Introduction

We have examined the proposal dated 31 October 2005 for the merger between Shell Petroleum N.V. (acquiring company), The Hague, and N.V. Koninklijke Nederlandsche Petroleum Maatschappij (disappearing company), The Hague.

This proposal is the responsibility of the companies’ management. Our responsibility is to express an opinion on the merger proposal as referred to in section 2:328 subsection 1 of the Netherlands Civil Code.

1.

the share exchange ratio as set out in the merger proposal, as referred to in section 2:326 of the Netherlands Civil Code, is reasonable;

2.

the shareholders’ equity of N.V. Koninklijk Nederlandsche Petroleum Maatschappij at 30 September 2005, on the basis of valuation methods generally accepted in the Netherlands at least corresponds to the nominal paid-up amount on the aggregate number of shares to be acquired by its shareholders under the merger, increased by the cash payments (including loan notes) to which they are entitled according to the exchange ratio.
