Item 5.  Other Events:

added to its portfolio credit card receivables in a group of 391,082 accounts,
with a total outstanding principal amount of $ 926,484,993.68. The total
outstanding principal amount of receivables in the trust portfolio after the
August 1, 2003 addition was $ 33,243,540,908.80. The management of Chase

portfolio is being filed as Exhibit 10.1 to this current report on Form 8-K.
