PROXY STATEMENT FOR 1998 ANNUAL MEETING OF STOCKHOLDERS

INFORMATION CONCERNING SOLICITATION AND VOTING

GENERAL

The enclosed proxy is solicited on behalf of Lam Research Corporation, a
Delaware corporation (the "Company"), for use at the Annual Meeting of
Stockholders to be held Thursday, November 5, 1998 at 11:00 a.m., local time
(the "Annual Meeting"), or for any adjournment thereof, for the purposes set
forth herein and in the accompanying Notice of Annual Meeting of Stockholders.
The Annual Meeting will be held at the principal executive offices of the
Company at 4300 Cushing Parkway, Fremont, California 94538. The Company's
telephone number at that location is (510) 659-0200.

These proxy solicitation materials will be mailed on or about October 8,
1998 to all stockholders entitled to vote at the meeting. A copy of Lam Research
Corporation's 1998 Annual Report to Stockholders accompanies this Proxy
Statement.

RECORD DATE AND PRINCIPAL SHARE OWNERSHIP

Stockholders of record at the close of business on September 24, 1998 are
entitled to receive notice of and to vote at the Annual Meeting. At the record
date, 38,128,300 shares of the Company's Common Stock were outstanding.

REVOCABILITY OF PROXIES

Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Company a written
notice of revocation or a duly executed proxy bearing a later date, or by
attending the Annual Meeting and voting in person. Attending the Annual Meeting
in and of itself may not constitute a revocation of a proxy.

VOTING AND SOLICITATION

Each stockholder voting on the election of directors may cumulate such
stockholder's votes and give one candidate a number of votes equal to the number
of directors to be elected (seven at this meeting) multiplied by the number of
shares held by such stockholder, or distribute the stockholder's votes on the
same principle among as many candidates as the stockholder deems appropriate;
provided that votes cannot be cast for more than seven candidates. However, no
stockholder shall be entitled to cumulate votes for a candidate unless the
candidate's name has been placed in nomination prior to the voting. On all other
matters, each share has one vote.

Votes cast by proxy or in person at the Annual Meeting will be tabulated by
the Inspector of Elections (the "Inspector"). The Inspector will also determine
whether or not a quorum is present. The seven candidates for election as
directors at the Annual Meeting who receive the highest number of affirmative
votes will be elected. The authorization of the 1999 Purchase Plan, as defined
below, will require the affirmative vote of a majority of the shares of the
Company's Common Stock present or represented and entitled to vote at the Annual
Meeting. The ratification of the independent auditors for the Company for the
current year will require the affirmative vote of a majority of the shares of
the Company's Common Stock present or represented and entitled to vote at the
Annual Meeting.

In general, Delaware law also provides that a quorum consists of a majority
of the shares entitled to vote and present or represented by proxy at the
meeting. The Inspector will treat abstentions as shares that are present or
represented and entitled to vote for purposes of determining the presence of a
quorum, but will not treat abstentions as votes in favor of approving any matter
submitted to the stockholders for a vote. Thus, abstentions have the same effect
in this regard as negative votes. Any proxy which is properly dated, executed

1
<PAGE> 5

and returned using the form of proxy enclosed will be voted at the Annual
Meeting in accordance with the instructions of the stockholder. If no specific
instructions are given, the shares will be voted for the election of directors,
for authorization of the 1999 Purchase Plan, for ratification of the appointment
of the designated independent auditors and, with respect to any other matter or
matters that may come before the meeting, as the proxy holders deem advisable in
accordance with their best judgment. If a broker indicates on the enclosed proxy
or its substitute that it does not have discretionary authority as to certain
shares to vote on a particular matter ("broker non-votes"), those shares will
not be considered as present or represented with respect to that matter. Shares
as to which proxy authority has been withheld with respect to any matter will
not be considered as present or represented with respect to that matter. The
Company believes that the tabulation procedures to be followed by the Inspector
are consistent with the general statutory requirements in Delaware concerning
voting of shares and determination of a quorum.

The cost of soliciting proxies will be borne by the Company. The Company
has retained the services of ChaseMellon Shareholder Services ("ChaseMellon") to
act as agent in the solicitation of proxies from bankers, bank nominees and
other institutional owners. The Company estimates that it will pay ChaseMellon a
fee of approximately $6,500 for its services and will reimburse ChaseMellon for
certain out-of-pocket expenses. The Company may reimburse brokerage firms and
other persons representing beneficial owners of shares for their expenses in
forwarding solicitation material to such beneficial owners. Proxies may also be
solicited by certain of the Company's directors, officers and regular employees,
without additional compensation, personally or by telephone or telegram.

STOCKHOLDER PROPOSALS AND NOMINATIONS

Stockholders of the Company may from time to time submit proposals which
they believe should be voted on at the Annual Meeting or nominate persons for
election to the Board of Directors. In accordance with the Company's bylaws, any
such proposal or nomination must be submitted in writing to the Secretary of the
Company not less than 60 days nor more than 90 days prior to the date of the
Annual Meeting of Stockholders. The submission must include certain specified
information concerning the proposal or nominee, as the case may be, and
information about the proponent and the proponent's ownership of Common Stock of
the Company. Proposals or nominations that do not meet these requirements will
not be entertained at the Annual Meeting. The Secretary should be contacted in
writing at the address on the first page of this Proxy Statement to make any
submission or to obtain additional information as to the proper form and content
of submissions.

STOCKHOLDER PROPOSALS FOR INCLUSION IN THE COMPANY'S 1999 PROXY STATEMENT

Pursuant to applicable rules under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), some stockholder proposals may be eligible for
inclusion in the Company's 1999 Proxy Statement. Any such proposal must be
received by the Company no later than June 7, 1999. Stockholders interested in
submitting such a proposal are advised to contact counsel familiar with the
detailed requirements of the applicable securities rules.

PROPOSAL NO. 1
ELECTION OF DIRECTORS

NOMINEES

A board of seven directors is to be elected at the Annual Meeting. The
bylaws of the Company provide that the number of directors shall be fixed at
seven. The proxies cannot be voted for a greater number of persons than the
seven nominees named below. Unless otherwise instructed, the proxy holders will
vote the proxies received by them for the Company's seven nominees named below,
all of whom are currently directors of the Company. If any nominee of the
Company should decline or be unable to serve as a director as of the time of the
Annual Meeting, the proxies will be voted for any substitute nominee whom shall
be designated by the present Board of Directors to fill the vacancy. In the
event that additional persons are nominated for

2
<PAGE> 6

election as directors, the proxy holders intend to vote all proxies received by
them in such a manner in accordance with cumulative voting as will assure 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.
Discretionary authority to cumulate the votes held by the proxy holders is
solicited by this Proxy Statement. The Company is not aware of any nominee who
will be unable or will decline to serve as a director. The term of office of
each person elected as a director will continue until the next Annual Meeting of
Stockholders, or until a successor has been elected and qualified.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" EACH OF
THE SEVEN NOMINEES FOR DIRECTOR SET FORTH BELOW.

DIRECTOR COMPENSATION

Directors who are not employees of the Company receive annual retainers of
$15,000; meeting fees of $1,000 for each Board of Directors meeting attended,
plus reimbursement for reasonable travel expenses; fees of $500 for each
telephonic Board meeting (aggregate fees for Board meetings not to exceed $8,000
per fiscal year); committee meeting fees of $500 per meeting, plus reimbursement
for reasonable travel expenses; and fees of $250 for each telephonic committee
meeting (with no aggregate fee limit for committee meetings). In addition, each
person who is a non-employee director is automatically granted on the first
business day of each calendar year an option to purchase 6,000 shares of the
Company's Common Stock under the Company's 1991 Incentive Stock Option Plan or
1997 Stock Incentive Plan, at a price per share equal to the fair market value
of one share of the Company's Common Stock on that date. Each option has a term
of ten years ("Option Term") and is immediately exercisable. As amended, and
effective as of June 30, 1998, the plans provide that unexercised options may be
exercisable for specified periods following termination of director status,
whether by death, disability or retirement, determined by years of service as a
director to the Company.*

- ---------------

* As amended and restated, the 1991 Incentive Stock Option Plan and the
1997 Stock Incentive Plan provide that if a non-employee director's continuous
status as an outside director terminates as a result of his or her disability or
death, he or she may exercise his or her options within 12 months from the date
of termination (in the case of disability), or have them exercised within 12
months following the date of death by the director's estate or by a person who
acquired the right to exercise the options by bequest or inheritance. In the
event a non-employee director retires, the director's length of service as a
director shall determine the time period for exercising options: for
non-employee directors with less than one year of service prior to retirement,
the director may exercise his or her options at any time within three months
following retirement; for non- employee directors with more than one year but
less than three years of service prior to retirement, the director may exercise
his or her options at any time within six months following retirement; for
non-employee directors with more than three years but less than five years of
service prior to retirement, the director may exercise his or her options at any
time within 12 months following retirement; and for non-employee directors with
more than five years of service prior to retirement, the director may exercise
his or her options at any time within 18 months following retirement. In no
event shall the options be exercisable after expiration of the Option Term. If
the options are not exercised (to the extent they were entitled to be exercised)
within the time specified above, the options shall terminate.

Mr. Emerick's deferred compensation plan in certain circumstances. The
Company's matching contributions paid to Mr. Emerick are based on the
Company's performance and the amount of his deferrals for the preceding
fiscal years. No matching contributions will be made by the Company
following years in which the Company was not profitable. The amount of the

STOCK PLANS

1984 Incentive Stock Option Plan; 1991 Incentive Stock Option Plan; and 1997
Stock Incentive Plan.

The Company's 1984 Incentive Stock Option Plan (the "1984 Option Plan") and
1991 Incentive Stock Option Plan (the "1991 Option Plan") permit the grant of
both "incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), as well as nonstatutory stock
options. Only employees (including employees of any company in which the Company
owns directly or indirectly at least 50% of the voting shares) may receive
incentive stock options, while employees, paid consultants and, in certain
limited instances, outside directors, may receive nonstatutory stock options. On
August 5, 1997, the stockholders approved the 1997 Stock Incentive Plan (the
"1997 Option Plan"). The 1997 Option Plan provides for the grant of incentive
stock options, nonstatutory stock options, restricted stock, deferred stock and
performance share awards to participating officers, directors, employees,
consultants and advisors of the Company and its subsidiaries. Initially, a total
of 3,000,000 shares of Common Stock have been reserved for issuance under the
1997 Option Plan. The number of shares to be issued under the 1997 Option Plan
will automatically increase each calendar quarter subject to certain provisions
and restrictions set forth in the 1997 Option Plan and shall in no event exceed
5,000,000 shares. As described above, the 1991 and 1997 Option Plans were
amended and restated, effective June 30, 1998, with respect to the
exercisability of options granted to non-employee directors.

A total of 9,650,000 shares of Common Stock have been reserved for issuance
under the 1984, 1991 and 1997 Lam Option Plans (the "Option Plans"). As of
September 1, 1998, options to purchase 3,598,709 shares had been exercised (of
which unexercised options for 22,165 shares have since expired), options to
purchase 5,223,946 shares were outstanding at an average exercise price of
$32.27 per share, and 805,180 shares remain available for future grant under the
Option Plans. No restricted stock, deferred stock or performance share awards
had been granted under the 1997 Option Plan as of September 1, 1998. As of
September 1, 1998, no shares remain available for issuance under the 1984 Option
Plan; however, as of September 1, 1998, 513,702 shares under the 1991 Option
Plan and 291,478 shares under the 1997 Option Plan remain available for grant.

During fiscal 1998, the Company granted options to purchase 1,150,000
shares to all named executives as a group (7 persons), at an average exercise
price of $47.81, options to purchase 30,000 shares to all directors serving in
fiscal 1998 who were not named executives, as a group (five persons), at an
average exercise price of $29.875, and options to purchase 2,200,678 shares to
all employees in fiscal 1998 as a group (excluding named executives and
directors), at an average exercise price of $33.48.

1984 Employee Stock Purchase Plan

The 1984 Employee Stock Purchase Plan (the "1984 Purchase Plan") is
implemented by periodic six-month offerings. As of September 1, 1998,
approximately 1,669,017 shares had been issued under the 1984 Purchase Plan.
Effective September 18, 1998, the last date a purchase of shares was effected by
operation of the 1984 Purchase Plan, approximately 368,483 additional shares
were issued, exhausting entirely the shares reserved and available under the
plan for issuance. As a result, all future offerings have been suspended. The
1984 Purchase Plan is administered by the Board of Directors of the Company or
by a committee appointed by the Board. Employees of the Company or any
majority-owned subsidiary, including officers, are eligible to participate if
they are customarily employed by the Company for at least 20 hours per week and
for more than five months per calendar year. The 1984 Purchase Plan currently
permits eligible employees to purchase Common Stock through payroll deductions
(which may not exceed 10% of an employee's base compensation) at 85% of the fair
market value thereof at the beginning or end of each offering period, whichever
is lower. Employees may end their participation in an offering at any time
during the offering period and participation ends automatically on termination
of employment with the Company.

Performance-Based 1996 Restricted Stock Plan

In 1995, the Company adopted a Performance-Based Restricted Stock Plan,
which was implemented on January 1, 1996 (the "1996 Restricted Stock Plan"). As
of September 1, 1998, approximately 22,606 shares (of the 150,000 shares
reserved for issuance) had been issued under the 1996 Restricted Stock Plan and
remain outstanding, and 127,394 remain available for issuance. The 1996
Restricted Stock Plan is adminis-
9
<PAGE> 13

tered by the Board of Directors or by a committee appointed by the Board, and is
designed to reward executives based on achievement of certain predetermined
goals, which include overall corporate results, business unit performance, and
certain qualitative factors such as organization and management development.
Such goals are formula-based so that 80% of the award is made on performance
against financial objectives. Once performance has been measured against
objectives, a stock award is granted based on the fair market value of the
Company's stock at the close of the applicable quarter. The award vests 100% at
the end of five years. If an executive leaves the Company during the five-year
period following the date of award, any unvested shares are forfeited.

OnTrak Stock Options and Employee Stock Purchase Plan Rights

Pursuant to the Merger, a total of 3,423,750 shares of the Company's Common
Stock was reserved for issuance upon the exercise of stock options held by
OnTrak directors, officers and employees. As of September 1, 1998, options to
purchase 820,850 shares had been exercised and options to purchase 1,440,408
shares were outstanding at an average exercise price of $17.78 per share. By
operation of the terms of the Merger, upon consummation of the Merger on August
5, 1998, no more options could be issued under the OnTrak stock option plan.

In addition, a total of 90,000 shares of the Company's Common Stock was
reserved for issuance to OnTrak employees who were participating in OnTrak's
employee stock purchase plan during the purchase period in which the Merger was
consummated. As of September 1, 1998, 51,189 shares remain available for
purchase under the OnTrak employee stock purchase plan. The OnTrak employee
stock purchase plan is scheduled to terminate, and will not be able to issue
shares, following completion of the current stock purchase period on January 31,
1999.

See Proposal No. 2 -- "Adoption and Approval of Lam 1999 Employee Stock
Purchase Plan," below.

(2) The "potential realizable value" shown represents hypothetical gains based
on assumed annual compound stock price appreciation of 5% and 10% from the
date of grant through the full 10-year option term, net of exercise price,
but before taxes associated with exercise. The amounts represent certain
assumed rates of appreciation only, based on the Securities and Exchange
Commission rules. Actual gains, if any, on stock option exercises depend on
the future performance of the Common Stock, overall market conditions

and the option holder's continued employment through the vesting period. The
amounts reflected in this table may not necessarily be achieved and do not
reflect the Company's estimate of future stock price growth.
(3) The options in this table were granted under the 1991 and 1997 Lam Option
Plans and have a ten-year expiration date. With respect to the vesting and
exercisability of the granted options, the respective option agreements
executed by the named executives vary and generally provide as follows:
(a) One-fifth ( 1/5) of the options shall vest and become exercisable one
year following the date of grant, and an additional one-sixtieth
( 1/60) of the options shall vest and become exercisable cumulatively
at the end of each of the thirteenth through sixtieth months of the
employment period, until all such options have vested and become
exercisable;
(b) Twelve-forty-eighths ( 12/48) of the options shall vest and become
exercisable one year following the date of grant and an additional one
forty-eighth ( 1/48) of the shares shall vest and become exercisable
cumulatively at the end of each full month thereafter, until all such
options shares have vested and become exercisable.
(c) One-fourth ( 1/4) of the options shall vest and become exercisable on
January 1, 1999, and an additional one-fourth ( 1/4) of the options
shall vest and become exercisable annually thereafter, such that all
such options are vested and exercisable no later than January 1, 2002;
(d) One-third ( 1/3) of the options shall vest and become exercisable one
year following the date of grant, and an additional one third ( 1/3) of
the options shall vest and become exercisable cumulatively at the end
of each year thereafter, until all such options have vested and become
exercisable; and
(e) One-forty-eighth ( 1/48) of the options shall vest and become
exercisable cumulatively at the end of each full month beginning on
January 1, 1999, until all such options have vested and become
exercisable.

EMPLOYMENT AND TERMINATION AGREEMENTS,
CHANGE OF CONTROL ARRANGEMENTS AND RETIREMENT BENEFITS

EMPLOYMENT AGREEMENT WITH JAMES W. BAGLEY

On July 1, 1997, the Company signed an employment agreement with James W.
Bagley which became effective on August 6, 1997, the day following consummation
of the Merger (the "Bagley Agreement"). The term of the Bagley Agreement is five
years, unless earlier terminated by the Company or Mr. Bagley. The Bagley
Agreement provides for a base salary at the annualized rate of $100,000. Mr.
Bagley is not entitled to participate in any performance bonus plan of the
Company, unless otherwise determined by the Board of Directors. As an incentive
to joining the Company, Mr. Bagley was granted non-qualified stock options to
purchase 250,000 shares of Common Stock (the "Incentive Options"). In lieu of
additional base compensation or participation in performance bonus plans, the
Company granted Mr. Bagley non-qualified stock options to purchase 225,000
shares of Common Stock (the "Base Options"). Under the Bagley Agreement, Mr.
Bagley is also entitled to participate in the Company's Executive Deferred
Compensation Plan and other benefit plans and compensation programs generally
maintained for other key executives of the Company.

11
<PAGE> 15

In the event of a change in control of the Company or the involuntary
termination of Mr. Bagley without cause, all unvested Incentive Options will
automatically be accelerated in full so as to become fully vested. Mr. Bagley
will have two years from the date of termination in which to exercise such
options. If Mr. Bagley's employment is involuntarily terminated without cause on
or after the first anniversary of the effective date of the Bagley Agreement, he
will be entitled to receive a lump sum payment of $100,000, and any unvested
portion of the Base Options that would have vested within the one-year period
following the date of such termination (which then vested options may be
exercised within two years of termination).

The Bagley Agreement provides that for a period of 12 months following Mr.
Bagley's termination of employment with the Company (other than through
expiration of the Bagley Agreement), Mr. Bagley may not perform services
respecting certain aspects of semiconductor manufacturing equipment and/or
software for anyone other than the Company, and may not solicit any of the
Company's employees to become employed by any other business enterprise.

EMPLOYMENT AGREEMENT WITH ROGER D. EMERICK

In July 1996, the Company signed an employment agreement with Roger D.
Emerick, then Chairman of the Board and Chief Executive Officer of the Company.
The agreement, which became effective on July 1, 1996, provided that Mr. Emerick
was to serve as Chief Executive Officer of the Company for a period of two
years, which period extended automatically (but not beyond June 30, 2002),
unless terminated by the Company or Mr. Emerick with at least 180 days' advance
notice. In the event Mr. Emerick ceased to serve as the Chief Executive Officer
of the Company, Mr. Emerick was to serve as a consultant to the Company through
June 30, 2002. The agreement was amended on June 26, 1997 to provide for the
continued employment of Mr. Emerick following the appointment of James W. Bagley
as Chief Executive Officer of the Company, and again to reflect Mr. Emerick's
resignation as Chairman of the Board of Directors, effective September 1, 1998,
and continued service as an employee of the Company (as amended, the "Emerick
Agreement"). As provided in the Emerick Agreement, Mr. Emerick's employment with
the Company is to continue until June 30, 1998, which period automatically
extends (but not beyond June 30, 2002) unless terminated by the Company or Mr.
Emerick with at least 180 days' advance notice, during which time Mr. Emerick
shall perform such strategic, senior level duties and responsibilities as the
Company's Chief Executive Officer may assign to him. Upon expiration of Mr.
Emerick's employment period, Mr. Emerick shall continue to serve as a consultant
to the Company through June 30, 2002 (unless such consultancy is otherwise
terminated, as provided in the Emerick Agreement).

The Emerick Agreement provided for an initial annual base salary of
$621,857 during the employment period, which was to be reviewed at least
annually. Effective September 1, 1998, the salary was adjusted to an annualized
rate equivalent to $33,333 per month. The Emerick Agreement also provides for an
annual performance bonus of up to 50% of base salary based on attainment of
certain performance targets established by the Company's Board of Directors. For
services as a consultant, the Company will pay Mr. Emerick a monthly consulting
fee of $33,333. Mr. Emerick also participates in all of the incentive
compensation plans and programs generally available to the senior management of
the Company, as well as any employee benefit plan maintained by the Company for
its employees. If Mr. Emerick's employment is involuntarily terminated without
cause, he will be entitled to receive his targeted bonus amount, plus an amount
equal to the consulting fee, for the period beginning on the date of termination
and ending June 30, 2002, subject to a maximum of 48 months, as well as certain
other benefits. In addition, upon involuntary termination without cause or a
change in control of the Company, the unvested portion of Mr. Emerick's stock
options and restricted stock will automatically be accelerated in full so as to
become fully vested. The Emerick Agreement provides that for a period of 24
months following Mr. Emerick's termination of employment with the Company, Mr.
Emerick may not perform services for any direct competitor of the Company, and
may not solicit any of the Company's employees to become employed by any other
business enterprise.

In July, 1998, Mr. Emerick petitioned the Board to receive an early
distribution of benefits under the Company's Elective Deferred Compensation
Plan. Beginning September 1, 1998, Mr. Emerick is to receive a monthly
distribution of $8,000 of benefits due him under the plan.

EMPLOYMENT AGREEMENT WITH STEPHEN G. NEWBERRY

On August 5, 1997, the Company signed an employment agreement with Stephen
G. Newberry (the "Newberry Agreement"). The term of the Newberry Agreement is
five years, unless earlier terminated by the Company or Mr. Newberry. The
Newberry Agreement provides for a base salary at the annualized rate of
$450,000, which is to be reviewed at least annually by the Board of Directors
for possible increases. Mr. Newberry is not entitled to participate in any
performance bonus plan of the Company, unless otherwise determined by the Board
of Directors. As an incentive to joining the Company, Mr. Newberry was granted
non-qualified stock options to purchase 200,000 shares of Common Stock (the
"Incentive Options"). In lieu of additional base compensation or participation
in performance bonus plans, the Company granted Mr. Newberry non-qualified stock
options to purchase 100,000 shares of Common Stock (the "Base Options"). Under
the Newberry Agreement, Mr. Newberry is also entitled to participate in the
Company's Executive Deferred Compensation Plan and other benefit plans and
compensation programs generally maintained for other key executives of the
Company. Mr. Newberry also received a deferred signing bonus in the amount of
$500,000, the entire amount of which was held in a deferred compensation
account, pursuant to the Company's Elective Deferred Compensation Plan, with Mr.
Newberry's interest in the account vesting in equal installments of 25% on each
of the first four anniversaries following August 5, 1997.

In the event of a change in control of the Company or involuntary
termination without cause, all unvested Incentive Options will automatically be
accelerated in full so as to become fully vested, as will any Base Options that
would have vested within the one year period following the date of such
termination. Mr. Newberry will have two years from the date of termination in
which to exercise such options. If Mr. Newberry's employment is involuntarily
terminated without cause on or after the first anniversary of the effective date
of the Newberry Agreement, he will be entitled to receive a lump sum payment
equal to one times his then annual base compensation.

The Newberry Agreement provides that for a period of 12 months following
Mr. Newberry's termination of employment with the Company (other than through
expiration of the Newberry Agreement), Mr. Newberry may not solicit any of the
Company's employees to become employed by any other business enterprise.

AGREEMENT WITH RAYMOND L. DEGNER

Raymond L. Degner retired from his position as Senior Vice President,
effective February 28, 1998. Mr. Degner signed an agreement regarding his change
in employment status dated January 27, 1998 (the "Degner Agreement"). Pursuant
to the terms of the Degner Agreement, Mr. Degner commenced a fully paid Leave of
Absence ("LOA") from the Company on February 28, 1998, which leave will end on
April 12, 1999. Pursuant to the Degner Agreement, Mr. Degner is required to make
himself available during the term of the Degner Agreement for consultation with
the President and Chief Operating Officer, Stephen G. Newberry, which periods of
consultation (if any) would automatically extend the LOA term. During the LOA
term, Mr. Degner continues to receive his annual base salary and benefits, and
any granted stock options will continue to vest. Further, at the end of the LOA
term Mr. Degner's restricted stock awards through the third quarter of fiscal
1998 are to be fully vested and paid in accordance with the Performance Based
Restricted Stock Plan. However, Mr. Degner is not eligible for additional stock
options, nor is he eligible to participate in the Company's Executive Bonus
Plan.

CHANGE OF CONTROL ARRANGEMENTS

In addition to the change of control provisions in the foregoing
agreements, the Option Plans and 1984 Purchase Plan provide that, upon a merger
of the Company with or into another corporation, or the sale of substantially
all of the assets of the Company, each outstanding option or right to purchase
Common Stock shall be assumed, or an equivalent option or right substituted by
the successor corporation or a parent or subsidiary of the successor
corporation. In the event that the successor corporation does not agree to
assume the option or right, or substitute an equivalent option or right, some or
all of the options granted under the Option Plans shall be fully exercisable for
a period of 15 days and all of the rights granted under the 1984

13
<PAGE> 17

Purchase Plan shall be fully exercisable for a period of 30 days, from the date
of notice by the Board of Directors. Following the expiration of such periods,
the options and rights will terminate.

RETIREMENT MEDICAL AND DENTAL BENEFITS

The Board of Directors approved a plan in July 1996 allowing executives who
retire from the Company to continue to participate in the Company's group
medical and dental plans after retirement. Additionally, in July 1998, the Board
amended the Lam Research Corporation Executive Deferred Compensation Plan to
provide that any participant 55 years or older may petition the Board for an
early distribution of benefits under the Plan. Any such early distribution would
not effect a participant's ability to continue to participate and earn benefits
under the Plan.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In April 1996, Roger D. Emerick, then Chairman of the Board and Chief
Executive Officer, borrowed $600,000 from the Company pursuant to a promissory
note bearing interest at 5.05% per annum. In April 1997, and again in April,
1998, the loan was renewed by the Company. As of September 1, 1998, $600,000 in
deferred principal plus deferred accrued interest remains outstanding.

In connection with her initial and continued employment, the Company made
Mercedes Johnson, Vice President, Finance and Chief Financial Officer, a loan in
May 1997, in the amount of $150,000. The loan bears no interest and is payable
in equal annual installments over a four-year period. On the each of the first
four anniversaries of Ms. Johnson's employment, the Company will pay Ms. Johnson
a bonus in the amount of $37,500, which amount will be used to offset the loan.
In the event Ms. Johnson terminates her employment with the Company, she will be
required to pay the outstanding balance of the loan in accordance with its
terms. As of September 1, 1998, $112,500 remains due and owing under the loan
(and subject to future offset).

In connection with his initial and continued employment, the Company made
Craig Garber, Vice President and Treasurer, a loan in September 1997, in the
amount of $60,000. The loan bears interest at 6% per annum, which is forgivable
upon complete repayment of the loan. The loan is payable in equal installments
over a four-year period. On each of the first four anniversaries of Mr. Garber's
employment, the Company will pay Mr. Garber a bonus in the amount of $15,000,
which amount will be used to offset the loan. In the event Mr. Garber terminates
his employment with the Company, he will be required to pay the outstanding
balance of the loan in accordance with its terms. As of September 1, 1998,
$60,000 remains due and owing under the loan (and subject to future offset).

In connection with his continued employment, the Company made Rick
Friedman, Vice President, Worldwide Sales and Service in fiscal 1998, a loan in
the amount of $150,000. The loan bears interest at the rate of 6% per annum. All
unpaid principal and accrued interest are due by May 11, 2002 (with no penalty
under the terms of the loan for pre-payment). A deed of trust to certain real
property is pledged as security for the loan. As of September 1, 1998, $150,000,
plus accrued interest, remains due and owing under the loan.

On March 28, 1997, the Company invested $4 million in an investment limited
partnership, Tribridge International, L.P. (the "Partnership"), the general
partner of which is a limited liability company, Tribridge Venture Management
LLC (the "General Partner"). Roger D. Emerick, Grant M. Inman and Osamu Kano,
each of whom was during fiscal 1998 a director of the Company, were the sole
owners of the General Partner. The Partnership was organized for the purpose of
investing in emerging technology companies. Pursuant to the terms of the
partnership agreement, the General Partner would be paid an annual management
fee of 1% of the Partnership's committed capital contributions. In addition, the
General Partner had a carried interest in the Partnership of 4% of the $12.5
million in capital contributions. On April 23, 1997, the Partnership made an
investment of $2 million in Optical Specialties, Inc. ("OSI"), a company of
which Jack R. Harris was Chairman, Chief Executive Officer and President. Osamu
Kano was also a director of OSI. David G. Arscott, along with Messrs. Harris and
Kano, all hold shares of OSI and were, at the time of the Partnership's
investment and during fiscal 1998, all directors of the Company. Effective July
1998, the Company withdrew

14
<PAGE> 18

its interest and participation in the Partnership, receiving a distribution of
its share of uncommitted capital and retaining, by assignment from the
Partnership, a residual interest in investments of the Partnership as of the
date of the Company's withdrawal (including a residual interest in OSI).

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Osamu Kano, director of the Company from 1987 through fiscal 1998, was a
member of the Compensation Committee in fiscal 1993 and 1994. Mr. Kano is
currently the Chairman of Lam Research Co., Ltd. in Japan, a subsidiary of the
Company, and served as the Company's Senior Vice President of Japan Operations
from 1987 to June 1991. As of August 18, 1994, Mr. Kano became a member of the
Audit Committee and no longer served on the Compensation Committee. Effective
October 1, 1998, Mr. Kano has resigned his positions as a Member of the Board of
Directors, and as Chairman of Lam Research Co., Ltd.

Grant M. Inman, a director of the Company since 1981, is a member of the
Compensation Committee. Mr. Inman is currently a stockholder of Tribridge
Venture Management LLC, which is paid an annual management fee of 1% of the
committed capital contributions of Tribridge International, L.P.

Jack R. Harris, a director of the Company since 1982, is a member of the
Compensation Committee. The Company has invested a total of $500,000 to purchase
Series A Preferred Stock and Series E Preferred Stock of OSI in two
transactions. Other outside investors also participated in the transactions. The
latter of the transactions took place on December 14, 1994. As noted above,
Tribridge International, L.P. invested $2 million in OSI on April 23, 1997;
however, the Company no longer holds a direct interest in Tribridge
International, L.P. or OSI. See "Certain Relationships and Related Transactions"
above.

REPORT OF THE COMPENSATION COMMITTEE

Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933, as amended ("Securities
Act"), or the Exchange Act, that might incorporate all or portions of future
filings, including this Proxy Statement, the following Report of the
Compensation Committee, and the Performance Graph below, shall not be
incorporated by reference into any such filings, nor shall they be deemed to be
soliciting material or deemed filed with the Securities and Exchange Commission
("SEC") under the Securities Act or the Exchange Act.

The Compensation Committee (the "Committee") of the Board of Directors,
composed of three non-employee directors, determines and administers the
Company's executive compensation policies and programs.

COMPENSATION POLICIES

One of the Committee's primary goals in setting compensation policies is to
maintain competitive, progressive programs to attract, retain and motivate
high-caliber executives, foster teamwork and maximize the long-term success of
the Company by appropriately rewarding such individuals for their achievements.
Another goal is to provide an incentive to executives to focus efforts on
long-term strategic goals for the Company by closely aligning their financial
interests with stockholder interests. To attain these goals, the Committee has
designed the Company's executive compensation program to include base salary,
annual incentives and long-term incentives.

In formulating and administering the individual elements of the Company's
executive compensation program, the Committee emphasizes planning, implementing
and achieving long-term objectives and strives to use prudent judgment in
establishing performance objectives, evaluating performance and determining
actual incentive awards.

The Committee believes that the Company's executive compensation programs
have met these objectives. The Company has been able to attract and retain the
executive talent necessary to support the corporation and promote long-term
growth. The Company has also been able to reduce the payment of

15
<PAGE> 19

bonuses during those periods, such as in fiscal 1998, in which the Company's
revenue and gross margins decreased.

COMPENSATION COMPONENTS

Base Salary

The Compensation Committee establishes the base salaries of executive
officers, after review of relevant data of other executives with similar
responsibilities from published industry reports and surveys of similarly
situated companies. Accordingly, the Compensation Committee strives to maintain
the Company's annual executive salaries at levels competitive with the market
average base salary of executive officers in similar positions. The market is
comprised of similarly sized high technology companies within and outside the
Company's industry. In addition, a large portion of each executive officer's
compensation may be annual incentives in the form of a cash bonus, provided
certain target performance objectives are met.

Annual Incentives

The more aggressive incentive bonus levels for executives are intended to
provide the appropriate elements of variability and risk. Bonus payments are
tied specifically to targeted corporate performance. The Compensation Committee
will establish a base bonus amount, determined through review of a competitive
market survey for executives at similar levels, which will be incrementally
reduced if the Company does not meet its targeted performance or increased if
the Company exceeds its targeted performance. There is no minimum or maximum
percentage by which a bonus can be reduced or increased.

Long-Term Incentives

Stock Options

The Stock Committee grants stock options to focus an executive's attention
on the long-term performance of the Company and on maximizing stockholder value.
The grant of stock options is closely tied to individual executive performance.
The Stock Committee grants such stock options after a review of various factors,
including the executive's potential contributions to the Company, current equity
ownership in the Company and vesting rates of existing stock options, if any.
Stock options are granted with an exercise price equal to the current fair
market value of the Company's stock, and utilize vesting periods intended to
encourage retention of executive officers. Because of the direct benefit
executive officers receive through improved stock performance, the Stock
Committee believes stock options serve to align the interests of executive
officers closely with those of other stockholders.

Restricted Stock

Restricted stock awards are granted to executives under the Restricted
Stock Plan, which was approved by the Company's stockholders in 1995. The award
of restricted stock is based on the Company's performance measured against
quarterly targets. Because the restricted stock does not vest until five years
after the date of the award, the Restricted Stock Plan is expected to serve as a
retention tool, as well as a means of aligning executive and stockholder
interests.

Deferred Compensation Plan

Another component of the Company's executive compensation program is the
Lam Research Corporation Executive Deferred Compensation Plan (the "Deferred
Plan"), a voluntary, non-tax-qualified, deferred compensation plan that
encourages officers to save for retirement. Under the Deferred Plan,
participants are entitled to defer compensation until retirement, death, other
termination of employment, or until specified dates. As amended by the Board in
July 1998, the Deferred Plan provides that participants 55 years or older may
petition the Board for an early distribution of benefits, which early
distribution would not affect the participant's ability to continue to
participate or earn benefits under the Deferred Plan. Participants receive a
fixed-rate yield based on the average annual interest rate of ten-year United
States Treasury Notes for the previous ten years. An enhanced yield of up to
115% of the fixed-rate yield will be payable in the event of
16
<PAGE> 20

death, retirement under certain circumstances, and termination of employment
after plan participation for a specified number of years. Because the benefits
of the Deferred Plan increase with each year of participation, offering the
Deferred Plan to executives encourages them to stay with the Company.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

The Committee bases the compensation of the Company's Chief Executive
Officer on the policies and procedures described above. In determining the Chief
Executive Officer's base salary and bonus (if any), the Committee examines
compensation levels for other chief executive officers in high technology firms
within and outside the industry. The Committee compares this information to the
relevant performance of such firms relative to the Company's performance.

James W. Bagley

In accordance with the Bagley Agreement, Mr. Bagley, Chief Executive
Officer since August 6, 1997, received a base salary in fiscal 1998 of $100,000.
Mr. Bagley is not entitled to participate in any performance bonus plan of the
Company, unless otherwise determined by the Board of Directors. As an incentive
to joining the Company, Mr. Bagley was granted non-qualified stock options to
purchase 250,000 shares of Common Stock. In lieu of additional base compensation
or participation in performance bonus plans, the Company granted Mr. Bagley
non-qualified stock options to purchase 225,000 shares of Common Stock. See the
discussion of Mr. Bagley's Employment Agreement in "Employment and Termination
Agreements, etc.," above.

Roger D. Emerick

In accordance with the Emerick Agreement, Mr. Emerick, Chief Executive
Officer of the Company until August 6, 1997, received a base salary during
fiscal 1998 of $621,878. Mr. Emerick did not receive a bonus in fiscal 1998. The
Emerick Agreement and Mr. Emerick's current compensation arrangement with the
Company also reflect the Company's desire to retain and motivate him with
long-term incentives. To this end, the Company granted Mr. Emerick 125,000 stock
options in fiscal 1998. Mr. Emerick also has a ten-year deferred compensation
arrangement with the Company, which provides for an increasing portion of
compensation to be paid to Mr. Emerick each year in which the Company is
profitable, and which is scheduled to terminate in 2002 (the "Deferred Plan").
In fiscal 1998, the Company contributed $100,000 to Mr. Emerick's Deferred Plan.
See the Summary Compensation Table, fn. 2, in "Executive Compensation and Other
Information," above.

EFFECT OF SECTION 162(M) OF THE INTERNAL REVENUE CODE

Section 162(m) of the Code generally limits the corporate deduction for
compensation paid to certain executive officers to $1 million, unless the
compensation is performance-based. The Committee has carefully considered the
potential impact of this tax code provision on the Company and has concluded in
general that the best interests of the Company and the stockholders will be
served if certain of the Company's stock-based long-term incentives qualify as
performance-based compensation within the meaning of the Code. It is the
Committee's intention that, so long as it is consistent with the Company's
overall compensation objectives, virtually all executive compensation will be
deductible by the Company for federal income tax purposes.

COMPARATIVE STOCK PERFORMANCE

Set forth below is a line graph comparing the cumulative total stockholder
return on the Company's Common Stock for the last five fiscal years ("LRCX")
against the cumulative total return on the Nasdaq National Market Index (U.S.
companies only) ("NASDAQ") and the Salomon Smith Barney Semiconductor Equipment
Index ("SSB") over the same period. The graph and table assume that the
investment in Lam Common Stock and each index was $100 on July 2, 1993, and that
dividends, if any, were reinvested. This data was furnished by Salomon Smith
Barney. The Nasdaq National Market Index and the Salomon Smith Barney
Semiconductor Equipment Index are based on a calendar year. The Company's return
is based on its fiscal year. The stock price performance shown on the graph is
not necessarily indicative of future price performance.

PROPOSAL NO. 2
ADOPTION AND APPROVAL OF
LAM 1999 EMPLOYEE STOCK PURCHASE PLAN

The Board has adopted, subject to receipt of stockholder approval, the Lam
1999 Employee Stock Purchase Plan (the "1999 Purchase Plan" or "Plan"), which is
intended to replace the 1984 Purchase Plan in order to continue to provide
employees of the Company an opportunity to purchase Lam Common Stock through
accumulated payroll deductions. The number of shares proposed to be reserved for
issuance under the Plan is a maximum of 3,000,000: 1,000,000 shares to be issued
at any time prior to termination of the Plan and an additional share (up to a
total of 2,000,000 additional shares) issued for each share of Lam Common Stock
repurchased by the Company in the public market or in private purchases for use
for this purpose.

18
<PAGE> 22

As of September 1, 1998, 38,124,277 shares of Lam Common Stock were
outstanding, and an aggregate of approximately 8,016,600 shares of Lam Common
Stock were reserved and available for purchase under Lam employee stock purchase
programs and reserved and available for issuance pursuant to outstanding and
future awards under all of Lam stock incentive plans (including options to
purchase Lam Common Stock under OnTrak plans adopted by Lam as a result of the
Merger). Assuming the stockholders approve the adoption of the 1999 Purchase
Plan, this aggregate number would increase to 9,016,600** -- equal to
approximately 19.13% of the total number of shares of Lam Common Stock that
would be outstanding on a fully-diluted basis, as of September 1, 1998.***

The Board has determined that, since the 1984 Employee Stock Purchase Plan
(the "1984 Purchase Plan") has exhausted the number of shares currently reserved
thereunder for issuance, the 1984 Purchase Plan, as a practical matter, no
longer provides a sufficient mechanism to compensate employees and provide
appropriate long-term incentives for continued employment through an ability to
purchase Lam Common Stock. The terms of the 1984 Purchase Plan -- specifically,
those affecting the level of deductions from compensation and the manner of
pricing of stock available for purchase under that plan -- are more restrictive
and less flexible when compared to the terms of comparable employee stock
purchase plans available to employees of competing companies. The Board believes
that the terms of the 1999 Purchase Plan will permit a more flexible approach to
and administration of employee purchases of Lam's Common Stock. Accordingly, the
Board believes that the 1999 Purchase Plan reflects the best interests of Lam
and recommends its approval by stockholders at the Annual Meeting.

PURPOSE

The Lam Board has adopted the 1999 Purchase Plan as part of its policy to
further the long-term growth in Lam's earnings by providing incentives to its
employees, who are or will be responsible for such growth; to facilitate the
ownership of Lam's stock by such individuals, thereby increasing the identity of
their interests with those of Lam's stockholders; and to assist Lam in
attracting and retaining employees with experience and ability by offering an
employee stock purchase plan with terms both attractive and competitive when
compared with the terms of comparable plans offered by companies competing with
Lam in the work force.

The Existing 1984 Employee Stock Purchase Plan

When Lam originally adopted the 1984 Purchase Plan, 112,500 shares of Lam
Common Stock were reserved for issuance thereunder. The 1984 Purchase Plan has
been amended, with stockholder approval, at various times to increase the total
number of shares reserved thereunder; most recently in November 1997 to increase
the number of shares reserved thereunder from 1,687,500 to 2,037,500. As of
September 1, 1998, a total of approximately 368,500 shares of Lam Common Stock
remained authorized but unissued under the 1984 Purchase Plan. All of these
shares, however, were issued to employees as of September 18, 1998 (the most
recent purchase event under the 1984 Purchase Plan). As a consequence, there are
no shares available for future issuance to employees under the 1984 Purchase
Plan.

The 1984 Purchase Plan, by its terms, is currently scheduled to terminate
in 2004.

- ---------------

** Because up to 2,000,000 of the shares reserved under the 1999 Purchase Plan
shall issue thereunder as an equal number of shares of Lam Common Stock are
repurchased by the Company in the public market or in private purchases, these
additional shares are not included in the dilution calculation provided.

*** Under the dilution calculation utilized, the numerator consists of the
aggregate of the shares of Lam Common Stock reserved and available for purchase
under Lam employee stock purchase programs or issuance under Lam stock incentive
plans (including OnTrak plans adopted by Lam as a result of the Merger). The
denominator consists of the sum of the above aggregate and the total number of
outstanding shares of Lam Common Stock as of September 1, 1998.

THE 1999 PURCHASE PLAN

As described below, the 1999 Purchase Plan allows Lam employees (including
officers and members of the Board who are also employees, as well as employees
of designated Lam subsidiaries) to use payroll deductions to purchase Lam Common
Stock on the terms described below.

Plan Administration

The 1999 Purchase Plan will be administered by the Board and/or a committee
appointed by the Board, whose administration, interpretation and application of
the Plan and its terms will be final, conclusive and binding on all
participants. The 1999 Purchase Plan provides that no member of the Board or
committee will be liable for any action or determination taken or made in good
faith with respect to the 1999 Purchase Plan, or any shares purchased or issued
thereunder.

Securities Subject to Plan

There will initially be up to 3,000,000 treasury or authorized but unissued
shares of Lam Common Stock reserved for issuance pursuant to purchases made
under the 1999 Purchase Plan: 1,000,000 shares may be issued at any time before
termination of the Plan, and an additional share (up to a total of 2,000,000
additional shares) may be issued for each share of Lam Common Stock that the
Company repurchases, in the public market or in private purchases, after the
date of Board approval of the Plan, and designates for this purpose. The 1999
Purchase Plan provides that the Administrator may, in its discretion, transfer
shares reserved for issuance under this Plan into a plan of similar terms, as
approved by the Board, providing for the purchase of shares of Common Stock by
employees of subsidiaries designated by the Board where desirable in light of
local or foreign law or foreign administration.

Eligibility and Participation

Any regular Lam employee customarily employed by the Company (or by any
majority-owned subsidiary) for more than 20 hours per week is eligible to
participate in the 1999 Purchase Plan. Officers and members of the Board of
Directors who are eligible employees are also permitted to participate in the
Plan. Upon employment with Lam, an employee may participate in the Plan on a
regular or interim basis beginning on the business day immediately after a
regular or interim purchase date. As of September 1, 1998, approximately 3,300
employees would have been eligible to participate in the 1999 Purchase Plan and
1,675 employees are estimated to have been participating under the 1984 Purchase
Plan.

Eligible employees become participants in the 1999 Purchase Plan by
delivering to the Company prior to the applicable offering date (including
interim purchase dates) a subscription agreement authorizing payroll deductions,
or at such other time as may be determined by the Board. An employee who becomes
eligible to participate in the 1999 Purchase Plan after the commencement of an
offering period may participate on an interim basis until commencement of the
next offering period.

Offering Periods and Dates

The offering periods shall generally be 12 months in duration, to coincide
generally with a calendar year. Within the offering period, there are typically
three dates on which Lam Common Stock may be purchased. In the absence of a
viable 1984 Purchase Plan, the Board has determined that the initial offering
period under the 1999 Purchase Plan will begin on November 6, 1998, immediately
upon adoption of the Plan by the Company's stockholders, and will continue until
December 31, 1999 (a period of approximately 14 months). During this initial
offering period, there will be four dates on which Lam Common Stock may be
purchased by employees. If, on the first business day following a purchase date
(other than the last purchase date of an offering period), the fair market value
of a share of Lam Common Stock is less than the fair market value as of the
first day of the offering period, the terms of the Plan provide that a new
offering period will automatically begin as of that day and all eligible
employees participating in the Plan will be automatically enrolled in the new
offering period (and the old offering period will be terminated). The Board may
alter the duration of the offering periods or the number or timing of the
purchase dates without stockholder approval.
20
<PAGE> 24

Payroll Deductions

The purchase price of the shares is accumulated by payroll deductions
during the offering period. Each employee participating in the Plan may elect to
have up to 15% of regular base compensation (defined in the 1999 Purchase Plan
to include all regular straight-time gross earnings, exclusive of overtime,
shift premium, incentive compensation or payments, or bonuses, commissions or
other payments) deducted and credited to that employee's account under the Plan.
No additional payments or amounts may be credited to an employee's account;
however, an employee may change the rate of payroll deductions or withdraw
entirely from the Plan during any offering period. The Board may alter the level
of allowed payroll deductions without stockholder approval.

Amounts deducted from regular base compensation and credited to a
participating employee's account shall be held as general funds of Lam, and
shall not accrue interest. To the extent that an employee's payroll deductions
exceed the amount required to purchase shares subject to purchase rights, the
excess shall be refunded to the employee without interest.

Purchase of Stock; Exercise of Purchase Right

By electing to participate in the 1999 Purchase Plan, each employee is in
effect granted a right to purchase shares of Lam Common Stock using payroll
deductions accumulated as of each of the purchase dates during any offering
period. However, a participating employee's ability to purchase Lam Common Stock
during any calendar year under any of the Company's stock purchase plans is
limited to $25,000 worth of stock (determined at the time the purchase right is
originally granted). If the number of shares otherwise subject to purchase
rights during an offering period exceeds the number of shares then available
under the 1999 Purchase Plan, a pro rata allocation of the shares shall be made
in as equitable a manner as is practicable. Unless an employee withdraws from
participation in the 1999 Purchase Plan (see "Withdrawal," below), or his or her
participation is otherwise discontinued (see "Termination of Employment,"
below), the employee's right to purchase shares will be exercised automatically
at the end of the purchase date for the maximum number of shares at the
applicable price.

Purchase Price of Lam Common Stock; Taxes on the Acquisition or Disposition
of Stock

On any particular purchase date under the 1999 Purchase Plan, the purchase
price per share will be 85% of the lower of the fair market value of a share of
Common Stock as of (i) the beginning of the offering period, (ii) any
intervening interim offering date (if the employee becomes a participant as of
that date), or (iii) the purchase date. On September 1, 1998, the closing market
price of Lam Common Stock was $12.00, as reported by the Nasdaq National Market.
The fair market value of a share of Lam Common Stock on a given date shall be
the closing price as reported in the Wall Street Journal for such date. If there
is no public trading of Lam Common Stock on a given date, the fair market value
shall be determined by the Plan Administrator in its discretion.

The participating employee shall be responsible for all taxes or other
withholdings required in connection with the acquisition or disposition of stock
purchased under the 1999 Purchase Plan. See "Certain United States Federal
Income Tax Information," below. The participating employee shall not have an
interest or voting right in any shares covered under the 1999 Purchase Plan
prior to purchase.

Ability of the Board or Plan Administrator to Amend the 1999 Purchase Plan

The Board may terminate or amend the 1999 Purchase Plan, or any purchase
right granted thereunder, at any time (except in the event of certain changes in
control of the Company). However, stockholder approval is required for any
amendment to (i) increase the number of shares which may be issued under the
Plan, (ii) change the designation of employees eligible to participate under the
Plan, or (iii) materially increase the benefits which may accrue to employees
participating under the Plan (if, at the time of such amendment, Lam has a class
of securities registered under Section 12 of the Exchange Act).

Term and Termination of Plan

The 1999 Purchase Plan shall become effective upon the earlier of adoption
by the Board or approval by its stockholders, and will continue in effect for a
term of 20 years from January 1, 1999. However, the Board may earlier terminate
the Plan at any time. If the Board terminates the Plan before an employee's
right to purchase shares has been exercised under the 1999 Purchase Plan, any
funds deducted from the employee's base compensation and credited to the
employee's account under the 1999 Purchase Plan shall be refunded.

Withdrawal

An employee may terminate his or her interest in a given offering by
signing and delivering to the Company a notice of withdrawal from the 1999
Purchase Plan. Such withdrawal may be effected at any time prior to the closing
of any offering period or interim purchase date. Any withdrawal by the employee
of accumulated payroll deductions for a given offering automatically terminates
the employee's interest in that offering. The 1999 Purchase Plan does not permit
a partial withdrawal. An employee's withdrawal from an offering does not effect
the employee's eligibility to participate in subsequent offerings under the 1999
Purchase Plan, except for officers subject to Section 16 of the Securities
Exchange Act.

By executing a subscription agreement to participate in the 1999 Purchase
Plan, an employee does not become obligated to make any actual stock purchase;
rather, the subscription agreement merely indicates the employee's election to
have compensation deducted and shares placed under right to him or her for
purchase. However, unless the employee terminates his or her participation, or
withdraws his or her payroll deductions, the right to purchase shares will be
exercised automatically on each purchase date, and for the maximum number of
full shares purchasable with the employee's accumulated payroll deductions.

Termination of Employment

Termination of a participant's continuous status as an employee for any
reason, including retirement or death, cancels his or her participation in the
1999 Purchase Plan immediately. In such event, the payroll deductions credited
to the employee's account will be returned to the employee or, in the case of
death, to the person or persons entitled thereto as specified by the employee in
the subscription agreement. Failure to remain in the continuous employ of the
Company for at least 20 hours per week during the offering period will be deemed
to be a withdrawal from the 1999 Purchase Plan.

Capital Changes

In the event any change is made in the capitalization of the Company, such
as stock splits or stock dividends, which results in an increase or decrease in
the number of shares of Common Stock outstanding without receipt of
consideration by the Company, appropriate adjustments will be made by the
Company to the shares subject to purchase and to the purchase price per share,
subject to any required action by the stockholders of the Company.

In the event of the liquidation or dissolution of the Company, the
then-current offering period shall terminate automatically, unless otherwise
provided by the Board. In the event Lam merges with another corporation (and Lam
stockholders own less than 50% of the surviving entity or its parent), or Lam
sells all or substantially all of its assets, the 1999 Purchase Plan provides
that each outstanding right to purchase shares will be assumed or an equivalent
right will be substituted by the successor corporation; otherwise, the 1999
Purchase Plan provides that all outstanding purchase rights held by Lam
employees may be accelerated.

Nonassignability

No rights or accumulated payroll deductions of an employee under the 1999
Purchase Plan may be pledged, assigned or transferred for any reason, and any
such attempt may be treated by Lam as an election to withdraw from the 1999
Purchase Plan.

22
<PAGE> 26

Reports

Individual accounts are maintained for each participant in the 1999
Purchase Plan. Each participant receives as promptly as practicable after the
end of the offering period a report of his or her account setting forth the
total amount of payroll deductions accumulated, the per share purchase price,
the number of shares purchased and the remaining cash balance, if any.

CERTAIN UNITED STATES FEDERAL INCOME TAX INFORMATION

The 1999 Purchase Plan, and the right of participants to make purchases
thereunder, is intended to qualify under the provisions of Sections 421 and 423
of the Code. Under these provisions, no income will be taxable to a participant
at the time of grant of the right to purchase, or the actual purchase of,
shares. However, upon the employee's disposition of shares purchased under the
1999 Purchase Plan, the participant will generally be subject to tax. Upon
disposition (including by gift), if the shares have been held by the participant
for more than two years after the first day of the offering period and more than
one year after the purchase date of the shares, or upon death of the participant
while holding the shares, the participant will recognize taxable ordinary income
equal to the lesser of (a) the excess of the fair market value of the shares at
the time of the disposition over the purchase price of the shares, or (b) 15% of
the fair market value of the shares on the first day of the offering period (or
interim date on which the employee began to participate in the 1999 Purchase
Plan, if later), and any additional taxable gain on the disposition will be
treated as long-term capital gain. If the shares are disposed of before the
expiration of the holding periods described above, the excess of the fair market
value of the shares on the purchase date over the purchase price will be taxable
as ordinary income, and any gain or loss on such disposition will be treated as
a capital gain or loss. Different rules may apply with respect to participants
subject to Section 16(b) of the Exchange Act. The Company is not entitled to a
deduction for amounts taxable to a participant, except to the extent of ordinary
income reported by the participant on disposition of shares before the
expiration of the holding periods described above.

The foregoing is only a summary of the United States Federal income tax
consequences of the 1999 Purchase Plan to participants and the Company and does
not purport to be complete. Reference should be made to the applicable
provisions of the Code. In addition, the summary does not discuss the income tax
consequences of a participant's death or the income tax laws of any
municipality, state or foreign country in which the participant may reside, and
to which the participant may be subject.

RESTRICTION ON RESALE

Certain officers and directors of the Company may be deemed to be
"affiliates" of the Company, as that term is defined under the Securities Act.
Common Stock acquired under the 1999 Purchase Plan by an affiliate may only be
reoffered or resold pursuant to an effective registration statement or pursuant
to Rule 144 under the Securities Act or another exemption from the registration
requirements of the Securities Act.

VOTE REQUIRED

The affirmative vote of a majority of the votes present in person or by
proxy and entitled to vote at the Lam Annual Meeting is required to approve and
adopt the 1999 Purchase Plan. If the Lam stockholders do not approve the 1999
Purchase Plan, the Board will consider whether to adopt some alternative
arrangement based on its assessment of Lam's needs.

THE BOARD OF DIRECTORS HAS DETERMINED THAT
THE LAM 1999 EMPLOYEE STOCK PURCHASE PLAN IS IN THE
BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND
HAS APPROVED THE LAM 1999 EMPLOYEE STOCK PURCHASE PLAN.
THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS
VOTE "FOR" THE ADOPTION AND APPROVAL OF
THE LAM 1999 EMPLOYEE STOCK PURCHASE PLAN.

<PAGE> 27

PROPOSAL NO. 3
RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

Unless marked to the contrary, proxies received will be voted "FOR" the
ratification of the appointment of Ernst & Young LLP as the independent auditors
for the Company for the current year. Ernst & Young LLP has been the Company's
independent auditors since fiscal year 1981.

The audit services of Ernst & Young LLP during fiscal 1998 included the
examination of the consolidated financial statements of the Company and services
related to filings with the Securities and Exchange Commission ("SEC"), and
other regulatory bodies.

The Audit Committee of the Company meets with Ernst & Young LLP on an
annual or more frequent basis. At such time, the Audit Committee reviews both
audit and non-audit services performed by Ernst & Young LLP for the preceding
year, as well as the fees charged for such services. Among other things, the
Committee examines the effect that the performance of non-audit services may
have upon the independence of the auditors.

A representative of Ernst & Young LLP is expected to be present at the
Annual Meeting and will have an opportunity to make a statement if he or she so
desires. The representative will also be available to respond to appropriate
questions from the stockholders.

Approval of Proposal No. 3 will require the affirmative vote of a majority
of the outstanding shares of Common Stock present or represented and entitled to
vote at the Annual Meeting.

THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS A VOTE "FOR" THE
RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP
AS INDEPENDENT AUDITORS FOR FISCAL 1999.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires the Company's executive officers
and directors and persons who own more than 10% of a registered class of the
Company's equity securities to file an initial report of ownership on Form 3 and
changes in ownership on Form 4 or 5 with the SEC. Executive officers, directors
and greater than 10% stockholders are also required by SEC rules to furnish the
Company with copies of all Section 16(a) forms they file. Specific due dates for
these reports have been established, and the Company is required to disclose in
this Proxy Statement any failure to file such reports on a timely basis. Based
solely on its review of the copies of such forms received by it, or written
representations from certain reporting persons, the Company believes that all of
these requirements were satisfied during the last fiscal year.

OTHER MATTERS

The Company knows of no other matters to be submitted at the meeting. If
any other matters properly come before the meeting, it is the intention of the
persons named in the enclosed form of Proxy to vote the shares they represent as
the Board of Directors may recommend.

24
<PAGE> 28

It is important that your stock be represented at the meeting, regardless
of the number of shares which you hold. You are, therefore, urged to execute and
return, at your earliest convenience, the accompanying proxy card in the
envelope which has been enclosed.

thereunder; unless the Administrator makes a contrary determination, the

Section 5(a) of this Plan.

Section 5, an Employee shall not be eligible to participate in this Plan during
an Offering Period to the extent that (i) immediately after the grant of a

outstanding purchase rights to purchase stock possessing five percent or more of
the total combined voting power or value of all classes of stock of the Company
or of any Subsidiary, or (ii) the grant of a Purchase Right on an Offering Date
or Interim Offering Date would permit the Employee's rights to purchase stock
under all employee stock purchase plans of the Company and its Subsidiaries to
accrue at a rate that exceeds $25,000 of fair market value of such stock
(determined at the date of grant of those purchase rights) for each calendar
year in which the purchase rights would be outstanding at any time.

4. Offering Periods.

Unless otherwise determined by the Administrator:

(a) the first Offering Period under this Plan shall begin as
of November 6, 1998 and shall end on December 31, 1999;

(b) the duration of each Offering Period (other than the first
Offering Period) shall be 12 months (measured from the first business day of the
first month to the last business day of the 12th month;

(d) a new Offering Period shall begin, and the old Offering
Period shall terminate, on the first business day after an Exercise Date (other
than the last Exercise Date of an Offering Period) if the fair market value

than the fair market value of a share of Common Stock on the Offering Date of
the Offering Period; and

(e) an Offering Period shall terminate on the date that there
are no Participants enrolled in it.

5. Participation.

(a) An Employee may become a Participant in this Plan by
completing a subscription agreement, in such form or forms as the Administrator
may approve from time to time, and filing it with the Company's payroll office
within 15 days before the applicable Offering Date or Interim Offering Date,
unless another time for filing the subscription agreement is set by the
Administrator for all Employees with respect to a given Offering Period. The
subscription agreement shall authorize payroll deductions pursuant to this Plan
and shall have such other terms as the Administrator may specify from time to
time.

(b) At the end of an Offering Period, each Participant in the
Offering Period who remains an Employee shall be automatically enrolled in the
next succeeding Offering Period

<PAGE> 32

(a "Re-enrollment") unless, in a manner and at a time specified by the
Administrator, but in no event later than the day before the Offering Date of
such succeeding Offering Period, the Participant notifies the Administrator in
writing that the Participant does not wish to be re-enrolled. Re-enrollment
shall be at the withholding percentage specified in the Participant's most
recent subscription agreement unless the Participant changes that percentage by
timely written notice. No Participant shall be automatically re-enrolled whose
participation has terminated by operation of Section 10 of this Plan.

(c) If an Offering Period commences pursuant to Section 4(d)
of this Plan, each Employee on the Offering Date of that Offering Period shall
automatically become a Participant in the commencing Offering Period.
Participation shall be at the withholding percentage specified in the
Participant's most recent subscription agreement, unless the Participant notice
changes that percentage by timely written notice. If the Participant has no
subscription agreement on file, Participation shall be at a 0% withholding rate
until changed by the Participant. No Participant shall be automatically
re-enrolled whose participation has terminated by operation of Section 10 of
this Plan.

6. Payroll Deductions.

(a) Each Participant shall have withheld a percentage of his
or her Compensation received during an Offering Period. Withholding shall be in
whole percentages, up to a maximum (not to exceed 15%) established by the
Administrator from time to time, as specified by the Participant in his or her
subscription agreement. Payroll deductions for a Participant during an Offering
Period shall begin with the first payroll following the Offering Date or Interim
Offering Date and shall end on the last Exercise Date of the Offering Period,
unless sooner terminated by the Participant as provided in Section 10 of this
Plan.

(b) All payroll deductions made by a Participant shall be
credited to the Participant's account under this Plan. A Participant may not
make any additional payments into such account.

(c) A Participant may change the rate of his or her payroll
deductions during an Offering Period by filing with the Administrator a new
subscription agreement authorizing the change. The change shall take effect 15
days after the Administrator's receipt of the new subscription agreement, except
that increases in rate shall take effect on the day after the first Exercise
Date on or after the 15th day.

7. Purchase Rights.

(a) Grant of Purchase Rights. On the Offering Date, or (if
applicable) Interim Offering Date of each Offering Period, the Participant shall
be granted a Purchase Right to purchase (at the per-share price) during the
Offering Period the number of shares of Common Stock determined by dividing (i)
$25,000 multiplied by the number of (whole or part) calendar years in the
Offering Period by (ii) the fair market value of a share of Common Stock on the
Offering Date or Interim Offering Date.

<PAGE> 33

(b) Terms of Purchase Rights. Except as otherwise determined
by the Administrator, each Purchase Right shall have the following terms:

(i) The per-share price of the shares subject to a
Purchase Right shall be 85% of the lower of the fair
market values of a share of Common Stock on (a) the
Offering Date, or Interim Offering Date, on which the
Purchase Right was granted and (b) the Exercise Date.
The fair market value of the Common Stock on a given
date shall be the closing price as reported in the
Wall Street Journal; provided, however, that if there
is no public trading of the Common Stock on that
date, then fair market value shall be determined by
the Administrator in its discretion.

(ii) Payment for shares purchased by exercise of Purchase
Rights shall be made only through payroll deductions
in accordance with Section 6 of this Plan.

(iii) Upon purchase or disposition of shares acquired by
exercise of a Purchase Right, the Participant shall
pay, or make provision adequate to the Administrator
for payment of, all tax (and similar) withholdings
that the Administrator determines, in its discretion,
are required due to the acquisition or disposition,
including without limitation any such withholding
that the Administrator determines in its discretion
is necessary to allow the Company and its
Subsidiaries to claim tax deductions or other
benefits in connection with the acquisition or
disposition.

(iv) During his or her lifetime, a Participant's Purchase
Right is exercisable only by the Participant.

(v) The Purchase Rights will in all respects be subject
to the terms and conditions of this Plan, as
interpreted by the Administrator from time to time.

8. Exercise Dates; Purchase of Shares; Refund of Excess Cash.

(a) The Administrator shall establish one or more Exercise
Dates for each Offering Period. For the initial Offering Period under this Plan,
there shall be four Exercise Dates, occurring on the last business days of each
December, April, and August in such Offering Period.

(b) Each Participant's Purchase Right shall be exercised
automatically on each Exercise Date during the Offering Period to purchase the
maximum number of full shares at the applicable price using the Participant's
accumulated payroll deductions.

<PAGE> 34

(c) The shares purchased upon exercise of a Purchase Right
shall be deemed to be transferred to the Participant on the Exercise Date. A
Participant will have no interest or voting right in shares covered by a
Purchase Right until the Purchase Right has been exercised.

(d) Any cash remaining in a Participant's payroll deduction
account after the purchase of shares on an Exercise Date shall be carried
forward in that account for application on the next Exercise Date; provided that
at the termination of an Offering Period, any such cash shall be promptly
refunded returned to the Participant.

9. Registration and Delivery of Share Certificates.

(a) Shares purchased by a Participant under this Plan will be
registered in the name of the Participant, or in the name of the Participant and
his or her spouse, or in the name of the Participant and joint tenant(s) (with
right of survivorship), as designated by the Participant.

(b) As soon as administratively feasible after each Exercise
Date, the Company shall deliver to the Participant a certificate representing
the shares purchased upon exercise of a Purchase Right. If approved by the
Administrator in its discretion, the Company may instead (i) deliver a
certificate (or equivalent) to a broker for crediting to the Participant's
account or (ii) make a notation in the Participant's favor of non-certificated
shares on the Company's stock records.

10. Withdrawal; Termination of Employment.

(a) A Participant may withdraw all, but not less than all, of
the payroll deductions credited to his account under this Plan at any time
before an Exercise Date by giving written notice to the Administrator in a form
the Administrator prescribes from time to time. The Participant's Purchase Right
will automatically terminate on the date of receipt of the notice, all payroll
deductions credited to the Participant's account will be refunded promptly
thereafter, and no further payroll deductions will be made during the Offering
Period.

(b) Upon termination of a Participant's Continuous Status as
an Employee for any reason, including retirement or death, the payroll
deductions credited to the Participant's account will be promptly refunded to
the Participant or, in the case of death, to the person or persons entitled
thereto under Section 14 of this Plan, and the Participant's Purchase Right will
automatically terminate.

(c) If a Participant fails to remain in Continuous Status as
an Employee for at least 20 hours per week during an Offering Period, the
Participant will be deemed to have withdrawn from this Plan, the payroll
deductions credited to the Participant's account will be promptly refunded, and
the Participant's Purchase Right shall terminate.

6
<PAGE> 35

(d) A Participant's withdrawal from an offering will not
affect the Participant's eligibility to participate in a succeeding offering or
in any similar plan that may be adopted by the Company.

11. Use of Funds; No Interest.

Amounts withheld from Participants' Compensation under this
Plan shall constitute general funds of the Company and may be used for any
corporate purpose, and the Company shall not be obligated to segregate such
payroll deductions. No interest shall accrue on the payroll deductions of a
Participant in this Plan.

12. Number of Shares Reserved.

(a) Three million shares of Common Stock are reserved for
issuance under this Plan, as follows:

(i) 1,000,000 shares may be issued at any time before
termination of this Plan; and

(ii) an additional share (up to a total of 2,000,000
additional shares) may be issued for each share of
Common Stock that the Company redeems, in
public-market or private purchases, and designates
for this purpose after the date of Board approval of
this Plan.

(b) If the total number of shares that would otherwise be
subject to Purchase Rights granted on an Offering Date exceeds the number of
shares then available under this Plan (after deduction of all shares for which
Purchase Rights have been exercised or are then outstanding), the Administrator
shall make a pro-rata allocation of the available shares in a manner that it
determines to be as uniform and equitable as practicable. In such event, the
Administrator shall give written notice of the reduction and allocation to each
Participant.

(c) The Administrator may, in its discretion, transfer shares
reserved for issuance under this Plan into a plan of similar terms, as approved
by the Board, providing for the purchase of shares of Common Stock by employees
of Subsidiaries designated by the Board that do not (or do not thereafter)
participate in this plan. Such plan may, without limitation, provide for
variances from the terms of this Plan to take into account special circumstances
(such as foreign legal restrictions) affecting the employees of such designated
Subsidiaries.

13. Administration.

This Plan shall be administered by the Administrator. The
administration, interpretation, and application of this Plan by the
Administrator shall be final, conclusive, and binding upon all persons. Neither
Members of the Board nor the Administrator shall be liable for any action or
determination taken or made in good faith with respect to the Plan, or any
shares

7
<PAGE> 36

purchased or issued or Purchase Right exercised thereunder. Members of
the Board and other persons who are Employees are permitted to participate in
this Plan.

14. Designation of Beneficiary.

(a) A Participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
Participant's account under this Plan in the event of the Participant's death.

(b) A designation of beneficiary may be changed by the
Participant at any time by written notice. In the event of the death of a
Participant, and in the absence of a beneficiary validly designated under this
Plan who is living at the time of the Participant's death, the Administrator
shall deliver such shares and/or cash to the executor or administrator of the
Participant's estate, or if no such executor or administrator has been appointed
(to the Administrator's knowledge), the Administrator, in its discretion, may
deliver such shares and/or cash to the spouse or to any one or more dependents
or relatives of the Participant or, if no spouse, dependent, or relative is
known to the Administrator, then to such other person as the Administrator may
designate.

15. Transferability.

Neither payroll deductions credited to a Participant's account
nor any rights with regard to the exercise of a Purchase Right or to receive
shares under this Plan may be assigned, transferred, pledged, or otherwise
disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge, or other disposition shall be without
effect, except that the Administrator may treat such act as an election to
withdraw funds in accordance with Section 10 hereof.

16. Reports.

Individual accounts will be maintained for each Participant in
this Plan. Statements of account will be given to participating Employees
promptly following each Exercise Date, which statements will set forth the
amounts of payroll deductions, the per share purchase price, the number of
shares purchased and the remaining cash balance, if any.

17. Adjustments upon Changes in Capitalization.

(a) Subject to any required action by the stockholders of the
Company, the number of shares of Common Stock covered by each Purchase Right
under this Plan that has not yet been exercised and the number of shares of
Common Stock that have been authorized for issuance under this Plan but have not
yet been placed under a Purchase Right (collectively, the "Reserves"), as well
as the price per share of Common Stock covered by each Purchase Right under this
Plan that has not yet been exercised, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse

8
<PAGE> 37

stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration." Such adjustment shall
be made by the Administrator, whose determination shall be final, binding, and
conclusive. Except as expressly provided herein, no issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to a Purchase
Right.

(b) In the event of the proposed dissolution or liquidation of
the Company, the then-current Offering Period will terminate immediately before
the consummation of such proposed action, unless otherwise provided by the Board
or the Administrator (if the Administrator is not the Board). In the event of a
proposed sale of all or substantially all of the assets of the Company, or the
merger of the Company with or into another corporation (if stockholders of the
Company own less than 50% of the total outstanding voting power in the surviving
entity or a parent of the surviving entity after the merger), each Purchase
Right under this Plan shall be assumed or an equivalent purchase right shall be
substituted by the successor corporation or a parent or subsidiary of the
successor corporation, unless the successor corporation does not agree to assume
the Purchase Right or to substitute an equivalent purchase right, in which case
the Administrator may, in lieu of such assumption or substitution, accelerate
the exercisability of Purchase Rights, and allow Purchase Rights to be
exercisable (if the Board approves) as to shares as to which the Purchase Right
would not otherwise be exercisable, on terms and for a period that the
Administrator determines in its discretion. To the extent that the Administrator
accelerates exercisability of Purchase Rights as described above, it shall
promptly so notify all Participants in writing.

(c) The Administrator may, in its discretion, also make
provision for adjusting the Reserves, as well as the price per share of Common
Stock covered by each outstanding Purchase Right, if the Company effects one or
more reorganizations, recapitalizations, rights offerings, or other increases or
reductions of shares of its outstanding Common Stock, or if the Company
consolidates with or merges into any other corporation.

18. Amendment or Termination.

(a) The Board may at any time terminate or amend in any manner
this Plan; except, however, that no amendment may be made without prior approval
of the stockholders of the Company (obtained in the manner described in
paragraph 20) if it would:

(i) Increase the number of shares that may be issued
under this Plan;

(ii) Change the designation of the employees (or class of
employees) eligible for participation in this Plan;
or

(iii) If the Company has a class of equity securities
registered under Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")
at the time of such amendment, materially increase
the benefits that may accrue to Participants under
this Plan.

If any amendment requiring stockholder approval under this paragraph 19 of this
Plan is made after the first registration of any class of equity securities by
the Company under Section 12 of the Exchange Act, such stockholder approval
shall be solicited as described in paragraph 20 of this Plan.

(b) The Board may elect to terminate any or all outstanding
Purchase Rights at any time, except to the extent that exercisability of such
Purchase Rights has been accelerated pursuant to Section 17(b) hereof. If this
Plan is terminated, the Board may also elect to terminate Purchase Rights upon
completion of the next purchase of shares on the next Exercise Date or to permit
Purchase Rights to expire in accordance with their terms (with participation to
continue through such expiration dates). If Purchase Rights are terminated
before expiration, any funds contributed to this Plan that have not been used to
purchase shares shall be refunded to Participants as soon as administratively
feasible.

19. Notices.

All notices or other communications by a Participant to the
Company or the Administrator under or in connection with this Plan shall be
deemed to have been duly given when received in the form specified by the
Administrator at the location, or by the person, designated by the Administrator
for the receipt thereof.

20. Stockholder Approval.

(a) This Plan shall be submitted to the stockholders of the
Company for their approval within 12 months after the date this Plan is adopted
by the Board.

(b) If and in the event that the Company registers any class
of equity securities pursuant to Section 12 of the Exchange Act, any required
approval of the stockholders of the Company obtained after such registration
shall be solicited substantially in accordance with Section 14(a) of the
Exchange Act and the rules and regulations promulgated thereunder.

(c) If any required approval by the stockholders of this Plan
itself or of any amendment thereto is solicited at any time otherwise than in
the manner described in Section 17(b) hereof, then the Company shall, at or
before the first annual meeting of stockholders held after the later of (i) the
first registration of any class of equity securities of the Company under
Section 12 of the Exchange Act or (ii) the granting of a Purchase Right
hereunder to an Officer and Director after such registration, do the following:

<PAGE> 39

(a) furnish in writing to the holders entitled to vote
for this Plan substantially the same information that
would be required (if proxies to be voted with
respect to approval or disapproval of this Plan or
amendment were then being solicited) by the rules and
regulations in effect under Section 14(a) of the
Exchange Act at the time such information is
furnished; and

(b) file with, or mail for filing to, the Securities and
Exchange Commission four copies of the written
information referred to in subsection (i) hereof not
later than the date on which such information is
first sent or given to stockholders.

21. Conditions upon Issuance of Shares.

(a) Shares shall not be issued with respect to a Purchase
Right unless the exercise of such Purchase Right and the issuance and delivery
of such shares pursuant thereto shall comply with all applicable provisions of
law, domestic or foreign, including, without limitation, the Securities Act of
1933, as amended, the Securities Exchange Act of 1934, as amended, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange
upon which the shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

(b) As a condition to the exercise of a Purchase Right, the
Company may require the person exercising such Purchase Right to represent and
warrant at the time of any such exercise that the shares are being purchased
only for investment and without any present intention to sell or distribute such
shares if, in the opinion of counsel for the Company, such a representation is
required by any of the aforementioned applicable provisions of law.

22. Term of Plan.

This Plan shall become effective upon the earlier to occur of
its adoption by the Board of Directors or its approval by the stockholders of
the Company as described in Section 20 hereof. It shall continue in effect for a
term of 20 years unless sooner terminated under Section 19 hereof.

23. Additional Restrictions of Rule 16b-3.

The terms and conditions of Purchase Rights granted hereunder
to, and the purchase of shares by, persons subject to Section 16 of the
Securities Exchange Act of 1934 shall comply with the applicable provisions of
Rule 16b-3 of such Act. This Plan shall be deemed to contain, and such Purchase
Rights shall contain, and the shares issued upon exercise thereof shall be
subject to, such additional conditions and restrictions as may be required by
Rule 16b-3 to qualify for the maximum exemption from Section 16 of the
Securities Exchange Act of 1934 with respect to Plan transactions.
