VAIL HOLDCO CORP 

WARRANT TO PURCHASE COMMON STOCK 
  

					
	Warrant No. [●]	  		  	[●], 20[●] (the “Issue Date”)

 Vail Holdco Corp, a Delaware corporation (the “Company”), for value received, certifies and
agrees, subject to the terms and conditions set forth in this warrant (this warrant and any other warrants delivered in substitution or exchange herefor as provided herein, this “Warrant”) that [●], a [●] (the
“Holder”), is entitled, subject to the terms set forth below, to purchase from the Company [●] duly authorized, validly issued, fully paid and nonassessable shares of Common Stock (such shares, subject to adjustment as
provided herein, the “Warrant Shares”) at a price of $0.01 per Warrant Share (the “Exercise Price”). Except as otherwise defined herein, capitalized terms in this Warrant have the meanings set forth in
Section 21. This Warrant has been issued pursuant to the terms of the Series A Purchase Agreement. 

1.    Term. Subject to the terms and conditions hereof, the Holder may exercise this Warrant for all or any part of
the Warrant Shares at any time or from time to time after the Issue Date and prior to 5:00 p.m., New York City time, on the Expiration Date (the “Exercise Period”). 

2.    Exercise. 

2.1    Method of Exercise. This Warrant may be exercised by the Holder, in whole or in part: 

(a)    by surrendering (i) this Warrant and (ii) a duly executed Notice of Exercise in the form
of Exhibit A attached hereto (the “Notice of Exercise”) to the Company (or its agent) via delivery in accordance with Section 16; and 

 (b)    by: 

(i)    paying to the Company the Aggregate Exercise Price by wire transfer of immediately available funds
to an account designated in writing by the Company; or 
 (ii)    instructing the Company to withhold a
number of Warrant Shares then issuable upon exercise of this Warrant with an aggregate Fair Market Value as of the Exercise Date equal to such Aggregate Exercise Price (and the Company shall comply with Section 2.5 with
respect to any fractional shares of Common Stock otherwise issuable as a result). 
 2.2    Automatic
Exercise. This Warrant shall be deemed to have been exercised pursuant to Section 2.1(b)(ii) automatically, and without requiring any further action on the part of the Holder, immediately prior to expiration hereof on
the Expiration Date in the case of an Expiration Date pursuant to clause (c) of the definition thereof (and, for the avoidance of doubt, after giving effect to any adjustment pursuant to Section 4.1 as a result of the
issuance of shares of Common Stock pursuant to the Advisory Agreement). 
 2.3    Exercise Date.
Each exercise of this Warrant will be deemed to have been effected immediately prior to the close of business on the day (a) on which the Notice of Exercise is deemed to be delivered pursuant to Section 16 to the
Company as provided in Section 2.1(a) and payment has been made as provided in Section 2.1(b) or (b) if a later date is specified in the Notice of Exercise, such later date (each such date, an
“Exercise Date”). At such time, each Person in whose name any certificates for Warrant Shares are issuable upon such exercise as provided in Section 2.4 will become a holder of record of the Warrant Shares
represented by such certificates and will become (if such holder is not already) a Stockholder (as defined in the Stockholders Agreement) with respect to such Warrant Shares. 

2.4    Certificates and New Warrants. As soon as practicable after an Exercise Date (and in any
event within five (5) Business Days thereafter), the Company, at its expense, will cause to be issued in the name of, and delivered to, the Holder, or as the Holder may direct (subject to Section 5): 

(a)    a certificate or certificates for the number of shares of Common Stock to which the Holder is
entitled upon such exercise (it being agreed that each certificate so delivered will be in such denominations of shares of Common Stock as may be requested by the Holder but in no event in fractional shares); and 

(b)    if such exercise is in part only, a new Warrant or Warrants substantially identical in form hereto
for the purchase of a number of Warrant Shares equal to the difference of the number of Warrant Shares subject to this Warrant less the number of Warrant Shares that are the subject of such partial exercise. 

2.5    No Fractional Shares. No fractional shares of Common Stock shall be issued upon the exercise
of this Warrant. As to any fraction of a share of Common Stock which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an
amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share of Common Stock. 

  
 -2- 

 2.6    Conditional Exercise. Notwithstanding the
foregoing and subject to Section 4.5, if an exercise of any portion of this Warrant is to be made in connection with a public offering (including a Qualified IPO) or a Change of Control (pursuant to a merger, sale of stock,
or otherwise), such exercise may at the election of the Holder be conditioned upon the consummation of such transaction, in which case the Exercise Date will be the date of such consummation and such exercise will not be deemed to be effective until
immediately prior to such consummation on the Exercise Date (provided, for the avoidance of doubt, such exercise shall not be deemed effective until after giving effect to any adjustment pursuant to Section 4.1 as a
result of the issuance of shares of Common Stock pursuant to the Advisory Agreement). 
 3.    Shares to be Fully
Paid; Reservation of Shares. The Company represents, warrants, covenants and agrees that: 

(a)    this Warrant is, and any Warrant issued in substitution for or replacement of this Warrant will be,
upon issuance, duly authorized and validly issued; 
 (b)    all Warrant Shares issued upon the exercise
of this Warrant will, upon issuance, be validly issued, fully paid and nonassessable, and free from preemptive rights, liens and charges, other than liens and charges arising solely from the actions and circumstances of the Holder or holder of such
Warrant Shares; 
 (c)    during the Exercise Period, the Company will at all times have authorized, and
reserved, free from preemptive rights and solely for the purpose of effecting the exercise of this Warrant, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to provide for the exercise of the rights
represented by this Warrant, which shares have not been subscribed for or otherwise committed to be issued; 

(d)    during the Exercise Period, the Company will take all such action as may be necessary to ensure that
the par value per Warrant Share will at all times be less than or equal to the applicable Exercise Price; 

(e)    during the Exercise Period, the Company will take all such actions as may be necessary to ensure
that all such Warrant Shares are issued without violation by the Company of any applicable Law or any requirements of any securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares may be listed at the time
of such exercise (except for official notice of issuance which will be immediately delivered by the Company upon each such issuance); 

(f)    the Company will use its reasonable best efforts to cause the Warrant Shares, immediately upon such
exercise, to be listed on any securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares are listed at the time of such exercise; and 

(g)    the Company will pay all expenses in connection with, and all documentary, stamp or similar issue or
transfer taxes due on the issuance or delivery of Warrant Shares upon exercise of this Warrant; provided, however, that, if such documentary, stamp or similar issue or transfer tax is due because the Holder has requested that the
Warrant Shares be issued in a name other than that of the Holder, then such taxes shall be paid by such Holder, and the Company shall not be required to issue or deliver any stock certificate representing the Warrant Shares unless and until such
Holder shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 

  
 -3- 

 4.    Adjustment. The number of Warrant Shares issuable upon
exercise of this Warrant will be subject to adjustment from time to time as set forth in this Section 4. 

4.1    Adjustment to Number of Warrant Shares Upon Issuance of Common Stock. Except (x) for an
issuance or sale of Common Stock for which an adjustment was previously made under this Section 4.1 and Section 4.2 upon the deemed issuance or sale of Options or Convertible Securities providing
for the right to purchase such Common Stock or convert such Convertible Securities into such Common Stock (other than any further adjustment under Section 4.2(c)), (y) for an Issuance of Excluded Securities or (z) in
the case of an event described in either Section 4.3 or Section 4.4, if the Company, at any time after the issuance of this Warrant, issues or sells, or in accordance with
Section 4.2 is deemed to have issued or sold, any shares of Common Stock without consideration (including any shares issued in connection with the Advisory Agreement) or for consideration per share less than the Fair Market
Value per share of Common Stock in effect immediately prior to such Issuance, then immediately upon such Issuance, the number of Warrant Shares issuable upon the exercise of this Warrant immediately prior to any such Issuance shall be increased to a
number of Warrant Shares equal to the product obtained by multiplying the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such Issuance by the quotient of: 

(a)    the Outstanding Common Stock immediately after such Issuance divided by, 

(b)    the sum of (i) the Outstanding Common Stock immediately prior to such Issuance plus
(ii) the aggregate number of shares of Common Stock which the aggregate amount of consideration, if any, received by the Company upon such Issuance would purchase at the Fair Market Value per share of Common Stock in effect immediately prior to
such Issuance. 
 4.2    Deemed Issuances. The following will apply for purposes of determining
the adjusted number of Warrant Shares under Section 4.1, other than with respect to Excluded Securities: 

(a)    Issuance of Options. If the Company, at any time after the issuance of this Warrant, in any
manner grants or sells (whether directly or by assumption in a merger or otherwise) any Options, whether or not such Options or the right to convert or exchange any Convertible Securities issuable upon the exercise of such Options are immediately
exercisable, and the price per share (determined as provided in this Section 4.2(a) and in Section 4.2(e)) for which Common Stock is issuable upon the exercise of such Options or upon the
conversion or exchange of Convertible Securities issuable upon the exercise of such Options is less than the Fair Market Value per share of Common Stock in effect immediately prior to the time of the granting or sale of such Options, then the total
maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of Convertible Securities issuable upon the exercise of such Options will be deemed to have been issued as
of the date of granting or sale of such Options, at a price per share equal to the quotient of: 

(i)    the sum (which sum will be the applicable consideration received by the Company for purposes of
Section 4.1) of (A) the total amount, if any, received or receivable by the Company as consideration for the granting or sale of all such Options, plus (B) the minimum aggregate amount of additional
consideration 

  
 -4- 

 
payable to the Company upon the exercise of all such Options, plus (C) in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the issuance or sale of all such Convertible Securities and the conversion or exchange of all such Convertible Securities divided by, 

(ii)    the total maximum number of shares of Common Stock issuable upon the exercise of all such Options
or upon the conversion or exchange of all Convertible Securities issuable upon the exercise of all such Options. 
 Except as otherwise
provided in Section 4.2(c), no further adjustment of the number of Warrant Shares will be made upon the actual issuance of Common Stock or Convertible Securities upon exercise of such Options or upon the actual issuance of
Common Stock upon conversion or exchange of the Convertible Securities issuable upon exercise of such Options. 

(b)    Issuance of Convertible Securities. If the Company, at any time after the issuance of this
Warrant, in any manner grants or sells (whether directly or by assumption in a merger or otherwise) any Convertible Securities, whether or not the right to convert or exchange any such Convertible Securities is immediately exercisable, and the price
per share (determined as provided in this Section 4.2(b) and in Section 4.2(e)) for which Common Stock is issuable upon the conversion or exchange of such Convertible Securities is less than the
Fair Market Value per share of Common Stock in effect immediately prior to the time of the granting or sale of such Convertible Securities, then, unless an adjustment under Section 4.1(a) has already been made, the total
maximum number of shares of Common Stock issuable upon conversion or exchange of the total maximum amount of such Convertible Securities will be deemed to have been issued as of the date of granting or sale of such Convertible Securities, at a price
per share equal to the quotient of: 
 (i)    the sum (which sum will constitute the applicable
consideration received by the Company for purposes of Section 4.1) of (A) the total amount, if any, received or receivable by the Company as consideration for the granting or sale of such Convertible Securities,
plus (B) the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange of all such Convertible Securities divided by, 

(ii)    the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible Securities. 
 Except as otherwise provided in Section 4.2(c), no further adjustment of the number
of Warrant Shares will be made upon the actual issuance of Common Stock upon conversion or exchange of such Convertible Securities or by reason of the issuance or sale of Convertible Securities upon exercise of any Options to purchase any such
Convertible Securities for which adjustments of the number of Warrant Shares have been made pursuant to Section 4.2(a). 

(c)    Change in Terms of Options or Convertible Securities. Upon any change in any of (i) the
total amount received or receivable by the Company as consideration for the granting or sale of any Options or Convertible Securities referred to in Section 4.2(a) or Section 4.2(b), (ii) the
minimum aggregate amount of additional consideration, if any, 

  
 -5- 

 
payable to the Company upon the exercise of any Options referred to in Section 4.2(a) or upon the issuance, conversion or exchange of any Convertible Securities referred
to in Section 4.2(a) or Section 4.2(b), (iii) the rate at which Convertible Securities referred to in Section 4.2(a) or Section 4.2(b) are
convertible into or exchangeable for Common Stock or (iv) the maximum number of shares of Common Stock issuable in connection with any Options referred to in Section 4.2(a) or any Convertible Securities referred to in
Section 4.2(a) or Section 4.2(b) (in each case, other than in connection with an Issuance of Excluded Securities), then (regardless of whether the original issuance or sale of such Options or
Convertible Securities resulted in an adjustment to the number of Warrant Shares issuable upon exercise of this Warrant pursuant to this Section 4) the number of Warrant Shares issuable upon exercise of
this Warrant at the time of such change will be adjusted or readjusted, to the extent applicable, to the number of Warrant Shares issuable upon exercise of this Warrant which would have been in effect at such time pursuant
to the provisions of this Section 4 had such Options or Convertible Securities provided for such changed consideration, conversion rate or maximum number of shares, as the case may be, at the time initially granted, issued
or sold, but only if as a result of such adjustment or readjustment, the number of Warrant Shares issuable upon the exercise of this Warrant is increased. 

(d)    Expired or Terminated Options or Convertible Securities. Upon the expiration or termination
of any unexercised Option (or portion thereof) or any unconverted or unexchanged Convertible Security (or portion thereof) for which any adjustment (either upon its original issuance or upon a revision of its terms) was made pursuant to this
Section 4, the number of Warrant Shares then issuable upon exercise of this Warrant shall be recomputed immediately upon such expiration or termination pursuant to the provisions of this Section 4
to the number of Warrant Shares issuable upon exercise of this Warrant which would have been in effect at the time of such expiration or termination had such unexercised Option (or portion thereof) or unconverted or unexchanged Convertible
Security (or portion thereof), to the extent outstanding immediately prior to such expiration or termination, never been issued. 

(e)    Calculation of Consideration Received. If the Company, at any time after the issuance of this
Warrant, issues or sells, or is deemed to have issued or sold in accordance with this Section 4.2, any shares of Common Stock, Options or Convertible Securities (i) for cash, the consideration received therefor will be
the amount in cash received by the Company therefor, (ii) for consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration
is marketable securities, in which case the amount of consideration received by the Company will be the market price (as reflected on any securities exchange, quotation system or association or similar pricing system covering such security) for such
securities as of the end of business on the trading day immediately prior to the date of receipt of such securities, (iii) for no specifically allocated consideration in connection with an issuance or sale of other securities of the Company
that together comprises one integrated transaction, the amount of the consideration therefor will be deemed to be zero or (iv) to the owners of the nonsurviving entity in connection with any merger in which the Company is the surviving
corporation, the amount of consideration therefor will be deemed to be the fair value of the net assets and business of the nonsurviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be,
issued to such owners. The net amount of any cash consideration and the fair value of any consideration other than cash or marketable securities will be jointly determined in good faith by the Board and the Holder. 

  
 -6- 

 (f)    Record Date. For purposes of any
adjustment to the number of Warrant Shares in accordance with this Section 4, if the Company fixes a record date (or a record date will otherwise occur) prior to the Expiration Date for the purpose of entitling its holders
of Common Stock to (i) receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be
deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or
purchase, as the case may be. 
 (g)    Par Value. Notwithstanding anything to the contrary
herein, if, despite the Company’s obligations under Section 3(d), the Exercise Price at any time is less than the par value of the Warrant Share, the Holder will be entitled to pay the par value as the Exercise Price.
This Section 4.2(g) will not affect the Company’s obligations under Section 3(d). 

4.3    Stock Dividends, Stock Splits, Subdivisions, Reclassifications or Combinations. 

(a)    If the Company (i) declares and pays a dividend or makes a distribution on its Common Stock or
any other capital stock of the Company payable in shares of additional Common Stock or in Options or Convertible Securities, (ii) subdivides (by stock split or otherwise) or reclassifies the outstanding Common Stock into a greater number of
shares, or (iii) issues Common Stock upon the conversion of Class B Stock in accordance with Article 4.G of the Certificate of Incorporation, the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to any such
dividend, distribution or subdivision will be proportionately increased. 
 (b)    If the Company
combines or reclassifies (by reverse stock split or otherwise) the outstanding Common Stock into a smaller number of shares, then the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such combination will be
proportionately decreased. 
 (c)    Any adjustment under this Section 4.3 will
become effective at the close of business on the record date of any such dividend or distribution or the effective date of any such subdivision, reclassification or combination, as the case may be. 

4.4    Business Combination.  

(a)    In the event of any Business Combination, in each case which entitles the holders of Common Stock to
receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, (i) each Warrant will, immediately after such Business Combination, remain outstanding and thereafter, in lieu
of or in addition to (as the case may be) the number of Warrant Shares then issuable upon exercise of this Warrant, be exercisable for the kind and number of shares of stock or other securities or assets of the Company or of the successor Person
resulting from such Business Combination to which the Holder would have been entitled upon such Business Combination if the Holder had exercised this Warrant in full 

  
 -7- 

 
immediately prior to the time of such Business Combination and acquired the applicable number of Warrant Shares then issuable hereunder as a result of such exercise (without taking into account
any limitations or restrictions on the exercisability of this Warrant) and (ii) in such case, appropriate adjustment (in form and substance satisfactory to the Holder) will be made with respect to the Holder’s rights under this Warrant to
ensure that the provisions of this Section 4 are thereafter applicable, as nearly as possible, to this Warrant in relation to any shares of stock, securities or assets thereafter acquirable upon exercise of this Warrant.
The provisions of this Section 4.4(a) will similarly apply to successive Business Combinations. The Company will not effect any Business Combination described in this Section 4.4(a) unless, prior
to the consummation thereof, the successor Person (if other than the Company) resulting from such Business Combination, will assume, by written instrument substantially similar in form and substance to this Warrant and satisfactory to the Holder,
the obligation to deliver to the Holder such shares of stock, securities or assets that, in accordance with this Section 4, the Holder will be entitled to receive upon exercise of this Warrant. 

(b)    Notwithstanding anything to the contrary contained herein, with respect to any Business Combination,
the Holder will have the right to elect prior to the consummation of such Business Combination, to give effect to the exercise rights contained in Section 2 instead of giving effect to the provisions contained in this
Section 4.4 with respect to this Warrant. 
 4.5    Exercise Upon Change of
Control. Notwithstanding anything to the contrary contained herein, if the Holder elects to exercise this Warrant within sixty (60) days of a Material Event Redemption upon a Change of Control (each as defined in the Series A Certificate of
Designations) pursuant to Section 7 of the Series A Certificate of Designations, then (x) such Warrant shall be deemed to have been exercised prior to the consummation of such Change of Control and (y) the resulting Warrant Shares
shall be subject to Section 3.4 of the Stockholders Agreement at the time of such deemed exercise. 

4.6    Other Dividends and Distributions. If the Company, at any time after the issuance of this
Warrant, makes or declares, or fixes a record date (or a record date otherwise occurs) for the determination of holders of Common Stock entitled to receive, a dividend or any other distribution payable in securities of the Company (other than a
dividend or distribution of shares of Common Stock, Options or Convertible Securities on the outstanding shares of Common Stock), cash or other property, then, and in each such event, at the option of the Company, exercised by delivery of notice to
the Holder, provision will be made so that the Holder will receive upon exercise of the Warrant, in addition to the number of Warrant Shares receivable thereupon, the kind and amount of securities of the Company, cash or other property which the
Holder would have been entitled to receive had the Warrant been exercised in full into Warrant Shares on the date of such event (and the record date therefor) and had the Holder thereafter, during the period from the date of such event to and
including the Exercise Date, retained such securities, cash or other property receivable by them during such period, giving application to all adjustments called for during such period under Section 4.2(d) with respect to
the rights of the Holder; provided, that no such provision shall be made if the Holder receives, simultaneously with the distribution to the holders of Common Stock, a dividend or other distribution of such securities, cash or other property
in an amount equal to the amount of such securities, cash or other property as the Holder would have received if the Warrant had been exercised in full into Warrant Shares on the date of such event. 

  
 -8- 

 4.7    Certain Events. If any event of the type
contemplated by this Section 4 but not expressly provided for by this Section 4 (including the granting of stock appreciation rights, phantom stock rights or other rights with equity features)
occurs, then the Board and the Holder will jointly determine in good faith an appropriate adjustment in the number of Warrant Shares issuable upon exercise of this Warrant so as to protect the rights of the Holder in a manner consistent with this
Section 4. 
 4.8    Treasury Shares. The number of shares of Common
Stock outstanding at any given time will not include shares owned or held by or for the account of the Company or any of its wholly owned subsidiaries (“Treasury Shares”). The disposition of any Treasury Shares (other than the
cancellation or retirement thereof or the transfer of such shares among the Company and its wholly owned subsidiaries) will be considered an issue or sale of Common Stock for the purpose of this Section 4. 

4.9    Certificates. 

(a)    Capitalization Certificates. Upon reasonable request by the Holder, the Company will promptly
deliver to the Holder a certificate executed by a duly authorized officer thereof setting forth and certifying the total number of outstanding shares of Common Stock, Convertible Securities and Options and a calculation of the number of shares of
Common Stock available for issuance upon exercise of such Options, Convertible Securities and this Warrant. 

(b)    Adjustment Certificates. Without limiting Section 5.7(a), as
promptly as practicable following any adjustment of the number of Warrant Shares (but in any event not later than five (5) Business Days thereafter), the Company will furnish to the Holder a certificate executed by a duly authorized officer
(i) certifying the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of the Warrant thereof and (ii) setting forth in reasonable detail such adjustment and the facts
upon which it is based and certifying the calculation thereof. 
 4.10    Notices. In the event
(a) that the Company sets a record date (or a record date will otherwise occur) for any (i) dividend or other distribution on Common Stock, (ii) vote at a meeting (or action by written consent), (iii) right of holders of Common Stock
to subscribe for or purchase any shares of capital stock of any class or any other securities or (iv) right of holders of Common Stock to receive any other security or right in or to a security, (b) of a Business Combination or (c) of
the voluntary or involuntary dissolution, liquidation or winding up of the Company, the Company will send or cause to be sent to the Holder at least ten (10) days prior to the earlier of the applicable record date or the applicable expected
effective date, as the case may be, for the event, a written notice in accordance with Section 16 specifying, as the case may be, (A) the record date for such dividend, distribution, meeting or consent or other right
or action and a description of such dividend, distribution or other right or such action to be taken at such meeting or by written consent or (B) the effective date on which such Business Combination or dissolution, liquidation or winding up is
proposed to take place, and the date, if any is to be fixed, as of which the books of the Company will close or a record will be taken with respect to which the holders of record of Common Stock (or such other capital stock or securities at the time
issuable upon exercise of the Warrant) will be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property deliverable upon such Business Combination or dissolution, liquidation or
winding up, and the amount per share and character of such exchange applicable to the Warrant and the Warrant Shares. 

  
 -9- 

 4.11    Successive Adjustments. Any adjustments
made pursuant to this Section 4 will be made successively whenever an event referred to in this Section 4 occurs. 

5.    Transfer. Subject to this Section 5 and the transfer conditions referred to in the
legend endorsed hereon, this Warrant and all rights hereunder (as expressly modified by the Warrant Transfer Agreement, if applicable) are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant
to the Company at its then principal executive offices with a properly completed and duly executed warrant transfer agreement in the form attached hereto as Exhibit B (the “Warrant Transfer Agreement”). The Holder may not,
directly or indirectly, Transfer this Warrant if, as a result of such Transfer, the Company would become obligated to register the Common Stock or any other class of capital stock of the Company pursuant to Section 12(g) of the Exchange Act.
Upon such compliance, surrender and delivery, the Company will (a) execute and deliver a new Warrant or Warrants in the name of the transferee or transferees and in the denominations specified in such instrument of transfer, (b) issue to
the transferor a new Warrant evidencing the portion of this Warrant, if any, not so transferred and (c) promptly cancel this Warrant. The Company shall not be obligated to pay any documentary, stamp or similar issue or transfer taxes in respect
of the preparation, execution and delivery of such new Warrants pursuant to this Section 5. In connection with the transfer of this Warrant, the holder thereof shall deliver written notice to the Company describing in
reasonable detail such transfer or proposed transfer, which shall be accompanied by a representation from the transferee as to factual matters confirming that such transfer may be effected without registration of such Warrant under the Securities
Act of 1933. 
 6.    Holder Not Deemed a Stockholder; Limitations on Liability; Stockholders Agreement. 

(a)    Except as otherwise specifically provided herein, prior to the issuance to the Holder of the Warrant
Shares to which the Holder is then entitled to receive upon the exercise of this Warrant in accordance with the terms hereof, the Holder (in its capacity as such) will not be entitled to vote or receive dividends or be deemed the holder of shares of
capital stock of the Company for any purpose, and nothing in this Warrant will be construed to confer upon the Holder (in its capacity as such) any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any Business Combination or issuance or reclassification of stock), receive notice of meetings, receive dividends or subscription rights, or otherwise. Notwithstanding the foregoing, the Parties agree to treat ownership of
the Warrant as ownership of the underlying Common Stock for U.S. federal and, to the extent permitted by Law, state and local income tax purposes. 

(b)    Nothing in this Warrant will be construed as imposing any liabilities on the Holder to purchase any
securities (other than upon exercise of this Warrant) or as a stockholder of the Company, whether such liabilities are asserted by the Company, creditors of the Company or any other third Persons. 

(c)    In connection with the exercise of this Warrant and as a condition to the issuance of Warrant Shares
upon such exercise, the Holder shall (if not already a party thereto) execute and deliver to the Company a joinder to the Stockholders Agreement, substantially in the form attached hereto as Exhibit C. Additionally, the Holder shall (if not
already a party thereto) execute and deliver to the Company a joinder to the Registration Rights Agreement. The Company and the Holder acknowledge that upon delivery of the executed counterparts to the Stockholders Agreement and the Registration
Rights Agreement, Holder shall be entitled, as a Party and a beneficiary, to the rights thereunder solely with regard to their Warrant Shares. 

  
 -10- 

 7.    Effect of Violation. Any action or attempted action by the
Company in violation of this Warrant shall be null and void ab initio and of no force or effect whatsoever. 

8.    Replacement of Warrant. Upon 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) upon delivery of a customary indemnity agreement or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in
lieu thereof, a new Warrant of the same tenor and date. 
 9.    Registration Rights; Warrant Register. 

(a)    All Warrant Shares issuable upon exercise of this Warrant will be Registrable Securities (as defined

herein, nothing in this Agreement shall require, or be construed to require, the Holder, the Company or their respective Affiliates to (i) sell, hold, divest, discontinue or limit, or agree
to sell, hold, divest, discontinue or limit, any of their respective assets, businesses or interests or (ii) agree to any conditions relating to, or changes or restrictions in, the operations of any such assets, businesses or interests. 

11.    Entire Agreement; Parties in Interest. This Warrant, the Registration Rights Agreement and the Series A
Purchase Agreement constitute the entire agreement of, and supersede all other prior agreements and understandings (both written and oral) between, the parties hereto with respect to the subject matter hereof. In the event of any inconsistency
between this Warrant and the Series A Purchase Agreement with respect to the subject matter hereof, this Warrant will control. This Warrant will be binding upon and inure solely to the benefit of the Company and the Holder and their respective
successors and permitted assigns, and nothing in this Warrant, express or implied, is intended to or will confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Warrant. 

12.    Governing Law. This Warrant and all questions relating to the interpretation or enforcement of this Warrant
will be governed by and construed in accordance with the Laws of the State of Delaware without regard to the Laws of the State of Delaware or any other jurisdiction that would call for the application of the substantive Laws of any jurisdiction
other than Delaware. 
 13.    Jurisdiction. Each party hereto irrevocably and unconditionally, for itself and
its property, submits to exclusive jurisdiction in the Delaware Court of Chancery (and if jurisdiction in the Delaware Court of Chancery is unavailable, in the Complex Commercial Litigation Division of Superior Court in the City of Wilmington, New
Castle County, Delaware, and if jurisdiction in the Complex Commercial Litigation Division of the Superior Court in the City of Wilmington, New Castle County, Delaware is unavailable, in the Federal courts of the U.S. sitting in the State of
Delaware), and any appellate court from any thereof (such courts in such jurisdictional priority, the “Forum”), in any dispute, action or other proceeding arising out of or relating to this Warrant or any transaction contemplated
hereby, and agrees that all claims in respect of such dispute or proceeding may be heard and determined in the Forum, and each of the parties hereby irrevocably and unconditionally (a) agrees not to commence any such dispute or proceeding
except in the Forum, (b) agrees that any claim in respect of any such dispute or proceeding may be heard and determined in the Forum, (c) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or
hereafter have to the laying of venue of any such dispute or proceeding in the Forum, and (d) waives, to the fullest extent it may legally and effectively do so, the defense of an inconvenient forum to the maintenance of such dispute or
proceeding in the Forum. Each party hereby agrees that service of summons, complaint or other process in connection with any dispute, action or other proceedings contemplated hereby may be made by registered or certified mail addressed to such party
at the address specified pursuant to Section 16, and that service so made will be effective as if personally made in the State of Delaware. 

14.    Waiver of Jury Trial. EACH OF THE COMPANY AND THE HOLDER IRREVOCABLY WAIVES ANY RIGHT TO TRIAL BY JURY IN
ANY DISPUTE, ACTION OR OTHER PROCEEDING BETWEEN OR AMONG SUCH PERSONS ARISING OUT OF OR RELATING TO THIS WARRANT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

15.    Remedies. 

(a)    Certain Disputes. If, with respect to a determination of (i) the net amount of cash or
fair value, as applicable, under Section 4.2(e), (ii) an appropriate adjustment to the number of Warrant Shares issuable hereunder under Section 4.6 or (iii) the Fair Market Value, if being
determined pursuant to clause (e) of such definition, under Section 2.1(b) or Section 4, the Board 

  
 -12- 

 
and the Holder are unable to come to an agreement in good faith within ten (10) days after the date on which the event giving rise to the parties’ obligations to jointly make such
determination in good faith occurred, such determination will be made by a nationally recognized investment banking, accounting or valuation firm jointly selected by the Board and the Holder (the “Valuation Firm”). If such
determination is being made under Section 2.1(b), Section 4.2(e) or Section 4, in making such determination, the Valuation Firm will assume an orderly sale transaction
between a willing buyer and a willing seller and use valuation techniques then prevailing in the securities industry. If such determination is being made under Section 2.1(b), it will be made without regard to the lack of
liquidity of the Common Stock due to any restrictions (contractual or otherwise) applicable thereto or any discount for minority interests and will assume full disclosure of all relevant information and a reasonable period of time for effectuating
such sale. The determination of the Valuation Firm will be final and conclusive, and the fees and expenses of the Valuation Firm will be borne by the Company, on the one hand, and by the Holder, on the other hand, based upon the percentage that the
amount actually contested but not awarded to the Company or the Holder, respectively, bears to the aggregate amount actually contested by the Company and the Holder. 

(b)    Remedies Cumulative. Except as set forth in Section 15(a),
all remedies available under this Warrant, at law, in equity or otherwise will be deemed cumulative and not alternative or exclusive of other remedies, and the exercise by any party hereto of a particular remedy will not preclude the exercise of any
other remedy. 
 (c)    Injunctive Relief. Each party hereto acknowledges and agrees that the
other party hereto would be irreparably damaged if any of the provisions of this Warrant are not performed in accordance with their specific terms and that any breach of this Warrant by such other party could not be adequately compensated in all
cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which the parties hereto may be entitled, at law or in equity, each party hereto will be entitled to enforce any provision of this Warrant by a decree of
specific performance and temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Warrant, without posting any bond or other undertaking. 

16.    Notice.

Warrant will be in writing and delivered by (i) email or (ii) overnight delivery via a national courier service to the following email address or physical address, as applicable:

the Series A Purchase Agreement and exercisable for shares of Common Stock (this Warrant, together with such other warrants and any replacement warrants or other warrants issued hereunder or thereunder, the “Series A
Warrants”). Any term or condition of this Warrant may be amended or waived, by written consent of (a) the Holder and the Company (in the case of an amendment), or by the party against whom the waiver is effective, or (b) the

Common Stock issuable upon exercise of this Warrant, and the exercise price therefor, may not be amended without the approval of the Holder. No knowledge, investigation or inquiry, or failure or delay by the Company or the Holder in exercising any
right hereunder will operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. 

18.    Counterparts. This Warrant may be executed in two or more counterparts, each of which constitutes an
original, and all of which taken together constitute one instrument. 
 19.    Assignment by the Company and
Holder. The Company may not, without the prior written consent of the Holder, sell, transfer (by operation of law or otherwise) or assign this Warrant or any of its rights or obligations hereunder. The Holder may transfer this Warrant so long as
such transfer is in compliance with Section 5. 
 20.    Severability. If any provision
of this Warrant, or the application thereof becomes or is declared by a court of competent jurisdiction to be illegal, void, invalid or unenforceable, the remainder of this Warrant will continue in full force and effect and the application of such
provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to replace such illegal, void, invalid or unenforceable provision of this Warrant with a
legal, valid and enforceable provision that achieves, to the extent possible, the economic, business and other purposes of such illegal, void, invalid or unenforceable provision.
