the Original Indenture, as may be amended and supplemented to the date hereof,
including by this Fifth Supplemental Indenture, is herein called the
"Indenture";

   WHEREAS, under the Indenture, a new series of Securities may at any time be
established in accordance with the provisions of the Indenture and the terms of

   WHEREAS, the Corporation proposes to create under the Indenture a series of
Securities;

   WHEREAS, additional Securities of other series hereafter established, except
as may be limited in the Indenture as at the time supplemented and modified,
may be issued from time to time pursuant to the Indenture as at the time
supplemented and modified; and

   WHEREAS, all conditions necessary to authorize the execution and delivery of
this Fifth Supplemental Indenture and to make it a valid and binding obligation

   NOW, THEREFORE, in consideration of the agreements and obligations set forth
herein and for other good and valuable consideration, the sufficiency of which

   Section 103. Payment of Principal and Interest. The principal of the ROARS
shall be due at the Stated Maturity (unless the ROARS are earlier redeemed or
repurchased). The ROARS shall bear

                                       7

<PAGE>

interest at the rate of 7 1/8% per annum, for the period from the Original
Issue Date to but excluding the first Remarketing Date, such interest to be
paid semiannually to and including the first Remarketing Date on September 3
and March 3 of each year, commencing March 3, 2001. Interest on the ROARS
accruing to the first Remarketing Date shall be computed on the basis of a
360-day year of twelve 30-day months.

   The ROARS shall bear interest from and after the Fixed Rate Remarketing Date
at a rate per annum equal to the Interest Rate to Maturity, such interest to be
paid semiannually on each day that is a six-month anniversary of such Fixed

Remarketing Date shall be computed on the basis of a 360-day year consisting of
twelve 30-day months.

   The ROARS shall bear interest during the Floating Rate Period at the
Floating Period Interest Rate with respect to each Floating Rate Reset Period.
The amount of interest payable for each day that the ROARS are Outstanding
during the Floating Rate Period shall be calculated by dividing the Floating
Period Interest Rate in effect for such day by 360 and multiplying the result
by the Dollar Price. The amount of interest payable for any Floating Rate Reset
Period shall be calculated by adding the interest payable for each day in the
Floating Rate Reset Period. Interest on the ROARS accruing during any Floating
Rate Reset Period shall be payable on the next following Reference Rate Reset
Date if such date is a Business Day or otherwise on the next following Business
Day. Interest on the ROARS accruing during the Floating Rate Period shall be
computed on the basis of the actual number of days in such Floating Rate Reset
Period over a 360-day year.

   Except as otherwise provided herein, interest on the ROARS payable on any
Interest Payment Date shall be payable to the Persons in whose names the ROARS
are registered on the Regular Record Date for such Interest Payment Date.
Interest payable on any Interest Payment Date shall accrue from and including
the next preceding Interest Payment Date (or from and including the Original
Issue Date if no interest has been paid or duly provided with respect to the
ROARS) to but excluding the relevant Interest Payment Date, Remarketing Date or
the Stated Maturity, as the case may be. If any Interest Payment Date, the
Stated Maturity or other payment date of the ROARS (including any payment date
in connection with the mandatory tender or any mandatory redemption of the
ROARS) does not fall on a Business Day, the payment otherwise payable on that
date shall be made on the next succeeding day that is a Business Day with the
same force and effect as if made on the date the payment was originally
payable, and no interest shall accrue for the period from and after such
Interest Payment Date, Stated Maturity or other payment date, except in the
case of an Interest Payment Date or other payment date occurring during the
Floating Rate Period.

   Section 104. Mandatory Tender; Remarketing and Determination of Interest
Rate.

   Mandatory Tender. On a Business Day not earlier than 20 Business Days prior
to the first Remarketing Date, and not later than 4:00 p.m., New York City
time, on the 15th Business Day prior to such Remarketing Date or not later than
four Business Days prior to the occurrence of the subsequent Remarketing Date,
the Remarketing Dealer shall notify the Corporation and the Trustee as to
whether it elects to purchase the ROARS for remarketing on such Remarketing
Date.

  If the Remarketing Dealer so elects, the ROARS shall be subject to mandatory
tender, and shall be deemed tendered, to the Remarketing Dealer for purchase
and remarketing on such Remarketing Date, in accordance with the terms and
subject to the conditions described herein.

                                       8

<PAGE>

  The ROARS shall be remarketed at a fixed rate of interest equal to the
Interest Rate to Maturity, unless the Corporation has elected to exercise its
Floating Period Option or redeem the ROARS on the applicable Remarketing Date.
If the Corporation so elects, the ROARS shall bear interest at the Floating
Period Interest Rate until the Floating Period Termination Date, at which time
the ROARS shall be remarketed at a fixed rate of interest equal to the Interest
Rate to Maturity unless the Corporation has chosen to redeem, or is required to
redeem, the ROARS, as set forth herein.

  The purchase price of the tendered ROARS shall be equal to 100% of the
aggregate principal amount thereof on the first Remarketing Date, or the Dollar
Price on the subsequent Remarketing Date.

  Subject to the Remarketing Dealer's election to purchase the ROARS, the
Remarketing Dealer shall sell the aggregate principal amount of the ROARS on
the applicable Remarketing Date at the Dollar Price to the Reference Corporate
Dealer providing the lowest Fixed Rate Bid (if the Remarketing Date constitutes
a Fixed Rate Remarketing Date) or to the Reference Money Market Dealer
providing the lowest Floating Rate Bid (if the Remarketing Date constitutes a
Floating Rate Remarketing Date), in the case of the first Remarketing Date, or
to the Reference Corporate Dealer providing the lowest Fixed Rate Bid, in the
case of the subsequent Remarketing Date. If the lowest applicable Bid is
submitted by two or more of the applicable Reference Dealers, the Remarketing
Dealer shall sell such ROARS to one or more of such Reference Dealers, as it
shall determine in its sole discretion.

  If the Remarketing Dealer elects to purchase the ROARS, the obligation of the
Remarketing Dealer to purchase the ROARS on any Remarketing Date shall be
subject to certain conditions set forth in the Remarketing Agreement.

  If for any reason the Remarketing Dealer does not purchase the ROARS on any
Remarketing Date, the Corporation shall be required to redeem the ROARS in
accordance with Section 105 at a price equal to 100% of the aggregate principal
amount of the ROARS, plus accrued and unpaid interest, if any, if such
Remarketing Date is the first Remarketing Date, or at the Dollar Price, plus
accrued and unpaid interest, if any, on the subsequent Remarketing Date.

  Remarketing. The interest rates on the ROARS shall be established by the
Remarketing Dealer in accordance with the following procedures.

  Interest Rate to Maturity: If the Remarketing Dealer elects to purchase the
ROARS on the first Remarketing Date, then by 3:30 p.m., New York City time, on
the Floating Rate Spread Determination Date or the Fixed Rate Determination
Date with respect to the first Remarketing Date, depending on the following
election, the Remarketing Dealer shall determine the Floating Rate Spread in
the case that the Corporation has elected to exercise its Floating Period
Option, or otherwise the Interest Rate to Maturity to the nearest one hundredth
(0.01) of one percent per annum unless the Corporation has elected to redeem
the ROARS by optional redemption, or is required to redeem the ROARS by
mandatory redemption. If there is a subsequent Remarketing Date, by 3:30 p.m.,
New York City time, on the related Fixed Rate Determination Date, the
Remarketing Dealer shall determine the Interest Rate to Maturity to the nearest
one hundredth (0.01) of one percent per annum unless the Corporation elects or
is required to redeem the ROARS as aforesaid. On the

                                       9

<PAGE>

Floating Rate Spread Determination Date or the Fixed Rate Determination Date
with respect to the first Remarketing Date, the Remarketing Dealer shall
determine the Dollar Price. The Interest Rate to Maturity and the Dollar Price
for the ROARS announced by the Remarketing Dealer, absent manifest error, shall
be binding and conclusive upon the Holders, the holders of beneficial interests
in the ROARS, the Corporation and the Trustee, and the Trustee shall have no
responsibility for the calculation thereof.

  Floating Rate Period: Following the Remarketing Dealer's election to purchase
the ROARS on the first Remarketing Date, but prior to the fourth Business Day
preceding such Remarketing Date, the Corporation may elect to exercise its
Floating Period Option. If the Corporation makes such election, the ROARS shall
bear interest at the Floating Period Interest Rate until the Floating Period
Termination Date. In the event that the Corporation elects to exercise its
Floating Period Option, the Stated Maturity of the ROARS shall be extended to
the tenth anniversary of the Fixed Rate Remarketing Date.

  The amount of the interest payable for each day that the ROARS are
Outstanding during the Floating Rate Period shall be calculated by dividing the
Floating Period Interest Rate in effect for such day by 360 and multiplying the
result by the Dollar Price. The amount of interest payable for any Floating
Rate Reset Period shall be calculated by adding the daily interest amounts for
each day in the Floating Rate Reset Period. The Floating Period Interest Rate
for the ROARS announced by the Remarketing Dealer, absent manifest error, shall
be binding and conclusive upon the Holders, the holders of beneficial interests
in the ROARS, the Corporation and the Trustee, and the Trustee shall have no
responsibility for the calculation thereof. The interest rate in effect with
respect to each Floating Rate Reset Period shall be the Floating Period
Interest Rate determined for such period on the preceding Reference Rate
Determination Date.

  Notification: Subject, in connection with the first Remarketing Date, to the
Remarketing Dealer's election to remarket the ROARS and to the Corporation's
election not to exercise its Floating Period Option, as set forth in this
Section 104, and in connection with the subsequent Remarketing Date, to the
Remarketing Dealer's election to remarket the ROARS, the Remarketing Dealer
shall notify the Corporation, the Trustee and the Depositary by telephone,
confirmed in writing (which confirmation may be by facsimile or other
electronic transmission), by 4:00 p.m., New York City time, on the Fixed Rate
Determination Date of the Interest Rate to Maturity of the ROARS effective from
and including the Fixed Rate Remarketing Date. The Remarketing Dealer shall
notify the Trustee of the Dollar Price and of the Floating Period Interest Rate
with respect to each Floating Rate Reset Period promptly after the
determination thereof. The Corporation shall promptly notify the Remarketing
Dealer and the Trustee of its election to exercise its Floating Period Option
or to terminate the Floating Rate Period.

  Redetermination of Interest Rates in Certain Events: Notwithstanding any
provision herein to the contrary, in lieu of terminating the Remarketing
Agreement pursuant to Section 11(b) thereof, upon the occurrence of any of the
events set forth therein, the Remarketing Dealer, in its sole discretion at any
time between any Determination Date and 2:00 p.m., New York City time, on the
Business Day immediately preceding the applicable Remarketing Date, may elect
to purchase the ROARS for remarketing and determine a new Floating Period
Interest Rate or Interest Rate to Maturity, as the

                                       10

<PAGE>

case may be, in the manner provided in this Section 104, except that for
purposes of determining the new Floating Period Interest Rate or Interest Rate
to Maturity, as the case may be, pursuant to this paragraph the Determination
Date referred to therein shall be the date of such election and
redetermination. The Remarketing Dealer shall notify the Corporation, the
Trustee and the Depositary by telephone, confirmed in writing (which
confirmation may be by facsimile or other electronic transmission), by 4:00
p.m., New York City time, on the date of such election, of the new Floating
Period Interest Rate or Interest Rate to Maturity, as the case may be, of the
ROARS. Thereupon, such new Floating Period Interest Rate or Interest Rate to
Maturity shall supersede and replace any Floating Period Interest Rate or
Interest Rate to Maturity previously determined by the Remarketing Dealer and,
absent manifest error, shall be binding and conclusive upon the Holders of, and
holders of beneficial interests in, the ROARS on and after such Remarketing
Date, the Corporation and the Trustee; provided that the Remarketing Dealer, by
redetermining the Floating Period Interest Rate or Interest Rate to Maturity
upon the occurrence of any event set forth in Section 11(b) of the Remarketing
Agreement, shall not thereby be deemed to have waived its right to determine a
new Floating Period Interest Rate or Interest Rate to Maturity or to terminate
the Remarketing Agreement upon the occurrence of any other event set forth in
such Section 11(b).

   Section 105. Redemption.

  Mandatory Redemption. Subject to the last paragraph of Section 104, the
Corporation shall redeem the ROARS in whole on the applicable Remarketing Date
at a price equal to 100% of the aggregate principal amount of the ROARS, if
such Remarketing Date is the first Remarketing Date, or the Dollar Price on any
subsequent Remarketing Date, plus accrued and unpaid interest, if any, to such
Remarketing Date, in the event that (i) the Remarketing Dealer for any reason
does not notify the Corporation of the Floating Period Interest Rate or of the
Interest Rate to Maturity by 4:00 p.m., New York City time, on the applicable
Determination Date; (ii) prior to any Remarketing Date, the Remarketing Dealer
resigns and no successor has been appointed on or before such Determination
Date; (iii) at any time after the Remarketing Dealer elects on the applicable
Notification Date to remarket such ROARS, the Remarketing Dealer elects to
terminate the Remarketing Agreement in accordance with its terms; (iv) the
Remarketing Dealer for any reason does not elect by notice to the Corporation
and the Trustee not later than such Notification Date, to purchase the ROARS
for remarketing on such Remarketing Date; (v) the Remarketing Dealer for any
reason does not deliver the purchase price of such ROARS to the Trustee in same
day funds not later than 12:00 noon, New York City time, on such Remarketing
Date, or does not purchase all tendered ROARS on such Remarketing Date; or (vi)
the Corporation for any reason fails to redeem the ROARS from the Remarketing
Dealer following the Corporation's election to effect such optional redemption
as set forth in the next succeeding subsection. Notwithstanding Section 1104 of
the Original Indenture, the Corporation shall not be required to give notice of
any such mandatory redemption to the Holders of, or the holders of beneficial
interests in, the ROARS.

  Optional Redemption. If the Remarketing Dealer elects to purchase the ROARS,
the Corporation may at its option redeem the ROARS, in whole but not in part,
on the first Remarketing Date or on the Floating Period Termination Date
immediately following the Determination Date with respect to such election. The
Corporation shall notify the Remarketing Dealer and the Trustee, not later than
4:00 p.m., New York City time, on the Business Day immediately preceding the
applicable

                                       11

<PAGE>

Determination Date if the Corporation elects to redeem the ROARS (which
election shall be irrevocable) in accordance herewith. If the Corporation
exercises its right to redeem the ROARS, the Corporation shall redeem the
ROARS, in whole but not in part, on the first Remarketing Date or the
subsequent Remarketing Date, as the case may be, at the Dollar Price, plus all
accrued and unpaid interest, if any, to such Remarketing Date. Notwithstanding
Section 1104 of the Original Indenture, no notice of redemption need be
provided to the Holders of, or the holders of beneficial interests in, the
ROARS with respect to any such redemption.

  Post-Remarketing Optional Redemption. The ROARS shall be redeemable, in whole
or in part, at any time after the Fixed Rate Remarketing Date, at the
Corporation's option, at a Redemption Price equal to the greater of:

    (1) 100% of the principal amount of the ROARS to be redeemed, or

    (2) the sum of the present values of the remaining scheduled payments of
  principal and interest thereon (not including any portion of such payments
  of interest accrued as of the Redemption Date) discounted to such
  Redemption Date on a semiannual basis (assuming a 360-day year consisting
  of twelve 30-day months) at the Adjusted Treasury Rate, plus 20 basis
  points as calculated by an Independent Investment Banker, plus, in either
  case, accrued and unpaid interest thereon to the Redemption Date.

The Adjusted Treasury Rate shall be calculated on the third Business Day
preceding the applicable Redemption Date.

  The Corporation shall give the Trustee notice of the Redemption Price with
respect to any redemption pursuant to this subsection of Section 105 promptly
after the calculation thereof and the Trustee shall have no responsibility for
any such calculation. Notice of any redemption pursuant to this subsection of
Section 105 shall be given as provided in Section 1104 of the Original
Indenture, except that such notice need not set forth the Redemption Price but
only the manner of calculation thereof.

  In the event of the redemption of the ROARS in part only, one or more new
ROARS for the unredeemed portion shall be issued in the name or names of the
Holders thereof upon surrender of the ROARS that are to be partially redeemed.

   The ROARS shall not have a sinking fund.

   Section 106. Denominations. The ROARS shall be issued in denominations of
$1,000 or any integral multiple thereof.

   Section 107. Global Securities. The ROARS shall initially be issued in the
form of one or more Global Securities registered in the name of the Depositary
(which initially shall be The Depository Trust Company) or its nominee. Except
under the limited circumstances described below, ROARS represented by such
Global Security or Global Securities shall not be exchangeable for, and shall
not otherwise be issuable as, ROARS in definitive form. The Global Securities
described above may not be transferred except by the Depositary to a nominee of
the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or to a successor Depositary or its nominee.

                                       12

<PAGE>

   A Global Security shall be exchangeable for ROARS registered in the names of
Persons other than the Depositary or its nominee only if the Depositary
notifies the Corporation that it is unwilling or unable to continue as
Depositary for such Global Security and no successor Depositary shall have been
appointed by the Corporation within 90 days of receipt by the Corporation of
such notification, or if at any time the Depositary ceases to be a clearing
agency registered under the Exchange Act at a time when the Depositary is
required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Corporation within 90 days after it
becomes aware of such cessation. The Corporation waives any discretionary right
it otherwise has under Section 305 of the Original Indenture to cause the ROARS
to be issued in certificated form and agrees to use its reasonable best efforts
to maintain the ROARS in book-entry form with DTC or any successor Depositary
and to appoint a successor Depositary to the extent necessary to maintain the
ROARS in book-entry form. Any Global Security that is exchangeable pursuant to
the preceding sentence shall be exchangeable for ROARS registered in such names
as the Depositary shall direct.

   Section 108. Paying Agent. The Trustee shall initially serve as Paying Agent
with respect to the ROARS, with the Place of Payment initially being the
Corporate Trust Office.

   Section 109. Amendments; Modifications. The Corporation covenants, for the
benefit of the Remarketing Dealer only, that this Fifth Supplemental Indenture
shall not be amended for the purpose of changing any of the terms or provisions
of the ROARS or changing any other provisions of this Fifth Supplemental
Indenture without the prior written consent of the Remarketing Dealer (it being
understood that, notwithstanding the provisions of this Section 109, the
Corporation shall not be precluded from amending the Indenture in any manner
whatsoever so long as the amendment does not pertain exclusively to the ROARS).

   Section 110. Purchases by Corporation. The Corporation agrees that it shall
not, without the prior written consent of the Remarketing Dealer, make any open
market or other purchases of the ROARS prior to the first Remarketing Date or
termination of the Remarketing Agreement, whichever is earlier.

remain primarily liable for the performance of all such obligations.

   IN WITNESS WHEREOF, each party hereto has caused this instrument to be
signed in its name and behalf by its duly authorized officers, all as of the
day and year first above written.

be computed on the basis of a 360-day year of twelve 30-day months from the
Original Issue Date to the first Remarketing Date and then, subject to the
Remarketing Dealer's election to remarket and the Corporation's election to
exercise its Floating Period Option, interest on this Security shall be computed

Period over a 360-day year until the Fixed Rate Remarketing Date. Interest shall
be computed on the basis of a 360-day year of twelve 30-day months from the
Fixed Rate Remarketing to the Stated Maturity. If any Interest Payment Date, the
Stated Maturity or other payment date of this Security (including any payment
date in connection with the mandatory tender or any mandatory redemption of this
Security) does not fall on a Business Day, the payment otherwise payable on that
date shall be made on the next succeeding day that is a Business Day with the
same force and effect as if made on the date the payment was originally payable,
and no interest shall accrue for the period from and after such Interest Payment
Date, Stated Maturity or other payment date, except in the case of an Interest
Payment Date or other payment date occurring during the Floating Rate Period.

on which banking institutions in New York, New York are authorized or obligated
by law or executive order to remain closed.

     Payment of principal of, premium, if any, and interest on the Securities of
this series shall be made in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. Payments of principal of, premium, if any, and interest on
Securities of this series represented by a Global Security shall be made by wire
transfer of immediately available funds to the Holder of such Global Security,

                          (Reverse Side of Security)

     This Security is one of a duly authorized issue of Securities of the
Corporation (the "Securities"), issued and issuable in one or more series under
a Senior Indenture, dated as of September 1, 1998, as supplemented (the
"Indenture"), between the Corporation and The Chase Manhattan Bank, as Trustee
(the "Trustee," which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitation of rights, duties and
immunities thereunder of the Corporation, the Trustee and the Holders of the
Securities issued thereunder and of the terms upon which said Securities are,
and are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof as 7-1/8% Remarketable or Redeemable Securities
(ROARS(SM)) Due 2012, initially in the aggregate principal amount of
$250,000,000. Capitalized terms used herein for which no definition is provided
herein shall have the meanings set forth in the Indenture.

     Certain provisions relating to the remarketing of the Securities of this
series which are set forth in the Indenture are contained in a Remarketing
Agreement (the "Remarketing Agreement") between the Corporation and UBS AG,
London Branch, as Remarketing Dealer (with any successor Remarketing Dealer, the
"Remarketing Dealer").

     The Securities of this series are subject to tender and remarketing as set
forth in the Indenture.

     The Securities of this series may be subject to mandatory redemption or
redemption at the option of the Corporation as set forth in the Indenture.

     If an Event of Default with respect to the Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the

Corporation and the Trustee;

   WHEREAS, the Corporation proposes to create under the Indenture a series of
Securities;

   WHEREAS, additional Securities of other series hereafter established, except

supplemented and modified; and

   WHEREAS, all conditions necessary to authorize the execution and delivery of
this    Supplemental Indenture and to make it a valid and binding obligation of
the Corporation have been done or performed.

   NOW, THEREFORE, in consideration of the agreements and obligations set forth
herein and for other good and valuable consideration, the sufficiency of which
is hereby acknowledged, the parties hereto hereby agree as follows:

                                   ARTICLE 1

                             Series  % Senior Notes

   Section 101. Establishment. There is hereby established a new series of
Securities to be issued under the Indenture, to be designated as the
Corporation's Series  % Senior Notes due      (the "Series   Notes").

   There are to be authenticated and delivered $      principal amount of
Series   Notes, and no further Series   Notes shall be authenticated and
delivered except as provided by Section 304, 305, 306, 906 or 1106 of the
Original Indenture. The Series   Notes shall be issued in fully registered form
without coupons.

   The Series   Notes shall be in substantially the form set out in Exhibit A
hereto, and the form of the Trustee's Certificate of Authentication for the
Series   Notes shall be in substantially the form set forth in Exhibit B
hereto.

                                       1
<PAGE>

   Each Series   Note shall be dated the date of authentication thereof and
shall bear interest from the date of original issuance thereof or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for.

   Section 102. Definitions. The following defined terms used herein shall,
unless the context otherwise requires, have the meanings specified below.
Capitalized terms used herein for which no definition is provided herein shall

   Section 103. Payment of Principal and Interest. The principal of the Series
   Notes shall be due at Stated Maturity (unless earlier redeemed). The unpaid
principal amount of the Series   Notes shall bear interest at the rate of  %
per annum until paid or duly provided for, such interest to accrue from
        ,     or from the most recent Interest Payment Date to which interest
has been paid or duly provided for. Interest shall be paid semiannually in

the Series   Notes are registered on the Regular Record Date for such Interest
Payment Date; provided that interest payable at the Stated Maturity of
principal or on a Redemption Date as provided herein shall be paid to the
Person to whom principal is payable. Any such interest that is not so

any such exchange, all as more fully provided in the Original Indenture.

   Payments of interest on the Series   Notes shall include interest accrued to
but excluding the respective Interest Payment Dates. Interest payments for the
Series   Notes shall be computed and paid on the basis of a 360-day year of
twelve 30-day months. In the event that any date on which interest is payable
on the Series   Notes is not a Business Day, then payment of the interest
payable on such date shall be made on the next succeeding day that is a
Business Day (and without any interest or payment in respect of any such delay)
with the same force and effect as if made on the date the payment was
originally payable. "Business Day" means a day other than (i) a Saturday or a
Sunday, (ii) a day on which banking institutions in New York, New York are
authorized or obligated by law or executive order to remain closed or (iii) a

represented by a Global Security shall be made by wire transfer of immediately
available funds to the Holder of such Global Security, provided that, in the
case of payments of principal and premium, if any, such Global Security is
first surrendered to the Paying Agent. If any of the Series   Notes are no
longer represented by a Global Security, (i) payments of principal, premium, if
any, and interest due at the Stated Maturity or earlier redemption of such
Series   Notes shall be made at the office of the Paying Agent upon surrender
of such Series  Notes to the Paying Agent and (ii) payments of interest shall

applicable, (A) by check mailed to the address of the Person entitled thereto
as such address shall appear in the Security Register or (B) by wire transfer
at such place and to such account at a banking institution in the United States
as may be designated in writing to the Trustee at least sixteen (16) days prior
to the date for payment by the Person entitled thereto.

   Section 104. Denominations. The Series   Notes shall be issued in
denominations of $     or any integral multiple thereof.

   Section 105. Global Securities. The Series   Notes shall initially be issued
in the form of one or more Global Securities registered in the name of the
Depositary (which initially shall be The Depository Trust Company) or its
nominee. Except under the limited circumstances described below, Series   Notes
represented by such Global Security or Global Securities shall not be
exchangeable for, and shall not otherwise be issuable as, Series   Notes in
definitive form. The Global Securities described above may not be transferred
except by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or to a
successor Depositary or its nominee.

   A Global Security shall be exchangeable for Series   Notes registered in the
names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Corporation that it is unwilling or unable to continue
as a Depositary for such Global Security and no successor Depositary shall have
been appointed by the Corporation within 90 days of receipt by the Corporation
of such notification, or if at any time the Depositary ceases to be a clearing
agency registered under the Exchange Act at a time when the Depositary is
required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Corporation within 90 days after it
becomes aware of such cessation or (ii) the Corporation in its sole discretion
determines that such Global Security shall be so exchangeable. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series   Notes registered in such names as the Depositary
shall direct.

   Section 106. Redemption at the Option of the Corporation. The Series   Notes
shall be redeemable, in whole or from time to time in part, at the option of
the Corporation on any date (a "Redemption Date"), at a Redemption Price equal
to the greater of (i) 100% of the principal amount of the Series   Notes to be
redeemed and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest thereon (exclusive of interest accrued to
such Redemption Date) discounted to such Redemption Date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate plus    basis points, plus, in either case, accrued and unpaid interest on
the principal amount being redeemed to such Redemption Date.

                                       3
<PAGE>

   "Treasury Rate" means, with respect to any Redemption Date for the Series
Notes, (i) the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication which
is published weekly by the Board of Governors of the Federal Reserve System and
which establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption "Treasury Constant Maturities,"
for the maturity corresponding to the Comparable Treasury Issue (if no maturity
is within three months before or after the Stated Maturity, yields for the two
published maturities most closely corresponding to the Comparable Treasury
Issue shall be determined, and the Treasury Rate shall be interpolated or
extrapolated from such yields on a straight-line basis, rounding to the nearest
month) or (ii) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields,
the rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be
calculated on the third Business Day preceding the Redemption Date.

   "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable
to the remaining term of the Series   Notes to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Series   Notes.

   "Independent Investment Banker" means      and any successor firm or, if
such firm is unwilling or unable to select the Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by
the Trustee after consultation with the Corporation.

   "Comparable Treasury Price" means, with respect to any Redemption Date for
the Series   Notes, (i) the average of      Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest
such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer
than    such Reference Treasury Dealer Quotations, the average of all such
quotations.

   "Reference Treasury Dealer" means each of      ,      ,      ,     and
and their respective successors; provided, however, that if any of the
foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), the Corporation will substitute
therefor another Primary Treasury Dealer.

   "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third Business Day preceding such Redemption Date.

   Notwithstanding Section 1104 of the Original Indenture, the notice of
redemption with respect to the foregoing redemption need not set forth the
Redemption Price but only the manner of calculation thereof.

                                       4
<PAGE>

   The Corporation shall notify the Trustee of the Redemption Price with
respect to the foregoing redemption promptly after the calculation thereof. The
Trustee shall not be responsible for calculating said Redemption Price.

   If less than all of the Series   Notes are to be redeemed, the Trustee shall
select the Series   Notes or portions of Series   Notes to be redeemed by such
method as the Trustee shall deem fair and appropriate. The Trustee may select
for redemption Series   Notes and portions of Series   Notes in amounts of
whole multiples of $    .

   The Series   Notes shall not have a sinking fund.

   Section 107. Paying Agent. The Trustee shall initially serve as Paying Agent
with respect to the Series   Notes, with the Place of Payment initially being
the Corporate Trust Office.

                                   ARTICLE 2

   This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

                                          The Chase Manhattan Bank,
                                            as Trustee

                                             ----------------------------------

                           (Reverse Side of Security)

   This Security is one of a duly authorized issue of Securities of the
Corporation (the "Securities"), issued and issuable in one or more series under
a Senior Indenture, dated as of September 1, 1998, as supplemented (the
"Indenture"), between the Corporation and The Chase Manhattan Bank, as Trustee
(the "Trustee," which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitation of rights, duties and
immunities thereunder of the Corporation, the Trustee and the Holders of the
Securities issued thereunder and of the terms upon which said Securities are,
and are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof as Series  % Senior Notes due     in the
aggregate principal amount of $       . Capitalized terms used herein for which
no definition is provided herein shall have the meanings set forth in the
Indenture.

   The Securities of this series will be redeemable, in whole or from time to
time in part, at the option of the Corporation on any date (a "Redemption
Date"), at a Redemption Price equal to the greater of (i) 100% of the principal
amount of the Securities of this series to be redeemed and (ii) the sum of the
present values of the remaining scheduled payments of principal and interest
thereon (exclusive of interest accrued to such Redemption Date) discounted to
such Redemption Date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate plus      basis points, plus, in
either case, accrued and unpaid interest on the principal amount being redeemed
to such Redemption Date.

   "Treasury Rate" means, with respect to any Redemption Date for the
Securities of this series, (i) the yield, under the heading which represents
the average for the immediately preceding week, appearing in the most recently
published statistical release designated "H.15(519)" or any successor
publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption "Treasury
Constant Maturities," for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the Stated
Maturity, yields for the two published maturities most closely corresponding to
the Comparable Treasury Issue shall be determined, and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (ii) if such release (or any successor
release) is not published during the week preceding the calculation date or
does not contain such yields, the rate per annum equal to the semiannual
equivalent yield to maturity of the Comparable Treasury Issue, calculated using
a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such Redemption
Date. The Treasury Rate shall be calculated on the third Business Day preceding
the Redemption Date.

                                      A-3

   "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable
to the remaining term of the Securities of this series to be redeemed that
would be utilized, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of such Securities of this series.

   "Independent Investment Banker" means          and any successor firm or, if
such firm is unwilling or unable to select the Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by
the Trustee after consultation with the Corporation.

   "Comparable Treasury Price" means with respect to any Redemption Date for
the Securities of this series (i) the average of      Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest
such Reference Treasury Dealer Quotations or (ii) if the Trustee obtains fewer
than      such Reference Treasury Dealer Quotations, the average of all such
quotations.

   "Reference Treasury Dealer" means each of         ,           ,         ,
        and          and their respective successors; provided, however, that
if any of the foregoing shall cease to be a primary U.S. Government securities
dealer in New York City (a "Primary Treasury Dealer"), the Corporation will
substitute therefor another Primary Treasury Dealer.

   "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its prinicpal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third Business Day preceding such Redemption Date.

   Notice of any redemption by the Corporation will be mailed at least 30 days
but not more than 60 days before any Redemption Date to each Holder of
Securities of this series to be redeemed. If less than all the Securities of
this series are to be redeemed at the option of the Corporation, the Trustee
shall select, in such manner as it shall deem fair and appropriate, the
Securities of this series to be redeemed in whole or in part. The Trustee may
select for redemption Securities of this series and portions of Securities of
this series in amounts of whole multiples of $     .

   In the event of redemption of this Security in part only, a new Security or
Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the surrender hereof.

   If an Event of Default with respect to the Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

   The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Corporation and the rights of the Holders of the Securities of all series
affected under the Indenture at any time by the Corporation and the Trustee
with the consent of the Holders of not less than a majority in principal amount
of the Outstanding

                                      A-4
<PAGE>

Securities of all series affected thereby (voting as one class). The Indenture
contains provisions permitting the Holders of not less than a majority in
principal amount of the Outstanding Securities of all series with respect to
which a default under the Indenture shall have occurred and be continuing
(voting as one class), on behalf of the Holders of the Securities of all such
series, to waive, with certain exceptions, such default under the Indenture and
its consequences. The Indenture also permits the Holders of not less than a
majority in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Corporation with certain provisions of the Indenture
affecting such series. Any such consent or waiver by the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Security and of any Security issued upon the registration of
transfer hereof or in exchange hereof or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

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

   As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation for such purpose, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Corporation and
the Security Registrar and duly executed by, the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Securities of this
series, of authorized denominations and of like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

   The Indenture contains provisions for defeasance at any time of the entire
indebtedness of the Securities of this series and for covenant defeasance at
any time of certain covenants in the Indenture upon compliance with certain
conditions set forth in the Indenture.

   Prior to due presentment of this Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security be overdue, and neither the
Corporation, the Trustee nor any such agent shall be affected by notice to the
contrary.

   The Securities of this series are issuable only in registered form without
coupons in denominations of $    and any integral multiple thereof. As provided
in the Indenture and subject to the limitations therein set forth, Securities
of this series are exchangeable for a like aggregate principal amount of
Securities of this series of a different authorized denomination, as requested
by the Holder surrendering the same upon surrender of the Security or
Securities to be exchanged at the office or agency of the Corporation.

   This Security shall be governed by, and construed in accordance with, the
internal laws of the State of New York.
