EXHIBIT 10.45(b)

                            TIME BROKERAGE AGREEMENT

         This  Agreement  is made  this  6th day of May,  1999,  by and  between
Sinclair Telecable, Inc., an Indiana corporation, and Commonwealth Broadcasting,
L.L.C.,  a  Virginia  limited  liability  company   (collectively   "Licensee"),
licensees of Stations WCDX-FM,  Mechanicsville,  Virginia, WPLZ-FM,  Petersburg,
Virginia,  WGCV-AM,  Petersburg,  Virginia,  and  WJRV-FM,  Richmond,  Virginia,
respectively  (the  "Stations"),  and Radio One,  Inc.,  a Delaware  corporation
("Timebroker").

         1.0      Programming.

         1.1 In consideration  for the mutual  obligations  herein contained and
the payment by Timebroker to Licensee of the sums of money  provided for herein,
Licensee  agrees to sell and  Timebroker  agrees to buy,  beginning June 1, 1999
(the "Commencement Date") and until the earlier of the termination, according to
its terms, of the Asset Purchase Agreement (the "Asset Purchase Agreement" dated
May 6th,  1999) or the  Closing,  as  defined  in the Asset  Purchase  Agreement
between the parties,  or some earlier date on which this  Agreement  terminates,
those certain segments of air time  (hereinafter  referred to as "Sold Time") on
the  Stations.  Subject to the rules and policies of the Federal  Communications
Commission  ("FCC" or "Commission") and the limitations  contained herein,  Sold
Time shall  consist of up to 168 hours per week of  programming  which  shall be
provided  to  Licensee  by  Timebroker,  including  entertainment  programs  and
commercials when and as selected by Timebroker.  Licensee, however, reserves for
use,  at its option,  one hour  between  5:00 and 6:00 a.m.  each  Saturday  and
Sunday.

         1.2 Licensee may produce or present on the Stations  public  affairs or
other informational  programming and such additional programming as it elects to
present during the preemptions provided for in paragraph 1.3 hereof.  Licensee's
public  affairs  programs  shall respond to the needs and interests of Richmond,
Mechanicsville, and Petersburg.




                                       2

         1.3  Timebroker's   programming   shall  consist  primarily  of  music,
commercial announcements,  news and informational programming.  Timebroker shall
not alter the format of any of the stations  without  Licensee's  prior consent.
Licensee  may,  from time to time,  preempt  portions of Sold Time to  broadcast
emergency  information  or  programs  it deems  would  better  serve the  public
interest,  and may  refuse to  broadcast  any  program  and/or  announcement  of
Timebroker should Licensee deem such program and/or  announcement to be contrary
to the public  interest.  However,  such authority  shall not be exercised in an
arbitrary manner or for the commercial  advantage of Licensee.  Timebroker shall
be notified,  unless such advance notice is impossible or impractical,  at least
one week in  advance  of any  preemption  of  Timebroker's  programming  for the
purpose of  broadcasting  programs  Licensee deems necessary to serve the public
interest.  In the  event of any such  preemption,  Timebroker  shall  receive  a
pro-rated  credit for the preempted time against the monthly payment required by
paragraph 3.0 and described in subparagraph (a) of Schedule 3.0 hereof.

         1.4 Timebroker shall broadcast (a) an announcement in form satisfactory
to Licensee at the beginning of each hour to identify each respective  Station's
call sign and city of license,  (b) an  announcement  at the  beginning  of each
segment of Sold Time (i.e.,  at the beginning of each broadcast day) to indicate
that  program  time  has  been   purchased  by   Timebroker,   (c)   sponsorship
identification  announcements  for all commercial  matter  included in Sold Time
that comply with Section 73.1212(a) of the FCC's rules and regulations,  and (d)
any other announcement that may be required by law, regulation, or the Stations'
policy, as provided, in writing, to Timebroker.

         2.0 Record Keeping.

         2.1  Licensee  shall  promptly  provide  Timebroker  with a copy of any
official  correspondence it receives from the FCC or any other federal, state or
local  governmental  authority,  which  relates  in any way  to,  or  alleges  a
violation  by Licensee,  of any law,  rule,  regulation,  ordinance or any other
governmental  requirement.  Licensee also shall continue to be  responsible  for
maintenance of all FCC required logs and records for the Stations, including the




                                       3

public  inspection file and quarterly  lists of community  problems and programs
broadcast in response thereto. In this regard, Timebroker shall, at its expense,
and under Licensee's  supervision,  compile and complete all such logs,  records
and  reports  relating  to the  Stations'  Sold  Time  as are  customary  in the
broadcast industry,  and such logs, records and reports shall be the property of
Licensee,  but shall be available at all times to Timebroker.  Timebroker  will,
forthwith  upon  receipt of same,  furnish to  Licensee  all  correspondence  it
receives  from the public  regarding the  Stations'  operations  or  programming
during Sold Time.

         2.2  Upon  the  request  of  Licensee,  Timebroker  shall  provide  for
Licensee's  approval  a  schedule  describing  the  play  lists  and a day  part
breakdown  of  the  programming  matter  to be  transmitted  by  Timebroker  for
broadcast on each of the Stations  during the week  (Sunday-Saturday)  following
such  request,  and Licensee  will notify  Timebroker by 5:00 p.m. on the Friday
preceding  the week for which the  schedule has been  provided of any  objection
Licensee  has  to  Timebroker's  planned  programming,   based  upon  Licensee's
obligation to provide  programming  consistent with the FCC's Rules.  Timebroker
shall  conform or alter its  programming  schedule to meet any such  objections.
Also,  for any  particular  broadcast day,  Timebroker  shall provide  Licensee,
within two (2) days  following  Licensee's  request,  program and  traffic  logs
setting forth,  respectively,  all of the programming and commercial matter that
was  transmitted  by Timebroker  for broadcast on the Stations.  Such logs shall
include notations that identify the subjects known to have been addressed in any
public affairs and talk shows,  public service  announcements  or other programs
addressing local needs and interests,  and shall identify the sponsor,  the time
and the duration of each commercial announcement.  Timebroker shall also provide
in a timely manner, upon Licensee's advance request, air checks of the Stations'
operations.

         3.0 Payments.  Commencing on June 1, 1999, and on the first day of each
month thereafter during the term of this Agreement,  Timebroker shall pay a time
brokerage  fee to Licensee in the amount and in the manner set forth in Schedule
3.0 attached hereto. In addition,  Timebroker shall make payments to Licensee to
cover  expenses  itemized  in Section  4.0 and




                                       4

Schedule  3.0 prior to their due dates,  which shall be  specified in writing by
Licensee and accompanied by  documentation  of the expense at least fifteen (15)
days in advance of the due date.  Licensee  shall provide  documentation  of the
expenses and monthly  statements to Timebroker  demonstrating  that Licensee has
paid said expenses . In the event Licensee fails to pay any expense,  Timebroker
may  terminate  this  Agreement  or pay the expense  itself,  at its option.  If
Timebroker  elects  the  latter  option  and pays the  expense,  Licensee  shall
promptly repay  Timebroker,  or Timebroker may take a credit toward the Purchase
Price at Closing on the Asset  Purchase  Agreement.  Should  Timebroker  fail or
refuse at any time to timely make the time  brokerage  fee  required  under this
paragraph,  then upon five (5) days' written notice and  opportunity to cure, to
Timebroker,  Licensee may declare this  Agreement null and void such that all of
Timebroker's  rights  hereunder  shall be deemed  forfeited and canceled for all
purposes.  The same shall apply, but on ten (10) days' notice and opportunity to
cure, to the expense payments required  hereunder.  In either event, if Licensee
exercises its right to declare this  Agreement null and void,  Timebroker  shall
(a) vacate the premises of the Stations and remove all of its equipment,  papers
and  materials  within  thirty  (30)  days  after  the  date of  notice  of such
termination,  and (b) be liable  for a  material  breach  of the Asset  Purchase
Agreement.  Should closing on the Asset Purchase  Agreement occur during a month
for which  payments in this  Section 3 have been made,  such  payments  shall be
prorated.

         4.0 Expenses.

         4.1  Timebroker  shall be  permitted  access  to and use of  Licensee's
studio  and  program  production  facilities  at no  additional  cost.  However,
Licensee shall be  responsible  in the amounts and manner  described in Schedule
3.0 for the payment of all fees and expenses relating to the basic operations of
the  Stations  or  necessary  for  Licensee  to  fulfill  its  FCC  obligations,
including,  but not limited to:  salaries,  benefits  and taxes  relating to the
employment  of  Licensee's  managerial  and  clerical  employees,   electricity,
property taxes, rents, and equipment repairs and maintenance.




                                       5

         4.2 All equipment  necessary for  broadcasting  by the Station shall be
maintained  by Licensee,  with  Timebroker's  assistance  when  requested,  in a
condition  consistent  with good  engineering  practice and in compliance in all
material respects with the applicable rules, regulations and technical standards
of the FCC.  All  capital  expenditures  (defined  as any  equipment  repair and
maintenance cost in excess of Two Thousand Dollars ($2,000))reasonably  required
to maintain the  technical  quality of the  Stations'  signal shall be made in a
timely fashion by Timebroker after consultation with Licensee and made available
for use by Licensee at the Stations,  provided that should the parties not close
under the Asset Purchase Agreement for any reason, then at Timebroker's  option,
Timebroker  will  either  continue  to own the  equipment  and may  remove it or
Licensee will purchase the equipment from Timebroker at cost. Should the parties
close, the cost of such capital expenditures will be borne by Timebroker,  but a
credit  against the purchase price for half the cost thereof will be provided at
Closing.

         4.3 All  expenses  associated  with  the  production  and  delivery  of
Timebroker's  programming,  including the salaries and related  compensation  of
Timebroker's employees,  and music license fees shall be the sole responsibility
of Timebroker.

         5.0 Insurance. Timebroker will arrange to include Licensee as a
co-insured  on  Timebroker's  policy  for  appropriate  liability  and  fire and
extended  coverage  insurance  in amounts  reasonably  required  to protect  the
parties  hereto from losses from  liability for personal  injury as well as from
loss by theft, fire and other causes to the Stations' equipment.

         6.0 "Payola" and "Plugola".  Timebroker  agrees that it will take steps
consistent with broadcast  industry  standards to assure that its employees will
not accept any consideration in money, goods, services or otherwise, directly or
indirectly  (including to relatives)  from any person or company for the playing
of  records,  the  presentation  of  any  programming  or the  broadcast  of any
commercial  announcement  over the Stations  without  reporting  the same to the
management  of the  Licensee  and without  such  broadcast  being  announced  as
sponsored.  Timebroker  understands that violation of this provision is "payola"
and  constitutes a federal  crime.  It is further  understood and agreed that no
commercial  message  ("plug") or undue




                                       6

reference  shall  be made in  programming  presented  over the  Stations  to any
business  venture,   profit-making   activity  or  other  interest  (other  than
non-commercial announcements for bona fide charities, church activities or other
public service  activities)  in which  Timebroker or anyone else are directly or
indirectly interested without the same having been approved by the management of
Licensee and said broadcast being announced as sponsored.

         7.0 Political  Broadcasts.  Timebroker  agrees that any spot or program
time sold to any  candidates  for  political  office or  person(s)  supporting a
candidate will be sold in strict  accordance  with FCC rules and regulations and
will be supported by  documentation  as required by the FCC. Such  documentation
will be  transmitted  to  Licensee  in a  timely  manner  for  inclusion  in the
Stations'   "political   file."  Timebroker  will  coordinate  the  Timebroker's
political sales policies with Licensee prior to any pre-election period.

         8.0 Compliance With Laws/Indemnification. Timebroker and Licensee shall
comply in all material  respects with all state,  local and federal laws,  rules
and  regulations,  including the rules,  regulations and policies of the FCC, as
well as with all other  obligations on their part under this Agreement,  and the
failure of either to do so shall constitute a breach of this Agreement, provided
that the  non-breaching  party  shall  provide  thirty  (30)  days'  notice  and
opportunity to cure to the allegedly  defaulting  party (except that such thirty
day period shall not apply to defaults under Section 3.0.). In the event of such
breach,  Timebroker or Licensee,  as the case may be, hereby indemnifies,  makes
whole and holds harmless the other party, its officers, directors, shareholders,
members  and  employees  of and from  any and all  costs,  liabilities,  claims,
obligations and expenses,  including  reasonable attorneys fees, which the other
party may incur  arising from such breach or default.  Further,  Timebroker  and
Licensee hereby indemnify and hold each other harmless against all liability for
libel,  slander,  illegal competition or trade practices,  infringement of trade
marks,  trade names,  or program  titles,  violation  of rights of privacy,  and
infringement of copyrights and property  rights  resulting from the broadcast of
programming  furnished or broadcast by the other party. These mutual obligations
shall survive any  termination  of this  Agreement and shall  continue until the
expiration of all  applicable



                                       7

statutes of limitation and the conclusion and payment of all judgments which may
be  rendered  in all  litigation  which  may have been  commenced  prior to such
expiration.  Breach of the  obligations  in this paragraph by either party shall
not constitute a breach of the Asset Purchase Agreement.

         9.0 Control of  Station.  Anything  to the  contrary in this  Agreement
notwithstanding,  Licensee shall retain  ultimate  control of all aspects of the
Stations'  operations  and Timebroker  shall in no way represent  itself or hold
itself out as the Stations'  licensee.  Licensee shall employ a station  manager
whose principal workplace during regular business hours, five (5) days per week,
shall be the Stations'  studios.  Licensee  shall employ at least one additional
person who shall be  present at the  Stations'  studios  at least  during  those
regular business hours when Licensee's manager must be elsewhere, or shall share
such an employee with the  Timebroker.  The parties shall jointly  determine who
this shared employee will be and what his or her salary will be.

         10.0 Employees. As of May 31, 1999, Licensee will dismiss all employees
of the Stations except for the Licensee's station manager. Timebroker may, prior
to the  Commencement  Date,  extend offers of employment to any of the Stations'
dismissed  employees.  Licensee shall be responsible,  consistent with state law
and  internal  station  policy,  for  payment of all salary and other  benefits,
whether monetary or otherwise (including,  without limitation,  accrued vacation
time),  to which such  dismissed  employees of the Stations are entitled for all
periods  up to and  including  May  31,  1999,  and  shall  indemnify  and  hold
Timebroker harmless therefor.

         11.0  Cure of  FCC-Related  Deficiencies.  It is the  intention  of the
parties that this Agreement  comply in all material  respects with the rules and
policies of the FCC  concerning  agreements  of this  nature.  In the event that
there  is any  complaint,  inquiry,  investigation,  or  proceeding  at the  FCC
concerning this Agreement and the relationship  between the parties, the parties
shall  cooperate fully and share equally the costs in responding to such matter.
The  parties  also  agree to modify  this  Agreement  in any  reasonable  manner
required to maintain  compliance



                                       8

with FCC rules and policies, preserving to the maximum extent possible the basic
business terms and conditions  contained herein.  Should such modification prove
impossible, this Agreement may be terminated by either party.

         12.0     Term

         12.1 The term of this Agreement  shall be from June 1, 1999,  until the
earlier of (a) Closing under the Asset Purchase  Agreement,  (b)  termination of
the Asset Purchase  Agreement,  (c)  termination  of this Agreement  pursuant to
paragraph  3.0 (d)  termination  of this  Agreement  pursuant to paragraph  12.2
hereof, or (e) termination of this Agreement pursuant to paragraph 11 hereof.

         12.2 In the event of a material  default in performing  the  respective
duties and  obligations  as set forth in this  Agreement  (with the exception of
Timebroker's  payment  requirements  as  described  in  paragraphs 3 and 4), the
non-defaulting party may terminate this Agreement without penalty, provided that
such default  shall not have been cured by the  defaulting  party within  thirty
(30) days after written notice thereof.

         12.3 In the event of  termination of this  Agreement,  it is understood
that  Timebroker  reserves  the  right to  ownership  of logos  and  positioning
statements which it develops during the term of this Agreement, and Licensee may
not make use of any such materials without the consent of Timebroker.

         12.4 In the event of Licensee's  termination  of this  Agreement due to
Timebroker's  default,  all agreements or contracts for advertising  during Sold
Time then in existence  shall belong to and be the property of Licensee,  except
that  Licensee  shall have the option  whether  to assume  contracts  with terms
longer than ten (10) weeks. Licensee shall (a) have the duty to perform all such
assumed agreements or contracts,  and (b) be entitled to collect and receive the
money thereafter derived therefrom; and Timebroker will forthwith assign same to
Licensee and turn over to Licensee all books and records relating to the sale of
advertising for broadcast  exclusively over the Stations.  Timebroker  shall, at
such time, pay over to Licensee any money or other  consideration  it shall have
received as  "pre-payment"  for such  advertising  which




                                       9

Licensee  may  thereafter  undertake to broadcast  over the  Stations.  Licensee
indemnifies and holds  Timebroker  harmless  against any  nonperformance  of any
assumed agreement or contract. All uncollected revenue for advertising broadcast
during Sold Time prior to such  termination  shall belong to, be the property of
and be for the benefit of Timebroker.

          13.0 Proration. Licensee shall be responsible for all expenses arising
out of  the  business  of the  Stations  until  11:59  p.m.  on  May  31,  1999.
Thereafter,  expenses  arising  out of the  business  of the  Stations  shall be
treated as outlined  above in paragraph  3.0 and Schedule  3.0. All  overlapping
expenses shall be prorated or  reimbursed,  as the case may be, as of 11:59 p.m.
on May 31, 1999.

         14.0  Inspection  of Books and  Records.  To the  extent the FCC or any
third party is entitled by law or contract to review any of  Timebroker's  books
and records  relating to the  Stations'  operation  during Sold Time,  including
financial  books and  records,  whether  pursuant to  contracts  entered into by
Licensee or otherwise,  e.g., with ASCAP,  BMI, or SESAC,  Timebroker will, upon
reasonable notice,  make such books and records available for such third party's
inspection  and, to the extent  required or made necessary by law or contractual
obligations of Licensee,  for inspection by Licensee. In addition,  upon request
by Licensee, Timebroker will forthwith supply Licensee with all information, and
all books and records  necessary  for  verification  thereof,  which will enable
Licensee to prepare,  file or maintain  the records and reports  required by the
FCC, ASCAP, BMI, SESAC and like entities.

         15.0 No Carry-Over  Agreements  Without Consent.  Timebroker shall seek
consent from Licensee to make agreements  which shall require use of time on the
Stations  subsequent to the expiration or  termination  of this Agreement  which
exceed six (6) months in duration,  and shall in no other way obligate  Licensee
without Licensee's written consent.

         16.0     Accounts Receivable.  After the Commencement Date both parties
shall be responsible  for collection of their own Accounts  Receivable  that are
outstanding and unpaid , except for those Accounts Receivable which Licensee has
instituted  litigation  to collect or




                                       10

referred to a collection  agency as of the date of this  Agreement and which are
identified  in Schedule  16.0.  All payments  received by Timebroker or Licensee
from any person who makes a payment with respect to any Accounts  Receivable for
the other  party  shall be  promptly  paid over to the other  party,  attempting
wherever possible to do so within fifteen (15) days of receipt thereof. Licensee
shall continue timely to pay  commissions on the same percentage  basis as prior
to the Commencement  Date to employees,  agencies and  representatives  on these
Accounts  Receivable  on the  15th  and  last  day of  each  month,  and to make
reasonable  efforts in the  ordinary  course of business to collect the Accounts
Receivable.  The parties will make every effort to cooperate  with each other to
ensure  that  both are  paid  monies  owed  them  promptly,  but  without  undue
disruption to the parties' accounting systems or Timebroker's relationships with
customers.

         17.0 Force Majeure Event. If either Timebroker or Licensee is prevented
from performing its obligations hereunder by a Force Majeure event (i.e., fires,
acts of God,  orders of civil or  military  authorities  or other  contingencies
beyond the reasonable  control of the parties),  and such a situation  cannot be
corrected  within a period of thirty (30) days,  this  Agreement  shall,  at the
option of either of the  parties  hereto,  terminate  and,  except as  otherwise
provided  herein,  the parties'  obligations  accruing beyond that time shall be
terminated;  and  neither  shall be  liable  to the  other  for a breach  caused
thereby.  Neither  Timebroker nor Licensee shall be required to correct problems
caused by a Force Majeure event which  eliminates  its ability to carry out this
Agreement.

         18.0 Waiver of Breach.  A waiver by either  Timebroker or Licensee of a
breach of any  provision of this  Agreement  shall not be deemed to constitute a
waiver of any preceding or subsequent  breach of the same provision or any other
provision.

         19.0 Entire  Agreement.  This writing  constitutes the entire agreement
between  Timebroker  and  Licensee  pertaining  to  time  brokerage,  all  prior
understandings being merged herein. This Agreement may not be changed, modified,
renewed, extended or discharged, except as specifically provided herein or by an
agreement in writing  signed by the parties  hereto.  It is recognized  that the
obligations  of Licensee  and  Timebroker  hereunder  are subject to  applicable



                                       11

federal, state and local law, rules and regulations,  including, but not limited
to, the Communications Act of 1934, as amended, and the rules and regulations of
the FCC.

         20.0  Notices.  All notices  called for herein  shall be in writing and
shall either be delivered by hand  delivery,  evidenced by written  receipt;  by
Federal Express, or other similar courier service or telecopier and evidenced by
written receipt; all of which shall be addressed as follows:

                                  Schedule 3.0

                                  Compensation

         Timebroker will pay Licensee monthly as follows:

         (a)      $233,000.00 (the time brokerage fee); plus

         (b) An  amount  equal to  Licensee's  expenses  to be paid  during  the
following month starting on the Commencement Date for the following:

                  (i)      salaries,   benefits   and  taxes   relating  to  the
                           employment of Licensee's employees;

                  (ii)     electric costs;

                  (iii)    property taxes and rents;

                  (iv)     equipment repairs and maintenance.

          The expenses  defined in (i) - (iv) above are  estimated not to exceed
Forty Two  Thousand and Five Hundred  Dollars  ($42,500) in any month  ("Expense
Amount").  Licensee  shall be  required to submit to  Timebroker  on a quarterly
basis an accurate account of expenses detailed in (i) - (iv) above, supported by
appropriate  documentation.  In no event shall Timebroker be required to pay any
amount in excess of the actual  expenses.  Thus,  in the event that total actual
expenses  for any quarter are less than the expenses  paid during that  quarter,
the parties shall in good faith and supported by appropriate  documentation make
adjustments  thereto and any excess amount paid by Timebroker  shall be remitted
by  Licensee   within   fifteen   (15)  days  of  the  close  of  the   quarter.
Notwithstanding the foregoing,  if such expenses in any month exceed the Expense
Amount, Timebroker and Licensee shall each pay one half of the cost in excess of
the Expense Amount.
