ARYAU ARYA Sciences Acquistion Corporation

Business Combination Agreement

On March 17, 2020, ARYA Sciences Acquisition Corp., a Cayman Islands exempted company (“ARYA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among ARYA, Immatics B.V., a Netherlands private limited liability company (“TopCo”), Immatics Biotechnologies GmbH, a German limited liability company (“Immatics”), Immatics Merger Sub 1, a Cayman Islands exempted company (“ARYA Merger Sub”) and Immatics Merger Sub 2, a Cayman Islands exempted company (“IB Merger Sub”).

The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of ARYA and Immatics.

The Business Combination

The Business Combination Agreement provides for, among other things, the following transactions on the closing date (collectively, the “Business Combination”):

Business Combination Consideration

In accordance with the terms and subject to the conditions of the Business Combination Agreement, the consideration to be received by the shareholders of Immatics in connection with the transaction contemplated under the Business Combination Agreement shall be an aggregate number of TopCo Ordinary Shares equal to (a) $350,000,000 (subject to downward adjustments for certain changes in control costs as set forth in the Business Combination Agreement and assuming that all shareholders of Immatics have agreed to participate in the transaction), divided by (b) $10.00. In addition, the holders of Immatics stock appreciation rights may also be entitled to receive a portion of the transaction consideration otherwise payable to Immatics shareholders pursuant to the preceding sentence. Each ARYA shareholder will receive one TopCo Ordinary Share per ARYA ordinary share, as set forth above. Cash held in the trust account net of redemptions and the proceeds of the Private Placement (as defined below), less the transaction costs of the Business Combination, will be received by TopCo and used for general corporate purposes after the Business Combination.

Representations and Warranties; Covenants

Under the Business Combination Agreement, parties to the agreement made customary representations and warranties for transactions of this type regarding themselves. The representations and warranties made under the Business Combination Agreement shall not survive the closing of the Business Combination. In addition, the parties to the Transaction Agreement made covenants that are customary for transactions of this type.

Conditions to Each Party’s Obligations

Consummation of the transactions contemplated by the Business Combination Agreement is subject to customary conditions of the respective parties, and conditions customary to special purpose acquisition companies, including the approval of ARYA’s shareholders.

In addition, consummation of the transactions contemplated by the Business Combination Agreement is subject to other closing conditions, including, among others: (i) there has been no Company Material Adverse Effect (as defined in the Business Combination Agreement); (ii) the registration statement to be filed by TopCo has become effective; (iii) the Aggregate TopCo Transaction Proceeds (as defined in the Business Combination Agreement) shall be equal to or greater than $150,000,000; (iv) the proceeds from the Private Placement shall be equal to or greater than $100,000,000; and (v) in the case of ARYA’s obligation to close, the shareholders representing 92% of the issued and outstanding share of Immatics have agreed to participate in the transaction.

Termination

The Business Combination Agreement may be terminated under certain customary and limited circumstances at any time prior to the closing of the Business Combination, including (i) by either party, if the closing of the Business Combination has not occurred by October 10, 2020, unless the breach of any covenants or obligations under the Business Combination Agreement by the party seeking to terminate shall have proximately caused the failure to consummate the transactions contemplated by the Business Combination Agreement on or before such date and (ii) by either party, if ARYA’s shareholders do not approve the Business Combination at a meeting of ARYA’s shareholders. If the Business Combination Agreement is validly terminated, none of the parties to the Business Combination Agreement will have any liability or any further obligation under the Business Combination Agreement, except in the case of willful or material breach or actual fraud.

A copy of the Business Combination Agreement is filed with this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference, and the foregoing description of the Business Combination Agreement is qualified in its entirety by reference thereto. The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of the Business Combination Agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The representations, warranties and covenants in the Business Combination Agreement are also modified in important part by the underlying disclosure schedules which are not filed publicly and which are subject to a contractual standard of materiality different from that generally applicable to stockholders and were used for the purpose of allocating risk among the parties rather than establishing matters as facts. We do not believe that these schedules contain information that is material to an investment decision.

Sponsor Letter Agreement

Concurrent with the execution of the Business Combination Agreement, ARYA Sciences Holdings, a Cayman Islands exempted company (“ARYA Sponsor”), ARYA, TopCo and ARYA’s independent directors entered into a Sponsor Letter Agreement (the “Sponsor Letter Agreement”), pursuant to which (a) each of ARYA Sponsor and the ARYA independent directors agreed to vote in favor of the Business Combination Agreement and the transactions contemplated hereby, (b) ARYA Sponsor agreed to forfeit the warrants it purchased in a private placement in connection with the ARYA initial public offering and (c) the ARYA Sponsor and the ARYA independent directors have agreed to waive any adjustment to the conversion ratio set forth in the ARYA’s amended and restated memorandum and articles of association or any other anti-dilution or similar protection with respect to the Class B ordinary shares of ARYA held by them.

A copy of the Sponsor Letter Agreement is filed with this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference, and the foregoing description of the Sponsor Letter Agreement is qualified in its entirety by reference thereto.

Private Placement

Concurrently with the execution of the Business Combination Agreement, ARYA and TopCo entered into Subscription Agreements with certain investors (collectively, the “Private Placement Investors”) pursuant to which, among other things, such investors agreed to subscribe for and purchase and TopCo agreed to issue and sell to such investors, 10,415,000 TopCo Ordinary Shares (the “Private Placement Shares”), for an aggregate of $104,150,000 (the “Private Placement”) in proceeds. The closing of the Private Placement is contingent upon, among other things, the substantially concurrent consummation of the Business Combination and related transactions.

In connection with the Private Placement, TopCo will grant the Private Placement Investors certain customary registration rights. The Private Placement Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon the exemption provided in Section 4(a)(2) of the Securities Act and/or Regulation D or Regulation S promulgated thereunder without any form of general solicitation or general advertising.

The form of Subscription Agreement is attached as Exhibit 10.2 hereto.
