Due to the Executive's position the Executive shall be named on the Company's list of persons with access to inside information relating to the Company which may be made available to relevant authorities. 6.

Hours of Work 7.1 The Executive shall work such hours as are required for the proper and efficient performance of their duties including the Company’s normal business hours which are 9am until 5:30pm from Monday to Friday.

5 4135-1945-7548, v. 3 7.2 The Executive agrees that the limit on weekly working time contained in Regulation 4 of The Working Time Regulations 1998 does not apply because Regulation 20 applies to the Executive. 8. Salary 8.1 The Executive shall be paid a basic salary of £491,600 per annum subject to deductions required by law. The Executive’s salary shall accrue from day to day, shall be payable in equal monthly instalments in arrears on or about the last Friday of each month and shall include any directors’ fees. 8.2 The salary paid to the Executive may be reviewed annually. The Company is under no obligation to award an increase following a salary review. 8.3 The Company may deduct from the salary or any other sums payable to the Executive any money owed to any Group Company by the Executive.

Expenses The Company shall reimburse any expenses wholly, exclusively and necessarily incurred by the Executive in the proper performance of the Executive’s duties under this Agreement subject always to the rules and policies of the Company from time to time and subject to the Executive providing receipts or other evidence of payment as the Company may require. 10. Annual Bonus 10.1 The Executive shall be eligible to earn an annual incentive bonus, with a target bonus amount of 60% of the Executive’s basic salary (and the ability to earn up to 100% of the Executive’s basic salary in certain circumstances as determined by the Compensation and Leadership Development Committee of the Board), subject to such terms and with such individual, team or corporate targets as the Board may communicate from time to time. The Board shall be entitled to determine whether such targets have been met and where such targets have been met in full or part shall have a discretion to determine whether to make payments and, if so, in what amount and when. 10.2 The Board may suspend, alter or discontinue any bonus payment(s) or any bonus plan and its eligibility requirements at any time (whether generally or in relation to the Executive only) at its absolute discretion. If the Executive receives any bonus payment the Company is not obliged to make any further bonus payments and any bonus payment will not become part of the Executive's contractual remuneration or fixed salary. 10.3 The Executive will not be entitled to receive any bonus (or pro rata portion of it) if: 10.3.1 he has resigned; or 10.3.2 the Company has dismissed him, or would have been entitled to dismiss him, summarily pursuant to clause 21, on or prior to the date when the bonus would otherwise have been payable. Subject to clause 10.4 and clause 20.1, if the Executive is terminated by the Company on notice in circumstances which do not warrant summary dismissal, he will remain eligible

6 4135-1945-7548, v. 3 for a target bonus in respect of the year in which the employment terminates. 10.4 The Executive shall not be eligible to be considered for any bonus nor shall any bonus be paid if the Executive is subject to any disciplinary action or investigation at the date any bonus is being considered and/or at the bonus payment date (as applicable) although the

7 4135-1945-7548, v. 3 Company may reconsider the matter upon the conclusion of the disciplinary action or investigation in question. 11. Allowances 11.1 The Company will provide, at its sole discretion, assistance to the Executive in dealing with certain US and UK tax compliance matters in connection with Executive’s relocation to the UK through the provision of a tax advisor, who has agreed to provide the specific scope of services for £7,500 plus VAT and disbursements (the “Scope of Work”). For the avoidance of doubt, the Company shall not be obliged to pay for any tax assistance beyond this Scope of Work, nor to provide any assistance with any tax implications of non-Company income beyond this Scope of Work. 11.2 The Company will pay the fees for a visa for the Executive’s spouse in connection with Executive’s relocation to the UK. 11.3 If the provision of tax assistance, as outlined in clause 11.1, and payment of visa fees, as outlined in clause 11.2, creates any additional tax liabilities for the Executive, he will be required to pay the related taxes personally. 12. Pensions 12.1 The Company intends to comply with the employer pension duties in respect of the Executive in accordance with Part 1 of the Pensions Act 2008. Unless the Executive opts out, the Company will make a pension contribution equivalent to the level as is available to the general workforce (which is currently set at 3% of basic salary each month during employment). In the event the contribution level is increased for the general workforce, Executive’s contribution level will be increased to match the same; however and notwithstanding anything to the contrary, Executive’s contribution level will not exceed 5%. Any pension contribution or cash supplement amount will not be considered part of the Executive’s basic salary. The Executive may be required to periodically renew any opt out. 12.2 The Executive’s participation in the Company’s pension arrangements is subject to the rules of the relevant scheme and the statutory requirement as each are varied from time to time. In particular the Company reserves the right to change the scheme provider, the funds available, the charging structure and the default fund from time to time. 13. Benefit Plans 13.1 The Executive shall, during employment, be eligible to participate in the following benefit plans operated by the Company: 13.1.1 health insurance for the Executive; 13.1.2 life assurance; 13.1.3 permanent insurance cover. 13.2 The Executive’s participation in the benefit plans referred to in this clause are subject to: 13.2.1 the terms of that benefit plan, as amended from time to time; 13.2.2 the rules or the insurance policy of the relevant benefit provider, as amended from time to time; and 13.2.3 the Executive satisfying the normal underwriting requirements of the relevant

8 4135-1945-7548, v. 3 benefits provider (which may involve a medical and/or a medical questionnaire) and the premium being at a rate which the Company considers reasonable. 13.3 The Company’s obligation under this clause is limited to paying premiums to the relevant benefits provider. If the benefit provider refuses to accept a claim under the relevant benefit plan the Company shall have no obligation or responsibility to challenge that decision or to compensate the Executive. 13.4 The Company reserves the right to discontinue, vary or amend each benefit plan (including the level of cover) at any time on reasonable notice to the Executive. 14. Holidays 14.1 The Executive shall be entitled to 25 days' paid holiday in each holiday year together with the usual public holidays in England to be taken at times convenient to the Company and authorised in advance. In addition to this, the Executive shall be entitled to one day’s paid annual leave to be taken on or around their birthday. Finally, the Executive may be entitled to additional paid leave, based on service, as per the Holiday Policy (UK) available from the Board. 14.2 The Company's holiday year runs between 1 January and 31 December. If the Executive’s employment commences or terminates part way through a holiday year, the Executive's entitlement during that holiday year shall be calculated on a pro rata basis rounded up to the nearest whole day. 14.3 The Executive shall have no entitlement to any payment in lieu of accrued but untaken holiday except on Termination. The amount of such payment in lieu shall be 1/260th of the Executive's salary for each untaken day of entitlement. 14.4 If on Termination the Executive has taken in excess of their accrued holiday entitlement, the Company shall be entitled to recover from the Executive by way of deduction from any payments due to the Executive or otherwise, one day's pay for each excess day calculated at 1/260th of the Executive’s salary. 14.5 If either party has served notice to terminate the employment, the Company may require the Executive to take any accrued but unused holiday entitlement during the notice period. Any accrued but unused holiday entitlement shall be deemed to be taken during any period of Garden Leave. 15. Sickness 15.1 The Company may in its absolute discretion pay the Executive an amount equal to the Executive’s normal basic pay (“Company Sick Pay”) for the first 20 working days of sickness absence in any rolling 12 month period, subject to such conditions as set out in the Sick Leave Policy (UK) and/or as the Board may specify. Company Sick Pay will include any entitlement to statutory sick pay or any benefits provided by virtue of any permanent health insurance scheme. Company Sick Pay is also subject to the Executive’s compliance with this Agreement and will not be paid in respect of any period of illness that commences during the first 6 months of the Executive’s employment or whilst the Company is addressing performance or disciplinary issues. 15.2 The Executive must comply with the Company’s sickness absence notification procedures as set out in the Sick Leave Policy (UK). Any period of absence of up to seven calendar days may be self-certified and any period of absence of more than five days must be supported by doctor’s certificate.

9 4135-1945-7548, v. 3 15.3 The Executive consents to undergo a medical examination by a doctor nominated by the Company at the Company’s request and expense. 15.4 The rights of the Company to terminate the Executive’s employment under the terms of this Agreement apply even when such termination would or might cause the Executive to forfeit any entitlement to sick pay, permanent health insurance or other benefits. 16. Outside Activities and Interests 16.1 The Executive shall not during the employment except as a representative of the Company or with the Board’s prior written consent (whether directly or indirectly, paid or unpaid) be employed, engaged, concerned or interested in any other actual or prospective business, organisation, occupation or profession. Any such permission granted by the Board or the

10 4135-1945-7548, v. 3 Company prior to the date of this Agreement shall continue to apply during the term of this Agreement. 16.2 Nothing in this Agreement shall prevent the Executive from holding an investment by way of shares or other securities to in any entity listed or dealt on a recognised stock exchange (a “Permitted Investment”) provided always that during the term of the employment: (i) the Permitted Investment shall not constitute more than 3% of the issued share capital of the entity concerned, (ii) the Executive makes full disclosure of such Permitted Investments and any actual or apparent conflicts of interest resulting therefrom, so that the Company can make appropriate determinations on the propriety of any investment; and (iii) the Executive complies with the Quoted Company Requirements. 17. Confidential Information 17.1 Without prejudice to the Executive’s common law and fiduciary duties, the Executive shall not during employment or at any time after Termination and whether for their own benefit or for the benefit of any third party: 17.1.1 use any Confidential Information; or 17.1.2 disclose any Confidential Information to any person, company or other organisation whatsoever, except in the proper course of their duties, as required by law or as authorised by the Board in writing. 17.2 The Executive shall be responsible for protecting the confidentiality of the Confidential Information and shall use best endeavours to prevent the misuse of Confidential Information by others. 17.3 All Confidential Information and Copies shall be the property of the Company and the Executive shall not make any Copies save in the proper course of their employment. 17.4 Save as authorised by the Board, the Executive shall not make or publish any comment regarding to the business of any Group Company or any of its current or former employees or directors to the media (including on social media). 18. Whistleblowing 18.1 It is the duty of the Executive to report to the Board any material breach by any Group Company of their legal obligations of which the Executive is aware. Concerns should be reported, in writing, to the Board. 18.2 Whilst it is the Company’s clear policy to operate in an ethical and lawful manner and to foster an environment which facilitates the internal reporting of matters of concern for the avoidance doubt nothing in this Agreement prevents the Executive from making a "protected disclosure" within the meaning of Part 4A (Protected Disclosures) of the Employment Rights Act 1996 nor from reporting any regulatory breaches to any regulator or from reporting any criminal conduct to the relevant authorities.

11 4135-1945-7548, v. 3 19. Intellectual Property 19.1 The Executive shall disclose (voluntarily) to the Company details of all Inventions and of all works embodying Intellectual Property Rights made solely or jointly with others at any time in the course of employment which relate to, or are capable of being used in, the business of any Group Company whether or not in the course of their ordinary duties and whether or not made in working time (together, the “Company IP”). The Executive acknowledges that all Intellectual Property Rights subsisting (or which may in the future subsist) in such Company IP shall automatically, on creation, vest in the Company absolutely. To the extent that the Company IP does not vest automatically in the Company the Executive hereby assigns all right, title and interest in the Company IP to the Company with full title guarantee by way of a present assignment of all future rights and shall otherwise hold them on trust for the Company. The Executive agrees promptly to execute all documents and to do all acts as may, in the opinion of the Company, be necessary or desirable to give the Company full benefit of this clause. 19.2 Nothing in this Agreement obliges the Company to seek patent or other protection or to exploit any Invention disclosed by the Executive in accordance with clause 19.1 19.3 The Executive acknowledges that, save as provided by s40 Patents Act 1977, no further remuneration or compensation is or may become due to you as a result of the performance of your obligations under this clause 19. 19.4 The Executive irrevocably waives all “moral rights” under the Copyright, Designs and Patents Act 1988 (and, to the fullest extent permitted by law, all similar rights in other jurisdictions) which the Executive has or will have in any Company IP. 19.5 By way of security for the Executive’s obligations under this Agreement, the Executive irrevocably appoints the Company to be the Executive’s attorney to execute any instrument or to do anything and generally to use the Executive’s name for the purpose of giving the Company or its nominee the benefit of this clause. The Executive acknowledges in favour of a third party that a certificate in writing signed by the Company that any instrument or act falls within the authority conferred by this clause shall be conclusive evidence that such is the case. 20. Payment in Lieu of Notice 20.1 The Company may, in its sole and absolute discretion, terminate the Executive’s employment under this Agreement at any time and with immediate effect by notifying the Executive that the Company is exercising its right under this clause 19 and that it will make a payment in lieu of notice ("PILON") to the Executive. The Executive’s employment will terminate immediately and any PILON due to the Executive in accordance with the provisions of this clause 20 will be paid within 28 days. The PILON will be equal to the basic salary (as at the Termination Date) which the Executive would have been entitled to receive under this Agreement during the notice period referred to at clause 2 (or, if notice has already been given, during the remainder of the notice period) and (ii) the target annual bonus of 60% of basic salary (or the target percentage then in effect as determined by the Board for the applicable year in which the termination occurs) for the year in which the termination occurs, less deductions required by law. 20.2 The Executive shall have no right to receive a PILON unless the Company has exercised its discretion in clause 20.1

12 4135-1945-7548, v. 3 20.3 Notwithstanding clause 20.1, the Executive shall not be entitled to any PILON if the Company would otherwise have been entitled to terminate the Executive’s employment under this Agreement without notice in accordance with clause 21. In that case the Company shall also be entitled to recover from the Executive any PILON already made. 20.4 Notwithstanding anything to the contrary herein, the following provisions apply to the extent the Executive is subject to U.S. income tax and the PILON provided herein is subject to Section 409A of the U.S. Internal Revenue Code (the “Code”) and the regulations and other guidance thereunder and any state law of similar effect (collectively “Section 409A”). The PILON shall not commence until the Executive has had a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “separation from service”). Each instalment of the PILON is a separate “payment” for purposes of Treas. Reg. Section 1.409A-2(b)(2)(i), and the PILON is intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9). However, if such exemptions are not available and the Executive is, upon separation from service, a “specified employee” for purposes of Section 409A, then, solely to the extent necessary to avoid adverse personal tax consequences under Section 409A, the timing of the PILON shall be delayed until the earlier of (i) six (6) months and one day after your separation from service, (ii) your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of such applicable Section 409A period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to the Executive, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement. No interest shall be due on any amounts so deferred. The parties acknowledge that the exemptions from application of Section 409A to the PILON are fact specific, and any later amendment of this Agreement to alter the timing, amount or conditions that will trigger payment of the PILON may preclude the ability of the PILON provided under this Agreement to qualify for an exemption. To the extent that the PILON or other benefits are deferred compensation under Section 409A, and are not otherwise exempt from the application of Section 409A, then, if the period during which the Executive may consider and sign the Release spans two calendar years, the payment of such severance payments and benefits will not be made or begin until the later calendar year. It is intended that this Agreement shall comply with the requirements of Section 409A, and any ambiguity contained herein shall be interpreted in such manner so as to avoid adverse personal tax consequences under Section 409A. Notwithstanding the foregoing, the Company shall in no event be obligated to indemnify the Executive for any taxes or interest that may be assessed by the Internal Revenue Service pursuant to Section 409A of the Code to payments made pursuant to this Agreement. 21. Termination Without Notice 21.1 The Company may terminate the Executive’s employment under this Agreement with immediate effect without notice and with no liability to make any further payment to the Executive (other than in respect of amounts accrued at the Termination Date) if in the reasonable opinion of the Board the Executive: 21.1.1 is guilty of gross misconduct; or 21.1.2 commits any serious or repeated breach or non-observance of any of the provisions of this Agreement or refuses to comply with any reasonable and lawful directions of the Company; or

13 4135-1945-7548, v. 3 21.1.3 is grossly negligent or grossly incompetent in the performance of their duties; or 21.1.4 is declared bankrupt or makes any arrangement with or for the benefit of their creditors or has a county court administration order made under the County Court Act 1984; or 21.1.5 is convicted of any criminal offence (other than an offence under any road traffic legislation in the United Kingdom or elsewhere for which a fine or non-custodial penalty is imposed); or 21.1.6 has breached the Quoted Company Requirements; or 21.1.7 is disqualified from acting as a director or resigns as a director from the Company or any Group Company without the prior written approval of the Board; or 21.1.8 is no longer eligible to work in the country in which the Executive’s usual place of work is located; or 21.1.9 is guilty of any fraud or dishonesty or acts in any manner which brings or is likely to bring the Executive or any Group Company into disrepute or is materially adverse to the interests of any Group Company. 21.2 The rights of the Company under clause 21.1 are without prejudice to any other rights that it might have at law to terminate the Executive’s employment or to accept any breach of this Agreement by the Executive as having brought the Agreement to an end. Any delay by the Company in exercising it rights to terminate shall not constitute a waiver thereof. 21.3 The Company may suspend the Executive from any or all of the Executive’s duties during any period in which the Company is investigating any disciplinary matter involving the Executive or while any disciplinary procedure or regulatory investigation is outstanding. Any such suspension shall not constitute disciplinary action. During any period of suspension, the Company may impose the same conditions that apply to Garden Leave. 22. Garden Leave 22.1 Following service of notice to terminate the employment by either party, or if the Executive purports to terminate the employment in breach of contract, the Company may by written notice place the Executive on Garden Leave for the whole or part of the remainder of the employment. 22.2 During any period of Garden Leave: 22.2.1 the Company shall be under no obligation to provide any work to the Executive and may revoke any powers the Executive holds on behalf of any Group Company; 22.2.2 the Company may require the Executive to carry out alternative duties or to only perform such specific duties as are expressly assigned to the Executive, at such location (including the home of the Executive) as the Board may reasonably decide;
