purchase/exercise form appended hereto as Exhibit A 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, accompanied by payment in full of the Purchase Price payable in respect of the number of shares of Warrant Stock purchased upon such exercise. The Purchase Price may be paid by cash, check, wire transfer 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 1(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 1(d) below shall be deemed to have become the holder or holders of record of the Warrant Stock represented by such certificates. 
  

(c) Net Issue Exercise. 
  
 (i) In lieu of exercising this Warrant in the manner provided above in Section 1(a), the Registered Holder may elect to receive shares equal to the value
of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the 

  

 1 

 
Company together with notice of such election on the purchase/exercise form appended hereto as Exhibit A duly executed by such Registered Holder or
such Registered Holder’s duly authorized attorney, in which event the Company shall issue to such Registered Holder a number of shares of Warrant Stock computed using the following formula: 
  
 X = Y (A - B)  
 A 
  

	 Where
	 	X = The number of shares of Warrant Stock to be issued to the Registered Holder.
		
	 	 	Y = The number of shares of Warrant Stock purchasable under this Warrant (at the date of such calculation).
		
	 	 	A = The fair market value of one share of Warrant Stock (at the date of such calculation).
		
	 	 	B = The Purchase Price (as adjusted to the date of such calculation).

  
 (ii) For purposes of
this Section 1(c), the fair market value of Warrant Stock on the date of calculation shall mean with respect to each share of Warrant Stock: 
  
 (A) if the exercise is in connection with an initial public offering of the Common Stock of the Company (the “Common Stock”), and if the
Company’s Registration Statement relating to such public offering has been declared effective by the Securities and Exchange Commission, then the fair market value shall be the product of (x) the initial “Price to Public” per share
specified in the final prospectus with respect to the offering and (y) the number of shares of Common Stock into which each share of Warrant Stock is convertible at the date of calculation; 
  
 (B) if this Warrant is exercised after, and not in connection with, the
Company’s initial public offering, and the Company’s Common Stock is traded on a securities exchange or The Nasdaq Stock Market or actively traded over the counter: 
  
 (1) if the Company’s Common Stock is traded on a securities exchange or The Nasdaq Stock Market, the fair market value
shall be deemed to be the product of (x) the average of the closing prices over a 30-day period ending three days before the date of calculation and (y) the number of shares of Common Stock into which each share of Warrant Stock is convertible on
such date; or 
  
 (2) if the Company’s Common Stock is
actively traded over the counter, the fair market value shall be deemed to be the product of(x) the average of the closing bid or sales price (whichever is applicable) over the 30-day period ending three days before the date of calculation and (y)
the number of shares of Common Stock into which each share of Warrant Stock is convertible on such date; or 
  
 (C) if neither (A) nor (B) is applicable, the fair market value of Warrant Stock shall be at the highest price per share which the Company could obtain
on the date of calculation from a willing buyer (not a current employee or director) for shares of 

  

 2 

 
Warrant Stock sold by the Company, from authorized but unissued shares, as determined in good faith by the Board of Directors, unless the Company is at such
time subject to an acquisition as described in Section 7(b) below, in which case the fair market value of Warrant Stock shall be deemed to be the value received by the holders of such stock pursuant to such acquisition. 
  
 (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 (10) days thereafter, the Company at its expense 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 (dated the date hereof) of like tenor, 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 1(a) or 1(c) above. 
  
 2. Adjustments. 
  
 (a) Redemption or Conversion of Preferred Stock. If all of the Preferred Stock is redeemed or converted into shares of Common Stock, then this Warrant shall automatically become exercisable for that number of shares of Common
Stock equal to the number of shares of Common Stock that would have been received if this Warrant had been exercised in full and the shares of Preferred Stock received thereupon bad been simultaneously converted into shares of Common Stock
immediately prior to such event, and the Exercise Price shall be automatically adjusted to equal the number obtained by dividing (i) the aggregate Purchase Price of the shares of Preferred Stock for which this Warrant was exercisable immediately
prior to such redemption or conversion, by (ii) the number of shares of Common Stock for which this Warrant is exercisable immediately after such redemption or conversion. 
  
 (b) Stock Splits and Dividends. If outstanding shares of the Company’s Preferred Stock shall be
subdivided into a greater number of shares or a dividend in Preferred Stock shall be paid in respect of Preferred Stock, the Purchase 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 Preferred Stock shall be combined into a smaller number of shares, the Purchase 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 Purchase Price, the number of shares of Warrant Stock purchasable
upon the exercise of this Warrant shall be changed to the number determined by dividing (1) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in
effect 

  

 3 

 
immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. 
  
 (c) Reclassification, Etc. In case there occurs any
reclassification or change of the outstanding securities of the Company or of any reorganization 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 2. 
  
 (d) Adjustment Certificate. When any adjustment is required to be made in the Warrant Stock or the Purchase Price pursuant to this Section
2, 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 Purchase 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. 
  
 (e) Acknowledgement. In order to avoid doubt, it is acknowledged that the holder of this Warrant shall be entitled to the benefit of all adjustments in the number of shares of Common Stock of the Company
issuable upon conversion of the Preferred Stock of the Company which occur prior to the exercise of this Warrant, including without limitation, any increase in the number of shares of Common Stock issuable upon conversion as a result of a dilutive
issuance of capital stock. 
  
 3. Transfers.

  
 (a) Unregistered Security. Each holder of this
Warrant acknowledges that this Warrant, the Warrant Stock and the Common Stock of the Company have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and agrees not to sell, pledge, distribute,
offer for sale, transfer or otherwise dispose of this Warrant, any Warrant Stock issued upon its exercise or any Common Stock issued upon conversion of the Warrant Stock in the absence of (i) an effective registration statement under the Securities
Act as to this Warrant, such Warrant Stock or such Common Stock and registration or qualification of this Warrant, such Warrant Stock or such Common Stock under any applicable U.S. federal or state securities law then in effect, or (ii) an exemption
from registration or qualification under the Securities Act. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect. 
  
 (b) Transferability. Subject to the provisions of Sections 3(a)
and 6 hereof, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of the Warrant with a properly executed assignment (in the form of Exhibit B hereto) at the principal office of the Company;
provided, however, that this Warrant may not be transferred in whole or in part without the prior written consent of the Company. 
  

 4 

 (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; provided, however,
that if this Warrant is properly assigned in blank, the Company may (but shall not be required to) treat the bearer hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary. 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. 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 (subject to Section 15 below) 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. 
  
 5. Representations and Warranties of the Registered Holder. The Registered Holder hereby represents and warrants to the Company that:

  
 (a) Authorization. The Registered Holder has
full power and authority to enter into this Warrant. The Warrant, when executed and delivered by the Registered Holder, will constitute a valid and legally binding obligation of the Registered Holder, enforceable in accordance with its terms, except
as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, and any other laws of general application affecting enforcement of creditors’ rights generally, and as limited by laws relating to the
availability of specific performance, injunctive relief, or other equitable remedies. 
  
 (b) Purchase Entirely for Own Account. This Warrant is issued to the Registered Holder in reliance upon the Registered Holder’s representation to the Company, which by the Registered Holder’s
acceptance of this Warrant, the Registered Holder hereby confirms, that the Warrant to be acquired by the Registered Holder, the Warrant Stock and the Common Stock to be issued upon the conversion of the Warrant Stock (collectively, the
“Securities”) will be acquired for investment for the Registered Holder’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Registered Holder has no
present intention of selling, granting any participation in, or otherwise distributing the same. By accepting this Warrant, the Registered Holder further represents that the Registered Holder does not presently have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities. The Registered Holder has not been formed for the specific purpose of acquiring the
Securities. 
  
 (c) Disclosure of Information. The
Registered Holder has had an opportunity to discuss the Company’s business, management, financial affairs and the terms and conditions of the offering of the Securities with the Company’s management and has had an opportunity to review the
Company’s facilities. The Registered Holder understands that such discussions, as well as any written information delivered by the Company to the Registered Holder, were intended to describe the aspects of the Company’s business which it
believes to be material. 
  

 5 

 (d) Restricted Securities. The Registered Holder understands that the Securities have not
been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Registered Holder’s representations as expressed herein. The Registered Holder understands that the Securities are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to
these laws, the Registered Holder must hold the Securities indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements
is available. The Registered Holder acknowledges that the Company has no obligation to register or qualify the Securities for resale, The Registered Holder further acknowledges that if an exemption front registration or qualification is available,
it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Registered Holder’s control,
and which the Company is under no obligation and may not be able to satisfy. 
  
 (e) No Public Market. The Registered Holder understands that no public market now exists for any of the securities issued by the Company, and that the Company has made no assurances that a public market
will ever exist for the Securities. 
  
 (f) Accredited or
Sophisticated Investor. The Registered Holder is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act 
  

6. Lock-up Agreement. 
  
 (a) Lock-up Period; Agreement. In connection with the initial 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 of the Company
(other than those 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) from the effective date of such registration 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. 
  
 (b) Stop-Transfer Instructions. In order to enforce the
foregoing covenants, the Company may impose stop-transfer instructions with respect to the securities of the Registered Holder (and the securities of every other person subject to the restrictions in Section 6(a)). 
  
 (c) Transferees Bound. The Registered Holder agrees that prior
to the Company’s initial public offering it will not transfer securities of the Company unless each transferee agrees in writing to be bound by all of the provisions of this Section 6.

securities upon exercise hereof) shall terminate upon the earliest to occur of the following (the “Expiration Date”): (a)

or into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company) or any other transaction or series of related transactions in which more than fifty percent (50%) of the voting power of the Company is
disposed of, provided that this Section 7 shall not apply to a merger effected exclusively for the purpose of changing the domicile of the Company or to an equity financing in which the Company is the surviving corporation, or (c) the closing of a
firm commitment underwritten public offering pursuant to a registration statement under the Securities Act 
  
 8. 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, 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 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, or
