For the avoidance of doubt, to the extent that the value of any Escrow Investment declines, the Company shall not have any obligation to deposit additional funds in the Escrow Account or to ensure that at all times the aggregate amount of the Escrowed Funds equals or exceeds the Special Mandatory Prepayment Price.

Any such Officer’s Certificate may state that the release of the Escrowed Funds is conditioned upon the occurrence or non-occurrence of any event specified therein, in which case such notice may be revoked by the Company if such condition is not satisfied.

(b) If (i) the Escrow Agent has not received an Officer’s Certificate at or prior to 5:00 p.m. (New York City time) on the Outside Date, or (ii) the Escrow Agent has received an Escrow Termination Notice from the Company on or prior to the Outside Date or (iii) the Purchase and Sale Agreement is terminated (notice of which must be given by the Company to the Escrow Agent within three Business Days thereof), then, in each case, the Escrow Agent shall (x) at any time on or prior to the applicable Special Mandatory Prepayment Date liquidate all Escrowed Funds then held by it and (y) at any time on or prior to the applicable Special Mandatory Prepayment Date release (A) an amount of the Escrowed Funds to the Administrative Agent in accordance with the written instructions of the Administrative Agent equal to the Special Mandatory Prepayment Price (which shall be reduced to reflect any prior or substantially contemporaneous payment of any Special Optional Prepayment Amount pursuant to Section 5(c) below) for application pursuant to Section 2.05(b)(iv) of the Credit Agreement (the “Special Mandatory Prepayment”) and (B) any remaining amount of the Escrowed Funds to the Company in accordance with the written instructions of the Company.

(c) If the Escrow Agent has received a Special Optional Prepayment Notice from the Company on or prior to the Outside Date, then the Escrow Agent shall (x) within one Business Day of receipt of such notice liquidate all or a portion of the Escrowed Funds then held by it sufficient to pay the Special Optional Prepayment Amount, as identified in the Special Optional Prepayment Notice, and (y) within one Business Day of such notice release (A) an amount of the Escrowed Funds equal to the Special Optional Prepayment Amount as directed by the Initial Borrower for application pursuant to the final proviso of Section 2.05(a)(i) of the Credit Agreement and (B) any remaining amount of the Escrowed Funds shall remain in the Escrow Account for further distribution in accordance with Sections 5(a) or 5(b) of this Agreement.

(d) Notwithstanding anything in this Agreement to the contrary, the Escrow Agent shall disburse the Escrowed Funds as directed pursuant to a final judgment (without further right of appeal) of a court of competent jurisdiction; provided, however, that the Escrow Agent shall provide notice thereof to the Company and the Administrative Agent prior to such disbursement.

Under no circumstances will the Escrow Agent be deemed to be a fiduciary to any party hereto or any other person under this Agreement. The Escrow Agent shall not be subject to, nor required to comply with, any other agreement between or among any or all of the other parties hereto or to which any of them is a party, even though reference thereto may be made herein or such agreement has been given to the Escrow Agent, or to comply with any direction or instruction (other than those contained herein or delivered in accordance with this Agreement) from any such party or any entity acting on its behalf. The Escrow Agent shall not be required to, and shall not, except as otherwise specified in this Agreement, expend or risk any of its own funds or otherwise incur any financial liability in the performance of any of its duties or the exercise of its rights hereunder.

(b) If at any time the Escrow Agent is served with any judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process which in any way affects the Escrowed Funds (including, but not limited to, orders of attachment or garnishment or other forms of levies or injunctions or stays relating to the transfer of the Escrowed Funds), the Escrow Agent is authorized to comply therewith in any manner as it or its legal counsel of its own choosing deems appropriate and if the Escrow Agent complies with any such judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process, the Escrow Agent shall not be liable to the Company, the Administrative Agent or the Lenders even though such order, judgment, decree, writ or process may be subsequently modified or vacated or otherwise determined to have been without legal force or effect; provided, however, that the Escrow Agent shall inform the Company and the Administrative Agent promptly and no later than two Business Days thereafter of the receipt of such order, judgment, decree, writ or process and, to the extent permitted under applicable law, will deliver to the Company and the Administrative Agent all relevant documents ancillary to such order, judgment, decree, writ or process so that the Company may seek an appropriate protective order or pursue other legal remedies; provided, further, however, that the Escrow Agent will not comply with such judicial or administrative order, judgment, decree, writ or judicial or administrative process until such time as it is, in the opinion of its counsel, legally compelled to do so.

(c) In no event shall the Escrow Agent be liable (i) for acting in good faith in accordance with or relying in good faith upon any instruction, notice, demand, certificate or document reasonably believed by it to be from the Company or any Person acting on behalf of the Company so long as such action is reasonably believed by it to be taken in accordance with the rights or powers conferred upon it by this Agreement,

9

(ii) for the acts or omissions of its nominees, correspondents, designees, agents, subagents or subcustodians acting in accordance with the terms of this Agreement; provided that such nominees, correspondents, designees, agents, subagents or subcustodians were chosen with due care by the Escrow Agent, or (iii) for an amount in excess of the value of the Escrowed Funds, valued as of the date of deposit, plus all interest, dividends and other distributions and payments thereon.

(d) The Escrow Agent shall not incur any liability to the Company, the Administrative Agent or the Lenders for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the Escrow Agent (including, but not limited to, any act or provision or any present or future law or regulation or governmental authority, any act of God or war or the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility).

(e) The Escrow Agent shall not be responsible in any respect for the form, execution, validity, value or genuineness of documents, or for any description therein, or for the identity, authority or rights of persons executing or delivering or purporting to execute or deliver any such document, security or endorsement. In no event shall the Escrow Agent be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

(f) In the event of any ambiguity or uncertainty hereunder or in any notice, instruction or other communication received by the Escrow Agent hereunder, the Escrow Agent may refrain from taking any action other than releasing the Escrowed Funds in accordance with Section 5 hereof, unless the Escrow Agent receives written instructions, signed by each of the Company and the Administrative Agent, which eliminates such ambiguity or uncertainty.

(g) The Escrow Agent and its directors, officers, employees, attorneys and agents shall be entitled to conclusively rely on any communication, instrument or document reasonably believed by it or them to be genuine and correct and to have been signed or sent by the proper Person or Persons. Any communication, instrument or document required or permitted under this Agreement shall be in writing and shall be given to the address set forth in Section 10.1 (or to such other address as may be substituted therefor by written notification to the other parties hereto). Notices to the Escrow Agent shall be deemed to be given when actually received by the Escrow Agent.

10

(h) In the event of any dispute between, or conflicting claims, demands or instructions by or among, any parties to this Agreement (other than the Escrow Agent) with respect to any Escrowed Funds, the Escrow Agent shall be entitled to refuse to comply with any and all claims, demands or instructions with respect to such Escrowed Funds so long as such dispute or conflict shall continue, and the Escrow Agent shall not be or become liable in any way for such failure or refusal to comply with such conflicting claims, demands or instructions; provided, however, notwithstanding anything to the contrary in the foregoing, the Escrow Agent shall release the Escrowed Funds in accordance with Section 5. The Escrow Agent shall be entitled to refuse to act until either (i) such conflicting or adverse claims or demands shall have been determined by a final order, judgment or decree of a court of competent jurisdiction, which order, judgment or decree is not subject to appeal, or settled by agreement between the conflicting parties as evidenced in a writing satisfactory to the Escrow Agent or (ii) the Escrow Agent shall have received security or an indemnity satisfactory to it sufficient to hold it harmless from and against any and all Losses (as defined herein) which it may incur by reason of so acting. The Escrow Agent may, in addition, elect to commence an interpleader action or seek other judicial relief or orders as it may deem necessary. The costs and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such proceeding shall be paid by, and shall be deemed an obligation of, the Company.

(i) The rights and remedies conferred upon the Escrow Agent and each of the parties hereto shall be cumulative, and the exercise or waiver of any such right or remedy shall not preclude or inhibit the exercise of any additional rights or remedies. The waiver of any right or remedy hereunder shall not preclude the subsequent exercise of such right or remedy.

SECTION 7. Indemnity. The Company shall indemnify, hold harmless and defend the Escrow Agent and its directors, officers, agents and employees, from and against any and all claims, losses, actions, obligations, liabilities, damages, costs and expenses (collectively, “Losses”) directly or indirectly arising out of, relating to or in connection with its acceptance of its appointment hereunder or its performance as Escrow Agent (including but not limited to Losses incurred by the Escrow Agent in connection with its successful defense, in whole or in part, of any claim of bad faith, willful misconduct or gross negligence on its part), except to the extent that such Losses arise from the Escrow Agent’s bad faith, willful misconduct or gross negligence.
