Entry
          into a Material Definitive Agreement
On
        January 29, 2007, the Board of Directors of Microchip Technology Incorporated
        (the "Company") approved an amendment to that certain Amended and Restated
        Preferred Shares Rights Agreement dated as of October 11, 1999 between the
        Company and Norwest Bank Minnesota, N.A. (the "Rights Agreement"). The purpose
        of the amendment was to change the definition of "Acquiring Person" in the

        definition from 15% to 18%. This amendment was not in response to any proposal
        to acquire control of the Company.
The
        text
        of the amendment will be filed as an exhibit to the Company's Annual Report on
        Form 10-K for the fiscal year ended March 31, 2007.
