CHANGE OF CONTROL 18.1 A person has "Control" of a company if he holds, directly or indirectly, shares which together with shares held by any persons acting in concert with him carry 50% or more of the voting rights of that company and "Change in Control" shall be construed accordingly. In the event of a hostile take-over offer being made to acquire all the shares with voting rights in the Company within 36 months of the date of this Agreement, then a Change of Control shall be deemed to have taken place on the announcement by or on behalf of the hostile offeror (who must also be a hostile offeror on the date of such announcement) that such offer is or has become unconditional in all respects. This clause 18 will not apply in the event of a Change of Control which is recommended to shareholders by a majority of the Board. 9 18.2 If at any time during the period of [6] months following a hostile offer becoming unconditional in all respects ("the Operative Period") the Executive is either dismissed by the Company or the Executive elects to treat such Change in Control as a breach of this Agreement provided that you serve notice in writing on the Company of your election to treat such Change of Control as a breach of this Agreement before the expiry of the Operative Period ("Special Notice"), on service of which your employment shall terminate. The Company shall upon your either being dismissed by the Company or upon service of the Special Notice pay to you on the date of termination by way of liquidated damages a sum equal to 2 years' basic salary ("the Severance Payment"). The Severance Payment shall be the only payment which the Company shall make to you as compensation for the termination of your employment and for the termination of any office which you hold in the Company or in any company in the Professional staff group. For the avoidance of doubt, if Special Notice is not served by you within the Operative Period, you shall be deemed to have waived any breach of this Agreement pursuant to this clause 18 and shall have no right or entitlement to the Severance Payment. 18.3 The payments to be made to you pursuant to this clause 18 shall be subject to such deductions as the Company is obliged to make by law. In the event of you becoming entitled to receive the Severance Payment as provided for in this clause 18 you hereby agree that you shall not be entitled to any further or additional compensation of any kind whatsoever and, in the event of payment being made to you under this clause 18, waive, release and discharge any and all such rights and claims which you may have against the Company or any company in the Professional Staff group of companies under this Agreement or arising as a consequence of its termination. 18.4 In the event of payment being made to you under this clause 18, you shall resign forthwith from all office holdings and at the request of the Company enter into a written compromise agreement with the Company which meets the requirements of section 203 of the Employment Rights Act 1996 (as modified or re-enacted) and which compromises in full and final settlement on the basis of the Severance Payment made under this clause 18 all or any statutory or contractual claims which you have or may have against the Company or any Group Company arising from this Agreement save for any claims in respect of your accrued pension rights and any claim for personal injury. 18.5 The parties agree that the calculation of the Severance Payment referred to in sub-clause 18.2 represents a genuine pre-estimate of damages payable to you upon the termination of your employment and any office holding in the company or in any company in the Professional Staff group. 18.6 For the avoidance of doubt a Special Notice shall be of no effect if served at a time when you have committed or are under investigation for acts or omissions 10 which would entitle the Company to dismiss you instantly pursuant to sub- clause 16.1. 19. RESIGNATION FROM OFFICES On the termination of your employment for whatever reason, you will at the request of the Company resign (without prejudice to any claims which you may have against any company arising out of this Agreement or the termination thereof) from all and any offices which you may hold in the Company or any group company and from all other appointments or offices which you hold as nominee or representative of the Company or any group company.
