own similar property.

(b) This Section 8 of this Agreement expressly sets forth all the duties of the
escrow agent with respect to any and all matters pertinent hereto. No implied
duties or obligations shall be read into this Agreement against the escrow
agent. The escrow agent shall not be bound by the provisions of any agreement
among the other parties hereto except this Section 8 of this Agreement.

(c) The escrow agent shall not be liable, except for its own gross negligence or

certification, demand, notice, instrument or other writing delivered to it
hereunder without being required to determine the authenticity or the
correctness of any fact stated therein or the propriety or validity of the
service thereof. The escrow agent may act in reliance upon any instrument or
signature believed by it to be genuine and may assume that any person purporting
to give receipt or advice or make any statement or execute any document in
connection with the provisions hereof has been duly authorized to do so.

(e) The escrow agent may act pursuant to the advice of counsel with respect to
any matter relating to this Agreement and shall not be liable for any action
taken or omitted in accordance with such advice.

(f) The escrow agent does not have any interest in the Escrowed Property
deposited hereunder but is serving as escrow holder only and having only
possession thereof. The other parties shall, on a joint and several basis, pay
or reimburse the escrow agent upon request for any and all expenses, if any,
incurred by the escrow agent in connection with this Agreement and transfer
taxes or other taxes relating to the Escrowed Property incurred in connection

Property to any successor escrow agent jointly designated by the other parties
hereto in writing, or to any court of competent jurisdiction, whereupon the
escrow agent shall be discharged of and from any and all further obligations
arising in connection with this Agreement. The resignation of the escrow agent
will take effect on the earlier of (a) the appointment of a successor (including
a court of competent jurisdiction) or (b) the day which is 30 days after the
date of delivery of its written notice of resignation to the other parties
hereto. If at that time the escrow agent has not received a designation of a
successor escrow agent, the escrow agent's sole responsibility after that time
shall be to safekeep the Escrowed Property until receipt of a designation of
successor escrow agent or a joint written disposition instruction by the other
parties hereto or a final order of a court of competent jurisdiction.

(i) In the event of any disagreement between the other parties hereto resulting
in adverse claims or demands being made in connection with the Escrowed
Property, or in the event that the escrow agent in good faith is in doubt as to
what action it should take hereunder, the escrow agent shall be entitled to
retain the Escrowed Property until the escrow agent shall have received (i) a
final non-appealable order of a court of competent jurisdiction directing
delivery of the Escrowed Property or (ii) a written agreement executed by the
other parties hereto directing delivery of the Escrowed Property, in which event
the escrow agent shall disburse the Escrowed Property in accordance with such
order or agreement. Any court order shall be accompanied by a legal opinion by
counsel for the presenting party satisfactory to the escrow agent to the effect
that said opinion is final and non-appealable.

(j) Notwithstanding anything to the contrary contained herein, the escrow
agent's duties and obligations hereunder shall terminate upon the release and
distribution of the Escrowed Property in accordance with the terms of this
Agreement.

(k) Each of the Company and the Purchaser understands and agrees that,
notwithstanding its duties as escrow agent hereunder, the escrow agent is the
attorney for the Company, and, accordingly, neither any services as escrow agent
hereunder nor any provisions hereof, either express or implied, shall restrict
or inhibit the escrow agent in any way from representing the Company or its
affiliates in any action, dispute, controversy, arbitration, suit or negotiation
arising under this Agreement or under any other agreement or in any manner or
context whatsoever, whether or not directly or indirectly involving the Company
or its affiliates. Notwithstanding anything to the contrary contained herein, if
at any time a law firm representing either Company or Purchasers serves or is
serving as escrow agent, then with respect to such law firm's capacity as escrow
agent, such counsel shall not for these purposes serve as the agent for either
of the parties, but shall be a fiduciary of both parties.
