elapsed in a month/30) x (applicable interest rate/12) x outstanding principal
balance on a Note.

Purchasers the unpaid balance of the Notes in full, together with all the
accrued and unpaid interest, fees and other amounts due hereunder on July 31,

Notes in whole or in part in multiples of $100,000, or such lesser amount as is
then outstanding, plus the unpaid accrued interest, if any, on the principal
amount so prepaid, to the date set for prepayment; provided, however, that no

Note has been paid in full. All such prepayments shall be applied by Purchasers
to the outstanding principal after application of such prepayment to any accrued
interest.

      3.4 Notice of Optional Prepayment. If Borrower shall elect to prepay any
Notes pursuant to Section 3.3 hereof, Borrower shall give notice of such

Note for principal and interest to Purchasers by the method and at the address
specified for such purpose in Annex A, or by such other method or at such other
address as Purchasers shall have from time to time specified to Borrower in
writing for such purpose, without the presentation or surrender of such Note or
the making of any notation thereon, except that upon written request of Borrower
made concurrently with or reasonably promptly after payment or prepayment in
full of any Note, each holder of such Note shall surrender their respective Note
for cancellation, reasonably promptly after such request, to Borrower at its
principal executive office.

      3.7 Taxes.

            (a) Any and all payments by Borrower hereunder or under the other
Purchase Documents that are made to or for the benefit of Purchasers shall be
made free and clear of and without deduction for any and all present or future


                                       13
<PAGE>

taxes, levies, imposts, deductions, charges or withholdings and penalties,
interests and all other liabilities with respect thereto (collectively,
"Taxes"), excluding taxes imposed on Purchasers' net income or capital and
franchise taxes imposed on any of them by the jurisdiction under the laws of
which any of them is organized or conducts business or any political subdivision
thereof (all such nonexcluded Taxes being hereinafter referred to as "Covered
Taxes"). Subject to the provisions of Section 3.7(b) hereof, Borrower shall be
required by law to deduct any Covered Taxes from or in respect of any sum
payable hereunder or under any Notes or other Purchase Documents to Purchasers
the sum payable shall be increased as may be necessary so that after making all
required deductions of Covered Taxes (including deductions of Covered Taxes
applicable to additional sums payable under this paragraph), each Purchaser
receives an amount equal to the sum it would have received had no such
deductions been made. Borrower shall make such deductions and Borrower shall pay
the full amount so deducted to the relevant taxation authority or other
authority in accordance with applicable Law. In addition, Borrower agrees to pay
any present or future stamp, documentary, excise, privilege, intangible or
similar levies that arise at any time or from time to time from any payment made
under any and all Purchase Documents or from the execution or delivery by
Borrower or from the filing or recording or maintenance of, or otherwise with
respect to, the exercise by Purchasers of their respective rights under any and
all Purchase Documents (collectively, "Other Taxes"). Subject to the provisions
of Section 3.7(b) hereof, Borrower will indemnify Purchasers for the full amount
of Covered Taxes imposed on or with respect to amounts payable hereunder and
Other Taxes, and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto. Payment of this indemnification shall
be made within thirty (30) days from the date Purchasers provide Borrower with a
certificate certifying and setting forth in reasonable detail the calculation of
the amount and type of such Taxes requiring indemnification. Any such
certificates submitted by Purchasers in good faith to Borrower shall, absent
manifest error, be final, conclusive and binding on all parties. The obligation
of Borrower under this Section 3.7 shall survive the payment of the Notes and
the termination of this Agreement. Within thirty (30) days after Borrower having
received a receipt for payment of Covered Taxes and/or Other Taxes, Borrower
shall furnish to Purchasers the original or certified copy of a receipt
evidencing payment thereof.

            (b) Each Purchaser that (i) is organized under the laws of a
jurisdiction other than the United States of America and (ii) is a party hereto
on the Closing Date (each such Purchaser, a "Foreign Purchaser") shall execute
and deliver to Borrower and Purchasers one or more (as Borrower or Purchasers
may reasonably request) IRS Form W-8ECI, W-8BEN, W-8IMY (as applicable) or other
applicable form, certificate or document prescribed by the IRS certifying as to
such Foreign Purchaser's entitlement to a complete exemption from withholding or
deduction of Taxes. Borrower shall not be required to pay additional amounts to
any Purchaser pursuant to this Section 3.7 to the extent that the obligation to
pay such additional amounts would not have arisen but for the failure of such
Foreign Purchaser to comply with this Section 3.7.

      3.8 Maximum Lawful Rate. The Purchase Documents are hereby limited by this
Section 3.8. In no event, whether by reason of acceleration of the maturity of
the amounts due hereunder or otherwise, shall interest and fees contracted for,
charged, received, paid or agreed to be paid to Purchasers exceed the maximum
amount permissible under such applicable Law. If, from any circumstance
whatsoever, interest and fees would otherwise be payable to Purchasers in excess
of the maximum amount permissible under applicable Law, the interest and fees


                                       14
<PAGE>

shall be reduced to the maximum amount permitted under such applicable Law. If
from any circumstance whatsoever, Purchasers shall have received anything of
value deemed interest by applicable Law in excess of the maximum lawful amount
permitted under applicable Law, an amount equal to any such excess shall be
applied to the reduction of the principal amount of the Notes, in such manner as
may be determined by Purchasers, and not to the payment of fees or interest, or
if such excess exceeds the unpaid balance of the principal amount of the Notes,
such excess shall be refunded to Borrower.

      3.9 Certain Waivers. Borrower unconditionally waives (i) any rights to
presentment, demand, protest or (except as expressly required hereby) notice of
any kind, and (ii) any rights of recission, setoff, counterclaim or defense to
payment under the Notes or otherwise that Borrower may have or claim against any
Purchaser.

                   REPRESENTATIONS AND WARRANTIES OF BORROWER

      5.1 Representations and Warranties of Borrower. As a material inducement
to Purchasers to enter into this Agreement and purchase the Notes, Borrower
hereby represents and warrants to Purchasers as follows:

            (a) Organization and Power. Borrower is a Michigan corporation duly
organized, validly existing and in good standing under the laws of its state of
formation. Borrower has all requisite corporate or other organizational power
and authority and all material licenses, permits, approvals and authorizations
necessary to own and operate its properties, to carry on its businesses as now
conducted and presently proposed to be conducted and to carry out the
Transactions, and is qualified to do business in the jurisdictions listed on the
"Organization Schedule" attached hereto as Schedule 5.1(a), which includes every
jurisdiction where the failure to so qualify would have a Material Adverse
Effect. Borrower has its principal place of business as set forth on the
"Organization Schedule". The copies of the Charter Documents and By-Laws of
Borrower that have been furnished to Purchasers reflect all amendments made
thereto at any time prior to the date of this Agreement and are correct and
complete in all respects.

            (b) Principal Business. Borrower is primarily engaged in the
ownership and charter of the Vessels (the "Business").

            (c) Financial Statements. The pro forma balance sheet of Borrower as

and accurately presents, in all material respects, the financial position of
Borrower as of such date, adjusted to give effect (as if such events had
occurred on such date) to (1) the transactions contemplated by the Purchase
Documents including, without limitation the sale of the Notes, (2) the
transactions contemplated by the Senior Credit Agreement, including without
limitation, the Senior Financing, (3) the application of the proceeds therefrom
as contemplated by the Purchase Documents and (4) the payment of all legal,
accounting and other fees related thereto to the extent known at the time of the


                                       17
<PAGE>

preparation of such balance sheet. As of the date of such balance sheet,
Borrower (after giving effect to the pro forma adjustments) has no any material
liabilities of a type required to be recorded on a balance sheet in accordance
with GAAP which are not recorded on such pro forma balance sheet.

            (d) Capitalization and Related Matters.

the number of visits or inspections permitted below, Borrower and its
Subsidiaries shall be responsible for the cost of only one (1) such visit or
inspection per Purchaser per Fiscal Year so long as no Event of Default exists)
representatives of any Purchaser to visit and inspect any of their respective
properties, to examine and make abstracts or copies from any of their respective
books and records and to discuss their respective affairs, finances and accounts
with their respective officers, employees and independent public accountants as
often as may reasonably be desired; provided, however that Purchasers shall
agree to keep all information that is subject to a confidentiality agreement

established on any property as a result thereof, such demand to be made, if at
all, upon Purchasers' reasonable business determination that the failure to

Borrower to the holders thereof hereunder and thereunder shall be immediately
due and payable, without presentment, demand, protest or (except as expressly
required hereby) notice of any kind, all of which are hereby expressly waived.

            (b) Other Defaults. If any Event of Default shall occur other than
as specified in Section 7.1(g) or 7.1(h) hereof, Purchasers may, upon election
of the holders of not less than 51% of the Commitments, at their option, by
written notice to Borrower, declare the entire unpaid balance of the Notes,
interest accrued thereon and all other liabilities of Borrower hereunder and
thereunder to be forthwith due and payable, and the same shall thereupon become
immediately due and payable, without presentment, demand, protest or (except as
expressly required hereby) notice of any kind, all of which are hereby expressly
waived.

            (c) Penalty Interest. Following the occurrence and during the
continuance of any Event of Default, the holders of the Notes shall be entitled
to receive, to the extent permitted by applicable law, interest on the
outstanding principal of, and premium and overdue interest, if any, on, the
Notes at a rate per annum equal to the interest rate thereon (determined as
provided in Section 3.1) plus the greater of (i) two hundred (200) basis points,
or (ii) the amount in excess of the rate otherwise applicable to the obligations
under Senior Financing Documents upon the occurrence of an Event of Default (as
defined therein) (the "Default Rate").

            (d) Board Rights. In the event the Senior Subordinated Notes are not
repaid in full on the Maturity Date, Oglebay shall be entitled to have an
observer on its behalf attend all meetings of the board of directors of
Borrower.

            (e) Purchase of Senior Debt. In the event either Parent or Rand or
any Affiliate of either thereof acquires the Senior Debt from Senior Lender, the
Senior Subordinated Notes held by Oglebay shall become pari passu in right of
payment and security with the Senior Debt and Borrower and Rand or Parent or
such Affiliate, as applicable, shall execute any and all security documents and
intercreditor and other agreements to secure the Senior Subordinated Notes on a
pari passu basis with the Senior Debt in all property of Borrower or other
Persons securing the Senior Debt.

failure in exercising any right, power or remedy hereunder shall affect or
operate as a waiver thereof; nor shall any single or partial exercise thereof or
any abandonment or discontinuance of steps to enforce such a right, power or
remedy preclude any further exercise thereof or of any other right, power or
remedy. The rights and remedies hereunder are cumulative and not exclusive of

Purchasers under this Section 8.8 shall supersede and replace the obligations of
Purchasers under any confidentiality agreement in respect of this financing
executed and delivered by any Purchaser prior to the date hereof.
