of Stock: Series B Convertible Preferred Stock, $0.001 par value per share

Warrant
Price: $1,801 per Share, subject to adjustment

Issue
Date: March 6, 2014

Expiration
Date: March 5, 2024 See also Section 5.1(b).

Credit
Facility: This Warrant to Purchase Stock (“Warrant”) is issued in connection with that certain Loan
and Security Agreement of even date herewith between Silicon Valley Bank and the Company (as amended and/or modified and in effect
from time to time, the “Loan Agreement”).

 

THIS
WARRANT CERTIFIES THAT, for good and valuable consideration, SILICON VALLEY BANK (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 non-assessable shares (the “Shares”) of the above-stated Type/Series
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 Section 2 of this Warrant, subject to the provisions and upon
the terms and conditions set forth in this Warrant. Reference is made to Section 5.4 of this Warrant whereby Silicon Valley Bank
shall transfer this Warrant to its parent company, SVB Financial Group.

 

Section 1.  EXERCISE.

 

1.1        Method
of Exercise. Holder may at any time and from time to time exercise this Warrant, in whole or in part, by delivering to the
Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto
as Appendix 1 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set forth in Section 1.2, a 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        Cashless
Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Warrant Price in the manner as specified in
Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive Shares equal
to the value of this Warrant, or portion hereof as to which this Warrant is being exercised. Thereupon, the Company shall issue
to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula:

 

X
=       Y(A-B)/A

 

where:

 

X
=       the number of Shares to be issued to the Holder;

 

    

     

    

 

Y
=         the number of Shares with respect to which this Warrant is being exercised (inclusive
of the Shares surrendered to the Company in payment of the aggregate Warrant Price);

 

A
=         the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and

 

B
=         the Warrant Price.

 

1.3          Fair
Market Value. If the Company’s common stock is then traded or quoted on a nationally recognized securities exchange,
inter-dealer quotation system or over-the-counter market (a “Trading Market”) and the Class is common
stock, the fair market value of a Share shall be the closing price or last sale price of a share of common stock reported for
the Business Day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the
Company. If the Company’s common stock is then traded in a Trading Market and the Class is a series of the Company’s
convertible preferred stock, the fair market value of a Share shall be the closing price or last sale price of a share of the
Company’s common stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together
with its Notice of Exercise to the Company multiplied by the number of shares of the Company’s common stock into which a
Share is then convertible. If the Company’s common stock is not traded in a Trading Market, the Board of Directors of the
Company shall determine the fair market value of a Share in its reasonable good faith judgment.

 

1.4          Delivery
of Certificate and New Warrant. Within a reasonable time after Holder exercises this Warrant in the manner set forth in Section
1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise
and, if this Warrant has not been fully exercised and has not expired, a new warrant of like tenor representing the Shares not
so acquired.

 

1.5          Replacement
of Warrant. 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, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for cancellation,
the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor
and amount.

 

1.6          Treatment
of Warrant Upon Acquisition of Company.

 

(a)          Acquisition.
For the purpose of this Warrant, “Acquisition” means any transaction or series of related transactions
involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company
(ii) any merger or consolidation of the Company into or with another person or entity (other than a merger or consolidation effected
exclusively to change the Company’s domicile), or any other corporate reorganization, in which the stockholders of the Company
in their capacity as such immediately prior to such merger, consolidation or reorganization, own less than a majority of the Company’s
(or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization
(or, if such Company stockholders beneficially own a majority of the outstanding voting power of the surviving or successor entity
as of immediately after such merger, consolidation or reorganization, such surviving or successor entity is not the Company);
or (iii) any sale or other transfer by the stockholders of the Company of shares representing at least a majority of the Company’s
then-total outstanding combined voting power.

 

    2

     

    

 

(b)          Treatment
of Warrant at Acquisition. In the event of an Acquisition in which the consideration to be received by the Company’s
stockholders consists solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public
Acquisition”), and the fair market value of one Share as determined in accordance with Section 1.3 above would be
greater than the Warrant Price in effect on such date immediately prior to such Cash/Public Acquisition, and Holder has not exercised
this Warrant pursuant to Section 1.1 above as to all Shares, then this Warrant shall automatically be deemed to be Cashless Exercised
pursuant to Section 1.2 above as to all Shares effective immediately prior to and contingent upon the consummation of a Cash/Public
Acquisition. In connection with such Cashless Exercise, Holder shall be deemed to have restated each of the representations and
warranties in Section 4 of the Warrant as the date thereof and the Company shall promptly notify the Holder of the number of Shares
(or such other securities) issued upon exercise. In the event of a Cash/Public Acquisition where the fair market value of one
Share as determined in accordance with Section 1.3 above would be less than the Warrant Price in effect immediately prior to such
Cash/Public Acquisition, then this Warrant will expire immediately prior to the consummation of such Cash/Public Acquisition.

 

(c)          Upon
the closing of any Acquisition other than a Cash/Public Acquisition, the acquiring, surviving or successor entity shall assume
the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property
as would have been paid for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the
provisions of this Warrant.

 

(d)          As
used in this Warrant, “Marketable Securities” means securities meeting all of the following requirements:
(i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required reports
and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer
that would be received by Holder in connection with the Acquisition were Holder to exercise this Warrant on or prior to the closing
thereof is then traded in Trading Market, and (iii) following the closing of such Acquisition, Holder would not be restricted
from publicly re-selling all of the issuer’s shares and/or other securities that would be received by Holder in such Acquisition
were Holder to exercise this Warrant in full on or prior to the closing of such Acquisition, except to the extent that any such
restriction (x) arises solely under federal or state securities laws, rules or regulations, and (y) does not extend beyond six
(6) months from the closing of such Acquisition.

 

1.7          Stockholders
Agreement. Upon any exercise of this Warrant, Holder shall, if the Company so requests in writing, become a party (of the
same type as the other holders of outstanding shares of the Class who are parties thereto) to, by execution and delivery to the
Company of a counterpart signature page, joinder agreement, instrument of accession or similar instrument, that certain Amended
and Restated Stockholders Agreement dated August 14, 2013 among the Company and the other parties named therein (as amended and
in effect from time to time, the “Stockholders Agreement”), solely with respect to the Shares issued
upon such exercise (and the shares of Common Stock, if any, issued upon conversion of such Shares), solely to the extent that
all holders of outstanding shares of the Class are then parties thereto, and solely to the extent such agreement is then by its
terms in force and effect.

 

Section 2. 
ADJUSTMENTS TO THE SHARES AND WARRANT PRICE.

 

2.1          Stock
Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the Class
payable in common stock or other securities or property (other than cash), then upon exercise of this Warrant, for each Share
acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which
Holder would have received had Holder owned the Shares of record as of the date the dividend or distribution 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.

 

    3

     

    

 

2.2          Reclassification,
Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Class are reclassified,
exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then
from and after the consummation of such event, this Warrant will be exercisable for the number, class and series of Company securities
that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further
adjustment thereafter from time to time in accordance with the provisions of this Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events.

 

2.3          Conversion
of Preferred Stock. If the Class is a class and series of the Company’s convertible preferred stock, in the event that
all outstanding shares of the Class are converted, automatically or by action of the holders thereof, into common stock pursuant
to the provisions of the Company’s Certificate of Incorporation, as amended and in effect from time to time (the “Charter”),
including, without limitation, in connection with the Company’s initial, underwritten public offering and sale of its common
stock pursuant to an effective registration statement under the Act (the “IPO”), then from and after
the date on which all outstanding shares of the Class have been so converted, this Warrant shall be exercisable for such number
of shares of common stock into which the Shares would have been converted had the Shares been outstanding on the date of such
conversion, and the Warrant Price shall equal the Warrant Price in effect as of immediately prior to such conversion divided by
the number of shares of common stock into which one Share would have been converted, all subject to further adjustment thereafter
from time to time in accordance with the provisions of this Warrant.

 

2.4          Adjustments
for Diluting Issuances. Without duplication of any adjustment otherwise provided for in this Section 2, the number of shares
of common stock issuable upon conversion of the Shares shall be subject to anti-dilution 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 (and
subject to waiver by the required holders of the outstanding shares of the Class in accordance with the Charter).

 

2.5          No
Fractional Share. No fractional Share shall be issuable upon exercise of this 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 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 (i) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the then-effective
Warrant Price.

 

2.6          Notice/Certificate
as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the Company, at the Company’s
expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, Class and/or
number of Shares and facts upon which such adjustment is based. The Company shall, upon written request from Holder, furnish Holder
with a certificate of its Chief Executive Officer or Chief Financial Officer, including computations of such adjustment and the
Warrant Price, Class and number of Shares in effect upon the date of such adjustment. Notwithstanding the foregoing provisions
of this Section 2.6, in the event of an adjustment pursuant to Section 2.3, the Company shall only be required to provide Holder
with such notices as are required to be delivered to holders of the outstanding shares of the Class pursuant to the Charter regarding
anti-dilution protection as and when required thereunder.

Section 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

such shares were sold.

 

(b)           All
Shares which may be issued upon the exercise of this Warrant, and all securities, if any, issuable upon conversion of the Shares,
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, under the Stockholders Agreement or under applicable federal and state
securities laws. The Company covenants that it shall at all times cause to be reserved and kept available out of its authorized
and unissued capital stock such number of shares of the Class, common stock and other securities as will be sufficient to permit
the exercise in full of this Warrant and the conversion of the Shares into common stock or such other securities.

 

(c)           The
Company’s capitalization table attached hereto as Schedule 1 is true and complete, in all material respects, as of the Issue
Date.

 

3.2           Notice
of Certain Events. If the Company proposes at any time to:

 

(a)           declare
any dividend or distribution upon the outstanding shares of the Class or common stock, whether in cash, property, stock, or other
securities and whether or not a regular cash dividend;

 

(b)           offer
for subscription or sale pro rata to the holders of the outstanding shares of the Class any additional shares of any class or

any reclassification, exchange, combination, substitution, reorganization or recapitalization of the outstanding shares of the
Class;

 

(d)           effect
an Acquisition or to liquidate, dissolve or wind up; or

 

(e)           effect
an IPO;

 

then,
in connection with each such event, the Company shall give Holder:

 

(1)           in
the case of the matters referred to in (a) and (b) above, at least seven (7) Business Days prior written notice of the earlier
to occur of the effective date thereof or 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 outstanding shares of the Class will be entitled thereto) or for determining
rights to vote, if any;

 

(2)           in
the case of the matters referred to in (c) and (d) above at least seven (7) Business Days prior written notice of the date when
the same will take place (and specifying the date on which the holders of outstanding shares of the Class will be entitled to
exchange their shares for the securities or other property deliverable upon the occurrence of such event and such reasonable information

and

 

    5

     

    

 

(3)        with
respect to the IPO, at least seven (7) Business Days prior written notice of the date on which the Company proposes to file its
registration statement in connection therewith.

 

The
Company will also provide information requested by Holder that is reasonably necessary to enable Holder to comply with Holder’s
accounting or reporting requirements; provided, that Holder agrees to treat and hold all such information in accordance
with Section 12.9 of the Loan Agreement.

 

Section 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 are being 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 is aware
of the Company’s business affairs and financial condition and 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 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 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. Holder is aware of the provisions of Rule 144 promulgated under the Act.

 

4.6        Market Stand-off Agreement. The Holder
agrees that the Shares shall be subject to the Market Standoff provisions in Section 12 of the Company’s Amended and Restated
Registration Rights Agreement dated August 14, 2013, as amended and/or restated and in effect from time to time.

 

4.7        No Voting Rights. Holder, as a Holder
of this Warrant, will not have any voting rights until the exercise of this Warrant.

 

    6

deliver a certificate representing the Shares (or such other securities) issued upon such exercise to Holder.

Financial Group or any subsequent Holder will give the . Company notice of the portion of the Warrant and/or Shares (and/or securities
issued upon conversion of the Shares, if any) 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 provided further, that any subsequent transferee other than SVB Financial Group shall agree in writing with the Company to
be bound by all of the terms and conditions of this Warrant; and provided further, that the transfer of any Shares issued upon
exercise hereof shall be subject to the terms and provisions of the Stockholder Agreement. Notwithstanding any contrary provision
herein, at all times prior to the IPO, Holder may not, without the Company’s prior written consent, transfer this Warrant
or any portion hereof, or any Shares issued upon any exercise hereof, or any shares or other securities issued upon any conversion
of any Shares issued upon any exercise hereof, to any person or entity who directly competes with the Company, except in connection
with an Acquisition of the Company by such a direct competitor.
