Section 89(1), section 90(1) to (5) or section 90(6) may, as applying to allotments by a private company of equity securities or to such allotments of a particular description, be excluded by a provision contained in the memorandum or articles of that company.

A requirement or authority contained in the memorandum or articles of a private company, if it is inconsistent with any of those subsections, has effect as a provision excluding that subsection; but a provision to which section 89(3) applies is not to be treated as inconsistent with section 89(1).
