written notice of acceptance within the specified period, or if Tenant waives
its right of first refusal within such fifteen-day period, or if any of the
foregoing conditions to the exercise by Tenant of this right of first refusal
shall not be fully satisfied, Tenant shall be deemed not to have exercised this
right of first refusal and the provisions of this paragraph shall be of no

this Lease, provided Tenant is not in default of any of its obligations under
this Lease, in the event of a non-correctable permanent or intermittent loss or
corruption of the data flow of the satellite transmission reception to the
satellite dishes, Tenant shall have the option to terminate this Lease by
tendering to the Landlord a Notice of Tenant's intention to terminate this
lease. Tenant shall give Landlord at least thirty (30) days prior written notice
