                          -------------------------------

<PAGE>

     From time to time, Radio One, Inc., a Delaware corporation (the "Company"),
may enter into one or more warrant agreements that provide for the issuance and
sale of warrants ("Warrants") to purchase shares of the Company's (Class D
Common Stock, $0.001 par value) (Preferred Stock, $0.001 par value)
(collectively "Shares"). The standard provisions set forth herein may be
included or incorporated by reference in any such warrant agreement (a "Warrant
Agreement"). The Warrant Agreement, including the provisions incorporated
therein by reference, is herein referred to as this "Agreement." The person
named as the "Warrant Agent" in the first paragraph of the Warrant Agreement is
herein referred to as the "Warrant Agent." Unless otherwise defined in this
Agreement or in the Warrant Agreement, as the case may be, terms defined in the
Warrant Agreement are used herein as therein defined and terms defined herein
are used in the Warrant Agreement as herein defined.

                                    ARTICLE 1
            ISSUANCE, EXECUTION AND DELIVERY OF WARRANT CERTIFICATES

     1.1 Issuance of Warrant Certificates. Each Warrant Certificate shall
evidence one or more Warrants. Each Warrant evidenced thereby shall represent
the right, subject to the provisions contained herein and therein, to purchase
such numbers of Shares as are set forth in the Warrant Agreement. The number of
Warrants which may be issued and delivered under this Agreement is unlimited.

     There shall be established in or pursuant to a resolution of the Board of
Directors of the Company or any duly authorized committee thereof or established
in one or more warrant agreements supplemental hereto, prior to the issuance of
any Warrants: the designation of such Warrants; if the Warrants are issued
together as a unit with any other securities of the Company, the date after
which the Warrants shall be freely tradable separately from such other
securities (the "Distribution Date"); if the Company may at its option or under
circumstances described therein provide for an earlier Distribution Date; the
expiration date, pursuant to Section 2.2; the exercise price and any form of
consideration other than lawful money of the United States of America by which
the exercise price may be paid pursuant to Section 2.1; the Call Price, Call
Date and Call Terms pursuant to Section 3.4; the limitations, if any, upon the
Reduced Warrant Price and the Reduced Warrant Price Period, pursuant to Section
3.5; the circumstances, if any, under which the Exercise Price and the number of
Shares purchasable upon the exercise of each Warrant and the number of Warrants
outstanding are subject to adjustment and the manner of making any such
adjustment.

     1.2 Execution and Delivery of Warrant Certificates. Each Warrant
Certificate, whenever issued, shall be in registered form substantially in such
form or forms as shall be established by the Company from time to time pursuant
to one or more resolutions of the Board of Directors of the Company or in one or
more warrant agreements supplemental hereto, and in each case shall be dated as
of the date of issuance thereof, and may have such letters, numbers or other
marks of identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as the officers of the Company executing the
Warrant Certificate may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Agreement, or as may be required to comply with (i) any law or with any rule or
regulation made pursuant thereto or (ii) any rule or regulation of any stock
exchange on which the Warrant Certificates may be listed, or to conform to
usage. The Warrant Certificates shall be signed on behalf of the Company by its
Chairperson of the Board of Directors, a Vice Chairperson of the Board of
Directors, its President, a Vice President or its Treasurer and attested by its
Secretary or Assistant Secretary, under its corporate seal. Such signatures may
be manual or facsimile signatures of such authorized officers and may be
imprinted or otherwise reproduced on the Warrant Certificates. The seal of the
Company may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Warrant Certificates.

     No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by
the Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence that the Warrant Certificate so countersigned has been duly
delivered hereunder.

     If any officer of the Company who shall have signed any of the Warrant
Certificates either manually or by facsimile signature shall cease to be such
officer before the Warrant Certificates so signed shall have been countersigned
and delivered to the Warrant Agent, such Warrant Certificates nevertheless may
be countersigned and delivered as though the person who signed such Warrant
Certificates had not cease to be such officer of the Company. Any Warrant

                                        1

<PAGE>

Certificate may be signed on behalf of the Company by such persons as, at the
actual date of the execution of such Warrant Certificate, shall be the proper
officers of the Company, although at the date of the execution of this Agreement
any such persons was not an officer.

     1.3 Registration and Countersignature. The Warrant Agent shall, upon
receipt of Warrant Certificates, duly executed on behalf of the Company,
countersign the Warrant Certificates evidencing Warrants to purchase the number
of Shares set forth in the Warrant Agreement and shall deliver such Warrant
Certificates to the appropriate person or entity upon the written order of the
Company. After the original issuance of the Warrant Certificates, the Warrant
Agent shall countersign a Warrant Certificate only if the Warrant Certificate is
issued in exchange or substitution for, or in connection with the registration
of transfer of, one or more previously countersigned Warrant Certificates, as
hereinafter provided. The Warrant Certificates shall not be valid for any
purpose unless so countersigned.

     The Warrant Agent's countersignature on all Warrants shall be in
substantially the following form:

                                    [NAME OF WARRANT AGENT],
                                    as Warrant Agent


                                    By
                                      -----------------------------------------
                                              Authorized Signatory

                                    ARTICLE 2
          WARRANT PRICE, DURATION AND EXERCISE OF WARRANT CERTIFICATES

     2.1 Warrant Price. The exercise price of each Warrant and any other form of
consideration other than lawful money of the United States of America by which
the exercise price may be paid shall be as set forth in the Warrant Agreement.
The purchase price (including moneys and such other consideration) of the Shares
upon exercise of the Warrants is referred to in this Agreement as the "Warrant
Price" and is payable in full at the time of exercise.

     2.2 Duration of Warrant Certificates. Warrant Certificates may be exercised
in whole at any time, and in part from time to time, during the period set forth
in the Warrant Agent (the "Expiration Date"). Each Warrant Certificate not
exercised on or before the close of business on the Expiration Date shall become
void, and all rights of the holder thereunder and under this Agreement shall
cease.

     2.3 Exercise of Warrant Certificates.


         (a) Prior to the Expiration Date, a Warrant Certificate, if
countersigned by the Warrant Agent, may be exercised in whole or in part by
providing certain information set forth on the reverse side of the Warrant
Certificate and, unless otherwise provided pursuant to Section 2.1, by paying in
full (in cash or by certified or official bank check in New York Clearing House
funds or by bank wire transfer in immediately available funds), in United States
dollars, the Warrant Price for the Shares as to which the Warrant Certificate is
exercised, to the Warrant Agent at its corporate trust office at the address set
forth in the Warrant Agreement. The payment must specify the name of the holder
and the number of Warrants exercised by such holder. Warrants will be deemed to
have been exercised upon receipt by the Warrant Agent of the Warrant Price and
the Warrant Certificate properly completed and duly executed by the registered
holder or holders thereof or by the duly appointed legal representative thereof
or by a duly authorized attorney, such signature to be guaranteed (under the
Medallion Program) by a bank or trust company, by a broker or dealer which is a
member of the National Association of Securities Dealers, Inc. ("NASD") or by a
member of a national securities exchange. If the Warrant Agent receives moneys
in payment of the Warrant Price, the Warrant Agent shall deposit all funds
received by it in the account of the Company maintained with it for such
purpose. If the Warrant Agent receives consideration other than moneys for
purpose. If the Warrant Agent receives consideration other than moneys for
Warrants, the Warrant Agent shall deliver such consideration directly to the
Company. In either case, the Warrant Agent shall advise the Company by telex or
telecopy [periodically, as agreed upon by the Warrant Agent and the Company] as
to the Warrant Certificates that have been exercised and the amount of moneys
deposited to its account or the type and amount of other consideration to be
delivered to it.

                                        2

<PAGE>

         (b) The Warrant Agent shall, from time to time, as promptly as
practicable, advise the Company of (i) the number of Warrants exercised, (ii)
the instructions of each holder of the Warrant Certificates evidencing such
Warrants with respect to delivery of the Shares to which such holder is entitled
upon such exercise, (iii) delivery of Warrant Certificates evidencing the
balance, if any, of the Warrants remaining after such exercise and (iv) such
other information as the Company shall reasonably require.

         (c) As soon as practicable after receipt of payment of the Warrant
Price and the Warrant Certificate properly completed and duly executed at the
corporate trust office of the Warrant Agent, the Company shall issue or deliver,
upon the order of the holder of such Warrant Certificate, the Shares in
authorized denominations to which such holder is entitled, in fully registered
form in such name or names as maybe directed by such holder, and if such Warrant
Certificate was not exercised in full, upon request of the holder a new Warrant
Certificate evidencing the number of Warrants remaining unexercised shall be
issued if sufficient time remains prior to the Expiration Date.

         (d) The Company will pay all documentary stamp taxes attributable to
the initial issuance of Warrants and of Shares upon the exercise of Warrants;
provided, however, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue of
any Warrant Certificates or any certificates for Shares in a name other than the
registered holder of a Warrant Certificate surrendered upon the exercise of a
Warrant, and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

                                    ARTICLE 3
     OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT CERTIFICATES

     3.1 No Rights as Securityholders Conferred by Warrant Certificates. No
Warrant Certificate shall entitle the holder thereof to any of the rights of a
stockholder of the Company, including the right to receive the payment of
dividends on or vote the Shares.

     3.2 Lost, Stolen, Mutilated or Destroyed Warrant Certificates. Upon receipt
by the Company and the Warrant Agent of evidence reasonably satisfactory to them
of the ownership and the loss, theft, destruction or mutilation of the Warrant
Certificate, and of indemnity reasonably satisfactory to them, and, in the case
of mutilation, upon surrender thereof to the Warrant Agent for cancellation,
then, in the absence of notice to the Company or the Warrant Agent that such
Warrant Certificate has been acquired by a bona fide purchaser, the Company
shall execute, and an authorized officer of the Warrant Agent shall manually
countersign and deliver, in exchange for or in lieu of the lost, stolen or
destroyed or mutilated Warrant Certificate, a new Warrant Certificate of the
same tenor and for a like number of Warrants. Upon the issuance of any new
Warrant Certificate under this Section, the Company may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expense (including the fees and expenses of
the Warrant Agent) in connection therewith. Every substitute Warrant Certificate
executed and delivered pursuant to this Section in lieu of any lost, stolen or
destroyed Warrant Certificate shall constitute an additional contractual
obligation of the Company, whether or not the lost, stolen or destroyed Warrant
Certificate shall be at any time enforceable by anyone, and shall be entitled to
the benefits of this Agreement equally and proportionately with any and all
other Warrant Certificates duly executed and delivered hereunder. The provisions
of this Section are exclusive and shall preclude (to the extent lawful) any and
all other rights or remedies with respect to the replacement of mutilated, lost,
stolen or destroyed Warrant Certificates.

     3.3 Holder of Warrant Certificate May Enforce Rights. Notwithstanding any
of the provisions of this Agreement, any holder of any Warrant Certificate,
without the consent of the Warrant Agent, the holder of any Shares or the holder
of any other Warrant Certificate, may, in his or her own behalf and for his or
her own benefit, enforce, and may institute and maintain any audit, action or
proceeding against the Company to enforce or otherwise in respect of, his right
to exercise his or her Warrant Certificate in the manner provided in his or her
Warrant Certificate and in his or her Agreement.

     3.4 Call of Warrants by the Company. If so provided in the Warrant
Agreement, the Company shall have the right to call and repurchase any or all
Warrants at the price (the "Call Price") and on or after the date (the "Call
Date") and

                                        3

<PAGE>

upon the terms (the "Call Terms") as shall be established from time
to time in or pursuant to resolutions of the Board of Directors of the Company
or in the Warrant Agreement before the issuance of such Warrants. Notice of such
Call Price, Call Date and Call Terms shall be given to registered holders of
Warrants in writing by the Company or the Warrant Agent.

     3.5 Optional Reduction of Warrant Price. Subject to the limits, if any,
established from time to time by the Board of Directors of the Company or in the
Warrant Agreement, the Company shall have the right, at any time or from time to
time, voluntarily to reduce the then current Warrant Price to such amount (the
"Reduced Warrant Price") and for such period or periods of time, which may be
through the close of business on the Expiration Date (the "Reduced Warrant Price
Period"), as may be deemed appropriate by the Board of Directors of the Company.
Notice of any such Reduced Warrant Price and Reduced Warrant Price Period shall
be given to registered holders of Warrants in writing by the Company or the
Warrant Agent. After the termination of the Reduced Warrant Price Period, the
Warrant Price shall be such Warrant Price that would have been in effect had
there been no reduction in the Warrant Price pursuant to the provisions of this
Section 3.5.

     3.6 Reservation of Shares. For the purpose of enabling it to satisfy any
obligation to issue Shares upon exercise of Warrants, the Company will at all
times through the close of business on the Expiration Date, reserve and keep
available, free from preemptive rights and out of its aggregate authorized but
unissued or treasury shares of [Class D Common/Preferred Stock], the number of
Shares deliverable upon the exercise of all outstanding Warrants, and the
transfer agent for the shares is hereby irrevocably authorized and directed at
all times to reserve such number of authorized and unissued or treasury shares
of [Class D Common/Preferred Stock] as shall be required for such purpose. The
Company will keep a copy of this Agreement on file with such transfer agent and
with every transfer agent for any shares of the Company's capital stock issuable
upon the exercise of Warrants. The Warrant Agent is hereby irrevocably
authorized to requisition from time to time from such transfer agent stock
certificates issuable upon exercise of outstanding Warrants, and the Company
will supply such transfer agent with duly executed stock certificates for such
purpose.

     Before taking any action that would cause an adjustment pursuant to Section
3.7 reducing the Exercise Price below the then par value (if any) of the Shares
issuable upon exercise of the Warrants, the Company will take any corporate
action that may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue fully paid and nonassessable Shares at the
Exercise Price as so adjusted.

     The Company covenants that all Shares issued upon exercise of the Warrants
will, upon issuance in accordance with the terms of this Agreement, be fully
paid and nonassessable and free from all taxes, liens, charges and security
interests created by or imposed upon the Company with respect to the issuance
and holding thereof.

     3.7 Obtaining of Governmental Approvals and Stock Exchange Listings. So
long as any Warrants remain outstanding, the Company will take all necessary
steps (a) to obtain and keep effective any and all permits, consents and
approvals of governmental agencies and authorities and to make filings under
federal and state securities acts and laws, which may be or become requisite in
connection with the issuance, sale, transfer and delivery of the Warrant
Certificates, the exercise of the Warrants and the issuance, sale, transfer and
delivery of the Shares issued upon excise of Warrants, and (b) to have the
shares of Stock immediately upon their issuance upon exercise of Warrants, (i)
listed on each national securities exchange on which the [Class D
Common/Preferred Stock] is then listed or (ii) if the [Class D Common/Preferred
Stock] is not then listed on any national securities exchange, listed for
quotation on the NASD Automated Quotations System ("Nasdaq") National Market
("Nasdaq National Market") or such other over-the-counter quotation system on
which the Stock may then be listed.

     3.8 Adjustment of Exercise Price and Number of Shares Purchasable or Number
of Warrants. The Exercise Price, the number of Shares purchasable upon the
exercise of each Warrant and the number of Warrants outstanding are subject to
adjustment from time to time upon the occurrence of the events enumerated in
this Section 3.8.

         (a) If the Company shall (i) pay a dividend on its capital stock
(including [Class D Common/Preferred Stock]) in shares of Stock, (ii) subdivide
its outstanding shares of [Class D Common/Preferred Stock], (iii) combine its
outstanding shares of [Class D Common/Preferred Stock] into smaller number of
shares of [Class D Common/Preferred

                                        4

<PAGE>

Stock] or (iv) issue any shares of its capital stock in a reclassification of
the [Class D Common/Preferred Stock] (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
corporation), the number of Shares purchasable upon exercise of each Warrant
immediately prior thereto shall be adjusted so that the holder of each Warrant
shall be entitled to receive the kind and number of Shares or other securities
of the Company which such holder would have owned or have been entitled to
receive after the happening of any of the events described above, had such
Warrant been exercised immediately prior to the happening of such event or any
record date with respect thereto. An adjustment made pursuant to this paragraph
(a) shall become effective immediately after the effective date of such event
retroactive to the record date, if any, for such event.

         (b) In the event of any capital reorganization or any reclassification
of the [Class D Common/Preferred Stock] (except as provided in paragraph (a)
above or paragraph (h) below), any holder of Warrants upon exercise thereof
shall be entitled to receive, in lieu of the [Class D Common/Preferred Stock] to
which he would have become entitled upon exercise immediately prior to such
reorganization or reclassification, the shares (of any class or classes) or
other securities or property of the Company that he or she would have been
entitled to receive at the same aggregate Exercise Price upon such
reorganization or reclassification if his or her Warrants had been exercised
immediately prior thereto; and in any such case, appropriate provision (as
determined in good faith by the Board of Directors of the Company, whose
determination shall be conclusive and shall be evidenced by a resolution filed
with the Warrant Agent) shall be made for the application of this Section 3.8
with respect to the rights and interests thereafter of the holders of Warrants
(including the allocation of the adjusted Warrant Price between or among shares
of classes of capital stock), to the end that this Section 3.8 (including the
adjustments of the number of shares of [Class D Common/Preferred Stock] or other
securities purchasable and the Warrant Price thereof) shall thereafter be
reflected, as nearly as reasonably practicable, in all subsequent exercises of
the Warrants for any shares or securities or other property thereafter
deliverable upon the exercise of the Warrants.

         (c) Except for adjustments required by paragraph (h) hereof, no
adjustment in the number of Shares purchasable hereunder shall be required
unless such adjustment would require an increase or decrease of at least one
percent (1%)in the number of Shares purchasable upon the exercise of each
Warrant; provided, however, that any adjustments which by reason of this
paragraph (c) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations shall be made to the
nearest cent and to the nearest one- hundredth of a Share, as the case may be.

         (d) Whenever the number of Shares purchasable upon the exercise of each
Warrant is adjusted as herein provided (whether or not the Company then or
thereafter elects to issue additional Warrants in substitution for an adjustment
in the number of Shares as provided in paragraph (f), the Exercise Price payable
upon exercise of each Warrant shall be adjusted by multiplying such Exercise
Price immediately prior to such adjustment by a fraction, of which the numerator
shall be the number of Shares purchasable upon the exercise of each Warrant
immediately prior to such adjustment, and of which the denominator shall be the
number of Shares so purchasable immediately thereafter.

         (e) For the purpose of this Section 3.8, the term "shares of Stock"
shall mean (i) the class of stock designated as the [Class D Common/Preferred
Stock] of the Company at the date of this Agreement, or (ii) any other class of
stock resulting from successive changes or reclassification of such shares
consisting solely of changes in par value, of from par value to no par value, or
from no par value to par value. If at any time, as a result of an adjustment
made pursuant to paragraph (a) or (b) above, the holders of Warrants shall
become entitled to purchase any shares of the Company other than shares of
Stock, thereafter the number of such other shares so purchasable upon exercise
of each Warrant and the Exercise Price of such shares shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Shares contained in paragraphs
(a) through (d), inclusive, above, and the provisions of Section 2.1, 2.2, 2.3,
3.6, 3.7(a) and 3.10, with respect to the Shares, shall apply on like terms to
any such other shares.

         (f) The Company may elect, on or after the date of any adjustment
required by paragraphs (a) through (b) of this Section 3.8, to adjust the number
of Warrants in substitution for an adjustment in the number of Shares
purchasable upon the exercise of a Warrant. Each of the Warrants outstanding
after such adjustment of the number of Warrants shall be exercisable for the
same number of shares as immediately prior to such adjustment. Each Warrant held
of record prior to such adjustment of the number of Warrants shall become that
number of Warrants (calculated to the nearest

                                        5

<PAGE>

hundredth) obtained by dividing the Warrant Price in effect prior to adjustment
of the Warrant Price by the Warrant Price in effect after adjustment of the
Warrant Price. The Company shall notify the holders of Warrants in the same
manner as provided in the first paragraph of Section 3.10, of its election to
adjust the number of Warrants, indicating the record date for the adjustment,
and, if known at the time, the amount of the adjustment to be made. This record
date may be the date on which the Exercise Price is adjusted or any day
thereafter. Upon each adjustment of the number of Warrants pursuant to this
paragraph (f) the Company shall, as promptly as practicable, cause to be
distributed to holders of record of Warrants on such record date Warrant
Certificates evidencing, subject to Section 3.9, the additional Warrants to
which such holders shall be entitled as a result of such adjustment, or, at the
option of the Company, shall cause to be distributed to such holders of record
in substitution and replacement for the Warrant Certificates held by such
holders prior to the date of adjustment, and upon surrender thereof, if required
by the Company, new Warrant Certificates evidencing all the Warrants to be
issued, executed and registered in the manner specified in Section 1.3 and
Article 4 (and which may bear, at the option of the Company, the

         adjusted Exercise Price) and shall be registered in the names of the
holders of record of Warrant Certificates on the record date specified in the
notice.

         (g) Except as provided in paragraph (a) of this Section 3.8, no
adjustment in respect of any dividends shall be made during the term of a
Warrant or upon the exercise of a Warrant.

         (h) In case of any consolidation of the Company with or merger of the
Company into another corporation or in case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, the Company or such successor or purchasing corporation, as the case
may be, shall execute with the Warrant Agent an agreement that each holder of a
Warrant shall have the right thereafter upon payment of the Warrant Price in
effect immediately prior to such action to purchase upon exercise of each
Warrant the kind and amount of shares and other securities and property which he
or she would have owned or have been entitled to receive after the happening of
such consolidation, merger, sale or conveyance had such Warrant been exercised
immediately prior to such action. The Company shall mail by first class mail,
postage prepaid, to each holder of a Warrant, notice of the execution of any
such agreement. Such agreement shall provide for adjustments, which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section 3.8. The provisions of this paragraph (h) shall similarly apply to
successive consolidations, mergers, sales or conveyances. The Warrant Agent
shall be under no duty or responsibility to determine the correctness of any
provisions contained in any provisions contained in any such agreement relating
either to the kind or amount of shares of stock or other securities or property
receivable upon exercise of Warrants or with respect to the method employed and
provided therein for any adjustments and shall be entitled to rely upon the
provisions contained in any such agreement.

         (i) Irrespective of any adjustments in the Exercise Price or the number
or kind of shares purchasable upon the exercise of the Warrants, Warrants
theretofore or thereafter issued may continue to express the same price and
number and kind of shares as are stated in the Warrants initially issuable
pursuant to this Agreement.

     3.9 Fractional Warrants and Fractional Shares.


         (a) The Company shall not be required to issue fractions of Warrants on
any distribution of Warrants to holders of Warrant Certificates or to distribute
Warrant Certificates that evidence fractional Warrants. In lieu of such
fractional Warrants, there shall be paid to the registered holder of the Warrant
Certificates with regard to which such fractional Warrants would otherwise be
issuable, an amount in cash equal to the same fraction of the current market
value of a full Warrant. For purposes of this Section, the current market value
of a Warrant shall be the closing price of one Warrant (as determined pursuant
to paragraph (c) below) for the trading day immediately prior to the date on
which such fractional Warrant would have been otherwise issuable.

         (b) Notwithstanding any adjustment pursuant to Section 3.9 in the
number of Shares purchasable upon the exercise of a Warrant, the Company shall
not be required to issue fractions of Shares upon exercise of the Warrants or to
distribute certificates which evidence fractional Shares. In lieu of fractional
Shares, there shall be paid to the registered holders of Warrant Certificates at
the time such Warrant Certificates are exercised as herein provided an amount in
cash equal to the same fraction of the current market value of a share of [Class
D Common/Preferred Stock]. For purposes of this Section 3.9, the current market
value of a share of [Class D Common/Preferred Stock] shall be the

                                        6

<PAGE>

closing price of a share of [Class D Common/Preferred Stock] (as determined
pursuant to paragraph (c) below) for the trading day immediately prior to the
date of such exercise.

         (c) The closing price for each day shall be the last sale price,
regular way, or, if no such sale takes place on such day, the average of the
closing bid and asked prices, regular way, for such day, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Warrants or Stock, as the case may be, is not listed or admitted to
trading on such exchange, as reported on the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Warrants or [Class D Common/Preferred Stock],
respectively, is listed or admitted to trading, or if the Warrants or [Class D
Common/Preferred Stock], as the case may be, is not listed or admitted to
trading on any national securities exchange, as reported on Nasdaq National
Market or, if the Warrants or Stock, as the case may be, is not listed or
admitted to trading on the Nasdaq National Market, as reported on Nasdaq.

     3.10 Notices to Warrantholders. Upon any adjustment of the number of Shares
purchasable upon exercise of each Warrant, the Warrant Price or the number of
Warrants outstanding, the Company within 20 calendar days thereafter shall (i)
cause to be filed with the Warrant Agent a certificate of a firm of independent
public accountants of recognized standing selected by the Company (who may be
the regular auditors of the Company) setting forth the Warrant Price and either
the number of Shares purchasable upon exercise of each Warrant or the additional
number of Warrants to be issued for each previously outstanding Warrant, as the

                                    ARTICLE 4
                  EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES

     4.1 Exchange and Transfer. Upon surrender at the corporate trust office of
the Warrant Agent, Warrant Certificates evidencing Warrants may be exchanged for
Warrant Certificates in other denominations evidencing such Warrants and the
transfer of Warrants may be registered in whole or in part; provided that such
other Warrant Certificates shall evidence the same aggregate number of Warrants
as the Warrant Certificates surrendered for exchange or registration of
transfer. The Warrant Agent shall keep, at its corporate trust office, books in
which it shall register Warrant Certificates and exchanges and transfers of
outstanding Warrant Certificates, upon surrender of the Warrant Certificates to
the Warrant Agent at its corporate trust office for exchange or registration of
transfer, properly completed and duly endorsed and duly signed by the registered
holder or holders thereof or by the duly appointed legal representative thereof
or by a duly authorized attorney, such signature to be guaranteed (under the
Medallion Program) by (a) a bank or trust company, (b) a broker or dealer that
is a member of the Nasdaq or (c) a member of a national securities exchange and
accompanied by appropriate instruments of registration of transfer and written
instructions for transfer, all in form satisfactory to the Company and the
Warrant Agent. No service charge shall be made for any exchange or registration
of transfer of Warrant Certificates, but the Company may require payment of a
sum sufficient to cover any stamp or other tax or other governmental charge that
may be imposed in connection with any such exchange or registration of transfer.
Whenever any Warrant Certificates are surrendered for exchange or registration
of transfer, an authorized officer of the Warrant Agent shall mutually
countersign and deliver to the person or persons entitled thereto a Warrant
Certificate or Warrant Certificate duly authorized and executed by the Company,
as so requested. The Warrant Agent shall not be required to effect any exchange
or registration of transfer that will result in the issuance of a Warrant
Certificate evidencing a fraction of a Warrant or a number of full Warrants and
a fraction of a Warrant. All Warrant Certificates issued upon any exchange or
registration of transfer of Warrant Certificates shall be the valid obligations
of the Company, evidencing the same obligations and entitled to the same
benefits under this Agreement as the Warrant Certificates surrendered for such
exchange or registration of transfer.

     4.2 Treatment of Holders of Warrant Certificates. Every holder of a Warrant
Certificate, by accepting the same, consents and agrees with the Company, the
Warrant Agent and with every subsequent holder of such Warrant Certificate that,
until the transfer of the Warrant Certificate is registered on the books of the
Warrant Agent, the Company and the Warrant Agent may treat the registered holder
as the absolute owner thereof for any purpose and as the person entitled to
exercise the rights represented by the Warrants evidenced thereby, any notice to
the contrary notwithstanding.

     4.3 Cancellation of Warrant Certificates. Any Warrant Certificate
surrendered for exercise, registration of transfer or exchange shall, if
surrendered to the Company, be delivered to the Warrant Agent, and all Warrant
Certificates surrendered or so delivered to the Warrant Agent shall be promptly
canceled by the Warrant Agent and shall not be reissued and, except as expressly
permitted by this Agreement, no Warrant Certificate shall be issued hereunder in
lieu thereof. The Warrant Agent shall deliver to the Company from time to time,
or otherwise dispose of, canceled Warrant Certificates in manner satisfactory to
the Company.

                                    ARTICLE 5
                          CONCERNING THE WARRANT AGENT

     5.1 Warrant Agent. The Company hereby appoints the Warrant Agent as the
Warrant Agent of the Company in respect of the Warrant Certificates upon the
terms and subject to the conditions herein set forth, and the Warrant Agent
hereby accepts such appointment. The Warrant Agent shall have the powers and
authority granted to and conferred upon it in the Warrant Certificates and by
this Agreement, and such further powers and authority to act on behalf of the
Company as the Company may hereafter grant to or confer upon it. All of the
terms and provisions with respect to such

                                        8

<PAGE>

powers and authority contained in the Warrant Certificates are subject to and
governed by the terms and provisions hereof.

hereunder of the holders from time to time of the Warrant Certificates shall be
subject):

         (a) Performance by the Company. The Company agrees that it will take
any corporate action that may be reasonably necessary in order to fulfill its
obligations under this Agreement, and the Warrant Certificates, and that it will
not take any action that would impair its ability to perform its obligations
under this Agreement and the Warrant Certificates.

         (b) Compensation and Indemnification. The Company agrees promptly to
pay the Warrant Agent the compensation to be agreed upon with the Company for
all services rendered by the Warrant Agent and to reimburse the Warrant Agent
for reasonable out-of-pocket expenses (including reasonable counsel fees)
incurred by the Warrant Agent in connection with the services rendered hereunder
by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent,
and to hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on the part of the Warrant Agent, arising out of or in
connection with its acting as the Warrant Agent hereunder, as well as the costs
and expenses of defending against any claim of liability in the premises.

         (c) Agent for the Company. In acting under this Warrant Agreement and
in connection with the Warrant Certificates, the Warrant Agent is acting solely
as an agent of the Company, and the Warrant Agent does not assume any obligation
or relationship of agency or trust for or with any of the owners or holders of
the Warrant Certificates.

         (d) Counsel. The Warrant Agent may consult with counsel satisfactory to
it, and the opinion of such counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with the opinion of such counsel.

         (e) Documents. The Warrant Agent shall be protected and shall incur no
liability for or in respect of any action taken or thing suffered by it in
reliance upon any Warrant Certificate, notice, direction, consent, certificate,
affidavit, statement or other paper or document reasonably believed by it to be
genuine and to have been presented or signed by the proper parties.

         (f) Certain Transactions. The Warrant Agent and its officers, directors
and employees may buy, sell or deal in any of the Shares or other securities of
the Company and may become the owner of, or acquire any interest in, any Warrant
Certificates, with the same rights that it or they would have if it were not the
Warrant Agent hereunder, and, to the extent permitted by applicable law, they
may engage or be interested in any financial or other transaction with the
Company and may act on, or as depositary, trustee or agent for, any committee or
body of holders of the Shares or other obligations of the Company as freely as
if it were not the Warrant Agent.

         (g) No Liability for Interest. Except as set forth in the Warrant
Agreement, the Warrant Agent shall not be under any liability for interest on
any moneys or other consideration at any time received by it pursuant to any of
the provisions of this Agreement or of the Warrant Certificates.

         (h) No Liability for Invalidity. The Warrant Agent shall not incur any
liability with respect to the validity of this Agreement or any of the Warrant
Certificates.

         (i) No Responsibility for Representations. The Warrant Agent shall not
be responsible for any of the recitals or representations contained herein or in
the Warrant Certificates (except the Warrant Agent shall be responsible for any
representations of the Warrant Agent herein and for its countersignature on the
Warrant Certificates), all of which are made solely by the Company.

         (j) No Implied Obligations. The Warrant Agent shall be obligated to
perform such duties as are herein and in the Warrant Certificates specifically
set forth, but no implied duties or obligations shall be read into this
Agreement

                                        9

<PAGE>

or the Warrant Certificates against the Warrant Agent. The Warrant Agent shall
not be under any obligation to take any action hereunder which may tend to
involve it in any expense or liability, the payment of which within a reasonable
time is not, in its reasonable opinion, assured to it. The Warrant Agent shall
not be accountable or under any duty or responsibility for the use by the
Company of any of the Warrant Certificates authenticated by the Warrant Agent
and delivered by it to the Company pursuant to this Agreement or for the
application or by the Company of the proceeds of the Warrant Certificates. The
Warrant Agent shall have not duty or responsibility in case of any default by
the Company in the performance of its covenants or agreements contained in the
Warrant Certificates or in the case of the receipt of any written demand from a
holder or a Warrant Certificate with respect to such default, including any duty
or responsibility to initiate or attempt to initiate any proceedings at law or
otherwise or to make any demands upon the Company.

         (k) Instructions. The Warrant Agent is hereby authorized and directed
to accept instructions with respect to the performance of its duties hereunder
from the Chairperson of the Board, the Chief Executive Officer, the President,
any Vice President, the Treasurer, the Secretary or any Assistant Secretary of
the Company, and to apply to such officers for advice or instructions in
connection with its duties, and shall not be liable for any action taken or
suffered to be taken by it in good faith in accordance with instructions of any
such officer or in good faith reliance upon any statement signed by any one of
such officers of the Company with respect to any fact or matter (unless other
evidence in respect thereof is herein specifically prescribed) which may be
deemed to be conclusively proved and established by such signed statement.

     5.3  Registration and Appointment of Successor Warrant Agent.


         (a) The Company agrees, for the benefit of the holders from time to
time of the Warrant Certificates, that at all times there shall be a Warrant
Agent hereunder until all the Warrant Certificates are no longer exercisable.

         (b) The Warrant Agent may at any time resign as such agent by giving
written notice to the Company of such intention on its part, specifying the date
on which its desired resignation shall become effective; provided that such date
shall not be less than 60 days after the date on which such notice is given
unless the Company agrees to accept less notice. The Warrant Agent may be
removed at any time by the filing with it of an instrument in writing signed by
or on behalf of the Company and specifying such removal and the date when it
shall become effective. Such resignation or removal shall take effect upon the
appointment by the Company, as hereinafter provided, of a successor Warrant
Agent (which shall be a bank or trust company organized and doing business under
the laws of the United States of America or of any State, in good standing, and
authorized under such laws to exercise corporate trust powers) and the
acceptance of such appointment by such successor Warrant Agent. Upon its
resignation or removal, the Warrant Agent shall be entitled to the payment by
the Company of the compensation agreed to under Section 5.2(b) hereof for, and
to the reimbursement of all reasonable out-of-pocket expenses incurred in
connection with, the services rendered hereunder by the Warrant Agent.

         (c) If at any time the Warrant Agent shall resign, or shall be removed,
or shall become incapable of acting, or shall be adjudged bankrupt or insolvent,
or shall file a petition seeking relief under the Federal Bankruptcy Code, as
now constituted or hereafter amended, or under any other applicable federal or
state bankruptcy law or similar law or make an assignment for the benefit of its
creditors or consent to the appointment of a receiver or custodian of all or any
substantial part of its property, or shall admit in writing its inability to pay
or meet its debts as they mature, or if a receiver or custodian of it or of all
or any substantial part of its property shall be appointed, or if an order of
any court shall be entered for relief against it under the Federal Bankruptcy
Code, as now constituted or hereafter amended, or under any other applicable
federal or state bankruptcy or similar law or if any public officer shall have
taken charge or control of the Warrant Agent or of its property or affairs, for
the purpose of rehabilitation, conservation or liquidation, a successor Warrant
Agent, qualified in accordance with the terms of this Agreement, shall be
appointed by the Company by an instrument in writing, filed with the successor
Warrant Agent. Upon the appointment of a successor Warrant Agent and acceptance
by the latter of such appointment, the Warrant Agent so superseded shall cease
to be the Warrant Agent hereunder.

         (d) Any successor Warrant Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor and to the Company an instrument
accepting such appointment hereunder, and thereupon such successor

                                       10

with all the authority, rights, powers, trusts, immunities, duties and
obligations of such predecessor with like effect as if originally named as
Warrant Agent hereunder, and such predecessor, upon payment of its charges and
disbursements then unpaid, shall thereupon become obligated to transfer, deliver
and pay over, and such successor Warrant Agent shall be entitled to receive, all
moneys, securities and other property on deposit with or held by such
predecessor, as Warrant Agent hereunder.

merged or converted or any corporation with which the Warrant Agent may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Warrant Agent shall be a party, or any corporation to
which the Warrant agent shall sell or otherwise transfer all or substantially
