An undertaking given by any person, in or in connection with payment for shares in a company, to do work or perform services or to do any other thing, if it is enforceable by the company apart from this Chapter, is so enforceable notwithstanding that there has been a contravention in relation to it of a provision of this Chapter or Chapter 5.

This is without prejudice to section 606 (power of court to grant relief etc in respect of liabilities).
