RESTATED AND AMENDED 1993 STOCK OPTION PLAN

Exhibit 10.1

MICROCHIP TECHNOLOGY INCORPORATED
1993 STOCK OPTION PLAN
AS RESTATED AND AMENDED THROUGH AUGUST 16, 2002

ARTICLE I
GENERAL

1.1 PURPOSE OF THE PLAN

(a) AMENDMENT. On January 19, 1993, the Board of Directors (the
"Board") of Microchip Technology Incorporated, a Delaware corporation (the
"Corporation") adopted the 1993 Stock Option/Stock Issuance Plan. On April 23,
1993 and September 14, 1993, the Board amended the Plan authorizing additional
available shares of Common Stock. On October 7, 1993, the Board amended and
restated the Plan as stated herein. On April 18, 1994, the Board amended the
Plan authorizing additional available shares of Common Stock, subject to
stockholder approval. On January 20, and April 26, 1995, the Board amended the
Plan authorizing, among other matters, additional available shares of Common
Stock, subject to stockholder approval and the elimination of the stock issuance
portion of the Plan. Any options outstanding under the Plan before this
amendment shall remain valid and unchanged. On April 25, 1997, the Board amended
the Plan authorizing, among other matters, additional available shares of Common
Stock, subject to stockholder approval. On August 18, 2000 the stockholders
approved an amendment to the Plan (which was adopted by the Board on May 5,
2000) to extend its term as set forth in Section 5.3(d) hereof. The Board also
amended the Plan to provide that, following the approval by the stockholders of
the extension of the term of the Plan, Incentive Options could no longer be
granted (see Section 2.2(e)). On October 26, 2001, the Board amended the Plan to
permit the payment of the option exercise price by delivering shares of Common
Stock. On February 11, 2002, the Board amended the Plan to provide that options
granted on or after April 1, 2002 would vest in their entirety upon an
Optionee's death if the Optionee dies while in Service to the Company. On May 6,
2002, the Board amended the Plan to update it to reflect regulatory changes. On
August 16, 2002, the stockholders approved amendments to the Plan that had been
approved by the Board on May 6, 2002, to increase automatic grants under Article
IV and to provide for a special one-time option grant to non-employee directors.

(b) PURPOSE. This 1993 Stock Option Plan, amended through August 16,
2002 ("Plan"), is intended to promote the interests of the Corporation by
providing (i) key employees (including officers) of the Corporation (or its
parent or subsidiary corporations) who are responsible for the management,
growth and financial success of the Corporation (or its parent or subsidiary
corporations), (ii) non-employee members of the Corporation's Board of Directors
(the "Board") and (ii) consultants and other independent contractors who provide
valuable services to the Corporation (or its parent or subsidiary corporations)
the opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the corporation as an incentive for them to remain in
the service of the Corporation (or its parent or subsidiary corporations).
(c) EFFECTIVE DATE. The Plan became effective on the first date on
which the shares of the Corporation's common stock were registered under Section
12(g) of the Securities Exchange Act of 1934, as amended (the "1934 Act"). Such
date is hereby designated as the Effective Date of the Plan. The effective date
of any amendments to the Plan shall be as of the date of Board approval or such
other subsequent date as is specified by the Board. Notwithstanding the
foregoing, certain amendments referenced herein must be approved by the
stockholders of the Corporation.

(d) SUCCESSOR TO 1989 PLAN. This Plan shall serve as the successor to
the Corporation's 1989 Stock Option Plan (the "1989 Plan"), and no further
option grants or stock issuances shall be made under the 1989 Plan from and
after the Effective Date of this Plan. All options outstanding under the 1989
Plan on such Effective Date are hereby incorporated into this Plan and shall
accordingly be treated as outstanding options under this Plan. However, each
outstanding option so incorporated shall continue to be governed solely by the
express terms and conditions of the instrument evidencing such grant, and no
provision of this Plan shall be deemed to affect or otherwise modify the rights
or obligations of the holders of such incorporated options with respect to their
acquisition of shares of the Corporation's common stock thereunder. All
outstanding unvested share issuances under the 1989 Plan shall continue to be
governed solely by the express terms and conditions of the instruments
evidencing such issuances, and no provision of this Plan shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
unvested shares.

(e) PARENT/SUBSIDIARIES. For purposes of the Plan, the following
provisions shall be applicable in determining the parent and subsidiary
corporations of the Corporation:

(i) Any corporation (other than the Corporation) in an unbroken
chain of corporations ending with the Corporation shall be considered to be a
parent of the corporation, provided each such corporation in the unbroken chain
(other than the Corporation) owns, at the time of the determination, stock
possessing fifty percent (50%) or more of the total combined voting power of all
classes of stock in any other corporation in such chain.

(ii) Each corporation (other than the Corporation) in an unbroken
chain of corporations beginning with the Corporation shall be considered to be a
subsidiary of the Corporation, provided each such corporation (other than the
last corporation) in the unbroken chain owns, at the time of the determination,
stock possessing fifty percent (50%) or more of the total combined voting power
of all classes of stock in any other corporation in such chain.

(f) All references herein to number of shares of Common Stock have
been restated to reflect a 2-for-1 stock split of the Common Stock effected on
September 14, 1993, a 3-for-2 stock split of the Common Stock effected on April
4, 1994, a 3-for-2 split of the Common Stock effected on November 8, 1994, a
3-for-2 split of the Common Stock effected on January 6, 1997, a 3-for-2 split
of the Common Stock effected on February 7, 2000, a 3-for-2 split of the Common
Stock effected on September 26, 2001 and a 3-for-2 split effected on May 8,
2002.

1.2 STRUCTURE OF THE PLAN

(a) STOCK PROGRAMS. The Plan shall be divided into two separate
components: the Discretionary Option Grant Program specified in Article II and
the Automatic Option Grant Program specified in Article IV. Under the
Discretionary Option Grant Program, eligible individuals may, at the discretion
of the Plan Administrator, be granted options to purchase shares of Common Stock
in accordance with the provisions of Article II. Under the Automatic Option
Grant Program, non-employee members of the Board will be automatically granted
options to purchase shares of the Common Stock in accordance with the provisions
of Article IV.

(b) GENERAL PROVISIONS. Unless the context clearly indicates
otherwise, the provisions of Articles I and V shall apply to the Discretionary
Option Grant Program and the Automatic Stock Grant Program, and shall
accordingly govern the interests of all individuals under the Plan.

1.3 ADMINISTRATION OF THE PLAN

(a) BIFURCATION OF ADMINISTRATION. The eligible persons under the
Discretionary Option Grant Program shall be divided into two groups and there
shall be a separate administrator for each group. One group shall be comprised
of eligible persons that are "Affiliates." For purposes of the Plan, the term
"Affiliates" shall mean (i) all "executive officers" as that term is defined in
Rule 16a-1(f) promulgated under the Securities and Exchange Act of 1934 as
amended (the "1934 Act"), and (ii) all directors of the Company. The other group
shall be comprised of all eligible persons under the Plan that are not
Affiliates ("Non-Affiliates").

(b) AFFILIATE ADMINISTRATION. The power to administer the
Discretionary Option Grant Program with respect to eligible persons that are
Affiliates shall be vested with a committee (the "Senior Committee") of two (2)
or more non-employee Board members appointed by the Board. No Board member shall
be eligible to serve on the Senior Committee unless such individual qualifies as
both (i) an outside director as defined in Internal Revenue Code Section 162(m)
and the regulations promulgated thereunder, and (ii) a non-employee director as
defined in Rule 16b-3 promulgated under the 1934 Act.

(c) NON-AFFILIATE ADMINISTRATION. The power to administer the
Discretionary Option Grant Program with respect to eligible persons that are not
Non-Affiliates shall be vested with the Board. The Board, however, may at any
time appoint a committee (the "Employee Committee") of one or more persons who
are members of the Board or members of senior management of the Company and
delegate to such Employee Committee the power, in whole or in part, to
administer the Discretionary Stock Option Grant Program with respect to the
Non-Affiliates.

(d) TERM ON COMMITTEE. Members of the Senior Committee and the
Employee Committee shall serve for such period of time as the Board may
determine and shall be subject to removal by the Board at any time. The Board at
any time may terminate the functions of the Employee Committee and reassume all
powers and authority previously delegated to such Committee.

3
(e) AUTHORITY OF PLAN ADMINISTRATORS. The Board, the Employee
Committee, and the Senior Committee, whichever is applicable, shall each be
referred to herein as a "Plan Administrator." Each Plan Administrator shall have
the authority and discretion, with respect to its administered group, to select
which eligible persons shall participate in the Plan. Unless otherwise required
by law, decisions among members of a Plan Administrator shall be by majority
vote. With respect to each administered group, the applicable Plan Administrator
shall have full power and authority (subject to the express provisions of the
Plan) to establish such rules and regulations as it may deem appropriate for the
proper administration of the Discretionary Option Grant Program and to make such
determinations under, and issue such interpretations of, the provisions of such
programs and any outstanding option grants or stock issuances thereunder as it
may deem necessary or advisable. All decisions made by a Plan Administrator
shall be final and binding on all parties in its administered group who have an
interest in the Discretionary Option Grant Program or any outstanding option
thereunder. The Plan Administrator shall also have full authority to determine,
with respect to the option grants made under the Discretionary Option Program,
the number of shares to be covered by each such grant, the time or times at
which each granted option is to become exercisable and the maximum term for
which the option may remain outstanding.

(f) INDEMNIFICATION. In addition to such other rights of
indemnification as they may have, the members of each Plan Administrator shall
be indemnified and held harmless by the Company, to the extent permitted under
applicable law, for, from and against all costs and expenses reasonably incurred
by them in connection with any action, legal proceeding to which any such member
thereof may be a party, by reason of any action taken or failed to be taken,
under or in connection with the Plan or any rights granted thereunder, and
against all amounts paid by them in settlement thereof or paid by them in
satisfaction of a judgment of any such action, suit or proceeding, except a
judgment based upon a finding of bad faith.

1.4 ELIGIBLE PERSONS UNDER THE PLAN

(a) DISCRETIONARY OPTION GRANT PROGRAM. The persons eligible to
participate in the Discretionary Option Grant Program under Article II are as
follows:

(i) officers and other key employees of the Corporation (or its
parent or subsidiary corporations) who render services which contribute to the
management, growth and financial success of the Corporation (or its parent or
subsidiary corporations);

(ii) non-employee members of the Board (excluding those current
members of the Senior Committee); and

(iii) those consultants or other independent contractors who
provide valuable services to the Corporation (or its parent or subsidiary
corporations).

Notwithstanding Section 1.4(a)(ii) above, all non-employee members of
the Board, including those current members of the Senior Committee, shall be

4
eligible for a one-time grant under the Discretionary Option Grant Program which
shall be the grant of an option to acquire 3,000 shares of Common Stock granted
as of the date on which the stockholders of the Corporation approve this
amendment at the Corporation's 2002 Annual Stockholders' Meeting, and the
exercise price of which shall be equal to 100% of the fair market value per
share of the Common Stock on such date, as determined in accordance with the
valuation provisions of Section 2.1(d) hereof, and that shall vest as follows:
1,000 shares shall vest 12 months from the grant date and the remaining 2,000
shares shall vest ratably in 24 monthly installments commencing 12 months from
the grant date, subject to continued service on the Board as of such vesting
dates.

(b) AUTOMATIC OPTION GRANT PROGRAM. The persons eligible to
participate in the Automatic Option Grant Program shall be limited to
non-employee Board members. A non-employee Board member shall not be eligible to
participate in the Automatic Option Grant Program, however, if such individual
has at any time been in the prior employ of the Corporation (or any parent or
subsidiary corporation). Unless otherwise provided in the Plan, persons who are
eligible under the Automatic Option Grant Program may also be eligible to
receive option grants under the Discretionary Option Grant Program in effect
under this Plan.

1.5 STOCK SUBJECT TO THE PLAN(1)

(a) AMENDMENT. Under the Plan, 20,493,766 shares were originally
authorized to be issued under the Plan (constituting 18,785,173 authorized
shares under the 1989 Plan and rolled over into this Plan plus 1,708,593
additional shares authorized by the Board on January 19, 1993). On April 23,
1993, an additional 7,403,906 shares were authorized by the Board, subject to
stockholder approval at the next stockholders' meeting. At that point, the total
available authorized shares was 27,897,672. On September 14, 1993, the Board
authorized the number of shares of Common Stock issuable under the Plan to be
increased by 7,700,062 shares. On April 18, 1994, the Board authorized the
number of shares of Common Stock issuable under the Plan to be increased by
9,871,875 shares. On January 20, 1995 and April 25, 1997, the Board authorized
the number of shares of Common Stock issuable under the Plan to be increased by
4,809,375 and 6,750,000 shares, respectively, subject to Stockholder approval,
such that the maximum number of shares issuable for the term of the Plan shall
be as set forth in Section 1.5(b) below.

(b) AVAILABLE SHARES. Shares of the Corporation's common stock (the
"Common Stock") shall be available for issuance under the Plan and shall be
drawn from either the Corporation's authorized but unissued shares of Common
Stock or from reacquired shares of Common Stock, including shares repurchased by
the Corporation on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed 57,028,984
shares, subject to adjustment from time to time in accordance with the
provisions of this Section 1.5. To the extent one or more outstanding options
under the 1989 Plan which have been incorporated into this Plan (as adjusted for
the 1993 Stock Dividend) are subsequently exercised, the number of shares issued

- ----------
(1) All numbers in Sections 1.5(a), 1.5(b) and 1.5(e) are adjusted for stock
splits which have occurred through May 2002.

5
with respect to each such option shall reduce, on a share-for-share basis, the
number of shares available for issuance under this Plan.

(c) ADJUSTMENTS FOR ISSUANCES. Should one or more outstanding options
under this Plan (including outstanding options under the 1989 Plan incorporated
into this Plan) expire or terminate for any reason prior to exercise in full,
then the shares subject to the portion of each option not so exercised shall be
available for subsequent option grant under the Plan. All share issuances under
the Plan, whether or not the shares are subsequently repurchased by the
Corporation pursuant to its repurchase rights under the Plan, shall reduce on a
share-for-share basis the number of shares of Common Stock available for
subsequent option grants under the Plan. In addition, should the exercise price
of an outstanding option under the Plan (including any option incorporated from
the 1989 Plan) be paid with shares of Common Stock or should shares of Common
Stock otherwise issuable under the Plan be withheld by the Corporation in
satisfaction of the withholding taxes incurred in connection with the exercise
of an outstanding option under the Plan, then the number of shares of Common
Stock available for issuance under the Plan shall be reduced by the gross number
of shares for which the option is exercised, and not by the net number of shares
of Common Stock actually issued to the option holder.

(d) ADJUSTMENTS FOR ORGANIC CHANGES. Should any change be made to the
Common Stock issuable under the Plan by reason of any stock split, stock
dividend, recapitalization, combination of shares, exchange of shares or other
change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration, then appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities and price per share in effect
under each option outstanding under either the Discretionary Option Grant
Program or the Automatic Option Grant Program and (iii) the number and/or class
of securities and price per share in effect under each outstanding option
incorporated into this Plan from the 1989 Plan. Such adjustments to the
outstanding options are to be effected in a manner which shall preclude the
enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Board shall be final, binding and conclusive. The
amount of options granted automatically under the Automatic Option Grant Program
on the Annual Automatic Grant Date and on the Initial Automatic Grant Date shall
not be adjusted regardless of any organic changes made to the Common Stock
issuable under the Plan.

(e) LIMITATIONS ON GRANTS TO EMPLOYEES. Notwithstanding any other
provision herein to the contrary, the following limitations shall apply to
grants of options to Employees:

(i) No employee shall be granted, in any fiscal year of the
Corporation, options to purchase more than one million five hundred eighteen
thousand seven hundred and fifty (1,518,750) shares.

(ii) In connection with his or her initial employment, an
Employee may be granted options to purchase up to an additional two million five
hundred thirty-one thousand two hundred and fifty (2,531,250) shares which shall
not count against the limit set forth in subsection (i) above.

6
(iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Corporation's capitalization as described
in Section 1.5(d).

(iv) If an option is cancelled in the same fiscal year of the
Corporation in which such option was granted (other than in connection with a
transaction described in Section 1.5(d)), the cancelled option will be counted
against the limit set forth in Section 1.5(e)(i). For this purpose, if the
exercise price of an option is reduced, the transaction will be treated as a
cancellation of the option and the grant of a new option.

ARTICLE II
DISCRETIONARY OPTION GRANT PROGRAM

2.1 TERMS AND CONDITIONS OF OPTIONS

(a) GENERAL. Options granted to eligible persons ("Optionees")
pursuant to the Discretionary Option Grant Program set forth in this Article II
shall be authorized by action of the Plan Administrator. Each granted option
shall be evidenced by one or more instruments in the form approved by the Plan
Administrator; provided, however, that each such instrument shall comply with
the terms and conditions specified below.

(b) OPTION PRICE. The option price per share of the Common Stock
subject to an option hereunder shall in no event be less than one hundred
percent (100%) of the fair market value of such Common Stock on the grant date.

(c) PAYMENT OF OPTION PRICE. The option price shall become
immediately due upon exercise of the option and shall be payable in one of the
following alternative forms specified below:

(i) full payment in cash or check made payable to the
Corporation's order; or

(ii) full payment in shares of Common Stock held for the
requisite period necessary to avoid a charge to the Corporation's earnings for
financial reporting purposes and valued at fair market value on the Exercise
Date (as such term is defined below); or

(iii) full payment in a combination of shares of Common Stock
held for the requisite period necessary to avoid a charge to the Corporation's
earnings for financial reporting purposes and valued at fair market value on the
Exercise Date and cash or check drawn to the Corporation's order; or

7
(iv) full payment through a broker-dealer sale and remittance
procedure pursuant to which the Optionee (A) shall provide irrevocable written
instructions to a designated brokerage firm to effect the immediate sale of the
purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate option
price payable for the purchased shares plus all applicable Federal and State
income and employment taxes required to be withheld by the Corporation in
connection with such purchase and shall (B) provide written directives to the
Corporation to deliver the certificates for the purchased shares directly to
such brokerage firm in order to complete the sales transaction.

For purposes of this Section 2.1(c), the Exercise Date shall be the date on
which written notice of the option exercise is delivered to the Corporation.
Except to the extent the sale and remittance procedure is utilized in connection
with the exercise of the option, payment of the option price for the purchased
shares must accompany such notice.

(d) FAIR MARKET VALUE. If the Common Stock is traded on any
established stock exchange or a national market system, including without
limitation the Nasdaq National Market or the Nasdaq SmallCap Market, the fair
market value shall be the closing price per share on the date in question, as
such price is reported in the Wall Street Journal or such other source as the
Administrator deems reliable. If there is no reported closing selling price for
the Common Stock on the date in question, then the closing selling price on the
last preceding date for which such quotation exists shall be determinative of
fair market value

(e) TERM AND EXERCISE OF OPTIONS. Each option granted under this
Discretionary Option Grant Program shall be exercisable at such time or times
and during such period as is determined by the Plan Administrator and set forth
in the instrument evidencing the grant. No such option, however, shall have a
maximum term in excess of ten (10) years from the grant date. Except as
determined otherwise by the Administrator, during the lifetime of the Optionee,
the option shall be exercisable only by the Optionee and shall not be assignable
or transferable by the Optionee other than by will or by the laws of descent and
distribution following the Optionee's death.

(f) TERMINATION OF SERVICE. The following provisions shall govern the
exercise period applicable to any outstanding options held by the Optionee at
the time of cessation of Service or death:

(i) Should an Optionee cease Service for any reason (including
permanent disability as defined in Section 22(e)(3) of the Internal Revenue Code
but not including death) while holding one or more outstanding options under
this Article II, then none of those options shall (except to the extent
otherwise provided pursuant to Section 2.1(g) below) remain exercisable for more
than a ninety (90) day period (or such shorter or longer period determined by
the Plan Administrator and set forth in the instrument evidencing the grant, but
not to exceed twelve (12) months) measured from the date of such cessation of
Service.

8
(ii) Any option held by the Optionee under this Article II and
exercisable in whole or in part on the date of his or her death may be
subsequently exercised by the personal representative of the Optionee's estate
or by the person or persons to whom the option is transferred pursuant to the
Optionee's will or in accordance with the laws of descent and distribution. With
respect to options granted on or after April 1, 2002, all such unvested options
shall immediately vest upon Optionee's death if such Optionee's death occurs
while Optionee is in Service to the Company. Any exercise following Optionee's
death while Optionee is in Service to the Company, however, must occur prior to
the earlier of (x) six months following the date of Optionee's death or (y) the
specified expiration date of the option term. Upon the occurrence of the earlier
event, the option shall terminate and cease to be outstanding.

(iii) Under no circumstances, however, shall any such option be
exercisable after the specified expiration date of the option term.

(iv) During the applicable post-Service exercise period, the
option shall not be exercisable for more than the number of shares (if any) in
which the Optionee is vested at the time of his or her cessation of Service
(less any option shares subsequently purchased by the Optionee prior to death).
Upon the expiration of the limited post-Service exercise period or (if earlier)
upon the specified expiration date of the option term, each such option shall
terminate and cease to be outstanding with respect to any vested shares for
which the option has not otherwise been exercised. However, each outstanding
option shall immediately terminate and cease to be outstanding, at the time of
the Optionee's cessation of Service, with respect to any shares for which the
option is not otherwise at that time exercisable or in which the Optionee is not
otherwise at that time vested.

(v) Should (A) the Optionee's service be terminated for
misconduct (including, but not limited to, any act of dishonesty, willful
misconduct, fraud or embezzlement) or (B) the Optionee make any unauthorized use
or disclosure of confidential information or trade secrets of the Corporation or
its parent or subsidiary corporations, then in any such event all outstanding
options held by the Optionee under this Article II shall terminate immediately
and cease to be outstanding.

(g) DISCRETION TO ACCELERATE VESTING. The Plan Administrator shall
have complete discretion, exercisable either at the time the option is granted
or at any time while the option remains outstanding, to permit one or more
options held by the Optionee under this Article II to be exercised, during the
limited post-Service exercise period applicable under Section 2.1(f) above, not
only with respect to the number of vested shares of Common Stock for which each
such option is exercisable at the time of the Optionee's cessation of Service
but also with respect to one or more subsequent installments of vested shares
for which the option would otherwise have become exercisable had such cessation
of Service not occurred.

(h) DISCRETION TO EXTEND EXERCISE PERIOD. The Plan Administrator
shall also have full power and authority to extend the period of time for which
the option is to remain exercisable following the Optionee's cessation of
Service or death from the limited period in effect under Section 2.1(f) above to
such greater period of time as the Plan Administrator shall deem appropriate. In

9
no event, however, shall such option be exercisable after the specified
expiration date of the option term.

(i) DEFINITIONS. For purposes of the foregoing provisions of this
Section 2.1 (and for all other purposes under the Discretionary Option Grant
Program):

(i) The Optionee shall (except to the extent otherwise
specifically provided in the applicable stock option agreement) be deemed to
remain in SERVICE for so long as such individual renders services on a periodic
basis to the Corporation (or any parent or subsidiary corporation) in the
capacity of an Employee, a non-employee member of the Board or an independent
consultant or advisor.

(ii) The Optionee shall be considered to be an EMPLOYEE for so
long as he or she remains in the employ of the Corporation or one or more parent
or subsidiary corporations, subject to the control and direction of the employer
entity not only as to the work to be performed but also as to the manner and
method of performance.

(j) STOCKHOLDER RIGHTS. An Optionee shall have no stockholder rights
with respect to any shares covered by the option until such individual shall
have exercised the option and paid the option price for the purchased shares.

2.2 INCENTIVE OPTIONS

From and after August 18, 2000, no incentive stock options, as defined
in Section 422 of the Internal Revenue Code, shall be granted under the Plan.

2.3 CORPORATE TRANSACTIONS

(a) DEFINITION. For purposes of this Plan, any of the following
stockholder approved transactions to which the Corporation is a party shall be
considered a "Corporate Transaction":

(i) a merger or consolidation in which the corporation is not
the surviving entity, except for a transaction the principal purpose of which is
to change the State in which the Corporation is incorporated,

(ii) the sale, transfer or other disposition of all or
substantially all of the assets of the Corporation in complete liquidation or
dissolution of the Corporation, or

(iii) any reverse merger in which the Corporation is the
surviving entity but in which securities possessing more than fifty percent
(50%) of the total combined voting power of the Corporation's outstanding
securities are transferred to person or persons different from those who held
such securities immediately prior to such merger.

(b) ACCELERATION OF OPTION. Upon the stockholder approval of a
Corporate Transaction, each option which is at the time outstanding under this
Article II shall automatically accelerate so that each such option shall,

10
immediately prior to the specified effective date for the Corporate Transaction,
become fully exercisable with respect to the total number of shares of Common
Stock at the time subject to such option and may be exercised for all or any
portion of such shares. However, an outstanding option under this Article II
shall not so accelerate if and to the extent: (A) such option is, in connection
with the Corporate Transaction, either to be assumed by the successor
corporation or parent thereof or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation or parent
thereof, (B) such option is to be replaced with a cash incentive program of the
successor corporation which preserves the option spread existing at the time of
the Corporate Transaction and provides for subsequent payout in accordance with
the same vesting schedule applicable to such option, or (C) the acceleration of
such option is subject to other limitations imposed by the Plan Administrator at
the time of the option grant. The determination of option comparability under
clause (A) above shall be made by the Plan Administrator, and its determination
shall be final, binding and conclusive.

(c) TERMINATION OF OPTIONS. Upon the consummation of the Corporate
Transaction, all outstanding options under this Article II shall terminate and
cease to be outstanding, except to the extent assumed by the successor
corporation or its parent company.

(d) ADJUSTMENTS ON ASSUMPTION OR CONTINUATION. Each outstanding
option under this Article II which is assumed in connection with the Corporate
Transaction or is otherwise to continue in effect shall be appropriately
adjusted, immediately after such Corporate Transaction, to apply and pertain to
the number and class of securities which would have been issued to the option
holder, in consummation of such Corporate Transaction, had such person exercised
the option immediately prior to such Corporate Transaction. Appropriate
adjustments shall also be made to the option price payable per share, provided
the aggregate option price payable for such securities shall remain the same. In
addition, the class and number of securities available for issuance under the
Plan following the consummation of the Corporate Transaction shall be
appropriately adjusted.

(e) DISCRETION TO ACCELERATE. The Plan Administrator shall have the
discretion, exercisable either in advance of any actually-anticipated Corporate
Transaction or at the time of an actual Corporate Transaction, to provide (upon
such terms as it may deem appropriate) for the automatic acceleration of one or
more outstanding options granted under the Plan which are assumed or replaced in
the Corporate Transaction and do not otherwise accelerate at that time, in the
event the Optionee's Service should subsequently terminate within a designated
period following the effective date of such Corporate Transaction.

(f) PLAN NOT TO AFFECT CORPORATION. The grant of options under this
Article II shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

11
2.4 CHANGE IN CONTROL

(a) DEFINITION. For purposes of this Plan, a Change in Control shall
be deemed to occur in the event:

(i) any person or related group of persons (other than the

AUTOMATIC OPTION GRANT PROGRAM

4.1 TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS

(a) AMOUNT AND DATE OF GRANT. During the term of this Plan, automatic
option grants (the "Automatic Option Grant") shall be made to each eligible
non-employee member of the Board ("Optionee") as follows:

(i) Each year on the Annual Automatic Grant Date an option to
acquire 6,000 shares of Common Stock ("Option Shares") shall be granted to each
eligible non-employee member of the Board for so long as there are shares of
Common Stock available under Section 1.5 hereof. The "Annual Automatic Grant
Date" shall be as of the first business day of the month in which the
Corporation's Annual Stockholders Meeting is held. Notwithstanding the
foregoing, (1) any non-Employee Member of the Board whose term ended as of such
Automatic Grant Date shall not be eligible to receive any automatic option
grants on that Annual Automatic Grant Date and (2) any non-Employee Member of
the Board who has received an Automatic Grant pursuant to Section 4.1(a)(ii) on
the same date as the Annual Automatic Grant Date or within 30 days prior
thereto, shall not be eligible to receive an Automatic Option Grant on that
Annual Automatic Grant Date.

(ii) On the Initial Automatic Grant Date, every new member of the
Board who is an eligible non-Employee and has not previously been a member of
the Board shall be granted an option to acquire 12,000 shares of Common Stock
("Option Shares") as long as there are shares of Common Stock available under
Section 1.5 hereof. The "Initial Automatic Grant Date" shall be as of the date
that the Optionee was first appointed or elected to the Board.

(b) EXERCISE PRICE. The exercise price per share of Common Stock
subject to each automatic option grant made under this Article IV shall be equal
to 100% of the fair market value per share of the Common Stock on the applicable
Automatic Grant Date, as determined in accordance with the valuation provisions
of Section 2.1(d) hereof.

(c) METHOD OF EXERCISE. In order to exercise an option with respect
to any Option Shares for which an Automatic Option Grant is exercisable at the
time, Optionee (or in the case of an exercise after Optionee's death, Optionee's
executor, administrator, heir or legatee, as the case may be) must take the
following action:

13
(i) execute and deliver to the Secretary of the Company a
written notice of exercise;

(ii) pay the aggregate Option Price in one of the alternate forms
as set forth in Section 4.1(d) below; and

(iii) furnish appropriate documentation that the person or
persons exercising the option (if other than the Optionee) has the right to
exercise such option. As soon after the Exercise Date (as defined in Section
4.1(e) hereof), as practical, the Company shall mail or deliver to or on behalf
of the Optionee (or any other person or persons exercising this option in
accordance herewith) a certificate or certificates representing the shares for
which the option has been exercised in accordance with the provisions of this
Plan. In no event may any option be exercised for any fractional shares.

(d) PAYMENT PRICE. The exercise price shall be payable in one of the
alternative forms specified below:

(i) full payment in cash or check made payable to the
Corporation's order; or

(ii) full payment in shares of Common Stock held for the
requisite period necessary to avoid a charge to the Corporation's earnings for
financial reporting purposes and valued at fair market value on the Exercise
Date (as such term is defined below); or

(iii) full payment in a combination of shares of Common Stock
held for the requisite period necessary to avoid a charge to the Corporation's
earnings for financial reporting purposes and valued at fair market value on the
Exercise Date and cash or check drawn to the Corporation's order; or

(iv) full payment through a sale and remittance procedure
pursuant to which the non-employee Board member (A) shall provide irrevocable
written instructions to a designated brokerage firm to effect the immediate sale
of the purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares and shall (B) concurrently
provide written directives to the Corporation to deliver the certificates for
the purchased shares directly to such brokerage firm in order to complete the
sales transaction.

For purposes of this Section 4.1.(d), the Exercise Date shall be the
date on which written notice of the option exercise is delivered to the
Corporation. Except to the extent the sale and remittance procedure is utilized
in connection with the exercise of the option, payment of the exercise price for
the purchased shares must accompany such notice.

(e) EXERCISE DATE. For purposes of this Article IV, the Exercise Date
shall be the date on which written notice of the option exercise is delivered to
the Corporation, and the fair market value per share of Common Stock on any
relevant date under this Article IV shall be determined in accordance with the
provisions of Section 2.1(d) hereof. Except to the extent the sale and

14
remittance procedure specified above is utilized for the exercise of the potion,
payment of the option price for the purchased shares must accompany the exercise
notice.

(f) TERM OF OPTION. Each Automatic Option Grant under this Article IV
shall have a maximum term of ten (10) years measured from the Automatic Grant
Date. Should Optionee's service as a Board member cease for any reason while an
option remains outstanding and unexercised, then the option term shall
immediately terminate and the option shall cease to be outstanding prior to the
Expiration Date in accordance with the following provisions:

(i) The option shall immediately terminate and cease to be
outstanding for any shares of Common Stock for which the option was not
otherwise exercisable at the time of Optionee's cessation of Board service.

(ii) Should Optionee cease, for any reason other than death, to
serve as a member of the Board, then Optionee shall have a six-month period
measured from the date of such cessation of Board service in which to exercise
the options which vested prior to the time of such cessation of Board service.
In no event, however, may any option be exercised after the Expiration Date of
such option.

(iii) With respect to options granted on or after April 1, 2002,
all such unvested options shall immediately vest upon the Optionee's death if
said Optionee's death occurs during Optionee's Board service. Should Optionee
die while serving as a Board member or within six months after cessation of
Board service, then the personal representative of the Optionee's estate (or the
person or persons to whom the option is transferred pursuant to the Optionee's
will or in accordance with the laws of descent and distribution) shall have the
right to exercise any option for any or all of the shares of Common Stock for
which the option is, in accordance with the provisions of this Plan, exercisable
at the time of the Optionee's cessation of Board service, less any shares
subsequently purchased by the Optionee pursuant to the option prior to death.
Such right shall cease to be exercisable and the option shall accordingly
terminate with respect to all Common Stock available under such option by the
earlier of (A) the expiration of the twelve-month period measured from the date
of Optionee's death or (B) the Expiration Date.

(g) VESTING. Each Automatic Option Grant made pursuant to Section
4.1(a)(i) shall become exercisable and vest in a series of twelve (12) equal and
successive monthly installments, with the first such installment to become
exercisable one month after the Annual Automatic Grant Date. Each Automatic
Option Grant made pursuant to Section 4.1(a)(ii) shall become exercisable and
vest in a series of 36 equal and successive monthly installments, with the first
such installment to become exercisable one month after the Initial Automatic
Grant Date. Each installment of an option shall only vest and become exercisable
if the Optionee has not ceased serving as a Board member as of such installment
date.

(h) LIMITED TRANSFERABILITY. Except as otherwise determined by the
Administrator, each Automatic Option Grant shall be exercisable only by Optionee
during Optionee's lifetime and shall be neither transferable nor assignable,
other than by will or by the laws of descent and distribution following
Optionee's death.

15
4.2 CORPORATE TRANSACTION

In the event of stockholder approval of a Corporate Transaction (as
that term is defined in Section 2.3(a)), then all options granted pursuant to
this Article IV (to the extent outstanding at such time, but not otherwise fully
exercisable and vested) shall automatically accelerate and immediately vest so
that the option shall, immediately prior to the specified effective date for the
Corporate Transaction, become fully exercisable for all of the Option Shares at
the time subject to the option and may thereafter be exercised for any or all
such Option Shares. Upon the consummation of the Corporate Transaction, the
option shall, to the extent not previously exercised, terminate and cease to be
outstanding.

4.3 CHANGE IN CONTROL

All options granted pursuant to an Automatic Option Agreement under
this Article IV (to the extent outstanding, but not otherwise fully exercisable
and vested) shall automatically accelerate in connection with a Change in
Control (as that term is defined in Section 2.4(a)), so that such option shall,
immediately prior to the effective date of such Change in Control, become fully
exercisable for all of the Option Shares at the time subject to that option and
may be exercised for any or all of such Option Shares. The option shall remain
so exercisable until such option has terminated in accordance with Section
4.1(d) hereof.

4.4 MISCELLANEOUS PROVISIONS

(a) CORPORATION RIGHTS. The Automatic Option Grants shall in no way
affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

(b) PRIVILEGE OF STOCK OWNERSHIP. An Optionee shall not have any of
the rights of a stockholder with respect to Option Shares until such individual
shall have exercised the option and paid the option price for the Option Shares.

16
ARTICLE V
MISCELLANEOUS

5.1 AMENDMENT OF THE PLAN AND AWARDS

(a) BOARD AUTHORITY. The Board has complete and exclusive power and
authority to amend or modify the Plan (or any component thereof) in any or all
respects whatsoever. However, no such amendment or modification shall, without
the consent of the Corporation's stockholders, disqualify any option previously
granted under the Plan for treatment as an Incentive Option, or adversely affect
rights and obligations with respect to options at the time outstanding under the
Plan, unless the Optionee or Participant consents to such amendment. In
addition, the Board may not, without the approval of the Corporation's
stockholders, amend the Plan to (i) materially increase the maximum number of
shares issuable under the Plan, except for permissible adjustments under Section
1.5(d) or extend the term of the Plan, (ii) materially modify the eligibility
requirements for plan participation or (iii) materially increase the benefits
accruing to plan participants.

(b) OPTIONS ISSUED PRIOR TO STOCKHOLDER APPROVAL. Options to purchase
shares of Common Stock may be granted under the Discretionary Option Grant
Program and the Automatic Option Grant Program prior to any required stockholder
approvals, provided, any shares actually issued under the Plan are held in
escrow until stockholder approval is obtained. If such stockholder approval is
not obtained within twelve (12) months of the meeting of the Board approving the
Plan or any amendments, then (i) any unexercised options shall terminate and
cease to be exercisable and (ii) the Corporation shall promptly refund the
purchase price paid for any excess shares actually issued under the Plan and
held in escrow, together with interest (at the applicable Short Term Federal
Rate) for the period the shares were held in escrow.

(c) RULE 16B-3 PLAN. With respect to persons subject to Section 16 of
the 1934 Act, the Plan is intended to comply with all applicable conditions of
Rule 16b-3 (and all subsequent revisions thereof) promulgated under the 1934
Act. To the extent any revision of the Plan or action by any Plan Administrator
fails to so comply, it shall be deemed null and void, to the extent permitted by
law and deemed advisable by such Plan Administrator. In addition, the Board may
amend the Plan from time to time as it deems necessary in order to meet the
requirements of any amendments to Rule 16b-3 without the consent of the
shareholders of the Company.

5.2 TAX WITHHOLDING

(a) GENERAL. The Corporation's obligation to deliver shares of Common
Stock upon the exercise of stock options for such shares or the vesting of such
shares under the Plan shall be subject to the satisfaction of all applicable
Federal, State and local income tax and employment tax withholding requirements.

(b) SHARES TO PAY FOR WITHHOLDING. A Plan Administrator may, in its
discretion and in accordance with the provisions of this Section 5.2(b) and such
supplemental rules as the Plan Administrator may from time to time adopt

17
(including the applicable safe-harbor provisions of SEC Rule 16b-3), provide any
or all holders of non-statutory options or unvested shares under the Plan with
the right to use shares of the Corporation's Common Stock in satisfaction of all
or part of the Federal, State and local income tax and employment tax
liabilities incurred by such holders in connection with the exercise of their
options or the vesting of their shares (the "Taxes"). Such right may be provided
to any such holder in either or both of the following formats:

(i) STOCK WITHHOLDING. The holder of the non-statutory option or
unvested shares may be provided with the election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such non-statutory option or the vesting of such shares, a portion of those
shares with an aggregate fair market value equal to the percentage of the
applicable Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

(ii) STOCK DELIVERY. The Plan Administrator may, in its
discretion, provide the holder of the non-statutory option or the unvested
shares with the election to deliver to the Corporation, at the time the
non-statutory option is exercised or the shares vest, one or more shares of
Common Stock previously acquired by such individual (other than pursuant to the
transaction triggering the Taxes) with an aggregate fair market value equal to
the percentage of the taxes incurred in connection with such option exercise or
share vesting (not to exceed one hundred percent (100%)) designated by the
holder.

Option Grant Program shall be incorporated into this Plan and treated as an
outstanding option under this Plan, but each such option shall continue to be
governed solely by the terms and conditions of the instrument evidencing such
grant, and nothing in this Plan shall be deemed to affect or otherwise modify
the rights or obligations of the holders of such options with respect to their
acquisition of shares of Common Stock thereunder.

(c) DISCRETION. The option and vesting acceleration provisions of
Article II relating to Corporate Transactions and Changes in Control may, in the
Plan Administrator's discretion, be extended to one or more stock options which
are outstanding under the 1989 Plan on the Effective Date of the Discretionary
Option Grant Program but which do not otherwise provide for such acceleration.

18
(d) TERMINATION OF PLAN. The Plan shall terminate upon the earlier of
(i) January 19, 2013(2) or (ii) the date on which all shares available for
issuance under the Plan shall have been issued pursuant to the exercise of
options granted under the Plan. If the date of termination is determined under

stock of the same class is then listed.

any action taken by the Plan Administrator hereunder, nor any provision of the
Plan shall be construed so as to grant any individual the right to remain in the
employ or service of the Corporation (or any parent or subsidiary corporation)
for any period of specific duration, and the Corporation (or any parent or
subsidiary corporation retaining the services of such individual) may terminate
such individual's employment or service at any time and for any reason, with or
