Statement on Form 8-A/A filed on January 27, 2000 (collectively, the

following at the end thereof:

         On June 7, 2002, the Company and the Harris Trust Company of New York,

Amendment") to the Amended and Restated Rights Agreement, dated as of January
20, 2000, between the Company and the Rights Agent (the "Rights Agreement"). The
2002 Amendment effected certain technical amendments necessary to reflect the
Company's previously announced 2-for-1 stock split, which is expected to occur
on June 28, 2002.

         Among other things, the 2002 Amendment amends the 2000 Rights Agreement
to (1) reduce the portion of a share of Series A Junior Participating Preferred
Stock (the "Preferred Shares") for which each preferred share purchase right
(each "Right") may become exercisable, under the terms set forth in the Rights
Agreement, from one three-hundredth of a Preferred Share to one six-hundredth of
a Preferred Share and (2) to reduce the exercise price for each Right from $400
to $200.

         The 2002 Amendment is attached hereto as Exhibit 2 and incorporated
herein by reference. The foregoing summary of the 2002 amendment is qualified in
its entirety by reference to the full text of such exhibit.
