A prime contract (or change or modification to a prime contract) under which a certificate under
section 3502(b) of this title is required shall contain a provision that the price of the contract to the Federal Government, including profit or fee, shall be adjusted to exclude any significant amount by which it may be determined by the head of the executive agency that the price was increased because the contractor (or any subcontractor required to make the certificate available) submitted defective cost or pricing data.
