Waiver or Delay No failure to exercise or delay by a party in exercising any right, power, or remedy under this License Agreement operates as a waiver of such right, power, or remedy. A single or partial exercise of any right, power, or remedy does not preclude any other or further exercise of that or any other right, power, or remedy. A waiver is not valid or binding on the party granting the waiver unless made in writing.
Excusable Delays Except with respect to defaults of subproviders, the Engineer shall not be in default by reason of any failure in performance of this contract in accordance with its terms (including any failure to progress in the performance of the work) if such failure arises out of causes beyond the control and without the default or negligence of the Engineer. Such causes may include, but are not restricted to, acts of God or the public enemy, acts of the Government in either its sovereign or contractual capacity, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and unusually severe weather.
Unavoidable Delays Delays due to acts of God, acts of public agencies, labor disputes, strikes, fires, freight embargoes, inability (despite the exercise of due diligence) to obtain supplies, materials, fuels or permits, or other causes or contingencies (excluding financial inability) beyond the reasonable control of Landlord or Tenant, as applicable. Landlord shall use commercially reasonable efforts to provide Tenant with prompt notice of any Unavoidable Delays.
