		1.	General Terms

 

MoonLake Immunotherapeutics AG is
a stock corporation duly organized according to art. 620 ss. of the Swiss Code of Obligation and domiciled in Zug, Switzerland.

 

With the present Participation Plan,
the Company creates an instrument to enable eligible Employees and Members of the Board to participate in the Company at favourable conditions.

 

The purpose of this Participation
Plan is to attract and retain the best available personnel and to provide Participants with additional incentive to increase their efforts
on behalf and in the best interest of the Company and its subsidiaries. The Participation Plan is intended to accomplish these goals
by enabling the Company to grant Shares.

 

This Participation Plan sets forth
the general rules and conditions of the grant of such Shares, whereas the individual Allocation Agreements entered into by the Company
and the Participants will contain the specifically agreed terms and conditions of a Share grant.

 

The terms of this Participation Plan
apply upon the acquisition of Shares by eligible Employees and Members of the Board as of the implementation by the Board until the Board
decides in its own discretion to terminate this Participation Plan.

                                            Plan in accordance with Section 12.
	 	 	 

All decisions, determinations and interpretations of the Administrator regarding the
Participation Plan shall be final and binding for the Eligible Persons and the Participants.

article 4 of the Articles of Association, as amended from time to time. Article 4 currently provides for a conditional increase of the
share capital of a maximum of CHF 6,000.00 by the issuance of a maximum of 60,000 Shares with a nominal value of CHF 0.10 each. The Participation
Plan may furthermore be funded through treasury shares within the meaning of art. 659 of the Swiss Code of Obligations.

 

		6.	Right to Participate

 

The Administrator shall select the
Employees and the Members of the Board who are eligible to participate under this Participation Plan at its sole discretion. It being
understood that the Administrator might decide that no one shall be eligible in one or several relevant year(s).

 

The Administrator shall also determine
at its sole discretion about:

                                            specific Eligible Person;
	 	 	 

		b)	the Grant Date;
	 	 	 

		c)	the offered purchase price of the Shares
                                            (it being understood that the Shares may also be granted free of charge or in lieu of salary
                                            payments);
	 	 	 

		d)	as well as all other parameters of
                                            the offered Shares;

of this Participation Plan.

 

    8

     

    

 

The participation right of the Eligible
Person is personal and non-transferable.

 

Neither the establishment of this
Participation Plan, nor the eligibility to participate, nor the granting of Shares hereunder, nor any (other) action of the Company or
the Administrator in connection with this Participation Plan does create any right to any (further) participation or continued employment
or mandate of the Company. The election as an Eligible Person as well as the granting of any rights or payments under this Participation
Plan is on a voluntary basis, which does not create any right of future participation. Even repeated grants without the reservation of
voluntariness shall not create any legal claim for the Eligible Persons and the Participants, neither in respect to their cause nor their
amount nor for the past nor for the future.

 

		7.	Grant and acquisition of Shares

 

The grant of Shares to a Participant
under this Participation Plan and the respective terms and conditions thereof shall be evidenced by an Allocation Agreement, substantially
in the form of Annex 1 or such other form as the Administrator may determine from time to time, duly signed by the Company and
the Participant.

 

The Administrator shall inform the
Eligible Person about the number of offered Shares and the purchase price per Share by sending an Allocation Agreement to the Eligible
Person. Simultaneously, the Administrator shall determine and inform the Eligible Person about the deadline until when the Eligible Person
might accept the offer.

 

By returning, the duly completed
and duly signed Allocation Agreement to the Company within the deadline set by the Administrator, the Eligible Person irrevocably accepts
the grant of the offered Shares (to the extent indicated in the Allocation Agreement) according to the terms and conditions set out in
the Allocation Agreement and this Participation Plan.

 

In particular, by returning the duly
completed and duly signed Allocation Agreement the Participant undertakes to pay the purchase price and to acquire the indicated number
of Shares at the Grant Date.

 

The transfer of title takes place
at the Grant Date determined by the Administrator if the conditions precedent of grant set out in Section 8 are met.

 

By signing the Allocation Agreement,
the Participant entitles the Company to register the Participant as the owner of the acquired Shares into the shareholders’ register
of the Company.

 

    9

     

    

 

No Eligible Person shall have any
right or claim under this Participation Plan, unless he/she has specifically been granted Shares based on a counter-signed Allocation
Agreement and has thus become a Participant. The promise to grant Shares, or the attribution of Shares in any document other than in
an Allocation Agreement shall not be considered as a valid grant of Shares until it is formalized in an Allocation Agreement pursuant
to this Participation Plan.

 

As of the date of signing the Allocation
Agreement by the Participant, the terms and provisions of this Participation Plan form an integral part of the employment or director
relationship of the Participant with the Company.

 

		8.	Conditions Precedent regarding the Transfer of TItle

 

Full legal title in the respective
Shares (including voting and dividend rights) shall transfer to the Participant at the Grant Date, subject to the fulfilment of the following
conditions precedent and unless otherwise agreed upon in the Allocation Agreement or the Participation Plan:

 

		a)	the Participant’s Contractual
                                            Relationship is not being terminated at the Grant Date; and
	 	 	 

		b)	the Participant has signed the form
                                            of accession to the then current Employee Shareholders’ Agreement as Employee Shareholder
                                            (as defined in the Employee Shareholders’ Agreement), substantially in the form of
                                            Annex 2, as amended from time to time.

 

	9.	Reverse Vesting
	 	 

		9.1	Vesting Schedule

 

100% of the Shares granted to a Participant
under this Participation Plan shall be considered unvested at the Grant Date and, therefore, be subject to a reverse vesting and respective
call option (the «Leaver Call Options») as further set forth in this Section 9 (the «Leaver Shares»).

shall (reverse) vest over a period of 4 years (the «Vesting Period») as follows (the «Vesting Schedule»):

                                            Date, 25% of the Shares shall vest, whereas fractions of Shares shall be rounded down to
                                            the next full number;
	 	 	 

		b)	on the second anniversary of the Grant
                                            Date, 25% of the Shares shall vest, whereas fractions of Shares shall be rounded down to
                                            the next full number;

 

    10

                                            Date, 25% of the Shares shall vest, whereas fractions of Shares shall be rounded down to
                                            the next full number;
	 	 	 

		d)	on the fourth and last anniversary of
                                            the Grant Date, all Options shall fully vest.

 

If a Participant, after the Grant
Date, ceases to provide services to the Company due to sickness, accident, parental leave or any other voluntary or involuntary leave
of absence, vesting of unvested shares shall be put on hold 90 calendar days after the beginning of such a leave of absence. The vesting
shall continue when the Participant resumes his/her services to the Company.

 

If a Participant reduces his/her
workload by more than 30% compared to the workload on the Grant Date, the Vesting Schedule for unvested shares shall be extended proportionately.

 

Upon the occurrence of a Change of
Control, the Administrator shall notify the Participant (the “Change of Control Notice”) that all Shares which have
not vested by virtue of the Vesting Schedule agreed upon in the Allocation Agreement, shall continue to vest in accordance with the Vesting
Schedule except that any and all unvested Shares shall be deemed fully vested at the earlier of (the “Accelerated Vesting Date”):

 

		a)	12 months (or such shorter period determined
                                            by the Board in the Change of Control Notice) after the occurrence of a Change of Control;
                                            or
	 	 	 

		b)	the date after the occurrence of the Change
                                            of Control on which a termination notice is served in relation to the relevant Contractual
                                            Relationship with the Company or its subsidiaries by the Company or the subsidiary for any
                                            reason that would not qualify the Participant as a Bad Leaver or by the Participant for good
                                            cause within the meaning of article 337 of the Swiss Code of Obligations or article 337 of
                                            the Swiss Code of Obligations by analogy (or an equivalent provision under any applicable

they have already vested or not, at nominal value.

 

		9.3	Exercise of Leaver Call Options

 

In the event of a termination of the
employment relationship, if the Company, or any third party designated by it, wishes to exercise the Leaver Call Options, the Company,
or the third party designated by it, shall notify the relevant Participant (or, as the case may be, their legal successor, receiver,
insolvency judge or any other person with the right to act on behalf of the relevant Shareholder or their estate) within 30 calendar
days of the effective date of the termination and state in such notice the number of Leaver Shares that the Company, or the third party

		10.1	General Restrictions

 

Any Shares acquired under this Participation
Plan are subject to such transfer restrictions as set forth in this Participation Plan, the Articles of Association, the Employee Shareholders’
Agreement, the applicable securities law provisions and by the Board.

 

    12

     

    

 

The Shares granted under this Participation
Plan will be delivered into a blocked custody account with the Company or a designated third party, unless the Administrator orders otherwise.

 

No Participant shall, except with
the prior written consent of the Board and subject to the Drag-Along and Tag-Along Rights (as defined in the Employee Shareholders’
Agreement) and the Leaver Call Options, transfer Leaver Shares during the Vesting Period.

 

No Participant shall
pledge, hypothecate, assign by way of security or otherwise create any lien, encumbrances, charges or third party right on any Shares
or any right granted under this Participation Plan. The Shares shall remain free and clear of any liens, encumbrances, charges or any
other third party rights.

 

		10.2	Right of First Refusal of the Company

 

Each Participant hereby grants to
the Company, or to any third party designated by it, a right of first refusal with respect to the Shares granted under this Participation
Plan in the event such Participant wishes to transfer all or a part of such vested Shares to a third party (including another shareholder
of the Company) (the “Right of First Refusal”).

 

In such a case, the Participant shall
submit to the Company (i) an offer stating the price and terms of the proposed transfer (including the identity of the proposed acquirer
(if any) and (ii) a copy of such offer (if any) (the “Right of First Refusal Notice”). The price and terms of the

The transfer of the relevant Shares
shall be consummated within 60 calendar days from receipt of the Right of First Refusal Notice.

 

In the event the Right of First Refusal
is not exercised or not exercised for all relevant offered Shares, the Participant shall be free, subject to further restrictions as
may apply under the Employee Shareholders’ Agreement, the Articles of Association, this Participation Plan or any other arrangement,
to transfer the relevant Shares to the proposed acquirer, on terms not more favorable than those offered to the Company in the Right
of First Refusal Notice, within a period of three months after expiry of the 30 calendar day period to submit a Right of First Refusal
Exercise Notice. Thereafter, the procedure pursuant to this Section 10.2 shall be repeated prior to any such transfer.

 

    13

     

    

 

		11.	Taxation and Social Security

 

Any social security and similar contributions
legally due on the allocation of Shares granted hereunder or on any other realization of income derived from the Shares are shared accordingly
to the applicable laws and agreements between the Company and such Participants. To the extent the Company has paid the Participant’s
share of such contribution, the Participant shall upon demand reimburse the Company the amount so paid. The Company reserves the right
to withhold parts of the Participant’s ordinary salary or other remuneration (including Shares issuable or transferable under this
Participation Plan) to pay any employee’s contributions to social security, taxes or other duties, if financial means are not provided
by the Participant otherwise.

 

The Company shall disclose any taxable
income derived under this Participation Plan in the salary statement (Lohnausweis) as far as the Company is aware of such income,
and shall deduct the relevant source tax, if any.

 

To enable the Company to fully disclose
any taxable income derived under this Participation Plan, the Participant undertakes to immediately inform the Company about any realization
of income derived from the Options or the Shares, which the Company might not be aware of. Such duty includes (among others) to inform
the Company about any sale of Shares and about the terms and conditions thereof (including the purchase price).

 

It is the Participant’s responsibility
to adhere to, declare and pay all income, wealth or other taxes incurring by reason of his/her participation in this Participation Plan,
according to the tax laws of any state or country in which he/she has a tax obligation. The Company is not responsible for any consequences
of incorrect tax declarations.

 

Any stamp duties and other costs
directly related to the issuance and delivery of the Shares, if any, payable by the Company shall be borne by the Company.

 

		12.	Effective Date / Amendment and Termination of the Plan

 

The Participation Plan has been approved
by the Board and became effective with the approval of the Board.

 

The Administrator may at any time
make amendments and modifications to this Participation Plan as it deems advisable, in its sole discretion, including those amendments
that may be necessary or desirable to comply with or conform to applicable tax laws. Furthermore, the Administrator is entitled to terminate
this Plan at any time.

 

    14

     

    

 

The Administrator may issue other
employee participation plans, in replacement of this Participation Plan or in parallel to this Participation Plan, at any time and in
its sole discretion. It may offer Participants to transfer on a replacement plan even before expiry of this Participation Plan and under
such conditions as deemed equitable by the Company.

 

By signing the Allocation Agreement,
the Participant confers power of attorney to any individual member of the Administrator to sign, issue, execute, make and perform on
behalf of the Participant such powers, documents, instruments, certificates or acts that seem useful to the proxy in connection with
a possible going public of the Company on a recognized securities exchange.

 

Notwithstanding the foregoing, no
such amendment shall impair any of the granted rights of any Participant with respect to any Shares granted before.

in Zug, Switzerland.

 

With
the present Participation Plan, the Company creates an instrument to enable eligible Employees and Members of the Board to participate

intended to accomplish these goals by enabling the Company to grant Options to acquire Shares.

 

This
Participation Plan sets forth the general rules and conditions of the grant and exercise of such Options, whereas the individual Allocation
Agreements entered into by the Company and the Participants will contain the specifically agreed terms and conditions of an Option grant.

 

The
terms of this Participation Plan apply upon the acquisition of Options by eligible Employees and Members of the Board as of the implementation
by the Board until the Board decides in its own discretion to terminate this Participation Plan.

 

		2	Interpretations

present Participation Plan is only applicable in its entirety. Neither the eligible person nor third parties might derive any rights

The

or continued employment or mandate of the Company. The election as an Eligible Person as well as the granting of any rights or payments
under this Participation Plan is on a voluntary basis, which does not create any right of future participation. Even repeated grants
without the reservation of voluntariness shall not create any legal claim for the Eligible Persons and the Participants, neither in respect
to their cause nor their amount nor for the past nor for the future.

If
a Change of Control occurs or is, in the reasonable opinion of the Administrator, expected to occur shortly, the Administrator shall
notify the Participant (the “Change of Control Notice”) that all Options which have – as per the date of the
Change of Control Notice – not vested by virtue of the Vesting Schedule agreed upon in the Allocation Agreement, shall continue

		b)	the
                                            date after the occurrence of the Change of Control on which a termination notice is served
                                            in relation to the relevant Contractual Relationship with the Company or its subsidiaries
                                            by the Company or the subsidiary for any reason that would not qualify the Participant as
                                            a Bad Leaver or by the Participant for good cause within the meaning of article 337 of the
                                            Swiss Code of Obligations or article 337 of the Swiss Code of Obligations by analogy (or
                                            an equivalent provision under any applicable foreign law).

 

Any
Options that vest on the Accelerated Vesting Date shall be exercisable within 10 calendar days from such date. Failure to exercise such
Options within this period shall automatically result in the forfeiture of such Options and the Company shall have no further obligation
with respect thereto.

                                            Notice

exercised to the bank account designated by the Company or, in case the Company has agreed to offset the Exercise Price against claims

Upon
and subject to the receipt of the payment or the confirmation of the offsetting, the Administrator shall ensure the proper issuance or
transfer of the relevant number of Shares to the Participant without undue delay and register the Participant as owner of the relevant
Shares with voting rights in the share register of the Company.

 

Should
the Participant fail to make the relevant payment and/or deliver the confirmation regarding offsetting within such time, the exercise
of the Options shall be deemed null and void and the Options shall be deemed forfeited unless otherwise determined by the Board at its
absolute discretion.

realization of income derived from the Options or the Shares are shared accordingly to the applicable laws and agreements between the
Company and such Participants. To the extent the Company has paid the Participant's share of such contribution, the Participant shall
upon demand reimburse the Company the amount so paid. The Company reserves the right to withhold parts of the Participant’s ordinary
salary or other remuneration (including Shares issuable or transferable under this Participation Plan) to pay any employee’s contributions

                                            against future dilutive effects (e.g. issuance of new Shares of the Company);

		b)	that
                                            since the Options and Shares are currently not listed on any stock exchange or traded on
                                            any regular market the Options and the Shares are illiquid in nature and the Participant

                                            the business and/or the value of the Company and its Shares;

		d)	that
                                            the investment is a venture capital investment and the risk of total loss of value regarding
                                            the Shares cannot be excluded.
