22.1.

Notwithstanding clause 2, the Company may, in its sole and absolute discretion, terminate the Appointment at any time and with immediate effect by notifying the Employee that the Company is exercising its right under this clause 22 and that it will make within 28 days a payment in lieu of notice (Payment in Lieu), or the first instalment of any Payment in Lieu, to the Employee. This Payment in Lieu will be equal to the basic salary (as at the date of termination) which the Employee would have been entitled to receive under this Agreement during the notice period referred to at clause 2 (or, if notice has already been given, during the remainder of the notice period) less income tax and National Insurance contributions. For the avoidance of doubt, the Payment in Lieu shall not include any element in relation to:

22.1.1.

any bonus or commission payments that might otherwise have been due during the period for which the Payment in Lieu is made;

22.1.2.

any payment in respect of benefits which the Employee would have been entitled to receive during the period for which the Payment in Lieu is made; and

22.1.3.

any payment in respect of any holiday entitlement that would have accrued during the period for which the Payment in Lieu is made.

22.2.

The Company may pay any sums due under clause 22.1 in equal monthly instalments until the date on which the notice period referred to at clause 2 would have expired if notice had been given. The Employee shall be obliged to seek alternative income during this period and to notify the Company of any income so received. The instalment payments shall then be reduced by the amount of such income.

16


22.3.

The Employee shall have no right to receive a Payment in Lieu unless the Company has exercised its discretion in clause 22.1. Nothing in this clause 22 shall prevent the Company from terminating the Appointment in breach.

22.4.

Notwithstanding clause 22.1 the Employee shall not be entitled to any Payment in Lieu if the Company would otherwise have been entitled to terminate the Appointment without notice in accordance with clause 23. In that case the Company shall also be entitled to recover from the Employee any Payment in Lieu (or any instalments) already made.

23.
