pre-emptive rights to crux

The Deloitte independent report states that Crux is subject to a pre-emptive rights clause. IMO Delloites are negligent in not determining or stating when and how these rights could come into play in any transfer of interest in Crux. They do indicate that the pre-emptive rights are likely to have a major affect on Crux value. This could indicate if SGH and NXS management are indeed acting for Shell/Osaka interests as many watchers of actions by directors and management over the years now believe.
Will SGH if they gain control of NXS have to determine a cash price for Nexus's 17% of Crux to offer to Shell & Osaka? Would Shell and Osaka accept SGH as a partner in Crux.
