ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On December 7, 2004, we entered into amended credit facilities with Wells Fargo
Credit, Inc. which replaced credit facilities maintained by Allis-Chalmers
Corporation, and its subsidiaries Jens' Oilfield Service, Inc. and Strata
Directional Technology, Inc. with Wells Fargo Credit, Inc. and with Wells Fargo
Energy Capital, Inc. The credit agreement governing The facilities was entered
into by Allis-Chalmers, Jens', Strata and our New Safco subsidiary, and is
guaranteed by our MCA and OilQuip subsidiaries. The new facilities include:

* A $10.0 million revolving line of credit to replace and increase the existing
lines of credit at Jens' of $1.0 million and at Strata of $4.0 million.
Borrowings are subject to a borrowing base based on eligible accounts
receivables, as defined.

* A term loan in the amount of $6.3 million to be repaid in equal monthly
installments based on a five-year repayment schedule. Proceeds of the term loan
were used to prepay the term loan owed by our Jens' subsidiary and to prepay our
12% $2.3 million subordinated note and retire its related warrants.

* A $6.0 million capital expenditure and acquisition line of credit. Borrowings
under this facility are required to be repaid monthly based on a four-year
repayment schedule after a one year interest only availability period.
Availability of this capital expenditure term loan facility is subject to
security acceptable to the lender in the form of equipment or other acquired
collateral.

The new credit facility is due and payable December 31, 2007 and is secured by
liens on substantially all our assets. The agreement governing these credit
facilities contains customary events of default and financial covenants. It also
limits our ability to incur additional indebtedness, make capital expenditures,
pay dividends or make other distributions, create liens, and sell assets. The
interest rate payable on borrowings is based on the prime rate plus a margin.
