ITEM 5.    OTHER EVENTS AND REGULATION FD DISCLOSURE


On June 21, 2001, United States District Court Judge Roslyn O. Silver in
Phoenix, Arizona, issued an Order dismissing with prejudice Southern Union
Company's (Southern Union) fraudulent inducement causes of action against
Southwest Gas Corporation's (the Company) Chairman of the Board Thomas Hartley
and the Company's Executive Vice President/Consumer Resources and Energy
Services Edward Zub. The Court also dismissed Southern Union's tortious
interference claims against the Company's President and Chief Executive Officer
Michael Maffie.

Given that all of Southern Union's causes of action against Mr. Hartley and
Mr. Zub have been dismissed, Mr. Hartley and Mr. Zub are no longer parties to
the lawsuit.  The Court also dismissed Southern Union's fraudulent inducement
claims against other parties to the lawsuit, including ONEOK, Inc. and
Arizona Corporation Commissioner James Irvin.

The Company has a motion for summary judgment currently pending before the Court
and plans to file additional motions that, if granted, would dismiss the few
remaining Southern Union claims against the Company and Mr. Maffie. A trial date
of November 12, 2001 is presently set. It is anticipated that the trial could
last two to three months.

This filing may contain statements which constitute "forward-looking statements"
within the meaning of the Securities Litigation Reform Act of 1995 (Reform Act).
All such forward-looking statements are intended to be subject to the safe
harbor protection provided by the Reform Act. A number of important factors
affecting the business and financial results of the Company could cause actual
results to differ materially from those stated in the forward-looking
statements. These factors include, but are not limited to, the impact of weather
variations on customer usage, natural gas prices, the effects of
regulation/deregulation, the timing and amount of rate relief, changes in
capital requirements and funding, resolution of pending litigation,
acquisitions, and competition.
