RIO--WRN DEAL PROVISIONS (SPECULATION)
IMO both parties would not have entered this agreement without some preliminary understanding as to ultimate price--
Just, and only for example the price would not exceed $8.34, nor be less that $4.84 in USD,
both parties agreeing to negotiate in good faith over next 12 months
Also, a provision that if no transaction is completed by June 30th 2022 (for example) then unless extended, the entire agreement would be terminated. WRN would keep the money, RIO could sell their shares (WRN would have first right to buy at the then market price).
