Merger Agreement

On August 14, 2023, the Reporting Persons entered into an Agreement and Plan of Merger (the “Merger Agreement”) with the Issuer.  Pursuant to the Merger Agreement, and upon the terms and subject to the conditions therein, Merger Sub will commence a tender offer (the “Offer”) to acquire all of the issued and outstanding shares of common stock, par value $0.001 per share, of Issuer (“Issuer Common Stock”), for (i) $1.1059 per share of Issuer Common Stock (the “Common Cash Amount”), in cash, subject to any applicable withholding of taxes and without interest, plus (ii) one contingent value right (each, a “CVR”) per share of Issuer Common Stock (the “Common CVR Amount”), which represents the right to receive up to approximately $2.5444 per share of Issuer Common Stock in the form of one or more potential contingent payments, in cash, subject to any applicable withholding of taxes and without interest, upon the achievement of certain milestones as set forth in, and subject to and in accordance with the terms and conditions of, the CVR Agreement (as defined below) (the Common Cash Amount plus the Common CVR Amount, collectively, or any different amount per share paid pursuant to the Offer to the extent permitted by the Merger Agreement, being the “Offer Price”).  The Offer will initially expire at 5:00 p.m. (New York City time) on the date that is 21 business days following the commencement of the Offer, subject to extension under certain circumstances.
 
Merger Sub’s obligation to accept for payment shares of Issuer Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer is subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, including that (i) the number of shares of Issuer Common Stock that have been validly tendered in accordance with the terms of the Offer and not validly withdrawn prior to the expiration of the Offer, when considered together with all other shares of Issuer Common Stock (if any) beneficially owned by the Reporting Persons and its controlled affiliates, represent at least one share more than 50% of the total number of outstanding shares of Issuer Common Stock at the time of the expiration of the Offer (excluding any shares of Issuer Common Stock tendered pursuant to guaranteed delivery procedures that have not yet been “received” (as such term is defined in Section 251(h)(6)(f) of the DGCL)), (ii) there is no governmental entity of competent and applicable jurisdiction having enacted, issued, promulgated, enforced or entered any order or law that is in effect and restrains, enjoins or otherwise prohibits or makes illegal consummation of the Offer or the Merger, (iii) the representations and warranties of Issuer contained in the Merger Agreement are accurate, subject to customary thresholds and exceptions, (iv) Issuer has performed or complied with in all material respects its obligations or covenants required to be performed or complied with under the Merger Agreement, (v) there has not been nor will there be a continuing Company Material Adverse Effect (as defined in the Merger Agreement) and (vi) other customary conditions set forth in Annex I of the Merger Agreement have been satisfied.

Following the consummation of the Offer, upon the terms and conditions set forth in the Merger Agreement and in accordance with the DGCL, Merger Sub will merge with and into Issuer (the “Merger”), with Issuer continuing as the surviving corporation (the “Surviving Corporation”) in the Merger.  The Merger will be governed by and effected under Section 251(h) of the DGCL, with no stockholder vote required to consummate the Merger.

Pursuant to the Merger, each issued and outstanding share of Issuer Common Stock (other than shares of Issuer Common Stock (a) held in the treasury of Issuer, (b) that as of the commencement of the Offer were owned by the Reporting Persons, (c) irrevocably accepted for payment in the Offer, or (d) held by holders who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, Section 262 of the General Corporation Law of the State of Delaware, and, as of the effective time of the merger, has neither effectively withdrawn nor lost his, or, or its rights to such appraisal and payment (collectively, the “Excluded Shares”)) will be automatically cancelled and converted into the right to receive an amount in cash and CVR equal to the Offer Price.


In addition, immediately prior to the effective time of the Merger (the “Effective Time”), by virtue of, and as a condition to, the Merger and without any action on the part of any holder thereof:
 

Each option to purchase Issuer Common Stock (“Company Option”), whether vested or unvested, that has a per share exercise price that is less than the Common Cash Amount that is outstanding and unexercised immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive for each share of Issuer Common Stock underlying such Company Option, without interest and subject to deduction for any required withholding under applicable tax law, (A) an amount in cash from the Reporting Persons or the Surviving Corporation equal to the excess of the Common Cash Amount over the per share exercise price of such Company Option and (B) one CVR;
 

Each Company Option that has a per share exercise price that is equal to or greater than the Common Cash Amount but less than $2.71, whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive for each share of Issuer Common Stock underlying such qualifying Company Option, without interest and subject to deduction for any required withholding under applicable tax law, upon the occurrence of any Milestone Payment (as defined in the CVR Agreement) a cash payment, if any, equal to (A) the amount, if any, by which (i) the Common Cash Amount plus the applicable Milestone Payment plus any Milestone Payment that was previously paid that exceeds (ii) the per share exercise price of such Company Option, minus (B) the gross amount of Milestone Payments previously paid with respect to such share of Issuer Common Stock underlying such Company Option;
 

Each Company Option that has a per share exercise price equal to or greater than $2.71 will be cancelled at the Effective Time without any consideration payable therefor (whether in the form of cash or a CVR or otherwise); and
 

Each restricted stock award of Issuer subject to vesting conditions based solely on continued employment or service to Issuer and its subsidiary (“Company Restricted Stock Award”) that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be cancelled and automatically converted into the right to receive for each share of Issuer Common Stock subject to such Company Restricted Stock Award, without interest and subject to deduction for any required withholding under applicable tax law, (i) an amount in cash from the Reporting Persons or the Surviving Corporation equal to the Common Cash Amount and (ii) one CVR.
 
The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is listed as Exhibit 99.1 hereto and incorporated by reference to Exhibit 2.1 to Harmony’s Current Report on Form 8-K filed with the SEC on August 14, 2023.

Tender and Support Agreements

On August 14, 2023, in connection with the execution of the Merger Agreement, the directors and executive officers of Issuer, other than Kenneth Jones (the “Supporting Stockholders”), entered into Tender and Support Agreements with the Reporting Persons (the “Support Agreements”).  Under the terms of the Support Agreements, each Supporting Stockholder has agreed, among other things, to tender, pursuant to the Offer, his or her shares of Issuer Common Stock in the Offer (“Supporting Stockholder Shares”), vote his or her Supporting Stockholder Shares, if applicable, and, subject to certain exceptions, not to transfer any of his or her Supporting Stockholder Shares. The Support Agreements will terminate upon termination of the Merger Agreement and certain other specified events.
 
The foregoing description of the Support Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the form of Support Agreement, which is listed as Exhibit 99.2 hereto and incorporated by reference to Exhibit 99.1 to Harmony’s Current Report on Form 8-K filed with the SEC on August 14, 2023.
 
The purpose of the Offer is for Harmony to acquire control of the Issuer. The Offer would be the first step in Harmony’s acquisition of the entire equity interest in the Issuer. The Offer is intended to facilitate the acquisition of all issued and outstanding Shares. The purpose of the Merger is to acquire all issued and outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is consummated, Purchaser intends to complete the Merger as soon as practicable thereafter.


Following the Merger, the Issuer will become a wholly owned subsidiary of Harmony. In addition, Harmony will cause the Shares to be delisted from the Nasdaq Capital Market and deregistered under the Exchange Act.

The Offer referenced in this document has not yet commenced.  This document is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell shares of the Issuer, nor is it a substitute for the tender offer materials that the Reporting Persons will file with the SEC upon commencement of the tender offer. At the time the tender offer is commenced, the Reporting Persons will file tender offer materials on Schedule TO, and the Issuer will file a Solicitation/Recommendation Statement on Schedule 14D-9 with the SEC with respect to the tender offer. HOLDERS OF SHARES OF ISSUER COMMON STOCK ARE URGED TO READ THE TENDER OFFER MATERIALS (INCLUDING AN OFFER TO PURCHASE, A RELATED LETTER OF TRANSMITTAL AND CERTAIN OTHER TENDER OFFER DOCUMENTS) AND THE SOLICITATION/RECOMMENDATION STATEMENT WHEN THEY BECOME AVAILABLE (AS EACH MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME) BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION THAT HOLDERS OF SHARES OF ISSUER COMMON STOCK SHOULD CONSIDER BEFORE MAKING ANY DECISION REGARDING TENDERING THEIR SHARES. The Offer to Purchase, the related Letter of Transmittal and certain other tender offer documents, as well as the Solicitation/Recommendation Statement, will be made available to all holders of shares of Issuer at no expense to them. The tender offer materials and the Solicitation/Recommendation Statement will be made available for free at the SEC’s website at www.sec.gov. In addition, these materials will be available at no charge on the Enhanced SEC Filings section of the Investor Relations page of Issuer’s website at www.zynerba.com and by directing a request to the information agent for the tender offer, whose contact information will be set forth in the Offer to Purchase.
