During the Standstill Period, the Purchaser shall, and shall cause each of its Controlled Affiliates to, (a) be present in person or represented by proxy at all meetings of shareholders of the Company so that all voting securities of the Company as to which they are entitled to vote shall be counted as present for the purpose of determining the presence of a quorum at such meeting, provided that, if the Purchaser or Controlled Affiliate is represented by proxy, the Purchaser or Controlled Affiliate shall designate a third party to act as such proxy who is not a member of the Company’s supervisory board, the Company’s management board, or is an officer or employee of the Company; and (b) vote with respect to all voting securities of the Company as to which each is entitled to vote and not to abstain from any vote.

5.5 Securities Law Disclosure; Publicity.

Following execution and delivery of this Agreement, the Company and the Purchaser shall issue a joint press release substantially in the form set forth in Exhibit B.

5.11 Registration Rights. The Company covenants and agrees as follows:

(a) On June 1, 2017, or such earlier time as the Company in its sole discretion may agree in writing, or such later time as the Purchaser in its sole discretion may agree in writing, the Company shall file a registration statement to register the resale of the Registrable Shares on a Form F-3 registration statement (or such other form appropriate for such purpose if the Company does not meet the eligibility requirements for use of Form F-3) under the Securities Act and use reasonable best efforts to have such registration statement declared effective and maintain the effectiveness of such registration statement for a period ending on the date the Purchaser no longer holds Registrable Shares.

(b) All expenses, other than Selling Expenses (as defined below), incurred in connection with registrations, filings or qualifications pursuant to this Section 5.11, including all registration, filing and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees and disbursements, shall be borne and paid by the Company. All Selling Expenses shall be borne by the Purchaser; or if there are other selling shareholders with shares being registered pursuant to such registration statement, then pro rata by the selling shareholders based on the number of shares sold by such selling shareholder in the offering.

(c) For the purposes of this Section 5.11,

(i) “Losses” means any loss, damage, claim or liability (joint or several) to which a party hereto may become subject under the Securities Act, the Exchange Act, or other federal or state law, insofar as such loss, damage, claim or liability arises out of and is based upon: (A) any untrue statement or alleged untrue statement of a material fact contained in any registration statement of the Company registering the resale of the Registrable Shares, including any preliminary prospectus or final prospectus contained therein or any

Confidential Treatment Requested Under 17 C.F.R.§§ 200.80(b)(4) and 240-24b-2

amendments or supplements thereto or (B) an omission or alleged omission to state in such registration statement a material fact required to be stated therein, or necessary to make the statements therein not misleading.

(ii) “Registrable Shares” means the Shares held by Purchaser including, without limitation, any Common Shares paid, issued or distributed in respect of any such Shares by way of stock dividend, stock split or distribution, or in connection with a combination of shares, recapitalization, reorganization, merger or consolidation, or otherwise, but excluding Common Shares acquired in the open market before or after the date hereof, provided, however, that the Shares will not be “Registrable Shares” (A) after the Shares have been sold pursuant to an effective registration statement or in compliance with Rule 144, (B) when the remaining Shares held by the Purchaser could, in the opinion of counsel satisfactory to the Company, be sold by the Purchaser in a single transaction under the terms of this Agreement and the volume and manner of sale limitations under Rule 144, or (C) upon such time as the registration statement registering the resale of the Registrable Shares has been effective for forty two (42) months following the Lock-up Expiration Date (regardless of whether such months are consecutive).

(iii) “Selling Expenses” means the fees and disbursements of counsel for the Purchaser.

(d) With a view to making available to the Purchaser the benefits of Rule 144, during the twelve (12) month period following the expiration of the Lock-Up Period, the Company covenants that it will use commercially reasonable efforts to (i) file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder and (ii) make available information necessary to comply with Rule 144 with respect to resales of the Shares under the Securities Act, at all times, to the extent required from time to time to enable the Purchaser to resell Shares without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144 (if available with respect to resales of the Shares), as such rule may be amended from time to time or (B) any other rules or regulations now existing or hereafter adopted by the SEC.

(e) To the extent permitted by law, the Company will indemnify and hold harmless the Purchaser, and the partners, members, officers and directors of the Purchaser and each Person, if any, who controls the Purchaser (collectively, “Purchaser Indemnified Parties”), against any Losses, and the Company will pay to the Purchaser Indemnified Parties any legal or other reasonable and documented expenses incurred thereby in connection with investigating or defending any claim or proceeding from which Losses may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 5.11(e) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable for any Losses to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any Purchaser Indemnified Party expressly for use in connection with such registration.

Confidential Treatment Requested Under 17 C.F.R.§§ 200.80(b)(4) and 240-24b-2

(f) Promptly after receipt by the Purchaser under this Section 5.11 of notice of the commencement of any action (including any governmental action) for which a Purchaser Indemnified Party may be entitled to indemnification hereunder, the Purchaser Indemnified Party will, if a claim in respect thereof is to be made against the Company under this Section 5.11, give the Company notice of the commencement thereof. The Company shall have the right to participate in such action and, to the extent the Company so desires, and to assume the defense thereof with counsel mutually satisfactory to the Purchaser Indemnified Parties; provided, however, that the Purchaser Indemnified Parties shall have the right to retain one separate counsel for all such Purchaser Indemnified Parties, with the reasonable and documented fees and expenses to be paid by the Company, if representation of the Purchaser by the counsel retained by the Company would be inappropriate due to actual or potential conflict of interest between the Purchaser Indemnified Parties and the Company. The failure to give notice to the Company within a reasonable time of the commencement of any such action shall relieve the Company of any liability to the Purchaser Indemnified Parties under this Section 5.11, only to the extent that such failure materially prejudices the Company’s ability to defend such action. The failure to give notice to the Company will not relieve it of any liability that it may have to the Purchaser otherwise than under this Section 5.11.

(g) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which contribution under the Securities Act may be required on the part of the Purchaser Indemnified Parties, then such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of the Company and each Purchaser Indemnified Party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the Company and each Purchaser Indemnified Party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the Company or by a Purchaser Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (x) the Purchaser will not be required to contribute any amount in excess of the public offering price of all such Registrable Shares offered and sold by the Purchaser pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

5.12 Participation in Future Financing.

(a) Subject to compliance with applicable securities laws, until the earlier of (i) such time as the Purchaser Transfers more than [*] of the Shares and (ii) termination of the Standstill Period, upon any issuance of Common Shares by the Company in a private

Confidential Treatment Requested Under 17 C.F.R.§§ 200.80(b)(4) and 240-24b-2

placement to institutional investors for cash consideration (a “Subsequent Financing”), the Company agrees at least [*] Trading Days prior to the closing of the Subsequent Financing, to deliver to the Purchaser written notice of its intention to effect a Subsequent Financing (the “Subsequent Financing Notice”). The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected. Upon receipt of the Subsequent Financing Notice, the Company and the Purchaser shall in good faith discuss the Purchaser’s participation in the Subsequent Financing up to the Purchaser’s Pro-Rata Share (as defined below) on the same terms, conditions and price provided for in the Subsequent Financing. For purposes of this Agreement, the Purchaser’s “Pro-Rata Share” shall be equal to the number of Common Shares deemed to be beneficially owned by the Purchaser immediately prior to the date of the Subsequent Financing Notice (based upon documentation or written representation reasonably satisfactory to the Company), divided by the total number of Common Shares outstanding (including any Common Shares issuable upon conversion or exercise of outstanding Common Share Equivalents deemed to be beneficially owned by the Purchaser and included in the numerator of its pre-Subsequent Financing Notice beneficial ownership calculation) immediately prior to the closing of the Subsequent Financing.

(b) If the Purchaser desires to participate in such Subsequent Financing, the Purchaser must provide written notice to the Company, by not later than 5:30 p.m. (New York City time) on the [*] Trading Day after the Purchaser has received the Subsequent Financing Notice (the “Participation Deadline”), that the Purchaser is willing to participate in the Subsequent Financing and stating the amount of the Purchaser’s elected participation, but in no event shall such amount of Common Shares that would cause the Purchaser to exceed its Pro-Rata Share. If the Company receives no such notice from the Purchaser as of the Participation Deadline, the Purchaser shall be deemed to have notified the Company that it does not elect to participate in the Subsequent Financing.

(c) Notwithstanding anything to the contrary in this Section 5.12, it is understood and agreed that: (i) the foregoing agreement to engage in good faith discussions with respect to a Subsequent Financing only applies in the event of a private placement with institutional investors (i.e., not a public offering or in connection with a strategic transaction) and (ii) the Company will neither be obligated to include the Purchaser as an investor in any such private placement nor will the Purchaser be obligated to invest in any such private placement.

(d) If, by the [*] day following delivery of the Subsequent Financing Notice, no public disclosure regarding a transaction with respect to the Subsequent Financing has been made, such Subsequent Financing shall be deemed to have been abandoned and the Purchaser shall not be in possession of any material, non-public information with respect to the Company, unless the Company advises the Purchaser that the Subsequent Financing has not been abandoned. The Company understands and confirms that the Purchaser may rely on this Section 5.12(d) when effecting transactions in securities of the Company.

5.13 PFIC Reporting. For so long as the Purchaser holds Shares, the Company hereby agrees to reasonably cooperate with the Purchaser in order to permit the Purchaser to determine whether the Company is at any time a “passive foreign investment company” (as defined in Section 1297(a) of the Code) (a “PFIC”). In furtherance of the foregoing, the Company shall notify the Purchaser if, in good faith, the Company reasonably believes the Company or any of its controlled Subsidiaries was a PFIC during the prior taxable year. If the Company determines that the Company or any of its controlled subsidiaries is a PFIC, the Company shall (i) promptly after such determination notify the Purchaser, (ii) timely provide such information to the Purchaser as the Purchaser may reasonably request to enable the Purchaser to complete its U.S. Internal Revenue Service Form 8621 with respect to such entity and (iii) use reasonable efforts to provide such statements, information and documentation as the Purchaser reasonably believes is necessary for it to make an election to treat such subsidiary as a “qualified electing fund” under Section 1295 of the Code.

5.14 Controlled Foreign Corporation. For so long as the Purchaser is a “United States shareholder” within the meaning of Section §951(b) of the Code (a “10% U.S. Shareholder”) of the Company at any point during a taxable year, then the Company hereby agrees to reasonably cooperate with the Purchaser in order to permit the Purchaser to determine whether the Company is a “controlled foreign corporation” within the meaning of Section 957 of the Code (a “CFC”). If the Company is or is likely to have become a CFC, then the Company shall use reasonable efforts to provide to the Purchaser such information as it may reasonably request to assist the Purchaser to timely comply with its filing obligations under the Code, including but not limited to Internal Revenue Service Form 5471.

Upon such determination that any provision of this Agreement, or the application of any such provision, is invalid, illegal, void or unenforceable, the Company and the Purchaser shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Company and the Purchaser as closely as possible to the fullest extent permitted by Law in an acceptable manner to the end that the transactions contemplated hereby and the other Transaction Agreements are fulfilled to the greatest extent possible.

Subject to review of documents and opinion committee approval - for discussion purposes only -

Personal and confidential

To: the Purchaser (as defined in the Share Subscription

Agreement (as defined below))

19 December 2016 -

Subject to review of documents and opinion committee approval - for discussion purposes only -

Dear Sir/Madam,

We have acted as counsel as to matters of Netherlands law to Merus N.V., a public company incorporated under the laws of the Netherlands having its registered office (statutaire zetel) in Utrecht, the Netherlands and its principal place of business at Yalelaan 62,3584 CM Utrecht, the Netherlands (the “Company”) in connection with the offering by the Company of […] common shares with a nominal value of EUR 0.09 per share (the “Offer Shares”), pursuant to a share subscription agreement, dated […] between the Company as company and, inter alios, [...] as purchaser (hereinafter the “Purchaser”) (the “Share Subscription Agreement”) and a collaboration agreement, dated […], between the Company and the Purchaser (the “Collaboration Agreement”).

This opinion is rendered to you upon your request in connection with the Share Subscription Agreement and the Collaboration Agreement.

In rendering this opinion letter, we have solely examined and relied upon the documents as specified in Annex 1. Any attachments thereto and documents mentioned or referred to therein are excluded for the purpose of this opinion letter except to the extent explicitly stated otherwise in Annex 1.

We have only expressed opinions on matters of the laws of the European territory of the Kingdom of the Netherlands (“the Netherlands”) as they currently stand and as they have been published as at the date of this opinion letter. We have made no investigations into the laws of any other jurisdiction as a basis for the opinions as expressed herein, and we do not express or imply any opinion on such jurisdictions.

Furthermore, for the purpose of this opinion letter, we have not expressed an opinion on Dutch tax law, European law (unless directly applicable in the Netherlands), international law, competition law and/or anti-trust law. This includes (without limitation) the (i) rules and/or (ii) promulgated rules of or by any bilateral or multilateral treaty or treaty organisation, unless implemented under the laws of the Netherlands. Finally, no opinion

LOGO

Subject to review of documents and opinion committee approval - for discussion purposes only -

has been expressed on any commercial, accounting or other non-legal matter or on the ability as a matter of fact (as opposed to law) of the Company to meet its financial obligations or any other obligation under the Opinion Documents.

We have not been concerned with investigating or verifying the accuracy of any fact, representation or warranty as set out or as referred to in the Opinion Documents, with the exception of those matters on which we have specifically expressed our opinions. To the extent that the accuracy of such facts, representations or warranties not so investigated or verified and any of the facts stated in the Opinion Documents is relevant to this opinion letter, we have assumed, with your permission, that such facts, representations and warranties are true and correct.

The opinions as rendered in this opinion letter have been given on the basis of, and are subject to (i) the assumptions set out in Annex 2 and (ii) the qualifications set out in Annex 3. The opinions given in this opinion letter are strictly limited to the matters set out in paragraphs 1 up to and including 19 below.

Annex 1, Annex 2 and Annex 3 (together hereinafter the “Annexes”) form an integral part of this opinion letter. This opinion letter cannot be read and/or interpreted without the Annexes.

We are of the opinion that:

Corporate Status

1.	The Company is validly existing under the laws of the Netherlands as a ‘naamloze vennootschap’ (a public company with limited liability).

Corporate Power

2.	The Company has the corporate power (i) to execute the Opinion Documents and (ii) to perform its obligations thereunder, including the issuance of the Offer Shares and excluding pre-emption rights with respect to the Offer Shares.

Corporate Action

The Company has taken all corporate actions required under its Articles of Association, its Rules and/or the laws of the Netherlands to authorize the execution of the Deed of Issue of Shares, the Share Subscription Agreement, the issuance of the Offer Shares and excluding pre-emption rights with respect to the Offer Shares.

Valid Execution

4.	The Opinion Documents have been validly executed on behalf of the Company.

Share Capital

5.	The Offer Shares have been duly authorised and duly issued.

6.	Upon payment in full by the Purchaser for the Offer Shares in accordance with the terms of Share Subscription Agreement, the Offer Shares have been fully paid.

7.	Any statutory pre-emptive rights and pre-emptive rights under the Articles of Association relating to the issue of the Offer Shares have been validly excluded.

LOGO

Subject to review of documents and opinion committee approval - for discussion purposes only -

Enforceability of Obligations

8.	The obligations expressed to be assumed by the Company in the Deed of Issue of Shares are legal, valid and binding obligations of the Company, enforceable against it in the Netherlands in accordance with their terms.

No Authorisations, Consents or Approvals

There are no governmental or regulatory consents, approvals or authorisations required under the laws of the Netherlands or by any authority of the Netherlands for (i) the Company’s authorization, entry into and performance of the Opinion Documents and (ii) the offering or issuance of the Offer Shares.

No Violation of Law

10.	The issuance of the Offer Shares by or on behalf of the Company does not conflict with or does not result in a breach of any provision of the laws of the Netherlands or the Articles of Association.

No Registration, Filing or similar Formalities

11.	Under the laws of the Netherlands there are no registration, filing or similar formalities required of the Company to ensure the admissibility in evidence, validity, binding effect and enforceability against the Company of the Share Subscription Agreement and the Collaboration Agreement. ¹

Exchange Control Restrictions

12.

There are no exchange control restrictions in the Netherlands which would prevent the Company from paying dividends to shareholders in U.S. Dollars or any other currency and no approvals are required from governmental, judicial or public bodies or authorities in the Netherlands in order for the Company to pay dividends.

No Immunity

13.	Neither the Company nor any of its assets is entitled to immunity from any legal proceedings in the Netherlands in order to enforce the Opinion Documents or any liability or obligation of the Company arising thereunder.

Choice of Law

14.

The courts of the Netherlands will generally give effect to the choice of the laws of the State of New York as the governing law of the Share Subscription Agreement and, where it pertains to the Dutch Law Matters as defined in the Share Subscription Agreement, to the choice of the laws of the Netherlands.

15.	The courts of the Netherlands will generally give effect to the choice of the laws of the State of New York as the governing law of the Collaboration Agreement.

¹	Please note that the share issuance needs to be registered in the Company’s shareholders register.

Subject to review of documents and opinion committee approval - for discussion purposes only -

Submission to Jurisdiction

16.

The submission by the Company in the Share Subscription Agreement and the Collaboration Agreement to the exclusive jurisdiction of the United States District Court for the Southern District of New York United States is valid and binding on the Company. Such submission does not preclude that claims for provisional measures in summary proceedings may be brought before a competent Dutch court.

Enforcement of Judgments

17.

There is no enforcement treaty between the Netherlands and the United States. Consequently, a judgment of a court sitting in the United States District Court for the Southern District of New York cannot automatically be enforced in the Netherlands. In order to obtain a judgment in respect of the Share Subscription Agreement and the Collaboration Agreement that can be enforced in the Netherlands against the Company, the dispute will have to be re-litigated before a Netherlands court of competent jurisdiction. This court will have discretion to attach such weight to the judgment of the court sitting in the United States District Court for the Southern District of New York as it deems appropriate. Given the submission by the Company to the jurisdiction of the courts sitting in the United States District Court for the Southern District of New York, the Netherlands courts can be expected to give conclusive effect to a final and enforceable judgment of such court in respect of the contractual obligations under the Share Subscription Agreement and the Collaboration Agreement without re-examination or re-litigation of the substantive matters adjudicated upon. This would require that (i) proper service of process has been given, (ii) the proceedings before the court sitting in the United States District Court for the Southern District of New York having complied with principles of proper procedure (behoorlijke rechtspleging), and (iii) such judgment not being contrary to the public policy of the Netherlands.

Carry on Business

18.	In order to enable the Purchaser to enforce its rights under the Opinion Documents, it is not necessary under the laws of the Netherlands that it should be licensed, qualified or otherwise entitled to carry on business in the Netherlands.

Limited Liability Shareholder

19.

Under Dutch law, the liability of a holder of shares is limited to the payment of the nominal value of the shares increased with the share premium as may be agreed between such holder and the Company and a holder of shares will have no personal liability for the debts and obligations of a Dutch company solely by reason of the holding of such shares in a Dutch company.

The opinions reflected above express and describe Dutch legal concepts in English and not in their original Dutch terms. Consequently, the opinions reflected above are issued and may only be relied upon on the express condition that they shall be governed by (and that all words and expressions used herein shall be construed and interpreted in accordance with) the laws of the Netherlands.

This opinion letter is strictly limited to the matters set forth herein, and no opinion may be inferred or implied beyond those expressly stated herein.

ANNEX 3

The opinions in this opinion letter are subject to the following qualifications:

A.	under the laws of the Netherlands:

effect may be given to the law of another jurisdiction with which the situation has a close connection, insofar as, under the law of that jurisdiction, that law is mandatory irrespective of the governing law of the Share Subscription Agreement and the Collaboration Agreement;

the laws of the Netherlands will be applied insofar as it is mandatory irrespective of the governing law of the Share Subscription Agreement and the Collaboration Agreement;

the application of the laws of the State of New York may be refused if it is manifestly incompatible with Dutch public policy; and

account will be given to the laws of the jurisdiction in which performance takes place in relation to the manner of performance and the steps to be taken in the event of defective performance;

this opinion letter is subject to any limitations arising from bankruptcy (faillissement), insolvency, fraudulent preference (pauliana), liquidation, suspension of payments (surseance van betaling), reorganisation and other laws of general application relating to or affecting the rights of creditors sanctions and measures, including but not limited to those concerning export control, pursuant to European Union regulations, under the Sanctions Act 1977 (Sanctiewet 1977) or any other legislation;

the Excerpt does not provide conclusive evidence that the facts set out therein are correct; however, under the Trade Register Act 2007 (Handelsregisterwet 2007) subject to limited exceptions, the Company cannot invoke the incorrectness or incompleteness of the trade register registration against third parties who were unaware of such incorrectness or incompleteness;

D.	the confirmation from the bankruptcy clerk’s office referred to in paragraph (iv) of Annex 2 does not provide conclusive evidence that the Company has not been declared bankrupt or granted a suspension of payments;

pursuant to (i) article 2:7 DCC as it relates to the Company, any transaction entered into by a legal entity may be nullified by the legal entity itself or its receiver in bankruptcy (curator) if the objects of that entity were transgressed by the transaction and the other party to the transaction knew or should have known this without independent investigation (wist of zonder eigen onderzoek moest weten). The Netherlands Supreme Court (Hoge Raad der Nederlanden) has ruled that in determining whether the objects of a legal entity are transgressed, not only the description of the objects in that legal entity’s articles of association (statuten) is decisive, but all (relevant) circumstances must be taken into account, in particular whether the interests of the legal entity were served by the transaction;

F.	a power of attorney granted by a Dutch company will automatically (i.e. by operation of law) terminate upon the bankruptcy of such company or become ineffective when such company has been granted a suspension of payments;

•

Collaboration designed to leverage Merus’ Biclonics^® bispecific antibody technology to expand Incyte’s discovery capabilities and large-molecule portfolio

•

Incyte to make up-front payment of $120 million and purchase $80 million of Merus common shares; Merus eligible to receive potential development, regulatory and commercial milestones and sales royalties

WILMINGTON, DE AND UTRECHT, THE NETHERLANDS, December 21, 2016 –

Incyte Corporation (NASDAQ:INCY) and Merus N.V. (NASDAQ:MRUS) announced today that they have entered into a global, strategic collaboration agreement focused on the research, discovery and development of bispecific antibodies utilizing Merus’ proprietary Biclonics^® technology platform. The Collaboration and License Agreement grants Incyte the exclusive rights for up to eleven bispecific antibody research programs, including two of Merus’ current preclinical immuno-oncology discovery programs.

Biclonics^® retain the IgG format of antibodies that are produced naturally by the immune system and, by binding to two targets, enable multiple modes of action that cannot otherwise be obtained with conventional monoclonal antibodies.

“By virtue of a unique ability to simultaneously engage multiple protein targets, we believe bispecific antibodies have the potential to play an important role in the future of biotherapeutics,” said Reid Huber, Ph.D., Incyte’s Chief Scientific Officer. “This collaboration with Merus expands our large molecule discovery capabilities into an innovation-rich area of research, creating additional opportunities for us to deliver on our commitment to improving and extending the lives of patients with cancer and other serious diseases.”

“This transformative, global collaboration further underscores the potential of Merus’ Biclonics^® technology platform and establishes a strong relationship with Incyte, a leader in innovative drug development,” said Ton Logtenberg, Ph.D., Chief Executive Officer of Merus. “We look forward to expanding our pipeline under this agreement, as we efficiently exploit our preclinical discovery engine and progress our most advanced, proprietary assets in the clinic.”

Terms of the Collaboration

Under the terms of the collaboration, Incyte has agreed to pay Merus an upfront payment of $120 million. In addition, Incyte has agreed to purchase 3.2 million shares of Merus stock at $25 per share, for a total equity investment of $80 million.

The parties have agreed to collaborate on the development and commercialization of up to 11 bispecific antibody programs. For one current preclinical program, Merus will retain all rights to develop and commercialize approved products in the United States, and Incyte will develop and commercialize approved products arising from the program outside the United States. Following any regulatory approval of a product candidate for this particular pre-clinical program, each company has agreed to pay the other tiered royalties ranging from 6 to 10 percent on net sales of products in their respective territories.

Merus also has the option to co-fund development of product candidates arising from two other programs. For any program for which Merus exercises its co-development option, Merus would be responsible for 35 percent of global development costs in exchange for a 50 percent share of U.S. profits and losses and tiered royalties ranging from 6 to 10 percent on ex-U.S. sales by Incyte for these programs. Merus also has the right to elect to provide up to 50 percent of detailing activities for product candidates arising from one of these programs in the United States.

For each of the other eight programs, Incyte has agreed to independently fund all development and commercialization activities. For these programs, Merus will be eligible to receive potential development, regulatory and sales milestone payments of up to $350 million per program, which could result in an aggregate milestone opportunity of approximately $2.8 billion if all development, regulatory and sales milestones are achieved across all such eight other programs in all territories. Merus will also be eligible to receive tiered royalties ranging from 6 to 10 percent on global sales of any approved products under these eight programs.

Merus will retain the rights to its technology platform as well as clinical and pre-clinical candidates and future programs emerging from Merus’ platform that are outside the scope of this agreement.

The transaction is expected to close in the first quarter of 2017, subject to the early termination or expiration of any applicable waiting periods under the Hart-Scott Rodino Act and customary closing conditions.

Merus will retain rights to both of its clinical candidates and MCLA-158, as well as any future programs emerging from Merus’ platform that are outside the scope of the agreement.
