                                     PART I

ITEM 1.  BUSINESS

GENERAL

  Siliconix designs, markets, and manufactures power and analog semiconductor 
products.  The Company focuses on technologies and products for the 
communications, computer, and automotive markets; additionally, many of the 
Company's products are also used in instrumentation and industrial 
applications.

  Founded in 1962, Siliconix uses its advanced technology and applications 
expertise to develop value-added products for power management and 
conversion. These products serve two types of markets.  The first type, 
represented by the communications and computer markets, exhibits design 
cycles as short as a few months and product life cycles as short as six to 
twelve months, thus creating numerous new opportunities for the Company.  The 
other type, represented by the automotive market, exhibits long design 
cycles, sometimes as much as four or five years, and product life cycles as 
long or longer.  Participation in both types of businesses helps the Company 
balance growth opportunities with research and development investments 
required to maintain technology leadership.

  Siliconix was a member of TEMIC Semiconductors, a division of the 
Daimler-Benz microelectronics consortium, for several years. On December 16, 
1997, Daimler-Benz announced that it had agreed to sell the Semiconductor 
Division of TEMIC, which included its 80.4% interest in Siliconix, to Vishay 
Intertechnology, Inc. ("Vishay") of Malvern, Pennsylvania.  The acquisition 
was completed on March 2, 1998, and on that date, Vishay became the Company's 
largest shareholder.  The Company's products will continue to be marketed 
with the Siliconix brand name under the Vishay umbrella.

  Coincident with the acquisition of the majority interest in Siliconix by 
Vishay, Richard J. Kulle stepped down as Siliconix President and CEO and was 
replaced by Dr. King Owyang, formerly Executive Vice President, Technology & 
Silicon Operations.  Dr. Owyang has been employed by Siliconix for ten years 
and served in his previous position for approximately six years. From the 
beginning of his employment, Dr. Owyang led the technology advances which are 
the foundation of Siliconix's growth and profitability.

PRODUCTS

  All of the analog and power products produced by Siliconix can be divided 
into two general classes:  discrete devices and integrated circuits (ICs). 
Discrete devices are active components that generate, control, regulate, 
amplify, or switch electronic signals or energy.  They must be interconnected 
with other, passive components (E.G., resistors, capacitors, inductors, etc.) 
to create an electronic circuit.  ICs consist of a number of active and 
passive components, interconnected on a single chip, that are intended to 
perform a specific function.

  The Company's discrete power MOSFETs (an acronym for "metal oxide 
semiconductor field effect transistor") and power ICs are designed for 
similar applications and can often be used together as chip sets with 
complementary performance characteristics optimized for a specific 
application.

  Power MOSFETs are the Company's fastest growing products in terms of sales. 
In this product line, Siliconix has focused on low-voltage products that are 
prevalent in battery-operated products (E.G., notebook computers and cellular 
phones) and in automotive systems.  Siliconix has maintained technology 
leadership in low-voltage, surface-mount power MOSFETs through advances in 
both silicon technologies and product packaging.  Advanced silicon process 
technologies, such as the Company's "Trench" technology, offer very high cell 
densities and low device on-resistance.  These process technologies have been 
coupled with innovative packaging techniques to create surface-mount product 
families, such as LITTLE FOOT-Registered Trademark- power MOSFETs, that 


                                                                             2

<PAGE>

provide customers with size and performance benefits as well as manufacturing 
compatibility with digital integrated circuits.

  Siliconix power ICs include power conversion and interface ICs, and motor 
control ICs.  The Company's power conversion and interface ICs are based on 
low-voltage, mixed-signal silicon processes that offer customers higher 
frequencies and greater efficiencies than competitive products.  They are 
used in applications where an input voltage from a battery or other supply 
source must be switched or converted to a level that is compatible with logic 
signals used by microprocessors and other digital components in the system.  
The Company's motor control ICs are used to control motion in data storage 
applications (E.G., optical and hard disk drives) and to control the speed of 
small motors in office equipment (E.G., printers and copy machines).

  The Company's mature product lines include discrete small-signal 
transistors and signal processing ICs (I.E., analog switches and 
multiplexers).  The small-signal transistors range from junction field-effect 
transistors ("JFETs"), Siliconix's original product line, which remain critical
for some applications, to newer transistor processes, such as the Company's 
lateral DMOS process, which offer performance advantages over competitors' 
similar product lines. The analog switches and multiplexers are primarily 
used in instrumentation and industrial equipment that receives and/or outputs 
real-world analog signals.

   The following table shows net sales and the percentage of the Company's 
net sales attributable to the product categories for the periods indicated 
(dollars in thousands).

MANUFACTURING

  The Company's manufacturing operations are strategically located to support 
customer manufacturing locations, to cultivate growth markets, and to access 
cost-effective engineering talent. All of the Company's manufacturing sites 
use Statistical Process Control methods of total quality control and have ISO 
9000 certification.

  Siliconix fabricates wafers for its advanced power products at its Santa 
Clara, California manufacturing headquarters, where the Company maintains a 
Class 1 (clean room classification) six-inch wafer fab. Further capacity for 
wafer fabrication of power products was added during 1997 in a Class 1 
facility in Itzehoe, Germany. Wafers for analog switches and multiplexers are 
fabricated in the Company's four-inch wafer fab in Santa Clara. In 1997, 
fabrication of the Company's JFETs was transferred to a foundry in Beijing, 
China.

  Assembly and testing of the Company's products are performed in Company 
facilities in Taiwan and Shanghai, China, and by subcontractors in the 
Philippines and India.  The Shanghai facility is a joint venture between 
Siliconix and the Shanghai Institute of Metallurgy.

  Raw materials used by the Company include single-crystal silicon wafers, 
chemicals, gases, metal wire, and ceramic, plastic, and glass-to-metal 
packages.  Although these materials are generally available from two or more 


                                                                             3

<PAGE>

sources, the industry has experienced difficulties in obtaining supplies of 
some raw materials from time to time; such difficulties in the future could 
adversely affect the Company's operations.

  Government regulations impose various environmental controls on the 
discharge of certain chemicals and gases used in the manufacturing process.  
The Company believes that its activities substantially conform to present and 
anticipated regulations and is constantly upgrading its Santa Clara facility 
to ensure continued compliance with such regulations.  In 1990, the Company 
reached a settlement for cleanup of soil and groundwater at a site the 
Company occupied prior to 1972, with the current owner of that site, and 
settled a lawsuit against its insurance carriers in 1992 and 1993 with 
respect to this matter. The Company also established a remedial activity to 
remove soil and groundwater contamination at its Santa Clara site in 1990.  
For details on these matters, see Item 3, Legal Proceedings.  While the 
Company has experienced only limited effects on its operations from 
environmental regulations, there can be no assurance that changes in such 
regulations will not impose the need for additional capital equipment or 
other requirements.

SALES

  From 1993 until the change of ownership, Siliconix sales were handled by 
the sales organization of TEMIC Semiconductors, the semiconductor division of 
the Daimler-Benz microelectronics group, which included Siliconix, Telefunken 
Semiconductors, Matra MHS, and Dialog Semiconductor.  Unifying the sales 
activities for these four companies brought value to customers by allowing 
them to deal with one entity for a broader range of their semiconductor 
needs. Today, the Company's products are sold by the Vishay worldwide sales 
organization, which consists of much of the same worldwide structure of sales 
representatives and distributors that was established for TEMIC 
Semiconductors.

  The sales organizations are regionally based, functioning as agents that 
earn a commission at a fixed percentage of sales and performing all 
sales-related activities.  The following table shows net sales and the 
percentage of the Company's net sales on a geographic basis for the periods 
indicated (dollars in thousands).

</TABLE>

  In 1997, a Japanese distributor accounted for 10% of the Company's net 
sales. The Company markets its products in different geographic areas as 
follows.

  NORTH AMERICA:  Sales are made by the North American field sales force and 
manufacturer's representative organizations, the latter being compensated by 
commissions only.  Area sales managers coordinate these representatives and 
the North American sales force. North American sales offices are located in 
or near Santa Clara, California; Troy, Michigan; Basking Ridge, New Jersey; 
and Dallas, Texas.

  Sales not made directly to original equipment manufacturers are made 
through distributors, which currently have approximately 200 locations 
throughout the United States and Canada. Certain distributors are provided 
with contractual protection for their inventory against reductions in 
published prices and against product obsolescence.


                                                                             4

<PAGE>

  EUROPE:  Sales are made by the European sales force and manufacturer's 
representative organizations.  As in North America, sales not made directly 
to the original equipment manufacturers are made through distributors, with 
approximately 30 locations.  The distributors are provided with certain 
inventory obsolescence and price protections similar to those granted to 
domestic distributors.

  JAPAN:  Sales in Japan are made by the Asia Pacific sales force.

  ASIA PACIFIC:  Sales are made in Hong Kong, Korea, Taiwan, The People's 
Republic of China, and in Southeast Asia by the Asia Pacific sales force, 
headquartered in Singapore.  In these locations, as in the United States, 
sales are made directly to original equipment manufacturers through field 
sales engineers or through manufacturer's representatives.  Direct sales 
agents and representatives are compensated by commissions only.

  Sales in the rest of the world are made through manufacturer's 
representatives, stocking representatives, and distributors.

  For further information, see Note 7 of Notes to Consolidated Financial 
Statements, which is incorporated herein by reference.

ORDER BACKLOG

  As of December 31, 1997, the backlog of orders booked was $74.1 million.  
The backlog as of December 31, 1996 was $77.2 million.  The Company includes 
in backlog only open orders which have been released by the customer for 
shipment in the calendar year 1998.  The Company's customers encounter 
uncertain and changing demand for their products.  They typically order 
products from the Company based on their forecasts.  If demand falls below 
customers' forecasts, or if customers do not control their inventory 
effectively, they may cancel or reschedule their shipments previously ordered 
from the Company, in many instances without the payment of any penalty.  
Therefore, backlog is not necessarily indicative of sales for any future 
period.

COMPETITION

  The semiconductor industry is highly competitive.  Many of the Company's 
competitors are larger companies with greater financial resources and limited 
dependency on semiconductor products as their sole source of sales and 
earnings.  The Company has been able to compete effectively by being 
selective in its choice of products and markets, and by being a technology 
leader in those areas.  Through closely established customer relationships, 
the Company acquires in-depth applications know-how for the markets it serves 
and develops products that specifically address customer needs.

RESEARCH AND DEVELOPMENT

  Research and development activities are directed toward expanding 
technology leadership.  Focus is on developing new products and processes, 
and activities are ongoing to improve the cycle time from new product 
development to product release.  Total expenditures were $17.8 million in 
1997, $20.8 million in 1996, and $19.1 million in 1995.  Significant effort 
has been expended on new power products and ICs where continued rapid market 
growth is expected.


                                                                             5

<PAGE>

PATENTS AND LICENSES

  Siliconix protects its technology leadership by securing patents on 
proprietary products and processes.  As of December 31, 1997, Siliconix owned 
130 U.S. patents, covering primarily semiconductor device structures, 
processes, and circuitry.  Expiration dates for these patents range from 1998 
to 2016.  An additional eight patents have been allowed but not yet issued. 
There were also 64 U.S. patent applications pending.  The Company believes 
that, as it increasingly utilizes these patents in the design and manufacture 
of its products, its royalty obligations will decrease significantly.  See 
Note 8 of Notes to Consolidated Financial Statements.

EMPLOYEES

  In the last three years, the total number of employees has remained 
relatively flat, with only key positions focused on target growth areas being 
added.  On December 31, 1997, the Company employed 1,266 people, of whom 847 
were employed in the United States, 402 in East Asia, and 17 in Europe.

   There are no collective bargaining agreements between the Company and its 
employees, and there have been no work stoppages due to labor difficulties. 
The Company considers its relations with its employees to be excellent.

ITEM 3. LEGAL PROCEEDINGS.

  The Company is party to two environmental proceedings.  The first 
involved property that the Company vacated in 1972.  In July 1989, the 
California Regional Water Quality Control Board ("RWQCB") issued Cleanup and 
Abatement Order No. 89-115 both to the Company and the current owner of the 
property.  The Order alleged that the Company contaminated both the soil and 
the groundwater on the property by the improper disposal of certain chemical 
solvents.  The RWQCB considered both parties to be liable for the 
contamination and sought to have them decontaminate the site to acceptable 
levels.  The Company subsequently reached a settlement of this matter with 
the current owner of the property.  The settlement also provided that the 
current owner will indemnify the Company and its employees, officers, and 
directors against any liability that may arise out of any governmental agency 
actions brought for environmental cleanup of the subject site, including 
liability arising out of RWQCB Order No. 89-115, to which the Company remains 
nominally subject.

  The second proceeding involves the Company's Santa Clara, California 
facility, which the Company has owned and occupied since 1969.  In February 
1989, the RWQCB issued Cleanup and Abatement Order No. 89-27 to the Company. 
The Order is based on the discovery of contamination of both the soil and the 
groundwater on the property by certain chemical solvents.  The Order calls 
for the Company to specify and implement interim remedial actions and to 
evaluate final remedial alternatives.  The RWQCB issued a subsequent order 
requiring the Company to complete the decontamination.  The Company is 
complying with the RWQCB's orders.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

  As of March 20, 1998, there were 770 holders of record of the Company's 
Common Stock.  Under Delaware law, the Company may pay dividends only from 
retained earnings or, if none, from net profits for the current or preceding 
fiscal year.  The Company has paid no dividends since December 1980 in order 
to retain the Company's earnings to fund future growth requirements.  No 
change in such policy is anticipated in the near future.

  A presentation of the highest and lowest "last trade" price for the 
Company's Common Stock for each quarterly period during 1996 and 1997 is 
incorporated by reference from the Company's 1997 Annual Report to

Company's Common Stock trades on the Nasdaq Stock Market under the symbol

Independent Auditors' Report

Board of Directors
Siliconix incorporated:

  We have audited the accompanying consolidated balance sheets of Siliconix 
incorporated as of December 31, 1997 and 1996, and the related consolidated 
statements of operations, shareholders' equity, and cash flows for each of 
the years in the three-year period ended December 31, 1997.  These 
consolidated financial statements are the responsibility of the Company's 
management.  Our responsibility is to express an opinion on these 
consolidated financial statements 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 financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
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 financial position of Siliconix 
incorporated as of December 31, 1997 and 1996, and the results of their 
operations and their cash flows for each of the years in the three-year 
period ended December 31, 1997, in conformity with generally accepted 
accounting principles.

                      EMPLOYMENT AGREEMENT


     THIS AGREEMENT is entered into by and between JOHN COX (hereinafter 
referred to as "Employee") and SILICONIX INCORPORATED, a Delaware corporation 
(hereinafter referred to as the "Company"), on the 1st day of April, 1997.

     In consideration of the mutual obligations herein contained, the parties 
hereto hereby agree as follows:

     1. EMPLOYMENT.  The Company hereby agrees to employ Employee and 
Employee agrees to be employed by the Company upon the terms and conditions 
hereinafter set forth.

     2. TERM.

          2.1  The initial term of employment under this Agreement shall be 
three years, commencing on April 1, 1997 and ending on March 31, 2000.  In 
the event that neither party notifies the other of its intention not to 
extend this Agreement prior to January 31 of each year, starting in 1998, the 
term of this Agreement shall be automatically extended for one year.  This 
process shall continue until (i) such notice is timely given, in which case 
the Agreement shall terminate on the March 31 that is 26 months after the 
January 31 next occurring after said notice shall have been given or (ii) a 
new employment agreement is executed by the parties.

          2.2  Prior to the expiration of this Agreement, the Company has the 
right to terminate the employment of Employee for cause by delivering to him 
written notice specifying such cause, at which time its obligations under 
this Agreement will cease.  "Cause" means:

          (1)  Misappropriating any funds or property of (a) the Company, or 
               (b) any employee of the Company, or (c) any corporation 
               affiliated with the Company, or (d) any employee of any 
               corporation affiliated with the Company, or (e) any customer;

          (2)  Attempting to obtain any personal profit from any transaction 
               in which Employee has an interest which is adverse to the 
               interest of the Company, unless Employee has first obtained 
               the consent of management and approval of the Chairman of the 
               Board of the Company;

          (3)  Conviction of a felony; or

<PAGE>

          (4)  Breach of any material provision of this Agreement.


          2.3  If the Company should terminate Employee's employment for a 
reason not specified in this Agreement, Employee's final check will include 
an amount covering his salary for the period ending on the date on which this 
Agreement would otherwise have terminated.

     3. COMPENSATION.

          3.1  The Company agrees to pay Employee at the rate of $1,500 per 
day in accordance with its usual payroll practices.  Employee shall advise 
the Company in accordance with its usual payroll practices as to his days 
worked.

          3.2  Employee shall be entitled to participate, as long as he is an 
employee of the Company, in any and all of the Company's present or future 
employee benefit plans; provided, however, that the provisions of any such 
plan permit Employee's participation, after considering the number of hours 
per week that Employee works for the Company.

          3.3  The Company shall reimburse Employee for all expenses 
reasonably and necessarily incurred by Employee in the performance of his 
duties hereunder, including but not limited to Employee's transportation and 
lodging expenses relating to travel to Santa Clara, California from his home 
in Massachusetts and the international travel referred to in section 4.2 
hereof.

     4. DUTIES.

          4.1  Employee agrees to serve the Company and the Company agrees to 
employ Employee in the capacity of Vice President, Worldwide Environmental, 
Health & Safety Affairs.  The Company and Employee acknowledge and agree that 
Employee will be a part-time employee of the Company, working that number of 
days per month as shall be mutually agreed upon from time to time by Employee 
and the President of the Company, but no fewer than ten (10) calendar days 
per month, which shall consist of five to seven days on assignments away from 
Massachusetts and three to five days on assignments in Massachusetts.  
Employee agrees that at all times during his employment by the Company he 
will faithfully and diligently endeavor to promote the business and business 
interests of the Company.

          4.2  Employee acknowledges and agrees that as a part of his duties, 
at least one international trip in each of Q2, Q3 and

mutually agreed by the President of the Company and Employee, but shall be

Manila; and Bangalore, India.

     5. COMPANY AUTOMOBILE.  The Company agrees to provide Employee

Company's usual policies.  The Company shall be responsible for maintenance, 
insurance and gasoline for said automobile.

     6. TRADE SECRETS.

          6.1  Employee recognizes that the nature of his employment by the 
Company is such that he will have access to and that there will be disclosed 
to him during the course of his employment, information of a proprietary 
nature owned by the Company including but not limited to records, data, 
formulae, specifications, inventions, processes, methods and customer lists, 
which are of a confidential information or trade secret nature, and all of 
which have great value to the Company and are a substantial basis and 
foundation upon which the Company's business is predicated. Employee 
acknowledges that except for his employment and the duties assigned to him 
which he will be fulfilling, that he would not otherwise have access to the 
foregoing information.  Employee agrees that any and all confidential 
knowledge or information which may be obtained by him in the course of his 
employment, including but not limited to, the information hereinabove set 
forth, will be held inviolate by him and that he will conceal the same from 
any and all other persons, including but not limited to, competitors of the 
Company, and that he will not impart any such knowledge acquired by him as an 
employee of the Company to any such other persons either during his 
employment or after his employment by the Company has terminated.

          6.2  Employee agrees that upon termination of his employment 
hereunder he will immediately surrender and turn over to the Company all 
books, records, forms, specifications, formulae, data, processes, customer 
lists and all papers and writing relating to the business of the Company and 
all other property belonging to the Company, it being understood and agreed 
that the same are the sole property of the Company and that Employee will not

designs, improvements, inventions and other things of value that relate to 
the Company's business (hereinafter collectively referred to as "intangible 
rights"), whether patentable or not, which are conceived, made, invented or 
suggested either by him alone or in collaboration with others affiliated with 
the Company during the term of his employment, and whether or not during 
regular working hours, shall be promptly disclosed in writing to the Company 
and shall be the sole and exclusive property of the Company.  Employee hereby 
assigns all of his right, title and interest in and to all such intangible 
rights to the Company, its successors or assigns.  In the event that any of 
said intangible rights shall be deemed by Employee to be patentable or 
otherwise registerable under any federal, state or foreign law, Employee 
further agrees at the expense of the Company to execute all documents and to 
do all things necessary, advisable or proper to obtain patents or 
registration and to vest the Company with full title thereto.

     8. ARBITRATION.  Any dispute, controversy or claim arising under or in 
connection with this Agreement, or the breach thereof, shall be settled 
exclusively by arbitration in accordance with the Commercial Arbitration 
Rules of the American Arbitration Association then in effect.  Judgment upon

communication shall be deemed to have been given as of the date so deposited 
in the United States mail or as of the date delivered if delivered in person.

     10. INTEGRATED AGREEMENT.  This Agreement constitutes the entire 
agreement between the parties hereto relating to the employment of Employee, 
and there are no agreements or understandings relating to the subject matter 
hereof between the parties other than those set forth herein or herein

more counterparts, each of which shall be deemed an original, but all of

Management's Discussion and Analysis of Financial Condition and Results of 
Operations

Overview

     Siliconix (the "Company") is engaged in designing, manufacturing, and 
marketing power and analog semiconductor products. The Company is organized 
into three business units: Power MOSFET, Power IC, and Signal Processing. 
Power MOSFET is the producer of low-voltage, surface-mount Power MOSFET 
products primarily used for the communication, computer, and automotive 
markets.  Power IC  focuses on Power Integrated Circuits used in 
communication and data storage applications.  Signal Processing manufactures 
a wide array of commodity products such as Analog Switches, Low Power 
MOSFETs, and JFETs for industrial and consumer markets.

     The Company's 1997 results represent the eighth consecutive year of 
record revenues and the fourth consecutive year of record earnings.  Fiscal 
1997 net income of $33.0 million represents a growth of 27% and 36% over 
fiscal 1996 and fiscal 1995, respectively.

     During 1997, the Company responded to the increasing demand for  Power 
MOSFET products by starting a new six-inch wafer fabrication facility ("FAB") 
in Itzehoe, Germany.  The FAB, leased by TEMIC Semiconductor GmbH, a German 
corporation and related party, is operated and managed by the Company (see 
Note 2 of Notes to Consolidated Financial Statements).

     The Company further expanded its product offering in surface mount Power 
MOSFET products during 1997 and increased  this business by 27%.  This 
increase was driven by strong demand for the Company's  proprietary 
TrenchFETs-Registered Trademark- for the worldwide communication and computer 
markets. These market segments are subject to demand fluctuations which may 
adversely impact the Company's future business performance.

     Subsequent to year end, the 80.4% interest in Siliconix owned by 
Daimler-Benz was sold to a wholly-owned subsidiary of Vishay Intertechnology, 
Inc. ("Vishay") of Malvern, Pennsylvania.  The Company's products will 
continue to be marketed with the Siliconix brand name under the Vishay 
umbrella.

Revenues

     Fiscal 1997 revenue of  $321.6 million increased 20% over 1996 and 28% 
over 1995.  This growth is attributable to the strong demand for the 
Company's Power MOSFET LITTLE FOOT product family used primarily in power 
management of portable communication and computer equipment. These market 
segments showed strong bookings during the first three quarters of fiscal 
1997; however, during the fourth quarter of 1997, bookings slowed down due to 
market uncertainties.  This slowdown in bookings resulted in a decline in 
backlog by the end of the fourth quarter of 1997 and will impact revenues 
negatively in at least the first quarter of 1998 in comparison to the fourth 
quarter of 1997 and perhaps thereafter. In addition, it appears that earnings 
per share in the first quarter of 1998 will decline sharply in comparison to 
the fourth quarter and first quarter of 1997.

     Revenues for the commodity product lines increased 6% during 1997 to 
$74.6 million despite significant price erosion, especially for Low Power 
MOSFETs. Revenues for these commodity products are expected to remain flat 
during 1998 due to the maturity of the product offering.

     The Company operates in all major geographic regions of the 
semiconductor industry.   The following is a summary of the Company's revenue 
by region:

<TABLE>

Asia Pacific   26%            21%             24%
</TABLE>


<PAGE>

     During 1997, revenues in all regions, except Japan, experienced strong 
year to year growth.  Asia Pacific was the fastest growing region with a 48% 
revenue increase over 1996 and 40% increase over 1995.    Europe had revenue 
growth of 26% and 39% over 1996 and 1995, respectively.  North America 
experienced a revenue increase of  27% over 1996 and 22% over 1995.  The 
growth in these regions was driven by the communication and portable computer 
markets. Japan experienced a decline in revenues of 35% from 1996 and an 
increase in revenues of 4% over 1995.  The decline in Japan during 1997 is 
attributable to substantial price pressure from local competitors due to 
leveraging of underutilized DRAM capacities for the production of Power 
MOSFET products and the prolonged weakness of the yen against the dollar 
throughout 1997.  The Company does not anticipate any change in the 
competitiveness of the Japanese market during 1998.

Gross Profit

     Gross profit as a percentage of net sales was 40% in 1997 and 1996, and 
39% in 1995. The Company continued to face substantial price pressures 
worldwide during 1997, especially in Japan.   A strong U.S. dollar against 
all Asian and European currencies contributed to this pressure, especially in 
the last half of 1997.  The Company also incurred start-up expenses of  $9.2 
million for the FAB in Itzehoe, Germany.  The Company was able to fully 
offset these effects through introduction of new leading edge products, its 
large-scale manufacturing content in low cost countries, a strong technology 
position, and economies of scale.

     During 1997, the Company executed its strategy of increasing capacity 
for its planar Power MOSFET technology through the FAB in Germany, while 
increasing the production volume for its proprietary Trench and BICDMOS 
technologies by 88% over 1996. This increase in production volume was 
realized by capital investments in additional capacity and, more importantly, 
by utilizing higher cell density TrenchFET technology to further reduce 
die size by up to 30%, yielding more output and cost reductions. The Company 
was also able to reduce mask steps in various manufacturing processes 
resulting in further cost reductions.

     The Company continued its strategy of a strong manufacturing presence in 
various low cost locations in Asia during 1997. The Company successfully 
transferred its JFET wafer production from its four-inch wafer fab in Santa 
Clara to a third-party foundry in Beijing, China.  The Company will continue 
to produce the remaining processes in the four-inch fab until a suitable 
alternative is identified.

     Royalty expense as a percentage of revenues declined slightly during the 
last three years as the Company continues to shift new products to its 
proprietary technologies. This trend is expected to continue during 1998 and 
beyond.

Research and Development

     Research and development expenses decreased 14% in 1997 to $17.8 million 
compared to $20.8 million in 1996 and $19.1 million in 1995. This decrease 
was due to agreements in which the Company was reimbursed for certain 
expenses by a related party (see Note 2 of Notes to Consolidated Financial 
Statements). Additionally, there was a reduction in spending during 1997 due 
to cost controls.  Research and development expense is expected to increase 
in 1998 from 1997 as the Company continues to commit significant resources to 
the further development of higher cell density TrenchFET technology.

Selling, Marketing, and Administration

     Selling, marketing, and administration expenses increased 20% over last 
year to $65.3 million as  compared to $54.5 million  in 1996 and $50.3 
million in 1995. The increase in 1997 of $10.8 million was 


<PAGE>

driven by an increased focus on key customer account management, primarily in 
the marketing and sales functions, as well as overall employee retention 
programs in the highly competitive California job market.

    Interest expense for 1997 remained flat at $2.4 million compared to 1996, 
as short-term market rates have not fluctuated significantly over the past 
year.  Interest expense for 1996 decreased 7% from 1995 as short-term 
interest rates in 1996 were lower than rates during 1995.

Income Tax

    Income tax expense increased to $8.5 million for fiscal 1997 as compared 
to $3.8 million for fiscal 1996 and $2.3 million for fiscal 1995 primarily 
due to the increase in earnings before taxes. In addition, the increase in 
1997 from 1996 is due to the depletion of net operating loss carryforwards at 
the end of 1996.

Financial Condition, Liquidity, and Capital Resources

    Cash and cash equivalents and short-term investment with an affiliate were 
$18.8 million at the end of 1997 as compared to $24.3 million at the end of 
1996, a decrease of $5.5 million or 23%. This decrease is attributable to 
cash used in investing and financing activities exceeding cash provided by 
operating activities.  The Company continues to fund all of its investing and 
financing activities from cash flows from operations.

    Accounts receivable increased $15.3 million or 41% compared to 1996 
primarily due to the overall increase in sales for 1997 as well as an 
increase in international sales which typically allow for longer payment 
terms than domestic sales.

    Net affiliate accounts receivable/payable decreased $6.8 million from 
1996 mainly due to timing of cash received from unconsolidated affiliates.

    Inventories increased $12.2 million or 40% over 1996 primarily due to the 
addition of manufacturing capacity, including the FAB in Itzehoe, Germany, to 
support 1998 expected revenue growth.  In addition, inventory increased as 
the Company satisfied contractual requirements with key customers to maintain 
certain levels of safety stock.

    Other current assets increased $3.5 million or 44% over 1996 due to 
purchases of equipment and supplies on behalf of the Company's  
subcontractors in Taiwan and Germany, which are reimbursed at cost.

    Capital expenditures were $40.2 million in 1997 as compared to $39.5 
million in 1996.  These related mostly to additions for plant capacity 
expansion, new technology, and regulatory compliance.  Capital spending in 
1998, funded from cash provided by operating activities, is expected to 
exceed the 1997 level.

    Other assets increased $3.4 million over 1996 mainly due to the 
recognition of earnings under the equity method of accounting for the 
investment in Simconix, the Company's joint venture in The People's Republic 
of China (see Note 3 of Notes to Consolidated Financial Statements).

    Current liabilities increased $8.1 million or 10% over 1996 mainly due to 
the increase in accounts payable for capital equipment received before the 
close of the fiscal year.  In addition, the difference is attributed to the 
timing of cash remittances made to subcontractors in Taiwan and Germany.


<PAGE>

    Although the Company has available cash and cash equivalents and 
short-term investment with affiliate of $18.8 million at the end of 1997, 
cash and short-term investments with affiliate will decrease in the first 
quarter of 1998 to fund capital expenditures, royalty payments, commissions, 
and yearly management and employee bonuses.  Management expects 1998 cash 
flows from operations to be sufficient to fund investments in capital 
expenditures and research and development.

New Accounting Pronouncements

     In June 1997, the Financial Accounting Standards Board ("FASB") issued 
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting 
Comprehensive Income."  This statement establishes standards for reporting 
and presentation of comprehensive income and its components in the financial 
statements. It requires that a company classify items or other comprehensive 
income, as defined by accounting standards, by their nature in a financial 
statement. This statement  is effective for fiscal years beginning after 
December 15, 1997.  The effect of SFAS No. 130 will not be material to the 
Company's financial statement disclosure.

   In June 1997, FASB issued SFAS No. 131, "Disclosures about Segments of an 
Enterprise and Related Information." This statement, effective for fiscal 
years beginning after December 15, 1997, establishes standards for an 
enterprise to report information about operating segments in annual financial 
statements and interim financial reports. The segment information required to 
be disclosed under SFAS No. 131 is expected to be more comprehensive than 
previously provided, including expanded disclosure of income statement and 
balance sheet items for each of its reportable operating segments.  However, 
the Company has not yet determined the impact of this statement on the 
Company's financial statement disclosure.

Certain Factors

    The Company has in the past and may in the future make forward looking 
statements.  These statements are subject to risks and uncertainties that 
could cause actual results to differ materially from those predicted.  Such 
risks and uncertainties include, but are not limited to, the following:

Technological Change and Competition

    The markets for the Company's products are characterized by rapidly 
changing technology, frequent new product introductions, and declining 
average selling prices over product life cycles.  The Company's future 
success is highly dependent upon the timely completion and introduction of 
new products at competitive prices and performance levels, and upon having 
them selected for design into products of leading manufacturers.  In 
addition, the Company must respond to competitors in the Company's markets.  
If the Company is not able to make timely introduction of new products or to 
respond effectively to competition, its business and operating results could 
be adversely affected.

Variable Demand

    The semiconductor industry has historically been highly cyclical and has 
been subject to significant downturns at various times that have been 
characterized by diminished product demand.  Reduced demand for the Company's 
products could have an adverse effect on the Company's business and operating 
results.  The Company experienced a slowdown in bookings in the fourth 
quarter of 1997 attributable to market uncertainties.  This slowdown will 
negatively impact revenues in the first quarter of 1998 in comparison to the 
fourth quarter of 1997 and perhaps thereafter. In addition, it appears that 
earnings per share in the first quarter of 1998 will decline sharply in 
comparison to the fourth quarter and first quarter of 1997.

<PAGE>

Political and Economic Considerations

    In recent years, a large and increasing portion of the Company's net 
sales, operating profits, manufacturing production, and growth have come from 
its international operations.  As a result, the Company's business activities 
and its results could be significantly affected by the policies of foreign 
governments and prevailing political, social, and economic conditions.  In 
Asia Pacific, 1997 revenues were not materially impacted by the widespread 
weakness in Asian currencies and it is not certain what the long-term effect 
of the weakness of Asian currencies and the liquidity situation will be on 
our business.

Availability of Raw Materials

    The semiconductor industry has been increasing its manufacturing capacity 
over the past several years and is expected to continue to do so in the 
future. The Company anticipates that this environment may make it difficult 
for semiconductor companies  generally to ensure the required supply of 
silicon wafers from time to time.  The Company's results of operations could 
be adversely affected if its wafer suppliers are unwilling or unable to 
supply a timely and sufficient supply of product to the Company.

Intellectual Property Matters

    The semiconductor industry is characterized by litigation regarding 
patent and other intellectual property rights.  The Company has on occasion 
been notified that it may be infringing patent and other intellectual 
property rights of others.  In addition, customers purchasing components from 
the Company have rights to indemnification under certain circumstances if 
such components violate the intellectual property rights of others.  Although 
licenses are generally offered in such situations, and the Company has 
successfully resolved these situations in the past, there can be no assurance 
that the Company will not be subject to future litigation alleging 
intellectual property rights infringement, or that the Company will be able 
to obtain licenses on acceptable terms. An unfavorable outcome regarding one 
of these matters could have an adverse effect on the Company's business and 
operating results.

Year 2000 Compliance

    Many currently installed computer systems and software products are coded 
to accept only two digit entries in the date code field.  These date code 
fields will need to accept four digit entries to distinguish 21st century 
dates from 20th century dates.  As a result, many companies' software and 
computer systems may need to be upgraded or replaced in order to comply with 
such "Year 2000" requirements.  Although the Company believes that its 
products and systems are Year 2000 compliant, the Company utilizes 
third-party equipment and software that may not be Year 2000 compliant.  
Failure of such third-party equipment or software to operate properly with 
regard to the Year 2000 and thereafter could require the Company to incur 
unanticipated expenses to remedy any problems, which could have a material 
adverse effect on the Company's business and operating results.  Furthermore, 
the purchasing patterns of customers or potential customers may be affected 
by Year 2000 issues as companies expend significant resources to correct 
their current systems for Year 2000 compliance.  These expenditures may 
result in reduced funds available to purchase products and services such as 
those offered by the Company, which could have a material adverse effect on 
the Company's business and operating results.

NOTES TO
CONSOLIDATED FINANCIAL
STATEMENTS
 
 
Note 1 Organization and Significant Accounting Policies

Organization

   The Company was founded in 1962 and subsequently reincorporated on March 
5, 1987 in Delaware.  AEG Capital Corporation is the record holder of 80.4% 
of the Company's outstanding common stock as of December 31, 1997 (see Note 
12 of Notes to Consolidated Financial Statements).

Consolidation

   The accompanying consolidated financial statements include the accounts of 
the Company and its wholly owned subsidiaries.  All significant intercompany 
balances and transactions have been eliminated in consolidation.

Revenue Recognition

   The Company records sales to original equipment manufacturers and 
distributors at the time of shipment.  The Company records allowances against 
revenue for its standard distributor agreements which permit stock rotation 
and which provide price protection for distributors' inventory on hand when 
the Company reduces its published list prices.

Cash and Cash Equivalents  

   Cash equivalents consist of short-term financial instruments which are 
readily convertible to cash and have maturities of three months or less at 
the time of acquisition. 

Short-Term Investments

   Short-term investments consist of cash invested with Daimler-Benz Capital 
Incorporated ("DBCI"), an affiliated company as of December 31, 1997, within 
its cash concentration system, whereby cash is pooled and invested on a 
short-term basis (see Note 12 of Notes to Consolidated Financial Statements).

Inventories

   Inventories are stated at the lower of cost (first in, first out) or market.

Property, Plant, and Equipment

   Property, plant, and equipment are stated at cost.  Depreciation is 
computed for financial reporting purposes using primarily the straight-line 
method over the estimated useful lives of the respective assets.  The 
estimated lives used are 10 to 30 years for buildings and improvements and 3 
to 10 years for machinery and equipment.

Other Assets

   The investment in Simconix (a 50% joint venture with the Shanghai 
Institute of Metallurgy) is reported and presented under the equity method of 
accounting.

Long-Lived Assets

   During 1996, the Company adopted SFAS No. 121 "Accounting for the 
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed of." 
The provisions of SFAS No. 121 did not have a material effect on the 
Company's consolidated financial condition or results of operations.

Research and Development

   Expenditures for research and development are charged to expense in the 
year incurred.

<PAGE>

Financial Instruments and Credit Risk

   Due to the short maturities and/or the variable interest rates of the 
Company's financial instruments, including cash and cash equivalents, 
short-term investments, accounts receivable, debt obligations, accounts 
payable, and accrued liabilities, the carrying amounts approximate the fair 
value of the instruments.

   The Company's financial instruments that are subject to concentrations of
credit risk consist primarily of trade receivables.  The credit risk related to
the Company's trade receivables is mitigated by the Company's ongoing credit
evaluations of its customers' financial condition, reasonably short collection
terms, and the geographical dispersion of sales transactions.  The Company
generally does not require any collateral from its domestic customers although
letters of credit are used frequently throughout Asia.  Bad debt expense has
not been significant over the past three years.

   A material portion of the Company's revenues in 1997, 1996, and 1995 were 
derived from the worldwide communication and computer markets.  These markets 
have been historically somewhat volatile, as demand for the end-products in 
these markets has varied widely from time to time.  If demand for these 
end-products should decrease significantly, the producers thereof could 
reduce their purchase of the Company's products which in turn could have a 
materially adverse effect on the Company's consolidated financial position 
and results of operations.

Income Taxes

   Income taxes are accounted for under the asset and liability method.  
Deferred tax assets and liabilities are recognized for the future tax 
consequences attributable to differences between the financial statement 
carrying amounts of existing assets and liabilities and their respective tax 
bases as well as operating loss and tax credit carryforwards.  Deferred tax 
assets and liabilities are measured using enacted tax rates expected to apply 
to taxable income in the years in which those temporary differences are 
expected to be recovered or settled.  The effect on deferred tax assets and 
liabilities of a change in tax rates is recognized in income in the period 
that includes the enactment date.

   The Company has not provided for U.S. federal income taxes on $50.3 
million of non-U.S. subsidiaries' undistributed earnings as of December 31, 
1997, because such earnings are intended to be reinvested outside the United 
States indefinitely.  The deferred tax on this undistributed amount has not 
been determined as it is not practicable.

   At December 31, 1997, the Company is included in the consolidated federal 
and certain state tax returns of an affiliated company.  In accordance with 
the income tax allocation policy of the affiliated company, federal and state 
taxes are determined as if the Company was associated only with its wholly 
owned subsidiaries, taking into account all tax credits and all carryback and 
carryforward items.  For purposes of these consolidated financial statements, 
federal, state, and foreign income taxes have been allocated as if the 
Company's tax provision and related liability had been calculated on a 
separate return basis (see Note 12 of Notes to Consolidated Financial 
Statements).

Net Income per Share

   In 1997, the Company adopted SFAS No. 128, "Earnings Per Share."  SFAS No. 
128 requires the presentation of basic earnings per share ("EPS") and, for 
companies with complex capital structures, diluted EPS.  The Company has 
presented the accompanying consolidated financial statements under the 
provisions of SFAS No. 128.  The effect  of SFAS No. 128 was not material to 
the Company's financial statements.

Foreign Currency Translation

   The financial statements for certain of the Company's foreign subsidiaries 
are measured using the local currency as the functional currency.  Foreign 
assets and liabilities in the consolidated balance sheet have been translated 
at the rate of exchange as of the balance sheet date.  Revenues and expenses 
are translated at the average exchange rate for the year.  Translation 
adjustments do not impact the results of operations and are reported as a 
separate component of shareholders' equity. Foreign currency transaction 
gains and losses are included in the results of operations.

Use of Estimates

   Management of the Company has made a number of estimates and assumptions 
relating to the reporting of assets and liabilities and the disclosure of 
contingent assets and liabilities to prepare these consolidated financial 
statements in conformity with generally accepted accounting principles. 
Actual results could differ from these estimates.

New Accounting Pronouncements

   In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive 
Income."  This statement establishes standards for reporting and presentation 
of comprehensive income and its components in the financial statements. It 
requires that a company classify items or other comprehensive income, as 
defined by accounting standards, by their nature in a financial statement. 
This statement is effective for fiscal years beginning after December 15, 
1997.  The effect of SFAS No. 130 will not be material to the Company's 
financial statement disclosure.

<PAGE>

   In June 1997, FASB issued SFAS No. 131, "Disclosures about Segments of an 
Enterprise and Related Information." This statement, effective for fiscal 
years beginning after December 15, 1997, establishes standards for an 
enterprise to report information about operating segments in annual financial 
statements and interim financial reports. The segment information required to 
be disclosed under SFAS No. 131 is expected to be more comprehensive than 
previously provided, including expanded disclosure of income statement and 
balance sheet items for each of its reportable operating segments.  However, 
the Company has not yet determined the impact of this statement on the 
Company's financial statement disclosure.

Commitments and Contingencies

   Liabilities for loss contingencies, including environmental remediation 
costs, arising from claims, assessments, litigation, fines and penalties, and 
other sources are recorded when it is probable that a liability has been 
incurred and the amount of the assessment and/or remediation can be 
reasonably estimated. The costs for a specific clean-up site are discounted 
if the aggregate amount of the obligation and the amount and timing of the 
cash payments for that site are fixed or reliably determinable generally 
based upon information derived from the remediation plan for that site. 
Recoveries from third parties which are probable of realization are 
separately recorded, and are not offset against the related environmental 
liability.

Reclassification

   Certain reclassifications were made to the 1995 and 1996 balances to 
conform with the 1997 presentation.

Note 2 Related Party Transactions
 
   At December 31, 1997, the Company is a member of the semiconductor 
division of the Daimler-Benz Microelectronics Group, a consortium of 
affiliated companies referred to as TEMIC Semiconductors.  In addition to the 
Company, the other members of TEMIC Semiconductors are Telefunken 
Semiconductors, Matra MHS, and Dialog Semiconductor.  The aim of TEMIC 
Semiconductors is to unify the activities of the member companies to provide 
efficiencies by eliminating the duplication of many functions and to bring 
greater value to end customers by allowing them to deal with one entity for 
their semiconductor purchasing needs. In order to achieve these goals, four 
sales companies were established in 1995, TEMIC North America, TEMIC Asia 
Pacific, TEMIC France, and TEMIC Germany. These companies were established to 
fulfill all sales responsibilities for TEMIC Semiconductors within their 
respective regions.  TEMIC North America is a wholly owned subsidiary of 
Siliconix incorporated; TEMIC Asia Pacific is a division of TEMIC (S) Pte. 
Ltd., a wholly owned subsidiary of Siliconix incorporated; TEMIC France is a 
wholly owned subsidiary of Matra MHS; and TEMIC Germany is a division of 
Telefunken Semiconductors.  The sales companies function as agents of the 
manufacturing companies, namely Siliconix incorporated, Matra MHS, and 
Telefunken Semiconductors, through commission arrangements at a fixed 
percentage of sales.  Under these agreements, the sales companies perform all 
sales related functions under their legal names; however, the sales companies 
function only in an agency role and the ownership of all sales, receivables, 
inventory, and risk of loss remains with the manufacturing companies.

   TEMIC Semiconductors business unit is organized into two operating product 
divisions, Discrete Components and Integrated Circuits.  The operating 
structure is based on product groups and market segments and this allows 
TEMIC to manage the market's requirements more effectively.  The Discrete 
Components division headquarters are located in Santa Clara, California, USA 
and the Integrated Circuits division is located in Heilbronn, Germany.  The 
legally and financially autonomous subsidiaries of the TEMIC Semiconductors 
business unit remain intact.

   Several significant transactions and agreements entered into between the 
Company and these affiliates are disclosed elsewhere in these consolidated 
financial statements and related notes.  In addition, the following are other 
transactions between the Company and its affiliates during 1997, 1996, and 
1995.

   Under the TEMIC sales structure, commissions received pertaining to the 
sale of affiliate products in the North America and Asia Pacific regions were 
$15,017,000, $16,040,000 and $15,191,000 in 1997, 1996, and 1995, 
respectively, while commissions paid pertaining to the sale of the Company's 
products in Europe were $5,472,000, $4,361,000, and $4,232,000 in 1997, 1996, 
and 1995, respectively.  In 1997, the Company also paid $2,497,000 in 
commissions to affiliates of Daimler-Benz for the sale of the Company's 
products.  These commission amounts are included in selling, marketing, and 
administration expenses in the accompanying Statements of Operations.

   The Company participated in a cash concentration system established by 
Daimler-Benz North America ("DBNA"), an affiliated company, whereby cash is 
pooled and invested on a short-term basis with DBCI, an affiliate of DBNA, to 
obtain a higher rate of return. At December 31, 1997 and 1996, cash balances 
of $8,586,000 and $12,136,000, respectively, were invested with DBCI.  There 
are no restrictions related to the usage or withdrawal of these funds.  
Interest rates on the investment are based on the one-month LIBOR.  Interest 
income earned for 1997, 1996, and 1995 totaled $480,000, $421,000, and 
$410,000, respectively.  These interest income amounts are included in other 
income in the accompanying Statements of Operations.

   During 1997, the Company received $1,127,000 from a related party for 
research and development contracts.  Significant terms of these agreements 
included, but were not limited to, project coordination by the Company, 
project inspection by the related party, and assurance to the related party 
concerning the confidentiality of the technical information.  This amount is 
included in research and development expenses in the accompanying Statements 
of Operations.

   During 1997, 1996, and 1995, a related party was engaged to provide 
subcontract manufacturing services to the Company.  Fees for these services 
were $9,020,000, $4,467,000, and $4,591,000, respectively.  The amount paid 
in 1997 includes subcontract manufacturing fees for the Itzehoe fabrication 
facility which began production during the third quarter of 1997.  During 
1997, the Company also paid $9,226,000 to a related party for operating costs 
incurred by the Itzehoe facility during the pre-production period.  These 
subcontract fees and operating costs are included in cost of sales in the 
accompanying Statements of Operations. The Company is committed to pay for 
operating costs, regardless of the extent of actual manufacturing output, 
until December 31, 2007.  

   The Company entered into certain arrangements with related parties whereby 
the Company or the related party paid certain selling and administration 
expenses.  These expenses were then billed back on a periodic basis.  During 
1997, 1996, and 1995, the Company was reimbursed at cost, $11,113,000, 
$14,740,000, and $12,214,000, respectively, for selling and administrative 
expenses for related parties.  During the same periods, the Company 
reimbursed related parties at cost, $1,636,000, $2,256,000, and $2,223,000, 
respectively, for selling and administrative expenses.  These selling and 
administrative amounts are included in selling, marketing, and administration 
expenses in the accompanying Statements of Operations.  Management fee 
arrangements have been entered into by the Company and related parties to 
cover occupancy and administrative costs.  During 1997, 1996, and 1995, 
management fees received by the Company were $343,000, $712,000, and 
$555,000, respectively, and fees paid by the Company were $183,000, 
$1,853,000, and $139,000, respectively.  The management fee paid by the 
Company in 1996 included $1,670,000 related to legal, patent and licensing, 
and setup costs related to the Itzehoe plant in Germany.  These management 
fees are included in selling, marketing, and administration expenses in the 
accompanying Statements of Operations.

   During 1996, the Company incurred costs in connection with the set-up of 
the new Discrete Components division pertaining to the product lines of a 
related party.  Costs for 1996 which were billed back to a related party 
totaled $1,768,000.  This amount is included in selling, marketing, and 
administration expenses in the accompanying Statements of Operations.

   The Discrete Components and Integrated Circuits Divisions incur certain 
selling, marketing, and administration costs on behalf of the entire TEMIC

As of December 31, 1997, management believes that it is more likely than not 
that the deferred tax assets will be realized.  Thus, the valuation allowance 
was completely eliminated in 1997. The primary factor assessed by management 
in reaching its conclusion about the Company's net deferred income tax asset 
was the continued increases in earnings for the past seven years.

At December 31, 1997, the Company had the following carryforwards for tax
purposes:

Credits:

     California research and other business credits      $  5,700  No Expiration
     Alternative minimum tax credits                     $  1,450  No Expiration
</TABLE>

Utilization of the federal credit carryforwards incurred prior to 1991 is 
limited to $940,000 on an annual basis under the Tax Reform Act of 1986 as a 
result of the ownership change in 1990.

The Company has not provided for U.S. federal income taxes on $50.3 million 
of non-U.S. subsidiaries' undistributed earnings as of December 31, 1997, 
because such earnings are intended to be reinvested outside the United States 
indefinitely.

The Company's U.S. income tax returns for the years ended 1993, 1994 and 1995 
are presently under examination by the Internal Revenue Service. Management 
believes that any potential tax assessment plus related interest and penalty, 
if any, have been sufficiently provided for in the financial statements.

    Borrowings from a related party are at a floating interest rate based on 
DBCI's cost of securing commercial paper, 6.04% at December 31, 1997. 
Subsequent to year end, Vishay Intertechnology, Inc. ("Vishay") purchased the 
80.4% interest in the Company (see Note 12 of Notes to Consolidated Financial 
Statements).  As part of the acquisition, Vishay paid off the loan and 
established a new loan to the Company.  Although interest rates were not 
determined at the date of this transaction, Vishay intends to observe the 
same due date in 2001.  Therefore, the debt will continue to be classified as 
long-term.

    The Company issued $3,601,000 long-term trade deferral notes bearing 
interest at the 12-month London Interbank Offered Rate ("LIBOR") plus 0.5%. 
These notes were issued as partial compensation for trade claims.  Principal 
payments commenced in 1992, and the remaining trade deferral notes were paid 
off in 1997.

    The guaranteed floating rate subordinated notes bear interest at the 
three-month LIBOR plus 0.5% and are due in 2005.  The interest rate is fixed 
annually (6.21% at December 31, 1997).  The notes are guaranteed by an 
affiliated party, are subordinated to all other obligations of the Company, 
and are redeemable at the Company's option.

Debt (excluding unfunded retirement costs) at December 31, 1997, matures 
according to the following schedule: (In thousands)

Note 7 Geographic and Industry Segment Reporting
 
   The Company is engaged primarily in the designing, marketing, and 
manufacturing of power and analog semiconductor products. No other separate 
class of products or services constitutes more than 10% of net sales. Sales 
to the mass storage and computer market represented approximately 14% of net 
sales in 1997, 16% in 1996,  and 24% in 1995. Sales to the communication 
market increased to 23% of net sales in 1997, compared with 13% in 1996 and 
12% in 1995. A Japanese distributor accounted for 10% of net sales in fiscal 
1997. The same distributor accounted for 19% of net sales in fiscal 1996 and 
13% in fiscal 1995. Accounts receivable from this distributor totaled 
$3,999,000 and $8,187,000 at December 31, 1997 and 1996, respectively.

    The Company maintains manufacturing operations in the United States, 
Germany, Hong Kong (through subcontractors), and Taiwan as well as a joint 
venture in China and subsidiaries in the United Kingdom, Singapore, and Japan.

    Intercompany sales consist of products and services similar to those sold 
to external customers. Such sales are accounted for at amounts that are above 
cost and consistent with governing tax regulations. Identifiable assets are 
those assets used in each geographic area. Corporate assets are principally 
cash and cash equivalents and other miscellaneous corporate assets.

Information about the Company's operations by geographic area is shown in the

Note 9 Employee Benefit Plans
 
     The profit sharing element of the Siliconix incorporated Retirement Plan 
Trust (the "Plan") provides for annual contributions by the Company of up to 
10% of consolidated income before taxes (as defined). Vesting in the profit 
sharing element of the Plan occurs ratably over a five-year period. Upon 
employee termination, non-vested contributions are forfeited and reduce the 
Company's current and/or future contributions to the Plan.  The Company's 
contributions were $3,330,000, $2,525,000, and $2,242,000, in 1997, 1996, and 
1995, respectively. The tax deferred savings element of the Plan allows 
eligible employees to contribute up to 15% of their compensation. The Company 
matches a portion of each participating employee's contribution. The 
Company's matching contributions were $1,277,000, $1,266,000, and $1,112,000, 
in 1997, 1996, and 1995, respectively.

     The Company maintains defined benefit pension plans in the United States 
and Taiwan. The Company's U.S. defined benefit pension plan is for employees 
who met specified age and service eligibility requirements on January 1, 
1983. The Company's subsidiary in Taiwan has a defined benefit pension plan 
that covers substantially all of its employees.
 
The following table sets forth the funded status and amounts of the defined

Note 10 Employee Stock Plan
 
     From 1973 through the fourth quarter of 1990, the Company's Board of 
Directors authorized the sale of restricted common stock to certain key 
employees and directors for initial payments below market values. Vested 
shares are subject to the Company's lifetime right of first refusal to 
purchase the shares. In the event the Company declines to purchase the 
shares, a fixed amount of $3.06 (the "delta") determined by the Company's 
plan of reorganization is paid to the Company.  Fully vested shares 
outstanding under this plan at a delta of $3.06 per share at December 31, 
1997, 1996, and 1995, were 83,038, 96,945 and 102,389, respectively. There 
were no shares issued under this plan during 1997, 1996, and 1995. Vested 
shares sold by employees during 1997, 1996, and 1995 were 13,907, 5,444, and 
75,214, respectively, resulting in payments of $42,555, $16,659, and 
$230,155, respectively, to the Company which are included in additional 
paid-in-capital. During 1997, 1996, and 1995, no vested shares were sold to 
the Company.

Note 11 Contingencies
 
     The Company is party to two environmental proceedings. The first 
involves property that the Company vacated in 1972. The California Regional 
Water Quality Control Board ("RWQCB") issued a cleanup and abatement order to 
both the Company and the current owner of the property. The Company 
subsequently reached a settlement of this matter with the current owner in 
which the current owner indemnifies the Company against any liability that 
may arise out of any governmental agency actions brought for environmental 
cleanup of the site, including liability arising out of the current cleanup 
and abatement order. The second proceeding involves the Company's current 
facility in Santa Clara. The RWQCB issued a cleanup and abatement order based 
on the discovery of contamination of both the soil and the groundwater on the 
property by certain chemical solvents. The Company is currently engaged in 
certain remedial action and has accrued $750,000 as its best estimate of 
future costs related to this matter at December 31, 1997.

     In management's opinion, based on discussion with legal counsel and 
other considerations, the ultimate resolution of the above-mentioned matters 
will not have a material adverse effect on the Company's consolidated 
financial condition or results of operations.

     The Company is engaged in discussions with various other parties 
regarding patent licensing and cross-patent licensing issues. In the opinion 
of management, the outcome of these discussions will not have a material 
adverse effect on the Company's consolidated financial condition or overall 
trends in the results of operations.

was sold to a wholly-owned subsidiary of Vishay Intertechnology, Inc. of 
Malvern, Pennsylvania.  The Company's products will continue to be marketed 
with the Siliconix brand name under the Vishay umbrella.
