causes the Directors, acting fairly and reasonably, to believe that all or any of the Performance Target(s) are no longer a fair
target, in which case the Directors can waive or adjust the Performance Target(s) accordingly. A Performance Target cannot be adjusted
so that it is more difficult to satisfy.

 

		3.4	Assignability

personal representatives to exercise the Option following the Option Holder’s death, the Option will be personal to the Option Holder
and will not be capable of being transferred, assigned or charged.

the duly executed Agreement (including the Working Time declaration as contained in Background E of this Agreement) will be sent to the

    5

     

    

 

		4	Option limits

 

		4.1	To the extent that the grant of this Option to the Option Holder would cause the Individual Limit to be
exceeded, the number of Shares granted under this Option which exceeds the Individual Limit will form part of an Unapproved Option.

 

		5	Rights of exercise and lapse of option

 

		5.1	The Option may only be exercised in the circumstances referred to in clauses 5 and 1, subject to the remainder
of this clause. Any such exercise must be in accordance with clause 6.

 

		5.2	Leaver

 

In the event that the Option Holder
becomes a Leaver, the Option will lapse with immediate effect without ever becoming exercisable unless the Directors, in their absolute
discretion determine otherwise.

 

		5.3	Exercise on Exit

 

Subject to the remainder of clause 5,
in the event of an Exit other than a Takeover, the Option Holder may exercise the Option in full (regardless of the extent to which any
Performance Targets have been satisfied).

 

Subject to the remainder of clause 5,
in the event of a Takeover which results in the new beneficial owner having shares carrying more than 99% of the voting rights of the
Company, the Option Holder may exercise the Option in full (regardless of the extent to which any Performance Targets have been satisfied).

 

The Directors will determine:

 

		5.3.1	the period within which the Option may be exercised at the end of which it will cease to be exercisable
and shall not be capable of becoming exercisable again as a result of any provision of this Agreement; and

 

		5.3.2	the date or time on which the Option will lapse.

 

		5.4	Exercise before or conditional on Exit

 

Subject to clause 5.7 and notwithstanding
clause 5.3, the Directors may also determine that the Option may be exercised immediately before, or conditional upon, an Exit but otherwise
on the basis set out in this Agreement.

 

		5.5	Acceptance of Takeover

 

If the Option becomes exercisable in
connection with a Takeover, it shall be a condition of exercise (unless the Directors determine otherwise) that the Option Holder agrees
to:

 

		5.5.1	accept the terms of the Takeover and sell the Shares acquired from the exercise of the Option pursuant
to the Takeover, and

 

		5.5.2	execute a power of attorney (in such terms as the Directors shall determine, acting reasonably) appointing
any one or more of the Directors (or such other person or persons as the Directors shall determine) as the Option Holder’s attorney
to take all such actions as are necessary to effect the exercise of the Option and sale of the resulting Shares pursuant to the Takeover.

 

    6

     

    

 

		5.6	Acquisition of Control by an employee ownership trust

 

Notwithstanding the remainder of this
clause 5, in the event that the Directors anticipate that Control of the Company will be acquired by the trustee of an employee ownership
trust that complies with sections 236H to 236U of the Taxation of Chargeable Gains Act 1992, the Directors may, in their absolute discretion,
determine that such acquisition will not cause the Option to become exercisable and that clause 5.3 shall therefore not apply.

 

		5.7	Exchange Offer

 

If following a Takeover the Company
will be a subsidiary of a holding company where that holding company has substantially the same shareholders (with substantially the same
proportionate shareholdings) as the Company immediately before the Takeover, the Option shall not, unless the Directors determine otherwise,
become exercisable pursuant to clauses 5.3 to 5.4 provided the Option Holder is offered the opportunity (either in accordance with clause
1 or otherwise) to release the Option in consideration of the grant of new rights over shares in the holding company which the Directors,
acting reasonably, consider equivalent to the rights under the Option (the ‘Exchange Offer’). For the avoidance of
doubt, if the Option Holder does not accept the Exchange Offer, the Option will lapse.

 

		5.8	Disqualifying Event

 

In relation to a Disqualifying Event,
other than a Disqualifying Event dealt with in clause 5.2, the Directors may determine that the Option may be exercised immediately before
or during the period of 90 days (or such other period as they in their absolute discretion determine) following the Disqualifying Event.
Where the Directors determine that the Option may be exercised they will also determine the extent to which it can be exercised and the
period within which it can be exercised and, in doing so, may take into account the extent to which any Performance Targets have been
satisfied at the time of the Disqualifying Event.

 

		5.9	Notifications to Option Holder

 

The Directors shall notify the Option
Holder as soon as practicable following any determination(s) made pursuant to this clause 5.

The Option shall lapse on the occurrence

		5.10.2	the date on which the Option Holder becomes a Leaver;

 

		5.10.3	the expiry of any applicable period determined in accordance with clause 5.8 (Disqualifying Events);

 

		5.10.4	unless the Directors determine otherwise, the date or time determined in accordance with clause 5.3.2;

 

		5.10.5	the expiry of the period within which the Exchange Offer is stated to remain open for acceptance assuming
the offer referred to in clause 5.7 has not been validly accepted;

the Option Holder is deprived of the legal or beneficial ownership of the Option;

 

		5.10.8	12 months after the date of death of the Option Holder; and

 

		5.10.9	any other date determined in accordance with this Agreement.

		6.1	The Option will be exercisable in whole or in part by notice in writing (in the form prescribed by the
Company from time to time) given by the Option Holder (or the personal representatives of the Option Holder) to the Company. The notice
of exercise of the Option will be accompanied by a remittance in cleared funds for the aggregate of the Exercise Price payable and any
Tax Liability unless the Company has agreed an alternative arrangement. The effective date of exercise will be the date on which the Company
is satisfied that all necessary documentation and information has been provided and that all conditions have been satisfied.

 

		6.2	Subject to clause 7, within 30 days of the exercise of the Option, the Directors will allot or procure
the transfer of the Shares in respect of which the Option has been validly exercised and will issue a definitive certificate in respect
of the Shares allotted or transferred, unless the Directors consider that such allotment or transfer would not be lawful in the relevant
jurisdiction. Shares so allotted or transferred will be held subject to the Company's articles of association from time to time.

 

		6.3	Circumstances in which exercise will not be permitted

 

Notwithstanding any other provision
in this Agreement, the exercise of the Option (in whole or in part) will not be permitted unless the Directors are satisfied at the relevant
time that all conditions relating to such exercise pursuant to this Agreement have been met and (if then applicable) that such exercise
would not be in breach of any applicable laws, codes or regulations relating to the acquisition of securities, or any internal code of
the Company.

 

		7	The Option Holder’s undertakings

 

		7.1	The Option Holder unconditionally and irrevocably agrees as a condition of the Option Holder’s right
to exercise the Option that to the extent lawful and unless the Directors determine otherwise:

 

		7.1.1	there may be recovered from the Option Holder an amount equal to any liability to Employer’s NICs
which arises as a consequence of or in connection with the Option;

 

		7.1.2	the Option Holder will enter into any election or agreement required by the Directors (including, but
without limitation, a joint election of the type referred to in paragraph 3B of Schedule 1 to the Social Security Contributions and Benefits

of the Option is transferred to the Option Holder;

 

		7.1.3	the Option Holder will place the Group in funds and indemnify the Group in respect of the Tax Liability;

price which it can reasonably obtain such number of Shares transferred or allotted to the Option Holder following exercise as will provide
an amount equal to the Tax Liability and/or an amount equal to the Tax Liability may be withheld from any amounts due to the Option Holder
from the Group;

 

    8

     

    

 

		7.1.5	the exercise of the Option will be conditional on the Option Holder executing a tax election under section
431(1) of ITEPA to disapply fully the provisions of Chapter 2 of Part 7 of ITEPA in respect of restricted securities in such
form as is approved by or agreed with HMRC under the terms of section 431(5) of ITEPA; and

provision.

 

		8	Variation of share capital

 

		8.1	If a Variation occurs, the number or nominal value of Shares comprised in the Option and/or the Exercise
Price may be adjusted in such manner as the Directors may deem appropriate (including retrospective adjustment where a Variation occurs
after the date of exercise of the Option but the record date relating to such Variation precedes such date of exercise), provided always
that no material increase will be made to the aggregate Exercise Price in respect of the Option. Notice of any such adjustments to the
terms of the Option will be given in writing to the Option Holder by the Directors.

 

		8.2	Any adjustment made to the Exercise Price granted over unissued Shares which would have the effect of
reducing the Exercise Price to less than the nominal value of a Share will only be made if and to the extent that the Directors are authorised
to capitalise from the reserves of the Company a sum equal to the amount by which the aggregate nominal value of the Shares in respect
of which the Option is exercisable exceeds the adjusted aggregate Exercise Price. The Directors may apply such sum in paying up such shortfall
on such Shares so that on the exercise of the Option, the Directors will capitalise such sum and apply the same in paying up such amount.

Shares pursuant to the exercise of the Holdco Call Option.

		12.2	Notwithstanding any other provision of this Agreement, the grant of the Option will not form part of the
Option Holder's entitlement to remuneration or benefits pursuant to the Option Holder’s employment contract nor does the existence
of an employment contract give the Option Holder any right or entitlement to have the Option granted to the Option Holder or any expectation
that the Option will or might be granted to the Option Holder. The rights and obligations of the Option Holder under the terms of the
employment contract will not be affected by the grant of the Option. The Option Holder will not be entitled to any compensation or damages
for any loss or potential loss which the Option Holder may suffer by reason of being or becoming unable to exercise the Option in consequence
of the termination of the Option Holder’s employment contract for any reason or for any other reason which may cause the Option
to lapse (including, without limitation, any breach of contract) or in any other circumstances whatsoever. The benefit of this provision
is given for the Company, for itself and as trustee and agent of all of its subsidiaries and associated companies. The Company will hold
the benefit of this provision on trust for all of them and may assign the benefit of this provision to any of them.

 

		12.3	The Option Holder hereby acknowledges that the Company is under no obligation to ensure that a Disqualifying
Event does not occur. Furthermore, the Option Holder agrees that she shall have no claim against the Company arising in relation to the
change in the tax treatment of the Option Holder in respect of the EMI Option following a Disqualifying Event occurring. Although the
Company intends this Option to rank as an EMI Option, no warranty is given by the Company that this Option does in fact qualify as an
EMI Option nor that it will continue to do so.

Any notice or other communication in connection with this
Agreement to be given to the Company shall be delivered or sent by post to its registered office or by any other written means which the
Company and the Option Holder use to communicate with each other and which the Company shall prescribe, and in all cases shall be effective

to which documents are to be sent.
