European Union Transparency Obligations Directive

The proposed European Union Transparency Obligations Directive (the “Directive”) may be implemented in a manner which could be burdensome for companies such as us. In particular, we may be required to prepare financial statements in accordance with accounting standards other than U.S. GAAP. We are under no obligation to maintain the listing of the notes, and prospective purchasers of notes should be aware that, in circumstances where a listing of the notes by the UK Listing Authority would require preparation of financial statements in accordance with standards other than U.S. GAAP, or in any other circumstances where the Directive is implemented in a manner that, in our opinion, is burdensome, the notes may be de-listed. In such a case of de-listing, we may, but are not obliged to, seek an alternative listing for the notes on a stock exchange outside the European Union. However, if such an alternative listing is not available or is, in our opinion, burdensome, an alternative listing for the notes may not be considered. Although no assurance is made as to the liquidity of the notes as a result of listing by the UK Listing Authority, de-listing the notes may have a material effect on a noteholder’s ability to resell the notes in the secondary market.
