Item 2.03  Creation of a Direct Financial Obligation or an Obligation under an
           Off-Balance Sheet Arrangement of a Registrant

NICOR COMPLETES $900 MILLION SYNDICATED REVOLVING CREDIT FACILITIES

Nicor Inc. announced on Thursday, September 2, 2004 the establishment of two
syndicated revolving credit facilities totaling $900 million to replace an
existing syndicated revolver of $500 million that expires in September 2004 and
a $500 million seasonal revolver that expired in March 2004. The new facilities
consist of a $500 million, 3-year revolver available to Nicor Inc. and Nicor
Gas, the company's gas distribution business, and a $400 million, 210-day
seasonal revolver, expiring in April 2005, available to Nicor Gas. These new
facilities, which serve as backup for the issuance of commercial paper,
accommodate the company's short-term borrowing needs primarily associated with
purchasing natural gas and with supporting storage inventory for delivery to its
customers during the winter.

The credit facilities were arranged by ABN AMRO and JP Morgan Chase and include
a total of 21 lenders.
