THIS CERTIFIES THAT, in consideration of funds duly paid by or on behalf of _______________ (the “Holder”), as registered owner of this warrant to purchase shares of Common Stock (as defined below (the “Purchase Warrant”), to OS Therapies Incorporated, a Delaware corporation (the “Company”), the Holder is entitled, at any time or from time to time beginning [●], 2024¹ (the “Commencement Date”), and at or before 5:00 p.m., Eastern time, on [●], 2029² (the “Expiration Date”), but not thereafter, to subscribe for, purchase and receive, in whole or in part, up to [●] shares (the “Shares”) of common stock of the Company, par value $0.001 per share (the “Common Stock”), subject to adjustment as provided in Section 6 hereof.

¹ INSERT DATE 180 DAYS AFTER COMMENCMENT OF SALES DATE.

² INSERT DATE 5 YEARS AFTER COMMENCEMENT OF SALES DATE.

2. Exercise.

2.1 Exercise Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase Warrant and, subject to Section 2.2, payment of the Exercise Price for the Shares being purchased payable in cash by wire transfer of immediately available funds to an account designated by the Company or by certified check or official bank check. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase Warrant shall become and be void without further force or effect, and all rights represented hereby shall cease and expire. Each exercise hereof shall be irrevocable.

2.2 Cashless Exercise. In lieu of exercising this Warrant by delivering the aggregate Exercise Price by wire transfer or cashier’s check at the election of the Holder, this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder may elect to receive the number of Shares equal to the value of this Purchase Warrant (or the portion thereof being exercised), by surrender of this Purchase Warrant to the Company, together with the exercise form attached hereto, in which event the Company will issue to Holder Shares in accordance with the following formula:

	X	=	Y(A-B)
			A

Where,
	X	=	The number of Shares to be issued to Holder;
	Y	=	The number of Shares for which the Purchase Warrant is being exercised;
	A	=	The fair market value of one Share; and
	B	=	The Exercise Price.

For purposes of this Section 2.2, the fair market value of a Share is defined as follows:

(i) if the Company’s Common Stock is traded on a national securities exchange, the OTCQB or OTCQX, the fair market value shall be deemed to be the closing price on such exchange, the OTCQB or OTCQX, as the case may be, on the Business Day immediately preceding the date that the exercise form is delivered pursuant to Section 8.4 in connection with the exercise of the Purchase Warrant; or

(ii) if the Company’s Common Stock is not then traded on a national securities exchange, the OTCQB or OTCQX and if prices for the Company’s Common Stock are then reported on the “Pink Sheets” published by OTC Markets Group, Inc., the fair market value shall be deemed to be the closing bid prior to the exercise form being submitted in connection with the exercise of the Purchase Warrant so reported; provided, however, if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Company’s Board of Directors.

If Shares are issued pursuant to this Section 2.2, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”), the Shares shall take on the characteristics of the Purchase Warrant, and the holding period of the Shares being issued may be tacked on to the holding period of this Purchase Warrant for purposes of Rule 144 promulgated under the Securities Act (“Rule 144”). The Company agrees not to take any position contrary to this Section 2.2.

2

2.3 Legend. Each certificate for the securities purchased under this Purchase Warrant shall bear a legend as follows unless such securities have been registered under the Securities Act:

The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or applicable state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from registration under the Securities Act and applicable state law which, in the opinion of counsel to the Issuer, is available.

2.4 Resale of Shares. Holder and the Company acknowledge that as of the date hereof the Staff of the Division of Corporation Finance of the U.S. Securities and Exchange Commission (the “Commission”) has published Compliance & Disclosure Interpretation 528.04 in the Securities Act Rules section thereof, stating that the holder of securities issued in connection with a public offering may not rely upon Rule 144 to establish an exemption from registration requirements under Section 4(a)(1) of the Securities Act, but may nonetheless apply Rule 144 constructively for the resale of such shares in the following manner: (a) provided that six (6) months has elapsed since the last sale under the registration statement, an underwriter or finder may resell the securities in accordance with the provisions of Rule 144(c), (e), and (f), except for the notice requirement; (b) a purchaser of the shares from an underwriter receives restricted securities unless the sale is made with an appropriate, current prospectus, or unless the sale is made pursuant to the conditions contained in (a) above; (c) a purchaser of the shares from an underwriter who receives restricted securities may include the underwriter’s holding period, provided that the underwriter or finder is not an affiliate of the issuer; and (d) if an underwriter transfers the shares to its employees, the employees may tack the firm’s holding period for purposes of Rule 144(d), but they must aggregate sales of the distributed shares with those of other employees, as well as those of the underwriter or finder, for a six-month period from the date of the transfer to the employees. Holder and the Company also acknowledge that the Staff of the Division of Corporation Finance of the Commission has advised in various no-action letters that the holding period associated with securities issued without registration to a service provider commences upon the completion of the services, which the Company agrees and acknowledges shall be the final closing of the Offering, and that Rule 144(d)(3)(ii) provides that securities acquired from the issuer solely in exchange for other securities of the same issuer shall be deemed to have been acquired at the same time as the securities surrendered for conversion (which the Company agrees is the date of the initial issuance of this Purchase Warrant). In the event that following a reasonably-timed written request by Xxxxxx to transfer the Shares in accordance with Compliance & Disclosure Interpretation 528.04 counsel for the Company in good faith concludes that Compliance & Disclosure Interpretation 528.04 no longer may be relied upon as a result of changes in applicable laws, regulations, or interpretations of the Division of Corporation Finance, or as a result of judicial interpretations not known by the Company or its counsel on the date hereof, then the Company shall promptly, and in any event within five (5) Business Days following the request, provide written notice to Holder of such determination. As a condition to giving such notice, the parties shall negotiate in good faith a single demand registration right pursuant to an agreement in customary form reasonably acceptable to the parties; provided that notwithstanding anything to the contrary, the obligations of the Company pursuant to this Section 2 shall terminate on the fifth (5^th) anniversary of the Initial Exercise Date. In the absence of such conclusion by counsel for the Company, the Company shall, upon such a request of Holder given no earlier than six (6) months after the final closing of the Offering, instruct its transfer agent to permit the transfer of such shares in accordance with Compliance & Disclosure Interpretation 528.04, provided that Holder has provided such documentation as shall be reasonably be requested by the Company to establish compliance with the conditions of Compliance & Disclosure Interpretation 528.04. Notwithstanding anything to the contrary, pursuant to FINRA Rule 5110(g)(8)(B) and (C), the Holder shall not be entitled to more than one demand registration right hereunder and the duration of the registration rights hereunder shall not exceed five years from the Initial Exercise Date.

3. Transfer.

3.1 General Restrictions. The registered Holder of this Purchase Warrant agrees by such Xxxxxx’s acceptance hereof, that such Holder will not: (a) sell, transfer, assign, pledge or hypothecate this Purchase Warrant for a period of one hundred eighty (180) days following the Initial Exercise Date to anyone other than to, (i) the Holder or an underwriter, placement agent, or a selected dealer participating in the Offering, or (ii) a bona fide officer or partner of the Holder or of any such underwriter, placement agent or selected dealer, in each case in accordance with FINRA Conduct Rule 5110(e)(1), or (b) for a period of one hundred eighty (180) days following the Initial Exercise Date cause this Purchase Warrant or the securities issuable hereunder to be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of this Purchase Warrant or the securities hereunder, except as provided for in FINRA Rule 5110(e)(2). After 180 days after the Initial Exercise Date, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Warrant and payment of all transfer taxes, if any, payable in connection therewith. The Company shall within five (5) Business Days transfer this Purchase Warrant on the books of the Company and shall execute and deliver a new Purchase Warrant or Purchase Warrants of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of Shares purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.

3.2 Restrictions Imposed by the Securities Act. The securities evidenced by this Purchase Warrant shall not be transferred unless and until: (i) if required by applicable law, the Company has received the opinion of counsel for the Company that the securities may be transferred pursuant to an exemption from registration under the Securities Act and applicable state securities laws, or (ii) a registration statement or a post-effective amendment to the Registration Statement relating to the offer and sale of such securities has been filed by the Company and declared effective by the Commission and compliance with applicable state securities law has been established.

4. Piggyback Registration Rights.

4.1 Grant of Right. In the event that there is not an effective registration statement covering the Purchase Warrant or the underlying Shares, whenever the Company proposes to register any shares of its Common Stock under the Securities Act (other than (i) a registration statement to register shares under an employee benefit plan or to effect a transaction to which Rule 145 of the Securities Act is applicable, or (ii) a registration statement on Form S-4, S-8 or any successor form thereto or another form not available for registering the Shares issuable upon exercise of this Purchase Warrant for sale to the public, whether for its own account or for the account of one or more stockholders of the Company (a “Piggyback Registration”)), the Company shall give prompt written notice (in any event no later than ten (10) Business Days prior to the filing of such registration statement) to the Holder of the Company’s intention to effect such a registration and, subject to the remaining provisions of this Section 4.1, shall include in such registration such number of Shares underlying this Purchase Warrant (the “Registrable Securities”) that the Holder has (within ten (10) Business Days of the respective Holder’s receipt of such notice) requested in writing (including such number) to be included within such registration. If, in connection with an underwritten offering, the managing underwriter advises the Company that it has determined in good faith that marketing factors require a limit on the number of shares of Common Stock to be included in such registration, the Company shall include in such registration (i) first, the number of shares of Common Stock that the Company proposes to issue and sell pursuant to such underwritten offering and (ii) second, the number of shares of Common Stock, if any, requested to be included therein by selling stockholders (including the Holder) allocated pro rata among all such persons on the basis of the number of shares of Common Stock then owned by each such person as compared to the total number of shares the managing underwriter shall permit to be included in such registration. In connection with any Piggyback Registration, Holder shall pay any and all underwriting commissions (if the offering is an underwritten offering) and the expenses of any legal counsel selected by Holder to represent it in connection with the sale of the Registrable Securities. Notwithstanding anything to the contrary, the obligations of the Company pursuant to this Section 4.1 shall terminate on the earlier of (i) the fifth anniversary of the Initial Exercise Date and (ii) the date that Rule 144 would allow the Holder to sell its Registrable Securities during any ninety (90) day period. The duration of the piggyback registration right shall not exceed seven years from the Initial Exercise Date, in accordance with FINRA Rule 5110(g)(8)(D)).

4

4.2 Indemnification. The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Securities Act or Section 20 (a) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other out-of-pocket expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become subject under the Securities Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify Holder contained in the Underwriting Agreement between Brookline and the Company, dated as of [●], 2024. The Holder(s) of the Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally, and not jointly, indemnify the Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Securities Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions contained in the Underwriting Agreement pursuant to which Brookline has agreed to indemnify the Company.

4.3 Exercise of Purchase Warrants. Nothing contained in this Purchase Warrant shall be construed as requiring the Holder(s) to exercise their Purchase Warrants prior to or after the initial filing of any registration statement or the effectiveness thereof.

4.4 Documents Delivered to Holders. The Company shall deliver promptly to each Holder participating in the offering requesting the correspondence and memoranda described below, copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times, during normal business hours, as any such Holder shall reasonably request.

4.5 Underwriting Agreement. The Holders shall be parties to any underwriting agreement relating to a Piggyback Registration. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders, their Shares and the amount and nature of their ownership thereof and their intended methods of distribution.

4.6 Documents to be Delivered by Xxxxxx(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders.

4.7 Damages. Should the Company fail to comply with the applicable provisions in this Section 4, the Holder shall, in addition to any other legal or other relief available to the Holder, be entitled to obtain specific performance or other equitable (including injunctive) relief against the threatened breach of such provisions or the continuation of any such breach, without the necessity of proving actual damages and without the necessity of posting bond or other security.

5. New Purchase Warrants to be Issued.

5.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Warrant for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax if exercised pursuant to Section 2.1 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor to this Purchase Warrant in the name of the Holder evidencing the right of the Holder to purchase the number of Shares purchasable hereunder as to which this Purchase Warrant has not been exercised or assigned.

5.2 Lost Warrant. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Purchase Warrant and of reasonably satisfactory indemnification or the posting of a bond, determined in the sole discretion of the Company, the Company shall execute and deliver a new Purchase Warrant of like tenor and date. Any such new Purchase Warrant executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.

6. Adjustments.

6.1 Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of Shares underlying the Purchase Warrant shall be subject to adjustment from time to time as hereinafter set forth:

6.1.1 Share Dividends; Split Ups. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding Shares is increased by a stock dividend payable in Shares or by a split up of Shares or other similar event, then, on the effective day thereof, the number of Shares purchasable hereunder shall be increased in proportion to such increase in outstanding Shares, and the Exercise Price shall be proportionately decreased.

6.1.2 Aggregation of Shares. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding Shares is decreased by a consolidation, combination or reclassification of Shares or other similar event, then, on the Initial Exercise Date thereof, the number of Shares purchasable hereunder shall be decreased in proportion to such decrease in outstanding Shares, and the Exercise Price shall be proportionately increased.

6.1.3 Replacement of Securities upon Reorganization, Etc. In case of any reclassification or reorganization of the outstanding Shares other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Shares, or in the case of any share reconstruction or amalgamation or consolidation or merger of the Company with or into another corporation (other than a consolidation or share reconstruction or amalgamation or merger in which the Company is the continuing company and that does not result in any reclassification or reorganization of the outstanding Shares), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have the right thereafter (until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of Shares of the Company obtainable upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also results in a change in Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers.

6

6.1.4 Changes in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section 6.1, and Purchase Warrants issued after such change may state the same Exercise Price and the same number of Shares as are stated in the Purchase Warrants initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Warrants reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

6.2 Substitute Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation or merger of the Company with or into, another corporation (other than a consolidation or share reconstruction or amalgamation or merger which does not result in any reclassification or change of the outstanding Shares), the corporation formed by such consolidation or share reconstruction or amalgamation shall execute and deliver to the Holder a supplemental Purchase Warrant providing that the holder of each Purchase Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Warrant) to receive, upon exercise of such Purchase Warrant, the kind and amount of shares and other securities and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of Shares of the Company for which such Purchase Warrant might have been exercised immediately prior to such consolidation, share reconstruction or amalgamation or merger, sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which shall be identical to the adjustments provided for in this Section 6. The above provision of this Section shall similarly apply to successive consolidations or share reconstructions or amalgamations or mergers.

6.3 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares upon the exercise of the Purchase Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the case may be, to the nearest whole number of Shares or other securities, properties or rights.

7. Reservation. The Company shall at all times reserve and keep available out of its authorized Shares, solely for the purpose of issuance upon exercise of the Purchase Warrants, such number of Shares or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Warrants and payment of the Exercise Price therefor, in accordance with the terms hereby, all Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder.

8. Certain Notice Requirements.

8.1 Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holder the right to vote or consent or to receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder of the Company. If, however, at any time prior to the expiration of the Purchase Warrants and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall deliver to each Holder a copy of each notice relating to such events given to the other shareholders of the Company at the same time and in the same manner that such notice is given to the shareholders.

8.2 Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its Shares for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company shall offer to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor.

7

8.3 Notice of Change in Exercise Price. The Company shall, within three (3) Business Days after an event requiring a change in the Exercise Price pursuant to Section 6 hereof, send notice to the Holder of such event and change (“Price Notice”). The Price Notice shall describe the event causing the change and the method of calculating same.

8.4 Transmittal of Notices. All notices, requests, consents and other communications under this Purchase Warrant shall be in writing and delivered personally, by e-mail, or sent by a nationally recognized overnight courier service to following addresses or to such other address as the Holder or the Company may designate by notice to the other party and shall be deemed given and effective on the earliest of (i) the time of transmission, if such notice or communication is delivered via e-mail (with confirmation of receipt from the intended recipient by return e-mail or other written acknowledgment) at the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Business Day after the time of transmission, if such notice or communication is delivered via e-mail (with confirmation of receipt from the intended recipient by return email or other written acknowledgment) at the e-mail address set forth in this Section on a day that is not a Business Day or later than 5:30 p.m. (New York City time) on any Business Day, (iii) the second Business Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given:
