NOTE 5.  SUBSEQUENT EVENT

      On June 30, 1995, Zapata announced that it had entered into an
agreement to sell the assets of Zapata Energy Industries for $130 million to
Enterra Corporation.  The agreement is subject to the signing of a definitive
agreement containing customary and reasonable representations and warranties
and indemnification provisions and certain government approvals.

      As of June 30, 1995, the Company was not in compliance with certain
cash flow covenants related to its Texas Commerce Bank loan.  As a result of
the covenant violation, the total balance outstanding of $26,800,000 at June
30, 1995 related to this loan is reflected as a current liability.
