1.   CONTINUITY OF EMPLOYMENT

     Your period of continuous employment with the Employer began on the date
     specified on page 1. Employment with any previous employer does not count
     as part of your period of continuous employment.

2.   JOB DESCRIPTION

     You are employed in the capacity specified on page 1 but it is expected
     that if necessary you may be required to undertake other work of which you
     are capable and/or for which you have trained or will receive training from
     the Employer.

3.   SALARY

     Your salary is paid by bank credit transfer at monthly intervals as
     specified on page 1, one month in arrears. Salaries will be reviewed
     annually.

4.   TRAVEL/EXPENSES

     You may from time to time be expected to travel on behalf of the Company.
     All travel and subsistence expenses wholly and necessarily incurred by you
     on the Employer's business will be reimbursed on production of the relevant
     receipts and vouchers.

5.   HOURS OF WORK

     Your basic hours of work are those specified on page 1.

     You will be required to work such hours as are necessary for the proper

6.   ANNUAL HOLIDAYS

     The holiday year runs from 1 January to 31 December. Up to 5 days can be

     If employment commences or terminates during a specific holiday year,

     worked, pro rata on the basis of completed calendar months.

     If at the time of termination of employment you have exceeded your holiday
     entitlement, your final payment will be reduced accordingly.

     In any event you must give at least four weeks notice of your intention to
     take a holiday, and the Employer, whilst making every effort to meet your
     wishes, reserves the right to refuse permission if your absence would
     result in inadequate staffing.

7.   SICKNESS AND INJURY

     If you are late for work, or absent from whatever cause, a telephone call
     should be made by you or by someone on your behalf. Notification should be
     made as soon as possible to inform the Employer (HR Manager) of the reason
     for absence and the probable length of time you will be absent.

     If you are absent from work due to sickness or injury which continues for
     more than seven days (including weekends) you must provide the Employer
     with a Medical certificate on the eighth day of sickness or injury.
