ITEM 5. OTHER EVENTS

     On December 19, 2001, the Registrant filed a notice with the Nasdaq
erroneously reporting that the Registrant's board of directors had declared a
fourth quarter dividend of $0.25 per share. The notice should have stated the
fourth quarter dividend as $0.20 per share, which is consistent with the
Registrant's past dividend history. The $0.20 per share dividend is payable on
January 10, 2002, to stockholders of record as of December 28, 2001. A copy of
the press release distributed by the Registrant correcting this erroneous notice
is attached hereto as Exhibit 99.1.

          None.

     (b)  PRO FORMA FINANCIAL INFORMATION.

          None.

     (c)  EXHIBITS.
