Placement Agency Agreement

[__], 2024

Lixte Biotechnology Holdings, Inc.

680 East Colorado Boulevard, Suite 180

Pasadena, CA 91101
Attn: Chief Executive Officer

Dear Mr. Bastiaan van der Baan:

This letter (the “Agreement”) constitutes the agreement between WallachBeth Capital LLC (the “Placement Agent”) and Lixte Biotechnology Holdings, Inc., a Delaware corporation (the “Company”), that the Placement Agent shall serve as the exclusive placement agent for the Company, on a reasonable “best efforts” basis, in connection with the proposed offering (the “Placement”) of units (the “Units”), each consisting of one share of common stock, par value $0.0001 per share (the “Common Stock”), or one pre-funded warrant to purchase one share of Common Stock (the “Pre-Funded Warrant”) and one and one-quarter (1.25) common stock purchase warrants to purchase one share of Common Stock (each, a “Common Warrant”, and, together with the Units, Common Stock, and Pre-Funded Warrants, the “Securities”). The Securities actually placed by the Placement Agent are referred to herein as the “Placement Securities.” The Units, the Pre-Funded Warrants, the Common Warrants, and the shares of Common Stock underlying the Pre-Funded Warrants and Common Warrants will be offered and sold under the Company’s registration statement on Form S-1 (File No. 333-282781). The documents executed and delivered by the Company and the Purchasers (as defined below) in connection with the Placement, including, without limitation, a securities purchase agreement (the “Purchase Agreement”), are collectively referred to herein as the “Transaction Documents.”

The terms of the Placement are to be mutually agreed upon by the Company and purchasers signatories to the Purchase Agreement (each, a “Purchaser” and collectively, the “Purchasers”), and nothing herein confers upon the Placement Agent the power or authority to bind the Company or any Purchaser, or constitutes an obligation for the Company to issue any Placement Securities or complete the Placement. The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Securities and does not ensure the successful placement of the Securities, or any portion thereof, or the success of the Placement Agent with respect to securing any other financing on behalf of the Company. The Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement. Certain affiliates of the Placement Agent may participate in the Placement by purchasing some of the Securities. The sale of Securities to any Purchaser will be evidenced by a Purchase Agreement between the Company and such Purchaser in a form reasonably acceptable to the Company and the Purchaser. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

Section 1. Representations and Warranties of the Company; Covenants of the Company.

(a) Representations of the Company. With respect to the Placement Securities, each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement, is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made to, and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that there are no affiliations with any Financial Industry Regulatory Authority, Inc. (“FINRA”) member firm participating in the Placement among the Company’s officers, directors or, to the knowledge of the Company, any five percent (5.0%) or greater security holders of the Company.

(b) Covenants of the Company. The Company covenants and agrees to continue to retain (i) an independent public accounting firm registered with the Public Company Accounting Oversight Board (“PCAOB”) for a period of at least three (3) years after the Closing Date and (ii) a competent transfer agent with respect to the Placement Securities for a period of three (3) years after the Closing Date. In addition, except for an Exempt Issuance, from the date hereof until 45 days after the Closing Date, the Company shall not (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents or (ii) file any registration statement or amendment or supplement thereto, other than filing the final Prospectus or a registration statement on Form S-8 in connection with any employee benefit plan. In addition, from the date hereof until 12 months after the Closing Date, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of shares of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security (other than in connection with a stock split or stock dividend or similar event) or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market offering”, whereby the Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

Section 2. Representations of the Placement Agent. The Placement Agent represents and warrants that it (i) is a member in good standing of FINRA, (ii) is registered as a broker/dealer under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the securities laws of each state in which an offer or sale of Placement Securities is made (unless exempt from the respective state’s broker-dealer registration requirements), (iii) is licensed as a broker/dealer under the laws of the United States of America, applicable to the offers and sales of the Placement Securities by the Placement Agent, (iv) is and will be a corporate body validly existing under the laws of its place of incorporation, and (v) has full power and authority to enter into and perform its obligations under this Agreement. The Placement Agent will immediately notify the Company in writing of any change in its status with respect to subsections (i) through (v) above. The Placement Agent covenants that it will use its reasonable best efforts to conduct the Placement hereunder in compliance with the provisions of this Agreement and the requirements of applicable law.

Section 3. Compensation. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agent and/or its respective designees a cash fee of seven percent (7.0%) of the aggregate purchase price paid by each purchaser of the Placement Securities (the “Cash Fee”). The Placement Agent reserves the right to reduce any item of compensation or adjust the terms thereof as specified herein in the event that a determination is made by FINRA to the effect that the Placement Agent’s aggregate compensation is in excess of that permitted by FINRA Rules or that the terms thereof require adjustment. In addition, on the Closing Date, the Company shall issue to the Placement Agent (or its permitted assignees) warrants to purchase a number of shares of Common Stock equal to an aggregate of 3.0% of the total number of Units sold in this offering, which will have an exercise price equal to 110% of the public offering price per Unit, are exercisable immediately after issuance and will expire five years after the effective date of the registration statement. .

Section 4. Expenses. The Company agrees to pay all costs, fees, and expenses incurred by the Company in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including, without limitation: (i) all expenses incident to the issuance, delivery, and qualification of the Placement Securities (including all printing and engraving costs); (ii) all fees and expenses of the registrar and transfer agent of the Shares; (iii) all necessary issue, transfer, and other stamp taxes in connection with the issuance and sale of the Placement Securities; (iv) all fees and expenses of the Company’s counsel, independent public or certified public accountants, and other advisors; (v) all costs and expenses incurred in connection with the preparation, printing, filing, shipping, and distribution of the Registration Statement (including financial statements, exhibits, schedules, consents, and certificates of experts), the Base Prospectus, and each Prospectus Supplement, and all amendments and supplements thereto, and this Agreement; (vi) all filing fees, reasonable attorneys’ fees, and expenses incurred by the Company in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Placement Securities for offer and sale under the state securities or blue sky laws or the securities laws of any other country; (vii) the fees and expenses associated with including the Placement Securities on the Trading Market; (viii) up to Seventy-Five Thousand Dollars ($75,000) for accountable expenses related to legal fees of counsel to the Placement Agent.

Section 5. Tail Fee. The Placement Agent shall be entitled to compensation under Section 3, calculated in the manner set forth herein with respect to any public or private offering or other financing or capital-raising transaction of any kind (“Tail Financing”) to the extent that such Tail Financing is (i) provided to the Company by investors that were, during the term of this Agreement, introduced to the Company by the Placement Agent for discussions on negotiations regarding the purchase of the Securities and (ii) consummated at any time within the ten (10)-month period following the expiration or termination of this Agreement. The issuance of any stock or equity of the Company to its officers, directors, or employees shall not be deemed a Tail Financing. Upon expiration of this Agreement, the Placement Agent shall provide the Company with a list of all investors whose future investments in the Company will be subject the compensation described in this Section 5. Failure by the Placement Agent to provide such list of investors shall not be deemed a waiver of their right to received compensation pursuant to this Section 5.

Section 5.1. Right of First Refusal. For a period of three (3) months from the Closing Date, the Company hereby grants a right of first refusal to the Placement Agent to act as lead underwriter or book- running manager or placement agent for each and every future public and private equity, equity-linked, convertible or debt (excluding commercial bank debt) offerings of the Company, or any successor to or any subsidiary of the Company during such three (3) month period. If the Placement Agent fails to accept an offer within ten (10) Business Days after the receipt of a notice containing the material terms of a proposed financing by registered mail or overnight courier service addressed to the Placement Agent, then the Placement Agent shall have no further claim or right with respect to the financing proposal contained in such notice. If, however, the terms of such financing proposal are subsequently modified in any material respect, the preferential right referred to herein shall apply to such modified proposal as if the original proposal had not been made. The Placement Agent’s failure to exercise its preferential right with respect to any particular proposal shall not affect its preferential rights relative to future proposals.

Section 6. Indemnification.

(a) To the extent permitted by law, with respect to the Placement Securities, the Company shall indemnify the Placement Agent and its affiliates, stockholders, directors, officers, employees, members, and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) against all losses, claims, damages, expenses, and liabilities, as the same are incurred (including reasonable actual and documented fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to this Agreement, except to the extent that any losses, claims, damages, expenses, or liabilities (or actions in respect thereof) are found in a final judgment (not subject to appeal) by a court of law to have resulted primarily and directly from the Placement Agent’s willful misconduct or gross negligence in performing the services described herein. Notwithstanding anything set forth herein to the contrary, the Company agrees to indemnify the Placement Agent, to the fullest extent set forth in this Section 6, against any and all claims asserted by any or person or entity alleging that the Placement Agent was not permitted or entitled to act as a placement agent herein, or that the Company was not permitted to hire or retain the Placement Agent herein, including but not limited to any claims arising out of any purported right of first refusal another person or entity claims to have to act as a placement agent or any similar role with respect to the Company or its securities.

(b) Promptly after receipt by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent is entitled to indemnity hereunder, the Placement Agent will immediately notify the Company in writing of such claim or of the commencement of such action or proceeding, but failure or delay of notification to so notify the Company shall not relieve the Company from any obligation it may have hereunder, except and only to the extent such failure results in the forfeiture by the Company of substantial rights and defenses or materially adversely impacts the Company. If the Company so elects or is requested by the Placement Agent, the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to the Placement Agent and will pay the reasonable fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement Agent will be entitled to employ its own counsel separate from counsel for the Company and from any other party in such action if counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company, in addition to reasonable fees of local counsel. The Company will have the right to settle the claim or proceeding, provided that the Company will not settle any such claim, action, or proceeding without the prior written consent of the Placement Agent, which will not be unreasonably withheld. The Company will not be liable for settlement of any action effected without its written consent, which may not be unreasonably withheld, conditioned, or delayed.

(c) The Company agrees to notify the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to a transaction contemplated by this Agreement.

(d) If for any reason the foregoing indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute to the amount paid or payable by the Placement Agent as a result of such losses, claims, damages, or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Placement Agent on the other, but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims, damages, or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages, and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding, or other action or claim. Notwithstanding the provisions hereof, the Placement Agent’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under this Agreement (excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

(e) The provisions of this Section 6 will remain in full force and effect, survive the expiration or termination of this Agreement, and be in addition to any liability that the Company might otherwise have to any indemnified party under this Agreement, whether or not the transaction contemplated by this Agreement is completed.

Section 7. Engagement Term. The Placement Agent’s engagement hereunder will be until the earlier of (i) [__], 2024, and (ii) the Closing Date (such earlier date, the “Termination Date”); provided, however, the Placement Agent may terminate this Agreement prior to the Termination Date if it reasonably determines that it is unsatisfied with the results of its due diligence investigation, notwithstanding its best efforts to complete the Placement. The Company may terminate the engagement hereunder for any reason prior to the Termination Date. If this Agreement expires or terminates prior to the completion of the Placement, the Company shall reimburse expenses incurred by the Placement Agent, pursuant to Section 4 hereof but in no event greater than the amounts set forth in Section 4, up to and including the date of Termination. The Placement Agent may not use any confidential information concerning the Company provided by the Company for any purposes other than those contemplated under this Agreement.

Section 8. Placement Agent Information. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

Section 9. No Fiduciary Relationship. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not a party hereto, except those entitled hereto by virtue of the indemnification provisions hereof. The Company acknowledges and agrees that the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of the Placement Agent hereunder, all of which are hereby expressly waived.

Section 10. Closing. The obligations of the Placement Agent, and the closing of the sale of the Placement Securities hereunder are subject to the accuracy, when made and on the Closing Date, of the representations and warranties on the part of the Company contained herein and in the Purchase Agreement, to the performance by the Company of its obligations hereunder and in the Purchase Agreement, and to each of the following additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the Placement Agent:

(a) All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery, and validity of each of this Agreement, the Placement Securities, and all other legal matters relating to this Agreement and the transactions contemplated hereby with respect to the Placement Securities have been completed or resolved in a manner reasonably satisfactory in all material respects to the Placement Agent.

(b) The Placement Agent has received from outside legal counsel, including local counsel, if applicable, to the Company such counsel’s written opinion and negative assurance letter with respect to the Placement Securities, addressed to the Placement Agent and dated as of the Closing Date, in form and substance reasonably satisfactory to the Placement Agent.

(c) The Placement Agent has received customary certificates of the Company’s executive officers (the “Officer’s Certificate”) as to the accuracy of the representations and warranties contained in the Purchase Agreement, and a certificate of the Company’s secretary (the “Secretary’s Certificate”) certifying (i) that the Company’s organizational documents are true and complete, have not been modified and are in full force and effect; (ii) that the resolutions of the Company’s Board of Directors relating to the Placement are in full force and effect and have not been modified; and (iii) as to the incumbency of the officers of the Company. Each of the Officer’s Certificate and Secretary’s Certificate must be dated as of the Closing Date, and all documents referenced in the Secretary’s Certificate must be attached thereto.

(d) The Common Stock has been registered under the Exchange Act and listed, admitted and authorized for trading on the Trading Market or other applicable U.S. national exchange as of the Closing Date, and the Placement Agent has received reasonably satisfactory evidence of such actions. The Company has not taken any action designed to, or likely to have the effect of terminating the registration of the Common Stock under the Exchange Act or delisting, or suspending from trading, the Common Stock from the Trading Market or other applicable U.S. national exchange. The Company has not received any information suggesting that the Commission or the Trading Market or other U.S. applicable national exchange is contemplating terminating such registration or listing.

(e) No action or proceeding before a court of competent jurisdiction has been taken, and no statute, rule, regulation, or order has been enacted, adopted or issued by any governmental agency or body that would, as of the Closing Date, prevent the issuance or sale of the Placement Securities or materially and adversely affect the business or operations of the Company. No injunction, restraining order, or order of any other nature by any federal or state court of competent jurisdiction has been issued as of the Closing Date that would prevent the issuance or sale of the Placement Securities or materially and adversely affect the business or operations of the Company.

(f) The Company has entered into a Purchase Agreement with each of the Purchasers of the Placement Securities, and such agreements are in full force and effect and contain representations, warranties and covenants of the Company as agreed upon between the Company and the Purchasers.

(g) FINRA raised no objections to the fairness and reasonableness of the terms and arrangements of this Agreement. If requested by the Placement Agent, the Company has filed, or has authorized the Placement Agent’s counsel to file on the Company’s behalf, with FINRA all necessary materials in compliance with FINRA Rule 5110 with respect to the Placement and has paid all filing fees required in connection therewith.

(h) The Placement Agent has received an executed Lock-Up Agreement from each of the Company’s officers, directors prior to the Closing Date.

(i) On or before the Closing Date, the Placement Agent and counsel for the Placement Agent have received such information and documents as they may reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Placement Securities as contemplated herein, or in order to evidence the accuracy of any of the representations and warranties of the Company, or the satisfaction of any of the conditions or agreements, herein contained.

(j) On the date hereof, the Placement Agent shall have received, and the Company shall have caused to be delivered to the Placement Agent, letters from both Weinberg & Company, P.A. (the independent registered public accounting firm of the Company), addressed to the Placement Agent, dated as of the date hereof, in form and substance satisfactory to the Placement Agent. The letter shall not disclose any change in the condition (financial or other), earnings, operations, or business of the Company, which, in the Placement Agent’s sole judgment, is material and adverse and that makes it, in the Placement Agent’s sole judgment, impracticable or inadvisable to proceed with the Placement of the Securities.

(k) The Placement Agent shall have received from the Company a certificate by the Chief Financial Officer of the Company, dated as of such date, in form and substance reasonably satisfactory to the Placement Agent.

Any such oral notice must be promptly confirmed in writing.

Section 11. Governing Law. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely in such State.

Any right to trial by jury with respect to any dispute arising under this Agreement or any transaction or conduct in connection herewith is waived.
