Excuse for Nonperformance or Delayed Performance Except with respect to defaults of subcontractors, Contractor/Vendor shall not be in default by reason of any failure in performance of this contract in accordance with its terms (including any failure by Contractor/Vendor to make progress in the prosecution of the work hereunder which endangers such performance) if Contractor/Vendor has notified the Commission or designee within 15 days after the cause of the delay and the failure arises out of causes such as: acts of God; acts of the public enemy; acts of the State and any other governmental entity in its sovereign or contractual capacity; fires; floods; epidemics; quarantine restrictions; strikes or other labor disputes; freight embargoes; or unusually severe weather. If the failure to perform is caused by the failure of a subcontractor to perform or to make progress, and if such failure arises out of causes similar to those set forth above, Contractor/Vendor shall not be deemed to be in default, unless the services to be furnished by the subcontractor were reasonably obtainable from other sources in sufficient time to permit Contractor to meet the contract requirements. Upon request of Contractor, the Commission or designee shall ascertain the facts and extent of such failure, and, if such officer determines that any failure to perform was occasioned by any one or more of the excusable causes, and that, but for the excusable cause, Contractor’s progress and performance would have met the terms of the contract, the delivery schedule shall be revised accordingly, subject to the rights of the State under the clause entitled (in fixed-price contracts, “Termination for Convenience,” in cost-reimbursement contracts, “Termination”). (As used in this Paragraph of this clause, the term “subcontractor” means subcontractor at any tier).
