awards to Participant (as of the date indicated below) a Restricted Stock Unit Award for the number of shares of the Company’s common stock (the “Common Stock”) set forth below (the “Award”). The
Award is subject to all of the terms and conditions as set forth herein and in the Plan and the Restricted Stock Unit Award Agreement, both of which are attached hereto and incorporated herein in their entirety. Capitalized terms not otherwise
defined herein will have the meanings set forth in the Plan or the Restricted Stock Unit Award Agreement. In the event of any conflict between the terms in the Award and the Plan, the terms of the Plan will control. If the Company uses an electronic

 Expiration Date: The Expiration Date for an RSU is the earlier of: (i) the Liquidity Event Deadline or
(ii) the date the Participant’s Continuous Service terminates. 
 Vesting: Participant will receive a benefit with respect to an RSU only
if it vests (and thereby becomes a “Vested RSU”). Except as explicitly set forth below, two vesting requirements must be satisfied on or before the applicable Expiration Date specified above in order for an RSU to vest —
a time and service-based requirement (the “Service-Based Requirement”) and the “Liquidity Event Requirement” (each as described below). An RSU shall become a Vested RSU on the first date upon which
both the Service-Based Requirement and the Liquidity Event Requirement are satisfied with respect to that particular RSU (the “Vesting Date”). All RSUs that do not become Vested RSUs on or before the applicable
Expiration Date will be immediately forfeited to the Company upon expiration at no cost to the Company. For purposes hereof, the term “Quarterly Date” shall mean each of February 15, May 15, August 15 and
November 15. 
 Service-Based 
 Requirement: (1)
The Service-Based Requirement will be satisfied in installments as to the RSUs as follows: (i) 25% of the total number of RSUs granted on the first Quarterly Date following the first anniversary of the Vesting Commencement Date, and (ii) the
remaining RSUs, in 12 equal quarterly installments (rounded down to the nearest whole share except for the last installment) on each Quarterly Date thereafter, provided that Participant remains in Continuous Service through each such date. For the
avoidance of doubt, if Participant’s Continuous Service terminates prior to the Liquidity Event Requirement being met, all RSUs subject to the Award will be forfeit at no cost to the Company and Participant will have no further right, title or
interest in or to such underlying shares of Common Stock.

 (2) The Service-Based Requirement will be satisfied in installments as to the RSUs in 12 equal quarterly
installments (rounded down to the nearest whole share except for the last installment) on each Quarterly Date following the date hereof, provided that Participant remains in Continuous Service through each such date. For the avoidance of doubt, if
Participant’s Continuous Service terminates prior to the Liquidity Event Requirement being met, all RSUs subject to the Award will be forfeit at no cost to the Company and Participant will have no further right, title or interest in or to such
underlying shares of Common Stock. 
 Liquidity Event 

Requirement: The Liquidity Event Requirement will be satisfied as to any then-outstanding RSUs on the first to occur of: (1) a Change in Control in
which holders of shares of Common Stock receive cash and/or marketable securities traded on an established national or foreign securities exchange, (2) the expiration of the Lock-up (as such term is
defined in the Form of Lock-Up Agreement attached as Annex G to the Business Combination Agreement, dated as of October 13, 2021, by and among RedBall Acquisition Corp., the Company, Showstop Merger Sub I
Inc. and Showstop Merger Sub II LLC), or (3) the date that is six months and one day following (x) the effective date of a registration statement of the Company filed under the Securities Act for the sale of the Company’s Common
Stock; (y) the Company’s completion of a merger or consolidation with a special purpose acquisition company or its subsidiary in which the common stock (or similar securities) of the surviving or parent entity are publicly traded in a
public offering pursuant to an effective registration statement under the Securities Act (a “SPAC Transaction”), or (z) the settlement of the initial trade of shares of the Company’s Common Stock on the Nasdaq
Global Select Market, the New York Stock Exchange or another exchange or marketplace approved by Board by means of an effective registration statement under the Securities Act that registers shares of existing Common Stock of the Company for resale
(a “Direct Listing”). 
 Settlement: If an RSU vests as provided for above, subject to adjustment in accordance with
Section 3 of the Restricted Stock Unit Award Agreement, the Company will deliver one share of Common Stock (or its cash equivalent, at the discretion of the Company) for each Vested RSU. The shares will be issued in accordance with the issuance
schedule set forth in Section 5 of the Restricted Stock Unit Award Agreement. 
 Additional Terms/Acknowledgements: Participant acknowledges
receipt of, and understands and agrees to, this Restricted Stock Unit Grant Notice, the Restricted Stock Unit Award Agreement and the Plan (the “Grant Documents”). Participant further acknowledges that as of the Date of
Grant, the Grant Documents set forth the entire understanding between Participant and the Company regarding this Award and supersede all prior oral and written agreements, offer letters, promises and/or representations on that subject with the
exception of (i) equity awards previously granted and delivered to Participant, and (ii) any compensation recovery policy that is adopted by the Company or is otherwise required by applicable law. Furthermore, by accepting the Award,
Participant consents to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 
 Notwithstanding the above, if Participant has not actively accepted the Award within 90 days of the Date of Grant set forth in
this Restricted Stock Unit Grant Notice, Participant is deemed to have accepted the Award, subject to all of the terms and conditions of the Grant Documents.

 ATTACHMENT I 

SEATGEEK INC. 
 A DELAWARE
CORPORATION 
 2017 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AWARD AGREEMENT 

Pursuant to the Restricted Stock Unit Grant Notice (the “Grant Notice”) and this Restricted Stock Unit Award Agreement (the
“Agreement”) and in consideration of your services, SeatGeek, Inc. (the “Company”) has awarded you a Restricted Stock Unit Award (the “Award”) under its 2017 Equity Incentive
Plan, as amended (the “Plan”). The Award is granted to you effective as of the Date of Grant set forth in the Grant Notice for this Award. Capitalized terms not explicitly defined in this Agreement will have the same meanings
given to them in the Plan and Grant Notice. In the event of any conflict between the terms in this Agreement and the Plan, the terms of the Plan will control. The details of the Award, in addition to those set forth in the Grant Notice and the Plan,
are as follows. 
 1. GRANT OF THE AWARD. This Award
represents the right to be issued on a future date one (1) share of Common Stock for each Restricted Stock Unit (“RSU”) that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 below) as
indicated in the Grant Notice. Notwithstanding the foregoing, the Company reserves the right to issue you the cash equivalent of Common Stock, in part or in full satisfaction of the delivery of Common Stock in connection with the vesting of the
RSUs, and, to the extent applicable, references in this Agreement and the Grant Notice to Common Stock issuable in connection with your RSUs will include the potential issuance of its cash equivalent pursuant to such right. This Award was granted in
consideration of your services to the Company. 
 2. VESTING. Subject to the limitations contained
herein, the Award will vest in accordance with the vesting schedule provided in the Grant Notice. Upon the termination of your Continuous Service prior to the Liquidity Event Requirement being met, all units or shares (including those that have
satisfied any time and service-based requirement) will be forfeited at no cost to the Company and you will have no further right, title or interest in or to such underlying shares of Common Stock. 

3. NUMBER OF SHARES. The number of RSUs subject to your Award may be adjusted
from time to time for any adjustment events as provided in Section 9(a) of the Plan. Any additional RSUs, shares, cash or other property that becomes subject to the Award pursuant to this Section 3, if any, shall be subject, in a manner determined
by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other RSUs and shares covered by your Award. Notwithstanding the provisions of this Section 3, no fractional
shares or rights for fractional shares of Common Stock shall be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share. 

4. SECURITIES LAW AND OTHER COMPLIANCE. You may
not be issued any Common Stock under your Award unless the shares of Common Stock underlying the RSUs are either (i) then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the
registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt would not be in
material compliance with such laws and regulations 

  
 1 












 5. DATE OF ISSUANCE. 

(a) Subject to the satisfaction of the Tax-Related Items set forth in Section 13 of this Agreement, in the event one or more RSUs vest,
the Company will issue to you one (1) share of Common Stock for each RSU that vests on the applicable Vesting Date (subject to any adjustment under Section 3 above) (such date, the “Original Issuance Date”). 

(b) If the Original Issuance Date falls on a date that is not a business day, issuance will instead occur on the next following business day. In
addition, to the extent applicable at a Vesting Date when the Common Stock is registered under the Securities Act, if: 
 (i) the Original Issuance
Date does not occur (1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise
permitted to sell shares of Common Stock on an established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was
entered into in compliance with the Company’s policies (a “10b5-1 Arrangement”)), and 
 (ii) either (1) no
Tax-Related Items apply, or (2) the Company decides, prior to the Original Issuance Date, (A) not to satisfy the Tax-Related Items by withholding shares of Common Stock from the shares of Common Stock otherwise due, on the Original Issuance Date, to
you under this Award, and (B) not to permit you to enter into a “same day sale” commitment with a broker-dealer pursuant to Section 13 of this Agreement (including but not limited to a commitment under a 10b5-1 Arrangement) and (C) not to
permit you to pay the Tax-Related Items in cash, then the shares of Common Stock that would otherwise be issued to you on the Original Issuance Date will not be issued on such Original Issuance Date and will instead be issued as soon as
practicable after the date that you are no longer prohibited from selling shares of Common Stock in the open public market, but in no event later than (a) December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last
day of your taxable year in which the Original Issuance Date occurs), or (b) if and only if permitted in a manner that complies with Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month
of the year immediately following the year in which the shares of Common Stock covered by this Award are no longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d). 

(c) The form of such issuance (e.g., a stock certificate or electronic entry evidencing such shares of Common Stock) will be
determined by the Company. In all cases, the issuance of shares under this Award is intended to comply with Treasury Regulations Section 1.409A-1(b)(4) and will be construed and administered in such a manner. 

6. DIVIDENDS. You will receive no benefit or adjustment to your RSUs with respect to
any cash dividend, stock dividend or other distribution except as provided in the Plan with respect to an adjustment event described under Section 9(a) of the Plan. 

7. Lock-up Period. By accepting the Award, you agree that you will not sell, dispose of, transfer, make any short sale of, grant any option for the
purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by you, during the Lock-up; provided, however, that nothing contained in
this Section 7 will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-up. You further agree to execute and deliver such other agreements as may be reasonably requested by the Company and the underwriters
that are consistent with the foregoing or that are necessary to give further effect thereto. You 

  
 2 












 
also agree that any transferee of any shares of Common Stock (or other securities of the Company held by you) will be bound by this Section 7. To enforce the foregoing covenant, the Company
may impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 7 and will have the right, power
and authority to enforce the provisions of this Section 7 as though they were a party to this Agreement. You further agree that the obligations contained in this Section 7 shall also, if so determined by the Board, apply in the case of a
SPAC Transaction or a Direct Listing provided that all holders of at least 5% of the Company’s outstanding Common Stock (after giving effect to the conversion into Common Stock of any outstanding Preferred Stock of the Company) are subject to
substantially similar obligations with respect to such SPAC Transaction or Direct Listing, as applicable. 
 8. TRANSFER
RESTRICTIONS. In addition to any other limitation on transfer created by applicable securities laws and the restrictions in Section 11, as applicable, you will not sell, assign, hypothecate, donate, encumber or otherwise
dispose of all or any part of the shares subject to your Award or any interest in such shares except in compliance with this Agreement (including without limitation Sections 9 and 10), the Plan or the Company’s bylaws and applicable securities
laws. 
 9. RIGHT OF FIRST REFUSAL. Shares of Common
Stock issued to you pursuant to your Award are subject to any right of first refusal that may be in effect at such time the Company elects to exercise its right. 

10. RIGHT OF REPURCHASE. To the extent provided in the Company’s
bylaws in effect at such time as the Company elects to exercise its right, the Company shall have the right to repurchase all or any part of the shares of Common Stock issued to you pursuant to your Award. 

11. RESTRICTIVE LEGENDS. The shares of Common Stock issued in respect of your Award shall be endorsed with
appropriate legends as determined by the Company. 
 12. AWARD NOT AN EMPLOYMENT
OR SERVICE CONTRACT. 
 (a) Your service with the Company or an affiliate is not for any specified
term and may be terminated by you or by the Company or an affiliate at any time, for any reason, with or without cause and with or without notice. Nothing in this Agreement (including, but not limited to, the vesting of the Award pursuant to
Section 2 or the issuance of the shares subject to the Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan will: (i) confer upon you any right to continue in the employ
of, or affiliation with, the Company or an affiliate; (ii) constitute any promise or commitment by the Company or an affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or
condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company or an
affiliate of the right to terminate you at will and without regard to any future vesting opportunity that you may have. 
 (b) By accepting this
Award, you acknowledge and agree that the right to continue vesting in the Award pursuant to Section 2 and the schedule set forth in the Grant Notice is earned only by continuing as an employee, director or consultant at the will of the Company
or an affiliate (not through the act of being hired, being granted this Award or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise restructure one or
more of its businesses or affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). You further acknowledge and agree that such reorganization could result in the termination of your
Continuous Service, or the termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement, including 

  
 3 












 
but not limited to, the termination of the right to continue vesting in the Award. You further acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and the
vesting schedule set forth in the Grant Notice or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant with the
Company or an affiliate for the term of this Agreement, for any period, or at all, and will not interfere in any way with your right or the right of the Company or an affiliate to terminate your Continuous Service at any time, with or without cause
and with or without notice. 
 13. RESPONSIBILITY FOR TAXES. 

(a) You acknowledge that, regardless of any action taken by the Company, the ultimate liability for all income tax, social insurance, payroll tax,
fringe benefits tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you or deemed by the Company in its discretion to be an appropriate charge
to you even if legally applicable to the Company (“Tax-Related Items”) is and remains your responsibility and may exceed the amount actually withheld by the Company. 

(b) Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or
your employer (if not the Company) to satisfy all Tax-Related Items. In this regard, you authorize the Company or its agent to satisfy their withholding obligations with regard to all Tax-Related Items, if any, by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to you by the Company or your employer; (ii) causing you
to tender a cash payment; (iii) entering on your behalf (pursuant to this authorization without further consent) into a “same day sale” commitment with a broker dealer that is a member of the Financial Industry Regulatory Authority (a
“FINRA Dealer”) whereby you irrevocably elect to sell a portion of the shares to be delivered under the Award to satisfy the Tax-Related Items and whereby the FINRA Dealer irrevocably
commits to forward the proceeds necessary to satisfy the Tax-Related Items directly to the Company and/or its affiliates; or (iv) withholding shares of Common Stock from the shares of Common Stock issued
or otherwise issuable to you in connection with the Award with a Fair Market Value (measured as of the date shares of Common Stock are issued to you or, if and as determined by the Company, the date on which the
Tax-Related Items are required to be calculated) equal to the amount of such Tax-Related Items. The Company will use commercially reasonable efforts (as determined by
the Company) to facilitate the satisfaction of Tax-Related Items by you using one of the methods described in clauses (iii) and (iv) of the preceding sentence or by permitting you to sell shares of Common
Stock in any initial public offering by the Company. However, the Company does not guarantee that you will be able to satisfy any Tax-Related Items through any of the methods described in the preceding
sentence and in all circumstances you remain responsible for timely and fully satisfying the Tax-Related Items. Depending on the withholding method employed, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case you will receive a refund of any over-withheld
amount in cash and will have no entitlement to the Common Stock equivalent. If the obligation for Tax-Related Items is satisfied by withholding in shares of Common Stock, for tax purposes, you are deemed to
have been issued the full number of shares of Common Stock subject to the vested portion of the Award, notwithstanding that a number of the shares of Common Stock are held back solely for the purpose of paying the TaxRelated Items. 

(c) Finally, you agree to pay to the Company or your employer any amount of Tax-Related Items that the Company
or your employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by any of the means previously described. Notwithstanding any contrary provision of the Plan, the Grant Notice or of
this Agreement, if you fail to make satisfactory arrangements for the payment of any TaxRelated Items when due, you permanently will forfeit the RSUs on which the Tax-Related Items were not satisfied and will
also permanently forfeit any right to receive shares of Common Stock thereunder. In that case, the RSUs will be returned to the Company at no cost to the Company.

 14. INVESTMENT REPRESENTATIONS. In
connection with your acquisition of the Common Stock under your Award, you represent to the Company the following: 
 (a) You are aware of the
Company’s business affairs and financial condition and have acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Common Stock. You are acquiring the Common Stock for investment for
your own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act. 

(b) You understand that the Common Stock has not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of your investment intent as expressed in this Agreement. 
 (c) You further acknowledge and
understand that the Common Stock must be held indefinitely unless the Common Stock is subsequently registered under the Securities Act or an exemption from such registration is available. You further acknowledge and understand that the Company is
under no obligation to register the Common Stock. You understand that the certificate evidencing the Common Stock will be imprinted with a legend that prohibits the transfer of the Common Stock unless the Common Stock is registered or such
registration is not required in the opinion of counsel for the Company. 
 (d) You are familiar with the provisions of Rules 144 and 701 under
the Securities Act, as in effect from time to time, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of issuance of the securities, such issuance will be exempt from
registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the securities exempt under Rule 701 may be sold by you 90 days thereafter, subject
to the satisfaction of certain of the conditions specified by Rule 144 and the market stand-off agreement described in Section 7. 

(e) In the event that the sale of the Common Stock does not qualify under Rule 701 at the time of issuance, then the Common Stock may be resold by
you in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things: (i) the availability of certain public information about the Company; and (ii) the resale occurring following the required
holding period under Rule 144 after you have purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold. 
 (f)
You further understand that at the time you wish to sell the Common Stock there may be no public market upon which to make such a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public current
information requirements of Rule 144 or 701, and that, in such event, you would be precluded from selling the Common Stock under Rule 144 or 701 even if the minimum holding period requirement had been satisfied. 

15. NO OBLIGATION TO MINIMIZE TAXES. You acknowledge that the
Company is not making representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Award, including, but not limited to, the grant, vesting or
settlement of the Award, the subsequent sale of shares of Common Stock acquired pursuant to such settlement and the receipt of any dividends and/or any dividend equivalent payments. Further, you acknowledge that the Company does not have any duty or
obligation to minimize your liability for Tax-Related Items arising from the Award and will not be liable to you for any Tax-Related Items arising in connection with the
Award.

 16. NO ADVICE REGARDING
GRANT. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding your participation in the Plan, or your acquisition or sale of the
underlying shares of Common Stock. You are hereby advised to consult with your own personal tax, financial and/or legal advisors regarding the Tax-Related Items arising in connection with the Award and by
accepting the Award, you have agreed that you have done so or knowingly and voluntarily declined to do so. 
 17. UNSECURED
OBLIGATION. The Award is unfunded, and as a holder of a vested Award, you will be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares pursuant to this Agreement.
You will not have voting or any other rights as a stockholder of the Company with respect to the shares to be issued pursuant to this Agreement until such shares are issued to you pursuant to Section 5 of this Agreement. Upon such issuance, you
will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship
between you and the Company or any other person. 
 18. NOTICES. Any notices provided for in the
Grant Notice, this Agreement or the Plan will be given in writing and will be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage
prepaid, addressed to you at the last address you provided to the Company. Notwithstanding the foregoing, the Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic
means or to request your consent to participate in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an
on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

19. MISCELLANEOUS. 
 (a) As a
condition to the grant of your Award or to the Company’s issuance of any shares of Common Stock under this Agreement, the Company may require you to execute certain customary agreements entered into with the holders of capital stock of the
Company, including without limitation a right of first refusal and co-sale agreement and a stockholders agreement. 

(b) The rights and obligations of the Company under the Award will be transferable to any one or more persons or entities, and all covenants and
agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. Your rights and obligations under the Award may only be assigned with the prior written consent of the Company. 

(c) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the Company to carry out
the purposes or intent of the Award. 
 (d) You acknowledge and agree that you have reviewed the documents provided to you in relation to the Award
in their entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting the Award, and fully understand all provisions of such documents. 

(e) This Agreement will be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national
securities exchanges as may be required. 

  
 6 












 (f) All obligations of the Company under the Plan and this Agreement will be binding on any successor
to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 

20. GOVERNING PLAN DOCUMENT. The Award is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of the Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. Except
as expressly provided herein, in the event of any conflict between the provisions of the Award and those of the Plan, the provisions of the Plan will control. For purposes of the Award, a transaction or event will not constitute a Change in Control
unless the transaction or event qualifies as a change of control event within the meaning of Code Section 409A. 
 21.
SEVERABILITY. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or
the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid will, if possible, be construed in a manner which will give effect to the terms of such Section or part
of a Section to the fullest extent possible while remaining lawful and valid. 
 22. EFFECT ON OTHER
EMPLOYEE BENEFIT PLANS. The value of the Award subject to this Agreement will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any
employee benefit plan sponsored by the Company or any affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any affiliate’s employee
benefit plans. 
 23. AMENDMENT. This Agreement may not be modified, amended or terminated except by an instrument in writing,
signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which specifically states that it is amending this Agreement, so long as a copy of
such amendment is delivered to you, and provided that, except as otherwise expressly provided in the Plan, no such amendment adversely affecting your rights hereunder may be made without your written consent. Without limiting the foregoing, the
Board reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any
future law, regulation, ruling, or judicial decision, provided that any such change will be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided herein. 

24. COMPLIANCE WITH SECTION 409A OF
THE CODE. This Award is intended to comply with the “short-term deferral” rule set forth in Treasury Regulation
Section 1.409A-1(b)(4). Notwithstanding the foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise deferred compensation subject
to Section 409A, and if you are a “Specified Employee” (within the meaning set forth Section 409A(a)(2)(B)(i) of the Code) as of the date of your separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)), then the issuance of any shares that would otherwise be made upon the date of the separation from service or within the first six months thereafter will not be made on the originally
scheduled date(s) and will instead be issued in a lump sum on the date that is six months and one day after the date of the separation from service, with the balance of the shares issued thereafter in accordance with the original vesting and
issuance schedule set forth above, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that
vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2). 

  
 7 












 
Notwithstanding any contrary provision of the Plan, the Grant Notice, or of this Agreement, under no circumstances will the Company reimburse you for any taxes or other costs under
