 Exhibit 4.1 

[FORM OF WARRANT AGREEMENT] 

WARRANT AGREEMENT 
 This
Warrant Agreement (“Warrant Agreement”) is entered into as of July 27, 2016, by and between ContraFect Corporation, a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC
(the “Warrant Agent”). 
 WHEREAS, the Company is engaged in a public offering (the “Public Offering”) of
shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”), and warrants (each a “Warrant” or, collectively, the “Warrants”) entitling holders to purchase shares of
Common Stock (the “Warrant Shares”); 
 WHEREAS, the shares of Common Stock and the Warrants will be sold in
combination, with one warrant to purchase one (1) share of Common Stock accompanying each share of Common Stock sold. The shares of Common Stock and the Warrants are immediately separable and will be issued separately; 

WHEREAS, the Company has filed, with the Securities and Exchange Commission, a registration statement on Form S-3 (Registration
No. 333-211748), as amended (the “Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the “Act”), of, among other securities, the Warrants and the Warrant Shares; 

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with
the issuance, registration, transfer, exchange and exercise of the Warrants; 
 WHEREAS, the Company desires to provide for the form, terms
and provisions of the Warrants, including the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants; and 

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent, as provided herein, the legally valid and binding obligations of the Company, and to authorize the execution and delivery of this Warrant Agreement. 

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent
hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Warrant Agreement. 







 2. Warrants. 

2.1 Book-Entry Warrant Certificates. The Warrants shall initially be issuable in book-entry registration only and evidenced by a global
Warrant Certificate (the “Book-Entry Warrant Certificates”). All of the Warrants shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company
(“Depository”) and registered in the name of Cede & Co., as nominee of the Depository. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records
maintained by (i) the Depository or its nominee for each Book-Entry Warrant Certificate or (ii) institutions that have accounts with the Depository (such institutions, with respect to a Warrant in its account, each a “Participant”).
If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for book-entry settlement. In the event that the Warrants are not
eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant
Certificate, and the Company shall instruct the Warrant Agent to deliver to each Holder a warrant certificate in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and signed by, or bear the facsimile
signature of, an authorized signatory. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be
issued with the same effect as if he or she had not ceased to be such at the date of issuance. 
 2.2 Effect of Countersignature.
Unless and until countersigned by the Warrant Agent pursuant to this Warrant Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 

2.3 Registration. 
 2.3.1
Warrant Register. The Warrant Agent shall maintain a register (the “Warrant Register”), for the registration of the original issuance and transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent
shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. 

2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may
deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (“Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of
ownership or other writing on the Warrant certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected
by any notice to the contrary. 
 3. Terms and Exercise of Warrants. 

3.1 Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the
provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock 

  
 2 








 
stated therein, at the price of $3.00 per share of Common Stock, subject to the adjustments provided in Section 4 hereof. The term “Warrant Price” as used in this Warrant
Agreement refers to the price per whole share at which Common Stock may be purchased at the time such Warrant is exercised. 
 3.2
Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date of original issuance and terminating at 5:00 p.m., New York City time, on July 27, 2021 (sixty (60)
months following the closing date of the Public Offering) (“Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this
Warrant Agreement shall cease at the close of business on the Expiration Date. The Company may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide notice of not less than 20 days to
Registered Holders of such extension and that such extension shall be identical in duration among all of the then outstanding Warrants. 

3.3 Exercise of Warrants. 

3.3.1 Payment. Subject to the provisions of the Warrant and this Warrant Agreement, a Warrant, when countersigned by the Company, may
be exercised by the Registered Holder thereof by surrendering it at the office of the Warrant Agent (or, in the case of a global Book-Entry Certificate, properly delivered by the Participant in accordance with the Depository’s procedures), or
at the office of its successor as Warrant Agent, currently being: 
 American Stock Transfer & Trust Company, LLC 

6201 15th Avenue 
 Brooklyn, New
York 11219 
 2nd floor—Reorganization Department 

with the subscription form, as set forth in the Warrant, duly executed, and by paying in full, in lawful money of the United States (or pursuant to the
cashless exercise procedure specified in Section 3.3.3 below, if such cashless exercise procedure is applicable), by certified or bank cashier’s check payable to the order of the Warrant Agent or by wire transfer to the Warrant Agent’s
bank account designated by it, the Warrant Price for each whole Warrant Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Warrant
Shares, and the issuance of the Warrant Shares. 
 3.3.2 Fractional Shares. Notwithstanding any provision to the contrary contained
in this Warrant Agreement, the Company shall not be required to issue any fraction of a Warrant Share in connection with the exercise of Warrants, and in any case where the Registered Holder would be entitled under the terms of the Warrants to
receive a fraction of a Warrant Share upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only the largest whole number of Warrant Shares issuable on such exercise (and such fraction of a Warrant Share will be
disregarded); provided, that if more than one Warrant certificate is presented for exercise at the same time by the same Registered Holder, the number of whole Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the
basis of the aggregate number of Warrant Shares issuable on exercise of all such Warrants. 

  
 3 








 3.3.3 Cashless Exercise. If an effective registration statement is available for the
issuance of the Warrant Shares (as determined by the Company in its sole discretion), then the Warrants may only be exercised, in whole or in part, at such time by means of a cash exercise specified in Section 3.3.1. If at the time of exercise
hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Registered Holders (as determined by the Company in its sole discretion), then the
Warrants may only be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Registered Holders shall be entitled to receive that number of Warrant Shares equal to the quotient obtained by dividing (A-B)
(X) by (A), where: 
 (A) = the per share volume-weighted average price as displayed under the heading ‘‘Bloomberg
VWAP’’ on Bloomberg page ‘‘CFRX <equity> AQR’’ (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the
primary trading session on the VWAP Trading Day (as defined below) immediately preceding the date on which a Registered Holder elects to exercise the Warrant and “cashless exercise” applies (or if such volume weighted average price is
unavailable, the market value of one share of Common Stock on such VWAP Trading Day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by the Company; the
volume-weighted average price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours); 

(B) = the then applicable Warrant Price of the Warrant; and 

(X) = the number of Warrant Shares that would be issuable upon exercise of such Warrant in accordance with the terms of the
Warrant if such exercise were by means of a cash exercise rather than a cashless exercise. 
 As used herein, “VWAP Trading
Day” means a day on which (i) there is no VWAP Market Disruption Event (as defined below) and (ii) trading in the Common Stock generally occurs on the Nasdaq Capital Market or, if the Common Stock is not then listed on the Nasdaq Capital
Market, on the other principal U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on
which the Common Stock is then traded. If the Common Stock (or any other security for which a daily volume-weighted average price must be determined) is not so listed or traded, “VWAP Trading Day” means a “business
day.” “VWAP Market Disruption Event” means (i) a failure by the principal U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted for trading to open for trading during its
regular trading session or (ii) on any scheduled VWAP Trading Day for the Common Stock, the occurrence or existence prior to 1:00 p.m., New York City time, for more than a one half-hour period in the aggregate during regular trading hours, of any
suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Common Stock or in any 

  
 4 








 
options, contracts or futures contracts relating to the Common Stock. The Company will be responsible for determining whether cashless exercise applies to a Warrant exercise and will notify
the Warrant Agent if it does. The Company shall calculate and transmit to the Warrant Agent, and the Warrant Agent shall have no obligation under this section to calculate, the number of Warrant Shares issuable in connection with the cashless
exercise. The Warrant Agent will promptly return the Warrant Price paid by the Registered Holder in the event a cashless exercise applies. 

3.3.4 Issuance of Certificates. No later than three (3) business days following the exercise of any Warrant and the clearance of
the funds in payment of the Warrant Price, the Company shall issue to the Registered Holder of such Warrant a certificate or certificates representing (or deliver electronically through the facilities of the Depository Trust Corporation) the number
of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and, if such Warrant shall not have been exercised or surrendered in full (provided that the holder has
delivered the original physical Warrant Certificate to the Warrant Agent, which delivery shall not include delivery of a notice from the Depository of the transfer or exercise of Warrants in the form of a global Book-Entry Warrant Certificate), a
new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised or surrendered. If fewer than all the Warrants evidenced by a global Book-Entry Warrant Certificate are exercised, a notation shall be made to
the records maintained by the Depository, its nominee for each global Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. Warrants may not be exercised by, or
securities issued to, any Registered Holder in any state in which such exercise or issuance would be unlawful. In the event such exercise would be unlawful with respect to a Registered Holder in any state, the Registered Holder shall not be entitled
to exercise such Warrants and such Warrants may have no value and expire worthless. 
 3.3.5 Valid Issuance. All shares of Common
Stock issued upon the proper exercise or surrender of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and non-assessable. 

3.3.6 Date of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is issued shall, for all
purposes, be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate, except that, if the date of
such surrender 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 such shares at the close of business on the next succeeding date on which the stock transfer books
are open. 
 3.3.7 Holder’s Exercise Limitations. The Company shall not effect any exercise of a Warrant, and a holder shall not
have the right to exercise any portion of a Warrant to the extent that after giving effect to such issuance after exercise, the holder (together with the holder’s affiliates, and any other persons acting as a group together with the holder or
any of the holder’s affiliates), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the holder and its
affiliates shall include the number of shares of Common Stock issuable upon exercise of a Warrant with respect to which such determination is being 

  
 5 








 
made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of a Warrant beneficially owned by the holder or
any of its affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially
owned by the holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 3.3.7, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder, it being acknowledged by the holder that the Company is not representing to the holder that such calculation is in compliance with
Section 13(d) of the Exchange Act and the holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 3.3.7 applies, the determination of whether
a Warrant is exercisable (in relation to other securities owned by the holder together with any affiliates) and of which portion of a Warrant is exercisable shall be in the sole discretion of the holder, and the submission of a subscription form
shall be deemed to be the holder’s determination of whether a Warrant is exercisable (in relation to other securities owned by the holder together with any affiliates) and of which portion of a Warrant is exercisable, in each case subject to
the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 3.3.7, in determining the number of outstanding shares of Common Stock, a holder may rely on the number of outstanding
shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Securities and Exchange Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a
more recent written notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a holder, the Company shall within two Trading Days (as defined below) confirm orally
and in writing to the holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company,
including a Warrants, by the holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 9.99% of the number of shares of the
Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of the Warrant. The Holder, upon not less than 61 days’ prior notice to the Company, may waive the Beneficial Ownership
Limitation provisions of this Section 3.3.7. Any such waiver will not be effective until the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than
in strict conformity with the terms of this Section 3.3.7 to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or
supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of a Warrant.

 4. Adjustments. 

4.1 Stock Dividends, Splits. If, after the date hereof, and subject to the provisions of Section 4.5 below, the number of
outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a forward or reverse split of shares of Common Stock, or other similar event, then, on the effective date of such stock dividend, split or
similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased or decreased in proportion to such increase or decrease in outstanding shares of Common Stock. 

4.2 Aggregation of Shares. If, after the date hereof, and subject to the provisions of Section 4.6, the number of outstanding
shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reclassification or similar event, the number
of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock. 

4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is
adjusted, as provided in Sections 4.1 and 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price, immediately prior to such adjustment, by a fraction, (a) the numerator of which shall be the
number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (b) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 

4.4 Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or
substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common
Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property,
or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of
arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or
party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of the Warrant,
the holder of this Warrant shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section
3.3.7 on the exercise of this Warrant), the number of shares of Common Stock of the Company, if it is the surviving corporation, and 

  
 7 








 
any additional consideration (including any shares in any successor corporation or other entity acquiring the Company) (the “Alternate Consideration”) receivable as a result of
such Fundamental Transaction by a holder of a share of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 3.3.7 on the exercise of this Warrant). For
purposes of any such exercise, the determination of the Warrant Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of common stock in such
Fundamental Transaction, and the Company shall apportion the exercise price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock
are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the holder of the Warrant shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant
following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction that is (1) an all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange
Act, or (3) a Fundamental Transaction involving a person or entity not traded on a national securities exchange, including, but not limited to, the NYSE MKT, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market,
the Company or any Successor Entity (as defined below) shall, at the option of the holder of this Warrant, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction, purchase this Warrant
from the holder by paying to the holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. “Black Scholes Value”
means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and
reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Expiration Date, (B) an expected volatility
equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the trading day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share
used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction (as determined by the Company in good faith) and (D)
a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Expiration Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company
is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 4.4, and to deliver to the holder in exchange for this
Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its
parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price
which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares


  
 8 








 
of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of
such Fundamental Transaction). Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the
Company herein. As used in this Section 4.4, the term “Person” means any foreign or domestic individual, corporation, trust, partnership, joint venture, limited liability company or other private, governmental or self regulatory
entity. 
 4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon
exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such
price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2 or 4.3 the Company shall give
written notice to each Registered Holder, at the last address set forth for such Registered Holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect
the legality or validity of such event. 
 4.6 Form of Warrant. The form of Warrant need not be changed because of any adjustment
pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may, at
any time, in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution
for an outstanding Warrant or otherwise, may be in the form as so changed. 
 5. Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the
Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon the Company’s request. 

5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange
or transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants. 

  
 9 








 5.3 Fractional Warrants. The Warrant Agent shall not be required to effect any
registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a warrant. 
 5.4
Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 
 5.5 Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Warrant Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5,
and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 

6. [RESERVED]. 
 7. Other Provisions Relating to
Rights of Registered Holders of Warrants. 
 7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder
thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect
of the meetings of stockholders or the election of directors of the Company or any other matter. 
 7.2 Lost, Stolen Mutilated or
Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated
Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company,
whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. 
 7.3 Reservation
of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this
Warrant Agreement. The Company will take all such commercially reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any
requirements of the trading market upon which the Common Stock may be listed. 
 8. Concerning the Warrant Agent and Other Matters. 

8.1 Payment of Taxes. The Company will, from time to time, promptly pay all taxes and charges that may be imposed upon the Company or
the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares. 

  
 10 








 8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and
be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint, in writing, a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant
Agent or by the Registered Holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the Registered Holder of any Warrant may apply to the Supreme Court of the State of New York for the
County of New York for the appointment of a successor Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good
standing and having its principal office in the Borough of Manhattan, City and State of New York, and be authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authorities. After
appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any
further act or deed; but, if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority,
powers, and rights of such predecessor Warrant Agent hereunder; and, upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in
and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations. 
 8.2.2 Notice of
Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such
appointment. 
 8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with
which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Warrant Agreement without any further act on the part of the
Company or the Warrant Agent.

 The Warrant entitles the holder thereof to purchase from the Company, commencing upon the
original issuance of the Warrant on July 27, 2016, such number of Shares at the price of $3.00 per share (the “Warrant Price”), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency
of American Stock Transfer & Trust Company, LLC (the “Warrant Agent”), such payment to be made by check made payable to the Warrant Agent (or pursuant to the cashless exercise procedure specified in Section 3.3.3 of
the Warrant Agreement, if such cashless exercise procedure is applicable, but only subject to the conditions set forth herein and in the Warrant Agreement, dated July 27, 2016, between the Company and the Warrant Agent (the “Warrant
Agreement”). In the event of any conflict between the terms of this Warrant Certificate and the terms of the Warrant Agreement, the terms of the Warrant Agreement shall govern. The Warrant Agreement provides that, upon the occurrence of
certain events, the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions. The term Warrant Price as used in this Warrant Certificate refers to the price
per Share at which Shares may be purchased at the time the Warrant is exercised. 
 This Warrant will expire on the date first referenced
above if it is not exercised prior to such date by the registered holder pursuant to the terms of the Warrant Agreement or if it is redeemed by the Company prior to such date as described below. 

No fraction of a Share will be issued upon any exercise of a Warrant. If, upon exercise of a Warrant, a holder would be entitled to receive a

holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Shares for which the Warrant has not been exercised. 

Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by
attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor
and evidencing in the aggregate a like number of Warrants. 
 Upon due presentment for registration of transfer of the Warrant Certificate
at the office or agency of the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate,
subject to the limitations provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge.
