In a move hailed by environmentalists as its first act of responsibility toward area resident Dan Fanshaw, Exxon Corp. announced that it will donate $70 million toward cleaning up Fanshaws life. Among the damage for which Exxon will compensate Fanshaw: his failure to get into medical school, the May 97 death of his beloved dog Max, and his increasing addiction to anti-depressants. Its a mess, Exxon spokesperson David Haller said. But we are committed to cleaning it up.
