(a) Common share equivalents had a dilutive effect on net earnings from
    continuing operations per share for the second quarter and six months ended
    June 30, 1996, and therefore were included in the primary and fully diluted
    earnings per share computation.  Common share equivalents had an
    anti-dilutive effect on net earnings from continuing operations per share
    for the second quarter and six months ended June 30, 1997, and therefore
    were not included in the primary and fully diluted earnings per share
    computation.

(b) The Preferred Stock and related dividend requirement had an anti-dilutive
    effect on earnings per share for the second quarters and six months ended
    June 30, 1997 and 1996, and, therefore, were excluded from the fully
    diluted earnings per share computation.
