In such considerations, the Board of Directors may consider all or certain of such factors as a whole and may or may not assign relative weights to any of them. The foregoing is not intended as a definitive list of factors to be considered by the Board of Directors in the discharge of their fiduciary responsibility to the Corporation and its shareholders, but rather to guide such consideration and to provide specific authority for the consideration by the Board of Directors of factors which are not purely economic in nature in light of the circumstances of the Corporation and its subsidiaries at the time of such proposed Business Combination.
