TAXATION IN NORWAY

1. General

The following summary of certain tax issues that may arise as a result of holding Collateralised Currency Securities is based on the Norwegian tax legislation in force as of the date of this Supplementary Prospectus and is intended only as general information for holders of securities who are resident or domiciled in Norway for tax purposes. The summary does not purport to cover all aspects of Norwegian law that may be of relevance for the Norwegian holders of Collateralised Currency Securities, nor does it cover the specific rules where Collateralised Currency Securities are held by a partnership or are held as current assets in a business operation. Special tax consequences that are not described below also may apply for certain categories of taxpayers, including investment companies, mutual funds and persons who are not resident or domiciled in Norway. Furthermore, Norwegian tax legislation may to some extent be amended with retroactive effect. It is recommended that prospective applicants for Collateralised Currency Securities consult their own tax advisors for information with respect to the special tax consequences that may arise as a result of holding Collateralised Currency Securities, including the applicability and effect of foreign income tax rules, provisions contained in double taxation treaties and other rules which may be applicable.

2. Taxation on realisation Holders of Collateralised Currency Securities who are Norwegian resident corporations or individuals, and who sell or redeem their Collateralised Currency Securities are subject to capital gains taxation in Norway. Correspondingly, losses may be deducted.

The tax liability applies irrespective of how long the Collateralised Currency Securities have been owned and the number of Collateralised Currency Securities realised or redeemed. Gains are taxable as general income in the year of realisation, and losses can be deducted from income from other sources in the year of realisation. The tax rate of general income is currently 28 per cent.

The capital gain or loss is calculated per Collateralised Currency Security and equals the remuneration received in respect of the Collateralised Currency Security less the purchase price and acquisition and realisation costs for the Collateralised Currency Security.

Income taxes or capital gains taxes payable in other jurisdictions, by Norwegian Security Holders, or withholding tax payable on redemption amounts in respect of the Collateralised Currency Securities, may be deductible against Norwegian tax payable on the same income. The deduction is limited, however, to the corresponding amount of Norwegian tax applicable. The right for both Norwegian and other jurisdictions to tax Security Holders directly or through the application of withholding taxes may be limited by applicable tax treaty.

3. Withholding tax No deduction or withholding for or on account of Norwegian tax is required to be made on payments from the Issuer to the Security Holders on Redemption of Collateralised Currency Securities.

4. Net Wealth Tax Corporate holders are not subject to net wealth taxation in Norway.

Individual holders are subject to net wealth taxation in Norway. For any year, the value of the Collateralised Currency Securities on 1 January in the next year will form part of the taxable base of a holder for the purpose of the net wealth taxation. The maximum aggregated rate of net wealth tax is currently 1.1 per cent.

5. Stamp duty There is currently no stamp duty or other charges in Norway on the purchase, sale or realisation of Collateralised Currency Securities.

6. Inheritance tax When Collateralised Currency Securities are transferred either through inheritance or as a gift, such transfer may give rise to inheritance or gift tax in Norway if the decedent, at the time of death, or the donor, at the time of the gift, is a resident or citizen of Norway, or if the Collateralised Currency Securities are effectively connected with a business carried out through a permanent establishment in Norway.

7. VAT Transactions regarding Collateralised Currency Securities are exempt from Norwegian value added tax.
