</FONT>


<P align="left"><FONT size="2"><B>To the Participants and<BR>
Plan Administrator of the<BR>
Savings Plus Plan,<BR>
Lam Research 401(k)</B>
</FONT>

<P align="left"><FONT size="2">We have audited the financial statements of the Savings Plus Plan, Lam Research
401(k) (the Plan) as of December&nbsp;31, 2002 and 2001, and for the
year ended December&nbsp;31, 2002, as listed in the accompanying table of contents. These financial
statements are the responsibility of the Plan&#146;s management. Our responsibility
is to express an opinion on these financial statements based on our audits.
</FONT>

<P align="left"><FONT size="2">We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by the Plan&#146;s management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.
</FONT>

<P align="left"><FONT size="2">In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December&nbsp;31, 2002 and 2001, and the changes in net assets available for
benefits for the year ended December&nbsp;31, 2002, in conformity with accounting
principles generally accepted in the United States of America.
</FONT>

<P align="left"><FONT size="2">Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule, as listed in
the accompanying table of contents, is presented for the purpose of additional
analysis and is not a required part of the basic financial statements but is
supplementary information required by the Department of Labor&#146;s Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The supplemental schedule is the responsibility of the
Plan&#146;s management. The supplemental schedule has been subjected to the
auditing procedures applied in the audits of the basic financial statements
and, in our opinion, is fairly stated in all material respects in relation to
the basic financial statements taken as a whole.

<P align="left"><FONT size="2"><B>NOTE 1 &#151; THE PLAN AND ITS SIGNIFICANT ACCOUNTING POLICIES</B>
</FONT>

<P align="left"><FONT size="2"><B><I>General &#151; </I></B>The following description of the Savings Plus Plan, Lam Research
401(k) (the Plan)
provides only general information. Participants should refer to the Plan
document for a more complete description of the Plan&#146;s provisions.
</FONT>

<P align="left"><FONT size="2">The Plan is a defined contribution plan that was established in 1985 by Lam
Research Corporation (the Company) to provide benefits to eligible employees,
as defined in the Plan document. The Plan is currently designed to be
qualified under the applicable
requirements of the Internal Revenue Code, as amended, and the provisions of
the Employee Retirement Income Security Act of 1974 (ERISA), as amended.
</FONT>

<P align="left"><FONT size="2">Effective January&nbsp;1, 2002, the Company amended and restated the Plan document
in its entirety to incorporate provisions from federal laws passed since 1994,
including those laws commonly known as GUST and the Economic Growth and Tax
Relief Reconciliation Act of 2001 (EGTRRA). The Administrative
Committee (the Committee) approved the addition of Company common stock as an investment option effective for 2002.
</FONT>

<P align="left"><FONT size="2"><B><I>Administration </I></B><B>- </B>The Company has appointed the Committee to manage the
operation and administration of the Plan. The Company has contracted with a
third-party administrator who processes and maintains the records of
participant data and has contracted with Security Trust Company (STC)&nbsp;to act as
the trustee and custodian in 2001. Prior to that time, the Company had
contracted with Northwestern Trust Company (Northwestern) to act as the trustee
and custodian. Substantially all expenses incurred for administering the Plan
are paid by the Plan, unless paid by the Company.
</FONT>

<P align="left"><FONT size="2"><B><I>Estimates &#151; </I></B>The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities, and changes therein, and disclosure of
contingent assets and liabilities. Actual results could differ from those
estimates.
</FONT>

<P align="left"><FONT size="2"><B><I>Basis of accounting </I></B><B>- </B>The financial statements of the Plan are prepared on the
accrual method of accounting in accordance with accounting principles generally
accepted in the United States of America.
</FONT>

<P align="center"><FONT size="2">&nbsp;</FONT>

<P><HR noshade><P>
<H5 align="left" style="page-break-before:always"><A HREF="#toc">Table of Contents</A></H5><P>
<P align="left"><FONT size="2"><B><I>Investments </I></B><B>- </B>Investments of the Plan are held by STC at December&nbsp;31, 2002 and
2001 and are invested based solely upon instructions received from
participants.
</FONT>

<P align="left"><FONT size="2">The Plan&#146;s investments are valued at fair value as of the last day of the Plan
year, as measured by quoted market prices. Participant loans are valued at
cost, which approximates fair value.
</FONT>

<P align="left"><FONT size="2"><B><I>Cash and cash equivalents &#151; </I></B>All highly liquid investments purchased with an
original maturity of three months or less (generally money market funds) are
considered to be cash equivalents. These investments are usually held for a
short period of time, pending long-term investment.
</FONT>

<P align="left"><FONT size="2"><B><I>Income taxes - </i></B>The Plan has been amended since
receiving its latest favorable determination letter dated February&nbsp;2, 1996. In
2003, the Company intends to submit the Plan, as restated, to the Internal
Revenue Service for a new determination letter, which is expected to be
received in due course. The Plan is operated in
accordance with, and is intended to qualify under, the applicable requirements
of the Internal Revenue Code and related state statutes, and the trust,
which forms a part of the Plan, is intended to be exempt from federal income
and state franchise taxes.
</FONT>

<P align="left"><FONT size="2"><B><I>Reconciliation of financial statements to Form&nbsp;5500 &#151; </I></B>The differences between
the information reported in the financial statements and the information
reported in the Form&nbsp;5500 arise primarily from presenting the financial
statements on the accrual basis of accounting.
</FONT>

<P align="left"><FONT size="2"><B><I>Risks and uncertainties </I></B>- The Plan provides for various investment options in
any combination of investment securities offered by the Plan. In addition,
Company common stock is included in the Plan. Investment securities are
exposed to various risks, such as interest rate, market fluctuations and credit
risks. Due to the risk associated with certain investment securities, it is at
least reasonably possible that changes in market values, interest rates or
other factors in the near term would materially affect participants&#146; account
balances and the amounts reported in the statements of net assets available for
benefits and the statement of changes in net assets available for benefits.

<P align="left"><FONT size="2">Beginning in 2002, participants may elect to invest a portion of
their accounts in the common stock of the Company. The aggregate investment in
Company common stock at December&nbsp;31, 2002 was as follows:

<P align="left"><FONT size="2"><B>NOTE 3 &#151; PARTICIPATION AND BENEFITS</B>
</FONT>

<P align="left"><FONT size="2"><B><I>Participant contributions &#151; </I></B>Participants could elect to have the Company
contribute from 2% to 20% in 2002, and from 2% to 15% in 2001, of their
eligible pre-tax compensation per payroll period not to exceed the amount allowable under current
income tax regulations. Participants who elect to have the Company contribute
a portion of their eligible compensation to the Plan agree to accept an
equivalent reduction in taxable compensation. Contributions withheld are
invested in accordance with the participant&#146;s direction.
</FONT>

<P align="left"><FONT size="2">Participants are also allowed to make rollover contributions of amounts
received from other tax-qualified employer-sponsored retirement plans. Such
contributions are deposited in the appropriate investment funds in accordance
with the participant&#146;s direction and the Plan&#146;s provisions.
</FONT>

<P align="left"><FONT size="2"><B><I>Employer contributions &#151; </I></B>The Company is allowed to make matching contributions
as defined in the Plan and as approved by the Board of Directors. In 2002, the
Company matched 50% of each eligible participant&#146;s contribution up to a maximum
of the first 6% of the participant&#146;s eligible compensation on a per payroll
period basis. The Plan also allows for a discretionary profit sharing
contribution. No discretionary contribution has been made for the year ended
December&nbsp;31, 2002.
</FONT>

<P align="left"><FONT size="2"><B><I>Vesting &#151; </I></B>Participants are immediately vested in their entire account,
including employer matching and discretionary profit sharing contributions.
</FONT>

<P align="left"><FONT size="2"><B><I>Participant accounts &#151; </I></B>Each participant&#146;s account is credited with the
participant&#146;s contribution, Plan earnings or losses and an allocation of the
Company&#146;s contribution, if any. Allocation of the Company&#146;s contribution is
based on participant contributions or compensation, as defined in the Plan.
</FONT>

<P align="left"><FONT size="2"><B><I>Payment of benefits &#151; </I></B>Upon termination, each participant (or beneficiary) will
receive his or her total benefits in a lump sum amount equal to the value of
the participant&#146;s account, in installments over a period of years or over a
term certain under a non-transferable annuity contract. The Plan allows for
automatic lump sum distribution of participant account balances that do not
exceed $5,000.
</FONT>

<P align="left"><FONT size="2"><B><I>Loans to participants &#151; </I></B>The Plan allows participants to borrow not less than
$1,000 and up to the lesser of $50,000 or 50% of their account balance. The
loans are secured by the participant&#146;s balance reduced by
certain balances of outstanding or defaulted loans. Such loans bear interest at
the available market financing rates and must be repaid to the Plan within a
five-year period, unless the loan is used for the purchase of a principal
residence in which case the maximum repayment period is 15&nbsp;years. The specific
terms and conditions of such loans are established by the Committee.
Outstanding loans at December&nbsp;31, 2002 carry interest rates ranging from 5.25%
to 10.5%.
