("NOTES") claims on ___________, 2004 (the "RECORD DATE") who is not a party to
the commitment agreement (as described in the Prospectus) under the second
amended joint plan of reorganization as confirmed by the United States
Bankruptcy Court for the District of Delaware on November 16, 2004 (the "PLAN")
of subscription rights, CUSIP No. 677007 12 2 (the "RIGHTS") to purchase its

Subscription Agreement.

TERMS OF THIS RIGHTS OFFERING

      Non-certificated Rights will be issued to holders of Notes claims who are
not parties to the commitment agreement through the Rights Offering. The
subscription rights allow you to subscribe for and purchase 80 Shares for each
$1,000 in principal amount of allowed Notes claims held by you at a purchase
price of $800 (a price of $10 per share) (the "SUBSCRIPTION PURCHASE PRICE").
The aggregate number of Shares that may be subscribed for and purchased pursuant
to the Rights will be 5,012,160 shares of convertible preferred stock. There are
no oversubscription privileges associated with the Rights Offering.

      The Rights expire at 5:00 p.m., Eastern time, on ____________, 2004 (the
"EXPIRATION TIME"). ANY RIGHTS THAT REMAIN UNEXERCISED AFTER THE EXPIRATION TIME
WILL NO LONGER BE EXERCISABLE AND WILL CEASE TO HAVE ANY VALUE.

      IF YOU ARE A BENEFICIAL OWNER OF THE NOTES AND RECEIVE YOUR RIGHTS THROUGH
A BROKER, TRUSTEE OR OTHER NOMINEE, WE HAVE ASKED YOUR BROKER, TRUSTEE OR OTHER
NOMINEE TO NOTIFY YOU OF THE RIGHTS OFFERING. IF YOU WISH TO EXERCISE YOUR
RIGHTS, YOU SHOULD HAVE YOUR BROKER, TRUSTEE OR OTHER NOMINEE ACT FOR YOU. TO
INDICATE YOUR DECISION WITH RESPECT TO YOUR RIGHTS, YOU SHOULD COMPLETE AND
RETURN TO YOUR BROKER, TRUSTEE OR OTHER NOMINEE THE FORM ENTITLED "INSTRUCTIONS
BY BENEFICIAL OWNER TO BROKER, TRUSTEE OR OTHER NOMINEE" OR SUCH OTHER FORM AS
YOUR BROKER, TRUSTEE OR NOMINEE MAY PROVIDE. YOU SHOULD RECEIVE THESE FORMS FROM
YOUR BROKER, TRUSTEE OR OTHER NOMINEE WITH THE OTHER RIGHTS OFFERING MATERIALS.

      IF AT OR PRIOR TO THE EXPIRATION TIME, THE SUBSCRIPTION AGENT FOR ANY
REASON DOES NOT RECEIVE ON BEHALF OF A GIVEN HOLDER OF RIGHTS EITHER A DULY
COMPLETED SUBSCRIPTION AGREEMENT OR "NOMINEE HOLDER CERTIFICATION" EXECUTED BY
THE BROKER, TRUSTEE OR OTHER NOMINEE AND NOTICE OF EXERCISE THROUGH ASOP ALONG
WITH IMMEDIATELY AVAILABLE FUNDS PAYABLE TO THE SUBSCRIPTION



AGENT IN AN AMOUNT EQUAL TO THE RIGHTS HOLDER'S SUBSCRIPTION PURCHASE PRICE, THE
HOLDER OF RIGHTS WILL BE DEEMED TO HAVE RELINQUISHED AND WAIVED ITS RIGHT TO
PARTICIPATE IN THE RIGHTS OFFERING.

      Oglebay Norton will issue the Shares only if, and at such time as, the
effective date of the Plan occurs and the second amended and restated articles
of incorporation of Oglebay Norton are filed. Oglebay Norton will hold payments
made by holders of Rights participating in the Rights Offering pursuant to the
procedures set forth on the Subscription Agreement in an interest-bearing escrow
account until the earlier of the effective date of the Plan, which we anticipate
to occur on ______________, 2004, or the date on which Oglebay Norton withdraws
the Plan. If the Rights Offering is terminated or the effective date of the Plan
does not occur, Oglebay Norton will return the payments to the participating
holders of Rights to the addresses indicated on their respective ballots.
Interest will be paid to the holders of Rights only if Oglebay Norton returns
the payments for the reasons stated above; otherwise, Oglebay Norton will not
pay interest to the holders of Rights electing to subscribe for and purchase the
Shares.

NO REVOCATION

      After you have subscribed to purchase the Shares, the subscription may not
be revoked.

CONDITIONS

      The issuance of the Shares is conditioned on the confirmation of the Plan,
the occurrence of the effective date of the Plan and the filing of the second
amended and restated articles of incorporation of Oglebay Norton.

INSTRUCTIONS

1.    EXERCISING RIGHTS THROUGH YOUR BROKER, TRUSTEE OR OTHER NOMINEE

      If you are a beneficial owner of the Notes and receive your Rights through
a broker, trustee or other nominee, we have asked your broker, trustee or other
nominee to notify you of the Rights Offering. If you wish to exercise your
Rights, you should have your broker, trustee or other nominee act for you. To
indicate your decision with respect to your Rights, you should complete and
return to your broker, trustee or other nominee the form entitled "Instructions
by Beneficial Owner to Broker, Trustee or Other Nominee" or such other form as
your broker, trustee or other nominee may provide. You should receive this form
from your broker, trustee or other nominee with the other Rights Offering
materials.

2.    TRANSFER OF RIGHTS

      The Rights are transferable; provided, however, that any Rights held by an
affiliate of Oglebay Norton may generally only be resold pursuant to a valid
exemption under the Securities Act of 1933. The Rights are separate from the
Notes; therefore, you may transfer your Rights and retain your Notes if you
wish. For treatment of the Notes under the Plan, please refer to the applicable
sections of the Plan, a copy of which is attached as Annex A to the enclosed
Prospectus.

                                        2


3.    EXECUTION BY PERSON WHO IS A REGISTERED BUT NOT BENEFICIAL HOLDER

      Persons who sign the Subscription Agreement or the "Nominee Holder
Certificate" in a representative or other fiduciary capacity as a broker,
trustee or other nominee must indicate their capacity when signing and, unless
waived by the Subscription Agent in its sole and absolute discretion, must
present to the Subscription Agent satisfactory evidence of their authority to so
act.

4.    PROCEDURES FOR DTC PARTICIPANTS

      The exercise of your Rights will only be made through the ASOP facilities
of DTC. If the Rights held by you as a broker, trustee or other nominee are held
of record through DTC, the Rights will only be exercised by instructing DTC to
transfer the Rights from your account to the account of the Subscription Agent,
together with either the Subscription Agreement or the "Nominee Holder
Certification" as to the aggregate number of rights you are exercising and the
number of Shares you are subscribing for and your Subscription Purchase Price
for each share you subscribed for pursuant to your Rights. Payment of the
Subscription Purchase Price will be made in accordance with customary procedures
of ASOP.

5.    METHOD OF DELIVERY

      The method of delivery of Subscription Agreement or the "Nominee Holder
Certification" by the broker, trustee or other nominee to the Subscription Agent
will be at the broker, trustee or other nominee's election and risk. If sent by
mail, it is recommended that they be sent by registered mail, properly insured,
with return receipt requested. If sent by facsimile, it is recommended that you
call the Subscription Agent to confirm receipt thereof. In either case, a
sufficient number of days should be allowed to ensure delivery to the
Subscription Agent and the clearance of payment prior to the Expiration Time.
Payment of the Subscription Purchase Price will be made in accordance with
customary procedures of ASOP.
