ABSENCE FROM WORK THROUGH SICKNESS
any period of absence from work due to sickness or injury and subject to the deductions in respect of Statutory Sick Pay or State Sickness Benefit, the Executive's salary will
be paid in full for a period of six (6) months, followed if necessary by a period of six (6) months of half-payment. These periods of payment may be extended at the
discretion of the Chairman, in consultation with the Company's General Medical Services Unit, taking into account the Executive's expected date of return to work.
