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
of the factors set forth in "Factors Affecting Future Results" and elsewhere
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. The Company introduced
ISP devices to the industry in 1992. 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 communication, computing, industrial and
military systems. Lattice was founded in 1983 and is based in Hillsboro,
Oregon.

In June 1999, the Company acquired Vantis Corporation from Advanced Micro
Devices ("AMD") for approximately $500 million in cash. Vantis will be
integrated into the operations of the Company and remain a wholly-owned
subsidiary of the Company. The business of Vantis is substantially similar to
that of the Company including markets, products, customers, work force and
revenues, which are not included in the descriptions, Technology, Products,
Product Development, Operations, Marketing, Sales, Customers, Backlog,
Licenses and Agreements and Year 2000 Compliance contained herein. Prior to
the acquisition, Vantis relied upon its parent company, AMD, for most
manufacturing activities as well as financial and administrative services.
As a part of the acquisition agreement between AMD and the Company, AMD has
agreed to continue to perform many of these services for defined periods or
at the Company's option, shorter periods. The transaction is being accounted
for using the purchase method in the Company's consolidated financial
statements beginning in the period ended July 3, 1999. As part of the
acquisition agreements, AMD and the Company have agreed to sign an election
under the Internal Revenue Code which will enable the Company to take a tax
deduction for the purchase price amortized over periods up to 15 years. The
primary benefits expected to result from this acquisition are accelerated
development of new products and new technologies, and the ability to reach
and service a greater number of customers.

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 digital electronic
equipment including communication, computing, industrial and military
systems. According to WSTS, a semiconductor industry association, logic


2
accounted for approximately 28% of the estimated $109 billion worldwide
digital integrated circuit market in 1998. 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 equipment 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 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.

The PLD market has two primary segments: 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 the complex PLD
("CPLD") and field programmable gate array ("FPGA") architectures.

Products based on these alternative high-density PLD architectures are
generally optimal for different types of logic functions, although many logic
functions can be implemented using 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 ("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 pioneered the development of ISP products which utilize 5-volt or
3.3-volt programming signals and, as a result, can be configured and
reconfigured by a system designer without being removed from the printed
circuit board. Standard E2CMOS programmable logic devices require a 12-volt
programming signal and therefore must be removed from the printed circuit
board and programmed using specialized hardware. ISP devices offer


3
enhanced flexibility versus standard PLDs and provide significant customer
benefits. 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.

PRODUCTS

ISP PRODUCTS

SILICON. The Company first entered the ISP market in fiscal 1993 and
currently offers seven distinct families of ISP products, each consisting of
multiple devices. The Company is currently shipping over 300 performance,
package and temperature range combinations of 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
propagation delay), densities of 2,000 to 8,000 gates and is available in 44-
to 128-pin standard surface mount packages.

ispLSI 2000E/VE: Introduced in fiscal 1999, the SuperFAST-TM- 5 volt ispLSI
2000E and 3.3 volt ispLSI 2000VE families utilize an architecture designed
for input/output ("I/O") intensive applications and are the industry's
fastest CPLDs. These families provides performance of up to 200 MHz (3.5
nanosecond propagation delay), densities of 1,000 to 8,000 gates and are
available in 44-to 208-pin standard surface mount packages.

ispLSI 3000/E: The ispLSI 3000/E family incorporates an enhanced CPLD
architecture to target higher density applications while retaining high
performance. This family provides densities of 7,000 to 20,000 gates,
performance of up to 125 MHz (7.5 nanosecond propagation delay), and is
available in 160- to 432-pin surface mount packages.

ispLSI 5000V: Introduced in fiscal 1999, the SuperWIDE-TM- 3.3-volt ispLSI
5000V family is based on an entirely new CPLD architecture that incorporates
a 68-input logic block. This innovative logic block architecture, the
industry's widest, makes the 5000V family an ideal solution for 32-bit and
emerging 64-bit control logic applications. This family provides densities
of 12,000 to 24,000 gates, performance of up to 125 MHz (7.5 nanoseconds
propagation delay), and is available in 192- to 388-pin surface mount
packages.

ispLSI 8000: Introduced in fiscal 1999, the SuperBIG-TM- 5-volt ispLSI 8000
family utilizes an entirely new hierarchical CPLD architecture designed to
efficiently implement large, register intensive, logic applications. This
family provides densities of 25,000 to 50,000 gates, performance of up to 110
MHz (8.5 nanoseconds propagation delay), and is available in 272- to 492-pin
surface mount packages.

ispGAL-Registered Trademark-: This proprietary family combines in-system
programmability with the industry standard 22V10 low-density architecture.
Offered with performance of up to 200 MHz, (5.0 nanosecond propagation
delay), the ispGAL family is available in both 5-volt and 3.3-volt operating
supply versions.


4
ispGDX-TM-:   This family extends in-system programmability to the circuit
board level using an innovative 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 ISP products are supported by ispEXPERT-TM-,
the Company's third generation software development tool suite. Supporting
both the PC and UNIX platforms, ispEXPERT allows a customer to enter, verify
and synthesize a design, perform logic simulation and timing analysis, assign
I/O pins and critical speed paths, debug and floorplan a design, execute
automatic place and route tasks and download a program to an ISP device.
Seamlessly integrated with third-party electronic design automation ("EDA")
environments, ispEXPERT leverages customers' prior investments in products
offered by Aldec, Cadence, Mentor Graphics, OrCAD, Synopsys, Synplicity,
Viewlogic and Veribest. In the future, the Company plans to continue to
enhance and expand its development tool offerings.

The Company also provides a variety of software algorithms that support
in-system programming of the Company's ISP devices via multiple formats and
mechanisms. These software products include ispCODE-TM-, Turbo
ispDOWNLOAD-TM-, ispREMOTE-TM-, ispATE-TM-, and ispSVF-TM-.

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 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 substantial emphasis on new product development and
believes that continued investment in this area is required to maintain its
competitive position. See "Factors Affecting Future Results." The Company's
product development activities emphasize new proprietary ISP products,
enhancement of existing products and process technologies and improvement of
software development tools. Product development activities occur in the
Company's Hillsboro, Oregon headquarters, Milpitas, California product
development center and Corsham, England and Shanghai, China design centers.


5
Research and development expenses were $27.8 million, $32.0 million and $33.2
million in fiscal years 1997, 1998 and 1999, respectively. The Company
expects to continue to make significant investments in research and
development in the future.

OPERATIONS

The Company does not manufacture its own silicon wafers and has historically
maintained strategic relationships with large semiconductor manufacturers to
source finished silicon wafers. This allows internal resources to be focused
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 Epson Electronics America, Inc. ("EEA", formerly SMOS 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 EEA on a periodic basis. In addition,
the Company receives silicon wafers from the United Microelectronics
Corporation Group of affiliated companies ("UMC Group") 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 Group." A significant interruption or
shortage in wafer supply from Seiko Epson through EEA or from the UMC Group
would have a material adverse effect on the Company's business. A significant
or unexpected deterioration in the silicon wafer quality or yield levels
achieved by Seiko Epson or the UMC Group could also 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. See "Factors Affecting Future Results."

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


6
The Company sells its products directly to end customers through a network of
independent manufacturers' representatives and indirectly through a network
of independent distributors. The Company also employs a direct sales
management and field applications engineering organization to support its end
customers and indirect sales resources. The Company's end customers are
primarily original equipment manufacturers in the fields of communication,
computing, industrial and military systems.

At April 3, 1999, the Company utilized 21 manufacturers' representatives and
four distributors in North America. Arrow Electronics, Inc., Avnet, Inc. and
Marshall Industries provide full distribution coverage, while Future
Electronics provides regional distribution coverage in Canada. The Company
has also established export 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
export 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 support to end customers 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. These offices are located in the metropolitan
areas of Atlanta, Boston, Chicago, Dallas, Los Angeles, Minneapolis, Orange
County, Orlando, Portland, Raleigh, San Diego, San Jose, Hong Kong, London,
Milan, Munich, Paris, Seoul, Shanghai, Taipei and Tokyo.

Export sales accounted for 49%, 51% and 50% of the Company's total revenue in
fiscal 1997, 1998 and 1999, respectively. Both export and domestic sales are
denominated in U.S. dollars, with the exception of sales to Japan, which are
dominated in yen. If export sales decline significantly there will be a
material adverse impact on the Company's business. See "Factors Affecting
Future Results."

The Company's products are sold to a large and diverse group of customers. No
individual customer or distributor accounted for more than 10% of total
revenue in fiscal 1997, 1998 or 1999. No export sales to any individual
country accounted for more than 10% of total revenue in fiscal 1997, 1998 or
1999.

BACKLOG

The Company's backlog of scheduled and released orders as of April 3, 1999
was approximately $30.4 million as compared to approximately $31.8 million as
of March 28, 1998. The Company's backlog consists of direct OEM and
distributor orders scheduled for delivery within the next 90 days.
Distributor orders accounted for the majority of the backlog in both periods.
Direct OEM customer orders may be changed, rescheduled or cancelled under
certain circumstances without penalty prior to shipment. Additionally,
distributor orders generally may be changed, rescheduled or cancelled without
penalty prior to shipment. Furthermore, distributor shipments are subject to
rights of return and price adjustment. Revenue associated with distributor
shipments is not recognized until the product is resold to an end customer.
In recent periods, the majority of the Company's revenue has resulted from
orders placed and filled within the same period ("turns orders"). By
definition, turns orders are not captured in a backlog measurement made at
the beginning of a period. The Company does not anticipate a


7
significant change in this business pattern.  For all these reasons, backlog
as of any particular date should not be used as a predictor of revenue for
any future period.

COMPETITION

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

The principal competitive factors in the PLD market include 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 density, 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
and Xilinx, both 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.

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. See "Factors Affecting Future 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. See "Factors Affecting Future Results."

The Company holds numerous 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


8
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. See "Factors Affecting Future Results."

LICENSES AND AGREEMENTS

SEIKO EPSON/EPSON ELECTRONICS AMERICA, INC.

EEA, 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 EEA. Prices for the wafers obtained from EEA are
reviewed and adjusted periodically.

In July 1994, the Company entered into an advance production payment
agreement with Seiko Epson and EEA, 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 EEA pursuant to a purchase agreement concluded with EEA.
As of April 3, 1999, 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 EEA under which it agreed to advance
approximately $85 million, payable upon completion of specific milestones, 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 EEA pursuant to purchase agreements concluded with EEA. 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 GROUP

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 between fiscal 1996 and fiscal 1998


9
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 has been
substantially recovered by an insurance settlement and additional investment
income. In June 1999, the Board of Directors of UICC and the Board of
Directors of UMC voted in favor of merging UICC into UMC. The matter is
scheduled for a UMC shareholder vote in July 1999. The Company has received
assurance that its capacity rights would be preserved in the event of this
merger. Accordingly, management of the Company believes that its investment
in UICC is not impaired.

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 risks. These risks include, but are not limited to:

OUR WAFER SUPPLY COULD BE INTERRUPTED OR REDUCED AND RESULT IN A SHORTAGE OF
FINISHED PRODUCTS AVAILABLE FOR SALE.

We do not manufacture finished silicon wafers. Currently all our silicon
wafers are manufactured by Seiko Epson in Japan and the UMC Group, a group of
affiliated companies in Taiwan. If Seiko Epson, through its U.S. affiliate
Epson Electronics America, or the UMC Group significantly interrupts or
reduces our wafer supply, our operating results would be adversely affected.

In the past, we have experienced delays in obtaining wafers and in securing
supply commitments from our foundries. At present, we anticipate that our
supply commitments are adequate. However, these existing supply commitments
may not be sufficient for us to satisfy customer demand in future periods.
Additionally, during times of capacity shortage, notwithstanding our supply
commitments we may still have difficulty in obtaining wafer deliveries
consistent with the supply commitments. We negotiate wafer prices and supply
commitments on at least an annual basis. If Seiko Epson, Epson Electronics
America or the UMC Group reduces our supply commitment or increases our wafer
prices, and we cannot find alternative sources of wafer supply, our operating
results could be adversely affected.

Many other factors that could disrupt our wafer supply are beyond our
control. Since worldwide manufacturing capacity for silicon wafers is limited
and inelastic, we could be adversely affected by significant industry wide
increases in overall wafer demand or interruptions in wafer supply.
Additionally, a disruption of Seiko Epson's or the UMC Group's foundry
operations as a result of a fire, earthquake or other natural disaster would
disrupt our wafer supply and would have an adverse effect on our operating
results.

IF OUR FOUNDRY PARTNERS EXPERIENCE QUALITY OR YIELD PROBLEMS, WE MAY FACE A
SHORTAGE OF FINISHED PRODUCTS AVAILABLE FOR SALE.

We depend on our foundries to deliver reliable silicon wafers with acceptable
yields in a timely manner. As is common in our industry, we have experienced
wafer yield problems and delivery delays in the past. If our


10
foundries are unable to produce silicon wafers that meet our specifications,
with acceptable yields, for a prolonged period, our operating results could
be adversely affected.

Substantially all of our revenues are derived from products based on a
specialized silicon wafer manufacturing process technology called
E2CMOS-Registered Trademark-. The reliable manufacture of high performance
E2CMOS semiconductor wafers is a complicated and technically demanding
process requiring:
- - a high degree of technical skill;
- - state-of-the-art equipment;
- - the absence of defects in the masks used to print circuits on a wafer;
- - the elimination of minute impurities and errors in each step of the
fabrication process; and
- - effective cooperation between the wafer supplier and the circuit designer.

As a result, our foundries may experience difficulties in achieving
acceptable quality and yield levels when manufacturing our silicon wafers.

OUR PRODUCTS MAY NOT BE COMPETITIVE IF WE ARE UNSUCCESSFUL IN MIGRATING OUR
MANUFACTURING PROCESSES TO MORE ADVANCED TECHNOLOGIES.

In order to develop new products and maintain the competitiveness of existing
products, we need to migrate to more advanced wafer manufacturing processes
that utilize larger wafer sizes and smaller device geometries. We may also
utilize additional foundries. Since we depend upon foundries to provide their
facilities and support for our process technology development, we may
experience delays in the availability of advanced wafer manufacturing process
technologies at existing or new wafer fabrication facilities. As a result,
volume production of our advanced E2CMOS-Registered Trademark- process
technologies at the new fabs of Seiko Epson, the UMC Group or future
foundries may not be achieved. This could have an adverse effect on our
operating results.

WE MAY BE UNSUCCESSFUL IN DEFINING AND DEVELOPING NEW PRODUCTS REQUIRED TO
MAINTAIN OR GROW OUR BUSINESS.

As a semiconductor company, we operate in a dynamic environment marked by
rapid product obsolescence. Our future success depends on our ability to
introduce new or improved products that meet customer needs while achieving
acceptable margins. If we fail to introduce these new products in a timely
manner or these products fail to achieve market acceptance, our business and
financial condition will be adversely affected.

The introduction of new products in a dynamic market environment presents
significant business challenges. Product development commitments and
expenditures must be made well in advance of product sales. The success of a
new product depends on accurate forecasts of long-term market demand and
future technology developments.

Our future revenue growth is dependent on market acceptance of our new
proprietary ISP-TM- product families and the continued market acceptance of our
proprietary software development tools. The success of these products is
dependent on a variety of specific technical factors including:
- - successful product definition;
- - timely and efficient completion of product design;


11
- -    timely and efficient implementation of wafer manufacturing and assembly
processes;
- - product performance; and
- - the quality and reliability of the product.

If, due to these or other factors, our new ISP products do not achieve market
acceptance, our business and financial condition will be adversely affected.

WE MAY EXPERIENCE UNEXPECTED DIFFICULTIES INTEGRATING VANTIS CORPORATION.

Integration of Vantis has begun. If integration is unsuccessful, or more
difficult, or more time consuming than originally planned, we may incur
unexpected disruptions to our ongoing business. These disruptions may have
an adverse effect on our operations and financial results. Further, the
following specific factors may adversely affect our ability to smoothly and
quickly integrate the business of Vantis:

- - We may experience unexpected losses of key employees or customers;

- - We may experience difficulties and delays in conforming the standards,
processes, procedures and controls of our two businesses;

- - We may experience unexpected costs and discover unexpected liabilities;

- - We may not receive product manufacturing and administrative services from
Vantis former parent corporation, AMD at a level of quality and timeliness
consistent with the historical delivery of this support;

- - We may not achieve expected levels of revenue growth, cost reduction and
profitability improvement; and

- - We may not be able to coordinate our new product and process development
in a way which permits us to bring new technologies to the market in a
timely manner.

CONTINUED DETERIORATION OF CONDITIONS IN ASIA MAY DISRUPT OUR EXISTING SUPPLY
ARRANGEMENTS AND RESULT IN A SHORTAGE OF FINISHED PRODUCTS AVAILABLE FOR SALE.

Our two silicon wafer suppliers operate fabs located in Asia. Our finished
silicon wafers are assembled and tested by independent subcontractors located
in Hong Kong, Malaysia, the Philippines, South Korea and Taiwan. A prolonged
interruption in our supply from any of these subcontractors could have an
adverse effect on our operating results.

Although we have yet not experienced significant supply interruptions, the
economic, financial, social and political situation in Asia has recently been
volatile. Financial difficulties, governmental actions or restrictions,
prolonged work stoppages or any other difficulties experienced by these
suppliers may disrupt our supply and could have an adverse effect on our
operating results.

Our wafer purchases from Seiko Epson are denominated in Japanese yen. The
value of the dollar with respect to the yen has fluctuated in the past and
may not remain stable in the future. Future substantial deterioration of
dollar-yen exchange rates could have an adverse effect on our operating
results.

EXPORT SALES ACCOUNT FOR A SUBSTANTIAL PORTION OF OUR REVENUES AND MAY
DECLINE IN THE FUTURE DUE TO ECONOMIC AND GOVERNMENTAL UNCERTAINTIES.

Our export sales are affected by unique risks frequently associated with
foreign economies including:
- - changes in local economic conditions;


12
- -    exchange rate volatility;
- - governmental controls and trade restrictions;
- - export license requirements and restrictions on the export of technology;
- - political instability;
- - changes in tax rates, tariffs or freight rates;
- - interruptions in air transportation; and
- - difficulties in staffing and managing foreign sales offices.

For example, our export sales have recently been affected by the Asian
economic crisis. Significant changes in the economic climate in the foreign
countries where we derive our export sales could have an adverse effect on
our operating results.

IF OUR ASSEMBLY AND TEST SUBCONTRACTORS EXPERIENCE QUALITY OR YIELD PROBLEMS,
WE MAY FACE A SHORTAGE OF FINISHED PRODUCTS AVAILABLE FOR SALE.

We rely on subcontractors to assemble and test our devices with acceptable
quality and yield levels. As is common in our industry, we have experienced
quality and yield problems in the past. If we experience prolonged quality or
yield problems in the future, there could be an adverse affect on our
operating results.

The majority of our revenue is derived from semiconductor devices assembled
in advanced packages. The assembly of advanced packages is a complex process
requiring:
- - a high degree of technical skill;
- - state-of-the-art equipment;
- - the absence of defects in lead frames used to attach semiconductor devices
to the package;
- - the elimination of raw material impurities and errors in each step of the
process; and
- - effective cooperation between the assembly subcontractor and the device
manufacturer.

As a result, our subcontractors may experience difficulties in achieving
acceptable quality and yield levels when assembling and testing our
semiconductor devices.

THE CYCLICAL NATURE OF THE SEMICONDUCTOR INDUSTRY MAY LIMIT OUR ABILITY TO
MAINTAIN OR GROW REVENUE AND PROFIT LEVELS DURING FUTURE INDUSTRY DOWNTURNS.

The semiconductor industry is highly cyclical, to a greater extent than other
less dynamic or less technology-driven industries. In the past, our financial
performance has been negatively affected by significant downturns in the
semiconductor industry as a result of:
- - the cyclical nature of the demand for the products of semiconductor
customers;
- - general reductions in inventory levels by customers;
- - excess production capacity; and
- - accelerated declines in average selling prices.

If these or other conditions in the semiconductor industry occur in the future,
there could be an adverse effect on our operating results.


13
OUR STOCK PRICE MAY CONTINUE TO EXPERIENCE LARGE SHORT-TERM FLUCTUATIONS
WHICH MAY RESULT IN INVESTORS LOSING ALL OR PART OF THEIR INVESTMENT.

In recent years, the price of our common stock has fluctuated greatly. These
price fluctuations have been rapid and severe and have left investors little
time to react. The price of our common stock may continue to fluctuate
greatly in the future due to a variety of company specific factors,
including:
- - quarter to quarter variations in our operating results;
- - shortfalls in revenues or earnings from levels expected by securities
analysts;
- - announcements of technological innovations or new products by other
companies.

WE MAY NOT BE ABLE TO SUCCESSFULLY COMPETE IN THE HIGHLY COMPETITIVE
SEMICONDUCTOR INDUSTRY.

The semiconductor industry is intensely competitive and many of our direct
and indirect competitors have substantially greater financial, technological,
manufacturing, marketing and sales resources. If we are unable to compete
successfully in this environment, our future results will be adversely
affected.

The current level of competition in the programmable logic market is high and
may increase as our market expands. We currently compete directly with
companies that have licensed our products and technology or have developed
similar products. We also compete indirectly with numerous semiconductor
companies that offer products and solutions based on alternative
technologies. These direct and indirect competitors are established
multinational semiconductor companies as well as emerging companies. We also
may experience significant competition from foreign companies in the future.

WE MAY FAIL TO RETAIN OR ATTRACT THE SPECIALIZED TECHNICAL AND MANAGEMENT
PERSONNEL REQUIRED TO SUCCESSFULLY OPERATE OUR BUSINESS.

To a greater degree than most non-technology companies or larger technology
companies, our future success depends on our ability to attract and retain
highly qualified technical and management personnel. As a mid-sized company,
we are particularly dependent on a relatively small group of key employees.
Competition for skilled technical and management employees is intense within
our industry. As a result, we may not be able to retain our existing key
technical and management personnel. In addition, we may not be able to
attract additional qualified employees in the future. If we are unable to
retain existing key employees or are unable to hire new qualified employees,
our operating results could be adversely affected.

IF WE ARE NOT ABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OUR
FINANCIAL RESULTS AND COMPETITIVE POSITION MAY SUFFER.

Our success depends in part on our proprietary technology. However, we may
fail to adequately protect this technology. As a result, we may lose our
competitive position or face significant expense to protect or enforce our
intellectual property rights.

We intend to continue to protect our proprietary technology through patents,
copyrights and trade secrets. Despite this intention, we may not be
successful in achieving adequate protection. Claims allowed on any of our
patents may not be sufficiently broad to protect our technology. Patents
issued to us also may be challenged, invalidated or circumvented. Finally,
our competitors may develop similar technology independently.


14
Companies in the semiconductor industry vigorously pursue their intellectual
property rights. If we become involved in protracted intellectual property
disputes or litigation we may utilize substantial financial and management
resources, which could have an adverse effect on our operating results. We
may also be subject to future intellectual property claims or judgements. If
these were to occur, we may not be able to obtain a license on favorable
terms or without our operating results being adversely affected.

YEAR 2000 COMPLIANCE

The Company is currently working to address the potential impact of the Year
2000 on the processing of information by the Company's computerized systems,
including interfaces to its business partners.

In June 1999, the Company completed its planned Year 2000 compliance
activities with respect to its products and internal systems, software,
equipment and facilities. Based solely on these activities, management
believes that all products and material internal systems, software, equipment
and facilities are currently Year 2000 compliant. The Company does not
anticipate that potential Year 2000 issues will have a material adverse
impact on the Company's financial position or operating results. In
aggregate, approximately $2 million in expenses were incurred to fund Year
2000 compliance activities.

However, the Company could be adversely impacted if any of our critical
business partners were to experience a severe business interruption due to a
failure to address their internal Year 2000 issues in a timely manner. The
most reasonably likely worst case Year 2000 scenario is a temporary
disruption in supplier deliveries or customer shipments. If a severe
disruption occurs in either of these two areas and is not corrected in a
timely manner, a revenue or profit shortfall may result in the first half of
calendar year 2000. Based solely on responses received to date from our
business partners, the Company has no reason to believe that there will be
such a material adverse impact. However, if the responses received from our
business partners are inaccurate or happen to change, then there could be
such a material adverse impact. Management plans to evaluate Year 2000
business interruption scenarios and develop appropriate contingency plans by
September 1999.

EMPLOYEES

As of April 3, 1999 the Company had 546 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 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 headquarters are located in three adjacent buildings
owned by the Company in Hillsboro, Oregon comprising a total of approximately
200,000 square feet. The Company leases, through 2001, a 41,000 square foot
product development facility in Milpitas, California. The Company owns a
13,000 square foot research and development facility and approximately 6,000
square feet of dormitory facilities in Shanghai, China. The Company recently
opened a third design center in Corsham, England in a facility leased on a
short-term basis. The Company leases, on a short-term basis, office
facilities for its domestic and international sales offices.

Vantis leases corporate headquarter facilities in Sunnyvale, California, as
well as research and development facilities in Texas and Colorado, and sales
offices worldwide.


15
ITEM 3.  LEGAL PROCEEDINGS.

ADVANCED MICRO DEVICES, INC. V. ALTERA CORPORATION (CASE NO. C-94-20567-RMW,
N. D. CAL.). This litigation, which began in 1994, involves multiple claims
and counterclaims for patent infringement relating to Vantis Corporation's
(formerly a wholly owned subsidiary of Advanced Micro Devices, Inc. ("AMD"))
and Altera Corporation's programmable logic devices. The Company assumed this
litigation in its acquisition from AMD of Vantis Corporation. In April 1999,
the Federal Court of Appeal reversed the earlier jury and Court decisions and
held that Altera is not licensed to the eight AMD patents-in-suit. Also in
April 1999, and following the decision of the Federal Court of appeal, Altera
filed a petition for rehearing. In June 1999, the Federal Court of Appeal
denied Altera's petition for rehearing.

In connection with its acquisition of Vantis Corporation, Lattice has agreed
to assume both the claims against Altera and the claims by Altera against
AMD. Although there can be no assurance as to the results of such litigation,
based upon information presently known to management, we do not believe that
the ultimate resolution of this lawsuit will have a material adverse effect
on our business. The foregoing statement constitutes a forward-looking
statement and the actual results may differ materially depending on a number
of factors, including new court decisions and additional counterclaims made
by other parties to such litigation.

ITEM 6. SELECTED FINANCIAL DATA.

The information required by this Item is set forth in the Company's 1999 Annual
Report to Stockholders at page 15 under the caption "Selected Financial Data",
which information is incorporated herein by reference.


19
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.

The information required by this Item is set forth in the Company's 1999
Annual Report to Stockholders at pages 10 through 14 under the caption
"Management's Discussion and Analysis of Financial Condition and Results of
Operations", which information is incorporated herein by reference.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

As of April 3, 1999 and March 28, 1998, the Company's investment portfolio
consisted of fixed income securities of $293.4 million and $245.5 million
respectively. As with all fixed income instruments, these securities are
subject to interest rate risk and will decline in value if market interest
rates increase. If market rates were to increase immediately and uniformly by
10% from levels as of April 3, 1999 and March 28, 1998, the decline in the
fair value of the portfolio would not be material. Further, the Company has
the ability to hold its fixed income investments until maturity and,
therefore, the Company would not expect to recognize such an adverse impact
in income or cash flows.

The Company has international subsidiary and branch operations. Additionally,
the majority of the Company's silicon wafer purchases are denominated in
Japanese yen. The Company is therefore subject to foreign currency rate
exposure. To mitigate rate exposure with respect to yen-denominated wafer
purchases, the Company maintains yen-denominated bank accounts and bills it
Japanese customers in yen. The yen bank deposits are utilized to hedge
yen-denominated wafer purchases against specific and firm wafer purchases. If
the foreign currency rates fluctuate by 10% from rates at April 3, 1999 and
March 28, 1998, the effect on the company's consolidated financial statements
would not be material. However, there can be no assurance that there will not be
a material impact in the future.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
