(“Oxford”)] [SILICON VALLEY BANK] (together with any successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid
and non-assessable shares (the “Shares”) of the above-stated Type/Series of Stock (the “Class”) of the above-named company (the “Company”) at the above-stated Warrant Price, all as set forth above
and as adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. [Reference is made to Section 5.4 of this Warrant whereby Silicon Valley Bank shall transfer this

 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;


  
 1 









			
		
	Y =	  	the number of Shares with respect to which this Warrant is being exercised (inclusive of the Shares surrendered to the Company in payment of the aggregate Warrant
Price);
		
	A =	  	the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and
		
	B =	  	the Warrant Price.

 1.3 Fair Market Value. If the Company’s common stock is then traded or quoted on a nationally
recognized securities exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”) and the Class is common stock, the fair market value of a Share shall be the closing price or last sale price of a share
of common stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the Company. If the Company’s common stock is then traded in a Trading Market and the Class
is a series of the Company’s convertible preferred stock, the fair market value of a Share shall be the closing price or last sale price of a share of the Company’s common stock reported for the Business Day immediately before the date on
which Holder delivers this Warrant together with its Notice of Exercise to the Company multiplied by the number of shares of the Company’s common stock into which a Share is then convertible. If the Company’s common stock is not traded in
a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in its reasonable good faith judgment. 
 1.4 Delivery of Certificate and New Warrant. Within a reasonable time after Holder exercises this Warrant in the manner set forth in Section 1.1 or 1.2 above, the Company shall deliver to
Holder a certificate representing the Shares issued to Holder upon such exercise and, if this Warrant has not been fully exercised and has not expired, a new warrant of like tenor representing the Shares not so acquired. 

1.5 Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the
Company for cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount. 
 1.6 Treatment of Warrant Upon Acquisition of Company. 
 (a) Acquisition.
For the purpose of this Warrant, “Acquisition” means any transaction or series of related transactions involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the
Company (ii) any merger or consolidation of the Company into or with another person or entity (other than a merger or consolidation effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the
stockholders of the Company in their capacity as such immediately 

  
 2 








 
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. 

(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”), either (i) Holder shall exercise this Warrant pursuant to Section 1.1
and/or 1.2 and such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Acquisition or (ii) if Holder elects not to exercise the Warrant, this Warrant will expire immediately prior to the
consummation of such Acquisition. 
 (c) The Company shall provide Holder with written notice of its request relating to the
Cash/Public Acquisition (together with such reasonable information as Holder may reasonably require regarding the treatment of this Warrant in connection with such contemplated Cash/Public Acquisition giving rise to such notice), which is to be
delivered to Holder not less than seven (7) Business Days prior to the closing of the proposed Cash/Public Acquisition. In the event the Company does not provide such notice, then if, immediately prior to the Cash/Public Acquisition, the fair
market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above would be 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 promptly notify the Holder of the number of Shares (or
such other securities) issued upon such exercise to the Holder and Holder shall be deemed to have restated each of the representations and warranties in Section 4 of the Warrant as the date thereof. 

(d) Upon the closing of any Acquisition other than a Cash/Public Acquisition defined above, 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. 

(e) As used in this Warrant, “Marketable Securities” means securities meeting all of the following requirements:
(i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all
required reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were Holder to exercise this
Warrant on or prior to the closing thereof is then traded in Trading Market, and (iii) Holder would be able to publicly re-sell, within six (6) months following the closing of such Acquisition, 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.

 1.7 Adjustment to Class of Shares; Number of Shares; Warrant Price; Adjustments
Cumulative. In the event of a preferred stock equity financing by the Company after the Issue Date the gross proceeds of which equal at least Five Million Dollars ($5,000,000) (the “Next Round”), if the price per share (the
“Next Round Price”) of such shares of preferred stock (the “Next Round Stock”) is less than the Warrant Price, Holder shall have the right, in Holder’s sole discretion, to elect to treat all of this Warrant as
exercisable for Shares of the Next Round Stock at the Next Round Price (with the number of such shares subject of this Warrant automatically adjusted to equal (i) the aggregate Number of Shares for which this Warrant is then exercisable (as
adjusted hereunder, but before giving effect to this Section 1.7) multiplied by (ii) the quotient of (x) the Warrant Price divided by (y) the Next Round Price) (the “Next Round Election”). Company shall provide Holder
no less than fifteen (15) Business Days’ written notice prior to any sale of Next Round Stock (the “Next Round Notice”). Holder shall make the Next Round Election by providing the Company with written notice within ten
(10) Business Days’ of its receipt of the Next Round Notice (the “Next Round Election Period”) and Holder shall be deemed to waive it right to make such Next Round Election if it fails to deliver its Next Round Election within
the Next Round Election Period. If Holder makes the Next Round Election within the Next Round Election Period, then (a) the Next Round Election shall be effective immediately following the initial closing of the Next Round and (b) the
Shares for which this Warrant is exercisable shall bear the same rights, preferences, and privileges of such Next Round Stock. The right of Holder to make a Next Round Election (and the corresponding adjustment provided for in this Section 1.7)
shall (i) only apply to the first Next Round that occurs after the Issue Date and shall not apply to any other financing and (ii) shall terminate (x), in the case of the occurrence of an Acquisition, then upon the satisfaction of the
provisions of Section 1.6 hereof and (y) in the case of the occurrence of an IPO (defined below), then upon the satisfaction of Section 2.3 hereof. Any adjustment to the Class of Shares, Number of Shares and/or Warrant Price made as a
result of this Article 1.7 shall be in addition to any adjustment(s) to be made in accordance with Article 2 hereof. 
 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. 

  
 4 








 2.3 Conversion of Preferred Stock. If the Class is a class and series of the
Company’s convertible preferred stock, in the event that all outstanding shares of the Class are converted, automatically or by action of the holders thereof, into common stock pursuant to the provisions of the Company’s Certificate of
Incorporation, as such may be amended from time to time (the “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
of common stock into which the Shares would have been converted had the Shares been outstanding on the date of such conversion, and the Warrant Price shall equal the Warrant Price in effect as of immediately prior to such conversion divided by the
number of shares of common stock into which one Share would have been converted, all subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant. 

2.4 Adjustments for Diluting Issuances. Without duplication of any adjustment otherwise provided for in this Section 2, the
number of shares of common stock issuable upon conversion of the Shares shall be subject to anti-dilution adjustment from time to time in the manner set forth in the Company’s Certificate of Incorporation as if the Shares were issued and
outstanding on and as of the date of any such required adjustment. 
 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.
