                  This Security is one of a duly authorized issue of Securities
of the Company designated as its 8 3/4% Notes due March 1, 2012 (Securities of
such series being hereinafter called the "Securities"), limited in initial
aggregate principal amount to $ 400,000,000, issued under an Indenture dated as
of April 1, 1998, as supplemented by the First Supplemental Indenture dated as
of July 7, 2000 (hereinafter called the "Indenture"), between the Company (as

supplemental thereto reference is hereby made for a statement of the respective
rights thereunder of the Company, the Trustee and any Holder of the Securities,
and the terms upon which the Securities are, and are to be, authenticated and

Security 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 Security at the times, place and rate, and in the coin and
currency, herein prescribed.

                  Securities will be redeemable in whole or in part, at the
option of the Company at any time prior to maturity, on not less than 30 or more

and (ii) as determined by the Quotation Agent (as defined below), the sum of the
present values of the remaining scheduled payments of principal and interest
(not including any portion of those payments of interest accrued as of the date
of redemption) discounted to the date of redemption on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate (as defined below) plus 50 basis points plus, in each case,
accrued interest to the date of redemption.

                  "Adjusted Treasury Rate" means, with respect to any date of
redemption, the rate per annum equal to the semi-annual equivalent yield to

                  "Comparable Treasury issue" means the United States Treasury
security selected by the Quotation Agent as having a maturity comparable to the
remaining term of the Securities 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 those Securities.

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

                  "Quotation Agent" means J.P. Morgan Securities Inc. or Salomon
Smith Barney Inc. or another Reference Treasury Dealer appointed by the Company.

                  "Reference Treasury Dealer" means (i) each of J.P. Morgan
Securities Inc. and Salomon Smith Barney Inc. 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
Company shall substitute another Primary Treasury Dealer, and (ii) any other
Primary Treasury Dealer selected by the Company.

                  "Reference Treasury Dealer Quotations" means, with respect to
each Reference Treasury Dealer and any date of redemption, 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)

New York City time, on the third Business Day preceding the date of redemption.

                  On and after the Redemption Date, interest will cease to
accrue on the Securities or any portion thereof called for redemption if the
Company has complied with the provisions of the following sentence. On or before
any Redemption Date, the Company shall deposit with a Paying Agent (or the
Trustee) money sufficient to pay the Redemption Price of and accrued interest on
the Securities to be redeemed on such date. If less than all the Securities are
to be redeemed, the Securities to be redeemed shall be selected by the Trustee
by such method as the Trustee shall deem fair and appropriate.

                  As provided in the Indenture and subject to certain
limitations therein set forth, this Security may be registered for transfer on
the Security Register of the Company, upon surrender of this Security for
registration of transfer at the office or agency of the Company in the Place of
Payment, and at such other locations as the Company may from time to time
designate, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or the Holder's attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

without coupons in the denominations of $1,000 and any integral multiple

                                       4

subject to certain limitations therein set forth, Securities are exchangeable
for a like aggregate principal amount of Securities of different authorized
denominations, as requested by the Holder surrendering the same.

                  No service charge will 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.

                  Prior to due presentment for registration of transfer of this
Security, the Company, the Trustee, the Security Registrar, the Paying Agent and
any agent of any one thereof 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 Company, the Trustee, the Security Registrar, the
Paying Agent nor any such agent shall be affected by notice to the contrary.

consent of the registered holders of the Securities, create and issue further
notes ranking equally and ratably with the Securities in all respects (or in all
respects except for the payment of interest accruing prior to the issue date of
such further notes or except for the first payment of interest following the
issue date of such further notes), so that such further notes shall be
consolidated and form a single series with the Securities and shall have the
same terms as to status, redemption or otherwise as the Securities.

                  If an Event of Default, as defined in the Indenture, with
respect to the Securities shall occur, the principal of all the Securities may
be declared due and payable in the manner and with the effect 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 with respect to the Securities and the rights of the
Holders of the Securities under the Indenture at any time by the Company with
the consent of the Holders of not less than a majority in aggregate principal
amount of the Securities at the time Outstanding. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, 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 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 herefor or in lieu hereof whether or not a notation of
such consent or waiver is made upon this Security.

                  No recourse shall be had for the payment of the principal of
or the interest on this Security, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplemental thereto, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.
