(a) A transaction entered into on or pursuant to the rules of a security-based swap execution facility shall not be void, voidable, subject to rescission, otherwise invalidated, or rendered unenforceable as a result of a violation by the security-based swap execution facility of the provisions of section 3D of the Act or the Commission's rules thereunder.

(b) A security-based swap execution facility shall, as soon as technologically practicable after the time of execution of a transaction entered into on or pursuant to the rules of the facility, provide a written record to each counterparty of all of the terms of the transaction that were agreed to on the facility, which shall legally supersede any previous agreement regarding such terms.
