 THIS WARRANT CERTIFIES THAT, for other good and valuable consideration,
                    (‘‘Holder’’) is entitled to purchase the number of fully paid and nonassessable shares of the class of
securities (the “Shares”) of the Company at 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 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. If the Company’s common stock is traded in a public market and the Shares
are common stock, the fair market value of each Share shall be the closing price of a Share reported for the business day immediately before Holder delivers its Notice of Exercise to the Company (or in the instance where the Warrant is exercised
immediately prior to the effectiveness of the Company’s initial public offering, the “price to public” per share price specified in the final prospectus relating to such offering). If the Company’s common stock is traded in a
public market and the Shares are preferred stock, the fair market value of a Share shall be the closing price of a share of the Company’s common stock reported for the business day immediately before Holder delivers its Notice of Exercise to
the Company (or, in the instance 

 
where the Warrant is exercised immediately prior to the effectiveness of the Company’s initial public offering, the initial “price to public” per share price specified in the final
prospectus relating to such offering), in both cases, multiplied by the number of shares of the Company’s common stock into which a Share is convertible. If the Company’s common stock is not traded in a public market, the Board of
Directors of the Company shall determine the fair market value of the Shares in its reasonable good faith judgment. 
 1.4.
Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant and, if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares
acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired. 
 1.5. Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or
destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation on surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this Warrant,
a new warrant of like tenor. 
 1.6. Treatment of Warrant Upon Acquisition of Company. 

1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale, 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. 
 1.6.2 Treatment of Warrant at
Acquisition. 
 A) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that is not
an asset sale and 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 written request of the Company, Holder agrees that, in the event of an Acquisition that is an “arms
length” sale of all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”), either (a) Holder shall exercise its
conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will continue until the
Expiration Date if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the Holder with written notice of its request relating to the foregoing (together with such reasonable
information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition. 

  
 2 

 C) Upon the closing of any Acquisition other than those particularly described in
subsections (A) and (B) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall automatically and without further action 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. 
 As used herein “Affiliate” shall mean any person or entity that owns or controls directly or
indirectly ten (10) percent or more of the stock of Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers, directors,
joint venturers or partners, as applicable. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 

2.1. Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares 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 Shares by reclassification or otherwise into a greater number of shares or takes any other action which increase the amount of stock into which the Shares are convertible, the number of
shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. 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 and the number of Shares shall be proportionately decreased. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Article 2.1 for an event that results in an adjustment pursuant
to Article 2.2 or 2.3 hereof. 
 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 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 an amendment to this Warrant setting forth the number and kind of such new securities or other property issuable upon exercise
or conversion of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of securities issuable upon exercise or conversion of this Warrant. The amendment to this
Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. Notwithstanding the foregoing, no adjustment shall be made
pursuant to this Article 2.2 for an event that results in an adjustment pursuant to Article 2.1 or 2.3 hereof. 
 2.3.
Adjustments for Diluting Issuances. The Warrant Price and the number of Shares issuable upon exercise of this Warrant or, if the Shares are preferred stock, the number of shares of common stock issuable upon conversion of the Shares, shall be
subject to adjustment, from 

  
 3 

 
time to time in the manner set forth in the Company’s Certificate of Incorporation as if the Shares were issued and outstanding on and as of the date of any such required adjustment. The
provisions set forth for the Shares in the Company’s Certificate (as applicable) of Incorporation 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. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Article 2.3 for an event that results in an adjustment pursuant to Article 2.1 or 2.2 hereof. 

2.4. No Impairment. The Company shall not, by amendment of its Articles or Certificate (as applicable) 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. 
 2.5. Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion 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 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, 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 Executive
Officer, Chief Financial Officer or any other duly authorized officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant
Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 
 ARTICLE 3. REPRESENTATIONS AND
COVENANTS OF THE COMPANY. 
 3.1. Representations and Warranties. The Company represents and warrants to the Holder
as follows: 
 (a) The initial Warrant Price referenced on the first page of this Warrant is not greater than (i) the price
per share at which the Shares were last issued in an arms-length transaction in which at least $500,000 of the Shares were sold. 
 (b) All Shares which may be issued upon the exercise of the purchase right represented by this Warrant, and all securities, if any, issuable upon conversion of the Shares, shall, upon issuance, 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. 

(c) The Capitalization Table previously provided to Holder remains true and complete as of the Issue Date. 

3.2. Notice of Certain Events. If the Company proposes at any time (a) to declare any dividend or distribution upon any of
its stock, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; (b) to offer for sale any shares of the Company’s 

  
 4 

 
capital stock (or other securities convertible into such capital stock) of the same class as the class of Stock of the Shares issuable upon exercise of this Warrant, other than (i) pursuant
to the Company’s stock option or other compensatory plans, (ii) in connection with commercial credit arrangements or equipment financings, or (iii) in connection with strategic transactions for purposes other than capital raising;
(c) to offer for sale any shares of the Company’s capital stock (or other securities convertible into such capital stock) other than shares of the same class as the class of Stock of the Shares issuable upon exercise of this Warrant, other
than (i) pursuant to the Company’s stock option or other compensatory plans, (ii) in connection with commercial credit arrangements or equipment financings, or (iii) in connection with strategic transactions for purposes other
than capital raising; (d) to effect any reclassification or recapitalization of any of its stock; (e) to merge or consolidate with or into any other corporation, or sell, lease, license, or convey all or substantially all of its assets, or
to liquidate, dissolve or wind up; or (f) offer holders of registration rights the opportunity to participate in an underwritten public offering of the Company’s securities for cash, then, in connection with each such event, the Company
shall give Holder: (1) at least 10 days prior written notice of the date on which a record will be taken for such dividend, distribution, or subscription rights (and specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters referred to in (a) and (b) above; (2) in the case of the matter referred to in (c) above, written notice within 10 days after the date on which a
record was taken for such subscription rights; (3) in the case of the matters referred to in (d) and (e) above at least 10 days prior written notice of the date when the same will take place (and specifying the date on which the
holders of common stock will be entitled to exchange their common stock for securities or other property deliverable upon the occurrence of such event); and (4) in the case of the matter referred to in (1) above, the same notice as is
given to the holders of such registration rights. 
 3.3. Registration Under Securities Act of 1933, as amended. The
Company agrees that the Shares or, if the Shares are convertible into common stock of the Company, such common stock, shall have certain incidental, or “Piggyback,” registration rights and “S-3” registration rights as set forth
in the Company’s Investor Rights Agreement or similar agreement. The provisions set forth in the Investors’ Right Agreement or similar agreement 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 Stockholder Rights. Except as provided in
this Warrant, the Holder will not have any rights as a stockholder 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 the Holder will be acquired for investment for the 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 the Holder has not been formed for the specific purpose of acquiring this Warrant or the Shares. 

4.2. Disclosure of Information. The 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. The 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 

  
 5 

 
without unreasonable effort or expense) necessary to verify any information furnished to the Holder or to which the Holder has access. 

4.3. Investment Experience. The Holder understands that the purchase of this Warrant and its underlying securities involves
substantial risk. The Holder has experience as an investor in securities of companies in the development stage and acknowledges that the 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 the 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 the Holder to be aware of the character, business acumen and financial circumstances of such persons. 

4.4. Accredited Investor Status. The Holder is an “accredited investor” within the meaning of Regulation D promulgated
under the Act. 
 4.5. The Act. The 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. The 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. Market Stand-Off. The Holder and any permitted transferee
hereby agrees to be bound by the “Market Stand-Off” provisions (the “Market Stand-Off Provisions”) contained in the Company’s Investor Rights Agreement (the “Rights Agreement”) dated
            , which are incorporated by reference into this Warrant and deemed to be a part hereof. The Market Stand-Off Provisions set forth in the Rights Agreement 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 all other shares of the same series and class as of the Shares granted pursuant to this
Warrant. 
 ARTICLE 5. MISCELLANEOUS. 
 5.1. Term: This Warrant is exercisable in whole or in part at any time and from time to time on or before the Expiration Date. 

5.2. Legends. This Warrant and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if
any) shall be imprinted with a legend in substantially the following form: 
 THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 BELOW, 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,

  
 6 

 
SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS EXEMPT FROM REGISTRATION. 
 5.3. Compliance with Securities Laws on Transfer. This Warrant and the Shares issuable upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion of the
Shares, if any) may not be transferred or assigned in whole or in part without compliance with applicable federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment
representation letters and legal Opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to Holder’s parent company, SVB
Financial Group (formerly Silicon Valley Bancshares), or any other affiliate of Holder. Additionally, the Company shall also not require an opinion of counsel if there is no material question as to the availability of current information as
referenced in Rule 144(c), Holder represents that it has complied with Rule 144(d) and (e) in reasonable detail, the selling broker represents that it has complied with Rule 144(f), and the Company is provided with a copy of Holder’s
notice of proposed sale, provided that any such representation is acceptable to the Company in the Company’s reasonable good faith discretion. 
 5.4. Transfer Procedure. Upon receipt by Holder of the executed Warrant, Holder 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). The Company may refuse to transfer this Warrant or the Shares to any person who directly competes with the Company, unless, in either case, the stock of the Company is publicly traded. 

5.5. Notices. All notices and other communications from the Company to the Holder, or vice versa, shall be deemed delivered and
effective when given personally or mailed by first-class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company or the Holder, as the case may (or on the first business day after transmission by
facsimile) be, in writing by the Company or such Holder from time to time. Effective upon receipt of the fully executed Warrant and the initial transfer described in Article 5.4 above, all notices to the Holder shall be addressed as follows until
the Company receives notice of a change of address in connection with a transfer or otherwise:

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 the Holder.

	Issue Date:	  	July 30, 2008

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, GOLD HILL VENTURE LENDING 03, LP (Gold
Hill Venture Lending 03, LP, together with any registered holder from time to time of this Warrant or any holder of the shares issuable or issued upon exercise of this Warrant, “Holder”) is entitled to purchase the number of
fully paid and nonassessable shares of the class of securities (the “Shares”) of the Company at 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 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 (or, if only a portion of the Warrant is being converted, the aggregate fair market value of the portion of the Warrant being converted) minus the aggregate Warrant
Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to Article 1.3. 

 1.3. Fair Market Value. If the Company’s common stock is traded in a public
market and the Shares are common stock, the fair market value of each Share shall be the closing price of a Share reported for the business day immediately before Holder delivers its Notice of Exercise to the Company (or in the instance where the
Warrant is exercised immediately prior to the effectiveness of the Company’s initial public offering, the “price to public” per share price specified in the final prospectus relating to such offering). If the Company’s common
stock is traded in a public market and the Shares are preferred stock, the fair market value of a Share shall be the closing price of a share of the Company’s common stock reported for the business day immediately before Holder delivers its
Notice of Exercise to the Company (or, in the instance where the Warrant Is exercised immediately prior to the effectiveness of the Company’s initial public offering, the initial “price to public” per share price specified in the
final prospectus relating to such offering), in both cases, multiplied by the number of shares of the Company’s common stock into which a Share is convertible. If the Company’s common stock is not traded in a public market, the Board of
Directors of the Company shall determine fair market value in its reasonable good faith judgment. 
 1.4. Delivery of
Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant and, if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and,
if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired. 
 1.5. Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or
destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation or 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, 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. 
 1.6.2 Treatment of Warrant at
Acquisition. 
 (A) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that is
not an asset sale and 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 does not exercise the Warrant prior to or in connection with the consummation of such Acquisition, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide Holder with
written notice of its request relating to the foregoing (together with such reasonable information as Holder may request in connection with such contemplated Acquisition giving rise to 

  
 2 

 
such notice), which Is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition. 

(B) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that Is an “arms length”
safe of all or substantially all of the Company’s assets (and only Its assets) to a third party that Is not an Affiliate (as defined below) of the Company (a “True Asset Sale”), either (a) Holder shall exercise its conversion or
purchase right under this Warrant and such exercise will be deemed effective Immediately prior to the consummation of such True Asset Safe or (b) if Holder does not exercise the Warrant prior to or in connection with the consummation of such
True Asset Sale, this Warrant will continue until the Expiration Date if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide Holder with written notice of Its request relating to the
foregoing (together with such reasonable information as 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. 
 (C) Upon the written request of the Company, Holder agrees that, in the event of a stock for stock
Acquisition of the Company by a publicly traded acquirer if, on the record date for the Acquisition, the fair market value of the Shares (or other securities issuable upon exercise of this Warrant) Is equal to or greater than three
(3) times the Warrant Price, the Company may require the Warrant to be deemed automatically exercised and the Holder shall participate in the Acquisition as a holder of the Shares (or other securities Issuable upon exercise of the Warrant) on
the same terms as other holders of the same class of securities of the Company. 
 (D) Upon the closing of any Acquisition other
than those particularly described in subsections (A), (B) and (C) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be
payable for the Shares Issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Shares shall be adjusted
accordingly. 
 As used herein “Affiliate” shall mean any person or entity that owns or controls directly or
indirectly ten (10) percent or more of the stock of Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers,
directors, joint venturers or partners, as applicable. 
 For purposes of clarification, nothing contained in this Article 1.6,
shall require the separate consent of the Holder for any Acquisition. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 

2.1. Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares 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 Shares by reclassification or otherwise into a greater number of shares or takes any other action which increases the amount of stock into which the 

  
 3 

 Shares are convertible, the number of shares purchasable hereunder shall be proportionately
increased and the Warrant Price shall be proportionately decreased. 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 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 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 Articles or Certificate (as
applicable) 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 an amendment to this Warrant setting forth the number and kind of such new
securities or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of securities issuable upon exercise or
conversion of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 

2.3. Adjustments for Diluting Issuances. The Warrant Price and the number of Shares issuable upon exercise of this Warrant or, if
the Shares are preferred stock, the number of shares of common stock issuable upon conversion of the Shares, shall be subject to adjustment, from time to time in the manner set forth in the Company’s Articles or Certificate of Incorporation as
if the Shares were issued and outstanding on and as of the date of any such required adjustment. The provisions set forth for the Shares in the Company’s Articles or Certificate (as applicable) of Incorporation 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 Holder. 

2.4. No Impairment. The Company shall not, by amendment of its Articles or Certificate (as applicable) 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. 

  
 4 

 2.5. Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion 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 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, the Company shall provide Holder with a Certificate of Adjustment pursuant to Article IV, Section D.5(j) of the
Company’s Certificate of Incorporation.

series and class as the Shares granted to Holder.
