[APPENDIX]
Joint Election under s431 ITEPA 2003 for full or partial disapplication of
Chapter 2 Income Tax (Earnings and Pensions) Act 2003

One Part Election

1.
Between

the Employee                         _________________
whose National Insurance Number is         _________________
and
the Company (who is the Employee's employer)     _________________
of Company Registration Number            _________________

2.
Purpose of Election

This joint election is made pursuant to section 431(1) or 431(2) Income Tax
(Earnings and Pensions) Act 2003 (ITEPA) and applies where employment-related
securities, which are restricted securities by reason of section 423 ITEPA, are
acquired.

The effect of an election under section 431(1) is that, for the relevant Income
Tax and NIC purposes, the employment-related securities and their market value
will be treated as if they were not restricted securities and that sections 425
to 430 ITEPA do not apply. An election under section 431(2) will ignore one or
more of the restrictions in computing the charge on acquisition. Additional
Income Tax will be payable (with PAYE and NIC where the securities are Readily
Convertible Assets).

--------------------------------------------------------------------------------

Should the value of the securities fall following the acquisition, it is
possible that Income Tax/NIC that would have arisen because of any future
chargeable event (in the absence of an election) would have been less than the
Income Tax/NIC due by reason of this election. Should this be the case, there is
no Income Tax/NIC relief available under Part 7 of ITEPA 2003; nor is it
available if the securities acquired are subsequently transferred, forfeited or
revert to the original owner.

--------------------------------------------------------------------------------

3.
Application

This joint election is made not later than 14 days after the date of acquisition
of the securities by the employee and applies to:
