                  WHEREAS, it is the desire of the Company to amend the Plan in

                  WHEREAS, immediately following the Effective Time, the
Successor Company and the Company entered into an agreement (the "Reorganization

                  WHEREAS, the Company reserved the right, pursuant to Section

and

                  WHEREAS, the Company reserved the right, under Section 10 of

                  NOW, THEREFORE, pursuant to Sections 10 and 12 of the Plan,
the Board of Directors hereby amends the Plan as follows, effective, unless
otherwise indicated, as of the Effective Time:

         1. The name of the Plan is hereby changed to the "RPM International
Inc. 1989 Stock Option Plan."

         2. The Plan is hereby amended by the deletion of each reference to the
term "RPM, Inc." as a corporate entity, including but not limited to, the
definition of the term "Company" in Section 1, and the substitution in lieu
thereof of the term "RPM International Inc." as the corporate entity.

         3. The Plan is hereby amended by the deletion of each reference to the
term "RPM, Inc." as the sponsor of the Plan, including but not limited to, the
name of the Plan, and the substitution in lieu thereof of the term "RPM

         4. The Plan is hereby amended by the deletion of Section 1 in its
entirety and the substitution in lieu thereof of a new Section 1 to read as
follows:

         "1.      Purpose of the Plan

         The Plan is intended to provide a method of providing key employees of
RPM International Inc. (the "Company") and its subsidiaries with greater
incentive to serve and promote the interests of the Company and its
shareholders. The premise of the Plan is that, if such key employees acquire a
proprietary interest in the business of the Company or increase such proprietary
interest as they may already hold, then the incentive of such key employees to
work toward the Company's continued success will be commensurately increased.
Accordingly, the Company will, from time to time during the effective period of
the Plan, grant to such



                                       2

employees as may be selected to participate in the Plan options to purchase
shares of Common Stock, par value $.01 per share ("Shares"), of the Company on
the terms and subject to the conditions set forth in the Plan."

         5. The Stock Option Agreements previously entered into by and between
the Company and the Optionees are hereby amended as follows:

                  (a) effective as of the Effective Time, the Stock Option
         Agreements are hereby amended so that, notwithstanding any other
         provisions of such Stock Option Agreements, (i) the Successor Company
         shall be deemed to have entered into such Stock Option Agreements,
         rather than the Company, (ii) any and all outstanding options granted
         under such Stock Option Agreements shall be deemed to have granted
         shares of Common Stock, par value $.01 per share, of the Successor
         Company, rather than Common Shares, without par value, of the Company
         and (iii) such Stock Option Agreements conform, in all other respects
         necessary in the judgment of the appropriate officer or officers of
         Successor Company, to the purpose and intent of this paragraph (a); and

                  (b) effective as of immediately prior to the Effective Time,
         the Stock Option Agreements are hereby amended so that neither a tender
         offer nor a Control Share Acquisition, as defined in such Stock Option
         Agreements, shall be deemed to have occurred as a result of (i) the
         execution of the Merger Agreement or the Reorganization Agreement, (ii)
         the assignment by the Company to the Successor Company and the
         assumption by the Successor Company of all of the powers, authorities,
         duties, responsibilities and obligations of the Company with respect to
         the Plan and this Agreement, or (iii) the consummation of any other
         transaction contemplated in the Merger Agreement or the Reorganization
         Agreement; and such Stock Option Agreements are hereby further amended
         in order to conform, in all other respects necessary in the



                                       3

         judgment of the appropriate officer or officers of Successor Company,
         to the purpose and intent of this paragraph (b).

                  IN WITNESS WHEREOF, RPM, Inc., by officers duly authorized by
its Board of Directors, has caused this Amendment No. 3 to the RPM, Inc. 1989
Stock Option Plan to be signed this 14th day of October, 2002.
