                                MASCO CORPORATION
                             1988 STOCK OPTION PLAN

                    (Amended and Restated September 22, 1999)

ARTICLE I.  PURPOSE

         The purpose of the 1988 Stock Option Plan (the "Plan") is to secure for
Masco Corporation (the "Company") and its stockholders the benefits inherent in
stock ownership by selected key employees of and consultants to the Company and
its subsidiaries and affiliated companies who in the judgment of the committee
responsible for the administration of the Plan are largely responsible for the
Company's growth and success. The Plan is designed to accomplish this purpose by
offering such employees and consultants an opportunity to purchase shares of the
Common Stock of the Company. For purposes of the Plan a "subsidiary" is any
corporation in which the Company owns, directly or indirectly, stock possessing
more than fifty percent of the total combined voting power of all classes of
stock, and an "affiliated company" is any other corporation, at least twenty
percent of the total combined voting power of all classes of stock of which is
owned by the Company or by one or more other corporations in a chain of
corporations, at least twenty percent of the stock of each of which is held by
the Company or a subsidiary or another corporation within such chain.

ARTICLE II.  ADMINISTRATION

         The Plan shall be administered by a committee (the "Committee") of
three or more of the Company's directors to be appointed by the Board of
Directors. Members of the Committee shall be "disinterested persons" as such
term is defined in Rule 16b-3(d) under the Securities Exchange Act of 1934 (the
"Exchange Act") or any rule which modifies, amends or replaces Rule 16b-3(d).
The Committee shall have authority, consistent with the Plan:

                  (a) to determine which key employees of and consultants to the
         Company, its subsidiaries and affiliated companies shall be granted
         options;

                  (b) to determine the time or times when options shall be
         granted and the number of shares of Common Stock subject to each
         option;

                  (c) to determine the option price of the stock subject to each
         option and the method of payment of such price;

                  (d) to determine the time or times when each option becomes
         exercisable, limitations on exercise, and the duration of the exercise
         period;

                  (e) to prescribe the form or forms of the instruments
         evidencing options granted under the Plan and of any other instruments
         required under the Plan, and to change such forms from time to time;

<PAGE>   2

                  (f) to designate options granted to key employees of the
         Company or its subsidiaries under the Plan as "incentive stock options"
         ("ISOs"), as such terms are defined in the Internal Revenue Code of
         1986;

                  (g) to adopt, amend and rescind rules and regulations for the
         administration of the Plan and options and for its own acts and
         proceedings; and

                  (h) to decide all questions and settle all controversies and
         disputes which may arise in connection with the Plan.

         All decisions, determinations and interpretations of the Committee
shall be conclusive and binding on all parties concerned.

ARTICLE III.  PARTICIPANTS

         Key employees of and consultants to the Company, its subsidiaries and
affiliated companies, including officers of the Company (who may also be
directors, but excluding members of the Committee, any person who serves only as
a director of the Company and any consultant to the Company or any of its
subsidiaries or affiliated companies who is also a director of the Company or
who is not rendering services pursuant to a written agreement with the
corporation in question), as may be selected from time to time by the Committee
in its discretion, are eligible to receive options under the Plan. The grant of
an option to an employee or consultant shall not entitle such individual to
other grants or options, nor shall such grant disqualify such individual from
further participation.

ARTICLE IV.   LIMITATIONS

         No options shall be granted under the Plan after December 31, 1998, but
options theretofore granted may extend beyond that date. Subject to adjustment
as provided in Article IX, the number of shares of Common Stock of the Company
which may be issued under the Plan shall not exceed 8,000,000; provided,
however, that such number of shares shall be reduced by the number of shares of
the Company's Common Stock awarded under the Company's 1988 Restricted Stock
Incentive Plan (other than shares awarded under such plan which are later
forfeited to the Company). To the extent that any option granted under the Plan
shall expire or terminate unexercised or for any reason become unexercisable,
any stock theretofore subject to such expired or terminated option shall
thereafter be available for further grants under the Plan. If an option granted
under the Plan shall be accepted for surrender pursuant to Article VIII, any
stock subject to such option shall not thereafter be available for further
grants.

         Notwithstanding any provision to the contrary in the Plan, no option
may be designated an ISO unless all of the following conditions are satisfied:

                                      -2-
<PAGE>   3

                  (a) Such option must be granted on or prior to April 1, 1998,
         and such option by its terms must not be exercisable after the
         expiration of ten years from the date such option is granted;

                  (b) Either (i) the employee to whom such option is granted
         does not, determined at the time such option is granted, own capital
         stock representing more than ten percent of the voting power of all
         classes of stock of the Company, its parent or any of its subsidiaries,
         or (ii) the option price is at least 110 percent of the fair market
         value, determined at the time such option is granted, of the stock
         subject to such option and such option by its terms is not exercisable
         more than five years from the date it is granted; and

                  (c) The aggregate fair market value of the Common Stock
         subject to such option plus the aggregate fair market value of Common
         Stock subject to ISOs previously or concurrently granted to the same
         employee exercisable in the same calendar year (all determined at the
         respective dates of grant of such options) must not exceed $100,000.

ARTICLE V.  STOCK TO BE ISSUED

         The stock as to which options may be granted is the Company's Common
Stock, $1 par value. Such stock may be authorized but unissued shares or shares
of Common Stock reacquired by the Company, including but not limited to shares
purchased on the open market. The Board of Directors and the officers of the
Company shall take any appropriate action required for such issuance.

ARTICLE VI. TERMS AND CONDITIONS OF OPTIONS

         All options granted under the Plan shall be subject to the following
terms and conditions (except as otherwise provided in Article VII) and to such
other terms and conditions as the Committee shall deem appropriate.

         (a) Option Price. Each option shall have such per share option price as
the Committee may determine, but not less than the fair market value of Common
Stock of the Company on the date the option is granted.

         (b) Term of Options. The term of an option shall not exceed eleven
years from the date of grant. The date of grant shall be the date on which the
option is awarded by the Committee.

         (c) Exercise of Options.

                  (i) Each option shall be made exercisable not less than six
         months from the date of grant and at such time or times, whether or not
         in installments, as the Committee shall prescribe at the time the
         option is granted.

<PAGE>   4

                  (ii)  A person electing to exercise an option shall give
         written notice to the Company, as may be specified by the Committee, of
         exercise of the option and the number of shares of stock elected for
         exercise, such notice to be accompanied by such instruments or
         documents as may be required by the Committee, and shall tender the
         purchase price of the stock elected for exercise unless otherwise
         directed by the Committee.

                  (iii) (A) Notwithstanding any of the provisions of this Plan
         or instruments evidencing options granted hereunder, in the case of a
         Change in Control of the Company, each option then outstanding shall
         immediately become exercisable in full. A Change in Control shall occur
         if any of the events described below in subparagraphs (1), (2) or (3)
         shall have occurred, unless the holder of any such option shall have
         consented to the application of subparagraph (3) in lieu of
         subparagraphs (1) and (2):

                       (1) any "person" or "group of persons" as such terms are
                  used in Sections 13(d) and 14(d) of the Exchange Act other
                  than pursuant to a transaction or agreement previously
                  approved by the Board of Directors directly or indirectly
                  purchases or otherwise becomes the "beneficial owner" (as
                  defined in Rule 13d-3 under the Exchange Act) or has the right
                  to acquire such beneficial ownership (whether or not such
                  right is exercisable immediately, with the passage of time, or
                  subject to any condition) of voting securities representing
                  25% or more of the combined voting power of all outstanding
                  voting securities of the Company;

                       (2) during any period of twenty-four consecutive calendar
                  months, the individuals who at the beginning of such period
                  constitute the Company's Board of Directors, and any new
                  directors whose election by such Board or nomination for
                  election by stockholders was approved by a vote of at least
                  two-thirds of the members of such Board who were either
                  directors on such Board at the beginning of the period or
                  whose election or nomination for election as directors was
                  previously so approved, for any reason cease to constitute at
                  least a majority of the members thereof; or

                       (3) during any period of twenty-four consecutive calendar
                  months, the individuals who at the beginning of such period
                  constitute the Company's Board of Directors, and any new
                  directors (other than Excluded Directors, as hereinafter
                  defined), whose election by such Board or nomination for
                  election by stockholders was approved by a vote of at least
                  two-thirds of the members of such Board who were either
                  directors on such Board at the beginning of the period or
                  whose election or nomination for election as directors was
                  previously so approved, for any reason cease to constitute at
                  least a majority of the members thereof. For purposes hereof,
                  "Excluded Directors" are directors whose election by the Board
                  or approval by the Board for stockholder election occurred
                  within one year of any "person" or "group of persons", as such
                  terms are used in Sections 13(d) and 14(d) of the Exchange
                  Act, commencing a tender offer for, or becoming the beneficial
                  owner of, voting securities representing 25 percent or more of
                  the combined voting power of all outstanding voting securities
                  of the Company, other than pursuant to a tender offer approved
                  by the Board prior

                                      -4-

<PAGE>   5

                  to its commencement or pursuant to stock acquisitions approved
                  by the Board prior to their representing 25 percent or more of
                  such combined voting power.

                  (B)(1) In the event that subsequent to a Change in Control it
         is determined that any payment or distribution by the Company to or for
         the benefit of a participant, whether paid or payable or distributed or
         distributable pursuant to the terms of this Plan or otherwise, other
         than any payment pursuant to this subparagraph (B) (a "Payment"), would
         be subject to the excise tax imposed by Section 4999 of the Internal
         Revenue Code of 1986, as amended from time to time ("Code"), or any
         interest or penalties with respect to such excise tax (such excise tax,
         together with any such interest and penalties, are hereinafter
         collectively referred to as the "Excise Tax"), then such participant
         shall be entitled to receive from the Company, within 15 days following
         the determination described in (2) below, an additional payment
         ("Excise Tax Adjustment Payment") in an amount such that after payment
         by such participant of all applicable Federal, state and local taxes
         (computed at the maximum marginal rates and including any interest or
         penalties imposed with respect to such taxes), including any Excise
         Tax, imposed upon the Excise Tax Adjustment Payment, such participant
         retains an amount of the Excise Tax Adjustment Payment equal to the
         Excise Tax imposed upon the Payments.

                  (2) All determinations required to be made under this Article
         VI(c)(iii)(B), including whether an Excise Tax Adjustment Payment is
         required and the amount of such Excise Tax Adjustment Payment, shall be
         made by PricewaterhouseCoopers LLP, or such other national accounting
         firm as the Company, or, subsequent to a Change in Control, the Company
         and the participant jointly, may designate, for purposes of the Excise
         Tax, which shall provide detailed supporting calculations to the
         Company and the affected participant within 15 business days of the
         date of the applicable Payment. Except as hereinafter provided, any
         determination by PricewaterhouseCoopers LLP, or such other national
         accounting firm, shall be binding upon the Company and the participant.
         As a result of the uncertainty in the application of Section 4999 of
         the Code that may exist at the time of the initial determination
         hereunder, it is possible that (x) certain Excise Tax Adjustment
         Payments will not have been made by the Company which should have been
         made (an "Underpayment"), or (y) certain Excise Tax Adjustment Payments
         will have been made which should not have been made (an "Overpayment"),
         consistent with the calculations required to be made hereunder. In the
         event of an Underpayment, such Underpayment shall be promptly paid by
         the Company to or for the benefit of the affected participant. In the
         event that the participant discovers that an Overpayment shall have
         occurred, the amount thereof shall be promptly repaid to the Company.

                  (3) This Article VI(c)(iii)(B) shall not apply to any option
         that was granted to an executive officer of the Company, as determined
         under the Exchange Act.

         (d) Payment for Issuance of Stock. At the time of exercise of any
option granted pursuant to the Plan, payment in full shall be made for all stock
then being purchased either in cash or, at the discretion of the Committee, in
whole or in part in Common Stock of the Company valued at its then fair market
value. Notwithstanding the foregoing, the Committee may in its discretion permit
the

                                      -5-

<PAGE>   6

issuance of stock upon such other plan of payment as it deems reasonable,
provided that the then unpaid portion of the purchase price shall be evidenced
by a promissory note at such rate of interest and upon such other terms and
conditions as the Committee shall deem appropriate. In all cases where stock is
issued for less than present full payment of the purchase price, there shall be
placed upon the certificate or certificates representing such stock a legend
setting forth the amount paid at issuance, and the amount remaining unpaid
thereon, and stating that the stock is subject to call for the remainder and may
not be transferred by the holder until the balance due thereon shall be fully
paid.

         The Committee, in its discretion and in accordance with its procedures,
may permit a participant to satisfy, in whole or in part, the income tax
withholding obligations in connection with the exercise of a non-qualified stock
option by having shares withheld from the shares to be issued upon the exercise
of the option or by delivering shares of Common Stock of the Company having a
fair market value equal to the amount needed to satisfy such obligations.

         (e) Conditions to Issuance. The Company shall not be obligated to issue
any stock unless and until:

                  (i)  if the Company's outstanding Common Stock is at the time
         listed upon any stock exchange, the shares of stock to be issued have
         been listed, or authorized to be added to the list upon official notice
         of issuance, upon such exchange, and

                  (ii) in the opinion of the Company's counsel there has been
         compliance with applicable law in connection with the issuance and
         delivery of stock and such issuance shall have been approved by the
         Company's counsel.

Without limiting the generality of the foregoing, the Company may require from
the participant such investment representation or such agreement, if any, as
counsel for the Company may consider necessary in order to comply with the
Securities Act of 1933 as then in effect, and may require that the participant
agree that any sale of the stock will be made only in such manner as shall be in
accordance with law and that the participant will notify the Company of any
intent to make any disposition of the stock whether by sale, gift or otherwise.
The participant shall take any action reasonably requested by the Company in
such connection. A participant shall have the rights of a stockholder only as
and when shares of stock have been actually issued to the participant pursuant
to the Plan.

         (f) Limits on Transferability of Options. No option may be transferred
by the participant other than (i) by designation of beneficiary as provided in
subsection (j) of this Article, or (ii) by will or the laws of descent and
distribution, or (iii) to a revocable grantor trust established by the
participant for the sole benefit of the participant during the participant's
life, and under the terms of which the participant is and remains the sole
trustee until death or physical or mental incapacity. Such assignment shall be
effected by a written instrument in form and content satisfactory to the
Committee, and the participant shall deliver to the Committee a true copy of the
agreement or other document evidencing such trust. If in the judgment of the
Committee the trust to which a participant may attempt to assign rights under
such an Award does not meet the criteria of a trust to which an

                                      -6-

<PAGE>   7

assignment is permitted by the terms hereof, or if after assignment, because of
amendment, by force of law or any other reason such trust no longer meets such
criteria, such attempted assignment shall be void and may be disregarded by the
Committee and the Company and all rights to any such Options shall revert to and
remain solely in the participant. Notwithstanding a qualified assignment, the
participant, and not the trust to which rights under such an Option may be
assigned, for the purpose of determining compensation arising by reason of the
Option, shall continue to be considered an employee or consultant, as the case
may be, of the Company or an affiliated company, but such trust and the
participant shall be bound by all of the terms and conditions of this Plan and
any written agreement, contract or other instrument or document evidencing any
award granted under this Plan. Shares issued in the name of and delivered to
such trust shall be conclusively considered issuance and delivery to the
participant.

         (g) Consideration for Option. Each person receiving an option must
agree to remain as an employee or consultant upon the terms of employment or the
consulting arrangement then existing (unless different terms are mutually agreed
upon) for at least ninety days from the date the option is granted.

         (h) Termination of Employment. If the employment of or consulting
arrangement with a participant terminates for any reason (including termination
by reason of the fact that any corporation is no longer a subsidiary or
affiliated company) other than the participant's death or permanent and total
disability or, in the case of an employee, retirement on or after normal
retirement date, unless discharged for misconduct which in the opinion of the
Committee casts such discredit on the participant as to justify termination of
the option, the participant may thereafter exercise the option as provided
below. If such termination is voluntary on the part of the participant, the
option may be exercised only within ten days after the day of termination. If
such termination is involuntary on the part of the participant, the option may
be exercised within three months after the day of termination. Except as
expressly provided in the Plan or the option, whether the termination of
employment or consulting arrangement is voluntary or involuntary, options may be
exercised only if such options were exercisable at the date of such termination,
and an option may not be exercised at a time when the option would not have been
exercisable had the employment or consulting arrangement continued.
Notwithstanding the preceding three sentences, the Committee may extend the time
within which or alter the terms and conditions on which the participant may
exercise an option after the termination of employment or the consulting
arrangement, and if the period within which an option may be exercised has been
extended, the Committee may terminate the unexercised portion of the option if
it shall determine that the participant has engaged in any activity detrimental
to the Company's interests. For purposes of this Article VI(h), a participant's
employment or consulting arrangement shall not be considered terminated (i) in
the case of approved sick leave or other bona fide leave of absence (not to
exceed one year unless otherwise approved by the Committee), (ii) in the case of
a transfer of employment or the consulting arrangement among the Company, its
subsidiaries and affiliated companies, or (iii) by virtue of a change of status
from employee to consultant or from consultant to employee.

         (i) Retirement; Disability. If prior to the expiration date of an
option the employee shall retire on or after normal retirement date or if the
employment or consulting relationship is terminated by reason of permanent and
total disability, such option may be exercised to the extent exercisable

                                      -7-

<PAGE>   8

on the date of retirement or such termination, provided such option shall be
exercised within three months of the date of retirement or such termination.
Notwithstanding the foregoing, in its discretion the Committee may extend the
time within which or alter the terms and conditions on which an option held by a
retired or disabled option holder may be exercised, and if the period within
which an option may be exercised has been extended, the Committee may terminate
the unexercised portion of the option if it shall determine that the participant
has engaged in any activity detrimental to the Company's interests.

         (j) Death. If a participant dies at a time when entitled to exercise an
option, then at any time or times within one year after death (or such further
period as the Committee may allow) such option may be exercised, as to all or
any of the shares which the participant was entitled to purchase immediately
prior to death (or such additional shares covered by the option as the Committee
may allow), by the person or persons designated in writing by the participant in
such form of beneficiary designation as may be approved by the Company, or
failing designation by the participant's personal representative, executor or
administrator or the person or persons to whom the option is transferred by will
or the applicable laws of descent and distribution. The Company may decline to
deliver shares to a designated beneficiary until it receives indemnity against
claims of third parties satisfactory to the Company. Except as so exercised such
option shall expire at the end of such period.

ARTICLE VII.  REPLACEMENT OPTIONS

         The Committee may grant options under the Plan on terms and conditions
differing from those provided for in Article VI where such options are granted
in substitution for options held by employees of or consultants to other
entities who concurrently become employees of or consultants to the Company or a
subsidiary or an affiliated company as the result of a merger, consolidation or
other reorganization of such other entity with the Company or a subsidiary or an
affiliated company, or the acquisition by the Company or a subsidiary or an
affiliated company of the business, property or stock of such other entity. The
Committee may direct that the replacement options be granted on such terms and
conditions as the Committee considers appropriate in the circumstances.

ARTICLE VIII. SURRENDER OF OPTIONS

         The Committee may, in its discretion and upon such terms and conditions
as it deems appropriate, accept the surrender by a participant of a presently
exercisable right to purchase stock granted under an option and authorize
payment by the Company in consideration therefor of an amount equal to the
difference obtained by subtracting the option price of the stock from its fair
market value on the date of such surrender, such payment to be in cash or shares
of the Common Stock of the Company valued at fair market value on the date of
such surrender, or partly in such stock and partly in cash, provided that the
Committee determines such settlement is consistent with the purpose of the Plan.

                                      -8-

ARTICLE IX.  CHANGES IN STOCK

         The Board of Directors is authorized to make such adjustments, if any,
as it shall deem appropriate in the number and kind of shares which may be
granted under the Plan, the number and kind of shares which are subject to
options then outstanding and the purchase price of shares subject to such
outstanding options, in the event of any change in capital or shares of capital
stock, any special distribution to stockholders or any extraordinary transaction
(including a merger, consolidation or dissolution) to which the Company is a
party. The determination of the Board of Directors as to such matters shall be
conclusive and binding on all persons.

ARTICLE X.   EMPLOYMENT RIGHTS

         The adoption of the Plan, the grant of options hereunder and the
participation by a participant in the Plan do not confer upon any employee of or
consultant to the Company or subsidiary or an affiliated company any right to
continue the employment or consulting relationship with the Company or a
subsidiary or an affiliated company, as the case may be, nor does it in any way
impair the right of the Company or a subsidiary or an affiliated company to
terminate the employment of any of its employees or the consulting arrangement
with any of its consultants at any time, with or without cause, unless a written
employment or consulting agreement provides otherwise.

 ARTICLE XI. AMENDMENTS

         The Board of Directors may at any time or times amend the Plan or amend
any outstanding option or options for the purpose of satisfying the requirements
of changes in applicable laws or regulations or for any other purpose which may
at the time be permitted by law, provided that except to the extent permitted
under Article IX, without the approval of the stockholders of the Company no
amendment shall increase the maximum number of shares of stock available under
the Plan, alter the class of persons eligible to receive options under the Plan,
or without the consent of the participant void or diminish options previously
granted, nor increase or accelerate the conditions required for the exercise of
the same, except that nothing herein shall limit the Company's right under
Article VI(d) to call stock, issued for deferred payment which is evidenced by a
promissory note, where the participant is in default of the obligations of such
note.

                                February 28, 1995

Dear

         As you know, our company's Board of Directors has adopted a Plan
whereby supplemental retirement and other benefits, in addition to those
provided under the Company's pension and other benefit plans, will be made
available to those Company and subsidiary executives as may be designated from
time to time by the company's Chief Executive Officer. You have been previously
designated as a participant in the Plan by a letter agreement signed by you and
dated December 10, 1992. This agreement amends and replaces in its entirety your
previously signed letter agreement and describes in full your benefits pursuant
to the Plan and all of the Company's obligations to you and yours to the Company
under the Plan. These benefits as described below are contractual obligations of
the Company.

     For the purposes of this Agreement, words and terms are defined as follows:

         a.   "Retirement" shall mean your termination of employment with the
              Company, on or after you attain age 65. Your acting as a
              consultant shall not be considered employment.

         b.   "Average Compensation" shall mean the aggregate of your highest
              three years' total annual cash compensation paid to you by the
              Company, consisting of (i) base salaries and (ii) regular year-end
              cash bonuses paid with respect to the years in which such salaries
              are paid, divided by three.

         c.   If you become Disabled, "Total Compensation" shall mean your
              annual base salary rate in the year in which you become Disabled
              plus the regular year-end cash bonus paid to you for the year
              immediately prior thereto.

         d.   "Surviving Spouse" shall be the person to whom you shall be
              legally married (under the law of the jurisdiction of your
              permanent residence) at the date of (i) your Retirement or death
              after attaining age 65 (if death terminated employment with the
              Company) for the purposes of paragraphs 1, 2 and 3, (ii) your
              death for the purposes of paragraph 5, and (iii) your Disability
              for the purposes of paragraphs 6 and 7. For the purposes of
              paragraphs 10a, 10e, 10f, 10g and 10h, "Surviving Spouse" shall be
              any spouse entitled to survivor's benefits.

         e.   "Disability" and "Disabled" shall mean your being unable to
              perform your duties as a Company executive by reason of your
              physical or mental condition, prior to your attaining age 65,
              provided that you have been employed by the Company for two
              consecutive Years or more.

         f.   "Company" shall mean MascoTech, Inc. or any corporation in which
              MascoTech, Inc. or a subsidiary owns stock possessing at least 20%
              of the total combined voting power of all classes of stock.

         g.   "Year" shall mean twelve full consecutive months, and "year" shall
              mean a calendar year.

         h.   "Plan Limitation" for any year shall mean (x) for 1989, $300,000
              multiplied by the Cost of Living Factor for 1988, and (y) for any
              year subsequent to 1989, the Plan Limitation for the immediately
              preceding year multiplied by the Cost of Living Factor for such
              preceding year.

         i.   "Cost of Living Factor" for any year shall mean, except as
              otherwise provided generally with respect to the Plan by the
              Company's Board of Directors, the quotient (in no event to exceed
              1.03 or to be less than .97) obtained by dividing the monthly
              Consumer Price Index Number (as compiled in the Consumer Price
              Index for Urban Consumers by the Bureau of Labor Statistics) for
              the month of December in such year by the monthly Consumer Price
              Index Number for the immediately preceding month of December.

         j.   A "Change in Control" shall be deemed to have occurred if, during
              any period of twenty-four consecutive calendar months, the
              individuals who at the beginning of such period constitute the
              Company's Board of Directors, and any new directors whose election
              by such Board or nomination for election by stockholders was
              approved by a vote of at least two-thirds of the members of such
              Board who were either directors on such Board at the beginning of
              the period or whose election or nomination for election as
              directors was previously so approved, for any reason cease to
              constitute at least a majority of the members thereof.

     1. In accordance with the Plan, upon your Retirement the Company will pay
you annually during your lifetime 60% of your Average Compensation, less: (i) a
sum equal to the annual benefit which would be payable to you upon your
Retirement if benefits payable to you under the Company funded qualified pension
plans and the defined benefit (pension) plan restoration provisions of the
Company's Retirement Benefits Restoration Plan and any similar plan were
converted to a life annuity, or if you are married when you retire, to a joint
and spouse survivor life annuity, (ii) a sum equal to the annual benefit which
would be payable to you upon Retirement if your vested accounts in the Company's
Future Service Profit Sharing Trust and the defined contribution (profit
sharing) restoration provisions of the Company's Retirement Benefits Restoration
Plan and any similar plan were converted to a life annuity, and (iii) any
retirement benefits payable to you by reason of employment by your prior
employers (excluding, however, from such deduction any portion thereof, and
earnings thereon, determined by the committee referred to in paragraph 10 to
have been contributed by you rather than your prior employers). In all cases the
amount offset pursuant to these subsections (i) and (ii) shall be determined
prior to the effect of any payments from the plans and trust referred to therein
which are authorized pursuant to a Qualified Domestic Relations Order under
ERISA.

                                      -2-

     2. Upon your death after Retirement or while employed by the Company after
attaining age 65, your Surviving Spouse shall receive for life 75% of the annual
benefit pursuant to paragraph 1 of this Agreement which was payable to you prior
to your death (or, if death terminated employment after attaining age 65, which
would have been payable to you had your Retirement occurred immediately prior to
your death).

     3. Upon your Retirement the Company will provide or purchase for you and
your spouse's benefit, or at its option reimburse you or your Surviving Spouse
for premiums paid, during your joint and several lives, such supplemental
medical insurance as the Company may deem advisable from time to time.

    4. Under no circumstances (i) will any retirement benefits be paid to you or
your Surviving Spouse pursuant to this Agreement unless you were employed by the
Company or Disabled on your Retirement, or were employed by the Company at the
time of your death after attaining age 65, and (ii) will you or your Surviving
Spouse be entitled to receive retirement benefits under this Agreement if your
Retirement commences prior to your attaining age 65.

     5. If while employed by the Company you die prior to your attaining age 65
leaving a Surviving Spouse, and provided you shall have been employed by the
Company for two consecutive Years or more, your Surviving Spouse shall receive
annually for life 45% of your Average Compensation, less: (i) a sum equal to the
annual benefit which would be payable to your Surviving Spouse under Company
funded qualified pension plans and the defined benefit (pension) plan
restoration provisions of the Company's Retirement Benefits Restoration Plan and
any similar plan if such benefit were converted to a life annuity, and (ii) a
sum equal to the annual payments which would be received by your Surviving
Spouse as if your spouse were designated as the beneficiary of your vested
accounts in the Company's Future Service Profit Sharing Trust and the defined
contribution (profit sharing) restoration provisions of the Company's Retirement
Benefits Restoration Plan and any similar plan and such accounts were converted
to a life annuity. In all cases the amount offset pursuant to these subsections
(i) and (ii) shall be determined prior to the effect of any payments from the
plans and trust referred to therein which are authorized pursuant to a Qualified
Domestic Relations Order under ERISA. No death benefits are payable except to
your Surviving Spouse.

     6. If you shall have been employed by the Company for two Years or more and
while employed by the Company you become Disabled prior to your attaining age
65, until the earlier of your death, termination of Disability or attaining age
65 the Company will pay you an annual benefit equal to 60% of your Total
Compensation less any benefits payable to you pursuant to long-term disability
insurance or other plans the cost of which is paid by the Company. If your
Disability continues until you attain age 65, you shall be considered retired
and you shall receive retirement benefits pursuant to paragraph 1 above, based
upon your Average Compensation as of the date it is determined you became
Disabled.

                                      -3-
<PAGE>   4

     7. If you die leaving a Surviving Spouse while receiving Disability
benefits pursuant to paragraph 6 of this Agreement, notwithstanding paragraph 4
you will be deemed to have retired on your death and your Surviving Spouse shall
receive for life 75% of the annual benefit which would have been payable to you
if you had retired on the date of your death and your benefit determined
pursuant to paragraph 1, based upon your Average Compensation as of your
becoming Disabled.

     8. Notwithstanding any of the provisions of this Agreement, the maximum
retirement, disability and death benefits payable to you and your spouse
pursuant to this Agreement for any year shall in no event exceed the higher of
(A) $500,000 less those sums to be deducted from benefits pursuant to clauses
(i), (ii) and (iii) of paragraph 1, clauses (i) and (ii) of paragraph 5, or
under paragraph 6, whichever is applicable, or (B) the Plan Limitation for the
year in which such benefits were first paid, less the aggregate annual benefit
with respect to the Company's Retirement Benefits Restoration Plan (and any
future non-qualified retirement plan) to be deducted (x) under clauses (i) and
(ii) of paragraph 1, (y) under paragraph 5 should you die while employed prior
to attaining age 65 or (z) under paragraph 6 should you become disabled prior to
attaining age 65.

     9. If you are eligible to receive benefits hereunder, unless otherwise
specifically agreed by the Company in writing, you will not be able to receive
benefits under any other Company sponsored non-qualified retirement plans other
than the Company's Retirement Benefits Restoration Plan.

     10. We also agree upon the following:

         a.   The Compensation Committee of the company's Board of Directors, or
              any other committee however titled which shall be vested with
              authority with respect to the compensation of the company's
              officers and executives, shall have the exclusive authority to
              make all determinations which may be necessary in connection with
              this Agreement including the date of and whether you are Disabled,
              the amount of annual benefits payable to you by reason of
              employment by other employers, the interpretation of this
              Agreement, and all other matters or disputes arising under this
              Agreement. The determinations and findings of the Compensation
              Committee or such other committee of the company's Board of
              Directors shall be conclusive and binding, without appeal, upon
              both of us.

         b.   You will not during your employment or Disability, and after
              Retirement or the termination of your employment, for any reason
              disclose or make use of for your own or another person's benefit
              under any circumstances any of the Company's Proprietary
              Information. Proprietary Information shall include trade secrets,
              secret processes, information concerning products, developments,
              manufacturing techniques, new product or marketing plans,
              inventions, research and development information or results,
              sales, pricing and financial data, information relating to the
              management, operations or planning of the Company and any other
              information treated as confidential or proprietary.

                                      -4-
<PAGE>   5

         c.   If your employment by the Company shall terminate for any reason
              whatsoever prior to your Retirement other than by reason of your
              death or Disability, for a period of two years after the
              termination of your employment, and if your employment shall be
              terminated by reason of Retirement or any Disability during such
              time as you shall receive retirement or disability benefits
              pursuant to this Agreement, you agree that you will not directly
              or indirectly engage in any business activities, whether as a
              consultant, advisor or otherwise, in which the Company is engaged
              in any geographic area in which the products or services of the
              Company have been sold, distributed or provided during the five
              year period prior to the date of termination of employment or
              Retirement.

              In addition to the foregoing and provided no "Change in Control"
              has occurred, if while you are receiving retirement or other
              benefits pursuant to this Agreement, in the judgment of the
              committee you directly or indirectly engage in activity or act in
              a manner which can be considered adverse to the interest of the
              Company or any of its direct or indirect subsidiaries or
              affiliated companies, the committee may terminate your rights to
              any further benefits hereunder.

         d.   Except as may be provided to the contrary in a duly authorized
              written agreement between yourself and the Company you acknowledge
              that the Company has made no commitments to you of any kind with
              respect to the continuation of your employment, which we expressly
              agree is an employment at will, and you or the Company shall have
              the unrestricted right to terminate your employment with or
              without cause, at any time in your or its discretion.

         e.   At the Company's request, expressed through a Company officer, you
              agree to provide such information with respect to matters which
              may arise in connection with this Agreement as may be deemed
              necessary by the Company or the Compensation or other committee,
              including for example only and not in limitation, information
              concerning benefits payable to you from third parties, and you
              further agree to submit to such medical examinations by duly
              licensed physicians as may be requested by the Company or such
              committee from time to time. You also agree to direct third
              parties to provide such information, and your Surviving Spouse's
              cooperation in providing such information is a condition to the
              receipt of survivor's benefits under this Agreement.

         f.   To the extent permitted by law, no interest in this Agreement or
              benefits payable to you or to your Surviving Spouse shall be
              subject to anticipation, or to pledge, assignment, sale or
              transfer in any manner nor shall you or your Surviving Spouse have
              the power in any manner to charge or encumber such interest or
              benefits, nor shall such interest or benefits be liable or subject
              in any manner for the liabilities of you or your Surviving
              Spouse's debts, contracts, torts or other engagements of any kind.

         g.   No person other than you and your Surviving Spouse shall have any
              rights or property interest of any kind whatsoever pursuant to
              this Agreement, and neither you nor your

                                      -5-
<PAGE>   6

              Surviving Spouse shall have any rights hereunder other than those
              expressly provided in this Agreement. Upon the death of you and
              your Surviving Spouse no further benefits of whatsoever kind or
              nature shall accrue or be payable pursuant to this Agreement.

         h.   All benefits payable pursuant to this Agreement shall be paid in
              installments of one-twelfth of the annual benefit, or at such
              shorter intervals as may be deemed advisable by the Company in its
              discretion, upon receipt of your or your Surviving Spouse's
              written application, or by the applicant's personal representative
              in the event of disability.

         i.   All benefits under this Agreement shall be payable from the
              Company's general assets, which assets are subject to the claims
              of general creditors, and are not set aside for your or your
              Surviving Spouse's benefit.

         j.   This Agreement shall be governed by the laws of the State of
              Michigan.

     11. We have agreed that the determinations of the committee described in
paragraph 10a shall be conclusive as provided in such paragraph, but if for any
reason a claim is asserted which subverts the provisions of paragraph 10a, we
agree that, except for causes of action which may arise under paragraph 10b and
the first paragraph of paragraph 10c, arbitration shall be the sole and
exclusive remedy to resolve all disputes, claims or controversies which could be
the subject of litigation (hereafter referred to as "dispute") involving or
arising out of this Agreement. It is our mutual intention that the arbitration
award will be final and binding and that a judgment on the award may be entered
in any court of competent jurisdiction and enforcement may be had according to
its terms.

     The arbitrator shall be chosen in accordance with the commercial
arbitration rules of the American Arbitration Association and the expenses of
the arbitration shall be borne equally by the parties to the dispute. The place
of the arbitration shall be the principal offices of the American Arbitration
Association in the metropolitan Detroit area.

     The arbitrator's sole authority shall be to apply the clauses of this
Agreement.

     We agree that the provisions of this paragraph 11, and the decision of the
arbitrator with respect to any dispute, with only the exception provided in this
paragraph 11, shall be the sole and exclusive remedy for any alleged cause of
action in any manner based upon or arising out of this Agreement. Subject to the
foregoing exception, we acknowledge that since arbitration is the exclusive
remedy, neither of us or any party claiming under this Agreement has the right
to resort to any federal, state or local court or administrative agency
concerning any matters dealt with by this Agreement and that the decision of the
arbitrator shall be a complete defense to any action or proceeding instituted in
any tribunal or agency with respect to any dispute. The arbitration provisions
contained in this paragraph shall survive the termination or expiration of this
Agreement, and shall be binding on our respective successors, personal
representatives and any other party asserting a claim based upon this Agreement.

                                      -6-
<PAGE>   7

     We further agree that any demand for arbitration must be made within one
year of the time any claim accrues which you or any person claiming hereunder
may have against the Company; unless demand is made within such period it is
forever barred.

     We are pleased to be able to make this supplemental plan available to you.
Please examine the terms of this Agreement carefully and at your earliest
convenience indicate your assent to all of its terms and conditions by signing
and dating where provided below and returning a signed copy to me.

                                            Sincerely,

                                            MASCOTECH, INC.
