Purchase Rights (3)



This Registration Statement relates to the registration of additional securities
of the same class as other securities for which a registration statement on this
form relating to an employee benefit plan is effective. Pursuant to General
Instruction E of Form S-8, this registration statement incorporates by reference
the following registration statements filed by Registrant on Form S-8:
Registration No. 333-40848, Registration No. 333-66457, Registration No.
333-66429, and Registration No. 333-07315, relating to an aggregate of 750,000
shares issuable under the Registrant's 1995 Employee Stock Purchase Plan.

(1)      Estimated solely for the purpose of determining the registration fee
         pursuant to Rule 457(h) under the Securities Act of 1933, on the basis
         of the average high and low prices for the Registrant's common stock on
         the Nasdaq National Market on May 7, 2002.

(2)      Such presently indeterminable number of additional shares of common
         stock are registered hereunder as may be issued in the event of a
         merger, consolidation, reorganization, recapitalization, stock
         dividend, stock split, stock combination, or other similar changes in
         the common stock.

(3)      On July 23, 1997, the Board of Directors of the Registrant declared a
         dividend of one preferred share purchase right for each share of common
         stock outstanding on August 21, 1997. The 750,000 rights registered by
         this Registration Statement represent one right that may be issued in
         connection with each share of common stock issuable upon exercise of
         options granted or to be granted under the Registrant's 1995 Employee
         Stock Purchase Plan. Such presently indeterminable number of rights are
         also registered by this Registration Statement as may be issued in the
         event of a merger, consolidation, reorganization, recapitalization,
         stock dividend, stock split or other similar change in common stock.
         The rights are not separately transferable apart from the common stock,
         nor are they exercisable until the occurrence of certain events.
         Accordingly, no independent value has been attributed to the rights.
