HSBC AGREES TO ACQUIRE MAJORITY SHAREHOLDING IN KOREA EXCHANGE BANK

THE ACQUISITION
HSBC Holdings plc ("HSBC"), through its indirect, wholly-owned subsidiary, HSBC
Asia Pacific Holdings (UK) Limited ("HSBC Asia"), has agreed to acquire 51.02
per cent of the issued share capital of Korea Exchange Bank ("KEB"), the sixth
largest bank in Korea.

The shares will be acquired from LSF-KEB Holdings SCA, a holding company owned
by Lone Star Fund IV (US) LP and Lone Star Fund IV (Bermuda) LP (collectively
"Lone Star"). The purchase price is KRW3,400 billion plus US$2,700 million
amounting in total to the equivalent of approximately US$6,317 million, payable
in cash, assuming the acquisition is completed on or before 31 January 2008.

The acquisition is subject to a number of conditions including the receipt of
applicable governmental and regulatory approvals, particularly in Korea from the
Financial Supervisory Commission ("FSC") and the Fair Trade Commission. In the
event that the acquisition is completed after 31 January 2008, the purchase
price will be increased by US$133 million, also payable in cash.

Under a shareholders' agreement with Lone Star, The Export-Import Bank of Korea
("KEXIM") is entitled to require HSBC Asia to purchase, on substantially the
same terms, part or all of its shareholding in KEB (KEXIM's entire shareholding
represents a further 6.25 per cent of the issued share capital of KEB).

HSBC does not intend to make a tender offer to KEB's remaining shareholders and,
following completion of the acquisition, KEB will remain a company listed on the
Korea Exchange (the "KRX").

HSBC Group Chairman Stephen Green said, "Our stated strategy is to focus on
expanding HSBC's presence in important growth economies, particularly in Asia,
Latin America and the Middle East and to maintain our capital strength to allow
us to take advantage of strategic opportunities. This prospective acquisition
reflects that strategy.

"It would provide HSBC with a significant presence in Asia's third largest
economy and reinforce our position as Asia's number one international bank.

"HSBC has a long history in Korea. We are delighted with this prospective
acquisition, which we believe would benefit the customers and staff of both KEB
and HSBC."

REASONS FOR AND BENEFITS OF THE TRANSACTION
HSBC is one of the world's largest banking and financial institutions with an
unparalleled international network across 83 countries and territories. The
acquisition accords with HSBC's stated strategy of targeting investment at high
growth markets with international connections and will further enhance the HSBC
Group's footprint in the Asia-Pacific region.

HSBC believes that KEB would benefit from having a long-term, and
internationally focused, strategic shareholder which would enable it to enhance
future growth prospects. KEB has particular strengths in trade finance and
foreign exchange, complementing HSBC's global capabilities in these areas. HSBC
would also offer KEB the opportunity to add to the range of services it offers
in other areas, from personal finance and credit cards to building deeper
commercial and corporate relationships.

The importance of, and role played by, KEB in Korean international business,
when linked with HSBC's broader global network, will provide the leading
platform to serve Korea's businesses and people internationally.

As a bank with a long history in Korea, and as the prospective majority
shareholder in one of the nation's largest financial institutions, HSBC intends
to make a full contribution to the further development of the financial services
industry in Korea.

KEB's listing on the KRX will provide a continuing opportunity for Korean
investors to participate in KEB's future.

FINANCIAL RATIONALE FOR TRANSACTION
It is expected that the acquisition will be accretive to HSBC's earnings per
share in its first full year of operations within the HSBC Group. HSBC has
identified a number of areas of potential business growth for KEB as a member of
the HSBC Group.

INFORMATION ON KEB
KEB has over 5.4 million deposit customers and is the sixth largest bank in
Korea, as measured by total assets at 30 June 2007. It has over 350 branches and
a presence in 18 countries, making it Korea's leading international bank.

At 30 June 2007, KEB's total assets were KRW73.5 trillion (US$78.2 billion) with
shareholders' equity of KRW6.3 trillion (US$6.7 billion). In the year ended 31
December 2006, KEB generated pre-tax profits of KRW1,482 billion (US$1,577
million) (2005: KRW1,654 billion (US$1,760 million)) and net income of KRW1,006
billion (US$1,070 million) (2005: KRW1,934 billion (US$2,058 million)). Net
income in the six months to 30 June 2007 was KRW516 billion (US$549 million).
These results were prepared in accordance with Korean GAAP.

ACQUISITION AGREEMENT
Under an agreement entered into on 3 September 2007 with Lone Star, HSBC Asia
has conditionally agreed to purchase 329,042,672 KEB shares, representing 51.02
per cent of the issued share capital of KEB, from Lone Star.

Conditions and termination right
The acquisition is conditional upon the satisfaction or waiver of certain
conditions on or before 30 April 2008 including (but not limited to):

..  KEB, HSBC Asia and other relevant members of the HSBC Group having received
   all necessary governmental and regulatory approvals, particularly in Korea
   (and none of the approvals being granted subject to any conditions having
   adverse effect).

..  No adverse effect having occurred in relation to KEB's business, assets,
   operations or liabilities that is material to the KEB Group taken as a whole
   (excluding the effects of changes in general economic, financial, political,
   regulatory or market conditions applicable to similar businesses in Korea).

..  Certain specified actions in relation to KEB not occurring without the prior
   consent of HSBC Asia.

..  No material business restriction or suspension having been imposed on KEB as
   a result of the ongoing litigation in relation to the merger of the KEB Card
   business with KEB in 2004.

Within Korea, applications for approval will be made to the Financial
Supervisory Commission and the Fair Trade Commission. In the event that the
formal application for approval has not been submitted to the FSC on or before
31 January 2008, Lone Star has the right to terminate the acquisition agreement.

Further due diligence
Under the acquisition agreement, HSBC Asia has the right to conduct further due
diligence on KEB in a period of 40 days following signing of the agreement,
which may be extended by a further seven days in certain circumstances. HSBC
Asia is then entitled, within five days of the end of that period, to notify
Lone Star that it does not wish to proceed with the acquisition in which case
the acquisition agreement will terminate.

Consideration
The consideration for the shares is KRW3,400 billion plus US$2,700 million
amounting in total to the equivalent of approximately US$6,317 million,
equivalent to KRW18,045 (US$19.20) per share, payable in cash, assuming the
acquisition is completed on or before 31 January 2008. In the event that
completion has not taken place on or before 31 January 2008, HSBC will pay a
further US$133 million, equivalent to KRW380 (US$0.40) per share. The
acquisition agreement is conditional on completion taking place on or before 30
April 2008. Settlement on closing will be made in cash in US dollars, with the
Korean won element of the consideration converted into US dollars at the then
current exchange rate.

The consideration expressed in KRW at KRW18,045 per share represents a premium
of 21.5 per cent to the share price as at 31 August 2007 of KRW14,850 per share,
a 26.8 per cent premium to the 10 day average trading price to 31 August 2007 of
KRW14,230 per share, a 29.0 per cent premium to the 30 day average trading price
to 31 August 2007 of KRW13,990 per share and a multiple of KEB's stated book
value at 30 June 2007 of 1.83 times.

The consideration payable will be offset by any dividends in respect of the
shares subject to the acquisition paid by KEB by reference to a record date
which is prior to the registration of HSBC Asia as a shareholder entitled to any
such dividend.

The consideration was arrived at after arm's length negotiations between the
parties. HSBC was advised by HSBC Corporate, Investment Banking and Markets and
UBS AG acting through its business group, UBS Investment Bank. The Directors of
HSBC believe the terms of the transaction are fair and reasonable and in the
interests of HSBC's shareholders as a whole.

The acquisition will be financed from HSBC's own resources. Following
completion, KEB will be accounted for as a subsidiary in HSBC's consolidated
financial statements.

Guarantee
HSBC Asia will have the benefit of a guarantee from Lone Star Fund IV (US) LP
and Lone Star Fund IV (Bermuda) LP guaranteeing the financial obligations of
LSF-KEB Holdings SCA under the acquisition agreement.

KEXIM
KEXIM also owns 40,314,387 shares in KEB and, under the terms on which Lone Star
originally invested in KEB, KEXIM has the right to require any purchaser of Lone
Star's shares to acquire part or all of its shares on substantially the same
terms. If this right is exercised in respect of all of KEXIM's shares, it would
involve the payment by HSBC Asia of KRW727 billion (US$774 million) to KEXIM,
assuming that completion takes place before 31 January 2008 and the
consideration is set in Korean won. If completion takes place after 31 January
2008, there will be a corresponding increase in the amount payable to KEXIM in
line with the additional payment to Lone Star. Such purchase, if KEXIM exercises
its right, would be conditional on, and completed at the same time as,
completion of the purchase of Lone Star's KEB shares.

Management and operations
Following completion and subject to relevant approvals, HSBC will be entitled to
nominate a majority of directors to the Board of KEB including KEB's Chairman
and Chief Executive and certain other officers. The KEB name will be retained
with consideration being given to the addition, in a suitable form, of
reference to KEB being a member of the HSBC Group to reflect its majority
shareholding.
