  Waiver of Listing Rules to enable HSBC Holdings plc to hold Treasury Shares

On 19 December 2005, the Stock Exchange granted a conditional waiver to the
Company in respect of Rule 10.06(5) of the Listing Rules to allow it,
following any repurchase of shares, to elect to hold its own shares in
treasury as opposed to automatically having to cancel those shares. As a
consequence of the waiver the Stock Exchange has agreed certain
modifications to other Listing Rules applicable to the Company.
Shares held in treasury may subsequently be sold for cash, transferred
pursuant to an employees' share scheme or cancelled. This option is
available to the Company under changes introduced in UK law.
The waiver is subject to certain conditions, including compliance by the
Company with applicable law and regulation in the United Kingdom in relation
to the holding of shares in treasury. As part of the waiver, the Company has
agreed with the Stock Exchange a set of Modifications to the Listing Rules
necessary to enable the Company to hold treasury shares. The Modifications
also reflect various consequential matters to deal with the fact that the
Company may hold treasury shares in the future. A full version of the
Modifications is posted on the Company's website at www.hsbc.com and on the
Stock Exchange's website at www.hkex.com.hk and copies of the Modifications
are available on request from the Group Company Secretary, 8 Canada Square,
London E14 5HQ and the Corporation Secretary, The Hongkong and Shanghai
Banking Corporation Limited, 1 Queen's Road Central, Hong Kong.
The waiver was granted and the consequential Modifications agreed with the
Stock Exchange on the basis of, amongst other things, the specific
circumstances of the Company as a company incorporated in England with a
listing on the London Stock Exchange which, as a result, has the ability
under UK law to hold any shares it repurchases in treasury.
Background

On 19 December 2005, the Stock Exchange granted a conditional waiver to the
Company in respect of Rule 10.06(5) of the Listing Rules to allow it to hold its
own shares in treasury. As a consequence of the waiver the Stock Exchange has
agreed certain modifications to other Listing Rules applicable to the Company.
As the Company is incorporated in England it is governed by applicable company
law in the United Kingdom. Such law enables companies with a listing on the
London Stock Exchange to hold their own shares in treasury following a share
repurchase subject to certain conditions. The Company has a dual primary listing
in Hong Kong and London. Following the changes to the law in the United Kingdom,
the UKLA introduced changes to the UK Listing Rules to permit the holding of
shares in treasury. In view of its primary listing in Hong Kong, the Company
requested the Stock Exchange to grant a waiver in respect of Rule 10.06(5) of
the Listing Rules, in addition to making certain consequential modifications to
the other Listing Rules applicable to the Company, in order to enable it to make
use of the flexibility, as a company incorporated in England, to repurchase its
own shares and to hold them in treasury. The waiver is intended to put the
Company in the same position in relation to treasury shares as other public
companies in the United Kingdom whose shares are admitted to the official list
of the Financial Services Authority. The Stock Exchange has agreed to grant the
waiver and has agreed to the consequential Modifications, on the basis of,
amongst other things, the specific circumstances of the Company.

Authority to hold Treasury Shares

Treasury shares are a company's own issued shares which it has repurchased but
not cancelled. Pursuant to the Companies Act 1985 (as amended), the Company is
permitted (with the approval of shareholders) to retain and hold in treasury any
shares it repurchases up to a maximum of 10 per cent of its issued share capital
from time to time. The Company obtained the authority of its shareholders at its
Annual General Meeting held on 27 May 2005 to hold treasury shares subject to
the approval of the Stock Exchange and other regulatory authorities in Hong
Kong, which has now been obtained. Accordingly, the Company may now utilise this
authority to acquire its own shares and hold them in treasury, and subsequently
to sell or transfer such shares in satisfaction of the exercise of options
under, or otherwise pursuant to, any of the Company's existing employees' share
schemes. The existing repurchase authority granted by shareholders will expire
at the Annual General Meeting on 26 May 2006 (at which meeting approval will be
sought from shareholders to renew this authority).

Regulatory Controls

Pursuant to the Companies Act 1985 (as amended) a company incorporated in
England that holds treasury shares is only entitled to (i) sell such treasury
shares for cash, (ii) transfer such treasury shares for the purposes of, or
pursuant to, an employees' share scheme, or (iii) cancel such treasury shares.
Any sale of treasury shares for cash will be subject to the pre-emption rights
of the existing holders of that class of shares (other than the company by
virtue of it holding treasury shares) except to the extent that, inter alia, (i)
the sale of such treasury shares falls within the limit of the general authority
to disapply pre-emption rights (such authority was granted by the shareholders
of the Company at its Annual General Meeting on 27 May 2005 and the Company will
seek to renew this authority at its Annual General Meeting to be held on 26 May
2006), or (ii) the company is selling treasury shares for cash to an employees'
share scheme. The UK Listing Rules require that if a company sells its treasury
shares where such shares are listed, the price at which the company sells such
shares must not be at a discount of more than 10 per cent to the middle market
quotation of those listed shares (as derived from the daily official list of the
London Stock Exchange) at the time of announcing the relevant offer or agreeing
the placing of such shares unless the sale of such treasury shares is pursuant
to a pre-existing general authority to disapply pre-emption rights or the sale
at a discount is specifically approved by the company's shareholders. If a
company cancels any of its treasury shares it must also diminish the amount of
its issued share capital by the nominal amount of the shares cancelled.

Chapter 12 of the UK Listing Rules contains certain additional regulatory
controls in respect of treasury shares which include, inter alia, the
requirement (i) not to sell for cash or transfer for the purposes of or pursuant
to an employees' share scheme any treasury shares during a prohibited period
(within the meaning of the UK Listing Rules) other than in certain limited
circumstances provided for in the UK Listing Rules, and (ii) to make a
notification to a regulatory information service for dissemination to the UK
market if (a) by virtue of it holding treasury shares, a company is allotted
bonus shares (as described below) and (b) a company sells for cash, transfers
for the purposes of, or pursuant to, an employees' share scheme or cancels any
treasury shares it holds. When a company makes any repurchases of its shares it
must also state in its notification relating to the repurchase the number of
shares which will be or have been cancelled and the number of shares which will
be or are held in treasury following any such repurchase. In accordance with its
obligations under the Listing Rules the Company will make equivalent
notifications to the Stock Exchange. In addition, the Company must disclose in
its annual report and accounts sales of treasury shares for cash made otherwise
than through the market, or in connection with an employees' share scheme, or
otherwise than pursuant to an opportunity which was made available to all
holders of the Company's listed shares on the same terms.

Rights Attaching to Treasury Shares

Shares held in treasury by a company incorporated in England remain part of such
company's existing issued share capital. However, a company cannot exercise any
right in respect of the treasury shares it holds; in particular, it does not
have any right to attend and vote at meetings of the company, nor does it have a
right to any dividend or other distribution of the company's assets in respect
of the treasury shares it holds. However, in the event of a capitalisation issue
by the company, it is entitled to receive fully paid bonus shares in respect of
the treasury shares it holds which it can elect either to cancel or to hold in
treasury after their allotment provided that the aggregate nominal value of the
shares held in treasury, from time to time, does not exceed 10 per cent of the
nominal value of the company's total issued share capital (including its
treasury shares).

Description of Modifications

As part of the waiver, the Company has agreed with the Stock Exchange a set of
Modifications to the Listing Rules necessary to enable the Company to hold
treasury shares. The Modifications also reflect various consequential matters to
deal with the fact that the Company may hold treasury shares in the future. In
particular, Rule 10.06(5) of the Listing Rules is modified so that the
requirement for the automatic cancellation of the listing of all shares which
are purchased by an issuer will not apply to listed shares purchased by the
Company and held as treasury shares. Shares purchased by the Company and held as
treasury shares will remain listed and the listing will not be suspended or
cancelled. Any subsequent sale of such treasury shares or transfer of such
treasury shares pursuant to an employees' share scheme will not, for the
purposes of the Listing Rules, constitute a new issue of shares and will not
require a new listing application to be made.

The general mandate granted to the Directors on 27 May 2005 (which the Company
will seek to renew at the Annual General Meeting to be held on 26 May 2006) to
allot shares also applies to the sale of shares out of treasury for cash. The
Company will make an announcement pursuant to Rule 13.28 if it agrees to sell
treasury shares for cash (other than in connection with an employees' share
scheme) in the same manner as the announcement that would be required for a new
issue of shares for cash.

As stated above, the Company will make the same notifications to the Stock
Exchange that it makes to the UK market in relation to any repurchase of shares
to be held in treasury, and in relation to a sale and/or transfer of treasury
shares, including notifications required to be made pursuant to Chapter 12 of
the UK Listing Rules (as described in the paragraph headed "Regulatory Controls"
above). The Company will make certain additional disclosures in relation to any
shares repurchased and held in treasury in the explanatory statement seeking
shareholder approval of the repurchase mandate and in the Company's annual
report and accounts.

For the purposes of the connected transaction rules contained in Chapter 14A of
the Listing Rules, any sale of treasury shares will generally be treated in the
same manner as the issue of new securities. In relation to employees' share
schemes, the provisions of Chapter 17 of the Listing Rules are modified to
enable treasury shares to be used to satisfy the exercise of options under, or
otherwise in connection with, the Company's employees' share schemes.

Generally, Listing Rules which contain a calculation by reference to the
Company's issued share capital have been modified in so far as they apply to the
Company so that any shares which the Company holds in treasury from time to time
are excluded for the purposes of such calculation. In addition, the definition
of market capitalisation in the Listing Rules has been modified so that for the
purposes of calculating the market capitalisation of the Company pursuant to the
relevant Listing Rule any treasury shares held by the Company are excluded from
such calculation. As a consequence of these modifications, the relevant size
tests used for the purposes of Chapters 14 and 14A have been modified so that
(i) the consideration ratio calculated in accordance with Rule 14.07(4), which
refers to a listed issuer's total market capitalisation, will exclude any
treasury shares the Company holds for the purposes of calculating its total
market capitalisation, and (ii) the equity capital ratio calculated in
accordance with Rule 14.07(5), which refers to a listed issuer's issued equity
capital before the relevant transaction, will exclude any treasury shares the
Company holds from its issued equity capital.

In addition, for the purposes of calculating the number of shares in the hands
of the public pursuant to Rule 8.08, any treasury shares held by the Company
will not be taken into consideration, with the effect that at least 25 per cent
of the Company's issued share capital (excluding any treasury shares held by the
Company) must be in public hands.

The modifications described above are a summary of only the key modifications
made under the waiver. In addition, there are various consequential
modifications to the Listing Rules which have been agreed between the Company
and the Stock Exchange as sensible modifications in order to accommodate the
holding by the Company of treasury shares. The full Modifications are posted on
the Company's website at www.hsbc.com and on the Stock Exchange's website at
www.hkex.com.hk and copies of the Modifications are available on request from
the Group Company Secretary, 8 Canada Square, London E14 5HQ and the Corporation
Secretary, The Hongkong and Shanghai Banking Corporation Limited, 1 Queen's Road
Central, Hong Kong.

Impact of Treasury Shares on Shareholders

The obligation on a shareholder to disclose an interest held in a company's
shares in accordance with the provisions of Part XV the Securities and Futures
Ordinance of Hong Kong (Cap 571) ("SFO") will not be affected by virtue of the
Company holding shares in treasury. Shares held by the Company in treasury
remain part of its issued share capital, therefore, if the Company repurchases
shares and holds such shares in treasury rather than cancelling them it will not
reduce the Company's issued share capital for the purposes of section 314 of the
SFO. On this basis, a shareholder's interest in the issued share capital of the
Company will not change (except to the extent that such shareholder's own shares
have been repurchased by the Company).

Terms of the Waiver

The waiver is subject to certain conditions under which the Company will:

(a) comply with the Companies Act 1985 (as amended) and the UK Listing Rules in
relation to treasury shares and inform the Stock Exchange as soon as practicable
in the event of any failure to comply or any waiver from these requirements
being granted;

(b) inform the Stock Exchange promptly in the event of any material change being
made to the UK regime in relation to treasury shares;

(c) make an announcement on the grant of the waiver;

(d) confirm compliance with the conditions in the Company's annual report,
annual review and with the Notice to Shareholders of any meeting at which a
resolution to authorise the holding of treasury shares is to be considered; and

(e) in the event of changes to the Hong Kong regulatory regime and the Listing
Rules, comply with the relevant changes in relation to treasury shares.

In accordance with the terms of the waiver, the Company will make an annual
submission to the Stock Exchange in respect of any changes to the Listing Rules
which may take place from time to time to assess whether they have any
implications for its ability to hold treasury shares. In addition, should any
further consequential modifications be required as a result of such changes to
the Listing Rules, the Modifications shall be amended accordingly and a full
version of the amended Modifications will be posted on the Company's website at
www.hsbc.com and on the Stock Exchange's website at www.hkex.com.hk and copies
of the amended Modifications will be available on request.
