the Senior Note  Trustee,  as the holder of the Senior Note Series -- Bonds,  as
provided in the Mortgage.

      The Mortgage  provides  that if the Company shall deposit with the Trustee
in trust for the purpose  funds  sufficient  to pay the  principal of all of the
bonds of any  series,  or such of the bonds of any series as have been or are to

on such bonds to the date on which they become due and  payable,  at maturity or
upon  redemption  or otherwise,  and complies  with the other  provisions of the
Mortgage in respect thereof, then from the date of such deposit such bonds shall
no longer be entitled to any lien or benefit under the Mortgage.

      The  principal  hereof  may be  declared  or may  become  due prior to the
express date of the maturity hereof on the conditions,  in the manner and at the
time set forth in the Mortgage, upon the occurrence of a completed default as in

assignment to a successor Trustee under the Senior Note Indenture, (ii) pursuant
to  Section  4.05 or  Section  4.08 of the Senior  Note  Indenture,  or (iii) in

be exchangeable  for other  registered bonds of the same series and for the same
aggregate principal amount, in the manner and upon the conditions  prescribed in
the Mortgage,  upon the surrender of such bonds at the "office" or agency of the
Company  in  the  Borough  of  Manhattan,   the  City  of  New  York.   However,
notwithstanding the provisions of Section 2.05 of the Mortgage,  no charge shall
be made upon any  registration  of  transfer or exchange of bonds of said series
other than for any tax or taxes or other governmental charge required to be paid
by the  Company.  The Company  and the  Trustee,  any paying  agent and any bond
registrar may deem and treat the person in whose name this bond is registered as
the absolute  owner hereof,  whether or not this bond shall be overdue,  for the
purpose of receiving  payment and for all other purposes and neither the Company
nor the Trustee nor any paying agent nor any bond registrar shall be affected by
any notice to the contrary.

      No recourse  shall be had for the payment of the  principal of or interest
on this bond, or for any claim based hereon,  or otherwise in respect hereof, or
based on or in respect of the Mortgage,  against any  incorporator  or any past,
present or future subscriber to the capital stock,
