                        ADDENDUM TO DEVELOPMENT AGREEMENT

                                    C2000-104
                                Original C97-141

     This Addendum to Development Agreement C97-141 is made the 11th day of May,
2000 by and between the City of Tempe, Arizona, an Arizona municipal corporation
("Tempe" or "City") and Microchip Technology Inc., a Delaware corporation
("Microchip").

RECITALS:

     A.   Microchip plans to increase its wastewater discharge by five hundred
          twenty three thousand (523,000) gallons per day (gpd) over the next
          two years, to a maximum discharge of 1.2 million gallons per day (mgd)
          by mid-year 2002.

     B.   The City's existing water distribution system can support the proposed
          increase in potable water demand at Microchip's site.

     C.   The City plans to provide sufficient treatment capacity, at cost, in
          the Plant IV-A expansion of the 91st Avenue Wastewater Treatment
          Plant, hereinafter "WWTP" to satisfy Microchip's projected demand.
          Tempe has determined the cost of additional transmission capacity
          needed to convey the wastewater to the 91st Avenue WWTP, and included
          that amount in Microchip's expansion costs.

     D.   The total cost estimate for both wastewater treatment in Plant IV-A of
          the 91st Avenue WWTP and transmission line rehabilitation is $5.08 per
          gallon. The total cost for 523,000 gpd of wastewater capacity is
          $2,656,840.00.

NOW, THEREFORE, in consideration of the mutual agreements set forth herein, it
is understood and agreed by Microchip and the City as follows:

1.   Microchip shall pay to City the nonrefundable sum of Two Million Six
     Hundred Fifty Six Thousand Eight Hundred Forty and no/100 Dollars
     ($2,656,840.00) for the additional wastewater treatment and transmission
     capacity needed.

2.   Tempe will not assess any other wastewater development fees for Microchip's
     current expansion, with the exception of any costs or charges associated
     with industrial pretreatment program requirements as enforced by its
     Environmental Services Division.

3.   The sum of $2,656,840.00 is due and payable from Microchip to the City
     within thirty (30) days after the City Council has approved this Addendum
     to Development Agreement C97-141.

4.   After Tempe receives the payment identified above, the City shall undertake
     all necessary measures during Microchip's ramping up of its wastewater
     discharge, and when the facility reaches full capacity of 1.2 mgd, to
     ensure full compliance with the terms and conditions of this Addendum.
     Microchip's projected wastewater discharge volumes total: 0.78 mgd in June
     2000, 1.01 mgd in January 2001, .95 mgd in June 2001, 1.02 mgd in January
     2002, and 1.2 mgd in June 2002. Tempe represents that it can accommodate
     the proposed discharge to the City's sanitary sewer system.

5.   All other terms and conditions of the original Development Agreement and
     the First Amendment thereto shall remain in full force and effect and shall
     not be modified by this Addendum.

6.   A copy of this Addendum to Development Agreement shall be recorded in the
     records of the Maricopa County Recorder within ten (10) days after the
     execution by the parties as required in paragraph 12.18 of the Development
     Agreement and State statute.
