oxiana top of self funding resources takeovers, page-27

Fzanc,
Thanks for that. In reading that page and esp points h, i, j and k, it would appear that there are multiple reasons to break the deal, either by
a) OXR directors changing their minds with a t/o bid lobbed in from someone else (item h)
b) ZFX if a takeover of OXR gains 50% of OXR shares,
(item i) (unlikely to happen - too short a time frame)
c) ZFX if a takeover of OXR is proposed that ignores ZFX (item j)

What is the difference between a "Mutually Exclusive Competing Proposal" and a "Competing Proposal" (items j and k)? When I read it in context, I cannot seem to find a difference.
