Exhibit 10.4

WARRANT AMENDMENT AGREEMENT

This Warrant Amendment Agreement (this “Agreement”), dated as of September __, 2020, is by and between Neurotrope, Inc., a Nevada corporation (the “Company”), and the undersigned holder (the “Holder”) of Series G warrants to purchase shares of the Company’s common stock, $0.0001 par value (the “Common Stock”).

WHEREAS, the Holder beneficially owns Series G warrants to purchase shares of Common Stock at an exercise price of $4.37 per share that were issued in December 2018, as set forth on the Holder's signature page hereto (the “Original Warrants”).

WHEREAS, the Company and the Holders desire to amend and restate the Original Warrants to (a) reduce the exercise price thereof from $4.37 to $3.50 per share, (b) extend the Termination Date of the Original Warrants from December 2023 to either (i) the five year anniversary of the closing of the mergers contemplated by the Merger Agreement (as defined below), or (ii) if the Merger Agreement is terminated or the mergers contemplated thereby have not been consummated, June 17, 2025, and (c) revise the Original Warrants to provide that in the event of a spin-off (the “Spin-Off”) of Neurotrope Bioscience, Inc. or any other entity or entities containing the existing business of the Company (collectively, the “Spin-Off Company”), the Holder shall only receive, in lieu of any other consideration, warrants, in the form attached hereto as Exhibit A (the "Spin-Off Warrants"), to purchase a number of shares of Spin-Off Company based on the same ratio as the ratio used to determine the number of shares of common stock of Spin-Off Company that common stockholders of the Company will receive in the Spin-Off, as more fully described in the following WHEREAS clause. The initial exercise price of the Spin-Off Warrants will be determined by dividing $50 million by the number of shares of common stock of Spin-Off Company outstanding immediately after the Spin-Off, excluding any shares issued in connection with a financing of Spin-off Company after the date hereof. As used herein "Merger Agreement" means that certain Agreement and Plan of Merger and Reorganization dated as of May 17, 2020 among the Company, Petros Pharmaceuticals, Inc., PM Merger Sub 1, LLC, PN Merger Sub 2, Inc. and Metuchen Pharmaceuticals LLC (the "Original Merger Agreement"), as such Original Merger Agreement may be (i) amended from time to time or have any provision thereof waived from time to time, in each case that results in the stockholders of the Company owning 49% or more of the outstanding common stock of the combined company at the closing of the mergers contemplated by such Merger Agreement and is not, and is not reasonably expected to be, otherwise detrimental to the Holder, or (ii) in the event of an amendment or waiver that does not meet the standards of (i) above, is amended from time to time or have any provision thereof waived from time to time, in each case with the prior written consent of holders of a majority of the Series G Warrants who have signed this Agreement or agreements substantially similar to this Agreement.

WHEREAS, the number of shares of common stock underlying the Spin-Off Warrants shall be determined by using the same ratio used to determine how many shares of Spin-Off Company that the common stockholders of the Company will receive in the Spin-Off, it being contemplated as of the date of this Agreement that the Spin-Off will result in each common stockholder of the Company receiving one share of the Spin-Off Company for every five shares of the Company owned by such stockholder (the “Spin-Off Ratio”). Although the Spin-Off Ratio may change depending on a number of factors, the number of shares of common stock of the Spin-Off Company underlying the Spin-Off Warrants will be based on the final Spin-Off Ratio. In other words, assuming that the final Spin-Off Ratio is the same as the currently contemplated Spin-Off Ratio, the Spin-Off Warrants will be exercisable for one share of Spin-Off Company for every five shares of Company Common Stock underlying your Original Warrants. If the Spin-Off Ratio changes after the date of this Agreement, so will the ratio applicable to the Spin-Off Warrants.

WHEREAS, pursuant to Section 5(l) of the Original Warrants, the Original Warrants may be modified or amended or the provisions thereof waived with the written consent of the Company and the Holder.

3. Spin-Off Warrants. The Company agrees to cause the Spin-Off Company to issue to the Holder upon consummation of the Spin-Off, the Spin-Off Warrants exercisable for the number of shares and at the exercise price determined as provided in the preceding WHEREAS clauses.
