         SENIOR EXECUTIVE OFFICER NON-QUALIFIED STOCK OPTION AGREEMENT
                    PURSUANT TO THE MEDUSA CORPORATION 1991
                            LONG-TERM INCENTIVE PLAN


         THIS AGREEMENT, made and entered into as of this 8th day of May, 1995,
by and between Medusa Corporation, an Ohio corporation having its principal
executive offices at Monticello & Lee Boulevards, Cleveland Heights, Ohio 44118
(the "Company"), and [Fill-in: Participant] (the "Participant"),

                             W I T N E S S E T H :

         WHEREAS, the Participant is employed by the Company or by a Subsidiary
thereof, and pursuant to Article VI of the Medusa Corporation 1991 Long-Term
Incentive Plan (the "Plan"), the Company desires to award the Participant
certain Non-Qualified Stock Options pursuant to the Plan (the "Award").

         NOW THEREFORE, in consideration of the premises and other good and
valuable consideration each to the other in hand paid, the receipt and adequacy
whereof is hereby mutually acknowledged, the Company and the Participant hereby
mutually covenant and agree as follows:

1.       GRANT OF NON-QUALIFIED STOCK OPTIONS
                 The Company hereby grants to the Participant, and the
         Participant hereby accepts, [ Fill-in: Stock Options] Options to
         purchase Common Shares of Medusa Corporation (the "Company Common
         Shares") under the Plan.  The purchase price for each Company Common
         Share shall be $24.375, which is the Fair Market Value of a Company
         Common Share on May 8, 1995, the Date of Grant.  (The "Fair Market
         Value", as defined in the Plan, is the average of the high and low     
         quoted sales prices of a Company Common Share, as reported on the
         composite tape for the New York Stock Exchange.)

2.       TIMING OF EXERCISE
                 Each Option granted hereunder shall be exercised in whole or
         in part (in lots of ten shares or any multiple thereof) from
         time-to-time beginning from the Date of Grant, subject to the
         following time limitations:

         a.)     VESTING
                           Except in the event of a Change in Control, Options
                 may not be exercised in excess of (i) 50% of the total number
                 of Company Common Shares awarded to the Participant during the
                 second year after the Date of Grant; (ii) 75% during the third
                 year; and (iii) 100% thereafter.  In the event of a "Change of
                 Control", (as defined in the Plan) all Options shall become
                 immediately and fully exercisable.


                                     -1-
   2
         b.)     RIGHTS UPON TERMINATION, PRIOR TO VESTING
                           Options shall immediately expire if unvested as of
                 the date of Termination of Employment, except where the
                 Participant is a Senior Executive.

         c.)     RIGHTS UPON TERMINATION, AFTER VESTING

                 (i)       DEATH, DISABILITY, OR RETIREMENT
                                   In the event that the Participant terminates
                           his or her employment with the Company by reasons of
                           death, disability, or retirement, then the
                           Participant (or the Participant's Beneficiary, in
                           the case of death) shall have five (5) years from
                           the date of such event to exercise Options, or until
                           the expiration of the Options, whichever occurs
                           earlier.  (Reference should be made to the Plan
                           document for the additional information with respect
                           to the meaning of the terms "Termination of
                           Employment", disability, "Normal Retirement Date"
                           and "Other Retirement Date".)

                 (ii)      SENIOR EXECUTIVES
                                   For purpose of this Agreement, the term
                           "Senior Executive" shall mean the Chairman or the
                           President of the Company.  By Board action on May 8,
                           1995, Normal Retirement Date for a Senior Executive
                           may be any age (it is not limited to retirement at
                           age at 65 or thereafter).

                 (iii)     TERMINATION FOR REASONS OTHER THAN THE ABOVE
                                   Options shall expire if unexercised three
                           months after the date of Termination of Employment
                           for reasons other than those described in Subsection
                           (i), above.

         d.)     EXPIRATION
                        Options shall expire if not exercised within ten years 
                 from the Date of Grant.

3.       EXERCISE PROCEDURE
                 Each option shall be exercised by giving written notice to the
         Secretary of the Company on the Date of Exercise.  The Purchase Price
         of shares purchased upon exercise of an Option granted hereunder shall
         be paid by the Participant in full in cash, Company Common Shares, any
         combination of cash and Company Common Shares, or in accordance with a
         cash-less exercise program, under which, if so instructed by the
         Participant, Company Common Shares may be issued directly to the
         Participant's broker or dealer upon receipt of the Purchase Price in
         cash from the broker or dealer ("Cash-Less Exercise").  In the event
         that any Company Common Shares shall be transferred to the Company to
         satisfy all or any part of the Purchase Price, the part of the
         Purchase Price deemed to have been satisfied by such transfer of
         Company Common Shares shall be equal to the product derived by
         multiplying the fair market value (as defined in the Plan) as of the
         date of exercise times the number of Company Common Shares transferred
         to the Company. The Participant may not transfer to the Company in
         satisfaction of the Purchase Price any fraction of a Company Common
         Share.  As used





                                     -2-
   3
         above in this paragraph, the term "Company Common Shares" is defined
         as those shares which have been held by the Participant for six months
         or longer.

4.       ASSIGNABILITY
                 Other than for the purpose of a Cash-Less Exercise, as
         provided above, the Participant's rights and interest under this
         Agreement may not be assigned or transferred other than by will or the
         laws of descent and distribution, and during the lifetime of a
         Participant, only the Participant personally (or the Participant's
         Beneficiary) may exercise rights under this Agreement.  The
         Participant's Beneficiary may exercise the Participant's rights to the
         extent they are exercisable under the Plan following the death of the
         Participant.

5.       DILUTION AND OTHER ADJUSTMENTS

         a.)     RECAPITALIZATION
                           The number of shares awarded hereunder, the Purchase
                 Price or the Exercise Price for such shares, shall be
                 appropriately adjusted to reflect any stock dividend, stock
                 split, combination or exchange of shares, merger,
                 consolidation or other change in capitalization with a similar
                 substantive effect upon this Award.  The Organization and
                 Compensation Committee of the Board of Directors (hereinafter
                 called the "Committee") shall have the power and sole
                 discretion to determine the amount of the adjustment to be
                 made in each case.

         b.)     MERGER
                           After any Merger in which the Company is the
                 surviving corporation, the Participant shall, at no additional
                 cost, be entitled upon any exercise of an Option to receive
                 (subject to any required action by shareholders), in lieu of
                 the number of Company Common Shares receivable or exercisable
                 pursuant to this Award, the number of shares or other
                 securities to which the Participant would have been entitled
                 pursuant to the terms of the Merger if, at the time of the
                 Merger, the Participant had been the holder of record of a
                 number of shares equal to the number of shares receivable or
                 exercisable pursuant to this Award.  Comparable rights shall
                 accrue to the Participant in the event of successive Mergers
                 of the character described above.

6.       TAXES

         a.)               With respect to a Participant who is subject to the
                 provisions of Section 16(b) of the Exchange Act on the date on
                 which the withholding requirements apply, the Company shall
                 withhold from the Award the appropriate number of Company
                 Common Shares, rounded up to the next whole share, whose Fair
                 Market Value is equal to such amount, or, in the case of a
                 cash payment, the amount of cash, as is determined by the
                 Company to be sufficient to satisfy applicable tax withholding
                 requirements.





                                     -3-
   4
         b.)               With respect to a Participant who is not subject to
                 the provisions of Section 16(b) of the Exchange Act on the
                 date on which the withholding requirements apply, the
                 Participant shall have the right to elect to meet his or her
                 withholding requirement through the method described in
                 Subsection (a) above or by direct payment to the Company of
                 the amount of any taxes required to be withheld with respect
                 to the Award.

7.       MISCELLANEOUS PROVISIONS

         a.)     RIGHTS AS A SHAREHOLDER
                           The Participant or a transferee of any Options under
                 this Agreement shall have no rights as a shareholder with
                 respect to Company Common Shares covered by an Option until
                 the Participant or transferee shall have become the holder of
                 record of any such shares, and no adjustment shall be made for
                 dividends in cash or other property or distributions or other
                 rights with respect to any such Company Common Shares for
                 which the record date is prior to the date on which the
                 Participant or a transferee of the Option shall have become
                 the holder of record of any such shares covered by the Option;
                 provided, however, that Participants are entitled to share
                 adjustments to reflect capital changes under Section 5.

         b.)     PLAN PROVISIONS CONTROL AWARD TERMS
                           The terms of the Plan shall govern this Award.  In
                 the event any provision of this Award conflicts with any term
                 in the Plan as constituted on the Date of Grant of this Award,
                 the term in the Plan as constituted on the Date of Grant of
                 this Award shall control.  Except as provided in Subsection
                 (c) below, the terms of this Award may not be changed after
                 the Date of Grant of this Award so as to materially decrease
                 the value of this Award without the express written approval
                 of the Participant or transferee.

         c.)     MODIFICATION OF AWARD AFTER GRANT

                           This Award may not be modified (unless such
                 modification does not materially decrease the value of this
                 Award) after the Date of Grant except by express written
                 agreement between the Company and the Participant, provided
                 that any such modification (a) shall not be inconsistent with
                 the terms of the Plan, and (b) shall be approved by the
                 Committee.  No modification may be made to this Award while
                 the Participant is subject to Section 16(b) of the Exchange
                 Act except in compliance with Rule 16b-3.

         d.)     SURRENDER OF AWARDS
                           This Award may be surrendered to the Company for
                 cancellation on such terms as the Committee and the
                 Participant approve.

         e.)     NO RIGHT TO EMPLOYMENT
                           By this Award, neither the Participant or any other
                 person shall have any claim of right to be granted any
                 additional Awards under the Plan.  Neither the





                                     -4-
   5
                 Plan, this Award, nor any other action taken under the Plan
                 shall be construed as giving the Participant any right to be
                 retained in the employ of the Company or any of its
                 Subsidiaries.

         f.)     AWARDS NOT INCLUDABLE FOR BENEFIT PURPOSES
                           Any payments received by the Participant pursuant to
                 the provisions of this Award shall not be included in the
                 determination of benefits under any pension, group insurance
                 or other benefit plan applicable to the Participant which are
                 maintained by the Company or any of its Subsidiaries, except
                 as may be provided under the terms of such plans.

         g.)     NO STRICT CONSTRUCTION
                           No rule of strict construction shall be implied
                 against the Company, the Committee, or any other person in the
                 interpretation of this Award.

         h.)     COMPLIANCE WITH RULE 16B-3
                           It is intended that this Award shall be administered
                 in compliance with Rule 16b-3.  If any provision of this Award
                 would be in violation of Rule 16b-3 if applied as written,
                 such provision shall not have effect as written and shall be
                 given effect so as to comply with rule 16b3.  The Board of
                 Directors of the Company is authorized to make any such
                 modifications to this Agreement as are required to comply with
                 Rule 16b-3, as such rule may be amended from time to time.

         i.)     CAPTIONS
                           The captions (i.e., all Section headings) used in
                 this Agreement are for convenience only, do not constitute a
                 part of the Agreement, and shall not be deemed to limit,
                 characterize or affect in any way any provisions of the
                 Agreement, and all provisions of this Agreement shall be
                 construed as if no captions have been used in the Agreement.

         j.)     SEVERABILITY
                           Whenever possible, this Award shall be interpreted
                 in such manner as to be effective and valid under applicable
                 law, but if any provision of this Award shall be held to be
                 prohibited by or invalid under applicable law, then (i) such
                 provision shall be deemed amended to accomplish the objectives
                 of the provision as originally written to the fullest extent
                 permitted by law and (ii) all other provisions of this Award
                 shall remain in full force and effect.

         k.)     AMENDMENT
                           No amendment of the Plan may, without the consent of
                 the Participant, adversely affect the right of the Participant
                 under this Award.

         l.)     PLAN TERMINATION
                           In the event that the Participant is vested in this
                 Award at the time of the termination of the Plan, then the
                 Participant may exercise his or her rights under





                                     -5-
   6
                 this Award at any time prior to the expiration date of this
                 Award to the same extent this Award would have been
                 exercisable had the Plan not terminated.

         m.)     NOTICES
                           Except as otherwise expressly set forth in this
                 Agreement, any notice required to be given to the Participant
                 shall be sent to the address of the Participant as the same
                 appears on the records of the Company, or at such other
                 address as the Participant may hereafter designate in writing
                 and all notices required to be given to the Company shall be
                 addressed to the Secretary of the Company at the address set
                 forth above.  Any such notice shall be deemed to be duly given
                 if and when enclosed in a properly sealed envelope or wrapper
