made applicable to the Collateral, this Agreement and/or the Obligations, as

         (b) The Secured Parties will give Debtor reasonable notice of 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. Expenses of
retaking, holding, preparing for sale, selling, leasing or the like shall
include Secured Parties' reasonable attorney's fees and legal expenses. The
Debtor acknowledges and agrees that any private sale of the Collateral may
result in prices and other terms less favorable than if such sale were a public
sale and, notwithstanding such circumstances, agrees, to the extent permitted by
applicable law, that any such private sale shall be deemed to have been made in
a commercially reasonable manner. To the extent permitted by the laws of the
State of West Virginia, in the event of a sale, by foreclosure, power of sale,
or otherwise, of less than all of the Collateral, this Agreement shall continue
as a lien and security interest on the remaining portion of the Collateral
unimpaired and without loss of priority.

         Section 8.2 Application of Proceeds. Subject to the rights of the First
Secured Party under the First Lien Documents, after deducting all reasonable
costs and expenses of every kind incurred by the Secured Parties or incidental
to the care, safekeeping or otherwise of any and all of the Collateral, the
purchase money, proceeds and avails of any disposition of the Collateral, or any
part thereof, or any other sums collected by the Secured Parties pursuant to
this Agreement or the Deeds of Trust, may be applied by the Secured Parties to
the payment of the Obligations in accordance with the Second Lien Intercreditor
Agreement to the extent then in effect. Only after credit against the
Obligations and after the payment by the Secured Parties of any other amount
required by any provision of law, including, without limitation, the UCC, need
the Secured Parties' account for the surplus, if any, to the Debtor.

         Section 8.3 Waiver of Rights Under UCC; Deficiency. The Debtor shall be
liable for the deficiency if the proceeds of any sale or other disposition of
the Collateral are insufficient to pay all amounts to which the Secured Parties
are entitled and the


                                       10
<PAGE>

reasonable costs, fees and expenses of any attorney employed by the Secured
Parties to collect such deficiency.

         Section 8.4 Actions and Proceedings. After the occurrence and during
the continuance of an Event of Default, the Secured Parties have the right to
appear in and defend any action or proceeding brought with respect to the
Collateral and to bring any action or proceeding, in the name and on behalf of
Debtor, which Secured Parties, in their discretion, decide should be brought to
protect their interest in the Collateral.

         Section 8.5 Other Rights, Etc. 1. No delay or failure of the Secured
Parties in the exercise of any right or remedy hereunder shall operate as a
waiver thereof, and no single or partial exercise of any right or remedy
hereunder shall preclude other or further exercise thereof or the exercise of
any other right or remedy. No action or forbearance by the Secured Parties
contrary to the provisions of this Agreement shall be construed to constitute a
waiver of any of the express provisions hereof. The Secured Parties may
specifically waive any of their rights under this Agreement without invalidating
the entire Agreement. Nothing herein contained, nor anything done or omitted to
be done by the Secured Parties pursuant hereto, shall be deemed a waiver by the
Secured Parties of any of their rights or remedies hereunder or under any of the
Debt Instruments or under applicable law.

         (b) The rights of the Secured Parties under this Agreement shall be
separate, distinct and cumulative and none shall be given effect to the
exclusion of the others. No act of the Secured Parties shall be construed as an
election to proceed under any one provision herein to the exclusion of any other
provision. The Secured Parties shall not be limited exclusively to the rights
and remedies herein stated but shall be entitled to every right and remedy now
or hereafter afforded at law or in equity.

         Section 8.6 Right to Release any Portion of the Collateral. The Secured
Parties, or the Collateral Agent on their behalf to the extent provided in the
Debt Instruments, may release any portion of the Collateral for such
consideration as Secured Parties or Collateral Agent, as applicable, may require
and in accordance with the terms of the Debt Instruments without, as to the
remainder of the Collateral, in any way impairing or affecting the lien or
priority of this Agreement, or improving the position of any subordinate
lienholder with respect thereto, except to the extent that the obligations
hereunder shall have been reduced by the actual monetary consideration, if any,
received by Secured Parties for such release, and may accept by assignment,
pledge or otherwise any other property in place thereof as Secured Parties may
require without being accountable for so doing to any other lienholder. This
Agreement shall continue as a lien and security interest in the remaining
portion of the Collateral.

         Section 8.7 Right of Entry. Each of the Secured Parties and its agents
shall have the right upon prior written notice to enter and inspect the
Collateral at all reasonable times upon reasonable advance notice to Debtor.

         Section 8.8 Exercise of Remedies by Secured Parties. Notwithstanding
anything to the contrary contained herein, the ability of a Secured Party to
accelerate the


                                       11
<PAGE>

Debtor's Obligations hereunder and/or exercise any of the remedies provided for
in this Article 8, shall be subject to and governed by any limitations or
restrictions on such rights as may be set forth in the Notes Indenture (if such
Secured Party is the Notes Secured Party) or the Bond Loan Agreement (if such
Secured Party is the Bond Secured Party), and in either case, by any limitations
or restrictions on such rights as may be set forth in the First Lien
Intercreditor Agreement to the extent then in effect (provided, however, for
purposes of the foregoing and in the interest of clarity, Debtor is not intended
to be a third party beneficiary of the limitations and restrictions on the
Secured Parties' rights to accelerate and exercise remedies contained in the
First Lien Intercreditor Agreement).
