NONFUNDED DEFERRED COMPENSATION AND UNIT AWARD PLAN FOR
                    NON-EMPLOYEE DIRECTORS

     1.   Each director who is not an employee of Minerals Technologies Inc.
(the "Company") or of any of its subsidiaries may elect on or before the last
day of any calendar month to have payment of (a) all or a specified part of all
fees payable to such director for services as a director during the following
calendar month and thereafter and/or (b) all or a specified part of all
dividends and other distributions payable on stock held by such director under
the Minerals Technologies Inc. Restricted Stock Plan for Non-Employee Directors
(hereinafter such dividends and other distributions are collectively referred to
as "dividends")  deferred until such director ceases to be a director of the
Company.  Any such election shall be made by written notice directed to the
Secretary of the Company.  Any such election may be terminated, or may be
modified as to amount of deferral or form of deferral (whether dollars or
units), with regard to fees and/or dividends to be paid during the following
calendar month and thereafter upon written notice directed to the Secretary of
the Company on or before the last day of the calendar month preceding the
calendar month in which such fees and/or dividends would otherwise be payable.
Modifying the form of deferral of fees and/or dividends previously deferred may
be done as of the first day of any calendar month by giving written instructions
to the Secretary of the Company before such date.  No more than two
modifications of the form of deferral, whether as to fees and/or dividends
previously deferred or as to fees and/or dividends to be paid, may be made in
any calendar year.  The Awarded Units, as described in paragraph 2, shall not be
affected by any such election.

     2.   "An award consisting of 400 units shall be made to each director
upon joining the Board.  Each director who continues in office on the date of
any annual meeting of stockholders shall be awarded 400 units, effective as of
such date.  An award of 50 units per year in equal quarterly amounts shall be
made to each director who serves as a member of a committee of the Board.  In
addition, an award consisting of 15 units shall be made to each director upon
commencement of service as chair of a committee of the Board, and each director
who continues as chair of a committee on the date of any annual meeting of
stockholders shall be awarded 15 units, effective as of such date.  An award
consisting of 25 units shall be made to each director who serves as chair of a
meeting of a committee of the Board, and an award of 15 units shall be made to
each Board member, other than the chair, who attends a meeting of a committee of
the Board."

     3.   A general ledger account (the "Deferred Directors Fees Account") shall
be set up on the Company's books and shall reflect the market value of the fees
and/or dividends deferred by each director and of the Awarded Units awarded to
him/her pursuant to paragraph 2.  As  fees and/or dividends are deferred by each
director, they shall be credited to the Deferred Directors Fees Account.  At
the director's election, such credit shall be in the form of either  (a) the
dollar amount of the fees and/or dividends deferred or (b) a number of units,
calculated to the nearest thousandth of a unit, determined by dividing the
dollar amount of fees and/or dividends deferred by the closing market price of
the Company's Common Stock as reported on the Consolidated Tape of the New York
Stock Exchange on the last business day prior to the date such fees and/or
dividends would otherwise have been paid.  Dollar balances in a director's
account shall be credited with  interest at a rate equal to the rate of return
for Fund I in the Minerals Technologies Inc. Savings and Investment Plan,
compounded monthly. Units in a director's account, whether Awarded Units or 
deferred fee or dividend  units pursuant to clause (b) above, or dividends 
thereon, shall be marked to market monthly.  In the case of Awarded Units, 
the director's account shall be credited with the number of units
so awarded on the date specified in paragraph 2.  Whenever a dividend is
declared, the number of units in the director's account shall be increased by
the result of the following calculations: (i) the number of units in the
director's account multiplied by any cash dividend declared by the Company on a
share of its Common Stock, divided by the closing market price of such Common
Stock on the related dividend record date; and/or (ii) the number of units in
the director's account multiplied by any stock dividend declared by the Company
on a share of its Common Stock.  Solely as to the Awarded Units, a director may
elect to receive in cash the value of any cash dividend declared by the Company
on a share of its Common Stock in lieu of having his/her account credited as
specified above.  Any such election shall be made, and may also be terminated,
by written notice directed to the Secretary of the Company prior to the calendar
month of the payment date for the dividend.  In the event of any change in the
number or kind of outstanding shares of Common Stock of the Company including a
stock split or splits, other than a stock dividend as provided above, an
appropriate adjustment shall be made in the number of units credited to the
director's account.

     4.   At least  one year before a director ceases to be a director of the
Company, such director may elect, or may modify an election previously made, to
receive payment of his/her interest in the Deferred Directors Fees Account  in a
lump sum or in annual installments, and may elect  to have such payment or
payments  made either in (a) the year in which the electing director ceases to
be a director of the Company, or (b) the year following such director's
termination as a director. In the absence of an election, such payments will
begin with the first month of the year following the director's termination and
will be made in five annual installments.  In the event a director ceases to be
a director of the Company within one year of such director's most recent
exercise, or modification of, the election provided for herein, then any
previous election made by such director shall be deemed to remain in effect.

     With respect to all units in the Deferred Directors Fees Account, whether
they be Awarded Units credited pursuant to paragraph 2, units representing fees
calculated as provided in paragraph 3, or units representing dividends, the
amount payable to the director in each instance shall be determined by
multiplying the number of units by the closing market price of the Company's
Common Stock on the last business day prior to the date for payment.

     Where the director receives the balance of his/her account in Annual
Installments of Deferred Compensation, the first Annual Installment of Deferred
Compensation shall be a fraction of the value of the balance of the deferred 
compensation and Awarded Units credited to the director's account either by 
way of interest or units calculated under paragraph 3 hereof, as the case may 
be, on the date of such payment, the numerator of which is one (1) and the 
denominator of which is the total number of installments remaining to be 
paid at that time.  Each subsequent Annual Installment shall be calculated 
in the same manner except that the denominator shall be reduced by the 
number of Annual Installments which have been previously paid.

     5.   If a director should die before full payment of all amounts credited
to his/her account, such amounts shall be paid to his/her designated beneficiary
or beneficiaries or to his/her estate in a single sum payment to be made as soon
as practicable after his/her death.  A director may designate one or more
beneficiaries (which may be an entity other than a natural person) to receive
any payments to be made upon the director's death.  At any time, and from time
to time, any such designation may be changed or canceled by the director without
the consent of any beneficiary.  Any such designation, change or cancellation
must be by written notice filed with the Secretary of the Company and shall not
be effective until received by the Secretary.  If a director designates more
than one beneficiary, any payments to such beneficiaries shall be made in equal
shares unless the director has designated otherwise.  If no beneficiary has been
named by the director, or the designated beneficiaries have predeceased such
director, the beneficiary shall be the executor or administrator of the
director's estate.

     6.   A director's election to defer fees shall continue until a director
ceases to be a director unless such director earlier terminates such election
with respect to future fees by written notice delivered to the Secretary of the
Company.  Any such notice shall become effective as of the end of the calendar
month in which such notice is received by the Secretary.  Amounts credited to
the account of a director prior to the effective date of such notice shall not
be affected thereby and shall be paid to the director in accordance with
paragraph 4 (or paragraph 5 in the event of his death) above.  The Awarded Units
shall not be affected by any such election.

     7.   The right of a director to any fees or Awarded Units credited to
his/her account shall not be subject to assignment by such director.  If a
director does assign his right to any fees or Awarded Units credited to his/her
account, the Company may disregard such assignment and discharge its obligation
hereunder by making payment as though no such assignment had been made.

     8.   In no event shall any payment of fees deferred pursuant to the Plan or
of Awarded Units be made with the Company's Common stock.
