                                   GUIDELINES

1.       GUIDELINES
         ----------

         These 1997 Supplemental Annual Incentive Compensation Plan Guidelines
("Guidelines") have been approved by the Committee for the administration of the
NACCO Industries, Inc. Supplemental Annual Incentive Compensation Plan (the
"Plan") for Awards granted to Participants for the Award Term.

2.       DEFINITIONS
         -----------

         (a) "Adjusted ROE" means the Company's adjusted return on equity,
calculated as follows:

       Net Income (before extraordinary items) + Amortization of Goodwill
- --------------------------------------------------------------------------------
      Weighted Average (Stockholders' Equity + Accumulated Amortization of
                       Goodwill + UMWA Adjustment) where:

              (i) NET INCOME (BEFORE EXTRAORDINARY ITEMS) is defined as
consolidated net income for the Company and its subsidiaries for the Award Term
before extraordinary items, but including any extraordinary items related to
refinancing (net of tax), as such terms are defined by general accepted
accounting principles ("GAAP").

              (ii) AMORTIZATION OF GOODWILL is defined as the consolidated
amortization expense related to the intangible asset goodwill for the Company
and its subsidiaries for the Award Term.

              (iii) WEIGHTED AVERAGE STOCKHOLDERS' EQUITY is calculated by
adding the consolidated stockholders' equity for the Company, as defined by
GAAP, at the beginning of the Award Term and the end of each month of the Award
Term, and dividing by thirteen.

              (iv) WEIGHTED AVERAGE ACCUMULATED AMORTIZATION OF GOODWILL is
calculated by adding consolidated accumulated amortization of goodwill, as
defined by GAAP, at the beginning of the Award Term and the end of each month of
the Award Term, and dividing by thirteen.
 


   2
 
              (v) WEIGHTED AVERAGE UMWA ADJUSTMENT is calculated by adding the
balance in the Obligation to United Mine Workers of America Combined Benefit
Fund, net of tax, for the Company at the beginning of the Award Term and the end
of each month of the Award Term, and dividing by thirteen.

         (b) "Award" means cash paid to a Participant under the Plan for the
Award Term. The amount of an Award shall be not greater than a Participant's
Base Amount, multiplied by the ROE Factor.

         (c) "Award Term" means the period from January 1, 1997 through December
31, 1997.

         (d) "Base Amount" means for any Participant a dollar amount, which
shall be equal to the salary midpoint for the Salary Points assigned to the
Participant by the Committee for the Award Term multiplied by 40% of the
short-term incentive compensation target percent for those Salary Points.
Attached hereto as EXHIBIT A is a schedule listing the Base Amount for each
Participant for the Award Term.

         (e) "Committee" means the Committee appointed under the terms of the
Plan.

         (f) "Participant" means any salaried employee of the Company who in the
judgment of the Committee occupies a key position in which his efforts may
significantly contribute to the profits or growth of the Company. Directors of
the Company who are also employees of the Company are eligible to participate in
the Plan. Employees of the Company's subsidiaries shall not be eligible to
participate in the Plan. A Participant must be both employed by the Company and
a Participant on December 31 of the Award Term, and the amount of any Award to a
Participant who was not also employed by the Company and a Participant on the
first day of the Award Term shall be not more than the pro-rated amount based
upon the number of days actually employed by the Company in the Award Term.
Attached hereto as EXHIBIT A is a schedule listing the Participants for the
Award Term.

         (g) "ROE Factor" means a percentage based on Adjusted ROE for the Award
Term. Attached hereto as EXHIBIT B is a formula calculating the ROE Factor based
on Adjusted ROE for the Award Term.

         (h) "Salary Points" means the salary points assigned to a Participant
by the Committee pursuant to the Hay salary point system, or any successor
salary point system adopted by the Committee.

         ------

         3.1 AWARDS
             ------
 
         (a) PARTICIPANTS. EXHIBIT A lists the Participants and the Salary
Points, the salary midpoint, the short-term incentive compensation percent and
the Base Amount for each Participant for the Award Term. The Committee shall
have the power to add Participants at any later date in the Award Term if
individuals subsequently become eligible to participate in the Plan. Each
Participant shall be notified that he is eligible to receive an Award for such
term and the amount of his Base Amount. If a Participant, other than a
Participant who is, or is determined by the Committee to be likely to become, a
"covered employee" as defined in Section 162(m) of the Internal Revenue Code of
1986, as amended, receives a change in Salary Points, salary midpoint and/or
short-term incentive compensation target percent, such change and any resulting
change in his Base Amount will be reflected on an amended EXHIBIT A.
 

         (b) Not later than the ninetieth day of the following calendar year,
the Committee shall approve:

              (i) the ROE Factor for the Award Term and a preliminary
calculation of the amount of each Award based upon the application of the ROE
Factor to the Base Amount; and

              (ii) a final calculation of the amount of each Award to be paid to
each Participant for the prior year, which amount shall be not greater than the
amount determined in accordance with Section 3(b)(i). The Committee shall have
the power to decrease, but not to increase, the amount of any Award below the
amount determined in accordance with Section 3(b)(i).

         (c) Promptly following the approval of Awards for the Participants
pursuant to Section 3(b)(ii), the Company shall pay the amount of such Awards to
the Participants in cash, subject to all withholdings and deductions pursuant to
Section 4; provided, however, that no Award shall be payable to a Participant
except as determined by the Committee.

         (d) No Award may be paid for any year to a Participant in excess of
$800,000.

4.       WITHHOLDING TAXES

5.       AMENDMENT

         The Committee may alter or amend these Guidelines from time to time;
provided, however, that no such action shall, without the consent of a
Participant, affect the rights in an outstanding Award of such Participant; and
further provided, however, that no amendment to these Guidelines may be made
which would cause any amount paid to a Participant who is, or is determined to
be likely to become, a "covered employee" to be includable as "applicable
employee remuneration" of such Participant, as such terms are defined in Section
162(m) of the Internal Revenue Code of 1986, as amended.
