                                  THE COMPANY
 
    The Company is the largest Spanish language radio broadcasting company in
the United States and currently owns or programs 36 radio stations in 11
markets. The Company's stations are located in nine of the top ten Hispanic
markets in the United States, including Los Angeles, New York, Miami, San
Francisco/San Jose, Chicago, Houston, San Antonio,
McAllen/Brownsville/Harlingen, and Dallas/Fort Worth.
 
    The Company's strategy is to own and program top performing Spanish language
radio stations, principally in the fifteen largest Spanish language radio
markets in the United States. The top fifteen Hispanic markets account for
approximately 21.6 million Hispanics, representing approximately 71.0% of the
total Hispanic population in the United States. The Company currently has the
leading Spanish language radio station, as measured by audience share, in ten of
the eleven markets in which the Company operates. The Company intends to acquire
or develop additional Spanish language radio stations in the leading Hispanic
markets.
 
    The Company frequently evaluates strategic opportunities both within and
outside its existing line of business which closely relate to serving the
Hispanic market, including opportunities outside of the United States. The
Company expects from time to time to pursue additional acquisitions and may
decide to dispose of certain businesses. Such acquisitions or dispositions could
be material.
 
    The following table sets forth certain information regarding the Company's
radio stations owned or programmed as of December 31, 1997:

<PAGE>
    The Company believes Spanish language radio broadcasting has significant
growth potential for the following reasons:
 
    - THE U.S. HISPANIC POPULATION IS GROWING RAPIDLY.  The U.S. Hispanic
      population is expected to grow from an estimated 27.2 million
      (approximately 10.3% of the total United States population) at the end of
      1995 to an estimated 31.4 million (approximately 11.4% of the total United
      States population) by the year 2000. These estimates imply a growth rate
      of approximately three times the expected growth rate for the total United
      States population during the same period.
 
    - THE U.S. HISPANIC POPULATION IS CONCENTRATED IN 15 MARKETS.  Approximately
      71.0%, or approximately 21.6 million, of all U.S. Hispanics live in these
      markets. The U.S. Hispanic population in the top fifteen markets, as a
      percentage of the total population in such markets, has increased from
      approximately 17.0% in 1980 to approximately 26.0% in 1998. The percentage
      concentration of Hispanics in the top fifteen markets is more than twice
      the percentage of Hispanics in the U.S. as a whole. Since 1980, the
      Hispanic population growth has represented approximately 51.1% of the
      total population growth in the top fifteen Hispanic markets.
 
    - U.S. HISPANICS REPRESENT AN ATTRACTIVE CONSUMER MARKET.  Advertisers
      target Hispanics because, on average, they are younger, their households
      are larger in size and they routinely spend a greater percentage of their
      income on many different kinds of goods and services than do non-Hispanic
      households. The Company believes that as a result advertisers have
      substantially increased their use of Spanish media. Total Spanish language
      advertising revenues have increased from approximately $721.5 million in
      1993 to an estimated $1.4 billion in 1997. This represents a compound
      annual growth rate of approximately 18.0%, which is substantially greater
      than the estimated growth rate for total advertising for the comparable
      period.
 
    The Company was incorporated under the laws of the State of Delaware in
1992. The Company's principal executive offices are located at 100 Crescent
Court, Suite 1777, Dallas, Texas 75201 and the telephone number is (214)
855-8882.
 
                              RECENT DEVELOPMENTS
 
    WNWK-FM ACQUISITION.  On December 1, 1997, the Company announced that it
entered into an agreement with Multicultural Radio Broadcasting, Inc. to
exchange WPAT-AM, the Company's AM station serving the New York City market, and
$115.0 million in cash for the assets of WNWK-FM, an FM station also serving the
New York City market (the "WNWK-FM Acquisition"). WNWK-FM broadcasts on 105.9
MHz from a transmitter site located on the Empire State Building. Following the
consummation of the WNWK-FM Acquisition, the Company plans to convert the
station's programming to a Spanish language format. The Company expects the
station to incur operating losses in 1998 associated with the launch of the
station.
 
    The WNWK-FM Acquisition is subject to the approval of the Federal
Communications Commission (the "FCC") and other closing conditions. Application
was made to the FCC on December 2, 1997, seeking the approval of the WNWK-FM
Acquisition. The WNWK-FM Acquisition also is subject to the expiration or early
termination of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1974, as amended (the "HSR Act"). On December 29,
1997, the Company filed the required information and materials with the
Antitrust Division of the United States Department of Justice (the "Antitrust
Division") and the Federal Trade Commission (the "FTC").
 
    THE TICHENOR MERGER.  On February 14, 1997, the Company completed its
acquisition of Tichenor Media System, Inc. ("Tichenor"), a national radio
broadcasting company engaged in the business of acquiring, developing and
programming Spanish language radio stations (the "Tichenor Merger"). At the time
of the Tichenor Merger, Tichenor owned or programmed 20 radio stations in six of
the ten largest Hispanic markets in the United States. Pursuant to the Tichenor
Merger, the former Tichenor shareholders and warrant holders received an
aggregate of 11,379,756 shares of Common Stock. Because of the
 
                                      S-4
<PAGE>
FCC's "cross interest policy" (see "Description of Common Stock" and
"Description of Capital Stock" in the accompanying Prospectuses), Clear Channel
Communications, Inc. (together with its subsidiaries, "Clear Channel"), which
prior to the Tichenor Merger owned approximately 63% of the outstanding Common
Stock, converted all of its shares of Class A Common Stock and common stock of
Tichenor into 14,156,470 shares of Class B Common Stock, which then represented
approximately 32% of all outstanding Common Stock. At the time of the Tichenor
Merger, Tichenor had approximately $72.0 million of long-term debt, which was
subsequently refinanced by the Company. In addition, all of Tichenor's
outstanding shares of 14% Senior Redeemable Cumulative Preferred Stock were
redeemed for approximately $3.4 million.
 
    KSCA OPTION.  On January 2, 1997, the Company acquired an option to purchase
all of the assets used in connection with the operation of KSCA-FM, Glendale,
California (the "KSCA Option"). In connection with the acquisition of the KSCA
Option, the Company entered into the KSCA Time Brokerage Agreement, pursuant to
which the Company began providing programming to KSCA on February 5, 1997 (the
"KSCA Time Brokerage Agreement"). The KSCA Option, which is exercisable only
upon the death of Gene Autry, the indirect principal stockholder of the seller,
had an initial term which expired on December 31, 1997. The KSCA Option is
renewable for additional one-year terms during the lifetime of Mr. Autry upon
payment by the Company of $3.0 million on or before the then scheduled
expiration date of the KSCA Option. On December 29, 1997, the Company renewed
the KSCA Option through December 31, 1998. In addition, on February 4, 1997,
after receiving notice of early termination of the waiting period under the HSR
Act, the Company made an initial payment of $10.0 million in order to continue
the KSCA Option, as required under the option agreement. All such payments will
be credited against the purchase price for the KSCA assets if the KSCA Option is
exercised; in certain circumstances, the seller is obligated to refund to the
Company a portion of the foregoing payments if the sale is not consummated.
 
    The purchase price for the KSCA assets is the greater of (a) $112.5 million
or (b) the sum of (i) $105.0 million, plus (ii) an amount equal to $13,698.63
per day during the term of the KSCA Time Brokerage Agreement, which daily amount
is subject to reduction if the Company is unable to broadcast its programming on
KSCA under the KSCA Time Brokerage Agreement. Consummation of the purchase will
be subject to a number of conditions, including approval by the FCC of the
transfer of the FCC licenses for the station to the Company.

(1) During August 1994, the Company completed three separate business
    acquisitions. Net revenues and net loss, adjusted for interest expense on
    retired debt, relating to these acquisitions from the respective dates of
    acquisition to September 30, 1994, were approximately $5,488,000 and
    $(80,000), respectively.
 
(2) During the year ended September 30, 1995, the Company completed several
    radio station acquisitions. The results of operations for the year ended
    September 30, 1996 reflect a full year of operations of these radio stations
    compared to a partial year in 1995. Consequently, the results of operations
    for the years ended September 30, 1995 and 1996 are not entirely comparable.
 
(3) On February 19, 1997, the Board of Directors of the Company voted to change
    the Company's fiscal year from September 30 to December 31.
 
(4) On February 14, 1997, the Tichenor Merger was completed. The Tichenor Merger
    was accounted for using the purchase method of accounting. The purchase
    price allocation is preliminary and is subject to change upon final
    determination of the value of the assets acquired and liabilities assumed.
    The preliminary purchase price allocation is as follows:

    Intangible assets are comprised primarily of broadcast licenses and
    goodwill, which are being amortized over 40 years.
 
    Included in the statement of operations are Tichenor net revenues and net
    income for the period February 14, 1997 through September 30, 1997, of
    $37,307,911 and $6,849,262, respectively.
 
(5) On August 5, 1996, Clear Channel completed a tender offer and a related
    private purchase of stock from existing stockholders of the Company
    (collectively, the "Tender Offer"). As a result of the Tender Offer, Clear
    Channel owned approximately 63% of the Class A Common Stock of the Company.
    Clear Channel had to dispose of certain shares and convert its remaining
    shares to Class B Non-Voting Common Stock at the date of the Tichenor Merger
    in order to comply with the cross-interest policy of the FCC. The unaudited
    pro forma condensed consolidated statements of operations for the year ended
    December 31, 1996 and the nine months ended September 30, 1997, assume the
    Tender Offer and Tichenor Merger occurred on January 1, 1996. The pro forma
    information does not purport to present the results of operations of the
    Company had the Tender Offer and Tichenor Merger actually occurred on the
    date specified, nor is it necessarily indicative of the results of
    operations that may be achieved in the future. See the Company's Current
    Report on Form 8-K filed December 12, 1997 and incorporated herein by
    reference for such unaudited pro forma condensed consolidated statements,
    including the footnotes thereto, which contain certain assumptions on which
    such statements are based.
 
(6) Effective August 20, 1994, the Company began accounting for its 49.0%
    interest in Viva America Media Group, a Florida general partnership ("Viva
    Media"), on a consolidated basis. Accordingly, Viva Media's results of
    operations are included in the consolidated financial statements for the
    period August 20, 1994 through September 30, 1994, and for each of the years
    ended September 30, 1995 and 1996. The Company acquired the remaining 51.0%
    of Viva Media on September 7, 1995. Prior to August 20, 1994, the results of
    operations of Viva Media were accounted for using the equity method of
    accounting.
 
(7) In connection with the change in control of ownership described in Note 5,
    the Company incurred certain one-time restructuring charges totaling
    approximately $29,011,237 during the quarter ended September 30, 1996. The
    material components of the restructuring charges are $18,803,029 in payments
    to former senior executives relating to employment contract settlements,
    $4,737,000 in broker commissions and transaction costs, $2,500,000 in costs
    relating to the planned closing of duplicate facilities, plus $1,900,000 in
    severance relating to employee terminations resulting from the
    restructuring.
 
(8) The Company's Board of Directors approved a plan to discontinue the
    operations of the radio network owned by Cadena Radio Central ("CRC"),
    effective August 5, 1996. The total loss relating to the discontinued
    operations of CRC for the year ended September 30, 1996, was approximately
    $9,987,537. The results of operations of CRC for prior years have been
    reclassified and are presented as discontinued operations. CRC ceased the
    majority of its operations by December 1996.
 
(9) Data on station operating income excluding corporate expenses, depreciation
    and amortization (commonly referred to as "broadcast cash flow"), although
    not calculated in accordance with generally accepted accounting principles,
    is widely used in the broadcast industry as a measure of a broadcasting
    company's operating performance. Nevertheless, this measure should not be
    considered in isolation or as a substitute for operating income, cash flows
    from operating activities or any other measure of determining the Company's
    operating performance or liquidity, which is calculated in accordance with
    generally accepted accounting principles.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
INTO THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUSES, THE FOLLOWING
RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE
CLASS A COMMON STOCK OFFERED BY THIS PROSPECTUS SUPPLEMENT. THE COMPANY CAUTIONS
THE READER, HOWEVER, THAT THIS LIST OF RISK FACTORS MAY NOT BE EXHAUSTIVE.
 
    CONCENTRATION OF CASH FLOW FROM LOS ANGELES STATIONS.  Broadcast cash flow
generated by the Company's Los Angeles stations accounted for approximately
38.0% of the Company's broadcast cash flow for the nine months ended September
30, 1997. Increased competition for advertising dollars with other radio
stations and communications media in the Los Angeles metropolitan area, both
generally and relative to the broadcasting industry, increased competition from
a new format competitor and other competitive and economic factors could cause a
decline in revenue generated by the Company's Los Angeles stations. A
significant decline in the revenue of the Los Angeles stations could have a
material adverse effect on the Company's overall results of operations and
broadcast cash flow.
 
    CONTROL BY CERTAIN STOCKHOLDERS.
 
        CONTROL BY THE TICHENOR FAMILY.  McHenry T. Tichenor, Jr., the Company's
    Chairman, President and Chief Executive Officer, McHenry T. Tichenor, Sr.,
    the David T. Tichenor Trust, Warren W. Tichenor, William E. Tichenor and
    Jean T. Russell (collectively, the "Tichenor Family") are parties to a
    Voting Agreement with one another, dated as of July 1, 1996 (the "Voting
    Agreement"). As of December 31, 1997, the Tichenor Family had voting control
    over approximately 26.9% of the shares of Class A Common Stock (23.9%
    assuming the completion of the Offering). This enables the Tichenor Family
    to exert significant influence over all matters submitted to the
    stockholders. Such ownership and control by the Tichenor Family could have
    the effect of delaying or preventing a change in control of the Company,
    thereby possibly having the effect of depriving stockholders of the
    opportunity to receive a premium for their shares. Such ownership and
    control could also have the effect of making the Company less attractive to
    a potential acquirer and could result in holders of Class A Common Stock
    receiving less consideration upon a sale of their shares than might
    otherwise be available in the event of a takeover attempt.
 
        RELATIONSHIP BETWEEN THE COMPANY AND CLEAR CHANNEL.  As of December 31,
    1997, Clear Channel owned no shares of Class A Common Stock and thus was not
    entitled to vote in the election of the Company's directors. However, Clear
    Channel owned all of the outstanding shares of the Company's Class B Common
    Stock, which accounted for approximately a 32.1% interest in the Common
    Stock of the Company (29.4% assuming completion of the Offering). As long as
    Clear Channel owns at least 20.0% of the Company's Common Stock, Clear
    Channel will have a class vote on certain matters, including the sale of all
    or substantially all of the assets of the Company, any merger or
    consolidation involving the Company where the stockholders of the Company
    immediately prior to the transaction would not own at least 50.0% of the
    capital stock of the surviving entity, any reclassification, capitalization,
    dissolution, liquidation or winding up of the Company, the issuance of any
    shares of Preferred Stock by the Company, the amendment of the Company's
    Restated Certificate of Incorporation in a manner that adversely affects the
    rights of the holders of Class B Common Stock, the declaration or payment of
    any non-cash dividends on the Company's Common Stock, or any amendment to
    the Company's Certificate of Incorporation concerning the Company's capital
    stock. Furthermore, shares of Class B Common Stock are convertible into
    shares of Class A Common Stock, at the holder's option, subject to any
    necessary governmental consents, including the consent of the FCC. Because
    of the FCC's cross interest policy, which bars a party that holds an
    attributable relationship in one or more radio stations in a market from
    having a "meaningful relationship" with another radio station in that
    market, Clear Channel may not presently convert its shares of Class B Common
    Stock into shares of Class A Common Stock. The provisions of the Class B
    Common Stock could have the effect of delaying or preventing a change in
    control of the Company, thereby possibly
 
                                      S-8
<PAGE>
    having the effect of depriving stockholders of the opportunity to receive a
    premium for their shares. Such provisions could also have the effect of
    making the Company less attractive to a potential acquirer and could result
    in holders of Class A Common Stock receiving less consideration upon a sale
    of their shares than might otherwise be available in the event of a takeover
    attempt. See "Description of Common Stock" and "Description of Capital
    Stock" in the accompanying Prospectuses.
 
        The nature of the respective businesses of the Company and Clear Channel
    gives rise to potential conflicts of interest between the two companies. The
    Company and Clear Channel are each engaged in the radio broadcasting
    business in certain markets, and as a result, they are competing with each
    other for advertising revenues. As of December 12, 1997, Clear Channel owned
    or programmed 170 radio stations in 36 domestic markets, as well as radio
    stations in a number of foreign countries. Clear Channel also owned or
    programmed 18 television stations and was one of the largest domestic
    outdoor advertising companies based on its total inventory of advertising
    display faces. Clear Channel's television and outdoor advertising operations
    may also be deemed to compete with the Company's business. In addition,
    conflicts could arise with respect to transactions involving the purchase or
    sale of radio broadcasting companies, particularly Spanish language radio
    broadcasting companies, the issuance of shares of Common Stock or Preferred
    Stock, or the payment of dividends by the Company.
 
        Although Clear Channel does not currently engage in the domestic Spanish
    language radio broadcasting business, other than through its ownership of
    shares in the Company, circumstances could arise that would cause Clear
    Channel to engage in the domestic Spanish language radio broadcasting
    business. There can be no assurance that Clear Channel will not engage in
    the domestic Spanish language radio broadcasting business. In addition, as
    part of Clear Channel's overall acquisition strategy, Clear Channel may from
    time to time acquire Spanish language radio broadcasting companies
    individually or as part of a larger group and thereafter engage in the
    Spanish language radio broadcasting business. Such activities could directly
    or indirectly compete with the Company's business. In addition, Clear
    Channel may from time to time make international acquisitions of or
    investments in companies engaged in the Spanish language radio broadcasting
    business outside the United States and the Company and Clear Channel may
    compete for such acquisition or investment opportunities. To the extent the
    Company enters new lines of business, it may be deemed to compete directly
    or indirectly with Clear Channel, and the Company and Clear Channel may
    compete in the future with respect to acquisitions and investment
    opportunities in these areas.
 
    GOVERNMENT REGULATION OF RADIO BROADCASTING INDUSTRY.  Pursuant to the
Communications Act of 1934 (the "Communications Act"), the domestic broadcasting
industry is subject to extensive federal regulation which, among other things,
requires approval by the FCC for the issuance, renewal, transfer and assignment
of broadcasting station operating licenses and limits the number of broadcasting
properties the Company may acquire in any market. The Telecommunications Act of
1996 (the "1996 Act") creates significant new opportunities for broadcasting
companies but also creates uncertainties as to how the FCC and the courts will
enforce and interpret the 1996 Act.
 
    The Company's business will continue to be dependent upon acquiring and
maintaining broadcasting licenses issued by the FCC, which are currently issued
for a term of eight years. There can be no assurance that pending or future
renewal applications will be approved, or that renewals will not include
conditions or qualifications that could adversely affect the Company's
operations. Moreover, governmental regulations and policies may change over time
and there can be no assurance that such changes would not have a material
adverse impact upon the Company's business, financial position and results of
operations.
 
    In addition, the FTC and the Antitrust Division have been reviewing media
acquisitions, including radio station acquisitions, to determine whether they
are in compliance with antitrust laws, even in situations in which the
acquisition conforms with the ownership restrictions of the 1996 Act.
 
                                      S-9
<PAGE>
    ANTITRUST MATTERS.  An important element of the Company's growth strategy
involves the acquisition of additional radio stations, most of which are likely
to require preacquisition antitrust review by the FTC and the Antitrust
Division. Following passage of the 1996 Act, the Antitrust Division has become
more aggressive in reviewing proposed acquisitions of radio stations and radio
station networks, particularly in instances where the proposed acquirer already
owns one or more radio stations in a particular market and the acquisition
involves another radio station in the same market. In the past, the Antitrust
Division has obtained consent decrees requiring an acquirer to dispose of at
least one radio station in a particular market where the acquisition otherwise
would have resulted in an undue concentration of market share by the acquirer.
There can be no assurance that the Antitrust Division or the FTC will not seek
to bar the Company from acquiring additional radio stations in a market where
the Company's existing stations already have a significant market share of the
overall radio market or the Spanish language market segment.
 
    FINANCIAL LEVERAGE; PLEDGE OF ASSETS.  After giving effect to the WNWK-FM
Acquisition, as of September 30, 1997, the Company would have had $139.1 million
outstanding under the Credit Agreement dated February 14, 1997, among the
Company, the lenders signatory thereto and The Chase Manhattan Bank, as
Administrative agent (the "Credit Agreement") and would have had $160.9 million
available under the Credit Agreement for future borrowings. Additionally, as of
September 30, 1997, had the KSCA Option been exercisable and had the Company
exercised such option at the then applicable exercise price of $102.5 million
and had the WNWK-FM Acquisition been consummated, the Company would have had
$241.6 million outstanding under the Credit Agreement and would have had $58.4
million available under the Credit Agreement for future borrowings. The Company
has borrowed and expects to continue borrowing to finance acquisitions of radio
stations and for other corporate purposes. Future acquisitions of radio stations
effected in connection with the implementation of the Company's acquisition
strategy are expected to be financed from increased borrowings under the Credit
Agreement, other debt or equity financings and cash flow from operations. See
"--Growth Through Future Acquisitions; Startups; Capital Requirements." There
can be no assurance that the Company will have sufficient cash flow to satisfy
its future debt service requirements, particularly if there is a downturn in the
operating performance of its radio stations or in economic conditions.
 
    Stock and partnership interests of the Company's subsidiaries are pledged to
secure the Company's obligations under the Credit Agreement. The Credit
Agreement contains various financial and operational covenants and other
restrictions with which the Company must comply, including limitations on
capital expenditures and the incurrence of additional indebtedness, prohibitions
on the payment of cash dividends and the redemption or repurchase of capital
stock of the Company and restrictions on the use of borrowings. The Credit
Agreement may adversely affect the Company's ability to pursue its strategy of
further growth through acquisitions.
 
    GROWTH THROUGH FUTURE ACQUISITIONS; STARTUPS; CAPITAL REQUIREMENTS.  One of
the Company's growth strategies is to acquire additional radio stations. There
can be no assurance that the Company will be able to complete any further
acquisitions or, if completed, that such acquired radio stations can be operated
profitably or assimilated into the Company's business structure in the manner
desired by the Company's management. Entities acquired by the Company may have
liabilities for which the Company may become responsible. Additional debt or
equity financings may be required in order to complete future acquisitions, and
there can be no assurance that the Company will be able to obtain such
financings.
 
    The Company may acquire stations which have not previously broadcast Spanish
language programming. In converting these stations to a Spanish language format,
revenue and cash flow from station operations generated prior to the conversion
may not be indicative of future financial performance. Furthermore, such
conversions may result in significant operating losses for an undetermined
period of time. See "Recent Developments" in the Prospectus Supplement Summary
for a discussion of the WNWK-FM Acquisition, the Company's plan to convert
WNWK-FM's programming to a Spanish language format, and the Company's
expectation that WNWK-FM will incur operating losses during 1998.

    NEW TECHNOLOGIES.  The FCC is considering ways to introduce new technologies
to the radio broadcasting industry, including terrestrial delivery of digital
audio broadcasting on both the AM and FM bands. In 1997, the FCC granted two
licenses for national, satellite-delivered digital audio broadcasting services.
These services will be capable of delivering multiple, high-quality channels of
audio. The Company is unable to predict the effect any such new technology will
have on the Company's financial condition or results of operations. In addition,
cable television operators and direct satellite broadcast television companies
market service commonly referred to as "cable radio" which provides their
subscribers with several high-quality channels of music, news and other
information. Technical considerations currently limit this technology to fixed
locations.
 
    COMPETITION.  Broadcasting is a highly competitive business. The Company's
radio stations compete for audiences and advertising revenues with other radio
stations of all formats, as well as with other media, such as newspapers,
magazines, television, cable television, outdoor advertising and direct mail,
within their respective markets. Audience ratings and market shares are subject
to change and any adverse change in a particular market would have a material
adverse effect on the revenue of stations located in that market. Future
operations are further subject to many variables which could have an adverse
effect upon the Company's financial performance. These variables include
economic conditions, both general and relative to the broadcasting industry;
shifts in population and other demographics; the level of competition for
advertising dollars with other radio stations and other entertainment and
communications media; fluctuations in operating costs; technological changes and
innovations; changes in labor conditions; and changes in governmental
regulations and policies and actions of federal regulatory bodies, including the
FCC, the FTC, and the Antitrust Division. Although the Company believes that
each of its stations is or will be able to compete effectively in its respective
market, there can be no assurance that any such station will be able to maintain
or increase its current audience ratings and advertising revenues. Radio
stations can quickly change formats. Any radio station could shift its format to
duplicate the format of any of the Company's stations. If a station converted
its programming to a format similar to that of a station owned by the Company,
the ratings and broadcast cash flow of the Company's station could be adversely
affected.
 
    UNCERTAINTY AS TO MARKET PRICE OF THE CLASS A COMMON STOCK.  Because the
market price of the Class A Common Stock is subject to fluctuation, the market
value of the shares of the Class A Common Stock may increase or decrease prior
to and following the consummation of the Offering. There can be no assurance
that, at or after the consummation of the Offering, the shares of the Class A
Common Stock will trade at the prices at which such shares have traded in the
past. The prices at which the Class A Common Stock trades after the consummation
of the Offering may be influenced by many factors, including the liquidity of
the Class A Common Stock, investor perceptions of the Company and the radio
broadcasting industry, the operating results of the Company, the Company's
dividend policy, possible future changes in regulation of the radio broadcasting
industry and general economic and market conditions.
 
    FUTURE SALES OF COMMON STOCK BY CLEAR CHANNEL.  After giving effect to the
Offering, Clear Channel will own approximately 29.4% of the outstanding Common
Stock of the Company (approximately 29.0% if the Underwriters' over-allotment
option is exercised in full). Any sale of shares of Common Stock owned by Clear
Channel could adversely affect the market price for the Common Stock and could
impair the ability of the Company to raise money in the equity markets. In
addition, pursuant to an agreement with the Underwriters in connection with the
Offering, Clear Channel has agreed not to sell any shares of the Company's
Common Stock for 90 days from the closing of the Offering. However, there can be
no assurances that Clear Channel will not sell any of such shares in the future
or that such contractual restrictions will not be waived.
 
    SHARES ELIGIBLE FOR FUTURE SALE.  The 4,700,000 shares of Class A Common
Stock sold in the Offering will be freely tradeable without restriction or
further registration under the Securities Act of 1933, as amended (the
"Securities Act"), unless acquired by "affiliates" (as defined in Rule 144
("Rule 144") promulgated by the Securities and Exchange Commission under the
Securities Act). All of the Company's
 
                                      S-11
<PAGE>
currently outstanding shares of Class A Common Stock not held by affiliates are
freely tradeable without restriction or further registration under the
Securities Act, unless acquired by affiliates. Beginning 90 days after the date
of this Prospectus Supplement, all of the currently outstanding shares of Class
A Common Stock owned by the Selling Stockholders will be eligible for sale in
the public market, although they will remain subject to the volume and other
limitations (other than the one year holding period) of Rule 144. In addition,
beginning 90 days after the date of this Prospectus Supplement, all of the
shares owned by Clear Channel will be eligible for resale in the public market,
although such shares will remain subject to the volume and other limitations
(other than the one year holding period) of Rule 144.
 
    DILUTION.  Persons purchasing shares of Class A Common Stock at the offering
price will incur immediate dilution in net tangible book value per share of the
Common Stock. As of September 30, 1997, the deficit in net tangible book value
of the Common Stock was approximately $8.7 million, or $(0.20) per share. The
deficit in net tangible book value per share represents the amount of total
tangible assets of the Company less total liabilities, divided by the number of
shares of Common Stock outstanding. After giving effect to the sale of the
4,000,000 shares of Class A Common Stock offered hereby by the Company, the as
adjusted net tangible book value of the Common Stock at September 30, 1997 would
have been approximately $3.42 per share. This represents an immediate increase
in net tangible book value per share of $3.62 to existing stockholders and an
immediate net tangible book value dilution per share of $41.83 to investors
purchasing shares in the Offering. Net tangible book value dilution per share
represents the difference between the amount per share paid by new investors in
the Offering and the as adjusted tangible book value per share after the
Offering.
 
    UNRELIABILITY OF STATISTICAL DATA.  Statistical data is subject to
interpretation, and statements made herein regarding inferences that the Company
has drawn from such data should not be construed as statements of fact.
Specifically, statistics indicating increased population growth in Hispanic
markets and increased advertising expenditures in such markets do not provide
any assurance that such population growth will continue or that advertising
expenditures in such markets will not decline. In addition, population growth
trends may not correlate with advertising expenditures.
 
    FORWARD-LOOKING STATEMENTS.  This Prospectus Supplement and the
Prospectuses, including the documents incorporated by reference, contain
forward-looking statements within the meaning of Section 27A of the Securities
Act. Discussions containing such forward-looking statements may be found in the
material set forth under "Prospectus Supplement Summary," "Risk Factors" and
"The Company," as well as within the Prospectus Supplement and the Prospectuses
generally. In addition, when used in this Prospectus Supplement or the
Prospectuses, the words "believes," "anticipates," "expects" and similar
expressions are intended to identify forward-looking statements. Such statements
are subject to a number of risks and uncertainties. Actual results in the future
could differ materially from those described in the forward-looking statements
as a result of the risk factors set forth herein and the matters set forth in
the Prospectus Supplement or the Prospectuses generally, including increased
competition, new format competitors, station operating performance, and other
competitive and economic factors. 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.

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of 4,000,000 shares of Class A
Common Stock offered hereby by the Company (after deducting underwriting
discounts and commissions and estimated offering expenses) are estimated to be
approximately $173.3 million ($199.3 million if the Underwriters' over-allotment
option is exercised in full). The Company will use the net proceeds to repay
borrowings outstanding under the Credit Agreement, to finance future
acquisitions and for general corporate purposes. If the WNWK-FM Acquisition is
consummated, a portion of the proceeds of the Offering will be used to repay
amounts borrowed by the Company under the Credit Agreement needed to consummate
such acquisition. The cash portion of the purchase price of the WNWK-FM
Acquisition is $115.0 million. Upon repayment of the Company's borrowings, the
amount repaid will become available to the Company for reborrowing under the
Credit Agreement for general corporate purposes, including working capital and
possible acquisitions of additional broadcast properties. Borrowings under the
Credit Agreement bear interest at a floating rate based on either (i) the London
Interbank Offered Rate ("LIBOR") for deposits in United States dollars, or (ii)
the higher of the agent bank's prime rate plus an incremental rate or the
federal funds rate plus an incremental rate. The average interest rate for
borrowings under the Credit Agreement as of September 30, 1997, was 6.05%. The
committment under the Credit Agreement begins reducing on a quarterly basis on
September 30, 1999, and must be reduced to zero by December 31, 2004. The
Company regularly reviews potential acquisitions of radio stations. The Company
will not receive any of the proceeds from the sale of shares by the Selling
Stockholders.

(1) During August 1994, the Company completed three separate business
    acquisitions. Net revenues and net loss, adjusted for interest expense on
    retired debt, relating to these acquisitions from the respective dates of
    acquisition to September 30, 1994, were approximately $5,488,000 and
    $(80,000), respectively.
 
(2) During the year ended September 30, 1995, the Company completed several
    radio station acquisitions. The results of operations for the year ended
    September 30, 1996 reflect a full year of operations of these radio stations
    compared to a partial year in 1995. Consequently, the results of operations
    for the years ended September 30, 1995 and 1996 are not entirely comparable.
 
(3) On February 19, 1997, the Board of Directors of the Company voted to change
    the Company's fiscal year from September 30 to December 31.
 
(4) On February 14, 1997, the Tichenor Merger was completed. The Tichenor Merger
    was accounted for using the purchase method of accounting. The purchase
    price allocation is preliminary and is subject to change upon final
    determination of the value of the assets acquired and liabilities assumed.
    The preliminary purchase price allocation is as follows:

   Intangible assets are comprised primarily of broadcast licenses and goodwill,
    which are being amortized over 40 years.
 
   Included in the statement of operations are Tichenor net revenues and net
    income for the period February 14, 1997 through September 30, 1997, of
    $37,307,911 and $6,849,262, respectively.
 
(5) On August 5, 1996, Clear Channel completed the Tender Offer. As a result of
    the Tender Offer, Clear Channel owned approximately 63% of the Class A
    Common Stock of the Company. Clear Channel had to dispose of certain shares
    and convert its remaining shares to Class B Non-Voting Common Stock at the
    date of the Tichenor Merger in order to comply with the cross-interest
    policy of the FCC. The unaudited pro forma condensed consolidated statements
    of operations for the year ended December 31, 1996 and the nine months ended
    September 30, 1997, assume the Tender Offer and Tichenor Merger occurred on
    January 1, 1996. The pro forma information does not purport to present the
    results of operations of the Company had the Tender Offer and Tichenor
    Merger actually occurred on the date specified, nor is it necessarily
    indicative of the results of operations that may be achieved in the future.
    See the Company's Current Report on Form 8-K filed December 12, 1997 and
    incorporated herein by reference for such unaudited pro forma condensed
    consolidated statements, including the footnotes thereto, which contain
    certain assumptions on which such statements are based.
 
(6) Effective August 20, 1994, the Company began accounting for its 49.0%
    interest in Viva Media on a consolidated basis. Accordingly, Viva Media's
    results of operations are included in the consolidated financial statements
    for the period August 20, 1994 through September 30, 1994, and for each of
    the years ended September 30, 1995 and 1996. The Company acquired the
    remaining 51.0% of Viva Media September 7, 1995. Prior to August 20, 1994,
    the results of operations of Viva Media were accounted for using the equity
    method of accounting.
 
(7) In connection with the change in control of ownership described in Note 5,
    the Company incurred certain one-time restructuring charges totaling
    approximately $29,011,237 during the quarter ended September 30, 1996. The
    material components of the restructuring charges are $18,803,029 in payments
    to former senior executives relating to employment contract settlements,
    $4,737,000 in broker commissions and transaction costs, $2,500,000 in costs
    relating to the planned closing of duplicate facilities, plus $1,900,000 in
    severance relating to employee terminations resulting from the
    restructuring.
 
(8) The Company's Board of Directors approved a plan to discontinue the
    operations of the radio network owned by CRC, effective August 5, 1996. The
    total loss relating to the discontinued operations of CRC for the year ended
    September 30, 1996, was approximately $9,987,537. The results of operations
    of CRC for prior years have been reclassified and are presented as
    discontinued operations. CRC ceased the majority of its operations by
    December 1996.
 
(9) Data on station operating income excluding corporate expenses, depreciation
    and amortization (commonly referred to as "broadcast cash flow"), although
    not calculated in accordance with generally accepted accounting principles,
    is widely used in the broadcast industry as a measure of a broadcasting
    company's operating performance. Nevertheless, this measure should not be
    considered in isolation or as a substitute for operating income, cash flows
    from operating activities or any other measure of determining the Company's
    operating performance or liquidity, which is calculated in accordance with
    generally accepted accounting principles.

                                  THE COMPANY
 
GENERAL
 
    The Company was incorporated under the laws of the State of Delaware in
1992, as the successor to a radio broadcasting company which began operations in
1974. The Company is the largest Spanish language radio broadcasting company in
the United States and currently owns or programs 36 radio stations in 11
markets. The Company's stations are located in nine of the top ten Hispanic
markets in the United States, including Los Angeles, New York, Miami, San
Francisco/San Jose, Chicago, Houston, San Antonio, McAllen/Brownsville/Harlingen
and Dallas/Fort Worth.
 
    The Company's strategy is to own and program top performing Spanish language
radio stations, principally in the fifteen largest Spanish language radio
markets in the United States. The top fifteen Hispanic markets account for
approximately 21.6 million Hispanics, representing approximately 71% of the
total Hispanic population in the United States. The Company currently has the
leading Spanish language radio station, as measured by audience share, in ten of
the eleven markets in which the Company operates.
 
    The Company intends to acquire or develop additional Spanish language
stations in the leading Hispanic markets. When evaluating a potential
acquisition, the Company considers the following factors: (i) the ability to
generate satisfactory rates of return on its investment, (ii) the ability to
increase operating cash flow at the station, (iii) the strategic importance of
the station to the Company's overall business objectives, (iv) the size and
projected rates of growth of the market's broadcasting revenues, Hispanic
population and consumer spending, and (v) the number of competing stations in
the market.
 
    The Company frequently evaluates strategic opportunities both within and
outside its existing line of business which closely relate to serving the
Hispanic market, including opportunities outside of the United States. The
Company expects from time to time to pursue additional acquisitions and may
decide to dispose of certain businesses. Such acquisitions or dispositions could
be material.
 
HISPANIC MARKET
 
    The Company believes Spanish language radio broadcasting has significant
growth potential for the following reasons:
 
    - THE U.S. HISPANIC POPULATION IS GROWING RAPIDLY.  The U.S. Hispanic
      population is expected to grow from an estimated 27.2 million
      (approximately 10.3% of the total United States population) at the end of
      1995 to an estimated 31.4 million (approximately 11.4% of the total United
      States population) by the year 2000. These estimates imply a growth rate
      of approximately three times the expected growth rate for the total United
      States population during the same period.
 
    - THE U.S. HISPANIC POPULATION IS CONCENTRATED IN 15 MARKETS.  Approximately
      71.0%, or approximately 21.6 million, of all U.S. Hispanics live in these
      markets. The U.S. Hispanic population in the top fifteen markets, as a
      percentage of the total population in such markets, has increased from
      approximately 17.0% in 1980 to approximately 26.0% in 1998. The percentage
      concentration of Hispanics in the top fifteen markets is more than twice
      the percentage of Hispanics in the U.S. as a whole. Since 1980, the
      Hispanic population growth has represented approximately 51.1% of the
      total population growth in the top fifteen Hispanic markets.
 
    - U.S. HISPANICS REPRESENT AN ATTRACTIVE CONSUMER MARKET.  Advertisers
      target Hispanics because, on average, they are younger, their households
      are larger in size and they routinely spend a greater percentage of their
      income on many different kinds of goods and services than do non-Hispanic
      households. The Company believes that as a result advertisers have
      substantially increased their use of Spanish media. Total Spanish language
      advertising revenues have increased from approximately $721.5 million in
      1993 to an estimated $1.4 billion in 1997. This represents a compound
      annual growth rate of approximately 18.0%, which is substantially greater
      than the estimated growth rate for total advertising for the comparable
      period.
 
                                      S-17

PROGRAMMING
 
    Due to differences in origin, Hispanics are not a homogeneous group. The
music, culture, customs and Spanish dialects vary from one radio market to
another. Consequently, the Company programs its stations in a manner responsive
to the local preferences of a target demographic audience in each of the markets
it serves. A well-researched mix of music and on-air programming at an
individual station can attract a wide audience targeted by Spanish language
advertisers. Programming is continuously monitored to maintain its quality and
relevance to the target audience. Most music formats are primarily variations of
Regional Mexican, Tropical, Tejano and Contemporary music styles. The local
program director will select music from the various music styles that best
reflect the music preferences of the local Hispanic audiences. A brief
description of the Company's programming follows:
 
    REGIONAL MEXICAN.  Regional Mexican consists of various types of music
played in different regions of Mexico. Ranchera music, originating in Jalisco,
Mexico, is a traditional folkloric sound commonly referred to as Mariachi music.
Mariachi music features acoustical instruments and is considered the music
indigenous to Mexicans who have lived in the country towns. Nortena means
northern, and is representative of Northern Mexico. Featuring an accordion,
Nortena has a Polka sound with a distinct Mexican flavor. Banda is a regional
format from the state of Sinaloa, Mexico and is popular in California. Banda
resembles up-tempo marching band music with synthesizers. Regional Mexican also
includes Cumbia music, which originates in Colombia.
 
    TROPICAL.  The Tropical format primarily consists of Salsa, Merengue, and
Cumbia music. Salsa is dance music combining Latin Caribbean rhythms with jazz.
Salsa symbolizes music from Puerto Rico, Cuba, and the Dominican Republic and is
popular with Hispanics living in New York, Miami and Chicago. Merengue music is
up-tempo dance music originating in the Dominican Republic.
 
    TEJANO.  Tejano music originated in Texas and is based on Mexican themes but
is indigenous to Texas. It is a combination of contemporary rock, Ranchera, and
country music. The lyrics are primarily sung in Spanish. The on-air talent speak
in Spanish and English.
 
    CONTEMPORARY.  The Contemporary format includes pop, Latin rock, and
ballads. This format is similar to English adult contemporary and contemporary
hit radio stations.
 
    FULL SERVICE.  The Full Service format includes all the traditional radio
services: music, news, sports, traffic reports, special information programs and
weather.
 
    NEWS/TALK.  News includes local, national, international reports and
weather, business, traffic and sports. Talk includes commentary, analysis,
discussion, interviews, call-ins and information shows.

the holder's obligation to purchase the Preferred Stock or Class A Common Stock
under the Stock Purchase Contracts, and the terms of the offering and sale

Trust exists for the sole purposes of (i) issuing the Preferred Securities, (ii)
investing the gross proceeds of the sale of the Preferred Securities in a
specific series of Junior Subordinated Debt Securities, and (iii) engaging in
only those other activities necessary or incidental thereto. All of the Common
Securities will be owned by the Company. The Common Securities will rank pari
passu, and payments will be made thereon pro rata, with the Preferred
Securities, except that upon the occurrence and continuance of an event of
default under the applicable Declaration, the rights of the holders of the
applicable Common Securities to payment in respect of distributions and payments
upon liquidation, redemption and otherwise will be subordinated to the rights of
the holders of the applicable Preferred Securities. The Company will acquire
Common Securities having an aggregate liquidation amount equal to a minimum of
1% of the total capital of each Heftel Trust. Each Heftel Trust will have a term
of at least 20 but not more than 50 years, but may terminate earlier as provided
in the applicable Declaration. Each Heftel Trust's business and affairs will be
conducted by the Trustees. The holder of the Common Securities will be entitled
to appoint, remove or replace any of, or increase or reduce the number of, the
Trustees of each Heftel Trust. The duties and obligations of the Trustees shall
be governed by the Declaration of such Heftel Trust. At least one of the
Trustees of each Heftel Trust will be a person who is an employee or officer of
or who is affiliated with the Company (a "Regular Trustee"). One Trustee of each
Heftel Trust will be a financial institution that is not affiliated with the
Company, which shall act as property trustee and as indenture trustee for the
purposes of the Trust Indenture Act, pursuant to the terms set forth in a
Prospectus Supplement (the "Property Trustee"). In addition, unless the Property
Trustee maintains a principal place of business in the State of Delaware and
otherwise meets the requirements of applicable law, one Trustee of each Heftel
Trust will be a legal entity having a principal place of business in, or an
individual resident of, the State of Delaware (the "Delaware Trustee"). The
Company will pay all fees and expenses related to each Heftel Trust and the
offering of the Preferred Securities. Unless otherwise set forth in the
Prospectus Supplement, the Property Trustee will be The Bank of New York, and
the Delaware Trustee will be The Bank of New York (Delaware). The office of the
Delaware Trustee in the State of Delaware is 100 White Clay Center, Newark,
Delaware 19711. The principal place of business of each Heftel Trust is c/o
Heftel Broadcasting Corporation, 100 Crescent Court, Suite 1777, Dallas, Texas
75201 (telephone: (214) 855-8882).

               RATIO OF EARNINGS TO FIXED CHARGES AND EARNINGS TO
              COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS
 
    The ratios of earnings to fixed charges for the Company are computed by
dividing pretax income from continuing operations after certain adjustments, by
fixed charges. Fixed charges consist of interest expense on all long and
short-term borrowings and the estimated interest portion of rental expense. Set
forth below are the ratios of earnings to fixed charges and earnings to combined
fixed charges and preferred stock dividends (in thousands except ratios).

    Unless otherwise specified in the Prospectus Supplement, the net proceeds
from the sale of the Company Securities offered hereby will be used for general
corporate purposes, including repayment of borrowings, working capital, capital
expenditures, stock repurchase programs and acquisitions. Unless otherwise
specified in the Prospectus Supplement, each Heftel Trust will use all proceeds
received from the sale of Preferred Securities to purchase Junior Subordinated
Debt Securities of the Company. Additional information on the use of net
proceeds from the sale of the Offered Securities offered hereby may be set forth
in the Prospectus Supplement relating to such Offered Securities.
 
                  HOLDING COMPANY STRUCTURE AND SECURED CLAIMS
 
    The Company is a holding company and its assets consist primarily of
investments in its subsidiaries and majority-owned partnerships. The Company's
rights and the rights of its creditors, including holders of Debt Securities or
Junior Subordinated Debt Securities, to participate in the distribution of
assets of any person in which the Company owns an equity interest (including any
subsidiary and majority-owned partnerships) upon such person's liquidation or
reorganization will be subject to prior claims of such person's creditors,
including trade creditors, except to the extent that the Company may itself be a
creditor with recognized claims against such person (in which case the claims of
the Company would still be subject to the prior claims of any secured creditor
of such person and of any holder of indebtedness of such person that is senior
to that held by the Company). Accordingly, the holder of Debt Securities or
Junior Subordinated Debt Securities may be deemed to be effectively subordinated
to such claims and will be subordinated to the secured claims of the Company and
its subsidiaries under the Company's credit facility.
 
    Stock and partnership interests of the Company's subsidiaries are pledged to
secure the Company's obligations under the Credit Agreement dated February 14,
1997, among the Company, the lenders signatory thereto and The Chase Manhattan
Bank., as administrative agent (the "Credit Agreement"). The Credit Agreement
contains various financial and operational covenants and other restrictions with
which the Company must comply, including limitations on capital expenditures and
the incurrence of additional indebtedness, prohibitions on the payment of cash
dividends and the redemption or repurchase of capital stock of the Company and
restrictions on the use of borrowings.

               GENERAL DESCRIPTION OF SECURITIES AND RISK FACTORS
 
    The Company may offer shares of Class A Common Stock, Preferred Stock, Debt
Securities, Junior Subordinated Debt Securities, Warrants, Stock Purchase
Contracts, Stock Purchase Units, or any combination of the foregoing either
individually or as units consisting of one or more Securities under this
Prospectus. Each Heftel Trust may offer Preferred Securities under this
Prospectus.
 
    CERTAIN OF THE SECURITIES TO BE OFFERED HEREBY THEMSELVES MAY INVOLVE A HIGH
DEGREE OF RISK. SUCH RISKS WILL BE SET FORTH IN THE PROSPECTUS SUPPLEMENT
RELATING TO SUCH SECURITY. IN ADDITION, CERTAIN RISK FACTORS, IF ANY, RELATING
TO THE COMPANY'S BUSINESS WILL BE SET FORTH IN A PROSPECTUS SUPPLEMENT.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The following description of the terms of the Debt Securities summarizes
certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of the Debt Securities
and the extent, if any, to which such general provisions may apply to any series
of Debt Securities will be described in the Prospectus Supplement relating to
such series.
 
    Senior Debt Securities may be issued, from time to time, in one or more
series under an Indenture (the "Senior Indenture"), between the Company and The
Bank of New York, as trustee, or such other trustee as shall be named in a
Prospectus Supplement (the "Senior Trustee"). The form of Senior Indenture is
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. Subordinated Debt Securities may be issued, from time to time, in one or
more series under an indenture (the "Subordinated Indenture") between the
Company and The Bank of New York or such other trustee as shall be named in a
Prospectus Supplement (the "Subordinated Trustee"). The form of Subordinated
Indenture is filed as an Exhibit to the Registration Statement of which this
Prospectus is a part. The Senior Indenture and the Subordinated Indenture are
sometimes referred to collectively as the "Indentures," and the Senior Trustee
and the Subordinated Trustee are sometimes referred to collectively as the "Debt
Trustees." None of the Indentures will limit the amount of Debt Securities that
may be issued hereunder, and each Indenture will provide that Debt Securities
may be issued thereunder up to an aggregate principal amount authorized from
time to time by the Company and may be payable in any currency or currency unit
designated by the Company or in amounts determined by reference to an index. The
following statements are subject to the detailed provisions of the Indentures.
Wherever any particular provisions of the Indentures or terms defined therein
are referred to, such provisions and terms are incorporated by reference as a
part of the statements made herein and such statements are qualified in their
entirety by such references, including the definitions therein of certain terms.
Capitalized terms used herein but not defined herein shall have the meanings
ascribed to them in the Indentures.
 
GENERAL
 
    The Senior Debt Securities will be unsecured and will rank equally and
ratably with other unsecured and unsubordinated debt of the Company, unless the
Company shall be required to secure the Senior Debt Securities as described
below under "--Senior Debt Securities." The obligations of the Company pursuant
to any Subordinated Debt Securities will be subordinate in right of payment to
all Senior Indebtedness of the Company with respect to such Subordinated Debt
Securities, and will be described in an accompanying Prospectus Supplement. Debt
Securities will be issued from time to time and offered on terms determined by
market conditions at the time of sale.
 
    The Debt Securities may be issued in one or more series with the same or
various maturities, at par, at a premium, or at a discount. Any Debt Securities
bearing no interest or interest at a rate which at the time of issuance is below
market rates will be sold at a discount (which may be substantial) from their
stated principal amount. Federal income tax consequences and other special
considerations applicable to any
 
                                      A-8
<PAGE>
such substantially discounted Debt Securities will be described in the
Prospectus Supplement relating thereto.
 
    Reference is made to the Prospectus Supplement for the following terms of
the Debt Securities offered hereby: (i) the designation, aggregate principal
amount and authorized denominations of such Debt Securities; (ii) the percentage
of their principal amount at which such Debt Securities will be issued; (iii)
the date or dates on which the Debt Securities will mature (which may be fixed
or extendible); (iv) the rate or rates (which may be fixed or floating) per
annum at which the Debt Securities will bear interest, if any, or the method of
determining such rate or rates; (v) the date or dates on which any such interest
will be payable, the date or dates on which payment of any such interest will
commence and the Regular Record Dates for such Interest Payment Dates; (vi) the
terms of any mandatory or optional redemption (including any provisions for any
sinking, purchase or other analogous fund) or repayment option; (vii) the
currency, currencies or currency units for which the Debt Securities may be
purchased and the currency, currencies or currency units in which the principal
thereof, any premium thereon and any interest thereon may be payable; (viii) if
the currency, currencies or currency units for which the Debt Securities may be
purchased or in which the principal thereof, any premium thereon and any
interest thereon may be payable is at the election of the Company or the
purchaser, the manner in which such election may be made; (ix) if the amount of
payments on the Debt Securities is determined with reference to an index based
on one or more currencies or currency units, changes in the price of one or more
securities or changes in the price of one or more commodities, the manner in
which such amounts may be determined; (x) the extent to which any of the Debt
Securities will be issuable in temporary or permanent global form, or the manner
in which any interest payable on a temporary or permanent Global Security will
be paid; (xi) the terms and conditions upon which the Debt Securities may be
convertible into or exchanged for Class A Common Stock, Preferred Stock, or
indebtedness or other securities of any kind of the Company; (xii) information
with respect to book-entry procedures, if any; (xiii) a discussion of certain
federal income tax, accounting and other special considerations, procedures and
limitations with respect to the Debt Securities; and (xiv) any other specific
terms of the Debt Securities not inconsistent with the applicable Indenture.
 
    If any of the Debt Securities are sold for one or more foreign currencies or
foreign currency units or if the principal of, premium, if any, or any interest
on any series of Debt Securities is payable in one or more foreign currencies or
foreign currency units, the restrictions, elections, federal income tax
consequences, specific terms and other information with respect to such issue of
Debt Securities and such currencies or currency units will be set forth in the
Prospectus Supplement relating thereto.
 
    Unless otherwise specified in the Prospectus Supplement, the principal of,
any premium on, and any interest on the Debt Securities will be payable, and the
Debt Securities will be transferable, at the Corporate Trust Office of the
applicable Debt Trustee in New York, New York, provided that payment of
interest, if any, may be made at the option of the Company by check mailed on or
before the payment date, first class mail, to the address of the person entitled
thereto as it appears on the registry books of the Company or its agent.
 
    Unless otherwise specified in the Prospectus Supplement, the Debt Securities
will be issued only in fully registered form and in denominations of $1,000 and
any integral multiple thereof. No service charge will be made for any transfer
or exchange of any Debt Securities, but the Company may, except in certain
specified cases not involving any transfer, require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.
Unless otherwise set forth in the Prospectus Supplement, interest on outstanding
Debt Securities will be paid to holders of record on the date which is 15 days
immediately prior to the date such interest is to be paid.
 
    The Company's rights and the rights of its creditors (including holders of
Debt Securities) to participate in any distribution of assets of any subsidiary
of the Company upon its liquidation or reorganization or otherwise is
necessarily subject to the prior claims of creditors of the subsidiary, except
to the extent that claims of the Company itself as a creditor of the subsidiary
may be recognized. The
 
                                      A-9
<PAGE>
operations of the Company are conducted through its subsidiaries and, therefore,
the Company is dependent upon the earnings and cash flow of its subsidiaries to
meet its obligations, including obligations under the Debt Securities. The Debt
Securities will be effectively subordinated to all indebtedness of the Company's
subsidiaries.
 
GLOBAL SECURITIES
 
    The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on behalf
of, a depositary (the "Depositary") identified in the Prospectus Supplement
relating to such series. Global Securities may be issued only in fully
registered form and in either temporary or permanent form. Unless and until it
is exchanged in whole or in part for the individual Debt Securities represented
thereby, a Global Security may not be transferred except as a whole by the
Depositary for such Global Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by the Depositary or any nominee of such Depositary to a successor
Depositary or any nominee of such successor.
 
    The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the Prospectus Supplement relating to such
series. The Company anticipates that the following provisions will generally
apply to depositary arrangements.
 
    Upon the issuance of a Global Security, the Depositary for such Global
Security or its nominee will credit, on its book entry registration and transfer
system, the respective principal amounts of the individual Debt Securities
represented by such Global Security to the accounts of persons that have
accounts with such Depositary. Such accounts shall be designated by the dealers,
underwriters or agents with respect to such Debt Securities or by the Company if
such Debt Securities are offered and sold directly by the Company. Ownership of
beneficial interests in a Global Security will be limited to persons that have
accounts with the applicable Depositary ("participants") or persons that may
hold interests through participants. Ownership of beneficial interests in such
Global Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the applicable Depositary or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants). The
laws of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Security.
 
    So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
applicable Indenture. Except as provided below, owners of beneficial interests
in a Global Security will not be entitled to have any of the individual Debt
Securities of the series represented by such Global Security registered in their
names, will not receive or be entitled to receive physical delivery of any such
Debt Securities of such series in definitive form and will not be considered the
owners or holders thereof under the applicable Indenture governing such Debt
Securities.
 
    Payments of principal of, any premium on, and any interest on, individual
Debt Securities represented by a Global Security registered in the name of a
Depositary or its nominee will be made to the Depositary or its nominee, as the
case may be, as the registered owner of the Global Security representing such
Debt Securities. Neither the Company, the applicable Debt Trustee for such Debt
Securities, any Paying Agent, nor the Security Registrar for such Debt
Securities will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Global Security for such Debt Securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
    The Company expects that the Depositary for a series of Debt Securities or
its nominee, upon receipt of any payment of principal, premium or interest in
respect of a permanent Global Security representing
 
                                      A-10
<PAGE>
any of such Debt Securities, immediately will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such Global Security for such Debt Securities as shown
on the records of such Depositary or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in such Global
Security held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name".
Such payments will be the responsibility of such participants.
 
    If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is not
appointed by the Company within 90 days, the Company will issue individual Debt
Securities of such series in exchange for the Global Security representing such
series of Debt Securities. In addition, the Company may at any time and in its
sole discretion, subject to any limitations described in the Prospectus
Supplement relating to such Debt Securities, determine not to have any Debt
Securities of a series represented by one or more Global Securities and, in such
event, will issue individual Debt Securities of such series in exchange for the
Global Security or Securities representing such series of Debt Securities.
Further, if the Company so specifies with respect to the Debt Securities of a
series, an owner of a beneficial interest in a Global Security representing Debt
Securities of such series may, on terms acceptable to the Company, the
applicable Debt Trustee and the Depositary for such Global Security, receive
individual Debt Securities of such series in exchange for such beneficial
interests, subject to any limitations described in the Prospectus Supplement
relating to such Debt Securities. In any such instance, an owner of a beneficial
interest in a Global Security will be entitled to physical delivery of
individual Debt Securities of the series represented by such Global Security
equal in principal amount to such beneficial interest and to have such Debt
Securities registered in its name. Individual Debt Securities of such series so
issued will be issued in denominations, unless otherwise specified by the
Company, of $1,000 and integral multiples thereof.
 
CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
    Each Indenture provides that the Company may not consolidate with or merge
into any other corporation or convey or transfer its properties and assets
substantially as an entirety to any person, unless (i) the successor corporation
shall be a corporation organized and existing under the laws of the United
States or any State thereof or the District of Columbia, and shall expressly
assume by a supplemental indenture the due and punctual payment of the principal
of, any premium on, and any interest on, all the outstanding Debt Securities and
the performance of every covenant in the applicable Indenture on the part of the
Company to be performed or observed; (ii) immediately after giving effect to
such transaction, no Event of Default, and no event which, after notice or lapse
of time or both, would become an Event of Default, shall have happened and be
continuing; and (iii) the Company shall have delivered to the applicable Debt
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, conveyance or transfer and such supplemental
indenture comply with the foregoing provisions relating to such transaction. In
case of any such consolidation, merger, conveyance or transfer, such successor
corporation will succeed to and be substituted for the Company as obligor on the
Debt Securities, with the same effect as if it had been named in the applicable
Indenture as the Company. Other than the restrictions on Mortgages described
below, the Indentures and the Debt Securities do not contain any covenants or
other provisions designed to protect holders of Debt Securities in the event of
a highly leveraged transaction involving the Company or any Subsidiary.
 
EVENTS OF DEFAULT; WAIVER AND NOTICE THEREOF; DEBT SECURITIES IN FOREIGN
  CURRENCIES
 
    As to any series of Debt Securities, an Event of Default is defined in each
Indenture as (i) default for 30 days in payment of any interest on the Debt
Securities of such series, or, in the case of the Subordinated Debt Indenture,
for a period of 90 days; (ii) default in payment of principal of or any premium
on the Debt Securities of such series at maturity; (iii) default in payment of
any sinking or purchase fund or analogous
 
                                      A-11
<PAGE>
obligation, if any, on the Debt Securities of such series; (iv) default by the
Company in the performance of any other covenant or warranty contained in the
applicable Indenture for the benefit of such series which shall not have been
remedied for a period of 90 days after notice is given as specified in the
applicable Indenture; and (v) certain events of bankruptcy, insolvency and
reorganization of the Company.
 
    A default under other indebtedness of the Company will not be a default
under the Indentures and a default under one series of Debt Securities will not
necessarily be a default under another series.
 
    Each Indenture provides that (i) if an Event of Default described in clause
(i), (ii), (iii) or (iv) above (if the Event of Default under clause (iv) is
with respect to less than all series of Debt Securities then outstanding) shall
have occurred and be continuing with respect to any series, either the
applicable Debt Trustee or the holders of not less than 25% in aggregate
principal amount of the Debt Securities of such series then outstanding (each
such series acting as a separate class) may declare the principal (or, in the
case of Original Issue Discount Securities, the portion thereof specified in the
terms thereof) of all outstanding Debt Securities of such series and the
interest accrued thereon, if any, to be due and payable immediately and (ii) if
an Event of Default described in clause (iv) or (v) above (if the Event of
Default under clause (iv) is with respect to all series of Debt Securities then
outstanding) shall have occurred and be continuing, either the applicable Debt
Trustee or the holders of at least 25% in aggregate principal amount of all Debt
Securities then outstanding (treated as one class) may declare the principal
(or, in the case of Original Issue Discount Securities, the portion thereof
specified in the terms thereof) of all Debt Securities then outstanding and the
interest accrued thereon, if any, to be due and payable immediately, but upon
certain conditions such declarations may be annulled and past defaults (except
for defaults in the payment of principal of, any premium on, or any interest on,
such Debt Securities and in compliance with certain covenants) may be waived by
the holders of a majority in aggregate principal amount of the Debt Securities
of such series then outstanding.
 
    Under each Indenture the applicable Debt Trustee must give to the holders of
each series of Debt Securities notice of all uncured defaults known to it with
respect to such series within 90 days after such a default occurs (the term
"default" to include the events specified above without notice or grace periods,
except that in the case of any default of the type described in clause (iv)
above, no such notice shall be given until at least 90 days after the occurrence
thereof); provided that, except in the case of default in the payment of
principal of, any premium on, or any interest on, any of the Debt Securities, or
default in the payment of any sinking or purchase fund installment or analogous
obligations, the applicable Debt Trustee shall be protected in withholding such
notice if it in good faith determines that the withholding of such notice is in
the interests of the holders of the Debt Securities of such series.
 
    No holder of any Debt Securities of any series may institute any action
under either Indenture unless (i) such holder shall have given the Debt Trustee
thereunder written notice of a continuing Event of Default with respect to such
series, (ii) the holders of not less than 25% in aggregate principal amount of
the Debt Securities of such series then outstanding shall have requested the
Debt Trustee thereunder to institute proceedings in respect of such Event of
Default, (iii) such holder or holders shall have offered the Debt Trustee
thereunder such reasonable indemnity as such Debt Trustee may require, (iv) the
Debt Trustee thereunder shall have failed to institute an action for 60 days
thereafter and (v) no inconsistent direction shall have been given to the Debt
Trustee thereunder during such 60-day period by the holders of a majority in
aggregate principal amount of Debt Securities of such series then outstanding.
 
    The holders of a majority in aggregate principal amount of the Debt
Securities of any series affected and then outstanding will have the right,
subject to certain limitations, to direct the time, method and place of
conducting any proceeding for any remedy available to the applicable Debt
Trustee or exercising any trust or power conferred on such Debt Trustee with
respect to such series of Debt Securities. Each Indenture provides that, in case
an Event of Default shall occur and be continuing, the Debt Trustee thereunder,
in exercising its rights and powers under such Indenture, will be required to
use the degree of care of a prudent person in the conduct of such person's own
affairs. Each Indenture further provides that
 
                                      A-12
<PAGE>
the Debt Trustee thereunder shall not be required to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties under such Indenture unless it has reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or
liability is reasonably assured to it.
 
    The Company must furnish to the Debt Trustees within 120 days after the end
of each fiscal year a statement signed by one of certain officers of the Company
to the effect that a review of the activities of the Company during such year
and of its performance under the applicable Indenture and the terms of the Debt
Securities has been made, and, to the best of the knowledge of the signatories
based on such review, the Company has complied with all conditions and covenants
of such Indenture through such year or, if the Company is in default, specifying
such default.
 
    If any Debt Securities are denominated in a coin or currency other than that
of the United States, then for the purposes of determining whether the holders
of the requisite principal amount of Debt Securities have taken any action as
herein described, the principal amount of such Debt Securities shall be deemed
to be that amount of United States dollars that could be obtained for such
principal amount on the basis of the spot rate of exchange into United States
dollars for the currency in which such Debt Securities are denominated (as
evidenced to the applicable Debt Trustee by an Officers' Certificate) as of the
date the taking of such action by the holders of such requisite principal amount
is evidenced to the applicable Debt Trustee as provided in the respective
Indenture.
 
    If any Debt Securities are Original Issue Discount Securities, then for the
purposes of determining whether the holders of the requisite principal amount of
Debt Securities have taken any action herein described, the principal amount of
such Debt Securities shall be deemed to be the portion of such principal amount
that would be due and payable at the time of the taking of such action upon a
declaration of acceleration of maturity thereof.
 
MODIFICATION OF THE INDENTURES
 
    The Indentures provide that the Company and the applicable Debt Trustee may,
without the consent of any holders of Debt Securities, enter into supplemental
indentures for the purposes, among other things, of adding to the Company's
covenants, adding additional Events of Default, establishing the form or terms
of any series of Debt Securities or curing ambiguities or inconsistencies in
such Indenture or making other provisions.
 
    With certain exceptions, the applicable Indenture or the rights of the
holders of the Debt Securities may be modified by the Company and the applicable
Debt Trustee with the consent of the holders of a majority in aggregate
principal amount of the Debt Securities of each series affected by such
modification then outstanding, but no such modification may be made without the
consent of the holder of each outstanding Debt Security affected thereby which
would (i) change the maturity of any payment of principal of, or any premium on,
or any installment of interest on any Debt Security, or reduce the principal
amount thereof or the interest or any premium thereon, or change the method of
computing the amount of principal thereof or interest thereon on any date or
change any place of payment where, or the coin or currency in which, any Debt
Security or any premium or interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the maturity
thereof (or, in the case of redemption or repayment, on or after the redemption
date or the repayment date, as the case may be), (ii) reduce the percentage in
principal amount of the outstanding Debt Securities of any series, the consent
of whose holders is required for any such modification, or the consent of whose
holders is required for any waiver of compliance with certain provisions of the
applicable Indenture or certain defaults thereunder and their consequences
provided for in such Indenture, or (iii) modify any of the provisions of certain
Sections of the applicable Indenture, including the provisions summarized in
this paragraph, except to increase any such percentage or to provide that
certain other provisions of such Indenture cannot be modified or waived without
the consent of the holder of each outstanding Debt Security affected thereby.

SATISFACTION AND DISCHARGE OF THE INDENTURES; DEFEASANCE
 
    The Indentures shall generally cease to be of any further effect with
respect to a series of Debt Securities if (i) the Company has delivered to the
applicable Debt Trustee for cancellation all Debt Securities of such series
(with certain limited exceptions) or (ii) all Debt Securities of such series not
theretofore delivered to the applicable Debt Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within
one year or are to be called for redemption within one year, and the Company
shall have deposited with the applicable Debt Trustee as trust funds the entire
amount sufficient (in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
applicable Debt Trustee) without consideration of any reinvestment and after
payment of all taxes or other charges and assessments in respect thereof payable
by the applicable Debt Trustee to pay at maturity or upon redemption all such
Debt Securities, no default with respect to the Debt Securities has occurred and
is continuing on the date of such deposit, such deposit does not result in a
breach or violation of, or constitute a default under, the applicable Indenture
or any other agreement or instrument to which the Company is a party and the
Company delivered an officers' certificate and an opinion of counsel each
stating that such conditions have been complied with (and if, in either case,
the Company shall also pay or cause to be paid all other sums payable under the
applicable Indenture by the Company).
 
    In addition, the Company shall have a "legal defeasance option" (pursuant to
which it may terminate, with respect to the Debt Securities of a particular
series, all of its obligations under such Debt Securities and the applicable
Indenture with respect to such Debt Securities) and a "covenant defeasance
option" (pursuant to which it may terminate, with respect to the Debt Securities
of a particular series, its obligations with respect to such Debt Securities
under certain specified covenants contained in the applicable Indenture). If the
Company exercises its legal defeasance option with respect to a series of Debt
Securities, payment of such Debt Securities may not be accelerated because of an
Event of Default. If the Company exercises its covenant defeasance option with
respect to a series of Debt Securities, payment of such Debt Securities may not
be accelerated because of an Event of Default related to the specified
covenants.
 
    The Company may exercise its legal defeasance option or its covenant
defeasance option with respect to the Debt Securities of a series only if (i)
the Company irrevocably deposits in trust with the applicable Debt Trustee cash
or U.S. Government Obligations (as defined in the applicable Indenture) for the
payment of principal, premium, if any, and interest with respect to such Debt
Securities to maturity or redemption, as the case may be, (ii) the Company
delivers to the applicable Debt Trustee a certificate from a nationally
recognized firm of independent public accountants expressing their opinion that
the payments of principal and interest when due and without reinvestment on the
deposited U.S. Government Obligations plus any deposited money without
investment will provide cash at such times and in such amounts as will be
sufficient to pay the principal, premium, if any, and interest when due with
respect to all the Debt Securities of such series to maturity or redemption, as
the case may be, (iii) 91 days pass after the deposit is made and during the
91-day period no default described in clause (v) under A--Events of Default,
Waiver and Notice Thereof; Debt Securities in Foreign Currencies" above with
respect to the Company occurs that is continuing at the end of such period, (iv)
no Default has occurred and is continuing on the date of such deposit and after
giving effect thereto, (v) the deposit does not constitute a default under any
other agreement binding on the Company, (vi) the Company delivers to the
applicable Debt Trustee an opinion of counsel to the effect that the trust
resulting from the deposit does not constitute, or is qualified as, a regulated
investment company under the Investment Company Act of 1940, (vii) the Company
shall have delivered to the applicable Debt Trustee an opinion of counsel to the
effect that holders of the Debt Securities will not recognize income, gain or
loss for U.S. federal income tax purposes as a result of such deposit and
defeasance and will be subject to U.S. federal income tax on the same amounts
and in the same manner and at the same times as would have been the case if such
deposit and defeasance had not occurred (and, in the case of legal defeasance
only, such opinion of counsel must be based on a ruling of
 
                                      A-14
<PAGE>
the Internal Revenue Service or other change in applicable U.S. federal income
tax law after the date of the applicable Indenture), and (viii) the Company
delivers to the applicable Debt Trustee an officers' certificate and an opinion
of counsel, each stating that all conditions precedent to the defeasance and
discharge of the Debt Securities of such series as contemplated by the
applicable Indenture have been complied with.
 
    The applicable Debt Trustee shall hold in trust cash or U.S. Government
Obligations deposited with it as described above and shall apply the deposited
cash and the proceeds from deposited U.S. Government Obligations to the payment
of principal, premium, if any, and interest with respect to the Debt Securities
of the defeased series.
 
CONCERNING THE DEBT TRUSTEES
 
    The Debt Trustee for the Senior Debt Securities and the Debt Trustee for the
Subordinated Debt Securities will be identified in the relevant Prospectus
Supplement. In certain instances, the Company or the holders of a majority of
the then outstanding principal amount of the Debt Securities issued under an
indenture may remove the Debt Trustee and appoint a successor Debt Trustee. The
Debt Trustee may become the owner or pledgee of any of the Debt Securities with
the same rights, subject to certain conflict of interest restrictions, it would
have if it were not the Debt Trustee. The Debt Trustee and any successor trustee
must be a corporation organized and doing business as a commercial bank or trust
company under the laws of the United States or of any state thereof, authorized
under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50,000,000 and subject to examination by federal or
state authority. From time to time and subject to applicable law relating to
conflicts of interest, the Debt Trustee may also serve as trustee under other
indentures relating to Debt Securities issued by the Company or affiliated
companies and may engage in commercial transactions with the Company and
affiliated companies. The initial Debt Trustee under each Indenture is The Bank
of New York.
 
CERTAIN COVENANTS
 
    The applicable Prospectus Supplement will describe any material covenants in
respect of any series of Debt Securities.
 
SENIOR DEBT SECURITIES
 
    In addition to the provisions previously described herein and applicable to
all Debt Securities, the following description of the Senior Debt Securities
summarizes certain general terms and provisions of the Senior Debt Securities to
which any Prospectus Supplement may relate. The particular terms of the Senior
Debt Securities offered by any Prospectus Supplement and the extent, if any, to
which such general provisions may apply to any series of Senior Debt Securities
will be described in the Prospectus Supplement relating thereto.
 
    RANKING OF SENIOR DEBT SECURITIES
 
    Unless otherwise specified in a Prospectus Supplement for a particular
series of Debt Securities, all series of Senior Debt Securities will be senior
indebtedness of the Company and will be direct, unsecured obligations of the
Company, ranking on a parity with all other unsecured and unsubordinated
indebtedness of the Company. The Company is a holding company and the Debt
Securities will be effectively subordinated to all existing and future
liabilities, including indebtedness, of the Company's subsidiaries. See "Holding
Company Structure and Secured Claims."
 
SUBORDINATED DEBT SECURITIES
 
    In addition to the provisions previously described herein and applicable to
all Debt Securities, the following description of the Subordinated Debt
Securities summarizes certain general terms and provisions
 
                                      A-15
<PAGE>
of the Subordinated Debt Securities to which any Prospectus Supplement may
relate. The particular terms of the Subordinated Debt Securities offered by any
Prospectus Supplement and the extent, if any, to which such general provisions
may apply to any series of Subordinated Debt Securities will be described in the
Prospectus Supplement relating thereto.
 
    RANKING OF SUBORDINATED DEBT SECURITIES
 
    The Subordinated Debt Securities will be subordinated in right of payment to
certain other indebtedness of the Company to the extent set forth in the
applicable Prospectus Supplement.
 
    The payment of the principal of, premium, if any, and interest on the
Subordinated Debt Securities will be subordinated in right of payment to the
prior payment in full of all Senior Indebtedness of the Company and pari passu
with the Company's trade creditors. No payment on account of principal of,
premium, if any, or interest on the Subordinated Debt Securities and no
acquisition of, or payment on account of any sinking fund for, the Subordinated
Debt Securities may be made unless full payment of amounts then due for
principal, premium, if any, and interest then due on all Senior Indebtedness by
reason of the maturity thereof (by lapse of time, acceleration or otherwise) has
been made or duly provided for in cash or in a manner satisfactory to the
holders of such Senior Indebtedness. In addition, the Subordinated Indenture
provides that if a default has occurred giving the holders of such Senior
Indebtedness the right to accelerate the maturity thereof, or an event has
occurred which, with the giving of notice, or lapse of time, or both, would
constitute such an event of default, then unless and until such event shall have
been cured or waived or shall have ceased to exist, no payment on account of
principal, premium, if any, or interest on the Subordinated Debt Securities and
no acquisition of, or payment on account of a sinking fund for, the Subordinated
Debt Securities may be made. The Company shall give prompt written notice to the
Subordinated Trustee of any default under any Senior Indebtedness or under any
agreement pursuant to which Senior Indebtedness may have been issued. The
Subordinated Indenture provisions described in this paragraph, however, do not
prevent the Company from making a sinking fund payment with Subordinated Debt
Securities acquired prior to the maturity of Senior Indebtedness or, in the case
of default, prior to such default and notice thereof. Upon any distribution of
its assets in connection with any dissolution, liquidation or reorganization of
the Company, all Senior Indebtedness must be paid in full before the holders of
the Subordinated Debt Securities are entitled to any payments whatsoever. As a
result of these subordination provisions, in the event of the Company's
insolvency, holders of the Subordinated Debt Securities may recover ratably less
than senior creditors of the Company. See "Holding Company Structure and Secured
Claims."
 
    For purposes of the description of the Subordinated Debt Securities, the
term "Senior Indebtedness" means the principal of and premium, if any, and
interest on the following, whether outstanding on the date of execution of the
Subordinated Indenture or thereafter incurred or created (i) indebtedness of the
Company for money borrowed by the Company (including purchase money obligations
with an original maturity in excess of one year) or evidenced by securities
(other than the Subordinated Debt Securities or Junior Subordinated Debt
Securities), notes, bankers' acceptances or other corporate debt securities or
similar instruments issued by the Company; (ii) obligations with respect to
letters of credit; (iii) indebtedness of the Company constituting a guarantee of
indebtedness of others of the type referred to in the preceding clauses (i) and
(ii); or (iv) renewals, extensions or refundings of any of the indebtedness
referred to in the preceding clauses (i), (ii) and (iii) unless, in the case of
any particular indebtedness, renewal, extension or refunding, under the express
provisions of the instrument creating or evidencing the same, or pursuant to
which the same is outstanding, such indebtedness or such renewal, extension or
refunding thereof is not superior in right of payment to the Subordinated Debt
Securities.

               DESCRIPTION OF JUNIOR SUBORDINATED DEBT SECURITIES
 
    The following description of the terms of the Junior Subordinated Debt
Securities summarizes certain general terms and provisions of the Junior
Subordinated Debt Securities to which any Prospectus Supplement may relate. The
particular terms of the Junior Subordinated Debt Securities offered by any
Prospectus Supplement and the extent, if any, to which such general provisions
may apply to any series of Junior Subordinated Debt Securities will be described
in the Prospectus Supplement relating thereto.
 
    Junior Subordinated Debt Securities may be issued from time to time in one
or more series under an Indenture (the "Junior Subordinated Indenture") between
the Company and The Bank of New York or such other trustee as may be named in a
Prospectus Supplement (the "Junior Subordinated Indenture Trustee"). The form of
Junior Subordinated Indenture has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. The following description
summarizes the material terms of the Junior Subordinated Indenture and is
qualified in its entirety by reference to the Junior Subordinated Indenture and
the Trust Indenture Act. Whenever particular provisions or defined terms in the
Junior Subordinated Indenture are referred to herein, such provisions or defined
terms are incorporated by reference herein.
 
GENERAL
 
    The Junior Subordinated Debt Securities will be unsecured, junior
subordinated obligations of the Company. The Junior Subordinated Indenture does
not limit the amount of additional indebtedness the Company or any of its
subsidiaries may incur. Since the Company is a holding company, the Company's
rights and the rights of its creditors, including the holders of Junior
Subordinated Debt Securities, to participate in the assets of any subsidiary
upon the latter's liquidation or recapitalization will be subject to the prior
claims of the subsidiary's creditors, except to the extent that the Company may
itself be a creditor with recognized claims against the subsidiary.
 
    The Junior Subordinated Indenture does not limit the aggregate principal
amount of indebtedness which may be issued thereunder and provides that Junior
Subordinated Debt Securities may be issued thereunder from time to time in one
or more series. The Junior Subordinated Debt Securities are issuable in one or
more series pursuant to a board resolution or an indenture supplemental to the
Junior Subordinated Indenture.
 
    In the event Junior Subordinated Debt Securities are issued to a Heftel
Trust or a Trustee of such Heftel Trust in connection with the issuance of
Preferred Securities by such Heftel Trust, such Junior Subordinated Debt
Securities subsequently may be distributed pro rata to the holders of such
Preferred Securities in connection with the dissolution of such Heftel Trust
upon the occurrence of certain events described in the applicable Prospectus
Supplement. Only one series of Junior Subordinated Debt Securities will be
issued to a Heftel Trust or a Trustee of such Heftel Trust in connection with
the issuance of Preferred Securities by such Heftel Trust.
 
    Reference is made to the Prospectus Supplement for the following terms of
the series of Junior Subordinated Debt Securities being offered hereby (to the
extent such terms are applicable to the Junior Subordinated Debt Securities):
(i) the specific designation of such Junior Subordinated Debt Securities,
aggregate principal amount and purchase price; (ii) any limit on the aggregate
principal amount of such Junior Subordinated Debt Securities; (iii) the date or
dates on which the principal of such Junior Subordinated Debt Securities is
payable and the right, if any, to extend such date or dates; (iv) the rate or
rates at which such Junior Subordinated Debt Securities will bear interest or
the method of calculating such rate or rates, if any; (v) the date or dates from
which such interest shall accrue, the interest payment dates on which such
interest will be payable or the manner of determination of such interest payment
dates and the record dates for the determination of holders to whom interest is
payable on any such interest payment dates; (vi) the right, if any, to extend
the interest payment periods and the duration of such extension; (vii) the
period or periods within which, the price or prices at which, and the terms and
 
                                      A-17
<PAGE>
conditions upon which, such Junior Subordinated Debt Securities may be redeemed,
in whole or in part, at the option of the Company; (viii) the obligation, if
any, of the Company to redeem or purchase such Junior Subordinated Debt
Securities pursuant to any sinking fund or analogous provisions or at the option
of the holder thereof and the period or periods within which, the price or
prices at which, and the terms and conditions upon which, such Junior
Subordinated Debt Securities shall be redeemed or purchased, in whole or part,
pursuant to such obligation; (ix) any applicable federal income tax
consequences, including whether and under what circumstances the Company will
pay additional amounts on the Junior Subordinated Debt Securities held by a
person who is not a U.S. person in respect of any tax, assessment or
governmental charge withheld or deducted and, if so, whether the Company will
have the option to redeem such Junior Subordinated Debt Securities rather than
pay such additional amounts; (x) the form of such Junior Subordinated Debt
Securities; (xi) if other than denominations of $25 or any integral multiple
thereof, the denominations in which such Junior Subordinated Debt Securities
shall be issuable; (xii) any and all other terms with respect to such series,
including any modification of or additions to the events of default or covenants
provided for with respect to the Junior Subordinated Debt Securities, and any
terms which may be required by or advisable under applicable laws or regulations
not inconsistent with the Junior Subordinated Indenture; (xiii) the terms and
conditions upon which the Junior Subordinated Debt Securities may be convertible
into or exchanged for Class A Common Stock, Preferred Stock, Preferred
Securities, or indebtedness or other securities of any kind of the Company; and
(xiv) whether such Junior Subordinated Debt Securities are issuable as a global
security, and in such case, the identity of the depositary.
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures will be issued in United States dollars in fully
registered form without coupons in denominations of $25 or integral multiples
thereof. No service charge will be made for any transfer or exchange of any
Junior Subordinated Debt Securities, but the Company may, except in certain
specified cases not involving any transfer, require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.
Unless otherwise set forth in the Prospectus Supplement, interest on outstanding
Junior Subordinated Debt Securities will be paid to holders of record on the
date which is 15 days immediately prior to the date such interest is to be paid.
 
    Junior Subordinated Debt Securities may bear interest at a fixed rate or a
floating rate. Junior Subordinated Debt Securities bearing no interest or
interest at a rate that at the time of issuance is below the prevailing market
rate will be sold at a discount below their stated principal amount. Special
federal income tax considerations applicable to any such discounted Junior
Subordinated Debt Securities or to certain Junior Subordinated Debt Securities
issued at par which are treated as having been issued at a discount for federal
income tax purposes will be described in the applicable Prospectus Supplement.
 
GLOBAL SECURITIES
 
    If any Junior Subordinated Debt Securities of a series are represented by
one or more Global Securities, the applicable Prospectus Supplement will
describe the circumstances, if any, under which beneficial owners of interests
in any such Global Security may exchange such interests for Junior Subordinated
Debt Securities of such series and of like tenor and principal amount in any
authorized form and denomination. Principal of, and any premium and interest on,
a Global Security will be payable in the manner described in the applicable
Prospectus Supplement.
 
    The specific terms of the depositary arrangement with respect to any portion
of a series of Junior Subordinated Debt Securities to be represented by a Global
Security will be described in the applicable Prospectus Supplement.
 
                                      A-18
<PAGE>
CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
    The Junior Subordinated Indenture provides that the Company may not
consolidate with or merge into any other corporation or convey or transfer its
properties and assets substantially as an entirety to any person, unless (i) the
successor corporation shall be a corporation organized and existing under the
laws of the United States or any State thereof or the District of Columbia, and
shall expressly assume by a supplemental indenture the due and punctual payment
of the principal of, any premium on, and any interest on, all the outstanding
Junior Subordinated Debt Securities and the performance of every covenant in the
Junior Subordinated Indenture on the part of the Company to be performed or
observed; (ii) immediately after giving effect to such transaction, no Event of
Default, and no event which, after notice or lapse of time or both, would become
an Event of Default, shall have happened and be continuing; and (iii) the
Company shall have delivered to the applicable Junior Subordinated Indenture
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, conveyance or transfer and such supplemental
indenture comply with the foregoing provisions relating to such transaction. In
case of any such consolidation, merger, conveyance or transfer, such successor
corporation will succeed to and be substituted for the Company as obligor on the
Junior Subordinated Debt Securities, with the same effect as if it had been
named in the Junior Subordinated Indenture as the Company. The Junior
Subordinated Indentures and the Junior Subordinated Debt Securities do not
contain any covenants or other provisions designed to protect holders of Junior
Subordinated Debt Securities in the event of a highly leveraged transaction
involving the Company or any Subsidiary.
 
EVENTS OF DEFAULT; WAIVER AND NOTICE THEREOF; JUNIOR SUBORDINATED DEBT
  SECURITIES IN FOREIGN CURRENCIES
 
    As to any series of Junior Subordinated Debt Securities, an Event of Default
is defined in each Junior Subordinated Indenture as (i) default for 90 days in
payment of any interest on the Junior Subordinated Debt Securities of such
series (subject to the deferral of any due date in the case of an Extension
Period); (ii) default in payment of principal of or any premium on the Junior
Subordinated Debt Securities of such series at maturity; (iii) default in
payment of any sinking or purchase fund or analogous obligation, if any, on the
Junior Subordinated Debt Securities of such series; (iv) default by the Company
in the performance, or breach, of any other covenant or warranty contained in
the Junior Subordinated Indenture for the benefit of such series which shall not
have been remedied for a period of 90 days after notice is given as specified in
the Junior Subordinated Indenture; and (v) certain events of bankruptcy,
insolvency and reorganization of the Company.
 
    A default under other indebtedness of the Company will not be a default
under the Junior Subordinated Indentures and a default under one series of Debt
Securities or Junior Subordinated Debt Securities will not necessarily be a
default under another series.
 
    The Junior Subordinated Indenture provides that (i) if an Event of Default
described in clause (i), (ii), (iii) or (iv) above (if the Event of Default
under clause (iv) above is with respect to less than all series of Junior
Subordinated Debt Securities outstanding) shall have occurred and be continuing
with respect to any series, either the Junior Subordinated Indenture Trustee or
the holders of not less than 25% in aggregate principal amount of the Junior
Subordinated Debt Securities of such series then outstanding (each such series
acting as a separate class) may declare the principal (or, in the case of
Original Issue Discount Securities, the portion thereof specified in the terms
thereof) of all outstanding Junior Subordinated Debt Securities of such series
and the interest accrued thereon, if any, to be due and payable immediately, and
(ii) if an Event of Default described in clause (iv) or (v) above (if the Event
of Default under clause (iv) above is with respect to all series of Junior
Subordinated Debt Securities then outstanding) shall have occurred and be
continuing, either the Junior Subordinated Indenture Trustee or the holders of
at least 25% in aggregate principal amount of all Junior Subordinated Debt
Securities then outstanding (treated as one class) may declare the principal
(or, in the case of Original Issue Discount Securities, the portion thereof
specified in the terms thereof) of all Junior Subordinated Debt Securities
 
                                      A-19
<PAGE>
then outstanding and the interest accrued thereon, if any, to be due and payable
immediately, but upon certain conditions such declarations may be annulled and
past defaults (except for defaults in the payment of principal of, any premium
on, or any interest on, such Junior Subordinated Debt Securities and in
compliance with certain covenants) may be waived by the holders of a majority in
aggregate principal amount of the Junior Subordinated Debt Securities of such
series then outstanding (subject to, in the case of any series of Junior
Subordinated Debt Securities held as trust assets of a Heftel Trust and with
respect to which a Security Exchange has not theretofore occurred, such consent
of the holders of the Preferred Securities and the Common Securities of such
Heftel Trust as may be required under the Declaration of Trust of such Heftel
Trust).
 
    "Security Exchange" when used with respect to the Securities of any series
which are held as trust assets of a Heftel Trust pursuant to the Declaration of
Trust of such Heftel Trust means the distribution of the Securities of such
series by such Heftel Trust in exchange for the Preferred Securities and the
Common Securities of such Heftel Trust in dissolution of such Heftel Trust
pursuant to the Declaration of Trust of such Heftel Trust.
 
    Under the Junior Subordinated Indenture the Junior Subordinated Indenture
Trustee must give to the holders of each series of Junior Subordinated Debt
Securities notice of all uncured defaults known to it with respect to such
series within 90 days after such a default occurs (the term "default" to include
the events specified above without notice or grace periods, except that in the
case of any default of the type described in clause (d) above, no such notice
shall be given until at least 90 days after the occurrence thereof); provided
that, except in the case of default in the payment of principal of, any premium
on, or any interest on, any of the Junior Subordinated Debt Securities, or
default in the payment of any sinking or purchase fund installment or analogous
obligations, the applicable Junior Subordinated Indenture Trustee shall be
protected in withholding such notice if it in good faith determines that the
withholding of such notice is in the interests of the holders of the Junior
Subordinated Debt Securities of such series.
 
    No holder of any Junior Subordinated Debt Securities of any series may
institute any action under the Junior Subordinated Indenture unless (i) such
holder shall have given the Junior Subordinated Indenture Trustee thereunder
written notice of a continuing Event of Default with respect to such series,
(ii) the holders of not less than 25% in aggregate principal amount of the
Junior Subordinated Debt Securities of such series then outstanding shall have
requested the Junior Subordinated Indenture Trustee thereunder to institute
proceedings in respect of such Event of Default, (iii) such holder or holders
shall have offered the Junior Subordinated Indenture Trustee thereunder such
reasonable indemnity as such Junior Subordinated Indenture Trustee may require,
(iv) the Junior Subordinated Indenture Trustee thereunder shall have failed to
institute an action for 60 days thereafter and (v) no inconsistent direction
shall have been given to the Junior Subordinated Indenture Trustee thereunder
during such 60-day period by the holders of a majority in aggregate principal
amount of Junior Subordinated Debt Securities of such series then outstanding
(subject to, in the case of any series of Junior Subordinated Debt Securities
held as trust assets of a Heftel Trust and with respect to which a Security
Exchange has not theretofore occurred, such consent of the holders of the
Preferred Securities and the Common Securities of such Heftel Trust as may be
required under the Declaration of Trust of such Heftel Trust).
 
    The holders of a majority in aggregate principal amount of the Junior
Subordinated Debt Securities of any series affected and then outstanding
(subject to, in the case of any series of Junior Subordinated Debt Securities
held as trust assets of a Heftel Trust and with respect to which a Security
Exchange has not theretofore occurred, such consent of the holders of the
Preferred Securities and the Common Securities of such Heftel Trust as may be
required under the Declaration of Trust of such Heftel Trust) will have the
right, subject to certain limitations, to direct the time, method and place of
conducting any proceeding for any remedy available to the applicable Junior
Subordinated Indenture Trustee or exercising any trust or power conferred on
such Junior Subordinated Indenture Trustee with respect to such series of Junior
Subordinated Debt Securities. The Junior Subordinated Indenture provides that,
in case an Event of

Default shall occur and be continuing, the Junior Subordinated Indenture Trustee
thereunder, in exercising its rights and powers under such Junior Subordinated
Indenture, will be required to use the degree of care of a prudent person in the
conduct of such person's own affairs. Each Junior Subordinated Indenture further
provides that the Junior Subordinated Indenture Trustee thereunder shall not be
required to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties under such Junior Subordinated
Indenture unless it has reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is reasonably assured
to it.
 
    The Company must furnish to the Junior Subordinated Indenture Trustee within
120 days after the end of each fiscal year a statement signed by one of certain
officers of the Company to the effect that a review of the activities of the
Company during such year and of its performance under the Junior Subordinated
Indenture and the terms of the Junior Subordinated Debt Securities has been
made, and, to the best of the knowledge of the signatories based on such review,
the Company has complied with all conditions and covenants of such Junior
Subordinated Indenture through such year or, if the Company is in default,
specifying such default.
 
    If any Junior Subordinated Debt Securities are denominated in a coin or
currency other than that of the United States, then for the purposes of
determining whether the holders of the requisite principal amount of Junior
Subordinated Debt Securities have taken any action as herein described, the
principal amount of such Junior Subordinated Debt Securities shall be deemed to
be that amount of United States dollars that could be obtained for such
principal amount on the basis of the spot rate of exchange into United States
dollars for the currency in which such Junior Subordinated Debt Securities are
denominated (as evidenced to the applicable Junior Subordinated Indenture by an
Officers' Certificate) as of the date the taking of such action by the holders
of such requisite principal amount is evidenced to the applicable Junior
Subordinated Indenture as provided in the respective Junior Subordinated
Indenture.
 
    If any Junior Subordinated Debt Securities are Original Issue Discount
Securities, then for the purposes of determining whether the holders of the
requisite principal amount of Junior Subordinated Debt Securities have taken any
action herein described, the principal amount of such Junior Subordinated Debt
Securities shall be deemed to be the portion of such principal amount that would
be due and payable at the time of the taking of such action upon a declaration
of acceleration of maturity thereof.
 
MODIFICATION OF THE JUNIOR SUBORDINATED INDENTURE
 
    The Junior Subordinated Indenture provides that the Company and the Junior
Subordinated Indenture Trustee may, without the consent of any holders of Junior
Subordinated Debt Securities, enter into supplemental indentures for the
purposes, among other things, of adding to the Company's covenants, adding
additional Junior Subordinated Indenture Events of Default, establishing the
form or terms of any series of Junior Subordinated Debt Securities or curing
ambiguities or inconsistencies in the Junior Subordinated Indenture or making
other provisions.
 
    With certain exceptions, the Junior Subordinated Indenture or the rights of
the holders of the Junior Subordinated Debt Securities may be modified by the
Company and the Junior Subordinated Indenture Trustee with the consent of the
holders of a majority in aggregate principal amount of the Junior Subordinated
Debt Securities of each series affected by such modification then outstanding
(subject to, in the case of any series of Junior Subordinated Debt Securities
held as trust assets of a Heftel Trust and with respect to which a Security
Exchange has not theretofore occurred, such consent of the holders of the
Preferred Securities and the Common Securities of such Heftel Trust as may be
required under the Declaration of Trust of such Heftel Trust), but no such
modification may be made without the consent of the holder of each outstanding
Junior Subordinated Debt Security affected thereby (subject to, in the case of
any series of Junior Subordinated Debt Securities held as trust assets of a
Heftel Trust and with respect to which a Security Exchange has not theretofore
occurred, such consent of the holders of the Preferred Securities and the Common
Securities of such Heftel Trust as may be required under the Declaration of
 
                                      A-21
<PAGE>
Trust of such Heftel Trust) which would (i) change the maturity of any payment
of principal of, or any premium on, or any installment of interest on any Junior
Subordinated Debt Security, or reduce the principal amount thereof or the
interest or any premium thereon, or change the method of computing the amount of
principal thereof or interest thereon on any date or change any place of payment
where, or the coin or currency in which, any Junior Subordinated Debt Security
or any premium or interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the maturity thereof
(or, in the case of redemption or repayment, on or after the redemption date or
the repayment date, as the case may be), (ii) reduce the percentage in principal
amount of the outstanding Junior Subordinated Debt Securities of any series, the
consent of whose holders is required for any such modification, or the consent
of whose holders is required for any waiver of compliance with certain
provisions of the Junior Subordinated Indenture or certain defaults thereunder
and their consequences provided for in such Indenture, or (iii) modify any of
the provisions of certain Sections of the Junior Subordinated Indenture,
including the provisions summarized in this paragraph, except to increase any
such percentage or to provide that certain other provisions of the Junior
Subordinated Indenture cannot be modified or waived without the consent of the
holder of each outstanding Junior Subordinated Debt Security affected thereby.
 
SATISFACTION AND DISCHARGE OF THE JUNIOR SUBORDINATED INDENTURE; DEFEASANCE
 
    The Junior Subordinated Indenture shall generally cease to be of any further
effect with respect to a series of Junior Subordinated Debt Securities if (i)
the Company has delivered to the Junior Subordinated Indenture Trustee for
cancellation all Junior Subordinated Debt Securities of such series (with
certain limited exceptions) or (ii) all Junior Subordinated Debt Securities of
such series not theretofore delivered to the Junior Subordinated Indenture
Trustee for cancellation shall have become due and payable, or are by their
terms to become due and payable within one year or are to be called for
redemption within one year, and the Company shall have deposited with the Junior
Subordinated Indenture Trustee as trust funds the entire amount sufficient (in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Junior
Subordinated Indenture Trustee) without consideration of any reinvestment and
after payment of all taxes or other charges and assessments in respect thereof
payable by the Junior Subordinated Indenture Trustee to pay at maturity or upon
redemption all such Junior Subordinated Debt Securities, no default with respect
to the Junior Subordinated Debt Securities has occurred and is continuing on the
date of such deposit, such deposit does not result in a breach or violation of,
or constitute a default under, the Junior Subordinated Indenture or any other
agreement or instrument to which the Company is a party and the Company
delivered an officers' certificate and an opinion of counsel each stating that
such conditions have been complied with (and if, in either case, the Company
shall also pay or cause to be paid all other sums payable under the Junior
Subordinated Indenture by the Company).
 
    In addition, the Company shall have a "legal defeasance option" (pursuant to
which it may terminate, with respect to the Junior Subordinated Debt Securities
of a particular series, all of its obligations under such Junior Subordinated
Debt Securities and the Junior Subordinated Indenture with respect to such
Junior Subordinated Debt Securities) and a "covenant defeasance option"
(pursuant to which it may terminate, with respect to the Junior Subordinated
Debt Securities of a particular series, its obligations with respect to such
Junior Subordinated Debt Securities under certain specified covenants contained
in the Junior Subordinated Indenture). If the Company exercises its legal
defeasance option with respect to a series of Junior Subordinated Debt
Securities, payment of such Junior Subordinated Debt Securities may not be
accelerated because of an Event of Default. If the Company exercises its
covenant defeasance option with respect to a series of Junior Subordinated Debt
Securities, payment of such Junior Subordinated Debt Securities may not be
accelerated because of an Event of Default related to the specified covenants.
 
                                      A-22
<PAGE>
    The Company may exercise its legal defeasance option or its covenant
defeasance option with respect to the Junior Subordinated Debt Securities of a
series only if (i) the Company irrevocably deposits in trust with the Junior
Subordinated Indenture Trustee cash or U.S. Government Obligations (as defined
in the Junior Subordinated Indenture) for the payment of principal, premium, if
any, and interest with respect to such Junior Subordinated Debt Securities to
maturity or redemption, as the case may be, (ii) the Company delivers to the
Junior Subordinated Indenture Trustee a certificate from a nationally recognized
firm of independent public accountants expressing their opinion that the
payments of principal and interest when due and without reinvestment on the
deposited U.S. Government Obligations plus any deposited money without
investment will provide cash at such times and in such amounts as will be
sufficient to pay the principal, premium, if any, and interest when due with
respect to all the Junior Subordinated Debt Securities of such series to
maturity or redemption, as the case may be, (iii) 91 days pass after the deposit
is made and during the 91-day period no default described in clause (v) under
A--Events of Default, Waiver and Notice Thereof; Junior Subordinated Debt
Securities in Foreign Currencies" above with respect to the Company occurs that
is continuing at the end of such period, (iv) no Default has occurred and is
continuing on the date of such deposit and after giving effect thereto, (v) the
deposit does not constitute a default under any other agreement binding on the
Company, (vi) the Company delivers to the Junior Subordinated Indenture Trustee
an opinion of counsel to the effect that the trust resulting from the deposit
does not constitute, or is qualified as, a regulated investment company under
the Investment Company Act of 1940, (vii) the Company shall have delivered to
the Junior Subordinated Indenture Trustee an opinion of counsel to the effect
that holders of the Junior Subordinated Debt Securities will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such
deposit and defeasance and will be subject to U.S. federal income tax on the
same amounts and in the same manner and at the same times as would have been the
case if such deposit and defeasance had not occurred (and, in the case of legal
defeasance only, such opinion of counsel must be based on a ruling of the
Internal Revenue Service or other change in applicable U.S. federal income tax
law after the date of the applicable Indenture), and (viii) the Company delivers
to the Junior Subordinated Indenture Trustee an officers' certificate and an
opinion of counsel, each stating that all conditions precedent to the defeasance
and discharge of the Junior Subordinated Debt Securities of such series as
contemplated by the Junior Subordinated Indenture have been complied with.
 
    The Junior Subordinated Indenture Trustee shall hold in trust cash or U.S.
Government Obligations deposited with it as described above and shall apply the
deposited cash and the proceeds from deposited U.S. Government Obligations to
the payment of principal, premium, if any, and interest with respect to the
Junior Subordinated Debt Securities of the defeased series.
 
CONCERNING THE JUNIOR SUBORDINATED INDENTURE TRUSTEE
 
    The Junior Subordinated Indenture Trustee for the Junior Subordinated Debt
Securities will be identified in the relevant Prospectus Supplement. In certain
instances, the Company or the holders of a majority of the then outstanding
principal amount of the Junior Subordinated Debt Securities issued under an
Junior Subordinated Indenture may remove the Junior Subordinated Indenture
Trustee and appoint a successor Junior Subordinated Indenture Trustee. The
Junior Subordinated Indenture Trustee may become the owner or pledgee of any of
the Junior Subordinated Debt Securities with the same rights, subject to certain
conflict of interest restrictions, it would have if it were not the Junior
Subordinated Indenture Trustee. The Junior Subordinated Indenture Trustee and
any successor trustee must be a corporation organized and doing business as a
commercial bank or trust company under the laws of the United States or of any
state thereof, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
examination by federal or state authority. From time to time and subject to
applicable law relating to conflicts of interest, the Junior Subordinated
Indenture Trustee may also serve as trustee under other indentures relating to
Debt Securities or Junior Subordinated Debt Securities issued by the Company or
affiliated companies and may
 
                                      A-23
<PAGE>
engage in commercial transactions with the Company and affiliated companies.
Initially, the Junior Subordinated Indenture Trustee is The Bank of New York.
 
CERTAIN COVENANTS OF THE COMPANY APPLICABLE TO THE JUNIOR SUBORDINATED DEBT
  SECURITIES
 
    If Junior Subordinated Debt Securities are issued to a Heftel Trust in
connection with the issuance of Preferred Securities by such Heftel Trust, the
Company covenants in the Junior Subordinated Indenture that, so long as the
Preferred Securities of such Heftel Trust remain outstanding, the Company will
not declare or pay any dividends on, or redeem, purchase, acquire or make a
distribution or liquidation payment with respect to, any Class A Common Stock or
Preferred Stock or make any guarantee payments with respect thereto if at such
time (i) the Company shall be in default with respect to its Guarantee Payments
(as defined herein) or other payment obligations under the related Guarantee,
(ii) there shall have occurred any Junior Subordinated Indenture Event of
Default with respect to such Junior Subordinated Debt Securities, or (iii) in
the event that Junior Subordinated Debt Securities are issued to the applicable
Heftel Trust in connection with the issuance of Preferred Securities by such
Heftel Trust, the Company shall have given notice of its election to defer
payments of interest on such Junior Subordinated Debt Securities by extending
the interest payment period as provided in the terms of the Junior Subordinated
Debt Securities and such period, or any extension thereof, is continuing;
provided, however, that the foregoing restrictions shall not apply to (a)
dividends, redemptions, purchases, acquisitions, distributions or payments made
by the Company by way of issuance of shares of its capital stock, (b) any
declaration of a dividend under a shareholder rights plan or in connection with
the implementation of a shareholder rights plan, the issuance of capital stock
of the Company under a shareholder rights plan or the redemption or repurchase
of any such right distributed pursuant to a shareholder rights plan, (c)
payments of accrued dividends by the Company upon the redemption, exchange or
conversion of any Preferred Stock as may be outstanding from time to time in
accordance with the terms of such Preferred Stock, (d) cash payments made by the
Company in lieu of delivering fractional shares upon the redemption, exchange or
conversion of any Preferred Stock as may be outstanding from time to time in
accordance with the terms of such Preferred Stock, (e) payments under the
Guarantees, or (f) purchases of Class A Common Stock related to the issuance of
Class A Common Stock or rights under any of the Company's benefit plans for its
directors, officers or employees, or related to the issuance of Class A Common
Stock or rights under a dividend reinvestment and stock purchase plan. In
addition, if Junior Subordinated Debt Securities are issued to a Heftel Trust in
connection with the issuance of Preferred Securities by such Heftel Trust, for
so long as the Preferred Securities of such Heftel Trust remain outstanding, the
Company has agreed (1) to remain the sole direct or indirect owner of all the
outstanding Common Securities issued by such Heftel Trust and not to cause or
permit such Common Securities to be transferred except to the extent permitted
by the Declaration of such Heftel Trust; provided that any permitted successor
of the Company under the Junior Subordinated Indenture may succeed to the
Company's ownership of such Common Securities, (2) to comply fully with all its
obligations and agreements under such Declaration and (3) not to take any action
which would cause such Heftel Trust to cease to be treated as a grantor trust
for federal income tax purposes, except in connection with a distribution of
Junior Subordinated Debt Securities.
 
SUBORDINATION
 
    The Junior Subordinated Debt Securities will be subordinated and junior in
right of payment to certain other indebtedness of the Company to the extent set
forth in the applicable Prospectus Supplement.
 
    The payment of the principal of, premium, if any, and interest on the Junior
Subordinated Debt Securities will be subordinated in right of payment to the
prior payment in full of all Senior Indebtedness of the Company and pari passu
with the Company's trade creditors. No payment on account of principal of,
premium, if any, or interest on the Junior Subordinated Debt Securities and no
acquisition of, or
 
                                      A-24
<PAGE>
payment on account of any sinking fund for, the Junior Subordinated Debt
Securities may be made unless full payment of amounts then due for principal,
premium, if any, and interest then due on all Senior Indebtedness by reason of
the maturity thereof (by lapse of time, acceleration or otherwise) has been made
or duly provided for in cash or in a manner satisfactory to the holders of such
Senior Indebtedness. In addition, the Junior Subordinated Indenture provides
that if a default has occurred giving the holders of such Senior Indebtedness
the right to accelerate the maturity thereof, or an event has occurred which,
with the giving of notice, or lapse of time, or both, would constitute such an
event of default, then unless and until such event shall have been cured or
waived or shall have ceased to exist, no payment on account of principal,
premium, if any, or interest on the Junior Subordinated Debt Securities and no
acquisition of, or payment on account of a sinking fund for, the Junior
Subordinated Debt Securities may be made. The Company shall give prompt written
notice to the Junior Subordinated Indenture Trustee of any default under any
Senior Indebtedness or under any agreement pursuant to which Senior Indebtedness
may have been issued. The Junior Subordinated Indenture provisions described in
this paragraph, however, do not prevent the Company from making a sinking fund
payment with Junior Subordinated Debt Securities acquired prior to the maturity
of Senior Indebtedness or, in the case of default, prior to such default and
notice thereof. Upon any distribution of its assets in connection with any
dissolution, liquidation or reorganization of the Company, all Senior
Indebtedness must be paid in full before the holders of the Junior Subordinated
Debt Securities are entitled to any payments whatsoever. As a result of these
subordination provisions, in the event of the Company's insolvency, holders of
the Junior Subordinated Debt Securities may recover ratably less than senior
creditors of the Company.
 
    For purposes of the description of the Junior Subordinated Debt Securities,
the term "Senior Indebtedness" means the principal of and premium, if any, and
interest on the following, whether outstanding on the date of execution of the
Junior Subordinated Indenture or thereafter incurred or created, (i)
indebtedness of the Company for money borrowed by the Company (including
purchase money obligations with an original maturity in excess of one year) or
evidenced by securities (other than the Junior Subordinated Debt Securities),
notes, bankers' acceptances or other corporate debt securities or similar
instruments issued by the Company; (ii) obligations with respect to letters of
credit; (iii) indebtedness of the Company constituting a guarantee of
indebtedness of others of the type referred to in the preceding clauses (i) and
(ii); or (iv) renewals, extensions or refundings of any of the indebtedness
referred to in the preceding clauses (i), (ii) and (iii) unless, in the case of
any particular indebtedness, renewal, extension or refunding, under the express
provisions of the instrument creating or evidencing the same, or pursuant to
which the same is outstanding, such indebtedness or such renewal, extension or
refunding thereof is not superior in right of payment to the Junior Subordinated
Debt Securities. See "Holding Company Structure and Secured Claims."
 
                         DESCRIPTION OF PREFERRED STOCK
 
    Upon obtaining the consent of the holders of Class B Common Stock as
described in "Description of Common Stock--Class B Common Stock," the Board of
Directors has the authority to issue up to 5,000,000 shares of Preferred Stock,
in one or more series, and to fix the rights, preferences, privileges, and
qualifications thereof without any further vote or action by the stockholders.
The issuance of Preferred Stock could decrease the amount of earnings and assets
available for distribution to holders of Class A and Class B Common Stock, and
adversely affect the rights and powers, including voting rights, of such holders
and may have the effect of delaying, deferring or preventing a change in control
of the Company. There are currently no shares of Preferred Stock issued or
outstanding. The particular terms of any series of Preferred Stock will be
described in the applicable Prospectus Supplement.
 
                                      A-25
<PAGE>
                          DESCRIPTION OF COMMON STOCK
 
    The Board of Directors has the authority to issue up to 50,000,000 shares of
Class A Common Stock, $.001 par value per share, and 50,000,000 shares of Class
B Common Stock, $.001 par value per share. As of December 9, 1997, 29,978,748
shares of Class A Common Stock and 14,156,470 shares of Class B Common Stock
were outstanding.
 
    The rights of holders of shares of Class A and Class B Common Stock are
identical except for voting rights and certain rights of the Class B Common
Stock relating to its conversion to Class A Common Stock. Holders of Class A and
Class B Common Stock are entitled to ratably receive dividends, if any, as may
be declared from time to time by the Board of Directors from funds legally
available therefor, subject to the payment of any preferential dividends
declared with respect to any Preferred Stock that from time to time may be
outstanding. Upon liquidation, dissolution or winding up of the Company, holders
of Class A Common Stock are entitled to share ratably in any assets available
for distribution to stockholders after payment of all obligations of the
Company, subject to the rights to receive preferential distributions of the
holders of any shares of Preferred Stock then outstanding.
 
    Holders of Class A and Class B Common Stock do not have cumulative voting
rights or preemptive or other rights to acquire or subscribe to additional,
unissued or treasury shares. The shares of Class A and Class B Common Stock
currently outstanding are, and the shares of Class A Common Stock offered hereby
will be, upon issuance thereof, validly issued, fully paid and nonassessable.
 
CLASS A COMMON STOCK
 
    Holders of shares of Class A Common Stock are entitled to one vote per share
on all matters submitted to a vote of the stockholders.
 
CLASS B COMMON STOCK
 
    Holders of the Class B Common Stock will, in certain circumstances, have
certain voting rights, with each share of Class B Common Stock being entitled to
one vote. Specifically, so long as Clear Channel Communications, Inc. ("Clear
Channel") and its affiliates own at least 20% of the Common Stock then
outstanding, the Company will not be able to, and will not be able to permit any
subsidiary to, without the vote or consent by the holders of a majority of the
Class B Common Stock voting as a single class, take any of the following
actions: (i) effect the sale, lease or other transfer of all or substantially
all of the assets of the Company, or any merger or consolidation involving the
Company where the stockholders of the Company immediately prior to such
transaction would not own at least 50% of the capital stock of the surviving
entity, or any reclassification, recapitalization, dissolution, liquidation or
winding up of the Company; (ii) authorize, issue or obligate itself to issue any
shares of Preferred Stock; (iii) make or permit any amendment to the Company's
certificate of incorporation that adversely affects the rights of the holders of
Class B Common Stock; (iv) declare or pay any non-cash dividends on or make any
other non-cash distribution on the Company's Common Stock; or (v) make or permit
any amendment or modification to the Company's certificate of incorporation
concerning the Company's capital stock.
 
    The Company's Certificate of Incorporation provides that only Clear Channel
and its affiliates may own shares of Class B Common Stock. The outstanding Class
B Common Stock will convert into Class A Common Stock automatically upon sale,
gift or other transfer to a person or entity other than Clear Channel or an
affiliate of Clear Channel. Each share of the Class B Common Stock will also be
convertible into Class A Common Stock at the option of its holder subject to
necessary FCC consents. In addition, Clear Channel may convert shares of Class A
Common Stock held by it into shares of Class B Common Stock at its option.
 
    As of December 9, 1997, Clear Channel owned approximately 32% of the
outstanding shares of Class A and Class B Common Stock of the Company and all
14,156,470 shares of Class B Common Stock.
 
                                      A-26
<PAGE>
    Upon consummation of the Company's merger with Tichenor Media System, Inc.,
on February 14, 1997 (the "Tichenor Merger"), the FCC's cross-interest policy
prohibited Clear Channel from owning more than 33.3% of the total outstanding
Common Stock of the Company. The FCC's cross interest policy bars a party which
holds an attributable interest in one or more radio stations in a market from
having a "meaningful relationship" with another radio station in that market. A
"meaningful relationship" is construed by the FCC to include a non-voting equity
position in excess of 33.3% of the total outstanding Common Stock.
 
REGISTRATION RIGHTS AGREEMENTS; STOCKHOLDERS AGREEMENT; VOTING AGREEMENT
 
    In connection with the Company's merger with Tichenor Media System, Inc. on
February 14, 1997 (the "Tichenor Merger"), the Company entered into a
Registration Rights Agreement, dated February 14, 1997, by and among the Company
and the various stockholders named therein (the "Registration Rights
Agreement"), pursuant to which the Company granted certain demand and
"piggyback" registration rights to certain former Tichenor stockholders who own,
as of December 9, 1997, an aggregate of 8,608,338 shares of Class A Common Stock
(collectively, the "Major Tichenor Stockholders"). The Company also entered into
a Registration Rights Agreement, dated February 14, 1997, between the Company
and Clear Channel (the "Clear Channel Registration Rights Agreement"), pursuant
to which the Company granted certain demand and piggyback registration rights to
Clear Channel with respect to any shares of Class A Common Stock that may be
held from time to time by Clear Channel following the Tichenor Merger. Upon
consummation of the Tichenor Merger, Clear Channel and the Major Tichenor
Stockholders also entered into a Stockholders Agreement with the Company whereby
such stockholders agreed to certain restrictions on the transfer of their shares
of Class A Common Stock of the Company and granted certain rights of first
refusal and "tag-along" rights with respect to certain sales of such shares. In
addition, on July 1, 1996, the McHenry T. Tichenor, Jr., the Chairman, President
and Chief Executive Officer of the Company, McHenry T. Tichenor, Sr., David T.
Tichenor, Warren W. Tichenor, William E. Tichenor, and Jean T. Russell
(collectively, the "Tichenor Family") entered into a Voting Agreement with one
another pursuant to which the shares of Class A Common Stock held by them shall
be voted in accordance with the instructions of the holders of a majority of
such shares. As of December 9, 1997, the Tichenor Family or their successors own
approximately 26.9% of the shares of Class A Common Stock and approximately
18.2% of the combined Class A and Class B Common Stock then outstanding.
 
CERTAIN ANTI-TAKEOVER EFFECTS OF CHARTER AND DELAWARE LAW
 
    Certain provisions of the Company's Certificate of Incorporation and the
Delaware General Corporation Law ("DGCL") may have the effect of impeding the
acquisition of control of the Company by means of a tender offer, proxy fight,
open market purchases or otherwise.
 
    As provided in the Company's Certificate of Incorporation, holders of Class
B Common Stock will have the right to vote separately as a class on certain
matters, including a merger of the Company or sale of all or substantially all
of its assets. In addition, shares of Class B Common Stock are convertible into
shares of Class A Common Stock at the holder's option, subject to the receipt of
applicable regulatory approvals.
 
    Section 203 of the DGCL restricts a wide range of transactions ("business
combinations") between a corporation and an interested stockholder. An
"interested stockholder" is, generally, any person who beneficially owns,
directly or indirectly, 15% or more of the corporation's outstanding voting
stock. Business combinations are broadly defined to include (i) mergers or
consolidations with, (ii) sales or other dispositions of more than 10% of the
corporation's assets to, (iii) certain transactions which would result in
increasing the proportionate share of stock of the corporation or any subsidiary
owned by, or (iv) receipt of the benefit (other than proportionately as a
stockholder) or any loans, advances or other financial benefits by, an
interested stockholder. Section 203 provides that an interested stockholder may
not engage in a business combination with a corporation for a period of three
years from the time of becoming an interested stockholder unless (i) the board
of directors approved either the business combination or the
 
                                      A-27
<PAGE>
transaction which resulted in the person becoming an interested stockholder
prior to the time such person became an interested stockholder; (ii) upon
consummation of the transaction which resulted in the person becoming an
interested stockholder, that person owned at least 85% of the corporation's
voting stock (excluding shares owned by persons who are officers and also
directors and shares owned by certain employee stock plans); or (iii) the
business combination is approved by the board of directors and authorized by the
affirmative vote of at least 66 2/3% of the outstanding voting stock not owned
by the interested stockholder.
 
FOREIGN OWNERSHIP
 
    The Company's Certificate of Incorporation restricts the ownership and
voting of the Company's capital stock, including its Class A Common Stock, in
accordance with the Communications Act and the rules of the FCC to prohibit
ownership of more than 25% of the Company's outstanding capital stock (or
control of more than 25% of the voting power it represents) by or for the
account of aliens, foreign governments, or non-U.S. corporations or corporations
otherwise subject to control by such persons or entities. The Restated
Certificate of Incorporation also prohibits any transfer of the Company's
capital stock which would cause the Company to violate this prohibition. In
addition, the Restated Certificate of Incorporation authorizes the Company's
Board of Directors to adopt such provisions as it deems necessary to enforce
these prohibitions.
 
                            DESCRIPTION OF WARRANTS
 
    The Company may issue Warrants for the purchase of Debt Securities or Junior
Subordinated Debt Securities, or shares of Preferred Stock or Class A Common
Stock. Warrants may be issued independently or together with any Debt
Securities, Junior Subordinated Debt Securities, or shares of Preferred Stock or
Class A Common Stock offered by any Prospectus Supplement and may be attached to
or separate from such Debt Securities, Junior Subordinated Debt Securities, or
shares of Preferred Stock or Class A Common Stock. The Warrants are to be issued
under Warrant Agreements to be entered into between the Company and The Bank of
New York, as Warrant Agent, or such other bank or trust company as is named in
the Prospectus Supplement relating to the particular issue of Warrants (the
"Warrant Agent"). The Warrant Agent will act solely as an agent of the Company
in connection with the Warrants and will not assume any obligation or
relationship of agency or trust for or with any holders of Warrants or
beneficial owners of Warrants. The following summaries of certain provisions of
the form of Warrant Agreement and Warrants do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all the
provisions of the applicable Warrant Agreement and the Warrants.
 
GENERAL
 
    If Warrants are offered, the Prospectus Supplement will describe the terms
of the Warrants, including the following: (i) the offering price; (ii) the
currency, currencies or currency units for which Warrants may be purchased;
(iii) the designation, aggregate principal amount, currency, currencies or
currency units and terms of the Debt Securities or Junior Subordinated Debt
Securities purchasable upon exercise of the Debt Warrants and the price at which
such Debt Securities or Junior Subordinated Debt Securities may be purchased
upon such exercise; (iv) the designation, number of shares and terms of the
Preferred Stock purchasable upon exercise of the Preferred Stock Warrants and
the price at which such shares of Preferred Stock may be purchased upon such

Stock or Class A Common Stock; (vii) if applicable, the date on and after which
the Warrants and the related Debt Securities, Junior
 
                                      A-28
<PAGE>
Subordinated Debt Securities, Preferred Stock or Class A Common Stock will be
separately transferable; (viii) the date on which the right to exercise the
Warrants shall commence and the date (the "Expiration Date") on which such right
shall expire; (ix) whether the Warrants will be issued in registered or bearer
form; (x) a discussion of certain federal income tax, accounting and other
special considerations, procedures and limitations relating to the Warrants; and
(xi) any other terms of the Warrants.
 
    Warrants may be exchanged for new Warrants of different denominations, may
(if in registered form) be presented for registration of transfer, and may be
exercised at the corporate trust office of the Warrant Agent or any other office
indicated in the Prospectus Supplement. Before the exercise of their Warrants,
holders of Warrants will not have any of the rights of holders of the Debt
Securities, Junior Subordinated Debt Securities or shares of Preferred Stock or
Class A Common Stock purchasable upon such exercise, including the right to
receive payments of principal of, any premium on, or any interest on, the Debt
Securities or Junior Subordinated Debt Securities purchasable upon such exercise
or to enforce the covenants in the Indenture or to receive payments of
dividends, if any, on the Preferred Stock or Class A Common Stock purchasable
upon such exercise or to exercise any applicable right to vote. If the Company
maintains the ability to reduce the exercise price of any Stock Warrant and such
right is triggered, the Company will comply with the federal securities laws,
including Rule 13e-4 under the Exchange Act, to the extent applicable.
 
EXERCISE OF WARRANTS
 
    Each Warrant will entitle the holder to purchase such principal amount of
Debt Securities or Junior Subordinated Debt Securities or such number of shares
of Preferred Stock or Class A Common Stock at such exercise price as shall in
each case be set forth in, or calculable from, the Prospectus Supplement
relating to the Warrant. Warrants may be exercised at such times as are set
forth in the Prospectus Supplement relating to such Warrants. After the close of
business on the Expiration Date (or such later date to which such Expiration
Date may be extended by the Company), unexercised Warrants will become void.
 
    Subject to any restrictions and additional requirements that may be set
forth in the Prospectus Supplement relating thereto, Warrants may be exercised
by delivery to the Warrant Agent of the certificate evidencing such Warrants
properly completed and duly executed and of payment as provided in the
Prospectus Supplement of the amount required to purchase the Debt Securities,
Junior Subordinated Debt Securities or shares of Preferred Stock or Class A
Common Stock purchasable upon such exercise. The exercise price will be the
price applicable on the date of payment in full, as set forth in the Prospectus
Supplement relating to the Warrants. Upon receipt of such payment and the
certificate representing the Warrants to be exercised, properly completed and
duly executed at the corporate trust office of the Warrant Agent or any other
office indicated in the Prospectus Supplement, the Company will, as soon as
practicable, issue and deliver the Debt Securities, Junior Subordinated Debt
Securities or shares of Preferred Stock or Class A Common Stock purchasable upon
such exercise. If fewer than all of the Warrants represented by such certificate
are exercised, a new certificate will be issued for the remaining amount of
Warrants.
 
ADDITIONAL PROVISIONS
 
    The exercise price payable and the number of shares of Common or Preferred
Stock purchasable upon the exercise of each Stock Warrant will be subject to
adjustment in certain events, including the issuance of a stock dividend to
holders of Common or Preferred Stock, respectively, or a combination,
subdivision or reclassification of Common or Preferred Stock, respectively. In
lieu of adjusting the number of shares of Class A Common or Preferred Stock
purchasable upon exercise of each Stock Warrant, the Company may elect to adjust
the number of Stock Warrants. No adjustment in the number of shares purchasable
upon exercise of the Stock Warrants will be required until cumulative
adjustments require an adjustment of at least 1% thereof. The Company may, at
its option, reduce the exercise price at any time.
 
                                      A-29
<PAGE>
No fractional shares will be issued upon exercise of Stock Warrants, but the
Company will pay the cash value of any fractional shares otherwise issuable.
Notwithstanding the foregoing, in case of any consolidation, merger, or sale or
conveyance of the property of the Company as an entirety or substantially as an
entirety, the holder of each outstanding Stock Warrant shall have the right upon
the exercise thereof to the kind and amount of shares of stock and other
securities and property (including cash) receivable by a holder of the number of
shares of Class A Common Stock or Preferred Stock into which such Stock Warrants
were exercisable immediately prior thereto.
 
NO RIGHTS AS STOCKHOLDERS
 
    Holders of Stock Warrants will not be entitled, by virtue of being such
holders, to vote, to consent, to receive dividends, to receive notice as
stockholders with respect to any meeting of stockholders for the election of
directors of the Company or any other matter, or to exercise any rights
whatsoever as stockholders of the Company.
 
                         DESCRIPTION OF STOCK PURCHASE
                       CONTRACTS AND STOCK PURCHASE UNITS
 
    The Company may issue Stock Purchase Contracts, which are contracts
obligating holders to purchase from the Company, and the Company to sell to the
holders, a specified number of shares of Class A Common Stock or Preferred Stock
at a future date or dates. The price per share of Class A Common Stock or
Preferred Stock may be fixed at the time the Stock Purchase Contracts are issued
or may be determined by reference to a specific formula set forth in the Stock
Purchase Contracts. Any such formula may include anti-dilution provisions to
adjust the number of shares issuable pursuant to Stock Purchase Contracts upon
certain events. The Stock Purchase Contracts may be issued separately or as a
part of Stock Purchase Units each representing ownership of a Stock Purchase
Contract and Debt Securities, Preferred Securities or U.S. Obligations, securing
the holders' obligations to purchase the Class A Common Stock or the Preferred
Stock under the Purchase Contracts.
 
    Except as otherwise described in the applicable Prospectus Supplement, in
the case of Stock Purchase Units that include Debt Securities or Preferred
Securities, in the absence of any such early settlement or the election by a
holder to pay the consideration specified in the Stock Purchase Contracts, the
Debt Securities or Preferred Securities will automatically be presented to the
applicable Heftel Trust for redemption at 100% of face or liquidation value and
the Heftel Trust will present Junior Subordinated Debt Securities in an equal
principal amount to the Company for redemption at 100% of principal amount.
Amounts received in respect of such redemption will automatically be transferred
to the Company and applied to satisfy in full the holder's obligation to
purchase Class A Common Stock or Preferred Stock under the Stock Purchase
Contracts. The Stock Purchase Contracts may require the Company to make periodic
payments to the holders of the Stock Purchase Units or vice versa, and such
payments may be unsecured or refunded on some basis. The Stock Purchase
Contracts may require holders to secure their obligations thereunder in a
specified manner.
 
    Except as otherwise described in the applicable Prospectus Supplement,
holders of Stock Purchase Units may be entitled to settle the underlying Stock
Purchase Contracts prior to the stated settlement date by surrendering the
certificate evidencing the Stock Purchase Units, accompanied by the payment due,
in such form and calculated pursuant to such formula as may be prescribed in the
Stock Purchase Contracts and described in the applicable Prospectus Supplement.
Upon early settlement, the holder would receive the number of shares of Class A
Common Stock or Preferred Stock deliverable under such Stock Purchase Contracts,
subject to adjustment in certain cases. Holders of Stock Purchase Units may be
entitled to exchange their Stock Purchase Units together with appropriate
collateral, for separate Stock Purchase Contracts and Preferred Securities, Debt
Securities or Junior Subordinated Debt Securities. In the event of
 
                                      A-30
<PAGE>
either such early settlement or exchange, the Preferred Securities, Debt
Securities, Junior Subordinated Debt Securities or debt obligations that were
pledged as security for the obligation of the holder to perform under the Stock
Purchase Contracts would be transferred to the holder free and clear of the
Company's security interest therein.
 
    The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units including differences, if any, from
the term described above.
 
                      DESCRIPTION OF PREFERRED SECURITIES
 
PREFERRED SECURITIES
 
    Each Heftel Trust may issue, from time to time, only one series of Preferred
Securities having terms described in the Prospectus Supplement relating thereto.
The Declaration of each Heftel Trust authorizes the Regular Trustees of such
Heftel Trust to issue on behalf of such Heftel Trust one series of Preferred
Securities. Each Declaration will be qualified as an indenture under the Trust
Indenture Act. The Preferred Securities will have such terms, including
distributions, redemption, voting, liquidation rights and such other preferred,
deferred or other special rights or such restrictions as shall be set forth in
the related Declaration or made part of such Declaration by the Trust Indenture
Act. Reference is made to the Prospectus Supplement relating to the Preferred
Securities of a Heftel Trust for specific terms, including (i) the specific
designation of such Preferred Securities, (ii) the number of Preferred
Securities issued by such Heftel Trust, (iii) the annual distribution rate (or
method of calculation thereof) for Preferred Securities issued by such Heftel
Trust, the date or dates upon which such distributions shall be payable and the
record date or dates for the payment of such distributions, (iv) whether
distributions on Preferred Securities issued by such Heftel Trust shall be
cumulative, and, in the case of Preferred Securities having such cumulative
distribution rights, the date or dates or method of determining the date or
dates from which distributions on Preferred Securities issued by such Heftel
Trust shall be cumulative, (v) the amount or amounts which shall be paid out of
the assets of such Heftel Trust to the holders of Preferred Securities of such
Heftel Trust upon voluntary or involuntary liquidation, dissolution, winding-up
or termination of such Heftel Trust, (vi) the obligation or right, if any, of
such Heftel Trust to purchase or redeem Preferred Securities issued by such
Heftel Trust and the price or prices at which, the period or periods within
which and the terms and conditions upon which Preferred Securities issued by
such Heftel Trust shall or may be purchased or redeemed, in whole or in part,
pursuant to such obligation or right, (vii) the voting rights, if any, of
Preferred Securities issued by such Heftel Trust in addition to those required
by law, including the number of votes per Preferred Security and any requirement
for the approval by the holders of Preferred Securities, or of Preferred
Securities issued by one or more Heftel Trusts, or of both, as a condition to
specified actions or amendments to the Declaration of such Heftel Trust, (viii)
the terms and conditions upon which the Preferred Securities may be convertible
into or exchanged for Class A Common Stock, Preferred Stock, Debt Securities,
Junior Subordinated Debt Securities, or indebtedness or other securities of any
kind of the Company; and (ix) any other relevant rights, preferences,
privileges, limitations or restrictions of Preferred Securities issued by such
Heftel Trust consistent with the Declaration of such Heftel Trust or with
applicable law. All Preferred Securities offered hereby will be guaranteed by
the Company as and to the extent set forth below under "Description of the
Guarantees." Certain federal income tax considerations applicable to any
offering of Preferred Securities will be described in the Prospectus Supplement
relating thereto.
 
    In connection with the issuance of Preferred Securities, each Heftel Trust
will issue one series of Common Securities. The Declaration of each Heftel Trust
authorizes the Regular Trustees of such Heftel Trust to issue on behalf of such
Heftel Trust one series of Common Securities having such terms including
distributions, redemption, voting, liquidation rights or such restrictions as
shall be set forth therein. The terms of the Common Securities issued by a
Heftel Trust will be substantially identical to the terms of the Preferred
Securities issued by such Heftel Trust and the Common Securities will rank pari
passu and payments will be made thereon on a pro rata basis with the Preferred
Securities except that, if a
 
                                      A-31
<PAGE>
Declaration Event of Default occurs and is continuing, the rights of the holders
of such Common Securities to payment in respect of distributions and payments
upon liquidation, redemption and maturity will be subordinated to the rights of
the holders of such Preferred Securities. Except in certain limited
circumstances, the Common Securities issued by a Heftel Trust will also carry
the right to vote and to appoint, remove or replace any of the Trustees of such
Heftel Trust. All the Common Securities of a Heftel Trust will be directly or
indirectly owned by the Company.
 
    As long as payments of interest and other payments are made when due on the
Junior Subordinated Debt Securities, such payments will be sufficient to cover
distributions and other payments due on the Preferred Securities primarily
because (i) the aggregate principal amount of Junior Subordinated Debt
Securities held as trust assets will be equal to the sum of the aggregate stated
liquidation amount of the Preferred Securities; and (ii) the interest rate and
interest and other payment dates on the Junior Subordinated Debt Securities will
match the distribution rate and distribution and other payment dates for the
Preferred Securities.
 
    If an Event of Default with respect to the Declaration of any Heftel Trust
occurs and is continuing, then the holders of Preferred Securities of such
Heftel Trust would rely on the enforcement by the Property Trustee of its rights
as a holder of the Junior Subordinated Debt Securities deposited in such Heftel
Trust against the Company. In addition, the holders of a majority in liquidation
amount of such Preferred Securities will have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee or to direct the exercise of any trust or power conferred upon
the Property Trustee under such Declaration, including the right to direct the
Property Trustee to exercise the remedies available to it as a holder of such
Junior Subordinated Debt Securities. If the Property Trustee fails to enforce
its rights under such Junior Subordinated Debt Securities deposited in such
Heftel Trust, any holder of such Preferred Securities may, to the extent
permitted by applicable law, after a period of 60 days has elapsed from such
holder's written request, institute a legal proceeding against the Company to
enforce the Property Trustee's rights under such Junior Subordinated Debt
Securities without first instituting any legal proceeding against the Property
Trustee or any other person or entity. If an Event of Default with respect to
the Declaration of any Heftel Trust occurs and is continuing and such event is
attributable to the failure of the Company to pay interest or principal on the
Junior Subordinated Debt Securities on the date such interest or principal is
otherwise payable (or in the case of redemption, on the redemption date), then a
holder of Preferred Securities of such Heftel Trust may also directly institute
a proceeding for enforcement of payment to such holder of the principal of or
interest on such Junior Subordinated Debt Securities having a principal amount
equal to the aggregate liquidation amount of such Preferred Securities held by
such holder (a "Direct Action") on or after the respective due date specified in
such Junior Subordinated Debt Securities without first (i) directing the
Property Trustee to enforce the terms of such Junior Subordinated Debt
Securities or (ii) instituting a legal proceeding against the Company to enforce
the Property Trustee's rights under such Junior Subordinated Debt Securities. In
connection with such Direct Action, the Company will be subrogated to the rights
of such holder of such Preferred Securities under such Declaration to the extent
of any payment made by the Company to such holder of such Preferred Securities
in such Direct Action. The holders of Preferred Securities of a Heftel Trust
will not be able to exercise directly any other remedy available to the holders
of the Junior Subordinated Debt Securities unless the Property Trustee first
fails to do so.
 
    Certain federal income tax considerations applicable to an investment in
Preferred Securities will be described in the Prospectus Supplement relating
thereto.
 
                           DESCRIPTION OF GUARANTEES
 
    Set forth below is a summary of information concerning the Guarantees that
will be executed and delivered by the Company for the benefit of the holders
from time to time of Preferred Securities of a Heftel Trust. Each Preferred
Security Guarantee will be separately qualified under the Trust Indenture Act
and will be held by The Bank of New York, acting in its capacity as indenture
trustee with respect thereto
 
                                      A-32
<PAGE>
(the "Guarantee Trustee"), for the benefit of holders of the Preferred
Securities of the applicable Heftel Trust. The terms of each Guarantee will be
those set forth in such Guarantee and those made part of such Guarantee by the
Trust Indenture Act. This description summarizes the material terms of the
Guarantees and is qualified in its entirety by reference to the form of
Guarantee, which is filed as an exhibit to the Registration Statement of which
this Prospectus forms a part, and the Trust Indenture Act.
 
GENERAL
 
    Pursuant to each Guarantee, the Company will irrevocably and unconditionally
agree, to the extent set forth therein, to pay in full, to the holders of the
Preferred Securities issued by the applicable Heftel Trust, the Guarantee
Payments (as defined herein), to the extent not paid by such Heftel Trust,
regardless of any defense, right of set-off or counterclaim that such Heftel
Trust may have or assert. The following distributions and other payments with
respect to Preferred Securities issued by a Heftel Trust to the extent not made
or paid by such Heftel Trust (the "Guarantee Payments"), will be subject to the
Guarantee (without duplication): (i) any accrued and unpaid distributions on
such Preferred Securities, but only if and to the extent that in each case the
Company has made a payment to the Property Trustee of interest on the Junior
Subordinated Debt Securities, (ii) the redemption price, including all accrued
and unpaid distributions to the date of redemption, with respect to any
Preferred Securities called for redemption by such Heftel Trust, but only if and
to the extent that in each case the Company has made a payment to the Property
Trustee of interest or principal on the Junior Subordinated Debt Securities
deposited in such Heftel Trust as trust assets, and (iii) upon a voluntary or
involuntary liquidation, dissolution, winding-up or termination of such Heftel
Trust (other than in connection with the distribution of such Junior
Subordinated Debt Securities to the holders of such Preferred Securities or the
redemption of all such Preferred Securities upon the maturity or redemption of
such Junior Subordinated Debt Securities) the lesser of (a) the aggregate of the
liquidation amount and all accrued and unpaid distributions on such Preferred
Securities to the date of payment, to the extent such Heftel Trust has funds
available therefor, and (b) the amount of assets of such Heftel Trust remaining
available for distribution to holders of such Preferred Securities upon
liquidation of such Heftel Trust. The Company's obligation to make a Guarantee
Payment may be satisfied by direct payment of the required amounts by the
Company to the holders of the applicable Preferred Securities or by causing the
applicable Heftel Trust to pay such amounts to such holders.
 
    The Guarantee is a full and unconditional guarantee from the time of
issuance of the applicable Preferred Securities, but the Guarantee covers
distributions and other payments on such Preferred Securities only if and to the
extent that the Company has made a payment to the Property Trustee of interest
or principal on the Junior Subordinated Debt Securities deposited in the
applicable Heftel Trust as trust assets. If the Company does not make interest
or principal payments on the Junior Subordinated Debt Securities deposited in
the applicable Heftel Trust as trust assets, the Property Trust will not make
distributions on the Preferred Securities of such Heftel Trust and the Heftel
Trust will not have funds available therefor.
 
    The Company's obligations under the Declaration for each Heftel Trust, the
Guarantee issued with respect to Preferred Securities issued by such Heftel
Trust, the Junior Subordinated Debt Securities purchased by such Heftel Trust
and the Junior Subordinated Indenture in the aggregate will provide a full and
unconditional guarantee on a subordinated basis by the Company of payments due
on the Preferred Securities issued by such Heftel Trust.
 
CERTAIN COVENANTS OF THE COMPANY
 
    In each Guarantee, the Company will covenant that, so long as any Preferred
Securities issued by the applicable Heftel Trust remain outstanding, the Company
will not declare or pay any dividends on, or redeem, purchase, acquire or make a
distribution or liquidation payment with respect to, any Class A Common Stock,
Class B Common Stock or Preferred Stock or make any guarantee payment with
respect
 
                                      A-33
<PAGE>
thereto, if at such time (i) the Company shall be in default with respect to its
Guarantee Payments or other payment obligations under such Guarantee, (ii) there
shall have occurred any Event of Default under the related Declaration or (iii)
in the event that Junior Subordinated Debt Securities are issued to the
applicable Heftel Trust in connection with the issuance of Preferred Securities
by such Heftel Trust, the Company shall have given notice of its election to
defer payments of interest on such Junior Subordinated Debt Securities by
extending the interest payment period as provided in the terms of the Junior
Subordinated Debt Securities and such period, or any extension thereof, is
continuing; provided, however, that the foregoing restrictions shall not apply
to (a) dividends, redemptions, purchases, acquisitions, distributions or
payments made by the Company by way of issuance of shares of its capital stock,
(b) any declaration of a dividend under a shareholder rights plan or in
connection with the implementation of a shareholder rights plan, the issuance of
capital stock of the Company under a shareholder rights plan or the redemption
or repurchase of any such right distributed pursuant to a shareholder rights
plan, (c) payments of accrued dividends by the Company upon the redemption,
exchange or conversion of any Preferred Stock as may be outstanding from time to
time in accordance with the terms of such Preferred Stock, (d) cash payments
made by the Company in lieu of delivering fractional shares upon the redemption,
exchange or conversion of any Preferred Stock as may be outstanding from time to
time in accordance with the terms of such Preferred Stock, (e) payments under
the Guarantees, or (f) purchases of Class A Common Stock related to the issuance
of Common Stock or rights under any of the Company's benefit plans for its
directors, officers or employees, or related to the issuance of Common Stock or
rights under a dividend reinvestment and stock purchase plan. In addition, so
long as any Preferred Securities of a Heftel Trust remain outstanding, the
Company has agreed (1) to remain the sole direct or indirect owner of all the
outstanding Common Securities issued by such Heftel Trust and not to cause or
permit such Common Securities to be transferred except to the extent permitted
by the Declaration of such Heftel Trust, provided that any permitted successor
of the Company under the Junior Subordinated Indenture may succeed to the
Company's ownership of such Common Securities, and (2) to use reasonable efforts
to cause such Heftel Trust to continue to be treated as a grantor trust for
federal income tax purposes, except in connection with a distribution of Junior
Subordinated Debt Securities.
 
AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes that do not adversely affect the rights
of holders of the applicable Preferred Securities (in which case no consent will
be required), each Guarantee may be amended only with the prior approval of the
holders of not less than 66 2/3% in liquidation amount of the outstanding
Preferred Securities issued by the applicable Heftel Trust. The manner of
obtaining any such approval of holders of such Preferred Securities will be set
forth in an accompanying Prospectus Supplement. All guarantees and agreements
contained in a Guarantee shall bind the successors, assignees, receivers,
trustees and representatives of the Company and shall inure to the benefit of
the holders of the Preferred Securities of the applicable Heftel Trust then
outstanding. Except in connection with a consolidation, merger, conveyance, or
transfer of assets involving the Company that is permitted under the Junior
Subordinated Indenture, the Company may not assign its obligations under any
Guarantee.
 
TERMINATION OF THE GUARANTEES
 
    Each Guarantee will terminate and be of no further force and effect as to
the Preferred Securities issued by the applicable Heftel Trust upon full payment
of the redemption price of all Preferred Securities of such Heftel Trust, or
upon distribution of the Junior Subordinated Debt Securities to the holders of
the Preferred Securities of such Heftel Trust in exchange for all the Preferred
Securities issued by such Heftel Trust, or upon full payment of the amounts
payable upon liquidation of such Heftel Trust. Notwithstanding the foregoing,
each Guarantee will continue to be effective or will be reinstated, as the case
may be, if at any time any holder of Preferred Securities issued by the
applicable Heftel Trust must restore payment of any sums paid under such
Preferred Securities or such Guarantee.
 
                                      A-34
<PAGE>
STATUS OF THE GUARANTEES
 
    The Company's obligations under each Guarantee to make the Guarantee
Payments will constitute an unsecured obligation of the Company and will rank
(i) subordinate and junior in right of payment to all other indebtedness,
liabilities and obligations of the Company and any guarantees, endorsements or
other contingent obligations of the Company in respect of such indebtedness,
liabilities or obligations, including the Junior Subordinated Debt Securities,
except those made pari passu or subordinate by their terms, and (ii) senior to
all capital stock now or hereafter issued by the Company and to any guarantee
now or hereafter entered into by the Company in respect of any of its capital
stock. The Company's obligations under each Guarantee will rank pari passu with
each other Guarantee. Because the Company is a holding company, the Company's
obligations under each Guarantee are also effectively subordinated to all
existing and future liabilities, including trade payables, of the Company's
subsidiaries, except to the extent that the Company is a creditor of the
subsidiaries recognized as such. Each Declaration provides that each holder of
Preferred Securities issued by the applicable Heftel Trust, by acceptance
thereof, agrees to the subordination provisions and other terms of the related
Guarantee.
 
    Each Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the Company to enforce its rights under such Guarantee without first instituting
a legal proceeding against any other person or entity). Each Guarantee will be
deposited with the Guarantee Trustee, to be held for the benefit of the holders
of the Preferred Securities issued by the applicable Heftel Trust. The Guarantee
Trustee shall enforce such Guarantee on behalf of the holders of such Preferred
Securities. The holders of not less than a majority in aggregate liquidation
amount of the Preferred Securities issued by the applicable Heftel Trust have
the right to direct the time, method and place of conducting any proceeding for
any remedy available in respect of the related Guarantee, including the giving
of directions to the Guarantee Trustee. If the Guarantee Trustee fails to
enforce a Guarantee as above provided, any holder of Preferred Securities issued
by the applicable Heftel Trust may institute a legal proceeding directly against
the Company to enforce its rights under such Guarantee, without first
instituting a legal proceeding against the applicable Heftel Trust, or any other
person or entity. Notwithstanding the foregoing, if the Company has failed to
make a Guarantee Payment, a holder of Preferred Securities may directly
institute a proceeding against the Company for enforcement of such holder's
right to receive payment under the Guarantee. The Company waives any right or
remedy to require that any action be brought first against a Heftel Trust or any
other person or entity before proceeding directly against the Company.
 
MISCELLANEOUS
 
    The Company will be required to provide annually to the Guarantee Trustee a
statement as to the performance by the Company of certain of its obligations
under each Guarantee and as to any default in such performance. The Company is
required to file annually with the Guarantee Trustee an officer's certificate as
to the Company's compliance with all conditions to be complied with by it under
each Guarantee.
 
    The Guarantee Trustee, prior to the occurrence of a default, undertakes to
perform only such duties as are specifically set forth in the applicable
Guarantee and, after default with respect to a Guarantee, shall exercise the
same degree of care as a prudent individual would exercise under the
circumstances in the conduct of his or her own affairs. Subject to such
provision, the Guarantee Trustee is under no obligation to exercise any of the
powers vested in it by a Preferred Securities Guarantee at the request of any
holder of Preferred Securities unless it is offered reasonable security and
indemnity against the costs, expenses and liabilities that might be incurred
thereby.

<PAGE>
                                 ERISA MATTERS
 
    The Company and its affiliates may each be considered a "party in interest"
(within the meaning of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA")) or a "disqualified person" (within the meaning of Section
4975 of the Internal Revenue Code of 1986, as amended (the "Code")) with respect
to many employee benefit plans ("Plans") that are subject to ERISA. The purchase
of Offered Securities by a Plan that is subject to the fiduciary responsibility
provisions of ERISA or the prohibited transaction provisions of Section 4975 of
the Code (including individual retirement arrangements and other plans described
in Section 4975(e)(1) of the Code) and with respect to which the Company or any
affiliate of the Company is a service provider (or otherwise is a party in
interest or a disqualified person) may constitute or result in a prohibited
transaction under ERISA or Section 4975 of the Code, unless such Offered
Securities are acquired pursuant to and in accordance with an applicable
exemption. Any pension or other employee benefit plan proposing to acquire any
Offered Securities should consult with its counsel.
 
                              PLAN OF DISTRIBUTION
 
    The Company or the Heftel Trusts may sell the Offered Securities offered
hereby (i) through underwriters or dealers, (ii) through agents, (iii) directly
to purchasers, or (iv) through a combination of any such methods of sale. Any
such underwriter, dealer or agent may be deemed to be an underwriter within the
meaning of the Securities Act. Certain Offered Securities may be distributed in
a concurrent offering by the Company and one or more selling stockholders of the
Company. The Prospectus Supplement relating to the Offered Securities will set
forth their offering terms, including the name or names of any underwriters,
dealers or agents, the purchase price of the Offered Securities and the proceeds
to the Company or the Heftel Trusts from such sale, any underwriting discounts,
commissions and other items constituting compensation to underwriters, dealers

resold from time to time in one or more transactions, at a fixed price or
prices, which may be changed, or at market prices prevailing at the time of

underwriters and other persons soliciting such contracts will have no
responsibility for the validity or performance of any such contracts.
 
    Underwriters, dealers and agents may be entitled under agreements entered
into with the Company or the Heftel Trusts to indemnification by the Company or
the Heftel Trusts against certain civil liabilities, including liabilities under
the Securities Act, or to contribution by the Company or the Heftel Trusts to
payments they may be required to make in respect thereof. The terms and

    Each series of Offered Securities offered by the Company or the Heftel

Securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for any Offered Securities.
 
    Any underwriter may engage in stabilizing and syndicate covering
transactions in accordance with Rule 104 under the Exchange Act. Rule 104
permits stabilizing bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. The underwriters may
over-allot shares of the Common Stock in connection with an offering of Common
Stock, thereby creating a short position in the underwriters' account. Syndicate
covering transactions involve purchases of the Debt Securities or Junior
Subordinated Debt Securities in the open market after the distribution has been
completed in order to cover syndicate short positions. Stabilizing and syndicate
covering transactions may cause the price of the Debt Securities or Junior
Subordinated Debt Securities to be higher than it would otherwise be in the
absence of such transactions. These transactions, if commenced, may be
discontinued at any time.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED HEREIN BY
REFERENCE IN THIS PROSPECTUS, AS WELL AS ANY INFORMATION OR RISK FACTORS
CONTAINED IN A PROSPECTUS SUPPLEMENT RELATED TO THE CLASS A COMMON STOCK OFFERED
BY THIS PROSPECTUS, THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN
EVALUATING AN INVESTMENT IN THE CLASS A COMMON STOCK OFFERED BY THIS PROSPECTUS.
 
CONCENTRATION OF CASH FLOW FROM LOS ANGELES STATIONS
 
    Broadcast cash flow generated by the Company's Los Angeles stations accounts
for a large percentage of the Company's broadcast cash flow. Increased
competition for advertising dollars with other radio stations and communications
media in the Los Angeles metropolitan area, both generally and relative to the
broadcasting industry, increased competition from a new format competitor, and
other competitive and economic factors could cause a decline in revenue from the
Company's Los Angeles stations. A significant decline in the revenue of the Los
Angeles stations could have a material adverse effect on the Company's overall
results of operations and broadcast cash flow. See "--Competition."
 
FINANCIAL LEVERAGE; PLEDGE OF ASSETS
 
    The Company has borrowed and expects to continue borrowing to finance
acquisitions of radio stations and for other corporate purposes. Future
acquisitions of radio stations effected in connection with the implementation of
the Company's acquisition strategy are expected to be financed from increased
borrowings under its credit facility, other debt or equity financings and cash
flow from operations. See "--Growth through Future Acquisitions; Capital
Requirements."
 
    Stock and partnership interests of the Company's subsidiaries are pledged to
secure the Company's obligations under the Credit Agreement dated February 14,
1997, among the Company, the lenders signatory thereto and The Chase Manhattan
Bank., as administrative agent (the "Credit Agreement"). The Credit Agreement
contains various financial and operational covenants and other restrictions with
which the Company must comply, including limitations on capital expenditures and
the incurrence of additional indebtedness, prohibitions on the payment of cash
dividends and the redemption or repurchase of capital stock of the Company and
restrictions on the use of borrowings. The Credit Agreement may adversely affect
the Company's ability to pursue its strategy of further growth through
acquisitions.
 
GROWTH THROUGH FUTURE ACQUISITIONS; CAPITAL REQUIREMENTS
 
    One of the Company's growth strategies is to acquire additional radio
stations. There can be no assurance that the Company will be able to complete
any further acquisitions or, if completed, that such acquired radio stations can
be operated profitably or assimilated into the Company's business structure in
the manner desired by the Company's management. Entities acquired by the Company
may have liabilities for which the Company may become responsible. Additional
debt or equity financing may be required in order to complete future
acquisitions, and there can be no assurance that the Company will be able to
obtain such financing. The Company may acquire stations which have not
previously broadcast Spanish language programming. In converting these stations
to a Spanish language format, revenue and cash flow from station operations
generated prior to the conversion may not be indicative of future financial
performance. Furthermore, such conversions may result in significant operating
losses for an undetermined period of time.
 
GOVERNMENT REGULATION OF RADIO BROADCASTING INDUSTRY
 
    Pursuant to the Communications Act of 1934 (the "Communications Act"), the
domestic broadcasting industry is subject to extensive federal regulation which,
among other things, requires approval by the Federal Communications Commission
(the "FCC") for the issuance, renewal, transfer and assignment of broadcasting
station operating licenses and limits the number of broadcasting properties the
Company may
 
                                      B-7
<PAGE>
acquire in any market. The Telecommunications Act of 1996 (the "1996 Act"),
which became law on February 8, 1996, creates significant new opportunities for
broadcasting companies but also creates uncertainties as to how the FCC and the
courts will enforce and interpret the 1996 Act.
 
    The Company's business will continue to be dependent upon acquiring and
maintaining broadcasting licenses issued by the FCC, which are currently issued
for a term of eight years. There can be no assurance that pending or future
renewal applications will be approved, or that renewals will not include
conditions or qualifications that could adversely affect the Company's
operations. Moreover, governmental regulations and policies may change over time
and there can be no assurance that such changes would not have a material
adverse impact upon the Company's business, financial position and results of
operations.
 
    In addition, the Federal Trade Commission (the "FTC") and the Department of
Justice--Antitrust Division (the "Antitrust Division") have been reviewing media
acquisitions, including radio station acquisitions, to determine whether they
are in compliance with antitrust laws, even in situations in which the
acquisition conforms with the ownership restrictions of the 1996 Act. See
"--Antitrust Matters."
 
ANTITRUST MATTERS
 
    An important element of the Company's growth strategy involves the
acquisition of additional radio stations, most of which are likely to require
preacquisition antitrust review by the FTC and the Antitrust Division. Following
passage of the 1996 Act, the Antitrust Division has become more aggressive in
reviewing proposed acquisitions of radio stations and radio station networks,
particularly in instances where the proposed acquirer already owns one or more
radio stations in a particular market and the acquisition involves another radio
station in the same market. In reviewing proposed acquisitions, the Antitrust
Division has also mentioned that it may consider the concentration of radio
stations the proposed acquirer owns within a particular station format in each
market. In the past, the Antitrust Division has obtained consent decrees
requiring an acquirer to dispose of at least one radio station in a particular
market where the acquisition otherwise would have resulted in a concentration of
market share by the acquirer. There can be no assurance that the Antitrust
Division or the FTC will not seek to bar the Company from acquiring additional
radio stations in a market where the Company's existing stations already have a
significant market share of the overall radio market or the Spanish-language
market segment.
 
COMPETITION
 
    Broadcasting is a highly competitive business. The Company's radio stations
compete for audiences and advertising revenues with other radio stations of all
formats, as well as with other media, such as newspapers, magazines, television,
cable television, outdoor advertising and direct mail, within their respective
markets. Audience ratings and market shares are subject to change and any
adverse change in a particular market could have a material adverse effect on
the revenue of stations located in that market. Future operations are further
subject to many variables which could have an adverse effect upon the Company's
financial performance. These variables include: economic conditions, both
general and relative to the broadcasting industry; shifts in population and
other demographics; the level of competition for advertising dollars with other
radio stations and other entertainment and communications media; fluctuations in
operating costs; technological changes and innovations; changes in labor
conditions; and changes in governmental regulations and policies and actions of
federal regulatory bodies, including the FCC, the FTC, and the Antitrust
Division. Although the Company believes that each of its stations is or will be
able to compete effectively in its respective market, there can be no assurance
that any such station will be able to maintain or increase its current audience
ratings and advertising revenues. Radio stations can quickly change formats. Any
radio station could shift its format to duplicate the format of any of the
Company's stations. If a station converted its programming to a format similar
to that of a station owned by the Company, the ratings and broadcast cash flow
of the Company's station could be adversely affected.
 
                                      B-8

NEW TECHNOLOGIES
 
    The FCC is considering ways to introduce new technologies to the radio
broadcast industry, including satellite and terrestrial delivery of digital
audio broadcasting and the standardization of available technologies which
significantly enhance the sound quality of AM broadcasts. The Company is unable
to predict the effect any such new technology will have on the Company's
financial condition or results of operations. In addition, cable television
operators are introducing a new service commonly referred to as "cable radio"
which provides cable television subscribers with several high-quality channels
of music, news and other information, and direct satellite broadcast television
companies are supplying subscribers with several high quality music channels.
 
CONTROL BY CERTAIN STOCKHOLDERS
 
    Collectively, the Tichenor Family (defined below), Clear Channel
Communications, Inc. ("Clear Channel"), and Ronald Baron own approximately 59%
of the Common Stock.
 
    CONTROL BY THE TICHENOR FAMILY
 
    McHenry T. Tichenor, Jr., the Company's Chief Executive Officer, McHenry T.
Tichenor, Sr., David T. Tichenor, Warren W. Tichenor, William E. Tichenor and
Jean T. Russell (collectively, the "Tichenor Family") are parties to a Voting
Agreement with one another, dated as of July 1, 1996 (the "Voting Agreement").
As of December 9, 1997, the Tichenor Family had voting control over
approximately 26.9% of the shares of Class A Common Stock. In addition, the
Company's Board of Directors is comprised entirely of members of the Tichenor
Family or their designees. This enables the Tichenor Family to exert significant
influence over all of the Company's management decisions. Such ownership and
control by the Tichenor Family could have the effect of delaying or preventing a
change in control of the Company, thereby possibly having the effect of
depriving stockholders of the opportunity to receive a premium for their shares.
Such ownership and control could also have the effect of making the Company less
attractive to a potential acquirer and could result in holders of Class A Common
Stock receiving less consideration upon a sale of their shares than might
otherwise be available in the event of a takeover attempt.
 
    RELATIONSHIP BETWEEN THE COMPANY AND RONALD BARON
 
    As of February 5, 1997, Ronald Baron reported beneficial ownership of an
aggregate of 3,758,600 shares of Class A Common Stock through Baron Investment
Partners, L.P., Baron Asset Fund, Baron Growth and Income Fund, and Baron
Capital Management, Inc., each of which are controlled by Mr. Baron. Based on
Mr. Baron's Exchange Act filings, as of December 8, 1997, the shares were
acquired in the ordinary course of business and were not acquired for the
purpose of changing or influencing the control of the Company and were not
acquired in connection with or as a participant in any transaction having such
purposes or effect.
 
    RELATIONSHIP BETWEEN THE COMPANY AND CLEAR CHANNEL
 
    OWNERSHIP OF CLASS B COMMON STOCK.  As of October 31, 1997, Clear Channel
Communications, Inc., and its subsidiaries ("Clear Channel") owned no shares of
Class A Common Stock and thus was not entitled to vote in the election of the
Company's directors. However, Clear Channel owned all of the outstanding shares
of the Company's Class B Common Stock, which accounted for approximately a 32%
interest in the Common Stock of the Company. As long as Clear Channel and its
affiliates own at least 20% of the Company's Common Stock, Clear Channel will
have a class vote on certain matters, including the sale of all or substantially
all of the assets of the Company, any merger or consolidation involving the
Company where the stockholders of the Company immediately prior to the
transaction would not own at least 50% of the capital stock of the surviving
entity, any reclassification, capitalization, dissolution, liquidation or
winding up of the Company, the issuance of any shares of Preferred Stock by the
Company,
 
                                      B-9
<PAGE>
the amendment of the Company's Restated Certificate of Incorporation in a manner
that adversely affects the rights of the holders of Class B Common Stock, the
declaration or payment of any non-cash dividends on the Company's Common Stock,
or any amendment to the Company's Certificate of Incorporation concerning the
Company's capital stock. Furthermore, shares of Class B Common Stock are
convertible into shares of Class A Common Stock, at the holder's option, subject
to any necessary FCC consents. These provisions relating to the Class B Common
Stock could have the effect of delaying or preventing a change in control of the
Company, thereby possibly having the effect of depriving stockholders of the
opportunity to receive a premium for their shares. Such provisions could also
have the effect of making the Company less attractive to a potential acquirer
and could result in holders of Class A Common Stock receiving less consideration
upon a sale of their shares than might otherwise be available in the event of a
takeover attempt. See "Description of Capital Stock."
 
    POTENTIAL CONFLICTS OF INTEREST.  The nature of the respective businesses of
the Company and Clear Channel gives rise to potential conflicts of interest
between the two companies. The Company and Clear Channel are each engaged in the
radio broadcasting business in certain markets, and as a result, they are
competing with each other for advertising revenues. According to Clear Channel's
Securities Act filings, as of June 30, 1997, Clear Channel owned or programmed
109 radio stations in 27 domestic markets, as well as radio stations in a number
of foreign countries. Clear Channel also owned or programmed 18 television
stations and was one of the largest domestic outdoor advertising companies based
on its total inventory of advertising display faces. Clear Channel's television
and outdoor advertising operations may also be deemed to compete with the
Company's business. In addition, conflicts could arise with respect to
transactions involving the purchase or sale of radio broadcasting companies,
particularly Spanish language radio broadcasting companies, the issuance of
additional shares of Common Stock, or the payment of dividends by the Company.
 
    Although Clear Channel does not currently engage in the domestic Spanish
language radio broadcasting business, other than through its ownership of shares
in the Company, circumstances could arise that would cause Clear Channel to
engage in the domestic Spanish language broadcasting business. There can be no
assurance that Clear Channel will not engage in the domestic Spanish language
broadcasting business. In addition, as part of Clear Channel's overall
acquisition strategy, Clear Channel may from time to time acquire Spanish
language radio broadcasting companies individually or as part of a larger group
and thereafter engage in the Spanish language radio broadcasting business. Such
activities could directly or indirectly compete with the Company's business. In
addition, Clear Channel may from time to time make international acquisitions of
or investments in companies engaged in the Spanish language radio broadcasting
business outside the United States and the Company and Clear Channel may compete
for such acquisition or investment opportunities.

                          DESCRIPTION OF CAPITAL STOCK
 
    The Company's authorized capital stock consists of 50,000,000 shares of
Class A Common Stock, $.001 par value, 50,000,000 shares of Class B Common
Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001 par
value. As of December 9, 1997, 29,978,748 shares of Class A Common Stock were
outstanding, 14,156,470 shares of Class B Common Stock were outstanding, and no
shares of Preferred Stock were outstanding.
 
COMMON STOCK
 
    The rights of holders of shares of Class A and Class B Common Stock are
identical except for voting rights and certain rights of the Class B Common
Stock relating to its conversion to Class A Common Stock. Holders of Class A and
Class B Common Stock are entitled to ratably receive dividends, if any, as may
be declared from time to time by the Board of Directors from funds legally
available therefor, subject to the payment of any preferential dividends
declared with respect to any Preferred Stock that from time to time may be
outstanding. Upon liquidation, dissolution or winding up of the Company, holders
of Common Stock are entitled to share ratably in any assets available for
distribution to stockholders after payment of all obligations of the Company,
subject to the rights to receive preferential distributions of the holders of
any shares of Preferred Stock then outstanding.
 
    Holders of Class A and Class B Common Stock do not have cumulative voting
rights or preemptive or other rights to acquire or subscribe to additional,
unissued or treasury shares. The shares of Class A and Class B Common Stock
currently outstanding are, and the shares of Class A Common Stock offered hereby
will be, upon issuance thereof, validly issued, fully paid and nonassessable.
 
    CLASS A COMMON STOCK
 
    Holders of shares of Class A Common Stock are entitled to one vote per share
on all matters submitted to a vote of the stockholders. As of December 9, 1997,
the Tichenor Family owned approximately 18.2% of the Common Stock then
outstanding and approximately 26.9% of Class A Common Stock then outstanding.
 
    CLASS B COMMON STOCK
 
    Holders of the Class B Common Stock will, in certain circumstances, have
certain voting rights, with each share of Class B Common Stock being entitled to
one vote. Specifically, so long as Clear Channel and its affiliates own at least
20% of the Common Stock then outstanding, the Company will not be able to, and
will not be able to permit any subsidiary to, without the vote or consent by the
holders of a majority of the Class B Common Stock voting as a single class, take
any of the following actions: (i) effect the sale, lease or other transfer of
all or substantially all of the assets of the Company, or any merger or
consolidation involving the Company where the stockholders of the Company
immediately prior to such transaction would not own at least 50% of the capital
stock of the surviving entity, or any reclassification, recapitalization,
dissolution, liquidation or winding up of the Company; (ii) authorize, issue or
obligate itself to issue any shares of Preferred Stock; (iii) make or permit any
amendment to the Company's certificate of incorporation that adversely affects
the rights of the holders of Class B Common Stock; (iv) declare or pay any
non-cash dividends on or make any other non-cash distribution on the Company's
Common Stock; or (v) make or permit any amendment or modification to the
Company's certificate of incorporation concerning the Company's capital stock.
 
    The Company's Certificate of Incorporation provides that only Clear Channel
and its affiliates may own shares of Class B Common Stock. The outstanding Class
B Common Stock will convert into Class A Common Stock automatically upon sale,
gift or other transfer to a person or entity other than Clear Channel or an
affiliate of Clear Channel. Each share of the Class B Common Stock will also be
convertible into Class A Common Stock at the option of its holder subject to
necessary FCC consents. In addition,
 
                                      B-12
<PAGE>
Clear Channel may convert shares of Class A Common Stock held by it into shares
of Class B Common Stock at its option.
 
    As of December 9, 1997, Clear Channel owned approximately 32% of the Common
Stock then outstanding and all 14,156,470 shares of Class B Common Stock.
 
    Upon consummation of the Company's merger with Tichenor Media System, Inc.,
on February 14, 1997 (the "Tichenor Merger"), the FCC's cross-interest policy
prohibited Clear Channel from owning more than 33.3% of the total outstanding
Common Stock of the Company. The FCC's cross interest policy bars a party which
holds an attributable interest in one or more radio stations in a market from
having a "meaningful relationship" with another radio station in that market. A
"meaningful relationship" is construed by the FCC to include a non-voting equity
position in excess of 33.3% of the total outstanding Common Stock.
 
PREFERRED STOCK
 
    Upon obtaining the consent of the holders of Class B Common Stock in the
circumstances described above, the Board of Directors has the authority to issue
shares of Preferred Stock, in one or more series, and to fix the rights,
preferences, privileges, and qualifications thereof without any further vote or
action by the stockholders. The issuance of Preferred Stock could decrease the
amount of earnings and assets available for distribution to holders of Class A
and Class B Common Stock, and adversely affect the rights and powers, including
voting rights, of such holders and may have the effect of delaying, deferring or
preventing a change in control of the Company.
 
REGISTRATION RIGHTS AGREEMENTS; STOCKHOLDERS AGREEMENT; VOTING AGREEMENT
 
    In connection with Tichenor Merger, the Company entered into a Registration
Rights Agreement, dated February 14, 1997, by and among the Company and the
various stockholders named therein (the "Registration Rights Agreement"),
pursuant to which the Company granted certain demand and "piggyback"
registration rights to certain former Tichenor stockholders who own, as of
December 9, 1997, an aggregate of 8,608,338 shares of Class A Common Stock
(collectively, the "Major Tichenor Stockholders"). The Company also entered into
a Registration Rights Agreement, dated February 14, 1997, between the Company
and Clear Channel (the "Clear Channel Registration Rights Agreement"), pursuant
to which the Company granted certain demand and piggyback registration rights to
Clear Channel with respect to any shares of Class A Common Stock that may be
held from time to time by Clear Channel following the Tichenor Merger. Upon
consummation of the Tichenor Merger, Clear Channel and certain of the Major
Tichenor Stockholders also entered into a Stockholders Agreement (the
"Stockholders Agreement") with the Company whereby such stockholders agreed to
certain restrictions on the transfer of their shares of Class A Common Stock of
the Company and granted certain rights of first refusal and "tag-along" rights
with respect to certain sales of such shares. In addition, the members of the
Tichenor Family are parties to the Voting Agreement with one another pursuant to
which the shares of Class A Common Stock held by them shall be voted in
accordance with the instructions of the holders of a majority of such shares.
 
CERTAIN ANTI-TAKEOVER EFFECTS OF CHARTER AND DELAWARE LAW
 
    Certain provisions of the Company's Certificate of Incorporation and the
Delaware General Corporation Law ("DGCL") may have the effect of impeding the
acquisition of control of the Company by means of a tender offer, proxy fight,
open market purchases or otherwise.
 
    As provided in the Company's Certificate of Incorporation, holders of Class
B Common Stock will have the right to vote separately as a class on certain
matters, including a merger of the Company or sale of all or substantially all
of its assets. In addition, shares of Class B Common Stock are convertible into
shares of Class A Common Stock at the holder's option, subject to the receipt of
applicable regulatory approvals.
 
                                      B-13
<PAGE>
    Section 203 of the DGCL restricts a wide range of transactions ("business
combinations") between a corporation and an interested stockholder. An
"interested stockholder" is, generally, any person who beneficially owns,
directly or indirectly, 15% or more of the corporation's outstanding voting
stock. Business combinations are broadly defined to include (i) mergers or
consolidations with, (ii) sales or other dispositions of more than 10% of the
corporation's assets to, (iii) certain transactions which would result in
increasing the proportionate share of stock of the corporation or any subsidiary
owned by, or (iv) receipt of the benefit (other than proportionately as a
stockholder) or any loans, advances or other financial benefits by, an
interested stockholder. Section 203 provides that an interested stockholder may
not engage in a business combination with a corporation for a period of three
years from the time of becoming an interested stockholder unless (i) the board
of directors approved either the business combination or the transaction which
resulted in the person becoming an interested stockholder prior to the time such
person became an interested stockholder; (ii) upon consummation of the
transaction which resulted in the person becoming an interested stockholder,
that person owned at least 85% of the corporation's voting stock (excluding
shares owned by persons who are officers and also directors and shares owned by
certain employee stock plans); or (iii) the business combination is approved by
the board of directors and authorized by the affirmative vote of at least
66 2/3% of the outstanding voting stock not owned by the interested stockholder.
 
FOREIGN OWNERSHIP
 
    The Company's Certificate of Incorporation restricts the ownership and
voting of the Company's capital stock, including its Class A Common Stock, in
accordance with the Communications Act and the rules of the FCC to prohibit
ownership of more than 25% of the Company's outstanding capital stock (or
control of more than 25% of the voting power it represents) by or for the
account of aliens, foreign governments, or non-U.S. corporations or corporations
otherwise subject to control by such persons or entities. The Restated
Certificate of Incorporation also prohibits any transfer of the Company's
capital stock which would cause the Company to violate this prohibition. In
addition, the Restated Certificate of Incorporation authorizes the Company's
Board of Directors to adopt such provisions as it deems necessary to enforce
these prohibitions.
 
                              PLAN OF DISTRIBUTION
 
    The Shares may be sold or distributed from time to time by the Selling
Stockholders, or by pledgees, donees or transferees of, or other successors in
interest to, the Selling Stockholders, directly to one or more purchasers
(including pledgees) or through brokers, dealers or underwriters who may act
solely as agents or may acquire Shares as principals, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices, or at fixed prices, which may be changed. The
distribution of the Shares may be effected by one or more of the following
methods: (i) ordinary brokers' transactions, which may include long or short
sales; (ii) transactions involving cross or block trades or otherwise on the
Nasdaq National Market or other stock exchange on which the Class A Common Stock
may be listed from time to time; (iii) purchases by brokers, dealers or
underwriters as principals and resale by such purchasers for their own accounts
pursuant to this Prospectus; (iv) "at the market" to or through market makers or
into an existing market for the Class A Common Stock; (v) in other ways not
involving market makers or established trading markets, including direct sales
to purchasers or sales effected through agents; (vi) through transactions in
options, swaps or other derivatives (whether exchange-listed or otherwise); or
(vii) any combination of the foregoing, or by any other legally available means.
The distribution of the Shares may be made through the methods set forth above
in a concurrent offering by the Company and one or more of the Selling
Stockholders. In addition, the Selling Stockholders or their successors in
interest may enter into hedging transactions with broker-dealers who may engage
in short sales of Class A Common Stock in the course of hedging the positions
they assume with the Selling Stockholders. The Selling Stockholders or their
successors in interest may also enter into option or other
 
                                      B-14
<PAGE>
transactions with broker-dealers that require the delivery to such
broker-dealers of the Shares, which Shares may be resold thereafter pursuant to
this Prospectus.
 
    Brokers, dealers, underwriters or agents participating in the distribution
of the Shares as agent may receive compensation in the form of discounts,
concessions or commissions from the Selling Stockholders (and, if they act as
agent for the purchaser of such Shares, from such purchaser). Such discounts,
concessions or commissions as to a particular broker, dealer, underwriter or
agent might be greater or less than those customary in the type of transaction
involved.
 
    Any underwriter may engage in stabilizing transactions in accordance with
Rule 104 under the Exchange Act. Rule 104 permits stabilizing bids to purchase
the underlying security so long as the stabilizing bids do not exceed a
specified maximum. The underwriters may over-allot shares of the class A Common
Stock in connection with an offering of Class A Common Stock , thereby creating
a short position in the underwriters' account. These transactions, if commenced,
may be discontinued at any time.
 
    The Selling Stockholders and any brokers, dealers, underwriters or agents
that participate in the distribution of the Shares may be deemed to be
"underwriters" within the meaning of the Securities Act, and any discounts,
commissions or concessions received by any such persons might be deemed to be
underwriting discounts and commissions under the Securities Act. Neither the
Company nor the Selling Stockholders can presently estimate the amount of such
compensation. Other than the Stockholders Agreement, the Registration Rights
Agreement, the Clear Channel Registration Rights Agreement, and the Voting
Agreement, the Company knows of no existing arrangements between any Selling
Stockholder and any other stockholder, broker, dealer, underwriter or agent
relating to the sale or distribution of the Shares.
 
    To the extent required, the Company will file, during any period in which
offers or sales are being made, a supplement to this Prospectus which sets
forth, with respect to a particular offering, the specific number of Shares to
be sold, the name of the selling stockholder, the sales price, the name of any
participating broker, dealer, underwriter or agent, any applicable commission or
discount and any other material information with respect to the plan of
distribution not previously disclosed.
 
    The Company will not receive any of the proceeds from the sale of the Shares
offered hereby. Pursuant to the Registration Rights Agreement, the Company will
pay substantially all of the expenses incident to this offering of the Shares by
the Selling Stockholders to the public other than commissions and discounts of
brokers, dealers, underwriters or agents. The Company has agreed to indemnify
the Selling Stockholders and certain related persons against certain
liabilities, including certain liabilities under the Securities Act.
 
    In order to comply with certain states' securities laws, if applicable, the
Shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In addition, in certain states the Class A Common Stock may
not be sold unless the Class A Common Stock has been registered or qualified for
sale in such state or an exemption from registration or qualification is
available and is satisfied.
 
                                 LEGAL MATTERS
 
    The validity of the shares of Class A Common Stock offered hereby has been
passed upon for the Company by its special counsel, Akin, Gump, Strauss, Hauer &
Feld, L.L.P. (a partnership including professional corporations), San Antonio,
Texas.
