The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through affiliates or agents.

(e) The Escrow Agent may consult with counsel, accountants and other skilled persons to be selected and retained by it.

(f) The Escrow Agent shall not be responsible or liable for any failure or delay in the performance of its obligation under this Escrow Agreement arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; wars; acts of terrorism; civil or military disturbances; sabotage; epidemic; riots; interruptions, loss or malfunctions of utilities, computer (hardware or software) or communications services; accidents; labor disputes; acts of civil or military authority or governmental action; it being understood that the Escrow Agent shall use commercially reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as reasonably practicable under the circumstances.

The Escrow Agent shall also be entitled to payment of any amounts to which the Escrow Agent is entitled under the indemnification provisions contained herein as set forth in Section VII hereof.

The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto.

(c) The Escrow Agent shall not be liable for any action taken by it in good faith and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement, and may consult with counsel of its own choice and shall have full and complete authorization and indemnification, for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel.

(d) The Escrow Agent shall not be liable, directly or indirectly, for any (i) damages, losses or expenses arising out of the services provided hereunder, other than damages, losses or expenses which have been finally adjudicated to have directly resulted from the Escrow Agent’s gross negligence or willful misconduct, or (ii) special, indirect, punitive, or consequential damages or losses of any kind whatsoever (including without limitation lost profits), even if the Escrow Agent has been advised of the possibility of such losses or damages and regardless of the form of action.

(b) The Escrow Parties agree to provide the Escrow Agent with and consent to the Escrow Agent obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Escrow Agent and that any such underlying transaction does not constitute an installment sale requiring any tax reporting or withholding of imputed interest or original issue discount to the IRS or other taxing authority.
