Gujarat launched its off-market takeover for Rey back in June, initially offering one Gujarat share for every five Rey shares.
Later offers from Gujarat also included a cash component of 9c per Rey share, and the extension applies to both the scrip-based and cash options of the proposal.
Hong Kong-based Crosby Capital withdrew its 19.5c per Rey share takeover offer less than two weeks ago.
Rey shares closed up 2.6% yesterday to 20c while Gujarat shares closed up 6c to 75c.
