August 23, 2004, among the Company, the Guarantors and the Trustee (as so

      In rendering this opinion, we have examined such documents, records and
matters of law we have deemed necessary. Based upon the foregoing and subject to
the qualifications, limitations and assumptions stated herein, we are of the
opinion that:

            (1) The Exchange Notes, when they are executed by the Company,
authenticated by the Trustee in accordance with the Indenture and delivered in
exchange for the Outstanding Notes in accordance with the terms of the Exchange
Offer, will be validly issued by the Company and will constitute valid and
binding obligations of the Company.

            (2) The Exchange Guarantees, when they are executed and delivered in
accordance with the terms of the Exchange Offer in exchange for the Outstanding
Guarantees, will be validly issued by the Delaware Guarantors and will
constitute valid and binding obligations of the Guarantors.

      Our opinions are limited by bankruptcy, insolvency, reorganization,
fraudulent transfer, conveyance, voidable preference, moratorium or other
similar laws, regulations or judicial opinions of general applicability relating
to or affecting creditors' rights generally, and by general equitable
principles, whether such principles are considered in a proceeding at law or at
equity.

      In rendering the foregoing opinions (i) we have relied as to certain
factual matters upon certificates of officers of the Company, and we have not
independently checked or verified the

accuracy of the statements contained therein and (ii) we have assumed that (A)
the Registration Statement on Form S-4 of the Company and the Guarantors
relating to the Exchange Offer (the "REGISTRATION STATEMENT"), will have become
effective, (B) the resolutions authorizing the Company and the Guarantors to
issue the Securities have been adopted by the Company's and the Guarantors'
Board of Directors or Board of Managers, as the case may be, and will be in full
force and effect at the time at which the Securities are issued and (C) all
Securities will be issued in compliance with applicable federal and state
securities laws. Our examination of matters of law in connection with the
opinions expressed herein has been limited to, and accordingly our opinions are
hereby limited to, the laws of the State of New York and the General Corporation
Law of the State of Delaware. We express no opinion with respect to any other
law of the state of Delaware.

      We are not admitted or qualified to practice law in the State of
Minnesota. Therefore, in rendering our opinions expressed herein, we have relied
solely and without independent investigation upon the opinion of Faegre & Benson
LLP, a copy of which has been filed as Exhibit 5.2 to the Registration
Statement, with respect to matters governed by the laws of the State of
Minnesota.

      We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the Prospectus constituting a part of the Registration Statement. In
giving such consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Securities
Act or the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.

                                                     Very truly yours,
