ENVIU Environmental Impact Acquisition Corporation

Agreement and Plan of Merger

On May 29, 2023 Greenlight Biosciences Holdings, PBC, a Delaware Corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), with SW ParentCo, Inc., a Delaware corporation (“Parent”), and SW MergerCo, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Parent (the “Surviving Corporation”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Parent has agreed to cause Merger Sub to commence a tender offer (as it may be extended, amended or supplemented from time to time, the “Offer”), to acquire all of the outstanding shares of common stock, par value $0.0001 per share, of the Company (the “Company Common Stock”), other than certain excluded shares, for $0.30 per share, net to the seller in cash, without interest thereon (the “Offer Price”), and subject to any required withholding, upon the terms and subject to the conditions of the Merger Agreement.

The Offer will initially remain open for 20 business days (as calculated in accordance with Rule 14d-1(g)(3) under the Securities Exchange Act of 1934, as amended) from (and including) the date of commencement of the Offer. If at the scheduled expiration time of the Offer, any condition to the Offer (other than any conditions that by their nature are to be satisfied at the expiration of the Offer, but subject to such conditions remaining capable of being satisfied) has not been satisfied and has not been waived by Parent or Merger Sub (to the extent waivable), Merger Sub may, in its discretion, and Parent may cause Merger Sub to, extend the Offer in accordance with the terms of the Merger Agreement to permit the satisfaction of all Offer conditions. The obligation of Merger Sub to consummate the Offer is subject to the satisfaction or waiver of conditions, including, among others, there being a number of shares of Company Common Stock validly tendered (and not properly withdrawn) prior to the expiration of the Offer (but excluding shares tendered pursuant to guaranteed delivery procedures that have not yet been “received” by the “depository,” as such terms are defined in section 251(h)(6) of the Delaware General Corporate Law (the “DGCL”)), together with any shares of Company Common Stock otherwise owned by Merger Sub or its “affiliates” (as defined in section 251(h)(6) of the DGCL) that do not represent at least (a) a majority of the outstanding Company Common Stock, not otherwise owned by Merger Sub, its “affiliates” (as defined in section 251(h)(6) of the DGCL) or the Rollover Stockholders, (as defined below) and (b) the number of the shares of Company Common Stock outstanding immediately following the consummation of the Offer that, together with the shares of Company Common Stock owned by Merger Sub, its “affiliates” (as defined in section 251(h)(6) of the DGCL) and the Rollover Stockholders, equals at least such percentage of the shares of Company Common Stock, and of each class or series thereof, that would be required to adopt the Merger Agreement under the DGCL and the Company’s organizational documents (the “Minimum Condition”).

The Merger is to become effective, upon the terms and subject to the conditions of the Merger Agreement, at the date and time when a certificate of merger (the “Certificate of Merger”) has been duly filed with the Secretary of State of the State of Delaware, or at such later date and time as is agreed upon in writing by the parties and specified in the Certificate of Merger (the “Effective Time”). At the Effective Time, each share of Company Common Stock shall be converted automatically into and shall thereafter represent only the right to receive the Offer Price (other than shares of Company Common Stock (i) owned by the Company as treasury stock (ii) owned by Merger Sub immediately before the Effective Time, (iii) that were irrevocably accepted by Merger Sub in the Offer, (iv) held by stockholders who have perfected their statutory rights of appraisal under Section 262 of the DGCL or (v) that are subject to the Contribution and Exchange Agreements (as defined below)), subject to applicable withholding.

At the Effective Time, each share of capital stock of Merger Sub issued and outstanding immediately before the Effective Time shall be converted into and become one fully paid and non-assessable share of common stock, par value $0.0001 per share, of the Surviving Corporation. The Merger Agreement was unanimously approved by a special committee (the “Special Committee”) appointed by the board of directors of the Company (the “Board”) and recommended to the full Board, which resolved to recommend the Company’s stockholders tender their shares of Company Common Stock in the Offer (the “Company Recommendation”).

The Merger Agreement contains customary representations, warranties and covenants of the Company, Parent and Merger Sub, including, among others, covenants by the Company to conduct its business in the ordinary course of business during the period between execution of the Merger Agreement and the consummation of the Merger (the “Closing”) and prohibiting the Company from engaging in certain kinds of activities during such period without the consent of Parent. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract between the respective parties and are subject to 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 a confidential disclosure schedule made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts) and are subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors, security holders or securities laws. Investors and security holders are not and will not be 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 the Company’s public disclosures. The Merger Agreement also contains customary termination provisions for both the Company and Parent, as described in more detail below.

The Merger is subject to customary closing conditions. The Closing shall occur without a vote of the stockholders of the Company in accordance with Section 251(h) of the DGCL.

The Merger Agreement provides for a 30-day “go-shop” period beginning on the date of the Merger Agreement and continuing until 11:59 p.m. (New York City time) on June 28, 2023, during which period the Company and its representatives are permitted to actively initiate, solicit, knowingly facilitate or encourage alternative acquisition proposals from third parties and to provide information to, and participate in discussions and engage in negotiations with, third parties regarding any alternative acquisition proposals. After such 30-day go-shop period and subject to certain exceptions, the Company will be subject to a customary “no-shop” provision whereby it is prohibited from (i) entering into solicitations, discussions or negotiations concerning, or providing confidential information in connection with, any alternative transaction and (ii) withholding, withdrawing, qualifying, amending or modifying the Company Recommendation in a manner adverse to Parent.

The “no shop” provision allows the Company, under certain circumstances and in compliance with certain obligations set forth in the Merger Agreement, to provide non-public information and engage in discussions and negotiations with respect to an unsolicited acquisition proposal that constitutes or is reasonably expected to lead to an alternative transaction that the Board (or an authorized committee thereof, including the Special Committee) determines would be more favorable, from a financial point of view, to the Company’s stockholders than the Merger and in the best interests of those materially affected by the Company’s conduct (a “Superior Proposal”).

Under certain circumstances and in compliance with certain obligations set forth in the Merger Agreement, the Company is permitted to terminate the Merger Agreement prior to the Acceptance Time (as defined in the Merger Agreement) to accept a Superior Proposal, subject to the payment of an expense reimbursement. The Company is also required to pay an expense reimbursement (A) if Parent terminates because, (i) the Board, acting on the recommendation of the Special Committee, shall have effected an Adverse Recommendation Change (as defined in the Merger Agreement); provided, that Parent must provide notice of termination within five (5) business days of the Adverse Recommendation Change, (ii) the Company materially breaches Section 5.3 of the Merger Agreement, (iii) the Company fails to recommend against a competing tender or exchange offer within ten (10) business days thereof, (iv) the Company fails to publicly affirm the Company Recommendation in favor of the Offer within ten (10) business days of a request from Parent (when permitted to make such a request under the Merger Agreement), or (v) the Acceptance Time has not occurred by February 29, 2024 (or as extended in accordance with the Merger Agreement) if as of such time Parent could have terminated the Merger Agreement pursuant to any of clauses (i) through (iv) immediately above or (B) if, following the date of the Merger Agreement, (i) an alternative acquisition proposal is publicly announced and has not been withdrawn prior to termination of the Merger Agreement, (ii) (x) Parent terminates the Merger Agreement because the Company breaches any of its representations or warranties, or fails to perform any of its covenants or agreements contained in the Merger Agreement, in any such case, which gives rise to the failure of certain offer conditions in the Merger Agreement (and such breach is not cured within 20 business days thereof or is not capable of being cured), or (y) either party terminates the Merger Agreement because the Offer has expired as a result of the non-satisfaction of one or more offer conditions or has been terminated or withdrawn and (iii) within 12 months after termination, the Company consummates any alternative transaction or enters into a definitive agreement providing for an alternative transaction. In no event would the Company be required to pay an expense reimbursement fee on more than one occasion. The Company’s expense reimbursement obligation cannot exceed $1,575,000.

If the Acceptance Time occurs, the Company must reimburse Parent for all of its fees and expenses relating to the Merger Agreement, the Note Purchase Agreement, the Contribution and Exchange Agreements and the transactions contemplated thereby, including the Offer and the Merger, without any cap.

Immediately prior to the Effective Time:

Payment of the Company Option Cash Out Amount and the Company RSU Cash Out Amount shall be made no later than thirty (30) business days following the Closing, subject to any applicable withholding taxes.

In addition, the Company shall promptly take all necessary actions to ensure that no offering or purchase period commences under the Company’s 2022 Employee Stock Purchase Plan (the “Company ESPP”) and that no shares of capital stock of the Company are issued under the Company ESPP. Prior to the Effective Time, the Company shall take all necessary actions to terminate the Company ESPP.

At the Effective Time, each outstanding warrant to purchase shares of Company Common Stock pursuant to the Warrant Agreement, dated January 13, 2021, by and between Environmental Impact Acquisition Corp. and Continental Stock Transfer & Trust Company (the “Warrant Agreement”) will, in accordance with its terms, automatically and without any required action on the part of the holder thereof, become a warrant exercisable for the Offer Price that such holder would have received if such warrant had been exercised immediately prior to the Effective Time; provided that if a holder of such warrant properly exercises such warrant within thirty (30) days following the public disclosure of the consummation of the Merger, the holder of such warrant will be entitled to the Black-Scholes Warrant Value (as defined in the Warrant Agreement) with respect to such warrant, which would have been equal to approximately $0.00063989 per warrant as of the close of trading on May 26, 2023.

The foregoing description of the terms of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the terms and conditions of the Merger Agreement, a copy of which is filed as Exhibit 2.1 and is incorporated herein by reference.

Contribution and Exchange

In connection with the transactions contemplated by the Merger Agreement, Parent and certain existing stockholders of the Company (the “Rollover Stockholders”) each entered into a Contribution and Exchange Agreement (collectively, the “Contribution and Exchange Agreements”) pursuant to which the Rollover Stockholders agreed to contribute in aggregate 120,521,038 shares of Company Common Stock (the “Rollover Shares”) to Parent, in exchange for shares of Series A-2 Preferred Stock, par value $0.001 per share, of Parent. Such Rollover Shares constitute approximately 79.46% of the total issued and outstanding shares of Company Common Stock as of the date hereof. The Contribution and Exchange Agreements will terminate upon the first to occur of the consummation of the Merger, the date and time that the Merger Agreement is terminated in accordance with its terms and the date and time that the Board or the Special Committee make an Adverse Recommendation Change in accordance with the Merger Agreement.

Financing

In connection with the transactions contemplated by the Merger Agreement, Parent and certain investors entered into a Secured Convertible Note Purchase Agreement (the “Note Purchase Agreement”), to which the Company is a third party beneficiary, under which Parent shall issue up to $100 million of Convertible Secured Promissory Notes (“Parent Notes”) to the investors at the Closing, of which $52.075 million is committed as of the date hereof with the $52.075 million being inclusive of $15 million in Advance Notes (as defined below).

In connection therewith, the Company will receive $15 million of cash and will issue $15 million of unsecured notes (the “Advance Notes”) for the purpose of providing working capital to the Company. At Closing, the Advance Notes shall automatically be exchanged for Parent Notes issued by Parent, with the principal balance of the Advance Notes plus all accrued interest being credited towards the Parent Notes principal amount on a dollar-for-dollar basis.

The Advance Notes will bear interest at a fixed rate equal to 10% per annum per year. In the event of payment defaults on interest or principal when due, the interest rate will be increased to 15% per annum. The Advance Notes will mature upon the earlier to occur of a written demand from the holders of a majority of the aggregate principal and May 30, 2024. The Advance Notes are subject to certain customary events of default, including upon certain bankruptcy or insolvency events after which the Advance Notes would become automatically due and payable. The Advance Notes are subordinated to the Company’s obligations under the (i) loan and security agreement with Horizon Technology Finance Corporation and Powerscourt Investments XXV, LP and (ii) loan and security agreement with Silicon Valley Bank.

The foregoing description of the terms of the Advance Notes does not purport to be complete and is qualified in its entirety by the terms and conditions of the Advance Notes, the form of which is filed as Exhibit 4.1 and is incorporated herein by reference.
