(1) Nothing in this
Act prevents a person from agreeing to extend or shorten a limitation period
provided for under this Act.
(2) Despite subsection
(1), a provision in, or condition of, an agreement is of no effect if it
purports to —
(a)
exclude the operation of section 33, 36 or 38; or
(b)
extinguish (rather than bar) a right or title in relation to an action in a
manner that would be inconsistent with a provision of Part 5.
