Item 5. Other Events
--------------------

On July 3, 2003, the Arizona Corporation Commission (ACC) approved the planned
acquisition by UniSource Energy of the Arizona gas and electric assets from
Citizens Communications, Inc. (Citizens) and the Settlement Agreement (Citizens
Settlement Agreement), subject to certain terms and requirements.

The acquisition is expected to occur on or about July 28, 2003. The acquisition
has not yet been approved by the Securities and Exchange Commission.

The Citizens Settlement Agreement was described in UniSource Energy's and Tucson
Electric Power Company's (TEP) Form 8-K dated April 1, 2003, and filed as an
exhibit thereto. The order approved the acquisition on the terms of the Citizens
Settlement Agreement, with the following amendments:

     1)   UniSource Energy shall commence renegotiation of the existing
          purchased power agreement with Pinnacle West Capital Corporation, and
          90% of any savings associated with the renegotiated contract shall be
          allocated to ratepayers and 10% to shareholders (changed from a 60/40
          allocation).

     2)   A general rate case for UniSource Energy's proposed electric and gas
          operating company subsidiaries shall not be filed for a period of at
          least three years and the resulting rate increase shall not be become
          effective prior to August 1, 2007.

     3)   Within 120 days of the effective date of the decision, UniSource
          Energy shall file a plan to open the electric service territories to
          retail competition by December 31, 2003.
