      Re:   Milacron Inc. $225,000,000 Principal Amount of 11-1/2% Senior
            Secured Notes Due 2011

      We have acted as special Minnesota counsel to Northern Supply Company,
Inc., a Minnesota corporation (the "Minnesota Guarantor") and a subsidiary of
Milacron Inc., a Delaware corporation ("Milacron"), in connection with the
proposed issuance and exchange (the "Exchange Offer") of up to $225,000,000
principal amount of Milacron's 11-1/2% Senior Secured Notes due 2011 (the
"Original Notes") for a like principal amount of Milacron's 11-1/2% Senior
Secured Notes due 2011 (the "Exchange Notes" and, together with the Original
Notes, the "Notes") to be registered under the Securities Act of 1933, as
amended (the "Act"). The Exchange Notes are to be issued pursuant to the
Indenture dated as of May 26, 2004 (the "Indenture"), between Milacron Escrow
Corporation, a Delaware corporation that was merged with and into Milacron, and
U.S. Bank National Association, as trustee (the "Trustee"), as supplemented by
the Supplemental Indenture dated as of June 10, 2004 (the "Supplemental
Indenture"), among Milacron, Milacron's subsidiaries listed on Schedule A
thereto (the "Guarantors") and the Trustee, pursuant to which Milacron assumed
all of the obligations of Milacron Escrow Corporation under the Indenture and
the Guarantors agreed to guarantee the Notes on the terms and subject to the
conditions set forth in the Indenture.

      In connection with this opinion, we have examined, caused the examination
of, or are otherwise familiar with, originals or copies certified or otherwise
identified to our satisfaction, of the documents specified in Part A of Annex I
hereto (the "SPECIFIED DOCUMENTS") as well as the corporate documents for the
Minnesota Guarantor described in Part B of Annex I hereto (the "COMPANY
CORPORATE DOCUMENTS"). We have also relied, with respect to certain factual
matters, on the representations of the Minnesota Guarantor contained in the
Specified Documents and the Company Corporate Documents and have assumed
compliance by the Minnesota Guarantor with the terms of the Specified Documents.

      In connection with this opinion, we have examined and are familiar with
the foregoing Specified Documents and Company Corporate Documents. We have not
been provided with, and have not examined any other documents beyond the
Specified Documents and Minnesota Guarantor Corporate Documents and are not
familiar with the transactions of Milacron, other Guarantors and/or the
Minnesota Guarantor other than as described in the Specified Documents, and are
not familiar with and have not investigated any restrictions or limitations on
the power and authority of the Minnesota Guarantor to conduct its business and
enter into and perform the transactions as described in the Specified Documents
which may exist by virtue of agreements the Minnesota Guarantor has made or is
bound by which have not been provided to us or by virtue of regulation of the
business or transaction by governmental or quasi-governmental authorities.
Except to the extent otherwise expressly set forth herein, for purposes of this
opinion, we have made no factual or independent investigation of, or reviewed,
any contract or agreement which may have been executed by or which may now be
binding upon any of the Trustee, purchasers of the Notes or the Minnesota
Guarantor, nor have we undertaken to review any files of any of the Trustee,
purchasers of the Notes, Milacron, any of the other parties providing guarantees
of the Exchange Notes or the Minnesota Guarantor, or to discuss the respective
transactions or business with any other lawyers in our firm or with the officers
or principals of any of the foregoing.

      Members of our firm are admitted to the Bar of the State of Minnesota and
this opinion is limited to the laws of the State of Minnesota.
