7.1.1he has no claims against the Company, any Group Company or their employees or officers other than those raised in clause 6.1 (a), (b) and (c); and

8.1The deductions for tax and other statutory deductions made from the Settlement by the Company are in accordance with the Company’s current understanding of the tax regime. However the Executive agrees to be responsible for the payment of any

further tax and other statutory deductions (whether the same are payable in the United Kingdom or elsewhere) in respect of all and any part of the Settlement and to indemnify each and every Group Company (and to keep each and every Group Company indemnified on a continuing basis) against all and any liabilities to taxation or statutory deductions (including any interest, fines, penalties, surcharges, costs and expenses) which they may incur in respect of or by reason of all and any part of the Settlement.

8.2To the extent that the Company or any Group Company incurs any liability to tax in respect of any payment under this indemnity, the Executive shall pay such additional amounts to the Group Company as are required to ensure that the net amount received and retained by the Group Company (after tax) is equal to the full amount which would have been received and retained had no such liability to tax been incurred provided that this clause shall not confer any right on the Company or any Group Company to recover any sums to the extent that recovery of the same is prohibited by law.

Notwithstanding anything herein to the contrary, payment of third-party tax preparation services under this section will only apply with respect to taxes due on payments and other compensation the Executive has received and will receive from the Company and its subsidiaries, and will apply for: (A) any tax periods in which the Executive has received or will receive any such payments or compensation from the Company and its subsidiaries and (B) any tax periods in which the Executive is subject to taxation in the United Kingdom in respect of his employment with the Company and its subsidiaries, termination of employment, or service on the ARO Board as the Company’s designated representative. For the avoidance of doubt, except as expressly set forth in the Company’s expatriate assignment and tax equalization policy, the Executive shall be responsible for any taxes due on payments or benefits

received from the Company and its subsidiaries and the Company shall not provide any tax gross-ups or tax equalization payments to the Executive.

10.2.2by any law or reporting requirement;

10.2.3in order to instruct legal or professional advisers provided that the Executive procures that any such adviser agrees to keep the information confidential;

11.1.3he shall provide the Company with a letter in the form set out in schedule 1 signed by the Adviser.

11.2The Executive understands and acknowledges that the Executive is waiving and releasing any rights the Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”), and that this waiver and release is knowing and voluntary. The Executive understands and agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the Effective Time of this Agreement. The Executive understands and acknowledges that the consideration given for this waiver and release is in addition to anything of value to which the Executive was already entitled.

In the event the Executive signs this Agreement and returns it to the Company in less than the 21 day period identified above, the Executive hereby acknowledges that Executive has freely and voluntarily chosen to waive the time period allotted for considering this Agreement.

No failure to exercise nor any delay in exercising any right or remedy hereunder by the Company or any Group Company shall operate as a waiver thereof or of any other right or remedy hereunder, nor shall any single or partial exercise of any right or remedy by the Company or any Group Company prevent any further or other exercise thereof or the exercise of any other right or remedy.

If any provision or part of a provision of this Agreement shall be or become void or unenforceable for any reason, this shall not affect the validity of that provision or any remaining provisions of this Agreement in this or any other jurisdiction and the

Dear Sirs

Re: [insert name of employer] (the “Company”) and [insert name of employee] (the “Executive”)

We refer to the agreement between the Company and the Executive, our client, dated ______ 201_, a copy of which is attached (the “Settlement Agreement”) and confirm that:

1.    [name of adviser] has given the Executive independent [legal] advice as to the terms and effect of the Settlement Agreement and, in particular, its effect on his ability to pursue his rights before an employment tribunal or court;

2.    [name of adviser] is [a solicitor of the Senior Courts of England and Wales and holds (and held at the time the advice was given) a current practising certificate issued by The Solicitors Regulation Authority;

3.    [firm] holds, and held at the time the advice was given, a current policy of insurance or an indemnity provided for members of a profession or professional body covering the risk of a claim by the Executive in respect of any loss arising in consequence of the advice; and

4.    neither [firm] nor [name of adviser] acted for the Company or any Group Company in relation to the termination of the Executive’s employment with the Company or the Settlement Agreement and we consider [name of adviser] to be an independent adviser for the purposes of section 147 of the Equality Act 2010.

Yours faithfully
