ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On November 23, 2004, MasterCard Incorporated, MasterCard International
Incorporated, the principal operating subsidiary of MasterCard Incorporated, and
UMB Bank & Trust, N.A., as indenture trustee for the 7.36% Series A Senior
Secured Notes (the "notes"), amended the terms of MasterCard International's
guarantee in connection with the notes by transferring certain obligations from
MasterCard International to MasterCard Incorporated. The notes were issued in
August 1999 by MasterCard International O'Fallon 1999 Trust, a consolidated
variable interest entity, to finance MasterCard's global technology and
operations facility in O'Fallon Missouri. As a result of the amendment to the
guarantee, MasterCard Incorporated has become a party to the guarantee and has
assumed certain covenant compliance obligations, including financial reporting
and maintenance of consolidated net worth. The amendment to the guarantee aligns
MasterCard's financial reporting and net worth covenant obligations under the
guarantee with similar obligations under its other debt instruments. MasterCard
entered into the amendment to the guarantee to better reflect MasterCard's
corporate structure and to reduce the costs and administrative burden of
complying with different debt covenants.
