ITEM 5.      OTHER EVENTS.

         On June 29, 1995, Enterra Corporation, a Delaware corporation (the
"Company"), and Zapata Corporation, a Delaware corporation ("Zapata"),
entered into a contract providing for the Company's acquisition of Zapata's
natural gas compression businesses ("Zapata Energy Industries") for $130
million.  The contract is subject to expiration or termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and to signing of a definitive asset purchase agreement containing
customary and reasonable representations and warranties and indemnification
provisions.  A dispute has arisen regarding the transaction. While the
Company and Zapata are currently engaged in discussions with respect thereto,
the Company intends to pursue appropriate legal remedies, if necessary, to
complete the transaction. However, there can be no assurance that the Zapata
Energy Industries acquisition will be consummated or that, if consummated,
the final terms will be consistent with the June 29 contract.  If any
additional consideration is paid or if any liabilities are assumed, such will
result in an increase in goodwill and the expected amortization over its
40-year life.

         Zapata Energy Industries is engaged in the business of renting,
fabricating, selling, installing and servicing natural gas compressor
packages used in the oil and gas industry. Natural gas compression is used in
the production, processing and delivery of natural gas.  Zapata Energy
Industries is headquartered in Corpus Christi, Texas and maintains a network
of 15 sales and services offices in Texas, Louisiana, Oklahoma, Arkansas and New
Mexico. While Zapata Energy Industries' operations are primarily domestic, it
sells natural gas compressor packages in several international natural gas
producing regions.  Its customers include natural gas companies which are
involved in the production, processing and transmission of natural gas.
