Vesting and Forfeiture .

(a)

The Company hereby grants to Participant on the Grant Date that number of Stock Units (“ Units ”) equal to the “Number of Stock Units” specified in the table above. Subject to Section 1(b), each Unit will vest as to the portion of Units and on the dates specified in the Vesting Schedule on the cover page to this Agreement, so long as your Service to the Company and its Affiliates does not end. The Vesting Schedule is cumulative.

(b)

Vesting of the Units will be accelerated upon the termination of your Service due to death or Disability, and under the circumstances described in Section 5 of this Agreement, and at the discretion of the Committee in accordance with Section 3(b)(2) of the Plan.

(c)

Except as otherwise expressly provided in this Agreement or the Plan, if you cease to continue providing Service to the Company or any Affiliate, then this Award shall terminate and all Units subject to this Award that have not yet vested shall be forfeited by Participant.

(d)

Each Unit that vests will entitle the Participant to receive one Share.

2.

Nature of Units . The Units granted pursuant to this Award are bookkeeping entries only and do not provide the Participant with any dividend, voting or other rights of a shareholder of the Company. The Units shall remain forfeitable at all times unless and to the extent the vesting conditions set forth in this Agreement are satisfied.

3.

Settlement of Units . As soon as practicable after any date on which Units vest, but no later than March 15 of the year following the calendar year in which the vesting date occurs, the Company shall cause to be issued to the Participant (or his or her beneficiary or personal representative) one Share in payment and settlement of each vested Unit. The Company may withhold from the number of such Shares to be delivered in settlement of the Units any Shares required for the payment of taxes as provided in Section 6 below. The Company will pay any original issue or transfer taxes with respect to the issue and transfer of Shares to you pursuant to this Agreement, and all fees and expenses incurred by it in connection therewith. All Shares so issued will be fully paid and nonassessable. Notwithstanding anything to the contrary in this Agreement, the Company will not be required to issue or deliver any Shares prior to the completion of such registration or other qualification of such Shares under any state or federal law, rule or regulation as the Company may determine to be necessary or desirable.

4.

Transfer of Units . You may not assign or transfer the Units other than a transfer upon your death in accordance with your will, by the laws of descent and distribution or pursuant to a beneficiary designation submitted in accordance with Section 6(d) of the Plan. Following any such transfer, the Units shall continue to be subject to the same terms and conditions that were applicable to the Units immediately prior to their transfer.

5.

Change in Control . If, within 12 months of a Change in Control, your Service with the Company and its Affiliates is involuntarily terminated without Cause, or is voluntarily terminated by you for Good Reason (as defined below), and this Award (or a replacement therefor as contemplated by Section 12(b)(1) of the Plan) remains outstanding at the time of such termination, then any unvested portion of the Units (or replacement thereof) shall immediately become vested. For purposes of this Section 5, “Good Reason” means any one or more of the following that occur without your prior written consent:

(a)

a material reduction in your base compensation, other than a reduction that is part of and proportionally consistent with a broad-based reduction in base compensation applicable to Company employees generally;

(b)

a material diminution in your authority, duties or responsibilities;

(c)

a material diminution in the authorities, duties or responsibilities of the supervisor to whom you are required to report, including a requirement that you report to a corporate officer or employee rather than to the Board or a committee thereof;

(d)

a material diminution in the budget over which you retain authority;

(e)

a change in the location of the Company facility or office where you are based to a location more than 50 miles from the Company facility or office where you were based immediately prior to the Change in Control; or

(f)

a material breach by the Company of any terms or conditions of this Agreement or any other agreement between you and the Company, which breach has not been cured by the Company within 15 days after written notice thereof to the Company from you.

In addition to the foregoing, a termination shall be deemed to be for Good Reason only if you notify the Company within 60 days after the later of the occurrence of the event giving rise to Good Reason or your learning of such event, specifically describing such event, and the Company shall have failed to remedy the condition giving rise to such notice within 30 days after such notice has been given.

6.

Taxes . In accepting this Award you agree to indemnify the Company and keep it so indemnified to the extent that it (or, if different your employer at the date a tax charge arises) is required to account for any income tax and/or employee’s National Insurance contributions (or similar social security contributions arising in the U.K. or elsewhere) arising in relation to the issue or transfer to you of Shares pursuant to this Agreement (“ Employee’s Tax Liabilities ”). For the purposes of such indemnity (but without prejudice to the right of the Company to enforce the indemnity in any other way) you agree that the Company (or if different your employer) shall have the right to (i) withhold from any cash payment under the Plan or any other compensation owed to you an amount sufficient to cover all or part of any Employee’s Tax Liabilities, and/or (ii) require you or other person receiving Shares under this Award to pay a cash amount sufficient to cover all or part of any Employee’s Tax Liabilities before actual receipt of those Shares. In lieu of all or any part of a cash payment from you as provided above, the Committee may permit you to cover all or part of any Employee’s Tax Liabilities through a sale of Shares to which you are beneficially entitled on vesting of the Units subject to this Award and for this purpose you appoint such relevant person as the Company may direct as your bare trustee and agent for the purposes of providing the Company with sufficient funds to recover all or part of any Employee’s Tax Liabilities by receiving on trust or retaining on trust (as the case may be) (out of the total number of Shares to which you are beneficially entitled) the legal title to and selling such number of Shares as, in the reasonable opinion of the Company, is required to realise (after any tax and costs payable on such sale) a cash amount equivalent to the Employee’s Tax Liabilities and to pay the amount realised to the Company (or as the Company’s may direct, your employer).

7.
