                   8 7/8% Senior Subordinated Notes due 2011

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. Interest. Radio One, Inc., a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Note at 8 7/8% per
annum from May 18, 2001 until maturity and to pay the Liquidated Damages payable
pursuant to Section 5 of the Registration Rights Agreement referred to below.
The Company will pay interest and Liquidated Damages semi-annually in arrears on
January 1 and July 1 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each an "Interest Payment Date"). Interest on
the Notes will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the date of issuance; provided that if
there is no existing Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be January 1, 2002. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at a rate that is 1%
per annum in excess of the rate then in effect; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest and Liquidated Damages (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

     2. Method of Payment. The Company will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the January 1 or July 1 next
preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and Liquidated Damages, if any, and interest
at the office or agency of the Company maintained for such purpose within or
without the City and State of New York, or, at the option of the Company,
payment of interest and Liquidated Damages may be made by check mailed to the
Holders at their addresses set forth in the register of Holders, and provided
that payment by wire transfer of immediately available funds will be required
with respect to principal of and interest, premium and Liquidated Damages on,
all Global Notes and all other Notes the Holders of which shall have provided
wire transfer instructions to the Company or the Paying Agent. Such payment
shall be in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts.

     3. Paying Agent and Registrar. Initially, United States Trust Company of
New York, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

     4. Indenture. The Company issued the Notes under an Indenture dated as of
May 18, 2001 ("Indenture") among the Company, the guarantors party thereto (the
"Guarantors") and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb). The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are obligations of the
Company limited to $300.0 million in aggregate principal amount, plus amounts,
if any, issued to pay Liquidated Damages on outstanding Notes as set forth in
Paragraph 2 hereof.

    2009 and thereafter.................................         100.000%
</TABLE>

     (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5,
at any time prior to July 1, 2004, the Company may redeem Notes with the net
proceeds of one or more Equity Offerings at a redemption price equal to 108.875%
of the aggregate principal amount thereof; provided that at least 65% in
aggregate principal amount of the Notes originally issued remain outstanding
immediately after the occurrence of such redemption and that such redemption
occurs within 180 days of the date of the closing of such Equity Offering.

     6. Mandatory Redemption.

     Except as set forth in paragraph 7 below, the Company shall not be required
to make mandatory redemption payments with respect to the Notes.

     7. Repurchase at Option Holder.

     (a) If there is a Change of Control, the Company shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within 60 days following any Change of
Control, the Company shall mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture.

     (b) If the Company or a Subsidiary consummates any Asset Sales, within five
days of each date on which the aggregate amount of Excess Proceeds exceeds $10.0
million, the Company shall commence an offer to all Holders of Notes (as "Asset
Sale Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum
principal amount of Notes (including any Additional Notes) that may be purchased
out of the Excess Proceeds at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest and Liquidated
Damages thereon, if any, to the date fixed for the closing of such offer, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Notes (including any Additional Notes) tendered pursuant
to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such
Subsidiary) may use such deficiency for general corporate purposes. If the
aggregate principal amount of Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on
a pro rata basis. Holders of Notes that are the subject of an offer to purchase
will receive an Asset Sale Offer from the Company prior to any related purchase
date and may elect to have such
<PAGE>

Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Notes.

     8.  Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions thereof
called for redemption.

     9.  Denominations, Transfer, Exchange.  The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided
in the Indenture.  The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture.  The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part.  Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated
as its owner for all purposes, subject to the provisions of the Notes for record
dates.

     11. Amendment, Supplement and Waiver.  Subject to certain exceptions, the
Indenture, the Subsidiary Guarantees or the Notes may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of
the then outstanding Notes and Additional Notes, if any, voting as a single
class, and any existing default or compliance with any provision of the
Indenture, the Subsidiary Guarantees or the Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Notes
and Additional Notes, if any, voting as a single class.  Without the consent of
any Holder of a Note, the Indenture, the Subsidiary Guarantees or the Notes may
be amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's or Guarantor's obligations
to Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any
such Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act, to
provide for the Issuance of Additional Notes in accordance with the limitations
set forth in the Indenture, or to allow any Guarantor to execute a supplemental
indenture to the Indenture and/or a Subsidiary Guarantee with respect to the
Notes.

     12. Defaults and Remedies.  Events of Default include: (i) default for 30
days in the payment when due of interest or Liquidated Damages on the Notes;
(ii) default in payment when due of principal of or premium, if any, on the
Notes when the same becomes due and payable at maturity, upon redemption
(including in connection with an offer to purchase) or otherwise, (iii) failure
by the Company to comply with Section 4.15 of the Indenture; (iv) failure by the
Company for 30 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Notes (including Additional Notes, if
any) then outstanding voting as a single class to comply with Section 4.07, 4.09
or 4.10 or 5.01 of the Indenture; (v) failure by the Company for 60 days after
notice to the Company by the Trustee or the Holders of at least 25% in principal
amount of the Notes (including Additional Notes, if any) then outstanding voting
as a single class to comply with certain other agreements in the Indenture, the
Notes; (vi) default under certain other agreements relating to Indebtedness of
the Company which default is caused by a failure to pay principal of such
Indebtedness at the final maturity thereof or results
<PAGE>

in the acceleration of such Indebtedness prior to its express maturity; (vii)
certain final judgments for the payment of money that remain undischarged for a
period of 60 days; (viii) certain events of bankruptcy or insolvency with
respect to the Company or any of its Significant Subsidiaries; and (ix) except
as permitted by the Indenture, any Subsidiary Guarantee of a Significant
Subsidiary shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Guarantor that is a Significant Subsidiary or any Person acting on its behalf
shall deny or disaffirm its obligations under such Guarantor's Subsidiary
Guarantee. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Notes will become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

     13. Trustee Dealings with Company.  The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

     14. No Recourse Against Others. A director, officer, employee, incorporator
or stockholder, of the Company, as such, shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

     15. Authentication. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

     16. Abbreviations.  Customary abbreviations may be used in the name of a
Holder or an assignee, such as:  TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).

     17. Additional Rights of Holders of Restricted Global Notes and Restricted
Definitive Notes.  In addition to the rights provided to Holders of Notes under
the Indenture, Holders of Restricted Global Notes and Restricted Definitive
Notes shall have all the rights set forth in the Registration Rights Agreement
dated as of May 18, 2001, among the Company, the Guarantors and the other
parties named on the signature pages thereof or, in the case of Additional
Notes, Holders of Restricted Global Notes and Restricted Definitive Notes shall
have the rights set forth in one or more registration rights agreements, if any,
between the Company and the other parties thereto, relating to rights given by
the Company to the purchasers of any Additional Notes (collectively, the
"Registration Rights Agreement").
<PAGE>

     18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     19. Governing Law.  THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN
AND BE USED TO CONSTRUE THE NOTES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES
OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY.

     20. Submission to Jurisdiction; Service of Process; Waiver of Jury Trial.
Each party hereto hereby submits to the nonexclusive jurisdiction of the United
States District Court for the Southern District of New York and of any New York
State Court sitting in New York City for purposes of all legal proceedings
arising out of or relating to the Notes or the transactions contemplated hereby.
Each party hereto irrevocably waives, to the fullest extent permitted by law,
any objection which it may now or hereafter have to the laying of the venue of
any such proceeding brought in such a court and any claim that any such
proceeding brought in such a court has been brought in an inconvenient forum.
Process in any such suit, action or proceeding may be served on any party
anywhere in the world, whether within or without the State of New York.  Without
limiting the foregoing, the parties agree that service of process upon such
party at the address referred to in Section 13.02 of the Indenture, together
with written notice of such service to such party, shall be deemed effective
service of process upon such party.  Each of the parties hereto irrevocably
waives any and all rights to trial by jury in any legal proceeding arising out
