up to its Pro Rata Share of New Securities which Ensysce or the Company may, from time to time, propose to sell and issue in any
Applicable Participating Right Financing commenced during the Participation Right Period.


 


2.2
Exercise of Participation Right. If, and each time during the Participation Rights Period, Ensysce or the Company proposes
to undertake an Applicable Participation Right Financing, Ensysce or the Company, as appropriate, shall give each Investor written
notice of its intention, describing the type of New Securities and their price and general terms upon which Ensysce or the Company
proposes to issue the same. Each Investor shall have ten (10) calendar days after any such notice is mailed or delivered to agree
to purchase, and purchase, up to such Investor’s Pro Rata Share of such New Securities for the price and on the terms specified
in the notice by giving written notice to Ensysce or the Company, as appropriate, in substantially the form attached hereto as
Exhibit A, and stating the quantity of New Securities to be purchased.


 


ARTICLE
III.

RIGHT OF FIRST REFUSAL


 


3.1
Grant. Ensysce hereby grants to each Investor the right of first refusal (the “ROFR”)
to purchase its Pro Rata Share of New Securities which the Company may, from time to time, propose to sell and issue in a ROFR
Eligible Financing.


 


3.2
Exercise of ROFR. (a) If, and each time during the ROFR Period, the Company proposes to undertake a ROFR Eligible Financing,
it shall give each Investor written notice of its intention, describing the type of New Securities and their price and general
terms upon which the Company proposes to issue the same. Each Investor shall have twenty (20) calendar days after any such notice
is mailed or delivered to agree to purchase, and purchase, such Investor’s Pro Rata Share of such New Securities for the
price and on the terms specified in the notice by giving written notice to the Company, in substantially the form attached hereto
as Exhibit A, and stating the quantity of New Securities to be purchased. In the event that some, but not all, Investors
elect to fully exercise the ROFR, at the expiration of such twenty (20) day period, the Company shall promptly notify each Investor
that elected to fully exercise the ROFR (each, a “Fully Exercising Investor”) of any other Investor’s
failure to fully exercise the ROFR. During the ten (10) calendar period commencing after the Company has given such notice, each
Fully Exercising Investor may, by giving notice to the Company, elect to purchase (the “Overallotment Right”),
in addition to the number of shares specified above, up to their Pro Rata Share of the New Securities for which Investors were
entitled to subscribe pursuant to the ROFR but that were not subscribed.

(b)
In the event the Investors fail to exercise fully the ROFR within said period described in Section 3.1(a) (the “Election
Period”), the Company shall have ninety (90) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all, within thirty (30) days from the date of said agreement)
to sell that portion of the New Securities with respect to which the Investors’ ROFR option set forth in Section 3.1 was
not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice
to Investors delivered pursuant to Section 3.2. In the event the Company has not sold within such ninety (90) day period following
the Election Period, or such thirty (30) day period following the date of said agreement, the Company shall not thereafter issue
or sell any New Securities in a ROFR Eligible Financing without first again offering such securities to the Investors in the manner
provided in Section 3.1.

deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language
chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. This
Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring
or disfavoring any party by virtue of the authorship of any provisions of this Agreement.


 


4.4
Successors and Assigns. The provisions of this Agreement shall inure to the benefit of and be binding upon the parties
and their successors and permitted assigns, it being specifically agreed, that, upon closing of a Reverse Merger, all rights and
obligations of Ensysce hereunder shall be specifically assigned to and assumed by the Company. This Agreement, or any rights or
obligations hereunder, may not be assigned by Ensysce or the Company, as appropriate, without the prior written consent of the
Investors. Any Investor may assign its rights hereunder in whole or in part to any person to whom such Investor assigns or transfers
any Convertible Notes in compliance with the SPA and applicable law, provided such transferee shall agree in writing to

to include in the merger agreement with respect any Reverse Merger, a requirement that, effective on closing of the Reverse Merger,
all obligations of Ensysce contained herein shall be assumed and carried out by the Company.


 


4.5
No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person.


 


4.6
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall
be governed by and construed and enforced in accordance with the internal laws of the State of California, without regard to the
principles of conflicts of law thereof. Each party agrees that all Actions concerning the interpretations, enforcement and defense
of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, employees
or agents) shall be commenced exclusively in the California Courts. Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the California Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any Action, any claim that
it is not personally subject to the jurisdiction of any such California Court, or that such Action has been commenced in an improper
or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served
in any such Action by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to
serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY. If either party shall commence an Action to enforce any provisions of this Agreement,
then the prevailing party in such Action shall be reimbursed by the other party for its reasonable attorney’s fees and other

4.7
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other
party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered
by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid
and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as
if such facsimile or e-mail signature page were an original thereof.


 


4.8
Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and
the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.
