Settlement Agreement, dated April 16, 2020, between Mark Throsby

Merus N.V., a public limited liability company (in Dutch: naamloze vennootschap), incorporated under the laws of the Netherlands, having its statutory seat at Utrecht, the Netherlands, registered with the Dutch Trade Register with number 30189136 (the Company);

Mr. Mark Throsby, born in Adelaide on 22 March 1967, residing Bredeweg 40-2 Amsterdam, 1098 BS (“Mr. Throsby”);

Mr. Throsby entered into an Employment Agreement with the Company on 1 October 2008 (dated 19 July 2008), and an Additional Employment Agreement with the Company dated 10 March 2010 (collectively, the Employment Agreement).

The Company has taken the initiative to come to a termination of the Employment Agreement. This initiative is not based on urgent grounds within the meaning of article 7:678 of the Dutch Civil Code (in Dutch: Burgerlijk Wetboek) (DCC).

The Company and Mr. Throsby have agreed to the termination of the Employment Agreement by mutual consent (in Dutch: wederzijds goedvinden).

In view of the above, the Parties have entered into discussions on the terms and conditions of an amicable settlement on the termination of the Employment Agreement as well as any other issues there may be and wish to lay down the settlement in this settlement agreement (this Agreement).

Mr. Throsby has obtained legal advice from a lawyer on the content of this Agreement and the consequences thereof.

By means of this Agreement - which is considered to be a settlement agreement within the meaning of article 7:900 et seq. of the Dutch Civil Code (the DCC) - the Parties wish to record and lay down what they exhaustively and comprehensively have established and agreed in respect of the termination of the Employment Agreement, with a view to end and prevent any uncertainty or dispute between them as to what applies between them by law, whereby the Parties waive any and all claims and agreements against each other, which might exist or might have existed.

Termination of Employment Agreement

Duties

Mr. Throsby shall continue to perform his duties as directed by the Chief Executive Officer primarily in the effort to develop therapies for the COVID-19 pandemic and in evaluating, pursuing and promoting licensing and collaboration opportunities concerning the Company’s or third party company’s technology, preclinical and clinical assets to the best of his abilities in a loyal, diligent and professional manner until the Termination Date, or as otherwise instructed by the Company. In addition, Mr. Throsby shall be available to, if so requested, assist the Company concerning a proper handover of tasks and knowledge.

Mr. Throsby resigns as Chief Scientific Officer and from any and all other functions he holds on behalf of the Company and its affiliated companies effective as of the Termination Date.

Compensation

Until the Termination Date, Mr. Throsby shall be paid his regular salary, including standard benefits.

As a compensation for the termination of the Employment Agreement, including the termination of all functions Mr. Throsby holds on behalf of the Company and its affiliated companies, the Company shall pay Mr. Throsby an amount equal to EUR 269913.26 gross (“Severance Payment”) constituting a total amount of eight months’ severance and amortized bonus of four months based on the 2019 bonus award, and inclusive of holiday allowance.

The compensation referred to in clause 3.2 shall be paid, under withholding of the required wage tax and social premiums (if any), one (1) month after the Termination Date, by wire transfer to the salary account of Mr. Throsby as known to the Company.

The Company shall draw up a final statement of indebtedness (in Dutch: eindafrekening) in connection with the termination of the Employment Agreement. The final statement shall include Mr. Throsby's accrued pro rata holiday allowance and the balance of outstanding holidays at the Termination Date, which shall be paid out.

Mr. Throsby acknowledges that the payments and benefits set forth in clause 3.2 of this Agreement represent settlement in full of all payments and benefits owed to Mr. Throsby by the Company in connection with the termination of Mr. Throsby’s employment with the

Company and Mr. Throsby shall not be entitled to any additional notice period or continued payment of his base salary for whatever reason, including, but not limited to any possible entitlement to a transitional remuneration (in Dutch: transitievergoeding) as defined in article 7:673 of the Dutch Civil Code which is considered to be covered in the Severance Payment. Mr. Throsby shall receive no other wages, bonus, severance or any other payments or benefits from Merus following the Termination Date.

Subject to Mr. Throsby’s continued compliance with the terms and conditions of this Agreement, including clause 5, Mr. Throsby’s unvested equity awards granted to him under the applicable equity-based long-term incentive plan of the Company (LTIP) will continue to vest under the LTIP until October 31, 2020 as if Mr. Throsby had continued in full time service with the Company through such date and will be further dealt with and settled according to the terms and conditions of the relevant applicable LTIP scheme. In no event shall Mr. Throsby be eligible to vest in any portion of the LTIP following
October 31, 2020. In addition, the post-termination exercise period of Mr. Throsby’s options to purchase common shares of the Company as set out in the relevant applicable LTIP will not commence until December 31, 2020, and shall expire on March 31, 2021.

For the avoidance of doubt, the Parties acknowledge that Mr. Throsby shall not be entitled to any other benefits, compensation, incentive plans or other type of payments, than those explicitly mentioned and provided for in this Agreement. As of the Termination Date, Mr. Throsby is no longer entitled to and shall not receive any salary (including benefits) anymore.

Insurances & pension

At the Termination Date, all insurances and/or schemes in which Mr. Throsby participates under his Employment Agreement shall terminate and cease to be effective, with the exception of the run-off period of any applicable liability insurance taken out by the Company for the benefit of its officers.

Mr. Throsby's pension will be settled in accordance with the rules of the pension scheme and pension legislation.

Restrictive Covenants

The applicable confidentiality clause as referred to in clause 12 of the Employment Agreement, the relationship clause as referred to in clause 13 of the Employment Agreement and the rights and obligations with respect to intellectual property as referred to in the Additional Employment Agreement including the penalty clauses stated therein will remain in full force, also after the Termination Date.

Clause 14 (prohibition on secondary employment) of the Employment Agreement will remain in force until the Termination Date.

Mr. Throsby shall observe confidentiality with respect to all information, know-how and data relating to the Company and its affiliates that is confidential and shall not use any of such information, know-how and data.

Mr. Throsby confirms that he has no intellectual property rights related to the business of the Company and its affiliates.

In consideration for the portion of the consideration provided under this Agreement to which Mr. Throsby is not otherwise entitled, and in order to protect the value of any confidential information of the Company to which Mr. Throsby was provided access during his employment with the Company, Mr. Throsby agrees that, from the date hereof and during the 12 (twelve) month period following the Termination Date, Mr. Throsby will not, directly or indirectly, on Mr. Throsby's own behalf or for the benefit of any other individual or entity: (a) operate, conduct, engage in or own (except as the holder of not more than 1% of the outstanding stock of a publicly-held company), or prepare to operate, conduct, engage in or own any business or enterprise that develops, manufactures, markets, licenses, sells or otherwise provides, or is preparing to develop, manufacture, market, license, sell or otherwise provide any product or service that relates to bispecific, trispecific or other multispecific antibody therapeutics and competes with any product or service developed, manufactured, marketed, licensed, sold or otherwise provided, or planned to be developed, manufactured, marketed, licensed, sold or otherwise provided, by the Company or any of its subsidiaries while Mr. Throsby was providing services to the Company (the Competing Business) or (b) participate in, render services to, or assist any individual or entity that engages in a Competing Business in any capacity (whether as an employee, manager, consultant, Mr. Throsby, officer, contractor, or otherwise) (A) which involve the same or similar types of services Mr. Throsby performed for the Company at any time during the last two years of his services to or engagement with the Company or (B) in which Mr. Throsby could reasonably be expected to use or disclose proprietary information of the Company or any of its subsidiaries, in each case (a) and (b) limited to each city, county, state, territory and country in which (x) Mr. Throsby provided services or had a material presence or influence at any time during the last two years of Mr. Throsby's services to or engagement with the Company or (y) the Company or any of its subsidiaries is engaged in or has plans to engage in the Competing Business as of the date hereof.  

From the date hereof and during the 12 (twelve) month period following the Termination Date (the Nonsolicitation Restricted Period), Mr. Throsby will not, directly or indirectly, on Mr. Throsby's own behalf or for the benefit of any other individual or entity: (i) solicit, encourage, induce or attempt to induce or assist others to solicit, encourage, induce or attempt to induce any employees, consultants or independent contractors of the Company or any of its subsidiaries to terminate their employment or other engagement with the Company or any of its subsidiaries; (ii) hire, or recruit or attempt to hire, or engage or attempt to engage as an independent contractor, any person who was employed or otherwise engaged by the Company or any of its subsidiaries at any time during the term of Mr. Throsby's employment with the Company; provided, that this clause (ii) shall not apply to the recruitment or hiring or other

engagement of any individual whose employment or other engagement with the Company or any of its subsidiaries has been terminated for a period of six months or longer; (iii) solicit, divert or take away, or attempt to divert or take away, the business of any customer or client of the Company or any of its subsidiaries (served by the Company or any of its subsidiaries during the 12-month period prior to the termination of Mr. Throsby's services to the Company); or (iv) cause or encourage any vendor or supplier to reduce or cease doing business with the Company or any of its subsidiaries. Without limiting the Company's ability to seek other remedies available in law or equity, if Mr. Throsby violates any of the provisions of this clause 5.6, the Nonsolicitation Restricted Period shall be extended by one day for each day that Mr. Throsby is in violation of such provisions, up to a maximum extension equal to the length of the Nonsolicitation Restricted Period, so as to give the Company the full benefit of the bargained-for length of forbearance.

If any provision of clause under this clause 5 shall be determined to be unenforceable by any court of competent jurisdiction or arbitrator by reason of its extending for too great a period of time or over too large a geographic area or over too great a range of activities, it shall be interpreted to extend only over the maximum period of time, geographic area or range of activities as to which it may be enforceable.
