ITEM 1.          DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

                 On April 26, 1996, the Board of Directors of MESA Inc. (the
"Company") amended the Rights Agreement dated as of July 6, 1995 (as amended,
the "Rights Agreement") between the Company and American Stock Transfer and
Trust Company, as Rights Agent.  The amendment amended the definition of the
term "Acquiring Person" to exclude therefrom DNR- Mesa Holdings, L.P., a Texas
limited partnership ("DNR") in connection with the execution and performance of
a Stock Purchase Agreement entered into on the same date between the Company
and DNR, and the beneficial ownership by DNR of stock in the Company resulting
therefrom.  In addition, the definitions of "Series A Preferred Stock" and
"Series B Preferred Stock" were added to describe the Series A 8% Cumulative
Convertible Preferred Stock to be issued pursuant to a rights offering to
shareholders and the Series B 8% Cumulative Convertible Preferred Stock to be
purchased by DNR pursuant to the Stock Purchase Agreement, respectively.

                 A copy of Amendment No. 2 to the Rights Agreement has been
filed with the Securities and Exchange Commission as an exhibit to this
Amendment to Registration Statement on Form 8-A.  This summary description of
the Rights does not purport to be complete and is qualified in its entirety by
reference to the Rights Agreement (as amended), which is incorporated herein by
reference.

                 A copy of the Stock Purchase Agreement was filed as Exhibit 10
to the Company's Form 8-K filed on April 29, 1996, and which is incorporated
herein by reference.
