      and Responsibilities of the Escrow Agent .
      The
      Escrow Agent's duties and responsibilities shall be subject to the following
      terms and conditions:




(a)  The
      Parties acknowledge and agree that the Escrow Agent (i) shall not be responsible
      for or bound by, and shall not be required to inquire into whether any of the
      Parties is entitled to receipt of the Stockholder Documents and Optionee
      Documents pursuant to, any other agreement or otherwise; (ii) shall be obligated
      only for the performance of such duties as are specifically assumed by the
      Escrow Agent pursuant to this Agreement; (iii) may rely on and shall be
      protected in acting or refraining from acting upon any written notice,
      instruction, instrument, statement, request or document furnished to it
      hereunder and believed by the Escrow Agent in good faith to be genuine and
      to
      have been signed or presented by the proper person or party, without being
      required to determine the authenticity or correctness of any fact stated therein
      or the propriety or validity or the service thereof; (iv) may assume that any
      person believed by the Escrow Agent in good faith to be authorized to give
      notice or make any statement or execute any document in connection with the
      provisions hereof is so authorized; (v) shall not be under any duty to give
      the
      property held by Escrow Agent hereunder any greater degree of care than Escrow
      Agent gives its own similar property; and (vi) may consult counsel satisfactory
      to Escrow Agent, the opinion of such counsel to be full and complete
      authorization and protection in respect of any action taken, suffered or omitted
      by Escrow Agent hereunder in good faith and in accordance with the opinion
      of
      such counsel.




(b)  The
      Parties acknowledge that the Escrow Agent is acting solely as a stakeholder
      at
      their request and that the Escrow Agent shall not be liable for any action
      taken
      by Escrow Agent in good faith and believed by Escrow Agent to be authorized
      or
      within the rights or powers conferred upon Escrow Agent by this Agreement.
      The
      Stockholders and Optionees, jointly and severally, agree to indemnify and hold
      harmless the Escrow Agent and any of Escrow Agent's partners, employees, agents
      and representatives for any action taken or omitted to be taken by Escrow Agent
      or any of them hereunder, including the fees of outside counsel and other costs
      and expenses of defending itself against any claim or liability under this
      Agreement, except in the case of gross negligence or willful misconduct on
      Escrow Agent's part committed in its capacity as Escrow Agent under this
      Agreement. The Escrow Agent shall owe a duty only to the Stockholders and
      Optionees under this Agreement and to no other person.




(c)  The
      Stockholders and Optionees, jointly and severally agree to reimburse the Escrow
      Agent for outside counsel fees, to the extent authorized hereunder and incurred
      in connection with the performance of its duties and responsibilities
      hereunder.




(d)  The
      Escrow Agent may at any time resign as Escrow Agent hereunder by giving five
      (5)
      days prior written notice of resignation to the Parties. Prior to the effective
      date of the resignation as specified in such notice, the Stockholders and
      Optionees will issue to the Escrow Agent a Joint Instruction authorizing
      delivery of the Stockholder Documents and Optionee Documents to a substitute
      Escrow Agent selected by the Optionees and Stockholders. If no successor Escrow
      Agent is named by the Optionees and Stockholders, the Escrow Agent may apply
      to
      a court of competent jurisdiction in the State of New York for appointment
      of a
      successor Escrow Agent, and to deposit the Stockholder Documents and Optionee
      Documents with the clerk of any such court.




(e)  The
      Escrow Agent does not have and will not have any interest in the Stockholder
      Documents and Optionee Documents, but is serving only as escrow agent, having
      only possession thereof. The Escrow Agent shall not be liable for any loss
      resulting from the making or retention of any investment in accordance with
      this
      Escrow Agreement.







(f)  This
      Agreement sets forth exclusively the duties of the Escrow Agent with respect
      to
      any and all matters pertinent thereto and no implied duties or obligations
      shall
      be read into this Agreement.




(g)  The
      Escrow Agent shall be permitted to act as counsel for the Optionees in any
      dispute as to the disposition of the Stockholder Documents and Optionee
      Documents, in any other dispute between the Parties, whether or not the Escrow
      Agent is then holding the Stockholder Documents and Optionee Documents and
      continues to act as the Escrow Agent hereunder.




(h)  The
      provisions of this Section 4.1 shall survive the resignation of the Escrow
      Agent
      or the termination of this Agreement.




4.2.  Dispute
      Resolution: Judgments .
      Resolution of disputes arising under this Agreement shall be subject to the
      following terms and conditions:




(a)  If
      any
      dispute shall arise with respect to the delivery, ownership, right of possession
      or disposition of the Stockholder Documents and Optionee Documents, or if the
      Escrow Agent shall in good faith be uncertain as to its duties or rights
      hereunder, the Escrow Agent shall be authorized, without liability to anyone,
      to
      (i) refrain from taking any action other than to continue to hold the
      Stockholder Documents and Optionee Documents pending receipt of a Joint
      Instruction from Stockholders and the Optionees, or (ii) deposit the Stockholder
      Documents and Optionee Documents with any court of competent jurisdiction in
      the
      State of New York, in which event the Escrow Agent shall give written notice
      thereof to the Stockholders and Optionees and shall thereupon be relieved and
      discharged from all further obligations pursuant to this Agreement. The Escrow
      Agent may, but shall be under no duty to, institute or defend any legal
      proceedings which relate to the Stockholder Documents and Optionee Documents.
      The Escrow Agent shall have the right to retain counsel if it becomes involved
      in any disagreement, dispute or litigation on account of this Agreement or
      otherwise determines that it is necessary to consult counsel.




(b)  The
      Escrow Agent is hereby expressly authorized to comply with and obey any Court
      Order. In case the Escrow Agent obeys or complies with a Court Order, the Escrow
      Agent shall not be liable to the Parties or to any other person, firm,
      corporation or entity by reason of such compliance.
