A public company must not allot shares as fully or partly paid up (as to their nominal value or any premium on them) otherwise than in cash if the consideration for the allotment is or includes an undertaking which is to be, or may be, performed more than five years after the date of the allotment.
If a company allots shares in contravention of subsection (1), the allottee is liable to pay the company an amount equal to the aggregate of their nominal value and the whole of any premium (or, if the case so requires, so much of that aggregate as is treated as paid up by the undertaking), with interest at the appropriate rate.
Where—
the allottee is liable to pay the company, at the end of the period so allowed, an amount equal to the aggregate of the nominal value of the shares and the whole of any premium (or, if the case so requires, so much of that aggregate as is treated as paid up by the undertaking), with interest at the appropriate rate.
References in this section to a contract for the allotment of shares include an ancillary contract relating to payment in respect of them.
