4.Vesting; Forfeiture. Any Performance Stock Units that become Earned PSUs will vest according to the vesting schedule in the Grant Notice and Annex 1 hereto except that any fraction of an Earned PSU that would otherwise be vested will be accumulated and will vest only when a whole Earned PSU has accumulated. In the event of your termination of Continuous Service for any reason, all unvested Performance Stock Units will immediately and automatically be cancelled and forfeited, except as otherwise determined by the Plan Administrator or provided in any Written Arrangement.

a.Regardless of any action taken by the Company or, if different, the Affiliate to which you provide Continuous Service (the “Service Recipient”) with respect to any income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax‑related items associated with the grant or vesting of the PSU Award or sale of the underlying Class A Common Stock or other tax-related items related to your participation in the Plan and legally applicable or deemed applicable to you (the “Tax Liability”), you hereby acknowledge and agree that the Tax Liability is your ultimate responsibility and may exceed the amount, if any, actually withheld by the Company or the Service Recipient. You further

acknowledge that the Company and the Service Recipient (i) make no representations or undertakings regarding any Tax Liability in connection with any aspect of this PSU Award, including, but not limited to, the grant or vesting of the PSU Award, the issuance of Class A Common Stock pursuant to such vesting, the subsequent sale of shares of Class A Common Stock, and the payment of any dividends on the shares; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PSU Award to reduce or eliminate your Tax Liability or achieve a particular tax result. Further, if you are subject to Tax Liability in more than one jurisdiction, you acknowledge that the Company and/or the Service Recipient (or former service recipient, as applicable) may be required to withhold or account for Tax Liability in more than one jurisdiction.

b.Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or the Service Recipient to satisfy all Tax Liability. As further provided in Section 8 of the Plan, you hereby authorize the Company and any applicable Service Recipient to satisfy any applicable withholding obligations with regard to the Tax Liability by one or a combination of the following methods, as chosen by the Company in its sole discretion: (i) causing you to pay any portion of the Tax Liability in cash or cash equivalent in a form acceptable to the Company and/or the Service Recipient; (ii) withholding from any compensation otherwise payable to you by the Company or the Service Recipient; (iii) withholding shares of Class A Common Stock from the shares of Class A Common Stock issued or otherwise issuable to you in connection with the Award; provided, however, 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 express prior approval of the Board or the Company’s Compensation Committee; (iv) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”), pursuant to this authorization and without further consent, whereby you irrevocably elect to sell a portion of the shares of Class A Common Stock to be delivered in connection with your Performance Stock Units to satisfy the Tax Liability and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Tax Liability directly to the Company or the Service Recipient; and/or (v) any other method determined by the Company to be in compliance with Applicable Law. Furthermore, you agree to pay or reimburse the Company or the Service Recipient any amount the Company or the Service Recipient may be required to withhold, collect or pay as a result of your participation in the Plan or that cannot be satisfied by the means previously described. In the event it is determined that the amount of the Tax Liability was greater than the amount withheld by the Company and/or the Service Recipient (as applicable), you agree to indemnify and hold the Company and/or the Service Recipient (as applicable) harmless from any failure by the Company or the applicable Service Recipient to withhold the proper amount.

Each issuance date determined by this paragraph is referred to as an “Original Issuance Date.”

i. the Original Issuance Date does not occur (1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to sell shares of Class A Common Stock on an established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into in compliance with the Company’s policies (a “10b5-1 Arrangement”)), and

ii. either (1) a Tax Liability withholding obligation does not apply, or (2) the Company decides, prior to the Original Issuance Date, (A) not to satisfy the Tax Liability withholding obligation by withholding shares of Class A Common Stock from the shares otherwise due, on the Original Issuance Date, to you under this Award, and (B) not to permit you to enter into a “same day sale” commitment with a broker-dealer (including but not limited to a commitment under a 10b5-1 Arrangement) and (C) not to permit you to pay your Tax Liability in cash, then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on such Original Issuance Date and will instead be delivered on the first business day when you are not prohibited from selling shares of the Class A Common Stock in the open public market, but, if you are subject to taxation in the United States, in no event later than December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that complies with U.S. Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the shares of Class A Common Stock under this Award are no longer subject to a “substantial risk of forfeiture” within the meaning of U.S. Treasury Regulations Section 1.409A-1(d).

In addition and notwithstanding the foregoing, no shares of Class A Common Stock issuable to you under this Section 6 as a result of the vesting of one or more Performance Stock Units will be delivered to you until after you have complied with any notification and waiting period requirements under the Hart-Scott-Rodino (“HSR”) Act in connection with the issuance of such shares (any such filings and/or waiting period required pursuant to HSR, the “HSR Requirements”). If the HSR Requirements apply to the issuance of any shares of Class A Common Stock issuable to you under this Section 6 upon vesting of one or more Performance Stock Units, such shares of Class A Common Stock will not be issued at such time set forth above and will instead be issued on the first business day on or following the date when all such HSR Requirements are satisfied and when you are permitted to sell shares of Class A Common Stock on an established stock exchange or stock market, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities. Notwithstanding the foregoing, the issuance date for any shares of Class A Common Stock delayed under this Section 6 shall in no event be later than December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), unless a later issuance date is permitted without incurring adverse tax consequences under Section 409A of the Code or other applicable law.

Based on the foregoing, you expressly recognize that the Plan and the benefits that you may derive from participation in the Plan do not establish any rights between you and the Service Recipient and do not form part of the service conditions and/or benefits provided by the Service Recipient, and any modification of the Plan or its termination shall not constitute a change or impairment of the terms and conditions of your service relationship with Service Recipient.

You further understand that your participation in the Plan is as a result of a unilateral and discretionary decision of the Company; therefore, the Company reserves the absolute right to amend and/or discontinue your participation in the Plan at any time without any liability to you.

Finally, you hereby declare that you do not reserve any action or right to bring any claim against the Company for any compensation or damages regarding any provision of the Plan or the benefits derived under the Plan, and you therefore grant a full and broad release to the Company and its Affiliates, branches, representation offices, shareholders, officers, employees, agents or legal representatives with respect to any claim that may arise.

Nature of Grant. The following supplements Section 7 of the PSU Award Agreement:

By accepting your PSU Award, you consent to participation in the Plan and acknowledge that you have received a copy of the Plan.

You understand that the Company has unilaterally, gratuitously and in its sole discretion decided to grant PSU Awards to individuals providing service to the Company or an Affiliate. The decision is limited and entered into based upon the express assumption and condition that (i) any grant will not bind the Company, other than as expressly set forth in the PSU Award Agreement (i.e., it is not to be considered an acquired right or a more beneficial condition to be repeated in the future); (ii) the PSU Awards are granted on the assumption and condition that the PSU Awards and any shares of Class A Common Stock that may be acquired upon settlement of the PSU Awards are not part of any employment contract and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation), or any other right whatsoever; and (iii) the PSU Awards will cease vesting on the date of termination of Continuous Service (as detailed in the following paragraph). In addition, you understand that this grant would not be made to you but for the assumptions and conditions referred to herein; thus, you acknowledge and freely accept that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then the grant of the PSU Award shall be null and void.

The vesting of the PSU Award is expressly conditioned on your Continuous Service such that, upon termination of Continuous Service for any reason whatsoever, the PSU Award will cease vesting immediately on the date of such

termination. This will be the case even if you are considered to be unfairly dismissed without good cause. For clarification purposes, vesting will immediately cease upon termination of Continuous Service, such as in the case of: resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without good cause (i.e., subject to a “despido improcedente”), material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, or under Article 10.3 of Royal Decree 1382/1985.

You acknowledge that you have read and specifically accept the vesting schedule set forth in the Platform and the conditions referred to in Section 7 of the PSU Award Agreement.

Securities Law Information. The grant of the PSU Award does not qualify under Spanish regulations as a security. No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the grant of the PSU Award. The PSU Award Agreement has not been nor will it be registered with the Comisión Nacional del Mercado de Valores and does not constitute a public offering prospectus.

Foreign Asset / Account Reporting Information. To the extent you hold shares of Class A Common Stock or have bank accounts outside of Spain with a value in excess of EUR 50,000 (for each type of asset category) as of December 31, you will be required to report information on such assets on your tax return Form 720 for such year. After such shares of Class A Common Stock or accounts are initially reported, the reporting obligation will apply for subsequent years only if the value of any previously reported shares of Class A Common Stock or accounts increases by more than EUR 20,000 (for each type of asset category) as of each subsequent December 31 or if you sell shares of Class A Common Stock or cancel bank accounts that were previously reported. You should consult with your personal tax advisor for further information regarding your foreign asset reporting obligations.

Exchange Control Information. You are required to electronically declare to the Bank of Spain any security accounts (including brokerage accounts held abroad), as well as the securities (including shares of Class A Common Stock acquired under the Plan) held in such accounts if the value of the transactions for all such accounts during the prior year or the balances of such accounts as of December 31 of the prior year exceeds EUR 1 million. Different thresholds and deadlines to file this declaration apply. However, if neither such transactions during the immediately preceding year nor the balances / positions as of December 31 exceed EUR 1 million, no such declaration must be filed unless expressly required by the Bank of Spain. If any of such thresholds were exceeded during the current year, you may be required to file the relevant declaration corresponding to the prior year; however, a summarized form of declaration may be available. You should consult your personal tax or legal advisor for further information regarding your exchange control reporting obligations.

Responsibility for Taxes. The following supplements Section 5 of the PSU Award Agreement:

Without limitation to Section 5 of the PSU Award Agreement, by accepting your PSU Award, you authorize the Company to collect any Tax-Related Items from you by withholding shares of Class A Common Stock from the shares of Class A Common Stock issued or otherwise issuable to you in connection with the Award or selling a portion of the shares of Class A Common Stock to be delivered in connection with your Performance Stock Units, regardless of whether the Company and/or the Service Recipient have an obligation to withhold such Tax-Related Items.

ii.to permit the Company to sell at the best price which it can reasonably obtain such number of shares of Class A Common Stock allocated or allotted to you following vesting as will provide the Company with an amount equal to the UK Tax Liability; and to permit the Company to withhold an amount not exceeding the UK Tax Liability from any payment made to you (including, but not limited to salary); and

iii.if so required by the Company, and, to the extent permitted by law, to enter into a joint election or other arrangements under which the liability for all or part of such employer’s national insurance contributions liability is transferred to you; and
