Dear Senior Staff Savings Fund Participant:

Important Notice Concerning Your Rights Under the Senior Staff Savings Fund
Blackout Notice


As previously communicated in the letter dated June 1, 2005, the proposed unification (the “Transaction”) of Royal Dutch Petroleum Company (“Royal Dutch”) and The “Shell” Transport and Trading Company, p.l.c. (“Shell Transport”) under a single parent company, Royal Dutch Shell plc, has been announced. As part of the Transaction, Royal Dutch Shell plc is making an offer to acquire all of the issued and outstanding shares of Royal Dutch stock.

The Transaction will affect the Senior Staff Savings Fund because the Senior Staff Savings Fund includes the Royal Dutch Stock Fund as one of the investment options available to participants. As you are aware, any investment balance you may hold in the Senior Staff Savings Fund, including the Royal Dutch Stock Fund, represents a bookkeeping entry that measures Shell  Oil Company’s obligation to you. Holdings represented in the Senior Staff Savings Fund are hypothetical and neither you nor the Senior Staff Savings Fund hold actual balances in the
Royal Dutch Stock Fund.

Subject to the approval of the Transaction, your balance (if any) in the existing Royal Dutch Stock Fund will automatically be exchanged for an equivalent number of units in the new Royal Dutch Shell Stock Fund. (You do not need to take any action for this to occur.)

Only the Royal Dutch Stock Fund within the Senior Staff Savings Fund will be affected. Your other investment options in the Senior Staff Savings Fund will not be affected by the Blackout Period.

IMPORTANT INFORMATION
In order to synchronize the handling of the Senior Staff Savings Fund with the handling of the Shell Savings Plans and to ensure that all information is transferred accurately from the Royal Dutch Stock Fund to the Royal Dutch Shell Stock Fund, there will be a period of time when you will be unable to process transactions in the Royal Dutch Stock Fund. This time period, during which you are unable to exercise your rights otherwise available under the plan, is called a “Blackout Period” and is expected to begin during the week of July 10, 2005, and is expected to end during the week of July 17, 2005. During these weeks, you can determine whether the Blackout Period has started or ended by calling the Shell Benefits Service Center 1-800-30 SHELL (1-800-307-4355) and speaking with a Service Representative. The specific Blackout Period dates will be posted on Fidelity NetBenefits® at http://netbenefits.fidelity.com as soon as they are available. The dates will be located in the News section on the right-hand side of the Home Page. The Blackout Period will only affect the Royal Dutch Stock Fund within the
 

 
 Senior Staff Savings Fund. Your other investment options in the Senior Staff Savings Fund will not be affected by the Blackout Period.

Whether or not you are planning retirement in the near future, we encourage you to carefully consider how the Blackout Period may affect your retirement planning, as well as your overall financial planning.

During the Blackout Period, you will be unable to direct or diversify assets held in your Royal Dutch Stock Fund account. For this reason, it is very important that you review and consider the appropriateness of your current investments in the Royal Dutch Stock Fund in light of your inability to direct or diversify those investments during the Blackout Period. For your long-term retirement security, you should give careful consideration to the importance of a well-balanced and diversified investment portfolio, taking into account all your assets, income and investments. You should be aware that there is a risk to holding substantial portions of your assets in the securities of any one company, as individual securities tend to have wider price swings, up and down, in short periods of time, than investments in diversified funds. Individual stock funds, like the Royal Dutch Stock Fund, are more likely to have wide price swings over a short time frame than mutual funds. Therefore, you might have a large loss during the Blackout Period and you would not be able to direct the sale of the Royal Dutch Stock Fund from your account during the Blackout Period. You have the flexibility to help minimize market risk by transferring a portion or all of your account balance in the Royal Dutch Stock Fund to a more conservative investment option, such as the Thrift Fund, prior to the beginning of the Blackout Period.

What Royal Dutch Stock Fund activities will be affected during the Blackout Period?
·  
Exchanges - You will be unable to exchange any portion of your balance in the Royal Dutch Stock Fund to another investment option once the Blackout Period begins. You also will not be able to exchange any balance into the Royal Dutch Stock Fund from another investment option once the Blackout Period begins.
·  
Account Distributions - Your ability to take account distributions during the Blackout Period will be reduced by the amount of your account invested in the Royal Dutch Stock Fund. All other investment options, except the Royal Dutch Stock Fund, will be available for distributions during the Blackout Period. Should you request a total distribution during the Blackout Period, only that portion of your account not invested in the Royal Dutch Stock Fund will be distributed to you. Once the Blackout Period is over, you will have to request a separate distribution of the Royal Dutch Shell Stock Fund to complete a total distribution of your account.

What will happen to contributions during the Blackout Period?
·  
Any contributions will continue to be directed to the Royal Dutch Stock Fund during
the Blackout Period. They will be invested in the cash portion of the Royal Dutch Stock Fund, which may have an impact on the performance of the Royal Dutch Stock Fund during the Blackout Period.

When can activities resume?
·  
Subject to the approval of the Transaction, it is anticipated that the Royal Dutch Shell Stock Fund will open for normal activity during the week of July 17, 2005. Any extension of the period needed to approve the Transaction may extend the Blackout Period. You will receive additional information should an extension be necessary.
 

 

 
The investment objective of the Royal Dutch Shell Stock Fund will remain essentially the same - to replicate the investment return of the Royal Dutch Shell Stock Fund in the Shell Savings Plans, which is to be invested primarily in the stock of Shell Oil Company’s parent company, Royal Dutch Shell plc.
