                             STOCK OPTION AGREEMENT

         THIS AGREEMENT, made as of __________________, 2005 (the "Grant Date"),
by and between OGLEBAY NORTON COMPANY (the "Corporation") and __________________
(the "Holder").

         WHEREAS, the Corporation has established the 2005 Management Stock Plan
of Oglebay Norton Company (the "Management Stock Plan") in order to provide
additional incentives to certain employees of the Corporation and its
Subsidiaries; and

         WHEREAS, the Corporation has granted an option to the Holder pursuant
to the Management Stock Plan as provided herein; and

         WHEREAS, the Holder is an employee who is employed by the Corporation;

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Grant of Option.

                  1.1 The Corporation hereby grants to the Holder the right and
option (the "Option") to purchase all or any part of an aggregate of ___________
Shares, subject to, and in accordance with, the terms and conditions set forth
in this Agreement and the Management Stock Plan.

                  1.2 The Option and this Agreement are subject to all of the
terms and conditions of the Management Stock Plan, which terms and conditions
are hereby incorporated by reference. Except as otherwise expressly set forth
herein, the capitalized terms used in this Agreement shall have the same
definitions as set forth in the Management Stock Plan.

         2. Exercise Price. The price at which the Holder shall be entitled to
purchase Shares upon the exercise of the Option shall be $12.63 per Share.

         3. Duration of Option. The Option shall expire on the tenth anniversary
of the Grant Date.

         4. Vesting and Exercisability of Option. Except as otherwise provided
pursuant to the acceleration provisions of the Plan, the Option shall vest and
become exercisable at the rate of 33-1/3% on each of the Effective Date (as
defined in the Management Stock Plan), January 1, 2006 and January 1, 2007,
provided that the Holder is still in the employ of the Corporation or a
Subsidiary on each such respective vesting date. In no event, however, may the
Option be exercised on or after the Option's expiration date or after an earlier
termination of exercisability of the Option pursuant to the Plan in connection
with the Holder's termination of employment with the Corporation or its
Subsidiaries.

         5. Non-Transferability of Option. The Option shall not be transferable
by the Holder otherwise than by will or by the laws of descent and distribution
and shall be exercisable during the Holder's lifetime only by the Holder, or in
the event of Holder's legal incapacity, by the Holder's guardian or legal
representative acting on behalf of Holder in a fiduciary capacity under state
law and court supervision.

         6. No Rights as a Stockholder. The Holder shall not have any rights or
privileges of a stockholder with respect to any Shares until the date of
issuance by the Corporation of such Shares pursuant to the exercise of the
Option.

         7. Additional Provisions Related to Exercise. In the event of the
exercise of the Option at a time when there is not in effect a registration
statement under the Securities Act of 1933, as amended, relating to the Shares,
the Holder hereby represents and warrants, and by virtue of such exercise shall
be deemed to represent and warrant, to the Corporation that the Shares are being
acquired for investment only and not with a view to the distribution thereof,
and the Holder shall provide the Corporation with such further representations
and warranties as the Corporation may reasonably require in order to ensure
compliance with applicable federal and state securities, "blue sky" and other
laws. No Shares shall be purchased upon the exercise of the Option unless and
until the Corporation and/or the Holder shall have complied with all applicable
federal or state registration, listing and/or qualification requirements and all
other requirements of law or of any regulatory agencies having jurisdiction.

         8. Restrictive Legend. Any stock certificate representing Shares issued
upon exercise of the Option shall, if applicable, bear a legend making
appropriate references to any restrictions imposed by stock exchange and/or
securities law requirements. Notwithstanding any other provision of this
Agreement or the Management Stock Plan to the contrary, in lieu of issuing one
or more stock certificates representing Shares, record ownership of the Shares
issued pursuant to the exercise of the Option in the name of the Holder may, in
the sole discretion of the Corporation, be evidenced by appropriate entry in the
Corporation's stock ownership records, in which case the Holder may receive a
certificate or certificates representing such Shares only by written request to
the Corporation.

         9. Holder Bound by the Plan. The Holder hereby acknowledges receipt of
a copy of the Management Stock Plan and agrees to be bound by all the terms and
provisions thereof, including, without limitation, the Corporation's and
Subsidiaries' tax withholding rights with respect to the Shares issued pursuant
to any exercise of the Option. A determination of the Committee as to any
questions which may arise with respect to the interpretation of the provisions
of this Agreement and of the Management Stock Plan shall be final. The Committee
may authorize and establish such rules, regulations and revisions thereof not
inconsistent with the provisions of the Management Stock Plan, as it may deem
advisable to effectuate the purpose of the grant of the Option.

         10. Modification of Agreement. This Agreement may be modified, amended,
suspended or terminated, and any terms or conditions may be waived, but only by
a written instrument executed by the parties hereto.

                           RESTRICTED STOCK AGREEMENT

         THIS AGREEMENT, made as of _________, 2005, by and between OGLEBAY
NORTON COMPANY (the "Corporation") and _____________ (the "Recipient").

         WHEREAS, the Corporation has established the 2005 Management Stock Plan
of Oglebay Norton Company (the "Management Stock Plan") pursuant to which shares
of the Corporation's common stock, par value $0.01 per share ("Shares"), may be
awarded to employees of the Corporation and its Subsidiaries; and

         WHEREAS, the Corporation has granted to the Recipient a restricted
stock award pursuant to the Management Stock Plan; and

         WHEREAS, it is intended that this Agreement shall set forth the terms,
conditions and restrictions imposed with respect to said restricted stock award;

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Restricted Stock Award.

                  1.1 Pursuant to the Management Stock Plan, the Recipient has
been awarded on _______________, 2005 (the "Award Date"), a restricted stock
award with respect to __________ Shares (the "Restricted Stock Award"), subject
to the terms, conditions and restrictions set forth in the Management Stock Plan
and in this Agreement.

                  1.2 The Restricted Stock Award and this Agreement are subject
to all of the terms and conditions of the Management Stock Plan, which terms and
conditions are hereby incorporated by reference. Except as otherwise expressly
set forth herein, the capitalized terms used in this Agreement shall have the
same definitions as set forth in the Management Stock Plan.

         2. Vesting and Restrictions. Restrictions shall be imposed on a
transfer of the Shares issued pursuant to the Restricted Stock Award, and such
Shares shall be subject to risk of forfeiture, as follows:

The Shares issued pursuant to the Restricted Stock Award shall become vested at
the rate of 25% per year on each of July 1, 2005, July 1, 2006, July 1, 2007 and
July 1, 2008, provided the Recipient is still in the employ of the Corporation
or a Subsidiary on each such respective vesting date. Restrictions shall be
imposed on any transfer of the Shares subject to the Restricted Stock Award
until such time as the Shares shall become vested in accordance with this
Section 2. If the Recipient's employment with the Corporation and its
Subsidiaries terminates prior to the date on which the Shares become vested, any
Shares (and any dividends, distributions and

<PAGE>

adjustments with respect thereto) which were not theretofore vested shall be
forfeited. Notwithstanding the preceding, 100% of the Shares shall become vested
in the event of any of the following: (i) the consummation of a Change in
Control while the Recipient is in the employ of the Corporation or a Subsidiary,
(ii) termination of the Recipient's 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. Any other applicable
restrictions or conditions under the requirements of any stock exchange upon
which the Shares issued pursuant to the Restricted Stock Award or shares of the
same class are then listed, and under any securities law applicable to such
Shares, shall be imposed.

         3. Stockholder Rights. Except to the extent of the restrictions set
forth in Section 2, the Recipient shall have all the rights and privileges of a
beneficial and record owner with respect to the Shares issued pursuant to the
Restricted Stock Award; provided, however, that (i) any stock certificate or
certificates representing such Shares shall be retained by the Corporation for
the Recipient's account until such Shares become vested, and (ii) dividends,
distributions and adjustments with respect to such Shares shall be subject to
the same restrictions and risk of forfeiture as are imposed on the Shares, and
shall be retained by the Corporation for the Recipient's account and for
delivery to the Recipient, together with the stock certificate or certificates
representing such Shares, if, as and when such Shares become vested.

         4. Restrictive Legend. Any certificate representing Shares issued
pursuant to the Restricted Stock Award shall bear a legend making appropriate
references to the restrictions imposed by this Agreement. At such time as Shares
become vested pursuant to this Agreement, a new certificate representing such
Shares shall be issued (in substitution for the prior certificate) which shall,
if applicable, bear a legend making appropriate references to any restrictions
imposed by stock exchange and/or securities law requirements. Notwithstanding
any other provision of this Agreement or the Management Stock Plan to the
contrary, in lieu of issuing one or more stock certificates representing Shares,
record ownership of the Shares issued pursuant to the Restricted Stock Award in
the name of the Recipient may, in the sole discretion of the Corporation, be
evidenced by appropriate entry in the Corporation's stock ownership records, in
which case the Recipient may receive a certificate or certificates representing
such Shares only by written request to the Corporation.

         5. Recipient Bound by the Management Stock Plan. The Recipient hereby
acknowledges receipt of a copy of the Management Stock Plan and agrees to be
bound by all the terms and provisions thereof, including, without limitation,
the Corporation's and Subsidiaries' tax withholding rights with respect to the
Shares issued pursuant to the Restrictive Stock Award. A determination of the
Committee as to any questions which may arise with respect to the interpretation
of the provisions of this Agreement and of the Management Stock Plan shall be
final. The Committee may authorize and establish such rules, regulations and
revisions thereof not inconsistent with the provisions of the Management Stock
Plan, as it may deem advisable to effectuate the purpose of the grant of the
Restricted Stock Award.
