**NICOR
      Completes Syndicated Revolving Credit Facility**





Naperville,
      IL - Nicor Inc. (NYSE:GAS) today announced the establishment of a syndicated
      revolving credit facility. The new facility is a $400 million, 210-day seasonal
      revolver expiring in May 2007, available to Nicor Gas, the company’s gas
      distribution business. The new facility replaces a similar revolver that expired
      in April 2006. In addition to the newly established facility, the company has
      an
      existing $600 million, 5-year revolver available to Nicor Inc. and Nicor Gas,
      which expires in September 2010. The two facilities, totaling $1 billion, serve
      as backup for the issuance of commercial paper, accommodating the company’s
      short-term borrowing needs.





The
      new
      facility included a total of 13 lenders and was arranged by J.P. Morgan
      Securities Inc. and ABN AMRO Incorporated.





Nicor
      Inc. (NYSE: GAS) is a holding company and is a member of the Standard &
Poor’s 500 Index. Its principal businesses are Nicor Gas, one of the nation’s
      largest natural gas distribution companies, and Tropical Shipping, a
      containerized shipping business serving the Caribbean region and the Bahamas.
      Nicor also owns and has an equity interest in several energy-related businesses.
