Exhibit 5.  - Other Events
- --------------------------

     On March 5, 1999, UniSource Energy Corporation's Board
of Directors adopted a shareholder rights plan pursuant to
which holders of Common Stock outstanding on April 1, 1999,
or issued thereafter, will be granted one preferred share
purchase right ("Right") on each outstanding share of Common
Stock.
     
     The Rights Plan is designed to protect shareholders
interests by causing substantial dilution to a person or
group that attempts to acquire 15% or more of the Company on
terms not approved by the Company's Board of Directors.  Due
to the substantial dilution that could occur, an acquirer
would likely seek approval of the Board of Directors prior
to acquiring 15% or more of the Company.
     
     The Rights would not prevent any merger or other
business combination approved by the Board of Directors of
the Company.    The adoption of the Plan is not in response
to any effort to acquire control of the Company.
     
       Each Right will entitle the registered Shareholder to
purchase one ten-thousandth of a share of Preferred Stock,
Series X, without par value, of the Company at a Purchase
Price of $50 (the "Purchase Price").  The Purchase Price is
subject to adjustment from time-to-time to prevent dilution.

     The Rights will be exercisable only if a person or
group acquires 15% or more of the outstanding shares of
Common Stock or commences a tender or exchange offer, the
consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the
outstanding shares of Common Stock.  Until that time the
Rights will be evidenced by, and will trade with, the shares
of Common Stock.  The Rights expire on March 31, 2009.

     If any person or group acquires 15% or more of the
outstanding shares of Common Stock, each Right will entitle
its holder (other than such person or members of the
acquiring group), to purchase, at the Purchase Price, 
that number of shares of Common Stock or Preferred Shares
which has a market value at that time of twice the Purchase Price.

     In addition, in the event that any person or group has
acquired 15% or more of the outstanding shares of Common
Stock and the Company consolidates or merges with or into,
or sells 50% or more of its assets or earning power to, any
person or group, proper provision will be made so that each
Right would thereafter entitle its holder to purchase at the
Purchase Price that number of the acquiring company's common
shares having a market value at that time of twice the Purchase Price.

     At any time after a person or group acquires more than
15% but less than 50% of the outstanding shares of Common
Stock, the Board of Directors of the Company may require
each outstanding Right to be exchanged for one share of
Common Stock or cash, securities or other assets having a
value equal to the market value of one share of Common
Stock.

     The Company may redeem the Rights at a redemption price
of $0.001 per Right, at any time until any person or group
has acquired 15% or more of the outstanding shares of Common
Stock.  The Company may amend the Rights Agreement in any
respect until any person or group has acquired 15% or more
of the outstanding shares of Common Stock.  Thereafter, the
Company may amend the Rights Agreement in any manner which
will not adversely affect the holders of the Rights.
