                          REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (this "Agreement"), dated as of
________________, 2005, is entered into by and among Oglebay Norton Company, an
Ohio corporation (the "Company") and the holders of Subordinated Notes (as
defined herein) signatories hereto (each, a "Noteholder" and, collectively, the
"Noteholders") and certain third party accredited investors signatory hereto
(the "Third Party Investors" and, together with the Noteholders, the
"Subscribers").

                             PRELIMINARY STATEMENTS

A. The Company and the Subscribers are parties to that certain Commitment
Agreement, dated as of February 23, 2004 (as heretofore amended, the "Commitment
Agreement"), pursuant to which, among other things, the Subscribers agreed to
purchase up to $85 million of Preferred Shares (as defined in the Commitment
Agreement) of the Company, the proceeds of which are to be used to fund the
redemption of the Company's outstanding Senior Secured Notes due 2008 (the
"Senior Notes") subsequent to the reinstatement of the Senior Notes pursuant to
the Second Amended Joint Plan of Reorganization of the Company and its
subsidiaries dated July 30, 2004 (the "Amended Plan") in connection with the
Chapter 11 Case of the Company and its subsidiaries.

B. As contemplated by the Commitment Agreement, the Company filed a registration
statement on Form S-1 (the "Primary Registration Statement") relating to the
offering of Preferred Shares to holders of Subordinated Notes (the "Offering").
The Company amended the Primary Registration Statement in order to limit the
Offering to holders of Subordinated Notes other than the Noteholders in an
amount equal to their pro rata portion of $53,711,200 of Preferred Shares. The
Primary Registration Statement was declared effective by the Securities and
Exchange Commission (the "SEC") on December 27, 2004 and pursuant to the
Offering, which expired on January 25, 2005, holders of Subordinated Notes have
subscribed for an aggregate of $_____________ million of Preferred Shares.
Accordingly, pursuant to, and subject to the terms and conditions of the
Commitment Agreement, the Subscribers have agreed to purchase in the aggregate
of $____________ million of Preferred Shares consisting of (i) of $26,288,800 of
Preferred Shares representing the Noteholders' Basic Commitment Amount (as
defined in the Commitment Agreement), (ii) $__________ million of Preferred
Shares pursuant to the Subscribers' Standby Commitment (as defined in the
Commitment Agreement) and (iii) $5 million of additional Preferred Shares.

C. Pursuant to the Commitment Agreement, the obligations of the Subscribers to
purchase the Preferred Shares is conditional upon, among other things, the
Company having executed and delivered to the Subscribers this Registration
Rights Agreement to provide the Subscribers certain rights as set forth herein.

D. Defined terms used but not otherwise defined herein shall have the meanings
ascribed to them in the Commitment Agreement or in the Amended Plan.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in this Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

SECTION 1. Registration of Resale of the Preferred Shares; Compliance with the
Securities Act.

1.1 Registration Procedures and Expenses. The Company shall:

         (a) use its reasonable best efforts to cause the Registration Statement
on Form S-1 (the "Registration Statement") filed by the Company with the SEC
pursuant to the Securities Act of 1933, as amended (the "Securities Act") on
January ___, 2005 with respect to the resale of the Preferred Shares (including
the shares of Common Stock issuable upon conversion thereof, collectively
together with the Preferred Shares, the "Shares") by the Subscribers from time
to time in accordance with the methods of distribution set forth in the
Registration Statement to be declared effective by the SEC as soon as
practicable;

         (b) prepare and file with the SEC such amendments to the Registration
Statement and such supplements to the prospectus used in connection therewith as
may be necessary in the opinion of the Company to keep the Registration
Statement effective until the earlier of (i) twenty-four months after the
effective date of the Registration Statement, (ii) such shorter period that will
terminate when all the Shares covered by the Registration Statement have been
sold pursuant thereto and (iii) the date on which the Shares may be resold by
the Subscribers without registration by reason of Rule 144(k) under the
Securities Act or any other rule of similar effect;

         (c) furnish to each Subscriber (and to each underwriter, if any, of
such Shares), at least one conformed copy of the Registration Statement and any
post-effective amendment thereto, including financial statements (but excluding
all schedules, all documents incorporated or deemed incorporated therein by
reference and all exhibits);

         (d) furnish to the Subscribers with respect to the Shares registered
under the Registration Statement (and to each underwriter, if any, of such
Shares) such reasonable number of copies of prospectuses and any amendments or
supplements thereto as each Subscriber may reasonably request, in order to
facilitate the public sale or other disposition of all or any of the Shares by
the Subscribers; provided, however, that the obligation of the Company to
deliver copies of prospectuses to any Subscriber shall be subject to the receipt
by the Company of reasonable assurances from the Subscriber (which assurances
are deemed received upon execution of this Agreement by such Subscriber) that
the Subscriber will comply with the applicable provisions of the Securities Act
and of such other securities or blue sky laws as may be applicable in connection
with any use of such prospectuses;

         (e) file documents required of the Company for blue sky clearance in
jurisdictions within the United States as the Subscribers reasonably request in
writing; provided, however, that the Company shall not be required to qualify
generally to do business or take any action which would subject it to general
service of process or taxation in any jurisdiction which it is not so subject;
and

                                      -2-
<PAGE>
         (f) bear all expenses in connection with the preparation and filing of
the Registration Statement and the procedures in paragraphs (a) through (e) of
this Section 1.1 and the registration of the Shares pursuant to the Registration
Statement, other than fees and expenses, if any, of counsel or other advisers to
the Subscribers or underwriting discounts, brokerage fees, commissions and stock
transfer taxes incurred by, or applicable to, any Subscriber.

1.2 Transfer of Shares After Registration.

         (a) Each Subscriber agrees that it will not effect any disposition of
the Shares that would constitute a sale within the meaning of the Securities
Act, except as contemplated in the Registration Statement referred to in Section
1.1, and that it will promptly notify the Company of any changes in the
information set forth in the Registration Statement regarding the Subscriber or
its plan of distribution. In addition, the Company may require any Subscriber
promptly to furnish in writing to the Company such information regarding the
intended methods of distribution of the Shares as the Company may from time to
time reasonably request and such other information as may be legally required in
connection with such registration including, without limitation, all such
information as may be requested by the SEC or the National Association of
Securities Dealers, Inc. The Company may refuse to proceed with the registration
of such Subscriber's Shares if such Subscriber unreasonably fails to furnish
such information within a reasonable time after receiving such request. The
Company, upon the reasonable request of a Subscriber, will meet with the
Subscriber or a representative thereof at the Company's headquarters to discuss
information relevant for disclosure in the Registration Statement subject to
appropriate confidentiality limitations.

         (b) Each Subscriber hereby covenants with the Company not to make any
sale of the Shares without satisfying the prospectus delivery requirement under
the Securities Act. Each Subscriber further agrees that, in the case of Shares
transferred through a broker, such Shares are not transferable on the books of
the Company unless the certificate submitted to the transfer agent evidencing
the Shares is accompanied by a separate notice of transfer in the form of
Appendix I hereto, executed by a broker designated by the Subscriber. Each
Subscriber acknowledges that there may occasionally be times when the Company
must suspend the use of the prospectus forming a part of the Registration
Statement until such time as a supplement to the prospectus has been filed with
the SEC or an amendment to the Registration Statement has been filed by the
Company and declared effective by the SEC, or until such time as the Company has
filed an appropriate report with the SEC pursuant to the Securities Exchange Act
of 1934 (the "Exchange Act"). The Subscriber hereby covenants that it will not
sell any Shares pursuant to said prospectus during the period commencing at the
time at which the Company gives the Subscriber written notice of the suspension
of the use of said prospectus and ending at the time the Company gives the
Subscriber written notice that the Subscriber may thereafter effect sales
pursuant to said prospectus. Each Subscriber further covenants to notify the
Company promptly of the sale of any of its Shares.

1.3 Indemnification. For the purpose of this Section 1.3, the term "Registration
Statement" shall include any final prospectus, exhibit, supplement or amendment
included in or relating to the Registration Statement referred to in Section
1.1.

                                      -3-
<PAGE>

         (a) The Company agrees to indemnify and hold harmless each of the
Subscribers, their respective officers, directors, employees and agents and each
person, if any, who controls any Subscriber within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act (collectively, the
"Subscriber Indemnified Persons"), against any losses, claims, damages,
liabilities or expenses, joint or several, to which such Subscriber or
Subscriber Indemnified Person may become subject, under the Securities Act, the
Exchange Act, or any other federal or state statutory law or regulation, or at
common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of the Company), insofar as such
losses, claims, damages, liabilities or expenses (or actions in respect thereof
as contemplated below) arise out of or are based upon any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, including the prospectus, financial statements and schedules, and all
other documents filed as a part thereof, as amended at the time of effectiveness
of the Registration Statement, including any information deemed to be a part
thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A
of the Rules and Regulations, or the prospectus, in the form first filed with
the Commission pursuant to Rule 424(b) of the Regulations, or filed as part of
the Registration Statement at the time of effectiveness if no Rule 424(b) filing
is required (the "Prospectus"), or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state in any of
them a material fact required to be stated therein or necessary to make the
statements in any of them, in light of the circumstances under which they were
made, not misleading, and will reimburse each Subscriber or such Subscriber
Indemnified Person for any legal and other expenses as such expenses are
reasonably incurred by such Subscriber or such Subscriber Indemnified Person in
connection with investigating, defending, settling, compromising or paying any
such loss, claim, damage, liability, expense or action; provided, however, that
the Company will not be liable in any such case to the extent that any such
loss, claim, damage, liability or expense arises out of or is based upon (i) an
untrue statement or alleged untrue statement or omission or alleged omission
made in the Registration Statement, the Prospectus or any amendment or
supplement thereto in reliance upon and in conformity with written information
furnished to the Company by or on behalf of any Subscriber expressly for use
therein, or (ii) the failure of any Subscriber to comply with the covenants and
agreements contained in Section 1.3 hereof respecting sale of the Shares, or
(iii) any statement or omission in any Prospectus that is corrected in any
subsequent Prospectus that was delivered to any Subscriber prior to the
pertinent sale or sales by the Subscriber.

         (b) Each Subscriber will severally and not jointly indemnify and hold
harmless the Company, each of its directors, officers, employees and agents and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act (collectively, the
"Company Indemnified Persons"), against any losses, claims, damages, liabilities
or expenses to which the Company or such Company Indemnified Person may become
subject, under the Securities Act, the Exchange Act, or any other federal or
state statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of such Subscriber) insofar as such losses, claims, damages, liabilities
or expenses (or actions in respect thereof as contemplated below) arise out of
or are based upon (i) any failure by such Subscriber to comply with the
covenants and agreements contained in Section 1.2 hereof respecting the sale of
the Shares or (ii) any untrue or alleged untrue statement of any material fact
contained in the Registration Statement, the Prospectus, or any amendment or
supplement thereto, or arise out of

                                      -4-
<PAGE>
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in the
Registration Statement, the Prospectus, or any amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the
Company by or on behalf of such Subscriber expressly for use therein, and will
reimburse the Company or such Company Indemnified Person for any legal and other
expense reasonably incurred by the Company or such Company Indemnified Person in
connection with investigating, defending, settling, compromising or paying any
such loss, claim, damage, liability, expense or action.

         (c) Promptly after receipt by an indemnified party under this Section
1.3 of notice of the threat or commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party under this Section 1.3, promptly notify the indemnifying party in writing
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party for
contribution or otherwise than under the indemnity agreement contained in this
Section 1.3 or to the extent it has not been materially prejudiced as a result
of such failure. In case any such action is brought against any indemnified
party and such indemnified party seeks or intends to seek indemnity from an
indemnifying party, the indemnifying party will be entitled to participate in,
and, to the extent that it may wish, jointly with all other indemnifying parties
similarly notified, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party; provided, however, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be a
conflict between the positions of the indemnifying party and the indemnified
party in conducting the defense of any such action or that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party which, if the
indemnifying party and the indemnified party were represented by the same
counsel, could materially prejudice the prosecution of defenses or actions
available to the indemnified party, the indemnified party or parties shall have
the right to select separate counsel to assume such legal defenses and to
otherwise participate in the defense of such action on behalf of such
indemnified party or parties. Upon receipt of notice from the indemnifying party
to such indemnified party of its election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 1.3 for any
legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof unless (i) the indemnified party shall have
employed such counsel in connection with the assumption of legal defenses in
accordance with the proviso to the preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel, approved by such indemnifying party,
representing the indemnified parties who are parties to such action) or (ii) the
indemnified party shall not have employed counsel reasonably satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of action, in each of which cases the reasonable
fees and expenses of counsel shall be at the expense of the indemnifying party.

         (d) If the indemnification provided for in this Section 1.3 is required
by its terms but is for any reason held to be unavailable to or otherwise
insufficient to hold harmless an

                                      -5-
<PAGE>
indemnified party under paragraphs (a), (b) or (c) of this Section 1.3 in
respect to any losses, claims, damages, liabilities or expenses referred to
herein, then each applicable indemnifying party shall contribute to the amount
paid or payable by such indemnified party as a result of any losses, claims,
damages, liabilities or expenses referred to herein (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Subscriber from the issuance of Preferred Shares or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but the relative fault of the Company and the Subscriber
in connection with the statements or omissions or inaccuracies in the
Registration Statement, the Prospectus or any amendment or supplement thereto
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations. The respective relative benefits
received by the Company on the one hand and each Subscriber on the other shall
be deemed to be in the same proportion as the amount paid by such Subscriber to
the Company pursuant to this Agreement for the Shares purchased by such
Subscriber that were sold pursuant to the Registration Statement bears to the
difference (the "Difference") between the amount such Subscriber paid for the
Shares that were sold pursuant to the Registration Statement and the amount
received by such Subscriber from such sale. The relative fault of such selling
Subscriber and the Company shall be determined by reference to, among other
things, whether the untrue or alleged statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by such Subscriber and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in paragraph (c) of this
Section 1.3, any legal or other fees or expenses reasonably incurred by such
party in connection with investigating or defending any action or claim. The
provisions set forth in paragraph (c) of this Section 1.3 with respect to the
notice of the threat or commencement of any threat or action shall apply if a
claim for contribution is to be made under this paragraph (d); provided,
however, that no additional notice shall be required with respect to any threat
or action for which notice has been given under paragraph (c) for purposes of
indemnification. The Company and each Subscriber agree that it would not be just
and equitable if contribution pursuant to this Section 1.3 were determined
solely by pro rata allocation (even if the Subscribers were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this paragraph.
Notwithstanding the provisions of this Section 1.3, no Subscriber shall be
required to contribute any amount in excess of the amount by which the
Difference exceeds the amount of any damages that such Subscriber has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Subscribers' obligations to contribute pursuant to this
Section 1.3 are several and not joint.

1.4 Termination of Conditions and Obligations. The conditions precedent imposed
by this Section 1 upon the transferability of the Shares shall cease and
terminate as to any particular number of the Shares upon the passage of
twenty-four months from the effective date of the Registration Statement
covering such Shares or at such time as an opinion of counsel satisfactory in
form and substance to the Company shall have been rendered to the effect that
such conditions are not necessary in order to comply with the Securities Act.

                                      -6-
<PAGE>
1.5 Information from Subscribers. Each Subscriber will as expeditiously as
possible (i) notify the Company of the occurrence of any event that makes any
statement made in the Registration Statement or the related prospectus regarding
such Subscriber untrue in any material respect or that requires the making of
any changes in the Registration Statement or the related prospectus so that, in
such regard, it will not contain any untrue statement of a material fact or omit
any material fact required to be stated therein or necessary to make the
statement not misleading and (ii) provide the Company with such information as
may be required to enable the Company to prepare a supplement or post-effective
amendment to the Registration Statement or a supplement to the related
prospectus.

SECTION 2. Liquidated Damages. If the Registration Statement has not been
declared effective by the SEC on or prior to the 90th day after the Effective
Date of the Amended Plan (a "Registration Default"), the Company agrees to pay
liquidated damages to each holder of Preferred Shares purchased pursuant to the
Commitment Agreement for each day that the Registration Default continues at the
annual rate of thirty cents ($.30) per share. All accrued liquidated damages
shall be paid to such holders of Preferred Shares by the Company on the last day
of each month during which a Registration Default occurs. Following the cure of
all Registration Defaults with respect to any particular Preferred Shares, the
accrual of liquidated damages with respect to such Preferred Shares will cease.

SECTION 3. Notices. All notices, requests, consents and other communications
hereunder shall be in writing, shall be mailed by first-class registered or
certified airmail, or when delivered by nationally recognized overnight express
courier postage prepaid or delivered by facsimile transmission during standard
business hours (from 8:00 a.m. to 6:00 p.m.), and shall be deemed given when so

                             OGLEBAY NORTON COMPANY

      1. Purpose. The purpose of this Management Stock Plan is to advance the
interests of the Corporation by encouraging and enabling the acquisition of a
larger personal proprietary interest in the Corporation by key employees of the
Corporation and its Subsidiaries upon whose judgment and keen interest the
Corporation is largely dependent for the successful conduct of its operations
and by providing such employees with incentives to put forth maximum efforts for
the success of the Corporation's business. It is anticipated that the
acquisition of such proprietary interest in the Corporation and such incentives
will stimulate the efforts of such employees on behalf of the Corporation and
its Subsidiaries and strengthen their desire to remain with the Corporation and
its Subsidiaries. It is also expected that such incentives and the opportunity
to acquire such a proprietary interest will enable the Corporation and its
Subsidiaries to attract desirable employees.

      Corporation or another Subsidiary is the sole general partner.

      3. Administration. The Plan shall be administered by a Committee of the
Board of Directors which shall consist of two or more directors of the
Corporation, each of whom shall be a "Non-Employee Director" within the meaning
of Rule 16b-3 under the Exchange Act and an "outside director" within the
meaning of Section 162(m) of the Internal Revenue Code. Notwithstanding the
foregoing, if at any time the Corporation is not required to register any class
of its equity securities under Section 12 of the Exchange Act, the Plan may be
administered by the Board of Directors during such time. During any period of
time in which the Plan is administered by the Board of Directors, all references
in the Plan to the Committee shall be deemed to refer to the Board of Directors.

                                       3
<PAGE>

      The Committee shall have full power and authority to administer and
interpret the Plan. Determinations of the Committee as to any question which may
arise with respect to the interpretation of the provisions of the Plan and
Incentive Awards shall be final. The Committee may authorize and establish such
rules, regulations and revisions thereof not inconsistent with the provisions of
the Plan, as it may deem advisable to make the Plan and Incentive Awards
effective or provide for their administration, and may take such other action
with regard to the Plan and Incentive Awards as it shall deem desirable to
effectuate their purpose.

      4. Participants. Except as hereinafter provided, the class of persons who
are potential recipients of Incentive Awards granted under this Plan shall
consist of employees of the Corporation or a Subsidiary, as determined by the
Committee. The parties to whom Incentive Awards are granted under this Plan, and
the number of Shares subject to each such Incentive Award, shall be determined
by the Committee in its sole discretion, subject, however, to the terms and
conditions of this Plan.

      5. Shares. Subject to the provisions of Section 15 hereof, the Committee
may grant Incentive Awards with respect to an aggregate of up to 1,328,049
Shares, all of which Shares may be either Shares held in treasury or authorized
but unissued Shares or a combination of the foregoing. The maximum number of
Shares which may be the subject of Options granted during any calendar year to
any Eligible Person shall not exceed 500,000 Shares and the aggregate number of
Shares actually issued or transferred by the Company upon the exercise of
Incentive Stock Options shall not exceed 1,325,397 shares of Common Stock. If
the Shares that would be issued or transferred pursuant to any Incentive Awards
are not issued or transferred and cease to be issuable or transferable for any
reason, or if Restricted Shares which are subject to a Restricted Stock Award
are forfeited, the number of Shares subject to such Incentive Award will no
longer be charged against the limitation provided for herein and may again be
made subject to Incentive Awards. Notwithstanding the preceding, with respect to
any Option granted to any individual who is a "covered employee" within the
meaning of Section 162(m) of the Internal Revenue Code that is canceled, the
number of shares subject to such Option shall continue to count against the
maximum number of Shares which may be the subject of Options granted to such
individual. For purposes of the preceding sentence, if, after grant, the
exercise price of an Option is reduced, such reduction shall be treated as a
cancellation of such Option and the grant of a new Option, and both the
cancellation of the Option and the new Option shall reduce the maximum number of
shares for which Options may be granted to the holder of such Option.

      6. Grant of Options; Initial Options. The number of Options to be granted
to any Eligible Person shall be determined by the Committee in its sole
discretion. At the time an Option is granted, the Committee may, in its sole
discretion, designate whether such Option (a) is to be considered as an
Incentive Stock Option, or (b) is not to be treated as an Incentive Stock Option
for purposes of this Plan and the Internal Revenue Code. No Option which is
intended to qualify as an Incentive Stock Option shall be granted under this
Plan to any individual who, at the time of such grant, is not an employee of the
Corporation or of a Subsidiary that satisfies the tests under Section 424(e) or
Section 424(f) of the Internal Revenue Code, or any successor provision.

      Notwithstanding any other provision of this Plan to the contrary, on or as
soon as practicable following the Effective Date, Options shall be granted with
respect to approximately 397,619 Shares (the "Initial Options") with a per share
exercise price of $12.63. Each of the

                                       4
<PAGE>

Initial Options shall become vested and exercisable by the Holder at the rate of
33-1/3% on each of the Effective Date, January 1, 2006 and January 1, 2007,
provided that the respective holder is still in the employ of the Corporation or
a Subsidiary on the applicable vesting date.

      Notwithstanding any other provision of this Plan to the contrary, to the
extent that the aggregate Fair Market Value (determined as of the date an Option
is granted) of the Shares with respect to which Options which are designated as
(or deemed to be) Incentive Stock Options granted to an employee (and any
incentive stock options granted to such employee under any other stock option
plan maintained by the Corporation or any Subsidiary that meets the requirements
of Section 422 of the Internal Revenue Code) first become exercisable in any
calendar year exceeds $100,000, such Options shall be treated as Options which
are not Incentive Stock Options. Options with respect to which no designation is
made by the Committee shall be deemed to be Incentive Stock Options to the
extent that the $100,000 limitation described in the preceding sentence is met
and the other applicable requirements for treatment as an Incentive Stock Option
are satisfied. This paragraph shall be applied by taking Options into account in
the order in which they are granted.

      Nothing herein contained shall be construed to prohibit the issuance of
Options at different times to the same person.

      An Option shall be evidenced by an agreement executed on behalf of the
Corporation and by the Eligible Person to whom the Option is granted. The form
of Option agreement shall be determined from time to time by the Committee, and
need not be identical with respect to each grantee.

      7. Purchase Price Under Options. The price per Share of the Shares to be
purchased pursuant to the exercise of any Option shall be fixed by the Committee
at the time of grant (except that such purchase price under the Initial Options
shall be as set forth in Section 6 hereof); provided, however, that the purchase
price per Share for the Shares to be purchased pursuant to the exercise of an
Incentive Stock Option shall not be less than the Fair Market Value of a Share
on the day on which the Option is granted.

      8. Duration of Options. The duration of any Option granted under this Plan
shall be fixed by the Committee at the time of grant; provided, however, that no
Option shall remain in effect for a period of more than ten years from the date
upon which the Option is granted.

      9. Ten Percent Stockholders. Notwithstanding any other provision of this
Plan to the contrary, no Option which is intended to qualify as an Incentive
Stock Option may be granted under this Plan to any employee who, at the time the
Option is granted, owns shares possessing more than 10 percent of the total
combined voting power or value of all classes of stock of the Corporation,
unless the exercise price under such Option is at least 110% of the Fair Market
Value of a Share on the date such Option is granted and the duration of such
Option is no more than five years.

      10. Exercise of Options. Except as otherwise provided herein (or in
Section 6 with respect to the Initial Options), Options, after the grant
thereof, shall become vested and exercisable by the holder at such rate and
times as may be fixed by the Committee at the time of grant.

                                       5
<PAGE>

      Notwithstanding any other provision of this Plan to the contrary, all or
any part of any remaining unexercised Options granted to any person shall be
vested and may be exercised upon the occurrence of any of the following (but in
no event after the expiration of the term of the Option): (i) a Change of
Control while the holder is in the employ of the Corporation or a Subsidiary,
(ii) a termination of employment by the Corporation or a Subsidiary without
Cause, or (iii) such special circumstance or event as in the opinion of the
Committee merits special consideration, provided that the Committee may, in its
sole discretion, require that any exercise of an Option on an accelerated basis
pursuant to subparagraph (iii) be contingent upon the consummation of the
applicable event giving rise to such acceleration. To the extent a holder's
Option is vested but unexercised upon the holder's termination of employment,
the holder may exercise the Option in accordance with Section 14.

      An Option shall be exercised by the delivery of a written notice duly
signed by the holder thereof to such effect, together with the Option agreement
and the full purchase price of the Shares purchased pursuant to the exercise of
the Option, to the Secretary of the Board of Directors or an officer of the
Corporation appointed by the Chairman of the Board of Directors for the purpose
of receiving the same. Payment of the full purchase price shall be made as
follows: in cash or by check payable to the order of the Corporation; by
providing with the exercise notice an order to a broker to sell part or all of
the Shares and to deliver sufficient proceeds to the Corporation, in cash or by
check payable to the order of the Corporation, to pay the full purchase price of
the Shares and all applicable withholding taxes; or by such other methods as the
Committee may permit from time to time.

      Within a reasonable time after the exercise of an Option, the Corporation
shall cause to be delivered to the person entitled thereto, the Shares purchased
pursuant to the exercise of the Option. If the Option shall have been exercised
with respect to less than all of the Shares subject to the Option, the
Corporation shall also cause to be delivered to the person entitled thereto a
new Option agreement in replacement of the agreement surrendered at the time of
the exercise of the Option, indicating the number of Shares with respect to
which the Option remains available for exercise, or the original Option
agreement shall be endorsed to give effect to the partial exercise thereof.

      Notwithstanding any other provision of the Plan or of any Option, no
Option granted pursuant to the Plan may be exercised at any time when the Option
or the granting or exercise thereof violates any law or governmental order or
regulation.

      11. Terms and Conditions of Restricted Stock Awards; Grant of Initial
Restricted Stock Awards. The Committee shall have the authority to grant to any
Eligible Person a Restricted Stock Award, subject to the following terms and
conditions:

            (a) All Restricted Shares granted to an Eligible Person pursuant to
the Plan shall be subject to the following conditions:

            (i) each grant shall be made without the payment of any
      consideration therefore by the Eligible Person;

            (ii) the Restricted Shares shall be subject to such transfer
      restrictions and risk of forfeiture as the Committee shall determine at
      the time the Restricted Stock Award is

                                       6
<PAGE>

      granted, until such specific conditions are met (which conditions shall be
      based solely on continuing employment and/or the lapse of time);

            (iii) the Restricted Shares may not be sold, transferred, or
      otherwise alienated or hypothecated until the restrictions are satisfied,
      removed or expire;

            (iv) each certificate representing Restricted Shares issued pursuant
      to a Restricted Stock Award under this Plan shall bear a legend making
      appropriate reference to the restrictions imposed; and

            (v) the Committee may impose such other conditions as it may deem
      advisable on any Restricted Shares granted to an Eligible Person pursuant
      to a Restricted Stock Award under this Plan, including, without
      limitation, restrictions under the requirements of any stock exchange upon
      which such Shares or shares of the same class are then listed, and under
      any securities law applicable to such Shares; provided, however, that such
      additional conditions shall not violate the specific requirements of
      clauses (i) and (ii) above.

            (b) The restrictions imposed under subsection (a) hereof upon
Restricted Shares shall lapse in accordance with a schedule or such other
conditions as shall be determined by the Committee, subject to the provisions of
subsection (c) below and Section 14 hereof.

            (c) On or as soon as practicable following the Effective Date,
Restricted Stock Awards shall be granted with respect to approximately 265,079
Shares. The Restricted Shares issued pursuant to such Restricted Stock Award
shall vest, and the restrictions imposed thereon under subsection (a) hereof
shall lapse, at the rate of 25% per year on each of July 1, 2005, July 1, 2006,
July 1, 2007 and July 1, 2008, subject to the provisions of Section 14 hereof.

            (d) Prior to the satisfaction, expiration or lapse of all of the
restrictions and conditions imposed upon Restricted Shares, a stock certificate
or certificates representing such Restricted Shares shall be registered in the
holder's name but shall be retained by the Corporation for the holder's account.
The holder shall have the right to vote such Restricted Shares and shall have
all other rights and privileges of a beneficial and record owner with respect
thereto, including, without limitation, the right to receive dividends,
distributions and adjustments with respect thereto; provided, however, that such
dividends, distributions and adjustments shall be retained by the Corporation
for the holder's account and for delivery to the holder, together with the stock
certificate or certificates representing such Restricted Shares, as and when
said restrictions and conditions shall have been satisfied, expired or lapsed.

            (e) A Restricted Stock Award shall be evidenced by an agreement
executed on behalf of the Corporation and by the Eligible Person to whom the
Restricted Stock Award is granted. The form of Restricted Stock Award agreement
shall be determined from time to time by the Committee, and need not be
identical with respect to each grantee.

      12. Consideration for Options. Except with respect to the Initial Options,
the Corporation shall obtain such consideration for the grant of an Option as
the Committee in its discretion may determine.

                                       7
<PAGE>

      13. Restrictions on Transferability of Incentive Awards. Except as
otherwise determined by the Board, an Incentive Award shall not be transferable
otherwise than by will or the laws of descent and distribution or as provided in
this Section 13. Except as otherwise determined by the Board with respect to
Options that are not Incentive Stock Options, Options shall be exercisable
during the initial holder's lifetime only by him or her or by his or her
guardian or legal representative.

      14. Termination of Employment. Except as otherwise provided herein, all or
any part of any Option, to the extent unexercised, shall terminate immediately,
upon the cessation or termination for any reason of the holder's employment by
the Corporation or any Subsidiary, except that the holder shall have three
months following the cessation of his employment with the Corporation or its
Subsidiaries, and no longer, within which to exercise any unexercised Options
which are vested but unexercised on the day on which such employment terminated;
provided, that such exercise must be accomplished prior to the expiration of the
term of such Option. Notwithstanding the foregoing, if the cessation of
employment is due to disability (as defined in Section 22(e)(3) of the Internal
Revenue Code) or to death, the holder or the representative of the Estate or the
heirs of a deceased holder shall have the privilege of exercising the Options
which are vested but unexercised at the time of such disability or death;
provided, however, that such exercise must be accomplished prior to the
expiration of the term of such Option and within one year of the holder's
disability or death, as the case may be. The Committee may, in its sole
discretion, extend the post-termination exercise period under this Section 14
with respect to any Option, but in no event beyond the expiration of the term of
such Option. If the employment of any holder of an Option with the Corporation
or a Subsidiary shall be terminated for Cause, all unexercised Options of such
holder shall terminate immediately upon such termination of the holder's
employment with the Corporation and all Subsidiaries, and a holder of Options
whose employment with the Corporation and Subsidiaries is so terminated, shall
have no right after such termination to exercise any unexercised Option he might
have exercised prior to the termination of his employment or service with the
Corporation and Subsidiaries.

      Except as hereinafter provided, if a holder of a Restricted Stock Award
shall voluntarily or involuntarily leave the employ of the Corporation or any
Subsidiary, then all Restricted Shares subject to restrictions at the time his
employment terminates (and any dividends, distributions and adjustments retained
by the Corporation with respect thereto) shall be forfeited. Notwithstanding the
foregoing, all restrictions to which Restricted Stock Awards are subject shall
lapse upon the occurrence of (i) the consummation of a Change of Control while
the holder is in the employ of the Corporation or a Subsidiary, (ii) a
termination of employment by the Corporation or a Subsidiary without Cause, or
(iii) such special circumstance or event as in the opinion of the Committee
merits special consideration.

      15. Adjustment Provision. The Board shall make or provide for such
adjustments in the numbers of Shares covered by outstanding Options or
Restricted Stock Awards granted hereunder, in the price, and in the kind of
shares covered thereby, as the Board, in its sole discretion, exercised in good
faith, may determine is equitably required to prevent dilution or enlargement of
the rights of holders of Incentive Awards that otherwise would result from (a)
any stock dividend, stock split, combination of shares, recapitalization or
other change in the capital structure of the Company, or (b) any merger,
consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial
or complete liquidation or other distribution of assets, issuance of

                                       8
<PAGE>

rights or warrants to purchase securities, or (c) any other corporate
transaction or event having an effect similar to any of the foregoing. Moreover,
in the event of any such transaction or event or in the event of a Change in
Control, the Board, in its discretion, may provide in substitution for any or
all outstanding Incentive Awards under this Plan such alternative consideration
as it, in good faith, may determine to be equitable in the circumstances and may
require in connection therewith the surrender of all awards so replaced. The
Board shall also make or provide for such adjustments in the number of shares
specified in Section 5 of this Plan as the Board in its sole discretion,
exercised in good faith, may determine is appropriate to reflect any transaction
or event described in this Section 15; provided, however, that any such
adjustment to the number specified in Section 5 shall be made only if and to the
extent that such adjustment would not cause any Option intended to qualify as an
Incentive Stock Option to fail so to qualify.

      16. Issuance of Shares and Compliance with Securities Act. The Corporation
may postpone the issuance and delivery of Shares pursuant to the grant or
exercise of any Incentive Award until (a) the admission of such Shares to
listing on the principal securities exchange or securities trading market on
which Shares of the Corporation of the same class are then listed or approved
for trading, and (b) the completion of such registration or other qualification
of such Shares under any State or Federal law, rule or regulation as the
Corporation shall determine to be necessary or advisable. Any holder of an
Incentive Award shall make such representations and furnish such information as
may, in the opinion of counsel for the Corporation, be appropriate to permit the
Corporation, in the light of the then existence or non-existence with respect to
such Shares of an effective Registration Statement under the Securities Act of
1933, as from time to time amended (the "Securities Act"), to issue the Shares
in compliance with the provisions of the Securities Act or any comparable act.
The Corporation shall have the right, in its sole discretion, to legend any
Shares which may be issued pursuant to the grant or exercise of any Incentive
Award, or may issue stop transfer orders in respect thereof.

      17. Income Tax Withholding. If the Corporation or a Subsidiary shall be
required to withhold any amounts by reason of any Federal, State, local or
foreign tax rules or regulations in respect of any Incentive Award, the
Corporation or the Subsidiary shall be entitled to take such action as it deems
appropriate in order to ensure compliance with such withholding requirements. In
order to facilitate payment by the holder of an Incentive Award of his
withholding obligations with respect to the Incentive Award, the Corporation or
Subsidiary may, at its election, (a) deduct from any cash payment otherwise due
to the holder, the appropriate withholding amount, (b) require the holder to pay
to the Corporation or Subsidiary in cash the appropriate withholding amount, (c)
permit the holder to elect to have the Corporation withhold a portion of the
Shares otherwise to be delivered with respect to such Incentive Award, the Fair
Market Value of which is equal to the minimum statutory withholding amount, or
(d) permit the holder to elect to deliver to the Corporation Shares already
owned by the holder for at least six months, the Fair Market Value of which is
equal to the appropriate withholding amount.

      18. Payment Restriction. Notwithstanding any provision of the Plan to the
contrary, the payment of all or any portion of the amounts payable hereunder
will be deferred to the extent that any amount payable, when added to any other
compensation received or to be received by a holder of an Incentive Award in the
same calendar year, would not be deductible by the Company or a Subsidiary by
reason of Section 162(m) of the Internal Revenue Code. The amount to be deferred
will equal the amount that otherwise would not be deductible by the Company or
Subsidiary by reason of Section 162(m) of the Internal Revenue Code, but in no

event greater than the total amount otherwise payable hereunder. The deferred
amount shall become payable on December 31 of the first succeeding calendar year
in which such amount, when added to all other compensation received or to be
received by the holder in such calendar year, would not be non-deductible by the
Company or Subsidiary by reason of Section 162(m) of the Internal Revenue Code.
The Committee, in its sole and absolute discretion, shall have the authority to
waive this payment restriction (in whole or in part) upon the written request of
the holder.

      19. Amendment of the Plan. Except as hereinafter provided, the Board of
Directors or the Committee may at any time withdraw or from time to time amend
the Plan as it relates to, and the terms and conditions of, any Incentive Awards
not theretofore granted, and the Board of Directors or the Committee, with the
consent of the affected holder of an Incentive Award, may at any time withdraw
or from time to time amend the Plan as it relates to, and the terms and
conditions of, any outstanding Incentive Award. Notwithstanding the foregoing,
any amendment by the Board of Directors or the Committee which would increase
the number of Shares issuable under the Plan or with respect to Options and
Rights granted to any individual during any calendar year or change the class of
Eligible Persons shall be subject to the approval of the shareholders of the
Corporation.

      20. No Right of Employment. Nothing contained herein or in an Incentive
Award shall be construed to confer on any employee any right to be continued in
the employ of the Corporation or any Subsidiary or derogate from any right of
the Corporation and any Subsidiary to retire, request the resignation of, or
discharge such employee, director or consultant (without or with pay), at any
time, with or without Cause.

      21. Effective Date of the Plan. This Plan shall be effective as of the
Effective Date. Confirmation of the Plan of Reorganization by the United States
Bankruptcy Court for the District of Delaware having jurisdiction over the
Corporation's and Subsidiaries' Chapter 11 cases, pursuant to the applicable
provisions of the Bankruptcy Code, shall be deemed to constitute shareholder
approval of this Plan for all applicable purposes.

      22. Final Grant Date. No Incentive Award shall be granted under the Plan
after the date which is the day before the tenth anniversary of the Effective
Date.

      23. Governing Law. The Plan shall be construed, administered, and enforced

are preempted by the federal laws of the United States of America, and the venue
for all actions or proceedings brought by any party arising out of or relating
to the Plan shall be in the state or federal courts, as the case may be, located
in Cleveland, Ohio. The Company and the participants in the Plan hereby
irrevocably waive any objection which they now or hereafter may have to the
laying of venue of any action or proceeding arising out of or relating to the
Plan brought in any such courts and any objection on the ground that any such
action or proceeding in any such courts has been brought in an inconvenient
forum.

      24. Severability. If any term or condition of the Plan shall be invalid or
unenforceable to any extent or in any application, then the remainder of the
Plan, with the exception of such invalid or unenforceable provision, shall not
be affected thereby and shall continue in effect and application to its fullest
extent.

      IN WITNESS WHEREOF, the Corporation has caused there presents to be
executed by its duly authorized officer as of the Effective Date.
