8.       MAINTENANCE OF EQUIPMENT.

         (a) The transmitter equipment and antennas used for the Station's
broadcasts owned by One-On-One Radio (the "Transmission Equipment") shall be
maintained by One-On-One Radio in a condition consistent with good engineering
practices and in compliance in all material respects with the Act and all other
applicable rules, regulations and technical standards of the FCC. One-On-One
Radio shall maintain power and modulation of the Station broadcasts in a manner
consistent with One-On-One Radio's past practices. All capital expenditures

Radio.

         (b) All equipment necessary for the delivery of the Programming shall

10.      CONTROL OF THE STATION.

         During the term of this Agreement, One-On-One Radio shall maintain
control over the Station's technical facilities and Unica agrees that it will
permit One-On-One Radio to take any and all steps necessary to maintain such
control continuously throughout the term of this Agreement. One-On-One Radio and
Unica acknowledge and agree that One-On-One Radio's responsibility to retain
control is an essential element of the continuing validity and legality of this
Agreement. One-On-One Radio shall provide and pay for: (a) a General Manager of
the Station, who shall report solely to, and be accountable solely to,
One-On-One Radio and who shall direct the day-to-day operations of the Station;
and (b) such other engineering, programming and other personnel as are necessary
to fulfill One-On-One Radio's obligations under this Agreement. One-On-One Radio
shall retain control, said control to be reasonably exercised, over the
policies, programming and operations of the Station, including, without
limitation, the right to decide whether to accept or reject any programming or
advertisements, and the right to take any other actions necessary to comply with
the laws of the United States and the rules, regulations and policies of the
FCC. One-On-One Radio shall maintain its main studio within the Station's
principal community contour and Unica shall take such actions as One-On-One
Radio may reasonably request to ensure such requirements are met. Unica shall
not represent, warrant or hold itself out as the Station's owner and shall sell
all advertising time and enter into all agreements in its own name. One-On-One
Radio reserves the right to refuse to broadcast any program or programs
containing matter which is, or in the reasonable opinion of One-On-One Radio may
be, violative of any right, law, or governmental rule, regulation or policy.

11.      SPECIAL EVENTS.

         One-On-One Radio has the right to reject any of the Programming and to
substitute on a temporary basis a program that, in the reasonable opinion of
One-On-One Radio, is of greater local or national importance. One-On-One Radio
confirms that no Programming shall be rejected on the basis of Programming
performance or ratings, advertiser reaction or the availability of alternative
programming (including, but not limited to, sporting events or paid programming)
that One-On-One Radio believes to be more profitable or more attractive. In the
event of such rejection and substitution, One-On-One Radio shall give Unica
written notice of such rejection and substitution, and the reasons therefor, at
least three (3) weeks in advance of the scheduled broadcast, or as soon
thereafter as possible (including an explanation of the cause of any lesser
notice). In the event of such preemption, Unica shall receive a payment credit
in an amount equal to the loss of revenue by Unica during the time its
Programming was pre-empted, which shall equal the loss of the Station's local
and national revenues and the Station's allocation of Radio Unica network
revenues. The Station's allocation of Radio Unica network revenues shall be
equal to the percentage of Radio Unica network revenues that is the same
percentage determined by dividing the Hispanic population of the Chicago market
by the total Hispanic population reached by the Radio Unica network.

12       FORCE MAJEURE.

         Any failure or impairment (I.E., failure to broadcast at Station's full
authorized power) of facilities or any delay or interruption in broadcast
programs, or failure at any time to furnish facilities, in whole or in part, for
broadcasting, due to any acts of God, strikes or threats thereof or FORCE
MAJEURE or due to any other causes beyond the reasonable control of One-On-One
Radio or Unica shall not constitute a breach of this Agreement and One-On-One
Radio or Unica, as the case may be, will not be liable to the other party hereto
therefor, provided such party uses reasonable diligence to correct such failure
or impairment as soon as is reasonably possible.

13       STATION'S IDS.

         One-On-One Radio hereby grants to Unica an exclusive license to use
such call letters and other identifiers as are currently used or in the future
may be used by the Station (the "Station's Licensed Identifiers") in connection
with the broadcast of Unica's programs on the Station, but for no other purpose.
The license granted herein shall expire on the Closing Date or upon the
expiration or earlier termination of this Agreement. Unica shall use the
Station's Licensed Identifiers in Unica's programming in a manner consistent
with the use thereof by One-On-One Radio in broadcasts of the Station
immediately prior to the Operational Commencement Date during the entire term of
this Agreement and as may be required by the Act or the rules, regulations and
policies of the FCC. In addition, One-On-One Radio agrees, at Unica's cost, to
cooperate with Unica in applying for a change or changes in the Station's call
sign in accordance with the terms of the Asset Purchase Agreement, so long as
such new call sign is not offensive or contrary to the public interest.

14       PAYOLA.

         Unica shall provide One-On-One Radio with payola affidavits,
substantially in the form attached hereto as Attachment A, signed by such of
Unica's employees and at such times as One-On-One Radio may reasonably request
in writing, and shall notify One-On-One Radio promptly of any violations it
learns of relating to the Act, including Sections 317 and 508 thereof.

15       COMPLIANCE WITH LAW AND OTHER AGREEMENTS.

         Unica and One-On-One Radio shall, throughout the term of this
Agreement, comply in all material respects with the Act, the rules, regulations
and policies of the FCC, the terms of the Station's FCC licenses and all other
laws and regulations applicable to the conduct of the Station's business.

all liability, including without limitation all reasonable attorneys fees,

23       CONSTRUCTION.

         This Agreement shall be construed in accordance with the internal
substantive (that is, without reference to conflict of) laws of the State of
Delaware and the obligations of the parties hereto are subject to all Federal,
state or municipal laws or regulations now or hereafter in force and to the
regulations and policies of the FCC and all other governmental bodies or
authorities presently or hereafter duly constituted. The parties believe that
the terms of this Agreement meet all of the requirements of current FCC policy
for time brokerage agreements for radio stations and agree that they shall
negotiate in good faith to meet any FCC concern with respect to this Agreement
