Jan 18 (Reuters) - Canadian oil and gas producer Suncor
Energy Inc SU.TO said it reached an agreement to buy Canadian
Oil Sands Ltd COS.TO , after raising the all-stock offer,
valuing the deal at about C$6.6 billion ($4.55 billion),
including debt.
Suncor will now offer Canadian Oil Sands shareholders 0.28
of a Suncor share for each Canadian Oil Sands share they hold,
higher than the initial bid of 0.25 shares offered in October.
Canadian Oil Sands has a 36.7 percent stake in Syncrude, the
oil-sands mining consortium in northern Alberta that is Canada's
largest single source of crude oil.
