The Committee has absolute discretion to make Awards under this Plan that are linked to the mandatory deferral of a Bonus and to make Awards that have no link to a Bonus. 2.3 Mandatory deferral of Bonus In respect of any Financial Year, the extent to which a Bonus will be mandatorily deferred (if at all) through the grant of an Award under this Plan, will be:

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 5 of 28 2.3.1 to the extent an Employee is required by the Policy to defer their Bonus, in accordance with the terms of the Policy; and 2.3.2 in all other cases, as determined by the Committee and communicated to the relevant Employee. 2.4 Grant of Awards Awards will be granted by the Company executing a deed. 2.5 Timing of grant Awards can only be granted within 42 days starting on any of the following: 2.5.1 the Business Day after the announcement of the Company’s results through a Regulatory Information Service for any period; 2.5.2 the Business Day after any general meeting of the Company; 2.5.3 any day on which the Company decides that exceptional circumstances exist which justify the grant of Awards (such as in connection with a recruitment); 2.5.4 any day on which changes to the legislation or regulations affecting the Plan are announced, effected or made; 2.5.5 if the Award is granted in lieu of some or all of a bonus, the date on which the bonus is or would otherwise have been payable; or 2.5.6 the lifting of Dealing Restrictions which prevented the granting of Awards during any period specified above. 2.6 Administrative errors If the Committee purports to grant an Award which is inconsistent with any of the provisions in this Plan, the Award will take effect only to the extent permissible under this Plan. 2.7 Issue of Award Certificate As soon as practicable after an Award has been made, the Committee will issue or will procure the issue of an Award Certificate to each Participant.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 6 of 29 2.8.8 if Malus and Clawback applies to the Award and where the Malus and Clawback provision are set out; 2.8.9 if the Award is subject to the Restrictive Covenants; 2.8.10 details of any Holding Period that applies to the Award; and 2.8.11 where the Committee requires it, that the Participant will enter into a Tax Election. 2.9 Awards to directors An Award that is to be granted to a director of the Company must not be a Long Term Incentive Scheme for the purposes of the Listing Rules of the UK Listing Authority. 2.10 Malus and Clawback Where an Award is granted subject to Malus and Clawback, if there is any discrepancy between the Malus and Clawback provisions and the Plan, the Malus and Clawback provisions will prevail. 2.11 No payment Participants are not required to pay for the grant of any Award. 2.12 Acceptance of Award The Committee may require a Participant to accept their Award by delivering a duly completed acceptance notice in a form and manner (which may be electronic), and by such date as, determined by the Committee, and to the extent the Participant does not do so their Award will lapse. 2.13 Liability for Taxation By participating in the Plan, a Participant agrees they are responsible for and will bear any liability for Taxation. 3. Phantom Awards 3.1 Grant of Phantom Awards The Committee may from time to time choose to grant an Award as a Phantom Award. A Phantom Award will not confer any right on the relevant Participant to receive Shares or any interest in Shares. 3.2 Application and interpretation of the Plan Where an Award is granted as a Phantom Award, the provisions of this Plan will be interpreted and applied to reflect the fact that Phantom Awards are granted in respect of notional Shares only and are satisfied in cash only. References to Conditional Awards will include Phantom Awards where relevant. 3.3 Holding Period If a Holding Period is to apply to a Phantom Award, the Committee will determine how the Holding Period will be operated and will communicate this to the Participant.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 7 of 29 4. Performance Conditions and other conditions 4.1 Application of Performance Conditions The Committee may determine that the Vesting of an Award will be conditional on the satisfaction of one or more Performance Conditions. Such determination may apply to Awards made to a particular Employee or category of Employees. 4.2 Application of other conditions The Vesting of Awards may be subject to other conditions set by the Committee, which may be different for different Employees. 4.3 Requirements of Performance Conditions and other conditions Any Performance Condition or other condition applicable to an Award must be objective and specified in the relevant Award Certificate. 4.4 Amendment or variation of Performance Conditions or other conditions The Committee may amend or vary a Performance Condition or other condition applicable to an Award where an event occurs which causes the Committee to reasonably consider that the Performance Condition or other condition is no longer appropriate. Any amended or varied Performance Condition or other condition will not be materially less difficult to satisfy than the original Performance Condition or other condition was intended to be at the Grant Date. Where a Performance Condition or other condition applicable to an Award is amended or varied in accordance with this rule the Award will then take effect subject to the Performance Condition or other condition as amended or varied. The Committee will notify any affected Participant as soon as practicable after any determination made under this rule. 4.5 Overarching discretion of the Committee Notwithstanding any other provision of this Plan, the Committee, acting reasonably and in good faith, may reduce (including to zero) the amount of an Award which would otherwise Vest if the formulaic outcome of any Performance Condition is, in the opinion of the Committee, not justified (including, but not limited to, on the basis of the wider underlying financial performance of the Group over the Performance Period). To the extent that an Award is reduced, the Awards will immediately lapse. 5. Individual limit for Executive Directors An executive director of the Company may only participate in the Plan up to the limits set out in the Policy (including in relation to recruitment, if applicable). If the Committee purports to confer participation in the Plan on terms which are inconsistent with these limits, participation will be deemed to take place only to the extent permissible under this rule. 6. Other terms applicable to Awards 6.1 No transfer A Participant may not transfer, assign, charge or otherwise dispose of an Award or any rights in respect of it. If they do, whether voluntarily or involuntarily, then it will immediately lapse. This rule does not apply to the transmission of an Award on the death of a Participant to their personal representatives.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 8 of 29 6.2 Bankruptcy A Participant’s Award will lapse where the Participant becomes bankrupt or enters into a compromise with their creditors generally. 6.3 Estimates or indications of performance If, prior to Vesting, there is or may be any interim estimate or indication of whether or to what extent a Performance Condition will be met, such interim estimate or indication will not create any right or expectation that limits: 6.3.1 the Committee’s discretion to determine whether, and to what extent, a Performance Condition or other condition applicable to an Award is satisfied; and 6.3.2 the ability of the Committee to make any adjustments to an Award, or the extent to which an Award will Vest, in in each case in accordance with the provisions of the Plan. 7. Dividend Equivalents The Committee may decide at any time prior to the transfer of the Shares to which a Conditional Award relates that Participants will receive an amount (in cash and/or additional Shares) equal in value to any dividends that would have been paid on those Shares by reference to dividend record dates falling between the Grant Date and the date on which the Award Vests. This amount may assume the reinvestment of dividends (on such basis as the Committee may determine) and may exclude or include special dividends and any such amount will be payable as soon as practicable after Vesting of the relevant Award. 8. Vesting of Awards – general rules 8.1 Determination of the Committee The Committee will, as soon as reasonably practicable after the end of the relevant Performance Period (or, where rules 11 (Leavers) or 12 (Company events) will apply prior to the end of the relevant Performance Period, at the relevant time pursuant to those rules), determine the extent to which any Performance Conditions and any other conditions applicable to an Award have been satisfied and, consequently, the extent to which that Award will Vest. Insofar as the Committee determines that any Performance Conditions or such other conditions applicable to the Award are not satisfied and are no longer capable of being satisfied, either in whole or part, the Award will immediately lapse in whole or part (as appropriate). 8.2 Vesting – rounding down If, due to the application of a Performance Condition or any term of the Award, an Award would otherwise Vest over a fraction of a Share, the number of Shares in respect of which the Award will Vest will be rounded down to the nearest whole number. 8.3 Timing of Vesting – general Subject to rules 8.4 (Timing of Vesting – Dealing Restrictions), 8.5 (Timing of Vesting – investigation), 11 (Leavers) and 12 (Company events), an Award will Vest on the later of: 8.3.1 where relevant, the date the Committee determines the extent to which any Performance Conditions and any other conditions applicable to that Award have been satisfied pursuant to rule 8.1 (Determination of the Committee); and

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 9 of 29 8.3.2 the relevant Vesting Date. 8.4 Timing of Vesting – Dealing Restrictions Where an Award would otherwise Vest at a time when Dealing Restrictions would prohibit: 8.4.1 the delivery, or procurement of the delivery, of Shares or cash (as appropriate) to the Participant; and/or 8.4.2 the Participant from selling Shares to discharge any liability for Taxation, where relevant, such Award will not Vest until all such Dealing Restrictions cease to apply. 8.5 Timing of Vesting – investigation Notwithstanding any other provision of this Plan, if an investigation commences or is ongoing regarding whether Malus and/or Clawback should be invoked in respect of a Participant then, unless otherwise determined by the Committee, any unvested Awards held by that Participant will not Vest, if at all, until after such investigation has been concluded. 8.6 Consequences of lapse Subject to rule 11.4, to the extent an Award lapses under the Plan, it may not Vest subsequently under any other provision of this Plan. 9. Satisfaction of Awards 9.1 Delivery – general Subject to the other provisions of this rule, where an Award Vests, as soon as reasonably practicable after such Vesting, the Committee will arrange for: 9.1.1 in respect of a Conditional Award, the delivery to the Participant of the number of Shares in respect of which the Award has Vested; or 9.1.2 in respect of a Phantom Award, the delivery of a cash sum equal to the aggregate Market Value of such number of notional Shares in respect of which the Award has Vested. 9.2 Delivery – investigation Notwithstanding any other provision of this Plan, if an investigation commences or is ongoing regarding whether Malus and/or Clawback should be invoked in respect of a Participant then, unless otherwise determined by the Committee, any Vested but as yet unsatisfied Awards held by that Participant will not be satisfied, if at all, until after such investigation has been concluded. 9.3 Delivery – nominee Shares may be delivered to a nominee on behalf of the Participant. 9.4 Delivery – Dealing Restrictions If the delivery, or the procurement of the delivery, of Shares or cash (as appropriate) would be prohibited by Dealing Restrictions, delivery will not occur until after such time as all such Dealing Restrictions cease to apply.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 10 of 29 9.5 Source of Shares Awards may be satisfied using Shares purchased in the market. No new Shares may be issued and no Shares may be transferred out of treasury for the purposes of the Plan. 9.6 Shareholder rights Where Shares are transferred on the Vesting of a Conditional Award, the Participant will be entitled to all rights attaching to the Shares by reference to a record date on or after the transfer date. 9.7 Alternative ways to satisfy Awards 9.7.1 The Committee may decide to satisfy an Award by paying a cash amount equal to the aggregate Market Value of the Shares in respect of which the Award has Vested. 9.7.2 The Committee may decide to satisfy an Award (or part of it) by reducing the number of Shares to which the Participant would otherwise be entitled under the Plan, with the reduction instead being paid as an equivalent amount in cash. 9.8 Withholding Any Member of the Group or the trustee of any employee benefit trust may withhold such amounts and make such arrangements as it considers necessary or desirable to meet any liability to pay or account for Taxation. The arrangements referred to in this rule may include deductions from any cash payment owed to the Participant and/or the sale of Shares acquired on Vesting of the Participant’s Award on behalf of the Participant and the retention of all or part of the sale proceeds to meet such liability. 10. Holding Period 10.1 Application of Holding Period The Committee may determine that a Holding Period will apply to an Award. Such determination may apply to Awards made to a particular Employee or category of Employees. 10.2 Nature of Holding Period During a Holding Period, an Award and the Shares subject to an Award and/or acquired by the Participant following Vesting of the Award, (or any interest in them) may not be transferred, assigned or otherwise disposed of by or on behalf of the Participant, save for: 10.2.1 a transfer to the Participant’s personal representative in the event of their death; 10.2.2 a transfer to a nominee on behalf of the Participant; 10.2.3 a sale in accordance with rule 9.8 (Withholding) or, with the prior agreement of the Company, to fund any liability for Taxation; 10.2.4 a transfer in accordance with any relevant Malus and Clawback provisions, or 10.2.5 a transfer to an Acquiring Company in connection with a company event (provided for in rule 12 (Company events). and any such purported action will be invalid and ineffective.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 11 of 29 10.3 Holding of Shares during the Holding Period Where a Holding Period applies to the Shares acquired on the Vesting of an Award, the Committee will determine that the Shares will be held during the Holding Period either by: 10.3.1 the Participant, provided they agree not to transfer, assign or otherwise dispose of the Shares (or any interest in them) during the Holding Period; or 10.3.2 a nominee on behalf of the Participant, provided that the Participant is subject to a restriction on transfer, assignment or other disposal of such Shares (or any interest in them) during the Holding Period. 10.4 Expiry of the Holding Period If the Shares are held by a nominee during the Holding Period, on or shortly following expiry of the Holding Period, the Shares will be capable of being transferred into the name of the Participant. 10.5 Proof of ownership A Participant must provide such proof of continued ownership as the Committee may at any time request. 11. Leavers 11.1 Leavers – before Vesting Subject to the remaining provisions of this rule, where a Participant ceases to be employed within the Group before their Award has Vested, their Award will lapse on the date they cease to be so employed. 11.2 Good leavers If a Participant ceases to be employed within the Group, after at least 6 months from the Grant Date (unless the Committee determines otherwise), due to: 11.2.1 injury, ill health or disability (in each case, evidenced to the satisfaction of the Committee); 11.2.2 death; 11.2.3 retirement with the agreement of the Committee; or 11.2.4 any other reason, determined at the discretion of the Committee, their Award will: 11.2.5 in the event of retirement (in accordance with rule 11.2.3): (i) Vest on the original Vesting Date unless the Committee determines otherwise; and (ii) only Vest to the extent prescribed in rule 11.3 (Good leavers – extent of Vesting). 11.2.6 in the event of death (in accordance with 11.2.2): (i) Vest on the date of death, or a later date determined by the Committee; and (ii) Vest in full, notwithstanding any Performance Conditions or other conditions applicable to the Award. 11.2.7 in the event of any of the other reasons set out in rule 11.2 (Good leavers):

In relation to any cash or Shares acquired pursuant to an Award prior to the relevant event, the Committee may determine that Malus and Clawback will no longer apply to the Award or will be varied in its application to the Award. 12.9 Restrictive Covenants Restrictive Covenants, applicable to an Award or Shares that have been or will be acquired following Vesting of an Award, will continue to apply following the date that Awards Vest under any provision in this rule 12 (Company events), unless the Committee determines otherwise. 12.10 Meaning of Committee For the purposes of this rule 12 (Company events) and rule 13 (Exchange of Awards), “Committee” means those people who were members of the Compensation Committee or such other committee of the Board immediately before the relevant event. 13. Exchange of Awards 13.1 When Awards may be exchanged Where an event as specified in rules 12.2 (Takeovers) 12.3 (Bound or entitled) or 12.4 (Scheme of arrangement) occurs and: 13.1.1 the Participant has agreed with the Acquiring Company that they will exchange their Award for a New Award; or 13.1.2 the Acquiring Company consents and substantially all the shareholders of the Company immediately before the relevant event has occurred will continue to have Control of the Company immediately thereafter, that Award (or, in the case of rule 13.1.2, all Awards) will not Vest under rules 12.2 (Takeovers), 12.3 (Bound or entitled) or 12.4 (Scheme of arrangement), as appropriate, but will be exchanged for New Awards. 13.2 Requirements for a New Award Where a Participant is granted a New Award in exchange for an existing Award, the New Award: 13.2.1 must confer a right relating to shares in the Acquiring Company or another body corporate determined by the Acquiring Company; 13.2.2 must be substantially equivalent to the Award;

No such third party has any rights under the UK Contracts (Rights of Third Parties) Act 1999 or any equivalent local legislation to enforce any term of this Plan. 17. Administration 17.1 Committee’s powers The Committee will administer the Plan. The Committee has authority to make rules and regulations for the administration of the Plan. The Committee may delegate all or any of its rights and powers under the Plan. 17.2 Provisions of the Plan If any provision of the Plan is held to be invalid, illegal or unenforceable for any reason by any court of competent jurisdiction, for the purposes of that jurisdiction: 17.2.1 such provision will be treated as severed; and 17.2.2 the remainder of the provisions of the Plan will continue in full force and effect as if the Plan had been established without the inclusion of the severed provision, unless the Committee determines otherwise.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 18 of 29 17.3 Committee’s decisions final and binding All determinations or decisions of the Committee are final and binding in all respects. If any question or dispute arises as to the interpretation of the Plan, any rules, regulations or procedures relating to the Plan and/or in relation to an Award or any other matter relating to the Plan, the decision of the Committee will be conclusive. 18. Changing the Plan and termination 18.1 Committee’s powers Except as described in the rest of this rule, the Committee may at any time change the Plan in any way. 18.2 Participant consent If the Committee proposes an amendment to the Plan which would be to the material disadvantage of Participants in respect of subsisting rights under the Plan, then: 18.2.1 the Committee must invite each so disadvantaged Participant to indicate whether or not they approve the amendment; and 18.2.2 such amendment will only take effect in respect of subsisting rights under the Plan if the majority of the Participants who make such an indication approve the amendment. 18.3 Notice The Committee may (but is not obliged to) give written notice of any changes made to the Plan to any Participant affected. 18.4 Termination of the Plan No Award may be granted after 12 June 2028 but the Committee may terminate the Plan at any earlier time.

The courts of England and Wales have non-exclusive jurisdiction in respect of disputes arising under or in connection with the Plan or any Award. 19.1.2 In relation to the Plan and any documents relating to or concerning it, the English language version of the documents will prevail, so that if there is any conflict between the terms or provisions of a document in English and the same document in another language, the document in English will take precedence.

References to the Plan, or to the rules, in the main rules of the Plan shall be interpreted to include this Schedule 1 in relation to US Taxpayers. 1 Application This Schedule 1 shall apply to all employees and Participants who are US Taxpayers. If a Participant becomes a US Taxpayer after grant of an Award under the Plan, then it will immediately be amended in a manner consistent with this Schedule 1. References in this Schedule 1 to Awards granted to US Taxpayers shall include Awards held by a Participant who becomes a US Taxpayer after an Award is granted. 2 Definitions 2.1 The definitions in the Plan shall have the same meaning in this Schedule 1 unless expressly stated otherwise. 2.2 For the purposes of this Schedule 1 the following additional definitions will also apply: “Award Short-Term Deferral Period” means the period starting on the date that a Conditional Award (or portion thereof) first is no longer subject to a “substantial risk of forfeiture” for the purposes of Section 409A and ending on the 15th day of the third month following the end of the Taxable Year in which such Conditional Award first is no longer subject to the substantial risk of forfeiture; “Code” means the US Internal Revenue Code of 1986, as amended. “Option Short-Term Deferral Period” means the period starting on the date that an Option (or portion thereof) first is no longer subject to a “substantial risk of forfeiture” for the purposes of Section 409A and ending on the immediately following 31 December; “Section 409A” means Section 409A of the Code and the Treasury Regulations promulgated and other official guidance issued thereunder, collectively; “Taxable Year” means the calendar year, or, if later, the end of the taxable year of the Member of the Group that employs the US Taxpayer, in which the Conditional Award first is no longer subject to a substantial risk of forfeiture for the purposes of Section 409A; “Treasury Regulations” means the regulations, including proposed or temporary regulations, promulgated under the Code. “US” means the United States of America; and “US Taxpayer” means an employee or Participant who is subject to US federal income taxation on the date on which an Award is granted, is expected to become subject to US federal income taxation following that date or does become subject to US federal income taxation following that date but before the date on which any part of the Award Vests. 3 Consequences of Vesting for Conditional Awards 3.1 Subject to paragraph 3.2 below, but notwithstanding any other provision of the Plan (including, but not limited to, rule 4.3 (Timing of Vesting – investigation), rule 4.5

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 20 of 29 (Consequences of Vesting for Conditional Awards), rule 4.7 (Delivery – investigation) and rule 5.3 (Exceptions to the general rule)), the satisfaction of a Conditional Award (or portion thereof) granted to a US Taxpayer, whether in Shares or in cash, shall be made no later than the end of the Award Short-Term Deferral Period. 3.2 If a Conditional Award (or portion thereof) granted to a US Taxpayer has not been satisfied by the end of the Award Short-Term Deferral Period because such satisfaction would have violated applicable law, then to the extent permissible under Section 1.409A-1(b)(4)(ii) of the proposed Treasury Regulations, the satisfaction may be delayed so long as the Conditional Award is then satisfied at the earliest date at which it is reasonably anticipated that such law no longer prevents the satisfaction. 3.3 If, as a result of paragraph 3.1 or 3.2 of this Schedule 1, a Conditional Award (or portion thereof) granted to a US Taxpayer has to be satisfied before the Conditional Award (or portion thereof) Vests then, subject to rule 4.10 (responsibility for tax) and unless the Compensation Committee provides otherwise, the US Taxpayer may not transfer, assign, charge or create any other security interest over or otherwise dispose of the Shares or cash received from the settlement of the Conditional Award (or portion thereof) or any rights in respect thereof until the Conditional Award (or portion thereof) Vests. If after the end of the Award Short-Term Deferral Period, the Conditional Award (or portion thereof) does not Vest, then the Shares or cash received from the settlement of the Conditional Award (or portion thereof) which did not Vest will be immediately forfeited and the Participant must immediately pay the cash or transfer their interest in the Shares, for no consideration or nominal consideration, to any person (which may include the Company, where permitted) specified by the Compensation Committee.. 3.4 For the avoidance of doubt, nothing in this paragraph 3 (Consequences of Vesting for Conditional Awards) shall limit or impair any Holding Requirement applicable to the Shares or cash received from the satisfaction of a Conditional Award. 3.5 If a Conditional Award (or portion thereof) granted to a US Taxpayer includes a right to a Dividend Equivalent under rule 2.8 (Dividend Equivalents), payment of the Dividend Equivalent (in cash or Shares) must be made no later than the end of the Award Short-Term Deferral Period applicable to such Dividend Equivalent, or, if later, the end of the extended period provided by paragraph 3.2 of this Schedule 1. 4 Consequences of Vesting for Options 4.1 Subject to paragraph 4.2 below, but notwithstanding any other provision of the Plan (including, but not limited to, rule 4.6 (Consequences of Vesting for Options), rule 5.3 (Exceptions to the general rule) and rule (Exercise period for Options)), an Option granted to a US Taxpayer must be exercised no later than the end of the applicable Option Short- Term Deferral Period. 4.2 If an Option (or portion thereof) granted to a US Taxpayer has not been exercised by the end of the Option Short-Term Deferral Period because such exercise would have violated applicable law, then to the extent permissible under Section 1.409A-1(b)(4)(ii) of the proposed Treasury Regulations, the Option may be exercised later, so long as it is exercised at the earliest date at which it is reasonably anticipated that such law no longer prevents the exercise. 4.3 If, as a result of paragraph 4.1 or 4.2 of this Schedule 1, an Option (or portion thereof) granted to a US Taxpayer has to be exercised before the Option (or portion thereof) Vests,

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 21 of 29 then subject to rule 4.10 (responsibility for tax) and unless the Compensation Committee provides otherwise, the US Taxpayer may not transfer, assign, charge or create any other security interest over or otherwise dispose of the Shares or cash received from the exercise of the Option (or portion thereof) or any rights in respect thereof until the Option (or portion thereof) Vests. If after the end of the Option Short-Term Deferral Period, the Option (or portion thereof) does not Vest, then the Shares or cash received from the exercise of the Option (or portion thereof) which did not Vest will be immediately forfeited and the Participant must immediately pay the cash or transfer their interest in the Shares, for no consideration or nominal consideration, to any person (which may include the Company, where permitted) specified by the Compensation Committee. 4.4 For the avoidance of doubt, nothing in this paragraph 4 (Consequences of Vesting for Options) shall limit or impair any Holding Requirement applicable to the Shares or cash received from the exercise of an Option. 4.5 If an Option (or portion thereof) granted to a US Taxpayer includes a right to a Dividend Equivalent under rule 2.8 (Dividend Equivalents), payment of the Dividend Equivalent (in cash or Shares) must be made no later than the end of the Option Short-Term Deferral Period applicable to such Dividend Equivalent 5 Changes to conditions 5.1 Other than to waive it, a Performance Condition or other condition applicable to an outstanding Award granted to a US Taxpayer may not be amended pursuant to rule 8.1 (Compensation Committee’s right to change the Plan or Awards), or any other provision of the Plan, if and to the extent that the amendment of the condition would result in the earlier ending of the applicable Award Short-Term Deferral Period or Option Short-Term Deferral Period. 5.2 An Award granted to a US Taxpayer may not be amended pursuant to rule 8.1 (Compensation Committee’s right to change the Plan or Awards), or any other provision of the Plan, if and to the extent that the amendment of the condition would result in violation of Section 409A. 6 Exchange of Awards Where there is to be an exchange of a US Taxpayer’s Award pursuant to rule 6.4 (Exchanging Awards rather than early Vesting) and rule 6.5 (What happens when Awards are exchanged), the Compensation Committee shall attempt to structure the terms of the exchange and the new award such that neither the exchange nor the new award violate Section 409A. 7 Interpretation and administrative intent 7.1 Awards granted, and Dividend Equivalents payable, to US Taxpayers are intended to be exempt from the requirements of Section 409A under the short-term deferral exception described in Section 1.409A-1(b)(4) of the US Treasury Regulations, and the Plan and this Schedule 1 shall be interpreted and administered consistent with such intention. 7.2 For the avoidance of doubt, any delay in the Vesting of an Award pursuant to rule 4.3 (Timing of Vesting – investigation), or the fact that a Holding Requirement pursuant to rule 2.4.7 or Schedule 3 (Holding Requirement), or clawback provisions pursuant to rule 2.11 (Malus and Clawback) or rule 7 (Restrictive Covenants) or Schedule 2 (Restrictive Covenants) may be

No Member of the Group shall have any obligation to indemnify or otherwise hold the US Taxpayer harmless from any or all of such taxes, penalty or interest.

This Schedule 2 does not amend, add or otherwise alter the Plan as it applies to other Awards than the Qualified Awards. References to rules are deemed references to the main rules of the Plan.

Qualified Awards 2.1 Grant of Awards The rules of the Plan, the terms of this Schedule 2 and the terms and conditions applicable to Qualified Awards shall be interpreted and, where necessary, deemed to be modified in order to satisfy the relevant provisions to qualify for the French specific income tax and social security treatment. 2.2 No liability No Member of the Group shall be liable for any adverse consequence, whether legal, tax or otherwise, if and to the extent the Qualified Awards do not qualify for such specific French income tax and social security treatment.

Notwithstanding the foregoing, should the Vesting Date be between 1 and 2 years from the Date of Grant, the Participant would then be required to hold the Shares for a period of no less than 1 year. 12. Clawback The reduction of the Participant’s salary as a method chosen by the Committee to recover the any amount under any relevant Malus and Clawback provisions from the Participant shall be limited to the frame set forth by French laws, which depends on the Participant’s personal situation. 13. Data Protection Pursuant to French laws, when becoming Participants, the Eligible French Employees have a right to access and amend personal data they provide to the Company and/or the Member of the Group in the context of the Plan.

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 26 of 29 Schedule 3: Restrictive Covenants This Schedule 3 (Restrictive Covenants) sets out the Restrictive Covenants that will apply to a Participant if specified to do so in the Participant’s Award Certificate. By participating in the Plan, a Participant may profit from and participate in the equity value of the Company. The purpose of this Schedule 3 (Restrictive Covenants) is to protect the legitimate business interests of the Company and the Group. 1. Covenants By participating in the Plan, a Participant undertakes with the Company, on behalf of itself and as agent for each Relevant Group Company, that the Participant will not in any Relevant Capacity at any time during the Restricted Period: 1.1 within or in relation to the Restricted Territory take any steps preparatory to or be directly or indirectly engaged, employed, interested or concerned in: (i) any Competing Business; and/or (ii) any Target Business Entity; or 1.2 within or in relation to the Restricted Territory acquire a substantial or controlling interest directly or by or through any nominee or nominees in any Competing Business, Target Business Entity or in any Person owning or controlling a Competing Business or Target Business Entity; or 1.3 solicit or attempt to solicit, canvass, interfere with or entice away from the Company or any Relevant Group Company the custom or any prospective custom of any Client or any Prospect with a view to providing to that Client or Prospect any products or services which are the same as or materially similar to any Restricted Business in competition with the Company or any Relevant Group Company; or 1.4 provide or agree to provide any products or services which are the same as or materially similar to any Restricted Business to any Client or any Prospect in competition with the Company or any Relevant Group Company; or 1.5 solicit, entice or encourage or attempt to solicit, entice or encourage any Key Individual to leave the employment of the Company or any Relevant Group Company (whether or not such person would commit any breach of their contract of employment by doing so); or 1.6 employ, engage, appoint, enter into partnership or association with or in any way cause to be employed, engaged or appointed any Key Individual in relation to any Competing Business or any Person which is or is proposed to be directly or indirectly owned by or controlling any Competing Business; or 1.7 provide or agree to provide any products or services which are the same as or materially similar to any Restricted Business in respect of any Competitor Account; or 1.8 be employed or engaged by any Client or Prospect if as a result the Client or Prospect will cease to use or materially reduce its usage of the products or services of the Company or any Relevant Group

WPP plc – Rules – The WPP plc Stock Plan 2018 Page 27 of 29 Company or, in the case of a Prospect, will not use the products or services of the Company or any Relevant Group Company or use them to a materially lesser extent; or 1.9 solicit or try to solicit or place orders for the supply of products or services from any Supplier if as a result the Supplier will cease supplying, materially reduce its supply or vary detrimentally the terms on which it supplies products or services to the Company or any Relevant Group Company; or 1.10 encourage, assist or procure any Person to do anything which if done by that Participant would be a breach of paragraphs 1.1 to 1.9 of this Schedule 3 (Restrictive Covenants) (or any of them). 2. Social Media Connecting or reconnecting to Clients, Suppliers or Prospects using Social Media during the Restricted Period may amount to a breach of paragraphs 1.1 to 1.10 of this Schedule 3 (Restrictive Covenants). 3. Reasonable and Severable By participating in the Plan, a Participant agrees that the restrictions (whether taken individually or as a whole) in paragraph 1 of this Schedule 3 (Restrictive Covenants) are reasonable, having regard to the legitimate protectable interests of the Company and each Relevant Group Company, and that each such restriction is intended to be separate and severable. In the event that any restriction is held to be void but would be valid if part of its wording was deleted, that restriction will apply with whatever deletions are necessary to make it valid and effective. 4. Equitable Relief By participating in the Plan, a Participant agrees that: 4.1 damages shall be an inadequate remedy in the event of a breach by that Participant of any of the restrictions contained in paragraph 1 of this Schedule 3 (Restrictive Covenants) and that any such breach by that Participant or on that Participant’s behalf will cause the Company and any Relevant Group Company great and irreparable injury and damage; and 4.2 the Company and/or any Relevant Group Company will therefore be entitled, without waiving any additional rights or remedies otherwise available to them at law or in equity or by statute, to injunctive and other equitable relief in the event of a breach or intended or threatened breach by that Participant, or on that Participant’s behalf, of any of the restrictions contained in paragraph 1 of this Schedule 3 (Restrictive Covenants). 5. Conflict If there is any conflict between a paragraph in this Schedule 3 (Restrictive Covenants) and a rule of the Plan, or the terms of a Participant’s employment contract, the paragraph in this Schedule 3 (Restrictive Covenants) will take precedence. 6.
