EDGE THERAPEUTICS, INC.


 


Preferred Stock Warrant


 


Edge Therapeutics,
Inc. (the “Company”), for value received, hereby certifies that Maxim Group LLC, or its registered assigns
(the “Registered Holder”), is entitled, subject to the terms of this Series C-1 Preferred Stock Warrant (the
“Warrant”) set forth below, to purchase from the Company, at any time after [•], 2014 (the “Commencement
Date”) and on or before the later of (i) [•], 2019 or five (5) years from the Final Closing Date, as defined in
the Placement Agent Agreement, dated [•], 2014, by and between the Company and the Registered Holder (the “Expiration
Date”), up to [ ] ([ ]) shares of Series C-1 Preferred Stock of the Company (the “Warrant Stock”),
par value $0.00033 per share (the “Preferred Stock”), at a per share exercise price (the “Exercise
Price”) equal to ___________________ per share (subject to adjustment as set forth in Section 2).


 


1.     Exercise.


 


(a)     Method of Exercise.
This Warrant may be exercised by the Registered Holder, in whole or in part, by delivering the form appended hereto as Exhibit A
duly executed by such Registered Holder (the “Exercise Notice”), at the principal office of the Company, or
at such other office or agency as the Company may designate in writing prior to the date of such exercise, accompanied by payment
in full of the Exercise Price payable with respect to the number of shares of Warrant Stock purchased upon such exercise. The Exercise
Price must be paid by cash, check or wire transfer in immediately available funds for the Warrant Stock being purchased by the
Registered Holder, except as provided in Section 1(c).


 


(b)     Effective
Time of Exercise. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of
business on the day on which the Exercise Notice has been delivered to the Company (the “Exercise Date”) as
provided in this Section 1. At such time, the person or persons in whose name or names any certificates for Warrant Stock shall
be issuable upon such exercise as provided in Section 1(d) below shall be deemed to have become the holder or holders of record
of the Warrant Stock represented by such certificates.


 


    	 



    	 



    
(c)     Cashless
Exercise. Notwithstanding any provisions herein to the contrary, in lieu of exercising this Warrant in the manner set forth
in Section 1(a), the Registered Holder may elect to exercise this Warrant, or a portion hereof, and to pay for the Warrant Stock
by way of cashless exercise (a “Cashless Exercise”). If the Registered Holder wishes to effect a cashless exercise,
the Registered Holder shall deliver the Exercise Notice duly executed by such Registered Holder or by such Registered Holder’s
duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may designate
in writing prior to the date of such exercise, in which event the Company shall issue to the Registered Holder the number of shares
of Warrant Stock computed according to the following equation:


 










 


; where


 


X = the number of shares
of Warrant Stock to be issued to the Registered Holder.


 


Y = the Warrant Stock
purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant Stock being
exercised.


 


A = the Fair Market Value
(defined below) of one share of Preferred Stock on the Exercise Date.


 


B = the Exercise Price
(as adjusted pursuant to the provisions of this Warrant).


 


For purposes of this
Section 1(c), the “Fair Market Value” of one share of Preferred Stock on the Exercise Date shall have one of the following
meanings:


 


(1)     the Fair Market
Value shall be determined as follows for the Preferred Stock by calculating the number of shares of Common Stock, par value $0.00033
(the “Common Stock”) the holder would have received upon conversion of the Preferred Stock and multiplying such
converted shares by the Fair Market Value of the Common Stock, which shall be determined by:


 


(a) if the Common
Stock is traded on a national securities exchange, the Fair Market Value shall be deemed to be the average of the Closing Prices
over a five trading day period ending on the Exercise Date. For the purposes of this Warrant, “Closing Price” means
the final price at which one share of Common Stock is traded during any trading day; or


 


(b) if the Common
Stock is traded over-the-counter, the Fair Market Value shall be deemed to be the average of the Closing Price over the five day
period ending on the Exercise Date. If no Closing Price is reported for the Common Stock, the average of the bid and ask prices
for the Common Stock as reported in the over the counter market will be used instead of the Closing Price.


 


(2)if neither (1)(a)
nor (b) is applicable, the Fair Market Value shall be at the commercially reasonable price per share which the Company could obtain
on the Exercise Date from a willing buyer for shares of Preferred Stock sold by the Company, from authorized but unissued shares,
as determined in good faith by the Company’s Board of Directors.


 


For illustration purposes
only, if this Warrant entitles the Registered Holder the right to purchase 100,000 shares of Warrant Stock and the Holder were
to exercise this Warrant for 50,000 shares of Warrant Stock at a time when the Exercise Price was reduced to $1.00 and the Fair
Market Value of each share of Preferred Stock was $2.00 on the Exercise Date, as applicable, the cashless exercise calculation
would be as follows:


 


X = 50,000 ($2.00-$1.00)


$2.00


 


X = 25,000


 



    	 



    	 



    




Therefore, the number
of shares of Warrant Stock to be issued to the Holder after giving effect to the cashless exercise would be 25,000 shares of Warrant
Stock and the Company would issue the Holder a new Warrant to purchase 50,000 shares of Warrant Stock, reflecting the portion of
this Warrant not exercised by the Holder. For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood
and acknowledged that the Warrant Stock issued in the cashless exercise transaction described pursuant to Section 1(c) shall be
deemed to have been acquired by the Holder, and the holding period for the shares of Warrant Stock shall be deemed to have commenced,
on the date of the Registered Holder’s acquisition of the Warrant.


 


(d)     Delivery
to Holder. As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within three
(3) business days thereafter (the “Warrant Stock Delivery Date”), the Company will cause to be issued in the
name of, and delivered to, the Registered Holder, or as such Registered Holder (upon payment by such Registered Holder of any applicable
transfer taxes) may direct:


 


(i)     a certificate
or certificates for the number of shares of Warrant Stock to which such Registered Holder shall be entitled, and


 


(ii)     in case such
exercise is in part only, a new warrant or warrants of like tenor, calling in the aggregate on the face or faces thereof for the
number of shares of Warrant Stock equal (giving effect to any adjustment therein) to the number of such shares called for on the
face of this Warrant minus the number of such shares surrendered for exercise as provided in Section 1(a).


 


2.     Anti-dilution Adjustment.


 


The Registered Holder
shall be entitled to the benefit of all anti-dilution protections contained in the Company’s Restated Certificate of Incorporation,
as amended, and adjustments in the price and number of shares of Common Stock of the Company issuable upon conversion of the Preferred
Stock of the Company for which this Warrant is exercisable which occur prior to the exercise of this Warrant, except in each case,
for such anti-dilution protections or other adjustment to the extent that such protections or adjustments have been waived by the
holders of outstanding Preferred Stock by the requisite vote and/or consent required to waive such protections and adjustments
as to all holders of such Preferred Stock at the time of such waiver. Such anti-dilution protections shall not be restated, amended
or modified in any manner which affects the Holder differently than the holders of preferred stock of the same type as the Preferred
Stock in which this Warrant is convertible, without such Holder’s prior written consent as provided in Section 12.


 


3.     Transfers.


 


(a)     Unregistered
Security. The holder of this Warrant acknowledges that this Warrant has not been registered under the Securities Act and
agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Stock (or
Common Stock) issued upon its exercise in the absence of (i) an effective registration statement under the Securities Act
as to this Warrant or such Warrant Stock and registration or qualification of this Warrant or such Warrant Stock (or Common Stock)
under any applicable U.S. federal or state securities law then in effect or (ii) an opinion of counsel, reasonably satisfactory
to the Company, that such registration and qualification are not required.


 



    	 



    	 



    




(b)     Transferability.
Subject to the provisions of Section 3(a) hereof, this Warrant and all rights hereunder are transferable, in whole or in part on
and after the Commencement Date; provided, however, subject to the provisions of Section 3(a) hereof, this Warrant and all rights
hereunder are transferable, in whole or in part immediately upon issuance to (i) any entity controlling, controlled by or under
common control of the Registered Holder, or (ii) to any successor, officer, manager or member of the Registered Holder (or to any
officer, manager or member of any successor to the Registered Holder) by surrendering the Warrant with a properly executed assignment
(in the form of Exhibit B hereto) at the principal office of the Company.


 


(c)     Warrant
Register. The Company will maintain a register containing the names and addresses of the Registered Holders of this Warrant.
Until any transfer of this Warrant is made in the warrant register, the Company may treat the Registered Holder of this Warrant
as the absolute owner hereof for all purposes. Any Registered Holder may change such Registered Holder’s address as shown
on the warrant register by written notice to the Company requesting such change.


 


4.     Registration
Rights. 


 


(a)     Provided that
the Common Stock or Preferred Stock underlying the Warrants (the “Registrable Securities”) have not been registered
or are not otherwise freely tradable without restriction pursuant to Rule 144 promulgated under the Securities Act, if at any time
after the Company’s initial public offering under the Securities Act, the Company proposes to register any of its securities
under the Securities Act (other than by a registration in connection with an acquisition in a manner which would not permit registration
of the securities for sale to the public, or a registration on Form S-8 or Form S-4, or any successor forms thereto), then the
Company will at such time give prompt written notice to the Registered Holder of its intention to do so. Upon the written request
or request via electronic mail of the Registered Holder, made within ten (10) days after the receipt of such notice, to include
any of the Registrable Securities in such registration, the Company will, subject to the terms of this Agreement, use its commercially
reasonable best efforts to effect the registration under the Securities Act of the Registrable Securities but in no event later
than 180 days from the date of such request.  The Company shall have the right to terminate or withdraw any registration initiated
by it under this Section 4(a) before the effective date of such registration, whether or not the Registered Holder has elected
to include Registrable Securities in such registration. In connection with any offering involving an underwriting of shares of
the Company’s capital stock pursuant to this Section 4(a), the Company shall not be required to include any of the Registered
Holder’s Registrable Securities in such underwriting unless the Registered Holder accepts the terms of the underwriting as
agreed upon between the Company and its underwriters or if the Registered Holder has not provided the information necessary to
be included in the registration statement.


 


(b)     Commencing one
(1) year after the Company has been subject to the requirements of Section 12 or Section 15(d) of the Securities Exchange Act of
1934, as amended (the “Exchange Act”), the Registered Holder is entitled to one “demand” registration right.
Upon receipt of such demand request by the Company from the Registered Holder, the Company shall file a registration statement
on Form S-3 (“Form S-3”) or, if Form S-3 is not available, on any other appropriate form, including Form S-1 and
cause such registration statement to become effected (as defined in Section 4(d)) in an expeditious manner. Furthermore, if at
any time after [•], 2014 until one (1) year after the Company has been subject to the requirements of Section 12 or Section
15(d) of the Exchange Act, the Company closes on any other financing that grants to other such investors more favorable “demand”
registration rights than granted to the Registered Holder in this Section 4(b), the Registered Holder shall be entitled to such
more favorable “demand” rights granted to such investors.


 


(c)     Registration of
Registrable Securities under this Section 4 shall be on such appropriate registration form: (i) as shall be selected by the Company,
and (ii) as shall permit the public disposition of such Registrable Securities in accordance with this Section 4. The Company agrees
to include in any such registration statement all information which the requesting holders of Registrable Securities shall reasonably
request, which is required to be contained therein. The Company will pay all Registration Expenses in connection with each registration
of Registrable Securities pursuant to this Section 4, excluding underwriting discounts and commission, and fees and expenses of
counsel to the Registered Holders.


 


(d)     A registration
requested pursuant to this Section 4 shall not be deemed to have been effected: (i) unless a registration statement with respect
thereto has become effective or (ii) if, after it has become effective, such registration is interfered with by any stop order,
injunction or other order or requirement of the Securities and Exchange Commission (the “SEC”) or other governmental
agency or court of competent jurisdiction for any reason, other than by reason of some act or omission by a holder of Registrable
Securities.


 


5.     Termination.
This Warrant (and the right to purchase securities upon exercise hereof) shall terminate at 5:00 p.m., Eastern Time, on the Expiration
Date.


 


6.     Notices
of Certain Transactions. In case:


 


(a)     the Company shall
take a record of the holders of its Preferred Stock (or other stock or securities at the time deliverable upon the exercise of
this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right
to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, to subscribe
for or purchase any shares of stock of any class or any other securities, or to receive any other right, or


 


(b)     of any capital
reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger of the Company,
any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the
Company is the surviving entity), or any transfer of all or substantially all of the assets of the Company, or


 


(c)     of the voluntary
or involuntary dissolution, liquidation or winding-up of the Company,


 


then, and in each such case, the Company
will mail or cause to be mailed to the Registered Holder of this Warrant a notice specifying, as the case may be, (i) the date
on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character
of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation,
merger, transfer, dissolution, liquidation, winding-up is to take place, and the time, if any is to be fixed, as of which the holders
of record of Preferred Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification,
consolidation, merger, transfer, dissolution, liquidation or winding-up) are to be determined. Failure to send such notice
shall not act to invalidate any such transaction.


 


    	 



    	 



    
7.     Reservation
of Stock. The Company covenants that at all times it will have authorized, reserve and keep available, solely for the issuance
and delivery upon the exercise of this Warrant, such shares of Warrant Stock and other stock, securities and property, as from
time to time shall be issuable upon the exercise of this Warrant or conversion of the Preferred Stock. The Company covenants that
all Warrant Stock that may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of
the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue). The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers
who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the shares of
Warrant Stock upon the exercise of the purchase rights under this Warrant by the Registered Holder. The Company will take all such
reasonable action as may be necessary to assure that such Warrant Stock may be issued as provided herein without violation of any
applicable law or regulation.


 







8.     Replacement
of Warrants. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation
of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement (with surety if reasonably
required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of
this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor.


 


9.     Notices.
Any notice required or permitted by this Warrant shall be in writing and shall be deemed duly given upon receipt, when delivered
personally or by courier, overnight delivery service, confirmed facsimile or electronic mail, or 48 hours after being deposited
in the regular mail as certified or registered mail (airmail if sent internationally) with postage prepaid, addressed (a) if to
the Registered Holder, to the address of the Registered Holder most recently furnished in writing to the Company and (b) if to
the Company, to the address set forth on the signature page of this Warrant or as subsequently modified by written notice to the
Registered Holder.


 


10.     No Rights
as Stockholder. Until the exercise of this Warrant, the Registered Holder of this Warrant shall not have or exercise any
rights by virtue hereof as a stockholder of the Company.


 


11.     No Fractional
Shares. No fractional shares of Preferred Stock will be issued in connection with any exercise hereunder. In lieu of any
fractional shares which would otherwise be issuable, the Company shall round the amount of Warrant Stock issuable to the nearest
whole share.


 


12.     Consent,
Amendment or Waiver. Any term of this Warrant may be amended or waived upon written consent of the Company and the Registered
Holders of a majority of the Warrant Stock issuable upon the issued and outstanding Warrants.


 


13.     Headings.
The headings in this Warrant are for purposes of reference only and shall not limit or otherwise affect the meaning of any provision
of this Warrant.


 


14.     Governing
Law. This Warrant and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall
be governed, construed and interpreted in accordance with the laws of the State of New York, without giving effect to principles
of conflicts of law.


 


    	 



    	 



    
15.     Representations and Warranties
of the Company. This Warrant has been entered into by the Registered Holder in reliance upon the following representations
and covenants of the Company as of the Date of Issuance:


 


(a)     Authorization.

The Warrant Stock is duly authorized and reserved for issuance, and when issued and delivered in accordance with the terms of this
Warrant will be duly and validly issued, fully paid and nonassessable.


 


(c)     No Conflict. The
execution and delivery of this Warrant do not, and the consummation of the transactions contemplated hereby will not, conflict
with, or result in any violation of, breach or default (with or without notice or lapse of time, or both), or give rise to a right
of termination, cancellation or acceleration of any obligation or to a loss of a material benefit, under, any provision of the
Restated Certificate of Incorporation or Bylaws of the Company or any order, decree, statute, law, ordinance, rule, listing requirement
or regulation applicable to the Company, its properties or assets, which conflict, violation, default or right would have a material
adverse effect on the business, properties, prospects, financial condition or operations of the Company.


 


16.     No Impairment.
The Company will not, by amendment of its Restated Certificate of Incorporation or through reorganization, consolidation, merger,
dissolution, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, but will (subject to Section 12 above) at all times in good faith assist in the carrying out of all such terms
and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Registered Holder
of this Warrant against impairment.
