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 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 Dataquest 
Incorporated, a semiconductor market research firm, logic accounted for 
approximately 31% of the estimated $103 billion worldwide digital integrated 
circuit market in 1996. 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. Logic is often classified by the number of 
gates per chip, with PLDs offering up to 50,000 gates, and conventional gate 
arrays and custom logic circuits reaching up to several hundred thousand 
gates. 

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


                                       2


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 sacraficing 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 
programming.  A recent development pioneered by the Company, in-system 
programmable PLDs, extends 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 types of PLDs currently coexist in the marketplace, each 
offering customers a particular set of benefits. These include low-density 
PLDs (less than 1,000 gates) and high-density PLDs (greater than 1,000 
gates). High-density PLDs include both complex PLDs ("CPLDs," up to 25,000 
gates) and field programmable gate arrays ("FPGAs," up to 50,000 gates). 

Low-density devices are typically based on industry standard architectures 
and include the GAL-Registered Trademark- ("Generic Array Logic") product 
family developed by the Company. These architectures are familiar to most 
system designers and are supported by standard widely available development 
tools. Offering the highest absolute performance and lowest cost per device, 
these products are the most effective PLD solution to support simple logic 
functions. 

High-density devices are typically based on proprietary architectures and 
require support from sophisticated computer aided engineering ("CAE") 
development tools.  Due to higher levels of logic integration, absolute 
performance typically lags that of state-of-the-art low-density PLDs by one 
or more technology generations. However, in situations requiring complex 
logic functions, high-density PLDs can provide important advantages over
a large cluster of low-density devices. These advantages include system 
performance enhancement and power and cost savings. 

CPLDs and FPGAs are the two primary types of high-density PLD architectures. 
Each architecture is generally optimal for different types of logic 
functions, although many logic functions can be implemented with either 
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 ("E(2)CMOS-Registered 
Trademark-") is the preferred process technology for both high-density CPLDs 
and low-density PLDs due to its inherent performance, reprogrammability and 
testability benefits. E(2)CMOS, through its fundamental ability to be 
programmed and erased electronically, serves as the foundation for the 
Company's ISP products. 


                                       3


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 
high-density CPLD 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 E(2)CMOS programmable logic devices require 
12-volt electrical signals 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. All of the Company's 
high-density CPLDs are available with ISP. The Company also offers its most 
popular low-density architecture, the GAL22V10, with ISP. 

E(2)CMOS PROCESS TECHNOLOGY

The Company's current high- and low-density PLD offerings are based on the 
Company's proprietary E(2)CMOS 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.

In comparison to bipolar technology, at one time the dominant technology for 
low-density PLDs, E(2)CMOS technology consumes less power and generates less 
heat while operating at comparable speed. Additionally, in contrast to 
one-time-programmable bipolar PLDs, E(2)CMOS 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 E(2)CMOS, 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 E(2)CMOS. 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.

The Company also provides several software algorithms that support in-system 
programming of the Company's ISP devices.  These software products include 
ispCODE-TM-, 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 1997, the number of installed seats of the Company's software 
development tools, as measured by the Company, grew from over 10,000 to over 
17,000. The Company plans to continue to enhance and expand its development 
tool offerings.

LOW-DENSITY PLDS

The Company offers the industry's broadest line of low-density CMOS PLDs 
based on its 16 families of GAL products offered in over 200 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 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

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 high-density PLDs, improvements 
of its proprietary ISP products and E(2)CMOS processes technologies, 
performance enhancement and cost reduction of existing products, 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 $22.9 million, $26.8 million and $27.8 
million in fiscal years 1995, 1996 and 1997, 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 most 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 an 
agreement 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 
through S MOS or from UMC would have a material adverse effect on the 
Company's business. See "Factors Affecting Future Results." 


                                       7


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 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, peripherals, 
instrumentation, industrial controls and military systems. The Company 
believes its distribution channel is a cost-effective means of reaching end 
customers. 

At March 29, 1997, the Company had 19 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 21 
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, Denver, 
Los Angeles, Minneapolis, Orlando, Portland, Raleigh, San Diego, San Jose, 
Hong Kong, London, Munich, Paris, Seoul, Stockholm, Taipei and Tokyo. 

International revenues, including those from Canada, accounted for 47%, 48% 
and 49% of the Company's revenues in fiscal 1995, 1996 and 1997, respectively.
Revenues from Europe were $24.5 million, $37.9 million 


                                       8


and $ 39.9 million, and from Asia were $40.6 million, $52.4 million and $ 
52.6 million, in fiscal 1995, 1996 and 1997, 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 end customer accounted for more than 5% of revenue in either fiscal 
1995, 1996 or 1997.   Two distributors accounted for approximately 12% and 
11% of revenue in fiscal 1995.  One distributor accounted for approximately 
11% of revenue in fiscal 1996.  No distributor accounted for more than 10% of 
revenue in fiscal 1997.

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 CMOS PLD market include product 
features, price, customer support, and sales, marketing and distribution 
strength. In the high-density segment, 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 life 
cycle. 

In the high-density PLD market, the Company primarily competes directly with 
Advanced Micro Devices ("AMD") and Altera, both of which offer competing CPLD 
products. The Company also competes indirectly with manufacturers of FPGA 
devices such as Actel, Lucent, and Xilinx 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 low-density PLD market, the Company competes primarily with AMD, a 
licensee of the Company's GAL patents, which offers a full line of E(2)CMOS 
GAL-compatible PLDs. Altera, 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 


                                       9


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 
technology 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 
patents 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 
under the European Patent Convention. 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. The Company has received a letter from a 
semiconductor manufacturer stating that it believes a number of its patents, 
related to product packaging, cover certain products sold by the Company. 
While the manufacturer has offered to license certain of such patents to the 
Company, there can be no assurance, on this or any other claim which may be 
made against the Company, that the Company could obtain a license on terms or 
under conditions that would be favorable to 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. The Company's products are 
manufactured in Japan at Seiko Epson's wafer fabrication facilities and 
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. Subject to certain conditions set 
forth in the agreement, Seiko Epson has agreed to supply, and the Company has 
agreed to receive, such wafers at a price (in Japanese yen) and volume 
expected to achieve full repayment of the advance 


                                       10


over a three- to four-year period. 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 to be delivered over the same period. The agreement calls 
for wafers to be supplied by Seiko Epson through S MOS pursuant to a purchase 
agreement concluded with S MOS. Total wafer receipts under these agreements 
aggregated approximately $30.2 million as of March 29, 1997.

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 $90 million, payable over two years, to Seiko Epson to 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 additonal wafer supply under similar terms.  The first payment 
pursuant to this agreement, approximately $17.0 million, was made during March
1997.

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 will invest 
approximately $53 million, payable in three installments, for a 10% equity 
interest in UICC  and the right to receive a percentage of the facility's 
wafer production at market prices.  The timing of the payments is related to 
certain milestones in the development of the advanced semiconductor 
manufacturing facility.  The first payment, in the amount of $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 is 
anticipated to be required within the six-month period ending December 1997.

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 terminates, with respect to certain patents 
asserted by AMD, 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. 


                                       11


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, the timing of new product introductions, 
price erosion, product obsolescence, substantial adverse currency exchange 
rate movements, variations in product mix, scheduling, rescheduling and 
cancellation of large orders, competitive factors, the availability of 
manufacturing capacity and wafer supply, the ability to achieve volume 
production at Seiko Epson's new eight-inch facility or UICC, the ability to 
develop and implement new process technologies, fluctuations in manufacturing 
yields, changes in effective tax rates and 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 high-density products.  To the extent 
that this revenue growth does not materialize, the Company's operating 
results would be adversely affected.

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.

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 and 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 Company does not manufacture finished silicon wafers.  Its products, 
however, 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.

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 1997, the Company was 
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 1998, there can be 


                                       12


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.  

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.

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 E(2)CMOS 
process technology.  Successful implementation of the Company's proprietary 
E(2)CMOS 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 new eight-inch facility or UICC.  Accordingly, there can be no 
assurance that volume production at Seiko Epson's new eight-inch facility or 
UICC will be achieved in the near term or at all.  The manufacture of high 
performance E(2)CMOS 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.

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 


                                       13


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 finished silicon wafers are assembled and packaged by 
independent subcontractors located in the Philippines, South Korea and 
Malaysia, Hong Kong 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.

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 and with acceptable margins as well as enhancing the 
performance of its existing products. The success of new products, including 
the Company's high-density 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 high-density 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 high-density 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.

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 affected 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 


                                       14


characteristics superior to the Company's technologies could adversely affect 
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.

In an effort to secure additional wafer supply, the Company may from time to 
time consider various arrangements, including joint ventures with, minority 
investments in, advanced purchase payments to, loans to or similar 
arrangements with independent wafer manufacturers in exchange for committed 
production capacity.  Such arrangements are becoming 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 will invest a total of 
approximately $53 million for a 10% equity interest in a separate Taiwanese 
company (UICC) providing for the formation of a joint venture with UMC and 
several other companies for the purpose of building and operating an advanced 
semiconductor manufacturing facility.  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 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.  
The Company has received a letter from a semiconductor manufacturer stating 
that it believes a number of its patents related to product packaging cover 
certain products sold by the Company.  While the manufacturer has offered to 
license certain of such patents to the Company, there can be no assurance, on 
this or any other claim which may be made against the Company, that the 
Company could obtain a license on terms or under conditions that would be 
favorable to the Company.  In addition, there can be no assurance that other 
intellectual property claims will not be made against the Company in the 
future or that the Company will not be prohibited from using the technologies 
subject to such claims or be required to obtain licenses and make 
corresponding royalty payments for past or future use.


                                       15


International revenues accounted for 47%, 48% and 49% of the Company's 
revenues for fiscal 1995, 1996 and 1997, 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 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 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 new product, both silicon 
and software, and process technology development.  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 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 South Korea, the 
Philippines, Hong Kong, and Malaysia.  Although the Company has not 
experienced any interruption in supply from its subcontractors, the social 
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 
changes in currency exchange rates, tax laws,  tariffs, or freight rates, or 
interruptions in air transportation, could have a material adverse effect on 
the Company's results of operations.

EMPLOYEES

As of March 29, 1997, the Company had 531 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 under a five-year term which 
expires in August 1998. 

The Company leases space in various locations in the United States for its 
domestic sales offices, and also leases space in Hong Kong, London, Munich, 
Paris, Seoul, Stockholm, Taipei and Tokyo for its international sales 
offices. The Company owns a 13,000 square foot research and development 
facility and approximately 6,000 square feet of dormitory facilities in 
Shanghai.

                         ON FINANCIAL STATEMENT SCHEDULE


To the Board of Directors

Our audits of the consolidated financial statements referred to in our report
dated April 16, 1997 appearing in the 1997 Annual Report to Stockholders of
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

presents fairly, in all material respects, the information set forth therein
when read in conjunction with the related consolidated financial statements.
