All or any of the requirements of—
section 561 (existing shareholders' right of pre-emption), or
section 562 (communication of pre-emption offers to shareholders)
may be excluded by provision contained in the articles of a private company.
They may be excluded—
generally in relation to the allotment by the company of equity securities, or
in relation to allotments of a particular description.
Any requirement or authorisation contained in the articles of a private company that is inconsistent with either of those sections is treated for the purposes of this section as a provision excluding that section.
A provision to which section 568 applies (exclusion of pre-emption right: corresponding right conferred by articles) is not to be treated as inconsistent with section 561.
