Dickson, 38, a former president of Irvine-based Lincoln Savings & Loan, pleaded guilty in Los Angeles federal court to bank fraud stemming from the thrift’s 1989 collapse. As part of his plea, Dickson of Scottsdale, Ariz., agreed to cooperate with federal officials in their continuing investigation of Charles H. Keating Jr., former chairman of American Continental Corp., the parent of Lincoln.
