                                     PART I

ITEM 1.  BUSINESS
THE COMPANY

    Lam   Research  Corporation  designs,  manufactures,  markets  and  services
semiconductor  processing  equipment  used  in  the  fabrication  of  integrated
circuits.  Lam is recognized by its customers worldwide as a leading supplier of
semiconductor production equipment. The Company's  products are used to  deposit
special films on a silicon wafer (deposition) and selectively etch away portions
of  various films  (etch) to create  an integrated circuit.  Deposition and etch
processes, which are repeated numerous  times during the fabrication cycle,  are
required to manufacture every semiconductor device produced today.

    The  Company currently sells a broad range  of plasma (dry) etch products to
address specific  applications,  including the  AutoEtch-Registered  Trademark-,
Rainbow-TM-,  and TCP-TM- (Transformer Coupled Plasma-TM-) product lines. In the
deposition market, Lam offers  its Epic-TM- high  density plasma (HDP)  chemical
vapor  deposition (CVD)  system, which addresses  advanced intermetal dielectric
applications, and  its Integrity-Registered  Trademark-  low pressure  (LP)  CVD
system,   a  fully  automated   batch  CVD  system   for  interlevel  dielectric
applications.

PRODUCTS

    Semiconductor wafers are subjected to a complex series of process steps that
result in the simultaneous creation  of many individual semiconductor  circuits.
The  basic  steps include  deposition,  photolithography, etching,  assembly and
testing. Lam's products are used in the deposition and etching process steps  of
semiconductor  device manufacturing and are  available as stand-alone systems or
on the  Company's  multichamber  Alliance-TM-  platform.  Lam  incorporates  its
interactive  control  system  software,  Envision-TM-,  for  advanced production
management on each of its systems.

    ETCH PRODUCTS

    The etch process defines line-widths  and other feature sizes on  integrated
circuits. Plasma etching, a dry etch technique, was developed to meet the demand
for  device  geometries  with  line-widths smaller  than  three  microns. Plasma
etching uses ionized gases  that chemically react  with unprotected portions  of
the  wafer to produce finely etched features that form the lines and patterns of
the integrated circuit.

    Today manufacturers  of advanced  integrated circuits  require etch  systems
that  can produce line-widths  as small as 0.25  micron (approximately 1/300 the
thickness of a human  hair) and in  the future are  expected to require  systems
capable  of producing  devices with feature  sizes smaller than  0.10 micron. In
addition, advanced manufacturing facilities are producing integrated circuits on
wafers of 150 or  200 mm (6 or  8 inches) in diameter,  and wafer diameters  are
expected  to  increase to  300  mm (12  inches)  by 1998.  To  accommodate these
decreasing   line-widths   and   increasing   wafer   diameters,   manufacturers
increasingly require more precise control over the etching process.

                                       1
<PAGE>
    Lam's  family of etch  systems incorporates plasma  technologies designed to
meet both current and future device requirements. In the fiscal years ended June
30, 1995,  1994  and 1993,  sales  of  the Company's  etch  systems  contributed
approximately 77%, 78% and 78% of the Company's total revenues, respectively.

    AUTOETCH.   The  AutoEtch family  was Lam's  initial product  line, with the
first AutoEtch product sold in January 1982. The AutoEtch product line  includes
the  490, 590 and  690 series for  etching polysilicon, oxide  and aluminum film
applications, respectively. Although the AutoEtch  series is more than  fourteen
years  old,  continued improvements  in  both reliability  and  performance have
enabled Lam to continue to offer it as a suitable product for film  applications
involving  line-widths of 0.8 micron or greater and wafer sizes of six inches or
smaller. In addition, Lam offers the service of refurbishing or  remanufacturing
AutoEtch systems.

    RAINBOW.   The first Rainbow etch system was introduced in 1987. The Rainbow
series of products addresses processes that utilize wafer sizes up to 200mm  and
feature  sizes as small  as 0.35 micron.  The Rainbow product  line includes the
Rainbow 4400,  4500,  4600  and  4700 series  for  etching  polysilicon,  oxide,
aluminum  and  tungsten  films,  respectively.  These  systems  are  designed to
accommodate evolving customer needs through hardware and process enhancements.

    The Rainbow product  series incorporates  a number of  unique features  that
offer  semiconductor  manufacturers  improved etch  capability,  reliability and
performance.  These  features  include  a  patented  wafer  handling  system,  a
proprietary  source for generating stable plasma,  and an overall product design
for which Lam has  received industry awards for  quality and reliability.  These
and   other  features  of  the  Rainbow  product  are  designed  to  enable  the
semiconductor manufacturer to  reduce wafer  particle contamination  to a  level
that  exceeds industry standards, and to improve etch selectivity and uniformity
while maintaining profile control and process flexibility.

    TCP.  Lam's TCP  product line of high  density, low pressure systems,  which
was  introduced in  late 1992,  incorporates the  Company's patented Transformer
Coupled Plasma-TM-  source  technology  for  etching  0.35  micron  and  smaller
geometries.  The Company  currently offers  the TCP  9600 series  for metal etch
applications  and  the  TCP  9400  series  for  polysilicon  and  polycide  etch
applications.  These  systems are  currently used  to produce  a broad  range of
advanced logic and memory devices and the Company believes these products  offer
technological capability to enable manufacturers to produce the next generations
of  advanced devices.  The TCP series  operates at lower  pressures for improved
pattern transfer control and  higher plasma density for  higher etch rates  with
independent  power control to  the lower electrode,  which improves etch results
across a wider process window. The TCP  system is designed to offer customers  a
reliable, lower cost of ownership solution to their advanced needs.

    OXIDE 9500.  The Oxide 9500 is a next-generation oxide etch system developed
to  address 0.35 micron and smaller geometries. This product, which incorporates
the Company's technology with certain technology obtained in connection with the
Drytek acquisition (See Note O to the Consolidated Financial Statements included
in Item 8) onto  the standard Rainbow platform,  is designed to offer  customers
high  reliability and  lower cost  of ownership.  The Company  began selling the
Oxide 9500 system in fiscal 1995.

    DEPOSITION PRODUCTS

    Chemical vapor deposition (CVD) involves the  deposition of thin films on  a
silicon wafer by exposing the wafer to various gases containing the materials to
be  deposited.  Films are  deposited to  form  both interconnect  and dielectric
layers of  an integrated  circuit.  The metal  interconnect layer  is  typically
deposited  on the  wafer surface by  a sputtering process  to provide electrical
connection between the  various circuit  elements, and the  dielectric layer  is
deposited  on  top  of  the  interconnect layer  by  CVD  to  provide electrical
insulation between the interconnect  layers. To increase circuit  functionality,
manufacturers  have designed circuits  with multilayer interconnections (stacked
levels  of  wiring  separated  by  insulating  dielectric  layers)  using  lower
resistivity materials for improved

                                       2
<PAGE>
device  performance. Multiple levels of  interconnect allow the circuit elements
to be moved closer  together, further increasing the  density of the  integrated
circuit.  Current state-of-the-art  devices may have  as many as,  or more than,
five interconnect and dielectric layers on the integrated circuit. Lam currently
manufactures two  dielectric  layer  deposition  products,  Epic  and  Integrity
systems, to address advanced multilevel films.

    EPIC.   Lam introduced its Epic high density plasma (HDP) CVD system in July
1993. The Epic system incorporates electron cyclotron resonance (ECR) technology
to form a  high-density, low-pressure plasma.  Its ability to  deposit and  etch
simultaneously an intermetal dielectric film enables it to fill gaps as small as
0.35  micron and  below and to  generate a  film that is  easily planarized. The
resulting film exhibits superior electrical qualities and significantly  reduces
the  need  for additional  chemical mechanical  polishing. The  Epic technology,
available on Lam's  Alliance platform,  has been installed  at several  customer
sites   and  is  currently  being  used   for  production  of  certain  advanced
microprocessors and in device development programs.

    INTEGRITY.   Integrity is  a low  pressure (LP)  CVD system  for  depositing
advanced interlevel dielectric films. This system utilizes a patented integrated
process  design for flowing gases rapidly over the wafer, forming films that are
highly uniform and planar to provide improved electrical performance.  Integrity
has  been installed at  several customer sites  and is currently  being used for
production of semiconductor devices and in device development programs.

RESEARCH AND DEVELOPMENT

    The market for  semiconductor capital  equipment is  characterized by  rapid
technological change. The Company believes that continued and timely development
of  new products and enhancements  to existing products are  necessary for it to
maintain  its  competitive   position.  Accordingly,  the   Company  devotes   a
significant  portion of  its personnel and  financial resources  to research and
development (R&D) programs and  seeks to maintain  close relationships with  its
customers to be responsive to their product needs.

    The  Company's  net R&D  expenses during  fiscal 1995,  1994 and  1993, were
approximately $127.8 million, $76.3 million and $43.9 million, respectively, and
represented 15.8%,  15.5% and  16.6% of  total revenue,  respectively. Such  R&D
expenses were net of third party funding, from SEMATECH, an industry consortium,
the  United  States  Display  Consortium  (USDC),  and  customers,  representing
approximately $2.6 million, $1.8  million and $1.6  million during fiscal  1995,
1994  and 1993, respectively. Such expenditures were used for the development of
new products and film  applications, and the  continued enhancement of  existing
products.  Current  projects  include  the  development  of  advanced  etch  and
deposition products.

    In June 1994, the Company received a two year contract from the USDC for the
development of  an etch  system, based  on the  Company's TCP  technology.  This
system  will be designed  for use in  the manufacture of  large scale flat panel
displays, for several  new technologies including  active matrix liquid  crystal
displays  (AMLCDs)  and Field  Emission Displays  (FEDs).  Included in  the $2.6
million of third  party funded R&D  for fiscal  1995 was $1.2  million from  the
USDC.

    The  Company expects to continue to invest  heavily in R&D. The Company also
must manage product transitions successfully,  as introductions of new  products
could  adversely affect  sales of existing  products. There can  be no assurance
that future technologies, processes or product developments will not render  the
Company's product offerings obsolete or that the Company will be able to develop
and  introduce  new  products  or  enhancements  to  its  existing  products and
processes in a  timely manner  which satisfy  customer needs  or achieve  market
acceptance.  The failure to do so could adversely affect the Company's business.
Furthermore, if the  Company is not  successful in the  development of  advanced
process equipment for manufacturers with whom it has formed strategic alliances,
its  ability  to sell  its products  to those  manufacturers would  be adversely
affected. In addition, in connection with  the development of the Company's  new
products, the Company invests in

                                       3
<PAGE>
high levels of pre-production inventory, and the failure to complete development
and  commercialization of these new products in  a timely manner could result in
inventory obsolescence, which could reduce the Company's financial results.

MARKETING, SALES AND SERVICE

    The Company's marketing and sales efforts are focused on building  long-term
relationships  with  its customers.  These efforts  are supported  by a  team of
product marketing managers,  sales personnel  and process  engineers that  works
closely with individual customers to find solutions to their process challenges.
After-sales  support is also an essential element of the Company's marketing and
sales program. The Company  maintains an ongoing  support relationship with  its
customers  and  has an  extensive network  of field  service personnel  in place
across the  United States,  Europe, Japan  and Asia  Pacific. In  addition,  the
Company  maintains an in-house group of highly skilled applications engineers to
respond to customer  process needs worldwide  when a higher  level of  technical
expertise  is required. The Company believes that its extensive support programs
and close  working  relationships  with  its customers  give  it  a  competitive
advantage.  The Company  also believes that,  by assisting its  customers in the
development of their  advanced manufacturing processes,  the customers are  less
likely to change equipment vendors.

    The  Company has 30 sales and  support centers located throughout the United
States, Europe, Japan, and Asia Pacific through which direct sales personnel and
independent sales representatives sell and  service the Company's products.  The
Company  expanded its sales and  support offices in Japan  to support the direct
sales efforts there which began in October 1994. More recently, the Company  has
increased  that effort by furthering its  direct sales and service capability in
Japan to directly market and support its advanced etch products. The Company now
offers its customers a comprehensive, two-year warranty package on all  released
products with 24 hour, seven days a week service.

    In  Japan,  the  Company  has  licensing  arrangements  with  Sumitomo Metal
Industries,  Ltd.  (Sumitomo)  and   Tokyo  Electron  Limited  (TEL).   Sumitomo
manufactures, sells and distributes certain of the Company's Rainbow products to
specific  customers in Japan.  TEL has a non-exclusive  license to sell products
incorporating certain features  of Lam's  proprietary etch  technology. In  June
1991,  the  Company  opened the  Lam  Technology  Center near  Tokyo,  Japan, to
establish a  presence  in Japan  and  to  assist Sumitomo  in  serving  Japanese
customers. In May 1993, Lam completed its advanced development and demonstration
laboratory  in  Sagamihara,  Japan,  which  allows  customers  to  evaluate  the
Company's recently  introduced  advanced  technology products.  The  Company  is
currently expanding in Japan by building a third floor on this existing building
and is in the design stage of a second facility in Sagamihara.

    Export  sales accounted for approximately  38%, 40% and 40%  of net sales in
fiscal 1995, 1994 and 1993, respectively. Export sales consist of sales from the
Company's U.S.  operating  subsidiary  to  nonaffiliated  customers  in  foreign
countries.  The Company anticipates  that export sales  will continue to account
for a significant portion of its net sales. Additionally, the Company  continues
to  expand  its  international  operations  including  expansion  of  its  Japan
operations and the opening of a manufacturing facility in Korea in July 1995. As
a result, a significant  portion of the Company's  sales and operations will  be
subject  to certain risks, including tariffs and other barriers, difficulties in
staffing and managing foreign subsidiary and branch operations, difficulties  in
managing  distributors, potentially adverse tax consequences and the possibility
of difficulty in accounts receivable collection. There can be no assurance  that
any  of these factors will  not have a material  adverse affect on the Company's
business, financial condition and results of operations.

CUSTOMERS

    The  Company's  customers   include  most  of   the  leading   semiconductor
manufacturers  worldwide. Revenue from  Intel accounted for 11%,  14% and 15% of
total revenue for the  years ended June 30,  1995, 1994 and 1993,  respectively.
Revenue from Motorola accounted for 10% of total revenue for the year ended June
30, 1994.

                                       4
<PAGE>
    The   Company's   business  depends   upon   the  capital   expenditures  of
semiconductor manufacturers, which in turn depend on the current and anticipated
market  demand  for  integrated  circuits  and  products  utilizing   integrated
circuits.  No assurance  can be given  that the Company's  revenue and operating
results will  not  be  adversely  affected if  downturns  in  the  semiconductor
industry occur.

BACKLOG

    The Company schedules production of its systems based upon order backlog and
customer  commitments. The Company includes in  backlog orders for which written
authorizations have been accepted and shipment  dates have been assigned. As  of
June  30, 1995, the Company's order backlog was approximately $252.6 million. As
of June 30, 1994, the Company's order backlog was approximately $145.9  million.
All  orders are  subject to cancellation  by the customer  with limited penalty.
Because of orders received  for systems to  be shipped in  the same quarter  and
possible customer changes in delivery schedules and cancellations of orders, the
Company's backlog at any particular date is not necessarily indicative of actual
sales for any succeeding period.

MANUFACTURING

    The  Company maintains facilities  at four locations  in Fremont, California
and one location in  Wilmington, Massachusetts for the  manufacture of its  etch
and  deposition products. The  Company completed, in  July 1995, a manufacturing
facility in CheonAn, Korea, outside of Seoul. The Company's Korean manufacturing
facility may experience difficulties in management, procurement, production  and
staffing. There can be no assurances that these factors will not have an adverse
affect on the Company's business, financial condition and results of operations.

    The  Company's manufacturing  activities consist  of assembling  and testing
components and subassemblies  that are  then integrated  into finished  systems.
Once  the manufacturing department has completed final testing of all electronic
and electromechanical subassemblies that make up one of the Company's  products,
the  completed  system is  process  tested. Stringent  cleanliness  controls are
present throughout  the  manufacturing,  process, and  testing  areas  of  these
facilities to reduce particle contamination. Much of the assembly and testing of
the  Company's products is  conducted in cleanroom  environments where personnel
are properly clothed to  reduce particulate contamination.  Prior to shipping  a
completed system, the customer's engineers may perform acceptance tests at Lam's
facility,  using the customer's  own wafers. After  passing the acceptance test,
the system  is  vacuum-bagged  in  a  cleanroom  environment  and  prepared  for
shipment.

    The  Company is subject to a  variety of governmental regulations related to
the discharge or disposal of  toxic, volatile, or otherwise hazardous  chemicals
used in the manufacturing process. The Company believes that it is in compliance
with  these regulations  and that  it has  obtained all  necessary environmental
permits to conduct its business, which permits generally relate to the  disposal
of  hazardous wastes. Nevertheless, the failure to comply with present or future
regulations could result in  fines being imposed on  the Company, suspension  of
production  or  cessation  of  operations. Such  regulations  could  require the
Company to acquire significant equipment or to incur substantial other  expenses
to  comply with environmental regulations. Any failure by the Company to control
the use  of, or  adequately  restrict the  discharge  or disposal  of  hazardous
substances could subject the Company to future liabilities.

EMPLOYEES

    As  of  September 1,  1995, the  Company  had approximately  3,600 full-time
employees. None of the  Company's employees is represented  by a union, and  the
Company has never experienced a work stoppage. Management considers its employee
relations  to be  satisfactory. In  addition, each  employee of  the Company has
signed agreements to maintain the  confidentiality of the Company's  proprietary
information, and most key employees have stock or stock option arrangements with
the Company that provide for the vesting of their interests over several years.

                                       5

COMPETITION

    The  semiconductor processing equipment industry  is highly competitive. The
Company faces substantial competition throughout the world. The Company believes
that, to remain competitive, it will require significant financial resources  to
offer  a  broad range  of  products, to  maintain  customer service  and support
centers worldwide, and  to invest  in product and  process R&D.  Certain of  the
Company's   existing  and  potential   competitors  have  substantially  greater
financial resources, more  extensive engineering,  manufacturing, marketing  and
customer  service and support  capabilities as well  as greater name recognition
than the Company. The Company expects its competitors to continue to improve the
design and performance of their current products and processes and to  introduce
new  products and processes with improved price and performance characteristics.
If the Company's  competitors enter  into strategic  relationships with  leading
semiconductor  manufacturers  covering etch  or  deposition products  similar to
those  sold  by  the  Company,  its  ability  to  sell  its  products  to  those
manufacturers  could be adversely  affected. No assurance can  be given that the
Company will continue to compete successfully in the United States or worldwide.

    Significant competitive factors  in the etch  equipment market include  etch
quality,  repeatability, process capability and flexibility, and overall cost of
ownership, including  reliability,  software  automation,  throughput,  customer
support  and  system  price.  Although the  Company  believes  that  it competes
favorably with  respect to  each  of these  factors,  the Company's  ability  to
compete  successfully in this  market will depend upon  its ability to introduce
product enhancements  and  new products  on  a timely  basis.  There can  be  no
assurance  that the Company will continue to compete successfully in the future.
In the  etch equipment  market, the  Company's primary  competitors are  Applied
Materials, Inc., TEL, and Hitachi Ltd.

    Significant  competitive factors in the  deposition equipment market include
film quality, flow  uniformity, contamination control,  temperature control  and
overall  cost of  ownership, including  throughput, system  reliability, cost of
consumables, system  price and  customer support.  In the  deposition  equipment
market,  the principal suppliers of equipment are Applied Materials, Inc., Canon
Sales Co. Inc., Novellus Systems, Inc. and Watkins-Johnson Company.

PATENTS AND LICENSES

    The Company has  a policy  of seeking  patents on  inventions governing  new
products  and processes developed  as part of  its ongoing research, engineering
and manufacturing  activities.  The  Company holds  United  States  patents  and
corresponding  foreign  patents covering  various aspects  of its  products. The
Company believes that  the duration of  its patents generally  exceeds the  life
cycles  of the technologies disclosed and  claimed therein. The Company believes
that although the patents it  holds and may obtain will  be of value, they  will
not  determine  the  Company's  success,  which  depends  principally  upon  its
engineering, marketing,  service  and  manufacturing  skills.  However,  in  the
absence  of patent protection, the Company  may be vulnerable to competitors who
attempt to  imitate  the  Company's  products  or  processes  and  manufacturing
techniques and processes. In addition, other companies and inventors may receive
patents  that contain claims applicable to the Company's products and processes.
The sale  of  the Company's  products  covered  by such  patents  could  require
licenses that may not be available on acceptable terms.

    From  time to time, the  Company is notified that it  may be in violation of
certain patents. In such cases, the Company's policy is to defend against claims
or negotiate licenses where considered appropriate. However, no assurance can be
given that  it  will  be  able to  obtain  necessary  licenses  on  commercially
reasonable terms. In October 1993, Varian Associates, Inc. (Varian) brought suit
against  the Company in  the United States District  Court, Northern District of
California,  seeking  monetary  damages  and  injunctive  relief  based  on  the
Company's  alleged infringement of certain patents  held by Varian. See "Item 3.
Legal Proceedings."

    In December 1986, the Company entered into a non-exclusive license agreement
with TEL licensing the  Company's AutoEtch technology  and chamber design.  This
license expired in December 1991, and, in January 1992, the Company entered into
a  new five year license agreement with TEL on substantially similar terms which
expires in December 1996.

    The Company has two license  agreements with Sumitomo. Under one  agreement,
Lam  granted  Sumitomo an  exclusive  license for  the  manufacture and  sale of
certain Rainbow etch systems in the Japanese market. Under the other  agreement,
Sumitomo  granted the Company an exclusive  license for the manufacture and sale
of Sumitomo's ECR CVD systems in North America and Europe.

ITEM 2.  PROPERTIES

    The Company's executive  offices and principal  manufacturing, and  research
and   development  facilities  are  located  in  twelve  buildings  in  Fremont,
California, occupying over 800,000 square  feet under leases expiring from  1995
to  2005. The Company is currently planning the expansion of its Fremont campus.
The Company also operates a  research and manufacturing facility in  Wilmington,
Massachusetts.

    In  addition,  the Company  leases office  space for  its service  and sales
personnel throughout  the United  States, Europe,  Japan and  Asia Pacific.  The
Company  completed, in  July 1995,  construction of  a manufacturing,  sales and
service facility  of 40,000  square  feet outside  of  Seoul, South  Korea.  The
Company  is currently expanding its facility in  Japan by building a third floor
on an existing  building, and is  in the design  stage of a  second facility  in
Sagamihara.

    The  Company's fiscal 1995 rental payments for the facilities occupied as of
June 30, 1995 aggregated approximately $9.5 million and are subject to  periodic
increases. The Company believes that its existing facilities are well maintained
and  in  good operating  condition. The  Company  continues to  consider leasing
additional facilities as necessary to support its expanding operations.

ITEM 3.  LEGAL PROCEEDINGS

    In October 1993, Varian Associates,  Inc. (Varian) brought suit against  the
Company  in the United  States District Court,  Northern District of California,
seeking monetary damages and  injunctive relief based  on the Company's  alleged
infringement  of certain  patents held  by Varian.  The lawsuit  is in  the late
stages of  discovery.  The  Company  has asserted  defenses  of  invalidity  and
unenforceability  of the patents that are the subject of the lawsuit, as well as
noninfringement of such patents by  the Company's products. While litigation  is
subject to inherent uncertainties and no assurance can be given that the Company
will  prevail in such litigation or will  obtain a license under such patents on
commercially reasonable  terms or  at all  if such  patents are  held valid  and
infringement  by the  Company's products, the  Company believes  that the Varian
lawsuit will not have  a material adverse effect  on the Company's  consolidated
financial statements.

    In  addition, the Company is  from time to time  notified by various parties
that it  may be  in violation  of  certain patents.  In such  cases, it  is  the
Company's   intention  to  seek  negotiated  licenses  where  it  is  considered
appropriate. The outcome  of these  matters will not,  in management's  opinion,
have  a  material  impact  on  the  Company's  consolidated  financial position,
operating results or cash flows.

Company and its Designated Subsidiaries with an opportunity to purchase
Common Stock of the Company through accumulated payroll deductions.  It is
the intention of the Company to have the Plan qualify as an "Employee Stock
Purchase Plan" under Section 423 of the Internal Revenue Code of 1986, as
amended.  The provisions of the Plan shall, accordingly, be construed so as

of any interruption or termination of service as an Employee. Continuous
Status as an Employee shall not be considered interrupted in the case of a
leave of absence agreed to in writing by the Company, provided that such

expiration of such leave is guaranteed by contract or statute.

         (h)  "DESIGNATED SUBSIDIARIES" shall mean the Subsidiaries which
have been designated by the Board from time to time in its sole discretion as
eligible to participate in the Plan.

which not less than 50% of the voting shares are held by the Company or a
Subsidiary, whether or not such corporation now exists or is hereafter
organized or acquired by the Company or a Subsidiary.

     3.   ELIGIBILITY.

         (a)  Any Employee who is an Employee as of the Offering Date of a
given offering period shall be eligible to participate in such Offering
Period under the Plan, subject to the requirements of paragraph 5(a) and the
limitations imposed by Section 423(b) of the Code.

         (b)  Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) if, immediately after
the grant, such Employee [or any other person whose stock would be attributed
to such Employee pursuant to Section 425(d) of the Code] would own stock
and/or hold outstanding options to purchase stock possessing five percent (5%)
or more of the total combined voting power or value of all classes of stock of
the Company or of any subsidiary of the Company, or (ii) which permits his
rights to purchase stock under all employee stock purchase plans of the
Company and its subsidiaries to accrue at a rate which exceeds Twenty-Five
Thousand Dollars ($25,000) of fair market value of such stock (determined at
the time such option is granted) for each calendar year in which such option
is outstanding at any time.

     4.  OFFERING PERIODS.  The Plan shall be implemented by one offering
during each offering period of the Plan, commencing on or about January 1,
1985, and continuing thereafter until terminated in accordance with paragraph
19 hereof.  Initially, the duration of each offering period shall be six
months. The Board or the Committee shall have the power to change the
duration of offering periods with respect to future offerings without
stockholder approval if such change is announced at least fifteen (15) days
prior to the scheduled beginning of the first offering period to be affected.

     5.  PARTICIPATION.

         (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deduction on the form
of Exhibit A to this Plan and filing it with the Company's payroll office
prior to the applicable Offering Date, unless a later time for filing the
subscription agreement is set by the Board or the Committee for all eligible
Employees with respect to a given offering.

         (b)  Payroll deductions for a participant shall commence on the
first payroll following the Offering Date and shall end on the Exercise Date
of the offering to which such authorization is applicable, unless sooner
terminated by the participant as provided in paragraph 10.

     6.  PAYROLL DEDUCTIONS.

         (a)  At the time a participant files his subscription agreement, he
shall elect to have payroll deductions made on each payday during the
offering period in an amount not exceeding five percent (10%) of the
Compensation which he receives on each payday during the offering period, and
the aggregate of such payroll deductions during the offering period shall not
exceed five percent (10%) of his aggregate Compensation during said offering
period.

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


                                       2
<PAGE>

         (c)  A participant may discontinue his participation in the Plan as
provided in paragraph 10, or may lower, but not increase, the rate of his
payroll deductions during the offering period by completing or filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate.  The change in rate shall be effective fifteen (15) days
following the Company's receipt of the new subscription agreement.

     7.  GRANT OF OPTION.

         (a)  On the Offering Date of each offering period, each eligible
Employee participating in the Plan shall be granted an option to purchase (at
the per share option price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
during such offering period by the lower of (i) eighty-five percent (85%) of
the fair market value of a share of the Company's Common Stock on the
Offering Date, or (ii) eighty-five percent (85%) of the fair market value of
a share of the Company's Common Stock on the Exercise Date; provided that in
no event shall an Employee be permitted to purchase during each offering
period more than a number of shares determined by dividing $12,500 by the
fair market value of a share of the Company's Common Stock on the Offering
Date, and provided further that such purchase shall be subject to the
limitations set forth in Section 3(b) and 12 hereof. Fair market value of a
share of the Company's Common Stock shall be determined as provided in
Section 7(b) herein.

         (b)  The option price per share of the shares offered in a given
offering period shall be the lower of:  (i) 85% of the fair market value of a
share of the Common Stock of the Company on the Offering Date; or (ii) 85% of
the fair market value of a share of the Common Stock of the Company on the
Exercise Date.  The fair market value of the Company's Common Stock on a
given date shall be determined by the Board or the Committee in its
discretion; provided, however, that where there is a public market for the
Common Stock, the fair market value per Share shall be the mean of the bid
and asked prices [or the closing price per share if the Common Stock is listed
on the National Association of Securities Dealers Automated Quotation
("NASDAQ") National Market System] of the Common Stock for such date, as
reported in the Wall Street Journal (or, if not so reported, as otherwise
reported by the NASDAQ System) or, in the event the Common Stock is listed on
a stock exchange, the fair market value per Share shall be the closing price
on such exchange on such date, as reported in the Wall Street Journal.

     8.  EXERCISE OF OPTION.  Unless a participant withdraws from the Plan as
provided in paragraph 10, his option for the purchase of shares will be
exercised automatically on the Exercise Date of the offering period, and the
maximum number of full shares subject to option will be purchased for him at
the applicable option price with the accumulated payroll deductions in his
account.  The shares purchased upon exercise of an option hereunder shall be
deemed to be transferred to the participant on the Exercise Date.  During his
lifetime, a participant's option to purchase shares hereunder is exercisable
only by him.

     9.  DELIVERY.  As promptly as practicable after the Exercise Date of
each offering, the Company shall arrange the delivery to each participant, as
appropriate, of a certificate representing the shares purchased upon exercise
of his option.  Any cash remaining to the credit of a participant's account
under the Plan after a purchase by him of shares at the termination of each
offering period, or which is insufficient to purchase a full share of Common
Stock of the Company, shall be returned to said participant.

     10.  WITHDRAWAL; TERMINATION OF EMPLOYMENT.

         (a)  A participant may withdraw all but not less than all the
payroll deductions credited to his account under the Plan at any time prior
to the Exercise Date of the offering period by giving written notice to the
Company in the form of Exhibit B to this Plan.  All of the participant's
payroll deductions credited to his account will be paid to him promptly after
receipt of his notice of withdrawal and his option for the current period
will be automatically terminated, and no further payroll deductions for the
purchase of shares will be made during the offering period.

         (b)  Upon termination of the participant's Continuous Status as an
Employee prior to the Exercise Date of the offering period for any reason,
including retirement or death, the payroll deductions credited to his account
will be returned to him or, in the case of his death, to the person or
persons entitled thereto under paragraph 14, and his option will be
automatically terminated.

         (c)  In the event an Employee fails to remain in  Continuous Status
as an Employee for at least twenty (20) hours per week during the offering
period in which the employee is a participant, he will be deemed to have
elected to withdraw from the Plan and the payroll deductions credited to his
account will be returned to him and his option terminated.

         (d)  A participant's withdrawal from an offering will not have any
effect upon his eligibility to participate in a succeeding offering or in any
similar plan which may hereafter be adopted by the Company.

     11.  INTEREST.  No interest shall accrue on the payroll deductions of a
participant in the Plan.

     12.  STOCK.

         (a)  The maximum number of shares of the Company's Common Stock
which shall be made available for sale under the Plan shall be 1,337,500
shares, subject to adjustment upon changes in capitalization of the Company
as provided in paragraph 18.  If the total number of shares which would
otherwise be subject to options granted pursuant to Section 7(a) hereof on
the Offering Date of an offering period exceeds the number of shares then
available under the Plan (after deduction of all shares for which options
have been exercised or are then outstanding), the Company shall make a pro
rata allocation of the shares remaining available for option grant in as
uniform a manner as shall be practicable and as it shall determine to be
equitable.  In such event, the Company shall give written notice of such
reduction of the number of shares subject to the option to each Employee
affected thereby and shall similarly reduce the rate of payroll deductions,
if necessary.

         (b)  The participant will have no interest or voting right in
shares covered by his option until such option has been exercised.

         (c)  Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant
and his spouse or, beginning with the offering period ending June 8, 1990, in
the name of the participant and any joint tenant(s) designated by the
participant.

     13.  ADMINISTRATION.  The Plan shall be administered by the Board of the
Company or a committee of one or more persons appointed by the Board.  The
administration, interpretation or application of the Plan by the Board or its
committee shall be final, conclusive and binding upon all participants.
Members of the Board and other persons who are eligible Employees are
permitted to participate in the Plan, provided that:

         (a)  No person who is eligible to participate in the Plan may vote
on any matter affecting the administration of the Plan or the grant of any
option pursuant to the Plan.


                                       4
<PAGE>

         (b)  If a Committee is established to administer the Plan, no
person who is eligible to participate in the Plan may be a member of the
Committee.

     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 the Plan in the event of such participant's death subsequent to the end
of the offering period but prior to the delivery to him of such shares and
cash.  In addition, a participant may file a written designation of a
beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to the Exercise Date
of the offering period.

         (b)  Such 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 the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the
estate of the participant, or if no such executor or administrator has been
appointed (to the knowledge of the Company), the Company, 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 Company, then to such other person as the Company
may designate.

     15.  TRANSFERABILITY.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option
or to receive shares under the 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 paragraph 14 hereof) by the participant.  Any
such attempt at assignment, transfer, pledge or other disposition shall be
without effect, except that the Company may treat such act as an election to
withdraw funds in accordance with paragraph 10.

     16.  USE OF FUNDS.  All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose,
and the Company shall not be obligated to segregate such payroll deductions.

     17.  REPORTS.  Individual accounts will be maintained for each
participant in the 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.

     18.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  Subject to any required
action by the stockholders of the Company, the number of shares of Common
Stock covered by each option under the Plan which has not yet been exercised
and the number of shares of Common Stock which have been authorized for
issuance under the Plan but have not yet been placed under option
(collectively, the "Reserves"), as well as the price per share of Common
Stock covered by each option under the Plan which 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 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 Board or the Committee, whose determination
in that respect 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 an option.


                                       5
<PAGE>

     In the event of the proposed dissolution or liquidation of the Company,
the offering period will terminate immediately prior to the consummation of
such proposed action, unless otherwise provided by the Board or the
Committee.  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, each option under the Plan shall be assumed or an equivalent
option shall be substituted by such successor corporation or a parent or
subsidiary of such successor corporation, unless such successor corporation
does not agree to assume the option or to substitute an equivalent option, in
which case the Board or the Committee shall, in lieu of such assumption or
substitution, provide for the participant to have the right to exercise the
option as to all of the optioned stock, including shares as to which the
option would not otherwise be exercisable.  If the Board or the Committee
makes an option fully exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Board or the Committee shall
notify the participant that the option shall be fully exercisable for a
period of thirty (30) days from the date of such notice, and the option will
terminate upon the expiration of such period.

     The Board or the Committee may, if it so determines in the exercise of
its sole discretion, also make provision for adjusting the Reserves, as well
as the price per share of Common Stock covered by each outstanding option, in
the event that the Company effects one or more reorganizations,
recapitalizations, rights offerings or other increases or reductions of
shares of its outstanding Common Stock, and in the event of the Company being
consolidated with or merged into any other corporation.

     19.  AMENDMENT OR TERMINATION.  The Board or the Committee may at any
time terminate or amend the Plan.  Except as provided in paragraph 18, no
such termination can affect options previously granted, nor may an amendment
make any change in any option theretofore granted which adversely affects the
rights of any participant, nor may an amendment be made without prior
approval of the stockholders of the Company (obtained in the manner described
in paragraph 21) if such amendment would:

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

         (b)  Permit payroll deductions at a rate in excess of ten percent
(10%) of the participant's Compensation;

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

         (d)  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 which
may accrue to participants under the Plan.

     If any amendment requiring stockholder approval under this paragraph 19
of the Plan is made subsequent to 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 21 of the
Plan.

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

     21.  STOCKHOLDER APPROVAL.

         (a)  Continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve months before or after the date the
Plan is adopted.

         (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 the 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 prior
to the first annual meeting of stockholders held subsequent to the later of
(1) the first registration of any class of equity securities of the Company
under Section 12 of the Exchange Act or (2) the granting of an Option
hereunder to an Officer and Director after such registration, do the
following:

                  (i)  furnish in writing to the holders entitled to vote
for the Plan substantially the same information which would be required (if
proxies to be voted with respect to approval or disapproval of the 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

                 (ii)  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.

     22.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued with
respect to an option unless the exercise of such option 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.

     As a condition to the exercise of an option, the Company may require
the person exercising such option 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.

     23.  TERM OF PLAN.  The 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 paragraph 21.  It shall continue
in effect for a term of twenty (20) years unless sooner terminated under
paragraph 19.

     24.  Additional Restrictions of Rule 16b-3.  The terms and conditions of
options 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 options 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.

4.    ADMINISTRATION OF THE PLAN.

      (a)    PROCEDURE.

             (i)     MULTIPLE ADMINISTRATIVE BODIES.  If permitted by Rule
16b-3, the Plan may be administered by different bodies with respect to Outside
Directors, Directors who are also Employees or Consultants, Officers who are not

             (ii)    ADMINISTRATION WITH RESPECT TO DIRECTORS AND OFFICERS
SUBJECT TO SECTION 16(b).  With respect to Option grants made to Employees who
are also Officers or Directors subject to Section 16(b) of the Exchange Act, the
Plan shall be administered by (A) the Board, if the Board may administer the
Plan in compliance with the rules governing a plan intended to qualify as a
discretionary plan under Rule 16b-3, or (B) a committee designated by the Board
to administer the Plan, which committee shall be constituted to comply with the
rules governing a plan intended to qualify as a discretionary plan under Rule
16b-3.  Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board.  From time to time the Board may
increase the size of the Committee and appoint additional members, remove
members (with or without cause) and substitute new members, fill vacancies
(however caused), and remove all members of the Committee and thereafter
directly administer the Plan, all to the extent permitted by the rules governing
a plan intended to qualify as a discretionary plan under Rule 16b-3.

             (iii)   ADMINISTRATION WITH RESPECT TO OTHER PERSONS. With respect
to Option grants made to Employees or Consultants who are neither Directors nor
Officers of the Company, the Plan shall be administered by (A) the Board or (B)
a committee designated by the Board, which committee shall be constituted to
satisfy Applicable Laws.  Once appointed, such Committee shall serve in its
designated capacity until otherwise directed by the Board.


                                       -4-
<PAGE>

The Board may increase the size of the Committee and appoint additional members,
remove members (with or without cause) and substitute new members, fill
vacancies (however caused), and remove all members of the Committee and
thereafter directly administer the Plan, all to the extent permitted by
Applicable Laws.

             (iv)    ADMINISTRATION WITH RESPECT TO AUTOMATIC GRANTS TO OUTSIDE
DIRECTORS. Automatic grants to Outside Directors shall be pursuant to a
non-discretionary formula as set forth in Section 5(b) hereof and therefore
shall not be subject to discretionary administration.

      (b)    POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

             (i)     to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(o) of the Plan;

             (ii)    to select the Consultants and Employees to whom Options may
be granted hereunder;

             (iii)   to determine whether and to what extent Options are granted
hereunder;

             (iv)    to determine the number of shares of Common Stock to be
covered by each Option granted hereunder;

             (v)     to approve forms of agreement for use under the Plan;

             (vi)    to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any award granted hereunder.  Such terms and
conditions may include, but are not limited to, the exercise price, the time or
times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding an Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

             (vii)   to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted;

             (viii)  to construe and interpret the terms of the Plan;

             (ix)    to prescribe, amend and rescind rules and regulations
relating to the Plan;


                                       -5-
<PAGE>

             (x)     to modify or amend each Option (subject to Section 15(c) of
the Plan);

             (xi)    to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option previously granted by
the Administrator;

             (xii)   to determine the terms and restrictions applicable to
Options; and

             (xiii)  to make all other determinations deemed necessary or
advisable for administering the Plan.

      (c)    EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's decisions,
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options.

5.  ELIGIBILITY.

      (a)      Options may be granted to Employees, Consultants and Outside
Directors provided that (i) Incentive Stock Options may only be granted to
Employees and (ii) Options may only be granted to Outside Directors in
accordance with the provisions of Section 5(b) hereof.  Each Option shall be
designated in the written option agreement as either an Incentive Stock Option
or a Nonstatutory Stock Option.  Subject to Section 5(b) with respect to Outside
Directors, an Employee, Consultant or Outside Director who has been granted an
option may, if such Employee, Consultant or Outside Director is otherwise
eligible, be granted additional Option(s).

      (b)    The provisions set forth in this Section 5(b) shall not be amended
more than once every six months, other than to comport with changes in the Code,
the Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder.  All grants of Options to Outside Directors under this Plan shall be
automatic and non-discretionary and shall be made strictly in accordance with
the following provisions:

             (i)     No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of shares to be
covered by Options granted to Outside Directors; provided, however, that nothing
in this Plan shall be construed to prevent an Outside Director from declining to
receive an Option under this Plan.

             (ii)    Each Outside Director shall be automatically granted an
Option to purchase 6,000 Shares on the first business day of January of each
calendar year.

             (iii)   The terms of an Option granted pursuant to this Section
5(b) shall be as follows:

<PAGE>

                     (A)   the term of the Option shall be ten (10) years;

                     (B)   except as provided in subsections 5(b)(iii)(G) and
(H) hereof, the Option shall be exercisable only while the Outside Director
remains a director;

                     (C)   the exercise price per share of Common Stock shall be
100% of the Fair Market Value on the date of grant of the Option;

                     (D)   the Option shall be 100% vested upon the date of
grant;

                     (E)   the consideration to be paid for the Shares to be
issued upon exercise of an automatic Outside Director Option shall consist of
cash or check;

                     (F)   if an Outside Director ceases to serve as a Director
the Option shall terminate immediately (except in the event of the Outside
Director's death or Disability, as described below);

                     (G)   in the event an Outside Director's Continuous Status
as an Outside Director terminates as a result of his or her Disability, he or
she may, but only within six (6) months from the date of termination, exercise
his or her Option. If he or she does not exercise such Option (which he or she
was entitled to exercise) within the time specified herein, the Option shall
terminate; and

                     (H)   in the event of the death of an Outside Director, the
Option may be exercised, at any time within six (6) months following the date of
death, by the Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance. If the option is not exercised
(to the extent it was entitled to be exercised) within the time specified
herein, the Option shall terminate.

6.    LIMITATIONS.

      (a)    Each Option shall be designated in the Notice of Grant as either an
Incentive Stock Option or a Nonstatutory Stock Option.  However, notwithstanding
such designations, to the extent that the aggregate Fair Market Value of the
Shares subject to an Optionee's incentive stock options granted by the Company,
any Parent or Subsidiary, which become exercisable for the first time during any
calendar year (under all plans of the Company or any Parent or Subsidiary)
exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock
Options.  For purposes of this Section 6(a), incentive stock options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time of grant.


                                       -7-
<PAGE>

      (b)    Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's employment or consulting
relationship with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

      (c)    No Employee shall be granted, in any fiscal year of the Company,
Options to purchase more than two hundred thousand (200,000) Shares.  The
foregoing limitation shall be adjusted proportionately in connection with any
change in the Company's capitalization as described in Section 12.

      (d)  If an Option is canceled in the same fiscal year of the Company in
which it was granted (other than in connection with a transaction described in
Section 12), the cancelled Option will be counted against the limit set forth in
Section 5(c).  For this purpose, if the exercise price of an Option is reduced,
the transaction will be treated as a cancellation of the Option and the grant of
a new Option.

7.    TERM OF PLAN. Subject to Section 18 of the Plan, the Plan shall become
effective upon the earlier to occur of its adoption by the Board or its approval
by the stockholders of the Company as described in Section 18 of the Plan.  It
shall continue in effect for a term of ten (10) years unless terminated earlier
under Section 14 of the Plan.

8.    TERM OF OPTION.  The term of each Option shall be stated in the Notice of
Grant; provided, however, that in the case of an Incentive Stock Option, the
term shall be ten (10) years from the date of grant or such shorter term as may
be provided in the Notice of Grant.  However, in the case of an Incentive Stock
Option granted to an Optionee who, at the time the Incentive Stock Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Incentive Stock Option shall be five (5) years from the date of grant or
such shorter term as may be provided in the Notice of Grant.

9.    OPTION EXERCISE PRICE AND CONSIDERATION.

      (a)    EXERCISE PRICE.  Except with respect to automatic stock option
grants to Outside Directors, the per share exercise price for the Shares to be
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

             (i)     In the case of an Incentive Stock Option:

                     (A)   granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.


                                       -8-
<PAGE>

                     (B)   granted to any Employee, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

             (ii)    In the case of a Nonstatutory Stock Option, the per Share
exercise price may be less than 100%, but shall be no less than 85%, of the Fair
Market Value per Share on the date of grant, if the Administrator determines
that a discount from the Fair Market Value is appropriate in lieu of the payment
of a reasonable amount of salary or cash bonus to the Optionee.

      (b)    WAITING PERIOD AND EXERCISE DATES. Except with respect to automatic
stock option grants to Outside Directors, at the time an Option is granted, the
Administrator shall fix the period within which the Option may be exercised and
shall determine any conditions which must be satisfied before the Option may be
exercised.  In so doing, the Administrator may specify that an Option may not be
exercised until the completion of a service period.

      (c)    FORM OF CONSIDERATION.  Except with respect to automatic stock
option grants to Outside Directors, the Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist of:

             (i)     cash;

             (ii)    check;

             (iii)   promissory note;

             (iv)    other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

             (v)     delivery of a properly executed exercise notice together
with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price;

             (vi)    any combination of the foregoing methods of payment; or

             (vii)   such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.


                                       -9-

10.   EXERCISE OF OPTION.

      (a)    PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.

      An Option may not be exercised for a fraction of a Share.

      An Option shall be deemed exercised when the Company receives:  (i)
written notice of exercise (in accordance with the Option Agreement) from the
person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised.  Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan.  Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, jointly with a person as specified by the Optionee.  Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the Optioned Stock, notwithstanding the
exercise of the Option.  The Company shall issue (or cause to be issued) such
stock certificate promptly after the Option is exercised.  No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 13 of the
Plan.

      Exercising an Option in any manner shall decrease the number of Shares
thereafter available, both for purposes of the Plan and for sale under the
Option, by the number of Shares as to which the Option is exercised.

      (b)    TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP.  In the event
that an Optionee's Continuous Status as an Employee or Consultant terminates
(other than upon the Optionee's death or Disability), the Optionee may exercise
his or her Option, but only within such period of time as is determined by the
Administrator, and only to the extent that the Optionee was entitled to exercise
it at the date of termination (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant).  In the case of an
Incentive Stock Option, the Administrator shall determine such period of time
(in no event to exceed three (3) months from the date of termination) when the
Option is granted.  In the case of a Nonstatutory Stock Option, such period of
time may not exceed six (6) months from the date of termination.  If, at the
date of termination, the Optionee is not entitled to exercise his or her entire
Option, the Shares covered by the unexercisable portion of the Option shall
revert to the Plan.  If, after termination, the Optionee does not exercise his
or her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.


                                      -10-
<PAGE>

             (i)     DISABILITY OF OPTIONEE.  In the event that an Optionee's
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within six (6) months from the date of such termination (or, if an Employee or
Consultant, such other period of time not exceeding twelve (12) months as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option), but only
to the extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant).  If, at the date of termination,
the Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

      (c)    DEATH OF OPTIONEE.  In the event of the death of an Optionee:

             (i)     during the term of the Option who is at the time of death
an Employee or Consultant and who shall have been in Continuous Status as an
Employee or Consultant since the date of grant of the Option, the Option may be
exercised, at any time within six (6) months (or such other period of time as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option) following
the date of death (but in no event later than the date of expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquired the right to exercise the Option by bequest or
inheritance, but only to the extent of the right to exercise that would have
accrued had the Optionee continued living and remained in Continuous Status as
an Employee or Consultant six (6) months after the date of death; or

             (ii)    within thirty (30) days (or such other period of time not
exceeding three (3) months as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the termination of Continuous Status as an Employee
or Consultant, the Option may be exercised, at any time within six (6) months
following the date of death (but in no event later than the date of expiration
of the term of such Option as set forth in the Notice of Grant), by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of termination.

11.   NON-TRANSFERABILITY OF OPTIONS.  An Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.


                                      -11-

12.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR ASSET
SALE.

      (a)    CHANGES IN CAPITALIZATION.  Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued 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 Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance 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 an Option.

      (b)    DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it will terminate immediately prior to the
consummation of such proposed action. The Board may, in the exercise of its sole
discretion in such instances, declare that any Option (except for Options
granted to Outside Directors) shall terminate as of a date fixed by the Board
and give each Optionee the right to exercise his or her Option as to all or any
part of the Optioned Stock, including Shares as to which the Option would not
otherwise be exercisable.

      (c)    MERGER OR ASSET SALE. In the event of 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 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 to substitute an equivalent option, the Board
shall, in lieu of such assumption or substitution, provide for the Optionee to
have the right to exercise the Option as to all or a portion of the Optioned
Stock, including Shares as to which it would not otherwise be exercisable.  If
the Administrator makes an Option fully exercisable in lieu of assumption or
substitution in the event of a merger or sale of assets, the Administrator shall
notify the Optionee that the Option shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option will terminate
upon the expiration of such period.  For the purposes of this paragraph, the
Option shall be considered assumed if, following the merger or sale of assets,
the option or right confers the right to purchase, for each Share of Optioned
Stock subject to the Option immediately prior to


                                      -12-
<PAGE>

the merger or sale of assets, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale of assets by holders of
Common Stock for each Share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger or sale of assets was
not solely common stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation and the
participant, provide for the consideration to be received upon the exercise of
the Option, for each Share of Optioned Stock subject to the Option, to be solely
common stock of the successor corporation or its Parent equal in Fair Market
Value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

13.   DATE OF GRANT.  The date of grant of an Option shall be, for all purposes,
the date on which the Administrator makes the determination granting such
Option, or such other later date as is determined by the Administrator.  Notice
of the determination shall be provided to each Optionee within a reasonable time
after the date of grant.

14.   AMENDMENT AND TERMINATION OF THE PLAN.

      (a)    AMENDMENT AND TERMINATION.  The Board may at any time amend, alter,
suspend or terminate the Plan.

      (b)    STOCKHOLDER APPROVAL. The Company shall obtain stockholder approval
of any Plan amendment to the extent necessary and desirable to comply with Rule
16b-3 or with Section 422 of the Code (or any successor rule or statute or other
applicable law, rule or regulation, including the requirements of any exchange
or quotation system on which the Common Stock is listed or quoted).  Such
stockholder approval, if required, shall be obtained in such a manner and to
such a degree as is required by the applicable law, rule or regulation.

      (c)    EFFECT OF AMENDMENT OR TERMINATION. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

15.   CONDITIONS UPON ISSUANCE OF SHARES.

      (a)    LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, Applicable Laws,
and the requirements of any stock exchange or quotation system upon which


                                      -13-
<PAGE>

the Shares may then be listed or quoted, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

      (b)    INVESTMENT REPRESENTATIONS.  As a condition to the exercise of an
Option, the Company may require the person exercising such Option 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.

16.   LIABILITY OF COMPANY.

      (a)    INABILITY TO OBTAIN AUTHORITY.  The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

      (b)    GRANTS EXCEEDING ALLOTTED SHARES.  If the Optioned Stock covered by
an Option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional stockholder approval, such Option shall
be void with respect to such excess Optioned Stock, unless stockholder approval
of an amendment sufficiently increasing the number of Shares subject to the Plan
is timely obtained in accordance with Section 15(b) of the Plan.

17.   RESERVATION OF SHARES.  The Company, during the term of this Plan, will at
all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

18.   STOCKHOLDER APPROVAL.  Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such stockholder approval shall be obtained
in the manner and to the degree required under applicable federal and state law.

provided in CLAUSE 8.2(ii)(A), if the Seller and the Buyer agree upon the
Scheduled Due Date for the Purchased Receivable prior to the payment of the

a day other than the Tentative Due Date, then the Purchaser and the Seller shall
make payments to each other as follows:

          (i)  PAYMENT DATE PRIOR TO TENTATIVE DUE DATE.  If the Purchased
               Receivable is paid prior to the Tentative Due Date, then the
               Purchaser shall pay to the Seller on the Payment Date, as an
               increase in the Purchase Price for the Purchased Receivable, the
               Discount Reduction Amount for the Purchased Receivable.  (In

               the Purchase Price for the Purchased Receivable, an amount equal
               to the interest which would have accrued on the Face Amount of
               the Purchased Receivable from the Tentative Due Date through the
               Payment Date at the Daily Rate in effect from time to time during
               such period.

Scheduled Due Date for the Purchased Receivable, then the Purchaser and the
Seller shall make payments to each other as follows:

          (i)  SCHEDULED DUE DATE PRIOR TO TENTATIVE DUE DATE.   If the
               Scheduled Due Date is prior to the Tentative Due Date and such

               and the Seller shall make payments to each other as follows:

               (A)  PAYMENT DATE PRIOR TO SCHEDULED DUE DATE.  If the Purchased
                    Receivable is paid prior to the Scheduled Due Date, then the
                    Seller shall pay to the Purchaser on the Payment Date (in

                    by the Seller to the Purchaser on the Scheduled Due Date
                    pursuant to CLAUSE 6.1), as a reduction of the Purchase

Purchased Receivable is outstanding until the Scheduled Due Date has been
determined for the Purchased Receivable and 60 days have passed after the
Scheduled Due Date, the Seller represents and warrants to the Purchaser as
follows with respect to the Receivable:

          (i)  The Receivable is an obligation of the Buyer to the Seller which
               arose from the sale by the Seller to the Buyer of Equipment in
               the ordinary course of the Seller's business.

               such Receivable in the Assignment.

        (iii)  The Receivable is not overdue.

         (iv)  The Receivable is a debt, the rights in which can be transferred
               by way of sale and assignment to the Purchaser pursuant to this
               Supplemental Agreement.

          (v)  The Receivable is legally and beneficially owned by the Seller
               or, after the sale to the Purchaser hereunder, by the Purchaser,
               free and clear of any liens, or other encumbrances exercisable
               against the Seller or the Purchaser.

               law or any agreement by which the Seller or any of its assets may
               be bound.  Without limiting the generality of the foregoing, the
               sale and assignment of the Receivable does not require the
               consent or approval of the Buyer or any other person.

          (x)  The Seller has, in all material respects, performed all of its
               obligations under and complied with all of the terms of the Sales
               Agreements relating to the Equipment, the sale of which gave rise
               to the Receivable (except for any obligations not required to be
               performed or any terms not required to be complied with prior to
               the effective date of any such representation and warranty).
               Shipment of the Equipment relating to the Receivable occurred on

               terms and conditions of the relevant Sales Agreement and (B) the

               the Purchased Receivable, whether or not the Scheduled Due Date

               pay a Repurchase Price equal to the sum of (A) the Purchase Price
               for the Purchased Receivable plus (B) the product of (1) the
               Discount Amount for the Purchased Receivable times (2) a fraction
               (expressed as a percentage rounded up to the nearest one
               thousandth of one percent), the numerator of which is the number
               of days in the period commencing on the Closing Date and ending
               on the Repurchase Date and the denominator of which is the number

               Rate in effect from time to time during such period.

        (iii)  If the Scheduled Due Date HAS been set PRIOR to the Repurchase
               Date and the Repurchase Date occurs AFTER the Tentative Due Date
               but BEFORE the Scheduled Due Date for the Purchased Receivable,
               then the Seller shall pay a Repurchase Price equal to the sum of
               (A) the Face Amount of the Purchased Receivable plus (B) the
               Funded Interest Accrued Amount.

         (iv)  If the Scheduled Due Date HAS been set PRIOR to the Repurchase
               Date and the Repurchase Date occurs AFTER the Tentative Due Date
               and AFTER the Scheduled Due Date for the Purchased Receivable,
               then the Seller shall pay a Repurchase Price equal to the sum of
               (A) the Face Amount of the Purchased Receivable, plus (B) the
               Funded Interest Amount for the Purchased Receivable plus (C) an
               amount equal to the interest which would have accrued on the Face
               Amount from the Scheduled Due Date through the Repurchase Date at
               the Daily Rate in effect from time to time during such period.

In addition to the Repurchase Price payable by the Seller to the Purchaser on

23.1      All payments to be made by or on behalf of the Seller or the
Collection Agent to the Purchaser under or pursuant to any of the provisions of
this Supplemental Agreement shall be made free and clear of and without
deduction for or on account of tax unless the Seller or the Collection Agent (as
the case may be) is required by any applicable law to make such payment subject
to the deduction or withholding of tax in which case the sum payable by the
Seller or the Collection Agent (as the case may be) in respect of which such
deduction or withholding is required to be made shall be increased to the extent
necessary to ensure that, after the making of such deduction or withholding
(including any additional deduction or withholding on such increased amount),
the Purchaser receives and retains (free from any liability in respect of any
such deduction or withholding) a net sum equal to the sum which it would have
received and so retained had no such deduction or withholding been made or
required to be made.

23.2      If the Seller or the Collection Agent makes any payment to the
Purchaser under or pursuant to this Supplemental Agreement in respect of which
it is required to make any such deduction or withholding, the Seller or the
Collection Agent (as the case may be) shall deliver to the Purchaser as soon as
practicable a certificate of deduction of tax and/or a receipt or other evidence
issued by the relevant taxation or other authority demonstrating the payment to
such authority of all amounts so required to be deducted or withheld.

23.3      If an event occurs which would result in the Seller or the Collection
Agent becoming obliged to make any payment pursuant to this CLAUSE 23, then each
of the parties hereto shall in good faith use reasonable endeavors to take such
reasonable steps as may be open to it to mitigate or avoid the effects of such
event, PROVIDED THAT nothing in this CLAUSE 23.3 shall:

          (i)  oblige any party hereto to incur any costs or expenses or to take
               or refrain from taking any action where in the reasonable opinion
               of such

                                       39

<PAGE>

               party to take or refrain from taking any action would be
               prejudicial to its interests; or

         (ii)  oblige any party hereto to disclose any confidential information
               relating to the organization of its affairs; or

        (iii)  interfere with the right of any party hereto to arrange its
               internal affairs in whatever manner it thinks fit.

24.  CONSEQUENCE OF A TERMINATION EVENT

24.1      Upon the occurrence of any Termination Event, other than the breach of

the Purchaser may, by notice to the Seller:

          (i)  terminate the obligation of the Purchaser to purchase any
               Receivable;

         (ii)  require the Seller to repurchase immediately the Purchased
               Receivable if the Scheduled Due Date has not been determined, in
               which event the provisions contained in CLAUSES 14.2 TO 14.4
               shall be applied MUTATIS MUTANDIS; and/or

        (iii)  exercise any and all other rights available to the Purchaser
               under this Supplemental Agreement or any of the other Transaction
               Documents or at law or in equity.

24.2      Upon the occurrence of any Insolvency Event in relation to the Seller,
automatically and without any notice to the Seller:

          (i)  the obligation of the Purchaser to purchase any Receivable shall
               terminate;

                                       40

<PAGE>

         (ii)  the Seller shall repurchase immediately the Purchased Receivable
               if the Scheduled Due Date has not been determined, in which event
               the provisions contained in CLAUSES 14.2 TO 14.4 shall be applied
               MUTATIS MUTANDIS; and/or

        (iii)  the Purchaser may exercise any and all other rights available to
               the Purchaser under this Supplemental Agreement or any of the
               other Transaction Documents or at law or in equity.

24.3      Upon the breach of CLAUSE 11.3, the Seller shall, upon the request of
the Purchaser, deliver to the Purchaser either (i) funds in an amount equal to
the Face Amount of the Purchased Receivable or (ii) a standby letter of credit
with a stated amount equal to the Face Amount of the Purchased Receivable.

          (i)  The Purchaser shall hold any funds delivered to it pursuant to
               clause (i) of the first sentence of this CLAUSE 24.3 in an
               interest bearing account in the name of the Seller as security
               for the performance by the Seller of its obligations under this
               Supplemental Agreement and the other Transaction Documents.  The
               Seller hereby grants to the Purchaser, as security for such
               obligations, a security interest in such funds and such account
               and agrees to perform such other actions as the Purchaser may
               request to establish, perfect, maintain and protect such security
               interest prior to the rights of others in such funds and such
               account.

         (ii)  Any standby letter of credit delivered to the Purchaser pursuant
               to clause (ii) of the first sentence of this CLAUSE 24.3 shall be
               in a form and substance and issued by a bank acceptable to the
               Purchaser.  The Purchaser shall have the right to draw under any
               such letter of credit for any amounts payable to the Purchaser
               hereunder which are not paid to the Purchaser when due.

                                       41

<PAGE>

Upon the payment or repurchase of the Purchased Receivable and the satisfaction
by the Seller of all its obligations under this Supplemental Agreement and the
other Transaction Documents, the Purchaser shall (A) deliver to the Seller the
funds, if any, remaining in any account established pursuant to clause (i) above
or (B) return to the Seller any letter of credit delivered to the Purchaser
pursuant to clause (ii) above, if any amounts remain available for drawing
thereunder.

25.  DEFAULT INTEREST AND INDEMNITY

25.1      If any sum due and payable by or on behalf of a party hereto (the
"Payer") to the other party (the "Payee") hereunder is not paid on the due date
therefor in accordance with the provisions hereof or if any sum due and payable
by the Payer under any judgment of any court in connection herewith is not paid
on the date of such judgment (the balance of such sum for the time being unpaid
being herein referred to as an "unpaid sum"), an unpaid sum shall bear interest
at the rate PER ANNUM which is equal to the Daily Rate plus two percent (2%),
such rate to change from time to time as the Daily Rate changes, for the period
beginning on, and including, such due date or, as the case may be, the date of
such judgment and ending on, but excluding, the date upon which the obligation
of the Payer to pay such sum is discharged (calculated on the basis of a year of
360 days).  Such default interest shall be payable upon demand of the Payee.

25.2      Each of the Seller and the Collection Agent undertakes to indemnify
the Purchaser against any loss or expense, including legal fees reasonably
incurred, which the Purchaser may sustain or incur as a consequence of any

performance of any of the obligations expressed to be assumed by it in this
Supplemental Agreement.

Transaction Documents or any amendment thereto or any waiver thereof.

26.2      The Seller or the Collection Agent will, upon demand, pay to the

under this Supplemental Agreement, the Assignment or any other Transaction
Document or any amendment thereto or any waiver thereof.

28.  REMEDIES AND WAIVERS

28.1      No failure to exercise, nor any delay in exercising, on the part of

thereof, nor shall any single or partial exercise of any right or remedy prevent
any further or other exercise thereof or the exercise of any other right or
remedy.

28.2      The rights and remedies herein provided are cumulative and not
exclusive of any rights or remedies provided by law.

29.  PARTIAL INVALIDITY

jurisdiction or with respect to such party or parties, it shall not, to the

N.V. ("PURCHASER").


                                    RECITALS

     A.   At the request of Guarantor, Purchaser, acting through its Tokyo
Branch, has entered into a Supplemental Receivables Purchase Agreement dated as
of June 28, 1995 (the "SUPPLEMENTAL PURCHASE AGREEMENT") with Purchaser and Lam
Research Co., Ltd., a Japanese corporation which is a wholly-owned subsidiary of
Guarantor ("SELLER"), pursuant to which (i) Purchaser has agreed to purchase
from Seller a certain account, promissory note or other obligation payable to
Seller (the "RECEIVABLE") upon the terms and subject to the conditions set forth
in the Supplemental Purchase Agreement and (ii) Seller has agreed to act as
collection agent for the Receivable so purchased by Purchaser from Seller (the
"PURCHASED RECEIVABLE").

     B.   Purchaser's obligation to purchase the Receivable from Seller under
the Supplemental Purchase Agreement is subject, among other conditions, to
receipt by Purchaser of this Guaranty, duly executed by Guarantor.


                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Guarantor hereby agrees with Purchaser as follows:

     1.   DEFINITIONS AND INTERPRETATION.

          (a)  DEFINITIONS.  Unless otherwise indicated in this Guaranty, each
     term set forth in SCHEDULE 1, when used in this Guaranty, shall have the
     respective meaning given to

                                       7-1

     SCHEDULE 1.

          (b)  OTHER INTERPRETIVE PROVISIONS.  Headings in this Guaranty are for
     convenience of reference only and are not part of the substance hereof.
     All terms defined in this Guaranty in the singular form shall have
     comparable meanings when used in the plural form and VICE VERSA.  This
     Guaranty shall be governed by and construed in accordance with the laws of
     the State of California without reference to conflicts of law rules.
     References in this Guaranty to any document, instrument or agreement
     (i) shall include all exhibits, schedules and other attachments thereto,
     (ii) shall include all documents, instruments or agreements issued or
     executed in replacement thereof and (iii) shall mean such document,
     instrument or agreement, or replacement or predecessor thereto, as amended,
     modified and supplemented from time to time and in effect at any given
     time.

     2.   CONTINUING GUARANTY.  Guarantor unconditionally guarantees and
promises to pay and perform as and when due, upon the demand of Purchaser, (a)
all obligations of the obligor under the Purchased Receivable ("BUYER") and (b)
all obligations of Seller under the Supplemental Purchase Agreement and all
other documents, instruments and agreements delivered to Purchaser in connection
therewith (collectively, including this Guaranty, the "TRANSACTION DOCUMENTS")

to be referred to herein collectively as the "GUARANTEED OBLIGATIONS").
Guarantor shall make all payments required hereunder to Purchaser, or its order,
at Purchaser's office located at the address set forth in SUBPARAGRAPH 8(A)
hereof, or at such other office as Purchaser may designate, on demand in such
lawful currency as is required by SUBPARAGRAPH 8(D) hereof.  Notwithstanding any
termination of this Guaranty in accordance with PARAGRAPH 6 hereof, this
Guaranty shall continue to be in full force and effect and applicable to any
Guaranteed Obligations arising thereafter which arise because prior payments of
Guaranteed Obligations are rescinded or otherwise required to be surrendered by
Purchaser after receipt.  The liability of Guarantor hereunder is independent of
the obligations of Seller and Buyer, and a separate action or actions may be
brought and prosecuted against Guarantor irrespective of whether action is
brought against

remedy of Guarantor against Seller, Buyer, any other guarantor with respect to
the Guaranteed Obligations or any security, whether resulting from an election
by Purchaser to foreclose upon security by nonjudicial sale, or otherwise;
(d) any setoff or counterclaim of Seller or any defense which results from any
disability or other defense of Seller or the cessation or stay of enforcement
from any cause whatsoever of the liability of Seller (including, without
limitation, the lack of

                                       7-7

<PAGE>

validity or enforceability of any Transaction Document); (e) any right to
exoneration of sureties which would otherwise be applicable; (f) until all
obligations of Purchaser under the Transaction Documents have been terminated
and the Guaranteed Obligations have been fully satisfied, any right of
subrogation or reimbursement and, if there are any other guarantors of the
Guaranteed Obligations, any right of contribution, and right to enforce any
remedy which Purchaser now has or may hereafter have against Seller, and any
benefit of, and any right to participate in, any security now or hereafter
received by Purchaser; (g) all presentments, demands for performance, notices of

guarantors of the Guaranteed Obligations and of other circumstances affecting
such nonpayment and nonperformance risks.  Without limiting the scope of any of
the foregoing waivers, Guarantor hereby waives (i) all rights and defenses
arising out of an election of remedies by Purchaser, even though that election
of remedies, such as a nonjudicial foreclosure with respect to security for a
Guaranteed Obligation, has destroyed Guarantor's rights of subrogation and
reimbursement against Seller by the operation of Section 580d of the Code of
Civil Procedure or otherwise, (ii) all rights and defenses Guarantor may have by
reason of protection afforded to Seller with respect to the Guaranteed
Obligations pursuant to the antideficiency or other laws of California limiting
or discharging the Guaranteed Obligations, including, without limitation,
Section 580a, 580b, 580d, or 726 of the California

                                       7-8

<PAGE>

Code of Civil Procedure, and (iii) all other rights and defenses available to
Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil
Code.

     7.   SUBORDINATION.  Guarantor hereby subordinates any obligations of
Seller to Guarantor (the "SUBORDINATED OBLIGATIONS") to the Guaranteed
Obligations as provided in this PARAGRAPH 7.  Until the occurrence of a
Potential Termination Event or Termination Event, Guarantor may receive
regularly scheduled payments from Seller on account of Subordinated Obligations.
Upon the occurrence and during the continuance of any Potential Termination
Event or Termination Event, however:

          (a)  Purchaser shall be entitled to receive payment of all Guaranteed
     Obligations before Guarantor receives payment of any Subordinated
     Obligations;

          (b)  Any payments on the Subordinated Obligations, if Purchaser so
     requests, shall be collected, enforced and received by Guarantor as trustee
     for Purchaser and be paid over to Purchaser on account of the Guaranteed
     Obligations, but without reducing or affecting in any manner the liability
     of Guarantor under the other provisions of this Guaranty; and

          (c)  Purchaser is authorized and empowered (but without any obligation
     to so do), in its discretion, (i) in the name of Guarantor, to collect and
     enforce, and to submit claims in respect of, the Subordinated Obligations
     and to apply any amounts received thereon to the Guaranteed Obligations and
     (ii) to require Guarantor (A) to collect and enforce, and to submit claims
     in respect of, the Subordinated Obligations and (B) to pay any amounts
     received on such Subordinated Obligations to Purchaser for application to
     the Guaranteed Obligations.

     Guarantor of any proceeds of any Receivable purchases, except to the extent
     such liability arises from the willful misconduct or gross negligence of
     the Indemnitees.  Upon receiving knowledge of any suit, claim or demand
     asserted by a third party that Purchaser believes is covered by this
     indemnity, Purchaser shall give Guarantor reasonable notice of the matter
     and an opportunity to defend it, at Guarantor's sole cost and expense, with
     legal counsel satisfactory to Purchaser.  Any failure or delay of Purchaser
     so to notify Guarantor of any such suit, claim or demand shall not relieve
     Guarantor of its obligations under this SUBPARAGRAPH 8(c) but shall reduce
     such obligations to the extent of any increase in those obligations caused
     solely by such failure or delay.  The obligations of Guarantor under this
     SUBPARAGRAPH 8(c) shall survive the payment and performance of the
     Guaranteed Obligations.

          (d)  CURRENCY OF PAYMENT.

               (i)  Guarantor shall make all payments of the Guaranteed
          Obligations hereunder in the currency in

                                      7-11

<PAGE>

          which such Guaranteed Obligations are required to be paid by Seller
          pursuant to the other Transaction Documents and shall make all other
          payments hereunder in the lawful currency of the United States.

              (ii)  If any sum due from Guarantor under this Guaranty or any
          order or judgment given or made in relation hereto has to be converted
          from the currency (the "first currency") in which the same is payable
          hereunder or under such order or judgment into another currency (the
          "second currency") for the purpose of (A) making or filing a claim or
          proof against Guarantor with any Governmental Authority, (B) obtaining
          an order or judgment in any court or other tribunal or (C) enforcing
          any order or judgment given or made in relation hereto, Guarantor
          shall, to the fullest extent permitted by law, indemnify and hold
          harmless each of the Persons to whom such sum is due from and against
          any loss suffered as a result of any discrepancy between (1) the rate
          of exchange used for such purpose to convert the sum in question from
          the first currency into the second currency and (2) the rate or rates
          of exchange at which such Person may, using reasonable efforts in the
          ordinary course of business, purchase the first currency with the
          second currency upon receipt of a sum paid to it in satisfaction, in
          whole or in part, of any such order, judgment, claim or proof.  The
          foregoing indemnity shall constitute a separate obligation of
          Guarantor distinct from its other obligations hereunder and shall
          survive the giving or making of any judgment or order in relation to
          all or any of such obligations.

          (e)  WAIVERS; AMENDMENTS.  Any term, covenant, agreement or condition
     of this Guaranty may be amended or waived if such amendment or waiver is in
     writing and is signed by Guarantor and Purchaser.  No failure or delay by
     Purchaser in exercising any right hereunder shall operate as a waiver
     thereof or of any other right nor shall any single or partial exercise of
     any such right preclude any other further exercise thereof or of any other
     right.  Unless otherwise specified in such waiver or consent, a waiver or
     consent given hereunder shall be effective only in the

                                      7-12

     specific instance and for the specific purpose for which given.

          (f)  ASSIGNMENTS.  This Guaranty shall be binding upon and inure to
     the benefit of Guarantor and Purchaser and their respective successors and
     permitted assigns, except that Guarantor may not assign or transfer any of
     its rights or obligations under this Guaranty without the prior written
     consent of Purchaser.  All references in this Guaranty to any Person shall
     be deemed to include all successors and assigns of such Person.

          (g)  CUMULATIVE RIGHTS, ETC.  The rights, powers and remedies of
     Purchaser under this Guaranty shall be in addition to all rights, powers
     and remedies given to Purchaser by virtue of any applicable law, rule or
     regulation of any Governmental Authority, the other Transaction Documents
     or any other agreement, all of which rights, powers, and remedies shall be
     cumulative and may be exercised successively or concurrently without
     impairing Purchaser's rights hereunder.

          (h)  PAYMENTS FREE OF TAXES, ETC.  All payments made by Guarantor
     under this Guaranty shall be made by Guarantor free and clear of and
     without deduction for any and all present and future taxes, levies,
     charges, deductions and withholdings.  In addition, Guarantor shall pay
     upon demand any stamp or other taxes, levies or charges of any jurisdiction
     with respect to the execution, delivery, registration, performance and
     enforcement of this Guaranty.  If any taxes, levies, charges or other
     amounts are required to be withheld from any amounts payable to Purchaser
     hereunder, the amounts so payable to Purchaser shall be increased to the
     extent necessary to yield to Purchaser (after payment of all such amounts)
     any such amounts payable hereunder in the amounts specified in this
     Guaranty.  Upon request by Purchaser, Guarantor shall furnish evidence
     satisfactory to Purchaser that all requisite authorizations and approvals
     by, and notices to and filings with, governmental authorities and
     regulatory bodies have been obtained and made and that all requisite taxes,
     levies and charges have been paid.

          (i)  PARTIAL INVALIDITY.  If at any time any provision of this
     Guaranty is or becomes illegal, invalid or unenforceable in any respect
     under the law or any jurisdiction, neither the legality, validity or
     enforceability of the remaining provisions of this Guaranty nor the
     legality, validity or enforceability of such provision under the law of any
     other jurisdiction shall in any way be affected or impaired thereby.

          (j)  JURY TRIAL.  EACH OF GUARANTOR AND PURCHASER, TO THE FULLEST
     EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT TO
     TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
     COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY.

          (k)  SUBMISSION TO JURISDICTION.  Guarantor hereby irrevocably and
     unconditionally:

               (i)  Submits for itself and its property in any legal action or
          proceeding relating to this Guaranty, or for recognition and
          enforcement of any judgment in respect thereof, to the non-exclusive
          jurisdiction of the courts of the State of California and the courts
          of the United States of America for the Northern District of
          California, and consents and agrees to suit being brought in such
          courts as Purchaser may elect;

              (ii)  Waives any objection that it may now or hereafter have to
          the venue of any such action or proceeding in any such court or that
          such proceeding was brought in an inconvenient court and agrees not to
          plead or claim the same; and

              (iii) Agrees that nothing herein shall affect Purchaser's right to
          effect service of process in any manner permitted by law, and that
          Purchaser shall have the right to bring any legal proceedings
          (including a proceeding for enforcement of a judgment entered by any
          of the aforementioned courts) against Guarantor in such courts or in
          any other court or jurisdiction in accordance with applicable law.

     IN WITNESS WHEREOF, Guarantor has caused this Guaranty to be executed as of
the day and year first above written.

day of the Purchase Period by giving to the Purchaser not less than three (3)
business days' notice of the date and amount of the cancellation.

2.2         The sale referred to in Parts 3 and 4 does not constitute and is not
intended to result in the creation or assumption by the Purchaser of any
obligation of the Seller or any other person in connection with the Receivables
or the Sales Agreements, or under any other agreement or instrument relating
thereto.

2.3         For purposes of this Agreement, if as of the relevant Closing Date a
Purchased Receivable is, in accordance with the Sales Agreement for the
Equipment in relation to such Purchased Receivable, to be payable by the
relevant Buyer in two or more installments, each amount owed by such Buyer
payable in each such installment shall be deemed and treated as if each such
amount were a separate and single Purchased Receivable.

10.1         In relation to each of the Purchased Receivables, an adjustment
amount (the "Adjustment Amount") (if any) calculated in accordance with Clause
10.3 shall be payable on a Receivables Payment Date for such Purchased
Receivable.  The Adjustment Amount shall be payable by the Seller to the
Purchaser if a Receivables Payment Date falls on a date which is later than the
Tentative Receivables Due Date for such Purchased Receivable.  The Adjustment
Amount shall be payable by the Purchaser to the Seller if a Receivables Payment
Date falls on a date which is earlier than a Tentative Receivables Due Date for
such Purchased Receivable.

10.2         In relation to a Purchased Receivable for which the Scheduled
Receivables Due Date has not been determined as of the date (the first "Reset
Date") three (3) business days before the Tentative Receivables Due Date, the
Seller shall on the first Reset Date notify in writing the Purchaser of (i) the
date (the first "Extended Tentative Date") on or around which the Seller
reasonably expects such Purchased Receivable will be paid by the relevant Buyer
and (ii) its election of either the Adjustment LIBOR Based Rate or the
Adjustment COF Based Rate as a rate applicable to the period up to the Extended
Tentative Date.  If the Scheduled Due Date has not been determined as of the

Tentative Date, the Seller shall on the second Reset Date notify in writing the
Purchaser of the second Extended Tentative Date and its election of the
applicable rate in a manner similar to the first Reset Date, which procedures,
if applicable, shall be repeatedly taken.  In relation to a Purchased Receivable
for which the Scheduled Receivables Due Date has been determined as of the Reset
Date or any subsequent Reset Date, the Seller shall on such Reset Date notify in
writing the Purchaser of its election of either the Adjustment LIBOR Based Rate
or the Adjustment COF Based Rate as a rate applicable to the period up to such
Scheduled Receivables Due Date.

10.3         "Adjustment Amount" in relation to a Purchased Receivable and a
Receivables Payment Date for such Purchased Receivable shall be the amount in

Paragraph (i) below, if it is payable by the Purchaser, or the amount equal to
the sum of each Partial Adjustment Amount to be calculated in accordance with
the formula set forth in Paragraph (ii) below, if it is payable by the Seller.

             (i)  A = B x C x (D/E)

             where:

                  A =  the Adjustment Amount
                  B =  the Paid Amount on such Receivables Payment Date
                  C =  the Discount Rate applicable to such Purchased Receivable
                  D =  the Adjustment Period applicable to such Purchased
Receivable and Receivables Payment Date
                  E =  the Discount Period applicable to such Purchased
Receivable; and


                                       18
<PAGE>

             (ii)   A = B x C x (D/365)

             where:

                    A =  each Partial Adjustment Amount
                    B =  the Paid Amount on such Receivables Payment Date
                    C =  (x) the Adjustment LIBOR Based Rate or the Adjustment
COF Based Rate, as elected by the Seller, applicable to the Reset Period
relating to the relevant Partial Adjustment Period or (y) the Adjustment LIBOR
Based Rate applicable to the Overdue Reset Period relating to the relevant
Partial Adjustment Period
                    D =  each Partial Adjustment Period applicable to such
Purchased Receivable and Receivables Payment Date

             Provided that the Margin applicable to the Adjustment LIBOR Based
Rate or the Adjustment COF Based Rate, as the case may be, shall be reduced to
nine-twentieths of one percent (0.45%) for the days elapsed during a Partial
Adjustment Period which also fall under the Margin Reduction Period in relation
to such Purchased Receivable.  The "Margin Reduction Period" in relation to a
Purchased Receivable shall be the period during which (x) the Acceptance or the
Partial Acceptance of the Equipment in relation to such Purchased Receivable has
occurred, (y) the conditions precedent set out in Paragraph 2(a) of Part 1 or
Part 2, as the case may be, of the Second Schedule have been satisfied, or, as
the case may be, the P/N in relation to such Purchased Receivable has been
issued by the relevant Buyer to the Purchaser and (z) the relevant Buyer is
given and maintains a rating in respect of its long-term unsecured and
unsubordinated debt being "A" or higher by any of Standard & Poor's Corporation,
Moody's Investors Service Inc. or Japan Bond Research Institute.

10.4         If, in relation to a Purchased Receivable, there is the Margin
Reduction Period prior to the Tentative Receivables Due Date, the Margin
Reduction Amount shall be payable by the Purchaser to the Seller on such
Tentative Receivables Due Date.  The "Margin Reduction Amount" in relation to a
Purchased Receivable shall be the amount in Yen which shall be calculated by
multiplying the Purchase Price of such Purchased Receivable (or, if a Receivable
Payment Date for such Purchased Receivable comes earlier than the Tentative
Receivables Due Date, such portion of such Purchase Price as is corresponding to
a Paid Amount on such Receivables Payment Date) (i) by nine-twentieths of one
percent (0.45%) and (ii) further by a fraction the numerator of which is the
actual number of days elapsed during such Margin Reduction Period up to, but
excluding, such Tentative Receivables Due Date (or, if a Receivables Payment
Date for such Purchased Receivable comes earlier than the Tentative Receivables
Due Date, such Receivables Payment Date) and the denominator of which is 365.

Collection Agent to the Purchaser under or pursuant to any of the provisions of
this Agreement shall be made free and clear of and without deduction for or on
account of tax unless the Seller or the Collection Agent (as the case may be) is

may, by notice to the Seller,  declare that the Termination has occurred, at
which time Termination shall be deemed to have occurred, provided, however, that

automatically, without notice by the Purchaser, as of the time immediately
preceding the institution of the relevant proceeding or the filing of the

             (i)   the Purchase Period shall be deemed to have expired; and

which (x) the conditions precedent set out in Paragraph 2(a) of Part 1 or Part
2, as the case may be, of the Second Schedule have been satisfied and the
Scheduled Receivables Due Date has been determined or (y) the condition
precedent set out in Paragraph 2(b) of Part 1 or Part 2, as the case may be, of
the Second Schedule has been satisfied and the relevant P/N has been assigned to
the Purchaser in accordance with this Agreement, shall be immediately


                                       35

repurchased by the Seller or its designee, in which event the provisions
contained in Clauses 17.2 to 17.4 shall be applied mutatis mutandis.


27.3         If the Termination Event shall have occurred as a result of the
Guarantor's breach of any of its obligations set out in sub-paragraphs (f), (g)
and (h) of paragraph 4 of the Guaranty, the Seller shall cause cash in the
amount equal to thirty percent (30%) of the total amount of the Face Value or
(if the Reduction Adjustment Amount has been paid) the Revised Face Value of all
of Purchased Receivables as described in Paragraph(ii) of Clause 27.2 shall be
provided to the Purchaser by way of security for the Seller's obligations
hereunder and the Guarantor's obligations under the Guaranty in relation to such
Purchased Receivables in a manner reasonably satisfactory to the Purchaser
within five (5) business days after the date on which the Termination Event
occurred and such cash by way of security shall be lawfully maintained.  If and
insofar as (i) the Seller's such obligation detailed in the first sentence of
this Clause 27.3 shall be complied with and (ii) no other Termination Event or
Potential Termination Event shall have been occurred, notwithstanding Paragraph
(ii) of Clause 27.2, such Purchased Receivables shall not be required to be
repurchased by the Seller.  The Purchaser shall hold any funds delivered to it
pursuant to the first sentence of this Clause 27.3 in an interest bearing

to any factual matters, including those contained in said certificate.

      For the purposes of rendering this opinion, we have assumed without
independently verifying:

(A)   the genuineness of all seal impressions and signatures on documents that
we have examined, and the authenticity and completeness of all documents
submitted to us as originals or copies of originals;

(B)   the exact conformity to complete original documents of all documents
submitted to us as copies;


                                       67
<PAGE>

(C)   the Purchaser is a corporation duly organized, validly existing and in
good standing under the laws of the kingdom of Netherlands, and the Tokyo branch
of the Purchaser has full and complete corporate power and authority to execute
and deliver, and to perform its obligations under the Agreement;

(D)   the execution and delivery of the Agreement by the Purchaser, and the
performance by the Purchaser of its obligations under the Agreement, have been
duly authorized by all necessary corporate action; and

(E)   the Agreement and all other documents submitted to us have been duly
executed and delivered by or on behalf of all persons and entities that are
signatories thereto (other than Lam).

      Based upon and subject to the foregoing, and further subject to the
qualifications hereinafter set forth, we are of the opinion that:

1.    Lam is a corporation validly existing under the laws of Japan with
corporate power to enter into the Agreement and each Assignment and to exercise
its rights and perform its obligations under the Agreement and each Assignment,
and all corporate action required to authorize its execution of the Agreement
and each Assignment and its performance of its obligations thereunder has been
duly taken.

2.    Lam has corporate power and all governmental license, authorizations,
consents and approvals necessary to carry on its business currently conducted in
Japan.

3.    There is no consent, approval, order or authorization of, or registration,
filing, recordation or enrollment with, or giving of prior notice to, any
Japanese governmental body or agency or any Japanese court required with respect
to the execution, delivery and performance of the Agreement by Lam.  The
execution, delivery and performance of the Agreement by Lam do not contravene
any provision of applicable laws of Japan or Lam's Articles of Incorporation or
other internal regulations.

4.    The claims of the Purchaser against Lam under the Agreement will rank at
least pari passu with the claims of all of Lam's other unsecured creditors.

5.    In any legal proceedings taken in Japan in relation to the Agreement or
any Assignment, Lam will not be entitled to claim for itself or any of its
assets sovereign immunity from suit, execution, attachment or other legal
process.

6.    The choice of Japanese law to govern the Agreement is a valid choice of
law, and the submission by Lam to the jurisdiction of the Tokyo District Court
is a valid submission to the jurisdiction of such court as a court of first
instance, except in cases where other courts in Japan have exclusive
jurisdiction.


                                       68
<PAGE>

7.    Save for Japanese stamp duties, no similar taxes are payable in respect of
the execution and delivery of the Agreement or any Assignment.

8.    The Agreement has been duly executed and delivered by Lam, and the
obligations expressed to be assumed by Lam in the Agreement are legal and valid
obligations binding on Lam and enforceable against Lam in accordance with their
respective terms.

      Our opinions set forth herein are subject to the following qualifications
and limitations:

(a)   we express no opinion as to:

      (i)    except as set forth in paragraph 7, compliance with or the effect
of any tax law; or

      (ii)   the availability of specific performance, injunctive relief, or any
other similar remedy;

(b)   the opinions expressed above are subject to limitation by statute of
limitation, appropriate court procedures and the full discretion of the court,
which must consider the public order and good morals doctrine and the abuse of
rights doctrine;

(c)   the legality, validity, binding nature and enforceability of the Agreement
may be limited by the application of:

      (i)    bankruptcy, insolvency, reorganization, fraudulent conveyance and
other similar laws affecting the rights, powers, privileges, remedies and/or
interests of creditors generally; or

      (ii)   the Interest Rate Restriction Law, Risoku Seigen Ho (the "Interest
Rate Law").  Under the Interest Rate Law, the maximum rate of interest per annum
recoverable by action in the courts of Japan is as set forth below:

             Principal Amount                Interest Rate (%)

             Less than _100,000                     20

             _100,000 or more but                   18
             less than 1,000,000

             _1,000,000 or more                     15


             The Interest Rate Law further provides that if any stipulated
default interest amount sought to be recoverable by action in the courts of
Japan exceeds double


                                       69
<PAGE>

the amount calculated in accordance with the interest rate set forth above, the
right of the party seeking recovery to recover an amount in excess of double the
amount as calculated above shall be unenforceable;

(d)   we express no opinion on any provision in the Agreement requiring written
amendments and waivers of the Agreement insofar as it suggests that oral or
other modifications, amendments or waivers could not be effectively agreed upon
or granted between or by the parties or by a duly authorized agent; and

(e)   the court may not give full effect to an indemnity for legal costs.

      We are members of the bar of Japan and, with your permission, our opinion
is limited to the laws of Japan.

      This opinion is given as of the date hereof and only for the benefit of
the addressees and on the basis that it will be relied upon only by such
addressees and will not be disclosed to any third party other than such
addressees' professional advisers.

                                   Very truly yours,

          Part 2:    Form of Opinion of Jan J. Kang


                                                        , 1995


ABN AMRO Bank

Minato-ku, Tokyo
(the "Purchaser")

Dear Sirs:

      I am senior counsel for Lam Research Corporation, a Delaware corporation
(the "Guarantor"), in connection with its preparation, execution and delivery of
the Guaranty (the "Guaranty") dated as of      , 1995 in relation to the
Receivables Purchase Agreement, dated as of      , 1995 (the "Agreement") among
the Purchaser and Lam Research Co., Ltd., a Japanese corporation, as Seller and
Collection Agent.  Capitalized terms used but not otherwise defined herein shall
have the respective meanings assigned to such terms in the Guaranty or the
Agreement.

      Based on my examination of such corporate records, certificates and other
documents and questions of law as I have considered necessary or appropriate, it
is my opinion that:

1.    The Guarantor is a corporation duly organized and is validly existing and
in good standing under the laws of the state of Delaware with power to enter
into the Guaranty and to exercise its rights and perform its obligations
thereunder and all corporate and other action required to authorize its
execution of the Guaranty and its performance of its obligations thereunder has
been duly taken.

2.    The execution, delivery and performance of the Guaranty and the
transactions contemplated thereby by the Guarantor require no action by or in
respect of, or filing, recording or enrolling with, any governmental body,
agency, court official or other authority, and do not contravene, or constitute
a default under, any provision of applicable law or regulation or its
constitutive documents or other internal regulations or of any agreement,
judgment, injunction, order, decree or other instrument binding upon the
Guarantor or any of its assets.

3.    The claim of the Purchaser against the Guarantor under the Guaranty will
rank at least pari passu with the claims of all its other unsecured creditors.


                                       71
<PAGE>

4.    In any proceedings taken in the United States in relation to the Guaranty,
the choice of California law by the Guarantor as the governing law of, and the
submission to jurisdiction under, the Guaranty will be recognized and enforced.

5.    The obligations expressed to be assumed by the Guarantor in the Guaranty
are legal and valid obligations binding on it and enforceable in accordance with
its terms.

6.    No deduction or withholding (whether on account of tax or otherwise) will
be required from any payment by the Guarantor arising out of or under the
Guaranty.

      For purposes of this opinion, I have assumed:

      (i)    the authenticity and completeness of all documents submitted to us
as copies;

      (ii)   the authenticity of all signatures and seals of parties; and

      (iii)  the conformity to complete original documents of all
             documents submitted to us as copies or facsimiles.

      This opinion must be read subject to the following qualifications:

      (a)    I neither express nor imply any opinion as to laws other than the
laws of the United States, the laws of the State of California and the General
Corporation Law of the State of Delaware as at the date of this opinion.

      (b)    Enforcement may be limited by any laws from time to time in effect
relating to bankruptcy, insolvency, liquidation, receivership, reconstruction,
reorganization, moratorium or other similar laws affecting creditors' rights
generally.

      This opinion is given solely for your benefit, and except with my prior
written consent is not to be disclosed to or relied on by any other person.
This opinion is limited to the matters stated herein and is not to be construed
as extending by implication to any other matter.

                                   Very truly yours,


                                       72

                                                                  EXECUTION COPY


                                    GUARANTY


     THIS GUARANTY, dated as of June 28, 1995, is executed by LAM RESEARCH
CORPORATION, a Delaware corporation ("GUARANTOR"), in favor of ABN AMRO BANK
N.V. ("PURCHASER").


                                    RECITALS

     A.   At the request of Guarantor, Purchaser, acting through its Tokyo
Branch, has entered into a Supplemental Receivables Purchase Agreement dated as
of June 28, 1995 (the "SUPPLEMENTAL PURCHASE AGREEMENT") with Purchaser and Lam
Research Co., Ltd., a Japanese corporation which is a wholly-owned subsidiary of
Guarantor ("SELLER"), pursuant to which (i) Purchaser has agreed to purchase
from Seller a certain account, promissory note or other obligation payable to
Seller (the "RECEIVABLE") upon the terms and subject to the conditions set forth
in the Supplemental Purchase Agreement and (ii) Seller has agreed to act as
collection agent for the Receivable so purchased by Purchaser from Seller (the
"PURCHASED RECEIVABLE").

     B.   Purchaser's obligation to purchase the Receivable from Seller under
the Supplemental Purchase Agreement is subject, among other conditions, to
receipt by Purchaser of this Guaranty, duly executed by Guarantor.


                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Guarantor hereby agrees with Purchaser as follows:

     1.   DEFINITIONS AND INTERPRETATION.

          (a)  DEFINITIONS.  Unless otherwise indicated in this Guaranty, each
     term set forth in SCHEDULE 1, when used in this Guaranty, shall have the
     respective meaning given to

<PAGE>

     that term in SCHEDULE 1 or in the provision of this Guaranty referenced in
     SCHEDULE 1.

          (b)  OTHER INTERPRETIVE PROVISIONS.  Headings in this Guaranty are for
     convenience of reference only and are not part of the substance hereof.
     All terms defined in this Guaranty in the singular form shall have
     comparable meanings when used in the plural form and VICE VERSA.  This
     Guaranty shall be governed by and construed in accordance with the laws of
     the State of California without reference to conflicts of law rules.
     References in this Guaranty to any document, instrument or agreement
     (i) shall include all exhibits, schedules and other attachments thereto,
     (ii) shall include all documents, instruments or agreements issued or
     executed in replacement thereof and (iii) shall mean such document,
     instrument or agreement, or replacement or predecessor thereto, as amended,
     modified and supplemented from time to time and in effect at any given
     time.

     2.   CONTINUING GUARANTY.  Guarantor unconditionally guarantees and
promises to pay and perform as and when due, upon the demand of Purchaser, (a)
all obligations of the obligor under the Purchased Receivable ("BUYER") and (b)
all obligations of Seller under the Supplemental Purchase Agreement and all
other documents, instruments and agreements delivered to Purchaser in connection
therewith (collectively, including this Guaranty, the "TRANSACTION DOCUMENTS")
(all such obligations, including the obligations described in CLAUSE (a) above,
to be referred to herein collectively as the "GUARANTEED OBLIGATIONS").
Guarantor shall make all payments required hereunder to Purchaser, or its order,
at Purchaser's office located at the address set forth in SUBPARAGRAPH 8(a)
hereof, or at such other office as Purchaser may designate, on demand in such
lawful currency as is required by SUBPARAGRAPH 8(d) hereof.  Notwithstanding any
termination of this Guaranty in accordance with PARAGRAPH 6 hereof, this
Guaranty shall continue to be in full force and effect and applicable to any
Guaranteed Obligations arising thereafter which arise because prior payments of
Guaranteed Obligations are rescinded or otherwise required to be surrendered by
Purchaser after receipt.  The liability of Guarantor hereunder is independent of
the obligations of Seller and Buyer, and a separate action or actions may be
brought and prosecuted against Guarantor irrespective of whether action is
brought against


                                        2
<PAGE>

Seller, Buyer or any other guarantor of the Guaranteed Obligations or whether
Seller, Buyer or any other guarantor of the Guaranteed Obligations is joined in
any such action or actions.  This Guaranty is a guaranty of payment and not of
collection.

<PAGE>

change in the financial condition of Seller, Guarantor, Buyer or any other
guarantor of the Guaranteed Obligations since the date hereof, and without
affecting or impairing in any way the liability of Guarantor hereunder, from
time to time to (a) purchase from Seller new Receivables and create new
Guaranteed Obligations, and, either before or after receipt of notice of
revocation, renew, compromise, extend, accelerate or otherwise change the time
for payment or performance of, or otherwise change the terms of the Purchased
Receivable and Guaranteed Obligations or any part thereof, including increase or
decrease of the rate of interest or discount thereon; (b) take and hold security
for the payment or performance of the Purchased Receivable and Guaranteed
Obligations and exchange, enforce, waive or release any such security; (c) apply
such security and direct the order or manner of sale thereof; (d) purchase such
security at public or private sale; (e) otherwise exercise any right or remedy
it may have against Seller, Guarantor, Buyer, any other guarantor of the
Guaranteed Obligations or any security, including, without limitation, the right

compromise with, release or substitute any one or more makers, endorsers or

     6.   WAIVERS.  Guarantor waives (a) any right to require Purchaser to
(i) proceed against Seller, Buyer or any other guarantor with respect to the
Guaranteed Obligations, (ii) proceed against or exhaust any security received
from Seller, Buyer or any other guarantor with respect to the Guaranteed
Obligations, or (iii) pursue any other remedy in Purchaser's power whatsoever;
(b) any defense arising by reason of the application by Seller of the proceeds
of any purchase; (c) any defense resulting from the absence, impairment or loss
of any right of reimbursement, subrogation, contribution or other right or
remedy of Guarantor against Seller, Buyer, any other guarantor with respect to
the Guaranteed Obligations or any security, whether resulting from an election
by Purchaser to foreclose upon security by nonjudicial sale, or otherwise;
(d) any setoff or counterclaim of Seller or any defense which results from any
disability or other defense of Seller or the cessation or stay of enforcement
from any cause whatsoever of the liability of Seller (including, without
limitation, the lack of


                                        7
<PAGE>

validity or enforceability of any Transaction Document); (e) any right to
exoneration of sureties which would otherwise be applicable; (f) until all
obligations of Purchaser under the Transaction Documents have been terminated
and the Guaranteed Obligations have been fully satisfied, any right of
subrogation or reimbursement and, if there are any other guarantors of the
Guaranteed Obligations, any right of contribution, and right to enforce any
remedy which Purchaser now has or may hereafter have against Seller, and any
benefit of, and any right to participate in, any security now or hereafter
received by Purchaser; (g) all presentments, demands for performance, notices of
non-performance, notices delivered under the Supplemental Purchase Agreement or
any other Transaction Document, protests, notice of dishonor, and notices of
acceptance of this Guaranty and of the existence, creation or incurring of new
or additional Purchased Receivable or Guaranteed Obligations and notices of any
public or private foreclosure sale; (h) the benefit of any statute of
limitations to the extent permitted by law; (i) any appraisement, valuation,
stay, extension, moratorium redemption or similar law or similar rights for
marshalling; (j) any right to be informed by Purchaser of the financial
condition of Seller, Buyer or any other guarantor with respect to the Guaranteed
Obligations or any change therein or any other circumstances bearing upon the
risk of nonpayment or nonperformance of the Purchased Receivable or Guaranteed
Obligations; and (k) any right to revoke this Guaranty prior to the termination
of the Transaction Documents and the satisfaction in full of all the Guaranteed
Obligations.  Guarantor has the ability and assumes the responsibility for
keeping informed of the financial condition of Seller, the Buyers and any other
guarantors of the Guaranteed Obligations and of other circumstances affecting
such nonpayment and nonperformance risks.  Without limiting the scope of any of
the foregoing waivers, Guarantor hereby waives (i) all rights and defenses
arising out of an election of remedies by Purchaser, even though that election
of remedies, such as a nonjudicial foreclosure with respect to security for a
Guaranteed Obligation, has destroyed Guarantor's rights of subrogation and
reimbursement against Seller by the operation of Section 580d of the Code of
Civil Procedure or otherwise, (ii) all rights and defenses Guarantor may have by
reason of protection afforded to Seller with respect to the Guaranteed
Obligations pursuant to the antideficiency or other laws of California limiting
or discharging the Guaranteed Obligations, including, without limitation,
Section 580a, 580b, 580d, or 726 of the California


                                        8
<PAGE>

Code of Civil Procedure, and (iii) all other rights and defenses available to
Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil
Code.

     7.   SUBORDINATION.  Guarantor hereby subordinates any obligations of
Seller to Guarantor (the "SUBORDINATED OBLIGATIONS") to the Guaranteed
Obligations as provided in this PARAGRAPH 7.  Until the occurrence of a
Potential Termination Event or Termination Event, Guarantor may receive
regularly scheduled payments from Seller on account of Subordinated Obligations.
Upon the occurrence and during the continuance of any Potential Termination
Event or Termination Event, however:

          (a)  Purchaser shall be entitled to receive payment of all Guaranteed
     Obligations before Guarantor receives payment of any Subordinated
     Obligations;

          (b)  Any payments on the Subordinated Obligations, if Purchaser so
     requests, shall be collected, enforced and received by Guarantor as trustee
     for Purchaser and be paid over to Purchaser on account of the Guaranteed
     Obligations, but without reducing or affecting in any manner the liability
     of Guarantor under the other provisions of this Guaranty; and

          (c)  Purchaser is authorized and empowered (but without any obligation
     to so do), in its discretion, (i) in the name of Guarantor, to collect and
     enforce, and to submit claims in respect of, the Subordinated Obligations
     and to apply any amounts received thereon to the Guaranteed Obligations and
     (ii) to require Guarantor (A) to collect and enforce, and to submit claims
     in respect of, the Subordinated Obligations and (B) to pay any amounts
     received on such Subordinated Obligations to Purchaser for application to
     the Guaranteed Obligations.

                     Facsimile:  (510) 661-1586

          (b)  EXPENSES.  Guarantor shall pay on demand, whether or not any
     Receivable is purchased under the Transaction Documents, (i) all reasonable
     fees and expenses, including reasonable attorneys' fees and expenses,
     incurred by Purchaser in connection with the preparation, execution and
     delivery of, and the exercise of its duties under, this Guaranty and the
     other Transaction Documents, and the preparation, execution and delivery of
     amendments and waivers hereunder and thereunder; and (ii) all reasonable
     fees and expenses, including reasonable attorneys' fees and


                                       10
<PAGE>

     expenses, incurred by Purchaser in the enforcement or attempted enforcement
     of this Guaranty or any of the Guaranteed Obligations or in preserving any
     of Purchaser's rights and remedies (including, without limitation, all such
     fees and expenses incurred in connection with any "workout" or
     restructuring affecting the Transaction Documents or the Guaranteed
     Obligations or any bankruptcy or similar proceeding involving Guarantor,
     Seller or any of their affiliates).

          (c)  INDEMNIFICATIONS.  To the fullest extent permitted by law,
     Guarantor agrees to protect, indemnify, defend and hold harmless Purchaser
     and its affiliates and their respective directors, officers, employees,
     agents and advisors ("INDEMNITEES") from and against any and all
     liabilities, losses, damages or  expenses of any kind or nature and from
     any and all suits, claims or demands (including in respect of or for
     reasonable attorney's fees and other expenses) arising on account of or in
     connection with any matter or thing or action or failure to act by
     Indemnitees, or any of them, arising out of or relating to this Guaranty or
     the other Transaction Documents, including without limitation any use by
     Guarantor of any proceeds of any Receivable purchases, except to the extent
     such liability arises from the willful misconduct or gross negligence of
     the Indemnitees.  Upon receiving knowledge of any suit, claim or demand
     asserted by a third party that Purchaser believes is covered by this
     indemnity, Purchaser shall give Guarantor reasonable notice of the matter
     and an opportunity to defend it, at Guarantor's sole cost and expense, with
     legal counsel satisfactory to Purchaser.  Any failure or delay of Purchaser
     so to notify Guarantor of any such suit, claim or demand shall not relieve
     Guarantor of its obligations under this SUBPARAGRAPH 8(C) but shall reduce
     such obligations to the extent of any increase in those obligations caused
     solely by such failure or delay.  The obligations of Guarantor under this
     SUBPARAGRAPH 8(C) shall survive the payment and performance of the
     Guaranteed Obligations.

          (d)  CURRENCY OF PAYMENT.

               (i)  Guarantor shall make all payments of the Guaranteed
          Obligations hereunder in the currency in


                                       11
<PAGE>

          which such Guaranteed Obligations are required to be paid by Seller
          pursuant to the other Transaction Documents and shall make all other
          payments hereunder in the lawful currency of the United States.

              (ii)  If any sum due from Guarantor under this Guaranty or any
          order or judgment given or made in relation hereto has to be converted
          from the currency (the "first currency") in which the same is payable
          hereunder or under such order or judgment into another currency (the
          "second currency") for the purpose of (A) making or filing a claim or
          proof against Guarantor with any Governmental Authority, (B) obtaining
          an order or judgment in any court or other tribunal or (C) enforcing
          any order or judgment given or made in relation hereto, Guarantor
          shall, to the fullest extent permitted by law, indemnify and hold
          harmless each of the Persons to whom such sum is due from and against
          any loss suffered as a result of any discrepancy between (1) the rate
          of exchange used for such purpose to convert the sum in question from
          the first currency into the second currency and (2) the rate or rates
          of exchange at which such Person may, using reasonable efforts in the
          ordinary course of business, purchase the first currency with the
          second currency upon receipt of a sum paid to it in satisfaction, in
          whole or in part, of any such order, judgment, claim or proof.  The
          foregoing indemnity shall constitute a separate obligation of
          Guarantor distinct from its other obligations hereunder and shall
          survive the giving or making of any judgment or order in relation to
          all or any of such obligations.

          (e)  WAIVERS; AMENDMENTS.  Any term, covenant, agreement or condition
     of this Guaranty may be amended or waived if such amendment or waiver is in
     writing and is signed by Guarantor and Purchaser.  No failure or delay by
     Purchaser in exercising any right hereunder shall operate as a waiver
     thereof or of any other right nor shall any single or partial exercise of
     any such right preclude any other further exercise thereof or of any other
     right.  Unless otherwise specified in such waiver or consent, a waiver or
     consent given hereunder shall be effective only in the


                                       12
<PAGE>

     specific instance and for the specific purpose for which given.

          (f)  ASSIGNMENTS.  This Guaranty shall be binding upon and inure to
     the benefit of Guarantor and Purchaser and their respective successors and
     permitted assigns, except that Guarantor may not assign or transfer any of
     its rights or obligations under this Guaranty without the prior written
     consent of Purchaser.  All references in this Guaranty to any Person shall
     be deemed to include all successors and assigns of such Person.

          (g)  CUMULATIVE RIGHTS, ETC.  The rights, powers and remedies of
     Purchaser under this Guaranty shall be in addition to all rights, powers
     and remedies given to Purchaser by virtue of any applicable law, rule or
     regulation of any Governmental Authority, the other Transaction Documents
     or any other agreement, all of which rights, powers, and remedies shall be
     cumulative and may be exercised successively or concurrently without
     impairing Purchaser's rights hereunder.

          (h)  PAYMENTS FREE OF TAXES, ETC.  All payments made by Guarantor
     under this Guaranty shall be made by Guarantor free and clear of and
     without deduction for any and all present and future taxes, levies,
     charges, deductions and withholdings.  In addition, Guarantor shall pay
     upon demand any stamp or other taxes, levies or charges of any jurisdiction
     with respect to the execution, delivery, registration, performance and
     enforcement of this Guaranty.  If any taxes, levies, charges or other
     amounts are required to be withheld from any amounts payable to Purchaser
     hereunder, the amounts so payable to Purchaser shall be increased to the
     extent necessary to yield to Purchaser (after payment of all such amounts)
     any such amounts payable hereunder in the amounts specified in this
     Guaranty.  Upon request by Purchaser, Guarantor shall furnish evidence
     satisfactory to Purchaser that all requisite authorizations and approvals
     by, and notices to and filings with, governmental authorities and
     regulatory bodies have been obtained and made and that all requisite taxes,
     levies and charges have been paid.

          (i)  PARTIAL INVALIDITY.  If at any time any provision of this
     Guaranty is or becomes illegal, invalid or unenforceable in any respect
     under the law or any jurisdiction, neither the legality, validity or
     enforceability of the remaining provisions of this Guaranty nor the
     legality, validity or enforceability of such provision under the law of any
     other jurisdiction shall in any way be affected or impaired thereby.

          (j)  JURY TRIAL.  EACH OF GUARANTOR AND PURCHASER, TO THE FULLEST
     EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT TO
     TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
     COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY.

          (k)  SUBMISSION TO JURISDICTION.  Guarantor hereby irrevocably and
     unconditionally:

               (i)  Submits for itself and its property in any legal action or
          proceeding relating to this Guaranty, or for recognition and
          enforcement of any judgment in respect thereof, to the non-exclusive
          jurisdiction of the courts of the State of California and the courts
          of the United States of America for the Northern District of
          California, and consents and agrees to suit being brought in such
          courts as Purchaser may elect;

              (ii)  Waives any objection that it may now or hereafter have to
          the venue of any such action or proceeding in any such court or that
          such proceeding was brought in an inconvenient court and agrees not to
          plead or claim the same; and

              (iii) Agrees that nothing herein shall affect Purchaser's right to
          effect service of process in any manner permitted by law, and that
          Purchaser shall have the right to bring any legal proceedings
          (including a proceeding for enforcement of a judgment entered by any
          of the aforementioned courts) against Guarantor in such courts or in
          any other court or jurisdiction in accordance with applicable law.

     IN WITNESS WHEREOF, Guarantor has caused this Guaranty to be executed as of
the day and year first above written.

FISCAL 1995 VS. 1994

Lam's net sales for fiscal year 1995 increased to $798.2 million, a 65%
increase from the prior year, as the Company continued to participate
strongly in the worldwide expansion of the semiconductor chip market.
Approximately two-thirds of the increase was due to increased unit shipments
of the Company's Rainbow and TCP product lines, with shipments of the more
advanced TCP products rising at a slightly higher rate when compared to the
prior year. Of the remaining increase, approximately half was due to the
first volume shipments of the Company's Alliance cluster tool, with most of
that product's revenue growth occurring in the last two quarters of the
fiscal year. Increased spares and service revenue, resulting from the
Company's growing installed base, accounted for most of the remainder of the
sales increase, with spares and service revenue representing 20% of the
Company's total revenue. Geographically, for the first time in its history,
more than half of the Company's revenues came from foreign customers, with
foreign sales representing 54.0% of total revenue, up from 48.4% in the prior
year. During fiscal year 1995, the Company commenced direct sales of its TCP
products to customers in Japan, which accounted for almost 41.5% of the TCP
product lines' growth over the prior year. These sales are Japanese
yen-denominated (the only significant sales which are not U.S.
dollar-denominated) and the Company's practice is to enter into yen forward
exchange contracts at or near the date purchase orders for TCP systems are
received from Japanese customers in order to minimize the subsequent foreign
exchange fluctuations. Korea continued to be the Company's largest single
foreign market and accounted for 16.3% and 15.1% of net sales in fiscal 1995
and 1994, respectively, and sales to European customers increased by over 47%
from the prior year.

   Royalty income increased by 40.3% from fiscal year 1994 due to increased
sales of systems incorporating Lam technology by Tokyo Electron Limited (TEL)
and Sumitomo Metal Industries, Ltd. (Sumitomo). The Company believes that
sales of systems incorporating the Company's technologies to Japanese
customers and royalty income derived therefrom will continue to fluctuate on
a quarterly and annual basis.

   Gross margin for fiscal 1995 was 48.3% compared to 46.2% for the prior
year. The improvement in gross margin was due in approximately equal measure
to lower unit manufacturing costs and lower installation and warranty costs.
Most of the decrease in unit manufacturing costs was due to reduced average
material costs as a result of higher volume purchasing (material costs
represent a relatively high percentage of total costs). Reductions in
installation and warranty costs were achieved as a result of active cost
reduction programs, increased training of field service and customer
personnel, as well as ongoing system design improvements.

   Research and development (R&D) spending dollars increased by 67% in fiscal
1995 over fiscal 1994, and as a percentage of total revenues, increased
slightly to 15.8%, up from 15.5% for the prior fiscal year. The Company
operates in a constantly changing and highly competitive market, and
therefore the Company believes it is critical to continue to make its
investment in R&D programs in order to maintain its position as a technology
leader. During fiscal year 1995, the Company opened a major new R&D facility
at its Fremont, California campus and continued to add scientific and
engineering personnel to staff its ongoing development


                                               Lam Research Corporation / 17

projects, which included improvements to its existing etch products,
continued development of its cluster tool and chemical vapor deposition (CVD)
products, and new product development, including the flat panel display
system.

   Selling, general and administrative (S,G&A) expenses increased by 60% in
fiscal 1995 over fiscal 1994, but continued to decrease as a percentage of
total revenue to 17.9% from 18.5% for the prior fiscal year. The Company
added significant facilities and information technology infrastructure in
fiscal 1995 to accommodate the rapidly expanding growth in its sales, field
service, customer support, and administration areas as a result of the
increased sales volume. S,G&A headcount increased by 57% in fiscal 1995 over
fiscal 1994. The Company now occupies twelve major buildings in Fremont,
California and has expanded its foreign operations, which are primarily sales
and service offices.

   Interest expense increased by 30.6% over the prior fiscal year, due to
additional yen-based borrowings by its Japanese subsidiary, additional
interest expense related to an interest rate swap described in Note D to the
consolidated financial statements, and the increased acquisition of equipment
under capital leases. Interest income increased due to the investment of the
proceeds of a public offering of the Company's common stock completed in the
first quarter of fiscal 1995. Other income includes a $10.4 million gain
recorded in the fourth quarter of fiscal 1995 from the sale of stock held in
Brooks Automation, Inc., a vendor of the Company.

   The combined effective tax rate for fiscal 1995 of 30% decreased over the
prior year's 34% due to an increase in benefits resulting from federal and
state research and other tax credits. The Company expects its effective tax
rate to rise slightly in fiscal 1996 as the tax credits become a smaller
percentage of the Company's tax liability. The Company believes its future
income will be sufficient to realize its net deferred tax assets.

FISCAL 1994 VS. 1993

Lam's net sales for fiscal year 1994 increased to $484.9 million, an 86%
increase from the prior year. The Company's increased net sales were driven
by strong sales of the Company's Rainbow and TCP etch product lines, and, to
a lesser extent, by the addition of etch product lines acquired from Drytek,
Inc. in July 1993. Sales of the Company's etch systems, principally Rainbow
and TCP products, contributed approximately 76% of the Company's revenue in
fiscal 1994 compared with 78% in 1993. The increase in etch product sales in
fiscal 1994 reflected strong growth across all three of Lam's major etch
applications (polysilicon, oxide and metal), as well as the ongoing
transition of semiconductor manufacturers to more advanced products and
processes. As a result, sales of TCP products to support these manufacturers'
requirements grew at a faster rate than Rainbow products. Average machine
selling prices increased 18% over the prior year, as TCP systems have
significantly higher average sell-ing prices than Rainbow systems, and unit
machine sales increased by 59% over the prior year. Spares and service
revenue increased 74% as a result of the Company's expanding installed
machine base and represented approximately 19% of the Company's net sales.
Geographically, foreign sales represented 49% of net sales in fiscal 1994
compared to 47% in fiscal 1993, based on strong net sales growth in the Asia
Pacific region and Europe. Major multi-unit shipments to Korean customers
accounted for the largest portion of the increase. Substantially all of the
Company's export sales in fiscal 1994 were denominated in the U.S. dollar.
Royalty income increased by 92% from fiscal 1993 due to increased sales of
systems incorporating its technology by TEL and Sumitomo.

   Gross margin for fiscal 1994 was 46.2% compared to 47.2% for the prior
fiscal year. The decline in margin reflected higher provision for
installation and warranty expenses due in part to the strong sales of the
Company's new TCP machines in fiscal 1994, as well as increased provisions
for excess and obsolete inventories, particularly spare parts inventories
related to the Company's expansion of its operations worldwide. To a lesser
extent, the lower gross margin in fiscal 1994 reflects discounts on certain
multi-unit orders from Korean customers, and increased sales of Rainbow
modules at low margins to Sumitomo in Japan. These factors were offset in
part by increased margins for Lam's mature Rainbow machines due to higher
average selling prices and by an increase in spare parts and service margins.

   R&D spending, net of third party funding, increased by 74% in fiscal 1994
over fiscal 1993, although as a percentage of total revenues, it decreased to
15.5%, slightly less

than fiscal year 1993. The increased spending was due to enhancements of
existing etch and deposition products.

   S,G&A expenses increased by 72% in fiscal 1994 over fiscal 1993, but
decreased as a percentage of total revenue to 18.5% from 20.0%. The Company
added employees in all S,G&A areas to accommodate the increased sales volume,
in particular in field service and customer support, both in the United
States and in its foreign sales and service subsidiaries. Fiscal year 1994
marked the first full year of operation for the Company's development center
in Japan. The Company also established a new customer and employee training
facility at its Fremont headquarters, and facility-related expenses in
general have risen due to increasing employee headcount.

   The increase in other expense from fiscal 1993 to fiscal 1994 was due
primarily to higher interest expense resulting from the Company's May 1993
$66 million convertible subordinated debenture offering. The effective tax
rate for fiscal 1994 of 34% increased over the prior year's 30% due primarily
to a decrease in estimated business tax credits available for use in fiscal
1994 and the 1% income tax rate increase as a result of passage of the
Revenue Reconciliation Act of 1993.

LIQUIDITY AND CAPITAL RESOURCES

Operating activities provided approximately $19.1 million in cash flows for
fiscal 1995. Approximately $112.7 million of net cash was generated from net
income plus non-cash depreciation and amortization, which was partially
offset by increases in accounts receivable and inventories less increases in
trade accounts payable and accrued expenses, all such increases being due to
the Company's increased sales volume. During fiscal year 1995, the Company
entered into two agreements with banks which allow the Company to sell up to
$70.0 million of yen-denominated accounts receivable to the banks. At June
30, 1995, $37.6 million of receivables had been sold to the banks, with $30.1
million still uncollected by the banks and subject to recourse provisions.

   Net cash used in investing activities for fiscal 1995 was $124.7 million,
primarily for capital expenditures including acquisition of equipment used
in manufacturing and research and development and construction of
demonstration labs and leasehold improvements. In July 1995, the Company
completed construction of a new manufacturing facility in Korea which is
expected to supply a portion of the systems requirements of the Company's
customers there by the end of fiscal 1996. Other uses of cash in investing
activities included purchases of short-term investments totaling $58.2
million (net of sales). The short-term investments consisted primarily of
money market preferred issues and floating rate municipal bonds which had
terms of less than 90 days.

   In addition to internally generated sources of cash flows, the Company
completed a public offering of its Common Stock during the first quarter of
fiscal 1995, raising $115.0 million from the sale of 3,100,000 shares.
Additionally, the Company made primarily Japanese yen-denominated borrowings
totaling approximately $9.5 million during fiscal 1995.

   As of June 30, 1995, the Company had $101.0 million in cash, cash
equivalents and short-term investments compared with $38.3 million at June
30, 1994. The Company also had $50.0 million available under four bank lines
of credit which expire between September 1995 and June 1996; the Company
expects to negotiate extensions on all of the lines of credit upon
substantially similar terms. Borrowings under the lines are unsecured. There
were no outstanding borrowings on the lines at June 30, 1995.

   During fiscal 1994, the Company entered into a lease for a new research
and development facility at its Fremont headquarters. Under the terms of a
pledge agreement related to this lease, the Company is required to provide
collateral (restricted investments) equal to 110% of the construction costs.
The restricted investments were $25.0 million at June 30, 1995. The Company
is currently renegotiating the pledge agreement to reduce the amount of
restricted investments.

   The Company's commitments consist primarily of debt obligations and
operating and capital lease commitments for its facilities and equipment.
Based upon current forecasts, the Company's cash, cash equivalents,
short-term investments and available lines of credit at June 30, 1995 should
be sufficient to support anticipated levels of operations and capital
expenditures through June 30, 1996.

Notes to Consolidated Financial Statements
June 30, 1995

   -------------------------------------------
A  Summary of Significant Accounting Policies

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All intercompany accounts and transactions
have been eliminated in consolidation.

CASH EQUIVALENTS

All highly liquid investments purchased with an original maturity of three
months or less are considered to be cash equivalents.

INVESTMENTS

Effective July 1, 1994, the Company adopted Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities" (FAS 115), which requires investments in debt and marketable
equity securities to be classified as either held-to-maturity, trading or
available-for-sale. The Company reviewed its portfolio and determined that
its investments are to be classified as either available-for-sale or
held-to-maturity. Under FAS 115, securities classified as available-for-sale
are stated at fair value and any difference between an investment's cost and
its fair value is recorded in stockholders' equity. Debt securities
classified as held-to-maturity are stated at amortized cost.

INVENTORIES

Inventories are stated at the lower of cost (first-in, first-out method) or
market. The Company adjusts the carrying value of excess or obsolete
inventory as appropriate.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS

Equipment and leasehold improvements are stated at cost. Equipment is
depreciated by the straight-line method over the estimated useful lives of
the assets, generally three to five years. Leasehold improvements are
amortized by the straight-line method over the shorter of the life of the
related asset or the term of the lease. Amortization of equipment under
capital leases is included with depreciation.

REVENUE RECOGNITION

Sales of the Company's products are generally recorded upon shipment.
Estimated costs to be incurred by the Company related to product installation
and warranty fulfillment are accrued at the date of shipment.

FOREIGN CURRENCY

The Company has foreign sales and service operations. With respect to all
foreign subsidiaries excluding Japan, the functional currency is the U.S.
dollar and transaction and translation gains and losses are included in net
income and have not been material in any year presented. Due to the changing
nature of the operation of the Company's Japanese subsidiary, effective
January 1, 1994, the Company determined that the functional currency of this
subsidiary is the Japanese yen. Accordingly, translation gains and losses
related to the Japan subsidiary are included as a component of stockholders'
equity subsequent to January 1994, but have not been material through June
30, 1995.

INCOME PER SHARE

Income per share computations are based upon the weighted average number of
shares of Common Stock and common stock equivalents outstanding during the
year. The common stock equivalents include shares issuable upon the assumed
exercise of the stock options reflected under the treasury stock method. The
convertible subordinated debentures are not common stock equivalents and,
accordingly, are excluded from the calculation of primary income per share.
Fully diluted income per share includes the effect of the convertible
subordinated debentures and net income is adjusted to reflect the exclusion
of net interest expense and net amortization expense of debt issuance costs
related to the debentures assuming their conversion at the beginning of the
period.

INCOME TAXES

In February 1992, the Financial Accounting Standards Board issued FAS No.
109, "Accounting for Income Taxes." The Company adopted the provisions of the
standard as of July 1, 1993, the beginning of fiscal year 1994. Adoption of
FAS 109 had no current or cumulative impact on the Company's income at the
date of adoption. As permitted by FAS 109, the Company has elected not to
restate the financial statements for the years prior to adoption.

   -------------------------------------------
B  Company and Industry Information

Lam Research Corporation is a leading supplier of technically complex thin
film processing equipment used in primary stages of semiconductor
manufacturing. The Company's product offerings include single wafer plasma
etch systems with a wide range of applications and chemical vapor deposition
(CVD) systems. The Company sells its products primarily to large companies
involved in the production of semiconductors in the United States, Europe,
Japan and Asia Pacific. Credit evaluations are performed on all customers and
the Company usually does not require collateral on sales.

   During fiscal 1995, the Company entered into two agreements totaling
approximately $70,000,000 to sell specific Japanese yen-denominated
receivables subject to recourse provisions. At June 30, 1995, $37,612,000 of
receivables had been sold to the bank, of which $30,107,000 remained
uncollected by the bank at June 30, 1995.

   One customer accounted for 11%, 14% and 15% of sales for fiscal 1995, 1994
and 1993, respectively. Another customer accounted for 10% of sales for
fiscal 1994.

   The Company operates in four geographic regions, the United States,
Europe, Japan and Asia Pacific. The following is a summary of local
operations by geographic region at June 30:

C  Financial Instruments

During fiscal 1995, the Company adopted FAS 115 "Accounting for Certain
Investments in Debt and Equity Securities."

   Due to insignificant differences at the date of adoption of FAS 115
between cost and fair value of the Company's investments in debt and equity
securities, the adoption of FAS 115 had no effect on the Company's financial
statements. In accordance with FAS 115, prior period financial statements
have not been restated.

   Investments at June 30, 1995 are comprised of the following:

Company for similar debt instruments of the same remaining maturities.

   During the fourth quarter of fiscal 1995, the Company sold all of its
shareholdings of Brooks Automation, Inc., (Brooks) for a pre-tax gain of
$10,399,000, which is included as other income. At June 30, 1995, the
receivable related to the sale of these securities is included in other
current assets. The shares the Company sold were included as part of a Brooks
secondary public offering of common stock on June 27, 1995. Roger Emerick,
the Company's Chief Executive Officer, serves on the board of directors of
Brooks.

   -------------------------------------------
D  Derivative Financial Instruments

During fiscal 1995, the Company adopted Statement of Financial Accounting
Standards No. 119, "Disclosure about Derivative Financial Instruments and
Fair Value of Financial Instruments" (FAS 119).

   The Company enters into forward foreign currency exchange contracts to
hedge the value of Japanese yen-denominated sales transactions against
fluctuations in exchange rates. The purpose of entering into these forward
yen contracts is to attempt to minimize the impact of exchange rate
fluctuations on the value of the yen-denominated assets and liabilities.
Substantially all forward contracts entered into by the Company have
maturities of 360 days or less. The realized and unrealized gains and losses
on these contracts are deferred and are offset against realized and
unrealized gains and losses from the settlement of the related yen
receivables. At June 30, 1995, the Company had forward contracts to sell
$30,701,000 in Japanese yen. The unrealized gain on these contracts at June
30, 1995 was $464,000. The realized losses on forward yen contracts during
fiscal 1995 were offset by underlying gains on the receivables. At June 30,
1994, the outstanding face amounts of currency forward contracts was
approximately $8,000,000, all of which hedge Japanese yen purchase
commitments from Japanese customers.

   In May 1993, the Company entered into a three year interest-rate swap
agreement with a third party which is scheduled to mature in May 1996. Under
the agreement the third party is assuming 4.5% of the 6% fixed interest rate
payments related to the Company's $66,000,000 convertible subordinated
debentures while the Company is assuming variable interest rate (equal to the
six-month London Interbank Offered Rate (LIBOR), 6.375% at June 30, 1995)
payments of the third party on a like principal amount. The net amount of
interest payments assumed by the third party and interest payments made by
the Company is included in interest expense. The fair value of the liability
related to the Company's interest rate swap was $1,216,000 at June 30, 1995.

G  Other Assets

Patents and other intangibles are amortized on a straight-line basis over
their estimated useful lives. Debt issuance costs related to the convertible
subordinated debentures issued by the Company in May 1993 are being amortized
ratably over ten years. Accumulated amortization of patents, other
intangibles, and debt issuance costs was $522,000 and $3,951,000 at June 30,
1995 and 1994, respectively. In the fourth quarter of fiscal 1995, the
Company determined the future usefulness of certain capitalized patents and
other intangibles was in significant doubt and that the carrying value of
these assets would not be realized through future cash flows. Accordingly,
the Company wrote off the net book value ($1,960,000) of these assets.

   The Company has lines of credit available with four banks totalling
$50,000,000 on which borrowings bear interest at the bank's prime rate or 1%
over either the three month LIBOR rate or Eurodollar rate. No borrowings were
outstanding at June 30, 1995 or June 30, 1994. The Company's lines of credit
restrict the Company from paying dividends. These lines expire between
September 1995 and June 1996, and the Company expects to renegotiate
extensions on all of them with similar terms.

   The notes payable to leasing companies are collateralized by equipment
additions with a cost equal to the original principal amount of the notes.

J  Incentive Stock Option Plans and
   Stock Purchase Plan

The Company has adopted incentive stock option plans that provide for the
granting to qualified employees of incentive stock options to purchase shares
of Common Stock.

Lam Research Corporation / 28

<PAGE>

In addition, the plans permit the granting of nonstatutory stock options to
paid consultants and employees and provide for the automatic grant of
nonstatutory stock options to outside directors. The option price is
determined by the Board of Directors, but in no event will it be less than
the fair market value on the date of grant (no less than 85% of the fair
market value at the date of grant in case of nonstatutory options). Options
granted under the plans vest over a period determined by the Board of
Directors. Under the automatic grant program, each outside director receives
an option exercisable for 6,000 shares of Common Stock during January of each
year with the exercise price equal to the fair market value on date of grant.

   A summary of incentive stock option plan transactions follows:

   -------------------------------------------
K  Profit Sharing Plan and Benefit Plan

During fiscal 1995, the Company revised the profit sharing plan for its
domestic employees. Distributions to employees by the Company are made
quarterly based upon a percentage of base salary provided that a threshold
level of the Company's financial performance is met. Upon achievement of the
threshold, the profit sharing is awarded based upon performance against
certain corporate financial and operating goals. Prior to fiscal 1995,
distributions to the domestic employees under the profit sharing plan were
made semi-annually based on 5% of pretax income provided certain minimum net
income goals were met. Profit sharing plan expense for fiscal 1995, 1994 and
1993 was $9,506,000, $3,008,000, and $1,422,000 respectively.

   The Company maintains a 401(k) retirement savings plan for its full-time
domestic employees. Each participant in the plan may elect to contribute 2%
to 20% of his or her annual salary to the plan, subject to statutory
limitations. Beginning January 1, 1994, the Company began to match employee
contributions to the plan at the rate of 50% of the first 6% of salary
contributed. The Company match expense for fiscal 1995 and 1994 was
$2,342,000 and $770,000, respectively.

General Signal Corporation (GSC), a New York corporation). The purchase price
was approximately $5,800,000 in cash. The assets acquired consisted primarily
of accounts receivable, inventory and fixed assets, while the liabilities
assumed consisted primarily of trade accounts payable and other specified
general liabilities. Drytek, Inc. was a manufacturer of semiconductor etch
equipment since its founding in 1980.

   -------------------------------------------
P  Litigation

In October 1993, Varian Associates, Inc. (Varian) brought suit against the
Company in the United States District Court, Northern District of California,
seeking monetary damages and injunctive relief based on the Company's alleged
infringement of certain patents held by Varian. The lawsuit is in the late
stages of discovery. The Company has asserted defenses of invalidity and
unenforceability of the patents that are the subject of the lawsuit, as well
as noninfringement of such patents by the Company's products. While
litigation is subject to inherent uncertainties and no assurance can be given
that the Company will prevail in such litigation or will obtain a license
under such patents on commercially reasonable terms or at all if such patents
are held valid and infringed by the Company's products, the Company believes
that the Varian lawsuit will not have a material adverse effect on the
Company's consolidated financial statements.

   In addition, the Company is from time to time notified by various parties
that it may be in violation of certain patents. In such cases, it is the
Company's intention to seek negotiated licenses where it is considered
appropriate. The outcome of these matters will not, in management's opinion,
have a material impact on the Company's consolidated financial position,
operating results or cash flows.

Report of Ernst & Young LLP, Independent Auditors


Board of Directors
Lam Research Corporation
Fremont, California

We have audited the accompanying consolidated balance sheets of Lam Research
Corporation as of June 30, 1995 and 1994, and the related consolidated
statements of income, stockholders' equity and cash flows for each of the
three years in the period ended June 30, 1995. These financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit 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 management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Lam Research
Corporation at June 30, 1995 and 1994, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1995, in conformity with generally accepted accounting principles.
