Common Stock on a share-for-share basis. See "Principal and Selling
Stockholders" and "Description of Capital Stock."
 
     The Class A Common Stock is quoted on the Nasdaq National Market under the
symbol "WSTL." On May 30, 1996, the last reported sale price of the Class A
Common Stock on the Nasdaq National Market, after giving effect to the stock
split described below, was $38 1/8 per share. See "Price Range of Class A Common
Stock."
 
     The Company's Board of Directors recently declared a two-for-one stock
split in the form of a 100 percent stock dividend to be paid on June 7, 1996 to
holders of record on May 20, 1996 (the "Stock Split"). All share and per share
data in this Prospectus have been adjusted to reflect the Stock Split.

                               PROSPECTUS SUMMARY
 
     The following summary should be read in conjunction with, and is qualified
in its entirety by, the more detailed information, including "Risk Factors" and
the Consolidated Financial Statements and Notes thereto, appearing elsewhere in
this Prospectus. As used in this Prospectus, the terms "Westell" and "Company"
include Westell Technologies, Inc. and its subsidiaries, unless the context
otherwise indicates. The discussion in this Prospectus contains forward-looking
statements which include risks and uncertainties. The Company's actual results
could differ materially from those discussed in this Prospectus. Factors that
could cause or contribute to such differences include those discussed in the
sections entitled "Risk Factors," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business," as well as those
discussed elsewhere in this Prospectus.
 
                                  THE COMPANY
 
     Since 1980, Westell Technologies, Inc. ("Westell" or the "Company") has
developed telecommunications products that address the needs of telephone
companies ("telcos") to upgrade their existing network infrastructures
continually in order to deliver advanced data and voice services to their
customers. The Company designs, manufactures, markets and services a broad range
of digital and analog products used by telcos to deliver services primarily over
existing copper telephone wires that connect end users to a telco's central
office (the "local access network"). The Company also markets its products and
services to other telecommunications and information service providers seeking
direct access to end-user customers. The Company's principal customers include
all seven Regional Bell Operating Companies (the "RBOCs") as well as GTE,
British Telecom and Telecom Italia. In addition, Westell sells products to
several other entities, including public telephone administrations located
outside the U.S., independent domestic local exchange carriers, competitive
access providers, interexchange carriers and the U.S. federal government.
 
     Westell is a leading developer and provider of broadband telecommunications
access systems using an emerging technology known as Asymmetric Digital
Subscriber Line ("ADSL"). ADSL systems will allow telcos to provide interactive
multimedia services over existing copper wire, thus offering a more
cost-effective and faster deployment alternative to fiber optic cable in the
"last mile" of the local access network. ADSL systems enable interactive
multimedia services such as advanced data dialtone applications, including high
speed Internet access, local area network ("LAN") extension, telecommuting and
medical imaging, as well as emerging video dialtone applications, including
video-on-demand, distance learning, video conferencing and work at home.
Currently, over 30 domestic and international telcos, including Bell Atlantic,
GTE, US West !nterprise, British Telecom and Telecom Italia, are conducting
technical or marketing trials for new interactive multimedia services that rely
on the Company's ADSL systems.
 
     The Company's objective is to be a global leader in providing low cost and
high quality local access network products that enable telcos to meet the
growing demand for service offerings based on digital technology. Westell's
strategy is to leverage its leadership position in the ADSL market to capture
emerging opportunities as telcos expand their interactive multimedia offerings.
With over 15 years of experience in developing products for the local access
network, particularly T-1 Network Interface Units ("NIUs"), the Company also
intends to capitalize upon its existing customer relationships to continue to
develop cost-effective and implementable intelligent network products and access
systems. The Company believes that its pursuit of strategic relationships with
technology leaders enables it to obtain the emerging technologies required in
its product development efforts and to focus on specific product applications
for its telco customers.

rules promulgated pursuant to the Securities Act of 1933, as amended (the
"Securities Act")). Because such forward-looking statements include risks and
uncertainties, actual results may differ materially from those expressed in or
implied by such forward-looking statements. Factors that could cause actual
results to differ materially include, but are not limited to, those discussed
herein under "Risk Factors." The Company undertakes no obligation to release
publicly the result of any revisions to these forward-looking statements that

reflect the occurrence of unanticipated events.
 
                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered in evaluating the Company and its business before
purchasing shares of the Class A Common Stock offered hereby.
 
RELIANCE ON EMERGING MARKET FOR ADSL TECHNOLOGY; ANTICIPATED LOSSES
 
     The Company's future growth is substantially dependent upon whether DSL
technology, particularly as it relates to ADSL systems, gains widespread
commercial acceptance by telcos. Since 1992, the Company has invested, and
expects to continue to invest, significant resources in the development of ADSL
technology. However, the market for products using ADSL technology is only now
emerging as telcos have recently begun to consider implementing ADSL technology
in their networks. As a result, revenues from ADSL systems have been difficult
for the Company to forecast, and the Company's overall results of operations
have experienced substantial fluctuations in recent periods. The timing of
orders and shipments of ADSL systems can have a significant impact on the
Company's revenues and results of operations. For example, the Company's
revenues increased by $9.8 million in the fourth quarter of fiscal 1995 compared
to the third quarter of fiscal 1995 due to a large shipment of ADSL systems to
one customer. The Company has continued to ship ADSL systems but at a reduced
level from that of the fourth quarter of fiscal 1995, which has resulted in a
reduction in quarterly revenues when compared to the preceding quarter in three
of the four quarters in fiscal 1996. Due to the Company's significant ongoing
investment in ADSL technology, the Company anticipates losses in at least the
first and second quarters of fiscal 1997. The Company's ability to achieve
profitability or revenue growth in the future will depend upon market acceptance
of the Company's ADSL systems and the development and market acceptance of other
DSL products introduced by the Company. To date, telcos have deployed the
Company's ADSL systems solely for technical and marketing trials and have not
yet begun commercial deployment. The Company is unable to predict whether such
technical and marketing trials will be successful and when commercial deployment
will begin, if at all. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
     The RBOCs and the Company's other customers are significantly larger than,
and are able to exert a high degree of influence over, the Company. Prior to
selling its products to telcos, the Company must undergo lengthy approval and
purchase processes. Evaluation can take a year or more for complex products
based on new technologies such as ADSL. Historically, telcos have been cautious
in implementing new technologies. Telcos' deployment of ADSL technology may be
prevented or delayed by a number of factors, including telcos' lengthy product
approval and purchase processes, telcos' decisions to defer product orders in
anticipation of new product developments, cost, regulatory barriers that prevent
or restrict telcos from providing interactive multimedia services, the lack of
demand for interactive multimedia services, the lack of sufficient programming
for interactive multimedia services, the availability of alternative
technologies, such as
 
                                        5
<PAGE>   9
 
Integrated Service Digital Network ("ISDN"), cable modems and optical fiber, and
telco policies that favor the use of such alternative technologies over ADSL
technology. As a result of these factors, there can be no assurance that telcos
will pursue the deployment of products using ADSL technology. Even if telcos
adopt policies favoring full-scale implementation of ADSL technology, there is
no assurance that sales of the Company's ADSL systems will become significant or
that the Company will be able to successfully introduce on a timely basis or
achieve sales of ADSL systems and other products based upon DSL technology
planned for future introduction. Due to increased competition, low barriers to
entry, product pricing pressures and new product introductions in the Company's
core Digital Signal Hierarchy Level 0 ("DS0") and Digital Signal Hierarchy Level
1 ("DS1") markets, these DS0 and DS1 product groups are not expected to generate
sufficient revenues or profits to offset any losses that the Company may
experience due to a lack of sales of ADSL systems and other DSL products
currently under development. As a result, if telcos fail to deploy the Company's
ADSL systems, and the Company therefore does not receive significant revenues
from ADSL sales, then the Company's business and results of operations will be
materially adversely affected and there can be no assurance that the Company
will achieve profitability in the future. See "Business -- Industry Overview"
and "Business -- Products."
 
FLUCTUATIONS IN QUARTERLY RESULTS; LACK OF BACKLOG
 
     The Company has experienced, and expects to continue to experience,
significant fluctuations in its quarterly results of operations. Factors which
have had an influence on and may continue to influence the Company's results of
operations in a particular quarter include the size and timing of customer
orders and subsequent shipments, customer order deferrals in anticipation of new
products, timing of product introductions or enhancements by the Company or its
competitors, market acceptance of new products, technological changes in the
telecommunications industry, competitive pricing pressures, accuracy of customer
forecasts of end-user demand, changes in the Company's operating expenses,
personnel changes, foreign currency fluctuations, changes in the mix of products
sold, quality control of products sold, disruption in sources of supply,
regulatory changes, capital spending, delays of payments by customers and
general economic conditions. The timing and volume of customer orders are
difficult to forecast because telcos typically require prompt delivery of
products and a substantial majority of the Company's sales are booked and
shipped in the same quarter pursuant to nonbinding purchase agreements. As a
result, the Company has a limited backlog of orders for its products and must
maintain sufficient raw and finished goods inventory levels to satisfy
anticipated customer demand on a timely basis. Maintaining sufficient inventory
levels to assure prompt delivery of the Company's products increases the risk of
inventory obsolescence and associated write-offs, which could have an adverse
effect on the Company's business and results of operations.
 
     Westell intends to continue to make significant ongoing development
expenditures for new products and technologies which may adversely affect
quarter to quarter results of operations. The Company's expense levels are based
in part on expectations of future revenues and are relatively fixed in the short
term. The Company has significantly increased, and intends to continue to
increase, operating expenditures and inventory, particularly as the Company
expands its operations to develop and market products based upon ADSL
technology. Consequently, a shortfall in quarterly revenues due to a lack of
sales of ADSL systems or otherwise would adversely affect the Company's business
and results of operations in a given quarter due to the Company's inability to
adjust expenses or inventory to match revenues for that quarter. In addition,
while warranty returns to date have been relatively insignificant, there can be
no assurance that warranty returns will not increase as the Company increases
its sales of products based upon emerging technology such as its ADSL systems.
Increases in warranty returns in excess of those experienced by the Company to
date may have an adverse effect on the Company's quarterly results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business -- Manufacturing."
 
RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW PRODUCTS
 
     The markets for the Company's products are characterized by intense
competition, rapid technological advances, evolving industry standards, changes
in end-user requirements, frequent new product introductions and enhancements,
and evolving telco service offerings. If technologies or standards applicable to
the
 
                                        6
<PAGE>   10
 
Company's products (or telco service offerings based on the Company's products)
become obsolete or fail to gain widespread commercial acceptance, then the
Company's business and results of operations will be materially adversely
affected. Moreover, the introduction of products embodying new technology, the
emergence of new industry standards or changes in telco services could render
the Company's existing products, as well as products under development, obsolete
and unmarketable. The Company believes that the continued deployment of new
technologies in the U.S., such as High bit-rate Digital Subscriber Line
("HDSL"), in the local access network will adversely affect demand for certain
of its existing products such as NIUs, which accounted for 45.5% of the
Company's revenues in fiscal 1996, and that its future success will largely
depend upon its ability to continue to enhance its existing products and to
successfully develop and market new products on a cost-effective and timely
basis. In this regard, most of the Company's current product offerings apply
primarily to the delivery of digital communications over copper wire in the
local access network. While the Company has competed successfully to date by
developing high performance products for transmission over copper wire, it
expects that the increasing deployment of fiber and wireless broadband
transmission in the local access network (each of which uses a significantly
different process of delivery) will require the Company to develop new products
to meet the demands of these emerging transmission media.
 
     The Company's past sales and profitability have resulted, to a significant
extent, from its ability to anticipate changes in technology, industry standards
and telco service offerings, and to develop and introduce new and enhanced
products. The Company's continued ability to adapt to such changes will be a
significant factor in maintaining or improving its competitive position and its
prospects for growth. Due to rapid technological changes in the
telecommunications industry, the RBOCs' lengthy product approval and purchase
processes and the Company's reliance on third-party technology for the
development of new products, however, there can be no assurance that the Company
will successfully introduce new products on a timely basis or achieve sales of
new products in the future. In addition, there can be no assurance that the
Company will have the financial and manufacturing resources necessary to
continue to successfully develop new products based on emerging technology or to
otherwise successfully respond to changing technology, industry standards and
telco service offerings. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business -- Industry Overview," "Business
- -- Products," "Business -- Research and Product Development" and "Business --
Competition."
 
COMPETITION
 
     The markets for the Company's products are intensely competitive and the
Company expects competition to increase in the future, especially in the
emerging ADSL market. Westell's principal competitors in the DS0 market are
Adtran, Inc., Tellabs, Inc. and Teltrend, Inc. Westell's principal competitors
in the DS1 market are ADC Telecommunications Inc., PairGain Technologies, Inc.
and Teltrend, Inc. The Company's current competitors in the ADSL market include
Alcatel Network Systems, Amati Communications Corp., AT&T Paradyne Corporation
("AT&T Paradyne"), ECI Telecom, Inc., Ericsson, LG Information and
Communications, Ltd., Lucent Technologies, PairGain Technologies, Inc., Orckit
Communications, Ltd. and Performance Telecom Corp. The Company expects
competition in the ADSL market in the near future from numerous other companies.
In addition, the Telecommunications Act of 1996 (the "Telecommunications Act")
which was signed into law on February 8, 1996, permits the RBOCs to engage in
manufacturing activities after the Federal Communications Commission (the "FCC")
authorizes an RBOC to provide long distance services within its service
territory. An RBOC must first meet specific statutory and regulatory tests
demonstrating that its monopoly market for local exchange services is open to
competition before it will be permitted to enter the long distance market. When
these tests are met, an RBOC will be permitted to engage in manufacturing
activities. Therefore, RBOCs, which are the Company's largest customers, may
potentially become the Company's competitors as well. Many of the Company's
competitors and potential competitors have greater financial, technological,
manufacturing, marketing and human resources than the Company. Any increase in
competition could reduce the Company's gross margin, require increased spending
by the Company on research and development and sales and marketing, and
otherwise materially adversely affect the Company's business and results of
operations. See "-- Dependence on Third-Party Technology; Relationship with AT&T
Paradyne."
 
     Products that increase the efficiency of digital transmission over copper
wire face competition from fiber, wireless, cable modems and other products
delivering broadband digital transmission. Many telcos have
 
                                        7
<PAGE>   11
 
adopted policies that favor the deployment of fiber. To the extent that telcos
choose to install fiber and other transmission media between the central office
and the end user, the Company expects that demand for its copper wire-based
products will decline. Telcos face competition from cable operators, new local
access providers and wireless service providers that are capable of providing
high speed digital transmission to end users. To the extent telcos are not
successful in responding to this competition by offering high speed digital
transmission, demand for ADSL systems may not develop. In addition, the
deployment of certain products and technologies for copper wire may also reduce
the demand for the types of products currently manufactured by the Company.
Specifically, the deployment of HDSL in the U.S., which reduces telcos' need for
T-1 repeaters and NIUs, may result in a decrease in demand for Westell's
DS1-based products. Further, the Company believes that the domestic market for
many of its DS0-based products is decreasing, and will likely continue to
decrease, as high capacity digital transmission becomes less expensive and more
widely deployed. See "Business -- Competition," "Business -- Marketing, Sales
and Distribution" and "Business -- Government Regulation."
 
DEPENDENCE ON LIMITED NUMBER OF CUSTOMERS; LENGTHY SALES CYCLES
 
     The Company depends, and will continue to depend, on the RBOCs and other
independent local exchange carriers for substantially all of its revenues. Sales
to the RBOCs accounted for 72.6%, 74.3% and 53.8% of the Company's revenues in
fiscal 1994, 1995 and 1996, respectively. Consequently, the Company's future
success will depend significantly upon the timeliness and size of future
purchase orders from the RBOCs, the product requirements of the RBOCs, the
financial and operating success of the RBOCs, and the success of the RBOCs'
services that use the Company's products. Any attempt by an RBOC or other telco
to seek out additional or alternative suppliers or to undertake, as permitted
under applicable regulations, the internal production of products would have a
material adverse effect on the Company's business and results of operations. In
addition, the Company's sales to its largest customers have in the past
fluctuated and in the future are expected to fluctuate significantly from
quarter to quarter and year to year. The loss of such customers or the
occurrence of such sales fluctuations would materially adversely affect the
Company's business and results of operations. Bell Atlantic and NYNEX and
Pacific Telesis and SBC Communications, respectively, have recently announced
their intent to merge. The Company is unable to predict what effect either of
these mergers, if completed, would have on the demand for the Company's ADSL
systems or other products. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Business -- Customers" and
"Business -- Government Regulation."
 
     The RBOCs and the Company's other customers are significantly larger than,
and are able to exert a high degree of influence over, the Company. Prior to
selling its products to telcos, the Company must undergo lengthy approval and
purchase processes. Evaluation can take as little as a few months for products
that vary slightly from existing products or up to a year or more for products
based on new technologies such as ADSL. Accordingly, the Company is continually
submitting successive generations of its current products as well as new
products to its customers for approval. The length of the approval process can
vary and is affected by a number of factors, including the complexity of the
product involved, priorities of telcos, telcos' budgets and regulatory issues
affecting telcos. The requirement that telcos obtain FCC approval for certain
new telco services prior to their implementation has in the past delayed the
approval process. There can be no assurance that such delays, if experienced in
the future, will not have a material adverse affect on the Company's business
and results of operations. While the Company has been successful in the past in
obtaining product approvals from its customers, there can be no assurance that
such approvals or that ensuing sales of such products will continue to occur.
Even if demand for the Company's products is high, the RBOCs have sufficient
bargaining power to demand low prices and other terms and conditions that may
materially adversely affect the Company's business and results of operations.
See "Business -- Marketing, Sales and Distribution."
 
DEPENDENCE ON THIRD-PARTY TECHNOLOGY; RELATIONSHIP WITH AT&T PARADYNE
 
     Many of the Company's products incorporate technology developed and owned
by third parties. Consequently, the Company must rely upon third parties to
develop and introduce technologies that enhance the Company's current products
and enable the Company, in turn, to develop its own products on a timely and
cost-effective basis to meet changing customer needs and technological trends in
the telecommunications industry. Any impairment or termination of the Company's
relationship with any licensor of third-party
 
                                        8
<PAGE>   12
 
technology would force the Company to find other developers on a timely basis or
develop its own technology. There can be no assurance that the Company will be
able to obtain the third-party technology necessary to continue to develop and
introduce new and enhanced products, that the Company will obtain third-party
technology on commercially reasonable terms or that the Company will be able to
replace third-party technology in the event such technology becomes unavailable,
obsolete or incompatible with future versions of the Company's products. The
absence, or any significant delay in the replacement, of third-party technology
would have a material adverse effect on the Company's business and results of
operations.
 
     The Company's ADSL products are dependent upon a carrierless
amplitude/phase modulation ("CAP") DSL technology known as GlobeSpan(TM) that
the Company licenses from AT&T Paradyne. AT&T Paradyne is currently the sole
provider of this CAP DSL technology and the Company currently would not be able
to produce any of its ADSL systems without using this technology. The license
between AT&T Paradyne and the Company (the "AT&T License"), which expires in
December 2002, is nonexclusive and this technology has been licensed to numerous
manufacturers. The Company has entered into cooperation and development
agreements with other technology suppliers who are developing alternative DSL
technologies, such as discrete multi-tone ("DMT") DSL technology. Under one such
arrangement, the Company is currently testing prototypes of an alternative DSL
technology. Consequently, in the event AT&T Paradyne fails to renew the AT&T
License, the Company believes that it will have sufficient access to alternative
sources of DSL technology prior to December 2002 so that it will be able to
continue to produce ADSL systems. However, the cancellation or failure of AT&T
Paradyne to renew the AT&T License would materially adversely affect the
Company's business and results of operations if other sources of DSL technology
do not become readily available on similar terms or telcos elect not to deploy
ADSL systems utilizing alternative DSL technologies, such as DMT DSL technology.
 
     In addition, AT&T Paradyne has formed a business unit that develops and
markets products competitive with the Company's products, such as ADSL. Although
this newly-formed business unit does not affect the Company's AT&T License and
is an independent unit from the business unit licensing CAP DSL technology,
there can be no assurance that the formation of this business unit will not
affect the Company's ability to license CAP DSL technology from AT&T Paradyne
after the AT&T License expires. In addition, AT&T Corporation announced that it
intends to sell AT&T Paradyne. The Company is unable to predict what effect, if
any, such a sale would have on the Company's relationship with AT&T Paradyne or
on AT&T Paradyne's licensing of its CAP DSL technology or future technology to
the Company or others. In the event that AT&T Paradyne is sold to a competitor
of the Company, the Company's ability to continue to license CAP DSL technology
after December 2002 may be adversely affected. See "Business -- Proprietary
Rights."
 
DEPENDENCE ON SOLE OR LIMITED SOURCE SUPPLIERS
 
     Certain key components, such as integrated circuits and other electronic
components, used in the Company's products are currently available from only one
source or a limited number of suppliers. For instance, the Company currently
depends on a division of Lucent Technologies (formerly known as AT&T
Microelectronics) to provide critical integrated circuits used in the Company's
ADSL products. The Company purchases integrated circuits from Lucent
Technologies on a purchase order basis and does not have any formal supply
arrangements with Lucent Technologies. In addition, certain electronic
components are currently in short supply and are provided on an allocation basis
to the Company and other users based upon past usage. There can be no assurance
that the Company will be able to continue to obtain sufficient quantities of
integrated circuits or other electronic components as required, or that such
components, if obtained, will be available to the Company on commercially
reasonable terms. In addition, the Company anticipates that integrated circuit
production capacity and availability of certain electronic components from its
suppliers may be insufficient to meet demand in the future. Integrated circuits
and other electronic components are key components in most of the Company's
products and are fundamental to the Company's business strategy of developing
new and succeeding generations of products at reduced unit costs without
compromising functionality or serviceability. In the past, however, the Company
has experienced delays in the receipt of certain of its key components, such as
integrated circuits, which have resulted in delays in related product
deliveries. There can be no assurance that delays in key components or product
deliveries will not occur in the future due to shortages
 
                                        9
<PAGE>   13
 
resulting from the limited number of suppliers, the financial or other
difficulties of such suppliers, or the possible limitations in integrated
circuit production capacity or electronic component availability because of
significant worldwide demand for these components. The inability to obtain
sufficient key components or to develop alternative sources for such components,
if and as required in the future, could result in delays or reductions in
product shipments, which in turn could have a material adverse effect on the
Company's customer relationships and its business and results of operations. See
"Business -- Manufacturing."
 
GOVERNMENT REGULATION
 
     Federal and state regulatory agencies, including the FCC and various state
public utility and service commissions, regulate most of the Company's domestic
customers. While such regulation does not affect the Company directly, the
effects of such regulation on the Company's customers may, in turn, adversely
impact the Company's business and results of operations. For example, FCC
regulatory policies affecting the availability of telco services, and other
terms on which telcos conduct their business, may impede the Company's
penetration of certain markets. The Telecommunications Act lifted certain
restrictions on telcos' ability to provide interactive multimedia services
including video-on-demand. The Telecommunications Act establishes new
regulations whereby telcos may provide various types of video services. Rules to
implement these new statutory provisions are now being considered by the FCC.
While the statutory and regulatory framework for telcos providing video products
has become more favorable, it is uncertain at this time how this will affect
telcos demand for products based upon ADSL technology. In addition, the
Company's business and results of operations may also be adversely affected by
the imposition of certain tariffs, duties and other import restrictions on
components which the Company obtains from non-domestic suppliers, or by the
imposition of export restrictions on products which the Company sells
internationally. Changes in current or future laws or regulations, in the U.S.
or elsewhere, could materially adversely affect the Company's business and
results of operations.
 
     In addition, the Telecommunications Act permits the RBOCs to engage in
manufacturing activities after the FCC authorizes an RBOC to provide long
distance services within its service territory. An RBOC must first meet specific
statutory and regulatory tests demonstrating that its monopoly market for local
exchange services is open to competition before it will be permitted to enter
the long distance market. When these tests are met, an RBOC will be permitted to
engage in manufacturing activities and the RBOCs, which are the Company's
largest customers, may become the Company's competitors as well. See "Business
- -- Government Regulation."
 
POTENTIAL PRODUCT RECALLS; WARRANTY EXPENSES
 
     The Company's products are required to meet rigorous standards imposed by
its customers. Most of the Company's products carry a limited warranty ranging
from two to seven years, which generally covers defects in materials or
workmanship and failure to meet published specifications, but excludes damages
caused by improper use and all other express or implied warranties. In the event
there are material deficiencies or defects in the design or manufacture of the
Company's products, the affected products could be subject to recall. For the
past five fiscal years, the Company's warranty expenses have been relatively
insignificant. Although the Company maintains a comprehensive quality control
program, there can be no assurance that the Company's products will not suffer
from defects or other deficiencies or that the Company will not experience a
material product recall in the future. Complex products such as those offered by
the Company may contain undetected errors or failures when first introduced or
as new versions are released. Any product recall as a result of such errors or
failures, and the associated negative publicity, could result in the loss of or
delay in market acceptance of the Company's products and have a material adverse
effect on the Company's business and results of operations. The Company's
standard limited warranty for its ADSL products ranges from two to five years.
Since the Company's ADSL products are new, with limited time in service, the
Company cannot predict the level of warranty claims that it will experience for
these products. Despite testing by the Company and its customers, there can be
no assurance that existing or future products based on ADSL or other technology
will not contain undetected errors or failures when first introduced or as new
versions are released. Such errors or failures could result in warranty returns
in excess of those historically experienced by the Company and have a material
adverse effect on the Company's business and results of operations. See
"Business -- Customer Service and Support."

RISKS DUE TO EXPANDING INTERNATIONAL OPERATIONS
 
     International revenues represented 5.0% and 23.8% of the Company's revenues
in fiscal 1995 and 1996, respectively. The Company believes that international
revenues will represent a significant percentage of revenues in the future. Due
to its export sales, the Company is subject to the risks of conducting business
internationally, including unexpected changes in regulatory requirements,
foreign currency fluctuations which could result in reduced revenues or
increased operating expenses, tariffs and trade barriers, potentially longer
payment cycles, difficulty in accounts receivable collection, foreign taxes, and
the burdens of complying with a variety of foreign laws and telecommunications
standards. The Company's contracts with its international customers are
typically denominated in foreign currency and any decline in the value of such
currency could have a significant impact on the Company's business and results
of operations. For example, in fiscal 1996, the Company incurred a $270,000
transaction loss on receivables due to foreign currency fluctuations. To date,
the Company has not engaged in hedging with respect to its foreign currency
exposure but may do so in the future. The Company 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. In addition, the laws of certain foreign countries may not protect
the Company's proprietary technology to the same extent as do the laws of the
U.S. There can be no assurance that the risks associated with the Company's
international operations will not materially adversely affect the Company's
business and results of operations in the future or require the Company to
modify significantly its current business practices. See "Business --
Customers."
 
FACTORS AFFECTING ABILITY TO MANAGE AND SUSTAIN GROWTH
 
     Since fiscal 1992, the Company has experienced a period of rapid growth
which has placed, and is expected to continue to place, a significant strain on
the Company's management, operational and financial resources. The Company's
growth is expected to require the addition of new management personnel and the
development of additional expertise by existing management personnel. The
Company's ability to manage growth effectively, particularly given the
increasingly international scope of its operations, will require it to continue
to implement and improve its operational, financial and management information
systems, to develop the management skills of its managers and supervisors and to
train, motivate and manage its employees. In addition, the Company currently
manufactures most of its products internally and is in the process of developing
the manufacturing capabilities necessary to supply and support large volumes of
ADSL systems. As part of its strategic plan to meet the potential worldwide
demand for its ADSL systems, the Company has entered into discussions to
establish subcontracting relationships for the assembly of its ADSL systems and
in the future may become increasingly dependent on subcontractors. There can be
no assurance that the Company will be successful in increasing its manufacturing
capacity in a timely and cost-effective manner or that the possible transition
to subcontracting will not materially adversely affect the Company's business
and results of operations. The Company's failure to effectively manage its
growth would have a material adverse effect on the Company's business and
results of operations.
 
PROPRIETARY TECHNOLOGY; RISK OF THIRD-PARTY CLAIMS OF INFRINGEMENT
 
     The Company's success and future revenue growth will depend, in part, on
its ability to protect trade secrets, obtain or license patents and operate
without infringing on the rights of others. Although the Company regards its
technology as proprietary, it currently has only one patent on such technology.
The Company relies on a combination of technical leadership, trade secrets,
copyright and trademark law and nondisclosure agreements to protect its
unpatented proprietary know-how. There can be no assurance, however, that these
measures will provide meaningful protection for the Company's trade secrets or
other proprietary information. Moreover, the Company's business and results of
operations may be materially adversely affected by competitors who independently
develop substantially equivalent technology. In addition, the telecommunications
industry is characterized by the existence of an increasing number of patents
and frequent litigation based on allegations of patent and other intellectual
property infringement. From time to time, the Company receives communications
from third parties alleging infringement of exclusive patent, copyright and
other intellectual property rights to technologies that are important to the
Company. There can be no assurance that third parties will not assert
infringement claims against the Company in the future, that assertions by such
 
                                       11
<PAGE>   15
 
parties will not result in costly litigation, or that the Company would prevail
in any such litigation or be able to license any valid and infringed patents
from third parties on commercially reasonable terms. Further, such litigation,
regardless of its outcome, could result in substantial costs to and diversion of
effort by the Company. Any infringement claim or other litigation against or by
the Company could have a material adverse effect on the Company's business and
results of operations. See "Business -- Proprietary Rights."
 
DEPENDENCE ON KEY PERSONNEL
 
     The success of the Company is dependent, in part, on its ability to attract
and retain qualified technical, marketing, sales and management personnel.
Competition for such personnel is intense and the Company's inability to attract
and retain additional key employees or the loss of one or more of its current
key employees could materially adversely affect the Company's business and
results of operations. The Company does not have employment contracts or
noncompete agreements with any of its executive officers except Richard Riviere,
the Vice President of Transaction Services and President of Conference Plus,
Inc., a subsidiary of the Company. Mr. Riviere has agreed not to compete with
the Company for two years after the termination of his employment with the
Company. There can be no assurance that the Company will be successful in hiring
or retaining key personnel. See "Management."
 
EXPECTED VOLATILITY OF STOCK PRICE
 
     The market price of the Company's Class A Common Stock has risen
substantially since the Company's initial public offering in November 1995. The
Class A Common Stock is quoted on the Nasdaq National Market, which market has
experienced and is likely to experience in the future significant price and
volume fluctuations. The trading prices of many technology stocks are at or near
their historical highs and reflect price/earnings ratios substantially above
historical norms. There can be no assurance that these trading prices and
price/earnings ratios will be sustained. Market fluctuations may adversely
affect the market price of the Company's Class A Common Stock without regard to
the operating performance of the Company. In addition, the Company believes that
factors such as announcements of developments related to the Company's business,
fluctuations in the Company's results of operations, sales of substantial
amounts of securities of the Company into the marketplace, general conditions in
the telecommunications industry or the worldwide economy, an outbreak of
hostilities, a shortfall in revenues or earnings compared to analysts'
expectations, changes in analysts' recommendations or projections, announcements
of new products by the Company or its competitors or developments in the
Company's relationships with its suppliers or customers could cause the price of
the Class A Common Stock to fluctuate in the future, perhaps substantially.
There can be no assurance that the market price of the Company's Class A Common
Stock will not experience significant fluctuations in the future, including
fluctuations that are unrelated to the Company's performance. General market
price declines or market volatility in the future could adversely affect the
market price of the Class A Common Stock, and the current market price of the
Class A Common Stock may not be indicative of future market prices.
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
     Sales of substantial amounts of Class A Common Stock (including shares
issuable upon conversion of outstanding Class B Common Stock) in the public
market following this offering could adversely affect the market price of the
Class A Common Stock. Upon the completion of this offering, all outstanding
shares of Common Stock will be either freely tradeable in the public market or
will be eligible for immediate public sale subject (i) to certain rights of
first refusal held by members of the Robert C. Penny III family with respect to
19,552,938 shares held pursuant to a Voting Trust Agreement dated February 23,
1994, as amended (the "Voting Trust"), among Robert C. Penny III and Melvin J.
Simon, as trustees (the "Trustees"), and members of the Penny family (as defined
in the Voting Trust) and Simon family (as defined in the Voting Trust) and (ii)
in the case of certain shares, to the volume and manner of sale limitations
imposed by Rule 144 under the Securities Act. Holders of 24,957,806 shares have,
subject to certain limited exceptions, agreed not to sell or offer to sell or
otherwise dispose of the shares of Common Stock currently held by them, any
options or warrants to purchase any shares of Common Stock or any securities
convertible into or exchangeable for any shares of Common Stock for a period of
90 days after the date of this Prospectus without
 
                                       12
<PAGE>   16
 
the prior written consent of Montgomery Securities. In addition, as Trustees
under the Voting Trust, beginning 90 days after the date of this Prospectus,
Robert C. Penny III and Melvin J. Simon, as Trustees of the Voting Trust, are
entitled to certain registration rights with respect to the 19,552,938 shares of
Class A Common Stock issuable upon conversion of the Class B Common Stock held
in the Voting Trust. In addition, the Company has registered an aggregate of
2,876,958 shares of Class A Common Stock reserved for issuance under the Stock
Purchase Plan and the Stock Incentive Plan. The issuance of shares under the
Stock Purchase Plan and the Stock Incentive Plan will result in the dilution of
the voting power of the shares of Class A Common Stock purchased in this
offering and could have a dilutive effect on the Company's earnings per share.
See "Management -- Stock Plans," "Description of Capital Stock," "Shares
Eligible for Future Sale" and "Underwriting."
 
CONTROL BY PRINCIPAL STOCKHOLDERS
 
     The Company's capital stock consists of Class A Common Stock and Class B
Common Stock. Holders of Class A Common Stock are entitled to one vote per share
and holders of the Class B Common Stock are entitled to four votes per share. As
Trustees of the Voting Trust, immediately following this offering, Robert C.
Penny III and Melvin J. Simon will have the exclusive power to vote 53.9% of the
outstanding shares of Common Stock, which constitute 78.2% of the votes entitled
to be cast by the holders of the Company's Common Stock, according to the mutual
determination by Messrs. Penny and Simon as to the best interests of the
beneficiaries of the Voting Trust, consisting of the Penny family and the Simon
family. In addition, all members of the Penny family who are beneficiaries under
the Voting Trust are parties to a Stock Transfer Restriction Agreement which
prohibits such beneficiaries from transferring any Common Stock or their
beneficial interests in the Voting Trust acquired prior to the date of this
Prospectus without first offering such Common Stock to the other members of the
Penny family. Consequently, Messrs. Penny and Simon, as Trustees, will
effectively control the Company and generally have sufficient voting power to
elect all of the directors and to determine the outcome of any corporate
transaction or other matter submitted to the stockholders for approval. Such
control may have the effect of discouraging certain types of transactions
involving an actual or potential change of control of the Company, including
transactions in which the holders of Class A Common Stock might otherwise
receive a premium for their shares over the then-current market price. See
"Principal and Selling Stockholders" and "Description of Capital Stock."
 
ANTI-TAKEOVER PROVISIONS
 
     The Company's Board of Directors has the authority to issue up to 1,000,000
shares of Preferred Stock and to determine the relative preferences, limitations
and relative rights of those shares with respect to dividends, redemption,
payments on liquidation, sinking fund provisions, conversion privileges and
voting rights without any further vote or action by the stockholders. The rights
of the holders of Class A Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any Preferred Stock that may be issued
in the future. While the Company has no present intention to issue shares of
Preferred Stock, any such issuance could have the effect of making it more
difficult for a third party to acquire control of the Company. In addition, the
Company is subject to the anti-takeover provisions of Section 203 of the
Delaware General Corporation Law, which could have the effect of delaying or
preventing a change of control of the Company. Furthermore, certain provisions
of the Company's Amended and Restated Certificate of Incorporation (the "Amended
Certificate of Incorporation") and By-laws may individually or collectively have
the effect of delaying or preventing changes in control or management of the
Company and could have a depressive effect on the market price of the Company's
Class A Common Stock. For example, the Company's Amended Certificate of
Incorporation and By-laws contain provisions that limit the right of
stockholders to call special stockholders meetings and require that stockholders
follow an advance notification procedure for certain stockholder nominations of
candidates to the Board of Directors and for new business to be conducted at
stockholders meetings. See "Description of Capital Stock."
 
NO DIVIDENDS
 
     The Company intends to retain all future earnings for use in the
development of its business and does not anticipate paying any cash dividends in
the foreseeable future.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,665,000 shares of
Class A Common Stock offered by the Company hereby, based upon an assumed public
offering price of $38 1/8 per share, after deducting the underwriting discount
and estimated offering expenses, are estimated to be approximately $60.2 million
($65.8 million if the Underwriters' over-allotment option is exercised in full).
The Company will not receive any proceeds from the sale of the shares by the
Selling Stockholders.
 
     The Company estimates that it will use approximately $6.0 million of the
net proceeds to purchase capital equipment. The Company expects to use the
remaining proceeds for general corporate purposes, including working capital and
possible acquisitions of businesses, technologies or products complementary to
the Company's business. Although the Company may pursue acquisition
opportunities in the future, there are no present understandings, commitments or
agreements with respect to any such acquisitions. Pending such uses, the Company
intends to invest the proceeds in short-term interest-bearing securities.
 
                      PRICE RANGE OF CLASS A COMMON STOCK

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Prospectus contains, in addition to historical information,
forward-looking statements that include risks and uncertainties. The Company's
actual results may differ significantly from the results discussed in the
forward-looking statements. Factors that might cause such a difference include
those discussed below, as well as those discussed elsewhere in this Prospectus.
The Company undertakes no obligation to release publicly the result of any
revisions to these forward-looking statements that may be made to reflect events
or circumstances after the date hereof or to reflect the occurrence of
unanticipated events.
 
OVERVIEW
 
     The Company commenced operations in 1980 as a provider of
telecommunications network transmission products that enable advanced
telecommunications services over copper telephone wires. Until fiscal 1994, the
Company derived substantially all of its revenues from its DS0 and DS1 product
lines, particularly the sale of NIUs and related products, which accounted for
at least 45% of revenues in each of the last three fiscal years. The Company
introduced its first DSL products in fiscal 1993 and these products represented
3.9%, 20.6% and 24.4% of revenues in fiscal 1994, 1995 and 1996, respectively.
The Company has also provided audio teleconferencing services since fiscal 1989
and consumer products claims processing services since fiscal 1994. Revenues
from audio teleconferencing services constituted 9.2% of the Company's revenues
in both fiscal 1995 and 1996. In August 1995, the Company approved a plan for
the disposition of KPINS, its consumer products claims processing subsidiary,
which is presented in the results of operations as a discontinued operation.
 
     The Company's customer base is comprised primarily of the RBOCs,
independent domestic local exchange carriers and public telephone
administrations located outside the U.S. Due to the stringent quality
specifications of its customers and the regulated environment in which its
customers operate, the Company must undergo lengthy approval and procurement
processes prior to selling its products. Accordingly, the Company must make
significant upfront investments in product and market development prior to
actual commencement of sales of new products. In late fiscal 1992, the Company
significantly increased its investment in new product development based on
emerging technologies, particularly ADSL, and began expanding its sales and
marketing efforts to cover new product lines and planned expansion into
international markets. International operations accounted for 5.0% and 23.8% of
the Company's revenues in fiscal 1995 and 1996, respectively. As a result of the
significant increases in research and development and sales and marketing
expenses related to new product and market development, the Company's results of
operations were adversely impacted in fiscal 1994, 1995 and 1996.
 
     The Company expects to continue to evaluate new product opportunities and
engage in extensive research and development activities. This will require the
Company to continue to invest heavily in research and development and sales and
marketing, which is expected to adversely affect short-term results of
operations. Due to the Company's significant ongoing investment in ADSL
technology, the Company anticipates losses in at least the first and second
quarters of fiscal 1997. The Company believes that its future revenue growth and
profitability will principally depend on its success in increasing sales of ADSL
products and developing new and enhanced DS1 and other DSL products. In view of
the Company's reliance on the emerging ADSL market for growth and the
unpredictability of orders and subsequent revenues, the Company believes that
period to period comparisons of its financial results are not necessarily
meaningful and should not be relied upon as an indication of future performance.
Revenues from DS0 products have declined in recent years as telcos continue to
move from analog to digital transmission services. The Company also expects that
revenues from NIU products in its DS1 product group may decline as telcos
increase the use of alternative technologies such as HDSL. Failure to increase
revenues from new products, whether due to lack of market acceptance,
competition, technological change or otherwise, would have a material adverse
effect on the Company's business and results of operations.

FISCAL YEARS ENDED MARCH 31, 1994, 1995 AND 1996
 
     Revenues. Revenues were $51.1 million, $74.0 million and $83.2 million in
fiscal 1994, 1995 and 1996, respectively. Revenues increased 45.0% from fiscal
1994 to 1995 and 12.4% from fiscal 1995 to 1996. The fiscal 1995 increase was
primarily a result of a $13.5 million increase in sales of DSL products, a $7.5
million increase in sales of DS1 products and a $1.4 million increase in
teleconferencing revenues, which was offset in part by a $1.3 million decline in
revenues from DS0 products. The fiscal 1996 increase was primarily due to a $5.1
million increase in DSL products reflecting shipments to two international
customers and a $3.3 million increase in DS1 product revenues.
 
     Gross Margin. Gross margin decreased as a percentage of revenues from 40.7%
in fiscal 1994 to 39.9% in fiscal 1995 and to 39.0% in fiscal 1996. These
decreases were due to product pricing pressures and changes in product mix
within the Company's DS1 and DS0 product lines. These decreases were offset in
part by sales of higher margin ADSL products and an increase in teleconferencing
revenues in fiscal 1995 and 1996.
 
     Sales and Marketing. Sales and marketing expenses were $8.1 million, $12.2
million and $13.7 million in fiscal 1994, 1995 and 1996, respectively,
constituting 15.8%, 16.4% and 16.5% of revenues, respectively. These increases
in sales and marketing expenses were primarily due to staff additions, in both
domestic and international markets, to support and promote the Company's product
lines, particularly ADSL products. The Company believes that continued
investment in sales and marketing will be required to expand its product lines,
bring new products to market and service customers. The Company anticipates that
sales and marketing expenses will continue to increase in absolute dollars.
 
     Research and Development. Research and development expenses were $7.7
million, $10.8 million and $12.6 million in fiscal 1994, 1995 and 1996,
respectively, constituting 15.1%. 14.6% and 15.1% of revenues, respectively.
These increases in research and development expenses were due primarily to new
and existing product development for ADSL and other emerging technology products
and were offset in part by customer nonrecurring engineering funding of $800,000
and $2.6 million in fiscal 1995 and 1996, respectively. The Company believes
that a continued commitment to research and development will be required for the
 
                                       19
<PAGE>   23
 
Company to remain competitive and anticipates that research and development
costs will increase in absolute dollars.
 
     General and Administrative. General and administrative expenses were $5.5
million, $6.7 million and $8.4 million in fiscal 1994, 1995, and 1996
respectively, constituting 10.8%, 9.1% and 10.0% of revenues, respectively. The
fiscal 1995 and fiscal 1996 increases were due primarily to continued expansion
of operations in domestic and international markets. The Company anticipates
that general and administrative costs will continue to increase in absolute
dollars as the Company hires additional personnel.
 
     Interest Expense. Interest expense was $176,000, $769,000 and $859,000 for
fiscal 1994, 1995 and 1996, respectively. Interest expense increased,
particularly in fiscal 1995 and 1996, as a result of interest expense incurred
by the Company in connection with borrowings under its revolving promissory
notes to fund expanded working capital requirements and, to a lesser extent,
interest incurred under capital lease obligations.
 
     Benefit for Income Taxes. Benefit for income taxes were $989,000, $788,000
and $1.9 million in fiscal 1994, 1995, and 1996, respectively. In each of these
fiscal years, in addition to the tax benefit generated by the loss before income
taxes, the Company was able to utilize $724,000, $632,000 and $790,000,
respectively, in tax credits primarily generated by increasing research and
development activities. The Company has approximately $1.8 million in income tax
credit carryforwards and a $1.9 million net operating loss carryforward that are
available to offset future taxable income. The tax credit carryforwards begin to
expire in 2009 and the net operating loss carryforward expires in 2011.

     The Company's revenues increased by $9.8 million in the fourth quarter of
fiscal 1995 compared to the third quarter of fiscal 1995 due to a large shipment
of ADSL systems to one customer when this customer received regulatory approval
for market trial deployment of ADSL systems. The Company has continued to ship
ADSL systems but at a reduced level from that of the fourth quarter of fiscal
1995, which has resulted in a reduction in quarterly revenues compared to the
preceding quarter in three of the four quarters in fiscal 1996. Gross margin as
a percentage of revenues increased from 38.8% in the fourth quarter of fiscal
1995 to 43.0% in the first quarter of fiscal 1996 due to higher margins received
on ADSL products. Gross margin as a percentage of revenues declined to 38.4%,
38.0% and 36.0% in the second, third and fourth quarters of fiscal 1996,
respectively, as a result of product pricing pressures in the DS1 and DS0
product lines as well as investments in manufacturing infrastructure for
anticipated ADSL production. The Company believes that its gross margin in
future periods will depend on a number of factors, including market demand for
the Company's ADSL products, pricing pressures, competitive technologies and
manufacturing expenses. There can be no assurance that the Company will be able
to increase gross margins in future periods even if its ADSL products achieve
market acceptance.
 
     Operating expenses increased during each quarter of fiscal 1995 and the
first three quarters of fiscal 1996 as the Company continued to make significant
investments to support anticipated revenue growth. Operating expenses decreased
in the fourth quarter of fiscal 1996 primarily as a result of nonrecurring
engineering funding from third parties in the amount of $1.1 million which
offset research and development expenses. The Company expects to continue to
increase operating expenses to support the development, introduction and
promotion of ADSL systems and other new products. As a result of fluctuations in
the timing of revenues of ADSL products and increased research and development
and sales and marketing expenses, the Company currently anticipates net losses
in at least the first and second quarters of fiscal 1997. In addition, the
Company recorded approximately $237,000 of compensation expense in the third
quarter of fiscal 1996 as a result of the issuance of 24,624 shares of Class A
Common Stock to employees of the Company. The Company also recorded a charge of
approximately $520,000, net of tax, in the second quarter of fiscal 1996 in
connection with the planned disposition of KPINS.
 
     The Company expects to continue to experience significant fluctuations in
quarterly results of operations. The Company believes that fluctuations in
quarterly results may cause the market price of the Class A Common Stock to
fluctuate, perhaps substantially. Factors which have had an influence on and may
continue to influence the Company's results of operations in a particular
quarter include the size and timing of customer orders and subsequent shipments,
customer order deferrals in anticipation of new products, timing of product
introductions or enhancements by the Company or its competitors, market
acceptance of new products, technological changes in the telecommunications
industry, competitive pricing pressures, accuracy of customer forecasts of
end-user demand, changes in the Company's operating expenses, personnel changes,
foreign currency fluctuations, changes in the mix of products sold, quality
control of products sold, disruption in sources of supply, regulatory changes,
capital spending, delays of payments by customers and general economic
conditions. Sales to the Company's customers typically involve long approval and
procurement cycles and can involve large purchase commitments. Accordingly,
cancellation or deferral of one or a small number of orders could cause
significant fluctuations in the Company's quarterly results of operations. As a
result, the Company believes that period-to-period comparisons of its results of
operations are not necessarily meaningful and should not be relied upon as
indications of future performance.
 
     Because the Company generally ships products within a short period after
receipt of an order, the Company typically does not have a material backlog of
unfilled orders, and revenues in any quarter are substantially dependent on
orders booked in that quarter. The Company's expense levels are based in large
part on anticipated future revenues and are relatively fixed in the short-term.
Therefore, the Company may be unable to adjust spending in a timely manner to
compensate for any unexpected shortfall of orders. Accordingly, any significant
shortfall of demand in relation to the Company's expectations or any material
delay of customer orders would have an almost immediate adverse impact on the
Company's business and results of operations and on its ability to achieve
profitability.

LIQUIDITY AND CAPITAL RESOURCES
 
     In November 1995, the Company effected the initial public offering of its
Class A Common Stock which generated approximately $33.3 million in corporate
funding. The Company used the proceeds from the offering to repay revolving
promissory bank notes of approximately $11.1 million which primarily financed
working capital. The remainder of the proceeds were invested in short term
investments comprised principally of the highest grade commercial paper and
government backed securities with 90-day or less maturity. As of March 31, 1996,
the Company had no amounts outstanding under its secured revolving promissory
notes and $3.8 million outstanding under its equipment financing facility. As of
March 31, 1996, the Company had approximately $15.4 million available under
these facilities. The revolving promissory notes and the equipment financing
facility require the maintenance of a minimum cash to current maturities ratio,
a current ratio and a maximum debt to net worth ratio. The Company is currently
in compliance with all such covenants.
 
     The Company's operating activities generated cash of $3.6 million and $6.5
million in fiscal 1994 and 1996, respectively, and used cash of $5.3 million in
fiscal 1995. Cash generated from operating activities in fiscal 1994 resulted
principally from increases in customer deposits and accounts payable offset in
part by increases in accounts receivable, inventory and prepaid expenses. Cash
used by operations in fiscal 1995 resulted primarily from decreases in customer
deposits and increases in receivables and inventory, offset in part by increases
in accounts payable. Cash generated from operating activities in fiscal 1996 was
a result of decreases in receivables and inventory and an increase in customer
deposits offset in part by a decrease in accounts payable.
 
     Capital expenditures in fiscal 1994, 1995 and 1996 were $6.1 million, $5.2
million, and $6.3 million, respectively. These expenditures were principally for
machinery, computer and research equipment purchases. The Company expects to
spend approximately $6.0 million in fiscal 1997 for capital equipment.
 
     In September 1995, the Company formed a limited liability company ("LLC")
with a real estate developer for the purpose of developing a 16.4 acre site in
Aurora, Illinois into a 173,000 square foot corporate facility to house
manufacturing, engineering, sales, marketing and administration. In connection
therewith, the Company currently has a 98% ownership interest in the LLC, which
will gradually decrease to a 60% ownership interest as the other LLC member
increases its capital contribution to the LLC by contributing its development
fee for the new facility, as earned. In addition, the Company has a
reimbursement obligation with respect to an irrevocable letter of credit issued
for the Company's account in the amount of $952,000, due on or before September
30, 1996, which represents the Company's capital contribution to the LLC. On
September 25, 1995, the Company advanced the LLC $1.4 million for the purchase
of land. The advance is in the form of a short-term note which bears interest at
the prime rate (8.25% at March 31, 1996). The note and accrued interest become
due from the proceeds of the construction financing. During fiscal 1996, the LLC
began construction of the new facility and as of March 31, 1996, $3.0 million of
construction costs were incurred. In September 1995, the Company also entered
into a 15-year lease for the facility being developed by the LLC. Pursuant to
the terms of the LLC, the Company will have the option to buy out the other
investor in the LLC and thereby purchase the facility being developed by the LLC
or sell its interest in the LLC.
 
     At March 31, 1996, the Company's principal sources of liquidity were $21.8
million of cash and cash equivalents, and $12.8 million and $2.6 million
available under its secured revolving promissory notes and equipment borrowing
facility, respectively. Borrowings under the secured revolving promissory notes
and equipment borrowing facility currently bear interest at the bank's prime
rate (8.25% at March 31, 1996). These revolving promissory notes are due on, and
the equipment borrowing facility expires in, September 1996 and the Company
anticipates that such revolving promissory notes and equipment borrowing
facility will be renewed on no less favorable terms.
 
     The Company had a deferred tax asset of approximately $4.4 million at March
31, 1996. This deferred tax asset relates to (i) tax credit carryforwards of
approximately $1.8 million, (ii) a net operating loss carryforward of
approximately $740,000 and (iii) temporary differences between the amount of
assets and liabilities for financial reporting purposes and such amounts
measured by tax laws. Of such tax credit carryforwards, the first $500,000 of
credits expire in 2009 and $321,000 of credits may be carried forward
indefinitely. The net operating loss carryforward expires in 2011. The remainder
of the deferred tax asset
 
                                       23
<PAGE>   27
 
relates to items deductible for financial income reporting purposes which were
taxable in accordance with tax regulations. Management has not recorded a
valuation allowance and believes that the deferred tax asset will be fully
realized based on current estimates of future taxable income, future reversals
of existing taxable temporary differences or available tax planning strategies.
 
     The Company believes that the net proceeds from this offering, its bank
lines of credit and funds generated from operations, if any, will provide
adequate liquidity to meet the Company's capital and operating requirements
during the twelve-month period following this offering.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     During March 1995 and October 1995, respectively, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" and SFAS No. 123, "Accounting for Stock-Based
Compensation." The Company is required to adopt these standards in fiscal 1997.
The Company does not anticipate that adoption of SFAS No. 121 will have a
material effect on its financial statements. The Company anticipates that it
will provide expanded disclosure in the footnotes to its financial statements,
as prescribed by SFAS No. 123, for activity related to its stock plans.

                                    BUSINESS
 
     Since 1980, Westell has developed telecommunications products that address
the needs of telephone companies ("telcos") to upgrade their existing network
infrastructures continually in order to deliver advanced data and voice services
to their customers. The Company designs, manufactures, markets and services a
broad range of digital and analog products used by telcos to deliver services
primarily over existing copper telephone wires that connect end users to a
telco's central office (the "local access network"). The Company also markets
its products and services to other telecommunications and information service
providers seeking direct access to end-user customers. The Company's principal
customers include all seven Regional Bell Operating Companies (the "RBOCs") as
well as GTE, British Telecom and Telecom Italia. In addition, Westell sells
products to several other entities, including public telephone administrations
located outside the U.S., independent domestic local exchange carriers,
competitive access providers, interexchange carriers and the U.S. federal
government.
 
     Westell is a leading developer and provider of broadband telecommunications
access systems using an emerging technology known as Asymmetric Digital
Subscriber Line ("ADSL"). ADSL systems will allow telcos to provide interactive
multimedia services over existing copper wire, thus offering a more
cost-effective and faster deployment alternative to fiber optic cable in the
"last mile" of the local access network. ADSL systems enable interactive
multimedia services such as advanced data dialtone applications, including high
speed Internet access, local area network ("LAN") extension, telecommuting and
medical imaging, as well as emerging video dialtone applications, including
video-on-demand, distance learning, video conferencing and work at home.
Currently, over 30 domestic and international telcos, including Bell Atlantic,
GTE, US West !nterprise, British Telecom and Telecom Italia, are conducting
technical or marketing trials for new interactive multimedia services that rely
on the Company's ADSL systems. All of these ADSL trials began in 1995 and 1996,
except for the Bell Atlantic trial which commenced in 1993. The Company is
unable to predict the outcome of such trials or when such trials will be
completed. See "-- Marketing, Sales and Distribution."
 
INDUSTRY OVERVIEW
 
     Since the early 1980s, the telecommunications industry has experienced an
increased demand for and growth in the number of services provided to end users.
Not only has traditional telephone voice traffic increased, but the growth of
personal computers and modems has created significant data traffic from a wide
variety of services such as fax, e-mail and online access. For example,
businesses with multiple locations increasingly require geographically dispersed
LANs to be linked in sophisticated wide area networks ("WANs") that must handle
large volumes of telecommunications traffic. In addition, the Internet has
expanded beyond its traditional data transmission and file-sharing functions to
offer e-mail, new data sources, commercial services, transaction processing,
independent bulletin boards, the World Wide Web and voice transmission. Business
and residential based end-user demand for telecommunications services is
expected to continue to grow as telcos and information service providers
increase their offerings of new interactive multimedia services, including data
dialtone applications such as high speed Internet access, LAN extension, medical
imaging and telecommuting, and video dialtone applications such as
video-on-demand, distance learning, video conferencing and work at home. To
handle the growing volume of data communications traffic and to provide faster
and higher quality transmission, telcos and information service providers have
continually upgraded the capacity and speed of their networks.
 
     Deregulation. Deregulation of the telecommunications industry has increased
the number of competitors in the local access network and has further
accelerated telcos' needs to upgrade their networks and increase their
telecommunications service offerings. For example, alternative access providers
have deployed fiber and wireless systems for high volume data transmission to
business centers and other high density metropolitan areas. As alternative
access providers' costs decline and deregulation continues, alternative access
providers are likely to create additional competition for telcos by developing
new products and services for end users. Recent deregulation also allows
interexchange carriers, information service providers and cable operators to
deploy competitive services in the local access network. Currently available
high speed cable modems will enable cable operators to provide data transmission
services to customers in addition to standard television services. Cable
operators are seeking to compete with telcos in the delivery of high speed
digital transmission
 
                                       25
<PAGE>   29
 
as well as traditional local telephone service. In addition, this trend toward
continued deregulation of the telecommunications industry may further decrease
the current restrictions and regulations affecting telcos' ability to provide
nontraditional telco services such as video-on-demand.
 
     Existing Telco Infrastructure. Traditionally, telcos have provided local
access services using analog technology, which does not have the bandwidth or
functionality to support the growing demand for new services over telephone
wires. In contrast, digital technology permits high speed, high volume and
reliable data transmission by reducing all forms of images, sounds and data to
digital signals, thereby increasing the variety and bandwidth of services that
can be provided in the local access network. To handle the growing demand for
digital traffic, telcos have deployed broadband optical fiber in their network
"backbone" interconnecting their geographically dispersed central offices.
Telcos have also used fiber to interconnect their central offices to high
density telecommunications traffic areas. Deployment of fiber in the local
access network connecting end users to a telco's central office, however, has
proven labor intensive, complicated, time consuming and expensive. Consequently,
this "last mile" of the telco's network still predominantly consists of low
speed analog transmission over copper wire.
 
     Given the challenges of widespread replacement of copper wire in the local
access network, telcos have turned to systems suppliers for cost-effective
technology that can expand the ability of the existing copper wire
infrastructure to accommodate high speed digital transmission. Digital
conversion of the analog network has been built on the multiplexing format known
as T-1 (E-1 in most countries outside of the U.S.). T-1/E-1 transmission
utilizes a data rate of 1.544 (2.048 outside the U.S.) Megabits per second
("Mbps"), which can be aggregated or subdivided into channels to deliver data
communication services tailored to specific end-user requirements.
 
     Existing and Emerging Technologies. Systems suppliers have developed, and
are currently developing, numerous products that have increased the quality,
speed and cost-effectiveness of digital transmission over copper wire. These
products include:
 
          ISDN. In the early 1980s, telcos introduced basic rate Integrated
     Service Digital Network ("ISDN") technology, which provides digital
     transmission at rates up to 144 Kilobits per second ("Kbps") as well as a
     means to aggregate multiple channels into a single higher speed link over
     copper wire. Telcos have only recently begun to widely deploy basic rate
     ISDN technology with the emergence of nationwide standards and a decline in
     costs for basic rate ISDN service. The market penetration of existing basic
     rate ISDN technology, however, may be constrained due to its limited
     bandwidth, which does not allow telcos to offer advanced data and video
     dialtone services, its inability to provide existing telephone service over
     the same wire and its relatively high installation costs.
 
          HDSL. In 1992, telcos introduced High bit-rate Digital Subscriber Line
     ("HDSL") technology, which reduces the costs of installing and upgrading
     T-1/E-1 service. Traditional T-1/E-1 service requires the installation of
     one or more mid-span repeaters for line lengths greater than 3,000 feet and
     the expensive and time consuming "conditioning" of copper wire. HDSL
     increases the non-repeatered distance of T-1/E-1 transmission (1.544/2.048
     Mbps) over two pairs of copper wires to approximately 12,000 feet, which
     reduces the need for repeaters and conditioning. As a result, telcos are
     deploying HDSL technology in their local access networks where the end user
     requires only one digital communication stream and does not require a
     telephone channel to run on the same wire.
 
          ADSL. An emerging technology known as ADSL permits even greater
     digital transmission capacity over copper wire than is possible with
     existing HDSL and ISDN products. ADSL technology allows the simultaneous
     transmission of data at speeds from 1.5 to 8.0 Mbps in one direction and
     from 64 to 640 Kbps in the reverse direction, while also providing standard
     analog telephone service over a single pair of copper wires at distances of
     up to 18,000 feet, depending on the transmission rate. ADSL products enable
     telcos to provide interactive multimedia services over copper wire, such as
     high speed Internet access, video-on-demand, medical imaging, video
     conferencing and telecommuting, while simultaneously carrying traditional
     telephone services. A new ADSL technology called Very High Speed Digital
     Subscriber Line ("VDSL") is currently being developed that will increase
     both the downstream and upstream data transmission capacity to up to 52.0
     Mbps and 2.0 Mbps, respectively.
 
                                       26
<PAGE>   30
 
          RADSL and SDSL. Products and technologies continue to be developed to
     expand the local access network's capability to transmit high speed digital
     data as well as reduce telcos' costs in providing traditional analog
     services. To increase utilization of broadband copper wire transmission,
     manufacturers are currently developing Rate Adaptive ADSL ("RADSL") systems
     that will automatically adjust the digital transmission rate based upon the
     quality of the copper telephone wire and the distance transmitted in order
     to maximize the digital capacity of the wire and to facilitate the
     installation of ADSL systems. Symmetric Digital Subscriber Line ("SDSL")
     technology is being designed and developed which, in contrast to current
     HDSL and ISDN systems, can provide both a digital and an analog channel
     over a single pair of copper wires.
 
THE WESTELL SOLUTION
 
     Westell designs, manufactures and markets a broad range of
telecommunications products that provide its telco customers with dependable,
high quality transmission systems in the local access network. The Company
believes that its extensive experience in the local access network strategically
positions it to identify product applications that will enhance existing telco
services as well as expand telco service offerings to end users. Westell is a
leading provider of ADSL systems, which allow telcos to provide high speed
interactive multimedia services over existing copper wire, thus offering a
cost-effective alternative to the deployment of fiber optic cable in the "last
mile" of the local access network. Westell's ADSL systems also enable telcos to
use their existing infrastructures to respond to competition from cable
operators that may offer these services using cable modems. The Company
continues to aggressively develop products based upon new technologies, such as
ADSL and SDSL, as well as enhance its existing product offerings in the analog,
digital and digital subscriber line ("DSL") markets. In the last decade, Westell
has introduced a number of intelligent products that enable telcos to increase
productivity and transmission quality over their local access networks through
self-diagnostic and performance monitoring applications. For example, in 1986,
Westell introduced NIUs, which provide maintenance and performance monitoring
capabilities to aid telcos in the provisioning and maintenance of T-1 lines.
Westell also continues to focus on the relationships that it has built with its
customers during its 16-year history. Rapid technological evolution has provided
the Company with an opportunity to forge strategic alliances with customers and
technology suppliers in order to accelerate the time to market for new products.
In addition, the Company continues to redefine its products to increase their
functionality and interface capacity with other products while decreasing
product costs in order to achieve mass deployment of ADSL systems and to
facilitate the numerous applications of high speed digital transmission required
by telcos' consumers.
 
STRATEGY
 
     Westell's objective is to be a global leader in providing low cost and high
quality local access network products that enable telcos to meet the growing
demand for digital service offerings. Key elements of the Company's strategy
include:
 
          Leverage Global Leadership in ADSL Market. The Company seeks to
     leverage its leadership position in the ADSL market to capture emerging
     global market opportunities as telcos expand their interactive multimedia,
     data and video dialtone services. Currently over 30 domestic and
     international telcos, including Bell Atlantic, GTE, US West !nterprise,
     British Telecom and Telecom Italia, are conducting technical or marketing
     trials for new services that rely on the Company's ADSL systems. The
     Company is currently defining broadband access systems based on RADSL and
     SDSL technology, which are expected to complement the Company's ADSL
     systems and the Company believes will have performance advantages over
     alternative ISDN and HDSL systems.
 
          Deliver Mass Market Solutions for High Speed Online and Internet
     Access Services. Due to the rapid emergence and end-user interest in online
     information services, the Internet and the World Wide Web, the Company
     intends to work with telcos and information service providers to deliver
     advanced, high speed data dialtone solutions for these applications as well
     as additional services, such as video
 
                                       27
<PAGE>   31
 
     dialtone applications, as they become available. To facilitate mass market
     deployment of its ADSL systems, the Company is undertaking a program to
     increase the level of integration among its products and improve economies
     of scale. The Company seeks to expand the development of ADSL systems in
     the consumer market by creating ADSL software and hardware interfaces that
     support multiple consumer applications.
 
          Continue to Create Strategic Relationships and Alliances. The Company
     intends to continue to forge strategic relationships and alliances with key
     customers and suppliers. The Company has established strategic
     relationships to facilitate the Company's ability to develop products that
     anticipate customers' product needs. For example, Westell has entered into
     an alliance with Microsoft Corporation whereby Westell's FlexCAP ADSL
     modems will be compatible with Microsoft Corporation's Windows NT(R) Server
     Network. In addition, Westell's relationships with technology leaders such
     as AT&T Paradyne and Analog Devices, Inc. enable the Company to obtain
     emerging technologies required in its product development. These
     relationships allow the Company to focus on product applications and to
     develop products using multiple emerging technologies.
 
          Maintain Core Business Strength and Develop New Products. The Company
     has extensive experience in developing and marketing products for the local
     access network and has achieved a leading position in T-1 network interface
     and performance monitoring units. The Company intends to continue to
     capitalize upon its DS0 and DS1 product development experience and customer
     relationships to develop cost-effective and implementable intelligent
     products for the local access network. The Company is committed to
     developing products that are compatible with existing equipment and
     technologies, thereby enabling open architecture network infrastructures.
     Westell intends to continue to develop products in its core business, such
     as SmartLink, which enhance the efficiency of high speed transmission over
     copper wire, and QuadJack, which is one of the Company's first fiber optic
     products.
 
          Expand International Presence. The Company devotes significant
     resources to expanding its international business. Many of Westell's
     products, including its ADSL and HDSL systems, support E-1 standards, the
     predominant standard for digital transmission outside of North America.
     Westell has offices in Canada, England and Hong Kong and a distribution and
     service network that supports customers in more than 40 countries. The
     Company intends to continue to expand its international distribution
     arrangements and strategic relationships in an effort to increase its
     international presence.
 
          Commitment to Product Quality, Customer Service and Low-Cost
     Manufacturing. The Company benefits from a strong reputation for providing
     quality products and responsive service. Westell works closely with
     customers to provide technical consulting, maintenance and research
     assistance. Westell's continuous quality improvement is demonstrated by the
     achievement of the British Accreditation Board for Telecommunications
     safety and quality certification, Bellcore's Customer Supplier Quality
     Program ("CSQP") certification and the ISO 9001 registration of its
     domestic operations. The Company believes that its commitment to product
     quality and customer service will enhance its efforts to reduce production
     cycle times and product costs.
 
PRODUCTS
 
     The Company offers a broad range of products that facilitate the
transmission of high speed digital and analog data between a telco's central
office and end-user customers. These products can be categorized into three
groups: (i) products based on DSL technologies, including ADSL and HDSL systems
("DSL products"), (ii) Digital Signal Hierarchy Level 1 based products, which
are used by telcos to enable high speed digital T-1 transmission at
approximately 1.5 Mbps and E-1 transmission at approximately 2.0 Mbps ("DS1
products"), and (iii) Digital Signal Hierarchy Level 0 based products, which are
used by telcos to deliver digital services at speeds ranging from approximately
2.4 to 64 Kbps and analog services over a 4 Kilohertz bandwidth ("DS0
products").
 
     The prices for the products within each of the product groups of the
Company vary based upon volume, customer specifications and other criteria and
are subject to change due to competition among telecommunications manufacturers.
The Company's DSL products command higher average sales prices than its DS0 and
 
                                       28

     DSL Products. The Company is a leading developer and provider of DSL
products and transmission systems that utilize emerging ADSL technology. DSL
technology is also used for HDSL and SDSL products. Products based upon ADSL
technology can be used by telcos to provide interactive multimedia services,
including data and video dialtone applications, while simultaneously providing
traditional telephone services over existing copper wire. Products based upon
ADSL technology enable telcos to deliver these interactive multimedia services
more quickly and cost-effectively than deploying broadband fiber networks in the
"last mile" of the local access network. The Company's revenues from HDSL
products to date have not been significant.
 
     The following table sets forth a representative list of the Company's
current DSL products and their applications:

     ADSL technology permits the transmission of three communication streams of
varying speeds over existing copper wire. The non-repeatered transmission
distances of current ADSL systems vary based upon the data rate, with a maximum
distance of 18,000 feet. The first communication stream provides a one way high
speed digital data transmission from a server, such as may be found on the
Internet or in a stored video program network, to an end user. The second
communication stream provides medium speed bi-directional digital data
transmission to and from the end user which enables the end user to respond and
interact with the incoming high speed data stream. The third communication
stream provides traditional analog voice transmission capabilities permitting
simultaneous telephone service.
 
     Westell's FlexCAP ADSL system currently consists of (i) a high speed
uni-directional digital data communication stream at rates up to 1.5 or 2.0
Mbps, (ii) a bi-directional control and digital data communication stream at
rates up to 64 Kbps and (iii) a traditional analog telephone service line. This
ADSL system can support high speed data applications, such as high speed
Internet access and remote LAN access, and video-on-demand services over
existing telephone lines. In late calendar year 1996, Westell plans to introduce
rate adaptive FlexCAP ADSL systems using RADSL technology which will increase
the bi-directional capacity to up to 384 Kbps.
 
     The Company also markets other products that facilitate telcos'
incorporation of ADSL technology into their network infrastructures. Westell has
exclusive worldwide distribution rights to market AccessVision, an open systems
standards-based software management system that monitors and controls ADSL
equipment and
 
                                       29
<PAGE>   33
 
the interactive services transmitted through ADSL technology, which was
developed by Atlantech Technologies, Ltd. Westell's exclusive distribution
rights to AccessVision expire in December 2001.
 
     Currently over 30 telcos have purchased the Company's ADSL systems to
conduct technical and marketing trials for new interactive multimedia
applications. Bell Atlantic and British Telecom are in the process of connecting
over 2,000 customers to Westell's FlexCAP ADSL systems. Telecom Italia has
connected a total of 1,000 customers to Westell's FlexCAP ADSL systems in Rome
and Milan. ADSL applications in these trials include interactive
video-on-demand, music-on-demand, catalog shopping, financial services,
games-on-demand, television-on-demand and long distance learning services.
Internationally, Westell's ADSL systems have been purchased by telephone
administrations in Australia, Belgium, Canada, Hong Kong, Italy, Norway,
Singapore, South Korea, Spain, Switzerland and the United Kingdom.
 
     The Company's HDSL systems eliminate the need for telcos to condition the
copper wire and to install line repeaters for distances of up to 12,000 feet.
Westell's HDSL systems also contain performance and monitoring functions with
remote accessibility that may supplant the need for repeaters and NIUs. Westell
currently sells its HDSL systems to the federal government and markets its
InterAccess HDSL systems outside the U.S.
 
     DS1 Products. Westell's DS1 products provide telcos with cost-effective
solutions to transport, maintain and improve the reliability of T-1 services
over copper and fiber lines in the local access network.

</TABLE>
 
     Many of the Company's DS1 products, such as its NIUs, smart line repeaters,
office repeaters and T-1 maintenance service switches, function to monitor and
control the quality of digital transmission over copper wire. The Company's NIU
products allow telcos to monitor transmission conditions and to detect
performance problems in circuits from remote locations. All of the RBOCs and GTE
have purchased the Company's NIUs. Westell also developed and co-patented with
Ameritech a second generation NIU known as NIU-PM which monitors and stores
information for seven days so that telcos can study and detect any irregular
operations and performance of a line over time. The Company customizes its NIU
products to meet customers' particular needs. Sales of NIU products represented
45.5% of the Company's revenues in fiscal 1996.
 
     The Company's SmartLink Automatic Protection Switch system ("APS") monitors
up to eight customer T-1 channels and allows telcos to provide uninterrupted
service in the event of a fault of any channel. Once the APS detects a fault in
one channel, it automatically places that signal on a protection channel and
generates a notification alarm at the telco's central office, thereby
significantly reducing network downtime and costly data interruption. APS is
currently being deployed by two RBOCs and is in field trials with an additional
RBOC.

     Westell's QuadJack product is specifically designed to provide transmission
for one to four customer T-1 signals over fiber lines, which results in a
cost-effective means of providing T-1 services to small business customers who
typically do not require the standard 28 or more T-1 lines that fiber-based
transmission delivers to an end user.
 
     DS0 Products. Westell's DS0 products are used by telcos to deliver digital
and analog service across copper wire in the local access network at speeds
ranging from approximately 2.4 to 64 Kbps for digital transmission or 4
Kilohertz for analog transmission.

</TABLE>
 
     In some circumstances, analog data lines are the only practical way to add
a terminal to an existing analog data network. Consequently, analog transmission
is often the most economical, most easily installed or the only service
available in certain locations. Westell's DST unit provides the interface
between analog transmission and an end user's modem. The Company's other DS0
products include voice frequency channel units and mountings, which are used to
provide dedicated analog data lines, smart repeaters, which boost analog
signals, and other products which incorporate performance testing and monitoring
functions designed to improve the quality of analog transmission over copper
wire.
 
RESEARCH AND PRODUCT DEVELOPMENT
 
     The Company believes that its future success depends on its ability to
maintain its technological leadership through enhancements of its existing
products and development of new products that meet customer needs. Westell works
closely with its current and potential customers as part of the product
development process. The Company regularly customizes products to address
particular customer product needs. For the fiscal years ended March 31, 1995 and
1996, the Company recognized income of $800,000 and $2.6 million, respectively,
for customer sponsored research and development. Research and development
expenses for fiscal 1994, 1995 and 1996 were $7.7 million, $10.8 million and
$12.6 million, respectively. To date, all research and development costs have
been charged to operating expense as incurred. From time to time, development
programs are conducted by other firms under contract with the Company, and
related costs are also charged to operations as incurred.

</TABLE>
 
     To provide a more efficient transport of individual DSL facilities over
telephone networks, Westell is developing its SuperVision access multiplexer.
This SuperVision system will aggregate many DSL systems into a single high speed
optical link thereby facilitating the connection between copper wire digital
transmission used in the local access network and the optical fiber transmission
in the network "backbone." In addition, the Company recently announced the
development of its FlexVision ADSL system that is expected to provide up to 6.0
Mbps of uni-directional bandwidth supporting multiple simultaneous
video-on-demand channels of information. Westell's current ADSL systems and its
FlexVision system under development are based on CAP technology. Westell is also
developing its EnVision system, which will utilize DMT technology instead of CAP
technology and is expected to provide up to 8.0 Mbps of downstream data and 640
Kbps of bi-directional data transmission as well as traditional telephone
service.
 
     Westell is also focusing on defining products using next generation DSL
technologies such as RADSL and SDSL. RADSL will allow telcos to automatically
adjust the digital transmission rate based upon the quality of the copper
telephone wire and the transmission distance. This rate adaptability allows
telcos to maximize the digital capacity of copper wire and facilitates
installation of ADSL systems, thereby increasing the utilization of poor quality
copper telephone wires which traditionally have required extensive installation
and monitoring. Unlike HDSL, SDSL will enable the transmission of both a high
speed bi-directional digital data communication stream as well as analog
telephone service over a single pair of copper wires. SDSL is expected to reduce
telcos' costs and allow high speed bi-directional services to be introduced to
end users.
 
     The Company currently anticipates that it will introduce the products
listed in the above table in late calendar year 1996 and calendar year 1997.
However, there can be no assurance that the Company will be able to introduce
such products as planned, and the failure of the Company to do so would have a
material adverse effect on the Company's business and results of operations. In
addition, there can be no assurance that the Company's future development
efforts will result in commercially successful products or that the Company's
products will not be rendered obsolete by changing technology, new industry
standards or new product announcements by competitors.

     The Company's product development programs are carried out by engineers and
engineering support personnel based in Aurora, Illinois and Cambridge, England.
The Company's domestic engineering is conducted in accordance with ISO 9001,
which is the international standard for quality management systems for design,
manufacturing and service. The Company's research and development personnel are
organized into product development teams. Each product development team is
generally responsible for sustaining technical support of existing products,
decreasing manufacturing costs, conceiving new products in cooperation with
other groups within the Company and adapting standard products or technology to
meet new customer needs. In particular, each product development team is charged
with implementing the Company's engineering strategy of reducing product costs
for each succeeding generation of the Company's products in an effort to be a
low cost, high quality provider, without compromising functionality or
serviceability. The Company believes that the key to this strategy is choosing
an initial architecture for each product that enables engineering innovations to
result in future cost reductions. Successful execution of this strategy also
requires that the Company continue to attract and recruit highly qualified
engineers.
 
CUSTOMERS
 
     The Company's principal customers historically have been U.S. telcos. Since
fiscal 1993, the Company has also marketed its products internationally. The
Company's customers include all seven RBOCs, GTE, British Telecom and Telecom
Italia. In addition, Westell sells products to several other entities, including
public telephone administrations located outside the U.S., independent domestic
local exchange carriers, competitive access providers, interexchange carriers
and the U.S. federal government. International revenues represented
approximately $226,000, $3.7 million and $19.8 million of the Company's revenues
in fiscal 1994, 1995 and 1996, respectively, accounting for 0.4%, 5.0% and 23.8%
of the Company's revenues in such periods.

of the Company's revenues in fiscal 1994, 1995 and 1996, respectively. The
Company's future success will depend significantly upon the timeliness and size
of future purchase orders from the RBOCs, the product requirements of the RBOCs,
the success of the RBOCs' services that use the Company's products and the
financial and operating success of these providers. Sales to Ameritech, British
Telecom and U.S. West accounted for 12.0%, 11.1% and 10.4% of the Company's
revenues in fiscal 1996, respectively.
 
MARKETING, SALES AND DISTRIBUTION
 
     The Company sells its products in the U.S. principally through its domestic
field sales organization. The Company markets its products internationally in
over 40 countries under various distribution arrangements that include OEM
agreements, technology licenses and distributors supported by partners and
internationally based sales personnel. The Company's field sales organizations
and distributors receive support from internal
 
                                       33
<PAGE>   37
 
marketing, sales and customer support groups. As of March 31, 1996, the
Company's marketing, sales and distribution programs were conducted by 141
employees.
 
     The Company's international operations are based in Tampa, Florida and are
also conducted through business operations in Ottawa, Canada, Cambridge,
England, Hong Kong and Singapore, and a distribution and service network that
supports customers in more than 40 countries. The Company expects to continue to
pursue international market opportunities by focusing primarily on sales of DSL
products in international markets. The Company believes that there is a greater
demand for DSL products in international markets compared to DS0 and DS1
products due to a growing demand in foreign countries for services such as data
dialtone that require high speed digital transmission.
 
     The RBOCs and the Company's other customers are significantly larger than,
and are able to exert a high degree of influence over, the Company. Prior to
selling its products to telcos, the Company must undergo lengthy approval and
purchase processes. Evaluation can take as little as a few months for products
that vary slightly from existing products in the local access network and a year
or more for products based on new technologies such as ADSL. Accordingly, the
Company is continually submitting successive generations of its current products
as well as new products to its customers for approval. The length of the
approval processes is affected by a number of factors, including the complexity
of the product involved, the priorities of the telcos, telcos' budgets and
regulatory issues affecting telcos. In addition, the requirement that telcos
obtain FCC approval for certain services prior to their implementation has in
the past delayed the approval processes.
 
     Although the telco approval processes may vary to some extent depending on
the customer and the product being evaluated, they generally are conducted as
follows:
 
     Laboratory Evaluation. The product's function and performance are tested
     against all relevant industry standards, including those established by
     Bellcore.
 
     Technical Trial. A number of telephone lines are equipped with the product
     for simulated operation in a field trial. The field trial is used to
     evaluate performance, assess ease of installation and establish
     troubleshooting procedures.
 
     Marketing Trial. Emerging products such as ADSL are tested for market
     acceptance of new services. Marketing trials usually involve a greater
     number of systems than technical trials because systems are deployed at
     several locations in the telco's network. This stage gives telcos an
     opportunity to establish procedures, train employees to install and
     maintain the new product and to obtain more feedback on the product from a
     wider range of operations personnel.
 
     Commercial Deployment. Commercial deployment usually involves substantially
     greater numbers of systems and locations than the marketing trial stage. In
     the first phase of commercial deployment, a telco initially installs the
     equipment in select locations for select applications. This phase is
     followed by general deployment involving greater numbers of systems and
     locations. General deployment does not usually mean that one supplier's
     product is purchased for all of the telcos' needs throughout the system as
     telcos often rely upon multiple suppliers to ensure that their needs can be
     met. Subsequent orders, if any, are generally placed under single or
     multi-year supply agreements that are generally not subject to minimum
     volume commitments.
 
     In most international markets, there is one major telco per country with
limited or few alternate carriers or independent telcos. Typically, these telcos
are highly regulated, government-owned agencies that have approval and purchase
processes similar to those followed by the RBOCs.
 
CUSTOMER SERVICE AND SUPPORT
 
     Westell maintains 24-hour, 7-day-a-week telephone support and provides
on-site support. The Company also provides technical consulting, research
assistance and training to its customers with respect to the installation,
operation and maintenance of its products.
 
     The Company's products are required to meet rigorous standards imposed by
its customers. Most of the Company's products carry a limited warranty ranging
from two to seven years, which generally covers defects
 
                                       34
<PAGE>   38
 
in materials or workmanship and failure to meet published specifications, but
excludes damages caused by improper use and all other express or implied
warranties. In the event there are material deficiencies or defects in the
design or manufacture of the Company's products, the affected products could be
subject to recall. For the past five fiscal years, the Company's warranty
expenses have been relatively insignificant.
 
     The Company has supply contracts with most of its major customers. These
contracts typically do not establish minimum purchase commitments, and they may
require the Company to accept returns of products or indemnify such customers
against certain liabilities arising out of the use of the Company's products.
Although, to date, the Company has not experienced any significant product
returns or indemnification claims under these contracts, any such claims or
returns could have a material adverse effect on the Company's business and
results of operations. While the Company maintains a comprehensive quality
control program, there can be no assurance that the Company's products will not
suffer from defects or other deficiencies or that the Company will not
experience a material product recall in the future. Complex products such as
those offered by the Company may contain undetected errors or failures when
first introduced or as new versions are released. Any product recall as a result
of such errors or failures, and the associated negative publicity, could result
in the loss of or delay in market acceptance of the Company's products and have
a material adverse effect on the Company's business and results of operations.
The Company's standard limited warranty for ADSL products ranges from two to
five years. Since the Company's ADSL products are new, with limited time in
service, the Company cannot predict the level of warranty claims that it will
experience for these products. Despite testing by the Company and its customers,
there can be no assurance that existing or future products based on ADSL or
other technologies will not contain undetected errors or failures when first
introduced or as new versions are released. Such errors or failures could result
in warranty returns in excess of those historically experienced by the Company
and have a material adverse effect on the Company's business and results of
operations.
 
MANUFACTURING
 
     The Company purchases parts and components for its products from a number
of suppliers through a worldwide sourcing program. Certain key components, such
as integrated circuits and other electronic components, used in the Company's
products are currently available from only one source or a limited number of
suppliers. For instance, the Company currently depends on a division of Lucent
Technologies (formerly known as AT&T Microelectronics) to provide critical
integrated circuits used in the Company's ADSL products. In addition, certain
electronic components are currently in short supply and are provided on an
allocation basis to the Company and other users, based upon past usage. There
can be no assurance that the Company will be able to continue to obtain
sufficient quantities of integrated circuits or other electronic components as
required, or that such components, if obtained, will be available to the Company
on commercially reasonable terms. The Company purchases integrated circuits from
Lucent Technologies on a purchase order basis and does not have any formal
supply arrangements with Lucent Technologies. The Company anticipates that
integrated circuit production capacity and availability of certain electronic
components of its suppliers may be insufficient to meet demand for such
components in the future. Integrated circuits and electronic components are key
components in all of the Company's products and are fundamental to the Company's
business strategy of developing new and succeeding generations of products at
reduced unit costs without compromising functionality or serviceability. In the
past, however, the Company has experienced delays in the receipt of certain of
its key components, such as integrated circuits, which have resulted in delays
in related product deliveries. There can be no assurance that delays in key
components or product deliveries will not occur in the future due to shortages
resulting from the limited number of suppliers, the financial or other
difficulties of such suppliers or the possible limitations in integrated circuit
production capacity or electronic component availability because of significant
worldwide demand for these components. The inability to obtain sufficient key
components or to develop alternative sources for such components, if and as
required in the future, could result in delays or reductions in product
shipments, which in turn could have a material adverse effect on the Company's
customer relationships and its business and results of operations.
 
     The Company currently manufactures most of its products internally while
relying on a few subcontractors in the U.S. and the United Kingdom for various
assemblies. As part of its strategic plan to meet the
 
                                       35
<PAGE>   39
 
potential worldwide demand for its ADSL systems, however, the Company currently
is in the process of developing the manufacturing capabilities necessary to
supply and support large volumes of ADSL systems and in the future may become
increasingly dependent on subcontractors. The Company has entered into
discussions to establish subcontracting relationships for the assembly of its
ADSL systems. A reliance on third-party subcontractors involves several risks,
including the potential absence of adequate capacity and reduced control over
product quality, delivery schedules, manufacturing yields and costs. Although
the Company believes that alternative subcontractors or sources could be
developed if necessary, the use of subcontractors could result in material
delays or interruption of supply as a consequence of required re-tooling,
retraining and other activities related to establishing and developing a new
subcontractor or supplier relationship. Any material delays or difficulties in
connection with increased manufacturing production or the use of subcontractors
could have a material adverse effect on the Company's business and results of
operations. There can be no assurance that the Company will be successful in
increasing its manufacturing capacity in a timely and cost-effective manner or
that the possible transition to subcontracting will not materially adversely
affect the Company's business and results of operations.
 
     A substantial portion of the Company's shipments in any fiscal period
relate to orders for certain products received in that period. Further, a
significant percentage of orders, such as NIUs, require delivery within 48
hours. To meet this demand, the Company maintains raw materials inventory and
limited finished goods inventory at its manufacturing facility. In addition, the
Company maintains some finished goods inventory at the customer's site pursuant
to an agreement that the customer will eventually purchase such inventory. Final
testing and shipment of products to customers occurs in the Company's Oswego,
Illinois facilities. The Company's domestic facilities are certified pursuant to
ISO 9001.
 
     The Company's backlog for its DS1 and DS0 products at March 31, 1996 was
$1.9 million. The Company believes that because a substantial portion of
customer orders for DS1 and DS0 products are filled within the quarter of
receipt, the Company's backlog is not a meaningful indicator of actual revenues
for these products for any succeeding period. In general, customers purchasing
DSL products may reschedule orders without penalty to the customer. As a result,
the quantities of the Company's products to be delivered and their delivery
schedules may be revised by customers to reflect changes in their DSL product
needs. Since backlog of DSL products can be rescheduled without penalty, the
Company does not believe that its backlog of DSL products is a meaningful
indicator of future revenues from DSL products.
 
COMPETITION
 
     The markets for the Company's products are intensely competitive and the
Company expects competition to increase in the future, especially in the
emerging ADSL market. Westell's principal competitors in the DS0 market are
Adtran, Inc., Tellabs, Inc. and Teltrend, Inc. Westell's principal competitors
in the DS1 market are ADC Telecommunications Inc., PairGain Technologies, Inc.
and Teltrend, Inc. The Company's current competitors in the ADSL market include
Alcatel Network Systems, Amati Communications Corp., AT&T Paradyne, ECI Telecom,
Inc., Ericsson, LG Information and Communications, Ltd., Lucent Technologies,
PairGain Technologies, Inc., Orckit Communications, Ltd. and Performance Telecom
Corp. The Company expects competition in the ADSL market in the near future from
numerous other companies. In addition, the Telecommunications Act which was
signed into law on February 8, 1996, permits the RBOCs to engage in
manufacturing activities after the FCC authorizes an RBOC to provide long
distance services within its service territory. An RBOC must first meet specific
statutory and regulatory tests demonstrating that its monopoly market for local
exchange services is open to competition before it will be permitted to enter
the long distance market. When these tests are met, an RBOC will be permitted to
engage in manufacturing activities. Therefore, RBOCs, which are the Company's
largest customers, may potentially become the Company's competitors as well.
Many of the Company's competitors and potential competitors have greater
financial, technological, manufacturing, marketing and human resources than the
Company. Any increase in competition could reduce the Company's gross margin,
require increased spending by the Company on research and development and sales
and marketing, and otherwise materially adversely affect the Company's business
and results of operations.

     Products that increase the efficiency of digital transmission over copper
wire face competition from fiber, wireless, cable modems and other products
delivering broadband digital transmission. Many telcos have adopted policies
that favor the deployment of fiber. To the extent that telcos choose to install
fiber and other transmission media between the central office and the end user,
the Company expects that demand for its copper wire-based products will decline.
Telcos face competition from cable operators, new local access providers and
wireless service providers that are capable of providing high speed digital
transmission to end users. To the extent telcos decide not to aggressively
respond to this competition and fail to offer high speed digital transmission,
the overall demand for ADSL products could decline. In addition, the deployment
of certain products and technologies for copper wire may also reduce the demand
for the types of products currently manufactured by the Company. Specifically,
the deployment of HDSL in the U.S., which reduces telcos' need for T-1 repeaters
and NIUs, may result in a decrease in demand for Westell's DS1-based products.
Further, the Company believes that the domestic market for many of its DS0-based
products is decreasing, and will likely continue to decrease, as high capacity
digital transmission becomes less expensive and more widely deployed.
 
TELECONFERENCE SERVICES
 
     Conference Plus provides operator-assisted and automatic teleconferencing
services to customers throughout the U.S. The Company manages its
teleconferencing services through its operations center located in Schaumburg,
Illinois. Teleconferencing services allow organizations and individuals to
collect and disseminate information faster, more accurately and without the
associated costs of face-to-face meetings. The Company's strategy in this market
is to apply its expertise as a telecommunications products manufacturer to
provide cost-effective and quality teleconferencing services to satisfy the
growing customer demand for these services. Conference Plus was started by the
Company in October 1988, and generated $5.4 million, $6.8 million and $7.7
million in revenues in fiscal 1994, 1995 and 1996, respectively.
 
     Competition in the teleconferencing business is intense and the Company
expects that competition will increase due to low barriers to entry and recent
entrants into the audio teleconferencing service market. Many of Conference
Plus' competitors, including AT&T, MCI Communications and Sprint Communications,
have much greater name recognition, more extensive customer service and
marketing capabilities and substantially greater financial, technological and
personnel resources than the Company. There can be no assurance that the Company
will be able to successfully compete in this market in the future or that
competitive pressures will not result in price reductions that would materially
adversely affect the Company's business and results of operations.
 
GOVERNMENT REGULATION
 
     The telecommunications industry, including most of the Company's customers,
is subject to regulation from federal and state agencies, including the FCC and
various state public utility and service commissions. While such regulation does
not affect the Company directly, the effects of such regulations on the
Company's customers may, in turn, adversely impact the Company's business and
results of operations. For example, FCC regulatory policies affecting the
availability of telco services and other terms on which telcos conduct their
business may impede the Company's penetration of certain markets. The
Telecommunications Act lifted certain restrictions on telcos' ability to provide
interactive multimedia services including video on demand. The
Telecommunications Act establishes new regulations whereby telcos may provide
various types of video services. Rules to implement these new statutory
provisions are now being considered by the FCC. While the statutory and
regulatory framework for telcos providing video products has become more
favorable, it is uncertain at this time how this will affect telcos' demand for
products based upon ADSL technology.
 
     In addition, the Telecommunications Act permits the RBOCs to engage in
manufacturing activities after the FCC authorizes an RBOC to provide long
distance services within its service territory. An RBOC must first meet specific
statutory and regulatory tests demonstrating that its monopoly market for local
exchange services is open to competition before it will be permitted to enter
the long distance market. When these tests are met, an RBOC will be permitted to
engage in manufacturing activities and the RBOCs, which are the Company's
largest customers, may become the Company's competitors as well.
 
                                       37
<PAGE>   41
 
     The Company's business and operating results may also be adversely affected
by the imposition of certain tariffs, duties and other import restrictions on
components that the Company obtains from non-domestic suppliers or by the
imposition of export restrictions on products that the Company sells
internationally. Internationally, governments of the United Kingdom, Canada,
Australia and numerous other countries actively promote and create competition
in the telecommunications industry. Changes in current or future laws or
regulations, in the U.S. or elsewhere, could materially and adversely affect the
Company's business and results of operations.
 
PROPRIETARY RIGHTS
 
     The Company's success and future revenue growth will depend, in part, on
its ability to protect trade secrets, obtain or license patents and operate
without infringing on the rights of others. Although the Company regards its
technology as proprietary, it has only one patent on such technology. The
Company expects to seek additional patents from time to time related to its
research and development activities. The Company relies on a combination of
technical leadership, trade secrets, copyright and trademark law and
nondisclosure agreements to protect its unpatented proprietary know-how. There
can be no assurance, however, that these measures will provide meaningful
protection for the Company's trade secrets or other proprietary information.
Moreover, the Company's business and results of operations may be materially
adversely affected by competitors who independently develop substantially
equivalent technology. In addition, the laws of some foreign countries do not
protect the Company's proprietary rights to the same extent as U.S. law. The
telecommunications industry is also characterized by the existence of an
increasing number of patents and frequent litigation based on allegations of
patent and other intellectual property infringement. From time to time, the
Company receives communications from third parties alleging infringement of
exclusive patent, copyright and other intellectual property rights to
technologies that are important to the Company. There can be no assurance that
third parties will not assert infringement claims against the Company in the
future, that assertions by such parties will not result in costly litigation, or
that the Company would prevail in any such litigation or be able to license any
valid and infringed patents from third parties on commercially reasonable terms.
Further, such litigation, regardless of its outcome, could result in substantial
costs to and diversion of effort by the Company. Any infringement claim or other
litigation against or by the Company could have a material adverse effect on the
Company's business and results of operations.
 
     Many of the Company's products incorporate technology developed and owned
by third parties. Consequently, the Company must rely upon third parties to
develop and introduce technologies which enhance the Company's current products
and enable the Company, in turn, to develop its own products on a timely and
cost-effective basis to meet changing customer needs and technological trends in
the telecommunications industry. Any impairment or termination of the Company's
relationship with any licensors of third-party technology would force the
Company to find other developers on a timely basis or develop its own
technology. There can be no assurance that the Company will be able to obtain
the third-party technology necessary to continue to develop and introduce new
and enhanced products, that the Company will obtain third-party technology on
commercially reasonable terms or that the Company will be able to replace third-
party technology in the event such technology becomes unavailable, obsolete or
incompatible with future versions of the Company's products. The absence of or
any significant delay in the replacement of third-party technology would have a
material adverse effect on the Company's business and results of operations.
 
     The Company's ADSL products are dependent upon a CAP DSL technology known
as GlobeSpan(TM) that the Company licenses from AT&T Paradyne. AT&T Paradyne is
currently the sole provider of this CAP DSL technology and the Company currently
would not be able to produce any of its ADSL systems without using this
technology. The AT&T License, which expires in December 2002, is nonexclusive
and this technology has been licensed to numerous manufacturers. The Company has
entered into cooperation and development agreements with other technology
suppliers who are developing alternative DSL technologies, such as DMT DSL
technology. Under one such arrangement, the Company is currently testing
prototypes of an alternative DSL technology. Consequently, in the event AT&T
Paradyne fails to renew the AT&T License, the Company believes that it will have
sufficient access to alternative sources of DSL technology prior to December
2002 so that it will be able to continue to produce ADSL systems. However, the
cancellation or failure of AT&T
 
                                       38
<PAGE>   42
 
Paradyne to renew the AT&T License would materially adversely affect the
Company's business and results of operations if other sources of DSL technology
do not become readily available on similar terms or telcos elect not to deploy
ADSL systems utilizing alternative DSL technologies, such as DMT DSL technology.
 
     In addition, AT&T Paradyne has formed a business unit that develops and
markets products competitive with the Company's products, such as ADSL. Although
this newly-formed business unit does not affect the Company's AT&T License and
is an independent unit from the business unit licensing CAP DSL technology,
there can be no assurance that the formation of this business unit will not
affect the Company's ability to license CAP DSL technology from AT&T Paradyne
after the AT&T License expires. In addition, AT&T Corporation announced that it
intends to sell AT&T Paradyne. The Company is unable to predict what effect, if
any, such a sale would have on the Company's relationship with AT&T Paradyne or
on AT&T Paradyne's licensing of its CAP DSL technology or future technology to
the Company or others. In the event that AT&T Paradyne is sold to a competitor
of the Company, the Company's ability to continue to license CAP DSL technology
after December 2002 may be adversely affected. See "Business -- Proprietary
Rights."
 
     Rapid technological evolution has resulted in the need to implement
strategic alliances with customers and technology suppliers in order to
accelerate the time to market for new products. Without such relationships and
due to the lengthy telco product approval and purchase cycles, the technology
may be obsolete by the time it is implemented. Relationships in place with
companies such as AT&T Paradyne, Analog Devices, Inc., Motorola and certain
customers enable the Company to develop products at the same time that the
Company undergoes the product approval and purchase processes for products in
development. This can result in much quicker introduction of new products while
the technology is still in demand. Westell has cooperation and development
relationships with Atlantech Technologies Ltd., a software development company
based in Scotland, Scientific Generics, an innovative technology development
company based in Cambridge, England, and Sungmi Electronics, an industry leader
in the supply of high speed switching, transmission and local access systems
based in Seoul, Korea.
 
EMPLOYEES
 
     As of March 31, 1996, the Company had 737 full-time employees in continuing
operations and 62 full-time employees in KPINS which the Company plans to
discontinue. Westell's telecommunications business had a total of 652 full-time
employees, consisting of 141 in sales, marketing, distribution and service, 138
in research and development, 343 in manufacturing and 30 in administration.
Conference Plus had a total of 85 full-time employees. None of the Company's
employees are represented by a collective bargaining agreement nor has the
Company ever experienced any work stoppage. The Company believes its
relationship with its employees is good.
 
PROPERTIES
 
     The Company leases approximately 105,000 square feet of office, development
and manufacturing space in facilities in Oswego, Illinois (75,000 square feet)
and Aurora, Illinois (34,000 square feet), both suburbs of Chicago. The current
lease for the Oswego facility expires in August 2002 but may be terminated by
the Company at any time after August 1997 upon 12 months notice. The current
lease for the Aurora facility expires in February 1998 but may be extended by
the Company for up to two additional two-year periods. The Company also leases
facilities in Schaumburg, Illinois for Conference Plus, and in Tampa, Florida
and Cambridge, England for its international operations.
 
     While the Company believes its current facilities are adequate to support
its present level of operations, it believes that it will require additional
space in the next two years to accommodate additional expansion of its business
operations. The Company estimates that its manufacturing facilities are
operating at a utilization rate of approximately 50%. In September 1995, the
Company entered into an agreement with a real estate developer forming a LLC
that is constructing a 173,000 square foot facility in Aurora, Illinois. The
Company has entered into a 15-year lease of this facility with the LLC, which
term will commence upon the substantial completion of this facility. The Company
expects to move a portion of its operations to this new facility by the
 
                                       39
<PAGE>   43
 
third quarter of fiscal 1997. The Company will have the option to purchase the
facility being developed by the LLC or sell its interest in the LLC. It is the
Company's current intent to sell this property when construction is completed,
repay any financing and lease the facility from a third party.
 
LEGAL PROCEEDINGS
 
     The Company has been involved from time to time in litigation in the normal
course of its business. In January 1995, a former officer of a Westell
subsidiary filed suit against the Company in the Superior Court of the State of
California alleging monetary damages suffered as a result of wrongful
termination and breach of contract. The Company believes the suit is without
merit and intends to contest the suit vigorously. While the outcome of this
lawsuit cannot be determined with certainty, the Company does not believe that
the resolution of this lawsuit will have a material adverse effect on the
Company or its business and results of operations. However, a judgment against
the Company of a significant amount could have a material adverse effect on the
Company's liquidity and results of operations. The Company is not a party to any
other litigation that would have a material adverse effect on the Company or its
business and results of operations.

STOCK PLANS
 
     Employee Stock Purchase Plan. The Company has reserved an aggregate of
217,950 shares of Class A Common Stock for issuance under the Company's Employee
Stock Purchase Plan (the "Purchase Plan"). The Purchase Plan is intended to
qualify under Section 423 of the Internal Revenue Code of 1986, as amended (the
"Code"), and will permit eligible employees of the Company to purchase Class A
Common Stock through payroll deductions of up to 10% (or such larger percentage
up to 25%, as the Stock Incentive Committee administering the Purchase Plan may
in the future determine) of their compensation, provided that no employee may
purchase more than $10,000 (or such larger amount, up to $25,000, as the Stock
Incentive Committee may, in the future, determine) worth of stock in any
calendar year. The Purchase Plan has four three-month offering periods, each
beginning on January 1, March 1, July 1 and September 1 of each
 
                                       44
<PAGE>   48
 
year, with the first offering period commencing on January 1, 1996. The price of
Class A Common Stock purchased under the Purchase Plan will be not less than 85%
of the fair market value of the Class A Common Stock on the date of purchase.
The Purchase Plan will be administered by the Stock Incentive Committee. The
Board will be able to amend or terminate the Purchase Plan at any time. However,
the Board will not be able to, without stockholder approval, materially increase
the number of shares of Class A Common Stock available for issuance or
materially modify the eligibility requirements for participation or the benefits
available to participants.
 
     1995 Stock Incentive Plan. The Company has reserved an aggregate of
2,688,050 shares of Class A Common Stock for issuance under the 1995 Stock
Incentive Plan (the "Stock Incentive Plan"), which may be granted to employees,
officers and non-employee directors of the Company. The maximum number of shares
that may be subject to benefits awarded to any participant in any fiscal year
will be 200,000 shares. The Stock Incentive Plan will be administered by the
Stock Incentive Committee. Members of the Committee will waive the right to
participate in the Stock Incentive Plan while serving on the Committee. The
Stock Incentive Plan will provide for awards, which may consist of Class A
Common Stock, restricted shares of Class A Common Stock ("Restricted Shares"),
nonqualified stock options and incentive stock options ("ISOs") to purchase
shares of Class A Common Stock, performance awards and stock appreciation rights
("SARs").
 
     The exercise price for options will be payable in cash. Alternatively, with
the approval of the Stock Incentive Committee, all or part of the exercise price
may be paid by surrendering shares already owned by the optionee, or by
instructing the Company to withhold shares of Class A Common Stock otherwise
issuable upon exercise of the option. The exercise price per share of Class A
Common Stock for each stock option granted under the Stock Incentive Plan may
not be less than 85% (100% in the case of an ISO) of the closing price for the
Class A Common Stock last reported on the Nasdaq National Market on the date the
stock option is granted. The market value of a share of Class A Common Stock on
the date an SAR is granted will equal the base value of such SAR. Options and
SARs to be granted under the Stock Incentive Plan must be exercised within ten
years from the date of grant and will generally vest in annual installments as
determined by the Stock Incentive Committee. In the case of any eligible
employee who owns or is deemed to own stock possessing more than 10% of the
total combined voting power of all classes of stock of the Company, the exercise
price of any ISOs granted under the Stock Incentive Plan may not be less than
110% of the fair market value of the Class A Common Stock on the date of grant,
and the exercise period may not exceed five years from the date of grant.
 
     The Board of Directors will be able to terminate or amend the Stock
Incentive Plan at any time, except that no such action generally will be able to
adversely affect any rights or obligations regarding any awards previously made
under the Stock Incentive Plan without the consent of the recipient. In
addition, no amendment may be effective without the prior approval of
stockholders, if such approval is required for the Stock Incentive Plan to
continue to comply with applicable regulations of the Securities and Exchange
Commission. In the event of any changes in the capital structure of the Company,
such as a stock dividend or split-up, the Board of Directors must make equitable
adjustments to outstanding unexercised awards and to the provisions of the Stock
Incentive Plan as it deems necessary and appropriate. If the Company becomes a
party to a merger, reorganization, liquidation or similar transaction, the Board
of Directors may make such arrangements it deems advisable regarding outstanding
awards, such as substituting new awards for outstanding awards, assuming
outstanding awards or terminating or paying for outstanding awards.
 
401(K) PLAN
 
     All employees of the Company who are at least 18 years of age and have been
employed by the Company for at least 12 consecutive months (at least 1,000 hours
of service) are eligible to participate in the Company's 401(k) Profit Sharing
Plan (the "401(k) Plan"). Participants may contribute up to the lesser of 15% of
their current compensation or the statutorily prescribed annual limit to the
401(k) Plan. Participant contributions are held and invested by the 401(k)
Plan's trustees. The 401(k) Plan currently provides that the Company will
contribute an amount not to exceed 6% of the participant's compensation for the
year. In fiscal 1996, the Company made matching contributions of approximately
$229,000. In addition, the 401(k) Plan allows the
 
                                       45
<PAGE>   49
 
Company to make discretionary profit-sharing contributions to participants. Each
participant's deferred salary contributions vest immediately, and Company
contributions vest over a period of five years. The 401(k) Plan is intended to
qualify under Section 401 of the Code so that contributions by participants to
the 401(k) Plan, and income earned on plan contributions, are not taxable to
participants until withdrawn from the 401(k) Plan.

VOTING TRUST AND STOCK TRANSFER RESTRICTION AGREEMENT
 
     All Common Stock held for the benefit of members of the Penny family and
the Simon family, which immediately following this offering represents 53.9% of
the outstanding shares of Common Stock and 78.2% of the voting power of Westell,
is held pursuant to a Voting Trust Agreement dated February 23, 1994, as
amended, and is registered in the names of Robert C. Penny III and Melvin J.
Simon, as Trustees. Under the Voting Trust, the Trustees have all rights of
stockholders, including full voting and investment power. All decisions of the
Trustees require joint approval. The beneficiaries (the "Beneficiaries") of the
Voting Trust receive all cash dividends and distributions paid on the shares
held in the Voting Trust. The Beneficiaries may not withdraw shares held in the
Voting Trust without the consent of the Trustees. In addition, members of the
Penny family may not transfer their beneficial interests in the Voting Trust
without complying with the rights of first refusal described below.
Beneficiaries representing 75% of the voting power of the shares held in the
Voting Trust may amend the Voting Trust or remove the Trustees at any time. The
Voting Trust continues until May 2015 unless earlier terminated or extended.
 
     All members of the Penny family who are Beneficiaries under the Voting
Trust are parties to a Stock Transfer Restriction Agreement with the Company
(the "Stock Transfer Restriction Agreement"). The Stock Transfer Restriction
Agreement prohibits, with limited exceptions, such Beneficiaries from
transferring any Common Stock or their beneficial interests in the Voting Trust
acquired prior to the date of this Prospectus without first offering such stock
or beneficial interests to the other members of the Penny family. In addition,
the Company's Amended Certificate of Incorporation provides that shares of Class
B Common Stock are automatically converted into shares of Class A Common Stock
if they are transferred to persons other than "permitted transferees." See
"Description of Capital Stock" and "Shares Eligible for Future Sale."

<PAGE>   52
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 43,500,000 shares
of Class A Common Stock, 25,000,000 shares of Class B Common Stock and 1,000,000
shares of Preferred Stock, each with a par value of $0.01 per share. After the
completion of this offering, 15,071,962 shares of Class A Common Stock and
21,233,020 shares of Class B Common Stock will be issued and outstanding.
 
     The following description of the capital stock of the Company and certain
provisions of the Company's Amended Certificate of Incorporation and By-laws is
a summary and is qualified in its entirety by the provisions of the Amended
Certificate of Incorporation and By-laws, which have been filed as exhibits to
the Company's Registration Statement, of which this Prospectus is a part.
 
COMMON STOCK
 
     Dividends. Holders of record of shares of Common Stock are entitled to
receive such dividends when, if and as may be declared by the Board of Directors
out of funds legally available for such purposes. No dividends may be declared
or paid on any share of any class of Common Stock, unless such dividend, at the
same rate per share, is simultaneously declared or paid on each share of the
other class of Common Stock. In the case of a stock dividend or distribution,
holders of Class A Common Stock are entitled to receive the same percentage
dividend or distribution as holders of Class B Common Stock and vice versa,
except that stock dividends and distributions shall be made in shares of Class A
Common Stock to the holders of Class A Common Stock and in shares of Class B
Common Stock to the holders of Class B Common Stock.
 
     Voting Rights. Holders of Class A Common Stock are entitled to one vote per
share and holders of Class B Common Stock are entitled to four votes per share.
Holders of shares of Common Stock will vote as a single class on all matters
submitted to a vote of stockholders except with respect to future issuances of
Class B Common Stock and as otherwise required by law. The Amended Certificate
of Incorporation provides that all issuances of Class B Common Stock must be
approved by the affirmative vote of a majority of each class of Common Stock,
voting separately as a class, except with respect to (i) payment of stock
dividends on Class B Common Stock and (ii) a stock split, reclassification or
other subdivision of the Class B Common Stock. Under Delaware law, the
affirmative vote of the holders of a majority of the outstanding shares of any
class of Common Stock is required to approve, among other things, a change in
the designations, preferences or limitations of the shares of such class of
Common Stock.
 
     Convertibility. Each share of Class B Common Stock is convertible, at the
option of its holder, into one share of Class A Common Stock at any time. The
Class A Common Stock is not convertible into Class B Common Stock. Each share of
Class B Common Stock shall automatically be converted into one share of Class A
Common Stock in the event (i) such share shall be transferred (including,
without limitation, by way of sale, assignment, exchange, gift, bequest,
appointment or otherwise) to any person or entity other than a "Permitted
Transferee" or (ii) the number of shares of Class B Common Stock outstanding at
any time is equal to or less than 10% of the total number of outstanding shares
of Class B Common Stock and Class A Common Stock. A "Permitted Transferee"
includes (i) any other holder of Class B Common Stock, (ii) any member of the
Penny family or the Simon family, (iii) Gary F. Seamans, his spouse or any of
their descendants and (iv) certain other permitted transferees.
 
     Liquidation Rights. Upon liquidation, dissolution or winding-up of the
Company, the holders of Class A Common Stock are entitled to share ratably with
the holders of Class B Common Stock in all assets available for distributions
after payment in full to creditors.
 
     Other Provisions. The holders of Common Stock are not entitled to
preemptive or subscription rights. In any merger, consolidation or business
combination, the consideration to be received per share by holders of Class A
Common Stock must be identical to that received by holders of Class B Common
Stock. No class of Common Stock may be subdivided, consolidated, reclassified or
otherwise changed unless the other class of Common Stock concurrently is
subdivided, consolidated, reclassified or otherwise changed in the same
proportion and in the same manner. All outstanding shares are, and the shares of
Class A Common Stock offered hereby will be upon issuance, validly issued, fully
paid and nonassessable.
 
                                       49
<PAGE>   53
 
PREFERRED STOCK
 
     The Board of Directors has the authority to issue up to 1,000,000 shares of
Preferred Stock in one or more series and to fix the rights, preferences,
privileges and restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption, liquidation preferences, sinking
fund terms and the number of shares constituting any series or the designation
of such series, without any further vote or action by stockholders. The issuance
of Preferred Stock could adversely affect the voting power of holders of both
classes of Common Stock and the likelihood that such holders will receive
dividend payments and payments upon liquidation and could have the effect of
delaying, deferring or preventing a change in control of the Company. The
Company has no present plan to issue any shares of Preferred Stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Amended Certificate of Incorporation contains provisions (i)
eliminating the personal liability of its directors, officers, employees and
other agents for monetary damages resulting from breaches of their fiduciary
duty to the fullest extent permitted by the law and (ii) indemnifying its
directors and officers to the fullest extent permitted by the General
Corporation Law of Delaware. These provisions in the Amended Certificate of
Incorporation do not eliminate the duty of care and, in appropriate
circumstances, equitable remedies such as an injunction or other forms of
non-monetary relief would remain available under Delaware law. Each director
will continue to be subject to liability for breach of a director's duty of
loyalty to the Company or its stockholders, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
any transaction from which the director derived an improper personal benefit and
for improper distributions to stockholders. These provisions also do not affect
a director's responsibilities under any other laws, such as the federal
securities laws or state or federal environmental laws.
 
     The Company's Amended Certificate of Incorporation and By-laws also permit
it to secure insurance on behalf of any person it is required or permitted to
indemnify for any liability arising out of his or her actions in such capacity,
regardless of whether Delaware Law would permit indemnification. The Company
maintains liability insurance for its directors and officers.
 
     At present, except for the lawsuit described in "Business -- Legal
Proceedings," there is no pending litigation or proceeding involving any
director, officer, employee or agent of the Company where indemnification will
be required or permitted and the Company is not aware of any other threatened
litigation or proceeding that might result in a claim for such indemnification.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF AMENDED CERTIFICATE OF INCORPORATION,
BY-LAWS AND DELAWARE LAW
 
     The Company's Amended Certificate of Incorporation or By-laws, as
applicable, among other things, (i) limit the right of stockholders to call
special stockholders meetings, (ii) require stockholders to follow an advance
notification procedure for certain stockholder nominations of candidates to the
Board of Directors and for new business to be conducted at stockholders
meetings, and (iii) provide that the Board of Directors, without action by the
stockholders, may issue and fix the rights and preferences of shares of
Preferred Stock. These provisions may have the effect of delaying, deferring or
preventing a change of control of the Company without further action by the
stockholders, may discourage bids for the Class A Common Stock at a premium over
the market price of the Class A Common Stock, may adversely affect the market
price of, and the voting and other rights of, the holders of the Class A Common
Stock and could have the effect of discouraging certain attempts to acquire the
Company or remove incumbent management or members of the Company's Board of
Directors even if some or a majority of the Company's stockholders deemed such
an attempt to be in their best interests.
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"). Section 203 prohibits a publicly held Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless (i) prior to such date, the board of
directors of the corporation approves either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder, (ii) upon consummation of the transaction which resulted in the
stockholder becoming
 
                                       50
<PAGE>   54
 
an interested stockholder, the interested stockholder owns at least 85% of the
outstanding voting stock (excluding certain shares held by persons who are both
directors and officers of the corporation and certain employee stock plans), or
(iii) on or after the consummation date, the business combination is approved by
the board of directors and by the affirmative vote of at least 66 2/3% of the
outstanding voting stock that is not owned by the interested stockholder. For
purposes of Section 203, a "business combination" includes, among other things,
a merger, asset sale or other transaction resulting in a financial benefit to
the interested stockholder, and an "interested stockholder" is generally a
person who, together with affiliates and associates, owns (or within three
years, owned) 15% or more of the corporation's voting stock.

     The transfer agent and registrar for the Common Stock is LaSalle National
Trust, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have outstanding
15,071,962 shares of Class A Common Stock and 21,233,020 shares of Class B
Common Stock (15,323,001 shares of Class A Common Stock and 21,136,981 shares of
Class B Common Stock if the Underwriters' over-allotment option is exercised in
full). All outstanding shares of Class A and Class B Common Stock will either be
freely tradeable in the public market or eligible for immediate public sale
subject (i) in the case of 19,552,938 shares held pursuant to the Voting Trust,
to certain rights of first refusal held by members of the Penny family, (ii) in
the case of certain shares, to the volume and manner of sale limitations imposed
by Rule 144 under the Securities Act and (iii) in the case of certain shares,
the lock-up agreements described below. The Class B Common Stock is convertible
on a share-for-share basis into Class A Common Stock and must be converted to
effect any public sale of such stock.
 
     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are aggregated) who is an affiliate of the Company or who has
beneficially owned restricted securities, which are issued and sold in reliance
upon exemptions from registration under the Securities Act, for at least two
years is entitled to sell within any three-month period a number of shares that
does not exceed the greater of 1% of the then outstanding shares of Common Stock
or the average weekly trading volume in the Common Stock during the four
calendar weeks preceding the filing of a notice of intent to sell. Sales under
Rule 144 are also subject to certain manner-of-sale provisions, notice
requirements and the availability of current public information about the
Company. However, a person who is not deemed to have been an "affiliate" of the
Company at any time during the three months preceding a sale, and who has
beneficially owned restricted securities for at least three years, would be
entitled to sell such shares under Rule 144 without regard to volume
limitations, manner-of-sale provisions, notice requirements or the availability
of current public information about the Company.
 
     The Selling Stockholders and all of the directors and executive officers of
the Company holding in the aggregate 24,957,806 shares of Common Stock upon
completion of this offering have agreed, subject to certain limited exceptions,
not to sell or offer to sell or otherwise dispose of the shares of Common Stock
currently held by them, any options or warrants to purchase any shares of Common
Stock or any securities convertible into or exchangeable for any shares of
Common Stock for a period of 90 days after the date of this Prospectus without
the prior written consent of Montgomery Securities. Montgomery Securities may,
in its sole discretion and at any time without notice, release all or any
portion of the securities subject to these lock-up agreements. In addition, the
Company has agreed that for a period of 90 days after the date of this
Prospectus it will not, without the consent of Montgomery Securities, issue,
offer, sell, grant options to purchase or otherwise dispose of any equity
securities or securities convertible into or exchangeable for equity securities
except for shares of Class A Common Stock offered hereby and shares issued
pursuant to the Purchase Plan and the Stock Incentive Plan.
 
     Robert C. Penny III and Melvin J. Simon, the Trustees under the Voting
Trust, which holds 19,552,938 shares of Class B Common Stock, or 53.9% of the
shares of Common Stock outstanding after this offering, have entered into a
Registration Rights Agreement with the Company under which the Trustees have
certain rights to require the Company to register the Class A Common Stock into
which such shares of Class B Common Stock are convertible for sale under the
Securities Act (the "Registration Rights Agreement"). The Registration Rights
Agreement grants the Trustees the right to require the Company to file three
registration statements on Form S-1 and additional registration statements on
Form S-3 covering sales of such shares. In addition, if the Company proposes to
register any of its securities for sale under the Securities Act, the Trustees
are entitled to notice of such registration and to include their shares in such
registration, subject to the right of the participating underwriters to limit
the number of shares owned by the Trustees included in such registration. All
expenses related to such registration statements, excluding underwriting
discounts, will be paid by the Company, and the Company and the Trustees have
agreed to indemnify each other against certain liabilities, including
liabilities under the Securities Act.

respect thereof.

members, if any, may engage in passive market making transactions in the Class A

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Westell Technologies, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Westell
Technologies, Inc. (a Delaware corporation) and Subsidiaries as of March 31,
1995 and 1996 and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended March 31, 1996. 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 Westell Technologies, Inc.
and Subsidiaries as of March 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
March 31, 1996, in conformity with generally accepted accounting principles.

     Disclosures About Fair Value of Financial Instruments
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instrument held by the Company:
 
          Cash, trade receivables and trade payables: the carrying amounts
     approximate fair value because of the short maturity of these items.
 
          Revolving promissory notes and installment notes payable to a bank:
     due to the floating interest rate on these obligations, the carrying
     amounts approximate fair value.
 
     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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and revenue and expenses during the period reported. Actual results
could differ from those estimates. Estimates are used when accounting for
allowance for uncollectible accounts receivable, inventory obsolescence, product
warranty, depreciation, employee benefit plans, taxes, and contingencies.

NOTE 1. SUMMARY OF ACCOUNTING POLICIES: (CONTINUED)
     Foreign Currency Translation
 
     The financial position and the results of operations of the Company's
foreign subsidiary are measured using local currency as the functional currency.
Assets and liabilities of this subsidiary are translated at the exchange rate in
effect at the end of each period. Income statement accounts are translated at
the average rate of exchange prevailing during the period. Translation
adjustments arising from differences in exchange rates from period to period are
included in the foreign currency translation adjustments account in
stockholders' equity.
 
     The Company recorded a transaction loss of $270,000 in other income
(expense) for fluctuations on foreign currency rates on accounts receivable in
the fiscal year ended March 31, 1996.
 
     Computation of Net Income (Loss) Per Share
 
     Net income (loss) per share is computed using the weighted average number
of common shares outstanding during the period. These shares have been included
in the computation of net income (loss) per share. The computations for net
income (loss) per share reflect the retroactive restatement for the 2-for-1
stock split in the form of a dividend to holders of record on May 20, 1996 and
to be effected on June 7, 1996.

     Management has not recorded a valuation allowance because it believes that
the deferred tax asset will be fully realized based on current estimates of
future taxable income, future reversals of existing taxable temporary
differences or available tax planning strategies.
 
     The Company has approximately $1.8 million in income tax credit
carryforwards and a $1.9 million net operating loss carryforward that are
available to offset taxable income in the future. The tax credit carryforwards
begin to expire in 2009 and the net operating loss carryforward expires in 2011.
 
NOTE 5. LEASE COMMITMENTS:
 
     The Company has agreements to lease a manufacturing facility and several
office facilities through 2000. In addition, the leases require the Company to
pay utilities, insurance and real estate taxes on the facilities. The current
manufacturing facility lease expires in 2002. The Company has the option to
terminate this lease in 1997 and can purchase the facility at any time at fair
market value.

     In September 1995, the Company entered into an agreement to form a limited
liability company, Westell-Meridian LLC ("LLC"), for the purpose of developing a
16.4 acre site in Aurora, Illinois into a 173,000 square foot corporate facility
to house manufacturing, engineering, sales, marketing and administration. In
connection therewith, the Company currently has a 98% ownership interest in the
LLC, which will gradually decrease to a 60% ownership interest as the other LLC
member increases its capital contribution to the LLC by contributing its
development fees for the new facility, as earned. In addition, the Company has a
reimbursement obligation with respect to an irrevocable letter of credit issued
for the Company's account in the amount of $952,000, due on or before September
30, 1996, which represents the Company's capital contribution to the LLC.
 
     In September 1995, the Company advanced the LLC $1.4 million for the
purchase of land in the form of a short-term note which bears interest at the
prime rate (8.25% at March 31, 1996). The note and accrued interest become due
and payable from proceeds of construction financing. This note has been
eliminated in consolidation as of March 31, 1996. During fiscal 1996 the LLC
began construction of the facility and as of March 31, 1996 $3.0 million of
construction costs and $1.4 million of land are included in Land and building
construction held for sale in the accompanying balance sheet. It is managements'
current intention to sell its interest in this property when construction is
completed, repay any financing and lease the facility from a third party.
 
     In addition, in September 1995, the Company entered into a 15 year lease
with the LLC for the facility being developed by the LLC. Lease payments will be
based upon construction costs and permanent financing arrangements and will be
determined upon building completion.
 
NOTE 6. CAPITAL TRANSACTIONS AND STOCK RESTRICTION AGREEMENTS:
 
     The members of the Penny family (major stockholders) have a Stock Transfer
Restriction Agreement which prohibits, with limited exceptions, such members
from transferring their Common Stock acquired prior to November 30, 1995,
without first offering such stock to the other members of the Penny family. A
total of 18,998,770 shares of Common Stock are subject to this Stock Transfer
Restriction Agreement.
 
     During fiscal 1994, common stock awards equal to 312,330 shares were
granted by the Company to certain employees. The number of restricted shares
vested at March 31, 1994, 1995 and 1996 for these stock awards and others
previously granted was 397,565; 674,724 and 740,807 shares, respectively. The
Company valued the stock awards granted during fiscal 1994 at $1.03 per share.
This valuation was based on independent appraisals done at the approximate date
of the grants. Compensation expense of $70,000, $64,000 and $68,000 was
recognized in fiscal 1994, 1995, 1996, respectively, based on the fair market
value of the shares granted. The remaining compensation expense to be recognized
is $117,000 which will be recognized through fiscal 1998 as the stock awards
vest. In addition, the Company granted additional compensation to

     On May 8, 1996, the Board of Directors authorized a two-for-one stock split
in the form of a dividend to be distributed on June 7, 1996, to stockholders of
record on May 20, 1996. All references in the financial statements to number of
shares and per share amounts of the Company's common stock have been
retroactively restated to reflect the two-for-one stock split.
 
NOTE 7. BENEFIT PLAN:
 
     The Company sponsors a 401(k) benefit plan (the "Plan") which covers
substantially all of its employees. The Plan is a salary reduction plan which
allows employees to defer up to 15% of wages subject to Internal Revenue Service
allowed limits. The Plan also allows for Company discretionary contributions.
The Company provided for discretionary and matching contributions to the Plan
totaling $260,000, $161,000 and $229,000 for fiscal 1994, 1995 and 1996,
respectively.
 
NOTE 8. SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT:

     Major telephone companies comprise a significant portion of the Company's
trade receivables. One customer represented 20.0% of the trade receivables
balance at March 31, 1995 and four customers represented 51.6% of the trade
receivables balance at March 31, 1996.
 
NOTE 9. COMMITMENTS AND CONTINGENCIES:
 
     In January 1995, a former officer of a subsidiary of the Company filed a
suit against the Company alleging damages suffered as a result of wrongful
termination and breach of contract. Management believes the suit is without
merit and intends to contest the suit vigorously. While the final outcome of
this lawsuit cannot be determined with certainty, management believes the former
officer was released for cause under the terms of an existing agreement and that
the ultimate outcome will not have a material adverse effect on the Company's
business and results of operations or its financial position.
 
NOTE 10. DISCONTINUED OPERATIONS:
 
     Effective May 1, 1994, the Company acquired the assets of Key Prestige,
Inc. ("KPI") for approximately $200,000 in cash and assumed liabilities of
approximately $190,000. The purchase price was allocated to the assets and
liabilities of KPI based on their relative fair values. Approximately $340,000
was allocated to fixed assets and $50,000 to a non-compete agreement. KPI was
merged with Information Network Systems, Inc. to

form KPINS in fiscal 1995. The acquisition, which was accounted for as a
purchase, was funded with proceeds from the revolving promissory notes described
in Note 2.
 
     In August 1995, the Board of Directors approved a plan for the disposition
of KPINS. The net losses of KPINS have been segregated in the consolidated
statements of operations as "discontinued operations." The Company intends to
sell KPINS before August 31, 1996. The components of the loss from discontinued
operations for the year ended March 31, 1996 are as follows:

     As the Company does not expect KPINS to incur operating losses between
March 31, 1996 and the anticipated date of disposal, no provision for operating
losses during the phase-out period has been made.

number of authorized shares from 14,500,000 shares of common stock to 17,400,000
shares of Class A Common Stock and 11,605,858 shares of Class B Common Stock and
created Class A Common Stock with voting rights of one vote per share and Class

rights, preferences, privileges and restrictions thereof, including dividend
rights, conversion rights, voting rights, terms of redemption, liquidation

or the designation of such series, without any further vote or action by
stockholders.

NOTE 12. STOCK PLANS: (CONTINUED)
     In October 1995, the Company adopted a stock incentive plan that permits
the issuance of Class A Common Stock, restricted shares of Class A Common Stock
and stock options to purchase Class A Common Stock, performance awards and stock
appreciation rights to selected employees, officers, consultants and non-
employee directors of the Company. Under the stock incentive plan 2,688,050
shares were authorized and 2,573,526 shares were available for future issuance

this plan in fiscal 1996. Compensation expense of $164,000 and $73,000 was
recognized in fiscal 1996 for the stock awards and the related taxes,

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under Delaware law, a corporation may indemnify any person who was or is a
party or is threatened to be made a party to an action (other than an action by
or in the right of the corporation) by reason of his service as a director or
officer of the corporation, or his service, at the corporation's request, as a
director, officer, employee or agent of another corporation or other enterprise,
against expenses (including attorneys' fees) that are actually and reasonably
incurred by him ("Expenses"), and judgments, fines and amounts paid in
settlement that are actually and reasonably incurred by him, in connection with
the defense or settlement of such action, provided that he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the
corporation's best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was unlawful.
Although Delaware law permits a corporation to indemnify any person referred to
above against Expenses in connection with the defense or settlement of an action
by or in the right of the corporation, provided that he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the corporation's
best interests, if such person has been judged liable to the corporation,
indemnification is only permitted to the extent that the Court of Chancery (or
the court in which the action was brought) determines that, despite the
adjudication of liability, such person is entitled to indemnity for such
Expenses as the court deems proper. The determination as to whether a person
seeking indemnification has met the required standard of conduct is to be made
(1) by a majority vote of a quorum of disinterested members of the board of
directors, or (2) by independent legal counsel in a written opinion, if such a
quorum does not exist or if the disinterested directors so direct, or (3) by the
stockholders. The General Corporation Law of the State of Delaware also provides
for mandatory indemnification of any director, officer, employee or agent
against Expenses to the extent such person has been successful in any proceeding
covered by the statute. In addition, the General Corporation Law of the State of
Delaware provides the general authorization of advancement of a director's or
officer's litigation expenses in lieu of requiring the authorization of such
advancement by the board of directors in specific cases, and that
indemnification and advancement of expenses provided by the statute shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement or otherwise.

     The Company's Amended and Restated Certificate of Incorporation and the
Company's Amended and Restated By-laws provide for indemnification of the
Company's directors, officers, employees and other agents to the fullest extent
not prohibited by the Delaware law.
 
     The Company maintains liability insurance for the benefit of its directors
and officers.
 
     Under the terms of the Underwriting Agreement, the Underwriters have agreed
to indemnify, under certain conditions, the Selling Stockholders, the Company,
its directors, certain of its officers and persons who control the Company
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act") against certain liabilities.

ITEM 17. UNDERTAKINGS.
 
     (a) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered hereunder, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
 
     (b) The undersigned Registrant hereby undertakes that for purposes of
determining any liability under the Securities Act, (i) the information omitted
from the form of prospectus filed as part of this Registration Statement in
reliance upon Rule 430A and contained in a form of prospectus filed by the
Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this Registration Statement as of the time it was
declared effective and (ii) each post-effective amendment that contains a form
of prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

            (a)    The other party is in material breach of any warranty, term,
                   condition or covenant of this Agreement and fails to cure
                   that breach within thirty (30) days after receiving notice
                   of that breach and the other party's intention to terminate
                   or if such breach cannot reasonably be cured within such
                   30-day period, the breaching party has not within such
                   30-day period diligently pursued a cure and then cured the
                   breach in any event within ninety (90) days after receiving
                   such notice;

            (b)    The other party is in material breach of any warranty, term,
                   condition or covenant of Section 3; or

            (c)    The other party (i) becomes insolvent; (ii) fails to pay its
                   debts or is subject to its obligations in the ordinary
                   course of business as they mature; or (iii) admits in
                   writing its insolvency or inability to pay its debts or
                   perform any voluntary or involuntary proceeding in
                   bankruptcy, liquidation, dissolution, receivership,
                   attachment or composition or general assignment for the
                   benefit of creditors; provided that if such proceeding is
                   commenced involuntarily it has not been dismissed, bonded or
                   stayed within sixty (60) days after it begins.

            (d)    The GlobeSpan Cooperative And Development Agreement between
                   Westell and Paradyne is terminated.

                          Termination will become effective under Section
                   5.1(a) automatically upon expiration of the cure period in
                   the absence of a cure, and under Section 5.1(b) and (c)
                   immediately upon the non-terminating party's receipt of a
                   notice of termination at any time after the specified event
                   or the failure of the specified proceeding to be timely

            Confidential Information as are reasonably required to allow
            Westell Licensee to complete work-in-process for PRODUCT and to
            support PRODUCT that has already been sold as of the date of
            termination of this Agreement or that will be sold as the work-in-

            termination of this Agreement, each Party will be released from all
            obligations and liabilities to the other under this Agreement
            occurring or arising after the date or such termination, except
            that any termination of this Agreement will not relieve Westell
            Licensee of its obligation under Section 3 hereof or any purchase
            order, nor will any such termination relieve Westell Licensee or
            Westell from any liability arising from any breach of this
            Agreement.  Neither party will be liable to the other for damages
            of any sort solely as a result of terminating this Agreement in
            accordance with its terms.  Termination of this Agreement will be
            without prejudice to any other right or remedy of either party.

      (a)   Survival of Westell Licensee's and Westell's Obligations.  Any
            termination by Westell pursuant to Section 5.1 of this Agreement
            shall not affect Westell Licensee's rights and obligations with
            respect to any article made or in the process of being made with
            the use of any of the GlobeSpan DSL technology prior to such
            termination.  Westell Licensee's and Westell obligations under
            Section 3, 6, 10 & 17 of the Agreement shall survive and continue
            after any termination of rights under the Agreement.

6.          GlobeSpan License Options

      This BASIC MEMBER LICENSE Agreement is for use by Westell Licensee to
      LICENSE FOR MANUFACTURE and SELL a PRODUCT based on a DSL product design
      by Westell.  Should Westell Licensee choose to independently design its
      own product within which it desires to incorporate the GlobeSpan
      technology or should the Cooperative Development Agreement between
      Westell and Paradyne be terminated, nothing in this Agreement or any
      other agreement between Westell and Westell Licensee shall operate to
      preclude Westell Licensee from obtaining a DSL product design from a
      GlobeSpan technology licensee other than Westell or an independent
      GlobeSpan technology license directly from Paradyne.

7.          Relief from Obligations.  Except for any payment hereunder neither
            party will be deemed in default of this Agreement to the extent
            that performance of its obligations or attempts to cure any breach
            are delayed or prevented by reason of any act of God, fire, natural
            disaster, accident, act of government, strikes, shortages of
            material or supplies or any other cause beyond the reasonable
            control of such party ("Force Majeure"), provided that such party
            gives the other party written notice thereof promptly and, in any
            event, within fifteen (15) days of discovery thereof and uses good
            faith efforts to so perform or cure.  In the event of such a Force
            Majeure, the time for performance or cure will be extended for a
            period equal to the duration of the Force Majeure but not in excess
            of six (6) months.

8.          Advertising And Other Promotion.  Westell Licensee agrees that the
            GlobeSpan trademark name and logo will be included in all data
            sheets and marketing collateral material which describes and/or
            references the PRODUCT or the GlobeSpan DSL transmission technology
            used in connection with Westell Licensee's DSL PRODUCT.  Westell
            Licensee agrees that it will display the GlobeSpan trademark only
            in such form or manner as will be specifically approved by Westell.
            Westell Licensee will cause to appear on all materials or
            documentation with which the GlobeSpan trademark is used, such
            legends, markings and notices as Westell may request in order to
            give appropriate notice of any trademark rights therein.

      Westell Licensee grants Westell and Paradyne permission to publicly
      announce it as a Licensee of the GlobeSpan DSL technology and to
      distribute information to include company name, type of GlobeSpan
      technology, marketing contact name, telephone and fax number to their
      prospective customers and licensees.  Other than this, without the prior
      written consent of Westell, Westell Licensee may not use any trademarks,
      service marks, trade names, logos or other commercial or product
      designations of Westell, including,

      but not limited to, in connection with any press releases, promotions,
      advertisements or exhibitions.  Westell Licensee may not make press or
      other announcements or releases relating to this Agreement and the
      transactions which are the subject of this Agreement without the prior
      written approval of Westell.

9.          Quality Control.

      Westell Licensee shall apply the GlobeSpan trademark only to PRODUCTS
      which have been manufactured in accordance with the standards of quality
      in materials, design, workmanship, use, advertising and promotion set
      forth in the control specifications which are annexed to this Agreement
      as Schedule B ("CONTROL SPECIFICATIONS").  The CONTROL SPECIFICATIONS are
      furnished in confidence pursuant to Section 3.  Westell (accompanied by
      Paradyne as requested) shall have the right at any time to conduct during
      regular business hours an examination of PRODUCTS manufactured by Westell
      Licensee (including those assembled or tested) at Westell Licensee's
      facilities to determine compliance of such PRODUCTS with the applicable
      CONTROL SPECIFICATIONS.  If at any time such PRODUCTS shall, in sole
      opinion of Westell or Paradyne, fail to conform with the standards of
      quality in materials, design, workmanship, use, advertising, and
      promotion set forth in such CONTROL SPECIFICATIONS, Westell or Paradyne
      shall notify Westell Licensee.  Upon such notification Westell Licensee
      shall promptly cease to use the GlobeSpan trademark with such PRODUCTS
      and shall neither sell nor ship such nonconforming PRODUCTS until the
      standards of quality contained in the applicable CONTROL SPECIFICATIONS
      have been met to the satisfaction of Westell and Paradyne.

      Westell Licensee agrees to furnish to the Quality Control Representative
      to be designated by Westell, samples of Westell Licensee manufactured
      PRODUCT used with the GlobeSpan trademark, as Westell may request from
      time-to-

      time, for inspections and tests to assure conformance of the PRODUCTS
      with the applicable CONTROL SPECIFICATIONS.  Upon completion of such
      inspections and tests, Westell shall return such inspected and tested
      samples, in their current condition.  The transportation cost for
      shipment of the samples to Westell and for return of the samples to
      Westell Licensee as well as the risk of loss and damage to such samples
      shall be borne by Westell Licensee.

10.         Assignment.  The rights and liabilities of the parties under this
            Agreement will bind and inure to the benefit of the parties'
            respective successors; provided that Westell Licensee may not
            assign or delegate its obligations under this Agreement, either in
            whole or in part, without the prior written consent of Westell.
            Any attempted assignment or delegation without consent will be
            void.

11.         Export.  Each party shall comply with the applicable export control
            laws and regulations of the United States of America applicable to
            the export of the PRODUCTs, components, specifications or any
            written or oral information related thereto, and technology and
            shall obtain any permits and licenses required for the export or
            disclosure of controlled products, information and/or technology.

13.         Governing Law.  This Agreement shall in all respects be governed by
            and construed under the laws of the State of Florida.

13.1        Arbitration

      Any dispute, controversy or claim arising out of or relating to this
      Agreement, or the breach, termination or validity thereof (excluding the
      right of a party to seek an injunction in a court of competent
      jurisdiction against the violation of any obligation of such party
      hereunder) if not resolved within sixty days of a party's notice to the
      other party of such dispute shall be finally settled by arbitration
      conducted in English in Chicago, Illinois, U.S.A. expeditiously in
      accordance with the rules of the United Nations Commission for
      International Trade by a sole

      arbitrator selected by mutual agreement of the parties, or in the absence
      of such agreement within thirty (30) drays after the end of the sixty day
      period, selected by the Center for Public Resources.  The arbitration
      shall be governed by the United States Arbitration Act and judgment may
      be entered by any court having jurisdiction thereof.  The arbitrator is
      not empowered to award damages in excess of compensatory damages, and
      each party hereby irrevocably waives any damages in excess of
      compensatory damages.

14.         Severability

      If any provision of this Agreement, or the application thereof, shall for
      any reason and to any extent be determined by a court of competent
      jurisdiction to be invalid or unenforceable under applicable law, the
      remaining provisions of this Agreement shall be interpreted so as best to
      reasonably effect the intent of the parties.  The parties further agree
      to replace any such invalid or unenforceable provisions with valid and
      enforceable provisions designed to achieve, to the extent possible, the
      business purposes and intent of such invalid and unenforceable
      provisions.

15.         Amendments, Modifications and Waivers

      No delay or failure by either party to exercise or enforce at any time
      any right or provision of this Agreement will be considered a waiver
      thereof or of such party's right thereafter to exercise or enforce each
      and every right and provision of this Agreement.  No single waiver will
      constitute a continuing or subsequent waiver.  No waiver, modification or
      amendment of any provision of this Agreement will be effective unless it
      is in writing and signed by the parties, but it need not be supported by
      consideration.

16.         Equitable Relief

      Because each party will have access to and become acquainted with
      confidential and proprietary information of the other, the unauthorized
      use of disclosure of which would cause irreparable harm and significant
      injury which would be difficult to ascertain and which would not be
      compensable by damages alone, each party agrees that the other party will
      have the right to enforce this Agreement and any of its provisions by
      injunction, specific performance or other equitable relief without
      prejudice to any other rights and remedies that it may have for breach of
      this Agreement.
