Item 5.    Other Events

The Registrant hereby incorporates by reference the information contained in Exhibit 28 hereto in response to this Item 5.

On December 9, 2002, UAL Corp., along with certain of its subsidiaries including United Air Lines, filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code. Approximately 38% of the Principal Receivables in First Chicago Master Trust II as of the end of the November 2002 Due Period arise in accounts which are part of a co-branded program with United Airlines whereby cardholders earn air mileage awards related to the amounts charged to such accounts. Bank One cannot predict what effect, if any, the bankruptcy filing may have on the United Airline mileage award program, the co-branded program with Bank One or the benefits available under the air mileage awards. Additionally, Bank One cannot predict what effect, if any, the bankruptcy filing may have on cardholder usage of these co-branded accounts or on the payment rate related to such accounts.
