                      BANCA NAZIONALE DEL LAVORO ARGENTINA
                                        
HSBC has signed an agreement with Banca Nazionale del Lavoro SpA to acquire the
latter's banking operations in Argentina, Banca Nazionale del Lavoro S.A. (BNL),
for a consideration of US$155 million, to be met from internal resources within 
Argentina.

HSBC Bank Argentina SA has 58 branches throughout the country providing a full
range of banking and financial products and services, including commercial,
consumer and corporate banking, to over 512,000 customers.

BNL started operating in Argentina in 1960 and currently has 91 branches in 18
provinces, 700,000 active personal customers and 26,700 commercial customers,
mainly retail and small and medium-sized businesses.

Simon Martin, CEO and President of HSBC Argentina, said: "This acquisition will
allow HSBC to increase its distribution network and market presence in
Argentina. The size and reach of our combined operations will help us bring
economies of scale to delivering a wide range of products and services to
existing and prospective customers and so contribute to the profitable
development of the financial sector in Argentina."

The transaction is subject to regulatory approval and is expected to be
completed in the first quarter of 2006. After completion, and also subject to
regulatory approval, Banca Nazionale del Lavoro Argentina's operations will be
merged into HSBC Bank Argentina.
