                        MasterCard International Reports
                    Continued Growth In First Quarter of 2004

           All Regions Achieve Double Digit Growth in Purchase Volume
                        For Both Credit and Offline Debit

Purchase, NY, May 3, 2004 - MasterCard International today announced strong
performance results for the first three months of 2004, demonstrating continued
growth across almost all regions and in key measures of success in the payments
industry. Reflecting improving global economic activity, total purchases on
MasterCard credit and debit cards rose 13.6% in the first quarter, with each
region reporting double-digit growth.

"The year is getting off to a strong start for both MasterCard and our
customers," said Robert W. Selander, MasterCard President and CEO. "We have seen
an increase in worldwide purchase growth in every region, reflecting the
improving global economy. Compared to the same period in 2003, all regions of
MasterCard experienced double-digit growth in purchases, including Asia/Pacific,
which is turning around after a challenging year in 2003."

Performance highlights for the first three months of 2004, in addition to
purchase volume, include:

o    Cardholders across the globe used MasterCard-branded cards (excluding
     Maestro(R) and Cirrus(R)) for over 3.7 billion transactions, generating
     gross dollar volume (GDV) of $331.9 billion, an increase of 8.4% over the
     same period in 2003. GDV includes both purchase and cash volume;

o    MasterCard's almost 25,000 customer financial institutions around the world
     had issued more than 627.5 million MasterCard-branded cards, a 6.6%
     increase over first quarter 2003.

MasterCard's strong growth in the first three months of 2004 was fueled by
growth in both credit and debit programs. GDV for worldwide credit and charge
programs grew 8.9% to $270.1 billion, and GDV for offline debit programs rose
6.7% to $61.7 billion over the same period in 2003. Gross transactions for
credit and offline debit programs increased by 10% in 2004 compared to the first
quarter in 2003.

Currently, cardholders can use their MasterCard cards at more than 22 million
locations around the world. Acceptance locations include merchant locations,
ATMs and other locations where cash may be obtained.

Significant Milestones Achieved

MasterCard also achieved a wide range of significant business milestones in the
first quarter:

o    Diners Club, a part of Citigroup, and MasterCard International announced
     that they are pursuing an alliance to provide enhanced acceptance to Diners
     Club cardholders. Diners Club cards that are issued in the United States
     and Canada will be reissued with the MasterCard brand on the front of the
     card in order to function as MasterCard cards. These cards will be accepted
     at the over 22 million locations around the world that accept MasterCard
     credit cards. Diners Club cards issued by Diners Club International
     franchises (outside the United States and Canada) will include the
     MasterCard brand on the back of the card, allowing these cards to be
     accepted at MasterCard merchants in the U.S. and Canada;

o    MasterCard and ABN AMRO Bank N.V. signed a multi-year strategic alliance
     under which MasterCard will be the bank's preferred payment card brand in
     more than 60 countries. MasterCard will work with ABN AMRO to develop their
     existing payment card business and will support their entry into new
     markets;

o    MasterCard Advisors' acquisition of Tower Group, the leading research and
     advisory firm focused on the global financial services industry,
     significantly strengthened our independent advisory research unit, Purchase
     Street Research. MasterCard Advisors is a global professional services
     organization, offering consulting, research, outsourcing and information
     products and services.

o    British Airways became the first global airline to offer MasterCard(R)
     SecureCode(TM) across multiple regions, with a roll-out to 23 country
