6 EXPENSES

The Company shall reimburse all reasonable out of pocket expenses properly incurred by you in the performance of the duties under this Agreement including travelling, subsistence and entertainment expenses provided you follow the Company's guidelines/allowances in force at the relevant time and provided that you shall, where reasonably practicable, provide the Company with vouchers, invoices or such other evidence of such expenses as the Company may reasonably require.

7 HOURS OF WORK

7.1 Your normal working hours are Monday to Friday from 9.00 am to 5.30 pm on each working day with one hour for lunch. You will be required to work such other hours as shall be reasonably necessary for you to perform your duties for which no further remuneration is payable.

7.2 By entering into this Agreement you confirm, that in your capacity as Chief Business Officer you may choose or determine the duration of your working time and the working time limits set out in part II of the Working Time Regulations 1998 do not apply to you.

9 SICKNESS AND OTHER ABSENCE

9.1 If you are unable to attend at work by reason of sickness or injury or any unauthorised reason you must inform the Company as soon as possible on the first day of absence (and in any event not later than 11.00 am on the first day of absence) and, in the case of absence of uncertain duration, you must keep the Company regularly informed of your continued absence and your likely date of return. You are expected to observe this rule very strictly since failure to do so will entitle the Company to stop payment in respect of each day you fail to notify the Company.

9.2 If your absence, due to sickness or injury, is for less than seven (7) days, on your return to work you are required to immediately complete a self-certification form available from the Company.

This doctor's certificate must be provided to the Company promptly following the seventh consecutive day of absence. If illness continues after the expiry of the first certificate, further certificates must be provided promptly to cover the whole period of absence.

9.3 Subject to your compliance with the Company's sickness absence procedures (as amended from time to time), the Company may in its sole and absolute discretion pay full salary and contractual benefits during any period of absence due to sickness or injury for up to an aggregate of 3 months in any fifty-two (52) week period (whether such absence is continuous or intermittent in any calendar year). Such payment shall be inclusive of any statutory sick pay due in accordance with applicable legislation in force at the time of absence. The Company may, in its sole and absolute discretion, extend the period of allowance in an individual case if the circumstances so justify. Thereafter, the Company shall pay statutory sick pay or equivalent benefit to which you may be entitled subject to your compliance with the appropriate rules.

9.4 Whether absent from work or not, you may be, but only on reasonable grounds, required to undergo a medical examination by a Company doctor and your consent will be sought for a report to be sent to the Company.

9.5 The payment of sick pay in accordance with this paragraph 9 is without prejudice to the Company's right to terminate this Agreement prior to the expiry of your right to payments.

9.6 In the event you are incapable of performing your duties by reason of injuries sustained wholly or partly as a result of a third party's actions all payments made to you by the Company as salary or sick pay shall to the extent that compensation is recoverable from that third party constitute loans to you and shall be due and owing when and to the extent that you recover compensation for loss of earnings from the third party.

10.3 By placing you on Garden Leave, the Company will not be in breach of this Agreement or any implied duty of any kind whatsoever nor will you have any claim against the Company in respect of any such action.

10.4 During any period of Garden Leave you will remain readily contactable and available for work save when on paid holiday taken in accordance with paragraph 8. In the event that you are not available for work having been requested by the Company to do so, you will, notwithstanding any other provision of this Agreement, forfeit any right to salary and contractual benefits.

Any delay or forbearance by the Company in exercising any right of termination in accordance with this paragraph 11.3 will not constitute a waiver of such right.

For purposes of this Agreement, Good Reason shall mean that you have complied with the Good Reason Process (hereinafter defined) following the occurrence of any of the following events: (i) a material diminution in your responsibilities, authority or duties; (ii) a material diminution in your Salary; (iii) a material change in the geographic location at which you provides services to the Company; or (iv) the material breach of this Agreement by the Company.

18 DATA PROTECTION

Processing of personal data and our policies

18.1 Information relating to an individual (or from which an individual may be identified) is called personal data.

18.2 In processing personal data, we are required to comply with the law on data protection. To help us achieve this, we have produced a privacy notice (Privacy Notice). This may be found in the Employee Handbook. You must read this and comply with it in carrying out your work.

Data protection principles

18.3 In complying with the law on data protection, we are required to comply with what are known as data protection principles. These are summarised in our Privacy Notice. In performing your role and carrying out your responsibilities, you must do your best to ensure that we comply with these principles.

18.4 A key element of the data protection principles is the duty to ensure that data is processed securely and protected against unauthorised or unlawful processing or loss. Key elements include the following:

(a) You must ensure that laptops, memory sticks, phones and other mobile devices are password protected and encrypted. You must not take such devices outside the office without encryption. You must take care of them and keep them secure.

(b) You must use strong passwords, changing them when asked and not sharing them with unauthorised colleagues.

(c) You must not access other individuals' personal data unless in the course of your work.

Data breach - and urgent notification

18.5 If you discover a data breach, you must notify the Chairman or CFO immediately - and, if practicable, within one hour. Depending on context, you may then need to provide further information on the circumstances of the breach.

18.6 A data breach occurs where there is destruction, loss, alteration or unauthorised disclosure of or access to personal data which is being held, stored, transmitted or processed in any way. For example, there is a data breach if our servers are hacked or if you lose a laptop or USB stick or send an email to the wrong person by mistake.

18.7 Failure to notify a breach or to provide information as set out above will be treated seriously and disciplinary action may be taken.

(a) We process personal data relating to you for the purposes of our business including management, administrative, employment and legal purposes.

(b) We monitor our premises and the use of our communication facilities, including using CCTV cameras, monitoring compliance with our data and IT policies, and where non-compliance is suspected, looking in a more targeted way.

18.9 The summary above is for information only. We do not, in general, rely on your consent as a legal basis for processing. Agreeing the terms of this Agreement will not constitute your giving consent to our processing of your data.

18.10 We reserve the right to amend the documents referred to above from time to time.
