ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         Allis-Chalmers Corporation ("Company") entered into a joint venture
agreement with a division of M-I L.L.C., and related financing on July 1, 2003.
The Company through its subsidiary, Mountain Compressed Air, Inc., and M-I
L.L.C. each contributed assets with a combined fair market value in excess of
$27 million and combined net book value of approximately $13 million to AirComp
L.L.C. ("AirComp"). Mountain Compressed Air contributed substantially all of its
compressed air drilling assets with an estimated fair market value of
approximately $14.8 million net book value of approximately $7.2 million to
AirComp, which the Company believes will be the world's second largest provider
of air compressor products and services to the oil, natural gas and geothermal
drilling workover and completion industries. Allis-Chalmers will own 55% and M-I
L.L.C. will own 45% of AirComp L.L.C.

         In connection with the transaction, AirComp obtained bank financing of
$8 million, of which $7.3 million was distributed to the Company. The debt bears
interest at a floating rate, currently LIBOR plus 0.5% annually. AirComp has the
ability to borrow an additional $2 million under its credit agreement with the
bank. AirComp's bank debt is secured by substantially all of the assets of
AirComp. The Company used these funds to retire debt of Mountain Compressed Air,
Inc. and for general working capital purposes at AirComp. As a result of the
debt repayment, the Company is in compliance with all of its loan covenants with
its bank lenders. The Company has guaranteed all of Mountain Compressed Air's
obligations under the joint venture agreement, and Mountain Compressed Air has
guaranteed up to $2 million of AirComp's debt.
