of any such counsel, accountants or other skilled persons. In the event that the Depositary shall be uncertain or believe there is some ambiguity as to its duties or rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held hereunder until it shall be given a direction in writing by the Escrow Agent or the Pass Through Trustee which eliminates such ambiguity or uncertainty to the satisfaction of Depositary or by a final and non-appealable order or judgment of a court of competent jurisdiction. Anything in this Agreement to the contrary notwithstanding, in no event shall the Depositary be liable for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Depositary has been advised of the likelihood of such loss or damage and regardless of the form of action. In the event of any conflict or inconsistency between any provision in this Agreement and a provision in any other document with respect to the subject matter of this Agreement, the provisions of this Agreement shall control.

(d) If any portion of the Deposit is at any time attached, garnished or levied upon under any court order, or enjoined or stayed by any court order, or in case of any order, judgment or decree shall be made or entered by any court affecting the Deposits or any part thereof, then and in any such event, the Depositary is authorized to rely upon and comply with any such order, writ, judgment or decree which it is advised in writing by external legal counsel of national reputation is binding upon it without the need for appeal or other action; and if the Depositary complies with such order, writ, judgment or decree, it shall not be liable to the Escrow Agent or any Receiptholder commencing action pursuant to Section 16 even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated so long as such order, writ, judgment or decree was not made, issued or entered for any reason that a final adjudication of a court of competent jurisdiction determines was based on the Depositary’s gross negligence or willful misconduct.

(e) Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the Depositary to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Escrow Agent acknowledges that Section 326 of the USA PATRIOT Act and the Depositary’s identity verification procedures require the Depositary to obtain information which may be used to confirm the Escrow Agent’s identity including without limitation name, address and organizational documents (“identifying information”). The Escrow Agent agrees to provide the Depositary with and consent to the Depositary obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Depositary.

(f) No party to this Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, unavailability of wire services or other causes reasonably beyond its control. If any provision of this Agreement is determined to be prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction.
