Exhibit 1.1

June 24, 2016

STRICTLY CONFIDENTIAL

Bio-Path Holdings, Inc.

4710 Bellaire Boulevard

Suite 210

Bellaire, TX 77401

Attn: Mr. Peter H. Nielsen

Dear Mr. Nielsen:

This letter agreement (this “Agreement”) constitutes the agreement between Bio-Path Holdings, Inc. (the “Company”) and H.C. Wainwright & Co., LLC (“HCW”), that HCW shall serve as the exclusive agent, advisor or underwriter in the offering (the “Offering”) of securities of the Company (“Securities”) during the Term (as defined below) of this Agreement. The terms of the Offering and the Securities issued in connection therewith shall be mutually agreed upon by the Company and HCW and nothing herein implies that HCW would have the power or authority to bind the Company and nothing herein implies that the Company shall have an obligation to issue any Securities. It is understood that HCW’s assistance in the Offering will be subject to the satisfactory completion of such investigation and inquiry into the affairs of the Company as HCW deems appropriate under the circumstances and to the receipt of all internal approvals of HCW in connection with the transaction. The Company expressly acknowledges and agrees that HCW involvement in the Offering is strictly on a reasonable best efforts basis and that the consummation of the Offering will be subject to, among other things, market conditions. The execution of this Agreement does not constitute a commitment by HCW to purchase the Securities and does not ensure a successful Offering of the Securities or the success of HCW with respect to securing any other financing on behalf of the Company. HCW may retain other brokers, dealers, agents or underwriters, subject to the approval of the Company, on its behalf in connection with the Offering, and HCW shall be solely responsible for the payment of any compensation or expenses to such other broker, dealer, agent or underwriter.

A.                 Compensation; Reimbursement. At the closing of the Offering (the “Closing”), the Company shall compensate HCW as follows:

1.                  Cash Fee. The Company shall pay to HCW a cash fee, or as to an underwritten Offering an underwriter discount, equal to 6% of the aggregate gross proceeds raised in the Offering.

2.                  Warrant Coverage. The Company shall issue to HCW or its designees at the Closing, warrants (the “HCW Warrants”) to purchase 250,000 shares of common stock of the Company, provided gross proceeds from the Offering are at least $10 million. If the Securities included in the Offering are non-convertible, the HCW Warrants shall be determined by dividing the gross proceeds raised in such Offering divided by the then market price of the Common Stock. The HCW Warrants shall have the same terms as the warrants issued to investors in the Offering, if applicable. If no warrants are issued to investors in the Offering, the HCW Warrants shall be in a customary form reasonably acceptable to HCW and the Company, have a term of 5 years and an exercise price equal to 125% of the then market price of the Common Stock.

3.                  Expense Allowance. Out of the proceeds of the Closing, the Company also agrees to pay HCW a non accountable expense allowance of $25,000 (provided, however, that such reimbursement amount in no way limits or impairs the indemnification and contribution provisions of this Agreement). The cost of legal fees, closing fees and diligence fees of up to an aggregate amount of $75,000 will be deducted from HCW’s cash fee at the Closing; provided, however, that in the event the Offering is withdrawn by the Company, the Company shall pay the reasonable costs incurred for legal fees, closing fees and diligence fees, up to an aggregate amount of $75,000, inclusive of the $25,000 expense allowance contemplated in the immediately preceding sentence.

B.                 Term and Termination of Engagement; Exclusivity. The term of HCW’s exclusive engagement will begin on the date hereof and end 30 days after the date hereof (the “Term”). Notwithstanding anything to the contrary contained herein, the Company agrees that the provisions relating to the payment of fees, reimbursement of expenses, indemnification and contribution, confidentiality, conflicts, independent contractor and waiver of the right to trial by jury will survive any termination of this Agreement. During HCW’s engagement hereunder: (i) the Company will not, and will not permit its representatives to, other than in coordination with HCW, contact or solicit institutions, corporations or other entities or individuals as potential purchasers of the Securities and (ii) the Company will not pursue any financing transaction which would be in lieu of the Offering. Furthermore, the Company agrees that during HCW’s engagement hereunder, all inquiries, whether direct or indirect, from prospective investors will be referred to HCW and will be deemed to have been contacted by HCW in connection with the Offering.

C.                 Information; Reliance. The Company shall furnish, or cause to be furnished, to HCW all information reasonably requested by HCW for the purpose of rendering services hereunder (all such information being the “Information”). In addition, the Company agrees to make available to HCW upon request from time to time the officers, directors, accountants, counsel and other advisors of the Company. The Company recognizes and confirms that HCW (a) will use and rely on the Information, including any documents provided to investors in the Offering (the “Offering Documents” which shall include any Purchase Agreements (as defined below)), and on information available from generally recognized public sources in performing the services contemplated by this Agreement without having independently verified the same; (b) does not assume responsibility for the accuracy or completeness of the Offering Documents or the Information and such other information; and (c) will not make an appraisal of any of the assets or liabilities of the Company. Upon reasonable request, the Company will meet with HCW or its representatives to discuss all information relevant for disclosure in the Offering Documents and will cooperate in any investigation undertaken by HCW thereof, including any document included or incorporated by reference therein. At the Offering, at the request of HCW, the Company shall deliver such legal letters, comfort letters and officer’s certificates, all in form and substance reasonably satisfactory to HCW and its counsel as is customary for such Offering. HCW shall be a third party beneficiary of any representations, warranties, covenants and closing conditions made by the Company in any Offering Documents, including representations, warranties, covenants and closing conditions made to any investor in the Offering.

D.                 Related Agreements. At the Offering, the Company shall enter into the following additional agreements, as applicable:

1.                  Underwritten Offering. If the Offering is an underwritten Offering, the Company and HCW shall enter into a customary underwriting agreement in form and substance mutually satisfactory to HCW and the Company and their respective counsel.

2.                  Best Efforts Offering. If the Offering is on a best efforts basis, the sale of Securities to the investors in the Offering will be evidenced by a purchase agreement (“Purchase Agreement”) between the Company and such investors in a form reasonably satisfactory to the Company and HCW. Prior to the signing of any Purchase Agreement, officers of the Company with responsibility for financial affairs will be available to answer inquiries from prospective investors.

3.                  Escrow and Settlement. In respect of the Offering, the Company and HCW shall enter into an escrow agreement with a third party escrow agent, which may also be HCW’s clearing agent, pursuant to which HCW’s compensation and expenses shall be paid from the gross proceeds of the Securities sold. If the Offering is settled in whole or in part via delivery versus payment (“DVP”), HCW shall arrange for its clearing agent to provide the funds to facilitate such settlement. The Company shall bear the cost of the escrow agent and shall reimburse HCW for the actual out of pocket cost of such clearing agent settlement and financing, if any, up to $10,000.

4.                  FINRA Amendments. Notwithstanding anything herein to the contrary, in the event that HCW or FINRA determines that any of the terms provided for hereunder shall not comply with a FINRA rule, including but not limited to FINRA Rule 5110, then the Company shall agree to amend this Agreement (or include such revisions in the final underwriting) in writing upon the request of HCW to comply with any such rules; provided that any such amendments shall not provide for terms that are less favorable to the Company.

E.                  Confidentiality. In the event of the consummation or public announcement of the Offering, HCW shall have the right to disclose its participation in such Offering, including, without limitation, the Offering at its cost of “tombstone” advertisements in financial and other newspapers and journals.

F.                  Indemnity.

1.                  In connection with the Company’s engagement of HCW as Offering agent, the Company hereby agrees to indemnify and hold harmless HCW and its affiliates, and the respective controlling persons, directors, officers, members, shareholders, agents and employees of any of the foregoing (collectively the “Indemnified Persons”), from and against any and all claims, actions, suits, proceedings (including those of shareholders), damages, liabilities and expenses incurred by any of them (including the reasonable fees and expenses of counsel), as incurred, (collectively a “Claim”), that are (A) related to or arise out of (i) any actions taken or omitted to be taken (including any untrue statements made or any statements omitted to be made) by the Company, or (ii) any actions taken or omitted to be taken by any Indemnified Person in connection with the Company’s engagement of HCW, or (B) otherwise relate to or arise out of HCW’s activities on the Company’s behalf under HCW’s engagement, and the Company shall reimburse any Indemnified Person for all expenses (including the reasonable fees and expenses of counsel) as incurred by such Indemnified Person in connection with investigating, preparing or defending any such claim, action, suit or proceeding, whether or not in connection with pending or threatened litigation in which any Indemnified Person is a party. The Company will not, however, be responsible for any Claim that is judicially determined to have resulted from the gross negligence or willful misconduct of any person seeking indemnification for such Claim, or arises from any information contained in the Offering Documents that was furnished to the Company by HCW in writing expressly for inclusion in the Offering Documents. The Company further agrees that no Indemnified Person shall have any liability to the Company for or in connection with the Company’s engagement of HCW except for any Claim incurred by the Company as a result of such Indemnified Person’s gross negligence or willful misconduct.

2.                  The Company further agrees that it will not, without the prior written consent of HCW, settle, compromise or consent to the entry of any judgment in any pending or threatened Claim in respect of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party to such Claim), unless such settlement, compromise or consent includes an unconditional, irrevocable release of each Indemnified Person from any and all liability arising out of such Claim.

3.                  Promptly upon receipt by an Indemnified Person of notice of any complaint or the assertion or institution of any Claim with respect to which indemnification is being sought hereunder, such Indemnified Person shall notify the Company in writing of such complaint or of such assertion or institution but failure 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 materially prejudices the Company. If the Company so elects or is requested by such Indemnified Person, the Company will assume the defense of such Claim, including the employment of counsel reasonably satisfactory to such Indemnified Person and the payment of the fees and expenses of such counsel. In the event, however, that legal counsel to such Indemnified Person reasonably determines that having common counsel would present such counsel with a conflict of interest or if the defendant in, or target of, any such Claim, includes an Indemnified Person and the Company, and legal counsel to such Indemnified Person reasonably concludes that there may be legal defenses available to it or other Indemnified Persons different from or in addition to those available to the Company, then such Indemnified Person may employ its own separate counsel to represent or defend him, her or it in any such Claim and the Company shall pay the reasonable fees and expenses of such counsel. Notwithstanding anything herein to the contrary, if the Company fails timely or diligently to defend, contest, or otherwise protect against any Claim, the relevant Indemnified Party shall have the right, but not the obligation, to defend, contest, compromise, settle, assert crossclaims, or counterclaims or otherwise protect against the same, and shall be fully indemnified by the Company therefor, including without limitation, for the reasonable fees and expenses of its counsel and all amounts paid as a result of such Claim or the compromise or settlement thereof. In addition, with respect to any Claim in which the Company assumes the defense, the Indemnified Person shall have the right to participate in such Claim and to retain his, her or its own counsel therefor at his, her or its own expense.

4.                  The Company agrees that if any indemnity sought by an Indemnified Person hereunder is held by a court to be unavailable for any reason then (whether or not HCW is the Indemnified Person), the Company and HCW shall contribute to the Claim for which such indemnity is held unavailable in such proportion as is appropriate to reflect the relative benefits to the Company, on the one hand, and HCW on the other, in connection with HCW’s engagement referred to above, subject to the limitation that in no event shall the amount of HCW’s contribution to such Claim exceed the amount of fees actually received by HCW from the Company pursuant to HCW’s engagement. The Company hereby agrees that the relative benefits to the Company, on the one hand, and HCW on the other, with respect to HCW’s engagement shall be deemed to be in the same proportion as (a) the total value paid or proposed to be paid or received by the Company pursuant to the Offering (whether or not consummated) for which HCW is engaged to render services bears to (b) the fee paid or proposed to be paid to HCW in connection with such engagement.

5.                  The Company’s indemnity, reimbursement and contribution obligations under this Agreement (a) shall be in addition to, and shall in no way limit or otherwise adversely affect any rights that any Indemnified Party may have at law or at equity and (b) shall be effective whether or not the Company is at fault in any way.

G.                 Limitation of Engagement to the Company. The Company acknowledges that HCW has been retained only by the Company, that HCW is providing services hereunder as an independent contractor (and not in any fiduciary or agency capacity) and that the Company’s engagement of HCW is not deemed to be on behalf of, and is not intended to confer rights upon, any shareholder, owner or partner of the Company or any other person not a party hereto as against HCW or any of its affiliates, or any of its or their respective officers, directors, controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), employees or agents. Unless otherwise expressly agreed in writing by HCW, no one other than the Company is authorized to rely upon this Agreement or any other statements or conduct of HCW, and no one other than the Company is intended to be a beneficiary of this Agreement. The Company acknowledges that any recommendation or advice, written or oral, given by HCW to the Company in connection with HCW’s engagement is intended solely for the benefit and use of the Company’s management and directors in considering a possible Offering, and any such recommendation or advice is not on behalf of, and shall not confer any rights or remedies upon, any other person or be used or relied upon for any other purpose. HCW shall not have the authority to make any commitment binding on the Company. The Company, in its sole discretion, shall have the right to reject any investor introduced to it by HCW.

H.                 Limitation of HCW’s Liability to the Company. HCW and the Company further agree that neither HCW nor any of its affiliates or any of its their respective officers, directors, controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), employees or agents shall have any liability to the Company, its security holders or creditors, or any person asserting claims on behalf of or in the right of the Company (whether direct or indirect, in contract, tort, for an act of negligence or otherwise) for any losses, fees, damages, liabilities, costs, expenses or equitable relief arising out of or relating to this Agreement or the services rendered hereunder, except for losses, fees, damages, liabilities, costs or expenses that arise out of or are based on any action of or failure to act by HCW and that are judicially determined to have resulted from the gross negligence or willful misconduct of HCW.

I.                    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be fully performed therein. Any disputes that arise under this Agreement, even after the termination of this Agreement, will be heard only in the state or federal courts located in the City of New York, State of New York. The parties hereto expressly agree to submit themselves to the jurisdiction of the foregoing courts in the City of New York, State of New York. The parties hereto expressly waive any rights they may have to contest the jurisdiction, venue or authority of any court sitting in the City and State of New York. In the event HCW or any Indemnified Person is successful in any action, or suit against the Company, arising out of or relating to this Agreement, the final judgment or award entered shall be entitled to have and recover from the Company the costs and expenses incurred in connection therewith, including its reasonable attorneys’ fees. Any rights to trial by jury with respect to any such action, proceeding or suit are hereby waived by HCW and the Company.

K.                 Conflicts. The Company acknowledges that HCW and its affiliates may have and may continue to have investment banking and other relationships with parties other than the Company pursuant to which HCW may acquire information of interest to the Company. HCW shall have no obligation to disclose such information to the Company or to use such information in connection with any contemplated transaction.

L.                  Anti-Money Laundering. To help the United States government fight the funding of terrorism and money laundering, the federal laws of the United States requires all financial institutions to obtain, verify and record information that identifies each person with whom they do business.

This Agreement shall be binding upon and inure to the benefit of both HCW and the Company and their respective assigns, successors, and legal representatives.
