                         or its assignee (“Holder”) is entitled to purchase the number of fully paid and nonassessable
shares of the class of securities (the “Shares”) of the corporation (the “Company”) at the initial exercise price per Share (the “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 this warrant and a duly executed Notice of Exercise in
substantially the form attached as Appendix 1 to the principal office of the Company. Holder shall also deliver to the Company a check for the aggregate Warrant Price for the Shares being purchase. 

1.2 Intentionally Omitted. 

1.3 Intentionally Omitted. 

1.4 Fair Market Value. If the Shares are traded regularly in a public market, the fair market value of the Shares shall be the closing
price of the Shares (or the closing price of the Company’s stock into which the Shares are convertible) reported for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the Shares are not regularly
traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. 

1.5 Delivery of Certificate and New Warrant. Promptly after Holder exercises this warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this warrant has not been fully exercised and has not expired, a new warrant representing the Shares not so acquired. 

1.6 Replacement of Warrants. On receipt of evidence reasonable 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 at its expense shall execute and deliver, in lieu of this warrant, a new warrant of like tenor. 
 1.7 Repurchase on Sale,
Merger, or Consolidation of the Company. 
 1.7.1 “Acquisition.” For the purpose of this warrant,
“Acquisition” means (a) any sale, license, or other disposition of all or substantially all of the assets (including intellectual property) of the Company, or (b)

 
any reorganization, consolidation, merger or sale of the voting securities of the Company or any other transaction where the holders of the Company’s securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction; provided that, for the purposes of (a) and (b), above, any transaction involving only the license of the Company’s
trade name or a transaction in which the Company sells or issues its equity securities to investors (or their affiliates) in the Company as of the Issue Date, shall not be deemed an Acquisition. 

1.7.2 Assumption of Warrant. If upon the closing of any Acquisition the successor entity assumes the obligations of this warrant, then
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 shall be adjusted accordingly. The Company shall use reasonable efforts to cause the surviving corporation to assume the obligations of this warrant. 

1.7.3. Nonassumption. If upon the closing of any Acquisition the successor entity does not assume the obligations of this warrant and
Holder has not otherwise exercised this warrant, in full, then Holder shall participate in the Acquisition on the same terms as other holders of the same class of securities of the Company. 

1.8 Adjustment in Underlying Preferred Stock Price and Exercise Price. If on or before August 8, 2008, the Company sells and
issues to any investors preferred stock with aggregate gross proceeds to the Company of at least $1,400,000, this Warrant shall, concurrent with the issuance of such shares of preferred stock, automatically be adjusted to instead be exercisable for
shares of the same series and class and bearing the same rights, preferences, and privileges of such shares of stock, with the Warrant Price hereunder adjusted to equal the per share purchase price of such stock, and the number of such shares
subject to this Warrant adjusted to equal (i) Seventeen Thousand Dollars ($17,000), divided by (ii) such modified per share Warrant Price. Any adjustments made to the Warrant pursuant to this Section 1.8 shall be in addition to any
adjustments made pursuant to Article 2, below. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on its common stock payable in common stock, or other
securities, subdivides the outstanding common stock into a greater amount of common stock, 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 or subdivision occurred. 
 2.2
Reclassification, Exchange or Substitution; Automatic Exchange of Warrant. (a) 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
of this warrant, Holder shall be entitled to receive, upon exercise 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 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 a registered public offering of the Company’s common stock. The Company or its successor shall promptly issue to Holder a new warrant for such new securities or other
property. The new 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 reclassifications, exchanges substitutions, or other events. 
 (b) Immediately upon the automatic
conversion of the Company’s Series A Preferred Stock as provided under the Company’s Amended and Restated Certificate of Incorporation (any event triggering such automatic conversion of the Series A Preferred Stock is referred to as an
“Automatic Exchange Event”), Holder shall, upon no less than ten (10) business days prior written notice from the Company, deliver this warrant to the Company for cancellation and exchange upon the effectiveness of the Automatic
Exchange Event, and the Company immediately shall issue and deliver to the Holder a replacement warrant containing substantially the same terms as this warrant except that the replacement warrant shall be exercisable for that number of shares of the
Company’s 

 
common stock issuable upon conversion of all shares of Series A Preferred Stock that could be purchased by Holder upon full exercise of this Warrant on the effective date of the Automatic
Exchange Event. 
 2.3 Adjustments for Combinations, Etc. If the outstanding Shares are combined or consolidated, by reclassification
or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased. If the outstanding Shares are combined or consolidated, by reclassification or otherwise, into a greater number of shares, the Warrant Price shall be
proportionally decreased. 
 2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of Shares issuable upon
exercise of this warrant shall be subject to adjustment, from time to time, in the manner set forth on Exhibit A. 
 2.5 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 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. 
 2.6 Certificate as to
Adjustments. Upon each adjustment of the Warrant Price, the Company at its expense shall 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 in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 

2.7 Fractional Shares. No fractional Shares shall be issuable upon exercise 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 of the Warrant, the Company shall eliminate such fractional share interest by paying Holder amount computed by multiplying the fractional interest by
the fair market value of a full Share. 
 2.8 Shareholders’ Agreement. Holder shall execute and become a party to the
Stockholders’ Agreement dated April 20, 2004 and all Shares (and any shares of common stock issued upon conversion thereof) shall be subject to all of the terms and conditions set forth in Sections 2.2 – 2.9, 2.11, 2.12, 7 and 8

1. Exercise. 
 1.1 Method of
Exercise. Subject to the vesting provisions of this Warrant, 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

 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 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 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. 

(a) If (i) this Warrant is exercised immediately prior to the effectiveness of the Company’s registration statement
for the initial public offering of the Company’s common stock and (ii) the Class is common stock, then the fair market value of a Share shall be the initial public offering price per share of common stock specified in the final prospectus
with respect to the public offering. 
 (b) If (i) this Warrant is exercised immediately prior to the effectiveness of
the Company’s registration statement for the initial public offering of the Company’s common stock and (ii) the Class is a series of the Company’s convertible preferred stock, then the fair market value of a Share shall be the
initial public offering price per share of common stock specified in the final prospectus with respect to the public offering multiplied by the number of shares of the Company’s common stock into which a Share is then convertible. 

(c) If (i) 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”), (ii) Sections 1.3(a) and (b) of this Warrant do not apply for determining the fair market value of a Share, and (iii) the Class is common
stock, then 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 (or, if applicable, the Business Day immediately before the date on which this Warrant is automatically exercised pursuant to Section 3.2 or Section 5.1(b) of this Warrant). 

(d) If (i) the Company’s common stock is then traded on a Trading Market, (ii) Sections 1.3(a) and (b) of
this Warrant do not apply for determining the fair market value of a Share, and (iii) the Class is a series of the Company’s convertible preferred stock, then 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 (or, if applicable, the Business Day immediately before
the date on which this Warrant is automatically exercised pursuant to Section 3.2 or Section 5.1(b) of this Warrant) multiplied by the number of shares of the Company’s common stock into which a Share is then convertible. 

(e) If Sections 1.3(a), (b), (c) and (d) of this Warrant do not apply for determining the fair market value of a
Share, then 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 (not to exceed ten
(10) Business Days) after Holder exercises this Warrant in the manner set forth in Section 1.1 or 1.2 above (including, without limitation, an automatic exercise pursuant to Section 3.2 or Section 5.1(b) of this Warrant), the
Company shall, if requested by Holder, 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 (without any obligations to post a bond or other security) 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.

 2. Adjustments to the Shares and Warrant Price. In order to prevent dilution of the purchase rights granted under this Warrant, the Warrant Price
and the number of Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 2. 

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 capital 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. 

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 of this Warrant, Holder shall be entitled to receive, upon exercise 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 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 a registered public offering of the Company’s common stock. Upon the closing of an
Acquisition (as defined in Section 5.1 below), and subject to 

  
 -4- 

 
Section 5.1 hereof, the successor entity shall assume the obligations of this Warrant, and this Warrant thereafter 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 Company or its successor shall promptly issue to Holder
a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 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 Section 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other
events. 
 2.3 Adjustment upon Issuance of Common Stock. If, at any time after the Issue Date but prior to the date of effectiveness
of the Company’s registration statement for the initial public offering of the Company’s common stock, the Company shall issue (or, pursuant to Section 2.3(d) below), shall be deemed to have issued) any common stock other than
“Excluded Stock” (as defined in the Company’s Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”)) for a consideration per share less than the Warrant Price in effect immediately
prior to the issuance of such common stock (excluding stock dividends, subdivisions, split-ups, combinations, dividends or recapitalizations that are covered by Sections 2.1 and 2.2 above), the Warrant Price in effect immediately after each
such issuance shall forthwith, except as provided herein, be adjusted to a price equal to the quotient obtained by multiplying such Warrant Price by a fraction (I) the numerator of which shall be (x) the number of shares of common stock
outstanding at the close of business on the day immediately preceding the date of such issuance or sale, plus (y) the number of shares of common stock which the aggregate consideration received (or by the express provisions hereof shall be
deemed to have been received) by the Company for the total number of additional shares of common stock so issued or sold would purchase at such Warrant Price then in effect and (II) the denominator of which shall be the number of shares of common
stock outstanding at the close of business on the date of such issuance or sale (after giving effect to such issuance or sale) of the additional shares of common stock. Upon each such adjustment of the Warrant Price under this Section 2.3, the
number of Shares shall be adjusted to the number of Shares determined by multiplying the Warrant Price in effect immediately prior to such adjustment by the number of Shares acquirable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Warrant Price resulting from such adjustment. For the purposes of any adjustment of the Warrant Price pursuant to this Section 2.3, the following provisions shall be applicable: 

(a) The number of shares of common stock outstanding shall include, in addition to the number of shares of common stock
actually outstanding, (I) the number of shares of common stock into which the then outstanding shares of each series of the Company’s convertible preferred stock could be converted if fully converted on the day immediately preceding the
issuance or sale or deemed issuance or sale of the additional shares of common stock; and (II) the number of shares of common stock which would be obtained through the exercise or conversion of all rights, options and convertible securities
outstanding on the day immediately preceding the issuance or sale or deemed issuance or sale of the additional shares of common stock. 

  
 -5- 

 (b) In the case of the issuance of common stock for cash, the consideration shall
be deemed to be the amount of cash paid therefor after deducting any discounts or commission paid or incurred by the Company in connection with the issuance and sale thereof. 

(c) In the case of the issuance of common stock for a consideration in whole or in part other than cash, the consideration
other than cash shall be deemed to be the fair value thereof as reasonably determined by the Board of Directors of the Company, in accordance with generally accepted accounting treatment; provided, however, that if, at the time of such
determination, the Company’s common stock is traded on a Trading Market, such fair market value per share of common stock as determined by the Board of Directors of the Company shall not exceed (i) if the shares of common stock are then
traded on a securities exchange, the average of the closing prices of the common stock on such exchange over the 20 trading day period ending three (3) business days prior to such determination or (ii) if the shares of common stock are
then traded over-the-counter, the average of the closing bid prices over the 30-day period ending three (3) business days prior to such determination; provided, however, that if such prices are not available for the period required, such fair
market value shall be determined in good faith by the Board of Directors of the Company. 
 (d) In the case of the issuance of
(i) options to purchase or rights to subscribe for common stock (directly or indirectly), (ii) securities by their terms convertible into or exchangeable for common stock (directly or indirectly), or (iii) options to purchase or
rights to subscribe for such convertible or exchangeable securities: 
 (1) the aggregate maximum number of shares of common
stock deliverable upon exercise of such options to purchase or rights to subscribe for common stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in
the manner provided in Sections 2.3(b) and 2.3(c) above), if any, received by the Company upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the common stock covered thereby; 

(2) the aggregate maximum number of shares of common stock deliverable upon conversion of or in exchange for any such
convertible or exchangeable securities, or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof, shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the additional minimum consideration, if any, to be received by the Company upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in Sections 2.3(b) and 2.3(c) above); 

  
 -6- 

 (3) on any change in the number of shares of common stock deliverable upon
exercise of any such options or rights or conversion of or exchange for such convertible or exchangeable securities, or on any change in the minimum purchase price of such options, rights or securities, other than a change resulting from the
anti-dilution provisions of options, rights or securities, the Warrant Price shall forthwith be readjusted to such Warrant Price as would have been obtained had the adjustment made upon (x) the issuance of such options, rights or securities not
exercised, converted or exchange prior to such change or (y) the options or rights related to such securities not converted or exchanged prior to such change, as the case may be, been made upon the basis of such change; and 

(4) on the expiration of any such options or rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable securities, the Warrant Price shall forthwith be readjusted to such Warrant Price as would have been obtained had the adjustment made upon the issuance of such options
or rights, convertible or exchangeable securities or options or rights related to such convertible or exchangeable securities, as the case may be, been made upon the basis of the issuance of only the number of shares of common stock actually issued
upon the exercise of such options or rights, upon the conversion or exchange of such convertible or exchangeable securities or upon the exercise of the options or rights related to such convertible or exchangeable securities, as the case may be.

 2.4 Minimal Adjustments. No adjustment in the Warrant Price need be made if such adjustment would result in a change in the
Warrant Price of less than $0.001. Any adjustment of less than $0.001 which is not made shall be carried forward and shall be made at the time of and together with any subsequent adjustment which, on a cumulative basis, amounts to an adjustment of
$0.001 or more in the Warrant Price. 
 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 (not less than ten (10) Business Days after the effectiveness of such adjustment) 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 Financial Officer, including computations of such adjustment and the Warrant Price, Class and number
of Shares in effect upon the date of such adjustment.

 3. Representations and Covenants of the Company. 

3.1 Representations and Warranties. The Company represents and warrants to, and agrees with, Holder as follows: 

(a) All Shares issuable 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 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 and other securities as will be sufficient to permit the exercise in full of
this Warrant and, if applicable, the conversion of the Shares into common stock or such other securities. 
 (b) The
Company’s capitalization table attached hereto as Schedule 1 is true and complete, in all material respects, as of the Issue Date. 

(c) This Warrant and the Shares issuable upon the exercise of this Warrant constitute “Excluded Securities” as such
term is defined in the Company’s Eighth Amended and Restated Stockholders’ Agreement dated as of October 18, 2013, as amended by the First Amendment to Eighth Amended and Restated Stockholders’ Agreement dated December 20,
2013 and the Second Amendment to Eighth Amended and Restated Stockholders’ Agreement dated December 30, 2013 (as amended, the “Stockholders’ Agreement”). 

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 securities into which the Class is
convertible, 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 holders of the outstanding shares of the Class or securities into which the Class is convertible any additional shares of any class or series of the Company’s stock (other than pursuant to contractual
pre-emptive rights in which the Holder has no right to participate); 
 (c) effect any reclassification, exchange,
combination, substitution, reorganization or recapitalization of the outstanding shares of the Class or securities into which the Class is convertible; or 

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

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

(1) at least seven (7) Business Days prior written notice of the date on which a record will be taken for such dividend,
distribution, or subscription rights 

  
 -8- 

 
(and specifying the date on which holders of outstanding shares of the Class will be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in
(a) and (b) above; and 
 (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 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); provided that if a combination under (c) above takes place in connection with the Company’s initial public offering, it shall be sufficient to provide in the notice that such combination will
take place immediately prior to the effectiveness or closing of the initial public offering, as the case may be, even if the precise date for such event is not known at such time. 

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. 
 3.3 Registration Rights. The Shares (or if the Shares are a Class other than common stock, the shares of
common stock into which the Shares are convertible) shall be “Registrable Securities” (as such term is defined in the Stockholders’ Agreement) and Holder shall have the rights and obligations of a “Holder” under
Section 2 of the Stockholders’ Agreement. 
 3.4 Joinder to Stockholders’ Agreement. 

(a) Simultaneously with the execution of this Warrant, the Holder shall execute and deliver to the Company a joinder to the
Stockholders’ Agreement, thereby agreeing (subject to Section 3.5(b) below) to be bound by all obligations and receive all rights to the Stockholders’ Agreement, to be held in escrow until the exercise of this Warrant. All shares of
common stock issued upon exercise of this Warrant shall include any legends required under the Stockholders’ Agreement. 

(b) Notwithstanding Section 3.4(a) above, in addition to the limitations and protections currently set forth in the last
sentence of Section 7.1 of the Stockholders’ Agreement, in no event shall Holder be required to enter into a release of claims in connection with an “Approved Sale” in Holder’s capacity as a lender or lender’s agent to
the Company or any parent or subsidiary of the Company. 
 3.5 Information Rights. So long as the Holder holds this Warrant and/or
any of the Shares, the Company shall deliver to the Holder (a) within one hundred eighty (180) days after the end of each fiscal year of the Company, the annual audited financial statements of the Company and (b) within thirty
(30) days after the end of each of the first three quarters of each fiscal year, the Company’s quarterly, unaudited financial statements, provided the Company need not provide such information for any period in which the Company has filed
a periodic report on Form 10-K or Form 10-Q (as applicable) with the Securities and Exchange Commission.

 3.6 Listing of Shares. If shares or other securities of the Class are listed on any
Trading Market at, or at any time after, the time this Warrant is exercised, the Company shall use commercially reasonable efforts to cause the Shares (or any securities issued upon conversion of the Shares, if applicable), upon such exercise, to be
listed on such Trading Market. 
 3.7 Expenses and Taxes; Liabilities. The Company shall pay all expenses in connection with, and all
taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of Shares upon exercise of this Warrant; provided that the Company shall not be required to pay any tax or governmental charge that may be imposed
with respect to any applicable withholding or the issuance or delivery of Shares to any person other than the Holder. Nothing contained in this Warrant shall be construed as imposing any liabilities on Holder to purchase any securities of the
Company (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. 

4. Representations and Warranties of Holder. 

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. 

  
 -10- 

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

5.1 Term and Automatic Conversion. 

(a) Term. Subject to the vesting provisions of this Warrant and the provisions of this Section 5, this Warrant is
exercisable in whole or in part at any time and from time to time on or before 6:00 PM, Pacific Time, on the Expiration Date and shall be void thereafter. 

(b) Automatic Cashless Exercise 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 exercised pursuant to Section 1.2 above as to all Shares (or such other securities) that have vested in accordance with the provisions of this Warrant for which it shall not previously have been exercised, and the Company shall, if
requested by Holder, within a reasonable time (not to exceed ten (10) Business Days), deliver a certificate representing the Shares (or such other securities) issued upon such exercise to Holder. 

(c) Acquisitions. For the purpose of this Warrant, “Acquisition” means any sale, license, or other disposition
of all or substantially all of the assets of the Company, or any reorganization, consolidation, or merger of the Company where the holders of the Company’s securities before the transaction beneficially own less than 50% of the outstanding
voting securities of the surviving entity after the transaction. In the event of an Acquisition in which the consideration is solely cash and/or marketable securities, then this Warrant, notwithstanding the provisions of Section 3.2 hereof and
subject to the vesting provisions of this Warrant, shall be deemed exercised in accordance with the provisions of Section 1.2 immediately prior to the closing of the Acquisition; otherwise, this Warrant shall terminate. 

  
 -11- 

 5.2 Legends. 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: 
 THE SHARES EVIDENCED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER SAID
ACT AND LAWS OR IN THE OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER, SUCH OFFER, SALE, PLEDGE OR OTHER TRANSFER IS EXEMPT FROM SUCH 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 applicable) may not be transferred or assigned in whole or in part except in compliance with applicable federal and state securities laws by the transferor and the transferee. The
Company shall not require Holder to provide an opinion of counsel if the transfer is to any affiliate 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 Rule 144 promulgated under the Act. 

5.4 Transfer Procedure. Subject to the provisions of Section 5.3 of this Warrant, the initial Holder and each 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 applicable) to any transferee, provided, however, in connection with
any such transfer, the initial Holder or any subsequent Holder, as applicable, 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 less than the entire Warrant is transferred); and provided further, that any subsequent Holder shall agree in writing with the Company to be bound by all of the
