                  Registration Statement on Form S-4

Ladies and Gentlemen:

         At your request, we have examined the Registration Statement on Form

cooperative corporation (the "Company"), and each of the following entities
listed therein: ACS Stores, LLC, Advanced Business Concepts International, LLC,
AG2AG, LLC, Agricultural Indemnity Insurance Company, Alliance Milk Products,
LLC, America's Country Stores Holdings, LLC, America's Country Stores, LLC,
Diamond Cross, LLC, FMR, Inc., Forage Genetics, Inc., Golden State Feeds, LLC,
Golden Valley Dairy Products, L.L. Olds Seed Company, Land O'Lakes Farmland Feed
LLC, Land O'Lakes Holdings, Inc., Land O'Lakes International Development
Corporation, LOL Holdings II, Inc., LOL Power, LLC, Milk Products, LLC, North
Coast Fertilizer II, Inc., Northwest Food Products Company, Inc., Northwest Food
Products Transportation, LLC, Nutra-Blend, LLC, PMI Nutrition, LLC, PMI
Agriculture, LLC, PMI Nutrition International, LLC, Purina Mills, LLC, Realty
LOL, Inc., Research Seeds, Inc., Seed Research, Inc., and Thomas Products, LLC
(collectively, the "Subsidiary Guarantors"), which you have filed with the
Securities and Exchange Commission (the "Commission") on April 28, 2004 under
the Securities Act of 1933, as amended (the "Securities Act"), in connection
with the exchange of $175,000,000 principal amount of the Company's 9% Senior
Secured Notes due 2010 (the "Notes") for $175,000,000 principal amount of
Company's outstanding 9% Senior Secured Notes due 2010 (the "Old Notes"). The
Notes will be issued pursuant to an Indenture (including the guarantees of the
Subsidiary Guarantors included therein (the "Guarantees"), the "Indenture")
dated as of December 23, 2003 among the Company, each Subsidiary Guarantor, and
U.S. Bank National Association, as Trustee (the "Trustee"), and will be
guaranteed by such Subsidiary Guarantors pursuant to the Guarantees. Unless
otherwise defined herein, or the context otherwise requires, terms used herein
have the meanings assigned to such terms in, and shall be interpreted in
accordance with, the Indenture.

         We have acted as special counsel to the Company and the Subsidiary
Guarantors in connection with the preparation, execution and delivery of the
Indenture and the Notes and, in

rendering the opinion set forth below, we have reviewed copies, certified or
otherwise identified to our satisfaction, of the Indenture and the Notes.

         As to any facts material to our opinion, we have made no independent
investigation of such facts and have relied, to the extent that we deem such
reliance proper, on certificates of officers of the Company.

         In rendering the opinions set forth below, we have assumed (i) that
each party to any of the Indenture or the Notes has been duly organized and is
validly existing and in good standing (if relevant) under the laws of its
jurisdiction of organization; (ii) that each party to any of the Indenture or
the Notes has full power and authority (corporate and otherwise) to
authenticate, execute, deliver and/or perform, as the case may be, such
document; (iii) that the authentication, execution, delivery and/or performance,
as the case may be, of the Indenture and the Notes by each party thereto have
been duly authorized by all necessary action (corporate and otherwise) on the
part of such party; (iv) that the Indenture and the Notes have been duly
authenticated, executed and/or delivered, as the case may be, by each of the
parties thereto; (v) that the Indenture is valid, binding and enforceable
against the Trustee; (vi) that the authentication, execution, delivery and/or
performance, as the case may be, of each of the Indenture and the Notes by each
party thereto do not and will not violate or constitute a default under any
provision of applicable law or regulation, or any organizational document of any
such party, or any contract, undertaking, judgment, injunction, order, decree or
other instrument to which any such party is a party or by which it or its
properties is bound; (vii) that no authorization, approval, consent, order,
license, franchise, permit or other action by, and no notice to or filing with,
any governmental authority or regulatory body or any other third party is
required for the due authentication, execution, delivery and/or performance, as
the case may be, of any of the Indenture or the Notes by any party thereto that
has not been duly obtained or made and that is not in full force and effect;
(viii) the legal capacity of natural persons; (ix) the genuineness of all
signatures; (x) the authenticity of all documents submitted to us as originals;
(xi) the conformity to the original documents of all documents submitted to us
as copies thereof, and the authenticity of the originals of such latter
documents; (xii) that each of the Trustee and (if relevant) the holders of the
Notes has complied with all legal requirements pertaining to its status as such
status relates to its rights to enforce the Notes and the Indenture against the
Company and the Subsidiary Guarantors; (xiii) that immediately prior to the
exchange contemplated by the Indenture and the Registration Statement, the Old
Notes were in full force and effect (and had been duly authenticated, executed
and/or delivered, as the case may be, by each of the parties thereto), and that
the form of the Notes will conform to that included in the Indenture; (xiv) that
each Subsidiary Guarantor has received adequate consideration to support the
execution and delivery by it of, and that none of the Subsidiary Guarantors has
been released from its obligations under, the Indenture; (xv) that the laws of
any jurisdiction other than the jurisdiction that is the subject of this opinion
letter do not affect the terms of the Notes or the Indenture; (xvi) that there
has not been any mutual mistake of fact or misunderstanding, fraud, duress or
undue influence; and (xvii) that the conduct of the parties to the transaction
has complied with any requirement of good faith, fair dealing and
conscionability.

         Based upon the foregoing and subject to the qualifications, exceptions,
limitations and assumptions set forth herein, we are of the opinion that under
the laws of the State of New York (other than any conflicts of law rule or
principle):

         1. The Indenture (including the Guarantees contained therein)
constitutes a valid and legally binding obligation of the Company and the
Subsidiary Guarantors, enforceable against the Company and the Subsidiary
Guarantors in accordance with its terms.

         2. When duly executed and authenticated as contemplated by the
Indenture and delivered to the holders of the Old Notes in exchange for the Old
Notes as contemplated by the Registration Statement and the Indenture, the Notes
will constitute valid and legally binding obligations of the Company,
enforceable against the Company in accordance with their terms, and will be
entitled to the benefits of the Indenture (including the Guarantees contained
therein).

         Our opinion is subject in all respects to the following qualifications,
exceptions and limitations:

         (a) We express no opinion with respect to the validity or
enforceability of the following provisions to the extent that they are contained
in the Indenture or the Notes: (i) provisions releasing, exculpating or
exempting a party from, or requiring indemnification of or contribution to a
party for, liability for its own negligence, recklessness, willful misconduct or
unlawful conduct to the extent that the same are inconsistent with the public
policy underlying any law, rule or regulation; (ii) choice of law provisions;
(iii) provisions purporting to waive, subordinate or not give effect to rights
to notice, demands, legal defenses or other rights or benefits that cannot be
waived, subordinated or rendered ineffective under applicable law; (iv)
provisions relating to powers of attorney, severability, subrogation,
entitlement to attorneys' fees or set-off rights; (v) provisions providing that
decisions or determinations by a party are conclusive or may be made in its sole
discretion; (vi) provisions imposing penalties or liquidated damages or
requiring the payment of interest on interest or interest at a higher rate than
the rate ordinarily borne by the Notes upon default or the occurrence or failure
to occur of any other conditions; and (vii) provisions requiring that waivers be
in writing.

         (b) The enforceability of the Indenture and the Notes may be limited
by: (i) applicable bankruptcy, insolvency, fraudulent conveyance or transfer,
debt adjustment, reorganization, moratorium, receivership, conservatorship,
composition, liquidation or other similar laws from time to time in effect
relating to, resulting from, restricting, limiting or affecting generally the
enforcement of creditors' rights; (ii) general principles of equity, including
without limitation concepts of materiality, unconscionability, reasonableness,
good faith, and fair dealing (regardless of whether considered in a proceeding
at law or in equity); (iii) the availability of equitable remedies; (iv) the
discretion of a court to grant, impose or render remedies under specific
circumstances; and (v) limitations imposed by public policy, although, except as
noted otherwise herein, we are not aware of any such limitation that would
adversely affect the enforceability of the Indenture or the Notes.

         (c) We express no opinion with respect to suretyship defenses or
defenses in the nature thereof with respect to the obligations of any Subsidiary
Guarantor under the Indenture.
