I think that the first thing that they need to do is release the contract signed with Exon, the second thing is to do a quicker search of whether the government received a US$20 million signing bonus.
i would have expected that any agreement include provisions to deal with fluctuations in the price of oil.
VVP's suggestion is a good one. Hope that the govt. heads in that direction. Though, my understanding is that the terms given at this point are good ones. Cannot really be definitive until the full contract is revealed and comparisons, analysis can be made.
