The Collateral Agent hereby appoints and authorizes the Depositary Agent to act as depositary agent hereunder with such powers as are expressly delegated to the Depositary Agent by the terms of this Agreement. The Depositary Agent hereby accepts such appointment and each Issuer hereby acknowledges such appointment. The Depositary Agent shall not have any duties or responsibilities except those expressly set forth in this Agreement, or be a trustee or a fiduciary for any Issuer or any Secured Party. Notwithstanding anything to the contrary contained herein, the Depositary Agent shall not be required to take any action which is contrary to this Agreement, the Indenture or the Pledge and Security Agreement or under applicable law or which exposes the Depositary Agent to any liability. The Depositary Agent and its directors, officers, employees and agents shall not be responsible for any action taken or omitted to be taken by it or them in good faith hereunder or in connection herewith, except for its or their own gross negligence or willful misconduct. The Depositary Agent may employ agents and attorneys-in-fact so long as they are selected by it with reasonable care. Except as otherwise provided under this Agreement, the Depositary Agent shall take such action with respect to the Accounts and Account Funds as shall be directed by the Collateral Agent.

6.2 Reliance by Depositary Agent. The Depositary Agent shall be entitled to rely upon any certificate, notice or other document (including any cable, telegram, facsimile or telex) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Depositary Agent. As to any other matters not expressly provided for by this Agreement, the Depositary Agent shall not be required to take any action or exercise any discretion, but shall be required to act or to refrain from acting upon instructions of the Collateral Agent (except that the Depositary Agent shall not be required to take any action which exposes the Depositary Agent to personal liability or which is contrary to this Agreement, the Indenture, the Pledge and Security Agreement or applicable law) and shall in all cases be fully protected in acting, or in refraining from acting, hereunder in accordance with the instructions of the Collateral Agent. The Depositary Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Depositary Agent has received a notice from the Collateral Agent, a Secured Party or an Issuer, referring to this Agreement, describing such Default or Event of Default and indicating that such notice is a notice of default.

The Issuers, jointly and severally, assume all liabilities for, and agree to indemnify, protect, save and keep harmless the Depositary Agent and the Secured Parties and their respective successors, assigns, agents, attorneys and servants from and against, any and all claims, liabilities, obligations, losses, damages, penalties, costs and expenses that may be imposed on, incurred by, or asserted against, at any time, the Depositary Agent or the Secured Parties and in any way relating to or arising out of the execution, delivery and performance of this Agreement, the establishment of the Accounts, the acceptance of deposits, the purchase or sale of Permitted Investments, the retention of cash and Permitted Investments or the proceeds thereof, or as may arise by reason of any act, omission or error of the Depositary Agent made in good faith in the conduct of its duties; except that the Issuers shall not be required to indemnify, protect, save and keep harmless

the Depositary Agent or the Secured Parties or their respective successors, assigns, agents, attorneys or servants against their own gross negligence or willful misconduct. The indemnities contained in this Section 6.3 shall survive the termination of this Agreement or removal or resignation of the Depositary Agent.

6.4 Resignation and Removal.

6.4.1 The Depositary Agent may at any time resign by giving 30 days' written notice to each other party to this Agreement, such resignation to be effective upon the appointment of a successor depositary agent as provided below. The Collateral Agent may remove the Depositary Agent at any time by giving notice to each other party to this Agreement, such removal to be effective upon the appointment of successor depositary agent as provided below.

6.4.2 In the event of any resignation or removal of the Depositary Agent, a successor depositary agent, which shall be a bank or trust company organized under the laws of the United States of America or of the State of New York, having a corporate trust office in New York City and a capital and surplus of not less than $50,000,000, shall be appointed by the Collateral Agent with the consent of the Issuers (such consent shall not be unreasonably withheld). If a successor depositary agent shall not have been appointed and accepted its appointment as depositary agent within 45 days after such notice of resignation of the Depositary Agent or such notice of removal of the Depositary Agent, the Depositary Agent, the Collateral Agent or the Issuers may apply (at the sole cost and expense of the Issuers) to any court of competent jurisdiction to appoint a successor depositary agent to act until such time, if any, as a successor depositary agent shall have accepted its appointment as provided above.

6.4.3 Upon the replacement of the Depositary Agent hereunder, all Account Funds in the Accounts shall be transferred to the successor depositary agent.
