PART I.

ITEM 1.  BUSINESS

     General Description of Business

     Cable Design Technologies Corporation (the "Company", the "Registrant" or
"CDT") was incorporated on May 18, 1988 under the laws of the State of Delaware
with its principal office located at 661 Andersen Drive, Pittsburgh,
Pennsylvania 15220 (Telephone: 412-937-2300).

     CDT is a designer and manufacturer of specialty electronic data
transmission cables and network structured wiring systems. CDT products include
high performance copper, fiber optic, and composite cable constructions,
connectors and component assemblies that are used in network, communication,
computer interconnect, wireless, commercial aviation, automotive, automation &
process control, and other applications.

     The Company, as it exists today, was incorporated on May 18, 1988, but was
conceived in 1985 by its current President and Chief Executive Officer, Paul
Olson, together with other members of current management, shortly after its
predecessor company, Intercole, Inc., acquired the West Penn Wire Corporation
("West Penn/CDT"). In 1985 Intercole Inc., a Company traded on the American
Stock Exchange, was acquired by the Northern Group which subsequently took it
private. In 1988, the Company underwent a recapitalization pursuant to which
Golder, Thoma, Cressey Fund II purchased a controlling interest in the Company,
with the Northern Group retaining a smaller interest in the Company.

     Acquisitions have been an important part of CDT's growth strategy. In March
1986, the Company acquired Mohawk Wire & Cable Corporation ("Mohawk/CDT") , a
cable manufacturer which had established relationships with companies involved
in the early stages of computer network development. In December 1988, the
Company purchased Montrose Products Company ("Montrose/CDT"), a specialty
electronics cable company with established relationships with IBM and other
major purchasers of computer interconnect products. In August 1990, the Company
established CDT International to respond to increasing demand for data
transmission cable products in international markets. In May 1991, the Company
expanded its international presence by purchasing Anglo-American Cables Ltd.
("Anglo/CDT"), a European cable distributor. In March 1993, the Company
established Phalo/CDT to further increase its production capabilities and
broaden its product line. In May 1994, the Company acquired all the outstanding
stock of Nya NEK Kabel AB ("NEK/CDT"), located near Gothenburg, Sweden, to enter
the sophisticated broadcast, CATV and antenna cable markets and to expand
network systems cable manufacturing capacity into Europe. In June 1995, the
Company purchased all of the operating assets of Manhattan Electric Cable
Corporation ("Manhattan/CDT") based in Rye, New York to enhance sales of
specialty electronic cable for industrial automation and robotic applications.
In August 1995, the Company purchased Cole-Flex Corporation of West Babylon, New
York to combine its sleeving and tubing capabilities with Manhattan/CDT. In
September 1995, the Company purchased the operating assets of the Raydex
Division of Volex Group, p.l.c. ("Raydex/CDT") (United Kingdom) to provide
additional international manufacturing capabilities of specialty and high
performance electronic cable for computer network systems, telecommunication,
aerospace, CATV, and industrial applications. On February 2, 1996, the Company
acquired the assets of Northern Telecom Limited's ("Nortel") communication cable
and IBDN network structured wiring products businesses ("NORDX/CDT")

                                       2


(Canada). On June 4, 1996, the Company acquired the stock of Cekan A/S
("Cekan/CDT") (Denmark), a manufacturer of high performance, telecommunication
connectors. On July 25, 1996, the Company acquired, in exchange for shares of
its common stock, X-Mark Industries ("X-Mark/CDT") (Washington, PA), a
manufacturer of specialized metal enclosures for network systems. On March 14,
1997 the Company acquired 51% of the outstanding stock of Stronglink, Pty. Ltd.
("Stronglink/CDT") (Australia), to enhance international distribution of network
and specialty cable in the Australian marketplace. The Company subsequently
increased its ownership of Stronglink/CDT to 75%. On April 7, 1997, the Company
acquired the assets of Dearborn Wire & Cable, L.P. and its affiliates, Dearborn
West, L.P. and Thermax Wire, L.P. (collectively, "Dearborn/CDT"), a manufacturer
of specialty electronic cable for instrumentation and control, commercial
aviation, automotive and marine applications, and component assemblies for
wireless applications. In September 1997, the Company acquired all the
outstanding stock of Barcel Acquisition Corporation ("Barcel/CDT") of Irvine,
California, a manufacturer of high performance specialty cable for commercial
and military aviation applications. In March 1998, the Company acquired all the
outstanding stock of (Orebro/CDT) of Orebro, Sweden, a manufacturer of custom
designed wire and cable for wireless communication, robotics and other
industries. On August 3, 1998, the Company acquired 80% of HEW-Kabel Heinz
Eilentropp GmbH & Co. KG and related entities ("HEW-Kabel/CDT") located in
Wipperfurth, Germany, a manufacturer of specialty cable for process control,
robotics, transportation, medical and other specialty applications. On September
25, 1998, the Company purchased the assets of Network Essentials, Inc. ("Red
Hawk/CDT") of Milpitas, California. Red Hawk/CDT is a provider of fiber optic
products for voice, video and data networks. In March 1999, the company acquired
the Tennecast Company ("Tennecast/CDT") of Barberton, Ohio, a manufacturer of
precision aluminum tire castings and computer designed and machined mold models
utilized for tire castings.

     Products

     The Company's products are generally comprised of electronic copper and
fiber optic cable and network structured wiring components which are categorized
into two reportable segments, Network Communication and Specialty Electronic.
The markets served by the Company's products include computer local area
networks ("LANS") and wide area networks ("WANS"), communication, computer
interconnect, wireless, commercial aviation, automotive, automation & process
control, and other applications.

Network Communication Segment:
- ------------------------------

     The Company's Network Communication business segment encompasses
connectivity products for the electronic transmission of data, voice, and
multimedia over local and wide area networks and local loop communication
infrastructures. The products included in this segment are high performance
cable and passive components, including connectors, wiring racks and panels,
outlets and interconnecting hardware, for end-to-end network structured wiring
systems and communication cable products for outside communication and central
office switchboard and equipment applications. The Company entered the market
for communication cable products in fiscal 1996 with the acquisition of
NORDX/CDT. The Company's NORCOM/CDT facility in Kingston, Ontario, is the
largest communication cable operation in Canada. Additional capital expenditures
over the last three years have significantly increased the Company's production
capacity for network communication connectivity products.

                                       3


Network Communication segment sales were $373.0 million, $393.3 million and
$347.5 million for fiscal 1999, 1998 and 1997, respectively, and represented
approximately 55%, 60% and 67% of the Company's total sales for fiscal 1999,
1998 and 1997, respectively.


Specialty Electronic Segment:
- -----------------------------

     The Specialty Electronic business segment encompasses primarily electronic
data and signal transmission cables for automation and process control
applications and specialized wire and cable products for niche markets,
including computer interconnect, commercial aviation, automotive electronics,
broadcast and wireless communication.

     Automation & process control products encompass four distinct applications
for data and signal transmission cables. Automation applications include climate
control, premise video distribution and sophisticated security and signal
systems involving motion detection, electronic card and video surveillance
technologies. Process control applications include remote signaling and
electronic monitoring systems. Sound applications include voice activation,
evacuation and other similar systems. Safety applications refer to data
transmission cable for advanced fire alarm and safety systems, including cable
having improved safety and performance attributes under hazardous conditions.
Specialty products refers to a variety of highly engineered wire and cable
products covering a broad range of specialized applications and niche markets,
including commercial aviation and marine, automotive electronics, broadcast,
wireless component assemblies, communication switching equipment, CATV,
microwave antenna, medical electronics, electronic testing equipment, robotics
and electronically controlled factory equipment. Included in the Specialty
Electronic segment are non-cable manufacturing activities encompassing precision
tire casting and sheet metal fabrication which are not material to the Company's
business.

Specialty Electronic segment sales were $311.0 million, $258.4 million and
$169.5 million for fiscal 1999, 1998 and 1997, respectively, and represented
approximately 45%, 40% and 33% of the Company's total sales for fiscal 1999,
1998 and 1997, respectively.

     Raw Materials

     The principal raw materials used by CDT are copper and insulating
compounds. Raw materials are purchased on a consolidated basis whenever possible
to reduce costs and improve supplier service levels. Copper is purchased from
several suppliers. Price terms are generally producers' prices at time of
shipment. The Company does not generally engage in hedging transactions for the
purchase of copper. Currently, world stocks of and capacity for copper are
adequate to meet the Company's requirements. CDT purchases insulating compounds,
including Teflon(R), from various suppliers. Other raw materials used by CDT
include LEXAN(R), optical fiber, reels, tapes, textiles, chemicals and other
materials. Currently, supplies of these other raw materials are adequate to meet
the Company's needs and are expected to remain so for the foreseeable future.

     Customers

     The Company sells its products directly to original equipment manufacturers
(OEMs), regional Bell operating companies, certified system vendors, and
established distributors.  The Company supports over

                                       4


10,000 customers. No single customer accounted for more than 10% of sales in
fiscal 1999, 1998 or 1997, except that sales to business units of Bell Canada
Enterprises represented approximately 11% of fiscal 1997 sales.


Competition

The markets served by the Company's products are highly competitive.  Although
some of the Company's competitors are substantially larger and have greater
resources than the Company, management believes that it competes successfully in
its markets due to its experienced management team, manufacturing expertise,
breadth of product offerings and leading edge technology, large number of
customer approved specifications, emphasis on quality and established
reputation.

     The principal competitive factors in all the markets for Network
Communication and Specialty Electronic products are availability, customer
support, price and product features. The relative importance of each of these
factors varies depending on the specific product category.

     In the market for network structured wiring system products, the Company
competes with a large number of competitors, a few of which are significantly
larger than the Company. The Company competes in the network structured wiring
systems market by adapting to shifting customer demand for new products, and in
the case of NORDX/CDT, by offering complete, end-to-end certified network
structured wiring systems. In the markets for communication, switchboard and
equipment cable, price, reputation, production quality and availability are
principal competitive factors. In the automation & process control market, the
Company competes against a relatively large number of companies, most of which
are smaller in size than the Company. Product prices, company reputation and
product integrity are principal factors which affect competition in the
automation & process control market. In the specialty products market,
production quality, engineering capabilities and price are principal competitive
factors.


     Backlog

     Backlog orders believed to be firm were $90.4 million at July 31, 1999,
compared to $75.3 million at July 31, 1998. The Company believes that
substantially all of the backlog is shippable within the next twelve months.
Generally, customers may cancel orders for standard products without penalty
upon thirty days notice.


     Environmental Matters

     The Company is subject to numerous federal, state, provincial, local and
foreign laws and regulations relating to the storage, handling, emission and
discharge of materials into the environment, including the United States
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA),
the Clean Water Act, the Clean Air Act, the Emergency Planning and Community
Right-To-Know Act and the Resource Conservation and Recovery Act. Regulations of
particular significance to the Company include those pertaining to handling and
disposal of solid and hazardous waste, discharge of process wastewater and storm
water and release of hazardous chemicals. Although the Company believes it is in
substantial compliance with such laws and regulations, the Company may from time
to time not be in full compliance and may be subject to fines or other penalties
for noncompliance.

                                       5


     The Company does not currently anticipate any material adverse effect on
its business as a result of compliance with federal, state, provincial, local or
foreign environmental laws or regulations. However, some risk of environmental
liability and other costs is inherent in the nature of the Company's business,
and there can be no assurance that material environmental costs will not arise
in the future.

     Employees

     As of July 31, 1999, the Company had approximately 3,700 full-time
employees and 617 workers under contract manufacturing arrangements in Mexico.
Approximately 1,400 of the full-time employees are represented by labor unions.
The Company has not experienced any material work stoppages at its plants and
believes its current relations with its employees are good, however, there can
be no assurance that conflicts will not arise with unions or other employee
groups or that such conflicts would not have a material adverse effect on the
Company's business.


     Foreign Operations

     For information regarding the Company's foreign and domestic operations,
see Note 14, "Industry and Geographic Segment Information" as presented in the
Company's Notes to Consolidated Financial Statements.


     Research and Development

The Company engages in research and development activities including new and
existing product development. Research and development costs were $5.5 million,
$7.9 million and $7.2 million in fiscal 1999, 1998 and 1997, respectively. The
lower research and development expenses in fiscal 1999 were primarily the result
of the discontinuance in July 1998 of the DynaTraX (TM) product line and related
product development activities.


     Risk Factors

     Ability to Successfully Integrate Acquisitions. Growth through acquisitions
is an important part of the Company's strategy. Although the Company has been
successful in integrating previous acquisitions, no assurance can be given that
it will continue to be successful in integrating future acquisitions. The
integration and consolidation of acquired businesses will require substantial
management, financial and other resources and may pose risks with respect to
production, customer service and market share. While the Company believes that
it has sufficient financial and management resources to accomplish such
integration, there can be no assurance in this regard or that the Company will
not experience difficulties with customers, personnel or others. In addition,
although the Company believes that its acquisitions will enhance the competitive
position and business prospects of the Company, there can be no assurance that
such benefits will be realized or that any combination will be successful.

     Technological Obsolescence. Many of the markets that the Company serves are
characterized by rapid technological change. The Company believes that its
future success will depend in part upon its ability to enhance existing products
and to develop and manufacture new products that meet or anticipate such
changes. The failure to successfully introduce new or enhanced products on a
timely and cost-

                                       6


competitive basis could have a material adverse effect on the Company's
business.

     Fiber optic technology represents a potential substitute for copper-based
cable products. A significant decrease in the cost of fiber optic systems or
increase in the cost of copper-based systems could make fiber optic systems
superior on a price performance basis to copper systems and may have a material
adverse effect on the Company's business. To date, fiber optic cables have not
significantly penetrated the markets served by the Company due to the high
relative cost required to interface electronic and light signals and the high
cost of fiber termination and connection. Although the Company currently
supplies fiber optic cable in niche specialty markets and has excess capacity as
well as the technological expertise to expand capacity, there can be no
assurance that the Company will have sufficient production capacity for fiber
optic cable products in order to adapt to a potential significant increase in
demand for fiber optic cable products.

     Wireless technology, as it relates to premise network and communication
systems, may represent a threat to both copper and fiber optic cable based
systems by reducing the need for premise wiring. The Company believes that the
limited signal security and the relatively slow transmission speeds of current
premise wireless systems restrict the use of such systems in many data
communication markets. However, there can be no assurance that future advances
in wireless technology will not have a material adverse effect on the Company's
business.

     Products have recently been introduced by other companies that
electronically expand cable bandwidth. By enhancing cable performance, these
products allow expanded data services without upgrading existing cable. These
devices are being sold primarily to telephone companies to enhance local loop
and central office cable performance, eliminating costly replacement of aerial
and/or direct burial telephone cable. The Company believes that the complexity
these systems add to the maintenance and repair of a communication network
limits their attractiveness to users and consequently limits their effect on the
Company's business. There can be no assurance, however, that potential advances
in electronic cable enhancement will not have a material adverse effect on the
Company's business.

     Price Fluctuations and Availability of Raw Materials. Copper is the
principal raw material purchased by the Company, and the Company's sales may be
affected by the market price of copper. The Company does not generally engage in
hedging transactions for copper.

     The Company also purchases compounds, such as Teflon (R), from various
suppliers. From time to time, the supply of such materials has been limited. The
inability of suppliers to supply such raw materials could have a material
adverse effect on the Company's business until a replacement supplier is found
or substitute materials are approved for use. Although the Company has generally
been able to pass on increases in the price of copper and other raw materials to
its customers, there can be no assurance that the company will be able to do so
in the future. Additionally, significant increases in the price of copper or
other raw materials could have a negative effect on demand for the Company's
products. Similarly, significant decreases in the price of copper, or excess
supplies of such other raw materials, over time could have a material adverse
effect on the Company's business.

     Foreign Currency Fluctuations. The Company's operations may be adversely
affected by significant fluctuations in the value of the U.S. dollar against
certain foreign currencies or by the enactment of exchange controls or foreign
governmental or regulatory restrictions on the transfer of funds. The most
significant foreign currencies for the Company, in order of dollar equivalent
net sales, during fiscal 1999 were the Canadian Dollar, German Deutschmark and
the British Pound.

                                       7


     Competition. The Company is subject to competition from a substantial
number of international and regional competitors, some of which have greater
financial, engineering, manufacturing and other resources than the Company. The
Company's competitors can be expected to continue to improve the design and
performance of their products and to introduce new products with competitive
price and performance characteristics. Although the Company believes that it has
certain technological and other advantages over its competitors, realizing and
maintaining such advantages will require continued investment by the Company in
engineering, research and development, marketing and customer service and
support. There can be no assurance that the Company will have sufficient
resources to continue to make such investments or that the Company will be
successful in maintaining such advantages. See "Business -- Competition."

     Environmental Matters. The Company does not currently anticipate any
material adverse effect on its business as a result of compliance with federal,
state, provincial, local or foreign environmental laws or regulations or cleanup
costs. However, some risk of environmental liability and other costs is inherent
in the nature of the Company's business, and there can be no assurance that
material environmental costs will not arise in the future. Moreover, it is
possible that future developments, such as increasingly strict requirements of
air emission control and other environmental laws and enforcement policies
thereunder, could lead to material costs for environmental compliance and
cleanup by the Company.

     Year 2000 Compliance. The Company has a program in place to address the
Year 2000 date processing issue and its effect on the Company's information
technology ("IT") systems, non-IT systems, such as equipment and machinery
controlled by microcontrollers with embedded technology, and key suppliers and
customers. As of October 20, 1999 operating units representing approximately 99%
of the Company's consolidated revenues have completed any Year 2000 remediation
believed necessary with respect to their IT and non-IT systems. The remaining
units are expected to complete their remediation activities by November 30,
1999. The Company is assessing third party Year 2000 compliance, however as many
of the Company's suppliers and customers are still engaged in executing their
Year 2000 programs, the Company cannot fully evaluate such compliance. If,
however, the Company, its key suppliers and customers or other entities upon
which the Company relies (such as utility providers) fail to make necessary
modifications, conversions and contingency plans on a timely basis, the year
2000 issue could have a material adverse effect on the Company's business,
operations, cash flow and financial condition.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                           ON SUPPLEMENTAL SCHEDULE



We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in Cable Design Technologies
Corporation and Subsidiaries' annual report to stockholders incorporated by
reference in this Form 10-K, and have issued our report thereon dated September
20, 1999.  Our audits were made for the purpose of forming an opinion on those
financial statements taken as a whole.  The schedule listed in the accompanying
index is the responsibility of the Company's management and is presented for
purposes of complying with the Securities and Exchange Commission's rules and is
not part of the basic financial statements. This schedule has been subjected to
the auditing procedures applied in the audits of the basic financial statements
and, in our opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.
