<p style="background:white;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">I
am writing to summarise the pension arrangements in place for you. In our
letter dated 22 April&nbsp;2005, the Company had agreed to pay contributions on
your behalf to the Aon UK Pension Scheme or to a personal pension plan (PPP) of
your choice. The Company contribution payable was a flat amount of &#163;125,000 per
annum. You are not required to contribute. Alternatively, you had the option of
taking all of Aon&#146;s contributions as a non-pensionable cash supplement net of
basic rate tax and employee and employer National Insurance Contributions.</font></p>

<p style="background:white;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Due
to the limits on what could be paid (in accordance with UK pensions legislation
at that time) to either the Aon UK Pension Scheme or to a PPP up to 5 April&nbsp;2006,
<font style="letter-spacing:-.05pt;">&#163;26,400 was paid to an AXA PPP (based on
the advice given to you by Will Aitken of </font>Aon Consulting) in the
2005/2006 tax year. Contributions exceeding this amount were held by Aon to be
paid after 5 April&nbsp;2006, (as new Pensions legislation came into force in
the UK from 6 April&nbsp;2006), subject to the Annual Allowance (&#163;215,000 for
the 2006/2007 tax year).</font></p>

<p style="background:white;margin:0in 32.9pt .0001pt 7.9pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
US rules&nbsp;on pension contributions are less favourable than the UK and
limits are imposed that mean that pension contributions can become taxable in
the US if over <font style="letter-spacing:-.05pt;">certain limits. Our
understanding is that you were assigned to the US on 1<sup>st</sup> July&nbsp;2006
and that your assignment will end on 30<sup>th</sup> June&nbsp;2009. &#163;23,605
was paid to your AXA </font>PPP in the 2006/2007 tax year. Contributions
exceeding this amount were held by Aon to be paid after your assignment ends on
your return to the UK.</font></p>

pension contribution payment schedule that would apply for the period 1 January&nbsp;2007
to 6 April&nbsp;2012. With effect from the 20 September&nbsp;2007, it is
necessary to vary the payment schedule to reflect the change in Company
contribution to 25% of your salary. Using your current &#163;550,000 salary from 20 September&nbsp;2007
and updating the US IRS limit, the following revised schedule applies.</font></p>

<p style="background:white;margin:0in 0in .0001pt 1.9pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition, if your assignment to the US IRS limits is extended beyond
the three-year period or different Annual Allowances are announced for the tax
years from 2011/2012 onwards, Aon will agree with you a revised payment
schedule if required. Furthermore, a review will be undertaken in 2010 in order
that your benefits (including any retained benefits) can be checked against the
Lifetime Allowance (which will be &#163;1,800,000 in the 2010/2011 tax year) - a
revised payment schedule <font style="letter-spacing:-.05pt;">may also then be
required or it may be appropriate to cease contributions.</font></font></p>

let me know.</font></p>
