                           2005 MANAGEMENT STOCK PLAN
                                       OF
                             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.

      2. Definitions. When used in this Plan, unless the context otherwise
requires:

      Award, the following: (i) if the holder has an employment agreement in
      effect with the Corporation or a Subsidiary which contains a definition of

      shall be as defined in such employment agreement, or (ii) if the holder
      does not have an employment agreement in effect with the Corporation or a
      Subsidiary which contains a definition of cause, then "Cause" for purposes
      of the Plan shall mean (A) the holder's failure to properly perform the
      holder's duties for the Corporation or a Subsidiary (except due to
      physical or mental impairment); (B) the holder's material violation of

      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

                                       9

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
according to the laws of the State of Ohio, except to the extent that such laws
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.
