                                EXPLANATORY NOTE


        The purpose of this Post-Effective Amendment No. 1 is to deregister an
aggregate of $120,102,500 principal amount of 10 1/4% Senior Notes due 2004 and
10 1/4% Senior Notes due 2004, Series B (collectively, the "Notes") of EVI, Inc.
(formerly known as Energy Ventures, Inc.) that were registered under the
Securities Act of 1933 (the "Act") pursuant to a Registration Statement on Form
S-4 (Reg. No. 33-77960) (the "Registration Statement") for sale pursuant to a
market-making prospectus by Lehman Brothers Inc. ("Lehman").  The Registrants
under the Registration Statement included EVI, Inc. (the "Company") and certain
of the Company's subsidiaries acting as subsidiary guarantors of the Notes
(collectively, the "Subsidiary Guarantors").

         In connection with the Company's tender offer and consent solicitation
(the "Tender Offer") for the outstanding Notes, an aggregate of $119,980,000
principal amount of the outstanding Notes (representing 99.9% of the $120
million principal amount of Notes outstanding) validly tendered pursuant to the
Tender Offer and were accepted for payment by the Company on December 15, 1997
(the "Repurchase").  Prior to the Repurchase, the Company entered into a
supplemental indenture (the "Supplemental Indenture") to the indenture
governing the Notes (the "Indenture") incorporating amendments to which
tendering holders of the Notes consented.  These amendments eliminated or
amended certain of the principal restrictive covenants contained in the
Indenture and released all Subsidiary Guarantors under the Indenture.

         As a result of the Repurchase and the execution of the Supplemental
Indenture, Lehman will no longer engage in market-making activities with
respect to the Notes.   Thus, the Company has determined that the Notes that
were registered by Registration Statement can be removed from registration.

         Therefore, pursuant to the undertaking made by the Company required by
Item 512(a)(3) of Regulation S-K, the Company files this Post-Effective
Amendment No. 1 to the Registration Statement for the purpose of removing the
Notes from registration under the Act.
