principal amount of $250,000,000 (the “Notes”).

     

    All
things necessary to make the Notes, when executed by the Company and
authenticated and delivered hereunder and under the Base Indenture and duly
issued by the Company and to make this Supplemental Indenture a valid agreement
of the Company, in accordance with their and its terms, respectively, have been
done.

     

    NOW,
THEREFORE, this Supplemental Indenture WITNESSETH:

the extent that payment of such interest or Additional Amounts is lawful,
interest upon overdue interest and any Additional Amount at the rate borne by

5.01. Reports.  In addition to
the covenants set forth in Article 10 of the Base Indenture, the Company
covenants and agrees for the benefit of the Holders of the Notes, and whether or
not required by the rules and regulations of the Commission, that so long as any
Notes are Outstanding, the Company shall file with the Commission, to the extent
such filings are accepted by the Commission, and shall furnish (within 15 days
after such filing) to the Trustee and to the Holders of the Notes all quarterly
and annual reports and other information, documents and reports that would be
required to be filed with the Commission pursuant to Section 13 of the Exchange

the Base Indenture, the Company covenants and agrees for the benefit of the
Holders of the Notes that the Company shall not issue, incur, create, assume or
guarantee any Indebtedness secured by a Lien upon any Principal Property or upon
any of the Capital Stock or Indebtedness of any of its Significant Subsidiaries
(whether such Principal Property, or Capital Stock or Indebtedness is now
existing or owed or is hereafter created or acquired) without in any such case
effectively providing, concurrently with the issuance, incurrence, creation,
assumption or guaranty of any such secured Indebtedness, or the grant of such
Lien, that the Notes (together, if the Company shall so determine, with any
other Indebtedness of or guarantee by the Company ranking equally with the
Notes) shall be secured equally and ratably with (or, at the Company’s option,
prior to) such secured Indebtedness. The foregoing restriction, however, shall
not apply to any of the following:

     

    (a)        Liens
existing on the Issue Date;

     

    (b)        Liens
on assets or property of a Person at the time it becomes a Subsidiary, securing

not extend to any assets other than those of the Person becoming a
Subsidiary;

     

    (c)        Liens
on property or assets of a Person existing at the time such Person is merged
into or consolidated with the Company or any of its Subsidiaries, or at the time
of a sale, lease or other disposition of all or substantially all of the
properties or assets of a Person to the Company or any of its Subsidiaries,
provided that such Lien was not incurred in anticipation of the merger,
consolidation, or sale, lease, other disposition or other such transaction by
which such Person was merged into or consolidated with the Company or any of its
Subsidiaries;

    (d)        Liens
existing on assets created at the time of, or within the 12 months following,
the acquisition, purchase, lease, improvement or development of such assets to
secure all or a portion of the purchase price or lease for, or the costs of
improvement or development of (in each case including related costs and
expenses), such assets;

     

    (e)        Liens
to secure any extension, renewal, refinancing or refunding (or successive
extensions, renewals, refinancings or refundings), in whole or in part, of any
Indebtedness secured by Liens referred to in Sections 5.02(a), (b), (c) and (d)
above, so long as such Lien is limited to all or part of substantially the same
property which secured the Lien extended, renewed or replaced, and the amount of
Indebtedness secured is not increased (other than by the amount equal to any
costs and expenses (including any premiums, fees or penalties) incurred in
connection with any extension, renewal, refinancing or refunding);

     

    (f)        Liens
for taxes not yet due or that are being contested in good faith by appropriate
proceedings, provided that adequate reserves with respect thereto are maintained
on the books of the Company in conformity with generally accepted accounting
principles;

     

    (g)        Liens
imposed by law, such as carriers’, warehousemen’s, mechanics’, materialmen’s,
repairmen’s or other like Liens arising in the ordinary course of business that
are not overdue for a period of more than 30 days or that are being contested in
good faith by appropriate proceedings;

     

    (h)        Liens
to secure the performance of bids, trade contracts, leases, statutory
obligations, surety and appeal bonds, performance bonds and other obligations of
a like nature incurred in the ordinary course of business; 

     

    (i)        Liens

in favor of the Trustee securing Indebtedness owed under the Indenture to the
Trustee and granted in accordance with the Indenture; and

     

    (k)        Liens
to secure Hedging Obligations.

the foregoing, the Company shall be permitted to incur Indebtedness, secured by
Liens otherwise prohibited by this Section 5.02, which, together with the value
of Attributable Debt outstanding pursuant to the last paragraph of Section 5.03
hereof, do not exceed 15% of Consolidated Net Tangible Assets measured at the
date of incurrence of the Lien.

     

    Section
5.03.  Limitations upon Sales and
Lease-Backs.  The Company shall not enter into any Sale and
Lease-Back Transaction with respect to any Principal Property, other than any
such Sale and Lease-Back Transaction

    involving
a lease for a term of not more than three years or any such Sale and Lease-Back
Transaction between the Company and one of its Subsidiaries or between the
Company’s Subsidiaries, unless:

     

    (a)        the
Company or such Subsidiary would be entitled to incur Indebtedness secured by a
Lien on the Principal Property involved in such Sale and Lease-Back Transaction
at least equal in amount to the Attributable Debt with respect to such Sale and
Lease-Back Transaction, without equally and ratably securing the Notes, pursuant
to Section 5.02 hereof; or

     

    (b)        the
proceeds of such Sale and Lease-Back Transaction are at least equal to the fair
market value of the affected Principal Property (as determined in good faith by
the Board of Directors) and the Company applies an amount equal to the net
proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale
and Lease-Back Transaction to any (or a combination) of (i) the prepayment or
retirement of the Notes, (ii) the prepayment or retirement (other than any
mandatory retirement, mandatory prepayment or sinking fund payment or by payment
at maturity) of other Indebtedness of the Company or of one of its Subsidiaries
(other than Indebtedness that is subordinated to the Notes or Indebtedness owed
to the Company or one of its Subsidiaries) that matures more than 12 months
after its creation or (iii) the purchase, construction, development, expansion
or improvement of other comparable property.

     

    Notwithstanding
the restrictions in this Section 5.03, the Company shall be permitted to enter
into Sale and Lease-Back Transactions otherwise prohibited by this Section 5.03,
which, together with all Indebtedness outstanding pursuant to the last paragraph
of Section 5.02 hereof, do not exceed 15% of Consolidated Net Tangible Assets
measured at the closing date of the Sale and Lease-Back
Transaction.

     

    Section
5.04.  Repurchase of
Notes upon a Change of Control Triggering Event.  (a) If a
Change of Control Triggering Event occurs, unless the Company has exercised its
right to redeem the Notes pursuant to Section 3.01 hereof, the Company shall be
required to make an offer to repurchase all or, at the Holder’s option, any part
(equal to $2,000 or any multiple of $1,000 in excess thereof), of each Holder’s
Notes pursuant to the offer described in Section 5.04(b) below (the “Change of Control Offer”). In
the Change of Control Offer, the Company shall be required to offer payment in
cash equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest, if any, on the Notes repurchased, to, but not
including, the date of purchase (the “Change of Control Payment”),
subject to the rights of Holders of the Notes on the relevant Regular Record
Date to receive interest due on the relevant Interest Payment Date.

    (b)        Within
30 days following any Change of Control Triggering Event, the Company shall be
required to mail a notice to Holders of the Notes, with a copy to the Trustee,
describing the transaction or transactions that constitute the Change of Control
Triggering Event and offering to repurchase the Notes on the date specified in
the notice, which date shall be no earlier than 30 days and no later than 60
days from the date such notice is mailed (the “Change of Control Payment
Date”), pursuant to the procedures specified herein and described in such
notice. The Company shall comply with the requirements of applicable securities
laws and regulations in connection with the repurchase of the Notes as a result
of a Change of Control Triggering Event.

     

    (c)        On
the Change of Control Payment Date, the Company shall be required, to the extent
lawful, to (1) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof properly tendered and (3) deliver or cause to be delivered
to the Trustee the Notes so accepted together with an Officer’s Certificate

each such Holder, a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each new Note
shall be issued in a principal amount of $2,000 or a multiple of $1,000 in
excess thereof.

     

    (d)        The
Company shall not be required to make a Change of Control Offer upon a Change of
Control Triggering Event if a third party makes such an offer in the manner, at
the times and otherwise in compliance with the requirements for an offer made by
the Company and such third party purchases all Notes properly tendered and not
withdrawn under its offer.  In the event that such third party
terminates or defaults its offer, the Company shall be required to make a Change
of Control Offer treating the date of such termination or default as though it
were the date of the Change of Control Triggering Event.

     

    (e)        The
Company shall comply with the requirements of Rule 14e-1 under the Exchange Act
and other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Notes as a
result of a Change of Control Triggering Event.  To the extent that
the provisions of any securities laws or regulations conflict with this Section
5.04, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 5.04 by virtue thereof.

    [REVERSE
OF NOTE]

     

    5.625%
SENIOR NOTES DUE 2021

     

    1.      Indenture.  The
Company issued this Note pursuant to an Indenture dated as of August 1, 1998
(the “Base Indenture”),
as supplemented by a Supplemental Indenture No. 3 dated as of November 23, 2009
(the “Supplemental
Indenture” and together with the Base Indenture, the “Indenture”), between the
Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the
“Trustee,” which term
includes any successor trustee under the Indenture).  This Note is one
of a duly authorized issue of Notes of the Company designated as its 5.625%
Senior Notes due 2021.  The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act.  Notwithstanding anything to the contrary herein, the
Notes are subject to all such terms, and Holders of Notes are referred to the
Indenture and the Trust Indenture Act for a statement of such
terms.  The Notes are senior unsecured obligations of the
Company.

     

    Each
Holder, by accepting a Note, agrees to be bound by all of the terms and
provisions of the Indenture, as the same may be amended from time to
time.

     

    2.      Interest.  The
Company promises to pay interest on the principal amount of this Note at a rate
of 5.625% per annum.  Interest on the Notes shall accrue from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, or if no interest has been paid, from the Issue Date.  The
Company shall pay interest semi-annually in arrears on each Interest Payment
Date, commencing on May 15, 2010, until the principal hereof is paid or duly
provided for.  Interest shall be computed and paid on the basis of a
360-day year comprised of twelve 30-day months.

     

    If any
Interest Payment Date or the Maturity Date falls on a day that is not a Business
Day, principal or interest payable with respect to such Interest Payment Date or
Maturity Date, as the case may be, shall be paid on the next succeeding Business
Day with the same force and effect as if it were paid on the date such payment
was due, and no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date or the Maturity Date, as the case may
be.

     

    Any such
interest not so punctually paid or duly provided for shall forthwith cease to be
payable to the registered Holder on such Regular Record Date and may either be
paid (i) to the Person in whose name this Note is 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 of which shall be given to Holders of Notes not
less than 10 days prior to such Special Record Date or (ii) at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Notes of this series may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

     

    3.      Method of
Payment.  The Company shall pay interest on the Notes (except
Defaulted Interest) to the Persons who are the registered Holders at the close
of business on the Regular Record Date for such interest, which shall be the May
1 or November 1 (whether or not such day is a Business Day), immediately
preceding the Interest Payment Date even if the Notes 

     

     

    
      
        
        

      

      
        A-5

        
          

        

      

      
        
        

      

    

     

    are
canceled on registration of transfer or registration of exchange after such
Regular Record Date.

     

    All
payments of principal of, and any interest on the Notes issued in global form
shall be made to the Depository as the registered holder thereof.  The
Company expects that the Depository, upon receipt of payment of principal or
interest on such Note, will credit the accounts of persons who have accounts
with the Depository (the “participants”) with payment of
principal or interest on the date payable in amounts proportionate to their
respective beneficial interests in the principal amount of such Note as shown on
the records of the Depository.  The Company also expects that payments
by participants to owners of beneficial interests in any Note held through such
participants will be governed by standing instructions and customary
practices.  Such payments shall be the responsibility of such
participants.

     

    The
Company is obligated to make payment of principal, premium, if any, and interest
in respect of this Note in United States dollars.  The Company may, at
its option, pay principal, premium, if any, and interest by wire transfer in
U.S. legal tender.  The Company may deliver any interest payment by
check mailed to the address of the Person entitled thereto as such address shall
appear on the Security Register.

     

    4.      Paying Agent and
Registrar.  The Company shall at all times appoint and maintain
a Paying Agent (which may be the Trustee) authorized by the Company to pay the
principal, premium, if any, and interest on the Notes on behalf of the Company
and having an office or agency in New York, New York (the “Place of Payment”) where Notes
may be presented or surrendered for payment and where notices, designations or
requests with respect to the Notes may be served.  The Company has
initially appointed the Trustee to act as Paying Agent and
Registrar.  The Company may change the Paying Agent or Registrar
without notice to the Holders.  Neither the Company nor any of its
Subsidiaries or Affiliates may act as Paying Agent, although such entities may
act as Registrar.

     

    5.      Optional
Redemption.  The Company may redeem the Notes, in whole or in
part, at the Company’s option, at any time and from time to time prior to
maturity on at least 30 days’, but not more than 60 days’, prior notice at the
Redemption Price equal to the greater of: (i) 100% of the principal amount of
the Notes to be redeemed; and (ii) the sum of the present values of the
Remaining Scheduled Payments, discounted, on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at a rate equal to the sum of
the Treasury Rate plus 40 basis points plus, in each case, accrued and unpaid
interest on the Notes to the Redemption Date; provided that the principal amount
of a Note remaining outstanding after redemption in part shall be $2,000 or an
integral multiple of $1,000 in excess thereof.

     

    If less
than all of the Notes are to be redeemed at any time, selection of the Notes to
be redeemed shall be made by the Trustee from among the Outstanding Notes on a
pro rata basis, by lot
or by any other method permitted in the Indenture.  On and after the
Redemption Date, interest shall cease to accrue on the Notes or portions thereof
called for redemption.

     

    The Notes
will not be entitled to any sinking fund.

     

     

    
      
        
        

      

      
        A-6

        
          

        

      

      
        
        

      

    

     

    6.      Notice of
Redemption.  Notice of redemption under the preceding paragraph
of this Note shall be mailed at least 30 days but not more than 60 days before
the Redemption Date to each Holder of Notes to be redeemed at such Holder’s
registered address.

     

    Except as
set forth in the Indenture, if monies for the redemption of the Notes called for
redemption shall have been deposited with the Paying Agent for redemption on
such Redemption Date, then the Notes called for redemption shall cease to bear
interest from and after such Redemption Date and the only right of the Holders
of such Notes shall be to receive payment of the Redemption Price plus interest
accrued through the Redemption Date, if any.

     

    7.      Offers to Repurchase Upon Changes of
Control Triggering Event.  The Indenture provides that, upon
the occurrence of a Change of Control Triggering Event, and if the Company has
not previously redeemed all or any portion of the Notes, the Company shall be
required to make an offer to repurchase all or, at the Holder’s option, any part
of each Holder’s Notes in accordance with the procedures set forth in the
Indenture.

     

    8.      Denominations; Transfer;
Exchange.  The Notes are in definitive, fully registered form,
without coupons, in minimum denominations of U.S. $2,000 and in integral
multiples of U.S. $1,000 in excess thereof.  A Holder shall register
the transfer or exchange of Notes in accordance with the Indenture and the
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents in connection therewith as permitted by the
Indenture.  No service charge shall be made for any such registration
of transfer or exchange, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.
The Registrar need not register the transfer of or exchange of any Notes or
portions thereof selected for redemption.

     

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

     

    10.    Unclaimed
Money.  If money for the payment of principal or interest
remains unclaimed for two years (or such shorter period for the return of such
moneys to the Company under applicable abandoned property laws), the Trustee and
the Paying Agent shall pay the money back to the Company upon written
request.  After that, Holders entitled to money must look to the
Company for payment as general creditors unless an “abandoned property” law
designates another person.

     

    11.     Defeasance and Covenant
Defeasance.  The Indenture contains provisions for defeasance
at any time of (i) the entire indebtedness of this Note or (ii) certain
respective covenants and Events of Default with respect to this Note, in each
case upon compliance with certain conditions set forth therein, which provisions
apply to the Notes.

     

    At the
option of the Company and upon satisfaction of certain conditions specified in
the Indenture, either (a) the Company shall be deemed to have paid and
discharged the entire indebtedness on the Notes or (b) the Company need not
comply with certain covenants contained 

     

     

    
      
        
        

      

      
        A-7

        
          

        

      

      
        
        

      

    

     

    in the
Indenture, in each case upon the deposit by the Company with the Trustee in
trust for the Holders of the Notes of an amount of funds or obligations issued
or guaranteed by the United States of America sufficient to pay and discharge
upon the Stated Maturity thereof the entire indebtedness evidenced by the Notes,
all as provided in the Indenture.

     

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

     

    12.     Amendments, Supplements, and
Waivers.  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 Notes at any time by
the Company and the Trustee with the consent of a majority in aggregate
Outstanding principal amount of the Notes.  The Indenture also
contains provisions permitting the Holders of specified percentages in aggregate
Outstanding principal amount of the Notes 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 or Notes issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not a notation of such consent or waiver is made upon this Note.

     

    Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency or make any other change that does not adversely affect in any
material respect the rights of any Holder of a Note.

     

    13.     Restrictive
Covenants.  The Indenture imposes certain limitations on the
ability of the Company to, among other things, incur additional Indebtedness,
create Liens, merge or consolidate with or into any other Person or sell, lease,
convey or otherwise dispose of all or substantially all of its
assets.  Such limitations are subject to a number of qualifications
and exceptions and, in certain instances upon the occurrence of certain events,
cease to be binding upon the Company.  The Company shall report on an
annual basis to the Trustee on compliance with all conditions and covenants of
the Indenture.

     

    14.   
Successor.  When a
successor Corporation assumes, in accordance with the Indenture, all the
obligations of its predecessor under the Notes and the Indenture, and
immediately before and thereafter no Default exists and certain other conditions
are satisfied, the predecessor Corporation shall be released from those
obligations.

     

    15.     Defaults and
Remedies.  In case an Event of Default with respect to the
Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the
Indenture.

     

    16.     Trustee Dealings with
Company.  The Trustee under the Indenture, in its individual or
any other capacity, may make loans to, accept deposits from and perform services
for the

    Company,
and may otherwise deal with the Company, its Subsidiaries or their respective
Affiliates as if it were not the Trustee.

     

    17.     No Recourse Against
Others.  This Note and all documents, agreements,
understandings and arrangements relating to any transaction contemplated hereby
or thereby have been executed or entered into by an officer of the Company in
his/her capacity as an officer of the Company which has been formed as a
Tennessee corporation, and not individually, and neither the trustees,
directors, officers, employees or shareholders of the Company shall be bound or
have any personal liability hereunder or thereunder.  Each party
hereto shall look solely to the assets of the Company for satisfaction of any
liability of the Company in respect of this Note and all documents, agreements,
understandings and arrangements relating to any transaction contemplated hereby
or thereby and shall not seek recourse or commence any action against any of the
trustees, directors, officers, employees or shareholders of the Company, or any
of their personal assets, for the performance or payment of any obligation
hereunder or thereunder.  By accepting a Note, each Holder shall waive
and release all such liability.  The waiver and release shall be part
of the consideration for the issue of the Notes. The foregoing shall also apply
to any future documents, agreements, understandings, arrangements and
transactions between the parties hereto.

     

    18.     Authentication.  Unless
the Certificate of Authentication hereon has been executed by the Trustee by
manual signature, this Note shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

     

    19.    Counterparts.  The
parties may sign multiple counterparts of this Note.  Each signed
counterpart shall be deemed an original but all of them together represent one
and the same Note.

     

    20.    Governing
Law.  This Note shall be governed by and construed in
accordance with the laws of the State of New York, as applied to agreements made
and to be performed entirely within the State of New York, without regard to
principles of conflicts of law.  Each of the parties to the Indenture
has agreed to submit to the jurisdiction of the courts of the State of New York
in any action or proceeding arising out of or relating to this
Note.
