--------------------

* Effect of dilutive securities would have been anti-dilutive; accordingly, the
  amounts are excluded from shares used in computing diluted earnings per share.

Shares issuable from the convertible subordinated debentures were excluded from
the calculation of diluted earnings per share because their effect would have
been anti-dilutive.
