QUESTIONS & ANSWERS RELATING TO
RESTRUCTURING

DEFINITIONS

Defined terms used in this document have the meaning ascribed to them in the press release dated 28 October 2004 which for ease of reference are set out below:

2

QUESTIONS & ANSWERS

1.

Who is Royal Dutch? Who is ST&T?

		The Group has two parent companies Royal Dutch and ST&T.
		Royal Dutch is the 60 per cent owner of the Group. It is a Dutch company with a wide public share ownership.
		ST&T is the 40 per cent owner of the Group. It is an English company with a wide public share ownership.
2.		What will be the name of the new company?
		Royal Dutch Shell plc.
3.		As a shareholder, do I need to take any action now?
		No action is required at this stage. In due course a document will be issued to shareholders explaining fully the details of the proposals, the conditions to be satisfied and the steps you should take. It is expected that this detailed document will be issued in March 2005.
4.		Will I receive shares in the new company?
		Yes, if the Transaction is completed, in return for your existing holding of Royal Dutch or ST&T shares you will be offered shares in Royal Dutch Shell plc.
5.		How many shares will I receive?
		The terms of the proposed Transaction will provide that Royal Dutch shareholders will be offered 60 per cent of the issued ordinary shares in Royal Dutch Shell plc and ST&T shareholders will be offered 40 per cent of the issued ordinary shares in Royal Dutch Shell plc. There are currently 2,074,400,000 Royal Dutch ordinary shares and 9,624,900,000 ST&T ordinary shares in issue and therefore the exchange terms are expected to be that:

	•		Royal Dutch ordinary shareholders will be offered two ‘A’ shares in Royal Dutch Shell plc for every one Royal Dutch share currently owned; and
	•		ST&T ordinary shareholders will be offered approximately 0.2874 ‘B’ shares in Royal Dutch Shell plc for every one ST&T share currently owned.

3

6.		Are these exchange ratios rounded? Will I get full value for my shares? What will happen to the fractions?
		The exchange ratio for shares in Royal Dutch has not been rounded. In the case of ST&T this figure has been rounded for the purposes of the press release. In calculating your share allocations we will use precise ratios such that Royal Dutch shareholders will be offered 60 per cent. of the issued ordinary shares in Royal Dutch Shell plc and ST&T shareholders will be offered 40 per cent. Details of the treatment of fractional entitlements of ST&T shareholders will be contained in documents expected to be sent to shareholders in March 2005.
7.		Is the new company British or Dutch?
		The Group will remain global in nature with operations in over 140 countries worldwide. The new parent company, Royal Dutch Shell plc, will be incorporated in the United Kingdom and will have a Dutch headquarters and tax residency. It will have its shares listed in London, Amsterdam and, in the form of ADRs, in New York.
8.		When will I get to vote on these proposals?
		It is expected that these proposals will be put to shareholders at meetings held immediately after Royal Dutch and ST&T’s AGMs on 22 April 2005. In advance of those meetings documents will be issued to shareholders explaining the proposals fully and also explaining what action you should take. It is expected these documents will be issued in March 2005.
9.		You say that further details of the Tender Offer and the Scheme of Arrangement will be announced in due course.
		Full details of the Royal Dutch Tender Offer and the ST&T Scheme will be detailed in the shareholder documents that are expected to be issued in March 2005. These documents will explain the action that shareholders should take in connection with the proposals. If you are in any doubt as to the course of action you should take you should obtain independent financial advice.
10.		Why are you issuing two types of shares, ‘A’ shares and ‘B’ shares, if the whole idea is to form one new company out of Royal Dutch and ST&T? What is the difference between ‘A’ shares and ‘B’ shares?
		The proposals involve a move from two parent companies (Royal Dutch and ST&T) to a single parent (Royal Dutch Shell plc) where all shareholders have identical economic and voting rights whether they hold ‘A’ or ‘B’ shares. However, in seeking to preserve the current tax treatment of dividends for all shareholders, Royal Dutch Shell plc will have ‘A’ and ‘B’ shares. It is envisaged that Royal Dutch shareholders will receive the ‘A’ shares and Dutch-sourced dividends while ST&T shareholders will receive the ‘B’ shares and UK-sourced dividends. The ‘A’ and ‘B’ shares will otherwise be identical and will vote together as a single class on all matters and have the same dividends declared.

4

11.		What is the difference in the tax treatment of A and B shares
		We are not in a position to give tax advice to shareholders. All we can say is that the holders of ‘A’ shares will receive Dutch-sourced dividends and the holders of B shares are expected to receive UK-sourced dividends. If you are in any doubt as to the treatment of dividends received on the ‘A’ or ‘B’ shares you should contact an independent financial or tax adviser.
12.		Can I choose whether I have ‘A’ shares or ‘B’ shares?
		No. All existing ST&T shareholders will be offered ‘B’ shares and all existing Royal Dutch shareholders will be offered ‘A’ shares.
13.		When will I receive my new shares?
		You will receive your new shares when the proposed Transaction has been approved and implemented. This is expected to be in May 2005.
14.		When will I receive my new share certificate?
		To the extent that share certificates in Royal Dutch Shell plc are sent out, you will receive your new certificate shortly after completion of the proposed Transaction in May 2005. Full details of how settlement of your new shares will occur will be contained in the documentation expected to be issued to shareholders in March 2005.
15.		At a later date can I swap my ‘B’ shares with ‘A’ shares?
		At a later date you will be able to trade ‘A’ shares and ‘B’ shares in the market, but Royal Dutch Shell plc will not be able to offer a swapping facility.
16.		At a later date can I buy both ‘A’ shares and ‘B’ shares?
		Yes, you may buy or sell either ‘A’ or ‘B’ shares. Both ‘A’ and ‘B’ shares will be listed in London Stock Exchange and Euronext Amsterdam Exchange as well as the New York Stock Exchange (in ADR form).
17.		Will the ‘A’ shares and ‘B’ shares be listed on the stock exchanges separately? What stock exchanges will the new company be listed on?
		The ‘A’ shares and the ‘B’ shares will both be listed on the London and Euronext Amsterdam stock exchanges and, in ADR form, on the New York stock exchange. They will be separately quoted. It is expected that there will be substantial liquidity in the shares on both London and Euronext.

5

18.		Are the ‘A’ and ‘B’ shares fungible/interchangeable?
		No, the shares are not fungible/interchangeable. Although they are not interchangeable, they have identical economic and voting rights and the ‘A’ shares will receive Dutch-sourced dividends which are paid in Euros and the ‘B’ shares are expected to receive UK-sourced dividends paid in Pounds Sterling.
19.		Will both the ‘A’ and ‘B’ shares be traded on London and Amsterdam markets?
		Yes, both shares will trade on both markets as well as, in ADR form, in the New York.
20.		What currency will the ‘A’ and ‘B’ shares be traded in each exchange?
		Both shares will trade in Pounds Sterling on the London Stock Exchange, in Euros on the Euronext Amsterdam Exchange and US Dollars on the New York Stock Exchange.
21.		Can you outline the tax treatment of the Transaction for me? What is the capital gains tax position?
		A summary of the tax implications of the proposed Transaction for shareholders will be contained in the documents expected to be issued in March 2005. If you would like advice on the tax treatment of the proposed Transaction you should consult an independent financial or tax adviser.
22.		What will the Transaction mean for the share buyback programme? Will you have to be out of the market until the new structure is implemented?
		To date, Royal Dutch, ST&T and other Group companies have completed approximately $1.7 billion of their $2.0 billion buyback programme (including stock option hedges) announced in April 2004. Given applicable US securities laws, the buyback programme will be suspended for the time being.

6

23.		Will the dividend paid on the ‘A’ shares be the same as that paid on the ‘B’ shares?
		The cash (i.e. pre-tax) dividend declared on the ‘A’ shares and the ‘B’ shares will be identical. However the tax treatment of the dividend declared may be different depending on whether you hold ‘A’ shares or ‘B’ shares. The tax treatment varies significantly by geography and tax circumstance of the shareholder. You should, therefore, consult your own independent financial or tax adviser.
24.		Why are the new company’s dividends to be paid quarterly?
		Moving to quarterly dividend payments provides shareholders with more frequent and regular cash flow. It also brings Royal Dutch Shell plc in to line with other leading companies.
25.		If the dividends are to be paid quarterly, does this mean that the total dividend for the year will be more?
		No. Quarterly payment does not affect the total amount of dividends being paid, which will continue to be set on the basis of Royal Dutch Shell plc’s commitment to dividend increases at least in line with inflation over time. However, the move to a quarterly dividend does provide more frequent and regular cash flow.
26.		What will the new company’s dividend policy be?
		Dividends will be paid quarterly (as opposed to semi-annually currently) starting with the dividend for the first quarter of 2005. Dividends will be declared in Euros but the holders of ‘B’ shares will receive dividend payments in Pounds Sterling and holders of ADRs in US Dollars. Royal Dutch Shell plc will continue to seek to increase dividends at least in line with inflation over time.
27.		What currency will the new dividend be in?
		Royal Dutch Shell plc will declare its dividend in Euros but holders of ‘B’ shares will receive dividend payments in Pounds Sterling and holders of ADRs in US Dollars.
28.		Who will decide the currency exchange rate?
		The exchange rate will be the spot exchange rate between Euros and the currency you receive payment in at the time of declaration of the dividend.

7

29.		When will the final 2004 dividend be declared and paid? When will Royal Dutch Shell plc declare and pay its first quarterly dividend?
		The final dividend in respect of the 2004 financial year is expected to be paid by Royal Dutch and ST&T to their respective shareholders as a second interim dividend. The dividend will be announced at the time of the Group’s preliminary results announcement in February 2005 and paid in March 2005.
		The dividend in respect of the first quarter of the 2005 financial year, under the Group’s new quarterly dividend policy, is expected to be declared on or shortly after completion of the proposed Transaction, expected in May 2005, and paid within a month of declaration. It is expected that Royal Dutch Shell plc will declare this dividend.
30.		When will Royal Dutch Shell plc’s dividend payment dates be?
		Royal Dutch Shell plc is expected to declare its first dividend on or shortly after completion of the proposed Transaction, expected to be in May 2005, and paid within a month of declaration. The dates for further quarterly dividends will be announced in due course.
31.		Why will you have a second interim dividend rather than a final dividend?
		We do not need shareholder approvals to declare a second interim dividend but would need shareholder approvals for a final dividend. Accordingly, we would need to wait for the AGMs, expected to be on 22 April 2005, to declare a final dividend.
32.		Will the second interim dividend be similar in amount to your usual final dividend?
		The second interim dividend will be of a similar amount to that which the dividend would have been had it been declared as a final dividend.
33.		When will Royal Dutch Shell plc’s first AGM be?
		The first AGM of Royal Dutch Shell plc will be in 2006 — it will not have an AGM in 2005. Royal Dutch and ST&T will have separate AGMs in 2005 which are expected to be on 22 April 2005.
34.		Where will the new company’s AGM be held?
		Royal Dutch Shell plc’s annual general meetings will, in general, be held in The Netherlands. However, a video link to a UK venue will also be made available to facilitate the attendance and participation of UK-based shareholders. Full details of these arrangements have yet to be finalised and will be sent to shareholders together with their Notice of Meeting.

8

35.		What is the date of the 2005 AGM?
		The AGMs of Royal Dutch and ST&T are expected to be held on 22 April 2005. Royal Dutch Shell plc’s first AGM will be in 2006.
36.		Will I still receive a Notice of Meeting?
		Yes, if you are a registered shareholder and you have given your address to the company or to the appropriate shareholder registry. In addition, appropriate advertisements will appear in the press as is currently the case for Royal Dutch meetings.
37.		When I get my new share certificate, what should I do with my old one?
		If you have an old share certificate representing either Royal Dutch or ST&T shares, you will be asked to either destroy it or return it to the registrars as it will cease to have any monetary value. Full details of the arrangements for settlement of your shares in Royal Dutch Shell plc will be contained in the documents that are expected to be issued to you in March 2005.
38.		Who will be the new company’s registrar?
		You will be advised who the registrars of the new holding company will be in the document expected to be issued to you in March 2005.
		The registrar of Royal Dutch Shell plc, once appointed, will be responsible for maintaining the list of its shareholders. It will also be responsible for carrying out various administrative functions in connection with the relationship between Royal Dutch Shell plc and its shareholders as is normal for a UK incorporated public limited company.
39.		Will my current dividend mandate instruction be honoured?
		Yes.
40.		I am a member of the Shell Monthly Purchase Plan / Shell Dividend Re-Investment Plan / Shell Nominee Service. How does the Transaction impact on this?
		Details of how you may be affected and of the steps you should take will be set out in the document expected to be issued to you in March 2005. If you are in any doubt as to the course of action you should take you should obtain independent financial advice.

9

41.		I have a PEP/ISA. How does the Transaction impact on this?
		Details of how you may be affected and of the steps you should take will be set out in the document expected to be issued to you in March 2005. If you are in any doubt as to the course of action you should take you should obtain independent financial advice.
42.		Will my election to receive a Summary Annual Report, rather than the full version, be honoured?
		Yes, if you have previously elected to receive a Summary Annual Report, rather than the full version, this election will be honoured.
43.		Will you be offering shareholders the option to sell their shares free of charge?
		No, the Transaction does not include a free share dealing service.
44.		What will happen to my ST&T Preference shares?
		Proposals will be made by ST&T to the holders of its 5.5 per cent First Preference Shares and its 7 per cent Second Preference Shares in conjunction with the implementation of the proposed Transaction. It is the intention that such shares should be repaid and cancelled prior to implementation of the Transaction.
45.		What will happen to all the old Royal Dutch and ST&T unclaimed dividends?
		Unclaimed ST&T dividends are currently held for the collection of the person entitled to them for a period of 12 years from the date when it became due for payment. Unclaimed Royal Dutch dividends are held for a period of 6 years. These rights are unaffected by the unification of the parents and unclaimed dividends can still be collected as before.
46.		Why won’t Royal Dutch Shell plc have any bearer shares?
		Royal Dutch Shell plc will be a UK incorporated, and London Stock Exchange listed, public limited company. It is not common practice for such companies to issue bearer shares. Such a step, today, is not necessary to facilitate trading of Royal Dutch Shell plc’s shares on the Euronext Amsterdam Exchange due to the advances in trading and settlement systems.
47.		What will happen to my Royal Dutch bearer shares listed on Euronext Amsterdam?
		Your shares, which are probably in CF-form for clearing and settlement on the Euronext Amsterdam Exchange, will be exchanged for shares in Royal Dutch Shell plc if you tender your shares in the Tender Offer and the bid will be honoured. You will be asked to tender your shares via your bank or broker.

10

48.		Will both the ‘A’ shares and the ‘B’ shares have separate ADR programmes?
		Yes
49.		What will be the difference between the Class ‘A’ and Class ‘B’ ADR programmes?
		To preserve the current tax treatment of dividends for all shareholders, Royal Dutch Shell plc will have two ADR programmes, a Class ‘A’ programme and a Class ‘B’ programme. Holders of Royal Dutch’s New York registry shares will receive the Class ‘A’ ADRs and will receive Dutch-sourced dividends while ST&T ADR holders will receive the ‘B’ ADRs and, it is intended, UK-sourced dividends. These ‘A’ and ‘B’ ADRs will otherwise be identical and the shares that they represent will vote together as a single class on all matters and have the same dividends declared.
50.		What are the U.S. tax consequences related to the proposed Transaction?
		A summary of the tax consequences of the proposals will be contained in the definitive documents issued to shareholders in March 2005. If you are in any doubt as to the tax treatment of the proposed Transaction you should consult an independent financial or tax adviser.
51.		Where can holders of ST&T ADRs and holders of Royal Dutch New York registry shares get the shareholder documents related to the Transaction?
		Holders of ST&T ADRs are expected to receive shareholder documents related to the Scheme from the ADR Depositary, once these documents have been prepared and sent to the ADR Depositary.
		Holders of Royal Dutch New York registry shares are expected to receive copies of the U.S. Prospectus and related documents for the Tender Offer by mail, when these documents have been prepared.
52.		I am a holder of ST&T ADRs. How can I vote on the Scheme?
		Under the terms of the Depositary Agreement, you will vote through the Bank of New York, the ADR Depositary.

11

53.		I am a holder of Royal Dutch New York registry shares. How can I vote on the adoption of the Implementation Agreement?
		Holders of Royal Dutch New York registry shares will receive shareholder documents through JPMorgan as registrar, which will detail the procedures for voting on the Implementation Agreement.
54.		I am a holder of ST&T ADRs. What will I receive in the Scheme?
		If the Transaction is completed, holders of ST&T ADRs will receive Royal Dutch Shell plc Class ‘B’ ADRs. It is expected that one Royal Dutch Shell plc Class ‘B’ ADR will represent two Royal Dutch Shell plc ‘B’ shares. Accordingly, for every one ST&T ADR currently owned, a ST&T ADR holder will receive approximately 0.8621 new Royal Dutch Shell plc Class ‘B’ ADRs.
55.		I am a holder of Royal Dutch New York registry shares. What will I receive in the Tender Offer?
		If the Tender Offer is completed, holders of Royal Dutch New York registry shares will receive Royal Dutch Shell plc Class ‘A’ ADRs, and will have the option to elect to receive Royal Dutch Shell plc ‘A’ shares. It is expected that one Royal Dutch Shell plc Class ‘A’ ADR will represent two Royal Dutch Shell plc ‘A’ shares. Accordingly, for every one Royal Dutch New York registry share currently owned, a Royal Dutch shareholder will receive one new Royal Dutch Shell plc Class ‘A’ ADR.
56.		Will the terms of the Royal Dutch Shell ADR programmes be different to the terms of ST&T’s current ADR programme?
		The identity of the ADR depositary has not yet been identified and, accordingly, the detailed terms of the ADR programme have not been finalised. Full details will be contained in the documents to be issued to shareholders in March 2005.
57.		How many ordinary shares will each Royal Dutch Shell ADR represent?
		Each Royal Dutch Shell ADR will represent 2 ‘A’ or ‘B’ ordinary shares of Royal Dutch Shell plc. This means that a holder of one Royal Dutch ordinary share will be offered one new Royal Dutch Shell plc ADR as a result of the proposed Transaction. A holder of one ST&T ADR will be offered approximately 0.8621 new Royal Dutch Shell plc ADRs as a result of the Transaction.
58.		I am a holder of Royal Dutch New York registry shares. How can I accept the Tender Offer?
		The U.S. Prospectus and related documents for the Tender Offer will contain details on how to accept the Tender Offer. It is expected that these documents will be issued to you in March 2005.

12

59.		Will this transaction cost me anything?
		In principle there will be no direct costs to shareholders arising from the proposed Transaction.
