NeuroOne Medical Technologies Corporation

[Form of] Common Stock Purchase Warrant

_________________

This Certifies That, for value received, [NAME], or his/her/our registered assigns (the “Purchaser”), is entitled to subscribe for and purchase from NeuroOne Medical Technologies Corporation, a Delaware corporation (the “Company”), at any time commencing on [DATE] and expiring on [five year anniversary date] (such period, the “Warrant Exercise Term”), the Shares at the Exercise Price (each as defined in Section 1 below).

This Warrant is issued in connection with the Company’s private placement solely to accredited investors of units, each consisting of 1 share of the Company’s common stock, par value $0.001 per share (the “Common Stock”), and a warrant to purchase 1 share of Common Stock, (the “Private Placement”), which may be issued in one or more closings, in accordance with, and subject to, the terms and conditions described in the Subscription Agreement, dated as of even date herewith (the “Subscription Agreement”). Capitalized terms used and not otherwise defined herein shall have the respective meanings assigned to such terms in the Subscription Agreement.

This Warrant is subject to the following terms and conditions:

1. Shares. The Purchaser has, subject to the terms set forth herein, the right to purchase, at any time during the Warrant Exercise Term, up to [NUMBER OF SHARES] shares of Common Stock, at a per share exercise price of $3.00 (as the same may be adjusted as provided in Section 3 hereof, the “Exercise Price”). The shares of Common Stock received upon any exercise of this Warrant are referred to herein as the “Shares”.

2. Exercise of Warrant.

(a) Exercise. This Warrant may be exercised by the Purchaser at any time during the Warrant Exercise Term, in whole or in part, by delivering to the Company at its principal office, or at such other office as the Company may designate (i) the notice of exercise attached as Exhibit A hereto (the “Notice of Exercise”), duly executed by the Purchaser and (ii) this Warrant certificate, accompanied by (iii) payment, in cash or by wire transfer of immediately available funds or by check payable to the order of the Company of the amount obtained by multiplying the number of Shares designated in the Notice of Exercise by the Exercise Price (the “Purchase Price”). For purposes hereof, “Exercise Date” shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant to this Section 2(a) shall have been made. In no event shall the Company be required to net cash settle any Warrant exercise.

(b) Redemption.

(i) All of the outstanding Warrants (but not less than all) may be redeemed, at the option of the Company, at any time beginning after the one-year anniversary of the date hereof and during the Warrant Exercise Term upon notice to the Purchaser at the price of $3.00 per Warrant (the “Redemption Price”), provided that the VWAP (as defined below) of the Common Stock is at least 200% of the Exercise Price for 20 consecutive Trading Days prior to the date on which notice of the redemption is given. “VWAP” means, for any date, the price determined by the first of the following clauses that applies: (A) if the Common Stock is then listed or quoted on a Trading Market (other than the OTC Bulletin Board or OTC Markets, Inc.), the daily volume weighted average price of the Common Stock for such date (or the nearest preceding Trading Day) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (B) if the Common Stock is then quoted on the OTC Bulletin Board, the volume weighted average price of the Common Stock for such date (or the nearest preceding Trading Day) on the OTC Bulletin Board, (C) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported on OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (D) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company. “Trading Day” means a day on which the principal Trading Market is open for trading. “Trading Market” means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE MKT, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange (or any successors to any of the foregoing), the OTC Bulletin Board or OTC Markets, Inc.

(ii) The Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the Redemption Date to the Purchasers to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Purchaser received such notice.

(iii) The notice of redemption shall contain the information necessary to calculate the number of Shares to be received upon exercise of the Warrants, including the VWAP calculations. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

(c) Issuance of Certificates. As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof, the Company, at its expense, shall cause to be issued in the name of and delivered to the Purchaser (i) a certificate or certificates for the number of validly issued, fully paid and non-assessable Shares to which the Purchaser shall be entitled upon such exercise and, if applicable and (ii) a new warrant of like tenor to purchase all of the Shares that may be purchased pursuant to the portion, if any, of this Warrant not exercised by the Purchaser. The Purchaser shall for all purposes hereof be deemed to have become the Purchaser of record of such Shares on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2(a) hereof were delivered and made, respectively, irrespective of the date of delivery of such certificate or certificates, except that if the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which the stock transfer books are open. Shares purchased hereunder shall be transmitted by the transfer agent to the Purchaser by crediting the account of the Purchaser’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Shares to or resale of the Shares by the Purchaser or (B) the Shares are eligible for resale by the Purchaser without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the Purchaser in the Notice of Exercise by the date that is three Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise and (B) surrender of this Warrant (if required).

3. Adjustment of Exercise Price and Number of Shares.

(a) Adjustment for Reclassification, Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired there shall be (i) a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation or other entity in which the Company shall not be the surviving entity, or a reverse merger in which the Company shall be the surviving entity but the shares of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and assets as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series of related transactions, then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless otherwise directed by the Purchaser, all necessary or appropriate lawful provisions shall be made so that the Purchaser shall thereafter be entitled to receive upon exercise of this Warrant during the Warrant Exercise Term and upon payment of the Exercise Price then in effect, the greatest number of shares of capital stock or other securities or property that a holder of the Shares deliverable upon exercise of this Warrant would have been entitled to receive in such reorganization, recapitalization, merger, consolidation, sale or transfer if this Warrant had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation, sale or transfer, all subject to further adjustment as provided in this Section 3. If the per share consideration payable to the Purchaser for Shares in connection with any such transaction is in a form other than cash or marketable securities, then the value of such consideration shall be determined in good faith by the Board. The foregoing provisions of this paragraph shall similarly apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers and to the capital stock or securities of any other corporation that are at the time receivable upon the exercise of this Warrant. In all events, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Purchaser after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably may be, in relation to any shares or other property deliverable or issuable after such reorganization, recapitalization, merger, consolidation, sale or transfer upon exercise of this Warrant.

(b) Adjustments for Split, Subdivision or Combination of Shares. If the Company shall at any time subdivide (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition hereunder, then, after the date of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant will be proportionately increased. If the Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition hereunder, then, after the record date for effecting such combination, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant will be proportionately decreased.

(c) Adjustments for Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired, the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or, on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend, then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of such other or additional stock or other securities or property (other than cash) of the Company that such holder would be entitled to receive had it been the holder of record of the class of security receivable upon exercise of this Warrant on the record date fixed for the determination of stockholders eligible to receive such dividend, giving effect to all adjustments called for by the provisions of this Section 3 that occur from such record date to the date of such exercise.

(d) [Reserved.]

(e) Notice of Adjustments. Upon any adjustment of the Exercise Price and any increase or decrease in the number of Shares purchasable upon the exercise of this Warrant, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Purchaser at the address of such Purchaser as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and, if applicable, the increased or decreased number of Shares purchasable upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation of each. The Purchaser and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this Section 3, following any adjustment hereunder, the number of Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

4. Transfer of Warrant.

(a) Transfer Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Purchaser or transferee of this Warrant, as the case may be, comply with the transfer restrictions of the Subscription Agreement.

(b) Purchaser Representation. The Purchaser, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

5.  Notices. All notices, requests, consents and other communications required or permitted under this Warrant shall be in writing and shall be deemed delivered (i) three business days after being sent by registered or certified mail, return receipt requested, postage prepaid or (ii) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business day delivery or (iii) on the business day of delivery if sent by facsimile or electronic transmission, in each case to the intended recipient as set forth below:

8. Fractional Shares. No fractional Shares will be issued in connection with any exercise hereunder. Instead, the Company shall round the number of Shares to be issued up to the nearest whole Share. This Warrant may only be exercised for whole shares.

10. Miscellaneous.

(a) All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Subscription Agreement. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.
