MICROCHIP TECHNOLOGY INCORPORATED
  INTERNATIONAL EMPLOYEE STOCK PURCHASE PLAN
  AS AMENDED THROUGH AUGUST 20, 2004    
    

I.     PURPOSE  

        This International Employee Stock Purchase Plan is hereby established by Microchip Technology Incorporated, a Delaware corporation ("Microchip"), in order to
provide eligible employees of foreign Microchip subsidiaries with the opportunity to acquire a proprietary interest in Microchip through the purchase of shares of Microchip common stock at periodic
intervals with their accumulated payroll deductions. 

II.    DEFINITIONS  

        For purposes of administration of the Plan, the following terms shall have the meanings indicated: 

        Common Stock means shares of Microchip common stock, par value $0.001 per share. 

        Earnings means regular base salary plus such additional items of compensation as the Plan Administrator may deem appropriate. 

        Effective Date means June 1, 1994 for the Foreign Subsidiaries listed in attached Schedule A. For any other Foreign
Subsidiary, the effective date shall be determined by the Microchip Board of Directors or the Employee Committee of the Board of Directors, acting alone or in conjunction, prior to the time such
Foreign Subsidiary is to become a participating company in the Plan. 

        Eligible Employee means any non-U.S. citizen who is engaged, on a regularly-scheduled basis of more than twenty
(20) hours per week for more than five (5) months per calendar year, in the rendition of personal services outside the U.S. as an employee of a Foreign Subsidiary subject to the control
and direction of that Foreign Subsidiary as to both the work to be performed and the manner and method of performance. 

        Foreign Subsidiary means any non-U.S. Microchip subsidiary which elects, with the approval of the Microchip Board of Directors
or the Employee Committee of the Board of Directors, acting alone or in conjunction, to extend the benefits of this Plan to its Eligible Employees. As of the Effective Date, the Foreign Subsidiaries
participating in the Plan are listed on attached Schedule A. 

        Participant means any Eligible Employee of a Foreign Subsidiary who is actively participating in the Plan. 

        Service means the period during which an individual performs services as an Eligible Employee and shall be measured from his or her hire
date, whether that date is before or after the Effective Date of the Plan. 

III.  ADMINISTRATION  

        Each Foreign Subsidiary shall have responsibility for the administration of the Plan with respect to its Eligible Employees. Accordingly, the Plan shall, as to
each Foreign Subsidiary, be separately administered by a plan administrator comprised of two or more Members of the Board of Directors, the Employee Committee of the Board of Directors, or a designee
as may be appointed by either of them from time to time ("Plan Administrator"). The Plan Administrator shall have full authority to administer the Plan, including authority to interpret and construe
any provision of the Plan and to adopt such rules and regulations for administering the Plan as it may deem necessary. Decisions of the Plan Administrator shall be subject to ratification by the
Microchip Board of Directors and, when so ratified, shall be final and binding on all parties who have an interest in the Plan. 

 

IV.    PURCHASE PERIODS  

        A.    Shares
of Common Stock shall be offered for purchase under the Plan through a series of successive purchase periods until such time as (i) the maximum number of
shares of Common Stock available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated in accordance with Article VIII. 

        B.    The
Plan shall be implemented in a series of successive purchase periods, each to be of a duration of six (6) months. The initial purchase period will begin on
June 1, 1994 and end on the last U.S. business day in November 1994. Subsequent purchase periods shall, for so long as the Plan remains in existence, run from the first U.S. business day
of December to the last U.S. business day of May and from the first U.S. business day of June to the last U.S. business day of November. 

        C.    No
purchase period shall commence under the Plan, nor shall any shares of Common Stock be issued hereunder, until such time as (i) the Plan shall have been
approved by the Microchip Board of Directors and (ii) Microchip shall have complied with all applicable requirements of the Securities Act of 1933 (as amended), all applicable listing
requirements of any securities exchange on which shares of the Common Stock are listed and all other applicable statutory and regulatory requirements. 

        D.    The
Participant shall be granted a separate purchase right for each purchase period in which he/she participates. The purchase right shall be granted on the start date of
the purchase period and shall be automatically exercised on the last U.S. business day of that purchase period. 

        E.    The
acquisition of Common Stock through plan participation for any purchase period shall neither limit nor require the acquisition of Common Stock by the Participant in
any subsequent purchase period. 

V.     ELIGIBILITY AND PARTICIPATION  

        A.    Each
Eligible Employee of each Foreign Subsidiary participating in the Plan may join the Plan in accordance with the following provisions: 

        —    An
individual who is an Eligible Employee with at least thirty (30) days of Service prior to the start date of the purchase period may enter that
purchase period on such start date, provided he/she enrolls in the purchase period on or before such date in accordance with Section V.B below. Should any such Eligible Employee not enter the
purchase period on the start date, then he/she may not subsequently join that particular purchase period on any later date. 

        —    An
individual who is an Eligible Employee with less than thirty (30) days of Service on the start date of the purchase period may not participate in
that purchase period but will be eligible to join the Plan on the start date of the first purchase period thereafter on which he/she is an Eligible Employee with at least thirty (30) days of
Service. 

        B.    To
participate for a particular purchase period, the Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a purchase
agreement and a payroll deduction authorization) and file such forms with the Plan Administrator (or its designate) on or before the start date of that purchase period. 

        C.    The
payroll deduction authorized by the Participant shall be collected under the Plan in the currency in which paid by the Foreign Subsidiary and may be any multiple of
one percent (1%) of the Earnings paid to the Participant during each purchase period, up to a maximum of ten percent (10%). Any changes or fluctuations in the exchange rate at which the currency
collected from the Participant through such payroll deductions is converted into U.S. Dollars on each purchase date under the Plan shall be borne solely by the Participant. The deduction rate so
authorized shall continue in effect for 

2

 

the
entire purchase period and for each successive purchase period, except to the extent such rate is changed in accordance with the following guidelines: 

        —    The
Participant may, at any time during the purchase period, reduce his/her rate of payroll deduction. Such reduction shall become effective as soon as
possible after filing of the requisite reduction form with the Plan Administrator (or its designate), but the Participant may not effect more than one such reduction during the same purchase period. 

        —    The
Participant may, prior to the start date of any subsequent purchase period, increase or decrease the rate of his/her payroll deduction by filing the
appropriate form with the Plan Administrator (or its designate). The new rate (which may not exceed the ten percent (10%) maximum) shall become effective as of the start date of the new six (6)-month
purchase period. 

        Payroll
deductions will automatically cease upon the termination of the Participant's purchase right in accordance with the applicable provisions of Section VII below. 

VI.   STOCK SUBJECT TO PLAN  

        A.    The
Common Stock purchasable under the Plan shall, solely in the discretion of the Microchip Board, be made available from authorized but unissued shares of Common Stock
or from shares of Common Stock reacquired by Microchip, including shares of Common Stock purchased on the open market. The total number of shares which may be issued under the Plan shall not exceed
348,5931 shares. 

	1
	Adjusted
to reflect: (i) the three-for-two stock split of the outstanding Common Stock effected in November 1994; (ii) the three-for-two stock split of the outstanding
Common Stock effected in January 1997, (iii) the 10,000 share increase authorized by the Board of Directors on April 25 1997, (iv) the three-for-two stock split of the outstanding Common Stock
effected in January 2000, (v) the three-for-two stock split of the outstanding Common Stock effected in September 2000, (vi) the three-for-two stock split of the outstanding Common Stock effected in
May 2002 (vii) the 25,000 share increase authorized by the Board of Directors on March 3, 2003 and (viii) the 100,000 share increase authorized by the Board of Directors on August 20, 2004. 

        B.    In
the event any change is made to the outstanding Common Stock by reason of any stock dividend, stock split, combination of shares or other change affecting such
outstanding Common Stock as a class without Microchip's receipt of consideration, appropriate adjustments shall be made by the Microchip Board of Directors to (i) the class and maximum number
of securities issuable over the term of the Plan, (ii) the class and maximum number of securities purchasable per Participant during any one purchase period and (iii) the class and
number of securities and the price per share in effect under each purchase right at the time outstanding under the Plan. Such adjustments shall be designed to preclude the dilution or enlargement of
rights and benefits under the Plan. 

VII. PURCHASE RIGHTS  

        An Eligible Employee who participates in the Plan for a particular purchase period shall have the right to purchase shares of Common Stock upon the terms and
conditions set forth below and shall execute a purchase agreement incorporating such terms and conditions and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem
advisable. 

        Purchase Price.    Common Stock shall be issuable at the end of each purchase period at a purchase price equal to one hundred
percent (100%) of the lower of (i) the fair market value per share on the start date of that purchase period or (ii) the fair market value
per share on the last U.S. business day of that purchase period. 

3

 

        Valuation.    The fair market value per share of Common Stock on any relevant date under the Plan shall be the closing selling
price per share of Common Stock on that date, as officially quoted on the Nasdaq National Market. If there is no quoted selling price for such date, then the closing selling price per share of Common
Stock on the next preceding day for which there does exist such a quotation shall be determinative of fair market value. 

        Number of Purchasable Shares.    The number of shares purchasable per Participant during each purchase period shall be
determined as follows: first, the payroll deductions in the currency in which collected from the Participant during that purchase period shall be converted into U.S. Dollars on the last U.S. business
day of the purchase period at the exchange rate in effect on that day; then, the U.S. Dollar amount calculated for the Participant on the basis of such exchange rate shall be divided by the purchase
price in effect for such period to determine the number of whole shares of Common Stock purchasable on the Participant's behalf for that purchase period. However, no Participant may, during any one
purchase period, purchase more one thousand eight hundred ninety-nine (1,899) shares of Common Stock. 

        Payment.    Payment for the Common Stock purchased under the Plan shall be effected by means of the Participant's authorized
payroll deductions in the currency in which paid by the Foreign Subsidiary. Such deductions shall begin with the first full payroll period beginning with or immediately following the start date of the
purchase period and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of such purchase period. The amounts so collected
shall be credited to the Participant's book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account. The amounts collected from a Participant
may be commingled with the general assets of the Foreign Subsidiary or Microchip and may be used for general corporate purposes. However, all purchases of Common Stock under the
Plan shall be made in U.S. Dollars on the basis of the exchange rate in effect on the last day of each purchase period. 

        Termination of Purchase Right.    The following provisions shall govern the termination of outstanding purchase rights: 

        —    A
Participant may, at any time prior to the last seven (7) business days of the Foreign Subsidiary falling within the purchase period, terminate his/her
outstanding purchase right by filing the prescribed notification form with the Plan Administrator. No further payroll deductions shall be collected from the Participant with respect to the terminated
purchase right, and any payroll deductions collected for the purchase period in which such termination occurs shall, at the Participant's election, be immediately refunded in the currency in which
paid by the Foreign Subsidiary or held for the purchase of shares at the end of such purchase period. If no such election is made at the time the termination notice is filed, then the Participant's
payroll deductions shall be refunded as soon as possible after the termination date of his/her purchase right. 

        —    The
termination of such purchase right shall be irrevocable, and the Participant may not subsequently rejoin the purchase period for which the terminated
purchase right was granted. In order to resume participation in any subsequent purchase period, such individual must re-enroll in the Plan (by making a timely filing of a new purchase
agreement and payroll deduction authorization) on or before the date he/she is first eligible to join the new purchase period. 

        —    If
the Participant ceases to remain an Eligible Employee while his/her purchase right is outstanding, then such purchase right shall immediately terminate, and
the payroll deductions collected from such Participant for the purchase period shall be promptly refunded in the currency in which paid by the Foreign Subsidiary to the Participant. However, should
the Participant's cessation of Eligible Employee status occur by reason of death or permanent disability, then such 

4

 

individual
(or the personal representative of a deceased Participant) shall have the following election, exercisable up until the last day of the purchase period: 

        —    to
withdraw all of the Participant's payroll deductions for such purchase period, in the currency in which paid by the Foreign Subsidiary, or 

        —    to
have such funds held for the purchase of shares at the end of the purchase period. 

        If
no such election is made, then such funds shall be refunded as soon as possible after the end of the purchase period. In no event, however, may any payroll deductions be made on the
Participant's behalf following his/her cessation of Eligible Employee status. 

        Stock Purchase.    Shares of Common Stock shall automatically be purchased on behalf of each Participant (other than
Participants whose payroll deductions have previously been refunded in accordance with the Termination of Purchase Right provisions above) on the last U.S. business day of each purchase period. The
purchase shall be effected as follows: first, each Participant's payroll deductions for that purchase period (together with any carryover deductions from the preceding purchase period) shall be
converted from the currency in which paid by the Foreign Subsidiary into U.S. Dollars at the exchange rate in effect on the purchase date, and then the amount of U.S. Dollars calculated for each
Participant on the basis of such exchange rate shall be applied to the purchase of whole shares of Common Stock (subject to the limitation on the maximum number of purchasable shares set forth above)
at the purchase price in effect for such purchase period. Any payroll deductions not applied to such purchase because they are not sufficient to purchase a whole share shall be held for the purchase
of Common Stock in the next purchase period. However, any payroll deductions not applied to the purchase of Common Stock by reason of the limitation on the maximum number of shares purchasable by the
Participant during the purchase period shall be promptly refunded to the Participant in the currency in which paid by the Foreign Subsidiary. 

        Proration of Purchase Rights.    Should the total number of shares of Common Stock which are to be purchased pursuant to
outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Stock
pro-rated to such individual, shall be refunded to such Participant in the currency in which paid by the Foreign Subsidiary. 

        Rights as Stockholder.    A Participant shall have no stockholder rights with respect to the shares subject to his/her
outstanding purchase right until the shares are actually purchased on the Participant's behalf in accordance with the applicable provisions of the Plan. No adjustments shall be made for dividends,
distributions or other rights for which the record date is prior to the date of such purchase. 

        A
Participant shall be entitled to receive, as soon as practicable after the end of each purchase period, a stock certificate for the number of shares purchased on the Participant's
behalf. Such certificate may, upon the Participant's request, be issued in the names of the Participant and his/her spouse or may be issued in "street name" for immediate deposit in a designated
brokerage account. 

        Assignability.    No purchase right granted under the Plan shall be assignable or transferable by the Participant other than by
will or by the laws of descent and distribution following the Participant's death, and during the Participant's lifetime the purchase right shall be exercisable only by the Participant. 

5

 

        Change in Ownership.    Should any of the following transactions (a "Corporate Transaction") occur during the purchase period: 

        (i)    a
merger or other reorganization in which Microchip will not be the surviving corporation (other than a reorganization effected primarily to change the State in which
Microchip is incorporated), or 

        (ii)   a
sale of all or substantially all of Microchip's assets in liquidation or dissolution of Microchip, or 

        (iii)  a
reverse merger in which Microchip is the surviving corporation but in which more than 50% of Microchip's outstanding voting stock is transferred to person or persons
different from those who held the stock immediately prior to such merger, 

        then
all outstanding purchase rights under the Plan shall automatically be exercised immediately prior to the effective date of such Corporate Transaction by applying the payroll
deductions of each Participant for the purchase period in which such Corporate Transaction occurs to the purchase of whole shares of Common Stock at one hundred percent (100%) of the  lower of
(i) the fair market value of the Common Stock on the start date of the purchase period in which such Corporate Transaction occurs or
(ii) the fair market value of the Common Stock immediately prior to the effective date of such Corporate Transaction. Payroll deductions shall be converted from the currency in which paid by
the Foreign Subsidiary into U.S. Dollars on the basis of the exchange rate in effect on the purchase date, and the applicable share limitation of Article VII shall continue to apply to each
such purchase. Should Microchip sell or otherwise dispose of its ownership interest in any Foreign Subsidiary participating in the Plan, whether through merger or sale of all or substantially all of
the assets or outstanding capital stock of that Foreign Subsidiary, then a similar exercise of outstanding purchase rights shall be effected immediately prior to the effective date of such
disposition, but only to the extent those purchase rights are attributable to the employees of such Foreign Subsidiary. 

        Microchip
shall use its best efforts to provide at least ten (10)-days advance written notice of the occurrence of any such Corporate Transaction, and the Participants shall,
following the receipt of such notice, have the right to terminate their outstanding purchase rights in accordance with the applicable provisions of this Article VII. 

VIII. AMENDMENT AND TERMINATION  

        A.    The
Microchip Board of Directors may alter, amend, suspend or discontinue the Plan with respect to one or more Foreign Subsidiaries following the end of any purchase
period. The Microchip Board may also terminate the Plan in its entirety immediately following the end of any purchase period. In such event, no further purchase rights shall thereafter be granted or
exercised, and no further payroll deductions shall thereafter be collected, under the Plan. 

IX.   GENERAL PROVISIONS  

        A.    The
Plan shall become effective on the designated effective date for each Foreign Subsidiary, provided Microchip shall
have complied with all applicable requirements of the Securities Act of 1933 (as amended), all applicable listing requirements of any securities exchange on which shares of the Common Stock are listed
and all other applicable requirements established by law or regulation. 

        B.    The
Plan shall terminate upon the earlier of (i) the last U.S. business day in November 2014 or
(ii) the date on which all shares available for issuance under the Plan shall have been sold pursuant to purchase rights exercised under the Plan. 

        C.    All
costs and expenses incurred in the administration of the Plan shall be paid by the Foreign Subsidiary. 

6

 

        D.    Neither
the action of Microchip or the Foreign Subsidiary in establishing the Plan, nor any action taken under the Plan by the Microchip Board or the Plan Administrator,
nor any provision of the Plan itself shall be construed so as to grant any person the right to remain in the employ of the Foreign Subsidiary for any period of specific duration, and such person's
employment may be terminated at any time, with or without cause.

Exhibit 4.2  

 
 

MICROCHIP TECHNOLOGY INCORPORATED
  INTERNATIONAL STOCK PURCHASE AGREEMENT    
    

        I hereby elect to participate in the International Employee Stock Purchase Plan (the "IESPP") until such time as I elect to withdraw from the IESPP either by
written notification to the Stock Administrator or until termination of the Plan by the Company, and I hereby subscribe to purchase shares of common stock of Microchip Technology Incorporated ("Common
Stock") in accordance with the provisions of this Agreement and the IESPP. I hereby authorize payroll deductions from each of my paychecks during the time in which I participate in the IESPP in the 1%
multiple of my earnings (not to exceed a maximum of 10%) specified in my attached Enrollment Form. 

        I
understand that the Plan is a six-month offering period. The plans begins on the first business day of June and December of each year, and my participation will
automatically remain in effect from one offering period to the next offering period in accordance with my payroll deduction authorization, unless I withdraw from the IESPP or change the rate of my
payroll deduction or my employment status changes. 

        I
understand that my payroll deductions will be accumulated for the purchase of shares of Common Stock on the last business day of each offering period of participation. The purchase
price per share will be equal to 100% of the lower of (i) the fair market value per share of Common Stock on my entry date into the
six-month offering period or (ii) the fair market value per share on the purchase date. 

        I
understand that I can withdraw from the IESPP at any time prior to the last 5 business days of a period of participation and elect either to have the Company refund all my payroll
deductions for that period or to have such payroll deductions applied to the purchase of Common Stock at the end of such period. However, I may not rejoin that particular six-month
offering period at any later date. Upon my termination of employment or change to ineligible employee status, my participation in the IESPP will immediately cease and all my payroll deductions for the
six-month period in which such termination or change occurs will be refunded. Should I die or become disabled while an IESPP participant, payroll deductions will automatically cease on my
behalf, and I or my estate may, at any time prior to the last 5 business days of the semi-annual period in which I die or become disabled, elect to have my payroll deductions for that
period applied to the purchase of Common Stock at the end of that period; otherwise, those deductions will be refunded. I further understand that I may reduce my rate of my payroll deductions on one
occasion during a
six-month offering period, but that I may only increase my rate of payroll deductions at the beginning of a new six-month offering period. 

        I
understand that my shares will be placed in a brokerage account at the end of each six-month offering period of participation. The account will be opened in the
participant's name. 

        I
understand that the Company has the right, exercisable in its sole discretion, to amend or terminate the IESPP at any time, with such amendment or termination to become effective
immediately following the exercise of outstanding purchase rights at the end of any current six-month period of participation. Should the Company elect to terminate the IESPP, I will have
no further rights to purchase shares of Common Stock pursuant to this Agreement. 

        I
understand that the IESPP sets forth restrictions (i) limiting the maximum number of shares which I may purchase per the six-month period of participation and
(ii) prohibiting me from purchasing more than $25,000 worth of Common Stock per calendar year. 

        I
acknowledge that I have received a copy of the official Plan Prospectus summarizing the operation of the IESPP. I have read this Agreement and the Prospectus and hereby agree to be
bound by the terms of both this Agreement and the IESPP. The effectiveness of this Agreement is dependent upon my eligibility to participate in the IESPP.
