                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997
                                  (UNAUDITED)
 
NOTE 1 -- BASIS OF PRESENTATION
 
     Information with respect to the three and nine month periods ended
September 30, 1997 and 1996 is unaudited. The accompanying unaudited
consolidated financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, the unaudited interim consolidated financial
statements contain all adjustments consisting of normal recurring accruals,
considered necessary for a fair presentation. Operating results for the three
and nine month periods ended September 30, 1997, are not necessarily indicative
of the results that may be expected for the year ended December 31, 1997, or for
any other interim period. For further information, refer to the December 31,
1996 consolidated financial statements and footnotes thereto of Capstar
Broadcasting Partners, Inc. and Subsidiaries and GulfStar Communications, Inc.
and Subsidiaries ("Former Gulfstar") included in Capstar Broadcasting Partners,
Inc.'s Amendment No. 1 to Registration Statement on Form S-4 (File No.
333-25683), dated July 8, 1997.
 
     The consolidated financial statements include the accounts of Capstar
Broadcasting Partners, Inc. and its direct and indirect wholly owned
subsidiaries ("Capstar Partners"). The direct wholly-owned subsidiary of the
Company is Capstar Radio Broadcasting Partners, Inc. (formerly named Commodore
Media, Inc.) ("Capstar Radio"). Capstar Broadcasting Corporation ("Capstar
Broadcasting") owns all of the outstanding common stock of Capstar Partners.
 
     On October 16, 1996, Capstar Radio, was acquired pursuant to a merger
agreement dated June 21, 1996 with Capstar Partners, a holding company
controlled by Hicks, Muse, Tate & Furst Equity Fund III, L.P. ("Hicks Muse
Equity, Fund III")
 
     In June 1997, Capstar Broadcasting, a newly formed holding company,
acquired all of the issued and outstanding common stock of Capstar Partners in
exchange for common stock of Capstar Broadcasting.
 
     In July 1997, Capstar Broadcasting acquired Former GulfStar, a company
controlled by the general partner of Hicks Muse Equity Fund III. The acquisition
was effected through a merger of Former GulfStar with and into a newly formed,
wholly owned subsidiary of Capstar Broadcasting, with this subsidiary as the
surviving corporation. Pursuant to the merger agreement, each share of Former
GulfStar's common stock was converted into the right to receive shares of
Capstar Broadcasting, subject to a conversion ratio calculated based on the
relative value of Capstar Broadcasting and Former GulfStar, principally
determined by utilizing projected broadcast cash flows for the year ending
December 31, 1998. Concurrently with the merger: (i) the surviving corporation
was renamed GulfStar Communications, Inc. ("GulfStar"), (ii) Capstar
Broadcasting exchanged its shares of GulfStar for additional shares of Capstar
Partners (iii) Capstar Partners exchanged its shares of GulfStar for additional
shares of Capstar Radio. As a result of the merger and its related transactions,
GulfStar became a wholly owned subsidiary of Capstar Radio. Due to the fact that
Capstar Broadcasting and GulfStar were under common control, the transfer of the
assets and liabilities of GulfStar have been accounted for at historical cost in
a manner similar to a pooling-of-interests except that the acquisition by
Capstar Broadcasting of the minority interest of Former GulfStar has been
accounted for by the purchase method. The accompanying consolidated financial
statements have been restated for all periods presented to give retroactive
effect to the merger and present the financial statements of Gulfstar as the
historical consolidated financial statements of the Company for the period prior
to Capital Partners' Acquisition of Capstar Radio on October 16, 1996, and the
combined consolidated

results of operations for the periods that Capstar Partners and GulfStar
(collectively, the "Company") were under common control. The restated financial
statements also reflect the application of "push down" accounting for the new
basis of accounting for the purchased assets and assumed liabilities in
connection with Capstar Partners' Acquisition of Capstar Radio on October 16,
1996.
 
     The acquisition of Capstar Radio has been accounted for by Capstar Partners
under the purchase method of accounting.
 
NOTE 2 -- RECENT ACCOUNTING PRONOUNCEMENTS
 
     In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128 "Earnings Per
Share" which establishes standards for computing and presenting earnings per
share. SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997.
 
     In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information
About Capital Structure." SFAS No. 129 consolidates the existing disclosure
requirements to disclose certain information about an entity's capital
structure. The statement is effective for financial statements issued for
periods ending after December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
SFAS No. 130 is effective for fiscal years beginning after December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Restated Information," which establishes standards for the way
that public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes standards for related disclosures about
products and services, geographic areas, and major customers. SFAS No. 131 is
effective for financial statements for periods beginning after December 15,
1997.
 
     Management does not believe the implementation of SFAS No. 128, No. 129,
No. 130 and No. 131 will have a material effect on its consolidated financial
statements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the Company, which will mature on February 1, 2009. No interest will accrue on
the Capstar Notes prior to February 1, 2002. Thereafter, interest on the Capstar
Notes will accrue at an annual rate of 12 3/4% and will be payable semi-annually
in cash on February 1 and August 1 each year, commencing on August 1, 2002 to
holders of record on the immediately preceding January 15 and July 15. The
Capstar Notes are redeemable at the option of the Company, in whole or in part,
at any time and from time to time on or after February 1, 2002 at the redemption
prices set forth in the Indenture, plus, without duplication, accrued and unpaid
interest to the redemption date. In addition, prior to February 1, 2001, the
Company, at its option, may use the net cash proceeds of one or more Public
Equity Offerings (as defined in the Indenture) or Major Asset Sales (as defined
in the Indenture) to redeem up to 25% of the aggregate principal amount at
maturity of the Capstar Notes at a redemption price of 112.75%; provided,
however, that after any such redemption, there is outstanding at least 75% of
the original aggregate principal amount at maturity of the Capstar Notes.
 
     On June 17, 1997, Capstar Radio issued (the "Capstar Radio Notes Offering")
$200.0 million in aggregate principal amount of its 9 1/4% Senior Subordinated
Notes due 2007. The proceeds from the issuance of such subordinated notes were

30, 1997. On September 16, 1997, the Company exchanged its 9 1/4% Senior
Subordinated Notes due 2007 (the "1997 Notes"), which were registered under the
Securities Act, for all of the outstanding 9 1/4% Senior Subordinated Notes due
2007 previously issued on June 17, 1997. The terms of the 1997 Notes are
identical in all material respects to the subordinated notes issued on June 17,
1997, except that the 1997 Notes do not bear restrictive legends restricting the
transfer thereof. The 1997 Notes, which mature on July 1, 2007, are general
unsecured obligations of Capstar Radio and rank pari passu in right of payment
to Capstar Radio's 13 1/4% Senior Subordinated Notes due 2003 (the "1995
Notes"). Interest on the 1997 Notes is payable semi-annually on January 1 and
July 1 of each year, commencing on January 1, 1998. The 1997 Notes are
redeemable at the option of Capstar Radio, in whole or in part, on or after July
1, 2002, at the redemption prices set forth in the indenture governing the 1997
Notes, plus accrued and unpaid interest to the date of redemption. In addition,
prior to July 1, 2001, Capstar Radio may, at its option, redeem up to 25% of the
aggregate principal amount of the 1997 Notes originally issued with the net cash
proceeds of one or more Public Equity Offerings or Major Asset Sales (both as
defined in the indenture governing the 1997 Notes), at the redemption prices set
forth in the indenture; provided, however, that after any such redemption there
is outstanding at least 75% of the aggregate principal amount of the 1997 Notes
originally issued.
 
     On February 20, 1997, the Company and Capstar Radio, as borrower, entered
into a credit facility (the "Former Credit Facility") with various banks and
Bankers Trust Company, as administrative agent, which consisted of a $50.0
million revolving loan facility. On August 12, 1997, the Company amended and
restated the Former Credit Facility (the "Credit Facility"). The Credit Facility
consists of a $200.0 million revolving loan facility, and an additional $150
million of multiple advancing term loans subject to future commitment
availability from the banks party to the Credit Facility. $75.0 million of the
revolving loan facility is available to Capstar Radio for the issuance of
letters of credit. Indebtedness under the Credit Facility is collateralized by
the grant of a first priority perfected pledge of Capstar Radio's assets,
including, without limitation, the capital stock of its subsidiaries. The
Company, Capstar Broadcasting and all of the direct and indirect subsidiaries of
the Company (other than Capstar Radio) have guaranteed the Credit Facility,
which guarantees have been collateralized by grants of a first priority
perfected pledge of substantially all of their assets, including Capstar
Broadcasting's pledge of capital stock of the Company and the Company's pledge
of the capital stock of Capstar Radio. Borrowings under the Credit Facility bear
interest at floating rates and require interest payments on varying dates
depending on the interest rate option selected by Capstar Radio. All loans
outstanding under the Credit Facility will mature in 2004. As of November 12,
1997, a principal balance of $72.2 million (excluding $19.9 million of
outstanding letters of credit) was

of Osborn, the Company repaid its outstanding loan balance (including principal
and interest) under the senior credit facility (the "AT&T Credit Facility") of
Capstar Radio with AT&T Commercial Finance Corporation and recognized an
extraordinary loss of approximately $868,000 as a result of the write off of
unamortized deferred financing costs plus a prepayment penalty. In July 1997 and
in connection with the GulfStar merger, the Company recorded an extraordinary
loss on early extinguishment of certain GulfStar debt of approximately $1.4
million.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.
 
     The following discussion of the consolidated financial condition and
results of operations of the Company should be read in conjunction with the
consolidated financial statements and related notes thereto. The following
discussion contains certain forward-looking statements that reflect the
Company's current views with respect to future events and financial performance
and involve risks and uncertainties. The words "anticipate," "believe,"
"expect," "plan," "intend," "estimate," "project," "will," "could," "may" and
similar expressions are intended to identify forward looking statements. The
Company's actual results could differ materially and adversely from those
discussed herein. Factors that could cause or contribute to such differences
include, but are not limited to, risks and uncertainties relating to leverage,
the need for additional funds, consummation of the pending acquisitions,
integration of the recently completed acquisitions, the ability of the Company
to achieve certain cost savings, the ability of the Company to compete
effectively, the management of growth, the introduction of new technology,
changes in the regulatory environment, the popularity of radio as a broadcasting
and advertising medium and changing consumer tastes. The Company undertakes no
obligation to publicly release the results of any revisions to these
forward-looking statements that may be made to reflect any future events or
circumstances.
 
THE COMPANY
 
     As of September 30, 1997, the Company currently owns and operates, provides
programming to or sells advertising on behalf of 165 radio stations located in
43 markets. This represents growth from June 3, 1997 of 95 radio stations and 25
markets. Following completion of the pending acquisitions and the pending
dispositions, the Company will own and operate, provide programming to or sell
advertising on behalf of 245 radio stations located in 61 markets.
 
     The performance of a radio station group, such as the Company, is
customarily measured by its ability to generate Broadcast Cash Flow. "Broadcast
Cash Flow" is defined as operating income before corporate expenses, noncash
compensation expense and depreciation and amortization. Although Broadcast Cash
Flow is not a measure of performance calculated in accordance with generally
accepted accounting principles ("GAAP"), the Company believes that Broadcast
Cash Flow is accepted by the broadcasting industry as a generally recognized
measure of performance and is used by analysts who report publicly on the
performance of broadcasting companies. Nevertheless, this measure should not be
considered in isolation or as a substitute for operating income, net income, net
cash provided by operating activities or any other measure for determining the
Company's operating performance or liquidity which is calculated in accordance
with GAAP.
 
     The primary source of the Company's revenue is the sale of advertising time
on its radio stations. The Company's most significant station operating expenses
are employee salaries and commissions, programming expenses and advertising and
promotional expenditures. The Company strives to control these expenses by
working closely with local station management.
 
     The Company's revenues are primarily affected by the advertising rates its
radio stations can obtain in the face of competition from radio and other media.
The Company's advertising rates are in large part based on a station's ability
to attract audiences in the demographic groups targeted by its advertisers, as
measured principally by Arbitron (an independent rating service) on a quarterly
basis. Because audience ratings in local markets are crucial to a station's
financial success, the Company endeavors to develop strong listener loyalty. The
Company believes that the diversification of formats on its stations helps to
insulate it from the effects of changes in the musical tastes of the public in
any particular format. The number of advertisements that can be broadcast
without jeopardizing listening levels (and the resulting ratings) is limited in
part by the format of a particular station. The Company's stations strive to
maximize revenue by constantly managing the number of commercials available for
sale and adjusting prices based upon local competitive conditions. In the
broadcasting industry, radio stations often utilize trade (or barter) agreements
which exchange advertising time for goods or
 
                                       18
<PAGE>   20
 
services (such as travel or lodging), instead of for cash. The Company seeks to
minimize its use of such agreements. The Company's advertising contracts are
generally short-term. Advertising revenue is either from local advertising or
national advertising. To generate national advertising sales, the Company
engages independent advertising sales representatives that specialize in
national sales for each of its stations.
 
     The radio broadcasting industry is highly competitive and the Company's
stations are located in highly competitive markets. The financial results of
each of the Company's stations are dependent to a significant degree upon its
audience ratings and its share of the overall advertising revenue within the
station's geographic market. Each of the Company's stations competes for
audience share and advertising revenue directly with over FM and AM radio
stations, as well as with other media, including newspapers and television,
within their respective markets. The Company's audience ratings and market share
are subject to change, and any adverse change in audience rating and market
share in any particular market could have a material and adverse effect on the
Company's net revenues. Although the Company competes with other radio stations
with comparable programming formats in most of its markets, if another station
in the market were to convert its programming format to a format similar to one
of the Company's radio stations, if a new radio station were to adopt a
competitive format, or if an existing competitor were to strengthen its
operations, the Company's stations could suffer a reduction in ratings or
advertising revenue and could require increased promotional and other expenses.
In addition, certain of the Company's stations compete, and in the future other
stations may compete, with groups of stations in a market operated by a single
operator. As a result of the Telecommunication Act of 1996 (the "Telecom Act")
the radio broadcasting industry has become increasingly consolidated, resulting
in the existence of radio broadcasting companies which are significantly larger,
with greater financial resources, than the Company. Furthermore, the Telecom Act
will permit other radio broadcasting companies to enter the markets in which the
Company operates or may operate in the future. Although the Company believes
that each of its stations is able to compete effectively in its market, there
can be no assurance that any of the Company's stations will be able to maintain
or increase current audience ratings and advertising revenue market share. The
Company's stations also compete with other advertising media such as newspapers,
television, magazines, billboard advertising, transit advertising and direct
mail advertising. Radio broadcasting is also subject to competition from new
media technologies that are being developed or introduced, such as the delivery
of audio programming by cable television systems or the introduction of digital
audio broadcasting. The Company cannot predict the effect, if any, which these
technologies may have on the radio broadcasting industry.
 
     The Company's revenues vary throughout the year. As is typical in the radio
broadcasting industry, the Company's first calendar quarter generally produces
the lowest revenues for the year, and the fourth calendar quarter generally
produces the highest revenues for the year. The Company's radio operating
results in any period may be affected by the incurrence of advertising and
promotion expenses that do not necessarily produce commensurate revenues until
the impact of the advertising and promotion is realized in future periods. The
Company anticipates that the second and third quarters will reflect the highest
revenues from the Company's concert promotion activities.
 
     Because the Company has incurred substantial indebtedness for its
acquisitions for which it has significant debt service requirements, and because
the Company has significant charges for noncash compensation, dividends and
accretion on preferred stock and depreciation and amortization expense related
to the fixed assets and intangibles acquired in its acquisitions, the Company
expects that it will report net losses attributable to common stock for the
foreseeable future, which losses may be greater than those historically
experienced by the Company.
 
RESULTS OF OPERATIONS
 
     The Company's consolidated financial statements tend not to be directly
comparable from period to period due to acquisition and disposition activity.
The major acquisitions in 1997, all of which have
 
                                       19

  Three Months Ended September 30, 1997 Compared to Three Months Ended September
30, 1996
 
     Net Broadcast Revenue. Net broadcast revenue increased $42.6 million or
492.6% to $51.2 million for the three months ended September 30, 1997 from $8.6
million for the three months ended September 30, 1996. Net broadcast revenue
increases are a result of the continuing acquisitions of the Company through
September 30, 1997.
 
     Station Operating Expenses. Station operating expenses increased $28.7
million or 456.4% to $34.9 million for the three months ended September 30, 1997
from $6.3 million for the three months ended September 30, 1996. The increase is
attributable to additional operating expenses as a result of continuing
acquisitions of the Company through September 30, 1997.
 
     Broadcast Cash Flow. As a result of the factors described above, broadcast
cash flow increased approximately $13.9 million or 588.5% to $16.3 million for
the three months ended September 30, 1997 from $2.4 million for the three months
ended September 30, 1996. The broadcast cash flow margin was 31.8% for the three
months ended September 30, 1997 compared to 27.4% for the three months ended
September 30, 1996.
 
     Corporate Expenses. Corporate expenses increased approximately $3.2 million
or 298.4% to approximately $4.3 million for the three months ended September 30,
1997 from approximately $1.1 million for the three months ended September 30,
1996. This increase was primarily due to the corporate offices of the Company
which opened in October 1996 and the additional corporate expense associated
with acquired radio station operations.
 
     Other Operating Expenses. Depreciation and amortization increased $7.3
million to $8.0 million for the three months ended September 30, 1997 from
approximately $640,000 for the three months ended September 30, 1996 primarily
due to the various acquisitions consummated during 1996 and 1997.

     Operating Income. As a result of the factors described above, the Company's
results for the three months ended September 30, 1997 reflected an operating
income of approximately $4.1 million compared to $650,000 for the three months
ended September 30, 1996.
 
     Interest Expense. Interest expense increased approximately $11.1 million or
829.4% to $12.5 million for the three months ended September 30, 1997 from $1.3
million for the three months ended September 30, 1996. The increase is primarily
attributable to additional borrowings under the Company's credit facility to
fund the Company's acquisitions.
 
     Net Loss Attributable to Common Stock. As a result of the factors described
above, net loss attributable to common stock increased approximately $25.8
million to $27.2 million for the three months ended September 30, 1997 from $1.4
million for the three months ended September 30, 1996.
 
     EBITDA. As a result of the factors described above, EBITDA increased
approximately $10.7 million or 831.0% to $12.0 million for the three months
ended September 30, 1997 from $1.3 million for the three months ended September
30, 1996. The EBITDA margin for the three months ended September 30, 1997 was
23.4% compared to 14.9% for the three months ended September 30, 1996.

     Net Broadcast Revenue. Net broadcast revenue increased $95.3 million or
452.5% to $116.4 million for the nine months ended September 30, 1997 from $21.1
million for the nine months ended September 30, 1996. Net broadcast revenue
increases are a result of continuing acquisitions through September 30, 1997.
 
     Station Operating Expenses. Station operating expenses increased $63.0
million or 395.9% to $78.9 million for the nine months ended September 30, 1997
from $15.9 million for the nine months ended September 30, 1996. The increase is
attributable to additional station operating expenses as a result of continuing

     Broadcast Cash Flow. As a result of the factors described above, broadcast
cash flow increased approximately $32.3 million or 626.7% to $37.5 million for
the nine months ended September 30, 1997 from $5.2 million for the nine months
ended September 30, 1996. The broadcast cash flow margin was 32.2% for the nine
months ended September 30, 1997 compared to 24.5% for the nine months ended
September 30, 1996.
 
     Corporate Expenses. Corporate expenses, including noncash stock
compensation, increased approximately $19.2 million or 1,852.8% to approximately
$20.2 million for the nine months ended September 30, 1997 from approximately
$1.0 million for the nine months ended September 30, 1996. This increase was
primarily due to the corporate offices of the Company which opened in October
1996 and the additional corporate expense associated with radio station
operations acquired during 1996 and 1997. During the nine months ended September
30, 1997, the Company recognized approximately $10.8 million of noncash
compensation expense.
 
     Other Operating Expenses. Depreciation and amortization increased $15.4
million to $17.3 million for the nine months ended September 30, 1997 from
approximately $1.9 million for the nine months ended September 30, 1996
primarily due to the various acquisitions consummated during 1996 and 1997.
 
     Operating Income. As a result of the factors described above, the Company's
results for the nine months ended September 30, 1997 reflected an operating loss
of $1,655 compared to an operating income of $2.3 million for the nine months
ended September 30, 1996. The decrease is primarily attributable to the
increased depreciation and amortization expense.
 
     Interest Expense. Interest expense increased approximately $28.6 million or
888.8% to $31.8 million for the nine months ended September 30, 1997 from $3.2
million for the nine months ended September 30, 1996. The increase is primarily
attributable to additional borrowings under the Company's credit facility to
fund the Company's acquisitions.
 
     Net Loss Attributable to Common Stock. As a result of the factors described
above, net loss attributable to common stock increased approximately $47.7
million to $50.2 million for the nine months ended September 30, 1997 from $2.5
million for the nine months ended September 30, 1996.
 
     EBITDA. As a result of the factors described above, EBITDA increased
approximately $13.2 million or 319.1% to $17.3 million for the nine months ended
September 30, 1997 from $4.1 million for the nine months ended September 30,
1996. The EBITDA margin for the nine months ended September 30, 1997 was 14.9%
compared to 19.6% for the nine months ended September 30, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Pursuit of the Company's acquisition strategy has required a significant
portion of the Company's capital resources. See "Item 1. Financial
Statements -- Notes 3 and 4." As a result of the financing of its acquisitions,
the Company has a substantial amount of long-term indebtedness, and for the
foreseeable future, the Company will use a large percentage of its cash to make
payments under the Credit Facility, the Capstar Notes, the 1995 Notes and the
1997 Notes.
 
     In October 1996, the Company assumed the 1995 Notes in connection with the
acquisition of Capstar Radio. The 1995 Notes are limited in aggregate principal
amount to $76.8 million and bear interest at a rate of 13 1/4% per annum, of
which only 7 1/2% is payable in cash up to May 1, 1998. Beginning on May 1,
1998, the 1995 Notes will bear cash interest at a rate of 13 1/4% per annum
until maturity. The 1995 Notes require semi-annual cash interest payments on
each May 1 and November 1 of $2.9 million through May 1, 1998, and $5.2 million
from November 1, 1998, until maturity. On February 20, 1997, the Company issued
the Capstar Notes at a substantial discount to their aggregate principal amount
at maturity of $277.0 million. The Capstar Notes generated gross proceeds of
approximately $150.3 million and pay no cash interest until August 1, 2002.
Accordingly, the carrying value will increase through accretion until August 1,
2002. Thereafter, interest will be payable semi-annually, in cash, on February 1
and August 1 of each year. On June 17, 1997, Capstar Radio issued the 1997
Notes. Interest on the 1997 Notes is payable semi-annually on January 1 and July
1 of each year, commencing on January 1, 1998, at a rate of 9 1/4% per annum.
The 1997 Notes mature on July 1, 2007.

The Company entered into the Credit Facility in August 1997, which provides for,
among other things, borrowings of up to $200.0 million under a revolving credit
facility. Borrowings under the Credit Facility bear interest at floating rates
and require interest payments on varying dates depending on the interest rate
option selected by Capstar Radio. As of November 12, 1997, a principal balance
of $72.2 million (excluding $19.9 million of outstanding letters of credit) was
outstanding under the Credit Facility and approximately $106.7 million would
have been available for borrowing thereunder.
 
     In addition to debt service, the Company's principal liquidity requirements
will be for working capital and general corporate purposes, including capital
expenditures, which are not expected to be material in amount, and to consummate
its pending acquisitions and, as appropriate opportunities arise, to acquire
additional radio stations. The Company intends to fund the aggregate purchase
price for its pending acquisitions with borrowings under the Credit Facility and
a combination of indebtedness of Capstar Broadcasting, Capstar Radio and/or the
Company and/or capital stock of Capstar Broadcasting or its subsidiaries. The
Company anticipates that it will fund the pending acquisitions with
indebtedness, rather than capital stock, to the fullest extent then permitted
under the debt incurrence covenants contained in the indentures governing the
Capstar Notes, the 1995 Notes, the 1997 Notes and the Company's 12% Subordinated
Exchange Debentures due 2009, the Certificate of Designation governing the
Senior Exchangeable Preferred Stock and the Credit Facility. The Company has not
determined the terms of any such indebtedness or capital stock. The Company's
ability to make such borrowings and issue such indebtedness and capital stock
will depend upon many factors, including, but not limited to, the Company's
success in operating and integrating its radio stations and the condition of the
capital markets at the times of consummation of its pending acquisitions. No
assurances can be given that such financings can be consummated on terms
considered to be favorable by management or at all.
 
     Management believes that the proceeds from the commitment by Hicks, Muse,
Tate & Furst Equity Fund III, L.P. ("HM Fund III") and its affiliates to invest
an additional $50.0 million in equity of Capstar Broadcasting (for which Capstar
Broadcasting has committed to issue capital stock in exchange therefor) and cash
from operating activities, together with available revolving credit borrowings
under the Credit Facility, should be sufficient to permit the Company to fund
its operations and meet its obligations under the agreements governing its
existing indebtedness. The Company may require financing for additional future
acquisitions, if any, and there can be no assurance that it would be able to
obtain such financing for on terms considered to be favorable by management.
Management evaluates potential acquisition opportunities on an on-going basis
and has had, and continues to have, preliminary discussions concerning the
purchase of additional stations. The Company expects that in connection with the
financing of future acquisitions, it may consider disposing of stations in its
markets.
 
     Net cash used in operating activities was $3.9 million and $676,000 for the
nine-month periods ended September 30, 1997 and 1996, respectively. Changes in
the Company's net cash provided by operating activities are primarily the result
of the Company's completed acquisitions and station operating agreements entered
into during the periods and their effects on income from operations and working
capital requirements.
 
     Net cash used in investing activities was $409.8 million and $15.6 million
for the nine-month periods ended September 30, 1997 and 1996, respectively. Net
cash provided by financing activities was $415.4 million and $17.2 million for
the nine-month periods ended September 30, 1997 and 1996, respectively. These
cash flows primarily reflect the borrowings, capital contributions and
expenditures for station acquisitions and dispositions and includes the effects
of the acquisition of Capstar Radio in October 1996.
 
EXTRAORDINARY ITEM
 
     In connection with the acquisition of Osborn, the Company repaid the AT&T
Credit Facility. The repayment of the AT&T Credit Facility resulted in an
extraordinary loss of approximately $868,000 as a
 
                                       25

result of the write off of unamortized deferred financing costs plus a
prepayment penalty. In July 1997 and in connection with the GulfStar Merger, the
Company recorded an extraordinary loss on early extinguishment of certain
GulfStar debt of approximately $1.4 million.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128 "Earnings Per
Share" which establishes standards for computing and presenting earnings per
share. SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997.
 
     In February 1997, the FASB issued SFAS No. 129 "Disclosure of Information
About Capital Structure" which establishes disclosure requirements for an
entity's capital structure. SFAS No. 129 is effective for financial statements
issued for periods ending after December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
SFAS No. 130 is effective for fiscal years beginning after December 15, 1997.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Restated Information," which establishes standards for the way
that public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes standards for related disclosures about
products and services, geographic areas, and major customers. SFAS No. 131 is
effective for financial statements for periods beginning after December 15,
1997.
 
     Management does not believe the implementation of SFAS No. 128, No. 129,
No. 130 and No. 131 will have a material effect on its consolidated financial
statements.

ITEM 2. CHANGES IN SECURITIES.
 
     On September 12, 1997, the Company exchanged its 12% Senior Exchangeable
Preferred Stock (the "New Senior Exchangeable Preferred Stock"), which was
registered under the Securities Act of 1933, for all of the outstanding 12%
Senior Exchangeable Preferred Stock previously sold on June 17, 1997 (the
"Original Senior Exchangeable Preferred Stock") in reliance on Section 4(2) of
the Securities Act and the rules and regulations promulgated thereunder. The
terms of the New Senior Exchangeable Preferred Stock are identical in all
material respects to the Original Senior Exchangeable Preferred Stock, except
that the New Senior Exchangeable Preferred Stock does not bear restrictive
legends restricting the transfer of such stock.
