W I T N E S S E T H

WHEREAS, the respective Boards of Directors of Ensysce, Signature and Merger Sub have each (i) determined that the Merger (as defined in Section 1.1(a) hereof) is advisable and fair to, and in the best interests of, their respective stockholders and (ii) approved this Agreement and the Merger upon the terms and subject to the conditions set forth herein, and in accordance with the Delaware General Corporation Law (the “DGCL”), whereby each issued and outstanding share of common stock, par value $0.0001 per share (the “Common Stock”), of Ensysce (other than shares of Common Stock owned, directly or indirectly, by Signature or by Ensysce immediately prior to the Effective Time (as defined in Section 1.1(b) hereof) and Dissenting Shares (as defined in Section 1.2(d) hereof)), will, upon the terms and subject to the conditions and limitations set forth herein, be converted into the right to receive shares of Common Stock, par value $0.000025 per share, of Signature (the “Signature Shares”); and

WHEREAS, for federal income tax purposes, the Merger is intended to qualify as a reorganization under the provisions of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”).

NOW, THEREFORE, in consideration of the representations, warranties, covenants, agreements and conditions set forth herein, and intending to be legally bound hereby, the parties hereto agree as follows:

Article 1
THE MERGER

Section 1.1 The Merger. 

(a) Upon the terms and subject to the conditions of this Agreement, and in accordance with the DGCL, at the Effective Time, Merger Sub shall be merged (the “Merger”) with and into Ensysce, whereupon the separate existence of Merger Sub shall cease, and Ensysce shall continue as the surviving corporation (sometimes referred to herein as the “Surviving Corporation”) and shall continue to be governed by the laws of the State of Delaware and shall continue under the name “Ensysce Biosciences, Inc.”

(b) Concurrently with the Closing (as defined in Section 1.7 hereof), Merger Sub and Ensysce shall cause a certificate of merger substantially in the form attached hereto as Exhibit A (the “Certificate of Merger”) with respect to the Merger to be executed and filed with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”) as provided in the DGCL. The Merger shall become effective on the date and time at which the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware in accordance with Section 251 of the DGCL or at such other date and time as is agreed between the parties and specified in the Certificate of Merger, and such date and time is hereinafter referred to as the “Effective Time.”

(c) The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing and subject thereto, from and after the Effective Time, the Surviving

Corporation shall possess all properties, rights, privileges, immunities, powers and franchises and be subject to all of the obligations, restrictions, disabilities, liabilities, debts and duties of Merger Sub and Ensysce.

Section 1.2 Effect on the Common Stock and Merger Sub Securities. At the Effective Time: 

(a) Cancellation of Shares of Common Stock. Each share of Common Stock held by Ensysce as treasury stock and each share of Common Stock owned by Signature or Merger Sub immediately prior to the Effective Time shall automatically be cancelled and retired and cease to exist, and no consideration or payment shall be delivered therefor or in respect thereto. All shares of Common Stock to be converted into Merger Consideration pursuant to this Section 1.2 shall, by virtue of the Merger and without any action on the part of the holders thereof, cease to be outstanding, be cancelled and retired and cease to exist, and each holder of a certificate (representing prior to the Effective Time any such shares of Common Stock) shall thereafter cease to have any rights with respect to such shares of Common Stock, except the right to receive the Signature Shares into which such shares of Common Stock have been converted.

(b) Conversion of Shares of Common Stock. Subject to Section 1.2(c), Signature shall issue to the stockholders of Ensysce an aggregate number of Signature Shares (the “Merger Consideration”) equal to (x) the Signature Total Fully Diluted Shares, minus (y) the sum of (i) the number of Signature Shares otherwise issuable to the holders of Dissenting Shares, plus (ii) the Adjusted Assumed Ensysce Options (as defined in Section 1.4 below), and each share of Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Common Stock referred to in the first sentence of Section 1.2(a) hereof and Dissenting Shares) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive a portion of the Merger Consideration equal to the Common Exchange Ratio. For purposes hereof, (i) the “Common Exchange Ratio” shall mean, with respect to each holder of Ensysce Common Stock, other than holders of Dissenting Shares, the number computed, immediately prior to the Effective Time, by dividing (x) the number of shares of Common Stock held by that Ensysce shareholder, by (y) total shares of Common Stock outstanding immediately prior to the Effective Time, excluding Dissenting Shares and shares of Common Stock cancelled pursuant to Section 1.2(a), and (ii) the “Signature Total Fully Diluted Shares” shall mean, as of immediately prior to the Effective Time, the sum of (x) the number of Signature Shares outstanding and (y) the number of Signature Shares issuable upon exercise of all outstanding Retained Signature Stock Options (as defined in Section 5.16 below), but excluding for purposes of this calculation (A) any shares of capital stock held in the treasury of Signature and (B) any Signature Shares issuable pursuant to Section 5.17 hereof.

(c) Conversion of Merger Sub Capital Stock. The shares of capital stock of Merger Sub immediately prior to the Effective Time shall be converted into and become outstanding shares of capital stock of the Surviving Corporation.

(d) Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary, if and to the extent required by the DGCL, shares of Common Stock which are issued and outstanding immediately prior to the Effective Time and which are held by holders of such shares of Common Stock who have properly exercised appraisal rights with respect thereto (the “Dissenting Shares”) in accordance with Section 262 of the DGCL, shall not be exchangeable for the right to receive any portion of the Merger Consideration, and holders of such Dissenting Shares shall be entitled to receive payment of the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL unless and until such holders fail to perfect or effectively withdraw or otherwise lose their rights to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such Dissenting Shares shall thereupon be treated as if they had been converted into and to have become exchangeable for, at the Effective Time, the right to receive a proportionate share of the Merger Consideration payable in respect of Common Stock for which no election to receive cash or stock has been made, without any interest thereon. Notwithstanding anything to the contrary contained in this Section 1.2(d), if this Agreement is terminated prior to the Effective Time, then the right of any stockholder to be paid the fair value of such stockholder’s Dissenting Shares pursuant to Section 262 of the DGCL shall cease. Ensysce shall give Signature (i) prompt notice of any written demands received by Ensysce for appraisal of Dissenting Shares, withdrawals of such demands and any other instruments served pursuant to the DGCL which are received by Ensysce relating to such holder’s rights of appraisal, and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Ensysce shall not, except with the prior written consent of Signature, make any payment with respect to any demand for appraisal or offer to settle or settle any such demands.

Section 1.3 Exchange of Certificates. 

(a) As of or promptly following the Effective Time, Signature shall mail (and make available for collection by hand) to each holder of record of a certificate or certificates, which immediately prior to the Effective Time represented outstanding shares of Common Stock (other than Dissenting Shares) (the “Certificates”), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to Signature and which shall be in the form and have such other provisions as Ensysce and Signature may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the portion of the Merger Consideration into which the number of shares of Common Stock previously represented by such Certificate shall have been converted pursuant to this Agreement (which instructions shall provide that at the election of the surrendering holder, Certificates may be surrendered, and the Merger Consideration in exchange therefor collected, by hand delivery). Upon surrender of a Certificate for cancellation to Signature, together with a letter of transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor a ratable share of the Merger Consideration for each share of Common Stock formerly represented by such Certificate, to be mailed (or made available for collection by hand if so elected by the surrendering holder) within three business days of receipt thereof (but in no case prior to the Effective Time), and the Certificate so surrendered shall be forthwith cancelled. Signature shall accept such Certificates upon compliance with such reasonable terms and conditions as Signature may impose to effect an orderly exchange thereof in accordance with normal exchange practices.

(b) No fraction of a Signature Share will be issued by virtue of the Merger, but in lieu thereof each holder of shares of Common Stock who would otherwise be entitled to a fraction of a Signature Share (after aggregating all fractional Signature Shares that otherwise would be received by such holder) shall, upon surrender of such holder’s Certificate(s), receive a number of Signature Shares that shall be rounded up or down in accordance with ordinary rounding conventions.

Section 1.4 Stock Options. Each then outstanding stock option of Ensysce (the “Assumed Ensysce Options”) listed on Schedule 1.4 attached hereto, whether vested or unvested, will be assumed by Signature and represent an option to acquire, upon exercise, a number of Signature Shares (the “Adjusted Option Shares”) equal to the number of Signature Shares that would have been issuable on Closing of the Merger had the Assumed Ensysce Options been exercised immediately prior to the Effective Date (the total number of Signature Shares issuable upon exercise of all Assumed Ensysce Options, as so adjusted, being referred to as the “Adjusted Assumed Ensysce Options”), at an exercise price per Signature Share equal to the quotient obtained by dividing (x) the aggregate exercise price of such Assumed Ensysce Option, by (y) the Adjusted Options Shares with respect to such Assumed Ensysce Option. Except for the above adjustment to the number of shares issuable on exercise of the Assumed Ensysce Options and the corresponding adjustment to the exercise price of the same, the vesting provisions and all other provisions of the Assumed Ensysce Options shall be unchanged as a result of the Merger. Any stock options of Ensysce, other than the Assumed Ensysce Options listed on Schedule 1.4, shall, to the extent not previously exercised, be cancelled on or prior to the Effective Date. 

Section 1.5 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Signature, the receipt of such other evidence as Signature shall deem reasonably appropriate, Signature will issue in exchange for such lost, stolen or destroyed Certificate the Signature Shares to which the holder thereof is entitled pursuant to this Article I. 

Section 1.6 Merger Closing. Subject to the satisfaction or waiver of the conditions set forth in Article VI hereof, the closing of the Merger (the “Closing”) will take place at 10:00 a.m. Central time on such on a date and at a place to be specified by the parties hereto, and no later than the second business day after the satisfaction or waiver of the conditions set forth in Article VI hereof that are to be satisfied 1 other than on the day of Closing, unless another time, date or place is agreed to in writing by the parties hereto (such date, the “Closing Date”).

Section 1.7 Possible Alternative Structure. In the event that Ensysce or Signature reasonably determines prior to the Effective Time that (i) there is a material possibility that the transactions contemplated by this Agreement will not constitute a “reorganization” within the meaning of Section 368(a) of the Code, (ii) there is a material possibility that the Merger will result in a material corporate level tax, or (iii) there are material tax benefits available if the transactions contemplated by this Agreement are restructured, such party may request that the structure of the acquisition of Ensysce contemplated by this Agreement be altered in a manner so as to permit (i) the transactions contemplated by this Agreement to qualify as a reorganization under Section 368 of the Code or a transfer under Section 351 of the Code, (ii) the avoidance of such material corporate-level tax, or (iii) the achievement of such tax benefits as applicable. In any case, corresponding changes to this Agreement shall be made consistent with such structure but without any material adverse change in the economic consequences to Ensysce, Signature or their respective stockholders. 

Article 2
THE SURVIVING CORPORATION

Section 2.1 Certificate of Incorporation. The Certificate of Incorporation of Ensysce in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by law and such Certificate of Incorporation of the Surviving Corporation. 

Section 2.2 By-Laws. The by-laws of Ensysce in effect at the Effective Time shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law, the certificate of incorporation of such entity and the by-laws of such entity. 

Section 2.3 Officers and Directors. The respective officers and directors of Ensysce immediately prior to the Effective Time shall be the officers and directors of the Surviving Corporation.

Signature represents and warrants to Ensysce, subject to such exceptions as are specifically disclosed in writing in the disclosure letter supplied by Signature to Ensysce, which disclosure shall provide an exception to or otherwise qualify the representations or warranties of Signature specifically referred to in such disclosure and such other representations and warranties to the extent such disclosure shall reasonably appear to be applicable to such other representations or warranties (the “Signature Disclosure Schedule”) as follows:

Section 3.1 Corporate Existence and Power. Each of Signature and Merger Sub is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware, and has all corporate powers and all governmental licenses, authorizations, consents and approvals (collectively, “Licenses”) required to carry on its business as now conducted or presently proposed to be conducted except for failures to have any such License which would not, in the aggregate, have a Signature Material Adverse Effect (as defined below). Each of Signature and Merger Sub is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned, leased or operated by it or the nature of its activities makes such qualification necessary, except in such jurisdictions where failures to be so qualified would not reasonably be expected to, in the aggregate, have a Signature Material Adverse Effect. As used herein, the term “Signature Material Adverse Effect” means a material adverse effect on the financial condition, business, assets or results of operations of Signature or Merger Sub, taken as a whole. Signature has heretofore delivered or made available to Ensysce true and complete copies of the Certificate of Incorporation and the by-laws of Signature and Merger Sub as currently in effect.

(a) Signature and Merger Sub each have the requisite corporate power and authority to execute and deliver this Agreement and, subject to approval of Signature’s stockholders, as set forth in Section 3.2(b) hereof and as contemplated by Section 5.3 hereof, to perform its obligations hereunder. The execution and delivery of this Agreement and the performance of its obligations hereunder have been duly and validly authorized by the Board of Directors of Signature and Merger Sub, and no other corporate proceedings on the part of Signature or Merger Sub, other than the approval of Signature’s stockholders, are necessary to authorize the execution, delivery and performance of this Agreement. This Agreement has been duly executed and delivered by Signature and Merger Sub and constitutes, assuming due authorization, execution and delivery of this Agreement by Ensysce, a valid and binding obligation of Signature and Merger Sub, enforceable against Signature and Merger Sub in accordance with its terms.

(b) No filing or registration with, notification to, or authorization, consent or approval of, any government or any agency, court, tribunal, commission, board, bureau, department, political subdivision or other instrumentality of any government (including any regulatory or administrative agency), whether federal, state, multinational, provincial, municipal, domestic or foreign (each, a “Governmental Entity”) is required in connection with the execution and delivery of this Agreement by Signature or Merger Sub or the performance by Signature or Merger Sub, as applicable, of its obligations hereunder, except (i) the filing of the Certificate of Merger in accordance with the DGCL; (ii) the filing of a Certificate of Amendment to the Certificate of Incorporation of Signature, as required by Section 5.3 of this Agreement, in accordance with the DGCL; (iii) compliance with any applicable requirements of the Securities Act of 1933, as amended, and the rules and regulations thereunder (the “Securities Act”); (iv) compliance with any applicable requirements of state blue sky or takeover laws and (v) such other consents, approvals, orders, authorizations, notifications, registrations, declarations and filings the failure of which to be obtained or made would not, in the aggregate, reasonably be expected to have a Signature Material Adverse Effect and would not have a material adverse effect on the ability of Signature or Merger Sub, as applicable, to perform its obligations hereunder.
