DISCONTINUED OPERATIONS--NATURAL GAS COMPRESSION
In April 1995, Zapata announced that the Company was considering the sale
of its natural gas compression operations. In June 1995, Zapata announced that
it had entered into an agreement to sell the assets of its natural gas
compression division for $130 million to Enterra Corporation. The agreement is
subject to the signing of a definitive agreement and certain governmental
approvals. The Company is currently negotiating the terms of the agreement,
however, no assurance can be made that this transaction will be completed. The
Company's consolidated financial statements have been restated to reflect the
natural gas compression operations as a discontinued operation.
The major segments of Energy Industries' natural gas compression revenues
and operating results for the three-month and nine-month periods ended June 30,
1995 and the three-month and eight-month periods ended June 30, 1994, in
thousands, are identified below.

Natural gas compressor package rental utilization is affected primarily by
the number and age of producing oil and gas wells, the volume of natural gas
consumed and natural gas prices. Rental rates are determined primarily by the
demand for compressor packages and vary by size and horsepower of a compressor
package. Energy Industries' utilization, rental rates and fleet size as of June
30, 1995 and 1994 are compared in the following table.
