The fight to pull First Mariner Bancorp from the brink has taken its toll on Edwin F. Hale Sr., the bank's founder and chief executive officer. Hale, a larger-than-life Baltimore personality, has taken steps to shore up the bank's finances and his own. He said he avoided personal bankruptcy because he feared that would have sparked a run on the bank and jeopardized the jobs of 800 employees. These are some key numbers behind the story of Hale, who is pinning his hopes on a coming stock offering to raise as much as $20 million - a step considered crucial to the bank's survival.
