NOTE E --  NET LOSS PER SHARE

           All net loss amounts for all periods have been presented and, where
necessary, restated to conform to the FAS 128 requirements. Basic net loss per
share, is calculated using the weighted average number of shares of common stock
outstanding during the period. Diluted net loss per share is calculated using
the weighted average number of shares of common stock outstanding during the
period. The assumed conversion of the convertible subordinated notes to
potential common shares were excluded from the diluted earnings per share
because their effect was antidilutive. Options were outstanding during the three
month periods ended September 30, 1998 and September 30, 1997, respectively, but
were excluded from the computation of diluted net loss per common share because
the effect in periods with a net loss would be antidilutive. The Company's basic
and diluted net loss per share, as calculated according to FAS 128, are as
follows:

NOTE F -- COMPREHENSIVE LOSS

           As of July 1, 1998, the Company has adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income," ("FAS 130"). FAS
130 establishes new rules for the reporting and display of comprehensive income
and its components; however the adoption of this statement had no impact on the
Company's net loss or stockholders' equity. FAS 130 requires that unrealized
gains or losses on available-for-sale securities and foreign currency
translation adjustments are to 



                                       7

be included in other comprehensive loss. Prior to adoption, unrealized gains and
losses and foreign currency translation adjustments were reported as a component
of stockholder's equity.

The components of comprehensive loss, net of tax, are as follows:

NOTE G -- RESTRUCTURING

           During the quarters ended March 31, 1998 and June 30, 1998, the
Company announced plans to restructure its operations to focus more on its core
etch and Chemical Mechanical Planarization ("CMP") product groups, and to exit
its Flat Panel Display ("FPD") and Chemical Vapor Deposition ("CVD") operations.
As a result of the restructurings, the Company reduced its global workforce by
approximately 28% and downsized and consolidated its manufacturing operations
and facilities. The Company recorded a total restructuring charge of $148.9
million for severance compensation and benefits, the write-off of facilities,
fixed assets and excess and obsolete inventory and other exit costs. At
September 30, 1998, $30.2 million of the charge remains accrued on the balance
sheet. During the quarter ended September 30, 1998 the Company made
approximately $17 million of cash payments, relating primarily to severance,
benefits and rent on unoccupied facilities. At September 30, 1998, the Company
has approximately $28 million of future cash payments relating to the
restructurings. There will be further charges against the restructuring reserves
established in fiscal 1998 during fiscal 1999, as the Company completes this
restructuring program.

September 30, 1998.

Results of Operations

           Net sales for the first quarter of fiscal 1999 decreased 51% compared
to the first quarter of fiscal 1998. The Company experienced decreased revenues
for all of its product lines. Total foreign sales represented 42% of total
revenue during the first quarter of fiscal 1999 compared to 51% of total revenue
for the year-ago period. Revenue from the Asia Pacific and Japan regions
decreased to 15% and 6%, respectively, of total revenue during the first quarter
of fiscal 1999 from 31% and 9%, respectively of total revenue during the first
quarter of fiscal 1998. Revenue from the North America and Europe regions
increased to 58% and 21%, respectively, of total revenue during the first
quarter 



                                       9
<PAGE>   10

of fiscal 1999 from 49% and 11%, respectively, of total revenue during the first
quarter of fiscal 1998. The semiconductor industry is currently experiencing a
severe worldwide slowdown in equipment demand which was and continues to be
brought on by depressed DRAM pricing, production overcapacity as well as
uncertainty in the worldwide financial markets. The Company anticipates that net
sales will decrease, compared to the quarter ended September 30, 1998, for the
remainder of calendar 1998.

           In response to the continued decline in net sales, and as part of a
restructuring plan, the Company commenced a reduction of its work force in
November 1998. In addition, Management anticipates that as part of the
restructuring plan it will consolidate facilities. The Company has not yet
finalized its restructuring plan and therefore, it cannot quantify the
associated costs at this time. The Company will record a restructuring charge
during the fiscal quarter ending December 1998.

           Royalty income decreased 88% from the year-ago period. The Company
expects that royalty income will remain relatively flat for the remainder of the
fiscal year. The reduction in royalty income is a result of the slowdown in
equipment sales in the Japan region.

           Gross margin percentage declined to 35.3% in the first quarter of
fiscal 1999 compared with 39.0% for the year-ago period. The lower overall gross
margin percentage is primarily a result of excess manufacturing capacity which
is a result of the Company's lower volume of sales.

           Research and development ("R&D") expenses for the quarter ended
September 30, 1998 were 35.2% lower than the year-ago period. As a percentage of
total revenue R&D expenses increased to 24.7% of total revenue for the quarter
ended September 30, 1998 compared to 18.7% of total revenue for the quarter
ended September 30, 1997. The decrease in R&D expenses is a result of the
Company's efforts to exit from its FPD and CVD operations and to focus more on
its core etch and CMP product groups.

           Selling, general and administrative ("SG&A") expenses decreased 21.4%
during the first quarter of fiscal 1999 compared to the year-ago period. The
decrease in SG&A expenses is a result of the Company's restructurings in fiscal
1998. The Company continues to monitor closely its expenditures and capital
spending relative to revenue levels.

           During the first quarter of fiscal 1998, the Company recorded costs
of $17.7 million related to the merger with OnTrak Systems, Inc. ("OnTrak").
Such expenses relate to investment advisory fees, legal and accounting fees,
financial printing costs and other merger-related costs.

           Other income increased $0.8 million during the first quarter of
fiscal 1999 compared to the first quarter of fiscal 1998. During the first
quarter of fiscal 1998, the Company issued $310.0 million of convertible
subordinated notes ("the Notes") bearing interest at 5% which are due to mature
on September 1, 2002. During the first quarter of fiscal 1999, the Company's
rate of return on its investments exceeded the interest rate it pays on the
Notes.



                                       10
<PAGE>   11

           Due to the Company's significant tax loss and credit carryovers, Lam
did not record any tax benefit during the first quarter of fiscal 1999.

           During the quarters ended March 31, 1998 and June 30, 1998, the
Company announced plans to restructure its operations to focus more on its core
etch and CMP product groups, and to exit its FPD and Chemical Vapor Deposition
("CVD") operations. As a result of the restructurings, Lam reduced its global
workforce by approximately 28% and downsized and consolidated its manufacturing
operations and facilities. The Company recorded a total restructuring charge of
$148.9 million for severance compensation and benefits, the write-off of
facilities, fixed assets and excess and obsolete inventory and other exit costs.
At September 30, 1998, $30.2 million of the charge remains accrued on the
balance sheet. During the quarter ended September 30, 1998, the Company made
approximately $17 million of cash payments, relating primarily to severance,
benefits and rent on unoccupied facilities. At September 30, 1998 the Company
has approximately $28 million of future cash payments relating to the
restructurings. There will be further charges against the restructuring reserves
established in fiscal 1998 during fiscal 1999, as the Company completes its
restructuring program.

           The Company has established a team to address issues raised by the
introduction of the Single European Currency ("Euro") for initial implementation
as of January 1, 1999, and through the transition period to January 1, 2002. Lam
expects to be able to meet related legal requirements by January 1, 1999, and
through the transition period. Lam does not expect the cost of any system
modifications to be material and does not currently expect that introduction and
use of the Euro will materially affect its foreign exchange and hedging
activities or will result in any material increase in transaction costs. The
Company will continue to evaluate the impact over time of the introduction of
the Euro; however, based on currently available information management does not
believe that the introduction of the Euro will have a material adverse impact on
the Company's financial condition or the overall trends in results of its
operations.

           The Company relies heavily on its existing application software and
operating systems. The Year 2000 compliance issue (in which systems do not
properly recognize date sensitive information when the year changes to 2000)
creates risks for the Company: if internal data management, accounting and/or
manufacturing or operational software and systems do not adequately or
accurately process or manage day or date information beyond the year 1999, there
could be an adverse impact on the Company's operations. To address the issue,
the Company has assembled a task force to review and assess internal software,
data management, accounting and manufacturing and operational systems to ensure
that they do not malfunction as a result of the Year 2000 date transition. The
review and corrective measures are proceeding in parallel. These review and
corrective measures are intended to encompass all significant categories of
systems used by the Company, including data management, accounting,
manufacturing, sales, human resources and operational software and systems. The
Company is also working with its significant suppliers of products and systems
to assure that the products and systems supplied to the Company, and the
products the Company supplies to its customers, are Year 2000 compliant. With
respect to compliance of the products the Company supplies to its customers, the
Company intends to adhere to Year 2000 



                                       11
<PAGE>   12

test case scenarios established by SEMATECH, an industry group comprised of US
semiconductor manufacturers. The Company's compliance efforts are substantially
complete, and the Company currently expects that its review, corrective measures
and contingency planning (where necessary) will be complete by the end of fiscal
1999, with the goal of resolving all material internal programs and systems
prior to the Year 2000 date transition.

           In connection with its review and corrective measures, both to ensure
that its internal products and systems, and the operating systems accompanying
the products sold to its customers, are Year 2000 compliant, the Company expects
both to replace some software and systems and to upgrade others where
appropriate. As a contingency with respect to products the Company currently
offers to its customers, the Company may replace all non-compliant operating
systems with systems demonstrated to be Year 2000 compliant. With respect to
products and systems supplied to the Company for use internally, the Company may
upgrade all non-compliant products and systems and, where necessary or where no
reasonable upgrade is available, replace such non-compliant products and systems
with products and systems demonstrated to be Year 2000 compliant.

           The Company is in the process of identifying for its customers the
corrective measures necessary to ensure that its installed products are Year
2000 compliant, including compliance of third-party products (such as software)
incorporated into the Company's installed products. In this regard, the Company
is incurring, and will continue to incur throughout fiscal 1999, various costs
to provide customer support regarding Year 2000 issues, and certain of such
costs are expected to be borne not by the Company but, instead, to be passed on
to the customers. The full cost of these activities, including corrective
measures, is not fully known. However, the Company believes that the potential
future financial impact of assuring such Year 2000 compliance is not expected to
be material. The Company's failure to ensure, at all or in a timely or
reasonable manner, that its products are Year 2000 compliant may cause
disruption in the customer's ability to derive expected productivity from those
products or to integrate the products fully and functionally into certain
automated manufacturing environments. With respect to products and systems the
Company purchases for use internally, failure to ensure Year 2000 compliance may
cause disruption in the Company's automated accounting, financial planning, data
management and manufacturing operations which could have a material effect on
the Company's short-term ability to manage its day-to-day operations in an
efficient, cost-effective and reliable manner.

           The Company believes that its Year 2000 compliance project will be
completed on a timely basis, and in advance of the Year 2000 date transition and
will not have a material adverse effect on the Company's financial condition or
overall trends in the results of operations. However, there can be no assurance
that unexpected delays or problems, including the failure to ensure Year 2000
compliance by systems or products supplied to the Company by a third party, will
not have an adverse effect on the Company, its financial performance, or the
competitiveness or customer acceptance of its products. Further, the Company's
current understanding of expected costs is subject to change as the project
progresses, and does not include potential costs related to actual customer
claims, or the cost of internal software and hardware replaced in the normal
course of business (whose installation 



                                       12
<PAGE>   13

otherwise in the normal course of business may be accelerated to provide
solutions to Year 2000 compliance issues).

Liquidity and Capital Resources

           As of September 30, 1998, the Company had $391.2 million in cash,
cash equivalents, short-term investments and restricted cash, compared with
$448.5 million at June 30, 1998. The Company has a total of $100.0 million
available under a syndicated bank line of credit which is due to expire in April
2001. Borrowings under the line of credit bear interest at the bank's prime rate
or 0.55% to 0.95% over London Interbank Offered Rate.

           Net cash used in operating activities was $49.4 million for the three
months ended September 30, 1998. The Company used $36.9 million of working
capital. Cash payouts relating to the fiscal 1998 restructurings were
approximately $17 million. Decreases in accounts payable, accrued liabilities
and increases in prepaid expenses were offset by decreases in accounts
receivables and inventory resulting in a use of cash of $19.9 million. Cash
provided by investing activities was $170.0 million, which was primarily from
the net sales of short-term investments. Capital expenditures, net of
retirements, for the three month period ended September 30, 1998 were $6.3
million. The Company used $4.3 million in financing activities primarily from
the principal payments of long-term debt and capital lease obligations of $3.0
million. During the quarter ended September 30, 1998, the Company used $3.9
million for the repurchase of common stock which was offset by the sale of
common stock.

           The Company's cash, cash equivalents, short-term investments and
available lines of credit at the end of the first quarter of fiscal 1999 are
considered adequate to support current levels of operations for at least the
next twelve months.

Risk Factors

           Fluctuations in Quarterly Revenues and Operating Results

           The Company's quarterly revenues have fluctuated in the past and may
fluctuate in the future. The Company's revenues are dependent on many factors,
including, but not limited to, the economic conditions in the semiconductor
industry generally, and equipment industry specifically, customer capacity
requirements, the size and timing of the receipt of orders from customers,
customer cancellations or delays of shipments, the Company's ability to develop,
introduce and market new, enhanced and competitive products, at all and on a
timely basis, the introduction of new products by its competitors, challenges to
the Company's products and technology, changes in average selling prices and
product mix, and exchange rate fluctuations, among others. The Company's expense
levels will be based, in part, on expectations of future revenues. If revenue
levels in a particular quarter do not meet expectations, operating results could
be adversely affected.

           The Company derives its revenue primarily from the sale of a
relatively small number of high-priced systems. The Company's systems can range
in price from approximately $150,000 to over $2.5 million per unit. The sale of
fewer systems than anticipated in any 



                                       13
<PAGE>   14

quarter may have a substantial negative impact on the Company's operating
results for the quarter. The Company's results of operations for a particular
quarter could be adversely affected if anticipated orders are not received in
time to enable shipment during such quarter, if anticipated shipments are
delayed or canceled by one or more customers, or if shipments are delayed due to
procurement shortages or manufacturing difficulties. Further, as a result of the
continuing consolidation of manufacturing operations and capacity at the
Company's Fremont, California facility, natural, physical or other events
affecting the facility, including labor disruptions, could adversely impact the
Company's operations and revenue.

           Volatility in the Semiconductor Equipment Industry

           The business of the Company depends on the capital equipment
expenditures of semiconductor manufacturers, which in turn depend on the current
and anticipated market demand for integrated circuits and products utilizing
integrated circuits. The semiconductor industry has been cyclical in nature and
has historically experienced periodic downturns. During the past nine months the
semiconductor industry has been experiencing a severe slowdown of product demand
and extreme volatility in product pricing. This slowdown and volatility has
caused the semiconductor industry to reduce or delay significantly purchases of
semiconductor manufacturing equipment and construction of new fabrication
facilities. This slowdown and volatility is expected to continue throughout
fiscal 1999. As previously announced, these conditions have adversely affected
and will continue to affect materially the Company's aggregate bookings,
revenues and operating results. Even during periods of reduced revenues, in
order to remain competitive the Company will continue to invest in R&D and to
maintain extensive ongoing worldwide customer service and support capabilities,
which could adversely affect its financial results.

           Dependence on New Products and Processes; Rapid Technological Change

           Rapid technological changes in semiconductor manufacturing processes
subject the semiconductor equipment industry to increased pressure to maintain
technological parity with deep submicron process technology. The Company
believes that its future success will depend in part upon its ability to
develop, manufacture and introduce successfully new products and product lines
with improved capabilities and to continue to enhance existing products. Due to
the risks inherent in transitioning to new products, the Company will be
required to forecast accurately demand for new products while managing the
transition from older products. If new products have reliability or quality
problems, reduced orders, higher manufacturing costs, delays in acceptance of
and payment for new products and additional service and warranty expenses may
result. In the past, the Company has experienced some delays, as well as
reliability and quality problems, in connection with product introductions.
There can be no assurance that the Company will successfully develop and
manufacture new products, or that new products introduced by it will be accepted
in the marketplace. If Lam does not successfully introduce new products, the
Company's results from operations will be materially adversely affected.



                                       14
<PAGE>   15

           The Company expects to continue to make significant investments in
R&D and to explore joint development relationships with other members of the
industry. The Company must manage product transitions or joint development
relationships successfully, as introduction 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
current product offerings obsolete or that the Company will be able to develop
and introduce new products or enhancements to existing products which satisfy
customer needs in a timely manner 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 marketing and selling of advanced processes or
equipment to customers with whom it has formed strategic alliances, selling of
its existing products to those customers could be adversely affected. In
addition, in connection with the development of the Company's new products, the
Company will invest in high levels of preproduction inventory, and the failure
to complete development and commercialization of these new products in a timely
manner could result in inventory obsolescence, which could have an adverse
effect on its financial results.

           Introduction of New Product

           Lam currently anticipates shipping its Teres CMP system in fiscal
1999, which is expected to face significant competition from multiple current
and future competitors. Among the companies currently offering polishing systems
are Applied Materials, Inc., Cybeq Systems, Ebara Corporation, IPEC, SpeedFam
Corp., Strasbaugh and Sumitomo. Lam believes that other companies are developing
polishing systems and are planning to introduce new products to this market
before or during the same time frame as the Company's anticipated introduction
of its Teres CMP polishing system.

           Product Concentration; Lack of Product Revenue Diversification

           A substantial percentage of the Company's revenues to date have been
derived from a limited number of products, and such products are expected to
continue to account for a substantial percentage of the Company's revenues in
the near term. Continued market acceptance of its primary products is therefore
critical to the future success of the Company. Any decline in demand for or
failure to achieve continued market acceptance of such products or any new
version of these products, if any, as a result of competition, technological
change, failure of the Company to release new versions of these products on
time, or otherwise, could have a material adverse effect on the business,
operating results, financial condition and cash flows of the Company.

           Dependence Upon Key Suppliers and Key Distributors

           Certain of the components and subassemblies included in the products
of the Company are obtained from a single supplier or a limited group of
suppliers. The Company's key suppliers include Bullen Ultrasonics, Inc., which
supplies electrodes, Edwards High Vacuum Inc., Lam's supplier of chillers, and
Advanced Energy Industries, Lam's RF generator supplier. The Company purchases
in excess of $500,000 of supplies on a monthly basis from these 




                                       15
<PAGE>   16
 suppliers. Each of these suppliers has a one year blanket purchase contract
under which Lam may issue purchase orders. These contracts may be renewed
periodically. Each of these suppliers has sold products to Lam during at least
the last four years, and there is no reason to expect that these contracts will
not continue to be renewed in the future or otherwise replaced with competent
alternative source suppliers. Management believes that alternative sources could
be obtained and qualified to supply these products. Nevertheless, a prolonged
inability to obtain certain components could have an adverse effect on the
Company's operating results and could result in damage to customer
relationships.

           Highly Competitive Industry

           The semiconductor equipment manufacturing industry is highly
competitive. The Company expects to continue to face substantial competition
throughout the world. A substantial investment is required by semiconductor
manufacturers to install and integrate capital equipment into a semiconductor
production line. The Company believes that as a result, once a semiconductor
manufacturer has selected a particular supplier's capital equipment, the
manufacturer generally relies upon that equipment for the specific production
line application and frequently will attempt to consolidate its other capital
equipment requirements with the same supplier. Accordingly, Lam would expect to
experience difficulty in selling to a given customer if that customer had
initially selected or selects a competitor's capital equipment. The Company
believes that to remain competitive, significant financial resources are
required in order to offer a broad range of products, to maintain customer
service and support centers worldwide, and to invest in product and process R&D.

           The semiconductor equipment industry is becoming increasingly
dominated by large manufacturers who have the resources to support customers on
a worldwide basis, and certain of Lam's competitors have substantially greater
financial resources and more extensive engineering, manufacturing, marketing and
customer service and support. In addition, there are smaller, emerging
semiconductor equipment companies that provide innovative technology that may
have performance advantages over systems offered by the Company.

           Competitors are expected 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
competitors enter into strategic relationships with leading semiconductor
manufacturers covering products similar to those sold or being developed by the
Company, its ability to sell products to those manufacturers could be adversely
affected. No assurance can be given that Lam will continue to compete
successfully in the United States or worldwide.

           Present or future competitors may be able to develop products
comparable or superior to those offered by the Company or adapt more quickly to
new technologies or evolving customer requirements. In particular, while Lam
currently is developing additional product enhancements that it believes
addresses customer requirements, there can be no assurance that the development
or introduction of these additional product enhancements will be successfully
completed, at all or on a timely basis, or that these product enhancements will



                                       16
<PAGE>   17

achieve market acceptance or be competitive. Accordingly, there can be no
assurance that the Company will be able to continue to compete effectively in
its markets, that competition will not intensify or that future competition will
not have a material adverse effect on the business, operating results, financial
condition and cash flows of the Company.

           International Sales

           International sales accounted for 42% and 51%, respectively, of net
revenues for the first quarter of fiscal 1999 and 1998, and 55%, 57% and 63%,
respectively, of net revenues for fiscal years 1998, 1997 and 1996.
Historically, sales to the Asia regions have accounted for a substantial portion
of international sales. Recent banking and currency problems in the Asia regions
have had and will continue to have a significant adverse impact on the Company's
revenue and operations, including specifically revenues and operations for
fiscal 1999.

           Sales of products currently are denominated in United States dollars.
In Korea, devaluation of the Won and difficulties by customers in obtaining
credit have curtailed semiconductor equipment investment and have led to
cancellation or delay of orders by the Company's customers, and are likely to
continue to do so in fiscal 1999.

           In Japan, the Company's sales are denominated in Japanese Yen. A
weakening of the value of the Japanese Yen as compared to the U.S. dollar could
negatively impact operating margins. Currently, the Company enters into foreign
currency forward contracts to minimize the impact of exchange rate fluctuations
on yen-denominated assets and liabilities and will continue to enter into such
hedging transactions in the future.

           In Europe, sales following January 1, 1999 will be subject to certain
provisions governing the transition of commercial transactions to the Euro. Lam
expects to be able to meet related legal requirements by January 1, 1999, and
through the transition period. The Company does not currently expect that
introduction and use of the Euro will materially affect its foreign exchange and
hedging activities or will result in any material increase in transaction costs.
Lam will continue to evaluate the impact over time of the introduction of the
Euro. Based on currently available information management does not believe that
the introduction of the Euro will have a material adverse impact on Lam's
financial condition or the overall trends in results of operations.

           The impact of these and other factors on the Company's revenues and
operating results in any future period is difficult to forecast. There can be no
assurance that these and other factors relating to international sales and
operations by the Company will not materially adversely affect future business
and financial results, or in ways not readily foreseeable.

           Potential Volatility of Common Stock Price

           The market price for Lam Common Stock has been volatile and it could
continue to be subject to significant fluctuations in response to market or
industry conditions generally, or specific variations in quarterly operating
results, shortfalls in revenues or earnings from levels expected by securities
analysts and other factors such as announcements of restructurings,
technological innovations, reductions in force, departure of key employees,
consolidations of operations or introduction of new products by the Company or
by the Company's competitors, government regulations, developments in patent or
other proprietary rights, disruptions with key customers or the occurrence of
political, economic or environmental events globally or in key sales regions. In
addition, the stock market has in recent years experienced significant price
fluctuations. These fluctuations often have been unrelated to the operating
performance of the specific companies whose stocks are traded. Recent
fluctuations affecting Lam Common Stock have been tied in part to the Asian and
Russian financial crisis and the price of and market for semiconductors. Broad
market fluctuations, as well as economic conditions generally in the
semiconductor industry, may adversely affect the market price of Lam Common
Stock.

           Intellectual Property Matters

           From time to time, Lam has received notices from third parties
alleging infringement of such parties' patent or other intellectual property
rights by the Company's products. In such cases, it is the policy of the Company
to defend the claims or negotiate licenses on commercially reasonable terms,
where considered appropriate. However, no assurance can be given that Lam will
be able in the future to negotiate necessary licenses on commercially reasonable
terms, or at all, or that any litigation resulting from such claims would not
have a material adverse effect on the Company's business and financial results.

           In October 1993, Varian brought suit against Lam in the United States
District Court for the Northern District of California, seeking monetary damages
and injunctive relief based on the Company's alleged infringement of certain
patents held by Varian. The Company has asserted defenses of invalidity and
unenforceability of the patents that are the subject of the lawsuit, as well as
non-infringement of such patents by the Company's products. No trial date is
currently scheduled. While litigation is subject to inherent uncertainties and
no assurance can be given that Lam 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 operating results or the Company's financial position.

           The Company's success depends in part on its proprietary technology.
While Lam attempts to protect its proprietary technology through patents,
copyrights and trade secret protection, it believes that its success will depend
on more technological expertise, continuing the development of new systems,
market penetration and growth of its installed base and the ability to provide
comprehensive support and service to customers. There can be no assurance that
the Company will be able to protect its technology or that competitors will not
be able to develop similar or more competitive technology independently. Lam
currently holds a number of United States and foreign patents and patent
applications pending. There can be no 



                                       18
<PAGE>   19

assurance that any patents issued to the Company will not be challenged,
invalidated or circumvented, that pending applications will be issued or that
the rights granted or anticipated thereunder will provide competitive
advantages.

           Year 2000 Compliance

           See discussion in Management Discussion and Analysis of Financial
Condition and Results of Operation on page 11 to 13.

           Restructurings and Consolidation of Operations

           The Company substantially restructured and consolidated its
operations during the quarters ended March 31, 1998 and June 30, 1998.
Implementation of these restructurings and consolidations involves several
risks, including that of simplifying and modifying its product line offerings
(which will increase its dependence on fewer products and potentially reduce
overall sales).

           Although the Company believes that the actions it is taking and
contemplates taking in connection with the restructurings and consolidations,
including the reduction in workforce, the consolidation of manufacturing
operations and the exiting from FPD and CVD operations, should help more closely
align Lam with its business outlook, there can be no assurance that such actions
will enable the Company to achieve its objectives of reducing costs, or can be
accomplished at specific or optimum values or on time or as intended. In
addition, there can be no assurance that the size of the restructuring charge
will not exceed current estimates. The Company's future consolidated operating
results and financial condition could be adversely affected should it encounter
difficulty in effectively managing the restructurings and consolidations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

           For financial market risks related to changes in interest rates and
foreign currency exchange rates, refer to Part II, Item 7A, Quantitative and
Qualitative Disclosures About Market Risk, in the Company's Annual Report on
Form 10-K for the year ended June 30, 1998.

PART II. OTHER INFORMATION

ITEM 1.    Legal Proceedings

           In October 1993, Varian brought suit against the Company in the
United States District Court for the Northern District of California, seeking
monetary damages and injunctive relief based on the Company's alleged
infringement of certain patents held by Varian. The Company has asserted
defenses of invalidity and unenforceability of the patents that are the subject
of the lawsuit, as well as non-infringement of such patents by the Company's
products. No trial date is currently scheduled. While litigation is subject to
inherent uncertainties and no assurance can be given that Lam 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 




                                       19
<PAGE>   20

Company believes that the Varian lawsuit will not have a material adverse effect
on the Company's operating results or the Company's financial position.

           In addition, the Company is from time to time notified by various
parties that its products 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 flow statements.

                          the relevant Margin Period is less than 0.10, 0.75
                          percent per annum;

                  (iii)   if the Guarantor has net profits of greater than
                          US$1, as determined in accordance with generally
                          accepted accounting principles and practices in the
                          United States of America as consistently applied,
                          during both the fiscal quarter ending on September
                          26, 1999 and the fiscal quarter ending on December
                          26, 1999 and the Senior Indebtedness Ratio of the
                          Guarantor as set forth in the quarterly financial
                          statements and information of the Guarantor for the
                          fiscal quarter ending immediately preceding the first

                          as determined in accordance with generally accepted
                          accounting principles and practices in the United
                          States of America as consistently applied, during both
                          the fiscal quarter ending on September 26, 1999 and
                          the fiscal quarter ending on December 26, 1999 and the
                          Senior Indebtedness Ratio of the Guarantor as set
                          forth in the quarterly financial statements and
                          information of the Guarantor for the fiscal quarter
                          ending immediately preceding the first day of the
                          relevant Margin Period is greater than or equal to
                          0.15, 0.95 percent per annum.

         (c)      Notwithstanding the provisions of Clause 5.3(b), if the
                  Guarantor fails to deliver to the Agent the financial
                  statements and information required under clause (i) and (ii)
                  of Subparagraphs 4(a) of the Guaranty within the time periods
                  set forth therein, the Margin shall be, in respect of any
                  period from and including the fifteenth day following the date
                  of such failure to and including the fifteenth day following
                  receipt by the Agent of such financial statements and
                  information (at which time subclause (b) above shall apply),
                  0.95 percent per annum.

         Except where item (i) of subclause (b) above shall be applicable, the
         Borrower shall notify the Agent of the Senior Indebtedness Ratio of the
         Guarantor 


                                       12
<PAGE>   19
         applicable to each Margin Period and shall submit Margin Certificates
         (duly completed and signed by a duly authorized officer of the
         Guarantor), and supporting evidence in respect thereof on or before the
         first day of such Margin Period.

5.4      Selection of Interest Periods

         Before the beginning of the initial Interest Period (which shall
         commence on the date that is one month after the Drawdown Date) with
         respect to the Loan, the Borrower may by notice received by the Agent
         not later than 10 a.m. (Tokyo time) on the fifth Banking Day prior to
         the first day of the initial Interest Period and subject to Clause 5.5
         specify whether that Interest Period shall have a duration of one, two,
         three or six months. The Borrower may, subject to Clause 5.5, select
         subsequent Interest Periods with respect to the Loan. Before the
         beginning of each subsequent Interest Period, the Borrower may by
         notice received by the Agent not later than 10 a.m. (Tokyo time) on the
         fifth Banking Day prior to the first day of such subsequent Interest
         Period and subject to Clause 5.5 specify whether that Interest Period
         shall have a duration of one, two, three or six months.

5.5      Determination of Interest Periods

         Each Interest Period shall be of the duration specified by the Borrower
         pursuant to Clause 5.4 except that:

         (a)      the initial Interest Period in respect of the Loan will
                  commence on the Drawdown Date and each subsequent Interest
                  Period in respect of the Loan will commence on the last day of
                  the previous Interest Period for the Loan;

         (b)      any Interest Period that would otherwise overrun the Maturity
                  Date shall end on the Maturity Date;

         (c)      the Borrower may choose an Interest Period of less than one
                  month in order that the Interest Period may end on a Principal
                  Payment Date;


                                       13
<PAGE>   20
         (d)      the Borrower may not choose an Interest Period if as a result
                  thereof the Borrower would be unable to make the payment due
                  on the next Principal Payment Date on a day which is an
                  Interest Payment Date; and

         (e)      if the Borrower fails to specify the duration of an Interest
                  Period in accordance with the provisions of Clause 5.4 and
                  this Clause 5.5, that Interest Period shall have a duration of
                  one month or such other period as shall comply with this
                  Clause 5.5.

5.6      Notification of Interest Periods and interest rate

         The Agent shall notify the Borrower and the Lenders promptly of the
         duration of each Interest Period or other period for the calculation of
         interest (or, as the case may be, default interest) and of each rate of
         interest determined by it under this Clause 5.

5.7      Market disruption; non-availability

         (a)      If and whenever, at any time prior to the making or
                  continuation of the Advance:

                  (i)     the Agent shall have determined (which determination
                          shall, in the absence of manifest error, be
                          conclusive), that adequate and fair means do not
                          exist for ascertaining TIBOR in respect of any
                          Interest Period in accordance with this Agreement; or

                  (ii)    the Agent shall have received notification from
                          Lenders with Contributions aggregating not less than
                          one-third of the total of the Loan (or, if no Advance
                          has been made, Commitments aggregating not less than
                          one third of the Commitments of all the Lenders) that
                          deposits in Yen are not available to those Lenders in
                          the relevant interbank market in the ordinary course
                          of business in sufficient amounts to fund (or
                          maintain) their Contributions to the Loan or that
                          their funding costs in respect of the Loan are not
                          accurately reflected by TIBOR having regard to the
                          likely interest rate in respect of such Interest
                          Period,


                                       14
<PAGE>   21
                  the Agent shall immediately give notice (a "Determination
                  Notice") of that fact to the Borrower and to each of the
                  Lenders. A Determination Notice shall give particulars of the
                  relevant circumstances giving rise to its issue.

         (b)      After the Interest Period in which any Determination Notice
                  falls, the Loan shall bear interest at the rate per annum
                  determined by the Agent to be the aggregate of (i) the
                  applicable Margin and (ii) the rate, expressed as a decimal,
                  equal to the cost to each Lender (as certified by it, which
                  certification shall be binding upon the parties hereto in the
                  absence of manifest error, and expressed as a rate per annum)
                  of funding its Contribution in Tokyo and in Yen during such
                  period in the Tokyo interbank market on each day during the
                  relevant period. The Borrower shall pay such interest on the
                  Loan on a monthly basis. The provisions of Clause 5.5 shall
                  apply mutatis mutandis as if the Borrower has chosen a
                  duration of one month for any Interest Period. If the Agent
                  deems that the relevant circumstances stated in such
                  Determination Notice have ceased to exist, the parties hereto
                  agree to return to the TIBOR based pricing as soon as
                  reasonably practicable.

5.8      Fixed rate option

         On the effective date of the initial assignment by the initial Lender
         hereunder of all or any of its rights hereunder to a Substitute
         pursuant to Clause 15.4 (the "Conversion Date"), the parties hereto
         shall convert the interest rate payable by the Borrower hereunder to a
         fixed rate. Not later than five Banking Days prior to the Conversion
         Date (which shall be the last day of an Interest Period), the Agent
         will provide the Borrower with a quotation of the fixed interest rate
         at which the initial Lender and such Substitute are prepared to
         continue to maintain the Loan for the remaining term up to the Maturity
         Date. If such quotation is acceptable to the Borrower, the Borrower
         will notify the Agent of its intention to convert the Loan from a
         floating rate loan to a fixed rate loan on or before 10:00 a.m. (Tokyo
         time) on the fourth Banking Day prior to the Conversion Date, in which
         case the Loan shall, commencing on the Conversion Date, bear interest
         at the fixed rate quoted as aforesaid. Interest shall be calculated on
         the basis of the actual number of days elapsed and a year of 365 days
         and shall be payable on each 


                                       15
<PAGE>   22
         Fixed Rate Payment Date for the Fixed Rate Period then ending. "Fixed
         Rate Payment Date" means the date which (save as mentioned below) falls
         three months after the last preceding Fixed Rate Payment Date or, in
         the case of the first Fixed Rate Payment Date, after the Conversion
         Date, provided that (x) on the first and the second Principal Payment
         Dates, any interest accrued up to each such date on the amount of the
         principal of the Loan due on such date shall be payable and (y) the
         last Fixed Rate Payment Date shall be the Maturity Date. If any Fixed
         Rate Payment Date falls on a day which is not a Banking Day, any
         payment due on such date shall be made on the immediately succeeding
         Banking Day (unless such succeeding Banking Day falls in the next
         calendar month, in which case (i) such Fixed Rate Payment Date shall be
         the immediately preceding Banking Day, and (ii) each subsequent Fixed
         Rate Payment Date shall be the last Banking Day of the third month
         after the month in which the preceding Fixed Rate Payment Date shall
         have fallen). "Fixed Rate Period" means the period commencing on and
         including the Conversion Date and ending on and including the first
         Fixed Rate Payment Date, and thereafter each successive period
         commencing on and including the date immediately following the last
         preceding Fixed Rate Payment Date and ending on and including the next
         succeeding Fixed Rate Payment Date. During the existence of a Default
         the Borrower shall pay interest (both before and after judgment) on (a)
         the outstanding Loan and (b) on any amount (other than principal of the
         outstanding Loan) not paid when due at a rate per annum equal to the
         applicable fixed rate plus two percent. If the fixed rate quotation
         provided by the Agent is not acceptable to the Borrower, the Borrower
         shall repay the Loan in full on the proposed Conversion Date.

6.       REPAYMENT, PREPAYMENT AND CANCELLATION

6.1      Repayment

         The Loan shall be repaid in three installments payable on September 30,
         1999, September 30, 2000 and the Maturity Date (each such date, a
         "Principal Payment Date") as follows:

                  September 30, 1999                   (Y)425,000,000
                  September 30, 2000                   (Y)425,000,000
                  Maturity Date                        (Y)850,000,000


                                       16
<PAGE>   23
6.2      Voluntary prepayment

         The Borrower may voluntarily prepay the Loan subject to the provisions
         of this Clause 6 and of Clause 12.1. Any voluntary prepayment of the
         Loan when it then bears interest at one of the rates specified in
         Clause 5.1 may be in whole or in part, with any partial prepayment to
         be in a minimum of (Y)100,000,000 (one hundred million Yen) or a larger
         sum which is an integral multiple of (Y)100,000,000 (one hundred
         million Yen). Any voluntary prepayment of the Loan when it then bears
         interest at a fixed rate pursuant to Clause 5.8 may be in whole only.

6.3      Additional voluntary prepayment

         The Borrower may also prepay (in whole but not in part only), without
         premium or penalty, but without prejudice to its obligations under
         Clause 8.8, Clause 12.1 or Clause 13.2, the Contribution of any Lender
         to which the Borrower has become obliged to pay additional amounts
         under Clause 8.8 or Clause 13.2. On notice of such a prepayment being
         given, the Commitment of the relevant Lender shall be reduced to zero.

6.4      Timing, amounts and application of prepayments

         Prepayments made on a date other than an Interest Payment Date will be
         subject to, inter alia, the provisions of Clause 12.1(c) and (d).
         Prepayments under this Agreement shall be made together with: (a)
         accrued interest to the date of prepayment; (b) any additional amount
         payable under Clause 8.8 or Clause 13.2; and (c) all other sums payable
         by the Borrower to the relevant Lender under this Agreement and any
         amounts payable under Clause 12.1.

6.5      Notice and effect of prepayment

         No prepayment may be effected under this Clause 6 unless the Borrower
         shall have given the Agent at least 10 days' notice of its intention to
         make such prepayment. Every notice of prepayment shall be effective
         only on actual receipt by the Agent, shall be irrevocable and shall
         oblige the Borrower to make such prepayment on the date specified in
         the notice. On a prepayment being made, 


                                       17
<PAGE>   24
         the Commitments shall be automatically reduced by an amount equal to
         the amount so prepaid and sums prepaid may not be re-borrowed. Any such
         prepayment shall be applied to the then outstanding repayment
         installments of the principal of the Loan as set out in Clause 6.1 in
         the inverse order of their maturity.

7.       FEES AND EXPENSES

7.1      Fees

         The Borrower shall pay to the Agent whether or not any part of the
         Commitments is ever advanced an arrangement fee, in the amount and at
         the time agreed between the Borrower and the Arranger in a letter dated
         on or around the date hereof.

7.2      Expenses

         The Borrower shall pay to the Agent:

                  of the Agent's invoice therefor, all reasonable expenses
                  (including legal and out-of-pocket expenses) incurred by the
                  Agent and the Arranger in connection with the negotiation,
                  preparation, syndication, execution and delivery of this
                  Agreement whether or not any part of the Commitments is ever
                  advanced;

         (b)      as soon as reasonably practicable in accordance with the
                  Borrower's customary procedures for reviewing and processing
                  such items, and in any event within 30 days following receipt
                  of the Agent's invoice therefor, all reasonable expenses
                  (including legal and out-of-pocket expenses) incurred by the
                  Agent and the Arranger in connection with any amendment or
                  extension of or the granting of any waiver or consent under
                  this Agreement; and


                                       18
<PAGE>   25
         (c)      on demand, all reasonable expenses (including legal and
                  out-of-pocket expenses) incurred by the Agent, the Arranger,
                  the Lenders or any of them in contemplation of, or otherwise
                  in connection with, the enforcement of, or preservation of any
                  rights under, this Agreement, or otherwise in respect of the
                  moneys owing under this Agreement, together with interest at
                  the rate referred to in Clause 5.2 from the date on which such
                  expenses were incurred to the date of payment (as well after
                  as before judgment).

7.3      Consumption, etc. tax

         All fees and expenses payable pursuant to this Clause 7 shall be paid
         together with an amount equal to any consumption, sales, value added or
         similar tax payable by the Agent, the Arranger or any Lender in respect
         of those fees and expenses.

7.4      Stamp and other duties

         The Borrower shall pay all stamp, documentary, registration or other
         like duties or taxes (including any duties or taxes payable by the
         Lenders) imposed on or in connection with this Agreement and shall
         indemnify the Agent, the Arranger and the Lenders against any liability
         arising by reason of any delay or omission by the Borrower to pay such
         duties or taxes.

8.       PAYMENTS AND TAXES; ACCOUNTS AND CALCULATIONS

8.1      No set-off or counterclaim; distribution to the Lenders

         The Borrower acknowledges that, in performing their obligations under
         this Agreement, the Lenders will be incurring liabilities to third
         parties in relation to the funding of amounts advanced to the Borrower,
         those liabilities matching the liabilities of the Borrower to the
         Lenders, and that it is reasonable for the Lenders to be entitled to
         receive payments from the Borrower gross on their due date in order
         that the Lenders are put in a position to perform their matching
         obligations to the relevant third parties. Accordingly all payments to
         be made by the Borrower under this Agreement shall be made in full,
         without any set-off or counterclaim whatsoever and, subject to Clause
         8.8, free and clear of any deductions or withholdings, in Yen (except
         for costs, charges or expenses which 


                                       19
<PAGE>   26
         shall be payable in the currency in which they are incurred) on their
         due date to the account of the Agent specified in Schedule 1 or such
         other bank and/or account as the Agent may from time to time specify
         for this purpose. Except where this Agreement specifically provides for
         a payment to be made for the account of a particular Lender, the Agent
         or the Arranger, payments to be made by the Borrower under this
         Agreement shall be for the account of all the Lenders and the Agent
         shall forthwith distribute those payments in like funds as are received
         by the Agent to the Lenders ratably in accordance with their
         Commitments or Contributions, as the case may be.

8.2      Payments by the Lenders

         Sums to be advanced by the Lenders to the Borrower under this Agreement
         shall be remitted in Yen on the Drawdown Date to the account of the
         Agent at such bank as the Agent may have notified to the Lenders and
         shall be paid by the Agent on that date in like funds as are received
         by the Agent to the Borrower's Account.

8.3      Agent may assume receipt

         Where any sum is to be paid under this Agreement to the Agent for the
         account of the Borrower or any Lender, the Agent may assume that the
         payment will be made when due and may (but shall not be obliged to)
         make that sum available to the person so entitled. If that payment is
         then not made to the Agent, then the person to whom that sum was made
         available shall on request refund that sum to the Agent together with
         interest on it sufficient to compensate the Agent for the cost of
         making the sum available up to the date of repayment and the person by
         whom the sum was payable shall indemnify the Agent for all loss or
         expense which the Agent may sustain or incur as a consequence of that
         sum not having been paid on its due date.

8.4      Time of payment

         Any sum payable by the Borrower to the Agent, the Arranger or to any
         Lender under this Agreement shall be paid so as to be received in
         immediately available funds in the payee's designated account by 11:00
         a.m. (Tokyo time) for that 


                                       20
<PAGE>   27
         account. Any payment received by the Agent from the Borrower for the
         account of the Arranger or any Lender or Lenders which is received on
         its due date but after the time specified above and too late to be made
         available on that due date to the Arranger or the relevant Lender or
         Lenders, as appropriate, shall be deemed to be received on the next
         Banking Day (though the Agent shall give credit to the Borrower for any
         interest earned by the Agent on that sum prior to its distribution). In
         holding any such sum, the Agent shall not be acting as agent of or
         trustee for the Borrower and may invest, deposit or otherwise deal with
         that sum as it may, in its absolute discretion, see fit without any
         duty or obligation to the Borrower in respect of that sum other than as
         specifically provided for in this Agreement.

8.5      Non-Banking Days

         When any payment under this Agreement would otherwise be due on a day
         which is not a Banking Day, the due date for payment shall be extended
         to the next following Banking Day unless that Banking Day falls in the
         next calendar month in which case payment shall be made on the
         immediately preceding Banking Day.

8.6      Calculations

         Except with respect to interest on the Loan and unless provided
         otherwise, all interest and other payments of an annual nature under
         this Agreement shall accrue from day to day and be calculated on the
         basis of actual days elapsed and a 365 day year. Interest on the Loan
         shall accrue from day to day and be calculated on the basis of actual
         days elapsed and a 360 day year.

8.7      Certificates conclusive

         Any certificate or determination of the Agent or any Lender as to any
         rate of interest or any amount payable under this Agreement shall, in
         the absence of manifest error and so long as it acts in good faith, be
         conclusive and binding on the Borrower and (in the case of a
         certificate or determination by the Agent) on the Lenders; provided
         that, in the case of expenses required to be paid by the Borrower
         pursuant to Clause 7.2, the Agent, the Arranger, or any Lender, as the
         case may be, shall provide such invoices, receipts or other documents
         evidencing 


                                       21
<PAGE>   28
         or supporting such determination as is reasonably available to it, and
         such evidence or support shall be prima facie evidence of the amount
         payable by the Borrower pursuant to Clause 7.2.

8.8      Grossing-up for Taxes

         If at any time the Borrower is required to make any deduction or
         withholding in respect of taxes, duties, assessments or governmental
         charges of whatsoever nature ("Taxes") from any payment due under this
         Agreement for the account of any Lender, the Arranger or the Agent (or
         if the Agent is required to make any such deduction or withholding from
         a payment to the Arranger or a Lender), the sum due from the Borrower
         in respect of such payment shall be increased to the extent necessary
         to ensure that, after the making of such deduction or withholding, each
         Lender, the Arranger and the Agent receives on the due date for such
         payment (and retains, free from any liability in respect of such
         deduction or withholding) a net sum equal to the sum which it would
         have received had no such deduction or withholding been required to be
         made and the Borrower shall indemnify each Lender, the Arranger and the
         Agent against any losses or costs incurred by any of them by reason of
         any failure of the Borrower to make any such deduction or withholding
         or by reason of any increased payment not being made on the due date
         for such payment. The Borrower shall promptly deliver to the Agent any
         receipts, certificates or other proof evidencing the amounts (if any)
         paid or payable in respect of any deduction or withholding as
         aforesaid.

8.9      Lender accounts

         Each Lender shall maintain, in accordance with its usual practices, an
         account or accounts evidencing the amounts from time to time lent by,
         owing to and paid to it under this Agreement. The Agent shall maintain
         a control account showing the Loan and other sums owing by the Borrower
         under this Agreement and all payments in respect thereof made by the
         Borrower from time to time. The control account shall, in the absence
         of manifest error, be conclusive as to the amount from time to time
         owing by the Borrower under this Agreement.

8.10     Partial payments

         If, on any date on which a payment is due to be made by the Borrower
         under this Agreement, the amount received by the Agent from the
         Borrower falls short of the total amount of the payment due to be made
         by the Borrower on that date then, without prejudice to any rights or
         remedies available to the Agent, the Arranger or the Lenders under this
         Agreement, the Agent shall apply the amount actually received from the
         Borrower in or towards discharge of the obligations of the Borrower
         under this Agreement in the following order, notwithstanding any
         appropriation made, or purported to be made, by the Borrower:

         (a)      firstly, in or towards payment of any unpaid fees, costs and
                  expenses of the Agent under this Agreement;

         (b)      secondly, in or towards payment to the Arranger of any portion
                  of the arrangement fee payable under Clause 7.1 which remains
                  unpaid;

         (c)      thirdly, in or towards payment of any default interest which
                  is due but remains unpaid;

         (d)      fourthly, in or towards payment to the Lenders, on a pro rata
                  basis, of any accrued interest (other than default interest)
                  which is due but remains unpaid;

         (e)      fifthly, in or towards payment to the Lenders, on a pro rata
                  basis, of any principal which is due but remains unpaid; and

         (f)      sixthly, in or towards payment of any other sum which is due
                  but remains unpaid (and, if more than one such sum so remains
                  unpaid, on a pro rata basis).

8.11     Variation of application

         The order of application set out in Clause 8.10(c) - 8.10(f) may be
         varied by the Agent only if all the Lenders so direct.

                  this Agreement and of any Default immediately on becoming
                  aware of it and will from time to time, if so requested by the
                  Agent, confirm to the Agent that, except as otherwise stated
                  in that confirmation, no Default has occurred and is
                  continuing;

         (b)      Use of proceeds

                  ensure that its obligations under this Agreement shall,

                  (in a form reasonably acceptable to the Agent) in respect of
                  each quarter in accordance with generally accepted accounting
                  principles and practices in the United States of America


                                       27

                  to the Agent for distribution to all the Lenders as soon as
                  practicable but not later than 100 days (in the case of the
                  annual financial statements) or 50 days (in the case of
                  quarterly financial statements) after the end of the financial
                  period to which they relate;

         (e)      Delivery of reports, etc.

                  deliver to the Agent, for distribution to the Lenders,

                  circular, notice or like document issued by the Borrower to
                  its creditors generally, at the time of issue thereof, and
                  provide the Agent with such other information relating to the
                  Borrower and the Guarantor as any Lender (through the Agent)
                  may reasonably request from time to time;

         (f)      Pension schemes

                  ensure that the levels of contribution to the pension schemes
                  for the time being operated by the Borrower are and continue
                  to be sufficient to cover the liabilities of such schemes in
                  full to the extent contributions to cover such liabilities are
                  permitted or will not result in taxation on participants

         acting on the instructions of the Majority Lenders, it will not create,
         incur, assume or suffer to exist any Lien upon or with respect to any
         of its properties, revenues or assets, 


                                       28

                  respect when made or deemed to be made and such incorrectness
                  or misleadingness shall not be cured within 30 days after
                  written notice thereof is given by the Agent to the Borrower;

                  under this Agreement (other than failure to pay any sum when
                  due) and, in respect of any such breach or omission which in
                  the opinion of the Majority Lenders is capable of remedy, such
                  breach or omission shall continue for 30 or more days after
                  the occurrence of such default; or the Guarantor commits any
                  breach of or omits to observe any of the obligations or
                  undertakings expressed to be assumed by it under the Guaranty

                  opinion of the Majority Lenders is capable of

                  agreement under which such indebtedness was created; or (ii)
                  defaults in the observance or performance of any other
                  agreement or condition relating to any such indebtedness or
                  contained in any instrument or agreement evidencing, securing
                  or relating thereto, the effect of which is to cause, or to
                  permit the holder or holders of such indebtedness (or trustee
                  or agent on behalf of such holder or holders) to cause, with
                  the giving of notice if required, such indebtedness to become
                  due prior to its stated maturity and any such default shall

                  (v)     the Borrower or the Guarantor takes any action in
                          furtherance of, or indicating its consent to, approval
                          of, or acquiescence in, any of the acts set forth in

         (a)      the obligation of each Lender to make its Commitment available
                  shall be terminated and the Commitments shall then immediately
                  be reduced to zero; and/or

         (b)      the outstanding Loan and all interest accrued and all other
                  sums payable under this Agreement have become immediately due

                  whereupon the same shall, immediately or in accordance with
                  the terms of that notice, become so due and payable;

         provided that, upon the occurrence of any Event of Default described in
         Clause 11.1(e), the result which would otherwise occur only upon
         declaration by the Agent shall occur automatically, without the
         necessity of any action by the Agent or the Lenders.


                                       32
<PAGE>   39
         On or at any time after the making of any such declaration, the Agent

         prejudice to Clause 5.2), to select the duration of Interest Periods.

         notice to the Borrower (a) call for repayment of the Loan on such date
         as may be specified in that notice and the Loan shall become due and
         payable on the date so specified together with all interest accrued and
         all other sums payable under this Agreement or (b) withdraw that
         declaration with effect from the date specified in the notice.

12.      INDEMNITIES

12.1     Broken funding and other indemnities

         The Borrower shall on demand indemnify each Lender, the Arranger and
         the Agent, without prejudice to any of their other respective rights
         under this Agreement, against any loss or expense which such Lender,
         the Arranger or the Agent shall certify (which certification shall be
         provided in writing within six months after such Lender, the Arranger
         or the Agent determines that such indemnification is due) as having
         been sustained or incurred by it as a consequence of:

         (a)      any default in payment by the Borrower of any sum under this
                  Agreement when due;

         (b)      the occurrence of any other Event of Default or any
                  acceleration pursuant to Clause 11.2;

         (c)      any prepayment of the Advance or part thereof when it then
                  bears interest at one of the rates specified in Clause 5.1
                  being made under Clause 6.2, Clause 6.3 or Clause 13.1
                  otherwise than on an Interest Payment Date;


                                       33
<PAGE>   40
         (d)      any prepayment of the Advance when it then bears interest at a
                  fixed rate pursuant to Clause 5.8 being made under Clause 6.2,
                  Clause 6.3 or Clause 13.1 at any time (whether on an Interest
                  Payment Date or otherwise); or

         (e)      the Advance not being made for any reason (excluding any
                  default by the Agent, the Arranger or any Lender) on the
                  Drawdown Date,

         including, in any such case, any loss or expense sustained or incurred
         by such Lender in maintaining or funding its Contribution or any part
         thereof or in liquidating or re-employing deposits from third parties
         acquired or contracted for to fund its Contribution or any part thereof
         or any other amount owing to such Lender.

12.2     Currency indemnity

         If any sum due from the Borrower under this Agreement 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 under this
         Agreement 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 the Borrower, (b) obtaining an order or judgment in any
         court or other tribunal or (c) enforcing any order or judgment given or
         made in relation to this Agreement, the Borrower shall indemnify and
         hold harmless the Agent, the Arranger and each Lender from and against
         any loss suffered as a result of any difference between (i) the rate of
         exchange used for such purpose to convert the sum in question from the
         first currency into the second currency and (ii) the rate or rates of
         exchange at which the Agent, the Arranger or such Lender may 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. Any amount due
         from the Borrower under this Clause 12.2 shall be due as a separate
         debt and shall not be affected by judgment being obtained for any other
         sums due under or in respect of this Agreement and the term "rate of
         exchange" includes any premium and costs of exchange payable in
         connection with the purchase of the first currency with the second
         currency.

13.      UNLAWFULNESS AND INCREASED COSTS

13.1     Illegality

         If, after the date of this Agreement, the adoption of any Governmental
         Rule, any change in any Governmental Rule or the application or
         requirements thereof (whether such change occurs in accordance with the
         terms of such Governmental Rule as enacted, as a result of amendment or
         otherwise), any change in the interpretation or administration of any
         Governmental Rule by any Governmental Authority, or compliance by any
         Lender with any request or directive (whether or not having the force
         of law) of any Governmental Authority (a "Change of Law") shall make it
         unlawful or impossible for any Lender to make or maintain its
         Contribution, such Lender shall immediately notify Agent and Borrower
         of such Change of Law and the Borrower shall, not later than the date
         specified by such Lender, repay such Lender's Contribution.

13.2     Increased costs

         If, after the date of this Agreement, any Change of Law:

                           (a) Shall subject any Lender to any tax, duty or
                  other charge with respect to its Contribution or shall change
                  the basis of taxation of payments by the Borrower to any
                  Lender on its Contribution or in respect to such Contribution
                  under this Agreement (except for changes in the rate of
                  taxation on the overall net income of any Lender imposed by
                  its jurisdiction of incorporation or the jurisdiction in which
                  its principal executive office is located); or

                           (ii) Shall impose, modify or hold applicable any
                  reserve (excluding any Reserve Requirement or other reserve to
                  the extent included in the calculation of TIBOR for the Loan),
                  special deposit or similar requirement against assets held by,
                  deposits or other liabilities in or for the account of,
                  advances or loans by, or any other acquisition of funds by any
                  Lender for its Contribution; or


                                       35
<PAGE>   42
                           (iii) Shall impose on any Lender any other condition
                  related to its Contribution, the Loan or such Lender's
                  Commitment;

         And the effect of any of the foregoing is to increase the cost to such
         Lender of making, renewing, or maintaining its Contribution, the Loan
         or its Commitment or to reduce any amount receivable by such Lender
         hereunder; then the Borrower shall from time to time, within five (5)
         days after demand by such Lender, pay to such Lender additional amounts
         sufficient to reimburse such Lender for such increased costs or to
         compensate such Lender for such reduced amounts. A certificate as to
         the amount of such increased costs or reduced amounts, submitted by
         such Lender to the Borrower shall, in the absence of manifest error, be
         conclusive and binding on the Borrower for all purposes. The
         obligations of the Borrower under this Clause 13.2 shall survive the
         payment and performance of the Borrower's obligations under this
         Agreement and the termination of this Agreement; provided, however,
         that any Lender must submit a demand for payment pursuant to this
         provision within six (6) months after such Lender has first
         conclusively determined that such reimbursement or compensation is due
         such Lender under this and similar agreements.

13.3     Capital requirements

         If, after the date of this Agreement, any Lender determines that (i)
         any Change of Law affects the amount of capital required or expected to
         be maintained by such Lender or any party controlling such Lender (a
         "Capital Adequacy Requirement") and (ii) the amount of capital
         maintained by such Lender or such party which is attributable to or
         based upon such Lender's Contribution, the Loan or such Lender's
         Commitments or this Agreement must be increased as a result of such
         Capital Adequacy Requirement (taking into account such Lender's or such
         party's policies with respect to capital adequacy), the Borrower shall
         pay to such Lender or such party, within five (5) days after demand of
         such Lender, such amounts as such Lender or such party shall determine
         are necessary to compensate such Lender or such party for the increased
         costs to such Lender or such party of such increased capital. A
         certificate of any Lender setting forth in reasonable detail the
         computation of any such increased costs, delivered by such Lender to
         the Borrower shall, in the absence of manifest error, be conclusive and
         binding on the Borrower for all purposes. The 


                                       36
<PAGE>   43
         obligations of the Borrower under this Clause 13.3 shall survive the
         payment and performance of the Borrower's obligations under this
         Agreement and the termination of this Agreement; provided, however,
         that any Lender must submit a demand for payment pursuant to this
         provision within six (6) months after such Lender has first
         conclusively determined that such reimbursement or compensation is due
         such Lender under this and similar agreements.

13.4     Mitigation

         Any Lender which becomes aware of (i) any Change of Law which will make
         it unlawful or impossible for such Lender to make or maintain its
         Contribution or (ii) any Change of Law or other event or condition
         which will obligate Borrower to pay any amount pursuant to Clause 13.2
         or Clause 13.3 shall notify the Borrower and the Agent thereof as
         promptly as practical. If any Lender that has given notice of any such
         Change of Law or other event or condition thereafter becomes aware that
         such Change of Law or other event or condition has ceased to exist,
         such Lender shall notify the Borrower and the Agent thereof as promptly
         as practical. Each Lender affected by any Change of Law which makes it
         unlawful or impossible for such Lender to make or maintain its
         Contribution or to which the Borrower is obligated to pay any amount
         pursuant to Clause 13.2 or Clause 13.3 shall use reasonable commercial
         efforts (including changing the jurisdiction of its lending office) to
         avoid the effect of such Change of Law or to avoid or materially reduce
         any amounts which Borrower is obligated to pay pursuant to Clause 13.2
         or Clause 13.3 if, in the reasonable opinion of such Lender, such
         efforts would not be disadvantageous to such Lender or contrary to such
         Lender's normal banking practices.


14.      SET-OFF AND PRO RATA PAYMENTS

14.1     Set-off

         The Borrower authorizes each Lender to apply any credit balance to
         which the Borrower is then entitled on any account of the Borrower with
         the Lender at any of its branches in or towards satisfaction of any sum
         then due and payable from the Borrower to the Lender under this
         Agreement. For this purpose each Lender 


                                       37
<PAGE>   44
         is authorized to purchase with the moneys standing to the credit of any
         such account such other currencies as may be necessary to effect that
         application. None of the Lenders shall be obliged to exercise any right
         given to it by this Clause 14.1. Each Lender shall notify the Agent and
         the Borrower immediately on the exercise or purported exercise of any
         right of set-off, giving full details in relation thereto and the Agent
         shall inform the other Lenders.

14.2     Pro rata payments

         (a)      If at any time any Lender (the "Recovering Lender") receives
                  or recovers any amount owing to it by the Borrower under this
                  Agreement by direct payment, set-off or in any manner other
                  than by payment through the Agent pursuant to Clause 8.1 or
                  Clause 8.10, the Recovering Lender shall, within two Banking
                  Days of such receipt or recovery (a "Direct Receipt") notify
                  the Agent of the amount of the Direct Receipt. If the Direct
                  Receipt exceeds the amount which the Recovering Lender would
                  have received if the Direct Receipt had been received by the
                  Agent and distributed pursuant to Clause 8.1 or Clause 8.10
                  (as the case may be) then:

                  (i)     within two Banking Days of demand by the Agent, the
                          Recovering Lender shall pay to the Agent an amount
                          equal (or equivalent) to the excess;

                  (ii)    the Agent shall treat the excess amount so paid by the
                          Recovering Lender as if it were a payment made by the
                          Borrower and shall distribute the same to the Lenders
                          (other than the Recovering Lender) in accordance with
                          Clause 8.1 or Clause 8.10, as appropriate; and

                  (iii)   as between the Borrower and the Recovering Lender the
                          excess amount so re-distributed shall be treated as
                          not having been paid but the obligations of the
                          Borrower to the other Lenders shall, to the extent of
                          the amount so re-distributed to them, be treated as
                          discharged.


                                       38
<PAGE>   45
         (b)      If any part of the Direct Receipt subsequently has to be
                  wholly or partly refunded by the Recovering Lender each Lender
                  to which any part of such Direct Receipt was so re-distributed
                  shall on request from the Recovering Lender repay to the
                  Recovering Lender its pro rata share of the amount which has
                  to be refunded by the Recovering Lender.

         (c)      Each Lender shall on request supply to the Agent such
                  information as the Agent may from time to time request for the
                  purpose of this Clause 14.2.

         (d)      Any amount received or recovered by a Lender under a transfer,
                  assignment, sub-participation (or the like) shall be ignored
                  for the purpose of this Clause 14.2.

15.      ASSIGNMENT, SUBSTITUTION AND LENDING OFFICES

15.1     Benefit and burden

         This Agreement shall be binding upon, and enure for the benefit of, the
         Lenders, the Agent and the Borrower and their respective successors and
         Substitutes. This Agreement shall also enure for the benefit of the
         Arranger.

15.2     No assignment by Borrower

         The Borrower may not assign, transfer or otherwise dispose of any of
         its rights or obligations under this Agreement without the prior
         written consent of the Agent and each Lender.

15.3     Participation

         Any Lender may, in its absolute discretion and without any requirement
         to obtain the consent of or to give notice or any information to any
         other party, grant one or more participating interests in its
         proportion of the Loan to any third party (a "Participant"). The
         granting of such a participating interest shall not affect the relevant
         Lender's rights and obligations under this Agreement nor shall the
         Participant acquire any rights or assume any obligations under this
         Agreement other than with the agreement of the Borrower and the Agent.


                                       39
<PAGE>   46
15.4     Transfer

         Otherwise than in accordance with this Clause 15.4, each Lender may not
         assign all or any of its rights hereunder. Each Lender (a "Transferring
         Lender") may, in its absolute discretion and without any requirement to
         obtain the consent of any other party (other than the consent of the
         Agent and (if no Default shall have occurred or be continuing) the
         Borrower, which consent shall not be unreasonably withheld or delayed),
         transfer all or any part of its rights, benefits and/or obligations
         under this Agreement to another person (a "Substitute"), provided that
         the amount to be transferred shall not be less than (Y)500,000,000. Any
         such transfer shall be effected on five Banking Days' prior notice by
         delivery to the Agent of a duly completed Substitution Certificate duly
         executed by the Transferring Lender and the Substitute (which the Agent
         shall promptly execute for itself, the Borrower and the other Lenders
         (the "other parties")). Subject to the execution of that Substitution
         Certificate by all parties to it, on the effective date specified in a
         Substitution Certificate, to the extent that they are expressed in that
         Substitution Certificate to be the subject of the transfer effected
         pursuant to this Clause 15.4:

         (a)      the other parties and the Transferring Lender shall be
                  released from their respective obligations towards one another
                  under this Agreement (the "discharged obligations") and their
                  respective rights against one another under this Agreement
                  (the "discharged rights") shall be cancelled;

         (b)      the relevant Substitute and the other parties shall assume
                  obligations towards each other which differ from the
                  discharged obligations only insofar as they are owed to or
                  assumed by that Substitute instead of to or by the
                  Transferring Lender; and

         (c)      the relevant Substitute and the other parties shall acquire
                  rights against each other which differ from the discharged
                  rights only insofar as they are exercisable by or against such
                  Substitute instead of by or against the Transferring Lender.


                                       40
<PAGE>   47
         The Agent shall promptly notify the other parties of the receipt by it
         of any Substitution Certificate and shall promptly deliver a copy of
         that Substitution Certificate to the Borrower.

15.5     Reliance on Substitution Certificate

         The Agent and the Borrower may rely on any Substitution Certificate
         delivered to the Agent in accordance with the foregoing provisions of
         this Clause 15 which is complete and regular on its face as regards its
         contents and purportedly signed on behalf of the Transferring Lender
         and the Substitute and neither the Agent nor the Borrower shall have
         any liability or responsibility to any party as a consequence of
         placing reliance on and acting in accordance with any such Substitution
         Certificate if it proves to be the case that the same was not authentic
         or duly authorized.

15.6     Authorization of Agent

         The Borrower and each Lender irrevocably authorizes the Agent to
         counter-sign each Substitution Certificate on its behalf without any
         further consent of, or consultation with, the Borrower or such Lender.

15.7     Construction of certain references

         If any Lender transfers any of its rights, benefits and obligations as
         provided in Clause 15.4 all relevant references in this Agreement to
         such Lender shall thereafter be construed as a reference to that Lender
         and/or its Substitute (as the case may be) to the extent of their
         respective interests.

15.8     Lending offices

         Each Lender shall lend through its office at the address specified in
         Schedule 1 or, as the case may be, in any relevant Substitution
         Certificate or through any other office of that Lender selected from
         time to time by that Lender through which such Lender wishes to lend
         for the purposes of this Agreement. If the office through which a
         Lender is lending is changed pursuant to this Clause 15.8, the Lender
         shall notify the Agent promptly of that change. Before a Lender changes
         its lending office pursuant to this Clause 15.8, such Lender shall


                                       41
<PAGE>   48
         consider whether such change will increase the amounts payable by the
         Borrower to such Lender under this Agreement.

15.9     Disclosure of information

         Any Lender may disclose to a prospective transferee or Substitute or to
         any other Person who may propose entering into contractual relations
         with that Lender in relation to this Agreement such information about
         the Borrower as the Lender shall consider appropriate, subject to
         Clause 17.5.

16.      ARRANGER, AGENT AND REFERENCE LENDERS

16.1     Appointment of Agent

         Each Lender irrevocably appoints the Agent as its agent for the
         purposes of this Agreement and the Guaranty and authorizes the Agent
         (whether or not by or through employees or agents) to take such action
         on such Lender's behalf and to exercise such rights, remedies, powers
         and discretions as are specifically delegated to the Agent by this
         Agreement, together with such powers and discretions as are reasonably
         incidental thereto. Neither the Agent nor the Arranger shall, however,
         have any duties, obligations or liabilities to the Lenders beyond those
         expressly stated in this Agreement.

16.2     Amendments; Waivers

         (a)      Subject to Clause 16.2(b), the Agent may, with the consent of
                  the Majority Lenders (or if and to the extent expressly
                  authorized by the other provisions of this Agreement), (i)
                  agree to amendments or modifications to this Agreement with
                  the Borrower and/or (ii) vary or waive breaches of, or
                  defaults under, or otherwise excuse performance of, any
                  provision of this Agreement by the Borrower. Any such action
                  so authorized and effected by the Agent shall be documented in
                  such manner as the Agent shall (with the approval of the
                  Majority Lenders) determine, shall be promptly notified to the
                  Lenders by the Agent and shall be binding on all the Lenders.

         (b)      Except with the prior written consent of all the Lenders, the
                  Agent shall not have authority on behalf of the Lenders to
                  agree with the Borrower to 


                                       42
<PAGE>   49
                  any amendment or modification to this Agreement or to grant
                  waivers in respect of breaches or defaults or to vary or
                  excuse performance of or under this Agreement by the Borrower,
                  if the effect of such amendment, modification, waiver,
                  variation or excuse would be to (i) reduce any applicable
                  Margin, (ii) postpone the due date or reduce the amount of any
                  payment of principal, interest or other amount payable by the
                  Borrower under this Agreement, (iii) change the currency in
                  which any amount is payable by the Borrower under this
                  Agreement, (iv) increase any Lender's Commitment, (v) change
                  the definition of "Majority Lenders" in Clause 1.2, (vi)
                  change any provision of this Agreement which expressly or
                  impliedly requires the approval or consent of all the Lenders
                  such that the relevant approval or consent may be given
                  otherwise than with the sanction of all the Lenders, (vii)
                  change the order of distribution under Clause 8.10, (viii)
                  change Clause 14.2 or (ix) change this Clause 16.2.

16.3     Rights of Agent as Lender; No partnership

         With respect to its own Commitment and Contribution (if any) the Agent
         shall have the same rights and powers under this Agreement and the
         Guaranty as any other Lender and may exercise the same as though it
         were not performing the duties and functions delegated to it under this
         Agreement and the term "Lenders" shall, unless the context clearly
         otherwise indicates, include the Agent in its individual capacity as a
         Lender. This Agreement shall not and shall not be construed so as to
         constitute a partnership between the parties or any of them.

16.4     No liability of Arranger and Agent

         Neither the Arranger nor the Agent shall:

         (a)      be obliged to request any certificate under Clause 10.1 or to
                  make any enquiry as to the use of the proceeds of the Loan
                  unless (in the case of the Agent) so required in writing by
                  any Lender, in which case the Agent shall promptly make the
                  appropriate request of the Borrower, or be obliged to make any
                  enquiry as to any default by the Borrower in the performance
                  or observance of any of the provisions of this Agreement or as
                  to the existence of a Default unless (in the case of the
                  Agent) the Agent has actual 


                                       43
<PAGE>   50
                  knowledge thereof or has been notified in writing thereof by a
                  Lender, in which case the Agent shall promptly notify the
                  Lenders of the relevant event or circumstance; or

         (b)      be liable to any Lender for any action taken or omitted under
                  or in connection with this Agreement unless caused by its
                  gross negligence or willful misconduct.

         For the purposes of this Clause 16 the Agent shall not be treated as
         having actual knowledge of any matter of which the corporate finance or
         any other division outside the agency or loan administration department
         of the person for the time being acting as the Agent may become aware
         in the context of corporate finance, advisory or lending activities
         from time to time undertaken by the Agent for the Borrower or any of
         its subsidiaries or associated companies or any other person which may
         be a trade competitor of the Borrower or may otherwise have commercial
         interests similar to those of the Borrower.

16.5     Agent's duty to notify and take action

         The Agent shall:

         (a)      promptly notify each Lender of the contents of each notice,
                  certificate or other document received by the Agent from the
                  Borrower under or pursuant to Clauses 10.1(a) or 10.1(e); and

         (b)      (subject to its being indemnified to its satisfaction) take
                  such action or, as the case may be, refrain from taking such
                  action with respect to any Default of which the Agent has
                  actual knowledge as the Majority Lenders may reasonably
                  direct.

16.6     Identity of Lenders

         The Agent may deem and treat (a) each Lender as the person entitled to
         the benefit of the Contribution of such Lender for all purposes of this
         Agreement unless and until a Substitution Certificate shall have been
         filed with the Agent, and (b) the office set opposite the name of each
         Lender in Schedule 1 or, as the 


                                       44
<PAGE>   51
         case may be, in any relevant Substitution Certificate as such Lender's
         lending office unless and until a written notice of change of lending
         office shall have been received by the Agent; and the Agent may act
         upon any such notice unless and until the same is superseded by a
         further such notice.

16.7     Non-reliance on Arranger or Agent

         Each Lender acknowledges that it has not relied on any statement,
         opinion, forecast or other representation made by the Arranger or the
         Agent to induce it to enter into this Agreement and that it has made
         and will continue to make, without reliance on the Agent or the
         Arranger and based on such documents as it considers appropriate, its
         own appraisal of the creditworthiness of the Borrower and its own
         independent investigation of the financial condition and affairs of the
         Borrower in connection with the making and continuation of the Loan
         under this Agreement. Neither the Arranger nor the Agent shall have any
         duty or responsibility, either initially or on a continuing basis, to
         provide any Lender with any credit or other information with respect to
         the Borrower whether coming into its possession before the making of
         any Advance or at any time or times thereafter, other than (in the case
         of the Agent) as provided in Clause 16.5(a).

16.8     No Responsibility on Arranger or Agent for Borrower's performance

         Neither the Arranger nor the Agent shall have any responsibility to any
         Lender on account of the failure of the Borrower or the Guarantor to
         perform its obligations under this Agreement or the Guaranty or for the
         financial condition of the Borrower or the Guarantor or for the
         completeness or accuracy of any statements, representations or
         warranties in this Agreement or the Guaranty or any document delivered
         under this Agreement or for the execution, effectiveness, adequacy,
         genuineness, validity, enforceability or admissibility in evidence of
         this Agreement or of any certificate, report or other document executed
         or delivered under this Agreement or its negotiation or for acting (or,
         as the case may be, refraining from acting) in accordance with the
         instructions of the Majority Lenders. The Arranger and the Agent shall
         be entitled to rely on any communication, instrument or document
         believed by it to be genuine and correct and to have been signed or
         sent by the proper person and shall be entitled to rely 


                                       45
<PAGE>   52
         as to legal or other professional matters on opinions and statements of
         any legal or other professional advisers selected or approved by it.

16.9     Other dealings

         The Arranger and the Agent may, without any liability to account to the
         Lenders, accept deposits from, lend money to, and generally engage in
         any kind of banking or trust business with, the Borrower or any of its
         subsidiaries or associated companies or any of the Lenders as if it
         were not the Arranger or the Agent as the case may be.

16.10    Reimbursement and indemnity by Lenders

         Each Lender shall reimburse the Arranger and the Agent (ratably in
         accordance with such Lender's Commitment or Contribution), to the
         extent that the Arranger or the Agent is not reimbursed by the Borrower
         or the Guarantor, for the charges and expenses incurred by the Arranger
         and the Agent in connection with the contemplation of, or otherwise in
         connection with, the enforcement of, or the preservation of any rights
         under, or in carrying out its duties under, this Agreement including
         (in each case) the fees and expenses of legal or other professional
         advisers. Each Lender shall indemnify the Agent (ratably in accordance
         with its Commitment or Contribution) against all liabilities, damages,
         costs and claims whatsoever incurred by the Agent in connection with
         this Agreement or the performance of its duties under this Agreement or
         any action taken or omitted by the Agent under this Agreement, unless
         such liabilities, damages, costs or claims arise from the Agent's own

        1. DEFINITIONS AND INTERPRETATION.

           (a)  Definitions. When used in this Guaranty, the following terms 
        shall have the following respective meanings:

                "Affiliate" shall mean, with respect to any Person, (a) each
        Person that, directly or indirectly, owns or controls, whether

        Person that controls, is controlled by or is under common control with

        For the purpose of this definition, "control" of a Person shall mean the
        possession, directly or indirectly, of the power to direct or cause the

        change in the Base Rate resulting from a change in the Prime Rate shall
        become effective on the Business Day on which each change in the Prime
        Rate occurs.)

        A hereof.

                "Borrower Loan Agreement" shall have the meaning given to that

        Person's balance sheet.

                "Capital Expenditures" shall mean, with respect to any Person
        and any period, all amounts expended and indebtedness incurred or
        assumed by such Person during such period for the acquisition of Capital

        2. GUARANTY.

                (a) Payment Guaranty. Guarantor unconditionally guarantees and
        promises to pay and perform as and when due, whether at stated maturity,
        upon acceleration or otherwise, any and all of the Guaranteed
        Obligations. If any Insolvency Proceeding relating to Borrower is
        commenced, Guarantor further unconditionally guarantees and promises to
        pay and perform, upon the demand of Agent, any and all of the Guaranteed
        Obligations (including any and all Disallowed Post-Commencement Interest
        and Expenses) in accordance with the terms of the Borrower Loan
        Documents, whether or not such obligations are then due and payable by
        Borrower and whether or not such obligations are modified, reduced or
        discharged in such Insolvency Proceeding. This Guaranty is a guaranty of
        payment and not of collection.

                (b) Continuing Guaranty. This Guaranty is an irrevocable
        continuing guaranty of the Guaranteed Obligations which shall continue
        in effect until all obligations of the Lenders to extend credit to
        Borrower have terminated and all of the Guaranteed Obligations have been
        fully, finally and indefeasibly paid. If any payment on any Guaranteed
        Obligation is set aside, avoided or rescinded or otherwise recovered
        from Agent or any Lender, such recovered payment shall constitute a
        Guaranteed Obligation hereunder and, if this Guaranty was previously
        released or terminated, it automatically shall be fully reinstated, as
        if such payment was never made.

                (c) Independent Obligation. The liability of Guarantor hereunder
        is independent of the Guaranteed Obligations, and a separate action or
        actions may be brought and prosecuted against Guarantor irrespective of
        whether action is brought against Borrower or any other guarantor of the
        Guaranteed Obligations or whether Borrower or any other guarantor of the
        Guaranteed Obligations is joined in any such action or actions.

                (d) Fraudulent Transfer Limitation. If, in any action to enforce
        this Guaranty, any court of competent jurisdiction determines that
        enforcement against Guarantor for the full amount of the Guaranteed
        Obligations is not lawful under or would be subject to avoidance under
        Section 548 of the United States Bankruptcy Code or any applicable
        provision of any comparable law of any state or other jurisdiction, the
        liability of Guarantor under this Guaranty shall be limited to the
        maximum amount lawful and not subject to such avoidance.



                                       15
<PAGE>   16

                (e) Termination. 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 Agent or any Lender after receipt.


        3. REPRESENTATIONS AND WARRANTIES. Guarantor hereby represents and
warrants to Agent and the Lenders as follows:

                (a) Due Incorporation, Qualification, Etc. Each of Guarantor and
        Guarantor's Subsidiaries (i) is a corporation duly organized, validly
        existing and in good standing under the laws of its state of
        incorporation; (ii) has the power and authority to own, lease and
        operate its properties and carry on its business as now conducted; and
        (iii) is duly qualified, licensed to do business and in good standing as
        a foreign corporation in each jurisdiction where the failure to be so
        qualified or licensed is reasonably likely to have a Material Adverse
        Effect.

                (b) Authority. The execution, delivery and performance by
        Guarantor of each Borrower Loan Document executed, or to be executed, by
        Guarantor and the consummation of the transactions contemplated thereby
        (i) are within the power of Guarantor and (ii) have been duly authorized
        by all necessary actions on the part of Guarantor.

                (c) Enforceability. Each Borrower Loan Document executed, or to
        be executed, by Guarantor has been, or will be, duly executed and
        delivered by Guarantor and constitutes, or will constitute, a legal,
        valid and binding obligation of Guarantor, enforceable against Guarantor
        in accordance with its terms, except as limited by bankruptcy,
        insolvency or other laws of general application relating to or affecting
        the enforcement of creditors' rights generally and general principles of
        equity.

                (d) Non-Contravention. The execution and delivery by Guarantor
        of the Borrower Loan Documents executed by Guarantor and the performance
        and consummation of the transactions contemplated thereby do not (i)
        violate any Requirement of Law applicable to Guarantor; (ii) violate any
        provision of, or result in the breach or the acceleration of, or entitle
        any other Person to accelerate (whether after the giving of notice or
        lapse of time or both), any Contractual Obligation of Guarantor; or
        (iii) result in the creation or imposition of any Lien (or the
        obligation to create or impose any Lien) upon any property, asset or
        revenue of Guarantor.

                (e) Approvals. No consent, approval, order or authorization of,
        or registration, declaration or filing with, any Governmental Authority
        or other Person (including, without limitation, the shareholders of any
        Person) is required in connection with the execution and delivery of the
        Borrower Loan Documents executed by Guarantor and the performance and
        consummation of the transactions contemplated thereby, except such as
        have been made or obtained and are in full force and effect.



                                       16
<PAGE>   17
                (f) No Violation or Default. Neither Guarantor nor any of its
        Subsidiaries is in violation of or in default with respect to (i) any
        Requirement of Law applicable to such Person; (ii) any Contractual
        Obligation of such Person (nor is there any waiver in effect which, if
        not in effect, would result in such a violation or default), where, in
        each case, such violation or default is reasonably likely to have a
        Material Adverse Effect. Without limiting the generality of the
        foregoing, neither Guarantor nor any of its Subsidiaries (A) has
        violated any Environmental Laws, (B) has any liability under any
        Environmental Laws or (C) has received notice or other communication of
        an investigation or is under investigation by any Governmental Authority
        having authority to enforce Environmental Laws, where such violation,
        liability or investigation is reasonably likely to have a Material
        Adverse Effect. No Event of Default or Default has occurred and is
        continuing.

                (g) Litigation. No actions (including, without limitation,
        derivative actions), suits, proceedings or investigations are pending
        or, to the knowledge of Guarantor, threatened against Guarantor or any
        of its Subsidiaries at law or in equity in any court or before any other
        Governmental Authority which (i) is reasonably likely (alone or in the
        aggregate) to have a Material Adverse Effect or (ii) seeks to enjoin,
        either directly or indirectly, the execution, delivery or performance by
        Guarantor of the Borrower Loan Documents executed by Guarantor or the
        transactions contemplated thereby. 

                (h) Title; Possession Under Leases. Guarantor and its
        Subsidiaries (i) own and have good and marketable title (without regard
        to minor defects of title) to the real property owned by Guarantor and
        its Subsidiaries, as reflected in the most recent Financial Statements
        delivered to Agent (except those assets and properties disposed of since
        the date of such Financial Statements in compliance with this Guaranty),
        (ii) have valid leasehold interests in all real property leased by
        Guarantor and its Subsidiaries, (iii) own and have good title (without
        regard to minor defects of title) to all their other respective
        properties and assets which are material to the business of Guarantor
        and its Subsidiaries, as reflected in the most recent Financial
        Statements delivered to Agent (except those assets and properties
        disposed of since the date of such Financial Statements in compliance
        with this Guaranty) and (iv) own and have good title (without regard to
        minor defects of title) to all respective properties and assets acquired
        by Guarantor and its Subsidiaries since such date which are material to
        the business of Guarantor and its Subsidiaries (except those assets and
        properties disposed of in compliance with this Guaranty). Such assets
        and properties are subject to no Lien, except for Permitted Liens. Each
        of Guarantor and its Subsidiaries enjoys peaceful and undisturbed
        possession under all leases, except for any failure to enjoy such
        possession which (alone or in the aggregate with any other such
        failures) is not reasonably likely to have a Material Adverse Effect.

                (i) Financial Statements. The Financial Statements of Guarantor
        and its Subsidiaries which have been delivered to Agent, (i) are in
        accordance with the books and records of Guarantor and its Subsidiaries,
        which have been maintained in accordance with good business practice;
        (ii) have been prepared in conformity with GAAP; and (iii) fairly
        present the financial conditions and results of operations of Guarantor
        and its Subsidiaries 



                                       17
<PAGE>   18

        as of the date thereof and for the period covered thereby. Neither
        Guarantor nor any of its Subsidiaries has any contingent obligations,
        liability for taxes or other outstanding obligations which are material
        in the aggregate, except as disclosed in the audited Financial
        Statements of Guarantor and its Subsidiaries for the fiscal year ending
        June 30, 1997, and the unaudited Financial Statements of Guarantor and
        its Subsidiaries for the fiscal quarter ending March 31, 1998, furnished
        by Guarantor to Agent prior to the date hereof, or in the Financial
        Statements delivered to Agent and Lenders pursuant to clause (i) or (ii)
        of Subparagraph 4(a) hereof.

                (j) Equity Securities. As of the date of this Guaranty, the
        authorized Equity Securities of Guarantor consist of ninety million
        (90,000,000) shares of common stock. All outstanding Equity Securities
        of Guarantor are duly authorized, validly issued, fully paid and
        non-assessable. All Equity Securities of Guarantor have been offered and
        sold in compliance with all federal and state securities laws and all
        other Requirements of Law.

                (k) No Agreements to Sell Assets, Etc. Neither Guarantor nor any
        of its Subsidiaries has any legal obligation, absolute or contingent, to
        any Person to sell the assets of Guarantor or any of its Subsidiaries
        (other than sales in the ordinary course of business), or to effect any
        merger, consolidation or other reorganization of Guarantor or any of its
        Subsidiaries or to enter into any agreement with respect thereto, except
        to the extent otherwise permitted pursuant to Subparagraph 5(c) and 5(d)
        hereof.

                (l) Employee Benefit Plans.

                        (i) Based on the latest valuation of each Employee
                Benefit Plan that either Guarantor or any ERISA Affiliate
                maintains or contributes to, or has any obligation under (which
                occurred within twelve months of the date of this
                representation), the aggregate benefit liabilities of such plan
                within the meaning of Section 4001 of ERISA did not exceed the
                aggregate value of the assets of such plan. Neither Guarantor
                nor any ERISA Affiliate has any liability with respect to any
                post-retirement benefit under any Employee Benefit Plan which is
                a welfare plan (as defined in section 3(1) of ERISA), other than
                liability for health plan continuation coverage described in
                Part 6 of Title I(B) of ERISA, which liability for health plan
                contribution coverage is not reasonably likely to have a
                Material Adverse Effect.

                        (ii) Each Employee Benefit Plan complies, in both form
                and operation, in all material respects, with its terms, ERISA
                and the Code, and no condition exists or event has occurred with
                respect to any such plan which would result in the incurrence by
                either Guarantor or any ERISA Affiliate of any material
                liability, fine or penalty. Each Employee Benefit Plan, related
                trust agreement, arrangement and commitment of Guarantor or any
                ERISA Affiliate is legally valid and binding and in full force
                and effect. No Employee Benefit Plan is being audited or
                investigated by any government agency or is subject to any
                pending or 

                                       18
<PAGE>   19

                threatened claim or suit. Neither Guarantor nor any ERISA
                Affiliate nor any fiduciary of any Employee Benefit Plan has
                engaged in a prohibited transaction under section 406 of ERISA
                or section 4975 of the Code.

                        (iii) Neither Guarantor nor any ERISA Affiliate
                contributes to or has any material contingent obligations to any
                Multiemployer Plan. Neither Guarantor nor any ERISA Affiliate
                has incurred any material liability (including secondary
                liability) to any Multiemployer Plan as a result of a complete
                or partial withdrawal from such Multiemployer Plan under Section
                4201 of ERISA or as a result of a sale of assets described in
                Section 4204 of ERISA. Neither Guarantor nor any ERISA Affiliate
                has been notified that any Multiemployer Plan is in
                reorganization or insolvent under and within the meaning of
                Section 4241 or Section 4245 of ERISA or that any Multiemployer
                Plan intends to terminate or has been terminated under Section
                4041A of ERISA.

                (m) Other Regulations. Guarantor is not subject to regulation
        under the Investment Company Act of 1940, the Public Utility Holding
        Company Act of 1935, the Federal Power Act, the Interstate Commerce Act,
        any state public utilities code or to any other Governmental Rule
        limiting its ability to incur indebtedness.

                (n) Patent and Other Rights. Guarantor and its Subsidiaries own
        or license under validly existing agreements, and have the full right to
        license without the consent of any other Person (or can demonstrate to
        the satisfaction of the Majority Lenders the ability to obtain or
        maintain), all patents, licenses, trademarks, trade names, trade
        secrets, service marks, copyrights and all rights with respect thereto,
        which are material to the conduct of their businesses as now conducted.

                (o) Governmental Charges and Other Indebtedness. Guarantor and
        its Subsidiaries have filed or caused to be filed all tax returns which
        are required to be filed by them. Guarantor and its Subsidiaries have
        paid, or made provision for the payment of, all taxes and other
        Governmental Charges which have or may have become due pursuant to said
        returns or otherwise and all other indebtedness, except such
        Governmental Charges or indebtedness, if any, which are being contested
        in good faith and as to which adequate reserves (determined in
        accordance with GAAP) have been provided or which are not reasonably
        likely to have a Material Adverse Effect if unpaid.

                (p) Margin Stock. Guarantor owns no Margin Stock which, in the
        aggregate, would constitute a substantial part of the assets of
        Guarantor, and no proceeds of any loan under the Borrower Loan Agreement
        will be used to purchase or carry, directly or indirectly, any Margin
        Stock or to extend credit, directly or indirectly, to any Person for the
        purpose of purchasing or carrying any Margin Stock.

                (q) Subsidiaries, etc. Set forth in Schedule 3(q) (as
        supplemented by Guarantor from time to time in a written notice to Agent
        and the Lenders) is a complete list of all of Guarantor's Subsidiaries,
        the jurisdiction of incorporation of each, and the percentage of shares
        of such Subsidiary owned directly or indirectly by Guarantor (which 



                                       19
<PAGE>   20

        in the event there is more than one class of Equity Securities and/or
        Guarantor, directly or indirectly, owns less than 100% of any Equity
        Securities of such Subsidiary, such information shall list the classes
        of Equity Securities and/or the number and percentage of Equity
        Securities owned directly or indirectly by Guarantor). Except for such
        Subsidiaries, Guarantor has no Subsidiaries, is not a partner in any
        partnership or a joint venturer in any joint venture.

                (r) Catastrophic Events. Neither Guarantor nor any of its
        Subsidiaries and none of their properties is or has been affected by any
        fire, explosion, accident, strike, lockout or other labor dispute,
        drought, storm, hail, earthquake, embargo, act of God or other casualty
        that is reasonably likely to have a Material Adverse Effect. There are
        no disputes presently subject to grievance procedure, arbitration or
        litigation under any of the collective bargaining agreements, employment
        contracts or employee welfare or incentive plans to which Guarantor or
        any of its Subsidiaries is a party, and there are no strikes, lockouts,
        work stoppages or slowdowns, or, to the best knowledge of Guarantor,
        jurisdictional disputes or organizing activities occurring or threatened
        which alone or in the aggregate are reasonably likely to have a Material
        Adverse Effect.

                (s) Burdensome Contractual Obligations, Etc. Neither Guarantor
        nor any of its Subsidiaries and none of their properties is subject to
        any Contractual Obligation or Requirement of Law which is reasonably
        likely to have a Material Adverse Effect.

                (t) No Material Adverse Effect. No event has occurred and no
        condition exists which is reasonably likely to have a Material Adverse
        Effect.

                (u) Accuracy of Information Furnished. None of the Borrower Loan
        Documents and none of the other certificates, statements or information
        furnished to Agent or any Lender by or on behalf of Borrower, Guarantor
        or any of its Subsidiaries in connection with the Borrower Loan
        Documents or the transactions contemplated thereby contains or will
        contain any untrue statement of a material fact or omits or will omit to
        state a material fact necessary to make the statements therein, in light
        of the circumstances under which they were made, not misleading.


        4. AFFIRMATIVE COVENANTS. Until all obligations of Agent or any Lender
to extend credit to Guarantor have terminated and all of the Guaranteed
Obligations have been fully, finally and indefeasibly paid, Guarantor shall
comply, and shall cause compliance, with the following affirmative covenants,
unless Majority Lenders shall otherwise consent in writing:

                (a) Financial Statements, Reports, etc. Guarantor shall furnish
        to Agent for each Lender the following, each in such form and such
        detail as Agent shall reasonably request (copies of which Agent shall
        promptly deliver to each Lender):

                        (i) As soon as available and in no event later than

                its Subsidiaries (prepared on a consolidated basis) for such


                                       20
<PAGE>   21

                quarter and for the fiscal year to date, certified by the chief
                executive officer, president, chief financial officer or
                treasurer of Guarantor to present fairly the financial
                condition, results of operations and other information reflected
                therein and to have been prepared in accordance with GAAP
                (subject to normal year-end audit adjustments);

                        (ii) As soon as available and in no event later than one
                hundred (100) days after the close of each fiscal year of
                Guarantor, (A) copies of the audited Financial Statements of
                Guarantor and its Subsidiaries (prepared on a consolidated
                basis) for such year, prepared by independent certified public
                accountants of recognized national standing acceptable to Agent,
                and (B) copies of the unqualified opinions (or qualified
                opinions reasonably acceptable to Agent) and management letters
                delivered by such accountants in connection with all such
                Financial Statements;

                        (iii) Contemporaneously with the quarterly and year-end

                this Guaranty and the other Borrower Loan Documents as Agent may
                from time to time reasonably request.

                (b) Books and Records. Guarantor and its Subsidiaries shall at

        Default or Event of Default has occurred and is continuing, such
        inspection and examination by any Lender (other than Agent) shall be at
        the expense of such Lender.

                request, schedules setting forth all insurance then in effect.

        its Subsidiaries shall promptly pay and discharge when due (i) all taxes
        and other Governmental Charges prior to the date upon which penalties
        accrue thereon, (ii) all indebtedness which, if unpaid, could become a
        Lien upon the property of Guarantor or its Subsidiaries and (iii) all
        other Indebtedness which, if unpaid, is reasonably likely to have a
        Material Adverse Effect, except such Indebtedness as may in good faith
        be contested or disputed, or for which arrangements for deferred payment
        have been made, provided that in each such case appropriate reserves are
        maintained to the reasonable satisfaction of Agent.

                (f) Use of Proceeds. Borrower shall not use any part of the
        proceeds of any loan under the Borrower Loan Agreement, directly or
        indirectly, for the purpose of purchasing or carrying any Margin Stock
        or for the purpose of purchasing or carrying or trading in any
        securities under such circumstances as to involve Guarantor, any Lender
        or Agent in a violation of Regulations T, U or X issued by the Federal
        Reserve Board.

                (g) General Business Operations. Except as permitted in
        Subparagraph 5(d) hereof, each of Guarantor and its Subsidiaries shall
        (i) preserve and maintain its corporate existence and all of its rights,
        privileges and franchises reasonably necessary to the conduct of its
        business; provided, however, that from time to time, Guarantor may, in
        the ordinary course of business, dissolve any Subsidiary which is not a
        Material Subsidiary, so long as both immediately before and after giving
        effect to such dissolution, no Default or Event of Default shall have
        occurred and be continuing, (ii) conduct its business activities in
        compliance with all Requirements of Law and Contractual Obligations
        applicable to such Person, the violation of which is reasonably likely
        to have a Material Adverse Effect, and (iii) keep all property useful
        and necessary in its business in good working order and condition,
        ordinary wear and tear excepted. Guarantor shall maintain its chief
        executive office and principal place of business in the United States.

                (h) Pari Passu Ranking. Guarantor shall take, or cause to be
        taken, all actions necessary to ensure that the obligations of Guarantor
        under this Guaranty are and continue to rank at least pari passu in
        right of payment with all other unsecured Senior Indebtedness of
        Guarantor.


        5. NEGATIVE COVENANTS. Until all obligations of Agent or any Lender to
extend credit to Guarantor have terminated and all of the Guaranteed Obligations
have been fully, finally and indefeasibly paid, Guarantor shall comply, and

               Guarantor against Borrower, any other guarantor of the
               Guaranteed Obligations or any security, whether resulting from

                      (iv) Any setoff or counterclaim of Borrower or any defense

               the liability of Borrower (including, without limitation, the
               lack of validity or enforceability of any of the Borrower Loan
               Documents);

                      (v) Any defense based upon any law, rule or regulation

                      (vi) Until all obligations of Agent or any Lender to
               extend credit to Borrower have terminated and all of the
               Guaranteed Obligations have been fully, finally and indefeasibly
               paid, any right of subrogation, reimbursement, indemnification or
               contribution and other similar right to enforce any remedy which
               Agent, the Lenders or any other Person now has or may hereafter
               have against Borrower on account of the Guaranteed Obligations,
               and any benefit of, and any right to participate in, any security
               now or hereafter received by Agent, any Lender or any other
               Person on account of the Guaranteed Obligations;

                      (vii) All presentments, demands for performance, notices

               nonperformance of the Guaranteed Obligations;

                      (xi) Until all obligations of Agent or any Lender to
               extend credit to Borrower have terminated and all of the
               Guaranteed Obligations have been fully, finally and indefeasibly
               paid, any right to revoke this Guaranty;

                                       33

<PAGE>   34

                      (xii) Any defense arising from an election for the
               application of Section 1111(b)(2) of the United States Bankruptcy
               Code which applies to the Guaranteed Obligations;

                      (xiii) Any defense based upon any borrowing or grant of a
               security interest under Section 364 of the United States
               Bankruptcy Code; and

                      (xiv) Any right it may have to a fair value hearing to
               determine the size of a deficiency judgment following any
               foreclosure on any security for the Guaranteed Obligations.

        Without limiting the scope of any of the foregoing provisions of this
        Paragraph 6, Guarantor hereby further waives (A) all rights and defenses
        arising out of an election of remedies by Agent or any Lender, 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 Borrower by
        the operation of Section 580d of the Code of Civil Procedure or
        otherwise, (B) all rights and defenses Guarantor may have by reason of
        protection afforded to Borrower 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 Code of
        Civil Procedure, and (C) all other rights and defenses available to
        Guarantor by reason of Sections 2787 to 2855, inclusive, Section 2899 or
        Section 3433 of the California Civil Code or Section 3605 of the
        California Commercial Code.

               (c) Financial Condition of Borrower, Etc. Guarantor is fully
        aware of the financial condition and affairs of Borrower. Guarantor has
        executed this Guaranty without reliance upon any representation,
        warranty, statement or information concerning Borrower furnished to
        Guarantor by Agent or any Lender and has, independently and without
        reliance on Agent or any Lender, and based on such documents and
        information as it has deemed appropriate, made its own appraisal of the
        financial condition and affairs of Borrower and of other circumstances
        affecting the risk of nonpayment or nonperformance of the Guaranteed
        Obligations. Guarantor is in a position to obtain, and assumes full
        responsibility for obtaining, any additional information about the
        financial condition and affairs of Borrower and of other circumstances
        affecting the risk of nonpayment or nonperformance of the Guaranteed
        Obligations and will, independently and without reliance upon Agent or
        any Lender, and based on such documents and information as it shall deem
        appropriate at the time, continue to make its own appraisals and
        decisions in taking or not taking action in connection with this
        Guaranty.


        7. SUBORDINATION. Guarantor hereby subordinates any and all debts,
liabilities and obligations owed to Guarantor by Borrower (the "Subordinated
Obligations") to the Guaranteed Obligations as provided in this Paragraph 7.


                                       34

<PAGE>   35

               (a) Prohibited Payments, Etc. Until the occurrence of a Default
        or an Event of Default or any default by Guarantor hereunder, Guarantor
        may receive regularly scheduled payments from Borrower on account of
        Subordinated Obligations. After the occurrence and during the
        continuance of any Default or Event of Default or any default by
        Guarantor hereunder (including the commencement and continuation of any
        Insolvency Proceeding relating to Borrower), however, unless Agent
        otherwise agrees, Guarantor shall not demand, accept or take any action
        to collect any payment on account of the Subordinated Obligations.

               (b) Prior Payment of Guaranteed Obligations. In any Insolvency
        Proceeding relating to Borrower, Guarantor agrees that Agent and the
        Lenders shall be entitled to receive payment of all Guaranteed
        Obligations (including any and all Disallowed Post-Commencement Interest
        and Expenses) before Guarantor receives payment of any Subordinated
        Obligations.

               (c) Turn-Over. After the occurrence and during the continuance of
        any Default or Event of Default (including the commencement and
        continuation of any Insolvency Proceeding relating to Borrower),
        Guarantor shall, if Agent so requests, collect, enforce and receive
        payments on account of the Subordinated Obligations as trustee for Agent
        and the Lenders and deliver such payments to Agent on account of the
        Guaranteed Obligations (including any and all Disallowed
        Post-Commencement Interest and Expenses), together with any necessary
        endorsements or other instruments of transfer, but without reducing or
        affecting in any manner the liability of Guarantor under the other
        provisions of this Guaranty.

               (d) Agent Authorization. After the occurrence and during the
        continuance of any Default or Event of Default or any default by
        Guarantor hereunder (including the commencement and continuation of any
        Insolvency Proceeding relating to Borrower), Agent 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, Subordinated Obligations and to apply any amounts
        received thereon to the Guaranteed Obligations (including any and all
        Disallowed Post-Commencement Interest and Expenses), and (ii) to require
        Guarantor (A) to collect and enforce, and to submit claims in respect
        of, Subordinated Obligations and (B) to pay any amounts received on such
        obligations to Agent for application to the Guaranteed Obligations
        (including any and all Disallowed Post-Commencement Interest and
        Expenses).

               (b)    Payments.

                      (i) Guarantor shall make all payments required hereunder
               to Agent, or its order, at Agent's office located at the address
               set forth in Subparagraph 8(a) hereof, or at such other office as
               Agent may designate, on demand, in lawful money as provided in
               clause (ii) below and in same day or immediately available funds
               not later than 11:00 a.m. (Tokyo time) on the date due.

                      (ii) Guarantor shall make all payments of the Guaranteed
               Obligations hereunder in the currency in which such Guaranteed
               Obligations are required to be paid by Borrower pursuant to the
               Borrower Loan Documents and shall make all other payments
               hereunder in Yen or Dollars, as Agent may specify; provided,
               however, that, if Agent shall request Guarantor to pay any amount
               hereunder which would otherwise be payable in another currency in
               the lawful currency of the United States, Guarantor shall pay to
               Agent the Dollar Equivalent of such amount.

                      (iii) If any sum due from Guarantor under this Guaranty or
               any other Borrower Loan Document to which Guarantor is a party or
               any order, judgment or award given or rendered in relation hereto
               or thereto has to be converted from the currency (the "first
               currency") in which the same is payable hereunder or thereunder
               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 amounts 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 

                                       37

<PAGE>   38

               shall survive the giving or making of any judgment or order in
               relation to all or any of such obligations.

                      (iv) If any amounts required to be paid by Guarantor under
               this Guaranty or any order, judgment or award given or rendered
               in relation hereto remain unpaid after such amounts are due,
               Guarantor shall pay interest on the aggregate, outstanding
               balance of such amounts from the date due until those amounts are
               paid in full at a per annum rate equal to:

                             (A) In the case of amounts payable in Yen, the
                      Overnight Rate plus two percent (2.0%), such rate to
                      change from time to time as the Overnight Rate shall
                      change; or

                             (B) In the case of amounts payable in Dollars, the
                      Base Rate plus two percent (2.00%), such rate to change
                      from time to time as the Base Rate shall change.

               (c) Expenses. Guarantor shall pay on demand (i) all reasonable
        fees and expenses, including reasonable attorneys' fees and expenses,
        incurred by Agent in connection with the preparation, execution and
        delivery of, and the exercise of its duties under, this Guaranty and the
        preparation, execution and delivery of amendments and waivers hereunder
        and (ii) all reasonable fees and expenses, including reasonable
        attorneys' fees and expenses, incurred by Agent and the Lenders in
        connection with the enforcement or attempted enforcement of this
        Guaranty or any of the Guaranteed Obligations or in preserving any of
        Agent's or the Lenders' rights and remedies (including, without
        limitation, all such fees and expenses incurred in connection with any
        "workout" or restructuring affecting the Borrower Loan Documents or the
        Guaranteed Obligations or any bankruptcy or similar proceeding involving
        Guarantor, Borrower or any of their affiliates).

               (d) Waivers; Amendments. This Guaranty may not be amended or
        modified, nor may any of its terms be waived, except by written
        instruments signed by Guarantor and Agent. Each waiver or consent under
        any provision hereof shall be effective only in the specific instances
        for the purpose for which given. No failure or delay on Agent's or any
        Lender's part 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.

               (e) Assignments. This Guaranty shall be binding upon and inure to
        the benefit of Agent, the Lenders and Guarantor and their respective
        successors and assigns; provided, however, that Guarantor may not assign
        or transfer any of its rights and obligations under this Guaranty
        without the prior written consent of Agent and the Lenders, and,
        provided, further, that Agent or any Lender may sell, assign and
        delegate their respective rights and obligations hereunder only as
        permitted by the Borrower Loan Agreement. All references in this
        Guaranty to any Person shall be deemed to include all permitted
        successors and assigns of such Person.

                                       38

<PAGE>   39

               (f) Cumulative Rights, etc. The rights, powers and remedies of
        Agent and the Lenders under this Guaranty shall be in addition to all
        rights, powers and remedies given to Agent and the Lenders by virtue of
        any applicable Governmental Rule, the Borrower Loan Agreement, any other
        Borrower Loan Document or any other agreement (including any other
        guaranty), all of which rights, powers, and remedies shall be cumulative
        and may be exercised successively or concurrently without impairing
        Agent's or any Lender's rights hereunder.

               (g) 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 Agent or any Lender hereunder, the amounts so payable to
        Agent or such Lender shall be increased to the extent necessary to yield
        to Agent or such Lender (after payment of all such amounts) any such
        amounts payable hereunder in the amounts specified in this Guaranty.
        Upon request by Agent or any Lender, Guarantor shall furnish evidence
        satisfactory to Agent or such Lender 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.

               (h) 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.

               (i)    Governing Law, Consent to Jurisdiction, Etc.

                      (i) 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.

                     SECOND ADDENDUM TO EMPLOYMENT AGREEMENT

          This Second Addendum to Employment Agreement (the "Second Addendum")
is made and effective this 1st day of September, 1998, by and between Roger D.
Emerick (the "Executive") and Lam Research Corporation (the "Company").


                                 R E C I T A L S

     A.   The Executive is currently employed by the Company pursuant to an
Employment Agreement entered into by the parties effective as of July 1, 1996,
and as amended by Addendum dated June 26, 1997 (the "Employment Agreement"). The
Executive currently also serves as Chairman of the Company's Board of Directors.

     B.   Section 1(a) of the Employment Agreement provides, inter alia, that
the Company shall use its best efforts to elect the Executive as a director of
the Company and as Chairman of the Board of Directors. Section 3(a) identifies
certain Base Compensation payable to the Executive during the Employment Period.
Sections 8(d) and (e) identify certain circumstances which may constitute
termination, involuntary or otherwise, of the Executive's responsibilities and
trigger an acceleration of certain benefits or a change in the Executive's
employment status with the Company.

     C.   The Executive has tendered his voluntary resignation as Chairman of
the Board of Directors, effective September 1, 1998, and wishes to release the
Company from any further obligation or commitment to use efforts to elect him in
the future to the position as Chairman.

     D.   The Company and the Executive desire to amend further the Employment
Agreement to provide for the Executive's continued employment by the Company
following his resignation as Chairman of the Board of Directors.

     E.   Capitalized terms used in this Second Addendum and not otherwise
defined herein shall have the meanings ascribed to them in the Employment
Agreement.

          In consideration of the mutual covenants herein contained, and for
good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties agree that the Employment Agreement shall be and is
amended as follows:

          1.   Duties and Scope of Employment.

               (a)  The Executive shall continue as an employee of the Company
with, notwithstanding the provisions of the first sentence of Section 1(a) of
the Employment Agreement, such strategic, senior level duties and
responsibilities as the Company's Chief Executive Officer may from time to time
reasonably assign to the Executive.

               (b)  The Company shall continue to use its best efforts to elect
the Executive as a director of the Company. However, notwithstanding the
provisions of the second sentence of Section 1(a) of the Employment Agreement,
the Company shall be relieved of any obligation or commitment to use its efforts
to elect the Executive as Chairman of the Board of Directors.

          2.   Compensation and Benefits.

               (a)  Notwithstanding the provisions of the first sentence of
Section 3(a) of the Employment Agreement, during the Employment Period, and
commencing as of September 1, 1998, the Company shall pay the Executive as
compensation for services a base salary equivalent on an annualized basis to the
fee identified in Section 6(a) of the Employment Agreement.

          3.   Survival. Except as otherwise provided herein, the terms and
conditions of the Employment Agreement shall remain in full force and effect.
Notwithstanding the provision of Section 8(d) of the Employment Agreement,
nothing herein or hereby shall

be deemed or have the effect of a material breach of the Employment Agreement or
otherwise constitute an "Involuntary Termination."

          4.   Counterparts. This Second Addendum may be executed in
counterparts, each of which shall be deemed an original, but both of which
together will constitute one and the same instrument.

          IN WITNESS WHEREOF, each of the parties has executed this Second
Addendum, in the case of the Company, by its duly authorized officer or
representative, as of the day and year first above written.
