ITEM 7.01 REGULATION FD DISCLOSURE
----------------------------------

         In November 2003, UniSource Energy entered into an acquisition
agreement that provides for the acquisition of all of UniSource Energy's 
outstanding common stock for $25.25 per share by an affiliate of Saguaro
Utility Group L.P. (Saguaro), an Arizona limited partnership whose general
partner is Sage Mountain, L.L.C. and whose limited partners include investment
funds associated with Kohlberg Kravis Roberts & Co., L.P., J.P. Morgan Partners,
LLC, and Wachovia Capital Partners.

         The acquisition still requires the approval of the Arizona Corporation
Commission (ACC).

         On November 8, 2004, an ACC administrative law judge (ALJ), appointed
by the ACC to review the acquisition, recommended that the ACC deny the
application of UniSource Energy seeking approval for the acquisition. The ALJ's
recommendation was contained in a form of opinion and order which concludes that
the acquisition is not in the public interest.

         Listed below are a series of questions and answers regarding the status
of the proposed acquisition.


Q:       What is UniSource Energy's response to the ALJ's recommendation?

A:       UniSource Energy vigorously disputes the ALJ's recommendation, which is
         not binding on the ACC. UniSource Energy believes the transaction would
         provide significant benefits for its customers and communities. The
         ACC's rules permit the filing of exceptions to the ALJ's recommendation
         and UniSource Energy intends to file exceptions.


Q:       Are the ACC Commissioners bound by the ALJ's recommendation?

A:       No. The ACC Commissioners are not bound by the ALJ's recommendation and
         may change it, deny it or accept it as written. Following the filing of
         exceptions, the ACC and its staff will set the date for an open meeting
         of the ACC to deliberate the acquisition.  The ACC will then issue its 
         own opinion and order regarding the acquisition.


Q:       How often do the ACC Commissioners make rulings opposing or modifying
         an ALJ recommendation?

A:       While it is unusual for the ACC Commissioners to reject the 
         recommendation of an ALJ, it is not unprecedented. The ACC 
         Commissioners commonly modify the provisions of recommended orders 
         prior to adopting them.


Q:       Does the proposed acquisition provide immediate benefits to UniSource
         Energy's utility customers?

A:       Yes. We believe the proposed acquisition would provide significant
         benefits to UniSource Energy's customers, communities, employees and
         shareholders. Moreover, the more than 40 conditions to the acquisition
         that UniSource Energy has agreed to in the ACC proceeding, provide
         additional assurances and verification that the benefits and
         protections built into the proposed acquisition will be realized.

Q:       What happens if the ACC requires UniSource Energy to lower its utility
         rates as a condition of the acquisition?

A:       The acquisition agreement does not provide for a reduced price to the
         UniSource Energy shareholders in the event of rate concessions. If the
         ACC imposed rate concessions, then, under the acquisition agreement,
         Saguaro could terminate the agreement and UniSource Energy would be
         obligated to reimburse up to $7 million of Saguaro's expenses.


Q:       The ALJ recommended a finding that the proposed acquisition does not 
         meet the standard of affiliated interest rule R-14-2-803c.  What 
         standard is included in that rule?

A:       Essentially, the rule says that the ACC may reject the proposal if it
         determines that the proposal would impair the financial status of the
         utility, otherwise prevent it from attracting capital at fair and
         reasonable terms, or impair the ability of the public utility to
         provide safe, reasonable and adequate service. We believe the evidence
         presented clearly demonstrates that the standard has been met.


Q:       What termination fees would UniSource Energy be required to pay if the
         ACC fails to approve the proposed acquisition?

A:       In the event that the ACC denies the acquisition, issues an order
         approving the acquisition which does not satisfy the conditions of the
         acquisition agreement or fails to approve the transaction by March 31,
         2005, Saguaro may terminate the acquisition agreement and UniSource
         Energy would be obligated to reimburse up to $7 million of Saguaro's
         expenses.


Q:       What additional regulatory approvals are required?

A:       In addition to approval by the ACC, the acquisition still requires
         approval from the Securities and Exchange Commission under the Public
         Utility Holding Company Act. The requirements under the
         Hart-Scott-Rodino Antitrust Improvements Act were satisfied on March
         19,2004. On October 12, 2004, the Federal Energy Regulatory Commission
         issued anorder approving the proposed acquisition and concluded that 
         the proposed acquisition was "consistent with the public interest."


Q:       Is UniSource Energy planning to pay a 4th quarter dividend to its
         shareholders?

A:       The acquisition agreement allows UniSource Energy to continue to pay
         regular quarterly cash dividends until the closing of the acquisition,
         subject to limitations upon its ability to increase the amount of such
         dividends. UniSource Energy's Board of Directors will decide on the
         quarterly cash dividends on UniSource Energy's Common Stock in
         December.
