ITEM 1. BUSINESS

    RadiSys Corporation ("RadiSys" or the "Company"), incorporated in 1987, is a
leader in computer based building blocks used by original equipment
manufacturers ("OEMs") for products in the telecommunications and networked
equipment markets (including industrial automation, medical devices, and
transaction terminals). Unlike general purpose computers, embedded computer
solutions are incorporated into systems and equipment to provide a single or a
limited number of critical system control functions and are generally integrated
into larger automated systems. RadiSys' embedded computers are based upon the
Intel x86, Intel IXP Architecture, and/or the Texas Instruments C6x DSP
architectures and are capable of running PC-compatible operating systems and
application software.

EMBEDDED COMPUTER MARKET

    Embedded computer systems are a key segment of the broad electronics market
and form the backbone and control system for many types of today's electronic
systems requiring advanced capabilities for human interface, data analysis and
system communications and control. Embedded computers differ from
general-purpose computers, such as personal computers (PCs), in several key
respects. First, embedded computers or building blocks, both board level and
chassis systems, are closely integrated into larger systems, perform a single or
limited number of complex applications and adhere to specific requirements
regarding size, reliability and ability to withstand the demands of extreme
environmental conditions. Additionally, embedded computers are design-intensive
solutions that require substantial engineering know-how and a comprehensive
understanding of the specific end product into which they are to be
incorporated.

    Embedded computer solutions are incorporated into a broad range of products,
including voice message systems, local area network routers, cellular base
stations, semiconductor manufacturing equipment, electronics assembly equipment,
blood analyzers, patient monitors, ultrasound machines, gaming equipment, point
of sale terminals and banking automation machines. Unlike PC products, which
have experienced and will likely continue to experience short product cycles, a
typical embedded computer solution has a relatively long product life, with most
designs lasting through the life cycles of the products into which they are
integrated, often three years or more. Life cycles can differ significantly
among industries and applications.

    In recent years, the increasing complexity of electronic subsystems and
components, faster time-to-market requirements, together with a widespread trend
in many industries to rationalize internal manufacturing resources, has led to a
significant growth in the outsourcing of the design and manufacture of
electronics subsystems and components by major OEMs. As a result, the Company
believes there is a significant opportunity for independent manufacturers to
provide OEMs with cost-effective, reliable and high value-added embedded
computer system solutions.

STRATEGY

    The Company's objective is to be the leader in embedded computer solutions
utilizing key technology building blocks for major OEM's in the
telecommunications and networked equipment industry. The key elements of the
Company's highly differentiated strategy are:

    FOCUS ON PROVIDING A WIDE BREADTH OF BEST-IN-CLASS TECHNOLOGY BUILDING
BLOCKS.  There are four key sets of building blocks in a generic
telecommunications system. The first building block is the Central Processing
Unit (CPU), which has been the heritage of RadiSys since incorporation in 1987.
The second building block is DSP (Digital Signal Processing). RadiSys acquired a
DSP company in 1997, Sonitech, which exclusively focuses on providing hardware,
software, and algorithms to support Texas Instruments' C6X DSP architecture. The
third building block is WAN (Wide Area Network) connectivity. RadiSys purchased

                                       3
<PAGE>
a division of International Business Machines Corporation ("IBM") in March of
1999 that enabled the company to garner technology and expertise in T1/E1, X.25,
SS7, ATM, and Frame Relay. The fourth building block is systems packaging and
platform integration. Up until the Company's acquisition of Texas Micro, Inc. in
August of 1999, RadiSys was considered a custom Intel CPU board-level provider
solution. Texas Micro, Inc. brought subsystem integration capabilities, strong
telecommunications customer base and expertise in PCI bus architecture. In
December of 1999, RadiSys augmented the fourth building block by acquiring
another division of IBM called the Open Computing Platform (OCP) division. With
the acquisition of OCP, RadiSys now delivers highly integrated customized
systems with the OEM's logo and when requested, drop ships directly to the OEM's
customer. RadiSys believes that having all four building blocks and the ability
to integrate and test them is a key differentiation between the Company and the
competition in garnering additional design wins and sales, and also gaining
increased opportunities with current and new customers.

    LEVERAGE INTEL ARCHITECTURE EXPERTISE.  RadiSys combines the technical
expertise of hundreds of man-years of Intel architecture experience with a close
working relationship with Intel to design and manufacture innovative Intel-based
building blocks that can be sold individually or bundled into a variety of
levels of integrated solutions for its OEM customers. The Company intends to
continue to capitalize on the growing acceptance of the Intel X86 architecture
and the Intel IXA architecture as the preferred solution of OEMs, especially in
the telecommunications market. Additionally, the Company and Intel's Embedded
Architecture Division are working together to develop and market chip-level,
board-level, and system-level products for the embedded computer market in order
to facilitate the implementation of IA and IXA designs into a broadening array
of new OEM products.

    PROVIDE BROAD SET OF TECHNICAL SOLUTIONS TO MEET CUSTOMER-SPECIFIC
NEEDS.  The Company provides a high degree of design, product, and manufacturing
flexibility to address the needs of its customers for customized solutions in a
wide range of applications. The Company provides building blocks with a variety
of physical form factors and levels of integration, from fully integrated
systems, to application ready platforms, to CPU boards, to chip-level products.
The Company also offers a broad range of custom solutions and maintains a large
and expanding library of designs, containing specifications, logic designs,
firmware, device driver software, test and integration specifications, DSP
algorithms, WAN (Wide Area Network) connectivity, and manufacturing rules. The
Company believes that its extensive design expertise and large library of
solutions is critical to its ability to find the solution that best fits its
customers' technical and business needs.

PRODUCTS

    RadiSys designs and manufactures a broad array of computer-based technology
building blocks based on the Intel architecture--from standard products to
products designed to address the specific requirements of its OEM customers.
These "perfect fit" solutions typically combine the level of integration, degree
of customization and specified form factors and standards required to meet the
customer's needs.

    STANDARD PRODUCTS AND ARCHITECTURES.  RadiSys provides a highly
differentiated set of horizontal and vertical technology building blocks.
RadiSys can deliver Intel CPU platforms, system platforms, wide-area networking
(WAN) and digital signal processing (DSP) technologies on two key architectures,
PCI and CompactPCI. The Company provides state-of-the-art Pentium, PII, PIII,
IXP and StrongArm Solutions. The Company provides both enterprise and carrier
class CompactPCI and PCI system enclosures and backplanes. In addition, the
Company has expertise in field-proven frame relay, SS7, ATM, E1/T1, X.25, IP and
other protocols and interfaces. The Company provides advanced Texas Instrument
(TI) C6x voice processing solutions hardware and algorithms.

    TESTING AND INTEGRATION.  The level of integration required by some OEMs in
the telecom industry has provided an opportunity for RadiSys to deliver its
broad range of solutions. RadiSys has the ability to test and integrate all of
its building blocks with other third party cards and software to provide a fully

                                       4
<PAGE>
integrated system to the specifications of the OEM. This allows OEMs to source
all of these functions to RadiSys so they may focus on the key differentiation
they deliver to their marketplace. Fully integrated computer subsystems and
systems generally range in price from $1,000 to $15,000.

    CUSTOMIZATION.  The degree of customization of the Company's products ranges
from modifications of standard products to custom solutions comprised solely of
newly developed modules. The Company uses its extensive design experience and
large design library to create products with varying degrees of customization.
The Company believes that the degree of customization will tend to increase in
the future and provide a time-to-market advantage for our customers.

SALES AND MARKETING

    RadiSys views the design process as an opportunity to build long-term OEM
customer relationships. The Company typically experiences long life cycles for
products designed for its OEM customers. RadiSys' objective of providing
embedded computer solutions utilizing key technology building blocks focuses the
Company's direct sales force on solving the OEM customer's needs. A typical
sales team consists of an account manager along with supporting engineering
expertise interacting with the OEM customer's technical staff to solve specific
requirements of application; form, fit and function; environment and mechanics.
The Company's value proposition to the customer is a faster time-to-market.

    The Company markets its products primarily in North America, Western Europe,
Israel and Japan. In 1999, the Company had no customer whose sales were more
than 10% of total revenues; the top 25 customers accounted for approximately 65%
of 1999 sales. In North America, products are sold principally through a direct
sales force. The Company has U.S. sales offices in Oregon, Texas, California,
North Carolina, Nevada and Delaware. The direct sales force is supported by
approximately 60 factory-based application engineers, product marketing
personnel and sales support personnel. In addition, the Company's management
plays a key role in the Company's marketing and selling efforts.

    In Europe, the Company sells its products through wholly owned subsidiaries
in the United Kingdom, RadiSys UK Ltd., and RadiSys International, Inc. and
through distributors in Europe. RadiSys has international regional sales offices
in The Netherlands, United Kingdom, Germany, Israel and France. In Japan, the
Company sells its products through a wholly-owned Japanese subsidiary, RadiSys
K.K., that markets the Company's products directly and through several
distributors in Japan. In 1999, 1998 and 1997, international sales represented
approximately 37%, 29% and 30%, respectively, of revenues. Much of the Company's
international sales are denominated in U.S. dollars.

    The Company has established distributor relationships with Arrow/Schweber
Electronics, Pioneer-Standard Electronics, Inc., and Wyle Electronics in North
America and several distributors in Europe to market the Company's chip-level,
board-level and system-level products.

RESEARCH, DEVELOPMENT AND ENGINEERING

    The Company believes its research, development and engineering expertise
represents an important competitive advantage. The Company's research,
development and engineering staff at December 31, 1999 consisted of
approximately 235 engineers and technicians.

    Most of the Company's research, development and engineering efforts are
focused on joint projects with its OEM customers resulting in the development of
custom board-level and system-level products. For these projects, the Company's
engineering staff works closely with the customer and the customers often pay
the Company non-recurring engineering fees as certain milestones are attained.
From time to time, the Company also engages in joint research and development of
other products with certain of its customers and other parties. The Company's
research and development staffs are located in Hillsboro, Oregon; Houston,
Texas; Boca Raton, Florida; Newton, Massachusetts and Birmingham, United
Kingdom.

                                       5
<PAGE>
    In the initial phases of the relationship, considerable attention is given
to the establishment of communications links, such as electronic mail, to enable
the customer's and the Company's sales and engineering staffs to interact on a
real-time or rapid response basis. The Company believes that close and frequent
communication during the design process allows RadiSys to operate as a "virtual
division" within the customer's internal organization. RadiSys' in-depth
understanding of embedded computer technology and applications assists the
customer in resolving its overall product design issues while regular customer
feedback enables RadiSys to increase and continually refresh its understanding
of its customer's specific design requirements.

    The Company typically retains the rights to any technology developed as a
part of the design process. In some cases, the Company agrees to share
technology rights, including manufacturing rights, with the customer, but
generally retains nonexclusive rights to use the technology.

    The embedded computer market is subject to rapid technological development,
product innovation and competitive pressures. Consequently, the Company has
invested and will continue to invest resources in the research and development
of (i) technology building blocks such as embedded modules, platforms, chips and
low-level firmware, (ii) application-specific embedded computers for specific
customers and (iii) design processes and tools. In 1999, 1998 and 1997, the
Company invested $30.5 million, $22.2 million and $19.4 million, respectively,
on research and development.

MANUFACTURING

    The Company currently manufactures the majority of the board-level and
system-level products it sells. Also, due to the addition of ARTIC and OCP from
IBM in 1999, the Company also employs several outside subcontractors to produce
board-level and system-level products including system integration services. The
Company builds its products in highly automated ISO9001 certified manufacturing
plants in Hillsboro, Oregon and Houston, Texas. These plants encompass
surface-mount technology ("SMT") board assembly, test, mechanical assembly and
system assembly and test. ISO9001 certification is the international
designation, developed by the International Organization of Standardization, a
pan-governmental agency, for demonstrating that the Company's systems support
the design and production of products of consistently high quality.

    The Company's Hillsboro, Oregon plant has three automated lines for SMT
board assembly, which are based on equipment purchased primarily from Universal
Instruments. The Company's Houston, Texas plant has two automated lines for SMT
board assembly, which are based on Fuji equipment. The Company estimates that,
as currently configured, the plants have sufficient capacity on multiple-shift
operation to handle planned demand well into 2000. Each line is modular and thus
readily expandable by adding additional inline equipment. The Company plans to
transfer products between the two facilities in 2000 to optimize build and
configuration capability across the Company's products. The Company also has
relationships with outside subcontractors to perform additional production
capabilities.

    Because the products into which embedded computers are integrated typically
have long life cycles, dynamic stress testing of embedded computer products must
be particularly exacting to ensure the reliability of such products. The Company
believes its test processes represent a significant competitive advantage in
this area. The Company uses a variety of commercial and proprietary test
processes including highly accelerated life testing, highly accelerated stress
screening, bed-of-nails, in-circuit and functional test equipment. The highly
accelerated stress screening process detects early lifetime failures by
subjecting products to a series of cycles of rapid temperature change, and
random mechanical vibration while the products are running a self-test program
and are being monitored. The Company has equipment to perform temperature,
humidity, and vibration analysis of products.

    The Company relies on external suppliers for bare printed-circuit board
fabrication, machine-inserted through-hole circuit boards, semiconductor
components, mechanical assemblies, and semiconductor foundry services. Although
many of the raw materials and much of the equipment used in the Company's

                                       6
<PAGE>
manufacturing operation are available from a number of alternate sources,
certain of these components are obtained from a single supplier or a limited
number of suppliers.

    The Company is dependent on third parties for a continuing supply of the
components it uses in the manufacture of its products. For example, the Company
is dependent solely on Intel for the supply of microprocessors and other
components and depends on Toshiba America Inc., Epson Electronic America, Lucent
Technologies and Maxim Integrated Products, Inc. as sole source suppliers for
other components. For some of these components the Company would encounter
difficulty in locating alternative sources of supply.

    The Company relies on a third party foundry to produce its core logic chip
product offerings. There is no assurance that the third party will be willing or
able to supply the Company with sufficient core logic chips to meet its needs in
the future or, if the party were not to meet the Company's needs, that the
Company could obtain satisfactory core logic chips from alternative sources in
sufficient quantities and at acceptable prices.

COMPETITION

    The embedded computer industry is highly competitive and fragmented, and the
Company's competitors differ depending on product type, geographic market and
application type. The Company believes that, from a customer's perspective, the
main competitive factors in the embedded computer industry are time-to-market,
product cost, product quality, breadth of solution, and long-term stability of
both the product and the supplier.

    Because many OEM customers view their embedded computer requirements from a
"make versus buy" perspective, RadiSys often competes against its OEM customers'
ability to design and manufacture satisfactory embedded computer products
in-house. However, the start of the sales cycle begins after the OEM has made a
conscious decision to outsource their building block needs. Establishing a
relationship with a set of key accounts and growing the number of RadiSys design
wins from existing customers, are the pieces of RadiSys' future strategy.

    Off-the-shelf product manufacturers comprise a second set of competitors,
although this product segment is highly fragmented by physical and electrical
form factors. Electronics contract manufacturers form a third set of potential
competitors, although most have no specific product or application design
expertise and simply manufacture to a third party's design.

    Finally, RadiSys competes against companies that provide individual pieces
of embedded system solutions, such as central processing units, digital signal
processors, and wide area networks. The competitors are different depending on
what building blocks are present in the competitive sales cycle. RadiSys
maintains a competitive advantage in being able to provide all four sets of
building blocks in both PCI and Compact PCI architectures.

BACKLOG

    As of December 31, 1999, the Company's backlog was approximately
$59.7 million, as compared to $41.8 million as of December 31, 1998. The Company
includes in its backlog all purchase orders scheduled for delivery within
twelve months, although a majority of the backlog is typically scheduled for
delivery within 90 days.

                                       7
<PAGE>
INTELLECTUAL PROPERTY

    Seventeen U.S. patents have been issued to the Company. The Company has
pending one additional U.S. patent application and one foreign application
covering technology incorporated into its products; however, the Company relies
principally on trade secrets for protection of its intellectual property. The
Company believes, however, that its financial performance will depend much more
on the pace of its product development and its relationships with its customers
than upon such protection. The Company has from time to time been made aware of
others in the industry who assert exclusive rights to certain technologies,
usually in the form of an offer to license certain rights for a fee or
royalties. The Company's policy is to evaluate such claims on a case-by-case
basis. The Company may seek to enter into licensing agreements with companies
having or asserting rights to technologies if the Company concludes that such
licensing arrangements are necessary or desirable.

EMPLOYEES

    As of December 31, 1999, the Company had 1,041 employees, of which 886 were
regular employees and 155 were agency temporary employees or contractors. The
Company is not subject to any collective bargaining agreement, has never been
subject to a work stoppage, and believes that its relations with employees are
good.

ITEM 2. PROPERTIES

    In the U.S. the Company leases the following facilities, (all numbers
approximate): 137,000 square feet of office and manufacturing space in three
buildings in Hillsboro, Oregon; 19,000 square feet of office space in Beaverton,
Oregon; 13,000 square feet of office space in Newton, Massachusetts; 144,000

    The Company has never paid any cash dividends on its Common Stock and does
not expect to declare cash dividends on the Common Stock in the foreseeable
future. The Company's current policy is to retain all of its earnings to finance
future growth.

    As of March 24, 2000, there were approximately 613 holders of record of the
Company's Common Stock. The Company believes that the number of beneficial
owners is substantially greater than the number of record holders because a
large portion of the Company's outstanding Common Stock is held of record in
broker "street names" for the benefit of individual investors.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (IN THOUSANDS)

ACQUISITIONS AND MERGERS

    On December 28, 1999, the Company purchased certain assets of International
Business Machines Corporation's ("IBM") Open Computing Platform (OCP) operation
that focuses on providing highly-customized embedded system solutions to OEM's
primarily in the telecommunications market. The purchase price, including direct
acquisition costs and contingent consideration, was $14.1 million. Pursuant to
the terms of the agreement, the Company may be required to make additional
future payments in March of 2001, 2002, and 2003 based upon a formula tied to
the future OCP revenues. These potential additional future payments will be
accounted for as additional purchase price. The total consideration for the
Acquisition will not exceed $30.0 million. The acquisition was accounted for
using the purchase method. The results of operations for this acquisition have
been included in the financial statements since the date of acquisition.

    On August 13, 1999, the Company completed its merger with Texas Micro, a
formerly publicly-traded embedded computer company headquartered in Houston,
Texas, by issuing approximately 2.8 million shares of the Company's stock for
all the outstanding common stock of Texas Micro. The merger was accounted for as
a pooling-of-interests under Accounting Principles Board Opinion No. 16, and
accordingly, the financial statements have been restated for all periods prior
to the merger to reflect the combined results of operations, financial position
and cash flows. In connection with the merger, the Company recorded a charge to
operating expenses of approximately $6.0 million for merger-related costs in the
third quarter of 1999.

    On March 1, 1999, the Company purchased certain assets of IBM dedicated to
the design, manufacture and sale of IBM's ARTIC communications coprocessor
adapter hardware and software for wide area network and other telephony
applications. The purchase price, including direct acquisition costs, was

                                       12
<PAGE>
$27.5 million. The acquisition was accounted for using the purchase method. The
results of operations for this acquisition have been included in the financial
statements since the date of acquisition.

    On February 18, 1997, the Company purchased substantially all the assets of
Sonitech International, Inc., a provider of digital signal processing hardware
and software solutions for embedded applications. The purchase price included
the issuance of 84 shares of common stock and $1.0 million in cash
consideration. The acquisition was accounted for using the purchase method. The
results of operations for this acquisition have been included in the financial
statements since the date of acquisition.

</TABLE>

YEARS ENDED DECEMBER 31, 1999, 1998, AND 1997

    REVENUES.  Revenues increased 34.6% to $251.1 million for 1999 from $186.5
million for 1998. The increase in revenues in 1999 was due to growth within
existing product lines and movement into higher growth markets, primarily
telecommunications. In addition, the acquisition of ARTIC in March of 1999
resulted in increased revenues and the merger with Texas Micro in August of 1999
enhanced the Company's ability to grow.

    Revenues decreased 2.7% to $186.5 million for 1998 from $191.8 million for
1997. The decrease in revenues in 1998 was primarily caused by customers
reducing orders precipitated by the effects of negative global economic
conditions in the electronics market.

    GROSS MARGIN.  Gross margin increased to 36.8% for 1999 from 33.6% for 1998
primarily as a result of the product mix consisting of a larger portion of
higher margin product relative to lower margin product shipped, which includes
products added as a result of the ARTIC acquisition on March 1, 1999.
Additionally, fixed manufacturing costs were lower relative to higher revenue
levels during 1998. The Company's strategic business model is to price its
products for new design wins at roughly 30-35% gross margins, because the
Company believes this gross margin level represents the best elasticity point to
maximize design wins and thus long term growth and profitability. As such, the
Company expects gross margins to decline gradually over time as new design wins
ramp into production. Typically, products ramp into production 6 to 12 months
after the design win.

                                       13
<PAGE>
    Gross margin decreased to 33.6% for 1998 from 36.8% for 1997 because of an
unfavorable mix of product compared to the prior year. In addition,
manufacturing costs stayed flat despite a drop in production.

    The Company's gross margins are heavily influenced by its OEM sales
relationships. OEM sales are characterized by longer product life cycles and
generally lower gross margins that can vary throughout the product life cycle.
Gross margins are typically lower in the early stages of production for OEM
sales and have the potential to improve over time. The Company establishes gross
margin targets based on the nature of the sales it is pursuing and the desire to
establish new OEM relationships by pricing aggressively to achieve key sales.
However, many of the factors affecting gross margins, such as variances in unit
volumes and timing of orders and component cost, are difficult or impossible to
predict and can cause the Company to be subject to unplanned margin variances.
Gross margins on OEM sales are also particularly sensitive to changes in
customer mix because of both margin variances among individual products and the
relative importance of a single large sale on overall operating results. To
mitigate the effect of short-term margin variances, the Company may employ "step
pricing" techniques in which unit prices decline over the life of the product to
reflect anticipated production efficiencies and/or component cost reductions, or
various "cost sharing" or "cost plus" pricing techniques that serve to reduce
the margin risk to the Company.

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 37.3%
to $30.5 million for 1999 from $22.2 million for 1998, primarily as a result of
increased investment in new product development and costs of enhancements to
existing products. The Company continues to invest in new design wins for OEM
customers and the dollar increases reflect increases in the number of employees
working in research and development including additions resulting from
acquisitions. Research and development expenses as a percentage of total revenue
remained relatively flat from 1998 to 1999.

    Research and development expenses increased 14.7% to $22.2 million for 1998
from $19.4 million for 1997 as a result of investment in new products. Research
and development expenses increased as a percentage of total revenue by 1.8%
primarily as the result of lower revenue levels in 1998.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses, exclusive of goodwill amortization, increased 16.7% to $36.8 million
for 1999 from $31.5 million for 1998. Selling, general and administrative
expenses decreased in 1999 as a percentage of revenues to 14.7%. The dollar
increase of $5.3 million is due to the selling effort to maintain high design
win activity. The 2.2% decrease as a percentage of total revenue is due to
increased efficiencies in managing expenses combined with higher revenue levels,
compared to 1998.

    Selling, general and administrative expense increased 5.3% to $31.5 million
for 1998 from $29.9 million for 1997 primarily as a result of continued focus on
design win success despite a decrease in revenues.

    GOODWILL AND INTANGIBLE AMORTIZATION.  Amortization expense relates to
goodwill and intangibles recorded in connection with the Sonitech acquisition
(Q1 97 - $3.0 million) and the ARTIC acquisition (Q1 99 - $20.6 million).
Amortization periods range from five to fifteen years. Amortization expense
increased by $2.1 million over 1998 primarily as a result of the ARTIC
acquisition. Goodwill recorded for the OCP acquisition in late December 1999,
totals $13.0 million and will be amortized over five years beginning
January 2000.

    COMBINATION COSTS.  Combination costs for the year ended December 31, 1999
resulted from the Texas Micro merger on August 13, 1999. The Company recorded a
charge to operating expenses of approximately $6.0 million for merger-related
costs during the third quarter of 1999. Merger and related costs include
professional and filing fees of $3.3 million, human resource related expenses of
$1.5 million, contract termination costs of $.8 million and other miscellaneous
expenses totaling $.4 million.

                                       14
<PAGE>
    INTEREST INCOME, NET.  Interest income, net decreased 37.8% to $1.2 million
for 1999 from $1.9 million in 1998 due to lower cash and cash equivalents levels
primarily a result of the funding of the ARTIC Business Unit acquisition on
March 1, 1999 and capital expenditures.

    Interest income, net increased 28.8% to $1.9 million for 1998 from
$1.5 million for 1997, due to a higher cash equivalent balance held in 1998.

    OTHER INCOME, NET.  Other income increased by $1.4 million from 1998 due to
the recovery of amounts owed from a prior divestiture with General Automation.
The Company received the final consideration owed in connection with the prior
(1996) sale of Texas Micro's Sequoia Enterprise Systems business unit to General
Automation. Final consideration consisted of $1.5 million in cash, $750 in
notes, and 1,133 shares of General Automation common stock. The receipt of this
consideration resulted in a gain to the Company of $2.2 million in the third
quarter of 1999 and is reflected in other income.

    INCOME TAX PROVISION.  The income tax provision for 1999, 1998 and 1997
reflect effective income tax rates of 3.5%, 28.6% and 37.0%. The decrease in the
effective income tax rates for 1999 is attributed to the Texas Micro net
operating loss carryforwards recognized in the year. The Company has accounted
for certain changes in the federal income tax laws that were effective on June
25, 1999. The tax law change eliminated some restrictions on the utilization of
certain Texas Micro net operating loss carryforwards. Some of the Texas Micro
net operating loss carryforwards are now available to offset RadiSys taxable
income. The adjustment relating to this tax law change resulted in a decrease to
the tax provision for the quarter ended June 30, 1999 and an increase to net
income after tax of $5.2 million. The decrease in the effective tax rate for
1998 compared to 1997 is directly attributable to lower net income.

LIQUIDITY AND CAPITAL RESOURCES

    As of December 31, 1999, the Company had $15.7 million in cash and
equivalents. As of December 31, 1999, the Company had working capital of
approximately $68.9 million. The Company has a $20.0 million line of credit with
a bank which expires September, 2000. As of December 31, 1999, $13.9 million was
outstanding under this arrangement at an interest rate of 8.5%. Amounts
outstanding under the line of credit accrue interest at an annual rate equal to
the lower of the LIBOR plus 1.25% to 2.0% or lender's prime rate (8.5% at
December 31, 1999). There was no balance outstanding as of December 31, 1998.

    Net cash provided by operating activities was $2.1 million, $20.6 million
and $5.5 million for 1999, 1998 and 1997, respectively. The decrease in net cash
provided by operating activities in 1999 was largely attributable to an increase
in accounts receivable over prior years. Cash and cash equivalents decreased
$28.1 million during the year ended December 31, 1999 primarily as a result of
the cash paid and assets purchased for the ARTIC and OCP acquisitions ($41.6
million), increases in accounts receivable ($25.0 million), inventories ($6.6
million), deferred income taxes ($8.1 million), capital expenditures
($8.5 million) and capitalized software production costs and other assets ($3.6
million), and gain on sale of assets ($2.2 million). These cash uses were offset
by cash and cash equivalent increases from short term borrowings ($13.9
million), net income ($19.0 million), depreciation and amortization
($9.6 million), accounts payable ($7.3 million), accrued income taxes
($2.5 million), accrued wages and bonuses ($2.4 million), and other accrued
liabilities ($2.0 million).

    Capital expenditures were $8.5 million, $4.7 million and $4.3 million in
1999, 1998 and 1997, respectively. These capital expenditures were primarily for
the purchase of leasehold improvements, manufacturing equipment, plant
modernization, and the purchase and implementation of SAP financial
applications. Capital expenditures for 2000 are expected to range from
$8.0 million to $10.0 million, resulting in part from the Company's plan to
continue increasing its manufacturing capacities and investments in information
systems.

    The Company believes its existing cash and cash equivalents and cash from
operations will be sufficient to fund its operations for at least the next
12 months. Because the Company's capital requirements cannot be predicted with
certainty, there is no assurance that the Company will not require additional
financing prior to the expiration of 12 months.

YEAR 2000 ISSUES

    The Company recognizes the importance to its operations of Year 2000 issues
and has worked to maintain the availability and integrity of its financial
systems and the reliability of its operational systems. Within the last
three years the Company has evaluated and upgraded or replaced the software
packages underlying the Company's financial systems, major manufacturing
systems, internal and external communication systems, and desktop systems, as
appropriate, to address Year 2000 readiness issues. The Company has also
performed an in-depth analysis of all of its products. In addition, the Company
has been in contact with all major external third party providers to assess
their Year 2000 readiness; this includes third parties who provide financial,
payroll, communications, component, and integration services to the Company.

    The Company has completed its assessment of any Year 2000 difficulties to
date. Any difficulties as a result of Year 2000 have been corrected through
modifications of software and are considered to be insignificant in nature. The
Company has not experienced any significant Year 2000 issues arising from its
third party vendors to date and does not anticipate any such problems arising in
the future. In the event that problems do arise, the Company continues to
maintain a Year 2000 contingency plan.

    The total cost associated with required modifications to become Year 2000
compliant has not been and is not expected to be material to the Company's
results of operations, liquidity and financial condition. The Company estimates
that it has incurred, and will incur, a total of approximately $0.5 million for
its Year 2000 readiness programs. These costs are a portion of ongoing Company
resources and are not separately identifiable.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    INTEREST RATE RISK.  The Company invests its excess cash in debt instruments
of the U.S. Government and its agencies, and in high-quality corporate issuers.
The Company attempts to protect and preserve its invested funds by limiting
default, market and reinvestment risk.

    Investments in both fixed rate and floating rate interest earning
instruments carry a degree of interest rate risk. Fixed rate securities may have
their fair market value adversely impacted due to a rise in interest rates,
while floating rate securities may produce less income than expected if interest
rates fall. Due in part to these factors, the Company's future investment income
may fall short of expectations due to changes in interest rates and the Company
may suffer losses in principal if forced to sell securities which have declined
in market value due to changes in interest rates.

    FOREIGN CURRENCY RISK.  The Company pays the expenses of its international
operations in local currencies. The Company's international operations are
subject to risks typical of an international business, including, but not
limited to: differing economic conditions, changes in political climate,
differing tax structures, other regulations and restrictions, and foreign
exchange rate volatility. Accordingly, the Company's future results could be
materially adversely impacted by changes in these or other factors.

    The Company is also exposed to foreign exchange rate fluctuations as they
relate to operating expenses as the financial results of foreign subsidiaries
are translated into U.S. dollars in consolidation. As exchange rates vary, these
results, when translated, may vary from expectations and adversely impact
overall expected profitability. The effect of foreign exchange rate fluctuations
on the Company in 1999 was not material.

FORWARD-LOOKING STATEMENTS

    Statements and information in this Annual Report on Form 10-K and the
statements the Company's management may make, from time to time, regarding
future industry trends, the Company's expected revenues, earnings and
anticipated gross margins, the Company's future development and introduction of
products, and the Company's future liquidity, development, and business
activities, constitute forward looking statements that involve a number of risks
and uncertainties. The following are among the factors that could cause actual
results to differ materially: business conditions and growth in the
telecommunications and electronics industry and general economy, both domestic
and international; dependence on a limited number of OEM customers; dependence
on the relationship with Intel; lower than expected customer orders or
variations in customer order patterns due to changes in demand for customers'
products and customer and channel inventory levels; competitive factors,
including pricing pressures, technological developments and products offered by
competitors; availability of components and qualified personnel; technological
difficulties and resource constraints encountered in developing new products;
the timely flow of competitive new products and market acceptance of those
products; difficulties in successfully combining the operations of the Company
and Texas Micro. Inc., dependence on a limited number of suppliers; and risks
associated with foreign currency rate fluctuations and other international
operational risks. The forward-looking statements should be considered in light
of these factors. The forward looking statements contained in this Annual Report
on Form 10-K regarding industry trends, product development and introductions,
and liquidity and future business activities should be considered in light of
these factors.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors

and Shareholders of

RadiSys Corporation

    In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of changes in shareholders' equity, and
of cash flows present fairly, in all material respects, the financial position
of RadiSys Corporation and its subsidiaries at December 31, 1999 and 1998, and
the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1999, in conformity with accounting
principles generally accepted in the United States. 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 of these statements in accordance with auditing standards
generally accepted in the United States which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 (IN THOUSANDS)

1. SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION

    RadiSys Corporation (the Company) was incorporated in March 1987 under the
laws of the State of Oregon for the purpose of developing, producing and
marketing computer system (hardware and software) products for embedded computer
applications in manufacturing automation, medical, transportation,
telecommunications and test equipment marketplaces. The accompanying
consolidated financial statements include the accounts of the Company and its
wholly owned subsidiaries. All intercompany accounts and transactions have been
eliminated in consolidation. See Note 11 regarding the merger with Texas Micro
Inc., and the restatement of the Company's financial statements.

    MANAGEMENT ESTIMATES

    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 these estimates. Significant
estimates and judgements made by management of the Company include matters such
as collectibility of accounts receivable, realizability of inventories, rate of
product returns from customers and recoverability of capitalized software and
deferred tax assets.

    RECLASSIFICATIONS

    Certain reclassifications have been made to amounts in prior years to
conform to current year presentation. These changes had no impact on previously
reported results of operations or shareholders' equity.

    CASH AND CASH EQUIVALENTS

    Cash and cash equivalents include short-term investments with original
maturities of less than three months.

    REVENUE RECOGNITION

    The Company generally recognizes revenue from product sales upon shipment.
For sales through distributors, the Company estimates potential returns based
upon contractual limitations and historical return rates and defers revenue
recognition accordingly. The Company may grant certain sales discounts to
distributors. Such sales discounts are reflected as a reduction in the
associated revenue for distributor sales.

    ACCOUNTS RECEIVABLE

    Trade accounts receivable are net of an allowance for doubtful accounts of
$933 and $1,481 at December 31, 1999 and 1998, respectively. The Company's
customers are concentrated in the technology industry. Therefore, the Company's
operations and collection of its accounts receivable are directly associated
with the results of the technology industry.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                                 (IN THOUSANDS)

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INVENTORIES

    Inventories are stated at the lower of cost or market. The Company uses the
first-in, first-out (FIFO) method to determine cost. The Company periodically
evaluates its inventory in terms of obsolete or slow-moving items. Inventories
are net of a reserve for obsolete and slow-moving items of $5,925 and $4,759 at
December 31, 1999, and 1998, respectively.

    LONG-LIVED ASSETS

    The Company accounts for long-lived assets in accordance with Statement of
Financial Accounting Standards No. 121 (SFAS 121), "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,"
which requires the Company to review the impairment of long-lived assets
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable. If this review indicates that the carrying
amounts of long-lived assets will not be recoverable, as determined based on the
estimated undiscounted cash flows of the Company over the remaining amortization
period, the carrying amounts of the long-lived assets are reduced by the
estimated shortfall of cash flows.

    INTANGIBLE ASSETS

    The Company reviews certain identifiable intangible assets for impairment
whenever events or changes in circumstances indicate that the total amount of an
asset may not be recoverable. An impairment loss is recognized when estimated
discounted future cash flows expected to result from use of the asset and its
eventual disposition are less than its carrying amount.

    PROPERTY AND EQUIPMENT

    Property and equipment is recorded at cost and depreciated for financial
reporting purposes using the straight-line basis over estimated useful lives of
three to five years. Equipment under capital leases is amortized using the
straight-line basis over the shorter of the lease term or the economic life of
the underlying asset. Ordinary maintenance and repair expenditures are charged
to expense when incurred. Equipment recorded under capital leases at
December 31, 1999 totaled $1,268 with accumulated amortization of $1,163.

    RESEARCH AND DEVELOPMENT

    Expenditures for research and development are expensed as incurred.

    COMPUTER SOFTWARE PRODUCTION COSTS

    Software production costs incurred subsequent to establishment of
technological feasibility, but before release to customers, are capitalized.
Upon general release of the product, cost capitalization is terminated and the
accumulated costs are amortized based on the greater of the proportion of
current revenues to total revenue estimates for the related product, or
straight-line amortization over the remaining estimated economic life of the
product not to exceed two years. Unamortized software production costs of $4,800
and $3,733 are included in Other assets at December 31, 1999 and 1998,
respectively. Amortization of software production costs in 1999, 1998 and 1997
aggregated $2,193, $1,020 and $722, respectively.

                                 (IN THOUSANDS)

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES

    The Company's general practice is to reinvest the earnings of its foreign
subsidiaries in those operations, unless it would be advantageous to the Company
to repatriate the foreign subsidiaries' retained earnings. Valuation allowances
are established when necessary to reduce deferred tax assets to the amount
expected to "more likely than not" be realized in future tax returns. Tax law
and rate changes are reflected in income in the period such changes are enacted.

    FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES

    The Company estimates the fair value of its monetary assets and liabilities
based upon comparative market values of instruments of a similar nature and
degree of risk. The Company estimates that the carrying amount of all of its
monetary assets and liabilities approximate fair value as of December 31, 1999
and 1998.

    COMPREHENSIVE INCOME

    The Company has adopted Financial Accounting Standards Board (FASB)
Statement No. 130, "Reporting Comprehensive Income" as of January 1, 1998. The
cumulative translation adjustment and unrealized loss on securities available
for sale represent the Company's Other Comprehensive Income items. The
cumulative translation adjustment consists of unrealized gains/losses recorded
in accordance with SFAS No. 52, "Foreign Currency Translation". The Company has
no intention of liquidating the assets of the foreign subsidiaries in the
foreseeable future.

    STOCK-BASED COMPENSATION

    The Company measures compensation expense for its stock-based employee
compensation plans using the intrinsic value method and provides pro forma
disclosures of net income and net earnings per common share as if the fair value
method had been applied in measuring compensation expense. Equity instruments
are not issued to non-employees.

    FOREIGN CURRENCY TRANSLATION

    Assets and liabilities of international operations are translated into U.S.
dollars at current exchange rates. Income and expense accounts are translated
into U.S. dollars at average rates of exchange prevailing during the period.
Adjustments resulting from translating foreign functional currency financial
statements into U.S. dollars are recorded as a separate component of
shareholders' equity. Foreign currency transaction gains and losses are included
in income.

    CASH FLOWS

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    NEW STANDARD

    In 1998, the FASB issued SFAS No. 133 "Accounting for Derivative Instruments
and Hedging Activities" (FAS 133). FAS 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. Management of
the Company anticipates that, due to its limited use of derivative instruments,
the adoption of FAS 133 will not have a significant effect on the Company's
results of operations or its financial position. FAS 137 delayed adoption of FAS
133 to fiscal years commencing after June 30, 2000.

4. GOODWILL AND INTANGIBLE ASSETS

    Goodwill and intangible assets increased by $31.0 million, from
$3.2 million at December 31, 1998 to $34.2 million at December 31, 1999. This
increase is due to goodwill and intangibles recorded from the ARTIC and OCP
acquisitions (see Note 11) of $31.5 million (net of amortization), offset by
$.5 million of increases in other intangibles and amortization from the Sonitech
acquisition and other intangibles. Amortization periods range from five to
fifteen years.

    The Company's net deferred tax asset of $8,916 includes $4,723 classified as
current, with the remaining balance of $4,193 classified non-current. The
non-current portion is included in Other assets on the Consolidated Balance
Sheet and is a result of certain Texas Micro net operating loss carryforwards.
The Company's entire 1998 net deferred tax asset balance of $805 is current.

    The Company accounted for certain changes in the federal income tax laws
that took effect on June 25, 1999. The tax law change made certain Texas Micro
net operating loss carryforwards available to offset RadiSys taxable income.
This portion of the pooling restatement increased net income of the Company by
$5.2 million for the year ended December 31, 1999.

    Options to purchase 269, 1,247, and 321 shares of common stock were
outstanding in 1999, 1998, and 1997, respectively, but were excluded in the
computation of diluted EPS as the options' exercise price was greater than the
average market price of the Company's common stock.

    STOCK OPTION PLAN

    During 1988 and 1995, the Company's shareholders approved stock option
plans. The 1988 plan expired in 1998 and no further shares authorized under that
plan are available for grant. In August, 1999 the Company completed its merger
with Texas Micro and, as a result, options outstanding to existing employees
under Texas Micro's option plans were converted into options to purchase RadiSys
shares, at the effective merger conversion rate of approximately 4.96 shares of
Texas Micro common stock to one share of RadiSys common stock. First time
options granted to new employees generally become exercisable one-third
annually, with no options exercisable in the first year following the grant
date. Options granted to existing employees generally have vesting periods
between two and four years. The difference between the fair market value of the
Company's common stock and the option exercise price at the date of grant, if
material, is recorded as compensation expense ratably over the vesting period of
the related options. Compensation expense related to the stock option plan for
the years ended December 31, 1999,

    EMPLOYEE STOCK PURCHASE PLAN

    In December 1995, the Company established an Employee Stock Purchase Plan
(ESPP). Under the plan, the Company is authorized to sell up to 750 shares of
common stock in a series of eighteen month offerings. Substantially all
employees are eligible to receive rights under the plan. The purchase price is
the lesser of 85% of the fair market value of the common stock on date of grant
or on the purchase date. During 1999 and 1998, the Company issued 95 and 114
shares under the plan, respectively.

    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123 ("FAS 123")

    The Company has elected to account for its stock based compensation under
Accounting Principles Board Opinion No. 25; however, as required by FAS 123 the
Company has computed for pro forma disclosure purposes the value of options
granted during 1999, 1998 and 1997 using the Black-Scholes option pricing model.
The weighted average assumptions used for stock option grants for 1999, 1998 and

                                       30
<PAGE>
8. SHAREHOLDERS' EQUITY (CONTINUED)
1997 were a risk free interest rate of 5.33%, 5.11%, and 5.4%, respectively, an
expected dividend yield of 0%, an expected life of 4 years, and an expected
volatility of 72%, 65%, and 50%, respectively. The weighted average assumptions
used for ESPP rights for 1999, 1998 and 1997 were a risk free interest rate of
5.17%, 5.0% and 5.3%, respectively, an expected dividend yield of 0%, an
expected life of 1.5 years, and an expected volatility of 65%, 62% and 50%,
respectively. The weighted-average fair value of ESPP rights granted in 1999,
1998 and 1997 were $2,060, $1,377, and $656, respectively.

    Options are assumed to be exercised upon vesting for purposes of this
valuation. Adjustments are made for options forfeited prior to vesting. For
the years ended December 31, 1999, 1998 and 1997, the total value of the options
granted was computed to be $19,151, $12,761 and $13,299, respectively, which
would be amortized on a straight line basis over the vesting period of the
options.

    If the Company had accounted for these plans in accordance with FAS 123, the
Company's net income and pro forma net income per share would have been reported
as follows:

    The effects of applying FAS 123 for providing pro forma disclosure for 1999,
1998 and 1997 are not likely to be representative of the effects on reported net
income and earnings per share for future years since options vest over several
years and additional awards are made each year.

11. ACQUISITIONS AND MERGERS

    ARTIC BUSINESS UNIT ACQUISITION

    On March 1, 1999, the Company purchased certain assets of International
Business Machines Corporation ("IBM") dedicated to the design, manufacture and
sale of IBM's ARTIC communications coprocessor adapter hardware and software for
wide area network and other telephony applications ("ARTIC"). The purchase price
aggregated $27.0 million in cash consideration. The acquisition of ARTIC was
accounted for using the purchase method. The results of operations for ARTIC
have been included in the financial statements since the date of acquisition.
The aggregate purchase price of $27.5 million included $.6 million of direct
costs of acquisition and was allocated to fixed assets ($.4 million),
inventories ($6.5 million), patents ($5.0 million) and the remainder to
goodwill.

    OCP BUSINESS UNIT ACQUISITION

    On December 28, 1999, the Company purchased certain assets of IBM's Open
Computing Platform (OCP) operation. OCP develops and sells integrated
computer-based solutions based on Intel architecture, primarily to OEM's of
telecommunications equipment. The purchase price consisted of an aggregate of
$13.9 million in cash consideration. Pursuant to the terms of the agreement, the
Company may be required to make additional future payments in March of 2001,
2002, and 2003 based upon a formula tied to the future OCP revenues. These
potential additional future payments will be accounted for as additional
purchase price. The total consideration for the Acquisition will not exceed
$30.0 million. The acquisition of OCP was accounted for using the purchase
method. The results of operations of OCP have been included in the financial
statements since the date of acquisition. The aggregate purchase price of $14.1
million included $.1 million direct costs of acquisition and $.1 million of
contingent consideration and was allocated to fixed assets ($.2 million),
inventories ($.9 million) and the remainder to goodwill.

    UNAUDITED PRO FORMA DISCLOSURES OF ACQUISITIONS

    The following unaudited pro forma information presents the results of
operations of the Company as if the acquisitions described above had occurred as
of the beginning of 1999 and 1998, after giving effect to adjustments for
amortization of patents and goodwill, estimated reduction of interest income and
the estimated impact on the income tax provision. The unaudited pro forma
financial statements are not necessarily indicative of what actual results would
have been had the ARTIC and OCP acquisitions occurred at the beginning of the
respective periods. The unaudited pro forma information should be read in
conjunction with the Current Report of the Company on Form 8-K dated March 1,
1999 and December 28, 1999 for ARTIC and OCP, respectively, and the Current
Reports of the Company on Form 8-K/A filed April 22, 1999 and March 10, 2000,

11. ACQUISITIONS AND MERGERS (CONTINUED)
    MERGER WITH TEXAS MICRO AND RELATED CHARGES

    On August 13, 1999, the Company completed a merger with Texas Micro Inc.
("Texas Micro"), a formerly publicly-traded embedded computer company
headquartered in Houston, Texas. As a result, the outstanding Texas Micro common
stock was converted into approximately 2.8 million shares of RadiSys common
stock, based on an exchange ratio of approximately 4.96 shares of Texas Micro
common stock for each share of RadiSys common stock. The merger was accounted
for as a pooling-of-interests under Accounting Principles Board Opinion No. 16,
and accordingly, financial statements presented for all periods have been
restated to reflect combined operations and financial position. All intercompany
transactions have been eliminated.

    The following reconciles revenue and net income (loss) previously reported
to the restated information presented in the consolidated financial statements:

                               RADISYS CORPORATION

                            1995 STOCK INCENTIVE PLAN

                     (As Amended Through February 25, 2000)

         1. PURPOSE. The purpose of this Stock Incentive Plan (the "Plan") is
to enable RadiSys Corporation (the "Company") to attract and retain the
services of (1) selected employees, officers and directors of the Company or
of any subsidiary of the Company and (2) selected nonemployee agents,
consultants, advisors, persons involved in the sale or distribution of the
Company's products and independent contractors of the Company or any
subsidiary.

         2. SHARES SUBJECT TO THE PLAN. Subject to adjustment as provided
below and in paragraph 13, the shares to be offered under the Plan shall
consist of Common Stock of the Company, and the total number of shares of
Common Stock that may be issued under the Plan shall not exceed 4,125,000*
shares. The shares issued under the Plan may be authorized and unissued
shares or reacquired shares. If an option, stock appreciation right or
performance unit granted under the Plan expires, terminates or is canceled,
the unissued shares subject to such option, stock appreciation right or
performance unit shall again be available under the Plan. If shares sold or
awarded as a bonus under the Plan are forfeited to the Company or repurchased
by the Company, the number of shares forfeited or repurchased shall again be
available under the Plan.

         3.       EFFECTIVE DATE AND DURATION OF PLAN.

                  (a) EFFECTIVE DATE. The Plan shall become effective as of
August 7, 1995. No option, stock appreciation right or performance unit
granted under the Plan to an officer who is subject to Section 16(b) of the
Securities Exchange Act of 1934, as amended (an "Officer") or a director, and
no incentive stock option, shall become exercisable, however, until the Plan
is approved by the affirmative vote of the holders of a majority of the
shares of Common Stock represented at a shareholders meeting at which a
quorum is present and any such awards under the Plan prior to such approval
shall be conditioned on and subject to such approval. Subject to this
limitation, options, stock appreciation rights and performance units may be
granted and shares may be awarded as bonuses or sold under the Plan at any
time after the effective date and before termination of the Plan.

                  (b) DURATION. The Plan shall continue in effect until all
shares available for issuance under the Plan have been issued and all
restrictions on such shares have lapsed. The Board of Directors may suspend
or terminate the Plan at any time except with respect to

- ------------------
         *        Adjusted to reflect a 3-for-2 stock split of the shares of
                  Common Stock, without par value, of the Company, effected in
                  the form of a 50% share dividend in accordance with ORS
                  60.154, declared by the Board of Directors on October 19,
                  1999, and paid on November 29, 1999 to shareholders of record
                  at the close of business on November 8, 1999.

<PAGE>

options, performance units and shares subject to restrictions then
outstanding under the Plan. Termination shall not affect any outstanding
options, any right of the Company to repurchase shares or the forfeitability
of shares issued under the Plan.

         4.       ADMINISTRATION.

                  (a) BOARD OF DIRECTORS. The Plan shall be administered by
the Board of Directors of the Company, which shall determine and designate
from time to time the individuals to whom awards shall be made, the amount of
the awards and the other terms and conditions of the awards. Subject to the
provisions of the Plan, the Board of Directors may from time to time adopt
and amend rules and regulations relating to administration of the Plan,
advance the lapse of any waiting period, accelerate any exercise date, waive
or modify any restriction applicable to shares (except those restrictions
imposed by law) and make all other determinations in the judgment of the
Board of Directors necessary or desirable for the administration of the Plan.
The interpretation and construction of the provisions of the Plan and related
agreements by the Board of Directors shall be final and conclusive. The Board
of Directors may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any related agreement in the manner and to
the extent it shall deem expedient to carry the Plan into effect, and it
shall be the sole and final judge of such expediency.

                  (b) COMMITTEE. The Board of Directors may delegate to a
committee of the Board of Directors or specified officers of the Company, or
both (the "Committee") any or all authority for administration of the Plan.
If authority is delegated to a Committee, all references to the Board of
Directors in the Plan shall mean and relate to the Committee except (i) as
otherwise provided by the Board of Directors, (ii) that only the Board of
Directors may amend or terminate the Plan as provided in paragraphs 3 and 15
and (iii) that a Committee including officers of the Company shall not be
permitted to grant options to persons who are officers of the Company. If
awards are to be made under the Plan to Officers or directors, authority for
selection of Officers and directors for participation and decisions
concerning the timing, pricing and amount of a grant or award, if not
determined under a formula meeting the requirements of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended, shall be delegated to a
committee consisting of two or more disinterested directors.

         5. TYPES OF AWARDS; ELIGIBILITY. The Board of Directors may, from
time to time, take the following action, separately or in combination, under
the Plan: (i) grant Incentive Stock Options, as defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), as provided in
paragraphs 6(a) and 6(b); (ii) grant options other than Incentive Stock
Options ("Non-Statutory Stock Options") as provided in paragraphs 6(a) and
6(c); (iii) award stock bonuses as provided in paragraph 7; (iv) sell shares
subject to restrictions as provided in paragraph 8; (v) grant stock
appreciation rights as provided in paragraph 9; (vi) grant cash bonus rights
as provided in paragraph 10; (vii) grant performance units as provided in
paragraph 11 and (viii) grant foreign qualified awards as provided in
paragraph 12. Any such awards may be made to employees, including employees
who are officers or

                                       2
<PAGE>

directors, and to other individuals described in paragraph 1 who the Board of
Directors believes have made or will make an important contribution to the
Company or any subsidiary of the Company; provided, however, that only
employees of the Company shall be eligible to receive Incentive Stock Options
under the Plan. The Board of Directors shall select the individuals to whom
awards shall be made and shall specify the action taken with respect to each
individual to whom an award is made. At the discretion of the Board of
Directors, an individual may be given an election to surrender an award in
exchange for the grant of a new award. No employee may be granted options or
stock appreciation rights under the Plan for more than an aggregate of
450,000 shares of Common Stock in connection with the hiring of the employee
or 100,000 shares of Common Stock in any calendar year otherwise.

         6.       OPTION GRANTS.

                  (a)      GENERAL RULES RELATING TO OPTIONS.

                           (i) TERMS OF GRANT. The Board of Directors may grant
         options under the Plan. With respect to each option grant, the Board of
         Directors shall determine the number of shares subject to the option,
         the option price, the period of the option, the time or times at which
         the option may be exercised and whether the option is an Incentive
         Stock Option or a Non-Statutory Stock Option. At the time of the grant
         of an option or at any time thereafter, the Board of Directors may
         provide that an optionee who exercised an option with Common Stock of
         the Company shall automatically receive a new option to purchase
         additional shares equal to the number of shares surrendered and may
         specify the terms and conditions of such new options.

                           (ii) EXERCISE OF OPTIONS. Except as provided in
         paragraph 6(a)(iv) or as determined by the Board of Directors, no
         option granted under the Plan may be exercised unless at the time of
         such exercise the optionee is employed by or in the service of the
         Company or any subsidiary of the Company and shall have been so
         employed or provided such service continuously since the date such
         option was granted. Absence on leave or on account of illness or
         disability under rules established by the Board of Directors shall not,
         however, be deemed an interruption of employment or service for this
         purpose. Unless otherwise determined by the Board of Directors, vesting
         of options shall not continue during an absence on leave (including an
         extended illness) or on account of disability. Except as provided in
         paragraphs 6(a)(iv) and 13, options granted under the Plan may be
         exercised from time to time over the period stated in each option in
         such amounts and at such times as shall be prescribed by the Board of
         Directors, provided that options shall not be exercised for fractional
         shares. Unless otherwise determined by the Board of Directors, if the
         optionee does not exercise an option in any one year with respect to
         the full number of shares to which the optionee is entitled in that
         year, the optionee's rights shall be cumulative and the optionee may
         purchase those shares in any subsequent year during the term of the
         option. Unless otherwise determined by the Board of Directors, if an
         Officer exercises

                                       3
<PAGE>

         an option within six months of the grant of the option, the shares
         acquired upon exercise of the option may not be sold until six months
         after the date of grant of the option.

                           (iii) NONTRANSFERABILITY. Each Incentive Stock Option
         and, unless otherwise determined by the Board of Directors with respect
         to an option granted to a person who is neither an Officer nor a
         director of the Company, each other option granted under the Plan by
         its terms shall be nonassignable and nontransferable by the optionee,
         either voluntarily or by operation of law, except by will or by the
         laws of descent and distribution of the state or country of the
         optionee's domicile at the time of death, and shall be exercisable
         during the optionee's lifetime only by the optionee.

                           (iv)     TERMINATION OF EMPLOYMENT OR SERVICE.

                                    (A) GENERAL RULE. Unless otherwise
                  determined by the Board of Directors, in the event the
                  employment or service of the optionee with the Company or a
                  subsidiary terminates for any reason other than because of
                  physical disability or death as provided in subparagraphs
                  6(a)(iv)(B) and (C), the option may be exercised at any time
                  prior to the expiration date of the option or the expiration
                  of 30 days after the date of such termination, whichever is
                  the shorter period, but only if and to the extent the optionee
                  was entitled to exercise the option at the date of such
                  termination.

                                    (B) TERMINATION BECAUSE OF TOTAL DISABILITY.
                  Unless otherwise determined by the Board of Directors, in the
                  event of the termination of employment or service because of
                  total disability, the option may be exercised at any time
                  prior to the expiration date of the option or the expiration
                  of 12 months after the date of such termination, whichever is
                  the shorter period, but only if and to the extent the optionee
                  was entitled to exercise the option at the date of such
                  termination. The term "total disability" means a medically
                  determinable mental or physical impairment which is expected
                  to result in death or which has lasted or is expected to last
                  for a continuous period of 12 months or more and which causes
                  the optionee to be unable, in the opinion of the Company and
                  two independent physicians, to perform his or her duties as an
                  employee, director, officer or consultant of the Company and
                  to be engaged in any substantial gainful activity. Total
                  disability shall be deemed to have occurred on the first day
                  after the Company and the two independent physicians have
                  furnished their opinion of total disability to the Company.

                                    (C) TERMINATION BECAUSE OF DEATH. Unless
                  otherwise determined by the Board of Directors, in the event
                  of the death of an optionee while employed by or providing
                  service to the Company or a subsidiary, the option may be
                  exercised at any time prior to the expiration date of the
                  option or

                                       4
<PAGE>

                  the expiration of 12 months after the date of death,
                  whichever is the shorter period, but only if and to the extent
                  the optionee was entitled to exercise the option at the date
                  of death and only by the person or persons to whom such
                  optionee's rights under the option shall pass by the
                  optionee's will or by the laws of descent and distribution of
                  the state or country of domicile at the time of death.

                                    (D) AMENDMENT OF EXERCISE PERIOD APPLICABLE
                  TO TERMINATION. The Board of Directors, at the time of grant
                  or, with respect to an option that is not an Incentive Stock
                  Option, at any time thereafter, may extend the 30-day and
                  12-month exercise periods any length of time not longer than
                  the original expiration date of the option, and may increase
                  the portion of an option that is exercisable, subject to such
                  terms and conditions as the Board of Directors may determine.

                                    (E) FAILURE TO EXERCISE OPTION. To the
                  extent that the option of any deceased optionee or of any
                  optionee whose employment or service terminates is not
                  exercised within the applicable period, all further rights to
                  purchase shares pursuant to such option shall cease and
                  terminate.

                           (v) PURCHASE OF SHARES. Unless the Board of Directors
         determines otherwise, shares may be acquired pursuant to an option
         granted under the Plan only upon receipt by the Company of notice in
         writing from the optionee of the optionee's intention to exercise,
         specifying the number of shares as to which the optionee desires to
         exercise the option and the date on which the optionee desires to
         complete the transaction, and if required in order to comply with the
         Securities Act of 1933, as amended, containing a representation that it
         is the optionee's present intention to acquire the shares for
         investment and not with a view to distribution. Unless the Board of
         Directors determines otherwise, on or before the date specified for
         completion of the purchase of shares pursuant to an option, the
         optionee must have paid the Company the full purchase price of such
         shares in cash (including, with the consent of the Board of Directors,
         cash that may be the proceeds of a loan from the Company (provided
         that, with respect to an Incentive Stock Option, such loan is approved
         at the time of option grant)) or, with the consent of the Board of
         Directors (which, in the case of an Incentive Stock Option, shall be
         given only at the time of option grant), in whole or in part, in Common
         Stock of the Company valued at fair market value*, restricted stock,
         performance units or other contingent awards denominated in either
         stock or cash,


- ------------------
         *  The Board of Directors has consented to the use of Common Stock
            in payment of the purchase price, at a fair market value equal to
            the closing price of the Common Stock as reported in THE WALL
            STREET JOURNAL on the last trading day preceding the date the
            option is exercised.


                                       5
<PAGE>

         promissory notes and other forms of consideration. The fair market
         value of Common Stock provided in payment of the purchase price shall
         be determined by the Board of Directors. If the Common Stock of the
         Company is not publicly traded on the date the option is exercised,
         the Board of Directors may consider any valuation methods it deems
         appropriate and may, but is not required to, obtain one or more
         independent appraisals of the Company. If the Common Stock of the
         Company is publicly traded on the date the option is exercised, the
         fair market value of Common Stock provided in payment of the purchase
         price shall be the closing price of the Common Stock as reported in THE
         WALL STREET JOURNAL on the last trading day preceding the date the
         option is exercised, or such other reported value of the Common Stock
         as shall be specified by the Board of Directors. No shares shall be
         issued until full payment for the shares has been made. With the
         consent of the Board of Directors (which, in the case of an Incentive
         Stock Option, shall be given only at the time of option grant), an
         optionee may request the Company to apply automatically the shares to
         be received upon the exercise of a portion of a stock option (even
         though stock certificates have not yet been issued) to satisfy the
         purchase price for additional portions of the option. Each optionee who
         has exercised an option shall immediately upon notification of the
         amount due, if any, pay to the Company in cash amounts necessary to
         satisfy any applicable federal, state and local tax withholding
         requirements. If additional withholding is or becomes required beyond
         any amount deposited before delivery of the certificates, the optionee
         shall pay such amount to the Company on demand. If the optionee fails
         to pay the amount demanded, the Company may withhold that amount from
         other amounts payable by the Company to the optionee, including salary,
         subject to applicable law. With the consent of the Board of Directors
         (which in the case of an Incentive Stock Option, shall be given only at
         the time of option grant), an optionee may satisfy this obligation, in
         whole or in part, by having the Company withhold from the shares to be
         issued upon the exercise that number of shares that would satisfy the
         withholding amount due or by delivering to the Company Common Stock to
         satisfy the withholding amount. Upon the exercise of an option, the
         number of shares reserved for issuance under the Plan shall be reduced
         by the number of shares issued upon exercise of the option.

                  (b) INCENTIVE STOCK OPTIONS. Incentive Stock Options shall be
         subject to the following additional terms and conditions:

                           (i) LIMITATION ON AMOUNT OF GRANTS. No employee may
         be granted Incentive Stock Options under the Plan if the aggregate fair
         market value, on the date of grant, of the Common Stock with respect to
         which Incentive Stock Options are exercisable for the first time by
         that employee during any calendar year under the Plan and under all
         incentive stock option plans (within the meaning of Section 422 of the
         Code) of the Company or any parent or subsidiary of the Company exceeds
         $100,000.

                                       6
<PAGE>

                           (ii) LIMITATIONS ON GRANTS TO 10 PERCENT
         SHAREHOLDERS. An Incentive Stock Option may be granted under the Plan
         to an employee possessing more than 10 percent of the total combined
         voting power of all classes of stock of the Company or of any parent or
         subsidiary of the Company only if the option price is at least 110
         percent of the fair market value, as described in paragraph 6(b)(iv),
         of the Common Stock subject to the option on the date it is granted and
         the option by its terms is not exercisable after the expiration of five
         years from the date it is granted.

                           (iii) DURATION OF OPTIONS. Subject to paragraphs
         6(a)(ii) and 6(b)(ii), Incentive Stock Options granted under the Plan
         shall continue in effect for the period fixed by the Board of
         Directors, except that no Incentive Stock Option shall be exercisable
         after the expiration of 10 years from the date it is granted.

                           (iv) OPTION PRICE. The option price per share shall
         be determined by the Board of Directors at the time of grant. Except as
         provided in paragraph 6(b)(ii), the option price shall not be less than
         100 percent of the fair market value of the Common Stock covered by the
         Incentive Stock Option at the date the option is granted. The fair
         market value shall be determined by the Board of Directors. If the
         Common Stock of the Company is not publicly traded on the date the
         option is granted, the Board of Directors may consider any valuation
         methods it deems appropriate and may, but is not required to, obtain
         one or more independent appraisals of the Company. If the Common Stock
         of the Company is publicly traded on the date the option is exercised,
         the fair market value shall be deemed to be the closing price of the
         Common Stock as reported in THE WALL STREET JOURNAL on the day
         preceding the date the option is granted, or, if there has been no sale
         on that date, on the last preceding date on which a sale occurred or
         such other value of the Common Stock as shall be specified by the Board
         of Directors.

                           (v) LIMITATION ON TIME OF GRANT. No Incentive Stock
         Option shall be granted on or after the tenth anniversary of the
         effective date of the Plan.

                           (vi) CONVERSION OF INCENTIVE STOCK OPTIONS. The Board
         of Directors may at any time without the consent of the optionee
         convert an Incentive Stock Option to a Non-Statutory Stock Option.

                  (c) NON-STATUTORY STOCK OPTIONS. Non-Statutory Stock Options
         shall be subject to the following terms and conditions in addition to
         those set forth in paragraph 6(a) above:

                           (i) OPTION PRICE. The option price for Non-Statutory
         Stock Options shall be determined by the Board of Directors at the time
         of grant and may be any amount determined by the Board of Directors.

                                       7
<PAGE>

                           (ii) DURATION OF OPTIONS. Non-Statutory Stock Options
         granted under the Plan shall continue in effect for the period fixed by
         the Board of Directors.

         7. STOCK BONUSES. The Board of Directors may award shares under the
Plan as stock bonuses. Shares awarded as a bonus shall be subject to the
terms, conditions, and restrictions determined by the Board of Directors. The
restrictions may include restrictions concerning transferability and
forfeiture of the shares awarded, together with such other restrictions as
may be determined by the Board of Directors. If shares are subject to
forfeiture, all dividends or other distributions paid by the Company with
respect to the shares shall be retained by the Company until the shares are
no longer subject to forfeiture, at which time all accumulated amounts shall
be paid to the recipient. The Board of Directors may require the recipient to
sign an agreement as a condition of the award, but may not require the
recipient to pay any monetary consideration other than amounts necessary to
satisfy tax withholding requirements. The agreement may contain any terms,
conditions, restrictions, representations and warranties required by the
Board of Directors. The certificates representing the shares awarded shall
bear any legends required by the Board of Directors. Unless otherwise
determined by the Board of Directors, shares awarded as a stock bonus to an
Officer may not be sold until six months after the date of the award. The
Company may require any recipient of a stock bonus to pay to the Company in
cash upon demand amounts necessary to satisfy any applicable federal, state
or local tax withholding requirements. If the recipient fails to pay the
amount demanded, the Company may withhold that amount from other amounts
payable by the Company to the recipient, including salary or fees for
services, subject to applicable law. With the consent of the Board of
Directors, a recipient may deliver Common Stock to the Company to satisfy
this withholding obligation. Upon the issuance of a stock bonus, the number
of shares reserved for issuance under the Plan shall be reduced by the number
of shares issued.

         8. RESTRICTED STOCK. The Board of Directors may issue shares under
the Plan for such consideration (including promissory notes and services) as
determined by the Board of Directors. Shares issued under the Plan shall be
subject to the terms, conditions and restrictions determined by the Board of
Directors. The restrictions may include restrictions concerning
transferability, repurchase by the Company and forfeiture of the shares
issued, together with such other restrictions as may be determined by the
Board of Directors. If shares are subject to forfeiture or repurchase by the
Company, all dividends or other distributions paid by the Company with
respect to the shares shall be retained by the Company until the shares are
no longer subject to forfeiture or repurchase, at which time all accumulated
amounts shall be paid to the recipient. All Common Stock issued pursuant to
this paragraph 8 shall be subject to a purchase agreement, which shall be
executed by the Company and the prospective recipient of the shares prior to
the delivery of certificates representing such shares to the recipient. The
purchase agreement may contain any terms, conditions, restrictions,
representations and warranties required by the Board of Directors. The
certificates representing the shares shall bear any legends required by the
Board of Directors. Unless otherwise determined by the Board of Directors,
shares issued under this paragraph 8 to an

                                       8
<PAGE>

Officer may not be sold until six months after the shares are issued. The
Company may require any purchaser of restricted stock to pay to the Company
in cash upon demand amounts necessary to satisfy any applicable federal,
state or local tax withholding requirements. If the purchaser fails to pay
the amount demanded, the Company may withhold that amount from other amounts
payable by the Company to the purchaser, including salary, subject to
applicable law. With the consent of the Board of Directors, a purchaser may
deliver Common Stock to the Company to satisfy this withholding obligation.
Upon the issuance of restricted stock, the number of shares reserved for
issuance under the Plan shall be reduced by the number of shares issued.

         9.       STOCK APPRECIATION RIGHTS.

                  (a) GRANT. Stock appreciation rights may be granted under the
Plan by the Board of Directors, subject to such rules, terms, and conditions as
the Board of Directors prescribes.

                  (b)      EXERCISE.

                           (i) Each stock appreciation right shall entitle the
         holder, upon exercise, to receive from the Company in exchange therefor
         an amount equal in value to the excess of the fair market value on the
         date of exercise of one share of Common Stock of the Company over its
         fair market value on the date of grant (or, in the case of a stock
         appreciation right granted in connection with an option, the excess of
         the fair market value of one share of Common Stock of the Company over
         the option price per share under the option to which the stock
         appreciation right relates), multiplied by the number of shares covered
         by the stock appreciation right or the option, or portion thereof, that
         is surrendered. No stock appreciation right shall be exercisable at a
         time that the amount determined under this subparagraph is negative.
         Payment by the Company upon exercise of a stock appreciation right may
         be made in Common Stock valued at fair market value, in cash, or partly
         in Common Stock and partly in cash, all as determined by the Board of
         Directors.

                           (ii) A stock appreciation right shall be exercisable
         only at the time or times established by the Board of Directors. If a
         stock appreciation right is granted in connection with an option, the
         following rules shall apply: (1) the stock appreciation right shall be
         exercisable only to the extent and on the same conditions that the
         related option could be exercised; (2) the stock appreciation rights
         shall be exercisable only when the fair market value of the stock
         exceeds the option price of the related option; (3) the stock
         appreciation right shall be for no more than 100 percent of the excess
         of the fair market value of the stock at the time of exercise over the
         option price; (4) upon exercise of the stock appreciation right, the
         option or portion thereof to which the stock appreciation right relates
         terminates; and (5) upon exercise of the option, the related stock
         appreciation right or portion thereof terminates. Unless otherwise
         determined by

                                       9
<PAGE>

         the Board of Directors, no stock appreciation right granted to an
         Officer or director may be exercised during the first six months
         following the date it is granted.

                           (iii) The Board of Directors may withdraw any stock
         appreciation right granted under the Plan at any time and may impose
         any conditions upon the exercise of a stock appreciation right or adopt
         rules and regulations from time to time affecting the rights of holders
         of stock appreciation rights. Such rules and regulations may govern the
         right to exercise stock appreciation rights granted prior to adoption
         or amendment of such rules and regulations as well as stock
         appreciation rights granted thereafter.

                           (iv) For purposes of this paragraph 9, the fair
         market value of the Common Stock shall be determined as of the date the
         stock appreciation right is exercised, under the methods set forth in
         paragraph 6(b)(iv).

                           (v) No fractional shares shall be issued upon
         exercise of a stock appreciation right. In lieu thereof, cash may be
         paid in an amount equal to the value of the fraction or, if the Board
         of Directors shall determine, the number of shares may be rounded
         downward to the next whole share.

                           (vi) Each stock appreciation right granted in
         connection with an Incentive Stock Option, and unless otherwise
         determined by the Board of Directors with respect to a stock
         appreciation right granted to a person who is neither an Officer nor a
         director of the Company, each other stock appreciation right granted
         under the Plan by its terms shall be nonassignable and nontransferable
         by the holder, either voluntarily or by operation of law, except by
         will or by the laws of descent and distribution of the state or country
         of the holder's domicile at the time of death, and each stock
         appreciation right by its terms shall be exercisable during the
         holder's lifetime only by the holder.

                           (vii) Each participant who has exercised a stock
         appreciation right shall, upon notification of the amount due, pay to
         the Company in cash amounts necessary to satisfy any applicable
         federal, state and local tax withholding requirements. If the
         participant fails to pay the amount demanded, the Company may withhold
         that amount from other amounts payable by the Company to the
         participant including salary, subject to applicable law. With the
         consent of the Board of Directors a participant may satisfy this
         obligation, in whole or in part, by having the Company withhold from
         any shares to be issued upon the exercise that number of shares that
         would satisfy the withholding amount due or by delivering Common Stock
         to the Company to satisfy the withholding amount.

                           (viii) Upon the exercise of a stock appreciation
         right for shares, the number of shares reserved for issuance under the
         Plan shall be reduced by the number

                                       10
<PAGE>

         of shares issued. Cash payments of stock appreciation rights shall
         not reduce the number of shares of Common Stock reserved for issuance
         under the Plan.

         10.      CASH BONUS RIGHTS.

                  (a) GRANT. The Board of Directors may grant cash bonus
rights under the Plan in connection with (i) options granted or previously
granted, (ii) stock appreciation rights granted or previously granted, (iii)
stock bonuses awarded or previously awarded and (iv) shares sold or
previously sold under the Plan. Cash bonus rights will be subject to rules,
terms and conditions as the Board of Directors may prescribe. Unless
otherwise determined by the Board of Directors with respect to a cash bonus
right granted to a person who is neither an Officer nor a director of the
Company, each cash bonus right granted under the Plan by its terms shall be
nonassignable and nontransferable by the holder, either voluntarily or by
operation of law, except by will or by the laws of descent and distribution
of the state or country of the holder's domicile at the time of death. The
payment of a cash bonus shall not reduce the number of shares of Common Stock
reserved for issuance under the Plan.

                  (b) CASH BONUS RIGHTS IN CONNECTION WITH OPTIONS. A cash
bonus right granted in connection with an option will entitle an optionee to
a cash bonus when the related option is exercised (or terminates in
connection with the exercise of a stock appreciation right related to the
option) in whole or in part if, in the sole discretion of the Board of
Directors, the bonus right will result in a tax deduction that the Company
has sufficient taxable income to use. If an optionee purchases shares upon
exercise of an option and does not exercise a related stock appreciation
right, the amount of the bonus, if any, shall be determined by multiplying
the excess of the total fair market value of the shares to be acquired upon
the exercise over the total option price for the shares by the applicable
bonus percentage. If the optionee exercises a related stock appreciation
right in connection with the termination of an option, the amount of the
bonus, if any, shall be determined by multiplying the total fair market value
of the shares and cash received pursuant to the exercise of the stock
appreciation right by the applicable bonus percentage. The bonus percentage
applicable to a bonus right, including a previously granted bonus right, may
be changed from time to time at the sole discretion of the Board of Directors
but shall in no event exceed 75 percent.

                  (c) CASH BONUS RIGHTS IN CONNECTION WITH STOCK BONUS. A
cash bonus right granted in connection with a stock bonus will entitle the
recipient to a cash bonus payable when the stock bonus is awarded or
restrictions, if any, to which the stock is subject lapse. If bonus stock
awarded is subject to restrictions and is repurchased by the Company or
forfeited by the holder, the cash bonus right granted in connection with the
stock bonus shall terminate and may not be exercised. The amount and timing
of payment of a cash bonus shall be determined by the Board of Directors.

                  (d) CASH BONUS RIGHTS IN CONNECTION WITH STOCK PURCHASES. A
cash bonus right granted in connection with the purchase of stock pursuant to
paragraph 8 will entitle

                                       11
<PAGE>

the recipient to a cash bonus when the shares are purchased or restrictions,
if any, to which the stock is subject lapse. Any cash bonus right granted in
connection with shares purchased pursuant to paragraph 8 shall terminate and
may not be exercised in the event the shares are repurchased by the Company
or forfeited by the holder pursuant to applicable restrictions. The amount of
any cash bonus to be awarded and timing of payment of a cash bonus shall be
determined by the Board of Directors.

                  (e) TAXES. The Company shall withhold from any cash bonus
paid pursuant to paragraph 10 the amount necessary to satisfy any applicable
federal, state and local withholding requirements.

         11. PERFORMANCE UNITS. The Board of Directors may grant performance
units consisting of monetary units which may be earned in whole or in part if
the Company achieves certain goals established by the Board of Directors over
a designated period of time, but not in any event more than 10 years. The
goals established by the Board of Directors may include earnings per share,
return on shareholders' equity, return on invested capital, and such other
goals as may be established by the Board of Directors. In the event that the
minimum performance goal established by the Board of Directors is not
achieved at the conclusion of a period, no payment shall be made to the
participants. In the event the maximum corporate goal is achieved, 100
percent of the monetary value of the performance units shall be paid to or
vested in the participants. Partial achievement of the maximum goal may
result in a payment or vesting corresponding to the degree of achievement as
determined by the Board of Directors. Payment of an award earned may be in
cash or in Common Stock or in a combination of both, and may be made when
earned, or vested and deferred, as the Board of Directors determines.
Deferred awards shall earn interest on the terms and at a rate determined by
the Board of Directors. Unless otherwise determined by the Board of Directors
with respect to a performance unit granted to a person who is neither an
Officer nor a director of the Company, each performance unit granted under
the Plan by its terms shall be nonassignable and nontransferable by the
holder, either voluntarily or by operation of law, except by will or by the
laws of descent and distribution of the state or country of the holder's
domicile at the time of death. Each participant who has been awarded a
performance unit shall, upon notification of the amount due, pay to the
Company in cash amounts necessary to satisfy any applicable federal, state
and local tax withholding requirements. If the participant fails to pay the
amount demanded, the Company may withhold that amount from other amounts
payable by the Company to the participant, including salary or fees for
services, subject to applicable law. With the consent of the Board of
Directors a participant may satisfy this obligation, in whole or in part, by
having the Company withhold from any shares to be issued that number of
shares that would satisfy the withholding amount due or by delivering Common
Stock to the Company to satisfy the withholding amount. The payment of a
performance unit in cash shall not reduce the number of shares of Common
Stock reserved for issuance under the Plan. The number of shares reserved for
issuance under the Plan shall be reduced by the number of shares issued upon
payment of an award.

                                       12

         12. FOREIGN QUALIFIED GRANTS. Awards under the Plan may be granted
to such officers and employees of the Company and its subsidiaries and such
other persons described in paragraph 1 residing in foreign jurisdictions as
the Board of Directors may determine from time to time. The Board of
Directors may adopt such supplements to the Plan as may be necessary to
comply with the applicable laws of such foreign jurisdictions and to afford
participants favorable treatment under such laws; provided, however, that no
award shall be granted under any such supplement with terms which are more
beneficial to the participants than the terms permitted by the Plan.

         13.      CHANGES IN CAPITAL STRUCTURE.

                  (a) STOCK SPLITS; STOCK DIVIDENDS. If the outstanding
Common Stock of the Company is hereafter increased or decreased or changed
into or exchanged for a different number or kind of shares or other
securities of the Company by reason of any stock split, combination of shares
or dividend payable in shares, recapitalization or reclassification
appropriate adjustment shall be made by the Board of Directors in the number
and kind of shares available for grants under the Plan. In addition, the
Board of Directors shall make appropriate adjustment in the number and kind
of shares as to which outstanding options, or portions thereof then
unexercised, shall be exercisable, so that the optionee's proportionate
interest before and after the occurrence of the event is maintained.
Notwithstanding the foregoing, the Board of Directors shall have no
obligation to effect any adjustment that would or might result in the
issuance of fractional shares, and any fractional shares resulting from any
adjustment may be disregarded or provided for in any manner determined by the
Board of Directors. Any such adjustments made by the Board of Directors shall
be conclusive.

                  (b) MERGERS, REORGANIZATIONS, ETC. In the event of a
merger, consolidation, plan of exchange, acquisition of property or stock,
separation, reorganization or liquidation to which the Company or a
subsidiary is a party or a sale of all or substantially all of the Company's
assets (each, a "Transaction"), the Board of Directors shall, in its sole
discretion and to the extent possible under the structure of the Transaction,
select one of the following alternatives for treating outstanding options
under the Plan:

                           (i) Outstanding options shall remain in effect in
         accordance with their terms.

                           (ii) Outstanding options shall be converted into
         options to purchase stock in the corporation that is the surviving or
         acquiring corporation in the Transaction. The amount, type of
         securities subject thereto and exercise price of the converted options
         shall be determined by the Board of Directors of the Company, taking
         into account the relative values of the companies involved in the
         Transaction and the exchange rate, if any, used in determining shares
         of the surviving corporation to be issued to holders of shares of the
         Company. Unless otherwise determined by the Board

                                       13
<PAGE>

         of Directors, the converted options shall be vested only to the extent
         that the vesting requirements relating to options granted hereunder
         have been satisfied.

                           (iii) The Board of Directors shall provide a 30-day
         period prior to the consummation of the Transaction during which
         outstanding options may be exercised to the extent then exercisable,
         and upon the expiration of such 30-day period, all unexercised options
         shall immediately terminate. The Board of Directors may, in its sole
         discretion, accelerate the exercisability of options so that they are
         exercisable in full during such 30-day period.

                  (c) DISSOLUTION OF THE COMPANY. In the event of the
dissolution of the Company, options shall be treated in accordance with
paragraph 13(b)(iii).

                  (d) RIGHTS ISSUED BY ANOTHER CORPORATION. The Board of
Directors may also grant options, stock appreciation rights, performance units,
stock bonuses and cash bonuses and issue restricted stock under the Plan having
terms, conditions and provisions that vary from those specified in this Plan
provided that any such awards are granted in substitution for, or in connection
with the assumption of, existing options, stock appreciation rights, stock
bonuses, cash bonuses, restricted stock and performance units granted, awarded
or issued by another corporation and assumed or otherwise agreed to be provided
for by the Company pursuant to or by reason of a Transaction.

         14. AMENDMENT OF PLAN. The Board of Directors may at any time, and from
time to time, modify or amend the Plan in such respects as it shall deem
advisable because of changes in the law while the Plan is in effect or for any
other reason, except that without the approval of the shareholders of the
Company, the Board of Directors may not increase the number of shares authorized
to be issued under paragraph 2 of the Plan (except for adjustments permitted
under paragraph 13(a) of the Plan). Except as provided in paragraphs 6(a)(iv),
9, 10 and 13, however, no change in an award already granted shall be made
without the written consent of the holder of such award.

         15. APPROVALS. The obligations of the Company under the Plan are
subject to the approval of state and federal authorities or agencies with
jurisdiction in the matter. The Company will use its best efforts to take steps
required by state or federal law or applicable regulations, including rules and
regulations of the Securities and Exchange Commission and any stock exchange on
which the Company's shares may then be listed, in connection with the grants
under the Plan. The foregoing notwithstanding, the Company shall not be
obligated to issue or deliver Common Stock under the Plan if such issuance or
delivery would violate applicable state or federal securities laws.


         16. EMPLOYMENT AND SERVICE RIGHTS. Nothing in the Plan or any award
pursuant to the Plan shall (i) confer upon any employee any right to be
continued in the employment of the Company or any subsidiary or interfere in any
way with the right of the Company or any

                                       14
<PAGE>

subsidiary by whom such employee is employed to terminate such employee's
employment at any time, for any reason, with or without cause, or to decrease
such employee's compensation or benefits, or (ii) confer upon any person
engaged by the Company any right to be retained or employed by the Company or
to the continuation, extension, renewal, or modification of any compensation,
contract, or arrangement with or by the Company.

         17. RIGHTS AS A SHAREHOLDER. The recipient of any award under the
Plan shall have no rights as a shareholder with respect to any Common Stock
until the date of issue to the recipient of a stock certificate for such
shares. Except as otherwise expressly provided in the Plan, no adjustment
shall be made for dividends or other rights for which the record date occurs
prior to the date such stock certificate is issued.

         18.      OPTION GRANTS TO NON-EMPLOYEE DIRECTORS.

                  (a) INITIAL BOARD GRANTS. Each person who becomes a
Non-Employee Director after the Plan is adopted shall be automatically
granted an option to purchase 15,000 shares of Common Stock when he or she
becomes a Non-Employee Director, so long as such person has not previously
served as a director of the Company. A "Non-Employee Director" is a director
who is not an employee of the Company or any of its subsidiaries, but does
not include such a director whose employer prohibits such director from
receiving any grant of an option to purchase shares of Common Stock of the
Company.

                  (b) ADDITIONAL GRANTS. Each Non-Employee Director shall be
automatically granted an option to purchase additional shares of Common Stock
in each calendar year subsequent to the year in which such Non-Employee
Director was granted an option pursuant to paragraph 18(a), such option to be
granted as of the date of the Company's annual meeting of shareholders held
in such calendar year, provided that the Non-Employee Director continues to
serve in such capacity as of such date. The number of shares subject to each
additional grant shall be 5,000 shares for each Non-Employee Director.

                  (c) EXERCISE PRICE. The exercise price of all options
granted pursuant to this paragraph 18 shall be equal to 100 percent of the
fair market value of the Common Stock determined pursuant to paragraph
6(b)(iv).

                  (d) TERM OF OPTION.  The term of each option granted
pursuant to this paragraph 18 shall be 10 years from the date of grant.

                  (e) EXERCISABILITY. Until an option expires or is
terminated and except as provided in paragraphs 18(g) and 13, an option
granted under this paragraph 18 shall be exercisable in full on the date one
year following the grant of the option.

                  (f) TERMINATION AS A DIRECTOR. If an optionee ceases to be
a director of the Company for any reason, including death, the option may be
exercised at any time prior to the

                                       15
<PAGE>

expiration date of the option or the expiration of 30 days (or 12 months in
the event of death) after the last day the optionee served as a director,
whichever is the shorter period, but only if and to the extent the optionee
was entitled to exercise the option as of the last day the optionee served as
a director.

                  (g) NONTRANSFERABILITY. Each option by its terms shall be
nonassignable and nontransferable by the optionee, either voluntarily or by
operation of law, except by will or by the laws of descent and distribution
of the state or country of the optionee's domicile at the time of death, and
each option by its terms shall be exercisable during the optionee's lifetime
only by the optionee.

                  (h) EXERCISE OF OPTIONS. Options may be exercised upon
payment of cash or shares of Common Stock of the Company in accordance with
paragraph 6(a)(v).

                        1996 EMPLOYEE STOCK PURCHASE PLAN

                     (As Amended through February 25, 2000)

I.       PURPOSE OF PLAN

         As a means by which Employees may share in the Company's growth and
         success, RadiSys Corporation (the "Company") believes that ownership of
         shares of its Common Stock by its Employees is desirable. To this end,
         and as an incentive to better performance and improved profits, the
         Company has established the RadiSys Corporation 1996 Employee Stock
         Purchase Plan (the "Plan").

         The Company intends that the Plan will constitute an "employee stock
         purchase plan" within the meaning of Section 423 of the Code.

II.      DEFINITIONS

         Terms that are capitalized within this document shall have the meanings
         as set forth in Exhibit A, unless otherwise specified within the text.

III.     EMPLOYEE PARTICIPATION

         PARTICIPATION

         Subject to the provisions of this Section III, an Employee may elect to
         participate in the Plan effective as of any Enrollment Date by
         completing and filing a Payroll Deduction Authorization Form as
         provided in Section IV. As of each Enrollment Date, the Company hereby
         grants a right to purchase Shares under the terms of the Plan to each
         eligible Employee who has elected to participate in the Offering
         commencing on that Enrollment Date.

         A person shall become eligible to participate in the Plan on the first
         Enrollment Date on which that person meets the following requirements:

                        1996 EMPLOYEE STOCK PURCHASE PLAN

                     (As Amended through February 25, 2000)

          a)        The person is an Employee, and

          b)        The person's customary period of Employment is more than
                    twenty (20) hours per week.

         Any eligible Employee may enroll in the Plan as of the Enrollment Date
         of any Offering by filing timely written notice of such participation,
         subject to the following provisions:

         (i)      In order to enroll in the Plan initially, an eligible Employee
                  must complete, sign and submit to the Company the following
                  forms:

                  (A)      PAYROLL DEDUCTION AUTHORIZATION FORM Must be received
                           by the Company at least fifteen (15) days prior to
                           the Enrollment Date of an Offering to be effective
                           for that Offering.

                  (B)      ESPP NEW ACCOUNT FORM This form must accompany the
                           Payroll Deduction Authorization Form submitted for
                           enrollment in the Plan. An ESPP New Account Form must
                           be received by the Company at least fifteen (15) days
                           prior to the Enrollment Date of an Offering to be
                           effective for that Offering.

         (ii)     A Participant in an ongoing Offering may elect as of any
                  Enrollment Date to enroll in the new Offering commencing on
                  that Enrollment Date by filing a Payroll Deduction
                  Authorization Form making such election prior to 4:00 p.m.
                  Pacific Time on the Enrollment Date. An election by a current

                  ongoing Offering and simultaneous reenrollment in the new
                  Offering. A reenrollment shall not affect the purchase of

                  purposes of Section VI is less than it was as of the
                  Enrollment Date for the Offering in which the Participant is
                  currently participating. Unless otherwise specified by the
                  Participant, any such ongoing reenrollment election shall be

                        1996 EMPLOYEE STOCK PURCHASE PLAN

                     (As Amended through February 25, 2000)

                  subject to revocation; provided, however, that to be effective
                  to prevent reenrollment on any Enrollment Date, such
                  revocation must be received by the Company prior to 4:00 p.m.
                  Pacific Time on the Enrollment Date.

         (iii)    Absent withdrawal from the Plan pursuant to Section VII, a
                  Participant will automatically be re-enrolled in the Offering
                  commencing on the Enrollment Date immediately following the
                  expiration of the Offering of which that person is then a
                  Participant.

         A Participant shall become ineligible to participate in the Plan and
         shall cease to be a Participant when the Participant ceases to meet the
         eligibility requirements as defined above.

         LIMITATIONS ON PARTICIPATION

         No Employee may obtain a right to purchase Shares under the Plan if,
         immediately after the right is granted, the Employee owns or is deemed
         to own Shares possessing five percent (5%) or more of the combined
         voting power or value of all classes of stock of the Company or any
         parent or subsidiary of the Company. For purposes of determining share
         ownership, the rules of Section 424(d) of the Code shall apply and
         Shares that the Employee may purchase under any options or rights to
         purchase, whether or not Vested, shall be treated as Shares owned by
         the Employee.

         No Employee may obtain a right to purchase Shares under the Plan that
         permits the Employee's rights to purchase Shares under the Plan and any
         other employee stock purchase plan within the meaning of Section 423 of
         the Code of the Company or any parent or subsidiary of the Company to
         accrue at a rate which exceeds $25,000 in fair market value of Shares
         (determined as of the Enrollment Date) for each calendar year of the
         Offering. This section shall be interpreted to permit an Employee to
         purchase the maximum number of Shares permitted under Section 423(b)(8)
         of the Code and regulations and interpretations adopted thereunder.

                     (As Amended through February 25, 2000)

         The maximum number of Shares that an Employee may purchase in an
         Offering shall not exceed 10,000 shares, no more than one-third of
         which may be purchased on any Purchase Date with respect to that
         Offering.

         VOLUNTARY PARTICIPATION

         Participation in the Plan shall be strictly voluntary.

IV.      PAYROLL DEDUCTIONS

         PAYROLL DEDUCTION AUTHORIZATION

         An Employee may contribute to the Plan only by means of payroll
         deductions. A Payroll Deduction Authorization Form must be filed with
         the Company's stock administrator at least fifteen (15) days prior to
         the Enrollment Date as of which the payroll deductions are to take
         effect.

         AMOUNT OF DEDUCTIONS

         A Participant may specify that the person desires to make contributions
         to the Plan at a rate not less than 1% and not more than 10% of the
         Compensation paid to the Participant during each pay period in the
         Offering, or other such minimum or maximum percentages as the Plan
         Administrator shall establish from time to time. Such specification
         shall apply during any period of continuous participation in the Plan,
         unless otherwise modified or terminated as provided in this Section IV
         or as otherwise provided in the Plan. If a payroll deduction cannot be
         made in whole or in part because the Participant's pay for the period
         in question is insufficient to fund the deduction after having first
         withheld all other amounts deductible from that person's pay, the
         amount that was not withheld cannot be made up by the Participant nor
         will it be withheld from subsequent pay checks.

Initial Adoption: December 5, 1995               Last amended: February 25, 2000

                     (As Amended through February 25, 2000)

         COMMENCEMENT OF DEDUCTIONS

         Payroll deductions for a Participant shall commence on the Enrollment
         Date of the Offering for which that person's Payroll Deduction
         Authorization Form is effective and shall continue indefinitely, unless
         modified or terminated as provided in this Section IV or as otherwise
         provided in the Plan.

         ACCOUNTS

         All payroll deductions made for a Participant shall be credited to his
         or her Account under the Plan. Following each Purchase Date, the Plan
         Administrator shall promptly deliver a report to each Participant
         setting forth the aggregate payroll deductions credited to such
         Participant's Account during the preceding six months and the number of
         Shares purchased and delivered to the Custodian for deposit into the
         Participant's Custodial Account.

         MODIFICATION OF AUTHORIZED DEDUCTIONS

         A Participant may, prior to the commencement of each Offering in which
         that person will be a Participant, and not more than three times during
         each Offering, increase or decrease the amount of that person's payroll
         deduction effective for all applicable payroll periods, by completing
         an amended Payroll Deduction Authorization Form and filing it with the
         Company's stock administrator in accordance with this Section IV.

         A Participant may at any time discontinue the Participant's payroll
         deductions, without withdrawing from the Plan, by completing an amended
         Payroll Deduction Authorization Form and filing it with the Company's
         stock administrator. Previous payroll deductions will then be retained
         in the Participant's Account for application to purchase Shares on the
         next Purchase Date, after which the Participant's participation in the
         Offering and in the Plan will terminate unless the participant has
         timely filed another Payroll Deduction Authorization Form to resume
         payroll deductions.

Initial Adoption: December 5, 1995               Last amended: February 25, 2000

                     (As Amended through February 25, 2000)

         For purposes of the above, an amended Payroll Deduction Authorization
         form shall be effective for a specific pay period when filed 15 days
         prior to the last day of such payroll period.

V.       CUSTODY OF SHARES

         DELIVERY AND CUSTODY OF SHARES

         Shares purchased pursuant to the Plan shall be delivered to and held by
         the Custodian.

         CUSTODIAL ACCOUNT

         As soon as practicable after each Purchase Date, the Company shall
         deliver to the Custodian the full Shares purchased for each
         Participant's Account. The Shares will be held in a Custodial Account
         specifically established for this purpose. An Employee must open a
         Custodial Account with the Custodian in order to be eligible to
         purchase Shares under the Plan. In order to open a Custodial Account,
         the Participant must complete an ESPP New Account Form and file it with
         the stock administrator no later than fifteen (15) days prior to the
         Enrollment Date of the Offering as of which the enrollment is to take
         effect; provided, however, that an ESPP New Account Form that effects a
         change in the status of the Custodial Account may be filed at any time
         during participation in the Plan.

         TRANSFER OF SHARES

         Upon receipt of appropriate instructions from a Participant on forms
         provided for that purpose, the Custodian will transfer into the
         Participant's own name all or part of the Shares held in the
         Participant's Custodial Account and deliver such Shares to the
         Participant.

         The Custodian will deliver to each Participant a semi-annual statement
         showing the activity of the Participant's Custodial Account and the
         balance as to both Shares and cash. Participants will be furnished such
         other reports and statements, and at such intervals, as the Custodian
         and Plan Administrator shall determine from time to time.

VI.      PURCHASE OF SHARES

         PURCHASE OF SHARES

         Subject to the limitations of Section VII, on each Purchase Date in an
         Offering, the Company shall apply the amount credited to each
         Participant's Account to the purchase of as many full Shares that may
         be purchased with such amount at the price set forth in this Section
         VI, and shall promptly deliver such Shares to the Custodian for deposit
         into the Participant's Custodial Account. Payment for Shares purchased
         under the Plan will be made only through payroll withholding deductions
         in accordance with Section IV.

         PRICE

         The price of Shares to be purchased on any Purchase Date shall be the
         lower of:

                  (a)   Eighty-five percent (85%) of the fair market value of
                   the Shares on the Enrollment Date of the Offering; or

                  (b)   Eighty-five percent (85%) of the fair market value of
                   the Shares on the Purchase Date.

         FAIR MARKET VALUE

Initial Adoption: December 5, 1995               Last amended: February 25, 2000

                     (As Amended through February 25, 2000)

         The fair market value of the Shares on any date shall be equal to the
         closing trade price of such shares on the Valuation Date, as reported
         on the NASDAQ National Market System or such other quotation system
         that supersedes it.

         UNUSED CONTRIBUTIONS

         Any amount credited to a Participant's Account and remaining therein
         immediately after a Purchase Date because it was less than the amount
         required to purchase a full Share shall be carried forward in such
         Participant's Account for application on the next succeeding Purchase
         Date.

VII.     TERMINATION AND WITHDRAWAL

         TERMINATION OF EMPLOYMENT

         Upon termination of a Participant's Employment for any reason other
         than death, the payroll deductions credited to such Participant's
         Account shall be returned to the Participant. A Participant shall have
         no right to accrue Shares upon termination of the person's Employment.

         TERMINATION UPON DEATH

         Upon termination of the Participant's Employment because of that
         person's death, the payroll deductions credited to that person's
         Account shall be used to purchase Shares as provided in Section VI on
         the next Purchase Date. Any Shares purchased and any remaining balance
         shall be transferred to the deceased Participant's Beneficiary, or if
         none, to that person's estate.

         DESIGNATION OF BENEFICIARY

         Each Participant may designate, revoke, and redesignate Beneficiaries.
         All changes to designation of Beneficiary shall be in writing and will
         be effective upon delivery to the Plan Administrator.

         WITHDRAWAL

         A Participant may withdraw the entire amount credited to that
         individual's Account under the Plan and thereby terminate participation
         in the current Offering at any time by giving written notice to the
         Company, but in no case may a Participant withdraw accounts within the
         15 days immediately preceding a Purchase Date for the Offering. Any
         amount withdrawn shall be paid to the Participant promptly after
         receipt of proper notice of withdrawal and no further payroll
         deductions shall be made from the person's Compensation unless a
         Payroll Deduction Authorization Form directing further deductions is or
         has been submitted.

         STATUS OF CUSTODIAL ACCOUNT

         Upon termination of a Participant's Employment for any reason other

                  (a)   Elect to retain with the Custodian the Shares held in
                  the Participant's Custodial Account. The Participant will bear
                  the cost of any annual fees resulting from maintaining such an
                  account.

                  (b)   Request issuance of the Shares held in the Participant's
                  Custodial Account by submitting to the Custodian the
                  appropriate forms provided for that purpose.

         Upon termination of a Participant's Employment as a result of death,
         any Shares held by the Custodian for the Participant's Account shall be
         transferred to the person(s) entitled thereto under the laws of the
         state of domicile of the Participant upon a proper showing of
         authority.

                     (As Amended through February 25, 2000)

VIII.    SHARES PURCHASED UNDER THE PLAN

         SOURCE AND LIMITATION OF SHARES

         The Company has reserved for sale under the Plan 750,000* shares of
         common stock, subject to adjustment upon changes in capitalization of
         the Company as provided in Section X. Shares sold under the Plan may be
         newly issued Shares or Shares reacquired in private transactions or
         open market purchases, but all Shares sold under the Plan regardless of
         source shall be counted against the 750,000* Share limitation.

         If there is an insufficient number of Shares to permit the full
         exercise of all existing rights to purchase Shares, or if the legal
         obligations of the Company prohibit the issuance of all Shares
         purchasable upon the full exercise of such rights, the Plan
         Administrator shall make a pro rata allocation of the Shares remaining
         available in as nearly a uniform and equitable manner as possible,
         based pro rata on the aggregate amounts then credited to each
         Participant's Account. In such event, payroll deductions to be made
         shall be reduced accordingly and the Plan Administrator shall give
         written notice of such reduction to each Participant affected thereby.
         Any amount remaining in a Participant's Account immediately after all
         available Shares have been purchased will be promptly remitted to such
         Participant. Determination by the Plan Administrator in this regard
         shall be final, binding and conclusive on all persons. No deductions
         shall be permitted under the Plan at any time when no Shares are
         available.

        * Adjusted to reflect a 3-for-2 split of the share of Common Stock,
without par value, of the Company, effected in the form of a 50% share dividend
in accordance with ORS 60.154, declared by the Board of Directors on October 19,
1999, and paid on November 29, 1999 to shareholders of record at the close of

                     (As Amended through February 25, 2000)

         DELIVERY OF SHARES

         As promptly as practicable after each Purchase Date, the Company shall
         deliver to the Custodian the full Shares purchased for each
         Participant's Account.

         INTEREST IN SHARES

         The rights to purchase Shares granted pursuant to this Plan will in all
         respects be subject to the terms and conditions of the Plan, as
         interpreted by the Plan Administrator from time to time. The
         Participant shall have no interest in Shares purchasable under the Plan
         until payment for the Shares has been completed at the close of
         business on the relevant Purchase Date. The Plan provides only an
         unfunded, unsecured promise by the Company to pay money or property in
         the future. Except with respect to the Shares purchased on a Purchase
         Date, an Employee choosing to participate in the Plan shall have no
         greater rights than an unsecured creditor of the Company. After the
         purchase of Shares, the Participant shall be entitled to all rights of
         a stockholder of the Company.

IX.      ADMINISTRATION

         PLAN ADMINISTRATOR

         At the discretion of the Board of Directors, the Plan shall be
         administered by the Board of Directors or by a Committee appointed by
         the Board of Directors. Each member of the Committee shall be either a
         director, an officer or an Employee of the Company. Each member shall
         serve for a term commencing on a date specified by the Board of
         Directors and continuing until that person dies, resigns or is removed
         by the Board of Directors.

         POWERS

         The Plan Administrator shall be vested with full authority to make,
         administer and interpret the rules and regulations as it deems
         necessary to administer the Plan. Any determination, decision or act of
         the Plan Administrator with respect to any action in

         connection with the construction, interpretation, administration or
         application of the Plan shall be final, binding and conclusive upon all
         Participants and any and all other persons claiming under or through
         any Participant. The provisions of the Plan shall be construed in a
         manner consistent with the requirements of Section 423 of the Code.

X.       CHANGES IN CAPITALIZATION, MERGER, ETC.

         RIGHTS OF THE COMPANY

         The grant of a right to purchase Shares pursuant to this Plan shall not
         affect in any way the right or power of the Company to make
         adjustments, reclassifications, reorganizations or other changes in its
         capital or business structure or to merge, consolidate or dissolve,
         liquidate or transfer all or any part of its divisions, subsidiaries,
         business or assets.

         RECAPITALIZATION

         Subject to any required action by stockholders, the number of Shares
         covered by the Plan as provided in Section VIII and the price per Share
         shall be proportionately adjusted for any increase or decrease in the
         number of issued Shares of the Company resulting from a subdivision or
         consolidation of Shares or the payment of a stock dividend or any other
         increase or decrease in the number of such Shares effected without
         receipt or payment of consideration by the Company.

         CONSOLIDATION OR MERGER

         In the event of the consolidation or merger of the Company with or into
         any other business entity, or sale by the Company of substantially all
         of its assets, the successor may at its discretion continue the Plan by
         adopting the same by resolution of its Board of Directors or agreement
         of its partners or proprietors. If, within 90 days after the effective
         date of a consolidation, merger, or sale of assets, the successor
         corporation, partnership or proprietorship does not adopt the Plan, the
         Plan shall be terminated in accordance with Section XIII.

         VACATION, LEAVE OR LAYOFF

         A person's Employment shall not terminate on account of an authorized
         leave of absence, sick leave or vacation, or on account of a military
         leave described in this Section XI, or a direct transfer between
         Employers, provided such leave does not exceed 90 days or, if longer,
         so long as the person's right to reemployment is guaranteed by statute
         or by contract. Failure to return to work upon expiration of any leave
         of absence, sick leave or vacation shall be considered a resignation
         effective as of the expiration of such leave of absence, sick leave or
         vacation.

         MILITARY LEAVE

         Any Employee who leaves the Employer directly to perform services in
         the Armed Forces of the United States or in the United States Public
         Health Service under conditions entitling the Employee to reemployment
         rights provided by the laws of the United States, shall be on military
         leave. An Employee's military leave shall expire if the Employee
         voluntarily resigns from the Employer during the leave or if that
         person fails to make an application for reemployment within a period
         specified by such law for preservation of employment rights. In such
         event, the individual's Employment shall terminate by resignation on
         the day the military leave expires.

XII.     STOCKHOLDER APPROVAL AND RULINGS

         The Plan is expressly made subject to (a) the approval of the Plan
         within twelve (12) months after the Plan is adopted by the stockholders
         of the Company and (b) at the Company's election, to the receipt by the
         Company from the Internal Revenue Service of a ruling in scope and
         content satisfactory to counsel to the Company, affirming qualification
         of the Plan within the meaning of Section 423 of the Code. If the Plan
         is not so approved by the stockholders within 12 months after the date
         the Plan is adopted

         Revenue Service is sought but not received on or before one year after
         this Plan's adoption by the Board of Directors, this Plan shall not
         come into effect. In that case, the Account of each Participant shall
         forthwith be paid to the Participant.

XIII.    MISCELLANEOUS PROVISIONS

         AMENDMENT AND TERMINATION OF THE PLAN

         The Board of Directors of the Company may at any time amend the Plan.
         Except as otherwise provided herein, no amendment may adversely affect
         or change any right to purchase Shares without prior approval of the
         stockholders of the Company if the amendment would:

         (i)      Permit the sale of more Shares than are authorized under
                  Section VIII;

         (ii)     Permit the sale of Shares to employees of entities which are
                  not Employers;

         (iii)    Materially increase the benefits accruing to Participants
                  under the Plan; or

         (iv)     Materially modify the requirements as to eligibility for
                  participation in the Plan.

         The Plan is intended to be a permanent program, but the Company
         reserves the right to declare the Plan terminated at any time. Upon
         such termination, amounts credited to the Accounts of the Participants
         with respect to whom the Plan has been terminated shall be returned to
         such Participants.

         NON-TRANSFERABILITY

         Neither payroll deductions credited to a Participant's Account nor any
         rights with regard to the purchase of Shares under the Plan may be
         assigned, transferred, pledged or otherwise disposed of in any way by
         the Participant except as provided in Section VII, and any attempted
         assignment, transfer, pledge, or other disposition shall be null and
         void. The Company may treat any such act as an election to withdraw

         funds in accordance with Section VII. A Participant's rights to
         purchase Shares under the Plan are exercisable during the Participant's
         lifetime only by the Participant.

         USE OF FUNDS

         All payroll deductions received or held by the Company under the Plan
         may be used by the Company for any corporate purposes and the Company
         shall not be obligated to segregate the payroll deductions.

         EXPENSES

         All expenses of administering the Plan shall be borne by the Company.
         The Company will not pay expenses, commissions or taxes incurred in
         connection with sales of Shares by the Custodian at the request of a
         Participant. Expenses to be paid by a Participant will be deducted from
         the proceeds of sale prior to remittance.

         TAX WITHHOLDING

         Each Participant who has purchased Shares under the Plan shall
         immediately upon notification of the amount due, if any, pay to the
         Employer in cash amounts necessary to satisfy any applicable federal,
         state and local tax withholding determined by the Employer to be
         required. If the Employer determines that additional withholding is
         required beyond any amounts deposited at the time of purchase, the
         Participant shall pay such amount to the Employer on demand. If the
         Participant fails to pay the amount demanded, the Employer may withhold
         that amount from other amounts payable by the Employer to the
         Participant, including salary, subject to applicable law.

         for interest with respect to or on the payroll deductions contemplated
         herein, or on any other assets held hereunder for the Participant's
         Account.

         REGISTRATION AND QUALIFICATION OF SHARES

         The offering of Shares hereunder shall be subject to the effecting by
         the Company of any registration or qualification of the Shares under
         any federal or state law or the obtaining of the consent or approval of
         any governmental regulatory body which the Company shall determine, in
         its sole discretion, is necessary or desirable as a condition to, or in
         connection with, the offering or the issue or purchase of the Shares
         covered thereby. The Company shall make every reasonable effort to
         effect such registration or qualification or to obtain such consent or
         approval.

         RESPONSIBILITY AND INDEMNITY

         Neither the Company, its Board of Directors, the Custodian, nor any
         member, officer, agent or employee of any of them, shall be liable to
         any Participant under the Plan for any mistake of judgment or for any
         omission or wrongful act unless resulting from gross negligence,
         willful misconduct or intentional misfeasance. The Company will
         indemnify and save harmless its Board of Directors, the Custodian and
         any such member, officer, agent or employee against any claim, loss,
         liability or expense arising out of the Plan, except such as may result
         from the gross negligence, willful misconduct or intentional
         misfeasance of such entity or person.

         PLAN NOT A CONTRACT OF EMPLOYMENT

         The Plan is strictly a voluntary undertaking on the part of the
         Employer and shall not constitute a contract between the Employer and
         any Employee, or consideration for or an inducement or a condition of
         employment of an Employee. Except as otherwise required by law, or any
         applicable collective bargaining agreement, nothing contained in the
         Plan shall give any Employee the right to be retained in the service of
         the

         which is hereby expressly reserved, to discharge or retire any
         Employee at any time, with or without cause and with or without
         notice. Except as otherwise required by law, inclusion under the Plan
         will not give any Employee any right or claim to any benefit hereunder
         except to the extent such right has specifically become fixed under the
         terms of the Plan. The doctrine of substantial performance shall have
         no application to any Employee, Participant, or Beneficiary. Each
         condition and provision, including numerical items, has been carefully
         considered and constitutes the minimum limit on performance which will
         give rise to the applicable right.

         SERVICE OF PROCESS

         The Secretary of the Company is hereby designated agent for service or
         legal process on the Plan.

         NOTICE

         All notices or other communications by a Participant to the Company
         under or in connection with the Plan shall be deemed to have been duly
         given when received by the Plan Administrator. Any notice required by
         the Plan to be received by the Company prior to an Enrollment Date,
         payroll period or other specified date, and received by the Plan
         Administrator subsequent to such date shall be effective on the next
         occurring Enrollment Date, payroll period or other specified date to
         which such notice applies.

         GOVERNING LAW

         The Plan shall be interpreted, administered and enforced in accordance
         with the Code, and the rights of Participants, former Participants,
         Beneficiaries and all other persons shall be determined in accordance
         with it. To the extent state law is applicable, the laws of the State
         of Oregon shall apply.
