     Senior Notes shall be made without set off or counterclaim, directly by
     wire transfer to the accounts designated, respectively, in writing by the
     Purchasers, without any presentment or notation of payment, except that
     prior to any transfer of any Senior Note the holder thereof shall endorse
     on such Senior Note a record of the date to which interest has been paid
     and all payments made on account of principal of such Senior Note. All
     payments and prepayments of principal of and interest on the Senior Notes

     endorsement of such PIK Interest, issue to such holder additional Senior
     Notes evidencing the PIK Interest paid on the Senior Notes held by such
     Noteholder, in each case, promptly upon the request of such holder, all of
     which shall be made, issued and otherwise effected in accordance with the

     had been imposed upon the Company. The Company will deliver promptly to the
     Noteholders certificates or other valid vouchers for all taxes or other
     charges deducted from or paid with respect to payments made by the Company
     hereunder or under such other Senior Notes Document.

     the Company will pay the principal amount of the Senior Notes then

     of the Company to make the redemption required by the preceding sentence.
     The Company shall be required to redeem the Senior Notes in two equal
     installments in the amount of $37,500,000, which shall be paid on each of

     written notice setting forth in reasonable detail the facts and

     by the Company or any Subsidiary, as applicable, shall constitute an
     irrevocable offer by the Company to redeem such portion of the Senior Notes
     held by the Noteholder as may be redeemed at par with 50% of such Excess
     Net Proceeds, subject to the rights of all Noteholders to participate in

     shall furnish to each Noteholder written notice setting forth in reasonable
     detail the facts and circumstances relating thereto, including, without
     limitation, the intended or proposed use of such Excess Net Proceeds. On
     the earlier to occur of (i) the actual reinvestment of the Excess Net
     Proceeds as permitted hereunder and (ii) the 180/th/ day following the
     Company's or any Subsidiary's first possession of the Excess Net Proceeds,
     the Company shall furnish to each

                                       23



     Noteholder written notice, which notice either shall set forth in
     reasonable detail the facts and circumstances of the actual use of such
     Excess Net Proceeds on or prior to such date or state that such Excess Net
     Proceeds have not been reinvested as permitted hereunder. Unless such
     Excess Net Proceeds actually are used (in accordance with the terms hereof)
     solely for the purpose of rebuilding, replacing or restoring the Property
     the damage or destruction of which gave rise to the payment of such Excess
     Net Proceeds within 180 days of receipt of such Excess Net Proceeds, the
     possession of such Excess Net Proceeds by the Company or any Subsidiary, as
     applicable, shall constitute an irrevocable offer by the Company to redeem
     such portion of the Senior Notes held by such Noteholder as may be redeemed
     at par with 100% of such Excess Net Proceeds, subject to the rights of all
     Noteholders to participate in the transaction on a pari passu basis.

                (d)  As soon as possible, and in any event within 30 Business
     Days prior to the date on which a Company or any Subsidiary first possesses
     Excess Net Proceeds from any Asset Sale (other than Proceeds from a sale
     and leaseback transaction if such Proceeds, together with the Proceeds of
     all other sale and leaseback transactions of the Company and/or any of its
     Subsidiaries consummated on or after the Closing Date, do not exceed
     $5,000,000) then, in each such case, the Company shall furnish to each
     Noteholder written notice setting forth in reasonable detail the facts and
     circumstances relating to such Asset Sale, including, without limitation,
     the intended or proposed use of such Excess Net Proceeds. On the earlier to
     occur of (i) the actual reinvestment of the Excess Net Proceeds permitted
     hereunder and (ii) the 180/th/ day following the Company's or any
     Subsidiary's first possession of the Excess Net Proceeds, the Company shall
     furnish to each Noteholder written notice, which notice either shall set
     forth in reasonable detail the facts and circumstances of the actual use of
     such Excess Net Proceeds on or prior to such date or state that such Excess
     Net Proceeds have not been reinvested as permitted hereunder. Unless such
     Excess Net Proceeds are actually reinvested in the business of the Company
     and its Subsidiaries in accordance with the terms of this Agreement within
     180 days of their receipt, the possession of such Excess Net Proceeds by
     the Company or any Subsidiary, as applicable, shall constitute an
     irrevocable offer by the Company to redeem such portion of the Senior Notes
     held by such Noteholder as may be redeemed with 100% of such Excess Net
     Proceeds at par, subject to the rights of all Noteholders to participate in
     the transaction on a pari passu basis.

                (e)  Following receipt of any offer to redeem the Senior Notes
     (or a portion thereof) under clauses (b), (c) or (d) of this Section 2.5.1
     (the date of which shall be the date of receipt of the applicable Excess
     Net Proceeds in the case of clause (b) above and either the date of
     receipt, or the 181/st/ date following receipt, as applicable, of such
     Excess Net Proceeds, in the case of clauses (c) and (d) above), each
     Noteholder shall advise the Company, by written notice, within 20 calendar
     days after actual receipt of written notice of such offer, as to whether it
     desires to sell all or any of the Senior Notes held by it (in integral
     multiples of $100,000), specifying the principal amount of the Senior Notes
     to be redeemed by the Company. If a Noteholder accepts such offer but does
     not specify an amount it wishes to have redeemed, such Noteholder will be
     deemed

                                       24



     to have elected to have redeemed all of the Senior Notes held by it, or, if
     such amount is less, such Noteholder's pro rata share of the Excess Net
     Proceeds then available to redeem Senior Notes. If a Noteholder fails to
     respond to such offer by the Company within the 20-day acceptance period,
     such offer shall expire in accordance with its terms. The Company shall
     redeem Senior Notes elected to be redeemed by the holders thereof under
     Section 2.5.2 within 10 Business Days of the expiration of such acceptance
     period.

          2.5.2 Optional Redemptions. In addition to the redemption of the
Senior Notes required under Section 2.5.1, the Company may at any time on and
after the second anniversary of the Closing Date voluntarily redeem the Senior
Notes in whole, or in part (in a minimum amount of at least $5,000,000 and
integral multiples of $500,000), together with all accrued and unpaid interest
on the amount so redeemed through the date of redemption, at a redemption price
equal to the sum of the principal amount to be redeemed plus the prepayment
premium indicated below corresponding to the period in which the redemption
occurs (such premium, the "Prepayment Premium").

                    Period                               Prepayment Premium

     October 25, 2004 through October 25, 2005       6% of principal amount to
                                                            be redeemed

     October 25, 2005 to October 25, 2006               4% of the principal
                                                       amount to be redeemed

     October 25, 2006 to October 25, 2007               2% of the principal
                                                       amount to be redeemed

     After October 25, 2007                                     None

          2.5.3 Notice of Redemptions; Pro Rata Redemptions. Written notice of
any redemption pursuant to Section 2.5.1 or Section 2.5.2 shall be given to all
Noteholders at least 30 Business Days prior to the date of any such redemption.
Each redemption of the Senior Notes pursuant to Sections 2.5.1 and 2.5.2 shall
be made so that all outstanding Senior Notes then held by each holder (or, in
the case of any redemption under Section 2.5.1(b) through (d), the Senior Notes
held by each holder thereof accepting the Company's offer as provided in Section
2.5.1(e)) shall be redeemed in a principal amount which shall bear the same
ratio to the total unpaid principal amount being redeemed on all such Senior
Notes as the unpaid principal amount of the Senior Notes then held by such
holder bears to the aggregate unpaid principal amount of such Senior Notes.

          2.5.4 Mandatory Repurchase of Senior Notes.

                (a)  As soon as possible, and in any event within 30 Business
     Days prior to the occurrence of a Mandatory Repurchase Event, the Company
     shall furnish to

                                       25



     each Noteholder written notice setting forth in reasonable detail the facts
     and circumstances underlying such Mandatory Repurchase Event. The
     occurrence of any such Mandatory Repurchase Event shall constitute an
     irrevocable offer by the Company to purchase all of the Senior Notes held
     by such Noteholder, for the redemption price specified in Section 2.5.2,
     or, in the case of a Mandatory Repurchase Event occurring prior to October
     25, 2004, for a redemption price equal to the Make Whole Amount, in each
     case, on the occurrence of such Mandatory Repurchase Event and together
     with all accrued and unpaid interest on the amount so purchased through the
     date of purchase.

                (b)  Following receipt of any offer to purchase the Senior Notes
     under this Section 2.5.4, each Noteholder shall advise the Company, by
     written notice, within 10 Business Days after receipt of such offer, as to
     whether it desires to sell all or any of the Senior Notes held by it (in
     integral multiples of $500,000), specifying the principal amount of the
     Senior Notes to be sold by it. If a Noteholder accepts such offer but does
     not specify an amount it wishes to receive, such Noteholder will be deemed
     to have elected to sell all of the Senior Notes held by it. If a Noteholder
     fails to respond to such offer by the Company within the 10 Business Day
     acceptance period, such offer shall expire in accordance with its terms.

          2.5.5 No Other Acquisition of Senior Notes. The Company will not and
will not permit any Affiliate to purchase, redeem, prepay, tender for or
otherwise acquire, directly or indirectly, any of the outstanding Senior Notes
except upon the repurchase or prepayment of the Senior Notes in accordance with
the other terms of this Section 2.5. The Company will promptly cancel all Senior
Notes acquired by it or any of its Affiliates pursuant to any purchase,
redemption, prepayment or tender for the Senior Notes pursuant to any provision
of this Agreement or otherwise and no Senior Notes may be issued in substitution
or exchange for any such Senior Notes.

     2.6  Default Rate of Interest. If an Event of Default has occurred and is
continuing, from and after the date such Event of Default has occurred the
entire outstanding unpaid principal balance of the Senior Notes and any unpaid
interest from time to time in default shall bear interest, payable on demand, at
the applicable Interest Rate plus 2% per annum, or such lower rate as then may
be the maximum rate permitted by Applicable Law; provided, however, that upon
the cessation or cure of such Event of Default, if no other Event of Default is
then continuing, the Senior Notes shall again bear interest at the applicable
Interest Rate as set forth in Section 2.1.

     2.7  Maximum Legal Rate of Interest. Nothing in this Agreement or in the
Senior Notes shall require the Company to pay interest at a rate in excess of
the maximum rate permitted by Applicable Law.

     2.8  Payment on Non-Business Days. Whenever any payment to be made shall be
due on a day which is not a Business Day, such payment may be made on the next
succeeding

                                       26



Business Day, and such extension of time shall in such case be included in the
computation of payment of interest due.

     2.9  Transfer and Exchange of Senior Notes. The Company shall keep a
register in which it shall provide for the registration of the Senior Notes and
the registration of transfers of Senior Notes. The holder of any Senior Note
may, prior to maturity or prepayment thereof, surrender such Senior Note at the
principal office of the Company for transfer or exchange. Any holder desiring to
transfer or exchange any Senior Note shall first notify the Company in writing
at least five days in advance of such transfer or exchange. Within a reasonable
time after such notice to the Company from a holder of its intention to make
such exchange and without expense (other than transfer taxes, if any) to such
holder, the Company shall issue in exchange therefor another Senior Note in the
same aggregate principal amount or if requested by the holder in denominations
of $100,000 and multiples thereof, except in the case of a Senior Note for the
balance of the aggregate amount of the Senior Note so transferred, as of the
date of such issuance, as the unpaid principal amount of the Senior Note so
surrendered and having the same maturity and rate of interest, containing the
same provisions and subject to the same terms and conditions as the Senior Note
so surrendered (provided that no minimum shall apply to a liquidating
distribution of Senior Notes to investors in a Noteholder and any Senior Notes
so distributed may be subsequently transferred by such investor and its
successors in the original denomination thereof without further restriction).
Each new Senior Note shall be made payable to such Person or Persons, or
assigns, as the holder of such surrendered Senior Note may designate, and such
transfer or exchange shall be made in such a manner that no gain or loss of
principal or interest shall result therefrom. The Company shall have no
obligation hereunder or under any Senior Note to any Person other than the
registered holder of each such Senior Note. Notwithstanding anything to the
contrary contained herein, (a) no Noteholder shall be permitted to transfer any
of its Senior Notes unless such Noteholder's transferee has agreed in writing to
be bound by the terms of this Agreement and the other Senior Notes Documents to
which such Noteholder is a party, including the representations and warranties
set forth in Section 4.1 hereof, and (b) so long as no Default has occurred and
is continuing, no Noteholder shall be permitted to transfer any of its Senior
Notes to any Person that is a Restricted Transferee without the prior written
consent of the Company.

     2.10 Replacement of Senior Notes. Upon receipt of evidence satisfactory to
the Company of the loss, theft, destruction or mutilation of any Senior Note
and, if requested in the case of any such loss, theft or destruction, upon
delivery of an indemnity bond or other agreement or security reasonably
satisfactory to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of such Senior Note the Company will issue a new
Senior Note of like tenor and amount and dated the date to which interest has
been paid, in lieu of such lost, stolen, destroyed or mutilated Senior Note;
provided, however, if any Senior Note of which a Noteholder, its nominee, or any
of its partners is the holder is lost, stolen or destroyed, the affidavit of an
authorized partner or officer of the holder setting forth the circumstances with
respect to such loss, theft or destruction shall be accepted as satisfactory
evidence thereof, and no indemnification bond or other security shall be
required as a condition to the execution and delivery by the Company of a new
Senior Note in replacement of such lost,

                                       27



stolen or destroyed Senior Note other than the holders written agreement to
indemnify the Company.

     2.11 Ranking. The Senior Notes Obligations shall be secured obligations of
the Company and each of the Guarantors. The Senior Notes Obligations and the
rights and remedies of the Noteholders under the Senior Notes Documents shall
rank pari passu in right of payment with the Company's and each of the
Guarantors' existing and future senior indebtedness, including, without
limitation, the Syndicated Debt, and senior to the Company's and each of the
Guarantors' existing or hereafter arising Subordinated Debt (and any other
subordinated Indebtedness), including, without limitation, the Subordinated
Notes. The Liens granted by the Company and the Guarantors to the Noteholders
under the Security Documents shall rank junior to the Liens granted by the
Company and the Guarantors to the Agent and the Banks on the terms and
conditions of, and as otherwise provided in, the Intercreditor Agreement.
Without limiting the foregoing, the Senior Notes Obligations will and shall be
for all purposes (a) "Senior Indebtedness", and "Guaranteed Senior
Indebtedness," in the case of the Guaranteed Obligations, (each as defined in
the Subordinated Notes Indenture), (b) refinancing of "Obligations" and
"Indebtedness" under the "Senior Credit Facility" (each, as defined in the
Subordinated Notes Indenture), (c) "Indebtedness" under the "Senior Credit
Facility" (each as defined in the Subordinated Notes Indenture, and (d)
"Designated Senior Indebtedness" (as defined in the Subordinated Notes
Indenture).

     2.12 Structuring and Financing Fees. The Company hereby agrees to pay each
Purchaser or designee such Purchaser's pro rata share (based on the proportion
that the Senior Notes purchased by such Purchaser bears to the total Senior
Notes, in each case, on the Closing Date) of a structuring and financing fee
equal to 1.0% of the original principal amount of the Senior Notes, and such
fees shall be in addition to the amounts required to be paid pursuant to Section
3.2(e). At the option of Purchaser (with respect to such Purchaser) by notice to
the Company, such fee may be paid by each Purchaser (or the applicable
Purchaser) deducting such Purchaser's pro rata share of such fee from the
purchase price of the Senior Notes purchased by such Purchaser.

     availability of the remedy of specific performance or injunctive relief is
     subject to the discretion of the court before which any proceeding therefor
     may be brought.

               (b)  Such Purchaser is acquiring the Senior Notes for its own
     account, and not as nominee or agent.

               (c)  The Senior Notes are being and will be acquired for the
     purpose of investment and not with a view to distribution or resale thereof
     in violation of the securities laws; subject, nevertheless, to the
     condition that, except as otherwise provided herein and subject to
     compliance with applicable securities laws, the disposition of the property
     of such Purchaser shall at all times be within its control. Such Purchaser
     was not formed solely for the purpose of making an investment in the
     Company or its Subsidiaries. Such Purchaser is an "accredited investor" as
     that term is defined in Regulation D of the Securities Act with such
     knowledge and experience in financial and business matters as are necessary
     in order to evaluate the merits and risks of an investment in the Senior
     Notes.

               (d)  Such Purchaser understands that it must bear the economic
     risk of its investment for an indefinite period of time because the Senior
     Notes are not, and will

                                       32



     not be, registered under the Securities Act or any applicable state
     securities laws, except as may be provided in this Agreement, and may not
     be resold unless subsequently registered under the Securities Act and such
     other laws or unless an exemption from such registration is available. Such
     Purchaser acknowledges that, in issuing the Senior Notes, the Company is
     relying on the representations and warranties of such Purchaser in this
     Section 4.1.

               (e)  No Person has or will have, as a result of the transactions
     contemplated by this Agreement, any rights, interest or valid claim against
     or upon the Company or any of its Subsidiaries for any commission, fee or
     other compensation as a finder or broker because of any act or omission by
     such Purchaser or any agent of such Purchaser.

               (f)  Such Purchaser hereby acknowledges that the Senior Notes
     (unless no longer required in the opinion of counsel, which opinion and
     counsel shall be reasonably satisfactory to the Company, it being agreed
     that Goodwin Procter LLP shall be satisfactory) shall bear a legend
     substantially in the following form:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS AND MAY NOT
          BE SOLD OR TRANSFERRED WITHOUT COMPLIANCE WITH THE REGISTRATION OR
          QUALIFICATION PROVISIONS OF APPLICABLE FEDERAL AND STATE SECURITIES
          LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

The acquisition by each such Purchaser of the Senior Notes shall constitute a
confirmation by such Purchaser of the foregoing representations and warranties
made by such Purchaser.

                   ARTICLE V - REPRESENTATIONS AND WARRANTIES

     The Company represents and warrants to the Purchasers (and each of them) as
of the Closing Date as follows (which representations and warranties shall
survive the Closing), after giving effect to the transactions contemplated by
this Agreement and the other Senior Notes Documents:

     5.1  Senior Notes constitute Senior Indebtedness. The Senior Notes (and
each of them) and the other Senior Notes Obligations constitute, and shall
constitute at all times until repurchase or redemption thereof in accordance
with the terms of this Agreement, (a) "Senior Indebtedness" (and "Guaranteed
Senior Indebtedness" in the case of the Guaranteed Obligations) and "Designated
Senior Indebtedness" of the Company and the Guarantors, and (b) "Indebtedness"
under the "Senior Credit Facility", in each case as such terms are defined in
the Subordinated Notes Indenture. The Liens granted under the Security Documents
constitute, and at all times that any Senior Note or other Senior Notes
Obligation shall be outstanding, shall constitute, "Permitted Liens" under (and
as defined in) the Subordinated Notes Indenture.

                                       33

Organizational Documents of, or any material agreement or other material
instrument (including, without limitation, any of the Syndicated Facility
Documents, Subordinated Note Indenture or the Subordinated Notes) binding upon,
the Company or any of its Subsidiaries. The purchase of the Senior Notes is not
subject to preemptive or other similar statutory or contractual rights.

          5.2.3  Enforceability. The execution and delivery of this Agreement
and the other Senior Notes Documents to which the Company or any of its

except to the extent that availability of the remedy of specific performance or
injunctive relief is subject to the discretion of the court before which any
proceeding therefor may be brought.

owned by others in compliance with local law requirements), beneficially and of
record, free and clear of all liens, encumbrances, restrictions (other than
those under applicable securities laws) and claims of every kind. All the
outstanding shares of Capital Stock or other equity interests of each of the

outstanding on the date of this Agreement, nor is the Company or any of its
Subsidiaries obligated or committed to make any such loan or advance.

     5.7  Title to Properties; Leases. Except as indicated on Schedule 5.7
attached hereto, the Company and its Subsidiaries own all of the assets
reflected in the consolidated balance sheet of the Company and its Subsidiaries
as at the Balance Sheet Date or acquired since that date (except property and

that date), subject to no rights of others, including any mortgages, leases,
conditional sales agreements, title retention agreements, Liens or other
encumbrances, except for (a) Permitted Liens and (b) Liens that encumber or
otherwise restrict assets with an aggregate fair market value less than

its Subsidiaries is set forth on Schedule 5.7 hereto.

                                       35



     5.9  Financial Statements and Projections.

          5.9.1  Fiscal Year. The Company and each of its Subsidiaries have a
fiscal year that is the 12 months ending on December 31 of each calendar year.

          5.9.2  Financial Statements. Except as set forth on Schedule 5.9
hereto, the Financial Statements have been prepared in accordance with generally
accepted accounting principles and fairly present in all material respects the
consolidated financial condition of the Company and its Subsidiaries as at the
close of business on the date thereof and the results of operations for the
periods then ended (subject, in the case of unaudited statements, to year-end
and audit adjustments and the absence of footnotes). There are no contingent
liabilities of the Company or any of its Subsidiaries as of such dates involving
material amounts, known to the Company, which were not disclosed in such balance
sheets and the notes related thereto.

          5.9.3  Projections. The projections of the annual operating budgets of
the Company and its Subsidiaries on a consolidated basis, balance sheets and
cash flow statements for the 2002 to 2006 fiscal years and the Pro Forma
Financial Projections, copies of which have been delivered to each Purchaser,
disclose all material assumptions made with respect to general economic,
financial and market conditions used in formulating such projections. To the
Knowledge of the Company no facts exist that (individually or in the aggregate)
would result in any materially adverse change in any of such projections. The
projections are based upon reasonable estimates and assumptions, have been
prepared on the basis of the assumptions stated therein and reflect the
reasonable estimates of the Company of the results of operations and other
information projected therein. It is recognized by the Purchasers that such
projections as to future events are not to be viewed as facts, assurances or
guarantees, that underlying assumptions may not materialize or may prove to be
incorrect, that unanticipated events and circumstances may occur, and that
actual results during the period or periods covered by any such projections
likely will vary from the projected results. The assumptions underlying the
projections are inherently uncertain and are subject to significant business,
economic and competitive uncertainties.

          5.9.4  Pro Forma Balance Sheet. The Pro Forma Balance Sheet delivered
to the Purchasers sets forth the assets and liabilities of the Company and its
Subsidiaries on a pro forma basis after taking into account the consummation
(through the Closing Date) of the transactions contemplated in this Agreement as
of August 31, 2002. The Pro Forma Balance Sheet has been prepared by the Company
in accordance with generally accepted accounting principles, consistently
applied, and fairly presents in all material respects the assets and liabilities
of the Company and its Subsidiaries, reflecting the consummation of all of the
transactions contemplated in this Agreement and the other Senior Notes Documents
and based on the assumptions set forth therein as of the Closing Date.

     5.10 Tax Status. The Company and its Subsidiaries (a) have made or filed
all material federal, foreign, state, provincial and local income and all other
tax returns, reports and declarations required by any jurisdiction to which any
of them is subject, (b) have paid all taxes

                                       36



and other governmental assessments and charges shown or determined to be due on
such returns, reports and declarations, except those being contested in good
faith and by appropriate proceedings and (c) have set aside on their books
provisions reasonably adequate for the payment of all taxes for periods
subsequent to the periods to which such returns, reports or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction, and, to the Knowledge of the Company, no basis
for any such claim.

     5.11 Permits; Compliance with Laws. The Company has all franchises,
authorizations, approvals, orders, consents, licenses, certificates, permits,
registrations, qualifications or other rights and privileges (collectively
"Permits") reasonably necessary to permit it to own its property and to conduct
its business as it is presently conducted or proposed to be conducted, and all
such Permits are valid and in full force and effect. No Permit is subject to
termination as a result of the execution of this Agreement, consummation of the
transactions contemplated hereby or by any other Senior Notes Document. The
Company is now and has heretofore been in compliance with all applicable
statutes, ordinances, orders, rules and regulations promulgated by any U.S.
federal, state, municipal, non-U.S. or other governmental authority that apply
to the conduct of its business, except where the failure to so comply could not
reasonably be expected to have a Material Adverse Effect. The Company has never
entered into or been subject to any judgment, consent decree, compliance order
or administrative order with respect to any aspect of the business, affairs,
properties or assets of the Company or received any request for information,
notice, demand letter, administrative inquiry or formal or informal complaint or
claim from any regulatory agency with respect to any aspect of the business,
affairs, properties or assets of the Company that could reasonably be expected
to have a Material Adverse Effect.

     5.12 Compliance with Organizational Documents. None of the Company or any
of its Subsidiaries is in violation of any provision of its Organizational
Documents.

     5.13 Government Regulation. Neither the Company nor any of its Subsidiaries
is a "holding company", or a "subsidiary company" of a "holding company", or an
"affiliate" of a "holding company", as such terms are defined in the Public
Utility Holding Company Act of 1935; nor is it an "investment company", or an
"affiliated company" or a "principal underwriter" of an "investment company", as
such terms are defined in the Investment Company Act of 1940; nor is it subject
to regulation under the Federal Power Act, the Interstate Commerce Act or any
other requirement and law which purports to regulate or restrict its ability to
borrow money.

     5.14 Absence of Financing Statements, etc. Except with respect to Permitted
Liens, there is no financing statement, security agreement, chattel mortgage,
real estate mortgage or other document filed or recorded with any filing
records, registry or other public office, that purports to cover, affect or give
notice of any present or possible future lien on, or security interest in, any
assets or property of the Company or any of its Subsidiaries or any rights
relating thereto.

                                       37



     5.15 Potential Conflicts of Interest. Except as set forth on Schedule 5.15,
to the Knowledge of the Company and its Subsidiaries, no officer, director,
stockholder or Affiliate of the Company or any of its Subsidiaries, (a) owns,
directly or indirectly, any interest in (excepting less than 1.0% equity holding
for investment purposes in securities of publicly held and traded companies), or
is an officer, director, employee or consultant of, any Person that is, or is
engaged in business as, a competitor (e.g., a business engaged in the industrial
minerals or marine transportation businesses), lessor, lessee, supplier,
distributor, sales agent or customer of, or creditor to or borrower from the
Company or any of its Subsidiaries; (b) owns, directly or indirectly in whole or
in part, any tangible or intangible property that the Company or any of its
Subsidiaries uses in the conduct of business; or (c) has any cause of action or
other claim whatsoever against, or owes or has advanced any amount to the
Company or any of its Subsidiaries except for claims in the ordinary course of
business such as for accrued vacation pay, accrued benefits under employee
benefit plans, and similar matters and agreements existing on the date hereof.

     5.16 Certain Transactions. Except for arm's length transactions pursuant to
which the Company or any of its Subsidiaries makes payments in the ordinary
course of business upon terms no less favorable than the Company or such
Subsidiary could obtain from third parties and described on Schedule 5.16, none
of the officers, directors, or employees of the Company or any of its
Subsidiaries (or any of their respective family members) or, to the Knowledge of
the Company, stockholders of the Company (or any of their respective family
members) is presently a party to any transaction with the Company or any of its
Subsidiaries, including any contract, agreement or other arrangement providing
for the furnishing of services to or by, providing for rental of real or
personal property to or from, or otherwise requiring payments to or from any
such Person or, to the Knowledge of the Company, any corporation, partnership,
limited liability company, trust or other entity in which any officer, director,
or any such employee or family member has a substantial interest or is an
officer, director, partner, member or trustee.

     5.17 Employee Benefit Plans.

          5.17.1 In General. Each Employee Benefit Plan and each Guaranteed
Pension Plan has been maintained and operated in compliance in all material
respects with the provisions of ERISA and, to the extent applicable, the Code,
including but not limited to the provisions thereunder respecting prohibited
transactions and the bonding of fiduciaries and other Persons handling plan
funds as required by Section 412 of ERISA. The Company has heretofore delivered
to the Purchasers the most recently completed annual report, Form 5500, with all
required attachments, and actuarial statement required to be submitted under
Section 103(d) of ERISA, with respect to each Guaranteed Pension Plan.

          5.17.2 Terminability of Welfare Plans. Except as disclosed on Schedule
5.17.2, (a) other than normal severance plans, no Employee Benefit Plan that is
an employee welfare benefit plan within the meaning of Section 3(1) or Section
3(2)(B) of ERISA, provides benefit coverage subsequent to termination of
employment, except as required by Title I, Part 6 of ERISA or the applicable
state insurance laws and (b), the Company may terminate each such

                                       38



Employee Benefit Plan at any time (or at any time subsequent to the expiration
of any applicable bargaining agreement) in the discretion of the Company without
liability to any Person other than for claims arising prior to termination.

          5.17.3 Guaranteed Pension Plans. Each contribution required to be made
to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien provisions
of Section 302(f) of ERISA, or otherwise, has been timely made. No waiver of an
accumulated funding deficiency or extension of amortization periods has been
received with respect to any Guaranteed Pension Plan, and neither the Company
nor any ERISA Affiliate is obligated to or has posted security in connection
with an amendment to a Guaranteed Pension Plan pursuant to Section 307 of ERISA
or Section 401(a)(29) of the Code. No liability to the PBGC (other than required
insurance premiums, all of which have been paid) has been incurred by the
Company or any ERISA Affiliate with respect to any Guaranteed Pension Plan and
there has not been any ERISA Reportable Event , or any other event or condition
which presents a material risk of termination of any Guaranteed Pension Plan by
the PBGC. Based on the latest valuation of each Guaranteed Pension Plan (which
in each case occurred within twelve months of the date of this representation),
the aggregate benefit liabilities of all such Guaranteed Pension Plans within
the meaning of Section 4001 of ERISA did not exceed the aggregate value of the
assets of all such Guaranteed Pension Plans, disregarding for this purpose the
benefit liabilities and assets of any Guaranteed Pension Plan with assets in
excess of benefit liabilities, by more than $250,000.

          5.17.4 Multiemployer Plans. None of the Company or any ERISA Affiliate
has incurred any material liability (including secondary liability) to any
Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under Section 4201 of ERISA or as a result of a sale of
assets described in Section 4204 of ERISA. None of the Company or any ERISA
Affiliate has been notified that any Multiemployer Plan is in reorganization or
insolvent under and within the meaning of Section 4241 or Section 4245 of ERISA
or is at risk of entering reorganization or becoming insolvent, or that any
Multiemployer Plan intends to terminate or has been terminated under Section
4041A of ERISA.

          5.17.5 Stock-Based Plans. Each of the Stock-Based Plans is identified
on Schedule 3.8. Each of the Stock-Based Plans has been duly authorized by all
necessary corporate and stockholder action. Sufficient shares of Capital Stock
have been duly reserved for issuance under the Stock-Based Plans.

     5.18 Environmental Compliance.

                 (a)  None of the Company and its Subsidiaries, or any of their
     facilities, improvements, activities or operations is in violation, or
     alleged violation, of any Environmental Law, except where the failure to so
     comply could not reasonably be expected to have a Material Adverse Effect.

                 (b)  Except as specifically identified on Schedule 5.18(b),
     neither the Company nor any of its Subsidiaries has received notice from
     any third party including,

                                       39

     other third party has conducted or has ordered a site assessment, remedial
     investigation, monitoring, removal or other remedial action pursuant to any
     Environmental Law; or (iii) that it is or shall be a named party to any
     claim, action, cause of action, complaint, or legal or administrative
     proceeding (in each case, contingent or otherwise) arising out of any third
     party's incurrence of costs, expenses, losses or damages of any kind
     whatsoever in connection with the Release of Hazardous Substances.

               (c)  Except as specifically identified on Schedule 5.18(c)
     attached hereto: (i) no portion of the Real Estate has been used by the
     Company or any of its Subsidiaries, or to the Knowledge of the Company, by
     any other Person for the handling, processing, generation, manufacture,

     underground tank, surface impoundment, lagoon or underground storage
     receptacle for Hazardous Substances is located on any portion of the Real
     Estate; (iii) in the course of any activities conducted by the Company or

     comply would have a Material Adverse Effect; (iv) there have been no
     Releases or threatened Releases of Hazardous Substances by the Company or

     into or from the properties of the Company or its Subsidiaries by any
     Person; and (v) to the Knowledge of the Company, there have been no
     Releases on, upon, at, to, from or into any real property in the vicinity
     of any of the Real Estate which, through soil or groundwater contamination,
     may have come to be located on any of the Real Estate, except where such
     Release is in an amount or concentration that does not require reporting to
     any governmental authority or any response action under applicable
     Environmental Law; and (vi) none of the Company, its Subsidiaries or any of
     their operations or the Real Estate is subject to any applicable
     Environmental Law requiring the performance of Hazardous Substances site
     assessments by the Company or such Subsidiary, or the removal or
     remediation of Hazardous Substances by the Company or such Subsidiary, or
     the giving of notice by the Company or such Subsidiary to any governmental
     agency or the recording or delivery to other Persons of an environmental
     disclosure document or statement by virtue of the transactions set forth
     herein and

                                       40

     Governmental Authority at the federal, state, or local level in connection
     with the presence on or off such property of any Hazardous Substance.

               (e)  Except as specifically identified on Schedule 5.18(e),
     neither the Company nor any Subsidiary: (i) has entered into or been
     subject to any consent decree, compliance order, or administrative order
     with respect to any Real Estate or any facilities or improvements or any
     operations or activities thereon; nor (ii) has received any request for
     information, demand letter, or administrative inquiry with respect to
     environmental matters, and the Company and its Subsidiaries have no reason
     to believe that any of the above will be forthcoming, in each case, in the
     past three years or with respect to any matter that is currently pending,
     in effect or remains unresolved.

               (f)  Schedule 5.18(f) lists all of the reports summarizing the
     findings of an environmental evaluation of sites, locations or facilities
     owned, occupied or operated by the Company or any of its Subsidiaries other
     than privileged internal environmental reports of, prepared, in each case,
     by personnel of, the Company and its Subsidiaries in the past three years
     or with respect to any matter that is currently pending, in effect or

     has made available to the Purchasers true and correct copies of all
     Environmental Reports and all documents or information in the possession or
     control or available to the Company or its Subsidiaries concerning
     environmental matters relevant to sites, locations or facilities owned,
     occupied or operated by the Company and its Subsidiaries.

     5.19 Insurance. The Company and each of its Subsidiaries maintains with
financially sound and reputable insurers having an A- rating or better from

shall have occurred and be continuing, the Company may

                                       50



terminate the existence of Global Stone Oakville, Inc., a Canadian corporation,
if such termination is, in the good faith judgment of the Board of Directors of
Global Stone Oakville, Inc., desirable in the conduct of its business and such
dissolution could not reasonably be expected to have a Material Adverse Effect.
The Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its material rights and franchises and those of
its Subsidiaries. The Company (i) will cause all of its properties and those of
its Subsidiaries used or useful in the conduct of its business or the business
of its Subsidiaries to be maintained and kept in good condition, repair and
working order, ordinary wear and tear excepted, (ii) will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times, and
(iii) will, and will cause each of its Subsidiaries to, continue to engage
primarily in the businesses now conducted by them and in related businesses;
provided that nothing in this Section 6.6 shall prevent the Company from
discontinuing the operation and maintenance of any of its properties or any of
those of its Subsidiaries if such discontinuance is, in the judgment of the
Company, desirable in the conduct of its or their business and that could not
reasonably be expected to have a Material Adverse Effect.

     6.7  Insurance.

               (a)  The Company will, and will cause each of its Subsidiaries
     to, maintain with financially sound and reputable insurers having an
     A-rating or better from Best's Rating Service insurance with respect to its
     properties and business against such casualties and contingencies as shall
     be in accordance with the general practices of businesses engaged in
     similar activities in similar geographic areas and in amounts, containing
     such terms, in such forms and for such periods as may be reasonable and
     prudent and customary for similar businesses; provided that the Company and
     its Subsidiaries may, in lieu of such insurance, self-insure by maintaining
     full reserves with respect to any such casualties and contingencies, which,
     in the aggregate are not likely to exceed $3,000,000 at any time, so long
     as (i) such reserves are reflected in the consolidated balance sheet of the
     Company and its Subsidiaries in accordance with GAAP, and (ii) with respect
     to any self-insurance that when fully reserved as required hereby, is or is
     likely to exceed $1,000,000, (A) are maintained in an amount at least equal
     to, and otherwise as recommended by an actuary or similar third-party
     professional of national standing and (B) the failure to maintain insurance
     as otherwise required under this Section 6.7(a) shall have been approved in
     writing by holders of at least 50% of the outstanding principal of the
     Senior Notes, which approval shall not be unreasonably withheld. The
     Company will, and will cause each of its Subsidiaries to, maintain
     insurance on the Real Estate in accordance with the terms of any lease or
     mortgage applicable to the Real Estate.

               (b)  The Company will, and will cause each of its Subsidiaries
     to, enforce all of the Company's and its Subsidiaries' rights under all
     insurance policies covering its and their current and former properties and
     business, and pursue all material

                                       51



     remedies available to the Company and its Subsidiaries with diligence and
     in good faith in connection with the enforcement of any such rights.

     6.8  Taxes. The Company will, and will cause each of its Subsidiaries to,
duly pay and discharge, or cause to be paid and discharged, before the same
shall become overdue, all taxes, assessments and other governmental charges
imposed upon it and its real properties, sales and activities, or any part
thereof, or upon the income or profits therefrom, as well as all claims for
labor, materials, or supplies that if unpaid could reasonably be expected to by
law become a lien or charge upon any of its property; provided that any such
tax, assessment, charge, levy or claim need not be paid if the validity or
amount thereof shall currently be contested in good faith by appropriate
proceedings and if the Company or such Subsidiary shall have set aside on its
books adequate reserves with respect thereto; and provided further that the
Company and each of its Subsidiaries will pay all such taxes, assessments,
charges, levies or claims forthwith upon the commencement of proceedings to
foreclose any lien that may have attached as security therefor.

     6.9  Inspection of Properties and Books, etc.

          6.9.1 General. The Company shall permit the Noteholders and their
respective designated representatives, upon reasonable notice if no Default has
occurred and is continuing (and at any time without notice if a Default has
occurred and is continuing) to visit and inspect any of the properties of the
Company or any of its Subsidiaries, to examine the corporate, financial and
operating records of the Company and its Subsidiaries (and to make copies
thereof and extracts therefrom), and to discuss the affairs, finances and
accounts of the Company and its Subsidiaries with, and to be advised as to the
same by, its and their officers, all at such reasonable times and intervals,
during normal business hours if no Default has occurred and is continuing as any
Noteholder may reasonably request (and at any time and without notice if a
Default has occurred and is continuing). So long as no Default has occurred and
is continuing, each Noteholder agrees to use commercially reasonable efforts to
coordinate any visit or inspection thereby (or by its representatives) pursuant
to this Section with the chief financial officer of the Company.

          6.9.2 Communications with Accountants. The Company authorizes each
Noteholder, if a Default shall have occurred and be continuing, to communicate
directly with the independent certified public accountants of the Company;
provided that each Noteholder shall give the Company prior notice of such
communications. The Company further authorizes such accountants to disclose to
the Noteholders any and all financial statements and other supporting financial
documents and schedules, including copies of any management letter, with respect
to the business, financial condition and other affairs of the Company or any of
its Subsidiaries, at the expense of the Company. At the request of Noteholders
holding at least 50% of the principal amount of the Senior Notes then
outstanding, the Company shall deliver (promptly upon such request) a letter
addressed to such accountants instructing them to comply with the provisions of
this Section 6.9.2.

                                       52

will, and will cause each of its Subsidiaries to, comply with (i) the applicable
laws and regulations wherever its business is conducted, including all
Environmental Laws, except where the failure to so comply is not otherwise
expressly prohibited hereunder and such failure is not likely to have a Material
Adverse Effect, (ii) the provisions of its charter documents and by-laws, (iii)
all material agreements and instruments by which it or any of its properties may
be bound and (iv) all applicable decrees, orders, and judgments. If any Permit
from any Governmental Authority shall become necessary or required in order that
the Company or any of its Subsidiaries may fulfill any of its obligations
hereunder or under any of the other Senior Notes Document to which the Company
or such Subsidiary is a party, the Company will, or (as the case may be) will
cause such Subsidiary to, immediately take or cause to be taken all reasonable
steps within the power of the Company or such Subsidiary to obtain such Permit
and furnish the Noteholders with evidence thereof.

     6.11 Employee Benefit Plans. The Company will (a) promptly upon filing the
same with the Department of Labor or Internal Revenue Service upon request of a
Noteholder, furnish to the Noteholders a copy of the most recent actuarial
statement required to be submitted under Section 103(d) of ERISA and Annual
Report, Form 5500, with all required attachments, in respect of each Guaranteed
Pension Plan and (b) promptly upon receipt or dispatch, furnish to the
Noteholders any notice, report or demand sent or received in respect of a
Guaranteed Pension Plan under Sections 302, 4041, 4042, 4043, 4063, 4065, 4066
and 4068 of ERISA, or in respect of a Multiemployer Plan, under Sections 4041A,
4202, 4219, 4242, or 4245 of ERISA.

     6.12 Subsidiaries, Etc. The Company will not create or have (or permit any
Subsidiary to create or have) any Subsidiaries other than (a) Subsidiaries in
existence on the date hereof, (b) Subsidiaries acquired in accordance with
Section 7.5.1, and (c) direct Subsidiaries of any Guarantor (other than a
Restricted Guarantor) created in connection with any transaction permitted under
the terms of this Agreement; provided that in each case under clauses (b) and
(c), such Subsidiary is wholly-owned, directly or indirectly, by the Company and
is not a Subsidiary of any of the Restricted Guarantors and, before and after
giving effect to the formation or acquisition of such Subsidiary, no Default
shall have occurred and be continuing. If, after the Closing Date, the Company
or any of its Subsidiaries creates or acquires, either directly or indirectly,
any Subsidiary, the Company or such Subsidiary (or its parent if such Subsidiary
is not then a Guarantor) will immediately (and in any event not later than five
Business Days following such creation or acquisition, as the case may be) (i)
notify the Noteholders thereof, (ii) cause each Material Subsidiary created,
acquired or otherwise then existing to become an unlimited, joint and several,
guarantor of all of the Guaranteed Obligations, and (iii) cause such Material
Subsidiary(ies) to execute and deliver to the Noteholders: (A) a joinder to this
Agreement in the form of Exhibit A hereto; (B) documentation of the type
described in Sections 3.2(a), (b), (c), (g).and (j); (C) legal opinions in form
and substance satisfactory to the Noteholders opining as to the authorization,

Noteholders, and such other matters and the

                                       53



Noteholders may request; and (D) and such other documentation as the Noteholders
may reasonably request.

     6.13 Intellectual Property. The Company covenants and agrees that it will
take all reasonably necessary and advisable steps to obtain ownership in and/or
protection of all material Intellectual Property owned, used or developed by the
Company and its Subsidiaries in the conduct of their business, and that it will
not do any act, or omit to do any act, nor permit any licensee to do any act,
whereby any material Intellectual Property rights of the Company or any
Subsidiary may become abandoned, invalidated, dedicated to the public domain, or
diminished in value; provided, however, that nothing in this Section 6.13 shall
prevent the Company from taking, or refraining from taking, any action if such
action (or refraining from taking action) is in the judgment of the Company in
its best interest and that would not, individually or in the aggregate, have a
Material Adverse Effect. Without limiting the generality of the foregoing, the
Company covenants and agrees that it will diligently prosecute any applications
to obtain registrations of material Intellectual Property, other than
Intellectual Property of a type that is not capable of cost effective protection
or is not eligible for protection through registration; preserve and maintain
all material Intellectual Property rights in all jurisdictions in which the
Company conducts or proposes to conduct business; display appropriate notices of
material Intellectual Property rights on all tangible embodiments; take
reasonable security measures to protect the secrecy and confidentiality of all
valuable information of the Company and its licensors; file all such
applications, renewals, certificates and affidavits as may be reasonably
necessary or advisable to obtain and maintain the ownership, validity and
enforceability of all material Intellectual Property rights of the Company and
its Subsidiaries; appropriately document the Company's ownership of material
Intellectual Property developed by or for the Company and its Subsidiaries; take
all reasonable enforcement actions as may be prudent to protect the material
Intellectual Property of the Company and its Subsidiaries; and conduct the
business of the Company and its Subsidiaries so as not to violate or infringe
the Intellectual Property rights of others.

     Noteholder that purchased its entire investment in the Senior Notes or to
     one of the initial Noteholders that owns in excess of $10,000,000 in
     principal amount of the Senior Notes. The Company will have no obligation
     to recognize the newly designated Representative at the next meeting of the
     Board of Directors if it does not receive at least fifteen days prior to
     the next scheduled meeting of the Board of Directors written notice of the
     designation of the new Representative and an executed copy of the

     Collateral Agent, in its sole discretion, issued by the Title Company for
     each of the properties subject to the Realty Mortgages (collectively, the
     "Loan Policies" and individually, a "Loan Policy"), with a face value of
     not less than $75,000,000 insuring each mortgage or deed of trust, as

     any mortgage, deed of trust, deed to secure debt, or other security
     instrument, as appropriate ("Real Estate Security Instrument"), granted by
     the Company, or any Guarantor as the case may be, to the Collateral Agent,

     or security interest in all real property owned or leased by the Company or
     Guarantor at the locations listed on Schedule 5.7 of this Agreement and to

     portion of its Property to the Collateral Agent shall apply only to such
     Property or interests on which liens (including fixture filings and
     leasehold mortgages) are to be granted to secure the Syndicated Debt.

                 (d)  The Company agrees to promptly inform the Collateral Agent
     if it acquires any additional Real Estate and, if so requested by the
     Collateral Agent, the Company agrees to: (a) grant the Collateral Agent a

     case, only to the extent that the Company has or intends to furnish a
     corresponding Lien and title insurance to the Agent and the Banks under the
     Syndicated Facility Documents.

          6.16.2 Vessels. The Company agrees to provide the Collateral Agent
with thirty (30) days prior written notice if any of the Liens granted pursuant
to the Vessel Financing Documents are to be discharged and, if so requested by

notice to the Company, declare the entire unpaid principal amount of the Senior
Notes, plus the applicable Prepayment Premium under Section 2.5.2 if such
declaration shall occur on or after October 25, 2004 and otherwise in a
principal amount equal to 118% of the principal amount of the Senior Notes,
plus, in any case, all interest accrued and unpaid thereon and all other amounts
payable under this Agreement to be forthwith due and payable, whereupon the
Senior Notes, such premium, all such accrued interest and all such amounts shall
become and be forthwith due and payable (unless there shall have

                                       72



occurred an Event of Default under Sections 9.1(i) or (j), in which case all
such amounts shall automatically become due and payable), without presentment,
demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Company, and (2) in the case of Events of Default under clauses
(a) or (b) above, each Noteholder may proceed to protect and enforce its rights
by suit in equity, action at law and/or other appropriate proceeding either for
specific performance of any covenant, provision or condition contained or
incorporated by reference in this Agreement or in aid of the exercise of any
power granted in this Agreement. Notwithstanding the foregoing, but only so long
as the Noteholders shall not have exercised their rights under clauses (1) and
(2) above, with respect to any Event of Default under clause (g) above, such
Event of Default shall be, and shall be deemed to be, for all purposes
hereunder, cured if the "Event of Default" (as defined in the Syndicated
Facility Documents and the Vessel Financing Documents) giving rise to such Event
of Default shall have been cured or waived in accordance with the terms of the
Syndicated Facility Documents and the Vessel Financing Documents and the
Noteholders shall have received written notice thereof (which notice shall
summarize the pertinent facts of such cure and include a true and correct copy
of such waiver); provided that no such cure shall affect (whether to cure,
postpone or otherwise) whether an Event of Default has existed, currently exists
or will exist under or with respect to any other clause of this Section 9.1
notwithstanding that any other such Event of Default arises or may arise under
or on account of the same acts, omissions or circumstances that give rise (or
gave rise) to an Event of Default under clause (g).

     9.2  Remedies. In case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Noteholders shall have
accelerated the maturity of the Senior Notes pursuant to Section 9.1, each
Noteholder, if owed any amount with respect to the Senior Notes, may proceed to
protect and enforce its rights by suit in equity, action at law or other
appropriate proceeding, subject to the limitations on acceleration in Section
9.1 above, whether for the specific performance of any covenant or agreement
contained in this Agreement and the other Senior Notes Documents or any
instrument pursuant to which the Senior Notes Obligations to such Noteholder are
evidenced, including as permitted by applicable law the obtaining of the ex
parte appointment of a receiver (but only to the extent that Noteholders holding
greater than 50%, voting together as a single class, in principal amount of the
Senior Notes have consented to such appointment), and, if such amount shall have
become due by declaration or otherwise, proceed to enforce the payment thereof
or any other legal or equitable right of such Noteholder. No remedy herein
conferred upon any Noteholder is intended to be exclusive of any other remedy
and each and every remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or any other provision of law.

     9.3  Distribution of Proceeds. In the event that following the occurrence
or during the continuance of any Default or Event of Default, any Noteholder
receives any monies with respect to the amounts due hereunder, such monies shall
be distributed for application as follows:

               (a)  First, to the payment of, or (as the case may be) the
     reimbursement of the Noteholders for or in respect of all reasonable costs,
     expenses, disbursements and

                                       73



     losses which shall have been incurred or sustained by the Noteholders in
     connection with the collection of such monies by the Noteholders, for the
     exercise, protection or enforcement by the Noteholders of all or any of the
     rights, remedies, powers and privileges of the Noteholders under this
     Agreement or any of the other Senior Notes Documents pro rata based on the
     relative amount so incurred or sustained;

               (b)  Second, to all other Senior Notes Obligations in such order
     or preference as the Noteholders may determine; provided, however, that
     distributions shall be made among the Noteholders pro rata; and

               (c)  Third, the excess, if any, shall be returned to the Company
     or to such other Persons as are entitled thereto.

     9.4  Annulment of Defaults. Section 9.1 is subject to the condition that,
if at any time after the principal of any of the Senior Notes shall have become
due and payable, and before any judgment or decree for the payment of the moneys
so due, or any portion thereof, shall have been entered, then and in every such
case the holders of greater than 51%, voting together as a single class, in
principal amount of all Senior Notes then outstanding may, by written instrument
filed with the Company, rescind and annul such declaration and its consequences;
but no such rescission or annulment shall extend to or affect any subsequent
default or Event of Default or impair any right consequent thereon.

                   ARTICLE X - GUARANTEE OF THE SENIOR NOTES

     Each Guarantor unconditionally guarantees, as a primary obligor and not
merely as a surety, jointly and severally with each other Guarantor, the due and
punctual payment of the principal of, and interest on, each of the Senior Notes
when and as due, whether at maturity, by acceleration, by notice of prepayment
or otherwise and the due and punctual payment and performance of all other
Senior Notes Obligations with respect to the Senior Notes (the "Guaranteed
Obligations"). Each Guarantor further agrees that the Guaranteed Obligations may
be extended and renewed, in whole or in part, without notice to or further
assent from it, and that it will remain bound upon its guarantee notwithstanding
any extension or renewal of any Guaranteed Obligations.

     Each Guarantor waives presentment to, demand of payment from and protest to
the Company of any of the Guaranteed Obligations, and also waives notice of
acceptance of its guarantee and notice of protest for nonpayment. The
obligations of a Guarantor hereunder shall not be affected by (a) the failure of
any Noteholder to assert any claim or demand or to enforce any right or remedy
against the Company, as the case may be, or any other Guarantor under the
provisions of this Agreement, the Senior Notes or any of the other Senior Notes
Documents or otherwise; (b) any rescission, waiver, amendment or modification of
any of the terms or provisions of this Agreement, the Senior Notes any guarantee
or any other agreement, (c) the failure of any Noteholder to exercise any right
or remedy against any other Guarantor of any obligations hereunder; or (d) the
failure of any Noteholder to take, register, perfect or preserve any security
for any of the obligations hereunder.

                                       74



     The obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including,
without limitation, any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense or set off, counterclaim,
recoupment or termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Guaranteed Obligations or otherwise. Without limiting
the generality of the foregoing, the obligations of each Guarantor hereunder
shall not be discharged or impaired or otherwise affected by the failure of any
Noteholder to assert any claim or demand or to enforce any remedy under this
Agreement, the Senior Notes, or under any other guarantee or agreement, by any
waiver or modification of any provision thereof, by any default, failure or
delay, willful or otherwise, in the performance of any Guaranteed Obligations,
or by any other act or omission which may or might otherwise in any manner or to
any extent vary the risk or reduce or extinguish the liability of such Guarantor
or otherwise operate as a discharge of such Guarantor as a matter of law or
equity.

     Each Guarantor further agrees that its guarantee shall be a continuing
guarantee and shall stand as a guarantee of full and final payment and
performance of all Guaranteed Obligations hereunder from time to time and shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal or interest on any obligation
hereunder is rescinded or must otherwise be returned by the Noteholders upon the
bankruptcy or reorganization of the Company or otherwise.

     Each Guarantor hereby waives and releases in favor of the Noteholders all
rights of subrogation against or in respect of the Company and its property and
all rights of indemnification, contribution and reimbursement from the Company
and its property, in each case in connection with this guarantee and any
payments made hereunder, and regardless of whether such rights arise by
operation of law, pursuant to contract or otherwise until such time as the
obligations hereunder have been fully and finally performed and paid.

     If, in any action to enforce this guaranty or any proceeding to allow or
adjudicate a claim under this guaranty, a court of competent jurisdiction
determined that enforcement of this guaranty against any Guarantor for the full
amount of the obligations hereunder is not lawful under, or would be subject to
avoidance under, Section 548 of the United States Bankruptcy Code or any
applicable provision of comparable state law, the liability of such Guarantor
under this guaranty shall be limited to the maximum amount lawful and not
subject to avoidance under such law.

     The Company and its Subsidiaries agree that in the event a payment shall be
made by the Company or its Subsidiaries (the "Claiming Note Party") under this
Agreement or any other Senior Notes Documents or assets of such Claiming Note
Party shall be sold pursuant to any mortgage, security agreement or similar
instrument or agreement to satisfy a claim of any of the Noteholders, each other
party to this Agreement (a "Contributing Note Party") shall indemnify the
Claiming Note Party in an amount equal to the amount of such payment or the
greater of the book value or the fair market value of such assets, as the case
may be multiplied by a fraction of which the numerator shall be the net worth of
the Contributing Note Party on the date hereof

                                       75



and the denominator shall be the aggregate net worth of all the parties to this
Agreement on the date hereof.

                           ARTICLE XI - MISCELLANEOUS

     11.1 No Waiver; Cumulative Remedies. No failure or delay on the part of any
Noteholder, in exercising any right, power or remedy hereunder shall operate as
a waiver thereof; nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy hereunder. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

     11.2 Amendments, Waivers and Consents. Any provision in this Agreement, the
Senior Notes or the other Senior Notes Documents to the contrary
notwithstanding, this Agreement may be amended, supplemented or otherwise
modified and compliance with any covenant or provision set forth herein may be
omitted or waived, if the Company shall, as long as any Senior Notes are
outstanding, obtain consent thereto in writing from the holder or holders of at
least 50%, voting together as a single class, in principal amount of all Senior
Notes then outstanding, and shall, in any case, deliver copies of such
amendment, supplement, modification or consent, as the case may be, in writing
to all other holders of Senior Notes; provided that no such consent shall be
effective (a) to reduce or to postpone the date fixed for the payment of or the
amount of, or rate of, the principal (including any required redemption or
repurchase of any Senior Note) or interest payable on any Senior Note, (b) or to
modify in any way the ranking of the Senior Notes Obligations evidenced by such
Senior Note, (c) to alter or amend any provisions relating to prepayments,
mandatory purchase or redemption of such Senior Notes, (d) or to alter or amend
the consent mechanism provided for under Section 9.4 or this Section 11.2, in
the case of clauses (a) through (c) of such Senior Note and, in the case of
clause (d), all holders of Senior Notes outstanding. Any waiver or consent may
be given subject to satisfaction of conditions stated therein and any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. Written notice of any waiver or consent effected under
this Section shall promptly be delivered by the Company to any Noteholders who
did not execute the same.

     11.4 Costs, Expenses and Taxes. The Company agrees to pay on demand all
reasonable costs and expenses of the Noteholders in connection with the
preparation, execution and delivery of this Agreement, the Senior Notes, the
other Senior Notes Documents and other instruments and documents to be delivered

contemplated hereby and thereby, as well as all reasonable costs and expenses

                                       77



of the Noteholders in connection with the amendment, waiver (whether or not such
amendment or waiver becomes effective) or enforcement of this Agreement, the
Senior Notes, the other Senior Notes Documents, and other instruments and
documents to be delivered hereunder and thereunder, including without limitation
the expenses of the Noteholders under Section 6.9.1 hereof at any time after a

and in addition to the provisions of such sentence, the Company agrees to pay on
demand all reasonable fees and out of pocket expenses of Goodwin Procter LLP,
special counsel to the Purchasers in connection with the transactions
contemplated by this Agreement, including any amendment, waiver (whether or not
such amendment or waiver becomes effective) or enforcement of this Agreement,

any and all stamp and other similar taxes (expressly excluding income and
capital gain taxes) payable or determined to be payable in connection with the

Notes Documents, and the other instruments and documents to be delivered

expenses of delivering copies of Senior Notes Documents to Noteholders, and the
Company agrees to save each Noteholder harmless from and against any and all
liabilities with respect to or resulting from any delay in paying or omission to
pay such taxes and filing fees.

     11.5 Assignability; Binding Agreement. This Agreement may not be assigned
by the Company or any Guarantor without the prior written consent of each other
party hereto. This Agreement shall be binding upon and enforceable by, and shall
inure to the benefit of, the parties hereto and their respective successors and
permitted assigns, and no others. Notwithstanding the foregoing, nothing in this
Agreement is intended to give any Person not named herein the benefit of any
legal or equitable right, remedy or claim under this Agreement.

     11.6 Payments in Respect of Senior Notes. Each Noteholder and any successor
holder of the Senior Notes by their acceptance thereof, agree that, with respect
to all sums received by them applicable to the payment of principal of or
interest on the Senior Notes equitable adjustment will be made among them so
that, in effect, all such sums shall be shared ratably by all of the Noteholders
whether received by voluntary payment, by realization upon security, by the
exercise of the right of set off, by counterclaim or cross-action or by the
enforcement of any or all of the Senior Notes. If any holder of the Senior Notes
receives any payment on its Senior Notes in excess of its pro rata portion, then
such holder receiving such excess payment shall purchase for cash from the other
holders an interest in their Senior Notes in such amounts as shall result in a
ratable participation by all of the holders in the aggregate unpaid amount of
Senior Notes then outstanding. The Company shall not have any obligation to any
Person under this Section 11.6.

     11.7 Indemnification. In addition to the payment of expenses pursuant to
Section 11.4, whether or not the transactions contemplated hereby shall be
consummated, the Company and

                                       78



each Guarantor agrees, jointly and severally, to indemnify, pay and hold each
Noteholder and the partners, members, officers, directors, employees and agents
of each Noteholder (collectively, the "Indemnitees") harmless from and against,
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, expenses and disbursements of any kind or
nature whatsoever (including, without limitation, the reasonable fees and
disbursements of counsel for such Indemnitees in connection with any
investigative, administrative or judicial proceedings, whether or not such
Indemnitees shall be designated a party thereto), which may be imposed on,
incurred by, or asserted against such Indemnitee, in any manner relating to or
arising out of (i) this Agreement, the Senior Notes and the other Senior Notes
Documents and all other matters related thereto or in connection therewith, (ii)
the Noteholders' agreement to purchase the Senior Notes, or the use or intended
use of the proceeds of the Senior Notes hereunder, (iii) the violation of any
securities law by the Company, or any of its Subsidiaries, (iv) the failure of
any of the parties (other than the Purchasers) to the Senior Notes Documents to
comply with any law, rule or regulation applicable to the transactions
contemplated thereby or (v) any Environmental Law, or any Hazardous Substances
(A) present on or under the Real Estate (B) released from or onto the Real
Estate, or (C) generated by the Company or any of its Subsidiaries (the
"Indemnified Liabilities"); provided that the Company shall have no obligation
to an Indemnitee hereunder with respect to Indemnified Liabilities which are
determined by a final court decision or arbitral award to have resulted from the
gross negligence or willful misconduct of that Indemnitee. To the extent that
the undertaking to indemnify, pay and hold harmless set forth in the preceding
sentence may be unenforceable because it violates any law or public policy, the
Company shall contribute the maximum portion which it is permitted to pay and
satisfy under applicable law, to the payment and satisfaction of all Indemnified
Liabilities incurred by the Indemnitees or any of them.

     11.8  Survival of Representations and Warranties. All representations and
warranties made to the Noteholders in this Agreement, the Senior Notes, the
other Senior Notes Documents or any other instrument or document delivered in
connection herewith or therewith, shall survive the execution and delivery
hereof and thereof, acceptance of the Senior Notes, payment of the Senior Notes
or upon redemption, prepayment or otherwise, termination of this Agreement,
regardless of any investigation made by the Noteholders or on behalf of the
Noteholders.

     11.9  Prior Agreements. This Agreement and the other Senior Notes Documents
constitutes the entire agreement between the parties and supersedes any prior
understandings or agreements concerning the subject matter hereof or thereof.

     11.10 Severability. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provision.

     11.11 Governing Law. This Agreement shall be governed by, and construed in
accordance with, the internal laws of the State of New York.

     11.12 Dispute Resolution.

                                       79



          11.12.1 All disputes, claims, or controversies arising out of or
relating to (i) this Agreement or any other agreement executed and delivered
pursuant to this Agreement or the negotiation, breach, termination, validity or
performance hereof or the transactions contemplated hereby or (ii) the
Noteholders' loan to the Company, that are not resolved by mutual agreement
shall be resolved by litigation, or if the Company and each Noteholder agree to
resolve any particular dispute by arbitration, then such arbitration shall be
conducted in accordance with the procedures set forth in Section 11.12.2 below.

          11.12.2 In the event the parties hereto agree to resolve a particular
dispute by arbitration, the following procedures will apply:

               (a)  The dispute will be submitted solely and exclusively by
     binding arbitration to be conducted before J.A.M.S./Endispute, Inc. or its
     successor.

               (b)  The arbitration shall be held in New York, New York before a
     single arbitrator and shall be conducted in accordance with the rules and
     regulations promulgated by J.A.M.S./Endispute, Inc. unless specifically
     modified herein.

               (c)  The parties covenant and agree that the arbitration hearing
     shall commence within 120 days of the date on which a written demand for
     arbitration is filed by any party hereto. In connection with the
     arbitration proceeding, the arbitrator shall have the power to order the
     production of documents by each party and any third-party witnesses. In
     addition, each party may take up to three depositions as of right, and the
     arbitrator may in his or her discretion allow additional depositions upon
     good cause shown by the moving party. However, the arbitrator shall not
     have the power to order the answering of interrogatories or the response to
     requests for admission. In connection with any arbitration, each party
     shall provide to the other, no later than 14 business days before the date
     of the arbitration, the identity of all Persons that may testify at the
     arbitration and a copy of all documents that may be introduced at the
     arbitration or considered or used by a party's witness or expert, and a
     summary of the expert's opinions and the basis for said opinions. The
     arbitrator's decision and award shall be made and delivered within 60 days
     of the conclusion of the arbitration. The arbitrator's decision shall set
     forth a reasoned basis for any award of damages or finding of liability.
     The arbitrator shall not have power to award damages in excess of actual
     compensatory damages and shall not award punitive damages or any other
     damages that are specifically excluded under this Agreement, and each party
     hereby irrevocably waives any claim to such damages.

               (d)  The parties covenant and agree that they will participate in
     the arbitration in good faith and, except as set forth below, shall (i)
     bear their own attorneys' fees costs and expenses in connection with the
     arbitration, and (ii) share equally in the fees and expenses charged by
     J.A.M.S./Endispute, Inc. The arbitrator may in his or her discretion assess
     costs and expenses (including the reasonable legal fees and expenses of the
     prevailing party) against any party to a proceeding. Any party
     unsuccessfully

                                       80



     refusing to comply with an order of the arbitrators shall be liable for
     costs and expenses, including attorneys' fees, incurred by the other party
     in enforcing the award. This Section 11.12 applies equally to requests for
     temporary, preliminary or permanent injunctive relief, except that in the
     case of temporary or preliminary injunctive relief any party may proceed in
     court without prior arbitration for the limited purpose of avoiding
     immediate and irreparable harm. The provisions of this Section 11.12 shall
     be enforceable in any court of competent jurisdiction.

               (e)  Each of the parties hereto irrevocably and unconditionally
     consents to the exclusive jurisdiction of J.A.M.S./Endispute, Inc. to
     resolve all disputes, claims or controversies arising out of or relating to
     this Agreement or the negotiation, breach, termination, validity or
     performance hereof and or the transactions contemplated hereby and further
     consents to the jurisdiction of the courts of the State of New York for the
     purposes of enforcing the arbitration provisions of Section 11.12 of this
     Agreement. Each party further irrevocably waives any objection to
     proceeding before J.A.M.S./Endispute, Inc. based upon lack of personal
     jurisdiction or improper venue and further irrevocably and unconditionally
     waives and agrees not to make a claim in any court that arbitration before
     J.A.M.S./Endispute, Inc. has been brought in an inconvenient forum. Each of
     the parties hereto hereby consents to service of process by registered mail
     at the address to which notices are to be given. Each of the parties hereto
     agrees that its or his submission to jurisdiction and its or his consent to
     service of process by mail are made for the express benefit of the other
     parties hereto.

     11.13 Section Headings and Gender; Construction. The descriptive headings
in this Agreement have been inserted for convenience only and shall not be
deemed to limit or otherwise affect the construction of any provision thereof or
hereof. The use in this Agreement of the masculine pronoun in reference to a
party hereto shall be deemed to include the feminine or neuter, and vice versa,
as the context may require. The parties have participated jointly in the
negotiation and drafting of this Agreement and the other agreements, documents
and instruments executed and delivered in connection herewith with counsel
sophisticated in investment transactions. In the event an ambiguity or question
of intent or interpretation arises, this Agreement and the agreements, documents
and instruments executed and delivered in connection herewith shall be construed
as if drafted jointly by the parties and no presumption or burden of proof shall
arise favoring or disfavoring any party by virtue of the authorship of any
provisions of this Agreement and the agreements, documents and instruments
executed and delivered in connection herewith.

     11.14 Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which when so executed and delivered shall be
taken to be an original; but such counterparts shall together constitute but one
and the same document.

     11.15 Further Assurances. From and after the date of this Agreement, upon
the reasonable request of the Noteholders, the Company and its Subsidiaries
shall execute and deliver such instruments, documents and other writings as may
be reasonably necessary or

                                       81



desirable to confirm and carry out and to effectuate fully the intent and
purposes of the Senior Notes Documents.

     11.16 Consent to Jurisdiction. Except as provided in Section 11.12 above,
the Company and its Subsidiaries irrevocably submit to the non-exclusive
jurisdiction of arbitration in New York, New York to resolve all disputes,
claims or controversies arising out of or relating to (i) this Agreement or any
other agreement executed and delivered pursuant to this Agreement or the
negotiation, validity or performance hereof and thereof or the transactions
contemplated hereby and thereby, or (ii) the Noteholders' loan to the Company,
and further consents to the sole and exclusive jurisdiction of the courts of the
State of New York for the purposes of enforcing the arbitration provisions of
Section 11.12 of this Agreement. Each party further irrevocably waives any
objection to proceeding before the arbitrator in New York, New York based upon
lack of personal jurisdiction or improper venue and further irrevocably and
unconditionally waives and agrees not to make a claim in any court that
arbitration before the arbitrator in New York, New York has been brought in an
inconvenient forum. Each of the parties hereto hereby consents to service of
process by registered mail at the address to which notices are to be given. Each
of the parties hereto agrees that its or his submission to jurisdiction and its
or his consent to service of process by mail are made for the express benefit of
the other parties hereto.

     11.17 Effect of Judgment. The Company agrees, to the fullest extent it may
effectively do so under applicable law, that a judgment in any suit, action or
proceeding of the nature referred to in Section 11.16 brought in any such court
shall, subject to such rights of appeal on issues other than jurisdiction as may
be available to the Company, be conclusive and binding upon the Company and may
be enforced in the courts of the United States of America or the State of New
York (or any other courts to the jurisdiction of which the Company is or may be
subject) by a suit upon such judgment.

     11.18 No Limitation. Nothing in Section 11.16 or 11.17, shall affect the
right of any Noteholder to serve process in any manner permitted by law, or
limit any right that any Noteholder may have to bring proceedings against the
Company in the courts of any jurisdiction or to enforce in any lawful manner a
judgment obtained in one jurisdiction in any other jurisdiction.

     11.19 Specific Performance. Upon breach or default by the Company with
respect to any obligation hereunder or under the Senior Notes, each Noteholder
shall be entitled to protect and enforce its rights at law, or in equity or by
other appropriate proceedings for specific performance of such obligation, or
for an injunction against such breach or default, or in aid of the exercise of
any power or remedy granted hereby or thereby or by law.

     11.20 Actions by Noteholders. Except as provided in Section 11.2, wherever
in this Agreement action is required or permitted to be taken by, or consent is
required of, or a matter requires the satisfaction of, the Noteholders, such
action may be taken by, and/or such consent may be obtained from, and/or such
satisfaction may be expressed by, the holders of greater than

                                       82



50%, voting together as a single class, of the principal amount of all Senior
Notes then outstanding.

     11.21 Non-Disclosure. Each of the Noteholders agrees that it and any of its
representatives shall hold in strict confidence (except as otherwise required by
law) any confidential or proprietary information obtained from the Company and
its Subsidiaries that has been conspicuously marked "confidential". Information
disclosed to or generally known in the industry or obtained or developed by any
Noteholder based on information received from Persons who had a right to
disclose the same to the Noteholders shall not be (and shall not be deemed to
be) confidential or proprietary information. Each Noteholder shall hold all
confidential information obtained by such Noteholder pursuant to the
requirements of this Agreement in accordance with such Noteholder's customary
procedures for handling confidential information of this nature; provided,
however, each Noteholder may disclose such confidential information (a) to its
examiners, affiliates, outside auditors, counsel and other professional
advisors, (b) to any Noteholder, or (c) to any prospective holder of Senior
Notes, provided that such prospective holder shall have executed and delivered,
and otherwise be bound by, a confidentiality agreement in form and substance
substantially similar to Exhibit 6.14, and (d) as required or requested by any
Governmental Authority or representative thereof or pursuant to legal process;
provided, further that (i) unless specifically prohibited by applicable law or
court order, each Noteholder shall use commercially reasonable efforts to give
the Company prompt notice of the applicable request for disclosure of such
non-public information so that the Company may seek an appropriate protective
court order (A) by a governmental authority or representative thereof (other
than any such request in connection with an examination of the financial
condition of such Noteholder by such governmental authority) or (B) pursuant to
legal process, (ii) if, in the absence of a protective order any Noteholder is
compelled to disclose any such non-public information, such Noteholder shall use
commercially reasonable efforts to provide notice to the Company of the
information so disclosed prior to the disclosure thereof, and (iii) in no event
shall any Noteholder be obligated to return any materials furnished by the
Company or any of its Subsidiaries other than those instruments in possession of
any Noteholder evidencing the Senior Notes Obligations once the Senior Notes
Obligations (including the Guaranteed Obligations) have been paid in full in
cash and this Agreement has been terminated in accordance with its terms.

     11.22 Publicity. Except as may be required by applicable law, no party
hereto shall issue a publicity release or announcement or otherwise make any
public disclosure concerning this Agreement or the transactions contemplated
hereby, without prior approval by the other parties hereto. If any announcement
is required by law to be made by a party hereto, prior to making such
announcement such party will deliver a draft of such announcement to the other
parties and shall give the other parties an opportunity to comment thereon.

     11.23 Limitation of Liability. No Noteholder shall have any liability to
the Company or any of its Subsidiaries (whether sounding in tort, contract, or
otherwise) for consequential damages suffered by the Company or any such
Subsidiaries in connection with, arising out of, or in any way related to the
transactions or relationships contemplated by the Senior Notes

                                       83



Documents, or any act, omission or event occurring in connection therewith, or
for any special exemplary or punitive damages, and the Company and its
Subsidiaries hereby waive, to the maximum extent not prohibited by law, any
right they may have to claim or recover any of the foregoing.

     (b)  Perfection.

          (i)  Authorization by Pledgor.

               (A) Perfection by Filing. Pledgor (A) hereby authorizes the
Collateral Agent, at any time and from time to time, to file initial financing
statements, financing statements, continuation statements, and amendments
thereto, including, without limitation, any such financing statements that
describe the Collateral as "all assets" of Pledgor, or words of similar effect,
and (B) otherwise agrees to take such other action and execute such assignments
or other instruments or documents, in each case as the Collateral Agent may
request, to evidence, perfect, or record the Collateral Agent's security
interest in the Collateral or to enable the Collateral Agent to exercise and
enforce its rights and remedies under this Agreement with respect to any
Collateral. Pledgor agrees to furnish any such information to the Collateral
Agent promptly upon request. Any such initial financing statement, financing
statement, continuation statement, or amendment may be filed by the Collateral
Agent on behalf of Pledgor.

               (B) Other Perfection Methods. Pledgor shall, at any time and from
time to time take such steps as the Collateral Agent may reasonably request in
order for the Collateral Agent (1) to obtain an acknowledgment, in form and
substance reasonably satisfactory to the Collateral Agent, of any bailee having
possession of any of the Collateral, stating that the bailee holds such
Collateral for the Collateral Agent as secured party, (2) to obtain "control"
(as such term is defined in the UCC with respect to each of the following types
of Collateral) of any Investment Property, Deposit Accounts, Letter-of-credit
rights, or "electronic chattel paper" (as such term is defined in the UCC), with
any agreements establishing such control to be in form and substance reasonably
satisfactory to the Collateral Agent, and (3) otherwise to insure the continued
perfection and priority of the Collateral Agent's security interest in any of
the Collateral and of the preservation of its rights therein. If Pledgor shall
at any time acquire a "commercial tort claim" (as such term is defined in the
UCC) in excess of $100,000, such Pledgor shall promptly notify the Collateral
Agent thereof in a writing, therein providing a reasonable description and
summary thereof, and upon delivery thereof to the Collateral Agent, such Pledgor
shall be deemed to grant thereby to the Collateral Agent, and such Pledgor
hereby grants to the Collateral Agent, for its benefit and the ratable benefit
of the Noteholders, a security interest and Lien in and to such commercial tort
claim and all proceeds thereof, all upon the terms of, and governed by, this
Agreement.

               (C) Savings Clause. Nothing contained in this Section 3(b) shall
be construed to narrow the scope of the Collateral Agent's security interests or
the perfection or priority thereof or to impair or otherwise limit any of the
rights, powers, privileges, or remedies of the Agent under any of the Senior
Notes Documents.

                                       6



          (ii)  Control Accounts. Pledgor shall not maintain any Securities
Account or Commodity Account that is not a Control Account.

          (iii) Control of Investment Property. Pledgor shall not grant
"control" (as defined in the UCC with respect to any such Investment Property)
over any Investment Property to any Person other than the Collateral Agent and
as contemplated under the Intercreditor Agreement.

     (c)  Additional Collateral; Additional Pledgors. Pledgor hereby covenants
and agrees with the Collateral Agent, on its own behalf and on behalf of the
other Noteholders, that at or prior to the consummation of any transaction
involving Pledgor permitted under Section 7.5.1 of the Note Purchase Agreement,
Pledgor shall (a) deliver to the Collateral Agent with sufficient copies for all
the Noteholders supplements of Schedules A, B and C in substantially the form
attached hereto as Exhibit A (each a "Security Agreement Supplement"), which
shall be in form and substance reasonably acceptable to the Collateral Agent,
together with such additional information as the Collateral Agent may request in
connection therewith and with the security interest and Liens granted hereunder,
and (b) shall cause each new Subsidiary of Pledgor to execute and deliver a
security agreement in the form of this Agreement to the Collateral Agent and to
take all actions required to be taken by a Pledgor hereunder.

Intercreditor Agreement; and (e) Pledgor has not entered into any contract or

                                       8

discretion, to perfect or continue perfected the security interest of the

without limitation, the tax returns of Pledgor, (ii) after the occurrence of an
Event of Default, arrange for verification of Pledgor's Accounts, under

all in accordance with the provisions of Section 6.9 of the Note Purchase
Agreement;

     (b)  promptly furnish to the Collateral Agent (in sufficient copies for all

additional statements and

                                       9



information with respect to the Collateral, and all writings and information
relating to or evidencing any of Pledgor's Accounts (including, without
limitation, computer printouts or typewritten reports listing the mailing
addresses of all present Account Debtors), and (ii) any other writings and
information as the Collateral Agent may request;

     (c)  immediately notify the Collateral Agent and the Noteholders in writing
of any information that Pledgor has or may receive with respect to the
Collateral which information might in any manner materially and adversely affect
the value thereof or the rights of the Collateral Agent or any Noteholder with
respect thereto;

     (d)  maintain the Equipment in good operating condition and repair,
ordinary wear and tear excepted, making all necessary replacements thereof so
that the value and operating efficiency thereof shall at all times be maintained
and preserved, and promptly inform the Collateral Agent of any additions to or
deletions from the Equipment; and

     (e)  upon request of the Collateral Agent, promptly take such action and
promptly make, execute, authorize and deliver all such additional and further
items, deeds, assurances, instruments and any other writings as the Collateral
Agent or the Noteholders may from time to time deem necessary or appropriate,
including, without limitation, financing statements and chattel paper, to carry
into effect the intention of this Agreement or so as to completely vest in and
ensure to the Collateral Agent and the Noteholders their rights hereunder and in
or to the Collateral.

If certificates of title or applications for title are issued or outstanding
with respect to any of Pledgor's Inventory or Equipment, Pledgor shall, upon
request of the Collateral Agent, (i) execute and deliver to the Collateral Agent
a short form security agreement, in form and substance satisfactory to the
Collateral Agent, and (ii) deliver such certificate or application to the
Collateral Agent and cause the interests of the Collateral Agent and the
Noteholders to be properly noted thereon. Pledgor hereby authorizes the
Collateral Agent or the Collateral Agent's designated agent (but without
obligation by the Collateral Agent to do so) to incur Related Expenses (whether
prior to, upon, or subsequent to any Event of Default hereunder), and Pledgor
shall promptly repay, reimburse, and indemnify the Collateral Agent for any and
all Related Expenses. If Pledgor fails to keep and maintain the Equipment in
good operating condition, the Collateral Agent may (but shall not be required
to) so maintain or repair all or any part of the Equipment and the cost thereof
shall be a Related Expense. Pledgor shall pay all Related Expenses to the
Collateral Agent upon demand therefor.

12.  COLLECTIONS AND RECEIPT OF PROCEEDS BY PLEDGOR. Prior to exercise by the
Collateral Agent, on its own behalf and on behalf of the Noteholders, of their
rights under this Agreement, both (a) the lawful collection and enforcement of
all of Pledgor's Accounts, and (b) the lawful receipt and retention by Pledgor
of all Proceeds of all of Pledgor's Accounts and Inventory shall be as the agent
of the Collateral Agent and the Noteholders. Upon written notice to Pledgor from
the Collateral Agent upon the occurrence or during the continuance of a Default,
a Cash Collateral Account shall be established by Pledgor at the direction of
the Collateral Agent and all such lawful collections of Pledgor's Accounts and
such Proceeds of Pledgor's Accounts and Inventory shall be remitted daily by
Pledgor to the Collateral Agent in the form in which they are received by
Pledgor, either by mailing or by delivering such collections and Proceeds to

                                       10



the Collateral Agent, appropriately endorsed for deposit in the Cash Collateral
Account. In the event that such notice is given to Pledgor from the Collateral
Agent, Pledgor shall not commingle such collections or Proceeds with any of
Pledgor's other funds or property, but shall hold such collections and Proceeds
separate and apart therefrom upon an express trust for the Collateral Agent. In
such case, the Collateral Agent may, in its sole discretion, at any time and
from time to time, apply all or any portion of the account balance in the Cash
Collateral Account as a credit against the Debt. If any remittance shall be
dishonored, or if, upon final payment, any claim with respect thereto shall be
made against the Collateral Agent on its warranties of collection, the
Collateral Agent may charge the amount of such item against the Cash Collateral
Account or any other Deposit Account maintained by Pledgor with the Collateral
Agent, and, in any event, retain the same and Pledgor's interest therein as
additional security for the Debt. The Collateral Agent may, in its sole
discretion, at any time and from time to time, release funds from the Cash
Collateral Account to Pledgor for use in Pledgor's business. The balance in the
Cash Collateral Account may be withdrawn by Pledgor upon termination of this
Agreement and payment in full of all of the Debt. At the Collateral Agent's
request after the occurrence of an Event of Default, Pledgor shall cause all
remittances representing collections and Proceeds of Collateral to be mailed to
a lock box in Cleveland, Ohio, to which the Collateral Agent shall have access
for the processing of such items in accordance with the provisions, terms, and
conditions of lock box agreement customary to the Banks' Agent or such other
financial institution as may then be the institution maintaining such lock box
account.

13.  COLLECTIONS AND RECEIPT OF PROCEEDS BY COLLATERAL AGENT.

     (a)  Upon the occurrence and during the continuance of a Default, the
Collateral Agent shall at all times have the right, but not the duty, to collect
and enforce any or all of the Accounts as the Collateral Agent may deem
advisable and, if the Collateral Agent shall at any time or times elect to do so
in whole or in part, the Collateral Agent shall not be liable to Pledgor except
for willful misconduct, if any.

     (b)  Pledgor hereby constitutes and appoints the Collateral Agent, or the
Collateral Agent's designated agent, as Pledgor's attorney-in-fact to exercise,
after the occurrence of an Event of Default, all or any of the following powers
which, being coupled with an interest, shall be irrevocable until the complete
and full payment of all of the Debt:

          (i)   to receive, retain, acquire, take, endorse, assign, deliver,
accept, and deposit, in the Collateral Agent's name or Pledgor's name, any and
all of Pledgor's cash, instruments, chattel paper, documents, Proceeds of
Accounts, Proceeds of Inventory, collection of Accounts, and any other writings
relating to any of the Collateral. Pledgor hereby waives presentment, demand,
notice of dishonor, protest, notice of protest, and any and all other similar
notices with respect thereto, regardless of the form of any endorsement thereof.
Neither the Collateral Agent nor the Noteholders shall be bound or obligated to
take any action to preserve any rights therein against prior parties thereto;

          (ii)  to transmit to Account Debtors, on any or all of Pledgor's
Accounts, notice of assignment to the Collateral Agent, for the benefit of the
Noteholders, thereof and the security interest of the Collateral Agent, for the
benefit of the Noteholders, and to request from

                                       11



such Account Debtors at any time, in the Collateral Agent's name or in Pledgor's
name, information concerning Pledgor's Accounts and the amounts owing thereon;

          (iii) to transmit to purchasers of any or all of Pledgor's Inventory,
notice of the security interest of the Collateral Agent for the benefit of the
Noteholders, and to request from such purchasers at any time, in the Collateral
Agent's name or in Pledgor's name, information concerning Pledgor's Inventory
and the amounts owing thereon by such purchasers;

          (iv)  to notify and require Account Debtors on Pledgor's Accounts and
purchasers of Pledgor's Inventory to make payment of their indebtedness directly
to the Collateral Agent, for the benefit of the Noteholders;

          (v)   to enter into or assent to such amendment, compromise,
extension, release or other modification of any kind of, or substitution for,
the Accounts or any thereof as the Collateral Agent, in its reasonable
discretion, may deem to be advisable;

          (vi)  to enforce the Accounts or any thereof, or any other Collateral,
by suit or otherwise, to maintain any such suit or other proceeding in the
Collateral Agent's own name or in Pledgor's name, and to withdraw any such suit
or other proceeding. Pledgor agrees to lend every assistance requested by the
Collateral Agent in respect of the foregoing, all at no cost or expense to the
Collateral Agent or the Noteholders and including, without limitation, the
furnishing of such witnesses and of such records and other writings as the
Collateral Agent may require in connection with making legal proof of any
Account. Without limiting any other provision hereof, Pledgor agrees to
reimburse the Collateral Agent and the Noteholders in full for all court costs
and reasonable attorneys' fees and every other cost, expense or liability, if
any, incurred or paid by the Collateral Agent or the Noteholders in connection
with the foregoing, which obligation of Pledgor shall constitute Debt, shall be
secured by the Collateral and shall bear interest, until paid, at the default
rate of interest set forth in Section 2.6 of the Note Purchase Agreement; and

          (vii) to accept all collections in any form relating to the
Collateral, including remittances that may reflect deductions, and to deposit
the same, into Pledgor's Cash Collateral Account or, at the option of the
Collateral Agent (subject to the terms of the Intercreditor Agreement) to apply
them as a payment on the Debt.

14.  USE OF INVENTORY AND EQUIPMENT. Until an Event of Default shall occur,
Pledgor may (a) retain possession of and use its Inventory and Equipment in any
lawful manner not inconsistent with this Agreement or with the terms,
conditions, or provisions of any policy of insurance thereon; (b) sell or lease
its Inventory in the ordinary course of business; provided, however, that a sale
or lease in the ordinary course of business does not include a transfer in
partial or total satisfaction of any indebtedness, except for transfers in
satisfaction of partial or total purchase money prepayments by a buyer in the
ordinary course of Pledgor's business; and (c) use and consume raw materials or
supplies, the use and consumption of which are necessary in order to carry on
Pledgor's business.

                                       12



15.  DEFAULT AND REMEDIES.

     15.1 Any of the following shall constitute an Event of Default under this
Agreement: (a) an Event of Default, as defined in the Note Purchase Agreement,
shall occur under the Note Purchase Agreement; (b) any representation, warranty
or statement made by Pledgor in or pursuant to this Agreement or in any other
writing received by the Collateral Agent or the Noteholders in connection with
the Debt shall be false or erroneous in any material respect; or (c) Pledgor
shall fail or omit to perform or observe any agreement made by Pledgor in or
pursuant to this Agreement or in any other writing received by the Collateral
Agent or any Noteholder pursuant hereto.

     15.2 Upon the occurrence of an Event of Default hereunder, and at all times
thereafter, the Collateral Agent, on its own behalf and on behalf of the
Noteholders, shall have the rights and remedies of a secured party under the
UCC, in addition to the rights and remedies provided elsewhere within this
Agreement or in any other writing executed by Pledgor. The Collateral Agent may
require Pledgor to assemble the Collateral, which Pledgor agrees to do, and make
it available to the Collateral Agent at a reasonably convenient place to be
designated by the Collateral Agent. The Collateral Agent may, with or without
notice to or demand upon Pledgor and with or without the aid of legal process,
make use of such force as may be necessary to enter any premises where the
Collateral, or any thereof, may be found and to take possession thereof
(including anything found in or on the Collateral that is not specifically
described in this Agreement, each of which findings shall be considered to be an
accession to and a part of the Collateral) and for that purpose may pursue the
Collateral wherever the same may be found, without liability for trespass or
damage caused thereby to Pledgor. After any delivery or taking of possession of
the Collateral, or any thereof, pursuant to this Agreement, then, with or
without resort to Pledgor or any other Person or property, all of which Pledgor
hereby waives, and upon such terms and in such manner as the Collateral Agent
may deem advisable, the Collateral Agent, in its discretion, may sell, assign,
transfer, deliver or otherwise liquidate and dispose of any of the Collateral at
any time or, from time to time. Any sale or disposition, subject to the
provisions of applicable law, may be made at private or public proceedings. No
prior notice need be given to Pledgor or to any other Person in the case of any
sale or disposition of Collateral that the Collateral Agent determines to be
perishable or to be declining speedily in value or that is customarily sold in
any recognized market, but, in any other case, the Collateral Agent shall give
Pledgor no fewer than ten (10) days' prior notice of either the time and place
of any public sale of the Collateral or of the time after which any private sale
or other intended disposition thereof is to be made. Pledgor waives
advertisement of any such sale and (except to the extent specifically required
by the preceding sentence) waives notice of any kind in respect of any such
sale. At any such public sale, the Collateral Agent or any Noteholder may
purchase the Collateral, or any part thereof, free from any right of redemption,
all of which rights Pledgor hereby waives and releases. After deducting all
Related Expenses, and after paying all claims, if any, secured by liens having
precedence over the Liens granted under this Agreement, the Collateral Agent
shall apply such net proceeds of each such sale to or toward the payment of the
Debt, whether or not then due, as provided in the Note Purchase Agreement. Any
excess, to the extent permitted by law, shall be paid to Pledgor, and the
obligors on the Debt shall remain liable for any deficiency. In addition, the
Collateral Agent shall at all times have the right to obtain new appraisals of
Pledgor or the Collateral, the cost of which shall be paid by Pledgor.

                                       13



16.  MAXIMUM LIABILITY OF PLEDGOR.

     16.1 Limitation of Liability. If, in any action to enforce this Agreement
or any proceeding to allow or adjudicate a claim under this Agreement, a court
of competent jurisdiction determines that enforcement of this Agreement against
Pledgor for the full amount of the Debt is not lawful under, or would be subject
to avoidance under, Section 548 of the United States Bankruptcy Code or any
applicable provision of comparable state law, the liability of Pledgor under
this Agreement shall be limited to the maximum amount lawful and not subject to
avoidance under such law.

     16.2 Debt May Exceed Pledgor's Maximum Liability. Pledgor agrees that the
Debt may at any time and from time to time exceed the maximum amount of the Debt
secured by this Agreement without impairing this Agreement or affecting the
rights and remedies of the Collateral Agent or the Noteholders hereunder.

     16.3 Pledgor's Liability Not Reduced by Payments by Others. No payment or
payments made by Oglebay, Pledgor or any other Person or received or collected
by the Collateral Agent or the Noteholders from Oglebay, Pledgor or any other
Person by virtue of any action or proceeding or any set-off or appropriation or
application at any time or from time to time in reduction of or in payment of
the Debt shall be deemed to modify, reduce, release or otherwise affect the
amount of the Debt secured by this Agreement and this Agreement shall,
notwithstanding any such payment or payments (other than payments made to the
Collateral Agent or the Noteholders by Pledgor or payments received or collected
by the Collateral Agent or the Noteholders from Pledgor), secure the Debt up to
the maximum amount of the Debt secured by this Agreement as set forth above
until the Debt is indefeasibly paid in full in cash.

17.  LIMITATION ON DUTY OF THE COLLATERAL AGENT WITH RESPECT TO THE COLLATERAL.
The powers conferred on the Collateral Agent hereunder are solely to protect its
interest in the Collateral and shall not impose any duty on it to exercise any
such powers. Except for the safe custody of any Collateral in its possession and
the accounting for monies actually received by it hereunder, the Collateral
Agent shall have no duty with respect to any Collateral. The Collateral Agent
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment that is substantially equivalent to that which the Collateral Agent
accords its own property, it being expressly agreed that the Collateral Agent
shall have no responsibility for (a) ascertaining or taking action with respect
to calls, conversions, exchanges, maturities, tenders or other matters relative
to any Pledged Collateral, whether or not the Collateral Agent has or is deemed
to have knowledge of such matters, or (b) taking any necessary steps to preserve
rights against any parties with respect to any Pledged Collateral, but the
Collateral Agent may do so and all expenses incurred in connection therewith
shall be payable by and for the sole account of Pledgor.

18. INTERPRETATION. Each right, power or privilege specified or referred to in
this Agreement is cumulative and in addition to and not in limitation of any
other rights, powers and privileges that the Collateral Agent and the
Noteholders (or any of them) may otherwise have or acquire by operation of law,
by contract or otherwise. No course of dealing by the Collateral Agent or the
Noteholders in respect of, nor any omission or delay by the Collateral Agent or
the

                                       14



Noteholders in the exercise of, any right, power or privilege shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right,
power or privilege preclude any other or further exercise thereof or of any
other right, power or privilege, as the Collateral Agent or the Noteholders may
exercise each such right, power or privilege either independently or
concurrently with others and as often and in such order as the Collateral Agent
and the Noteholders may deem expedient. No waiver, consent or other agreement
shall be deemed to have been made by the Collateral Agent (on its own behalf or
on behalf of the Noteholders) or be binding upon the Collateral Agent (or on the
Noteholders) in any case unless specifically granted by the Collateral Agent in
writing, and each such writing shall be strictly construed. If, at any time, one
or more provisions of this Agreement is or becomes invalid, illegal or
unenforceable in whole or in part, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.
Pledgor hereby authorizes the Collateral Agent to file financing statements with

Agreement may be used as a financing statement. The captions to sections herein
are inserted for convenience only and shall be ignored in interpreting the
provisions of this Agreement.

irrevocably submits to the non-exclusive jurisdiction of any New York state or
federal court sitting in New York, New York, over any action or proceeding
arising out of or relating to this Agreement or any Senior Notes Document, and
Pledgor hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in such New York state or federal court.
Pledgor, on behalf of itself and its Subsidiaries, hereby irrevocably waives, to
the fullest extent permitted by law, any objection it may now or hereafter have
to the laying of venue in any action or proceeding in any such court as well as
any right it may now or hereafter have to remove such action or proceeding, once
commenced, to another court on the grounds of FORUM NON CONVENIENS or otherwise.
Pledgor agrees that a final, nonappealable judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

21. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon Pledgor and
Pledgor's successors and assigns and shall inure to the benefit of, be
enforceable and exercisable by, and be binding upon the Collateral Agent, on its
own behalf and on behalf of the Noteholders and its successors and assigns.
Without limiting the generality of the foregoing, any Noteholder may assign or
otherwise transfer any Senior Note held by it to any other Person as permitted
in

                                       15



the Note Purchase Agreement, and such other Person shall thereupon become vested
with all the benefits in respect thereof granted to the Collateral Agent herein
or otherwise.

22.  TERMINATION. At such time as the Debt has been irrevocably paid in full,
and the Note Purchase Agreement terminated and not replaced by any other similar
agreement with the Noteholders, this Agreement shall terminate and, upon written
request of Pledgor, the Collateral Agent shall promptly execute and deliver to
Pledgor appropriate termination statements. This Agreement and the security
interest herein created in the Collateral shall terminate only if (a) Pledgor
delivers a written request for termination to the Collateral Agent and the
Noteholders, (b) the Debt shall have been paid in full at the time such written
termination is received by the Collateral Agent and the Noteholders, and (c) the
Collateral Agent executes an appropriate termination statement; provided that
the Collateral Agent shall release its Liens in all or a part of the Collateral
that is transferred (as defined in the Note Purchase Agreement) in accordance
with the terms and conditions of the Note Purchase Agreement and the Collateral
Agent shall have received at least 10 Business days prior to the proposed
effective date of any such release (in sufficient copies for all the
Noteholders) documentation and other information satisfactory to the Collateral
Agent that such transfer is executed in compliance with the terms and conditions
of the Note Purchase Agreement.

23.  ENTIRE AGREEMENT. This Agreement, together with the other Security
Documents to which Pledgor is party, integrates all of the terms and conditions
as to Liens in and to the Collateral granted by Pledgor and supersedes all oral
representations and negotiations and prior writings with respect to the subject
matter hereof.

THEREIN AND NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION, AS TRUSTEE.

RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT OR ANY
NOTE OR OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN
CONNECTION HEREWITH OR THE TRANSACTIONS RELATED THERETO.

26.  WAIVER; AMENDMENT.

waived, modified or varied in any manner whatsoever unless in writing duly
signed by Pledgor and the

                                       16



Collateral Agent (and such other percentage of the Noteholders as may be
required by the Note Purchase Agreement). Notwithstanding the foregoing, this
Agreement shall be amended (solely to the extent of replacing 1818 Mezzanine as

Agent and acknowledged in writing by a successor collateral agent, provided that
such acknowledgement shall have the effect of binding such successor collateral
agent to the terms of this Agreement and such successor Collateral Agent shall

Supplement in substantially the form of Exhibit A hereto, Schedules A, B and C
attached to such Security Agreement Supplement shall be incorporated into and
become a part of and supplement Schedules A, B, C and D, respectively, hereto,
and the Collateral Agent may attach such supplemental schedules to such
Schedules, and each reference to such Schedules shall mean and be a reference to
such Schedules as supplemented pursuant to each Security Agreement Supplement.

27.  OBLIGATIONS ABSOLUTE.  The obligations of Pledgor hereunder shall remain in
full force and effect without regard to, and shall not be impaired by, (a) any
bankruptcy, insolvency, reorganization, arrangement, readjustment, composition,
liquidation or the like of Oglebay, Pledgor or any Guarantor; (b) any exercise
or non-exercise, or any waiver of, any right, remedy, power or privilege under

the foregoing.

28.  LIEN Subordination. The security interest and Liens granted hereunder, and
the rights and remedies of the Collateral Agent and the Noteholders under this
Agreement, are subject to the terms of the Intercreditor Agreement. Without

hereby, thereby or otherwise expressly permitted in writing by the Banks' Agent.
In the event of any conflict between the terms and provisions of this Agreement
and the Intercreditor Agreement, the terms and provisions of the Intercreditor
Agreement shall govern and control.

                            Form of Pledge Agreement


PLEDGE AGREEMENT dated as of October __, 2002 by ((Company)) ("Pledgor") and THE
1818 MEZZANINE FUND II, L.P. ("1818 Mezzanine"), as agent (the "Collateral
Agent") for itself and the other Noteholders (as hereinafter defined).

                                    RECITALS:

         Pledgor is a party to that certain Senior Secured Note Purchase
Agreement dated as of October __, 2002 (as amended and in effect from time to
time, the "Note Purchase Agreement"), among Oglebay Norton Company, an Ohio
corporation ("Oglebay"), the Guarantors listed on the signature pages thereto,
1818 Mezzanine and the other Purchasers party thereto. Pursuant to the Note
Purchase Agreement, the Purchasers have agreed to purchase the Senior Notes (as
defined in the Note Purchase Agreement). It is a condition precedent to the
Purchasers purchasing the Senior Notes that Pledgor execute and deliver to the
Collateral Agent this Pledge Agreement for the benefit of the Noteholders and
the Collateral Agent.

         Terms defined in the Note Purchase Agreement and not otherwise defined
in this Agreement are used in this Agreement as defined in the Note Purchase
Agreement. Terms that are defined in Articles 8 and 9 of the UCC (as defined
below) and not otherwise defined herein are used herein as therein defined.

         NOW,THEREFORE, in consideration of the premises contained herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

1.       Definitions. As used herein, the following terms shall have the
         following meanings:

         "Banks' Agent" shall mean KeyBank National Association as Agent for the
Banks under the Intercreditor Agreement.

         "Collateral" shall mean, collectively, the Pledged Securities and each
addition, if any, thereto and each substitution, if any, therefor, in whole or
in part, the certificates representing the Pledged Securities, and all dividends
(whether made in cash or in kind), cash, instruments, chattel paper and other
rights, property or proceeds and products from time to time received, receivable
or otherwise distributed in respect of or in exchange for any and all of the
Pledged Securities, and all proceeds of any of the foregoing, including, without
limitation, cash.

         "Debt" shall mean, collectively, (a) the Senior Notes Obligations
(including, without limitation, the Guaranteed Obligations); (b) each renewal,
exchange, extension, consolidation or refinancing of the foregoing, in whole or
in part; (c) all interest from time to time accruing on any of the foregoing,
and all structuring and financing and other fees pursuant to the Note Purchase
Agreement; (d) all other amounts payable by Oglebay or any Guarantor to the

any other Senior Notes Documents; and (f) all Related Expenses (as defined in
the Security Agreement).

         "Event of Default" shall mean an event or condition that constitutes an
event of default pursuant to Section 9 hereof.

         "Guaranteed Obligations" shall have the meaning ascribed to such term
in the Note Purchase Agreement.

         "Intercreditor Agreement" means the Intercreditor Agreement, dated as
of October ___, 2002, among Oglebay, KeyBank National Association, as Agent, and
the Noteholders, as amended, supplemented and otherwise modified from time to

liability company, institution, trust, estate, government or other agency or
political subdivision thereof or any other entity.

         "Pledged Securities" shall mean all of the shares of capital stock (or
other equity interests) issued by of each Subsidiary of Pledgor owned by

of capital stock (or other equity interests) of each Subsidiary of Pledgor owned
by Pledgor from time to time or acquired by Pledgor in any manner.

         "Security Agreement" shall mean the security agreement dated as of
October __, 2002, executed by Pledgor in favor of the Collateral Agent, as
collateral agent thereunder on its own behalf and on behalf of the other
Noteholders, as amended, supplemented and otherwise modified from time to time
in accordance with its terms.

         "UCC" means the Uniform Commercial Code as from time to time in effect
in the State of New York; provided, however, that, if, by reason of mandatory
provisions of law, any or all of the attachment, perfection or priority of the
Collateral Agent's security interest in any Collateral is governed by the
Uniform Commercial Code as in effect in a jurisdiction other than the State of
New York, the term "UCC" means the Uniform Commercial Code as from time to time
in effect in such other jurisdiction for purposes of the provisions hereof
relating to such attachment, perfection or priority and for the purposes of
definitions related to such provisions; provided, further, that, if the UCC is
amended after the date hereof, such amendment will not be given effect for the
purposes of this Agreement to the extent such amendment would limit or eliminate
any property or asset of a debtor from being Collateral.

Terms used in this Agreement without definition have the meanings ascribed to
such terms in the Note Purchase Agreement. Terms that are defined in Articles 8
and 9 of the UCC and not otherwise defined herein are used herein as therein
defined.

2.       Security Interest. (a) Pledgor hereby pledges and grants to the
Collateral Agent, for its benefit and the ratable benefit of the Noteholders
(including 1818 Mezzanine in its capacity as a Noteholder), a security interest
in the Collateral as security for the Debt. (b) Pledgor authorizes the
Collateral Agent, upon the occurrence or during the continuance of an Event of
Default, to transfer to or to register in the name of the Collateral Agent or
the Collateral Agent's nominee

                                        2



any or all of the Collateral, but the Collateral Agent shall be under no duty to
do so. In addition, the Collateral Agent shall have the right upon written
notice to Pledgor, to exchange certificates or instruments representing or
evidencing Collateral for certificates or instruments of smaller or larger
denominations. Notwithstanding any provision or inference herein or elsewhere to
the contrary, the Collateral Agent shall have no right to vote the Pledged
Securities at any time unless and until there shall have occurred an Event of
Default. (c) Pledgor hereby authorizes the Collateral Agent to file one or more
financing or continuation statements, and amendments thereto, relating to all or
part of the Collateral without the signature of Pledgor where permitted by law.

3.       Pledgor's Representations and Warranties. Pledgor represents and
warrants to the Collateral Agent and each Noteholder as follows:

         3.1   Exhibit A hereto completely and accurately sets forth all
securities constituting the Initial Pledged Securities. Except as indicated on
Exhibit A, each Initial Pledged Security is a "certificated security" (as
defined in the UCC). Pledgor is the legal record and beneficial owner of, and
has good and marketable title to, the Pledged Securities, and the Pledged
Securities are not subject to any pledge, lien, mortgage, hypothecation,
security interest, charge, option, warrant, or other encumbrance whatsoever, nor
to any agreement purporting to grant to any third party a security interest in
the property or assets of Pledgor that would include such Pledged Securities,
except the security interest created by this Agreement or otherwise securing the
Collateral Agent and the Noteholders and the security interests granted by
Pledgor under any syndicated Facility Document in favor of the Banks' Agent and
Banks or as otherwise expressly permitted under the Note Purchase Agreement.

         3.2   All of the Pledged Securities are duly authorized and validly
issued, and are fully paid and non-assessable.

         3.3   Pledgor has full power, authority and legal right to pledge all
of the Pledged Securities pursuant to the terms of this Agreement.

         3.4   No consent, license, permit, approval or authorization, filing or
declaration with any governmental authority, domestic or foreign, and no consent
of any other party, is required to be obtained by Pledgor in connection with the
pledge of the Pledged Securities hereunder, which has not been obtained or made,
and is not in full force and effect.

         3.5   Upon the filing of Form UCC-1 financing statements identifying
the Pledged Securities, the Collateral Agent shall have a valid and perfected
Lien on and security interest in the Pledged Securities, securing payment of the
Debt, subject only to the prior security interest of the Banks' Agent in the
Collateral. As of the date hereof, Pledgor has delivered such certificates
evidencing the Pledged Securities (together with transfer powers, in the form of
Exhibit B hereto, executed in blank) to the Banks' Agent and original transfer
powers executed in blank to the Collateral Agent. Pledgor shall, immediately
upon termination of the Syndicated Credit Agreement, Syndicated Loan Agreement
and any pledges constituting Syndicated Facility Documents, deliver to the
Collateral Agent the certificates evidencing the Pledged Securities and any
other securities then pledged, together with transfer powers duly executed in
blank, whereupon the Collateral Agent shall have a valid and perfected first
priority security interest in

                                        3



such Pledged Shares, free of any adverse claim, securing the Debt. Pledgor
hereby consents to and authorizes each delivery of Pledged Securities by the
Banks' Agent to the Collateral Agent made in accordance or in connection with
the Intercreditor Agreement. Pledgor has delivered to the Collateral Agent a
transaction statement in the form of Exhibit C hereto executed by each
Subsidiary of Pledgor that has issued "uncertificated securities" (as defined in
the UCC) to Pledgor, together with an original copy of Pledgor's instruction to
register the pledge made hereunder of such Pledged Securities in the books and
records of such Subsidiary.

         3.6   The Pledged Securities constitute one hundred percent (100%) of
the outstanding capital stock (or other equity interests) of each Subsidiary of
Pledgor.

         3.7   Pledgor fully anticipates that the Debt will be repaid without
the necessity of selling the Pledged Securities.


         3.8   After adjustments are made for intercompany advances in the
ordinary course of business, Pledgor is Solvent and Pledgor will not cease to be
Solvent as a result of the execution and delivery of (and incurrence of the
obligations under) this Agreement and the other Senior Notes Documents to the
Collateral Agent.

         3.9   If the Pledged Securities are "restricted" within the meaning of
Rule 144, or any amendment thereof, promulgated under the Securities Act of
1933, as amended (the "Securities Act"), as determined by counsel for the
Collateral Agent, Pledgor further represents and warrants that (a) Pledgor has
been the beneficial owner of the Pledged Securities for a period of at least
three years prior to the date hereof, (b) the full purchase price or other
consideration for the Pledged Securities has been paid or given at least three
years prior to the date hereof, and (c) Pledgor does not have a short position
in or any put or other option to dispose of any securities of the same class as
the Pledged Securities or any other securities convertible into securities of
such class.

4.       Event of Default. If an Event of Default shall occur hereunder, the
Collateral Agent, on its own behalf and on behalf of the Noteholders, may, in
the Collateral Agent's discretion and upon such terms and in such manner as the
Collateral Agent shall deem advisable, sell, assign, transfer and deliver or
otherwise liquidate and dispose of the Collateral, or any part thereof, and, in
each case, the Collateral Agent shall apply the net proceeds of the sale thereof
to the Debt, whether or not due, by such allocation as to item and maturity as
the Collateral Agent, in the Collateral Agent's discretion, may deem advisable.
Any sale or disposition, subject to the provisions of applicable law, may be
made at private or public proceedings. No prior notice need be given to Pledgor
or any other Person in the case of any sale of Collateral that the Collateral
Agent determines in good faith to be declining speedily in value or that is
customarily sold at any securities exchange or in the over-the-counter market or
in any other recognized market; but, in any other case, the Collateral Agent
shall give Pledgor not fewer than five Business Days' prior notice of either the
date after which any intended private sale may be made or the time and place of
any intended public sale. Pledgor waives advertisement of sale and, except to
the extent required by the preceding sentence, waives notice of any kind in
respect of any sale. The Collateral Agent shall not be obligated to make any
sale of Pledged Collateral regardless of notice of sale having been given. The
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such

                                        4



sale may, without further notice, be made at the time and place to which it was
so adjourned. At any public sale, the Collateral Agent or any of the Noteholders
may purchase the Collateral, or any part thereof, free from any right of
redemption, which rights are hereby waived and released. Pledgor recognizes that
the Collateral Agent may be unable to effect a public sale of all or part of the
Collateral and may be compelled to resort to one or more private sales to a
restricted group of purchasers who will be obligated to agree, among other
things, to acquire such Collateral for their own account, for investment and not
with a view to the distribution or resale thereof. Pledgor acknowledges that any
such private sales may be at prices and on terms less favorable to the seller
than if sold at public sales and agrees that such private sales shall be deemed
to have been made in a commercially reasonable manner, and that the Collateral
Agent has no obligation to delay sale of any such Collateral for the period of
time necessary to permit the issuer of such Collateral to register such
Collateral for public sale under the Securities Act.

5.       Term of Agreement. Irrespective of any action, omission or course of
dealing whatever by the Collateral Agent or the Noteholders, this Agreement
shall remain in full force and effect until the Debt shall have been paid in
full. Without limiting the generality of the foregoing, Pledgor (a) agrees that
neither the Collateral Agent nor any Noteholder shall have any duty to make any
presentment or collection, or to preserve any right of any kind, with reference
to the Collateral, and (b) agrees that the Collateral Agent and the Noteholders
shall at all times have the right to grant any indulgence to Oglebay and to deal
in any other manner with Oglebay, including the granting of any extension,
renewal or increase of the Debt or any part thereof, the increase or decrease of
any rate of interest, the forbearance from exercising any right, power, or
privilege, including any right to demand security, the release of, or
forbearance from proceeding against, any security or any obligor, the effecting
of any other release, compromise or settlement, the substitution of security
(even if of a different character or value), and (c) waives notice of the
creation of any Debt, of any default under any Note or other instrument
evidencing the Debt or any part thereof, of any act, omission, or course of
dealing by the Collateral Agent and the Noteholders, and any other notice to
which Pledgor might be entitled to but for the within waiver. This Agreement and
the security interest herein created in the Collateral shall terminate only if
(a) Pledgor delivers a written request for termination to the Collateral Agent
and the Noteholders, (b) the Debt shall have been paid in full at the time such
written termination is received by the Collateral Agent and the Noteholders, and
(c) the Collateral Agent executes an appropriate termination statement; provided
that the Collateral Agent shall release its Liens in all or a part of the
Collateral that is transferred (as defined in the Note Purchase Agreement) in
accordance with the terms and conditions of the Note Purchase Agreement and the
Collateral Agent shall have received [at least 10 Business days prior to the
proposed effective date of any such release] (in sufficient copies for all the
Noteholders) documentation and other information satisfactory to the Collateral
Agent that such transfer is executed in compliance with the terms and conditions
of the Note Purchase Agreement.

6.       Additional Covenants of Pledgor.

         6.1   Pledgor covenants and agrees to defend the right, title and
security interest of the Collateral Agent and the Noteholders in and to the
Pledged Securities and the proceeds thereof, and to maintain and preserve the
lien and security interest provided for by this Agreement against the claim and
demands of all Persons, so long as this Agreement shall remain in effect.

                                        5



         6.2   Subject to the terms of the Intercreditor Agreement and the Note
Purchase Agreement, including, without limitation, Section 7.5.2 thereof,
Pledgor covenants and agrees not to sell, assign, transfer, exchange, or
otherwise dispose of, or grant any option with respect to, or create, incur or
permit to exist any pledge, lien, mortgage, hypothecation, security interest,
charge, option or any other encumbrance with respect to any of the Pledged
Securities, or any interest therein, or any proceeds thereof, except for the
lien and security interest provided for by this Agreement and any security
agreement securing only the Collateral Agent and the Noteholders.

         6.3   Pledgor covenants and agrees (a) to cooperate, in good faith,
with the Collateral Agent and the Noteholders and to do or cause to be done all
such other acts as may be necessary to enforce the rights of the Collateral
Agent and the Noteholders under this Agreement, (b) not to take any action, or
to fail to take any action that would be adverse to the interest of the
Collateral Agent and the Noteholders in the Collateral and hereunder, (c) to
make any sale or sales of any portion or all of the Pledged Securities valid and
binding and in compliance with any and all applicable laws, regulations, orders,
writs, injunctions, decrees or awards of any and all courts, arbitrators or
governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sale or sales at Pledgor's expense, and (d) (i) after the occurrence of
an Event of Default, if requested by the Collateral Agent, to deliver promptly
upon such request to the Collateral Agent (i) a supplement hereto, duly executed
by Pledgor, in substantially the form of Exhibit D hereto (each a "Pledge
Agreement Supplement"), in respect of such additional Pledged Securities, and
(ii) in any and all cases, either (a) with respect to any certificated
securities, the certificates evidencing any additional Pledged Securities
purchased or acquired by Pledgor after the date hereof, together with transfer
powers thereto duly endorsed in blank, but only to the extent that the delivery
of such certificates and transfer powers is required by Section 3.5 above, or
(b) (1) in the case of any uncertificated securities not maintained in a
securities account, a transaction statement in the form of Exhibit C hereto
executed by the issuer of such uncertificated securities, together with an
original copy of Pledgor's instruction to register the pledge of such Pledged
Securities and (2) for any other investment property, a control agreement in
form and substance reasonably acceptable to the Collateral Agent with respect to
such additional Pledged Securities.

7.       Events of Default. An "Event of Default" shall exist hereunder if (a)
the Debt, or any portion thereof, shall not be paid in full when due and
payable, whether due by lapse of time or acceleration of maturity or otherwise,
(b) an Event of Default, as defined in the Note Purchase Agreement, shall exist
under the Note Purchase Agreement, (c) Pledgor shall fail to fully perform or
omit to perform in any material respect any agreement or other provision
contained or referred to in this Agreement, or (d) any representation, warranty
or statement made in or pursuant to this Agreement, shall be false or erroneous
in any material respect.

8.       Attorney-in-Fact. Pledgor hereby authorizes and empowers the Collateral
Agent, on its own behalf and on behalf of the Noteholders, to make, constitute
and appoint any officer or agent of the Collateral Agent as the Collateral Agent
may select, in its exclusive discretion, as Pledgor's true and lawful
attorney-in-fact, with the power to endorse Pledgor's name on all applications,
documents, papers and instruments necessary for the Collateral Agent to take
actions with respect to the Collateral after the occurrence of an Event of
Default, including, without limitation, actions necessary for the Collateral
Agent to assign, pledge, convey or

                                        6



otherwise transfer title in or dispose of the Collateral to any Person. Pledgor
ratifies all that such attorney shall lawfully do or cause to be done by virtue
hereof. This power of attorney shall be irrevocable for the life of this
Agreement.

9.       Limitation on Duty of the Collateral Agent with Respect to the
Collateral.


The powers conferred on the Collateral Agent hereunder are solely to protect its
interest in the Collateral and shall not impose any duty on it to exercise any
such powers. Except for the safe custody of any Collateral in its possession and
the accounting for monies actually received by it hereunder, the Collateral
Agent shall have no duty with respect to any Collateral. The Collateral Agent
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment that is substantially equivalent to that which the Collateral Agent
accords its own property, it being expressly agreed that the Collateral Agent
shall have no responsibility for (a) ascertaining or taking action with respect
to calls, conversions, exchanges, maturities, tenders or other matters relative
to any Pledged Collateral, whether or not the Collateral Agent has or is deemed
to have knowledge of such matters, or (b) taking any necessary steps to preserve
rights against any parties with respect to any Pledged Collateral, but the
Collateral Agent may do so and all expenses incurred in connection therewith
shall be payable by and for the sole account of Pledgor.

10.      Maximum Liability of Pledgor.

         10.1  Limitation of Liability. If, in any action to enforce this
Agreement or any proceeding to allow or adjudicate a claim under this Agreement,
a court of competent jurisdiction determines that enforcement of this Agreement
against Pledgor for the full amount of the Debt is not lawful under, or would be
subject to avoidance under, Section 548 of the United States Bankruptcy Code or
any applicable provision of comparable state law, the liability of Pledgor under
this Agreement shall be limited to the maximum amount lawful and not subject to
avoidance under such law.

         10.2  Debt May Exceed Pledgor's Maximum Liability. Pledgor agrees that
the Debt may at any time and from time to time exceed the maximum amount of the
Debt secured by this Agreement without impairing this Agreement or affecting the
rights and remedies of the Collateral Agent or the Noteholders hereunder.

         10.3  Pledgor's Liability Not Reduced by Payments by Others. No payment
or payments made by Oglebay, Pledgor or any other Person or received or
collected by the Collateral Agent or the Noteholders from Oglebay, Pledgor or
any other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to time in reduction of or
in payment of the Debt shall be deemed to modify, reduce, release or otherwise
affect the amount of the Debt secured by this Agreement and this Agreement
shall, notwithstanding any such payment or payments (other than payments made to
the Collateral Agent or the Noteholders by Pledgor or payments received or
collected by the Collateral Agent or the Noteholders from Pledgor), secure the

11.      Costs and Expenses. If Pledgor fails to comply with any of its
obligations hereunder, the Collateral Agent may do so in Pledgor's name or in
the Collateral Agent's name, but at Pledgor's expense, and Pledgor hereby agrees
to reimburse in full the Collateral Agent and the Noteholders all costs and
expenses, including reasonable attorneys' fees, incurred by the Collateral Agent
and the Noteholders in connection with protecting, defending and maintaining the
Collateral. Without limiting the foregoing, any and all reasonable fees, costs
and expenses, of whatever kind or nature, including the reasonable attorneys'
fees and expenses incurred in connection with the filing or recording of any
documents (including all taxes in connection therewith) in public offices, the
payment or discharge of any taxes, maintenance fees, encumbrances or otherwise
protecting, maintaining or preserving the Collateral, or in defending or
prosecuting any actions or proceedings arising out of or related to the
Collateral, shall be borne and paid by Pledgor on demand by the Collateral
Agent.

12.      Notice. All notices, requests, demands and other communications
provided for hereunder shall be in writing and, if to Pledgor, mailed or
delivered to it, addressed to it at the address specified on the signature page
of this Agreement, if to the Collateral Agent or a Noteholder, mailed or

demands and other communications provided for hereunder shall be given by
overnight delivery or first class mail with postage prepaid by registered or
certified mail, addressed as aforesaid, or sent by facsimile with telephonic
confirmation of receipt, except that notices pursuant to any of the provisions
hereof shall not be effective until received.

13.      No Subrogation. Pledgor shall have no rights against Oglebay with
respect to this Agreement or the Collateral and shall have no right of
subrogation and hereby waives any right to enforce any remedy which the
Collateral Agent or the Noteholders now has or may hereafter have against
Oglebay, any endorser or any other guarantor of all or any part of the Debt, and
Pledgor hereby waives all setoffs and counterclaims and all presentments,
demands for performance, notices of nonperformance, protests, notices of

Pledgor further waives all notices of the existence, creation or incurring of
any new or additional indebtedness arising either in connection with additional

principal amount, or any portion thereof, and/or any interest on any instrument
or document evidencing all or any part of the Debt is due, notices of any and
all proceedings to collect from the maker, any endorser or any other guarantor

permitted by law, notices of exchange, sale, surrender or other handling of any
security or collateral given to the Collateral Agent or any Noteholder to secure
payment of the Debt.

14.      Interpretation. Each right, power or privilege specified or referred
to in this Agreement is in addition to any other rights, powers and privileges
that the Collateral Agent and the Noteholders (or any of them) may have or
acquire by operation of law, by other contract or otherwise. No course of
dealing in respect of, nor any omission or delay in the exercise of, any right,
power or privilege by the Collateral Agent and the Noteholders shall operate as
a waiver thereof, nor shall any single or partial exercise thereof preclude any
further or other exercise thereof or of any other, as each right, power or
privilege may be exercised by the Collateral Agent and the Noteholders either
independently or concurrently with other rights, powers and

                                        8



privileges and as often and in such order as the Collateral Agent and the
Noteholders may deem expedient. No waiver, consent or other agreement granted by
the Collateral Agent (on its own behalf or on behalf of the Noteholders) in
respect of this Agreement shall be binding upon the Collateral Agent or the
Noteholders unless specifically granted in writing, which writing shall be
strictly construed.

15.      Assignment and Successors. This Agreement shall not be assigned by
Pledgor without the prior written consent of the Collateral Agent. This
Agreement shall bind the successors and permitted assigns of Pledgor and shall
benefit the respective successors and assigns of the Collateral Agent and the
Noteholders. Without limiting the generality of the foregoing, any Noteholder
may assign or otherwise transfer any Senior Note held by it to any other Person
as permitted in the Note Purchase Agreement, and such other Person shall
thereupon become vested with all the benefits in respect thereof granted to the
Collateral Agent herein or otherwise.

16.      Governing Law. The provisions of this Agreement, and the respective
rights and duties of Pledgor, the Collateral Agent and the Noteholders
hereunder, shall be governed by the laws of the State of New York, without
regard to principles of conflict of laws.

17.      Severability. If, at any time, one or more provisions of this Agreement
is or becomes invalid, illegal or unenforceable in whole or in part, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

18.      DESIGNATED SENIOR INDEBTEDNESS. THE INDEBTEDNESS EVIDENCED BY THIS
AGREEMENT, THE NOTE PURCHASE AGREEMENT, EACH OF THE SENIOR NOTES, AND EACH OTHER
SENIOR NOTES DOCUMENT IS AND SHALL AT ALL TIMES CONSTITUTE "DESIGNATED SENIOR
INDEBTEDNESS" UNDER THE PROVISIONS OF THAT CERTAIN INDENTURE, DATED AS OF
FEBRUARY 1, 1999, AS AMENDED, AMONG OGLEBAY NORTON COMPANY, THE GUARANTORS NAMED
THEREIN AND NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION, AS TRUSTEE.

19.      JURY TRIAL WAIVER. PLEDGOR WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE
IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AMONG
PLEDGOR, COLLATERAL AGENT AND THE NOTEHOLDERS, OR ANY OF THEM, ARISING OUT OF,
IN CONNECTION WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
AMONG THEM IN CONNECTION WITH THIS AGREEMENT OR ANY NOTE OR OTHER INSTRUMENT,
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION THEREWITH OR THE
TRANSACTIONS RELATED THERETO.

20.      Waiver; Amendment.

         20.1 None of the terms and conditions of this Agreement may be changed,
waived, modified or varied in any manner whatsoever unless in writing duly
signed by Pledgor and the Collateral Agent (and such other percentage of the
Noteholders as may be required by the Note Purchase Agreement). Notwithstanding
the foregoing, this Agreement shall be amended (solely to the extent of
replacing 1818 Mezzanine as the Collateral Agent) by a written notice delivered

                                        9



to Pledgor by the Collateral Agent and acknowledged in writing by a successor
collateral agent; provided that such acknowledgement shall have the effect of
binding such successor collateral agent to the terms of this Agreement and such
successor Collateral Agent shall be, in its individual capacity, a Noteholder.)

         20.2  Upon the execution and delivery by Pledgor of a Pledge Agreement
Supplement, Exhibit A attached to such Pledge Agreement Supplement shall be
incorporated into and become a part of and supplement Exhibit A hereto, and the
Collateral Agent may attach such supplemental exhibit to such Exhibit A; and
each reference to such Exhibit shall mean and be a reference to such Exhibits as
supplemented pursuant to each Pledge Agreement Supplement.

21.      Obligations Absolute. The obligations of Pledgor hereunder shall remain
in full force and effect without regard to, and shall not be impaired by, (a)
any bankruptcy, insolvency, reorganization, arrangement, readjustment,
composition, liquidation or the like of Oglebay, Pledgor or any Guarantor; (b)
any exercise or non-exercise, or any waiver of, any right, remedy, power or
privilege under or in respect of this Agreement or any other Senior Notes
Document; or (c) any amendment to or modification of any Senior Notes Document
or any security for any of the Debt whether or not Pledgor shall have notice or
knowledge of any of the foregoing.

22.      Lien Subordination

The pledge made and the security interest and Liens granted hereunder, and the
rights and remedies of the Collateral Agent hereunder are subject to the terms
of the Intercreditor Agreement. Without limiting, and in furtherance of the
foregoing, the Collateral Agent shall not exercise its rights under Sections
2(b) and 4 hereof so long as the Intercreditor Agreement is in effect, except as
expressly permitted thereby or otherwise expressly permitted in writing by the
Banks' Agent. In the event of any conflict between the terms and provisions of
this Agreement and the Intercreditor Agreement, the terms and provisions of the
Intercreditor Agreement shall govern and control.

                                       10



         IN WITNESS WHEREOF, each of Pledgor and the Collateral Agent has caused
this Agreement to be duly executed and delivered by its officer thereunto duly
authorized as of the date first above written.

              Form of Collateral Assignment and Security Agreement


         COLLATERAL ASSIGNMENT AND SECURITY AGREEMENT dated as of October __,
2002 by ((Company)) ("Pledgor"), and THE 1818 MEZZANINE FUND II, L.P. ("1818
Mezzanine"), as collateral agent (together with its successors and assigns in
such capacity, the "Collateral Agent") for itself and the other Noteholders (as
hereinafter defined).

                                    RECITALS:


         Pledgor is a party to that certain Senior Secured Note Purchase
Agreement dated as of October __, 2002 (as amended and in effect from time to
time, the "Note Purchase Agreement"), among Oglebay Norton Company, an Ohio
corporation ("Oglebay"), the Guarantors listed on the signature pages thereto,
1818 Mezzanine and the other Purchasers party thereto. Pursuant to the Note
Purchase Agreement, the Purchasers have agreed to purchase the Senior Notes (as
defined in the Note Purchase Agreement). It is a condition precedent to the
Purchasers purchasing the Senior Notes that Pledgor execute and deliver to the
Collateral Agent this Collateral Assignment and Security Agreement for the
benefit of the Noteholders and the Collateral Agent.

         Terms defined in the Note Purchase Agreement and not otherwise defined
in this Agreement are used in this Agreement as defined in the Note Purchase
Agreement. Terms that are defined in Articles 8 and 9 of the UCC (as defined
below) and not otherwise defined herein are used herein as therein defined.

         NOW, THEREFORE, in consideration of the premises contained herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

         1. Grant of Security Interest. To secure the Debt, as hereinafter
defined, Pledgor hereby grants to the Collateral Agent, for itself in its
capacity as the Collateral Agent hereunder and for the ratable benefit of the
Noteholders (including 1818 Mezzanine in its capacity as a Noteholder), subject
to Section 9 hereof, a security interest in and to all of Pledgor's right title
and interest in and to the following (the "Collateral"):

            (a) The United States patents, patent application, and patent
licenses set forth in Schedule A hereto (as such Schedule A may be supplemented
from time to time by supplements to this Agreement, each such supplement being
in substantially the form of Appendix A hereto (an "Collateral Assignment and
Security Agreement Supplement"), executed and delivered by Pledgor to the
Collateral Agent from time to time), together with all reissues, divisions,
continuations, continuations-in-part, extensions and reexaminations thereof, and
all rights therein provided by international treaties or conventions (the
"Listed Patents");

            (b) The United States trademark and service mark registrations,
applications, and licenses set forth in Schedule B hereto (as such Schedule B
may be supplemented from time to time by Collateral Assignment and Security
Agreement Supplements executed and delivered



by Pledgor to the Collateral Agent from time to time), and all goodwill
associated therewith (the "Listed Marks");

            (c) The copyrights, United States copyright registrations and
applications and copyright licenses set forth in Schedule C hereto (as such
Schedule C may be supplemented from time to time by Collateral Assignment and
Security Agreement Supplements executed and delivered by Pledgor to the
Collateral Agent from time to time) (the "Listed Copyrights");

            (d) any and all claims for damages for past, present and future
infringement, misappropriation or breach with respect to the Listed Patents,
Listed Trademarks and Listed Copyrights, with the right, but not the obligation,
to sue for and collect, or otherwise recover, such damages; and

            (e) any and all proceeds of the foregoing.

         2. Obligations Secured.

            (a) The obligations secured by this Agreement (collectively, the
"Debt") are the payment and performance of, collectively, collectively, (a) the
Senior Notes Obligations (including, without limitation, the Guaranteed
Obligations); (b) each renewal, exchange, extension, consolidation or
refinancing of the foregoing, in whole or in part; (c) all interest from time to
time accruing on any of the foregoing, and all structuring and financing and
other fees pursuant to the Note Purchase Agreement; (d) all other amounts
payable by Oglebay or any Guarantor to the Collateral Agent or any Noteholder
pursuant to the Note Purchase Agreement or any other Senior Notes Documents; and
(f) all Related Expenses (as defined in that certain Security Agreement made by
Pledgor to the Collateral Agent dated as of October __, 2002 (as amended,
amended and restated, supplemented or otherwise modified from time to time, the
"Security Agreement").

         3. Warranties and Representations. Pledgor represents and warrants to
the Collateral Agent and the Noteholders that each of the following statements
is true and complete:

            (a) Pledgor owns the Collateral and, whether the same are registered
or unregistered, no such Collateral has been adjudged invalid or unenforceable.
The Listed Marks constitute all the marks and applications for marks registered
in the United States Patent and Trademark Office that Pledgor presently owns or
uses in connection with its business. The Listed Patents constitute all the
patents and applications for patents that Pledgor owns or uses in connection
with its business, and the Listed Copyrights constitute all registrations of
copyrights and applications for copyright registrations that Pledgor owns or
uses in connection with its business.

            (b) The Collateral is valid and enforceable.

            (c) Pledgor has no knowledge of any claim that the use of any of the
Collateral does or may violate the rights of any third person.

            (d) Except for the liens granted in this Agreement or permitted by
the Intercreditor Agreement and the Note Purchase Agreement, Pledgor is the sole
and exclusive

                                       2



owner of the entire and unencumbered right, title and interest in and to the
Collateral, free and clear of any liens, charges and encumbrances, including,
without limitation, pledges, assignments, licenses, registered user agreements
and covenants by Pledgor not to sue third persons.

            (e) Pledgor has full power, authority and legal right to pledge the
Collateral and enter into this Agreement and perform its terms.

            (f) Pledgor has used, and will continue to use, for the duration of
this Agreement, proper statutory notice in connection with its use of the
Collateral, except where the failure to do so will not have a material adverse
effect.

         4. Right to Use. Pledgor hereby grants to the Collateral Agent a
royalty free license to use any Marks, Patents, Copyrights, for purposes of
manufacturing, selling and otherwise liquidating Collateral, subject to the
condition that the Collateral Agent shall not exercise such license except after
an Event of Default (as that term is defined in Section 9 of this Agreement).
Pledgor shall not enter into any agreement which is inconsistent with Pledgor's
obligations under this Agreement and shall not otherwise sell or assign its
interest in, or grant any license or sublicense in respect of, the Collateral
without the Collateral Agent's prior written consent. Absent such prior written
consent, any attempted sale or license is null and void.

         5. Right to Inspect. Pledgor hereby grants to the Collateral Agent and
its employees and agents the right to visit and inspect Pledgor's properties and
records and to otherwise exercise all rights and privileges of the Noteholders
set forth and as provided in Section 6.9 of the Note Purchase Agreement, at
Pledgor's expense.

         6. Standard Patent and Trademark Use.

         Pledgor shall not use the Collateral in any manner that would
jeopardize the validity or legal status thereof. Pledgor shall comply with all
patent marking requirements as specified in 35 U.S.C. (S)287. Pledgor shall
further conform its usage of any trademarks to standard trademark usage,
including, but not limited to, using the trademark symbols (r), (TM), and (SM)
where appropriate.

         7. [INTENTIONALLY OMITTED]

         8. Event of Default.

            (a) The occurrence of any of the following shall constitute an
"Event of Default" under this Agreement:

                (i)  If an Event of Default, as defined in the Note Purchase
Agreement, shall occur under the Note Purchase Agreement; or

                (ii) If Pledgor shall fail to perform any obligation of Pledgor
to be performed under this Agreement and the same shall not have been fully
corrected within thirty (30) days after the giving of written notice thereof to
Pledgor by the Collateral Agent.

                                        3



              (b) If any Event of Default shall have occurred, Pledgor
irrevocably grants to the Collateral Agent, on behalf of the Noteholders, to
exercise such rights and remedies as allowed by law. Without limiting the
generality of the foregoing, the Collateral Agent may take any or all of the
following actions: (i) declare the entire right, title and interest of Pledgor
in and to the Collateral, together with all patent, copyright and trademark
rights and rights of protection to the same, vested in the Collateral Agent for
the benefit of the Noteholders, in which event such rights, title and interest
shall immediately vest, in the Collateral Agent for the benefit of the
Noteholders, and the Collateral Agent shall be entitled to exercise the power of
attorney referred to in Section 13 hereof to execute, cause to be acknowledged
and notarized and record said absolute assignment with the applicable agency;
and (ii) immediately sell at public or private sale, in a commercially
reasonable manner, or otherwise realize upon all or, from time to time, any of
the Collateral together with the associated goodwill, or any interest which
Pledgor may have therein, and, after deducting from the proceeds of sale or
other disposition of the Collateral all expenses (including all reasonable
expenses for attorneys' and brokers' fees and other legal services), the
Collateral Agent shall apply the residue of such proceeds against payment of the
Debt for the benefit of the Noteholders. Any remainder of the proceeds, after
payment in full of the Debt and to the extent permitted by law, shall be paid to
Pledgor, and the obligors of the Debt shall remain liable for any deficiency.
Notice of any sale or other disposition of the Collateral shall be given to
Pledgor at least five (5) business days before the time of any intended public
or private sale or other disposition of the Collateral is to be made, which
Pledgor hereby agrees shall be reasonable notice of such sale or other
disposition. At any such sale or other disposition, the Collateral Agent or any
Noteholder may, to the extent permissible under applicable law, purchase the
whole or any part of the Collateral sold, free from any right of redemption on
the part of Pledgor, which right is hereby waived and released.

         9.   Termination. At such time as the Debt has been irrevocably paid in
full, and the Note Purchase Agreement terminated and not replaced by any other
similar agreement with the Noteholders, this Agreement shall terminate and the
Collateral Agent shall execute and deliver to Pledgor all deeds, assignments,
and other instruments as may be necessary or proper to release the Collateral
Agent's security interest in and assignment of the Collateral and to re-vest in
Pledgor full title to the Collateral, subject to any disposition thereof which
may have been made by the Collateral Agent pursuant hereto. This Agreement and
the security interest herein created in the Collateral shall terminate only if
(a) Pledgor delivers a written request for termination to the Collateral Agent
and the Noteholders, (b) the Debt shall have been paid in full at the time such
written termination is received by the Collateral Agent and the Noteholders, and
(c) the Collateral Agent executes an appropriate termination statement; provided
that the Collateral Agent shall release its Liens in all or a part of the
Collateral that is transferred (as defined in the Note Purchase Agreement) in
accordance with the terms and conditions of the Note Purchase Agreement and the
Collateral Agent shall have received at least 10 Business days prior to the
proposed effective date of any such release (in sufficient copies for all the
Noteholders) documentation and other information satisfactory to the Collateral
Agent that such transfer is executed in compliance with the terms and conditions
of the Note Purchase Agreement.

         10.  Maintaining Collateral, Attorneys' Fees, Costs and Expenses.
Pledgor shall have the obligation and duty to perform all acts necessary to
maintain or preserve the Collateral, provided that Pledgor shall not be
obligated to maintain any Collateral in the event Pledgor determines, in the
reasonable business judgment of Pledgor, that the maintenance of such

                                       4



Collateral is no longer necessary in Pledgor's business. Any and all reasonable
fees, costs and expenses, of whatever kind or nature, including, without
limitation, the attorneys' fees and legal expenses incurred by the Collateral
Agent and the Noteholders in connection with the amendment and enforcement of
this Agreement, all renewals, required affidavits and all other documents
relating hereto and the consummation of this transaction, the filing or
recording of any documents (including all taxes in connection therewith) in
public offices, the payment or discharge of any taxes, counsel fees, maintenance
fees, encumbrances or otherwise protecting, maintaining or preserving the
Collateral, or in defending or prosecuting any actions or proceedings arising
out of or related to the Collateral, shall be borne and paid by Pledgor, upon
demand by the Collateral Agent, and, until so paid, shall be added to the
principal amount of the Debt.

         11. Pledgor's Obligations to Prosecute. Except as otherwise agreed to
by the Collateral Agent in writing, Pledgor shall have the duty to prosecute
diligently any patent application or trademark application pending as of the
date of this Agreement or thereafter until the Debt shall have been paid in
full, to file and prosecute opposition and cancellation proceedings and to do
any and all acts which are necessary or desirable to preserve and maintain all
rights in the Collateral, including, but not limited to, payment of any
maintenance fees. Any expenses incurred in connection with the Collateral shall
be borne by Pledgor. Pledgor shall not abandon any Collateral without the prior
written consent of the Collateral Agent, unless such abandonment will not have a
material adverse effect on Pledgor and the conduct of Oglebay's and Pledgor's
business.

         12. The Collateral Agent's Rights to Enforce. Pledgor shall have the
right to bring any opposition proceedings, cancellation proceedings or lawsuit
in its own name to enforce or protect the Collateral. The Collateral Agent and
the Noteholders shall have the right, but shall have no obligation, to join in
any such action. Pledgor shall promptly, upon demand, reimburse and indemnify
the Collateral Agent and the Noteholders for all damages, costs and expenses,
including attorneys' fees incurred by the Collateral Agent in connection with
the provisions of this Section 12, in the event the Collateral Agent and the
Noteholders elect to join in any such action commenced by Pledgor.

         13. Power of Attorney. Pledgor hereby authorizes and empowers the
Collateral Agent, on behalf of the Noteholders, to make, constitute and appoint
any officer or agent of the Collateral Agent as the Collateral Agent may select,
in its exclusive discretion, as Pledgor's true and lawful attorney-in-fact, with
the power to endorse, after the occurrence of an Event of Default, Pledgor's
name on all applications, documents, papers and instruments necessary for the
Collateral Agent to use the Collateral, or to grant or issue any exclusive or
non exclusive license under the Collateral to any third party, or necessary for
the Collateral Agent to assign, pledge, convey or otherwise effect an absolute
assignment of all right, title and interest in each Mark, Patent and Copyright,
together with associated goodwill, to the Collateral Agent or to a third party
or parties, and to record the same with the United States Patent and Trademark
Office or the United States Copyright Office. Pledgor hereby ratifies all that
such attorney shall lawfully do or cause to be done by virtue hereof. This power
of attorney shall be irrevocable for the life of this Agreement.

                                        5



      14.  The Collateral Agent's Right to Perform Obligations. If Pledgor fails
to comply with any of its obligations under this Agreement, the Collateral
Agent, on behalf of the Noteholders, may, but is not obligated to, do so in
Pledgor's name or in the Collateral Agent's name, but at Pledgor's expense, and
Pledgor hereby agrees to reimburse the Collateral Agent on demand in full for
all expenses, including reasonable attorneys' fees, incurred by the Collateral
Agent in protecting, defending and maintaining the Collateral.

      15.  Additional Documents. Pledgor shall, upon written request of the
Collateral Agent, enter into such additional documents or instruments as may be
required by the Collateral Agent in order to effectuate, evidence or perfect the
Collateral Agent's interests in the Collateral as evidenced by this Agreement.

      16.  New Collateral. If, before the Debt shall have been satisfied in
full, Pledgor shall obtain rights to any new Collateral, the provisions of
Section 1 shall automatically apply thereto as if the same were identified on
Schedules A, B and C (as applicable) as of the date hereof and Pledgor shall
give the Collateral Agent prompt written notice thereof in the form of a
Collateral Assignment and Security Agreement Supplement.

      17.  Modification for New Collateral. Pledgor hereby authorizes the
Collateral Agent to modify this Agreement by amending Schedules A, B and C (as
applicable) to include any future Collateral as contemplated by Sections 1 and
16 hereof and, at the Collateral Agent's request, Pledgor shall execute any
documents or instruments required by the Collateral Agent in order to modify
this Agreement as provided in this Section 17, provided that any such
modification to Schedules A, B and C shall be effective without the signature of
Pledgor.

      18.  No Waiver. No course of dealing between Pledgor and the Collateral
Agent and the Noteholders, nor any failure to exercise, nor any delay in
exercising, on the part of the Collateral Agent or the Noteholders, any right,
power or privilege hereunder, under any of the Loan Documents, or any other
document executed in connection with any of the foregoing ("Documents") shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or thereunder preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.

      19.  Limitation on Duty of the Collateral Agent with Respect to the
Collateral.

The powers conferred on the Collateral Agent hereunder are solely to protect its
interest in the Collateral and shall not impose any duty on it to exercise any
such powers. Except for the safe custody of any Collateral in its possession and
the accounting for monies actually received by it hereunder, the Collateral
Agent shall have no duty with respect to any Collateral. The Collateral Agent
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment that is substantially equivalent to that which the Collateral Agent
accords its own property, it being expressly agreed that the Collateral Agent
shall have no responsibility for taking any necessary steps to preserve rights
against any parties with respect to any Collateral, but the Collateral Agent may
do so and all expenses incurred in connection therewith shall be payable by and
for the sole account of Pledgor.



                                        6



      20.  Maximum Liability of Pledgor.

           (a)   Limitation of Liability. If, in any action to enforce this
Agreement or any proceeding to allow or adjudicate a claim under this Agreement,
a court of competent jurisdiction determines that enforcement of this Agreement
against Pledgor for the full amount of the Debt is not lawful under, or would be
subject to avoidance under, Section 548 of the United States Bankruptcy Code or
any applicable provision of comparable state law, the liability of Pledgor under
this Agreement shall be limited to the maximum amount lawful and not subject to
avoidance under such law.

           (b)   Debt May Exceed Pledgor's Maximum Liability. Pledgor agrees
that the Debt may at any time and from time to time exceed the maximum amount of
the Debt secured by this Agreement without impairing this Agreement or affecting
the rights and remedies of the Collateral Agent or the Noteholders hereunder.

           (c)   Pledgor's Liability Not Reduced by Payments by Others. No
payment or payments made by Oglebay, Pledgor or any other Person or received or
collected by the Collateral Agent or the Noteholders from Oglebay, Pledgor or
any other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to tine in reduction of or
in payment of the Debt shall be deemed to modify, reduce, release or otherwise
affect the amount of the Debt secured by this Agreement and this Agreement
shall, notwithstanding any such payment or payments (other than payments made to
the Collateral Agent or the Noteholders by Pledgor or payments received or
collected by the Collateral Agent or the Noteholders from Pledgor), secure the
Debt up to the maximum amount of the Debt secured by this Agreement as set forth
above until the Debt is indefeasibly paid in full in cash.

      21.  Remedies Cumulative. All of the rights and remedies of the Collateral
Agent and the Noteholders with respect to the Collateral, whether established
hereby or by other Senior Notes Documents, or by any other agreements or by law
shall be cumulative and may be executed singularly or concurrently.

      22.  Severability. The provisions of this Agreement are severable, and,
if any clause or provision shall be held invalid and unenforceable in whole or
in part in any jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof, in such jurisdiction, and
shall not in any manner affect such clause or provision in any other
jurisdiction, or any other clause or provision of this Agreement in any
jurisdiction.

      23.  DESIGNATED SENIOR INDEBTEDNESS. THE INDEBTEDNESS EVIDENCED BY THIS
AGREEMENT, THE NOTE PURCHASE AGREEMENT, EACH OF THE SENIOR NOTES, AND EACH OTHER
SENIOR NOTES DOCUMENT IS AND SHALL AT ALL TIMES CONSTITUTE "DESIGNATED SENIOR
INDEBTEDNESS" UNDER THE PROVISIONS OF THAT CERTAIN INDENTURE, DATED AS OF
FEBRUARY 1, 1999, AS AMENDED, AMONG OGLEBAY NORTON COMPANY, THE GUARANTORS NAMED
THEREIN AND NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION, AS TRUSTEE.



                                        7



      24.  Waiver; Amendment. Except as provided in Section 17 above, none of
the terms and conditions of this Agreement may be changed, waived, modified or
varied in any manner whatsoever unless in writing duly signed by Pledgor and the
Collateral Agent (and such other percentage of the Noteholders as may be
required by the Note Purchase Agreement). Notwithstanding the foregoing, this
Agreement shall be amended (solely to the extent of replacing 1818 Mezzanine as
the Collateral Agent) by a written notice delivered to Pledgor by the Collateral
Agent and acknowledged in writing by a successor collateral agent; provided that
such acknowledgement shall have the effect of binding such successor collateral
agent to the terms of this Agreement and such successor Collateral Agent shall
be, in its individual capacity, a Noteholder.)

           (b)   Upon the execution and delivery by Pledgor of a Collateral
Assignment and Security Agreement Supplement, Schedules A, B and C thereto (as
applicable) shall be incorporated into and become a part of and supplement
Schedules A, B and C hereto, and the Collateral Agent may attach such
supplemental schedules to such Schedules A, B and C; and each reference to such
Schedules shall mean and be a reference to such Schedules as supplemented
pursuant to each Collateral Assignment and Security Agreement Supplement.

      25.  Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the respective successors and permitted assigns of the
parties, except that Pledgor may not assign any of its rights or duties
hereunder without the prior written consent of the Collateral Agent. Any
attempted assignment or transfer without the prior written consent of the
Collateral Agent shall be null and void. . Without limiting the generality of
the foregoing, any Noteholder may assign or otherwise transfer any Senior Note
held by it to any other Person as permitted in the Note Purchase Agreement, and
such other Person shall thereupon become vested with all the benefits in respect
thereof granted to the Collateral Agent herein or otherwise.

      26.  Notice. All notices, requests, demands and other communications
provided for hereunder shall be in writing and, if to Pledgor, mailed or
delivered to it, addressed to it at the address specified on the signature page
to this Agreement, if to the Collateral Agent or a Noteholder, mailed or
delivered to it, addressed to the address of the Collateral Agent or such
Noteholder specified on the signature pages of the Credit Agreement. All
notices, statements, requests, demands and other communications provided for
hereunder shall be given by overnight delivery or first class mail with postage
prepaid by registered or certified mail, addressed as aforesaid, or sent by
facsimile with telephonic confirmation of receipt, except that notices pursuant
to any of the provisions hereof shall not be effective until received.

      27.  Governing Law/Jurisdiction. This Agreement shall be construed and
enforced in accordance with, and the rights of the parties shall be governed by,
the laws of the State of New York, without regard to principles of conflicts of
law. Pledgor hereby consents to the personal jurisdiction of the state and
federal courts of the State of New York in connection with any controversy
related to this Agreement, waives any argument that venue in such forums is not
convenient and agrees that any litigation initiated by Pledgor against the
Collateral Agent or any Noteholder shall be venued in the State or Federal
District Courts of New York.

      28.  Jury Trial Waiver. Pledgor, the Collateral Agent and the Noteholders,
to the extent permitted by law, each waive any right to have a jury participate
in resolving any dispute,



                                        8




whether sounding in contract, tort, or otherwise, among the Collateral Agent,
the Noteholders and Pledgor, or any of them, arising out of, in connection with,
related to, or incidental to the relationship established between them in
connection with this Agreement or any note or other agreement, instrument or
document executed or delivered in connection therewith or the transactions
related thereto.

         29. Obligations Absolute. The obligations of Pledgor hereunder shall
remain in full force and effect without regard to, and shall not be impaired by,
(a) any bankruptcy, insolvency, reorganization, arrangement, readjustment,
composition, liquidation or the like of Oglebay, Pledgor or any Guarantor; (b)
any exercise or non-exercise, or any waiver of, any right, remedy, power or
privilege under or in respect of this Agreement or any other Senior Notes
Document; or (c) any amendment to or modification of any Senior Notes Document
or any security for any of the Debt whether or not Pledgor shall have notice or
knowledge of any of the foregoing.

         30. Lien Subordination

The liens and security interest granted hereunder, and the rights and remedies
of the Collateral Agent hereunder are subject to the terms of the Intercreditor
Agreement (as such term is defined in the Note Purchase Agreement). Without
limiting, and in furtherance of the foregoing, the Collateral Agent shall not
exercise its rights under Sections 4 and 8(b) hereof so long as the
Intercreditor Agreement is in effect, except as expressly permitted thereby or
otherwise expressly permitted in writing by Key Bank National Association, as
Agent for the Banks under the Intercreditor Agreement. In the event of any
conflict between the terms and provisions of this Agreement and the
Intercreditor Agreement, the terms and provisions of the Intercreditor Agreement
shall govern and control.

         IN WITNESS WHEREOF, each of the Pledgor and the Collateral Agent has
caused this Agreement to be duly executed and delivered by its officer thereunto
duly authorized as of the date first above written.

undersigned, in her capacity as the Chief Financial Officer of the Company,
hereby certifies solely in such capacity and not individually, on behalf of the
Company and each of the Guarantors as follows:

(A)  (1)  The representations and warranties made by or on behalf of the Company
          and each its Subsidiaries in the Agreement, the Security Documents to
          which it is a party and the other Senior Notes Documents to which it
          is a party are true and correct in all material respects on and as of
          the date hereof, with the same effect as if made at and as of the date
          hereof; except to the extent such representations and warranties are
          specifically made as of a particular date or as of the date of the
          applicable Senior Notes Document (in which case such representations
          and warranties are true and correct as of such date);

     (2)  since the Reference Balance Sheet Date, there has occurred no
          materially adverse change in the financial condition or business of
          the Company and its Subsidiaries as shown on or reflected in the
          consolidated balance sheet of the Company as at [________], or the
          consolidated statements of income and cash flows for the period then
          ended, other than changes in the ordinary course of business that have
          not had a Material Adverse Effect. Since the Reference Balance Sheet
          Date, the Company has not made any Distributions, except in accordance
          with the terms of the Agreement;

     (3)  there has been no change (i) in the Organizational Documents of the

          condition which the undersigned reasonably anticipates to give rise to
          a Default thereunder, other than as set forth on Schedule 2 attached
          hereto.

(B)  Attached hereto as Schedule 3 are calculations demonstrating that, based
     upon the financial statements of the Company and its Subsidiaries attached

[Address]

Attn:

Ladies and Gentlemen:

In connection with your proposed purchase (the "Proposed Purchase") of Senior
Notes due 2008 issued by Oglebay Norton Company ("Oglebay") pursuant to the
Senior Secured Note Purchase Agreement, dated as of October __, 2002 (as
amended, supplemented and otherwise modified from time to time, the "Note
Purchase Agreement"), among Oglebay, the Guarantors named therein and the
initial Purchasers named therein, you have received and will receive information
concerning Oglebay and its subsidiaries (collectively, the "Company"). It is a
condition to your receipt of such information that you execute and deliver this
confidentiality agreement to Oglebay. Capitalized terms used herein and not
defined herein are used herein as defined in the Note Purchase Agreement.

You agree that you and any of your representatives (it being understood that
they shall be informed by you of the confidential nature of such information and
that they are bound by the terms of this confidentiality agreement) shall hold
in strict confidence (except as otherwise required by law) any confidential or
proprietary information obtained from the Company (or any Noteholder) (such
information, "Company Confidential Information"). Information disclosed to or
generally known in the industry or obtained or developed by you or your
representatives based on information received from Persons who had a right to
disclose the same to you or such representatives shall not be (and shall not be
deemed to be) confidential or proprietary information or Company Confidential
Information. You agree that you will use Company Confidential Information solely
for the purposes contemplated by the Note Purchase Agreement.

You agree to hold all Company Confidential Information obtained by you in
contemplation of the Proposed Purchase or otherwise pursuant to the requirements
of the Note Purchase Agreement, a copy of the relevant provision of which is
attached hereto as Annex A; provided, however, that you may disclose such
Company Confidential Information (a) to your examiners, affiliates, outside
auditors, counsel and other professional advisors, (b) to any other Noteholder
or to any prospective holder of Senior Notes that has executed a confidentiality
agreement substantially similar to this agreement, and (c) as required or
requested by any governmental authority or representative thereof or pursuant to
legal process; provided, further that unless specifically prohibited by
applicable law or court order, you will use your best efforts prior to
disclosure thereof, to notify Oglebay of the applicable request, (A) by a
governmental authority



or representative thereof (other than any such request in connection with an
examination of your financial condition by such governmental authority) or (B)
pursuant to legal process, for disclosure of such Company Confidential
Information as far in advance of its disclosure as is practicable and, upon
Oglebay's request and at its expense, use your best efforts to obtain assurances
that confidential treatment will be accorded such information.

Except as may be required by applicable law, you hereby agree that you shall not
issue a publicity release or announcement or otherwise make any public
disclosure concerning the Note Purchase Agreement, the transactions contemplated
thereby or the Proposed Purchase, without prior approval by the Noteholders and
Oglebay. If any announcement is required by law to be made by you, prior to
making such announcement you shall deliver a draft of such announcement to the
Noteholders and Oglebay and shall give the Noteholders and Oglebay an
opportunity to comment thereon.

You understand that wrongful use of material, non-public information in the
purchase or sale of securities constitutes a violation of the federal securities
laws.

Upon your receipt of the written request of Oglebay, you agree to redeliver to
Oglebay or destroy promptly the Company Confidential Information delivered to
you by the Company of any Noteholder. You further agree to use commercially
reasonable efforts to destroy all written, electronically-stored and
magnetically-stored memoranda, notes, extractions, abstracts, compilations and
other records prepared by you or your representatives based on the Company
Confidential Information in accordance with your customary procedures for
destroying confidential information. Notwithstanding the foregoing, if the
Proposed Purchase is consummated, in no event shall you be obligated to return
any materials furnished by the Company other than those instruments in your
possession evidencing Senior Notes Obligations once the Senior Notes Obligations
(including the Guaranteed Obligations) have been paid in full in cash and the
Note Purchase Agreement has been terminated in accordance with its terms.

This confidentiality agreement shall be amended automatically without any
further action on the part of any party hereto or otherwise upon your delivery
of an effective joinder agreement in the form of Exhibit A to the Note Purchase
Agreement, whereupon your obligations with respect to all Company Confidential
Information other than Company Confidential Information provided to you under
Section 6.14 of the Note Purchase Agreement (including, without limitation, any
such Company Confidential Information received by the Representative and then
provided to you by the Representative) shall be governed by the terms of the
Note Purchase Agreement. For the avoidance of doubt any Company Confidential
Information that the Company or any of its Subsidiaries is required to provide
(or cause to be provided or made available) to the Noteholders (or the
Collateral Agent as such term is defined in the Security Documents referenced in
the Note Purchase Agreement) under any provision of the Note Purchase Agreement
other than Section 6.14 thereof shall be deemed to be provided under such other
provision of the Note Purchase Agreement (and not Section 6.14 of the Note
Purchase Agreement) for all purposes hereunder.



This letter agreement shall be governed by and construed in accordance with the
laws of the State of New York.

If you are in agreement with the foregoing, please so indicate by signing and
returning one copy of this letter agreement to Oglebay (Attention: Rochelle F.
Walk, Vice President, General Counsel and Secretary).

                                          Very truly yours,

                                          OGLEBAY NORTON COMPANY
