and the Company (the “Loan Agreement”)

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, including without limitation the
mutual promises contained in the Loan Agreement, SILICON VALLEY BANK (together with any registered holder from time to time of this Warrant or any holder of the shares issuable or issued upon exercise of this Warrant, “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, 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 certified or bank check, wire transfer of same-day funds (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 determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable upon exercise of this Warrant minus
the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to Article 1.3. 







 1.3 Fair Market Value. If the Class is traded in a public market, the fair
market value of a Share shall be the average closing prices of a share of common stock reported for the three (3) business days immediately before Holder delivers this Warrant together with its Notice of Exercise to the Company. If the Class is
not traded in a public market, the Board of Directors of the Company shall determine fair market value 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 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, 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 capital stock of the Company where the
holders of the Company’s outstanding voting securities before the transaction beneficially own less than a majority of the outstanding voting securities of the surviving entity or, if applicable, its parent entity, 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 that is not a True Asset Sale (as defined below) 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 and contingent upon 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 written request of the Company, Holder agrees that, in the event of an Acquisition that is an “arms length” sale
of all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”), 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 continue until the Expiration Date if
the Company continues as a going concern following the closing of any such True Asset Sale. 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. 

  
 2 








 C) Upon the closing of any Acquisition other than those particularly described in subsections
(A) and (B) 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. 

D) Notwithstanding the foregoing provisions of this Section 1.6.2., in the event that the acquiror in an Acquisition does not agree to assume
this Warrant at and as of the closing thereof, this Warrant, to the extent not exercised or converted on or prior to such closing, shall terminate and be of no further force or effect as of immediately following such closing if all of the following
conditions are met: (i) the acquiror is subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, (ii) the class of stock or other security of the acquiror that would
be received by Holder in connection with such Acquisition were Holder to exercise or convert this Warrant on or prior to the closing thereof is listed for trading on a national securities exchange or approved for quotation on an automated
inter-dealer quotation system, and (iii) the value (determined as of the closing of such Acquisition in accordance with the definitive agreements therefor) of the acquiror stock and/or other securities that would be received by Holder in
respect of each Share were Holder to exercise or convert this Warrant on or prior to the closing of such Acquisition is equal to or greater than three (3) times the then-effective Warrant Price. 

As used in this Section 1.6, “Affiliate” shall mean any person or entity that owns or controls directly or indirectly ten
percent (10%) or more of the stock of Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers, directors, joint venturers
or partners, as applicable. 
 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. 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, and the Warrant Price shall be adjusted proportionately. The Company or its successor shall 

  
 3 








 
promptly issue to Holder an amendment to this Warrant setting forth the number and kind 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 exercise or conversion of this Warrant. The amendment to this Warrant shall provide for adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new
Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 
 2.3 Intentionally Omitted. 
 2.4 No Impairment. The Company shall not,
by amendment of its Certificate of Incorporation 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; provided, however, that notwithstanding the foregoing, nothing in this Section 2.4 shall restrict or impair the Company’s right to effect changes to the rights,
preferences, and privileges associated with the Shares with the requisite consent of the stockholders as may be required to amend the Certificate of Incorporation from time to time so long as such amendment affects the rights, preferences, and
privileges granted to Holder associated with the Shares in the same manner as the other holders of outstanding shares of the Class. 
 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 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 its Chief Financial 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) All Shares which may be issued upon the exercise of the purchase right represented by this Warrant shall, upon
issuance, 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.

 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 same class and series as the Shares, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; (b) to offer for subscription or sale
pro rata to the holders of the outstanding shares of the same class and series as the Shares any additional shares of any class or series of the Company’s stock; (c) to effect any reclassification, reorganization or recapitalization of the
outstanding 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 notice thereof at the same time and in the same manner as the Company
notifies the holders of the outstanding shares of the Class thereof. Company will also provide information requested by Holder reasonably necessary to enable the Holder to comply with the Holder’s accounting or reporting requirements, subject
to Holder being bound by customary confidentiality obligations. 
 3.3 No Shareholder Rights. Except as provided in
this Warrant, Holder will not have any rights as a shareholder of the Company until the exercise of this Warrant. 
 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 agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents that it has not been formed for the specific purpose of
acquiring this Warrant or the Shares. 
 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 investment in this Warrant and its underlying securities and has
such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities 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. 

4.4 Accredited Investor Status. Holder is an “accredited investor” within the meaning of Regulation D promulgated
under the Act. 
 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 

  
 5 








 
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. 
 ARTICLE 5. MISCELLANEOUS. 
 5.1 Term: This Warrant is exercisable in
whole or in part at any time and from time to time on or before the Expiration Date. 
 5.2 Legends. This Warrant
and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend in substantially the following form: 

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
SECURITIES LAWS OF ANY STATE AND, EXCEPT FOR AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 OF THAT CERTAIN WARRANT TO PURCHASE STOCK ISSUED BY THE COMPANY TO SILICON VALLEY BANK DATED AS OF DECEMBER 19, 2011 MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR, IN THE OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS EXEMPT FROM REGISTRATION. 
 5.3 Compliance with Securities Laws on Transfer.
This Warrant and the Shares issuable upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part without compliance with applicable
federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the
Company). The Company shall not require Silicon Valley Bank (“Bank”) to provide an opinion of counsel if the transfer is to Bank’s parent company, SVB Financial Group (formerly Silicon Valley Bancshares), or any other affiliate of
Bank. Additionally, the Company shall also not require an opinion of counsel if there is no material question as to the availability of current information as referenced in Rule 144(c), Holder represents that it has complied with Rule 144(d) and
(e) in reasonable detail, the selling broker represents that it has complied with Rule 144(f), and the Company is provided with a copy of Holder’s notice of proposed sale. 

5.4 Transfer Procedure. After receipt by Holder of the executed Warrant, Bank will transfer all of this Warrant to
Holder’s parent company, SVB Financial Group, by execution of an Assignment substantially in the form of Appendix 2. Subject to the provisions of Article 5.3 and upon providing Company with written notice, SVB Financial Group and any subsequent
Holder may transfer all or part of this Warrant or the Shares issuable upon exercise of this Warrant (or the securities issuable directly or indirectly, upon conversion of the Shares, if 

  
 6 








 
any) to any transferee, provided, however, in connection with any such transfer, SVB Financial Group or any subsequent Holder will give the Company notice of the portion of the Warrant being
transferred with the name, address and taxpayer identification number of the transferee and Holder will surrender this Warrant to the Company for reissuance to the transferee(s) (and Holder if applicable). The Company may refuse to transfer this
Warrant or the Shares to any person who directly competes with the Company (as determined by Holder), unless, in either case, the stock of the Company is publicly traded. Any transferee shall take this Warrant subject to all provisions and
restrictions contained herein. 
 5.5 Notices. All notices and other communications from the Company to the Holder,
or vice versa, shall be deemed delivered and effective when given personally or mailed by first-class registered or certified mail, postage prepaid, at such address, as may have been furnished to the Company or the Holder, as the case may (or on the
first business day after transmission by facsimile) be, in writing by the Company or such Holder from time to time. Effective upon receipt of the fully executed Warrant and the initial transfer described in Article 5.4 above, all notices to the
