ITEM 1. BUSINESS

This Report contains forward-looking statements within the meaning of Section 
27A of the Securities Act of 1933, as amended, and Section 21E of the 
Securities Exchange Act of 1934, as amended.  Actual results could differ 
materially from those projected in the forward-looking statements as a result

in this Report.     

GENERAL

Lattice Semiconductor Corporation (the "Company") designs, develops and 
markets high performance programmable logic devices ("PLDs") and related 
development system software. The Company is the inventor and world's leading 
supplier of in-system programmable ("ISP-TM-") PLDs. PLDs are standard 
semiconductor components that can be configured by the end customer as 
specific logic functions, enabling shorter design cycle times and reduced 
development costs. Lattice products are sold worldwide through an extensive 
network of independent sales representatives and distributors, primarily to 
original equipment manufacturers ("OEMs") of communications, computing, 
industrial controls and military systems. Lattice was founded in 1983 and is 
based in Hillsboro, Oregon.

PLD MARKET BACKGROUND

Three principal types of digital integrated circuits are used in most 
electronic systems: microprocessors, memory and logic. Microprocessors are 
used for control and computing tasks, memory is used to store programming 
instructions and data, and logic is employed to manage the interchange and 
manipulation of digital signals within a system. Logic contains 
interconnected groupings of simple logical "AND" and logical "OR" functions, 
commonly described as "gates". Typically, complex combinations of individual 
gates are required to implement the specialized logic functions required for 
systems applications. While system designers use a relatively small number of 
standard architectures to meet their microprocessor and memory needs, they 
require a wide variety of logic circuits in order to achieve end product 
differentiation. 

Logic circuits are found in a wide range of today's electronic systems 
including communications equipment, computers, peripherals, instrumentation, 
industrial controls and military systems. According to Integrated Circuit 
Engineering Corporation, a semiconductor market research firm, logic 
accounted for approximately 35 % of the estimated $108 billion worldwide 
digital integrated circuit market in 1997. The logic market encompasses, 
among other segments, standard logic, custom-designed application specific 
integrated circuits ("ASICs", which include conventional gate-arrays, 
standard cells and full custom logic circuits), and PLDs. 

Manufacturers of electronic systems are increasingly challenged to bring 
differentiated products to market quickly. These competitive pressures often 
preclude the use of custom-designed ASICs, which generally entail significant 
design risks and time delay. Standard logic products, an alternative to 
custom-designed ASICs, limit a manufacturer's flexibility to adequately 
customize an end system. Programmable logic addresses this inherent dilemma. 
PLDs are standard products, purchased by systems manufacturers in a "blank" 
state, that can be custom configured into a virtually unlimited number of 
specific logic functions by programming the device with electrical signals. 
PLDs give system designers the ability to quickly create their own custom 
logic functions to provide product differentiation without sacrificing rapid 
time to market. Certain PLD products, including the Company's, are 
reprogrammable, meaning that the logic configuration can be modified, if 
needed, after the initial 

                                      2

<PAGE>

programming. In-system programmable PLDs, first pioneered by the Company, 
extend the flexibility of standard reprogrammable PLDs by allowing the system 
designer to configure and reconfigure the logic functions of the PLD with 
standard 5-volt or 3.3-volt power supplies without removing the PLD from the 
system board. 

Several common PLD market segments currently exist. These include low-density 
PLDs (less than 1,000 logic gates) and high-density PLDs (greater than 1,000 
logic gates). High-density PLD devices include devices based on both complex 
PLD ("CPLD") architectures and field programmable gate array ("FPGA") 
architectures. 

Products in each high-density PLD architecture are generally optimal for 
different types of logic functions, although many logic functions can be 
implemented using either type of architecture. CPLDs are characterized by a 
regular building block structure of wide-input logic cells, termed 
macrocells, and use of a centralized logic interconnect scheme. CPLDs are 
optimal for control logic applications, such as state machines, bus 
arbitration, encoders, decoders and sequencers. FPGAs are characterized by a 
narrow-input logic cell and use a distributed interconnect scheme. FPGAs are 
optimal for register intensive and data path logic applications such as 
interface logic and arithmetic functions. The Company believes that a 
substantial portion of high-density PLD customers utilize both CPLD and FPGA 
architectures within a single system design, partitioning logic functions 
across multiple devices to optimize overall system performance and cost. 

TECHNOLOGY

The Company believes that electrically erasable CMOS (Lattice's 
"E2CMOS-Registered Trademark-") is the preferred process technology for PLD 
products due to its inherent performance, reprogrammability and testability 
benefits. E2CMOS technology, through its fundamental ability to be programmed 
and erased electronically, serves as the foundation for the Company's ISP 
products. 

IN-SYSTEM PROGRAMMABLE (ISP) PRODUCTS AND TECHNOLOGY

The Company has pioneered the development of ISP products, based on a 
proprietary technology, which affords it a competitive advantage in the PLD 
market. In contrast to standard PLDs, ISP devices can be configured and 
reconfigured by the system designer without being removed from the printed 
circuit board. Standard E2CMOS programmable logic devices require 12-volt 
electrical signals for programming and therefore must be removed from the 
printed circuit board and programmed using stand alone, specialized hardware, 
while ISP devices can be programmed with standard 5-volt or 3.3-volt 
electrical signals. ISP devices offer enhanced flexibility versus standard 
PLDs, providing a number of important benefits to a system manufacturer 
across the full spectrum of an electronic system product cycle. ISP devices 
can allow customers to reduce design cycle times, accelerate time to market, 
reduce prototyping costs, reduce manufacturing costs and lower inventory 
requirements. ISP devices can also provide customers the opportunity to 
perform simplified and cost-effective field reconfiguration through a data 
file transferred by computer disk or serial data signal.  

 E2CMOS PROCESS TECHNOLOGY

The Company's current silicon product offerings, including its ISP products, 
are based on the Company's proprietary E2CMOS manufacturing process 
technology, termed UltraMOS-Registered Trademark-. The Company's current 
production processes, UltraMOS IV, UltraMOS V and UltraMOS VI are sub-micron 
CMOS technologies.

                                      3

<PAGE>

In comparison to bipolar technology, at one time the dominant technology for 
PLDs, E2CMOS technology consumes less power and generates less heat while 
operating at comparable speed. Additionally, in contrast to 
one-time-programmable bipolar PLDs, E2CMOS PLDs are fully erasable and 
reprogrammable, providing greater end customer design flexibility and 
allowing the PLD manufacturer to fully test all programmable elements in a 
device prior to shipment. An alternative CMOS technology, Erasable 
Programmable Read Only Memory ("EPROM"), provides the same low power 
consumption benefits as E2CMOS, but requires ultraviolet light exposure for 
erasure, necessitating expensive quartz windowed packages and limiting 
testability. Antifuse and Static Random Access Memory ("SRAM") technologies, 
used primarily in the manufacture of high-density FPGAs, offer certain 
advantages for very dense logic devices, but also have significant drawbacks 
when compared with E2CMOS. Antifuse technology is non-erasable, 
non-reprogrammable and subject to lengthy initial programming times that can 
hinder usage in volume production applications. SRAM technology is volatile 
(erases when electrical power is removed), and as such programmable SRAM 
FPGAs require additional non-volatile memory, typically on a separate device, 
to store programming code. This adds cost and printed circuit board area to a 
design, and results in the devices not being completely functional at initial 
system power-up. 

PRODUCTS

ISP PRODUCTS

SILICON.  The Company first entered the ISP market in fiscal 1993 and 
currently offers six distinct families of ISP products, each consisting of 
multiple devices. The Company is currently shipping over 200 speed, package 
and temperature range combinations of its ISP products.

ISPLSI-Registered Trademark- 1000/E:  The Company's original ISP family 
utilizes an innovative, proprietary CPLD architecture incorporating familiar 
GAL-Registered Trademark- ("Generic Array Logic") based logic building 
blocks. This family provides performance of up to 125 MHz (7.5 nanosecond

nanosecond propagation delay), the ispGAL family is available in both 5-volt 
and 3.3-volt operating supply versions.

ISPGDX-TM-:   The ispGDX family, introduced in fiscal 1998, extends in-system 
programmability to the circuit board level using an innovative, new digital 
cross-point switch architecture.  Offered with propagation delays as low as 
5.0 nanoseconds, up to 160 I/O and complete pin-to-pin signal routing, the 
ispGDX is targeted towards digital signal interconnect and interface 
applications.

The Company plans to continue to introduce new families of ISP products, as 
well as improve the performance of existing product families based on market 
needs. 

SOFTWARE DEVELOPMENT TOOLS.  All of the Company's ISP products are supported 
by the Company's ispDS-Registered Trademark- software development tools and 
ispDS+-TM- software development tools (referred to as "fitters"). Designed to 
be a low cost, fully integrated development tool, ispDS runs under the 
Microsoft Windows operating system on a personal computer. ispDS software 
allows a customer to enter and verify a logic design, perform logic 
minimization, assign I/O pins and critical speed paths, simulate timing, 
execute automatic place and route tasks and download a program to an ISP 
device. Designed to provide a seamless integration of the Company's 
development tools with standard design environments, ispDS+ software 
leverages customers' existing investments in third-party CAE tools. Optimized 
for HDL synthesis, ispDS+ software supports all popular third party CAE 
development tool environments running on IBM compatible personal computers as 
well as workstations from Sun Microsystems and Hewlett-Packard. The Company 
offers ispDS+ products supporting common third party CAE design tool 
environments, including ABEL, Cadence, Data I/O, Exemplar, Logical Devices, 
Mentor Graphics, OrCAD, Synario, Synopsys, Synplicity and ViewLogic. ispDS+ 
software allows a customer to compile a design developed in a third party 
environment, assign I/O pins and critical speed paths, simulate and analyze 
timing, execute automatic place and route tasks and download a program to an 
ISP device. In fiscal 1998, the Company released new versions of its existing 
ispDS and ispDS+ software development tools to enhance performance, 
functionality and ease of use.

The Company also provides several software algorithms that support in-system 
programming of the Company's ISP devices. These software products include 
ispCODE-TM-, Turbo ispDOWNLOAD-TM-, ispREMOTE-TM- and ispATE-TM-. ispATE 
enables ISP product programming to be integrated into automatic test 
equipment ("ATE") on the manufacturing floor.  

During fiscal 1998, the number of installed seats of the Company's software 
development tools, as measured by the Company, grew from over 17,000 to 
approximately 25,000. The Company plans to continue to enhance and expand its 
development tool offerings.

NON-ISP PRODUCTS

The Company offers the industry's broadest line of low-density CMOS PLDs 
based on its 16 families of GAL products offered in over 180 speed, power, 
package and temperature range combinations. GAL devices range in complexity 
from approximately 200 to 1,000 logic gates and are typically assembled in 
20-, 24-and 28-pin 

                                      5

<PAGE>

standard dual in-line packages and in 20- and 28-pin standard plastic leaded 
chip carrier packages. The Company offers the industry standard GAL16V8, 
GAL20V8, GAL22V10, GAL20RA10 and GAL20XV10 architectures in a variety of 
speed grades, with propagation delays as low as 3.5 nanoseconds, the highest 
performance in the industry. The Company also offers several proprietary 
extension architectures, the GAL26CV12, GAL18V10, GAL16VP8, GAL20VP8, 
GAL6001/2, GAL16V8Z and GAL20V8Z, each of which is optimized for specific 
applications. The Company also offers a full range of 3.3-volt industry 
standard architectures, the GAL16LV8, GAL20LV8, GAL22LV10 and GAL26CLV12 in a 
variety of speed grades, with propagation delays as low as 3.5 nanoseconds, 
the highest performance in the industry.

The Company's non-ISP products are supported by industry standard software 
and hardware development tools marketed by independent manufacturers 
specifically for PLD applications.

PRODUCT DEVELOPMENT

The Company places great emphasis on product development and believes that 
continued investment in the development of new products that exploit market 
trends is required to maintain its competitive position. The Company's 
product development activities emphasize new proprietary ISP products, 
performance enhancement and cost reduction of existing products, improvements 
of its E2CMOS processes technologies and extension and enhancement of its 
software development tools. Product development activities occur in the 
Company's Hillsboro, Oregon headquarters, its Milpitas, California product 
development center, and its Shanghai, China design center. 

Research and development expenses were $26.8 million, $27.8 million and $32.0 
million in fiscal years 1996, 1997 and 1998, respectively. The Company 
expects to continue to make significant investments in research and 
development in the future. 

OPERATIONS

The Company does not manufacture its silicon wafers. The Company has 
historically maintained strategic relationships with large semiconductor 
manufacturers in order to source its finished silicon wafers, allowing the 
Company to focus its internal resources on product, process and market 
development. In addition, assembly is performed for the Company by outside 
suppliers. The Company performs certain test operations and reliability and 
quality assurance processes internally, as the Company believes it can add 
significant customer value in these areas.  The Company has achieved ISO 9001 
quality certification, an indication of the Company's high internal 
operational standards. 

WAFER FABRICATION

The majority of the Company's silicon wafer requirements are currently 
supplied by Seiko Epson Corporation ("Seiko Epson") in Japan pursuant to an 
agreement with S MOS Systems, Inc. ("S MOS"), an affiliated U.S. distributor 
of Seiko Epson. See "Licenses and Agreements - Seiko Epson/S MOS." The 
Company negotiates wafer volumes, prices and terms with Seiko Epson and S MOS 
on a periodic basis. In addition, the Company receives silicon wafers from 
United Microelectronics Corporation ("UMC") in Taiwan pursuant to a series of 
agreements entered into in 1995. Wafer prices and other purchase terms 
related to this commitment are subject to periodic adjustment.  See " 
Licenses and Agreements - UMC." A significant interruption in supply from 
Seiko Epson 

                                      6

<PAGE>

through S MOS or from UMC would have a material adverse effect on the 
Company's business. See "Factors Affecting Future Results." 

ASSEMBLY

After wafer fabrication and initial testing, the Company ships wafers to 
independent subcontractors for assembly. During assembly, wafers are 
separated into individual die and encapsulated in plastic or ceramic 
packages. Presently, the Company has qualified long-term assembly partners in 
Hong Kong, Malaysia, the Philippines, South Korea, Taiwan and the United 
States. 

TESTING

The Company electrically tests the die on each wafer prior to shipment for 
assembly. Following assembly, prior to customer shipment, each product 
undergoes final testing using test equipment, techniques and quality 
assurance procedures. Final testing on certain products is performed at 
independent contractors in Malaysia, the Philippines, South Korea and the 
United States. 

MARKETING, SALES AND CUSTOMERS

The Company sells its products directly to end customers through a network of 
independent sales representatives and indirectly through a network of 
distributors. The Company utilizes a direct sales management and field 
applications engineering organization in combination with manufacturers' 
representatives and distributors to reach a broad base of potential end 
customers. The Company's end customers are primarily original equipment 
manufacturers in the fields of communications, computing, industrial controls 
and military systems. The Company believes its distribution channel is a 
cost-effective means of reaching end customers. 

At March 28, 1998, the Company had 20 sales representatives and five 
distributors in the United States and Canada. In North America, Arrow 
Electronics, Inc., Hamilton Hallmark, Insight Electronics, Inc. and Marshall 
Industries provide nationwide distribution, while Future Electronics provides 
regional distribution coverage in Canada. The Company has established sales 
channels in over 30 foreign countries through a network of over 30 sales 
representatives and distributors. Approximately one-half of the Company's 
North American sales and most of its foreign sales are made through 
distributors. 

The Company protects each of its North American distributors and some of its 
foreign distributors against reductions in published prices, and expects to 
continue this policy in the foreseeable future. The Company also allows 
returns from these distributors of unsold products under certain conditions. 
For these reasons, the Company does not recognize revenue until products are 
resold by these distributors. 

The Company provides technical and marketing assistance to its end customers 
and sales force with engineering staff based in the Company's headquarters, 
design centers and selected field sales offices. The Company maintains 22 
domestic and international sales offices where the Company's field sales 
managers and applications engineers are based. These offices are located in 
the metropolitan areas of Atlanta, Austin, Boston, Chicago, Dallas, Los 
Angeles, Minneapolis, Orlando, Portland, Raleigh, San Diego, San Jose, Hong 
Kong, London, Milan, Munich, Paris, Seoul, Shanghai, Stockholm, Taipei and 
Tokyo.

International revenues, including those from Canada, accounted for 48%, 49% 
and 51% of the Company's revenues in fiscal 1996, 1997 and 1998, 
respectively. Revenues from Europe were $37.9 million, $39.9 million and 
$61.2 million, and from Asia were $52.4 million, $52.6 million and $ 55.9 
million, in fiscal 1996, 1997 and 1998, respectively. Both international and 
domestic revenues are generally invoiced in U.S. dollars, with the exception 
of sales in Japan, which are invoiced in yen. 

The Company's products are sold to a large and diverse group of customers. No 
individual OEM customer accounted for more than 6% of revenue in either 
fiscal 1996, 1997 or 1998. One distributor accounted for approximately 11% of 
revenue in fiscal 1996.  No distributor accounted for more than 10% of 
revenue in either fiscal 1997 or fiscal 1998.

The Company's sales are primarily executed against purchase orders for 
standard products. Customers frequently revise quantities and delivery 
schedules, without penalty. The Company therefore does not believe that 
backlog as of any given date is indicative of future revenue. 

COMPETITION

The semiconductor industry overall is intensely competitive and is 
characterized by rapid technological change, rapid rates of product 
obsolescence and price erosion. The Company's current and potential 
competitors include a broad range of semiconductor companies, ranging from 
very large, established companies to emerging companies, many of which have 
greater financial, technical, manufacturing, marketing and sales resources 
than the Company. 

The principal competitive factors in the PLD market include silicon product 
features, price, customer support, and sales, marketing and distribution 
strength. The availability of competitive software development tools is also 
critical. In addition to product features such as speed, power consumption, 
reprogrammability, design flexibility and reliability, competition in the PLD 
market occurs on the basis of price and market acceptance of specific 
products and technology. The Company believes that it competes favorably with 
respect to each of these factors. The Company intends to continue to address 
these competitive factors by working to continually introduce product 
enhancements and new products, by seeking to establish its products as 
industry standards in their respective markets, and by working to reduce the 
manufacturing cost of its products over their respective life cycles. 

In the ISP PLD market, the Company primarily competes directly with Altera, 
Advanced Micro Devices ("AMD") and Xilinx, all of which offer competing 
products. The Company also competes indirectly with other PLD suppliers as 
well as other semiconductor companies providing non-PLD based logic 
solutions. As the Company and these other companies seek to expand their 
markets, competition may increase. 

In the non-ISP, low-density, PLD market, the Company competes primarily with 
AMD, a licensee of the Company's GAL patents, which offers a full line of 
E2CMOS GAL-compatible PLDs. Atmel and Cypress Semiconductor offer products 
based on similar and competing CMOS technologies and architectures; however, 
these companies do not offer full product lines. 

Although to date the Company has not experienced significant competition from 
companies located outside the United States, such companies may become a more 
significant competitive factor in the future. As the Company and its current 
competitors seek to expand their markets, competition may increase. Any such 
increases in competition could have a material adverse effect on the 
Company's operating results.

PATENTS

The Company seeks to protect its products and wafer fabrication process 
technologies primarily through patents, trade secrecy measures, copyrights, 
mask work protection, trademark registrations, licensing restrictions, 
confidentiality agreements and other approaches designed to protect 
proprietary information. There can be no assurance that others may not 
independently develop competitive technology not covered by the Company's 
intellectual property rights or that measures taken by the Company to protect 
its technology will be effective. 

The Company holds domestic, European and Japanese patents on its PLD products 
and has patent applications pending in the United States, Japan and Europe. 
There can be no assurance that pending patent applications or other 
applications that may be filed will result in issued patents, or that any 
issued patents will survive challenges to their validity. Although the 
Company believes that its patents have value, there can be no assurance that 
the Company's patents, or any additional patents that may be issued in the 
future, will provide meaningful protection from competition. The Company 
believes its success will depend primarily upon the technical expertise, 
experience, creativity and the sales and marketing abilities of its 
personnel. 

Patent and other proprietary rights infringement claims are common in the 
semiconductor industry. There can be no assurance that, with respect to 
claims made against the Company, the Company could obtain a license on terms 
or under conditions that would not have a material adverse effect on the 
Company. 

LICENSES AND AGREEMENTS

SEIKO EPSON/S MOS

S MOS, an affiliated U.S. distributor of Seiko Epson, has agreed to provide 
manufactured wafers to the Company in quantities based on six-month rolling 
forecasts provided by the Company. The Company has committed to buy certain 
minimum quantities of wafers per month. Wafers for the Company's products are 
manufactured in Japan at Seiko Epson's wafer fabrication facilities and are 
delivered to the Company by S MOS. Prices for the wafers obtained from S MOS 
are reviewed and adjusted periodically and may be adjusted to reflect 
prevailing currency exchange rates. See "Factors Affecting Future Results." 
Daniel S. Hauer, a member of the Company's Board of Directors, is Chairman of 
the Board of Directors of S MOS. 

In July 1994, the Company entered into an advance production payment 
agreement with Seiko Epson and S MOS, under which it advanced to Seiko Epson 
$42 million during fiscal 1995 to be used by Seiko Epson to finance 
additional sub-micron semiconductor wafer manufacturing capacity. Under the 
terms of the agreement, the advance is to be repaid in the form of advanced 
technology sub-micron semiconductor wafers. In conjunction with the advance 
production payment agreement, the Company also paid $2 million during fiscal 
1995 for the development of sub-micron process technology and the fabrication 
of engineering wafers. These agreements call for wafers to be supplied by 
Seiko Epson through S MOS pursuant to a purchase agreement concluded with S 
MOS. As of March 28, 1998, substantially all wafers pursuant to these 
agreements had been received by the Company.

In March 1997, the Company entered into a second advance production payment 
agreement with Seiko Epson and SMOS under which it agreed to advance 
approximately $86 million, payable over two years, to Seiko Epson to 

                                      9

<PAGE>

finance construction of an eight-inch sub-micron semiconductor wafer 
manufacturing facility.  The timing of the payments is related to certain 
milestones in the development of the facility. Under the terms of the 
agreement, the advance is to be repaid with semiconductor wafers over a 
multi-year period. The agreement calls for wafers to be supplied by Seiko 
Epson through S MOS pursuant to purchase agreements concluded with S MOS. The 
Company also has an option under the agreement to advance Seiko Epson an 
additional $60 million for additional wafer supply under similar terms. The 
first payment under this agreement, approximately $17.0 million, was made 
during fiscal 1997. During fiscal 1998, the Company made two additional 
payments aggregating approximately $34.2 million. 

UMC

The Company entered into a series of agreements with UMC in September 1995 
pursuant to which the Company agreed to join UMC and several other companies 
to form a separate Taiwanese company, UICC, for the purpose of building and 
operating an advanced semiconductor manufacturing facility in Taiwan, 
Republic of China. Under the terms of the agreement, the Company invested 
approximately $49.7 million, paid in three installments, for an approximate 
10% equity interest in UICC and the right to receive a percentage of the 
facility's wafer production at market prices. 

In October 1997, the UICC foundry was substantially destroyed by fire. UMC, 
the majority owner of UICC, has informed the Company that this loss is 
insured and has begun the process of rebuilding the foundry. Further, 
alternative capacity arrangements have been made available to the Company by 
UMC. Based on these assurances from UMC, management believes the Company will 
not be materially adversely affected by this event.

AMD

In November 1987, as part of the settlement of a patent infringement suit 
against the Company, the Company and Monolithic Memories Inc. ("MMI", 
subsequently merged with AMD) entered into an agreement cross-licensing each 
other's patents covering programmable and reprogrammable logic devices based 
on patent applications having a first filing date prior to November 1989. The 
agreement was subsequently amended in May 1989 by the Company and AMD, the 
successor to the rights and obligations of MMI in the original agreement. The 
amendment covers those patents relating to PLD products which are based on 
patent applications originally filed by the Company, MMI and AMD prior to 
December 31, 1991. The license, with respect to certain patents asserted by 
AMD, ceases to cover the Company's current principal products if the Company 
is acquired by a semiconductor manufacturer with sales in excess of a stated 
amount or by certain types of companies headquartered in designated Asian 
countries. No license has been granted to either party for any copyright 
work, trademark or process technology and, therefore, AMD has not been 
licensed to use the GAL trademark on its products. 

FACTORS AFFECTING FUTURE RESULTS

The Company believes that its future operating results will be subject to 
quarterly variations based upon a wide variety of factors, including the 
cyclical nature of both the semiconductor industry and the end markets 
addressed by the Company's products, general economic conditions in countries 
where the Company's products are sold, price erosion, timing of new product 
introductions, product obsolescence, scheduling, rescheduling and 
cancellation of large orders, competitive factors, ability to develop and 
implement new process technologies, fluctuations in manufacturing yields, 
ability to achieve volume production at Seiko Epson's and UICC's new 

                                     10

<PAGE>

eight-inch wafer fabs, substantial adverse currency exchange rate movements, 
availability of manufacturing capacity and wafer supply and potential 
litigation expenses. Due to these and other factors, the Company's past 
results are a less useful predictor of future results than is the case in 
more mature and stable industries. The Company has increased its level of 
operating expenses and investment in manufacturing capacity in anticipation 
of future growth in revenues, primarily from increased sales of its ISP 
products. To the extent that this revenue growth does not materialize, the 
Company's operating results would be adversely affected.

The market price of the Company's common stock could be subject to 
significant fluctuations in response to variations in quarterly operating 
results, shortfalls in revenues or earnings from levels expected by 
securities analysts, other factors such as announcements of technological 
innovations or new products by the Company or by the Company's competitors, 
government regulations, developments in patent or other proprietary rights, 
and developments in the Company's relationships with parties to collaborative 
agreements. In addition, the stock market can experience significant price 
fluctuations. These fluctuations often are unrelated to the operating 
performance of the specific companies whose stocks are traded. Broad market 
fluctuations, as well as economic conditions generally and in the 
semiconductor industry specifically, could adversely affect the market price 
of the Company's common stock.

The semiconductor industry is highly cyclical and has been subject to 
significant downturns at various times that have been characterized by 
diminished product demand, production overcapacity and accelerated erosion of 
average selling prices. The Company's rate of growth in recent periods has 
been positively and negatively impacted by trends in the semiconductor 
industry. Any material imbalance in industry-wide production capacity 
relative to demand, shift in industry capacity toward products competitive 
with the Company's products, reduced demand or reduced growth in demand or 
other factors could result in a decline in the demand for or the prices of 
the Company's products and could have a material adverse effect on the 
Company's operating results.

Because of the rapid rate of technological change in the semiconductor 
industry, the Company's success will ultimately depend in large part on its 
ability to introduce new products on a timely basis that meet a market need 
at a competitive price with acceptable margins as well as enhancing the 
performance of its existing products. The success of new products, including 
the Company's ISP product families, depends on a variety of factors, 
including product selection, timely and efficient completion of product 
design, timely and efficient implementation of manufacturing and assembly 
processes, product performance, quality and reliability in the field and 
effective sales and marketing. Because new product development commitments 
must be made well in advance of sales, new product decisions must anticipate 
both future demand and the technology that will be available to supply that 
demand. New and enhanced products are continually being introduced into the 
Company's markets by others, and these products can be expected to affect the 
competitive environment in the markets in which they are introduced. There is 
no assurance that the Company will be successful in enhancing its existing 
products or in selecting, developing, manufacturing, marketing and selling 
new products.

Future revenue growth will be largely dependent on market acceptance of the 
Company's new and proprietary products, including its ISP product families, 
and market acceptance of the Company's proprietary software development 
tools. There can be no assurance that the Company's product and process 
development efforts will be successful or that new products, including the 
Company's ISP products, will continue to achieve market acceptance. If the 
Company were unable to successfully define, develop and introduce competitive 
new products in a timely manner, its future operating results would be 
adversely affected.

                                     11

The semiconductor industry is intensely competitive and is characterized by 
rapid technological change, sudden price fluctuations, general price erosion, 
rapid rates of product obsolescence, periodic shortages of materials and 
manufacturing capacity and variations in manufacturing costs and yields. The 
Company's competitive position is impacted by all of these factors and by 
industry competition for effective sales and distribution channels. The 
Company's existing and potential competitors range from established major 
domestic and international semiconductor companies to emerging companies. 
Many of the Company's competitors have substantially greater financial, 
technological, manufacturing, marketing and sales resources than the Company. 
The Company faces direct competition from companies that have developed or 
licensed similar technology and from licensees of the Company's products and 
technology. The Company also faces indirect competition from a wide variety 
of semiconductor companies offering products and solutions based on 
alternative technologies. Although to date the Company has not experienced 
significant competition from companies located outside the United States, 
such companies may become a more significant competitive factor in the 
future. As the Company and its current competitors seek to expand their 
markets, competition may increase, which could have an adverse effect on the 
Company's operating results. Competitors' development of new technologies 
that have price/performance characteristics superior to the Company's 
technologies could adversely effect the Company's results of operations. 
There can be no assurance that the Company will be able to develop and market 
new products successfully or that the products introduced by others will not 
render the Company's products or technologies non-competitive or obsolete. 
The Company expects that its markets will become more competitive in the 
future.

The future success of the Company is dependent, in part, on its ability to 
attract and retain highly qualified technical and management personnel, 
particularly highly skilled engineers involved in development of new 
products, both silicon and software, and process technology. Competition for 
such personnel is intense. There can be no assurance that the Company will be 
able to retain its existing key technical and management personnel or attract 
additional qualified employees in the future. The loss of key technical or 
management personnel could delay product development cycles or otherwise have 
a material adverse effect on the Company's business.

The Company does not manufacture finished silicon wafers; however, its 
products require wafers manufactured with state-of-the-art fabrication 
equipment and techniques. Accordingly, the Company's strategy has been to 
maintain relationships with large semiconductor manufacturers for the 
production of its wafers. Currently all of its silicon wafers are 
manufactured by either Seiko Epson in Japan or UMC in Taiwan. A significant 
interruption in supply from Seiko Epson, through S MOS, Seiko Epson's 
affiliated U.S. distributor, or from UMC would have a material adverse effect 
on the Company's business.

The Company's finished silicon wafers are assembled and packaged by 
independent subcontractors located in Hong Kong, Malaysia, the Philippines, 
South Korea, Taiwan, and the United States. Although the Company has not yet 
experienced significant problems or interruptions in supply from its assembly 
contractors, any prolonged work stoppages or other failure of these 
contractors to supply finished products could have a material adverse effect 
on the Company's operating results.

International revenues accounted for 48%, 49% and 51% of the Company's 
revenues for fiscal 1996, 1997 and 1998, respectively. The Company believes 
that international revenues will continue to represent a significant 
percentage of revenues. International revenues and operations may be 
adversely affected by regional economic 

                                     12

<PAGE>

conditions, the imposition of governmental controls, export license 
requirements, restrictions on the export of technology, political 
instability, trade restrictions, changes in tariffs and difficulties in 
staffing and managing international operations.

The Company currently depends on foreign manufacturers -- Seiko Epson, a 
Japanese company, and UMC, a Taiwanese company -- for the manufacture of all 
of its finished silicon wafers, and anticipates depending on UICC, a 
Taiwanese company, for the manufacture of a portion of its finished silicon 
wafers. In addition, after wafer manufacturing is completed and each wafer is 
tested, products are assembled by subcontractors in Hong Kong, Malaysia, the 
Philippines, South Korea and Taiwan. Although the Company has yet not 
experienced significant problems or interruption in supply from its 
subcontractors, the social, economic and political situations in these 
countries can be volatile, and any prolonged work stoppages or other 
disruptions in the Company's ability to manufacture and assemble its products 
would have a material adverse effect on the Company's results of operations.  
Furthermore, economic risks, such as recession, exchange rate volatility, 
changes in tax laws, tariffs, or freight rates, or interruptions in air 
transportation, could have a material adverse effect on the Company's results 
of operations.

The Company depends upon wafer suppliers to produce wafers with acceptable 
yields and to deliver them to the Company in a timely manner. Substantially 
all of the Company's revenues are derived from products based on E2CMOS 
process technology. Successful implementation of the Company's proprietary 
E2CMOS process technology, UltraMOS, requires a high degree of coordination 
between the Company and its wafer supplier. Therefore, significant lead time 
is required to reach volume production at a new wafer supply location such as 
Seiko Epson's or UICC's new eight-inch wafer fabs.  Accordingly, there can be 
no assurance that volume production at Seiko Epson's or UICC's new eight-inch 
wafer fabs will be achieved in the near term or at all. The manufacture of 
high performance E2CMOS semiconductor wafers is a complex process that 
requires a high degree of technical skill, state-of-the-art equipment and 
effective cooperation between the wafer supplier and the circuit designer to 
produce acceptable yields. Minute impurities, errors in any step of the 
fabrication process, defects in the masks used to print circuits on a wafer 
and other factors can cause a substantial percentage of wafers to be rejected 
or numerous die on each wafer to be non-functional. As is common in the 
semiconductor industry, the Company has from time to time experienced in the 
past, and expects that it will experience in the future, production yield 
problems and delivery delays. Any prolonged inability to obtain adequate 
yields or deliveries could adversely affect the Company's operating results.

The Company expects that, as is customary in the semiconductor business, it 
will in the future seek to convert its fabrication process technology to 
larger wafer sizes, to smaller device geometries or to new or additional 
suppliers in order to maintain or enhance its competitive position. Such 
conversions entail inherent technological risks that could adversely affect 
yields and delivery times and could have a material adverse impact on the 
Company's operating results. To a considerable extent, the Company's ability 
to execute its strategies will depend upon its ability to maintain and 
enhance its advanced process technologies. As the Company does not presently 
operate its own wafer fabrication or process development facility, the 
Company depends upon silicon wafer manufacturers to provide the facilities 
and support for its process development. In light of this dependency and the 
intensely competitive nature of the semiconductor industry, there is no 
assurance that either process technology development or timely product 
introduction can be sustained in the future.

                                     13

<PAGE>

In addition, other unanticipated changes in or disruptions of the Company's 
wafer supply arrangements could reduce product availability, increase cost or 
impair product quality and reliability. Many of the factors that could result 
in such changes are beyond the Company's control.  For example, a disruption 
of operations at Seiko Epson's or UMC's manufacturing facilities as a result 
of a work stoppage, fire, earthquake or other natural disaster, would cause 
delays in shipments of the Company's products and would have a material 
adverse effect on the Company's operating results.  

The Company's wafer purchases from Seiko Epson are denominated in Japanese 
yen. In the past, the dollar has lost substantial value with respect to the 
yen. There is no assurance that the value of the dollar with respect to the 
yen will not again experience substantial deterioration. Any substantial 
continued deterioration of dollar-yen exchange rates could have a material 
adverse effect on the Company's results of operations.

Worldwide manufacturing capacity for silicon wafers is limited and inelastic. 
Therefore, significant increases in demand or interruptions in supply could 
adversely affect the Company. Through fiscal 1998, the Company has been 
successful in obtaining adequate wafer capacity commitments; however, it has 
in the past experienced delays in obtaining wafers. Although current 
commitments are anticipated to be adequate through fiscal 1999, there can be 
no assurance that existing capacity commitments will be sufficient to permit 
the Company to satisfy all of its customers' demand in future periods. The 
Company negotiates wafer prices and certain wafer supply commitments with 
Seiko Epson, S MOS and UMC on an annual basis, and, in some cases, as 
frequently as semiannually. Moreover, wafer prices and commitments are 
subject to continuing review and revision by the parties. There can be no 
assurance that Seiko Epson, S MOS or UMC will not reduce their allocations of 
wafers or increase prices to the Company in future periods or that any such 
reduction in supply could be offset pursuant to arrangements with alternate 
sources of supply. If any substantial reduction of supply or substantial 
price increase were to occur, the Company's operating results could be 
materially adversely affected.  

In an effort to secure additional wafer supply, the Company may from time to 
time consider various arrangements, including joint ventures, equity 
investments, advanced purchase payments, loans, or similar arrangements with 
independent wafer manufacturers in exchange for committed production 
capacity. Such arrangements have become common within the industry as 
independent wafer manufacturers increasingly seek to require their customers 
to share a portion of the cost of capital intensive wafer fabrication 
facilities.  In 1994, the Company entered into an advanced production payment 
agreement with Seiko Epson pursuant to which it advanced a total of $42 
million to Seiko Epson.  In September 1995, the Company entered into an 
agreement with UMC under which it invested a total of $49.7 million for an 
approximate 10% equity interest in a separate Taiwanese company, UICC.  In 
March 1997, the Company entered into a second advanced production payment 
agreement with Seiko Epson pursuant to which it plans to advance up to $150 
million to Seiko Epson. To the extent the Company pursues any other such 
transactions with Seiko Epson, UMC or any other wafer manufacturers, such 
transactions could entail even greater levels of investment requiring the 
Company to seek additional equity or debt financing to fund such activities. 
There can be no assurance that any such additional funding could be obtained 
when needed or, if available, on terms acceptable to the Company.

The Company's success depends in part on its proprietary technology. While 
the Company attempts to protect its proprietary technology through patents, 
copyrights and trade secrets, it believes that its success will depend more 
upon technological expertise, continued development of new products, and 
successful market penetration of its silicon and software products. There can 
be no assurance that the Company will be able to protect its 

                                     14

<PAGE>

technology or that competitors will not be able to develop similar technology 
independently. The Company currently has a number of United States and 
foreign patents and patent applications. There can be no assurance that the 
claims allowed on any patents held by the Company will be sufficiently broad 
to protect the Company's technology, or that any patents will issue from any 
application pending or filed by the Company. In addition, there can be no 
assurance that any patents issued to the Company will not be challenged, 
invalidated or circumvented or that the rights granted thereunder will 
provide competitive advantages to the Company.

The semiconductor industry is generally characterized by vigorous protection 
and pursuit of intellectual property rights and positions, which have on 
occasion resulted in protracted litigation that utilizes cash and management 
resources, which can have a significant adverse effect on operating results. 
There can be no assurance that  intellectual property claims will not be made 
against the Company in the future or that in the event of such a claim, the 
Company will be able to obtain a license on terms or under conditions that 
would not have a material adverse impact on the Company. 

The Company is currently working to address the potential impact of the Year 
2000 on the processing of date-sensitive information by the Company's 
internal computer systems, including its electronic interfaces to 
distributor, customer and supplier systems.  At present, the Company has 
completed an initial assessment of its potential exposure.  Based on this 
assessment, the Company does not anticipate that resolution of potential 
internal Year 2000 issues will have a material adverse impact on the 
Company's operating results.  However, there can be no assurance that the 
Company's computer systems or the systems of the Company's major 
distributors, suppliers, customers or financial service providers will 
completely address all internal Year 2000 issues in a timely manner.  In the 
event that Year 2000 issues create significant disruption in the operations 
of the Company or any of the Company's major distributors, suppliers, 
customers or financial service providers, the Company's operating results 
could be materially adversely affected.

EMPLOYEES

As of March 28, 1998, the Company had 569 full-time employees. The Company 
believes that its future success will depend, in part, on its ability to 
continue to attract and retain highly skilled technical, marketing and 
management personnel. 

None of the Company's employees is subject to a collective bargaining 
agreement. The Company has never experienced a work stoppage and considers 
its employee relations good. 


ITEM 2.  PROPERTIES

The Company's corporate offices, testing and principal research and design 
facilities are located in two adjacent buildings owned by the Company in 
Hillsboro, Oregon comprising a total of 90,000 square feet. The Company's 
executive, administrative, marketing and production activities are also 
located at these facilities. The Company leases a 41,000 square foot research 
and design facility in Milpitas, California. This lease expires in February, 
2001.

                                     15

</TABLE>

     Executive officers of the Company are appointed by the Board of Directors
to serve at the discretion of the Board and hold office until the officers'
successors are appointed.

     Cyrus Y. Tsui joined the Company in September 1988 as President, Chief
Executive Officer and Director, and in March 1991 was named Chairman of the

Lattice Semiconductor Corporation (which report and consolidated financial 
statements are incorporated by reference in this Annual Report on Form 10-K) 
also included an audit of the Financial Statement Schedule listed in Item

                    NORTH AMERICA SALES REPRESENTATIVE AGREEMENT


     THIS AGREEMENT is entered into in Hillsboro, Oregon, as of 
______________("Effective Date"), between Lattice Semiconductor Corporation, 
a Delaware corporation with principal offices at 5555 N.E. Moore Court, 
Hillsboro, Oregon, 97124 ("Lattice"), and _______, a corporation with 
principal offices at _________ ("Representative").

     IN CONSIDERATION OF THE MUTUAL PROMISES CONTAINED HEREIN, THE PARTIES AGREE
AS FOLLOWS:


1.   DEFINITIONS

     1.1  "Product(s)" means Lattice's hardware and software products 
identified in Lattice's current price list.  Products may be changed, 
reclassified, abandoned or added by Lattice, in its sole discretion.  Lattice 
shall be under no obligation to continue the production or sale of any 
Product.

     1.2  "Territory" shall initially mean those geographical areas set forth 
in Exhibit A attached hereto.  Lattice retains the sole authority and right 
to redefine the Territory at any time and for any or no reason, and to 
resolve as it sees fit any and all conflicts between its sales 
representatives in the event of conflicting, overlapping, or changing 
Territories and Territory boundaries.

2.   APPOINTMENT AND AUTHORITY OF REPRESENTATIVE

     2.1  APPOINTMENT.  Subject to the terms and conditions of this 
Agreement, Lattice hereby appoints Representative as Lattice's exclusive 
sales representative for the Products in the Territory, and Representative 
hereby accepts such appointment.  Representative's sole authority is  to 
solicit orders for the Products in the Territory in accordance with the terms 
of this Agreement.  Representative shall not have the authority to make any 
commitments whatsoever on behalf of Lattice.

     2.2  RESERVED RIGHTS.  Notwithstanding the provisions of Section 2.1 
above, Lattice reserves the right to (a) solicit orders directly from and 
sell Products directly to any customer within the Territory, and (b) 
authorize third party distributors to solicit orders and sell Products in the 
Territory.

     2.3  TERRITORIAL LIMITATION.  Representative shall not advertise, sell 
or solicit orders for the Products from outside the Territory without the 
prior written consent of Lattice.

     2.4  CONFLICT OF INTEREST.  The parties acknowledge that any efforts by 
Representative to  market or sell competing products in the Territory would 
constitute a conflict of interest with respect to Representative's 
obligations to market the Products.  Representative warrants that it does not 
currently represent or sell any Products which compete with Lattice's 
Products.  If Representative 

                                                            Page 1

<PAGE>

intends to market, promote or distribute products that compete with the 
Products, Representative shall notify Lattice of its intent at least sixty 
(60) days prior to commencing such activity and Lattice shall have the right 
at such time and at any time thereafter to immediately terminate this 
Agreement upon written notice to Representative without obligation to pay 
post-termination commissions to Representative as provided for in Section 9 
below. Failure to so notify Lattice will be deemed to be a material breach of 
this Agreement.  A product will be deemed to compete with the Products if, in 
Lattice's sole discretion, such product  provides  substantial overlap of any 
of the functionality or features of the Products.  If Lattice introduces a 
new Product which competes with a product marketed or distributed by 
Representative, Representative will have sixty (60) days to cease 
representing such competing product in order to remain in compliance with 
this provision.

     2.5  INDEPENDENT CONTRACTORS.  The relationship of Lattice and 
Representative established by this Agreement is that of independent 
contractors, and nothing in this Agreement may be construed to (a) give 
either party the power to direct and control the day-to-day activities of the 
other, (b) constitute the parties as partners, joint venturers, co-owners or 
otherwise as participants in a joint undertaking, or (c) allow Representative 
to create or assume any obligation on behalf of Lattice for any propose 
whatsoever.  All financial and other obligations associated with 
Representative's business are the sole responsibility of Representative.  
Representative shall be solely responsible for, and shall indemnify and hold 
Lattice free and harmless from any and all claims, damages or lawsuits 
(including reasonable attorneys' fees) arising out of the willful or 
negligent acts or omissions of Representative, its employees or its agents.

3.   COMPENSATION

     3.1  SOLE COMPENSATION.  Representative's sole compensation under the 
terms of this Agreement shall be commissions computed in accordance with 
commission schedules set by Lattice.  Commission schedules are typically 
revised annually, but may be revised at any time, in Lattice's sole 
discretion.  For convenience of reference only, the initial schedule is set 
forth in Exhibit B.

     3.2  BASIS OF COMMISSION.  The commission shall apply to all Product 
sales shipped to end users in the Territory by Lattice's authorized 
distributors or Lattice.  Commissions shall be computed on the net amount 
received by Lattice from the customer for Products only, and no commission 
shall be paid with respect to charges for handling or freight,  sales taxes, 
COD charges, start-up charges, Product manual charges, qualification or test 
data charges, and the like.  In the case of sales by authorized distributors, 
the basis of the commission will be the cost of the Product paid by the 
authorized distributor, net of all discounts and adjustments.  In the event 
that Lattice, in its sole discretion determines to use the gross amount of 
distributor resales to end customers (or any other measure which exceeds the 
net distributor cost) as the basis for computing commissions, Lattice shall 
have the right at any time on written notice effective immediately to revert 
to the net distributor cost basis of commission as provided herein.  In 
addition, if Lattice does choose to use distributor resale cost as the basis 
for commission, Lattice shall have the right to compute resale cost on any 
basis it deems reasonable, including Lattice's estimate of average 
distributor margins, and to change such method at any time.  With respect to 
software Products, "sales," "cost," and similar terms will be construed as 
"licenses," "sublicenses," "license fees" and other terms used with respect 
to 

                                                            Page 2

<PAGE>

intellectual property transactions as appropriate in context.  For Products 
which are held on  consignment in end-user warehouses, a sale will be 
recognized only when such Products are drawn out of consignment inventory by 
the end user.  The parties may agree, in writing from time to time, on 
adjustments to the regular commission schedule for specific customers, 
Products, or circumstances.

     3.3  TIME OF PAYMENT.  For shipments made directly by Lattice to a 
customer, commissions shall be due and payable thirty (30) days after the end 
of the month in which Lattice invoices the customer for the Products sold in 
the Territory. Commissions on distributor resales to customers shall be due 
and payable thirty (30) days after the end of the month in which Lattice 
receives the distributor's resale information. Commission payments shall be 
subject to all applicable governmental regulations and rulings, including the 
withholding of any taxes required by law.

     3.4  SPLIT COMMISSIONS.  If more than one sales representative is 
involved in the solicitation of a particular order, Lattice, in its sole 
discretion, may split the total commission for the order between or among the 
sales representatives involved.  In no event will the total commission for an 
order exceed the total commission calculated without splitting.  Lattice will 
not make split commission adjustments on any sales more than ninety (90) days 
old, with such ninety (90) day period measured by the time from the shipment 
of the Product  by Lattice to the customer (and the date of receipt of the 
authorized distributor's resale report for distributor's sales) to the date 
of Lattice's approval of the commission split.

     3.5  COMMISSION ADJUSTMENTS.  Lattice shall have the absolute right to 
set such discounts, to make such allowances and adjustments, to accept such 
returns from its customers, and to write off as bad debts such overdue 
customer accounts as it deems advisable.  In each such case, Lattice shall 
have the right to retroactively reduce commissions paid on such revised, 
adjusted, or written off amounts against future commissions payable to 
Representative.  Commissions  with respect to sales to customers who fail to 
pay within sixty (60) days of the invoice date  may in Lattice's sole 
discretion be deducted from current commissions until such customer payments 
are collected.

4.   SALE OF PRODUCTS

     4.1  SOLICITATION OF ORDERS.    Representative shall use its best 
efforts to solicit customer order for the Products.  All inquiries from 
potential customers will be followed up promptly and all prospective orders 
obtained will be promptly forwarded to Lattice for Lattice's response.  All 
orders from end users must show Lattice, rather than Representative, as the 
manufacturer/seller and shall correctly indicate part numbers, 
specifications, quantities, shipping destination and method, desired shipping 
date, and other significant customer data.  Lattice is not required to pay 
commissions on orders which show representative as the manufacturer or 
seller.  Representative shall work closely with customers to ensure proper 
preparation of orders.

     4.2  ACCEPTANCE.  All prospective orders obtained by Representative are 
conditioned on acceptance by Lattice at its principal office currently 
located at the address listed for Lattice at the beginning of this Agreement. 
Representative shall have no authority to make any acceptance or 

                                                            Page 3

<PAGE>

delivery commitments to customers.  Lattice specifically reserves the right 
to reject any order or any part thereof for any reason. 

     4.3  CREDIT APPROVAL.  Lattice shall have the sole right of credit 
approval or credit refusal for customers in all cases.

     4.4  INVOICES.  Lattice shall render all invoices directly to the 
customers and shall send summary reports of commissionable invoices to the 
Representative. Customer payments will be made directly to Lattice.

     4.5  COLLECTION.  It is understood by Representative that responsibility 
for collection of invoices rests with Lattice, and Representative will not 
take any action toward collection of invoices absent express written 
authorization from Lattice.

     4.6  INQUIRIES FROM OUTSIDE THE TERRITORY.  Representative shall 
promptly submit to Lattice, for Lattice's attention and handling, the 
originals of all inquires received by Representative from customers outside 
the Territory.

     4.7  POLICIES.    Representative agrees to abide by Lattice's sales 
policies and procedures as may be  modified by Lattice from time to time, 
including without limitation  those provisions which may limit, delay, or 
restrict payment of commissions in the event of violations of such policies.

5.   PRODUCT WARRANTY AND PRODUCT AVAILABILITY

     5.1  PRODUCT WARRANTY.  Any warranty for the Products shall run directly 
from Lattice to the customer, and pursuant to the warranty the customer shall 
return any allegedly defective Products to Lattice in compliance with 
Lattice's return procedures.   Representative shall have no authority to 
accept any returned Products.  

     LATTICE MAKES AND REPRESENTATIVE RECEIVES NO WARRANTIES OR CONDITIONS OF 
ANY KIND  ON THE PRODUCTS, WHETHER EXPRESS, IMPLIED, STATUTORY, OR IN ANY 
OTHER PROVISION OF THIS AGREEMENT OR COMMUNICATION WITH REPRESENTATIVE, AND 
LATTICE SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTY OF MERCHANTABILITY, 
NONINFRINGEMENT OR FITNESS FOR A PARTICULAR PURPOSE.

     5.2  PRODUCT AVAILABILITY.  Under no circumstances shall Lattice be 
responsible to Representative  in any way for Lattice's failure to fill 
accepted orders, or for its delay in filling accepted orders, regardless of 
the reason therefor.

6.   DEMONSTRATION PRODUCTS

     Lattice may loan certain Products and examples of Product applications 
to Representative as 

                                                            Page 4

<PAGE>

sample or demonstration Products ("Demonstrators").    All such Demonstrators 
will remain the property of Lattice.  All loans of software products shall be 
further subject to the terms and conditions of Lattice's standard software 
license agreement.  Representative shall have full responsibility for keeping 
Demonstrators in proper operating condition during the entire time that the 
Demonstrators are in its possession and Representative shall be responsible 
for any damages to such Demonstrators except for damages or deterioration 
which result from normal wear and tear.  Within fifteen (15) calendar days of 
a written request from Lattice, Representative shall return each Demonstrator 
to Lattice in good condition.

7.   ADDITIONAL RESPONSIBILITIES OF REPRESENTATIVE

     Representative shall have the following responsibilities: 

     (a)  provide sales coverage of OEM accounts and distributor resale 
within the Territory in a competent, professional manner consistent with good 
business practice;

9.   TERM AND TERMINATION

     9.1  TERM.  This Agreement will commence upon the Effective Date and 
continue for a period of one (1) year unless terminated earlier as provided

<PAGE>

          (d)  In the event that Lattice terminates this Agreement for 
convenience, or the Representative terminates this Agreement due to Lattice's 
breach or insolvency, Lattice will pay commissions to the Representative for 
OEM customer Product orders booked before the termination date which are 
shipped through the date of termination.  If the Representative has been a 
sales representative for Lattice for at least two (2) years as of the date of 
termination, then in the event of such termination Lattice will pay 
commissions for OEM customer Product orders booked before the termination 
date which are shipped within thirty (30) days after the date of termination. 
 The thirty (30) days after termination shipment period will be extended an 
additional thirty (30) days  if the Representative has been a sales 
representative for Lattice for at least three (3) years as of the date of 
termination, but in no event will be extended beyond a maximum of sixty (60) 
days after the date of termination.  Lattice will also pay commissions on

remain the property of Lattice, and Representative shall promptly  return or 
destroy, as Lattice may direct, all such materials upon termination of this 
Agreement.

     9.6  LIMITATION OF LIABILITY.  In the event of termination by either 
party in accordance with any of the provisions of this Agreement, neither 
party shall be liable to the other, because of such termination, for 
compensation, reimbursement of expenses, or damages on account of loss of 
prospective profits or anticipated sales or on account of  any other 
expenditures, investments, leases or commitments made in connection with the 
business or goodwill of Lattice or Representative or made in connection with 
this Agreement or the anticipation of extended performance hereunder.  
Lattice's sole liability under the terms of this Agreement shall be for any

     9.7  SURVIVAL OF CERTAIN TERMS.  The provisions of Sections 1, 2.5, 3,

COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY SPECIAL, 
INDIRECT, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT, UNDER ANY 
CAUSE OF ACTION INCLUDING, WITHOUT LIMITATION, THOSE RESULTING FROM THE USE 
OF THE PRODUCTS, OR THE FAILURE OF THE PRODUCTS TO PERFORM, OR FOR ANY OTHER 
REASON.  THESE LIMITATIONS SHALL APPLY WHETHER OR NOT LATTICE HAS BEEN

<PAGE>

REPRESENTS A REASONABLE ALLOCATION OF RISK AND FORMS THE  BASIS FOR THE  
LEVEL OF COMMISSIONS  PAYABLE TO REPRESENTATIVE HEREUNDER.

11.  CONFIDENTIALITY

     Representative acknowledges that by reason of its relationship to 
Lattice hereunder it will have access to certain information and materials 
concerning Lattice's business, plans, customers, technology, and products 
that are confidential and of substantial value to Lattice, which value would 
be impaired if such information were disclosed to third parties. 
Representative agrees that it will not use in any way for its own account or 
the account of any third party, nor disclose to any third party, any such 
confidential information revealed to it by Lattice. Representative shall take 
every reasonable precaution to protect the confidentiality of such 
information.  Upon request by Representative, Lattice shall advise whether or 
not it considers any particular information or materials to be confidential.  
Representative shall not publish any technical description of the Products 
beyond any description which may be published by Lattice.  In the event of 
termination of this Agreement, Representative will no longer use, and will 
not disclose to any third party, any confidential information of Lattice, and 
Representative will not manufacture or have manufactured or sell or 
distribute or represent any products utilizing any of Lattice's confidential 
information.

12.  TRADEMARKS AND TRADE NAMES

     12.1 USE.  During the term of this Agreement, Representative shall have 
the right to indicate to the public that it is an authorized representative 
of Lattice's Products and to advertise within the Territory such Products 
under the trademarks, marks and trade names that Lattice may adopt from time 
to time ("Lattice's Trademarks").  Nothing herein grants Representative any 
right, title or interest in or to Lattice's Trademarks.  At no time during or 
after the term of this Agreement shall Representative challenge or assist 
others to challenge the validity or ownership of Lattice's Trademarks or the 
registration thereof, or attempt to register any trademarks, marks or trade 
names confusingly similar to those of Lattice.

     12.2 APPROVAL OF REPRESENTATIONS.  All representations of Lattice's 
Trademarks that Representative intends to use must first be submitted to 
Lattice for approval (which shall not be unreasonably withheld) of design, 
color, and other details or shall be exact copies of those used by Lattice.  
If any of Lattice's Trademarks are to be used in conjunction with another 
trademark on or in relation to the Products, Lattice's Trademarks shall be 
equally legible, prominent and of equal or greater size than the other but 
nevertheless separated from the other so that each appears to be a mark in 
its own right, distinct from the other mark.

13.  MISCELLANEOUS

     This Agreement constitutes the entire agreement between the parties 
relating to the subject matter hereof and no waiver or modification of this 
Agreement will be valid unless in writing signed 

                                                            Page 8

<PAGE>

by each party. The waiver of a breach of any term hereof will in no way be 
construed as a waiver of any other term or breach hereof.  If any provision 
of this Agreement is held by a court of competent jurisdiction to be contrary 
to law or otherwise unenforceable or of no effect, the remaining provisions 
of this Agreement shall remain in full force and effect.  Lattice shall have 
no liability for its failure to perform its obligations hereunder when due to 
circumstances beyond Lattice's reasonable control.  This Agreement shall 
inure to the benefit of and be binding upon each party's successors and 
assigns.  This Agreement is governed by the laws of the State of Oregon 
without reference to conflict of laws principles.  All disputes arising out 
of this Agreement shall be subject to the exclusive jurisdiction of the state 
and Federal courts located in Multnomah County, Oregon, and the parties agree 
and submit to the personal and exclusive jurisdiction and venue of such 
courts.

     IN WITNESS WHEREOF the parties hereto have executed this Agreement as of
the day and year first above written.

REVENUE Revenue was $245.9 million in fiscal 1998, an increase of 20% over 
fiscal 1997. Fiscal 1997 revenue of $204.1 million represented an increase of 
3% from the $198.2 million recorded in fiscal 1996. The majority of the 
Company's revenue in fiscal 1998 was derived from the sale of products that 
address the ISP segment of the programmable logic market. All of the 
Company's revenue growth for the periods presented resulted from sales of ISP 
products. Revenue from ISP products was approximately 65%, 48% and 28% of 
total revenue for fiscal 1998, 1997 and 1996, respectively.

     Revenue from international sales was approximately 51%, 49% and 48% of 
total revenue for fiscal 1998, 1997 and 1996, respectively. The Company 
expects export sales to continue to represent a significant portion of 
revenue. See "Factors Affecting Future Results."

     Overall average selling prices increased in all three fiscal years 
presented. This was due primarily to a higher proportion of ISP products in 
the revenue mix. Although selling prices of mature products generally decline 
over time, this decline is at times offset by higher selling prices of new 
products. The Company's ability to maintain its recent trend of revenue 
growth is in large part dependent on the continued development, introduction 
and market acceptance of new products.

GROSS MARGIN The Company's gross margin as a percentage of revenue was 60%, 
59% and 59% for fiscal years 1998, 1997 and 1996, respectively. The gross 
margin improvement in fiscal 1998 was primarily due to changes in product mix 
and reductions in the Company's manufacturing costs. Profit margins on older 
products tend to decrease over time as selling prices decline, however the 
Company's strategy has been to offset these decreases by introducing new 
products with higher margins.

RESEARCH AND DEVELOPMENT Research and development expense was $32.0 million, 
$27.8 million and $26.8 million in fiscal 1998, 1997 and 1996, respectively. 
Spending increases were related primarily to the development of new products, 
including the Company's ISP product families and related software development 
tools. The Company believes that a continued commitment to research and 
development is essential in order to maintain a competitive offering in 
existing products and to introduce innovative new products, and therefore 
expects to continue to make significant investments in research and 
development in the future.

SELLING, GENERAL AND ADMINISTRATIVE Selling, general and administrative 
expense was $39.9 million, $33.6 million and $31.3 million in fiscal 1998, 
1997 and 1996, respectively. Spending increases were primarily due to 
expansion of the Company's sales force and increased sales commissions 
associated with higher revenue levels. Selling, general and administrative 
expense as a percentage of revenue was approximately 16% for all fiscal years 
presented.

INCOME FROM OPERATIONS Income from operations increased 27%, from $59.0 
million to $75.1 million, from fiscal 1997 to fiscal 1998, and increased 2%, 
from $57.8 million, between fiscal 1996 and fiscal 1997. Income from 
operations increased as a percentage of revenue, from 29% in fiscal 1996 and 
fiscal 1997 to 31% in fiscal 1998.

INTEREST AND OTHER INCOME Interest and other income (net of expense) 
increased by approximately $1.9 million from fiscal 1997 to fiscal 1998, and 
by approximately $3.3 million from fiscal 1996 to fiscal 1997. The increase 
in both fiscal years was due to higher cash and investment balances resulting 
from the Company's follow-on public offering of common stock in November 
1995, cash generated from operations and common stock issuances from employee 
stock option exercises.

PROVISION FOR INCOME TAXES The Company's effective tax rate was 34.0% for 
fiscal 1998 as compared to 33.5% and 33.9% recorded in fiscal 1997 and 1996, 
respectively. The fiscal 1998 and 1997 rate increase and decrease, 
respectively, was due primarily to variation in the benefit from tax-exempt 
investment income.

Deferred tax asset valuation allowances are recorded to offset deferred tax 
assets that can only be realized by earning taxable income in distant future 
years. Management established the valuation allowances because it cannot 
determine if it is more likely than not that such income will be earned.

NET INCOME Net income increased 26%, from $45.0 million to $56.6 million, 
from fiscal 1997 to fiscal 1998, and increased 8%, from $41.8 million, 
between fiscal 1996 and fiscal 1997. Net income increased as a percentage of 
revenue each fiscal year, from 21% in fiscal 1996 to 22% in fiscal 1997, and 
then to 23% in fiscal 1998.

FACTORS AFFECTING FUTURE RESULTS

Notwithstanding the objectives, projections, estimates and other 
forward-looking statements in this Annual Report, the Company's future 
operating results will continue to be subject to quarterly variations based 
on a wide variety of competitive factors, including, but not limited to, the 
following: timely introduction of new products that meet market needs at 
competitive prices with acceptable margins, market acceptance of the 
Company's new products and proprietary software development tools, 
scheduling, rescheduling and cancellation of large orders, successful 
protection of the Company's intellectual property rights, potential 
litigation relating to competitive patents and intellectual property and the 
Company's ability to attract and retain highly qualified technical and 
management personnel.

     In addition, the Company's operating results are subject to variations 
based upon the following factors: the Company's continued ability to obtain 
adequate wafer capacity supply commitments under competitive pricing terms, 
successful development and implementation of future new advanced process 
technologies at its wafer manufacturers, attainment of acceptable wafer 
manufacturing yields, the ability to achieve volume production at Seiko 
Epson's and UICC's new eight-inch wafer fabs, and potential interruptions in 
supply from the Company's wafer manufacturers and assembly contractors as a 
result of work stoppages, political instability or natural or man-made 
disasters.

     The Company's operating results also depend in large part on various 
factors outside the Company's control such as general economic conditions and 
specific conditions in countries where the Company's products are sold, the 
cyclical nature of both the semiconductor industry and the end markets served 
by the Company's products, sudden price fluctuations, general price erosion 
and substantial adverse currency change movements. The semiconductor industry 
is highly cyclical and has been subject to significant downturns at various 
times that have been characterized by diminished product demand, production 
overcapacity and accelerated erosion of average selling prices. The Company's 
rate of growth in recent periods has been positively and negatively impacted 
by trends in the semiconductor industry. Any material imbalance in 
industry-wide production capacity relative to demand, shift in industry 
capacity toward products competitive with the Company's products, reduced 
demand, reduced growth in demand or other factors could result in a decline 
in the demand for or the prices of the Company's products and have a material 
adverse effect on the Company's operating results. The Company's operating 
results are also dependent upon international revenues which may be adversely 
affected by the imposition of government controls, export license 
requirements, trade restrictions, financial and political instability, 
changes in tariffs and other factors outside the Company's control.

     Due to these and other factors, the Company's past results are a less 
useful predictor of future results than is the case in more mature and stable 
industries. The market price of the Company's common stock could be subject 
to significant fluctuations due to the inherent volatility of the 
semiconductor industry combined with the aforementioned or other factors, 
including variations in the Company's quarterly operating results and 
shortfalls in revenues or earnings from levels expected by securities 
analysts. In addition, the stock market can experience significant price 
fluctuations, which often are unrelated to the operating performance of the 
specific companies whose stocks are traded. Broad market fluctuations, as 
well as economic conditions generally and in the semiconductor industry 
specifically, may adversely affect the market price of the Company's common 
stock.

     The Company is currently working to address the potential impact of the 
Year 2000 on the processing of date-sensitive information by the Company's 
internal computer systems, including its electronic interfaces to 
distributor, customer and supplier systems. At present, the Company has 
completed an initial assessment of its potential exposure. Based on this 
assessment, the Company does not anticipate that resolution of potential 
internal Year 2000 issues will have a material adverse impact on the 
Company's operating results. However, there can be no assurance that the 
Company's computer systems or the systems of the company's major 
distributors, suppliers, customers or financial service providers will 
completely address all Year 2000 issues in a timely manner. In the event that 
Year 2000 issues create significant disruption in the operations of the 
Company or any of the Company's major distributors, suppliers, customers or 
financial service providers, the Company's operating results could be 
materially adversely affected.

     For further explanation of the factors set forth above, see "Factors 
Affecting Future Results" in Item 1 of the Company's Annual Report on Form 
10-K for the fiscal year ended March 28, 1998.

LIQUIDITY AND CAPITAL RESOURCES

As of March 28, 1998, the Company's principal source of liquidity was $267.1 
million of cash and short-term investments, an increase of $38.5 million from 
the balance of $228.6 million at March 29, 1997. This increase was primarily 
the result of cash generated from operations and common stock issuances in 
excess of cash required for foundry investments and wafer supply advances 
made in fiscal 1998. The Company also has available an unsecured $10 million 
demand bank credit facility with interest due on outstanding balances at a 
money market rate. This facility has not been used.

     Accounts receivable and deferred income on sales to distributors 
increased $2.3 million and $2.5 million, or 9% and 14%, respectively, as 
compared to the balances at March 29, 1997. These increases were primarily 
due to higher revenue levels in the fiscal 1998 fourth quarter and the timing 
of billings to end customers and distributors. Inventories decreased by $5.2 
million, or 19%, versus amounts recorded at March 29, 1997 in response to 
shorter lead time of supply, availability of manufacturing capacity and 
anticipated customer requirements. Prepaid expenses and other current assets 
decreased by $10.9 million, or 66%, as compared to the balance at March 29, 
1997 due primarily to a decrease in the current portion of wafer supply 
advances. The $48.9 million increase in Foundry investments, advances and 
other assets resulted primarily from the payment of approximately $34.2 
million to Seiko Epson in fiscal 1998 pursuant to an advance payment purchase 
agreement. Additionally, in fiscal 1998 the Company paid approximately $10.2 
million, the last of three planned payments, to fund the Company's investment 
in United Integrated Circuits Corporation ("UICC"). See below and note 4 of 
notes to consolidated financial statements. Accounts payable and other 
accrued expenses increased by $3.9 million, or 27%, due primarily to 
increased cash payments for wafers. Accrued payroll obligations increased 
$1.6 million, or 16%, as compared to the balance at March 29, 1997 due to 
increased headcount and timing of payments. Income taxes payable increased 
$3.4 million, or 438%, as compared to the balance at March 29, 1997 due to 
the timing of tax deductions and payments.

     Stockholders' equity increased by approximately $74.2 million, primarily 
due to net income of approximately $56.6 million for fiscal 1998 and net 
proceeds from common stock issuances.

     Capital expenditures were approximately $18.8 million, $10.6 million and 
$12.6 million for fiscal years 1998, 1997 and 1996, respectively. These 
expenditures consisted primarily of manufacturing test equipment, engineering 
equipment, buildings and building improvements. The increase in fiscal 1998 
capital expenditures as compared to fiscal 1997 and 1996 was associated with 
construction in progress of additional corporate facilities and increased 
investment in manufacturing test equipment to support the growth in revenue 
from ISP products.

     The Company currently anticipates capital expenditures of approximately 
$20 million to $25 million for the fiscal year ending April 3, 1999.

     The majority of the Company's silicon wafer purchases are denominated in 
Japanese yen. The Company maintains yen-denominated bank accounts and bills 
its Japanese customers in yen. The yen bank deposits are utilized to hedge 
yen-denominated wafer purchases and are accounted for as identifiable hedges 
against specific and firm wafer purchases.

     The Company entered into a series of agreements with United 
Microelectronics Corporation ("UMC") in September 1995 pursuant to which the 
Company agreed to join UMC and several other companies to form a separate 
Taiwanese Company, UICC, for the purpose of building and operating an 
advanced semiconductor manufacturing facility in Taiwan, Republic of China. 
Under the terms of the agreements, the Company invested approximately $49.7 
million, for an approximate 10% equity interest in UICC and the right to 
receive a percentage of the facility's wafer production at market prices.

     In March 1997, the Company entered into an advance payment production 
agreement with Seiko Epson Corporation ("Seiko Epson") and its affiliated 
U.S. distributor, S MOS Systems Inc. ("S MOS") under which it agreed to 
advance approximately $86 million, payable over two years, to Seiko Epson to 
finance construction of an eight-inch sub-micron semiconductor wafer 
manufacturing facility. Under the terms of the agreement, the advance is to 
be repaid with semiconductor wafers over a multi-year period. The agreement 
calls for wafers to be supplied by Seiko Epson through S MOS pursuant to 
purchase agreements with S MOS. The Company also has an option under this 
agreement to advance Seiko Epson an additional $60 million for additional 
wafer supply under similar terms. The first payment pursuant to this 
agreement, approximately $17.0 million, was made during March 1997. During 
fiscal 1998, the Company made two additional payments aggregating 
approximately $34.2 million. As a result of future payments to Seiko Epson, 
the Company's working capital will be reduced by approximately $35 million 
during fiscal 1999.

     On June 12, 1998, the Company's Board of Directors authorized management 
to repurchase up to 1.2 million shares of the Company's common stock. As of 
June 16, 1998, the Company had not repurchased any shares.

     The Company believes that its existing sources of liquidity and expected 
cash generated from operations will be adequate to fund the Company's 
anticipated cash needs for the next fiscal year.

     In an effort to secure additional wafer supply, the Company may from 
time to time consider various financial arrangements including joint 
ventures, equity investments, advance purchase payments, loans, or similar 
arrangements with independent wafer manufacturers in exchange for committed 
wafer capacity. To the extent that the Company pursues any such additional 
financial arrangements, additional debt or equity financing may be required. 
There can be no assurance that any such additional funding could be obtained 
when needed or, if available, on terms acceptable to the Company.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- ------------------------------------------------------------------------------

NOTE 1. NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:

NATURE OF OPERATIONS Lattice Semiconductor Corporation (the "Company") 
designs, develops and markets high performance programmable logic devices 
("PLDs") and related development system software. The Company is the inventor 
and world's leading supplier of in-system programmable ("ISP(TM)") logic 
devices. PLDs are standard semiconductor components that can be configured by 
the end customer as specific logic functions, enabling shorter design cycle 
times and reduced development costs. The Company's end customers are 
primarily original equipment manufacturers ("OEMs") of communications, 
computing, industrial controls and military systems. Approximately one-half 
of the Company's revenue is derived from international sales, mainly in 
Europe and Asia. The Company was founded in 1983 and is based in Hillsboro, 
Oregon.

FISCAL REPORTING PERIOD AND PRINCIPLES OF CONSOLIDATION The Company reports 
on a 52 or 53 week fiscal year, which ends on the Saturday closest to March 
31. The accompanying consolidated financial statements include the accounts 
of Lattice Semiconductor Corporation and its wholly-owned foreign 
subsidiaries, Lattice GmbH, Lattice Semiconducteurs SARL, Lattice 
Semiconductor KK, Lattice Semiconductor Shanghai Co., Ltd., Lattice 
Semiconductor Asia Ltd., Lattice Semiconductor International Ltd., Lattice 
Semiconductor UK Ltd. and Lattice Semiconductor AB. The assets, liabilities, 
and results of operations of these entities were not material for any of the 
years presented in the consolidated financial statements and all intercompany 
accounts and transactions have been eliminated.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS The Company considers all highly 
liquid investments, which are readily convertible into cash and have original 
maturities of three months or less, to be cash equivalents. Short-term 
investments, which have maturities greater than three months and less than 
one year, are composed of money market preferred stocks ($110.2 million), 
government obligations ($70.2 million), commercial paper ($6.9 million) and 
time deposits ($19.5 million) at March 28, 1998.

     The Company categorizes its short-term investments as held-to-maturity, 
which are stated at amortized cost with corresponding premiums or discounts 
amortized over the life of the investment to interest income. Amortized cost 
approximates market value at March 28, 1998.

FINANCIAL INSTRUMENTS All of the Company's significant financial assets and 
liabilities are recognized in the Consolidated Balance Sheet as of March 28, 
1998 and March 29, 1997. The carrying value of the Company's financial 
instruments approximate current market value except foundry equity 
investments in Taiwan which are either not readily marketable or where market 
prices are not necessarily indicative of realizable value. The Company 
estimates the fair value of its cash and cash equivalents, short-term 
investments, accounts receivable, other current assets and current 
liabilities based upon existing interest rates related to such assets and 
liabilities compared to the current market rates of interest for instruments 
of similar nature and degree of risk.

DERIVATIVE FINANCIAL INSTRUMENTS In order to minimize exposure to foreign 
exchange risk with respect to its long-term investments made with foreign 
currencies as further described in note 4 of notes to consolidated financial 
statements, the Company has at times entered into foreign forward exchange 
contracts in order to hedge these transactions. These contracts are accounted 
for as identifiable hedges against firm Company commitments. Realized gain or 
loss with respect to these contracts for the fiscal periods presented was not 
material. As of March 28, 1998, the Company had no open foreign exchange 
contracts for the purchase or sale of foreign currencies. The Company does 
not enter into derivative financial instruments for trading purposes.

FOREIGN EXCHANGE The majority of the Company's silicon wafer purchases are 
denominated in Japanese yen. The Company maintains yen-denominated bank 
accounts and bills its Japanese customers in yen. The yen bank deposits are 
utilized to hedge yen-denominated wafer purchases and are accounted for as 
identifiable hedges against specific and firm wafer purchases. Gains or 
losses from foreign exchange rate fluctuations on unhedged balances 
denominated in foreign currencies are reflected in Other income. Realized and 
unrealized gains or losses were not significant for the fiscal periods 
presented.

CONCENTRATIONS OF CREDIT RISK Financial instruments which potentially expose 
the Company to concentrations of credit risk consist primarily of short-term 
investments and trade receivables. The Company places its investments through 
several financial institutions and mitigates

                                      16


LATTICE SEMICONDUCTOR CORPORATION
<PAGE>

the concentration of credit risk by placing percentage limits on the maximum 
portion of the investment portfolio which may be invested in any one 
investment instrument. Investments consist primarily of A1 and P1 or better 
rated U.S. commercial paper, U.S. government agency obligations and other 
money market instruments, "AA" or better rated municipal obligations, money 
market preferred stocks and other time deposits. Concentrations of credit 
risk with respect to trade receivables are mitigated by a geographically 
diverse customer base and the Company's credit and collection process. The 
Company performs credit evaluations for all customers and secures 
transactions with letters of credit or advance payments where necessary. 
Write-offs for uncollected trade receivables have not been significant to 
date.

REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE Revenue from sales to OEM 
customers is recognized upon shipment. Certain of the Company's sales are 
made to distributors under agreements providing price protection and right of 
return on unsold merchandise. Revenue and cost relating to such distributor 
sales are deferred until the product is sold by the distributor and related 
revenue and costs are then reflected in income. Accounts receivable are shown 
net of allowance for doubtful accounts of $797,000 and $874,000 at March 28, 
1998 and March 29, 1997, respectively.

No individual customer or distributor accounted for more than 10% of revenue 
in fiscal 1998 or 1997. Revenue from one distributor was $21.1 million for 
fiscal 1996. Export revenue was approximately $125.6 million, $99.8 million 
and $95.1 million for fiscal 1998, 1997 and 1996, respectively. Sales to 
Europe were approximately $61.2 million, $39.9 million and $37.9 million, and 
to Asia $55.9 million, $52.6 million and $52.4 million in fiscal 1998, 1997 
and 1996, respectively.

INVENTORIES Inventories are stated at the lower of first-in, first-out cost 
or market.

LONG-LIVED ASSETS During the fiscal year ended March 29, 1997, the Company 
adopted 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. The adoption of SFAS 
121 did not have a material impact on the Company's financial condition or 
results of operations.

PROPERTY AND EQUIPMENT Property and equipment are stated at cost. 
Depreciation is computed using the straight-line method for financial 
reporting purposes over the estimated useful lives of the related assets, 
generally three to five years for equipment and thirty years for buildings. 
Accelerated methods of computing depreciation are generally used for income 
tax purposes.

TRANSLATION OF FOREIGN CURRENCIES The Company translates accounts denominated 
in foreign currencies in accordance with SFAS 52, "Foreign Currency 
Translation." Translation adjustments related to the consolidation of foreign 
subsidiary financial statements have not been significant to date.

RESEARCH AND DEVELOPMENT Research and development costs are expensed as 
incurred.

STOCK-BASED COMPENSATION The Company accounts for its employee and director 
stock options and employee stock purchase plan in accordance with provisions 
of Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting for 
Stock Issued to Employees." During 1995, the Financial Accounting Standards 
Board ("FASB") issued SFAS 123, "Accounting for Stock-Based Compensation." 
SFAS 123, effective for fiscal years beginning after December 31, 1995, 
provides an alternative to APB 25, but allows companies to account for 
employee and director stock-based compensation under the current intrinsic 
value method as prescribed by APB 25. The Company has continued to account 
for its employee and director stock plans in accordance with APB 25. 
Additional pro forma disclosures as required under SFAS 123 are presented in 
note 8 of notes to consolidated financial statements.

NET INCOME PER SHARE Net income per share is computed based on the weighted 
average number of shares of common stock and common stock equivalents assumed 
to be outstanding during the period (using the treasury stock method). Common 
stock equivalents consist of stock options and warrants to purchase common 
stock. All share and per share amounts presented in the accompanying 
consolidated financial statements and notes thereto have been adjusted to 
reflect the three-for-two stock split effected in the form of a stock 
dividend which was paid on July 6, 1993.

                                      17

     In February 1997, the FASB issued SFAS 128, "Earnings Per Share," which 
is effective for the Company for periods ending after December 15, 1997. 
Accordingly, the Company adopted this pronouncement in the quarter ended 
December 27, 1997. Primary net income per share as previously reported has 
been replaced by "basic net income per share" and "diluted net income per 
share." Prior period results have been restated to conform to the new 
presentation.

     The most significant difference between basic and diluted net income per 
share is that basic net income per share does not treat potentially dilutive 
securities such as options and warrants as outstanding. For the Company, 
there is no difference between diluted net income per share and primary net 
income per share as previously reported. A reconciliation of the numerators 
and denominators of basic and diluted net income per share is presented below:

</TABLE>

STATEMENT OF CASH FLOWS Income taxes paid approximated $23.1 million, $22.6 
million and $17.3 million in fiscal 1998, 1997, and 1996, respectively. 
Interest paid does not differ materially from interest expense, which 
aggregated approximately $83,000, $152,000 and $42,000 in fiscal 1998, 1997 
and 1996, respectively.

USE OF 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 fiscal periods presented. Actual results could differ from those 
estimates.

NEW ACCOUNTING PRONOUNCEMENTS In June 1997, the FASB issued SFAS 130, 
"Reporting Comprehensive Net Income." Under SFAS 130, the Company is required 
to report comprehensive income and its components in its consolidated 
financial statements, in addition to net income.

     Also in June 1997, the FASB issued SFAS 131, "Disclosures About Segments 
of an Enterprise and Related Information." This pronouncement establishes 
standards for the way companies report information about operating segments 
for the fiscal years beginning after December 15, 1997. It also establishes 
standards for related disclosures about products and services, geographic 
areas and major customers.

     The Company will adopt these two new pronouncements in the fiscal year 
ending April 3, 1999. It is expected that adoption will not have a 
significant impact on the consolidated financial statements.

The Company entered into a series of agreements with United Microelectronics 
Corporation ("UMC") in September 1995 pursuant to which the Company has 
agreed to join UMC and several other companies to form a separate Taiwanese 
corporation ("UICC") for the

                                      18

<PAGE>

purpose of building and operating an advanced semiconductor manufacturing 
facility in Taiwan, Republic of China. Under the terms of the agreements, the 
Company invested approximately $49.7 million, paid in three installments, for 
an approximate 10% equity interest in the corporation and the right to 
receive a percentage of the facility's wafer production at market prices. 
This investment is accounted for at cost. The first payment, in the amount of 
approximately $13.7 million, was paid in January 1996, the second payment, in 
the amount of approximately $25.8 million, was paid during January 1997, and 
the final payment of approximately $10.2 million was made in December 1997.

     In October 1997, the UICC foundry was substantially destroyed by fire. 
UMC, the majority owner of UICC, has informed the Company that this loss is 
insured and has begun the process of rebuilding the foundry. Further, 
alternative capacity arrangements have been made available to the Company. 
Based on these assurances from UMC, management believes the Company will not 
be materially adversely affected by this event.

     In July 1994, the Company signed an agreement with Seiko Epson 
Corporation ("Seiko Epson") and its affiliated U.S. distributor, S MOS 
Systems Inc. ("S MOS"), under which it advanced $44 million to be used to 
finance additional sub-micron wafer manufacturing capacity and technological 
development. The advance is being repaid in the form of semiconductor wafers 
over a multi-year period. No interest income is recorded. Total wafer 
receipts under this agreement aggregated approximately $15,425,000, 
$18,042,000 and $10,713,000 during fiscal 1998, 1997 and 1996, respectively.

     In March 1997, the Company entered into a second advance payment 
production agreement with Seiko Epson and S MOS under which it agreed to 
advance approximately $86 million, payable over two years, to Seiko Epson to 
finance construction of an eight-inch sub-micron semiconductor wafer 
manufacturing facility. Under the terms of the agreement, the advance is to 
be repaid with semiconductor wafers over a multi-year period. No interest 
income is recorded. The agreement calls for wafers to be supplied by Seiko 
Epson through S MOS pursuant to purchase agreements with S MOS. The Company 
also has an option under the agreement to advance Seiko Epson an additional 
$60 million for additional wafer supply under similar terms. The first 
payment under this agreement, approximately $17.0 million, was made during 
fiscal 1997. During fiscal 1998, the Company made two additional payments 
aggregating approximately $34.2 million.

NOTE 5. CREDIT FACILITIES

The Company has available an unsecured $10 million demand bank credit 
facility with interest due on outstanding balances at a money market rate. 
This facility has not been used.

NOTE 6. LEASE OBLIGATIONS

Certain facilities and equipment of the Company are leased under operating 
leases, which expire at various times through fiscal 2001. Rental expense 
under the operating leases was approximately $1,026,000, $984,000 and 
$993,000 for fiscal 1998, 1997 and 1996, respectively. Future minimum lease 
commitments at March 28, 1998 are as follows:

The valuation allowances are recorded to reduce deferred tax assets which can 
only be realized by earning taxable income in distant future years. 
Management established the valuation allowances because it cannot determine 
if it is more likely than not that such income will be earned.

NOTE 8. STOCKHOLDERS' EQUITY

COMMON STOCK In November 1995, the Company completed its third public 
offering, consisting of 2,500,000 shares of common stock at $36.63 per share. 
Net proceeds to the Company were approximately $86.7 million after 
underwriting discount and offering expenses.

STOCK WARRANTS As of March 28, 1998, the Company has issued to a vendor 
warrants to purchase 583,094 shares of common stock. Of this amount, 464,125 
warrants were issued and 340,500 exercised prior to fiscal 1996. During 
fiscal 1997, 67,419 warrants were issued and none were exercised. During 
fiscal 1998, a warrant was issued to purchase 51,550 shares of common stock, 
earned ratably from March 1997 through February 1998. Additionally, the 
vendor exercised warrants for 123,625 shares at an average exercise price of 
$18.77 per share.

STOCK OPTION PLANS As of March 28, 1998, the Company had reserved 2,000,000 
and 5,775,000 shares of common stock for issuance to officers and key 
employees under the 1996 Stock Incentive Plan and 1988 Stock Incentive Plan, 
respectively. The 1996 Plan options generally vest over four years in 
increments as determined by the Board of Directors and have terms up to ten 
years. The 1988 Plan options are exercisable immediately and have terms up to 
ten years. The transfer of certain shares of common stock acquired through 
the exercise of 1988 Plan stock options is restricted under stock vesting 
agreements that grant the Company the right to repurchase unvested shares at 
the exercise price if employment is terminated. Generally, the Company's 
repurchase rights lapse quarterly over four years.

     The 1993 Directors' Stock Option Plan provides for the issuance of stock 
options to members of the Company's Board of Directors who are not employees 
of the Company; 225,000 shares of the Company's Common Stock have been 
reserved for issuance thereunder. These options are granted at fair market 
value at the date of grant and generally become exercisable quarterly over a 
four year period beginning on the date of grant and expire five years from 
the date of grant.

STOCK PURCHASE PLAN The Company's employee stock purchase plan was approved 
by the stockholders in August 1990, and became effective January 1, 1991. The 
plan permits eligible employees to purchase shares of common stock through 
payroll deductions, not to exceed 10% of the employee's compensation. The 
purchase price of the shares is the lower of 85% of the fair market value of 
the stock at the beginning of each six-month period or 85% of the fair market 
value at the end of such period, but in no event less than the book value per 
share at the mid-point of each offering period. Amounts accumulated through 
payroll deductions during the offering period are used to purchase shares on 
the last day of the offering period. Of the 700,000 shares authorized to be 
issued under the plan, 34,945, 57,421 and 54,239 shares were issued during 
fiscal 1998, 1997 and 1996, respectively, and 272,864 shares were available 
for issuance at March 28, 1998.

PRO FORMA DISCLOSURES The Company accounts for its stock options and employee 
stock purchase plan in conformity with APB 25 and has adopted the additional 
proforma disclosure provisions of SFAS 123. 

     The fair value, as defined by SFAS 123, for stock options and employee 
stock plan purchase rights was estimated on the date of grant using the 
Black-Scholes option pricing model with the following assumptions:

The Black-Scholes option pricing model was developed for use in estimating 
the fair value of freely tradable, fully transferable options without vesting 
restrictions. The Company's stock options have characteristics which 
significantly differ from those of freely tradable, fully transferable 
options. The Black-Scholes option pricing model also requires highly 
subjective assumptions, including expected stock price volatility and 
expected stock option term which greatly affect the calculated fair value of 
an option. The Company's actual stock price volatility and option term may be 
materially different from the assumptions used herein.

     The resultant grant date weighted-average fair values calculated using 
the Black-Scholes option pricing model and the noted assumptions for stock 
options granted was $25.20, $11.54 and $12.44, and for stock purchase rights 
$12.30, $6.80 and $5.49, for fiscal 1998, 1997 and 1996, respectively.

     For purposes of pro forma disclosures, the estimated fair value of the 
options is amortized to expense over the options' vesting period. The 
Company's pro forma information is as follows:

Because the SFAS 123 pro forma disclosure applies only to options granted 
subsequent to April 1, 1995, its pro forma effect will not be fully reflected 
until subsequent years. The effects on pro forma disclosures of applying SFAS 
123 are not likely to be representative of the effects on pro forma 
disclosures in future years.

SHAREHOLDER RIGHTS PLAN A shareholder rights plan approved on September 11, 
1991 provides for the issuance of one right for each share of outstanding 
common stock. With certain exceptions, the rights will become exercisable 
only in the event that an acquiring party accumulates beneficial ownership of 
20% or more of the Company's outstanding common stock or announces a tender 
or exchange offer, the consummation of which would result in ownership by 
that party of 20% or more of the Company's outstanding common stock. The 
rights expire on September 11, 2001 if not previously redeemed or exercised. 
Each right entitles the holder to purchase, for $60.00, a fraction of a share 
of the Company's Series A Participating Preferred Stock with economic terms 
similar to that of one share of the Company's common stock. The Company will 
generally be entitled to redeem the rights at $0.01 per right at any time on 
or prior to the tenth day after an acquiring person has acquired beneficial 
ownership of 20% or more of the Company's common stock. If, prior to the 
redemption or expiration of the rights, an acquiring person or group acquires 
beneficial ownership of 20% or more of the Company's outstanding common 
stock, each right not beneficially owned by the acquiring person or group 
will entitle its holder to purchase, at the rights' then current exercise 
price, that number of shares of common stock having a value equal to two 
times the exercise price.

NOTE 9. TRANSACTIONS WITH PRINCIPAL SUPPLIERS

The majority of the Company's silicon wafers are currently manufactured by 
Seiko Epson in Japan and are sold to the Company through Seiko Epson's 
affiliated U.S. distributor, S MOS. The Chairman of the Board of S MOS is a 
member of the Company's Board of Directors. The Company also receives wafers 
in connection with the series of agreements entered into with UMC as 
described in note 4 of notes to consolidated financial statements. A 
significant interruption in supply from Seiko Epson through S MOS, or from 
UMC, would have a material adverse effect on the Company's business.

     The Company has signed two advance payment production agreements with 
Seiko Epson and S MOS, in July 1994 and March 1997, respectively, under which 
it has advanced or will advance cash to be used in conjunction with the 
construction of additional wafer capacity, with the advances being repaid in 
the form of semiconductor wafers over a multi-year period. These transactions 
are more fully described in note 4 of notes to consolidated financial 
statements.

     The Company continues to purchase a portion of its wafer supply from 
Seiko Epson for cash using commercial terms. Wafer purchases totaled $20.9 
million, $22.8 million and $34.7 million for fiscal 1998, 1997 and 1996, 
respectively. Accounts payable and accrued expenses at March 28, 1998 and 
March 29, 1997 include $4.5 and $1.9 million, respectively, due this vendor. 
Open purchase commitments to this vendor approximated $6.8 million at March 
28, 1998.

NOTE 10. EMPLOYEE BENEFIT PLANS

Profit Sharing Plan The Company initiated a profit sharing plan effective 
April 1, 1990. Under the provisions of this plan, as approved by the Board of 
Directors, a percentage of the operating income of the Company, as defined 
and calculated at the end of the second and fourth quarter of each fiscal 
year for each respective six-month period, is paid equally to qualified 
employees. In fiscal 1998, 1997 and 1996, approximately $3.0 million, $2.4 
million and $2.3 million, respectively, were charged against operations in 
connection with the plan.

QUALIFIED INVESTMENT PLAN In 1990, the Company adopted a 401(k) plan, which 
provides participants with an opportunity to accumulate funds for retirement. 
Under the terms of the plan, eligible participants may contribute up to 15% 
of their eligible earnings to the plan Trust. The plan allows for 
discretionary matching contributions by the Company; no such contributions 
occurred through fiscal 1996. Beginning in fiscal 1997, the Company matched 
eligible employee contributions of up to 5% of base pay. Company 
contributions are discretionary and vest over four years.

NOTE 11. COMMITMENTS AND CONTINGENCIES

The Company is exposed to certain asserted and unasserted potential claims. 
Patent and other proprietary rights infringement claims are common in the 
semiconductor industry. There can be no assurance that, with respect to any 
such claims made against the Company, the Company could obtain a license on 
terms or under conditions that would not have a material adverse effect on 
the Company.

NOTE 12. RELATED PARTY

Larry W. Sonsini is a member of the Company's Board of Directors and is 
presently the Chairman of the Executive Committee of Wilson, Sonsini, 
Goodrich & Rosati, a law firm that provides corporate legal services to the 
Company. Legal services billed to the Company aggregated approximately 
$51,000, $61,000 and $177,000, respectively, for fiscal 1998, 1997 and 1996. 
Amounts payable to the law firm were not significant at March 28, 1998 or 
March 29, 1997.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Lattice Semiconductor 
Corporation

In our opinion, the accompanying consolidated balance sheet and the related 
consolidated statements of operations, of changes in stockholders' equity and 
of cash flows present fairly, in all material respects, the financial 
position of Lattice Semiconductor Corporation and its subsidiaries at March 
28, 1998 and March 29, 1997, and the results of their operations and their 
cash flows for each of the three years in the period ended March 28, 1998, in 
conformity with generally accepted accounting principles. 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 
generally accepted auditing standards 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.
