                                  (Unaudited)
A. Basis Of Presentation

   The condensed consolidated financial statements include the accounts of PRI
Automation, Inc. and its wholly-owned subsidiaries (collectively, the
"Company"). All significant intercompany transactions and balances have been
eliminated.

   The condensed consolidated financial statements are unaudited. However, in
the opinion of management, all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of such information have been
made. The results for interim periods are not necessarily indicative of the
results for the entire year. The condensed consolidated financial statements
should be read in connection with the audited consolidated financial statements
of the Company for the year ended September 30, 1997 included in its Form 10-K,
filed with the Securities and Exchange Commission.

   In January 1998 the Company acquired Equipe Technologies, Inc., E-Machine,
Inc., and Equipe Japan Ltd. (collectively, "Equipe"). On May 19, 1998 the
Company acquired Chiptronix Handling Systems GmbH ("Chiptronix"). The
acquisitions of Equipe and Chiptronix both were accounted for using the pooling
of interests method of accounting. All prior period historical condensed
consolidated financial statements presented herein have been restated to include
the financial position, results of operations, and cash flows of Equipe. The
Company has not restated its financial statements for the acquisition of
Chiptronix due to immateriality (see Note E).

   For interim reporting purposes, the Company closes its first three fiscal
quarters on the Sunday nearest the last day of December, March and June in each
year. The Company's fiscal year ends on the last day of September.

D. Earnings Per Share

   The Company has adopted Statement of Financial Accounting Standard ("SFAS")
No. 128, "Earnings Per Share," which specifies the computation, presentation and
disclosure requirements for net income (loss) per common share. Basic net income
(loss) per common share is computed based on the weighted average number of
common shares outstanding during the period.  Diluted net income (loss) per
common share gives effect to all dilutive potential common shares outstanding
during the period.  Under SFAS No. 128, the computation of diluted net income
per common share does not assume the issuance of common shares that have an
antidilutive effect on net income per common share.  All net income per common
share amounts have been restated for periods prior to the quarter ended December
28, 1997.  A reconciliation between basic and diluted earnings per share is as
follows (in thousands, except per share data):

    Options to purchase 595,944 and 790,737 shares of common stock were
outstanding for the three and nine months ended June 28, 1998, respectively, but
were not included in the computation of diluted net loss per common share
because the Company is in a loss position and, the inclusion of such shares
therefore, would be antidilutive. Options to purchase 11,918 and 9,253 shares of
common stock were outstanding for the three and nine month periods ended June
29, 1997 but were not included in the computation of diluted net income per
common share because the options' exercise prices were greater than the average
market price of the common shares and therefore, would be antidilutive under the
treasury stock method.

E. Acquisitions

   On October 29, 1997 the Company acquired Interval Logic Corporation ("ILC"),
a California corporation, for aggregate consideration of 111,258 shares of the
Company's common stock. In addition, the Company issued or assumed options to
purchase an aggregate of 199,170 shares of the Company's common stock. ILC was
formed in 1995 to develop advanced, high-perfomance planning and scheduling
software solutions for the semiconductor industry. The value of the transaction
is $8.5 million including approximately $600,000 of expenses related to the
acquisition. The transaction was accounted for as a purchase. The purchase price
was allocated to the tangible and intangible assets of ILC based on the
estimated fair value of those assets using a risk-adjusted discounted cash flow
approach. Specifically, the purchased technology was evaluated through extensive
interviews and analysis of data concerning the state of the technology and was
deemed to be in-process research and development because the Company needed to
make significant further investments to complete development of the technology,
to integrate it with the Company's existing products including the "Transnet"
product line and to enable it to meet expected customer requirements. The
Company recognized a charge of $8,417,000 for the purchase of in-process
research and development in October 1997. Pro forma results are not presented
due to immateriality.

   On January 22, 1998 the Company acquired Equipe Technologies, Inc., E-
Machine, Inc. and Equipe Japan Ltd., (collectively, "Equipe"). Equipe is a
leading worldwide developer, manufacturer, and supplier of wafer and substrate
handling robots, pre-aligners and controllers to semiconductor process tool
manufacturers. The Company issued 4,364,016 shares of common stock in exchange
for all of the outstanding stock of Equipe. The business combination was
accounted for as a pooling of interests. The accompanying condensed consolidated
financial statements for periods prior to the merger have been restated to
present the combined operations of the merged companies. Significant
intercompany transactions for the Equipe companies prior to the period in which
the business combination occurred have been eliminated from the accompanying
financial statements. Direct acquisition costs of $4,490,000, primarily relating
to legal, investment banking, and accounting fees, have been charged against
results of operations for the nine months ended June 28, 1998.

   The following information presents certain statement of operations data (in
thousands) of the Company and Equipe for the periods prior to the acquisition:

  On May 19, 1998, the Company acquired Chiptronix Handling Systems GmbH
("Chiptronix"), a Switzerland corporation, for aggregate consideration of
105,000 shares of the Company's common stock.  Chiptronix is the European
distributor of Equipe products.  The business combination was accounted for as a
pooling of interests.  However, as the financial position and results of
operations of Chiptronix are immaterial to the financial position and results of
operations of the Company on a consolidated basis, no prior period financial
amounts have been restated.  In accordance with this business combination, the
Company has acquired the net assets of Chiptronix, including its retained
deficit of $1,556,000 as of March 29, 1998 and this amount is included in the
changes to stockholders' equity for the three months ended June 28, 1998.  The
results of operations for the quarter ended June 28, 1998 of Chiptronix have
been consolidated into the accompanying financial statements of the Company.

F.  Special Charges

  For the third quarter of fiscal 1998, the Company recorded a pre-tax charge
against earnings of $2,140,000, which is included in operating expenses for the
quarter, associated with the restructuring plan announced by the Company on July
13, 1998.  The charge includes provisions for severance compensation of $1.1
million resulting from reductions of approximately 161 personnel, costs of
$320,000 relating to reduction in facilities space at four locations, provisions
for doubtful accounts of $500,000 and $220,000 for other contingencies.  The
Company also recorded a pre-tax charge of $4,900,000 against earnings, which is
included in cost of revenue for the third quarter of fiscal 1998, for the write-
down of inventories to their net realizable values.

  For the second quarter of fiscal year 1998, the Company recorded a non-
recurring charge of $2,323,000 against results of operations for restructuring
costs. The Company restructured its operations by consolidating its business
unit structure into a more centralized functional organization as a result of
the Equipe acquisition.  This pre-tax charge included costs of approximately
$1,723,000 related to two facilities which are anticipated to be idle until
April 1999 and approximately $600,000 for severance.  As of June 28, 1998,
facilities expenses charged  against this reserve amounted to $870,000 and the
Company expects to pay the balance of $853,000 through April 1999.
Additionally, as of June 28, 1998 $357,000 was charged against the restructuring
liability for severance payments to 83 former personnel and the Company expects
the balance to be paid by December 1998.

G.  INCOME TAXES

  The effective tax rate for the three and nine months ended June 28, 1998 was
(35.0%) and (13.2%) as compared to 25.0% and 26.1 %, respectively, for the
corresponding periods in fiscal 1997.  The effective tax benefit for the nine-
month period ended June 28, 1998 was unfavorably impacted by the charges for
acquired in-process research and development and merger and other non-recurring
costs which are not fully deductible for tax purposes.  This unfavorable impact
was partially offset by the impact of Equipe Technologies, Inc. and E-machine,
Inc., which were both subchapter S-corporations for federal income tax purposes
for the three months ended December 28, 1997.  The tax rate, exclusive of the
acquired in-process research and development charge, merger costs and other
special charges, for the three and nine months ended June 28, 1998 would have
been (35.0%) and 19.6% as compared to 25.0% and 26.1% for the corresponding
periods in fiscal 1997.  The changes in the effective tax rates excluding these
special charges, for the three and nine months ended June 28, 1998 as compared
with the corresponding periods in fiscal 1997 are attributable to the fact that
prior to January 1, 1998 Equipe Technologies, Inc. and E-Machine, Inc. were not
subject to federal income tax due to S-corporation status.

H.  JOINT VENTURE

  Effective June 1, 1998 the Company entered into a Korean joint venture with
Chung Song System Co., Ltd. ("CSSC") and Shinsung Engineering Co. Ltd. ("SEC")
to distribute the Company's products and services in Korea.  CSSC and SEC are in
the business of development and marketing of products and services for the
semiconductor industry.  Under the terms of the agreement, the Company owns 80%
of the joint venture and CSSC and SEC each own 10% of the joint venture.  The
Company and its partners have committed to invest 2.6 billion Korean Won of
capital in the joint venture over a two-year period beginning June 1, 1998.

I.  NEW ACCOUNTING PRONOUNCEMENTS

  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities."  This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities.  The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value.  The accounting for changes in fair value, gains or
losses, depends on the intended use of the derivative and its resulting
designation.  The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999.  The Company will adopt SFAS 133 by October 1,
1999.  The Company is evaluating SFAS 133 to determine its impact on its
consolidated financial statements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Certain Factors That May Affect Future Results

  From time to time, information provided by the Company, statements made by its
employees or information included in its filings with the Securities and
Exchange Commission may contain statements which are not historical facts but
which are "forward-looking statements" which involve risks and uncertainties.
In particular, statements in "Management's Discussion and Analysis of Financial
Condition and Results of Operations," relating to the Company's revenue and
expense levels, profitability and the sufficiency of capital to meet working
capital and capital expenditures requirements, may be forward-looking
statements.  The words "expect," "anticipate," "internal," "plan," "believe,"
"seek," "estimate" and similar expressions also are intended to identify such
forward-looking statements.  This Report also contains other forward-looking
statements.  Such statements are not guarantees of future performance, and
involve certain risks, uncertainties and assumptions that could cause the
Company's future results to differ materially from those expressed in any
forward-looking statements made by or on behalf of the Company.  Many of such
factors are beyond the Company's ability to control or predict.  Readers are
accordingly cautioned not to place undue reliance on forward-looking statements.
The Company disclaims any intent or obligation to update publicly any forward-
looking statements whether in response to new information, future events or
otherwise.  Important factors that may cause the Company's actual results to
differ from such forward-looking statements include, but are not limited to, the
factors discussed below.

  The Company's future results are subject to substantial risks and
uncertainties.  The Company's business and results of operations depend in
significant part upon capital expenditures from manufacturers of semiconductors,
which in turn depend upon the current and anticipated market demand for
semiconductors and products incorporating semiconductors.  Historically, the
semiconductor industry has been highly cyclical with recurring periods of over-
supply, which often have had a severe effect on the semiconductor industry's
demand for capital expenditures, including systems manufactured and marketed by
the Company.  The Company believes that the markets for newer generations of
semiconductors will also be subject to similar fluctuations.  Also, the recent
high rate of technical innovation and resulting improvements in the performance
and price of semiconductor devices, which have driven much of the demand for the
Company's products, could slow, or encounter limits, in the future.  In
addition, any other factor adversely affecting the semiconductor industry or
particular segments within the semiconductor industry may adversely effect the
Company's business, financial condition and operating results.

  The current financial uncertainty within the economies of certain Asian
countries has adversely affected, and may continue to adversely affect, the
worldwide semiconductor industry and the Company.  These effects have included
and could include delay or cancellation of orders from customers in these
countries.  Additional risks and uncertainties include: competitive pressures on
selling prices; inventory management, including suppliers' ability to meet the
Company's needs in a timely manner; the timing and cancellation of customer
orders; changes in product mix; the Company's ability to introduce new products
and technologies on a timely basis; the Company's ability to increase its
manufacturing capacity to meet increased demand while maintaining satisfactory
levels of product quality, service levels, and timeliness of deliveries; rapid
technological change and  introduction of products and technologies by the
Company's competitors; market acceptance of the Company's and its competitors'
products; the level of orders received which can be shipped in a quarter, the
timing of investments in engineering and development, the Company's ability to
absorb and manage acquisitions, and risks associated with doing business in Asia
and Europe.  As a result of the foregoing and other factors, the Company may

                                       12
<PAGE>
 
experience material fluctuations in future operating results on a quarterly or
annual basis which could materially and adversely affect its business, financial
condition, operating results and stock price.

RESULTS OF OPERATIONS

     On January 22, 1998 the Company acquired Equipe Technologies, Inc., 
E-Machine, Inc. and Equipe Japan Ltd., (collectively, "Equipe").  Equipe is a
leading worldwide developer, manufacturer, and supplier of wafer-handling
robots, pre-aligners and controllers to semiconductor process tool
manufacturers.  The business combination was accounted for as a pooling of
interests.  The financial results of the Company for fiscal periods prior to the
second quarter of fiscal 1998 have been restated to reflect the results of
operations for the combined entities.

     Revenue:   Net revenue for the three and nine months ended June 28, 1998
was $38.3 million and $150.6 million, respectively, a decrease of 31.8% and an
increase of 0.7%, respectively, over the corresponding periods in fiscal 1997.
Net revenue for the three months ended June 28, 1998 as compared to the
corresponding period in fiscal 1997 was adversely affected by the current
downturn in the semiconductor industry resulting in decreased demand for the
Company's products.  Net export sales to customers for the three and nine months
ended June 28, 1998 were $15.9 million and $51.7 million, respectively, compared
to $25.9 million and $62.8 million, respectively, for the corresponding periods
in fiscal 1997.  Net export sales for the three months and nine months ended
June 28, 1998 accounted for 41.6% and 34.4% of net revenue, respectively, as
compared to 46.1% and 42.0%, respectively, of net revenue for the corresponding
periods in fiscal 1997.

     Gross profit: The gross profit margin for the three and nine months ended
June 28, 1998 was 22.8% and 38.1% of net revenue, respectively, as compared to
44.7% and 44.3% of net revenue for the corresponding periods in fiscal 1997. The
decline in gross profit margin is partially due to a reduced level of equipment
sales and an unfavorable absorption of fixed manufacturing costs. Additionally,
a provision of $4.9 million, to reduce inventories to their net realizable
values, in the third quarter of fiscal 1998 reduced the gross profit margin by
12.8% of net revenue for this fiscal quarter and by 3.3% for the nine months
ended June 29, 1998.

     Research and development:  Research and development expenses for the three
and nine months ended June 28, 1998 were $9.5 million and $28.2 million,
respectively, representing 24.8% and 18.7% of net revenue, respectively,
compared to $7.3 million and $20.3 million, representing 12.9% and 13.5% of net
revenue for the corresponding periods in fiscal 1997.  The increases in research
and development expenses are attributable to the Company's ongoing investment in
next-generation wafer flow automation systems for end user and OEM customers.
This includes material control and scheduling software, atmospheric and vacuum
wafer-handling systems and automated material handling systems for advanced
200mm fabs and, in the near future, 300mm pilot lines.

     Selling, general and administrative:  Selling, general and administrative
expenses for the three and nine months ended June 28, 1998 were $9.0 million and
$27.3 million, respectively, representing 23.4% and 18.1% of net revenue,
compared to $8.9 million and $22.0 million, representing 15.9% and 14.7% of net
revenue for the corresponding periods in fiscal 1997.  The increase in selling,
general and administrative expenses occurred in the first and second quarters of
fiscal 1998 and is attributable to investments in general and administrative
infrastructure, management, and marketing and sales support.

  Acquired in-process research and development:  In October 1997, the Company
acquired Interval Logic Corporation ("ILC") in a transaction valued at $8.5
million, accounted for as a purchase.  ILC was formed in 1995 to develop
advanced high-performance planning and scheduling software solutions for the
semiconductor industry.  At the time of the acquisition, the purchase price was
allocated to the tangible and intangible assets of ILC based on the fair market
value of those assets using a risk-adjusted 

                                       13
<PAGE>
 
discounted cash flow approach. Specifically, the purchased technology was
evaluated through extensive interviews and analysis of data concerning the state
of the technology and was deemed to be in-process research and development
because of the Company's need to make significant further investments to
complete development of the technology, to integrate it with the Company's
existing products including the "Transnet" product line and to enable it to meet
expected customer requirements. The Company recognized a charge of $8.4 million
for the purchase of in-process research and development in October 1997.

  Merger costs and special charges:  The Company recorded a pre-tax charge of
approximately $2.1 million against earnings for the three months ended June 28,
1998, associated with the Company's restructuring plan announced July 13, 1998.
The charge includes provisions for severance compensation of $1.1 million to
reduce personnel by approximately 161, costs of $320,000 relating to reduction
in facilities space at four locations, provisions for doubtful accounts of
$500,000 and $220,000 for other contingencies.  In the second quarter of fiscal
1998 ended March 29, 1998, the Company took a $4.5 million charge against
earnings related to the January 22, 1998 acquisition of Equipe.  Additionally,
in the second quarter of fiscal 1998 the Company, to restructure its business
units, took a $2.3 million charge against earnings for non-recurring costs,
which included pre-tax costs of $1.7 million for two idle facilities and
$600,000 for the severance of approximately 83 administrative and operations
personnel.

  Other (expense) income, net:  Other (expense) income, net for the three and
nine months ended June 28, 1998 was ($105,000) and $467,000, respectively, as
compared to $257,000 and $820,000 for the corresponding periods in fiscal 1997.
Interest income for the three and nine months ended June 28, 1998 was $342,000
and $1.1 million respectively, as compared to $261,000 and $856,000 for the
corresponding periods in fiscal 1997.  Interest expense for the three and nine
months ended June 28, 1998 was ($15,000) and ($24,000), respectively, as
compared to ($6,000) and ($15,000) for the corresponding periods in fiscal 1997.
In addition, non-interest other (expenses) for the three and nine months ended
June 28, 1998 amounted to ($432,000) and ($616,000).

  Income tax (benefit) provision:  The effective tax rate for the three and nine
months ended June 28, 1998 was (35.0%) and (13.2%) as compared to 25.0% and 
26.1%, respectively, for the corresponding periods in fiscal 1997. The effective
tax benefit for the nine-month period ended June 28, 1998 was unfavorably
impacted by the charges for acquired in-process research and development and
merger and other non-recurring costs which are not fully deductible for tax
purposes. This unfavorable impact was partially offset by the impact of Equipe
Technologies, Inc. and E-Machine, Inc., which were both subchapter 
S-corporations for federal income tax purposes for the three months ended
December 28, 1997. The tax rate, exclusive of the acquired in-process research
and development charge, merger costs and other special charges, for the three
and nine months ended June 28, 1998 would have been (35.0%) and 19.6% as
compared to 25.0% and 26.1% for the corresponding periods in fiscal 1997. The
changes in the effective tax rates excluding these special charges, for the
three and nine months ended June 28, 1998 as compared to the corresponding
periods in fiscal 1997 are attributable to the fact that prior to January 1,
1998 Equipe Technologies, Inc. and E-Machine, Inc. were not subject to federal
income tax due to S-corporation status.

  Net (loss) income:  The net loss for the three and nine months ended June 28,
1998 was $7.8 million and $13.0 million, respectively, as compared to net income
of $6.9 million and $18.3 million for the corresponding periods in fiscal 1997.
Excluding special charges of $4.6 million, post-tax, the net loss for the three
months ended June 28, 1998 would have been $3.2 million, $0.16 net loss per
common share, as compared to net income of $6.9 million, $0.34 net income per
diluted common share, in the same period in fiscal year 1997.  Net income in the
nine months ended June 28, 1998, excluding the acquired in-process research and
development costs, the Equipe acquisition merger costs and other special charges

                                       14
<PAGE>
 
recorded by the Company, would have been $5.9 million, $0.29 per diluted common
share, as compared with net income of $18.3 million, $0.91 per diluted common
share, for the corresponding period in fiscal year 1997.

LIQUIDITY AND CAPITAL RESOURCES

  Since its inception, the Company has funded its operations primarily through
private equity financings, bank lines of credit, public stock offerings in
October 1994 and July 1995 and cash generated from operations.

  As of June 28, 1998 the Company had working capital of $94.5 million,
including cash and cash equivalents of $34.5 million and short-term marketable
securities of $1.3 million.  Additionally, the Company had $3.3 million of non-
current marketable securities at June 28, 1998.

  The total increase in cash and cash equivalents for the nine months ended June
28, 1998 was $6.9 million.  Net cash provided by operating activities for the
nine months ended June 28, 1998 was $21.2 million, compared to $3.3 million for
the corresponding period in fiscal 1997.  The net cash provided by operating
activities for the nine months ended June 28, 1998 was primarily attributable to
the net loss which, after adjusting for non-cash items, provided $1.7 million,
and to decreases in trade accounts receivable of $38.7 and billings in excess of
revenues and customer advances of $1.6 million.  The sources of cash were offset
partially by cash used to increase contracts in progress by $2.6 million,
inventories by $3.1 million, other assets by $5.5 million, and to decrease
accounts payable and other liabilities by $9.7 million.  For the nine months
ended June 29, 1997, net cash provided by operating activities was primarily
attributable to net income of $23.4 million after adjusting for non-cash
expenses, increases in accounts payable of $2.6 million and in accrued expenses
and other liabilities of $6.4 million, offset in part by increases in trade
accounts receivable of $15.0 million, in inventories of $8.9 million, in
contracts in progress of $2.1 million, and in other assets of $2.0 million.

  Net cash used in investing activities for the nine months ended June 28, 1998
was $11.0 million as compared to $4.7 million of net cash provided by investing
activities for the corresponding period in fiscal 1997. Net cash used in
investing activities for the nine months ended June 28, 1998 was primarily
attributable to the purchase of property and equipment of $9.8 million and the
purchases, net of sales and maturities, of marketable securities of $1.5
million.  Net cash provided by investing activities for the nine months ended
June 29, 1997 was attributable to the net purchase, sales and maturities of
marketable securities of $9.0 million, offset partially by the purchase of fixed
assets of $4.3 million.

  Net cash used in financing activities for the nine months ended June 28, 1998
was $3.2 million as compared to $5.1 million for the corresponding period in
fiscal 1997. Net cash used in financing activities for the nine months ended
June 28, 1998 and June 29, 1997 was primarily attributable to normal dividend
distributions of $4.5 million and $6.6 million, respectively, to shareholders of
Equipe Technologies and E-Machine, Inc. prior to their acquisition by the
Company. Both of these Equipe entities operated as S-corporations prior to the
merger with the Company. In addition, net cash used in financing activities for
the nine months ended June 29, 1997 included repayments of short-term bank
borrowings of $900,000. These uses of cash were offset partially by proceeds
from the exercise of stock options and from proceeds of the Company's Employee
Stock Purchase Plan.

   At June 28, 1998, the Company had a revolving credit agreement with The Chase
Manhattan Bank (the "Bank"). The revolving credit facility enables the Company
to borrow up to $20,000,000 on an unsecured basis.  Outstanding revolving credit
loans bear interest, at the Company's option, at the 30, 60 or 90 day LIBOR rate
plus a credit spread or at the effective prime rate.  At June 28, 1998, the
LIBOR 

                                       15
<PAGE>
 
borrowing rate would have been 6.75% and the prime rate was 8.5%. The ability of
the Company to effect borrowings under the revolving credit facility is
conditioned upon the meeting of certain financial criteria. The revolving credit
agreement expires on June 16, 2000. As of June 28, 1998, the Company had no
borrowings under this credit agreement.

   The Company believes that existing cash and investment balances and funds
available under its existing lines of credit will be sufficient to meet the
Company's cash requirements to fund operations and expected capital expenditures
during the next twelve months.

NEW ACCOUNTING PRONOUNCEMENTS

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities."  This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities.  The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value.  The accounting for changes in fair value, gains or
losses, depends on the intended use of the derivative and its resulting
designation.  The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999.  The Company will adopt SFAS 133 by October 1,
1999.  The Company is evaluating SFAS 133 to determine its impact on its
consolidated financial statements.

YEAR 2000

  Computer systems and software products that were designed to accept entries of
only two digits in the "year" date code field may be unable to properly process
date information beyond the year 1999. Inability of the Company's products to
process these dates could have a material adverse effect on its business. The
Company has established a centrally coordinated project team, including
representatives of each of the Company's divisions, to determine the Year 2000
readiness of the Company's products, business processes and systems. The Company
has reviewed all equipment and software currently being marketed or already
installed at customer sites for Year 2000 compliance. The Company expects to
complete all internal and field testing and upgrades of current and installed
products by the end of calendar 1998. The Company cannot presently estimate the
total cost of this testing and upgrade process but does not expect it to be
material. The Company is also assessing its internal systems, including business
information systems, systems utilized in its manufacturing and service
operations, and systems providing electronic interfaces between the Company and
its business associates and customers, to ensure the Company's operations are
not interrupted by Year 2000 issues. The Company expects to have addressed all
internal Year 2000 issues identified in this process by the end of calendar
1998. The Company is also working closely with suppliers and other third parties
upon which it is dependent to determine the extent of their Year 2000
compliance. Based on its investigation to date the Company does not expect the
total cost of its Year 2000 assessment and remediation program to have a
material adverse effect on the Company's business, results of operations or
financial condition.

     any damage caused thereby, nor shall this Sublease be void or voidable but
     Sublessee shall not be liable for Rent until such time as Sublessor offers
     to deliver possession of the Subleased Premises to Sublessee, but the term
     hereof shall not be extended by such delay. If Sublessee, with Sublessor's
     consent, takes possession prior to commencement of the term, Sublessee
     shall do so subject to all the covenants and conditions hereof and shall
     pay Rent for the period ending with the commencement of the term at the
     same rental as that prescribed for the first month of the term prorated at

8.  Signage:
All rights to signage shall be subject to the Master Lease.

Upon full execution of the Sublease Agreement, Sublessee shall have early access

10. Broker Fee and Representation:
Within thirty (30) days of the Sublease Agreement, Sublessor shall pay Cornish &

11. Compliance With Nondiscrimination Regulations:
It is understood that it is illegal for Sublessor to refuse to display or
sublease the Subleased Premises, or to assign, surrender or sell the Master
Lease, to any person because of race, color, religion, national origin, sex,
sexual orientation, marital status or disability.

12. Toxic Contamination Disclosure:
Sublessor and Sublessee each acknowledge that they have been advised that
numerous federal, state, and/or local laws, ordinances and regulations ("Laws")
affect the existence and removal, storage, disposal, leakage of and
contamination by materials designated as hazardous or toxic ("Toxics"). Many
materials, some utilized in everyday business activities and property
maintenance, are designated as hazardous or toxic.

Some of the Laws require that Toxics be removed or cleaned up by landowners,
future landowners or former landowners without regard to whether the party
required to pay for "clean up" caused the contamination, owned the property at
the time the contamination occurred or even knew about the contamination. Some
items, such as asbestos or PCBs, which were legal when installed, now are
classified as Toxics, and are subject to removal requirements. Civil lawsuits
for damages resulting from Toxics may be filed by third parties in certain
circumstances.

Sublessor and Sublessee each acknowledge that Broker has no specific expertise
with respect to environmental assessment or physical condition of the Subleased
Premises, including, but not limited to, matters relating to: (i) problems which
may be posed by the presence or disposal of hazardous or toxic substances on or
from the Subleased Premises, (ii) problems which may be posed by the Subleased
Premises being within the Special Studies Zone as designated under the
Alquist-Priolo Special Studies Zone Act (Earthquake Zones), Section 2621-2630,
inclusive of California Public Resources Code, and (iii) problems which may be
posed by the Subleased Premises being within a HUD Flood Zone as set forth in
the U.S. Department of Housing and Urban Development "Special Flood Zone Area
Maps," as applicable.


                                                                        rev 7/95

                                   SUBLEASE
================================================================================

Sublessor and Sublessee each acknowledge that Broker has not made an independent
investigation or determination of the physical or environmental condition of the
Subleased Premises, including, but not limited to, the existence or nonexistence
of any underground tanks, sumps, piping, toxic or hazardous substances on the
Subleased Premises. Sublessee agrees that it will rely solely upon its own
investigation and/or the investigation of professionals retained by it or
Sublessor, and neither Sublessor nor Sublessee shall rely upon Broker to
determine the physical and environmental condition of the Subleased Premises or
to determine whether, to what extent or in what manner, such condition must be
disclosed to potential sublessees, assignees, purchasers or other interested
parties.

                  THE PARTIES ENTER this Agreement on the basis of the following
facts, intentions and understandings:

                  A. Landlord leases to Tenant, and Tenant leases from Landlord,

- ---------
                  B. Tenant and Subtenant entered a sublease ("Sublease") dated
March 18, 1998, a copy of which is attached hereto as Exhibit B, whereby Tenant
                                                      ---------
proposes to sublease to Subtenant and Subtenant proposes to sublease from Tenant
the Premises.

                  C. The terms of the Master Lease require the written consent
of Landlord as a condition precedent to the Sublease.

                  D. Guarantor has executed and delivered to Landlord that
certain Guarantee dated as of December 15, 1994, pursuant to which Guarantor
guarantied the obligations of Tenant under the Master Lease.

                  E. Tenant and Subtenant now desire to amend the Sublease and
Landlord and Tenant now desire to amend the Lease as provided herein. In
addition, Landlord hereby grants its consent to the Sublease on the terms and

                  NOW THEREFORE, IN CONSIDERATION of the mutual covenants and
promises of the parties, the parties hereto agree as follows:

                  1. Consent. Landlord hereby consents to the Sublease subject

<PAGE>
 
                  2. Representations. Tenant hereby represents and warrants to
Landlord that:

                     a.  Master Lease. The Master Lease attached hereto as
                         ------------
Exhibit A is a true and correct copy of the Master Lease, and there exist no
- ---------
amendments, modifications or extensions of or to the Master Lease (except as
included in the Master Lease attached hereto), and the Master Lease is now in
full force and effect, and

                     b.  No Offsets. There exist no defenses or offsets to
                         ----------
enforcement of the Master Lease by Landlord, and Landlord is not, as of the date
of Tenant's execution hereof, in default in the performance of the Master Lease,
nor has Landlord committed any breach thereof, nor has any event occurred which,
with the passage of time, or the giving of notice, or both, would constitute a
default or breach by Landlord.

                  3. Subordinate. The Sublease shall be subject and subordinate
                     -----------
to the Master Lease and all of the Master Lease's provisions, covenants and
conditions. In case of any conflict between the provisions of the Master Lease
and the provisions of the Sublease, the provisions of the Master Lease shall
prevail unaffected by the Sublease. Subtenant shall comply with the terms and
conditions of the Master Lease to the extent applicable to the use and occupancy
of the Premises. Any breach of the Master Lease by either Tenant or Subtenant
shall entitle Landlord to all the rights and remedies provided in the Master
Lease in the event of a breach, and any other available remedy, against both
Tenant and Subtenant.

                  4. No Ratification. This Agreement shall not operate as a
                     ---------------
consent to, approval of, or ratification by Landlord of any of the provisions of
the Sublease and Landlord shall not be bound or estopped in any way by the
provisions of the Sublease.

                  5. No Waiver. This Agreement shall not be construed to modify,
                     ---------
waive or affect (i) any present or future breach or default on the part of
Tenant under the Master Lease; (ii) any of the provisions, covenants, or
conditions in the Master Lease (except as provided in Section 15); (iii) any of
Tenant's obligations under the Master Lease; or (iv) any rights or remedies of
Landlord under the Master Lease or to enlarge or increase Landlord's obligations
or Tenant's rights under the Master Lease.

                  6. Not Assignable. This Agreement is personal to Tenant,
                     --------------
Guarantor and Subtenant and may not be assigned by Tenant, Guarantor or
Subtenant. Any attempted assignment in violation of this section shall be void.

                  7. No Release. Neither the Sublease nor this Agreement shall
                     ----------
release or discharge Tenant from any liability under the Master Lease and Tenant
shall remain liable and responsible for the full performance and observance of
all of the provisions, covenants and conditions set forth in the Master Lease on
the part of Tenant to be performed and observed. The breach or violation of any
provision of the Master Lease by Subtenant shall constitute a default by Tenant
in fulfilling such provision. Tenant shall indemnify Landlord against any

                                      2.
<PAGE>
 
loss, cost or expense, including attorneys' fees or costs, which arise by virtue
of the Sublease or Subtenant's occupancy of the Premises.

                  8.  Consent to Subsequent Sublease. This Agreement by Landlord
                      ------------------------------
shall not be construed as a consent by Landlord to any future assignment or
subletting either by Tenant or Subtenant. The Sublease may not be assigned,
renewed or extended, nor shall the Premises, or any part thereof, be further
sublet without the prior written consent of Landlord in each instance.

                  9.  Termination. Upon the expiration of the term or earlier
                      -----------
termination of the Master Lease, or upon the surrender of the Premises by Tenant
to Landlord, except as provided in Section 10 below, the Sublease shall
terminate as of the effective date ("Termination Date") of such expiration,
termination or surrender, and Subtenant shall vacate the Premises on or before
the Termination Date. Pursuant to Section 8.1 of the Master Lease, Tenant shall
surrender the Premises to Landlord at the expiration or earlier termination of
the Master Lease in the same condition as when leased, reasonable wear and tear,
damage by fire or other insured casualty excepted. Subtenant shall cooperate
with Tenant in connection with Tenant's performance of its obligations pursuant
to this Section 9. If Tenant fails to surrender the Premises to Landlord in the
condition provided above, Tenant, at Landlord's election, shall be deemed to
have held over in the Premises (in accordance with Section 18.12 of the Master
Lease) until such time as Tenant completes Tenant's obligations under the Master
Lease with respect to the condition in which Tenant is required to surrender to
Landlord possession of the Premises to Landlord.

                  10. Landlord's Election. If the Master Lease expires or
                      -------------------
terminates during the term of the Sublease for any reason, or if Tenant shall
surrender the Master Lease to Landlord, Landlord may elect, in Landlord's sole
discretion, by delivering written notice to Subtenant not later than thirty (30)
days after the Termination Date, to continue the Sublease as a direct lease
between Landlord, as landlord, and Subtenant, as tenant, on the terms and
conditions of the Sublease for either (i) the remaining term of the Sublease or
(ii) such periodic tenancy as Landlord shall select, provided that in no event
shall initial period of the periodic tenancy be in excess of the remaining term
of the Sublease. Upon an election by Landlord pursuant to this section,
Subtenant shall attorn to Landlord. If Landlord elects to continue the Sublease,
in no event shall Landlord be (i) liable to Subtenant for any act or omission by
Tenant, (ii) subject to any offsets or defenses which Subtenant had or might
have against Tenant, (iii) bound by any rent or additional rent or any other
payment which Subtenant may have paid to Tenant, or (iv) bound by any amendment
to the Sublease not consented to in writing by Landlord.

                  11. Continuing Liability. Both Tenant and Subtenant shall be
                      --------------------
liable for all bills rendered by Landlord for charges incurred by or imposed
upon Subtenant for services rendered and materials supplied to the Premises. If
a separate submeter shall be installed to measure utilities furnished to the
Premises, then payment for such installation and the utilities so furnished
shall be made by Subtenant directly to Landlord as and when billed and the


                                      3.
<PAGE>
 
furnishing of such utilities shall be in accordance with and subject to all of
the applicable terms, covenants and conditions of the Master Lease.

                  12. Notices. All notices required to be given hereunder shall
                      -------
be in writing and mailed postage prepaid by certified or registered mail, return
receipt requested, or by personal delivery, addressed to Landlord, Tenant and
Subtenant at the address provided below, or at such other address as may be
designated by notice given in accordance with the provisions of this Section 12.

          including, without limitation, claims for damages based upon alleged
          breach of contract, but such failure will cause this Agreement to
          expire and have no further effect except for those provisions
          specified in Section 17.6 which will survive the termination or
          expiration of this Agreement. There are no other

          the following.

          encumber shares in the Company held by such shareholder without the
          prior written consent of the other shareholder. Any transfer in
          violation of Section 7 of this Agreement gives rise to an action for
          damages in the Company and in the shareholder not in violation of
          Section 7, and all such additional relief or remedies as may be
          provided for or permitted by South Korean law as of the date of the
          violation of Section 7.

     7.3  Since damages arising from a breach of the above mentioned obligations
          under this Section 7 may be difficult to determine with precision, the
          shareholders agree

                                       4

          that the shareholder who breaches the terms of this Section 7 shall
          pay to the other shareholder as liquidated damages a sum equivalent to
          twice the fair market value of the shares, as determined in Section
          8.5, sold, transferred or otherwise disposed of or twice the proceeds
          received by the breaching shareholder in the transaction whereby the
          breach occurred, whichever is greater. The shareholders agree that
          such liquidated damages are fair and reasonable and will be without
          prejudice to, and cumulative with other remedies provided by law or
          this Agreement.

     7.4  In the event of an involuntary transfer of shares in the Company held
          by PRI, CSSC or SEC, the shareholders will have the rights set forth
          in Section 8 of this Agreement.

     7.5  In subscribing to shares in the Company, PRI, CSSC and SEC each
          represent and warrant that: (i) such shares were acquired by such
          shareholder solely for such shareholder's own account and not with a
          view to, or for resale in connection with, the distribution or other
          disposition thereof; (ii) such shareholder is intimately familiar with
          the prospects of the Company and the significant risks associated with
          an investment in the shares of the Company; and (iii) an investment in
          such shares may not be liquidated by the holder thereof, even in an
          emergency.

     7.6  Any certificates evidencing PRI's, CSSC's or SEC's shares in the
          Company will bear the following legend, along with such security law
          legends as counsel for the Company may deem necessary or appropriate:

          offices during the Company's ordinary business hours. In performing
          any such audit, the relevant shareholder will maintain the
          confidentiality of all information obtained as a result of such audit,
          will use such information only for the purposes of enforcing rights
          hereunder and will conduct such audit in a manner that causes a
          minimum disruption to the business. The costs of any such audit will
          be borne by the shareholder requesting the audit.

     8.6  The remedies under this Section 8 will be in addition to, but not in
          lieu of, the remedies or relief as may be provided for or permitted
          under the South Korean laws, the Article of Incorporation or other
          provisions of this Agreement. In the event of any conflict between the
          provisions of this Section 8 and the provisions of any other Section
          of this Agreement, the provisions of this Section 8 will control.

                jointly by PRI and CSSC ("Fifth Director"). PRI, CSSC and SEC
                agree to vote all shares of the Company owned or controlled by
                them, and otherwise to use their respective best efforts, to
                elect directors as specified in the preceding sentence. The
                initial directors of the Company will be as follows. PRI
                designates Mitchell G. Tyson and Robert G. Postle as the PRI
                Directors. CSSC designates S.K. Suh as the CSSC Director. SEC
                designates Wan-Keun Lee as the SEC Director. PRI and CSSC
                jointly appoint Robert Holzel as the Fifth Director.

          9.1.2 The Company's Board of Directors (the "Board") will meet at
                least quarterly and at such locations as the Board may from time
                to time agree. The presence of at least one PRI Director and one
                CSSC or SEC Director will be required to constitute a quorum for
                the transaction of business. The Fifth Director must be present
                within the meaning of the Company's bylaws or other governing
                rules of procedure in order to vote, and the Fifth Director will
                be invited to attend every meeting and will be allowed to vote
                on all matters submitted to a vote at any meeting where the
                Fifth Director is present.

          9.1.3 The Chairman of the Board will be appointed by the vote of the
                Board. If

                                       8
<PAGE>
 
                the Chairman so appointed is unable to attend any meeting of the
                Board, then PRI will be entitled to appoint another Director to
                act as Chairman in his or her place at such meeting.

          9.1.4 All decisions of the Board will be by simple numerical majority
                of all of the Directors in office and will require a numerical
                majority of all of the Directors in office, except regarding
                Fundamental Board Issues, as hereinafter defined, which will
                require a four-fifths majority of all Directors. In the event
                that a required majority cannot be achieved on any material
                matter moved before the Board, and in the event the party moving
                the matter continues to desire a decision from the Board, then
                the party moving the matter will provide a notice of failure to
                achieve the required majority to the Fifth Director who will
                schedule at the first reasonable opportunity, and in no event
                more than thirty (30) days after receiving such notice a meeting
                of the Board at which all Directors will be required to attend
                and at which the matter may be moved for a second vote in the
                presence of all five Directors. In the event that the required
                majority of Directors is not achieved regarding any Fundamental
                Board Issue, either PRI, CSSC or SEC may by written notice to
                the other shareholders declare that a deadlock (a "Board
                Deadlock") exists and the procedure described in Section 9.5
                below will be followed.

          9.1.5 The Board will elect the General Manager or Representative
                Director of the Company. PRI will have the right, at its sole

                Officer, Statutory Auditor or other chief financial officer of
                the Company, however denominated.

          9.1.6 Subject to applicable law, the compensation of directors and

                        person, such person is related by kinship to the

     9.4  Shareholder Deadlock.

          9.4.1  In the event that PRI, CSSC and SEC fail to agree on any
                 Fundamental Shareholder Issue, either PRI, SEC, or CSSC may by
                 written notice to the other shareholders and to the Company
                 declare that a deadlock (a "Shareholders' Deadlock") exists.
                 Following the giving of any such notice, the parties and the
                 Company will follow the procedure set forth in Section 9.5 of
                 this Agreement.

     9.5  Rights on Deadlock.

          9.5.1  Upon (i) a declaration of a Shareholders' Deadlock in
                 accordance with Section 9.4 above, or (ii) a declaration of a
                 Board Deadlock in accordance with Section 9.1.4 above, the
                 following procedures will be followed. The shareholder
                 declaring the Deadlock will provide notice of such declaration
                 to the Fifth Director. At the earliest reasonable opportunity,
                 and in no event more than twenty (20) days after his or her
                 receipt of such notice, the Fifth Director will schedule a
                 meeting which must be attended in person by all Directors at a
                 commercially reasonable location within or without South Korea,
                 but in no event at the offices of CSSC, SEC, PRI or the
                 Company. At this meeting the Fifth Director, or a third party
                 appointed by the Fifth Director and approved by PRI, SEC, and
                 CSSC, will attempt to mediate a resolution to the Deadlock.
                 The mediation will follow any method or procedure chosen by the
                 Fifth Director or the appointed mediator except that the
                 mediation will terminate no more than seventy two (72) hours
                 after it commences and all costs associated with the mediation
                 will be divided and paid evenly by CSSC, PRI, and SEC. If the
                 mediation does not result in the resolution of the Deadlock,
                 then the Company will shut down and cease operations, liquidate
                 all of its assets, pay any debts or obligations, and distribute
                 any residual value to the shareholders on the basis of their
                 share holdings at the time of the distribution. The shut down,
                 liquidation, satisfaction of debts and obligations, and
                 distribution will be supervised by the Treasurer, Auditor or
                 other chief financial officer of the Company at the time of
                 Deadlock and will be carried on in a commercially reasonable
                 manner on a commercially reasonable schedule.

10.  Management of Operations.

     10.1 The day-to-day business of the Company will be managed by the
          Representative Director of the Company. The Representative Director of
          the Company will report and be accountable to the Board. The initial
          Representative Director will be Suh, who will serve for a term of one
          year from the Effective Date of this


                                      12
<PAGE>
 
          Agreement, or until he is removed or replaced. Thereafter, the
          Representative Director will be designated by the unanimous consent of
          the shareholders and will serve in accordance with resolutions adopted
          by the Board and the shareholders.

     10.2 In the event any person serving as Representative Director is unable
          to perform his or her duties as a Representative Director because of
          medical disability (as evidenced by a written opinion of a physician),
          the business of the Company will be managed jointly for up to sixty
          days by one PRI Director chosen by PRI and the CSSC Director. If an
          incumbent Representative Director continues to be disabled after 60
          days, the Board will appoint a new Representative Director by
          unanimous consent and each shareholder or such shareholder's duly
          authorized representative will vote its shares in favor of appointing
          the Representative Director and take all other action necessary to
          provide for such appointment.

     10.3 As often as necessary to keep the Board and the shareholders
          reasonably informed of material events, and in no event less than once
          each calendar month, the Representative Director will provide to the
          Directors and the shareholders a written report summarizing the
          material facts arising from or relating to the Company's operational
          performance since the last such written report. In addition to such
          other information as the Representative Director may include at his
          discretion such operational reports will include the following: (i)
          the operational plans of the Company and any changes thereto; (ii) the
          acquisition and allocation of operational resources, including human
          resources, office space, equipment and other non-monetary resources;
          (iii) the efforts of the Company to market and promote the products of
          PRI; (iv) material matters relating to third party disputes and
          litigation, government relations including all necessary permits and
          approvals, and public relations and public image; and (v) all quotes
          for the sale of PRI Products that have been made and remain
          outstanding.

11. Creation and Amendment of the Business Plan.

    11.1  The first act of the Representative Director of the Company will be to
          cooperate and work together with PRI to develop promptly a business
          plan for the Company, to be approved and agreed upon by all
          shareholders ("Business Plan"). The Business Plan will include a
          description of: the scope of work the parties expect to be undertaken
          by the Company; staffing, organization and management requirements;
          marketing plans; methods of operation of the Company, and; such other
          subjects as the Representative Directors may choose to include or the
          shareholders may require. The period covered by the initial Business
          Plan will be three (3) years.

     11.2 Within sixty (60) days of the end of each fiscal year, the
          Representative Director will prepare a revised Business Plan to be
          approved and agreed upon by all


                                      13
<PAGE>
 
          shareholders prior to the end of the next fiscal year. The revised
          Business Plan will include additional plans necessary to extend the
          plan for the next three years, and will include such other revisions
          as the Representative Director may suggest and the shareholders may
          agree upon.

     11.3 The Business Plan may be revised at any time but only with unanimous
          written consent of the shareholders. Unless he or she receives
          unanimous written permission to the contrary, the Representative
          Director will operate the Company by implementing the Business Plan.

12.  Financial Management and Reporting.

     12.1 The fiscal year of the Company will end on September 30 of each year.

     12.2 In addition to financial records maintained according to the
          requirements of applicable law, the Company will at all times keep
          records and books of account in which complete and correct entries
          will be made, in accordance with generally accepted accounting
          principles and practices adopted from time to time by the Company and
          utilized in the preparation of its annual audited financial
          statements. The Company will afford to each shareholder and its
          employees, counsel, accountants and other authorized representatives
          free and full access, at all reasonable times, to all its books,
          records and properties and to all its officers and other employees of
          the Company having responsibility for financial or accounting matters
          generally, for any reasonable purpose whatsoever. Each shareholder
          will use all reasonable efforts to maintain the confidentiality of any
          confidential and proprietary information so obtained by it that is not
          otherwise available.

                                      14
<PAGE>
 
     12.3 The Company will prepare and submit to all shareholders at least
          ninety days prior to the beginning of each fiscal year an annual
          budget for the next fiscal year, including, on an annual and quarterly
          basis, an operating plan, capital plan and staffing plan in the
          format, and with such detail, as the shareholders may reasonably
          request. These plans will be accepted as the budget for such fiscal
          year when they have been approved by the shareholders (the "Budget").
                                                                      ------
          The Budget will be reviewed by the Company no less frequently than
          quarterly. All proposed changes to and material deviations from the
          Budget will be submitted to the shareholders in advance of their
          adoption by the Company and will only be adopted by the Company after
          such changes or deviations are approved by all shareholders.

     12.4 The financial statements of the Company will be audited as of the end
          of each fiscal year by independent certified public accountants of
          established international reputation agreed upon in writing by the
          shareholders (the "Accountant"). The Company will pay the costs of
          each such audit. All questions of accounting will be determined by the
          Accountant based on generally accepted accounting principles, and the
          determination of any such questions by the Accountant will be
          conclusive.

     12.5 Unless otherwise agreed to by the shareholders in writing, the Company
          will furnish to each shareholder the following financial statements
          and other information:

          12.5.1 Within ten (10) days after the end of each month, an unaudited
                 financial report of the Company, which report will be prepared
                 in accordance with generally accepted accounting principles
                 consistently applied and which will include: (i) an income
                 statement for such month, together with a cumulative income
                 statement from the first day of the then-current fiscal quarter
                 and year; (ii) a comparison between the actual income

          any of them in exercising any right, power or privilege hereunder, and
          no course of dealing between the Company and the shareholders or any
          of them will operate as a waiver thereof, nor will any single or
          partial exercise of any right, power or privilege hereunder preclude
          the simultaneous or later exercise of any other right, power or
          privilege. In the event that any provision of this Agreement will be
          held invalid or unenforceable, the remaining provisions of this

          further the purposes of the Company and this Agreement.

          instruments, certificates, documents, and to provide such information

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

 
    2.1   The Commitment.
          -------------- 

          (a) Subject to the terms and conditions of this Credit Agreement, and
     relying upon the representations and warranties herein set forth, Bank
     agrees to make Credit Loans to Borrower, at any time and from time to time
     on or after the Effective Date and until and including the Expiration Date
     in an aggregate principal amount not exceeding at any one time outstanding
     the principal sum of the Commitment; provided, however, that the sum of (i)
     the outstanding aggregate amount of Loans (after giving effect to all
     amounts requested), (ii) the aggregate principal amount outstanding of any
     and all letters of credit and/or bankers acceptances issued by Bank for
     Borrower as account party, and (iii) the aggregate amount of any
     unreimbursed payments made by Bank pursuant to any letter of credit or
     bankers acceptance, shall not at any time exceed the Commitment.  Within
     that limit, Borrower may borrow, repay and reborrow on or after the
     Effective Date and until and including the Expiration Date, except as
     provided in this Credit Agreement.

          (b) Borrower may at any time and from time to time terminate or
     permanently reduce the Commitment by giving not less than ten (10) Business
     Days' prior written notice to such effect to Bank, provided that any
     partial reduction shall be in the aggregate amount of $500,000 or a
     multiple thereof and that Borrower shall prepay such part, if any, of the
     principal of the Credit Note then outstanding as may be in excess of the
     amount of the Commitment as so reduced.

          (c) Except as otherwise provided herein, all outstanding Credit Loans
     shall be repaid on the Expiration Date.

    2.2   The Credit Note.  The obligation of Borrower to repay all amounts

    2.3   Borrowing Procedure.
          ------------------- 

          (a) The following individuals may request Credit Loans: Stephen D.
     Allison, Joanne Shifres and Mitchell G. Tyson.  Any request for a Credit
     Loan may be oral (including telephonic) or written, but if oral shall be
     promptly confirmed in writing.  Bank shall be protected and held harmless
     by Borrower in acting upon any request for a Loan believed by it to have
     been genuine and to have been given by a proper Person.

          (b) The minimum amount of each Loan under this Part is as follows:

          (i) for Eurodollar Loans, in an amount at least equal to $100,000.00
          and shall be in an integral multiple of $100,000; and

          (ii) for Prime Rate Loans, no minimum amount.

          (c) Bank will credit the proceeds of each Credit Loan to Borrower's
     deposit account with Bank.

          (d) Bank will maintain records of the date and amount of each
     borrowing, the interest rate selected and the Interest Period therefor, and
     each principal payment under this Part and will make a statement of these
     records available to Borrower upon request.  Bank may endorse on the grid
     portion of the Credit Note the date and the amount of each borrowing
     obtained from Bank, the interest rate selected and the Interest Period
     therefor and the initials or other identifying symbol of the Person making
     the endorsement.

    2.4   Interest.
          -------- 

          (a) Borrower will pay to Bank interest on the unpaid principal amount
     of each Credit Loan made by Bank for the period commencing on the date of
     such Loan to but excluding the date such Loan shall be paid in full, at the
     following rates per annum:

          (i) During such periods such Loan is a Prime Rate Loan, the Prime Rate
          (as in effect from time to time).

          (ii) During such periods such Loan is a Eurodollar Loan, for each
          Interest Period relating thereto, the Eurodollar Base Rate for such
          Loan for such Interest Period plus the Applicable Margin.

          (b) Notwithstanding the foregoing, Borrower will pay to Bank interest
     at the applicable Post-Default Rate on any principal of any Credit Loan
     made by Bank, and (to the fullest extent permitted by law) on any other
     amount (other than interest) payable to Bank by Borrower hereunder or under
     the Credit Note, which shall not be paid in full when due (whether on the
     last day of the applicable Interest Period, on the Expiration Date, by
     acceleration or otherwise), for the period commencing on the due date
     thereof until the same is paid in full.
<PAGE>
 
                                       8



          (c) Accrued interest on each Credit Loan shall be payable (i) in the
     case of a Prime Rate, monthly on the Monthly Due Date, and (ii) in the case
     of a Eurodollar Loan, on the last day of each Interest Period therefor, and
     if such Interest Period is shorter than thirty (30) days, on the last day
     of the calendar month in which the Interest Period ends, except that
     interest payable at the Post-Default Rate shall be payable from time to
     time on demand of Bank.  Promptly after the determination of any interest
     rate provided for herein or any change therein, Bank shall notify Borrower
     thereof.

    2.5   Commitment Fee.  Borrower agrees to pay a commitment fee to Bank as a
          --------------                                                       
consideration for the Commitment.  The commitment fee shall be calculated at the
rate of one fifth of one percent (0.20%) per annum (based on a year of 365 days)
from the Effective Date, on the average daily unborrowed amount of Bank's
Commitment.  The commitment fee will be payable on each Quarterly Due Date and
on the Expiration Date, for the preceding period for which such fee has not been
paid.  After any and each permanent reduction of the Commitment by Borrower,
future commitment fees shall be calculated upon the Commitment of Bank as so
reduced.

    2.6   Facility Fee.  On the Effective Date, Borrower shall pay to Bank a
          ------------                                                      
facility fee in an amount equal to one quarter of one percent ( 0.25%) of the
Commitment as then in effect.

    2.7   Prepayment.  Borrower shall have the right to prepay Credit Loans at
          ----------                                                          
any time or from time to time, provided that:

          (a) Borrower shall give Bank notice of each such prepayment as
 provided in Part 4.6 hereof; and

          (b) Eurodollar Loans may be prepaid only on the last day of an 
   Interest Period for such Loans.

    2.8   Additional Costs.
          ---------------- 

          (a) Borrower shall pay to Bank from time to time such amounts as Bank
     may determine to be necessary to compensate it for any costs which the Bank
     determines are attributable to its making or maintaining any Eurodollar
     Loan under this Credit Agreement or its undertaking to make or maintain any
     such Loans hereunder, or any reduction in any amount receivable by Bank
     hereunder in respect of any such Loans or such undertaking (such increases
     in costs and reductions in amounts receivable being herein called
     "Additional Costs"), resulting from any regulatory change applicable to
     Bank which:  (i) changes the basis of taxation of any amounts payable to
     Bank under this Credit Agreement in respect of any of such Loans (other
     than federal and state taxes imposed on the net income of Bank on account
     of any of such Loans by the jurisdiction in which the Bank is located); or
     (ii) imposes or modifies any reserve, special deposit, deposit insurance or
     assessment, capital or similar requirements relating to any extensions of
     credit or other assets of, or any deposits with or other liabilities of,
     Bank (including any of such Loans or any deposits referred to in the
     definition of Eurodollar Base Rate); or (iii) imposes any other condition
     affecting this Credit Agreement (or any of such extensions of credit or
     liabilities). 
<PAGE>
 
                                       9


     Bank will notify Borrower of any event occurring after the
     date of this Credit Agreement which will entitle Bank to compensation
     pursuant to this Part as promptly as practicable after it obtains knowledge
     thereof and determines to request such compensation.  All payments required
     from Borrower hereunder shall be made within fifteen (15) days of
     Borrower's receipt of notice that such payments are due.

          (b) Without limiting the effect of the foregoing provisions of this
     Part, in the event that, by reason of any regulatory change applicable to
     Bank, Bank either (i) incurs Additional Costs based on or measured by the
     excess above a specified level of the amount of a category of deposits or
     other liabilities of Bank which includes deposits by reference to which the
     Eurodollar Base Rate is determined as provided in this Credit Agreement or
     a category of extensions of credit or other assets of Bank which includes
     Eurodollar Loans or (ii) becomes subject to restrictions on the amount of
     such a category of liabilities or assets which it may hold, then, if Bank
     so elects by notice to Borrower, the undertaking of Bank to make such
     Eurodollar Loans, or to renew the Eurodollar Base Rate or to convert any
     interest rate option to the Eurodollar Base Rate shall be suspended until
     the date such applicable regulatory change ceases to be in effect, and
     Borrower shall on the last day of the then current Interest Period for such
     affected outstanding Loans pay such Loans in accordance with this Credit
     Agreement.

          (c) Determinations and allocations by Bank for purposes of this Part
     of the effect of any applicable regulatory change on its costs of making or
     maintaining such Loans or on amounts receivable by it in respect of such
     Loans, and of the additional amounts required to compensate Bank in respect
     of any Additional Costs, shall be conclusive, provided that such
     determinations are made in good faith on a reasonable basis.

    2.9   Limitation on Types of Loans.  Anything herein to the contrary
          ----------------------------                                  
notwithstanding, if Bank determines (which determination shall be conclusive)
that the relevant rates of interest which are the basis of the Eurodollar Base
Rate do not adequately cover the cost to Bank of making or maintaining the
Eurodollar Loans, then Bank shall give Borrower prompt notice thereof, and so
long as such condition remains in effect, Bank shall be under no obligation to
make such Loans and Borrower shall, on the last day(s) of the then current
Interest Period(s) for the outstanding Loans of the affected type, pay such
Loans in accordance with this Credit Agreement.

    2.10  Illegality.  Notwithstanding any other provision in this Credit
          ----------                                                     
Agreement, in the event that it becomes unlawful for Bank to (a) honor its
undertaking to make Eurodollar Loans hereunder, or (b) maintain such Eurodollar
Loans hereunder, then Bank shall promptly notify Borrower thereof and Bank's
undertaking to make such Loans shall be suspended until such time as Bank may
again make and maintain such affected Loans and interest rate option, and
Borrower shall, on the last day(s) of the then current Interest Period(s) for
the outstanding Eurodollar Loans (or on such earlier date as Bank may specify to
Borrower, due to the illegality of maintaining such Loans), pay such Loans in
accordance with this Credit Agreement.

    2.11 Compensation. Borrower shall pay to Bank, upon the request of Bank and
         ------------       
within fifteen (15) days of such request, such amount or amounts as shall be
sufficient (in the reasonable opinion of Bank) to compensate it for any loss,
cost or expense which Bank determines is attributable to:
<PAGE>
 
                                       10


          (a) any payment or prepayment of a Eurodollar Loan, where such payment
     or prepayment occurs on a date other than the last day of an Interest
     Period for the respective Loans (whether by reason of demand by Bank for
     payment or otherwise); or

          (b) any failure by Borrower to, on the date specified therefor in the
     relevant notice under this Credit Agreement, enter into a Eurodollar Loan.

Without limiting the foregoing, such compensation shall include an amount equal
to the excess, if any, of (i) the amount of interest which otherwise would have
accrued on the principal amount so paid or prepaid or not borrowed for the
period from and including the date of such payment or prepayment or failure to
borrow to but excluding the last day of the then current Interest Period for
such Loan (or, in the case of a failure to borrow to but excluding the last day
of the Interest Period for such Loan which would have commenced on the date
specified therefor in the relevant notice) at the applicable rate of interest
for such Loan provided for herein over (ii) the amount of interest (as
reasonably determined by Bank) the Reference Bank would have bid in the London
interbank market (if such Loan is a Eurodollar Loan) for U.S. Dollar deposits
for amounts comparable to such principal amount and maturities comparable to
such Interest Period.  A determination of the Bank as to the amounts payable
pursuant to this Part shall be conclusive absent manifest error.

    2.12  Survival.  The undertaking of Borrower under this Part 2 shall survive
          --------

materially and adversely affect the financial condition or operations of
Borrower or of any Subsidiary or (b) any representation or warranty made in this
Credit Agreement or in any writing related to it may for any reason cease in any
material respect to be true and complete.

     greater than 1.50 to 1.

    (b)  Permit Consolidated Net Worth to be at any time less than the sum of 
     (i) Consolidated Net Worth as of September 30, 1997, (ii) fifty percent
     (50%) of positive Consolidated Net Income for the fiscal quarter then
     ended, plus (iii) one hundred percent (100%) of the increase in
     Consolidated Net Worth for the current fiscal year resulting from the
     issuance of equity securities in such fiscal year.

microchips (including systems and equipment supplied by others or with which
Borrower's systems interface) and the testing of all such systems and equipment,

such reprogramming and testing and of the reasonably foreseeable consequences of
year 2000 to Borrower (including, without limitation, reprogramming errors and
the failure of others' systems or equipment) will not result in an Event of
Default or have a material adverse effect on Borrower.  Except for such of the
reprogramming referred to in the preceding sentence as may be necessary, the
computer and management information systems of Borrower and its Subsidiaries are
and, with ordinary course upgrading and maintenance, will continue to be,
sufficient to permit Borrower to conduct its business without a material adverse
effect.

         (e) Any event occurs or condition exists which, with notice or lapse of

PART 10. MISCELLANEOUS
- -------  -------------

    10.1 Waivers.  No delay or failure of Bank in exercising any right, power or
         -------                                                                
privilege under this Credit Agreement will affect that right, power or
privilege.  No single or partial exercise,  abandonment, or discontinuance of
steps to enforce a right, power or privilege under this Credit Agreement will
preclude Bank from any further exercise of that, or of any other, right, power
or privilege.  The rights and remedies of Bank under this Credit Agreement are
cumulative and, notwithstanding Part 10.7, not exclusive of any rights or
remedies which it would otherwise have. Any waiver, permit, consent or approval
of any kind or character on the part of Bank of any breach or default under this
Credit Agreement or any such waiver of any representation, warranty, provision
or condition of this Credit Agreement must be in a writing executed by Bank and
shall be effective only to the extent specifically set forth in that writing.

    10.2 Banker's Lien/Set-Off.  Nothing in this Credit Agreement shall be
         ---------------------                                            
deemed as a waiver or prohibition of Bank's rights of banker's lien or set-off.

    10.3 Notices.  All notices, statements, requests and demands given to or
         -------                                                            
made upon any party hereto in accordance with the provisions of this Credit
Agreement shall be deemed to have been given or made (a) if mailed, two (2)
Business Days after such writing shall have been deposited in the mail, postage
pre-paid, (b) if telecopied, upon receipt of the transmission provided that the
teletransmission device used shall be capable of creating a written record of
the notice and its receipt, (c) if sent by overnight courier, one (1) Business
Day after such writing shall have been deposited with the overnight courier,
charges prepaid or (d) in the case of telegraphic notice, when delivered to the
telegraph company, charges prepaid, addressed to Bank and to Borrower at their
respective addresses set forth in this Credit Agreement (or to such address or
telecopier number as either party may hereafter furnish to the other party in
writing for such purpose) or in accordance with any unrevoked written direction
from any party to the other party hereto.

    10.4 Costs.  Borrower agrees (a) to pay Bank's reasonable documentation fee
         -----                                                                 
and all out-of-pocket expenses incurred in connection with the preparation,
execution, and delivery of this Credit Agreement, the Note, the Collateral
Documents and all other documentation relating to the Credit Agreement and any
amendments hereto or thereto; (b) to pay all costs and expenses (including
reasonable attorney's fees, both outside counsel and the allocated cost of in-
house counsel), if any, in connection with the enforcement or collection of this
Credit Agreement, the Note and the Collateral Documents arising after the
occurrence of any event which with notice or lapse of time would constitute an
Event of Default, unless such occurrence is cured by Borrower within any
applicable grace period or such reimbursement is not required by the terms of
any waiver granted by Bank in respect of such occurrence, as well as any and all
stamp and other taxes, and (c) to save Bank harmless from any and all
liabilities with respect to or resulting from any delay or omission to pay such
taxes, if any, which may be payable or determined to be payable in connection
with the execution and delivery of this Credit Agreement, the Note or the
Collateral Documents.  The obligations of Borrower under this paragraph shall
survive the payment of the Note.

    10.5 Litigation.  In the event of litigation under this Credit Agreement,
         ----------                                                          
Borrower agrees to submit to the jurisdiction of the courts of appropriate

                                       24

Borrower agrees that Bank may serve process on it by certified mail mailed to
its principal place of business as stated in this Credit Agreement without prior
attempt at personal or substituted service. BORROWER WAIVES ANY RIGHT TO TRIAL
BY JURY OF ANY ISSUE CONNECTED WITH THIS CREDIT AGREEMENT, THE NOTE OR THE
COLLATERAL DOCUMENTS, OR ANY OTHER DOCUMENTATION RELATING THERETO, OR THE
ENFORCEMENT OF ANY OF THOSE DOCUMENTS OR INSTRUMENTS. BORROWER WAIVES THE RIGHT
TO INTERPOSE COUNTERCLAIMS OF ANY NATURE, EXCEPT COMPULSORY COUNTERCLAIMS.

    10.6 New York Law.  This Credit Agreement and the Note issued hereunder
         ------------                                                      
shall be deemed to be contracts under the laws of the State of New York, and for
all purposes shall be governed by and construed in accordance with the laws of
that State, provided, however, that nothing herein shall be deemed a waiver by
Bank of any rights under any federal law establishing rates of interest which
may be charged by a national bank.

    10.7 Compliance with Usury Laws.  Notwithstanding any other provision of
         --------------------------                                         
this Credit Agreement, Borrower shall not be required to pay any amount pursuant
to this Credit Agreement which is in excess of the maximum amount permitted
under applicable law.  It is the intention of the parties hereto to conform
strictly to any applicable usury law, and it is agreed that if any amount
contracted for, chargeable or receivable under this Credit Agreement shall
exceed the maximum amount permitted under any such law, any such excess shall be
deemed a mistake and canceled automatically and, if theretofore paid, shall be
refunded to Borrower.

    10.8 Entire Agreement/Amendment.  This Credit Agreement, and the documents
         --------------------------                                           
executed and delivered pursuant hereto, constitute the entire agreement between
the parties.  None of the terms or provisions hereof or thereof may be altered,
modified, or amended except by an agreement in writing signed by Bank and
Borrower.  If any provision of this Credit Agreement shall be held invalid under
any applicable laws, that provision's invalidity shall not affect any other
provision of this Credit Agreement that can be given effect without the invalid
provision.

         ------------                                                         
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute but one and the same instrument.

    10.10  Successors and Assigns.  This Credit Agreement shall be binding upon
           ----------------------                                              
and inure to the benefit of Bank and Borrower and their respective successors
and assigns, except that Borrower may not assign or transfer its rights
hereunder without Bank's prior written consent.

    Notwithstanding anything to the contrary contained herein, Bank may at any
time assign all or any portion of its rights under this Credit Agreement, the
Note and the Collateral Documents to a Federal Reserve Bank as collateral in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System and the applicable operating circular of such Federal Reserve Bank.

    10.11  Headings.  The headings to Parts appearing in this Credit Agreement
           --------

           --------------                                                
conditions of this Credit Agreement are inconsistent with the terms, provisions

                                 CREDIT NOTE

                                                Billerica, Massachusetts
$20,000,000                                     Date: June 16, 1998

     FOR VALUE RECEIVED, the undersigned ("Borrower") hereby promises to pay to
the order of THE CHASE MANHATTAN BANK ("Bank") at an office at 999 Broad Street,
Bridgeport, Connecticut  06604, on June 16, 2000 the principal sum of Twenty
Million and no/100 Dollars ($20,000,000) or, if less, the last sum shown in the
"Unpaid Principal Balance" Column on the grid attached to this Note, which
represents all Loans made by Bank to Borrower from time to time pursuant to a
Revolving Credit Agreement dated as of June 16, 1998 between Bank and Borrower
("Credit Agreement").

     Interest on this Credit Note shall be calculated on an actual/360 day basis
(i.e., interest for each day is computed by multiplying the principal amount
outstanding by the interest rate and dividing by 360) and including any time
extended by reason of Saturdays, Sundays and holidays.  Accrued interest shall
be payable as set forth in Section 2.4 of the Credit Agreement.

     Bank shall maintain records of the date, amount, interest rate option and
Interest Period for each borrowing under and pursuant to Part 2 of the Credit
Agreement and this Credit Note, as well as the date and amount of each
prepayment of principal hereof.  Prior to any transfer of this Credit Note (or,
at the discretion of Bank, at any other time), Bank may endorse the attached
grid portion of this Note with an appropriate notation reflecting the Credit
Loans, any payments attributable thereto and the initials or other identifying
symbol of the person making the notation.  Borrower agrees that such books and
records of Bank showing the amounts outstanding hereunder shall be prima facie
evidence of the loans made hereunder.  Any failure by Bank to endorse the grid
portion of this Credit Note attached hereto shall not negate the obligation of
Borrower to repay all amounts due and owing hereunder.

     This Credit Note is the Credit Note referred to in, is entitled to the
benefits of, and is subject to the Credit Agreement.  Reference is made to the
Credit Agreement for a statement of its terms and provisions which, among other
things, contain provisions for repayment and the acceleration of the maturity
hereof upon the happening of certain stated events.  All capitalized words and
phrases in this Credit Note have the meanings respectively given to them in the
Credit Agreement except as otherwise defined in this Credit Note.

     This Credit Note is governed by and construed in accordance with the laws
of the State of New York.
