SECTION 1.01.  ...Creation of Senior Note Bank Bonds. The Company hereby creates
                  ----------------------------------
a series  of  bonds to be  issued  under  and  secured  by the  Mortgage,  to be
designated and distinguished  from bonds of all other series by the title "First
Mortgage  Bonds,  Senior  Note Bank  Series due 2002." The  aggregate  principal
amount of the Senior Note Bank Bonds which may be  initially  authenticated  and
delivered shall be limited to One Hundred Fifty Million Dollars  ($150,000,000),
shall mature on February 1, 2002, and shall be issued in denominations of $1,000
and any amount in excess thereof. The serial numbers of bonds of the Senior Note
Bank Bonds shall be such as may be approved by any officer of the  Company,  the
execution thereof by any such officer either manually or by facsimile  signature
to be  conclusive  evidence of such  approval.  The Senior Note Bank Bonds shall
bear  interest  at the rate of ten per centum  (10%) per annum;  interest  shall
accrue from and including the date of the first  authentication  and delivery of
the Senior Note Bank Bonds, except as otherwise provided in the form of bond set
forth in Article II hereof and shall be payable on each  Interest  Payment  Date
(as  defined in the Bank  Senior  Notes)  and at  maturity  or upon  redemption.
Interest  on the Senior Note Bank Bonds  during any period for which  payment is
made shall be  computed  in  accordance  with the Bank  Senior  Notes  until the
principal thereof shall have become due and payable. The regular record date for
the  interest  payable  on each  Interest  Payment  Date  shall  be the day next
preceding such Interest Payment Date. Interest payable at maturity shall be paid
to the person to whom  principal  shall be paid.  Interest  on overdue  interest
shall be payable at the rate per annum specified in this Section 1.01. Except as
provided in Sections 2.03, 2.04, 2.05, 8.03 and 17.04 of the Original Indenture,
no Senior  Note Bank  Bonds  shall be  authenticated  and  delivered  after such
initial issue.

      SECTION  1.02.  Dating of Senior Note Bank Bonds.  Each Senior Note Bank
                      --------------------------------
Bond shall be dated the date of its authentication.

      SECTION 1.03.  Payment of Principal  and  Interest.  The principal of, and
                     -----------------------------------
interest on any Senior Note Bank Bond shall be payable, in such coin or currency
of the United  States of America as at the time of payment shall be legal tender
for the  payment  of public  and  private  debts,  and shall be  payable  at the
"office" or agency of the Company in the Borough of  Manhattan,  The City of New
York.

      SECTION  1.04.  Credits with  Respect to Senior Note Bank Bonds.  Upon any

portion of the Bank  Senior  Notes,  whether at maturity or prior to maturity by
redemption or otherwise or upon  provision for the payment  thereof  having been
made in accordance  with Section  5.01(a) of the Senior Note  Indenture,  Senior
Note Bank Bonds in a principal amount equal to the principal amount of such Bank
Senior Notes shall, to the extent of such payment of principal, and interest, be
deemed paid and the  obligation  of the Company  thereunder to make such payment
shall be discharged to such extent and, in the case of the payment of principal,
the Senior  Note Bank Bonds in an equal  principal  amount of the  related  Bank


                                        6




Senior Notes shall be surrendered to the Company for cancellation as provided in
Section  4.06 of the Senior Note  Indenture.  The Trustee may at anytime and all
times  conclusively  assume that the  obligation of the Company to make payments
with respect to the principal of, and interest on the Senior Note Bank Bonds, so
far as such  payments at the time have become due, has been fully  satisfied and
discharged pursuant to the foregoing sentence unless and until the Trustee shall
have received a written notice from the Senior Note Trustee signed by one of its
officers stating (i) that timely payment of, or premium or interest on, the Bank
Senior Notes has not been so made, (ii) that the Company is in arrears as to the
payments  required to be made by it to the Senior Note  Trustee  pursuant to the
Senior Note Indenture, and (iii) the amount of the arrearage.

      SECTION  1.05.  Registration  of Senior Note Bank Bonds.  Senior Note Bank
                      ---------------------------------------
Bonds are to be  issued to and  registered  in the name of United  States  Trust
Company of New York, as the Senior Note Trustee, or a successor trustee thereto,
under the Senior Note Indenture to secure any and all obligations of the Company
under the Bank Senior  Notes and any other  series of Senior  Notes from time to
time outstanding under the Senior Note Indenture.

      SECTION 1.06. Transferability and Assignability of Senior Note Bank Bonds.

competent  jurisdiction  in connection  with any  bankruptcy  or  reorganization
proceeding of the Company, the Senior Note Bank Bonds are not transferable.  The
Senior Note Bank Bonds shall 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. The Company covenants and agrees that, notwithstanding Section 2.03 of the
Original  Indenture,  it will not charge any sum for or in  connection  with any
exchange or  transfer of any Senior Note Bank Bond,  but may require the payment
of a sum  sufficient  to cover  any tax or taxes or other  governmental  charges
incident to any exchange, transfer or registration thereof.

      SECTION  1.07.  Redemption  of Senior  Note Bank  Bonds.  Senior Note Bank

the principal  amount thereof,  plus interest accrued to the redemption date, in
whole,  upon a written demand for redemption by the Senior Note Trustee  stating
that (i) the Bank  Senior  Notes  have been  called for  redemption  or (ii) the
principal of all Senior Notes then  outstanding  under the Senior Note Indenture
have been declared to be immediately due and payable  pursuant to the provisions
of the first sentence of Section 8.01(a) thereof.

      This bond is one of an issue of bonds of the Company (hereinafter referred
to as the "bonds"),  not limited in principal amount,  issuable in series, which
different  series may mature at different  times, may bear interest at different
rates, and may otherwise vary as in the Mortgage hereinafter mentioned provided,
and is one of a series  known as its  First  Mortgage  Bonds,  Senior  Note Bank
Series due 2002 (herein  called the "Senior Note Bank Bonds"),  all bonds of all
series  issued and to be issued  under and equally and ratably  secured  (except
insofar as any sinking fund or analogous  fund,  established in accordance  with
the  provisions of the Mortgage  hereinafter  mentioned,  may afford  additional
security  for the  bonds of any  particular  series)  by an  Indenture  (herein,
together with any indentures  supplemental thereto, called the "Mortgage") dated
November 1, 1944,  executed by the Company to UNITED STATES TRUST COMPANY OF NEW
YORK, as successor  Trustee to GUARANTY TRUST COMPANY OF NEW YORK (herein called
the  "Trustee"),  to which  reference is made for a description  of the property
mortgaged  and pledged,  the nature and extent of the  security,  the rights and
limitations  of rights of the holders of the bonds and of the Company in respect
thereof,  the rights,  duties and  immunities of the Trustee,  and the terms and
conditions  upon which the bonds are,  and are to be,  issued and  secured.  The
Senior Note Bank Bonds are described in the  Supplemental  Indenture dated as of
May 1, 2001, between the Company and the Trustee (the "Supplemental Indenture").

      Under  an  Indenture  dated  as of July  1,  1999  (hereinafter  sometimes
referred  to as the  "Senior  Note  Indenture"),  between the Company and United
Trust Company of New York, as trustee (hereinafter  sometimes called the "Senior
Note Trustee"),  the Company will issue,  concurrently with the issuance of this
bond, an issue of notes under the Senior Note Indenture  entitled  Senior Notes,
Bank Series (the "Bank Senior Notes"). Pursuant to Article IV of the Senior Note
Indenture,  this bond is issued to the Senior Note Trustee to secure any and all
obligations  of the Company  under the Bank Senior Notes and any other series of
senior  notes from time to time  outstanding  under the Senior  Note  Indenture.
Payment of principal of, or interest on, the Bank Senior Notes shall  constitute
payments  on this  bond  as  further  provided  herein  and in the  Supplemental
Indenture.

      Interest on this bond shall be computed in accordance with the Bank Senior
Notes.

      Upon any payment of the  principal of, and interest on, all or any portion
of the Bank Senior Notes, whether at maturity or prior to maturity by redemption
or  otherwise  or upon  provision  for the payment  thereof  having been made in
accordance with Section  5.01(a) of the Senior Note Indenture,  Senior Note Bank
Bonds in a principal  amount equal to the  principal  amount of such Bank Senior
Notes shall, to the extent of such payment of principal and interest,  be deemed
paid and the obligation of the Company  thereunder to make such payment shall be
discharged  to such extent and,  in the case of the  payment of  principal  such
bonds of said series shall be  surrendered  to the Company for  cancellation  as
provided  in Section  4.06 of the Senior  Note  Indenture.  The  Trustee  may at
anytime and all times conclusively  assume that the obligation of the Company to
make  payments with respect to the principal of, and interest on the Senior Note
Bank Bonds,  so far as such payments at the time have become due, has been fully
satisfied and discharged pursuant to the foregoing sentence unless and until the
Trustee shall have received a written notice from the Senior Note Trustee signed
by one of its  officers  stating  (i) that  timely  payment of  principal  of or
interest on, the Bank Senior  Notes has not been made,  (ii) that the Company is
in  arrears as to the  payments  required  to be made by it to the  Senior  Note
Trustee  pursuant  to the  Senior  Note  Indenture,  and (iii) the amount of the
arrearage.
                                        9





      For purposes of Section 4.07 of the Senior Note Indenture, this bond shall
be deemed to be the  "Related  Series of Senior  Note First  Mortgage  Bonds" in
respect of the Bank Senior Notes.

      The Mortgage contains  provisions  permitting the Company and the Trustee,
with the consent of the holders of not less than  seventy-five per cent (75%) in
principal  amount  of all the  bonds  at the  time  outstanding  (determined  as
provided in the Mortgage) evidenced as in the Mortgage provided,  or in case the
rights under the Mortgage of the holders of bonds of one or more,  but less than
all, of the series of bonds outstanding shall be affected, then with the consent
of the  holders of not less than  seventy-five  per centime  (75%) in  principal
amount of the bonds at the time  outstanding of the series affected  (determined
as provided in the Mortgage)  evidenced as in the Mortgage provided,  to execute
supplemental  indentures  adding any  provisions to or changing in any manner or
eliminating any of the provisions of the Mortgage or modifying in any manner the
rights of the holders of the bonds and coupons thereunto appertaining; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any bonds,  or reduce  the rate or extend  the time of  payment  of  interest
thereon,  or reduce the  principal  amount  thereof,  without the consent of the
holder of each bond so  affected,  or (ii) reduce the  aforesaid  percentage  of
bonds,  the holders of which are  required  to consent to any such  supplemental
indenture without the consent of the holders of all bonds then outstanding.  Any
such consent by the registered holder of this bond (unless  effectively  revoked
as provided in the Mortgage)  shall be  conclusive  and binding upon such holder
and upon all future  holders of this  bond,  irrespective  of whether or not any
notation of such waiver or consent is made upon this bond.

      No  reference  herein to the  Mortgage and no provision of this bond or of
the  Mortgage  shall alter or impair the  obligation  of the  Company,  which is
absolute and unconditional, to pay the principal of and interest on this bond at
the  time  and  place  and  at the  rate  and in the  coin  or  currency  herein
prescribed.

      The Senior Note Bank Bonds are issuable only in fully  registered  form in
denominations of $1,000 and any amount in excess thereof.

      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
be called for redemption, and premium, if any, thereon, and all interest payable
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  Senior  Note  Bank  Bonds  shall be  redeemable  as  provided  in the
Supplemental Indenture.

      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
the Mortgage provided.

                                       10





      This  bond  is not  transferable  except  (i) as  required  to  effect  an
assignment to a successor Trustee under the Senior Note Indenture, (ii) pursuant
to  Section  4.03 or  Section  4.06 of the Senior  Note  Indenture,  or (iii) in
compliance with a final order of a court of competent jurisdiction in connection
with any bankruptcy or reorganization proceeding of the Company. This bond shall
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,  stockholder,  officer or
director,  as such,  of the  Company  or of any  successor  corporation,  either
directly or through the Company or any successor corporation,  under any rule of
law,  statute  or  constitution  or by  the  enforcement  of any  assessment  or
otherwise,  all such  liability  of  incorporators,  subscribers,  stockholders,
officers  and  directors,  as such,  being waived and released by the holder and
owner  hereof  by the  acceptance  of this bond and being  likewise  waived  and
released by the terms of the Mortgage.

      This bond shall not  become  valid or  obligatory  for any  purpose  until
UNITED STATES TRUST COMPANY OF NEW YORK, the Trustee under the Mortgage,  or its
successor  thereunder,  shall have  signed  the  certificate  of  authentication
endorsed hereon.
