 Warrant Price: $1.077494, subject to adjustment

	Credit Facility:	 	This Warrant is issued in connection with that certain Loan and Security Agreement of even date herewith between Silicon Valley Bank and the Company.

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, SILICON VALLEY BANK (Silicon Valley Bank, together with any successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, is referred to hereinafter as “Holder”) is
entitled to purchase the number of fully paid and non-assessable shares (the “Shares”) of the above-stated class of stock (the “Class”) of the above-named company (the “Company”) at the above-stated Warrant Price per
Share, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 
 ARTICLE 1. EXERCISE. 
 1.1 Method of Exercise. Holder may exercise
this Warrant by delivering the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set
forth in Article 1.2, Holder shall also deliver to the Company a check, wire transfer (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

 1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1, Holder may from time to time
convert this Warrant, in whole or in part, into a number of Shares as is computed using the following formula: 
  

			
	X =	 	Y(A-B)
		 	(A)








 where: 

			
		
	 X =
	  	the number of shares of the Class to be issued to the Holder pursuant to this Article 1.2.
		
	 Y =
	  	the number of shares of the Class covered by this Warrant in respect of which the net issue election is made pursuant to this Article 1.2.
		
	 A =
	  	the Fair Market Value (as determined pursuant to Article 1.3) of one share of the Class, as determined at the time the net issue election is made pursuant to this Article
1.2.
		
	 B =
	  	the Warrant Price in effect under this Warrant at the time the net issue election is made pursuant to this Article 1.2.


 1.3 Fair Market Value. If, at the time of any exercise or conversion of this Warrant, the
Company’s common stock is traded in a public market and the Shares are common stock, the fair market value of a Share shall be the closing price of a share of common stock reported for the business day immediately before the day Holder delivers
this Warrant together with its Notice of Exercise to the Company (or in the instance where the Warrant is exercised immediately prior to the effectiveness of the Company’s registration statement filed with the Securities and Exchange Commission
in connection with the Company’s initial offering and sale of its shares to the public (“IPO”), the “price to public” per share price specified in the final prospectus relating to the IPO). If the Company’s common stock
is traded in a public market and the Shares are preferred stock, the fair market value of a Share shall be the closing price of a share of the Company’s common stock reported for the business day immediately before the day Holder delivers this
Warrant together with its Notice of Exercise to the Company (or, in the instance where the Warrant is exercised immediately prior to the effectiveness of the IPO, the initial “price to public” per share price specified in the final
prospectus relating to such offering), in both cases, multiplied by the number of shares of the Company’s common stock into which a Share is convertible. If the Company’s common stock is not traded in a public market, the Board of
Directors of the Company shall determine the fair market value of each Share in its reasonable good faith judgment. 
 1.4
Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant and, if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares
acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new warrant of like tenor representing the Shares not so acquired. 
 1.5 Replacement of Warrants. On 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, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor.

 1.6 Treatment of Warrant Upon Acquisition of Company. 

1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale, transfer, exclusive
license, or other disposition of all or substantially all of the assets of the Company, or any reorganization, consolidation, merger or sale of outstanding equity securities of the Company where the holders of the Company’s outstanding voting
equity securities as of immediately before the transaction beneficially own less than a majority of the outstanding voting equity securities of the surviving or successor entity as of immediately after the transaction. 

1.6.2 Treatment of Warrant at Acquisition. 
 A) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition in which the sole consideration is cash, either (a) Holder shall exercise its conversion or purchase
right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of such
Acquisition. The Company shall provide the Holder with written notice of its request relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such
notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition. 
 B) Upon the
closing of any Acquisition other than those particularly described in subsection (A) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Shares shall be
adjusted accordingly. 
 1.7 Stockholders’ Agreement. Upon any exercise or conversion of this Warrant, Holder shall
at the Company’s request become a party to, by execution and delivery to the Company of a counterpart signature page, joinder agreement, instrument of accession or the like, the Company’s stockholders’ agreement, solely with respect
to the Shares issued upon such exercise or conversion, solely to the extent that all holders of outstanding shares of the Class are then parties thereto, and solely to the extent that such agreement is then by its terms in force and effect.

 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 
 2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the outstanding shares of the Class payable in common stock or other securities, then upon exercise of this Warrant,
for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend occurred, if the Company
subdivides the outstanding shares of the Class by reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased.
If the outstanding shares of the Class are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased.

 2.2 Reclassification, Exchange, Combinations or Substitution. Subject to Article 1.6
above, upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. Such an
event shall include, without limitation, any automatic conversion of the outstanding or issuable securities of the Company of the same class or series as the Shares to common stock pursuant to the terms of the Company’s Amended and Restated
Certificate of Incorporation (as amended and in effect from time to time, the “Charter”), including, without limitation, upon consummation of the IPO. The Company or its successor shall promptly issue to Holder a certificate pursuant to
Article 2.6 hereof setting forth the number, class and series or other designation of such new securities or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution or other
event that results in a change of the number and/or class of securities issuable upon the exercise or conversion of this Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or
other events. 
 2.3 Adjustments for Diluting Issuances. The number of shares of common stock issuable upon conversion of
the Shares shall be subject to adjustment, from time to time in the manner set forth in the Charter as if the Shares were issued and outstanding on and as of the date of any such required adjustment. The provisions set forth for the Class in the
Charter relating to the above in effect as of the Issue Date may not be amended, modified or waived, without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with the Shares in the same
manner as such amendment, modification or waiver affects the rights associated with all other shares of the Class. 
 2.4 No
Impairment. The Company shall not, by amendment of the Charter or through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article 2 and in taking all such action as may be necessary
or appropriate to protect Holder’s rights under this Article against impairment. 
 2.5 Fractional Shares. No
fractional Shares shall be issuable upon exercise or conversion of the Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the
Warrant, the Company shall eliminate such fractional share interest by paying Holder in cash the amount computed by multiplying the fractional interest by the fair market value of a full Share. 

2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the Company shall
promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate of 

  
 4 








 
its Chief Financial Officer or other duly authorized officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish
Holder a certificate setting forth the Warrant Price, Class and number of Shares in effect upon the date thereof and the series of adjustments leading to such Warrant Price, Class and number of Shares. 

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 
 3.1 Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder as follows: 
 (a) The initial Warrant Price referenced on the first page of this Warrant is not greater than the price per share at which shares of the Class were last issued in an arms-length transaction in which at
least $500,000 of such shares were sold. 
 (b) All Shares which may be issued upon the exercise of the purchase right
represented by this Warrant, and all securities, if any, issuable upon conversion of the Shares, shall, upon issuance in accordance with the terms hereof, be duly authorized, validly issued, fully paid and non-assessable, and free of any liens and
encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. 

(c) The Company’s summary capitalization table attached hereto as Schedule 1 is true and complete as of the Issue Date.

 3.2 Notice of Certain Events. If the Company proposes at any time (a) to declare any dividend or distribution
upon the outstanding shares of the Class, whether in cash, property, stock, or other securities and whether or not a regular cash dividend (other than securities for which adjustment is made pursuant to Article 2 hereof); (b) to offer for
subscription or sale pro rata to the holders of the outstanding shares of the Class any additional shares of any class or series of the Company’s stock; (c) to effect any reclassification, reorganization or recapitalization of the shares
of the Class; or (d) to effect an Acquisition or to liquidate, dissolve or wind up; then, in connection with each such event, the Company shall give Holder: (1) at least 10 days prior written notice of the date on which a record will be
taken for such dividend, distribution, or subscription rights (and specifying the date on which the holders of shares of the Class will be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in
(c) and (d) above; and (2) in the case of the matters referred to in (c) and (d) above at least 10 days prior written notice of the date when the same will take place (and specifying the date on which the holders of shares
of the Class will be entitled to exchange their shares for the securities or other property deliverable upon the occurrence of such event). 
 3.3 Registration Under Securities Act of 1933, as amended. The Company agrees that the Shares or, if the Shares are convertible into common stock of the Company, such common stock, shall have
certain incidental, or “Piggyback,” and S-3 registration rights as if Holder were a party to the Company’s Second Amended and Restated Investor’s Rights Agreement dated as of December 29, 2003 (as amended and in effect from
time to time, the “Rights Agreement”) with respect to those sections of the Rights Agreement. The provisions set forth in the Rights Agreement relating to the above in effect as of the Issue Date may not be


  
 5 








 
amended, modified or waived without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with the Shares in the same manner as such
amendment, modification, or waiver affects the rights associated with all other shares of the Class whose holders are parties thereto. In addition, Holder agrees to be bound by the “Lock-Up” provision of which the holders of the
outstanding shares of the Class (or common stock issuable on conversion thereof) are bound pursuant to the Company’s Investor’s Rights Agreement. 
 3.4 No Stockholder Rights. Without limiting any provision in this Warrant, Holder agrees that it will not have any rights as a stockholder of the Company until the exercise of this Warrant.

 3.5 Certain Information. The Company agrees to provide Holder at any time and from time to time with such information
as Holder may reasonably request for purposes of Holder’s compliance with regulatory, accounting and reporting requirements applicable to Holder. 
 ARTICLE 4. REPRESENTATIONS. WARRANTIES OF THE HOLDER. The Holder represents and warrants to the Company as follows: 
 4.1 Purchase for Own Account. This Warrant and the securities to be acquired upon exercise of this Warrant by Holder will be acquired for investment for Holder’s account, not as a nominee or

4.2 Disclosure of Information. Holder has received or has had full access to all the information it considers necessary or
appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to Holder or to which Holder has access. 
 4.3 Investment Experience. Holder understands that the
purchase of this Warrant and its underlying securities involves substantial risk. Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s

and/or has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial
circumstances of such persons.

meaning of Regulation D promulgated under the Act. 

  
 6 








 4.5 The Act. Holder understands that this Warrant and the Shares issuable upon
exercise or conversion hereof have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein.
Holder understands that this Warrant and the Shares issued upon any exercise or conversion hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from
such registration and qualification are otherwise available.
