Warrant Price: $5.1123 per Share, subject to adjustment 

Issue Date: December 24, 2018 
 Expiration
Date: December 24, 2028                 See also Section 5.1(b).  

	Credit Facility:	 This Warrant to Purchase Stock (“Warrant”) is issued in connection with that certain
Credit Agreement of even date herewith among the Company as Borrower, Silicon Valley Bank as Administrative Agent and Lender, and the other Lenders from time to time parties thereto (as amended and/or modified and in effect from time to time, the
“Loan Agreement”). 


 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, HERCULES
CAPITAL, INC. (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 up to such number of fully paid and non-assessable shares of the above-stated Type/Series of Stock (the “Class”) of the above-named company (the “Company”) as determined pursuant to Paragraph A below, 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.     

A. Number of Shares. This Warrant shall be exercisable for the Initial Shares, plus the Additional Shares, if any (collectively, the
“Shares”). 
 (1) Initial Shares. As used herein, “Initial Shares” means 50,732 shares
of the Class, subject to adjustment from time to time in accordance with the provisions of this Warrant. 
 (2) Additional Shares.
Upon the making of each Term Loan Advance (as defined in the Loan Agreement) to the Company, this Warrant automatically shall become exercisable for such number of additional shares of the Class as shall equal (a) the Additional Shares
Pool, multiplied by (b) a fraction, the numerator of which shall equal the amount of such Term Loan Advance and the denominator of which shall equal $30,000,000, rounded to the nearest whole Share and subject to adjustment thereafter from time
to time in accordance with the provisions of this Warrant. All shares, if any, for which this Warrant becomes exercisable pursuant to this Paragraph A(2) are referred to herein cumulatively as the “Additional Shares.” 

(3) Additional Shares Pool. As used herein, “Additional Shares Pool” means 152,195 shares of the Class, as such
number may be adjusted from time to time in accordance with the provisions of this Warrant (as if the Additional Shares Pool constituted “Shares” at all times for such purpose). For the avoidance of doubt, in no event shall the aggregate
number of Shares for which this Warrant shall be exercisable exceed 202,927 (as such number may be adjusted from time to time in accordance with the provisions of this Warrant). 












 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. 

  
 2 













 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 (other than transfers for no consideration by one or more of such stockholders who are natural persons to
his or their respective family members, or to trusts established for the benefit of such family members, for estate planning purposes). 

(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 of 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. 

  
 3 













 (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 a 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. 

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. 

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, 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 

  
 4 













 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.
It is acknowledged that the Shares for which this Warrant may be exercised have certain rights under the Company’s Certificate of Incorporation, including conversion price adjustments for diluting issuances under certain circumstances, which
rights may be amended from time to time pursuant to the provisions of the Certificate of Incorporation. 
 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 Financial Officer, including computations of such adjustment and the Warrant Price, Class and number of Shares in effect
upon the date of such adjustment. 
 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 the
Class were last sold and issued prior to the Issue Date hereof in an arms-length transaction in which at least $500,000 of such shares were sold.     

(b) The number of Initial Shares first set forth above together with the number of shares constituting the Additional Shares Pool first set
forth above collectively represent not less than 0.110% of the Company’s total issued shares of capital stock, calculated on and as of the Issue Date hereof on a fully-diluted, common stock-equivalent basis assuming (i) the conversion into
common stock of all outstanding securities and instruments (including, without limitation, securities deemed to be outstanding pursuant to clause (ii) of this Section 3.1(b)) convertible by their terms into shares of common stock
(regardless of whether such securities or instruments are by their terms now so convertible), (ii) the exercise in full of all outstanding options, warrants (including, without limitation, this Warrant) and other rights to purchase or acquire shares
of common stock or securities exercisable for or convertible into shares of common stock (regardless of whether such options, warrants or other rights to purchase or acquire are by their terms now exercisable); and (iii) the inclusion of all
shares of common stock reserved for issuance under all of the Company’s incentive stock and stock option plans and not now subject to outstanding grants or options. 

  
 5 













 (c) 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 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. 

(d) 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 series of the Company’s stock (other than pursuant to contractual pre-emptive rights); 

(c) effect 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 as Holder may reasonably require regarding the treatment of this Warrant in connection with such event giving
rise to the notice); and 
 (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.     

  
 6 













 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. 
 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 2.11 of the Company’s Investor Rights Agreement, as amended and in effect from time to time, and the Company may place a
restrictive legend on any certificate representing any Shares issued on exercise hereof stating that they are subject to such provisions.     

  
 7 













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

5.1 Term; Automatic Cashless Exercise Upon Expiration.     

(a) Term. Subject to the provisions of Section 1.6 above, 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) for which it shall not previously have been
exercised, and the Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities) issued upon such exercise to Holder. 

5.2 Legends. Each certificate evidencing Shares (and each certificate evidencing securities issued upon conversion of any 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, EXCEPT AS SET FORTH IN THAT CERTAIN WARRANT TO PURCHASE STOCK ISSUED BY THE ISSUER TO HERCULES CAPITAL, INC. DATED
DECEMBER 24, 2018, 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
issued 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 except in 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 an affiliate of Holder, provided that such affiliate 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 and upon providing the Company with written notice, Holder may
transfer all or part of this Warrant or the Shares issued upon exercise of this Warrant (or the securities issued upon conversion of the Shares, if any) to any transferee, 

  
 8 













 provided, however, in connection with any such transfer, 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 transferee shall agree in writing with the Company to be bound by all of the terms and conditions of this Warrant. 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. 

5.5 Notices. All notices and other communications hereunder from the Company to the Holder, or vice versa, shall be deemed delivered
