         The form of the Trustee's Certificate of Authentication for the Series

         Each Series B 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
have the meanings set forth in the Original Indenture.

         "Attributable Debt" means in respect of a Sale and Lease-Back
Transaction, as at the time of determination, the present value (discounted at
the interest rate borne by the Series B Notes) of the total obligations of the
lessee for rental payments during the remaining term of the lease included in
such Sale and Lease-Back Transaction (including any period for which such lease
has been extended).

         "Consolidated Net Tangible Assets" means the total of all assets
(including revaluations thereof as a result of commercial appraisals, price
level restatement or otherwise) appearing on a consolidated balance sheet of the
Company, net of applicable reserves and deductions, but excluding goodwill,
trade names, trademarks, patents, unamortized debt discount and all other like
intangible assets (which term shall not be construed to include such
revaluations), less the aggregate of the consolidated current liabilities of the
Company appearing on such balance sheet.

         "Interest Payment Dates" means March 31, June 30, September 30, and
December 31 of each year.

         "Original Issue Date" means February 26, 1998.

         "Regular Record Date" means, with respect to each Interest Payment

                                       2



         "Stated Maturity" means December 31, 2047.

         SECTION 103. Payment of Principal and Interest. The unpaid principal
amount of the Series B Notes shall bear interest at the rate of 7% per annum
until paid or duly provided for. Interest shall be paid quarterly in arrears on
each Interest Payment Date to the Person in whose name the Series B 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 will be paid to the Person to whom principal is payable.
Any such interest that is not so punctually paid or duly provided for will
forthwith cease to be payable to the Holders on such Regular Record Date and may
either be paid to the Person or Persons in whose name the Series B Notes are
registered at the close of business on a Special Record Date for the payment of
such defaulted interest to be fixed by the Trustee, notice whereof shall be
given to Holders of the Series B Notes not less than ten (10) days prior to such
Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange, if any, on which
the Series B Notes shall be listed, and upon such notice as may be required by
any such exchange, all as more fully provided in the Original Indenture.

         Payments of interest on the Series B Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series B 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 B Notes is not a Business Day, then a payment
of the interest payable on such date will be made on the next succeeding day
that is a Business Day, except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date the payment was originally payable.

         Payment of the principal and interest due at the Stated Maturity or
earlier redemption of the Series B Notes shall be made upon surrender of the
Series B Notes at the Corporate Trust Office of the Trustee, 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 interest (including
interest on any Interest Payment Date) will be made, subject to such surrender
where applicable, at the option of the Company, (i) by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register or (ii) 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 B Notes may be issued in the
denominations of $25, or any integral multiple thereof.

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

                                      3


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.

         Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series B Note shall be exchangeable, except for
another Global Security of like denomination and tenor to be registered in the
name of the Depositary or its nominee or to a successor Depositary or its
nominee. The rights of Holders of such Global Security shall be exercised only
through the Depositary.

         A Global Security shall be exchangeable for Series B Notes registered
in the names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company 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 Company, or if at any time the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, as
amended, 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
Company, in each case within 90 days after the Company receives such notice or
becomes aware of such cessation, (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable, or (iii) there
shall have occurred an Event of Default with respect to the Series B Notes. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series B Notes registered in such names as the Depositary shall
direct.

         SECTION 106. Transfer. No service charge will be made for any transfer
or exchange of Series B Notes, but payment will be required of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.

         The Company shall not be required (a) to issue, transfer or exchange
any Series B Notes during a period beginning at the opening of business fifteen
(15) days before the day of the mailing of a notice identifying the serial
numbers of the Series B Notes to be called for redemption, and ending at the
close of business on the day of the mailing, or (b) to transfer or exchange any
Series B Notes theretofore selected for redemption in whole or in part, except
the unredeemed portion of any Series B Note redeemed in part.

         SECTION 107. Redemption. The Series B Notes shall be subject to
redemption at the option of the Company, in whole or in part, without premium or
penalty, at any time or from time to time on or after February 26, 2003, at a
Redemption Price equal to 100% of the principal amount to be redeemed plus
accrued but unpaid interest to the Redemption Date.

         In the event of redemption of the Series B Notes in part only, a new
Series B Note or Notes for the unredeemed portion will be issued in the name or
names of the Holders thereof upon the surrender thereof.

         The Series B Notes will not have a sinking fund.

         Notice of redemption shall be given as provided in Section 1104 of the
Original Indenture.





                                       4

         Any redemption of less than all of the Series B Notes shall, with
respect to the principal thereof, be divisible by $25.

         SECTION 108. Limitation on Sale and Lease-Back Transactions. So long as
any Series B Notes remain Outstanding, the Company shall not enter into any
arrangement with any Person providing for the leasing by the Company of any
assets which have been or are to be sold or transferred by the Company to such
Person (a "Sale and Lease-Back Transaction") unless: (i) such transaction
involves a lease for a temporary period not to exceed three years; (ii) such
transaction is between the Company and an Affiliate of the Company; (iii) such
transaction is entered into within 60 days after the initial acquisition by the
Company of the assets or property subject to such transaction; (iv) after giving
effect thereto, the aggregate amount of all Attributable Debt with respect to
all such Sale and Lease-Back Transactions does not exceed 10% of Consolidated
Net Tangible Assets; or (v) within the twelve months preceding the sale or
transfer or the twelve months following the sale or transfer, the Company
applies, in the case of a sale or transfer for cash, an amount equal to the net
proceeds thereof and, in the case of a sale or transfer otherwise than for cash,
an amount equal to the fair value of the assets so leased at the time of
entering into such arrangement (as determined by the Board of Directors), (a) to
the retirement of indebtedness for money borrowed, incurred or assumed by the
Company which by its terms matures at, or is extendible or renewable at the
option of the obligor to, a date more than twelve months after the date of
incurring, assuming or guaranteeing such debt or (b) to investment in any assets
of the Company.

         This Section 108 is expressly being included in the Original Indenture
by this Second Supplemental Indenture solely for the benefit of the Holders of
the Series B Notes.

Supplemental Indenture shall be read, taken and construed as one and the same

                             (Reverse Side of Note)


         This Note is one of a duly authorized issue of Senior Notes of the
Company (the "Notes"), issued and issuable in one or more series under a Senior
Note Indenture, dated as of December 1, 1997, as supplemented (the "Indenture"),
between the Company and The Chase Manhattan Bank, Trustee (the "Trustee," which
term includes any successor trustee under the Indenture), to which Indenture and
all indentures incidental thereto reference is hereby made for a statement of
the respective rights, limitation of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Notes issued thereunder and of
the terms upon which said Notes are, and are to be, authenticated and delivered.
This Note is one of the series designated on the face hereof as Series B 7%
Senior Quarterly Interest Notes due December 31, 2047 (the "Series B Notes") in
the aggregate principal amount of up to $200,000,000. Capitalized terms used
herein for which no definition is provided herein shall have the meanings set
forth in the Indenture.

         The Company shall have the right, subject to the terms and conditions
of the Indenture, to redeem this Note at any time on or after February 26, 2003
at the option of the Company, without premium or penalty, in whole or in part,
at a Redemption Price equal to 100% of the principal amount to be redeemed plus
accrued but unpaid interest to the Redemption Date.

          In the event of redemption of this Note in part only, a new Note or
Notes of this series for the unredeemed  portion hereof will be issued in the
name of the Holder hereof upon the surrender hereof. The Notes will not have a 
sinking fund.

         If an Event of Default with respect to the Notes of this series shall
occur and be continuing, the principal of the Notes 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
Company and the rights of the Holders of the Notes of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in principal amount of the Notes at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Notes of each series at the time Outstanding, on behalf of the Holders of
all Notes of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
