                                   RPM, INC.

                      1979 NON-QUALIFIED STOCK OPTION PLAN

               1.      PURPOSE OF THE PLAN

                The Plan is intended to provide a niethod of providing key
employees of RPM, Inc. (the 'Company") and its subsidiaries with greater
incentive to serve and promote the interests of the Company and its
shareholders. The premise of the Plan is that, if such key employees acquire a
proprietary interest in the business of the Company or increase such proprietary
interest as they may already hold, then the incentive of such key employees to
work toward the Company's continued success will be commensurately increased.
Accordingly, the Company will, from time to time during the effective period
of the Plan, grant to such employees as may be selected to participate in the
Plan options to purchase Common Shares, without par value ("Shares"), of the
Company on the terms and subject to the conditions set forth in the Plan.

               2.      ADMINISTRATION OF THE PLAN

                The Plan shall be administered by the Compensation Committee of
the Board of Directors or by such other Committee composed of no fewer than
three (3) members of the Board of Directors of the Company as may be designated
by the Board of Directors (the "Committee"), provided that the Committee shall
not include any person who has been eligible to receive options under the Plan
or under any other plan of the Company entitling the participants therein to
acquire Shares, options to purchase Shares, or stock appreciation rights of the
Company at any time within the 12-month period immediately preceding the date on
which such person becomes a member of the Committee. A majority of the Committee
shall constitute a quorum, and the acts of a majority of the members present at
any meeting at which a quorum is present, or acts approved in writing by all of
the members, shall be the acts of the Committee.

                Subject to the provisions of the Plan, the Committee shall have
full and final authority, in its absolute discretion, (a) to determine the
employees to be granted options under the Plan, (b) to determine the number of
Shares subject to each option, (c) to determine the time or times at which
options will be granted, (d) to determine the option price of the Shares subject
to each option, which price shall not be less than the minimum specified in
Section 6 of the Plan, (e) to determine the time or times when each option
becomes exercisable and the duration of the exercise period, (f) to determine
the terms and conditions under which the Committee shall accept the surrender of
an option or any portion thereof pursuant to Section 9 of the Plan and to
determine the form in which payment for such surrendered option or portion
thereof shall be made, (g) to prescribe the form or forms of the instruments
evidencing any options granted under the Plan (which forms shall be consistent
with the Plan), (h) to adopt, amend and rescind such rules and regulations as,
in the Committee's opinion, may be advisable in the administration of the Plan,
and (i) to construe and interpret


                                      A-1


   2



the Plan, the rules and regulations and the instruments evidencing options
granted under the Plan and to make all other determinations deemed necessary or
advisable for the administration of the Plan. Any decision made or action taken
by the Committee in connection with the administration, interpretation, and
implementation of the Plan and of its rules and regulations, shall, to the
extent permitted by law, be conclusive and binding upon all optionees under the
Plan and upon any person claiming under or through such an optionee.

                3.      SHARES AVAILABLE FOR OPTIONS

                Subject to the provisions of Section 10 of the Plan, the
aggregate number of Shares for which options may be granted under the Plan shall
not exceed four hundred thousand (400,000).

                The Shares to be delivered upon exercise of options under the
Plan shall be made available, at the discretion of the Board of Directors,
either from the authorized but unissued Shares of the Company or from Shares
held by the Company as treasury shares, including Shares purchased in the open
market.

                If an option granted under the Plan shall expire or terminate
unexercised as to any Shares covered thereby, such Shares shall thereafter be
available for the granting of other options under the Plan. If, however, an
option granted under the Plan shall be accepted for surrender pursuant to terms
and conditions determined by the Committee under Section 9, any Shares covered
thereby shall not thereafter be available for the granting of other options
under the Plan.

                4.      ELIGIBILITY

                Options will be granted only to persons who are employees of the
Company or of a subsidiary of the Company. The term "subsidiary" as used herein
shall mean any corporation, a majority of the stock of which having normal
voting rights is owned directly or indirectly by the Company. The term
"employees" shall include officers as well as all other employees of the Company
and its subsidiaries and shall include Directors who are also employees of the
Company or of a subsidiary of the Company. Neither the members of the Committee
nor any other member of the Board of Directors who is not an employee of the
Company (or of a subsidiary of the Company) shall be eligible to receive an
option under the Plan.

                In selecting the persons to whom options shall be granted under
the Plan, as well as in determining the number of Shares subject to and the type
and terms and provisions of each option, the Committee shall weigh such factors
as it shall deem relevant to accomplish the purpose of the Plan, namely, to
enhance the incentive of those key employees of the Company and its subsidiaries
who exert authority over and are responsible for the management and conduct of
the Company's business. A person who has been granted an option under the Plan
may be granted an additional option or options if the Committee shall so
determine.

               5.      TERM OF OPTIONS

                The full term of each option granted under the Plan shall be
such period as the Committee shall determine, but shall not be more than ten
years from the date of granting thereof.

                                      A-2

   3




Each option shall be subject to earlier termination as provided in Paragraphs
(c) and (d) of Section 8 and in Section 9 of the Plan.

                The Committee may, with the concurrence of the affected
optionee, cancel any option granted under the Plan and authorize the grant of a
new option or options to buy Shares in such number and at such price as the
Committee shall determine, subject to the provisions of the Plan.

                6.      OPTION PRICE

                The option price shall be determined by the Committee at the
time any option is granted but shall not be less than 100 per cent of the fair
market value of the Shares covered thereby at the time the option is granted,
such fair market value to be determined in accordance with procedures to be
established by the Committee.

                7.      NON-TRANSFERABILITY OF OPTION

                No option granted under the Plan shall be transferable by the
optionee otherwise than by will or the laws of descent and distribution, and
such option may be exercised during the optionee's lifetime only by the optionee
or by his guardian or legal representative.

                8.      EXERCISE OF OPTIONS

                (a) Each option granted under the Plan shall be exercisable on
such date or dates and during such period and for such number of Shares as shall
be set forth in the instrument evidencing such option.

                (b) A person electing to exercise an option shall give written
notice to the Company of such election and the number of Shares such person has
elected to purchase and shall, at the time of exercise, tender the full purchase
price of the Shares such person has elected to purchase. Until such person has
been issued a certificate or certificates for the Shares so purchased, such
person shall possess no rights of a record holder with respect to any such
Shares.

        (c) No option shall be affected by any change of duties or position of
the optionee (including transfer to or from a subsidiary), so long as such
optionee continues to be an employee of the Company or one of its subsidiaries.
If an optionee shall cease to be an employee for any reason other than death,
the options held by such optionee shall thereafter be exercisable only to the
extent of the purchase rights, if any, which had accrued as of the date of such
cessation, provided that (i) the Committee may provide in the instrument
evidencing any option that the Committee may in its absolute discretion, upon
any such cessation of employment, determine (but shall be under no obligation to
determine) that such accrued purchase rights shall be deemed to include
additional Shares covered by such option and (ii) upon any such cessation of
employment, such accrued rights to purchase shall in any event terminate upon
the earlier of (A) the expiration of the full term of the option or (B) the
expiration of thirty (30) days from the date of such cessation of employment.
The instruments evidencing options granted under the Plan may contain such
provisions as the Committee shall approve with reference to the effect of
approved leaves of absence. Nothing in the Plan or in

                                      A-3

   4




any option granted hereunder shall confer upon any optionee any right to
continue in the employ of the Company or any of its subsidiaries, or to limit or
interfere in any way with the right of the Company or its subsidiaries to
terminate such optionee's employment at any time, with or without cause.

                (d) Should an optionee die while in the employ of the Company or
one of its subsidiaries, or within thirty (30) days after cessation of such
employment, such person as shall have acquired, by will or by the laws of
descent and distribution (the "personal representative"), the right to exercise
any option theretofore granted such optionee may, in either case, exercise such
option at any time prior to expiration of its full term or one year from the
date of death of the optionee, whichever is earlier, provided that any such
exercise shall be limited to the purchase rights which had accrued as of the
date when the optionee ceased to be an employee, whether by death or otherwise,
and provided further, however, that the Committee may provide in the instrument
evidencing any option that all Shares covered by such option shall become
subject to purchase immediately upon the death of the optionee.

                9.      SURRENDER OF OPTIONS

                The Committee may, under such terms and conditions as it deems
appropriate, accept the surrender by an optionee, or the personal representative
of an optionee, of an option, or any portion thereof, to purchase Shares granted
under the Plan and authorize the payment in consideration for such surrender of
an amount equal to the excess of the fair market value at the date of surrender
of the Shares covered by the option, or portion thereof, surrendered over the
aggregate option price of such Shares, such payment to be in Shares (valued at
fair market value on the date of such surrender) or in cash, or partly in Shares
and partly in cash, provided that the Committee determines that such settlement
is consistent with the purpose set forth in Section 1 hereof.

                10.     ADJUSTMENT UPON CHANGES IN CAPITALIZATION

                In the event of any change in the number of outstanding Shares
through the declaration of share dividends, share splits, or consolidations,
through recapitalizations, or by reason of any other increase or decrease in the
number of outstanding Shares effected without receipt of consideration by the
Company, the number of Shares available and reserved for options which may
thereafter be granted, the number of Shares reserved for and subject to any
options outstanding but unexercised, and the price per share payable on the
exercise of any options outstanding but unexercised, shall be adjusted as the
Committee considers appropriate, and all such adjustments by the Committee shall
be conclusive and binding upon all optionees under the Plan and upon any person
claiming under or through such an optionee.

                11.     AMENDMENT, SUSPENSION OR TERMINATION OF PLAN

                The Board of Directors may at any time terminate or from time to
time amend or suspend the Plan; provided, however, that no such amendment shall,
without approval of the shareholders of the Company, except as provided in
Section 10 hereof, (a) increase the aggregate number of Shares as to which
options may be granted under the Plan; (b) change the minimum option exercise
price; (c) increase the maxinium period during which options

                                      A-4

   5


may be exercised; (d) extend the effective period of this Plan; or (e) permit
the granting of options to members of the Committee. No option may be granted
during any suspension of the Plan or after the Plan has been terminated and no
amendment, suspension, or termination shall, without the optionee's consent,
alter or impair any of the rights or obligations under any option theretofore
granted to such person under the Plan.


               12.     EFFECTIVE DATE AND DURATION OF PLAN

                This Plan shall become effective upon its approval by the
affirmative vote of the holders of a majority of the outstanding Shares present
in person or by proxy and entitled to vote on this Plan at the Annual Meeting of
the Shareholders of the Company on September 28, 1979, or any adjournment
thereof. No options may be granted under this Plan subsequent to September 27,
1989.

                      1979 NON-QUALIFIED STOCK OPTION PLAN



        This Amendment No. 1 is made this 21st day of July, 1982 by
the Board of Directors of RPM, Inc. (hereinafter referred to as the
"Company");

                                  WITNESSETH:
                                  -----------

        WHEREAS, the RPM, Inc. 1979 Non-Qualified Stock Option Plan

1979; and

        WHEREAS, the Board of Directors is empowered under Section 11
of the Plan to amend and modify the Plan; and

        WHEREAS, it is the desire of the Board of Directors of the Company to

options" as defined in Section 422A of the Internal Revenue Code of 1954, as 
amended;

        NOW, THEREFORE, pursuant to Section 11 of the Plan, the Board of
Directors of the Company, hereby amends the Plan effective July 21, 1982 as
follows:

        (1) Section 3 of the Plan is hereby amended by the addition thereto of a
new final paragraph to read as follows:

         422A of Internal Revenue Code of 1954, as amended (the "Code"),
         hereinafter referred to as "incentive stock options", or non-qualified
         stock options as the Committee shall determine 

   7

         of an option which is an incentive stock option, such option shall not
         be exercisable by the optionee while any incentive stock option which
         was granted before the granting of such option has not been exercised
         in full or has not expired by reason of lapse of time."

                (2) Section 5 of the Plan is hereby amended by the deletion of
said Section and the substitution in lieu thereof of a new Section 5 to read as
follows:

               "5.     Term of Options

         such period as the Committee shall determine, but shall not be more
         than ten years from the date of granting thereof; provided, however,
         that if an employee to whom an incentive stock option is granted is at
         the time of grant of the incentive stock option an owner as defined in
         Section 425(d) of the Code of more than 10 percent of the total
         combined voting power of all classes of stock of the Company or any
         subsidiary corporation, hereinafter referred to as a "Substantial
         Shareholder," no incentive stock option granted to such an employee
         shall be exercisable after the expiration of five years from the date
         of grant of such option.

                  Each option shall be subject to earlier termination as
         provided in Paragraphs (c) and (d) of Section 8 and in Section 9 of the
         Plan.

                  The Committee may, with the concurrence of the affected
         optionee, cancel any option granted under the Plan and authorize the
         grant of a new option or options to buy Shares in such number and at
         such price as the Committee shall determine, subject to the provisions
         of the Plan."

         time any option is granted but shall not be less than 100 per cent of
         the fair market value of the Shares covered thereby at the time the
         option is granted, such fair market value to be determined in
         accordance with procedures to be established by the Committee;
         provided, however, that if an em-

         ployee to whom an incentive stock option is granted is at the time of
         the grant of the incentive stock option a Substantial Shareholder, the
         option price shall be determined by the Committee from time to time but
         shall never be less than 110 percent of the fair market value of the
         Company's Shares on the date such option is granted."

        (4) Section 8 of the Plan is hereby amended by the addition thereto of a
new Paragraph (e) to read as follows:

                  "(e) In the case of incentive stock options granted after
         December 31, 1980, the aggregate fair market value (determined as of
         the date the option is granted) of the Shares for which any key
         management employee may be granted incentive stock options in any
         calendar year shall not exceed $100,000 plus any unused limit carryover

        WHEREAS, the RPM, Inc. 1979 Non-Qualified Stock Option Plan (hereinafter
referred to as the "Plan") was established on September 28, 1979 to provide key
employees of the Company and its subsidiaries with greater incentive to serve

amend certain provisions of the Plan to enable participants to exercise stock
options granted under the Plan by delivering already-owned Common Shares of the
Company in payment therefor;

        NOW, THEREFORE, pursuant to Section 11 of the Plan, the Board of
Directors of the Company hereby amends the Plan, effective May 3, 1984, as

"(b) A person electing to exercise an option shall give written notice to the
Company of such election and the number of Shares such person has elected to
purchase and shall, at the time of exercise, tender the full purchase price of
the Shares such person has elected to purchase. With respect to incentive stock
options granted prior to May 3, 1984,the purchase price shall be paid in cash,
and with respect to incentive stock options granted thereafter and with respect
to any non-qualified stock options regardless of date of grant, the purchase
price may be paid either in cash or in the Company's Shares (excluding
fractional shares), or a combination thereof; provided, however, that the
practice known as "Pyramiding", which involves successive option exercises using
Shares received from a preceeding exercise to immediately exercise another
option and so on, shall not be permitted. Shares delivered in payment of the
purchase price shall be valued at the fair market value of such Shares on the
date of exercise of the option. Until such person has been issued a certificate
or certificates for the Shares so purchased, such person shall possess no rights
of record holder with respect to such Shares."

        WHEREAS, the RPM, Inc. 1979 Non-Qualified Stock Option Plan (hereinafter

        WHEREAS, it is the desire of the Board of Directors of the Company to
amend certain provisions of the Plan to reflect certain changes in the federal
tax laws resulting from the Tax Reform Act of 1986 by (i) deleting the provision
requiring the sequential exercise of options granted under the Plan, and (ii)
deleting the $100,000 limit on the aggregate fair market value for options

        (1) Section 3 of the Plan is hereby amended by the deletion of the last
paragraph of said Section in its entirety and the substitution in lieu thereof a
new final paragraph to read as follows:

         constitute either incentive stock options, as defined in Section 422A
         of Internal Revenue Code of 1954, as amended (the "Code"), hereinafter

                THIS AGREEMENT, entered into this ____ day of ________, 198__ ,
by and between RPM, Inc., an Ohio corporation (the "Company"), and __________ 
(the "Optionee).

                                  WITNESSETH:
                                  -----------

                WHEREAS, the Board of Directors of the Company has designated
the Compensation Committee of the Board of Directors (the "Committee") to serve
as the Committee to administer the Company's 1979 Non-Qualified Stock Option
Plan (the "Plan"), and

                WHEREAS, the Committee has determined that the Optionee, as an
employee of the Company or of one of its subsidiaries (an "Employee"), should be
granted an incentive stock option under the Plan upon the terms and subject to
the conditions and covering the number of Common Shares, without par value
("Shares"), of the Company, set forth hereinafter:

                NOW, THEREFORE, the Company and the Optionee hereby agree as
follows:

                1. Effective as of the date of this Agreement, the Company
grants to the Optionee, upon the terms and subject to the conditions set forth
hereinafter, the right and option to purchase all or any part of an aggregate of
_____ Thousand Shares (_,O0O) shares (such right and option being hereinafter
referred to as the "Option"), at a price of $_____ per share (the "Option
Price").

                2. The term of the option shall be for a period of ten (10)
years from the date hereof, and the Option shall expire at the close of regular
business hours at the Company's principal office, Medina, Ohio, on the last day
of the term of the Option, or, if earlier, on the applicable expiration date
provided for in paragraphs 4 and 5 hereof.

                3. Except as provided in paragraph 7 hereof, the Option shall
not be exercisable to any extent until one (1) year from the date hereof. The
Optionee shall become entitled to exercise the Option with respect to the number
of shares indicated below as of the date indicated opposite such number below:

        Number of Shares        Date as of Which
        as to Which Option      Option May be
        May be Exercised        Exercised
        ----------------        ---------
   17


To the extent that the Option has become exercisable with respect to a number of
Shares, as provided above, the Option may thereafter be exercised by the
Optionee either as to all or any part of such Shares at any time or from time to
time prior to expiration of the Option pursuant to paragraph 2 hereof. Except as
provided in paragraphs 4 and 5 hereof, the Option may not be exercised at any
time unless the Optionee shall be an Employee at such time.

                4. So long as the Optionee shall continue to be an Employee, the
Option shall not be affected by (a) any temporary leave of absence approved in
writing by the Company or one of its subsidiaries, or (b) any change of duties
or position (including transfer to or from a subsidiary). If the Optionee ceases
to be an Employee for any reason other than death, the Option may be exercised
only to the extent of the purchase rights, if any, which had accrued as of the
date of such cessation pursuant to paragraph 3 hereof and which have not
theretofore been exercised; provided, however, that the Committee may in its
absolute discretion determine (but shall be under no obligation to determine)
that such accrued purchase rights shall be deemed to include additional Shares
covered by the Option. Upon any such cessation of employment, by reason of
discharge, such accrued purchase rights shall in any event terminate upon the
earlier of the date thirty (30) days from the date of such cessation of
employment or the last day of the term of the Option. Upon any such cessation of
employment by reason of a voluntary quit, such accrued purchase rights shall
terminate on the date of such cessation of employment. Nothing contained in this
Agreement shall confer upon the Optionee any right to continue in the employ of
the Company or any of its subsidiaries, or to limit or interfere in any way with
the right of the Company or any such subsidiary to terminate his or her
employment at any time, with or without cause.

                5. If the Optionee dies while an Employee or within thirty (30)
days of the Optionee's having ceased to be an Employee for any reason, such
person or persons as shall have acquired, by will or by the laws of descent and
distribution, the right to exercise the Option (the "Personal Representative")
may exercise the Option to the extent of the purchase rights, if any, which had
accrued as of the date of the Optionee's death pursuant to paragraph 3 hereof
and which have not theretofore been exercised; provided, however, that the
Committee may in its absolute discretion determine (but shall be under no
obligation to determine) that such accrued purchase rights shall be deemed to
include additional Shares covered by the Option. Such accrued purchase rights
shall in any event terminate upon the earlier of the date one year from the date
of the Optionee's death or the last day of the term of the Option.

                6. Notwithstanding the foregoing, this Option is exercisable
only to the extent that the aggregate fair market value (determined at the time
such Option is granted) of the shares with respect to which such Options first
become exercisable during any calendar year does not exceed $100,000.

                7.      Upon the commencement of a "tender offer" for RPM, Inc. 
Common Shares as provided under Rule 14d-2 of the Securities Exchange Act of
1934, or any subsequent comparable Federal rule or regulation governing



                                      -2-

   18


tender offers in general, or upon the occurrence of a "Control Share
Acquisition" of RPM, Inc. Common Shares as defined under Section 1707.01(z),
Ohio Revised Code, or any subsequent comparable statutes under the laws of the
State of Ohio, whichever first occurs, the Optionee shall have the immediate
right and option (notwithstanding the provisions of paragraph 3 hereof) to
exercise the Option with respect to all Shares covered by the Option, which
exercise, if made, shall be irrevocable.

                8. In the event of any change in the number of outstanding
Shares through the declaration of share dividends, share splits, or
consolidations, through recapitalizations, or by reason of any other increase or
decrease in the number of outstanding Shares effected without receipt of
consideration by the Company, the number of Shares then covered by the Option
and the Option Price shall be appropriately adjusted consistent with such
change. The determination of the Committee as to any such adjustment shall be
conclusive and binding upon the Optionee and upon the Personal Representative.

                9. The Option may be exercised by delivery to the Secretary of
the Company at its principal office, 2628 Pearl Road, P.O. Box 777, Medina, Ohio
44258, of a completed Notice of Exercise of Option (obtainable from the
Secretary of the Company) setting forth the number of Shares with respect to
which the Option is being exercised, together with a certified or cashier's
check payable to the Company in the amount of the total purchase price of such
Shares.

                10. Upon receipt by the Company prior to expiration of the
Option of a duly completed Notice of Exercise of Option accompanied by a
certified or cashier's check , as provided in paragraph 9 hereof, in full
payment for the Shares being purchased pursuant to such Notice (and, with
respect to any Option exercised pursuant to paragraph 5 hereof by the Personal
Representative, accompanied in addition by proof satisfactory to the Committee
of the right of the Personal Representative to exercise the Option), the Company
shall cause to be mailed or otherwise delivered to the Optionee or the Personal
Representative, as the case may be, within thirty (30) days of such receipt, a
certificate or certificates for the number of Shares so purchased. The Optionee
or the Personal Representative shall not have any of the rights of a shareholder
with respect to the Shares covered by the Option unless and until one or more
certificates representing such Shares shall be issued to the Optionee or the
Personal Representative.

                11. The Committee may, under such terms and conditions as it
deems appropriate, accept the surrender by the Optionee or by the Personal
Representative of the right to exercise the Option with respect to all or part
of the Shares subject to the Option and authorize a payment in consideration
therefor of an amount equal to the difference obtained by subtracting the Option
Price for such Shares from the fair market value of such Shares (being the last
sales price of the Shares on the date of such surrender as reported on NASDAQ),
such payment to be made in cash, or in Shares valued at fair market value (as
defined above in this paragraph 11) as of the date of such surrender, or partly
in cash and




                                      -3-


   19

partly in Shares, provided that the Committee determines that such settlement is
consistent with the purpose of the Plan. The Option, or part thereof, which is
surrendered pursuant to this paragraph 11 shall terminate as of the date of such
surrender.

        12. This Agreement shall be binding upon and inure to the benefit of any
successor or successors of the Company and the heirs, estate and personal
representatives of the Optionee. The Option shall not be transferable other than
by will or the laws of descent and distribution, and the Option may be exercised
during the lifetime of the Optionee only by the Optionee.

        13. This Agreement is subject to all of the terms, conditions, and
provisions of the RPM, Inc. 1979 Non-Qualified Stock Option Plan, as amended
from time to time, and to such rules, regulations, and interpretations of the
Plan as may be adopted by the Committee and in effect from time to time. A copy
of the Plan is attached hereto as Exhibit "A" and is incorporated herein by
reference. In the event and to the extent that this Agreement conflicts or is
inconsistent with the terms, conditions, and provisions of the Plan, the Plan
shall control, and this Agreement shall be deemed to be modified accordingly.

        IN WITNESS WHEREOF, the Company has caused this Agreement to be executed
on its behalf by its undersigned officer thereunto duly authorized, and the
Optionee has hereunto set his hand, all as of the day and year first above
written.
