Item 1.01 Entry into a Material Definitive Agreement.

On August 17, 2018, Avista Healthcare Public Acquisition Corp., a Cayman Islands exempted company (“AHPAC”), Avista Healthcare Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of AHPAC (“Merger Sub”) and Organogenesis Inc., a Delaware corporation (“Organogenesis”) entered into an Agreement and Plan of Merger (the “Merger Agreement”).

Pursuant to the Merger Agreement, among other things, (i) AHPAC will transfer by way of continuation out of the Cayman Islands into the State of Delaware or domesticate as a Delaware corporation in accordance with Section 388 of the Delaware General Corporation Law, as amended and the Cayman Islands Companies Law (2018 Revision) (the “Domestication”); (ii) Merger Sub will merge with and into Organogenesis, the separate corporate existence of Merger Sub will cease and Organogenesis will be the surviving corporation and a direct wholly owned subsidiary of AHPAC (the “Merger”, and together with the Domestication and the other transactions contemplated by the Merger Agreement, the “Business Combination”).

The Merger Agreement

Consideration to Selling Equityholders in the Business Combination

Consideration payable to Holders of Organogenesis Common Stock

Subject to the terms and conditions of the Merger Agreement, each share of Organogenesis common stock, par value $0.001 (“Organogenesis Common Stock”) issued and outstanding immediately prior to the effective time of the Merger shall be automatically cancelled, extinguished and converted, into the right to receive 2.03 shares (the “Exchange Ratio”) of validly issued, fully paid in and nonassessable shares of Class A common stock, par value $0.0001 per share, of AHPAC (after giving effect to the Domestication) (“AHPAC Common Stock”).

Holders of Organogenesis Warrants

Subject to the terms and conditions of the Merger Agreement, each warrant to acquire shares of Organogenesis Common Stock (the “Organogenesis warrants”) outstanding and unexercised immediately prior to the Effective Time (other than Organogenesis warrants that expire or are deemed automatically net exercised immediately prior to the effective time according to their terms as of the date of the Merger Agreement as a result of the transactions contemplated by the Merger Agreement) will be cancelled and each holder thereof shall instead have the right to receive from AHPAC a new warrant for shares of AHPAC Common Stock (each, a “replacement warrant”). Each replacement warrant shall have, and be subject to, substantially the same terms and conditions set forth in the Organogenesis warrants, except that: (i) the number of shares of AHPAC Common Stock (after giving effect to the Domestication) which can be purchased with each replacement warrant shall equal a number of shares equal to (as rounded down to the nearest whole number) (A) the number of shares of Organogenesis Common Stock that the Organogenesis warrant entitled the holder thereof to acquire immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio; and (ii) the exercise price for each replacement warrant shall be equal to (as rounded up to the nearest whole cent) (A) the exercise price of the Organogenesis warrant (in U.S. Dollars), divided by (B) the Exchange Ratio.

Holders of Organogenesis Options

Subject to the terms and conditions of the Merger Agreement, each outstanding option to acquire shares of Organogenesis Common Stock (the “Organogenesis options”) (whether vested or unvested) shall be assumed by AHPAC and automatically converted into an option to purchase shares of AHPAC Common Stock (each, an “assumed option”). Each assumed option shall: (i) have the right to acquire a number of shares of AHPAC Common Stock equal to (as rounded down to the nearest whole number) the product of (A) the number of shares of Organogenesis Common Stock which the Organogenesis option had the right to acquire immediately prior to the Effective Time, multiplied by

(B) the Exchange Ratio; (ii) have an exercise price equal to (as rounded up to the nearest whole cent) the quotient of (A) the exercise price of the Organogenesis option (in U.S. Dollars), divided by (B) the Exchange Ratio; (iii) be subject to the same vesting schedule as the applicable Organogenesis option; and (iv) be administered by the Board of Directors of AHPAC (the “AHPAC Board”) or a committee thereof.

Listing of AHPAC Common Stock

The AHPAC Common Stock is expected to be listed on the NASDAQ Capital Market (“NASDAQ”) upon consummation of the Business Combination.

Covenants

The Merger Agreement contains additional covenants of the parties, including, among others, covenants providing for (a) the parties to conduct their respective businesses in the ordinary course through the closing, (b) AHPAC and Organogenesis to cease discussions for alternative transactions, (c) AHPAC to prepare and file a registration statement on Form S-4 as promptly as reasonably practicable to provide AHPAC’s shareholders with the opportunity to redeem their AHPAC Common Stock, to solicit proxies from the AHPAC shareholders to vote on, among other matters, the issuance of shares of AHPAC Common Stock and proposals regarding the Business Combination, and to solicit approval of the Merger via written consent from the stockholders of Organogenesis, (d) the protection of, and access to, confidential information of the parties, (e) the parties to use reasonable best efforts to obtain necessary approvals from governmental agencies and (f) the parties to take all reasonable steps to cause the repayment and satisfaction in full of certain outstanding debt obligations of Organogenesis pursuant to the Exchange Agreement (as described below).

Governance

After the consummation of the Business Combination, AHPAC will have a single-tier board that will consist of eight directors. Each of the directors will serve for a one year term and until his or her successor is elected or, if earlier, upon such director’s resignation, removal or death.

Conditions to Closing of the Business Combination

The consummation of the Business Combination is subject to customary closing conditions, including approval by AHPAC’s shareholders and the applicable waiting period under the HSR Act having expired or been terminated. In addition, consummation of the Business Combination is subject to (a) the availability of at least $5,000,001 of net tangible assets, (b) the listing of AHPAC Common Stock on NASDAQ upon the closing, (c) the consummation of the transactions contemplated by the Exchange Agreement (as described below), (d) the consummation of the private placement (as described below) and (e) no material adverse effect with respect to Organogenesis shall have occurred.

Representations and Warranties

The parties to the Merger Agreement have made representations and warranties that are customary for transactions of this nature. The representations and warranties of the parties contained in the Merger Agreement or in any instrument delivered pursuant to the Merger Agreement will terminate and be of no further force and effect as of the closing.

Termination

The Merger Agreement may be terminated at any time prior to the closing, whether before or after the required AHPAC shareholder approval has been obtained by mutual written consent of AHPAC and Organogenesis, and in certain other circumstances, including if the Business Combination has not been consummated by October 14, 2018, or, if the shareholders of AHPAC approve the extension of the date by which AHPAC must consummate a Business Combination,

February 15, 2019, and the delay in closing beyond such date is not due to the breach of the Merger Agreement by the party requesting termination.

The foregoing description of the Merger Agreement and the Business Combination do not purport to be complete and is qualified in its entirety by the terms and conditions of the Merger Agreement and any related agreements. The Merger Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such 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 Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about AHPAC or any other party to the Merger Agreement. In particular, the representations, warranties, covenants and agreements contained in the Merger Agreement, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and security holders. Investors and security holders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Merger Agreement. 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 AHPAC’s public disclosures.

A copy of the Merger 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 Merger Agreement is qualified in its entirety by reference thereto.

These factors include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement and the proposed Business Combination contemplated therein; (2) the inability to complete the transactions contemplated by the Merger Agreement due to the failure to obtain approval of the stockholders of AHPAC or other conditions to closing in the Merger Agreement; (3) the ability to meet applicable NASDAQ listing standards; (4) the risk that the proposed Business Combination disrupts current plans and operations of Organogenesis as a result of the announcement and consummation of the transactions described herein; (5) the ability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (6) costs related to the proposed Business Combination; (7) changes in applicable laws or regulations; (8) the possibility that Organogenesis may be adversely affected by other economic, business, and/or competitive factors; and (9) other risks and uncertainties indicated from time to time in the definitive registration statement of AHPAC filed in connection with the proposed Business Combination and the joint proxy/consent solicitation statement/prospectus contained therein, including those under “Risk Factors” therein, and other documents filed or to be filed with the Securities and Exchange Commission by AHPAC. Investors are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made.
