1.Grant of Shares of Restricted Stock. The Company hereby grants to the individual (“Participant”) named in the Notice of Grant of Restricted Stock of this Award Agreement (the “Notice of Grant”) under the Plan an Award of Shares of Restricted Stock, subject to the terms and conditions of this Award Agreement and the Plan, which is incorporated herein by reference. Subject to Section 19(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Award Agreement, the terms and conditions of the Plan shall prevail.

2.Vesting Schedule. Except as provided in Section 3 and subject to Sections 4 and 7, the Shares of Restricted Stock awarded by this Award Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Shares of Restricted Stock scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in accordance with any of the provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs.

3.Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Shares of Restricted Stock subject to this Award Agreement at any time, subject to the terms of the Plan. If so accelerated, such Shares of Restricted Stock will be considered as having vested as of the date specified by the Administrator.

4.Forfeiture Upon Termination as a Service Provider. Unless specifically provided otherwise in this Award Agreement or other written agreement between Participant and the Company or any of its Subsidiaries or Parents, as applicable, the balance of the Shares of Restricted Stock that have not vested as of the time Participant ceases to be a Service Provider for any or no reason will be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company upon the date of such termination and Participant will have no further rights thereunder. Participant will not be entitled to a refund of the price paid for the Shares of Restricted Stock, if any, returned to the Company pursuant to this Section 4. Participant hereby appoints the Escrow Agent with full power of substitution, as Participant’s true and lawful attorney-in-fact with irrevocable power and authority in the name and on behalf of Participant to take any action and execute all documents and instruments, including, without limitation, stock powers which may be necessary to transfer the certificate or certificates evidencing such unvested Shares to the Company upon such termination of service.

5.Tax Consequences. Participant has reviewed with his or her own tax advisors the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Award Agreement. With respect to such matters, Participant relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be solely responsible for Participant’s own Tax-Related Items (as defined

in Section 7 below) that may arise as a result of this investment or the transactions contemplated by this Award Agreement.

6.Death of Participant. Any distribution or delivery to be made to Participant under this Award Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, provided such designation is valid under Applicable Laws, or if no beneficiary survives Participant, the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

7.Tax-Related Items

a.Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”) or any Parent or Subsidiary to which Participant is providing services (together, the “Service Recipients”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Shares of Restricted Stock, including, without limitation, (i) all federal, state, and local taxes (including Participant’s Federal Insurance Contributions Act (FICA) obligations) that are required to be withheld by any Service Recipient or other payment of tax-related items related to Participant’s participation in the Plan and legally applicable to Participant, (ii) Participant’s and, to the extent required by any Service Recipient, the Service Recipient’s fringe benefit tax liability, if any, associated with the grant, vesting, or release from escrow of the Shares of Restricted Stock, the filing of an election under Section 83(b) of the Code (the “83(b) Election”) with respect to the Shares of Restricted Stock, or the sale of Shares, and (iii) any other Service Recipient taxes the responsibility for which Participant has, or has agreed to bear, with respect to the Shares of Restricted Stock (or exercise thereof or issuance of Shares thereunder) (collectively, the “Tax-Related Items”), is and remains Participant’s sole responsibility and may exceed the amount actually withheld by the applicable Service Recipient(s). Participant further acknowledges that no Service Recipient (A) makes any representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Shares of Restricted Stock, including, but not limited to, the grant, vesting or release from escrow of the Shares of Restricted Stock, the filing of an 83(b) Election with respect to the Shares of Restricted Stock, the subsequent sale of Shares acquired pursuant to this Award Agreement and the receipt of any dividends or other distributions (subject to Section 12(f)), and (B) makes any commitment to and is under any obligation to structure the terms of the grant or any aspect of the Shares of Restricted Stock to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Participant understands that Section 83 of the Code taxes as ordinary income the difference between the purchase price, if any, for the Shares and the Fair Market Value of the Shares as of each vesting date. If Participant is a U.S. taxpayer, Participant understands that Participant may elect, for purposes of U.S. tax law, to be taxed at the time the Shares are granted rather than when such

Shares vest by filing an 83(b) Election with the IRS within thirty (30) days from the date of grant of the Restricted Stock Award.

b.Tax Withholding. Notwithstanding any contrary provision of this Award Agreement, no certificate representing the Shares of Restricted Stock may be released from the escrow established pursuant to Section 12, unless and until satisfactory arrangements (as determined by the Administrator) will have been made by Participant with respect to the payment of all Tax-Related Items. When Shares of Restricted Stock are vested, Participant generally will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit Participant to satisfy such Tax-Related Items, in whole or in part (without limitation), if permissible by applicable local law, by (i) requiring Participant to make a payment in a form acceptable to the Company, (ii) withholding in Shares to be released from the escrow established pursuant to Section 12, (iii) withholding from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Service Recipient, (iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax Tax-Related Items, or (v) withholding from proceeds of the sale of Shares released from the escrow established pursuant to Section 12 either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent). To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to Participant and, until determined otherwise by the Company, this will be the method by which such Tax-Related Items are satisfied. The Company may withhold or account for Tax-Related Items by considering statutory or other withholding rates, including minimum or maximum rates applicable in Participant’s jurisdiction(s). Further, if Participant is subject to tax in more than one jurisdiction between the Date of Grant and a date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges and agrees that the Company and/or the Service Recipient (and/or former employer, as applicable) may be required to withhold or account for tax in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of such Tax-Related Items hereunder at the time of the applicable tax event for any Shares, Participant will permanently forfeit such Shares, and such Shares will be returned to the Company at no cost to the Company.

c.No Representations. Participant has reviewed with his or her own tax advisers the U.S. federal, state, local and non-U.S. tax consequences investment and the transactions contemplated by this Award Agreement. With respect to such matters, Participant relies solely on such advisers and not on any statements or representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for

Participant’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Award Agreement.

d.Company’s Obligation to Release Shares. For clarification purposes, in no event will the Company release Shares from the escrow established pursuant to Section 12 unless and until arrangements satisfactory to the Administrator have been made for the payment of Participant’s Tax Withholding Obligation. If Participant fails to make satisfactory arrangements for the payment of such Tax Withholding Obligations hereunder at the time any applicable Shares of Restricted Stock otherwise are scheduled to vest pursuant to Sections 2 or 3, at the time Participant’s Tax Withholding Obligations otherwise become due, Participant will permanently forfeit such Shares of Restricted Stock to which Participant’s Tax Withholding Obligation relates and any right to receive Shares thereunder and such Shares of Restricted Stock will be returned to the Company at no cost to the Company.

8.Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account) or the Escrow Agent. Except as provided in Section 12(f), after such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.

9.No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE SHARES OF RESTRICTED STOCK PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER, WHICH UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW IS AT THE WILL OF THE APPLICABLE SERVICE RECIPIENT, AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS RESTRICTED STOCK AWARD OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF ANY SERVICE RECIPIENT TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW, MAY BE AT ANY TIME, WITH OR WITHOUT CAUSE.

10.Grant is Not Transferable. Except for the escrow described in Section 12 or transfer of the Shares to the Company or its assignees contemplated by this Award Agreement, and

except to the limited extent provided in Section 6, the unvested Shares subject to this Award Agreement and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process until such Shares shall have vested in accordance with the provisions of this Award Agreement. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of the unvested Shares subject to this Award Agreement, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, the then-unvested Shares of Restricted Stock will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

11.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan.

12.Escrow of Shares.

a.All Shares of Restricted Stock will, upon execution of this Award Agreement, be delivered and deposited with an escrow holder designated by the Company (the “Escrow Holder”). The Shares of Restricted Stock will be held by the Escrow Holder until such time as the Shares of Restricted Stock vest or the date Participant ceases to be a Service Provider.

b.The Escrow Holder will not be liable for any act it may do or omit to do with respect to holding the Shares of Restricted Stock in escrow and while acting in good faith and in the exercise of its judgment.

c.Upon Participant ceasing to be a Service Provider for any reason, the Escrow Holder, upon receipt of written notice of such termination, will take all steps necessary to accomplish the transfer of the unvested Shares of Restricted Stock to the Company. Participant hereby appoints the Escrow Holder with full power of substitution, as Participant’s true and lawful attorney‑in‑fact with irrevocable power and authority in the name and on behalf of Participant to take any action and execute all documents and instruments, including, without limitation, stock powers which may be necessary to transfer the certificate or certificates evidencing such unvested Shares of Restricted Stock to the Company upon such termination.

d.The Escrow Holder will take all steps necessary to accomplish the transfer of Shares of Restricted Stock to Participant after they vest following Participant’s request that the Escrow Holder do so.

e.Subject to the terms hereof, Participant shall have all the rights of a stockholder with respect to such Shares while they are held in escrow, including without

limitation, the right to vote the Shares and receive any cash dividends declared thereon (subject to subsection (f) below).

f.In the event of any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares, the Shares of Restricted Stock will be increased, reduced or otherwise changed, and by virtue of any such change Participant will in his or her capacity as owner of unvested Shares of Restricted Stock be entitled to new or additional or different shares of stock, cash or securities (other than rights or warrants to purchase securities); such new or additional or different shares, cash or securities will thereupon be considered to be unvested Shares of Restricted Stock and will be subject to all of the conditions and restrictions which were applicable to the unvested Shares of Restricted Stock pursuant to this Award Agreement. If Participant receives rights or warrants with respect to any unvested Shares of Restricted Stock, such rights or warrants may be held or exercised by Participant, provided that until such exercise any such rights or warrants and after such exercise any shares or other securities acquired by the exercise of such rights or warrants will be considered to be unvested Shares of Restricted Stock and will be subject to all of the conditions and restrictions which were applicable to the unvested Shares of Restricted Stock pursuant to this Award Agreement. The Administrator in its absolute discretion at any time may accelerate the vesting of all or any portion of such new or additional shares of stock, cash or securities, rights or warrants to purchase securities or shares or other securities acquired by the exercise of such rights or warrants.

g.The Company may instruct the transfer agent for its Common Stock to place a legend on the certificates representing the Restricted Stock or otherwise note its records as to the restrictions on transfer set forth in this Award Agreement.

13.Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be addressed to the Company at Dropbox, Inc., 1800 Owens Street, Suite 200, San Francisco, CA 94158, or at such other address as the Company may hereafter designate in writing.

14.Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to the Shares of Restricted Stock awarded under the Plan or future Shares of Restricted Stock that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through any online or electronic system established and maintained by the Company or a third party designated by the Company, now or in the future. Participant must provide the Company or any designated third party administrator with a paper copy of any documents if his or her attempted electronic delivery of such document fails.

15.No Waiver. Either party’s failure to enforce any provision or provisions of this Award Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Award Agreement. The rights granted both parties herein are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances.

16.Successors and Assigns. The Company may assign any of its rights under this Award Agreement to single or multiple assignees, and this Award Agreement shall inure to the benefit of the successors and assigns of the Company.

The rights and obligations of Participant under this Award Agreement may be assigned only with the prior written consent of the Company.

17.Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or non-U.S. law, the tax code and related regulations or under the rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange Commission or any other governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to Participant (or his or her estate) or the Escrow Holder hereunder, such issuance will not occur unless and until such listing, registration, qualification, rule compliance, clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Subject to the terms of the Award Agreement and the Plan, the Company shall not be required to issue any certificate or certificates for (or make any entry on the books of the Company or of a duly authorized transfer agent of the Company of) Shares hereunder prior to the lapse of such reasonable period of time following the Date of Grant of the Shares of Restricted Stock as the Administrator may establish from time to time for reasons of administrative convenience.

18.Interpretation. The Administrator will have the power to interpret the Plan and this Award Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares of Restricted Stock have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any person acting on behalf of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Award Agreement.

Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the Administrator at any time.

21.Modifications to the Award Agreement. This Award Agreement constitutes the entire understanding of the parties on the subjects covered. Participant expressly warrants that he or she is not accepting this Award in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Award Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Award Agreement, the Company reserves the right to revise this Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A in connection with this Award of Shares of Restricted Stock.

22.Governing Law; Venue; Severability. This Award Agreement and the Shares of Restricted Stock are governed by the internal substantive laws, but not the choice of law rules, of California. For purposes of litigating any dispute that arises under this Restricted Stock Award or this Award Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of San Francisco County, California, or the United States federal courts for the Northern District of California, and no other courts, where this Award Agreement is made and/or to be performed. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Award Agreement shall continue in full force and effect.

23.Entire Agreement. The Plan is incorporated herein by this reference. The Plan and this Award Agreement (including the appendices and exhibits referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

24.Country Addendum. The Restricted Stock grant shall be subject to any additional terms and conditions set forth in the Country Addendum for Participant’s country, attached hereto as Exhibit C. Moreover, if Participant relocates to one of the countries included in the Country Addendum, if any, the terms and conditions for such country will apply to Participant to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Country Addendum constitutes part of this Award Agreement.

1.Market-Based Condition. The Target Number of Shares of Restricted Stock (the “Target Shares”) shall be allocated into three separate tranches (each, a “Grant Tranche”) as follows:

a.1/3rd of the Target Number of Shares of Restricted Stock will be allocated to the First Measurement Period (the “First Grant Tranche”);

b.1/3rd of the Target Number of Shares of Restricted Stock will be allocated to the Second Measurement Period (the “Second Grant Tranche”); and

c.1/3rd of the Target Number of Shares of Restricted Stock will be allocated to the Third Measurement Period (the “Third Grant Tranche”).

If the Target Shares are not evenly divisible into the three Grant Tranches, then any fractional number of Target Shares that would otherwise be allocated to a Grant Tranche shall be allocated to the next Grant Tranche, until the fractional number of Target Shares sum to a whole Target Share.

The actual number of Shares subject to each Grant Tranche that will vest will be determined based upon the achievement of Company Stock Price Target(s) during the applicable Measurement Period and the satisfaction of the applicable service‑based vesting conditions, all in accordance with this Exhibit B.

2.Company Stock Price. Except as set forth in Sections 3 through 5 of this Exhibit B, on each trading day that a Company Stock Price Target in the table below (the “Table”) is achieved during a Measurement Period (each, an “Achievement Date”), a number of Shares subject to the Grant Tranche for that Measurement Period will become eligible to vest (such Shares, the “Eligible Shares”) equal to (a) the product of (x) the Target Shares allocated to that Grant Tranche multiplied by (y) the percentage indicated in the “Multiplier” column of the Table that corresponds to such Company Stock Price Target that was achieved (rounded to the nearest whole Share), minus (b) the number of Shares subject to the Grant Tranche that already became Eligible Shares upon the achievement of any lower Company Stock Price Target (if any). Such Eligible Shares will vest (a) in full on the applicable Vesting Date subject to Participant satisfying the Service Condition through such date, or (b) to the extent provided under Sections 4 or 5. Except in connection with a Change in Control as set forth in Section 5 of this Exhibit B, no partial achievement will occur and no Shares will become Eligible Shares for achievement between two Company Stock Price Targets. For the avoidance of doubt, (a) more than one Company Stock Price Target may be achieved on a particular Achievement Date (which will result in the cumulative number of Eligible Shares for the applicable Grant Tranche being equal to the product obtained by multiplying (x) the Target Shares allocated to that Grant Tranche multiplied by (y) the percentage indicated in the “Multiplier” column of the Table that corresponds to the highest Company Stock Price Target that was achieved on such date), and (b) each Company Stock Price Target may only be achieved once during a Measurement Period (such that once any Share subject to

the Award has become an Eligible Share, no decrease in the Company Stock Price will cause such Share to cease to be an Eligible Share).

* In order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under this Award Agreement, the Administrator shall make appropriate adjustments to the Company Stock Price Targets to reflect any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split‑up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares.

For example, assume (i) the Company Stock Price as of February 15, 2021 is $10.10 and (ii) the Company Stock Price as of April 15, 2021 is $17.50. February 15, 2021 would be the first Achievement Date, which would result in 25% of the First Grant Tranche Target Shares becoming Eligible Shares. April 15, 2021 would be an Achievement Date that results in an additional 25% of the First Grant Tranche Target Shares becoming Eligible Shares (equal to (x) the 50% of the First Grant Tranche Target Shares that corresponds to the $15.00 Company Stock Price Target minus (y) the 25% of the First Grant Tranche Target Shares that had previously become Eligible Shares). Such Eligible Shares would vest (a) in full on the Vesting Date of the First Grant Tranche (February 15, 2022) subject to Participant satisfying the Service Condition through such date, or (b) to the extent provided under Sections 4 or 5.

3.Service Condition and Forfeiture. Except as otherwise provided in Sections 4 or 5, (a) in order for any Shares hereunder to become Eligible Shares, Participant must have continuously satisfied the Service Condition through the applicable Achievement Date, and (b) in order for any Eligible Shares to vest, Participant must satisfy the Service Condition through the applicable Vesting Date. Upon the end of each Measurement Period, any Shares subject to this Award that may no longer become Eligible Shares due to the failure to achieve the applicable Company Stock Price Target will be immediately forfeited and returned to the Company, and Participant will have no further rights with respect to such Shares.

4.Qualified Termination.

a.Non-CIC Qualified Termination. If Participant experiences a Non-CIC Qualified Termination (as defined in the Severance Agreement) after the commencement of a Measurement Period but prior to the Vesting Date of the Grant Tranche relating to such Measurement Period, then 25% of the number of Shares allocated to such Grant Tranche that became Eligible Shares prior to the date of the Non-CIC Qualified Termination or any portion of the Grant Tranche would have become Eligible Shares had Participant remained employed by the Company through the end of the Measurement Period (or if a Change in Control occurs prior to the end of the Measurement Period, through the date of the Change in Control) based on the actual achievement of the Company Stock Price Targets for such Measurement Period will vest on the Vesting Date immediately following the completion of such Measurement Period (or, if earlier, immediately prior to a Change in Control), subject to Participant satisfying the conditions set forth in Section 5 of the Severance Agreement. For the avoidance of doubt, notwithstanding anything in the Severance Agreement to the contrary, the equity vesting benefits under Sections 3(a)(iii) of the Severance Agreement will not apply to any of the Shares subject to the Award.

b.CIC Qualified Termination. If Participant experiences a CIC Qualified Termination (as defined in the Severance Agreement) prior to the Vesting Date of a Grant Tranche, then the number of Shares allocated to such Grant Tranche that are Eligible Shares and that will vest as of immediately prior to the Change in Control will be determined pursuant to Section 5 of this Exhibit B as if Participant had remained employed by the Company through the date of the Change in

Control, subject to Participant satisfying the conditions set forth in Section 5 of the Severance Agreement. For the avoidance of doubt, notwithstanding anything in the Severance Agreement to the contrary, the equity vesting benefits under Sections 3(b)(iv) of the Severance Agreement will not apply to any of the Shares subject to the Award.

5.Change in Control. If a Change in Control occurs prior to the Vesting Date of a Grant Tranche and Participant satisfies the Service Condition through the date of the Change in Control, then the following rules will apply.

a.If the Measurement Period for such Grant Tranche has not yet ended:

i.Immediately prior to the Change in Control, rather than applying the definition of “Company Stock Price” below, “Company Stock Price” instead will mean the Per Share Deal Price. “Per Share Deal Price” means the value of the total amount of consideration received or potentially receivable for a Share by holders of the Company’s Class A Common Stock in connection with the Change in Control. The value of any non-cash consideration will be determined in good faith by the Administrator.

ii.After determining the Company Stock Price under Section 5(a)(i) of this Exhibit B, the same rules under the Table apply in determining whether any additional Company Stock Price Targets are achieved and additional Shares subject to this Award will become Eligible Shares; provided, however, that if Company Stock Price as determined under Section 5(a)(i) of this Exhibit B is greater than $25.00 but falls between two Company Stock Price Targets set forth in the Table, an additional number of Shares subject to the Grant Tranche will become Eligible Shares equal to (a) the product obtained by multiplying (x) the Target Shares allocated to the Grant Tranche multiplied by (y) the percentage determined based on a linear interpolation between (A) the percentage indicated in the “Multiplier” column of the Table that corresponds to the Company Stock Price Target in the Table that is greater than but closest to the Company Stock Price determined under Section 5(a)(i) of this Exhibit B and (B) the percentage indicated in the “Multiplier” column of the Table that corresponds to the Company Stock Price Target in the Table that is less than but closest to the actual Company Stock Price determined under Section 5(a)(i) of this Exhibit B (rounded to the nearest whole Share), minus (b) the number of Shares subject to the Grant Tranche that already became Eligible Shares upon the achievement of any lower Company Stock Price Target (if any).

b.After applying the rules in Section 5(a) of this Exhibit B (if applicable), all Eligible Shares (including any Shares that become Eligible Shares under Section 5(a) of this Exhibit B) will vest as of immediately prior to the Change in Control.

For example, assume (i) the Company Stock Price as of February 15, 2021 is $10.10 and (ii) there is a Change in Control on July 1, 2021 for a Per Share Deal Price of $27.50.
