At any time, and from time to time, on or after a Qualifying Financing, the Investor may, at its sole and exclusive option, convert all or any part of the principal (and accrued and unpaid interest) outstanding under this Note into Qualifying Securities issued in a Qualifying Financing of Ensysce at a conversion price, subject to adjustment as provided in Section 6 (the “Base Conversion Price”) per share of Qualifying Securities equal to fifty percent (50%) of the Applicable Price. For purposes hereof, (i) a “Qualifying Financing” shall mean the first sale and issuance, after the date of this Note and for cash, by Ensysce of Qualifying Securities in a single transaction, or series of related transactions on the same terms, in an aggregate amount not less than five million dollars ($5,000,000); (ii) “Qualifying Securities” shall mean Ensysce common stock, preferred stock or any securities conferring the right to purchase Ensysce common stock, preferred stock or securities convertible into, or exchangeable for (with or without additional consideration), Ensysce common stock or preferred stock, except that such defined term shall not include the Notes or any security (x) granted, issued and/or sold by Ensysce to any employee, director or consultant in such capacity, or (y) issued upon the conversion or exercise of any option, warrant or other security outstanding as of the date of this Note; and (iii) “Applicable Price” shall mean the price per share of Qualifying Securities paid in the Qualifying Financing.

(b) Automatic Conversion. At the closing date of a Going Public Transaction, the entire principal outstanding under this Note (and accrued and unpaid interest) shall be automatically converted into shares of common stock (the “Common Stock”) of the Public Company at a conversion price per share equal to the Automatic Conversion Price. For purposes hereof, (i) a “Going Public Transaction” shall mean (A) an initial public offering (the “IPO”) of Common Stock by Ensysce, or (B) a merger, acquisition, reorganization or similar transaction (a “Reverse Merger”) that results in the holders of Ensysce common stock holding Listed Shares of the Public Company; (ii) the “Public Company” shall mean (A) in the case of an IPO, Ensysce; and (B) in the case of a Reverse Merger, the party to the Reverse Merger whose shares are issued in the Reverse Merger and which shares comprise Listed Shares; (iii) “Listed Shares” shall mean shares of equity securities of the Public Company that are traded on a recognized U.S. securities trading market or exchange; (iv) “Automatic Conversion Price” shall mean a price per share equal to the lesser of (A) the Maximum Agreed Per Share Price, or (B) the Agreed EVPS; (v) “Maximum Agreed Per Share Price” shall mean, subject to adjustment as provided in Section 6 hereof, $0.25 per share; (vi) “Agreed EVPS” shall mean the Enterprise Value per share of the Public Company’s common stock as measured on the Measurement Date; (vii) “Enterprise Value” shall mean, with respect to the Public Company and as measured on the Measurement Date, the Market Capitalization + Debt + Preferred Stock - Cash and Cash Equivalents; provided, that for purposes of computing Agreed EVPS, Enterprise Value shall not exceed $55,000,000; (viii) “Market Capitalization” shall mean, as of the Measurement Date, the total number of issued and outstanding shares of common stock of the Company multiplied by (A) in the case of an IPO, the price of the Listed Shares sold in the IPO, and (B) in the case of a Reverse Merger, the closing price of the Public Company’s common stock on the Principal Market; (ix) “Measurement Date” shall mean (A) in the case of an IPO, the closing date of the IPO, and (B) in the case of a Reverse Merger, the first trading day, on which the Common Stock trades on the Principal Market, closing after the public announcement of completion of the Reverse Merger (for clarity, if the Reverse Merger is announced during a trading day but before the close of the trading market on that day, the day of such announcement shall be the Measurement Date; if the Reverse Merger is announced after the close of a trading, the following trading day shall be the Measurement Date); and (xi) “Principal Market” shall mean the principal U.S. stock exchange or over-the-counter market on which the Common Stock trades on the Measurement Date;

(c) Mechanics and Effect Of Conversion. No fractional shares of Qualifying Securities or Common Stock, as appropriate, shall be issued upon conversion of this Note, in part or in whole. Fractional shares otherwise issuable on conversion shall be rounded down to the highest whole number of shares. On partial conversion of this Note, Ensysce shall issue to the Investor (i) the shares of Qualifying Securities into which a portion of this Note is converted and (ii) a new convertible promissory note having identical terms to this Note, except that the principal amount thereof shall equal the difference between (A) the principal amount of this Note immediately prior to such conversion minus (B) the portion of such principal amount converted into stock. Upon conversion of this Note, the Investor shall surrender this Note, duly endorsed, at the principal office of Ensysce. At its expense, Ensysce or the Company, as appropriate, shall, as soon as practicable following conversion pursuant to Section 5(a) or 5(b), as appropriate, issue and deliver to the Investor a certificate or certificates for the number of shares of Qualifying Securities or Common Stock, as appropriate, to which the Investor shall be entitled upon such conversion (bearing such legends as arc required by applicable state and federal securities laws in the opinion of counsel to Ensysce or the Company, as appropriate), together with any other securities and property to which the Investor is entitled upon such conversion under the terms of this Note.

(d) Reservation Of Stock Issuable Upon Conversion. Ensysce shall at all times reserve and keep available, out of its authorized but unissued shares of capital stock, solely for the purpose of effecting the conversion of this Note, such number of its shares of its capital stock as shall from time to time be sufficient to effect the conversion of this Note; and if at any time the number of authorized but unissued shares of capital stock of Ensysce shall not be sufficient to effect the conversion of this Note, Ensysce hereby covenants and agrees to take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of capital stock to such number of shares as shall be sufficient for such purpose. As a condition of the Investor’s purchase of this Note, Ensysce shall include in any merger agreement pertaining to a Reverse Merger a requirement that the Company will assume the conversion obligations under this Note and reserve and keep available, out of its authorized but unissued shares of capital stock, solely for the purpose of effecting the conversion of this Note, such number of shares of its capital stock as shall from time to time be sufficient to effect the conversion of this Note.

(e) Payment Of Expenses And Taxes On Conversion. Ensysce or, on and after a Reverse Merger, the Public Company, shall pay all expenses, taxes and other charges payable in connection with the preparation, execution, issuance and delivery of stock certificates and new promissory notes pursuant to this Section 5 hereof.

(f) Sale of Ensysce. Notwithstanding any provision in this Note to the contrary, in the event Ensysce consummates a Company Sale prior to the conversion or repayment in full of this Notes, (i) Ensysce will give the Holder at least five days prior written notice of the anticipated closing date of such Company Sale and (ii) at the closing of such Company Sale, in lieu of the principal and interest that would otherwise be payable at such date, Ensysce will have the right, subject to the Holder’s continuing right to convert hereunder prior to that date, to pay the Holders, in full satisfaction of Ensysce’s obligations under this Note, an aggregate equal to (x) two times the aggregate amount of principal then outstanding under this Note, plus (y) all then accrued and unpaid interest on this Note. For purposes hereof, “Company Sale” shall mean (i) any transaction or series of related transactions to which Ensysce is a party in which in excess of 50% of Ensysce’s voting power is transferred; or (ii) a sale, lease or other disposition of all or substantially all of the assets of Ensysce; provided, however, that a Company Sale shall not include (x) a transaction qualifying as a Going Public Transaction; or (y) any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by Ensysce or indebtedness of Ensysce is cancelled or converted.

Section 6. Conversion Price Adjustments.

(a) Adjustment For Stock Splits. If Ensysce shall, at any time or from time to time after the occurrence of a Qualifying Financing, effect a stock split or subdivision of its outstanding common stock (excluding stock splits or stock subdivisions effected pursuant to the terms of a Reverse Merger), the Base Conversion Price in effect immediately before that subdivision shall be proportionately decreased, effective at the close of business on the date the stock split or subdivision becomes effective.

(b) Adjustment For Stock Combinations. If Ensysce shall, at any time or from time to time after the occurrence of a Qualifying Financing, combine the outstanding shares of its common stock (including by way of reverse stock split) into a smaller number of shares (excluding a combination effected pursuant to the terms of a Reverse Merger), the Base Conversion Price in effect immediately before the combination shall be proportionately increased, effective at the close of business on the date the combination becomes effective.

(c) Adjustment for Stock Splits and Combinations Pursuant to a Reverse Merger. If, pursuant to the terms of a Reverse Merger, a stock split or subdivision of the Common Stock of the Company is effected resulting in the total outstanding shares of Common Stock exceeding the number that would otherwise be outstanding on the closing date of the Reverse Merger, the Maximum Agreed Per Share Price shall be proportionately decreased. Conversely, if, pursuant to the terms of a Reverse Merger, a combination of the Common Stock of the Company is effected (including by way of a reverse stock split) resulting in the total outstanding shares of Common Stock being less than the number that would otherwise be outstanding on the closing date of the Reverse Merger, the Maximum Agreed Per Share Price shall be proportionally increased.

(d) Adjustment For Common Stock Dividends And Distributions. If Ensysce, at any time or from time to time after the occurrence of a Qualifying Financing, issues, or fixes a record date for the determination of holders of common stock entitled to receive, a dividend or other distribution payable solely in additional shares of common stock, the Base Conversion Price that is then in effect shall be decreased as of the time of such issuance or, in the event such record date is fixed, as of the close of business on such record date, by multiplying the Base Conversion Price by a fraction (i) the numerator of which is the total number of shares of common stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (ii) the denominator of which is the sum of the total number of shares of common stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of common stock issuable in payment of such dividend or distribution; provided, however, that if such record date is fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Base Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Base Conversion Price shall be adjusted pursuant to this Section 6(d) to reflect the actual payment of such dividend or distribution.

(e) Adjustments For Other Dividends And Distributions. If Ensysce, at any time or from time to time after the occurrence of a Qualifying Financing, issues, or fixes a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of Ensysce (other than shares of common stock) or in other property, in each such event provision shall be made so that the Investor shall receive upon conversion hereof, in addition to the number of shares of common stock receivable hereupon, the amount of securities of Ensysce or other property which such Investor would have received had this Note been converted into common stock on the date of such event and had it thereafter, during the period from the date of such event to and including the conversion date, retained such securities or other property receivable by it as aforesaid during such period, subject to all other adjustments called for during such period under this Section 6 with respect to the rights of the Investor or with respect to such other securities or other property by their terms. As used herein, the term “other property” does not include cash.

(f) Adjustment For Reclassification, Exchange And Substitution. If at any time or from time to time after the occurrence of a Qualifying Financing, the Qualifying Securities issuable upon the conversion of this Note are changed into the same or a different number of shares of any class or series of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination of shares or stock dividend or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this Section 6), then in any such event the Investor shall have the right thereafter to convert this Note into the kind and amount of stock and other securities and property receivable upon such recapitalization, reclassification or other change by holders of the number of shares of Qualifying Securities into which this Note could have been converted immediately prior to such recapitalization, reclassification or change, all subject to further adjustment as provided herein or with respect to such other securities or property by the terms thereof.

(g) Certificate Of Adjustment. In each case of an adjustment or readjustment of the Base Conversion Price or Maximum Agreed Per Share Price pursuant to this Section 6, Ensysce, at its own expense, shall cause its Treasurer to compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such adjustment or readjustment, and shall mail such certificate, by first class mail, postage prepaid, to the Investor at the Investor’s address as shown in Ensysce’s books. The certificate shall set forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based. No adjustment in the Base Conversion Price or Maximum Agreed Per Share Price shall be required to be made unless it would result in an increase or decrease of at least one cent, but any adjustments not made because of this sentence shall be carried forward and taken into account in any subsequent adjustment otherwise required hereunder.

(h) Notices Of Record Date. Upon (i) the establishment by Ensysce of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or (ii) any capital reorganization of Ensysce, any reclassification or recapitalization of the capital stock of Ensysce, any merger or consolidation of Ensysce with or into any other company, or any transfer of all or substantially all the assets of Ensysce to any other person or any voluntary or involuntary dissolution, liquidation or winding up of Ensysce, Ensysce shall mail to the Investor at least 10 days prior to the record date specified therein a notice specifying (A) the date on which any such record is to be taken for the purpose of such dividend or distribution and a description of such dividend or distribution, (B) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up is expected to become effective, and (C) the date, if any, that is to be fixed as to when the holders of record of common stock (or other securities) of Ensysce, shall be entitled to exchange their shares of common stock (or other securities), for securities or other property deliverable upon such reorganization, reclassification transfer, consolidation, merger, dissolution, liquidation or winding up.

(i) No Impairment. Ensysce shall not amend its Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by Ensysce, but shall at all times in good faith assist in carrying out all such action as may be reasonably necessary or appropriate in order to protect the conversion rights of the Investor against dilution or other impairment as provided herein.

This Note is an unsecured general obligation of Ensysce.

Section 8. Defenses.

(b) Upon receipt by Ensysce of evidence satisfactory to it of the loss, theft, destruction, or mutilation of this Note and (in the case of loss, theft or destruction) of an indemnity reasonably satisfactory to it, and upon surrender and cancellation of this Note, if mutilated, Ensysce will deliver a new Note of like tenor in lieu of this Note. Any Note delivered in accordance with the provisions of this Section 9 shall be dated as of the date of this Note.

Ensysce hereby waives presentment, demand for payment, notice of dishonor, notice of protest and all other notices or demands in connection with the delivery, acceptance, performance or default of this Note.
