A prime contract (or change or modification to a prime contract) under which a certificate under
section 3702(b) of this title is required shall contain a provision that the price of the contract to the United States, including profit or fee, shall be adjusted to exclude any significant amount by which it may be determined by the head of the agency that such price was increased because the contractor (or any subcontractor required to make available such a certificate) submitted defective cost or pricing data.
