 AUTOLUS THERAPEUTICS PLC 

2018 EQUITY INCENTIVE PLAN 
  

	1.	PURPOSE 

 The Plan’s purpose is to enhance the Company’s ability to attract,
retain and motivate persons who make (or are expected to make) important contributions to the Company by providing these individuals with equity ownership opportunities. Capitalized terms used in the Plan are defined in Section 11. 

 

	2.	ELIGIBILITY 

 Service Providers are eligible to be granted Awards under the Plan, subject
to the limitations described herein. 
  

	3.	ADMINISTRATION AND DELEGATION 

  

	3.1	Administration. 

 The Plan is administered by the Administrator. The Administrator has authority
to determine which Service Providers receive Awards, grant Awards, set Award terms and conditions, and designate whether such Awards will cover Ordinary Shares or ADSs, subject to the conditions and limitations in the Plan. The Administrator also
has the authority to take all actions and make all determinations under the Plan, to interpret the Plan and Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The Administrator
may correct defects and ambiguities, supply omissions and reconcile inconsistencies in the Plan or any Award as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the Plan are in
its sole discretion and will be final and binding on all persons having or claiming any interest in the Plan or any Award. 
  

	3.2	Appointment of Committees.  

 To the extent Applicable Laws permit, the Board may
delegate any or all of its powers under the Plan to one or more Committees or officers of the Company or any of its Subsidiaries. The Board may abolish any Committee or re-vest in itself any previously
delegated authority at any time. 
  

	3.3	Delegation to an Officer. 

 In each case to the extent Applicable Laws permit, the Board may
delegate to one or more officers the authority to do one or both of the following (i) designate Employees who are not officers to be recipients of Awards and the terms of such Awards, and (ii) determine the number of Shares to be subject to such
Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation will specify the total number of Shares that may be subject to the Awards granted by such officer and that such officer may not grant an Award
to himself or herself. Any such Awards will be granted on the form of Award Agreement most recently approved for use by the Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may not
delegate authority to an officer who is acting solely in the capacity of an officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 11.20 below. 

 

	4.	SHARES AVAILABLE FOR AWARDS 

  

	4.1	Number of Shares.  

 Subject to adjustment under Section 8 and the terms of this
Section 4, Awards may be made under the Plan in an aggregate amount up to 3,025,548 Shares (the “Share Reserve”), which number is the sum of (i) 6,778,482 new Shares, plus (ii) a number of Shares equal to the number of
shares that would otherwise remain available for future grants under the Prior Plans as of 12:01 a.m. GMT of the Plan’s effective date in Section 10.3 plus (iii) the number of shares that are subject to Prior Plan Awards that are
outstanding as of 12:01 a.m. GMT on the Plan’s effective date in Section 10.3 that may become available for issuance under the Plan in accordance with Section 4.2 from time to time. In addition, the Share Reserve will automatically increase on
October 1st of each year following the fiscal year in which the NASDAQ Listing Date occurs and ending on (and including) October 1, 2027, in an amount equal to 4% of the total number of
Shares outstanding on September 30th of the same calendar year. Notwithstanding the foregoing, the Board may act prior to October 1st of a given year to provide that there will be no
October 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of Shares than would otherwise occur pursuant to the
preceding sentence. 

  
 1 

	4.2	Share Recycling. 

 If all or any part of an Award or Prior Plan Award expires, lapses or is
terminated, exchanged for cash, surrendered, repurchased or cancelled, without having been fully exercised, or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award or Prior Plan Award at a price not
greater than the price (as adjusted to reflect any Equity Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the Award or Prior Plan Award, the unused Shares covered by the Award or Prior Plan Award will, as
applicable, become or again be available for Award grants under the Plan. Further, Shares delivered (either by actual delivery or attestation) to the Company by a Participant to satisfy the applicable exercise or purchase price of an Award or Prior
Plan Award and/or to satisfy any applicable tax withholding obligation (including Shares retained by the Company from the Award or Prior Plan Award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again
be available for Award grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards or Prior Plan Awards shall not count against the Share Reserve. 

 

	4.3	Incentive Option Limitations. 

 Notwithstanding anything to the contrary herein, no more than
14,000,000 Shares may be issued pursuant to the exercise of Incentive Options. 
  

	4.4	Substitute Awards. 

 In connection with an entity’s merger or consolidation with the
Company or the Company’s acquisition of an entity’s property or stock, the Administrator may grant Awards in substitution for any options or other equity or equity-based awards granted before such merger or consolidation by such entity or
its affiliate. Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Share Reserve (nor shall Shares subject to a
Substitute Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Options will count against the maximum number of Shares that may be issued pursuant to
the exercise of Incentive Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a
pre-existing plan approved by shareholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such
pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration
payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not
be added to the Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination. 

  
 2 

	4.5	Deed Poll. 

 The Administrator may grant Awards by entering into a deed poll and, as soon as
practicable after the Company has executed the deed poll, the Administrator shall enter into an Award Agreement. 
  

	5.	OPTIONS AND SHARE APPRECIATION RIGHTS 

  

	5.1	General. 

 The Administrator may grant Options or Share Appreciation Rights to Service Providers
subject to the limitations in the Plan, including any limitations in the Plan that apply to Incentive Options. The Administrator will determine the number of Shares covered by each Option and Share Appreciation Right, the exercise price of each
Option and Share Appreciation Right and the conditions and limitations applicable to the exercise of each Option and Share Appreciation Right. A Share Appreciation Right will entitle the Participant (or other person entitled to exercise the Share
Appreciation Right) to receive from the Company upon exercise of the exercisable portion of the Share Appreciation Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the
exercise price per Share of the Share Appreciation Right by the number of Shares with respect to which the Share Appreciation Right is exercised, subject to any limitations of the Plan or that the Administrator may impose and payable in cash, Shares
valued at Fair Market Value or a combination of the two as the Administrator may determine or provide in the Award Agreement. 
  

	5.2	Exercise Price. 

 The Administrator will establish each Option’s and Share Appreciation
Right’s exercise price and specify the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the grant date of the Option or Share Appreciation Right. 

 

	5.3	Duration. 

 Each Option or Share Appreciation Right will be exercisable at such times and as
specified in the Award Agreement, provided that the term of an Option or Share Appreciation Right will not exceed ten years. Notwithstanding the foregoing and unless determined otherwise by the Company, in the event that on the last business day of
the term of an Option or Share Appreciation Right (other than an Incentive Option) (i) the exercise of the Option or Share Appreciation Right is prohibited by Applicable Laws, as determined by the Company, or (ii) Shares may not be
purchased or sold by the applicable Participant due to any Company insider trading policy (including blackout periods) or a “lock-up” agreement undertaken in connection with an issuance of
securities by the Company, the term of the Option or Share Appreciation Right shall be extended until the date that is thirty (30) days after the end of the legal prohibition, black-out period or lock-up agreement, as determined by the Company; provided, however, in no event shall the extension last beyond the ten year term of the applicable Option or Share Appreciation Right. Notwithstanding the foregoing,
if the 

  
 3 

 Participant, prior to the end of the term of an Option or Share Appreciation Right, violates the non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, confidentiality and nondisclosure agreement or
other agreement between the Participant and the Company or any of its Subsidiaries, the right of the Participant and the Participant’s transferees to exercise any Option or Share Appreciation Right issued to the Participant shall terminate
immediately upon such violation, unless the Company otherwise determines. In addition, if, prior to the end of the term of an Option or Share Appreciation Right, the Participant is given notice by the Company or any of its Subsidiaries of the
Participant’s Termination of Service by the Company or any of its Subsidiaries for Cause, and the effective date of such Termination of Service is subsequent to the date of the delivery of such notice, the right of the Participant and the
Participant’s transferees to exercise any Option or Share Appreciation Right issued to the Participant shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise
agreed that the Participant’s service as a Service Provider will not be terminated for Cause as provided in such notice or (ii) the effective date of the Participant’s Termination of Service by the Company or any of its Subsidiaries
for Cause (in which case the right of the Participant and the Participant’s transferees to exercise any Option or Share Appreciation Right issued to the Participant will terminate immediately upon the effective date of such Termination of
Service). 
  

	5.4	Exercise. 

 Options and Share Appreciation Rights may be exercised by delivering to the Company
a written notice of exercise, in a form the Administrator approves (which may be electronic), signed by the person authorized to exercise the Option or Share Appreciation Right, together with, as applicable, payment in full (i) as specified in
Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Share Appreciation Right may not be
exercised for a fraction of a Share. 
  

	5.5	Payment Upon Exercise. 

 Subject to Section 10.8, any Company insider trading policy
(including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by: 
  

	 	(a)	cash, wire transfer of immediately available funds or by check payable to the order of the Company, provided that the Company may limit the use of one of the foregoing payment forms if one or more of the payment forms
below is permitted; 

  

	 	(b)	if there is a public market for Shares at the time of exercise, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of an irrevocable and
unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to pay the exercise price, or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional
instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to pay the exercise price; provided that such amount is paid to the Company at such time as may be required by the Administrator;

  
 4 

	 	(c)	to the extent permitted by the Administrator, delivery (either by actual delivery or attestation) of Shares owned by the Participant valued at their Fair Market Value; 

 

	 	(d)	to the extent permitted by the Administrator, surrendering Shares then issuable upon the Option’s exercise valued at their Fair Market Value on the exercise date; 

 

	 	(e)	to the extent permitted by the Administrator, delivery of a promissory note or any other property that the Administrator determines is good and valuable consideration; or 

 

	 	(f)	to the extent permitted by the Company, any combination of the above payment forms approved by the Administrator. 

  

	6.	RESTRICTED SHARES; RESTRICTED SHARE UNITS 

  

	6.1	General. 

 The Administrator may grant Restricted Shares, or the right to purchase Restricted
Shares, to any Service Provider, subject to the Company’s right to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such shares) if conditions the
Administrator specifies in the Award Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers
Restricted Share Units, which may be subject to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth in the Award Agreement the
terms and conditions for each Restricted Share and Restricted Share Unit Award, subject to the conditions and limitations contained in the Plan. 
  

	6.2	Restricted Shares. 

  

	 	(a)	Dividends. 

 Participants holding Restricted Shares will be entitled to all ordinary cash
dividends paid with respect to such Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend
or distribution to holders of Restricted Shares of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the Restricted Shares with respect to
which they were paid. 
  

	 	(b)	Certificates. 

 The Company may require that the Participant deposit in escrow with the Company
(or its designee) any certificates issued in respect of Restricted Shares, together with a stock transfer form endorsed in blank. 
  

	6.3	Restricted Share Units. 

  

	 	(a)	Settlement. 

  
 5 

 The Administrator may provide that settlement of Restricted Share Units will occur upon or as
soon as reasonably practicable after the Restricted Share Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election. 
  

	 	(b)	Shareholder Rights. 

 A Participant will have no rights of a shareholder with respect to Shares
subject to any Restricted Share Unit unless and until the Shares are delivered in settlement of the Restricted Share Unit. 
  

	 	(c)	Dividend Equivalents. 

 If the Administrator provides, a grant of Restricted Share Units may
provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares and subject to the same restrictions on transferability and
forfeitability as the Restricted Share Units with respect to which the Dividend Equivalents are granted and subject to other terms and conditions as set forth in the Award Agreement. 

 

	7.	OTHER SHARE BASED AWARDS 

 Other Share Based Awards may be granted to Participants, including Awards
entitling Participants to receive Shares to be delivered in the future (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations in the Plan. Such Other Share Based Awards will also be
available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is otherwise entitled. Other Share Based Awards may be paid in Shares or other property, as the
Administrator determines. Subject to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Share Based Award, including any purchase price, performance goal (which may be based on the Performance
Criteria), transfer restrictions, and vesting conditions, which will be set forth in the applicable Award Agreement. 
  

	8.	ADJUSTMENTS FOR CHANGES IN SHARES AND CERTAIN OTHER EVENTS 

  

	8.1	Equity Restructuring. 

 In connection with any Equity Restructuring, notwithstanding anything to
the contrary in this Section 8, the Administrator may adjust the Share Reserve and each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each
outstanding Award and/or the Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1 will be final and binding
on the affected Participant and the Company; provided that the Administrator will determine whether an adjustment is equitable. 
  

	8.2	Corporate Events. 

 In the event of any Equity Restructuring, dividend or other distribution
(whether in the form of cash, Shares, other securities, or other property), capitalization, share issue, offer, subdivision, reorganization, merger, consolidation, combination, amalgamation, repurchase,

  
 6 

	 	
recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Shares or other
securities of the Company, Change in Control, issuance of warrants or other rights to purchase Shares or other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the
Company or its financial statements or any change in any Applicable Laws or accounting principles (any “Corporate Event”), the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or
by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in Applicable Laws or accounting principles may be made within a reasonable period of time after such change) and either
automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of
the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in
Applicable Laws or accounting principles: 

  

	 	(a)	To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested
portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could have been obtained upon the exercise or settlement of the vested portion of such
Award or realization of the Participant’s rights, in any case, is equal to or less than zero (as determined by the Administrator in its discretion), then the Award may be terminated without payment. In addition, such payments under this
provision may, in the Administrator’s discretion, be delayed to the same extent that payment of consideration to the holders of Ordinary Shares in connection with the Corporate Event is delayed as a result of escrows, earn outs, holdbacks or
any other contingencies; 

  

	 	(b)	To provide that such Award shall vest and, to the extent applicable, be exercisable as to all shares covered thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award;

  

	 	(c)	To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by awards covering the equity securities of the successor or survivor
corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and/or applicable exercise or purchase price, in all cases, as determined by the Administrator; 

 

	 	(d)	To make adjustments in the number and type of shares (or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to,
adjustments of the limitations in Section 4 hereof on the maximum number and kind of shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards;

  
 7 

	 	(e)	To replace such Award with other rights or property selected by the Administrator; and/or 

  

	 	(f)	To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable transaction or event. 

The Administrator need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants.
The Administrator may take different actions with respect to the vested and unvested portions of an Award. 
  

	8.3	Administrative Stand Still. 

 In the event of any pending Corporate Event or other similar
transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to sixty days before or after such transaction. 
  

	8.4	General. 

 Except as expressly provided in the Plan or the Administrator’s action under the
Plan, no Participant will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class, issue, rights issue, offer or dissolution, liquidation, merger, or
consolidation of the Company or other corporation. Except as expressly provided with respect to an Equity Restructuring under Section 8.1 above or the Administrator’s action under the Plan, no issuance by the Company of Shares of any
class, or securities convertible into Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements
and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its
business, (ii) any Corporate Event or (iii) sale or issuance of securities, including securities with rights superior to those of the Shares or securities convertible into or exchangeable for Shares. The Administrator may treat
Participants and Awards (or portions thereof) differently under this Section 8. 
  

	9.	GENERAL PROVISIONS APPLICABLE TO AWARDS 

  

	9.1	Transferability. 

 Except as the Administrator may determine or provide in an Award Agreement or
otherwise for Awards other than Incentive Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except by will or the laws of descent and distribution, or, subject to the
Administrator’s consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, will include references
to a Participant’s authorized transferee that the Administrator specifically approves. 

  
 8 

	9.2	Documentation. 

 Each Award will be evidenced in an Award Agreement, which may be written or
electronic, as the Administrator determines. Each Award may contain terms and conditions in addition to those set forth in the Plan. 
  

	9.3	Discretion. 

 Except as the Plan otherwise provides, each Award may be made alone or in addition
or in relation to any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 

 

	9.4	Termination of Status. 

 The Administrator will determine how the disability, death, retirement,
authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which, the Participant, the Participant’s legal representative,
conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable. 
  

	9.5	Withholding. 

 Each Participant must pay the Company, or make provision satisfactory to the
Administrator for payment of, any taxes (which includes any social security contributions or the like) required by law to be withheld or paid by the Company or by an Subsidiary that is the employing entity of the Participant in connection with such
Participant’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based on the minimum statutory withholding rates (or such other rate as may be determined by
the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a Participant. Subject to Section 10.8 and any Company insider trading policy (including blackout periods), Participants may
satisfy such tax obligations (i) in cash, by wire transfer of immediately available funds, by check made payable to the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the
payment forms below is permitted, (ii) to the extent permitted by the Administrator, in whole or in part by delivery of Shares, including Shares retained from the Award creating the tax obligation, valued at their Fair Market Value,
(iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of an irrevocable and
unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional
instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding, provided that such amount is paid to the Company at such time as may be required by the Administrator,
or (iv) to the extent permitted by the Company, any combination of the foregoing payment forms approved by the Administrator. If any tax withholding obligation will be satisfied under clause (ii) of the immediately preceding sentence by
the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company may elect to instruct any brokerage firm determined acceptable to the
Company for such purpose to sell on the applicable Participant’s behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an Award under the Plan
will constitute the Participant’s authorization to the Company and instruction and authorization to such brokerage firm to complete the transactions described in this sentence. 

  
 9 

	9.6	Amendment of Award; Repricing. 

 The Administrator may amend, modify or terminate any
outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Option to a Non-Qualified Option. The
Participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the Participant’s rights under the Award, or (ii) the change is
permitted under Section 8 or pursuant to Section 10.6. Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may not, except pursuant to Section 8, without the approval of the shareholders of the Company,
reduce the exercise price per share of outstanding Options or Share Appreciation Rights or cancel outstanding Options or Share Appreciation Rights in exchange for cash, other Awards or Options or Share Appreciation Rights with an exercise price per
share that is less than the exercise price per share of the original Options or Share Appreciation Rights. 
  

	9.7	Conditions on Delivery of Shares. 

 The Company will not be obligated to deliver any Shares
under the Plan or remove restrictions from Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all other legal matters
regarding the issuance and delivery of such Shares (including payment of nominal value) have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has
executed and delivered to the Company such representations or agreements as the Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having
jurisdiction, which the Administrator determines is necessary to the lawful issuance and sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been
obtained. 
  

	9.8	Acceleration. 

 The Administrator may at any time provide that any Award will become immediately
vested and fully or partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable. 
  

	9.9	Additional Terms of Incentive Options. 

 The Administrator may grant Incentive Options only to
employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to receive Incentive
Options under the Code. If an Incentive Option is granted to a Greater Than 10% Shareholder, the exercise price will not be less than 110% of the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five
years. All Incentive Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive Option, the Participant agrees to give prompt notice to the Company of

  
 10 

 
dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or
(ii) one year after the transfer of such Shares to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in
such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Participant, or any other party, if an Incentive Option fails or ceases to qualify as an “incentive stock option” under Section 422 of
the Code. Any Incentive Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares having a fair market value
exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Option. 

 

	10.	MISCELLANEOUS 

  

	10.1	No Right to Employment or Other Status. 

 No person will have any claim or right to be granted
an Award, and the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate
its relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an Award Agreement. 
  

	10.2	No Rights as Shareholder; Certificates. 

 Subject to the Award Agreement, no Participant or
Designated Beneficiary will have any rights as a shareholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the Plan, unless the Administrator
otherwise determines or Applicable Laws require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded in the books of the Company
(or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with Applicable Laws. 

 

	10.3	Effective Date and Term of Plan. 

 Unless earlier terminated by the Board, the Plan will become
effective on the day prior to the NASDAQ Listing Date and will remain in effect until the tenth anniversary of the effective date, but Awards previously granted may extend beyond that date in accordance with the Plan. If the Plan is not approved by
the Company’s shareholders, the Plan will not become effective, no Awards will be granted under the Plan and the Prior Plans will continue in full force and effect in accordance with their terms. No Incentive Option may be granted after the
tenth anniversary of the earlier of (i) the date the Plan is adopted by the Board or (ii) the date the Plan is approved by the Company’s shareholders. 
  

	10.4	Amendment of Plan. 

 The Administrator may amend, suspend or terminate the Plan at any time;
provided that no amendment, other than an increase to the Share Reserve, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted under the Plan
during any suspension period or after Plan termination. Awards outstanding at the time of any Plan suspension or 

  
 11 

 
termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or termination. The Board will obtain shareholder approval of any Plan amendment
to the extent necessary to comply with Applicable Laws. 
  

	10.5	Provisions for Foreign Participants. 

 The Administrator may modify Awards granted to
Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax,
securities, currency, employee benefit or other matters. 
  

	10.6	Section 409A. 

 The following provisions only apply to Participants subject to tax in the
United States. 
  

	 	(a)	General. 

 The Company intends that all Awards be structured to comply with, or be exempt from,
Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent,
amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any
such actions intended to (A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an
Award’s grant date. The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to avoid the taxes,
penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant
“nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A. 
  

	 	(b)	Separation from Service. 

 If an Award constitutes “nonqualified deferred
compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the
Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s Service Provider relationship. For
purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a “separation from service.” 

  
 12 

	 	(c)	Payments to Specified Employees. 

 Notwithstanding any contrary provision in the Plan or any
Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her
“separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period immediately following such
“separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six-month
period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six months following the Participant’s “separation from
service” will be paid at the time or times the payments are otherwise scheduled to be made. 
  

	10.7	Limitations on Liability. 

 Notwithstanding any other provisions of the Plan, no individual
acting as a director, officer, other employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection
with the Plan or any Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator, director, officer, other employee or agent of the
Company or any Subsidiary. The Company will indemnify and hold harmless each director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or delegated any duty or power relating to the Plan’s
administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission concerning this
Plan unless arising from such person’s own fraud or bad faith. 
  

	10.8	Lock-Up Period. 

 The Company may, at the request of any
underwriter representative or otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly, selling or otherwise transferring any Shares or other
Company securities during a period of up to one hundred eighty days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter. 

 

	10.9	Data Privacy. 

 For the purpose of operating the Plan in the European Union, the Company will
collect and process information relating to Participants in accordance with the privacy notice which is provided to each Participant. 
  

	10.10	Severability. 

 If any portion of the Plan or any action taken under it is held illegal or
invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be
null and void. 

  
 13 

	10.11	Governing Documents. 

 If any contradiction occurs between the Plan and any Award Agreement or
other written agreement between a Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision
of the Plan will not apply. 
  

	10.12	Governing Law. 

 The Plan and all Awards will be governed by and interpreted in accordance with
the laws of the United Kingdom, disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws other than the United
Kingdom. 
  

	10.13	Claw-back Provisions. 

 All Awards (including any proceeds, gains or other economic benefit the
Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to any Company claw-back policy, including any claw-back policy adopted to comply with
Applicable Laws (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as set forth in such claw-back policy or the Award Agreement. 

 

	10.14	Titles and Headings. 

 The titles and headings in the Plan are for convenience of reference only
and, if any conflict, the Plan’s text, rather than such titles or headings, will control. 
  

	10.15	Conformity to Securities Laws. 

 Participant acknowledges that the Plan is intended to conform
to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award
Agreements will be deemed amended as necessary to conform to Applicable Laws. 
  

	10.16	Relationship to Other Benefits. 

 No payment under the Plan will be taken into account in
determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as expressly provided in writing in such other plan or an agreement thereunder.

  

	10.17	Broker-Assisted Sales. 

 In the event of a broker-assisted sale of Shares in connection with the
payment of amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (a) any Shares to be sold through the broker-assisted sale will be sold on the day
the payment first becomes due, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an average price; (c) the applicable
Participant will be 

  
 14 

 
responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or
expenses relating to any such sale; (d) to the extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably
practicable; (e) the Company and its designees are under no obligation to arrange for such sale at any particular price; and (f) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable
obligation, the Participant may be required to pay immediately upon demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation.

 The Option will vest and become exercisable according to the
vesting schedule in the Grant Notice (the “Vesting Schedule”) except that any fraction of a Share as to which the Option would be vested or exercisable will be accumulated and will vest and become exercisable only when a whole Share
has accumulated. Notwithstanding anything in the Grant Notice, the Plan or this Agreement to the contrary, unless the Administrator otherwise determines, the Option will immediately expire and be forfeited as to any portion that is not vested and
exercisable as of Participant’s Termination of Service for any reason. 
  

	2.2	Duration of Exercisability. 

 The Vesting Schedule is cumulative. Any portion of the Option
which vests and becomes exercisable will remain vested and exercisable until the Option expires. The Option will be forfeited immediately upon its expiration. 
  

	2.3	Expiration of Option. 

 The Option may not be exercised to any extent by anyone after, and will
expire on, the first of the following to occur: 
  

	 	(a)	The final expiration date in the Grant Notice; 

  

	 	(b)	Except as the Administrator may otherwise approve, the expiration of three (3) months from the date of Participant’s Termination of Service, unless Participant’s Termination of Service is for Cause or by
reason of Participant’s death or Disability; 

  
 21 

	 	(c)	Except as the Administrator may otherwise approve, the expiration of one (1) year from the date of Participant’s Termination of Service by reason of Participant’s death or Disability; and

  

	 	(d)	Except as the Administrator may otherwise approve, Participant’s Termination of Service for Cause. 

  

	3.	EXERCISE OF OPTION 

  

	3.1	Person Eligible to Exercise. 

 During Participant’s lifetime, only Participant may exercise
the Option. After Participant’s death, any exercisable portion of the Option may, prior to the time the Option expires, be exercised by Participant’s Designated Beneficiary as provided in the Plan. 

 

	3.2	Partial Exercise. 

 Any exercisable portion of the Option or the entire Option, if then wholly
exercisable, may be exercised, in whole or in part, according to the procedures in the Plan at any time prior to the time the Option or portion thereof expires, except that the Option may only be exercised for whole Shares. 

 

	3.3	Tax Withholding. 

  

	 	(a)	The Company has the right and option, but not the obligation, to treat Participant’s failure to provide timely payment in accordance with the Plan of any withholding tax arising in connection with the Option as
Participant’s election to satisfy all or any portion of the withholding tax by requesting the Company retain Shares otherwise issuable under the Option. 

  

	 	(b)	Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the Option, regardless of any action the Company or any Subsidiary takes with respect to any tax
withholding obligations that arise in connection with the Option. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or exercise of
the Option or the subsequent sale of Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure the Option to reduce or eliminate Participant’s tax liability. 

 

	4.	OTHER PROVISIONS 

  

	4.1	Adjustments. 

 Participant acknowledges that the Option is subject to adjustment, modification
and termination in certain events as provided in this Agreement and the Plan. 
  

	4.2	Notices. 

 Any notice to be given under the terms of this Agreement to the Company must be in
writing and addressed to the Company in care of the Company’s Secretary at the Company’s principal office or the Secretary’s then-current email address or facsimile number. Any notice 

  
 22 

 
to be given under the terms of this Agreement to Participant must be in writing and addressed to Participant (or, if Participant is then deceased, to the person entitled to exercise the Option)
at Participant’s last known mailing address, email address or facsimile number in the Company’s personnel files. By a notice given pursuant to this Section, either party may designate a different address for notices to be given to that
party. Any notice will be deemed duly given when actually received, when sent by email, when sent by certified mail (return receipt requested) and deposited with postage prepaid in a post office or branch post office regularly maintained by the
United States Postal Service, when delivered by a nationally recognized express shipping company or upon receipt of a facsimile transmission confirmation. 
  

	4.3	Titles. 

 Titles are provided herein for convenience only and are not to serve as a basis for
interpretation or construction of this Agreement. 
  

	4.4	Conformity to Securities Laws. 

 Participant acknowledges that the Plan, the Grant Notice and
this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed amended as necessary to conform to Applicable Laws. 

 

	4.5	Successors and Assigns. 

 The Company may assign any of its rights under this Agreement to
single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in the Plan, this Agreement will be binding upon and inure to the benefit of
the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
  

	4.6	Limitations Applicable to Section 16 Persons. 

 Notwithstanding any other provision of the
Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement and the Option will be subject to any additional limitations set forth in any applicable exemptive rule under
Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule. To the extent Applicable Laws permit, this Agreement will be
deemed amended as necessary to conform to such applicable exemptive rule. 
  

	4.7	Entire Agreement. 

 The Plan, the Grant Notice and this Agreement (including any
exhibit hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 

 

	4.8	Agreement Severable. 

 In the event that any provision of the Grant Notice or this Agreement is
held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 

  
 23 

	4.9	Limitation on Participant’s Rights. 

 Participation in the Plan confers no rights or
interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of
itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Option, and rights no greater than the right to receive
the Shares as a general unsecured creditor with respect to the Option, as and when exercised pursuant to the terms hereof. 
  

	4.10	Not a Contract of Employment. 

 Nothing in the Plan, the Grant Notice or this Agreement confers
upon Participant any right to continue in the employ or service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or
terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

 

	4.11	Counterparts. 

 The Grant Notice may be executed in one or more counterparts, including by way
of any electronic signature, subject to Applicable Laws, each of which will be deemed an original and all of which together will constitute one instrument. 
  

	4.12	Incentive Options. 

 If the Option is designated as an Incentive Option: 

 

	 	(a)	Participant acknowledges that to the extent the aggregate fair market value of shares (determined as of the time the option with respect to the shares is granted) with respect to which options intended to qualify as
“incentive stock options” under Section 422 of the Code, including the Option, are exercisable for the first time by Participant during any calendar year exceeds $100,000 or if for any other reason such options do not qualify or cease
to qualify for treatment as “incentive stock options” under Section 422 of the Code, such options (including the Option) will be treated as non-qualified options. Participant further
acknowledges that the rule set forth in the preceding sentence will be applied by taking the Option and other options into account in the order in which they were granted, as determined under Section 422(d) of the Code. Participant
also acknowledges that if the Option is exercised more than three (3) months after Participant’s Termination of Service, other than by reason of death or disability, the Option will be taxed as a
Non-Qualified Option. 

  
 24 

	 	(b)	Participant will give prompt written notice to the Company of any disposition or other transfer of any Shares acquired under this Agreement if such disposition or other transfer is made (a) within two
(2) years from the Grant Date or (b) within one (1) year after the transfer of such Shares to Participant. Such notice will specify the date of such disposition or other transfer and the amount realized, in cash, other property,
assumption of indebtedness or other consideration, by Participant in such disposition or other transfer.

 Exhibit A 

RESTRICTED SHARE AGREEMENT 
 Capitalized
terms not specifically defined in this Agreement have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan. 
  

	1.	GENERAL 

  

	1.1	Issuance of Restricted Shares. 

 In consideration for payment of at least the nominal value, the
Company will issue the Restricted Shares to the Participant effective as of the grant date set forth in the Grant Notice and will cause (a) a certificate or certificates representing the Restricted Shares to be registered in Participant’s
name or (b) the Restricted Shares to be held in book-entry form. If a certificate representing the Restricted Shares is issued, the certificate will be delivered to, and held in accordance with this Agreement by, the Company or its authorized
representatives and will bear the restrictive legends required by this Agreement. If the Restricted Shares are held in book-entry form, then the book-entry will indicate that the Restricted Shares are subject to the restrictions of this Agreement.

  

	1.2	Incorporation of Terms of Plan. 

 The Restricted Shares are subject to the terms and conditions
set forth in this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control. 

 

	2.	VESTING, FORFEITURE AND ESCROW 

  

	2.1	Vesting. 

 The Restricted Shares will become vested Shares (the “Vested
Shares”) according to the vesting schedule in the Grant Notice except that any fraction of a Share that would otherwise become a Vested Share will be accumulated and will become a Vested Share only when a whole Vested Share has accumulated.

  

	2.2	Forfeiture. 

 In the event of Participant’s Termination of Service for any reason,
Participant will immediately and automatically forfeit to the Company any Shares that are not Vested Shares (the “Unvested Shares”) at the time of Participant’s Termination of Service, except as otherwise determined by the
Administrator or provided in a binding written agreement between Participant and the Company. Upon forfeiture of Unvested Shares, the Company will become the legal and beneficial owner of the Unvested Shares and all related interests and Participant
will have no further rights with respect to the Unvested Shares. 
  

	2.3	Escrow. 

  

	 	(a)	 Unvested Shares will be held by the Company or its authorized representatives until (i) they are forfeited,
(ii) they become Vested Shares or (iii) this Agreement is no longer in effect. By accepting this Award, Participant appoints the Company and its 

  
 28 

	 	
authorized representatives as Participant’s attorney(s)-in-fact to take all actions necessary to effect any
transfer of forfeited Unvested Shares (and Retained Distributions (as defined below), if any, paid on such forfeited Unvested Shares) to the Company as may be required pursuant to the Plan or this Agreement and to execute such representations or
other documents or assurances as the Company or such representatives deem necessary or advisable in connection with any such transfer. The Company, or its authorized representative, will not be liable for any good faith act or omission with respect
to the holding in escrow or transfer of the Restricted Shares. 

  

	 	(b)	All cash dividends and other distributions made or declared with respect to Unvested Shares (“Retained Distributions”) will be held by the Company until the time (if ever) when the Unvested Shares to
which such Retained Distributions relate become Vested Shares. The Company will establish a separate Retained Distribution bookkeeping account (“Retained Distribution Account”) for each Unvested Share with respect to which Retained
Distributions have been made or declared in cash and credit the Retained Distribution Account (without interest) on the date of payment with the amount of such cash made or declared with respect to the Unvested Share. Retained Distributions
(including any Retained Distribution Account balance) will immediately and automatically be forfeited upon forfeiture of the Unvested Share with respect to which the Retained Distributions were paid or declared. 

 

	 	(c)	As soon as reasonably practicable following the date on which an Unvested Share becomes a Vested Share, the Company will (i) cause the certificate (or a new certificate without the legend required by this
Agreement, if Participant so requests) representing the Share to be delivered to Participant or, if the Share is held in book-entry form, cause the notations indicating the Share is subject to the restrictions of this Agreement to be removed and
(ii) pay to Participant the Retained Distributions relating to the Share. 

  

	2.4	Rights as Shareholder. 

 Except as otherwise provided in this Agreement or the Plan, upon
issuance of the Restricted Shares by the Company, Participant will have all the rights of a shareholder with respect to the Restricted Shares, including the right to vote the Restricted Shares and to receive dividends or other distributions paid or
made with respect to the Restricted Shares. 
  

	3.	TAXATION AND TAX WITHHOLDING 

  

	3.1	Representation. 

 Participant represents to the Company that Participant has reviewed with
Participant’s own tax advisors the tax consequences of the Restricted Shares and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations
of the Company or any of its agents. 

  
 29 

	3.2	Section 83(b) Election. 

 If Participant makes an election under
Section 83(b) of the Code with respect to the Restricted Shares, Participant will deliver a copy of the election to the Company promptly after filing the election with the Internal Revenue Service. 

 

	3.3	Tax Withholding. 

  

	 	(a)	On each vesting date, and on or before the Restricted Shares vest, and at any other time as reasonably requested by the Company in accordance with applicable tax laws (including, without limitation, in connection with
the payment of any Retained Distributions), Participant hereby authorizes any required withholding from the shares issuable to Participant and/or otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state,
local and foreign tax withholding obligations of the Company or any parent or subsidiary that arise in connection with Participant’s Restricted Shares (the “Withholding Taxes”). Specifically, pursuant to Section 3.3(b),
Participant has agreed to a “same day sale” commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby Participant has irrevocably agreed to sell a portion of
the shares in connection with Participant’s Restricted Shares to satisfy the Withholding Taxes and whereby the FINRA Dealer committed to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its parents
or subsidiaries. If, for any reason, such “same day sale” commitment pursuant to Section 3.3(b) does not result in sufficient proceeds to satisfy the Withholding Taxes or would be prohibited by Applicable Laws at the applicable time,
Participant hereby authorizes the Company and/or the relevant parent or subsidiary, or their respective agents, at their discretion, to satisfy the obligations with regard to all Withholding Taxes by one or a combination of the following:
(i) withholding from any compensation otherwise payable to Participant by the Company or any parent or subsidiary; (ii) causing Participant to tender a cash payment (which may be in the form of a check, electronic wire transfer or other
method permitted by the Company); or (iii) withholding shares from the shares issued or otherwise issuable to Participant in connection with Participant’s Restricted Shares with a fair market value (measured as of the date shares are
issued to Participant) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares so withheld will not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the
minimum statutory withholding rates for federal, state, local and, if applicable, foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and, provided, further, that to the extent necessary to qualify for
an exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the prior approval of the Company’s Compensation Committee. 

 

	 	(b)	Participant hereby acknowledges and agrees to the following: 

  

	 	(i)	Participant hereby appoints such FINRA Dealer appointed by the Company for purposes of this Section 3.3(b) as Participant’s agent (the “Agent”), and authorize the Agent: 

  
 30 

	 	(A)	To sell on the open market at the then prevailing market price(s), on Participant’s behalf, as soon as practicable on or after each date on which the shares underlying Participant’s Restricted Shares vest, the
number (rounded up to the next whole number) of the shares to be delivered to Participant in connection with the vesting of those shares sufficient to generate proceeds to cover (A) the Withholding Taxes that Participant is required to pay
pursuant to the Plan and this Agreement as a result of the shares vesting (or being issued, as applicable) and (B) all applicable fees and commissions due to, or required to be collected by, the Agent with respect thereto; and

  

	 	(B)	To remit any remaining funds to Participant. 

  

	 	(ii)	Participant hereby authorizes the Company and the Agent to cooperate and communicate with one another to determine the number of shares that must be sold pursuant to this Section 3.3(b). 

 

	 	(iii)	Participant understands that the Agent may effect sales as provided in this Section 3.3(b) in one or more sales and that the average price for executions resulting from bunched orders will be assigned to
Participant’s account. In addition, Participant acknowledges that it may not be possible to sell shares underlying Participant’s Restricted Shares as provided by in this Section 3.3(b) due to (A) a legal or contractual
restriction applicable to Participant or the Agent, (B) a market disruption, or (C) rules governing order execution priority on the national exchange where the shares may be traded. In the event of the Agent’s inability to sell shares
underlying Participant’s Restricted Shares, Participant will continue to be responsible for the timely payment to the Company of all Withholding Taxes and any other federal, state, local and foreign taxes that are required by Applicable Laws
and regulations to be withheld, including but not limited to those amounts specified in this Section 3.3(b). 

  

	 	(iv)	Participant acknowledges that regardless of any other term or condition of this Section 3.3(b), the Agent will not be liable to Participant for (A) special, indirect, punitive, exemplary, or consequential
damages, or incidental losses or damages of any kind, or (B) any failure to perform or for any delay in performance that results from a cause or circumstance that is beyond its reasonable control. 

 

	 	(v)	Participant hereby agrees to execute and deliver to the Agent any other agreements or documents as the Agent reasonably deems necessary or appropriate to carry out the purposes and intent of this Section 3.3(b).
The Agent is a third-party beneficiary of this Section 3.3(b). 

  

	 	(vi)	Participant hereby agrees that if Participant has signed the Grant Notice at a time that Participant is in possession of material non-public information, unless Participant
informs the Company in writing within five business days following the date Participant ceases to be in possession of material non-public information that Participant is not in agreement with the provisions of
this Section 3.3(b), Participant not providing such written determination shall be a determination and agreement that Participant has agreed to the provisions set forth in this Section 3.3(b) on such date as Participant has ceased to be in
possession of material non-public information. 

  
 31 

	 	(i)	This Section 3.3(b) shall terminate not later than the date on which all withholding taxes arising in connection with the vesting of Participant’s Restricted Shares have been satisfied. 

 

	 	(c)	Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the Restricted Shares, regardless of any action the Company or any Subsidiary takes with respect to
any tax withholding obligations that arise in connection with the Restricted Shares. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding,
vesting or payment of the Restricted Shares or the subsequent sale of the Restricted Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure this Award to reduce or eliminate Participant’s tax liability.

  

	4.	RESTRICTIVE LEGENDS AND TRANSFERABILITY 

  

	4.1	Legends. 

 Any certificate representing a Restricted Share will bear the following legend until
the Restricted Share becomes a Vested Share: 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE IN FAVOR OF THE COMPANY
AND MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF A RESTRICTED SHARE AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

 

	4.2	Transferability. 

 The Restricted Shares and any Retained Distributions are subject to the
restrictions on transfer in the Plan and may not be sold, assigned or transferred in any manner unless and until they become Vested Shares. Any attempted transfer or disposition of Unvested Shares or related Retained Distributions prior to the time
the Unvested Shares become Vested Shares will be null and void. The Company will not be required to (a) transfer on its books any Restricted Share that has been sold or otherwise transferred in violation of this Agreement or (b) treat as
owner of such Restricted Share or accord the right to vote or pay dividends to any purchaser or other transferee to whom such Restricted Share has been so transferred. The Company may issue appropriate “stop transfer” instructions
to its transfer agent, if any, or make appropriate notations to the same effect in its records. 
  

	5.	OTHER PROVISIONS 

  

	5.1	Adjustments. 

 Participant acknowledges that the Restricted Shares are subject to adjustment,
modification and termination in certain events as provided in this Agreement and the Plan. 

  
 32 

	5.2	Notices. 

 Any notice to be given under the terms of this Agreement to the Company must be in
writing and addressed to the Company in care of the Company’s Secretary at the Company’s principal office or the Secretary’s then-current email address or facsimile number. Any notice to be given under the terms of this Agreement to
Participant must be in writing and addressed to Participant at Participant’s last known mailing address, email address or facsimile number in the Company’s personnel files. By a notice given pursuant to this Section, either party may
designate a different address for notices to be given to that party. Any notice will be deemed duly given when actually received, when sent by email, when sent by certified mail (return receipt requested) and deposited with postage prepaid in a post
office or branch post office regularly maintained by the United States Postal Service, when delivered by a nationally recognized express shipping company or upon receipt of a facsimile transmission confirmation. 

 

	5.3	Titles. 

 Titles are provided herein for convenience only and are not to serve as a basis for
interpretation or construction of this Agreement. 
  

	5.4	Conformity to Securities Laws. 

 Participant acknowledges that the Plan, the Grant Notice and
this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed amended as necessary to conform to Applicable Laws. 

 

	5.5	Successors and Assigns. 

 The Company may assign any of its rights under this Agreement to
single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in this Agreement or the Plan, this Agreement will be binding upon and inure
to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
  

	5.6	Limitations Applicable to Section 16 Persons. 

 Notwithstanding any other provision of the
Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement and the Restricted Shares will be subject to any additional limitations set forth in any applicable exemptive
rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule. To the extent Applicable Laws permit, this
Agreement will be deemed amended as necessary to conform to such applicable exemptive rule. 
  

	5.7	Entire Agreement. 

 The Plan, the Grant Notice and this Agreement (including any
exhibit hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 

  
 33 

	5.8	Agreement Severable. 

 In the event that any provision of the Grant Notice or this Agreement is
held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 

 

	5.9	Limitation on Participant’s Rights. 

 Participation in the Plan confers no rights or
interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of
itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Award. 

 

	5.10	Not a Contract of Employment.

 Exhibit A 

PERFORMANCE RESTRICTED SHARE UNIT AGREEMENT 

Capitalized terms not specifically defined in this Agreement have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the
Plan. 
  

	1.	GENERAL 

  

	1.1	Award of PRSUs and Dividend Equivalents. 

  

	 	(a)	The Company has granted the PRSUs to Participant effective as of the grant date set forth in the Grant Notice (the “Grant Date”). Each PRSU represents the right to receive one Share or, at the
option of the Company, an amount of cash, in either case, as set forth in this Agreement. Participant will have no right to the distribution of any Shares or payment of any cash until the time (if ever) the PRSUs have vested. 

 

	 	(b)	The Company hereby grants to Participant, with respect to each PRSU, a Dividend Equivalent for ordinary cash dividends paid to substantially all holders of outstanding Shares with a record date after the Grant Date and
prior to the date the applicable PRSU is settled, forfeited or otherwise expires. Each Dividend Equivalent entitles Participant to receive the equivalent value of any such ordinary cash dividends paid on a single Share. The Company will establish a
separate Dividend Equivalent bookkeeping account (a “Dividend Equivalent Account”) for each Dividend Equivalent and credit the Dividend Equivalent Account (without interest) on the applicable dividend payment date with the
amount of any such cash paid. 

  

	1.2	Incorporation of Terms of Plan. 

 The PRSUs are subject to the terms and conditions set forth in
this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control. 

 

	1.3	Unsecured Promise. 

 The PRSUs and Dividend Equivalents will at all times prior to settlement
represent an unsecured Company obligation payable only from the Company’s general assets. 
  

	2.	VESTING; FORFEITURE AND SETTLEMENT 

  

	2.1	Vesting; Forfeiture. 

 The PRSUs will vest according to the vesting schedule in the Grant Notice
except that any fraction of a PRSU that would otherwise be vested will be accumulated and will vest only when a whole PRSU has accumulated. In the event of Participant’s Termination of Service for any reason, all unvested PRSUs will immediately
and automatically be cancelled and forfeited, except as otherwise determined by the Administrator or provided in a binding written agreement between Participant and the Company. Dividend Equivalents (including any Dividend Equivalent Account
balance) will vest or be forfeited, as applicable, upon the vesting or forfeiture of the PRSU with respect to which the Dividend Equivalent (including the Dividend Equivalent Account) relates. 

  
 37 

	2.2	Settlement. 

  

	 	(a)	PRSUs and Dividend Equivalents (including any Dividend Equivalent Account balance) will be paid in Shares or cash at the Company’s option as soon as administratively practicable after the vesting of the applicable
PRSU, but in no event more than sixty (60) days after the PRSU’s vesting date. Notwithstanding the foregoing, the Company may delay any payment under this Agreement that the Company reasonably determines would violate Applicable Laws until
the earliest date the Company reasonably determines the making of the payment will not cause such a violation. 

  

	 	(b)	If a PRSU is paid in cash, the amount of cash paid with respect to the PRSU will equal the Fair Market Value of a Share on the day immediately preceding the payment date. If a Dividend Equivalent is paid in Shares, the
number of Shares paid with respect to the Dividend Equivalent will equal the quotient, rounded down to the nearest whole Share, of the Dividend Equivalent Account balance divided by the Fair Market Value of a Share on the day immediately preceding
the payment date. 

  

	 	(c)	If a PRSU is paid in Shares, Participant may be required to pay the nominal value thereof in the same manner as provided for Withholding Taxes below. 

 

	3.	TAXATION AND TAX WITHHOLDING 

  

	3.1	Representation. 

 Participant represents to the Company that Participant has reviewed with
Participant’s own tax advisors the tax consequences of this Award and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the
Company or any of its agents. 
  

	3.2	Tax Withholding. 

  

	 	(a)	 On each vesting date, and on or before the time Participant receives a distribution of the shares underlying the
PRSUs, and at any other time as reasonably requested by the Company in accordance with applicable tax laws (including, without limitation, in connection with the payment of any Dividend Equivalent), Participant hereby authorizes any required
withholding from the shares issuable to Participant and/or otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any parent or
subsidiary that arise in connection with Participant’s PRSU (the “Withholding Taxes”). Specifically, pursuant to Section 3.2(b), Participant has agreed to a “same day sale” commitment with a broker-dealer that is
a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby Participant has irrevocably agreed to sell a portion of the shares to be delivered in connection with Participant’s PRSUs to satisfy the
Withholding Taxes and whereby the FINRA Dealer committed to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its parents or subsidiaries. If, for any reason, such

  
 38 

	 	
“same day sale” commitment pursuant to Section 3.2(b) does not result in sufficient proceeds to satisfy the Withholding Taxes or would be prohibited by Applicable Laws at the
applicable time, Participant hereby authorizes the Company and/or the relevant parent or subsidiary, or their respective agents, at their discretion, to satisfy the obligations with regard to all Withholding Taxes by one or a combination of the
following: (i) withholding from any compensation otherwise payable to Participant by the Company or any parent or subsidiary; (ii) causing Participant to tender a cash payment (which may be in the form of a check, electronic wire transfer
or other method permitted by the Company); or (iii) withholding shares from the shares issued or otherwise issuable to Participant in connection with Participant’s PRSUs with a fair market value (measured as of the date shares are issued
to Participant) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares so withheld will not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum
statutory withholding rates for federal, state, local and, if applicable, foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and, provided, further, that to the extent necessary to qualify for an
exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the prior approval of the Company’s Compensation Committee. 

 

	 	(b)	Participant hereby acknowledges and agrees to the following: 

  

	 	(i)	Participant hereby appoints such FINRA Dealer appointed by the Company for purposes of this Section 3.2(b) as Participant’s agent (the “Agent”), and authorize the Agent: 

 

	 	(A)	To sell on the open market at the then prevailing market price(s), on Participant’s behalf, as soon as practicable on or after each date on which the shares underlying Participant’s PRSUs vest, the number
(rounded up to the next whole number) of the shares to be delivered to Participant in connection with the vesting of those shares sufficient to generate proceeds to cover (A) the Withholding Taxes that Participant is required to pay pursuant to
the Plan and this Agreement as a result of the shares vesting (or being issued, as applicable) and (B) all applicable fees and commissions due to, or required to be collected by, the Agent with respect thereto; and 

 

	 	(B)	To remit any remaining funds to Participant. 

  

	 	(ii)	Participant hereby authorizes the Company and the Agent to cooperate and communicate with one another to determine the number of shares that must be sold pursuant to this Section 3.2(b). 

 

	 	(iii)	 Participant understands that the Agent may effect sales as provided in this Section 3.2(b) in one or more
sales and that the average price for executions resulting from bunched orders will be assigned to Participant’s account. In addition, Participant acknowledges that it may not be possible to sell shares underlying Participant’s PRSUs as
provided by in this Section 3.2(b) due to (A) a legal or contractual restriction applicable to Participant or the Agent, (B) 

  
 39 

	 	
a market disruption, or (C) rules governing order execution priority on the national exchange where the shares may be traded. In the event of the Agent’s inability to sell shares
underlying Participant’s PRSUs, Participant will continue to be responsible for the timely payment to the Company of all Withholding Taxes and any other federal, state, local and foreign taxes that are required by Applicable Laws and
regulations to be withheld, including but not limited to those amounts specified in this Section 3.2(b). 

  

	 	(iv)	Participant acknowledges that regardless of any other term or condition of this Section 3.2(b), the Agent will not be liable to Participant for (A) special, indirect, punitive, exemplary, or consequential
damages, or incidental losses or damages of any kind, or (B) any failure to perform or for any delay in performance that results from a cause or circumstance that is beyond its reasonable control. 

 

	 	(v)	Participant hereby agrees to execute and deliver to the Agent any other agreements or documents as the Agent reasonably deems necessary or appropriate to carry out the purposes and intent of this Section 3.2(b).
The Agent is a third-party beneficiary of this Section 3.2(b). 

  

	 	(vi)	Participant hereby agrees that if Participant has signed the Grant Notice at a time that Participant is in possession of material non-public information, unless Participant
informs the Company in writing within five business days following the date Participant ceases to be in possession of material non-public information that Participant is not in agreement with the provisions of
this Section 3.2(b), Participant not providing such written determination shall be a determination and agreement that Participant has agreed to the provisions set forth in this Section 3.2(b) on such date as Participant has ceased to be in
possession of material non-public information. 

  

	 	(vii)	This Section 3.2(b) shall terminate not later than the date on which all withholding taxes arising in connection with the vesting of Participant’s PRSUs have been satisfied. 

 

	 	(c)	Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the PRSUs and the Dividend Equivalents, regardless of any action the Company or any Subsidiary takes
with respect to any tax withholding obligations that arise in connection with the PRSUs or Dividend Equivalents. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in
connection with the awarding, vesting or payment of the PRSUs or the Dividend Equivalents or the subsequent sale of Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure the PRSUs or Dividend Equivalents to
reduce or eliminate Participant’s tax liability. 

  
 40 

	4.	OTHER PROVISIONS 

  

	4.1	Adjustments. 

 Participant acknowledges that the PRSUs, the Shares subject to the PRSUs and the
Dividend Equivalents are subject to adjustment, modification and termination in certain events as provided in this Agreement and the Plan. 
  

	4.2	Notices. 

 Any notice to be given under the terms of this Agreement to the Company must be in
writing and addressed to the Company in care of the Company’s Secretary at the Company’s principal office or the Secretary’s then-current email address or facsimile number. Any notice to be given under the terms of this Agreement to
Participant must be in writing and addressed to Participant at Participant’s last known mailing address, email address or facsimile number in the Company’s personnel files. By a notice given pursuant to this Section, either party may
designate a different address for notices to be given to that party. Any notice will be deemed duly given when actually received, when sent by email, when sent by certified mail (return receipt requested) and deposited with postage prepaid in a post
office or branch post office regularly maintained by the United States Postal Service, when delivered by a nationally recognized express shipping company or upon receipt of a facsimile transmission confirmation. 

 

	4.3	Titles. 

 Titles are provided herein for convenience only and are not to serve as a basis for
interpretation or construction of this Agreement. 
  

	4.4	Conformity to Securities Laws. 

 Participant acknowledges that the Plan, the Grant Notice and
this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed amended as necessary to conform to Applicable Laws. 

 

	4.5	Successors and Assigns. 

 The Company may assign any of its rights under this Agreement to
single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in the Plan, this Agreement will be binding upon and inure to the benefit of
the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
  

	4.6	Limitations Applicable to Section 16 Persons. 

 Notwithstanding any other provision of the
Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement, the PRSUs and the Dividend Equivalents will be subject to any additional limitations set forth in any applicable
exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule. To the extent Applicable Laws
permit, this Agreement will be deemed amended as necessary to conform to such applicable exemptive rule. 

  
 41 

	4.7	Entire Agreement. 

 The Plan, the Grant Notice and this Agreement (including any exhibit hereto)
constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 

 

	4.8	Agreement Severable. 

 In the event that any provision of the Grant Notice or this Agreement is
held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 

 

	4.9	Limitation on Participant’s Rights. 

 Participation in the Plan confers no rights or
interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of
itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the PRSUs and Dividend Equivalents, and rights no greater
than the right to receive cash or the Shares as a general unsecured creditor with respect to the PRSUs and Dividend Equivalents, as and when settled pursuant to the terms of this Agreement. 

 

	4.10	Not a Contract of Employment. 

 Nothing in the Plan, the Grant Notice or this Agreement confers
upon Participant any right to continue in the employ or service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or
terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

 

	4.11	Counterparts. 

 The Grant Notice may be executed in one or more counterparts, including by way
of any electronic signature, subject to Applicable Laws, each of which will be deemed an original and all of which together will constitute one instrument.

 Exhibit A 

RESTRICTED SHARE UNIT AGREEMENT 

Capitalized terms not specifically defined in this Agreement have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the
Plan. 
  

	1.	GENERAL 

  

	1.1	Award of RSUs and Dividend Equivalents. 

  

	 	(a)	The Company has granted the RSUs to Participant effective as of the grant date set forth in the Grant Notice (the “Grant Date”). Each RSU represents the right to receive one Share or, at the option of
the Company, an amount of cash, in either case, as set forth in this Agreement. Participant will have no right to the distribution of any Shares or payment of any cash until the time (if ever) the RSUs have vested. 

 

	 	(b)	The Company hereby grants to Participant, with respect to each RSU, a Dividend Equivalent for ordinary cash dividends paid to substantially all holders of outstanding Shares with a record date after the Grant Date and
prior to the date the applicable RSU is settled, forfeited or otherwise expires. Each Dividend Equivalent entitles Participant to receive the equivalent value of any such ordinary cash dividends paid on a single Share. The Company will establish a
separate Dividend Equivalent bookkeeping account (a “Dividend Equivalent Account”) for each Dividend Equivalent and credit the Dividend Equivalent Account (without interest) on the applicable dividend payment date with the amount of
any such cash paid. 

  

	1.2	Incorporation of Terms of Plan. 

 The RSUs are subject to the terms and conditions set forth in
this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control. 

 

	1.3	Unsecured Promise.

represent an unsecured Company obligation payable only from the Company’s general assets. 
  

	2.	VESTING; FORFEITURE AND SETTLEMENT 

  

	2.1	Vesting; Forfeiture. 

 The RSUs will vest according to the vesting schedule in the Grant Notice
except that any fraction of an RSU that would otherwise be vested will be accumulated and will vest only when a whole RSU has accumulated. In the event of Participant’s Termination of Service for any reason, all unvested RSUs will immediately
and automatically be cancelled and forfeited, except as otherwise determined by the Administrator or provided in a binding written agreement between Participant and the Company. Dividend Equivalents (including any Dividend Equivalent Account
balance) will vest or be forfeited, as applicable, upon the vesting or forfeiture of the RSU with respect to which the Dividend Equivalent (including the Dividend Equivalent Account) relates. 

  
 45 

	2.2	Settlement. 

  

	 	(a)	RSUs and Dividend Equivalents (including any Dividend Equivalent Account balance) will be paid in Shares or cash at the Company’s option as soon as administratively practicable after the vesting of the applicable
RSU, but in no event more than sixty (60) days after the RSU’s vesting date. Notwithstanding the foregoing, to the extent permitted under Applicable Laws, the Company may delay any payment under this Agreement that the Company reasonably
determines would violate Applicable Laws until the earliest date the Company reasonably determines the making of the payment will not cause such a violation. 

  

	 	(b)	If an RSU is paid in cash, the amount of cash paid with respect to the RSU will equal the Fair Market Value of a Share on the day immediately preceding the payment date. If a Dividend Equivalent is paid in Shares, the
number of Shares paid with respect to the Dividend Equivalent will equal the quotient, rounded down to the nearest whole Share, of the Dividend Equivalent Account balance divided by the Fair Market Value of a Share on the day immediately preceding
the payment date.

Company or any of its agents. 
  

	3.2	Tax Withholding. 

  

	 	(a)	 On each vesting date, and on or before the time Participant receives a distribution of the shares underlying the
RSUs, and at any other time as reasonably requested by the Company in accordance with applicable tax laws (including, without limitation, in connection with the payment of any Dividend Equivalent), Participant hereby authorizes any required
withholding from the shares issuable to Participant and/or otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any parent or

or other method permitted by the Company); or (iii) withholding shares from the shares issued or otherwise issuable to Participant in connection with Participant’s RSUs with a fair market value (measured as of the date shares are issued to
Participant) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares so withheld will not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum
statutory withholding rates for federal, state, local and, if applicable, foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and, provided, further, that to the extent necessary to qualify for an
exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the prior approval of the Company’s Compensation Committee. 

 

	 	(b)	Participant hereby acknowledges and agrees to the following:

the Plan and this Agreement as a result of the shares vesting (or being issued, as applicable) and (B) all applicable fees and commissions due to, or required to be collected by, the Agent with respect thereto; and 

 

	 	(B)	To remit any remaining funds to Participant. 

  

	 	(ii)	Participant hereby authorizes the Company and the Agent to cooperate and communicate with one another to determine the number of shares that must be sold pursuant to this Section 3.2(b). 

 

	 	(iii)	 Participant understands that the Agent may effect sales as provided in this Section 3.2(b) in one or more

provided by in this Section 3.2(b) due to (A) a legal or contractual restriction applicable to Participant or the Agent, (B) a 

  
 47 

	 	
market disruption, or (C) rules governing order execution priority on the national exchange where the shares may be traded. In the event of the Agent’s inability to sell shares
underlying Participant’s RSUs, Participant will continue to be responsible for the timely payment to the Company of all Withholding Taxes and any other federal, state, local and foreign taxes that are required by Applicable Laws and regulations
to be withheld, including but not limited to those amounts specified in this Section 3.2(b). 

  

	 	(iv)	Participant acknowledges that regardless of any other term or condition of this Section 3.2(b), the Agent will not be liable to Participant for (A) special, indirect, punitive, exemplary, or consequential
damages, or incidental losses or damages of any kind, or (B) any failure to perform or for any delay in performance that results from a cause or circumstance that is beyond its reasonable control.

with respect to any tax withholding obligations that arise in connection with the RSUs or Dividend Equivalents. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in
connection with the awarding, vesting or payment of the RSUs or the Dividend Equivalents or the subsequent sale of Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure the RSUs or Dividend Equivalents to
reduce or eliminate Participant’s tax liability.

 In the event that any provision of the Grant Notice or this Agreement is
held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 

 

	4.9	Limitation on Participant’s Rights. 

 Participation in the Plan confers no rights or
interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of
itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the RSUs and Dividend Equivalents, and rights no greater than
the right to receive cash or the Shares as a general unsecured creditor with respect to the RSUs and Dividend Equivalents, as and when settled pursuant to the terms of this Agreement. 

 

	4.10	Not a Contract of Employment. 

 Nothing in the Plan, the Grant Notice or this Agreement confers
upon Participant any right to continue in the employ or service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or
terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

 

	4.11	Counterparts. 

 The Grant Notice may be executed in one or more counterparts, including by way
of any electronic signature, subject to Applicable Laws, each of which will be deemed an original and all of which together will constitute one instrument.
