 NOVUME SOLUTIONS, INC. 

Common Stock Purchase Warrant 

Novume Solutions, Inc., a Delaware corporation (the “Company”), for value received, hereby certifies that
                     (the “Registered Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at
any time after the date hereof and on or before the Expiration Date (as defined in Section 8 below) shares of the Company’s Common Stock, par value $0.0001 per share (“Common Stock”), at an exercise price per share (the
“Exercise Price”) equal to $2.58. The shares of Common Stock issuable upon exercise of this Common Stock Purchase Warrant (the “Warrant”) are referred to hereinafter as the “Warrant Stock”. 

This Warrant is issued to the Registered Holder pursuant to and is subject to the terms and conditions of the Merger Agreement by and among
the Company, KeyStone Solutions, Inc., a Delaware corporation (“KeyStone”), Brekford Corp., a Delaware corporation and the other parties named therein dated as of February 10, 2017 (the “Merger Agreement”).
Upon the Closing of the Merger Agreement (“Closing”), KeyStone became a wholly-owned subsidiary of the Company. As part of the merger consideration therefor, among other things, the Registered Holder received this Warrant in
exchange for a warrant to purchase shares of the common stock of KeyStone, originally issued to the Registered Holder on January 25, 2017. As of the Closing, this Warrant and the Warrant Stock are registered with the U.S. Securities and
Exchange Commission (the “SEC”) on a Registration Statement on Form S-4 (the “Registration Statement”), which became effective as of [●], 2017; however, this
registration will be subject at all times to the continued effectiveness of such Registration Statement. Terms used but not otherwise defined herein shall have the meanings ascribed to them in the Merger Agreement.  

1.    Number of Shares. Subject to the terms and conditions hereinafter set forth, the Registered
Holder is entitled, upon surrender of this Warrant, to purchase from the Company an aggregate of 105,207 shares of Warrant Stock (subject to adjustment as provided herein). 

2.    Exercise. 

(a)    This Warrant may be exercised by the Registered Holder, in whole or in part, by surrendering this Warrant, with the
purchase/exercise form appended hereto as Exhibit A (the “Exercise Notice”) duly executed by such Registered Holder, at the principal office of the Company, or at such other office or agency as the Company
may designate, accompanied by payment in full of the aggregate Exercise Price payable in respect of the number of shares of Warrant Stock purchased upon such exercise. The Exercise Price may be paid by cash, check wire or transfer of immediately
available funds, or by the surrender of promissory notes or other instruments representing indebtedness of the Company to the Registered Holder. 

(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 this Warrant shall have been surrendered to the Company as provided in Section 2(a) above. 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 2(d) below shall be deemed to have become the
holder or holders of record of the Warrant Stock to be represented by such certificates. 
 (c)    Net Issue
Exercise. Notwithstanding anything contained herein to the contrary, if at any time there is not a current, valid and effective registration statement covering the issuance of the Warrant Stock that is the subject of the Exercise
Notice, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Exercise Price, elect instead to
receive upon such exercise the “Net Number” of shares of Warrant Stock determined according to the following formula (a “Cashless Exercise”): 
  

	
	
                   
 Net Number = (A × B) - (A × C)

	
                   
                                      D

	
	
                   
 For purposes of the foregoing formula:

			
		
	 A    =    
	 	the total number of shares of Warrant Stock.
		
	 B    =    
	 	the arithmetic average of the Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the Exercise Notice.
		
	 C    =    
	 	the Exercise Price then in effect for the applicable Warrant Stock at the time of such exercise.
		
	 D    =    
	 	the Closing Sale Price of the Common Stock on the date of the Exercise Notice.

 If Warrant Stock is issued pursuant to such a Cashless Exercise, the parties acknowledge and agree that in
accordance with Section 3(a)(9) of the Securities Act, the Warrant Stock shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 1(d), subject to any
change in applicable law, regulation or guidance. 
 (d)    Delivery to Registered Holder. As soon
as practicable after the exercise of this Warrant in whole or in part, and in any event within ten days thereafter, the Company at its expense will cause to be issued in the name of, and delivered to, the Registered Holder: 

(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 (dated the date hereof) of
like tenor and with the same date, calling in the aggregate on the face or faces thereof for the number of shares of Warrant Stock equal (without 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 purchased by the Registered Holder upon such exercise as provided in Section 2(a) or 2(c) above (without giving effect to any adjustment thereto). 

  
 - 2 - 

 (e) Investment Representation Statement. Unless the rights under this
Warrant are exercised pursuant to an effective registration statement under the Securities Act that includes the Warrant Stock with respect to which the Warrant was exercised, it shall be a condition to any exercise of the rights under this Warrant
that the Registered Holder shall have confirmed to the satisfaction of the Company in writing, that the Warrant Stock so purchased is being acquired solely for the Registered Holder’s own account and not as a nominee for any other party, for
investment and not with a view toward distribution or resale and that the Registered Holder shall have confirmed such other matters related thereto as may be reasonably requested by the Company. 

3.    Adjustments. 

(a)    Stock Splits and Dividends. If outstanding shares of the Company’s Common Stock shall be
subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Exercise Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with
the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Exercise Price in effect immediately
prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Exercise Price, the number of shares of Warrant Stock purchasable upon the
exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Exercise Price in
effect immediately prior to such adjustment, by (ii) the Exercise Price in effect immediately after such adjustment. 

(b)    Reclassification, Etc. In case there occurs any reclassification or change of the outstanding
securities of the Company (or any other corporation the stock or securities of which are at the time receivable upon the exercise of this Warrant) or any similar corporate reorganization on or after the date hereof, then and in each such case the
Registered Holder, upon the exercise hereof at any time after the consummation of such reclassification, change, or reorganization shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise
hereof prior to such consummation, the stock or other securities or property to which such Registered Holder would have been entitled upon such consummation if such Registered Holder had exercised this Warrant immediately prior thereto, all subject
to further adjustment pursuant to the provisions of this Section 3. 
 (c)    Adjustment
Certificate. When any adjustment is required to be made in the Warrant Stock or the Exercise Price pursuant to this Section 3, the Company shall promptly mail to the Registered Holder a certificate setting forth (i) a brief
statement of the facts requiring such adjustment, (ii) the Exercise Price after such adjustment and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment. 

  
 - 3 - 

 (d)    Acknowledgement. In order to avoid doubt, it is
acknowledged that the holder of this Warrant shall be entitled to the benefit of all adjustments pursuant to this Section 3 which occur prior to the exercise of this Warrant. 

4.    Transfers. 

(a)    Transferability. The Registered Holder may not assign, pledge, or otherwise transfer this
Warrant, in whole or in part without the Company’s prior written consent. The Registered Holder further agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Warrant Stock, or any beneficial
interest therein, without the Company’s prior written consent. 
 (b)    Instructions Regarding Transfer
Restrictions. The Registered Holder consents to the Company making a notation on its records and giving instructions to any transfer agent in order to implement the restrictions on transfer established in this
Section 4. 
 (c)    Taxes.     In no event shall the
Company be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Registered Holder, and the Company shall not be required to issue or deliver
any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or is not
payable. 
 5.    Other Representations of Registered Holder. With respect to this Warrant,
Registered Holder represents and warrants to the Company as follows: 
 (a)    Experience. It is
experienced in evaluating and investing in companies engaged in businesses similar to that of the Company; it understands that acquisition of this Warrant and investment in the Warrant Stock involves substantial risks; it has made detailed inquiries
concerning the Company, its business and services, its officers and its personnel; the officers of the Company have made available to Registered Holder any and all written information it has requested; the officers of the Company have answered to
Registered Holder’s satisfaction all inquiries made by it; it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of investment in the Company; it can afford to bear the
economic risk of holding the Warrant and Warrant Stock for an indefinite period of time and has adequate means for providing for its current needs and contingencies; and can afford to suffer a complete loss of its investment in the Warrant and
Warrant Stock. 
 (b)    Investment. It is acquiring this Warrant and the Warrant Stock for
investment for its own account and not with a view to, or for resale in connection with, any distribution thereof. The Registered Holder has no present intention of selling, granting any participation in, or otherwise distributing the Warrant Stock,
nor does it have any contract, undertaking, agreement or arrangement for the same. 
 (c)    Restrictions on
Resales. It acknowledges that, to the extent that at any time the offer and sale of the Warrant Stock is not registered on a then currently effective registration statement with the SEC, the Warrant Stock must be held indefinitely
unless the 

  
 - 4 - 

 
resale of such Warrant Stock is subsequently registered on an effective registration statement with the SEC under the Securities Act, or an exemption from such registration requirements is
available for such resale. The Registered Holder is aware of the provisions of Rule 144 promulgated under the Securities Act, which permits the resale of restricted securities subject to the satisfaction of certain conditions, which may
include, among other things, the availability of certain current public information about the Company; the resale occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being
sold during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s transaction,” a transaction directly with a “market maker” or a “riskless principal transaction”
(as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder); the filing of a Form 144 notice, if applicable; and analyses relating to whether the Company
was ever a “shell company” as referred to in Rule 144(i) . The Registered Holder acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time the Registered
Holder wishes to sell the Warrant Stock and that, in such event, the Registered Holder may be precluded from selling the Warrant Stock under Rule 144 even if the other applicable requirements of Rule 144 and this Warrant have been
satisfied. The Registered Holder acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Warrant
Stock. The Registered Holder understands that, although Rule 144 is not an exclusive safe harbor, the SEC has expressed its opinion that persons proposing to sell restricted securities other than in a registered offering or pursuant to
Rule 144 will have a substantial burden of proof in establishing that an exemption from the applicable registration requirements is available for such offers or sales and that such persons and the brokers who participate in the transactions do
so at their own risk. 
 (d)    Access to Data. It has had an opportunity to discuss the
Company’s business, management and financial affairs with the Company’s management and has had the opportunity to inspect the Company’s facilities. 

(e)    Accredited Investor. It is an “accredited investor” within the meaning of Regulation
D promulgated under the Securities Act and agrees to submit to the Company such further assurances of such status as may be reasonably requested by the Company. 

(f)     No “Bad Actor” Disqualification. Neither (i) the Registered Holder, (ii) any of
its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members, nor (iii) any beneficial owner of any of the Company’s voting equity
securities (in accordance with Rule 506(d) of the Securities Act) held by the Registered Holder is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii) under the Securities Act, except as
set forth in Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed, reasonably in advance of the acceptance of this Warrant, in writing in reasonable detail to the Company. 

6.    Lock-Up Agreement. In connection with any public
offering of the Company’s securities and upon request of the Company or the underwriters managing such offering of the Company’s securities, the Registered Holder agrees not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities (other than those 

  
 - 5 - 

 
included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days but subject to such
extension or extensions as may be required by the underwriters in order to publish research reports while complying with Rule 2711 of the National Association of Security Dealers, Inc. and Rule 472(f)(4) of the New York Stock Exchange) from the
effective date of such registration statement as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the Company’s initial
public offering. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect 

7.    No Impairment. The Company will not, by amendment of its charter 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 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 holder of this Warrant against impairment. When issued in accordance with the terms hereof against payment in full of the aggregate
Exercise Price therefor, the Warrant Stock will duly and validly issued, fully paid and will be free and clear of all liens, claims and encumbrances except as set forth in the Company’s Stockholders’ Agreement and such other liens, claims
and encumbrances as may be created by the holder of the Warrant. 
 8.    Termination. This Warrant
(and the right to purchase Warrant Stock upon exercise hereof) shall terminate on January 25, 2022 (the “Expiration Date”). 

9.    Notices of Certain Transactions. In case: 

(a)    the Company shall set a record date for the holders of its Common 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, 

(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, 
 (c)    of any other event which would constitute a Termination Event, 

(d)    of the voluntary or involuntary dissolution, liquidation or winding-up of
the Company, or 
 (e)    of any redemption of the Common Stock (or other stock or securities at the time deliverable
upon the exercise of this Warrant), 

  
 - 6 - 

 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 record date 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, redemption, conversion or other Termination Event is to take place, and the time, if any
is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up, redemption or conversion) are to be determined. Such notice shall be mailed at least ten days prior to the record date or effective date for the event specified in such notice. 

10.    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. 

11.    No Rights as Stockholder. Nothing contained herein shall entitle the Registered Holder to any
rights as a stockholder of the Company or to be deemed the holder of any securities that may at any time be issuable on the exercise of the rights hereunder for any purpose nor shall anything contained herein be construed to confer upon the
Registered Holder, as such, any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of
stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or any other rights of a
stockholder of the Company until the rights under the Warrant shall have been exercised and the securities purchasable upon exercise of the rights hereunder shall have become deliverable as provided herein. 

12.    No Fractional Shares. No fractional shares of Common Stock (or other stock or securities at
the time deliverable upon the exercise of this Warrant) will be issued in connection with any exercise hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall round up and deliver any such fractional share to
the nearest whole share. 
 13.    Change of Control. In the event of a Change of Control of the Company,
if the shares of Common Stock of the Company become convertible or exchangeable for the shares of Common Stock of another company (the “Change of Control Company”), whether by virtue of the Change of Control Company being the
merged, consolidated, surviving, controlling or other entity in a transaction constituting a Change of Control, then this Warrant shall be converted into and exchangeable for a warrant to purchase shares of the common stock of the Change of Control
Company; provided, further, that price per share of common stock of the Change of Control Company purchasable pursuant to this section will be calculated based upon the following formula: the numerator shall be the Exercise Price and the
denominator shall be the number of shares for which each share of the Company is exchanged or, at the option of the 

  
 - 7 - 

 
Registered Holder, in accordance with Section 2.c above. It shall be the obligation of the Company to assure and effectuate the foregoing, to advise all parties to the Change of Control of this
obligation and the rights of the Registered Holder hereunder, and to obtain the written assumption by the Change of Control Company of this Warrant and the obligations of the Company hereunder and to provide a copy thereof to the Registered Holder.

merger, consolidation or statutory share exchange in which (1) the Company is a constituent party or (2) a subsidiary of the Company is a constituent party and the Company issues capital shares pursuant to such merger or consolidation,
pursuant to which the equityholders of the Company as constituted immediately prior to such transaction will not own a majority, by voting power, of the capital shares of (x) the surviving or resulting entity or (y) if the surviving or
resulting entity is a wholly owned subsidiary of another entity immediately following such merger or consolidation, the parent corporation of such surviving or resulting entity;

all of the assets of the Company and its subsidiaries, taken as a whole, are held by such subsidiary or subsidiaries, except where such sale, exchange, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of such
Person; or 
 (c)     a transaction or series of transactions pursuant to which any Person(s) acting together becomes
the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, as amended, or any successor provisions thereto),
directly or indirectly, of more than fifty percent (50%) of the Common Stock of the Company. 
 14.
    Miscellaneous.

required or permitted pursuant to this Warrant shall be in writing and shall be deemed sufficient upon receipt, when delivered personally or sent by courier, overnight delivery service or confirmed facsimile, or forty-eight hours after being

 NOVUME SOLUTIONS, INC. 

Common Stock Purchase Warrant 

Novume Solutions, Inc., a Delaware corporation (the “Company”), for value received, hereby certifies that
                     (the “Registered Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at
any time after the date hereof and on or before the Expiration Date (as defined in Section 8 below) shares of the Company’s Common Stock, par value $0.0001 per share (“Common Stock”), at an exercise price per share (the
“Exercise Price”) equal to $3.61. The shares of Common Stock issuable upon exercise of this Common Stock Purchase Warrant (the “Warrant”) are referred to hereinafter as the “Warrant Stock”. 

This Warrant is issued to the Registered Holder pursuant to and is subject to the terms and conditions of the Merger Agreement by and among
the Company, KeyStone Solutions, Inc., a Delaware corporation (“KeyStone”), Brekford Corp., a Delaware corporation and the other parties named therein dated as of February 10, 2017 (the “Merger Agreement”).
Upon the Closing of the Merger Agreement (“Closing”), KeyStone became a wholly-owned subsidiary of the Company. As part of the merger consideration therefor, among other things, the Registered Holder received this Warrant in
exchange for a warrant to purchase shares of the common stock of KeyStone, originally issued to the Registered Holder on January 25, 2017. As of the Closing, this Warrant and the Warrant Stock are registered with the U.S. Securities and
Exchange Commission (the “SEC”) on a Registration Statement on Form S-4 (the “Registration Statement”), which became effective as of [●], 2017; however, this
registration will be subject at all times to the continued effectiveness of such Registration Statement. Terms used but not otherwise defined herein shall have the meanings ascribed to them in the Merger Agreement.  

1.    Number of Shares. Subject to the terms and conditions hereinafter set forth, the Registered
Holder is entitled, upon surrender of this Warrant, to purchase from the Company an aggregate of 105,207 shares of Warrant Stock (subject to adjustment as provided herein). 

2.    Exercise. 

(a)    This Warrant may be exercised by the Registered Holder, in whole or in part, by surrendering this Warrant, with the
purchase/exercise form appended hereto as Exhibit A (the “Exercise Notice”) duly executed by such Registered Holder, at the principal office of the Company, or at such other office or agency as the Company
may designate, accompanied by payment in full of the aggregate Exercise Price payable in respect of the number of shares of Warrant Stock purchased upon such exercise. The Exercise Price may be paid by cash, check wire or transfer of immediately
available funds, or by the surrender of promissory notes or other instruments representing indebtedness of the Company to the Registered Holder. 

(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 this Warrant shall have been surrendered to the Company as provided in Section 2(a) above. 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 2(d) below shall be deemed to have become the
holder or holders of record of the Warrant Stock to be represented by such certificates. 
 (c)    Net Issue
Exercise. Notwithstanding anything contained herein to the contrary, if at any time there is not a current, valid and effective registration statement covering the issuance of the Warrant Stock that is the subject of the Exercise
Notice, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Exercise Price, elect instead to
receive upon such exercise the “Net Number” of shares of Warrant Stock determined according to the following formula (a “Cashless Exercise”): 
  

			
		 	 Net Number = (A × B) - (A × C)

		 	              D

		
		 	 For purposes of the foregoing formula:

		
	A=	 	the total number of shares of Warrant Stock.
		
	B=	 	the arithmetic average of the Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the Exercise Notice.
		
	C=	 	the Exercise Price then in effect for the applicable Warrant Stock at the time of such exercise.
		
	D=	 	the Closing Sale Price of the Common Stock on the date of the Exercise Notice.

 If Warrant Stock is issued pursuant to such a Cashless Exercise, the parties acknowledge and agree that in
accordance with Section 3(a)(9) of the Securities Act, the Warrant Stock shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 1(d), subject to any
change in applicable law, regulation or guidance. 
 (d)    Delivery to Registered Holder. As soon
as practicable after the exercise of this Warrant in whole or in part, and in any event within ten days thereafter, the Company at its expense will cause to be issued in the name of, and delivered to, the Registered Holder: 

(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 (dated the date hereof) of
like tenor and with the same date, calling in the aggregate on the face or faces thereof for the number of shares of Warrant Stock equal (without 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 purchased by the Registered Holder upon such exercise as provided in Section 2(a) or 2(c) above (without giving effect to any adjustment thereto). 

  
 - 2 - 

 (e) Investment Representation Statement. Unless the rights under this
Warrant are exercised pursuant to an effective registration statement under the Securities Act that includes the Warrant Stock with respect to which the Warrant was exercised, it shall be a condition to any exercise of the rights under this Warrant
that the Registered Holder shall have confirmed to the satisfaction of the Company in writing, that the Warrant Stock so purchased is being acquired solely for the Registered Holder’s own account and not as a nominee for any other party, for
investment and not with a view toward distribution or resale and that the Registered Holder shall have confirmed such other matters related thereto as may be reasonably requested by the Company. 

3.    Adjustments. 

(a)    Stock Splits and Dividends. If outstanding shares of the Company’s Common Stock shall be
subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Exercise Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with
the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Exercise Price in effect immediately
prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Exercise Price, the number of shares of Warrant Stock purchasable upon the
exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Exercise Price in
effect immediately prior to such adjustment, by (ii) the Exercise Price in effect immediately after such adjustment. 

(b)    Reclassification, Etc. In case there occurs any reclassification or change of the outstanding
securities of the Company (or any other corporation the stock or securities of which are at the time receivable upon the exercise of this Warrant) or any similar corporate reorganization on or after the date hereof, then and in each such case the
Registered Holder, upon the exercise hereof at any time after the consummation of such reclassification, change, or reorganization shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise
hereof prior to such consummation, the stock or other securities or property to which such Registered Holder would have been entitled upon such consummation if such Registered Holder had exercised this Warrant immediately prior thereto, all subject
to further adjustment pursuant to the provisions of this Section 3. 
 (c)    Adjustment
Certificate. When any adjustment is required to be made in the Warrant Stock or the Exercise Price pursuant to this Section 3, the Company shall promptly mail to the Registered Holder a certificate setting forth (i) a brief
statement of the facts requiring such adjustment, (ii) the Exercise Price after such adjustment and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment. 

  
 - 3 - 

 (d)    Acknowledgement. In order to avoid doubt, it is
acknowledged that the holder of this Warrant shall be entitled to the benefit of all adjustments pursuant to this Section 3 which occur prior to the exercise of this Warrant. 

4.    Transfers. 

(a)    Transferability. The Registered Holder may not assign, pledge, or otherwise transfer this
Warrant, in whole or in part without the Company’s prior written consent. The Registered Holder further agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Warrant Stock, or any beneficial
interest therein, without the Company’s prior written consent. 
 (b)    Instructions Regarding Transfer
Restrictions. The Registered Holder consents to the Company making a notation on its records and giving instructions to any transfer agent in order to implement the restrictions on transfer established in this
Section 4. 
 (c)    Taxes.     In no event shall the
Company be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Registered Holder, and the Company shall not be required to issue or deliver
any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or is not
payable. 
 5.    Other Representations of Registered Holder. With respect to this Warrant,
Registered Holder represents and warrants to the Company as follows: 
 (a)    Experience. It is
experienced in evaluating and investing in companies engaged in businesses similar to that of the Company; it understands that acquisition of this Warrant and investment in the Warrant Stock involves substantial risks; it has made detailed inquiries
concerning the Company, its business and services, its officers and its personnel; the officers of the Company have made available to Registered Holder any and all written information it has requested; the officers of the Company have answered to
Registered Holder’s satisfaction all inquiries made by it; it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of investment in the Company; it can afford to bear the
economic risk of holding the Warrant and Warrant Stock for an indefinite period of time and has adequate means for providing for its current needs and contingencies; and can afford to suffer a complete loss of its investment in the Warrant and
Warrant Stock. 
 (b)    Investment. It is acquiring this Warrant and the Warrant Stock for
investment for its own account and not with a view to, or for resale in connection with, any distribution thereof. The Registered Holder has no present intention of selling, granting any participation in, or otherwise distributing the Warrant Stock,
nor does it have any contract, undertaking, agreement or arrangement for the same. 
 (c)    Restrictions on
Resales. It acknowledges that, to the extent that at any time the offer and sale of the Warrant Stock is not registered on a then currently effective registration statement with the SEC, the Warrant Stock must be held indefinitely
unless the 

  
 - 4 - 

 
resale of such Warrant Stock is subsequently registered on an effective registration statement with the SEC under the Securities Act, or an exemption from such registration requirements is
available for such resale. The Registered Holder is aware of the provisions of Rule 144 promulgated under the Securities Act, which permits the resale of restricted securities subject to the satisfaction of certain conditions, which may
include, among other things, the availability of certain current public information about the Company; the resale occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being
sold during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s transaction,” a transaction directly with a “market maker” or a “riskless principal transaction”
(as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder); the filing of a Form 144 notice, if applicable; and analyses relating to whether the Company
was ever a “shell company” as referred to in Rule 144(i) . The Registered Holder acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time the Registered
Holder wishes to sell the Warrant Stock and that, in such event, the Registered Holder may be precluded from selling the Warrant Stock under Rule 144 even if the other applicable requirements of Rule 144 and this Warrant have been
satisfied. The Registered Holder acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Warrant
Stock. The Registered Holder understands that, although Rule 144 is not an exclusive safe harbor, the SEC has expressed its opinion that persons proposing to sell restricted securities other than in a registered offering or pursuant to
Rule 144 will have a substantial burden of proof in establishing that an exemption from the applicable registration requirements is available for such offers or sales and that such persons and the brokers who participate in the transactions do
so at their own risk. 
 (d)    Access to Data. It has had an opportunity to discuss the
Company’s business, management and financial affairs with the Company’s management and has had the opportunity to inspect the Company’s facilities. 

(e)    Accredited Investor. It is an “accredited investor” within the meaning of Regulation
D promulgated under the Securities Act and agrees to submit to the Company such further assurances of such status as may be reasonably requested by the Company. 

(f)     No “Bad Actor” Disqualification. Neither (i) the Registered Holder, (ii) any of
its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members, nor (iii) any beneficial owner of any of the Company’s voting equity
securities (in accordance with Rule 506(d) of the Securities Act) held by the Registered Holder is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii) under the Securities Act, except as
set forth in Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed, reasonably in advance of the acceptance of this Warrant, in writing in reasonable detail to the Company. 

6.    Lock-Up Agreement. In connection with any public
offering of the Company’s securities and upon request of the Company or the underwriters managing such offering of the Company’s securities, the Registered Holder agrees not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities (other than those 

  
 - 5 - 

 
included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days but subject to such
extension or extensions as may be required by the underwriters in order to publish research reports while complying with Rule 2711 of the National Association of Security Dealers, Inc. and Rule 472(f)(4) of the New York Stock Exchange) from the
effective date of such registration statement as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the Company’s initial
public offering. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect 

7.    No Impairment. The Company will not, by amendment of its charter 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 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 holder of this Warrant against impairment. When issued in accordance with the terms hereof against payment in full of the aggregate
Exercise Price therefor, the Warrant Stock will duly and validly issued, fully paid and will be free and clear of all liens, claims and encumbrances except as set forth in the Company’s Stockholders’ Agreement and such other liens, claims
and encumbrances as may be created by the holder of the Warrant. 
 8.    Termination. This Warrant
(and the right to purchase Warrant Stock upon exercise hereof) shall terminate on January 25, 2022 (the “Expiration Date”). 

9.    Notices of Certain Transactions. In case: 

(a)    the Company shall set a record date for the holders of its Common 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, 

(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, 
 (c)    of any other event which would constitute a Termination Event, 

(d)    of the voluntary or involuntary dissolution, liquidation or winding-up of
the Company, or 
 (e)    of any redemption of the Common Stock (or other stock or securities at the time deliverable
upon the exercise of this Warrant), 

  
 - 6 - 

 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 record date 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, redemption, conversion or other Termination Event is to take place, and the time, if any
is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up, redemption or conversion) are to be determined. Such notice shall be mailed at least ten days prior to the record date or effective date for the event specified in such notice. 

10.    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. 

11.    No Rights as Stockholder. Nothing contained herein shall entitle the Registered Holder to any
rights as a stockholder of the Company or to be deemed the holder of any securities that may at any time be issuable on the exercise of the rights hereunder for any purpose nor shall anything contained herein be construed to confer upon the
Registered Holder, as such, any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of
stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or any other rights of a
stockholder of the Company until the rights under the Warrant shall have been exercised and the securities purchasable upon exercise of the rights hereunder shall have become deliverable as provided herein. 

12.    No Fractional Shares. No fractional shares of Common Stock (or other stock or securities at
the time deliverable upon the exercise of this Warrant) will be issued in connection with any exercise hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall round up and deliver any such fractional share to
the nearest whole share. 
 13.    Change of Control. In the event of a Change of Control of the Company,
if the shares of Common Stock of the Company become convertible or exchangeable for the shares of Common Stock of another company (the “Change of Control Company”), whether by virtue of the Change of Control Company being the
merged, consolidated, surviving, controlling or other entity in a transaction constituting a Change of Control, then this Warrant shall be converted into and exchangeable for a warrant to purchase shares of the common stock of the Change of Control
Company; provided, further, that price per share of common stock of the Change of Control Company purchasable pursuant to this section will be calculated based upon the following formula: the numerator shall be the Exercise Price and the
denominator shall be the number of shares for which each share of the Company is exchanged or, at the option of the 

  
 - 7 - 

 
Registered Holder, in accordance with Section 2.c above. It shall be the obligation of the Company to assure and effectuate the foregoing, to advise all parties to the Change of Control of this
obligation and the rights of the Registered Holder hereunder, and to obtain the written assumption by the Change of Control Company of this Warrant and the obligations of the Company hereunder and to provide a copy thereof to the Registered Holder.

merger, consolidation or statutory share exchange in which (1) the Company is a constituent party or (2) a subsidiary of the Company is a constituent party and the Company issues capital shares pursuant to such merger or consolidation,

resulting entity is a wholly owned subsidiary of another entity immediately following such merger or consolidation, the parent corporation of such surviving or resulting entity;

all of the assets of the Company and its subsidiaries, taken as a whole, are held by such subsidiary or subsidiaries, except where such sale, exchange, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of such
Person; or 
 (c)     a transaction or series of transactions pursuant to which any Person(s) acting together becomes
the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, as amended, or any successor provisions thereto),
directly or indirectly, of more than fifty percent (50%) of the Common Stock of the Company. 
 14.
    Miscellaneous. 
 (a)     Mailing of Notices. Any notice
required or permitted pursuant to this Warrant shall be in writing and shall be deemed sufficient upon receipt, when delivered personally or sent by courier, overnight delivery service or confirmed facsimile, or forty-eight hours after being
