                                        PART I

ITEM 1.   BUSINESS

     ADC designs, manufactures, markets and integrates a broad range of 
products and services that enable its customers to construct and upgrade 
their telecommunications networks to support increasing user demand for 
voice, data and video services, primarily within an area of the 
telecommunications market known as the "local loop." The local loop is the 
portion of the public network from the central office, through the equipment 
that connects the local central office to the subscriber's equipment, onto 
the customer's premises and across the enterprise or residential network.  
Telephone companies, cable television operators, wireless network providers 
and other public network providers are building the infrastructure required 
to offer Internet access, higher speed data, video and telephony services, 
entertainment and other interactive services to residential and business 
customers.  Greater and greater amounts of network bandwidth are required for 
these services, and the Company's development efforts and product offerings 
are focused on "unlocking the capacity of the local loop," eliminating 
bottlenecks and increasing the speed and efficiency of the network.

     The Company's products include equipment, services and integrated solutions
within three functional product groups: transmission, enterprise networking and
broadband connectivity.  The Company's transmission products are designed for
use in copper-based, coax-based, fiber-based or wireless transmission networks
and are sold primarily to public network providers in the United States and
internationally.  The Company's enterprise networking products are designed for
use in copper-based, fiber optic and wireless networks and are sold primarily to
private voice, data and video network providers around the world.  The Company's
broadband connectivity products are designed for use in copper-based, coax,
fiber optic or wireless transmission networks and are sold to both public and
private global network providers.

     The Company's customers include:  public network providers, which consist
of all five of the Regional Bell Operating Companies (RBOCs), post telephone and
telegraph companies (PTT's), other telephone companies, long distance carriers,
wireless service providers, major cable TV operators, Internet service providers
and other international and domestic public network providers; private and
governmental network providers (such as various large business customers and
governmental agencies); and major telecommunications Original Equipment
Manufacturers (OEMs).

     As used in this report, unless the context otherwise requires, the terms
"Company" and "ADC" refer to ADC Telecommunications, Inc. and its wholly owned
and majority owned subsidiaries; 1995, 1996 and 1997 refer to the Company's
fiscal years ended October 31, 1995, 1996 and 1997, respectively; and 1998
refers to the Company's fiscal year ending October 31, 1998.

INDUSTRY BACKGROUND

     Since the Company entered the telecommunications equipment industry in the
1970s, the industry has grown and changed substantially, primarily as a result
of continuous technological development; increased demand for new, higher speed,
higher capacity services such as Internet access, digital video and advanced
wireless services; the convergence of all voice, data and video network traffic
into integrated multimedia services over public and private networks; and a
changing regulatory and competitive environment.  The Company believes that
these trends will continue to drive changes in the telecommunications equipment
industry for the foreseeable future.

     Several important technological developments have spurred the evolution of
the telecommunications equipment industry.  One important technological change
has been the deployment


                                          2
<PAGE>

of fiber optic transmission systems.  In a fiber optic system, lasers transmit
voice, data and video traffic in the form of analog or digital coded light
pulses through glass fibers.  The increasing shift to fiber optic transmission
systems has been principally due to the ability of fiber optics to carry large
volumes of information at high speeds, its insensitivity to electromagnetic
interference and the high transmission quality made possible by the physical
properties of light.  As technologies such as Synchronous Optical NETwork
(SONET), Dense Wave Division Multiplexing (DWDM) and 1550 nanometer laser
transmission technologies have evolved over the last several years, the capacity
of fiber optic systems to transport information has increased significantly.

     The development of cost-effective digital technology has also allowed
greater capacity (or speed) in network transmission and has resulted in an
increasing trend over the past decade to replace analog technology in copper,
fiber and wireless transmission networks.  In analog technology, information is
converted to a voltage or current wave form for processing or transmission.  In
digital technology, information is converted to digital bits and then processed
or transmitted using computer based components.  Very high-speed digital
technology developments such as SONET, cell based Asynchronous Transfer Mode
(ATM) and Orthogonal Frequency Division Multiplexing (OFDM) modulation
technologies have enabled network providers to transmit increasing amounts of
data and video communications.

     Another important technological change in the telecommunications
marketplace is the use of integrated circuits in both public and private
telecommunications networks, facilitating significantly more complex networks.
Network equipment utilizing integrated circuits is increasingly performing the
high speed switching, network performance monitoring, network management,
information compression, data translation and other complex functions required
to address expanding users' needs.

     More recently, wireless technology developments have had an impact on the
telecommunications equipment industry.  There has been substantial growth in
wireless communications such as cellular telephone services and satellite-based
services, Personal Communications Services (PCS) communications, Multichannel
Multipoint Distribution Systems (MMDS) and Local Multipoint Distribution Systems
(LMDS) for wireless cable services and wireless data and paging services.  This
growth has been spurred by the convenience of mobility and the limits of
wireline infrastructure.  In particular, in countries without reliable or
extensive wireline systems, wireless service could ultimately provide the
primary service platform for both mobile and fixed telecommunications
applications, because of the potential savings in installation time and cost.
The Company believes that in future years the continuing development of wireless
communications technology could substantially extend the reach of current
communications networks.

     Finally, over the past two years, Digital Subscriber Line (DSL) technology
and Digital Loop Carrier (DLC) technology advancements have resulted in a
resurgence of copper-based transmission of high bandwidth services to business
customers.  The Company believes that in future years the continuing development
of DSL and DLC technologies could enable network providers to transport
residential broadband services over copper-based systems in certain
applications.

     Increased demand for new, higher speed, higher capacity services such as
Internet access, digital video and advanced wireless services has in turn
resulted in substantial demands on network infrastructure over the past decade.
Networks increasingly are required to transmit large volumes of data and video
for the purpose of communicating information, conducting business and delivering
entertainment.  In addition, both public and private network customers are
requesting the convergence of their voice, data and video traffic into
integrated multimedia services transmitted over one network.  Such demands have
prompted the development and use of "broadband" networks, which feature the
improved reliability and increased speed of transmission generally required for
data and video


                                          3
<PAGE>

transmission over the network.  Specifically, the industry term "broadband"
refers to all transmission speeds of T1 (1.544 million bits per second) and
higher.  Growth in broadband network applications has resulted in increased
infrastructure investment by network operators in order to expand network
capacity and provide new applications and services to meet users' needs.

     The evolution in technology and user needs has been accompanied by changes
in the domestic and international regulatory environment.  Since the divestiture
of the AT&T regional operating companies in 1984 (in a consent decree), the
RBOCs have been prevented from manufacturing equipment for use in
telecommunications networks.  As the RBOCs have embarked on aggressive expansion
plans, significant opportunities have been created for independent
telecommunications equipment manufacturers such as the Company.

     In February 1996, the U.S. Congress enacted the Telecommunications Reform
Act of 1996 (the "Telecommunications Act"), which opened competition for local
loop access services to local telephone companies, long distance telephone
companies, cable TV companies, electric utilities and potentially others.  The
Telecommunications Act represents a fundamental change from the Communications
Act of 1934, which governed the U.S. telephone industry structure prior to 1996
and which protected franchised monopolies in local telephone service.  The
Telecommunications Act also allows the RBOCs to provide long distance service
and manufacture telecommunications equipment under certain circumstances,
another significant change from the 1984 consent decree which required
divestiture of the AT&T regional operating companies.  The objective of the
Telecommunications Act is to reduce regulation and stimulate competition in
telecommunications services, which in turn is expected to result in more rapid
introduction of new technologies and services, better quality of service, a
broader range of service options, lower costs to consumers and stimulation of
the overall economy through an improved information system infrastructure.  The
Company believes that Congress intended for the competition among service
providers to be both services-based (i.e., the service provider buys and resells
bandwidth) and equipment-based (i.e., the service provider also operates the
equipment).

     Since the passage of the Telecommunications Act, the Federal Communications
Commission (FCC) and the federal courts, as well as various state governments
and agencies, have initiated efforts to define and establish rules for
implementation of the new law.  Although implementation of the
Telecommunications Act and the intended increase in competition has begun, there
have been a number of delays and continuing uncertainties. The Company believes
that the impact of the Telecommunications Act in reducing regulation of and
increasing competition in the U.S. telecommunications industry will take a
number of years to unfold.

     Outside the United States, the telecommunications equipment market has also
expanded and changed significantly in recent years, as network users have
increasingly demanded access to voice, data and video communications
capabilities.  Many countries without reliable or extensive wireline systems are
seeking to develop and enhance their telecommunications infrastructure.  This
growth in demand for network services and infrastructure has been accompanied by
changes in the international regulatory environment.  In many countries,
government operated telecommunications monopolies are being converted to private
network services providers, and competition among such carriers is expected to
intensify.  Policies of deregulation and privatization are currently being
followed in many countries, and these policies increase opportunities for
independent companies to supply products and services within public telephone
system markets and within private voice, data and video communications markets.

     The Company believes that "broadband global networking," or the emerging
series of worldwide broadband networks, represents a key enabling capability for
meeting the information needs of network users.  The addition of high speed data
and video traffic has driven the need for broadband


                                          4
<PAGE>

infrastructure and has enabled the creation of a wide range of new applications,
including broadband Internet access and e-mail, video on demand, electronic
commerce, distance learning, telecommuting, telemedicine and high speed imaging
such as remote medical imaging.  The Company participates in this emerging
broadband global network market by providing a broad variety of end-to-end
integrated equipment and services solutions.

STRATEGY

     ADC's strategy is to capitalize on opportunities in the evolving global
telecommunications market by providing equipment, services and integrated
systems solutions for its customers' voice, data and video telecommunications
networks primarily within the local loop area of the telecommunications market.
ADC's broad range of products addresses key areas of the telecommunications
network infrastructure, and these products are used to connect physical
networks, access network services, transport network traffic and manage
networks.  ADC's many product offerings address the diverse needs of its
customers within the local loop, including the RBOCs, PTT's, other telephone
companies, long distance carriers, wireless service providers, the major cable
TV operators, other public network providers, private network providers and
telecommunications OEMs.

Key components of the Company's strategy include:

- -    FOCUS ON BROADBAND LOCAL LOOP MARKET OPPORTUNITIES.  In recent years,
     broadband requirements for both public and private networks have grown
     significantly.  ADC offers a broad line of telecommunications equipment
     that addresses customers' network needs in the "local loop."  The Company
     believes that the local loop presents some of the greatest market growth
     opportunities and customer needs in the telecommunications equipment
     industry today, and is therefore focusing its product development and
     marketing efforts on these emerging opportunities.  Through internal
     development, acquisitions and joint ventures, ADC has organized its local
     loop offerings into three major network product areas: transmission,
     enterprise networking and broadband connectivity.  In addition, through a
     combination of internal core competency development and external
     acquisition and partnering activities, ADC has grown its systems
     integration and network management capabilities to the level required to
     offer customers much more complete, end-to-end solutions to their network
     needs.  ADC's local loop products and services enable network providers to
     address their three major broadband customer markets: residential, business
     and wireless.

- -    FOCUS ON BROADBAND TECHNOLOGIES THAT "UNLOCK THE CAPACITY OF THE LOCAL
     LOOP."  In the public network local loop market, broadband deployment has
     been driven by telephone and cable television providers seeking to
     establish the infrastructure required to offer Internet access,
     higher-speed data, video and telephony services, entertainment and other
     interactive services to residential customers over a single network.
     Broadband deployment in the public network local loop market has also been
     accelerated by telephone providers and competitive local exchange carriers
     seeking to establish a single network which will offer higher-speed voice,
     data and video services utilizing increasing amounts of bandwidth to
     business customers.  In addition, both residential and business customers
     are driving local loop network requirements by increasingly demanding
     advanced wireless services.  ADC is focusing its development resources on
     technologies that will "unlock the capacity of the local loop" (i.e.,
     eliminate bottlenecks and increase the speed and efficiency within the
     local loop).  Examples of products developed by ADC to target these local
     loop opportunities include the Company's Homeworx-TM- system, which has
     been designed to enable telephone and cable television companies to provide
     a range of voice, video and data services to residential customers; the
     Soneplex-Registered Trademark- product platform, which allows public
     network providers to cost effectively deliver and manage


                                          5
<PAGE>

     broadband services over the public network for their business customers;
     the AAC-3-TM- ATM access concentrator, which allows customers to gain
     access to high speed switched voice, data and video traffic on public
     networks from their private networks; television transmission products for
     the wireless cable and broadcast industry, which provide an alternative,
     wireless method of broadcasting video and other services to residential
     customers; and the Company's family of CityWide-TM- wireless systems, which
     provide access to, add to and extend wireless communications coverage.  In
     addition, ADC's 1997 acquisitions and joint ventures and internal product
     development efforts improved the Company's ability to target broadband
     local loop network opportunities.  See "SUPPLEMENT INTERNAL DEVELOPMENT
     EFFORTS WITH STRATEGIC ALLIANCES AND ACQUISITIONS"  in this section as well
     as the specific product group discussions below.

- -    LEVERAGE TECHNOLOGICAL CAPABILITIES ACROSS PRODUCT GROUPS.  ADC has
     developed substantial expertise in fiber optic, broadband copper, video,
     wireless and broadband network management technologies and systems
     integration services.  The Company has built these core competencies
     through internal development, acquisitions, joint ventures and technology
     licensing arrangements.  ADC's strategy is to leverage these core
     competencies across its product groups in order to develop new product
     architectures and network management tools for its customers' evolving
     voice, data and video network needs in various market areas.  For example,
     the Company is continuing development of its wireless technologies for use
     in converging wired and wireless applications, such as potential wireless
     local loop products.  See "SUPPLEMENT INTERNAL DEVELOPMENT EFFORTS WITH
     STRATEGIC ALLIANCES AND ACQUISITIONS"  in this section.

- -    EXPAND INTERNATIONAL PRESENCE.  ADC believes that significant growth in the
     telecommunications equipment market will occur outside the United States as
     a result of deregulation and the need of many foreign countries to
     substantially expand or enhance their telecommunications services.  During
     both 1997 and 1996, ADC's international sales represented approximately 21%
     of total sales, compared to 18% of total sales for 1995.  ADC's strategy is
     to continue to expand its international presence by increasing its
     international sales and marketing resources, leveraging its existing
     customer relationships, developing additional international distribution
     channels and seeking strategic alliances and acquisitions. Three of ADC's
     subsidiaries and several of its strategic alliance partners have their
     principal operations or markets outside the U.S.

- -    SUPPLEMENT INTERNAL DEVELOPMENT EFFORTS WITH STRATEGIC ALLIANCES AND
     ACQUISITIONS.  Because of the dynamic nature of the telecommunications
     equipment industry, ADC has sought and intends to continue to seek
     alliances and acquisitions which will: (i) add key technologies that ADC
     can leverage across its businesses, (ii) broaden its product offerings,
     (iii) permit the Company to enter attractive new markets and (iv) expand or
     enhance its distribution channels.  Recent examples of such alliances and
     acquisitions include:  (i) the acquisition of The Apex Group, Inc., a
     software development and information management company based in Columbia,
     Maryland; (ii) the acquisition of NewNet, Inc., a developer of intelligent
     network telecommunications software, including Signaling Systems 7 (SS7)
     technology and wireless intelligent network products (such as short
     messaging servers), located in Shelton, Connecticut; and (iii) the 
     marketing and development agreement with interWAVE Communications 
     International, Ltd. of Redwood City, California, under which ADC is 
     marketing interWAVE's line of Global System for Mobile Communications (GSM)
     system products worldwide.

     The ability of the Company to implement its strategy effectively is subject
to many uncertainties, and there can be no assurance of any future results of
the Company's activities.

PRODUCT GROUPS

     The Company's products can be categorized into three general functional
groups: (i) transmission, (ii) enterprise networking and (iii) broadband
connectivity.  These product groups accounted for 44%, 13% and 43%,
respectively, of the Company's net sales during 1997.  Each of these product
groups is discussed below.

TRANSMISSION PRODUCTS

     ADC's transmission products provide electronic and optical signal
generation primarily within the local loop portion of public networks.  Certain
of the transmission products also provide access to the network in order to
monitor, test and reroute circuits within telecommunications transmission
systems.  ADC's transmission products are designed for use in copper-based,
coax-based, fiber-based or wireless transmission networks and are sold to
telephone companies, cable TV companies, other public network providers and to
users of private voice, data and video networks.  Transmission products and
services include fiber optic video delivery products, other high speed voice,
data and video delivery and access platforms, wireless cable and broadcast TV
transmission equipment, wireless microcell systems, wireless performance and
network management systems, test and monitoring systems, digital repeaters and
systems integration services and products.  The Company's principal transmission
products are described below.

DV6000-TM- AND OTHER FIBER VIDEO DELIVERY EQUIPMENT.  The Company's DV6000
system transmits a variety of signal types using a high speed, uncompressed
digital format (at speeds up to 10 billion bits per second, with capacity of up
to 64 channels) over fiber in the super trunking portions of broadcast and
interactive video networks.  This system is used in public residential broadband
networks.  During 1997, ADC added Ethernet-based data transport capabilities to
the DV6000 platform.  The Company also manufactures various analog video
transmission systems used in cable TV and broadcast applications and interactive
systems for distance learning and campus interconnects.

HOMEWORX ACCESS TRANSPORT PLATFORM.  The Company's Homeworx access transport
platform is a customer loop transmission system for small business and
residential customers utilizing Hybrid Fiber Coax (HFC) technology.  The
Homeworx system has been designed for deployment on video-only, telephony-only
and integrated video, telephony and data broadband networks provided by
telephone operating companies, cable TV companies and other telecommunications
common carriers.  In October 1997, NetCom Systems AB, a major alternative
provider of telecommunication services in Scandinavia, selected ADC's Homeworx
telephony equipment to deliver enhanced telephony and data services over its
existing cable TV HFC infrastructure to certain of its 320,000 customers at
Tele2, NetCom's telephony operator in Sweden.  In December 1997, MediaOne began
deploying the Homeworx system for a major telephony network in Atlanta, Georgia.
In mid-1998, the Company expects to begin a limited number of customer test
trials for the symmetrical cable data modem portion of the Homeworx system which
was developed with another company.  In addition, the Company recently announced
an asymmetrical cable data modem product obtained through a marketing and
development agreement with Phasecom.  The Company currently plans to begin
shipping commercial volumes of the asymmetrical cable data modem products in the
first half of 1998.  Finally, ADC has undertaken development of a High bit-rate
Digital Subscriber Line (HDSL) platform, a wireless broadband access platform
and an integrated wireless/wireline narrowband access platform for residential
network applications.  These three new systems, all of which are based on the
Homeworx platform, provide an example of ADC's ability to leverage technology
developments into related applications.  The Company anticipates that these
systems will be available for customer test trials by the end of 1998.

SONEPLEX SERVICE DELIVERY PLATFORM.  The Company's Soneplex platform is a
carrier-class, intelligent loop access platform enabling public network
providers to deliver T1/E1 based services to business customers.  The Company's
Soneplex family of platforms employs various transport technologies, including
fiber optic and High bit-rate Digital Subscriber Line (HDSL) transmission, to
deliver high-bandwidth voice, data and video services over carriers' fiber and
copper facilities.  Soneplex systems utilize integrated network management to
provide remote circuit provisioning, visibility and sectionalization, helping to
decrease the operating costs of public network delivery of T1/E1 services.  The
integrated multiplexing capability of ADC's Soneplex platform also provides
public network carriers a more efficient inter-connection and direct interface
to their high-speed SONET core network.  During 1997, ADC's Soneplex system was
approved for use at Bell Atlantic, GTE, Pacific Bell, Teleport Communications
Group, Hong Kong Tel, Hutchison Telecommunications and  Shaw FiberLink.  The
Company continues to introduce new modules and capabilities for the Soneplex
platform.  During 1998, the Company plans to enhance the Soneplex system to
include much higher SONET speeds and international interfaces.  Also, during
1998, the Company expects to enter customer test trials of its Cellworx system.
The Cellworx system is ADC's ATM based, very high-speed, intelligent platform
enabling public network providers and enterprise networks to deliver ATM and
SONET based services to business customers over copper and fiber facilities.

WIRELESS CABLE/BROADCAST TELEVISION TRANSMISSION EQUIPMENT. The Company
participates in the wireless cable and television broadcast market through its
subsidiary, Information Transmission Systems Corp. ("ITS").  ITS designs and
manufactures television transmission products for these markets, including
transmitters, combiners, back-up equipment and antennas to wireless cable
operators for MMDS.  ITS's wireless products have enabled ADC to leverage the
Homeworx platform into other residential broadband applications.

CITYWIDE-TM- PRODUCTS.  The Company's family of CityWide wireless systems
products includes the CityCell-Registered Trademark- and CityLink-Registered
Trademark- wideband digital microcells and repeaters for adding and extending
cellular communication coverage, both out-of-doors and in-building.  The
CitySector-Registered Trademark- microcell is the first fully sectorized
microcell offering 25 to 100 watts of Radio Frequency (RF) power per sector.
Fully transparent to analog or digital modulation, the CityWide products have
been commercially deployed by five of seven major U.S. cellular network
providers  The Company's new analog wideband CityCell microcell utilizes T1
copper transport rather than fiber transport.  The Company has under development
PCS versions of its CityRFX-Registered Trademark- cellular indoor antenna
distribution systems.  The Company also offers advanced intelligent network
solutions for its CityWide product family with the CityLink CDMA and GSM
repeaters.

OTHER CELLULAR AND PCS TRANSMISSION EQUIPMENT.  During 1997, the Company entered
into a marketing and development agreement with interWAVE Communications
International, Ltd., in which ADC began marketing interWAVE's line of GSM system
products worldwide.  In addition, ADC provides systems level design  and

wireless infrastructure equipment and subsystems, broadband software
infrastructure management systems and systems integration services.  The
Company's principal broadband connectivity products are described below.

JACKS, PLUGS, PATCH CORDS, JACKFIELDS AND PATCH BAYS.  Jacks and plugs are the
basic components used to gain access to copper telecommunications circuits for
testing and maintenance.  Patch cords are wires or cables with a plug on each
end.  ADC incorporates its jacks, plugs and patch cords into its own products
and also sells them in component form, primarily to OEMs.  A jackfield is a
module containing an assembly of jacks wired to terminal blocks or connectors
and used by telecommunications companies to gain access to copper communication
circuits for testing or patching the circuits.  When testing a large number of
circuits, series of jackfields are combined in specialized rack assemblies
called patch bays.  ADC manufactures a range of jackfields and patch bays in
various configurations.  Certain of these jackfields are specialized for use in
audio and visual transmission networks in the broadcast industry.

DSX PRODUCTS.  ADC manufactures digital signal cross-connect (DSX) modules and
bays, which are jackfields and patch bays designed to gain access to and
cross-connect digital copper circuits for voice, data and video transmission.
Since the introduction of DSX products in 1977, the Company has continued to
expand and refine its DSX product offerings.  The Digital Distribution Point
(DDP) family of products within the DSX product group are mechanical
alternatives to hard-wiring equipment used for cable management and circuit
access with software based, electronic digital cross-connect systems.

TERMINAL BLOCK AND FRAME PRODUCTS.  ADC manufactures a wide variety of terminal
blocks which are molded plastic blocks with contact points used to facilitate
multiple wire interconnections.  The Company's cross-connect frames are terminal
block assemblies used to connect the external wiring of a telecommunications
network to the internal wiring of a telephone operating company central office
or to interconnect various pieces of equipment within a telephone company
central office or at a customer's premise.

VIDEO SIGNAL DISTRIBUTION PRODUCTS.  ADC's series of Video Signal Distribution
(VSD) products are designed to meet the unique performance requirements of Radio
Frequency (RF) video transmission over coax cable.  This product family includes
a series of splitter/combiner panels, a series of video jacks and


                                          10
<PAGE>

panels which monitor, patch and provide a test access point and an analog video
interface system panel designed for on-demand testing.

OTHER FIBER OPTIC PRODUCTS.  Fiber optic patch cords are functionally similar to
copper patch cords and are the basic components used to gain access to fiber
telecommunications circuits for testing, maintenance, cross-connection and
configuration purposes.  The Company's LightTracer-TM- fiber optic patch cords
provide immediate identification of fiber optic connections.  The Company
incorporates its fiber optic patch cords and cable assemblies into its own
products and also sells them in component form. ADC's subsidiary AOFR Pty. Ltd.,
located in Australia, sells fiber optic couplers which are passive connection
devices used in fiber optic transmission systems which conform to the stringent
environmental, reliability, performance and mechanical standards required in
global broadband network and test equipment markets.  These products, which
include optical splitters and wavelength division multiplexers, enable efficient
and cost-effective deployment of broadband networks.  The Company's fiber
distribution panels and frames are functionally similar to copper jackfields and
frames designed with special considerations of fiber optic properties.  They
also provide interconnection points between fiber optic cables entering a
building and fiber optic cables connected to fiber optic equipment within the
building.  ADC also sells Dense Wave Division Multiplexing (DWDM) Components
such as splitters and multiplexers which are designed with special
considerations of fiber optic properties.  These products increase the channel
capacity of fiber optic cabling systems in multiples of four.  ADC currently is
selling four-channel and eight-channel components and has recently introduced
sixteen-channel components.  The Company's FiberGuide-Registered Trademark-
system is a modular routing system which provides a segregated, protected method
of storing and routing fiber patch cords and cables within buildings.

WIRELESS INFRASTRUCTURE EQUIPMENT AND SUBSYSTEMS.  ADC designs, manufactures and
markets radio frequency filters, tower-top amplifiers and other wireless base
station and subscriber equipment components and subsystems through its
subsidiary Solitra Oy subsidiary located in Finland.  These products are sold
primarily to wireless OEMs.

BROADBAND SOFTWARE INFRASTRUCTURE MANAGEMENT  SOLUTIONS.  ADC has developed a
number of software products which provide management of fiber optic
infrastructure connectivity, geographical tracking of equipment, cables and
other network elements in the telephone company central office, cable TV company
headend  and outside plant portion of those networks.

SYSTEMS INTEGRATION SERVICES.  The Company's systems integration services
relating to the Company's broadband connectivity product group are divided into
three areas: technical service design and management; operations and
implementation; and training and documentation services.   These services
usually consist of layout and installation of new telecommunications networks,
modification of existing networks or the addition of equipment to existing
networks.  The Company provides its systems integration services primarily to
telephone operating companies, other common carriers and users of private
telecommunications networks.

SALES AND MARKETING

     ADC sells its products to customers in three primary markets: (i) the
United States public telecommunications network market, which consists of all
five of the RBOCs, other telephone companies, long distance carriers, wireless
service providers, the major cable TV operators and other domestic public
network providers; (ii) the private and governmental voice, data and video
network market in the United States, such as various large business customers
and governmental agencies that own and operate their own voice, data and video
networks for internal use; and (iii) the international public and private
network market.  The U.S. public, U.S. private and governmental and
international


                                          11
<PAGE>

market segments accounted for 73%, 6% and 21%, respectively, of the Company's
net sales for the year ended October 31, 1997; 71%, 8% and 21%, respectively,
of the Company's net sales for the year ended October 31, 1996; and 74%, 8% and
18%, respectively, of the Company's net sales for the year ended October 31,
1995.  The Company also sells product for each of these customer groups to the
major telecommunications OEMs.

     Purchases of products by public network providers and the OEMs which supply
such companies accounted for the largest portion of the Company's net sales.
The Company's transmission and broadband connectivity products for public
network providers are primarily located in central transmission facilities (such
as telephone company network central offices, cable TV company network
supertrunks and headend offices, and wireless network global switching centers
and base stations, all of which contain the equipment used in switching and
transmitting incoming and outgoing circuits).  Increasingly, portions of the
Company's public network transmission systems are located in the public network
outside plant facilities (outside the central transmission buildings) and on
customers' premises.  The Company's private and governmental network customers
generally purchase the Company's enterprise-wide communications systems and
public network access equipment for installation in the networks located at
their premises.

     The Company also markets its products outside the United States primarily
to telephone operating companies and cable TV companies for public
telecommunications networks located in Canada, Europe, the Pacific Rim,
Australia and Central and South America.

     A majority of the Company's sales are made by a direct sales force, and the
Company maintains sales offices throughout the United States as well as in
Canada, Europe, the Pacific Rim, Australia and Central and South America.  The
Company's products are sold in the United States by several sales offices
located throughout the country, as well as through dealer organizations and
distributors.  The Company's products are sold outside the United States by
several field sales offices and by independent sales representatives and
distributors, as well as through United States public and private network
providers who also distribute outside the United States.

     The Company has a customer service group that supports field sales
personnel and is responsible for application engineering, customer training,
entering orders and supplying delivery status information, and a field service
engineering group that provides on-site service to customers.

RESEARCH AND DEVELOPMENT

     The Company believes that its future success depends on its ability to
adapt to the rapidly changing telecommunications environment, to maintain its
significant expertise in core technologies and to continue to meet and
anticipate its customers' needs.  The Company continually reviews and evaluates
technological changes affecting the telecommunications market and invests
substantially in applications-based research and development.  The Company
intends to continue an ongoing program of new product development that combines
internal development efforts with acquisitions, joint ventures and licensing or
marketing arrangements relating to new products and technologies from sources
outside the Company.

     In recent years, increasingly significant portions of new
telecommunications equipment purchased by public network providers and private
network customers have employed fiber optic transmission, digital, integrated
circuit, wireless and broadband copper-based technologies for residential,
business and wireless local loop applications.  In the future, these
telecommunications network equipment purchasing trends will include increasingly
sophisticated, software-intensive, switching and network management systems.  As
a result, the Company's internal and external product


                                          12
<PAGE>

development activities are primarily directed at the following areas:  (i) the
integration of fiber optic technology into additional products; (ii) the
continuing development of its Homeworx system for telephony, data and integrated
video, telephony and data applications; (iii) the development of network systems
software; (iv) the continuing development of its Soneplex and Cellworx systems
for integrated voice, data and video applications; (v) the continuing
development of wireless products; (vi) the incorporation of ATM technology into
voice, data and video products for both public and private telecommunications
networks; and (vii) the addition of video compression technology to its product
line.

     New product development often requires long-term forecasting of market
trends, development and implementation of new processes and technologies and a
substantial capital commitment.  As a result of these and other factors,
development and customer acceptance of new products is inherently uncertain, and
there can be no assurance that such products will be developed on a timely basis
or achieve market acceptance.

COMPETITION

     Competition in the telecommunications equipment industry is intense, and
the Company believes that competition may increase substantially with the
deployment of broadband networks and regulatory changes.  Many of the Company's
foreign and domestic competitors have more extensive engineering, manufacturing,
marketing, financial and personnel resources than those of the Company.  The
Company's transmission products are competitive with products offered by several
other companies, including Lucent Technologies, Northern Telecom, Inc.  and
Motorola, Inc.  The Company's enterprise networking products are competitive
with the products of a number of other companies.  Both the Company's
transmission and enterprise networking products face strong price competition
and pressure from alternative distribution strategies utilized by other
companies.  The Company's broadband connectivity products are competitive with
the products offered by numerous other companies, including Lucent Technologies,
Siecor Corporation and Telect Inc.  In addition, the Company faces increasing
competition from a number of other smaller competitors, none of which is
dominant at this time.

     The rapid technological developments within the telecommunications industry
have resulted in frequent changes to the Company's group of competitors.  The
Company believes its success in competing with other manufacturers of
telecommunications products depends primarily on its engineering, manufacturing
and marketing skills, the price, quality and reliability of its products and its
delivery and service capabilities.  While the market for the Company's products
has not historically been characterized by significant price competition, the
Company may face increasing pricing pressures from current and future
competitors in certain or all of the markets for its products.

     The Company believes that technological change, the increasing addition of
data, video and other services to integrated multimedia networks, continuing
regulatory change and industry consolidation or new entrants will continue to
cause rapid evolution in the competitive environment of the telecommunications
equipment market, the full scope and nature of which are difficult to predict at
this time.  Increased competition could result in price reductions, reduced
margins and loss of market share by the Company.  The Company believes industry
regulatory change may create new opportunities for suppliers of
telecommunications equipment.  The Company expects, however, that such
opportunities may attract increased competition from others as well.  In
addition, the Company expects that Lucent Technologies will continue to be a
major supplier to the RBOCs, and compete more extensively outside the RBOC
market.  The Company also believes that the rapid technological changes which
characterize the telecommunications industry will continue to make the markets
in which the Company competes attractive to new entrants.  There can be no
assurance that the Company


                                          13
<PAGE>

will be able to compete successfully with its existing or new competitors or
that competitive pressures faced by the Company will not materially and
adversely affect its business, operating results or financial condition.

MANUFACTURING AND SUPPLIES

     The Company manufactures a wide variety of products which are fabricated,
assembled and tested in its own facilities or in subcontracted facilities.  In
an effort to reduce costs, the Company also takes advantage of off-shore
assembly and sourcing.  The manufacturing process for the Company's electronic
products consists primarily of assembly and testing of electronic systems built
from fabricated parts, printed circuit boards and electronic components.  The
manufacturing process for the Company's electromechanical products consists
primarily of fabrication of jacks, plugs, and other basic components from raw
materials, assembly of components and testing.  The Company's sheet metal,
plastic molding, stamping and machining capabilities permit the Company to
configure components to customer specifications.

     The Company purchases raw materials and component parts, consisting
primarily of copper wire, optical fiber, steel, brass, nickel-steel alloys,
gold, plastics, printed circuit boards, solid state components, discrete
electronic components and similar items, from several suppliers.  Although a few
of the components used by the Company are single sourced, the Company has
experienced no significant difficulties to date in obtaining adequate quantities
of these raw materials and component parts.  This circumstance could change in
the future, however, and the Company cannot be sure that the quantity or quality
of raw materials and component parts will be as readily available in the future.

PROPRIETARY RIGHTS

     The Company owns a number of United States and foreign patents relating to
its products.  These patents, in the aggregate, constitute a valuable asset of
the Company.  The Company, however, believes that its business is not dependent
upon any single patent or any group of related patents.

     The Company has registered the initials ADC alone and in conjunction with
specific designs as trademarks in the United States and various foreign
countries.

EMPLOYEES

     As of October 31, 1997, there were approximately 5,924 persons employed by
the Company.  The Company considers relations with its employees to be good.

                          EXECUTIVE INCENTIVE EXCHANGE PLAN
                                   FISCAL YEAR 1998


I.    PLAN NAME AND EFFECTIVE DATE

The name of this Plan is the ADC Telecommunications, Inc. ("Company") Executive
Incentive Exchange Plan - Fiscal Year 1998 ("FY 1998"), effective November 1,
1997 through October 31, 1998.

II.   PURPOSE

The purpose of the Plan is to provide exceptional rewards for exceptional
performance of eligible executives, align executive rewards with shareholder
interests, and provide an incentive for retention.

III.  ADMINISTRATION

This Plan will be administered by the same Committee ("Committee") appointed and
authorized by the Company's Board of Directors to administer the Company's 1991
Stock Incentive Plan.  The Committee is authorized to make all decisions as
required in administration of the Plan and to exercise its discretion to define,
interpret, construe, apply, and make any exceptions to the terms of the Plan.

IV.   STOCK OPTION ISSUANCE

All stock options issued under this Plan will be granted under the Company's
1991 Stock Incentive Plan and/or its successor plans.

V.    ELIGIBILITY

The Committee will establish rules of eligibility for participation in the Plan
in accordance with the 1991 Stock Incentive Plan and determine eligibility in
accordance with those rules. Eligibility is limited to those Corporate and
Divisional Vice Presidents in salary grade 19 or above who receive approval from
the Chief Executive Officer for participation in the Fiscal Year Plan.  A
limited number of selected additional executives may be included also as
approved by the Chief Executive Officer.  All Plan participants must also be
participants under the Company's Management Incentive Plan ("MIP").

VI.   PLAN GOALS AND ACHIEVEMENT

All goals and objectives under this Plan shall be identical to the goals and
objectives stated in each participant's MIP.  Total payouts are calculated in
the same fashion as payouts made under the applicable MIP.

<PAGE>

VII.  EXCHANGE ELECTION

Prior to the beginning of FY 1998, participants may irrevocably elect to
exchange up to 50% of their FY 1998 MIP award for options to purchase common
stock of the Company.  Such elections may be made in 10% increments up to a
maximum of 50% of the cash MIP award.  Participants hired or promoted into a
position eligible for this Plan during FY 1998 may make this election up to 30
days following the date of hire or promotion.  No election may be made after May
1, 1998 by new hires or newly promoted eligible participants.  No exchange will
be made if the portion elected for exchange is less than One Hundred Dollars
($100.00).

VIII. EXCHANGE DATE

Exchanges made under this Plan will be made as soon as administratively feasible
following the close of FY 1998 and as soon as MIP awards are approved.  The
exchange date will be the same day as the MIP awards are approved.  For purposes
of this document, the terms exchange date and grant date are synonymous.

IX.   EXCHANGE CALCULATION

The MIP award that will be used to calculate the exchange to options will be the
incentive amount eligible to be paid for the fiscal year excluding any amounts
allocated to bonus bank accounts as defined in the Management Incentive Plan.

The dollar amount of the MIP award elected to be exchanged will first be
multiplied by an exchange factor ("Factor") of six (6).  This amount is then
divided by the Black-Scholes value of an option to purchase one share of ADC
common stock on the last day of FY 1997 to determine the number of option shares
to be received by the participant.  

This Black-Scholes value will reflect the vesting characteristics of the options
to be granted under this Plan and other characteristics as appropriate, and as
such may differ from the Black-Scholes value applied for other options granted
under other Company plans.  The final number of shares will be rounded down if
necessary to the nearest whole share.

This exchange causes payment of the MIP cash incentive amount exchanged to be
forfeited, except as described under Section XIII.

X.    NATURE OF OPTIONS TO BE GRANTED

All options granted under this Plan will be nonqualified stock options, that are
not "incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended.

<PAGE>

XI.   TERM AND VESTING OF OPTIONS

All options granted under this Plan will have a term and method of exercise as
determined by the Committee.  The term will be 10 years from the date of
exchange or grant.  Options will vest in three (3) equal annual installments,
beginning one (1) year after the grant date.

XII.  EXERCISE PRICE OF OPTIONS

The exercise price of the stock options granted under this plan will be the Fair
Market Value of the Company's common stock on the last business day of the
fiscal year and be determined in accordance with the 1991 Stock Incentive Plan.

XIII. EFFECT OF CHANGE IN EMPLOYMENT STATUS ON CURRENT YEAR ELECTIONS (CHANGES
      DURING THE PLAN YEAR)

A.    VOLUNTARY RESIGNATION OR INVOLUNTARY TERMINATION.  A participant who
      voluntarily resigns employment or who is terminated involuntarily, except
      as defined under paragraph B below, prior to the end of FY 1998 will
      relinquish all rights to the grant of any stock option under this plan.

B.    TERMINATION OF EMPLOYMENT BASED UPON JOB ELIMINATION.  Subject to the
      approval of the Committee, a participant who is involuntarily terminated
      because of a job elimination may receive a cash equivalent calculated in
      the same fashion as the applicable pro-rata cash MIP payment would be
      made (not subject to the Factor), provided at least three months was
      served in the eligible position.

C.    CHANGE IN JOB STATUS BASED UPON A PROMOTION/DEMOTION.  A participant who
      is demoted from an eligible position under this Plan to an ineligible
      position will exchange the pro-rata portion of cash MIP award that is
      calculated according to the time served in the eligible position during
      FY 1998, provided at least three months was served in the eligible
      position.  A participant who is promoted into an eligible position under
      this Plan will be provided the opportunity to exchange the pro-rata MIP
      award that is calculated according to the time served in the eligible
      position under this Plan during FY 1998, as provided in Section VII of
      this document, based upon the exchange percentage elected by the
      participant.

D.    DEATH.  If a participant dies during FY 1998, the participant's heirs as
      determined by will or applicable laws of descent and distribution will
      have no right to receive any stock options under this plan.  Heirs will
      receive instead the cash equivalent of the pro-rata MIP award that is
      calculated according to the MIP Plan, but not subject to the Factor.

<PAGE>

XIV.  EFFECT OF CHANGE IN EMPLOYMENT STATUS OCCURRING AFTER FY 1998 ON
      EXCHANGES MADE IN FY 1998

All stock options already awarded under this Plan will vest fully upon a
participant's death, disability, or voluntary retirement.  For purposes of this
Plan, retirement from the Company shall be defined as having attained age 55
with 10 years of service with the Company ("early retirement"), or age 65 with 5
years of service with the Company ("normal retirement").

If a participant terminates for any other reason, termination provisions will be
applied.  For each grant or exchange already made, if the participant terminates
prior to the vesting of the first one third of the options, all options and the
MIP cash equivalent amount will be immediately forfeited.  If the participant
terminates after the first one third of the options have vested, all vested
options will remain exercisable for a period of one (1) year.  All unvested
options will be forfeited, and no cash equivalent will be provided.

XV.   EFFECT OF CHANGE IN CONTROL ON EXCHANGES ALREADY MADE

In the event of a change in control of the Company as referenced in  stock
option agreements issued pursuant to this Plan, all unvested options will
immediately vest in full.

                                   FISCAL YEAR 1998


I.  PLAN NAME AND EFFECTIVE DATE

The name of this Plan is the ADC Telecommunications, Inc. ("Company"), Business
Development Management Incentive Plan - Directors and Above, Fiscal Year ("FY")
1998, effective November 1, 1997 through October 31, 1998.

II.  PURPOSE

The purpose of the Plan is to provide, with full regard to the protection of
shareholder's investments, a direct financial incentive for eligible employees
to perform an effective leadership role and make a significant contribution to
the Company's established goals.

III.  ADMINISTRATION

This Plan is administered by a Management Incentive Plan Committee ("Committee")
appointed and authorized by the Company's Board of Directors.  Subject to the
complete and full discretion of the Board of Directors, the Committee is
authorized to make all decisions as required in administration of the Plan and
to exercise its discretion to define, interpret, construe, apply and make any
exceptions to the terms of the Plan.

IV.  ELIGIBILITY

The Committee establishes rules of eligibility for participation in the Plan and
determines eligibility in accordance with those rules.  For Fiscal Year 1998,
eligibility applies to all employees in Grades 18 and above, plus any Grade 16
and 17 directors.  Participation is effective as of the date approved by the
Committee and is communicated to the participant by an incentive opportunity
statement ("Participant Form") specifying the target incentive level for the
position.  No employee will become a participant in the Plan after May 1, 1998,
unless the employee is already a participant in the Management Incentive Plan
for Managers.

<PAGE>

V.  PLAN GOALS

The Plan reinforces the key financial goals which support ADC's long-term
strategic plans.  The FY 1998 goal categories and weights for Business
Development participants are as follows:


                GOAL                                     WEIGHT
                ----                                     ------
*         Business Development EVA Improvement             50%
*         Corporate EVA Improvement                        30%
**        Individual Contribution                          20%
                                                         -----
          TOTAL                                           100%

*    EVA Improvement is the dollar amount of planned year-over-year improvement
     in EVA.  EVA Improvement goals are set for each of the next 3 years.

**   The Individual Contribution goal measures your performance against
     pre-determined objectives.  The objectives are to be documented on the
     attached "Individual Objective" form and require your Supervisor's and
     Division head's approval.

VI.  INCENTIVE PAYOUT OPPORTUNITIES

A.  The payout opportunity for meeting the Individual Contribution goal is as
    follows:

                                                     PAYOUTS
                                    -------------------------------------------
          GOAL                         THRESHOLD      TARGET       MAXIMUM
          ----                         ---------      ------       -------
          Individual Contribution     0% of Target     100%     200% of Target

      Results between threshold-target and target-maximum are interpolated.

B.   The payout opportunity for meeting the EVA Improvement goals are as
     follows:

          GOAL                         THRESHOLD      TARGET       MAXIMUM
          ----                         ---------      ------       -------
          EVA Improvement                N/A           100%          N/A
                                 (unlimited downside)         (unlimited upside)

     Incentive amounts are interpolated based on leverage (the slope of the
     line). 

     There are no thresholds and maximums for the EVA Improvement goals. 
     However, the specific incentive payout is a function of a bonus bank
     concept which is described in Section VII and Section VIII.

<PAGE>

VII.  BONUS BANK DEFINITION

As mentioned earlier, the Plan offers unlimited upside and downside rewards to
participants for creating value.  In order to ensure that EVA Improvements are
sustainable over a multi-year period, a bonus bank is created whereby
exceptional performance (above 200% of target) is credited to your account and
poor performance (negative amounts below 0% of the target level) is deducted
from your account.

The specific mechanics of the bonus bank are described below.

VIII.  HOW THE BONUS BANK WORKS

A.   A bonus bank account is created when the EVA Improvement goal achievement
     is above 200% of target or below 0% of the target level.

B.   Amounts achieved in excess of 200% of target are put into an EVA
     Improvement bonus bank.  These amounts vest at a rate of 25% per year,
     beginning immediately, and then after 1 year, 2 years, and 3 years,
     respectively.

C.   If EVA Improvement is less than 0% of the target level for the current Plan
     year, a negative amount is calculated and is handled as follows:

          1.  If there is a positive current year bonus bank amount, the
          negative amount offsets it.  After the negative has been applied, any
          positive vested amount is paid.  If the bonus bank is negative at the
          end of the year, the negative amount is carried over to the next 
          year.

          2.  If no positive bank balances have been carried forward from prior
          year(s), the entire negative amount goes into the bonus bank and is
          carried forward into the next plan year.  Then, in that next Plan
          year, if EVA Improvement is positive, the negative amount offsets
          amounts earned in that year in this manner and order:

               a)  Up to 100% of target achieved:  No reduction or offset. 
               Amount is paid immediately.

               b)  Between 100% and 200% of target.  Offset applies before any
               payout occurs.  The remaining amount, if any, is paid
               immediately.

               c)  Over 200% of target:  Offset applies before any amounts are
               banked and subject to vesting.   Any remaining amounts are
               subject to vesting schedule described above.

D.  The bonus bank is a bookkeeping account and as such, amounts allocated to a
    participant's bonus bank earn no interest, are unfunded, and do not
    actually vest until they are paid out in in accordance with the Plan.

<PAGE>

IX.  MAXIMUM EVA IMPROVEMENT GOAL PAYOUT IN ANY PLAN YEAR

Notwithstanding the above, the maximum amount that may be paid in any one year
to a participant due to the EVA Improvement goal, including amounts achieved for
the current year and bonus bank amounts that vest in the current year, may not
exceed 400% of the EVA Improvement target incentive amount.

X.  CURRENT PLAN YEAR PAYMENT

Payments which become due and payable under this Plan for the current Plan year
include:

- -    The amount achieved for the Individual Contribution goal, PROVIDED 0% OF
     THE TARGET LEVEL FOR ONE OF THE EVA IMPROVEMENT GOALS ARE MET.

- -    Current year EVA Improvement goal achievement up to 200% of target (if
     there are no negative offsets).

- -    Vested amount of EVA Improvement bonus bank account balance.

Payments which become due and payable under this Plan are made as soon as
administratively feasible following the close of the Company's Fiscal Year.

XI.  CALCULATION OF INDIVIDUAL PAYMENTS AND BONUS BANK ACCOUNT BALANCES

A.   The obligation to make payments under the Plan is determined by achievement
     of goals as determined by the Board of Directors.

B.  Calculations under this Plan are a function of:

          1.   Target incentive opportunity - expressed as a percentage of an
               individual's FY 1998 earnings.  The target % for each participant
               is designated on the "Participant Form."

          2.   Participant's 1998 Fiscal Year base salary earnings.

          3.   Performance against the established goals.

C.  Individual award calculations are shown by the following examples:

XII.  EFFECT OF CHANGE IN EMPLOYMENT STATUS

A.  VOLUNTARY RESIGNATION AND RETIREMENT.  A participant who voluntarily resigns
full-time employment or retires prior to the end of the Fiscal Year receives no
payment under the Plan for the current Plan year's performance or any EVA bonus
bank account balances being carried over.  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year. 

B.  CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
involuntarily terminated or transferred to a position not eligible for this Plan
for reasons of unsatisfactory job performance receives no payment under the Plan
for the current Plan year's performance or any EVA bonus bank account balances
being carried over from prior Plan year(s).  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year.

C.  CHANGE BASED UPON JOB ELIMINATION. Subject to the approval of the Committee,
a participant who is involuntarily terminated or transferred to a position not
eligible for this Plan or another Management Incentive Plan because of a job
elimination may retain the right to a pro rata calculation under this Plan for
the current year's performance, plus a pro rata portion of any EVA bonus bank
balance that would otherwise have vested at the end of the current Plan year,
based upon the time served in the eligible position during the Fiscal Year,
provided at least three months was served in the eligible position.  Rights to
any unvested EVA bonus bank account balances at the end of the Plan year are
forfeited.  The participant does not have any obligations with respect to any
negative EVA bonus bank account balances that remain after the pro rata
calculation.  

D.  CHANGE BASED UPON PROMOTION, DEMOTION, OR TRANSFER TO ANOTHER ELIGIBLE PLAN
JOB.  A current participant who is promoted, demoted, or transferred from an
eligible position under this Plan to another eligible position under this Plan
during the Fiscal Year has a pro rata calculation of the current year's
performance awards based upon the time served in each position during the Fiscal
Year, provided at least three months were served in each position.  If a
participant is in an eligible position for less than three months during the
Fiscal Year, the payment calculation is based on the incentive level of the
position served in the longest.  Any positive or negative bonus bank accounts
transfer with the individual in their entirety.

E.  CHANGE IN JOBS WITHIN THE COMPANY BUT NOT ELIGIBLE FOR THIS PLAN.  A
participant who changes jobs within the Company but is not eligible for this
Plan, retains the right to a pro rata payout under this Plan for the current
year's performance, plus a pro rata portion of any EVA bonus balance that would
otherwise have vested at the end of the current Plan year, based upon the time
served in the eligible position during the Fiscal Year, provided at least three
months was served in the eligible position.  Rights to any unvested EVA bonus
bank account balances at the end of the Plan year are forfeited.  The
participant does not have any obligations with respect to any negative EVA bonus
bank account balances that remain after the pro rata calculation.

<PAGE>

F.  DEATH.  If a participant dies during the Fiscal Year, the participant's
heirs as determined by will or applicable laws of descent and distribution will
have a pro rata calculation of the current year's performance, plus a pro rata
portion of any EVA bonus bank balance that would otherwise have vested at the
end of the current Plan year, based upon the time served in the eligible
position during the Fiscal Year.  Rights to any unvested EVA bonus bank account
balances at the end of the current Plan year are forfeited.  The participant's
heirs do not have any obligations with respect to any negative EVA bonus bank
account balances that remain after the pro rata calculation.

XIII.  COMPLIANCE WITH SECTION 162(M) OF THE INTERNAL REVENUE CODE OF 1986

If a current Plan year payout causes the participant's total cash compensation
to exceed one  million dollars in the Fiscal Year, the participant must defer
the portion that exceeds the one million dollars in the ADC Telecommunications
Deferred Compensation Plan.

XIV.  AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

to perform an effective leadership role and make a significant contribution to
the Company's established goals.

III.  ADMINISTRATION

This Plan is administered by a Management Incentive Plan Committee ("Committee")
appointed and authorized by the Company's Board of Directors.  Subject to the
complete and full discretion of the Board of Directors, the Committee is
authorized to make all decisions as required in administration of the Plan and
to exercise its discretion to define, interpret, construe, apply and make any
exceptions to the terms of the Plan.

IV.  ELIGIBILITY

The Committee establishes rules of eligibility for participation in the Plan and
determines eligibility in accordance with those rules.  For Fiscal Year 1998,
eligibility applies to all employees in Grades 18 and above, plus any Grade 16
and 17 directors.  Participation is effective as of the date approved by the
Committee and is communicated to the participant by an incentive opportunity
statement ("Participant Form") specifying the target incentive level for the
position.  No employee will become a participant in the Plan after May 1, 1998,
unless the employee is already a participant in the Management Incentive Plan
for Managers.

V.  PLAN GOALS

The Plan reinforces the key financial goals which support ADC's long-term
strategic plans.  The FY 1998 goal categories and weights for Business Unit
participants are as follows:

                 GOAL                                WEIGHT
                 ----                                ------
*       Business Unit EVA Improvement                 60%
        Business Unit Revenue                         20%
**      Key Business Unit Goal                        20%
                                                      ---

        TOTAL                                        100%

*    EVA Improvement is the dollar amount of planned year-over-year improvement
     in EVA.  EVA Improvement goals are set for each of the next 3 years.

**   The key Business Unit goal varies by Business Unit.  See attached goal  
     sheet for definition of applicable key Business Unit goal.

VI.  INCENTIVE PAYOUT OPPORTUNITIES

A.  The payout opportunity for meeting the Business Unit Revenue and key
Business Unit goal are as follows:

                                                  PAYOUTS
                                 -----------------------------------------
         GOAL                       THRESHOLD      TARGET       MAXIMUM
         ----                       ---------      ------       -------
         Business Unit Revenue     0% of Target     100%     400% of Target
         Key Business Unit Goal    0% of Target     100%     200% of Target

     Results between threshold-target and target-maximum are interpolated.

B.   The payout opportunity for meeting the EVA Improvement goal is as follows:

         GOAL                              THRESHOLD      TARGET       MAXIMUM
         ----                              ---------      ------       -------
         Business Unit EVA Improvement        N/A          100%          N/A 
                                          (unlimited                  (unlimited
                                           downside)                    upside)

     Incentive amounts are interpolated based on leverage (the slope of the
     line). 

     There are no thresholds and maximums for the EVA Improvement goal. 
     However, the specific incentive payout is a function of a bonus bank
     concept which is described in Section VII and Section VIII.

<PAGE>

VII.  BONUS BANK DEFINITION

As mentioned earlier, the Plan offers unlimited upside and downside rewards to
participants for creating value.  In order to ensure that EVA Improvements are
sustainable over a multi-year period, a bonus bank is created whereby
exceptional performance (above 200% of target) is credited to your account and
poor performance (negative amounts below 0% of the target level) is deducted
from your account.

The specific mechanics of the bonus bank are described below.

VIII.  HOW THE BONUS BANK WORKS

A.   A bonus bank account is created when the EVA Improvement goal achievement
     is above 200% of target or below 0% of the target level.

B.   Amounts achieved in excess of 200% of target are put into an EVA
     Improvement bonus bank.  These amounts vest at a rate of 25% per year,
     beginning immediately, and then after 1 year, 2 years, and 3 years,
     respectively.

C.   If EVA Improvement is less than 0% of the target level for the current Plan
     year, a negative amount is calculated and is handled as follows:

          1.  If there is a positive current year bonus bank amount, the
          negative amount offsets it.  After the negative has been applied, any
          positive vested amount is paid.  If the bonus bank is negative at the
          end of the year, the negative amount is carried over to the next 
          year.

          2.  If no positive bank balances have been carried forward from prior
          year(s), the entire negative amount goes into the bonus bank and is
          carried forward into the next plan year.  Then, in that next Plan
          year, if EVA Improvement is positive, the negative amount offsets
          amounts earned in that year in this manner and order:

               a)  Up to 100% of target achieved:  No reduction or offset. 
               Amount is paid immediately.

               b)  Between 100% and 200% of target.  Offset applies before any
               payout occurs.  The remaining amount, if any, is paid
               immediately.

               c)  Over 200% of target:  Offset applies before any amounts are
               banked and subject to vesting.   Any remaining amounts are
               subject to vesting schedule described above.

D.  The bonus bank is a bookkeeping account and as such, amounts allocated to a
    participant's bonus bank earn no interest, are unfunded, and do not
    actually vest until they are paid out in in accordance with the Plan.

<PAGE>

IX.  MAXIMUM EVA IMPROVEMENT GOAL PAYOUT IN ANY PLAN YEAR

Notwithstanding the above, the maximum amount that may be paid in any one year
to a participant due to the EVA Improvement goal, including amounts achieved for
the current year and bonus bank amounts that vest in the current year, may not
exceed 400% of the EVA Improvement target incentive amount.

X.  CURRENT PLAN YEAR PAYMENT

Payments which become due and payable under this Plan for the current Plan year
include:

- -    The amount achieved for the Revenue goal. 

- -    The amount achieved for the key Business Unit goal, PROVIDED THE THRESHOLD
     REVENUE DOLLAR AMOUNT IS MET OR 0% OF THE TARGET LEVEL FOR THE EVA
     IMPROVEMENT GOAL IS MET.

- -    Current year EVA Improvement goal achievement up to 200% of target (if
     there are no negative offsets).

- -    Vested amount of EVA Improvement bonus bank account balance.

Payments which become due and payable under this Plan are made as soon as
administratively feasible following the close of the Company's Fiscal Year.

XI.  CALCULATION OF INDIVIDUAL PAYMENTS AND BONUS BANK ACCOUNT  BALANCES

A.   The obligation to make payments under the Plan is determined by achievement
     of goals as determined by the Board of Directors.

B.  Calculations under this Plan are a function of:

          1.   Target incentive opportunity - expressed as a percentage of an
               individual's FY 1998 earnings.  The target % for each participant
               is designated on the "Participant Form."

          2.   Participant's 1998 Fiscal Year base salary earnings.

          3.   Performance against the established goals.

C.  Individual award calculations are shown by the following examples:

XII.  EFFECT OF CHANGE IN EMPLOYMENT STATUS 

A.  VOLUNTARY RESIGNATION AND RETIREMENT.  A participant who voluntarily resigns
full-time employment or retires prior to the end of the Fiscal Year receives no
payment under the Plan for the current Plan year's performance or any EVA bonus
bank account balances being carried over.  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year. 

B.  CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
involuntarily terminated or transferred to a position not eligible for this Plan
for reasons of unsatisfactory job performance receives no payment under the Plan
for the current Plan year's performance or any EVA bonus bank account balances
being carried over from prior Plan year(s).  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year.

C.  CHANGE BASED UPON JOB ELIMINATION. Subject to the approval of the Committee,
a participant who is involuntarily terminated or transferred to a position not
eligible for this Plan or another Management Incentive Plan because of a job
elimination may retain the right to a pro rata calculation under this Plan for
the current year's performance, plus a pro rata portion of any EVA bonus bank
balance that would otherwise have vested at the end of the current Plan year,
based upon the time served in the eligible position during the Fiscal Year,
provided at least three months was served in the eligible position.  Rights to
any unvested EVA bonus bank account balances at the end of the Plan year are
forfeited.  The participant does not have any obligations with respect to any
negative EVA bonus bank account balances that remain after the pro rata
calculation.  

D.  CHANGE BASED UPON PROMOTION, DEMOTION, OR TRANSFER TO ANOTHER ELIGIBLE PLAN
JOB.  A current participant who is promoted, demoted, or transferred from an
eligible position under this Plan to another eligible position under this Plan
during the Fiscal Year has a pro rata calculation of the current year's
performance awards based upon the time served in each position during the Fiscal
Year, provided at least three months were served in each position.  If a
participant is in an eligible position for less than three months during the
Fiscal Year, the payment calculation is based on the incentive level of the
position served in the longest.  Any positive or negative bonus bank accounts
transfer with the individual in their entirety.

E.  CHANGE IN JOBS WITHIN THE COMPANY BUT NOT ELIGIBLE FOR THIS PLAN.  A
participant who changes jobs within the Company but is not eligible for this
Plan, retains the right to a pro rata payout under this Plan for the current
year's performance, plus a pro rata portion of any EVA bonus balance that would
otherwise have vested at the end of the current Plan year, based upon the time
served in the eligible position during the Fiscal Year, provided at least three
months was served in the eligible position.  Rights to any unvested EVA bonus
bank account balances at the end of the Plan year are forfeited.  The
participant does not have any obligations with respect to any negative EVA bonus
bank account balances that remain after the pro rata calculation.
  
<PAGE>

F.  DEATH.  If a participant dies during the Fiscal Year, the participant's
heirs as determined by will or applicable laws of descent and distribution will
have a pro rata calculation of the current year's performance, plus a pro rata
portion of any EVA bonus bank balance that would otherwise have vested at the
end of the current Plan year, based upon the time served in the eligible
position during the Fiscal Year.  Rights to any unvested EVA bonus bank account
balances at the end of the current Plan year are forfeited.  The participant's
heirs do not have any obligations with respect to any negative EVA bonus bank
account balances that remain after the pro rata calculation.

XIII.  COMPLIANCE WITH SECTION 162(M) OF THE INTERNAL REVENUE CODE OF 1986

If a current Plan year payout causes the participant's total cash compensation
to exceed one  million dollars in the Fiscal Year, the participant must defer
the portion that exceeds the one million dollars in the ADC Telecommunications
Deferred Compensation Plan.

XIV.  AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

       GOAL                            THRESHOLD     TARGET      MAXIMUM
       ----                            ---------     ------      -------
       Corporate Revenue              0% of Target    100%    400% of Target
       Individual Contribution        0% of Target    100%    200% of Target

     Results between threshold-target and target-maximum are interpolated.

B.   The payout opportunity for meeting the EVA Improvement goal is as follows:

       GOAL                            THRESHOLD     TARGET      MAXIMUM
       ----                            ---------     ------      -------
       EVA Improvement                     N/A        100%          N/A
                                  (unlimited downside)     (unlimited upside)

     Incentive amounts are interpolated based on leverage (the slope of the
     line). 

     There are no thresholds and maximums for the EVA Improvement goal. 
     However, the specific incentive payout is a function of a bonus bank
     concept which is described in Section VII and Section VIII.

<PAGE>

VII.  BONUS BANK DEFINITION

As mentioned earlier, the Plan offers unlimited upside and downside rewards to
participants for creating value.  In order to ensure that EVA Improvements are
sustainable over a multi-year period, a bonus bank is created whereby
exceptional performance (above 200% of target) is credited to your account and
poor performance (negative amounts below 0% of the target level) is deducted
from your account.

The specific mechanics of the bonus bank are described below.

VIII.  HOW THE BONUS BANK WORKS

A.   A bonus bank account is created when the EVA Improvement goal achievement
     is above 200% of target or below 0% of the target level.

B.   Amounts achieved in excess of 200% of target are put into an EVA
     Improvement bonus bank.  These amounts vest at a rate of 25% per year,
     beginning immediately, and then after 1 year, 2 years, and 3 years,
     respectively.

C.   If EVA Improvement is less than 0% of the target level for the current Plan
     year, a negative amount is calculated and is handled as follows:

          1.   If there is a positive current year bonus bank amount, the
               negative amount offsets it.  After the negative has been applied,
               any positive vested amount is paid.  If the bonus bank is
               negative at the end of the year, the negative amount is carried
               over to the next year. 

          2.   If no positive bank balances have been carried forward from prior
               year(s), the entire negative amount goes into the bonus bank and
               is carried forward into the next plan year.  Then, in that next
               Plan year, if EVA Improvement is positive, the negative amount
               offsets amounts earned in that year in this manner and order:

                    a)  Up to 100% of target achieved:  No reduction or offset. 
                    Amount is paid immediately.

                    b)  Between 100% and 200% of target.  Offset applies before
                    any payout occurs.  The remaining amount, if any, is paid
                    immediately.

                    c)  Over 200% of target:  Offset applies before any amounts
                    are banked and subject to vesting.   Any remaining amounts
                    are subject to vesting schedule described above.

D.   The bonus bank is a bookkeeping account and as such, amounts allocated to a
     participant's bonus bank earn no interest, are unfunded, and do not
     actually vest until they are paid out in in accordance with the Plan.

<PAGE>

IX.  MAXIMUM EVA IMPROVEMENT GOAL PAYOUT IN ANY PLAN YEAR

Notwithstanding the above, the maximum amount that may be paid in any one year
to a participant due to the EVA Improvement goal, including amounts achieved for
the current year and bonus bank amounts that vest in the current year, may not
exceed 400% of the EVA Improvement target incentive amount.

X.  CURRENT PLAN YEAR PAYMENT

Payments which become due and payable under this Plan for the current Plan year
include:

- -    The amount achieved for the Revenue goal. 

- -    The amount achieved for the Individual Contribution goal, PROVIDED THE
     THRESHOLD REVENUE DOLLAR AMOUNT IS MET OR 0% OF THE TARGET LEVEL FOR THE
     EVA IMPROVEMENT GOAL IS MET.

- -    Current year EVA Improvement goal achievement up to 200% of target (if
     there are no negative offsets).

- -    Vested amount of EVA Improvement bonus bank account balance.

Payments which become due and payable under this Plan are made as soon as
administratively feasible following the close of the Company's Fiscal Year.

XI.  CALCULATION OF INDIVIDUAL PAYMENTS AND BONUS BANK ACCOUNT  BALANCES

A.   The obligation to make payments under the Plan is determined by achievement
     of goals as determined by the Board of Directors.

B.  Calculations under this Plan are a function of:

          1.   Target incentive opportunity - expressed as a percentage of an
               individual's FY 1998 earnings.  The target % for each participant
               is designated on the "Participant Form."

          2.   Participant's 1998 Fiscal Year base salary earnings.

          3.   Corporate and individual performance against the established
               goals.

C.  Individual award calculations are shown by the following examples:

XII.  EFFECT OF CHANGE IN EMPLOYMENT STATUS 

A.  VOLUNTARY RESIGNATION AND RETIREMENT.  A participant who voluntarily resigns
full-time employment or retires prior to the end of the Fiscal Year receives no
payment under the Plan for the current Plan year's performance or any EVA bonus
bank account balances being carried over.  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year. 

B.  CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
involuntarily terminated or transferred to a position not eligible for this Plan
for reasons of unsatisfactory job performance receives no payment under the Plan
for the current Plan year's performance or any EVA bonus bank account balances
being carried over from prior Plan year(s).  The participant does not have any
obligations with respect to any negative EVA bonus bank account balances
remaining at the end of the Plan year.

C.  CHANGE BASED UPON JOB ELIMINATION. Subject to the approval of the Committee,
a participant who is involuntarily terminated or transferred to a position not
eligible for this Plan or another Management Incentive Plan because of a job
elimination may retain the right to a pro rata calculation under this Plan for
the current year's performance, plus a pro rata portion of any EVA bonus bank
balance that would otherwise have vested at the end of the current Plan year,
based upon the time served in the eligible position during the Fiscal Year,
provided at least three months was served in the eligible position.  Rights to
any unvested EVA bonus bank account balances at the end of the Plan year are
forfeited.  The participant does not have any obligations with respect to any
negative EVA bonus bank account balances that remain after the pro rata
calculation.  

D.  CHANGE BASED UPON PROMOTION, DEMOTION, OR TRANSFER TO ANOTHER ELIGIBLE PLAN
JOB.  A current participant who is promoted, demoted, or transferred from an
eligible position under this Plan to another eligible position under this Plan
during the Fiscal Year has a pro rata calculation of the current year's
performance awards based upon the time served in each position during the Fiscal
Year, provided at least three months were served in each position.  If a
participant is in an eligible position for less than three months during the
Fiscal Year, the payment calculation is based on the incentive level of the
position served in the longest.  Any positive or negative bonus bank accounts
transfer with the individual in their entirety.

E.  CHANGE IN JOBS WITHIN THE COMPANY BUT NOT ELIGIBLE FOR THIS PLAN.  A
participant who changes jobs within the Company but is not eligible for this
Plan, retains the right to a pro rata payout under this Plan for the current
year's performance, plus a pro rata portion of any EVA bonus balance that would
otherwise have vested at the end of the current Plan year, based upon the time
served in the eligible position during the Fiscal Year, provided at least three
months was served in the eligible position.  Rights to any unvested EVA bonus
bank account balances at the end of the Plan year are forfeited.  The
participant does not have any obligations with respect to any negative EVA bonus
bank account balances that remain after the pro rata calculation.

<PAGE>

F.  DEATH.  If a participant dies during the Fiscal Year, the participant's
heirs as determined by will or applicable laws of descent and distribution will
have a pro rata calculation of the current year's performance, plus a pro rata
portion of any EVA bonus bank balance that would otherwise have vested at the
end of the current Plan year, based upon the time served in the eligible
position during the Fiscal Year.  Rights to any unvested EVA bonus bank account
balances at the end of the current Plan year are forfeited.  The participant's
heirs do not have any obligations with respect to any negative EVA bonus bank
account balances that remain after the pro rata calculation.

XIII.  COMPLIANCE WITH SECTION 162(M) OF THE INTERNAL REVENUE CODE OF 1986

If a current Plan year payout causes the participant's total cash compensation
to exceed one  million dollars in the Fiscal Year, the participant must defer
the portion that exceeds the one million dollars in the ADC Telecommunications
Deferred Compensation Plan.

XIV.  AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

<PAGE>

VI.   PLAN GOALS

The Plan reinforces the key financial goals which support ADC's long-term
strategic plans.  The FY 1998 goal categories and weights for International
participants are as follows:

            GOAL                               WEIGHT
            ----                               ------
      International Revenue                     60%

*     Corporate EVA Improvement                 20%

**    Individual Contribution                   20%
                                               ---
      TOTAL                                    100%

*     EVA Improvement is the dollar amount of planned year-over-year
      improvement in EVA.
      EVA Improvement goals are set for each of the next three years.

**    The Individual Contribution goal measures your performance against
      pre-determined objectives.  The objectives are to be documented on the
      attached "Individual Objective" form and require your direct manager's
      and Business Unit head's approval.

VII.  MINIMUM PERFORMANCE PAYOUT REQUIREMENTS

A.    To ensure protection of shareholder interest before an incentive payout
      can be generated, the threshold for International Revenue or Corporate
      EVA Improvement must be met.

VIII. CALCULATION OF PAYMENTS

A.    DETERMINATION OF ACHIEVEMENT AGAINST GOALS AND OBLIGATION TO MAKE
      PAYMENTS.

1.    The obligation to make payments under the Plan is determined by
      achievement of goals determined by the Board of Directors.

2.    The payout opportunity for meeting the goals are as follows:

            GOAL             THRESHOLD           TARGET          MAXIMUM
            ----             ---------           ------          -------
International Revenue       0% of Target          100%        400% of Target
Corporate EVA Improvement   0% of Target          100%        400% of Target
Individual Contribution     0% of Target          100%        200% of Target

Results between threshold-target and target-maximum are interpolated.

<PAGE>

B.    CALCULATION OF INDIVIDUAL PAYMENTS UNDER THIS PLAN IS A FUNCTION OF:

1.    Target incentive opportunity - expressed as a percentage of an
      individual's FY 1998 earnings.   The target % for each participant is
      designated on the "Participant Form."

2.    Participant's 1998 fiscal year base salary earnings.

3.    Performance against the established goals.

C.    INDIVIDUAL AWARD CALCULATIONS ARE SHOWN BY THE FOLLOWING EXAMPLE:

      Assume we have a Plan participant with the following facts:

      Grade:                            15
      Target Payout:                    11% of base salary earnings
      Base Salary Earnings:             65,000

      Minimum performance payout requirement is met.


      GOAL                                   WEIGHT         ACHIEVEMENT
                                                         (As a % of Target)

      International Revenue                   60%              100%

      Corporate EVA Improvement               20%              110%

      Individual Contribution                 20%              100%
                                                               ----

      OVERALL RESULT AS % OF TARGET                            102%

      Calculation of Payment:

      $65,000 (FY Earnings) x 11% (Target Opportunity) x 102% (Overall Result
      as a % of Target)=$7,293.
<PAGE>

IX.   EFFECT OF CHANGE IN EMPLOYMENT STATUS

A.    VOLUNTARY RESIGNATION.  A participant who voluntarily resigns full-time
      employment prior to the end of the Fiscal Year receives no payment under
      the Plan.

B.    CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
      involuntarily terminated or transferred to a non-eligible position for
      reasons of unsatisfactory job performance receives no payment under this
      plan.

C.    CHANGE BASED UPON JOB ELIMINATION. Subject to the approval of the
      Committee, a participant who is involuntarily terminated or transferred
      to a non-eligible position because of a job elimination may retain the
      right to a pro-rata payment based upon the time served in the eligible
      position during the fiscal year, provided at least three months was
      served in the eligible position.

D.    CHANGE BASED UPON PROMOTION / DEMOTION.  A current participant who is
      promoted or demoted from an incentive eligible position to another
      incentive eligible position during the fiscal year has a pro rata
      calculation of payment based upon the time served in each position during
      the Fiscal Year, provided at least three months was served in each
      position.  If a participant is in an eligible position for less than
      three months during the fiscal year, the payment calculation is based on
      the incentive level of the position served in the longest.

E.    CHANGE BASED UPON TRANSFER TO ANOTHER POSITION.  A current participant
      who transfers to another position within the Company that is eligible for
      participation in an ADC Management Incentive Plan with different goals
      during the Fiscal Year has a pro rata calculation of payment based on the
      goals and length of time served in the respective positions, provided at
      least three months was served in each position.  If a participant is in a
      job for less than three months during the Fiscal Year, the payment
      calculation is based on the goals of the position served in the longest.

F.    DEATH.  If a participant dies during the fiscal year, the participant's
      heirs as determined by will or applicable laws of descent and
      distribution has a pro-rata calculation of payment based upon the time
      the participant served in the eligible position during the fiscal year.

terminate this plan in whole or in part, at its sole discretion, and nothing in

                          (As Amended through April 1, 1997)

SECTION 1.   PURPOSE.

     This plan shall be known as the "ADC Telecommunications, Inc. Nonemployee
Director Stock Option Plan" and is hereinafter referred to as the "Plan." The
purpose of the Plan is to promote the interests of ADC Telecommunications, Inc.,
a Minnesota corporation (the "Company"), by enhancing its ability to attract and
retain the services of experienced and knowledgeable outside directors and by
providing additional incentive for such directors to increase their interest in
the Company's long-term success and progress.

SECTION 2.   ADMINISTRATION.

     The Plan shall be administered by a committee (the "Committee") of three or
more persons appointed by the Board of Directors of the Company.  Grants of
stock options under the Plan and the amount and nature of the awards to be
granted shall be automatic as described in Section 6. However, all questions of
interpretation of the Plan or of any options issued under it shall be determined
by the Committee and such determination shall be final and binding upon all
persons having an interest in the Plan.

SECTION 3.   PARTICIPATION IN THE PLAN.

     Each director of the Company shall be eligible to participate in the Plan
unless such director is an employee of the Company or any subsidiary of the
Company.

SECTION 4.   STOCK SUBJECT TO THE PLAN.

     Subject to the provisions of Section 11 hereof, the stock to be subject to
options under the Plan shall be authorized but unissued shares of the Company's
common stock, par value $.20 per share (the "Common Stock"). Subject to
adjustment as provided in Section 11 hereof, the maximum number of shares with
respect to which options may be exercised under this Plan shall be 840,000
shares. If an option under the Plan expires, or for any reason is terminated,
any shares that have not been purchased upon exercise of the option prior to the
expiration or termination date shall again be available for options thereafter
granted during the term of the Plan.

SECTION 5.   NONQUALIFIED STOCK OPTIONS.

     All options granted under the Plan shall be nonqualified stock options
which do not qualify as incentive stock options within the meaning of Section
422 of the Internal Revenue Code of 1986, as amended.

<PAGE>

SECTION 6.   TERMS AND CONDITIONS OF OPTIONS.

     Each option granted under this Plan shall be evidenced by a written
agreement in such form as the Committee shall from time to time approve, which
agreements shall comply with and be subject to the following terms and
conditions:

          (a)  INITIAL OPTION GRANTS.  An option to purchase 16,000 shares of
     Common Stock shall be granted automatically on the first business day
     immediately following each meeting of the Company's shareholders or Board
     of Directors during the term of the Plan to each eligible director, if any,
     who is elected to the Board of Directors for the first time at such
     meeting.

          (b)  ANNUAL OPTION GRANTS.  Subject to Section 6(c) hereof, an option
     to purchase 8,000 shares of Common Stock shall be granted automatically on
     the first business day immediately following each annual meeting of the
     Company's shareholders held during the term of the Plan beginning with the
     1995 annual meeting of shareholders (the "Annual Option Grant Date") to
     each eligible director in office on such Annual Option Grant Date who prior
     to such Annual Option Grant Date has received an option pursuant to
     Section 6(a) hereof.

          (c)  RETURN ON EQUITY REQUIREMENT.  No options shall be granted
     pursuant to Section 6(b) hereof on any Annual Option Grant Date if the
     Company's "return on equity" (as hereinafter defined) for the fiscal year
     ended immediately preceding such Annual Option Grant Date was less than
     10%.  "Return on equity" shall mean the percentage determined by dividing
     (i) the net income of the Company for such fiscal year by (ii) the total
     stockholders' investment in the Company as of the end of the next preceding
     fiscal year.  Net income and total stockholders' investment shall be
     determined by reference to the Company's audited financial statements.  If
     the Company does not have net income for any fiscal year, the return on
     equity for such fiscal year shall be deemed to be less than 10%.

          (d)  OPTIONS NON-TRANSFERABLE.  No option granted under the Plan shall
     be transferable by the optionee otherwise than by will or by the laws of
     descent and distribution as provided in Section 6(g) hereof; PROVIDED,
     HOWEVER, that an optionee may, in the manner established by the Committee,
     transfer an option to any member of such optionee's immediate family
     (which, for purposes of this clause (d) shall mean such optionee's
     children, grandchildren, or current spouse) or to one or more trusts
     established for the exclusive benefit of one or more such immediate family
     members or one or more partnerships in which the Participant or such
     immediate family members are the only partners, and PROVIDED FURTHER that
     (1) there is no consideration for such transfer, and (2) the options held
     by such transferees continue to be subject to the same terms and conditions
     (including restrictions on subsequent transfers) as were applicable to such
     options immediately prior to their transfer.  During the lifetime of the
     optionee, the


                                          2
<PAGE>

     options shall be exercisable only by such optionee.  No option or interest
     therein may be transferred, assigned, pledged or hypothecated by the
     optionee during such optionee's lifetime, except as set forth at this
     section (d), whether by operation of law or otherwise, or be made subject
     to execution, attachment or similar process.

          (e)  PERIOD OF OPTIONS.  Options shall terminate upon the expiration
     of 10 years from the date on which they were granted.

          (f)  EXERCISE OF OPTIONS.

               (i)    Options granted under the Plan shall not be exercisable
          for a period of one year after the date on which they were granted,
          but thereafter will be exercisable in full at any time or from time to
          time during the term of the option.
          
               (ii)   The exercise of any option granted hereunder shall only be
          effective at such time as counsel to the Company shall have determined
          that the issuance and delivery of Common Stock pursuant to such
          exercise will not violate any federal or state securities or other
          laws. An optionee desiring to exercise an option may be required by
          the Company, as a condition of the effectiveness of any exercise of an
          option granted hereunder, to agree in writing that all Common Stock to
          be acquired pursuant to such exercise shall be held for his or her own
          account without a view to any distribution thereof, that the
          certificates for such shares shall bear an appropriate legend to that
          effect and that such shares will not be transferred or disposed of
          except in compliance with applicable federal and state securities
          laws.

               (iii)  An optionee electing to exercise an option shall give
          written notice to the Company of such election and of the number of
          shares subject to such exercise. The full purchase price of such
          shares shall be tendered with such notice of exercise. Payment shall
          be made to the Company in cash (including check, bank draft or money
          order).

          (g)  EFFECT OF DEATH.  If the optionee shall die prior to the time the
     option is fully exercised, such option may be exercised at any time within
     two years after his or her death by the personal representatives or
     administrators of the optionee or by any person or persons to whom the
     option is transferred by will or the applicable laws of descent and
     distribution, to the extent of the full number of shares the optionee was
     entitled to purchase under the option on the date of death and subject to
     the condition that no option shall be exercisable after the expiration of
     the term of the option.

SECTION 6A.   ONE-TIME GRANT

Supplemental Retirement Plan prior to its termination, shall be converted to

                   3 to 4 years                      3,650
                   5 to 6 years                      5,450
                   6 to 7 years                      6,350
                    10 + years                       9,100

     Each such option shall have an exercise price equal to the market price of
a share of the Common Stock as of the close of trading on April 1, 1997, and
each such option shall be exercisable on the earlier of the date on which a
participant no longer is a member of the Board of Directors of the Company or
9.5 years from April 1, 1997, and each unexercised option shall expire ten years
from April 1, 1997.

SECTION 7.   OPTION EXERCISE PRICE.

     The option exercise price per share for the shares covered by each option
shall be equal to the "fair market value" of a share of Common Stock as of the
date on which the option is granted, as determined pursuant to Section 9 hereof.

SECTION 8.   TIME FOR GRANTING OPTIONS.

     Unless the Plan shall have been discontinued as provided in Section 13
hereof, the Plan shall terminate upon the expiration of 10 years from the date

the consent of the optionee, alter or impair any rights or obligations under any
option theretofore granted.

SECTION 9.   FAIR MARKET VALUE OF COMMON STOCK.

     For purposes of the Plan, the fair market value of the Common Stock on a
given date shall be (i) the last sale price of the Common Stock as reported on
the NASDAQ National Market System on such date, if the Common Stock is then
quoted on the NASDAQ National Market System, or (ii) the closing price of the
Common Stock on such date on a national securities exchange, if the Common Stock
is then being traded on a national securities exchange. If on the date as of
which the fair market value is being determined the Common Stock is not publicly
traded, the Committee shall make a good faith attempt to determine such fair
market value and, in connection therewith, shall take such actions and consider
such factors as it deems necessary or advisable.

SECTION 10.   LIMITATION OF RIGHTS.

     (a)  NO RIGHT TO CONTINUE AS A DIRECTOR.  Neither the Plan, nor the
granting of an option nor any other action taken pursuant to the Plan, shall
constitute, or be evidence of, any agreement or understanding, express or
implied, that the Company will retain a director for any period of time, or at
any particular rate of compensation.

     (b)  NO SHAREHOLDER RIGHTS FOR OPTIONS.  An optionee shall have no rights
as a shareholder with respect to the shares covered by options until the date of

will be made for cash dividends or other rights for which the record date is
prior to the date such certificate is issued.

SECTION 11.   ADJUSTMENTS TO COMMON STOCK.

     If there shall be any change in the Common Stock through merger,
consolidation, reorganization, recapitalization, stock dividend (of whatever
amount), stock split or other change in the corporate structure, appropriate
adjustments in the Plan and outstanding options shall be made. In the event of
any such changes, adjustments shall include, where appropriate, changes in the
aggregate number of shares subject to the Plan, the number of shares subject to
outstanding options and the option exercise prices thereof in order to prevent
dilution or enlargement of option rights.

SECTION 12.   EFFECTIVE DATE OF THE PLAN.

     The Plan shall take effect immediately upon its approval by the affirmative
vote of the holders of a majority of the shares present in person or by proxy
and voted at a duly held meeting of shareholders of the Company.

SECTION 13.   AMENDMENT OF THE PLAN.

     The Board may suspend or discontinue the Plan or revise or amend it in any
respect whatsoever; provided, however, that without approval of the shareholders
of the Company no revision or amendment shall be made that (a) absent such
shareholder approval, would cause Rule 16b-3, as promulgated by the Securities
and Exchange Commission under the Securities Exchange Act of 1934, as amended,
or any successor rule or regulation thereto, to become unavailable with respect
to the Plan or (b) requires the approval of the Company's shareholders under any
rules or regulations of the National Association of Securities Dealers, Inc. or
any securities exchange that are applicable to the Company.  The Board shall not
alter or impair any option theretofore granted under the Plan without the
consent of the holder of the option.

For purposes of determining the amount in the preceding schedule, pay shall mean
the sum of your base pay and your bonus received under an Incentive Bonus Plan
(MIP, SMIP or equivalent bonus), if any.

Your base pay shall be the greater of:

     (a)  your base pay in effect on the date of the Change in Control, or

     (b)  your base pay in effect on the date of the termination of your
          employment.

Your bonus shall be your Incentive Bonus under an Incentive Bonus Plan (MIP,

     (a)  the amount of such bonus earned as determined by your actual
          performance as of the date of the Change in Control, or if greater,
          the date of the termination of your employment, or

     (b)  the pro rata amount of such bonus targeted for the full Incentive
          Bonus plan year as determined by multiplying your full year target
          award by a fraction, the numerator of which is the number of months of
          service in such year as of the date of the termination of your
          employment and the


                                          2
<PAGE>

          denominator of which is twelve (12).  In determining the pro rata
          amount of such bonus, the Incentive Bonus plan year will be the plan
          year in which occurs the date of the Change in Control, or if it
          results in a greater pro rata amount, the Incentive Bonus plan year
          will be the Incentive Bonus plan year in which occurs the termination
          of your employment, or

          target award by a fraction, the numerator of which is the number of
          months of service in such quarter as of the date of the termination of
          your employment and the denominator of which is three (3).  In
          determining the pro rata amount of such bonus, the Incentive Bonus
          plan quarter will be the plan quarter in which occurs the date of the
          Change in Control, or if it results in a greater pro rata amount, the
          Incentive Bonus plan quarter will be the Incentive Bonus plan quarter
          in which occurs the termination of employment.

4.   BONUS PAYMENT.  Section 4.2 of the Plan Statement shall be amended to read
in full as follows:

                                     Section 4.2
                                  Amount of Payment

Subject to the eligibility requirement set forth in Section 4.1 and the

Bonus plan year for which your Incentive Bonus is being determined.  The amount
of such payment shall be the greater of:

     (a)  the amount of such bonus earned as determined by your actual
          performance as of the date of the Change in Control, or if greater,
          the date of the termination of your employment, or

     (b)  if bonuses are paid from the Incentive Bonus Plan annually, the pro
          rata amount of such bonus targeted for the full Incentive Bonus plan
          year as determined by multiplying your full year target award by a
          fraction, the numerator of which is the number of months of service in
          such year as of the date of the termination of your employment and the
          denominator of


                                          3
<PAGE>

          which is twelve (12).  In determining the pro rata amount of such
          bonus, the Incentive Bonus plan year will be the Incentive Bonus plan
          year in which occurs the date of the Change in Control, or if it
          results in a greater pro rata amount, the Incentive Bonus Plan year

          of your employment, or

     (c)  if bonuses are paid from the Incentive Bonus Plan monthly, the
          aggregate amount of such bonus payments paid during the Incentive
          Bonus plan year as of the date of the Change of Control, or if
          greater, the date of the termination of your employment, or

          aggregate amount of bonus payments paid during the Incentive Bonus
          plan year as of the date of the Change of Control: plus the pro rata
          amount of such bonus targeted for the full quarter of the Incentive
          Bonus plan quarter as determined by multiplying your full quarter
          target award by a fraction, the numerator of which is the number of
          months of service in such quarter as of the date of the termination of
          your employment and the denominator of which is three (3).  In
          determining the pro rata amount of such bonus, the (Incentive Bonus
          plan quarter will be the plan quarter in which occurs the date of the
          Change in Control, or if it results in a greater pro rata amount, the
          Incentive Bonus plan quarter will be the Incentive Bonus plan quarter
          in which occurs the termination of your employment.

                   PORTIONS OF 1997 ANNUAL REPORT TO SHAREHOLDERS


MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     The Company offers a broad range of products and services that enable its
customers to construct and upgrade their telecommunications networks to support
increasing user demand for voice, data and video services. The local loop is the
portion of the public network from the central office, through the equipment
that connects the local central office to the subscriber's equipment, onto the
customer premise and across the enterprise or residential network. Telephone
companies, cable television operators, wireless network providers and other
public network providers are building the infrastructure required to offer
Internet access, higher speed data, video and telephony services, entertainment
and other interactive services to residential and business customers. Greater
and greater amounts of network bandwidth are required for these services and the
Company's development efforts and product offerings are focused on "unlocking
the capacity of the local loop," eliminating bottlenecks and increasing the
speed and efficiency of the network. Such product offerings include equipment,
services and integrated solutions within the following general functional
product groups: transmission, enterprise networking and broadband connectivity.
The Company's transmission products are designed for use in copper based, coax
based, fiber based or wireless transmission networks and are sold primarily to
public network providers in the United States and internationally. The Company's
enterprise networking products are designed for use in copper based, fiber optic
and wireless networks and are sold primarily to private voice, data and video
network providers around the world. The Company's broadband connectivity
products are designed for use in copper based, coax, fiber optic or wireless
transmission networks and are sold to both public and private global network
providers.

     Historically, the Company's principal product offerings generally consisted
of copper based and fiber based products designed to address the needs of its
customers for transmission, enterprise networking and connectivity on
traditional telephony networks. With the growth of multimedia applications and
the associated development of enhanced voice, data and video services, the
Company's more recent product offerings and research and development efforts
have increasingly focused on emerging technologies and applications relating to
the broadband telecommunications equipment market. The market for broadband
telecommunications equipment is evolving and rapidly changing. The Company's
future growth is dependent in part on its ability to successfully develop and
commercially introduce new products in each of its product groups addressing
this


<PAGE>

market, as well as the growth in this market. The growth in the market for such
broadband telecommunications products is dependent on a number of factors,
including the amount of capital expenditures by public network providers,
regulatory and legal developments, any adjustments to overall market capital
expenditure rates which could result from the ongoing consolidation of customers
in this market as well as the influx of new customer entrants to the market and
end-user demand for integrated voice, data video and other network services.
There can be no assurance that the Company's new or enhanced products will meet
with market acceptance or be profitable.

     The Company's operating results may fluctuate significantly from quarter to
quarter due to several factors. The Company is growing through acquisition and
expansion and results of operations described in this report may not be
indicative of results to be achieved in future periods. The Company's expense
levels are based in part on expectations of future revenues. If revenue levels
in a particular period do not meet expectations, operating results will be
adversely affected. In addition, the Company's results of operations are subject
to seasonal factors. The Company historically has experienced a stronger demand
for its products in the fourth fiscal quarter, primarily as a result of customer
budget cycles and Company year-end incentives, and has experienced a weaker
demand for its products in the first fiscal quarter, primarily as a result of
the number of holidays during late November, December and early January and a
general industry slowdown during that period. There can be no assurance that
these historical seasonal trends will continue in the future.

</TABLE>


Net sales were $1.16 billion and $828.0 million for the years ended October 31,
1997 and 1996, reflecting 40.6% and 41.2% annual increases, respectively, over
the prior years. The increases in net sales in both 1997 and 1996 predominantly
reflect


                                         -3-
<PAGE>

increases in sales of transmission products (67.2% in 1997 and 65.3% in 1996)
and broadband connectivity products (32.5% in 1997 and 37.6% in 1996). Within
these two product groups, net sales increased approximately $109 million in 1997
and $70.0 million in 1996 as a result of revenue contributions from acquired
companies.

     In addition to the growth from acquisition, the Company's 67.2% and 65.3%
growth in net sales of transmission products during 1997 and 1996, respectively,
primarily reflects increased sales of transmission systems to public
telecommunications network providers such as telephone companies, cable TV
operators and wireless service providers. The very strong growth of transmission
product sales resulted in sales of transmission products increasing to 43.8% of
total net sales in 1997, from 36.8% of total net sales in 1996 and 31.5% of
total net sales in 1995. If the Company's transmission system products
internally developed or acquired within the last three years and continuing
enhancements to these products meet with reasonable market acceptance, the
Company anticipates that net sales of transmission products will continue to
grow as a percentage of the Company's total net sales.

     Besides the revenue growth from acquisitions, the Company's 32.5% and 37.6%
growth in net sales of broadband connectivity products in 1997 and 1996,
respectively, predominantly reflects the Company's success in selling these
products into new global broadband market applications (such as cable TV
companies and certain international customers). Within the broadband
connectivity product group, net sales of ADC's digital signaling cross-connect
(DSX) modules and bays have declined as a percentage of total net sales to 21.7%
from 22.7% in 1996 and 23.9% in 1995. The Company believes that future sales of
DSX and other copper connectivity products will continue to account for a
substantial portion of the Company's revenues, although these products may
continue to decline as a percentage of total net sales primarily due to changes
in the Company's product mix and the ongoing evolution of technologies in the
telecommunications marketplace.

     Net sales of enterprise networking products increased 6.0% and 14.3% during
1997 and 1996, respectively. These increases reflect growth in net sales of
public network access equipment, partially offset by decreases in net sales of
Local Area Network (LAN) equipment. Recognizing changes in the competitive
environment for LAN equipment and the industry trend toward integration of LAN
and Wide Area Network (WAN) technologies and products, the Company combined its
Kentrox and Fibermux subsidiaries into one enterprise networking group and
(during July 1997) transferred the Fibermux manufacturing operation to Kentrox.
This group combines LAN and WAN expertise in its development of advanced network
access and transport products.

     Net sales for 1997 and 1996 include $247.4 million and $172.2 million of
sales to customers outside of the U.S., representing 21.2% and 20.8%,
respectively, of total


                                         -4-
<PAGE>

net sales. If the Company's international marketing efforts continue to be
successful and if the Company's global products meet with reasonable market
acceptance, management anticipates that net sales outside the U.S. will continue
to grow as a percentage of the Company's total net sales.

     GROSS PROFIT  During 1997, 1996 and 1995, the gross profit percentages were
46.6%, 47.0% and 48.5% of net sales, respectively. The 1997 and 1996 declines in
gross profit percentages primarily resulted from the continuing change in
product sales mix toward sales of newer, lower margin products which address
emerging broadband applications. The Company anticipates that its future gross
profit percentages will continue to be affected by the mix of products the
Company sells, the timing of new product introductions and manufacturing volume,
among other factors.

     OPERATING EXPENSES  Total operating expenses for the years ended October
31, 1997, 1996 and 1995 were $377.0 million, $256.0 million and $203.8 million,
representing 32.4%, 30.9% and 34.8% of net sales, respectively. The increase in
operating expenses as a percentage of net sales during 1997 reflects the $22.7
million of non-recurring charges recorded during the quarter ended January 31,
1997. Such charges primarily represent the write-off of purchased research and
development resulting from the acquisition of the wireless infrastructure group
from PCSI, as well as expenses related to a consolidation of the Company's West
Coast operations. Operating expenses before non-recurring charges for 1997 were
$354.3 million, representing 30.4% of net sales. The 1997 decrease of .5% of net
sales (before non-recurring charges) compared to 1996 reflects the Company's
ability to leverage recurring operating expenses against revenue levels.

     The increases in absolute dollars of operating expenses during 1997 and
1996 were due primarily to expanded operations. In the year ended October 31,
1995, a non-recurring charge of $3.9 million related primarily to a personnel
reduction at the Fibermux facility resulting from the realignment of the
Company's enterprise networking operations. Operating expenses before this
charge for 1995 were $199.9, representing 34.1% of net sales. The 1996 decrease
of 3.2% of net sales compared to 1995 again reflects the Company's ability to
leverage operating expenses against revenue levels.

     Development and product engineering expenses were $122.6 million, $90.0
million and $66.5 million for the years ended October 31, 1997, 1996 and 1995,
respectively, reflecting increases of 36.2% during 1997 and 35.5% during 1996.
These increases resulted from substantial product development efforts in each of
the Company's three functional product groups and, in 1997 and 1996, newly
acquired businesses. The Company believes that, given the rapidly changing
technology and competitive environment in the telecommunications equipment
industry, continued commitment to product development efforts will be required
for the Company to remain competitive. Accordingly, the Company intends to
continue to


                                         -5-
<PAGE>

allocate substantial resources to product development for each of its three
functional product groups. However, the Company recognizes the need to balance
the cost of product development with expense control and remains committed to
carefully managing the rate of increase of such expenses.

     Selling and administration expenses were $221.6 million, $160.7 million and
$130.3 million for the years ended October 31, 1997, 1996 and 1995,
respectively, reflecting increases of 37.9% during 1997 and 23.3% during 1996.
These increases resulted from selling activities associated with new product
introductions, additional personnel costs related to expanded operations and, in
1997 and 1996, newly acquired businesses.

     Several of the Company's acquisitions have been accounted for as purchase
transactions in which the purchase prices exceeded the fair value of the
acquired assets. The amortization of these goodwill amounts over five to 25
years on a straight line basis resulted in increased goodwill amortization
expense for the years ended October 31, 1997 and 1996, to $10.0 million in 1997
and $5.2 million in 1996, from $3.1 million in the year ended October 31, 1995.
See Note 4 to the Consolidated Financial Statements included in this report for
a discussion of acquisitions made in 1997 and 1996.

     OTHER INCOME (Expense), Net  For the years ended October 31, 1997, 1996 and
1995, the net interest income category represented net interest income on cash
balances. See "Liquidity and Capital Resources" below for a discussion of cash
levels. Other expense for the years ended October 31, 1997 and 1996 primarily
represented the Company's share of net operating results of its venture
investments accounted for on an equity basis.

     INCOME TAXES  See Note 7 to the Consolidated Financial Statements included
in this report for a reconciliation of the federal statutory tax rate to an
effective tax rate of 36.0% in 1997, 1996 and 1995. This rate reflects the
varying amounts of non-deductible goodwill amortization included in operating
expenses in each of the three years, and the beneficial impact of tax credits.

     NET INCOME  Net income was $108.8 million (or $.83 per share) for the year
ended October 31, 1997, an increase of 24.4% over $87.5 million (or $.68 per
share) for the year ended October 31, 1996. The non-recurring charges of $22.7
million reduced net income by $.11 per share during 1997. Net income for 1996
represented an increase of 58.5% over $55.2 million (or $.47 per share) for the
year ended October 31, 1995.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents (primarily short-term investments in commercial
paper with maturities of less than 90 days) decreased $73.4 million and $55.3
million


                                         -6-
<PAGE>

during the years ended October 31, 1997 and 1996, respectively. The major
elements of the 1997 decrease were net income before non-recurring charges,
depreciation and amortization of $181.4 million offset by a $95.7 million
increase in working capital (reflecting the growth in the Company's business),
property and equipment additions of $119.0 million and acquisition payments of
$33.9 million. The higher level of property and equipment additions in 1997
reflects the continuation of certain major facilities and systems upgrades begun
in 1996. The major elements of the 1996 decrease were net income before
depreciation and amortization of $121.3 million offset by the $55.2 million
increase in working capital (reflecting the growth in the Company's business),
property and equipment additions of $69.1 million and acquisition payments of
$49.3 million. See Note 4 to the Consolidated Financial Statements included in
this report for a discussion of acquisitions.

     At October 31, 1997, the Company had approximately $3.8 million of debt
outstanding. All such debt represents debt of companies acquired during 1997 and
1996.

     Management believes that current cash balances and cash generated from
operating activities will be adequate to fund working capital requirements and
capital expenditures (for which approximately $35 million had been committed at
October 31, 1997) for 1998. However, the Company may find it necessary to seek
additional sources of financing to support its capital needs, for additional
working capital, potential investments or acquisitions, or otherwise.

QUARTERLY STOCK PRICE

     The Company's Common Stock, $.20 par value, is traded on the Nasdaq
National Market under the symbol "ADCT." The following table sets forth the high
and low sale prices for each quarter during the years ended October 31, 1997 and
1996, as reported on that system.  All prices have been restated to reflect a
two-for-one stock split effected in the form of a 100% stock dividend paid in
October 1996.

No cash dividends have been declared or paid during the past five years.  The
Company currently anticipates that it will retain any future earnings for use in
its business and does not anticipate paying any cash dividends in the
foreseeable future.  As of October 31, 1997, there were approximately 4,446
holders of record of the Common Stock.

Report of Independent Public Accountants



To ADC Telecommunications, Inc.:

     We have audited the accompanying consolidated balance sheets of ADC
TELECOMMUNICATIONS, INC. AND SUBSIDIARIES as of October 31, 1997 and 1996, and
the related consolidated statements of income, stockholders' investment and cash
flows for each of the three years in the period ended October 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ADC Telecommunications, Inc.
and Subsidiaries as of October 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
October 31, 1997, in conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION  The consolidated financial statements include the
accounts of ADC Telecommunications, Inc. (a Minnesota corporation) and all
significant subsidiaries in which ADC has more than a 50% equity ownership
(collectively, the "Company"). All significant intercompany transactions and
balances have been eliminated in consolidation.

CASH EQUIVALENTS  Cash equivalents primarily represent short-term investments in
commercial paper with original maturities of three months or less. The carrying
amounts of these investments approximate their fair value due to their short
maturities.

INVENTORIES  Inventories include material, labor and overhead and are stated at
the lower of first-in, first-out cost or market.

PROPERTY AND EQUIPMENT  Property and equipment are recorded at cost and
depreciated using the straight-line method over estimated useful lives of three
to thirty years or, in the case of leasehold improvements, over the term of the
lease, if shorter. Both straight-line and accelerated methods of depreciation
are used for income tax purposes.

GOODWILL  The excess of the cost of acquired businesses over the fair value of
the net assets acquired is amortized on a straight-line basis ranging from five
to twenty-five years. Management periodically assesses the amortization period
and recoverability of the carrying amount of goodwill based upon an estimate of
future cash flows from related operations.

RESEARCH AND DEVELOPMENT COSTS  The Company's policy is to expense all research
and development costs in the period incurred.

INCOME TAXES  The Company utilizes the liability method of accounting for income
taxes. Deferred tax liabilities or assets are recognized for the expected future
tax consequences of temporary differences between the book and tax bases of
assets and liabilities.

EARNINGS PER SHARE  Earnings per share is computed using the weighted average
number of common shares outstanding during the year, after consideration of the
dilutive effect of stock options and restricted stock awards.


                                         -15-
<PAGE>

FOREIGN CURRENCY TRANSLATION  The Company accounts for translation of foreign
currency in accordance with the provisions of SFAS No. 52. The resulting
translation adjustments are recorded directly to a separate component of
stockholders' investment. Use of Estimates  The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the amounts reported in
the financial statements and accompanying notes. Although these estimates are
based on management's knowledge of current events and actions it may undertake
in the future, they may ultimately differ from actual results.

NEW ACCOUNTING PRONOUNCEMENTS  SFAS No. 128 - Earnings Per Share was issued
during February 1997 and simplifies the standards for calculating and presenting
earnings per share. This pronouncement is effective for periods ending after
December 15, 1997; earlier application is not permitted. The adoption of SFAS
No. 128 will not have a material impact on the calculation of earnings per share
given the Company's present capital structure.

NON-RECURRING CHARGES  During the first quarter of 1997, the Company recorded a
non-recurring charge of $22.7 million. This charge primarily represented the
write-off of purchased research and development from the acquisition of the
Wireless Infrastructure Group of Pacific Communications Sciences, Inc. ("PCSI"),
as well as expenses related to the consolidation of the Company's West Coast
operations.

     During the second quarter of 1995, the Company initiated a realignment of
its Kentrox and Fibermux subsidiaries into one business unit. The Company
recorded a charge of $3,914,000 in conjunction with the realignment, related
primarily to a personnel reduction. As a result of the realignment,
approximately 100 Fibermux employees, primarily in sales, administration and
engineering, were separated from the Company.

NOTE 4: ACQUISITIONS

     During the first quarter of 1997, the Company acquired substantially all
the assets and liabilities of the Wireless Infrastructure Group of PCSI, a
wholly-owned subsidiary of Cirrus Logic, Inc., for $23 million in cash. The
Wireless Infrastructure Group designs and manufactures equipment for wireless
data and advanced paging communications. The acquisition was accounted for as a
purchase, and resulted in a non-recurring charge for the write-off of purchased
research and development described in Note 2. The inclusion of the Wireless
Infrastructure Group operating results for periods prior to the date of
acquisition would not have materially affected results of operations.

     During 1997, the Company exchanged a total of 2,239,356 shares of its
common stock in two separate business combinations for all of the outstanding
common stock of The Apex Group, Inc. ("Apex") and NewNet, Inc. ("NewNet"). Both
transactions were accounted for as poolings of interests. Apex, acquired during
April, provides information management and consulting services. NewNet, acquired
during October, develops intelligent network telecommunications software. During
1996, the Company exchanged a total of 1,910,965 shares of its common stock in
three separate business combinations for all the outstanding shares of Da Tel
Fibernet, Inc. ("Da Tel"), Information Transmission Systems Corp. ("ITS"), and
Metrica Systems Limited ("Metrica"). These transactions were accounted for as
poolings of interests. Da Tel was acquired during March and provides
engineering, design and installation services for telecommunications companies.
ITS also was acquired during March and designs and manufactures wireless
television transmission products for the cable and broadcast industries.
Metrica, a United Kingdom based company, was acquired during May and designs and
manufactures management software for wireless networks.

     Financial data for periods prior to the closing of these five pooling
transactions have not been restated because neither the net assets nor operating
results were material, individually or in the aggregate, to the Company's
consolidated financial statements.

     During the second quarter of 1996, the Company purchased all of the
outstanding stock of Skyline Technology, Inc. ("Skyline") for an initial cash
payment of $12 million and additional consideration not to exceed $20 million.
The purchase price exceeded the fair value of the acquired assets by
approximately $11 million. Additional consideration may be payable over a three
year period beginning November 1, 1996, subject to the achievement of certain
financial results. No additional consideration was earned during 1997. Skyline
designs and manufactures ISDN/Frame Relay access products.


                                         -19-
<PAGE>

     During the third quarter of 1996, the Company purchased 80% of the
outstanding common stock of Solitra Oy ("Solitra"), based in Kempele, Finland,
and agreed to acquire the remaining 20% over a three-year period. The stock was
acquired for an initial cash payment of $41 million plus additional
consideration which is payable subject to the achievement of certain financial
results. The initial purchase price exceeded the fair value of the acquired
assets by approximately $38.5 million. Additional consideration, if any, will be
payable over a three-year period beginning November 1, 1996. During 1997,
approximately $3 million of additional consideration was earned and will be
payable during 1998. Solitra designs and manufactures components for cellular
network base stations as well as high specification filters for mobile phones.

     The acquisitions of Skyline and Solitra were accounted for as purchases.
Accordingly, the results of operations of the acquired entities have been
included in the Company's consolidated financial statements since the respective
dates of acquisition. Goodwill associated with these acquisitions is being
amortized using the straight line method over periods ranging from ten to
fifteen years. The inclusion of Skyline and Solitra financial data prior to the
dates of acquisition would not have materially affected reported results.

     The rate of compensation increase used to measure the projected benefit
obligation was 5% for all three years. The expected long-term rate of return on
plan assets was 9%.

     During 1997, the Board approved the termination of the defined benefit
plan. The termination of the defined benefit plan will be effective January 5,
1998, with the actual settlement of the plan scheduled for 1998. The effect of
the termination and subsequent settlement are not material to the Company's
operations. The following table sets forth the funded status of the plan as of
October 31:

RETIREMENT SAVINGS PLAN  The Company maintains a Retirement Savings Plan for
employees who have completed one year of service. The Company contributes 1% of
wages and, depending on Company performance, partially matches employee
contributions to the Plan up to 6% of wages. Employees are fully vested in all
contributions. The Company's contributions to the plan totaled $8,232,000,
$7,394,000


                                         -21-
<PAGE>

and $6,141,000 during 1997, 1996, and 1995, respectively. A portion of the
Company's cash contributions is invested in the Company's stock by the Plan's
trustee.

STOCK AWARD PLANS  The Company maintains a Stock Incentive Plan to grant certain
stock awards, including stock options at fair market value and restricted
shares, to key employees of the Company. A maximum of 22,419,008 stock awards
can be granted under this plan; 8,711,011 shares were available for stock awards
as of October 31, 1997. The Company also maintains a Nonemployee Director Stock
Option Plan in order to enhance the ability to attract and retain the services
of experienced and knowledgeable outside directors. This plan provides for
granting of a maximum of 840,000 non-qualified stock options at fair market
value.  As of October 31, 1997, 384,500 shares were available for option grants
under this plan. In addition, a total of 427,422 shares have been reserved under
plans adopted in conjunction with certain acquisitions.

The following schedule summarizes activity in the plans:

     During 1995, options for 1,273,476 shares were exercised at prices ranging
from $1 to $13 per share.

     During 1997, the Company adopted SFAS No. 123 "Accounting for Stock-Based
Compensation" which encourages, but does not require, a fair value based method
of accounting for employee stock options or similar equity instruments. As
permitted under the new standard, the Company has continued to account for
employee stock options using the intrinsic value method outlined in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees."
Accordingly, no compensation expense has been recognized by the company for its
Stock Incentive Plan or its Non-employee Director Stock Option Plan. If
compensation expense for the Company's stock-based compensation plans had been
determined based on the fair value at the grant dates consistent with the


                                         -22-

method of SFAS No. 123, the Company's net income and earnings per share would
have decreased to the pro forma amounts indicated below:

     Pro forma net income reflects only options and other stock based awards
granted during 1997 and 1996. Therefore, the full impact of calculating
compensation costs for stock options under SFAS No. 123 is not reflected in the
pro forma net income amounts presented because compensation cost is reflected
over the options' vesting period, which is normally three years, and
compensation cost for options granted prior to fiscal year 1996 is not
considered.

     The weighted-average fair value per option at the date of grant for options
granted in 1997 and 1996 was $17.34 and $11.24, respectively. The fair value was
estimated using the Black-Scholes option pricing model with the following
weighted average assumptions for 1997 and 1996:

                                                        1997           1996

NOTE 6: CAPITAL STOCK

AUTHORIZED STOCK  The Company is authorized to issue 300,000,000 shares of $0.20
par value common stock and 10,000,000 shares of no par value preferred stock.
There are no preferred shares issued.

STOCK SPLIT  On September 24, 1996, the Company declared a two-for-one stock
split effected in the form of a 100% stock dividend paid November 1, 1996. All
references in the accompanying financial statements and notes to earnings per
share, average common shares outstanding, Stock Award Plan data and related
share prices have been adjusted to reflect the split.

STOCK OFFERING  On June 14, 1995, the Company completed a secondary public
offering of 6,325,000 shares of its common stock at $30 per share. The net
proceeds from the offering were $181,754,000, which are used for general
corporate purposes,


                                         -23-

including working capital, capital expenditures and possible acquisitions or
strategic alliances.

SHAREHOLDER RIGHTS PLAN  The Company has adopted a Shareholder Rights Plan which
provides that if any person or group acquires 15% or more of the Company's
common stock, each right not owned by such person or group will entitle its
holder to purchase, at the Right's then current purchase price ($62.50 for each
one-half share of the Company's common stock at October 31, 1997) common stock
of the Company having a value of twice the Right's purchase price. The Rights
would not be triggered, however, if the acquisition of 15% or more of the
Company's common stock is pursuant to a tender offer or exchange for all
outstanding shares of the Company's common stock which is determined by the
board of directors to be fair and in the best interests of the Company and its
stockholders. The Rights are redeemable at $0.01 per share any time prior to the
time they become exercisable. The Rights will expire on November 28, 2005, if
not previously redeemed or exercised.

     The Company desires to take advantage of the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995 and is filing this
cautionary statement in connection with such safe harbor legislation.  This Form
10-K, the Company's Annual Report to Shareholders, any Form 10-Q or Form 8-K of
the Company or any other written or oral statements made by or on behalf of the
Company may include forward-looking statements which reflect the Company's
current views with respect to future events and financial performance.  The
words "believe," "expect," "anticipate," "intends," "estimate," "forecast,"
"project" and similar expressions identify forward-looking statements.

     The Company wishes to caution investors that any forward-looking statements
made by or on behalf of the Company are subject to uncertainties and other
factors that could cause actual results to differ materially from such
statements.  These uncertainties and other factors include, but are not limited
to the Risk Factors listed below (many of which have been discussed in prior SEC
filings by the Company).  Though the Company has attempted to list
comprehensively these important factors, the Company wishes to caution investors
that other factors may in the future prove to be important in affecting the
Company's results of operations.  New factors emerge from time to time and it is
not possible for management to predict all of such factors, nor can it assess
the impact of each such factor on the business or the extent to which any
factor, or combination of factors, may cause actual results to differ materially
from those contained in any forward-looking statements.

     Investors are further cautioned not to place undue reliance on such
forward-looking statements as they speak only of the Company's views as of the
date the statement was made.  The Company undertakes no obligation to publicly
update or revise any forward-looking statements, whether as a result of new
information, future events or otherwise.

                                    RISK FACTORS

     RAPID TECHNOLOGICAL CHANGE AND IMPORTANCE OF NEW PRODUCTS.  The
telecommunications equipment industry is characterized by rapid technological
change, evolving industry standards, changing market conditions and frequent new
product introductions and enhancements.  The introduction of products embodying
new technologies or the emergence of new industry standards can render existing
products or products under development obsolete or unmarketable.  ADC's ability
to anticipate changes in technology and industry standards and successfully to
develop and introduce new products on a timely basis will be a significant
factor in ADC's ability to grow and remain competitive.  New product development
often requires long-term forecasting of market trends, development and
implementation of new technologies and processes and a substantial capital
commitment.  ADC has invested and continues to invest substantial resources
toward the development of new products.  Development and customer acceptance of
new products is inherently uncertain, and there can be no assurance that ADC
will successfully complete the commercialization of new products on a timely
basis or that such products will be commercially successful.  Any failure by ADC
to anticipate or respond on a cost-effective and timely basis to technological
developments, changes in industry standards or customer requirements, or any
significant delays in product development or introduction, could have a material
adverse effect on ADC's business, operating results and financial condition.

     UNCERTAIN MARKET FOR BROADBAND NETWORK PRODUCTS.  Over the past several
years, ADC's principal product offerings have generally consisted of
copper-based and fiber-based products designed to address the needs of its
customers for connectivity, transmission and networking applications on
traditional telephony networks.  However, with the growth of multimedia and the
associated development of enhanced voice, video and data transmission
technologies, ADC's recent product offerings and research and development
efforts have been increasingly focused on addressing the broadband
telecommunications equipment market through the use of new or different
technologies.  The market for broadband


                                          1
<PAGE>

telecommunications products is emerging and rapidly changing.  ADC's future
growth is dependent in part on its ability to successfully develop and
commercially introduce new products in each of its product groups addressing
this market, as well as the growth in this market.  The growth in the market for
such broadband telecommunications products is dependent on a number of factors,
including regulatory and legal developments and end-user demand for integrated
voice, video, data and other network services.  There can be no assurance that
the market for broadband telecommunications products will develop rapidly, or
that there can be reliable predictions made of technological trends or products
in this field.  In addition, to the extent this market develops, there can be no
assurance that ADC's products will meet with market acceptance or be profitable.
There also can be no assurance that public network providers will increase or
maintain consistent levels of capital expenditures for deployment of
telecommunications network systems, equipment or technologies, or that they will
respond quickly or favorably to regulatory changes in the telecommunications
equipment industry.

     COMPETITION.  Competition in the telecommunications equipment industry is
intense, and ADC believes that competition may increase substantially with the
deployment of broadband networks and the recent regulatory changes.  See
"Changing Regulatory Environment."  Many of ADC's foreign and domestic
competitors have more extensive engineering, manufacturing, marketing, financial
and personnel resources than ADC.  ADC believes its success in competing with
other manufacturers of telecommunications products depends primarily on its
engineering, manufacturing and marketing skills, the price, quality and
reliability of its products, and its delivery and service capabilities.  ADC
anticipates increasing pricing pressures from current and future competitors in
certain of the markets for its products.  In addition, ADC believes that
technological change, the increasing addition of data, video and other services
to networks, continuing regulatory change and industry consolidation or new
entrants will continue to cause rapid evolution in the competitive environment
of the telecommunications equipment market, the full scope and nature of which
is difficult to predict at this time.  Increased competition could result in
price reductions, reduced margins and loss of market share by ADC.  There can be
no assurance that ADC will be able to compete successfully with its existing or
new competitors or that competitive pressures faced by ADC will not materially
and adversely affect its business, operating results and financial condition.

     FLUCTUATIONS IN OPERATING RESULTS.  ADC's operating results may 
fluctuate significantly from quarter to quarter due to several factors, 
including, without limitation, the volume and timing of orders from, and 
shipments to, major customers, the timing of and the ability to obtain new 
customer contracts, the timing of new product announcements and the 
availability of product by ADC or its competitors, overall level of capital 
expenditures by public network providers, market acceptance of new and 
enhanced versions of ADC's products, variations in the mix of products ADC 
sells or its sales channels, and the availability and cost of key components. 
Many of the foregoing factors, in turn, are affected by the changing 
competitive environment in which the Company's customers operate and may be 
affected by consolidation among telecommunications service providers. In 
addition, the Company is experiencing growth through acquisition and 
expansion, and its recent results of operations may not be indicative of 
results to be achieved in future periods. ADC's expense levels are based in 
part on expectations of future revenues.  If revenue levels in a particular 
period do not meet expectations, operating results will be adversely 
affected. In addition, ADC's results of operations are subject to seasonal 
factors.  ADC historically has experienced a stronger demand for its products 
in the fourth fiscal quarter, primarily as a result of ADC year-end 
incentives and customer budget cycles, and has experienced a weaker demand 
for its products in the first fiscal quarter, primarily as a result of the 
number of holidays in late November, December and early January and a general 
industry slowdown during that period.  There can be no assurance that these 
historical seasonal trends will continue in the future.

     CHANGING REGULATORY ENVIRONMENT.  The telecommunications industry is
subject to regulation in the United States and other countries.  ADC's business
is dependent upon the continued growth of the telecommunications industry in the
United States and internationally.  Federal and state regulatory agencies
regulate most of ADC's domestic customers.  On January 3, 1996, the U.S.
Congress passed the Telecommunications Act of 1996 (the "Telecommunications
Act").  The President of the United States signed the Telecommunications Act
into law on February 8, 1996.  The Telecommunications Act will lift certain
restrictions on the ability of companies, including Regional Bell Operating
Companies ("RBOCs") and other customers of ADC, to compete with one another and
change the regulation of the telecommunications industry.  While ADC believes
that the changes in regulation of the


                                          2
<PAGE>

telecommunications industry could increase ADC's opportunities to provide
solutions for its customers' voice, data and video needs, this is dependent on
the reaction of ADC's existing and prospective customers to such regulatory
trends.  To date, increased competition among telecommunications service
providers as contemplated by the Telecommunications Act has not been fully
realized and there can be no assurance as to the timing and intensity of such
competition.  The effect on the market for ADC's products also is difficult to
predict at this time, and there can be no assurance that competition in ADC's
product market will not intensify as a result of such changes in regulation.
Changes in current or future laws or regulations, in the United States or
elsewhere, could materially and adversely affect ADC's business.

     INTERNATIONAL OPERATIONS.  Export sales accounted for 18%, 21% and 21% of
ADC's net sales in fiscal 1995, 1996, and 1997, respectively, and ADC expects
that export sales may increase as a percentage of net sales in the future.  In
addition, ADC owns or subcontracts manufacturing operations located in Mexico,
Australia, China, Finland, and the United Kingdom.  Due to its export sales and
its international manufacturing operations, ADC is subject to the risks of
conducting business internationally, including unexpected changes in, or
impositions of, legislative or regulatory requirements, fluctuations in the U.S.
dollar which could materially and adversely affect U.S. dollar revenues or
operating expenses, tariffs and other barriers and restrictions, potentially
longer payment cycles, greater difficulty in accounts receivable collection,
potentially adverse taxes, and the burdens of complying with a variety of
foreign laws and telecommunications standards.  ADC also is subject to general
geopolitical risks, such as political and economic instability and changes in
diplomatic and trade relationships, in connection with its international
operations.  ADC maintains business operations throughout Asia, and has business
arrangements in Korea, Indonesia and Malaysia.  Economic conditions in these
countries, and in Asia in general, which first came to light in November 1997,
represent a potential risk to these business arrangements.  There can be no
assurance that the Company's business arrangements in Asia will not suffer
adverse impact from these conditions.  There also can be no assurance that such
factors will not materially and adversely affect ADC's operations in the future
or require ADC to modify significantly its current business practices.  In
addition, the laws of certain foreign countries may not protect ADC's
proprietary technology to the same extent as do the laws of the United States.

     DEPENDENCE ON PROPRIETARY TECHNOLOGY.  ADC's future success depends in part
upon its proprietary technology.  Although ADC attempts to protect its
proprietary technology through patents, copyrights and trade secrets, it also
believes that its future success will depend upon product development,
technological expertise and distribution channels.  There can be no assurance
that ADC will be able to protect its technology, or that competitors will not be
able to develop similar technology independently.  ADC has received and may in
the future receive from third parties, including some of its competitors,
notices claiming that it is infringing third-party patents or other proprietary
rights. There can be no assurance that ADC would prevail in any litigation over
third-party claims, or that it would be able to license any valid and infringed
patents on commercially reasonable terms.  Furthermore, litigation, regardless
of its outcome, could result in substantial cost to and diversion of effort by
ADC.  Any litigation or successful infringement claims by third parties could
materially and adversely affect ADC's business, operating results and financial
condition.

     VOLATILITY OF STOCK PRICE.  Based on the trading history of its stock, ADC
believes factors such as announcements of new products by ADC or its
competitors, quarterly fluctuations in ADC's financial results, customer
contract awards, developments in telecommunications regulation and general
conditions in the telecommunications equipment industry have caused and are
likely to continue to cause the market price of ADC's Common Stock to fluctuate
substantially.  In addition, telecommunications equipment company stocks have
experienced significant price and volume fluctuations that often have been
unrelated to the operating performance of such companies. This market volatility
may adversely affect the market price of ADC's Common Stock.
