold as specified in Article 5.8.3, no transactions may occur when the Optionee is in possession of Inside Information (as defined in the Insider Trading Policy).

5.8.2 In any case, no Option may be exercised by an Optionee and no Shares acquired as a result of an excercise of Options may be sold by an Optionee in the following time periods:

(i) 60 days immediately preceding the earlier of (i) the preliminary announcement of the Company’s annual results, or (ii) the publication of the Company’s annual financial report, or, if shorter, the period from the relevant financial year end up to and including the time of such preliminary announcement or publication, as the case may be;

(ii) 21 days immediately preceding the announcement of the Company’s quarterly or half-yearly results, or, if shorter, the period from the relevant financial period end up to and including the time of such announcement, or the announcement of a dividend or interim dividend;

(iii) 30 days immediately preceding the first publication of a prospectus for a share issue, or, if shorter, the period from the decision making prior to the publication of a prospectus and the first publication of the prospectus; and

(iv) such other periods as the Company may announce.

5.8.3 The prohibition to exercise Options when an Optionee is in possession of Inside Information (as defined in the Insider Trading Policy) does not apply if (i) the Options are exercised pursuant to a mandate agreement as set out in Article 5.7.2 or (ii) if the Options are exercised on the expiration date or within a period of five business days prior to this date. This also applies to the sale of Shares acquired as a result of the exercise of the Options within aforementioned period, subject to the condition that - at least four months prior to the expiration date - the Optionee notifies the Company in writing of his intention to sell, or has given the Company an irrevocable power of attorney to sell.

5.9 Accelerated vesting

Notwithstanding the foregoing, Options shall vest and become immediately exercisable with respect to 100% of the Shares:

(i) upon the consummation of a Relevant Transaction; and

(ii) in the events specifically set out in the Option Agreement and/or the Optionees employment, management or service agreement, with the approval of the Board.

5.10 Method of exercise

5.10.1 An Option may be exercised by the delivery to the Company during the period in which such Option is exercisable of written notice of exercise in the form attached to the Option Agreement as Exhibit A and payment in full of the Exercise Price of such specific number of Shares in respect to which Options are exercised. Payment for the Shares with respect to which an Option is exercised may be made in cash (in electronic funds transfer) only.

5.10.2 Alternatively, Options may be exercised by way of written power of attorney enabling the Company to, on behalf of the Optionee, (authorize a third party to) sell the Shares to which the Options pertain on the Exchange on the day on which the Option is exercised. Such power of attorney must be granted in the form of the power of attorney attached hereto as Exhibit 5.10.2. Upon the successful sale of such number of shares to which the Option pertains, the Company shall set off the proceeds of the sale against the Exercise Price of the Options and pay to the Optionee any excess proceeds (cashless exercise). The power of attorney granted pursuant to this Article 5.10.2 may also be granted on behalf of the Optionee by a third person pursuant to a mandate as described in Article 5.7.2.

6 Termination of employment or capacity

6.1 General

For purposes of this Article 6, an Optionee’s Termination occurs on the last day on which the Optionee performs services as a Key Person.

6.2 Termination for Cause: Options not vested and exercisable

Upon an Optionee’s termination of employment or capacity for Cause, all Options which were not exercised immediately before such termination of employment or capacity shall terminate, and no Option — also if vested — may be exercised after such termination of employment or capacity. Vested Options shall not terminate if such Options have been exercised and the respective Shares have not yet been issued to the Optionee.

6.3 Waiver by Board

Notwithstanding the foregoing provisions of this Article, the Board may in its sole discretion however in each case subject to the approval of the majority of the non- executive directors of the Board, as to all or part of any Options as to any Optionee, at the time the Option is granted or thereafter:

(i) determine that Options shall become exercisable or vested upon an Optionee’s Termination;

(ii) determine that after an Optionee’s Termination, such Optionee’s Options shall continue to become vested in accordance with the terms of the Plan and the individual Option Agreement;

(iii) determine that upon an Optionee’s Termination under certain circumstances, such Optionee’s Options shall vest (fully or partially) in deviation from the Plan; or

(iv) extend the period for exercise of Options following termination of employment or capacity (but not beyond 10 years from the Date of Grant).

6.4 Transferability of Options

The Options shall be strictly personal and no Option shall be transferable by the Optionee other than upon death (i) under the applicable laws of descent and distribution or (ii) by will. In connection herewith an Optionee may, by written instrument in a manner specified by the Board, designate in writing a beneficiary to exercise an Option after the death of the Optionee.

6.5 Transfer or pledge

No Option shall be assigned, negotiated or pledged in any way (whether by operation of law or otherwise) except as permitted by Article (iii), and no Option shall be subject to execution, attachment or similar process.

7 Amendments and termination

7.1 Amendment of the Plan

The Board may, however in each case subject to the prior written approval by the majority of the non-executive directors of the Board, amend, alter or discontinue the Plan, but no amendment, alteration, or discontinuation shall be made that would impair the rights of an Optionee under an Option theretofore granted without the Optionee’s consent except as required (i) to comply with securities, tax or other laws, (ii) to accomplish that the Plan shall remain or shall become tax-compliant and tax-efficient in the situation that the Company is replaced as a holding company by another company, including but not limited to a company under the laws of Belgium, or (iii) to ensure that the Plan is in conformity with market practice. Amendments or alterations to the Plan may only be made during a period when no Inside Information (as defined in the Insider Trading Policy) is available.

7.2 Amendment of Options

The Board may, however in each case subject to the approval of the majority of the non-executive directors of the Board, amend the terms of any Option theretofore granted, prospectively or retroactively, but no such amendment shall adversely affect the rights of any Optionee without the Optionee’s consent, except as required (i) to comply with securities, tax or other laws, (ii) to accomplish that the Plan shall remain or shall become tax-compliant and tax-efficient in the situation that the Company is replaced as a holding company by another company, including but not limited to a company under the laws of Belgium, or (iii) to ensure that the Option is in conformity with market practice. The Board may also substitute new Options for Options previously granted to Optionee’s, including previously-granted Options having higher Exercise Prices. Amendments or alterations to or substitutions of Options may only be made during a period when no Inside Information (as defined in the Insider Trading Policy) is available.

8 General provisions

8.3 No rights to employment

Nothing contained in the Plan or in any Option Agreement shall confer upon any Optionee any right with respect to continuance of employment by argenx Belgium, the Company or its Affiliates, nor interfere in any way with the right of argenx Belgium, the Company or its Affiliates to cause the Optionee’s Termination or change the Optionee’s compensation at any time.

8.4 Restructuring

In the event of any merger, reorganization, consolidation, recapitalization, stock dividend, stock split, spin-off or other change in corporate structure affecting the (underlying) Shares, such adjustment shall be made in the aggregate number and class of Shares which may be delivered under the Plan, in the number, class and Exercise Price, subject to outstanding Options granted under the Plan, and in the value, number or class of Shares subject to Options granted under the Plan as may be determined to be appropriate by the Board, in its sole discretion, however in each case subject to the approval of the majority of the non-executive directors of the Board, provided that the number of Shares subject to any Option shall always be a whole number.

8.5 Tax

All fiscal and social security consequences resulting from the Plan are at the expense of the Optionee.

All obligations of the Company, argenx Belgium, or another Affiliate, whichever the case may be, under the Plan shall be binding on any successor to the Company, argenx Belgium, or such other Affiliate.
