                               EXCHANGE AGREEMENT


     THIS EXCHANGE AGREEMENT (the "Agreement") is made as of June 14, 2002,
among Bayer Corporation, an Indiana corporation ("Bayer") with a place of
business at 8400 Hawthorne Road, Kansas City, MO 64120, and Bayer Advanced LLC,
a Delaware limited liability company ("Advanced" and together with Bayer, the
"Bayer Parties"), with its principal place of business at 1500 Urban Center
Parkway, Suite 350, Birmingham, Alabama 35242, and United Industries
Corporation, a Delaware corporation, with its principal place of business at
8825 Page Boulevard, St. Louis, Missouri 63114 (the "Company"). The Bayer
Parties and the Company are each individually referred to herein as a "Party",
and collectively, as the "Parties".

     The Bayer Parties wish to deliver to the Company two notes issued by
Pursell Industries, Inc. and its subsidiaries ("Pursell") on November 30, 2000
(a $10,000,000 note issued to Bayer and secured by certain personal property of
Pursell's (the "Secured Note"), and a $23,498,436 note, issued to Advanced (the
"Unsecured Note", and together with the Secured Note, the "Notes", both attached
as EXHIBIT A hereto) and the Company wishes to deliver to the Bayer Parties that
number and class of shares of common stock of the Company (the "Shares") as are
indicated on EXHIBIT B attached hereto. The Company and the Bayer Parties are
willing, on the terms and conditions contained in this Agreement, to exchange
the Notes for the Shares. Certain provisions of this Agreement (including
Sections 3, 4, 6, 8 and 9) are intended for the benefit of, and shall be
enforceable by, United Industries Holdings, L.L.C. ("Holdings") as if it were a
party hereto.

     Now therefore, in consideration of the premises hereof and the material
covenants contained herein, and other valuable consideration (including the
Service Agreement and the Supply Agreement), the receipt and sufficiency of
which are hereby acknowledged, the parties hereto hereby agree as follows:

     1. EXCHANGE.

     (a) In accordance with the Closing Agreement (as defined in Section 2
below), upon execution of this Agreement, the Company shall deliver to the Bayer
Parties the certificates representing the Shares, and the Bayer Parties shall
deliver to the Company the Notes, duly assigned to the Company.

     (b) In connection with the exchange, the Bayer Parties represent and
warrant to the Company that:

          (i) The Shares to be acquired by the Bayer Parties pursuant to this
     Agreement shall be acquired for the Bayer Parties own accounts and not with
     a view to, or intention of, distribution thereof in violation of the 1933
     Act, or any applicable state securities laws, and the Shares shall not be
     disposed of in contravention of the 1933 Act or any applicable state
     securities laws.

          (ii) The Bayer Parties are sophisticated in financial matters and are
     able to evaluate the risks and benefits of the investment in the Shares.

          (iii) The Bayer Parties are able to bear the economic risk of their



                                          Confidential Information redacted
                                          filed separately with the Commission.

     investment in the Shares for an indefinite period of time because the
     Shares have not been registered under the 1933 Act and, therefore, cannot
     be sold unless subsequently registered under the 1933 Act or an exemption
     from such registration is available.

          (iv) The Bayer Parties understand that the purchase of the Shares
     involves substantial risk and that their financial condition and
     investments are such that they are in a financial position to hold the
     Shares for an indefinite period of time and to bear the economic risk of,
     and withstand a complete loss of, their investment in such Shares. In
     addition, by virtue of their expertise, the advice available to them and
     previous investment experience, the Bayer Parties have extensive knowledge
     and experience in financial and business matters, investments, securities
     and private placements and the capability to evaluate the merits and risks
     of the transactions contemplated by this Agreement. The Bayer Parties
     represent that they are each individually sophisticated and an "accredited
     investor" as that term is defined in Regulation D promulgated under the
     1933 Act.

          (v) During the negotiation of the transactions contemplated herein,
     the Bayer Parties and their representatives have been given (i) access to
     corporate books, financial statements, records, contracts, documents, and
     other information concerning the Company and to its offices and facilities,
     (ii) an opportunity to ask questions of the Company's officers and
     employees concerning the Company's business, operations, financial
     condition, assets, liabilities and other relevant matters as they have
     deemed necessary or desirable, and (iii) such information as has been
     requested, in order to evaluate the merits and risks of the prospective
     investment contemplated herein.

          (vi) The Bayer Parties have all requisite corporate or limited
     liability company power and authority to enter into this Agreement and to
     consummate the transactions contemplated hereby. The execution and delivery
     of this Agreement, and the Joinder Agreement to the Stockholders Agreement
     (making the Bayer Parties parties thereto and Stockholders, as such term is
     used therein, thereunder), and the consummation of the transactions
     contemplated hereby and thereby have been duly authorized by all necessary
     corporate or limited liability company action on the part of the Bayer
     Parties, and no further action is required on the part of the Bayer Parties
     to authorize this Agreement and the transactions contemplated hereby. Each
     of this Agreement and the Joinder Agreement have been duly executed and
     delivered by the Bayer Parties and, assuming the due authorization,
     execution and delivery by the Company, constitute valid and binding
     obligations of the Bayer Parties, enforceable in accordance with their
     terms, except as such enforceability may be limited by the laws of general
     application relating to bankruptcy, insolvency and the relief of debtors
     and to rules of law governing specific performance, injunctive relief or
     other equitable remedies.

          (vii) Except as provided on SCHEDULE 1(b)(VII), the execution and
     delivery by the Bayer Parties of this Agreement and the First Amendment (as
     defined below) and the consummation of the transactions contemplated hereby
     and thereby will not conflict with or result in any violation of or default
     under (with or without notice or lapse of time, or both) or give rise to a
     right of termination, cancellation, modification or acceleration of any
     obligation or loss of any benefit under (i) any provision of the
     Certificate of Incorporation and Bylaws, or limited liability company
     agreement, as appropriate, of either of the Bayer Parties, (ii) any
     mortgage, indenture, lease, contract or other agreement or instrument,
     permit,

                                         Confidential Information redacted and
                                         filed separately with the Commission.






     concession, franchise or license to which the Bayer Parties or any of its
     properties or assets is subject, or (iii) any judgment, order, decree,
     statute, law, ordinance, rule or regulation applicable to the Bayer Parties
     or its properties or assets.

          (viii) Except as may be required by any state "blue sky" laws or as
     described on SCHEDULE 1(b)(VIII) attached hereto, no authorization,
     consent, approval, license, qualification or formal exemption from, nor any
     filing, declaration or registration with, any court, governmental agency,
     regulatory authority or political subdivision thereof, any securities
     exchange or any other Person (including, without limitation, Pursell) is
     required in connection with the execution, delivery or performance by the
     Bayer Parties of this Agreement or the transactions contemplated hereby,
     except for any such authorizations, consents, approvals, licenses,
     qualifications, exemptions, filings, declarations and registrations as have
     been obtained or made, as the case may be, and which are in full force and
     effect and are not the subject of any pending or, to the Bayer Parties'
     knowledge, threatened attack by appeal or direct proceeding or otherwise.

          (ix) As of the date hereof, and after giving effect to the exchange
     contemplated hereby, (A) the unpaid principal amount of the Secured Note
     will be $10,000,000 and the accrued and unpaid interest as of June 7, 2002
     on the Secured Note will be $12,603; and (B) the unpaid principal amount of
     the Unsecured Note as of January 31, 2002 was $26,052,719. Pursuant to the
     terms of the Notes, if the Agency Agreement, dated as of December 1, 2000
     (the "Pursell Agency Agreement"), between Pursell and Advanced, is
     terminated by Advanced for any reason other than a failure by Pursell to
     achieve and satisfy certain key performance indicators, the principal
     amount of the Notes will automatically be reduced in accordance with the
     formula set forth in the Notes. It is a condition to Bayer's and Advanced's
     consummation of certain transactions provided for in the In-Store Service
     Agreement with the Company, dated as of the date hereof (the "Service
     Agreement") that Advanced terminate the Pursell Agency Agreement. As a
     result, the Company hereby acknowledges that the principal amount of the
     Notes will be reduced as described above in order for Bayer and Advanced to
     make certain provisions of the Service Agreement effective. In addition,
     the Company hereby acknowledges that it has recently performed due
     diligence with respect to the assets, businesses and financial condition of
     Pursell and is aware of the impact that Pursell's current financial
     condition could have on the value and collectibility of the Notes. The
     Secured Note is secured by a lien on certain assets of Pursell and certain
     of its affiliates, all as described in the Security Agreement, dated as of
     November 30, 2000, among Pursell, BFC Acquisition Corporation, and Vigoro
     Acquisition Corp., as debtors, and Bayer, as secured party, as amended by
     that certain letter agreement, dated as of December 13, 2001, between Bayer
     and the Company, relating to the release of liens (as amended, the
     "Security Agreement"), a copy of which is attached hereto as EXHIBIT C. The
     Security Agreement creates a valid security interest in favor of the Bayer
     Parties (and after due execution of the Assignment and Assumption Agreement
     (as defined in the Closing Agreement), in favor of the Company), in
     Pursell's rights in the collateral described in the Security Agreement (the
     "Collateral"), and the Bayer Parties have, and after giving effect to the
     Assignment and Assumption Agreement, the Company will acquire, a valid,
     fully perfected security interest in that portion of the Collateral that
     may be perfected by filing a financing statement in the jurisdictions set
     forth on EXHIBIT D hereto, and such security interest shall be free and
     clear of all liens, claims, encumbrances and other restrictions, except for
     those set forth in the Intercreditor Agreement and Debt Subordination
     Agreement, each as defined below.

                                         filed separately with the Commission.




          (x) The Notes are legal, valid and binding obligations of Pursell,
     enforceable in accordance with their terms, and are in full force and
     effect, and, immediately after transfer by the Bayer Parties to the
     Company, the Notes will remain legal, valid and binding obligations of
     Pursell (subject to a writedown of principal under the circumstances
     described in (ix) above), enforceable in accordance with their terms, and
     in full force and effect on identical terms for the benefit of the Company
     following the consummation of the transactions contemplated hereby; no
     party is in breach or default under the Notes; no event has occurred which
     with notice or lapse of time would constitute a breach or default, or
     permit termination, modification, or acceleration, under the Notes; and no
     party has repudiated any provision of the Notes. The Bayer Parties own the
     Notes beneficially and of record, free and clear of all liens,
     encumbrances, security interests, voting agreements, voting trusts or other
     arrangements or restrictions (except for restrictions set forth in the
     Intercreditor Agreement, dated as of November 30, 2000 (the "Intercreditor
     Agreement") and the Debt Subordination Agreement, dated as of November 30,
     2000 (the "Debt Subordination Agreement")), and upon delivery of the Notes
     to the Company pursuant to clause (a) above, shall transfer to the Company
     good and valid title to the Notes, free and clear of all liens or
     encumbrances (except for restrictions set forth in the Intercreditor
     Agreement and the Debt Subordination Agreement).

     (c) In connection with the exchange, the Company represents and warrants to
the Bayer Parties that:

          (i) The Company is a corporation duly organized and validly existing
     under the laws of the State of Delaware and is qualified to do business in
     every jurisdiction in which its ownership of property or conduct of
     business requires it to qualify, except for such jurisdictions in which the
     failure to so qualify would not have and would not be reasonably expected
     to have a material adverse effect on its business, operations, assets or
     financial condition (excluding prospects) (a "Material Adverse Effect") of
     the Company. The Company has all requisite corporate power and authority
     and all material licenses, permits and authorizations to carry on its
     businesses as now conducted and presently proposed to be conducted.

          (ii) The Company has heretofore furnished the Bayer Parties with the
     consolidated balance sheets of the Company and its subsidiaries as of
     December 31, 2001 and 2000 and the related consolidated statements of
     operations, changes in stockholder's equity and cash flows for the periods
     then ended, audited by PricewaterhouseCoopers LLP (collectively, the
     "Audited Financial Statements") and the unaudited consolidated balance
     sheet of the Company as of March 31, 2002, and the related unaudited
     consolidated statements of operations, changes in stockholder's equity and
     cash flows for the three months then ended (the "Unaudited Financial
     Statements" and together with the Audited Financial Statements, the
     "Financial Statements"). Such Financial Statements including the footnotes
     thereto, except as indicated therein, have been prepared in accordance with
     generally accepted accounting principles applied on a consistent basis
     throughout the periods covered thereby, are consistent with the books and
     records of the Company, fairly present in all material respects the
     financial position of the Company and its subsidiaries and the results of
     their operations and cash flows at such dates and for such periods, except
     that the

                                       4

                                         Confidential Information redacted and
                                         filed separately with the Commission.




     Unaudited Financial Statements (including the Balance Sheet) do not contain
     footnotes and are subject to year-end adjustments.

          (iii) The Company has filed all forms, reports and documents with the
     Securities and Exchange Commission (the "Commission") required to be filed
     by it pursuant to the federal securities laws and the Commission rules and
     regulations thereunder, and all forms, reports and documents filed with the
     Commission by the Company (collectively, the "Commission Filings") have
     complied in all material respects with the applicable requirements of the
     Federal securities laws and the Commission rules and regulations
     promulgated thereunder. As of their respective dates, the Commission
     Filings did not contain any untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading.

          (iv) Other than as previously disclosed to the Bayer Parties, since
     December 31, 2001, to the Company's knowledge, no event has occurred or
     circumstance exists that would reasonably be expected to cause a material
     adverse change in the business, operations, assets or financial condition
     (excluding prospects) of the Company and its subsidiaries taken as a whole
     not otherwise related to industry or economic conditions.

          (v) The Company has all requisite corporate power and authority to
     enter into this Agreement and to consummate the transactions contemplated
     hereby. The execution and delivery of this Agreement and the consummation
     of the transactions contemplated hereby have been duly authorized by all
     necessary corporate action on the part of the Company, and no further
     action is required on the part of the Company to authorize this Agreement
     and the transactions contemplated hereby. This Agreement has been duly
     executed and delivered by the Company and, assuming the due authorization,
     execution and delivery by the Bayer Parties, constitutes a valid and
     binding obligation of the Company, enforceable in accordance with its
     terms, except as such enforceability may be limited by the laws of general
     application relating to bankruptcy, insolvency and the relief of debtors
     and to rules of law governing specific performance, injunctive relief or
     other equitable remedies.

          (vi) The execution and delivery by the Company of this Agreement and
     the consummation of the transactions contemplated hereby will not conflict
     with or result in any violation of or default under (with or without notice
     or lapse of time, or both) or give rise to a right of termination,
     cancellation, modification or acceleration of any obligation or loss of any
     benefit under (i) any provision of the Certificate of Incorporation and
     Bylaws of the Company, (ii) any mortgage, indenture, lease, contract or
     other agreement or instrument, permit, concession, franchise or license to
     which the Company or any of its properties or assets is subject, or (iii)
     any judgment, order, decree, statute, law, ordinance, rule or regulation
     applicable to the Company or its properties or assets.

          (vii) Immediately following the consummation of the transactions
     contemplated by this Agreement, the authorized capital stock of the Company
     will consist of (i) 40,000 shares of Class A Preferred, of which 37,600
     shares shall be issued and outstanding; (ii) 43,600,000 shares of Class A
     Voting Common, of which 30,071,000 shares shall be issued and outstanding,
     (iii) 43,600,000 shares of Class B Non-Voting Common, of which 30,071,000
     shares shall be issued and outstanding, (iv) warrants to purchase 4,750,000

                                         Confidential Information redacted and
                                         filed separately with the Commission.



     shares of Class A Voting Common and 4,750,000 shares of Class B Non-Voting
     Common and (v) options to purchase 2,745,750 shares of Class A Voting and
     2,745,750 shares of Class B Non-Voting Common. Each share of capital stock
     of the Company issued and outstanding as of the date hereof is duly
     authorized, validly issued, fully paid and nonassessable and, except with
     respect to the Stockholders Agreement, is free and clear of all preemptive
     rights, repurchase rights, and liens.

          (viii) Upon issuance by the Company to the Bayer Parties pursuant to
     this Agreement, the Shares shall be duly authorized, validly issued, fully
     paid and nonassessable and, except as otherwise provided in the
     Stockholders Agreement and this Agreement, free and clear of all
     encumbrances or liens. Except as set forth on SCHEDULE 1(c)(VIII) attached
     hereto, there are no binding contracts or agreements of the Company
     relating to the future sale or issuance of any equity securities (or
     securities convertible or exchangeable into equity securities) of the
     Company. None of the outstanding equity securities (or securities
     convertible or exchangeable into equity securities) of the Company were,
     and (assuming the accuracy of the Bayer Parties representations and
     warranties contained in this Agreement) upon issuance to the Bayer Parties
     hereunder the Shares will not be, issued in violation of the 1933 Act.

          (ix) Except as may be required by any state "blue sky" laws, and
     Regulation D of the 1933 Act, no authorization, consent, approval, license,
     qualification or formal exemption from, nor any filing, declaration or
     registration with, any court, governmental agency, regulatory authority or
     political subdivision thereof, any securities exchange or any other Person
     is required in connection with the execution, delivery or performance by
     the Company of this Agreement or the business of the Company, except for
     any such authorizations, consents, approvals, licenses, qualifications,
     exemptions, filings, declarations and registrations that have been obtained
     or made, as the case may be, and are in full force and effect and are not
     the subject of any pending or, to the Company's knowledge, threatened
     attack by appeal or direct proceeding or otherwise.

          (x) TAX RETURNS. The Company has filed, or caused to be filed, in a
     timely manner all tax returns, reports and declarations which are required
     to be filed by it. All information in such tax returns, reports and
     declarations is complete and accurate in all material respects. The Company
     has paid or caused to be paid all material Taxes (as defined below) due and
     payable or claimed due and payable in any assessment received by it, except
     Taxes the validity of which are being contested in good faith by
     appropriate proceedings diligently pursued and available to the Company and
     with respect to which adequate reserves have been set aside on its books.

          (xi) COMPLIANCE WITH LEGAL REQUIREMENTS. Except as set forth on
     SCHEDULE 1(c)(XI) attached hereto, the Company is in compliance with each
     Legal Requirement or Governmental Authorization that is applicable to it or
     to the conduct or operation of its business or the ownership or use of any
     of its assets, except for such non-compliance that would not reasonably be
     expected to have a Material Adverse Effect on the Company.

          (xii) LEGAL PROCEEDINGS; ORDERS. There is no present investigation by
     any Governmental Body pending, or to the best of the Company's knowledge
     threatened, against

                                       6

                                         Confidential Information redacted and
                                         filed separately with the Commission.



     or affecting the Company, its assets or business and there is no action,
     suit, proceeding, order, award, decision, injunction, judgment, ruling or
     claim by any Person pending, or to the best of the Company's knowledge
     threatened, against the Company or its assets or goodwill, or against or
     affecting any transactions contemplated by this Agreement, the First
     Amendment or the Service Agreement, which if adversely determined against
     the Company would reasonably be expected to result in a Material Adverse
     Effect on the Company.

          (xiii) CONTRACTS; NO DEFAULTS. The Company is not in default under, or
     in violation of any of the terms of, any material agreement, contract,
     instrument, lease or other commitment to which it is a party or by which it
     or any of its assets are bound, the default or violation of which would
     reasonably be expected to have a Material Adverse Effect.

     2. REPURCHASE OPTION.

     (a) In the event the Service Agreement terminates pursuant to the terms
thereof (the "TERMINATION"), the Shares (whether held by the Bayer Parties or
one or more of the Bayer Parties' transferees) shall be subject to repurchase by
the Company or its Designee (as defined below) pursuant to the terms and
conditions set forth in this Section 2 (the "REPURCHASE OPTION").

     (b) With respect to the Repurchase Option, the Company or its Designee
shall repurchase the Shares as follows: (i) the purchase price for the Multiple
Shares (as defined below) shall be the Multiple Price; (ii) the purchase price
for all other Shares shall be the lower of the Multiple Price or the Fixed Price
(the "OTHER SHARES"). For purposes of this Agreement, the term "MULTIPLE SHARES"
means that number of shares of capital stock of the Company equal to the number
of Shares held by the Bayer Parties at the time the Company or its Designee
exercises the Repurchase Option multiplied by a fraction, the numerator of which
is the number of Quarterly Installments (as defined in the Service Agreement)
made by the Bayer Parties to the Company as of the time that the Company or its
Designee exercises the Repurchase Option, and the denominator of which is 28. In
exercising its rights under this Section 2, the Company shall repurchase all of
the Shares in a single transaction.

     (c) The board of directors of the Company (the "BOARD") may elect for the
Company to purchase, or appoint a designee or designees (the "DESIGNEES") to
purchase, all of the Multiple Shares and all of the Other Shares by delivering
written notice (the "REPURCHASE NOTICE") to the holder or holders of the Shares
within 365 days after the Termination; provided that if the Termination occurs
in or at the end of the seventh year of the term of the Service Agreement, the
Repurchase Notice must be delivered by the seventh anniversary of the date of
the Service Agreement (or if such Termination occurs on the seventh anniversary
of the date of the Service Agreement, within 30 days thereafter). The Repurchase
Notice shall set forth the number of Multiple Shares and Other Shares to be
acquired from each holder of Shares, the aggregate consideration to be paid for
such Shares and the time and place for the closing of the transaction.

     (d) The closing of the purchase of the Shares pursuant to the Repurchase
Option shall take place on the date designated by the Company in the Repurchase
Notice, which date shall not be more than 60 days nor less than five days after
the delivery thereof. The Company and/or the Designees shall pay for the Shares
to be purchased pursuant to the Repurchase Option by delivery of a certified or
cashier's check or by a wire transfer of immediately available funds; provided
that the Company may pay the purchase price for such Shares by offsetting
amounts (on a dollar for dollar basis and without discount) outstanding under
any bona fide debts owed by the Bayer Parties
