</TABLE>

The majority of the growth in the "as-reported" net revenue and operating
expenses for the three and nine months ended September 30, 2000 was due to the
acquisitions of AMFM Inc. ("AMFM") on August 30, 2000, SFX Entertainment, Inc.
("SFX") on August 1, 2000, Donrey Media Group ("Donrey") on September 1, 2000,
Ackerley's South Florida outdoor advertising division ("Ackerley") on January 5,
2000, Jacor Communications, Inc. ("Jacor") in May 1999, and Dame Media, Inc.,
("Dame") and Dauphin OTA, ("Dauphin") in July 1999. In addition, 55 radio
stations and approximately 65,000 outdoor display faces were purchased, in
multiple transactions, during the first nine months of 2000, the effects of
which, individually and in the aggregate, were not material to the Company's
consolidated financial position or results of operations. Corporate expenses
increased 106% for the first nine months of 2000 versus the first nine months of
1999 as a result of the integration of corporate operations of the Company and
the aforementioned acquisitions.

The majority of the increase in "as-reported" depreciation and amortization was
primarily due to the acquisition of the tangible and intangible assets
associated with the above-mentioned business combinations. Interest expense
increased as a result of greater average borrowing levels related to the
aforementioned acquisitions and higher average borrowing rates. During the nine
months ended September 30, 2000, approximately 35% of the Company's debt had a
floating interest rate based on LIBOR. LIBOR rates increased 25% from an average
of 5.18% in the first nine months of 1999 to an average 6.48% during the first
nine months of 2000. This increase in average borrowing rates was partially
offset by the issuance of convertible notes in the fourth quarter of 1999 at
1.5% annual interest. Equity in earnings of nonconsolidated affiliates increased
168% primarily due to the improved operating results from our equity investments
in Mexico, New Zealand and Australia. The majority of the increase in pre-tax
income is due to a one-time gain of $805.2 million included in the three and
nine-month periods ended September 30, 2000, which related to the sale of
stations associated with the governmental directives regarding the AMFM merger.
Income tax expense increased due to the increase in pre-tax income. The
effective tax rate decreased from 55% in the first nine months of 1999 to 49% in
the first nine months of this year resulting from the one-time gain on sale of

<PAGE>   3


stations offset by the increased nondeductible amortization expenses associated
with the aforementioned acquisitions.

The pro Forma presentation referred to above assumes the acquisitions of and/or
mergers with AMFM, SFX, Donrey, Ackerley, Jacor, Dauphin and Dame occurred on
January 1, 1999. Pro Forma net revenue increased due to improved advertising
rates and improved sell-out rates in the radio segment. In addition, increased
advertising rates and other less significant acquisitions within the outdoor
segment contributed to the increase in pro forma net revenue. An increase in
music tour dates within the entertainment segment also contributed to the
increase in pro forma net revenue. Pro Forma operating expenses increased
primarily from the incremental selling costs related to the additional revenues
and expenses associated with the additional music tour dates. The majority of
the increase in pro forma operating income for the three and nine month periods
ended September 30, 2000 was due to improved operations during the period
primarily in the radio and outdoor segments.

LIQUIDITY AND CAPITAL RESOURCES

The major sources of capital for the Company have been cash flow from
operations, advances on its revolving lines of credit, and funds provided by
various stock, convertible and other bond offerings. As of September 30, 2000
and December 31, 1999, the Company had the following debt outstanding:

In addition, the Company had $384.8 million in unrestricted cash and cash
equivalents on hand at September 30, 2000.

On April 27, 2000, shareholders of the Company approved an increase to the
number of the Company's shares of common stock authorized for issuance from 900
million to 1.5 billion in order to have additional shares available for possible
future acquisition or financing transactions, stock splits, stock dividends and
other issuances, or to satisfy requirements for additional reservations of
shares by reason of future transactions which might require increased
reservations. The Company currently has no plans to issue any of the additional
shares of common stock.

On July 21, 2000, the Company filed a Registration Statement on Form S-3
covering a combined $3.0 billion of debt securities, junior subordinated debt
securities, preferred stock, common stock, warrants, stock purchase contracts
and stock purchase units (the "shelf registration statement"). The shelf
registration statement also covers preferred securities that may be issued from
time to time by the Company's three Delaware statutory business trusts and
guarantees of such preferred securities by the Company. In September 2000, the
Company issued $1.5 billion of debt securities registered under the shelf
registration statement, leaving $1.5 billion available for future issuance.

DOMESTIC CREDIT FACILITIES:

The Company has a $1.95 billion revolving credit facility, of which at September
30, 2000, $1.8 billion was outstanding and $135.0 million was available for
future borrowings. The credit facility began reducing on September 30, 2000,
with quarterly repayment of the outstanding principal balance to continue over
the next five years, with the entire balance to be repaid by the last business
day of June 2005. During the first nine months of the year, the Company made
principal payments on this credit facility totaling $3.4 billion and drew down
$4.4 billion.

The Company had a 364-day multi-currency revolving credit facility for $1.0
billion. On August 30, 2000, in conjunction with the closing of a new $3.0
billion credit facility, the Company repaid all outstanding borrowings and
terminated the facility. During the first eight months of the year, the Company
made principal payments on the credit facility totaling $1.4 billion and drew
down $1.0 billion.


<PAGE>   4

The Company entered into a $3.0 billion credit facility on August 30, 2000,
concurrent with the closing of the AMFM merger. $1.5 billion of this facility is
a five-year multi-currency revolving credit facility and $1.5 billion is a
364-day revolving credit facility, which the Company has the option upon
maturity to convert into a term loan with a five-year maturity. At September 30,
2000, the outstanding balance was 127.2 million British pounds, or approximately
$187.7 million, and $2.8 billion was available for future borrowings under the
$3.0 billion credit facility.

INTERNATIONAL CREDIT FACILITY:

The Company has an 88.0 million British pounds, or approximately $129.8 million,
revolving credit facility with a group of international banks. This
international credit facility allows for borrowings in various foreign
currencies, which are used to hedge net assets in those currencies. At September
30, 2000, approximately $26.6 million was available for future borrowings and
$103.2 million was outstanding under this credit facility. This credit facility
converted into a reducing revolving facility on January 10, 2000, with an
initial payment of 12.0 million British pounds made in January 2000. An
additional payment of 12.0 million British pounds is due on January 10, 2001.
The credit facility expires on January 10, 2002. At September 30, 2000, interest
rates varied from 4.50% to 7.85%.

LIQUID YIELD OPTION NOTES:

The Company assumed Liquid Yield Option Notes ("LYONs") as a part of the merger
with Jacor. The Company assumed 4.75% LYONs due 2018 and 5.50% LYONs due 2011
with an aggregated fair value of $490.1 million. Each LYON has a principal
amount at maturity of $1,000 and is convertible, at the option of the holder, at
any time on or prior to maturity, into the Company's common stock at a
conversion rate of 7.227 shares per LYON and 15.522 shares per LYON for the 2018
and 2011 issues, respectively. The LYONs aggregated balance, net of conversions
to common stock, amortization of premium, and accretion of interest, at
September 30, 2000 was $495.4 million.

Company's credit facilities.

On July 3, 2000, the Company completed a debt offering of Euro 650.0 million
6.50% Notes due July 7, 2005. Interest on the notes is payable annually in

targets will be met.

USES OF FUNDS AND CAPITAL RESOURCES

AMFM MERGER

On August 30, 2000, the Company closed the merger with AMFM Inc. ("AMFM").
Pursuant to the terms of the merger agreement, each share of AMFM common stock
was exchanged for 0.94 shares of the Company's common stock. Approximately 205.4
million shares of the Company's stock were issued in the AMFM merger, valuing
the merger, based on average share value at the signing of the merger agreement,
at $15.9 billion plus the assumption of AMFM's outstanding debt of $3.5 billion.
Additionally, the Company assumed options and common stock warrants with a fair
value of 1.3 billion, which are convertible, subject to applicable vesting, into
approximately 25.5 million shares of the Company's common stock. The Company
refinanced $540.0 million of AMFM's long-term debt at the closing of the merger
using the Company's credit facility. This merger has been accounted for as a
purchase with resulting goodwill of approximately $7.1 billion, which is being
amortized over 25 years on a straight-line basis. This purchase price allocation
is preliminary pending completion of appraisals and other fair value analysis of
assets and liabilities. The results of operations of AMFM have been included in
the Company's financial statements beginning August 30, 2000.

SFX MERGER:

On August 1, 2000, the Company consummated its merger with SFX Entertainment,
Inc. ("SFX"). Pursuant to the terms of the merger agreement, each share of SFX
Class A common stock was exchanged for 0.6 shares of the Company's common stock
and each share of SFX Class B common stock was exchanged for one share of the
Company's common stock. Approximately, 39.1 million shares of the Company's
common stock were issued in the SFX merger. Based on average share value at the
signing of the merger agreement, this merger is valued at $2.9 billion plus the
assumption of SFX's outstanding debt of $1.5 billion. Additionally, the Company
assumed all options and warrants with a fair value of $211.8 million, which are
exercisable for approximately 5.6 million shares




<PAGE>   6


of the Company's common stock. The Company refinanced $815.8 million of SFX's
long-term debt at the closing of the merger using the Company's credit facility.
This merger has been accounted for as a purchase with resulting goodwill of
approximately $4.1 billion, which is being amortized over 20 years on a
straight-line basis. This purchase price allocation is preliminary pending
completion of appraisals and other fair value analysis of assets and
liabilities. The results of operations of SFX have been included in the
Company's financial statements beginning August 1, 2000.

A number of lawsuits were filed by holders of SFX Class A common stock alleging,
among other things, that the difference in consideration for the Class A and
Class B shares constituted unfair consideration to the Class B holders and that
the SFX board breached its fiduciary duties and that the Company aided and
abetted the actions of the SFX board. On September 28, 2000, the Company issued
396,943 shares of its common stock, valued at $29.3 million, as settlement of
these lawsuits and has included the value as part of the purchase price.

OUTDOOR ACQUISITION:

On January 5, 2000, the Company closed the acquisition of Ackerley for
approximately $300.2 million in cash. The acquisition adds approximately 3,500
display faces and enhances the Company's position in Florida. On September 1,
2000, the Company purchased Donrey for $381.5 million in cash. The acquisition
adds outdoor assets to domestic markets where the Company operates other media.

STOCK REPURCHASE:

On October 5, 2000, the Board of Directors authorized the repurchase of up to $1
billion of the Company's common stock.

OTHER:

During the first nine months of 2000, in addition to the acquisitions mentioned
above, the Company acquired approximately 10,000 additional outdoor faces in 39
domestic markets and in malls throughout the U.S. and 55,000 additional display
faces in 23 international markets for a total of $773.3 million in cash. The
Company also acquired 55 radio stations in 17 markets for a total of $194.6
million in cash during the first nine months of 2000. In addition, the Company
acquired a software company for $1.5 million in cash, which is developing
broadcasting software.

During the first nine months of 2000, the Company had capital expenditures of
$320.4 million as follows by segment:

                  Other                                 $ 12.2
</TABLE>

Capital expenditures included $114.3 million for one-time expenditures primarily
related to facility consolidations and a one-time capital expenditure in
conjunction with the long-term extension of certain operating contracts.
Construction of new revenue-producing advertising displays totaled $102.0
million.

Future acquisitions of broadcasting stations, outdoor advertising facilities,
other media-related properties and live entertainment venues affected in
connection with the implementation of the Company's acquisition strategy are
expected to be financed from increased borrowings under the existing credit
facilities, additional public equity and debt offerings and cash flow from
operations. The Company believes that cash flow from operations, as well as the
proceeds from securities offerings made from time to time, will be sufficient to
make all required future interest and principal payments on the credit
facilities, senior convertible notes and bonds, and will be sufficient to fund
all anticipated capital expenditures.

The ratio of earnings to fixed charges has been computed on a total enterprise
basis. Earnings represent income from continuing operations before income taxes
less equity in earnings (loss) of nonconsolidated affiliates plus fixed charges.
Fixed charges represent interest, amortization of debt discount and expense, and
the estimated interest portion of rental charges. The Company had no preferred
stock outstanding and paid no dividends thereon for any period presented.
