Dear Mr. Nielsen,

This letter (the “Agreement”) constitutes the agreement between Maxim Group, LLC (“Maxim” or the “Placement Agent”) and Bio-Path Holdings, Inc. (the “Company”), that Maxim shall serve as the exclusive placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of registered securities (the “Securities”) of the Company, including shares (the “Shares”) of the Company’s common stock (the “Common Stock”)[and warrants to purchase shares of Common Stock]. The terms of such Placement and the Securities shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that Maxim would have the power or authority to bind the Company or any Purchaser or an obligation for the Company to issue any Securities or complete the Placement. This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the Placement shall be collectively referred to herein as the “Transaction Documents.” The date of the closing of the Placement shall be referred to herein as the “Closing Date.” The Company expressly acknowledges and agrees that Maxim’s obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by Maxim to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of Maxim with respect to securing any other financing on behalf of the Company.

SECTION 1.        Compensation and other Fees.

As compensation for the services provided by Maxim hereunder, the Company agrees to pay to Maxim:

(B)      The Company also agrees to reimburse Maxim’s actual expenses reasonably incurred in connection with the Placement, provided Maxim provides to the Company with supporting documentation therefore. The Company will reimburse Maxim in a timely manner for all such expenses, including, but not limited to, printing, road show, travel and other related expenses as well as the reasonable legal fees incurred by Maxim in connection with the Placement; provided, however, that (a) any single item in excess of $2,000 (other than legal fees and expenses) and (b) all expenses in excess of $5,000 in any one month (other than legal fees and expenses), shall require the Company’s prior written approval (including via “electronic mail”). Notwithstanding anything contained herein to the contrary, in no event shall the Company be obligated to reimburse Maxim for its outside legal fees to the extent they exceed $75,000 in the aggregate, without prior written approval (including via “electronic mail”) by the Company and such approval shall not be unreasonably withheld; provided, however, that in the event the Placement is not consummated, the Company shall not be obligated to reimburse Maxim for such legal fees to the extent they exceed $10,000.

Maxim reserves the right to reduce any item of its compensation or adjust the terms thereof as specified herein in the event that a determination and/or suggestion shall be made by FINRA to the effect that the Placement Agent’s aggregate compensation is in excess of FINRA rules or that the terms thereof require adjustment; provided, however, the aggregate compensation otherwise to be paid to the underwriters by the Company may not be increased above the amounts stated herein without the approval of the Company.

Upon the Registration Statement (as defined below) being declared effective, the Company, at such time, represents and warrants to, and agrees with, the Placement Agent that:

(A)             The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), for the registration under the Securities Act of the Securities.At the time of such filing, the Company met the requirements of Form S-3 under the Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a supplement to the form of prospectus included in such registration statement relating to the placement of the Securities and the plan of distribution thereof and has advised, or will advise prior to the filing of such supplement, the Placement Agent of all further information (financial and other) with respect to the Company required to be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement”; such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company's knowledge, is threatened by the Commission. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and the “Time of Sale Prospectus” means the preliminary prospectus, if any, together with the free writing prospectuses, if any, used in connection with the Placement, including any documents incorporated by reference therein.
