Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On April 28, 2020, resTORbio, Inc., a Delaware corporation (“resTORbio”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) among resTORbio, Adicet Bio, Inc., a Delaware corporation (“Adicet”), and Project Oasis Merger Sub, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of resTORbio (“Merger Sub”), pursuant to which, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Adicet will be merged with and into Merger Sub (the “Merger”) at the effective time of the Merger (the “Effective Time”), with Adicet continuing after the Merger as the surviving company and a wholly-owned subsidiary of resTORbio. The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.

At the Effective Time, each outstanding share of Adicet capital stock will be converted into the right to receive shares of resTORbio common stock, par value $0.0001 (the “resTORbio Common Stock”), as set forth in the Merger Agreement. Under the exchange ratio formula in the Merger Agreement, immediately following the Effective Time, the former Adicet securityholders are expected to own approximately 75% of the outstanding shares of resTORbio Common Stock on a fully-diluted basis and securityholders of resTORbio as of immediately prior to the Effective Time are expected to own approximately 25% of the outstanding shares of resTORbio Common Stock on a fully-diluted basis (in each case excluding equity incentives available for grant). In addition, as more fully described below, each holder of resTORbio Common Stock as of immediately prior to the Effective Time shall be entitled to one contractual contingent value right issued by resTORbio, subject to and in accordance with the terms and conditions of the CVR Agreement (as defined below), for each share of resTORbio Common Stock held by such holder. In connection with the Merger, resTORbio will assume certain outstanding Adicet options and warrants, subject to appropriate adjustment of the number and type of underlying shares and exercise price based on the exchange ratio formula in the Merger Agreement.

The Merger Agreement contains a customary “no-shop” provision under which neither resTORbio nor Adicet is permitted to (i) solicit any alternative acquisition proposals, (ii) furnish any non-public information to any person in connection with or in response to any alternative acquisition proposal, (iii) engage in any negotiations or discussions with any person with respect to any alternative acquisition proposal, (iv) approve, endorse or recommend any alternative acquisition proposal, (v) enter into any agreement relating to any alternative acquisition proposal, (vi) take any action that could reasonably be expected to lead to an alternative acquisition proposal, or (vii) publicly propose to do any of the foregoing. The “no-shop” provision is subject to certain exceptions that permit the board of directors of resTORbio, Inc. (the “resTORbio Board”), or the board of directors of Adicet, to comply with its respective fiduciary duties, which, under certain circumstances, would enable resTORbio or Adicet, as applicable, to provide information to, and enter into discussions or negotiations with, third parties in response to any alternative acquisition proposals.

The Merger Agreement contains customary representations, warranties and covenants made by Adicet and resTORbio, including covenants relating to obtaining the requisite approvals of the stockholders of Adicet and resTORbio, indemnification of directors and officers, and Adicet’s and resTORbio’s conduct of their respective businesses between the date of signing the Merger Agreement and the Effective Time.

The Merger Agreement provides each of resTORbio and Adicet with specified termination rights, and further provides that, upon termination of the Merger Agreement under specified circumstances, either party may be required to pay the other party a termination fee of $6,100,000. In addition, in connection with certain terminations of the Merger Agreement, either party may be required to pay the other party’s out-of-pocket fees and expenses up to $1,000,000.

The Merger Agreement provides that, immediately following the Effective Time, the board of directors of the combined company will consist of seven directors, comprised of five directors designated by Adicet, one director designated by resTORbio and the Chief Executive Officer of resTORbio (until each of their respective successors are duly elected or appointed and qualified or their earlier death, resignation or removal). In connection with the Merger, resTORbio will seek to amend its certificate of incorporation to: (i) effect a reverse split of resTORbio Common Stock at a ratio to be determined by resTORbio and Adicet and (ii) change the name of resTORbio to “Adicet Bio, Inc.”.

The resTORbio Board has approved the Merger Agreement and the related transactions, and has adopted resolutions recommending that the requisite stockholders of resTORbio approve the issuance of shares of resTORbio Common Stock pursuant to the Merger and approve the related amendments to resTORbio’s certificate of incorporation (the “resTORbio Stockholder Matters”). resTORbio has agreed to hold a stockholders’ meeting to submit the resTORbio Stockholder Matters to its stockholders for their consideration. In connection with the Merger, resTORbio intends to file a registration statement on Form S-4 with the Securities and Exchange Commission (“SEC”), which will include a proxy statement/prospectus with respect to the resTORbio Stockholder Matters (the “Form S-4”).

resTORbio’s and Adicet’s obligations to consummate the Merger are subject to the satisfaction or waiver of customary closing conditions, including, among others, obtaining the requisite approval of the resTORbio Stockholder Matters by the stockholders of resTORbio, the effectiveness of the Form S-4, and the requisite approval of the stockholders of Adicet (which such approval shall be obtained within five business days after the effectiveness of the Form S-4).

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about resTORbio or Adicet. The Merger Agreement contains representations, warranties and covenants that resTORbio and Adicet made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Merger Agreement between resTORbio and Adicet and may be subject to important qualifications and limitations agreed to by resTORbio and Adicet in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Merger Agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or security holders, or may have been used for the purpose of allocating risk between resTORbio and Adicet rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in resTORbio’s public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise.
