5 repurchase of the RBSG Preference Shares and certain other preference shares issued by RBSG as well as for certain related amendments to RBSG s articles of association (which relate to the pricing restrictions explained in further detail below) at a general meeting of the shareholders of RBSG, which is expected to take place on or about 28 April A Circular to shareholders of RBSG containing a notice of the General Meeting and proposing the relevant resolutions will be despatched in due course. Holders of the Relevant Securities will also be sent notice of the General Meeting and will be eligible to vote at the General Meeting on the Amendment Resolution relating to their respective class of Relevant Securities. The terms of the Relevant Securities (as set out in RBSG s articles of association) contain a pricing restriction which places a ceiling on the purchase price which RBSG may pay for the Relevant Securities. As the Purchase Prices of the Relevant Securities may exceed this ceiling, approval of the holders of the Relevant Securities will be sought to amend RBSG s articles of association to remove the pricing restriction. Separate meetings of the holders of each class of the Relevant Securities will be convened to seek approval of such class to the variation of rights attaching to such Relevant Securities. Notices of such class meetings, which are expected to take place on or about 28 April 2010, will be included in the Circular. Any acceptance for repurchase by RBSG or NatWest of Offer Securities validly tendered in an Offer is subject to the passing of the RBSG Repurchase Resolution. In addition, any acceptance for repurchase by RBSG of the Relevant Securities of any class validly tendered in an Offer is subject to the approval of the relevant Amendment Resolution and the relevant Class Resolution relating to such class of Relevant Securities. Neither RBSG nor NatWest may waive the requirement for the passing of the RBSG Repurchase Resolution and the approval of the relevant Amendment Resolutions and the relevant Class Resolutions. In relation to the Relevant Securities, it is a condition of acceptance by RBSG of tenders that a valid instruction in favour of the relevant Amendment Resolution and relevant Class Resolution is received from holders tendering Relevant Securities prior to the Expiration Deadline. Submission of a Tender Instruction will be deemed to constitute a valid instruction to the relevant Nominee to vote in favour of such resolutions in respect of the Relevant Securities included in the Tender Instruction. See Part V Further Information and Terms and Conditions of the Tender Offer of this Tender Offer Memorandum. The Nominees shall determine, in their absolute discretion, who they shall instruct to vote in respect of each validly submitted Tender Instruction.

General This Tender Offer Memorandum does not constitute an offer to buy or the solicitation of an offer to sell Offer Securities, and tenders of Offer Securities in the Offers will not be accepted from Offer Security Holders in any circumstances in which such offer or solicitation is unlawful. In those jurisdictions where the securities, blue sky or other laws require an Offer to be made by a licensed broker or dealer and a Dealer Manager or any of its affiliates is such a licensed broker or dealer in such jurisdictions, such Offer shall be deemed to be made by such Dealer Manager or such affiliate (as the case may be) on behalf of the relevant Offeror(s) in such jurisdictions.

Any tender of Offer Securities for purchase pursuant to the Offers from an Offer Security Holder that is unable to make these representations will not be accepted. Each of the Offerors, the Managers, the Tender Agents and the Registrar reserves the right, in their absolute discretion, to investigate, in relation to any tender of Offer Securities for purchase pursuant to the Offers, whether any such representation given by an Offer Security Holder is correct and, if such investigation is undertaken and as a result the relevant Offeror determines (for any reason) that such representation is not correct, such tender shall not be accepted. 7

20 PART V FURTHER INFORMATION AND TERMS AND CONDITIONS OF THE OFFERS 1. Rationale for the Offers The Offers aim to generate core tier 1 capital for the Group and to further strengthen the quality of its capital base. If completed, the Offers would generate a profit for the Group, and thereby increase the Group s core tier 1 capital. In the past, the Group focused principally on the Group s overall tier 1 ratio, but over the last two years investors and regulators have placed increasing emphasis on core tier 1 capital, which they see as having greater capacity to absorb losses in stressed conditions. The Group s strategic targets now centre on the core tier 1 ratio, and by further strengthening this ratio, the Offers will further enhance the Group s capital base. The Offers will also give effect to certain undertakings made by the Group in December 2009 to Her Majesty s Treasury and the European Commission to improve the Group s regulatory capital position. RBSG and NatWest have also announced on the date of this Tender Offer Memorandum invitations to holders of certain other securities issued by RBSG, NatWest and certain trust issuers to purchase such securities for cash, on the terms and subject to the conditions set out in the Offer to Purchase pertaining thereto of the same date as this Tender Offer Memorandum. RBS has also announced on the date of this Tender Offer Memorandum invitations to holders of certain other securities issued by RBSG, The Royal Bank of Scotland plc and NatWest to offer to exchange such securities for new senior debt securities of RBS. 2. Cancellation Offer Securities other than the Capital Trust Securities and the Argon Notes purchased pursuant to the Offers will be cancelled and will not be held or reissued or resold. In relation to the Capital Trust Securities, the Capital Trust Securities repurchased by RBSG will need to be held by RBSG for an indefinite period, as the underlying securities cannot be unwound to the extent the Capital Trust Securities are repurchased absent amendments to underlying documents. In relation to the Argon Notes acquired by RBSG under the relevant Offer, RBSG intends to deliver or procure the delivery of any such Argon Notes acquired by RBSG under the relevant Offer to Argon. Pursuant to a conditional repurchase agreement, in exchange Argon will tender a number of Argon Preference Shares to RBSG, calculated as a proportion of the total number of Argon Preference Shares, such proportion being the same as the proportion which the Argon Notes purchased by RBSG under the relevant Offer bears to the total outstanding Argon Notes. The consideration for the delivery by RBSG of the Argon Notes to Argon will be equal to the consideration payable by RBSG in relation to the Argon Notes under the relevant Offers, and the consideration for the delivery by Argon of the Argon Preference Shares to RBSG will be equal to the consideration payable by Argon to RBSG for the delivery by RBSG of the Argon Notes to Argon. Consequently no cash will be payable by either RBSG or Argon. RBSG will cancel any such Argon Preference Shares so acquired by it from Argon. 3. Total amount payable to Offer Security Holders If an Offeror decides to accept valid tenders of Offer Securities pursuant to an Offer, the total amount that will be paid to each Offer Security Holder on the Settlement Date for the Offer Securities of such Offer Security Holder accepted for purchase will be an amount (rounded to the nearest e0.01, U.S.$0.01, CAD0.01 or 0.01, as the case may be, with half a cent/penny rounded upwards) equal to the sum of: (a) the Purchase Price for such Offer Securities; and (b) the Accrued Distribution on such Offer Securities. 4. Aggregate Offer Limit After the Expiration Deadline, if the Offerors accept valid tenders of Offer Securities pursuant to the Offers, the Offerors will accept such valid tenders in accordance with the Acceptance Priority as set out in Part XI Acceptance Priority of this Tender Offer Memorandum. The Offerors will announce whether they have decided to accept valid tenders of Offer Securities pursuant to all or any of the Offers as soon as reasonably practicable after the conclusion of the General Meeting and Class Meetings. 18
