WHEREAS,
each Grantor wishes to grant a limited security interest in favor of the Administrative Agent, for the benefit of the Secured Parties as herein provided.

NOW,
THEREFORE, in consideration of the promises 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.All capitalized terms used herein (including in the Preamble and Recitals hereto) without
definitions shall have the respective meanings provided therefor in the Credit Agreement. The term "State," as used herein, means the State of New York. All terms defined in the Uniform Commercial
Code of the State and used herein shall have the same definitions herein as specified therein. However, if a term is defined in Article 9 of the Uniform Commercial Code of the State differently
than in another Article of the Uniform Commercial Code of the State, the term has the meaning specified in Article 9.

2.Grant of Security Interest.Subject to the terms and conditions set forth in the Order and the other terms
and conditions set forth in this Agreement, including in Sections 8 and 9 hereof, each Grantor hereby grants to the Administrative Agent, for the benefit of the Secured Parties, to secure the payment
and performance in full of all of the allowed Obligations of Coudersport and Bucktail under the Credit Agreement (and only under the Credit Agreement), a security interest in all of the properties,
assets and rights of such Grantor, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof, including, without limitation, all personal and fixture
property of every kind and nature, including all goods (including inventory, equipment and

---



any
accessions thereto), instruments (including promissory notes), documents, accounts, chattel paper (whether tangible or electronic), deposit accounts, letter-of-credit
rights (whether or not the letter of credit is evidenced by a writing), commercial tort claims, supporting obligations, any other contract rights or rights to the payment of money, insurance claims
and proceeds, and all general intangibles (including all payment intangibles), in each case, to the extent (and only to the extent) that such properties, assets and rights are wholly-owned by such
Grantor or another Grantor that is a member of the Borrower Group (as defined in the DIP Facility (as defined in the Order)) designated as the "Olympus" Borrower Group under the DIP Facility (all of
the same being hereinafter called the "Collateral");provided,however, that Collateral shall not
include (a) any franchises, licenses or equivalent rights (collectively, "Franchises") as and to the extent that the granting of a security interest in any such Franchise would result in the
forfeiture, termination or loss of such Franchise or the breach of any of the terms or conditions of any agreement governing any such Franchise, it being agreed that the exclusion provided for in this
clause (a) shall not apply to the proceeds realized upon any sale or other disposition of such Franchise, with any such proceeds constituting Collateral hereunder, (b) the equity
interests held by any Grantor, whether as of the date hereof or hereafter acquired, in any subsidiary of any Grantor or (c) any assets, properties or rights of any Grantor to the extent that
any such asset, property or right was subject, as of June 25, 2002, to a valid, perfected and non-avoidable lien.

3.Perfection and Other Actions.Pursuant to the terms of the Order, the security interests granted under
Section 2 hereof shall be automatically perfected effective as of the Forfeiture Date (as defined in the Order). Each Grantor further agrees to execute such other documentation as the
Administrative Agent may reasonably request to evidence and perfect the security interests granted under Section 2 hereof, which documents shall be in form reasonably satisfactory to the
Co-Lead Arrangers (as defined in the Order) and shall otherwise be subject to the terms and conditions set forth herein and in the Order.

4.Administrative Agent's Obligations and Duties.Anything herein to the contrary notwithstanding, each Grantor
shall remain obligated and liable under each contract or agreement comprised in the Collateral to be observed or performed by such Grantor thereunder. The Administrative Agent shall not have any
obligation or liability under any such contract or agreement by reason of or arising out of this Agreement or the receipt by the Administrative Agent of any payment relating to any of the Collateral,
nor shall the Administrative Agent be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any such contract or agreement, to make inquiry as to the nature or
sufficiency of any payment received by the Administrative Agent in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, to present
or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to the Administrative Agent or to which the Administrative Agent
may be entitled at any time or times.

5.No Waiver by Administrative Agent, etc.The Administrative Agent shall not be deemed to have waived any of
its rights or remedies in respect of the Obligations or the Collateral unless such waiver shall be in writing and signed by the Administrative Agent. No delay or omission on the part of the
Administrative Agent in exercising any right or remedy shall operate as a waiver of such right or remedy or any other right or remedy. A waiver on any one occasion shall not be construed as a bar to
or waiver of any right or remedy on any future occasion. Subject to the terms and conditions set forth herein and the terms and conditions set forth in the Order and in any other order entered by the
Bankruptcy Court (whether as of the date hereof or hereafter) in the bankruptcy cases of the Grantors, all rights and remedies of the Administrative Agent with respect to the Obligations or the
Collateral, whether evidenced hereby or by any other instrument or papers, shall be cumulative and may be exercised singularly, alternatively, successively or concurrently at such time or at such
times as the Administrative Agent deems expedient.

6.Suretyship Waivers by Grantor.Each Grantor waives demand, notice, protest, notice of acceptance of this
Agreement, notice of loans made, credit extended, Collateral received or delivered or other action taken in reliance hereon and all other demands and notices of any description. With respect to both
the Obligations and the Collateral, each Grantor assents to any extension or postponement of the time of payment or any other indulgence, to any substitution, exchange or release of or failure to
perfect any security interest in any Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement,
compromising or adjusting of any thereof, all in such manner and at such time or times as the Administrative Agent may deem advisable.

AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE AND THE BANKRUPTCY CODE. Each Grantor and the Administrative Agent (on
behalf of all Secured Parties) agrees that any action or claim arising out of, or any dispute in connection with, this Agreement, any rights, remedies, obligations, or duties hereunder, or the

the event that following the date hereof, the Administrative Agent or any other Agent or Lender under the Credit Agreement is authorized by the Bankruptcy Court to exercise any rights or remedies
against Coudersport and/or Bucktail and/or the equity interests representing ownership of Coudersport and/or Bucktail, then effective on the effective date of any such authorization by the Bankruptcy
Court, and without any further action by any party hereto, this Agreement and any and all security interests granted hereunder or rights conferred hereby shall automatically be deemed to have been
revoked and shall become ineffective.

10.Miscellaneous.The headings of each section of this Agreement are for convenience only and shall not define
or limit the provisions thereof. This Agreement and all rights and obligations hereunder shall be binding upon each Grantor and its respective successors and assigns, and shall inure to the benefit of
the Administrative Agent and its successors and permitted assigns. If any term of this Agreement shall be held to be invalid, illegal or unenforceable, the validity of all other terms hereof shall in
no way be
affected thereby, and this Agreement shall be construed and be enforceable as if such invalid, illegal or unenforceable term had not been included herein.
