7 Base Salary and Benefits

7.1 The Company will pay the Executive an annual base salary of USD 1,000,000.

Salary will be reviewed annually, normally commencing in June of each year. The first review will take place in June 2015.

7.2.1 The first instalment of USD 250,000 will be paid within one month of the Commencement Date; and

7.2.2 The second and final instalment of USD 250,000 will be paid one year following the Commencement.

A18771805/1.0/12 May 2015

Both instalments are non-pensionable, but are subject to applicable tax withholdings.

7.3 The salary referred to in Clause 7.1 will be inclusive of any remuneration or fees which the Executive is or becomes entitled to as an office holder in the Company or any Group Company or any other company in which the Executive becomes an office holder as part of or in connection with his duties under this Agreement. To achieve this:

7.3.1 the Executive will repay any fees he receives to the Company; or

7.3.2 his base salary will be reduced by the amount of those fees; or

7.3.3 a combination of the methods set out in Clauses 7.3.1 and 7.3.2 will be applied.

7.4 The Executive may, at the discretion of the Remuneration Committee of the Board, be invited to participate in any bonus plan operated by the Company from time to time. If so invited, the Executive’s participation in such bonus plan and the amount (if any) payable under it will be at the discretion of the Remuneration Committee and/or in accordance with the rules of that plan from time to time in force. Participation in a bonus plan for one year does not entitle the Executive to participation in any bonus plan for any other year.

7.5 In order to comply with remuneration laws, rules, regulations or applicable regulatory requirements or guidance, any variable pay which the Executive is awarded may be subject to reduction (i.e. “malus” or “performance adjustment”) or recovery (i.e. “clawback”). The terms of such reduction or recovery will be communicated to the Executive at the time of award. By signing this Agreement the Executive agrees to such reduction or recovery in respect of any variable pay which the Executive is awarded.

7.6 The Executive shall be eligible to participate in the Company’s Defined Contribution Pension Plan and Defined Contribution Supplemental Retirement Plan in accordance with their respective terms and conditions.

7.7 The Executive is entitled to 25 days’ paid vacation each year in accordance with the Company’s vacation policy.

7.8 The Executive shall be eligible to participate in employee benefit and welfare plans, including plans providing retirement benefits, medical, dental, hospitalization, life or disability insurance, on the same basis as provided to similarly situated senior executives of the Parent (except as determined by the Remuneration Committee of the Board). For purposes of this Agreement, “employee benefit and welfare plans” do not include any severance, termination or redundancy plan, program or arrangement operated by any member of the Group.

7.9 The Executive will receive an annual allowance of USD 8,000 towards financial planning and/or tax preparation advice. This annual allowance will be paid to the Executive in January each year.

7.10 The Executive will also be eligible for relocation benefits in accordance with the Company’s Relocation Policy. For the avoidance of doubt, this includes a payment or payments to cover the cost of a rental property in Waltham area for a period up to six months.

8 Expenses

8.1 The Company will refund to the Executive all reasonable expenses properly incurred by him in performing his duties under this Agreement, provided that these are incurred in accordance with Company policy from time to time. The Company will require the

A18771805/1.0/12 May 2015

4

Executive to produce receipts or other documents as proof that he has incurred any expenses he claims.

8.2 If the Executive is provided with a credit or charge card by the Company this must only be used for expenses which he incurs in performing the duties of the Employment.

9 Confidentiality

9.1 Without prejudice to the common law duties which he owes to the Group the Executive agrees that he will not, except in the proper performance of his duties, copy, use or disclose to any person any of the Group’s trade secrets or confidential information. This restriction will continue to apply after the termination of the Employment without limit in time but will not apply to trade secrets or confidential information which become public other than through unauthorized disclosure by the Executive. The Executive will use his best endeavours to prevent the unauthorized copying, use or disclosure of such information.

For the purposes of this Agreement, trade secrets and confidential information include but will not be limited to technical data, know-how, information technology and know-how relating to the Group, customer lists, pricing information, information relating to the Group’s marketing and financial strategies, marketing materials, financial information and any other information concerning the affairs of the Group or the personnel of the Group which is for the time being confidential, which the Executive is told is confidential or which by its nature is obviously confidential and whether such information is in written, oral, visual, electronic or any other form.

9.2 In the course of the Employment the Executive is likely to obtain trade secrets and confidential information belonging or relating to other Group Companies and other persons. He will treat such information as if it falls within the terms of Clause 9.1 and Clause 9.1 will apply with any necessary amendments to such information. If requested to do so by the Company the Executive will enter into an agreement with other Group Companies and any other persons in the same terms as Clause 9.1 with any amendments necessary to give effect to this provision.

9.3 Nothing in this Agreement should or will prevent the Executive from raising any concerns in accordance with the provisions of the National Grid Standards of Ethical Business Conduct and the Requirement for Written Codes of Ethics for Employees (incorporating Whistleblowing Protection), or from disclosing confidential information as required by applicable law.

10 Intellectual Property

10.1 The Executive must disclose immediately to the Company any discovery or invention, secret process or improvement in procedure made or discovered by the Executive during his employment in connection with or in any way affecting or relating to the business of the Company or any Group Company or capable of being used or adapted for use in or in connection with any such company (“Inventions”) which Inventions will belong to and be the absolute property of the Company or such other person, firm, company or organization as the Company may require.

10.2 If requested by the Board (whether during or after the termination of his employment) the Executive will at the expense of the Company apply or join in applying for letters patent or other similar protection in the United States, the United Kingdom or any other part of the world for all Inventions and will do everything necessary (including executing

A18771805/1.0/12 May 2015

5

documents) for vesting letters patent or other similar protection when obtained and all right and title to and interest in all Inventions in the Company absolutely and as sole beneficial owner or in such other person, firm, company or organization as the Company may require.

10.3 The Executive will (both during and after the termination of his employment) at the Company’s expense anywhere in the world and at any time promptly do everything (including executing documents) that may be required by the Board to defend or protect for the benefit of the Company all Inventions and the right and title of the Company to them.

10.4 The entire copyright and all similar rights (including future copyright, the right to register trade marks or service marks and the right to register designs and design rights) throughout the world in works of any description produced by the Executive in the course of or in connection with his employment (“Works”) will vest in and belong to the Company absolutely throughout the world for the full periods of protection available in law including all renewals and extensions.

10.5 The Executive will (both during and after the termination of his employment) at the Company’s request and expense anywhere in the world and at any time promptly do everything (including executing documents) that may be required by the Board to assure, define or protect the rights of the Company in all Works.

10.6 The Executive will not make copies of any computer files belonging to any Group Company or their service providers and will not introduce any of his own computer files into any computer used by any Group Company in breach of any Group Company policy, unless he has obtained the consent of the Board.

10.7 By entering into this Agreement the Executive irrevocably appoints the Company to act on his behalf to execute any document and do anything in his name for the purpose of giving the Company (or its nominee) the full benefit of the provision of Clause 10 or the Company’s entitlement under statute. If there is any doubt as to whether such a document (or other thing) has been carried out within the authority conferred by this Clause 10.7, a certificate in writing (signed by any director or the secretary of the Company) will be sufficient to prove that the act or thing falls within that authority.

11 Termination and Suspension

11.1 The Employment will continue until terminated by either party giving written notice as set out in Clause 11.2.

11.2 Either party may terminate the Employment by giving not less than 12 months’ written notice to the other.

11.3 Except as otherwise agreed by the Executive and the Company, notwithstanding the other provisions of this Agreement and in particular Clause 11.2, this Agreement will automatically terminate at the end of the Company’s fiscal year in which the Executive’s 65th birthday occurs.

11.4 The Company may at its sole and absolute discretion pay base salary alone (as referred to in Clause 7.1, at the rate in force at the time such payment is made) in lieu of any unexpired period of notice (less any deductions the Company is required by law to make). Any payment by the Company in lieu of any unexpired period of notice will be made as soon as practicable and, in any event, completed no later than the 15th day of the third month following the later of the end of the calendar year or the Company fiscal

A18771805/1.0/12 May 2015

6

year that occurs immediately following initial notice under Clause 11.2. The Executive is not entitled to participate in or benefit from any severance, termination or redundancy plan, program or arrangement maintained by any Group Company; for the avoidance of doubt, this is notwithstanding anything to the contrary that may be contained in such severance, termination or redundancy plan, program or arrangement.

11.5 Notwithstanding the above, the Company reserves the right to apply a mitigation strategy in respect of any payment in lieu of notice in line with the Company’s remuneration policy and applicable corporate governance requirements from time to time.

11.6 The Company may terminate the Employment by giving written notice to take immediate effect whether or not the Executive’s entitlement to sick pay, contractual or otherwise, has been exhausted if the Executive does not perform the duties of the Employment for a period of 364 days (whether or not consecutive) in any period of two years. This notice can be given whilst the Executive continues not to perform his duties or on expiration of the 364 day period. In this clause, ‘days’ includes Saturdays, Sundays and public holidays.

11.7 The Company may terminate the Employment by giving written notice to take immediate effect if the Executive:

11.7.1 has not performed his duties under this Agreement to the standard required by the Board; or

11.7.2 commits any serious or persistent breach of his obligations under this Agreement; or

11.7.3 does not comply with any material term of this Agreement; or

11.7.4 does not comply with any lawful order or direction given to him by the Board; or

11.7.10 fails to maintain or becomes disqualified from maintaining registration with any regulatory body, membership of which is reasonably required by the Company for the Executive to carry out his duties.

11.8 Where the Company terminates the Employment by giving written notice to take immediate effect in accordance with either Clause 11.6 or 11.7 (or in the case of the

A18771805/1.0/12 May 2015

7

Executive’s death), for the avoidance of doubt there is no obligation to give notice as set out in Clause 11.1 or any other period of notice or to make any payment in lieu of notice.

11.9 The Executive will have no claim for damages or any other remedy against the Company if the Employment is terminated for any of the reasons set out in clause 11.6 or 11.7.

11.10 When the Employment terminates the Company may deduct from any money due to the Executive (including remuneration) any amount which he owes to any Group Company.

11.11 The Company may suspend the Executive from the Employment on full base salary at any time, and for any reason for a reasonable period to investigate any matter in which the Executive is implicated or involved (whether directly or indirectly) and to conduct any related disciplinary proceedings and such suspension shall not entitle the Executive to claim that he has been constructively dismissed.

11.12 As a condition to making the payments and providing the benefits stated in this clause 11, the Company may require the Executive to execute and deliver a general release in which he (i) releases all claims that he may have in respect of his employment against any Group Company and any of their respective past or present officers, directors or employees other than his rights under this Agreement or another agreement into which he and the Company subsequently enter and (ii) covenants that he has not filed and will not file any civil action, suit, arbitration, administrative charge, or legal proceeding against any of the released parties in respect of the released claims.

11.13 Unless the Group waives this requirement, the termination of the Employment for any reason will constitute the Executive’s resignation from (1) any director, officer or employee position he then has with any Group Company and (2) all fiduciary positions (including as trustee) he holds with respect to any pension plans or trusts established by any Group Company. The Executive agrees that this Agreement will serve as his written notice of resignation in this circumstance.

12 Garden Leave

12.1 Neither the Company nor any Group Company is under any obligation to provide the Executive with any work. At any time after notice to terminate the Employment is given by either party under Clause 11 above, or if the Executive resigns without giving due notice and the Company does not accept his resignation, the Company may, at its absolute discretion, require the Executive to take a period of absence called “garden leave” for a maximum period of six months (the “Garden Leave Period”). The provisions of this clause shall apply to any Garden Leave Period.

12.2 The Company may require that the Executive will not, without prior written consent of the Board, be employed or otherwise engaged in the conduct of any activity, whether or not of a business nature during the Garden Leave Period. Further, if so requested by the Company, the Executive will not:

12.2.1 enter or attend the premises of the Company or any other Group Company; or

12.2.2 contact or have any communication with any customer or client of the Company or any other Group Company in relation to the business of the Company or any other Group Company (other than purely social contract); or

A18771805/1.0/12 May 2015

8

12.2.3 contact or have any communication with any employee, officer, director, agent or consultant of the Parent or any other Group Company in relation to the business of the Parent or any other Group Company; or

12.2.4 remain or become involved in any aspect of the business of the Parent or any other Group Company except as required by such companies.

12.3 The Company may require the Executive:

12.3.1 to comply with the provisions of Clause 15; and

12.3.2 to immediately resign from any directorship, trusteeships or other offices which he holds in the Parent, any other Group Company or any other company where such directorship or other office is held as a consequence or requirement of the Employment, unless he is required to perform duties to which any such directorship, trusteeship or other office relates in which case he may retain such directorships, trusteeships or other offices while those duties are ongoing. The Executive hereby irrevocably appoints the Company to be his attorney to execute any instrument and do anything in his name and on his behalf to effect his resignation if he fails to do so in accordance with this Clause 12.3.2.

12.4 During the Garden Leave Period, the Executive will be entitled to receive his base salary and all contractual benefits (excluding bonuses) in accordance with the terms of this Agreement. Any unused vacation accrued at the commencement of the Garden Leave Period and any vacation accrued during any such period will be deemed to be taken by the Executive during the Garden Leave Period.

12.5 At the end of or at any time during the Garden Leave Period, the Company may, in it’s sole and absolute discretion, pay the Executive base salary alone (as defined in Clause7.1) in lieu of the balance of any period of notice given by the Company or the Executive (less any deductions the Company is required by law to make). In any event, and in accordance with Clause 11.4, the Company’s payment in lieu of the unexpired period of notice will be completed no later than the 15th day of the third month following the later of the end of the calendar year or the Company fiscal year that occurs immediately following initial notice under Clause 11.2.

12.6 During the Garden Leave Period:

12.6.1 the Executive shall provide such assistance as the Company or any Group Company may require to effect an orderly handover of his responsibilities to any individual or individuals appointed by the Company or any Group Company to take over his role or responsibilities;

12.6.2 the Executive shall make himself available to deal with requests for information, provide assistance, be available for meetings and to advise on matters relating to work (unless the Company has agreed the Executive may be unavailable for a period); and

12.6.3 the Company may appoint another person to carry out his duties in substitution for the Executive.

12.7 All duties of the Employment (whether express or implied), including without limitation the Executive’s duties of fidelity, good faith and exclusive service, shall continue throughout the Garden Leave Period save as expressly varied by this Clause 12.

12.8 The Executive agrees the exercise by the Company of its rights pursuant to this Clause 12 shall not entitle the Executive to claim that he has been constructively dismissed.
