Harold Hamm, chief executive of oil driller Continental Resources who is embroiled in a bitter divorce, offered to pay his former wife $974.8 million, but she rejected a hand-written check delivered to her legal team, his lawyer said on Tuesday. Hamm's offer to pay ex-wife Sue Ann Arnall immediately the full cash value of what he owes based on a November divorce ruling by an Oklahoma County judge was rejected, Hamm's lawyer, Michael Burrage, said in an emailed statement.
