THE FOLLOWING IS A MESSAGE GIVEN TO STAFF OF THE ROYAL DUTCH/SHELL GROUP OF COMPANIES
ON OCTOBER 28, 2004.

Message to Staff

Not for release, publication or distribution in whole or in part into Canada or Japan.

Today we have announced a proposal to establish Royal Dutch Shell as a unified group – with one board, one chief executive and one headquarters. This is a major step that will change how we work.

As I said at our strategy presentation last month, we will make Shell a different company – less complicated, more competitive and more focused on delivering performance and results.

We must do this if we are to regain our competitive position and the trust of our shareholders.

I am honoured to be the first Group Chief Executive. This starts immediately. I am accountable for implementing our strategy and delivering success.

I am supported by a strong team of Executive Directors:

We are committed to driving the company forward – building on the improvements we have already started in the businesses and our drive for an Enterprise First culture.

Having a single headquarters in The Hague will improve communications and reduce management duplication. Some of the Corporate Centre functions now carried out in London will move there, after the normal consultation with those affected and with appropriate employee representative bodies. We will still have a major presence in London, where Downstream and Trading will continue to be based.

The establishment of Royal Dutch Shell plc – which will be a UK registered company – will depend on shareholder resolutions at the AGMs in April and other conditions. We hope to have the new structure in place in May.

Many of you are shareholders and will want to know how this would affect your holdings. You can find more details of the proposals on www.shell.com/investor.

I am very excited by this decisive step and the opportunities it opens. It will help us to work together more efficiently and effectively around the world, with quicker decision-making and clearer lines of communication.

We also announced our Q3 results today. These are satisfactory results, and I am pleased with the progress we’re making. I am of course disappointed that the more rigorous review and audit process we have put in place has identified potential proved reserves reductions.

Royal Dutch Shell has many strengths – its assets, its technologies, its global portfolio and – most importantly – you, its people. I believe that together we can harness and extend those strengths to beat the competition and meet the expectations of our shareholders.

I look forward to doing this with you.

Best wishes

Jeroen van der Veer
