EMMAUS LIFE SCIENCES, INC.

Common Stock Purchase Warrant

THIS CERTIFIES THAT, for value received, Crystal Research Associates, LLC, a limited liability company, or registered assigns (the “Holder”), is entitled to subscribe for and purchase, at the Exercise Price (as defined below), from Emmaus Life Sciences, Inc., a Delaware corporation (the “Company”), shares of the Company’s common stock, par value $0.001 (the “Common Stock”), at any time from January 27, 2023 and prior to 5:00 p.m., New York time, on January 26 2028 (the “Warrant Exercise Term”).

This Warrant is issued in accordance with the Letter of Agreement dated September 22, 2022, between the Holder and the Company.

This Warrant is subject to the following terms and conditions:

1. Shares. The Holder has, subject to the terms set forth herein, the right to purchase up to an aggregate of 500,000 shares of Common Stock (the “Warrant Shares”) at a per share exercise price of $0.47, subject to adjustment as provided for herein (the “Exercise Price”).

2. Exercise of Warrant.

(a) Exercise. This Warrant may be exercised by the Holder at any time during the Warrant Exercise Term, in whole or in part, by delivering the notice of exercise attached as Exhibit A hereto (the “Notice of Exercise”), duly executed by the Holder to the Company at its principal office, or at such other office as the Company may designate, accompanied by payment, by wire transfer of immediately available funds to the order of the Company to an account designated by the Company, of the amount obtained by multiplying the number of Warrant Shares designated in the Notice of Exercise by the Exercise Price (the “Purchase Price”). For purposes hereof, “Exercise Date” shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant to this Section 2(a) shall have been made. The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. No originals of the Notice of Exercise shall be required to be delivered, nor shall any medallion guarantee (or any other type of guarantee or notarization) of any Notice of Exercise be required.

(b) Issuance of Certificates. As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof (and in no event later than two (2) Trading Days following the delivery of the Notice of Exercise), the Company, at its expense, shall cause to be issued in the name of and delivered to the Holder: (i) a certificate or certificates for (or, if applicable, by delivery through the facilities of the Depository Trust Company in electronic form of) the number of fully paid and non-assessable Warrant Shares to which the Holder shall be entitled upon such exercise and, if applicable, (ii) a new warrant of like tenor to purchase all of the Warrant Shares that may be purchased pursuant to the portion, if any, of this Warrant not exercised by the Holder. The Holder shall for all purposes hereof be deemed to have become the Holder of record of such Warrant Shares on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2(a) hereof were delivered and made, respectively, irrespective of the date of delivery of such certificate or certificates, except that if the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of record of such Warrant Shares at the close of business on the next succeeding date on which the stock transfer books are open.

(c) Taxes. The issuance of the Warrant Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such Warrant Shares, shall be made without charge to the Holder for any tax or other charge of whatever nature in respect of such issuance and the Company shall bear any such taxes in respect of such issuance.

3. Adjustment of Exercise Price.

(a) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of shares of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding shares of Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the shares of Common Stock or any compulsory stock exchange pursuant to which the shares of Common Stock are effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of shares of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in customary form and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

2

(b) Adjustments for Split, Subdivision or Combination of Shares. If while this Warrant, or any portion hereof, remains outstanding and unexpired the Company shall subdivide (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition hereunder, then, upon the effective date of such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant will be proportionately increased. If the Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition hereunder, then, upon the effective date of such combination, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant will be proportionately decreased.

(c) Notice of Adjustments. Upon any adjustment of the Exercise Price and any increase or decrease in the number of Warrant Shares purchasable upon the exercise of this Warrant, then, and in each such case, the Company, within 15 days thereafter, shall give written notice thereof to the Holder at the address of such Holder as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and, if applicable, the increased or decreased number of Warrant Shares purchasable upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation of each.

4. Notices. Any notice or other communication required or permitted to be given hereunder shall be in writing and shall be delivered in accordance with Exhibit A to this Warrant.

5. Legends. Unless the Warrant Shares are registered for resale with the Commission, each certificate evidencing the Warrant Shares issued upon exercise of this Warrant shall be stamped or imprinted with the following legend:

THIS SECURITY AND THE SECURITIES FOR WHICH THIS SECURITY IS EXERCISABLE HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

6. Removal of Legend. Upon request of a holder of a certificate with the legends required by Section 5 hereof, the Company shall issue to such holder a new certificate therefor free of any transfer legend, if, with such request, the Company shall have received an opinion of counsel satisfactory to the Company in form and substance to the effect that any transfer by such holder of the Warrant Shares evidenced by such certificate will not violate the Securities Act or any applicable state securities law.

7. Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise hereunder. Instead, the Company shall round up, as nearly as practicable to the nearest whole Share, the number of Warrant Shares to be issued.

3

8. Rights of Stockholders. Except as expressly provided herein, the Holder, as such, shall not be entitled to vote or be deemed the holder of the Warrant Shares or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or otherwise until this Warrant shall have been exercised and the Warrant Shares purchasable upon the exercise hereof shall have been issued, as provided herein.

9. Transferability.

(a) This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent and funds sufficient to pay any transfer taxes payable upon the making of such transfer. In connection with any transfer other than pursuant to an effective Registration Statement or Rule 144, to the Company or to an Affiliate of the Holder, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b) This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 9(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the original issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

(c) The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

10. Miscellaneous.

(a) This Warrant and disputes arising hereunder shall be governed by and construed and enforced in accordance with the laws of the State of Delaware applicable to agreements made and to be performed wholly within such State, without regard to its conflict of law rules. Any action brought by either party against the other concerning the transaction contemplated by this Warrant shall be brought only in the state courts of Delaware or in the federal courts located in the state of Delaware. The parties to this Warrant hereby irrevocably waive any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. The Company and Holder waive trial by jury.

(b) The headings in this Warrant are for purposes of reference only and shall not limit or otherwise affect any of the terms hereof.

(c) The covenants of the respective parties contained herein shall survive the execution and delivery of this Warrant.

(d) The terms of this Warrant shall be binding upon and shall inure to the benefit of any successors or permitted assigns of the Company and of the Holder and of the Warrant Shares issued or issuable upon the exercise hereof.

(e) This Warrant and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subject hereof.

(f) The Company shall not, by amendment of its Certificate of Incorporation or Bylaws, or through any other means, directly or indirectly, avoid or seek to avoid the observance or performance of any of the terms of this Warrant and shall at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder contained herein against impairment.

(g) Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company, or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Company, at its expense, will execute and deliver to the Holder, in lieu thereof, a new Warrant of like date and tenor.

(h) This Warrant and any provision hereof may be amended, waived or terminated only by an instrument in writing signed by the Company and the Holder.

(i) The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.
