          WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.

                               MEDUSA CORPORATION

SUMMARY OF THE PLAN

         The Board of Directors of Medusa Corporation ("Medusa" or the
"Company") adopted a new incentive benefit plan on February 25, 1991, believing
that the continuation of a sound long-term incentive benefit program was in the
best interests of Medusa in its continuing efforts to attract and retain highly
competent employees and to act as an incentive in motivating selected officers
and other key employees of Medusa and its subsidiaries to achieve long-term
corporate objectives.  The 1991 Long-Term Incentive Plan of Medusa Corporation
("1991 Plan") was approved by the shareholders of Medusa at the Annual Meeting
of Shareholders held on May 6, 1991.  The 1991 Plan allows the Organization and
Compensation Committee of the Board of Directors (the "Committee") the
flexibility to award various types of long-term compensation incentives.  Such
grants may, but need not, be based upon criteria such as increased shareholder
value, earnings per share, return on investment, return on shareholders' equity
and other company and individual performance goals.

         The 1991 Plan may be amended, modified or terminated at any time by
action of the Board of Directors of the Company and, with the consent of the
participant, any outstanding agreement or award may be amended, modified or
terminated by action of the Committee.  Shareholder approval is required for
any modification which would (i)  increase the total number of Medusa
Corporation Common Shares, without par value (the "Common Shares"), with
respect to which options may be granted, (ii)  change the employees or class of
employees to whom options may be granted or (iii)  materially increase the
benefits accruing to participants under the 1991 Plan.  Notwithstanding the
foregoing, Common Shares that are reserved for issuance pursuant to the 1991
Plan are appropriately and proportionately adjusted to reflect any stock
dividend, stock split or other change in the Company's capitalization.  The
1991 Plan has no fixed expiration date.  The Committee is authorized to
establish expiration and exercise dates on an award-by-award basis.  However,
for the purpose of awarding Incentive Stock Options under Section 422A of the
Code, the 1991 Plan will expire on May 6, 2001, which is ten years from the
date of shareholder approval.  The 1991 Plan is not subject to any provisions
of the Employee Retirement Income Security Act of 1974.


PLAN ADMINISTRATION

         The 1991 Plan is administered by the Committee.  The members of the
Committee are appointed by the full Board of Directors of the Company for
one-year terms.  All Committee members are ineligible, and have been ineligible
for a period of at least one year prior to their appointment, to participate in
the 1991 Plan or any other restricted stock, stock option or stock appreciation
right plan of the Company or any of its affiliates.  The names of the members
of the Committee who presently administer the 1991 Plan are:

                               Dorsey R. Gardner
                               Jean Gaulin
                               Dwight C. Minton
                               Boris Yavitz, Chairman





                                      I-2
<PAGE>   4
         Each of the members and the Committee maintains an address for
correspondence with respect to Committee business at the offices of the
Company, at 3008 Monticello Boulevard, Cleveland Heights, Ohio 44118.

         Subject to the express terms of the 1991 Plan, the Committee has
conclusive authority to construe and interpret the 1991 Plan, any restricted
stock, stock option or stock appreciation right agreement entered into
thereunder, and to establish, amend and rescind rules and regulations for its
administration.  The Committee also has such additional authority with respect
to the 1991 Plan as the Board of Directors may from time-to-time determine to
be necessary or desirable.


PRINCIPAL FEATURES OF THE 1991 PLAN

         AMOUNT OF STOCK - The 1991 Plan currently provides for awards of up to
1,500,000 shares, subject to anti-dilution adjustments upon the occurrence of
significant corporate events.  The shares to be offered under the 1991 Plan
will be either authorized and unissued shares or issued shares which have been
reacquired by Medusa.

         ELIGIBILITY AND PARTICIPATION - All officers and Committee-designated
key employees of Medusa or any subsidiary are eligible to participate,
including officers who are also Directors of Medusa or its subsidiaries.  The
Committee may also grant awards to non-employees who, in the judgment of the
Committee, render significant service to Medusa or any of its subsidiaries.
With respect to future awards, at the time of the filing of this amendment, the
Committee has made no determination as to the particular officers and key
employees to whom long-term incentive benefits under the 1991 Plan will be
made, the type of incentive compensation under the 1991 Plan which will be
awarded or the number of share benefits which will be awarded to any person.


RESTRICTED SHARE COMPONENT OF THE 1991 PLAN

         The Committee may award to a participant Common Shares subject to
specified restrictions ("Restricted Shares").  Restricted Shares are subject to
forfeiture if the participant does not meet certain conditions such as
continued employment over a specified forfeiture period (the "Forfeiture
Period") and/or the attainment of specified performance targets over the
Forfeiture Period.  The terms and conditions of Restricted Share awards are
determined by the Committee, provided that, unless otherwise determined by the
Board, the specified Forfeiture Period may not be less than one year.

         Participants who have been awarded Restricted Shares will have all of
the rights of a holder of outstanding Common Shares, including the right to
vote such shares and to receive dividends.  During the Forfeiture Period,
Restricted Shares are nontransferable and may be held in custody by Medusa or
its designated agent, or if the certificate is properly legended, by the
participant.  Upon the lapse or release of all restrictions, an unrestricted
certificate will be provided to the participant.

         The Committee, at its sole discretion, may waive all restrictions with
respect to a Restricted Share award under certain circumstances (including the
death, disability, or retirement of a participant, or a material change in
circumstances arising after the date of grant) subject to such terms and
conditions as it deems appropriate.  However, only the Board may waive
restrictions within one year of the date of grant.





                                      I-3
<PAGE>   5
STOCK OPTION COMPONENT OF THE 1991 PLAN

         The Committee may grant to a participant non-qualified stock options,
Incentive Stock Options or a combination thereof.  The terms and conditions of
stock option grants including the quantity, price, waiting periods, and other
conditions on exercise will be determined by the Committee.  Incentive Stock
Option grants are made in accordance with Section 422A of the Code.

         The exercise price for stock options will be determined by the
Committee at its discretion, provided that the exercise price for each
Incentive Stock Option is at least equal to 100% of the fair market value of a
Common Share on the date when the stock option is granted.  Unless otherwise
authorized by the Board, generally no stock option may be exercised prior to
six months from the date of grant.

         Upon a participant's termination of employment for any reason, any
stock options which were not exercisable on the participant's termination date
will expire.  In the case of a participant who retires from Medusa and
continues to render significant services to Medusa after retirement, the
Committee, at its discretion, may permit the period during which the
participant continues to render such services to Medusa to count toward the
participant's vesting requirement with respect to stock options that were not
exercisable at the time of the participant's termination of employment.

         Except with respect to stock option awards made by the Committee after
May 9, 1994 to the Chairman and President ("Senior Executive Officers"; whose
awards continue to survive on a post-employment basis for the balance of the
exercise period), upon a participant's termination of employment for reasons
other than death, disability or normal retirement, stock options which were
exercisable on the participant's termination date will expire three months from
the date of termination, unless the right to exercise the options is extended
by the Committee at its discretion.  In general, upon a participant's
termination by reason of death, disability or normal retirement, stock options
which were exercisable on the participant's termination date may continue to be
exercised by the participant (or the participant's beneficiary) for a period of
five years from the date of the participant's termination of employment.

         Subject to the Committee's discretion, payment for Common Shares on
the exercise of stock options may be made in cash, Common Shares, a combination
of cash and Common Shares or in any other form of consideration acceptable to
the Committee (including one or more "cashless" exercise forms).  The Committee
has the discretion to cause Medusa to assist a participant in exercising stock
options by lending sufficient cash to the participant or by guaranteeing a
participant's bank loan.  In such event, Medusa would hold the shares acquired
upon exercise of the option as security for repayment of the loan.  On March
27, 1995, the Board of Directors approved a non-substantive amendment to the
1991 Plan, authorizing an annual limitation of 100,000 in the issuance of stock
options to a participant, thereby qualifying such awards as "performance-based
compensation" under Section 162(m) of the Code.


STOCK APPRECIATION RIGHT COMPONENT OF THE 1991 PLAN

         Stock Appreciation Rights ("SARs") may be granted by the Committee to
a participant either separate from or in tandem with non-qualified stock
options or Incentive Stock Options.  SARs may be granted at the time of the
stock option grant or, with respect to non-qualified stock options, at anytime
prior to the exercise of the stock option.  An SAR entitles the participant to
receive, upon its exercise, a payment equal to (i)  the difference between the
SAR exercise price and the fair market value of a Common Share on the exercise
date, times (ii)  the number of Common Shares with respect to which the SAR is
exercised.  Upon exercise of an





                                      I-4
<PAGE>   6
SAR with respect to Common Shares, the number of Common Shares covered by the
SARs related stock option, if any, are correspondingly reduced.

         SARs granted in tandem with options are generally governed by the same
terms and conditions as govern the related stock option and may only be
exercised to the extent the related stock option is exercisable.  However, SARs
which are granted in tandem with previously granted non-qualified stock options
cannot be exercised prior to six months from the date of the SAR grant.

         The exercise price of an SAR is determined by the Committee, but in
the case of SARs granted in tandem with stock options, may not be less than the
exercise price of the related stock option.  Upon exercise of an SAR, payment
will be made in cash or Common Shares, or a combination thereof, as determined
at the discretion of the Committee.  On March 27, 1995, the Board of Directors
approved a non-substantive amendment to the 1991 Plan, authorizing an annual
limitation of 100,000 in the issuance of SARs to a participant, thereby
qualifying such awards as "performance-based compensation" under Section 162(m)
of the Code.  (Note: Through December 31, 1995, the Committee has not awarded
any SARs under the 1991 Plan.)


PERFORMANCE AWARD COMPONENT OF THE 1991 PLAN

         The Committee may grant performance awards to participants under such
terms and conditions as the Committee deems appropriate.  A performance award
entitles a participant to receive a payment from Medusa, the amount of which is
based upon the attainment of predetermined performance targets over a specified
award period.  Performance awards may be made in conjunction with Restricted
Share awards.  Performance awards may be paid in cash, Common Shares or a
combination thereof, as determined by the Committee.

         Award periods will be established at the discretion of the Committee.
The performance targets will also be determined by the Committee and may, but
need not include specified levels of earnings per share, return on investment,
return on shareholders' equity and/or such other goals related to the Company's
or the individual's performance as are deemed appropriate by the Committee.
When circumstances occur which cause predetermined performance targets to be an
inappropriate measure of achievement, the Committee, at its discretion, may
adjust the performance targets.

         If the minimum performance targets established by the Committee are
not met, no payment will be made to the participant.  If the performance
targets are fully achieved, 100% of the performance award will be paid to the
participant.  The Committee may also provide for payment of up to 150% of a
performance award for achievement which exceeds the performance targets.

         If a participant terminates employment prior to the end of an award
period, the participant generally will forfeit all rights to any performance
award, unless otherwise provided by the Committee.  The Committee, at its
discretion, may determine to pay all or any portion of a performance award to a
participant who has terminated employment prior to the end of an award period
under certain circumstances (including death, disability, retirement or a
material change in circumstances arising after the date of grant), provided
that the participant completed at least one year of employment following the
grant of the award.  The Board may determine to pay all or a portion of a
performance award to a participant who has terminated employment less than one
year following the date of grant.





                                      I-5

OTHER AWARDS

         The Committee is authorized to grant any other cash awards, Common
Share awards or other types of awards which are valued in whole or in part by
reference to the value of Common Shares.  The terms and conditions of such
awards and the participants eligible for such awards will be determined by the
Committee at its discretion.


SHARES SUBJECT TO THE 1991 PLAN

         Effective May 9, 1994, up to 1,500,000 Common Shares in the aggregate
became available for issuance by the Committee under the 1991 Plan, subject to
further adjustment for any change in the Common Shares (including any change
which would result in a substantial dilution or enlargement of the rights or
economic benefit inuring to holders of shares or options issued under the 1991
Plan.  Shares or options which, from time-to-time, are awarded by the Committee
under the 1991 Plan will be made available either from authorized and unissued
Common Shares or from reacquired Common Shares, including shares purchased in
the open market.  If any Common Shares awarded under the 1991 Plan are
reacquired by the Company pursuant to the forfeiture provisions of the 1991
Plan, such shares shall again become available for use under the 1991 Plan and
shall be regarded as not having been previously awarded.


AWARDS UNDER THE 1991 PLAN

         With respect to the fiscal years 1991, 1992, 1993, 1994 and 1995, the
Committee awarded under the 1991 Plan, 82,500, 82,500, 112,500, 79,950 and
112,820 Restricted Shares, respectively, and 130,125, 153,750, 174,750, 246,000
and 247,000 stock options, respectively, all at fair market value on the date
of award, under award terms listed in detail as follows:

         A)      RESTRICTED STOCK AWARDED FROM 1991 THROUGH 1995

                 PERFORMANCE RESTRICTED SHARES AWARDED IN 1991 AND 1992 - In
         respect to the fiscal 1991 and fiscal 1992 awards, and pursuant to the
         Performance Restricted Share Agreements between the Company and the
         participants, 50% of each share award is restricted until a test date
         2 1/2 years from the date of the award and 50% of the award is
         restricted until a test date 5 years from the date of the award.  In
         order for the shares restriction to lapse, the Growth Rate of the
         Common Shares on a test date must meet or exceed, cumulatively, 15%
         per annum over the award price. (The term "Growth Rate," includes
         market value appreciation, distributions and dividends.)   If the
         restrictions on the initial 50% of the share award fail to lapse on
         the 2 1/2-year test date, then such portion is not forfeit until it is
         retested on the 5-year test date.  By agreement, upon the lapse of
         restrictions, the Company will provide additional compensation ("Gross
         up") in an amount sufficient to pay the recipient's tax liability on
         the Performance Restricted Shares.

                 PERFORMANCE RESTRICTED SHARES AWARDED IN 1993 AND 1994 - In
         respect to the fiscal 1993 and fiscal 1994 awards, and pursuant to the
         Performance Restricted Share Agreements between the Company and the
         participants, 50% of each share award is restricted until a test date
         2 1/2 years from the date of the award and 50% of the award is
         restricted until a test date 5 years from the date of the award.  In
         order for the share restrictions to lapse, two requirements must be
         met:  a) the value of a Common Share (adjusted for stock distribution,
         but not reflecting dividends) may not decline from the date of the
         award to a test date; and b) the Common Share Growth Rate must meet or
         exceed 125% of the Growth Rate of the Standard and Poor's 500
         Composite, when measured from the date of the award





                                      I-6
<PAGE>   8
         to a test date.  If the restrictions on the initial 50% of the share
         award fail to lapse on the 2 1/2 year test date, then such portion is
         not forfeit until it is retested on the 5-year test date.  By
         agreement, upon the lapse of restrictions, the Company will Gross-up
         participants' compensation.  On May 9, 1994, the shareholders approved
         the material terms of performance goals contained in the fiscal 1993
         and 1994 Performance Restricted Share awards, thereby qualifying such
         awards as "performance-based compensation" under Section 162(m) of the
         Code.

                 RESTRICTED SHARES AWARDED IN 1995 - In respect to the fiscal
         1995 awards, and pursuant to the Restricted Share Agreements between
         the Company and the participants, the number of Restricted Shares
         awarded (restricted for a period of up to 5 years) is divided into two
         portions, as follows:  a) a Supplemental Executive Retirement Plan
         ("SERP")-Equivalent portion, consisting of time-based Restricted
         Shares (with the number awarded to be determined by the Company's
         actuary, based upon the terms and conditions of the Company's
         SERP-Equivalent Plan), and b) a Performance Restricted Share portion,
         the balance of the award, which consists of performance-based shares.
         A one-fifth portion of the Performance Restricted Share award is
         thereafter tested in each year during the restriction period.  In
         order for the share restrictions to lapse, two requirements must be
         met:  (i) the value of a Common Share (adjusted for stock
         distributions, but not reflecting dividends) may not decline from the
         date of the award to a test date; and (ii) the Common Share Growth
         Rate must meet or exceed 110% of the Growth Rate of a "Cement Industry
         Peer Group," when measured from the date of the award to a test date.
         There is also a provision for "Partial Lapses" with respect to
         proportionate amounts of the shares in 10% increments if more than
         101%, but less than 110% of the performance objective is attained.
         (i.e., a 101% Growth Rate causes the restrictions to lapse with
         respect to 10% of the shares, etc.).  If the restrictions on all or
         part of any one-fifth portion of the share award fails to lapse, then
         such portion or portions are not forfeit until they are retested, as
         applicable, during the 5-year restriction period.  By agreement, upon
         the lapse of restrictions on Performance Restricted Shares, the
         Company will Gross-up participants' compensation.

                 AIP RESTRICTED SHARES AWARDED IN 1994 AND 1995 - In fiscal
         1994 and fiscal 1995, the Committee authorized the executive officers
         of the Company to elect to take their 1993 and 1994 Annual Incentive
         Plan awards, respectively, in time-based Restricted Shares instead of
         cash, with a 2-year share restriction period, an election under
         Section 83(b) of the Code and a Gross-up.

                 GENERAL - The recipient of an award of Restricted Shares will
         not, with respect to such award, be deemed to have become a
         participant or to have any rights with respect to such award, unless
         and until such recipient executes an agreement or other instrument
         evidencing the award and delivers a fully executed copy thereof to the
         Company and otherwise complies with the then applicable terms and
         conditions of such award.

                 Each participant will be issued a certificate in respect of
         Restricted Shares awarded under the 1991 Plan.  Such certificate will
         be registered in the name of the participant, and will bear an
         appropriate legend referring to the terms, conditions and restrictions
         applicable to such award substantially in the following form:





                                      I-7
<PAGE>   9
                          "The transferability of this certificate and the
                 Common Shares represented hereby are subject to the terms and
                 conditions (including forfeiture) of the Medusa Corporation
                 1991 Long-Term Incentive Plan and an Agreement entered into
                 between the registered owner and Medusa Corporation.  Copies
                 of such Plan and Agreement are on file in the offices of the
                 Secretary, Medusa Corporation, 3008 Monticello Boulevard,
                 Cleveland Heights, Ohio 44118."

                 All certificates for Restricted Shares delivered under the
         Plan will be subject to such stop-transfer orders and other
         restrictions as the Committee may deem advisable under the rules,
         regulations, and other requirements of the Securities and Exchange
         Commission (the "Commission"), any stock exchange upon which the
         Common Shares are then listed and any applicable federal or state
         securities laws, and the Committee may cause a legend or legends to be
         placed on any such certificates to make appropriate reference to such
         restrictions.

                 The Committee may adopt rules which provide that the
         certificates evidencing such Restricted Shares may be held in custody
         by a bank or other institution, or that the Company may itself hold
         such Restricted Shares in custody, until the restrictions thereon have
         lapsed and may require, as a condition of any award, that the
         participant deliver a stock power endorsed in blank relating to the
         shares covered by such award.

                 Recipients of awards under the 1991 Plan are not required to
         make any payment or provide consideration other than the rendering of
         services to the Company in connection with the award of Restricted
         Shares under the 1991 Plan.

                 RESTRICTIONS - With respect to the up to 5-year restriction
         period for the SERP-Equivalent Restricted Shares and the Performance
         Restricted Shares and the 2-year restriction period for the AIP Award
         Restricted Shares described above commencing with the date of an award
         (the "Restriction Period"), a participant will not be permitted to
         sell, transfer, pledge or assign Restricted Shares awarded to him or
         her.  Any attempt to dispose of Restricted Shares in a manner contrary
         to such restrictions shall be ineffective.  However, no provisions of
         the 1991 Plan preclude a participant from exchanging any Restricted
         Shares for any other Common Shares that are similarly restricted.

                 FORFEITURE OF RESTRICTED SHARES - Except with respect to
         Restricted Shares awards made by the Committee after May 9, 1994 to
         Senior Executive Officers (whose awards continue to survive on a
         post-employment basis for the balance of the Restriction Period), upon
         termination of employment during the Restriction Period for any reason
         or upon the end of the Restriction Period, in either case prior to the
         lapse or termination of the relevant restrictions, all shares still
         subject to restriction will be forfeited by the participant and will
         be reacquired by the Company.  In the event of a participant's
         retirement, permanent total disability, or death, or in cases of
         special circumstances, in its sole discretion, when it finds that a
         waiver would be in the best interests of the Company, the Committee
         may waive in whole or in part any or all remaining restrictions with
         respect to such participant's Restricted Shares.

                 In the event of a change in control of the Company, any and
         all remaining restrictions with respect to a participant's Restricted
         Shares shall lapse.  For purposes of the 1991 Plan, the term "Change
         in Control" means any of the following events:

                          "(a)  The acquisition, other than from the Company,
                 by any individual, entity or group (within the meaning of
                 Section 13(d)(3) or 14(d)(2) of the Exchange Act) of
                 beneficial ownership (within the meaning of Rule 13d-3
                 promulgated under the Exchange Act) of 20% or more of either
                 (i)  the Outstanding Company Common Shares or (ii)  the
                 Company Voting Securities; provided, however, that the
                 following shall not constitute a Change in Control:  any
                 acquisition by (A)  the Company or any of its Subsidiaries, or
                 any employee benefit plan (or related trust) sponsored or
                 maintained by the Company or any of its Subsidiaries, or (B)
                 any corporation with respect to which, following such
                 acquisition, more than 60%, respectively, of the then
                 outstanding common shares of such corporation and the combined
                 voting power of the then outstanding voting securities of such
                 corporation entitled to vote generally in the election of
                 directors is then beneficially owned, directly or indirectly,
                 by all or substantially all of the individuals and entities
                 who were the beneficial owners, respectively, of the
                 Outstanding Company Common Shares and Company Voting
                 Securities immediately prior to such acquisition in
                 substantially the same proportion as their ownership,
                 immediately prior to such acquisition, of the Outstanding
                 Company Common Shares and Company Voting Securities, as the
                 case may be; or

                          (b)     Individuals who constitute the Incumbent
                 Board cease for any reason to constitute in excess of
                 two-thirds of the Board; provided, however, that any
                 individual becoming a director subsequent to February 25, 1991
                 whose election or nomination for election by the Company was
                 approved by a vote of at least a majority of the directors
                 then comprising the Incumbent Board shall be considered as
                 though such individual were a member of the Incumbent Board,
                 but excluding, for this purpose, any such individual whose
                 initial assumption of office is in connection with an actual
                 or threatened election contest relating to the election of
                 members of the Board; or

                          (c)     Approval by the shareholders of the Company
                 of a reorganization, merger or consolidation ("Merger"),
                 unless, all or substantially all of the individuals and
                 entities who were the respective beneficial owners of the
                 Outstanding Company Common Shares and Company Voting
                 Securities immediately prior to the Merger, following such
                 Merger do beneficially own, directly or indirectly, more than
                 60%, respectively, of the then outstanding common shares and
                 the combined voting power of the then outstanding voting
                 securities entitled to vote generally in the election of
                 directors, as the case may be, of the corporation which
                 results from the Merger, in substantially the same proportion
                 as their ownership of the Outstanding Company Common Shares
                 and Company Voting Securities, as the case may be, immediately
                 prior to the Merger.

                          (d)     Approval by the shareholders of the Company
                 of (i)  a complete liquidation or dissolution of the Company
                 or (ii)  a sale or other disposition of all or substantially
                 all of the assets of the Company other than to a corporation
                 with respect to which, following such sale or disposition,
                 more than 60%, respectively, of the then outstanding common
                 shares and the combined voting power of the then outstanding
                 voting securities entitled to vote generally in the election
                 of directors is then owned beneficially, directly or
                 indirectly, by all or substantially all of the individuals and
                 entities who were the beneficial owners, respectively, of the
                 Outstanding Company Common Shares and Company Voting
                 Securities immediately prior to such sale or disposition in
                 substantially the same proportion as their ownership of the
                 Outstanding Company Common Shares and Company Voting
                 Securities, as the case may be, immediately prior to such sale
                 or disposition."

                 In the event of a Change in Control, stock options and SARs
         immediately become exercisable, the restrictions on all Restricted
         Shares lapse and all performance awards immediately become payable.
         The 1991 Plan contains special provisions regarding the exercisability
         of stock options and SARs in the event of a Change in Control by
         individuals subject to Section 16(b) of the Exchange Act (certain
         officers and directors).

                 DIVIDENDS AND OTHER RIGHTS - With respect to the Restricted
         Shares, the participant shall have all of the rights of a shareholder
         of the Company, including the right to vote the Restricted Shares and
         receive cash dividends and other distributions with respect thereto;
         provided nonetheless, that share distributions shall be subject to the
         same restrictions as the Restricted Shares.

                 MISCELLANEOUS - No employee or other person will have any
         claim or right to be granted Restricted Shares under the 1991 Plan,
         and neither the 1991 Plan nor any action taken thereunder will be
         construed as giving any participant, recipient, employee or other
         person any right to be retained in the employ of the Company.  Income
         realized as a result of an award of Restricted Shares will not be
         included in the participant's earnings for the purpose of any benefit
         plan in which the participant may be enrolled or for which the
         participant may become eligible unless otherwise specifically
         authorized in such plan.

                 RESTRICTIONS ON RESALE OF COMMON SHARES - Under the Securities
         Act of 1933, as amended (the "Securities Act"), persons participating
         in the 1991 Plan who are deemed to be "Affiliates" of the Company are
         restricted in the resale of the Common Shares owned by them (whether
         such shares are acquired pursuant to the Plan or otherwise and even if
         the shares are not, or are no longer, subject to the contractual
         transferability restriction discussed above).  For this purpose, an
         "Affiliate" of the Company is any person who controls the Company, is
         controlled by the Company, or is under common control with the
         Company, whether directly or indirectly through one or more
         intermediaries.  A corporation's Affiliates would usually include all
         persons whose security holdings are substantial enough to affect its
         management.  Also, all directors and executive or policy-making
         officers are presumed to be Affiliates.  Resales by Affiliates may be
         made only pursuant to an effective registration statement under, or
         pursuant to an exemption from, the registration requirements of the
         Securities Act.  One such exemption is provided for certain "brokers'
         transactions" that comply with all the conditions set forth in Rule
         144 of the Commission.  No registration statement covering resales by
         Affiliates is currently anticipated to be filed.

         B)      STOCK OPTIONS AWARDED FROM 1991 THROUGH 1995

                 GENERAL - The terms and conditions of the stock options
         awarded under the 1991 Long-Term Incentive Plan are similar to the
         terms and conditions of the awards under the Medusa Corporation 1988
         Stock Option Plan.  The fiscal 1991 through fiscal 1994 awards of
         non-qualified stock options were granted for a period of five years
         and the fiscal 1995 stock option awards were granted for a period of
         ten years and are exercisable starting one year from date of grant at
         a cumulative rate of 50% of the total shares available during the
         second year, 75% during the third year and 100% thereafter.  The
         recipient of an award of stock options will not, with respect to such
         award, be deemed to have become a participant or to have any rights
         with respect to such award, unless and until such recipient executes
         an agreement or other instrument evidencing the award and delivers a
         fully executed copy thereof to the Company and otherwise complies with
         the then applicable terms and conditions.

<PAGE>   12
                 ELIGIBILITY AND PARTICIPATION - All key employees of the
         Company or any majority-owned subsidiary will be eligible to
         participate, including officers or employees who may also be directors
         of the Company or of any of its subsidiaries, but not including any
         employee who owns more than 10% of the shares of the Company or any
         such subsidiary.  The Committee, in its discretion upon the
         recommendation of management, will determine those employees who, as
         key employees, shall be granted stock options in such amounts as may
         be determined by the Committee.

                 PURCHASE PRICE - Incentive Stock Options will be granted at a
         price not less than 100% of the average fair market value of the
         shares on the date of grant.  Shares available for option or so
         optioned and the option price thereof will be increased or decreased
         proportionately for any share split, share dividends or other similar
         share adjustment.  The Committee may make appropriate discretionary
         adjustments or conversion for any future mergers, exchanges of
         securities, reorganizations, liquidations in whole or in part or any
         other corporate event which would result in a substantial diminution
         of the economic benefit intended for the holders of options granted
         under the 1991 Plan.  The purchase price shall be paid in full upon
         the exercise of an option either in cash or in whole or in part with
         Common Shares previously owned by an optionee and valued on the basis
         of fair market value on the date the option is exercised.  The ability
         to pay the purchase price with Common Shares would permit possible
         "pyramiding" in successive and substantially simultaneous exercises.
         Such pyramiding might permit an option holder to start with a
         relatively small number of shares and exercise all of his or her then
         exercisable share options with no additional cash (except for
         fractional share adjustments) and no more investment than the original
         shares.  On May 8, 1992, all prior stock option award agreements were
         retroactively amended to limit pyramiding activity by requiring a six
         month share holding period and all subsequent stock option award
         agreements have reflected the six month share holding period
         requirement.  Although it is not obligated to do so, the Committee may
         authorize the acceptance of an optionee's surrender of his or her
         right to exercise an option, or portion thereof, and the payment to
         the optionee of the difference between the fair market value of the
         shares underlying the option or portion thereof and the option price
         thereof, in cash, or partly in cash and partly in shares.

                 CONDITIONS OF EXERCISE OF OPTION - Except with respect to
         stock option awards made the Committee after May 9, 1994 to Senior
         Executive Officers, each option may be exercised in whole or in part
         (in lots of ten shares or a multiple thereof) commencing one year from
         the date of grant and ending five or ten years from such date, as
         applicable, but no more than five years after termination of
         employment by reason of death, disability or retirement, or three
         months after termination of employment for any reason other than the
         above.  In the case of death, the option may be exercised,
         respectively, by the employee or his or her heirs only to the extent
         that the employee was entitled thereto on the date of termination of
         employment or death.  No option shall be transferable  by the
         employee's heirs, except by will or by the laws of descent or
         distribution.  Beginning one year from the date of grant and subject
         to the provisions of Section 422A of the Internal Revenue Code of 1986
         with respect to the limitation on the aggregate fair market value of
         options exercisable for the first time in any calendar year, an option
         may be exercised by an employee at a cumulative rate not in excess of
         50% of the total shares optioned during the second year, 75% during
         the third year and 100% thereafter.

                 CHANGE IN CONTROL - (For the definition of Change in Control, 
         please refer to Page I-8.)





                                      I-11

CURRENT STATUS OF THE 1991 PLAN

         As of December 31, 1995, the authorized share issuance authority which
remained in the plan (1,500,000 shares issuance authority, less awards and
cancellations) was 279,257 shares.


CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         GENERAL - The following is a brief description of the federal income
tax consequences under existing law generally applicable to awards under the
1991 Plan, and is not intended to represent an analysis of the tax rules as
applied to any individual recipient.  EACH PARTICIPANT IS URGED TO CONSULT HIS
OR HER PERSONAL TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE TAX LAWS TO
HIS OR HER PERSONAL CIRCUMSTANCES, CHANGES IN THE LAWS AND THE POSSIBLE EFFECT
OF OTHER TAXES.

         RESTRICTED SHARES - A participant will normally not recognize taxable
income upon an award of Restricted Shares, and Medusa will not be entitled to a
deduction until the lapse of the restrictions.  Upon lapse of restrictions, the
participant will then recognize ordinary taxable income in an amount equal to
the fair market value of the Common Shares as to which the restrictions have
lapsed, and Medusa will be entitled to a deduction in the same amount.
However, a participant may elect under Section 83(b) to recognize taxable
ordinary income in the year the Restricted Shares are awarded in an amount
equal to the fair market value of the shares at that time, determined without
regard to the restrictions.  In such event, Medusa will then be entitled to a
deduction in the same amount.  Any gain or loss subsequently recognized by the
participant will be a capital gain or loss.  If, after making a Section 83(b)
election, any Restricted Shares are forfeited, or if the fair market value at
vesting is lower than the amount on which the participant was taxed, the
participant cannot then claim a deduction.

         STOCK OPTIONS - No tax is incurred by the participant (or expense
deductible by Medusa) upon the grant of a nonqualified stock option.  At the
time of exercise of such an option, the difference between the exercise price
and the fair market value of Common Shares will constitute ordinary income.
Medusa will be allowed a deduction equal to the amount of ordinary income
recognized by the participant.  In the case of Incentive Stock Options,
although no income is recognized upon exercise and Medusa is not entitled to a
deduction, the excess of the fair market value of Common Shares on the date of
exercise over the exercise price is treated by the participant as an item of
tax preference for alternative minimum tax purposes.  If the participant does
not dispose of the shares acquired on the exercise of an Incentive Stock Option
within one year after their receipt (and within two years after the grant of
the stock option), gain or loss recognized on the disposition of the shares
will be treated as long-term capital gain or loss.  In the event of an earlier
disposition, the participant may recognize ordinary income and Medusa will be
entitled to a deduction, equal to the amount of such income, when the
participant recognizes income.

         STOCK APPRECIATION RIGHTS - The participant will not recognize any
income at the time of grant of an SAR.  Upon the exercise of an SAR, the cash
and the value of any Common Shares received will constitute ordinary income to
the participant.  Medusa will be entitled to a deduction in the amount of such
income at the time of exercise.

         PERFORMANCE AWARDS - Normally, a participant will not recognize
taxable income upon the award of the above grants.  Subsequently, when the
conditions and requirements for the grants have been satisfied and the payment
determined, any cash received and the fair market value of any Common Shares
received will constitute ordinary income to the participant.  Medusa will also
then be entitled to a deduction in the same amount.

         ALL AWARDS - The Committee has discretion as to any award under the
1991 Plan to award a participant a separate cash amount at exercise, vesting or
lapse of restrictions to meet mandatory tax withholding obligations or
reimburse for any individual taxes paid.  Special tax rules may apply to any
awards granted under the 1991 Plan to individuals subject to Section 16 of the
Act.

Item 6.  Indemnification of Directors and Officers

    Section 1701.13 of the Ohio General Corporation Law, as amended, provides
in relevant part as follows:

                 (E)(1)  A corporation may indemnify or agree to indemnify any
         person who was or is a party or is threatened to be made a party, to
         any threatened, pending or completed action, suit or proceeding,
         whether civil, criminal, administrative or investigative, other than
         an action by or in the right of the corporation, by reason of the fact
         that he is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee or agent of another
         corporation, domestic or foreign, nonprofit or for profit,
         partnership, joint venture, trust or other enterprise, against
         expenses, including attorney's fees, judgments, fines and amounts paid
         in settlement actually and reasonably incurred by him in connection
         with such action, suit or proceeding if he acted in good faith and in
         a manner he reasonably believed to be in or not opposed to the best
         interests of the corporation, and with respect to any criminal action
         or proceeding, had no reasonable cause to believe his conduct was
         unlawful.  The termination of any action, suit or proceeding by
         judgment, order, settlement or conviction, or upon a plea of nolo
         contendere or its equivalent, shall not, of itself create a
         presumption that the person did not act in good faith, and in a manner
         he reasonably believed to be in or not opposed to the best interests
         of the corporation and, with respect to any criminal action or
         proceeding, he had reasonable cause to believe that his conduct was
         unlawful.

                 (2)  A corporation may indemnify or agree to indemnify any
         person who was or is a party or is threatened to be made a party, to
         any threatened, pending or completed action or suit by or in the right
         of the corporation to procure a judgment in its favor by reason of the
         fact that he is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee or an agent of another
         corporation, domestic or foreign, nonprofit or for profit,
         partnership, joint venture, trust or other enterprise, against
         expenses, including attorney's fees, actually and reasonably incurred
         by him in connection with the defense or settlement of such action or
         suit if he acted in good faith and in a manner he reasonably believed
         to be in or not opposed to the best interests of the corporation,
         except that no indemnification shall be made in respect of any of the
         following:

                          (a)  Any claim, issue or matter as to which such
                 person is adjudged to be liable for negligence or misconduct
                 in the performance of his duty to the corporation unless, and
                 only to the extent that the Court of Common Pleas or the court
                 in which such action or suit was brought determines upon
                 application that, despite the adjudication of liability, but
                 in view of all the circumstances of the case, such person is
                 fairly and reasonably entitled to indemnity for such expenses
                 as the Court of Common Pleas or such other court shall deem
                 proper;

                          (b)  Any action or suit in which the only liability
                 asserted against a director is pursuant to Section 1701.95 of
                 the Revised Code.

                 (3)  To the extent that a director, trustee, officer, employee
         or agent has been successful on the merits or otherwise in defense of
         any action, suit or proceeding referred to in division (E)(1) and (2)
         of this section, or in defense of any claim, issue or matter therein,
         he shall be indemnified against expenses, including attorney's fees,
         actually and reasonably incurred by him in connection with the action,
         suit or proceeding.

                                     II-2
<PAGE>   17
                 (4)  Any indemnification under divisions (E)(1) and (2) of
         this section, unless ordered by a court, shall be made by the
         corporation only as authorized in the specific case upon a
         determination that indemnification of the director, trustee, officer,
         employee or agent is proper in the circumstances because he has met
         the applicable standard of conduct set forth in divisions (E)(1) and
         (2) of this section. Such determination shall be made as follows:

                          (a)  By a majority vote of a quorum consisting of
                 directors of the indemnifying corporation who were not and are
                 not parties to or threatened with any such action, suit or
                 proceeding;

                          (b)  If the quorum described in division (E)(4)(a) of
                 this section is not obtainable or if a majority vote of a
                 quorum of disinterested directors so directs, in a written
                 opinion by independent legal counsel other than an attorney,
                 or a firm having associated with it an attorney, who has been
                 retained by or who has performed services for the corporation
                 or any person to be indemnified within the past five years;

                          (c)  By the shareholders; or

                          (d)  By the Court of Common Pleas or the court in 
                 which such action, suit or proceeding was brought.

        Any determination made by the disinterested directors under division
(E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this
section shall be promptly communicated to the person who threatened or brought
the action or suit, by or in the right of the corporation under division (E)(2)
of this section, and within ten days after receipt of such notification, such
person shall have the right to petition the Court of Common Pleas or the court
in which such action or suit was brought to review the reasonableness of such
determination.

     (5)      (a)  Unless at the time of a director's act or omission that
     is the subject of an action, suit or proceeding referred to in divisions
     (E)(1) and (2) of this section, the articles or the regulations of a
     corporation state by specific reference to this division that the
     provisions of the division do not apply to the corporation and unless the
     only liability asserted against a director in an action, suit or
     proceeding referred to in divisions (E)(1) and (2) of this section is
     pursuant to Section 1701.95 of the Revised Code, expenses, including
     attorney's fees, incurred by a director in defending the action, suit or
     proceeding shall be paid by the corporation as they are incurred, in
     advance of the final disposition of the action, suit or proceeding upon
     receipt of an undertaking by or on behalf of the director in which he
     agrees to do both of the following:
              
                     (i)  Repay such amount if it is proved by clear and 
              convincing evidence in a court of competent jurisdiction that 
              his action or failure to act involved an act or omission 
              undertaken with deliberate intent to cause injury to the 
              corporation or undertaken with reckless disregard for the best
              interests of the corporation;

                     (ii)  Reasonably cooperate with the corporation concerning
              the action, suit or proceeding.





                                      II-3
<PAGE>   18
                          (b)  Expenses, including attorney's fees, incurred by
                 a director, trustee, officer, employee or agent in defending
                 any action, suit or proceeding referred to in divisions (E)(1)
                 and (2) of this section, may be paid by the corporation as
                 they are incurred, in advance of the final disposition of the
                 action, suit or proceeding as authorized by the directors in
                 the specific case upon the receipt of an undertaking by or on
                 behalf of the director, trustee, officer, employee or agent to
                 repay such amount, if it ultimately is determined that he is
                 not entitled to be indemnified by the corporation.

                 (6)  The indemnification authorized by this section shall not
         be and shall be in addition to, exclusive of, any other rights granted
         to those seeking indemnification under the articles or the regulations
         or any agreement, vote of shareholders or disinterested directors, or
         otherwise, both as to action in his official capacity and as to action
         in another capacity while holding such office, and shall continue as
         to a person who has ceased to be a director, trustee, officer,
         employee or agent and shall inure to the benefit of the heirs,
         executors and administrators of such a person.

                 (7)  A corporation may purchase and maintain insurance or
         furnish similar protection, including but not limited to trust funds,
         letters of credit or self-insurance, on behalf of or for any person
         who is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee or agent of another
         corporation, domestic or foreign, nonprofit or for profit,
         partnership, joint venture, trust or other enterprise, against any
         liability asserted against him and incurred by him in any such
         capacity, or arising out of his status as such, whether or not the
         corporation would have the power to indemnify him against such
         liability under this section.  Insurance may be purchased from or
         maintained with a person in which the corporation has a financial
         interest.

                 (8)  The authority of a corporation to indemnify persons
         pursuant to divisions (E)(1) and (2) of this section does not limit
         the payment of expenses as they are incurred, indemnification,
         insurance or other protection that may be provided pursuant to
         divisions (E)(5), (6) and (7) of this section.  Divisions (E)(1) and
         (2) of this section do not create any obligation to repay or return
         payments made by the corporation pursuant to divisions 
         (E)(5), (6) or (7).

                 (9)  As used in this division, references to "corporation"
         includes all constituent corporations in a consolidation or merger and
         the new or surviving corporation, so that any person who is or was a
         director, officer, employee or agent of such a constituent
         corporation, or is or was serving at the request of such constituent
         corporation as a director, trustee, officer, employee or agent of
         another corporation, domestic or foreign, nonprofit or for profit,
         partnership, joint venture, trust or other enterprise, shall stand in
         the same position under this section with respect to the new or
         surviving corporation as he would if he had served the new or
         surviving corporation in the same capacity.

Article X of the Company's Articles of Incorporation provides as follows:

                                   ARTICLE X

                                INDEMNIFICATION

    SECTION 1.  RIGHT TO INDEMNIFICATION.  Each person who was or is made a
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he, or a person of
whom he is the legal





                                      II-4
<PAGE>   19
representative, is or was a director or officer of the Corporation or is or was
serving at the request of the Corporation as director, officer, trustee or
agent of another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, trustee or agent or in any other capacity while serving as a
director, officer, trustee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent authorized by the Ohio General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid or to be paid in settlement) reasonably
incurred or suffered by such person in connection therewith and such
indemnification shall continue as to a person who has ceased to be a director,
officer, trustee or agent and shall inure to the benefit of his or her heirs,
executors and administrators; provided, however, that, except, as provided in
Section 2 of this Article X, the Corporation shall indemnify any such person
seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation.  The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding as incurred and in advance of its final
disposition; provided, however, that the payment of such expenses as incurred
and in advance of the final disposition of a proceeding shall be made only upon
delivery to the Corporation of any undertaking required by the Ohio General
Corporation Law.  The Corporation may, by action of its Board of Directors,
provide indemnification to agents of the Corporation and to employees of the
Corporation who are not directors or officers of the Corporation with the same
scope and effect as the foregoing indemnification of directors and officers.

    SECTION 2.  RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under Section 1 of
this Article X is not paid in full by the Corporation within thirty days after
a written claim has been received by the Corporation, the claimant may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim and, if successful in whole or in part, the claimant shall be
entitled to be paid also the expense of prosecuting such claim.  It shall be a
defense to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding as incurred and in advance of its
final disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the Ohio General Corporation Law for
the Corporation to indemnify the claimant for the amount claimed, but the
burden of proving such defense shall be on the Corporation.  Neither the
failure of the Corporation (including its Board of Directors, independent legal
counsel, or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the Ohio General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or
its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

    SECTION 3.  NON-EXCLUSIVITY OF RIGHTS.  The right to indemnification and
the payment of expenses incurred in defending a proceeding in advance of its
final disposition conferred in this Article X shall not be exclusive of any
other right which any person may have or hereafter acquire under any statute,
provision of the Articles or the Regulations of the Corporation, agreement,
vote of shareholders or disinterested directors or otherwise.





                                      II-5
<PAGE>   20
    SECTION 4.  INSURANCE.  The Corporation may maintain insurance or furnish
similar protection, including but not limited to trust funds, letters of credit
or self-insurance, on behalf of or for itself and any person who is or was a
director, officer, employee or agent of the Corporation or is or was serving at
the request of the Corporation as a director, trustee, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in
any such capacity or arising out of his status as such, whether or not the
Corporation would have the power to indemnify such person against such
liability under the Ohio General Corporation Law.

    c)           1)  The undersigned registrant hereby undertakes to

         annual report to shareholders for its last fiscal year, unless such
         employee otherwise has received a copy of such report, in which case
         the registrant shall state in the prospectus that it will promptly
         furnish, without charge, a copy of such report on written request of
         the employee.  If the last fiscal year of the registrant has ended

                 2)  The undersigned registrant hereby undertakes to transmit
         or cause to be transmitted to all employees participating in the Plan,
         who do not otherwise receive such material as shareholders of the
         registrant, at the time and in the manner such material is sent to its

    h)           Insofar as indemnification for liability arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by its is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

  SECTION 1. SERIES; DESIGNATIONS; AMOUNTS.  The Class A Preferred Shares may
be issued, from time to time, in one or more series, with such designations and
other terms permitted by the Ohio General Corporation Law as shall be stated in
the resolution or resolutions providing for the issue of such series adopted by
the Board of Directors.  The Board of Directors, in such resolution or
resolutions (a copy of which shall be filed and recorded as required by law),
is also expressly authorized to fix:

        (a)     The distinctive serial designations and the division of
    such shares into series and the number of shares of a particular series,
    which may be increased or decreased by a resolution or resolutions adopted
    by the Board of Directors (a copy of which shall be filed and recorded as
    required by law), provided, that no decrease shall reduce the number of
    Class A Preferred Shares to a number less than the number of shares thereof
    then outstanding plus the number of shares reserved or required for
    issuance upon the exercise of outstanding options, rights or warrants to
    acquire Class A Preferred Shares;
                
        (b)     The annual dividend rate for the particular series, and the
    date or dates from which dividends on all shares of such series shall be
    cumulative, if dividends on shares of the particular series shall be
    cumulative;

        (c)     The redemption price or prices, if any, for the particular
    series;

        (d)     The right, if any, of the holders of a particular series to
    convert such shares into Common Shares (but not into preferred shares of
    any other class or series) and the terms and conditions of such
    conversions;

        (e)     The obligation, if any, of the Corporation to purchase and
    retire or redeem shares of a particular series as a sinking fund or
    redemption or purchase account, the terms thereof and the redemption price

    or redemption or purchase account; and

        (f)     Any restrictions on the issuance of shares of any class or 
    series.

   SECTION 2. STATUS OF SHARES WITHIN SERIES AND OF VARIOUS SERIES.  All Class
A Preferred Shares of any one series shall be alike in every particular and all
series shall rank equally and be identical in all respects except insofar as
they may vary with respect to the matters which the Board of Directors is
hereby expressly authorized to determine in the resolution or resolutions
providing for the issue of any series of the Class A Preferred Shares.

   SECTION 3. DIVIDENDS AND DISTRIBUTIONS.  The holders of Class A Preferred
Shares, in preference to the holders of Class B Preferred Shares, Class C
Preferred Shares, Common Shares and all shares of the Corporation of any other
class ranking junior to the Class A Preferred Shares, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds
legally available for the purpose, dividends in the amounts and at the times
stated in the resolution or resolutions adopted by the Board of Directors which
provide for the issue of such series, respectively.

   SECTION 4. VOTING RIGHTS.  The holders of Class A Preferred Shares shall
have the following voting rights:

        (a)         Each Class A Preferred Share shall entitle the holder
    thereof to one vote on all matters submitted to a vote of the shareholders
    of the Corporation.  No adjustment of the voting rights of holders of Class
    A Preferred Shares shall be made in the event of an increase or decrease in
    the number of Class B Preferred Shares, Class C Preferred Shares or Common
    Shares authorized or issued or in the event of a share split or combination
    of the Class B Preferred Shares, Class C Preferred Shares or Common Shares
    or in the event of a share dividend on any class of shares payable solely
    in Class B Preferred Shares, Class C Preferred Shares or Common Shares;

    required by law, the holders of Class A Preferred Shares, the holders of

    rights shall vote together as one class on all matters submitted to a vote
    of shareholders of the Corporation;

    Preferred Shares shall be in arrears in an aggregate amount equal to or
    exceeding the amounts of dividends payable thereon for six quarterly
    dividend periods, then the holders of such Class A Preferred Shares shall
    have the exclusive right, voting as a single class, to elect two directors
    of the Company, and the remaining directors to be elected shall be elected
    by the other class or classes of shares entitled to vote therefor, at each
    meeting of the shareholders held for the purpose of electing directors,
    until such time as all dividend arrearages on the Class A Preferred Shares
    shall have been paid in full and the current dividend thereon for the then
    current dividend period shall have been declared and paid or set aside for
    payment, at which time the right of the holders of such Class A Preferred
    Shares to elect two directors voting as a single class shall terminate,
    except as herein or by law expressly provided, subject to revesting in the
    event of each and every other subsequent arrearage of the amount indicated
    above; and

        (d)         Except as otherwise provided in these Articles or as
    required by law, holders of Class A Preferred Shares shall have no special
    voting rights and their approval shall not be required (except to the
    extent they are entitled to vote with holders of Class B Preferred Shares,
    Class C Preferred Shares, Common Shares and any other shares of the
    Corporation of any class having general voting rights as herein provided)
    for taking any corporate action.

     SECTION 5.  CERTAIN RESTRICTIONS.

  (a)    Whenever (i) quarterly dividends or other dividends or distributions
payable on any series of the Class A Preferred Shares as provided in Section 3
are in arrears or (ii) the full dividends on all series of the Class A
Preferred Shares for the then current respective dividend periods shall not
have been paid, or declared and a sum sufficient for the payment thereof set
apart, then and thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on all Class A Preferred Shares
outstanding shall have been paid in full, and the full dividends thereon for
the then current respective dividend periods shall have been paid, or declared

    on any shares ranking on a parity (either as to dividends or upon
    liquidation, dissolution or winding up) with the Class A Preferred Shares,
    except dividends paid ratably on the Class A Preferred Shares and all such
    parity shares on which dividends are payable or in arrears in proportion to
    the total amounts to which the holders of all such shares are then
    entitled;

        (iii)       redeem or purchase or otherwise acquire for consideration
    any shares ranking junior (either as to dividends or upon liquidation,
    dissolution or winding up) to the Class A Preferred Shares, provided that
    the Corporation may at any time redeem, purchase or otherwise acquire any
    such junior shares in exchange for shares of the Corporation ranking junior
    (both as to dividends and upon dissolution, liquidation or winding up) to
    the Class A Preferred Shares; or 

        (iv)        redeem or purchase or otherwise acquire for consideration
    any Class A Preferred Shares, or any shares ranking on a parity with the
    Class A Preferred Shares, except in accordance with a purchase offer made

    all holders of all series and classes of such shares upon such terms as the
    Board of Directors, after consideration of the respective annual dividend

    and classes, shall determine in good faith will result in fair and
    equitable treatment among the respective series and classes.

Corporation to purchase or otherwise acquire for consideration any shares of
the Corporation unless the Corporation could, under paragraph (a) of this
Section 5, purchase or otherwise acquire such shares at such time and in such

   SECTION 6. REACQUIRED SHARES.  Any Class A Preferred Shares purchased or
otherwise acquired by the Corporation in any manner whatsoever shall be retired
and cancelled promptly after the acquisition thereof.  All such shares shall
upon their cancellation become authorized but unissued Class A Preferred Shares
and may be reissued as part of a new series of Class A Preferred Shares subject

Class A Preferred Shares unless, prior thereto, the holders of Class A
Preferred Shares of each series shall have received the amount stated in the
resolution or resolutions adopted by the Board of Directors which provide for
the issue of such series, respectively, plus an amount equal to accrued and
unpaid dividends and distributions thereon, whether or not declared, to the
date of such payment, or (ii) to the holders of shares ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with
the Class A Preferred Shares, except distributions made ratably on the Class A
Preferred Shares and all such parity shares in proportion to the total amounts
to which the holders of such shares are entitled upon such liquidation,
dissolution or winding up.  The remaining net assets of the Corporation (after
receipt by the holders of Class A Preferred Shares and holders of such parity
shares of the full amounts, respectively, provided for in this Section 7) shall
be distributed solely among the holders of Class B Preferred Shares, Class C
Preferred Shares, the Common Shares, and all shares of the Corporation of any

rights of the Class A Preferred Shares so as to affect them adversely without
the affirmative vote of the holders of at least two-thirds of the outstanding
Class A Preferred Shares, voting together as a single class, and (ii) which
would so adversely affect one or more but less than all series of Class A
Preferred Shares without the affirmative vote of at least two-thirds of the
outstanding shares of such affected series, voting together as a single class.

  B.     PROVISIONS APPLICABLE TO CLASS B PREFERRED SHARES.

  SECTION 1. SERIES;  DESIGNATIONS, AMOUNTS.  The Class B Preferred Shares may
be issued, from time to time, in one or more series, with such designations and

the Board of Directors.  The Board of Directors, in such resolution or
resolutions (a copy of which shall be filed and recorded as required by
law), is also expressly authorized to fix:

        (a)         The distinctive serial designations and the division of
    such shares into series and the number of shares of a particular series,
    which may be increased or decreased by a resolution or resolutions adopted
    by the Board of Directors (a copy of which shall be filed and recorded as
    required by law), provided, that no decrease shall reduce the number of
    Class B Preferred Shares to a number less than the number of shares thereof
    then outstanding plus the number of shares reserved or required for
    issuance pursuant to the exercise of outstanding options, rights or
    warrants to acquire Class B Preferred Shares;

        (b)         The annual dividend rate for the particular series, and the

    convert such shares into Common Shares (but not into preferred shares of
    any other class or series) and the terms and conditions of such
    conversions;

                                      V-4
<PAGE>   6
      (e) The obligation, if any, of the Corporation to purchase and retire or
   redeem shares of a particular series as a sinking fund or redemption or
   purchase account, the terms thereof and the redemption price or prices per
   share for such series redeemed pursuant to the sinking fund or redemption or
   purchase account; and

      (f) Any restrictions on the issuance of shares of any class or series.

   SECTION 2. STATUS OF SHARES WITHIN SERIES AND OF VARIOUS SERIES. All Class B
Preferred Shares of any one series shall be alike in every particular and all

they may vary with respect to the matters which the Board of Directors is
hereby expressly authorized to determine in the resolution or resolutions
providing for the issue of any series of Class B Preferred Shares.

   SECTION 3. DIVIDENDS AND DISTRIBUTIONS. Subject to the rights of the holders
of any shares of any class or series ranking prior and superior to the Class B
Preferred Shares, the holders of Class B Preferred Shares in preference to the
holders of Class C Preferred Shares, Common Shares, and all shares of the
Corporation of any other class ranking junior to the Class B Preferred Shares,
shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for the purpose, dividends in the
amounts and at the times stated in the resolution or resolutions adopted by the
Board of Directors which provide for the issue of such series, respectively.

   SECTION 4. VOTING RIGHTS. The holders of Class B Preferred Shares shall have
the following voting rights:

      (a) Each Class B Preferred Share shall entitle the holder thereof to one
   vote on all matters submitted to a vote of the shareholders of the
   Corporation. No adjustment of the voting rights of holders of Class B
   Preferred Shares shall be made in the event of an increase or decrease in
   the number of Class A Preferred Shares, Class C Preferred Shares or Common
   Shares authorized or issued or in the event of a share split or combination
   of the Class A Preferred Shares, Class C Preferred Shares or Common Shares
   or in the event of a share dividend on any class of shares payable solely in
   Class A Preferred Shares, Class C Preferred Shares or Common Shares;

      (b) Except as otherwise provided in these Articles or as required by law,
   the holders of Class A Preferred Shares, the holders of Class B Preferred
   Shares, the holders of Class C Preferred Shares and the holders of Common
   Shares and any other shares of the Corporation of any class having general
   voting rights shall vote together as one class on all matters submitted to a
   vote of shareholders of the Corporation;

      (c) If at any time or times dividends payable on any Class B Preferred
   Shares shall be in arrears in an aggregate amount equal to or exceeding the
   amounts of dividends payable thereon for six quarterly dividend periods,
   then the holders of such Class B Preferred Shares shall have the exclusive
   right, voting as a single class, to elect two directors of the Company, and
   the remaining directors to be elected shall be elected by the other class or
   classes of shares entitled to vote therefor, at each meeting of the
   shareholders held for the purpose of electing directors, until such time as
   all dividend arrearages on the Class B Preferred Shares shall have been paid
   in full and the current dividend thereon for the then current dividend
   period shall have been declared and paid or set aside for payment, at which
   time the right of the holders of such Class B Serial Preferred Shares to
   elect two directors voting as a single class shall terminate, except as
   herein or by law expressly provided, subject to revesting in the event of
   each and every other subsequent arrearage of the amount indicated above; and

      (d) Except as otherwise provided in these Articles or as required by law,
   holders of Class B Preferred Shares shall have no special voting rights and
   their approval shall not be required (except to the extent they are entitled
   to vote with holders of Class A Preferred Shares, Class C Preferred Shares,
   Common Shares and any other shares of the Corporation of any class having
   general voting rights as herein provided) for taking any corporate action.

in arrears of (ii) the full dividends on all series of the Class B Preferred
Shares for the then current respective dividend periods shall not have been
paid, or declared and a sum sufficient for the payment thereof set apart, then
and thereafter and until all accrued and unpaid dividends and distributions,

   shares ranking junior (either as to dividends or upon liquidation,
   dissolution or winding up) to the Class B Preferred Shares, other than a
   dividend payable in shares ranking junior (both as to dividends and upon
   liquidation, dissolution or winding up) to the Class B Preferred Shares;

      (ii)     declare or pay dividends, or make any other distributions, on
   any shares ranking on a parity (either as to dividends or upon liquidation,
   dissolution or winding up) with the Class B Preferred Shares, except
   dividends paid ratably on the Class B Preferred Shares and all such parity
   shares on which dividends are payable or in arrears in proportion to the
   total amounts to which the holders of all such shares are then entitled;

      (iii) redeem or purchase or otherwise acquire for consideration any
   shares ranking junior (either as to dividends or upon liquidation,
   dissolution or winding up) to the Class B Preferred Shares, provided that
   the Corporation may at any time redeem, purchase or otherwise acquire any
   such junior shares in exchange for shares of the Corporation ranking junior
   (both as to dividends and upon dissolution, liquidation or winding up) to
   the Class B Preferred Shares; or

      (iv) redeem or purchase or otherwise acquire for consideration any Class
   B Preferred Shares, or any shares ranking on a parity with the Class B
   Preferred Shares, except in accordance with a purchase offer made in writing
   of by publication (as determined by the Board of Directors) to all holders
   of all series and classes of such shares upon such terms as the Board of
   Directors, after consideration of the respective annual dividend rates and
   other relative rights and preferences of the respective series and classes,
   shall determine in good faith will result in fair and equitable treatment
   among the respective series and classes.

   (b) The Corporation shall not permit any subsidiary of the Corporation to

or otherwise acquire such shares at such time and in such manner.

   SECTION 6. REACQUIRED SHARES. Any Class B Preferred Shares purchased or
otherwise acquired by the Corporation in any manner whatsoever shall be retired
and cancelled promptly after the acquisition thereof.  All such shares shall
upon their cancellation become authorized but unissued Class B Preferred Shares

to the conditions and restrictions on issuance set forth in these Articles, or
in any resolution or resolutions adopted by the Board of Directors which
provide for the issue of a series of preferred shares of the Corporation of any
class, or as otherwise required by law.

   SECTION 7. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (i)
to the holders of Class C Preferred Shares, Common Shares and all shares of the
Corporation of any other class ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Class B Preferred Shares unless,
prior thereto, the holders of Class B Preferred Shares of each series shall
have received the amount stated in the resolution or resolutions adopted by the
Board of Directors which provide for the issue of such series, respectively,
plus an amount equal to accrued and unpaid dividends and distributions thereon,

dissolution or winding up) with the Class B Preferred Shares, except
distributions made ratably on the Class B Preferred Shares and all such parity

Preferred Shares and holders of such parity shares of the full amounts,

                                      V-6
<PAGE>   8
respectively, provided for in this Section 7) shall be distributed solely among

the Corporation of any other class ranking junior to the Class B Preferred
Shares according to the provisions hereof and their respective shares.

   SECTION 8. AMENDMENT. These Articles shall not be amended in any manner (i)
which would materially alter or change the powers, preferences or special
rights of the Class B Preferred Shares so as to affect them adversely without
the affirmative vote of the holders of at least two-thirds of the outstanding
Class B Preferred Shares, voting together as a single class, and (ii) which
would so adversely affect one or more but less than all series of Class B
Preferred Shares without the affirmative vote of at least two-thirds of the

   C. PROVISIONS APPLICABLE TO CLASS C PREFERRED SHARES.

   SECTION 1. DIVIDENDS AND DISTRIBUTIONS.

   (a) Subject to the rights of the holders of any shares of the Corporation
of any series or class ranking prior and superior to the Class C Preferred
Shares with respect to dividends, the holders of Class C Preferred Shares, in
preference to the holders of Common Shares, shall be entitled to receive, when,
as and if declared by the Board of Directors out of funds legally available for
the purpose, quarterly dividends payable in cash on such day (to be designated
from time to time by the Board of Directors, or if not so designated, then the
fifteenth day) during the months of March, June, September, and December in
each year (each such date being referred to herein as a "Quarterly Dividend
Payment Date") after the first issuance of a Class C Preferred Share or
fraction thereof, in an amount per share (rounded to the nearest cent) equal to
the greater of (i) $1 or (ii) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions, other than a dividend payable in
Common Shares or a subdivision of the outstanding Common Shares (by
reclassification or otherwise), declared on the Common Shares since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any Class C
Preferred Share or fraction thereof. In the event the Corporation shall at any
time declare or pay any dividend on the Common Shares payable in Common Shares,
or effect a subdivision or combination or consolidation of the outstanding
Common Shares (by reclassification or otherwise than by payment of a dividend
in Common Shares) into a greater or lesser number of Common Shares, then in
each such case the amount to which holders of Class C Preferred Shares were
entitled immediately prior to such event under clause (ii) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of Common Shares outstanding immediately after
such event and the denominator of which is the number of Common Shares that
were outstanding immediately prior to such event.

   (b) The Corporation shall declare a dividend or distribution on the Class C
Preferred Shares as provided in paragraph (a) of this Section 1 immediately
after it declares a dividend or distribution on the Common Shares (other than a
dividend payable in Common Shares); provided that, in the event no dividend or
distribution shall have been declared on the Common Shares during the period
between any Quarterly Dividend Payment Date and the next subsequent Quarterly
Dividend Payment Date, a dividend of $1 per share on the Class C Preferred
Shares shall nevertheless be payable on such subsequent Quarterly Dividend
Payment Date.

   (c) Dividends shall begin to accrue and be cumulative on outstanding Class C
Preferred Shares from the Quarterly Dividend Payment Date next preceding the
date of issue of such shares, unless the date of issue of such shares is prior
to the record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is
a date after the record date for the determination of holders of Class C
Preferred Shares entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
Class C Preferred Shares in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.
The

                                      V-7
<PAGE>   9


Board of Directors may fix a record date for the determination of holders of
Class C Preferred Shares entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

        SECTION 2. VOTING RIGHTS. The holders of Class C Preferred Shares shall
have the following voting rights:

        (a) Subject to the provision for adjustment hereinafter set forth, each
       Class C Preferred Share shall entitle the holder thereof to 100 votes on
       all matters submitted to a vote of the shareholders of the Corporation.
       In the event the Corporation shall at any time declare or pay any
       dividend on the Common Shares payable in Common Shares, or effect a
       subdivision or combination or consolidation of the outstanding Common
       Shares (by reclassification or otherwise than by payment of a dividend
       in Common Shares) into a greater or lesser number of Common Shares, then
       in each such case the number of votes per share to which holders of
       Class C Preferred Shares were entitled immediately prior to such event
       shall be adjusted by multiplying such number by a fraction, the
       numerator of which is the number of Common Shares outstanding
       immediately after such event and the denominator of which is the number
       of Common Shares that were outstanding immediately prior to such event.

        (b) Except as otherwise provided in these Articles or required by law,
       the holders of Class A Preferred Shares, the holders of Class B
       Preferred Shares, the holders of Class C Preferred Shares and the
       holders of Common Shares and any other shares of the Corporation of any
       class having general voting rights shall vote together as one class on
       all matters submitted to a vote of shareholders of the Corporation.

        (c) Except as otherwise provided in these Articles or as required by
       law, holders of Class C Preferred Shares shall have no special voting
       rights and their approval shall not be required (except to the extent
       they are entitled to vote with holders of Class A Preferred Shares,
       Class B Preferred Shares, Common Shares and any other shares of the
       Corporation of any class having general voting rights as herein
       provided) for taking any corporate action.

       SECTION 3. CERTAIN RESTRICTIONS.

        (a)   Whenever (i) quarterly dividends or other dividends or
distributions payable on the Class C Preferred Shares as provided in Section 1
are in arrears, or (ii) the full dividends on the Class C Preferred Shares for
the then current dividend period shall not have been paid, or declared and a
sum sufficient for the payment thereof set apart, then and thereafter and until
all accrued and unpaid dividends and distributions, whether or not declared, on
all Class C Preferred Shares outstanding shall have been paid in full, and the
full dividends thereon for the then current dividend period shall have been
paid, or declared and a sum sufficient for the payment thereof set apart the
Corporation shall not:

             (i) declare or pay dividends, or make any other distributions, on
             the Common Shares; or

             (ii) redeem or purchase or otherwise acquire for consideration
             any Common Shares.

        (b)   The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
the Corporation unless the Corporation could, under paragraph (a) of this
Section 3, purchase or otherwise acquire such shares at such time and in such
manner.

        SECTION 4. REACQUIRED SHARES. Any Class C Preferred Shares purchased or
otherwise acquired by the Corporation in any manner whatsoever shall be retired
and cancelled promptly after the acquisition thereof.  All such shares shall
upon their cancellation become authorized but unissued Class C Preferred Shares
and may be reissued subject to the conditions and restrictions on issuance set
forth in these Articles, or in any resolution or resolutions adopted by the
Board of Directors which provide for the issue of a series of preferred shares
of the Corporation of any class, or as otherwise required by law.

        SECTION 5. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution
shall be made to the holders of Common Shares unless, prior thereto, the
holders of Class C Preferred Shares shall have received $100 per share, plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether
or not declared, to the date of such payment, provided that the holders of
Class C Preferred Shares shall be entitled to receive an aggregate amount per
share, subject

                                      V-8
<PAGE>   10


to the provision for adjustment hereinafter set forth, equal to 100 times the
aggregate amount to be distributed per share to holders of Common Shares. In
the event that the Corporation shall at any time declare or pay any dividend on
Common Shares payable in Common Shares, or effect a subdivision or combination
or consolidation of the outstanding Common Shares (by reclassification or
otherwise than by payment of a dividend in Common Shares) into a greater or
lesser number of Common Shares, then in each such case the aggregate amount to
which holders of Class C Preferred Shares were entitled immediately prior to
such event under the proviso in the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
Common Shares outstanding immediately after such event and the denominator of
which is the number of Common Shares that were outstanding immediately prior to
such event.

        SECTION 6. CONSOLIDATION, MERGER; ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
Common Shares are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each Class C Preferred Share
shall at the same time be similarly exchanged or changed into an amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
Common Share is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Shares payable in Common Shares,
or effect a subdivision or combination or consolidation of the outstanding
Common Shares (by reclassification or otherwise than by payment of a dividend
in Common Shares) into a greater or lesser number of Common Shares, then in
each such case the amount set forth in the preceding sentence with respect to
the exchange or change of Class C Preferred Shares shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
Common Shares outstanding immediately after such event and the denominator of
which is the number of Common Shares that were outstanding immediately prior to
such event.

        SECTION 7. NO REDEMPTION. The Class C Preferred Shares shall not be
redeemable.

        SECTION 8. RANK. The Class C Preferred Shares shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all
series of any other class of the Corporation's preferred shares.

        SECTION 9. AMENDMENT. These Articles shall not be amended in any manner
(i) which would materially alter or change the powers, preferences or special
rights of the Class C Preferred Shares so as to affect them adversely without
the affirmative vote of the holders of at least two-thirds of the outstanding
Class C Preferred Shares, voting together as a single class.

   D. PROVISIONS APPLICABLE TO COMMON SHARES.     

        SECTION 1. DIVIDENDS AND DISTRIBUTIONS. Subject to the rights of the
holders of all classes and series of preferred shares of the Corporation, the
holders of Common Shares shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
dividends payable in cash or otherwise.

        SECTION 2. VOTING RIGHTS. 

        (a) Each Common Share shall entitle the holder thereof to one vote on
each matter on which the holders of Common Shares are entitled to vote.

        (b) Except as otherwise provided in these Articles or required by law,
the holders of Class A Preferred Shares, the holders of Class B Preferred
Shares, the holders of Class C Preferred Shares and the holders of Common
Shares and any other shares of the Corporation having general voting rights
shall vote together as one class on all matters submitted to a vote of
shareholders of the Corporation.

   E. NO CUMULATIVE VOTING.

        Notwithstanding the respective voting rights of the holders of shares
of any class or series of the Corporation, no holder of shares of any class or
series shall have the right to cumulate his voting power in the election of
directors.

                            ARTICLE V

                        SHAREHOLDER ACTION

   Subject to the rights of the holders of any series of Class A or Class B
Preferred Shares and except as required by law, (a) any action required or
permitted to be taken by the shareholders of the Corporation may be effected
only at a duly called annual meeting or special meeting of such shareholders
and may not be effected by any consent or approval in writing by such
shareholders, and (b) the right of shareholders to call a meeting of
shareholders shall be restricted to holders of record of shares having in the
aggregate not less than fifty percent (50%) of the total number of votes of all
shares of the Corporation outstanding and entitled to be voted at such meeting.
Advance notice of business to be brought by shareholders before any
shareholders meeting shall be given in the manner provided in the Regulations
of the Corporation. At any annual meeting or special meeting of shareholders of
the Corporation, only such business shall be conducted as shall have been
brought before such meeting in the manner provided by the Regulations of the
Corporation. Notwithstanding anything to the contrary contained in these
Articles, the affirmative vote of the holders of at least 80% of the voting
power of the then outstanding shares of all classes of the Corporation entitled
to vote generally in the election of directors (the "Voting Shares"), voting
together as a single class, shall be required to amend or repeal, or to adopt
any provisions inconsistent with, this Article V.


                            ARTICLE VI

                      PURCHASE OF OWN SHARES

   Subject to the restrictions set forth in these Articles, the Corporation may
purchase, from time to time, and to the extent permitted by the laws of Ohio,
shares of any class or series issued by it. Such permitted purchases may be

now or hereafter authorized and outstanding at the time of any such purchase.

   Shareholder pursuant to paragraph B of this Section 3, the number of Voting
   Shares deemed to be outstanding shall include shares deemed owned through
   application of paragraph C of this Section 3 but shall not include any other
   Voting Shares which may be issuable pursuant to any agreement, arrangement
   or understanding, or upon exercise of conversion rights, warrants or
   options, or otherwise.

     E. "Affiliate" and "Associate" shall have the respective meanings

   of equity security is owned, directly or indirectly, by the Corporation.

     G. "Disinterested Director" means any member of the Board of Directors of
   the Corporation (the "Board") who is unaffiliated with the Interested
   Shareholder and was a member of the Board prior to the time that the
   Interested Shareholder became an Interested Shareholder, and any other
   Director who is unaffiliated with Interested Shareholder and, prior to such

     stock is not listed on such exchange, on the principal United States
     securities exchange registered under the Exchange Act on which such stock
     is listed, or if such stock is not listed on any such exchange, the

<PAGE>   14
information known to them after reasonable inquiry, (a) whether a person is an
Interested Shareholder, (b) the number of Voting Shares beneficially owned by

   SECTION 6. AMENDMENT, REPEAL, ETC. Notwithstanding any other provisions of
these Articles or the Regulations of the Corporation (and notwithstanding the
fact that a lesser percentage may be specified by law, these Articles or the
Regulations of the Corporation, any agreement with any national securities
exchange, or otherwise), the affirmative vote of the holders of at least 80% of
the voting power of the then outstanding Voting Shares, voting together as a
single class, shall be required to amend or repeal, or to adopt any provisions
inconsistent with, this Article VIII.


                            ARTICLE IX

                        BOARD OF DIRECTORS

   SECTION 1. NUMBER. The business and affairs of the Corporation shall be
managed under the direction of the Board of Directors. The number of directors,
subject to the express right of the holders of any series of Class A or Class B
Preferred Shares then outstanding, voting as a class, to elect additional
directors in the event of a dividend arrearage and to the provisions of Section
2 of this Article IX, and subject to the minimum and maximum limitations set
forth in the Regulations of the Corporation, may be fixed or changed from time
to time (i) by the shareholders at a meeting called for the purpose of electing
directors by the affirmative vote of the holders of at least 80% of the voting
power of the then outstanding Voting Shares, voting together as a single class,
and (ii) by the Board of Directors to the extent and in the manner provided in
the Regulations of the Corporation.

   SECTION 2. CLASSES. Commencing with the first election of directors
following the date these Articles become effective, the directors, other than
those who may be elected by the holders of Class A and Class B Preferred Shares
in the event of a dividend arrearage shall be divided, with respect to the time
for which they severally hold office, into three classes consisting of not less
than three directors each. Each class shall consist of an equal number of
directors, except that if the total number of directors shall not be evenly
divisible by three, the remaining director (if there shall be just one) shall
be assigned to Class I, or the remaining directors (if there shall be two)
shall be assigned to Classes I and II, respectively. The term of office of the
directors elected to Class I at such first election shall expire at the first
Annual Meeting of Shareholders after their election, the term of office of the
directors elected to Class II at such first election shall expire at the second
succeeding Annual Meeting of Shareholders after their election and the term of
office of the directors elected to Class III at such first election shall
expire at the third succeeding Annual Meeting of Shareholders after their
election. At each Annual Meeting of Shareholders following the first election
of the classified Board of Directors, directors elected to succeed those
directors whose terms then expire shall be elected for a term of office to
expire at the third succeeding Annual Meeting of Shareholders after their
election, with each director to hold office until such director's successor
shall have been duly elected and qualified. No decrease in the authorized
number of directors shall shorten the term of any incumbent director. The
provisions of this Section 2 shall not apply to any directors elected by the
holders of Class A or Class B Preferred Shares, voting as a class in the event
of an arrearage in the payment of dividends. Any such directors shall not be
classified and shall be elected to serve until the next Annual Meeting of
Shareholders and until their successors have been duly elected and qualified,
or until such arrearage is cured, whichever occurs first.

   SECTION 3. NOMINATION; ELECTION. Advance notice of shareholder nominations
for the election of directors of the Corporation shall be given in the manner
provided in the Regulations of the Corporation.

                               V-13
<PAGE>   15
   SECTION 4. VACANCIES. Subject to the rights of the holders of any series of
Class A or Class B Preferred Shares then outstanding and subject to the right
of shareholders to fill vacancies as provided in the Ohio General Corporation
Law, newly created directorships resulting from any increase in the authorized
number of directors or any vacancies in the Board of Directors resulting from
death, resignation, retirement, disqualification, removal from office or
otherwise may be filled only by a majority vote of the directors then in
office, though less than a majority of the whole authorized number of
directors, and directors so chosen shall hold office for a term expiring at the
Annual Meeting of Shareholders at which the term of the class to which they
have been elected expires and until such director's successor shall have been
duly elected and qualified.

   SECTION 5. REMOVAL. Subject to the rights of the holders of any series of
Class A or Class B Preferred Shares then outstanding, any director, any class
of directors or the entire Board of Directors, may be removed from office at
any time, but only by the affirmative vote of the holders of at least 80% of
the voting power of the then outstanding Voting Shares, voting together as a
single class, or by the directors under the circumstances provided in the Ohio
General Corporation Law.

   SECTION 6. AMENDMENT, REPEAL OR MODIFICATION. Notwithstanding any other
provisions of these Articles or the Regulations of the Corporation (and
notwithstanding that a lesser percentage may be specified by law, these
Articles, the Regulations of the Corporation, any agreement with any national
securities exchange, or otherwise), the affirmative vote of the holders of at
least 80% of the voting power of the then outstanding Voting Shares, voting
together as a single class, shall be required to amend or repeal, or to adopt
any provisions inconsistent with, this Article IX.


                            ARTICLE X

                         INDEMNIFICATION

   SECTION 1. RIGHT TO INDEMNIFICATION. Each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he, or a person of
whom he is the legal representative, is or was a director or officer of the
Corporation or is or was serving at the request of the Corporation as director,
officer, trustee or agent of another corporation or of a partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged action in an
official capacity as a director, officer, trustee or agent or in any other
capacity while serving as a director, officer, trustee or agent, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the Ohio General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than said law permitted the Corporation to provide prior
to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid or to be paid in settlement) reasonably incurred or suffered by such
person in connection therewith and such indemnification shall continue as to a
person who has ceased to be a director, officer, trustee or agent and shall
inure to the benefit of his or her heirs, executors and administrators;
provided, however, that, except as provided in Section 2 of this Article X, the
Corporation shall indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person only if
such proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation. The right to indemnification conferred in this Section shall
be a contract right and shall include the right to be paid by the Corporation
the expenses incurred in defending any such proceeding as incurred and in
advance of its final disposition; provided, however, that the payment of such
expenses as incurred and in advance of the final disposition of a proceeding
shall be made only upon delivery to the Corporation of any undertaking required
by the Ohio General Corporation Law. The Corporation may, by action of its
Board of Directors, provide indemnification to agents of the Corporation and to
employees of the Corporation who are not directors or officers of the
Corporation with the same scope and effect as the foregoing indemnification of
directors and officers.

   SECTION 2. RIGHT OF CLAIMANT TO BRING SUIT. If a claim under Section 1 of
this Article X is not paid in full by the Corporation within thirty days after
a written claim has been received by the Corporation, the claimant may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the

                               V-14
<PAGE>   16
claim and, if successful in whole or in part, the claimant shall be entitled to
be paid also the expense of prosecuting such claim. It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding as incurred and in advance of its final
disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the Ohio General Corporation Law for
the Corporation to indemnify the claimant for the amount claimed, but the
burden of proving such defense shall be on the Corporation. Neither the failure
of the Corporation (including its Board of Directors, independent legal
counsel, or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the Ohio General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or
its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

   SECTION 3. NON-EXCLUSIVITY OF RIGHTS. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Article X shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,
provision of the Articles or the Regulations of the Corporation, agreement,
vote of shareholders or disinterested directors or otherwise.

   SECTION 4. INSURANCE. The Corporation may maintain insurance or furnish
similar protection, including but not limited to trust funds, letters of credit
or self-insurance, on behalf of or for itself and any person who is or was a
director, officer, employee or agent of the Corporation or is or was serving at
the request of the Corporation as a director, trustee, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in
any such capacity or arising out of his status as such, whether or not the
Corporation would have the power to indemnify such person against such
liability under the Ohio General Corporation Law.


                            ARTICLE XI

                       PREEMPTIVE RIGHTS DENIED


   The preemptive right to purchase additional shares or any other securities
of the Corporation is hereby expressly denied to holders of shares of the
Corporation of all classes and series.


                           ARTICLE XII

   Notwithstanding the provisions of Sections 1701.76, 1701.78,
1701.79, 1701.801 and 1701.83 (or any successor statutory sections) which
require the vote of the holders of shares entitling them to exercise two-
thirds of the voting power of the corporation or of any class or classes of
shares thereof for approval of the transactions therein specified, such
approval, unless otherwise expressly prohibited by statute and except as
otherwise expressly required by these Articles, may be obtained bv the vote of
the holders of shares entitling them to exercise a majority of the voting power
of the then outstanding Voting Shares, voting together as a single class, or of
such class or classes.


                           ARTICLE XIII

                      PRIOR ARTICLES SUPERSEDED

   These Amended and Restated Articles of Incorporation shall supersede the
existing 1973 Amended Articles of Incorporation of the Corporation and all
amendments thereto.

                                 ADMINISTRATION

     3.01     COMMITTEE.  The Plan shall be administered by the Organization
and Compensation Committee of the Board ("Committee").  (If at any time the
Committee ceases to exist, or if at any time the Committee shall not comply
with the disinterested administration requirements of Rule 16b-3, the Board
shall select a committee to administer the Plan comprised of not less than two
members of the Board who are disinterested under the requirements of Rule
16b-3.)  The Committee shall have exclusive and final authority in each
determination, interpretation or other action affecting the Plan and its
Participants.  The Committee shall have the sole discretionary authority to
interpret the Plan, to establish and modify administrative rules for the Plan,
to impose such conditions and restrictions on Awards as it determines
appropriate, to cancel Awards (including those made pursuant to other plans of
the Company) and to substitute new Options for previously awarded Options
which, at the time of such substitution, have an exercise price in excess of
the Fair Market Value of the underlying Company Common Shares (including
options granted under other incentive compensation programs of the Company)
with the consent of the recipient, and to take such steps in connection with
the Plan and Awards granted hereunder as it may deem necessary or advisable.
The Committee may, with respect to Participants who are not subject to Section
16(b) of the Exchange Act, delegate such of its powers and authority under the
Plan as it deems appropriate to designated officers or employees of the
Company.

                                     SHARES

Section 10.07, the shares to be offered under the Plan shall be authorized and
unissued Company Common Shares, or issued Company Common Shares which shall
have been reacquired by the Company.  The total number of shares initially
authorized to be issued under the Plan shall be 500,000 Common Shares, which
limit may be increased from time to time in the future by action of the Board
subject to Section 10.15(a).

     4.02     SHARES SUBJECT TO TERMINATED AWARDS.  Company Common Shares
covered by any unexercised portions of terminated Options (including canceled
Options) granted under Article VI, Company Common Shares forfeited as provided
in Section 7.02(a) and Company Common Shares subject to any Awards which are
otherwise surrendered by the Participant may again be subject to new Awards
under the Plan.  Company Common Shares subject to Options, or portions thereof,
which have been surrendered in connection with the exercise of Stock
Appreciation Rights shall not be available for subsequent Awards under the
Plan, but Company Common Shares issued in payment of such Stock Appreciation
Rights shall not be charged against the number of Company Common Shares

                                 PARTICIPATION

     5.01     ELIGIBLE PARTICIPANTS.  Participants in the Plan shall be such
officers and other key employees of the Company and its Subsidiaries, whether
or not members of the Board, as the Committee, in its sole discretion, may
designate from time to time.  The Committee's designation of a Participant in
any year shall not require the Committee to designate such person to receive
Awards or grants in any other year.  The designation of a Participant to
receive awards or grants under one 





                                      A-5
<PAGE>   6
portion of the Plan does not require the Committee to include such Participant
under other portions of the Plan.  The Committee shall consider such factors as
it deems pertinent in selecting Participants and in determining the type and
amount of their respective Awards. Notwithstanding any provision herein to the
contrary, the Committee may grant Awards under the Plan to non-employees who,
in the judgment of the Committee, render significant services to the Company or
any of its Subsidiaries, on such terms and conditions as the Committee deems
appropriate and consistent with the intent of the Plan.                

                                   ARTICLE VI
                  STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

     6.01     OPTION AWARDS.

              (a)    The Committee may grant, to such Participants as the
    Committee may select, Options entitling the Participant to purchase Company
    Common Shares from the Company in such number, provided that such number
    granted shall not exceed 100,000 annually for a Participant (amended March
    27, 1995), at such price, and on such terms and subject to such conditions,
    not inconsistent with the terms of this Plan, as may be established by the
    Committee.  The terms of any Option granted under this Plan shall be set
    forth in an Award Agreement.

              (b)    PURCHASE PRICE OF OPTIONS.  The Purchase Price of each
    Company Common Share which may be purchased upon exercise of any Option
    granted under the Plan, shall be determined by the Committee; provided,
    however, that the Purchase Price of the Company Common Shares purchased
    pursuant to Options designated by the Committee as Incentive Stock Options
    shall be equal to or greater than the Fair Market Value on the Date of
    Grant as required under Section 422A of the Code.  The Committee shall have
    the discretion to provide, in any Award Agreement related to an Option
    granted under the Plan, for a loan from the Company to a Participant of a
    cash amount, or a guaranty by the Company of payment by such Participant to
    a third party of a cash amount loaned by such party to such Participant
    sufficient to allow such Participant to purchase the Company Common Shares
    under such Option, with the Company retaining such Company Common Shares,
    or a portion thereof, as security until such loan is repaid or such
    guaranty expires.

              (c)    DESIGNATION OF INCENTIVE STOCK OPTIONS.  Except as
    otherwise expressly provided in the Plan, the Committee may designate, at
    the time of the grant of each Option, the Option as an Incentive Stock
    Option under Section 422A of the Code.

                     (i)     INCENTIVE STOCK OPTION SHARE LIMITATION.  No
              Participant may be granted Incentive Stock Options under the Plan
              (or any other plans of the Company and its Subsidiaries) which
              would result in shares with an aggregate Fair Market Value
              (measured on the Date of Grant) of more than $100,000 first
              becoming exercisable in any one calendar year.

                     (ii)    OTHER INCENTIVE STOCK OPTION TERMS.  Whenever
              possible, each provision in the Plan and in every Option granted
              under this Plan which is designated by the Committee as an
              Incentive Stock Option shall be interpreted in such a manner as
              to entitle the Option to the tax treatment afforded by Section
              422A of the Code.  If any provision of this Plan or any Option
              designated by the Committee as an Incentive Stock Option shall be
              held not to comply with requirements necessary to entitle such
              Option to such tax treatment, then





                                      A-6
<PAGE>   7
              (A) such provision shall be deemed to have contained from the
              outset such language as shall be necessary to entitle the Option
              to the tax treatment afforded under Section 422A of the Code, and
              (B) all other provisions of this Plan and the Award Agreement
              relating to such Option shall remain in full force and effect.
              If any Award Agreement covering an Option designated by the
              Committee to be an Incentive Stock Option under this Plan shall
              not explicitly include any terms required to entitle such
              Incentive Stock Option to the tax treatment afforded by Section
              422A of the Code, all such terms shall be deemed implicit in the
              designation of such Option and the Option shall be deemed to have
              been granted subject to all such terms.

              (d)    RIGHTS AS A SHAREHOLDER.  A Participant or a transferee of
    an Option pursuant to Section 10.04 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 10.07.

     6.02     STOCK APPRECIATION RIGHTS.

              (a)    STOCK APPRECIATION RIGHT AWARDS.  The Committee is
    authorized to grant to any Participant one or more Stock Appreciation
    Rights, provided that the number of Stock Appreciation Rights granted shall
    not exceed 100,000 annually for a Participant (amended March 27, 1995).
    Such Stock Appreciation Rights may be granted either independent of or in
    tandem with Options granted to the same Participant.  Stock Appreciation
    Rights granted in tandem with Options may be granted simultaneously with,
    or, in the case of Non-Qualified Stock Options, subsequent to, the grant to
    such Participant of the related Option; provided, however, that: (i) any
    Option covering any Company Common Share shall expire and not be
    exercisable upon the exercise of any Stock Appreciation Right with respect
    to the same share, (ii) any Stock Appreciation Right covering any Company
    Common Share shall expire and not be exercisable upon the exercise of any
    related Option with respect to the same share, and (iii) an Option and
    Stock Appreciation Right covering the same Company Common Share may not be
    exercised simultaneously.  Upon exercise of a Stock Appreciation Right with
    respect to a Company Common Share, the Participant shall be entitled to
    receive an amount equal to the excess, if any, of (A) the Fair Market Value
    of a Company Common Share on the date of exercise over (B) the Exercise
    Price of such Stock Appreciation Right established in the Award Agreement,
    which amount shall be payable as provided in Section 6.02(c).

              (b)    EXERCISE PRICE.  The Exercise Price established under any
    Stock Appreciation Right granted under this Plan shall be determined by the
    Committee, but in the case of Stock Appreciation Rights granted in tandem
    with Options shall not be less than the Purchase Price of the related
    Option.  Upon exercise of Stock Appreciation Rights, the number of shares
    subject to exercise under any related Option shall automatically be reduced
    by the number of Company Common Shares represented by the Option or portion
    thereof which are surrendered as a result of the exercise of such Stock
    Appreciation Rights.





                                      A-7
<PAGE>   8
              (c)    PAYMENT OF INCREMENTAL VALUE.  Any payment which may
    become due from the Company by reason of a Participant's exercise of a
    Stock Appreciation Right may be paid to the Participant as determined by
    the Committee (i) all in cash, (ii) all in Company Common Shares, or (iii)
    in any combination of cash and Company Common Shares.  In the event that
    all or a portion of the payment is made in Company Common Shares, the
    number of Company Common Shares delivered in satisfaction of such payment
    shall be determined by dividing the amount of such payment or portion
    thereof by the Fair Market Value on the Exercise Date.  No fractional
    Company Common Shares shall be issued to make any payment in respect of
    Stock Appreciation Rights; if any fractional share would be issuable, the
    combination of cash and Company Common Shares payable to the Participant
    shall be adjusted as directed by the Committee to avoid the issuance of any
    fractional share.

     6.03     TERMS OF STOCK OPTIONS AND STOCK APPRECIATION RIGHTS.

              (a)    CONDITIONS ON EXERCISE.  An Award Agreement with respect
    to Options or Stock Appreciation Rights may contain such waiting periods,
    exercise dates and restrictions on exercise (including, but not limited to,
    periodic installments) as may be determined by the Committee at the time of
    grant.  No Option or Stock Appreciation Right may be exercised in whole or
    in part prior to six months from the Date of Grant thereof, except as set
    forth in Section 6.05.

              (b)    DURATION OF OPTIONS AND STOCK APPRECIATION RIGHTS.
    Options and Stock Appreciation Rights shall terminate after the first to
    occur of the following events:

                     (i)     Expiration of the Option or Stock Appreciation
              Right as provided in the Award Agreement; or

                     (ii)    Termination of the Award as provided in Section
              6.03(e), following the Participant's Termination of Employment; or

                     (iii)   In the case of an Incentive Stock Option, ten
              years from the Date of Grant; or

                     (iv)    Solely in the case of a Stock Appreciation Right
              granted in tandem with an Option, upon the expiration of the
              related Option.

              (c)    ACCELERATION OF EXERCISE TIME.  The Committee, in its sole
    discretion, shall have the right (but shall not in any case be obligated)
    to permit purchase of Company Common Shares subject to any Option or Stock
    Appreciation Right prior to the time such Option or Stock Appreciation
    Right would otherwise become exercisable under the terms of the Award
    Agreement; provided, however, that, in the case of Participants subject to
    Section 16(b) of the Exchange Act, in no event may there be an acceleration
    of exercise to a date prior to six months from the Date of Grant.

              (d)    EXTENSION OF EXERCISE TIME.  In addition to the extensions
    permitted under Section 6.03(e) in the event of Termination of Employment,
    the Committee, in its sole discretion, shall have the right (but shall not
    in any case be obligated) to permit any Option or Stock Appreciation Right
    granted under this Plan to be exercised after its expiration date described
    in Section 6.03(e), subject, however, to the limitations described in
    Section   6.03(b)(i), (iii), and (iv).

                     (i)     TERMINATION OF VESTED OPTIONS AND STOCK
APPRECIATION RIGHTS UPON TERMINATION OF EMPLOYMENT.

                             (A)     TERMINATION.  In the event of Termination
                     of Employment of a Participant other than by reason of
                     death, disability or retirement on the Participant's
                     Normal Retirement Date, to the extent the right to
                     exercise the Option or Stock Appreciation Right has
                     accrued at the date of Termination of Employment, the
                     right of the Participant to exercise the Option or Stock
                     Appreciation Right under the Plan shall terminate three
                     months after the date of such Termination of Employment,
                     unless otherwise provided by the Committee in accordance
                     with Section 6.03(d).

                             (B)     DISABILITY OR RETIREMENT.  Upon a
                     Participant's Termination of Employment by reason of
                     disability or retirement on or after the Participant's
                     Normal Retirement Date, a Participant may, within five
                     years after the Termination of Employment, exercise all or
                     a part of his or her Options which were exercisable upon
                     such Termination of Employment (or which became
                     exercisable at a later date pursuant to Section
                     6.03(e)(ii)), and may, within six months after Termination
                     of Employment, exercise all or a part of his or her Stock
                     Appreciation Rights which he or she was entitled to
                     exercise upon Termination of Employment (or which became
                     exercisable at a later date pursuant to section
                     6.03(e)(ii)).  In no event, however, may any Option or
                     Stock Appreciation Right be exercised later than the date
                     described in Section 6.03(b)(i), (iii) or (iv).

                             (C)     DEATH.  In the event of the death of a
                     Participant while employed by the Company or a Subsidiary
                     or within the additional period of time from the date of
                     the Participant's Termination of Employment and prior to
                     the expiration of the Option or Stock Appreciation Right
                     as permitted in Section 6.03(e)(i)(B) above, to the extent
                     the right to exercise the Option or Stock Appreciation
                     Right accrued as of the date of such Termination of
                     Employment and did not expire during such additional
                     period and prior to the Participant's death, the right of
                     the Participant's Beneficiary to exercise the Option under
                     the Plan shall expire upon the expiration of five years
                     from the date of the Participant's death (but in no event
                     more than five years from the date of the Participant's
                     Termination of Employment by reason of disability or
                     retirement) or on the date of expiration of the Option
                     determined pursuant to Section 6.03(b)(i), (iii) or (iv),
                     whichever is earlier.  Unless otherwise provided by the
                     Committee in accordance with Section 6.03(d), Stock
                     Appreciation Rights shall expire three months after the
                     Participant's death.

                     (ii)    TERMINATION OF UNVESTED OPTIONS OR STOCK
              APPRECIATION RIGHTS UPON TERMINATION OF EMPLOYMENT.  To the
              extent the right to exercise an Option or a Stock Appreciation
              Right, or any portion thereof, has not accrued as of the date of
              Termination of Employment, such right shall expire at the date of
              such Termination of Employment.  Notwithstanding the foregoing,
              the Committee, within its discretion and under such terms as it
              deems appropriate, may permit a Participant who terminates
              employment on the Participant's Normal Retirement Date or Other
              Retirement Date and who will continue to





                                      A-9
<PAGE>   10
              render significant services to the Company or one of its
              Subsidiaries after his or her Termination of Employment, to
              continue vesting in his or her Options and Stock Appreciation
              Rights during the period in which the individual continues to
              render such services.

     6.04     EXERCISE PROCEDURES.  Each Option and Stock Appreciation Right
granted under the Plan shall be exercised by written notice to the Company
which must be received by the officer or employee of the Company designated in
the Award Agreement on or before the expiration date of the Award.  The
Purchase Price of shares purchased upon exercise of an Option granted under the
Plan shall be paid in full in cash by the Participant pursuant to the Award
Agreement; provided, however, that the Committee may (but shall not be required
to) permit payment to be made by delivery to the Company of either (a) Company
Common Shares (which may include Restricted Shares or shares issued in
connection with the exercise of the Option, subject to such rules as the
Committee deems appropriate) or (b) any combination of cash and Company Common
Shares, or (c) such other consideration as the Committee deems appropriate and
in compliance with applicable law (including payment in accordance with a
cashless 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).
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
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 fractional share of Company Common
Shares.  Any part of the Purchase Price paid in cash upon the exercise of any
Option shall be added to the general funds of the Company and may be used for
any proper corporate purpose.  Unless the Committee shall otherwise determine,
any Company Common Shares transferred to the Company as payment of all or part
of the Purchase Price upon the exercise of any Option shall be held as treasury
shares.

     6.05     CHANGE IN CONTROL.

              (a)    OPTIONS.  In the event of a Change in Control, (i) all
    Options outstanding on the date of such Change in Control shall become
    immediately and fully exercisable, and (ii) each Participant who is then
    subject to the provisions of Section 16(b) of the Exchange Act shall be
    permitted to surrender for cancellation within sixty days after such Change
    in Control any Option or portion of an Option to the extent not yet
    exercised (or with respect to an Option or portion of an Option granted to
    such a Participant less than six months prior to the date of the Change in
    Control, within sixty days after the expiration of the six month period
    following the Date of Grant) and to receive a cash payment in an amount
    equal to the excess, if any, of (A) the Adjusted Fair Market Value of the
    Company Common Shares subject to the Option or a portion thereof
    surrendered, over (B) the Purchase Price of such Option.  The provisions of
    this Section 6.05(a) shall not be applicable to any Options granted to a
    Participant if any Change in Control results from such Participant's
    beneficial ownership (within the meaning of Rule 13d-3 under the Exchange
    Act) of Company Common Shares or Company Voting Securities.

              (b)    STOCK APPRECIATION RIGHTS.  In the event of a Change in
    Control, all Stock Appreciation Rights shall become immediately and fully
    exercisable.  Upon any exercise of a Stock Appreciation Right or any
    portion thereof during the 60-day period following the Change in Control,
    (or with respect to a Stock Appreciation Right held by a Participant who is
    then subject to the





                                      A-10
<PAGE>   11
    provisions of Section 16(b) of the Exchange Act which was granted less than
    six months prior to the date of the Change in Control, within sixty days
    after the expiration of the six month period following the Date of Grant)
    the amount payable shall be determined by reference to the Adjusted Fair
    Market Value of the Company Common Shares and shall be paid in cash.  The
    provisions of this Section 6.05(b) shall not be applicable to any Stock
    Appreciation Rights granted to a Participant, if any Change in Control
    results from such Participant's beneficial ownership (within the meaning of
    Rule 13d-3 under the Exchange Act) of Company Common Shares or Company
    Voting Securities.

                                  ARTICLE VII
                               RESTRICTED SHARES

     7.01     RESTRICTED SHARE AWARDS.  The Committee may grant to any
Participant an Award of Company Common Shares in such number, and on such
terms, conditions and restrictions (whether based on performance standards,
periods of service or otherwise) as the Committee shall establish.  The terms
of any Restricted Share Award granted under this Plan shall be set forth in an
Award Agreement which shall contain provisions determined by the Committee and
not inconsistent with this Plan.

              (a)    ISSUANCE OF RESTRICTED SHARES.  As soon as practicable
    after the Date of Grant of a Restricted Share Award by the Committee, the
    Company shall cause to be transferred on the books of the Company, or its
    agent, Company Common Shares, registered on behalf of the Participant,
    evidencing the Restricted shares covered by the Award, but subject to
    forfeiture to the Company as of the Date of Grant if an Award Agreement
    with respect to the Restricted Shares covered by the Award is not duly
    executed by the Participant and timely returned to the Company.  All
    Company Common Shares covered by Awards under this Article VII shall be
    subject to the restrictions, terms and conditions contained in the Plan and
    the Award Agreement entered into by the Participant.  Until the lapse or
    release of all restrictions applicable to an Award of Restricted Shares,
    the share certificates representing such Restricted Shares may be held in
    custody by the Company, its designee, or, if the certificates bear a
    restrictive legend, by the Participant.  Upon the lapse or release of all
    restrictions with respect to an Award as described in Section 7.01(d), one
    or more share certificates, registered in the name of the Participant, for
    an appropriate number of shares as provided in Section 7.01(d), free of any
    restrictions set forth in the Plan and the Award Agreement, shall be
    delivered to the Participant.

              (b)    SHAREHOLDER RIGHTS.  Beginning on the Date of Grant of the
    Restricted Share Award and subject to execution of the Award Agreement as
    provided in Section 7.01(a), the Participant shall become a shareholder of
    the Company with respect to all shares subject to the Award Agreement and
    shall have all of the rights of a shareholder, including, but not limited
    to, the right to vote such shares and the right to receive dividends;
    provided, however, that any Company Common Shares distributed as a dividend
    or otherwise with respect to any Restricted Shares as to which the
    restrictions have not yet lapsed, shall be subject to the same restrictions
    as such Restricted Shares and held or restricted as provided in Section
    7.01(a).

              (c)    RESTRICTION ON TRANSFERABILITY.  None of the Restricted
    Shares may be assigned or transferred (other than by will or the laws of
    descent and distribution, or to an inter vivos trust with respect to which
    the Participant is treated as the owner under Sections 671 through 677 of
    the Code), pledged or sold prior to lapse of the restrictions applicable
    thereto.

<PAGE>   12
              (d)    DELIVERY OF SHARES UPON VESTING.  Upon expiration or
    earlier termination of the forfeiture period without a forfeiture and the
    satisfaction of or release from any other conditions prescribed by the
    Committee, or at such earlier time as provided under the provisions of
    Section 7.03, the restrictions applicable to the Restricted Shares shall
    lapse.  As promptly as administratively feasible thereafter, subject to the
    requirements of Section 10.05, the Company shall deliver to the Participant
    or, in case of the Participant's death, to the Participant's Beneficiary,
    one or more share certificates for the appropriate number of Company Common
    Shares, free of all such restrictions, except for any restrictions that may
    be imposed by law.

     7.02     TERMS OF RESTRICTED SHARES.

              (a)    FORFEITURE OF RESTRICTED SHARES.  Subject to Sections
    7.02(b) and 7.03, all Restricted Shares shall be forfeited and returned to
    the Company and all rights of the Participant with respect to such
    Restricted Shares shall terminate unless the Participant continues in the
    service of the Company or a Subsidiary as an employee until the expiration
    of the forfeiture period for such Restricted Shares and satisfies any and
    all other conditions set forth in the Award Agreement.  The Committee shall
    determine the forfeiture period (which may, but need not, lapse in
    installments) and any other terms and conditions applicable with respect to
    any Restricted Share Award provided that, unless otherwise authorized by
    the Board, such forfeiture period shall not be less than one year from the
    Date of Grant.

              (b)    WAIVER OF FORFEITURE PERIOD.  Notwithstanding anything
    contained in this Article VII to the contrary, the Committee may, in its
    sole discretion, waive the forfeiture period and any other conditions set
    forth in any Award Agreement under appropriate circumstances (including the
    death, disability or retirement of the Participant or a material change in
    circumstances arising after the date of an Award) and subject to such terms
    and conditions (including forfeiture of a proportionate number of the
    Restricted Shares) as the Committee shall deem appropriate, provided that
    the Participant shall at that time have completed at least one year of
    employment after the Date of Grant.  Waiver of the forfeiture period and
    any other conditions set forth in an Award Agreement prior to the
    Participant's completion of one year of employment after the Date of Grant
    may only be accomplished through action of the Board.

     7.03     CHANGE IN CONTROL.  In the event of a Change in Control, and
irrespective of whether or not the one year period following the date of the
Restricted Share Award required under the provisions of Section 7.02(a) has
been met, all restrictions applicable to the Restricted Shares Award shall
terminate fully and the Participant shall immediately have the right to the
delivery of share certificate or certificates for such shares in accordance
with Section 7.01(d).

                                  ARTICLE VIII
                               PERFORMANCE AWARDS

     8.01     PERFORMANCE AWARDS.

              (a)    AWARD PERIODS AND CALCULATIONS OF POTENTIAL INCENTIVE
    AMOUNTS.  The Committee may grant Performance Awards to Participants.  A
    Performance Award shall consist of the right to receive a payment (measured
    by the Fair Market Value of a specified number of Company Common Shares,
    increases in such Fair Market Value during the Award Period or a fixed cash
    amount) contingent upon the extent to which certain predetermined
    performance targets have been met during





                                      A-12
<PAGE>   13
    an Award Period.  Performance Awards may be made in conjunction with, or in
    addition to, Restricted Share Awards made under Article VII.  The Award
    Period shall be one or more calendar years as determined by the Committee.
    The Committee, in its discretion and under such terms as it deems
    appropriate, may permit newly eligible employees, such as those who are
    promoted or newly hired, to receive Performance Awards after an Award
    Period has commenced.

              (b)    PERFORMANCE TARGETS.  The performance targets may include
    specified levels of earnings per share, return on investment, return on
    shareholder equity and/or such other goals related to the performance of
    the Company or the performance of a Participant as may be established by
    the Committee in its discretion.  The performance targets established by
    the Committee may vary for different Award Periods and need not be the same
    for each Participant receiving a Performance Award in an Award Period.  The
    Committee, in its discretion, but only under extraordinary circumstances as
    determined by the Committee, may change any prior determination of
    performance targets for any Award Period at any time prior to the final
    determination of the Award when events or transactions occur to cause the
    performance targets to be an inappropriate measure of achievement.

              (c)    EARNING PERFORMANCE AWARDS.  The Committee at the Date of
    Grant shall prescribe a formula to determine the percentage of the
    Performance Award to be earned based upon the degree of attainment of
    performance targets.  In the event the minimum performance targets
    established by the Committee are not achieved, no payment shall be made to
    the Participant.  In the event the performance targets are fully achieved,
    100% of the Performance Award shall be paid to the Participant.  The
    Committee may provide for grants up to a maximum of 150% of Performance
    Awards for achievement exceeding performance targets.

              (d)    PAYMENT OF EARNED PERFORMANCE AWARDS.  Payments of earned
    Performance Awards shall be made in cash or Company Common Shares, or a
    combination of cash and Company Common Shares, in the discretion of the
    Committee.  Payment normally will be made as soon as is practicable
    following the end of an Award Period; provided, however, that the Committee
    may permit deferral of the payment of all or a portion of a Performance
    Award payable in cash upon the request of the Participant timely made in
    accordance with rules prescribed by the Committee.  Deferred amounts may
    generate earnings for the Participant under the conditions of a separate
    agreement providing for such as approved by the Committee and executed by
    the Participant.  The Committee, in its sole discretion, may also define
    such other conditions of payment of earned Performance Awards as it may
    deem desirable in carrying out the purposes of the Plan.

     8.02     TERMS OF PERFORMANCE AWARDS.

              (a)    TERMINATION OF EMPLOYMENT.  Unless otherwise provided
    below or in Section 8.03, in the case of a Participant's Termination of
    Employment prior to the end of an Award Period, the Participant will not
    have earned any Performance Awards.

              (b)    RETIREMENT.  If a Participant's Termination of Employment
    is because of retirement on a Normal Retirement Date or Other Retirement
    Date prior to the end of an Award Period, the Participant will not be paid
    any Performance Awards, unless the Committee, in its sole and exclusive
    discretion, determines that an Award should be paid.  In such a case, the
    Participant shall be entitled to receive a pro-rata portion of his or her
    Award as determined under Subsection (d).





                                      A-13
<PAGE>   14
              (c)    DEATH OR DISABILITY.  If a Participant's Termination of
    Employment is due to death or disability (as determined in the sole and
    exclusive discretion of the Committee) following at least one year of
    participation in any Award Period, but prior to the end of an Award Period,
    the Participant or the Participant's personal representative shall be
    entitled to receive a pro-rata share of his or her Award as determined
    under Subsection (d).

              (d)    PRO-RATA PAYMENT.  The amount of any payment made to a
    Participant whose employment is terminated by retirement, death or
    disability (under circumstances described in Subsections (b) and (c)) will
    be the amount determined by multiplying the amount of the Performance Award
    which would have been earned, determined at the end of the Award Period,
    had such employment not been terminated, by a fraction, the numerator of
    which is the number of whole months such Participant was employed during
    the Award Period, and the denominator of which is the total number of
    months of the Award Period.  Any such payment made to a Participant whose
    employment is terminated prior to the end of an Award Period under this
    Section 8.02 shall be made at the end of the respective Award Period,
    unless otherwise determined by the Committee in its sole discretion.  Any
    partial payment previously made or credited to a deferred account for the
    benefit of a Participant as provided under Section 8.01(d) of the Plan
    shall be subtracted from the amount otherwise determined as payable as
    provided in this Section.

              (e)    OTHER EVENTS.  Notwithstanding anything to the contrary in
    this Article VIII, the Committee may, in its sole and exclusive discretion,
    determine to pay all or any portion of a Performance Award to a Participant
    who has terminated employment prior to the end of an Award Period under
    certain circumstances (including the death, disability or retirement of the
    Participant or a material change in circumstances arising after the Date of
    Grant) and subject to such terms and conditions as the Committee shall deem
    appropriate, provided that the Participant shall have completed at his or
    her Termination of Employment at least one year of employment after the
    Date of Grant.  The Board may determine to pay all or a part of a
    Performance Award to a Participant who has completed less than one year of
    employment after the Date of Grant.

     8.03     CHANGE IN CONTROL.  In the event of a Change in Control, and
irrespective of whether or not the one year period following the date of the
Performance Award required under the provisions of Section 8.01 has been met,
all Performance Awards for all Award Periods shall immediately become fully
payable to all Participants and shall be paid to Participants within 30 days
after such Change in Control.

                                   ARTICLE IX
                                  OTHER AWARDS

     9.01     GRANT OF OTHER AWARDS.  Other Awards of cash, Awards of Company
Common Shares, or Awards valued in whole or in part by reference to, or
otherwise based on Company Common Shares, may be granted either alone or in
addition to or in conjunction with other Awards under the Plan.  Subject to the
provisions of the Plan, the Committee shall have sole and complete authority to
determine the persons to whom and the time or times at which such Awards shall
be made, the number of Company Common Shares to be granted pursuant to such
Awards, and all other conditions of the Awards.  Any such Award shall be
confirmed by an Award Agreement executed by the Committee and the Participant,
which Award Agreement shall contain such provisions as the Committee determines
to be necessary or appropriate to carry out the intent of this Plan with
respect to such Award.

<PAGE>   15
     9.02     TERMS OF OTHER AWARDS.  In addition to the terms and conditions
specified in the Award Agreement, Awards made pursuant to this Article IX shall
be subject to the following:

              (a)    Any Company Common Shares subject to Awards made under
    this Article IX may not be sold, assigned, transferred, pledged or
    otherwise encumbered prior to the date on which the shares are issued, or,
    if later, the date on which any applicable restriction, performance or
    deferral period lapses; and

              (b)    If specified by the Committee in the Award Agreement, the
    recipient of an Award under this Article IX shall be entitled to receive,
    currently or on a deferred basis, interest or dividends or dividend
    equivalents with respect to the Company Common Shares or other securities
    covered by the Award; and

              (c)    The Award Agreement with respect to any Award shall
    contain provisions dealing with the disposition of such Award in the event
    of a Termination of Employment prior to the exercise, realization or
    payment of such Award, whether such termination occurs because of
    retirement, disability, death or other reason, with such provisions to take
    account of the specific nature and purpose of the Award.

                                   ARTICLE X
             TERMS APPLICABLE TO ALL AWARDS GRANTED UNDER THE PLAN

    10.01     PLAN PROVISIONS CONTROL AWARD TERMS.  The terms of the Plan shall
govern all Awards granted under the Plan, and in no event shall the Committee
have the power to grant any Award under the Plan which is contrary to any of
the provisions of the Plan.  In the event any provision of any Award granted
under the Plan shall conflict with any term in the Plan as constituted on the
Date of Grant of such Award, the term in the Plan as constituted on the Date of
Grant of such Award shall control.  Except as provided in Section 10.03, the
terms of any Award granted under the Plan may not be changed after the Date of
Grant of such Award so as to materially decrease the value of the Award without
the express written approval of the holder.

    10.02     AWARD AGREEMENT.  No person shall have any rights under any Award
granted under the Plan unless and until the Company and the Participant to whom
such Award shall have been granted shall have executed and delivered an Award
Agreement or received any other Award acknowledgment authorized by the
Committee expressly granting the Award to such person and containing provisions
setting forth the terms of the Award.

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

    10.04     LIMITATION ON TRANSFER.  Except as provided in Section 7.01(c) in
the case of Restricted Shares, a Participant's rights and interest under the
Plan 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 personal representative) may
exercise rights under the Plan.





                                      A-15
<PAGE>   16
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.

    10.05     TAXES.  The Company shall be entitled, if the Committee deems it
necessary or desirable, to withhold (or secure payment from the Participant in
lieu of withholding) the amount of any withholding or other tax required by law
to be withheld or paid by the Company with respect to any amount payable and/or
shares issuable under such Participant's Award, or with respect to any income
recognized upon a disqualifying disposition of shares received pursuant to the
exercise of an Incentive Stock Option, and the Company may defer payment or
issuance of the cash or shares upon exercise or vesting of an Award unless
indemnified to its satisfaction against any liability for any such tax.  The
amount of such withholding or tax payment shall be determined by the Committee
and shall be payable by the Participant at the time of issuance or payment
(except as otherwise payable under Section 10.05(c)) in accordance with the
following rules:

              (a)    Unless otherwise provided by the Committee, with respect
    to Participants who are 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 such 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.

              (b)    With respect to Participants who are not subject to the
    provisions of Section 16(b) of the Exchange Act on the date on which the
    withholding requirements apply, the Participants 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 such Award;
    provided, however, that the payment of withholding requirements with
    respect to Restricted Share Awards shall be governed solely by the
    provisions of Section 7.01(d).

              (c)    If permitted under applicable Federal income tax laws, a
    Participant may elect to be taxed in the year in which an Award is made.
    If the Participant makes such an election, the Participant shall promptly
    notify the Company in writing and shall provide the Company with a copy of
    the executed election form as filed with the Internal Revenue Service by no
    later than thirty days from the Date of the Grant.  Promptly following such
    notification, the Participant shall pay directly to the Company the cash
    amount determined by the Company to be sufficient to satisfy applicable
    federal, state or local withholding tax requirements.

              (d)    The Committee shall have the discretion as to any Award,
    to cause the Company to pay to tax authorities for the benefit of any
    Participant, or to reimburse such Participant for the individual taxes
    which are due on the grant, exercise or vesting of any share Award, or the
    lapse of any restriction on any share Award (whether by reason of a
    Participant's filing of an election under Section 83(b) of the Code or
    otherwise), including, but not limited to, federal income tax, state income
    tax, local income tax and excise tax under Section 4999 of the Code, as
    well as for any such taxes as may be imposed upon such tax payment or
    reimbursement.

    10.06     SURRENDER OF AWARDS.  Any Award granted under the Plan may be
surrendered to the Company for cancellation on such terms as the Committee and
the holder approve.

    10.07     ADJUSTMENTS TO REFLECT CAPITAL CHANGES.

              (a)    RECAPITALIZATION.  The number and kind of shares subject
    to outstanding Awards, the Purchase Price or Exercise Price for such
    shares, and the number and kind of shares available for Awards subsequently
    granted under the Plan 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 the Plan or the Awards granted under the Plan.  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, each Participant shall, at no additional cost, be
    entitled upon any exercise of an Option or receipt of other Award to
    receive (subject to any required action by shareholders), in lieu of the
    number of Company Common Shares receivable or exercisable pursuant to such
    Award, the number and class of shares or other securities to which such
    Participant would have been entitled pursuant to the terms of the Merger
    if, at the time of the Merger, such Participant had been the holder of
    record of a number of shares equal to the number of shares receivable or
    exercisable pursuant to such Award.  Comparable rights shall accrue to each
    Participant in the event of successive Mergers of the character described
    above.

              (c)    OPTIONS TO PURCHASE SHARES OR STOCK OF ACQUIRED COMPANIES.
    After any Merger in which the Company or a Subsidiary shall be a surviving
    corporation, the Committee may grant substituted options under the
    provisions of the Plan, pursuant to Section 425 of the Code, replacing old
    options granted under a plan of another party to the Merger whose shares or
    stock subject to the old options may no longer be issued following the
    Merger.  The foregoing adjustments and manner of application of the
    foregoing provisions shall be determined by the Committee in its sole
    discretion.  Any such adjustments may provide for the elimination of any
    fractional shares which might otherwise become subject to any Options.

    10.08     NO RIGHT TO EMPLOYMENT.  No employee or other person shall have
any claim of right to be granted an Award under this Plan.  Neither the Plan
nor any action taken hereunder shall be construed as giving any employee any
right to be retained in the employ of the Company or any of its Subsidiaries.

    10.09     AWARDS NOT INCLUDABLE FOR BENEFIT PURPOSES.  Payments received by
a Participant pursuant to the provisions of the Plan 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 or determined by the Board.

    10.10     GOVERNING LAW.  All determinations made and actions taken
pursuant to the Plan shall be governed by the laws of the State of Ohio and
construed in accordance therewith.

    10.11     NO STRICT CONSTRUCTION.  No rule of strict construction shall be
implied against the Company, the Committee, or any other person in the
interpretation of any of the terms of the Plan, any Award granted under the
Plan or any rule or procedure established by the Committee.





                                      A-17
<PAGE>   18
    10.12     COMPLIANCE WITH RULE 16B-3.  It is intended that the Plan be
applied and administered in compliance with Rule 16b-3.  If any provision of
the Plan 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 16b-3, as determined by the Committee.  The Board is
authorized to amend the Plan and to make any such modifications to Award
Agreements to comply with Rule 16b-3, as it may be amended from time to time,
and to make any other such amendments or modifications as it deems necessary or
appropriate to better accomplish the purposes of the Plan in light of any
amendments made to Rule 16b-3.

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

    10.14     SEVERABILITY.  Whenever possible, each provision in the Plan and
every Award at any time granted under the Plan shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of the Plan or any Award at any time granted under the Plan shall be held to be
prohibited by or invalid under applicable law, then (a) such provision shall be
deemed amended to accomplish the objectives of the provision as originally
written to the fullest extent permitted by law and (b) all other provisions of
the Plan and every other Award at any time granted under the Plan shall remain
in full force and effect.

    10.15     AMENDMENT AND TERMINATION.

              (a)    AMENDMENT.  The Board shall have complete power and
    authority to amend the Plan at any time and to add any other share award or
    other incentive compensation programs to the Plan as it deems necessary or
    appropriate and no approval by the shareholders of the Company or by any
    other person, committee or entity of any kind shall be required to make any
    amendment; provided, however, that the Board shall not, without the
    requisite affirmative approval of shareholders of the Company, make any
    amendment which requires shareholder approval under Rule 16b-3 or the Code,
    unless such compliance is no longer mandatory under Rule 16b-3, the Code or
    under any other applicable law or rule of any stock exchange which lists
    Company Common Shares or Company Voting Securities.  No termination or
    amendment of the Plan may, without the consent of the Participant to whom
    any Award shall theretofore have been granted under the Plan, adversely
    affect the right of such individual under such Award.  For the purposes of
    this section, an amendment to the Plan shall be deemed to have the
    affirmative approval of the shareholders of the Company if such amendment
    shall have been submitted for a vote by the shareholders at a duly called
    and constituted meeting of such shareholders at which a quorum is present
    and a majority of the votes cast with respect to such amendment at such
    meeting shall have been cast in favor of such amendment.

              (b)    TERMINATION.  The Board shall have the right and the power
    to terminate the Plan at any time.  No Award shall be granted under the
    Plan after the termination of the Plan, but the termination of the Plan
    shall not have any other effect and any Award outstanding at the time of
    the termination of the Plan may be exercised after termination of the Plan
    at any time prior to the expiration date of such Award to the same extent
    such Award would have been exercisable had the Plan not terminated.

    10.16     STATUS OF PRIOR PLANS.  On February 25, 1991, the date when the
Board approved this Plan, the Company also had in effect other valid long-term
incentive plans for the benefit of officers and key employees, including the
Medusa Corporation 1988 Restricted Stock Award Plan, the Medusa Corporation
1988 Stock Option Plan and the Medusa Corporation 1988 Stock Appreciation
Rights Plan (the "Existing Plans").  At the time of its approval of this Plan
the Board also indicated its intent that the Existing Plans should survive the
approval of this Plan.

              SENIOR EXECUTIVE OFFICER RESTRICTED SHARE AGREEMENT
           UNDER THE MEDUSA CORPORATION 1991 LONG-TERM INCENTIVE PLAN
                         BETWEEN MEDUSA CORPORATION AND
                             [Fill-in: Participant]

                            DATED AS OF MAY 8, 1995


In recognition of the valued services performed by [Fill-in: Participant] (the
"Participant") for Medusa Corporation and its subsidiaries and as an incentive
for continued employment, Medusa Corporation, (the "Corporation"), through the
Organization and Compensation Committee of its Board of Directors (the
"Committee"), has determined to award to the Participant [Fill-in: Total
Shares] restricted shares (the "Restricted Shares") under the terms of the 1991
Long-Term Incentive Plan of Medusa Corporation (the "Plan") (a copy of which is
attached hereto and made a part hereof).

As a condition to such award and pursuant to Section 7.01(a) of the Plan, the
Corporation and the Participant hereby enter into this Restricted Share
Agreement with respect to the award of Performance Restricted Shares (as
defined below), and the award of SERP-Equivalent Restricted Shares (as defined
below), and agree to the terms and conditions set forth hereafter.

 1.      DEFINITIONS.

         For purposes of this Agreement, and for purposes of interpreting the
         terms of the Plan, the following terms shall have the following
         meanings:

         a.   "CEMENT INDUSTRY PEER GROUP INDEX" shall mean the index which
              reflects the cumulative total return (the fair market value plus
              the dividends and distributions) for the Restriction Period of
              the following cement companies, Giant Cement Holding, Inc.,
              Lafarge Corporation, Lone Star Industries, Puerto Rican Cement
              Co., Inc., Southdown Inc. and Texas Industries, weighted on the
              basis of the market capitalization of such cement companies.

         b.   "CHANGE IN CONTROL" shall have the meaning set forth in Section
              2.07 of the Plan.

         c.   "FAIR MARKET VALUE" shall mean "Fair Market Value" as defined in
              Section 2.16 of the Plan.

         d.   "GRANT PRICE" shall mean $24.375 per share which is the average
              of the high and low quoted sales prices of the Common Shares of
              Medusa Corporation ("Medusa Shares"), as reported in the New York
              Stock Exchange Composite Transactions ("Average Price") on May 8,
              1995 (the "Start Date").  In the event that there is an increase
              in the number of issued Medusa Shares by reason of stock
              dividends distributions, recapitalizations, or split-ups, the
              Grant Price shall promptly after such

                                     -1-
<PAGE>   2
              event be decreased in proportion to such increase in issued
              Medusa Shares that occurred as a result of such event.

              Conversely, in case the issued Medusa Shares shall be combined
              into a smaller number of Medusa Shares, the Grant Price shall be
              promptly after such event increased in proportion to such
              decrease in issued Medusa Shares that has occurred as a result of
              such event.  In the event of any merger, consolidation,
              reorganization, liquidation in part or in whole, spinoff,
              spinout, or extraordinary distribution or dividend on Medusa
              Shares whether in cash, debt obligations of the Corporation or
              other personal property of any kind, the Committee may make such
              adjustment in the Grant Price as the Committee in its reasonable
              discretion deems appropriate.

         e.   "MEDUSA TOTAL RETURN" shall mean, with respect to Performance
              Restricted Shares, the total return on the Medusa Shares at any
              time during the five year period commencing on the Start Date and
              ending on the final Test Date and shall be calculated as follows:

                     Medusa Total Return = B/A-1

                          A       =        the Grant Price

                          B       =        C x D

                          C       =        the Average Price on the Test Date

                          D       =        The number of Medusa Shares that
                                           would have been owned on the Test
                                           Date assuming one such Medusa Share
                                           had been owned on the Start Date and
                                           all dividends and distributions,
                                           whether in cash, in kind, or in debt
                                           or equity securities of the
                                           Corporation, subsequent to the Start
                                           Date had been reinvested in Medusa
                                           Shares.

                          For the purpose of calculating "D":

                          (a)     the amount of each dividend shall be assumed
                                  to have been reinvested by acquiring Medusa
                                  Shares at their average price on the relevant
                                  ex-dividend date;

                          (b)     the amount of a dividend paid in marketable
                                  securities (such as spin-offs of subsidiary
                                  stock) shall be deemed to be the average
                                  price of such securities in the relevant
                                  market therefor on the relevant ex-dividend
                                  date;

                          (c)     the amount of a dividend paid other than in
                                  cash or marketable securities, shall be
                                  deemed to be the fair market value of the
                                  asset transferred as of the relevant
                                  ex-dividend date;





                                     -2-
<PAGE>   3
                          (d)     no allowance shall be made for tax or
                                  transaction costs.

         f.   "PERFORMANCE LAPSE PERCENTAGE" (as used in Section 3 below) is
              the percentage of the Performance Restricted Shares for which the
              Performance Restrictions lapse, which percentage is in proportion
              to the percentage (in 1% increments) occurring within a range
              from 101% to 110% by which the Medusa Total Return exceeds the
              cumulative total return of the Cement Industry Peer Group.  In
              other words, if the Medusa Total Return exceeds the peer group by
              only 101%, then the Performance Restrictions shall lapse on only
              10% of Performance Restricted Shares tested on that Test Date (a
              "Partial Lapse"), and, if the exceedance is 110% or higher, the
              Performance Restrictions shall lapse on all of the Performance
              Restricted Shares tested on that Test Date.  In the event of a
              Partial Lapse, the Performance Restricted Shares which were
              tested and for which the Performance Restrictions did not lapse,
              shall be retested on subsequent Test Dates (as applicable) during
              the Restriction Period.

         g.   "PERFORMANCE RESTRICTED SHARES" shall mean that portion of the
              Restricted Shares awarded by the Committee to the Participant
              which are performance-restricted.

         h.   "PERMANENT TOTAL DISABILITY", as provided in Section 2.33 of the
              Plan, shall be determined in each case, by the Committee in its
              sole discretion.

         i.   "RESTRICTION PERIOD" shall mean a period commencing on the date
              of the award on May 8, 1995, the Start Date, and ending five
              years later on May 8, 2000.  (Except in the case of
              SERP-Equivalent Restricted Shares which shall vest on May 8, 2000
              and shall remain Restricted so long thereafter, as the
              Participant is an employee of the Corporation.)

         j.   "RETIREMENT" shall have the following meaning:

                     (i)  for the purpose of the Performance Restricted Shares,
              "Retirement", for Senior Executive Officers, shall mean "Normal
              Retirement Date" as defined in Section 2.21 of the Plan, which is
              retirement at any date; (it is not limited to retirement at age
              65; by action of the Board on May 9, 1994);

                     (ii)  for the purpose of the SERP-Equivalent Restricted
              Shares, "Retirement" shall mean age 62; in such cases "Normal
              Retirement Date" shall be the first day of the month following a
              Participant attaining age 62.

         k.   "SENIOR EXECUTIVE" shall mean the Chairman or the President of
              the Company.

         l.   "SERP-EQUIVALENT RESTRICTED SHARES" shall mean that portion of
              the Restricted Shares awarded by the Committee to the Participant
              which are time-restricted.





                                     -3-
<PAGE>   4
         m.   "TEST DATE" shall mean, with respect to one-fifth of the
              Performance Restricted Shares, the following five dates, May 9,
              1996, May 8, 1997, May 8, 1998, May 8, 1999 and May 8, 2000 or
              the next business day thereafter if the New York Stock Exchange
              is not open on such date, or the day on which a Change in Control
              occurs.

 2.      AWARD OF PERFORMANCE RESTRICTED SHARES.

         Pursuant to the provisions of the Plan and this Agreement and by the
         authority of the Committee:

         a.   The Corporation hereby awards [Fill-in: PRS Shares] Performance
              Restricted Shares to the Participant.

         b.   When the Restrictions on the Performance Restricted Shares lapse
              for any reason, the Corporation shall also pay to the Participant
              at the time when the Restrictions on the Performance Restricted
              Shares lapse, a separate cash amount equal to:

              (1)    the federal, state and local income tax and golden
                     parachute excise tax (if any) payable with respect to the
                     lapse of the Performance Restrictions (as defined below),
                     divided by

              (2)    one (1) minus the total effective federal, state and local
                     income and excise tax rate applicable as a result of the
                     lapse of the Performance Restrictions.

 3.      PERFORMANCE RESTRICTED SHARE; RESTRICTIONS AND RIGHTS.

         a.   During the Restriction Period, the Performance Restricted Shares
              are subject to forfeiture and may not be sold, transferred,
              assigned or pledged (the "Performance Restrictions").  The
              Performance Restrictions shall automatically lapse, based upon
              the actual Performance Lapse Percentage calculated as of the
              following Test Dates:

              (1)    With respect to up to one-fifth of the Performance
                     Restricted Shares hereunder, if on the Test Date for the
                     period from May 8, 1995 to May 9, 1996, both of the
                     following tests shall be met: (a) the Fair Market Value
                     shall exceed the Grant Price, and (b) the Medusa Total
                     Return shall exceed the cumulative total return of the
                     Cement Industry Peer Group Index for the period from May
                     8, 1995 to May 9, 1996.

              (2)    With respect to up to two-fifths of the Performance
                     Restricted Shares hereunder, if on the Test Date for the
                     period from May 8, 1995 to May 8, 1997, both of the
                     following tests shall be met: (a) the Fair Market Value
                     shall exceed the Grant Price, and (b) the Medusa Total
                     Return shall exceed the cumulative total return of the
                     Cement Industry Peer Group Index for the period from May
                     8, 1995 to May 8, 1997.

 4.      AWARD OF SERP-EQUIVALENT SHARES.

         Pursuant to the provisions of the Plan, as authorized by the Board on
         March 27, 1995, this Agreement and by the authority delegated by the
         Board to the Committee, the Corporation hereby awards [Fill-in: SERP
         Shares] SERP-Equivalent Restricted Shares to the Participant, which is
         the number of Restricted Shares actuarially determined to provide a
         benefit to the Participant which is supplemental to the benefit
         provided under the Medusa Corporation Pension Plan for Certain Covered
         Employees, assuming fifteen





                                     -5-

         (15) years service, with Retirement (at age 62), and reflecting the
         Participant's base compensation and compensation under the Corporation
         Annual Incentive Plan from date of hire to the Participant's Normal
         Retirement Date, averaged over the highest five consecutive calendar
         years during the last ten years prior to Retirement.

 5.      SERP-EQUIVALENT RESTRICTED SHARES; RESTRICTIONS AND RIGHTS.

         a.   VESTING.

              (1)    Unless the Committee waives the vesting requirements, the
                     SERP-Equivalent Restricted Shares are forfeitable if the
                     Participant ceases to remain an employee of the
                     Corporation for five years, namely until May 8, 2000.

              (2)    Provided, nonetheless, that the SERP-Equivalent Restricted
                     Shares shall vest upon the Participant attaining age 62.

              (4)    The SERP-Equivalent Shares shall also vest in the event of
                     the Participant's death, a Change of Control or in the
                     event that the Committee determines that the Participant
                     has experienced a Permanent Total Disability.

              (5)    The SERP-Equivalent Shares may also vest as may otherwise
                     be provided under the terms of the Plan.

              If the Participant leaves the employ of the Corporation prior to
              the vesting of the SERP-Equivalent Shares by reason of the
              operation of clauses (1) through (5) of the foregoing subsection,
              the SERP-Equivalent Shares shall be forfeited and the Participant
              shall be required to return all applicable SERP-Equivalent
              Restricted Share certificates to the Corporation.

         b.   POST-VESTING RESTRICTIONS.

              (1)    During the post-vesting Restriction Period, the
                     SERP-Equivalent Restricted Shares may not be sold,
                     transferred, assigned or pledged.  Such restrictions shall
                     lapse when the Participant is no longer an employee of the
                     Corporation (the "SERP- Equivalent Restrictions").

              (2)    The presence of post-vesting restrictions shall not
                     prevent the Participant from transferring a sufficient
                     number of SERP- Equivalent Restricted Shares for the
                     purpose of generating the cash required to pay the taxes
                     due upon vesting, at which time the Corporation may, but
                     is not required to, assume the Participant's tax
                     obligation in return for the surrender of the number of
                     SERP-Equivalent Restricted Shares which is equivalent to
                     the Fair Market Value of such tax obligation.

<PAGE>   7
              (3)    Upon the request of a Participant who is employed by the
                     Corporation, the Committee may at any time exercise its
                     authority to allow the transfer of any or all
                     SERP-Equivalent Restricted Shares in order for the
                     Participant to diversify his or her retirement asset
                     portfolio.

              (4)    The SERP-Equivalent Restrictions also lapse in the event
                     of the Participant's death, a Change of Control or in the
                     event that the Committee determines that the Participant
                     has experienced a Permanent Total Disability.

              (5)    The SERP-Equivalent Restrictions may also lapse as may
                     otherwise be provided under the terms of the Plan.

              If the Participant leaves the employ of the Corporation prior to
              the Participant's Normal Retirement Date, and prior to the
              occurrence of any of the events described above in clause 4 of
              the foregoing subsection, then the restrictions on the SERP-
              Equivalent Shares shall, nonetheless, not lapse until the
              Participant's Normal Retirement Date.

         c.   During the Restriction Period, the Participant shall be entitled
              to all other rights as a shareholder of the Corporation,
              including the right to vote the SERP-Equivalent Restricted Shares
              and receive dividends and other distributions thereon, with share
              dividends subject however to the same restrictions as the
              SERP-Equivalent Restricted Shares.

 6.      SHARE CERTIFICATES.

         Each share certificate evidencing an award of Restricted Shares shall
         be registered in the name of the Participant, and shall bear an
         appropriate legend referring to the terms, conditions and restrictions
         applicable to such award substantially in the following form (the
         "Legend"):

              "The transferability of this certificate and the shares
              represented hereby are subject to the terms and conditions
              (including forfeiture) of the 1991 Long-Term Incentive Plan of
              Medusa Corporation and an Agreement entered into between the
              registered owner and Medusa Corporation.  Copies of such Plan and
              Agreement are on file and may be obtained upon request without
              charge from the offices of the Secretary of Medusa Corporation,
              P.O. Box 5668, Cleveland, Ohio 44101."

 7.      TERMINATION OF EMPLOYMENT.

         Except as provided in Sections 3 and 5 of this Restricted Share
         Agreement and Section 7.02(a) of the Plan, the termination of
         Participant's employment during the Restriction Period (or prior to
         vesting, in the case of the SERP-Equivalent Restricted Shares) shall
         result in the forfeiture of all Restricted Shares as to which the
         Performance Restrictions have not lapsed or the SERP- Equivalent
         Shares which have not vested, and the Participant shall be required to
         return all applicable share certificates to the Corporation.

              Commission, of any stock exchange upon which the Restricted

              other law.

 9.      NO COVENANT OF EMPLOYMENT.

         Neither the execution and delivery hereof nor the granting of any
         award evidenced hereby shall constitute, or be evidence of, any
         agreement or understanding, express or implied, on the part of the
         Corporation or its subsidiaries to employ the Participant for any
         specific period.

10.      INTERPRETATION AND ADMINISTRATION OF PLAN AND AGREEMENT.

         a.   In the event of any conflict between the terms herein and those
              of the Plan, the provisions of the Plan shall prevail.

         b.   The Committee shall have full authority and discretion, subject
              only to the terms of the Plan, to decide all matters relating to
              the interpretation or administration of the Plan and this
              Agreement thereunder, and all such action by the Committee shall
              be final, conclusive, and binding upon the Corporation and the
              Participant.  The Committee shall have full authority and
              discretion to modify at any time the vesting and/or the
              Restriction Period (as well as any schedule of installments for
              the lapse thereof), the Performance Restrictions or the
              SERP-Equivalent Restrictions, the other terms and conditions of
              this Agreement, the Legend and any other instrument evidencing
              this award, provided that no such modification shall increase the
              benefit under such award beyond that which the Committee could
              have originally granted at the time of the award, or shall impair
              the rights of the Participant under such award except in
              accordance with the Plan, or any applicable agreement or
              applicable law, or with the consent of the Participant.

         This Restricted Share Agreement is deemed to be issued in, the award
         evidenced hereby is deemed to be granted in, and both shall be
         governed by the laws of the State of Ohio.

         those contained herein.

         requirements of the Securities and Exchange Commission, any stock
         exchange upon which the Restricted Shares are then listed and any
         applicable federal or state securities law, and the Committee may
         cause a legend or legends to be put on any such certificates to make
         appropriate reference to such restrictions.

         The Committee may adopt rules which provide that the certificates
         evidencing the Restricted Shares may be held in custody by a bank or
         other institution, or that the Corporation may itself hold the
         Restricted Shares in custody until the restrictions thereon shall have
         lapsed and may require, as a condition of any award, that the
         Participant shall have delivered a stock power endorsed in blank

         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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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

                 forth above.  Any such notice shall be deemed to be duly given

                      [  Medusa Corporation Letterhead  ]
                                                               February 15, 1996

Medusa Corporation
Lee and Monticello Boulevards
Cleveland Heights, Ohio  44118

Gentlemen,

I am Vice President, Secretary and General Counsel of Medusa Corporation (the
"Company").  This opinion is furnished as an Exhibit to Registration Statement
Amendment on Form S-8 (the "Amended Registration Statement"), under the
Company's 1991 Long-Term Incentive Plan (the "Plan"), filed by the Company with
the Securities and Exchange Commission, for the purpose of registering the
Company's Common Shares, without par value (the "Common Shares"), under the
Securities and Exchange Act of 1934, as amended.

On May 6, 1991, the shareholders of the Company authorized the issuance of up
to 500,000 Common Shares to officers and key employees of the Company under the
Plan, as contained in (the original) Registration Statement on Form S-8 dated
March 4, 1992.  This Amended Registration Statement, for the increase in
issuance authority of up to an additional 1,000,000 Common Shares, is required
as a result of the October 7, 1993 stock distribution at the rate of one
additional Common Share for each two Common Shares held (which added 250,000
Common Shares to the above 500,000 Common Share authority); and the
shareholders' approval on May 9, 1994 of an amendment to the Plan approving an
additional 750,000 Common Share issuance authority;

In connection with rendering this opinion, I have examined the Articles of
Incorporation of the Company, corporate proceedings of the Company, and such
other documents and such questions of law as I deemed necessary or appropriate.

Based on the foregoing, I am pleased to advise you that in my opinion:

         (i)  the Company has been duly incorporated and is a lawfully and
validly existing corporation under the laws of the State of Ohio; and

         (ii)  the Articles of Incorporation of the Company, amended as of May
9, 1994, authorizes the issuance of up to 50,000,000 Common Shares, of which
16,362,557 Common Shares are issued and outstanding on the date of this
opinion, and the issued and outstanding Common Shares were validly issued and
are fully paid and nonassessable.

I hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement.

                                     Sincerely,

                                     /s/ John P. Siegfried
                                     John P. Siegfried
