PROSPECTUS SUPPLEMENT
 
                                     [LOGO]
(TO PROSPECTUS DATED JANUARY 21, 1998)
 
                                     [LOGO]
                     LIQUID YIELD OPTION-TM- NOTES DUE 2018
                              (ZERO COUPON-SENIOR)
                          ---------------------------
 
    The issue price of each Liquid Yield Option-TM- Note ("LYON"-TM-) to be
issued by Jacor Communications, Inc. ("Jacor") will be $     (      % of
principal amount at maturity) (the "Issue Price") and there will be no periodic
payments of interest. The LYONs will mature on February   , 2018. The Issue
Price of each LYON represents a yield to maturity of     % per annum (computed
on a semi-annual bond equivalent basis) calculated from February   , 1998. The
LYONs will be senior unsecured general obligations of Jacor, ranking senior to
any future unsecured and unsubordinated indebtedness.
 
    The LYONs are being issued to fund, in part, the acquisition of 17 radio
stations from Nationwide Communications, Inc. and its affiliated entities
("Nationwide"). Alternatively and pending such uses, Jacor intends to use the
net proceeds from this LYONs offering (the "Offering") for general corporate
purposes, including the repayment in part of outstanding indebtedness and for
other acquisitions. See "Use of Proceeds." Concurrently with this Offering,
Jacor is offering approximately 3,800,000 shares of Jacor common stock, $.01 par
value per share (the "Common Stock Offering"), and Jacor Communications Company,
a wholly-owned subsidiary of Jacor ("JCC"), is offering $100.0 million aggregate
principal amount of its    % Senior Subordinated Notes due 2010 (the "Notes
Offering" and, together with the Common Stock Offering, the "Related
Offerings"). Consummation of this Offering is subject to consummation of the
Related Offerings. Consummation of this Offering is not subject to consummation
of the Nationwide Acquisition (as defined herein) or any of the other Pending
Transactions (as defined herein). See "Transactions" and "Use of Proceeds."
 
    On a pro forma basis as of September 30, 1997 after giving effect to this
Offering, the Related Offerings, the application of the net proceeds therefrom,
the consummation of the Nationwide Acquisition, the other Pending Transactions
and any other transaction consummated after September 30, 1997, Jacor and its
subsidiaries would have had $1.2 billion of indebtedness outstanding that would
have been effectively senior to the LYONs.
 
    Each LYON will be convertible at the option of the Holder at any time on or
prior to maturity, unless previously redeemed or otherwise purchased, into
common stock of Jacor (the "Common Stock") at a conversion rate of      shares
per LYON (the "Conversion Rate"). The Conversion Rate will not be adjusted for
accrued Original Issue Discount (as defined herein) but will be subject to
adjustment upon the occurrence of certain events affecting the Common Stock.
Upon conversion, the Holder will not receive any cash payment representing
accrued Original Issue Discount; such accrued Original Issue Discount will be
deemed paid by the Common Stock received on conversion. See "Description of
LYONs--Conversion Rights." On January 20, 1998, the last reported sale price of
the Common Stock on the Nasdaq Stock Market's National Market (the "Nasdaq
National Market") was $53 1/4 per share. Application will be made to have the
LYONs approved for listing, subject to official notice of issuance, on the
Nasdaq Stock Market's SmallCap Market under the symbol "        ."
 
    The LYONs will be purchased by Jacor, at the option of the Holder, on
February    , 2003, February   , 2008 and February   , 2013 (each, a "Purchase
Date") for a Purchase Price per LYON of $      , $      and $      (Issue Price
plus accrued Original Issue Discount to each such date), respectively. Jacor, at
its option, may elect to pay the Purchase Price on any Purchase Date in cash or
shares of Common Stock at the market value or in any combination thereof. See
"Description of LYONs--Purchase of LYONs at the Option of the Holder." In
addition, as of 35 business days after the occurrence of any Change in Control
of Jacor occurring on or prior to February    , 2003, LYONs will be purchased
for cash by Jacor, at the option of the Holder, for a Change in Control Purchase
Price equal to the Issue Price plus accrued Original Issue Discount to the date
set for such purchase. There can be no assurance that Jacor would have
sufficient funds to pay the Change in Control Purchase Price. See "Description
of LYONs--Change in Control Permits Purchase of LYONs at the Option of the
Holder."
 
    The LYONs are not redeemable by Jacor prior to February   , 2003. On and
after that date, the LYONs are redeemable for cash at any time at the option of
Jacor, in whole or in part, at a Redemption Price equal to the Issue Price plus
accrued Original Issue Discount to the date of redemption. See "Description of
LYONs--Redemption of LYONs at the Option of Jacor." At final maturity, Jacor is
required to pay cash in satisfaction of the LYONs.

Considerations."

                                  THE COMPANY
 
    Jacor, upon consummation of the Pending Transactions, will be the second
largest radio group in the United States in terms of number of radio stations
and will be the fourth largest radio group in the nation as measured by revenue
and is the country's third largest provider of syndicated radio programming. The
Company will own and/or operate 186 radio stations and one television station in
48 broadcast areas across the United States upon consummation of the Pending
Transactions. The Company's broadcast areas, as a group, are among the most
attractive in the country, demonstrating radio revenue growth in excess of the
radio industry average over the last five years. Jacor also produces more than
50 syndicated programs and services for more than 4,000 radio stations, which
programs include RUSH LIMBAUGH, THE DR. LAURA SCHLESSINGER SHOW and DR. DEAN
EDELL, the top three rated radio programs in the United States. In 1996, the
Company would have been number one or number two in terms of radio revenue rank
in 25 of its 35 ranked broadcast areas. On a pro forma basis, the Company would
have had net revenue and broadcast cash flow of $682.2 million and $224.2
million, respectively, for the latest twelve months ("LTM") ended September 30,
1997.
 
                               BUSINESS STRATEGY
 
    Jacor's strategic objective is to maximize revenue and broadcast cash flow
by becoming the leading radio broadcaster in geographically diverse broadcast
areas and by leveraging its expertise in programming production, syndication and
distribution. Jacor intends to acquire individual radio stations, radio groups
and/or businesses that provide radio broadcasting services that strengthen its
strategic position in the radio industry and enhance its operating performance.
Specifically, Jacor's business strategy centers upon:
 
    BROADCAST AREA REVENUE LEADERSHIP.  Jacor strives to maximize its audience
ratings in each of its broadcast areas in order to capture the largest share of
the radio advertising revenue in that area and to attract advertising away from
other media. Jacor believes that the most effective way to capture a higher
percentage of advertising revenue is to operate multiple radio stations within a
broadcast area, tailoring each station's programming to deliver highly effective
access to a target demographic. In implementing its multi-station strategy,
Jacor utilizes its programming expertise over a broad range of radio formats to
create distinct station personalities within a broadcast area. Jacor further
enhances its ability to increase its revenues through a more complete coverage
of the listener base by being an industry leader in successfully operating AM
stations.
 
    DEVELOPMENT OF "STICK" PROPERTIES.  In addition to acquiring developed, cash
flow producing stations, Jacor also strategically acquires underdeveloped
"stick" properties (I.E., properties with insignificant ratings and/or little or
no positive broadcast cash flow). Jacor believes that acquisitions of
strategically located "stick" properties often provide greater potential for
revenue and broadcast cash flow growth than do
 
                                      S-3
<PAGE>
acquisitions of developed properties. Historically, Jacor has been able to
improve the ratings, revenue and broadcast cash flow of its "stick" properties
with increased marketing and focused programming that complements its existing
radio station formats and by leveraging the management expertise and operational
support of regional clusters. Additionally, Jacor increases the revenue and
broadcast cash flow of "stick" properties by encouraging advertisers to buy
advertising in a package with its more established stations. Jacor believes that
the Company's portfolio of 99 "stick" properties creates significant potential
for revenue and broadcast cash flow growth. For example, Jacor improved the
broadcast cash flow of the 47 "stick" properties it owned or operated as of May
1, 1997 from approximately $3.4 million in 1996 to approximately $9.7 million in
1997, an increase of approximately 185%.
 
    DEVELOPMENT OF REGIONAL CLUSTERS AROUND CORE BROADCAST AREAS.  Jacor
believes it can leverage its position as the leader in a core broadcast area to
create additional revenue and broadcast cash flow opportunities by building
regional multi-station clusters around Jacor's core broadcast areas. Utilizing
programming from its core broadcast areas, Jacor provides its regional clusters
with high quality programming which would not otherwise be economically viable
in such smaller broadcast areas, thereby spreading the costs associated with the
delivery of such programming across a greater number of stations. By improving
the ratings of its regional stations with such enhanced programming, Jacor
believes it can generate incremental revenue and broadcast cash flow. For
example, Jacor has utilized this strategy in the Denver, Colorado broadcast area
by acquiring stations in Casper and Cheyenne, Wyoming and Fort Collins/Greeley,
Colorado to develop a regional cluster.
 
    STRATEGIC ACQUISITIONS OF COMPLEMENTARY STATIONS.  Jacor focuses its
acquisition strategy on acquiring stations with powerful broadcast signals that
complement its existing portfolio and strengthen its overall competitive
position. By operating multiple stations within its broadcast areas, Jacor seeks
to position itself as the most efficient advertising medium in a geographic
location, providing advertisers with wide access to a variety of demographic
groups through a single purchase of advertising time. Through the acquisition of
additional stations within an existing broadcast area, Jacor spreads its fixed
costs over a larger base of stations and creates operating efficiencies enabling
it to generate higher broadcast cash flow. Jacor may enter additional broadcast
areas, domestic or international, through acquisitions of radio groups that have
multiple station platforms and/or through acquisitions of individual stations in
new locations where Jacor believes a revenue-leading position can be created.
 
    Since the enactment of the Telecommunications Act of 1996 on February 8,
1996, through December 31, 1997, Jacor has acquired or entered into binding
agreements to acquire 158 radio stations and two television stations, and
entered into an exclusive sales agency agreement to provide programming to and
sell air time for two radio stations located in Baja California, Mexico. The
aggregate consideration paid and to be paid for these transactions is
approximately $2.3 billion. In addition, Jacor has exchanged one of the
television stations and seven radio stations for 17 radio stations in
transactions valued in the aggregate at approximately $315.0 million.
 
    ACQUISITIONS OF BROADCAST RELATED BUSINESSES.  Jacor strengthens its
strategic position in the radio industry through the acquisition and operation
of businesses that provide services to radio broadcasting companies. In 1997,
Jacor significantly expanded its base of syndicated radio programming available
to both Jacor's radio stations and other broadcasting companies. Jacor acquired
for approximately $340.3 million, a leading producer and distributor of radio
programming research, two leading providers of syndicated talk radio
programming, a leading provider of satellite and network services for the radio
broadcasting industry and a leading provider of traffic reporting services in
the San Diego and Los Angeles, California broadcast areas.
 
    In addition to generating cash flow, these broadcast related services
enhance the Company's ability to (i) increase ratings for its existing stations,
(ii) transform "stick" properties into broadcast cash flow producing properties
and (iii) maintain long-term relationships with Jacor's on-air talent. For
example, Jacor increased the audience ratings of KEWS-AM in Portland, Oregon by
approximately 64% after adding the
 
                                      S-4
<PAGE>
RUSH LIMBAUGH show to that station's program line-up. By combining the national
reach of the Company's radio stations with the network sales forces acquired by
Jacor, the Company seeks to maximize the value of commercial broadcast inventory
that it can then resell to national advertisers. See "Broadcasting Related
Acquisitions." The Company also will benefit from the NSN Network Services (as
defined herein) distribution network acquired by Jacor in 1997, which network
will create efficiencies and lower costs related to the distribution of
programming among the Company's radio stations.
 
                              RECENT DEVELOPMENTS
 
    Jacor has entered into an asset purchase agreement with Nationwide to
acquire 17 radio stations for approximately $620.0 million. Upon consummation of
the other Pending Transactions, Jacor will acquire 12 radio stations for a
purchase price aggregating approximately $66.2 million. In addition, Jacor has
entered into seven non-binding letters of intent pursuant to which Jacor and the
prospective sellers have agreed to negotiate exclusively the terms and
conditions of definitive acquisition agreements. If such negotiations and
transactions are successfully completed, the Company would acquire an additional
nine radio stations for an aggregate purchase price of approximately $24.4
million. Jacor is currently negotiating additional possible acquisitions.
However, there can be no assurance that Jacor will successfully complete all or
any such transactions or what the consequences thereof would be. For more
information about Jacor's recent acquisitions and dispositions, see
"Transactions" and "Broadcasting Related Acquisitions."
 
    During 1997, Jacor increased its senior credit facility from up to $600.0
million of availability, consisting of a revolving credit facility of up to
$200.0 million and term loans of up to $400.0 million, to up to $1.15 billion of
availability, consisting of a revolving credit facility of up to $750.0 million
and a term loan of up to $400.0 million. The average interest rate on the senior
credit facility through December 31, 1997 was approximately 6.5% compared to an
average interest rate of approximately 7.4% on Jacor's senior credit facility in
effect on January 1, 1997. As of September 30, 1997, on a pro forma basis the
Company would have had approximately $436.5 million of availability under its
revolving credit facility.

                                      option) of LYONs due February   , 2018. There will be
                                      no periodic interest payments on the LYONs. Each LYON
                                      will have an Issue Price of $     and a principal
                                      amount due at maturity of $1,000.

                                      equivalent basis) calculated from February   , 1998.
 
Conversion Rights...................  Each LYON will be convertible, at the option of the
                                      Holder, at any time on or prior to maturity, unless
                                      previously redeemed or otherwise purchased by Jacor,
                                      into Common Stock at a Conversion Rate of      shares
                                      per LYON. The Conversion Rate will not be adjusted
                                      for accrued Original Issue Discount, but will be
                                      subject to adjustment upon the occurrence of certain
                                      events affecting the Common Stock. Upon conversion,
                                      the Holder will not receive any cash payment
                                      representing accrued Original Issue Discount; such
                                      accrued Original Issue Discount will be deemed paid
                                      by the Common Stock received by the Holder on
                                      conversion. Jacor does not undertake to advise
                                      Holders of the amount of accrued Original Issue
                                      Discount foregone upon conversion. No fractional
                                      interests in shares of Common Stock will be delivered
                                      upon conversion. A Holder otherwise entitled to a
                                      fractional share of Common Stock will receive cash
                                      equal to the then current market value of such
                                      fractional share based on the closing Sale Price (as
                                      defined herein) on the Trading Day (as defined
                                      herein) immediately preceding the Conversion Date.
                                      See "Description of LYONs--Conversion Rights."
 
Ranking.............................  The LYONs will be senior unsecured general
                                      obligations of Jacor ranking senior to any future
                                      unsecured and unsubordinated indebtedness. Because
                                      Jacor is a holding company, the LYONs are effectively
                                      subordinated to any existing and future liabilities,
                                      including trade payables, of Jacor's subsidiaries,
                                      except to the extent Jacor is a creditor of the
                                      subsidiaries recognized as such. As of September 30,
                                      1997, Jacor had $414.5 million of senior secured
                                      indebtedness outstanding which is effectively senior
                                      in right of payment to the LYONs. On a pro forma
                                      basis as of September 30, 1997, after giving effect
                                      to the Nationwide Acquisition, the other Pending
                                      Transactions and any other transaction consummated
                                      after September 30, 1997, long-term debt (excluding
                                      intercompany obligations) of Jacor's subsidiaries, to
                                      which the LYONs would have been effectively
                                      subordinated, totaled approximately $1.2 billion, and
                                      accounts payable, accrued expenses and other current

                                      purposes equal to the excess of the principal amount
                                      at maturity of the LYON over the amount of the Issue
                                      Price. Prospective purchasers of LYONs should be
                                      aware that, although there will be no periodic
                                      payments of interest on the LYONs, accrued Original
                                      Issue Discount will be includable periodically in a

                                      maturity. See "Certain United States Federal Income

                                      February   , 2003. Thereafter, the LYONs are
                                      redeemable for cash at any time at the option of
                                      Jacor, in whole or in part, at Redemption Prices
                                      equal to the Issue Price plus accrued Original Issue
                                      Discount through the date of redemption. See

                                      February   , 2013 for a Purchase Price per LYON of

                                      to pay the Purchase Price on any such Purchase Date
                                      in cash or Common Stock, or any combination thereof.

                                      of the Common Stock to be received from the date such
                                      Market Price is determined to such Purchase Date. In

                                      of a Change in Control of Jacor occurring on or prior
                                      to February   , 2003, Jacor will purchase for cash
                                      any LYON, at the option of the Holder, at a Change in
                                      Control Purchase Price equal to the Issue Price plus
                                      accrued Original Issue Discount through the Change in
                                      Control Purchase Date. The Change in Control purchase
                                      feature of the LYONs may, in certain circumstances,
                                      have an anti-takeover effect. If a Change in Control
                                      were to occur, there can be no assurance that Jacor
                                      would have sufficient funds to pay the Change in
                                      Control Purchase Price required by Holders seeking to
                                      exercise the purchase right because Jacor might also

               SUMMARY UNAUDITED PRO FORMA FINANCIAL INFORMATION
                             (DOLLARS IN THOUSANDS)
 
    The following sets forth summary unaudited pro forma financial information
derived from the Unaudited Pro Forma Financial Information included elsewhere in
this Prospectus Supplement. The unaudited pro forma condensed consolidated
statements of operations for the year ended December 31, 1996 and the LTM ended
September 30, 1997, give effect to each of the following transactions and
related financings as if such transactions and financings had been completed
January 1, 1996: (i) the Nationwide Acquisition, (ii) the transactions described
under "Transactions--Pending Radio Station Transactions" and "--Recent Radio
Station Acquisitions and Dispositions" and "Broadcasting Related Acquisitions"
and (iii) other transactions entered into in 1996 and completed in 1996 or 1997.
The pro forma condensed consolidated balance sheet as of September 30, 1997 has
been prepared as if each of the following transactions and related financings
had occurred on September 30, 1997: (i) the Nationwide Acquisition, (ii) the
other Pending Transactions and (iii) any other transaction consummated after
September 30, 1997.
 
    The Summary Unaudited Pro Forma Financial Information does not purport to
present the actual financial position or results of operations of Jacor had the
transactions and events assumed therein in fact occurred on the dates specified,
nor are they necessarily indicative of the results of operations that may be
achieved in the future. The Summary Unaudited Pro Forma Financial Information is
based on certain assumptions and adjustments described in the notes to the
Unaudited Pro Forma Financial Information and should be read in conjunction
therewith. See "Consolidated Financial Statements" and the notes thereto for
Jacor and Nationwide, incorporated by reference in this Prospectus Supplement.

(1) "Broadcast cash flow" means operating income before depreciation and
    amortization, and corporate general and administrative expenses. "EBITDA"
    means operating income before depreciation and amortization. Broadcast cash
    flow and EBITDA should not be considered in isolation from, or as a
    substitute for, operating income, net income or cash flow and other
    consolidated income or cash flow statement data computed in accordance with
    generally accepted accounting principles or as a measure of a company's
    profitability or liquidity. Although these measures of performance are not
    calculated in accordance with generally accepted accounting principles, they
    are widely used in the broadcasting industry as a measure of a company's
    operating performance because they assist in comparing station performance
    on a consistent basis across companies without regard to depreciation and
    amortization, which can vary significantly depending on accounting methods
    (particularly where acquisitions are involved) or non-operating factors such
    as historical cost bases. Broadcast cash flow also excludes the effect of
    corporate general and administrative expenses, which generally do not relate
    directly to station performance. Pro forma EBITDA excludes $2,303 of special
    bonuses.
 
(2) Broadcast cash flow margin equals broadcast cash flow as a percentage of net
    revenue.

                                  TRANSACTIONS
 
NATIONWIDE ACQUISITION
 
    In December 1997, Jacor entered into an Agreement of Sale ("Sale Agreement")
with Nationwide to purchase the assets of 17 radio stations for a purchase price
of approximately $620.0 million in cash (the "Nationwide Acquisition"). These
stations are KDMX-FM and KEGL-FM in Dallas, Texas (KEGL-FM to be acquired upon
consummation of a pending exchange entered into by Nationwide); KHMX-FM and
KTBZ-FM in Houston, Texas; KMJZ-FM and KSGS-AM in Minneapolis, Minnesota;
KGLQ-FM and KZZP-FM in Phoenix, Arizona; WPOC-FM in Baltimore, Maryland;
WGAR-FM, WMJI-FM and WMMS-FM in Cleveland, Ohio; WCOL-FM, WFII-AM and WNCI-FM in
Columbus, Ohio; and KXGL-FM and KMCG-FM in San Diego, California (collectively,
the "Nationwide Stations"). Of the purchase price, $30.0 million has been placed
in escrow pending the closing of the Nationwide Acquisition.
 
    Jacor anticipates that the sources of the cash to be used to satisfy the
purchase price will be obtained from a combination of borrowing under its Credit
Facility and the net proceeds from this Offering and the Related Offerings.
 
    The closing of the Nationwide Acquisition is subject to certain conditions,
including expiration of the applicable waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
("Hart-Scott-Rodino") and the consent of the FCC to the assignment of the FCC
licenses of the Nationwide Stations to Jacor. Because the Nationwide Acquisition
would result in the Company owning 10 stations in San Diego, in which the
maximum number of stations allowed to be owned pursuant to FCC rules is eight,
Jacor will divest two of the Company's radio stations in San Diego. Jacor has
not yet determined which two stations it will divest. In addition, Jacor has had
discussions with the Antitrust Division of the Department of Justice regarding
the effect of the Nationwide Acquisition in Columbus, Cleveland and San Diego
and has received an investigative demand from the Ohio Attorney General
regarding the effect of the Nationwide Acquisition in Columbus and Cleveland. No
determinations have been made as to whether the Antitrust Division or the Ohio
Attorney General will raise any objections to the Nationwide Acquisition that
would require changes in the terms of the Nationwide Acquistion. See "Risk
Factors--Risks of Acquisition Strategy," "--Increased Antitrust Scrutiny" and
"--FCC Regulation of Broadcasting Industry" of the accompanying Prospectus. The
Hart-Scott-Rodino and the FCC applications for the Nationwide Acquisition were
filed in January 1998 and November 1997, respectively.
 
    The Sale Agreement also provides that, after April 1, 1998, at the option of
Jacor, the closing of the Nationwide Acquisition may occur before the FCC
consent has become a final order. In addition to options to terminate for
various matters including a breach of the Sale Agreement, if the parties to the
Sale Agreement shall have materially satisfied all of their respective
obligations under the Sale Agreement and, nevertheless, the closing of the
Nationwide Acquisition has not taken place prior to December 31, 1998, either
party may terminate the Sale Agreement. Jacor anticipates that the closing will
occur during the second quarter of 1998.
 
PENDING RADIO STATION TRANSACTIONS
 
    All of the following pending radio station transactions are subject to
various conditions, including approval by the FCC. There can be no assurance
that Jacor will be successful in consummating all such transactions in a timely
manner or on the terms described herein. See "Risk Factors--Increased Antitrust

year to date average interest rate on the existing Credit Facility was

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
    The following unaudited pro forma financial information, which is based on
the historical financial statements of Jacor and Nationwide, has been prepared
to illustrate the effects of the acquisitions and related financings described
below.
 
    The unaudited pro forma condensed consolidated statements of operations for
the nine months ended September 30, 1997, the nine months ended September 30,
1996, the LTM ended September 30, 1997 and the year ended December 31, 1996 give
effect to each of the following transactions as if such transactions had been
completed January 1, 1996: (i) the Nationwide Acquisition, (ii) the acquisitions
described under "Transactions--Pending Radio Station Transactions" and "--Recent
Radio Station Acquisitions and Dispositions" and "Broadcasting Related
Acquisitions" and (iii) other transactions entered into in 1996 and completed in
1996 or 1997. The pro forma condensed consolidated balance sheet as of September
30, 1997 has been prepared as if each of the following transactions and related
financings had occurred on September 30, 1997: (i) the Nationwide Acquisition,
(ii) other Pending Transactions and (iii) any other transaction consummated
after September 30, 1997.
 
    The Pending Transactions will be accounted for using the purchase method of
accounting. The total purchase costs of the Pending Transactions will be
allocated to the tangible and intangible assets and liabilities acquired based
upon their respective fair values. The allocation of the aggregate purchase
price reflected in the Unaudited Pro Forma Financial Information is preliminary.
The final allocation of the purchase price will be contingent upon the receipt
of final appraisals of the acquired assets. The Unaudited Pro Forma Financial

or the results that might have occurred if the foregoing transactions had been
consummated on the indicated dates.
 
    The Unaudited Pro Forma Financial Information should be read in conjunction

    divestitures of two San Diego stations (see Note (r)) and projected expense
    savings of $10,476 and $13,707 for the nine months ended September 30, 1997
    and the year ended December 31, 1996, respectively. Expense savings will
    result from the elimination of redundant broadcast operating expenses
    arising from the operation of multiple stations in certain broadcast areas,
    changes in benefit plan and compensation structures to conform with Jacor's
    and the elimination of Nationwide's corporate office function. Estimated
    savings are as follows:

GENERAL
 
    Jacor, upon consummation of the Pending Transactions, will be the second
largest radio group in the United States in terms of number of stations and will
be the fourth largest radio group in the nation as measured by revenue and is
the country's third largest provider of syndicated radio programming. The
Company will own and/or operate 186 radio stations and one television station in
48 broadcast areas across the United States upon consummation of the Pending
Transactions. The Company's broadcast areas, as a group, are among the most
attractive in the country, demonstrating radio revenue growth in excess of the
radio industry average over the last five years. Jacor also produces more than
50 syndicated programs and services for more than 4,000 radio stations, which
programs include RUSH LIMBAUGH, THE DR. LAURA SCHLESSINGER SHOW and DR. DEAN
EDELL, the top three rated radio programs in the United States. In 1996, the
Company would have been number one or number two in terms of radio revenue rank
in 25 of its 35 ranked broadcast areas. On a pro forma basis, the Company would
have had net revenue and broadcast cash flow of $682.2 million and $224.2
million, respectively, for the LTM ended September 30, 1997.
 
    Jacor's principal executive offices are located at 50 East RiverCenter
Boulevard, 12th Floor, Covington, Kentucky 41011 and its telephone number is
(606) 655-2267.
 
BUSINESS STRATEGY
 
    Jacor's strategic objective is to maximize revenue and broadcast cash flow
by becoming the leading radio broadcaster in geographically diverse broadcast
areas and by leveraging its expertise in programming production, syndication and
distribution. Jacor intends to acquire individual radio stations, radio groups
and/or businesses that provide radio broadcasting services that strengthen its
strategic position in the radio industry and enhance its operating performance.
Specifically, Jacor's business strategy centers upon:
 
    BROADCAST AREA REVENUE LEADERSHIP.  Jacor strives to maximize its audience
ratings in each of its broadcast areas in order to capture the largest share of
the radio advertising revenue in each such area and to attract advertising away
from other media. Jacor believes that the most effective way to capture a higher
percentage of advertising revenue is to operate multiple radio stations within a
broadcast area, tailoring each station's programming to deliver highly effective
access to a target demographic. In implementing its multi-station strategy,
Jacor utilizes its programming expertise over a broad range of radio formats to
create distinct station personalities within a broadcast area. Jacor further
enhances its ability to increase its revenues through a more complete coverage
of the listener base by being an industry leader in successfully operating AM
stations.
 
    DEVELOPMENT OF "STICK" PROPERTIES.  In addition to acquiring developed, cash
flow producing stations, Jacor also strategically acquires underdeveloped
"stick" properties (I.E., properties with insignificant ratings and/or little or
no positive broadcast cash flow). Jacor believes that acquisitions of
strategically located "stick" properties often provide greater potential for
revenue and broadcast cash flow growth than do acquisitions of developed
properties. Historically, Jacor has been able to improve the ratings, revenue
and broadcast cash flow of its "stick" properties with increased marketing and
focused programming that complements its existing radio station formats and by
leveraging the management expertise and operational support of regional
clusters. Additionally, Jacor increases the revenue and broadcast cash flow of
"stick" properties by encouraging advertisers to buy advertising in a package
with its more established stations. Jacor believes that the Company's portfolio
of 99 "stick" properties creates significant potential for revenue and broadcast
cash flow growth. For example, Jacor improved the broadcast cash flow of the 47
"stick" properties it owned or operated as of May 1, 1997 from approximately
$3.4 million in 1996 to approximately $9.7 million in 1997, an increase of
approximately 185%.
 
    DEVELOPMENT OF REGIONAL CLUSTERS AROUND CORE BROADCAST AREAS.  Jacor
believes it can leverage its position as the leader in a core broadcast area to
create additional revenue and broadcast cash flow
 
                                      S-29
<PAGE>
opportunities by building regional multi-station clusters around Jacor's core
broadcast areas. Utilizing programming from its core broadcast areas, Jacor
provides its regional clusters with high quality programming which would not
otherwise be economically viable in such smaller broadcast areas, thereby
spreading the costs associated with the delivery of such programming across a
greater number of stations. By improving the ratings of its regional stations
with such enhanced programming, Jacor believes it can generate incremental
revenue and broadcast cash flow. For example, Jacor has utilized this strategy
in the Denver, Colorado broadcast area by acquiring stations in Casper and
Cheyenne, Wyoming and Fort Collins/Greeley, Colorado to develop a regional
cluster.
 
    STRATEGIC ACQUISITIONS OF COMPLEMENTARY STATIONS.  Jacor focuses its
acquisition strategy on acquiring stations with powerful broadcast signals that
complement its existing portfolio and strengthen its overall competitive
position. By operating multiple stations within its broadcast areas, Jacor seeks
to position itself as the most efficient advertising medium in a geographic
location, providing advertisers with wide access to a variety of demographic
groups through a single purchase of advertising time. Through the acquisition of
additional stations within an existing broadcast area, Jacor spreads its fixed
costs over a larger base of stations and creates operating efficiencies enabling
it to generate higher broadcast cash flow. Jacor may enter additional broadcast
areas, domestic or international, through acquisitions of radio groups that have
multiple station platforms and/or through acquisitions of individual stations in
new locations where Jacor believes a revenue-leading position can be created.
 
    Since the enactment of the Telecommunications Act of 1996 on February 8,
1996, through December 31, 1997, Jacor has acquired or entered into binding
agreements to acquire 158 radio stations and two television stations, and
entered into an exclusive sales agency agreement to provide programming to and
sell air time for two radio stations located in Baja California, Mexico. The
aggregate consideration paid and to be paid for these transactions is
approximately $2.3 billion. In addition, Jacor has exchanged one of the
television stations and seven radio stations for 17 radio stations in
transactions valued in the aggregate at approximately $315.0 million.
 
    ACQUISITIONS OF BROADCAST RELATED BUSINESSES.  Jacor strengthens its
strategic position in the radio industry through the acquisition and operation
of businesses that provide services to radio broadcasting companies. In 1997,
Jacor significantly expanded its base of syndicated radio programming available
to both Jacor's radio stations and other broadcasting companies. Jacor acquired
for approximately $340.3 million, a leading producer and distributor of radio
programming research, two leading providers of syndicated talk radio
programming, a leading provider of satellite and network services for the radio
broadcasting industry and a leading provider of traffic reporting services in
the San Diego and Los Angeles, California broadcast areas.
 
    In addition to generating cash flow, these broadcast related services
enhance the Company's ability to (i) increase ratings for its existing stations
(ii) transform "stick" properties into broadcast cash flow producing properties
and (iii) maintain long-term relationships with Jacor's on-air talent. For
example, Jacor increased the audience ratings of KEWS-AM in Portland, Oregon by
approximately 64% after adding the RUSH LIMBAUGH show to that station's program
line-up. By combining the national reach of the Company's radio stations with
the network sales forces acquired by Jacor, the Company seeks to maximize the
value of commercial broadcast inventory that it can then resell to national
advertisers. See "Broadcasting Related Acquisitions." The Company also will
benefit from the NSN Network Services distribution network acquired by Jacor in
1997, which network will create efficiencies and lower costs related to the
distribution of programming among the Company's radio stations.

BROADCASTING RELATED BUSINESSES AND SERVICES
 
    Jacor currently owns, produces and distributes syndicated programming for
radio broadcasting, including such programs as RUSH LIMBAUGH, THE DR. LAURA
SCHLESSINGER SHOW and DR. DEAN EDELL. The RUSH LIMBAUGH show is a nationally
syndicated talk radio program broadcast on more than 600 radio stations. THE DR.
LAURA SCHLESSINGER SHOW is a nationally syndicated talk radio program broadcast
on more than 400 radio stations. The DR. DEAN EDELL show is a health care and
medicine talk radio program broadcast on more than 300 radio stations. These
three programs are the three highest rated syndicated talk radio programs in the
United States. Jacor is also the producer and distributor of other syndicated
programs and services, including LEEZA GIBBONS ENTERTAINMENT TONIGHT ON THE
RADIO, THE MICHAEL REAGAN SHOW, AFTER MIDNITE WITH BLAIR GARNER and THE JIM ROME
SHOW. These nationally syndicated programs and services are currently broadcast
on more than 4,000 radio stations pursuant to over 6,300 contracts. See
"Broadcasting Related Acquisitions."
 
    Jacor's broadcasting related services include comprehensive radio research
services and a national, in-house sales force. Premiere's mediabase research
service provides music play-list and on-air promotion tracking and call-out
research for seven radio formats, which research services help radio station
affiliates increase their audience share and ratings. Jacor provides the
research services in exchange for commercial broadcast inventory instead of on a
cash basis in order to make the services more attractive to radio stations which
have limited cash resources and/or excess commercial broadcast inventory.
 
    Premiere's national, in-house network radio sales force and infrastructure
sells commercial broadcast inventory to more than 350 national advertisers.
Jacor leverages its sales force and generates additional revenues without
significant additional overhead costs by providing network advertising sales
representation services, on a commission basis, to third-party radio networks
and independent syndicated programming and service suppliers that do not have
their own sales forces. Jacor believes that Premiere is presently the second
largest network radio advertising sales representative in the United States in
terms of its gross billings. It presently represents nine independent radio
networks, including WOR Radio Networks, One-on-One Sports Radio Network and
Accuweather. Also, upon Jacor's acquisition of MultiVerse, Premiere became the
network radio sales representative for shows such as COUNTRY HEARTLINES WITH
JOHN CRENSHAW and BEYOND THE BELTWAY WITH BRUCE DUMONT.
 
    In addition, Jacor will benefit from the distribution network acquired with
NSN Network Services, which network will create efficiencies and lower costs
related to the distribution of programming among the Company's radio stations.
Further, this network will continue to enhance the Company's back-office
backbone by facilitating the sharing of financial data and other communications.
 
TELEVISION
 
    Jacor owns a television station in the Cincinnati broadcast area where it
currently owns and operates multiple radio stations. By operating a television
station in the broadcast area where Jacor has a significant radio presence,
Jacor has realized significant operating efficiencies including shared news
departments and reduction of administrative overhead. Jacor currently operates
this television station under a temporary waiver of an FCC rule that restricts
ownership of television and radio stations in the same market. This waiver will
continue until at least six months after the FCC completes a pending rulemaking
proceeding in which it is considering whether to substantially liberalize this
rule.
 
    The following table sets forth certain information regarding the Cincinnati
television station and the broadcast area in which it operates:

                              DESCRIPTION OF LYONS
 
    The LYONs are to be issued under an indenture to be dated as of February   ,
1998 (the "Indenture"), between Jacor and The Bank of New York, as trustee (the
"Trustee"), a copy of which is filed as an exhibit to the Registration Statement
of which the Prospectus is a part. The terms of the Indenture are also governed
by certain provisions contained in the Trust Indenture Act of 1939, as amended
(the "Trust Indenture Act"). The following summaries of certain provisions of
the LYONs and the Indenture do not purport to be complete and are subject to,
and are qualified in their entirety by reference to, all of the provisions of
the LYONs and the Indenture, including the definitions therein of certain terms
which are not otherwise defined in this Prospectus and those terms made a part
of the Indenture by reference to the Trust Indenture Act as in effect on the
date of the Indenture. Wherever particular provisions or defined terms of the
Indenture (or of the Form of LYON which is a part thereof) are referred to, such
provisions or defined terms are incorporated herein by reference. References
herein are to sections in the Indenture and paragraphs in the Form of LYON.
 
GENERAL
 
    The LYONs will be senior unsecured general obligations of Jacor limited to
$            aggregate principal amount at maturity ($            aggregate
principal amount at maturity if the Underwriter's over-allotment option is
exercised in full) and will mature on February   , 2018. The principal amount at
maturity of each LYON is $1,000 and will be payable at the office of the Paying
Agent, initially the Trustee, or an office or agency maintained by Jacor for
such purpose in the Borough of Manhattan, The City of New York. (Sections 2.03,
2.04 and 4.05 and Form of LYON, paragraph 3.)
 
    The LYONs are being offered at a substantial discount from their principal
amount at maturity. See "Certain United States Federal Income Tax
Considerations--Original Issue Discount." There will be no periodic payments of
interest. The calculation of the accrual of Original Issue Discount (the
difference between the Issue Price and the principal amount at maturity of a
LYON) in the period during which a LYON remains outstanding will be on a
semi-annual bond equivalent basis using a 360-day year composed of twelve 30-day
months; such accrual will commence on the issue date of the LYONs. (Form of
LYON, paragraph 1.) In the event of the maturity, conversion, purchase by the
Company at the option of a Holder, or redemption of a LYON, Original Issue
Discount and interest, if any, will cease to accrue on such LYON, under the
terms and subject to the conditions (summaries of which are set forth below) of
the Indenture. (Section 3.08.) Jacor may not reissue a LYON that has matured or
been converted, purchased by Jacor at the option of a Holder, redeemed or
otherwise cancelled (except for registration of transfer, exchange or
replacement thereof). (Section 2.10.)
 
    To the extent that the operations of Jacor are conducted through, and the
assets of Jacor are owned by, wholly owned subsidiaries, Jacor's cash flow and
consequent ability to meet its debt obligations are dependent in part upon the
earnings of its subsidiaries and on dividends and other payments therefrom.
Since the LYONs are solely an obligation of Jacor, Jacor's subsidiaries are not
obligated or required to pay any amounts due pursuant to the LYONs or to make
funds available therefor in the form of dividends or advances to Jacor.
 
    The LYONs will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount at maturity or an integral multiple
thereof. (Form of LYON, paragraph 10.) Jacor will maintain in the Borough of
Manhattan, The City of New York, an office or agency of the Trustee, Registrar,
Paying Agent and Conversion Agent where LYONs may be presented or surrendered
for payment, where LYONs may be surrendered for registration of transfer,
exchange, purchase, redemption or conversion and where notices and demands to or
upon Jacor in respect of the LYONs and the Indenture may be served, which shall
initially be the corporate trust office of the Trustee in such Borough. (Section
4.05.) Jacor will not charge a service charge for any registration of transfer
or exchange of LYONs;
 
                                      S-38
<PAGE>
however, Jacor may require payment by a Holder of a sum sufficient to cover any
tax, assessment or other governmental charge payable in connection therewith.
(Section 2.06.)
 
RANKING OF LYONS; EFFECT OF CORPORATE STRUCTURE
 
    The LYONs will be senior unsecured general obligations of Jacor, ranking
equally with other senior unsecured obligations of Jacor. The Indenture does not
contain any provisions that limit the ability of Jacor or any of its
subsidiaries to incur indebtedness or to grant security interests or liens in
respect of their assets or that afford Holders protection in the event of a
highly leveraged or similar transaction involving Jacor.
 
    Jacor is a holding company. Accordingly, the LYONs will be effectively
subordinated to all existing and future liabilities, including trade payables,
of Jacor's subsidiaries, except to the extent Jacor is a creditor of the
subsidiaries recognized as such. Any right of Jacor as an equity holder to
participate in any distribution of the assets of any of Jacor's subsidiaries
upon the liquidation, reorganization or insolvency of such subsidiaries (and the
consequent right of Holders to participate in such distribution) will be subject
to the claims of the creditors (including trade creditors) and any preferred
shareholders of such subsidiary. As of September 30, 1997, Jacor had $414.5
million of senior secured indebtedness outstanding which is effectively senior
in right of payment to the LYONs. On a pro forma basis as of September 30, 1997,
after giving effect to the Nationwide Acquisition, the other Pending
Transactions and any other transaction consummated after September 30, 1997,
long-term debt (excluding intercompany obligations) of Jacor's subsidiaries, to
which the LYONs would have been effectively subordinated, totaled approximately
$1.2 billion, and accounts payable, accrued expenses and other current
liabilities totaled approximately $86.5 million. Jacor and its subsidiaries
expect to incur additional indebtedness from time to time. The LYONs offered
hereby will rank PARI PASSU with the LYONs due 2011. See "Description of
Indebtedness-- Liquid Yield Option Notes due 2011" in the accompanying
Prospectus.
 
    The LYONs are obligations exclusively of Jacor. Substantially all of Jacor's
business activities and assets are operated or held by its subsidiaries. As a
holding company, Jacor's ability to meet its financial obligations, including
its obligations under the LYONs, is dependent primarily upon the receipt of
interest and principal payments on intercompany advances, management fees, cash
dividends and other payments from its subsidiaries. The subsidiaries are
distinct legal entities and have no obligation, contingent or otherwise, to pay
any amounts due pursuant to the LYONs or to make any funds available therefor,
whether by dividends, interest, loans, advances or other payments. In addition,
the payment of dividends and the making of loans, advances and other payments to
Jacor by its subsidiaries (i) are subject to restrictions contained in the
Credit Facility, JCC's senior subordinated indebtedness, statutes or other
contractual agreements, (ii) are contingent upon the earnings of those
subsidiaries and (iii) are subject to various business and other considerations.
 
CONVERSION RIGHTS
 
    A Holder of a LYON may convert it into Common Stock at any time before the
close of business on February   , 2018, provided, however, that if a LYON is
called for redemption, the Holder may convert it at any time before the close of
business on the Redemption Date. A LYON in respect of which a Holder has
delivered a written purchase notice (a "Purchase Notice") or a Change in Control
Purchase Notice exercising the option of such Holder to require Jacor to
purchase such LYON may be converted only if such notice is withdrawn in
accordance with the terms of the Indenture. (Sections 3.08, 3.09 and 3.10 and
Form of LYON, paragraph 8.)
 
    The initial Conversion Rate for the LYONs is      shares of Common Stock per
LYON, subject to adjustment upon the occurrence of certain events described
below. (Form of LYON, paragraph 8.) See "Price Range of Common Stock." A Holder
otherwise entitled to a fractional share of Common Stock will receive cash equal
to the then current market value of such fractional share based on the closing
Sale Price
 
                                      S-39
<PAGE>
on the Trading Day immediately preceding the Conversion Date. (Section 10.03 and
Form of LYON, paragraph 8.) A Holder may convert a portion of such Holder's
LYONs so long as such portion is $1,000 principal amount at maturity or an
integral multiple thereof. (Section 10.01 and Form of LYON, paragraph 8.)
 
    To convert a LYON into Common Stock, a Holder must (i) complete and manually
sign the conversion notice on the back of the LYON (or complete and manually
sign a facsimile thereof) and deliver such notice to the Conversion Agent
(initially the Trustee) at the office maintained by the Conversion Agent for
such purpose, (ii) surrender the LYON to the Conversion Agent, (iii) if
required, furnish appropriate endorsements and transfer documents and (iv) if
required, pay all transfer or similar taxes. Pursuant to the Indenture, the date
on which all of the foregoing requirements have been satisfied is the Conversion
Date. (Sections 10.02 and 10.04 and Form of LYON, paragraph 8.)
 
    Upon conversion of a LYON, a Holder will not receive any cash payment
representing accrued Original Issue Discount. Jacor's delivery to the Holder of
the fixed number of shares of Common Stock into which the LYON is convertible
(together with the cash payment, if any, in lieu of a fractional share of Common
Stock) will be deemed to satisfy Jacor's obligation to pay the principal amount
of the LYON, including the accrued Original Issue Discount attributable to the
period from the Issue Date through the Conversion Date. Thus, the accrued
Original Issue Discount will be deemed to be paid in full rather than cancelled,
extinguished or forfeited. The Conversion Rate will not be adjusted at any time
during the term of the LYONs for such accrued Original Issue Discount. Jacor
does not undertake to advise Holders of the amount of accrued Original Issue
Discount foregone upon conversion. A certificate for the number of full shares
of Common Stock into which any LYON is converted (and for cash in lieu of a
fractional share of Common Stock) will be delivered through the Conversion Agent
as soon as practicable following the Conversion Date. (Sections 2.08 and 10.02.)
For a discussion of the tax treatment of a Holder receiving Common Stock upon
conversion, see "Certain United States Federal Income Tax Consequences--
Conversion."
 
    The Conversion Rate will be adjusted for dividends or distributions on
Common Stock payable in Common Stock or other capital stock of Jacor;
subdivisions, combinations or certain reclassifications of Common Stock;
distributions to all holders of Common Stock of certain rights, warrants or
options to purchase Common Stock or securities convertible into Common Stock for
a period expiring within 60 days after the record date for such distribution at
a price per share less than the Sale Price at the time of determination; and
distributions to all holders of Common Stock of assets or debt securities of
Jacor or rights, warrants or options to purchase securities of Jacor (excluding
cash dividends or other cash distributions from consolidated current net income
or retained earnings other than any Extraordinary Cash Dividend). However, no
adjustment need be made (i) if Holders may participate in the transactions on a
basis and with notice that the Board of Directors of Jacor determines to be fair
and appropriate, (ii) for rights to purchase Common Stock pursuant to a Jacor
dividend or interest reinvestment plan, (iii) for changes in the par value of
the Common Stock or (iv) unless such adjustment, together with any other
adjustments similarly deferred, equals at least 1% of the then current
Conversion Rate. In cases where the fair market value of the portion of assets,
debt securities or rights, warrants or options to purchase securities of Jacor
applicable to one share of Common Stock distributed to stockholders exceeds the
Average Sale Price per share of Common Stock, or such Average Sale Price exceeds
such fair market value of such portion of assets, debt securities or rights,
warrants or options so distributed by less than $1.00, rather than being
entitled to an adjustment in the Conversion Rate, the Holder of a LYON upon
conversion thereof will be entitled to receive, in addition to the shares of
Common Stock into which such LYON is convertible, the kind and amounts of
assets, debt securities or rights, options or warrants comprising the
distribution that such Holder would have received if such Holder had converted
such LYON immediately prior to the record date for determining the shareholders
entitled to receive the distribution. The Indenture permits Jacor to increase
the Conversion Rate from time to time at its discretion. (Sections 10.06, 10.07,
10.08, 10.10, 10.12 and 10.14 and Form of LYON, paragraph 8.)
 
                                      S-40

    "AVERAGE SALE PRICE" means the average of the Sale Prices of the Common
Stock for the shorter of (i) 30 consecutive Trading Days ending on the last full
Trading Day prior to the Time of Determination with respect to the rights,
options, warrants or distribution in respect of which the Average Sale price is
being calculated, or (ii) the period (x) commencing on the date next succeeding
the first public announcement of (a) the issuance of rights, options or warrants
or (b) the distribution, in each case, in respect of which the Average Sale
Price is being calculated and (y) proceeding through the last full trading day
prior to the Time of Determination with respect to the rights, warrants or
distribution in respect of which the Average Sale Price is being calculated, or
(iii) the period,if any, (x) commencing on the date next succeeding the Ex-
Dividend Time with respect to the next preceding (a) issuance of rights,
warrants, or options or (b) distribution, in each case, for which an adjustment
is required by the Indenture and (y) proceeding through the last full Trading
Day prior to the Time of Determination with respect to the rights, warrants, or
options or distribution in respect to which the Average Sale Price is being
calculated.
 
    If the Ex-Dividend Time (or in the case of a subdivision, combination or
reclassification, the effective date with respect thereto) with respect to a
dividend, subdivision, combination or reclassification to which certain sections
of the Indenture apply occurs during the period applicable for calculating
"Average Sale Price" pursuant to the definition in the preceding sentence,
"Average Sale Price" shall be calculated for such period in a manner determined
by the Board of Directors to reflect the impact of such dividend, subdivision,
combination or reclassification on the Sale Price of the Common Stock during
such period.
 
    "TIME OF DETERMINATION" means the time and date of the earlier of (i) the
determination of stockholders entitled to receive rights, warrants, or options
or a distribution, in each case, to which certain sections of the Indenture
apply and (ii) the time "EX-DIVIDEND" trading for such rights, options, warrants
or distribution on the Nasdaq National Market or such other national or regional
exchange or market on which the Common Stock is then listed or quoted.
 
    If Jacor is party to a consolidation, merger or binding share exchange or a
transfer of all or substantially all of its assets which is otherwise permitted
under the terms of the Indenture, the right to convert a LYON into Common Stock
may be changed into a right to convert it into the kind and amount of
securities, cash or other assets of Jacor which the Holder would have received
if the Holder had converted such Holder's LYONs immediately prior to the
transaction. (Section 10.14.)
 
    In the event of a taxable distribution to holders of Common Stock which
results in an adjustment of the Conversion Rate (or in which Holders otherwise
participate) or in the event the Conversion Rate is increased at the discretion
of Jacor, the Holders of the LYONs may, in certain circumstances, be deemed to
have received a distribution subject to United States Federal income tax as a
dividend. See "Certain United States Federal Income Tax
Consequences--Constructive Dividend."
 
REDEMPTION OF LYONS AT THE OPTION OF JACOR
 
    No sinking fund is provided for the LYONs. Prior to February   , 2003, the
LYONs will not be redeemable at the option of Jacor. Thereafter, Jacor may
redeem the LYONs for cash as a whole at any time, or from time to time in part,
upon not less than 30 days' nor more than 60 days' notice of redemption given by
mail to Holders of LYONs. Any such redemption must be in multiples of $1,000
principal amount at maturity. (Sections 3.01, 3.02 and 3.03 and Form of LYON,
paragraphs 5 and 7.)

    The table below shows Redemption Prices of a LYON per $1,000 principal
amount at maturity on February   , 2003, at each February   thereafter prior to
maturity, and at maturity on February   , 2018, which prices reflect the accrued
Original Issue Discount calculated through each such date. The Redemption Price
of a LYON redeemed between such dates would include an additional amount
reflecting the additional Original Issue Discount accrued from the next
preceding date in the table through the actual Redemption Date. (Form of LYON,
paragraph 5.)

    If fewer than all of the LYONs are to be redeemed, the Trustee shall select
the LYONs to be redeemed in principal amounts at maturity of $1,000 or integral
multiples thereof by lot, pro rata or by another method the Trustee considers
fair and appropriate. If a portion of a Holder's LYONs is selected for partial
redemption and such Holder converts a portion of such LYONs prior to such
redemption, such converted portion shall be deemed to be of the portion selected
for redemption. (Section 3.02.)
 
    In connection with any redemption of the LYONs, Jacor may arrange, in lieu
of redemption, for the purchase and conversion of any LYONs called for
redemption by an agreement with one or more investment bankers or other
purchasers to purchase all or a portion of such LYONs by paying to the Trustee
in trust for the Holders whose LYONs are to be so purchased, on or before the
close of business on the Redemption Date, an amount that, together with any
amounts deposited with the Trustee by Jacor for redemption of such LYONs, is not
less than the Redemption Price, together with interest, if any, accrued to the
Redemption Date, of such LYONs.
 
PURCHASE OF LYONS AT THE OPTION OF THE HOLDER
 
    On February   , 2003, February   , 2008 and February   , 2013 (each, a
"Purchase Date"), Jacor will become obligated to purchase, at the option of the
Holder thereof, any outstanding LYON for which a written Purchase Notice has
been delivered by the Holder to the Paying Agent or an office or agency
maintained by Jacor for such purpose in the Borough of Manhattan, The City of
New York, at any time from the opening of business on the date that is 20
business days preceding such Purchase Date until the close of business on such
Purchase Date and for which such Purchase Notice has not been withdrawn, subject
to certain additional conditions set forth in part in the following paragraphs.
(Section 3.08 and Form of LYON, paragraph 6.)

    The Purchase Price payable in respect of a LYON will be equal to the Issue
Price plus accrued Original Issue Discount through the Purchase Date, with
respect to each Purchase Date. Jacor, at its option, may elect to pay such
Purchase Price in cash or Common Stock, or any combination thereof. (Section
3.08 and Form of LYON, paragraph 6.) For a discussion of the tax treatment of
such a transaction, see "Certain United States Federal Income Tax
Consequences--Other Disposition."
 
    Jacor will be required to give notice (the "Jacor Notice") not less than 20
business days prior to each Purchase Date (the "Jacor Notice Date") to all
Holders at their addresses shown in the register of the Registrar (and to
beneficial owners as required by applicable law) stating, among other things
(specifying the percentages of each), (i) whether Jacor will pay the Purchase
Price of the LYONs in cash or Common Stock, or any combination thereof, (ii) if
Jacor elects to pay in Common Stock, in whole or in part, the method of
calculating the market price of the Common Stock and (iii) the procedures that
Holders must follow to require Jacor to purchase LYONs from such Holders.
(Section 3.08.)
 
    The Purchase Notice given by any Holder requiring Jacor to purchase LYONs
shall state (i) the certificate numbers of the LYONs to be delivered by such
Holder for purchase by Jacor; (ii) the portion of the principal amount at
maturity of LYONs to be purchased, which portion must be $1,000 or an integral
multiple thereof; (iii) that such LYONs are to be purchased by Jacor pursuant to
the applicable provisions of the LYONs and (iv) if Jacor elects, pursuant to the
Jacor Notice, to pay a specified percentage of the Purchase Price in Common
Stock but such specified percentage is ultimately to be paid in cash because any
of the conditions to payment of such specified percentage of the Purchase Price
in Common Stock contained in the Indenture is not satisfied prior to the close
of business on the Purchase Date, as described below, that such Holder elects
(a) to withdraw such Purchase Notice as to some or all of the LYONs to which it
relates (stating the principal amount at maturity and certificate numbers of the
LYONs as to which such withdrawal shall relate) or (b) to receive cash in
respect of the Purchase Price of all LYONs subject to such Purchase Notice. If
the Holder fails to indicate such Holder's choice with respect to the election
described in clause (iv) above in the Purchase Notice, such Holder shall be
deemed to have elected to receive cash for the specified percentage that was to
have been payable in Common Stock. (Section 3.08.) See "Certain United States
Federal Income Tax Consequences--Other Disposition."
 
    Any Purchase Notice may be withdrawn by the Holder by a written notice of
withdrawal delivered to the Paying Agent prior to the close of business on the
Purchase Date. The notice of withdrawal shall state the principal amount at
maturity and the certificate numbers of the LYONs as to which the withdrawal
notice relates and the principal amount at maturity, if any, which remains
subject to the Purchase Notice. (Section 3.10)
 
    If Jacor elects to pay the Purchase Price, in whole or in part, in shares of
Common Stock, the number of shares of Common Stock to be delivered in respect of
the specified percentage of the Purchase Price to be paid in Common Stock shall
be equal to the dollar amount of such specified percentage of the Purchase Price
divided by the Market Price (as defined below) of a share of Common Stock. No
fractional interests in shares of Common Stock will be delivered upon any
purchase by Jacor of LYONs in payment, in whole or in part, of the Purchase
Price. Instead, Jacor will pay cash based on the Market Price for all fractional
shares of Common Stock. (Section 3.08.) Each Holder whose LYONs are purchased at
the option of such Holder as of the Purchase Date shall receive the same
percentage of cash or Common Stock in payment of the Purchase Price for such
LYONs, except as described above with regard to the payment of cash in lieu of
fractional shares of Common Stock. See "Certain United States Federal Income Tax
Considerations-- Other Disposition."
 
                                      S-43
<PAGE>
    The "Market Price" means the average of the Sale Price of the Common Stock
for the five Trading Day (as defined below) period ending on the third Trading
Day prior to the applicable Purchase Date, appropriately adjusted to take into
account the occurrence, during the seven Trading Days preceding such Purchase
Date, of certain events described under "--Conversion Rights" that would result
in an adjustment of the Conversion Rate with respect to the Common Stock.
(Section 3.08.) The "Sale Price" of the Common Stock on any Trading Day means
the closing per share sale price for the Common Stock (or, if no closing sale
price is reported, the average of the bid and ask prices or, if more than one in
either case the average of the average bid and average ask prices) on such
Trading Day as reported in composite transactions for the principal United
States securities exchange on which the Common Stock is traded or, if the Common
Stock is not listed on a United States national or regional securities exchange,
as reported by the National Association of Securities Dealers Automated
Quotation System. A "Trading Day" means each day on which the securities
exchange or quotation system which is used to determine the Sale Price is open
for trading or quotation. (Section 1.01.) Because the Market Price of the Common
Stock is determined prior to a Purchase Date, Holders of LYONs bear the market
risk with respect to the value of the Common Stock to be received from the date
such Market Price is determined to the Purchase Date. Jacor may pay the Purchase
Price, in whole or in part, in Common Stock only if the information necessary to
calculate the Market Price is reported in a daily newspaper of national
circulation. (Section 3.08.)
 
    Upon determination of the actual number of shares of Common Stock issuable
in accordance with the foregoing provisions, Jacor will publish such
determination in a daily newspaper of national circulation. (Section 3.08.)
 
    Jacor's right to purchase LYONs, in whole or in part, with Common Stock is
subject to the satisfaction by Jacor of various conditions, including: (i) the
registration of the Common Stock under the Securities Act and the Exchange Act,
if required and (ii) any necessary qualification or registration under
applicable state securities law or the availability of an exemption from such
qualification and registration. If such conditions are not satisfied with
respect to a Holder or Holders prior to the close of business on the Purchase
Date, Jacor will pay, without further notice, the Purchase Price of the LYONs of
such Holder or Holders entirely in cash. (Section 3.08.) See "Certain United
States Federal Income Tax Consequences-- Other Disposition." Jacor may not
change the form of consideration (or components or percentages of components
thereof) to be paid once Jacor has given its Jacor Notice to Holders of LYONs
except as described in the second sentence of this paragraph. (Section 3.08.)
 
    Jacor will comply with the provisions of Rule 13e-4, Rule 14e-1, and any
other tender offer rules under the Exchange Act which may then be applicable and
will file Schedule 13E-4 or any other schedule required thereunder in connection
with any offer by Jacor to purchase LYONs at the option of Holders. (Section
3.13.)
 
    Payment of the Purchase Price for a LYON for which a Purchase Notice has
been delivered and not validly withdrawn is conditioned upon delivery of such
LYON (together with necessary endorsements) to the Paying Agent or an office or
agency maintained by Jacor for such purpose in the Borough of Manhattan, The
City of New York, at any time (whether prior to, on or after the Purchase Date)
after delivery of such Purchase Notice. (Section 3.08.) Payment of the Purchase
Price for such LYON will be made promptly following the later of the business
day following the Purchase Date and the time of delivery of such LYON. (Section
3.10.) If the Paying Agent holds, in accordance with the terms of the Indenture,
money or securities sufficient to pay the Purchase Price of such LYON on the
business day following the Purchase Date, then, on and after the Purchase Date,
such LYON will cease to be outstanding and Original Issue Discount on such LYON
will cease to accrue and will be deemed paid, whether or not such LYON is
delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Purchase Price upon delivery of
such LYON). (Section 2.08.)
 
    Jacor's ability to purchase LYONs with cash is limited by the terms of the
Credit Facility and JCC's senior subordinated indebtedness and may be limited by
the terms of any other then-existing borrowing
 
                                      S-44
<PAGE>
agreements. Jacor is a holding company and the Credit Facility significantly
restricts the payment of dividends and the making of loans, advances and other
payments by subsidiaries of Jacor to Jacor. No LYONs may be purchased at the
option of Holders for cash if there has occurred and is continuing an Event of
Default described under "Events of Default; Notice and Waiver" below (other than
a default in the payment of the Purchase Price with respect to such LYONs).
(Section 3.10.)
 
CHANGE IN CONTROL PERMITS PURCHASE OF LYONS AT THE OPTION OF THE HOLDER
 
    In the event of any Change in Control (as defined below) of Jacor occurring
on or prior to February   , 2003, each Holder of LYONs will have the right, at
the Holder's option, subject to the terms and conditions of the Indenture which
will be contained in the notice described in the following paragraph, to require
Jacor to purchase all or any part (provided that the principal amount at
maturity must be $1,000 or an integral multiple thereof) of the Holder's LYONs
on the date that is 35 business days after the occurrence of such Change in
Control (the "Change in Control Purchase Date") at a cash price equal to the
Issue Price plus accrued Original Issue Discount through the Change in Control
Purchase Date (the "Change in Control Purchase Price"). (Section 3.09 and Form
of LYON, paragraph 6.) Holders will not have any right to require Jacor to
purchase LYONs in the event of any Change in Control of Jacor occurring after
February   , 2003.
 
    Within 15 business days after the Change in Control, Jacor shall mail to the
Trustee and to each Holder (and to beneficial owners as required by applicable
law) a notice regarding the Change in Control, which notice shall state, among
other things: (i) the date of such Change in Control and, briefly, the events
causing such Change in Control, (ii) the date by which the Change in Control
Purchase Notice (as defined below) must be given, (iii) the Change in Control
Purchase Date, (iv) the Change in Control Purchase Price, (v) the name and
address of the Paying Agent and the Conversion Agent, (vi) the Conversion Rate
and any adjustments thereto, (vii) that LYONs with respect to which a Change in
Control Purchase Notice is given by the Holder may be converted into shares of
Common Stock only if the Change in Control Purchase Notice has been withdrawn by
the Holder in accordance with the procedures stated in the notice, (viii) the
procedures that Holders must follow to exercise these rights, (ix) the
procedures for withdrawing a Change in Control Purchase Notice, (x) that Holders
who want to convert LYONs must satisfy the requirements set forth in paragraph 9
of the LYONs and (xi) briefly, the conversion rights of Holders of LYONs. Jacor
will cause a copy of such notice to be published in a daily newspaper of
national circulation. (Section 3.09.)
 
    To exercise the purchase right, the Holder must deliver written notice of
the exercise of such right (a "Change in Control Purchase Notice") to the Paying
Agent or an office or agency maintained by Jacor for such purpose in the Borough
of Manhattan, The City of New York, prior to the close of business on the Change
in Control Purchase Date. The Change in Control Purchase Notice shall state (i)
the certificate numbers of the LYONs to be delivered by the Holder thereof for
purchase by Jacor; (ii) the portion of the principal amount at maturity of LYONs
to be purchased, which portion must be $1,000 or an integral multiple thereof
and (iii) that such LYONs are to be purchased by Jacor pursuant to the
applicable provisions of the LYONs. (Section 3.09.)
 
    Any Change in Control Purchase Notice may be withdrawn by the Holder by a
written notice of withdrawal delivered to the Paying Agent prior to the close of
business on the Change in Control Purchase Date. The notice of withdrawal shall
state the principal amount at maturity and the certificate numbers of the LYONs
as to which the withdrawal notice relates and the principal amount at maturity,
if any, which remains subject to a Change in Control Purchase Notice. (Section
3.10.)
 
    Payment of the Change in Control Purchase Price for a LYON for which a
Change in Control Purchase Notice has been delivered and not withdrawn is
conditioned upon delivery of such LYON (together with necessary endorsements) to
the Paying Agent or an office or agency maintained by Jacor for such purpose in
the Borough of Manhattan, The City of New York, at any time (whether prior to,
on or
 
                                      S-45
<PAGE>
after the Change in Control Purchase Date) after the delivery of such Change in
Control Purchase Notice. (Section 3.09.) Payment of the Change in Control
Purchase Price for such LYON will be made promptly following the later of the
business day following the Change in Control Purchase Date and the time of
delivery of such LYON. (Section 3.10.) If the Paying Agent holds, in accordance
with the terms of the Indenture, money sufficient to pay the Change in Control
Purchase Price of such LYON on the business day following the Change in Control
Purchase Date, then, on and after the Change in Control Purchase Date, such LYON
will cease to be outstanding and Original Issue Discount on such LYON will cease
to accrue and will be deemed paid, whether or not such LYON is delivered to the
Paying Agent, and all other rights of the Holder shall terminate (other than the
right to receive the Change in Control Purchase Price upon delivery of such
LYON). (Section 2.08 and Form of LYON, paragraph 6.)
 
    Under the Indenture, a "Change in Control" of Jacor is deemed to have
occurred at such time as (i) any person (as the term "person" is used in Section
13(d)(3) or Section 14(d)(2) of the Exchange Act) other than Zell/Chilmark Fund
L.P. ("Zell/Chilmark"), Jacor, any subsidiary of Jacor, or any employee benefit
plan of either Jacor or any Subsidiary of Jacor, files a Schedule 13D or 14D-1
under the Exchange Act (or any successor schedule, form or report) disclosing
that such person has become the beneficial owner of 50% or more of the Common
Stock or other capital stock of Jacor into which such Common Stock is
reclassified or changed, with certain exceptions or (ii) there shall be
consummated any consolidation or merger of Jacor (a) in which Jacor is not the
continuing or surviving corporation or (b) pursuant to which the Common Stock
would be converted into cash, securities or other property, in each case, other
than a consolidation or merger of Jacor in which the holders of Common Stock
immediately prior to the consolidation or merger own, directly or indirectly, at
least a majority of Common Stock of the continuing or surviving corporation
immediately after the consolidation or merger. The Indenture does not permit the
Board of Directors to waive Jacor's obligation to purchase LYONs at the option
of a Holder in the event of a Change in Control of Jacor. (Section 3.09.) A
Change of Control under the LYONs constitutes an event of default under the
Credit Facility. See "Description of Indebtedness -- Credit Facility" in the
accompanying Prospectus.
 
    In addition, a change of control under any of JCC's senior subordinated
indebtedness, the LYONs due 2011 or the LYONs will result in a default under the
Credit Facility. Additionally, unless JCC is successful in seeking consents from
its lenders under the Credit Facility to consummate change of control repurchase
offers for its senior subordinated indebtedness, the LYONs due 2011 or the
LYONs, or JCC is successful in refinancing such borrowings, such event of
default under the Credit Facility would constitute an event of default under
such senior subordinated indebtedness, the LYONs due 2011 and the LYONs. Such
events of default could result in the immediate acceleration of JCC's senior
subordinated indebtedness, the LYONs due 2011 and the LYONs. As a result,
differences in the definitions of change of control for JCC's senior
subordinated indebtedness, the LYONs due 2011 and the LYONs will not result in a
difference in the effect on JCC or the respective holders other than where the
lenders under the Credit Facility have waived such event of default. In the
event of such waiver there could be a change of control under JCC's senior
subordinated indebtedness which would not result in a change of control under
the LYONs due 2011 and the LYONs or VICE VERSA. See "Description of
Indebtedness" in the accompanying Prospectus.
 
    Jacor will comply with the provisions of Rule 13e-4, Rule 14e-1 and any
other tender offer rules under the Exchange Act which may then be applicable,
and will file Schedule 13E-4 or any other schedule required thereunder in
connection with any offer by Jacor to purchase LYONs at the option of the
Holders thereof upon a Change in Control. (Section 3.13.) The Change in Control
purchase feature of the LYONs may in certain circumstances make more difficult
or discourage a takeover of Jacor and, thus, the removal of incumbent
management. The Change in Control purchase feature, however, is not the result
of management's knowledge of any specific effort to accumulate shares of Common
Stock or to obtain control of Jacor by means of a merger, tender offer,
solicitation or otherwise, or part of a plan by management to adopt a series of
anti-takeover provisions. Instead, the Change in Control purchase feature
 
                                      S-46
<PAGE>
is a standard term contained in other LYONs offerings that have been marketed by
the Underwriter, and the terms of such feature result from negotiations between
Jacor and the Underwriter.
 
    Jacor could, in the future, enter into certain transactions, including
certain recapitalizations of Jacor, that would not consititute a Change in
Control with respect to the Change in Control purchase feature of the LYONs, but
that would increase the amount of indebtedness outstanding at such time. If a
Change in Control were to occur, there can be no assurance that Jacor would have
funds sufficient to pay the Change in Control Purchase Price for all of the
LYONs that might be delivered by Holders seeking to exercise the purchase right
since Jacor might also be required to prepay certain other indebtedness having
financial covenants with change of control provisions in favor of the holders
thereof. In addition, a Change in Control under the Indenture will result in a
default under the Credit Facility, and thereby could cause the acceleration of
the maturity of the indebtedness represented by JCC's senior subordinated
indebtedness. In addition, Jacor's ability to purchase LYONs with cash may be
limited by the terms of its then-existing borrowing agreements. No LYONs may be
purchased pursuant to the provisions described above if there has occurred and
is continuing an Event of Default described under "Events of Default; Notice and
Waiver" below (other than a default in the payment of the Change in Control
Purchase Price with respect to such LYONs). (Section 3.10.)
 
MERGERS AND SALES OF ASSETS BY JACOR
 
    Jacor may consolidate with or merge into, or transfer or lease its assets
substantially as an entirety to any corporation organized under the laws of any
domestic jurisdiction, provided that (i) the successor corporation assumes
Jacor's obligations on the LYONs and under the Indenture and (ii) after giving
effect to the transaction no Event of Default, and no event which, after notice
or lapse of time would become an Event of Default, shall have occurred and be
continuing. (Section 5.01.) Certain of the foregoing transactions, if they occur
on or prior to February   , 2003, could constitute a Change in Control of Jacor
permitting each Holder to require Jacor to purchase the LYONs of such Holder as
described above. (Section 3.09.)
 
EVENTS OF DEFAULT; NOTICE AND WAIVER
 
    The Indenture provides that, if an Event of Default specified therein shall
have happened and be continuing, either the Trustee or the Holders of not less
than 25% in aggregate principal amount at maturity of the LYONs then outstanding
may declare the Issue Price of the LYONs plus Original Issue Discount on the
LYONs accrued through the date of default (in the case of an Event of Default
specified in (i) or (ii) of the following paragraph) or to the date of such
declaration (in the case of an Event of Default specified in (iii) or (iv) of
the following paragraph) on all the LYONs to be immediately due and payable. In
the case of certain events of bankruptcy or insolvency, the Issue Price of the
LYONs plus the Original Issue Discount accrued thereon to the occurrence of such
event shall automatically become and be immediately due and payable. Under
certain circumstances, the Holders of a majority in aggregate principal amount
at maturity of the outstanding LYONs may rescind any such acceleration with
respect to the LYONs and its consequences. (Sections 6.02 and 6.04.) Interest
shall, to the extent permitted by law, accrue and be payable on demand upon a
default in the payment of principal amount at maturity, Issue Price, accrued
Original Issue Discount, Redemption Price, Purchase Price, Change in Control
Purchase Price with respect to any LYON and such interest shall be compounded
semi-annually. (Section 6.01.) The accrual of such interest on overdue amounts
shall be in lieu of, and not in addition to, the continued accrual of Original
Issue Discount. (Form of LYON, paragraph 1.)
 
    Under the Indenture, Events of Default include: (i) default in payment of
the principal amount at maturity, Issue Price, accrued Original Issue Discount,
Redemption Price, Purchase Price or Change in Control Purchase Price with
respect to any LYON, when the same becomes due and payable (whether or not such
payment is prohibited by the provisions of the Indenture); (ii) failure by Jacor
to deliver shares of Common Stock (or cash in lieu of a fractional share of
Common Stock) when such Common Stock (or cash
 
                                      S-47
<PAGE>
in lieu of a fractional share of Common Stock) is required to be delivered
following conversion of a LYON and continuance of such default for 10 days;
(iii) failure by Jacor to comply with any of its other agreements in the LYONs
or the Indenture upon the receipt by Jacor of notice of such default from the
Trustee or from Holders of not less than 25% in aggregate principal amount at
maturity of the LYONs then outstanding and Jacor's failure to cure such default
within 60 days after receipt by Jacor of such notice; and (iv) default (A) in
the payment of any principal on any debt for borrowed money of Jacor or any
subsidiary of Jacor (excluding any non-recourse debt), in an aggregate principal
amount in excess of $10.0 million, that results in such debt becoming or being
declared due and payable prior to the date on which it would otherwise become
due and payable, unless (x) such acceleration or action to enforce payment, as
the case may be, has been rescinded or annulled, (y) such debt has been
discharged or (z) a sum sufficient to discharge in full such debt has been
deposited in trust by or on behalf of Jacor, in each case, within a period of 10
days after there has been given, by registered or certified mail, to Jacor by
the Trustee or to Jacor and the Trustee by the Holders of at least 25% in
aggregate principal amount at maturity of the LYONs, a written notice specifying
such default or defaults and stating that such notice is a "Notice of Default"
or (v) certain events of bankruptcy or insolvency. (Section 6.01.)
 
    The Trustee shall, within 90 days after the occurrence of any default, mail
to all Holders of the LYONs notice of all defaults of which the Trustee shall be
aware, unless such defaults shall have been cured or waived before the giving of
such notice; provided, that the Trustee may withhold such notice as to any
default other than a payment default, if it determines in good faith that
withholding the notice is in the interests of the Holders. (Section 6.12.)
 
    The Holders of a majority in aggregate principal amount at maturity of the
outstanding LYONs may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee, provided that such direction shall not be in
conflict with any law or the Indenture and subject to certain other limitations.
(Section 6.05.) The Trustee may refuse to perform any duty or exercise any right
or power or extend or risk its own funds or otherwise incur any financial
liability unless it receives indemnity satisfactory to it against any loss,
liability or expense. (Section 7.01.) No Holder of any LYON will have any right
to pursue any remedy with respect to the Indenture or the LYONs, unless (i) such
Holder shall have previously given the Trustee written notice of a continuing
Event of Default; (ii) the Holders of at least 25% in aggregate principal amount
at maturity of the outstanding LYONs shall have made a written request to the
Trustee to pursue such remedy; (iii) such Holder or Holders shall have offered
to the Trustee reasonable security or indemnity against any loss, liability or
expense satisfactory to it; (iv) the Trustee shall have failed to comply with
the request within 60 days after receipt of such notice, request and offer of
security or indemnity and (v) the Holders of a majority in aggregate principal
amount at maturity of the outstanding LYONs shall not have given the Trustee a
direction inconsistent with such request within 60 days after receipt of such
request. (Section 6.06.)
 
    The right of any Holder: (a) to receive payment of the principal amount at
maturity, Issue Price, accrued Original Issue Discount, Redemption Price,
Purchase Price, Change in Control Purchase Price or interest, if any, in respect
of the LYONs held by such Holder on or after the respective due dates expressed
in the LYONs or as of any Redemption Date, (b) to convert such LYONs or (c) to
bring suit for the enforcement of any such payment on or after such respective
dates or the right to convert, shall not be impaired or adversely affected
without such Holder's consent. (Section 6.07.)
 
    The Holders of a majority in aggregate principal amount at maturity of LYONs
at the time outstanding may waive any existing default and its consequences
except (i) any default in any payment on the LYONs, (ii) any default with
respect to the conversion rights of the LYONs or (iii) any default in respect of
certain covenants or provisions in the Indenture which may not be modified
without the consent of the Holder of each LYON as described in "Modification"
below. When a default is waived, it is deemed cured and shall cease to exist,
but no such waiver shall extend to any subsequent or other default or impair any
consequent right. (Section 6.04.)
 
                                      S-48
<PAGE>
    Jacor will be required to furnish to the Trustee annually a statement as to
any default by Jacor in the performance and observance of its obligations under
the Indenture. In addition, Jacor shall file with the Trustee written notice of
the occurrence or any default or Event of Default within five business days of
its becoming aware of such default or Event of Default. (Section 4.03.)
 
MODIFICATION
 
    Modification and amendment of the Indenture or the LYONs may be effected by
Jacor and the Trustee with the consent of the Holders of not less than a
majority in aggregate principal amount at maturity of the LYONs then
outstanding. However, without the consent of each Holder affected thereby, no
amendment may, among other things, (i) reduce the principal amount at maturity,
Issue Price, Purchase Price, Change in Control Purchase Price or Redemption
Price with respect to any LYON, or extend the stated maturity of any LYON or
alter the manner or rate of accrual of Original Issue Discount or interest, or
make any LYON payable in money or securities other than that stated in the LYON;
(ii) make any reduction in the principal amount at maturity of LYONs whose
Holders must consent to an amendment or any waiver under the Indenture or modify
the Indenture provisions relating to such amendments or waivers; (iii) make any
change that adversely affects the right to convert any LYON or the right to
require Jacor to purchase a LYON or (iv) impair the right to institute suit for
the enforcement of any payment with respect to, or conversion of, the LYONs.
(Section 9.02.)
 
    Without the consent of any Holder of LYONs, Jacor and the Trustee may amend
the Indenture to (i) cure any ambiguity, defect or inconsistency, provided,
however, that such amendment does not materially adversely affect the rights of
any Holder, (ii) provide for the assumption by a successor to the Company of the
obligations of Jacor under the Indenture, (iii) provide for uncertificated LYONs
in addition to certificated LYONs, as long as such uncertificated LYONs are in
registered form for United States federal income tax purposes, (iv) make any
change that does not adversely affect the rights of any Holder of LYONs or (v)
add to the covenants or obligations of Jacor under the Indenture or surrender
any right, power or option conferred by the Indenture on Jacor. (Section 9.01.)
 
DISCHARGE OF THE INDENTURE
 
    Jacor may satisfy and discharge its obligations under the Indenture by
delivering to the Trustee for cancellation all outstanding LYONs or by
depositing with the Trustee, the Paying Agent or the Conversion Agent, if
applicable, after the LYONs have become due and payable, whether at stated
maturity, or any Redemption Date, or any Purchase Date, a Change of Control
Purchase Date, or upon conversion or otherwise, cash or Common Stock (as
applicable under the terms of the Indenture) sufficient to pay all of the
outstanding LYONs and paying all other sums payable under the Indenture by
Jacor. (Article 8.)
 
NO RECOURSE AGAINST OTHERS
 
    The Indenture provides that a director, officer, employee or stockholder, as
such, of Jacor shall not have any liability for any obligations of Jacor under
the LYONs or the Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation.
 
LIMITATIONS OF CLAIMS IN BANKRUPTCY
 
    If a bankruptcy proceeding is commenced in respect of Jacor, under Title 11
of the United States Code, the claim of the Holder of a LYON may be limited to
the Issue Price of the LYON plus that portion of the Original Issue Discount
that is deemed to have accrued from the date of issue to the commencement of the
proceeding. In addition, the Holders of the LYONs will be effectively
subordinated to all indebtedness and other obligations of Jacor's subsidiaries.

TAXATION OF LYONS
 
    See "Certain United States Federal Income Tax Considerations" for a
discussion of certain United States Federal income tax aspects which will apply
to Holders of LYONs.
 
INFORMATION CONCERNING THE TRUSTEE
 
    The Bank of New York is the Trustee, Registrar, Paying Agent and Conversion
Agent under the Indenture.
 
BOOK-ENTRY, DELIVERY AND FORM
 
    Except as set forth below, the LYONs will initially be issued in the form of
one or more registered LYONs in global form (the "Global LYONs"). Each Global
LYON will be deposited on the date of the closing of the sale of the LYONs (the
"Closing Date") with, or on behalf of, The Depository Trust Company (the
"Depositary") and registered in the name of Cede & Co. (the Depositary's
partnership nominee).
 
    The Depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depositary holds securities that its participants ("Participants")
deposit with the Depositary. The Depositary also facilitates the settlement
among Participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in
Participants' accounts, thereby eliminating the need for physical movement of
securities certificates. Direct Participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations ("Direct Participants"). The Depositary is owned by a number of
its Direct Participants and by the NYSE, the American Stock Exchange, Inc. and
the National Association of Securities Dealers, Inc. Access to the the
Depositary system of the Depositary is also available to others such as
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to the Depositary and
its Participants are on file with the SEC.
 
    Jacor expects that pursuant to procedures established by the Depositary (i)
upon deposit of the Global LYONs, the Depositary will credit the accounts of
Participants designated by the Underwriter with an interest in the Global LYON
and (ii) ownership of the LYONs evidenced by the Global LYON will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depositary (with respect to the interests of Participants),
the Participants and the Indirect Participants. The laws of some states require
that certain persons take physical delivery in definitive form of securities
that they own and that security interests in negotiable instruments can only be
perfected by delivery of certificates representing the instruments.
Consequently, the ability to transfer LYONs evidenced by the Global LYON will be
limited to such extent.
 
    To facilitate subsequent transfers, all LYONs deposited by Participants with
the Depositary are registered in the name of Depositary's partnership nominee,
Cede & Co. The deposit of the LYONs with the Depositary and their registration
in the name of Cede & Co. effect no change in beneficial ownership. The
Depositary has no knowledge of the actual beneficial owners of the LYONs. The
Depositary's records reflect only the identity of the Direct Participants to
whose accounts such LYONs are credited, which may or may not be the beneficial
owners of the LYONs. The Participants will remain responsible for keeping
account of their holdings on behalf of their customers.
 
    Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to beneficial
 
                                      S-50
<PAGE>
owners of the LYONs will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.
 
    So long as the Depositary or its nominee is the registered owner of a LYON,
the Depositary or such nominee, as the case may be, will be considered the sole
owner or holder of the LYONs represented by the Global LYON for all purposes
under the Indenture. Except as provided below, owners of beneficial interests in
a Global LYON will not be entitled to have LYONs represented by such Global LYON
registered in their names, will not receive or be entitled to receive physical
delivery of Certificated LYONs, and will not be considered the owners or holders
thereof under the Indenture for any purpose, including with respect to the
giving of any directions, instructions or approvals to the Trustee thereunder.
As a result, the ability of a person having a beneficial interest in LYONs
represented by a Global LYON to pledge such interest to persons or entities that
do not participate in the Depositary's system, or to otherwise take actions with
respect to such interest, may be affected by the lack of a physical certificate
evidencing such interest.
 
    Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of LYONs by the Depositary, or for maintaining, supervising or reviewing any
records of the Depositary relating to such LYONs.
 
    Payments with respect to the principal of, premium, if any, interest on, any
LYON represented by a Global LYON registered in the name of the Depositary or
its nominee on the applicable record date will be payable by the Trustee to or
at the direction of the Depositary or its nominee in its capacity as the
registered Holder of the Global LYON representing such LYONs under the
Indenture. Under the terms of the Indenture, Jacor and the Trustee may treat the
persons in whose names the LYONs, including the Global LYONs, are registered as
the owners thereof for the purpose of receiving such payments and for any and
all other purposes whatsoever. Consequently, neither Jacor nor the Trustee has
or will have any responsibility or liability for the payment of such amounts to
beneficial owners of LYONs (including principal, premium, if any or interest),
or to immediately credit the accounts of the relevant Participants with such
payment, in amounts proportionate to their respective holdings in principal
amount of beneficial interests in the Global LYON as shown on the records of the
Depositary. Payments by the Participants and the Indirect Participants to the
beneficial owners of LYONs will be governed by standing instructions and
customary practice and will be the responsibility of the Participants or the
Indirect Participants.
 
    CERTIFICATED NOTES
 
    If (i) Jacor notifies the Trustee in writing that the Depositary is no
longer willing or able to act as a depositary and Jacor is unable to locate a
qualified successor within 90 days or (ii) Jacor, at its option, notifies the
Trustee in writing that it elects to cause the issuance of LYONs in definitive
form under the Indenture, then, upon surrender by the Depositary of the Global
LYONs, Certificated LYONs will be issued to each person that the Depositary
identifies as the beneficial owner of the LYONs represented by Global LYONs. In
addition, subject to certain conditions, any person having a beneficial interest
in a Global LYON may, upon request to the Trustee, exchange such beneficial
interest for LYONs in the form of Certificated LYONs. Upon any such issuance,
the Trustee is required to register such Certificated LYONs in the name of such
person or persons (or the nominee of any thereof), and cause the same to be
delivered thereto.
 
    Neither Jacor nor the Trustee shall be liable for any delay by the
Depositary or any Participant or Indirect Participant in identifying the
beneficial owners of the LYONs, and Jacor and the Trustee may conclusively rely
on, and shall be protected in relying on, instructions from the Depositary for
all purposes (including with respect to the registration and delivery, and the
respective principal amounts, of the LYONs to be issued).
 
    The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that Jacor
believes to be reliable. Jacor will have no responsibility for the
 
                                      S-51
<PAGE>
performance by the Depositary or its Participants of their respective
obligations as described hereunder or under the rules and procedures governing
their respective operations.
 
SAME-DAY FUNDS SETTLEMENT AND PAYMENT
 
    The Indenture will require that payments in respect of the LYONs represented
by the Global LYONs (including principal, premium, if any, and interest) be made
by wire transfer of immediately available funds to the accounts specified by the
Depositary. With respect to LYONs represented by Certificated LYONs, Jacor will
make all payments of principal, premium, if any, and interest, by mailing a
check to each such Holder's registered address. The LYONs will trade in the
Depositary's Same-Day Funds Settlement System until maturity, or until the LYONs
are issued in certificated form, and secondary market trading activity in the
LYONs will therefore be required by the Depositary to settle in immediately
available funds. No assurance can be given as to the effect, if any, of
settlement in immediately available funds on trading activity in the LYONs.

    For a general description of the Indebtedness of Jacor, see "Description of
Indebtedness" in the accompanying Prospectus.
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summary of United States Federal income tax considerations is
based on current law, regulations and judicial and administrative
interpretations thereof, all of which are subject to change. The tax treatment
of a Holder of a LYON may vary depending upon his particular situation. Certain
Holders (including insurance companies, tax-exempt organizations, individual
retirement and other tax-deferred accounts, financial institutions,
broker-dealers, foreign corporations and individuals who are not citizens or
residents of the United States) may be subject to special rules not discussed
below. This summary does not discuss the tax considerations of subsequent
purchasers of LYONs and is limited to investors who hold LYONs as capital
assets. Each purchaser of LYONs should consult his tax advisor as to the
particular tax consequences to him of acquiring, holding, converting or
otherwise disposing of the LYONs, including the applicability and the effect of
any state, local or foreign tax laws and recent changes in applicable tax laws.
 
    Jacor has been advised by its counsel, Graydon, Head & Ritchey, that in
counsel's opinion, based on current laws, regulations and administrative and
judicial standards, all of which are subject to change, the LYONs will be
treated as indebtedness for United States Federal income tax purposes. Counsel
has further advised Jacor that it is counsel's opinion that, while the following
does not purport to discuss all tax matters relating to the LYONs, based upon
the LYONs being treated as indebtedness, the following are the material federal
income tax consequences of the LYONs, subject to the qualifications set forth
above.
 
ORIGINAL ISSUE DISCOUNT
 
    The LYONs are being issued at a substantial discount from their principal
amount at maturity. For United States Federal income tax purposes, the
difference between the issue price (the initial price at which a LYON is sold)
and the stated principal amount at maturity of each LYON constitutes original
issue discount ("Original Issue Discount"). Holders of the LYONs will be
required to include Original Issue Discount in income periodically over the term
of the LYONs before receipt of the cash or other payment attributable to such
income.
 
    For United States Federal income tax purposes, each Holder of a LYON must
include in gross income a portion of the Original Issue Discount in each taxable
year during which the LYON is held in an amount equal to the Original Issue
Discount that accrues on the LYON during such period, determined by using a
constant yield to maturity method. The Original Issue Discount included in
income for each year will be calculated under a compounding formula that will
result in the allocation of less Original Issue Discount to the earlier years of
the term of the LYON and more Original Issue Discount to later years. For the
approximate cumulative total amount of the Original Issue Discount accrued
annually, see the chart under "Description of LYONs--Redemption of LYONs at the
Option of Jacor." Any amount included in income as Original Issue Discount will
increase a Holder's tax basis in the LYON.
 
                                      S-53
<PAGE>
CONVERSION
 
    A Holder's conversion of a LYON into Common Stock is not a taxable event
(except with respect to cash received in lieu of a fractional share of Common
Stock). The Holder's tax basis in the Common Stock received on conversion of a
LYON will be the same as the Holder's adjusted tax basis in the LYON at the time
of conversion (exclusive of any basis allocable to a fractional share of Common
Stock), and the holding period of the Common Stock received on conversion will
include the holding period of the LYON converted, except that it is possible
that the Internal Revenue Service may argue that the holding period of the
Common Stock allocable to accrued Original Issue Discount will commence on the
date of the conversion.
 
OTHER DISPOSITION
 
    If a Holder elects to exercise his option to tender a LYON to Jacor on a
Purchase Date and Jacor issues Common Stock in satisfaction of the Purchase
Price, such exchange will be treated the same as a conversion.
 
    If a Holder elects to exercise his option to tender a LYON to Jacor on a
Purchase Date and Jacor delivers a combination of cash and Common Stock in
satisfaction of the Purchase Price, such Holder will recognize gain (but not
loss) to the extent that the cash and the value of the Common Stock received
exceeds the Holder's adjusted tax basis in the LYON, but in no event will any
such gain exceed the amount of cash received. A Holder's basis in the Common
Stock received would be the same as the Holder's basis in the LYON put to Jacor
by the Holder (exclusive of any basis allocable to a fractional share),
decreased by the amount of cash (other than cash received in lieu of a
fractional share), received and increased by the amount of gain, if any,
recognized by the Holder (other than gain with respect to a fractional share).
The holding period for the Common Stock received in the exchange will include
the holding period for the LYON tendered except that the Internal Revenue
Service may argue that the holding period of the Common Stock allocable to
accrued Original Issue Discount will commence on the Purchase Date.
 
    If a Holder elects to exercise his option to tender a LYON to Jacor on a
Purchase Date or a Change in Control Purchase Date and the Holder receives cash,
such a tender will be a taxable sale. The Holder will recognize gain or loss
upon the sale, to the extent that the cash received in satisfaction of the
Purchase Price or the Change in Control Purchase Price is more or less than the
Holder's adjusted tax basis in the tendered LYON.
 
    If a Holder sells a LYON in the market, it will be a taxable sale with the
same results as a tender to Jacor with a payment in cash.
 
    Under the recently enacted Taxpayer Relief Act of 1997, net capital gain
(I.E., generally, capital gain in excess of capital loss) recognized by a Holder
upon the disposition of a LYON that has been held for more than 18 months will
generally be subject to tax at a rate not to exceed 20%. Net capital gain
recognized by a Holder upon the disposition of a LYON that has been held for
more than 12 months but for not more than 18 months will continue to be subject
to tax at a rate not to exceed 28% and capital gain recognized from the
disposition of a LYON that has been held for 12 months or less will continue to
be subject to tax at ordinary income tax rates. In addition, capital gain
recognized by a corporate taxpayer will continue to be subject to tax at the
ordinary income tax rates applicable to corporations.
 
CONSTRUCTIVE DIVIDEND
 
    If at any time Jacor makes a distribution of property to its shareholders
that would be taxable to such shareholders as a dividend for United States
Federal income tax purposes and, in accordance with the anti-dilution provisions
of the LYONs, the Conversion Rate of the LYONs is increased, such increase may
be deemed to be the payment of a taxable dividend to Holders of the LYONs. For
example, an increase in the Conversion Rate in the event of distributions of
evidences of indebtedness or assets of Jacor or an increase in the event of an
Extraordinary Cash Dividend will generally result in deemed dividend treatment
to Holders of the LYONs, but generally an increase in the event of stock
dividends or the distribution of rights to subscribe for Common Stock will not.

                                  UNDERWRITING
 
    Subject to the terms and conditions set forth in a purchase agreement (the
"Purchase Agreement"), Jacor has agreed to sell to Merrill Lynch, Pierce, Fenner
& Smith Incorporated (the "Underwriter"), and the Underwriter has agreed to
purchase from Jacor, $     million aggregate principal amount at maturity of the
LYONs. The Underwriter has advised Jacor that it proposes to offer the LYONs
directly to the public at the initial offering price set forth on the cover page
of this Prospectus Supplement. After the initial public offering, the offering
price may be changed. The LYONs are offered subject to receipt and acceptance by
the Underwriter and to certain other conditions, including the right to reject
orders in whole or in part.
 
    Jacor has granted the Underwriter an option to purchase up to an additional
$            million aggregate principal amount at maturity of the LYONs, at the
initial public offering price less the underwriting discount plus accrued
Original Issue Discount solely to cover over-allotments, if any. Such option may
be exercised at any time for 30 days after the date of this Prospectus
Supplement.
 
    Jacor has agreed to indemnify the Underwriter against certain civil
liabilities, including liabilities under the Securities Act of 1933, or to
contribute to payments that the Underwriter may be required to make in respect
thereof. The Underwriter has agreed to pay certain expenses of Jacor in
connection with the offering estimated at $    .
 
    In connection with this Offering, the Underwriter and dealers may engage in
passive market making transactions in the LYONs due 2011 in accordance with Rule
103 of Regulation M promulgated by the Commission. In general, a passive market
maker may not bid for or purchase the LYONs due 2011 at a price that exceeds the
highest independent bid. In addition, the net daily purchases made by any
passive market maker generally may not exceed 30% of its average daily trading
volume in the LYONs due 2011 during a specified two month prior period, or 200
of the LYONs due 2011, whichever is greater. A passive market maker must
identify passive market making bids on the Nasdaq electronic inter-dealer
reporting system. Passive market making may stabilize or maintain the market
price of the LYONs due 2011 above independent market levels. Underwriters and
dealers are not required to engage in passive market making and may end passive
market making activities at any time.
 
    Jacor, its directors and executive officers and Zell/Chilmark have agreed
not to offer to sell, sell, distribute, grant any option to purchase or
otherwise dispose of, directly or indirectly, any shares of Common Stock or
securities convertible into, or exercisable or exchangeable for, shares of
Common Stock owned by them prior to the expiration of 120 days from the date of
this Prospectus Supplement, except (i) with the prior written consent of the
Underwriter, (ii) in the case of Jacor, for the issuance of shares of Common
Stock in connection with the conversion of the LYONs due 2011, the LYONs and
acquisition transactions in which the recipients of such shares are restricted
from selling such shares until after the expiration of 120 days from the date of
this Prospectus Supplement or upon the exercise of outstanding options, or the
grant of options to purchase shares of Common Stock under Jacor's stock option
plans, stock purchase plans and incentive stock plans, described in this
Prospectus Supplement or the accompanying Prospectus (by incorporation or
otherwise), and (iii) in the case of the directors and executive officers of
Jacor, for the exercise by such individuals of outstanding options and (iv) for
the sale of shares of Common Stock in the Common Stock Offering. In addition,
Jacor will inform certain former shareholders of Regent Communications, Inc. who
in the aggregate hold approximately 909,600 warrants to acquire approximately
102,500 shares of Common Stock (the "Regent Holders") that, for a period of 30
days from the date of this Prospectus Supplement, the Regent Holders may not
sell any of such shares or warrants pursuant to the shelf registration statement
currently in effect providing for the registration and distribution of such
shares and warrants. The Underwriter may, in its sole discretion and at any time
without prior notice, release all or any portion of the shares subject to these
"lock-up" agreements.
 
    Merrill Lynch, Pierce, Fenner & Smith Incorporated has previously marketed
(and anticipates continuing to market) securities of issuers under the trademark
"LYONs." The LYONs offered by Jacor
 
                                      S-55
<PAGE>
hereby contain certain terms and provisions that are different from such other
previously marketed LYONs, the terms and provisions of which also vary. See
"Description of LYONs."
 
    The distribution of this Prospectus Supplement and the accompanying
Prospectus and the offering and sale of the LYONs in certain jurisdictions may
be restricted by law. Persons into whose possession this Prospectus Supplement
and the accompanying Prospectus come are required by the Underwriter and Jacor
to inform themselves about and to observe any such restrictions. This Prospectus
Supplement and the accompanying Prospectus do not constitute, and may not be
used for or in connection with, an offer or solicitation by anyone in any
jurisdiction in which such offer or solicitation is not authorized or to any
person to whom it is unlawful to make such offer or solicitation.
 
    Until the distribution of the LYONs is completed, the rules of the
Commission may limit the ability of the Underwriter to bid for and purchase the
LYONs, the LYONs due 2011 and shares of the Common Stock. As an exemption to
these rules, the Underwriter is permitted to engage in certain transactions that
stabilize the price of the LYONs, the LYONs due 2011 and shares of Common Stock.
Such transactions consist of bids or purchases for the purpose of pegging,
fixing or maintaining the price of the LYONs, the LYONs due 2011 or shares of
Common Stock.
 
    If the Underwriter creates a short position in the LYONs in connection with
the Offering, (I.E., if it sells more LYONs than are set forth on the cover page
of this Prospectus Supplement), the Underwriter may reduce that short position
by purchasing LYONs in the open market. The Underwriter may also elect to reduce
any short position by exercising all or part of the over-allotment option
described above.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases.
 
    Neither Jacor nor the Underwriter makes any representation or prediction as
to the direction or magnitude of any effect that the transactions described
above may have on the price of the LYONs, the LYONs due 2011 or the Common
Stock. In addition, neither Jacor nor the Underwriter makes any representation
that the Underwriter will engage in such transactions or that such transactions,
once commenced, will not be discontinued without notice.
 
    In the ordinary course of its business, the Underwriter has engaged in, and
expects to engage in the future in, transactions with, and has performed, and
expects to perform in the future, services for, Jacor and Zell/Chilmark, and
their respective subsidiaries or affiliates for which it expects to receive
usual and customary fees.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
IN THIS PROSPECTUS OR THE ACCOMPANYING PROSPECTUS SUPPLEMENT, PROSPECTIVE
INVESTORS SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS BEFORE PURCHASING THE
SECURITIES OFFERED HEREBY.
 
    RISKS OF ACQUISITION STRATEGY.  Jacor intends to pursue growth through the
opportunistic acquisition of broadcasting companies, radio station groups,
individual radio stations and entities that provide programming and services to
radio station groups or individual radio stations. In this regard, Jacor
routinely reviews such acquisition opportunities. Jacor believes that currently
there are available a number of acquisition opportunities that would be
complementary to its business, although it may be more difficult to find
suitable transactions on terms acceptable to Jacor given the substantial
consolidation that has occurred in the radio broadcast industry since the
passage of the Telecom Act (as defined herein). Jacor cannot predict whether it
will be successful in pursuing such acquisition opportunities or what the
consequences of any such acquisition would be.
 
    The receipt of certain federal and state governmental or regulatory
approvals is required in order to consummate the acquisitions, including
approvals or waivers from the Federal Communications Commission (the "FCC"),
and, if certain criteria are met, the expiration of or termination of the
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR Act"), as enforced by the Antitrust Division
of the Department of Justice (the "Antitrust Division"). With regard to each
proposed acquisition, Jacor will use its reasonable best efforts to obtain such
approvals or waivers, but there can be no assurance that (i) the FCC will
approve the transfer of the broadcast licenses in connection with each proposed
transaction; (ii) the FCC or a court would affirm the FCC consent to the
proposed transaction if such review is undertaken; (iii) the HSR Act waiting
periods with respect to the various proposed transactions will expire without
objections being raised by either the Federal Trade Commission (the "FTC") or
the Antitrust Division that would not be eliminated without substantial changes
to the terms of the applicable proposed transactions; or (iv) Jacor will be
successful in consummating various proposed transactions in a timely manner or
on the terms originally agreed upon by the parties to the transactions.
 
    Jacor's acquisition strategy involves numerous risks, including difficulties
in the integration of operations and systems, the diversion of management's
attention from other business concerns and the potential loss of key employees
of acquired businesses. There can be no assurance that Jacor's management will
be able to manage effectively the resulting business or that such acquisitions
will benefit Jacor.
 
    In addition to the expenditure of capital relating to the Pending
Transactions, future acquisitions also may involve the expenditure of
significant funds, including the issuance of additional debt or equity.
Depending upon the nature, size and timing of future acquisitions, Jacor may be
required to raise additional financing. There is no assurance that such
additional financing will be available to Jacor on acceptable terms at the time
desired.
 
    NEED TO DEVELOP "STICK" PROPERTIES.  Jacor's business strategy relies, in
part, on improving the broadcast cash flow and ratings of its "stick" properties
(i.e. properties with insignificant broadcast cash flow and/or insignificant
ratings). In evaluating acquisition opportunities, Jacor seeks out "stick"
properties because Jacor believes that such radio stations provide the potential
for the greatest improvement in broadcast cash flow. Typically, Jacor will make
a substantial investment in a "stick" property to improve its programming
operations and/or signal. The Company currently has 99 "stick" properties, which
constitute more than half of the Company's portfolio of radio stations. There
can be no assurances that Jacor will be successful in improving the performance
of its "stick" properties, notwithstanding that substantial costs may be
incurred by Jacor in implementing this aspect of its business strategy.
 
    INCREASED ANTITRUST SCRUTINY.  Subsequent to the passage of the
Telecommunications Act of 1996 (the "Telecom Act") on February 8, 1996, the
radio broadcast industry has been subject to an increased amount of scrutiny by
the Antitrust Division. Such scrutiny caused Jacor to experience delays and
increased costs in
 
                                       4
<PAGE>
closing several transactions and also compelled changes in the proposed terms of
several acquisitions. Jacor could experience similar delays, increased costs,
and compelled changes in connection with future transactions.
 
    Although Jacor does not believe that antitrust considerations will adversely
affect Jacor's ability to successfully implement its business strategy, the
effects of the Antitrust Division's heightened level of scrutiny on the radio
broadcast industry and on Jacor are uncertain. There can be no assurance that
these concerns will not negatively impact Jacor.
 
    FCC REGULATION OF BROADCASTING INDUSTRY.  The broadcasting industry is
subject to extensive regulation by the FCC which, among other things, requires
approval for the issuance, renewal, transfer and assignment of broadcasting
station operating licenses, limits the number of broadcasting properties Jacor
may acquire and regulates the operations of broadcasting stations. Additionally,
in certain circumstances, the Communications Act of 1934, as amended (the
"Communications Act"), and FCC rules will operate to impose limitations on alien
ownership and voting of the capital stock of Jacor. Jacor's Certificate of
Incorporation permits the redemption of Common Stock from stockholders where
necessary to protect Jacor's regulatory licenses. See "Description of Capital
Stock." The FCC is considering changes to its rules in response to the Telecom
Act and other industry developments. There can be no assurance that any such
rule changes will not negatively impact Jacor's operations in the future.
 
    Jacor's business will be dependent upon maintaining its broadcasting
licenses issued by the FCC, which are issued currently for a maximum term of
eight years. Although it is rare for the FCC to deny a renewal application,
there can be no assurance that the pending or future renewal applications will
be approved, or that such renewals will not include conditions or qualifications
that could adversely affect Jacor'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 Jacor's business,
financial condition and results of operations.
 
    COMPETITION; BUSINESS RISKS.  Broadcasting is a highly competitive business.
Jacor's radio and television stations and syndicated radio programming compete
for audiences and advertising revenues directly with other radio and television
stations and other syndicated programs, as well as with other media, such as
newspapers, magazines, cable television, outdoor advertising, and direct mail,
within their respective geographic areas. Audience ratings and revenue shares
are subject to change and any adverse change in a particular geographic area
could have a material and adverse effect on the revenue of stations located in
that geographic area. Future operations are further subject to many variables
which could have an adverse effect upon Jacor's financial performance. These
variables include economic conditions, both generally and relative to the
broadcasting industry; shifts in population and other demographics; the level of
competition for advertising dollars with other radio stations, television
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. Although Jacor believes that each of its stations is
able to compete effectively in its respective broadcast area and that its
syndicated radio programs will continue to attract listeners and advertisers,
there can be no assurance that any such stations or syndicated programs will be
able to maintain or increase its current audience ratings and advertising
revenues.
 
    JACOR STRUCTURE.  A significant percentage of the assets and revenues of
Jacor are held by or derived from the operations of Jacor's subsidiaries. As a
result, trade creditors and other creditors of these subsidiaries may have a
claim that is structurally superior to that of the holders of indebtedness at
Jacor whose recourse to the assets and revenues of these subsidiaries derives
almost entirely from the equity interest therein of Jacor.
 
    The ability of Jacor and its subsidiaries to incur certain obligations is
limited by certain of the restrictive covenants contained in the Credit
Facility. Additionally, borrowings under the Credit Facility are secured by a
first priority lien on the capital stock of Jacor's subsidiaries, all
intercompany indebtedness owed to Jacor and have priority as to such collateral.
 
                                       5
<PAGE>
    In addition, Jacor's ability to make required principal and interest
payments with respect to Jacor's indebtedness depends on the earnings of its
subsidiaries. Since indebtedness of Jacor is an obligation of Jacor only (unless
otherwise guaranteed or agreed), Jacor's subsidiaries are not obligated or
required to pay any amounts due pursuant thereto or to make funds available
therefor in the form of dividends or advances to Jacor. In addition, the payment
of dividends and the making of loans, advances and other payments to Jacor by
its subsidiaries may be subject to statutory restrictions, are subject to
contractual restrictions in the Credit Facility and JCC's senior subordinated
indebtdness, are contingent upon the earnings of those subsidiaries and are
subject to various business and other considerations.
 
    SUBSTANTIAL LEVERAGE AND LIMITED FINANCIAL FLEXIBILITY.  Jacor's outstanding
indebtedness and its offering of any debt securities hereunder may have the
following important consequences: (i) significant interest expense and principal
repayment obligations resulting in substantial annual fixed charges; (ii)
significant limitations on Jacor's ability to obtain additional debt financing;
and (iii) increased vulnerability to adverse general economic and industry
conditions. In addition, Jacor's existing and anticipated credit facilities have
or will have a number of financial covenants, including interest coverage, debt
service coverage and a maximum ratio of debt to earnings before other expenses
(income), interest expenses, taxes, depreciation and amortization.
 
    SHARE OWNERSHIP BY ZELL/CHILMARK.  Zell/Chilmark Fund L.P. ("Zell/Chilmark")
holds approximately 13,349,720 (currently 29.3%) of the outstanding shares of
Jacor Common Stock and is Jacor's largest stockholder as of the date hereof. The
large share ownership of Zell/Chilmark may have the effect of discouraging
certain types of transactions involving an actual or potential change of control
of Jacor, including transactions in which the holders of Jacor Common Stock
might otherwise receive a premium for their shares over then-current market
prices.
 
    By the terms of its partnership agreement, Zell/Chilmark is to terminate on
or before July 1, 2000, subject to two one-year extensions in certain
circumstances. Accordingly, Zell/Chilmark will be required to sell its shares of
Jacor Common Stock or to distribute its shares of Jacor Common Stock to its
partners prior to or upon the termination of Zell/Chilmark. Subject to certain
restrictions under the Securities Act, Zell/ Chilmark is free to sell or
distribute shares of Jacor Common Stock from time to time for any reason. By
virtue of its current control of Jacor, Zell/Chilmark could sell large amounts
of Jacor Common Stock by causing Jacor to file a registration statement with
respect to such stock. In addition, Zell/Chilmark could sell its shares of Jacor
Common Stock without registration pursuant to Rule 144 under the Securities Act.
 
    Jacor can make no prediction as to the effect, if any, that such sales or
distributions of shares of Jacor Common Stock would have on the prevailing
market price. Sales or distributions of substantial amounts of Jacor Common
Stock, or the availability of such shares for sale or distribution, could
adversely affect prevailing market prices. Sales or distributions of Jacor
Common Stock by Zell/Chilmark could result in another person or entity becoming
a controlling stockholder of Jacor.
 
    LACK OF DIVIDENDS; RESTRICTIONS ON PAYMENTS OF DIVIDENDS.  Jacor has not
paid any dividends to its stockholders. Jacor intends to retain all available
earnings, if any, generated by its operations for the development and growth of
its business and does not anticipate paying any dividends on Jacor Common Stock
in the foreseeable future. In addition, the payment of dividends on the Jacor
Common Stock is restricted under Jacor's credit facilities.
 
    KEY PERSONNEL.  Jacor's business is dependent upon the performance of
certain key employees, including its Chief Executive Officer and its President.
Jacor also employs or independently contracts with several on-air personalities
and hosts of syndicated radio programs with significant loyal audiences in their
respective broadcast areas. Jacor generally enters into long-term agreements
with its key on-air talent and program hosts to protect its interests in those
relationships, but there can be no assurance that all such individuals will
remain with Jacor or will retain their audiences.
 
    POTENTIAL NEGATIVE IMPACT OF OTHER SECURITIES ISSUANCES.  Jacor has
authorized for issuance up to 4,000,000 shares of undesignated preferred stock.
The Jacor Board of Directors has the authority, without
 
                                       6
<PAGE>
further vote or action by Jacor stockholders, to issue the undesignated shares
of Jacor Preferred Stock in one or more series and to fix all rights,
qualifications, preferences, privileges, limitations and restrictions of each
such series, including dividend rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
any series or the designation of such series. Although it currently has no plans
to do so, the Jacor Board of Directors, without stockholder approval, can issue
Jacor Preferred Stock with voting and conversion rights which would adversely
affect the voting power of the holders of Jacor Common Stock. In addition, the
issuance of Jacor Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of Jacor and could therefore have a negative
impact on the trading price of the Jacor Common Stock. Jacor may also issue
other types of securities in the future that may have the same or similar
negative effects as the undesignated preferred stock. See "Description of
Capital Stock."

       DESCRIPTION OF CONVERTIBLE DEBT SECURITIES AND JCC DEBT SECURITIES
 
    The Jacor Convertible Debt Securities are to be issued under an Indenture
(the "Jacor Indenture") between Jacor and a trustee to be identified in the
applicable Prospectus Supplement (the "Jacor Trustee"). The JCC Debt Securities
and the JCC Convertible Debt Securities are to be issued under an Indenture (the
"JCC Indenture") between JCC and a trustee to be identified in the applicable
Prospectus Supplement (the "JCC Trustee"). The Jacor Trustee and the JCC Trustee
may be the same trustee. The Jacor Indenture and the JCC Indenture are sometimes
collectively called the "Indentures." The terms of the Indentures will also be
governed by certain provisions of the Trust Indenture Act of 1939, as amended.
The following summary statements with respect to the JCC Debt Securities and the
Convertible Debt Securities do not purport to be complete and are subject to,
and are qualified in their entirety by reference to, the detailed provisions of
the Indentures. Although some of the following summary statements collectively
refer to Jacor, JCC, the Subsidiary Guarantors and other parties, such
statements concerning each party shall apply to each such party respectively and
the applicable Indentures, unless otherwise noted. Capitalized terms are defined
in the Indentures unless otherwise defined herein. Whenever any particular
section of the Indentures or any term defined therein is referred to, such
section or definition is incorporated herein by reference. A copy of the form of
Indentures is available upon request.
 
GENERAL
 
    The JCC Debt Securities and the Convertible Debt Securities offered hereby
will be limited to an aggregate initial offering price not to exceed
$500,000,000. The Jacor Indenture will not limit the amount of Jacor Convertible
Debt Securities which can be issued thereunder and will provide that additional
Jacor Convertible Debt Securities may be issued in one or more series thereunder
up to the aggregate principal amount which may be authorized from time to time
by Jacor's Board of Directors. The JCC Indenture will not limit the amount of
JCC Debt Securities or JCC Convertible Debt Securities which can be issued
thereunder and will provide that additional JCC Debt Securities or JCC
Convertible Debt Securities may be issued in one or more series thereunder up to
the aggregate principal amount which may be authorized from time to time by
JCC's Board of Directors. The Jacor Convertible Debt Securities, the JCC
Convertible Debt Securities and the JCC Debt Securities will be unsecured
obligations of Jacor or JCC, respectively, and to the extent as may be permitted
under Jacor's and JCC's then-existing loan agreements and indentures, will rank
either senior to or equally and ratably with all other unsecured indebtedness of
JCC. The Jacor Convertible Debt Securities, the JCC Convertible Debt Securities
and the JCC Debt Securities also may be subordinate, and junior in right of
payment to all Senior Debt, to the extent and in the manner set forth in the
respective Indenture. See "Subordination."
 
    The Jacor Convertible Debt Securities may be fully and unconditionally
guaranteed by JCC and may be further guaranteed fully and unconditionally,
jointly and severally with JCC by certain subsidiaries of JCC (the "Subsidiary
Guarantors"). The JCC Debt Securities and JCC Convertible Debt Securities may be
fully and unconditionally guaranteed on a senior subordinated basis by Jacor and
may be further guaranteed fully and unconditionally, jointly and severally with
Jacor by the Subsidiary Guarantors (collectively with JCC and Jacor, the
"Guarantors"). The obligations of each Guarantor under its guarantee, however,
will be limited in a manner intended to avoid such guarantee being deemed a
fraudulent conveyance under applicable law. See "Fraudulent Transfer
Considerations" below.
 
    Reference is made to the Prospectus Supplement relating to the particular
Convertible Debt Securities or JCC Debt Securities offered thereby for the
following terms, where applicable, of the Convertible Debt Securities or JCC
Debt Securities: (i) the specific designation of the Convertible Debt Securities
or JCC Debt Securities; (ii) the denominations in which such Convertible Debt
Securities or JCC Debt Securities are authorized to be issued; (iii) the
aggregate principal amount of such Convertible Debt Securities or JCC Debt
Securities; (iv) the date or dates on which the principal of such Convertible
Debt Securities or JCC Debt Securities will mature or the method of determining
such date or dates; (v) the price or prices (expressed as a percentage of the
aggregate principal amount thereof) at which the Convertible Debt Securities or
JCC Debt Securities will be issued; (vi) the rate or rates (which may be fixed
or variable) at which such Convertible Debt Securities or JCC Debt Securities
will bear interest, if any, or the method of
 
                                       9
<PAGE>
calculating such rate or rates; (vii) the times and places where principal of,
premium, if any, and interest, if any, on such Convertible Debt Securities or
JCC Debt Securities will be payable; (viii) the date, if any, after which such
Convertible Debt Securities or JCC Debt Securities may be redeemed and the
redemption prices; (ix) the date or dates on which interest, if any, will be
payable and the record date or dates therefor or the method by which such date
or dates will be determined; (x) the period or periods within which, the price
or prices at which, the currency or currencies (including currency units) in
which, and the terms and conditions upon which, such Convertible Debt Securities
or JCC Debt Securities may be redeemed, in whole or in part, at the option of
Jacor or JCC, as applicable; (xi) the obligation, if any, of Jacor or JCC to
redeem or purchase such Convertible Debt Securities or JCC Debt Securities
pursuant to any sinking fund or analogous provisions, upon the happening of a
specified event or at the option of a holder thereof and the period or periods
within which, the price or prices at which and the terms and conditions upon
which, such Convertible Debt Securities or JCC Debt Securities shall be redeemed
or purchased, in whole or in part, pursuant to such obligations; (xii) the terms
and conditions upon which conversion or exchange of such Convertible Debt
Securities will be effected, including the exchange terms, the conversion price,
the conversion period and other conversion or exchange provisions in addition to
or in lieu of those described below; (xiii) if other than the principal amount
thereof, the portion of the principal amount of such Convertible Debt Securities
or JCC Debt Securities which will be payable upon declaration of the
acceleration of the maturity thereof or the method by which such portion shall
be determined; (xiv) the person to whom any interest on any such Debt Security
or Convertible Debt Security shall be payable if other than the person in whose
name such Debt Security or Convertible Debt Security is registered on the
applicable record date; (xv) any addition to, or modification or deletion of,
any Event of Default or any covenant of Jacor or JCC specified in the Indenture
with respect to such Convertible Debt Securities or JCC Debt Securities; (xvi)
the application, if any, of such means of defeasance or covenant defeasance as
may be specified for such Convertible Debt Securities or JCC Debt Securities;
(xvii) whether such Convertible Debt Securities or JCC Debt Securities are to be
issued in whole or in part in the form of one or more temporary or permanent
global securities and, if so, the identity of the depositary for such global
security or securities; (xviii) whether such Convertible Debt Securities or JCC
Debt Securities shall be subordinated and subject to the right to prior payment
in full of all Senior Debt, including the then-existing credit facilities; and
(xix) any other special terms pertaining to such Convertible Debt Securities or
JCC Debt Securities. Unless otherwise specified in the applicable Prospectus
Supplement, the Convertible Debt Securities or JCC Debt Securities will not be
listed on any securities exchange. Unless otherwise provided in the applicable
Prospectus Supplement, principal and premium, if any, or interest, if any, will
be payable and the Convertible Debt Securities or JCC Debt Securities may be
surrendered for payment or transferred at the offices of the applicable Trustee
as paying and authenticating agent, provided that payment of interest on
Registered Securities may be made at the option of Jacor or JCC, as applicable,
by check mailed to the address of the person entitled thereto as it appears in
the Security Register. Payment of Convertible Debt Securities or JCC Debt
Securities in bearer form will be made at such paying agencies outside of the
United States as Jacor or JCC, as applicable, may appoint.
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Convertible Debt Securities and JCC Debt Securities will be issued in fully
registered form without coupons in denominations set forth in the Prospectus
Supplement. No service charge will be made for any transfer or exchange of such
Convertible Debt Securities or JCC Debt Securities, but Jacor or JCC, as
applicable, may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. Where Convertible Debt
Securities and JCC Debt Securities of any series are issued in bearer form, the
special restrictions and considerations, including special offering restrictions
and special Federal income tax considerations, applicable to any such
Convertible Debt Securities or JCC Debt Securities and to payment on and
transfer and exchange of such Convertible Debt Securities or JCC Debt Securities
will be described in the Prospectus Supplement. Bearer Convertible Debt
Securities and JCC Debt Securities will be transferrable by delivery.
 
                                       10
<PAGE>
    Some of the Convertible Debt Securities and JCC Debt Securities may be
issued at a discount (bearing no interest or interest at below market rates) to
be sold at a substantial discount below their stated principal amount. Federal
income tax consequences and other special considerations applicable to any such
Convertible Debt Securities and JCC Debt Securities will be described in the
applicable Prospectus Supplement.
 
    The Prospectus Supplement for a particular series may indicate terms for
redemption at the option of a Holder. Unless otherwise indicated in the
applicable Prospectus Supplement, the covenants contained in the Indentures and
the Convertible Debt Securities or JCC Debt Securities (as the case may be)
would not provide for redemption at the option of a Holder nor necessarily
afford Holders thereof protection in the event of a highly leveraged or other
transaction that may adversely affect such Holders.
 
CONVERSION OF CONVERTIBLE DEBT SECURITIES
 
    The following provisions will further apply to Convertible Debt Securities,
unless otherwise provided in the applicable Prospectus Supplement for such
Convertible Debt Securities. The holder of any Convertible Debt Securities will
have the right exercisable at any time prior to maturity, or prior to such other
date as may be specified in the applicable Prospectus Supplement, unless
previously redeemed by Jacor or JCC, as applicable, to convert such Convertible
Debt Securities into shares of Jacor Common Stock or Jacor Preferred Stock at
the conversion price set forth in the applicable Prospectus Supplement, subject
to adjustment. In the case of Convertible Debt Securities called for redemption,
conversion rights will expire at the close of business on the date fixed for the
redemption unless Jacor or JCC, as applicable, shall default in payment of the
redemption price, except that in the case of redemption at the option of the
Holder thereof, if applicable, the conversion right will terminate upon receipt
of written notice of the exercise of such option. In certain events, the
conversion price will be subject to adjustment as set forth in the applicable
Prospectus Supplement. Fractional shares of Jacor Common Stock or Jacor
Preferred Stock will not be issued upon conversion, but, in lieu thereof, Jacor
or JCC, as applicable, will pay a cash adjustment based on the then current
market price for the Jacor Common Stock or Jacor Preferred Stock.
 
EXCHANGEABILITY
 
    The Holders of Convertible Debt Securities of any series may be obligated at
any time or at maturity to exchange them for Jacor Common Stock, Jacor Preferred
Stock or other debt securities of Jacor issued hereunder. The terms of any such
exchange will be described in the Prospectus Supplement relating to such series
of Convertible Debt Securities.
 
SUBORDINATION
 
    The Convertible Debt Securities and JCC Debt Securities may be subordinated
and junior in right of payment, to the extent set forth in the applicable
Prospectus Supplement, to all "Senior Debt" of Jacor, JCC or the Guarantors, as
applicable, including the then-existing credit facilities, as set forth in the
applicable Prospectus Supplement. Unless otherwise provided in the applicable
Indenture or applicable Prospectus Supplement, the subordination provisions of
the Indentures will be as set forth below.
 
    To the extent the JCC Debt Securities and/or the Convertible Debt Securities
are subordinated to Senior Debt, the Indentures will provide that no payment
(including any payment which may be payable to any Holder by reason of the
subordination of any other indebtedness or other obligations to, or guarantee
of, the Convertible Debt Securities and JCC Debt Securities) or distribution (by
set-off or otherwise) may be made by or on behalf of Jacor, JCC or a Guarantor,
as applicable, on account of the principal of, premium, if any, or interest on
the Convertible Debt Securities and JCC Debt Securities (including any
repurchases of Convertible Debt Securities and JCC Debt Securities) or any other
amounts with respect thereto, or on account of the redemption provisions of the
Convertible Debt Securities and JCC Debt Securities, for cash or property (other
than Junior Securities), (i) upon the maturity of any Senior Debt of Jacor, JCC
or such Guarantor by lapse of time, acceleration (unless waived) or otherwise,
unless and until all principal of, premium, if any, and the interest on, and all
other amounts with respect to, such Senior Debt are first paid in full in cash
or otherwise to the extent each of the holders of Senior Debt accept
satisfaction of amounts due to such holder by settlement in other than cash, or
(ii) in the event of default in the payment of any principal of, premium, if
any, or interest on, or any other amounts with respect to, Senior Debt of Jacor,
JCC or such
 
                                       11
<PAGE>
Guarantor when it becomes due and payable, whether at maturity or at a date
fixed for prepayment or by declaration or otherwise (each of the foregoing, a
"Payment Default"), unless and until such Payment Default has been cured or
waived or otherwise has ceased to exist.
 
    Upon (i) the happening of a default (other than a Payment Default) that
permits the holders of Senior Debt (or a percentage thereof) to declare such
Senior Debt to be due and payable and (ii) written notice of such default given
to Jacor, JCC or such Guarantor, as applicable, and the Trustee by
Representative under the then-existing credit facilities or the holders of an
aggregate of at least $25.0 million principal amount outstanding of any other
Senior Debt or their representative at such holders' direction (a "Payment
Notice"), then, unless and until such default has been cured or waived or
otherwise has ceased to exist, no payment (including any payment which may be
payable to any Holder by reason of the subordination of any other indebtedness
or other obligations to, or guarantee of, the Convertible Debt Securities and
JCC Debt Securities) or distribution (by set-off or otherwise) may be made by or
on behalf of Jacor, JCC or any Guarantor which is an obligor under such Senior
Debt on account of the principal of, premium, if any, or interest on the
Convertible Debt Securities and JCC Debt Securities (including any repurchases
of any of the Convertible Debt Securities and JCC Debt Securities), or any other
amount with respect thereto, or on account of the redemption provisions of the
Convertible Debt Securities and JCC Debt Securities, in any such case, other
than payments made with Junior Securities. Notwithstanding the foregoing, unless
the Senior Debt in respect of which such default exists has been declared due
and payable in its entirety within 179 days after the Payment Notice is
delivered as set forth above (the "Payment Blockage Period") (and such
declaration has not been rescinded or waived), at the end of the Payment
Blockage Period (and assuming that no Payment Default exists), Jacor, JCC and
the Guarantors, as applicable, shall not be prohibited by the subordination
provisions from paying all sums then due and not paid to the Holders of the
Convertible Debt Securities and JCC Debt Securities during the Payment Blockage
Period due to the foregoing prohibitions and to resume all other payments as and
when due on the Convertible Debt Securities and JCC Debt Securities. Any number
of Payment Notices may be given; PROVIDED, HOWEVER, that (i) not more than one
Payment Notice shall be given within a period of any 360 consecutive days, and
(ii) no default that existed upon the date of delivery of such Payment Notice
(whether or not such default is on the same issue of Senior Debt) shall be made
the basis for the commencement of any other Payment Blockage Period.
 
    Upon any distribution of assets of Jacor, JCC or any Guarantor upon any
dissolution, winding up, total or partial liquidation or reorganization of
Jacor, JCC or a Guarantor, whether voluntary or involuntary, in bankruptcy,
insolvency, receivership or a similar proceeding or upon assignment for the
benefit of creditors or any marshaling of assets or liabilities, (i) the holders
of all Senior Debt of Jacor, JCC or such Guarantor, as applicable, will first be
entitled to receive payment in full of all amounts of Senior Debt in cash or
otherwise to the extent each of such holders accepts satisfaction of amounts due
by settlement in other than cash before the Holders are entitled to receive any
payment (including any payment which may be payable to any Holder by reason of
the subordination of any other indebtedness or other obligations to, or
guarantee of, the Convertible Debt Securities and JCC Debt Securities) or
distribution on account of principal of, premium, if any, and interest on, or
any other amounts with respect to, the Convertible Debt Securities and JCC Debt
Securities (other than Junior Securities) and (ii) any payment or distribution
of assets of Jacor, JCC or such Guarantor of any kind or character from any
source, whether in cash, property or securities (other than Junior Securities)
to which the Holders or the Trustee on behalf of the Holders would be entitled
(by set-off or otherwise) except for the subordination provisions contained in
the Indentures, will be paid by the liquidating trustee or agent or other person
making such a payment or distribution directly to the holders of such Senior
Debt or their representative to the extent necessary to make payment in full on
all such Senior Debt remaining unpaid, after giving effect to any concurrent
payment or distribution to the holders of such Senior Debt.
 
    In the event that, notwithstanding the foregoing, any payment or
distribution of assets of Jacor, JCC or any Guarantor (other than Junior
Securities) shall be received by the Trustee or the Holders at a time when such
payment or distribution is prohibited by the foregoing provisions, such payment
or distribution shall be held in trust for the benefit of the holders of such
Senior Debt, and shall be paid or delivered by the Trustee or such Holders, as
the case may be, to the holders of such Senior Debt remaining unpaid or to their
 
                                       12
<PAGE>
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any of such Senior Debt
may have been issued, ratably according to the aggregate principal amounts
remaining unpaid on account of such Senior Debt held or represented by each, for
application to the payment of all such Senior Debt remaining unpaid, to the
extent necessary to pay all such Senior Debt in full in cash or otherwise to the
extent each of the holders of such Senior Debt accept satisfaction of amounts
due by settlement in other than cash after giving effect to any concurrent
payment or distribution to the holders of such Senior Debt. The Indentures will
contain other customary subordination provisions, including rights of
subrogation and rights to file claims in bankruptcy.
 
    As among Jacor, JCC, the Guarantors and the Holders, no provision contained
in the Indentures or the Convertible Debt Securities and JCC Debt Securities
will affect the obligations of Jacor, JCC and the Guarantors, which are absolute
and unconditional, to pay, when due, principal of, premium, if any, and interest
on the Convertible Debt Securities and JCC Debt Securities. The subordination
provisions of the Indentures and the Convertible Debt Securities and JCC Debt
Securities will not prevent the occurrence of any Default or Event of Default
under the Indentures or limit the rights of the Trustee or any Holder to pursue
any other rights or remedies with respect to the Convertible Debt Securities and
JCC Debt Securities.
 
    As a result of these subordination provisions, in the event of the
liquidation, bankruptcy, reorganization, insolvency, receivership or similar
proceeding or an assignment for the benefit of the creditors of Jacor, JCC or
any of the Guarantors or a marshaling of assets or liabilities of Jacor, JCC or
any of the Guarantors, holders of the Convertible Debt Securities and JCC Debt
Securities may receive ratably less than other creditors.
 
    Jacor and JCC conduct operations through their subsidiaries. Accordingly,
Jacor's and JCC's ability to meet their cash obligations will be dependent upon
the ability of their subsidiaries to make cash distributions to Jacor and JCC,
respectively. Furthermore, any right of Jacor or JCC to receive the assets of
any such subsidiary upon such subsidiary's liquidation or reorganization
effectively will be subordinated by operation of law to the claims of such
subsidiary's creditors (including trade creditors) and holders of such
subsidiary's preferred stock, except to the extent that Jacor or JCC, as
applicable, is itself recognized as a creditor or preferred stockholder of such
subsidiary, in which case the claims of Jacor or JCC, as applicable, would still
be subordinate to any indebtedness or preferred stock of such subsidiary senior
in right of payment to that held by Jacor or JCC, as applicable.
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
    Generally, under various state and federal fraudulent transfer or fraudulent
conveyance laws (collectively, "the Fraudulent Transfer Laws"), a Guarantor's
obligations under the Guarantee of the JCC Debt Securities and/or the
Convertible Debt Securities could be avoided if a court in a lawsuit by an
unpaid creditor of a Guarantor or a representative of such creditors (such as a
trustee in bankruptcy or JCC as debtor-in-possession) were to find that (i) the
Guarantor did not receive reasonably equivalent value or fair consideration in
exchange for the obligation created by the applicable Convertible Debt
Securities or JCC Debt Securities and (ii) at the time of the issuance of such
Convertible Debt Securities or JCC Debt Securities, the Guarantor (A) was
insolvent or became insolvent as a result of the incurrence of the obligations
represented by such Convertible Debt Securities or JCC Debt Securities, (B) was
engaged, or was about to be engaged, in a business or transaction for which the
property remaining with it was an unreasonably small capital or for which its
unencumbered assets constituted unreasonably small capital, or (C) intended to
incur, or believed that it would incur, debts beyond its ability to pay as such
debts matured.
 
    A court could conclude that a Guarantor did not receive reasonably
equivalent value or fair consideration to the extent that such Guarantor's
liability on its guarantee exceeds the economic benefits that it receives in the
offering of such Convertible Debt Securities or JCC Debt Securities. Were a
court to so find, the court could avoid the Guarantor's obligation under its
guarantee and direct the return of amounts paid thereunder if one or more of the
conditions set forth in subparagraphs (ii)(A), (B), or (C) above were also met
as to such Guarantor. Management believes, however, that the Guarantees will be
structured so as to minimize the likelihood that a court would find that the
Guarantor did not receive reasonably equivalent value or fair consideration for
its Guarantee (the "Savings Clause"). No assurance, however, can be given
 
                                       13
<PAGE>
that a court would uphold such a fraudulent transfer Savings Clause. Moreover,
there can be no assurance that a court would not limit a Guarantee to an amount
equal to the proceeds actually received by any given Guarantor from the offering
of such Convertible Debt Securities or JCC Debt Securities.
 
    The determination of insolvency for purposes of the Fraudulent Transfer Laws
may vary depending upon the law of the jurisdiction being applied. Generally,
however, an entity is insolvent if (i) the sum of its debts (including
unliquidated or contingent debts) is greater than all of its property, at a fair
valuation or (ii) the present fair saleable value of its assets is less than the
amount that will be required to pay its probable liability on its existing debts
as they become absolute and matured. Additionally, under certain state
Fraudulent Transfer Laws, an entity is presumed to be insolvent if it is
generally not paying its debts as they become due.
 
    Furthermore, a court could avoid Jacor's obligations under the Jacor
Convertible Debt Securities, JCC's obligations under the JCC Debt Securities
and/or JCC Convertible Debt Securities and the Guarantors' obligations under
their respective Guarantees without regard to the solvency, capitalization and
other conditions described in clauses (ii)(A), (B), and (C) above if it finds
that the obligations created by such Convertible Debt Securities or JCC Debt
Securities or the Guarantees were incurred with actual intent to hinder, delay,
or defraud now existing or future creditors. If the obligations under such
Convertible Debt Securities or JCC Debt Securities were to be avoided, there can
be no assurance that the recoveries under the Guarantees would be sufficient to
pay the outstanding amounts due and owing under such Convertible Debt Securities
or JCC Debt Securities. Moreover, if the obligations of one or more Guarantors
were to be avoided, there can be no assurance that the remaining Guarantees
would be sufficient to ensure payment in full on such Convertible Debt
Securities or JCC Debt Securities.
 
CERTAIN COVENANTS
 
    REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the covenants relating to repurchase upon a change of
control will be as set forth below. The Indentures will provide that in the
event that a Change of Control has occurred, each Holder of Convertible Debt
Securities or JCC Debt Securities will have the right, at such Holder's option,
pursuant to an irrevocable and unconditional offer by Jacor or JCC , as
applicable, (the "Change of Control Offer"), to require Jacor or JCC, as
applicable, to repurchase all or any part of such Holder's Convertible Debt
Securities or JCC Debt Securities (PROVIDED, that the principal amount of such
Convertible Debt Securities or JCC Debt Securities must be $1,000 or an integral
multiple thereof) on a date (the "Change of Control Purchase Date") that is no
later than 35 Business Days after the occurrence of such Change of Control, at a
cash price (the "Change of Control Purchase Price") equal to 101% of the
principal amount thereof, together with accrued and unpaid interest, if any, to
the Change of Control Purchase Date. The Change of Control Offer shall be made
within 10 Business Days following a Change of Control and shall remain open for
20 Business Days following its commencement (the "Change of Control Offer
Period"). Upon expiration of the Change of Control Offer Period, Jacor or JCC,
as applicable, promptly shall purchase all Convertible Debt Securities or JCC
Debt Securities properly tendered in response to the Change of Control Offer.
 
    As used herein, a "Change of Control" will mean (i) any merger or
consolidation of JCC with or into any person or any sale, transfer or other
conveyance, whether direct or indirect, of all or substantially all of any of
the assets of JCC, on a consolidated basis, in one transaction or a series of
related transactions, if, immediately after giving effect to such
transaction(s), any "person" or "group" (as such terms are used for purposes of
Sections 13(d) and 14(d) of the Exchange Act, whether or not applicable) (other
than an Excluded Person) is or becomes the "beneficial owner," directly or
indirectly, of more than 50% of the total voting power in the aggregate normally
entitled to vote in the election of directors, managers, or trustees, as
applicable, of the transferee(s) or surviving entity or entities, (ii) any
"person" or "group" (as such terms are used for purposes of Sections 13(d) and
14(d) of the Exchange Act, whether or not applicable) (other than an Excluded
Person) is or becomes the "beneficial owner," directly or indirectly, of more
than 50% of the total voting power in the aggregate of all classes of Capital
Stock of JCC then outstanding normally entitled to vote in elections of
directors, or (iii) during any period of 12 consecutive months after the Issue
Date,
 
                                       14
<PAGE>
individuals who at the beginning of any such 12-month period constituted the
Board of Directors of JCC (together with any new directors whose election by
such Board or whose nomination for election by the shareholders of JCC was
approved by a vote of a majority of the directors then still in office who were
either directors at the beginning of such period or whose election or nomination
for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors of JCC then in office.
 
    On or before the Change of Control Purchase Date, Jacor or JCC, as
applicable, will (i) accept for payment Convertible Debt Securities or JCC Debt
Securities or portions thereof properly tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent cash sufficient to pay the
Change of Control Purchase Price (together with accrued and unpaid interest) of
all Convertible Debt Securities or JCC Debt Securities so tendered and (iii)
deliver to the Trustee Convertible Debt Securities or JCC Debt Securities so
accepted together with an Officers' Certificate listing the Convertible Debt
Securities or JCC Debt Securities or portions thereof being purchased by Jacor
or JCC, as applicable. The Paying Agent promptly will pay the Holders of
Convertible Debt Securities or JCC Debt Securities so accepted an amount equal
to the Change of Control Purchase Price (together with accrued and unpaid
interest), and the Trustee promptly will authenticate and deliver to such
Holders a new Convertible Debt Security or JCC Debt Security equal in principal
amount to any unpurchased portion of the Convertible Debt Securities or JCC Debt
Securities surrendered. Any Convertible Debt Securities or JCC Debt Securities
not so accepted will be delivered promptly by Jacor or JCC, as applicable, to
the Holder thereof. Jacor or JCC, as applicable, publicly will announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Purchase Date.
 
    A change of control under the indenture which governs each of the
Convertible Debt Securities, JCC Debt Securities, 10 1/8% Notes (as defined
herein), LYONs due 2011 (as defined herein), 9 3/4% Notes (as defined herein)
and 8 3/4% Notes (as defined herein) will result in a default under the Credit
Facility (as defined herein). Additionally, unless Jacor and/or JCC, as
applicable, is successful in (i) seeking consents from its lenders under the
Credit Facility to permit change of control repurchase offers for each of the
Convertible Debt Securities, JCC Debt Securities, 10 1/8% Notes, LYONs due 2011,
9 3/4% Notes or 8 3/4% Notes, or (ii) refinancing such borrowings, such event of
default under the Credit Facility would constitute an event of default under
each of the Convertible Debt Securities, JCC Debt Securities, 10 1/8% Notes,
LYONs due 2011, 9 3/4% Notes and 8 3/4% Notes. Such events of default could
result in the immediate acceleration of all then outstanding indebtedness under
each of the Convertible Debt Securities, JCC Debt Securities, 10 1/8% Notes,
LYONs due 2011, 9 3/4% Notes and 8 3/4% Notes. As a result, differences in the
definitions of change of control under the indentures for the Convertible Debt
Securities, JCC Debt Securities, 10 1/8% Notes, LYONs due 2011, 9 3/4% Notes and
8 3/4% Notes will not have a difference in the effect on Jacor or JCC, as
applicable, or the respective holders other than where the lenders under the
Credit Facility have waived such event of default. In the event of such waiver
there could be a change of control under the Convertible Debt Securities, JCC
Debt Securities, 10 1/8% Notes, 9 3/4% Notes and 8 3/4% Notes which would not
result in a change of control under the LYONs due 2011 or VICE VERSA. See
"Description of Indebtedness."
 
    The Change of Control purchase feature of the Convertible Debt Securities or
JCC Debt Securities may make more difficult or discourage a takeover of Jacor or
JCC, and, thus, the removal of incumbent management.
 
    The phrase "all or substantially all" of the assets of Jacor or JCC, as
applicable, will likely be interpreted under applicable state law and will be
dependent upon particular facts and circumstances. As a result, there may be a
degree of uncertainty in ascertaining whether a sale or transfer of "all or
substantially all" of the assets of Jacor or JCC, as applicable, has occurred.
In addition, no assurance can be given that Jacor or JCC, as applicable, will be
able to acquire Convertible Debt Securities or JCC Debt Securities tendered upon
the occurrence of a Change of Control.
 
    Any Change of Control Offer will be made in compliance with all applicable
laws, rules and regulations, including, if applicable, Regulation 14E under the
Exchange Act and the rules thereunder and all other applicable Federal and state
securities laws.

    LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS AND DISQUALIFIED CAPITAL
STOCK
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the covenants relating to limitations on incurring
additional indebtedness and disqualified capital stock will be as set forth
below. the Indentures will provide that, except as set forth below in this
covenant, Jacor, JCC and any Subsidiary Guarantors will not, and will not permit
any of their Subsidiaries to, directly or indirectly, issue, assume, guaranty,
incur, become directly or indirectly liable with respect to (including as a
result of an Acquisition), or otherwise become responsible for, contingently or
otherwise (individually and collectively, to "incur" or, as appropriate, an
"incurrence"), any Indebtedness or any Disqualified Capital Stock (including
Acquired Indebtedness) other than Permitted Indebtedness. Notwithstanding the
foregoing limitations, Jacor or JCC may incur and the Subsidiary Guarantors may
guarantee Indebtedness and Disqualified Capital Stock in addition to Permitted
Indebtedness: if (i) no Default or Event of Default shall have occurred and be
continuing at the time of, or would occur after giving effect on a PRO FORMA
basis to, such incurrence of Indebtedness or Disqualified Capital Stock and (ii)
on the date of such incurrence (the "Incurrence Date"), the Leverage Ratio of
JCC for the Reference Period immediately preceding the Incurrence Date, after
giving effect on a pro forma basis to such incurrence of such Indebtedness or
Disqualified Capital Stock and, to the extent set forth in the definition of
Leverage Ratio, the use of proceeds thereof, would be less than the ratio
specified in the Indentures.
 
    Indebtedness or Disqualified Capital Stock of any person which is
outstanding at the time such person becomes a Subsidiary of Jacor or JCC
(including upon designation of any subsidiary or other person as a Subsidiary)
or is merged with or into or consolidated with Jacor or JCC or a Subsidiary of
Jacor or JCC, respectively, shall be deemed to have been incurred at the time
such Person becomes such a Subsidiary of Jacor or JCC, respectively, or is
merged with or into or consolidated with Jacor or JCC, respectively, or a
Subsidiary of Jacor or JCC, as applicable.
 
    LIMITATION ON RESTRICTED PAYMENTS
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that Jacor and JCC and their
Subsidiaries will not, and will not permit any of their Subsidiaries to,
directly or indirectly, make any Restricted Payment if, after giving effect to
such Restricted Payment on a PRO FORMA basis, (1) a Default or an Event of
Default shall have occurred and be continuing, (2) Jacor and JCC is not
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Leverage Ratio described in the covenant "Limitation on Incurrence of Additional
Indebtedness and Disqualified Capital Stock," or (3) the aggregate amount of all
Restricted Payments made by Jacor and JCC and their Subsidiaries, including
after giving effect to such proposed Restricted Payment, from and after the
Issue Date, would exceed the amount specified in the Indentures.
 
    The foregoing clauses (2) and (3) of the immediately preceding paragraph,
however, will not prohibit (w) payments to Jacor to reimburse Jacor for
reasonable and necessary corporate and administrative expenses, (x) Restricted
Investments, provided, that, after giving pro forma effect to such Restricted
Investment, the aggregate amount of all such Restricted Investments made on or
after the Issue Date that are outstanding (after giving effect to any such
Restricted Investments that are returned to JCC or the Subsidiary Guarantor that
made such prior Restricted Investment, without restriction, in cash on or prior
to the date of any such calculation) at any time does not exceed an amount
specified in the Indentures, (y) a Qualified Exchange, and (z) the payment of
any dividend on Qualified Capital Stock within 60 days after the date of its
declaration if such dividend could have been made on the date of such
declaration in compliance with the foregoing provisions.
 
    LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING
SUBSIDIARIES
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that Jacor, JCC and their
Subsidiaries will not, and will not permit any of their Subsidiaries to, create,
assume or suffer to exist any consensual restriction on the ability of any
Subsidiary of Jacor or JCC to pay dividends or make other distributions to or on
behalf of, or to pay any obligation to or on behalf of, or otherwise to transfer
assets or property to or on behalf of, or make or pay loans or advances to
 
                                       16
<PAGE>
or on behalf of, Jacor or JCC or any Subsidiary of Jacor or JCC, respectively,
except (a) restrictions imposed by the JCC Debt Securities, the Convertible Debt
Securities or the Indenture, (b) restrictions imposed by applicable law, (c)
existing restrictions under specified Indebtedness outstanding on the Issue
Date, (d) restrictions under any Acquired Indebtedness not incurred in violation
of the Indentures or any agreement relating to any property, asset, or business
acquired by Jacor, JCC or any of their Subsidiaries, which restrictions in each
case existed at the time of acquisition, were not put in place in connection
with or in anticipation of such acquisition and are not applicable to any
person, other than the person acquired, or to any property, asset or business,
other than the property, assets and business so acquired, (e) any such
restriction or requirement imposed by Indebtedness incurred under paragraph (f)
under the definition of Permitted Indebtedness, provided such restriction or
requirement is no more restrictive than that imposed by Jacor's or JCC's, as
applicable, credit facilities in effect as of the Issue Date, (f) restrictions
with respect solely to a Subsidiary of Jacor or JCC imposed pursuant to a
binding agreement which has been entered into for the sale or disposition of all
or substantially all of the Equity Interests or assets of such Subsidiary,
provided such restrictions apply solely to the Equity Interests or assets of
such Subsidiary which are being sold, and (g) in connection with and pursuant to
permitted Refinancings, replacements of restrictions imposed pursuant to clauses
(a), (c) or (d) of this paragraph that are not more restrictive than those being
replaced and do not apply to any other person or assets than those that would
have been covered by the restrictions in the Indebtedness so refinanced.
Notwithstanding the foregoing, neither (a) customary provisions restricting
subletting or assignment of any lease entered into in the ordinary course of
business, consistent with industry practice, or other standard non-assignment
clauses in contracts entered into in the ordinary course of business, (b)
Capital Leases or agreements governing purchase money Indebtedness which contain
restrictions of the type referred to above with respect to the property covered
thereby, nor (c) Liens permitted under the terms of the Indenture on assets
securing Senior Debt incurred pursuant to the Leverage Ratio in accordance with
the covenant described under "Limitation on Incurrence of Additional
Indebtedness and Disqualified Capital Stock" or permitted pursuant to the
definition of Permitted Indebtedness shall in and of themselves be considered a
restriction on the ability of the applicable Subsidiary to transfer such
agreement or assets, as the case may be.
 
    LIMITATIONS ON LAYERING INDEBTEDNESS; LIENS
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that Jacor, JCC and their
Subsidiaries will not, and will not permit any of their Subsidiaries to,
directly or indirectly, incur, or, other than with respect to the 10 1/8% Notes,
9 3/4% Notes and 8 3/4% Notes suffer to exist (a) any Indebtedness that is
subordinate in right of payment to any other Indebtedness of Jacor, JCC or a
Guarantor unless, by its terms, such Indebtedness (i) has a maturity date
subsequent to the Stated Maturity of the respective Convertible Debt Securities
or JCC Debt Securities and an Average Life longer than that of such Convertible
Debt Securities or JCC Debt Securities and (ii) is subordinate in right of
payment to, or ranks PARI PASSU with, such JCC Debt Securities, Convertible Debt
Securities or the Guarantees, as applicable, or (b) other than Permitted Liens,
any Lien upon any of its property or assets, whether now owned or hereafter
acquired, or upon any income or profits therefrom securing Indebtedness other
than (1) Liens securing Senior Debt incurred pursuant to the Leverage Ratio in
accordance with the covenant described under "Limitation on Incurrence of
Additional Indebtedness and Disqualified Capital Stock" and (2) Liens securing
Senior Debt incurred as permitted pursuant to the definition of Permitted
Indebtedness.
 
    LIMITATION ON SALE OF ASSETS AND SUBSIDIARY STOCK
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the covenants relating to limitations on sales of assets
and Subsidiary stock will be as set forth below. The Indentures will provide
that Jacor, JCC and their Subsidiaries will not, and will not permit any of
their Subsidiaries to, in one or a series of related transactions, sell,
transfer, or otherwise dispose of, any of its property, business or assets,
including by merger or consolidation (in the case of a Guarantor or a Subsidiary
of Jacor or JCC), and including any sale or other transfer or issuance of any
Equity Interests of any direct or indirect Subsidiary of Jacor or JCC, whether
by Jacor or JCC or a direct or indirect Subsidiary thereof (an

Net Cash Proceeds therefrom (the "Asset Sale Offer Amount") are (a) applied to
the optional redemption of the Convertible Debt Securities and/or JCC Debt
Securities in accordance with the terms of the Indentures or to the repurchase
of the Convertible Debt Securities and/or JCC Debt Securities pursuant to an
irrevocable, unconditional cash offer (the "Asset Sale Offer") to repurchase
Convertible Debt Securities and/or JCC Debt Securities at a purchase price (the
"Asset Sale Offer Price") of 100% of principal amount, plus accrued interest to
the date of payment, (b) invested in assets and property (other than notes,
bonds, obligations and securities) which in the good faith reasonable judgment
of the Board of Jacor or JCC, as applicable, will immediately constitute or be a
part of a Related Business of Jacor or JCC, as applicable, or a Subsidiary (if
it continues to be a Subsidiary) immediately following such transaction or (c)
used to permanently retire or reduce Senior Debt or Indebtedness permitted
pursuant to paragraphs (d), (e) or (f) under the definition of Permitted
Indebtedness (including that in the case of a revolver or similar arrangement
that makes credit available, such commitment is so permanently reduced by such
amount), (2) with respect to any Asset Sale or related series of Asset Sales
involving securities, property or assets with an aggregate fair market value in
excess of $2.5 million, at least 75% of the consideration for such Asset Sale or
series of related Asset Sales (excluding the amount of (A) any Indebtedness
(other than the Convertible Debt Securities and/or JCC Debt Securities) that is
required to be repaid or assumed (and is either repaid or assumed by the
transferee of the related assets) by virtue of such Asset Sale and which is
secured by a Lien on the property or asset sold and (B) property received by
Jacor or JCC, as applicable, or any such Subsidiary from the transferee that
within 90 days of such Asset Sale is converted into cash or Cash Equivalents)
consists of cash or Cash Equivalents (other than in the case of an Asset Swap or
where Jacor or JCC, as applicable, is exchanging all or substantially all the
assets of one or more Related Businesses operated by Jacor or JCC, as
applicable, or its Subsidiaries (including by way of the transfer of capital
stock) for all or substantially all the assets (including by way of the transfer
of capital stock) constituting one or more Related Businesses operated by
another person, in which event the foregoing requirement with respect to the
receipt of cash or Cash Equivalents shall not apply), (3) no Default or Event of
Default shall have occurred and be continuing at the time of, or would occur
after giving effect, on a PRO FORMA basis, to, such Asset Sale, and (4) the
Board of Jacor or JCC, as applicable, determines in good faith that Jacor or
JCC, as applicable, or such Subsidiary, as applicable, receives fair market
value for such Asset Sale.
 
    The Indentures will provide that an Asset Sale Offer may be deferred until
the accumulated Net Cash Proceeds from Asset Sales not applied to the uses set
forth in (1)(b) or (1)(c) above (the "Excess Proceeds") exceeds $5.0 million and
that each Asset Sale Offer shall remain open for 20 Business Days following its
commencement and no longer (the "Asset Sale Offer Period"). Upon expiration of
the Asset Sale Offer Period, Jacor or JCC, as applicable, shall apply the Asset
Sale Offer Amount plus an amount equal to accrued interest to the purchase of
all Convertible Debt Securities and/or JCC Debt Securities properly tendered (on
a PRO RATA basis if the Asset Sale Offer Amount is insufficient to purchase all
Convertible Debt Securities and/or JCC Debt Securities so tendered) at the Asset
Sale Offer Price (together with accrued interest). To the extent that the
aggregate amount of Convertible Debt Securities and/or JCC Debt Securities
tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer
Amount, Jacor or JCC, as applicable, may use any remaining Net Cash Proceeds for
general corporate purposes as otherwise permitted by the Indentures and
following each Asset Sale Offer the Excess Proceeds amount shall be reset to
zero. If required by applicable law, the Asset Sale Offer Period may be extended
as so required, however, if so extended it shall nevertheless constitute an
Event of Default if within 60 Business Days of its commencement the Asset Sale
Offer is not consummated or the properly tendered Convertible Debt Securities
and/or JCC Debt Securities are not purchased pursuant thereto.
 
    Notwithstanding the foregoing provisions of the first paragraph of this
covenant the Indentures will provide that with respect to an Asset Sale Offer,
Jacor or JCC, as applicable, will not be permitted to commence an Asset Sale
Offer for the Convertible Debt Securities and/or JCC Debt Securities until such
time as an Asset Sale Offer for the 10 1/8% Notes, 9 3/4% Notes and 8 3/4% Notes
in each case if required, has been completed. To the extent that any Excess
Proceeds remain after expiration of an Asset Sale Offer Period for the 10 1/8%
Notes, 9 3/4% Notes and 8 3/4% Notes, Jacor or JCC, as applicable, may use the
remaining
 
                                       18
<PAGE>
Net Cash Proceeds to commence an Asset Sale Offer for the Convertible Debt
Securities and/or JCC Debt Securities; PROVIDED, that with respect to the
10 1/8% Notes, 9 3/4% Notes and 8 3/4% Notes this paragraph shall be of no
further force and effect upon the earlier of (w) the maturity of the 10 1/8%
Notes, 9 3/4% Notes or 8 3/4% Notes, as applicable, (x) the date upon which
defeasance of the 10 1/8% Notes, 9 3/4% Notes or 8 3/4% Notes, as applicable,
becomes effective, (y) the date on which there are no longer any 10 1/8% Notes,
9 3/4% Notes or 8 3/4% Notes, as applicable, outstanding under the terms of the
governing indenture and (z) the date on which the Limitation on Sale of Assets
and Subsidiary Stock covenant no longer applies in accordance with the terms of
the indenture governing the 10 1/8% Notes, 9 3/4% Notes or 8 3/4% Notes, as
applicable.
 
    Notwithstanding the foregoing provisions of the first paragraph of this
covenant and without complying with the foregoing provisions:
 
        (i) Jacor or JCC, as applicable, and its Subsidiaries may convey, sell,
    transfer, assign or otherwise dispose of assets pursuant to and in
    accordance with the limitation on mergers, sales or consolidations
    provisions in the Indentures;
 
        (ii) Jacor or JCC, as applicable, and its Subsidiaries may sell or
    dispose of inventory or damaged, worn out or other obsolete property in the
    ordinary course of business so long as such property is no longer necessary
    for the proper conduct of the business of Jacor or JCC, as applicable, or
    such Subsidiary, as applicable; and
 
       (iii) any of Jacor's or JCC's, as applicable, Subsidiaries may convey,
    sell, transfer, assign or otherwise dispose of assets to, or merge with or
    into, Jacor or JCC, as applicable, or any of its wholly owned Subsidiary
    Guarantors.
 
    All Net Cash Proceeds from an Event of Loss shall be applied to the
restoration, repair or replacement of the asset so affected or invested, used
for prepayment of Senior Debt, or used to repurchase Convertible Debt Securities
and/or JCC Debt Securities, all within the period and as otherwise provided
above in clauses 1(a), 1(b) or 1(c) of the first paragraph of this covenant.
 
    In addition to the foregoing, Jacor or JCC, as applicable, will not, and
will not permit any of its Subsidiaries to, directly or indirectly make any
Asset Sale of any of the Equity Interests of any Subsidiary except pursuant to
an Asset Sale of all the Equity Interests of such Subsidiary.
 
    Any Asset Sale Offer shall be made in compliance with all applicable laws,
rules, and regulations, including, if applicable, Regulation 14E of the Exchange
Act and the rules and regulations thereunder and all other applicable Federal
and state securities laws.
 
    LIMITATION ON ASSET SWAPS
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that Jacor, JCC and their
Subsidiaries will not, and will not permit any of their Subsidiaries to, in one
or a series of related transactions, directly or indirectly, engage in any Asset
Swaps, unless: (i) at the time of entering into the agreement to swap assets and
immediately after giving effect to the proposed Asset Swap, no Default or Event
of Default shall have occurred and be continuing or would occur as a consequence
thereof; (ii) Jacor or JCC would, after giving PRO FORMA effect to the proposed
Asset Swap, have been permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Leverage Ratio in the covenant "Limitation on
Incurrence of Additional Indebtedness and Disqualified Capital Stock;" (iii) the
respective fair market values of the assets being purchased and sold by Jacor,
JCC or any of their Subsidiaries (as determined in good faith by the management
of Jacor or JCC or, if such Asset Swap includes consideration in excess of $2.5
million, by the Board of Directors of Jacor or JCC, respectively, as evidenced
by a Board Resolution) are substantially the same at the time of entering into
the agreement to swap assets; and (iv) at the time of the consummation of the
proposed Asset Swap, the percentage of any decline in the fair market value
(determined as aforesaid) of the asset or assets being acquired by Jacor, JCC
and their Subsidiaries shall not be significantly greater than the percentage of
any decline in the fair market value (determined as aforesaid) of the assets
being disposed of by Jacor, JCC or their Subsidiaries, calculated from the time
the agreement to swap assets was entered into.
 
                                       19

    LIMITATION ON TRANSACTIONS WITH AFFILIATES
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that neither Jacor, JCC nor
any of their Subsidiaries will be permitted after the Issue Date to enter into
any contract, agreement, arrangement or transaction with any Affiliate (an
"Affiliate Transaction"), or any series of related Affiliate Transactions (other
than Exempted Affiliate Transactions), (i) unless it is determined that the
terms of such Affiliate Transaction are fair and reasonable to Jacor or JCC, as
applicable, and no less favorable to Jacor or JCC, as applicable, than could
have been obtained in an arm's length transaction with a non-Affiliate and, (ii)
if involving consideration to either party in excess of $5.0 million, unless
such Affiliate Transaction(s) is evidenced by (A) an Officers' Certificate
addressed and delivered to the Trustee certifying that such Affiliate
Transaction(s) has been approved by a majority of the members of the Board of
Directors of Jacor or JCC, as applicable, who are disinterested in such
transaction or, (B) with regard to JCC, in the event there are no members of the
Board of Directors of JCC who are disinterested in such transaction, then so
long as JCC is a wholly owned subsidiary of Jacor, an Officers' Certificate
addressed and delivered to the Trustee certifying that such Affiliate
Transaction(s) have been approved by a majority of the members of the Board of
Directors of Jacor who are disinterested in such transaction and (iii) if
involving consideration to either party in excess of $10.0 million, unless in
addition Jacor or JCC, as applicable, prior to the consummation thereof, obtains
a written favorable opinion as to the fairness of such transaction to Jacor or
JCC, as applicable, from a financial point of view from an independent
investment banking firm of national reputation.
 
    LIMITATION ON MERGER, SALE OR CONSOLIDATION
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the covenants on mergers, sales and consolidation will be
as set forth below. The Indentures will provide that Jacor and JCC will not,
directly or indirectly, consolidate with or merge with or into another person or
sell, lease, convey or transfer all or substantially all of their assets
(computed on a consolidated basis), whether in a single transaction or a series
of related transactions, to another person or group of affiliated persons or
adopt a Plan of Liquidation, unless (i) either (a) Jacor or JCC, as applicable,
is the continuing entity or (b) the resulting, surviving or transferee entity
or, in the case of a Plan of Liquidation, the entity which receives the greatest
value from such Plan of Liquidation is a corporation organized under the laws of
the United States, any state thereof or the District of Columbia and expressly
assumes by supplemental indenture all of the obligations of Jacor or JCC, as
applicable, in connection with the JCC Debt Securities, Convertible Debt
Securities and/or the Indentures; (ii) no Default or Event of Default shall
exist or shall occur immediately after giving effect on a PRO FORMA basis to
such transaction; and (iii) immediately after giving effect to such transaction
on a PRO FORMA basis, the consolidated resulting, surviving or transferee entity
or, in the case of a Plan of Liquidation, the entity which receives the greatest
value from such Plan of Liquidation would immediately thereafter be permitted to
incur at least $1.00 of additional Indebtedness pursuant to the Leverage Ratio
set forth in the covenant described under "Limitation on Incurrence of
Additional Indebtedness and Disqualified Capital Stock."
 
    Upon any consolidation or merger or any transfer of all or substantially all
of the assets of Jacor or JCC or consummation of a Plan of Liquidation in
accordance with the foregoing, the successor corporation formed by such
consolidation or into which Jacor or JCC, as applicable, is merged or to which
such transfer is made or, in the case of a Plan of Liquidation, the entity which
receives the greatest value from such Plan of Liquidation shall succeed to, and
be substituted for, and may exercise every right and power of, Jacor or JCC
under the Indentures with the same effect as if such successor corporation had
been named therein as Jacor or JCC, and Jacor or JCC shall be released from the
obligations under the respective Convertible Debt Securities and/or JCC Debt
Securities and the Indentures except with respect to any obligations that arise
from, or are related to, such transaction.
 
    For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise) of all or substantially all of the properties and assets of one or
more Subsidiaries, Jacor's or JCC's interest in which constitutes all or
substantially all of the properties and assets of Jacor or JCC, as applicable,
shall be deemed to be the transfer of all or substantially all of the properties
and assets of Jacor or JCC, as applicable.

<PAGE>
    LIMITATION ON LINES OF BUSINESS
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that neither Jacor, JCC nor

extent in any line or lines of business activity other than that which is a
Related Business.
 
    RESTRICTION ON SALE AND ISSUANCE OF SUBSIDIARY STOCK
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that Jacor, JCC and the

to any person other than Jacor or JCC, as applicable, or a wholly owned
Subsidiary of Jacor or JCC, as applicable, except for Equity Interests with no
preferences or special rights or privileges and with no redemption or prepayment

future Subsidiaries of Jacor or JCC and their Subsidiaries, which are not
prohibited from becoming guarantors by law or by the terms of any Acquired
Indebtedness or any agreement (other than an agreement entered into in
connection with the transaction resulting in such person becoming a Subsidiary
of Jacor, JCC or their Subsidiaries) to which such Subsidiary is a party,
jointly and severally, will guaranty fully and unconditionally all principal,
premium, if any, and interest on the JCC Debt Securities and the Convertible
Debt Securities on a senior subordinated basis; PROVIDED, HOWEVER, that upon any
change in the law, Acquired Indebtedness or any agreement (whether by
expiration, termination or otherwise) which no longer prohibits a Subsidiary of
Jacor or JCC from becoming a Subsidiary Guarantor, such Subsidiary shall
immediately thereafter become a Subsidiary Guarantor; PROVIDED, FURTHER, in the
event that any Subsidiary of Jacor, JCC or their Subsidiaries becomes a
guarantor of any other Indebtedness of Jacor, JCC or any of their Subsidiaries
or any of their Subsidiaries, such Subsidiary shall immediately thereafter
become a Subsidiary Guarantor.
 
    All subsidiaries of Jacor or JCC, as applicable, will be Subsidiary
Guarantors if required by the covenant "Subsidiary Guarantors."
 
    RELEASE OF GUARANTORS
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will provide that no Guarantor shall
consolidate or merge with or into (whether or not such Guarantor is the
surviving Person) another Person unless (i) subject to the provisions of the
following paragraph and certain other provisions of the Indentures, the Person
formed by or surviving any such consolidation or merger (if other than such
Guarantor) assumes all the obligations of such Guarantor pursuant to a
supplemental indenture in form reasonably satisfactory to the Trustee, pursuant
to which such Person shall unconditionally guarantee, on a senior subordinated
basis, all of such Guarantor's obligations under such Guarantor's guarantee, the
Indentures on the terms set forth in the Indentures; (ii) immediately before and
immediately after giving effect to such transaction on a PRO FORMA basis, no

business.

<PAGE>
    Upon the sale or disposition (whether by merger, stock purchase, asset sale
or otherwise) of a Subsidiary Guarantor or all of its assets to an entity which
is not a Subsidiary Guarantor, which transaction is otherwise in compliance with
the Indentures, such Subsidiary Guarantor will be deemed released from its
obligations under its Guarantee of the Convertible Debt Securities and/or JCC
Debt Securities; PROVIDED, HOWEVER, that any such termination shall occur only
to the extent that all obligations of such Subsidiary Guarantor under all of its
guarantees of, and under all of its pledges of assets or other security
interests which secure, any Indebtedness of Jacor or JCC or any other Subsidiary
shall also terminate upon such release, sale or transfer.
 
    LIMITATION ON STATUS AS INVESTMENT COMPANY
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the Indentures will prohibit Jacor, JCC and their
Subsidiaries from being required to register as an "investment company" (as that
term is defined in the Investment Company Act of 1940, as amended), or from
otherwise becoming subject to regulation under the Investment Company Act.
 
REPORTS
 
    The JCC Indenture will provide that for so long as Jacor or any successor
thereto is subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act and JCC is a wholly owned subsidiary of Jacor, JCC shall deliver to
the Trustee and, to each Holder, Jacor's annual and quarterly reports pursuant
to Section 13 or 15(d) of the Exchange Act, within 15 days after such reports
have been filed with the Commission; PROVIDED, HOWEVER, in the event either (i)
Jacor or a successor as set forth above is no longer subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act or (ii) JCC is no longer
a wholly owned subsidiary of Jacor or a successor as set forth above, the JCC
Indenture will provide that whether or not JCC is subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, JCC shall deliver to
the Trustee and, to each Holder, within 15 days after it is or would have been
(if it were subject to such reporting obligations) required to file such with
the Commission, annual and quarterly financial statements substantially
equivalent to financial statements that would have been included in reports
filed with the Commission, if JCC were subject to the requirements of Section 13
or 15(d) of the Exchange Act, including, with respect to annual information
only, a report thereon by JCC's certified independent public accountants as such
would be required in such reports to the Commission, and, in each case, together
with a management's discussion and analysis of financial condition and results
of operations which would be so required and, to the extent permitted by the
Exchange Act or the Commission (if it were subject to such reporting

EVENTS OF DEFAULT AND REMEDIES
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the events of default and remedies will be as set forth
below. The Indentures will define an Event of Default as (i) the failure by
Jacor or JCC, as applicable, to pay any installment of interest on the
Convertible Debt Securities and/or JCC Debt Securities as and when the same
becomes due and payable and the continuance of any such failure for 30 days,
(ii) the failure by Jacor or JCC, as applicable, to pay all or any part of the
principal, or premium, if any, on such Convertible Debt Securities or JCC Debt
Securities when and as the same becomes due and payable at maturity, redemption,
by acceleration or otherwise, (iii) the failure by Jacor, JCC or any Guarantor,
as applicable, to observe or perform any other covenant or agreement contained
in the JCC Debt Securities, Convertible Debt Securities and/or the Indentures
and, subject to certain exceptions, the continuance of such failure for a period
of 60 days after written notice is given to Jacor or JCC, as applicable, by the
Trustee or to Jacor or JCC, as applicable, and the Trustee by the Holders of at
least 25% in aggregate principal amount of the such Convertible Debt Securities
or JCC Debt Securities outstanding, as the case may be, (iv) certain events of
bankruptcy, insolvency or reorganization in respect of Jacor, JCC or any of
their Significant Subsidiaries, (v) a default in any issue of Indebtedness of
Jacor, JCC or any of their Subsidiaries with an aggregate principal amount in
excess of $5.0 million (a) resulting from the failure to pay principal at final
maturity or (b) as a result of which the maturity of such Indebtedness has been
accelerated prior to its stated maturity, and (vi) final unsatisfied judgments
not covered by insurance aggregating in
 
                                       22
<PAGE>
excess of $5.0 million, at any one time rendered against Jacor, JCC or any of
their Subsidiaries and not stayed, bonded or discharged within 60 days. The
Indentures will provide that if a Default occurs and is continuing, the Trustee
must, within 90 days after the occurrence of such Default, give to the Holders
notice of such Default.
 
    If an Event of Default occurs and is continuing (other than an Event of
Default specified in clause (iv) above relating to Jacor, JCC or any Significant
Subsidiary,) then in every such case, unless the principal of all of the
Convertible Debt Securities and JCC Debt Securities shall have already become
due and payable, either the Trustee or the Holders of 25% in aggregate principal
amount of such Convertible Debt Securities or JCC Debt Securities at the time
outstanding, by notice in writing to Jacor or JCC (and to the Trustee if given
by Holders) (an "Acceleration Notice"), may declare all principal, determined as
set forth below, and accrued interest thereon to be due and payable immediately;
PROVIDED, HOWEVER, that if any Senior Debt is outstanding pursuant to Jacor's or
JCC's credit facilities then in effect upon a declaration of such acceleration,
such principal and interest shall be due and payable upon the earlier of (x) the
third Business Day after the sending to Jacor or JCC, as applicable, and the
Representative of such written notice, unless such Event of Default is cured or
waived prior to such date and (y) the date of acceleration of any Senior Debt
under such credit facilities. In the event a declaration of acceleration
resulting from an Event of Default described in clause (v) above has occurred
and is continuing, such declaration of acceleration shall be automatically
annulled if such default is cured or waived or the holders of the Indebtedness
which is the subject of such default have rescinded their declaration of
acceleration in respect of such Indebtedness within five days thereof and the
Trustee has received written notice or such cure, waiver or rescission and no
other Event of Default described in clause (v) above has occurred that has not
been cured or waived within five days of the declaration of such acceleration in
respect of such Indebtedness. If an Event of Default specified in clause (iv),
above, relating to Jacor, JCC or any Significant Subsidiary occurs, all
principal and accrued interest thereon will be immediately due and payable on
all outstanding Convertible Debt Securities and JCC Debt Securities without any
declaration or other act on the part of Trustee or the Holders. The Holders of a
majority in aggregate principal amount of such Convertible Debt Securities or
JCC Debt Securities at the time outstanding, as the case may be, generally are
authorized to rescind such acceleration if all existing Events of Default, other
than the non-payment of the principal of, premium, if any, and interest on such
Convertible Debt Securities or JCC Debt Securities which have become due solely
by such acceleration and except on default with respect to any provision
requiring a supermajority approval to amend, which default may only be waived by
such a supermajority, and have been cured or waived.
 
    Prior to the declaration of acceleration of the maturity of any Convertible
Debt Securities or JCC Debt Securities, the Holders of a majority in aggregate
principal amount of such Convertible Debt Securities or JCC Debt Securities at
the time outstanding, as the case may be, may waive on behalf of all the Holders
any default, except on default with respect to any provision requiring a
supermajority approval to amend, which default may only be waived by such a
supermajority, and except a default in the payment of principal of or interest
on any Debt Security or Convertible Debt Security not yet cured or a default
with respect to any covenant or provision which cannot be modified or amended
without the consent of the Holder of each outstanding Debt Security or
Convertible Debt Security affected. Subject to the provisions of the Indentures
relating to the duties of the Trustee, the Trustee will be under no obligation
to exercise any of its rights or powers under the Indentures at the request,
order or direction of any of the Holders, unless such Holders have offered to
the Trustee reasonable security or indemnity. Subject to all provisions of the
Indentures and applicable law, the Holders of a majority in aggregate principal
amount of the Convertible Debt Securities or JCC Debt Securities at the time
outstanding, as the case may be, will have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    Unless otherwise provided in the applicable Indenture or applicable
Prospectus Supplement, the procedures for legal defeasance and covenant
defeasance will be as set forth below. The Indentures will provide that Jacor or
JCC may, at its option, elect to have its obligations and the obligations of the
 
                                       23
<PAGE>
Guarantors discharged with respect to the outstanding Convertible Debt
Securities and/or JCC Debt Securities ("Legal Defeasance"). Such Legal
Defeasance means that Jacor or JCC, as applicable, shall be deemed to have paid
and discharged the entire indebtedness represented, and the Indentures shall
cease to be of further effect as to all such outstanding Convertible Debt
Securities and JCC Debt Securities and Guarantees, except as to (i) rights of
Holders to receive payments in respect of the principal of, premium, if any, and
interest on such Convertible Debt Securities and JCC Debt Securities when such
payments are due from the trust funds; (ii) Jacor's or JCC's, as applicable,
obligations with respect to such Convertible Debt Securities and JCC Debt
Securities concerning issuing temporary Convertible Debt Securities and JCC Debt
Securities, registration of Convertible Debt Securities and JCC Debt Securities,
mutilated, destroyed, lost or stolen Convertible Debt Securities and JCC Debt
Securities, and the maintenance of an office or agency for payment and money for
security payments held in trust; (iii) the rights, powers, trust, duties, and
immunities of the Trustee, and Jacor's or JCC's, as applicable, obligations in
connection therewith; and (iv) the Legal Defeasance provisions of the
Indentures. In addition, Jacor or JCC may, at its option and at any time, elect
to have the obligations of Jacor or JCC and the Guarantors released with respect
to certain covenants that are described in the Indentures ("Covenant
Defeasance") and thereafter any omission to comply with such obligations shall
not constitute a Default or Event of Default with respect to the Convertible
Debt Securities and JCC Debt Securities. In the event Covenant Defeasance
occurs, certain events (not including non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Convertible Debt
Securities and JCC Debt Securities.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
Jacor or JCC, as applicable, must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders of the Convertible Debt Securities and JCC
Debt Securities, U.S. legal tender, U.S. Government Obligations or a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants, to pay the principal of,
premium, if any, and interest on such Convertible Debt Securities and JCC Debt
Securities on the stated date for payment thereof or on the redemption date of
such principal or installment of principal of, premium, if any, or interest on
such Convertible Debt Securities and JCC Debt Securities, and the Holders of
Convertible Debt Securities and JCC Debt Securities must have a valid,
perfected, exclusive security interest in such trust; (ii) in the case of the
Legal Defeasance, Jacor or JCC, as applicable, shall have delivered to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that (A) Jacor or JCC, as applicable, has received from, or
there has been published by the Internal Revenue Service, a ruling or (B) since
the date of the Indentures, there has been a change in the applicable federal
income tax law, in either case to the effect that, and based thereon such
opinion of counsel shall confirm that, the Holders of such Convertible Debt
Securities and JCC Debt Securities will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred; (iii) in the case of Covenant Defeasance, Jacor or JCC, as applicable,
shall have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to such Trustee confirming that the Holders of such
Convertible Debt Securities and JCC Debt Securities will not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (iv) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit or insofar as Events of
Default from bankruptcy or insolvency events are concerned, at any time in the
period ending on the 91st day after the date of deposit; (v) such Legal
Defeasance or Covenant Defeasance shall not result in a breach or violation of,
or constitute a default under the Indenture or any other material agreement or
instrument to which Jacor, JCC or any of their Subsidiaries is a party or by
which Jacor, JCC or any of their Subsidiaries is bound; (vi) Jacor or JCC, as
applicable, shall have delivered to the Trustee an Officers' Certificate stating
that the deposit was not made by Jacor or JCC, as applicable, with the intent of
preferring the holders of such Convertible Debt Securities and JCC Debt
Securities over any other creditors of Jacor or JCC, as applicable, or with the
intent of defeating, hindering,
 
                                       24
<PAGE>

                          DESCRIPTION OF CAPITAL STOCK
 
    Jacor's Certificate of Incorporation authorizes 104,000,000 shares of
capital stock, of which 100,000,000 shares are Jacor Common Stock, 2,000,000
shares are Class A Preferred Stock, $.01 par value and 2,000,000 shares are
Class B Preferred Stock, $.01 par value (together with the Class A Preferred
Stock, the "Preferred Stock"). As of November 5, 1997, 45,564,401 shares of
Jacor Common Stock were issued and outstanding.
 
JACOR COMMON STOCK
 
    Under Jacor's Certificate of Incorporation and Delaware law, the holders of
Jacor Common Stock have no preemptive rights and the Jacor Common Stock has no
redemption, sinking fund, or conversion privileges, except as set forth below.
The holders of Jacor Common Stock are entitled to one vote for each share held
on any matter submitted to the stockholders and do not have the right to
cumulate their votes in the election of directors. All corporate action
requiring stockholder approval, unless otherwise required by law, Jacor's
Certificate of Incorporation or its Bylaws, must be authorized by a majority of
the votes cast. Approval of only a majority of the outstanding voting shares is
required to effect (i) an amendment to Jacor's
 
                                       35
<PAGE>
Certificate of Incorporation, (ii) a merger or consolidation, and (iii) a
disposition of all or substantially all of Jacor's assets. A majority of the
directors on the Jacor Board, as well as a majority of the outstanding voting
shares, have the ability to amend the Jacor Bylaws.
 
    In the event of liquidation, each share of Jacor Common Stock is entitled to
share ratably in the distribution of remaining assets after payment of all
debts, subject to the prior rights in liquidation of any share of Jacor
Preferred Stock issued. Holders of shares of Jacor Common Stock are entitled to
share ratably in such dividends as the Jacor Board of Directors, in its
discretion, may validly declare from funds legally available therefor, subject
to the prior rights of holders of shares of Jacor Preferred Stock as may be
outstanding from time to time. Certain restrictions on the payment of dividends
are imposed under the Credit Facility. See "Risk Factors--Lack of Dividends;
Restrictions on Payments of Dividends."
 
    Jacor's Certificate of Incorporation provides that outstanding shares of
Common Stock held by a Disqualified Holder (as defined below) are subject to
redemption by the Company, by action of the Jacor Board of Directors to the
extent necessary to prevent the loss or secure the reinstatement of any license
or franchise from any governmental agency held by the Company or any of its
subsidiaries, which license or franchise is conditioned upon some or all of the
holders of the Company's stock possessing prescribed qualifications and/or
restrictions. The Certificate of Incorporation prescribes the following terms
and conditions for such redemption: (a) the redemption price of the shares to be
redeemed shall be equal to the lesser of (i) the Fair Market Value (as defined
below) of such shares or (ii) if such stock was purchased by such Disqualified
Holder within one year of the redemption date, such Disqualified Holder's
purchase price for such shares; (b) the redemption price of such shares may be
paid in cash, securities (valued according to a specified method) or any
combination thereof; (c) if less than all the shares held by Disqualified
Holders are to be redeemed, the shares to be redeemed will be selected in such
manner as is determined by the Jacor Board of Directors, which may include
selection first of the most recently purchased shares thereof, selection by lot
or selection in any other manner determined by the Jacor Board of Directors; (d)
at least 30 days written notice of the redemption date must be given to the
record holders of the shares selected to be redeemed (unless waived in writing
by such holder), provided that the redemption date may be the date on which
written notice is given to such record holders if the cash or securities
necessary to effect the redemption shall have been deposited in trust for the
benefit of such record holders and subject to immediate withdrawal by them upon
surrender of the stock certificates for their shares to be redeemed; (e) from
and after the redemption date, any and all rights of whatever nature, which may
be held by the owners of shares called for redemption (including without
limitation any rights to vote or participate in dividends declared on stock of
the same class or series as such shares), shall cease and terminate and they
shall thenceforth be entitled only to receive the cash or securities payable in
respect of such redemption; and (f) such other terms and conditions as the Jacor
Board of Directors may determine.
 
    For purposes of the foregoing provisions of the Certificate of
Incorporation, the following meanings are assigned to certain terms:
"Disqualified Holder" means any holder of shares of capital stock of the Company
whose holding of such stock, either individually or when taken together with the
holding of shares of stock of the Company by any other holders, may result, in
the judgment of the Jacor Board of Directors, in the loss of, or the failure to
secure the reinstatement of, any license or franchise from any governmental
agency held by the Company or any of its subsidiaries to conduct any portion of
the business of the Company or its subsidiaries. "Fair Market Value" of the
Company's stock of any class or series of stock means the average closing price
for such a share for each of the 45 most recent days on which the shares of
stock of such class or series were traded preceding the day on which notice of
redemption was given, except that if such shares of stock of such class or
series are not traded on any securities exchange or in the over-the-counter
market, "Fair Market Value" is any value determined by the Jacor Board of
Directors in good faith. See "Risk Factors -- FCC Regulation of Broadcasting
Industry."
 
JACOR CLASS A AND CLASS B PREFERRED STOCK
 
    No shares of Jacor Preferred Stock have been issued. The Class A Preferred
Stock has full voting rights. The Class B Preferred Stock has no voting rights
except as otherwise provided by law or as lawfully fixed by the Jacor Board of
Directors with respect to a particular series.
 
                                       36
<PAGE>
    Jacor's Certificate of Incorporation authorizes the Jacor Board of Directors
to provide from time to time for the issuance of the shares of Jacor Preferred
Stock and by resolution to establish the terms of each such series, including
(i) the number of shares of the series and the designation thereof, (ii) the
rights in respect of dividends on the shares, (iii) liquidation rights, (iv)
redemption rights, (v) the terms of any purchase, retirement or sinking fund to
be provided for the shares of the series, (vi) terms of conversion, if any,
(vii) restrictions, limitations and conditions, if any, on issuance of
indebtedness of Jacor, (viii) voting rights; and (ix) any other preferences and
other rights and limitations not inconsistent with law, the Certificate of
Incorporation, or any resolution of the Jacor Board of Directors.
 
    The issuance of Jacor Preferred Stock, while providing flexibility in
connection with the possible acquisitions and other corporate purposes, could
among other things adversely affect the rights of holders of Jacor Common Stock,
and, under certain circumstances, make it more difficult for a third party to
gain control of Jacor. In the event that shares of Jacor Preferred Stock are
issued and convertible into shares of Jacor Common Stock the holders of Jacor
Common Stock may experience dilution.
 
    The Prospectus Supplement for any series of Jacor Preferred Stock will state
the terms, if any, on which shares of that series are convertible into shares of
another series of Jacor Preferred Stock or Jacor Common Stock or exchangeable
for another series of Jacor Preferred Stock, Jacor Common Stock or other debt
securities issued hereunder.
 
JACOR DEPOSITARY SHARES
 
    Jacor may, at its option, elect to offer fractional shares of Class A or
Class B Preferred Stock, rather than full shares of Class A or Class B Preferred
Stock. In the event such option is exercised, Jacor will issue receipts for
Jacor Depositary Shares, each of which will represent a fraction (to be set
forth in the Prospectus Supplement relating to the Class A or Class B Preferred
Stock) of a share of such Jacor Preferred Stock.
 
    The share of Class A or Class B Preferred Stock represented by Jacor
Depositary Shares will be deposited under a Deposit Agreement (the "Deposit
Agreement") between Jacor and a bank or trust company selected by Jacor having
its principal office in the United States and having a combined capital and
surplus of at least $50,000,000 (the "Depositary"). Subject to the terms of the
Deposit Agreement, each owner of a Depositary Share will be entitled, in
proportion to the applicable fraction of a share of Class A or Class B Preferred
Stock represented by such Depositary Share, to all the rights and preferences of
the Class A or Class B Preferred Stock represented thereby (including dividend,
voting, redemption, conversion and liquidation rights).
 
    The above summary description of the Jacor Depositary Shares does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the description in the applicable Prospectus Supplement and the
detailed provisions of the Deposit Agreement (which will contain the form of
Depositary Receipt). A copy of the form of Deposit Agreement is available upon
request.
 
CITICASTERS WARRANTS
 
    Jacor issued warrants (the "Citicasters Warrants") pursuant to the terms of
its February 1996 agreement to acquire Citicasters Inc. through a merger (the
"Citicasters Merger") of JCC (formerly JCAC, Inc.) with and into Citicasters
Inc. ("Citicasters"). If all of the Citicasters Warrants are exercised,
4,400,000 shares of Jacor Common Stock would be issued. Each Citicasters Warrant
initially entitles the holder thereof to purchase .2035247 of a share of Jacor
Common Stock at a price of $28.00 per full share (the "Citicasters Price"). The
Citicasters Price and the number of shares of Jacor Common Stock issuable upon
the exercise of each Citicasters Warrant are subject to adjustment in certain
events described below. Each Citicasters
Warrant may be exercised until 5:00 p.m., Eastern Time, on September 18, 2001
(the "Citicasters Expiration Date") in accordance with the terms of the
Citicasters Warrants and Citicasters Warrant Agreement. To the extent that any
Citicasters Warrant remains outstanding after such time, such unexercised
Citicasters Warrant will automatically terminate.
 
                                       37
<PAGE>
    Citicasters Warrants may be exercised by surrendering to the warrant agent a
signed Citicasters Warrant certificate together with the form of election to
purchase on the reverse thereof indicating the warrant holder's election to
exercise all or a portion of the Citicasters Warrants evidenced by such
certificate. Surrendered certificates must be accompanied by payment of the
aggregate Citicasters Price in respect of the Citicasters Warrant to be
exercised, which payment may be made in cash or by certified or bank cashier's
check drawn on a banking institution chartered by the government of the United
States or any state thereof payable to the order of Jacor. No adjustments as to
cash dividends with respect to the Jacor Common Stock will be made upon any
exercise of Citicasters Warrants.
 
    If fewer than all of the Citicasters Warrants evidenced by any certificate
are exercised, the warrant agent will deliver to the exercising warrant holder a
new Citicasters Warrant certificate representing the unexercised Citicasters
Warrants. Jacor will not be required to issue fractional shares of Jacor Common
Stock upon exercise of any Citicasters Warrant and in lieu thereof will pay in
cash an amount equal to the same fraction of the closing price per share of the
Jacor Common Stock, determined as provided in the Citicasters Warrant Agreement.
Jacor has reserved for issuance a number of shares of Jacor Common Stock
sufficient to provide for the exercise of the rights of purchase represented by
the Citicasters Warrants.
 
    A Citicasters Warrant may not be exercised in whole or in part if in the
reasonable opinion of counsel to Jacor the issuance of Jacor Common Stock upon
such exercise would cause Jacor to be in violation of the Communications Act or
the rules and regulations in effect thereunder.
 
    The number of shares of Jacor Common Stock purchasable upon the exercise of
each Citicasters Warrant and the Citicasters Price are subject to the adjustment
in connection with (i) the issuance of a stock dividend to holders of Jacor
Common Stock, a combination or subdivision or issuance by reclassification of
Jacor Common Stock; (ii) the issuance of rights, options or warrants to all
holders of Jacor Common Stock without charge to such holders to subscribe for or
purchase shares of Jacor Common Stock at a price per share which is lower than
the current market price; and (iii) certain distributions by Jacor to the
holders of Jacor Common Stock of evidences of indebtedness or of its assets
(excluding cash dividends, or distributions out of earnings or out of surplus
legally available for dividends) or of convertible securities, all as set forth
in the Citicasters Warrant Agreement. Notwithstanding the foregoing, no
adjustment in the number of shares of Jacor Common Stock issuable upon the
exercise of Citicasters Warrants will be required until such adjustment would
require an increase or decrease of at least one percent (1%) in the number of
shares of Jacor Common Stock purchasable upon the exercise of each Citicasters
Warrant. In addition, Jacor may at its option reduce the Citicasters Price.
 
    In case of any consolidation or merger of Jacor with or into another
corporation, or any sale, transfer or lease to another corporation of all or
substantially all of the property of Jacor, the Citicasters Warrant Agreement
requires that effective provisions be made so that each holder of an outstanding
Citicasters Warrant will have the right thereafter to exercise the Citicasters
Warrant for the kind and amount of securities and property receivable in
connection with such consolidation, merger, sale, transfer or lease by a holder
of the number of shares of Jacor Common Stock for which such Citicasters Warrant
were exercisable immediately prior thereto.
 
    The Citicasters Warrant Agreement may be amended or supplemented without the
consent of the holders of Citicasters Warrants to cure any ambiguity or to
correct or supplement any defective or inconsistent provision contained therein,
or to make such other necessary or desirable changes which shall not adversely
affect the interests of the warrant holders. Any other amendment to the
Citicasters Warrant Agreement requires the consent of warrant holders
representing not less than 50% of the Citicasters Warrants then outstanding
provided that no change in the number or nature of the securities purchasable
upon the exercise of any Citicasters Warrant, or the Citicasters Price therefor,
or the acceleration of the Citicasters Expiration Date, and no change in the
antidilution provisions which would adversely affect the interest of the holders
of Citicasters Warrants, shall be made without the consent of the holder of such
Citicasters Warrant, other than such changes as are specifically prescribed by
the Citicasters Warrant Agreement or are made in compliance with the applicable
law.

    No holder of Citicasters Warrants is entitled to vote or receive dividends
or be deemed for any purpose the holder of Jacor Common Stock until the
Citicasters Warrants are properly exercised as provided in the Citicasters
Warrant Agreement.
 
REGENT WARRANTS
 
    Jacor issued warrants (the "Regent Warrants") pursuant to the terms of its
October 1996 merger agreement (the "Regent Merger Agreement") with Regent
Communications, Inc. ("Regent"), whereby Regent merged with and into Jacor. If
all such Regent Warrants are exercised, 500,000 shares of Jacor Common Stock
would be issued. Each Regent Warrant initially entitles the holder thereof to
purchase .11271 (the "Fraction") of a share of Jacor Common Stock at a price of
$40.00 per full share (the "Regent Price"). The Regent Price and the number of
shares of Jacor Common Stock issuable upon the exercise of each Regent Warrant
are subject to adjustment in certain events described below. Each Regent Warrant
may be exercised until 5:00 pm., Eastern Time, on February 27, 2002 (the "Regent
Expiration Date") in accordance with the terms of the Regent Warrants and the
Regent Warrant Agreement; PROVIDED, HOWEVER, if any of the Regent Warrants are
called for redemption by Jacor, at a price per Regent Warrant equal to $12.00
multiplied by the Fraction, as adjusted from time to time under the terms of the
Regent Warrant Agreement, on or after February 27, 2000, the right to so redeem
the Regent Warrants shall expire at the close of business, New York time, on
such redemption date. To the extent that any Regent Warrant remains outstanding
after such time, such unexercised Regent Warrant will automatically terminate.
 
    Regent Warrants may be exercised by surrendering to the warrant agent a
signed Regent Warrant certificate together with the form of election to purchase
on the reverse thereof indicating the warrant holder's election to exercise all
or a portion of the Regent Warrants evidenced by such certificate. Surrendered
certificates must be accompanied by payment of the aggregate Regent Price in
respect of the Regent Warrants to be exercised, which payment may be made in
cash or by certified or bank cashier's check drawn on a banking institution
chartered by the government of the United States or any state thereof payable to
the order of Jacor. No adjustments as to cash dividends with respect to the
Jacor Common Stock will be made upon any exercise of Regent Warrants.
 
    If fewer than all the Regent Warrants evidenced by any certificate are
exercised, the warrant agent will deliver to the exercising warrant holder a new
Regent Warrant certificate representing the unexercised Regent Warrants. Jacor
will not be required to issue fractional shares of Jacor Common Stock upon
exercise of any Regent Warrant and in lieu thereof will pay in cash an amount
equal to the same fraction of the closing price per share of Jacor Common Stock,
determined as provided in the Regent Warrant Agreement. Jacor has reserved for
issuance a number of shares of Jacor Common Stock sufficient to provide for the
exercise of the rights of purchase represented by the Regent Warrants.
 
    A Regent Warrant may not be exercised in whole or in part if in the
reasonable opinion of counsel to Jacor the issuance of Jacor Common Stock upon
such exercise would cause Jacor to be in violation of the Communications Act or
the rules and regulations in effect thereunder.
 
    The number of shares of Jacor Common Stock purchasable upon the exercise of
each Regent Warrant and the Regent Price are subject to adjustment in connection
with (i) the issuance of a stock dividend to holders of Jacor Common Stock, a
combination or subdivision or issuance by reclassification of Jacor Common
Stock; (ii) the issuance of rights, options or warrants to all holders of Jacor
Common Stock without charge to such holders to subscribe for or purchase shares
of Jacor Common Stock at a price per share which is lower than the current
market price; and (iii) certain distributions by Jacor to the holders of Jacor
Common Stock of evidences of indebtedness or of its assets (excluding cash
dividends or distributions pursuant to an announced policy of Jacor payable out
of earnings or out of surplus legally available for dividends) or of convertible
securities, all as set forth in the Regent Warrant Agreement. Notwithstanding
the foregoing, no adjustment in the number of shares of Jacor Common Stock
issuable upon the exercise of the Regent Warrants will be required until such
adjustment would require an increase or decrease of at least
 
                                       39
<PAGE>
one percent (1%) in the number of shares of Jacor Common Stock purchasable upon
the exercise of each Regent Warrant. In addition, Jacor may at its option reduce
the Regent Price to any amount deemed appropriate by the Jacor Board of
Directors.
 
    In case of any consolidation or merger of Jacor with or into another
corporation, or any sale, transfer or lease to another corporation of all or
substantially all the property of Jacor, the Regent Warrant Agreement requires
that effective provisions be made so that each holder of an outstanding Regent
Warrant will have the right thereafter to exercise the Regent Warrant for the
kind and amount of securities and property receivable in connection with such
consolidation, merger, sale, transfer or lease by a holder of the number of
shares of Jacor Common Stock for which such Regent Warrant were exercisable
immediately prior thereto.
 
    The Regent Warrant Agreement may be amended or supplemented without the
consent of the holders of Regent Warrants to cure any ambiguity or to correct or
supplement any defective or inconsistent provision contained therein, or to make
such other necessary or desirable changes which shall not adversely affect the
interests of the warrant holders. Any other amendment to the Regent Warrant
Agreement shall require the consent of warrant holders representing not less
than 50% of the Regent Warrants then outstanding provided that no change in the
number or nature of the securities purchasable upon the exercise of any Regent
Warrant, or the Regent Price therefor, or the acceleration of the Regent
Expiration Date, and no change in the antidilution provisions which would
adversely affect the interests of the holders of Regent Warrants, shall be made
without the consent of the holder of such Regent Warrant, other than such
changes as are specifically prescribed by the Regent Warrant Agreement or are
made in compliance with applicable law.
 
    No holder of Regent Warrants is entitled to vote or receive dividends or be
deemed for any purpose the holder of Jacor Common Stock until the Regent
Warrants are properly exercised as provided in the Regent Warrant Agreement.
 
DELAWARE ANTITAKEOVER STATUTE
 
    Jacor is subject to the "business combination" statute of the Delaware
General Corporation Law (Section 203). In general, such statute prohibits a
publicly held Delaware corporation from engaging in various "business
combination" transactions with any "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
"interested stockholder," unless (i) such transaction is approved by the Board
of Directors prior to the date the "interested stockholder" obtains such status,
(ii) upon consummation of the transaction the interested stockholder
beneficially owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned by (a) persons
who are directors and also officers and (b) employee stock plans in which
employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer
or (iii) the "business combination" is approved by the Board of Directors and
authorized at an annual or special meeting of stockholders by the affirmative
vote of at least 66 2/3% of the outstanding voting stock which is not owned by
the "interested stockholder." A "business combination" includes mergers, asset
sales and other transactions resulting in a financial benefit to an "interested
stockholder." An "interested stockholder" is a person who, together with
affiliates and associates, owns (or within three years, did own) 15% or more of
the corporation's voting stock. The statute could prohibit or delay mergers or
other takeover or change in control attempts with respect to Jacor and,
accordingly, may discourage attempts to acquire Jacor.
 
REGISTRAR AND TRANSFER AGENT
 
    ChaseMellon Shareholder Services LLC is the registrar and transfer agent for
the Jacor Common Stock and the warrant agent for the Citicasters Warrants and
the Regent Warrants.

                          DESCRIPTION OF INDEBTEDNESS
 
    The summaries contained herein of certain of the indebtedness of Jacor and
JCC do not purport to be complete and are qualified in their entirety by
reference to the provisions of the various agreements and indentures related
thereto, which are filed as exhibits to the Registration Statement of which this
Prospectus is a part and to which reference is hereby made.
 
CREDIT FACILITY
 
    JCC amended and restated its credit facility with a syndicate of banks and
other financial institutions on September 16, 1997 (the "Credit Facility"). The
Credit Facility provides availability of up to $1.15 billion of loans to JCC in
two components: (i) a revolving credit facility of up to $750.0 million with
mandatory semi-annual commitment reductions beginning June 30, 2000 and a final
maturity date of December 31, 2004; and (ii) a term loan of $400.0 million with
scheduled semi-annual reductions beginning December 31, 1999 and a final
maturity date of December 31, 2004. The Credit Facility bears interest at a rate
that fluctuates with an applicable margin based on Jacor's leverage ratio plus a
bank base rate or a Eurodollar base rate, as applicable.
 
    The loans under the Credit Facility are guaranteed by each of Jacor's direct
and indirect subsidiaries other than certain immaterial subsidiaries. JCC's
obligations under the Credit Facility are secured by a first priority lien on
the capital stock of Jacor's and JCC's subsidiaries, an assignment of all
intercompany debt and of certain time brokerage agreements, and by the guarantee
of JCC's parent, Jacor.
 
    The Credit Facility contains covenants and provisions that restrict, among
other things, JCC's ability to: (i) incur additional indebtedness; (ii) incur
liens on its property; (iii) make investments and advances; (iv) enter into
guarantees and other contingent obligations; (v) merge or consolidate with or
acquire another person or engage in other fundamental changes; (vi) engage in
certain sales of assets; (vii) engage in certain transactions with affiliates;
and (viii) make restricted junior payments. The Credit Facility also requires
the satisfaction of certain financial performance criteria (including a
consolidated interest coverage ratio, a debt-to-operating cash flow ratio and a
consolidated operating cash flow available for fixed charges ratio) and the
repayment of loans under the Credit Facility with proceeds of certain sales of
assets and debt issuances.
 
    Events of default under the Credit Facility include various events of
default customary for such type of agreement, such as failure to pay scheduled
payments when due, cross defaults on other indebtedness, change of control
events under other indebtedness (including the LYONs, 10 1/8% Notes, 9 3/4%
Notes and 8 3/4% Notes) and certain events of bankruptcy, insolvency and
reorganization. In addition, the Credit Facility includes events of default for
JCC relating to the cessation of any lien on any of the collateral under the
Credit Facility as a perfected first priority lien and the failure of
Zell/Chilmark designees to represent at least 30% of the Jacor Board of
Directors.
 
    For purposes of the Credit Facility, a change of control includes the
occurrence of any event that triggers a change of control under the LYONs,
10 1/8% Notes, 9 3/4% Notes or 8 3/4% Notes. Such change of control under the
Credit Facility would constitute an event of default which would give the
syndicate the right to accelerate the unpaid principal amounts due under the
Credit Facility. Upon such acceleration, there is no assurance that JCC will
have funds available to fund such repayment or that such funds will be available
on terms acceptable to JCC.
 
10 1/8% NOTES
 
    In June 1996, JCAC, Inc. (a predecessor to JCC) conducted an offering (the
"10 1/8% Notes Offering") whereby JCAC, Inc. issued and sold 10 1/8% Senior
Subordinated Notes due 2006 (the "10 1/8% Notes") in an aggregate principal
amount of $100.0 million. The 10 1/8% Notes were issued pursuant to an Indenture
between JCAC, Inc. and First Trust of Illinois, National Association, as Trustee
(the "10 1/8% Note Indenture"). The 10 1/8% Notes have interest payment dates of
June 15 and December 15, commencing on December 15, 1996, and mature on June 15,
2006.
 
                                       41
<PAGE>
    The 10 1/8% Note Indenture contains certain covenants which impose certain
limitations and restrictions on the ability of JCC and the Subsidiary Guarantors
to incur additional indebtedness, pay dividends or make other distributions,
make certain loans and investments, apply the proceeds of asset sales (and use
the proceeds thereof), create liens, enter into certain transactions with
affiliates, merge, consolidate or transfer substantially all its assets and make
investments in unrestricted subsidiaries.
 
    If a change of control occurs, JCC will be required to offer to repurchase
all outstanding 10 1/8% Notes at a price equal to 101% of their principal
amount, plus accrued and unpaid interest, if any, to the date of repurchase.
There can be no assurance that JCC will have sufficient funds to purchase all of
the 10 1/8% Notes in the event of a change of control offer or that JCC would be
able to obtain financing for such purpose on favorable terms, if at all. In
addition, the Credit Facility restricts JCC's ability to repurchase the 10 1/8%
Notes, including pursuant to a change of control offer. Furthermore, a change of
control under the 10 1/8% Note Indenture will result in a default under the
Credit Facility.
 
    As used herein, a "Change of Control" will mean (i) any merger or
consolidation of JCC with or into any person or any sale, transfer or other
conveyance, whether direct or indirect, of all or substantially all of any of
the assets of JCC, on a consolidated basis, in one transaction or a series of
related transactions, if, immediately after giving effect to such
transaction(s), any "person" or "group" (as such terms are used for purposes of
Sections 13(d) and 14(d) of the Exchange Act, whether or not applicable) (other
than an Excluded Person) is or becomes the "beneficial owner," directly or
indirectly, of more than 50% of the total voting power in the aggregate normally
entitled to vote in the election of directors, managers, or trustees, as
applicable, of the transferee(s) or surviving entity or entities, (ii) any
"person" or "group" (as such terms are used for purposes of Sections 13(d) and
14(d) of the Exchange Act, whether or not applicable) (other than an Excluded
Person) is or becomes the "beneficial owner," directly or indirectly, of more
than 50% of the total voting power in the aggregate of all classes of Capital
Stock of JCC then outstanding normally entitled to vote in elections of
directors, or (iii) during any period of 12 consecutive months after the Issue
Date, individuals who at the beginning of any such 12-month period constituted
the Board of Directors of JCC (together with any new directors whose election by
such Board or whose nomination for election by the shareholders of JCC was
approved by a vote of a majority of the directors then still in office who were
either directors at the beginning of such period or whose election or nomination
for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors of JCC then in office.
 
    The events of default under the 10 1/8% Note Indenture include various
events of default customary for such type of agreement, including the failure to
pay principal and interest when due on the 10 1/8% Notes, cross defaults on
other indebtedness for borrowed monies in excess of $5.0 million (which
indebtedness would therefore include the Credit Facility, LYONs, 9 3/4% Notes
and 8 3/4% Notes) and certain events of bankruptcy, insolvency and
reorganization.
 
LIQUID YIELD OPTION-TM- NOTES DUE 2011
 
    Also in June 1996, Jacor conducted an offering (the "LYONs Offering")
whereby Jacor issued and sold Senior Liquid Yield Option-TM- Notes due June 12,
2011 (the "LYONs due 2011") in the aggregate principal amount at maturity of
$259.9 million. Each LYON due 2011 had an Issue Price of $443.14 and a principal
amount at maturity of $1,000. The LYONs due 2011 were issued pursuant to an
Indenture between Jacor and The Bank of New York, as Trustee (the "1996 LYONs
Indenture").
 
    Each LYON due 2011 is convertible, at the option of the Holder, at any time
on or prior to maturity, unless previously redeemed or otherwise purchased, into
Jacor Common Stock at a conversion rate of 13.412 shares per LYON due 2011. The
conversion rate will not be adjusted for accrued original issue discount, but
will be subject to adjustment upon the occurrence of certain events affecting
the Jacor Common Stock. Upon conversion, the Holder will not receive any cash
payment representing accrued original issue discount; such accrued original
issue discount will be deemed paid by the Jacor Common Stock received by the
Holder on conversion.
 
                                       42
<PAGE>
    The LYONs due 2011 are not redeemable by Jacor prior to June 12, 2001.
Thereafter, the LYONs due 2011 are redeemable for cash at any time at the option
of Jacor, in whole or in part, at redemption prices equal to the issue price
plus accrued original issue discount to the date of redemption.
 
    The LYONs due 2011 will be purchased by Jacor, at the option of the Holder,
on June 12, 2001 and June 12, 2006, for a Purchase Price of $581.25 and $762.39
(representing issue price plus accrued original issue discount to each date),
respectively, representing a 5.50% yield per annum to the Holder on such date,
computed on a semiannual bond equivalent basis. Jacor, at its option, may elect
to pay the purchase price on any such purchase date in cash or Jacor Common
Stock, or any combination thereof. In addition, as of 35 business days after the
occurrence of a change in control of Jacor occurring on or prior to June 12,
2001, each LYON due 2011 will be purchased for cash, by Jacor, at the option of
the Holder, for a change in control purchase price equal to the issue price plus
accrued original issue discount to the change in control purchase date set for
such purchase. The change in control purchase feature of the LYONs due 2011 may
in certain circumstances have an antitakeover effect.
 
    Under the 1996 LYONs Indenture, a "Change in Control" of Jacor is deemed to
have occurred at such time as (i) any person (as the term "person" is used in
Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) other than
Zell/Chilmark, Jacor, any Subsidiary of Jacor, or any employee benefit plan of
either Jacor or any Subsidiary of Jacor, files a Schedule 13D or 14D-1 under the
Exchange Act (or any successor schedule, form or report) disclosing that such
person has become the beneficial owner of 50% or more of the Jacor Common Stock
or other capital stock of Jacor into which such Jacor Common Stock is
reclassified or changed, with certain exceptions, or (ii) there shall be
consummated any consolidation or merger of Jacor (a) in which Jacor is not the
continuing or surviving corporation or (b) pursuant to which the Jacor Common
Stock would be converted into cash, securities or other property, in each case,
other than a consolidation or merger of Jacor in which the holders of Jacor
Common Stock immediately prior to the consolidation or merger own, directly or
indirectly, at least a majority of Jacor Common Stock of the continuing or
surviving corporation immediately after the consolidation or merger. A Change of
Control under the 1996 LYONs Indenture constitutes an event of default under the
Credit Facility. See "-- The Credit Facility."
 
    The 1996 LYONs Indenture includes various events of default customary for
such type of agreement, such as cross defaults on other indebtedness for
borrowed monies in excess of $10.0 million (which indebtedness would therefore
include the Credit Facility, 9 3/4% Notes, 10 1/8% Notes and 8 3/4% Notes) and
certain events of bankruptcy, insolvency and reorganization.
 
9 3/4% NOTES
 
    In December 1996, JCC conducted an offering (the "9 3/4% Notes Offering")
whereby JCC issued and sold 9 3/4% Senior Subordinated Notes due 2006 (the
"9 3/4% Notes") in an aggregate principal amount of $170.0 million. The 9 3/4%
Notes were issued pursuant to an Indenture between JCC and The Bank of New York,
as Trustee (the "9 3/4% Note Indenture"). The 9 3/4% Notes have interest payment
dates of June 15 and December 15, commencing on June 15, 1997, and mature on
December 15, 2006.
 
    The 9 3/4% Note Indenture contains certain covenants which impose certain
limitations and restrictions on the ability of JCC and the Subsidiary Guarantors
to incur additional indebtedness, pay dividends or make other distributions,
make certain loans and investments, apply the proceeds of asset sales (and use
the proceeds thereof), create liens, enter into certain transactions with
affiliates, merge, consolidate or transfer substantially all its assets and make
investments in unrestricted subsidiaries.
 
    If a change of control occurs, JCC will be required to offer to repurchase
all outstanding 9 3/4% Notes at a price equal to 101% of their principal amount,
plus accrued and unpaid interest, if any, to the date of repurchase. There can
be no assurance that JCC will have sufficient funds to purchase all of the
9 3/4% Notes in the event of a change of control offer or that JCC would be able
to obtain financing for such purpose on favorable terms, if at all. In addition,
the Credit Facility restricts JCC's ability to repurchase the 9 3/4% Notes,
including pursuant to a change of control offer. Furthermore, a change of
control under the 9 3/4% Note Indenture will result in a default under the
Credit Facility.
 
                                       43
<PAGE>
    As used herein, a "Change of Control" will mean (i) any merger or
consolidation of JCC with or into any person or any sale, transfer or other
conveyance, whether direct or indirect, of all or substantially all of any of
the assets of JCC, on a consolidated basis, in one transaction or a series of
related transactions, if, immediately after giving effect to such
transaction(s), any "person" or "group" (as such terms are used for purposes of
Sections 13(d) and 14(d) of the Exchange Act, whether or not applicable) (other
than an Excluded Person) is or becomes the "beneficial owner," directly or
indirectly, of more than 50% of the total voting power in the aggregate normally
entitled to vote in the election of directors, managers, or trustees, as
applicable, of the transferee(s) or surviving entity or entities, (ii) any
"person" or "group" (as such terms are used for purposes of Sections 13(d) and
14(d) of the Exchange Act, whether or not applicable) (other than an Excluded
Person) is or becomes the "beneficial owner," directly or indirectly, of more
than 50% of the total voting power in the aggregate of all classes of Capital
Stock of JCC then outstanding normally entitled to vote in elections of
directors, or (iii) during any period of 12 consecutive months after the Issue
Date, individuals who at the beginning of any such 12-month period constituted
the Board of Directors of JCC (together with any new directors whose election by
such Board or whose nomination for election by the shareholders of JCC was
approved by a vote of a majority of the directors then still in office who were
either directors at the beginning of such period or whose election or nomination
for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors of JCC then in office.
 
    The events of default under the 9 3/4% Note Indenture include various events
of default customary for such type of agreement, including the failure to pay
principal and interest when due on the 9 3/4% Notes, cross defaults on other
indebtedness for borrowed monies in excess of $5.0 million (which indebtedness
would therefore include the Credit Facility, LYONs due 2011, 10 1/8% Notes and
8 3/4% Notes) and certain events of bankruptcy, insolvency and reorganization.
 
8 3/4% NOTES
 
    In June 1997, JCC conducted an offering (the "8 3/4% Notes Offering")
whereby JCC issued and sold 8 3/4% Senior Subordinated Notes due 2007 (the
"8 3/4% Notes") in an aggregate principal amount of $150.0 million. The 8 3/4%
Notes were issued pursuant to an Indenture between JCC and The Bank of New York,
as Trustee (the "8 3/4% Note Indenture"). The 8 3/4% Notes have interest payment
dates of June 15 and December 15, commencing on December 15, 1997, and mature on
June 15, 2007.
 
    Upon issuance, the 8 3/4% Notes were subject to certain trading restrictions
but were eligible for trading in the Private Offering, Resales and Trading
through Automated Linkages market. JCC and the Subsidiary Guarantors agreed, for
the benefit of the holders of the 8 3/4% Notes, that they would use their
reasonable best efforts to file a registration statement within 90 days of the
date of issuance of the 8 3/4% Notes relating to a registered exchange offer of
the 8 3/4% Notes for new 8 3/4% Notes with substantially identical terms except
that the new 8 3/4% Notes will not contain terms with respect to transfer
restrictions. JCC and the Subsidiary Guarantors are expected to commence the
exchange offer on or about December 1, 1997.
 
    The 8 3/4% Note Indenture contains certain covenants which impose certain
limitations and restrictions on the ability of JCC and the Subsidiary Guarantors
to incur additional indebtedness, pay dividends or make other distributions,
make certain loans and investments, apply the proceeds of asset sales (and use
the proceeds thereof), create liens, enter into certain transactions with
affiliates, merge, consolidate or transfer substantially all its assets and make
investments in unrestricted subsidiaries.
 
    If a change of control occurs, JCC will be required to offer to repurchase
all outstanding 8 3/4% Notes at a price equal to 101% of their principal amount,
plus accrued and unpaid interest, if any, to the date of repurchase. There can
be no assurance that JCC will have sufficient funds to purchase all of the
8 3/4% Notes in the event of a change of control offer or that JCC would be able
to obtain financing for such purpose on favorable terms, if at all. In addition,
the Credit Facility restricts JCC's ability to repurchase the 8 3/4% Notes,
including pursuant to a change of control offer. Furthermore, a change of
control under the 8 3/4% Note Indenture will result in a default under the
Credit Facility.
 
    As used herein, a "Change of Control" will mean (i) any merger or
consolidation of JCC with or into any person or any sale, transfer or other
conveyance, whether direct or indirect, of all or substantially all or
 
                                       44
<PAGE>
any of the assets of JCC, on a consolidated basis, in one transaction or a
series of related transactions, if, immediately after giving effect to such
transaction(s), any "person" or "group" (as such terms are used for purposes of
Sections 13(d) and 14(d) of the Exchange Act, whether or not applicable) (other
than an Excluded Person) is or becomes the "beneficial owner," directly or
indirectly, of more than 50% of the total voting power in the aggregate normally
entitled to vote in the election of directors, managers, or trustees, as
applicable, of the transferee(s) or surviving entity or entities, (ii) any
"person" or "group" (as such terms are used for purposes of Sections 13(d) and
14(d) of the Exchange Act, whether or not applicable) (other than an Excluded
Person) is or becomes the "beneficial owner," directly or indirectly, of more
than 50% of the total voting power in the aggregate of all classes of Capital
Stock of JCC then outstanding normally entitled to vote in elections of
directors, or (iii) during any period of 12 consecutive months after the Issue
Date, individuals who at the beginning of any such 12-month period constituted
the Board of Directors of JCC (together with any new directors whose election by
such Board or whose nomination for election by the shareholders of JCC was
approved by a vote of a majority of the directors then still in office who were
either directors at the beginning of such period or whose election or nomination
for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors of JCC then in office.
 
    The events of default under the 8 3/4% Note Indenture include various events

                              PLAN OF DISTRIBUTION
 
    Jacor and/or JCC may sell the Securities to one or more underwriters for
public offering and sale in the United States or eligible foreign jurisdictions
by them or may sell the Securities to investors directly or through agents. Any
such underwriter or agent involved in the offer and sale of Securities will be
named in the applicable Prospectus Supplement. Jacor and JCC have reserved the
right to sell Securities directly to investors on its own behalf in those
jurisdictions where and in such manner as it is authorized to do so.
 
    Underwriters may offer and sell Securities at a fixed price or prices, which
may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices, or at negotiated prices. Jacor and/or
JCC also may, from time to time, authorize dealers, acting as Jacor's agents, to
offer and sell Securities upon the terms and conditions as are set forth in the
applicable Prospectus Supplement. In connection with the sale of Securities,
underwriters may receive compensation from Jacor and/or JCC in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of the Securities for whom they may act as agent. Underwriters may
sell Securities to or through dealers, and such dealers may receive compensation
in the form of discounts, concessions or commissions from the underwriters
and/or commissions from the purchasers for whom they may act as agent.
 
    Any underwriting compensation paid by Jacor and/or JCC to underwriters or
agents in connection with the offering of Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Dealers and agents
participating in the distribution of Securities may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the Securities may be deemed to be underwriting
discounts and commissions. Underwriters, dealers and agents may be entitled,
under agreements entered into with Jacor and/or JCC, to indemnification against
and contribution toward certain civil liabilities, including liabilities under
the Securities Act.
 
    If so indicated in the Prospectus Supplement, Jacor and/or JCC will
authorize dealers acting as Jacor's and/or JCC's agents to solicit offers by
certain institutions to purchase the Securities from Jacor and/or JCC at the
public offering price set forth in the applicable Prospectus Supplement pursuant
to delayed delivery contracts ("Contracts") providing for payment and delivery
on the date or dates stated in such Prospectus Supplement. Each Contract will be
for an amount not less than the amounts stated in the applicable Prospectus
Supplement. Institutions with whom Contracts, when authorized, may be made
include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions, and other
institutions but will in all cases be subject to the approval of Jacor and/or
JCC. Contracts will not be subject to any conditions except (i) the purchase by
the institution of the Securities covered by its Contract shall not at the time
of delivery be prohibited under the laws of any jurisdiction in the United
States to which such institution is subject, and (ii) if the Securities are
being sold to underwriters, Jacor and/or JCC shall have sold to such
underwriters the total amount specified in the applicable Prospectus Supplement.
A commission indicated in the applicable Prospectus Supplement will be paid to
underwriters and agents soliciting purchases of Securities pursuant to Contracts
accepted by Jacor and/or JCC.
 
    Underwriters and dealers may engage in passive market making transactions in
Jacor Common Stock in accordance with Rule 103 of Regulation M promulgated by
the Commission. In general, a passive market maker may not bid for or purchase
Jacor Common Stock at a price that exceeds the highest independent bid. In
addition, the net daily purchases made by any passive market maker generally may
not exceed 30% of its average daily trading volume in Jacor Common Stock during
a specified two month prior period, or 200 shares, whichever is greater. A
passive market maker must identify passive market making bids on the Nasdaq
electronic inter-dealer reporting system. Passive market making may stabilize or
maintain the market price of Jacor Common Stock above independent market levels.
Underwriters and dealers are not required to engage in passive market making and
may end passive market making activities at any time.
