Stockholder is  Incapacitated,  the other Principal  Stockholder  shall have the
right,  in addition to the other rights  granted  pursuant to this Section 2, to
vote, or cause to be voted, all voting securities of the Company

                                       6



over which such  Incapacitated  Principal  Stockholder  would otherwise have the
power to vote or direct the voting,  as to all matters  presented  for a vote of
the Company's stockholders.

                  (g)  REGULATORY  SAVINGS   PROVISION.   If  at  any  time  the
possession by a Principal  Stockholder  of the voting power  represented  by the
voting  securities  held by such  Principal  Stockholder,  or  over  which  such
Principal  Stockholder has the power to vote or direct the voting,  differs from
the voting power required or permitted to be held by such Principal Stockholder,
or requires a consent or waiver that at such time has not been  obtained,  under
any Law  applicable to such Principal  Stockholder  or the Company,  then (i) if
such voting  power  exceeds the amount  permitted  to be held by such  Principal
Stockholder,  or with  respect  to  which  such a  consent  or  waiver  has been
obtained,  the other Principal Stockholder shall have the sole power to vote, or
cause to be voted, the number of voting  securities of the Company  representing
such excess voting power and over which the first  Principal  Stockholder  would
otherwise  have the  power  to vote or  direct  the  voting,  as to all  matters
presented  for a vote of the  Company's  stockholders,  and (ii) if such  voting
power is less than the amount required to be held by such Principal Stockholder,
such  Principal  Stockholder  shall have the sole power to vote,  or cause to be
voted,  as to all matters  presented for a vote of the  Company's  stockholders,
that  number,  and  only  that  number  of  voting  securities  of  the  Company
representing  sufficient voting power to eliminate such shortfall and over which
the other Principal Stockholder would otherwise have the power to vote or direct
the voting.  In all cases,  the provisions of this Section 4(g) shall be applied
only  to the  extent  and  for the  period  necessary  to  bring  the  Principal
Stockholders  and the Company into compliance with applicable Law, and shall not
operate to cause  either  Principal  Stockholder  not to be in  compliance  with
applicable  Law. In the exercise of voting rights provided by this Section 4(g),
each Principal  Stockholder shall remain subject to the other provisions of this
Agreement.

                  SECTION 3 DISPOSITION OF INCAPACITATED PRINCIPAL STOCKHOLDER'S
SHARES.

                  In the event that a Principal  Stockholder  is  Incapacitated,
the other Principal  Stockholder  shall have the right to direct the disposition
of all  Stockholder  Shares  held by the  Incapacitated  Principal  Stockholder,
including,  without  limitation,  the right to purchase such Stockholder Shares;
provided, however, that any Transfer of any such Stockholder Shares shall be for
a consideration equal to the Fair Market Value of such Stockholder Shares.

                  SECTION 4 RESTRICTIONS ON TRANSFER.

                  (a) RESTRICTIONS ON TRANSFER.  No Stockholder may Transfer any
Stockholder  Shares,  except (i) in a  Permitted  Transfer  or (ii) to any other
Person, subject to the provisions of Section 4(c), if applicable.

                  (b) CERTAIN PERMITTED TRANSFERS.  Section 4(a) shall not apply
to Transfers  ("PERMITTED  TRANSFERS") of Stockholder  Shares (i) to a Permitted
Transferee of a Principal  Stockholder;  provided  that, in connection  with any
such  Transfer,  each  such  Permitted  Transferee  not  already a party to this
Agreement executes a Joinder Agreement substantially in the form attached hereto
as Exhibit A and thereby becomes a party to this Agreement,  or (ii) pursuant to
Sections 3, 6, 7 or 8. Notwithstanding the provisions of clause (i) of the first
sentence of this Section 4(b), neither of the Principal Stockholders shall sell,
assign or otherwise  transfer any interest in any

                                       7



shares of Class B Common Stock to the spouse or former spouse of such  Principal
Stockholder, or to any parent or grandparent or any lineal descendant (including
any adopted child) of any parent or grandparent of such Principal  Stockholder's
spouse  or  former  spouse  (unless  such  lineal  descendant  is also a  lineal
descendant  (including  any  adopted  child)  of  such  Principal  Stockholder),
including by gift, will, intestate succession or other operation of law, unless,
as a condition  of such  transfer  (a) such  Principal  Stockholder  retains all
voting power with respect to such Class B Common Stock so long as such Principal
Stockholder is living, and (b) the estate of such Principal Stockholder,  in the
case of the  death  of the  Principal  Stockholder,  or the  transferee  of such
interest  agrees (I) not to exercise any voting power with respect to such Class
B Common Stock and (II) to cause such Class B Common Stock to be converted  into
shares of single vote or  non-voting  Common Stock of the Company upon the death
of such Principal Stockholder.

                  (c) RIGHT OF FIRST REFUSAL.  Notwithstanding the provisions of
Section 4(a), a Stockholder  may Transfer shares of Class C Common Stock so long
as at least ninety (90) days prior to making any such Transfer, such Stockholder
delivers a written  notice  (the  "TRANSFER  NOTICE")  to each of the  Principal
Stockholders.  The  Transfer  Notice  will  disclose  in  reasonable  detail the
identity of the  prospective  transferee(s)  and the terms and conditions of the
proposed Transfer. Such Stockholder shall not consummate any such Transfer until
thirty (30) days after the Transfer  Notice has been  delivered to the Principal
Stockholders (the "AUTHORIZATION DATE"). The Principal Stockholders may elect to
purchase any or all of the shares of Class C Common Stock to be transferred upon
the same terms and  conditions  as those set forth in the  Transfer  Notice,  by
delivering a written notice of such election to such  Stockholder  within thirty
(30)  days  after  the  receipt  of  the  Transfer   Notice  by  the   Principal
Stockholders.  If the  aggregate  number of shares of Class C Common Stock which
the Principal  Stockholders  have elected to purchase is greater than the number
of shares of Class C Common Stock  specified in the Transfer  Notice,  then each
Principal Stockholder will be entitled to purchase the number of shares of Class
C Common Stock equal to the product of (i) the quotient  determined  by dividing
the number of shares of Class C Common  Stock  elected to be  purchased  by such
Principal  Stockholder by the aggregate number of shares of Class C Common Stock
elected to be purchased by both Principal  Stockholders,  multiplied by (ii) the
number of shares of Class C Common Stock  specified in the Transfer  Notice.  If
the  Principal  Stockholders  have not elected to purchase  all of the shares of
Class C Common Stock  specified in the Transfer  Notice,  such  Stockholder  may
Transfer  the  remaining  shares  of  Class C Common  Stock  to the  prospective
transferee(s)  as specified in the Transfer  Notice,  at a price and on terms no
more  favorable  to the  transferee(s)  thereof  than  specified in the Transfer
Notice,  during the 90-day period immediately  following the Authorization Date.
Any shares of Class C Common Stock not so transferred  within such 90-day period
must  be  reoffered  to  the  Principal  Stockholders  in  accordance  with  the
provisions of this Section 4(c).

                  (d) OPINION OF COUNSEL.  No holder of  Stockholder  Shares may
Transfer  any such stock  (other  than  pursuant  to an  effective  registration
statement under the Securities Act) without first delivering to the Company,  if
the Company so requests, an opinion of counsel reasonably acceptable in form and
substance  to the Company  that  registration  under the  Securities  Act is not
required in connection with such transfer.

                  SECTION 5 LEGENDS.

                                       8



                  (a)   STOCKHOLDERS    AGREEMENT   LEGEND.   The   certificates
representing Stockholder Shares shall bear the following legend:

         THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  ARE  SUBJECT  TO A
         STOCKHOLDERS  AGREEMENT DATED AS OF March 2, 1999 AMONG RADIO ONE, INC.
         AND  CERTAIN  STOCKHOLDERS  THEREOF,  A COPY OF WHICH  MAY BE  OBTAINED
         WITHOUT CHARGE BY THE HOLDER HEREOF AT THE PRINCIPAL  PLACE OF BUSINESS
         OF RADIO ONE, INC.  DISPOSITION  OF THIS  CERTIFICATE OR THE SECURITIES
         REPRESENTED  HEREBY OR ANY RIGHTS OR INTERESTS  THEREIN IN VIOLATION OF
         SUCH STOCKHOLDERS AGREEMENT SHALL BE NULL AND VOID.

                  SECTION 6 SALE OF THE COMPANY.  If the Principal  Stockholders
mutually  approve a Company  Sale (an  "APPROVED  SALE"),  the other  holders of
Stockholder  Shares (the  "OTHER  STOCKHOLDERS")  shall  consent to and raise no
objections  against such  Approved Sale (and shall waive any rights of appraisal
arising in connection  therewith)  and shall fully  cooperate  with and take all
necessary and  desirable  actions in connection  with the  consummation  of such
Approved Sale,  including  without  limitation (a) executing a purchase and sale
agreement  and any other  agreement  reasonably  necessary  to  effectuate  such
Approved Sale in the form to be entered into by the Principal Stockholders,  (b)
amending the Company's Certificate of Incorporation,  (c) merging,  combining or
consolidating   the   Company   with  any  other   Person,   (d)   reorganizing,
recapitalizing,   liquidating,   dissolving  or  winding-up  the  Company,   (e)
exchanging  or  splitting  stock  of the  Company  or (f)  selling,  leasing  or
exchanging  all or  substantially  all of the property and assets of the Company
and its subsidiaries on a consolidated basis. If the Approved Sale is structured
as a sale of stock,  the  Other  Stockholders  shall  agree to sell all of their
shares of Common Stock and rights to acquire shares of Common Stock on the terms
and  conditions  approved  by the  Board  and the  Principal  Stockholders.  The
obligations  of the Other  Stockholders  with respect to any  Approved  Sale are
subject to the conditions that (a) upon the  consummation of such Approved Sale,
all of the  holders  of Common  Stock will  receive  the same form and amount of
consideration  per share of Common Stock,  or if any holders are given an option
as to the form and amount of consideration  to be received,  all holders will be
given  the  same  option  and (b) no  stockholder  shall  be  required  to incur
indemnification  obligations (whether several or joint and several) which are in
excess of the net proceeds  received by such Stockholder in connection with such
Approved Sale. In the event that a Principal  Stockholder is Incapacitated,  any
Company  Sale  that  is  approved  by  the  Principal  Stockholder  that  is not
Incapacitated  shall be deemed to be an Approved  Sale for all purposes  hereof,
and all  references to the Principal  Stockholders  in this  paragraph  shall be
deemed to exclude the Incapacitated Principal Stockholder.

                  SECTION 7 PARTICIPATION RIGHTS. Not less than twenty (20) days
prior to any proposed Transfer of Stockholder Shares by a Principal  Stockholder
(the "SELLING PRINCIPAL  STOCKHOLDER"),  the Selling Principal Stockholder shall
deliver to the other  Principal  Stockholder  (so long as such  other  Principal
Stockholder  is  not   Incapacitated)  a  written  notice  (the  "SALE  NOTICE")
specifying in reasonable  detail the identity of the proposed  transferee(s) and
the terms and  conditions  of the  proposed  Transfer.  Provided  that the other
Principal  Stockholder is not  Incapacitated and has not elected to exercise the
right of first  refusal  provided in Section  4(c) with  respect to the Transfer
specified  in the Sale Notice,  such other  Principal  Stockholder  may elect to
participate  in the proposed

                                       9



Transfer by delivering to the Selling Principal  Stockholder a written notice of
such election within the 10-day period following delivery of the Sale Notice. If
the other  Principal  Stockholder  elects to participate  in such Transfer,  the
Selling  Principal  Stockholder  and such other  Principal  Stockholder  will be
entitled to sell in such  proposed  Transfer,  at the same price and on the same
terms,  a number of shares of each class of Common  Stock  specified in the Sale
Notice  equal to the product of (i) the  quotient  determined  by  dividing  the
number  of  shares  of such  class of  Common  Stock  then  held by the  Selling
Principal Stockholder or such other Principal  Stockholder,  as the case may be,
by the aggregate number of shares of such class of Common Stock then held by the
Selling Principal Stockholder and such other Principal  Stockholder,  multiplied
by (ii) the  number of shares of such  class of Common  Stock to be sold in such
proposed  Transfer.  For  purposes of this Section 7, the amount of Common Stock
held by a Principal  Stockholder shall be deemed to include all shares of Common
Stock  acquirable  pursuant to the exercise of Vested  Options then held by such
Principal Stockholder.  Notwithstanding the foregoing,  this Section 7 shall not
apply to (i)  Transfers  pursuant to Rule 144 under the  Securities  Act (or any
successor  provision),  (ii)  Transfers  pursuant to Section 4, or (v) Transfers
pursuant to Section 6.

                  SECTION 8 DEADLOCKS.

                  (a) DEFINITION.  For purposes  hereof,  a "DEADLOCK"  shall be
deemed to have  occurred if,  after having tried on a good-faith  basis to do so
for a period  of at least  ninety  (90) days  after  delivery  by one  Principal
Stockholder to the other  Principal  Stockholder of a written notice  requesting
the  commencement  of such good faith efforts,  the Principal  Stockholders  are
unable to reach mutual  agreement  with respect to either (i) the  individual or
individuals  to fill  one or more of the  Board  seats to be  filled  by Class B
Directors,  other than Hughes or Liggins, or (ii) a Company Sale proposed by one
of the Principal Stockholders.

                  (b) INITIATION OF AUCTION.  Upon the occurrence of a Deadlock,
either  Principal  Stockholder  may, by written  notice  delivered  to the other
Principal  Stockholder,  initiate a bidding process to determine which Principal
Stockholder shall acquire all of the other Principal  Stockholder's  Stockholder
Shares.  Such  bidding  process  shall begin on the date (the  "INITIAL  AUCTION
DATE") mutually agreed to by the Principal Stockholders, which date shall be not
later than  thirty  (30) days after  delivery  of the notice  referred to in the
preceding  sentence.  Such bidding  process  shall in all events  proceed in two
stages: first, the Principal Stockholders shall determine a market valuation for
the corporation,  taken as a whole,  through the competitive  bidding procedures
described in paragraph (c) below and second,  the purchase price for the winning
bidder to  purchase  all of the  losing  bidder's  Stockholder  Shares  shall be
determined based on the formula set forth in paragraph (d) below.

                  (c) AUCTION  PROCEDURE.  On the  Initial  Auction  Date,  each
Principal   Stockholder   shall  initiate  the  bidding  process  by  delivering
simultaneously to the other Principal  Stockholder a written offer (the "INITIAL
OFFER")  which sets forth its valuation of the  outstanding  Common Stock of the
Company,  taken as a whole.  The higher of the valuations  shall  constitute the
initial bid. Such initial bid and each subsequent valuation must be met in turn,
within forty-eight (48) hours following  delivery thereof,  by either acceptance
or delivery of a written  counteroffer.  Each counteroffer after the initial bid
must be in a minimum  amount  equal to the lesser of (a) the amount that is five
percent (5%) higher than the preceding  bid (on a percentage  basis) and (b) the
amount

                                       10



that is $10,000.00  higher than the preceding bid. Any failure to respond within
forty-eight (48) hours of delivery of a bid as provided above shall be deemed to
constitute an irrevocable and unconditional acceptance of that bid. This bidding
process  shall  continue  until  one  Principal  Stockholder  accepts  the other
Principal Stockholder's latest valuation,  either affirmatively or by failing to
make a counteroffer (such final valuation, the "FINAL AUCTION PRICE").

                  (d)  DETERMINATION OF FINAL PURCHASE PRICE. The final purchase
price (the "FINAL PURCHASE  PRICE") payable by the winning bidder for all of the
losing bidder's  Stockholder  Shares shall be the amount equal to the product of
(x) the Final Auction Price and (y) the  percentage  of the  outstanding  Common
Stock of the Company  represented by the  Stockholder  Shares held by the losing
bidder.

                  (e)  CONSUMMATION OF SALE AND TRANSFER.  The sale and transfer
of the  losing  bidder's  Stockholder  Shares  to the  winning  bidder  shall be
consummated as soon as practicable  after the determination of the Final Auction
Price,  subject to receipt of necessary  governmental,  regulatory and antitrust
approvals. Each Principal Stockholder shall cooperate with the other to take all
actions necessary to conclude the sale and transfer contemplated hereunder.

                  SECTION 9.  TRANSFERS IN VIOLATION OF AGREEMENT.  Any Transfer
or attempted  Transfer of any Stockholder  Shares in violation of this Agreement
shall be void, and the Company shall not be obligated to record such Transfer on
its books or treat any purported  transferee of such  Stockholder  Shares as the
owner of such shares for any purpose.

                  SECTION 10. AMENDMENT AND WAIVER. Except as otherwise provided
herein,  no amendment  or waiver of any  provision  of this  Agreement  shall be
effective  against the Stockholders  unless such amendment or waiver is approved
in writing by the Principal Stockholders other than any Incapacitated  Principal
Stockholder. The failure of any party to enforce any provision of this Agreement
shall not be  construed as a waiver of such  provision  and shall not affect the
right of such party  thereafter to enforce each  provision of this  Agreement in
accordance with its terms.

                  SECTION 11.  SEVERABILITY.  If any provision of this Agreement
is held to be  invalid,  illegal  or  unenforceable  in any  respect  under  any
applicable  law or rule in any  jurisdiction,  such  invalidity,  illegality  or
unenforceability shall not affect any other provision or any other jurisdiction,
but  this  Agreement   shall  be  reformed,   construed  and  enforced  in  such
jurisdiction as if such invalid,  illegal or  unenforceable  provision had never
been contained herein.

                  SECTION 12. ENTIRE  AGREEMENT.  Except as otherwise  expressly
set  forth   herein,   this  document   embodies  the  complete   agreement  and
understanding among the parties hereto with respect to the subject matter hereof
and   supersedes   and  preempts  any  prior   understandings,   agreements   or
representations by or among the parties, written or oral, which may have related
to the subject matter hereof in any way.

                  SECTION 13. SUCCESSORS AND ASSIGNS;  THIRD PARTY  BENEFICIARY.
This Agreement  shall bind and inure to the benefit of and be enforceable by the
Stockholders  and their respective  permitted

                                       11



successors  and  assigns  so long  as such  Stockholders  and  their  respective
permitted  successors and assigns hold  Stockholder  Shares.  The Company is and
shall be an intended third party beneficiary of this Agreement.

                  SECTION 14.  COUNTERPARTS.  This  Agreement may be executed in
separate  counterparts each of which shall be an original and all of which taken
together shall constitute one and the same agreement.

                  SECTION 15. REMEDIES.  The Company and the Stockholders  shall
be entitled to enforce their rights under this Agreement specifically to recover
damages  by  reason of any  breach of any  provision  of this  Agreement  and to
exercise all other rights existing in their favor.  The parties hereto agree and
acknowledge  that money damages may not be an adequate  remedy for any breach of
the provisions of this Agreement and that the Company or any  Stockholder may in
its  sole  discretion  apply  to  any  court  of  law  or  equity  of  competent
jurisdiction for specific  performance and/or injunctive relief (without posting
a bond or other  security)  in order to enforce or prevent any  violation of the
provisions of this Agreement.

                  SECTION 16. NOTICES. Any notice provided for in this Agreement
shall be in  writing  and  shall be  either  personally  delivered,  or sent via
facsimile,  or mailed  first class mail  (postage  prepaid) or sent by reputable
overnight  courier service  (charges  prepaid) to the Principal  Stockholders at
their  respective  addresses set forth in the preface to this Agreement,  and to
any subsequent  holder of  Stockholder  Shares subject to this Agreement at such
address as  indicated  by the  Company's  records,  or at such address or to the
attention of such other  Person as the  recipient  party has  specified by prior
written notice to the sending  party.  Notices will be deemed to have been given
hereunder  when  delivered  personally  or sent via facsimile  (against  receipt
therefor),  three days after  deposit in the U.S. mail and one day after deposit
with a reputable overnight courier service.

                  SECTION 17. GOVERNING LAW. The corporate law of Delaware shall
govern  all  issues  concerning  the  relative  rights  of the  Company  and its
stockholders.  All other  questions  concerning the  construction,  validity and
interpretation  of this Agreement shall be governed by the internal law, and not
the law of conflicts, of Maryland.

                  SECTION 18. DESCRIPTIVE HEADINGS.  The descriptive headings of
this Agreement are inserted for convenience only and do not constitute a part of
this Agreement.

                  SECTION 19.  TERMINATION.  Notwithstanding  anything herein to
the contrary, this Agreement shall terminate upon a Company Sale.

                                       12



                  IN  WITNESS   WHEREOF,   the  parties   have   executed   this
