Item 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.
Reference is hereby made to the Form 8-A of Haggar Corp., a Nevada corporation
(the "Registrant"), filed with the Securities and Exchange Commission on
November 16, 1992, and amended as of December 2, 1992, and such Form 8-A, as
amended, is hereby incorporated by reference herein.
The Registrant executed an Amendment No. 1 (the "Amendment"), dated as of August
30, 2001, to the Rights Agreement, dated as of December 1, 1992 (the "Rights
Agreement"), between the Registrant and Mellon Investor Services, Inc., as
successor rights agent to Chemical Shareholder Services Group, Inc. (the "RIGHTS
AGENT"). Capitalized terms used herein and not otherwise defined shall have the
meanings ascribed to them in the Rights Agreement.
As more fully set forth in the Amendment, the Amendment reduces the threshold
required to become an "Acquiring Person" from twenty percent (20%) or more to
fifteen percent (15%) or more of the outstanding shares of common stock of the
Registrant under certain circumstances. In addition, the Amendment provides that
any person who holds 15% or more of the outstanding shares of common stock of
the Registrant as of the date of the Amendment will not become an "Acquiring
Person" unless such person acquires additional shares of common stock of the
Registrant after the date of the Amendment. The Amendment also removes all
references to the need for Continuing Director decision making, such decision
making now being vested in the Board of Directors.
A copy of the Amendment is attached hereto as Exhibit 1 and is incorporated
herein by reference. The foregoing discussion does not purport to be complete
and is qualified in its entirety by reference to Exhibit 1 attached hereto.
