time) among Oxford Finance LLC, successor in interest to Oxford Finance Corporation (“Oxford”), as Lender and Administrative Agent, the Lenders party thereto, and the Company.

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, OXFORD FINANCE LLC (together with any
successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid and nonassessable shares (as described above, 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 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 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. The fair market value of a Share shall be the average of the
closing prices for a share of common stock reported for the ten (10) business days immediately before Holder delivers this Warrant together with its Notice of Exercise to the Company. 

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 securities before the
transaction beneficially own less than a majority of the outstanding voting securities of the surviving 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 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 as particularly described in subsection (A) above, the
surviving or 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. 

  
 2 

 C) Notwithstanding the foregoing provisions of Section 1.6.2(B), in the event of an Acquisition in
which all of the following requirements are met, this Warrant, to the extent not exercised or converted on or prior to the closing of such Acquisition, shall terminate and be of no further force or effect as of immediately following such closing:
(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 and series of shares 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) Holder would not be contractually restricted from publicly re-selling within three (3) months following the closing of such Acquisition, nor restricted under applicable securities laws from publicly re-selling
within six (6) months following the closing of such Acquisition (assuming for such determination that Holder would convert this Warrant pursuant to Article 1.2 above), all of the acquiror shares and/or other securities that would be received by
Holder in such Acquisition were Holder to exercise or convert this Warrant in full on or prior to the closing thereof. 
 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. 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 Certificate of Incorporation upon the closing of the IPO. The Company or its successor shall 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

  
 3 

 
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 same series and class as the Shares. 
 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: 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, be duly authorized, validly issued, fully paid and nonassessable, and free of any liens and encumbrances except for restrictions
on transfer provided for herein or under applicable federal and state securities laws. 

  
 4 

 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 all 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 (other than pursuant to contractual pre-emptive rights); (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 written
notice thereof at the same time and in the same manner as the Company gives written notice thereof to holders of the outstanding shares of the Class. 
 3.3 Registration Under Securities Act of 1933, as amended. The Company agrees that the Shares shall have certain incidental, or “Piggyback,” and S-3 registration rights pursuant to and as
set forth in the Company’s Amended and Restated Investors’ Rights Agreement dated December 13, 2007, as amended and in effect from time to time (the “IRA”). For the avoidance of doubt, such registration rights shall not
include demand registration rights (except to the extent that S-3 rights may be deemed demand rights). The provisions set forth in the IRA 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 same
series and class as the Shares granted to the Holder. 
 3.4 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. 

  
 5 

 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

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.

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 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. 
 4.6 QIB. Holder is a “qualified institutional buyer”
as defined in Rule 144A promulgated under the Act.

investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to any
“affiliate” (as such term is defined in Regulation D promulgated under the Act) of Holder, provided that any such transferee is an “accredited investor” as defined in Regulation D promulgated under the Act. Additionally, the
Company shall also not require an opinion of counsel if there is no material question as to the availability of an exemption to registration under Rule 144, including without limitation, 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, Oxford may transfer all or part of this

notice, Oxford, any such Oxford Affiliate and any subsequent Holder may transfer all or part of this Warrant or the Shares issuable upon exercise of this Warrant (or the Shares issuable directly or indirectly, upon conversion of the Shares, if any)
to any transferee, provided, however, in connection with any such transfer, the Oxford Affiliate(s) 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).

upon Expiration. In the event that, upon the Expiration Date, the fair market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Warrant Price in
effect on such date, then this Warrant shall automatically be deemed on and as of such date to be converted pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised or
converted, and the Company shall promptly deliver a certificate representing the Shares (or such other securities) issued upon such conversion to Holder. 
 5.9 Counterparts. This Warrant may be executed in counterparts, all of which together shall constitute one and the same agreement.

within six (6) months following the closing of such Acquisition (assuming for such determination that Holder would convert this Warrant pursuant to Article 1.2 above), all of the acquiror shares and/or other securities that would be received by

 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. 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 Certificate of Incorporation upon the closing of the IPO. The Company or its successor shall 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 

  
 3 

 
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 same series and class as the Shares. 

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: 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, be duly authorized, validly
issued, fully paid and nonassessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. 

  
 4 

 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 all 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 (other than pursuant to contractual pre-emptive rights); (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 written
notice thereof at the same time and in the same manner as the Company gives written notice thereof to holders of the outstanding shares of the Class. 
 3.3 Registration Under Securities Act of 1933, as amended. The Company agrees that the Shares shall have certain incidental, or “Piggyback,” and S-3 registration rights pursuant to and as
set forth in the Company’s Amended and Restated Investors’ Rights Agreement dated December 13, 2007, as amended and in effect from time to time (the “IRA”). For the avoidance of doubt, such registration rights shall not
include demand registration rights (except to the extent that S-3 rights may be deemed demand rights). The provisions set forth in the IRA 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 same
series and class as the Shares granted to the Holder. 
 3.4 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. 

  
 5 

 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 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. 
 4.6 QIB. Holder is a “qualified institutional buyer”
as defined in Rule 144A promulgated under the Act. 
 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 ACT, OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT 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 JUNE 30,
2011, MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAW 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. 

  
 6 

 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 (the “Bank”) to provide an opinion of counsel if the transfer is to any “affiliate” (as such term is defined in Regulation D promulgated under the Act; including but not limited to 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 an exemption to registration under Rule 144,
including without limitation, 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 Shares issuable directly or indirectly, upon
conversion of the Shares, if 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) and transferee agrees to be bound by the terms of this Warrant. The
Company may refuse to transfer this Warrant or the Shares to any person or entity who directly competes with the Company, as reasonably determined by the Company in its good faith business judgment, 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 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. All notices to Holder shall be addressed as follows

 5.6 Waiver. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver,
discharge or termination is sought. 
 5.7 Attorney’s Fees. In the event of any dispute between the parties
concerning the terms and provisions of this Warrant, the party prevailing in such dispute shall be entitled to collect from the other party all costs incurred in such dispute, including reasonable attorneys’ fees. 

5.8 Automatic Conversion upon Expiration. In the event that, upon the Expiration Date, the fair market value of one Share (or
other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be
converted pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised or converted, and the Company shall promptly deliver a certificate representing the Shares (or such other
securities) issued upon such conversion to Holder. 
 5.9 Counterparts. This Warrant may be executed in counterparts, all
of which together shall constitute one and the same agreement. 
 5.10 Governing Law. This Warrant shall be governed by
and construed in accordance with the laws of the State of California, without giving effect to its principles regarding conflicts of law. 
 5.11 Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY AND HOLDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF
