ITEM 4.  PURPOSE OF TRANSACTION

     Item 4 is amended and restated in its entirety to read as follows:

     On May 9, 2001, OilQuip Rentals Inc., a Delaware corporation ("OilQuip"),
was merged with and into Allis-Chalmers Acquisition Corp., a Delaware
corporation and a wholly owned subsidiary of the Issuer (the "Merger"), pursuant
to the terms of an Agreement and Plan of Merger dated May 9, 2001, a copy of
which is attached as an exhibit hereto (the "Merger Agreement").

     Pursuant to the Merger Agreement, the Issuer issued 400,000 shares of
Common Stock to the former stockholders of OilQuip (including 10,000 shares of
Common Stock issued to RER Corp.) and agreed to issue an additional 9,600,000
shares of Common Stock (including 240,000 shares of Common Stock to be issued to
RER Corp.) on the date the Certificate of Incorporation of the Issuer is amended
to authorize the issuance of such shares. On October 15, 2001, an Amended and
Restated Certificate of Incorporation of the Issuer (the "Amendment") was filed
with the Secretary of State of the State of Delaware, and the above-referenced
additional 9,600,000 shares of Common Stock were issued, including the 240,000
shares of Common Stock issued to RER Corp.

     On October 15, 2001, the Issuer and Mr. Toboroff entered into a Stock
Option Agreement pursuant to which a stock option (the "Toboroff Option") to
purchase 500,000 shares of the Common Stock became exercisable. The Toboroff
Option was originally granted on May 31, 2001 but was not exercisable until the
Issuer filed the Amendment.

     In December 2001, AL-CH effected the transfer of all of the shares of
Common Stock of the Issuer held by it to the partners of AL-CH, including the
89,310 shares transferred to Q.E.N. Inc. (a corporation controlled by Mr.
Nederlander), the 64,303 shares transferred to Leonard Toboroff P.C. Profit
Sharing Trust 002 and the 25,006 shares transferred to Lenny Corp. (a
corporation controlled by Mr. Toboroff). On December 19, 2001, a Certificate of
Cancellation of Limited Partnership of AL-CH was filed with the Secretary of
State of the State of Delaware. AL-CH no longer beneficially owns any shares of
Common Stock.

     Each of the Reporting Persons acquired shares of Common Stock as an
investment. Each of the Reporting Persons may seek to acquire or dispose of
shares of Common


                                  Page 7 of 9




Stock through open market or privately negotiated transactions from time to time
in its or his discretion. Any such purchases will depend upon the market prices
for the shares of Common Stock, the number of shares which may become available
for purchase at prices which each of the Reporting Persons regard as attractive
and various other factors which each of the Reporting Persons may determine to
be relevant.

     Except for the foregoing, no Reporting Person has any present plans or
proposals which relate to or would result in any of the actions or events
described in paragraphs (a) through (j) of Item 4 of Schedule 13D. However, the
Reporting Persons retain their respective rights to modify their plans with
respect to the transactions described in this Item 4, to acquire or dispose of
securities of the Issuer and to formulate plans and proposals which could result
in the occurrence of any such events, subject to applicable laws and
regulations.
