                                 % Note Due 2029


        This Note is one of a duly authorized issue of unsecured debentures,
notes, or other evidences of indebtedness of the Company (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of       , 1999 (herein called the
"Indenture"), duly executed and delivered by the Company to SunTrust Bank,
Nashville, N.A., as Trustee (herein called the "Trustee"), to which Indenture
and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities. The Securities may be issued in one or more series, which different
series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different redemption provisions (if any), may be subject to different
sinking, purchase or analogous funds (if any) and may otherwise vary as provided
in the Indenture. This Note is one of a series designated as the % Notes Due
2029 (the "Notes") of the Company, limited in aggregate principal amount to
$250,000,000.

        In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof may be declared, and upon such
declaration shall become, due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture.

        The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of each series issued under such
Indenture then Outstanding and affected, to add any provisions to, or change in
any manner or eliminate any of the provisions of, such Indenture or modify in
any manner the rights of the Holders of the Securities of each series so
affected; provided that the Company and the Trustee may not, without the consent
of the Holder of each outstanding Security affected thereby, (i) extend the
stated maturity of any Security, or reduce the principal amount thereof or
reduce the rate or extend the time of payment of interest thereon, or reduce any
amount payable on redemption thereof or reduce the principal amount of any
original issue discount security payable upon acceleration or provable in
bankruptcy or impair or affect the right to institute suit for the payment on
any Security when due or (ii) reduce the aforesaid percentage in principal
amount of Securities of any series issued under such Indenture, the consent of
the Holders of which is required for any such




                                        4





modification. It is also provided in the Indenture that, with respect to certain
defaults or Events of Default regarding the Securities of any series, prior to
any declaration accelerating the maturity of such Securities, the Holders of a
majority in aggregate principal amount Outstanding of the Securities of such
series (or, in the case of certain defaults or Events of Default, all or certain
series of the Securities) may on behalf of the Holders of all the Securities of
such series (or, in the case of certain defaults or Events of Default, all or
certain series of the Securities, as the case may be) waive any such past
default or Event of Default and its consequences. The preceding sentence shall
not, however, apply to a default in the payment of the principal of or interest
on any of the Securities. Any such consent or waiver by the Holder of this Note
(unless revoked as provided in the Indenture) shall be conclusive and binding
upon such Holder and upon all future Holders and owners of this Note and any
Notes which may be issued in exchange or substitution herefor or on registration
of transfer hereof, irrespective of whether or not any notation thereof is made
upon this Note or such other Notes.

        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 in
the manner, at the respective times, at the rate and in the coin or currency
herein prescribed.

        The Notes are redeemable as a whole or in part, at the option of the
Company at any time and from time to time, at a redemption price equal to the
greater of (i) 100% of principal amount of such Notes, or (ii) the sum of the
present values of the Remaining Scheduled Payments of the Notes being redeemed,
discounted to the redemption date on a semi-annual basis (assuming a 360-day

        "Remaining Scheduled Payments" means the remaining scheduled payments of
the principal of and interest on each Note to be redeemed that would be due

reduced by the amount of interest accrued thereon to that redemption date.

equivalent yield to maturity (computed as of the second business day immediately

principal amount) equal to the Comparable Treasury Price for the redemption
date.
        "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker that would be used, 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

        o      the average of the bid and asked prices for the Comparable
               Treasury Issue (expressed in each case as a percentage of its
               principal amount) as of the third business day preceding the
               redemption date, as set forth in the daily statistical release
               (or any successor release) published by the Federal Reserve Bank
               of New York and designated "Composite 3:30 p.m. Quotations for
               U.S. Government Securities" or

        o      if that release (or any successor release) is not published or
               does not contain such prices on that business day, (a) the
               average of the Reference Treasury Dealer Quotations for the
               redemption date, after excluding the highest and lowest of such
               Reference Treasury Dealer Quotations, or (b) if the Trustee
               obtains fewer than four such Reference Treasury Dealer
               Quotations, the average of all quotations obtained

        "Independent Investment Banker" means one of the Reference Treasury

        "Reference Treasury Dealer" means each of Salomon Smith Barney Inc. (and
its successors) and four other nationally recognized investment banking firms

Government securities dealer, the Company will substitute another nationally
recognized investment banking firm that is such a 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

York time, on the third business day preceding the redemption date.
