Adjustment of Exchange Price

The Preference Shares will be delivered to International Power plc following the issue of such Preference Shares to the Bondholder, in consideration for which International Power plc will deliver such number of Shares as results from dividing the paid up value of each Preference Share (translated into pounds sterling at the fixed exchange rate of US$1.5893 = £1) by the Exchange Price in effect on the Conversion Date (rounded down to the nearest whole number of Shares).

Clause 7 of the Preference Share Guarantee and Undertaking requires an adjustment to be made to the Exchange Price in accordance with the terms of the schedule thereto on the occurrence of certain corporate events. As a result of the announcement by International Power plc that it will pay a cash Dividend to the Shareholders, an adjustment to the Exchange Price is required pursuant to paragraph B(iii) of the schedule.  

The current Exchange Price is 157 pence.

From and including 29 October 2009, being the date of payment of the cash Dividend, the Exchange Price will be adjusted to 154 pence. All other Terms and Conditions of the Bonds remain unchanged.
