Business Environment:  Circuit Protection Market

         The  circuit  protection  market can be broadly  categorized  into five
major product areas:  electronic,  automotive,  industrial (power), high voltage
and  residential.  The  Company  sells  products  designed  for the  electronic,
automotive  and industrial  areas.  The Company  entered the circuit  protection
market  in 1927  with the  development  and  introduction  of the  first  small,
fast-acting fuse capable of protecting  sensitive test meters.  Since that time,
the Company has diversified its involvement in the circuit  protection market to
become a leader in the  production  of  electronic  and  automotive  fuses.  The
Company  also  entered the power fuse market in 1983 with a broad line of fuses,
including several proprietary  products.  The Company believes it is the circuit
protection  leader  because it designs and  produces  almost all the products it
sells in all three  markets  including the two markets where it holds the number
one market share position. See "Littelfuse Products."

         Electronic Products. Electronic circuit protection products are used to
protect  power  circuits  in a  multitude  of  electronic  systems.  Electronics
products  fall into four  major  categories:  (1)  fuses,  (2)  protectors,  (3)
resettables  and (4)  electrostatic  discharge  suppressors.  Electronics  fuses
generally are of two types - miniature  and  subminiature.  Miniature  fuses are
generally  tubular  in  shape  with  glass,   ceramic  and  composition  bodies.
Subminiature devices are used where space is at a premium.  Protectors are fuses
produced to a less  rigorous  specification.  Resettables  are polymer  positive
temperature coefficient (PTC) devices that limit the current when an overcurrent
condition  exists and let current pass again after the cause of the  overcurrent
is removed.  Electrostatic discharge (ESD) suppressors are polymer based devices
that shunt transient high voltage energy away from circuitry.  Applications  for
electronic products include telecommunications equipment, computers and computer
peripherals,  power  supplies,  test and medical  instrumentation,  and consumer
electronic  products.  There is also a special segment of the electronic circuit
protection  market  directed  toward  the  aerospace  industry.   These  special
high-reliability fuses are manufactured in small quantities under extremely high
quality control standards.

         Automotive Products. Fuses are extensively used in automobiles, trucks,
buses and off-road equipment to protect electrical circuits and wiring harnesses
supplying  electrical  power  to  operate  lights,  heating,  air  conditioning,
windshield wipers, radios, windows and controls. Currently, a typical automobile
contains 30 to 70 fuses,  depending upon the options  installed.  The market for
automotive  fuses is  expected  to grow in the coming  years as more  electronic
features are included in automobiles. Certain new vehicles, such as the Cadillac
Seville,  Ford 150 series truck, Jeep Grand Cherokee and the Jaguar,  contain as
many as 50 to 90 fuses and this higher fuse count is expected to spread to other
vehicles.

         Power  Products.   Power  fuses  include  both  current   limiting  and
non-current   limiting  devices  used  to  protect  electrical  systems  against
overcurrents.  Power fuses are rated and listed under one of many  Underwriters'
Laboratories fuse  classifications.  The three main end user market segments for
power  fuses  include  original  equipment  manufacturers  ("OEMs"),  industrial
maintenance  and repair  operations  ("MROs") and new  commercial and industrial
construction.  Major  applications  for  power  fuses  include  protection  from
over-load  and  short-circuit  currents in motor  branch  circuits,  heating and
cooling systems, control systems,  lighting circuits and electrical distribution
networks.

Littelfuse Products

         General.  The Company is a leading manufacturer and seller of fuses and
other  circuit  protection  devices for use in the  electronic,  automotive  and
general  industrial  markets.  The  Company's  products are  marketed  under the
general  trademarked names of Littelfuse(R) and, where  appropriate,  Slo-Blo(R)

         Electronic Products. The Company manufactures and sells a wide range of
electronic circuit  protection  products,  including  miniature and subminiature
fuses,  protectors and resettables.  Electronic miniature and subminiature fuses
are designed to provide circuit  protection in the limited space requirements of
electronic equipment.  The Company entered the protector market in late 1994 and
the  resettable  polymer  PTC  device  market in late  1996.  While the  Company
continues to develop its own resettable fuse products,  the Company also entered
into  agreements  with  Raychem  Corp.  in 1996 which  allow the Company to sell
resettable fuses using certain of Raychem's technology.  The Company entered the
ESD suppressor  market in late 1998. The Company is in the process of developing
ESD suppressor  products and also purchased the Pulse-Guard(R)  product line and
technology in 1998.

The Company's  electronic  circuit  protection  products are marketed  under the
following trademarked and brand names:

              PICO(R) II Fuse is a very fast-acting subminiature fuse with axial
              leads which can be automatically inserted into a circuit board. It
              is used in consumer electronics,  computers,  medical instruments,
              power supplies and telecommunication line cards. It was originally
              developed for the aerospace  industry where  extremely  small size
              and  high  reliability  were  prime   requisites.   This  fuse  is
              encapsulated  with an epoxy coating  which  protects the fuse from
              adverse environmental  conditions. It can stand up under the rough
              treatment  found in high speed  automated  circuit board  assembly
              processes used by many different manufacturers.


              2AG fuses are a miniature version of the standard 1/4" diameter by
              1-1/4"  long  glass  bodied  fuses  manufactured  for more than 40
              years. The fuse occupies about 1/3 of the space but still provides
              the  performance  of the larger  sized  product.  The  Company has
              developed a strong market in the telecommunications industry for a
              leaded  version of the 2AG fuse.  These fuses are used in business
              and  personal  telephone  systems,  answering  machines  and other
              equipment  connected to phone lines.  They are used to protect the
              system from  lightning  surges and  accidental  contact with power
              lines.  These  fuses  also  are  used  extensively  in  electronic
              ballasts for lighting.

              NANO2  (R) SMF  Fuse is a fourth  generation  surface  mount  fuse
              product  line.  The  compact  size (.240" x .100" x .100") of this
              rectangular shaped fuse is very attractive to design engineers. In
              addition,   the  flat  side  design  permits  efficient  pick  and
              placement by automated assembly equipment.  The NANO2 (R) SMF Fuse
              is used where space considerations are critical,  including laptop
              computers, camcorders and battery chargers.

              ALF(TM) II or "1206" SMF is a very fast acting  thin film  surface
              mount fuse measuring  only .12 inch x .06 inch.  The  subminiature
              size   assures   additional   space   savings  in  surface   mount
              applications.  It is completely  compatible with common  soldering
              systems  used in surface  mount  assembly  applications  and it is
              available on 8mm reels for use with automatic placement equipment.
              Applications  include  hard disk drives,  PC main boards,  digital
              cameras and CD-ROMs.

              "0603"  SMF is a very fast  acting  thin film  surface  mount fuse
              measuring  only .06 inch x .03 inch. The 0603 is the smallest fuse
              available  and has a very  low  profile  .018  inches.  The  small
              physical  size along with low values for  resistance  and  voltage
              drop are  significant  features  of this new fuse for  battery and
              other low  voltage  applications,  such as hard disk drives and PC
              main boards.  The 0603 has also gained  acceptance  for use in the
              protection of cellular telephones.

              SMTelecom(TM)  is the first  surface  mount fuse to comply with UL
              1459  and UL 1950  third  edition  power  cross  requirements  for
              telecommunications.  The new SMTelecom(TM) Fuse protects all phone
              line connected  equipment  against  current surges  resulting from
              power cross,  power induction and lightning  strikes.  It is rated
              for 250 volts with a 600 volt short circuit  rating.  Four current
              ratings  are  offered,  from  0.75  to 1.5  amperes.  Applications
              include  modems,  fax  machines,  desktop  telephones,   answering
              machines and line cards.

              Surface  Mount  PTC is  the  first  in  Littelfuse's  line  of PTC
              devices.  Its dimensions of 0.200" x 0.290" x 0.120" are ideal for
              circuit board applications where space is at a premium. It also is
              available  in 0.340" x 0.250" x 0.10" and  0.179" x 0.127" x 0.02"
              configurations.  This polymer surface mount PTC has the ability to
              reset itself once the fault or overcurrent  condition has cleared.
              This new product is used  primarily  for computer  and  peripheral
              applications such as motherboards,  disk drives, PC cards, modems,
              printers, etc.

              PulseGuard(R), an ESD suppressor, is a polymer based surface mount
              or  connector  style  device  that  utilizes  a  variable  voltage
              material  to shunt high  voltage  ESD energy  away from  circuitry
              without affecting data signals. The PulseGuard(R)  characteristics
              and  available  packages  provide  for  protection  of  integrated
              circuitry in applications such as PCs and PC peripherals.

         Automotive  Products.  The Company is a primary  supplier of automotive
fuses to United  States,  Japanese  and  European  automotive  OEMs,  automotive
component parts  manufacturers  and automotive parts  distributors.  The Company
also sells its fuses in the  replacement  parts market,  with its products being
sold through mass merchandisers,  discount stores and service stations,  as well
as under private label by national firms.  Management believes that it currently
is the leading worldwide supplier of automotive fuses for new vehicle production
and a leader for the aftermarket/replacement market.

         The Company  invented and owns all of the U.S.  patents  related to the
blade  type  fuse  which is the  standard  and most  commonly  used  fuse in the
automotive industry. The Company believes that, together with its licensees,  it
supplies  substantially  all of the blade type fuses used in the North  American
and  Japanese  markets  and a majority in the  European  market.  The  Company's
automotive fuse products are marketed under the following  trademarked and brand
names:

              AUTOFUSE(R)  or  ATO(R),  a standard  blade type fuse,  is used in
              automobiles  produced  worldwide and designed to provide  superior
              circuit  protection  in a small,  heat  resistant  package for low
              ampere applications.

              MINI(R) Fuse, smaller than its predecessor AUTOFUSE(R), is offered
              in a range from two amps to 30 amps and is designed to permit more
              fuses in the same amount of space than prior products.

              MAXI(TM) Fuse, a larger version of the  AUTOFUSE(R),  replaces the
              commonly  used low  technology  fusible  wire or fusible  links in
              automobile  electrical harnesses and is offered in a range from 20
              amps to 80 amps.

              MIDI(R)  Fuse is a bolt down version of the  MAXI(TM)  fuse.  This
              style is preferred by some European customers in the 50 to 100 amp
              range. Its primary use is for heating,  air conditioning and motor
              control circuits.

              J-CASE(R)  Fuse, is a cartridge  version of the Maxi(TM) fuse. Its
              primary use is for branch  circuit  protection  and  protection of
              circuits with inductive loads.

               MEGA(R)Fuse,  a higher  current  fuse with  ratings of 100 to 200
               amps, is used for protection of battery cables.

         Over half of the Company's North American  automotive (blade type) fuse
sales are made to wire harness  manufacturers  that  incorporate  the fuses into
their  products.  The  remaining  automotive  fuse  sales are made  directly  to
automotive manufacturers and through distributors who in turn sell most of their
products to  automotive  product  wholesalers,  such as warehouse  distributors,
discount stores and service stations.

         The Company believes it currently has adequate  production  capacity to
meet the  anticipated  increased  demand for  automotive  fuses  referred  to in
"Business  Environment:  Circuit  Protection  Market --  Automotive  Fuses." Any
required  expenditures for additional machinery and equipment are expected to be
funded by cash flow from operations.

         The Company has  licensed  its  patented  ATO(R),  Mini(R) and Maxi(TM)
automotive fuse designs to Bussmann,  a division of Cooper Industries.  Bussmann
is the Company's  largest  domestic  competitor.  Additionally,  the Company has
entered into a licensing  agreement with Pacific  Engineering  Company,  Ltd., a
Japanese  fuse  manufacturer,  which  produces  and  distributes  the  Company's
patented ATO(R) and Mini(R)  automotive  fuses to the Pacific Rim  manufacturing
operations of Japanese based automobile  manufacturers.  See  "Competition"  and
"Business -- Patents, Trademarks and Other Intellectual Property."

         Power  Products.  The Company entered the power fuse market in 1983 and
manufactures and sells a broad range of low-voltage  circuit protection products
to electrical distributors and their customers in the construction,  OEM and MRO
markets. Power fuses are used to protect circuits in various types of industrial
equipment and circuits in industrial  plants,  office  buildings and residential
units.  The  Company's  power fuse  products  are marketed  under the  following
classifications:

              Class L fuses are  commonly  used as the first line of  electrical
              protection in building service entrance equipment of high capacity
              electrical systems.  Other applications  include switchboard mains
              and feeders,  distribution equipment and branch circuit protection
              for large motors.

              Class R fuses are commonly used downstream from Class L fuses in a
              variety of branch circuit  applications.  Both time delay and fast
              acting  versions  cover a range  of  applications  including  main
              feeder,  motor,  transformer  and  solenoids.  The  Company's  RK5
              INDICATOR  fuse series has won  numerous  product  awards and wide
              recognition  by industrial  plant  personnel.  These fuses have an
              integrated blown fuse indicator that turns from clear to dark once
              a fuse has blown. This reduces  troubleshooting time significantly
              and helps improve safety.

              Class J fuses are less  than  half the size of Class R to  provide
              substantial space savings. Applications for Class J are similar to
              Class R.  Additional  applications  include back up protection for
              circuit  breakers  and  protection  for both  IEC and  NEMA  rated
              devices.  The Company has also  introduced an indicating J line of
              fuses with indication functionality like the RK5 INDICATOR fuse.

              Class CC fuses, Littelfuse's KLDR (for transformer protection) and
              CCMR (for motor  branch  circuit  protection)  provide  protection
              formerly  supplied by fuses 10 times  larger.  Littelfuse  was the
              first to the market with these  products  and is the only  company
              with a CCMR rated up to 60 amps.

              Semiconductor  fuses,  designed for  supplementary  protection  of
              semiconducting devices, are used in electronic equipment and power
              equipment,  such as variable speed drives,  power rectifiers,  UPS
              systems and DC power suppliers.

              Midget fuses, in seven  different  series,  provide  supplementary
              overcurrent  protection  in such diverse  applications  as control
              circuits, control power transformers,  solenoids,  street lighting
              and computers.

              Medium voltage fuses, designed for general and back-up protection,
              protect motors,  transformers  and motor  controllers.  The medium
              voltage  fuse line was  expanded in 1998 with the  purchase of the
              product  line and  assets of a medium  voltage  fuse  manufacturer
              allowing for very short delivery times of these products.

         Other Products. In addition to the above products, the Company supplies
switches,  circuit breakers and indicator lights to the automotive  industry and
to  appliance  and  general  electronics  manufacturers.  The  Company is also a
supplier  of fuse  holders  (including  OMNI-BLOK(R)),  fuse  blocks  (including
Powr-Blok(R) power  distribution  systems) and fuse clips primarily to customers
that purchase circuit protection devices from the Company.


Product Design and Development

         The Company  employs  scientific,  engineering  and other  personnel to
improve its existing  product  lines and to develop new products at its research
and engineering facility in Des Plaines,  Illinois.  The Engineering  Department
consists of approximately 60 engineers, chemists, metallurgists, fusologists and
technicians.  This  department  is  primarily  responsible  for the  design  and
development  of new  products and  consists of eight major  groups:  two product
design, two materials  engineering,  one advanced  technology  development,  one
manufacturing engineering automation and two engineering support groups.

         Proposals for the  development of new products are initiated  primarily
by sales and marketing  personnel with input from customers.  The entire product
development process typically ranges from 6 to 18 months with continuous efforts
to reduce the development cycle.  During the fiscal years ended January 2, 1999,
January 3, 1998, and December 28, 1996, the Company expended  approximately $8.4
million,  $7.9 million and $7.3  million,  respectively,  on product  design and
development.

Patents, Trademarks and Other Intellectual Property

         The Company  generally  relies on patent and trademark laws and license
and nondisclosure  agreements to protect its rights in its trade secrets and its
proprietary products.  In cases where it is deemed necessary by management,  key
employees  are  required  to sign an  agreement  that  they  will  maintain  the
confidentiality of the Company's proprietary information and trade secrets. This
information, which for business reasons, is not disclosed to the public.

         As of January 2, 1999,  the Company owned 111 patents in North America,
23 patents in the European  Economic  Community  and 29 patents in other foreign
countries.  The Company has also registered  trademark protection for certain of
its brand names and logos.  The 111 North American  patents are in the following
categories:  50 Electronic,  7 Resettable,  26  Automotive,  19 Power Fuse and 9
miscellaneous.

         The first  patent  covering the  AUTOFUSE(R)  or ATO(R) fuse expired on
September 30, 1992.  However,  the last  improvement  patent covering the ATO(R)
fuse expires on September 19, 2000. The ATO(R) fuse product is further protected
by trademark and trade dress protection which has a remaining indefinite life so
long as it continues to be correctly used by the Company and its licensees.

         New products are continually being developed to replace older products.
The  Company  regularly  applies  for patent  protection  on such new  products.
Although in the aggregate  the Company's  patents are important in the operation
of its businesses, the Company believes that the loss by expiration or otherwise
of any one patent or group of patents would not materially affect its business.

         The Company currently licenses its MINI(R) and MAXI(TM) automotive fuse
technology  to  Bussmann,  a division  of Cooper  Industries  and the  Company's
largest  domestic  competitor.  The license granted in 1987 is nonexclusive  and
grants  the  Company  the right to  receive  royalties  of 4% of the  licensee's
revenues  from the sale of the  licensed  products  with an  annual  minimum  of
$25,000.  Each license  expires  upon the  expiration  of the  licensed  product
patents.

         The Company currently licenses its ATO(R) automotive fuse technology to
Pacific  Engineering  Company,  Ltd., a Japanese  manufacturer that produces and
distributes the Company's patented automotive fuses to Pacific Rim operations of
Pacific Rim-based automotive manufacturers. The license is exclusive as to Japan
and  non-exclusive  as to other  specified  Pacific Rim territories and provides
that the Company will receive royalties of 1.5% of the licensee's  revenues from
the sales of the licensed  products with a $25,000 annual minimum.  This license
expires on August 10, 1999. In addition,  a second license  covering the MINI(R)
Fuse  technology  was granted with  similar  territory  arrangements  to Pacific
Engineering  which provides the Company with royalties of 2.5% of the licensee's
revenues  from the sale of the  licensed  products,  with an annual  minimum  of
$100,000. This second license expires on April 6, 2006.

         License royalties amounted to $286,000, $332,000 and $266,000 for 1998,
1997 and 1996, respectively.






Manufacturing

         Much of the Company's manufacturing equipment is custom designed by its
engineers,  and the Company  conducts the majority of its own  fabrication.  The
Company  stamps  most of the metal  components  used in its fuses,  holders  and
switches  from raw metal stock and makes its own contacts and springs.  However,
the Company does depend upon a single  source for a  substantial  portion of its
stamped metal end caps for one family of electronic  fuses. The Company believes
that alternative stamping sources are available at prices which would not have a
material  adverse  effect on the  Company.  The Company  also  performs  its own
plating (silver,  nickel, zinc, tin and oxides). In addition,  all thermoplastic
molded component requirements used for such products as the AUTOFUSE(R), MINI(R)
and  MAXI(TM)  product  lines are met through  the  Company's  in-house  molding
capabilities.

         After components are stamped,  molded, plated and readied for assembly,
final assembly is accomplished on fully  automatic and  semi-automatic  assembly
machines.  Quality assurance and operations personnel,  using techniques such as
Statistical  Process Control,  perform tests, checks and measurements during the
production  process  to  maintain  the  highest  levels of product  quality  and
customer satisfaction.

         The principal raw materials for the Company's  products  include copper
and copper alloys,  heat resistant  plastics,  zinc,  melamine,  glass,  silver,
solder,  sulphate  chipboard  and  linerboard.  The Company  depends upon a sole
source for several heat resistant  plastics.  The Company believes that suitable
alternative  heat resistant  plastics are available from other sources at prices
which would not have a material adverse effect on the Company.  All of the other
raw materials are purchased from a number of readily available outside sources.

         A computer-aided  design and manufacturing  system (CAD/CAM)  expedites
product  development  and  machine  design,  while  reliability  and high  power
laboratories test new products,  prototype  concepts and production run samples.
The Company  participates in  "Just-in-Time"  delivery programs with many of its
major  suppliers  and  actively  promotes  the  building  of strong  cooperative
relationships  with its suppliers by involving them in  pre-engineering  product
and process  development.  The Company also  sponsors an annual  major  supplier
conference and conducts a vendor certification program.

Marketing

         The Company's domestic sales staff of approximately 66 people maintains
relations with major OEMs and distributors.  The Company's sales and engineering
personnel  interact  directly with the OEM engineers to ensure  maximum  circuit
protection   and   reliability   within  the   parameters  of  the  OEM  design.
Internationally,  the Company maintains a sales staff of approximately 30 people
and sales offices in The Netherlands,  England,  Singapore, Korea and China. The
Company also markets its products indirectly through a worldwide organization of
approximately  125  manufacturers'  representatives  and distributes  through an
extensive network of electronic, automotive and electrical distributors.

         Electronic. The Company has retained 23 manufacturers'  representatives
to sell its electronic products  domestically and additional  representatives to
sell its electronic  products  internationally.  These  representatives  call on
major OEMs and distributors.  The Company  distributes  approximately 41% of its
domestic products directly to OEMs, with the remainder  distributed by more than
800 distributors nationwide.

         In the Asia-Pacific  region, the Company maintains a direct sales staff
of five people in Singapore,  one in Hong Kong,  seven in Korea, and one or more
manufacturers'  representatives in Japan,  Singapore,  Korea, Hong Kong, Taiwan,
China, Malaysia, Thailand, Philippines and Australia. The Company also maintains
an engineering facility in Japan. In Europe, the Company's  distribution methods
differ from its domestic methods in that it maintains a direct sales force of 17
people to call on OEMs exclusively and utilizes  approximately 15 manufacturers'
representatives  to approach  distributors and smaller OEMs. Unlike its domestic
representatives,  these manufacturers'  representatives  purchase inventory from
the Company to facilitate  delivery and reduce  financial risks  associated with
currency exchange rate fluctuations.

         Automotive.  The Company sells  automotive fuses through a direct sales
force in Detroit  consisting  of four  employees.  Salespersons  service all the
major automotive OEMs (including the United States  manufacturing  operations of
foreign-based  OEMs) through both the engineering and purchasing  departments of
these  companies.   Twenty-two  manufacturers'  representatives  distribute  the
Company's  products to aftermarket  fuse  retailers such as Autozone,  Pep Boys,
K-Mart and NAPA.  In Europe,  the  Company  uses both a direct  sales  force and
manufacturers' representatives to distribute its products to Mercedes Benz, BMW,
Volvo, Saab, Jaguar and other OEMs, as well as aftermarket distributors.  In the
Asia-Pacific  region, the Company has licensed its automotive fuse technology to
a Japanese  firm which  supplies  the  majority of the  automotive  fuses to the
Japanese  manufacturing  operations in the region  including  Toyota,  Honda and
Nissan.


         Power.  The  Company  markets  and  sells its power  fuses  through  36
manufacturers'  representatives across North America. These representatives sell
power fuse products  through an  electrical  distribution  network  comprised of
approximately 1,200 distributors. These distributors have customers that include
electrical contractors,  municipalities, utilities and factories (including both
MRO  and  OEM).  Some  of  the  manufacturers'  representatives  have  consigned
inventory in order to facilitate rapid customer delivery.

         The Company's field sales force (including  application  engineers) and
manufacturers'   representatives   call  on  both   distributors  and  end-users
(consulting  engineers,  municipalities,  utilities  and  OEMs) in an  effort to
educate these customers on the capabilities and characteristics of the Company's
products.

Business Segment Information

The Company has three reportable  business  segments:  The Americas,  Europe and
Asia-Pacific.  For information  with respect to the Company's  operations in its
three  geographic  areas for the fiscal year ended January 2, 1999, see "Item 8.
Financial  Statements and  Supplementary  Data - Business  Segment  Information"
incorporated herein by reference.







Customers

         The  Company  sells  to over  10,000  customers  worldwide.  No  single
customer  accounted  for more than 10% of net sales  during the last three years
except for its Japanese  stocking  representative  which  accounted for 10.2% in
1998. The Japanese stocking representative serves over 100 customers in the Asia
Pacific  electronic  market.  During the 1998,  1997 and 1996 fiscal years,  net
sales to customers  outside the United States  (exports and foreign  operations)
accounted  for  approximately  43.0%,  40.6%  and  38.5%,  respectively,  of the
Company's total net sales.

Competition

         The  Company's   products   compete  with  similar  products  of  other
manufacturers, many of which have substantially greater financial resources than
the Company.  In the  electronic  fuse market,  the  Company's  competitors  are
Bussmann, a division of Cooper Industries,  Bel Fuse, Inc., Raychem Corp., San-O
Industrial  Corp. and  Wickmann-Werke  GmbH. In the  fuseholder  portion of this
market, the Company's principal  competitor is Schurter,  Inc. In the automotive
fuse  market,  the  Company's  major  competitor,  both in sales  to  automobile
manufacturers and in the aftermarket,  is Bussmann. The Company licenses several
of its automotive fuse designs to Bussmann.  Other auto fuse competitors include
Pudenz and MTA.  In the power  fuse  market,  the  Company's  major  competitors
include Bussmann,  Gould, Inc and Ferraz.  The Company believes that it competes
primarily on the basis of innovative products,  the breadth of available product
lines,  the quality and design of its  products  and the  responsiveness  of its
customer service rather than through price competition.

Backlog

         The Company  does not consider  backlog to be a  predictive  measure of
results due to the Company's short delivery time. The Company  manufactures high
volume  products  based on its  demand  forecasts  and  manufactures  low volume
products based on customer orders. The Company attempts to ship such products to
the customer within five business days of the date of the order. Over 90% of all
orders,  which request delivery within three weeks of the date of the order, are
filled on time from available stock or current production.

Employees

         During  1998,  the  Company  employed   approximately   3,085  persons.
Approximately  50  employees  in Des  Plaines  and 450  employees  in Mexico are
covered by collective bargaining  agreements.  The Des Plaines agreement expires
March 31, 1999 and the Mexico  agreement  expires  January 31, 2001. The Company
has not  experienced any work stoppage or other form of labor dispute within the
last 20 years.  The Company  believes that its employee  relations are excellent
and that its  employees,  many of whom have long  experience  with the  Company,
represent a valuable  resource.  The Company  emphasizes  employee  training and
development and has established  Quality  Improvement Process (QIP) training for
its  employees   worldwide  so  as  to  promote  product  quality  and  customer
satisfaction.








Year 2000

For information  relating to year 2000 see "Item 7. Management's  Discussion and
Analysis  of  Financial  Conditions  and  Results  of  Operations  - Year  2000"
incorporated herein by reference.

Environmental Regulation

         The Company is subject to numerous federal, state and local regulations
relating to air and water quality,  the disposal of hazardous  waste  materials,
safety and health.  Compliance with applicable environmental regulations has not
significantly changed the Company's  competitive  position,  capital spending or
earnings  in the  past  and the  Company  does  not  presently  anticipate  that
compliance with such regulations will change its competitive  position,  capital
spending  or  earnings  for the  foreseeable  future.  The  Company  employs  an
environmental  engineer to monitor  regulatory  matters and believes  that it is
currently in compliance in all material  respects with applicable  environmental
laws and regulations.

     ITEM 5.  Market for  Registrant's  Common  Equity and  Related  Stockholder
Matters The  information set forth under  "Quarterly  Stock Price" on page 38 of
the Annual Report to  Stockholders is  incorporated  herein by reference.  It is

Annual Report to Stockholders is  incorporated  herein by reference.  It is also
included in Exhibit 13.1 as filed with the SEC.


ITEM 7A.  Quantitative and Qualitative Disclosures about Market Risks

The Company is exposed to market risk from  changes in interest  rates,  foreign
exchange rates and commodities.


The Company had  long-term  debt  outstanding  at January 2, 1999 in the form of
Senior  Notes and lines of credit at both  variable  and fixed  interest  rates.
Since  substantially  all of the debt has fixed  interest  rates,  the Company's
interest expense is not sensitive to changes in interest rate levels.

A portion  of the  Company's  operations  consists  of  manufacturing  and sales
activities in foreign  countries.  The Company has  manufacturing  facilities in
Mexico,  England,  Switzerland,  South Korea, China and the Philippines.  During
1998, sales exported from the United States or manufactured abroad accounted for
43.0% percent of total sales.  Substantially all sales in Europe are denominated
in Dutch Guilders,  British Pound Sterling and Euros and substantially all sales
in the  Asia-Pacific  region are  denominated in United States Dollars and South
Korean Won.

The Company's  identifiable  foreign exchange exposures result from the purchase
and sale of products from affiliates,  repayment of intercompany  trade and loan
amounts and translation of local currency  amounts in consolidation of financial
results.  Changes in foreign currency exchange rates or weak economic conditions
in the foreign countries in which it manufactures and distributes products could
affect the Company's sales and financial  results.  Other than utilizing netting
and  offsetting  intercompany  account  management  techniques  to reduce  known
exposures, the Company does not use derivative financial instruments to mitigate
its foreign currency risk at the present time.

The Company uses various  metals in the  production of its  products,  including
zinc, copper and silver.  The Company's  earnings are exposed to fluctuations in
the prices of these  commodities.  The Company does not currently use derivative
financial instruments to mitigate this commodity price risk.
