ITEM 1.  BUSINESS

General

         Littelfuse,   Inc.  (the  "Company"  or   "Littelfuse")  is  a  leading
manufacturer and seller of fuses and other circuit protection devices for use in
the electronic,  automotive and general industrial markets.  Management believes
the Company is ranked first in market share in the electronic  market,  first in
the  automotive  market  and third in the power  fuse  market in North  America.
Management believes that the Company, together with its licensees, is also first
in market  share in the  electronic  market and first in the  automotive  market
worldwide.

         In the electronic  market,  leading  manufacturers such as 3Com, Canon,
Compaq,  Hewlett Packard,  IBM, LG Electronics,  Lucent Technologies,  Motorola,
Nortel,  Panasonic,  Samsung,  Sharp,  Sony,  and Toshiba  obtain a  substantial
portion of their electronic circuit protection requirements from the Company. In
the automotive market, the Company or its licensees have customer  relationships
with all  leading  automobile  manufacturers  throughout  the world.  Littelfuse
provides  substantially  all of the automotive  fuse  requirements  for vehicles
manufactured  domestically  by General  Motors  Corporation  and is the  primary
supplier for Ford Motor Company,  Chrysler Corporation and all Japanese and most
European auto manufacturer  transplants.  The Company also competes in the power
fuse market selling to companies such as the Allen Bradley  division of Rockwell
International  and  Reliance  Electric.   In  addition  to  fuses,  the  Company
manufactures and supplies switches, circuit breakers and indicator lights to the
automotive industry and to appliance and general electronics manufacturers.  See
"Business Environment: Circuit Protection Market."

         The Company manufactures its products on fully integrated manufacturing
and  assembly  equipment,  much  of  which  is  designed  and  built  by its own
engineers.  The Company  fabricates and assembles a majority of its products and
maintains  product quality through a rigorous quality assurance program with all
sites (except the Philippines)  certified under ISO 9000 standards and its world
headquarters now certified under the QS9000 standards.

         The Company's  products are sold worldwide through a direct sales force
and manufacturers'  representatives.  In Asia Pacific,  the Company has licensed
its automotive fuse technology to a Japanese firm that supplies automotive fuses
to Pacific Rim customers.  For the year ended January 3, 1998, approximately 41%
of the Company's net sales were to customers  outside the United States (exports
and foreign operations).

         The Company was incorporated under the laws of the State of Delaware on
November 25, 1991.  The Company is the successor to the business and assets of a
corporation of the same name ("Old Littelfuse"),  which was originally formed in
1927  and  subsequently  acquired  by  Tracor,  Inc.  ("Tracor")  in  1968.  Any
references  to  performance,  financial  results or other aspects of the Company
prior to December 27, 1991, relate to Old Littelfuse.

     References  herein to "1995" or "fiscal  1995" refer to the  calendar  year
ended December 31, 1995.  References  herein to "1996" or "fiscal 1996" refer to
the fiscal year ended December 28, 1996.  References herein to "1997" or "fiscal
1997"  refer to the fiscal  year ended  January 3, 1998.  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 three major  categories:  (1) fuses,  (2)  protectors and (3)
resettables.  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 PTC devices that limit the current when an  overcurrent
condition  exists and let current pass again after the cause of the  overcurrent
is removed.  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  and as larger  amperage  fuses  replace
existing low technology fuses in wiring harnesses. Certain new vehicles, such as
the Cadillac Seville,  Ford 150 series truck,  Chrysler Concorde 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.  Other  applications  include the protection of semiconductor  devices
such as SCRs, diodes, thyristors, triacs and similar solid state devices.

         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 allows the Company to sell
resettable fuses using certain of Raychem's technology.

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.


                                                      -3-





              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.

              MICRO(TM)  Fuse is a plug-in style fuse about the size of a pencil
              eraser.  It is a very fast acting fuse and, like the PICO(R) Fuse,
              was  originally  designed  for the  emerging  aerospace  industry.
              Applications are  particularly  suited to equipment where the user
              might "blow" a fuse during  testing or by accidental  shorting out
              of the power supply.  The "plug-in"  feature allows the fuse to be
              quickly  and  easily   replaced   without  the  need  for  special
              de-soldering equipment.  The Company also manufactures sockets for
              the MICRO(TM) Fuse.

              NANO2 (R) SMF Fuse represents our 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 super  small
              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.

              "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.

              SMTelecom is the first  surface  mount fuse to comply with UL 1459
              and  UL  1950  third   edition   power  cross   requirements   for
              telecommunications. The new SMTelecom Fuse protects all phone line
              connected equipment against current surges resulting from power

                                                      -4-





              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 an  0.340"  x  0.250"  x 0.10"  configuration.  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.

              Radial Leaded PTC series is a 60-volt  radial leaded surface mount
              product.  This series was introduced in early 1997.  Radial leaded
              PTC applications include process and industrial controls, test and
              measurement equipment, security systems, motors and automotive.

         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.
                                                      -5-


              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 Fuse,  is a cartridge  version of the Maxi(TM)  fuse.  This
              style  is  popular  with  Japanese  customers  in the 40 to 80 amp
              range.  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 Pacific Rim-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,
                                                      -6-





              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.

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

         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.

         The  LITTELITES(R)  indicating  lights product line includes  cartridge
lamps with miniature and subminiature lampholders and snap-mount plastic lights.
These lights come in incandescent, neon and solid state versions.  LITTELITES(R)
are sold to producers of  industrial  machinery,  office  machines,  appliances,
instruments and computers.

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 of the
groups are  dedicated to the design of certain  types of products,  specifically
electronic fuses, including automotive and general electronic fuses;  electrical
fuses, including power and industrial fuses.

                                                        -7-






There are two engineering groups dedicated to materials engineering which brings
metallurgy,  plating and other  technologies  to bear on the  development of new
products.  One of the eight groups is responsible  for developing the technology
for advanced new  products.  There is one group  responsible  for  manufacturing
engineering  automation.  Finally, the two remaining  engineering support groups
oversee  trademark  compliance,  drafting  rooms  and an  electronics  lab.  The
electronics  lab  develops  the  necessary  tooling,  hardware  and software for
testing the standards and tolerances of sample  products and maintains the model
shop.

         Proposals for the  development of new products are initiated  primarily
by  marketing  managers,  members of the sales staff and  customers.  The entire
product development process typically takes between 12 and 18 months. During the
fiscal years ended  January 3, 1998,  December 28, 1996,  and December 31, 1995,
the Company expended  approximately $7.9 million, $7.3 million and $7.9 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
is information, which for business reasons, is not disclosed to the public.

         As of January 3, 1998,  the Company owned 101 patents in North America,
19 patents in the European  Economic  Community  and 27 patents in other foreign
countries.  The Company has also registered  trademark protection for certain of
its brand names and logos.  The 101 North American  patents are in the following
categories:  48 Electronic,  5 Resettable,  25  Automotive,  15 Power Fuse and 8
miscellaneous.  Of the 25 automotive  patents, 7 are article and process patents
for the ATO(R)  type fuses,  9 are for the MINI(R) and MAXITM type fuses,  3 are
for the MEGA(R) and MIDI(R) type fuses and 6 are for other automotive  products.
Patents  expiring in 1998 cover  products  that  accounted for 1% of 1997 sales.
Patents  covering  products that  accounted for the balance of 1997 sales expire
between 1999 and 2016.

         The first  article  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 August 10,  1999.  The ATO(R)  fuse  product is further
protected  by  trademark  and  trade  dress  protection  which  has a  remaining
indefinite  life so long as it is continued 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.



                                                        -8-





         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 and grants the Company the right to receive royalties of 2.5% of the
licensee's  revenues  from the sale of the  licensed  products,  with an  annual
minimum of $100,000. The second license expires on April 6, 2006.

         License royalties amounted to $332,000, $266,000 and $349,000 for 1997,
1996 and 1995 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  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  clipboard  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.

                                                        -9-


         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 65 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 25 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.

         In addition to the normal risks associated with the Company's  domestic
operations,  the Company's international operations entail such further risks as
currency fluctuations and the effect of international  relations or the domestic
affairs of foreign countries on the conduct of business.  As of January 3, 1998,
the Company's  operations have been slightly effected by the currency turmoil in
Asia Pacific during the fourth quarter of 1997. For information  relating to the
constant  currency  effect see "Item 7.  Management  Discussion  and Analysis of
Financial  Conditions  and Results of  Operations - 1997  Compared to 1996." For
information relating to foreign sales, see note 8 to the Company's  consolidated
financial statements.

         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.  Since the  manufacturers'  representatives  do not
maintain inventories,  the Company distributes approximately 38% of its domestic
products  directly  to OEMs,  with the  remainder  distributed  by more than 600
distributors nationwide.

         In Asia  Pacific,  the Company  maintains a direct  sales staff of five
people  in  Singapore,  one in  Hong  Kong,  four  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
eight  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.


                                                       -10-





         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-eight  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 Asia
Pacific,  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  42
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.


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 11% in 1997.
The  Japanese  stocking  representative  serves over 100  customers  in the Asia
Pacific  electronics  market.  During the 1997, 1996 and 1995 fiscal years,  net
sales to customers  outside the United States  (exports and foreign  operations)
accounted  for  approximately  40.6%,  38.5%  and  35.3%,  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,

                                                       -11-





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  1997,  the  Company  employed   approximately   2,845  persons.
Approximately  50  employees  in Des  Plaines  and 465  employees  in Mexico are
covered by collective bargaining  agreements.  The Des Plaines agreement expires
March 31, 1999 and the Mexico  agreement  expires  January 31, 1999. 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.

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.
