EDGE THERAPEUTICS, INC.

 

Preferred Stock Warrant

 

Edge Therapeutics,
Inc. (the “Company”), for value received, hereby certifies that Maxim Partners LLC, or its registered assigns
(the “Registered Holder”), is entitled, subject to the terms of this Series C Preferred Stock Warrant (the “Warrant”)
set forth below, to purchase from the Company, at any time after , 2013 (the “Commencement Date”) and
on or before the later of (i) , 2018 or five (5) years from the Final Closing Date, as defined in the Placement Agent Agreement,
dated March 18, 2013, by and between the Company and the Registered Holder (the “Expiration Date”), up to (
) shares of Series C 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 $4.235
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:

 

X = Y * (A-B)

     A

      where

 

; 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.

 

    	2

    	 

    

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.

 

    	4

    	 

    

(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 March 15, 2013 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

such reasonable action as may be necessary to assure that such Warrant Stock may be issued as provided herein without violation

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.

of this Warrant.

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

WARRANT AGREEMENT

 

To Purchase Shares of Preferred Stock of

 

EDGE THERAPEUTICS, INC.

 

Dated as of August
28, 2014 (the “Effective Date”)

 

WHEREAS, Edge Therapeutics, Inc., a Delaware corporation, has
entered into a Loan and Security Agreement of even date herewith (the “Loan Agreement”) with Hercules Technology
Growth Capital, Inc., a Maryland corporation, in its capacity as administrative agent (the “Warrantholder”)
and the other lender parties thereto;

 

WHEREAS, the Company (as defined below) desires to grant to
Warrantholder, in consideration for, among other things, the financial accommodations provided for in the Loan Agreement, the right
to purchase shares of Preferred Stock (as defined below) pursuant to this Warrant Agreement (the “Agreement”);

 

NOW, THEREFORE, in consideration of the Warrantholder executing
and delivering the Loan Agreement and providing the financial accommodations contemplated therein, and in consideration of the
mutual covenants and agreements contained herein, the Company and Warrantholder agree as follows:

 

SECTION 1.            
GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

 

For value received, the Company hereby grants to the Warrantholder,
and the Warrantholder is entitled, upon the terms and subject to the conditions hereinafter set forth, to subscribe for and purchase,
from the Company, an aggregate number of fully paid and non-assessable shares of the Preferred Stock equal to the quotient derived
by dividing (a) the Warrant Coverage (as defined below) by (b) the Exercise Price (defined below). The Exercise Price of such shares
is subject to adjustment as provided in Section 8.

 

The Company represents and warrants to the Warrantholder that
the Company is contemplating the authorization and issuance of a new round of its preferred stock which shall be for Series C-1
Preferred Stock of the Company.  In the event on or after the Effective Date but on or before December 31, 2014 the Company
authorizes and issues shares of the Company’s Series C-1 Preferred Stock and the aggregate net sales proceeds from such issuance
are at least $2,000,000, then this Warrant shall automatically be deemed to be initially exercisable for the Company’s Series
C-1 Preferred Stock at the Series C-1 Price (as defined below) instead of the Company’s Series C Preferred Stock.  The
Company shall provide the Warrantholder with appropriate evidence and documentation of such Series C-1 Preferred Stock issuance. 
Upon the request of the Warrantholder, within thirty (30) days of the Company’s initial issuance of its Series C-1 Preferred
Stock the Company shall execute and delivery to the Warrantholder an amendment to this Warrant or an amended and restated Warrant
reflecting such changes along with conforming changes to the Warrant to reflect the change from Series C Preferred Stock to Series
C-1 Preferred Stock and to change to the Exercise Price accordingly.  “Series C-1 Price” means the lowest
price per share for which the Company’s Series C-1 Preferred are sold or issued by the Company.  In the event that the
Company does not on or before December 31, 2014 authorize and issue shares of the Company’s Series C-1 Preferred Stock and
receive aggregate net sales proceeds from such issuance of at least $2,000,000, then this Warrant shall remain initially exercisable
for the Company’s Series C Preferred Stock at the Series C Price.

 

As used herein, the following terms shall
have the following meanings:

 

“Act” means the Securities Act
of 1933, as amended.

 

“Company” means Edge Therapeutics,
Inc., a Delaware corporation, and any successor or surviving entity that assumes the obligations of the Company under this Agreement
pursuant to Section 8(a).

 

“Charter” means the Company’s
Articles of Incorporation, Certificate of Incorporation or other constitutional document, as may be amended from time to time.

 

“Common Stock” means the Company’s
common stock, $0.00033 par value per share.

    	1

    	 

    

 

“Exercise Price”
means the Series C Price, subject to adjustment from time to time in accordance with the provisions of this Warrant; provided,
that if the Next Preferred Round Price shall be lower than the then-effective Exercise Price, then “Exercise Price”
shall mean the Next Preferred Round Price from and after the closing of the Next Preferred Round, subject to adjustment thereafter
from time to time in accordance with the provisions of this Warrant.

 

“Initial Public Offering” means
the initial underwritten public offering of the Company’s Common Stock pursuant to a registration statement under the Act,

SECTION 2.            
TERM OF THE AGREEMENT.

 

Except as otherwise provided for herein, the term of this Agreement
and the right to purchase Preferred Stock as granted herein (the “Warrant”) shall commence on the Effective
Date and shall be exercisable for a period ending upon the later to occur of (i) ten (10) years from the Effective Date; or (ii)
if the Initial Public Offering shall be consummated on or before the tenth (10th) anniversary of the Effective Date,
five (5) years after the Initial Public Offering.

 

SECTION 3.            
EXERCISE OF THE PURCHASE RIGHTS.

 

(a)                
Exercise. The purchase rights set forth in this Agreement are exercisable by the Warrantholder, in whole or in part,
at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the Company at its
principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”),
duly completed and executed. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance
with the terms set forth below, and in no event later than three (3) days thereafter, the Company shall issue to the Warrantholder
a certificate for the number of shares of Preferred Stock purchased and shall execute the acknowledgment of exercise in the form
attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which
remain subject to future purchases, if any.

 

The Purchase Price may be paid at the Warrantholder’s
election either (i) by cash or check, or (ii) by surrender of all or a portion of the Warrant for shares of Preferred Stock to
be exercised under this Agreement and, if applicable, an amended Agreement representing the remaining number of shares purchasable
hereunder, as determined below (“Net Issuance”). If the Warrantholder elects the Net Issuance method, the Company
will issue Preferred Stock in accordance with the following formula:

 

X  =  Y(A-B)

A

 

	Where:	X = the number
of shares of Preferred Stock to be issued to the Warrantholder.
	 	 
	 	Y = the number of shares
of Preferred Stock requested to be exercised under this Agreement.
	 	 
	 	A = the fair market value
of one (1) share of Preferred Stock at the time of issuance of such shares of Preferred Stock.
	 	 
	 	B = the Exercise Price.

 

For purposes of the above calculation, current fair market value
of Preferred Stock shall mean with respect to each share of Preferred Stock:

 

(i)                  
if the exercise is in connection with an Initial Public Offering, and if the Company’s Registration Statement relating
to such Initial Public Offering has been declared effective by the SEC, then the fair market value per share shall be the product
of (x) the initial “Price to Public” of the Common Stock specified in the final prospectus with respect to the offering
and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise;

 

(ii)                
if the exercise is after, and not in connection with an Initial Public Offering, and:

 

(A)               
if the Common Stock is traded on a securities exchange, the fair market value shall be deemed to be the product of (x) the
prior day closing price before the day the current fair market value of the securities is being determined and (y) the number of
shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise; or

 

(B)               
if the Common Stock is traded over-the-counter, the fair market value shall be deemed to be the product of (x) the prior
day closing bid and asked price quoted on the NASDAQ system (or similar system) before the day the current fair market value of
the securities is being determined and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible
at the time of such exercise;

 

(iii)               
if at any time the Common Stock is not listed on any securities exchange or quoted in the NASDAQ National Market or the
over-the-counter market, the current fair market value of Preferred Stock shall be determined in good faith by its Board of Directors,
unless the Company shall become subject to a Merger Event, in which case the fair market value of Preferred Stock shall be deemed
to be the per share value received by the holders of the Company’s Preferred Stock on a common equivalent basis pursuant
to such Merger Event.

 

Upon partial exercise by either cash or Net Issuance, the Company
shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder. All other terms and
conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective
Date hereof.

    	3

    	 

    

 

(b)                
Exercise Prior to Expiration. To the extent this Agreement is not previously exercised as to all Preferred Stock
subject hereto, and if the fair market value of one share of the Preferred Stock is greater than the Exercise Price then in effect,
this Agreement shall be deemed automatically exercised pursuant to Section 3(a) (even if not surrendered) immediately before its
expiration. For purposes of such automatic exercise, the fair market value of one share of the Preferred Stock upon such expiration
shall be determined pursuant to Section 3(a). To the extent this Agreement or any portion thereof is deemed automatically exercised
pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the number of shares of Preferred Stock,
if any, the Warrantholder is to receive by reason of such automatic exercise.

 

SECTION 4.            
RESERVATION OF SHARES.

 

During the term of this Agreement, the Company will at all times
have authorized and reserved a sufficient number of shares of its Preferred Stock to provide for the exercise of the rights to
purchase Preferred Stock as provided for herein, and shall have authorized and reserved a sufficient number of shares of its Common
Stock to provide for the conversion of the shares of Preferred Stock issuable hereunder.

 

SECTION 5.            
NO FRACTIONAL SHARES OR SCRIP.

 

No fractional shares or scrip representing fractional shares
shall be issued upon the exercise of this Agreement, but in lieu of such fractional shares the Company shall make a cash payment
therefor upon the basis of the then fair market value of one share of Preferred Stock.

 

SECTION 6.            
NO RIGHTS AS SHAREHOLDER/STOCKHOLDER.

 

This Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder/stockholder of the Company prior to the exercise of this Agreement.

 

SECTION 7.            
WARRANTHOLDER REGISTRY.

 

The Company shall maintain a registry showing the name and address
of the registered holder of this Agreement. Warrantholder’s initial address, for purposes of such registry, is set forth
below Warrantholder’s signature on this Agreement. Warrantholder may change such address by giving written notice of such
changed address to the Company.

 

SECTION 8.            
ADJUSTMENT RIGHTS.

 

The Exercise Price and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

 

(a)                
Merger Event. If at any time there shall be Merger Event, then, as a part of such Merger Event, lawful provision
shall be made so that the Warrantholder shall thereafter be entitled to receive, upon exercise of this Agreement, the number of
shares of preferred stock or other securities or property (collectively, “Reference Property”) that the Warrantholder
would have received in connection with such Merger Event if Warrantholder had exercised this Agreement immediately prior to the
Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of Directors)
shall be made in the application of the provisions of this Agreement with respect to the rights and interests of the Warrantholder
after the Merger Event to the end that the provisions of this Agreement (including adjustments of the Exercise Price and adjustments
to ensure that the provisions of this Section 8 shall thereafter be applicable, as nearly as possible, to the purchase rights under
this Agreement in relation to any Reference Property thereafter acquirable upon exercise of such purchase rights) shall continue
to be applicable in their entirety, and to the greatest extent possible. Without limiting the foregoing, in connection with any
Merger Event, upon the closing thereof, the successor or surviving entity shall assume the obligations of this Agreement;
provided that the foregoing assumption requirement shall not apply if the consideration to be paid
for or in respect of the outstanding shares of Preferred Stock in such Merger Event consists solely of cash and/or readily marketable
securities. In connection with a Merger Event and upon Warrantholder’s written election to the Company, the Company shall
cause this Warrant Agreement to be exchanged for the consideration that Warrantholder would have received if Warrantholder had
chosen to exercise its right to have shares issued pursuant to the Net Issuance provisions of this Warrant Agreement without actually
exercising such right, acquiring such shares and exchanging such shares for such consideration. The provisions of this Section
8(a) shall similarly apply to successive Merger Events.

 

(b)                
Reclassification of Shares. Except for a Merger Event subject to Section 8(a), and subject to Section 8(f), if the
Company at any time shall, by combination, reclassification, reorganization, exchange or subdivision of securities or otherwise,
change any of the securities as to which purchase rights under this Agreement exist into the same or a different number of securities
of any other class or classes, this Agreement shall thereafter represent the right to acquire such number and kind of securities
as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights
under this Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change. The provisions
of this Section 8(b) shall similarly apply to successive combination, reclassification, exchange, subdivision or other change.

 

(c)                
Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide its Preferred Stock,
(i) in the case of a subdivision, the Exercise Price shall be proportionately decreased and the number of shares of Preferred Stock
issuable hereunder shall be proportionately increased, or (ii) in the case of a combination, the Exercise Price shall be proportionately
increased and the number of shares of Preferred Stock issuable hereunder shall be proportionately decreased.

    	4

    	 

    

 

(d)                
Stock Dividends. If the Company at any time while this Agreement is outstanding and unexpired shall:

 

(i)                  
pay a dividend with respect to the Preferred Stock payable in Preferred Stock, then the Exercise Price shall be adjusted,
from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined
by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of
which shall be the total number of shares of Preferred Stock outstanding immediately prior to such dividend or distribution, and
(B) the denominator of which shall be the total number of shares of Preferred Stock outstanding immediately after such dividend
or distribution; or

 

(ii)                
make any other distribution with respect to Preferred Stock (or stock into which the Preferred Stock is convertible), except
any distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision shall
be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a proportionate share
of any such distribution as though it were the holder of the Preferred Stock (or other stock for which the Preferred Stock is convertible)
as of the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution.

 

(e)                
Antidilution Rights. Additional antidilution rights applicable to the Preferred Stock purchasable hereunder are as
set forth in the Charter and shall be applicable with respect to the Preferred Stock issuable hereunder. The Company shall promptly
provide the Warrantholder with any restatement, amendment, modification or waiver of the Charter; provided, that no such
amendment, modification or waiver shall impair or reduce the antidilution rights applicable to the Preferred Stock as of the date
hereof, without the Warrantholder’s consent, unless such amendment, modification or waiver affects the rights of Warrantholder
with respect to the Preferred Stock in the same manner as it affects all other holders of Preferred Stock. The Company shall provide
Warrantholder with prior written notice of any issuance of its stock or other equity security to occur after the Effective Date
of this Agreement (other than (i) stock issued as a dividend upon the Company’s Series C Preferred Stock or Series C-1 Preferred
Stock, and (ii) stock, options and other securities issued pursuant to any incentive equity plan of the Company), which notice
shall include (a) the price at which such stock or security is to be sold, (b) the number of shares to be issued, and (c)
such other information as necessary for Warrantholder to determine if a dilutive event has occurred. For the avoidance of doubt,
there shall be no duplicate anti-dilution adjustment pursuant to this subsection (e), the forgoing subsection (d) and the Charter.

 

(f)                 
Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon its stock, whether in
stock, cash, property or other securities, other than stock dividends upon its Series C Preferred Stock or Series C-1 Preferred
Stock; (ii) there shall be any Merger Event; (iv) there shall be an Initial Public Offering; (iii) the Company shall sell, lease,
license or otherwise transfer all or substantially all of its assets; or (iv) there shall be any voluntary dissolution, liquidation
or winding up of the Company; then, in connection with each such event, the Company shall send to the Warrantholder: (A) at least
thirty (30) days’ prior written notice of the date on which the books of the Company shall close or a record shall be taken
for such dividend, distribution, subscription rights (specifying the date on which the holders of Preferred Stock shall be entitled
thereto) or for determining rights to vote in respect of such Merger Event, dissolution, liquidation or winding up; (B) in the
case of any such Merger Event, sale, lease, license or other transfer of all or substantially all assets, dissolution, liquidation
or winding up, at least thirty (30) days’ prior written notice of the date when the same shall take place (and specifying
the date on which the holders of Preferred Stock shall be entitled to exchange their Preferred Stock for securities or other property
deliverable upon such Merger Event, dissolution, liquidation or winding up); and (C) in the case of an Initial Public Offering,
the Company shall give the Warrantholder at least thirty (30) days’ written notice prior to the effective date thereof.

 

Each such written notice shall set forth, in reasonable detail,
(i) the event requiring the notice, and (ii) if any adjustment is required to be made, (A) the amount of such adjustment, (B) the
method by which such adjustment was calculated, (C) the adjusted Exercise Price (if the Exercise Price has been adjusted), and
(D) the number of shares subject to purchase hereunder after giving effect to such adjustment, and shall be given in accordance
with Section 12(g) below.

 

SECTION 9.            
REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

 

(a)                
Reservation of Preferred Stock. The Preferred Stock issuable upon exercise of the Warrantholder’s rights has
been or, in the case of Preferred Stock issuable in the Next Round, will be duly and validly reserved and, when issued in accordance
with the provisions of this Agreement, will be validly issued, fully paid and non-assessable, and will be free of any taxes, liens,
charges or encumbrances of any nature whatsoever; provided, that the Preferred Stock issuable pursuant to this Agreement
may be subject to restrictions on transfer under state and/or federal securities laws. The Company has made available to the Warrantholder
true, correct and complete copies of its Charter and current bylaws. The issuance of certificates for shares of Preferred Stock
upon exercise of this Agreement shall be made without charge to the Warrantholder for any issuance tax in respect thereof (other
than income taxes of the Warrantholder), or other cost incurred by the Company in connection with such exercise and the related
issuance of shares of Preferred Stock; provided, that the Company shall not be required to pay any tax which may be payable
in respect of any transfer and the issuance and delivery of any certificate in a name other than that of the Warrantholder.

of the Company hereunder, including the issuance to Warrantholder of the right to acquire the shares of Preferred Stock and the
Common Stock into which it may be converted, have been duly authorized by all necessary corporate action on the part of the Company.
This Agreement: (1) does not violate the Company’s Charter or current bylaws; (2) does not contravene any law or governmental
rule, regulation or order applicable to it; and (3) does not and will not contravene any provision of, or constitute a default
under, any indenture, mortgage, contract or other instrument to which it is a party or by which it is bound. This Agreement constitutes

thereby.

(i)                  
The authorized capital of the Company consists of (A) 17,500,000 shares of Common Stock, of which 2,310,000 shares are issued

shall be Common Stock, shall have the “Piggyback,” and S-3 registration rights pursuant to and as set forth in the

SECTION 10.        
REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

 

This Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder:

 

(a)                
Investment Purpose. The right to acquire Preferred Stock is being acquired for investment and not with a view to
the sale or distribution of any part thereof, and the Warrantholder has no present intention of selling or engaging in any public
distribution of such rights or the Preferred Stock except pursuant to an effective registration statement or an exemption from
the registration requirements of the Act.

 

(b)                
Private Issue. The Warrantholder understands (i) that the Preferred Stock issuable upon exercise of this Agreement
is not registered under the Act or qualified under applicable state securities laws on the ground that the issuance contemplated
by this Agreement will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s
reliance on such exemption is predicated on the representations set forth in this Section 10.

 

(c)                
Financial Risk. The Warrantholder has such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of its investment.

 

(d)                
Risk of No Registration. The Warrantholder understands that if the Company does not register with the SEC pursuant
to Section 12 of the Securities Exchange Act of 1934 (the “1934 Act”), or file reports pursuant to Section 15(d)
of the 1934 Act, or if a registration statement covering the securities under the Act is not in effect when it desires to sell
(i) the rights to purchase Preferred Stock pursuant to this Agreement or (ii) the Preferred Stock issuable upon exercise of the
right to purchase, it may be required to hold such securities for an indefinite period. The Warrantholder also understands that
any sale of (A) its rights hereunder to purchase Preferred Stock or (B) Preferred Stock issued or issuable hereunder
which might be made by it in reliance upon Rule 144 under the Act may be made only in accordance with the terms and conditions
of that Rule.

 

(e)                
Accredited Investor. Warrantholder is an “accredited investor” within the meaning of the Securities and
Exchange Rule 501 of Regulation D, as presently in effect.

 

SECTION 11.        
TRANSFERS.

 

Subject to compliance with applicable federal and state securities
laws, this Agreement and all rights hereunder are transferable, in whole or in part, without charge to the holder hereof (except
for transfer taxes) upon surrender of this Agreement properly endorsed, provided, however, that (i) any successor
transferee makes the representations and covenants set forth in Section 10 and agrees in writing to be bound by the covenants,
terms and conditions of this Warrant and (ii) the Warrantholder agrees not to transfer this Agreement and any rights hereunder
to a competitor of the Company so long as there are no Events of Default under the Loan Agreement. Each taker and holder of this
Agreement, by taking or holding the same, consents and agrees that this Agreement, when endorsed in blank, shall be deemed negotiable,
and that the holder hereof, when this Agreement shall have been so endorsed and its transfer recorded on the Company’s books,
shall be treated by the Company and all other persons dealing with this Agreement as the absolute owner hereof for any purpose
and as the person entitled to exercise the rights represented by this Agreement. The transfer of this Agreement shall be recorded
on the books of the Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the
“Transfer Notice”), at its principal offices and the payment to the Company of all transfer taxes and other
governmental charges imposed on such transfer. Until the Company receives such Transfer Notice, the Company may treat the registered
owner hereof as the owner for all purposes.

 

SECTION 12.        
MISCELLANEOUS.

 

(a)                
Effective Date. The provisions of this Agreement shall be construed and shall be given effect in all respects as
if it had been executed and delivered by the Company on the date hereof. This Agreement shall be binding upon any successors or
assigns of the Company.

 

(b)                
Remedies. In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its
rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any
such default, and/or an action for specific performance for any default where Warrantholder will not have an adequate remedy at
law and where damages will not be readily ascertainable. The Company expressly agrees that it shall not oppose an application by
the Warrantholder or any other person entitled to the benefit of this Agreement requiring specific performance of any or all provisions
hereof or enjoining the Company from continuing to commit any such breach of this Agreement.

 

(c)               
No Impairment of Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek
to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the
rights of the Warrantholder against impairment. The foregoing notwithstanding, the Company shall
not have been deemed to have impaired the Warrantholder’s rights hereunder: (i) if it amends its Charter, or the holders
of the Company’s other series of preferred stock waive rights thereunder, in a manner that does not affect the Preferred
Stock differently from the effect that such amendments or waivers have generally on the rights, preferences, privileges or restrictions
of the other shares of the same class of stock, or (ii) if the Company, through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action, affects Warrantholder’s rights hereunder
in a manner that does not affect the Preferred Stock differently from the effect that such transactions have generally on the rights,
preferences, privileges or restrictions of the other shares of the same class of stock.

 

(d)                
Additional Documents. The Company, upon execution of this Agreement, shall provide the Warrantholder with certified
resolutions with respect to the representations, warranties and covenants set forth in Sections 9(a), 9(c) and 9(e). The Company
shall also supply such other documents as the Warrantholder may from time to time reasonably request.

(e)                
Attorney’s Fees. In any litigation, arbitration or court proceeding between the Company and the Warrantholder
relating hereto, the prevailing party shall be entitled to attorneys’ fees and expenses and all costs of proceedings incurred
in enforcing this Agreement. For the purposes of this Section 12(e), attorneys’ fees shall include without limitation fees
incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding or other activity
of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and third party examinations; and (v)
post-judgment motions and proceedings of any kind, including without limitation any activity taken to collect or enforce any judgment.

 

(f)                 
Severability. In the event any one or more of the provisions of this Agreement shall for any reason be held invalid,
illegal or unenforceable, the remaining provisions of this Agreement shall be unimpaired, and the invalid, illegal or unenforceable
provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes closest to the intention
of the parties underlying the invalid, illegal or unenforceable provision.

 

(g)                
Notices. Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service
of process or other communication that is required, contemplated, or permitted under this Agreement or with respect to the subject
matter hereof shall be in writing, which shall include email communication, and shall be deemed to have been validly served, given,
delivered, and received upon the earlier of: (i) the day of transmission by facsimile, email communication, or hand delivery
if transmission or delivery occurs on a business day at or before 5:00 pm in the time zone of the recipient, or, if transmission
or delivery occurs on a non-business day or after such time, the first business day thereafter, or the first business day after
deposit with an overnight express service or overnight mail delivery service; or (ii) the third calendar day after deposit
in the United States mails, with proper first class postage prepaid, and shall be addressed to the party to be notified as follows:

(h)                
Entire Agreement; Amendments. This Agreement constitutes the entire agreement and understanding of the parties hereto
in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term sheets, letters,
negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof (including Warrantholder’s
proposal letter dated July 21, 2014). None of the terms of this Agreement may be amended except by an instrument executed by each
of the parties hereto.

 

(i)                  
Headings. The various headings in this Agreement are inserted for convenience only and shall not affect the meaning
or interpretation of this Agreement or any provisions hereof.

 

(j)                 
No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement.
In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly
by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship
of any provisions of this Agreement.

 

(k)                
No Waiver. No omission or delay by Warrantholder at any time to enforce any right or remedy reserved to it, or to
require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, shall be a waiver
of any such right or remedy to which Warrantholder is entitled, nor shall it in any way affect the right of Warrantholder to enforce
such provisions thereafter.

 

(l)                  
Survival. All agreements, representations and warranties contained in this Agreement or in any document delivered
pursuant hereto shall be for the benefit of Warrantholder and shall survive the execution and delivery of this Agreement and the
expiration or other termination of this Agreement.

 

(m)              
Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the
State of New York, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

 

(n)                
Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement may
be brought in any state or federal court of competent jurisdiction located in the State of New York. By execution and delivery
of this Agreement, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in New York County, State
of New York; (b) waives any objection as to jurisdiction or venue in New York County, State of New York; (c) agrees not to assert
any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment
rendered thereby in connection with this Agreement. Service of process on any party hereto in any action arising out of or relating
to this Agreement shall be effective if given in accordance with the requirements for notice set forth in Section 12(g), and shall
be deemed effective and received as set forth in Section 12(g). Nothing herein shall affect the right to serve process in any other
manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

 

(o)                
Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most
quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to
apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws.
EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM,
CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST
WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such Claims,
including Claims that involve Persons other than the Company and Warrantholder; Claims that arise out of or are in any way connected
to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract, specific performance,
or any equitable or legal relief of any kind, arising out of this Agreement.

 

(p)                
Prejudgment Relief. In the event Claims are to be resolved by arbitration, either party may seek from a court of
competent jurisdiction identified in Section 12(n), any prejudgment order, writ or other relief and have such prejudgment order,
writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution
by judicial reference.

 

(q)                
Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number
of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original,
but all of which counterparts shall constitute but one and the same instrument.
