The foregoing right of indemnification shall not be exclusive of other rights to which those seeking indemnification may be entitled. The Corporation may maintain insurance, at its expense, to protect itself and any such person against any such fine, liability, cost or expense, including attorney's fees, whether or not the Corporation would have the legal power to directly indemnify him against such liability.
