 - 3 - 

	 	(v)	the words “herein”, “hereof”, “hereunder” and other words of similar import refer to this Warrant Agent Agreement as a whole and not to any particular
provision; 

  

	 	(vi)	the words “include” and “including” will mean without limitation by reason of enumeration; and 

  

	 	(vii)	the headings in this Warrant Agent Agreement are solely for convenience of reference and will be given no effect in the construction or interpretation of this Warrant Agent
Agreement. 

  
 SECTION 2. Appointment of Warrant
Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with the instructions set forth hereinafter in this Warrant Agent Agreement, and the Warrant Agent hereby accepts such appointment, upon the terms
and conditions hereinafter set forth. 
  
 SECTION 3. Form of
Warrant Certificates. Subject to the provisions of this Warrant Agent Agreement, in accordance with the terms of the Plan, on the Effective Date, Warrants to purchase the Warrant Shares will be issued by the Company in the amounts and to the
recipients specified in the Plan. The Warrants will be issued in definitive form (the “Definitive Warrants”), substantially in the form of Exhibit A-1, and in global form (the “Global Warrants”), substantially in the form of
Exhibit A-2. Each certificate representing Global Warrants will represent such of the outstanding Warrants as will be specified therein and each certificate will provide that it will represent the aggregate amount of outstanding Warrants from time
to time endorsed thereon and that the aggregate amount of outstanding Warrants represented thereby may from time to time be reduced or increased, as appropriate. The Depository Trust Company (the “Depositary”) will act as securities
depositary for the Global Warrants. Upon request, a Holder may receive from the Depositary and the Warrant Agent separate Definitive Warrants as set forth in Section 6 below. Any certificates evidencing the Definitive Warrants (the “Definitive
Warrant Certificates”) or the Global Warrants (the “Global Warrant Certificates”) to be delivered pursuant to this Warrant Agent Agreement will be substantially in the forms set forth in Exhibit A-1 and Exhibit A-2, respectively,
attached hereto. 
  
 SECTION 4. Execution of Warrant
Certificates. Warrant Certificates will be signed on behalf of the Company by its Chairman of the Board of Directors or its President and Chief Executive Officer or a Vice President and by its Secretary or an Assistant Secretary (each, an
“Officer”). Each such signature upon the Warrant Certificates may be in the form of a facsimile signature of any present or any future Officer and may be imprinted or otherwise reproduced on the Warrant Certificates and for that purpose
the Company may adopt and use the facsimile signature of any such Officer. 
  
 If any Officer who will have signed any of the Warrant Certificates will cease to be such Officer before the Warrant Certificates so signed will have been countersigned by the Warrant Agent, or disposed of by the
Company, such Warrant Certificates nevertheless may be 

  

 - 4 - 

 
countersigned and delivered or disposed of as though such person had not ceased to be such Officer; and any Warrant Certificate may be signed on behalf of
the Company by any person who, at the actual date of the execution of such Warrant Certificate, will be an Officer, although at the date of the execution of this Warrant Agent Agreement any such person was not such an Officer. 
  
 SECTION 5. Issuance of Warrants; Registration and Countersignature.
The Warrant Agent, on behalf of the Company, will (a) number the Warrant Certificates received from the Company, (b) insert the name of the Holder and the number of Warrants and Warrant Shares such Holder is entitled to receive on each respective
Warrant Certificate based on the information provided in the Distribution Record Date Stock Register to the Warrant Agent by the Company, and (c) register the Warrant Certificates in a register as they are issued. 
  
 The Warrant Agent will also countersign the Warrant Certificates. Warrant
Certificates will be countersigned manually by the Warrant Agent and will not be valid for any purpose unless so countersigned. The Warrant Agent will, upon written instructions of the Chairman of the Board of Directors, the President and Chief
Executive Officer or a Vice President of the Company, initially countersign, issue and deliver Warrants entitling the Holders thereof to purchase approximately the number of Warrant Shares referred to in Recital B above and will countersign and
deliver Warrants as otherwise provided in this Warrant Agent Agreement. 
  
 On the Effective Date, the Warrant Agent will then arrange to deliver or cause to be delivered, by first class mail or overnight courier, the Warrant Certificates to the respective Holders at the mailing address set forth in the
Distribution Record Date Stock Register. 
  
 The Company and the
Warrant Agent may deem and treat the Holder(s) of the Warrant Certificates as the absolute owner(s) thereof (notwithstanding any notation of ownership or other writing thereon made by anyone), for all purposes, and neither the Company nor the
Warrant Agent will be affected by any notice to the contrary. 
  
 SECTION 6. Registration of Transfers and Exchanges. 
  
 (a) Transfer and Exchange of Definitive Warrants. When Definitive Warrant Certificates are presented to the Warrant Agent with a written request: 
  

	 	(i)	to register the transfer of the Definitive Warrant Certificates; or 

  

	 	(ii)	to exchange such Definitive Warrant Certificates for an equal number of Definitive Warrants of other authorized denominations, the Warrant Agent will register the transfer or make
the exchange as requested if its requirements for such transactions are met; provided, however, that the Definitive Warrant Certificates presented or surrendered for registration of transfer or exchange: 

  

	 	(A)	will be duly endorsed or accompanied by a written instruction of transfer in the form required by the Warrant Agent Agreement or satisfactory to the Warrant Agent, duly executed by
the Holder thereof or by his attorney, duly authorized in writing; and 

  

 - 5 - 

	 	(B)	upon the request of the Company, such request will be accompanied by evidence, including an opinion of counsel if requested, reasonably satisfactory to the Company (and its counsel)
that either: 

  

	 	(1)	the Warrant is being delivered to the Warrant Agent by a Holder for registration in the name of such Holder, without transfer; or 

  

	 	(2)	the Warrant is being transferred in reliance on an exemption from the registration requirements of the Securities Act. 

  
 (b) Exchange of a Definitive Warrant for a Beneficial Interest in a Global
Warrant. Upon receipt by the Warrant Agent of a Definitive Warrant that is not a restricted Warrant, duly endorsed or accompanied by appropriate instruments of transfer, in the form required by this Warrant Agent Agreement or satisfactory to the
Warrant Agent, together with, written instructions directing the Warrant Agent to make, or to direct the Depositary to make, an endorsement on the Global Warrant Certificate to reflect an increase in the number of Warrants represented by the Global
Warrant Certificate, then the Warrant Agent will cancel such Definitive Warrant and cause, or direct the Depositary to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Warrant Agent, the
number of Warrants represented by the Global Warrant Certificate to be increased accordingly. If no Global Warrant Certificate is then outstanding, the Company will issue and the Warrant Agent will countersign a new Global Warrant Certificate
representing the appropriate number of Warrants. 
  
 (c)
Transfer and Exchange of Global Warrants or Beneficial Interests Therein. The transfer and exchange of Global Warrants or beneficial interests represented by a Global Warrant Certificate will be effected through the Depositary, in accordance
with this Warrant Agent Agreement and the procedures of the Depositary therefor. 
  
 (d) Exchange of a Beneficial Interest in a Global Warrant for a Definitive Warrant. 
  

	 	(i)	 Any person having a beneficial interest in a Global Warrant may, upon written request to the Warrant Agent, exchange such beneficial interest for a certificate
representing a Definitive Warrant. Upon receipt by the Warrant Agent of written instructions or such other form of instructions (as is customary for the Depositary) from the Depositary or its nominee on behalf of any person having a beneficial
interest in a Global Warrant, the Warrant Agent will cause, in accordance with the standing instructions and procedures existing between the Depositary and 

  

 - 6 - 

	 	 
Warrant Agent, a Definitive Warrant Certificate representing the number of Warrants representing such person’s beneficial interests to be issued and
simultaneously reduce the number of Warrants represented by the Global Warrant Certificate. 

  

	 	(ii)	Definitive Warrant Certificates issued in exchange for beneficial interests represented by a Global Warrant pursuant to this Section 6(d) will be registered in such names as the
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, will instruct the Warrant Agent. The Warrant Agent will deliver such Definitive Warrant Certificates to the persons in whose names such Warrants are so
registered. 

  
 (e) Restrictions on Transfer and
Exchange of Global Warrants. Notwithstanding any other provisions of this Warrant Agent Agreement (other than the provisions set forth in Subsection (g) of this Section 6), a Global Warrant Certificate may not be transferred as a whole except by
the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

  
 (f) Countersigning of Definitive Warrants in Absence of
Depositary. If at any time: 
  

	 	(i)	the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Global Warrants and a successor Depositary for the Global Warrants is not
appointed by the Company within five Business Days after delivery of such notice; or 

  

	 	(ii)	the Company, in its sole discretion, notifies the Warrant Agent in writing that it elects to cause the issuance of Definitive Warrant Certificates under this Warrant Agent
Agreement, 

  
 then the Company will execute, and the Warrant Agent,
upon written instructions signed by two Officers of the Company, will countersign and deliver Definitive Warrant Certificates, in an aggregate number equal to the number of Warrants represented by Global Warrants, in exchange for such Global
Warrants. 
  
 (g) Cancellation of Global Warrant. At such
time as all beneficial interests in Global Warrants have either been exchanged for Definitive Warrants, exercised, redeemed, repurchased or cancelled, all Global Warrant Certificates will be returned to, and then cancelled by, the Warrant Agent.

  
 (h) Obligations with respect to Transfers and Exchanges of
Warrants. 
  

	 	(i)	To permit registrations of transfers and exchanges, the Company will execute and the Warrant Agent is hereby authorized to countersign, in accordance with the provisions of Section
5 and this Section 6, Definitive Warrant Certificates and Global Warrant Certificates as required pursuant to the provisions of this Section 6. 

  

 - 7 - 

	 	(ii)	All Definitive Warrant Certificates and Global Warrant Certificates issued upon any registration of transfer or exchange of Definitive Warrants or Global Warrants will be the valid
obligations of the Company, entitled to the same benefits under this Warrant Agent Agreement, as the Definitive Warrants or Global Warrants surrendered upon such registration of transfer or exchange. 

  

	 	(iii)	Prior to due presentment for registration of transfer of any Warrant, the Warrant Agent and the Company may deem and treat the person in whose name any Warrant is registered as the
absolute owner of such Warrant, and neither the Warrant Agent nor the Company will be affected by notice to the contrary. 

  

	 	(iv)	No service charge will be made to a Holder for any registration, transfer or exchange, but the Company may require payment of a sum sufficient to cover any stamp or other
governmental charge that may be imposed on a Holder in connection with any such exchange or registration of transfer. 

  
 SECTION 7. Terms of Warrants; Exercise of Warrants. (a) Each Warrant will be exercisable at any time and from time to time beginning on the
Effective Date and ending on 5:00 p.m., Eastern time, on the Expiration Date. After 5:00 p.m., Eastern time, on the Expiration Date, the Warrants will become void and of no value and all rights of the holder under the Warrant Certificate evidencing
such Warrant and under this Warrant Agent Agreement will cease. On the Effective Date, each record holder of Old Common Stock as of the close of business on the Distribution Record Date will receive one Warrant for each share of Old Common Stock
then held. Subject to the provisions of this Warrant Agent Agreement and applicable law, each Warrant issued on the Effective Date will entitle the Original Holder thereof to purchase from the Company (and the Company will issue and sell to such
Original Holder) one-tenth (1/10th) of a fully paid and nonassessable share of New Common Stock. The Warrants will entitle the Holder thereof to purchase at the Exercise Price one Common Share for each ten (10) Warrants held. Except in the case
where a Holder is exercising all Warrants then held, Warrant Shares may be purchased only pursuant to the exercise of Warrants in integral multiples of ten (10). No fractions of a Warrant Share will be issued upon exercise of any Warrants. If any
fraction of a Warrant Share would be issuable on the exercise of all Warrants then held by a Holder, the number of Warrant Shares issuable to such Holder pursuant to such Warrants will reflect a rounding to the nearest whole number of Warrant Shares
to be issued (up or down), with half shares being rounded up as provided in Section 11. The Warrants are transferable; provided, however, that any Warrants held by an affiliate of the Company may generally only be resold pursuant to a valid
exemption under the Securities Act. The Warrants are exercisable by the subsequent Holder thereof pursuant to the terms and conditions provided in this Warrant Agent Agreement. 
  

 - 8 - 

 (b) Warrants may be exercised upon surrender to the Company at the principal office of the Warrant Agent
of (i) the certificate or certificates evidencing the Warrants to be exercised, (ii) the form of election to purchase on the reverse of such certificate or certificates (the “Warrant Exercise Notice”) duly filled in and signed, which
signature must be guaranteed by an Eligible Guarantor Institution pursuant to SEC Rule 17Ad-15, and (iii) payment to the Warrant Agent, for the account of the Company, of the amount equal to the Exercise Price multiplied by the number of shares of
New Common Stock (the “Exercise Amount”) of which such Warrants are then exercised. Payment of the Exercise Amount will be made to the Warrant Agent by certified check, official bank check, express money order, payable to the order of the
Company, or by wire transfer in immediately available funds as follows:

 As Agent for Oglebay Norton Company 
 Attn: Jane Schweiger 
  
 The exercise of Warrants by Holders of beneficial interest in Global Warrants will be effected in accordance with this
Warrant Agent Agreement and the procedures of the Depository therefor. 
  
 (c) All Warrant Certificates surrendered upon exercise of Warrants will be cancelled by the Warrant Agent. Such cancelled Warrant Certificates will then be disposed of by the Warrant Agent in accordance with the Warrant Agent’s
customary procedures and shall provide evidence to the Company upon its request of any such cancelled Warrant Certificates. The Warrant Agent will account promptly to the Company with respect to Warrants exercised and concurrently pay to the Company
all monies received by the Warrant Agent for the purchase of the Warrant Shares through the exercise of such Warrants. On or before the third day following the Expiration Date, the Warrant Agent will certify in writing, delivered as provided in
Section 15 hereof, the actual number of Warrants exercised and paid for as of 5:00 p.m., Eastern time, on the Expiration Date. 
  
 (d) Any exercise of a Warrant pursuant to the terms of this Warrant Agent Agreement will be irrevocable and will constitute a binding agreement between
the Holder and the Company, enforceable in accordance with its terms. 
  
 (e) The Warrant Agent will: 
  

	 	(i)	 examine all Warrant Exercise Notices and all other documents delivered to it by or on behalf of Holders as contemplated by the Warrant Certificates to ascertain
whether, on their face, such Warrant Exercise Notices and any such other documents have been 

  

 - 9 - 

	 	 
executed and completed in accordance with their terms and the terms of the Warrant Certificates and this Warrant Agent Agreement;

  

	 	(ii)	where a Warrant Exercise Notice or other document appears on its face to have been improperly completed or executed or some other irregularity in connection with the exercise of the
Warrants exists, the Warrant Agent will endeavor to inform the appropriate parties (including the person submitting such instrument) of the need for fulfillment of all requirements, specifying those requirements which appear to be unfulfilled;

  

	 	(iii)	inform the Company of and cooperate with and assist the Company in resolving any reconciliation problems between Warrant Exercise Notices received and delivery of Warrants to the
Warrant Agent’s account; 

  

	 	(iv)	advise the Company no later than one business day after receipt of a Warrant Exercise Notice, of (A) the receipt of such Warrant Exercise Notice and the number of Warrants exercised
in accordance with the terms and conditions of this Warrant Agent Agreement, (B) the instructions with respect to delivery of the shares of New Common Stock of the Company deliverable upon such exercise, subject to timely receipt from the Depositary
of the necessary information, and (C) such other information as the Company will reasonably require; and 

  

	 	(v)	subject to New Common Stock being made available to the Warrant Agent by or on behalf of the Company for delivery to the Depositary, liaise with the Depositary and endeavor to
effect such delivery to the relevant accounts at the Depositary in accordance with its requirements. 

  
 (f) All questions as to the validity, form and sufficiency (including time of receipt) of a Warrant exercise will be determined by the Company in its sole
discretion, which determination will be final and binding. The Warrant Agent will incur no liability for or in respect of such determination by the Company. The Company reserves the right to reject any and all Warrant Exercise Notices not in proper
form or for which any corresponding agreement by the Company to exchange would, in the opinion of the Company, be unlawful. Such determination by the Company will be final and binding on the Holders, absent manifest error. Moreover, the Company
reserves the absolute right to waive any of the conditions to the exercise of Warrants or defects in Warrant Exercise Notices with regard to any particular exercise of Warrants. The Company will be under no duty to give notice to the Holders of the
Warrants of any irregularities in any exercise of Warrants, nor will it incur any liability for the failure to give such notice. 
  

 - 10 - 

 (g) As soon as practicable after the exercise of any Warrant, the Company will issue, or otherwise
deliver, in authorized denominations to or upon the order of the Holder of the Warrant Certificates evidencing such Warrants, either: 
  

	 	(i)	if such Holder holds the Warrant being exercised through the Depositary’s book-entry transfer facilities, by credit to the Depositary for the account of such Holder or for the
account of a participant in the Depositary the number of Warrant Shares to which such Holder is entitled, in each case registered in such name and delivered to such account as directed in the Warrant Exercise Notice by such Holder or by the direct
participant in the Depositary through which such Holder is acting, or 

  

	 	(ii)	if such Holder holds the Warrants being exercised in the form of Definitive Warrant Certificates, by delivery to the address designated by such Holder in its Warrant Exercise Notice
of a physical certificate representing the number of Warrant Shares to which such Holder is entitled, in fully registered form, registered in such name or names as may be directed by such Holder. If less than all of the Warrants evidenced by a
Warrant Certificate surrendered upon the exercise of Warrants are exercised at any time prior to the date of expiration for the Warrants, a new Warrant Certificate or Certificates will be issued for the remaining number of Warrants evidenced by the
Warrant Certificate so surrendered, and the Warrant Agent is hereby authorized to countersign the required new Warrant Certificate or Certificates pursuant to the provisions of Section 5 and this Section 7. 

  
 (h) The Warrant Agent will keep copies of this Warrant Agent Agreement and
any notices given or received hereunder by or from the Company available for inspection by the Holders during normal business hours at its office. The Company will supply the Warrant Agent from time to time with such numbers of copies of this
Warrant Agent Agreement as the Warrant Agent may request. 
  
 SECTION 8. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the initial issuance of Warrant Shares upon the exercise of Warrants; provided that the Company will not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue of any new certificates evidencing the Warrants or any certificates for Warrant Shares in a name other than that of the registered Holder upon the exercise of Warrants, and
the Company or the Warrant Agent will not be required to issue or deliver such new certificates evidencing the Warrants or certificates for Warrant Shares unless or until the person or persons requesting the issuance thereof will have paid to the
Company the amount of such tax or will have established to the satisfaction of the Company that such tax has been paid. 
  
 SECTION 9. Mutilated or Missing Warrant Certificates. If any Warrant Certificate will be mutilated, lost, stolen or destroyed, the Company may in
its discretion issue and the Warrant Agent may countersign in exchange and substitution for, and upon cancellation of, the Warrant 

  

 - 11 - 

 
Certificate, if mutilated or in lieu of and substitution for the Warrant Certificate, if lost, stolen or destroyed, a new certificate of like tenor
evidencing an equal number of Warrants, but only upon receipt of evidence reasonably satisfactory to the Company and Warrant Agent of such loss, theft or destruction and indemnity and security therefor, if requested, also satisfactory to the Company
and the Warrant Agent. Applicants for such substitute Warrant Certificate will also comply with such other reasonable regulations and pay such other reasonable charges as the Company or Warrant Agent may prescribe. 
  
 SECTION 10. Reservation of Warrant Shares. The Company will at all
times reserve and keep available, free from preemptive rights, or any other actual contingent purchase rights of persons other than the Holders out of the aggregate of its authorized but unissued New Common Shares, for the purpose of enabling it to
satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the maximum number of New Common Shares which may then be deliverable upon the exercise of all outstanding Warrants. 
  
 The transfer agent for the New Common Stock (the “Transfer Agent”)
and every subsequent transfer agent for any shares of the Company’s capital stock issuable upon the exercise of any of the rights of purchase aforesaid will be irrevocably authorized and directed at all times to reserve such number of
authorized shares as will be required for such purpose. The Company will keep a copy of this Warrant Agent Agreement on file with the Transfer Agent and with every subsequent transfer agent for any shares of the Company’s capital stock issuable
upon the exercise of the rights of purchase represented by the Warrants. The Warrant Agent is hereby irrevocably authorized to requisition from time to time from such Transfer Agent the stock certificates required to honor outstanding Warrants upon
exercise thereof in accordance with the terms of this Warrant Agent Agreement. The Company will supply such Transfer Agent with duly executed certificates for such purposes. The Company will furnish such Transfer Agent a copy of all notices of
adjustments and certificates related thereto, if any, transmitted to each Holder of the Warrants pursuant to this Warrant Agent Agreement. 
  
 The Company covenants that all Warrant Shares which may be issued upon exercise of Warrants will be, upon payment or other satisfaction of the Exercise
Price and issuance thereof, fully paid, nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests with respect to the issue thereof. 
  
 SECTION 11. Fractional Interests. The Company will not be required to issue fractional Warrant Shares upon the
exercise of Warrants. If more than one Warrant will be presented for exercise at the same time by the Holder, the full number of Warrant Shares which will be issuable upon the exercise thereof will be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented. If any fraction of a Warrant Share would be issuable on the exercise of any Warrants as provided in Section 7, the actual distribution of Warrant Shares will reflect a rounding to
the nearest whole number of Warrant Shares to be issued (up or down), with half shares being rounded up. 
  
 SECTION 12. Merger, Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it
may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent will be a party, or any corporation succeeding to the business of the Warrant Agent, will be the 

  

 - 12 - 

 
successor to the Warrant Agent hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided
that such corporation would be eligible for appointment as a successor to the Warrant Agent under the provisions of Section 14. Any such successor warrant agent will promptly cause notice of its succession as Warrant Agent to be mailed (by first
class mail, postage prepaid) to each Holder at such Holder’s last address as shown on the register maintained by the Warrant Agent pursuant to this Warrant Agent Agreement. In case at the time such successor to the Warrant Agent will succeed to
the agency created by this Warrant Agent Agreement, and in case at that time any of the Warrant Certificates will have been countersigned but not delivered, any such successor to the Warrant Agent may adopt the countersignature of the original
Warrant Agent; and in case at that time any of the Warrant Certificates will not have been countersigned, any successor to the Warrant Agent may countersign such Warrant Certificates either in the name of the predecessor Warrant Agent or in the name
of the successor to the Warrant Agent; and in all such cases such Warrant Certificates will have the full force and effect provided in the Warrant Certificates and in this Warrant Agent Agreement. 
  
 In case at any time the name of the Warrant Agent will be changed and at such
time any of the Warrant Certificates will have been countersigned but not delivered, the Warrant Agent whose name has been changed may adopt the countersignature under its prior name, and in case at that time any of the Warrant Certificates will not
have been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name, and in all such cases such Warrant Certificates will have the full force and effect provided in the Warrant
Certificates and in this Warrant Agent Agreement. 
  
 SECTION 13.
Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Warrant Agent Agreement and the Warrant Certificate, in each case, upon the following terms and conditions, by all of which the Company and the Holders of
Warrants, by their acceptance thereof, will be bound: 
  
 (a) The
statements contained herein and in the Warrant Certificates will be taken as statements of the Company, and the Warrant Agent assumes no responsibility for the correctness of any of the same except such as describe the Warrant Agent or action taken
or to be taken by it. The Warrant Agent assumes no responsibility with respect to the distribution of the Warrant Certificates except as herein otherwise provided. 
  
 (b) The Warrant Agent will not be responsible for any failure of the Company to comply with any of the covenants contained
in this Warrant Agent Agreement or in the Warrant Certificates to be complied with by the Company. 
  
 (c) The Warrant Agent may consult at any time with counsel satisfactory to it (who may be counsel for the Company) and the Warrant Agent will incur no
liability or responsibility to the Company or to any Holder of any Warrant Certificate in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the opinion or the advice of such counsel, absent gross
negligence, bad faith or willful misconduct (each as determined by a final order, judgment, ruling or decree of a court of competent jurisdiction) in the selection and continued retention of such counsel and the reliance on such counsel’s
advice. 
  

 - 13 - 

 (d) The Warrant Agent will incur no liability or responsibility to the Company or to any Holder of any
Warrant Certificate for any action taken in reliance on any notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument believed by it to be genuine and to have been signed, sent or presented by the proper party
or parties. 
  
 (e) The Company agrees to pay to the Warrant Agent
reasonable compensation for all services rendered by the Warrant Agent in the execution of this Warrant Agent Agreement as more fully described on Exhibit D attached hereto. In addition, the Company agrees to indemnify the Warrant Agent and save it
harmless against any and all liabilities, including judgments, reasonable costs and reasonable counsel fees and expenses, for anything done or omitted by the Warrant Agent in the execution of this Warrant Agent Agreement except as a result of its
gross negligence, bad faith or willful misconduct (each as determined by a final order, judgment, ruling or decree of a court of competent jurisdiction). Notwithstanding the foregoing, the Company will not be responsible for any settlement made
without its written consent, which consent will not be unreasonably withheld. 
  
 (f) The Warrant Agent will be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the Company or one or more Holders of Warrant
Certificates will furnish the Warrant Agent with reasonable security and indemnity for any costs and expenses which may be incurred, but this provision will not affect the power of the Warrant Agent to take such action as it may consider proper,
whether with or without any such security or indemnity. All rights of action under this Warrant Agent Agreement or under any of the Warrants may be enforced by the Warrant Agent without the possession of any of the Warrant Certificates or the
production thereof at any trial or other proceeding relative thereto, and any such action, suit or proceeding instituted by the Warrant Agent will be brought in its name as Warrant Agent and any recovery of judgment will be for the ratable benefit
of the Holders of the Warrants, as their respective rights or interests may appear. 
  
 (g) The Warrant Agent, and any shareholder, affiliate, director, officer or employee thereof, may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Warrant Agent Agreement, or a shareholder, affiliate, director,
officer or employee of the Warrant Agent, as the case may be. Nothing herein will preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. 
  
 (h) The Warrant Agent will act hereunder solely as agent for the Company, and
its duties will be determined solely by the provisions hereof. The Warrant Agent will not be liable for anything which it may do or refrain from doing in connection with this Warrant Agent Agreement except for its own gross negligence, bad faith or
willful misconduct (each as determined by a final order, judgment, decree or ruling of a court of competent jurisdiction). 
  
 (i) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Warrant Agent Agreement. 
  

 - 14 - 

 (j) The Warrant Agent will not be under any responsibility in respect of the validity of this Warrant
Agent Agreement or the execution and delivery hereof (except the due and validly authorized execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant Certificate (except its due and validly authorized
countersignature thereof), nor will the Warrant Agent by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of the Warrant Shares to be issued pursuant to this Warrant Agent Agreement or any
Warrant Certificate or as to whether the Warrant Shares will when issued be validly issued, fully paid and nonassessable or as to the Exercise Price or the number of Warrant Shares issuable upon exercise of any Warrant. 
  
 (k) The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the Officers and to apply to the Officers for advice or instructions in connection with its duties, and such instructions will be full authorization and protection to the
Warrant Agent and the Warrant Agent will not be liable for any action taken, suffered to be taken, or omitted to be taken by it in good faith in accordance with instructions of the Officer or in good faith reliance upon any statement signed by any
one of the Officers with respect to any fact or matter (unless other evidence in respect thereof is herein specifically prescribed) which may be deemed to be conclusively proved and established by such signed statement. 
  
 (l) If the Warrant Agent will receive any notice or demand (other than notice
of or demand for exercise of Warrants) addressed to the Company by any Holder pursuant to the provisions of the Warrant Certificates, the Warrant Agent will promptly forward such notice or demand to the Company. 
  
 (m) No provision of this Warrant Agent Agreement will be construed to relieve
the Warrant Agent from liability for its own gross negligence, bad faith or willful misconduct. 
  
 SECTION 14. Resignation and Removal of Warrant Agent; Appointment of Successor. No resignation or removal of the Warrant Agent and no appointment
of a successor warrant agent will become effective until the acceptance of appointment by the successor warrant agent as provided herein. The Warrant Agent may resign its duties and be discharged from all further duties and liability hereunder
(except liability arising as a result of the Warrant Agent’s own gross negligence, bad faith or willful misconduct) after giving written notice to the Company. The Company may remove the Warrant Agent upon written notice, and the Warrant Agent
will thereupon in like manner be discharged from all further duties and liabilities hereunder, except as aforesaid. The Warrant Agent will, at the Company’s expense, mail (by first class mail, postage prepaid) to each Holder of a Warrant at his
last address as shown on the register of the Company maintained by the Warrant Agent a copy of said notice of resignation or notice of removal, as the case may be. Upon such resignation or removal, the Company will appoint in writing a new warrant
agent. If the Company will fail to make such appointment within a period of 20 days after it has been notified in writing of such resignation by the resigning Warrant Agent or after such removal, then the resigning Warrant Agent or the Holder of any
Warrant may apply to any court of competent jurisdiction for the appointment of a new warrant agent. Any new warrant agent, whether appointed by the Company or by such a court, will be a corporation doing business under the laws of the United States
or any state thereof, in good standing and having a 

  

 - 15 - 

 
combined capital and surplus of not less than $50,000,000. The combined capital and surplus of any such new warrant agent will be deemed to be the combined
capital and surplus as set forth in the most recent annual report of its condition published by such warrant agent prior to its appointment, provided that such reports are published at least annually pursuant to law or to the requirements of a
federal or state supervising or examining authority. After acceptance in writing of such appointment by the new warrant agent, it will be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as
the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it will be necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same will be done at the expense of the
Company and will be legally and validly executed and delivered by the resigning or removed Warrant Agent. Not later than the effective date of any such appointment, the Company will give notice thereof to the resigning or removed Warrant Agent.
Failure to give any notice provided for in this Section, however, or any defect therein, will not affect the legality or validity of the resignation of the Warrant Agent or the appointment of a new warrant agent, as the case may be. 
  
 SECTION 15. Notices to Company and Warrant Agent. Any notice or demand
authorized or required by this Warrant Agent Agreement to be given or made by the Warrant Agent or by the Holder of any Warrant Certificate to or on the Company will be sufficiently given or made when and if deposited in the mail, first class or
registered, postage prepaid, addressed (until another address is filed in writing by the Company with the Warrant Agent), as follows:

 SECTION 16. Entire Agreement. This Warrant
Agent Agreement constitutes the entire agreement and supersedes all other prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and may not be amended, except in a
writing signed by both of them. 
  
 SECTION 17. Supplements and
Amendments. The Company and the Warrant Agent may from time to time supplement or amend this Warrant Agent Agreement without the approval of any Holders of Warrant Certificates in order to cure any ambiguity or to correct or supplement any
provision contained herein which may be defective or inconsistent with any other provision herein, or to make any other provisions in regard to matters or questions arising hereunder which the Company and the Warrant Agent may deem necessary or
desirable and which will not in any way adversely affect the interests of the Holders of Warrant Certificates. Any amendment or supplement to this Warrant Agent Agreement that has a material effect on the interests of Holders will require the
written consent of Holders representing a majority of the then outstanding Warrants. The consent of each Holder of a Warrant affected will be required for any amendment pursuant to which the Exercise Price would be increased or the number of Warrant
Shares purchasable upon exercise of Warrants would be decreased. 
  
 SECTION 18. Successors. All the covenants and provisions of this Warrant Agent Agreement by or for the benefit of the Company or the Warrant Agent will bind and inure to the benefit of their respective successors and assigns
hereunder. 
  
 SECTION 19. Termination. This Warrant Agent
Agreement (other than any party’s obligations with respect to Warrants previously exercised and with respect to indemnification under Section 13) will terminate at 5:00 p.m., Eastern time, on the Expiration Date. Notwithstanding the foregoing,
this Warrant Agent Agreement will terminate on any earlier date when all Warrants have been exercised. 
  
 SECTION 20. Governing Law. This Warrant Agent Agreement and each Warrant Certificate issued hereunder will be deemed to be a contract made under
the laws of the State of Ohio and for all purposes will be construed in accordance with the internal laws of said state, without regard to principles of conflicts of law of such state. 
  

 - 17 - 

 SECTION 21. Benefits of this Warrant Agent Agreement. Nothing in this Warrant Agent Agreement will
be construed to give to any person or corporation other than the Company, the Warrant Agent and the Holders of the Warrant Certificates any legal or equitable right, remedy or claim under this Warrant Agent Agreement; and this Warrant Agent
Agreement will be for the sole and exclusive benefit of the Company, the Warrant Agent and the Holders of the Warrant Certificates. 
  
 SECTION 22. Holder Not Deemed a Shareholder. Prior to the exercise of the Warrants, no Holder of a Warrant Certificate, as such, will be entitled
to any rights of a shareholder of the Company, including the right to receive dividends or subscription rights, the right to vote, to consent, to exercise any preemptive right, to receive any notice of meetings of shareholders for the election of
directors of the Company or any other matter or to receive any notice of any proceedings of the Company, except as may be specifically provided for herein. The Holders of the Warrants are not entitled to share in the assets of the Company in the
event of the liquidation, dissolution or winding up of the Company’s affairs. 
  
 SECTION 23. Counterparts. This Warrant Agent Agreement may be executed in any number of counterparts, and each of such counterparts (including facsimile copies) will for all purposes be deemed to be an
original, and all such counterparts will together constitute but one and the same instrument. 
  
 SECTION 24. Severability. If any part of this Warrant Agent Agreement will be held to be invalid or unenforceable by any court, or regulatory agency or body, such invalidity or unenforceability will attach only
to such part and will not affect the validity or enforceability of the rest of this Warrant Agent Agreement. Furthermore, in lieu of any such invalid or unenforceable provision or condition, the parties hereto intend that there will be added as a
part of this Warrant Agent Agreement a provision as similar in terms and commercial effect to such invalid or unenforceable provision as may be possible and be valid and enforceable.

 Warrants      

  
 This Warrant
Certificate certifies that
                                         or its
registered assigns, is the registered holder of Warrants (the “Warrants”) to purchase common stock, par value $.01 (the “Common Stock”), of Oglebay Norton Company, an Ohio corporation (the “Company”). These Warrants
expire at 5:00 p.m., Eastern time, on March 2, 2005 (the “Expiration Date”). Each Warrant entitles the holder thereof to purchase one-tenth (1/10th) of a fully paid and nonassessable share of Common Stock, at the exercise price of $10.00
per share of Common Stock (the “Exercise Price”). The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering (a) this Warrant Certificate evidencing the Warrants to be exercised, (b) the form of election
to purchase on the reverse of such certificate duly filled in and signed, which signature must be guaranteed by an Eligible Guarantor Institution pursuant to SEC Rule 17Ad-15, if appropriate, and (c) payment to the Warrant Agent, for the account of
the Company, of the amount equal to the Exercise Price multiplied by the number of shares of Common Stock (the “Exercise Amount”) of which such Warrants are then exercised. Payment of the Exercise Amount will be made to the Warrant Agent
by certified check, official bank check, express money order, payable to the order of the Company, or by wire transfer in immediately available funds. The Warrants are exercisable only subject to the conditions set forth herein and in the Warrant
Agent Agreement referred to on the reverse hereof. The Warrants entitle the holder thereof to purchase at the Exercise Price one share of Common Stock for each ten (10) Warrants held. Except in the case where a holder is exercising all Warrants then
held, shares of Common Stock (the “Warrant Shares”) may be purchased only pursuant to the exercise of Warrants in integral multiples of ten (10). No fractions of a Warrant Share will be issued upon the exercise of any Warrants. If any
fraction of a Warrant Share would be issuable on the exercise of all Warrants then held by a holder, the number of Warrant Shares issuable to such holder pursuant to such Warrants will reflect a rounding to the nearest whole number of Warrant Shares
to be issued (up or down), with half shares being rounded up. The Warrants are transferable; provided, however, that any Warrants held by an affiliate of the Company may generally only be resold pursuant to a valid exemption under the Securities Act
of 1933. The Warrants are exercisable by the subsequent holder thereof pursuant to the terms and conditions provided in the Warrant Agent Agreement. 

 These Warrants are immediately exercisable. No Warrants may be exercised after 5:00 p.m., Eastern time,
on the Expiration Date, and to the extent not exercised by such time, such Warrants will become void and of no value. 
  
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS WARRANT CERTIFICATE SET FORTH ON THE REVERSE HEREOF AND SUCH FURTHER PROVISIONS WILL FOR ALL
PURPOSES HAVE THE SAME EFFECT AS THOUGH FULLY SET FORTH AT THIS PLACE. 
  
 This Warrant Certificate will not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agent Agreement. 
  
 This Warrant Certificate will be governed by and construed in accordance with the internal laws of the State of Ohio. 
  
 IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be
signed by its President and Chief Executive Officer and by its Secretary, each by a signature or a facsimile thereof.

 [FORM OF WARRANT CERTIFICATE] 
  
 [REVERSE] 
  
 The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants expiring on the Expiration Date entitling the holder on
exercise to receive shares of Common Stock of the Company, and are issued or to be issued pursuant to a Warrant Agent Agreement dated as of January 28, 2005 (the “Warrant Agent Agreement”), duly executed and delivered by the Company to
Wells Fargo Bank, National Association, as warrant agent (the “Warrant Agent”), which Warrant Agent Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the
rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the registered holders or registered holder) of the Warrants.
A copy of the Warrant Agent Agreement may be obtained by the holder hereof upon written request to the Company. Capitalized terms used herein without definition will have the meanings ascribed to them in the Warrant Agent Agreement. 
  
 In the event that upon any exercise of Warrants evidenced hereby the number
of Warrants exercised will be less than the total number of Warrants evidenced hereby, there will be issued to the holder hereof or his assignee a new Warrant Certificate evidencing the number of Warrants not exercised and the number of Warrant
Shares remaining to be exercised. 
  
 Warrant Certificates, when
surrendered at the office of the Warrant Agent by the registered holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agent
Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
  
 Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent, a new
Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants will be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant
Agent Agreement. 
  
 The Company and the Warrant Agent may deem
and treat the registered holder(s) thereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the
holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent will be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder
of the Company. 
  
 The Company will be subject to the Jones Act
as long as it owns and operates its Great Lakes shipping business. In order to ensure that the Company is determined to be a United States citizen as defined under the Jones Act, the Company’s second amended and restated articles of
incorporation contain restrictions on the ownership of its capital stock by non-United States citizens. Therefore, Common Stock received by an exercising holder of Warrants who is a foreigner may be subject to certain transfer restrictions to
maintain compliance with the Jones Act. 

 EXHIBIT A-2 
  
 [FORM OF GLOBAL WARRANT CERTIFICATE] 
  
 [FACE] 
  
 This Global Warrant Certificate is held by The Depository Trust Company (the “Depositary”) or its nominee in custody for the benefit of the
beneficial owners hereof, and is not transferable to any person under any circumstances except that (a) this Global Warrant Certificate may be exchanged in whole but not in part pursuant to Section 6(c) of the Warrant Agent Agreement, (b) this
Global Warrant Certificate may be delivered to the Warrant Agent for cancellation pursuant to Section 6(g) of the Warrant Agent Agreement and (c) this Global Warrant Certificate may be transferred to a successor Depositary with the prior written
consent of the Company. 
  
 Unless this Global Warrant Certificate
is presented by an authorized representative of the Depositary to the Company or the Warrant Agent for registration of transfer, exchange or payment and any certificate issued is registered in the name of Cede & Co. or such other entity as is
requested by an authorized representative of the Depositary (and any payment hereon is made to Cede & Co. or to such other entity as is required by an authorized representative of the Depositary), any transfer, pledge or other use hereof for
value or otherwise by or to any person is wrongful because the registered owner hereof, Cede & Co., has an interest herein. 
  
 Transfers of this Global Warrant Certificate will be limited to transfers in whole, but not in part, to nominees of the Depositary or to a successor
thereof or such successor’s nominee, and transfers of portions of this Global Warrant Certificate will be limited to transfers made in accordance with the restrictions set forth in Section 6 of the Warrant Agent Agreement. 
  
 No registration of transfer of the securities issuable pursuant to this
Global Warrant Certificate will be recorded on the books of the Company until such provisions have been complied with.

 This Warrant
Certificate certifies that
                                         or its

expire at 5:00 p.m., Eastern time, on March 2, 2005 (the “Expiration Date”). Each Warrant entitles the holder thereof to purchase 

 
one-tenth (1/10th) of a fully paid and nonassessable share of Common Stock, at the exercise price of $10.00 per share of Common Stock (the “Exercise
Price”). The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering (a) this Warrant Certificate evidencing the Warrants to be exercised, (b) the form of election to purchase on the reverse of such
certificate duly filled in and signed, which signature must be guaranteed by an Eligible Guarantor Institution pursuant to SEC Rule 17Ad-15, if appropriate and (c) payment to the Warrant Agent, for the account of the Company, of the amount equal to
the Exercise Price multiplied by the number of shares of Common Stock (the “Exercise Amount”) of which such Warrants are then exercised. Payment of the Exercise Amount will be made to the Warrant Agent by certified check, official bank
check, express money order, payable to the order of the Company, or by wire transfer in immediately available funds. The Warrants are exercisable only subject to the conditions set forth herein and in the Warrant Agent Agreement referred to on the
reverse hereof. The Warrants entitle the holder thereof to purchase at the Exercise Price one share of Common Stock for each ten (10) Warrants held. Except in the case where a holder is exercising all Warrants then held, shares of Common Stock (the
“Warrant Shares”) may be purchased only pursuant to the exercise of Warrants in integral multiples of ten (10). No fractions of a Warrant Share will be issued upon the exercise of any Warrants. If any fraction of a Warrant Share would be
issuable on the exercise of all Warrants then held by a holder, the number of Warrant Shares issuable to such holder pursuant to such Warrants will reflect a rounding to the nearest whole number of Warrant Shares to be issued (up or down), with half
shares being rounded up. The Warrants are transferable; provided, however, that any Warrants held by an affiliate of the Company may generally only be resold pursuant to a valid exemption under the Securities Act of 1933. The Warrants are
exercisable by the subsequent holder thereof pursuant to the terms and conditions provided in the Warrant Agent Agreement. 
  
 These Warrants are immediately exercisable. No Warrants may be exercised after 5:00 p.m., Eastern time, on the Expiration Date, and to the extent not
exercised by such time, such Warrants will become void and of no value. 
  
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS WARRANT CERTIFICATE SET FORTH ON THE REVERSE HEREOF AND SUCH FURTHER PROVISIONS WILL FOR ALL PURPOSES HAVE THE SAME EFFECT AS THOUGH FULLY SET FORTH AT THIS PLACE. 
  
 This Warrant Certificate will not be valid unless countersigned by the
Warrant Agent, as such term is used in the Warrant Agent Agreement. 
  
 This Warrant Certificate will be governed by and construed in accordance with the internal laws of the State of Ohio. 

 IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be signed by its President and
Chief Executive Officer and by its Secretary, each by a signature or a facsimile thereof.

 The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants expiring on the Expiration Date entitling the holder on
exercise to receive shares of Common Stock of the Company, and are issued or to be issued pursuant to a Warrant Agent Agreement dated as of January 28, 2005 (the “Warrant Agent Agreement”), duly executed and delivered by the Company to

rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the registered holders or registered holder) of the Warrants.
A copy of the Warrant Agent Agreement may be obtained by the holder hereof upon written request to the Company. Capitalized terms used herein without definition will have the meanings ascribed to them in the Warrant Agent Agreement. 
  
 In the event that upon any exercise of Warrants evidenced hereby the number
of Warrants exercised will be less than the total number of Warrants evidenced hereby, there will be issued to the holder hereof or his assignee a new Warrant Certificate evidencing the number of Warrants not exercised and the number of Warrant
Shares remaining to be exercised. 
  
 Warrant Certificates, when
surrendered at the office of the Warrant Agent by the registered holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agent
Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
  
 Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent, a new
Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants will be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant
Agent Agreement. 
  
 The Company and the Warrant Agent may deem
and treat the registered holder(s) thereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the
holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent will be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder
of the Company. 
  
 The Company will be subject to the Jones Act
as long as it owns and operates its Great Lakes shipping business. In order to ensure that the Company is determined to be a United States citizen as defined under the Jones Act, the Company’s second amended and restated articles of
incorporation contain restrictions on the ownership of its capital stock by non-United States citizens. Therefore, Common Stock received by an exercising holder of Warrants who is a foreigner may be subject to certain transfer restrictions to
maintain compliance with the Jones Act.

DETAILS. 

 INSTRUCTIONS TO SUBSTITUTE FORM W-9 
  
 Federal income tax law generally requires that a Warrant holder exercising its Warrants for Warrant Shares must provide the
Company (as payor) with such holder’s correct Taxpayer Identification Number (“TIN”) on Substitute Form W-9 above or otherwise establish a basis for exemption from backup withholding. If such holder is an individual, the TIN is his or
her social security number. If the Company is not provided with the current TIN or an adequate basis for an exemption, such holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, the holders of the Warrant
Shares may be subject to backup withholding on all reportable payments made after such exercise. The backup withholding rate is 28%. 
  
 Certain holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting
requirements. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (the “W-9 Guidelines”) for additional instructions. 
  
 Under the federal income tax laws, payments that may be made by the Company on account of Warrant Shares issued pursuant to
the exercise of the Warrants may be subject to backup withholding at the rates listed above. To prevent backup withholding, each exercising holder of Warrants must provide its correct TIN by completing the “Substitute Form W-9” set forth
above, certifying that the TIN provided is correct (or that such holder is awaiting a TIN) and that (i) the holder is exempt from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service that such holder is subject
to a backup withholding as a result of a failure to report all interest or dividends or (iii) the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the exercising holder of Warrants is a
nonresident alien or foreign entity not subject to backup withholding, such holder must give the Company a completed Form W-8, Certificate of Foreign Status. These forms may be obtained from the Warrant Agent. If the Warrants are in more than one
name or are not in the name of the actual owner, such holder should consult the W-9 Guidelines for information on which TIN to report. If such holder does not have a TIN, such holder should consult the W-9 Guidelines for instructions on applying for
a TIN, check the box in Part 2 of the Substitute Form W-9, write “applied for” in lieu of its TIN and complete the Certificate of Awaiting Taxpayer Identification Number. Note: checking this box or writing “applied for” on the
form means that such holder has already applied for a TIN or that such holder intends to apply for one in the near future. If a holder checks the box in Part 2 of the Substitute Form W-9 or writes “applied for” on that form, backup
withholding at the applicable rate will nevertheless apply to all reportable payments made to such holder. If such a holder furnishes its TIN to the Company within 60 days, however, any amounts so withheld shall be refunded to such holder. If,
however, the holder has not provided the Company with its TIN within such 60-day period, the Company will remit such previously retained amounts to the IRS as backup withholding. 
  
 Backup withholding is not an additional federal income tax. Rather, the Federal income tax liability of persons subject to
backup withholding will be reduced by the amount of tax withheld. If withholding results in overpayment of taxes, a refund may be obtained from the Internal Revenue Service.

 WARRANT AGENT COMPENSATION AND FEESRegistration Rights Agreement, dated as of January 31, 2005

 Exhibit 4.2 
  

REGISTRATION RIGHTS AGREEMENT 
  
 This Registration Rights Agreement (this “Agreement”), dated as of January 31, 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 $51,392,000 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 $33,608,000 of Preferred Shares consisting of (i) $26,288,800 of Preferred Shares representing the Noteholders’ Basic Commitment Amount (as defined in the Commitment Agreement), (ii) $2,319,200 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 27, 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 
  
 (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 

  

 - 2 - 

 
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. 
  
 (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, 

  

 - 3 - 

 
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 1.2 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 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 

  

 - 4 - 

 
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 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

  

 - 5 - 

 
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. 
  
 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 

  

 - 6 - 

 
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 mailed or so
delivered as addressed as follows:
