| | (c) | life assurance against death and disability subject to the terms and conditions of such scheme as may be in force from time to time and as at the date hereof as
detailed in schedule 2 (the Scheme). The Company may substitute another provider or alter the benefits available to the Executive under, or the terms and conditions of, the Scheme at any time on reasonable notice to the Executive
PROVIDED THAT:
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | any such substituted, altered or varied benefit shall be no less favourable in the aggregate than that in effect on the date hereof; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | in the event that life assurance cover for the Executive is refused by the provider or any conditions or limitations to the benefit are applied by the provider, the
Company hereby agrees to pay such sum in such manner as shall provide a benefit that is, in aggregate with any payment made under the Scheme, equal to three times annual salary as detailed under the terms of the Scheme.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company shall pay the premium from time to time required by the provider and pay the Executive such sums (if any) as may from time to
time be received by the Company from the provider in respect of any claim made by the Executive under the Scheme. Full details of the Scheme are available from the Company Secretary..
