RE: Extension to Post-Retirement Consulting Agreement
Dear Tom:
As you are aware, on June 1, 2005, you entered into a Post-Retirement Consulting
Agreement (the “Consulting Agreement”) with RPM International Inc. (“RPM” or the
“Company”). The Consulting Agreement provided that for the twenty-four
(24) month period (June 1, 2005 through May 31, 2007), you would utilize your
industry experience and business relationships to assist in corporate
development related activities including identifying acquisition opportunities,
as may be requested from time-to-time by the Company.
Whereas the Consulting Agreement is expiring and the Compensation Committee has
recognized that your services to the Company in the corporate development area,
particularly your work in identifying and introducing to the Company possible
merger and acquisition candidates and assisting in the consummation of such
transactions, have been very beneficial to the Company’s success. Therefore,
since the Committee further recognizes that retaining your continued services as
a consultant brings meaningful value to the Company and its stockholders, the
Company would like to extend the consulting period for an additional one year
period from June 1, 2007 to May 31, 2008 (the “Extension Period”). Given the
material benefits to RPM, the Company has agreed to the following compensation
and benefits and structure for the Extension Period:

1.   No Employment Relationship — As you are aware, you have not been an
employee of the Company since the date of your retirement on January 1, 2003.
Accordingly, you are not entitled to participate in the Company’s Benefit Plans,
except as required by law, the terms of the Benefit Plans, or as provided for
during the Extension Period (see below).

2.   Consulting Services – During the twelve (12) month Extension Period, the
Company will pay you a gross amount of $25,000 per month for your services as a
consultant. Specifically, you agree to continue to utilize your industry
experience and business relationships to assist in corporate development related
activities including identifying acquisition opportunities, as may be requested
from time-to-time by the Company. You also acknowledge that from time-to-time
you will be required to travel internationally in connection with the
performance of your consulting services. In addition, during the Extension
Period, you will also be entitled to the following benefits at the Company’s
sole cost and expense:

  a.   Use of reasonable off-site office space;     b.   Use of a part-time
administrative assistant;     c.   Continued use of your current company car;  
  d.   Continued coverage under the Company’s Health Insurance Plan for you and
your eligible dependent;     e.   Continued payment of the standard monthly
membership dues during the Extension Period for one country club, and the
membership dues for The Union Club; and     f.   Continuation of financial
planning services, as currently provided.

The Company believes the arrangements described above provide RPM and its
management team with continued access to your unique knowledge, insights,
experience and industry relationships. This letter constitutes the entire
agreement concerning this subject matter and supersedes all prior and
contemporaneous agreements, if any.
Sincerely yours,
RPM International Inc.
