         Re:    Registration Statement on Form S-4, Registration No. 333-104911
                ---------------------------------------------------------------

Ladies and Gentlemen:

         We are issuing this opinion letter in our capacity as special legal
counsel to Ground Zero, Inc., a Missouri corporation, and Schultz Company, a
Missouri corporation, (together, the "Guarantors"), in connection with the
Guarantors' proposed guarantee, along with the other guarantors under the
Indenture (as defined below), of $235,000,000 in aggregate principal amount of
9 7/8% Series D Senior Subordinated Notes due 2009 (the "Series D notes"). The
Series D notes are to be issued by United Industries Corporation, a Delaware
corporation (the "Issuer"), pursuant to a Registration Statement on Form S-4
(Registration No. 333-104911), originally filed with the Securities and Exchange
Commission (the "Commission") on May 1, 2003, under the Securities Act of 1933,
as amended (the "Act") such Registration Statement, as supplemented or amended,
is hereinafter referred to as the "Registration Statement"). The obligations of
the Issuer under the Series D notes will be guaranteed by the Guarantors (the
"Guarantees"). The Series D notes and the Guarantees are to be issued pursuant
to the Indenture (as supplemented, the "Indenture"), dated as of March 27, 2003,
among the Issuers, the Guarantors, and other parties.

         In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary for the purposes of this
opinion, including (i) the Articles of Incorporation and By-Laws of the
Guarantors, (ii) minutes and records of the corporate proceedings of the
Guarantors with respect to the issuance of the Guarantees, (iii) the
Registration Statement and (iv) the Indenture.

         For purposes of this opinion, we have assumed the authenticity of all
documents submitted to us as originals, the conformity to the originals of all
documents submitted to us as copies and the authenticity of the originals of all
documents submitted to us as copies. We have also assumed the genuineness of the
signatures of persons signing all documents in connection with which this
opinion is rendered, the authority of such persons signing on behalf of the
parties thereto other than the Guarantors and the due authorization, execution
and delivery of all documents by the parties thereto other than the Guarantors.
As to any facts material to the opinions expressed herein which we have not
independently established or verified, we have relied upon statements and
representations of officers and other representatives of the Guarantors and
others.

         Our opinion expressed below is subject to the qualifications that we
express no opinion as to the applicability of, compliance with, or effect of (i)
any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent
conveyance, moratorium or other similar law affecting the enforcement of
creditors' rights generally, (ii) general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law), (iii)
public policy considerations which may limit the rights of parties to obtain
certain remedies and (iv) any law except the laws of the State of Missouri and
the Missouri case law decided thereunder.

         Whenever our opinion herein is indicated to be based on our knowledge,
it is limited to the actual current knowledge of the attorneys of our firm who
have devoted substantive attention to legal matters referred to us by the
Guarantors. Except to the extent expressly set forth herein, however, we have
not undertaken any independent investigation as to such matters, and no
inference as to our knowledge of such matters should be drawn from our
representation of the Guarantors.

         Based upon and subject to the assumptions, qualifications, assumptions
and limitations and the further limitations set forth below, we are of the
opinion that:

              1.    Each of the Guarantors is duly incorporated, validly
         existing and in good standing under the laws of the State of Missouri.

              2.    Each of the Guarantors has the requisite corporate power and
         authority to execute and deliver the Indenture and the Guarantee and to
         perform its obligations thereunder.

              3.    The execution and delivery of the Indenture and the
         Guarantee by each of the Guarantors, and the performance of its
         obligations thereunder, has been duly authorized by each such
         Guarantor, and does not conflict with such Guarantor's articles of
         incorporation, bylaws or, to our knowledge, any applicable provision
         of state law or require any consent of any governmental authority.

         Our opinions above are subject to the following further qualifications
and limitations:

              (a)   we express no opinion as to the effect of the compliance or
         noncompliance of any person or entity other than Guarantors with any
         laws or regulations applicable to such person or entity because of the
         legal or regulatory status or the nature of the business of such person
         or entity.

              (b)   we express no opinion with respect to laws, rules or
         regulations relating to: securities, the environment, food and drugs,
         health and safety, disclosure, misrepresentation or fraud, fraudulent
         transfer and conveyance; and

              (c)   with respect to the opinions contained in paragraph 3, our
         opinions are limited by the effects of principles of unconscionability
         and principles of law that limit or affect the enforceability of
         provisions regarding liquidated damages, break funding fees, prepayment
         fees, late charges and default rates of interest to the extent the same
         are deemed to be a penalty or unreasonable
