To the Shareholders

Dear Sir or Madam

PROPOSALS RELATING TO GENERAL MANDATES TO ISSUE SHARES AND TO REPURCHASE SHARES, RE-ELECTION AND ELECTION OF DIRECTORS, AND NOTICE OF 2010 AGM

INTRODUCTION

The purpose of this circular is to seek your approval of the proposals to (i) grant general mandates to issue Shares and to repurchase Shares to the Board; and (ii) re-elect or elect (as the case may be) the retiring Directors, and to provide you with information in connection with such proposals. Shareholders’ approval on such proposals will be sought at the 2010 AGM.

GENERAL MANDATES TO ISSUE SHARES AND TO REPURCHASE SHARES

Similar to the AGM of the Bank held on 6 May 2009, ordinary resolutions will be proposed at the 2010 AGM to grant general mandates to the Board (i) to repurchase Shares on the Stock Exchange of up to 10% of the aggregate nominal amount of the issued share capital of the Bank as at the date of passing the resolution, and (ii) to allot, issue and otherwise deal with additional Shares up to a limit equal to, where the additional Shares are to be allotted wholly for cash, 5% and, in any other case, 20% of the aggregate nominal amount of the issued share capital of the Bank as at the date of passing the resolution. The purpose of the general mandate to issue Shares is to enable the Board to issue additional Shares should the need arise (for example, in

— 2 — the context of a transaction which has to be completed speedily). The Board considers it a good corporate governance practice for the Bank to impose a limit of 5% where additional Shares are allotted wholly for cash. The 20% limit to the general mandate to issue additional Shares is imposed pursuant to the Listing Rules. No Shares have been repurchased and no Shares have been allotted, issued or otherwise dealt with pursuant to the general mandates granted by the Shareholders at the last AGM. The Board has no present intention to exercise the general mandates to issue additional Shares or to repurchase Shares.

As at the Latest Practicable Date, the issued share capital of the Bank comprised 1,911,842,736 Shares. On the basis that no further Shares are issued and/or repurchased by the Bank between 22 March 2010 and the date of the 2010 AGM, the Bank would be allowed under the general mandate to issue Shares to allot and issue up to 382,368,547 Shares representing 20% of the aggregate nominal amount of the issued share capital of the Bank as at the date of the 2010 AGM.

Under the terms of the Companies Ordinance and the Listing Rules, the general mandates granted to the Board at 2009 AGM will lapse upon the conclusion of the forthcoming 2010 AGM, unless renewed at the Meeting. The Board takes the view that it would be in the interests of the Bank and the Shareholders if the general mandates were renewed. In this connection, resolutions will be proposed to renew these mandates and the explanatory statement giving certain information regarding the repurchase resolution as required under the Listing Rules is set out in Appendix I to this circular.

RE-ELECTION AND ELECTION OF DIRECTORS

At the 2010 AGM, Dr John C C Chan, Dr Eric K C Li and Dr Vincent H S Lo will retire as Directors by rotation and, being eligible, offer themselves for re-election by the Shareholders in accordance with Articles 100 to 102 of the Bank’s Articles of Association.

Further, pursuant to Article 106 of the Bank’s Articles of Association, the following Directors (who were appointed on the following dates and whose terms of office will expire at the conclusion of the 2010 AGM) will retire and, being eligible, offer themselves for election by the Shareholders at the 2010 AGM:

Name Date of appointment Mrs Dorothy K Y P Sit 7 August 2009 Mr William W Leung 7 August 2009 Mr Iain J Mackay 1 September 2009

Particulars of the above mentioned Directors offering for re-election or election (as the case may be) at the 2010 AGM are set out in Appendix II to this circular.

POLL VOTING AT THE 2010 AGM

Pursuant to Rule 13.39(4) of the Listing Rules, all resolutions set out in the notice of the 2010 AGM will be decided by poll at the 2010 AGM. The Chairman of the Meeting will demand a poll on each of the resolutions in accordance with Article 63 of the Bank’s Articles of Association.

Article 69 of the Bank’s Articles of Association provides that on a poll, every Shareholder present in person or by proxy shall have one vote for every Share held by that Shareholder. An explanation of the detailed procedures of conducting a poll will be provided to the Shareholders at the 2010 AGM.

— 3 — ACTION TO BE TAKEN

A notice of the 2010 AGM is set out on pages 12 to 14 of this circular. At the 2010 AGM, the following ordinary resolutions, among others, will be proposed for consideration and approval by Shareholders to:

(a) grant to the Board a general mandate to allot, issue and deal with additional Shares up to 20% of the aggregate nominal amount of the issued share capital of the Bank as at the date of passing the resolution provided that the additional Shares to be allotted by the Board pursuant to this mandate wholly for cash shall not in aggregate exceed 5% of the aggregate nominal amount of the issued share capital; and

(b) grant to the Board the Repurchase Mandate.

Enclosed with the Annual Report and audited financial statements for the year ended 31 December 2009 of the Bank is a Form of Proxy for use at the 2010 AGM. Whether or not you intend to attend the 2010 AGM, you are requested to complete the Form of Proxy and return it to the Bank’s Registrars, Computershare Hong Kong Investor Services Limited, 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong as instructed as soon as possible and in any event not later than 3:30 pm on 12 May 2010 or not less than 48 hours before the time appointed for holding any adjourned meeting (as the case may be). The return of a Form of Proxy will not preclude a Shareholder from attending and voting in person at the 2010 AGM.

RECOMMENDATION

The Board believes that the proposed general mandate to issue Shares and the Repurchase Mandate, and re-election and election of Directors are in the best interests of the Bank as well as its Shareholders. Accordingly, the Board recommends that all Shareholders of the Bank vote in favour of the resolutions to be proposed at the 2010 AGM.

Yours faithfully

Raymond K F Ch’ien Chairman

— 4 — APPENDIX I EXPLANATORY STATEMENT ON REPURCHASE MANDATE

This Appendix serves as an explanatory statement, as required by the Listing Rules, and also a memorandum of the terms of a proposed repurchase, as required by section 49BA(3)(b) of the Companies Ordinance, to provide information to Shareholders with regard to the Repurchase Mandate.

1. SHARE CAPITAL

As at the Latest Practicable Date, the issued share capital of the Bank comprised 1,911,842,736 Shares. Subject to the passing of the necessary ordinary resolution and on the basis that no further Shares are issued or repurchased prior to the 2010 AGM, exercise in full of the Repurchase Mandate could accordingly result in up to 191,184,273 Shares being repurchased by the Bank from the date of the 2010 AGM until the next AGM of the Bank to be held in 2011.

2. REASONS FOR REPURCHASES

The Board believes that it is in the best interests of the Bank and its Shareholders to have a general authority from Shareholders to enable the Board to repurchase Shares in the market. Such repurchases may, depending on market conditions and funding arrangements at the time, lead to an enhancement of the net asset value of the Bank and/or net assets per Share and/or earnings per Share and will only be made when the Board believes that such repurchases will benefit the Bank and its Shareholders.

3. FUNDING OF REPURCHASES

Repurchases of Shares will be funded entirely from the Bank’s available cash flow or working capital facilities, and will, in any event, be made out of funds legally available for the repurchase in accordance with the Memorandum and Articles of Association of the Bank and the applicable laws of Hong Kong.

The Board does not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Bank or the gearing levels which, in the opinion of the Board, are from time to time appropriate for the Bank. However, there might be a material adverse effect on the working capital requirements or gearing levels of the Bank (as compared with the position disclosed in the audited financial statements contained in the Annual Report for the year ended 31 December 2009) in the event that the Repurchase Mandate is exercised in full at any time.

4. GENERAL

None of the Directors, nor, to the best of their knowledge having made all reasonable enquiries, any of their associates, has any present intention to sell any Shares to the Bank if the Repurchase Mandate is approved by Shareholders.

The Board has undertaken to the Stock Exchange that (so far as the same may be applicable) it will only exercise the Repurchase Mandate in accordance with the Listing Rules and the applicable laws of Hong Kong.

— 5 — APPENDIX I EXPLANATORY STATEMENT ON REPURCHASE MANDATE

The Board is not aware of any consequences which could arise under the Takeovers Code as a consequence of any repurchases pursuant to the Repurchase Mandate. As at the Latest Practicable Date, HSBC beneficially owned Shares representing approximately 62.14% of the issued share capital of the Bank. If the Board was to exercise the Repurchase Mandate in full, the percentage shareholding of HSBC would be increased to approximately 69.05% of the issued share capital of the Bank. Such an increase would not give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code.

No purchase has been made by the Bank of its Shares in the six months prior to the Latest Practicable Date (whether on the Stock Exchange or otherwise).

HSBC, the immediate holding company of the Bank, has undertaken not to sell any Shares to the Bank under the Repurchase Mandate if the Repurchase Mandate is approved by Shareholders and exercised by the Board. Save as aforesaid, no connected person (as defined in the Listing Rules) has notified the Bank that he or she has a present intention to sell Shares to the Bank, or has undertaken not to sell any Shares to the Bank, if the Repurchase Mandate is approved by Shareholders.

5. SHARE PRICES

The highest and lowest prices at which the Shares have traded on the Stock Exchange during each of the previous 12 months were as follows:

Highest Lowest HK$ HK$

March 2009 84.70 67.00 April 2009 90.90 77.25 May 2009 111.80 86.75 June 2009 119.00 104.00 July 2009 127.00 104.00 August 2009 125.70 109.50 September 2009 116.30 108.10 October 2009 113.90 109.30 November 2009 118.00 109.70 December 2009 117.00 111.00 January 2010 116.00 108.50 February 2010 114.70 107.10 1 to 22 March 2010 115.20 107.60

The current amounts of Directors’ fees have been determined with reference to market rates, directors’ workload and required commitment. A Director will also receive a fee for duties assigned to and services provided by him as Chairman or member of various Committees of the Bank. The current amounts of the above fees have been determined with reference to the remuneration policy of the Bank. 6 Commencing from 1 January 2008, no Directors’ fees will be paid to those Directors who are full time employees of the Bank or its subsidiaries. The salary packages of such Directors have been determined with reference to the remuneration policy of the Bank.
