<PAGE>   4
or part thereof, commencing on the date herein shown as the date of this
Agreement. All payments shall be made to Licensor at the address given in
Section 18 of this Agreement. Licensor and Licensee agree to use their good
faith efforts to refrain from disclosing the financial terms of this agreement.

with the provisions hereof.

               The Licensee reserves the right to cancel this Agreement at any
time upon giving ninety (90) days written notice to the Licensor. If Licensee
elects to remove any or all of the Antenna Facilities equipment, the annual fee
will be reduced by the corresponding fee as defined in this agreement.

        4. Use

               Licensee shall use the Antenna Facilities solely for the purposes
of providing the services detailed in Exhibit A of this Agreement and which it

               (b) Licensee will ensure that the installation, maintenance and
operation of Licensee's Antenna Facilities will not penetrate the rooftop and in
no way damage the Building, interfere with the use of the Building or interfere
with the operation of communications devices by Licensor or by other
pre-existing lessees or licensees of the Licensor. In order to avoid such
interference, Licensee shall, at its own expense, prepare and conduct an
evaluation of the potential for such interference before installing and
operating the Antenna Facilities, and shall submit a copy of such findings to
Licensor within ten days. In addition, following the installation of the Antenna
Facilities, Licensee shall, at its own expense, prepare and conduct an
evaluation of the potential for such interference within ninety-six (96) hours
if requested to do so by Licensor, whether upon Licensor's own behalf or as a
result of concerns expressed by any pre-existing lessees or licensees. Licensor

issues arising between Licensees operating equipment on the roof, and between
Licensor's Licensees and off premises operators. Licensor shall have the
absolute right to require all its Licensees to implement any such consultant's
recommendations for resolution of interference problems. If such damage or
interference is occurring, Licensee shall correct the same within seventy-two
(72) hours of receipt of written notice thereof. Licensor reserves the right to
disconnect power to any such Licensee's Equipment which Licensee fails to
correct after proper notification and waiting period.

               (h) Licensee shall have the right to amend Exhibits A, C and D,
from time to time, with the express written consent of Licensor for the purpose
of serving additional occupants of the building. Such consent shall not be
unreasonably withheld, conditioned or delayed by Licensor; however, the parties
recognize that, in the event of changes that will materially increase the value
of the Antenna Facilities, such consent may be withheld pending agreement upon
the terms of modifications to the Base License Fee, as contemplated in Section
2(b) above. Following Licensor's consent to amendment of Exhibits A, C and D,
all terms and conditions of this Construction Section (Section 6) shall apply.

        7.  Licensee's Covenants

a survey of structural integrity and a review and correction of any loose bolts,
fittings or other appurtenances. Licensee shall provide a written certification
of such inspections to Licensor not more than 10 days following each such
inspection. In the absence of such a certification, Licensor shall have the
right (but not the obligation) to conduct or arrange for such an inspection and
corrective action and to charge Licensee for such costs.

that are inconsistent with those plans (as they may from time to time be amended
with the consent of Licensor) or for the display of advertising or other visual
displays with significant aesthetic impacts.

conditions, which emergency situations and conditions shall be reasonably
determined by Licensor.

               (d) Licensee agrees to be responsible for any damage caused to
the Building Spaces, Equipment Rooms, Pathways and/or any other property owned
by Licensor or any lessee or licensee of Licensor which may be caused by
