This section applies where—
Both the grantor of the option and the person to whom the option is granted shall be treated for the purposes of this Act as if section 17(1) did not apply for the purposes of calculating the consideration and, accordingly, as if the amount or value of the consideration was its actual amount or value.
Where the option is granted wholly or partly in recognition of services or past services in any office or employment, the value of those services shall not be taken into account in calculating the actual amount or value of the consideration.
