                                    PART I

ITEM 1.  BUSINESS

                                    GENERAL
                                    -------

Integrated Circuit Systems, Inc. (the "Company") was incorporated in
Pennsylvania in 1976, and began by designing and marketing custom application
specific integrated circuits ("ASICs") for various industrial customers.  In
particular, the Company was noted for its unique expertise in designing ASICs
which combined both analog and digital, or "mixed-signal", technology.  By 1988,
the Company had adopted a strategy of developing proprietary integrated circuits
("ICs") to capitalize on its complex mixed-signal design technology and
pioneered the market for frequency timing generators ("FTGs") which provide the
timing signals or "clocks" necessary to synchronize high performance electronic
systems.  FTGs replaced the multiple crystal oscillators and other peripheral
circuitry previously used to generate and synchronize timing signals, thus
providing savings in board space, power consumption and cost.  The Company's FTG
products were initially used in video graphics applications in personal
computers ("PCs"), but subsequently expanded to include motherboards and PC
peripheral devices such as disk drives, audio cards and laser printers.  More
recently, the Company has further extended the use of its mixed-signal expertise
to develop products for data communication applications.  The Company currently
considers its various design, manufacture and marketing activities to be a
single industry segment.

The Company's initial public offering of Common Stock occurred in June 1991, at
which time the Company's Common Stock commenced trading on the Nasdaq National
Market under the symbol ICST.

ACQUISITIONS/DIVESTITURES

While the Company has pursued strategic acquisitions,  in an effort to focus
limited engineering resources on higher return product lines, the Company has
also selectively pruned its product portfolio.

In the second quarter of fiscal 1993, the Company acquired Avasem Corporation
("Avasem"), a privately held company producing FTGs primarily for PC
motherboards, as well as other custom mixed signal IC components.  In the first
quarter of fiscal 1994, the Company acquired Turtle Beach Systems, Inc.,
("Turtle Beach") a privately held company engaged in the design, development and
marketing of sound board and software products primarily for the PC multimedia
market.  These acquisitions were structured as tax-free reorganizations solely
in exchange of common stock of the Company, and were accounted for as pooling of
interests.  Accordingly, all financial information for periods prior to the
acquisition have been restated to reflect the combined operations of these
companies prior to the acquisition.

In the third quarter of fiscal 1995, the Company acquired a 51% interest in ARK
Logic, Inc., ("ARK Logic") a privately held company developing graphic
accelerator chips.  In the second quarter of fiscal 1996, the Company's Turtle
Beach subsidiary acquired the PC multimedia and communications
<PAGE>
 
upgrade product lines of Value Media, Inc.,  ("Value Media") a privately held
company that developed and marketed multimedia peripheral kits for PCs.  In the
third quarter of fiscal 1997, the Company acquired MicroClock, Inc., a leading
producer of clock synthesizer integrated circuits for multimedia applications
including PC, audio, digital set-top boxes, DVD, PC networking disk drives and
modems.  These acquisitions were accounted for using the purchase method, and
are accordingly included in the Company's consolidated financial statements from
the date of the acquisition.

In the first quarter of fiscal 1997, the Company sold Galaxy Power, Inc.,
containing its battery charge controller product line, to Edward H. Arnold,
former chairman and CEO of the Company in a tax-free transaction in which a gain
was recorded. In the second quarter of fiscal 1997, Turtle Beach merged with
Voyetra Technologies, Inc., ("Voyetra") a supplier of music and audio software
and the Company thereby exchanged its approximately 87% interest in Turtle Beach
for an approximately 35% interest in the combined entity. There was no gain or
loss recorded on this transaction. During the fourth quarter of fiscal 1997, the
Company determined that significant events and changes in circumstances had
occurred that indicated an impairment loss on this investment. Subsequently, the
Company disposed of its investment in Voyetra in exchange for extinguishment of
certain potential liabilities with respect to Turtle Beach. In the fourth
quarter of fiscal 1997, the Company sold for cash approximately 80 percent of
its equity position in ARK Logic, Inc., which was previously recorded as
discontinued operations in the third quarter of fiscal 1997, to Vision 2000
Ventures, Ltd., a privately held Cayman Islands investment holding company. The
Company's remaining ownership interest in Ark Logic, approximately 11%, was
written off in the fourth quarter of fiscal 1997.

                       PRODUCTS AND PRODUCT APPLICATIONS
                       ---------------------------------

FREQUENCY TIMING GENERATORS

MOTHERBOARD AND PERIPHERAL APPLICATIONS.  The Company supplies a broad line of
FTG products for use in PC motherboard and peripheral applications, which
provide the numerous frequency outputs required for various timing functions
required by personal computer systems.  These FTGs control multiple functions by
providing and synchronizing the timing of the computer system, including signals
from the video screen, graphics controller, memory, keyboard, microprocessor,
disk drives and communication ports.  The Company has continued to expand its
presence in the non-PC market, and products designed for these applications
contributed over 20% of the Company's FTG revenues in fiscal 1998.

Major OEM customers in fiscal 1998 include:  Acer, Asustek, Intel, Compaq, IBM,
Hewlett-Packard, Siemens,  and Seagate.
<PAGE>
 
DATA COMMUNICATIONS

The Company has also developed and, since late fiscal 1995, marketed transceiver
chipsets for data communications applications, including ATM and SONET. During
the first quarter 1997, the Company introduced a single chip, CMOS, 10/100
megabit per second PHYceiver product for Fast Ethernet applications. A cost
reduced version of this product was engineered during the fiscal year. In fiscal
1998, the Company sold over 3.5 million of these chips to customers such as
Compaq, Hitachi, Hewlett Packard, Lexmark, Racore and Silicon Graphics.

While this product experienced strong demand, the Company was unable to fully
respond to potential backlog due to capacity constraints.  Reflecting this and
increased competition in the market from new participants in single channel
10/100 megabit transceivers as well as new generations of integrated
transceivers, the Company has recently lost market share and experienced severe
price erosion.

SYSTEMS TECHNOLOGY

The Company has developed and sold leading edge mixed-signal ICs customized to
specific needs of a broad range of customers and market applications.  Custom
ICs are typically sold pursuant to development and production contracts which
generally provide for partial reimbursement of development costs and a minimum
production commitment to be purchased by the customer after approval of a
prototype.  Unit prices for custom IC products are negotiated based on factors
which include complexity of the design, minimum purchase requirements and the
Company's production and testing costs.

                              SALES AND MARKETING
                              -------------------

The Company markets its IC component products worldwide through a network of
independent sales representatives and distributors managed by a direct sales
force of employees. During fiscal 1998, the Company conducted its direct sales
efforts through its offices in Norristown, PA, San Jose, CA, Houston, TX, and
Taipei, Taiwan. The Company has over 400 OEM customers, including Compaq, DEC,
Fujitsu Devices, Hewlett Packard, IBM, Intel, SCI, Silicon Graphics, Solectron,
and Sun Microsystems. No customer represented 10% or more of the Company's
revenues in fiscal 1998.

Foreign sales are directly conducted by sales representatives and distributors
located in the Pacific Rim and Europe, and managed by direct sales staff in the
Taiwan sales office and the San Jose facility.  Foreign sales are denominated in
U.S. dollars and are subject to risks common to export activities, including
governmental regulation and trade barriers.

The Company includes in its backlog customer released orders with firm schedules
for shipment within the next twelve months.  These orders may not be canceled
generally without 30 days advance notice. The Company has experienced a
reduction in customer order lead times for its IC products and its "turns"
business (i.e., orders placed by customers for immediate or short term delivery
within the same quarter) has grown to a significant share of its quarterly
revenue.

The Company's revenues are subject to fluctuations primarily as a result of
competitive pressures on selling prices, changes in the mix of products sold,
the timing and success of new product introductions and the scheduling of orders
by customers.

The Company generally warrants that its products will be free from defects in
workmanship and materials for a one-year period.  Defective products returned to
the Company within the warranty
<PAGE>
 
period are replaced or refunded after a confirming evaluation by the Company's
quality control staff. The Company has not experienced significant warranty
returns to date.

                                 MANUFACTURING
                                 -------------

The Company qualifies and utilizes third party suppliers for the manufacture of
silicon wafers. Such suppliers are capable of providing CMOS processing
technologies ranging from 0.35 to 3.0 micron. All of the Company's wafers
currently are manufactured by outside suppliers, three of which supply the
substantial majority of the Company's wafers.  The Company and its suppliers
typically agree on production schedules based on order backlog and demand
forecasts for the next three months.

Although most of the Company's relationships with its wafer suppliers do not
currently provide for the supplier to supply, or the Company to purchase,
substantial minimum wafer quantities, the Company has, on occasion, made
negotiated commitments to purchase specified minimum wafer quantities in
exchange for supply commitments and/or pricing concessions. The Company has an
outstanding wafer supply contract with Chartered Semiconductor Manufacturing PTE
Ltd. ("CSM") pursuant to which the Company had placed a deposit of $10.0 million
in exchange for a commitment by CSM to supply an agreed minimum quarterly
quantity of wafers over a five-year period from April 1996 through December
2000. As of June 27, 1998, approximately $7.9 million remains on deposit with
CSM pursuant to this arrangement.

During the fourth quarter of fiscal 1997, the Company initiated plans to set up
a test and drop-ship facility in Singapore's Kolam Ayer Industrial Park to
achieve faster delivery of its products to customers throughout the Pacific Rim.
The Singapore facility handles wafer probe and final testing for various
integrated circuits used in personal computers, data storage devices and other
peripheral applications. The facility began testing devices in the first quarter
of 1998 and shipments began in the second quarter of fiscal 1998.

The Company believes that adequate capacity will be available to support its
manufacturing requirements.  The Company's reliance, however, on multiple,
offshore, outside subcontractors involves several risks, including capacity
constraints or delays in timely delivery and reduced control over delivery
schedules, quality assurance and costs.  The Company is continuously seeking to
obtain additional sources of supply and capacity for more advanced process
technologies, although there can be no assurance that such additional sources
and capacity can be obtained.  The occurrence of any supply or other problems
resulting from these risks could have a material adverse effect on the Company's
operating results.


                           RESEARCH AND DEVELOPMENT
                           ------------------------

The Company believes that it must continually introduce new products to take
advantage of market opportunities and maintain its competitive position.
Research and development efforts concentrate on the design and development of
new leading edge products for the Company's markets and the continual
enhancement of the Company's design capabilities. Expenditures for research and
development were approximately $19.8 million, $13.5 million and $10.5 million in
fiscal 1998, 1997 and 1996, respectively, and include expenses related to the
development of the Company's recently introduced data communication products as
well its FTG and custom products. Such expenses typically include costs for
engineering personnel, prototype and wafer mask costs, and investment in design
tools and support overheads related to new and existing product development.
<PAGE>
 
The Company expects to continue to increase its spending for research and
development in absolute dollar amounts in the foreseeable future. Because design
of the Company's products is extremely complex, the Company has experienced
delays from time to time in completing products on a timely basis. The design of
the Company's products is an extremely complex iterative process involving the
development of a prototype product through computer-aided circuit design, the
generation of photo masks for the manufacturing process and the fabrication of
wafers. Throughout this process, the Company's engineering staff reviews
preliminary performance data against the original product specifications.
Resulting variances, if any, may require redesign of previously completed
elements and result in the lengthening of the design, and thus the production
cycle.


                       PATENTS, LICENSES AND TRADEMARKS
                       --------------------------------

The Company holds several patents, as well as copyrights, mask works, and
trademarks with respect to its various products and expects to continue to file
applications for the same in the future as a means of protecting its technology
and market position.  In addition, the Company seeks to protect its proprietary
information and know-how through the use of trade secrets, confidentiality
agreements and other security measures.  There can be no assurance, however,
that these measures and/or others will be adequate to safeguard the Company's
interests or preserve the Company's leading edge in certain of its technology
and products or protect it from allegations regarding potential patent
infringement.  To augment product feature sets or accelerate development
schedules, the Company licenses certain technologies.  No single license,
however,  is deemed to be material to the consolidated business of the Company.
In certain instances, the Company has performed design services pursuant to an
agreement by which it transferred certain of its  intellectual property rights
in the final product to its customers.  Such transfers are also not deemed
material to the consolidated business of the Company.

As is typical in the semiconductor industry, the Company from time to time has
been notified that it may be infringing certain patents and other intellectual
property rights of others.  Such matters are evaluated and reviewed with
counsel.  To date, matters of this nature have not resulted in material
litigation against the Company.  There can be no assurance, however, that
litigation will not be commenced in the future regarding any claim of
infringement of any intellectual property right, or that, if required, any
licenses or other rights could be obtained on acceptable terms.


                                  COMPETITION
                                  -----------

In general, the semiconductor and PC component industries are intensely
competitive and characterized by rapid technological changes, price erosion,
cyclical shortages of materials, and variations in manufacturing yields and
efficiencies.  The Company's ability to compete in this dynamic and
opportunistic environment depends on factors both within and outside its
control, including  new product introduction, product quality, product
performance and price, cost-effective manufacturing, general economic
conditions, the performance of competition and the growth and evolution of the
industry in general.  In the latter regard there are several substantial
entities, the Company not being one of them, in the industry who could, and do,
exert significant influence in determining the pace and key trends in the
development of PCs and PC components.  Moreover, some of the Company's current
and potential competitors have significantly greater financial, technical,
manufacturing and marketing resources than the Company.  Competitors also
include privately owned and emerging companies attempting to secure a share of
the market for the Company's products.

                          FORWARD-LOOKING STATEMENTS
                          --------------------------

   The statements contained or incorporated by reference in this Annual Report
on Form 10-K or the Exhibits hereto that are not historical facts or statements
of current condition are forward-looking statements.  Such forward-looking
statements may be identified by, among other things, the use of forward-looking
terminology such as "believes," "expects," "forecasts," "estimates," "plans,"
"continues," "may," "will," "should,"  "anticipates" or "intends," or the
negative thereof or other variations thereon or comparable terminology, or by
discussions of strategy or intentions.  These forward-looking statements, such
as statements regarding Year 2000, anticipated future new product introductions,
revenues, capital expenditures, acquisitions, management and production
activities, and other statements regarding matters that are not historical
facts, involve predictions.  The Company's actual results, performance or
achievements could differ materially from the results expressed in, or implied
by, these forward-looking statements.  Potential risks and uncertainties that
could affect the Company's results, performance or achievements include, but are

cautioned not to place undue reliance on any such forward looking statements.
Furthermore, the Company disclaims any obligation or intent to update any such
factors or forward-looking statements to reflect future events or developments.

RISK FACTORS
In addition to the other information in this Annual Report on Form 10-K, the
following risk factors should be carefully considered.

DEPENDENCE ON CONTINUOUS INTRODUCTION OF NEW PRODUCTS BASED ON THE LATEST
TECHNOLOGY

   The markets for the Company's products are characterized by rapidly changing
technology, evolving industry standards and frequent new product introductions.
Product life cycles are continually becoming shorter,  which causes the gross
margins of semiconductor products to decline precipitously as the next
generation of competitive products (which are often  more technologically
sophisticated) are introduced.  Because of this almost inevitable product
obsolescence and declining margins, the Company's future success is highly
dependent upon its ability to continually develop new products using the latest
and most cost-effective technologies, introduce them in commercial quantities to
the marketplace ahead of the competition and have them selected for inclusion in
products of leading systems manufacturers.  There can be no assurance that the
Company will be able to regularly develop and introduce such new products on a
timely basis or that products developed by the Company, including recently
introduced products, will be selected by systems manufacturers for incorporation
into their products.  The Company's failure to develop such new products, or to
have its products available in commercial quantities ahead of competitive
products and selected for inclusion in products of systems manufacturers, would
have a material adverse effect on the Company's results of operations and
financial condition.

INTENSELY COMPETITIVE INDUSTRY
 
   The semiconductor and PC component industries are intensely competitive. The
Company's ability to compete depends highly on elements outside the Company's
control, such as general economic conditions affecting the semiconductor and PC
industries and the introduction of new products and technologies by competitors.
Most of the Company's competitors and potential competitors have significantly
greater financial, technical, manufacturing and marketing resources than the
Company. These competitors include major multinational corporations possessing
worldwide wafer
<PAGE>
 
fabrication and integrated circuit production facilities and diverse,
established product lines. Competitors also include emerging companies
attempting to obtain a share of the existing market for the Company's current
and proposed products. To the extent that the Company's products achieve market
acceptance, competitors typically seek to offer competitive products or embark
on pricing strategies which, if successful, could have a material adverse effect
on the Company's results of operation and financial condition.

   The Company has directed significant resources towards the objective of
establishing growth in networking transceiver markets.  In order to succeed, the
Company may have to displace larger and more established competitors in these
markets.  There can be no assurance that the Company will be successful in its
efforts or that even if market penetration were to be achieved the networking
transceiver products would be profitable or that competitive responses would not
have a material adverse impact on future profitability.

DEPENDENCE ON FREQUENCY TIMING PRODUCTS

   The Company's frequency timing generator products for use in motherboard and
peripheral applications for PCs accounted for approximately 51.4%, 53.7% and
45.6% of the Company's total revenue in fiscal years 1998, 1997 and 1996,
respectively.  The Company believes that competitors increasingly are becoming
second source suppliers of products which could be substituted for certain of
the Company's PC video graphics products.  Some suppliers of other complementary
IC video products, such as video graphics controllers, have begun to integrate
the video timing generator function into other products, primarily for lower
performance applications.  As a result, the Company has experienced, and may
continue to experience, downward pricing pressure on and competition in certain
of its PC video graphics frequency timing generator products.  Future sales may
be materially and adversely affected by the availability and sales of these
competing products.  Additionally, there can be no assurance that the Company
will be able to increase revenues in the future relating to its frequency timing
generator products.

DEPENDENCE ON PC INDUSTRY

   A substantial portion of the sales of the Company's products depend largely
on sales of PCs and peripherals for PCs. The PC industry is subject to extreme
price competition, rapid technological change, evolving standards, short product
life cycles and continuous erosion of average selling prices. Should the PC
market decline or experience slower growth, then a decline in the order rate for
the Company's products could occur during a period of inventory correction by PC
and peripheral device manufacturers, which could result in a decline in revenue
or a slower rate of revenue growth for the Company. A downturn in the PC market
could also affect the financial health of some of the Company's customers, which
could affect the Company's ability to collect outstanding accounts receivable
from such customers. Furthermore, the intense price competition in the PC
industry is expected to continue to put pressure on the price of all PC
components, including the Company's products, thus reducing profit margins.

   The PC industry also depends upon sales worldwide, and recent economic
turmoil in the Pacific Rim will substantially reduce sales of PCs in that
geographic area.  The ultimate impact on the Company cannot be determined at
this time.  Similar regional economic crisis, whether in developing or mature
markets, could also impact sales of PCs and peripherals for PCs, and thus impact
sales of the Company's products.
<PAGE>
 
DEPENDENCE ON OUTSIDE WAFER FOUNDRIES AND ASSEMBLERS

   The Company currently depends entirely upon third party suppliers for the
manufacture of the silicon wafers from which its finished circuits are
manufactured, and for the assembly of finished integrated circuits from silicon
wafers.

   There can be no assurance that the Company will be able to obtain adequate
quantities of processed silicon wafers within a reasonable period of time or at
commercially reasonable rates , and the semiconductor industry has experienced
disruptions from time to time in the supply of processed silicon wafers due to
quality or yield problems or capacity limitations.  Virtually all of the
Company's wafers are manufactured by three outside foundries.  If one or more of
these foundries are unable or unwilling to produce adequate supplies of
processed wafers on a timely basis, it could cause significant delays and
expense in locating a new foundry and redesigning circuits to be compatible with
the new manufacturer's process and, consequently, could have a material adverse
effect on the Company's results of operation and financial condition.
 
   The Company also relies entirely upon third parties for the assembly of
finished integrated circuits from processed silicon wafers.  The Company
currently relies on four assemblers, two of which produce most of the Company's
finished integrated circuits.  While the Company believes that there is
typically a greater availability of assemblers than silicon wafer foundries, it
could none the less incur significant delays and expense if one or more of the
assemblers upon which the Company currently relies become unable or unwilling to
assemble finished integrated circuits from silicon wafers.

   Two of the foundries that manufacture the silicon wafers from which finished
circuits are manufactured, and all of the third parties used by the Company to
assemble finished integrated circuits, are located in the Pacific Rim.  The
Company has typically relied upon production and assembly in this geographic
area because of the abundance of third parties performing these services, as
well as the geographic proximity to manufacturers of PCs and other equipment in
that region that use the Company's products.  The impact of the current
financial crisis in the Pacific Rim countries on the Company's operations in
this area cannot yet be determined.  It is possible, among other things, that
one or more of the Company's key suppliers could face insolvency or other
financial risks due to the economic crisis in that region which would require
them to cease operations.  This could cause a delay in the Company's production
and delivery of commercial quantities of its products, which in turn could
materially adversely affect the Company's revenues and financial condition.  See
"Risks Associated with International Business Activities."

RISKS ASSOCIATED WITH INTERNATIONAL BUSINESS ACTIVITIES

   For the fiscal years 1998, 1997 and 1996, the Company generated approximately
58.8%, 60.3% and 46.8% of its net sales, respectively, from international
markets.  These sales were generated primarily from the Company's customers in
the Pacific Rim region and included sales to foreign corporations, as well as to
foreign subsidiaries of U.S. corporations.  The Company estimates that in fiscal
1998, approximately one-half of the Company's sales in international markets
were to foreign corporations, with the bulk of them being in Taiwan.

   In addition, two of the Company's wafer suppliers and all of the Company's
assemblers are located in the Pacific Rim.  Several countries in this region
have experienced currency devaluation and/or difficulties in financing short-
term obligations.  There can be no assurance that the effect of this economic
crisis on the Company's wafer suppliers will not impact the Company's wafer
supply or assembly operations, or that the effect on the Company's customers in
that region will not adversely
<PAGE>
 
affect both the demand for the Company's products and the collectibility of
receivables. See "Dependence on Outside Wafer Foundries and Assemblers."

   The Company's international business activities in general are subject to a
variety of potential risks resulting from certain political, economic and other
uncertainties including, without limitation, political risks relating to a
substantial number of the Company's customers being in Taiwan.  Certain aspects
of the Company's operations are subject to governmental regulations in the
countries in which the Company does business, including those relating to
currency conversion and repatriation, taxation of its earnings and earnings of
its personnel, and its use of local employees and suppliers.  The Company's
operations are also subject to the risk of changes in laws and policies in the
various jurisdictions in which the Company does business which may impose
restrictions on the Company.  The Company cannot determine to what extent future
operations and earnings of the Company may be effected by new laws, new
regulations, changes in or new interpretations of existing laws or regulations
or other consequences of doing business outside the U.S.

   The Company's activities outside the U.S. are subject to additional risks
associated with fluctuating currency values and exchange rates, hard currency
shortages and controls on currency exchange.  Additionally, worldwide
semiconductor pricing is influenced by currency fluctuations, and the recent
devaluation of the currencies of several countries in the Pacific Rim could have
a significant impact on the prices of the Company's products if its competitors
offer products at significantly lower prices in an effort to maximize cash flows
to finance short-term, dollar denominated obligations; such devaluations could
also impact the competitive position of the Company's customers in Taiwan and
elsewhere, which could impact the Company's sales.

RISKS ASSOCIATED WITH ACQUISITIONS; INTEGRATION OF OPERATIONS

   An element of the Company's growth strategy has been to pursue strategic
acquisitions that expand and complement the Company's business.  Acquisitions
involve a number of risks inherent in assessing the values, strengths,
weaknesses and profitability of acquisition candidates including: adverse short-
term effects on the Company's operating results; diversion of management's
attention; dependence on retaining key personnel; amortization of acquired
intangible assets; and risks associated with unanticipated problems and latent
liabilities or contingencies.  In addition, the Company's acquisitions of other
companies and product lines will require the integration of their operations
into those of the Company.  There can be no assurance that the Company will be
able to identify appropriate acquisition candidates, or  successfully integrate
acquired operations to realize cost-savings or other synergies, and the failure
to do so could have a material adverse effect on the Company's results of
operations and financial condition.

VARIABILITY OF QUARTERLY RESULTS

   The Company's quarterly and annual operating results have been subject to
substantial fluctuation in the past, and are likely to similarly fluctuate in
the future as a result of a wide variety of factors, including competitive
pressures on selling prices, timing and cancellation of customer orders,
fluctuations in production yields, changes in the mix of products sold,
availability of wafer supply, possible disruptions of operations caused new
foundries or other vendors, political and economic instability in foreign
markets affecting both ultimate customers of the Company's products and the
availability of third-party suppliers for the manufacture, assembly and testing
of silicon wafers and finished circuits, seasonal patterns of spending and
manufacturing  inefficiencies associated with the development and start up of
new products.
<PAGE>
 
   The Company believes that its future quarterly operating results may also
fluctuate as a result of Company-specific factors, including pricing pressures
on its more mature FTG components, fluctuating demand for its custom ASIC
products, acceptance of the Company's newly introduced products and market
acceptance of its customers' products.  In addition, the Company is subject to
fluctuations in the annual business cycles of its original equipment
manufacturer "OEMs" customers.

DEPENDENCE ON PATENTS, TRADE SECRETS AND PROPRIETARY TECHNOLOGY

   The Company holds several patents as well as copyrights, mask works and
trademarks with respect to its various products and expects to continue to file
applications for the same in the future as a means of protecting its technology
and market position.  In addition, the Company seeks to protect its proprietary
information and know-how through the use of trade secrets, confidentiality
agreements and other security measures.  With respect to patents, there can be
no assurance that any applications for patent protection will be granted, or, if
granted, will offer meaningful protection.  Additionally, there can be no
assurance that competitors will not develop, patent or gain access to similar
know-how and technology, or reverse engineer the Company's products, or that any
confidentiality agreements upon which the Company relies to protect its trade
secrets and other proprietary information will be adequate to protect the
Company's proprietary technology.  The occurrence of any such events could have
a material adverse effect on the Company's results of operations and financial
condition.

   Patents covering a variety of semiconductor designs and processes are held by
various companies.  The Company has from time to time received, and may in the
future receive, communications from third parties claiming that the Company may
be infringing certain of such parties' patents and other intellectual property
rights.  Any infringement claim or other litigation against or by the Company
could have a material adverse effect on the Company's results of operations and
financial condition.

DEPENDENCE UPON KEY PERSONNEL

   The Company is dependent upon its ability to attract and retain highly-
skilled technical, managerial and marketing personnel.  The Company believes
that its future success in developing marketable products and achieving a
competitive position will depend in large part upon whether it can attract and
retain skilled personnel. Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining the personnel it requires to successfully develop new and enhanced
products and to continue to grow and operate profitably.  Furthermore, retention
of scientific and engineering personnel in the Company's industry typically
requires the Company to present attractive equity incentive packages, which
could lead to additional dilution.

   Virtually all of the Company's key engineers worked at other companies or at
universities and research institutions before joining the Company.  Disputes may
arise as to whether technology developed by such engineers while employed by or
associated with the Company was first discovered when they were employed by or
associated with others in a manner that would give third parties rights to such
technology superior to the rights, if any, of the Company.  Disputes of this
nature have occurred in the past, and are expected to continue to arise in the
future, and there can be no assurance that the Company will prevail in any such
disputes.  To the extent that consultants, vendors or other third parties apply
technological information independently developed by them or by others to the
Company's proposed products, disputes may also arise as to the proprietary
rights to such information, which may not be resolved in favor of the Company.
 
<PAGE>
 
PRODUCT LIABILITY EXPOSURE AND POTENTIAL UNAVAILABILITY OF INSURANCE

Certain of the Company's custom IC products are sold into the medical markets
for applications which include a blood glucose measurement instrument and
hearing aids.  In certain cases, the Company has provided or received
indemnities with respect to possible third party claims arising from these
products.  Although the Company believes that exposure to third party claims has
been minimized, there can be no assurance that the Company will not be subject
to third party claims in these or other applications or that any indemnification
or insurance available to the Company will be adequate to protect it from
liability.  A product liability claim, product recall or other claim, as well as
any claims for uninsured liabilities or in excess of insured liabilities, could
have a material adverse effect on the Company's results of operations and
financial condition.

VOLATILITY OF THE COMPANY'S STOCK PRICE

Since the initial public offering of the Company's Common Stock in 1991, the
market value of the Company's Common Stock has been subject to significant
fluctuation.  The market price of the Company's Common Stock is likely to
continue to be subject to significant fluctuations in response to operating
results and other factors.  In addition, the stock market in recent years has
experienced price and volume fluctuations that often have been unrelated or
disproportionate to the operating performance of the companies.  These
fluctuations, as well as general economic and market conditions, may adversely
affect the market price of the Company's Common Stock.

</TABLE>

REVENUE

The Company achieved revenue of $160.6 million in fiscal year 1998, as compared
to $104.4 million and $91.3 million in fiscal years 1997 and 1996, respectively.
This increase in fiscal 1998 revenue was attributable to demand increases across
all product lines.


FREQUENCY TIMING GENERATORS

The Company's FTG component revenue increased $26.5 million to $82.6 million for
fiscal 1998 as compared to prior year.  The acquisition of MicroClock, Inc. in
the third quarter of fiscal 1997 accounted for $14.1 million of the increase
with the remaining amount attributable to strong demand from PC motherboard OEM
customers.  The average selling price for FTGs remained the same year to year
from fiscal 1997 to fiscal 1998 while volume increased 45.0%.

FTG components for motherboard and peripheral applications for PCs contributed
approximately 51.4%, 53.7% and 45.6% of total revenue in fiscal years 1998, 1997
and 1996, respectively.  Although the market for FTG motherboard and PC
peripheral applications is expected to  continue to be a major source of
revenue, the Company intends to increase its presence in applications for
communications and consumer electronics, which comprised less than 10% of total
FTG revenue in fiscal 1998.

DATA COMMUNICATIONS

Data Communications' component revenue represented approximately 25.2% of total
revenue in fiscal year 1998, as compared to 15.4% in fiscal 1997 and very little
corresponding revenue in fiscal 1996, reflecting the introduction of the new
1890 transceiver at the end of fiscal 1996.  The Company has experienced
increased competition in the market for single channel 10/100mb LAN
transceivers, which has led to the cancellations of orders and severe price
erosion for this product line.

SYSTEMS TECHNOLOGY

Revenue from Systems Technology comprised 23.4%, 24.4% and 30.8% of total
revenue in fiscal years 1998, 1997 and 1996, respectively, and includes
engineering and design revenue.  The declining trend in Systems  Technology's
products, as a percentage of revenue, reflects overall increases in revenue from
FTG and Data Communication components.

TURTLE BEACH

As a result of the merger of Turtle Beach and Voyetra, Turtle Beach was de-
consolidated commencing November 30, 1996.  The Company's 35% share of net
losses at Voyetra was recorded under the equity method of accounting during the
remainder of fiscal 1997.  Revenues were 6.5% and 23.3% of total revenue in
fiscal 1997 and 1996 respectively.

During the fourth quarter of fiscal 1997, the Company determined that
significant events and changes in circumstances had occurred that indicated it
was probable that its investment in Voyetra would not be recoverable.
Accordingly, the Company recorded an impairment loss of approximately $7.1
million on its investment in Voyetra in the fourth quarter of 1997.
<PAGE>
 
FOREIGN REVENUE

Foreign revenue, which resulted primarily from sales to offshore customers was
58.8%, 60.3% and 46.8% of total revenue in fiscal years 1998, 1997 and 1996,
respectively.  The decrease in fiscal 1998 reflects a substantial increase of
Data Communications shipments in North America. The Company's sales are largely
denominated in U.S. dollars.

COST OF SALES

Cost of sales consists of costs related to the purchase of processed wafers,
assembly and testing services provided by third-party suppliers, as well as
costs arising from in-house product testing, shipping, quality control and
manufacturing support operations.  Cost of sales as a percentage of total
revenue was 55.3% in fiscal 1998, as compared to 56.7% in fiscal 1997 and 60.1%
in fiscal 1996.  The decrease in the cost of sales in fiscal year 1998 reflects
reduced material costs and a favorable product mix.

RESEARCH & DEVELOPMENT

Research and development expense expressed as a percentage of revenue was 12.3%
in fiscal 1998, as compared to 13.0% in fiscal year 1997, and 11.5% in fiscal
1996.  In dollar terms, research and development spending increased 46.4%  from
fiscal year  1997 to  1998,  primarily as a result of hiring  additional
engineering personnel, investment in new design tools and increased activity
related to new product development and enhancement programs for existing
standard products.

SELLING, GENERAL AND ADMINISTRATION

Selling, general and administration expense represents 12.1%, 14.5% and 20.2% of
total revenues in fiscal years 1998, 1997 and 1996 respectively.  In monetary
terms, expenses have increased 28.6% from fiscal 1997 to fiscal 1998, but
decreased 18.2% from fiscal 1996 to fiscal 1997.  The increase from 1997 to 1998
primarily represents increases in variable costs associated with the revenue
growth.  The decrease from fiscal 1996 to fiscal 1997 represents the
deconsolidation of Turtle Beach.

OPERATING INCOME

Expressed as a percentage of revenue, operating income was 20.1%, 4.7% and 4.4%
in fiscal years 1998, 1997 and 1996, respectively.  In dollar terms, operating
income was $32.3 million in fiscal year 1998 compared to $4.9 million and $4.0
million in fiscal years 1997 and 1996, respectively.  Fiscal 1997 includes a
special charge of $11.2 million as a result of the write-off of in-process
research and development costs arising from the acquisition of MicroClock.
Fiscal 1996 includes special  charges of $3.3 million primarily as the result of
Turtle Beach's acquisition of certain assets of Value Media, which included a
$1.5 million write-off of in-process research and development, and the transfer
of Turtle Beach's York, PA operations to Fremont, CA, which resulted in a $1.8
million charge for facility closing. Accordingly, operating income before
special charges was 20.1% of revenue in fiscal year 1998, as compared to 15.4%
and 8.0% in fiscal 1997 and 1996, respectively.

EQUITY  INVESTMENT AND MINORITY INTEREST

On November 29, 1996, the Company signed a Merger Agreement to merge Turtle
Beach Systems with Voyetra in exchange for an approximately 35% equity interest
in the combined business.  In connection with the merger, the Company also
entered into a Revolving Credit Agreement and Note ("Revolving Credit
Agreement") with Voyetra, pursuant to which the Company agreed to make loans to
Voyetra up to an aggregate of $3.5 million, subject to certain covenants. The
Company accounted for its investment in Voyetra under the equity method of
accounting, and recorded an impairment loss on this investment in the fourth
quarter of fiscal 1997.  The minority interest represents the ownership interest
in Turtle Beach Systems that the Company did not own prior to the merger.

During the fourth quarter of fiscal 1997 the Company determined that significant
events and changes in circumstances had occurred subsequent to the merger that
indicated it was probable that its investment in Voyetra would not be
recoverable.  In the opinion of the Company's management, Voyetra experienced an
adverse shift in the fundamentals of its business which resulted in
deteriorating gross profit margins and a substantial increase in operating
losses.  In addition, during the fourth quarter of fiscal 1997, the Company
notified Voyetra that they had violated certain covenants and were in default
under the Revolving Credit Agreement.  As such, the Company was under no
obligation to provide financing under the Revolving Credit Agreement.   As a
result of these significant events in the fourth quarter of fiscal 1997,
management of the Company estimated that the undiscounted cash flows anticipated
for Voyetra would not be sufficient to recover the carrying value of the
Company's investment and a write-down to fair value was required.
Consequently, in the fourth quarter of fiscal 1997, the Company recorded an
impairment loss of $7.1 million on its investment in Voyetra which is included
in the Statement of Operations as Impairment in equity investment.

In the second quarter of fiscal 1998, Voyetra filed a complaint in the Supreme
Court of the State of New York against the Company.  At the end of the second
quarter, the Company and Voyetra reached a settlement.  Voyetra would release
the Company from all claims and all obligations with respect to the
Voyetra/Turtle Beach merger agreement in exchange for assumption of certain
liabilities of Turtle Beach by the Company, a $200,000 cash payment and return
of Voyetra stock held by the Company.  As of June 27, 1998, the Company has
settled these obligations and returned the Voyetra stock.

INCOME TAXES

After adjusting for minority interest and equity investment, the Company's
effective tax rate related to income from continuing operations was 37.5%, 95.8%
and 27.8% for fiscal years 1998, 1997, and 1996, respectively.  The effective
tax rate for fiscal 1998 reflected tax exempt status of  the Company's Singapore
operation, which has been given pioneer status, or exemption of taxes on non-
passive income for five years.  The increased effective tax rate for fiscal 1997
includes a $11.2 million non-deductible intangible write-off related to the
acquisition of MicroClock, Inc. and a $7.1 million capital loss for the
impairment of the Voyetra investment.
<PAGE>
 
NET INCOME (LOSS)

Fiscal 1998 reflects a net income of $21.4 million, or $1.63 per diluted share,
as compared to a net loss of $8.4 million, or ($0.73) per diluted share, for
fiscal 1997, and income of $3.9 million, or $0.34 per diluted share, for fiscal
1996.  Excluding special charges, equity investment related charges and minority
interest, however, net income for fiscal year 1997 was $10.6 million or $0.92
per diluted share and $6.0 million or $0.52 per diluted share for fiscal year
1996.

DISCONTINUED OPERATIONS

During the third quarter of fiscal 1997, the Company implemented a plan, with
approval of the Board of Directors, to dispose of its majority interest in
their subsidiary, ARK Logic, within a 12-month period.  Unlike the Company's
core business of developing mixed signal components, ARK Logic uses different
design tools and technology to engineer complex digital circuits.  Accordingly,
the Company has presented ARK Logic as discontinued operations and all prior
periods have been restated to reflect this presentation.  The Company recorded a
charge of $1.5 million in the third quarter of fiscal 1997, including severance
and other exit costs.  Subsequently, on June 17, 1997, the Company sold
approximately 80% of its holdings in ARK Logic to Vision 2000 Ventures, Ltd for
which a gain of $2.4 million, including the reversal of severance and facility
termination accruals, was recorded.  The Company's remaining ownership interest
in ARK Logic (approximately 11%) was written off in the fourth quarter of fiscal
1997.

LIQUIDITY, CAPITAL RESOURCES AND INFLATION

As of June 27, 1998, the Company's principal sources of liquidity included
approximately $41.8 million in cash and investments, as compared to $26.4
million at June 28, 1997.  The investments primarily consist of commercial
paper, government bonds and marketable securities with various maturities up to
about one year.  During fiscal year 1998, the Company generated $23.4 million in
cash from its operating activities, as compared to $10.4 million during fiscal
year 1997.  The increase in fiscal year 1998 was primarily due to improved
operating results, decreased accounts receivable as a result of improved
collection efforts and reduced inventory. The increase in cash flow was offset
by increased tax payments. The Company's days sales outstanding were reduced
from 51 days in fiscal 1997 to 46 days in fiscal 1998, while inventory turns
increased from 4.2 times in fiscal 1997 to 6.7 times in fiscal year 1998.

Expenditures for property and equipment were $8.1 million in 1998 as compared to
$3.4 million in fiscal year 1997.  The increased expenditures are primarily
attributable to the start up of the Singapore facility and the investment in
design and testing tools and software.
 
During fiscal 1998, under its existing wafer supply contract with Chartered
Semiconductor Manufacturing PTE, Ltd. ("CSM"), the Company advanced the final
$2.0 million installment of its deposit with CSM whereby CSM would supply an
agreed minimum quantity of wafers over a five-year period from April 1996
through December 2000.  The contract requires CSM to refund the Company's
deposit by progressive installments based upon the volume of purchases made by
the Company.  CSM has refunded $2.1 million to the Company in fiscal 1998.  As
of June 27, 1998 and June 28, 1997, amounts due from CSM were $7.9 million and
$8.0 million, respectively.  The Company had previously entered into a similar
agreement with one of its other wafer suppliers, American Microsystems, Inc., by
which deposits totaling $5.5 million were placed in fiscal 1995 and the Company
received $2.6 million from AMI in fiscal 1998 extinguishing the balance of any
outstanding deposit at AMI.

On November 29, 1996, the Company signed a Merger Agreement to sell its
approximately 87% interest in Turtle Beach to Voyetra in exchange for an
approximately 35% equity interest in Voyetra. Voyetra is a supplier of music and
audio software.  In connection with the merger, the Company also entered into a
Revolving Credit Agreement with Voyetra, pursuant to which the Company agreed to
make loans to Voyetra up to an aggregate of $3.5 million, subject to certain
restrictions and covenants.  As of June 28, 1997, Voyetra was not in compliance
with certain covenants.  As such, the Company decided to cease funding under the
Revolving Credit Agreement.

On November 5, 1997, Voyetra filed a complaint in the Supreme Court of the State
of New York against the Company.  On December 31, 1997, the Company and Voyetra
reached a settlement in which Voyetra agreed to release the Company from all
claims and relieve the Company of all obligations with respect to the
Voyetra/Turtle Beach merger agreement in exchange for assumption of certain
liabilities of Turtle Beach, a $200,000 cash payment and the return of Voyetra
stock held by the Company.  As of June 27, 1998, the Company has settled these
obligations and returned the Voyetra stock held by the Company to Voyetra.

On June 17, 1997, the Company sold approximately 80% of its share holdings in
ARK Logic to Vision 2000 Ventures, Ltd. for cash of approximately $2.4 million,
of which 20% is held in escrow.  As part of such divestiture, a shareholders'
agreement, which required the Company to buy the remaining 49% minority interest
in ARK Logic at a future period, was terminated.

During fiscal 1998, the Company repurchased $13.0 million of its common stock
versus $10.5 million in the prior year.  Proceeds and the tax benefit for stock
option exercises were $11.2 million in fiscal 1998 versus $12.8 million in the
prior year.

During fiscal 1998, the Company renegotiated its $20 million revolving/term loan
credit facility with its commercial bank to extend the expiration date to
December 31, 1999.  The facility is subject to certain covenants, including the
maintenance of certain financial ratios and minimum tangible net worth
requirements, as well as a prohibition against the payment of cash dividends
without prior bank approval.  The Company was in compliance with all covenants
as of June 27, 1998.  On June 27, 1998, there was no balance outstanding under
this facility.

In January 1998, the Board of Directors authorized a new stock repurchase
program, which provided for the purchase from time to time of 1.5 million shares
of the Company's common stock.  The timing and amount of shares repurchased will
be determined at the discretion of the Company's management.  As of June 27,
1998, the Company holds approximately 0.8 million shares in treasury stock
valued at $16.7 million, using the cost method.

The Company believes that the existing sources of liquidity and funds expected
to be generated from operations will adequately fund the Company's anticipated
working capital and other operating needs through the next fiscal year.  The
Company has acquired technology companies in the past, and may continue to make
strategic acquisitions in the future.  Such potential transactions may require
substantial resources which, to the extent not provided by internally generated
sources, would require the Company to seek access to debt or equity markets.

For the fiscal years 1998, 1997 and 1996, the Company generated approximately
58.8%, 60.3%, and 46.8% of its net sales, respectively, from international
markets.  These sales were generated primarily from the Company's customers in
the Pacific Rim region and included sales to foreign corporations, as well as to
foreign subsidiaries of U.S. corporations.  The Company estimates that in fiscal
1998, over one-half of the Company's sales in international markets were to
foreign corporations, with the bulk of them being in Taiwan.

In addition, two of the Company's wafer suppliers and all of the Company's
assemblers are located in the Pacific Rim.  Several countries in this region
have experienced currency devaluation and/or difficulties in financing short-
term obligations.  There can be no assurance that the effect of this economic
crisis on the Company's wafer suppliers will not impact the Company's wafer
supply or assembly operations, or that the effect on the Company's customers in
that region will not adversely affect both the demand for the Company's products
and the collectivity of receivables.

The Company's international business activities, in general, are subject to a
variety of potential risks resulting from certain political, economic and other
uncertainties including, without limitation, political risks relating to a
substantial number of the Company's customers being in Taiwan.  Certain aspects
of the Company's operations are subject to governmental regulations in countries
which the Company does business, including those relating to currency conversion
and repatriation, taxation of its earnings and the earnings of its personnel,
and its use of local employees and suppliers.  The Company's operations are also
subject to the risk of changes in laws and policies in the various jurisdictions
in which the Company does business which may impose restrictions on the Company.
The Company cannot determine to what extent future operations and earnings of
the Company may be effected by new laws, new regulations, changes in or new
interpretations of existing laws or regulations or other consequences of doing
business outside the U.S.

The Company's activities outside the U.S. are subject to additional risks
associated with fluctuating currency values and exchange rates, hard currency
shortages and controls on currency exchange. Additionally, worldwide
semiconductor pricing is influenced by currency fluctuations and the recent
devaluation of the currencies of several countries in the Pacific Rim could have
a significant impact on the prices of the Company's products if its competitors
offer products at significantly lower prices in an effort to maximize cash flows
to finance short-term, dollar denominated obligations; such devaluations could
also impact the competitive position of the Company's customers in Taiwan and
elsewhere, which could impact the Company's sales.

INFLATION

Inflation has not had a significant impact on the Company.

YEAR 2000

The Year 2000 issue is the result of computer programs being written using two
digits rather than four digits to define the applicable year.  Computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000.  This could result in a system failure or
miscalculations causing disruptions of operations, a temporarily inability to
process transactions, send invoices, or engage in normal business activities.
<PAGE>
 
Currently, the Company has a formal program in place and well underway that
includes analysis of potentially affected business and process systems and
replacement or correction of all non-compliant critical business and process
systems that it will need in the new millennium.  In concert with this effort,
all suppliers that are critical to the function of the Company are being
surveyed to insure readiness and non-disruption to the Company supply chain.
The Company intends to have their internal application systems, infrastructure
and procedures, and manufacturing and control processes Year 2000 compliant by
mid-1999.

The Company will be required to modify or replace certain portions of its
internal systems.  The Company is using internal resources to reprogram or
replace and test the software for Year 2000 changes.  If these changes or
conversions to new systems are not made in time, the Year 2000 Issue could have
a material impact on the operations of the Company.

The Company relies on subcontractors for wafer manufacture, assembly and testing
of products.  The Company has sent questionnaires to these critical suppliers to
determine the extent to which the Company's operations are exposed to failure of
Year 2000 issues.  The Company is waiting on responses from these suppliers.
There can be no assurance that the Company will be successful in its efforts to
resolve any Year 2000 issues and continue receiving products from these
suppliers.  The failure of resolving these issues could result in a shut-down of
some or all the Company's operations, which would have a material adverse effect
on the Company.

The Company utilizes third-party network equipment and software products, which
may or may not be Year 2000 compliant.  The Company has begun formal
communications, through questionnaires, with critical suppliers of products and
services to determine that the suppliers' operations and the products and
services they provide are Year 2000 capable. The Company is currently awaiting
responses to these questionnaires.  The Company does not currently have any
information concerning the Year 2000 compliance status of its customers.  If any
of the Company's significant customers and suppliers do not successfully and in
a timely manner achieve Year 2000 compliance, the Company's business or
operations could be adversely affected. There can be no assurance that another
company's failure to ensure Year 2000 capability would not have an adverse
effect on the Company.  The products that the Company sells are not date-
sensitive, and therefore product related exposures are low.

The total expense of the Year 2000 project is currently estimated at
approximately $100,000, which is not material to the Company's business
operations or financial condition.  If required modifications to existing
software and conversions to new software are not made, or are not completed in a
timely manner, the Year 2000 could have a material impact on the operations of
the Company. While delays in the implementation of the Year 2000 solutions, or
failure of any critical technology components to operate properly in the Year
2000, could affect the Company's operations, the Company believes that
resolution of the Year 2000 issue will not require material additional costs and
will not have a material adverse effect on the Company's results of operations.
There can be no assurance that these costs will not be material to the Company
or that the Company will be able to resolve these issues in a timely manner.
The expenses of the Year 2000 project are being funded through operating cash
flows.

The Company has not yet fully developed a comprehensive contingency plan to
address situations that may result if the Company is unable to achieve Year 2000
readiness of its critical operations.  There can be no assurance that the
Company will be able to develop a contingency plan that will adequately address
issues that may arise in the year 2000.  The failure of the Company to
successfully resolve such issues could result in shut-down of some or all of the
Company's operations, which would have a material adverse effect on the Company.
<PAGE>
 
The costs of the plan and the date on which the Company believes it will
complete the Year 2000 modification are based on management's best estimates,
which were derived utilizing numerous assumptions regarding future events,
including the continued availability of certain resources, third-party
modification plans and other factors.  There can be no assurance that these
estimates will be achieved and actual results could differ materially from those
anticipated.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        
The Company designs, manufactures and markets mixed signal integrated circuits
("ICs") primarily for timing and networking solutions for the PC industry and
also markets custom, application-specific ICs developed pursuant to product
development projects with selected customers.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The accompanying consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries, after elimination of all significant
intercompany accounts and transactions.  The effect of adjustments to the
Company's carrying values of subsidiaries resulting from their underlying equity
transactions is included in the Company's stockholders' equity.

Reporting Periods

In fiscal 1996 the Company changed its fiscal year to a 52/53 week operating
cycle that ends on the Saturday nearest June 30.  All of the reporting periods
presented herein represent a 52-week operating cycle.

Cash Equivalents

The Company considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents.  Cash and cash
equivalents at June 27, 1998 consist of cash, overnight retail repurchase
agreements (held in U.S. Treasury obligations), money market funds and
commercial paper.

Marketable Securities

Marketable securities at June 27, 1998, consist of debt and equity securities.
The Company adopted the provisions of Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities" ("Statement No. 115") in fiscal 1995.  Under Statement No. 115, the
Company classifies all of its debt securities as held to maturity and records
them at amortized cost. The Company's equity securities are classified as
trading securities and unrealized holding gains and losses are included in
earnings.

Inventory

Inventory is stated at the lower of standard cost, which approximates actual
cost (FIFO basis) or market.

Property, Plant and Equipment

Property and equipment are stated at cost.  Depreciation is computed on the
straight-line method over the estimated useful lives of the assets of generally
30 years for buildings and between 18 months and 10 years for all other
property, including equipment and building improvements.  Leasehold improvements
are amortized over the shorter of the lease term or the estimated useful life.

Goodwill

The purchase price in excess of the fair value of net assets acquired is
amortized on a straight-line basis over 7 years.  Accumulated amortization was
$0.3 million and $80,000 as of June 27, 1998 and June 28, 1997, respectively.
During the fourth quarter of 1997, the Company recorded an impairment loss of
$7.1 million, of which $3.9 million represented a goodwill write-off.  This
decision to record an 

                                       29
<PAGE>
 
impairment was based on the decline in the financial results of Voyetra and a
determination that the cash flows from the business would not be sufficient to
recover the carrying value of the Company's investment. See footnote 3 for
further details.

Carrying Value of Long-Term Assets

The Company evaluates the carrying value of long-term assets, including
goodwill, based upon current and anticipated undiscounted cash flows, and
recognizes an impairment loss when it is probable that such estimated cash flows
will be less than the carrying value of the asset.  Measurement of the amount of
impairment, if any, is based upon the difference between carrying value and
undiscounted cash flows.  The Company has adopted Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets Disposed of" (SFAS 121) in fiscal year ended
June 28, 1997.  See footnote 3 for a discussion of an impairment charge in the
Voyetra investment, which was recorded in the fourth quarter of fiscal 1997.

Revenue Recognition

Product sales are recognized as revenue upon shipment to the customer.
Estimated allowances are established to recognize the right of return from
selected customers.  Design revenue is recognized pursuant to development and
production contracts for custom ICs representing partial reimbursement of
research and development expenditures.

Concentration of Credit Risk

The Company sells its products primarily to original equipment manufacturers and
distributors in North America, Europe and the Pacific Rim.  The Company performs
ongoing credit evaluations of its customers and maintains reserves for potential
credit losses.  Concentrations of credit risk with respect to trade accounts
receivable from specific customers  is limited due to the large number of
customers and their dispersion across many geographic areas, however, there is a
substantial concentration in the personal computer industry. Refer to footnote
18 for geographic information.

Income Taxes

Income taxes are computed in accordance with Statement of Financial Accounting
Standards No. 109. The Company files a consolidated federal tax return with its
80% or more owned subsidiaries, which included Turtle Beach for the first five
months of fiscal 1997.

Earnings per Common Share

Basic earnings per share is computed using the weighted average number of common
shares outstanding during the period.   Diluted earnings per share is based on
the weighted average number of common shares and potential common stock ("PCS")
outstanding during the period.  PCS consists of stock options to purchase common
shares (using the treasury stock method based on average price  over the period
covered by the calculation), unless anti-dilutive.  No PCS were included in the
fiscal 1997 calculation since the effect would have been anti-dilutive.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions.
These estimates and assumptions affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the financial statements.  In addition, they affect the reported amounts of
revenue and expenses during the reporting period.  Actual results could differ
from these estimates and assumptions.

Accounting for Stock-based Compensation

The Company has adopted the disclosure provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
123"), which became effective for the year ended June 28, 1997. The Company
continues to apply APB 25 and related interpretation in accounting for its stock
options to employees and directors.  Refer to footnote 15 for pro forma
disclosures.

Reclassification of Accounts

Certain reclassifications have been made to conform prior year's balances to the
current year presentation.

New Pronouncements

The Company has not adopted Statement of Financial Accounting Standards ("SFAS")
No. 130, "Reporting Comprehensive Income", which will become effective for
fiscal year 1999.  The Company will adopt the requirements of this statement in
fiscal 1999.

The Company has not adopted SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information", which  becomes effective for fiscal year
1999. The Company will adopt the requirements of this statement in fiscal 1999.

In February, 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 132, "Employers' Disclosures about Pensions and other Post Retirement
Benefits".  This statement is effective for fiscal years beginning after
December 15, 1997.  The Company will adopt the requirements of this statement in
fiscal 1999.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities".  This statement is effective for all fiscal
quarters of all fiscal years beginning after June 15, 1999.  The Company has not
yet fully analyzed the impact of this statement on its financial statements.

(2)  ACQUISITIONS/MERGERS

On November 29, 1996 the Company signed an Agreement and Plan of Merger, (the
"Merger Agreement") to sell its approximately 87% interest in Turtle Beach
Systems, Inc. ("Turtle Beach") to Voyetra Technologies Inc. ("Voyetra"), in
exchange for an approximately 35% equity interest in Voyetra. Voyetra is a
supplier of music and audio software.  No gain or loss was initially recorded on
this transaction in accordance with APB 29 "Accounting for Nonmonetary
Transactions", which states that the exchange of similar productive assets not
held for sale in the ordinary course of business does not result in the
culmination of the earnings process.  The Company's proportionate share of
underlying equity in Voyetra was approximately $3.5 million.  The excess of the
Company's carrying value over their proportionate share of underlying equity was
approximately $4.3 million.  Subsequent to the transaction, the Company
accounted for its investment in Voyetra under the equity method of accounting.
In connection with the merger, the Company also entered into a Revolving Credit
Agreement and Note Arrangement (the " Revolving Credit Agreement") with Voyetra,
pursuant to which the Company agreed to make loans to Voyetra up to an aggregate
of $3.5 million, subject to certain covenants.    The Company recorded an
impairment loss on this investment in the fourth quarter of fiscal 1997.  (See
Disposition/Impairment footnote 3).

                                       31
<PAGE>
 
On February 28, 1997 the Company acquired all the capital stock of  MicroClock,
Inc. ("MicroClock"), a  producer of clock synthesizer integrated circuits for
multimedia applications, for approximately $16.4 million, consisting of $6.4
million in cash and 608,504 shares of ICS common stock.  The Company's shares
exchanged in the transaction were restricted from sale for one year, therefore,
the shares were valued at a discount from the closing price on the date of
issuance based on an independent valuation. The acquisition was accounted for
under the purchase method of accounting and resulted in a charge of $11.2
million related to the write-off of in-process research and  development costs
and the recording of goodwill of $1.7 million, which is being amortized over 7
years.  Revenues and results of operations of MicroClock were not significant to
the Company's consolidated statement of operations for the year ended June 28,
1997, and accordingly, proforma information as if the transaction had occurred
on June 29, 1996, has not been presented.

(3)  DISPOSITIONS/IMPAIRMENT

In the first quarter of fiscal 1997, the Company sold its Galaxy Power, Inc.
subsidiary, which owned the assets related to the battery charge controller
product line, for $0.8 million to Edward H. Arnold, former Chairman and CEO of
the Company.  The purchase consideration was satisfied by reacquisition  of
68,387 shares of the Company's stock held by Arnold and was based on a valuation
made by an independent appraiser.

During the third quarter of fiscal 1997, the Company implemented a plan, with
approval by the Board of Directors, to  dispose of  its majority   interest  in
its subsidiary, ARK  Logic, within   a 12-month period.  Accordingly, the
Company presented ARK Logic as a discontinued operations and all prior periods
have been restated to reflect this presentation. In connection with these
events, the Company recorded a charge of $1.5 million in the third quarter
fiscal 1997, including severance and facility termination costs. Subsequently,
the Company sold approximately 80% of its holdings in ARK Logic to Vision 2000
Ventures, Ltd. ("Vision 2000") for which a gain of $0.9 million, including the
reversal of severance and facility termination accruals, was recorded.  The sale
and purchase agreement required 20% of the sales price to be held in escrow for
two years.  The amounts from discontinued operations are not tax effected, as
ARK Logic was not consolidated for tax purposes and ARK Logic has net operating
loss carryforwards.  Revenues from ARK Logic for fiscal 1997 and 1996 were $1.8
million and $10.2 million, respectively.

During the fourth quarter of fiscal 1997 the Company determined that significant
events and changes in circumstances had occurred subsequent to the Voyetra
transaction  that indicated it was probable that its investment in Voyetra would
not be recoverable.  In the opinion of the Company's management, Voyetra was
experiencing an adverse shift in the fundamentals of its business which resulted
in deteriorating gross profit margins and a substantial increase in operating
losses.  In addition, during the fourth quarter of fiscal 1997 the Company
notified Voyetra that they had violated certain covenants and were in default
under the Revolving Credit Agreement.   As such, the Company concluded that it
was under no obligation to provide financing under the Revolving Credit
Agreement.  As a result of these significant events in the fourth quarter of
fiscal 1997, management of the Company estimated that the undiscounted cash
flows anticipated for Voyetra would not be sufficient to recover the carrying
value of the Company's investment and a write-down to fair  value was  required.
Consequently, in the fourth quarter of fiscal 1997, the Company recorded an
impairment loss of $7.1 million on its investment in Voyetra which is included
in the Statement of Operations as Impairment in equity investment.  In the
second quarter of fiscal 1998, Voyetra filed a complaint in the Supreme Court of
the State of New York against the Company.  At the end of the second quarter,
the Company and Voyetra reached a settlement.  Voyetra would release the Company
from all claims and all obligations with respect to the 

                                       32
<PAGE>
 
Voyetra/Turtle Beach merger agreement in exchange for assumption of certain
liabilities of Turtle Beach, a $200,000 cash payment and return of Voyetra stock
held by the Company. As of June 27, 1998, the Company has settled these
obligations and returned the Voyetra stock.

(4)  PURCHASE COMMITMENTS

During fiscal 1998, under an existing wafer supply contract with Chartered
Semiconductor Manufacturing PTE Ltd.  ("CSM")  the Company advanced the final
$2.0 million installment of its deposit with CSM whereby CSM would supply an
agreed minimum quarterly quantity of wafers over a five-year period from April
1996 through December 2000 at favorable prices.  This non-interest bearing
deposit is recorded as a long term asset under the caption "Deposits on purchase
contract" and will be progressively repaid from January 1, 1998, as wafers are
purchased. As of June 27, 1998, CSM has repaid $2.1 million of the Company's
deposit.   As of June 27, 1998 and June 28, 1997 amounts due from CSM were $7.9
million and $8.0 million respectively. The Company had previously entered into a
similar agreement with American Microsystems, Inc., ("AMI") by which it placed a
$5.5 million deposit which has been progressively repaid as wafer purchases were
made.   The Company received $2.6 million from AMI in fiscal 1998 extinguishing
the balance of any outstanding deposit at AMI.

(5)  OTHER AGREEMENTS

In fiscal 1998, the Company entered into a non-transferable and non-exclusive
license with Philips Electronics to the Company to use their technical
information for data transmission systems.  In consideration of the licenses and
rights granted, the Company, during fiscal 1998, has paid and accrued
approximately $0.5 million in royalty fees.

(6)  MARKETABLE SECURITIES

The Company invests in debt securities which are recorded as held to maturity.
The estimated fair value of each investment approximates the cost, and
therefore, there were no unrealized gains or losses as of June 27, 1998 and June
28, 1997.  The Company also invests in equity securities which are recorded at
trading securities.  The securities are recorded at market value.  The company
recorded unrealized losses of approximately $.1 million in the statement of
operations for fiscal 1998.  There were no unrealized gains or losses as of June
28, 1997.  Proceeds from the sale or maturity of the investments were $34.3
million and $11.3 million in fiscal 1998 and fiscal 1997, respectively.  All
investments are due within on year and therefore, are classified as current
assets at June 27, 1998.

(10) DEBT

In the fourth quarter of fiscal 1998, the Company renegotiated its
revolving/term loan credit facility with a commercial bank to extend the
expiration to December 31, 1999.  The facility is subject to certain covenants,
including the maintenance of certain financial ratios, minimum tangible net
worth requirements, restrictions on the magnitude of stock repurchases and
payment of cash dividends. The Company was in compliance with all covenants as
of June 27, 1998.  On June 27, 1998, the Company had no outstanding borrowings
under this facility.  The facility is subject to a commitment fee equal to 1/8%
on the unused portion due and payable quarterly in arrears.

The line of credit available for future borrowings at June 27, 1998 was $20.0
million; which includes $3.0 million reserved for outstanding letters of credit.
Advances under the revolving portion of the facility bear interest pegged at
either the bank's prime rate or the LIBOR rate.

(12) FAIR VALUE OF FINANCIAL INSTRUMENTS

Estimated fair value of financial instruments is provided in accordance with the
requirements of SFAS No. 107, "Disclosures About Fair Value of Financial
Instruments".  The estimated fair value amounts have been determined by the
Company using available market information and appropriate methodologies.
However, considerable judgment is necessarily required in interpreting market
data to develop the estimates of fair value.

                                       35
<PAGE>
 
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:

     Cash and cash equivalents, accounts receivable and accounts payable - The
     carrying amounts of these items approximate their fair values at June 27,
     1998 due to the short-term maturities of these instruments.

     Marketable securities - The estimated fair value of each held to maturity
     investment approximates the amortized cost and as such no unrealized gain
     or loss has been recorded.

     Long-term debt - Interest rates that are currently available to the Company
     for issuance of debt with similar terms and remaining maturities are used
     to estimate fair value for debt issues for which quoted market prices are
     not available.

     The carrying value of this item is not materially different from its fair
     value on June 27, 1998.

</TABLE>

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which temporary differences representing net future deductible amounts become
deductible.

Management considers the scheduled reversal of deferred tax liabilities,
projected future taxable income, potential limitations with respect to the
utilization of loss carry forwards, and tax planning strategies in making this
assessment. Based upon the projections for future taxable income over the
periods which deferred tax assets are deductible and the potential limitations
of loss and credit carry forwards, management believes it is more likely than
not the Company will realize these deductible differences, net of existing
valuation allowances (both federal and state) at June 27, 1998. The Company will
periodically reassess and re-evaluate the status of its recorded deferred tax
assets.

The per share weighted-average fair value of stock options issued by the Company
were $14.77, $6.57, and $6.69 for fiscal 1998, 1997 and 1996 respectively.

The following assumptions were used by the Company to determine the fair value
of stock options granted using the Black-Scholes option-pricing model:

<TABLE>

Dividend yield                                          0%

Average expected option life                       4 years
Risk-free interest rate                       5.34% - 6.4%
</TABLE>

Pro forma net income (loss) reflects only options granted in fiscal 1998, 1997
and 1996.  Therefore, the full impact of calculating compensation cost for stock
options under SFAS No.123 is not reflected in the pro forma net income (loss)
amounts presented above because compensation cost is reflected over an option's
vesting period, and compensation cost for options granted prior to July 1, 1995
is not considered.

(16) EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
128").  SFAS 128 was issued to simplify the computation of EPS and to make U.S.
standards more compatible with the EPS standards of other countries and that of
the International Accounting Standards Committee.  SFAS 128 is effective for
financial statements for periods ending after December 15, 1997.  The Company
adopted SFAS 128 in the second quarter of fiscal 1998.

The calculations of Earnings Per Share (EPS) were (in thousands except per share
amounts):

(17)    TREASURY STOCK

In January 1998, the Company's Board of Directors authorized a revised program
to repurchase up to 1.5 million shares of the Company's common stock.  The
timing and amount of shares repurchased will be determined at the discretion of
the Company's management.  As of June 27, 1998, the Company has repurchased an
aggregate of 1.3 million shares valued at $23.9 million using the cost method.
In connection with the sale of its battery charge controller product line, the
Company received 68,387

                                       41
<PAGE>
 
shares of the Company's common stock valued at $11.537 per share, which is
included in treasury stock (see Related Party footnote 19).  In connection with
the Company's acquisition of MicroClock, the Company issued 0.6 million shares
which were taken from treasury stock (see Acquisition/Merger footnote 2).  As of
June 27, 1998, the Company had 0.8 million shares in treasury stock valued at
$16.7 million, held at an average cost of $21.64.

(18) BUSINESS SEGMENT AND GEOGRAPHIC INFORMATION

The Company operates primarily within one business segment which is the design,
development and marketing of integrated circuits.  Foreign sales consist of
shipments primarily to the Pacific Rim and Europe and which were approximately
58.8%, 60.3% and 46.8% of revenues in fiscal 1998, 1997 and 1996 respectively.

(19) RELATED PARTY TRANSACTIONS

In the third quarter of fiscal 1998, the Company entered into a severance
agreement with Stavro Prodromou, the former President and Chief Executive
Officer.  Dr. Prodromou received $135,000 in cash severance and  health benefits
at the time of his departure, and was granted up to a one year period  to
exercise 125,000 of his stock options.  His remaining options were canceled.

On May 6, 1998, the Company entered into an employment agreement with Henry
Boreen to serve as the Company's interim CEO until September 11, 1998.  The term
of this agreement may be extended by the Company at its sole option. Mr.
Boreen's base compensation is $10,000    per  month, plus a grant  of  50,000
stock  options  at an exercise price at fair market price at date of grant,
which  immediately vested.   On September 14, 1998, the Company made an
amendment to this agreement to extend the term to December 31, 1998.  The
amendment also increased Mr. Boreen's base compensation to $12,000 per month
plus a grant of 30,000 stock options at an exercise price at fair value at the
date of grant, which immediately vest.

On May 11, 1998, each non-employee director entered into a consulting agreement
with the Company for management consulting services.  The term of each of the
consulting agreement ends on December 31, 1998, and to the extent service (not
to exceed ten days per month) of any such director were to be retained, he would
receive cash compensation of $2,000 per day.

On September 25, 1996, the Company sold its battery charge controller product
line to Edward H. Arnold, a former director and former Chief Executive Officer
of the Company. Although the Company had been involved in this product line
since 1991, it was not considered part of the Company's core business and the
associated products did not materially contribute to the Company's revenue. In
making this sale the Company determined that further investment in such a
product line was not consistent with the strategic direction of the Company.
Under the terms of such tax-free sale, Mr. Arnold acquired all outstanding
shares of the Company's wholly-owned subsidiary which owned the intellectual
property rights and working capital assets of this product in exchange for
68,387 shares of the Company's common stock valued at $11.537 per share (the
average closing price for the 10 days prior to the sale). The sale price of $0.8
million was based upon a valuation made by an independent appraiser and involved
a premium over such valuation. In addition, the Company will receive a royalty
of 2% for all sales during the three-year period after September 25, 1996 as
consideration for a trademark license associated with this product line. The
Company has recorded the gain in the statement of operations as follows: the
battery charge controller inventory sold was recorded as 

                                       42
<PAGE>
 
revenue ($0.6 million) with its corresponding costs in cost of sales ($0.3
million), and the gain on the remaining assets is recorded as other income ($0.2
million).

In the first quarter of fiscal 1997, the Company and David Sear, the former
President and Chief Executive Officer, entered into a severance agreement.   The
Company recorded a charge of $0.3 million in connection with this agreement.

In the first quarter of fiscal 1997, the Company and Henry I. Boreen, Chairman
of the Board, entered into an employment agreement as Interim Chief Executive
Officer.  For his services in this capacity, Mr. Boreen received a grant of
75,000 stock options at an exercise price of $10.38 per share which was equal to
the closing price on the date of grant, and which option has a term of ten years
and became exercisable in monthly installments over the six month period
following the date of grant.

(20) RISKS ASSOCIATED WITH INTERNATIONAL BUSINESS ACTIVITIES

For the fiscal years 1998, 1997 and 1996, the Company generated approximately
58.8%, 60.3% and 46.8% of its net sales, respectively, from international
markets.  These sales were generated primarily from the Company's customers in
the Pacific Rim region and included sales to foreign corporations, as well as to
foreign subsidiaries of U.S. corporations.  The Company estimates that in fiscal
1998, approximately  one-half of the Company's sales in international markets
were to foreign corporations, with the bulk of them being in Taiwan.

In addition, two of the Company's wafer suppliers and all of the Company's
assemblers are located in the Pacific Rim.  Several countries in this region
have experienced currency devaluation and/or difficulties in financing short-
term obligations.  There can be no assurance that the effect of this economic
crisis on the Company's wafer suppliers will not impact the Company's wafer
supply or assembly operations, or that the effect on the Company's customers in
that region will not adversely affect both the demand for the Company's products
and the collectivity of receivables.  See "Manufacturing".

The Company's international business activities in general are subject to a
variety of potential risks resulting from certain political, economic and other
uncertainties including, without limitation, political risks relating to a
substantial number of the Company's customers being in Taiwan.  Certain aspects
of the Company's operations are subject to governmental regulations in the
countries in which the Company does business, including those relating to
currency conversion and repatriation, taxation of its earnings and earnings of
its personnel, and its use of local employees and suppliers.  The Company's
operations are also subject to the risk of changes in laws and policies in the
various jurisdictions in which the Company does business which  may  impose
restrictions  on the  Company.  The Company cannot determine to what extent
future operations and earnings of the Company may be effected by new laws, new
regulations, changes in or new interpretations of existing laws or regulations
or other consequences of doing business outside the U.S.

The Company's activities outside the U.S. are subject to additional risks
associated with fluctuating currency values and exchange rates, hard currency
shortages and controls on currency change. Additionally, worldwide semiconductor
pricing is influenced by currency fluctuations and the recent devaluation of the
currencies of several countries in the Pacific Rim could have a significant
impact on the prices of the Company's products if its competitors offer products
at significantly lower prices in an effort to maximize cash flows to finance
short-term, dollar denominated obligations; such devaluations 

                                       43
<PAGE>
 
could also impact the competitive position of the Company's customers in Taiwan
and elsewhere, which could impact the Company's sales.

(21) MAJOR CUSTOMERS

During fiscal 1998 and 1997, no customer represented 10% or more of the
Company's revenues. During fiscal 1996 shipments to Intel (including all Intel
subcontractors) accounted for 11% of the Company's consolidated revenue.

(b)  Reports on Form 8-K

     On April 23, 1998, the Company filed a current report on Form 8-K, which
was included as an exhibit to the third quarter earnings release.  The earnings
release disclosed that the Company had experienced increased competition in the
market for single channel 10/100mb LAN transceivers, which led to cancellation
of orders and severe price erosion for this product line.  While recent market
acceptance of several new frequency timing products for multimedia and
communication applications has been positive, the new frequency timing products
did not deliver sufficient revenue and earnings in the fourth quarter to offset
the decline from networking transceivers.

                              SEVERANCE AGREEMENT
                              --------- ---------

     This Severance Agreement (the "Agreement") is made on this 20th day of
March 1998 (the "Effective Date"), by and among Integrated Circuits Systems,
Inc., a Pennsylvania corporation (the "Company"), and Stavro E. Prodromou, Ph.D.
("Employee").

     Whereas, Employee has served as the President and Chief Executive Officer
of the Company:

     Whereas, by mutual consent Employee is resigning as President and Chief
Executive Officer;

     Whereas, the parties hereto desire to enter into this Agreement on the date
hereof to set forth their agreement with respect to said resignation and certain
other matters in connection therewith upon the terms and conditions hereinafter
set forth; and

     Whereas, the parties desire that this Agreement supersede any agreement,
arrangement or understanding with respect to the terms of the employment of
Employee by the Company binding on Employee and the Company, except as referred
to in Section 13(a) hereof.

     NOW THEREFORE, in consideration of the covenants and conditions set forth
in this Agreement, the parties, intending to be legally bound, agree as follows:

     1.   Termination of Employment.
          -------------- ---------- 

               (a)  Employee hereby voluntarily and irrevocably resigns from all
of his positions as a director, officer, employee, partner, principal, agent,
representative, consultant or otherwise, with or in (i) the Company and its
affiliates, or (ii) any other corporation, partnership or other entity in
respect of which he was serving at the request of the Company, in each case
effective as of 5:00 p.m., Philadelphia time, on the Effective Date. Employee
acknowledges that his employment relationship with the Company was permanently
and irrevocably severed as of the Effective Date and agrees that the Company and
its affiliates have no obligation, contractual or otherwise, to rehire, re-
employ, recall or rehire him in the future.

               (b)  Employee further acknowledges and agrees that payments made
or to be made and benefits provided or to be provided hereunder are in lieu of
any and all compensation and benefits of any nature whatsoever due to Employee
under the terms of any agreement, arrangement or understanding (whether written
or oral) binding upon the Company and Employee.
<PAGE>
 
          2.   Severance Compensation. In full consideration of Employee's 
               ----------------------    
execution of this Agreement and his agreement to be legally bound by its terms,
the Company has paid or agrees to pay Employee the following amounts, and has
provided or agrees to provide the following benefits to Employee:

               (a)  The company has paid Employee, and Employee hereby
acknowledges receipt of the sum of $120,000 (minus all payroll deductions
required by law or authorized by Employee). In addition, Employee shall promptly
receive payment in respect of unused vacation days to which Employee is
entitled. The Company has paid employee, and Employee hereby acknowledges
receipt of the sum of $15,000 (minus all payroll deductions required by law or
authorized by Employee) in lieu of relocation expenses.

               (b)  Employee acknowledges and agrees that he has earned and been
paid in full bonus under the Company's bonus plan in respect of the period ended
December 31, 1997. The Company agrees that Employee will be eligible to receive
a bonus in respect of the quarter ending March 28, 1998 to the same extent as
would otherwise have been the case had Employee remained an employee of the
Company through such date, but no representation of any nature is made by the
Company as to whether a bonus will be earned by Employee in respect of such
period or the amount thereof. Employee and Company agree that all determinations
in that regard shall be made solely by the Compensation Committee of the board
of directors of the Company which shall be determined in its discretion in a
manner that is fair, consistent and equitable with bonuses granted to Employee
and to other employees of similar responsibility and bonus eligibility, during
the same and prior periods, and such determination shall be final and binding
upon Employee.

               (c)  Employee acknowledges that the period within which the
Company must make available the purchase of health insurance under the
Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") will commence
as of the Effective Date. If and only to the extent permitted under the
Company's health insurance plans, the Company shall provide Employee until
September 30, 1998 with health insurance coverage of the nature (and subject to
the same deductibles and cost-sharing features) as may be provided by the
Company to its senior executive officers during such period. If the Company is
unable to include Employee in such health insurance plan during any portion of
such period and Employee instead purchases health insurance from the Company
under COBRA, then the Company will pay Employee during such portion of this
period an amount equal to 160% of the cost of obtaining such insurance from the
Company pursuant to COBRA. Notwithstanding the foregoing, this section shall no
longer be applicable when Employee is employed by a new employer that provides
health insurance to its employees on a comparable cost-sharing basis to that
provided by the Company. Except as expressly stated above, Employee shall not be
entitled to any benefits provided to employees of the Company after the
Effective Date.

               (d)  Employee shall be reimbursed for the reasonable business
expenses (including certain relocation expenses) incurred by him prior to the
Effective Date in connection with the performance of services as president and
chief executive officer of the Company upon presentation of an itemized account
and written proof of such expenses in accordance with the Company's policies.

                                      -2-
<PAGE>
 
               (e)  The Company has previously granted Employee options to
acquire a total of 250,000 shares of the Company's common stock (the "Stock
Options") pursuant to the Company's 1992 Stock Option Plan, as amended (the
"1992 Plan"). Notwithstanding Section 12.3 of the 1992 Plan, but subject in all
respects to (i) all of the other provisions of the 1992 Plan and the option
agreements pursuant to which the Stock Options were granted and (ii) compliance
by Employee after the Effective Date with the provisions of this Agreement, the
Company and the Employee agree that the first 125,000 shares of the Stock
Options shall vest as scheduled (62,500 options on April 2, 1998 and the
remaining 62,500 options on April 2, 1999) and be exercisable in full through
the close of business, Philadelphia time, on October 2, 1999. The Company and
Employee agree that the remaining 125,000 options will expire immediately.
Employee acknowledges that, as a result of the foregoing, if any of the options
were intended to qualify as incentive stock options, such Stock Options will no
longer so qualify and will be treated as nonqualified stock options.

               (t)  Employee alone, and not the Company, will be solely
responsible for payment of all federal, state and local taxes required to be
paid by him in respect of the payments to be made and benefits to be provided to
him under this Agreement, and Employee acknowledges that such payments and
benefits may be subject to tax withholding.

          3.   Return of Company Property. By April 19, 1998, Employee will
               --------------------------    
return to the Company all lists, records, documents, credit cards, building
passes, computers and other materials or property of any nature in his
possession unless mutual arrangements have been made for Employee to purchase
certain equipment, custody or control which are or were owned by the Company or
any of its subsidiaries or affiliates, and Employee will not retain or deliver
to any other persons or entities copies thereof or permit any copies thereof to
be made by any other person or entity. The Company grants to Employee the right
to purchase the Hitachi notebook computer used by Employee for a sum of
$1,000.00, which right will expire on before April 19, 1998. The Company further
agrees to forward all personal mail and package deliveries to Employee, and to
provide and maintain electronic mail and voice mail accounts and services in its
Valley Forge and San Jose facilities for the exclusive use of Employee from the
Effective Date until September 30, 1998.

          4.   General Release
               ---------------

               (a)  In consideration of the foregoing, (including without
limitation the promises and payments as described in Section 2 above, which may
be in excess of that to which Employee would have otherwise been entitled upon
termination of employment), Employee hereby knowingly, willingly and voluntarily
remises, waives, releases and forever discharges the Company and its
subsidiaries and affiliates, the directors, officers, employees, advisors and

Law, in each case as in effect on or prior to the Effective Date, and (ii) the
rights, if any, of Employee under any directors and officers insurance policy

Effective Date.

               (b)  In consideration of Employee's release and of the premises
and agreements set forth in this Agreement, Company hereby knowingly, willingly,

has from or by reason of any cause, matter or thing whatsoever from the
beginning of his employment with the Company to the Effective Date, and
including, without in any way limiting the generality of the foregoing, any and
all matters relating to his employment by the Company, and any and all claims
under any federal, state or local law, and any common law claims and all claims
for counsel fees and costs, excepting only claims against the Employee relating
to his obligations under this Agreement.

               (c)  Each party represents that it is their intention in
executing this Agreement that it shall be effective as a part of each and every
claim, demand, suit, action, cause of action, and debt which it may have against
Releasees, and Employee Releasees, respectively; and in furtherance of this
intention each party

HEREBY EXPRESSLY WAIVES ANY AND ALL RIGHTS AND BENEFITS CONFERRED UPON IT BY THE
PROVISIONS OF SECITON 1542 OF THE CIVIL CODE OF CALIFORNIA WHICH PROVIDES AS
FOLLOWS:

geographic, product or service, or other limitations permitted by applicable
law.

                             EMPLOYMENT AGREEMENT
                             --------------------
                                        
     EMPLOYMENT AGREEMENT (the "Agreement") dated as of May 6, 1998 by and
between INTEGRATED CIRCUIT SYSTEMS, INC., a Pennsylvania corporation (the
"Company") and HENRY I. BOREEN ("Employee").

     1.   EMPLOYMENT. The Company hereby employs Employee as its Chief Executive
Officer (the "Position"), and Employee hereby accepts such employment and agrees
to perform Employee's duties and responsibilities hereunder, in accordance with
the terms and conditions hereinafter set forth.

          1.1  EMPLOYMENT TERM. The period of Employee's employment by the
Company pursuant to this Agreement (the "Employment Term") shall commence _____
and shall continue for a six-month period thereafter, ending ______, unless
terminated prior thereto in accordance with Section 5 hereof; provided, however,
that the Employment Term shall automatically be extended by the Company, at its
sole option.

          1.2  DUTIES AND RESPONSIBILITIES.

          (a)  During the Employment Term, Employee shall serve in the

previously identified Position and shall perform all duties and accept all
responsibilities incident to such Position or as may be assigned to him by the
Company's Board of Directors.

          (b)  Employee represents to the Company that Employee is not subject
to or party to (and except for the present Agreement and any other agreement
with the Company, Employee agrees during the Employment Term not to become
subject to or a party to) any employment agreement, non-competition covenant,
non-disclosure agreement or other agreement, covenant, understanding or
restriction of any nature which would prohibit Employee from executing this
Agreement and performing fully Employee's duties and responsibilities hereunder,
or which would in any manner, directly
<PAGE>
 
or indirectly, limit or affect the duties and responsibilities which may now or
in the future be assigned to Employee by the Company, including without
limitation any duties and responsibilities relating to the business in which the
Company (including its subsidiaries) is engaged during the Employment Term or
for which Employee has notice during such Employment Term that the Company is
planning to be engaged within the six (6) month period following any expiration
or termination of this Agreement (the "Business" of the Company).

          1.3  EXTENT OF SERVICE.  During the Employment Term, Employee agrees
to use best efforts to carry out the duties and responsibilities under Section
1.2 hereof and to devote full time, attention and energy thereto.  Employee
further agrees not to work either on a part time or independent contracting
basis, or serve as a director, officer or in any other capacity, or to otherwise
become engage in any business activity or enterprise (including any material
investment therein) during the Employment Term without the prior disclosure to
and consent of the Company in accordance with its policies.  The foregoing shall
not, however, be construed as prohibiting the ownership of not more than 5% of
any class of securities registered pursuant to the Securities Exchange Act of
1934, as amended, provided that such ownership represents solely a passive
investment and the Employee does not in any way manage, control, perform
services for or otherwise take any role therein which may create a conflict of
interest or otherwise interfere with Employee's ability to discharge Employee's
duties and responsibilities to the Company.

          1.4  BASE COMPENSATION.

          (a)  For all the services rendered by Employee hereunder, the Company
shall pay Employee a salary at a monthly rate of Ten Thousand ($10,000.00)
dollars per month.

          (b)  During the Employment Term, Employee shall also be entitled to
participate in such vacation pay, retirement, other fringe benefit plans and
prerequisites, if any,  as may be duly authorized from time to time by the
Company, in its sole discretion, the terms and provisions of which plans and
prerequisites shall also be in the sole discretion of the Company, which terms
and provisions shall be controlling with 

                                       2
<PAGE>
 
respect to the manner in which any such benefit or prerequisite is earned,
accrued, vested, paid or otherwise available.

         1.5  INCENTIVE COMPENSATION. In addition to the compensation set forth
in Section 1.4 hereof, Employee shall be entitled to participate in such
incentive compensation plans, if any, as may be applicable to its management
level employees, and as may be duly established from time to time in respect to
the Employment Term by the Company in its sole discretion, which terms and
provisions shall be controlling with respect to the manner in which any such
incentive compensation is earned, accrued, vested, paid or otherwise made
available to its participants.

     2.  EXPENSES. Employee shall be reimbursed for the reasonable business
expenses incurred by Employee in connection with Employee's performance of
services hereunder during the Employment Term upon presentation of an itemized
account and written proof of such expenses in accordance with policies duly
established by the Company. Termination of Employee's Employment Term in
accordance with Section 5 of this Agreement shall not terminate the obligation
to reimburse expenses properly incurred prior to the date of such termination in
accordance with the Company's policies.

     3.  CONFIDENTIAL INFORMATION; NON-SOLICITATION AND NON-COMPETITION.

Employee acknowledges and agrees that (i) Employee has executed or will execute
the Company's standard forms of confidential information (the "Confidentiality
Agreements"), (ii) during Employee's employment and for a period of eighteen
(18) months after the employment of Employee by Company has ended, Employee will
not, directly or indirectly, solicit the employment of any person who was
employed by the Company or any of its subsidiaries on a full or part time basis
at the time of Employee's employment, unless such person was (1) involuntarily
discharged by the Company or such subsidiary or (2) voluntarily terminated his
or her relationship with the Company prior to Employee's termination and (iii)
during Employee's employment and for a twelve (12) month period immediately
following any termination of such employment, 

                                       3
<PAGE>
 
without the prior written consent of the Company, directly or indirectly, engage
in, participate in, have any interest on behalf of Employee or others in, or
permit Employee's name to be used with any corporation or other entity or
enterprise which competes with the Business in the geographical areas where the
Company conducts such Business, whether as an employee, officer, director,
agent, consultant, investor, security holder, creditor, guarantor, partner,
joint venturer, beneficiary under a trust or otherwise (subparagraphs (ii) and
(iii) are collectively the "Restrictive Covenants").

     4.  ARBITRATION AND EQUITABLE RELIEF.

     (a) Employee acknowledges that the restrictions contained in the
Confidentiality Agreements and Restrictive Covenants are reasonable and
necessary to protect the legitimate interests of the Company and its affiliates,
that the Company would not have entered into this Agreement in the absence of
such restrictions, and that any violation of any provision of the
Confidentiality Agreements or Restrictive Covenants will result in irreparable
injury to the Company. Employee represents that Employee's experience and
capabilities are such that the restrictions contained in the Confidentiality
Agreements and Restrictive Covenants will not prevent Employee from obtaining
employment or otherwise earning a living at the same general level of economic
benefit as anticipated by this Agreement. Employee further represents and
acknowledges that (i) as a condition of entering into this Agreement, Employee
has reconfirmed, and does hereby reconfirm that all of the provisions of the
Confidentiality Agreements and Restrictive Covenants are and will continue to be
valid and binding upon Employee, and enforceable against Employee to the full
extent set forth therein, (ii) Employee has been advised by the Company to
consult Employee's own legal counsel in respect of this Agreement and the
statements set forth herein and in respect of the Confidentiality Agreements and
Restrictive Covenants, and (iii) that Employee has, prior to execution of this
Agreement and the Confidentiality Agreements, reviewed this Agreement, the
Confidentiality Agreements and the Restrictive Covenants with Employee's
counsel.

     (b) Except as provided in Section 4(c) below, Employee and the Company
agree that any dispute or controversy arising out of or relating to any
interpretation, 

                                       4
<PAGE>
 
construction, performance or breach of this Agreement, shall be exclusively
settled by arbitration to be held in the county and state set forth in the
following paragraph, in accordance with the National Rules for the Resolution of
Employment Disputes as then in effect of the American Arbitration Association. A
panel of three arbitrators shall be chosen in accordance with such rules to
conduct the arbitration, unless Employee and the Company agree in writing to
have such disputes settled by a single arbitrator. The arbitrators may grant
injunctions or other relief in such dispute or controversy, but shall have no
authority to set aside or review any decision of the board of directors or its
compensation committee which under the terms of this Agreement or the
controlling Company benefit plan or policy are discretionary with the Company,
unless such decisions are shown by clear and convincing evidence to have been
made in bad faith. The decision of the arbitrators shall be final, conclusive
and binding on the parties to the arbitration. Judgment may be entered on the
arbitrators' decision in any court having jurisdiction. The Company and Employee
shall each pay one-half of the costs and expenses of such arbitration, and each
of the Company and Employee shall separately pay its counsel fees and expenses,
subject, however, to the right of the arbitrators to assess costs and expenses
in circumstances where such arbitrators deem it appropriate to do so. If a party
shall attempt to vacate or appeal from an arbitration award or obtain an order
staying the arbitration, and such party (the "non-prevailing party") is
unsuccessful in obtaining such judicial relief, then the non-prevailing party
will be responsible for all attorney's fees and costs incurred by the other
party in connection therewith.

     (c)  Employee agrees that the Company shall be entitled (in addition to
seeking relief pursuant to an arbitration pursuant to (b) above) to preliminary
and permanent injunctive relief, without the necessity of proving actual
damages, as well as an equitable accounting of all earnings, profits and other
benefits arising from any violation of the Confidentiality Agreements or
Restrictive Covenants, which rights shall be cumulative and in addition to any
other rights or remedies to which the Company may be entitled as set forth in
the Confidentiality Agreements or otherwise.  Employee irrevocably and
unconditionally (i) agrees that any such suit, action or other legal proceeding
commenced by the Company may be brought in the United States District Court for,
or in any court of 

                                       5
<PAGE>
 
general jurisdiction in the county of Montgomery, Commonwealth of Pennsylvania,
(ii) consents to the non-exclusive jurisdiction of any such court in any such
suit, action or proceeding, and (iii) waives any objection which Employee may
have to the laying of venue of any such suit, action or proceeding in any such
court. Employee also irrevocably and unconditionally consents to the service of
any process, pleadings, notices or other papers in a manner permitted by the
notice provisions of Section 10 hereof.

     (d)  In the event that any of the provisions of the Confidentiality
Agreements or Restrictive Covenants should ever be held or adjudicated to exceed
the time, geographic, product or service, or other limitations permitted by
applicable law in any jurisdiction, then such provisions shall be deemed
reformed in such jurisdiction to the maximum time, geographic, product or
service, or other limitations permitted by applicable law.

     (e)  Employee agrees that Employee will provide, and that the Company may
similarly provide, a copy of the Confidentiality Agreements and Restrictive
Covenants to any business or enterprise (i) which Employee may directly or
indirectly own, manage, operate, finance, join, control or participate in the
ownership, management, operation, financing, control or control of, or (ii) with
which Employee may be connected with as an officer, director, employee, partner,
principal, agent, representative, consultant or otherwise, or in connection with
which Employee may use or permit Employee's name to be used.

     5.   TERMINATION. The Employment Term shall terminate prior to its
expiration as set forth in Section 1.1 above, and Employee's employment by the
Company shall be terminated, upon the occurrence of any of the following events
(and in accordance with the following provisions associated with such events):

     5.1. DISABILITY. In the event that Employee is unable fully to perform
Employee's duties and responsibilities hereunder to the full extent required by
the board of directors of the Company by reason of illness, injury or incapacity
for more than ninety (90) days, during which time Employee shall continue to be
compensated as provided in Section 1.4 hereof (less any payments due Employee
under disability benefit 

                                       6
<PAGE>
 
programs, including Social Security disability, worker's compensation and
disability retirement benefits), the Employment Term may be terminated by the
Company, and the Company shall have no further liability or obligation to
Employee for compensation hereunder; provided, however, that Employee will be
entitled to receive the payments prescribed under any disability benefit plan
which may be in effect for employees of the Company and in which Employee
participated at the date of such disability, and a pro-rata portion to the date
of disability of any earned incentive compensation, if any, referred to in
Section 1.5 hereof in respect of the fiscal year during which Employee first
became disabled. In the event of any dispute under this Section 5.1 and to the
extent determined by the Company to be job-related and consistent with business
necessity, Employee shall submit to a physical examination by a licensed
physician selected by the Company.

     5.2. DEATH. In the event that Employee dies during the Employment Term,
the Company shall pay to Employee's executors, legal representatives or
administrators an amount equal to the installment of Employee's Monthly Salary
set forth in Section 1.4 hereof for the month in which Employee dies, and a pro-
rata portion to the date of such death of any earned incentive compensation, if
any, referred to in Section 1.5 hereof in respect of the fiscal year during
which Employee died, and thereafter the Company shall have no further liability
or obligation hereunder to Employee's executors, legal representatives,
administrators, heirs or assigns or any other person claiming under or through
him; provided, however, that Employee's estate or designated beneficiaries shall
be entitled to receive the payments prescribed for such recipients under any
death benefit plan which may be in effect for employees of the Company and in
which Employee participated at the date of such death.

     5.3. CAUSE. Nothing in this Agreement shall be construed to prevent
termination of the Employment Term by the Company at any time for "cause."  For
purposes of this Agreement, "cause" shall mean (a) dishonesty, wanton or willful
misconduct, commission of a crime involving moral turpitude, substance abuse,
misappropriation of funds, disparagement of the Company (or its management or
employees), or (b) failure of 

                                       7
<PAGE>
 
Employee to perform, observe and fully comply during the Employment Term with
any of the terms or provisions of this Agreement or the lawful directives of the
Company, or at any time any of the terms or provisions of the Confidentiality
Agreements or Restrictive Covenants, or any other proper cause determined in
good faith by the Company; provided, however, that Employee's conduct shall not
constitute "cause" within the meaning of (b) above unless and until (i) the
Company shall have provided Employee with notice setting forth with specificity
(1) the conduct deemed to constitute such "cause," (2) reasonable action, if
any, that would remedy the objectionable conduct, and (3) a reasonable time
within which Employee may take such remedial action (provided, however, that the
Company shall not be required to provide additional time for remedial action in
the event of repeated instances of the conduct deemed to constitute cause for
which it has already given prior notice and time for remedial action in
accordance with the provisions of this Agreement), and (ii) Employee shall not
have taken and accomplished such specified remedial action within such specified
reasonable time. The Company's liability, if any, for payments to Employee by
virtue of any wrongful termination of Employee's employment pursuant to this
Agreement shall be reduced by and to the extent of any earnings received by or
accrued for the benefit of Employee during any unexpired part of the Employment
Term.

     5.4. WITHOUT CAUSE.  The Company shall have the right to terminate the
Employment Term without cause at any time by giving Employee written notice of
such termination.  Under such circumstances the Company shall continue for a
period of ___ (_) months from the effective date of such termination (the
"Severance Period") (a) the Monthly Salary, (b) in accordance with (and to the
extent permitted by) the provisions of the Company's health plans then in
existence and the provisions of the Consolidated Omnibus Reconciliation Act of
1985 ("COBRA") as supplemented or amended, and subject to any deductibles,
limitations, exclusions, and any co-payments and other cost sharing features
thereof, any medical insurance benefits to which Employee was entitled
immediately prior to the receipt of notice of termination (or, at the Company's
option, pay Employee an amount in cash equal, on an after-tax basis, to the
premiums for such coverages), and (c) to continue to vest and permit the
exercise of such stock options as 

                                       8
<PAGE>
 
have been granted to the employee prior to the effective date of such
termination, in accordance with and subject to the provisions of the applicable
stock option plans and the option agreements pursuant to which the options were
granted. The foregoing notwithstanding, (i) any obligation to provide medical
insurance or payment in lieu thereof, shall expire when Employee is employed by
a new employer that provides health insurance to its employees on a comparable
cost-sharing basis to that provided by the Company, and (ii) Employee
acknowledges that as a result of the foregoing, any stock options intended to
qualify as incentive stock options will no longer qualify and accordingly will
be treated as non-qualified stock options. Employee shall only have the right to
receive payment for incentive compensation, if any, referred to in Section 1.5
hereof to which Employee would have been entitled in accordance with and subject
to the provisions of the applicable plans or programs as duly adopted by the
Company. Except as expressly stated in this paragraph, upon the termination of
this Agreement Employee shall not be entitled to any payments or benefits which
may be provided to employees of the Company. Payments and benefits to be
provided hereunder shall in all respects be conditioned upon (1) the prior
receipt by the Company from Employee of a general release of all claims of any
nature whatsoever which Employee had, has or may have against the Company and
related parties relating to Employee's employment by the Company (other than
Employee's entitlement under any employee benefit plan or program sponsored by
the Company in which Employee participated and under which Employee has accrued
a benefit) or the termination thereof, such release and covenant to be in form
and substance reasonably satisfactory to counsel for the Company, and (2)
continued compliance by Employee with the Confidentiality Agreements and, for
the duration of the Severance Period, the Restrictive Covenants.

          5.5  RESIGNATION FOR GOOD REASON.   Employee shall have the right to
terminate the Employment Term at any time for Good Reason, by giving the Company
ninety (90) days' prior written notice of such termination. For purposes of this
Agreement "Good Reason" shall mean, exclusively, a resignation based upon (a) a
failure of the Company to observe or perform any of the material terms or
provisions of this Agreement (including, for example, any reduction in the
Monthly Salary other than a

                                       9
<PAGE>
 
reduction which is a concurrent reduction on a
comparable basis of the other management level employees), or (b) a material
reduction in Employee's level of responsibility, position (including office and
title, but not including reporting relationships), authority or duties
(including changes resulting from the assignment to Employee of any duties and
responsibilities inconsistent with Employee's Position as in effect on the date
of this Agreement), in each case as determined by Employee acting reasonably and
in good faith.  Employee's notice of termination hereunder shall specify the
basis for Employee's determination of "Good Reason"; provided, however, that the
Company's conduct shall not constitute "Good Reason" unless and until (i)
Employee shall have given the Company written notice setting forth with
specificity (1) the conduct deemed to constitute "Good Reason," (2) reasonable
action that would remedy the objectionable conduct, and (3) a reasonable time
within which the Company may take such remedial action, and (ii) the Company
shall not have taken and accomplished such specified remedial action within such
specified reasonable time.  Under such circumstances the Company shall continue
for the Severance Period (as defined in the previous paragraph) (a) the Monthly
Salary, (b) in accordance with (and to the extent permitted by) the provisions
of the Company's health plans then in existence and the provisions of the
Consolidated Omnibus Reconciliation Act of 1985 ("COBRA") as supplemented or
amended, and subject to any deductibles, limitations, exclusions, and any co-
payments and other cost sharing features thereof, any medical insurance benefits
to which Employee was entitled immediately prior to the receipt of notice of
termination (or, at the Company's option, pay Employee an amount in cash equal,
on an after-tax basis, to the premiums for such coverages), and (c) to continue
to vest and permit the exercise of such stock options as have been granted to
the employee prior to the effective date of such termination, in accordance with
and subject to the provisions of the applicable stock option plans and the
option agreements pursuant to which the options were granted.  The foregoing
notwithstanding, (i) any obligation to provide medical insurance or payment in
lieu thereof, shall expire when Employee is employed by a new employer that
provides health insurance to its employees on a comparable cost-sharing basis to
that provided by the Company, and (ii) Employee acknowledges that as a result of
the foregoing, any stock options intended to qualify as incentive stock options
will no longer qualify and 

                                       10
<PAGE>
 
accordingly will be treated as non-qualified stock options. Employee shall only
have the right to receive payment for incentive compensation, if any, referred
to in Section 1.5 hereof to which Employee would have been entitled in
accordance with and subject to the provisions of the applicable plans or
programs as duly adopted by the Company. Except as expressly stated in this
paragraph, upon the termination of this Agreement Employee shall not be entitled
to any payments or benefits which may be provided to employees of the Company.
Payments and benefits to be provided hereunder shall in all respects be
conditioned upon (1) the prior receipt by the Company from Employee of a general
release of all claims of any nature whatsoever which Employee had, has or may
have against the Company and related parties relating to Employee's employment
by the Company (other than Employee's entitlement under any employee benefit
plan or program sponsored by the Company in which Employee participated and
under which Employee has accrued a benefit) or the termination thereof, such
release and covenant to be in form and substance reasonably satisfactory to
counsel for the Company, and (2) continued compliance by Employee with the
Confidentiality Agreements, and, for the duration of the Severance Period, the
Restrictive Covenants.

     6.   COORDINATION OF BENEFITS; NO SET-OFF. Other severance plans generally,
or policies or agreements, if any, applicable to Employee or to employees of the
Company generally, and any other severance payments required by applicable
statutes or provided under government programs, may provide compensation and
benefits to Employee upon events which would also require the Company pursuant
to this Agreement to provide compensation or continue benefits. In such event,
Employee shall be entitled only to the largest cash compensation provided for
under any of such agreements, plans, policies, statutes or programs, including
this Agreement, and the maximum benefit continuance provided for under any of
such agreements, plans, policies, statutes or programs, including this
Agreement.

     7.   CERTAIN REDUCTION OF PAYMENTS.

     (a)  Anything in this Agreement to the contrary notwithstanding, in the
event that it shall be determined as set forth herein that any payment or
distribution by, or benefit 

                                       11
<PAGE>
 
provided by, the Company to or for the benefit of Employee, whether paid or
payable, made available to or distributed or distributable pursuant to the terms
of this Agreement or otherwise (a "Payment"), would constitute an "excess
parachute payment" within the meaning of Section 280G of the Internal Revenue
Code of 1986, as amended (the "Code"), and that it would be economically
advantageous to the Company to reduce the Payment to avoid the limitation of the
Company's deduction for such excess parachute payments under Section 280G of the
Code, the aggregate present value of amounts payable or distributable to or for
the benefit of Employee pursuant to this Agreement (such payments, benefits or
distributions pursuant to this Agreement are hereinafter referred to as
"Agreement Payments") shall be reduced (but not below zero) to the Reduced
Amount. The "Reduced Amount" shall be an amount expressed in present value which
maximizes the aggregate present value of Agreement Payments without causing any
Payment not to be deductible by the Company under Section 280G of the Code. For
purposes of this Section 7, present value shall be determined in accordance with
Section 280G(d)(4) of the Code.

     (b)  All determinations to be made under this Section 7 shall be made by
the Company's firm of independent public accountants (the "Accounting Firm"),
which firm shall use its best efforts to provide its determinations and any
supporting calculations both to the Company and Employee within fifteen (15)
days of any termination for which payment under Section 5 is required hereunder.
Any such determination by the Accounting Firm shall be final and binding upon
the Company and Employee. Employee shall in Employee's sole discretion determine
which and how much of the Agreement Payments shall be eliminated or reduced
consistent with the requirements of this Section 7. Within ten (10) days after
the Company's determination, the Company shall pay (or cause to be paid) or
distribute (or cause to be distributed) to or for the benefit of Employee such
amounts as are then due to Employee under this Agreement.

     (c)  As a result of the uncertainty in the application of Section 280G of
the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Agreement Payments, as the case may be, will have
been made by the Company 

                                       12
<PAGE>
 
which should not have been made ("Overpayment") or that additional Agreement
Payments which have not been made by the Company could have been made
("Underpayment"), in each case, consistent with the calculations required to be
made hereunder. Within two years after the applicable termination of employment,
the Accounting Firm shall review the determination made by it pursuant to the
preceding paragraph. In the event that the Accounting Firm determines that an
Overpayment has been made, any such Overpayment shall be treated for all
purposes as a loan to Employee which Employee shall repay to the Company
together with interest at the applicable Federal rate provided for in Section
7872(f)(2) of the Code (the "Federal Rate"); provided, however, that no amount
shall be payable by Employee to the Company if and to the extent such payment
would not affect the limitations on the amount which is not deductible under
Section 280G of the Code. In the event that the Accounting Firm determines that
an Underpayment has occurred, any such Underpayment shall be promptly paid by
the Company to or for the benefit of Employee together with interest at the
Federal Rate.

     (d)  All of the fees and expenses of the Accounting Firm in performing the
determinations referred to in subsections (b) and (c) above shall be borne
solely by the Company.  The Company agrees to indemnify and hold harmless the
Accounting Firm of and from any and all claims, damages and expenses of any
nature resulting from or relating to its determinations pursuant to subsections
(b) and (c) above, except for claims, damages or expenses resulting from the
gross negligence or willful misconduct of the Accounting Firm.

     8.   SURVIVAL.  Notwithstanding expiration or termination of the Employment
Term and except as is expressly set forth herein, Employee's obligations under
the Confidentiality Agreements and Restrictive Covenants shall survive and
remain in full force and effect for the periods therein provided, and Employee's
agreements, covenants and representations under Sections 1.2(b) and 3 of this
Agreement, the provisions for arbitration and equitable relief under Section 4
of this Agreement, the provisions for certain payments after the Employment Term
in Sections 5, 6 and 7 of this Agreement, 

                                       13
<PAGE>

     11.  CONTENTS OF AGREEMENT; AMENDMENT AND ASSIGNMENT.

     (a)  This Agreement (including the Restrictive Covenants) and the
Confidentiality Agreements supersede all prior agreements and set forth the
entire understanding among the parties hereto with respect to the subject matter
hereof or thereof and cannot be changed, modified, extended or terminated except
upon written amendment approved by the parties and executed on their behalf by a
duly authorized officer in the case of the Company and Employee in the case of
Employee.  Without limitation of the foregoing, Employee acknowledges that the
effect of this provision is that no oral modifications of any nature whatsoever
to this Agreement or the Confidentiality Agreements shall be permitted.  In
addition, nothing in this Agreement or in the Confidentiality Agreements shall
be construed as giving Employee any right to be retained in the employ of the
Company beyond the expiration of the Employment Term, and Employee specifically
acknowledges that if Employee's employment by the Company continues beyond the
expiration of the Employment Term, Employee shall be an employee-at-will of the
Company, and thus subject to discharge at any time by the Company with or
without cause and without compensation of any nature hereunder.

     (b)  Employee acknowledges that from time to time, the Company may
establish, maintain and distribute employee manuals or handbooks or personnel
policy manuals, and officers or other representatives of the Company may make
written or oral statements relating to personnel policies and procedures.  Such
manuals, handbooks and statements are intended only for general guidance.  No
policies, procedures or statements of any nature by or on behalf of the Company
(whether written or oral, and whether or not contained in any employee manual or
handbook or personnel policy manual), and no acts or practices of any nature,
shall be construed to modify this Agreement or the Confidentiality Agreements or
to create express or implied obligations of any nature to Employee.

     (c)  All of the terms and provisions of this Agreement shall be binding
upon and inure to the benefit of and be enforceable by the respective heirs,
executors, administrators, legal representatives, successors and assigns of the
parties hereto, except that the duties and responsibilities of Employee
hereunder are of a personal nature and shall not be assignable or delegatable in
whole or in part by Employee.

     12.  SEVERABILITY.  If any provision of this Agreement or application
thereof to anyone or under any circumstances is held to be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect any other provision or application of this Agreement which can be given
effect without the invalid or unenforceable provision or application and shall
not invalidate or render unenforceable such provision or application in any
other jurisdiction.

     13.  REMEDIES CUMULATIVE; NO WAIVER. No remedy conferred upon the Company
by this Agreement is intended to be exclusive of any other remedy, and each and
every such remedy shall be cumulative and shall be in addition to any other
remedy given hereunder or now or hereafter existing at law or in equity. No
delay or omission by the Company in exercising any right, remedy or power
hereunder, under the Confidentiality Agreements, or existing at law or in equity
shall be construed as a waiver thereof, and any such right, remedy or power may
be exercised by the Company from time to time and as often as may be deemed
expedient or necessary by the Company in it sole discretion.

     14.  MISCELLANEOUS.  All section headings are for convenience only.  This
Agreement may be executed in several counterparts, each of which is an original.
It shall not be necessary in marking proof of this Agreement or any counterpart
hereof to produce or account for any of the other counterparts.

                            STOCK OPTION GRANT FOR

                  HENRY I. BOREEN AS CHIEF EXECUTIVE OFFICER

1.   PURPOSE.  The purpose of this grant is to provide compensation for
     -------                                                           
     Henry I. Boreen for his services as Chief Executive Officer ("CEO") as
     adopted and approved by the Board of Directors (the "Board") of Integrated
     Circuit Systems, Inc. (the "Company") on September 11, 1998.

2.   GRANT.  As approved by the Board, Mr. Boreen will be granted an option to
     -----                                                                    
     purchase 30,000 shares of the Company's Common Stock, under the Company's
     1997 Equity Compensation Plan, at the closing price as reported on the
     NASDAQ interdealer quotation system on September 11, 1998, the date of this
     grant. Such grant is not intended to qualify as an incentive stock option
     under Section 422 of the Internal Revenue Code.

3.   VESTING.  Such option shall vest immediately upon the execution of this
     -------                                                                
     grant by the Company and Mr. Boreen.

4.   EXERCISE OF OPTIONS.  The period during which options shall be exercisable
     -------------------                                                       
     shall be five years after the date of grant. Subject to the foregoing,
     options shall be exercisable at such times and be subject to such
     restrictions and conditions as the Board shall in each instance determine,
     which restrictions and conditions need not be the same for all options.

5.   PAYMENT OF OPTION PRICE.  No shares of Common Stock shall be issued upon
     -----------------------                                                 
     exercise of an option until full payment of the option price therefor has
     been made. To the extent permitted by the Board, payment of the option
     price may be made: (i) in cash; (ii) by exchange of Common Stock valued at
     its fair market value on the date of exercise; (iii) by requesting that the
     Company withhold from the number of shares of Common Stock otherwise
     issuable upon exercise of the option that number of shares of Common Stock
     having an aggregate fair market value on the date of exercise (the
     difference between the exercise price and the fair market value on the date
     of exercise) equal to the exercise price for all of the shares of Common
     Stock as to which the option is being exercised; (iv) by means of a
     brokers' cashless exercise procedure; or (v) by any combination of the
     foregoing. Where payment of the option price is to be made with shares of
     Common Stock acquired under any compensation plan of the Company, such
     shares will not be accepted as payment unless the optionee has acquired
     such shares at least six months prior to such payment.

6.   RIGHTS OF SHAREHOLDERS.  Neither an optionee nor his or her legal
     ----------------------                                           
     representatives or beneficiaries shall have any of the rights of a
     shareholder with respect to any shares subject to any option until such
     shares shall have been issued upon the proper exercise of such option.

7.   NON-TRANSFERABILITY OF OPTIONS.  No option may be sold, transferred,
     ------------------------------                                      
     pledged, assigned or otherwise alienated or hypothecated otherwise than by
     will or by the laws of descent and distribution or, with respect to non-
     qualified stock options, pursuant to a qualified domestic relations order
     as defined by the Code, or Title I of the Employee Retirement Income
     Security Act, or the rules thereunder. Except as otherwise specifically
     provided 

                                       19
<PAGE>
 
     herein, all Options granted to an Optionee under the Plan shall be
     exercised during the lifetime of such Optionee only by such Optionee. When
     an optionee dies, the personal representative or other person entitled to
     succeed to the rights of the optionee (the "Successor Optionee") may
     exercise such rights, subject to furnishing to the Company proof
     satisfactory to the Company of his or her right to receive the option under
     optionee's will or under the applicable laws of descent and distribution.

8.   TERMINATION OF EMPLOYMENT OR SERVICE OF OPTIONEE.  Subject to the condition
     ------------------------------------------------                           
     that no option shall be exercisable after the expiration of the period
     fixed by the Board in accordance with Section 4 hereof:

          8.1  In the event that Mr. Boreen ceases to be an employee or director
               of the Company or its subsidiaries by reason of a discharge for
               cause or a voluntary separation of the optionee from the Company
               without the consent of the Company or its subsidiary, the options
               granted to such optionee under the Plan shall terminate
               immediately, unless the Board shall otherwise determine.

          8.2  In the event that the optionee shall die while employed by the
               Company or while serving as a director or within three months
               after (i) termination of employment or service due to disability
               or (ii) retirement of an optionee who is an employee on the
               employee's Retirement Date, any option granted to such optionee
               under the Plan shall be exercisable to the extent then
               exercisable or on such accelerated basis as the Board may
               determine, by his successor in interest, within one year after
               the death of the optionee, unless the Board shall otherwise
               determine.

          8.3  In the event that the employment or service of the optionee
               terminates due to disability (within the meaning of Code Section
               422(e)(3)) and, with respect to an employee, retirement on the
               employee's Retirement Date (as hereinafter defined), any option
               granted to such optionee under the Plan shall be exercisable to
               the extent then exercisable or on such accelerated basis as the
               Board may determine, within a period of three months after such
               termination, unless the Board shall otherwise determine.

          8.4  For purposes of this Paragraph 8, "Retirement Date" shall mean
               any date an employee is otherwise entitled to retire under the
               Company's retirement plans and shall include normal retirement at
               age 65, early retirement at age 62, and retirement at age 60
               after 30 years of service.

9.   RIGHTS OF EMPLOYEES.  Nothing in the Plan shall interfere with or limit in
     -------------------                                                       
     any way the right of the Company or any subsidiary to terminate any
     employee's employment or service for the Company at any time, nor confer
     upon any optionee any right to continue in the employ of the Company or any
     subsidiary. No optionee shall have the right to be selected as an optionee,
     or having been so selected, to be selected again as an optionee.

10.  ADJUSTMENTS IN SHARES SUBJECT TO PLAN.  If the Company shall at any time
     -------------------------------------                                   
     change the number of issued shares of Common Stock without new
     consideration to the Company (such as a stock dividend or stock split), the
     total number of shares available under the Plan, hereof, and the number and
     price of shares of Common Stock subject to outstanding 

                                       20
<PAGE>
 
     options, shall be adjusted so that the aggregate consideration payable to
     the company and the value of each option shall not be changed. If, during
     the term of any option granted under this Plan, the Common Stock shall be
     changed into another kind of stock or into securities of another
     corporation, whether as a result of a reorganization, recapitalization,
     sale, merger, consolidation, or other similar transaction, or if additional
     rights shall be offered with respect to the Common Stock, the Board shall
     cause adequate provision to be made so that the optionees shall thereafter
     be entitled to receive, upon the due exercise or any outstanding options,
     the securities or right that the optionees would have been entitled to
     receive had they owned the Common Stock acquired on the exercise of such
     options on the effective date of any such transaction.

11.  ADDITIONAL RESTRICTIONS.  All options shall be subject to and shall contain
     -----------------------                                                    
     such provisions, limitations and restrictions as may be required on the
     date of grant to permit the grant of the options to comply with or qualify
     for the exemptions with respect to grants of options and stock provided by
     regulations under Section 16 of the Exchange Act and other applicable
     provisions of federal and state securities laws, and to satisfy the
     requirements of other applicable regulatory authorities.

12.  COMPLIANCE WITH RULE 16B-3.  With respect to persons subject to Section 16
     --------------------------                                                
     of the Exchange Act, transactions under this Plan are intended to comply
     with all applicable conditions of Rule 16b-3 or its successors under the
     Exchange Act. To the extent any provision of the plan or action by the
     Board fails to so comply, it shall be deemed null and void, to the extent
     permitted by law and deemed advisable by the Board.

13.  SUBSTITUTION OF OPTIONS IN A MERGER, CONSOLIDATION OR SHARE EXCHANGE.
     --------------------------------------------------------------------  
     In the event that the Company becomes a party to a merger, consolidation or
     share exchange (a "Business Combination") and in connection therewith
     substitutes options under the Plan for options of another party to such
     Business Combination, notwithstanding the provisions of the Plan, the terms
     of such substituted options may have the same terms and conditions
     (provided that the number of shares issuable and the exercise prices are
     adjusted in accordance with the terms of the Business Combination) as the
     former options of such other part to the Business Combination, provided,
     however, that the exercise price of the options to be granted under the
     Plan shall be lawful consideration as determined by the Board.


     IN WITNESS WHEREOF, the Board of Directors has granted this Option as of
the effective date set forth above.
