    WHEREAS, the parties hereto desire to amend the
Rights Agreement in certain respects;

      NOW, THEREFORE, the parties hereto agree as
follows:

     Section 1.  Defined Terms; References.  (a)
Unless otherwise specifically defined herein, each term
used herein which is defined in the Rights Agreement
has the meaning assigned to such term in the Rights
Agreement.  Each reference to "hereof", "hereunder",
"herein" and "hereby" and each other similar reference
and each reference to "this Agreement" and each other
similar reference contained in the Rights Agreement
shall, after this Amendment becomes effective, refer to
the Rights Agreement as amended hereby.

    (b) Section 1 of the Rights Agreement is hereby
amended by deleting the definition of "Continuing
Directors" contained therein.

    (c) Section 1 of the Rights Agreement is hereby
amended by restating in its entirety the following
definition to read in full as follows:

          "Acquiring Person" means any Person who,
          together with all Affiliates and Associates
          of such Person, shall be the Beneficial Owner
          of 15% or more of the shares of Common Stock
          then outstanding, but shall not include the
          Company, any of its Subsidiaries, any
          employee benefit plan of the Company or any
          of its Subsidiaries or any Person organized,
          appointed or established by the Company or
          any of its Subsidiaries for or pursuant to
          the terms of any such plan; provided,
          however, that
          
                 (a)  if the majority of Directors
               determines (whether prior to or after
               the date that in the absence of such
               determination would be a Distribution
               Date) in good faith that a Person who
               otherwise would be an "Acquiring Person"
               became such inadvertently, and if such
               Person as


               promptly as practicable divests itself
               of Beneficial Ownership of a sufficient
               number of shares of Common Stock so that
               such Person is no longer an "Acquiring
               Person," then such Person shall not be
               deemed to be or to have become an
               "Acquiring Person" for any purposes of
               this Agreement; and
               
                    (b)   no Person shall become an
               "Acquiring Person" solely as a result of
               an acquisition of shares of Common Stock
               by the Company which, by reducing the
               number of shares of Common Stock
               outstanding, increases the proportionate
               number of shares of Common Stock
               beneficially owned by such Person
               (together with any Affiliate and
               Associate of such Person) to 15% or more
               of the shares of Common Stock then
               outstanding; provided, however, that if
               a Person shall become the Beneficial
               Owner of 15% or more of the shares of
               Common Stock then outstanding by reason
               of such share acquisition by the Company
               and shall thereafter (together with any
               Affiliate and Associate) become the
               Beneficial Owner of any additional
               shares of Common Stock (other than
               pursuant to a stock dividend, stock
               split, recapitalization or similar
               transaction that does not affect the
               percentage of outstanding Common Stock
               beneficially owned by such Person) which
               causes the proportionate number of
               shares of Common Stock beneficially
               owned by such Person to increase to 15%
               or more of the shares of Common Stock
               then outstanding, then such Person shall
               be deemed to be an "Acquiring Person".
