assurance that such expectations will be achieved. The Company undertakes no
obligation to update publicly any forward-looking statements, whether as a
result of new information, future events or otherwise.

         Dallas Semiconductor Corporation (the "Company" or "Dallas
Semiconductor") designs, manufactures and markets electronic chips and
chip-based subsystems. Founded in 1984, the Company uses customer problems as an
entry point to develop products with widespread applications. The Company is
committed to new product development as a means to increase future revenues and
diversify its markets, product offerings and customers.

         The Company uses its advanced technologies to gain a competitive edge
over the traditional approaches to semiconductors. Combining lithium energy
cells with low-power complimentary metal oxide silicon ("CMOS") chips can power
them for the useful life of the equipment. Direct laser writing can enhance chip
capabilities with higher levels of precision and/or unique identities. Special
packaging gives improved functionality to silicon chips.

         In its fifteen-year history, Dallas Semiconductor has developed 326
proprietary base products with over 2,000 variations shipped to more than 15,000
customers worldwide. A direct sales force and distribution network sell to
original equipment manufacturers (OEMs) of personal computers and workstations,
scientific and medical equipment, industrial controls, automatic identification,
telecommunications, consumer electronics and other markets.

         The Company organizes its products into product categories sharing
common technologies, markets or applications as shown below. See "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations" of this report for the relative size of the Company's main product
categories.

         Communications                              Nonvolatile RAMs
         System Extension                            Microcontrollers
         Automatic Information                       Computer Timekeeping
         Commercial Timekeeping                      Others

PRODUCT DEVELOPMENT

         The Company developed 34 new proprietary base products during the 1998
fiscal year. The Company's research and development expenditures for fiscal 1998
were $47 million, compared to expenditures in 1997 and 1996 of $46 million and
$35 million, respectively. Dallas Semiconductor intends to continue to commit
substantial resources to the development of new products. There can be no
assurance, however, that such products, if developed, will gain market
acceptance.

PRODUCTS

         Descriptions of the Company's product categories are as follows.

         COMMUNICATIONS. An emerging and rapidly growing market exists for high
capacity voice, data and video transmission. High capacity digital links in
North America and Europe/Asia are known as T1/E1 networks. A set of highly
integrated chips developed by Dallas Semiconductor addresses the requirements of
these protocols and provides one of the most cost-effective solutions available
in the industry while minimizing board space and power

                                      -2-

<PAGE>   3


requirements. Transmission line terminators, such as the SCSI (small computer
system interface) Terminator, quiet transmission lines between computers and
peripherals, such as disk drives, permitting high speed, high integrity data
transmissions.

         SYSTEM EXTENSION. This product category provides complete solutions to
common problems facing many systems designers. Nearly all of the products
include both analog and digital circuitry on the same chip. Battery Management
Products simplify the complex task of optimally using rechargeable battery packs
in portable equipment. Direct-to-Digital Temperature Sensors help manage the
growing thermal problems facing designers as the inevitable march to put more
power into shrinking form factors continues. Digital Potentiometers permit a
digital microprocessor to easily control an analog parameter such as volume or
display screen brightness. CPU Supervisors monitor the power supply voltages in
a system and issue a warning to the system should any fall below a critical
value.

         AUTOMATIC INFORMATION. The Company has developed a family of Automatic
Information products, including iButtons(TM) that can be attached to an object,
or carried by a person, which identifies the user and holds relevant
information. Unlike barcodes, users do not need to refer to a remote database to
decipher the code - the information is available in the device itself. These
read/write data carriers can also be updated via computer while affixed to an
object. Automatic Information chips can facilitate automation by tracking a work
piece as it travels along an assembly line; they can also be used to identify
people for access to secure areas. Using Dallas Semiconductor's 1-Wire(TM)
technology, a memory chip can be read or written with the touch of a probe.
iButton devices are packaged in a stainless steel MicroCan(TM) 16mm in diameter.
The cryptographic iButton with Java(TM) is a new product that enables a standard
PC using a Java powered browser to send secure communications across public
networks, such as the Internet, to facilitate electronic commerce or to send
private e-mail messages. This class of device is so secure that it is has been
certified to pass the U.S. Government's Federal Information Processing Standards
140 Level 2 rating.

         The Automatic Information product category also includes a group of
parts referred to as 1-Wire chips. These devices provide a unique electronic
identity and often store pertinent information about the product of which they
are a component. The data can be accessed externally or by the product itself.
The 1-Wire technology has the advantage of requiring the addition of just a
single connection point to access this data. It might be used in a cell phone
battery pack to indicate to the charger how to charge properly or in a toner
cartridge to fine tune the copier's print quality. Multiple 1-Wire chips can all
communicate on the same single wire, allowing the interconnection of many
devices to form a miniature LAN (MicroLAN). 1-Wire chips can perform a variety
of functions such as monitor temperature, measure voltage, control an acutator,
or blink a light.

         COMMERCIAL TIMEKEEPING. Accurate clock-calendar information remains in
demand in the ever evolving communications, consumer, industrial and medical
markets ("CCIM"). A comprehensive line-up of CCIM timekeepers from the Company,
including more than 45 base products in both chip and module packaging, are in
production to meet this need. Digital cellular phones utilize Serial Timekeepers
to provide advanced features such as clock-calendar display, talk-time, re-dial
timing and power management. Phantom and Watchdog modules are used in data
communications network routers, hubs and bridges to monitor communications
traffic and store the extensive amounts of network configuration data. Serial
Timekeepers and Bytewide Watchdog Timekeepers provide solutions in industrial
control and medical equipment applications requiring extended functions
including Nonvolatile SRAM and A/D conversion and temperature measurement.

         Many electronic systems gather and transmit time critical data. This
information ranges from banking transactions and internet data to remote sensing
and data logging. The time stamping of information between machines with
different Real Time Clocks ("RTC") can introduce errors between the systems.
Dallas Semiconductor has developed a 32 KHz Temperature Compensated Crystal
Oscillator ("TCXO"), which is used to drive the RTC crystal input. This TCXO
will enable the RTC to attain accuracies of +/-2PPM or 1 minutes/year over the
full temperature range of 0C to 40C. Previously, the best accuracy over the full
temperature range was +/-30 minutes per year. Higher frequency TCXO's to
address the accuracy requirements of markets like cellular phones, data logging
and T1/E1 telecom markets are in development.

         NONVOLATILE RAMS. Static random access memory ("SRAM") chips, which
were first introduced over 20 years ago, are used for high speed storage and
retrieval of data. SRAMs have always had the undesirable characteristic of data
loss when power is disrupted. Dallas Semiconductor has combined its circuitry
and understanding of ultra low power CMOS SRAMs with improvements in long life
lithium power sources to develop a family of Nonvolatile SRAM products.
Nonvolatile SRAMs integrate a lithium power source and intelligent control
circuitry to retain data even in the absence of system power. The control
circuit, by monitoring the level of system voltage available to the memory at
all times, switches to the lithium power source when necessary, and also
protects the memory contents against inadvertent changes during system power
fluctuations. A lithium power source provides backup power for more than 10
years in the absence of system power. Recent additions to the product line have
increased memory capacity, added features to the basic architecture, and offered
a solution for surface mount systems.

         MICROCONTROLLERS. A microcontroller typically combines a central
processing unit, data memory, program memory and input-output devices on a
single chip in order to control a wide variety of electronic systems. Dallas
Semiconductor offers two product categories of Microcontroller devices, both
based on the popular 8051 instruction set. The first, the Secure Microcontroller
category, is based on the concept of using battery-backed non-volatile SRAM to
hold program and data information. Unlike rigid ROM (read only memory) or EPROM
(electrically programmable ROM) based microcontrollers, all of Dallas
Semiconductor's Secure Microcontrollers are designed for change. By using
high-performance, read/write SRAM memory, software is easily modified and
remains nonvolatile for more than 10 years. This memory is initially loaded via
a serial port and can be dynamically allocated to fit program and data storage
requirements of a particular task. Unique security features of this product line
allow users to "lock" their software into the processor thereby protecting it
from unauthorized access and protecting valuable intellectual property. The
second product category of Microcontrollers is based on a completely redesigned
8051 core that executes the same instruction set up to three times faster with
no hardware changes. With this improved execution efficiency and because these
devices were designed to be pin-for-pin compatible, they offer users the unique
ability to add features and improve performance of their system without a
complete redesign.

         COMPUTER TIMEKEEPING. The personal computer has been the dominant
target market for computer timekeeping. This highly competitive market is
extremely cost sensitive and has seen increased use of chip sets with integrated
clock functions. The Company has differentiated Computer Timekeeping products by
adding NV SRAM, energy conservation components and Year 2000 compliance to
provide solutions in applications requiring enhanced features with higher levels
of integration.

         OTHERS. A description of some of the more significant categories
described as "Others" include the following.

         INTEGRATED BATTERY BACKUP. Nearly all electronic systems operate under
the control of one or more microprocessors (uP). The instructions for these uPs
or the data they use are subject to loss or corruption in the event of a power
outage. Power outages can be inadvertent or intentional, but in either case an
orderly transition to an alternate source of power is critical to retain
instructions or data held in random access memory (RAM). The Nonvolatile
Controller monitors the main power supply to the RAM in a system. In the event
of a power failure it switches the RAM over to an alternate source of power and
prevents any data loss or corruption.

         INTELLIGENT SOCKETS. Often, after a system's design is complete, the
manufacturer may desire to enhance functionality because of increased
competition from newer products. Dallas Semiconductor has incorporated active
electronics in sockets which can be soldered into a system board and add
capabilities without requiring substantive changes in the existing system. For
example, many systems manufacturers desire the capability to make SRAMs in
existing systems nonvolatile. In this instance, they can replace the SRAM's
socket in a system currently in use with a SmartSocket in the same place, and
plug the memory circuit into the SmartSocket. A lithium battery and control
circuit within the SmartSocket now allow the SRAM to retain data in the event of
a loss of system power. Another example is a requirement in many existing
systems to monitor and record time of day. The SmartWatch replaces standard SRAM
sockets in existing systems and adds the ability to keep time of day to
hundredths of a second while also making connected memory circuits nonvolatile.

         SILICON TIMED CIRCUITS. Electronic systems require exact timing to
control the transmission of data between their component parts. Timing
requirements vary across systems. Historically, systems designers have not been
able to use semiconductors as timing references because of their lack of
precision; they consequently achieved the required accuracy by using, in
combination or separately, quartz crystals and hybrid passive components, known
as delay lines. Dallas Semiconductor's all-silicon delay lines offer single chip
reliability, economy and high precision. Trimming to customer specifications
during the later stages of manufacturing provides precise accuracy and allows a
broad product mix without losing the economic benefits of standard integrated
circuit production. Customers are provided maximum flexibility, as well as the
option of purchasing tailor-made products at the approximate cost of standard,
off-the-shelf solutions. These all-silicon products can be designed into new
systems, as well as retrofitted into existing systems which otherwise utilize
hybrid approaches. Recently a family of low cost oscillators has been introduced
which apply delay-line-derived technology to solve other system timing
requirements.

MANUFACTURING

         The Company produces high performance CMOS integrated circuits with
sub-micron geometries at its own advanced wafer fabrication facility. This
facility processes six-inch wafers and utilizes an automated modular process
technology that provides substantial flexibility in the manufacturing process
and significantly reduces the number of persons required for operation. The
facility was physically expanded in 1989 and an additional wafer fabrication
facility module was completed in 1994. Additional equipment is installed from
time-to-time to support higher production volumes or advanced processing needs.
The Company's wafer fabrication facility increased its wafer production by
approximately 23% in 1998 and by approximately 18% in 1997. During fiscal 1998,
all of the wafers used by the Company were processed at its own facility. In
1998, the Company began using an outside foundry for the development of certain
products. The foundry is producing wafers used for research and development
("R&D") purposes and none of these products has reached production levels. A
separate bump fabrication facility was opened in September 1998 and will be
fully functional in the first quarter of 1999. The new facility will package the
Company's new and proprietary 1-Wire chips in a Chip-Scale Package. Using
flip-chip technology, a wafer-level solder bumping process produces a finished
circuit no bigger than the silicon die itself, meeting industry needs for low
cost, reduced size and simplified mounting.

         After silicon wafers have been fabricated, the Company utilizes
overseas assembly contractors to cut the wafers into individual chips and
assemble them into integrated circuit packaging. The Company performs module
assembly operations and final testing for a large majority of the Company's
products in Dallas, Texas. In 1999, the Company plans to further leverage the
utilization of offshore contractors by implementing the testing and modular
assembly of certain products in the Philippines.

PRODUCT COMPONENTS

         During fiscal 1998, the Company was able to obtain an adequate supply
of static memory circuits from multiple suppliers. These circuits are used in a
number of the Company's products. The Company anticipates that, at least for the
short term, an adequate supply of these memory circuits will be available;
however, given the historically unpredictable and undependable supply of these
components, shortages may recur causing future sales of some Company products to
be delayed or lost. If such shortages occur, future sales and earnings from
products using these circuits, primarily Nonvolatile SRAMs, could be adversely
affected. Additionally, any significant fluctuations in the purchase price for
these components could impact the Company's gross margins. The Company continues
to seek alternative sources for these components, including internal production
of static memory circuits for use in its own products, primarily the Nonvolatile
SRAMs.

SALES

         Sales are made to distributors and to OEMs. For fiscal 1998 no OEM
customer accounted for more than 5% of the Company's net sales, and the
Company's top 25 OEM customers accounted for approximately 26% of net sales. The
Company sells its products to customers by utilizing its own sales force and a
global network of independent sales representative firms and distributors.
During fiscal 1998, sales to domestic distributors represented approximately 35%
of the Company's net sales, with the Company's largest domestic distributor,
Avnet, accounting for a total of approximately 13% of net sales.

                                      -5-

<PAGE>   6


         Export sales accounted for 42% of net sales in fiscal 1998, including
19% and 23% in Europe and the Far East, respectively. The Company's export sales
are billed in United States dollars and, therefore, the Company's results of
operations are not subject to currency exchange adjustments. Although export
sales are subject to government export regulations, the Company has not
experienced any significant difficulties to date because of these regulations.

         The Company recognizes revenues from sales to distributors at the time
of shipment to the distributor. As is common in the semiconductor industry, the
Company grants price protection to distributors. Under this policy, distributors
are granted credits for the difference between the price they were originally
charged for products in inventory at the time of a price reduction and the
reduced price which the Company subsequently charges distributors. From time to
time, distributors are also granted credits on an individual basis for
Company-approved price reductions to specific customers made to meet
competition. The Company also grants distributors limited rights to return
products. The Company maintains reserves against which these credits and returns
are charged.

BACKLOG

         The Company's backlog, although useful for scheduling production, does
not represent actual sales and should not be used as a measure of future
revenues. Backlog orders are generally subject to cancellation without penalty
at the option of the purchaser and to changes in delivery schedules and do not
reflect adjustments made for price decreases passed on to distributors or
credits for returned products. As of January 3, 1999, the Company's backlog was
approximately $71 million, as compared to approximately $80 million at December
28, 1997. The Company includes in its backlog all released purchase orders
shippable within the next 12 months.

THE SEMICONDUCTOR INDUSTRY AND COMPETITION

         The semiconductor industry is characterized by rapid technological
change, intense competition from domestic and foreign competitors, cyclical
market patterns, price erosion, occasional shortages of materials, variations in
manufacturing yields and efficiencies and significant expenditures for capital
equipment and product development. The industry has from time to time
experienced severely depressed business conditions, as well as short term
softness and imbalances. The Company's future operating results may also be
affected by economic conditions in the United States and international markets,
such as the recent economic downturn in Southeast Asia and the outcome and
impact of the Year 2000. While the Company's strategy is designed to reduce its
exposure to these factors, fluctuations in operating results could occur due to
one or more of these factors. The available supply of certain memory circuits
used in a number of the Company's products has historically been unpredictable
and undependable. Shortages in the supply of these circuits could limit the
Company's future sales and earnings growth, and significant price fluctuations
in the purchase price for these circuits could impact the Company's gross
margins. See "Item 1. Business - Product Components."

         The Company faces competition from major domestic and international
integrated circuit manufacturers, many of which have substantially greater
manufacturing, financial, distributing and marketing resources than the Company,
as well as from emerging companies attempting to obtain a share of the existing
market. The Company competes principally on the basis of the quality, technical
innovation, functionality and timeliness of introduction of its products, the
adaptability of such products to specific applications, and price. The Company
believes that the early recognition of market opportunities and its willingness
to invest substantial time and capital in product development, coupled with
product complexity and diversity, constitute an important competitive advantage.
The Company's ability to compete successfully in the rapidly evolving
semiconductor industry depends on numerous factors, some of which are within the
Company's control and others of which are predominately outside of the Company's
control. These factors include general economic conditions, changes in
conditions affecting OEMs, competition, alternative technologies, the Company's
success in developing new products and process technologies, accelerated
declines in the average selling price of the Company's existing products,
changes in customer order patterns, market acceptance of the Company's new
products, distributor and sales representative performances, the ability of the
Company to continue diversifying its product line, accelerated growth of
inventory leading to excess inventory and salability and/or obsolescence
write-downs, excess production capacity, manufacturing performance,
subcontractor performance, availability and price fluctuations of components and
other raw materials, and other factors. Any of these uncertainties could cause a
severe near-term impact on the Company's order growth, net sales growth or
results of operations.

PATENTS AND INTELLECTUAL PROPERTIES

         Dallas Semiconductor has to date acquired or been granted 244 U.S.
patents and seven foreign patents. The expiration dates of the Company's patents
range from 1999 to 2015. None of the patents individually is considered material
to the Company's business. The Company has a number of patent applications
pending, although no assurance can be given that patents will ever be issued
from such applications or that any patents, if issued, will be determined to be
valid. The Company has also registered a number of its trademarks, as well as
the mask works for certain products, and has sought copyright protection for its
software and product literature. No assurance can be given, however, that such
protection will give the Company any material competitive advantage in the
semiconductor industry, due to the possibility of rapid technological
obsolescence of such patented products, trademarks, copyrights and registered
mask works, and the inherent limitations of the protection afforded under such
laws.

         The Company has been notified that it may be infringing certain patents
held by others. These notices are in various stages of evaluation. In the event
infringement is claimed and the Company believes that a license is necessary or
desirable, a license may be sought. The Company believes that if sought, a
license could be obtained on commercially reasonable terms, although no
assurance can be given in this regard.

ENVIRONMENTAL REGULATION

         The Company is subject to a variety of local, state and federal
governmental regulations in connection with emissions, the discharge of certain
chemicals during its manufacturing process and the handling and disposal of
various substances used in manufacturing. Failure to comply with present or
future regulations could result in the suspension or cessation of the Company's
operations. In addition, such regulations could in the future restrict the
Company's ability to expand at its present location or could require the Company
to acquire significant equipment or incur other substantial expenses.

YEAR 2000 READINESS DISCLOSURE

         In response to the "Year 2000 Information and Readiness Disclosure Act"
signed into law October 19, 1998, and the statement issued by the Securities and
Exchange Commission regarding "Disclosure of Year 2000 Issues and Consequences
by Public Companies, Investment Advisers, Investment Companies, and Municipal
Security Holders" in August 1998, the Company is making the following Year 2000
Readiness Disclosure:

         The Company has undertaken an assessment of all mission critical
systems, including information systems as well as production and manufacturing
systems, which could be significantly affected by Year 2000 issues. The Company
has initiated various Year 2000 remediation projects, some of which include the
use of software purchased from third parties. Some of this third party provided
software was modified by the Company to be compatible with its internal systems.
The Company has already begun testing and implementing these remediation
projects and anticipates substantial completion by March 31, 1999. Similarly,
certain hardware, primarily used in production and manufacturing systems, is
being replaced in a systematic manner. Replacement of this hardware was
originally scheduled due to anticipated obsolescence and is expected to be
substantially complete by June 30, 1999. As of December 31, 1998, the Company
has incurred approximately $125,000 in Year 2000 remediation costs and expects
to incur approximately $75,000 in remaining costs to ensure functionality for
Year 2000 issues. The Company has not specifically set aside funds to cover the
remaining Year 2000 costs, but has adequate resources to cover these needs as
they arise.

         None of the Company's systems interface directly with its third party
vendors. Also, the Company does not currently utilize electronic data
interchange (EDI) with any date sensitivity. In addition, the Company is
formally communicating by mailing letters to all of its significant third party
vendors (both domestic and international), requesting certifications and test
results to confirm their Year 2000 compliance. Where responses are not obtained
by letter, the Company is in the process of or will follow up to obtain this
information in an effort to limit the extent to which the Company may be
vulnerable to the failure of third parties to remediate their own Year 2000
issues. The Company also intends to mitigate this risk by ceasing to do business
with such companies as soon as feasible after it becomes aware of any
significant problems.

         The Company has two principal product lines containing products that
are date sensitive, Timekeeping and Microcontrollers.

         Timekeeping Products (Clocks) made by the Company fall into two
categories:

         o    Clocks that are Year 2000 compatible

         o    Clocks that are Year 2000 compliant

         Clocks that are Year 2000 compatible have a two-digit year counter.
They will maintain the correct time, date of the month, day of the week, month
and two-digit year with correct leap year compensation up to year 2099. The
two-digit year counter does not provide the century information; therefore
software intervention is required to determine if the century value is 19 or 20.

         The following Clocks are Year 2000 compatible, requiring software
intervention to calculate the century: DS1202, DS1215, DS1216, DS1243, DS1244,
DS1248, DS1251, DS1283, DS1284, DS1285, DS1286, DS1287, DS12885, DS12887,
DS12887A, DS12B887, DS1302, DS1305, DS1306, DS1307, DS1308, DS1315, DS1384,
DS1385, DS1386, DS1387, DS1395, DS1397, DS14285, DS14287, DS1485, DS1486,
DS1488, DS1495, DS1497, DS1543, DS1544, DS1546, DS1547, DS1615, DS1642, DS1643,
DS1644, DS1646, DS1647, DS1670, and DS1673.

         The Clocks that are Year 2000 compliant have a four-digit year counter.
The fully compliant clocks will maintain the correct time, date of the month,
day of the week, month and four-digit year with correct leap year compensation
up to year 2099.

         The following Clocks are fully Year 2000 compliant: DS12C887, DS1501,
DS1511, DS1553, DS1554, DS1546, DS1557, DS1585, DS1587, DS1589, DS1685, DS1687,
DS1688, DS1689, DS1691, DS1693, Ds17285, DS17287, DS1742, DS1743, DS1744,
DS1746, DS1747, DS17485, DS17487, DS17885, and DS17887.

         Microcontroller Products use one of three real-time clock circuits and
fall into one of two categories, compatible or compliant, as described above.

     DS 1215-based Soft Microcontroller Modules: DS5000T and DS2250T.

     The DS1215 is Year 2000 compatible, as it stores the year as a two-digit
     value. The two-digit year counter does not provide the century information;
     therefore software intervention is required to determine if the century
     value is 19 or 20.

     DS1283-based Soft Microcontroller Modules: DS2251T and DS22522T.

     The DS1283 is Year 2000 compatible, as it stores the year as a two-digit
     value. The two-digit year counter does not provide the century information;
     therefore software intervention is required to determine if the century
     value is 19 or 20.

     DS87C530 High Speed Microcontroller with Real Time Clock.

     The Clock in the DS87C530 incorporates a 16 bit day counter, rather than a
     traditional day/month/year calendar, for maximum flexibility. As a result,
     the device can be totally Year 2000 compatible via application software.

         The following are other Dallas Semiconductor products that are date
sensitive:

         The DS2404, DS1994, and DS1427, members of the Company's Automatic
Identification product category, contain simple binary counters and require
software intervention to interpret this raw data to be Year 2000 compliant.

         The DS1629, a member of the Company's System Extension product
category, incorporates a DS1307 real-time clock that has a two-digit year
counter. The two-digit year counter does not provide the century information;
therefore, software intervention is required to determine if the century value
is 19 or 20.

         All of the Company's products require the utilization of software
programs for the products to be of use to the end user. The Company does not
recommend or provide software for use in conjunction with any application for
the products it manufactures, including software solutions to Year 2000 issues.
However, to the extent practicable, purchasers of our Year 2000 compatible
products (which require software intervention) have been put on notice, via data
books and web page postings, of the need for such software intervention prior to
purchasing such products and further have been made aware of available Year 2000
alternatives (compliant products not requiring software intervention)
manufactured by the Company. Although the Company does not believe it has any
liability related to Year 2000 compatible products (those which require software
intervention), there is a risk of litigation associated with the manufacture and
sale of these products.

         Management of the Company believes it has an effective program in place
to resolve Year 2000 issues and expects that all critical remediation projects
will be completed on schedule. As a result of its focus on ensuring that the
remediation projects are on schedule, the Company has not developed a
contingency plan to address alternative solutions in the event the Company is
unable to successfully make its critical systems Year 2000 compliant. However,
the Company continually evaluates its status towards completion to determine
whether such a plan is necessary. At this point, the Company is on schedule and
no contingency plan is deemed necessary. Additionally, the Company has no means
of ensuring that third parties, including those based outside of the United
States, will be Year 2000 compliant and the effect of non-compliance by third
parties is not determinable. In a worst case scenario, these unknown third party
variables could have a material adverse effect on the Company's ability to
produce its products and conduct its business. This worst case scenario,
however, is a risk of any company engaging in world-wide business into the next
millennium. To date, the Company is not aware of any third party with a Year
2000 issue that would materially impact the Company's results of operations,
liquidity, or capital resources. In addition, the Company is not currently aware
of any claims of breach of contract or warranty, potential product return issues
or impairment of assets relating to Year 2000 noncompliance that would
materially impact the Company's results of operations, liquidity, or capital
resources.

EMPLOYEES

         At January 3, 1999 the Company had 1,530 employees. The Company
believes that its future success is dependent upon its ability to employ and
retain qualified technical and management personnel, particularly the highly
skilled design engineers involved in the development of new products. The
competition for such personnel is intense. During fiscal 1998, the Company
continued its practice of utilizing contract labor supplied by temporary
agencies, primarily in the manufacturing area. At January 3, 1999, the Company
was utilizing the services of 156 such temporary agency employees.

ITEM 2.  PROPERTIES

         The Company's headquarters are located in Dallas, Texas. As of January
3, 1999, the Company owned approximately 40 acres of land that includes
approximately 632,000 square feet of building space. The Company's property
provides space for administrative and engineering personnel, as well as wafer
fabrication, test and surface mount production areas, warehousing, distribution
facilities and assembly operations. The Company currently leases a total of
48,000 square feet of nearby building space for additional warehousing.

         The Company currently leases small office facilities for its sales
staff in Irvine, California, Sunnyvale, California, Woodland Hills, California,
Chelmsford, Massachusetts, Geneva, Illinois, Akron, Ohio, and Dallas, Texas,
under short term leases. The Company leases a small office facility in
Beaverton, Oregon, for design engineering. The Company's subsidiaries, Dallas
Semiconductor Corporation Limited, Dallas Semiconductor Corporation (Taiwan) and
Dallas Semiconductor Corporation (Germany), lease office facilities in
Birmingham, England, Taipei, Taiwan, and Munich, Germany, respectively. The
Company's foreign sales corporation operates out of Bridgetown, Barbados, W.I.

         Export sales accounted for 42% and 43% of total net sales in 1998 and
1997, respectively. Export sales to Europe and the Far East in 1998 were 19% and
23% of total sales, respectively.

         Cost of sales were $162.4 and $178.4 million in 1998 and 1997,
respectively. Gross margins increased to 52.6% in 1998 from 51.5% in 1997. The
increase in gross margins resulted primarily from increased efficiency in
factory operations and a sales-mix shift toward higher margin products.

         R&D expenses were $47.5 million and $46.1 million or 13.9% and 12.5% of
net sales in 1998 and 1997, respectively. Higher R&D expenses resulted primarily
from increased salaries and benefits. Increased R&D spending reflects the
Company's commitment to new product development as a means to increase future
revenues and to further diversify the Company's product offerings. The Company
introduced 34 new base products in 1998 compared with 25 new base product
introductions in 1997. Product introduction occurs when sample quantities of
product are shipped to one or more customers. The cumulative number of base
products introduced by the Company totaled 326 at fiscal year end 1998.

         Selling, general and administrative ("SG&A") expenses increased to
$56.5 million in 1998 from $53.8 million in 1997. SG&A expenses as a percent of
sales were 16.5% and 14.6% in 1998 and 1997, respectively. The increase is
primarily the result of increases in personnel costs due to increased headcount.

         Operating income in 1998 was $76.2 million, down 15.2% from $89.9
million in 1997. Operating income as a percentage of net sales (operating
margin) decreased to 22.2% in 1998 from 24.4% in 1997. The decrease resulted
primarily from the decrease in net sales and increased spending.

         Net interest income was $5.1 and $4.7 million in 1998 and 1997,
respectively. Net interest income increased primarily due to higher average cash
balances in 1998. Any substantial change in the Company's cash and short-term
investments and changes in interest rates will continue to affect net interest
income.

         The provision for income taxes was $25.9 million in 1998 and $30.0
million in 1997. The provision for income taxes consisted of estimated federal
and state income taxes at statutory rates and a deferred tax benefit of $1.0
million in 1998 and $6.2 million in 1997. The Company's effective tax rate
increased to 31.9% in 1998 from 31.7% in 1997 as a result of anticipated
differences between income for financial statement purposes and taxable income
for the two periods.

         A number of uncertainties exist that may influence the Company's future
operating decisions and results, including general economic conditions, changes
in conditions affecting original equipment manufacturers, competition,
alternative technologies, the Company's success in developing new products and
process technologies, accelerated declines in the average selling price of the
Company's existing products, changes in customer order patterns, market
acceptance of the Company's new products, distributor and sales representative
performances, the ability of the Company to continue diversifying its product
line, accelerated growth of inventory leading to excess inventory and salability
and/or obsolescence write-downs, excess production capacity, manufacturing
performance, subcontractor performance, availability and price fluctuations of
components and other raw materials, and other factors. Any of these
uncertainties could cause a severe near-term impact on the Company's order
growth, net sales growth or results of operations. Also, see the Company's Year
2000 Readiness Disclosure in Part 1 of this document.

1997 Results of Operations Compared with 1996

         Net sales in 1997 were $368.2 million, up 28% compared with $288.4
million in 1996. Net sales increases resulted from higher unit sales of new
and/or existing products in several product categories.

         Export sales accounted for 43% and 45% of total net sales in 1997 and
1996, respectively. Export sales to Europe and the Far East in 1997 were 20% and
23% of total sales, respectively.

         Cost of sales were $178.4 and $157.1 million in 1997 and 1996,
respectively. Gross margins increased to 51.5% in 1997 from 45.5% in 1996. The
increase in gross margins resulted primarily from increased efficiency in
factory operations and a sales-mix shift toward higher margin products.

         R&D expenses were $46.1 million and $35.0 million or 12.5% and 12.1% of
net sales in 1997 and 1996, respectively. Higher R&D expenses resulted primarily
from increased salaries and benefits. Increased R&D spending reflects the
Company's commitment to new product development as a means to increase future
revenues and to further diversify the Company's product offerings. The Company
introduced 25 new base products in 1997 compared with 21 new base product
introductions in 1996. The cumulative number of base products introduced by the
Company totaled 292 at fiscal year end 1997.

         SG&A expenses increased to $53.8 million in 1997 from $42.2 million in
1996. SG&A expenses as a percent of sales remained constant at 14.6%. The
increase consisted primarily of increased sales commissions to support higher
net sales and increased personnel costs.

         Operating income in 1997 was $89.9 million, up 66% from $54.1 million
in 1996. Operating income as a percentage of net sales (operating margin)
increased to 24.4% in 1997 from 18.8% in 1996. The increase resulted primarily
from the gross margin increase of 6.0%.

         Net interest income was $4.7 and $3.0 million in 1997 and 1996,
respectively. Net interest income increased primarily due to higher average cash
balances in 1997.

         The provision for income taxes was $30.0 million in 1997 and $18.7
million in 1996. The provision for income taxes consisted of estimated federal
and state income taxes at statutory rates and a deferred tax benefit of $6.2
million in 1997 and $0.7 million in 1996. The Company's effective tax rate
decreased to 31.7% in 1997 from 32.8% in 1996 as a result of the extension of
the federal research and development tax credit by the Taxpayer Relief Act of
1997 and anticipated differences between income for financial statement purposes
and taxable income for the two periods.

Financial Condition

         The Company's cash and short-term investments totaled $128.0 million at
January 3, 1999, compared to $114.6 million at December 28, 1997. The increase
in cash and short-term investments was primarily the result of net cash provided
from operations of $87.8 million, offset by investments in property, plant and
equipment of $76.0 million. The Company continues to invest in financial
instruments having maturities in excess of one year to obtain yields higher than
those available in the short-term market.

         The current ratio at fiscal year end 1998 increased to 5.7, compared
with 3.8 at fiscal year end 1997. The Company expects to fund its 1999 capital
needs primarily with cash flows from operations, supplemented where appropriate
with existing cash and short-term investments or external financing.

         Gross capital additions to property, plant and equipment in 1998
totaled $76.0 million, compared with $58.6 million in 1997. As of January 3,
1999, the Company owned approximately 632,000 square feet of building space and
40 acres of land in Dallas. Capital additions in 1998 included $27.2 million in
capital expenditures for wafer fabrication ("fab") equipment and $20.0 million
for manufacturing and test equipment.

         Capital expenditures in 1999 are anticipated to be $50 million and will
be used primarily for fabrication equipment, manufacturing and test equipment,
and computer hardware and software.

         In August 1994, the Board of Directors authorized the purchase from
time-to-time, depending on market conditions, of up to 500,000 shares of its
common stock. In December 1998, the Board of Directors increased this number by
an additional 500,000 shares. As of January 3, 1999, 232,800 shares at a
cumulative average price of $17.54, totaling $4,085,000, have been purchased
pursuant to this stock repurchase program and recorded using the cost method.

         Total dividends paid in 1998 were $0.16 per share or $4,482,000. On
January 26, 1999 the Board of Directors increased its annual cash dividend on
the Company's common stock from $0.16 to $0.20 per share. The board also
declared a quarterly cash dividend of $0.05 on each outstanding share of its
common stock, payable on March 1, 1999 to holders of record on February 15,
1999.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       THE COMPANY

         Dallas Semiconductor Corporation (the "Company") was incorporated in
Delaware in February 1984. The Company develops, manufactures and markets
high-performance complementary metal oxide silicon (CMOS) integrated circuits
and semiconductor-based systems that provide innovative and cost-effective
solutions to electronic design problems in a wide range of existing and emerging
markets.

         Export sales, principally to customers in Europe and the Far East,
represented approximately 42%, 43%, and 45% of net sales in 1998, 1997, and 1996
respectively. Sales to domestic distributors comprised approximately 35%, 34%,
and 31% of net sales in 1998, 1997, and 1996 respectively. In 1998, 1997 and
1996 one distributor accounted for $43,006,000 or 13%, $41,041,000 or 11%,
30,889,000 or 11% of net sales, respectively. No other distributor or original
equipment manufacturer ("OEM") customer accounted for 10% or more of net sales
in the years presented.

2.       SIGNIFICANT ACCOUNTING POLICIES

         Fiscal year. The Company operates on a 52- or 53-week fiscal year
ending on the Sunday nearest December 31. Fiscal year 1998, a 53-week year,
ended January 3, 1999. Fiscal years 1997 and 1996 ended December 28, 1997 and
December 29, 1996, respectively.

         Principles of consolidation. The consolidated financial statements
include the accounts of the Company and its subsidiaries. All significant
intercompany accounts and transactions have been eliminated.

         Cash and short-term investments. The Company classifies its cash
equivalents and short-term investments as current. Cash and short-term
investments consist of municipal bonds and money market funds and corporate
notes. At January 3, 1999 and December 28, 1997 cash and short-term investments
which had a maturity of greater than 90 days when purchased were $123,779,000
and $107,214,000, respectively. At January 3, 1999, $8,918,000 of the total
short-term investments is scheduled to mature within one year. Such investments
are carried at amounts which approximate their fair market value based on quoted
market prices. The Company places its investments only in high credit quality
financial instruments, and limits the amount invested in any one institution or
in one instrument.

         Inventories. Inventories are stated at the lower of standard cost,
which approximates actual cost (first-in, first-out), or market.

         Property, plant and equipment. Property, plant and equipment are stated
at cost. Depreciation is calculated based on the straight-line method over the
estimated useful lives of the related assets, generally forty years for
buildings, five to ten years on building improvements and two to nine years for
computer hardware, software, and machinery and equipment.

         Revenue recognition. Sales are recognized upon shipment to distributors
and to OEM customers. Sales to domestic distributors are made under distributor
agreements which provide the distributor certain price reduction and return and
allowance rights. Such sales are reduced for estimated future price reductions
and returns.

         Research and development. Research and development costs are charged to
operations when incurred.

         Income taxes. Taxes are reported under SFAS No. 109 and, accordingly,
deferred taxes are recognized using the liability method, whereby tax rates are
applied to cumulative temporary differences based on when and how they are
expected to affect the tax return. Deferred tax assets and liabilities are
adjusted for tax rate changes.

         Concentration of credit risk. The Company markets its products for sale
to OEMs and distributors primarily in the United States, Europe, and the Far
East. The Company performs ongoing credit evaluations of its customers and
generally does not require collateral. The Company maintains reserves for
potential credit losses and such losses have been within management's
expectations.

         Stock Options. Effective January 1, 1996, the Company adopted the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation", which requires pro forma disclosure of net income and net income
per share as if the SFAS No. 123 fair value method had been applied. As
permitted by SFAS No. 123, the Company continues to measure and recognize
compensation costs under the provisions of Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees".

         Segments. In June 1997, the FASB issued SFAS No. 131, "Disclosures
about Segments of an Enterprise and Related Information." SFAS 131 establishes
standards for reporting information in interim and annual financial statements
and is effective for fiscal years beginning after December 15, 1997. As the
Company operates predominantly in one industry segment, management believes it
is in compliance with the standards established by SFAS 131.

         Use of Estimates. The preparation of the consolidated financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the reported amounts of revenues and expenses during
the reporting period. Because of the use of estimates inherent in the financial
reporting process, actual results could differ from those estimates.

4.       STOCKHOLDERS' EQUITY

         Stock options. In August 1984, the Company adopted the 1984 Stock
Option Plan (the "1984 Plan") under which, as amended, an aggregate of 2,220,919
shares of common stock has been reserved for issuance. In February 1987, the
Company adopted the 1987 Stock Option Plan (the "1987 Plan") under which, as
amended, an aggregate of 5,947,339 shares of common stock has been reserved for
issuance. On April 23, 1996, the 1987 Plan was amended to provide for an annual
increase, on and as of January 1st of each calendar year, of 1% of the number of
shares of common stock outstanding on December 31st of the preceding year. Under
this 1987 Plan provision, 266,053, 275,483 and 282,248 shares were reserved for
issuance on January 1st 1996, 1997, and 1998, respectively. These shares are
reflected in the option table on the next page. All options have been granted at
no less than 100% of the fair market value of the stock on the date of grant. As
of January 3, 1999, the 1984 Plan had options outstanding at $6.25 with an
expiration date of January 21, 2001.

         In October 1998, 249,500 outstanding options from the 1987 Plan, with
exercise prices in excess of $23.75, were canceled and regranted at the then
market price of $23.75 per share. The new options maintain the vesting schedule
of the canceled options, except that these options cannot be exercised within
the following twelve months. As of January 3, 1999, the 1987 Plan had options
outstanding ranging from $4.50 to $23.75 with a weighted average exercise price
of $13.80 and expiration dates ranging from October 4, 1999 to December 15,
2008.

         Options generally are nontransferable and expire no later than ten
years from date of grant. Options generally are exercisable upon grant. Shares
of common stock issuable and/or exercised under the 1984 Plan and the 1987 Plan
vest based upon years of service, generally four years. Upon termination of a
participant's employment, the Company reserves the right to repurchase the
nonvested portion of the stock held by the employee, at the original option
price.

         Under SFAS No. 123, the Company is required to estimate the fair value
of each option on the date of the grant. The Company believes that the value of
unvested options is indeterminable by reason of the vagaries of the stock market
and other factors and opposes any requirement to place a value on an option
grant. However, to comply with the disclosure provisions of SFAS No. 123, the
Company used the Black-Scholes option pricing model to estimate the fair value
of each option at the date of grant. The following weighted-average assumptions
were used for 1998, 1997 and 1996: dividend yields of 0.40%, risk-free interest
rate of 6%, expected volatility of 40%, and expected lives of 6 years. The
weighted-average fair value per stock option granted in 1998, 1997 and 1996, as
defined by SFAS No. 123, was $12.01, $16.82 and $8.11, respectively. As of
January 3, 1999, the weighted average remaining contractual life of the options
is 5.8 years.

         The effects on pro forma disclosures of applying SFAS No. 123 are not
likely to be representative of the effects on pro forma disclosures of future
years, since it is applicable only to options granted subsequent to December 31,
1995. If compensation cost for the Company's stock-based compensation plans had
been determined in accordance with SFAS No. 123, the Company's net income and
net income per share would have been reduced to the pro forma amounts shown in
the following table.

listed in the Index at Item 14(a). These consolidated financial statements and
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements and schedule
based on our audits.

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

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Dallas Semiconductor Corporation and subsidiaries as of January 3, 1999 and
December 28, 1997, and the consolidated results of its operations and its cash
flows for each of the three fiscal years in the period ended January 3, 1999, in
conformity with generally accepted accounting principles. Also, in our opinion,
the related financial statement schedule, when considered in relation to the
basic financial statements taken as a whole, presents fairly in all material
respects the information set forth therein.

                                                           /s/ Ernst & Young LLP

                  the Plan must file a written claim with the Plan
                  Administrator. All such claims shall be submitted on a form
                  provided by the Plan Administrator which shall be signed by
                  the claimant and shall be considered filed on the date the
                  claim is received by the Plan Administrator. The claim will be
                  processed by the Plan Administrator in accordance with its
                  uniform policies. The Plan Administrator shall notify the
                  Participant or Beneficiary in writing, within ninety (90) days
                  of his written application for benefits, of his or her
                  eligibility or noneligibility for benefits under the Plan. If
                  the Plan Administrator determines that the Participant or
                  Beneficiary is not eligible for benefits or full benefits, the
                  notice shall set forth (1) the specific reasons for such
                  denial, (2) a specific reference to the provisions of the Plan
                  on which the denial is based, (3) a description of any

                  and other appropriate information as to the steps to be taken
                  if the beneficiary wishes to have the claim reviewed. If the
                  Plan Administrator determines that there are special
                  




<PAGE>   8



                  circumstances requiring additional time to make a decision,
                  the Plan Administrator shall notify the Participant or
                  Beneficiary of the special circumstances and the date by which
                  a decision is expected to be made, and may extend the time for
                  up to an additional ninety-day (90) period.

         2.9            REVIEW PROCEDURES. If the Participant or Beneficiary is
                  determined by the Plan Administrator not to be eligible for
                  benefits, or if the Participant or Beneficiary believes that
                  he or she is entitled to greater or different benefits, the
                  Participant or Beneficiary shall have the opportunity to have
                  such claim reviewed by the Plan Administrator by filing a
                  petition for review with the Plan Administrator within sixty
                  (60) days after receipt of the notice issued by the Plan
                  Administrator. Said petition shall state the specific reasons
                  which the Participant or Beneficiary believes entitle him or
                  her to benefits or to greater or different benefits. Within
                  sixty (60) days after receipt by the Plan Administrator of the
                  petition, the Plan Administrator shall afford the Participant
                  or Beneficiary (and counsel, if any) an opportunity to present
                  his or her position to the Plan Administrator orally or in
                  writing, and the Participant or Beneficiary (or counsel) shall
                  have the right to review the pertinent documents. The Plan
                  Administrator shall notify the Participant or Beneficiary of
                  its decision in writing within the sixty (60) day period,
                  stating specifically the basis of its decision, written in a
                  manner calculated to be understood by the Participant or
                  Beneficiary and the specific provisions of the Plan on which
                  the decision is based. If, because of the need for a hearing,
                  the sixty (60) day period is not sufficient, the decision may
                  be deferred for up to another sixty (60) day period at the
                  election of the Plan Administrator, with notice of this
                  deferral given to the Participant or Beneficiary.

                  as amended ("Code") on the Company's ability to deduct such

         4.2            INVESTMENT OF ACCOUNTS.  Only Units may be credited to
                  a Participant's Account.

                  Trust shall be invested as provided in the Trust. Units equal
                  in number to the value of Dividends received shall be
                  allocated pro rata as of the date received among only the
                  Accounts of Participants employed by the Company on the date
                  the Dividend was received by multiplying (i) a fraction, the
                  numerator of which is each such Participant's Units allocated
                  to his Account and the denominator of which is all such
                  Participants' Units allocated to their Accounts by (ii) the
                  total Units representing the value of the Dividend received.

5        UNITS.

         5.1            ALLOCATION OF UNITS. The number of Units initially 
                  allocated to each Participant's Account shall be the Units
                  designated for that Participant on Appendix A. Subsequent
                  contributions by the Company after the Contribution shall be
                  allocated pro rata as of the date received among only the
                  Accounts of Participants employed on the date the subsequent
                  contribution was received by multiplying (i) the total Units
                  representing the contribution received by (ii) a fraction, the
                  numerator of which is each such Participant's Units allocated
                  to his Account and the denominator of which is all of the
                  Units allocated to all such Participants' Accounts.

                  Account shall be immediately vested.

                  If at any time while the Plan is in effect or Units are
                  otherwise outstanding there shall be any increase or decrease
                  in the number of issued and outstanding shares of Stock
                  through the declaration of a stock dividend or through any
                  recapitalization resulting in a stock split-up, combination or
                  exchange of shares of Stock, an appropriate adjustment shall
                  be made in the number of each Participant's Units then
                  outstanding so that immediately after such event his Units
                  shall continue to bear the same proportionate relationship to
                  the shares of Stock then issued and outstanding as such Units
                  bore to the number of outstanding shares of Stock immediately
                  prior to such event; provided, however, that the issuance of
                  shares of Stock or of shares of the Company's capital stock of
                  any class, or securities convertible into shares of Stock or
                  shares of capital stock of any class, either in connection
                  with direct sale or upon the exercise of rights or warrants to
                  subscribe or upon conversion of shares or obligations
                  convertible into such shares or other 




<PAGE>   10



                  securities, shall not affect, and no adjustment by reason of
                  such activity shall be made with respect to, the Units
                  outstanding on the date of such event(s). Without limiting the
                  generality of the foregoing, the existence of Units shall not
                  affect in any manner the right or power of the Company to
                  make, authorize or consummate (i) any or all adjustments,
                  recapitalizations, reorganizations or other changes in the
                  Company's capital structure or its business; (ii) any merger
                  or consolidation of the Company; (iii) any issue by the
                  Company of debt securities, or preferred or preference stock
                  which would rank above the shares of Stock; (iv) the
                  dissolution or liquidation of the Company, (v) any sale,
                  transfer or assignment of all or any part of the assets or
                  business of the Company; or (vi) any other corporate act or
                  proceeding, whether of a similar character or otherwise.

6        DISTRIBUTION OF ACCOUNTS

         6.1            PAYMENT OF DISTRIBUTION. Subject to PARAGRAPH 6.4, each
                  Participant shall be entitled to receive a distribution of his
                  Account when the Realization Date occurs and not earlier. A
                  Participant entitled to a distribution under this Paragraph
                  shall be paid at the time designated in PARAGRAPH 6.4.

         6.2            AMOUNT DISTRIBUTABLE. The amount distributable from his
                  Account to a Participant who was employed on the Realization
                  Date (or had retired from the Company prior to the Realization
                  Date) shall be the product of: (i) the fair market value of
                  the Stock held in the Trust on the Realization Date,
                  determined after subtracting the fair market value of any
                  remaining Units allocated to Participants who Terminated prior
                  to the Realization Date, multiplied by (ii) a fraction, where
                  the numerator is the number of Units in the Participant's
                  Account and the denominator is the total number of Units in
                  all Accounts of Participants who were employed on the
                  Realization Date (or had retired from the Company prior to the
                  Realization Date).

         6.3      Notwithstanding the preceding, in the event a Participant 
                  Terminates prior to the Realization Date, the Value of the
                  Units distributable to that Participant from his Account as
                  his Severance Distribution shall be the Participant's share of
                  the Contribution credited to his Account pursuant to Paragraph
                  4.1, reduced by his proportionate share of the net decline in
                  fair market value of the Stock held in the Trust between the
                  Effective Date and the date of his Termination, and shall in
                  no event exceed the Participant's share of the Contribution.
                  After a Severance Distribution, the Units held for such
                  Participant shall be canceled, and the excess shares of Stock
                  initially purchased in the Trust to measure the Plan's
                  obligation to the Participant shall be sold as provided in
                  PARAGRAPH 6.5.

         6.4            FORM OF DISTRIBUTION. Distribution of a Participant's 
                  Account shall be only in a single lump sum cash payment equal
                  to the Participant's amount distributable. The Committee may,
                  in its sole discretion, make payments under this Paragraph net
                  of applicable federal and state withholding taxes.

         6.5            TIMING OF DISTRIBUTION. Distribution of a Participant's
                  Account shall occur on or after January 1, 2005 but not later
                  than March 15, 2005; provided, however, that (i) if a
                  Participant Terminates because of his death, distribution
                  shall occur as soon as reasonably possible after the
                  Participant died and his Beneficiary has been determined, and
                  (ii) if a Change of Control occurs where the Realization Date
                  becomes the date the Change of Control occurred, distribution
                  shall occur on the Realization Date.

         6.6            FORFEITURES. In the event a Participant receives his 
                  Severance Distribution, the balance in his Account after
                  deducting the value of the Severance Distribution shall be
                  immediately forfeited. Sufficient shares of Stock in the Trust
                  equal in value to the value of the forfeiture, if any, shall
                  be immediately sold, and the sale proceeds returned to the
                  Company immediately after sale.

7        BENEFICIARIES

         7.1            BENEFICIARY DESIGNATION. Each Participant may 
                  designate a Beneficiary or Beneficiaries to receive any
                  payments which such Participant is entitled to receive under
                  the terms of the Plan in the event he dies prior to receiving
                  the full amount of such payments. Such designation may be made
                  at any time by filing a Beneficiary designation form with the
                  Committee prior to the date of his death and may be changed by
                  filing a new Beneficiary designation form with the Committee
                  prior to the date of his death. If any Participant dies after
                  properly filing a Beneficiary designation form, all payments
                  shall be distributed as provided in such Beneficiary
                  designation form. All amounts to be paid to a Beneficiary
                  under this Paragraph shall be paid in the same manner as such
                  payments would have been paid to the Participant had he or she
                  survived.

         7.2            ABSENCE OF BENEFICIARY DESIGNATION. If any Participant
                  dies without having properly filed a Beneficiary designation
                  form, or if the Participant does not, in the sole discretion
                  of the Committee, have a valid, proper Beneficiary
                  designation, all payments shall be made to his or her
                  surviving spouse, or in the absence of a surviving spouse,
                  then to his estate.

8        FUNDING

         8.1            IN GENERAL. Any obligation of the Company to pay 
                  benefits under the Plan shall be an unsecured promise, and any
                  right to enforce such obligation shall be solely as a general
                  creditor of the Company. For the convenience and benefit of
                  the Company and to the extent not inconsistent with the
                  foregoing sentence, the Company may establish one or more
                  revocable or irrevocable trusts to hold assets to meet its
                  obligations under the Plan to Participants.

         8.2            TRUST ASSETS. The property comprising the assets of a 
                  Trust established under PARAGRAPH 8.1 shall, at all times,
                  remain the property of the Trust. The Trustee shall distribute
                  the assets comprising the Trust in accordance with the



<PAGE>   12




                  provisions of the Plan and Trust as instructed by the
                  Committee, but in no event shall the Trustee distribute (i)
                  one or more shares of Stock or (ii) the assets of the Trust to
                  or for the benefit of the Company, except as provided in the
                  Trust in the case of insolvency or bankruptcy of the Company
                  or after satisfaction of all the Company's obligations under
                  the Plan to the Participants.

9        AMENDMENT AND TERMINATION

         9.1            AMENDMENT OF THE PLAN. The Committee shall have the 
                  power (and, without limitation, may delegate some or all of
                  such power to any officer) to amend the Plan, retroactively or
                  otherwise, in any manner in which it deems desirable.

         9.2            COMPANY ACTION. Any action required of the Company 
                  shall be evidenced by a resolution of the Board or shall be
                  taken by a person authorized to act by a duly adopted
                  resolution of the Board.

         9.3            TERMINATION OF THE PLAN.  The Committee reserves the 
                  right at any time, in its sole discretion, to terminate this
                  Plan in whole or in part.

10       MISCELLANEOUS

         10.1           RIGHTS AGAINST THE COMPANY. Neither the establishment 
                  of the Plan nor any amendment of the Plan, nor the
                  participation in the Plan, nor the payment of any benefits
                  under the Plan, (i) shall be construed as giving to any
                  Participant or any other person any legal or equitable rights,
                  except as are set forth in the Plan, against the Company or
                  its officers or directors, as such, (ii) shall be construed as
                  giving any Participant the right to be retained as an employee
                  and (iii) shall prejudice the Company's rights to discharge or
                  discipline any employee for any reason.

         10.2           EXPENSES OF ADMINISTRATION.  All expenses incident to 
                  the administration of the Plan shall be paid by the Company.

         10.3           NOTICE TO THE COMPANY.  Any notice, request, or demand,
                  which by any provision of this Plan is required or permitted
                  to be given or served to the Plan Administrator shall be
                  deemed to be sufficiently given and served for all purposes by
                  being personally delivered or sent by certified mail to the
                  place of business of the Company.

         10.4           APPLICABLE LAW.  The Plan will be construed and 
                  enforced according to the laws of the State of Texas, and all
                  provisions of the Plan will be administered according to the
                  laws of the said state.

         10.5           PROVISIONS FOR SOLE BENEFIT OF PARTIES. All of the 
                  covenants, stipulations and agreements in this Plan contained
                  are, and shall be, for the sole and exclusive 


<PAGE>   13



                  benefit of, and are binding upon, the parties to this Plan,
                  their successors and assigns, and the Participants in the
                  Plan.

         10.6           PARAGRAPH HEADINGS.  The titles or headings of the 
                  respective Paragraphs in the Plan are inserted merely for
                  convenience and shall be given no legal effect.

         10.7           SEVERABILITY. In the event any provision of the Plan 
                  shall be held to be illegal or invalid for any reason, the
                  illegality or invalidity shall not affect the remaining
                  provisions of the Plan, but shall be fully severable, and the
                  Plan shall be construed and enforced as if the illegal or
                  invalid provision had never been included in the Plan.

         10.8           BINDING ARBITRATION. In the event of any claim or 
                  controversy arising out of or relating to this Plan, the
                  parties agree that all such claims or controversies shall be
                  resolved by final and binding arbitration in Dallas County,
                  Texas in accordance with the Commercial Arbitration Rules of
                  the American Arbitration Association in effect on the date
                  when the claim or controversy first arises. Either party must
                  communicate its request for arbitration under this Paragraph
                  in writing ("Arbitration Notice") to the other party within
                  one hundred twenty (120) days from the date the claim or
                  controversy first arises. Failure to communicate the
                  Arbitration Notice within one hundred twenty (120) days shall
                  constitute a waiver of any such claim or controversy. All
                  claims or controversies subject to arbitration under this
                  Paragraph shall be submitted to an arbitration hearing within
                  ninety (90) days from the date Arbitration Notice is
                  communicated by either party. All claims or controversies
                  submitted to arbitration under this Paragraph shall be
                  resolved by a panel of three (3) arbitrators who are licensed
                  to practice law in the State of Texas and who are experienced
                  in the arbitration of employment disputes. These arbitrators
                  shall be selected in accordance with the applicable Commercial
                  Arbitration Rules or by agreement of the parties. Either party
                  may request that the arbitration proceeding be
                  stenographically recorded by a Certified Shorthand Reporter.
                  The arbitrators shall issue a decision on any claim or
                  controversy within thirty (30) days from the date the
                  arbitration hearing is completed, and such decision shall be
                  final and binding on all parties. The parties shall have the
                  right to be represented by legal counsel at any arbitration
                  hearing. The costs of any arbitration hearing, including the
                  attorneys' fees incurred by both parties (including any costs,
                  expenses or attorneys' fees incurred in filing any lawsuit to
                  compel arbitration, if applicable), shall be paid by the
                  losing party or parties. The arbitration provisions in this
                  Paragraph are subject to the Federal Arbitration Act, 9 U.S.C.
                  Sections 1 et seq. (West 1994) (or any successor provisions)
                  and may be specifically enforced by any party, and submission
                  to arbitration proceedings may be compelled by any court of
                  competent jurisdiction. The decision of the arbitrators may be
                  specifically enforced by any party in any court of competent
                  jurisdiction.

         10.9           NO ASSIGNMENT. The rights of a Participant to payment
                  under this Plan shall not be assigned, transferred, pledged or
                  encumbered, either voluntarily or by 




<PAGE>   14



                  operation of law, except as provided in PARAGRAPH 7.1 with
                  respect to designation of Beneficiaries. If any person shall
                  attempt to assign, transfer, pledge or encumber any amount
                  payable under the Plan, or if by reason of his Bankruptcy or
                  other event happening at any time any such payment would be
                  made subject to his debts or liabilities or would otherwise
                  devolve upon anyone else and not be enjoyed by him or his
                  Beneficiary, the Plan Administrator may, in its sole
                  discretion, terminate such person's interest in any such
                  payment and direct that the same be held and applied to, or
                  for the benefit of, such person, his spouse or dependents, in
                  such manner as the Plan Administrator may deem proper.

         IN WITNESS WHEREOF, this Plan has been executed by the Chairman of the
Board, President and Chief Executive Officer of the Company this 11th day June,
1998, but effective as of the Effective Date.

                        DALLAS SEMICONDUCTOR CORPORATION
                   EXECUTIVE DEFERRED COMPENSATION PLAN TRUST


         This Agreement made this 11th day of June, 1998 by and between Dallas
Semiconductor Corporation ("Company") and Wells Fargo Bank, N.A. ("Trustee").


         WHEREAS, Company wishes to establish a trust (hereinafter called
"Trust") and to contribute to the Trust assets that shall be held therein,
subject to the claims of Company's creditors in the event of Company's
Insolvency, as herein defined, until paid to Plan participants and their
beneficiaries in such manner and at such times as specified in the Dallas
Semiconductor Corporation Executive Deferred Compensation Plan ("Plan");

         WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement for tax purposes and shall not affect the
status of the Plan as an unfunded plan maintained for the purpose of providing
deferred compensation for a select group of management or highly compensated
employees for purposes of Title I of the Employee Retirement Income Security
Act of 1974; and

         WHEREAS, it is the intention of Company to make contributions to the
Trust to provide itself with a source of funds to assist in the meeting of its
liabilities under the Plan.

         NOW, THEREFORE, the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:


         Section 1. Establishment of Trust.

         (a) Company hereby deposits with Trustee in trust Two Million Two
Hundred Forty Thousand Dollars ($2,240,000) (the "Contribution") which shall
become the principal of the Trust to be held, administered and disposed of by
Trustee as provided in this Trust Agreement.

         (b) The Trust hereby established shall be irrevocable.

         (c) The Trust is intended to be a grantor trust, of which Company is
the grantor, within the meaning of subpart E, part I, Subchapter J, chapter 1,
subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

         (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of Company and shall be used exclusively
for the uses and purposes of Plan participants and general creditors as herein
set forth. Plan participants and their beneficiaries shall have no preferred
claim on, or any beneficial ownership interest in, any assets of the Trust. Any
rights created under the Plan and this Trust Agreement shall be mere unsecured
contractual rights of Plan participants and their beneficiaries against
Company. Any 



<PAGE>   2
assets held by the Trust will be subject to the claims of Company's general
creditors under federal and state law in the event of Insolvency, as defined in
Section 3(a) herein.

         (e) Company, in its sole discretion, may at any time, or from time to
time, make additional deposits of cash or other property in trust with Trustee
to augment the principal to be held, administered and disposed of by Trustee as
provided in this Trust Agreement. Neither Trustee nor any Plan participant or
beneficiary shall have any right to compel such additional deposits.


         Section 2. Payments to Plan Participants and Their Beneficiaries.

         (a) Company shall deliver to Trustee a schedule (the "Payment
Schedule") that indicates the amounts payable in respect of each Plan
participant (and his or her beneficiaries), the form in which such amount is to
be paid (as provided for or available under the Plan), and the time of
commencement for payment of such amounts. Except as otherwise provided herein,
Trustee shall make payments to the Plan participants and their beneficiaries in
accordance with such Payment Schedule. The Trustee shall make provision for the
reporting and withholding of any federal, state or local taxes that may be
required to be withheld with respect to the payment of benefits pursuant to the
terms of the Plan and shall pay amounts withheld to the appropriate taxing
authorities or determine that such amounts have been reported, withheld and
paid by Company. The Company shall provide the Trustee with such other
information as may be reasonably requested by the Trustee in order to allow the
Trustee to comply with all of its distribution, reporting and withholding
responsibilities hereunder.

         (b) The entitlement of a Plan participant or his or her beneficiaries
to benefits under the Plan shall be determined by Company or such party as it
shall designate under the Plan, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plan.

         (c) Company may make payment of benefits directly to Plan participants
or their beneficiaries as they become due under the terms of the Plan. Company
shall notify Trustee of its decision to make payment of benefits directly prior
to the time amounts are payable to participants or their beneficiaries. In
addition, if the principal of the Trust, and any earnings thereon, are not
sufficient to make payments of benefits in accordance with the terms of the
Plan, Company shall make the balance of each such payment as it falls due.
Trustee shall notify Company where principal and earnings are not sufficient.

         Section 3. Trustee Responsibility Regarding Payments to Trust
Beneficiary When Company Is Insolvent.

         (a) Trustee shall cease payment of benefits to Plan participants and
their beneficiaries if the Company is Insolvent. Company shall be considered
"Insolvent" for purposes of this Trust Agreement if (i) Company is unable to
pay its debts as they become due, or (ii) Company is subject to a pending
proceeding as a debtor under the United States Bankruptcy Code.

         (b) At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of Company under federal and state law as set forth
below.

                  (1) The Board of Directors and the Chief Executive Officer of
         Company shall have the duty to inform Trustee in writing of Company's
         Insolvency. If a person claiming to be a creditor of Company alleges
         in writing to Trustee that Company has become Insolvent, Trustee shall
         determine whether Company is Insolvent and, pending such
         determination, Trustee shall discontinue payment of benefits to Plan
         participants or their beneficiaries.

                  (2) Unless Trustee has actual knowledge of Company's
         Insolvency, or has received notice from Company or a person claiming
         to be a creditor alleging that Company is Insolvent, Trustee shall
         have no duty to inquire whether Company is Insolvent. Trustee may in
         all events rely on such evidence concerning Company's solvency as may
         be furnished to Trustee and that provides Trustee with a reasonable
         basis for making a determination concerning Company's solvency.

                  (3) If at any time Trustee has determined that Company is
         Insolvent, Trustee shall discontinue payments to Plan participants or
         their beneficiaries and shall hold the assets of the Trust for the
         benefit of Company's general creditors. Nothing in this Trust
         Agreement shall in any way diminish any rights of Plan participants of
         their beneficiaries to pursue their rights as general creditors of
         Company with respect to benefits due under the Plan or otherwise.

                  (4) Trustee shall resume the payment of benefits to Plan
         participants or their beneficiaries in accordance with Section 2 of
         this Trust Agreement only after Trustee has determined that Company is
         not Insolvent (or is no longer Insolvent).

         (c) Provided that there were sufficient assets, if Trustee
discontinues the payment of benefits from the Trust pursuant to Section 3(b)
hereof and subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
participants or their beneficiaries under the terms of the Plan for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
participants or their beneficiaries by Company in lieu of the payments provided
for hereunder during any such period of discontinuance.

         Section 4. Payments to Company.

         Except as provided in Section 3 hereof, after the Trust has become
irrevocable, Company shall have no right or power to direct Trustee to return
to Company or to divert to others any of the Trust assets before all payment of
benefits have been made to Plan participants and their beneficiaries pursuant
to the terms of the Plan.


         Section 5. Investment Authority.

         (a) Subject to Company's rights under Section 5(d), and subject
further to Section 5(e), Trustee shall invest all contributions solely in
Company's authorized common stock, $.02 par value ("Company Stock"), within ten
(10) trading days after receipt or, if necessary to prevent unusual
fluctuations in the Company Stock's price, as soon as reasonably possible after
receipt. Subject to Sections 5(d) and 5(e), Trustee shall hold the shares of
Company Stock so acquired until January 1, 2005. Company Stock shall be sold to
fund benefit payments under the Plan as needed and shall be sold only as needed
to fund benefit payments under the Plan or to return forfeitures to the Company
under the Plan. All purchases of Company Stock shall be made on the open market
at fair market value. Until invested in Company Stock, all contributions and
income that are not needed for current expenditures shall be held in
interest-bearing investments under Section 5(b)(4) pending the investment of
such funds in Company Stock.

         (b) Subject to the provisions of Section 5(a), 5(d) and 5(e), Trustee
shall have the following investment powers:

                  (1) To invest in any properties, real or personal or mixed,
         including but not limited to, common or preferred stocks (including
         Company Stock or rights to acquire Company Stock), securities, or any
         other interest in any corporation, interests in investment trusts and
         mutual funds, bonds, notes or other evidences of indebtedness or
         ownership, first mortgages, real property, leases on real property,
         contracts to sell real property, contracts of sale of real property,
         short-term cash equivalents having ready marketability, including but
         not limited to U.S. Treasury bills, commercial paper, certificates of
         deposit, savings shares or savings share accounts of savings and loan
         associations, and similar type securities, and any other property of
         any kind or nature whatsoever;

                  (2) To purchase or subscribe for property and to retain it as
         a Trust asset; to sell any Trust asset at any time held by it at
         either public or private sale for cash or other consideration or on
         credit at such time or times and on such terms and conditions as may
         be deemed appropriate; to exchange such Trust assets and to grant
         options for the purchase or exchange thereof; and to convey,
         partition, or otherwise dispose of,


                                       4
<PAGE>   5

         with or without covenants, including covenants of warranty of title, 
         any property free of all trusts;

                  (3) To register any property held by it hereunder in the name
         of Trustee or in the names of nominees with or without the addition of
         words indicating that such property is held in a fiduciary capacity,
         to take and hold the same unregistered or in form permitting
         transferability by delivery, to deposit or arrange for the deposit of
         securities in a qualified central depository even though, when so
         deposited, such property may be held in the name of the nominee of
         such depository with other securities deposited therein by other
         persons, or to deposit or to arrange for the deposit of any property
         issued by the United States government, or any agency or
         instrumentality thereof, with a Federal Reserve bank, provided that
         the books and records of Trustee shall at all times disclose that all
         such property is a Trust asset;

                  (4) To invest cash balances held by Trustee, from time to
         time, in short-term cash equivalents having ready marketability,
         including but not limited to money market mutual funds (including
         those for which Trustee or its affiliate act as investment advisor),
         U.S. Treasury bills, commercial paper, certificates of deposit,
         savings shares or savings share accounts of savings and loan
         associations, and similar type securities;

                  (5) Generally to do all such acts, to make, execute,
         acknowledge, and deliver any and all deeds, leases, assignments, oil
         and gas leases, documents of transfer, and conveyances, receipts,
         releases, agreements, and without limitation by the foregoing, to
         execute any and all other instruments, take all such proceedings and
         exercise all such rights and powers with relation to any Trust asset
         to the same extent as an individual might do with respect to his own
         property; and

                  (6) To deposit all or any Trust assets with a custodian,
         subject to the direction and control of the Trustee.

         (c) Subject to Section 5(a) and Section 5(e), Trustee may invest in
securities (including stock or rights to acquire stock) or obligations issued
by Company. All rights associated with assets of the Trust shall be exercised
by Trustee or the person designated by Trustee, and shall in no event be
exercisable by or rest with Plan participants.

         (d) Company shall have the right at anytime, and from time to time in
its sole discretion, to substitute assets of equal fair market value for any
asset held by the Trust. This right is exercisable by Company in a nonfiduciary
capacity without the approval or consent of any person in a fiduciary capacity.

         (e) Company shall have full investment responsibility for the
purchase, sale, retention, tender and voting of Company Stock and for any
insurance contracts, and Trustee shall act with respect to Company Stock and
any insurance contracts only as provided in this Section or as otherwise
directed by Company.

         During the term of this Trust, all income received by the Trust, net
of expenses and taxes, shall be accumulated and reinvested as provided in
Section 5.


         Section 7. Accounting by Trustee.

         Trustee shall keep accurate and detailed records of all investments,
receipts, disbursements, and all other transactions required to be made,
including such specific records as shall be agreed upon in writing between

administration of the Trust during such quarter or during the period from the
close of the last preceding quarter to the date of such removal or resignation,
setting forth all investments, receipts, disbursements and other transactions

purchased and sold with the cost or net proceeds of such purchases or sales
(accrued interest paid or receivable being shown separately), and showing all
cash, securities and other property held in the Trust at the end of such
quarter or as of the date of such removal or resignation, as the case may be.


         Section 8. Responsibility of Trustee.

         (a) Trustee shall act with the care, skill, prudence and diligence
under the circumstances then prevailing that a prudent person acting in like
capacity and familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims, provided, however, that
Trustee shall incur no liability to any person for any action taken pursuant to
a direction, request or approval given by Company which is contemplated by, and
in conformity with, the terms of this Trust and is given in writing by Company.
In the event of a dispute between Company and a party, Trustee may apply to a
court of competent jurisdiction to resolve the dispute. In the event of a
conflict between the terms of the Trust and the terms of the Plan solely with
respect to the Trustee's obligations, the terms of the Trust shall take
precedence to the extent consistent with applicable law.

         (b) If Trustee undertakes or defends any litigation arising in
connection with this Trust, Company agrees to indemnify Trustee against
Trustee's costs, expenses and liabilities (including, without limitation,
attorneys' fees and expenses) relating thereto and to be primarily liable for
such payments. If Company does not pay such costs, expenses and liabilities in
a reasonably timely manner, Trustee may obtain payment from the Trust.

         (c) Trustee shall have, without exclusion, all powers conferred on
Trustees by applicable law, unless expressly provided otherwise herein;
provided, however, that if an insurance policy is held as an asset of the
Trust, Trustee shall have no power to name a 



                                       6
<PAGE>   7

beneficiary of the policy other than the Trust, to assign the policy (as
distinct from conversion of the policy to a different form) other than to a
successor Trustee, or to loan to any person the proceeds of any borrowing
against such policy.

         (d) Notwithstanding any powers granted to Trustee pursuant to this
Trust Agreement or to applicable law, Trustee shall not have any power that
could give this Trust the objective of carrying on a business and dividing the
gains therefrom, within the meaning of section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.


         Section 9. Compensation and Expenses of Trustee.

         Company shall pay all administrative and Trustee's fees and expenses.
If not so paid, the fees and expenses shall be paid from the Trust.


         Section 10. Resignation and Removal of Trustee.

shall be effective thirty (30) days after receipt of such notice unless Company
and Trustee agree otherwise.

         (b) Trustee may be removed by Company on thirty (30) days notice or 
upon shorter notice accepted by Trustee.

         (c) If Trustee resigns or is removed within four (4) years of a Change
of Control, as defined herein, Company shall apply to a court of competent
jurisdiction for the appointment of a successor Trustee or for instructions.

         (d) Upon resignation or removal of Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the
successor Trustee. The transfer shall be completed within fifteen (15) days
after receipt of notice of resignation, removal or transfer, unless Company
extends the time limit, which extension Company will not unreasonably withhold.

         (e) If Trustee resigns or is removed, a successor shall be appointed,
in accordance with Section 11 hereof, by the effective date of resignation or
removal under paragraph (a) or (b) of this section. If no such appointment has
been made, Trustee may apply to a court of competent jurisdiction for
appointment of a successor or for instructions. All expenses of Trustee in
connection with the proceeding shall be allowed as administrative expenses of
the Trust.

         Section 11. Appointment of Successor.

         (a) If Trustee resigns or is removed in accordance with Section 10(a)
or (b) hereof, Company may appoint any third party, such as a bank trust
department or other party that may be granted corporate trustee powers under
state law, as a successor to replace Trustee upon resignation or removal. The
appointment shall be effective when accepted in writing by the new Trustee, who
shall have all of the rights and powers of the former Trustee, including
ownership rights in the Trust assets. The former Trustee shall execute any
instrument necessary or reasonably required by Company or the successor Trustee
to evidence the transfer.

         (b) If Trustee resigns or is removed pursuant to the provisions of
Section 10(c) hereof, the appointment of a successor Trustee shall be effective
when accepted in writing by the new Trustee. The new Trustee shall have all the
rights and powers of the former Trustee, including ownership rights in Trust
assets. The former Trustee shall execute any instrument necessary or reasonably
requested by the successor Trustee to evidence the transfer.

         (c) The successor Trustee need not examine the records and acts of any
prior Trustee and may retain or dispose of existing Trust assets, subject to
Sections 5, 7, and 8 hereof. The successor Trustee shall not be responsible for
and Company shall indemnity and defend the successor Trustee from any claim or
liability resulting from any action or inaction of any prior Trustee or from
any other past event, or any condition existing at the time it becomes
successor Trustee.


         Section 12. Amendment or Termination.

         (a) This Trust Agreement may be amended by a written instrument
executed by Trustee and Company. Notwithstanding the foregoing, no such
amendment shall conflict with the terms of the Plan or shall make the Trust
revocable after it has become irrevocable in accordance with Section 1(b)
hereof.

         (b) The Trust shall not terminate until the date on which Plan
participants and their beneficiaries are no longer entitled to benefits
pursuant to the terms of the Plan, unless sooner revoked in accordance with
Section 12(c) hereof. Upon termination of the Trust any assets remaining in the
Trust shall be returned to Company.

         (c) Upon written approval of participants or beneficiaries entitled to
payment of benefits pursuant to the terms of the Plan, Company may terminate
this Trust prior to the time all benefit payments under the Plan have been
made. All assets in the Trust at termination shall be returned to Company.

this Trust Agreement may not be amended by Company for four (4) years following
