                  SECTION 1. AMENDMENT OF SECTION 1(A) OF THE RIGHTS AGREEMENT.
(a) Section 1(a) of the Rights Agreement is hereby amended to read in its
entirety as follows:

                           "(a) "ACQUIRING PERSON" shall mean (i) any Person,
         other than the State of Wisconsin Investment Board ("SWIB"), who or
         which, together with all Affiliates and Associates of such Person,
         shall be the Beneficial Owner of 15% or more of the Common Shares then
         outstanding, or (ii) SWIB on such date as it, together with all of its
         Affiliates and Associates, shall be the Beneficial Owner of 16.5% or
         more of the Common Shares then outstanding, but shall not include the
         Company, any Subsidiary of the Company or any employee benefit plan of
         the Company or of any Subsidiary of the Company, or any entity holding
         Common Shares for or pursuant to the terms of any such plan.
         Notwithstanding the foregoing, no Person shall be deemed to be an
         Acquiring Person as the result of an acquisition of Common Shares by
         the Company which, by reducing the number of shares outstanding,
         increases the proportionate number of shares beneficially owned by such
         Person to 15% or more (16.5% or more in the case of SWIB) of the Common
         Shares of the Company then outstanding; provided, however, that if a
         Person shall become the Beneficial Owner of 15% or more (16.5% or more
         in the case of SWIB) of the Common Shares of the Company then
         outstanding by reason of share purchases by the Company and shall,
         after such share purchases by the Company, become the Beneficial Owner
         of any additional Common Shares of the Company (other than pursuant to
         a dividend or distribution paid or made by the Company on the
         outstanding Common Shares in Common Shares or pursuant to a split or
         subdivision of the outstanding Common Shares), then such Person shall
         be deemed to be an Acquiring Person unless upon becoming the Beneficial
         Owner of such additional Common Shares of the Company

<PAGE>

         such Person does not beneficially own 15% or more (16.5% or more in the
         case of SWIB) of the Common Shares of the Company then outstanding.
         Notwithstanding the foregoing, (i) if the Company's Board of Directors
         determines in good faith that a Person who would otherwise be an
         "Acquiring Person," as defined pursuant to the foregoing provisions of
         this paragraph (a), has become such inadvertently (including, without
         limitation, because (A) such Person was unaware that it beneficially
         owned a percentage of the Common Shares that would otherwise cause such
         Person to be an "Acquiring Person, " as defined pursuant to the
         foregoing provisions of this paragraph (a), or (B) such Person was
         aware of the extent of the Common Shares it beneficially owned but had
         no actual knowledge of the consequences of such beneficial ownership
         under this Agreement) and without any intention of changing or
         influencing control of the Company, and if such Person divested or
         divests as promptly as practicable a sufficient number of Common Shares
         so that such Person would no longer be an "Acquiring Person," as
         defined pursuant to the foregoing provisions of this paragraph (a),
         then such Person shall not be deemed to be or to have become an
         "Acquiring Person" for any purposes of this Agreement; and (ii) if, as
         of the date hereof, any Person is the Beneficial Owner of 15% or more
         of the Common Shares outstanding, such Person shall not be or become an
         "Acquiring Person," as defined pursuant to the foregoing provisions of
         this paragraph (a), unless and until such time as such Person shall
         become the Beneficial Owner of additional Common Shares (other than
         pursuant to a dividend or distribution paid or made by the Company on
         the outstanding Common Shares in Common Shares or pursuant to a split
         or subdivision of the outstanding Common Shares), unless, upon becoming
         the Beneficial Owner of such additional Common Shares, such Person is
         not then the Beneficial Owner of 15% or more of the Common Shares then
         outstanding."

Benefits

You will also be entitled, during the term of your employment, to such
vacation, medical and other employee benefits as the Company may offer from
time to time, subject to applicable eligibility requirements. The Company does
reserve the right to make any modifications in this benefits package that it
deems appropriate. All employees receive pro-rated vacation and personal time.
Please refer to the enclosed benefits documents for more information. You

or representatives are superseded by this offer letter.

Confidentiality, Noncompetition and Invention Assignment Agreement

As a condition of your employment pursuant to this offer letter, we require

certain employment opportunities for a period of 18 months after you leave the
Company. Please review the agreement carefully and, if appropriate, have your
attorney review it as well.
