 (a)
    
    I agree to indemnify and keep indemnified the Company and the Company as trustee for
and on behalf of any related corporation, in respect of any liability or obligation of the
Company and/or any related corporation to account for income tax (under PAYE) or any other
taxation provisions and primary class 1 National Insurance Contributions (NICs) in the

cancellation or any other disposal of my option or arising out of the acquisition,

    The Company shall not be obliged to allot and issue any Shares or any interest in

the Company, sufficient to indemnify the Company in full against any liability the Company
has to account to the Inland Revenue for any amount of, or representing, income tax and/or
primary NICs (the Tax Liability), or I have made such other arrangement as in the opinion
of the Company will ensure that the full amount of any Tax Liability will be recovered from
me within such period as the Company may then determine.(c)
    
    In the absence of any such other arrangement being made, the Company shall have the
right to retain out of the aggregate number of shares to which I would be otherwise
entitled upon the exercise of my option, such number of Shares as, in the opinion of the
Company, will enable the Company to sell as agent for me (at the best price which can
reasonably expect to be obtained at the time of the sale) and to pay over to the Company
sufficient monies out of the net proceeds of sale, after deduction of all fees, commissions
and expenses incurred in relation to such sale, to satisfy my liability under such
indemnity.

1 to the Social Security Contributions and Benefits Act 1992) which has been approved by the
Inland Revenue (the Joint Election), for the transfer of the whole or any liability of the
Secondary Contributor to Employers Class 1 NICs to me. I realize and agree that if the Company
does not have an effective Joint Election on file for me by

to the Inland Revenue for the Liability, the Participant and the Employer agree that,
upon receipt of the funds to meet the Liability from the Employee, that such funds to

to ratify and confirm whatever the Company and the Employer may lawfully do as his
attorney. In particular, the Employer and/or the Company will have the right to enter
into such an arrangement (as envisaged by clause 3.1(c)) on the Participants behalf to
sell sufficient of the Shares issued or transferred to the Participant on the exercise

from any failure on its part after it has collected any monies from the Participant to
pass the Liability to the Collector of Taxes within the said 14 days period.
 3.4
    
    If the Participant has failed to pay all or part of the Liability to the Employer
within the 14 day period the Participant hereby indemnifies the Employer against such
