                           corporation, as trustee (hereinafter sometimes
                           referred to as the "Trustee") under the Indenture
                           dated as of October 1, 1997, between the Company and

                           herein, all terms used and not defined herein are
                           used as defined in the Indenture.

                  WHEREAS, the Company executed and delivered the Indenture to
the Trustee to provide for the future issuance of its Securities, to be issued
from time to time in series as might be determined by the Company under the

                  WHEREAS, pursuant to the terms of the Indenture, the Company
desires to provide for the establishment of a new series of its Securities to be

and all requirements necessary to make this Tenth Supplemental Indenture a valid

valid obligations of the Company, have been performed and fulfilled, and the
execution and delivery of this Supplemental Indenture and the 6% Notes have been
in all respects duly authorized.

                  NOW, THEREFORE, in consideration of the purchase and
acceptance of the 6% Notes by the holders thereof, and for the purpose of

                                    ARTICLE I

                         General Terms and Conditions of
                                  the 6% Notes

                  SECTION 1.01. (a) There shall be and is hereby authorized a
series of Securities designated the "6% Senior Notes Due November 1, 2006",
initially limited in aggregate principal amount to $750,000,000. Without the
consent of the Holders of the Notes, the aggregate principal amount of the 6%
Notes may be increased in the future, on the same terms and conditions and with
the same CUSIP number as the 6% Notes have. The 6% Notes shall mature and the
principal thereof shall be due and payable, together with all accrued and unpaid
interest thereon on November 1, 2006.

                                                                               2


                  SECTION 1.02. (a) The 6% Notes shall be initially issued as
Global Securities. Principal and interest on the 6% Notes issued in certificated
form will be payable, the transfer of such 6% Notes will be registrable and such
6% Notes will be exchangeable for 6% Notes bearing identical terms and
provisions at the office or agency of the Company in the Borough of Manhattan,
The City and State of New York provided for that purpose and transfers of the 6%
Notes will also be registrable at any of the Company's other offices or agencies
as the Company may maintain for that purpose; provided, however, that payment of
interest may be made at the option of the Company by check mailed to the
registered holder at such address as shall appear in the Security Register and
that the payment of principal with respect to the 6% Notes will only be made
upon surrender of the 6% Notes to the Trustee.

                  SECTION 1.03. Each 6% Note will bear interest at the rate of
6% per annum from October 26, 2001 until the principal thereof becomes due and
payable, payable (subject to the provisions of Article II) semi-annually in
arrears on May 1 and November 1 of each year (each, an "Interest Payment Date",
commencing on May 1, 2002), to the person in whose name such 6% Note (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest installment, which, except as set forth
below, shall be, April 15 or October 15 next preceding the Interest Payment Date
with respect to such interest installment. Any installment of interest not
punctually paid or duly provided for shall forthwith cease to be payable to the
registered holder of a 6% Note on such Regular Record Date and may be paid to
the person in whose name such 6% Note (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date to be fixed by the
Trustee for the payment of such defaulted interest, notice whereof to be given
to the registered holders of the 6% Notes not less than 10 days prior to such
Special Record Date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the 6%
Notes may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture.

                  The amount of interest payable for any period will be computed
on the basis of a 360-day year consisting of twelve 30-day months. In the event
that any date on which interest is payable on the 6% Notes is not a Business
Day, then payment of interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay).

                  SECTION 1.04. The 6% Notes are not entitled to any sinking
fund.

                  SECTION 1.05. Section 101 of the Indenture is hereby amended,
solely with respect to the 6% Notes, by amending and restating the definition of
"Principal Property" as follows: "Principal Property" means any radio
broadcasting, television broadcasting, outdoor advertising or live entertainment
property located in the United States owned or leased by the Company or any
Subsidiary, unless, in the opinion of the Board of Directors of the Company,
such properties are not in the aggregate of material importance to the total
business conducted by the Company and its Subsidiaries as an entirety.

defined below) plus 35 basis points plus, in either case, any interest accrued
but not paid to the date of redemption. Notice of any redemption will be mailed
at least 30 days but no more than 60 days before the redemption date to each
holder of the 6% Notes to be redeemed. Unless the Company defaults in payment of
the redemption price, on and after the redemption date interest will cease to

adjusted to constant maturity under the caption "Treasury Constant Maturities,"

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

annum equal to the semi-annual equivalent yield maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue

                  "Comparable Treasury Issue" means the United States Treasury
security selected by an "Independent Investment Banker" as having a maturity

maturity to the remaining term of such 6% Notes.

                  "Independent Investment Banker" means one of the Reference
Treasury Dealers appointed by the Company after consultation with the Trustee.

office or agency, in like coin or currency, at the rate per annum specified in
the title hereof, from May 1 or November 1, as the case may be, next preceding
the date of this Note to which interest on the Notes has been paid or duly
provided for (unless the date hereof is the date to which interest on the Notes
has been paid or duly provided for, in which case from the date of this Note),
or if no interest has been paid on the Notes or duly provided for, from October

Notwithstanding the foregoing, if the date hereof is after the 1st day of any
