The Code is separate from the insider dealing provisions contained in Part V of the Criminal Justice Act 1993 and from the market abuse provisions contained in MAR as amended from time to time and the Executive may not at any time enter into any transaction or make any statement which contravenes those Acts irrespective of whether this should also breach the Code; and

Breach of the provisions of this Clause 4.16 shall constitute a fundamental breach of the Executive’s obligations under this Agreement for the purposes of Clause 18.1 (Termination for Cause) below.

4.18        The Executive’s initial primary place of employment shall be the Group’s premises at Birmingham, Alabama.

To the extent that such Intellectual Property Rights are not otherwise vested in the Company, the Executive hereby assigns the same to the Company, together with all related past and future rights to action.

5.2          It shall be part of the normal duties of the Executive to consider in what manner and by what new methods or devices, products, services, processes, equipment or systems of the Company and each Group Company might be improved, and promptly to give to the Board full details of any invention, discovery, design, improvement or other matter or work whatsoever in relation thereto which the Executive may from time to time make or discover during the course of the Executive’s employment with the Company, and to further the interests of the Company in relation to the same.

5.3          The Executive shall at the request and cost of the Company do all things necessary or desirable and execute all and any documents required to give the Company, or such other member of the Group as the Company may nominate, title to the Intellectual Property Rights vested or assigned under Clause 5.1. The obligation contained in this Clause 5.3 shall continue to apply after the termination of the Executive’s employment with the Company without limit in point of time. In addition, by entering into this Agreement the Executive irrevocably appoints the Company to act upon his behalf to execute any document and do anything in the name of the Executive for the purpose of giving the Company or its nominee the full benefit of this Clause 5 or the Company’s entitlement under statute.

5.6          The Executive must not knowingly do or omit to do anything which will or may have the result of preventing the Company from enjoying the full benefits of ownership of the Intellectual Property Rights vested or assigned under Clause 5.1.

5.7          The Executive must not at any time make use of the Company’s property or documents or materials in which the Company owns the Intellectual Property Rights for any purpose which has not been authorised by the Company.

5.8          Each of the provisions of this Clause 5 is distinct and severable from the others and if at any time one or more of such provisions is or becomes invalid, unlawful or unenforceable (whether wholly or to any extent), the validity, lawfulness and enforceability of the remaining provisions (or the same provision to any other extent) of this Clause 5 shall not in any way be affected or impaired.

6             CONFIDENTIALITY

6.1          During the course of the Employment, the Executive will have access to and become aware of information which is confidential to the Company. Without prejudice to his common law duties, the Executive undertakes that he will not, save in the proper performance of his duties, make use of, or disclose to any person, (including for the avoidance of doubt any competitors of the Company), any of the trade secrets or other confidential information of or relating to the Company, and/or any user of the Company’s services and/or to any company, organisation or business with which the Company is involved in any kind of business venture or partnership, or any other information concerning the business of the Company which he may have received or obtained in confidence while in the service of the Company. The Executive will use his best endeavours to prevent the unauthorised publication or disclosure of any such trade secrets or confidential information.

6.2          This restriction shall continue to apply after the termination of the Executive’s employment without limit in point of time but, both during the Executive’s employment and after its termination, shall cease to apply to information ordered to be disclosed by a court or tribunal of competent jurisdiction or otherwise required to be disclosed by law or to information which becomes available to the public generally (other than by reason of the Executive breaching this Clause 6). Nothing in this Clause 6 will prevent the Executive making a “protected disclosure” within the meaning of the Public Interest Disclosure Act 1998 or any other similarly applicable law in any other jurisdiction.

8.1          In order to keep and maintain records relating to the Employment it shall be necessary for the Company to record, keep and process personal data (including sensitive personal data) relating to the Executive. This data may be recorded, kept and processed on computer and in hard copy form. To the extent that it is reasonably necessary in connection with the Employment and the performance of the Company’s responsibilities as an employer, the Company may be required to disclose this data to others, including other employees of the Company, Group Companies, the Company’s professional advisers, Her Majesty’s Revenue and Customs, the Internal Revenue Service of the United States and other authorities. The Executive consents to the recording, processing, use and disclosure by the Company of personal data relating to the Executive as set out above. This does not affect the Executive’s rights as a data subject or the Company’s obligations and responsibilities under the Data Protection Act 1984 and/or the Data Protection Act 1998.

8.2          The Executive acknowledges that for the purposes of the Company’s administration the Company processes certain personal information concerning the Executive.

8.3          The Executive gives his consent to the processing of data for the purposes of diversity monitoring.

Such salary shall include any sums receivable as Director’s fees or other remunerations from any Group Company. The undertaking of a salary review does not confer a contractual right (whether express or implied) to any increase in salary. An increase in salary one year will not guarantee an increase in salary in any subsequent year or years. For avoidance of doubt, the Executive confirms that any compensation and benefits to which he is entitled under this Agreement or otherwise received from the Group are subject to any and all applicable withholding and deductions for tax and social security contributions and any other applicable withholdings and deductions under all applicable laws.

10.2        Payment of salary to the Executive may be made either by the Company or by another Group Company and, if by more than one company, in such proportion as the Board may from time to time decide.

10.3        The Executive agrees as a term of the Employment with the Company that the Company will be entitled at any time during the Employment or in any event on the termination of the Employment to deduct from his actual total compensation any monies due from him to the Company including but not limited to:

11.1        The Company shall refund the Executive all reasonable expenses wholly and exclusively incurred by him in the proper performance of the Company’s or the Group’s business provided that the Executive produces to the Company such evidence of actual payment as the Company reasonably requires. Any credit card or similar facility supplied to the Executive by the Company shall be used solely for expenses incurred by him in the course of the Employment.

11.2        The Company reserves the right in its sole discretion not to reimburse expenses incurred within 30 days of the Executive giving notice to resign or terminate the Employment, unless authorised in advance by the Company.

11.3        For the duration of his Employment, the Company shall provide the Executive with an office at his normal place of work, a personal computer for business use, and such other equipment or resources as are reasonably necessary to enable to the Executive to carry out his duties pursuant to this Agreement.

12           CAR ALLOWANCE

12.1        Whilst the Executive remains employed by the Company, he will be eligible for a car allowance of US$1000 per month for up to the first 24 months of his Employment pursuant to this Agreement. The car allowance shall be subject to withholdings and deductions for tax and social security contributions and any other applicable withholdings and deductions under all applicable laws.

13           WORKING HOURS, HOLIDAYS AND VACATION

13.1        The Company’s usual business hours are Monday to Friday, 8.00 am to 5.00 pm (US Central Standard Time or Eastern Time, as applicable based upon the Executive’s location, when working in the US), although the Company reserves the right to vary these start and finish times according to business needs.

13.2        The Executive shall devote the whole of his time, attention and abilities to his duties hereunder during the Company’s usual business hours and such additional hours as may from time to time be reasonably necessary for the proper performance of his duties. This may include working in the evenings outside normal office hours, at weekends or on public holidays. The Executive shall not be entitled to receive any additional remuneration for work outside the Company’s usual business hours.

13.3        The Executive shall be entitled to paid public holidays recognized by the Group applicable to employees of the Group located in the United States generally and to paid vacation in accordance with the policies of the Group applicable to other employees of the Company located in the United States generally, but not more than twenty (20) days of paid vacation. Any vacation shall be taken at such reasonable time or times as the Board may approve and the Executive shall use reasonable efforts to schedule vacation at times that does not cause unnecessary disruption to the Group’s operations. Vacation may only be taken during the notice period if either the Company so requires or the Board has approved the holiday after notice has been served.

13.4        Vacation entitlement shall accrue pro rata during each Holiday Year. Any entitlement to vacation remaining at the end of any Holiday Year may not be carried forward to the next succeeding Holiday Year.

13.5        If the Executive has vacation entitlement accrued but not taken, the Company may, in its sole discretion, require him to take some or all of his vacation entitlement during his notice period or pay him a sum in lieu of accrued holiday on termination. If, on the termination of the Employment, the Executive has exceeded his accrued holiday entitlement, the Company reserves the right to deduct the cost of such excess from any sums due to the Executive from the Company. A day’s holiday pay for these purposes shall be 1/260 of the Executive’s annual basic salary at the relevant time.

13.6       The Company may require the Executive to take holidays at a certain time and for a specified period of time if, for example, regulatory reasons or local business reasons make this advisable.

14           BENEFITS

14.1        Subject to each arrangement’s eligibility requirements, Executive shall be entitled to participate in all employee benefit plans, programs, practices or arrangements of the Company in which other employees of the Company located in the United States are eligible to participate from time to time, including, without limitation, any qualified or non-qualified pension, profit sharing and savings plans, any death benefit and disability benefit plans, and any medical, dental, health and welfare insurance plans.

14.2        Any payments made under the schemes or plans referred to in Clause 14.1 shall cease upon the termination of the Executive’s Employment for whatever reason. The provision of any insurance scheme does not in any way prevent the Company from lawfully terminating the Employment in accordance with the provisions of this Agreement, even if to do so would deprive the Executive of membership of, or cover under any such insurance scheme and even if the Executive is still in receipt of benefits under the provisions of any such scheme or plan at the date of termination of the Employment.

14.3        The Company shall maintain for the Executive Directors’ and Officers’ insurance in respect of those liabilities which he may incur as a director or officer of the Company or any other Group Company for which such insurance is normally available to the Company in respect of its directors.

14.4        The Company reserves the right to terminate its participation in the schemes or plans referred to in this Clause 14 or to substitute other schemes or plans or to alter the benefits available under any scheme or plan. In the event of reduction or discontinuance of any scheme or plan provided for in this Clause 14 or any of such scheme benefits or plan benefits, the Company shall be under no obligation to replace the same with identical or similar such benefits. For the avoidance doubt, this Clause 14.4 shall be without prejudice to the Executive’s entitlement to benefits otherwise expressly provided for by this Agreement.

15            ILL-HEALTH OR INJURY

15.1        The Executive shall be entitled to ten 10 days of paid sick leave (based on base salary only) for the care of the Executive or other immediate family member per calendar year. If the Executive is absent from work on medical grounds, he is required to notify the Company by telephone on the first morning of his absence or as soon as reasonably practicable thereafter. If the absence continues the Executive is under a duty to keep the Company informed at least once a week of the current state of his health, the progress of any treatment being undertaken, and the likely date of return to work. If the Executive is absent from work for more than seven (7) consecutive days, he must submit to the Company a medical certificate signed by a practising medical practitioner. Thereafter, the Executive shall submit further medical certificates to cover the whole of his period of absence. Upon the Executive informing the Company that he is well enough to return to work, the Company reserves the right to require the Executive to produce a report from his own medical practitioner or an independent doctor nominated by the Company, whichever may be required by the Company, to certify the Executive’s fitness to return. On his return to work the Executive shall, in any event, complete a self-certification sickness form.

15.2        Notwithstanding the wider provisions of this Agreement, in the event that the Executive is incapacitated by reason of ill health or accident from performing his duties hereunder for a period or periods exceeding 90 working days in any 12 month period then:

15.3        Where the Executive’s employment terminates pursuant to Clause 15.2(b), he shall be entitled to be paid his Accrued Obligations in a lump sum within forty-five (45) days following the termination of his employment. Where the Company exercises its right to pay in lieu of notice, he shall be entitled to be paid in lieu of his thirteen week notice entitlement at the same time.

15.4        It is a condition of the Employment that the Executive consents to an examination by an independent doctor nominated by the Company or Company doctor if the Company doctor has not previously had care of the Executive should the Company so require.

15.5        This Clause 15 shall be subject to all applicable employment laws in force in the United States including but not limited to the Family Medical Leave Act, and American with Disabilities Act.

16           DISCIPLINARY AND GRIEVANCE PROCEDURES

18.2        If Executive’s employment is terminated for Cause by the Company, Executive shall be entitled to receive payment of the sum of:

19.3        On the termination of the Employment, howsoever arising, the Executive shall forthwith or at any time thereafter at the request of the Company, resign from all offices held by him in any company in the Group (including all directorships) together with any other offices or memberships held by him by virtue of the Employment.

19.5        The Executive shall not knowingly at any time during or after the termination of the Employment make any untrue or misleading statement in relation to the Company or the Group nor, in particular, after the termination of the Employment represent himself as being employed by or connected with the Group.

The payment in lieu of notice shall be calculated by paying the Executive’s ordinary salary in lieu of notice. The Company shall not, under any circumstances, be obliged to make a payment in lieu of notice.

20.2        For the avoidance of doubt, where the Company exercises its right to make a payment in lieu of the balance of the Initial Employment Period (if any) and the Executive’s notice entitlement, the Executive shall additionally be entitled to be paid for the Accrued Obligations.

20.3        If either party serves notice on the other to terminate the Employment, the Company may require the Executive to take “garden leave” for all or part of the remaining period of his employment. If the Executive is asked to take garden leave he:

21           TERMINATION BY THE EXECUTIVE

23           LITIGATION

23.1        The Executive agrees to provide the Company with such reasonable assistance as it may reasonably require in the conduct of any legal proceedings in which the Company or any Group Company is involved and/or in relation to any investigation of the operations or activities of the Company and/or any Group Company by any regulatory, judicial or fiscal body or authority in relation to which the Company reasonably believes that the Executive may be able to provide assistance, subject to the payment by the Company of the Executive’s reasonable expenses incurred in providing such co-operation and the Company shall also compensate the Executive at reasonable rates for any loss of income he/she incurs as a result of providing such co-operation.
