PART I

ITEM 1. BUSINESS:

COMPANY OVERVIEW

SIPEX Corporation (the "Company" or "SIPEX") designs, manufactures, markets
and sells innovative, high performance, high value-added analog integrated
circuits. The Company sells its products across the analog semiconductor market
and has targeted high-growth sectors that it believes are especially compatible
with its design and process capabilities. Markets for the Company's products are
networking/data communications, consumer electronics, telecommunications,
industrial controls and instrumentation, and aerospace and military. The
Company's products have been incorporated into a broad range of electronic
systems and products by more than 3,500 customers worldwide.

ANALOG INDUSTRY

Integrated circuits, ("IC's"), are the building blocks of all electronic
products today. Analog circuits process "real world" signals which measure
physical conditions such as temperature, force, speed and pressure, the
frequency and wave length of which vary continuously.

The Company believes that the analog/linear integrated circuit market
offers certain advantages compared to the digital market. The life cycles of
products in the analog integrated circuit market tend to be longer and customer
pricing is less volatile than in the digital market. The capital requirements
for analog/linear IC manufacturers are lower than those in the digital IC area.
In addition, foreign competition to date has been less interested in the
analog/linear IC business because the markets are smaller. Unlike products in
the digital IC market, the value in the analog IC product is usually the result
of design innovation utilizing a variety of manufacturing process technologies
to address specific customer applications, many of which are in so-called
"niche" markets.

PRODUCTS AND MARKETS

Requirements for lower power and higher operating frequencies are driving
innovation in analog/linear circuitry. Another significant trend in the
marketplace is the need to reduce the size and weight of components,
particularly for portable and handheld applications in which these features are
critical. As a result, more and more functions are designed onto a single chip,
requiring both advancements in design and improvements in process technology.

The Company offers a broad range of innovative, high performance, high
value-added analog integrated circuits. The Company's products are principally
networking products, electroluminescence products, power management products and
data converter products. In addition, the Company supplies precision high-
reliability assembled products principally to commercial customers supplying
products for aerospace and military applications.

The Company believes that its design and manufacturing process capabilities
can address customers' needs in terms of product features and functionality,
integration and overall solution cost. By working closely and partnering with
established market leaders within these areas, the Company has been able to
identify and meet its partners' complex analog IC requirements with tailored
products that are developed in conjunction with the customer's own product
design team, thus allowing the Company to address the customer's needs as the
customer identifies them. Having addressed the particular needs of market
leaders, the Company is then able to migrate these solutions into standard
products available to other equipment or device suppliers.

THE COMPANY'S MAJOR PRODUCT CATEGORIES

Networking Products. Interface products act as an intermediary to transfer
signals between or within electronic systems. A simple example of an interface
application is a personal computer connected to a printer via the RS-232 serial
interface standard. The computer sends information through the connecting cable
which is received by the printer, and additional information can be sent back to
the computer. Serial interface is used

1
3

in many market segments including computers, peripherals, data communications,
telecommunications, hand-held instrumentation, medical equipment, test equipment
and industrial controls.

In the networking area in particular, serial interface products are of
critical importance because diverse equipment and peripherals must be linked
together to permit data communications across local or remote locations. Because
a multiplicity of communications standards address the diverse requirements of
wide area networking, WAN equipment providers must provide compatibility in
their equipment with different communications standards. WAN equipment OEMs
traditionally addressed this need for systems compatibility through multiple and
often redundant board-level approaches, containing analog circuit designs made
up of many discrete interface drivers and receivers, along with switches,
jumpers or relays to steer the appropriate signals to the connector. The
Company's solution was to develop the first single-chip multi-protocol interface
transceiver circuit. These circuits are programmable and dynamically support
signals compliant with up to eight different serial interface standards. The
Company's products provide network suppliers with the ability to replace
multiple chip and discrete device configurations with a single chip solution,
allowing systems designers to reduce space and power requirements in their
equipment. The Company's SP300 series of interface transceivers each support two
protocols, such as RS-232 and the RS-485, while the Company's SP500 Series was
the industry's first fully integrated transceiver, supporting up to eight of the
most popular serial interface standards for WAN interfaces. As 3V based
microprocessor systems have become more common, SIPEX has introduced families of
3V RS-232 and RS-485. The main product features include fully compliant
operation at 3V power supply with +/-15kV of ESD protection. The products are
mainly sold into battery powered portable products that have a need to interface
to peripheral equipment; including laptop computers, PDAs, and hand held data
terminals.

In addition to expanding its line of programmable serial interface
products, the Company's future interface product strategy includes developing
with industry leaders products involving higher speed interfaces supporting high
speed data communications, video communications and telecommunications interface
requirements. The Company also offers the SP200 and SP400 series of single
protocol serial interface transceiver products, primarily targeted to the
personal computer and peripherals and industrial controls markets.

Electroluminescence and Application Specific Standard Products. The
Company has targeted the battery powered/portable products market to leverage
its design expertise and the process capability provided by the Company's
internal dielectric isolation ("DI") wafer fabrication production line. The DI
process allows single chip designs to operate efficiently with both very low
voltage (1V) and very high voltage (160V) without interference or breakdown
between adjacent circuits. The Company's designers, in cooperation with Timex
Corporation ("Timex"), developed a proprietary electroluminescent ("EL") driver
device, which provides the enabling technology for the Indiglo(R) night-light.
This custom integrated circuit creates a 100V AC signal from a 3V DC battery
within the watch to light the backlight material. Using this technology, the
Company is providing backlighting solutions for pagers, cell-phones and handheld
electronic equipment manufacturers. The Company intends to continue its focus in
this area on high volume commercial/consumer markets, in which the attributes of
the DI fabrication process or the Company's design capabilities can add value
for the customer.

Data Converter Products. Data converter products are incorporated into
systems that translate real world (analog) events into digital data which can be
manipulated by a microprocessor. The Company's analog-to-digital and
digital-to-analog products are components that allow microprocessors to monitor
real world conditions, and then control responses to the conditions monitored.
The main focus of the Company's product offerings has been high performance
12-bit analog-to-digital and digital-to-analog converters. The Company believes
that the data converter marketplace for 12-bit products is highly fragmented,
and design wins are characterized by long life cycles. The primary markets
served by the Company are industrial controls, instrumentation and test
equipment. The Company expects sales of data converter products to decline in
future years as Sipex continues to focus resources on its target markets.

Power Management Products. The Company's power management products
specialize in the areas of voltage control and measurement, voltage conversion
and battery charging. The purpose of these products is to

2
4

monitor the power supplied to digital circuits such as microprocessors and
random access memory ("RAM") in battery operated systems. As the main battery
voltage to the system is slowly decreased by usage, a backup battery takes over
to keep power to the system long enough so that the microprocessor instructions
and RAM are saved and powered down in a safe state. If there is no activity from
the microprocessor during a period of time, the microprocessor is reset so that
it starts-up at a known state in case of errors during power-up, power-down, and
intermittent power losses. Any power glitches or faults that can cause harm to
the system or data loss at any time can be minimized by implementing a
microprocessor supervisory circuit. Any portable equipment that uses
microprocessors, microcontrollers, or memory in the system will require some
kind of detection circuitry to monitor the power supply and battery output.

Aerospace and Assembled Products. The Company's precision high reliability
assembled products are sold to commercial customers engaged in various aerospace
and military programs. The Company is not currently designing new products for
the military market. The Company expects sales of products for military
applications to continue to decline in the future as the Company continues to
focus its resources on its target markets in the commercial sector.

SALES AND DISTRIBUTION

The Company sells its products to OEM customers either directly through its
direct sales force and with the assistance of a network of independent sales
representatives, or indirectly through independent distributors. The Company is
seeking to broaden its customer base by increasing sales through its distributor
network. Domestic and international distributor sales were approximately 46%,
48% and 42% of net sales in 1998, 1997 and 1996 respectively.

The Company's direct sales force consists of sales managers and field
application engineers who provide technical and applications support to
customers, independent sales representatives and distributors. The sales staff
and field application engineers are located at the Company's Billerica,
Massachusetts headquarters and in field sales offices in Munich, Paris, Tokyo,
the United Kingdom and California. The Company's sales staff and field
application engineers also manage, train and support the Company's network of
distributors and representatives.

In North America, Sipex sells its products through 19 independent sales
representative organizations having a total of 40 offices, and 3 distributors
having a total of 140 sales locations. These independent entities are selected
for their ability to provide effective field sales, marketing communications and
technical support to the Company's customers. Sipex has entered into
Representative or Distributor Agreements with each of its independent
distributors and sales representatives. These agreements typically provide for
the independent distributor to act as a non-exclusive distributor for one or
more products within a specific territory and also permit sales representatives
to act as an exclusive or a non-exclusive sales representative in appropriate
circumstances. The Company maintains a separate price list for products sold to
distributors, which typically reflects discounts from the prices charged to
customers in direct sales transactions. Sales representatives directly solicit
orders for the Company's products, which the Company fills directly with the
customer, generating a commission from the Company to the sales representative.
On a semi-annual basis, distributors are permitted to return for credit, against
purchases of an equivalent dollar value of products, up to 10% of their total
purchases during the most recent six-month period.

Outside North America, Sipex sells its products through 33 distributors
having a total of 154 sales locations. International sales in 1998, 1997 and
1996 were approximately $24.0 million, $19.6 million, and $12.1 million,
respectively, representing 36.6%, 38.2%, and 32.5% of net sales, respectively.
In connection with its international sales, the Company is subject to the normal
risks of conducting business internationally, including exchange rate
fluctuations. To date, the Company has not hedged the risks associated with
fluctuations in exchange rates but may undertake such transactions in the
future. The Company currently does not have a policy relating to hedging.

CUSTOMERS

The Company's customer base is comprised of merchant manufacturers,
electronics distributors, and customers with captive manufacturing operations.
The captive manufacturers use the Company's products as integral components in
their equipment and systems. In certain cases, the Company sells its products to
a subcontract-assembly company specified by the captive manufacturer. The
merchant manufacturers typically function as original equipment manufacturers
("OEMs") as well as suppliers of sub-systems to other OEMs.

The Company's customers, none of which accounted for more than ten percent
of net sales in 1998, or 1997, include Cisco Systems, Inc., Hewlett-Packard Co.,
Motorola, Inc., Cabletron Systems, Inc., Lucent Technologies, Inc., Newbridge
Networks Corp., 3Com Corp., and Pairgain Technologies, Inc. in the
networking/data communications markets; Cidco, Inc., Elo Touchsystems, Federal
Express Corp., Timex

4
6

Corporation, International Business Machines Corp., Sharp Corp., Mitsubishi
Corp. and Dassault Aviation S.A. in the consumer and communications markets; and
Andover Controls Corp., Siemens Corporation and Honeywell, Inc. in the
industrial controls market. Customers incorporating the Company's high
reliability assembled products for military applications include Honeywell,
Inc., Raytheon Company and Lockheed Martin Corp.

BACKLOG

The Company's product backlog was approximately $25.6 million at December
31, 1998 compared to $24.8 million in 1997. The Company generally includes in
backlog all orders scheduled for delivery within one year. However, the
Company's business, and to a large extent the entire semiconductor industry, is
characterized by short-term orders and shipment schedules. Sipex generally
permits orders to be canceled or rescheduled without significant penalty to the
customers. As a result, the quantities of the Company's products to be delivered
and their delivery schedules may be revised by customers to reflect changes in
their needs. Since backlog can be canceled or rescheduled, the Company's backlog
at any time is not necessarily indicative of future revenues.

MANUFACTURING

SIPEX manufactures semiconductor wafers for its dielectric isolation
complementary bipolar products in its own facility to optimize the performance
of these products and maintain a high degree of manufacturing control. The
Company's manufacturing facilities in California include a four-inch wafer
fabrication facility and a clean room. The Company's facilities have been
certified as ISO-9001 compliant. In March 1998, the Company entered into an
Operating Lease Agreement for the construction and lease of a 56,000 square foot
wafer fabrication facility and office space in Milpitas, California which is
expected to be completed in the first quarter of 1999. This facility will
provide expanded capacity for the manufacture of wafers and is expected to be
operational in the third quarter of 1999. Although the Company expects the new
fabrication facility to be completed in the first quarter of 1999 and be
operational in the third quarter, there can be no assurance that the Company
will meet this timetable and the Company may experience unexpected delays in
this process.

SIPEX broadens its manufacturing capabilities by using third-party
foundries to produce junction isolation BiCMOS processed wafers and CMOS
processed wafers. The use of third-party foundries enables the Company to focus
on its design strengths and minimize fixed costs and capital expenditures while
providing access to diverse manufacturing technologies without bearing the full
risk of obsolescence. The Company uses three different third-party foundries to
supply fully processed semiconductor wafers for its junction isolation BiCMOS
and CMOS products, all of which foundries have been certified as IS0-9001
compliant. Sales of these products collectively represented approximately 35.6%
in 1998 of the Company's net sales, approximately 38.7% in 1997 and
approximately 41.2% in 1996, and are expected to remain a significant percentage
of net sales in the future. The Company believes it has good long-term
relationships with its third-party foundry suppliers and such relationships are
stable.

The Company tests integrated circuits or "die" on the wafers produced by
the Company and its foundries for compliance with performance specifications
before assembly. The Company's commercial products are assembled by a variety of
subcontractors in Malaysia, Indonesia, Thailand and other locations in Asia, all
of which have been certified as ISO-9002 compliant. Following assembly, the
packaged units are returned to the Company for 100 percent final testing and
inspection prior to shipment to customers. The Company manufactures its
precision high reliability assembled products in Billerica, Massachusetts. The
Company is in conformance with stringent quality and reliability requirements
for military and aerospace applications.

The Company's subcontractors may also be subject to capacity, yield and
quality problems or may have difficulty obtaining critical raw materials, which
could result in disruptions in the supply of assembled products. The Company's
reliance on third-party foundries and independent subcontractors involves a
number of other risks, including reduced control over delivery schedules,
quality assurance and costs. The occurrences of any supply or other problems
resulting from such risks could have a material adverse effect on the Company's
business, financial condition and results of operations.

5
7

From time to time, the overall semiconductor industry has experienced
significant growth, which creates industry-wide capacity shortages and extended
lead times for contract assembly, raw wafers, capital equipment, foundry wafers
and various other products and services that are critical to the Company's
performance. The Company is seeking to establish and maintain critical
inventories and alternate sources to minimize the impact of its vendors'
capacity limitations and to date has not experienced material shortages or
delays. However, there can be no assurance that there will not be future
shortages of key services that will materially and adversely affect the
Company's business, financial condition and results of operations.

The manufacturing processes utilized by the Company are highly complex and
are continuously being modified in an effort to improve yields and product
performance. Process changes can result in interruptions in production or
significantly reduced yields. In addition, yields can be affected by minute
impurities in the environment or other problems that occur in the complex
manufacturing process. Many of these problems are difficult to diagnose and
time-consuming or expensive to remedy. From time to time, the Company has
experienced yield variances. In particular, new process technologies or new
products can be subject to especially wide variations in manufacturing yields
and efficiency. There can be no assurance that yield variances previously
experienced by the Company will not recur or that the Company and its
independent foundries will not experience other manufacturing problems that
result in product introduction or delivery delays. Although previous
fluctuations in yield variances have not materially affected the Company's
business, financial condition or results of operations, there can be no
assurance that future yield variances and resulting delays would not materially
and adversely affect the Company's business and results of operations.

The Company received a Notice of Potential Liability from the Environmental
Protection Agency ("EPA") in June 1993 concerning a landfill identified as a
Superfund Site. The Company has denied any liability and believes the ultimate
outcome of this matter will not have a material impact on the Company.

PRODUCT QUALITY ASSURANCE AND RELIABILITY

The Company is committed to customer satisfaction and continuous
improvement in all aspects its business. This is accomplished through a
comprehensive quality and reliability system founded on documented procedures.
The Company uses quality tools such as statistical process control,
cross-functional teaming, and advanced statistical analysis in its
qualification, production processes, and improvement activities. The Company
maintains strong relationships with its subcontractors and routinely qualifies
suppliers to established standards. The Company is ISO-9001 Registered and has
continuously maintained conformance to MIL-PRF-38534.

PATENTS, LICENSES AND TRADEMARKS

The Company seeks to protect its proprietary technology through patents and
trade secret protection. Currently, Sipex holds a number of patents expiring on
various dates between the years 1999 and 2018 and has additional pending United
States patent applications, although there can be no assurance that any patents
will result from these applications. While the Company intends to continue to
seek patent coverage for its products and manufacturing technology where
appropriate, the Company believes that its success depends more heavily on the
technical expertise and innovative abilities of its personnel than on its patent
position. Accordingly, the Company also relies on trade secrets and confidential
technological know-how in the conduct of its business. There can be no assurance
that the Company's patents or applicable trade secret laws will provide adequate
protection for the Company's technology against competitors who may develop or
patent similar technology or reverse engineer the Company's products. In
addition, the laws of certain territories in which the Company's products are or
may be developed, manufactured or sold, including Asia, Europe and Latin
America, may not protect the Company's products and intellectual property rights
to the same extent as the laws of the United States.

The semiconductor industry is characterized by frequent litigation
regarding patent and other intellectual property rights. Although the Company is
not aware of any pending or threatened patent litigation, there can be no
assurance that third parties will not assert claims against the Company with
respect to existing or future products or technologies and the Company has been
subject to such claims in the past. In the event of litigation to determine the
validity of any third-party claims, such litigation, whether or not determined
in

6
8

favor of the Company, could result in significant expense to the Company and
divert the efforts of the Company's technical and management personnel from
productive tasks. In the event of an adverse ruling in such litigation, the
Company might be required to discontinue the use of certain processes, cease the
manufacture, use and sale of infringing products, expend significant resources
to develop non-infringing technology or obtain licenses to the infringing
technology. There can be no assurance that licenses will be available on
reasonable commercial terms, or at all, with respect to disputed third-party
technology. In the event of a successful claim against the Company and the
Company's failure to develop or license a substitute technology at a reasonable
cost, the Company's business, financial condition and results of operations
would be materially and adversely affected.

Pursuant to license agreements, the Company pays a royalty to Timex
Corporation for certain electroluminescent product sales and to Maxim Integrated
Products for certain interface product sales. The Company continues to receive
royalty payments from Analog Devices Incorporated for certain licensed interface
products.

In October 1998, the Company entered into a royalty bearing license
agreement with the Lemelson Medical, Education and Research Foundation, Limited
Partnership, ("the Lemelson Foundation") by which the Company acquired the right
to use the technology claimed in issued patents and pending patent applications
owned by the Lemelson Foundation. The agreement not only permits the Company to
use the patented technology for the life of the licensed patents but also
provides a covenant not to sue for any use of the patented technology by the
Company which may have occurred before the license agreement was entered into.

RESEARCH AND DEVELOPMENT

SIPEX believes that continued introduction of new products in its target
markets is essential to its growth. As performance demands have increased the
complexity of analog circuits, the design and development process has become a
multi-disciplinary effort, requiring diverse competencies to achieve customers'
desired performance. The Company supports its key designers with an
infrastructure of product and test engineers who perform various support
functions and allow the designer to focus on the core elements of the design.

In 1998, 1997 and 1996, the Company spent approximately $6.7 million, $5.4
million and $4.7 million, respectively, on research and development,
representing, 10.2%, 10.6% and 12.7% respectively, of net sales for such
periods. The Company expects that expenditures in support of research and
development activity will continue to increase in absolute dollars in the near
future.

The Company's ability to compete depends in part upon its continued
introduction of technologically innovative products on a timely basis. The
Company's research and development efforts are directed primarily at designing
and introducing new products and technologies. The Company continually upgrades
its internal technology while also working with foundries to develop new
technologies for new generations of products. In addition, the Company
continually refines its manufacturing practices and technology to improve yields
of its products.

COMPETITION

The Company competes in the high performance segment of the analog
integrated circuit market. The analog integrated circuit segment of the
semiconductor industry is intensely competitive, and many major semiconductor
companies presently compete or could compete in some segment of the Company's
market. The Company's primary competitors have substantially greater financial,
technical, manufacturing, marketing, distribution and other resources and
broader product lines than SIPEX. The Company's current primary competitors in
the high-performance segment of the analog circuit market include Analog
Devices, Inc., Linear Technology Corp. and Maxim Integrated Products, Inc.
Although foreign companies active in the semiconductor market have not
traditionally focused on the high performance analog market, many foreign
companies have the financial and other resources to participate successfully in
these markets, and there can be no assurance that they will not become
formidable competitors in the future.

7
9

The Company believes that its ability to compete successfully depends on a
number of factors, including the ability to develop and introduce new products
rapidly, product innovation, product quality and reliability, product
performance, the breadth of its product line, price, technical service and
support, adequacy of manufacturing quality and capacity and sources of raw
materials, efficiency of production, delivery capabilities and protection of the
Company's products by intellectual property laws. The Company believes that
product innovation, quality, reliability, performance and the ability to
introduce products rapidly are more important competitive factors than price in
its target markets because the Company competes primarily at the stage when
system manufacturers design analog products into their systems. At the design-in
stage, there is less price competition, particularly when there is only one
source for the product. The Company believes that, by virtue of its analog
expertise and rigorous design methodology, it competes favorably in the areas of
rapid product introduction, product innovation, quality, reliability and
performance, but it may be at a disadvantage in comparison to larger companies
with broader product lines, greater technical and financial resources and
greater service and support capabilities.

SEASONAL ASPECTS

None.

ENVIRONMENTAL REGULATION

The Company is subject to a variety of federal, state and local
governmental regulations related to the use, storage, discharge and disposal of
toxic, volatile or otherwise hazardous chemicals used in its manufacturing
process. Although the Company believes that its activities conform to presently
applicable environmental regulations, the failure to comply with present or
future regulations could result in fines being imposed on the Company,
suspension of production or a cessation of operations. Increasing public
attention has been focused on the environmental impact of semiconductor
manufacturing operations, and there can be no assurance that regulatory changes
or changes in regulatory interpretation or enforcement will not render
compliance more difficult and costly. Any failure of the Company to control the
use of, or adequately restrict the discharge of, hazardous substances, or
otherwise comply with environmental regulations, could subject it to significant
future liabilities. In addition, although the Company believes that its past
operations conformed with then applicable environmental laws and regulations,
there can be no assurance that the Company has not in the past violated
applicable laws or regulations, which violations could result in remediation or
other liabilities, or that past use or disposal of environmentally sensitive
materials in conformity with then existing environmental laws and regulations
will not result in remediation or other liabilities under current or future
environmental laws or regulations.

EMPLOYEES

At December 31, 1998, the Company had 299 full-time employees. The Company
believes that its future success will depend, in part, on its ability to attract
and retain qualified technical and manufacturing personnel. This is particularly
important in the areas of product design and development, where competition for
skilled personnel is intense. None of the Company's employees is subject to a
collective bargaining agreement, and the Company has never experienced a work
stoppage. The Company believes that its relations with its employees are good.

===== ===== =====


Fiscal Year Ended December 31, 1998 compared to Fiscal Year Ended December 31,
1997

Net sales increased 28.0% to $65.6 million for the year ended December 31,
1998 compared to $51.2 million for the year ended December 31, 1997. The
increase in net sales was primarily due to higher unit shipments resulting from
continued introductions of new products and increased market acceptance of the
Company's proprietary and second source products. The average selling price for
the Company's products declined slightly during the year. Approximately 37% of
the Company's net sales was derived from international customers in 1998 vs. 38%
in 1997. Geographically, the Company experienced sales growth of 31% in the U.S.
and 23% internationally, primarily in Europe. Sales to Japan and the Rest of the
World, primarily the Pacific Rim countries, increased 8% over the prior year.
International sales were lower as a percentage of net sales in 1998 vs. 1997 due
to prolonged weakness in the Asian markets.

Gross profit was $33.3 million or 50.9% of net sales in 1998 vs. $24.5
million in 1997. The improvements in 1998 over 1997 were primarily due to the
absorption of certain fixed costs over a larger sales base, manufacturing
efficiencies and increased market acceptance of the Company's proprietary and
application specific standard products. This was partially offset by the
slightly lower average selling price for the Company's products.

Research and development ("R&D") expenses were $6.7 million and $5.4
million in 1998 and 1997 or 10.2% and 10.6% of net sales, respectively. The
increase in R&D expense in 1998 as compared to 1997 was due primarily to an
increase in staffing, particularly design engineering personnel and higher
spending for development mask sets and test wafers.

Marketing and selling expenses were $6.6 million and $5.2 million in 1998
and 1997 or 10.0% and 10.2% of net sales, respectively. The increase in
marketing and selling expenses in 1998 over 1997 was due primarily to an
increase in staffing, particularly sales personnel, and an increase in
commission cost associated with sales.

General and administrative expenses were $3.7 million and $3.0 million in
1998 and 1997 or 5.7% and 6.0% of net sales, respectively. The increase in
general administration expense was due primarily to increased legal and other
related professional expenses. The increase is also the result of a write-off of
a customer account receivable.

The facility exit costs of $1.1 million represent the estimated cost of the
closure of the current manufacturing facility in Milpitas, California and the
sales office in France. The charge for property, plant and equipment represents
the write-down to the net realizable value of less efficient and duplicate
machinery and equipment not

12
14

needed in the combined restructured manufacturing operations. Severance and
other employee related costs were included for a reduction of one employee
related to the facility relocation from France to Belgium.

Other income, net was $1.8 million and $1.4 million in 1998 and 1997,
respectively. The year over year increase in other income was due primarily to
higher interest income arising from increases in cash, cash equivalent and
short-term investments which grew $10.1 million and $2.5 million in 1998 and
1997, respectively.

The Company recorded an income tax benefit of ($2.8) million for 1998 and
income tax benefit of ($975,000) for 1997, resulting in an effective income tax
benefit rate of (16.4%) in 1998 compared to an effective rate of (7.9%) in 1997.
These effective rates differed from the statutory rate due to the Company's
utilization of its net operating loss carryforwards which were previously
reserved, and additionally, to the reduction of a portion of the valuation
allowance for future tax benefits expected to be realized in the future. See
also Notes to the Consolidated Financial Statements.

Fiscal Year Ended December 31, 1997 compared to Fiscal Year Ended December 31,
1996

Net sales increased 37.3% to $51.2 million for the year ended December 31,
1997 compared to $37.3 million for the year ended December 31, 1996. The
increase in net sales was primarily due to higher unit sales resulting from
increased market acceptance of the Company's proprietary and application
specific products. Domestic sales increased by 25.7% and international sales
increased by 61.3% in 1997 as compared to the same period in 1996.

Gross profit as a percentage of net sales, or gross margin, increased to
47.9% in 1997 as compared to 42.5% in 1996. The improvements in 1997 over 1996
were primarily due to the absorption of certain fixed costs over the increased
sales volume and due to increased market acceptance of the Company's proprietary
and application specific products.

The Company expended 10.6% of net sales in 1997 for the development and
introduction of new products as compared to 12.7% in 1996. In absolute dollars,
research and development increased 15.3% to $5.4 million in 1997 over the $4.7
million incurred in 1996. The increased spending was due to salary and other
expenses related to the hiring of additional engineering personnel, outside
consulting fees and mask set expenses relating to new product development.

Marketing and selling expenses decreased as a percentage of net sales to
10.2% or $5.2 million in 1997 from 12.1% or $4.6 million in 1996, but increased
14.6% in absolute dollars in 1997 over the same period in 1996. The increase in
1997 was due primarily to higher costs associated with marketing and advertising
of new products and increased commissions.

General and administrative expenses increased to 6.0% of net sales in 1997
from 5.7% in 1996. In absolute dollars, general and administrative expenses
increased to $3.0 million in fiscal 1997 from $2.1 million in 1996. The increase
in 1997 was due primarily to increased travel and professional related expenses.

Other income (expense), net increased to $1,400,000 of income in 1997 from
($53,000) of expense in 1996 primarily as a result of interest income earned on
proceeds of the Company's two public offerings as well as interest earned on
increased cash flow from operations in 1997.

The Company recorded income tax benefit of ($975,000) for 1997 and income
tax expense of $154,000 for 1996 resulting in an effective tax rate of (7.9%) in
1997 compared to an effective tax rate of 3.5% in 1996. These effective rates
differed from the statutory rates due to the Company's utilization of its net
operating loss carryforwards which were previously reserved and additionally in
1997 to the reduction of a portion of the valuation allowance for future tax
benefits expected to be realized in the future. See also Notes to the
Consolidated Financial Statements.

Liquidity and Capital Resources

In April 1996, the Company raised net proceeds of approximately $18.0
million by issuing common stock in its initial public offering. In November
1996, the Company raised net proceeds of approximately
13
15

$33.0 million from the issuance of common stock. The proceeds primarily are used
for capital equipment relating to expansion of facilities and general corporate
purposes including working capital. A portion of the April 1996 proceeds were
applied to pay the $7.5 million in outstanding borrowings to Generale Bank and
$4.8 million of indebtedness to affiliates.

At December 31, 1998, the Company had working capital of $58 million and
available funds of $25.8 million consisting of cash and cash equivalents and
investment securities. The Company has pledged up to $35 million for cash and
cash equivalents and investment securities as security for a lease which the
Company entered into for the construction and lease of a new wafer fabrication
facility in Milpitas, California. The facility is expected to be completed in
the first quarter of 1999. The Company has classified the amount pledged as
retricted long-term assets on the consolidated balance sheet at December 31,
1998. Net cash provided by (used in) operating activities was ($14.6) million,
$8.2 million, and ($60,000) in 1998, 1997 and 1996, respectively. Net cash used
in operating activities in 1998 consisted primarily of $19.8 million of net
income partially offset by a $4.3 million increase in accounts receivable, 2.7
million increase in inventories and $6.9 million increase in deferred taxes, and
a $24.3 million increase in restricted cash associated with the pledge discussed
above. In 1997, net cash provided by operating activities consisted primarily of
$13.2 million of net income partially offset by a $4.3 million increase in
accounts receivable, $2.4 million increase in inventories and $1.3 million
increase in deferred assets. In 1996, the use of cash supported research and
development costs associated with the Company's products and sales and marketing
expenses. Net cash used in 1996 was due primarily to a $4.2 million increase in
inventories and a $1.3 million decrease in accounts payable offset by $4.3
million of net income and $500,000 reduction in accounts receivable.

Net cash used in investing activities for property, plant and equipment was
$4.6 million, $6.5 million and $1.9 million in 1998, 1997 and 1996,
respectively. The growth in 1998 capital investment related to the expansion of
wafer manufacturing in San Jose, California and equipment upgrades in all
facilities.

Net cash provided by financing activities was $5.1 million, $802,000 and
$39.1 million in 1998, 1997 and 1996, respectively. In 1998, $5.1 million was
provided by the issuance of common stock on the exercise of options pursuant to
the Company's stock plans offset partially by the repayments of $45,000 of
capital lease obligations. In 1997, $982,000 was provided by the issuance of
common stock on the exercise of options or pursuant to the Company's stock plans
offset partially by the repayments of approximately $180,000 of capital lease
obligations. In 1996, $51.0 million was provided by the issuance of common stock
in two public offerings offset partially by the repayments of approximately
$12.0 million of long-term debt.

At December 31, 1998, the Company has U.S. net operating loss carryforwards
of approximately $24.4 million, which are available to offset future Federal
taxable income. These losses expire during the years 2005 through 2010. The tax
benefit of utilization of approximately $8.6 million of these net operating loss
carryforwards will result in an increase in additional paid-in capital when
realized. As of December 31, 1998, utilization of these net operating loss
carryforwards is subject to an annual limitation of approximately $7,400,000 as
a result of such an ownership change which occurred on September 30, 1996.

The Company anticipates that the available funds and cash provided from
operations will be sufficient to meet cash and working capital requirements for
the foreseeable future.

New Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") recently issued Statement
of Financial Standards Number 133 ("SFAS 133"), "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments and hedging, requiring
recognition of all derivatives as either assets or liabilities in the statement
of financial position measured at fair value. This statement is effective for
all fiscal quarters of fiscal years beginning after June 15, 1999. The effects
of adopting SFAS 133 is not expected to have a material impact on the Company's
financial condition, results of operations or cash flows.

The AICPA Accounting Standards Executive Committee recently issued
Statement of Position ("SOP") 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use. This statement requires that
certain costs related to the development or purchase of internal-use software be
capitalized and amortized over the estimated useful life of the software, and is
effective for fiscal years

14
16

beginning after December 15, 1998. The statement also requires that costs
related to the preliminary project stage and post implementation/operations
stage in an internal-use computer software development project be expensed as
incurred. The Company will comply with the provisions of SOP 98-1 in fiscal
1999. The adoption of this SOP is not expected to have a material impact on the
Company's financial position or results of operations

The AICPA Accounting Standards Executive Committee recently issued SOP
98-5, Reporting on the Costs of Start-Up Activities. This Statement requires
that costs incurred during start-up activities, including organization costs, be
expensed as incurred, and is effective for fiscal years beginning after December
15, 1998. The Company will comply with the provisions of SOP 98-5 in fiscal
1999. The adoption of this SOP is expected to have no impact on the Company's
financial position or results of operations.

Factors Affecting Future Results

From time to time, information provided by the Company, statements made by
its employees or information included in its filings with the Securities and
Exchange Commission (including in this Form 10-K) may contain statements which
are not historical facts, so called "forward-looking statements", and are made
pursuant to the safe harbor provision of the Private Securities Litigation
Reform Act of 1995 and releases of the Securities and Exchange Commission. In
particular, certain statements contained in the Management's Discussion and
Analysis of Financial Condition and Results of Operations which are not
historical facts (including, but not limited to, statements concerning
anticipated availability of capital for working capital and for capital
expenditures) constitute "forward-looking" statements. The Company's actual
future results may differ significantly from those stated in any forward-looking
statements. Factors that may cause such differences include, but are not limited
to, the factors discussed below and the other risks discussed in the Company's
other filings with the Securities and Exchange Commission.

The Company's quarterly and annual operating results are affected by a wide
variety of factors that could materially and adversely affect net sales and
profitability from period-to-period, including competitive pressures on selling
prices; the timing and cancellation of customer orders; availability of foundry
capacity and raw materials; fluctuations in yields; changes in product mix; the
Company's ability to introduce new products and technologies on a timely basis;
introduction of products and technologies by the Company's competitors; market
acceptance of the Company's and its customers' products; the level of orders
received which can be shipped in a quarter; the timing of investments in
research and development, including tooling expenses associated with product
development, process improvements and production; and the cyclical nature of the
semiconductor industry. Due to the absence of substantial noncancellable
backlog, the Company typically plans its production and inventory levels based
on internal forecasts of customer demand, which are highly unpredictable and can
fluctuate substantially. Because the Company is continuing to increase its
operating expenses for personnel and new product development and for inventory
in anticipation of increasing sales levels, operating results would be adversely
affected if increased sales are not achieved. In addition, the Company is
limited in its ability to reduce costs quickly in response to any revenue
shortfalls. As a result of the foregoing or other factors, the Company may
experience material fluctuations in future operating results on a quarterly or
annual basis which could materially and adversely affect its business, financial
condition and operating results.

Supply and Manufacturing Risks

The Company currently relies on three outside foundries to supply fully
processed semiconductor wafers. There are significant risks associated with
reliance on outside foundries, including the lack of assured wafer supply and
control over delivery schedules, the unavailability of or delays in obtaining
access to key process technologies and limited control over quality assurance,
manufacturing yields and production costs. The Company is also subject to
significant manufacturing risks including yield variances which the Company or
its outside foundries may experience.

15
17

Intellectual Property Rights

The Company relies on certain intellectual property protections to preserve
its intellectual property rights. Any invalidation of these intellectual
property rights or lengthy and expensive defense of these rights could have a
material adverse effect on the Company.

Dependence on New Products

The Company's success will depend upon its ability to develop new
semiconductor devices for existing and new markets, to introduce such products
in a timely manner and to have such products selected for design into new
products of its customers. Successful product development and introduction
depends on a number of factors, including accurate new product definition,
timely completion and introduction of new product designs, availability of
foundry capacity, achievement of manufacturing yields and market acceptance of
the Company's and its customers' products.

Competition; The Semiconductor Industry

The Company competes with several domestic semiconductor companies, most of
which have substantially greater financial, technical, manufacturing, marketing,
distribution and other resources and broader product lines than the Company. The
Company believes that its ability to compete successfully depends on a number of
factors, including the breadth of its product line, the ability to develop and
introduce new products rapidly, product innovation, product quality and
reliability, product performance, price, technical service and support, adequacy
of manufacturing quality and capacity and sources of raw materials, efficiency
of production, delivery capabilities and protection of the Company's products by
intellectual property laws. The semiconductor industry has been highly cyclical
and is subject to significant economic downturns at various times, characterized
by diminished product demand, accelerated erosion of average selling prices and
production over-capacity. The Company may experience substantial
period-to-period fluctuation in future operating results due to general
semiconductor industry conditions and overall economic conditions.

International Sales

The Company derives a significant portion of its net sales from
international sales, including Asia, which are subject to certain risks,
including unexpected changes in legal and regulatory requirements, changes in
tariffs, exchange rates and other barriers, political and economic instability,
difficulties in accounts receivable collection, difficulties in managing
distributors or representatives, difficulties in staffing and managing
international operations, difficulties in protecting the Company's intellectual
property overseas, seasonality of sales and potentially adverse tax
consequences. There can be no assurance that recent economic troubles in certain
Asian countries will not have a material adverse effect on the Company's
business, results of operations and financial condition.

Stock Price Volatility

The trading price of the Company's common stock could be subject to wide
fluctuations in response to quarter-to-quarter variations in operating results,
announcements of technological innovations or new products by the Company or its
competitors, general conditions in the semiconductor manufacturing and
electronic markets, changes in earnings estimates by analysts, or other events
or factors. In addition, the public stock markets have experienced extreme price
and trading volume volatility in recent months. This volatility has
significantly affected the market prices of securities of many technology
companies for reasons frequently unrelated to the operating performance of the
specific companies. These broad market fluctuations may adversely affect the
market price of the Company's common stock.

Year 2000 Readiness Disclosure Statement

The Year 2000 issue results from computer programs written using two digits
rather than four to define the applicable year. Any of the Company's internal
computer programs that have date-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
16
18

miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities.

The Company has assessed its information technology systems and non-IT
systems (such as building security, voice mail, telephone and other systems
containing embedded microprocessors) and has determined the nature and extent of
the work required, if any, to make these internal systems Year 2000 compliant.
In the third quarter of fiscal 1998, the Company selected new enterprise and
manufacturing software systems which are Year 2000 compliant and began
implementation of these systems in the fourth quarter of 1998. Implementation is
scheduled to be fully complete by September 1999. The Company's business is
dependent upon its information systems which are an integral part of all major
business processes. As the Company progresses through the implementation of
these critical operational and logistical modules, there is a risk that these
implementations could be delayed, could experience difficulties or in fact may
not be successful and could adversely affect future results of operations and
cash flows. The Company's current enterprise and manufacturing system is being
upgraded to become Year 2000 compliant in the second quarter of 1999 and will
remain in place until the new system is fully operational. In addition, the
Company's semiconductor manufacturing and payroll systems are being updated and
are expected to be Year 2000 compliant by September 1999. Future expenditures on
the general upgrade of internal computer systems are estimated to be $2 million,
a portion of which would be to become Year 2000 compliant. The majority of these
expenditures will be capitalized in 1999 to the extent in which they relate to
the costs of implementation of new systems. Year 2000 remediation costs will be
expensed as incurred.

The Company has conducted a written survey of its foundries and other
suppliers of products and services with which it has a material relationship in
order to identify and assess their Year 2000 readiness and compliance, and any
negative impacts that any non-compliance could have on the Company. Based upon
the survey responses, the Company found all of these principal suppliers to be
Year 2000 compliant. Although management believes the Company's systems will be
Year 2000 compliant, the failure of the Company's suppliers to address the Year
2000 issue could result in disruption to the Company's operations and have a
significant adverse impact on its results of operations, the extent of which the
Company has not yet estimated. In addition, the Company continues to work with
its customers to identify potential Year 2000 issues with its customers'
products. Many of the Company's key customers are Fortune 500 companies, are
sensitive to Year 2000 issues and are expected to be Year 2000 compliant.
However, the Company continues to survey its customers and monitor their
progress in ensuring Year 2000 compliance. The Company is not actively engaged
in preparing contingency plans in the event that key customers or suppliers fail
to become Year 2000 compliant. However, the Company, in the ordinary course of
business, seeks to expand its customer base to lessen dependence on any one
customer for a significant portion of its revenues, and seeks second sources of
supply for its key products and services where appropriate.

At this time, the Company believes that its most reasonably likely worst
case Year 2000 scenario is that it will be unable to successfully complete the
implementation of its enterprise and manufacturing systems discussed above.
However, the Company has developed contingency plans for this risk and continues
to develop further contingency plans for both mission critical and non-mission
critical systems as it identifies the Year 2000 risks.

Various statements in this discussion of Year 2000 issues are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements include statements of the
Company's expectations, statements with regard to schedules and expected
completion dates and statements regarding expected Year 2000 compliance. These
forward-looking statements are subject to various risk factors which may
materially affect the Company's efforts to achieve Year 2000 compliance. These
risk factors include the inability of the Company to complete the plans and
modifications that it has identified, the wide variety of information systems
and components, both hardware and software, that must be evaluated, the variety,
number and complexity of equipment used in the Company's operations and the
large number of vendors and customers with which the Company interacts. The
Company's assessments of the effects of Year 2000 on the Company are based, in
part, upon information received from third parties and the Company's reasonable
reliance on that information. Therefore, the risk that inaccurate information is
supplied by third parties upon which the Company reasonably relied must be
considered as a risk factor that might affect the

17
19

Company's Year 2000 efforts. The Company is attempting to reduce the risks by
utilizing an organized approach, extensive testing, and allowance of ample
contingency time to address issues identified by tests.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK:

The Company owns financial instruments that are sensitive to market risks
as part of its investment portfolio. The investment portfolio is used to
preserve the Company's capital until it is required to fund operations,
including the Company's research and development activities. None of these
market-risk sensitive instruments are held for trading purposes. The Company
does not own derivative financial instruments in its investment portfolio. The
investment portfolio contains instruments that are subject to the risk of a
decline in interest rates.

Investment Rate Risk -- The Company's investment portfolio includes debt
instruments that are primarily United Stated government bonds of less than one
year in duration. These bonds are subject to interest rate risk, and could
decline in value if interest rates fluctuate. The Company's investment portfolio
also consists of certain commercial paper which is also subject to interest rate
risk. Due to the short duration and conservative nature of these instruments,
the Company does not believe that it has a material exposure to interest rate
risk.

INDEPENDENT AUDITORS' REPORT

The Board Of Directors and Shareholders
SIPEX Corporation

We have audited the accompanying consolidated balance sheets of SIPEX
Corporation (the Company) as of December 31, 1998 and 1997 and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the years in the three year period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of SIPEX
Corporation as of December 31, 1998 and 1997 and the consolidated results of
their operations and their cash flows for each of the years in the three year
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

SIPEX CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1998, 1997, AND 1996

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

SIPEX Corporation (the "Company") designs, manufacturers and markets high
performance and high value added standard analog integrated circuits.
Applications for the Company's products include telecommunications, including
personal computers and peripherals, battery powered handheld devices, cellular
telephones, test equipment, factory automation networking, process controls and
satellites. The Company sells its products across the analog semiconductor
market and has targeted high-growth sectors that it believes are especially
compatible with its design and process capabilities. The Company's product lines
are networking/data communications consumer electronics, industrial controls,
instrumentation, power management and aerospace and military.

Basis of Presentation

The consolidated financial statements include the accounts of SIPEX
Corporation and all of its wholly owned subsidiaries. All intercompany accounts
and transactions have been eliminated.

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Revenue Recognition

Revenue from product sales is recognized at the time of shipment. Revenue
from engineering service contracts is recorded as performance or as other
contractually specified milestones are attained. Additionally, the Company
accrues for estimated sales returns upon shipment.

Cash Equivalents and Short-Term Investments

For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments purchased with an original maturity of 90 days or
less to be cash equivalents. Short-term investments consist of U.S. Government
and municipal bond obligations. The company's investments in debt securities
were classified as held to maturity which means that the Company has the ability
and intent to hold securities until maturity.

Concentration of Credit Risk

Financial instruments of the Company consist of cash, short-term
securities, accounts receivable, accounts payable and capitalized leases. The
carrying amounts of these financial instruments approximate their fair value.

Inventories

Inventories are stated at the lower of cost or market. Costs are determined
using the first-in, first-out method.

SIPEX CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is provided
by using the straight-line method over their useful lives as follows:



USEFUL LIVES
------------

Machinery and Equipment................................. 2-10 years
Furniture, fixtures and office equipment................ 5-10 years
Leasehold improvements.................................. Lease term


Impairment of Long-lived Assets and Long-lived Assets to be Disposed of

The Company reviews long-lived assets and certain identifiable intangibles
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the amount by which the carrying amount of the asset exceed the fair value of
the asset. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less cost to sell.

Foreign Currency Translation

Foreign currency assets and liabilities are translated into dollars at
current rates, and revenues, costs and expenses are translated at average rates
during each reporting period. Gains or losses resulting from foreign currency
transactions are included in earnings currently, while those resulting from
translation of financial statements are shown as a separate component of other
comprehensive income in the statement of shareholders' equity. Such transaction
gains and losses are immaterial for all periods presented.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in earnings in the period that includes the
enactment date.

Net Income Per Share

Basic income per share is based upon the weighted average number of common
shares outstanding. Income per share assuming dilution is based upon the
weighted average number of common and common equivalent shares outstanding
assuming dilution. Dilutive potential common shares outstanding at December 31,
1998, 1997 and 1996 were approximately 1,850,000, 1,700,000 and 1,600,000,
respectively.

2. FACILITY EXIT COSTS

In the fourth quarter of 1998, Management of the Company and the Board of
Directors approved a plan to close its current manufacturing facility in
Milpitas, California and its sales office in France. As part of the plan, the
Company will be vacating the current leased facility in Milpitas and moving
operations to a new facility in Milpitas. Total estimated costs of $938,000
associated with the closure of the facility include $220,000 for rent, real
estate taxes, electricity, heat and water expenses for an estimated six month
period after the building is vacated and until it can be sub-leased or sold. The
balance of $718,000 represents a charge to

current operations for the write-down to net realizable value of less efficient
and duplicate machinery and equipment not needed in the combined restructured
manufacturing operations. Additionally, the Company's plan includes the closure
of its France sales operation and relocation of these activities to the
Company's new site in Belgium. As a result of this action, the Company recorded
$200,000 of facility exit costs related to severance and other related employee
benefit costs. The Company anticipates that substantially all of the facility
exit costs will be paid in 1999.

At December 31, 1998, the Company has U.S. net operating loss carryforwards
of approximately $24.4 million, which are available to offset future Federal
taxable income. These losses expire during the years 2005 through 2010. As of
December 31, 1998, utilization of these net operating loss carryforwards is
subject to an annual limitation of approximately $7,400,000 as a result of such
an ownership change which occurred on September 30, 1996.

The valuation allowance decreased by $9.3 million and $3.6 million during
the years ended December 31, 1998 and 1997, respectively. The Company believes
that it is more likely than not that a portion of the deferred tax assets at
December 31, 1998 will be realized in the future. The valuation allowance as of
December 31, 1998, includes the tax effect of approximately ($3.7) million
attributable to employee stock plans, the benefit of which will be recorded as
increase in paid-in capital when realized. The Company also has tax credit
carryforwards for Federal income tax purposes of approximately $1.5 million
which are available to reduce Federal income taxes. The credits expire during
the years 2001 through 2012.

8. SHAREHOLDERS' EQUITY

Effective April 8, 1996, the number of authorized shares of Common Stock
was increased pursuant to an Amended and Restated Articles of Organization and
the Board of Directors were authorized to issue up to 1,000,000 shares of
preferred stock with terms to be established by the Board at the time of
issuance. In addition, the Company's shareholders' approved a 1-for-4 reverse
split of its issued and outstanding Common Stock. Effective August 18, 1997, the
Company approved a 2 for 1 split of its issued and outstanding common stock. All
shares and per share data presented in the accompanying consolidated financial
statements have been restated to reflect the change in number of authorized and
outstanding shares of Common Stock.

On April 8, 1996 and November 5, 1996, the Company closed the sale, through
an initial and secondary public offering, of 2,160,715 and 1,450,000 shares of
common stock, respectively. The proceeds to the Company from the offerings were
$19.1 million and $33.0 million before deducting expenses from the offerings of
approximately $800,000 and $450,000, respectively.

The Company currently maintains six stock option plans. The 1991
Non-Statutory, 1993 Incentive Stock Option Plan, 1994 Stock Option and Incentive
Plan, 1996 Stock Option Plan, 1996 Non-Employee Director Stock Option Plan and
the 1997 Stock Option Plan have had 744,308, 265,818, 1,187,900, 1,200,000,
300,000 and 1,200,000 shares reserved for issuance, respectively. All plans
allow for options which vest ratably over five years from the date of grant and
expire ten years from the date of grant. Options for 2,024,047 shares are
outstanding as of December 31, 1998 under these plans.

In January 1996, the Board Of Directors approved the 1996 Employee Stock
Purchase Plan, pursuant to which the Company is authorized to issue up to
500,000 shares of common stock to its full-time employees, nearly all of whom
are eligible to participate. Under the terms of the Plan, employees can choose
each year to have up to 10 percent of their annual base earnings withheld to
purchase the Company's common stock. The purchase price of stock is 85 percent
of the lower of its beginning-of-period or end-of-period market price. Under the
Plan, the Company sold 34,359 shares to employees since inception of the plan.

The Company applies APB Opinion 25 and related interpretations in
accounting for these plans. Accordingly, no compensation cost has been
recognized. Had compensation cost been determined pursuant to SFAS No. 123, the
Company's net income and net income per share would have been adjusted to the
pro forma amounts indicated in the table below. The effects on pro forma net
income obtained from applying SFAS No. 123 may not be representative of the
effects on reported net income for future years.

The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in 1998, 1997 and 1996 respectively; no dividend
yield; expected volatility of 77 percent for 1998 and 45 percent for 1997 and
1996, and expected option lives of six years. The risk free interest rate
assumed was 4.95 percent for 1998, 5.65 percent for 1997 and 7.0 percent for
1996. The weighted-average fair value of options granted during 1998, 1997 and
1996 was $16.88, $9.54, and $6.00, respectively.

In March, 1998 the Company entered into a five-year operating lease
agreement, including a one-year construction period, with one five year renewal
option for the construction and lease of a wafer manufacturing facility,
including all necessary machinery and equipment ("the facility"). The total cost
of the facility is

limited to $40,000,000. The lease provides for a substantial residual value
guarantee by the Company at the end of the initial lease term and includes a
purchase option equal to the total cost of the facility. As part of the lease
agreement, the Company has pledged $35 million of government debt securities and
other government backed securities as security under the lease. The lease
provides for monthly lease payments which are estimated to be $170,000. At the
end of the lease term, the Company is obligated to purchase the facility or
remarket it for the benefit of the lessor. The Company expects the fair market
value of the facility, subject to the purchase option or sale to a third party,
to substantially reduce or eliminate the Company's payment under the residual
value guarantee. The residual value guarantee relative to the assets to be
leased will approximate 85% of their total cost.

The Company received a Notice of Potential Liability from the Environmental
Protection Agency ("EPA") in June 1993 concerning a landfill identified as a
Superfund Site. The Company has denied any liability and believes the ultimate
outcome of this matter will not have a material impact on the consolidated
financial statements.

Also, the Company is party to various claims, legal actions and complaints
arising in the ordinary course of business. In the opinion of management, all
such matters are without merit or are of such kind, or involve such amounts,
that unfavorable disposition would not have a material effect on the
consolidated financial position of the Company.
