expected value of the Antenna Facilities may be reflected in an adjustment to
the Base License Fee. Such an adjustment may be defined at the time at which
Licensor seeks Licensee's approval for modifications to the Antenna Facilities
described in Attachments A or C.

will be reduced by the corresponding fee as defined in this agreement.

sole cost and expense, prepare and deliver to Licensor working drawings, plans

the Licensee's Antenna Facilities and specifically describing the proposed
construction and work. No work shall commence until Licensor has approved, in
writing, Exhibits A, B, C and D. Such approval will not be unreasonable

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

shall have the right to engage outside consultants to resolve interference
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

the installation of the Antenna Facilities proposed hereunder and which have
been damaged by Licensee, or any of its agents, representatives, employees,
contractors, subcontractors, or invitees, excepting damage caused by ordinary
wear and tear or by others.

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

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.

sanitary and safe condition and in good repair and free of any defects at all
times during this Lease. Licensee, at its sole expense and risk, shall ensure
