hereto.

          3.4. This Escrow  Agreement is the final  expression  of, and contains
the entire  agreement  between,  the parties with respect to the subject  matter
hereof and supersedes all prior understandings with respect thereto. This Escrow

parties to be charged or by their  respective  agents duly authorized in writing
or as otherwise expressly permitted herein.

singular shall include the plural and masculine shall include the feminine. This

                                       3


prepared the same. Unless otherwise indicated, all references to Articles are to
this Escrow Agreement.

while acting in good faith,  excepting only its own gross  negligence or willful
misconduct,  and any act done or  omitted by the Escrow  Agent  pursuant  to the

and all  warnings  given by any of the parties  hereto or by any other person or
corporation,  excepting  only  orders or  process of courts of law and is hereby

court. In case the Escrow Agent obeys or complies with any such order,  judgment
or decree,  the Escrow Agent shall not be liable to any of the parties hereto or

Escrow Agent in connection  with the Escrow Agent's duties  hereunder,  may rely
upon  the  advice  of  such  counsel,   and  may  pay  such  counsel  reasonable
compensation  therefor.  The  Escrow  Agent has acted as legal  counsel  for the
Purchaser, and may continue to act as legal counsel for the Purchaser, from time
to time,  notwithstanding its duties as the Escrow Agent hereunder.  The Company
consents to the Escrow Agent in such capacity as legal counsel for the Purchaser
and waives any claim that such representation  represents a conflict of interest
on the part of the Escrow Agent. The Company  understands that the Purchaser and
the Escrow Agent are relying  explicitly on the foregoing  provision in entering
into this Escrow Agreement.

and the Company shall appoint a successor Escrow Agent.

          3.13.  If the  Escrow  Agent  reasonably  requires  other  or  further
instruments in connection  with this Escrow  Agreement or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

          3.14. It is  understood  and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
or the escrow  funds held by the Escrow  Agent  hereunder,  the Escrow  Agent is
authorized and directed in the Escrow  Agent's sole  discretion (i) to retain in
the Escrow  Agent's  possession  without  liability to anyone all or any part of
said  documents or the escrow funds until such disputes  shall have been settled
either by mutual  written  agreement of the parties  concerned by a final order,
decree  or  judgment  of  a  board  of  arbitration  or  a  court  of  competent
jurisdiction  after the time for  appeal  has  expired  and no  appeal  has been
perfected,  but the Escrow Agent shall be under no duty  whatsoever to institute
or defend  any such  proceedings,  or (ii) to deliver  the escrow  funds and any
other  property and documents  held by the Escrow Agent  hereunder to a state or
Federal court having  competent  subject matter  jurisdiction and located in the
State and City of New York in accordance with the applicable procedure therefor.

          3.15.  The Company and the  Purchaser  agree  jointly and severally to
indemnify and hold harmless the Escrow Agent and its partners, employees, agents
and  representatives  from any and all  claims,  liabilities,  costs or expenses
(including  reasonable  attorneys'  fees) in any way arising from or relating to
the duties or  performance  of the Escrow Agent  hereunder  or the  transactions
contemplated  hereby or by the  Purchase  Agreement  other than any such  claim,
liability,  cost or expense to the extent the same shall have been determined by
final,  unappealable  judgment  of a court  of  competent  jurisdiction  to have
resulted from the gross negligence or willful misconduct of the Escrow Agent.
