					Benedict C.K. Choy

Sunnyvale, California

                              SUPERTEX, INC.
                             PROXY STATEMENT

              SOLICITATION OF PROXY, REVOCABILITY AND VOTING

General

The enclosed Proxy is solicited on behalf of the Board of Directors of
Supertex, Inc., a California corporation (the "Company"), for use at the
2000 Annual Meeting of Shareholders to be held on August 18, 2000 at
10:00 a.m., local time, or at any adjournment thereof, for the purposes
set forth herein and in the accompanying Notice of Annual Meeting of
Shareholders.

Only shareholders of record at the close of business on June 26, 2000
(the "Record Date") are entitled to notice of and to vote at the meeting.
At the Record Date 12,301,701 shares of the Company's Common Stock, no
par value, were issued and outstanding.

The Annual Meeting will be held at the principal offices of the Company
located at 1235 Bordeaux Drive, Sunnyvale, California 94089.  The Company's
telephone number at that address is (408) 744-0100.

These proxy solicitation materials will be mailed on or about July 12, 2000
to all shareholders entitled to vote at the meeting.

Revocability of Proxies

Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use (i) by delivering to the Secretary of
the Company a written notice of revocation or a duly executed proxy bearing
a later date or (ii) by attending the meeting and voting in person.

Voting and Solicitation

Every shareholder voting at the election of directors may cumulate such
shareholder's votes and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of votes to
which the shareholder's shares are entitled, or distribute the
shareholder's votes on the same principle among as many candidates as the
shareholder thinks fit, provided that votes cannot be cast for a greater
number of candidates than the number of directors to be elected.  However,
no shareholder shall be entitled to cumulate votes unless the candidate's
name has been placed in nomination prior to the voting and the shareholder,
or any other shareholder, has given notice at the meeting prior to the
voting of the intention to cumulate the shareholder's votes.  On all other
matters, each share has one vote.  An automated system administered by the
Company's transfer agent, Registrar and Transfer Company, tabulates the
votes.

Quorum; Abstentions; Broker Non-Votes

The required quorum for the transaction of business at the Annual Meeting
is a majority of the shares of Common Stock issued and outstanding on the
Record Date.  Shares that are voted "FOR", "AGAINST" or "WITHHELD FROM"
a matter are treated as being present at the meeting for purposes of
establishing a quorum and are also treated as shares "represented and
voting" at the Annual Meeting (the "Votes Cast") with respect to such
matter.

While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions, the Company believes that
abstentions should be counted for purposes of determining the presence
or absence of a quorum for the transaction of business, but should not be
counted as Votes Cast with respect to a proposal, since the shareholder
has expressly declined to vote on such proposal.  Similarly, broker
non-votes will be counted for purposes of determining the presence or
absence of a quorum for the transaction of business, but will not



be counted for purposes of determining the number of Votes Cast with respect
to the proposal on which the broker has expressly not voted.

Accordingly, abstentions and broker non-votes will not affect the outcome of
the voting on a proposal that requires a majority of the Votes Cast (such
as the approval of the adoption of a plan).  However, with respect to a
proposal that requires a majority of the outstanding shares, (such as an
amendment to the articles of incorporation), an abstention or broker
non-vote has the same effect as a vote against the proposal.

The Company will bear the entire cost of preparing, assembling, printing,
and mailing this Proxy Statement.  In addition, the Company may reimburse
brokerage firms and other persons representing beneficial owners of shares
for their expenses in forwarding solicitation materials to such beneficial
owners.  Proxies may also be solicited personally or by telephone or by
fax by certain of the Company's directors, officers, and regular employees
- - such persons will not receive additional compensation for such
solicitation.

Deadline for Receipt of Shareholder Proposals

Proposals of security holders of the Company which are intended to be
presented by such shareholders at the Company's Annual Meeting for fiscal
2001 must be received by the Company no later than February 24, 2001 in
order that they may be included in the proxy statement and form of proxy
relating to that meeting.

                   PROPOSAL 1:  ELECTION OF DIRECTORS

Nominees

The board of directors recently amended the bylaws to increase the
authorized number of directors from five (5) to six (6).  Therefore, a
board of six directors is to be elected at the meeting.  Mr. Yunni Pao,
a director since 1976, has declined re-election to the Board for personal
reasons; therefore, there will be two new members on the board.  The board
has nominated Mr. W. Mark Loveless and Mr. Elliott Schlam for election as
new members of the board for the ensuing year in addition to nominating
the remaining four current members. Unless otherwise instructed, the
proxy holders will vote the proxies received by them for the Company's
six nominees named below.  The six nominees receiving the highest number
of affirmative votes of the shares entitled to be voted will be elected as
directors of the Company.  In the event that any nominee of the Company
declines or is unable to serve as a director at the time of the Annual
Meeting, the proxies will be voted for any nominee who shall be designated
by the present Board of Directors to fill the vacancy.  It is not expected
that any nominee will decline or will be unable to serve as a director.
In the event that additional persons are nominated for election as
directors and/or votes are cumulated, the proxy holders intend to vote
all proxies received by them in such a manner as will ensure the election
of as many of the nominees listed below as possible, and, in such event,
the specific nominees to be voted for will be determined by the proxy
holders.  The term of office of each person elected as a director will
continue until the next Annual Meeting of Shareholders or until such
person's successor has been elected and qualified.  The names of the
nominees and certain information about them are set forth below.

purposes of determining the presence or absence of a quorum, but have no
other legal effect under California law.

the above-named persons to the board of directors of the Company.

Board Meetings and Committees

The Board of Directors of the Company held a total of two meetings during
the fiscal year ended April 1, 2000.  All directors attended every meeting
during such fiscal year.



The Board of Directors has an Audit Committee, a Compensation Committee,
and an Executive Stock Option Committee.  The Board has no special
nominating committee or any committee performing similar functions of
such committee.  Any member of the Board can make nominations.

Audit Committee

The Audit Committee consists of two outside directors, Yunni Pao and
Frank Pao, and one inside director, Benedict Choy, who is not involved
in the Company's day-to-day financial matters.  The principal functions
of the Audit Committee are (1) to monitor corporate financial reporting
and the internal and external audits of the Corporation (2) to review and
evaluate the Company's internal control structure, and (3) to nominate
independent public accountants and approve the services performed by such
auditors.  The Audit Committee held one meeting in fiscal year 2000 and
such meeting was attended by all Audit Committee members.

Compensation Committee

The Compensation Committee consists of Yunni Pao, Henry C. Pao, and
Benedict Choy.  The Compensation Committee is responsible for making
recommendations to the Board of Directors with respect to all cash-based
compensation of the executive officers of the Company and all stock
compensation of employees and consultants other than stock options to
members of the board of directors and executive officers.  It also serves
as an administrator of the Company's 1991 Stock Option Plan and would
administer the Employee Stock Purchase Plan being proposed for approval
at the meeting.  The Compensation Committee held one meeting in fiscal
year 2000, and such meeting was attended by all Compensation Committee
members.

Compensation Committee Interlocks and Insider Participation

Benedict Choy and Henry C. Pao serve on the Compensation Committee and
are also officers of the Company.  Yunni Pao, the father of Henry Pao and
Frank Pao, is a member of the Company's Compensation Committee.

Executive Stock Option Committee

The Executive Stock Option Committee, consisting of Yunni Pao and Frank Pao,
serves as an administrative arm of the Board of Directors to authorize the
grant of stock options under the Company's 1991 Stock Option Plan to
executive officers and members of the board of directors of the Company
eligible to receive options under such Plan.

         Report of the Compensation Committee and Executive Stock
               Option Committee of the Board of Directors

The Compensation Committee of the Board of Directors is generally
responsible for reviewing compensation and benefits of executive officers
of the Company; except for the stock options to executive officers and
directors of the Company, for which the Executive Stock Option Committee
is responsible.

The Company applies a consistent philosophy of compensation for all
employees, including its executive officers.  This philosophy is based on
the premise that the achievements of the Company result from the
coordinated efforts of all individuals working toward common objectives.
The Company strives to achieve those objectives through teamwork that is
focused on meeting the defined expectations of customers and shareholders.

Compensation Philosophy.  The goals of these committees are to align
executive compensation with business objectives and performance, and to
enable the Company to attract, retain and reward executive officers who
contribute to the long-term success of the Company.  The Company's
compensation program for the chief executive officer and other executive
officers is based on the same four principles applicable to compensation
decisions for all employees of the Company:



*     The Company pays competitively.  The Company is committed to
      providing a compensation program that helps attract and retain the
      best people in the industry.  To ensure that pay is competitive, the
      Company reviews the compensation practices of other companies of
      similar size and sales volume within the semiconductor industry,
      most of which are included in the Nasdaq Electronic Component Index.

*     The Company pays for relative sustained performance.  Officers are
      rewarded based upon corporate performance, product line performance
      and individual performance.  Corporate performance and product line
      performance are evaluated by reviewing the extent to which strategic
      and business plan goals are met, including such factors as operating
      profit, performance relative to competitors and timely new product
      introductions.  Individual performance is evaluated by measuring
      organization progress against set objectives.

*     The Company strives for fairness in the administration of
      compensation.  The Company strives to achieve a balance with respect
      to compensation paid to the executives within the Company and in
      comparable companies.  The Company also believes that the
      contributions of each member of the executive staff are vital to the
      success of the Company.  As such, the Compensation Committee's
      current policy is that the CEO's base compensation does not have any
      bearing on the base compensation of the other officers.  Similarly,
      any employee may receive a base compensation higher than his/her
      supervisor due to the particular higher technical skills required in
      the subordinate position.

*     The Company believes that employees should understand the performance
      evaluation and compensation administration process.  At the beginning
      of each focal review period in July, annual objectives for the Company
      are set for each officer.  The CEO gives ongoing feedback on
      performance to each officer.  Within 90 days after the end of the
      fiscal year, the committees evaluate the accomplishments of the key
      objectives, which affects decisions on merit increases and stock
      option grants.

Compensation Components.  The Company's compensation program, which consists
of cash- and equity-based compensation, allows the Company to attract and
retain highly skilled officers, provide useful products and services to
customers, enhance shareholder value, motivate technological innovation and
adequately reward its executive officers and other employees.  These
components are:

Cash-Based Compensation:

Salary.  The Compensation Committee sets base salary for the chief executive
officer and all other officers by reviewing the compensation levels for
competitive positions in the market.  Based on comparative data, the chief
executive and all other officers were compensated within the low-to-middle
salary range levels during fiscal 2000.  The chief executive and all other
executive officers of the Company largely met their individual goals and
the Company's overall performance set for them in fiscal 2000.

Profit-Sharing Bonus.  The Company has a semiannual profit-sharing plan
under which it distributes to all employees, including the chief executive
officer and all other officers, ten percent of its operating profits before
taxes and other adjustments.  The Company believes that all employees share
the responsibility of achieving profits.  Accordingly, it awards a bonus to
all employees based on a formula which includes employment grade level,
seniority with the Company, and employee performance including attendance.
As of June 26, 2000, the Company has made twenty-four consecutive semiannual
profit-sharing distributions.



Equity-Based Compensation:

Stock Option Grants.  Stock options provide additional incentives to the
chief executive officer and all other officers, directors, and certain
management and technical employees to work to maximize stockholder value.
The options vest over a defined period to encourage such employees to
continue in the employ of the Company.  In line with its compensation
philosophy, the Company grants stock options commensurate with the
employee's potential contribution to the Company, measured by his
qualifications and previous work performance.  Stock options were granted
to various officers, management or technical employees in fiscal year 2000
for performance and promotions of existing employees, and as a part of the
employment compensation package for new employees.

                    -Respectfully submitted by the members of the
                     Compensation Committee

                                         Yunni Pao       Henry C. Pao
                                         Benedict C. K. Choy

Compensation of Directors

Cash Compensation.  The Company currently pays cash compensation to its
outside Directors for serving on the Board or committees of the Board in
an amount of $1,000 for each Board meeting attended in person not via
telephone.  The Company also reimburses all outside Directors for travel
and other necessary out-of-pocket expenses incurred in the performance of
their services as directors.

Stock Option Grant.   The new nominees, Mr. Loveless and Mr. Schlam, will
each be granted on September 1, 2000 stock options to purchase 10,000
shares of the Company's Common Stock vested over a five-year period, if
they are elected to the Board of Directors.

Certain Transactions:  Lease with Company Director

The Sunnyvale, California four-inch wafer manufacturing facility of the
Company, which is being phased out due to the Company's acquisition of a
six-inch wafer manufacturing facility in San Jose, California, is leased
from Fortuna Realty Co., a corporation owned by Supertex Director, Yunni
Pao.  The five-year operating lease agreement with Fortuna Realty expires
in February 2001.  The total rental expenses paid to the company director
were $388,000, $375,000, and $362,000 in fiscal 2000, 1999, and 1998,
respectively.  The Company believes that the lease with Fortuna Realty Co.
is at prevailing market rates.

the ability to invest in the Company's common stock at an attractive price
and to have an additional incentive to contribute to the prosperity of the
Company.

DESCRIPTION OF THE PLAN

The Plan, if approved by the shareholders, will allow eligible employees
to authorize payroll deductions at a rate of not less than three percent
(3%) nor more than twenty percent (20%) of the eligible employee's
compensation including salaries, wages, bonuses, incentive compensation,
commissions, overtime pay and shift premiums to be applied toward the
purchase of the Company's common stock. The maximum aggregate number of
common stock available for purchase under the plan is 500,000 shares plus
an annual increase on the first day of the Company's fiscal year of the
lesser of 100,000 shares or three percent (3%) of the outstanding shares
on that date or a lesser amount determined by the Board.  The number of
shares reserved under the Plan would be proportionately adjusted in the
event of any stock split, reverse stock split, stock dividend, or other
like event.  A committee appointed by the Board of Directors, presently
the Compensation Committee, will administer the Plan.

Eligible employees are those employees of the Company or any designated
subsidiary who work more than 20 hours a week and more than five months a
year.  However, no employee shall be permitted to purchase any shares
under the Plan if such employee, immediately after such purchase, owns
shares possessing five percent or more of the total combined voting power
or value of all classes of stock of the Company.  As of June 28, 2000,
approximately 385 employees were eligible to participate in the Plan,
including seven executive officers.

No employee may purchase more than 500 shares or of stock during any
single offering. In addition, the fair market value of all shares
purchased by an employee under the Plan during any calendar year may not
exceed $10,000.

Separate offering periods commence on May 1 and November 1 of each year,
except for the initial year.   The length of the offering period is six
(6) months unless otherwise determined by the board of directors or the
administering committee.  An offering period will continue to apply to a
participant until the earliest of the end of the offering period, or the
end of his or her participation, or re-enrollment in a subsequent
offering period.  If the offering period is longer than six (6) months,
participants are automatically re-enrolled in a subsequent offering period
when the fair market value of the common stock on the last trading day
before the commencement of the offering period in which the participants
is enrolled is higher than on the last trading day before the commencement
of any subsequent offering period.  An employee must authorize a payroll
deduction before the start of an offering period in order to participate in
the Plan during that offering period.

Stock is purchased under the Plan at the end of each six-month period
commencing on May 1 and November 1 of each year, except for the initial
year. On the last trading day of the purchase period, the employee will be
deemed to have exercised the option to purchase as many shares as the
employee's payroll deduction will allow, at the option price. The option
price is 85% of the lower of (i) the fair market value of the stock on the
last trading day prior to the start of the offering period, or (ii) the
fair market value of the stock on the last trading day of the purchase
period. The number of shares subject to an option, and the option price,
would be proportionately adjusted in the event of any stock split, reverse
stock split, stock dividend, or other like event.

An employee may withdraw from an offering at any time. Upon withdrawal,
the amount in the employee's account will be refunded without interest.
An employee who has withdrawn from an offering may not again participate
in the Plan until the next offering period commences.

The Board of Directors may at any time amend, suspend or terminate the
Plan at any time and without notice, provided that no employee's existing
rights under any offering already commenced may be adversely affected



thereby. No amendment may be made to the Plan without prior approval of
the shareholders of the Company if such amendment would increase the
number of shares reserved thereunder, materially modify the eligibility
requirements, or materially increase the benefits that may accrue to
participants.

FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE PLAN

The federal income tax consequences of an employee's purchases under the
Plan will vary. The following discussion is only a summary of the general
federal income tax rules applicable to the Plan. It does not purport to
be complete, and it does not discuss the tax consequences of the
participant's death or the income tax laws of any municipality, state or
foreign country in which a participant may reside.

The Plan is intended to be an "employee stock purchase plan" within the
meaning of Section 423 of the Internal Revenue Code.  Under such a plan,
no taxable income is recognized by the participant either when the
purchase right is granted at the beginning of the offering period or when
the shares are purchased at the end of each accumulation period.
Participants will recognize income in the year in which they make a
disposition of the purchased shares, whether by sale, exchange or gift.
Federal income tax liability on disposition depends on whether the
disposition is a qualifying or disqualifying disposition of the purchased
shares.  A qualifying disposition will occur if the sale or other
disposition of those shares is made after the participant has held the
shares for (a) more than two years after the start date of the applicable
offering period and (b) more than one year after the actual purchase date.
A disqualifying disposition is any sale or other disposition which is made
before both of these two holding periods are satisfied.

If the disposition is a qualifying disposition, the participant will
recognize ordinary income in the year of the qualifying disposition equal
to the lesser of (a) the amount by which the fair market value of the
shares on the date of the qualifying disposition exceeds the purchase
price paid for those shares or (b) 15% of the fair market value of the
shares on the start date of the offering period during which those shares
were purchased.  The Company is not entitled to an income tax deduction
with respect to such disposition.  Any additional gain recognized upon the
qualifying disposition will be long term capital gain.  If the fair market
value of the shares on the date of the qualifying disposition is less than
the purchase price, there will be no ordinary income, and any loss
recognized will generally be a long-term capital loss.

If the disposition is a disqualifying disposition, the participant will
recognize ordinary income equal to the excess of (a) the fair market value
of the shares on the purchase date over (b) the purchase price paid for
the shares.  The Company is entitled to an income tax deduction equal in
amount to such excess for the taxable year in which such disposition
occurs. Any additional gain recognized upon the disqualifying disposition
will be capital gain.  The capital gain will be long-term if the
participant held the shares more than one year.

The Board of Directors recommend a vote FOR the approval of the adoption
of the 2000 Employee Stock Purchase Plan. The vote required is the
affirmative vote of a majority of the shares of common stock present or
represented by proxy and entitled to vote at the meeting.

Accumulation Period immediately following the date that such form has been

7. Change in Employment Status.

	7.1  Termination of Employment.  Termination of employment as an
Eligible Employee for any reason, including death, shall be treated as an
automatic withdrawal from the Plan under Section 6.1.  Notwithstanding the
foregoing in this Section 7, a transfer from one Participating Company to
another shall not be treated as a termination of employment.

	7.2  Leave of Absence.  For purposes of the Plan, employment shall
not be deemed to terminate when the Participant goes on a military leave,
a sick leave or another bona fide leave of absence, if the leave was
approved by the Company in writing.  Employment, however, shall be deemed
to terminate ninety (90) days after the Participant goes on a leave, unless
a contract or statute guarantees his or her right to return to work.
Employment shall be deemed to terminate in any event when the approved leave
ends, unless the Participant immediately returns to work.

	7.3  Death.  In the event of the Participant's death, the amount
credited to his or her Plan Account shall be paid to a beneficiary
designated by him or her for this purpose on the prescribed form or, if
none, to the Participant's estate.  Such form shall be valid only if it was

8. Plan Accounts and Purchase of Shares.

	8.1  Plan Accounts.  The Company shall maintain a Plan Account on
its books in the name of each Participant.  Whenever an amount is deducted
from the Participant's Compensation under the Plan, such amount shall be
credited to the Participant's Plan Account.  Amounts credited to Plan
Accounts shall not be trust funds and may be commingled with the Company's
general assets and applied to general corporate purposes.  No interest shall
be credited to Plan Accounts.

	8.2  Purchase Price.  The Purchase Price for each share of Stock
purchased at the close of an Accumulation Period shall be the lower of:

        (i)  85% of the Fair Market Value of such share on the last
trading day in such Accumulation Period; or

        (ii) 85% of the Fair Market Value of such share on the last
trading day before the commencement of the applicable Offering Period
(as determined under Section 4.5).

	8.3  Number of Shares Purchased.  As of the last day of each
Accumulation Period, each Participant shall be deemed to have elected to
purchase the number of shares of Stock calculated in accordance with this
Section 8.3, unless the Participant has previously elected to withdraw
from the Plan in accordance with Section 6.1.  The amount then in the
Participant's Plan Account shall be divided by the Purchase Price, and
the number of shares that results shall be purchased from the Company with
the funds in the Participant's Plan Account.  The foregoing notwithstanding,
no Participant shall purchase more than five hundred (500) shares of Stock
with respect to any Accumulation Period nor more than the amounts of Stock
set forth in Sections 9.2 and 14.1. The Committee may determine with
respect to all Participants that any fractional share, as calculated under
this Subsection 8.3, shall be (i) rounded down to the next lower whole
share or (ii) credited as a fractional share.

	8.4  Available Shares Insufficient.  In the event that the
aggregate number of shares that all Participants elect to purchase during
an Accumulation Period exceeds the maximum number of shares remaining
available for issuance under Section 14.1, then the number of shares to
which each Participant is entitled shall be determined by multiplying the
number of shares available for issuance by a fraction, the numerator of
which is the number of shares that such Participant has elected to
purchase and the denominator of which is the number of shares that all
Participants have elected to purchase.

        8.5  Issuance of Stock.  Certificates representing the shares of
Stock purchased by a Participant under the Plan shall be issued to him or
her as soon as reasonably practicable after the close of the applicable
Accumulation



Period, except that the Committee may determine that such
shares shall be held for each Participant's benefit by a broker designated
by the Committee (unless the Participant has elected that certificates be
issued to him or her).  Shares may be registered in the name of the
Participant or jointly in the name of the Participant and his or her spouse
as joint tenants with right of survivorship or as community property.

	8.6  Unused Cash Balances.  An amount remaining in the Participant's
Plan Account that represents the Purchase Price for any fractional share
shall be carried over in the Participant's Plan Account to the next
Accumulation Period.  Any amount remaining in the Participant's Plan
Account that represents the Purchase Price for whole shares that could not
be purchased by reason of Section 8.3 above, Section 9.2 or Section 14.1
shall be refunded to the Participant in cash, without interest.

	8.7  Stockholder Approval.  Any other provision of the Plan
notwithstanding, no shares of Stock shall be purchased under the Plan unless
and until the Company's stockholders have approved the adoption of the Plan.

9. Limitations on Stock Ownership.

	9.1  Five Percent Limit.  Any other provision of the Plan
notwithstanding, no Participant shall be granted a right to purchase Stock
under the Plan if such Participant, immediately after his or her election
to purchase such Stock, would own stock possessing more than 5% of the total
combined voting power or value of all classes of stock of the Company or any
parent or Subsidiary of the Company.  For purposes of this Section 9.1, the
following rules shall apply:

        (i)   Ownership of stock shall be determined after applying the
attribution rules of section 424(d) of the Code;

        (ii)  Each Participant shall be deemed to own any stock that he
or she has a right or option to purchase under this or any other plan; and

        (iii) Each Participant shall be deemed to have the right to
purchase five hundred (500) shares of Stock under this Plan with respect to
each Accumulation Period.

	9.2  Dollar Limit.  Any other provision of the Plan notwithstanding,
no Participant shall purchase Stock with a Fair Market Value in excess of
$10,000 per calendar year (under this Plan and all other employee stock
purchase plans of the Company or any parent or Subsidiary of the Company).

	For purposes of this Section 9.2, the Fair Market Value of Stock
shall be determined in each case as of the beginning of the Offering Period
in which such Stock is purchased.  Employee stock purchase plans not
described in section 423 of the Code shall be disregarded.  If a Participant
is precluded by this Section 9.2 from purchasing additional Stock under the
Plan, then his or her employee contributions shall automatically be
discontinued and shall resume at the beginning of the earliest Accumulation
Period ending in the next calendar year (if he or she then is an Eligible
Employee).

10. Rights Not Transferable.  The rights of any Participant under the Plan,
or any Participant's interest in any Stock or moneys to which he or she may
be entitled under the Plan, shall not be transferable by voluntary or
involuntary assignment or by operation of law, or in any other manner other
than by beneficiary designation or the laws of descent and distribution.
If a Participant in any manner attempts to transfer, assign or otherwise
encumber his or her rights or interest under the Plan, other than by
beneficiary designation or the laws of descent and distribution, then such
act shall be treated as an election by the Participant to withdraw from the
Plan under Section 6.1.

11. No Rights as an Employee.  Nothing in the Plan or in any right granted
under the Plan shall confer upon the Participant any right to continue in
the employ of a Participating Company for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the
Participating Companies or of the Participant, which rights are hereby
expressly reserved by each, to terminate his or her employment at any time
and for any reason, with or without cause.

12. No Rights as a Stockholder.  A Participant shall have no rights as a
stockholder with respect to any shares of Stock that he or she may have a
right to purchase under the Plan until such shares have been purchased on
the last day of the applicable Offering Period.



13. Securities Law Requirements.  Shares of Stock shall not be issued under
the Plan unless the issuance and delivery of such shares comply with (or
are exempt from) all applicable requirements of law, including (without
limitation) the Securities Act of 1933, as amended, the rules and
regulations promulgated thereunder, state securities laws and regulations,
and the regulations of any stock exchange or other securities market on
which the Company's securities may then be traded.

14. Stock Offered under the Plan.

	14.1  Authorized Shares.  The maximum aggregate number of shares of
Stock available for purchase under the Plan is five hundred thousand
(500,000), plus an annual increase to be added on the first day of the
Company's fiscal year beginning in 2001 equal to the lesser of (i) one
hundred thousand (100,000) shares, (ii) three percent (3%) of the
outstanding shares on such date or (iii) a lesser amount determined by the
Board.  The aggregate number of Shares available for purchase under the
Plan shall at all times be subject to adjustment pursuant to Section 14.

	14.2  Antidilution Adjustments.  The aggregate number of shares of
Stock offered under the Plan, the five hundred (500) share limitation
described in Section 8.3 and the price of shares that any Participant has
elected to purchase shall be adjusted proportionately by the Committee for
any increase or decrease in the number of outstanding shares of Stock
resulting from a subdivision or consolidation of shares or the payment of
a stock dividend, any other increase or decrease in such shares effected
without receipt or payment of consideration by the Company, the
distribution of the shares of a Subsidiary to the Company's stockholders
or a similar event.

	14.3  Reorganizations.  Any other provision of the Plan
notwithstanding, immediately prior to the effective time of a Corporate
Reorganization, the Offering Period then in progress shall terminate and
shares shall be purchased pursuant to Section 8, unless the Plan is assumed
by the surviving corporation or its parent corporation pursuant to the plan
of merger or consolidation.  The Plan shall in no event be construed to
restrict in any way the Company's right to undertake a dissolution,
liquidation, merger, consolidation or other reorganization.

15. Amendment or Discontinuance.  The Board shall have the right to amend,
suspend or terminate the Plan at any time and without notice.  Except as
provided in Section 14, any increase in the aggregate number of shares of
Stock to be issued under the Plan shall be subject to approval by a vote
of the stockholders of the Company.  In addition, any other amendment of
the Plan shall be subject to approval by a vote of the stockholders of the
Company to the extent required by an applicable law or regulation.

16. Execution.  To record the adoption of the Plan by the Board on
July 7, 2000, the Company has caused its authorized officer to execute
the same.
