ARTICLE V

PROVISIONS RELATING TO THE ESCROW AGENT




     Section 5.1 The Escrow Agent shall have no duties or responsibilities whatsoever with respect
to the Escrowed Property except as are specifically set forth herein. The Escrow Agent shall
neither be responsible for or under, nor chargeable with knowledge of the terms and conditions of,
any other agreement, instrument or document in connection herewith, including without limitation
the Merger Agreement. The Escrow Agent may conclusively rely upon, and shall be fully protected
from all liability, loss, cost, damage or expense in acting or omitting to act pursuant to any
written notice, instrument, request, consent, certificate, document, letter, opinion, order,
resolution or other writing hereunder that is in a form and manner consistent with the requirements
set forth in this Escrow Agreement without being required to determine the authenticity of such
document, the correctness of any fact stated therein, the propriety of the service thereof or the
capacity, identity or authority of any party purporting to sign or deliver such document. The
Escrow Agent shall have no responsibility for the contents of any such writing contemplated herein
and may rely without any liability upon the contents thereof. Concurrently with the execution of
this Escrow Agreement, the Other Parties shall deliver to the Escrow Agent authorized signers’
forms in the form of Exhibit B-1 and Exhibit B-2 to this Escrow Agreement.


The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and
reasonably believed by it to be authorized hereby or within the rights or powers conferred upon it




4









 







hereunder, nor for action taken or omitted by it in good faith, and in accordance with advice of
counsel (which counsel may be of the Escrow Agent’s own choosing), and shall not be liable for any
mistake of fact or error of judgment or for any acts or omissions of any kind except for its own
willful misconduct or gross negligence. The Parties, jointly and severally, shall indemnify,
defend and hold harmless the Escrow Agent from and against any and all loss, liability, cost,
damage and expense, including, without limitation, attorneys’ fees and expenses or other
professional fees and expenses which the Escrow Agent may suffer or incur by reason of any action,
claim or proceeding brought against the Escrow Agent, arising out of or relating in any way to this
Escrow Agreement or any transaction to which this Escrow Agreement relates, unless such loss,
liability, cost, damage or expense shall have been finally adjudicated to have been directly caused
by the willful misconduct or gross negligence of the Escrow Agent. The provisions of this Section
5.1 shall survive the resignation or removal of the Escrow Agent and the termination of this Escrow
Agreement.



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 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.




     Section 5.2 The Escrow Agent may resign as such following the giving of sixty (60) days’ prior
written notice to each of the Other Parties. Similarly, the Escrow Agent may be removed and
replaced following the giving of sixty (60) days’ prior written notice to the Escrow Agent jointly
by the Other Parties. In either event, the duties of the Escrow Agent shall terminate sixty (60)
days after the date of such notice (or at such earlier date as may be mutually agreeable), except
for its obligations to hold and deliver the Escrowed Property to the successor Escrow Agent; and
the Escrow Agent shall then deliver the balance of the Escrowed Property then in its possession to
such a successor Escrow Agent as shall be appointed by the Other Parties as evidenced by Joint
Instructions delivered to the Escrow Agent. Upon acknowledgment by any successor Escrow Agent of
the receipt of the then remaining Escrowed Property (or the deposit or delivery of the Escrowed
Property by the Escrow Agent pursuant to Section 5.4 below), the then acting Escrow Agent
shall be fully released and relieved of all duties, responsibilities and obligations under this
Escrow Agreement.



     Section 5.3 The Escrow Agent shall be under no duty to institute or defend any arbitration or
legal proceeding with respect to the Escrowed Property or under this Escrow Agreement and none of
the costs or expenses of any such proceeding shall be borne by the Escrow Agent. The costs and
expenses of any such proceeding shall be borne as decided by the arbitrators or court and shall be
direct obligations of the Other Parties, as the case may be, and shall not be satisfied in any way
by the Escrowed Property.



     Section 5.4 Should any controversy arise involving the parties hereto or any of them or any
other person with respect to this Escrow Agreement or the Escrowed



5









 







Property, or should a substitute escrow agent fail to be designated as provided in Section
5.2 hereof, or if the Escrow Agent should be in doubt as to what action to take, the Escrow
Agent shall have the right, but not the obligation, either to (a) withhold delivery of the Escrowed
Property until the controversy is resolved, the conflicting demands are withdrawn or its doubt is
resolved, (b) deposit all Escrowed Property into the registry of any court of competent
jurisdiction and notify the Other Parties of such deposit, and thereupon the Escrow Agent shall be
discharged from all further duties and responsibilities as Escrow Agent under this Escrow Agreement
or (c) file an interpleader action in any court of competent jurisdiction, and upon the filing
thereof and deposit of all Escrowed Property into the registry of such court, the Escrow Agent
shall be relieved of all liability as to the Escrowed Property and shall be entitled to recover
from the losing party of such action reasonable attorneys’ fees, expenses and other costs incurred
in commencing and maintaining any such interpleader action.
