                                     PART I

ITEM 1.           BUSINESS.

                                   THE COMPANY

                  RPM, Inc. ("RPM" or the "Company") was organized in 1947 as an
Ohio corporation under the name Republic Powdered Metals, Inc. On November 9,
1971, the Company's name was changed to RPM, Inc. As used herein, the terms
"RPM" and the "Company" refer to RPM, Inc. and its subsidiaries, unless the
context indicates otherwise. The Company has its principal executive offices at
2628 Pearl Road, P.O. Box 777, Medina, Ohio 44258, and its telephone number is
(330) 273-5090.

RECENT DEVELOPMENTS

                  In May 1998, the Company filed an application to list its
Common Shares for trading on the New York Stock Exchange ("NYSE"). On June 9,
1998, the Company's Common Shares began trading on the NYSE under the symbol
"RPM."

                  On July 8, 1998, the Company announced that all of the
outstanding $191.7 million principal amount of its Liquid Yield Option Notes Due
2012 ("LYONs(TM)") were called for redemption on August 10, 1998 pursuant to the
provisions of the Trust Indenture dated September 15, 1992 between the Company
and the First National Bank of Chicago, as Trustee and Paying Agent. As a result
of the redemption of these convertible securities, approximately 10.1 million
Common Shares were issued and LYONs(TM) holders who chose not to convert their
Notes to Common Shares received aggregate cash payments of $32.1 million.

ACQUISITIONS

                  Since RPM's offering of Common Shares to the public in
September 1969, the Company has made a number of significant acquisitions that
have been described in previous reports on file with the Securities and Exchange
Commission. RPM's acquisition strategy focuses on companies with high
performance and quality products which are leaders in their respective markets.
RPM expects to continue its acquisition program, although there is no assurance
that any acquisitions will be made.

                  As part of this acquisition program, in March 1998, the
Company acquired all of the issued and outstanding shares of The Flecto Company,
Inc. and its affiliated companies headquartered in Oakland, California. Flecto
is a leading manufacturer of wood finishes and wood finishing equipment for the
retail do-it-yourself wood and floor finishing markets in the United States and
Canada. Flecto sells clear and stain finishes under the Varathane(R) and
Watco(R) name brands.

<PAGE>   4
                  Subsequent to the May 31 fiscal year-end, on July 8, 1998, the
Company acquired Nullifire Ltd., based in Coventry, England. Nullifire is a
leading manufacturer and marketer of intumescent fireproofing coatings for
industrial and commercial applications. Nullifire will operate as part of the
Company's Carboline Company subsidiary, supplementing the product lines and
geographic coverage of Carboline's existing fireproofing business.


                                    BUSINESS

                  RPM operates principally in one business segment, the
manufacture and marketing of protective coatings. These protective coatings
products are used for both industrial and consumer applications. For industrial
applications, RPM manufactures and markets coatings for waterproofing and
general maintenance, corrosion control, and other specialty chemical
applications. For consumer applications, RPM manufactures do-it-yourself
products for the home maintenance, automotive repair, hobby and leisure and
marine markets. RPM, through its operating companies, serves niche markets
within these broader categories, thus providing a foundation for its strategy of
growth through product line extensions.

                  The protective coating products manufactured by RPM are used
primarily on property which already exists. RPM is not involved to any great
degree in new construction and, therefore, is generally less affected by
cyclical movements in the economy. RPM markets its products in approximately 130
countries and operates manufacturing facilities in 61 locations in the United
States, Argentina, Belgium, Brazil, Canada, China, Germany, Malaysia, The
Netherlands, Poland, Singapore, South Africa, the United Arab Emirates and the
United Kingdom.

INDUSTRIAL PRODUCTS

                  RPM's industrial products represent approximately 63% of the
Company's sales. The numerous protective coatings manufactured by the Company
are used in a variety of industrial applications including waterproofing,
general maintenance, corrosion control and other specialty chemical
applications.

                  The Company manufactures a number of products designed for
waterproofing applications. These waterproofing products include sealants, deck
coatings, membranes and water-based coatings for commercial and industrial
maintenance produced by the Company's Martin Mathys, ESPAN, and Tremco
businesses.

                  The Company also manufactures a variety of products used for
general commercial and industrial maintenance. These products include roofing
products, such as asphaltic aluminum roof deck coating produced by RPM's
original business unit, Republic Powdered Metals, Geoflex and Hy-Shield premium
single-ply roofing materials and Tremco roofing systems. Other products include
high-performance polymer floors, linings and wall systems produced by Stonhard,
molded and pultruded fiberglass reinforced plastic grating products manufactured
by Fibergrate Composite Structures, Inc. (formerly Composite Structures
International), under the brand names of Chemgrate and Fibergrate, as well as
Dryvit coatings and adhesives for exterior wall insulating finishing systems and
TCI powdered coatings.

                                       4
<PAGE>   5

                  The Company's industrial product line also includes a
broad-line of high-performance corrosion control coatings. The Company's
Carboline subsidiary manufactures high-performance corrosion-resistant
protective coatings, fireproofing, tank linings and floor coatings, and markets
these products to industrial, architectural and applicator companies throughout
the world. The Company's various other corrosion-resistant coatings include the
Plasite and Alox brands.

                  The Company also produces a variety of specialty chemical
products within selected niche markets. Products manufactured for specialty
chemical applications include: Day-Glo Color and Radiant Color fluorescent
colorants and pigments; Kop-Coat manufactured compounds and wood treatment
products including Wolman industrial lumber treatments and ValvTect diesel fuel
additives; American Emulsions dye additives for textile dyeing and finishing;
Chemspec commercial carpet cleaning solutions; and concrete admixtures sold by
The Euclid Chemical Company, RPM's 50-50 joint venture with the
Switzerland-based Holderbank Group.

CONSUMER PRODUCTS

                  RPM's consumer products represent approximately 37% of the
Company's sales. The Company's consumer products include products designed for
the household do-it-yourself, automotive repair, hobby and leisure and marine
markets.

                  RPM's primary consumer do-it-yourself businesses are
Rust-Oleum, William Zinsser, Bondex International and Bondo/Mar-Hyde. Rust-Oleum
manufactures high quality corrosion-resistant, general purpose and decorative
coatings for the household maintenance and light industrial markets. William
Zinsser manufactures a broad line of specialty primers and sealants and is the
nation's leading producer of shellac items used as pharmaceutical glazes,
confectioner's glazes, citrus fruit coatings and wood coatings. Bondex
International produces a nationwide line of household patch and repair products,
in addition to basement waterproofing products. Bondo/Mar-Hyde manufactures auto
body paints and repair products for the automotive aftermarket. Products
marketed by these units include spray paints, body fillers, vinyl colors and
bumper repair products.

                  The Company also manufactures products for the hobby and
leisure markets including Testor's model kits and accessory products and
Floquil/Polly S Color hobby, art and craft coatings. RPM's consumer hobby and
leisure products are marketed through thousands of mass merchandise, toy and
hobby stores throughout North America.

                  Other consumer do-it-yourself products include: fabrics,
window treatments and wall coverings sold by Design/Craft Fabric and Richard E.
Thibaut; Mohawk, Star Finishing and Chemical Coatings, and newly acquired Flecto
furniture finishes and repair and restoration coatings; pleasure marine coatings
marketed under the Pettit, Woolsey and Z-Spar brand names; and Wolman deck
coatings, sealants and brighteners. RPM's consumer do-it-yourself products are
marketed through thousands of mass merchandise, home center and hardware stores
throughout North America.

FOREIGN OPERATIONS

                  The Company's foreign manufacturing operations for the fiscal
year ended May 31, 1998 accounted for approximately 19% of its total sales
(which does not include exports directly from the United States), although it
also receives license fees and royalty income from numerous license agreements
and also has joint ventures accounted for under the equity method in various
foreign countries. The Company has manufacturing facilities in Argentina,
Belgium, Brazil, Canada, China, Germany, Malaysia, The Netherlands, Poland,
Singapore, South Africa, the United Arab Emirates and the United Kingdom, and
sales offices or public warehouse facilities in Australia, Canada, Finland,
France, Germany, Hong Kong, Iberia, Mexico, the Philippines, Russia, Singapore,
Sweden, the United Kingdom and several other countries. Information concerning
the Company's foreign operations is set forth in Note I (Industry Segment and
Geographic Area Information) of Notes to Consolidated Financial Statements,
which appear elsewhere in this Annual Report on Form 10-K.

COMPETITION

                  The Company is engaged in a highly competitive industry and,
with respect to all of its major products, faces competition from local and
national firms. Several of the companies with which RPM competes have greater
financial resources and sales organizations than the Company. While no accurate
figures are available with respect to the size of or the Company's position in
the market for any particular product, management believes that the Company is a
major producer of aluminum coatings, cement-based paint, hobby paints, pleasure
marine coatings, furniture finishing repair products, automotive repair
products, industrial corrosion control products, consumer rust-preventative
coatings, polymer flooring, fluorescent coatings and pigments, exterior
insulation finish systems, molded and pultruded fiberglass reinforced plastic
grating and shellac-based coatings. However, the Company does not believe that
it has a significant share of the total protective coatings market.

INTELLECTUAL PROPERTY

                  The intellectual property portfolios of the subsidiaries of
the Company include numerous valuable patents, trade secrets and know-how,
trademarks and trade names. Significant research and technology development
continues to be conducted by the subsidiaries. However, no single patent,
trademark, name or license, or group of these rights, other than the marks
Day-Glo(R), Rust-Oleum(R), Carboline(R) and Tremco(R), are material to the
Company's business.

                  Day-Glo Color Corp., a subsidiary of the Company, is the owner
of over 50 trademark registrations of the mark and name "DAY-GLO(R)" in numerous
countries and the United States for a variety of fluorescent products. There are
also many other foreign and domestic registrations for other trademarks of the
Day-Glo Color Corp., for a total of over 100 registrations. These registrations
are valid for a variety of terms ranging from one year to 20 years, which terms
are renewable as long as the marks continue to be used. Renewal of these
registrations is done on a regular basis.

                  Rust-Oleum Corporation, a subsidiary of the Company, is the
owner of over 50 United States trademark registrations for the mark and name
"RUST-OLEUM(R)" and other 


                                       6
<PAGE>   7

trademarks covering a variety of rust-preventative coatings sold by Rust-Oleum
Corporation. There are also many foreign registrations for "RUST-OLEUM(R)" and
the other trademarks of Rust-Oleum Corporation, for a total of nearly 400
registrations. These registrations are valid for a variety of terms ranging from
one year to 20 years, which terms are renewable for as long as the marks
continue to be used. Renewal of these registrations is done on a regular basis.

                  Carboline Company, a subsidiary of the Company, is the owner
of a United States trademark registration for the mark and name "CARBOLINE(R)."
Carboline Company is also the owner of several other United States registrations
for other trademarks. Renewal of these registrations is done on a regular basis.

                  Tremco Incorporated, a subsidiary of the Company, which was
acquired in February 1997, is the owner of over 100 registrations for the mark
and name "TREMCO(R)" in numerous countries and the United States for a variety
of sealants and coating products. There are also many other foreign and domestic
registrations for other trademarks of Tremco Incorporated, for a total of over
600 registrations and applications. The registrations are valid for a variety of
terms ranging from one year to 20 years, which terms are renewable as long as
the marks continue to be used. Renewal of the registration is done on a regular
basis.

                  The Company's other valuable product trademarks also include:
ALOX(R), ALUMANATION(R), AVALON(R), B-I-N(R), BITUMASTIC(R), BONDO(R),
BONDEX(R), BULLS EYE(R), CHEMGRATE(R), DRYVIT(R), DYMERIC(R), DYNALITE(R),
DYNATRON(R), EASY FINISH(R), FLECTO(R) EPOXSTEEL(R), FIBERGRATE(R), FLOQUIL(R),
GEOFLEX(R), LUBRASPIN(TM), MAR-HYDE(R), MOHAWK and DESIGN(R), OUTSULATION(R),
PARASEAL(R), PERMAROOF(R), PETTIT(TM), PLASITE(R), SANITILE(R), STONCLAD(R),
STONHARD(R), STONLUX(R), TALSOL(R), TCI(TM), TESTORS(R), ULTRALITE(TM),
VARATHANE(R), VULKEM(R), WOOLSEY(R), ZINSSER(R) and Z-SPAR(R); and, in Europe,
NULLIFIRE(R), RADGLO(R) and MARTIN MATHYS(R).

RAW MATERIALS

                  The Company believes that alternate sources of supply of raw
materials are available to the Company for most of its raw materials. Where
shortages of raw materials have occurred, the Company has been able to
reformulate products to use more readily available raw materials. Although the
Company has been able to reformulate products to use more readily available raw
materials in the past, there can be no assurance as to the Company's ability to
do so in the future.

SEASONAL FACTORS

                  The Company's business is seasonal due to outside weather
factors. The Company historically experiences strong sales and income in its
first, second and fourth fiscal quarters comprised of the three month periods
ending August 31, November 30 and May 31, respectively, with weaker performance
in its third fiscal quarter (December through February).





                                       7
<PAGE>   8

CUSTOMERS

                  No one customer accounted for 10% or more of the Company's
total sales. The Company's business is not dependent upon any one customer or
small group of customers and is dispersed over thousands of customers.

BACKLOG

                  The Company historically has not had a significant backlog of
orders, nor was there a significant backlog during the last fiscal year.

RESEARCH

                  The Company's research and development work is performed in
various laboratory locations throughout the United States. During fiscal years
1998, 1997 and 1996, the Company invested approximately $15.8 million, $14.6
million and $13.7 million, respectively, on research and development activities.
The customer sponsored portion of such expenditures was not significant.

ENVIRONMENTAL MATTERS

                  Several of the Company's subsidiaries are involved in various
environmental claims or proceedings relating to facilities currently or
previously owned, operated or used by such subsidiaries, or their predecessors.
In addition, the Company or its subsidiaries, together with other parties, have
been designated as potentially responsible parties ("PRPs") under federal and
state environmental laws for the remediation of hazardous waste at certain
disposal sites (see ITEM 3. LEGAL PROCEEDINGS). In connection with its
evaluation of these PRP sites, the Company's management takes into consideration
the input of outside legal counsel, the number of parties involved at the site,
joint and several liability of other PRPs, and the level of volumetric
contribution which may be attributed to the Company relative to that
attributable to other parties at such sites. Based on the above analysis,
management then assesses, to the extent possible, the estimated restoration or
other clean-up costs and related claims for each site.

                The Company's environmental-related accruals are established
and/or adjusted as information becomes available upon which more accurate costs
can be reasonably estimated. Actual costs may vary from these estimates due to
the inherent uncertainties involved. In management's opinion, based upon
information presently available, the outcome of these environmental matters
will not have a material adverse effect on the Company's financial position,
results of operations or liquidity. However, such costs could be material to
results of operations in a future period.

EMPLOYEES

                  As of June 30, 1998, the Company employed 6,926 persons, of
whom 788 were represented by unions under contracts which expire at varying
times in the future. The Company believes that its relations with its employees
are good.

ITEM 2.           PROPERTIES.

                  The Company's corporate headquarters and a plant and offices
for one subsidiary are located on an 80-acre site in Medina, Ohio, which is
owned by the Company. The Company has agreed to purchase an additional 39 acres
adjacent to the 80-acre site from the Estate of Margaret M. Sullivan, the mother
of Thomas C. Sullivan, Chairman and Chief Executive Officer of the Company. The
Company's operations occupy a total of approximately 6.1 million square feet,
with the majority, approximately 5.1 million square feet, devoted to
manufacturing, assembly and storage. Of the approximately 6.1 million square
feet occupied, 5.0 million square feet are owned and 1.1 million square feet are
occupied under operating leases.

                  For information concerning the Company's rental obligations,
see Note E (Leases) of Notes to Consolidated Financial Statements, which appear
elsewhere in this Annual Report on Form 10-K. Under all of its leases, the
Company is obligated to pay certain varying insurance costs, utilities, real
property taxes and other costs and expenses.

                  The Company believes that its manufacturing plants and office
facilities are well maintained and suitable for the operations of the Company.

ITEM 3.           LEGAL PROCEEDINGS.

                  Bondex.
                  -------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, and as updated in the Company's
Quarterly Reports on Form 10-Q for the quarters ended August 31, 1997, November
30, 1997 and February 28, 1998, Bondex International, Inc., a wholly-owned
subsidiary of the Company ("Bondex"), was one of numerous corporate defendants
in 387 then pending asbestos-related bodily injury lawsuits filed on behalf of
various individuals in various jurisdictions of the United States. Subsequently,
an additional 5 such cases have been filed and 2 such cases which had been filed
were dismissed with prejudice without payment pursuant to summary judgment or
stipulation of the parties, leaving a total of 390 such cases pending. Bondex
continues to deny liability in all asbestos-related lawsuits and continues to
vigorously defend them. Under a cost-sharing agreement among Bondex and its
insurers effected in 1994, the insurers are responsible for payment of a
substantial portion of defense costs and indemnity payments, if any, with Bondex
responsible for a minor portion of each.

                  Carboline.
                  ----------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, Carboline Company, a wholly-owned
subsidiary of the Company ("Carboline") has been named as one of 30 corporate
defendants in Rufino O. Cavazos, et al., vs. Ceilcote Company, et al., Cause No.
89-CI-12651, in the 73rd Judicial District Court of Bexar County, Texas, filed
in March 1990, and in similar suits subsequently filed on behalf of individuals
(and, where applicable, their spouses and children) employed at the Comanche
Peak Nuclear Plant and the South Texas Nuclear Plant. The total number of Bexar
County plaintiffs is approximately 10,000. The trial court has entered a
scheduling order which calls for summary judgment hearings in November 1998.
Carboline, and all other defendants, have sought summary judgment on the


                                       9
<PAGE>   10

grounds that Plaintiffs cannot prove a causal connection between their alleged
exposures at the power plants and their alleged physical ailments. Depending on
the results of the summary judgment hearings, summary jury trials, involving
approximately 20 plaintiffs, are anticipated in 1999. Another suit with
virtually identical allegations was filed on December 29, 1993 in Rusk County,
Texas, which involves 155 worker plaintiffs and 82 spouses. All of the suits
allege bodily injury as a result of exposure to defendants' products. The
litigation is continuing in the discovery stage. With respect to the Bexar
County cases, the court has indicated that summary jury trials involving 10
plaintiffs each will be scheduled, although specific trial dates have not been
set. Carboline has denied all liability in these cases and is conducting a
vigorous defense. Several of Carboline's insurance carriers, and Carboline, are
defending the lawsuits under a cost-sharing agreement.

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, in September 1991, Our Lady of the
Lake Hospital, Inc. ("OLOL") filed suit captioned Our Lady of the Lake Hospital,
Inc. vs. Carboline Company, et al, Number 373,498, Division "J", Nineteenth
Judicial District Court, Parish of East Baton Rouge, State of Louisiana,
alleging that a fireproofing product manufactured by Carboline, known as
Pyrocrete 102, caused damage to the structural steel of the hospital which OLOL
owns and operates in Baton Rouge, Louisiana.

                  Carboline denied the allegations of both OLOL's claims and
vigorously contested them. Carboline's defense was assumed by First Colonial
Insurance Company ("First Colonial"), a wholly-owned insurance subsidiary of the
Company. As previously reported, on July 10, 1996, OLOL, Carboline and Sun
entered into a confidential Settlement Agreement with respect to all claims and
disputes presented in, arising out of, or relating in any way to the claims
filed by OLOL in Case Numbers 373,498; 384,867; and 395,932. OLOL's petitions,
as supplemented and amended, were dismissed with prejudice. Carboline has
entered into confidential settlements with a number of its insurers which funded
the settlement and who have been or will be dismissed from the litigation.
Carboline's third party claims against certain non-settling insurers and other
parties remain pending in Case Number 373,498. Carboline is currently engaged in
settlement negotiations with the remaining third party defendants.

                  As previously reported, Carboline is a defendant in La Gloria
Oil & Gas Company vs. Carboline Company, et al., Cause No. 95-959-C, in the
241st Judicial District Court of Smith County, Texas. The plaintiff, an owner
and operator of a petroleum refinery in Tyler, Texas, contends that a
fireproofing product previously designed and manufactured by Carboline is
defective and that the product resulted in deterioration and corrosion of
various steel components at the refinery. Additionally, the plaintiff alleges
fraud and civil conspiracy and seeks $25 million in actual damages and up to
four times the amount of actual damages in exemplary damages against Carboline
and Sun, as well as co-defendant Brown & Root, Inc. The case is in the discovery
phase, and is set for trial in early 1999. Pursuant to an agreement between
Carboline and Sun, Carboline is providing a defense for Sun in this litigation.

                  Carboline has denied all of plaintiff's allegations and is
vigorously defending the lawsuit. Carboline contends that based upon applicable
statutes of limitations, plaintiff's claims are time-barred. Although there has
been diminishment of insurance policy limits available to Carboline as a result
of the previously referenced settlement, the Company believes that the


                                       10

ultimate resolution of this matter will not have a material adverse effect on
the Company's financial position or results of operations.

                  Mac-O-Lac.
                  ----------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, the Company has been identified as
a PRP under CERCLA in connection with the Rose Township Dump Site, Rose
Township, Michigan (the "Rose Township Site") and the Springfield Township Dump
Site, Springfield Township, Michigan (the "Springfield Site") as a consequence
of the disposal of waste originating at Mac-O-Lac Paints, Inc., a former
subsidiary of the Company whose assets were sold in February 1982.

                  With respect to the Rose Township Site, the Company and eleven
other PRPs signed a Consent Decree which, on July 18, 1989, was entered by the
Court in United States of America vs. AKZO Coatings of America, Inc. et al.,
U.S. District Court, Eastern District of Michigan, Southern Division; Civil
Action No. 88-CV-73784-DT. Pursuant to the agreement, the PRPs established a $9
million fund to cover costs of remediation, of which the Company's share,
$300,000, has been paid.

                  With respect to the Springfield Site, the Company and other
PRPs engaged in negotiations with the EPA and the Michigan Department of Natural
Resources in an effort to reach agreement on mutually acceptable remediation
parameters and have negotiated Administrative Orders on Consent Regarding
Selected Response Activities and for Cost Recovery Settlement.

                  Dryvit.
                  -------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, as updated in the Company's
Quarterly Reports on Form 10-Q for the quarters ended August 31, 1997, November
30, 1997 and February 28, 1998, Dryvit Systems, Inc., a wholly-owned subsidiary
of the Company ("Dryvit"), is a defendant or co-defendant in numerous separate
but related law suits, some of which have sought to certify classes comprised of
owners of structures clad with exterior insulated finish systems ("EIFS")
products manufactured by Dryvit and other EIFS manufacturers. Also as previously
reported, on September 18, 1996, the North Carolina Court presiding over one of
the state court cases, Ruff et al. v. Parex, Inc., et al., entered an order
certifying a class of North Carolina owners of single family or multi-family
residential dwellings which had an EIFS installed during the period of 1969 to
the present. Subsequent to that ruling, Dryvit and other manufacturers filed a
motion to bring a third-party complaint against the builders of those dwellings
to establish that any alleged damage was the result of poor construction. The
trial court denied that motion but acknowledged that the manufacturers were
being denied significant rights since claims against builders for indemnity
and/or contribution were possibly being extinguished by the running of the
statutes of repose and/or statute of limitations. Dryvit and several other
manufacturers' appealed the trial court's decision. The Appellate Court has
agreed to review the manufacturers' appeal and issued a Writ of Prohibition
effectively staying the trial court action. The Appellate decision is expected
by the end of the 1998 calendar year.



                                       11
<PAGE>   12

                  Also as previously reported, on August 11, 1997, Judge Britt
of the U.S. District Court for the Eastern District of North Carolina, issued an
order in the multi-district litigation proceeding styled In Re Stucco Litigation
denying plaintiffs' attempts to certify a national class comprised of owners of
single family and multi-family residences clad with EIFS. Judge Britt's opinion
cited, inter alia, the role of various third parties, including builders,
contractors, architects, subcontractors and window manufacturers, as it relates
to liability, causation and comparative fault determinations as well as
contribution and indemnity considerations.

                  One of Dryvit's co-defendants in Ruff, Senergy, Inc. and its
affiliate Thoro ("Senergy"), has entered into a tentative settlement agreement
with plaintiffs. The agreement, which has not been approved by the court,
contemplates the certification, for settlement purposes only, of a nationwide
class comprised of owners of single and multi-family residences clad with a
Senergy EIFS and the establishment of a settlement fund to cover eligible repair
claims. The settlement has received preliminary approval by the court and a
formal fairness hearing is scheduled for September 11, 1998. The Senergy
settlement is not expected to prejudice Dryvit's defense of the Ruff case or its
arguments on appeal.

                  There have been two attempted state class actions filed in
Georgia. The first filed, Hardy, et al v. Dryvit Systems, Inc. et al, seeks to
certify a class comprised of owners of single family and multi-family residences
clad with EIFS constructed since 1969. Oral argument for class certification is
scheduled for September 22, 1998. Dryvit and the other EIFS manufacturers have
filed third party complaints against various third parties which underscores the
inappropriateness of this case for class certification. If the court does
certify a class action against the EIFS manufacturers, the manufacturers will
ask the court to certify a class of defendants comprised of builders,
sub-contractors and window manufacturers. Based on the presence of third parties
and Judge Britt's decision in In Re Stucco, the EIFS manufacturers are confident
class certification will be defeated.

                  The other attempted class action in Georgia, Stein v. Dryvit
Systems, Inc. seeks to certify a class comprised of owners of all structures
(both residential and commercial) clad with a Dryvit EIFS constructed since
1969. Dryvit has attempted to remove the case to federal court under Judge Britt
as part of the MDL proceeding. Since Judge Britt has already denied an attempted
national class in In Re Stucco Litigation, and those same issues are present in
Stein, Dryvit is confident that if the case remains in federal court, Judge
Britt would deny class certification.

                  Dryvit was recently named as a defendant in three additional
attempted state class actions relating to EIFS including two virtually identical
class action cases filed in Alabama. The Alabama cases seek to certify a class
comprised of all owners of single family and multi-family residences completed
since 1969 and a class comprised of builders and other third-parties. The other
attempted class action filed in Texas seeks to establish a class comprised of
owners of all types of structures clad with EIFS since 1969. Dryvit intends to
vigorously contest class certification and liability in all three cases.

                  Dryvit and other parties (contractors, architects,
distributors, EIFS applicators, roofers, sealant suppliers, sealant contractors
and window manufacturers) have been named in approximately 200 additional
homeowner lawsuits. The overwhelming majority of these suits


                                       12
<PAGE>   13

have been filed in North Carolina by individual homeowners who either have opted
out of the Ruff class action or have filed complaints against their builder,
which then brings a third-party action against Dryvit. The two other states with
the largest number of homeowner lawsuits are Alabama and South Carolina.

                  Dryvit's insurers, excluding First Colonial Insurance Company,
the Company's wholly-owned subsidiary ("First Colonial"), are currently paying
Dryvit's defense costs in the class actions and the individual lawsuits
involving structures that were built during or prior to their insurance coverage
periods. In addition, these insurance carriers have been regularly funding
settlement of these individual homeowner cases when appropriate. In the fiscal
year ending May 31, 1998, Dryvit's insurance carriers funded the settlement of
over 40 cases. Dryvit and its insurance carriers, including First Colonial, are
parties to three declaratory judgment actions pending in Rhode Island, New York
and California. The Rhode Island and New York actions have been stayed in favor
of the more complete and earlier filed California action. Dryvit was recently
awarded summary judgment on the issue of defense costs against one of its
insurers. The trial court ruled that there was a duty to defend Dryvit in the
class action litigation and related matters. Dryvit firmly believes that the
damages being sought by the plaintiffs' in the EIFS litigation are covered under
existing insurance policies and that it has adequate insurance coverage. The
Company believes that the ultimate resolution of these cases will not have a
material adverse effect on the Company's financial position or results of
operations.

                  Mohawk and Westfield.
                  ---------------------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, Mohawk Finishing Products, Inc.
("Mohawk") and Westfield Coatings Corporation ("Westfield"), both wholly-owned
subsidiaries of the Company, were notified by the EPA of their status as PRPs
under CERCLA with respect to environmental contamination at the Solvents
Recovery of New England Site (the "SRS Site") located in Southington,
Connecticut. Since June 1992, the EPA has notified approximately 1,300 entities
as PRPs in connection with the SRS Site. The EPA alleges Mohawk and Westfield
have contributed 459,570 gallons of hazardous substances out of the
approximately 51,383,013 gallons identified as having been shipped by non-
deminimus PRPs. The PRPs have not as yet agreed to any final allocation formula,
whether based on volume or otherwise. The EPA has completed an early de minimis
settlement with almost 1,000 PRPs who had sent less than 10,000 gallons to the
SRS Site. Neither Mohawk nor Westfield qualified for that settlement. To date,
the EPA and the State of Connecticut have expended in excess of $5 million in
connection with the SRS Site but the EPA has not yet selected the final remedial
action. Several hundred PRPs, including Mohawk and Westfield, have consented to
administrative orders to perform non-time critical removal actions to contain
contaminated water in the aquifer at the SRS Site and to perform both the
Remedial Investigation and Feasibility Study. It is not possible at this time to
determine whether Mohawk and Westfield will be eligible to participate in any
subsequent de-minimus settlement nor is it possible to quantify what, if any,
liability share these companies may have for further remediation.

                  In January 1994, the EPA notified Westfield of its status as
one of approximately 300 PRPs at the Old Southington Landfill Superfund Site
(the "Landfill") on the basis that process wastes from the SRS Site were sent to
the Landfill prior to October 1967. In September 1994, the EPA issued a Record
of Decision which selected a source control remedy that consisted of


                                       13
<PAGE>   14

installation of a cap on the Landfill together with a gas collection system at
an estimated cost of $16.1 million. The EPA has deferred to a second operable
unit the issue of whether to actively remediate groundwater at the Landfill, but
is insisting that certain groundwater studies be performed which will likely
cost several million dollars. Westfield recently entered into a consent decree
with the United States and the State of Connecticut which resolves the Company's
liability for the First Operable Unit. Upon entry of the consent decree by the
federal district court in Connecticut, Westfield will be obligated to contribute
$26,476.21 to settle its liability for the First Operable Unit. It is expected
that additional settlement discussions between the PRPs and the United States
and the State of Connecticut will commence later in the summer in an effort to
try to settle the remaining issues at OSL. It is not possible at present to
determine what, if any, liability share of the remaining response costs at OSL
might be assigned to Westfield.

                  The Company believes that the ultimate resolution of the SRS
Site and the Landfill matters will not have a material adverse effect on the
Company's financial position or results of operations.

                  Rust-Oleum.
                  -----------

                  As previously reported in the Company's Annual Report on Form
10-K for the fiscal year ended May 31, 1997, in November 1979, the EPA commenced
an action captioned United States of America vs. Midwest Solvent Recovery, Inc.,
et al.; United States District Court for the Northern District of Indiana,
Eastern Division; Civil No. H-79-556, pertaining to pollution allegedly
occurring at and around real property located at 7400 West Fifteenth Street,
Gary, Indiana ("MIDCO I") and 5900 Industrial Highway, Gary, Indiana ("MIDCO
II") (collectively, the "MIDCO Sites"). The Complaint was subsequently amended
in January 1984 to join Rust-Oleum Corporation, a wholly-owned subsidiary of the
Company ("Rust-Oleum"), and other entities as additional defendants. Rust-Oleum,
one of approximately 130 identified PRPs, is alleged to be associated with the
MIDCO Sites as a consequence of disposal of waste originating at its former
Evanston, Illinois plant in the mid-1970's. The Court approved a Consent Decree
in June 1992 under which Rust-Oleum entered into a Settlement Agreement with the
other settling PRPs for the voluntary cleanup of the MIDCO Sites consistent with
the EPA Record of Decision. All surface hazardous wastes have been removed from
the MIDCO Sites and cleanup is now in the groundwater remediation stage.
Remediation should be complete by the year 2002, with monitoring continuing for
an undetermined period. Total remediation and monitoring costs are currently
estimated to be $35 million. Included in the Consent Decree is an Agreement
between the Settling PRPs, including Rust-Oleum, and third parties who had been
sued for contribution by the generator PRPs, providing for payment by the third
parties of their fair share of the MIDCO Sites remedial and response costs.
Third party funds have been placed into the MIDCO Trust Fund, which has been
created to fund the MIDCO Site remedial actions. Rust-Oleum, as a settling PRP,
has provided financial assurance for its share of the cleanup costs in the form
of a Letter of Credit.

                  In March 1988, the EPA named Rust-Oleum and 240 other entities
as PRPs under CERCLA in connection with the Ninth Avenue Site at 7537 Ninth
Avenue, Gary, Indiana (the "Ninth Avenue Site"). Rust-Oleum is alleged to be
associated with the Ninth Avenue Site as a consequence of disposal of waste
originating at its former Evanston, Illinois plant in the 1970's. Rust-Oleum has
cooperated with over twenty other PRPs in a voluntary cleanup under Phase I and
Phase II Participation Agreements and Implementation Trust Agreements. Total
Ninth Avenue Site 


                                       14
<PAGE>   15

remediation and monitoring costs are estimated to be approximately $36 million,
including past costs and the Final Site Remedy, which includes groundwater
remediation planned for completion by 1997 and ongoing monitoring for an
undetermined period. The EPA issued an Amended Record of Decision on September
13, 1994 regarding the Final Site Remedy and an Amended Unilateral
Administrative Order to Rust-Oleum and the other participating PRPs on December
27, 1994 to undertake the Final Site Remedy. Rust-Oleum and eighteen other PRPs
have entered into a Final Participation Agreement for Final Remedial Action at
the Ninth Avenue Site. Rust-Oleum's allocation of cost is currently 6.048%, with
approximately $170,000 remaining to be paid subject, however, to reduction to
the extent settlements are made with non-participating PRPs and funds are made
available from a Trust Fund established by the EPA for de minimis settlors.
Rust-Oleum has provided financial assurance for its share of the Final Site
Remedy in the form of a Letter of Credit.

                  Based upon prior settlement agreements with insurance carriers
for potential costs and remediation liabilities in connection with the MIDCO
Sites and the Ninth Avenue Site, Rust-Oleum has established appropriate reserves
to cover such costs and liabilities. Accordingly, the Company believes that
ultimate resolution of these matters will not have a material adverse effect on
the Company's financial position or results of operations.

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Debentures"), issued and to be issued in a single
series under an Indenture, dated as of June 1, 1995 as supplemented by the First
Supplemental Indenture dated as of March 5, 1998 (herein called the "Indenture",
which term shall have the meaning assigned to it in such instrument), between
the Company and The First National Bank of Chicago, as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
and reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Debentures and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. This Debenture is
one of the series designated on the face hereof, limited in aggregate principal
amount to $100,000,000.

         RPM, INC., a corporation duly organized and existing under the laws of
the State of Ohio (herein called the "Company", which term includes any
successor Person under the Indenture hereafter referred to), for value received,
hereby promises to pay to CEDE & CO., or registered assigns, the principal sum
of One Hundred Million and No/100 Dollars ($100,000,000) on March 1, 2008, and
to pay interest thereon from the Original Issuance Date or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on each March 1 and September 1 (each an "Interest
Payment Date"), determined as set forth herein, commencing September 1, 1998, at
the rate of interest determined as set forth herein, until the principal hereof
is paid or made available for payment. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Debenture (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be one Business Day prior to the
relevant Interest Payment Date (except that if the Debentures are no longer
represented by a global Security as a result of the occurrence of an event
specified in Section 305(a) of the Indenture, the Regular Record Date for such
interest payment shall be the close of business on the fifteenth day (whether or
not a Business Day), as the case may be, next preceding such Interest Payment
Date). In the event that any date on which interest is payable on the Debentures
is not a Business Day, then payment of the interest payable on such date will be
made on the next succeeding day which is a Business Day (without any interest or
other payment in respect of any such delay). Any such interest not so punctually
paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this
Debenture (or one or more 

<PAGE>   3

Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Debentures not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Debentures may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Debenture will be made at the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register.

         Except as provided above with respect to the payment of interest, any
payment on this Debenture due on any day which is not a Business Day in the City
of New York need not be made on such day, but may be made on the next succeeding
Business Day with the same force and effect as if made on the due date and no
interest shall accrue for the period from and after such date.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to herein by manual signature, this Debenture shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

         During any Floating Rate Period (as defined below), interest on this
Debenture shall be payable semi-annually in arrears on each Interest Payment
Date, commencing on September 1, 1998, at the applicable Floating Rate (as
defined below), determined and compounded on a quarterly basis or determined but
not compounded from time to time on a semiannual basis, as applicable. During
any Fixed Rate Period (as defined below), interest on this Debenture shall be
payable semi-annually in arrears on each Interest Payment Date at the Fixed Rate
(as defined below). Interest, whether accruing at a Floating Rate or the Fixed
Rate, will accrue from and including the Original Issuance Date or, if later,
from and including the most recent Interest Payment Date on which interest has
been paid or duly provided for. Interest on this Debenture calculated at a
Floating Rate for any period shall be computed on the basis of the actual number
of days elapsed in such period and a 360-day year. Interest on this Debenture
calculated at the Fixed Rate for any period shall be computed on the basis of a
360-day year of twelve 30-day months and, for any period shorter than a full
semi-annual Interest Accrual Period for which interest is computed, on the basis
of the actual number of days elapsed in such period.

As used herein:

"Business Day" means any day, other than a Saturday or Sunday, or a day on which
banking institutions in New York, New York are authorized or obligated by law or
executive order to be closed.

"Calculation Agent" means the Swap Counterparty as calculation agent, and its
successors in such capacity under the Swap Agreement.

"Final Maturity Date" means March 1, 2008.

"Fixed Rate" means 6.50% per annum.

"Fixed Rate Period" exists at any time until the Final Maturity Date at which a
Floating Rate Period is not in effect.

"Floating Rate" means, (i) for any Interest Accrual Period during the Initial
Floating Rate Period, a rate per annum equal to the London interbank offered
rate for United States dollar deposits ("LIBOR") for a period of six months
minus .05% (the "Initial Floating Rate") and (ii) for any Interest Accrual
Period during the Subsequent Floating Rate Period, a rate per annum equal to
LIBOR for a period of three months (the "Subsequent Floating Rate"). Each such
Floating Rate shall be determined from time to time on the Interest
Determination Date during such Interest Accrual Period by the Calculation Agent
in accordance with the following provisions (in each case, with all percentages
resulting from any calculation rounded to the nearest one hundred-thousandth of
a percent, with five one-millionths of a percent rounded upward; and all dollar
amounts used in or resulting from any such calculation will be rounded to the
nearest cent, with one-half cent rounded upward):

                  (i) For each applicable semiannual or quarterly period, LIBOR
will be determined on the basis of the offered rates for deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, commencing on
the first day of such period immediately following the related Interest
Determination Date, which appear on Telerate Page 3750 on the Dow Jones Telerate
Service (or such other page as may replace that page on that service for the
purpose of displaying London interbank offered rates of major banks) as of 11:00
a.m. (London time) on that Interest Determination Date. If such rate does not so
appear on Telerate Page 3750, LIBOR in respect of such Interest Determination
Date will be determined as described in (ii) below.

                  (ii) If on any applicable Interest Determination Date the rate
for deposits of U.S. dollars having a six-month or three-month maturity, as
applicable, does not appear on Telerate Page 3750 as specified in (i) above,
LIBOR will be determined on the basis of the rates at which deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, are offered
by major banks selected by the Calculation Agent in the London interbank market
at approximately 11:00 a.m. (London time) on the related Interest Determination
Date to prime banks in the London interbank market for a period commencing on
the first day of such period immediately following that Interest Determination
Date and in a principal amount of not less than $1 million that in the
Calculation Agent's judgment is representative for a single transaction in such
market at such time. The Calculation Agent will request the principal London
office of each such bank to provide a quotation of its rate. If at least two
such quotations are provided, LIBOR in respect of that Interest Determination
Date will be the arithmetic mean of such quotations. If fewer than two
quotations are provided, LIBOR in respect of that Interest

<PAGE>   5

Determination Date will be the arithmetic mean of the rates quoted by major
banks in New York City selected by the Calculation Agent at approximately 11:00
a.m. (New York City time) on that Interest Determination Date for loans in U.S.
dollars to leading European banks, having a six-month or three-month maturity,
as applicable, commencing on the first day of such Interest Accrual Period
immediately following that Interest Determination Date and in a principal amount
of not less than $1 million that, in the Calculation Agent's judgment, is
representative for a single transaction in such market at such time.

         The Calculation Agent's determination of any interest rate will be
final and binding in the absence of manifest error.

         "Floating Rate Period" means (i) the period from the Original Issuance
Date until the Interest Rate Reset Date (the "Initial Floating Rate Period") and
(ii) after the Initial Floating Rate Period, the period from the Interest Rate
Conversion Date until the Final Maturity Date (the "Subsequent Floating Rate
Period"). Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date (if any) and the election by Holders of not less than 66(% in
aggregate principal amount of the Debentures, (A) any Floating Rate Period then
in effect shall automatically terminate and a Fixed Rate Period shall
automatically be in effect, (B) a Fixed Rate Period shall automatically be in

         Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date, if the Debentures shall then bear interest at a Floating Rate,
the Holders of not less than 66-2/3% in aggregate principal amount of the
Debentures will have the right to elect to convert the interest rate on all, but
not less than all, of the Debentures from such Floating Rate to the Fixed Rate
by delivering to the Company and the Trustee irrevocable written notice of such
Holders' election to so convert the interest rate. Such notice to the Company
and the Trustee shall set forth the name of the Holders exercising such right
and a statement that a Swap Termination Date has occurred and that the Holders
wish to exercise their right to convert the interest rate to the Fixed Rate
pursuant to this Section. Any exercise of such conversion right shall be
irrevocable. Upon receipt of such notice by the Company, (i) any Floating Rate
Period then in effect shall terminate, (ii) a Fixed Rate Period will then be in
effect and be deemed to have been in effect at all times from the then most
recent Interest Payment Date on which interest has been paid or duly provided
for (or, if no interest has been paid or duly provided for on any Interest
Payment Date, the Original Issuance Date) and (iii) no Floating Rate Period
shall thereafter be in effect at any time.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Debenture or certain restrictive covenants and
Events of Default with respect to this Debenture upon compliance with certain
conditions set forth in the Indenture.

         The Debentures are not subject to redemption at the option of the
Company or any Holder prior to maturity and will not be subject to any sinking
fund.

         If an Event of Default with respect to the Debentures shall occur and
be continuing, the principal of the Debentures may be declared due and payable
in the manner and with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Debentures at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of a majority in the principal amount of the
Debentures of each series at the time Outstanding, on behalf of the Holders of
all the Debentures of such series, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Debenture shall be conclusive and binding upon such Holder and upon all
future Holders of this Debenture and of any Debenture issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Debenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Debenture shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with

<PAGE>   8

respect to the Debentures, the Holders of not less than 25% in principal amount
of the Debentures at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonably satisfactory indemnity, and the Trustee shall
not have received from the Holders of a majority in principal amount of the
Debentures at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Debenture for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Debenture at the times, place and rate, and in the coin and
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Debenture is registrable in the Security
Register, upon surrender of this Debenture for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Debenture are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Debentures
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         The Debentures are issuable only in registered form without coupons in
denominations of $100,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Debentures
are exchangeable for a like aggregate principal amount of Debentures and of like
tenor of a different authorized denomination, as requested by the Holder
surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this Debenture which are defined in the Indenture

Inc., a corporation duly organized and existing under the laws of the State of
Ohio (herein called the "Company"), having its principal office at 2628 Pearl

banking association duly organized and existing under the laws of the United
States, as Trustee (herein called the "Trustee") under the Indenture dated as of
June 1, 1995 between the Company and the Trustee (the "Indenture").

                             Recitals of the Company

         The Company has executed and delivered the Indenture to the Trustee to
provide for the issuance from time to time of its unsecured debentures, notes or
other evidences of indebtedness (the "Securities"), to be issued in one or more
series as provided in the Indenture.

         Pursuant to the terms of the Indenture, the Company desires to provide
for the establishment of a new series of its Securities to be known as its
"Liquid Asset Notes with Coupon Exchange ("LANCEs(SM)") Due 2008" (herein called
the "Debentures"), in this First Supplemental Indenture.

         All things necessary to make this First Supplemental Indenture a valid
agreement of the Company have been done.

                  Now, Therefore, This First Supplemental Indenture Witnesseth:

         For and in consideration of the premises and the purchase of the
Debentures by the Holders thereof, it is mutually agreed, for the equal and
proportionate benefit of all Holders of the Debentures, as follows:

                                   ARTICLE ONE
                             Terms of the Debentures

         Section 101. There is hereby authorized a series of Securities
designated the "Liquid Asset Notes with Coupon Exchange ("LANCEs(SM)") Due 
2008", limited in aggregate principal amount to $100,000,000 (except as
provided in Section 301(2) of the Indenture). The Debentures shall mature and
the principal shall be due and payable together with all accrued and unpaid
interest thereon on March 1, 2008 and shall be issued in the form of a
registered global Security without coupons, registered in the name of Cede
& Co.

         Section 102. The Debentures shall be issued in global form and the
provisions of Sections 201, 203 and 305 of the Indenture applicable to global
Securities shall apply to the Debentures.

         Section 103. (a) Interest Rates. During any Floating Rate Period (as
defined below), interest on each of the Debentures shall be payable
semi-annually in arrears on each March 1 and September 1 (each an "Interest
Payment Date"), commencing on September 1, 1998, at the applicable Floating Rate
(as defined below), determined and compounded on a quarterly basis or determined
but not compounded on a semiannual basis, as applicable. During any Fixed Rate
Period (as defined below), interest on each of the Debentures shall be payable
semi-annually in arrears on each Interest Payment Date at the Fixed Rate (as
defined below). Interest, whether accruing at a Floating Rate or the Fixed Rate,
will accrue from and including the Original Issuance Date or, if later, from and
including the most recent Interest Payment Date on which interest has been paid
or duly provided for. Interest on the Debentures calculated at a Floating 


<PAGE>   3



Rate for any period shall be computed on the basis of the actual number of days
elapsed in such period and a 360-day year. Interest on the Debentures calculated
at the Fixed Rate for any period shall be computed on the basis of a 360-day
year of twelve 30-day months and, for any period shorter than a full semi-annual
Interest Accrual Period for which interest is computed, on the basis of the
actual number of days elapsed in such period.

         (b) Interest Rate Conversion. Effective on the Interest Rate Reset Date
or on any anniversary thereof to and including March 1, 2007 or if such date is
not a Business Day, then on the following Business Day (each, a "Reference
Date"), if a Swap Termination Date shall not have occurred by such date and the
Swap Rate (as defined below) for an interest rate swap with a remaining maturity
(as set forth below, the "Remaining Maturity") corresponding to the applicable
Reference Date is greater than or equal to the applicable reference rate (as set
forth below, the "Reference Rate"), then the interest rate on all, but not less
than all, of the Debentures shall be converted from the Fixed Rate to the
Subsequent Floating Rate for each subsequent Interest Accrual Period (in
accordance with the definition of Floating Rate Period) (the "Interest Rate
Conversion"). From and after the date of the Interest Rate Conversion (the
"Interest Rate Conversion Date") and for each Interest Accrual Period ending
prior to the end of the Floating Rate Period which begins on such Interest Rate
Conversion Date, interest on all of the Debentures shall accrue at the
Subsequent Floating Rate. The Trustee shall send notice in writing of such
Interest Rate Conversion to the Company one Business Day following the
notification of the Trustee by the trustee of the RPM, Inc. Tiers(SM) 
Certificates Trust RPM 1998-1 of such Interest Rate Conversion.

         (c) Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date, if the Debentures shall then bear interest at a Floating Rate,
the Holders of not less than 66_% in aggregate principal amount of the
Debentures will have the right to elect to convert the interest rate on all, but
not less than all, of the Debentures from such Floating Rate to the Fixed Rate

Holders' election to so convert the interest rate. Such notice to the Company
and the Trustee shall set forth the name of the Holders exercising such right
and a statement that a Swap Termination Date has occurred and that the Holders
wish to exercise their right to convert the interest rate to the Fixed Rate
pursuant to this Section. Any exercise of such conversion right shall be
irrevocable. Upon receipt of such notice by the Company, (i) any Floating Rate
Period then in effect shall terminate, (ii) a Fixed Rate Period will then be in
effect and be deemed to have been in effect at all times from the then most
recent Interest Payment Date on which interest has been paid or duly provided

Payment Date, from the Original Issuance Date) and (iii) no Floating Rate Period
shall thereafter be in effect at any time.

         (d) Certain Definitions. As used in this First Supplemental Indenture
with respect to the Debentures, the following terms have the following meanings:

         "Business Day" means any day, other than a Saturday or Sunday, or a day
on which banking institutions in New York, New York are authorized or obligated
by law or executive order to be closed.

         "Calculation Agent" means the Swap Counterparty, as calculation agent,
and its successors in such capacity under the Swap Agreement.

         "Final Maturity Date" means March 1, 2008.

         "Fixed Rate" means 6.50% per annum.

         "Fixed Rate Period" exists at any time until the Final Maturity Date at
which a Floating Rate Period is not in effect.

         "Floating Rate" means, (i) for any Interest Accrual Period during the
Initial Floating Rate Period, a rate per annum equal to the London interbank
offered rate for United States dollar deposits ("LIBOR") for a period of six
months minus .05% (the "Initial Floating Rate") and (ii) for any Interest
Accrual Period during the Subsequent Floating Rate Period, a rate per annum
equal to LIBOR for a period of three months (the "Subsequent Floating Rate").
Each such Floating Rate shall be determined from time to time on the Interest
Determination Date during such Interest Accrual Period by the Calculation Agent
in accordance with the following provisions (in each case, with all percentages
resulting from any calculation rounded to the nearest one hundred-thousandth of
a percent, with five one-millionths of a percent rounded upward; and all dollar
amounts used in or resulting from any such calculation will be rounded to the
nearest cent, with one-half cent rounded upward):

                  (i) For each applicable semiannual or quarterly period, LIBOR
will be determined on the basis of the offered rates for deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, commencing on
the first day of such period immediately following the related Interest
Determination Date, which appear on Telerate Page 3750 on the Dow Jones Telerate
Service (or such other page as may replace that page on that service for the
purpose of displaying London interbank offered rates of major banks) as of 11:00
a.m. (London time) on that Interest Determination Date. If such rate does not so
appear on Telerate Page 3750, LIBOR in respect of such Interest Determination
Date will be determined as described in (ii) below.

                  (ii) If on any applicable Interest Determination Date the rate
for deposits of U.S. dollars having a six-month or three-month maturity, as
applicable, does not appear on Telerate Page 3750 as specified in (i) above,
LIBOR will be determined on the basis of the rates at which deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, are offered
by major banks selected by the Calculation Agent in the London interbank market
at approximately 11:00 a.m. (London time) on the related Interest Determination
Date to prime banks in the London interbank market for a period commencing on
the first day of such period immediately following that Interest Determination
Date and in a principal amount of not less than $1 million that in the
Calculation Agent's judgment is representative for a single transaction in such
market at such time. The Calculation Agent will request the principal London
office of each such bank to provide a quotation of its rate. If at least two
such quotations are provided, LIBOR in respect of that Interest Determination
Date will be the arithmetic mean of such quotations. If fewer than two
quotations are provided, LIBOR in respect of that Interest 

<PAGE>   5



Determination Date will be the arithmetic mean of the rates quoted by major
banks in New York City selected by the Calculation Agent at approximately 11:00
a.m. (New York City time) on that Interest Determination Date for loans in U.S.

as applicable, commencing on the first day of such Interest Accrual Period
immediately following that Interest Determination Date and in a principal amount
of not less than $1 million that, in the Calculation Agent's judgment, is

final and binding in the absence of manifest error.

         "Floating Rate Period" means (i) the period from the Original Issuance
Date until the Interest Rate Reset Date (the "Initial Floating Rate Period") and
(ii) after the Initial Floating Rate Period, the period from the Interest Rate
Conversion Date until the Final Maturity Date (the "Subsequent Floating Rate
Period"). Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date (if any) and the election by Holders of not less than 66_% in
aggregate principal amount of the Debentures, (A) any Floating Rate Period then
in effect shall automatically terminate, (B) a Fixed Rate Period shall
automatically be in effect and be deemed to have been in effect at all times
from the then most recent Interest Payment Date on which interest has been paid
or duly provided for (or, if no such interest has been paid or duly provided for
on any Interest Payment Date from the Original Issuance Date) and (C) no
Floating Rate Period shall thereafter be in effect at any time.

         "Interest Accrual Period" means, for each Interest Payment Date, the
period from and including the prior Interest Payment Date (or, in the case of
the first Interest Accrual Period, from and including the Original Issuance
Date) to but excluding such Interest Payment Date.

         "Interest Determination Date" means (i) in the case of each Interest
Accrual Period occurring during the Initial Floating Rate Period, two Market
Days prior to the first or last day of such Interest Accrual Period (whichever
results in the higher rate) and (ii) in the case of each Interest Accrual Period
thereafter during a Floating Rate Period, the second Market Day next preceding
each LIBOR Reset Date within such Interest Accrual Period.

         "Interest Rate Reset Date" means March 1, 2000.

SIDE OF THIS SECURITY BEING COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE
TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE
RESALE RESTRICTION TERMINATION DATE.

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Debentures"), issued and to be issued in a single
series under an Indenture, dated as of June 1, 1995 as supplemented by the First
Supplemental Indenture dated as of March 5, 1998 (herein called the "Indenture",
which term shall have the meaning assigned to it in such instrument), between
the Company and The First National Bank of Chicago, as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
and reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Debentures and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. This Debenture is
one of the series designated on the face hereof, limited in aggregate principal
amount to $100,000,000.

         RPM, INC., a corporation duly organized and existing under the laws of
the State of Ohio (herein called the "Company", which term includes any
successor Person under the Indenture hereafter referred to), for value received,
hereby promises to pay to CEDE & CO., or registered assigns, the principal sum
of One Hundred Million and No/100 Dollars ($100,000,000) on March 1, 2008, and
to pay interest thereon from the Original Issuance Date or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on each March 1 and September 1 (each an "Interest
Payment Date"), determined as set forth herein, commencing September 1, 1998, at
the rate of interest determined as set forth herein, until the principal hereof
is paid or made available for payment. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Debenture (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be one Business Day prior to the
relevant Interest Payment Date (except that if the Debentures are no longer
represented by a global Security as a result of the occurrence of an event
specified in Section 305(a) of the Indenture, the Regular Record Date for such
interest payment shall be the close of business on the fifteenth day (whether or
not a Business Day), as the case may be, next preceding such Interest Payment
Date). In the event that any date on which interest is payable on the Debentures
is not a Business Day, then payment of the interest payable on such date will be
made on the next succeeding day which is a Business Day (without any interest or
other payment in respect of any such delay). Any such interest not so punctually
paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this
Debenture (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Debentures
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Debentures may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Debenture will be made at the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the 

<PAGE>   10


Company payment of interest may be made by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register.

         Except as provided above with respect to the payment of interest, any
payment on this Debenture due on any day which is not a Business Day in the City
of New York need not be made on such day, but may be made on the next succeeding
Business Day with the same force and effect as if made on the due date and no
interest shall accrue for the period from and after such date.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to herein by manual signature, this Debenture shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

         During any Floating Rate Period (as defined below), interest on this
Debenture shall be payable semi-annually in arrears on each Interest Payment
Date, commencing on September 1, 1998, at the applicable Floating Rate (as
defined below), determined and compounded on a quarterly basis or determined but
not compounded on a semiannual basis, as applicable. During any Fixed Rate
Period (as defined below), interest on this Debenture shall be payable
semi-annually in arrears on each Interest Payment Date at the Fixed Rate (as
defined below). Interest, whether accruing at a Floating Rate or the Fixed Rate,
will accrue from and including the Original Issuance Date or, if later, from and
including the most recent Interest Payment Date on which interest has been paid
or duly provided for. Interest on this Debenture calculated at a Floating Rate
for any period shall be computed on the basis of the actual number of days
elapsed in such period and a 360-day year. Interest on this Debenture calculated
at the Fixed Rate for any period shall be computed on the basis of a 360-day
year of twelve 30-day months and, for any period shorter than a full semi-annual
Interest Accrual Period for which interest is computed, on the basis of the
actual number of days elapsed in such period.

As used herein:

"Business Day" means any day, other than a Saturday or Sunday, or a day on which
banking institutions in New York, New York are authorized or obligated by law or
executive order to be closed.

"Calculation Agent" means the Swap Counterparty as calculation agent, and its
successors in such capacity under the Swap Agreement.

"Final Maturity Date" means March 1, 2008.

"Fixed Rate" means 6.50% per annum.

"Fixed Rate Period" exists at any time until the Final Maturity Date at which a
Floating Rate Period is not in effect.

"Floating Rate" means, (i) for any Interest Accrual Period during the Initial
Floating Rate Period, a rate per annum equal to the London interbank offered
rate for United States dollar deposits ("LIBOR") for a period of six months
minus .05% (the "Initial Floating Rate") and (ii) for any Interest Accrual
Period during the Subsequent Floating Rate Period, a rate per annum equal to
LIBOR for a period of three months (the "Subsequent Floating Rate"). Each such
Floating Rate shall be determined from time to time on the Interest
Determination Date during such Interest Accrual Period by the Calculation Agent
in accordance with the following provisions (in each case, with all percentages
resulting from any calculation rounded to the nearest one hundred-


<PAGE>   11


thousandth of a percent, with five one-millionths of a percent rounded upward;
and all dollar amounts used in or resulting from any such calculation will be
rounded to the nearest cent, with one-half cent rounded upward):

                  (i) For each applicable semiannual or quarterly period, LIBOR
will be determined on the basis of the offered rates for deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, commencing on
the first day of such period immediately following the related Interest
Determination Date, which appear on Telerate Page 3750 on the Dow Jones Telerate
Service (or such other page as may replace that page on that service for the
purpose of displaying London interbank offered rates of major banks) as of 11:00
a.m. (London time) on that Interest Determination Date. If such rate does not so
appear on Telerate Page 3750, LIBOR in respect of such Interest Determination
Date will be determined as described in (ii) below.

                  (ii) If on any applicable Interest Determination Date the rate
for deposits of U.S. dollars having a six-month or three-month maturity, as
applicable, does not appear on Telerate Page 3750 as specified in (i) above,
LIBOR will be determined on the basis of the rates at which deposits in U.S.
dollars having a six-month or three-month maturity, as applicable, are offered
by major banks selected by the Calculation Agent in the London interbank market
at approximately 11:00 a.m. (London time) on the related Interest Determination
Date to prime banks in the London interbank market for a period commencing on
the first day of such period immediately following that Interest Determination
Date and in a principal amount of not less than $1 million that in the
Calculation Agent's judgment is representative for a single transaction in such
market at such time. The Calculation Agent will request the principal London
office of each such bank to provide a quotation of its rate. If at least two
such quotations are provided, LIBOR in respect of that Interest Determination
Date will be the arithmetic mean of such quotations. If fewer than two
quotations are provided, LIBOR in respect of that Interest Determination Date
will be the arithmetic mean of the rates quoted by major banks in New York City
selected by the Calculation Agent at approximately 11:00 a.m. (New York City
time) on that Interest Determination Date for loans in U.S. dollars to leading
European banks, having a six-month or three-month maturity, as applicable,
commencing on the first day of such Interest Accrual Period immediately
following that Interest Determination Date and in a principal amount of not less
than $1 million that, in the Calculation Agent's judgment, is representative for
a single transaction in such market at such time.

         The Calculation Agent's determination of any interest rate will be
final and binding in the absence of manifest error.

"Floating Rate Period" means (i) the period from the Original Issuance Date
until the Interest Rate Reset Date (the "Initial Floating Rate Period") and (ii)
after the Initial Floating Rate Period, the period from the Interest Rate
Conversion Date until the Final Maturity Date (the "Subsequent Floating Rate
Period"). Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date (if any) and the election by Holders of not less than 66_% in
aggregate principal amount of the Debentures, (A) any Floating Rate Period then
in effect shall automatically terminate and a Fixed Rate Period shall
automatically be in effect, (B) a Fixed Rate Period shall automatically be in
effect and be deemed to have been in effect at all times from the then most
recent Interest Payment Date on which interest has been paid or duly provided
for (or, if no such interest has been paid or duly provided for on any Interest
Payment Date from the Original Issuance Date) and (C) no Floating Rate Period
shall thereafter be in effect at any time.

<PAGE>   12



"Interest Accrual Period" means, for each Interest Payment Date, the period from
and including the prior Interest Payment Date (or, in the case of the first
Interest Accrual Period, from and including the Original Issuance Date) to but
excluding such Interest Payment Date.

"Interest Determination Date" means (i) in the case of each Interest Accrual
Period occurring during the Initial Floating Rate Period, two Market Days prior
to the first or last day of such Interest Accrual Period (whichever results in
the higher rate) and (ii) in the case of each Interest Accrual Period thereafter
during a Floating Rate Period, the second Market Day next preceding each LIBOR
Reset Date within such Interest Accrual Period.

"Swap Rate" for any Reference Date means the bid side of the observable rates
published on Telerate page 19901 two Market Days prior to such Reference Date,
calculated on a semi-annual 30/360 basis, provided that, in the event such rate
is not available on such page, the Swap Rate shall be based on the bid side of
the observable rates published on Reuters page "TETC"/Telerate page 2103/4 on
such date, provided further that, in the event such rate is not available on
such page, the Swap Rate for such Reference Date shall be calculated by the
Calculation Agent based on the linear interpolation of the Swap Rate for which a
bid is observable for the Remaining Maturity next longer and the Remaining
Maturity next shorter than such Remaining Maturity.

"Swap Termination Date" means the Early Termination Date as defined in the Swap
Agreement.

         Effective on the Interest Rate Reset Date or on any anniversary thereof
to and including March 1, 2007 or if such date is not a Business Day, then on
the following Business Day (each, a "Reference Date"), if a Swap Termination
Date shall not have occurred by such date and the Swap Rate for an interest rate
swap with a remaining maturity (as set forth below, the "Remaining Maturity")
corresponding to the applicable Reference Date is greater than or equal to the
applicable reference rate (as set forth below, the "Reference Rate"), then the
interest rate on all, but not less than all, of the Debentures shall be

subsequent Interest Accrual Period (in accordance with the definition of
Floating Rate Period) (the "Interest Rate Conversion"). From and after the date

Day following the notification of the Trustee by the trustee of the RPM, Inc.
Tiers(SM) Certificates Trust RPM 1998-1 of such Interest Rate Conversion.

         Notwithstanding the foregoing, upon the occurrence of a Swap
Termination Date, if the Debentures shall then bear interest at a Floating Rate,
the Holders of not less than 66-2/3% in aggregate principal amount of the
Debentures will have the right to elect to convert the interest rate on all, but
not less than all, of the Debentures from such Floating Rate to the Fixed Rate
by delivering to the Company and the Trustee irrevocable written notice of such
Holders' election to so convert the interest rate. Such notice to the Company
and the Trustee shall set forth the name of the Holders exercising such right
and a statement that a Swap Termination Date has occurred and that the Holders
wish to exercise their right to convert the interest rate to the Fixed Rate
pursuant to this Section. Any exercise of such conversion right shall be
irrevocable. Upon receipt of such notice by the Company, (i) any Floating Rate
Period then in effect shall terminate, (ii) a Fixed Rate Period will then be in
effect and be deemed to have been in effect at all times from the then most
recent Interest Payment Date on which interest has been paid or duly provided
for (or, if no interest has been paid or duly provided for on any Interest
Payment Date, the Original Issuance Date) and (iii) no Floating Rate Period
shall thereafter be in effect at any time.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Debenture or certain restrictive covenants and
Events of Default with respect to this Debenture upon compliance with certain
conditions set forth in the Indenture.

         The Debentures are not subject to redemption at the option of the
Company or any Holder prior to maturity and will not be subject to any sinking

         If an Event of Default with respect to the Debentures shall occur and
be continuing, the principal of the Debentures may be declared due and payable
in the manner and with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Debentures at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of a majority in the principal amount of the
Debentures of each series at the time Outstanding, on behalf of the Holders of
all the Debentures of such series, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Debenture shall be conclusive and binding upon such Holder and upon all
future Holders of this Debenture and of any Debenture issued upon the
registration of transfer hereof or in 

<PAGE>   14


exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Debenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Debenture shall not have the right to institute any proceeding

Debentures, the Holders of not less than 25% in principal amount of the
Debentures at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonably satisfactory indemnity, and the Trustee shall
not have received from the Holders of a majority in principal amount of the
Debentures at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Debenture for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Debenture

Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Debentures
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         The Debentures are issuable only in registered form without coupons in
denominations of $100,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Debentures
are exchangeable for a like aggregate principal amount of Debentures and of like
tenor of a different authorized denomination, as requested by the Holder
surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither

                  Salary hereunder shall not be reduced without his written
                  consent.

                  amount equal to the product of Sullivan's annual Base Salary
                  in effect as of such date multiplied by five (5) or (ii) if
                  Sullivan shall so elect, the Company shall continue to pay him

         This Amendment No. 1 is made this 24th day of April, 1998 by the

                              W I T N E S S E T H:
                              --------------------

         WHEREAS, the Company has previously adopted the RPM, Inc. 1996 Key

         WHEREAS, the Company desires to amend the Plan to permit certain

         (1)      Section 1 of the Plan is hereby amended to add the following
                  paragraphs (m) and (n):

                  "(m)     The words "Immediate Family" shall mean a Qualified
                           Optionee's children, stepchildren, grandchildren,
                           parents, stepparents, grandparents, spouse, siblings

                           adoption.

                  (n)      The words "Qualified Optionee" shall mean an Optionee
                           who is either (i) the Chief Executive Officer or
                           individuals acting in a similar capacity during the
                           last completed fiscal year of the Company; or (ii)
                           one of the four (4) most highly compensated executive
                           officers, other than the Chief Executive Officer, at

                           Company."

         (2)      The second sentence of Section 5 of the Plan is hereby deleted
                  in its entirety and replaced with the following sentence:


<PAGE>   2



                  "Notwithstanding the preceding sentence, a Key Employee who
                  renounces in writing any right he or she may have to receive
                  stock options under the Plan shall not be eligible to receive
                  any stock options under the Plan; provided, however, that a
                  Qualified Optionee who transfers any or all of his or her
                  options pursuant to Section 7 (c) below shall continue to be
                  eligible to receive stock options hereunder."

         (3)      Paragraph (c) of Section 7 of the Plan is hereby deleted in
                  its entirety and replaced with a new paragraph (c) to read as
                  follows:

                  "(c)     Limitation on Exercise and Transfer of Option. Except
                           as otherwise provided in the event of an Optionee's
                           death, only the Optionee may exercise an option,
                           provided that (i) a guardian or other legal
                           representative who has been duly appointed for such
                           Optionee may exercise an option on behalf of the
                           Optionee and (ii) a transferee of an option that has
                           been transferred as permitted pursuant to
                           subparagraph (C) below may exercise such transferred
                           option subject to the terms and conditions of the
                           Plan. No option granted hereunder shall be
                           transferable other than (A) by the Last Will and
                           Testament of the Optionee or, if the Optionee dies
                           intestate, by the applicable laws of descent and
                           distribution, (B) to the extent approved by the
                           Committee, pursuant to a domestic relations order, or
                           (C) to the extent approved by the Committee with
                           respect to any option that is not an Incentive Stock
                           Option, by a Qualified Optionee who transfers such
                           option to a member of his or her Immediate Family or
                           to a trust or partnership established for the
                           exclusive benefit of the members of his or her
                           Immediate Family.

                           Notwithstanding subparagraph (C) above to the
                           contrary, no transfer shall be made pursuant to said
                           subparagraph (C):

                           (I)      to the extent the transfer is made for
                                    consideration; or

                           (II)     to the extent that such transferability
                                    would cause Form S-8 not to be available to
                                    register the Common Stock that is issuable
                                    upon exercise of the options so transferred.

                           Any purported assignment, transfer, pledge,
                           hypothecation or other disposition of any of the
                           options attempted contrary to the provisions of this
                           Plan, or any levy of execution, attachment or other
                           process attempted upon any of the options, shall be
                           null and void and without effect. Any person to whom
                           an option is transferred by the Optionee as permitted
                           by subparagraph (C) above shall thereafter succeed to
                           all of the rights of the Optionee with respect to
                           exercising the option, provided that the transferee
                           shall have the right to exercise such option only if
                           and to the extent the 



                                      -2-
<PAGE>   3


                           Optionee would have had the right to exercise such 
                           option had the transfer not been made."

         (4)      The initial provision of Section 10 is hereby deleted in its
                  entirety and replaced with the following provision:

                  "The Committee may condition its grant of any option hereunder
                  upon receipt of an investment representation from the
                  Optionee, or any other person or entity which is entitled to
                  exercise an option hereunder, which shall be substantially
                  similar to the following:"

         IN WITNESS WHEREOF, the Committee has caused this Amendment No. 1 to be
executed as of the date set forth above.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
AND FINANCIAL CONDITION
RPM, INC. AND SUBSIDIARIES
- --------------------------------------------------------------------------------

Results of Operations


Fiscal 1998 Compared To Fiscal 1997

       The Company achieved its 51st consecutive record year of sales and
earnings in the 1998 fiscal year. Sales reached $1.62 billion, a 20% increase
over 1997, while earnings grew 12%, to $87.8 million.

       On March 31, 1998, the Company acquired The Flecto Company, Inc.
("Flecto"), a leading manufacturer of wood finishes and equipment for the retail
do-it-yourself wood and floor finishing markets [refer to Note A (2)]. With
annual sales of approximately $50 million, Flecto has the leading market share
position in Canada and substantial market share in the United States and will
complement the Company's other leading consumer name brand companies targeting
the retail do-it-yourself market, such as Rust-Oleum, Zinsser, Bondex and Bondo.

       The Flecto acquisition and that of Tremco, Inc. on February 1, 1997,
along with several smaller acquisitions and joint ventures, net of several small
divestitures, accounted for approximately 65% of the 1998 sales increase. The
Company's existing operations generated the balance of the sales increase,
growing at the rate of 7% for the year, almost entirely from higher unit volume
as pricing adjustments have been negligible. The consumer businesses grew
slightly faster than the industrial in 1998. Exchange rate differences had a
slight negative effect of less than 1% of sales versus last year and, should the
dollar continue to strengthen, this trend will continue.

       The UPS strike affected shipments and caused some loss of business early
in the year, and generally slower retail markets affected consumer operations
during the first half of the year. Substantially all operating units experienced
generally stronger growth in the second half.

       The Company's gross profit margin has continued to strengthen, improving
to 44.8% from 44.3% a year ago. This is the result of the stronger average
margins of the recently acquired companies, Tremco and Flecto, coupled with
margin improvements at Tremco throughout the year, mainly from purchasing
savings by being part of a larger group, and the successful restructuring of its
operations which is on schedule. Raw material price changes were not a
significant issue this year and the Company is confident that such changes in
the foreseeable future will continue to be effectively managed.

       Selling, general and administrative expenses increased to 33.3% of sales
from 31.8% in 1997. Tremco and Flecto, with their proportionately higher costs
in this category, plus acquisition related expenses, account for the majority of
this increase. Existing operations increased certain promotional and related
spending to further the Company's growth, as planned. The consumer businesses,
in particular, also incurred higher freight costs in 1998 to meet the increasing
demands for smaller, more frequent shipments to their customers, while the Far
East economic situation precipitated certain bad debts and exchange losses among
the industrial businesses.

       Interest expense increased $6.2 million in 1998 [refer to Note A(11)],
reflecting the additional indebtedness to acquire Tremco, Flecto, and other
smaller acquisitions, plus non-cash interest accretion. Debt reductions and
fractionally lower interest rates between years reduced net interest expense,
comparatively.

       The tax rate improved in 1998 [refer to Note C], with the most
significant improvements coming from the foreign sales corporation (FSC)
resulting in more favorable tax treatment of the Company's exports from the
U.S., proportionately lower state and local taxes, and fewer tax disadvantaged
losses among foreign countries.

       Approximately half the growth in earnings and earnings per share was
generated by existing operations, and the balance from the net effect of
acquisitions and divestitures.

       The decline in the Company's net income margin to 5.4% from 5.8% a year
ago is the result of the Tremco acquisition and its comparatively lower return
on sales, primarily as a result of related acquisition costs. Tremco's return
improved significantly this year and should continue to improve with growth
combined with the savings that have been generated through continuing
restructuring programs.

       The Company's earnings per share this year were affected by the averaging
of Company shares issued in connection with Flecto and a smaller acquisition,
causing a 12% increase in earnings to relate to an 11% increase in diluted
earnings per share. All previously reported per share data have been restated to
reflect a 25% stock dividend issued December 8, 1997.

       Subsequent to year-end, on July 8, 1998, the Company called for the
redemption of all of its $400 million face value at maturity Liquid Yield Option
Notes (LYONs) due 2012 [refer to Note B]. The accreted value of the LYONs
securities on the August 10, 1998 redemption date was approximately $192
million. Bondholders converted approximately $160 million of this amount into
10.1 million Company shares, which will correspondingly increase the Company's
basic shares outstanding. The remaining 2.1 million shares that had been
reserved for this conversion will now be removed from the calculation of diluted
earnings per share. The first-year interest savings resulting from the LYONs
converted into Company shares will amount to approximately $8 million on an
annualized basis.

       Environmental obligations continue to be appropriately addressed and,
based upon the latest available information, it is not anticipated that the
outcome of such matters will materially affect the Company's results of
operations or financial position. However, such costs could be material to
results of operations in a future period [refer to Note H].

       The Company's foreign sales and results of operations are subject to the
impact of foreign currency fluctuations. As most of the Company's foreign
operations are in countries with fairly stable currencies, such as Belgium and
Canada, this effect has not been significant. In addition, foreign debt is
denominated in the 



                                       22
<PAGE>   2
respective foreign currency, thereby eliminating any related translation impact
on earnings. Should the dollar continue to strengthen, the Company's foreign
results of operations will be negatively impacted; to date, the effect has not
been significant. The Company does not currently hedge against the risk of
exchange rate fluctuations [refer to Note I].

       The Company has evaluated its existing information systems to identify
the changes needed for Year 2000 compliance. Because the Company is highly
decentralized, comprised of multiple operating companies, the need to upgrade or
replace a large system does not exist, thereby minimizing the complexity of the
required modifications. The Year 2000 evaluation effort has included the use of
outside consultants to independently test the effectiveness of planned
modifications. Although conclusive cost estimates have not been determined, it
is anticipated that Year 2000 costs will result in increased expenses and
capital expenditures during fiscal years 1999 and 2000. The Company does not
anticipate, however, that Year 2000 compliance costs will have a material effect
on its financial position or results of operations in those fiscal years.

Results of Operations

FISCAL 1997 COMPARED TO FISCAL 1996

       Fibergrate Composite Structures Incorporated (Fibergrate), formerly known
as Okura Holdings, Inc., was acquired on June 13, 1996. With annual sales of
approximately $40 million, Fibergrate is a leading global manufacturer of molded
and pultruded fiberglass reinforced plastic grating products used for pedestrian
walkways, platforms, staircases and similar types of industrial structures.
Fibergrate offers the Company an attractive opportunity to capitalize on market,
product and customer synergies with its sister companies, particularly Stonhard
in flooring systems.

       On February 1, 1997, the Company completed the acquisition of Tremco,
Inc., Cleveland, Ohio. Tremco manufactures roofing systems, sealants and
coatings under the Tremco brand name selling primarily to the building
maintenance market. Tremco's product lines and distribution network complement
many of the Company's operations. Upon its acquisition, Tremco began major
restructuring and, in June 1997, the Company completed the sale of Tremco's $70
million insulating glass unit (Swiggle) and $10 million Autoglass division, both
of which served OEM markets unrelated to RPM's core business. In accordance with
accounting standards, the Company's results of operations did not include the
results of Swiggle or Autoglass or the associated interest expense related to
the respective borrowings being repaid with the sale proceeds [refer to Note A
(2)]. As a result of these transactions, Tremco had a restructured annual
revenue base of approximately $230 million.

       The Fibergrate and Tremco acquisitions and that of Dryvit Systems, Inc.
(Dryvit) on September 21, 1995, along with several smaller acquisitions and
joint ventures, net of several small divestitures, accounted for approximately
60% of the 1997 sales increase. The Company's existing operations generated the
balance of the sales increase, approximately 8%, net of divestitures, slightly
favoring the industrial lines, and almost entirely from higher unit volume as
pricing adjustments were negligible year-to-year. Exchange rate differences had
a slight negative effect on sales in 1997 versus 1996.

       The Company's gross profit margin strengthened to 44.3% in 1997 from
42.8% in 1996. Nearly half of the 1997 improvement came from the efforts of
existing operations, where leveraged purchasing of significant materials
resulted in a number of lower raw material costs, primarily among consumer
lines, and where conversion costs continue to be appropriately controlled. The
balance of the gross profit margin improvement was the result of stronger
average margins among the acquired companies, particularly Fibergrate and
Tremco, coupled with weaker margins among the companies recently divested.

       Selling, general and administrative expenses increased in 1997 to 31.8%
of sales compared with 30.0% in 1996. A $2 million insurance recovery plus
several other non-recurring expense reductions during 1996, coupled with planned
increases in promotional spending to further the Company's growth, and the
timing of certain expenses in 1997, caused the majority of the percentage change
in this expense category. The recent acquisitions, especially Tremco, and
divestitures accounted for the remainder of this percentage difference.

       During 1997, certain businesses and assets were divested in pursuit of
management's commitment to its core markets and the reduction of debt created by
the Tremco acquisition. The net gains that resulted from these divestitures were
not material to the Company's results.

       Interest expense increased $6.8 million in 1997, driven primarily by
additional indebtedness associated with Tremco, Fibergrate, Dryvit and other
acquisitions. The reduction of debt from year-to-year, and fractionally lower
interest rates between years, reduced net interest expense comparatively.

       The tax rate improved in 1997, primarily through the establishment of a
foreign sales corporation. This benefit was somewhat reduced, however, by tax
disadvantaged losses of Tremco in several foreign countries.

       The 1997 decline in the Company's net income margin to 5.8% from 6.1% in
1996 was the result of the Tremco acquisition, which added approximately $74
million to fiscal 1997 sales and, as expected, did not contribute to earnings
due to the seasonality of their product lines and related acquisition costs. The
Company's 1997 net income margin would have been 6.1% were it not for this
effect.

       The Company's earnings per share in 1997 were affected by the averaging
of Company shares issued in connection with the September 1995 Dryvit
acquisition, causing the 14% increase in earnings to compare with a 10% increase
in diluted earnings per share.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
AND FINANCIAL CONDITION
RPM, INC. AND SUBSIDIARIES
- --------------------------------------------------------------------------------


Capital Resources and Liquidity

CASH PROVIDED FROM OPERATIONS

       The Company generated cash from operations of $111 million in 1998, $42
million more than during 1997, on an earnings increase of $9.5 million. This is
primarily attributable to the seasonality of Tremco's business between its date
of acquisition, February 1, 1997, and May 31, 1997. There were also temporary
accumulations of certain inventories a year ago to take advantage of pricing
opportunities and to accommodate several new product introductions.

       Cash flow from operations continues to be the primary source of financing
the Company's internal growth, with limited use of short-term credit.

INVESTING ACTIVITIES

       The Company is not capital intensive, but continually invests in capital
expenditures primarily to accommodate the Company's continued growth through
improved production and distribution efficiency and capacity, and enhanced
administration. Such expenditures generally do not exceed depreciation and
amortization in a given year. Capital expenditures in 1998 amounted to $60
million compared with depreciation and amortization of $57 million.

       The investment of $48 million in new businesses this year reflects the
acquisition of Flecto and several other smaller businesses and assets this year,
net of cash acquired. The Company historically has acquired complementary
businesses and this trend is expected to continue.

       The Company's captive insurance company invests in and trades marketable
securities in the ordinary course of conducting its operations, and this
activity will continue. The differences between years are primarily attributable
to the timing of investments.

       Earlier this year the Company collected a $23.3 million May 31, 1997
receivable associated with the sale of a business and completed the sales of
Tremco's insulating glass unit and Autoglass division for a net amount of $107.5
million, as previously discussed under Results of Operations.

FINANCING ACTIVITIES

       The $130.8 million net proceeds mentioned above were used to reduce the
Company's revolving credit facility, $51 million of additional debt was incurred
to finance acquisitions during the year and $9.6 million of non-cash accretion
was added to long-term debt. The difference is mainly related to currency
translation changes.

       As a result of these transactions, the Company has a debt-to-capital
ratio of 56% compared to 62% at May 31, 1997, while interest coverage is five
times on a reported basis and nearly seven times on a cash basis. The LYONs
redemption subsequent to year-end, referred to above, has resulted in a decrease
in long-term debt of approximately $160 million and an equivalent increase in
shareholders' equity. The Company's revolving credit facility was used to fund
the LYONs securities redeemed for cash in the amount of approximately $32
million. The Company's debt-to-capital ratio has been reduced to 44% and
interest coverage has improved to six times as a result of this redemption.

       On March 5, 1998, the Company completed a public offering of $100 million
of Notes due 2008 (the "Notes"). The Notes are unsecured obligations of the
Company and rank pari passu with all other unsecured obligations of the Company.
During the first two years, the Notes will bear interest, payable semi-annually
in arrears, at a rate per annum equal to the London Interbank Offered Rate
("LIBOR") for U.S. dollar deposits for a period of six months, minus 5 basis
points. During any subsequent period, the Notes will bear interest, payable
semi-annually in arrears, at a rate of 6.50% per annum, or the three month LIBOR
rate.

       The total net proceeds of this offering of approximately $99 million were
used to reduce the outstanding balance of the Company's $500 million revolving
line of credit. The Company subsequently reduced the limit of this credit
facility to $300 million.

       The Company acquired Flecto for a combination of cash and the issuance of
Company shares, with the Company's revolving credit facility being utilized for
the cash portion of this transaction.

       The stronger dollar effect on the Company's foreign net assets has tended
to reduce shareholders' equity and this trend could continue if the dollar
continues to strengthen, and the growth of these net assets continues.

       The Company maintains excellent relations with its banks and other
financial institutions to further enable the financing of future growth
opportunities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- MAY 31, 1998, 1997 AND 1996
RPM, INC. AND SUBSIDIARIES
- --------------------------------------------------------------------------------

Note A -- Summary of Significant Accounting Policies

1. PRINCIPLES OF CONSOLIDATION

       The consolidated financial statements include the accounts of RPM, Inc.
and its majority owned domestic and foreign subsidiaries. The Company accounts
for its investment in less than majority owned joint ventures under the equity
method. Intercompany accounts, transactions and unrealized profits and losses
are eliminated in consolidation.

       Certain reclassifications have been made to prior year amounts to conform
with the current year presentation.

2. BUSINESS COMBINATIONS

    During the two year period ended May 31, 1998, the Company completed several
acquisitions. As reported last year, the Company acquired all the outstanding
shares of Tremco, Incorporated and Fibergrate Composite Structures, Inc. On
March 31, 1998, the Company acquired all the outstanding shares of The Flecto
Company, Inc. and affiliates.

       These acquisitions as well as several small product line acquisitions
have been accounted for by the purchase method of accounting and the difference
of approximately $187,000,000 between the fair value of net assets acquired and
the purchase consideration of $427,000,000 ($381,000,000 in cash and 2,777,000
of the Company's shares) has been allocated to goodwill. The purchase price
allocations have been based on preliminary estimates, which may be revised at a
later date. The assets, liabilities and operating results of these companies are
reflected in the Company's financial statements from their respective dates of
acquisition forward.

       As reported last year, the Company completed the sale of Tremco's Windows
and Autoglass businesses for $107,000,000. In addition, the Company also
completed several other divestitures and product line restructurings during the
past two years resulting in an immaterial gain with additional proceeds
to the Company of approximately $36,000,000.

       The following data summarizes, on an unaudited pro forma basis, the
combined results of operations of the Company and the significant businesses
acquired for the two years ended May 31, 1998. The pro forma amounts give effect
to appropriate adjustments resulting from the combination, but are not
necessarily indicative of future results of operations or of what results would
have been for the combined companies.

3. FOREIGN CURRENCY

       The functional currency of foreign subsidiaries is their local currency.
Accordingly, for the periods presented, assets and liabilities have been
translated using exchange rates prevailing at year-end while income and expense
for the periods have been translated using an average exchange rate. The
resulting translation adjustments have been recorded in shareholders' equity and
will be included in net earnings only upon the sale or liquidation of the
underlying foreign investment, which is not contemplated at this time.
Transaction gains and losses have been immaterial during the past three fiscal
years.

4. CASH AND SHORT-TERM INVESTMENTS

       For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents. The Company does not believe it is exposed to any
significant credit risk on cash and short-term investments.

5. MARKETABLE SECURITIES

       Marketable securities of $21,319,000 and $11,338,000 at May 31, 1998 and
1997, respectively, are included in other current assets and are stated at cost
which approximates their fair market value.

6. FINANCIAL INSTRUMENTS

       The Company's financial instruments recorded on the balance sheet include
cash and short-term investments, accounts receivable, accounts payable and debt.
The carrying amount of cash and short-term investments, accounts receivable and
accounts payable approximates fair value because of their short term maturity.

       The carrying amount of the Company's debt instruments approximates fair
value based on quoted market prices, variable interest rates, or borrowing rates
for similar types of debt arrangements.

7. INVENTORIES

       Inventories are stated at the lower of cost or market, cost being
determined substantially on a first-in, first-out (FIFO) basis and market being
determined on the basis of replacement cost or net realizable value. Inventory
costs include raw material, labor and manufacturing overhead. Inventories were
composed of the following major classes:

8. DEPRECIATION

       Depreciation is computed over the estimated useful lives of the assets
primarily using the straight-line method. The annual depreciation rates are
based on the following ranges of useful lives:
- --------------------------------------------------------------------
<TABLE>

<S>                                                   <C>
Land improvements                                     5 to 35 years 
Buildings and improvements                            5 to 50 years
Machinery and equipment                               3 to 20 years
</TABLE>


9. INTANGIBLES

       The excess of cost over the underlying value of the net assets of
companies acquired is being amortized on the straight-line basis, primarily over
forty years. Amortization expense charged to operations for the three years
ended May 31, 1998 was $12,435,000, $9,916,000 and $7,562,000, respectively.
Cost of businesses over net assets acquired is shown net of accumulated
amortization of $56,611,000 at May 31, 1998 ($44,351,000 at May 31, 1997).

       Intangible assets also represent costs allocated to formulae, trademarks,
trade names and other specifically identifiable assets arising from business
acquisitions. These assets are being amortized using the straight-line method
over periods of 5 to 40 years. The Company assesses the recoverability of the
excess of cost over the assigned value of net assets acquired by determining
whether the amortization of the balance over its remaining life can be recovered
through undiscounted future operating cash flows of the acquired operations.
Amortization expense charged to operations for the three years ended May 31,
1998, was $11,473,000, $10,936,000 and $7,553,000 respectively.

       Other intangible assets consist of the following major classes:

10. RESEARCH AND DEVELOPMENT

       Research and development costs are charged to operations when incurred
and are included in operating expenses. The amounts charged for the three years
ended May 31, 1998, were $15,815,000, $14,610,000 and $13,712,000, respectively.
The customer sponsored portion of such expenditures was not significant.

11. INTEREST EXPENSE, NET

       Interest expense is shown net of investment income which consists of
interest, dividends and capital gains. Investment income for the three years
ended May 31, 1998, was $4,154,000, $2,059,000 and $2,005,000, respectively.

12. INCOME TAXES

       The Company and its wholly owned domestic subsidiaries file a
consolidated federal income tax return. The tax effects of transactions are
recognized in the year in which they enter into the determination of net income,
regardless of when they are recognized for tax purposes. As a result, income tax
expense differs from actual taxes payable. The accumulation of these differences
at May 31, 1998, is shown as a noncurrent liability of $58,059,000 (net of a
noncurrent asset of $40,984,000). At May 31, 1997, the noncurrent liability was
$70,210,000 (net of a noncurrent asset of $31,773,000). The Company does not
intend to distribute the accumulated earnings of consolidated foreign
subsidiaries amounting to $69,691,000 at May 31, 1998, and $48,453,000 at May
31, 1997, and therefore no provision has been made for the taxes which would
result if such earnings were remitted to the Company.

13. ESTIMATES

       The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- MAY 31, 1998, 1997 AND 1996 
(CONT.)
RPM, INC. AND SUBSIDIARIES


 Note D -- Common Shares

       There are 200,000,000 common shares authorized with a stated value of
$.015 per share. At May 31, 1998 and 1997, there were 100,254,000 and 98,029,000
shares outstanding respectively, each of which is entitled to one vote.

       Share data for May 31, 1997 and May 31, 1996, have been restated to
reflect a 25% stock dividend in December 1997.

       Basic earnings per share are based on the weighted average number of
common shares outstanding during each year (98,527,000 in 1998, 97,285,000 in
1997 and 95,208,000 in 1996). In computing diluted earnings per share, the
number of common shares was increased by common stock options with exercisable
prices lower than the average market prices of common shares during each year
and reduced by the number of shares assumed to have been purchased with proceeds
from the exercised options.

       The Company has options outstanding under three stock option plans, the
1979 Nonqualified Stock Option Plan, the 1989 Stock Option Plan and the 1996 Key
Employees Stock Option Plan which provide for the granting of options for up to
4,500,000 shares. These options are generally exercisable cumulatively in equal
annual installments commencing one year from the grant date and have expiration
dates ranging from September 1998 to May 2008. At May 31, 1998, 2,856,000 shares
(4,500,000 May 31, 1997) were available for future grant.

       Transactions during the last two years are summarized as follows:

       The Company is accounting for its stock option plans under the provisions
of APB Opinion No. 25 and, accordingly, no compensation cost has been
recognized. If compensation cost had been determined based on the fair value at
the grant date for awards under this plan consistent with the method prescribed
by SFAS No. 123, the Company's net income and earnings per share for the years
ended May 31, 1998 and 1997, would have been reduced to the pro forma amounts
indicated in the following table:

       The fair value of each option is estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted-average

and 27.5% for 1997; the expected life is 7.0 and 6.9 years, with dividend yields
of 2.9% and 2.8% and risk-free interest rates of 6.2%
and 6.3%, for 1998 and 1997, respectively.

Note E -- Leases


       At May 31, 1998, certain property, plant and equipment were leased by the
Company under long-term leases. Certain of these leases provide for increased
rental based upon an increase in the cost-of-living index. Future minimum lease
commitments as of May 31, 1998, for all noncancellable leases are as follows:

$8,804,000 in 1997 and $6,614,000 in 1996. Capitalized leases were insignificant
for the three years ended May 31, 1998.

 Note F -- Retirement Plans



       To provide uniform retirement income for its non-union employees, the
Company has a defined benefit retirement plan in which substantially all
non-union employees participate. The Retirement Plan is a non-contributory plan
fully paid for by the Company, with accrued benefits vesting after five years of
service. This plan provides benefits that are based on years of service and
average compensation. Benefits for union employees are provided by separate
plans and are generally based on years of service. The Company's funding policy
is to contribute annually an amount




                                       32
<PAGE>   12



that can be deducted for federal income tax purposes using a different actuarial
cost method and different assumptions from those used for financial reporting.

       The net periodic pension cost for the three years ended May 31, 1998,
included the following components:

       The general discount rate and rate of increase in future compensation
levels used in determining the actuarial present value of the projected benefit
obligations were 7% (8% for May 31, 1997) and 4.5% (5% for May 31, 1997),
respectively. The expected long-term rate of return on assets was 8.5%. The
plans' assets consist primarily of stocks, bonds and fixed income securities.

       In addition, the Company recognized $1,065,000 in pension income during
the year ended May 31, 1998, due to various one-time curtailment and/or
settlement events.

       Pursuant to the provisions of SFAS No. 87, "Employers' Accounting for
Pensions," intangible assets of $143,000 and $148,000 were recorded as of May
31, 1998 and 1997, respectively, in order to recognize the required minimum
liability.

their collective bargaining groups. Contributions to these plans were immaterial
for the three-year period ended May 31, 1998. In addition to the defined benefit
plans described above, the Company sponsors an employee savings plan under
Section 401(k) of the Internal Revenue Code. The Plan covers substantially all
non-union employees in the United States. The Plan provides for matching
contributions in Company shares based upon qualified employee contributions.
Matching contributions charged to income were $4,001,000 and $2,229,000 for
years ended May 31, 1998 and 1997, respectively.

Note G -- Post-Retirement Health Care Benefits


       In addition to the defined benefit pension plan, the Company also
provides health care benefits to certain of its retired employees through
unfunded plans. Employees become eligible for these benefits if they meet
minimum age and service requirements. The components of this expense for the
three years ended May 31, 1998 were as follows:

       In addition, the Company recognized $181,000 in income due to the
curtailment of these benefits at a union location.

       The accumulated post-retirement obligation recognized on the May 31,
1998 and May 31, 1997 balance sheets are comprised of the following components:

</TABLE>

       The general discount rate used in determining the accumulated
post-retirement benefit obligation as of May 31, 1998 was 7% (8% at May 31,
1997). A 10% increase in the cost of covered health care benefits was generally
assumed for fiscal 1998 (12% for fiscal 1997). This trend rate in all cases is
assumed to decrease to 5% after several years and remain at that level
thereafter except for various union plans which will cap at alternate benefit
levels. A 1% increase in the health care costs trend rate would have increased
the accumulated post-retirement benefit obligation as of May 31, 1998 by
$1,296,000 and the net post-retirement expense by $115,000.

       The Company, through its wholly owned insurance subsidiary, provides
certain insurance coverage, primarily product liability, to the Company's other
domestic subsidiaries. Excess coverage is provided by outside carriers. The
Company has provided the reserves reflected above to provide for these losses as
well as other uninsured claims. Provision for estimated warranty costs is
recorded at the time of sale and periodically adjusted to reflect actual
experience.

       In addition, the Company, like others in similar businesses, is involved
in several proceedings relating to environmental matters. It is the Company's
policy to accrue remediation costs when it is probable that such efforts will be
required and the related costs can be reasonably estimated. These liabilities
are undiscounted and do not take into consideration any possible recoveries of
future insurance proceeds or claims against third parties. Due to the
uncertainty inherent in the estimation process, it is at least reasonably
possible that actual costs will differ from estimates, but, based upon
information presently available, such future costs are not expected to have a
material adverse effect on the Company's competitive or financial position or
its ongoing results of operations. However, such costs could be material to
results of operations in a future period.

Note I -- Industry Segment and Geographic Area Information

       The Company operates principally in one business
segment-the manufacture and sale of protective coatings. In computing net income
for foreign subsidiaries, no allocations of general corporate expenses have been
made.

       Information concerning the Company's operations in different geographical
areas of the Company's business at May 31, 1998, 1997 and 1996 and for the years
then ended is summarized as follows:

number of shares outstanding in each quarter.

Note K -- Recently Issued Accounting Standards


       The FASB recently issued SFAS No. 130, Reporting Comprehensive Income,
SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information and SFAS No. 132, Employers' Disclosure about Pensions and Other
Post-retirement Benefits. SFAS No. 130 provides for the reporting and
presentation of comprehensive income and its components. SFAS No. 131
establishes standards for defining operating segments and reporting certain
information about such segments. SFAS No. 132 revised disclosure requirements
relative to pension and other post-retirement benefits. Since these statements
only impact how financial information is disclosed in interim and annual
periods, the adoption of these standards in 1999 will not impact the Company's
financial condition or results of operations.

Independent Auditors Report

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS
RPM, INC. AND SUBSIDIARIES
MEDINA, OHIO

       We have audited the accompanying consolidated balance sheets of RPM, Inc.
and Subsidiaries as of May 31, 1998 and 1997, and the related consolidated
statements of income, shareholders' equity and cash flows for each of the years
in the three-year period ended May 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

       We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion. In our
opinion, the consolidated financial statements referred to above present fairly,
in all material respects, the financial position of RPM, Inc. and Subsidiaries
at May 31, 1998 and 1997, and the results of their operations and their cash
flows for each of the years in the three-year period ended May 31, 1998, in
conformity with generally accepted accounting principles.
