Broadband Business Strategy

The Company has  concentrated  its efforts on  providing  integrated  networking
solutions and uses its ATM access and multiplexing  products to construct global
data,  voice  and  video  communications  networks.  The  Company's  access  and
broadband networking products provide an advanced multiservice  architecture for
wide area networking  solutions.  

                                        3

<PAGE>

                                      
In the early 1990s,  the Company  identified  ATM  technology  as the  preferred
solution for  addressing  the need for higher  network  bandwidth to support new
data  and  multimedia  applications  such as  Internet  services,  telemedicine,
videoconferencing and distance learning. ATM, as a broadband technology, enables
the  transmission  of  voice,  video and  high-speed  data  traffic  on a single
communications  line.  By offering ATM solutions to its  customers,  the Company
believes  it has  enhanced  its  position  as a  leading  supplier  of wide area
networking and telecommunications  products. The Company's strategy of providing
integrated solutions to its customers rests upon:

    Capitalizing  on ATM  Technology.  The  Company  believes  it has a  leading
    position in the edge switch ATM switch market.  The following  entities have
    deployed  GDC's ATM cell switches in their ATM networks:  Austrian PTT, MCI,
    France Telecom,  Deutsche Telekom,  the Mayo Clinic and Burlington  Northern
    Santa Fe. Through OEMs and reseller  channels,  GDC's APEX ATM switches have
    been supplied to  Netherlands  PTT,  Telefonica de Espana  (Spain) and Telia
    (Swedish   telephone   company).   France  Telecom,   Deutsche  Telekom  and
    Netherlands PPT have each built out their  multiservice  networks to between
    150 and 250 APEX switches that provide for LAN  interconnect,  voice,  frame
    relay and Internet services.

    Providing  Cost-Effective Flexible Product Solutions.  The Company's product
    families are designed with  architectures  that scale to most network sizes,
    performance and cost  requirements.  Customers can select the products which
    are most  appropriate to their current needs and migrate to higher  capacity
    products over time.  Standardization of a network management protocol across
    product families allows the end user to utilize a single network  management
    system,  which provides  value-added  capabilities  such as extensive  alarm
    reporting,  diagnostics  and  advanced  service  restoral  options  for each
    circuit and unit of equipment in the network.

    Improving Performance Of Customer Networks.  The Company's products are 
    designed to improve network efficiency by increasing transmission speed,
    compressing and consolidating   voice,  video  and  data  communication  
    and  providing  dynamic bandwidth allocation.

    Leveraging Global Customer Base, Distribution and Support. The Company has a
    worldwide   customer   base  of   corporate   and   government   users   and
    telecommunications   carriers.   The   Company   has   global   distribution
    capabilities,  and its ability to provide international customer service and
    support is critical to customers that run mission-critical applications over
    their networks.

ATM Market

Background.  Improvements  in  microprocessor  technology  over the past several
years have significantly  changed the way users design and build  communications
networks. The explosive growth of the Internet,  increased LAN traffic,  rollout
of wide area interactive video and multimedia,  and integration of long distance
compressed voice traffic have had a significant impact on bandwidth requirements
and service  planning for wide area  networks.  There is a compelling  logic for
network  planners and managers to  consolidate  services  over a single  network
rather than using multiple,  service-specific  networks. As a result enterprises
are now implementing ATM networks.  New competitive  service providers are using
ATM to offer  business  customers  greater  economy in the cost of services  and
facilities.  All of this new direction requires advanced access products for LAN
to WAN connectivity and efficient WAN switching solutions.

                                       4


<PAGE>

WANs  present  an  additional  bottleneck  constraining  greater  deployment  of
enterprise-wide  networks.  The  underlying  WAN  architecture  of the telephone
companies is optimized for low speed, constant bit-rate voice communications. It
does  not   scale   well  to   accommodate   high-speed,   burst-oriented   data
communications  typical of a LAN. To address  this  problem,  telecommunications
carriers have deployed  fiber optic  transmission  facilities in their  networks
over the past decade and some such  companies  are now in the process of testing
and  deploying  ATM  switches  as the  platform  of  choice  for  offering  new,
value-added services to their customers.  The Company believes that the need for
more  bandwidth  in both the LAN and WAN  environments  to support  current data
processing  and networking  applications  is a key factor driving demand for ATM
products.  Increasing  numbers of applications  combining voice,  video and data
will demand even more bandwidth than current applications. The Company believes,
for example, that the Internet is the single most compelling driver of ATM-based
backbone networks.

ATM  Segments.  In the past  five  years ATM has  become a leading  transmission
technology  for  communications  networks.  Within the broader  ATM market,  the
Company has identified three distinct segments: access concentrator,  enterprise
switch  and edge  switch as  further  described  below.  Each of these  segments
requires  significant  traffic  adaptation  functions that convert  conventional
voice, video, and data formats to ATM cells.

     Access  Concentrators.  Carrier ATM services are evolving globally.  Remote
     offices,  branch  offices and medium size business  offices are expected to
     begin  subscribing  to these new service  offerings  and will  require cost
     effective  access.  As in the frame  relay  services  arena  where low cost
     access devices enabled cost efficient  services,  the Company believes this
     will occur  over the next  several  years as the  demand  for ATM  services
     increases.  Key market  requirements  include low cost adaptation of legacy
     voice and data, support for video and IP services, and manageability of the
     trunk line by both carrier and end user.

     Enterprise  Switch.  Enterprise  switches are used to  interconnect a broad
     range  of  customer  premise  equipment,   including  LAN  hubs,   routers,
     multiplexers,   PBXs  and  video   codecs,   across  a  campus  or  a  more
     geographically  dispersed  area  to  create  high-speed  backbone  networks
     linking major corporate locations.  Key market requirements include a fault
     tolerant  architecture  and  the  ability  to  support  a  broad  range  of
     interfaces  and  adaptation  capabilities  for  new  as  well  as  legacy
     technologies.

     Edge  Switch.  The  telecommunications  carrier  edge  switch is  typically
     located in the central office of a Local Exchange Carrier, an Interexchange
     Carrier, a Competitive Access Provider or a Cable TV Operator. Switches are
     used as  platforms to provide  services to a number of end user  locations.
     Common  carriers also utilize these  switches in the basements of buildings
     to offer new services to multiple customers.  As with the enterprise switch
     market,  fault  tolerance  and the  ability  to  support  a broad  range of
     interfaces  and  adaptation   capabilities  are  key  requirements  because
     carriers need maximum  flexibility.  In addition,  the unique packaging and
     environmental requirements of telecommunications carriers must be met.

GDC's Target ATM Segments.  The access concentrator,  enterprise switch and edge
switch  markets that GDC is pursuing  address the points in a network where LAN,
voice,  video and other data  applications  converge  with WANs and the greatest
bandwidth  bottlenecks  exist.  A significant  increase in compressed  voice and
video over ATM has stirred much interest in GDC's  standards-based  multiservice
solution.  GDC also believes that, at present,  these targeted  market  segments
align  with the  Company's  core ATM  competencies  developed  over the last six
years.

Broadband Products

The  Company's  broadband  line of products  includes  ATM  Switches and Network
Management  Systems.  GDC  currently  offers a family of ATM switches and access
products for both public and private  networks under the GDC APEX name. The APEX
product  line  consists of the  APEX-DV2,  the  APEX-NPX,  the  APEX-IMX and the
APEX-MAC1.

GDC introduced the APEX-MMS (Multimedia Multipoint Server), the industry's first
"any band"  Multipoint  Control Unit (MCU),  in September  1996. Part of the ATM
broadband  family,  it can  operate on any band  (narrow,  wide,  and broad) and
provide audio,  video, and data intensive  applications like  videoconferencing,
telemedicine,  and distance  education.  Wide area transport is provided via the
shared  APEX  VIP(TM)  family  of  integrated  codecs  within  the APEX  switch,
providing Motion JPEG, H.320 and MPEG-2  compression  options allowing optimized
video-provisioned services.

Switch           Specifications                      Targeted Segment

APEX-DV2         Provides up to 6.4 Gbps of          Enterprise switch for 
                 capacity and support for up to      corporate and

                 16 ports within a single enclosure. and government users.

GDC's  APEX-Prosphere  network  management suite of applications  supports GDC's
APEX  ATM  switches.   The  network  management   platform  offers  a  powerful,
object-oriented  system  employing a graphical  user  interface  for ATM network
management via the  industry-standard  Simple Network Management  Protocol.  The
APEX-Prosphere  enables a network manager to configure APEX switches,  provision
APEX circuits, build the ATM switch network and monitor that network,  including
the  capacity  and  utilization  of each ATM node and the  status  of all  other
components of the network.

Many traditional  carriers have deployed GDC APEX ATM switches as their platform
for provisioning new differentiated data communications  services.  During 1998,
some GDC APEX customers  implemented networks to provide  standards-based  voice
over ATM which offers  compression,  silence suppression and idle detection over
variable bit-rate  services.  This allows very cost efficient  provisioning  of
both  voice  and data  services.  A number  of  corporate  customers  also  have
purchased  APEX  switches.  

                                       6

<PAGE>

GDC  believes its family of APEX  switches have the following competitive 
advantages:

        Scalability,  allowing  a customer to construct  a multitiered   switch
        network   that scales in price and  performance and offers multiple 
        services over one platform
        
        Flexibility, providing the customer with comprehensive  interfaces and 
        adaptation capabilities

        Traffic management  architecture,  providing networks with traffic 
        policing, traffic shaping, traffic prioritization and buffer management
        capabilities
       
        Switched virtual circuits,  dynamically  establishing connections  on  
        an  end-to-end  basis  

        Comprehensive compressed standards-based voice and video

Selling  prices vary directly with the size and  complexity of the systems being
ordered.

Multiplexers/Internetworking  Products.  GDC's  multiplexer and  internetworking
products family includes  systems for both branch office and corporate  backbone
locations which integrate  voice,  traditional  data, video and LAN traffic over
narrowband  (56/64  Kbps) or  wideband  (fractional  T1/E1  and  T1/E1)  digital
services. By consolidating  multiple forms of traffic over a single transmission
line,  these products  significantly  decrease an end user's network costs.  For
corporate  backbone  locations,  GDC offers  the TMS 3000 which  supports a wide
range of voice,  facsimile,  LAN,  traditional data and video applications.  The
Office Communications Manager ("OCM"), a cost-effective  networking solution for
the branch office location,  operates with the TMS 3000 as part of a network and
offers the integration of voice,  LAN routing,  frame relay and traditional data
at speeds ranging from 9.6 Kbps to T1/E1.

GDC is pursuing an aggressive TDM to ATM migration strategy.  This allows GDC to
address its  existing  TDM  customer  base with an  appropriate  forward-looking
technical  evolution.  In corporate backbone  environments  requiring  broadband
speeds and services, GDC APEX ATM switches can be used. The TMS 3000 and OCM can
feed  into the APEX  switch  enabling  GDC to  offer  an  integrated  networking
solution  which  scales  from small  remote or branch  locations  into  regional
wideband backbones and ultimately into ATM-based broadband backbones.

Access Product Strategy

The recently completed reorganization resulted in the creation of a new Networks
Access Products  Division.  The objective of this  reorganization was to improve
sales, marketing,  and engineering productivity relative to the Company's access
product  line.  The new  business  unit  intends  to  leverage  the use of sales
resources   of   distributors,    value-added    resellers,    integrators   and
telecommunication  provider channels in an effort to capitalize on breadth of
sales coverage, both domestically and internationally.  The reorganization is is
also intended to serve to intensify the selling of access products which have an
inherently short selling cycle.

GDC has adjusted to shifting  priorities  in the overall  access  market.  These
priorities are governed by the accelerated growth of Internet,  Frame Relay, and
cell-based  services,  all of  which  require  increased  attention  to  network
management and  performance  quality.  GDC  accordingly  intends to focus on the
development  and sale of products  targeted  towards market growth areas.  GDC's
digital data sets,  copper loopware  equipment,  and service  monitoring  probes
combine  to form the major  product  elements  serving to meet  emerging  market
requirements.

Access Products

Digital Data Sets.  Digital data sets are used to convert and interpret  signals
from computers and  communications  equipment into a form that is acceptable for
transmission  over  telecommunications  facilities.  GDC  offers a broad  set of
narrowband  digital data sets that  operate at various  speeds up to 64 Kbps and
wideband  digital  data sets  operating  at  fractional  T1 and T1  speeds.  GDC
supplies its digital data sets to the major North American  telephone  companies
and various end users. GDC continues to enhance its digital transmission product
line by  combining  higher  transmission  speeds with  value-added  capabilities
including data compression,  concentration,  protocol  adaptation/conversion and
network management. This enables GDC to offer differentiated and, in some cases,
unique  transmission  solutions.  The SpectraComm 5000 family of network managed
CSU/DSU products is the latest generation of digital products which are targeted
at large managed digital networks.

Analog Modems.  Analog modems convert digital  computer signals to a format that
can be transmitted  over telephone lines. The market for private line modems has
been  shrinking as telephone  networks move from an analog to a digital  format.
However, with the growth of  telecommuting  and Internet  access,  the need for
analog  modems  continues to grow.  GDC offers a broad range of private line and
dial-up modems operating at all speeds up to 56 Kbps.

Another  major  factor in the  modem  market  has been the trend to build  modem
functionality directly into personal computers and other equipment.  The Company
addressed  that  market  by  licensing  its  technology  to  semiconductor  chip
manufacturers  and to equipment  manufacturers  who pay the Company license fees
for the use or sale of  specific  V.34 or V.90  patented  technology.  Early  in
fiscal 1998 the  Company  formed the  Technology  Alliance  Group  ("TAG") as an
entity to target that market and to separate  the  business  unit for  potential
sale.  The sale was  completed  in  December  1998  (see  Partnering/Divestiture
Strategy below).

Intelligent Voice Data Access Multiplexer.  The Metroplex 6000 is an intelligent
access multiplexer  designed for cost-effective  access to a variety of data and
voice services  available in wide area networks.  It is applicable to the branch
office/small office market where it provides  connectivity from the office to an
enterprise network or to public network services.

Copper  Loopware  xDSL System.  The  Universal  Access  System 7000 is a service
provisioning  multiplexer  which allows  service  providers  to deliver  digital
services over copper loop systems,  reducing both cost and service  provisioning
time. It is particularly  applicable in international  markets.  In China and in
developing countries in Latin America and the Pacific Rim, there is insufficient
copper wire installed to support the growing demand for communications services.
GDC believes it is responding  to these needs by offering the  Universal  Access
System 7000 that utilizes  transmission  technologies  like 2B1Q (Two Binary One
Quaternary) and HDSL (High speed Digital  Subscriber Line). These products offer
much  higher  transmission  speeds  while  using half of the  copper  wire pairs
normally required to provision private line services.

VITAL Network Services

In February 1997, GDC  restructured  its service  division to form an integrated
worldwide  service  organization to provide global  traditional and professional
network  services for  telecommunications  carriers,  corporate  and  government
network   customers.   Traditional   services  include   installation,   on-site
maintenance,  technical support,  logistics and product repair. The professional
services portfolio includes 

                                       8
<PAGE>

network design and performance consulting, network audits, integration services,
remote  network  management and  educational  services.  In September  1997, the
service division became a separate company of General DataComm Industries,  Inc.
under the name VITAL Network Services, LLC.

Customer  relationships and services are managed from four area offices in North
America, Mexico, United Kingdom and Singapore. Individual worldwide services are
provided by VITAL  personnel and are augmented by third-party  service  partners
when necessary.  High level VITAL technical  support engineers using centralized
simulation labs provide our field engineers and customers remote assistance from
our VITAL Technical  Assistance  Center  (V-TEC's)  located in each area office,
with North America  containing an additional global  internetworking  center. At
September  30,  1998,  VITAL had 257 persons  engaged in the  delivery of direct
customer service support worldwide.

VITAL  embarked on a strategic  decision  to convert the entire  company  from a
single  manufacturer  support  organization to one capable of servicing multiple
manufacturer's  equipment  and  technologies.  Capable of working in  integrated
networks,  VITAL is a Cisco  Authorized  Support Provider and has established an
excellent  working  relationship  with Bay/Nortel and many other  manufacturers.
VITAL is the  exclusive  authorized  service  provider for ADC Kentrox,  Eastern
Research,  Olicom,  AccessLan and Verilink.  The target market has expanded from
end users to  include  integrators,  value  added  resellers,  distributors  and
equipment manufacturers.

Recently,  VITAL purchased all of Olicom's  (router  manufacturer)  Canadian and
United States  network  service  business,  and their support  center located in
Marlborough  Massachusetts;  VITAL also hired  approximately  30 of their highly
skilled internetworking technical personnel.

Future growth is expected to be fueled by the addition of direct sales personnel
dedicated  to the channel  market and  additional  acquisitions  of  synergistic
service businesses.

Acquisition Strategy

As part of its  business  strategy,  the  Corporation  has in the past  reviewed
acquisition  opportunities,  including  those which may  complement  its product
lines,  provide access to emerging  technologies or enhance market  penetration.
GDC's VITAL Network Services  subsidiary  acquired  Olicom's service business in
October 1998. The Corporation at this time has no  understandings or commitments
to make any  acquisitions,  and there can be no assurances that any acquisitions
will be made.

Partnering/Divestiture Strategy

The  Company is  focusing  on its  primary  business  units  (Broadband  Systems
Division,  Network Access  Division and VITAL Network  Services) and is pursuing
partnering  arrangements  and  asset  sales  to  reduce  the  current  level  of
investment  in research and  development  activities  and to provide  additional
funds for operations.

On December  31, 1998  (effective  as of December  22,  1998),  the Company sold
substantially all the assets relating to its TAG division  referenced above, to
PC-Tel,  Inc. of San Jose,  California  and a PC-Tel,  Inc.  affiliate for $16.3
million.  The  assets  sold  included:  patents,   technology,  test  equipment,
development tools, furniture,  and license agreements.  At the time of the sale,
the assets had a net carrying value on the Company's books of approximately $3.0
million. The employees of the TAG division were also transferred to PC-Tel.

Marketing, Sales and Customers

The Company's  products and services are marketed  throughout the world. GDC has
just completed a major  reorganization of business operations that creates three
major operating  divisions in the form of the Broadband  Systems  Division,  the
Network  Access  Division and VITAL Network  Services.  Each of these groups now
have their own marketing,  sales and engineering components and are separated as
distinct operating business units with separate general managers.

Internationally,  GDC maintains full subsidiary operations in Canada, the United
Kingdom,  Mexico,  France,  Germany,  Russia,  Singapore,  and Brazil. Sales and
technical support offices are maintained in Sweden,  Japan, Hong Kong, China and
Argentina.  In total, the Company manages a worldwide  distribution network with
representatives in more than 60 countries.  International operations represented
approximately 50% of the Company's revenues in fiscal 1998 as compared to 52% in
fiscal 1997.  GDC's foreign  operations are subject to all the risks inherent in
international operations.

While the majority of the Corporation's  products are sold on an outright basis,
the Corporation  also leases its equipment  through a wholly owned  consolidated
subsidiary under a versatile  selection of leasing programs designed to meet the
specific needs and objectives of its customers.

The  Corporation's  order  backlog,   while  one  of  several  useful  financial
statistics,  is,  however,  a  limited  indicator  of the  Corporation's  future
revenues.  Because of normally short delivery  requirements,  the  Corporation's
sales in each quarter  primarily depend upon orders received and shipped in that
same quarter. In addition,  since product shipments are historically  heavier in
the  last  month  of  each  quarter,  quarterly  revenues  can be  adversely  or
beneficially impacted by several events, including: unforeseen delays in product
shipments; large sales that close at the end of the quarter; sales order changes
or  cancellations;  changes in product  mix;  new product  announcements  by the
Corporation or its competitors; and the capital spending trends of customers.

Industry and  geographic  area  information  is included in Note 10 of "Notes to
Consolidated  Financial  Statements."  See "Index to  Financial  Statements  and
Schedules" on page F-1 in this report.

Research, Engineering and Product Development

In order to develop and  implement new  technology in the data,  voice and video
communications  industry and to broaden the applications  for its products,  the
Corporation has significant ongoing engineering programs for product improvement
and new product  development.  At September 30, 1998, 340 employees were engaged
in research and development activities.  To expand its pool of available talent,
the Corporation conducts research and development  activities in four locations.
In addition,  the Corporation  utilizes  contractors and outside  developers for
product development.

Development for all Network Access Division  transmission products occurs in the
Technology Research Center in Middlebury, Connecticut.  Development of Broadband
Systems Division products,  including multiplexer and internetworking  products
and enhancements to the APEX-ATM switch  products, also occurs in the Technology
Research Center. The Multimedia Research Center in Montreal,  Quebec, focuses on
ATM-based video and multimedia  applications and solutions;  The Boston Research
Center in Marlborough,  Massachusetts, is currently focused on a standards-based
approach  to  Internet   Protocol   (IP)/ATM  wide  area   networks   using  the
Multiprotocol Label Switching (MPLS) standard (with APEX ATM products);  and the
Advanced Research Centre in Basildon,  England,  focuses on next-generation  ATM
hardware and software.

The  combination of research,  development  and  capitalized  software  spending
amounted to 23.0%,  25.5% and 19.4% of revenues in fiscal  1998,  1997 and 1996,
respectively.   In  order  to  support  its   commitment  to  new  products  and
technologies,  the  Corporation  expects to continue a high level of spending on
research and product and software development.

Manufacturing

GDC's  principal  assembly  plant is a  Corporation-owned,  360,000  square-foot
facility  located  in  Naugatuck,  Connecticut,  of which  approximately  45% is
currently being utilized for manufacturing (30% is used for other GDC operations
and 25% is vacant). The Corporation also outsources the manufacturing  (assembly
and test) of certain products and  subassemblies,  generally high volume circuit
boards  and  power  and  packaging  items.   Outsourced   products   represented
approximately 40% of the manufacturing  assembly during the 1998 fiscal year. In
December 1998, GDC announced that its "through-hole"  product assembly

                                       11
<PAGE>

operation will become fully outsourced.  Management estimates that this activity
represented in excess of 50% of manufacturing's  assembly activity during fiscal
1998.

GDC's Connecticut facilities are ISO 9001 certified. ISO 9001 is a comprehensive
model for quality assurance in design/development,  production, installation and
servicing.   It  was   developed   by  a  technical   committee   comprised   of
representatives  from over 90 countries under the direction of the  Geneva-based
International Organization for Standardization.

Reliance on Key Components and Subcontractors

The  Corporation's  products use certain  components,  such as  microprocessors,
memory chips and pre-formed  enclosures  that are acquired or available from one
or a limited  number of sources.  The  Corporation  has  generally  been able to
procure  adequate  supplies of these components in a timely manner from existing
sources. While most components are standard items, certain  application-specific
integrated  circuit  chips  used  in  many  of the  Corporation's  products  are
customized to the Corporation's  specifications.  All suppliers of components do
not operate under contract.  The Corporation's  inability to obtain a sufficient
quantity of  components  when  required,  or to develop  alternative  sources at
acceptable  prices  and  within a  reasonable  time,  could  result in delays or
reductions in product  shipments which could materially affect the Corporation's
operating  results in any given period.  In addition,  as referenced  above, the
Company sometimes relies on subcontractors for product production. The inability
of such  subcontractors to deliver products in a timely fashion or in accordance
with the Company's  quality  standards could materially affect the Corporation's
operating results.

Competition

Each of the segments of the  telecommunications  and  networking  industries  is
intensely competitive. Many of the Company's current and prospective competitors
have greater name recognition,  a larger installed base of networking  products,
more extensive engineering,  manufacturing,  marketing, distribution and support
capabilities and greater financial, technological and personnel resources.

Broadband  Competition:  Many of the  participants  in the networking  industry,
including,  among others,  Nortel Networks,  Cisco Systems, ADC Kentrox,  Ascend
Communications,  Siemens, FORE Systems and Newbridge Networks, have targeted the
WAN ATM market  segment.  Other  companies are expected to follow.  In addition,
traditional  suppliers of central  office  switching  equipment such as Alcatel,
Lucent  Technologies,  Fujitsu and LM Ericsson  have  already or are expected to
offer ATM-based switches for central offices.

Access  Competition:  The Company's  competition in the network access  products
marketplace includes, among others,  Pairgain,  Adtran, Paradyne, RAD, 3Com, ADC
Kentrox and Newbridge Networks.

Each competitor offers a unique solution and all are formidable competitors.
The Company  believes it can  maintain or grow its market share for both ATM and
Access  products.  However,  there can be no assurance  that the Company will be
able to attain this objective.

Patents and Related Rights

The  Corporation  presently  owns  approximately  40  domestic  patents  and has
approximately 20 additional  applications  pending after deducting those sold to
PC-Tel as part of the TAG division sale  described  

                                       12

<PAGE>

above.  In addition,  all of these patents and  applications  have been filed in
Canada;  most also have been filed in other various foreign  countries.  Most of
those filed  outside the United States have been allowed while the remainder are
pending.  The  Corporation  believes  that  certain  features  relating  to  its
equipment  for which it has obtained  patents or for which  patent  applications
have been filed are  important  to its  business,  but does not believe that its
success is dependent upon its ability to obtain and defend such patents. Because
of the extensive  patent  coverage in the data  communications  industry and the
rapid issuance of new patents,  certain equipment of the Corporation may involve
infringement of existing patents not known to the Corporation.

Employee Relations

At September 30, 1998, the Corporation  employed 1,413 persons, of whom 340 were
research and development personnel,  359 were manufacturing  personnel, 339 were
employed  in various  selling  and  marketing  activities,  257 were in customer
support services and 118 were in general and administrative activities.

In December 1998 the  Corporation  announced a  restructuring  of its operations
into autonomous business units, and associated with this action there would be a
reduction  in  workforce  of  approximately  200 persons when the plan was fully
implemented. This reduction will occur across all functional areas.

No Company  employees  are  covered by  collective  bargaining  agreements.  The
Company has never  experienced a work stoppage and considers its relations  with
its employees to be good.

time to time parties thereto as lenders (the "Lenders"),  THE CIT GROUP/BUSINESS
CREDIT, INC., as co-agent (in such capacity, the "Co-Agent") for the Lenders and
TRANSAMERICA  BUSINESS  CREDIT  CORPORATION,  as agent  (in such  capacity,  the
"Agent")  for the Lenders,  is made as of October 13, 1998 among the  Borrowers,
the undersigned Lenders and the Agent.


                              W I T N E S S E T H :


                  WHEREAS,  the  Borrowers,  the  Lenders,  the Co-Agent and the
Agent are parties to the Loan and  Security  Agreement,  dated as of October 22,
1997 (as heretofore amended, the "Loan Agreement"; capitalized terms used herein
shall have the  meanings  assigned  to such terms in the Loan  Agreement  unless
otherwise defined herein); and

                  WHEREAS, the parties hereto desire to amend the Loan Agreement
in the manner set forth herein.

                  NOW,  THEREFORE,  in  consideration  of the  foregoing and for
other good and  valuable  consideration,  the  parties  hereto  hereby  agree as
follows:


     1.  Amendment  to Loan  Agreement.  Effective  as of the date  hereof,  and
subject to the  satisfaction  of the  conditions to  effectiveness  set forth in
Section 2 hereof, the Loan Agreement is hereby amended as follows:

     (a) Section 1.1 of the Loan  Agreement  is amended by adding the  following
definition in the proper alphabetical order:

          "'Settlement Date' has the meaning specified in Section 2.3(b)(ii)."

<PAGE>

     (b) Section 2.3 of the Loan  Agreement  is amended and restated as follows:
"SECTION 2.3. Procedure for Borrowing; Settlement Procedures.

                           (a) Each borrowing shall be made on notice, given not
                  later  than  4:00  P.M.  (Chicago  time) on the  Business  Day
                  immediately  preceding the date of the proposed borrowing,  by
                  GDC to the Agent.  Each such notice of a borrowing  (a "Notice
                  of Borrowing")  shall be by telecopier,  in substantially  the
                  form of Exhibit M,  specifying  therein the requested (i) date
                  of such borrowing and (ii) aggregate amount of such borrowing.
                  The Agent may,  on behalf of the  Lenders,  disburse  funds to
                  GDC, for the benefit of the  Borrowers,  for Revolving  Credit
                  Loans  requested by GDC. Each Lender shall reimburse the Agent
                  at the  time  set  forth  in  Section  2.3(c)  for  all  funds
                  disbursed  on its  behalf  by the  Agent,  or if the  Agent so
                  requests,  each  Lender  will  remit to the Agent its pro rata
                  share of any Revolving  Credit Loan before the Agent disburses
                  the same to GDC,  for the  benefit  of the  Borrowers.  If the
                  Agent elects to require that each Lender make funds  available
                  to the Agent prior to a disbursement  by the Agent to GDC, the
                  Agent  shall  advise  each  Lender  by   telephone   (but  not
                  voicemail)  or  telecopier  of the amount of such Lender's pro
                  rata share of the  Revolving  Credit Loan  requested by GDC no
                  later than 10:00 A.M.  (Chicago  time),  on the borrowing date
                  applicable  thereto,  and such Lender shall make  available to
                  the  Agent  such  Lender's  pro rata  share of such  requested
                  Revolving  Credit Loan, in same day funds, by wire transfer to
                  the Agent's account specified in Section 2.8(a) prior to 12:00
                  Noon (Chicago time), on the borrowing date applicable thereto.

                           (b)  (i)  In  order  to  minimize  the  frequency  of
                  transfers  of  funds   between  the  Agent  and  each  Lender,
                  notwithstanding  anything to the  contrary  set forth  herein,
                  Revolving Credit Loans and payments in respect thereof will be
                  settled  among  the  Agent and the  Lenders  according  to the
                  procedures  described in this Section 2.3(b). These procedures
                  notwithstanding, each Lender's obligation to fund its pro rata
                  share of any  Revolving  Credit  Loan made by the Agent to GDC
                  will commence on the date such  Revolving  Credit Loan is made
                  by the  Agent.  Such  payments  will be  made  by such  Lender
                  without setoff, counterclaim or deduction of any kind.

                           (ii) On the first  Business Day of each week, or more
                  frequently (including daily) if the Agent so elects (each such

                                    -2-
<PAGE>

                  day being a  "Settlement  Date"),  the Agent will  advise each
                  Lender by telephone  (but not  voicemail) or telecopier of the
                  amount  of such  Lender's  pro rata  share of the  outstanding
                  principal  amount of Revolving Credit Loans as of the close of
                  business of the first Business Day immediately  preceding such
                  Settlement  Date.  In the event that payments are necessary to
                  adjust such Lender's  actual pro rata share of the outstanding
                  principal   amount  of  Revolving   Credit  Loans  as  of  any
                  Settlement Date to equal the amount of such Lender's  required
                  pro  rata  share  of  the  outstanding   principal  amount  of
                  Revolving  Credit Loans,  the party from which such payment is
                  due will pay the other, in same day funds, by wire transfer to
                  the other's  account not later than 12:00 Noon (Chicago  time)
                  on the  Business Day  immediately  following  such  Settlement
                  Date.

                           (c) Unless  the Agent  shall  have been  notified  in
                  writing  by any  Lender  prior to a  borrowing  date that such
                  Lender  will not make the  amount  that would  constitute  its
                  Revolving  Credit  Commitment  Percentage  of the borrowing on
                  such date  available  to the Agent,  the Agent may assume that
                  such Lender has made such amount available to the Agent on the
                  Business Day immediately  following the next Settlement  Date,
                  and the Agent may,  in  reliance  upon such  assumption,  make
                  available to GDC a corresponding amount. If such amount is not
                  made  available to the Agent by 12:00 Noon  (Chicago  time) on
                  such date, such Lender shall pay to the Agent,  on demand,  in
                  addition  to  such  Lender's   Revolving   Credit   Commitment
                  Percentage of such  borrowing,  an amount equal to the product
                  of (i) the daily average  Federal Funds  Effective Rate during
                  such period,  times (ii) the amount of such Lender's Revolving
                  Credit Commitment Percentage of such borrowing,  times (iii) a
                  fraction  the  numerator  of which is the  number of days that
                  elapse from and including  such date to the date on which such
                  Lender's  Revolving  Credit  Commitment   Percentage  of  such
                  borrowing shall have become immediately available to the Agent
                  and the  denominator  of which is 360.  A  certificate  of the
                  Agent  submitted  to any Lender  with  respect to any  amounts
                  owing under this  Section  2.3(c) shall be  conclusive  in the
                  absence of manifest error. If such Lender's  Revolving  Credit
                  Commitment  Percentage of such borrowing is not made available
                  to the Agent by such  Lender by 12:00 Noon  (Chicago  time) on
                  the third  Business  Day after such date,  the Agent  shall be
                  entitled  to  recover,  on demand,  from the  Borrowers,  such
                  amount with interest  thereon at the rate per annum applicable
                  to  Revolving  Credit  Loans  hereunder.  For purposes of this
                  Section 2.3(c), any amounts received by the Agent on any

                                      -3-
<PAGE>

                  Business Day after 12:00 Noon  (Chicago  time) shall be deemed
                  to be  received  by the  Agent on the  immediately  succeeding
                  Business Day."

     (c) Section 2.10 of the Loan Agreement is amended and restated as follows:

                           "SECTION 2.10.  Collection of  Receivables.  GDC, the
                  Agent and a Lockbox Bank shall enter into separate agreements,
                  each in form and substance satisfactory to the Agent (each, as
                  amended, supplemented or otherwise modified from time to time,
                  a "Lockbox  Agreement"),  each of which,  among other  things,
                  shall provide for the opening of an account  (each, a "Lockbox
                  Account") for the deposit of each Borrower's  Collections at a
                  Lockbox Bank.  Each Borrower shall promptly  direct all of its
                  account  debtors  to  send  their  remittances  to  a  lockbox
                  established  pursuant to a Lockbox Agreement.  All Collections
                  and other  amounts  received by any  Borrower  from any of its
                  account  debtors shall promptly upon receipt be deposited into
                  a  Lockbox  Account.   Upon  the  terms  and  subject  to  the
                  conditions  set forth in the Lockbox  Agreements,  all amounts
                  held in each Lockbox  Account shall be wired each Business Day
                  into an account maintained by the Agent at First National Bank
                  of Chicago.  GDC shall enter into an agreement  with the Agent
                  and a financial institution acceptable to GDC and the Agent (a
                  "Concentration  Bank") in substantially  the form of Exhibit R
                  (as amended,  supplemented or otherwise  modified from time to
                  time,  the  "Concentration  Account  Agreement").  All amounts
                  received by a Borrower from any source (except for Collections
                  and any other amounts received by any Borrower from any of its
                  account debtors) shall promptly upon receipt be deposited into
                  an account (the  "Concentration  Account")  maintained  by the
                  Agent at a  Concentration  Bank. Upon and subject to the terms
                  and subject to the conditions  set forth in the  Concentration
                  Account  Agreement,  all  amounts  held  in the  Concentration
                  Account shall be transferred each Business Day into an account
                  maintained by the Agent at First National Bank of Chicago. The
                  Agent will credit all such payments to the Borrower's account,
                  conditional upon final  collection;  credit will be given only
                  for cleared funds received prior to 12:00 Noon,  Chicago time,
                  by the Agent at its account at First  National Bank of Chicago
                  (Account  #51-011-90),  or such  other  bank as the  Agent may
                  designate; provided, however, that for purposes of calculating
                  interest  due to the Agent  for the  benefit  of the  Lenders,
                  credit will be given to  collections  one  Business  Day after
                  receipt of cleared funds. In all cases, the Loan Account will

                                      -4-

                  be  credited  only with the net amounts  actually  received in
                  payment of Receivables."

     (d)  Section  7.1(k)(iv)  of the Loan  Agreement  is  amended  by  deleting
"commencing  at least two weeks  prior to the date on which the first  Revolving
Credit Loan is made" and substituting therefor "upon the request of the Agent".

                  2.       Conditions to Effectiveness.

                           (a)      This Amendment (other than Section 1(c))

Amendment,  duly  executed by the  Borrowers  and the Required  Lenders and duly

2(a) and  upon  the  Agent's  receipt  of  amendments  to the  existing  Lockbox
Agreements,  duly  executed by GDC and the Lockbox Bank party  thereto,  in each
case in form and substance satisfactory to the Agent.

                  3. Authorization by Lenders.  Effective as of the date hereof,
each of the undersigned  Lenders hereby  authorizes the Agent (on behalf of such
Lender)  to enter into one or more new  Concentration  Account  Agreements,  new
Lockbox  Agreements  and  amendments  to the  existing  Lockbox  Agreements  and
Concentration  Account Agreements to carry out the purpose and intent of Section
1(c) and containing such other terms as the Agent  determines to be necessary or
desirable.

                  4.  Covenant  Regarding  Mexican  Stock  Pledge.  On or before

further  documents and  instruments as the Agent may determine in its reasonable
discretion  to be necessary or desirable to perfect and protect the Liens of the
Agent (and the priority status thereof) on the Collateral  granted in accordance
with Section 2(a)(ii).

                  5.       Representations and Warranties of the Borrowers.
Each of the Borrowers represents and warrants as follows:

                           (a)      Since June 30, 1998, there has occurred no
development,  event or change  that has had or could  reasonably  be expected to

Agreement.

                           (b)      No Default or Event of Default has occurred
and is continuing.

                           (c)      The representations and warranties of such

warranties were true and correct on and as of such earlier date).

                           (d)      This Amendment constitutes the legal, valid
and binding  obligation of such Borrower,  enforceable  against such Borrower in
accordance  with  its  terms,   except  as  enforceability  may  be  limited  by

                  6.     Expenses.  The Borrowers shall, jointly and severally,
pay for all of the reasonable  costs and expenses  incurred by the Agent and the

this Amendment shall not,  except as expressly  provided  herein,  operate as an
amendment to or waiver of any right, power or remedy of the Agent or the Lenders
under any of the Loan  documents,  or  constitute  an amendment or waiver of any
provision of any of the Loan Documents.

                           (d)     This Amendment may be executed by the parties
hereto  individually or in  combination,  in one or more  counterparts,  each of
which shall be an original  and all of which shall  constitute  one and the same

                  NOW,  THEREFORE,  in  consideration  of the  foregoing and for

                           (c)      Section 1.1 of the Loan Agreement is amended

                           Revolving Credit Loans equal to the sum of (a) 80% of
                           the Eligible  Receivables and (b) 50% of the Eligible
                           Inventory;  provided,  that  in no  event  shall  the
                           aggregate    amount   of   Revolving   Credit   Loans
                           outstanding  at  any  time  in  respect  of  Eligible
                           Inventory  exceed  the  lesser  of  (i)  50%  of  the
                           aggregate   outstanding   principal  balance  of  all
                           Revolving Credit Loans and (ii) $7,500,000."

                           "'Designated Amount' means $5,000,000; provided that,
                           if the  principal  amount  of the Term  Loan has been
                           prepaid  by at least  $4,000,000  from  Extraordinary
                           Proceeds on or before March 31, 1999,  the Designated

                           "'Extraordinary   Proceeds'   means   cash   proceeds
                           received  by  the  Loan  Parties  from  one  or  more

                           deemed  to   constitute   the   consent  by,  or  the
                           authorization  of,  the  Lenders  to the  sale of any
                           assets."

                           before December 31, 1998 and (b)  $2,000,000,  if the
                           outstanding principal amount of the Term Loan has not

                           Extraordinary  Proceeds  on or  before  December  31,
                           1998;  provided that, if the principal  amount of the
                           Term  Loan has been  prepaid  by at least  $4,000,000
                           from  Extraordinary  Proceeds between January 1, 1999

                           (d)  Section 2.1(a) of the Loan Agreement is amended
by deleting "$25,000,000" and substituting therefor "the Revolving Credit Limit,

                           thereafter and (B) 100% of all Net Cash Proceeds that
                           do not constitute  Extraordinary Proceeds;  provided,
                           that,  so long as no Event  of  Default  exists,  the
                           amount of Loans  required  to be prepaid  pursuant to

                           (k)      Section 9.1 of the Loan Agreement is amended

or" and (ii) adding at the end of such Section the following new clause:

                           "(m)  The  Loan  Parties   shall  not  have  received
                           Extraordinary  Proceeds  of at least  $10,000,000  in

                           from November 20, 1998 to March 31, 1999."

                           (l)      Schedule 6.1(r) to the Loan Agreement is
deleted and replaced with Annex I attached hereto.

                  2.       Conditions to Effectiveness.

                           (a)      This Amendment  shall become effective upon
the Agent's receipt of (i) counterparts of this Amendment,  duly executed by the
Borrowers and the  undersigned  Lenders and duly consented to by the Guarantors,
(ii)  resolutions of the Board of Directors of each  Borrower,  certified by the
Secretary  or  Assistant  Secretary  of such  Borrower,  in form  and  substance
satisfactory  to  the  Agent,  (iii)  a  certificate  of a  Responsible  Officer
attesting  to the  matters  set  forth  in  Sections  5(a),  (b) and (c) of this
Amendment and (iv) an amendment fee of $360,000 in immediately  available  funds
for the  ratable  benefit of the  Lenders,  which fee shall be fully  earned and
nonrefundable on the effective date of this Amendment.

                  3. Conditions Subsequent.  On or before November 25, 1998, GDC
shall,  and shall cause each of its  Subsidiaries  to,  deliver to the Agent the
following,  each of which  shall be in form and  substance  satisfactory  to the
Agent (and the failure by GDC to timely  deliver or cause to be delivered any of
the following shall constitute an Event of Default):

                           (a)      An amendment to (or an amendment and
restatement of) each Term Note to reflect the changes set forth in Section 1(e)
of this Amendment; and

                           (b)      An amendment to (or an amendment and
restatement  of) each Stock  Subscription  Warrant  made by GDC in favor of each
Lender  (each,  a  "Warrant")  to provide  that the  Warrant  Price (as  defined
therein) is $3.9375 per share,  subject to adjustment in accordance with Section
5 thereof.

                  4.      Special Provisions Concerning Term Notes and Warrants.

                           (a)      Pending the satisfaction of the condition
subsequent set forth in Section 3(a) of this Amendment, the parties hereto agree
that if there is any conflict  between the terms of the Term Notes and the terms
of the Loan Agreement (as amended  hereby),  the terms of the Loan Agreement (as
amended hereby) shall control.

                           (b)      Pending the satisfaction of the condition
subsequent set forth in Section 3(b) of this Amendment, the parties hereto agree
that the  definition of "Warrant  Price" set forth in each Warrant is amended by
deleting "$10.00" and substituting "$3.9375."

                  5.       Representations and Warranties of the Borrowers.
Each of the Borrowers represents and warrants as follows:

                           (a)      Since June 30, 1998, there has occurred no
development,  event or change  that has had or could  reasonably  be expected to
have a Material  Adverse  Effect,  except as expressly set forth in the Business
Plan  most  recently  delivered  pursuant  to  Section  7.1(k)(ii)  of the  Loan
Agreement.

                           (b)      After giving effect to this Amendment, no
Default or Event of Default has occurred and is continuing.

                           (c)      The representations and warranties contained
in  Section  6.1 of the Loan  Agreement  are true and  correct  in all  material
respects on the date hereof as though made on and as of the date hereof,  except
(i) to the extent that such  representations  and  warranties  expressly  relate
solely to an earlier  date (in which case such  representations  and  warranties
were true and correct on and as of such  earlier  date) and (ii) as set forth on
Annex I attached hereto.

                           (d)      This Amendment and the other documents
delivered  or to  be  delivered  in  connection  herewith  (together  with  this
Amendment and the Loan Agreement as amended hereby,  the "Amendment  Documents")
constitute  the  legal,   valid  and  binding   obligations  of  such  Borrower,
enforceable  against such Borrower in accordance  with their  respective  terms,
except as enforceability may be limited by bankruptcy, insolvency and other laws
affecting creditors' rights generally and by general principles of equity.

                           (e)      Each Borrower has the power, authority and
legal right to execute,  deliver and perform the Amendment Documents to which it
is a party and the transactions  contemplated thereby, and has taken all actions
necessary to authorize the execution,  delivery and performance of the Amendment
Documents to which it is a party and the transactions contemplated thereby.

                           (f)      No consent of any Person, and no consent,
permit,  approval or  authorization  of,  exemption  by, notice or report to, or
registration, filing or declaration with, any Governmental Authority is required
in  connection   with  the  execution,   delivery,   performance,   validity  or
enforceability  of  this  Amendment,  the  other  Amendment  Documents  and  the
transactions contemplated hereby and thereby.

                           (g)      The execution, delivery and performance by
each Borrower of the Amendment Documents to which it is a party will not violate
any Requirement of Law or any contractual obligation of such Borrower.

                  6.       Expenses.  The Borrowers shall, jointly and
severally,  pay for all of the  reasonable  costs and  expenses  incurred by the
Agent and the Lenders in connection with the  transactions  contemplated by this
Amendment,  including,  without limitation,  the reasonable fees and expenses of
counsel to the Agent and the Lenders.

                  7.       Miscellaneous.

                           (a)      Except as expressly amended herein, all of
the terms and  provisions of the Loan Agreement and the other Loan Documents are
ratified  and  confirmed  in all  respects  and shall  remain in full  force and
effect.

                           (b)      Upon the effectiveness of this Amendment,
all references in the Loan  Documents to the Loan Agreement  shall mean the Loan
Agreement as amended by this  Amendment and all references in the Loan Agreement
to "this Agreement,"  "hereof," "herein," or similar terms, shall mean and refer
to the Loan Agreement as amended by this Amendment.

                           (c)     The execution, delivery and effectiveness of
this Amendment shall not,  except as expressly  provided  herein,  operate as an
amendment to or waiver of any right, power or remedy of the Agent or the Lenders
under any of the Loan  Documents,  or  constitute  an amendment or waiver of any
provision of any of the Loan Documents.

                           (d)    This Amendment may be executed by the parties
hereto  individually or in  combination,  in one or more  counterparts,  each of
which shall be an original  and all of which shall  constitute  one and the same
agreement.  This Amendment may be executed and delivered by telecopier  with the
same  force  and  effect  as if the same  were a fully  executed  and  delivered
original manual counterpart.

                           (e)  This Amendment shall constitute a Loan Document.

                  8.   Acknowledgement   of  Debt.   The  Loan  Parties   hereby
acknowledge  that as of November 17,  1998,  they are indebted to the Lenders in
the principal  amount of  $16,488,655.30  under the Loan  Documents plus accrued
interest, fees and expenses without defense, setoff or counterclaim.

                  9. Release.  Each Loan Party hereby releases the Agent and the
Lenders and their respective affiliates, officers, directors, agents, employees,
counsel, successors and assigns (collectively,  the "Releasee") from any and all
claims, demands, liabilities, obligations, costs and expenses any Loan Party may
now or hereafter  have against the  Releasee  arising  under or relating to this
Amendment, the Loan Agreement,  the other Loan Documents or otherwise,  from the
beginning of time to the date of this Amendment.

                  10.      GOVERNING LAW.  THE VALIDITY, INTERPRETATION AND
ENFORCEMENT  OF THIS  AMENDMENT  SHALL BE  GOVERNED  BY THE LAWS OF THE STATE OF
ILLINOIS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAW PRINCIPLES THEREOF.

                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Amendment to be duly executed and delivered by their  respective duly authorized

                     Management's Discussion and Analysis of
                  Results of Operations and Financial Condition


General Summary Discussion

The  Company's  fiscal  1998  strategy  was  to  focus  on  developing  its  ATM
(asynchronous  transfer mode) product business and bring operating expenses more
in line with  revenues.  Significant  progress was  registered  in both of these
areas  (ATM  revenues  grew over 30% and  operating  expenses  were  reduced  by
approximately $21.0 million);  however,  results overall remained unsatisfactory
due to revenue declines in older product areas, as discussed later.

The new strategy  for fiscal 1999 is to  restructure  the Company into  distinct
business units with increased operating autonomy and responsibility for business
unit operating  results.  This is an expansion of the  successful  launch of the
VITAL Network Services  subsidiary and its multi-vendor  service  initiatives in
the  telecommunications  industry. The two new business units, Broadband Systems
(ATM and  Internetworking  products) and Network Access (Access products),  will
each  have  a  general  manager  and  dedicated  marketing,  sales  and  product
development  operations.  As a result,  the  business  units  will be focused on
products,  sales  channels  and  technologies  unique  to each  unit and will be
streamlined to deliver the best product  performance and customer  satisfaction.
The formal  roll-out of this program was announced in December 1998 (see Note 15
to the "Notes to Consolidated  Financial  Statements" for further  discussion of
this restructuring activity).

Also, the Company is focusing on divesting  non-strategic assets and operations,
and on partnering  with other  companies on new product  developments  to reduce
working  capital  requirements  (see  Note  15 to  the  "Notes  to  Consolidated
Financial  Statements"  for  discussion  of a sale of a division  of the Company
which occurred subsequent to September 30, 1998).

Maintaining  adequate  financial  resources to support  operations remains a top
priority of  management.  The Company's loan and security  agreement  requires a
significant improvement in operating results in fiscal 1999 in order to maintain
compliance  with  the  agreement's   financial   covenants.   The  restructuring
initiative and division sale, both described  above,  were targeted at improving
the  Company's   financial   condition  and  maintaining   compliance  with  the
agreement's financial covenants, and management is committed to further actions,
if necessary,  to maintain  compliance  with such  financial  covenants.  Please
reference  the  "Financial  Condition and  Liquidity"  section below for further
discussion.

Results of Operations

The following table sets forth selected consolidated financial data stated as a

      -------------------------------------------------------------------------
  
The mix of revenue among the categories  remained  relatively  consistent,  with
service  representing a larger share of total revenue due to the overall decline
in  product  revenues.  Gross  margin  rates were also  relatively  consistent.

However,  a significant  change is reflected in lower operating  expense levels,
which, excluding restructuring charges, declined 6.6% as a percentage of revenue
due to the successful implementation of cost reduction initiatives.

     Decrease from prior year                  (6.5)%       (11.6)%

Fiscal 1998 revenues were $194.3 million, a decline of 6.5% from the prior year.
The  reduction,  principally  comprised  of a decline  in product  revenue,  was
related to a number of factors,  including weak economic  conditions in Asia and
product line  transitions.  In the Broadband Systems business unit, ATM products
registered  growth of over 30% (to over $50  million)  and  became  the  largest
product line component of this business unit.  However,  other broadband systems
(principally  time-division multiplexing [TDM]) products registered a decline of
35.8%,  with  most  of the  reduction  attributable  to the  turmoil  in  Asia's
financial markets; the Broadband Systems business unit registered an overall net
revenue  decline  of  6.2%.  In  the  Network  Access  business  unit,  customer
transitions to higher speed digital products did not offset  continued  declines
in lower speed  legacy  products,  resulting  in a net revenue  decline of 9.1%.
VITAL  Network  Services'  revenues  were  affected by the lower  volumes of the
Company's product sales on which services are performed.  However,  the business
unit was able to offset most of this decline with new service initiatives in the
multi-vendor area. Other revenues,  comprised of leasing, technology license fee
and contract  engineering  revenues,  declined $0.7 million,  with reductions in
leasing  and  license fee  revenue  being  partially  offset with an increase in
contract engineering revenue.

Geographically,  the revenue loss experienced in fiscal 1998 occurred  primarily
in  international  markets,   whereas  the  reduction  in  fiscal  1997  revenue
principally occurred domestically.  Domestic and international revenues amounted
to 50.3% and 49.7% of fiscal 1998 revenues,  respectively,  as compared to 48.3%
and 51.7%, respectively, for fiscal 1997.

Fiscal 1997 revenues were also impacted by a decline in demand for the Company's
legacy  analog and  low-speed  data set  products  (down  $13.2  million);  this
business declined  significantly as market  requirements moved to higher speeds.
ATM product shipments were down $3.8 million,  or 9.1%, in fiscal 1997. However,
market demand for the Company's  ATM products  began  escalating in the last two
quarters of fiscal 1997.  Other product  sales were down $4.9 million,  or 9.2%.
Service revenues were slightly lower in fiscal 1997. Other revenues  reflected a
decline of $5.2 million, or 33.7%, attributable to reductions in leasing revenue
($1.9  million,  resulting  from  weakness in the domestic  direct sales channel
market);  technology  licensing  revenues  ($1.2  million,  principally  due  to
one-time fees recorded in fiscal 1996); and lower contract  engineering  service
revenues ($2.1 million).

     As a percent of revenue                      6.1%         5.8%       4.9%

The dollar reduction in fiscal 1998 cost of revenues is largely due to the lower
product sales volumes. When measured as a percent of revenues, fiscal 1998 costs
increased 0.2 percentage points as compared to fiscal 1997. This modest increase
reflects higher  subcontract costs in the  international  segment of the service
business  (which added 0.4 percentage  points to costs) offset by slightly lower
cost of product sales.  Fiscal 1998  amortization of capitalized  software costs
increased as a percent of revenue due to the lower revenue base.

Fiscal 1997 cost of revenues  measured as a percentage of revenue,  increased by
1.7 percentage  points as compared to fiscal 1996. The increase in costs,  which
equates to $3.4  million,  is  attributable  to lower gross  margins in products
($2.2 million), services ($0.6 million) and license fees ($0.6 million). Product
margin reductions are attributable to price reductions on legacy analog products
and certain low-speed product lines.  Service margins reflect a shift of service
business from higher  margin  domestic  business to lower margin  (sub-contract)
international  business, and

                                       10
<PAGE>

license  fee  margins  reflect  lower  revenues.  Fiscal  1997  amortization  of
capitalized  software  costs,  up slightly in  dollars,  increased  by 0.9% when
measured as a percent of revenue due to a reduced revenue base.

High  technology  products sold by the Company are generally  subject to intense
sales price pressures as competition grows and sales cycles reach maturity.  The
Company  attempts  to offset the effect of such sales price  pressures  with the
negotiation of reduced material component prices,  improvements in manufacturing
costs and  efficiencies  and the  introduction of new generation  products which
generally provide higher margins.

  -----------------------------------------------------------------------------

The  Company  implemented  cost  reduction  actions in fiscal 1998 as part of an
overall  strategy  to  improve  financial  results.   Fiscal  1998  general  and
administrative  expenses were reduced $2.3 million,  or 15.3%,  from fiscal 1997
levels. Fiscal 1998 selling and marketing costs declined $9.8 million, or 13.8%,
in the year. The lower spending levels were also reflected in the 3.4% reduction
in expenses  measured as a percent of revenue,  which  occurred  despite a lower
revenue base.

Fiscal 1997  general and  administrative  costs were held to an increase of only
$143,000,  or 1.0% as compared to the prior year.  Selling and  marketing  costs
were  down  $681,000  or 0.9%,  for the same  period.  Salary  and  inflationary
increases were offset by efficiencies resulting from reorganization  initiatives
in our international subsidiary and sales operations.  However, selling, general
and  administrative  expenses  increased  as a  percentage  of revenue  due to a
reduced revenue base in fiscal 1997.

</TABLE>

Cost  reductions  were also  implemented  in the  product  development  areas by
reducing  development  activities  targeted at sustaining legacy products and by
focusing  development  resources  on  projects  considered  to have the  highest
likelihood of success. Spending in the ATM area continued at a significant rate,
representing 55% of total R&D gross spending, as compared to 54% in fiscal 1997.
The  complexity of the ATM technology  has  historically  demanded a significant
investment in research and  development  programs.  While future ATM  investment
levels,  measured in both  dollars and as a percent of revenue,  are expected to
remain  high in  relation  to other  product  lines,  the  Company  will  pursue
opportunities  to  reduce  costs  and the  unusually  high  level of  investment
required,  possibly through  partnering with other parties on joint developments
and/or divestiture of non-core product lines.

Fiscal 1998 capitalized  software costs increased despite the reduction in gross
expenditures,  as projects matured and reached technological  feasibility.  As a
result of the reduced gross  spending level and higher  capitalization  amounts,
overall net research and development expense declined 21.9% from fiscal 1997 and
represented a lesser percent of revenue.

The Company conducts research and development activities at four locations, with
the largest pool of resource in Middlebury,  Connecticut,  and remote facilities
in Boston, Montreal and England.

Interest and Other Income and Expense:

Interest  expense  increased  $3.1 million in fiscal 1998 over fiscal 1997.  The
increase is attributable to $25 million of 7 3/4% debentures issued on September
26, 1997 ($1.9  million of interest  expense) and a $15 million term loan issued
on October 22, 1997 ($1.6 million of interest  expense),  partially  offset with
reduced  interest cost associated  with  reductions in other other debt.  Fiscal
1997 net interest expense amounted to $2,823,000, up 37.6% from fiscal 1996. The
increase is attributable to interest costs associated with fiscal 1997 revolving
credit  facility  borrowings  (no such  borrowings  occurred in fiscal 1996) and
other financing costs incurred.

Other income and expense is typically  comprised  primarily of foreign  currency
gains and losses,  which are  discussed  below under  "Foreign  Currency  Risk."
However,  fiscal  1996 also  includes  a $1.0  million  gain on the sale of real
estate.

Income Taxes:

Income tax  provisions  for fiscal  1998,  1997 and 1996  amounted to  $700,000,
$400,000 and $1,200,000  respectively.  Such  provisions  principally  represent
provisions for foreign  income taxes and domestic  state taxes.  The reduced tax
provision for fiscal 1997  principally  reflects the reversal of tax contingency
provisions in foreign tax-paying jurisdictions.

The  Company  has   significant   domestic  net  operating  loss   carryforwards
(approximately  $144 million at September  30, 1998)  available to offset future
income  subject to federal  income taxes.  These net  operating  losses begin to
expire in the year 2004.

During  fiscal  1998 and  1997,  the  deferred  tax  asset  valuation  allowance
increased  by  $17.6  million  and  $15.6  million,  respectively,   principally
attributable  to the  uncertainty as to whether newly  generated  operating loss
carryforwards will be utilized prior to expiration.  Reference is made to Note 7
of the "Notes to Consolidated Financial Statements" for further discussion.

Market Risk

The  Company is exposed to various  market  risks,  including  potential  losses
arising  from  adverse  changes  in market  rates and  prices,  such as  foreign
currency  exchange and interest rates. The Company  historically has not entered
into derivatives,  forward exchange contacts or other financial  instruments for
trading, speculation or hedging purposes.

Foreign Currency Risk

The Company's foreign  subsidiaries are exposed to foreign currency  fluctuation
since they are invoicing  customers in local  currencies  while  liabilities for
product  purchases from the parent Company are transacted in U.S.  dollars.  The
impact  of  foreign  currency  fluctuations  on  these  U.S.  dollar-denominated
liabilities  are  recorded as a component  of "Other  Income and Expense" in the
Company's  consolidated  statements  of  operations  and  resulted  in  currency
exchange  losses of $400,000,  $1,038,000 and $325,000 in fiscal 1998,  1997 and
1996,  respectively.  The larger  exchange  loss in fiscal  1997 is  principally
attributable to the strength of the U.S. dollar relative to the French franc and
the German mark.

The  introduction  of the Euro as a common  currency for members of the European
Monetary Union is scheduled to take place in the Company's fiscal year 1999. The
Company has not  determined  what impact,  if any, the Euro will have on foreign
exchange  exposure.  However,  no  individual  foreign  subsidiary  comprises 10
percent or more of consolidated  revenue or assets;  most subsidiary  operations
represent  less than 5 percent of  consolidated  revenue or assets.  The Company
historically  has not entered into hedge  contracts or any form of derivative or
similar investment.

As a result of high inflation in Mexico,  the Company was required to change its
method of  translating  the financial  statements  of its Mexican  subsidiary to
reflect the designation of the U.S. dollar as the functional currency, effective
January 1,  1997.  Mexico  will cease  being  considered  a highly  inflationary
economy for quarters beginning after December 31, 1998 and, effective January 1,
1999,  the  Company  expects to  designate  the Mexican  peso as the  functional
currency  for its  Mexican  operations  (as  compared to the U.S.  dollar).  The
Company does not expect this change to have a material  impact on its  financial
results in fiscal 1999.

Interest Risk

The fair  market  value of  long-term  fixed  interest-rate  debt is  subject to
interest-rate risk. Generally, the fair market value of fixed interest-rate debt
will increase as interest  rates fall and decrease as interest  rates rise.  The
estimated fair value of the Company's total  long-term debt  (including  current
portion)  approximated  $53.4  million at September  30, 1998,  as compared to a
recorded value of $60.8 million.  The Company  estimates that a 1% increase from
prevailing  interest  rates at September 30, 1998 would reduce the fair value of
total long-term debt by approximately $1.4 million.  See Note 1 to the "Notes to
Consolidated  Financial  Statements"  under  the  sub-caption  "Fair  Values  of
Financial Instruments" for further discussion.

Financial Condition and Liquidity

Future cash  requirements are planned to be satisfied from a combination of cash
balances  ($3.8  million at  September  30,  1998),  from  borrowings  under its
revolving  credit line ($22.6  million of  additional  borrowings  available  at
September  30,  1998) and from  alternate  financing  sources.  These  alternate
sources  are  targeted  to  include  the  sale of  assets,  technologies  and/or
interests  in existing  businesses.  For example,  in December  1998 the Company
negotiated the sale of its Technology Alliance Group, a division responsible for
developing,  patenting and licensing advanced modem and access technologies, for
approximately $16.3 million ($12.0 million of net proceeds after related selling
costs).

In addition,  on December 18, 1998, the Company announced a restructuring of its
business  into three primary  operating  units and the intent to sell or partner
certain other  operations.  The Company  anticipates  annual  operating  expense
reductions to exceed $15.0 million when the plan is fully implemented.

Refer to Note 15 to the "Notes to Consolidated Financial Statements" for further
discussion of the business restructuring and the sale of an operating division.

On October 22, 1997, the Company  entered into a $40.0 million loan and security
agreement (the "Loan  Agreement")  with a new lending group.  The Loan Agreement
provided the Company with $15.0 million in proceeds  from a five-year  term loan
and an additional  $25.0 million  (maximum value) revolving line of credit for a
three-year period ending in October 2000, subject to extension.  Availability of
such funds is subject to satisfying a borrowing  base formula  related to levels
of  certain  accounts  receivable  and  inventories  and  satisfaction  of other
financial  covenants.  Such formula and  covenants  were amended on November 25,
1998, and are discussed below.

The Loan  Agreement's  covenants  may,  if  violated,  limit  access  to  future
borrowings and may accelerate  payment  requirements on outstanding  borrowings.
The two most restrictive  covenants are as follows: (1) the requirement to raise
a minimum of $10.0  million of net proceeds from the sale of assets or execution
of an equity  offering on or before March 31, 1999 (the Company  satisfied  this
requirement  on December 30, 1998, as discussed in further  detail  below),  and
that a portion of the net  proceeds  (40% of the first $10.0  million and 20% of
net proceeds in excess of $10.0 million,  not to exceed $6.0 million) be applied
to the  term  loan  portion  of the Loan  Agreement  upon  receipt;  and (2) the
requirement  to maintain  specified  minimum  balances  consisting of the sum of
stockholders'  equity  (excluding  foreign  currency   translation   adjustments
subsequent to September 30, 1997 and  restructuring  charges  recorded in fiscal
1998  or  thereafter,  not to  exceed  $4.5  million),  and  outstanding  7-3/4%
convertible  debentures  ("minimum  equity  balance").  Minimum  equity  balance
requirements  under the Loan Agreement  amount to $67.9 million,  $62.9 million,
$59.5 million,  $57.1 million and $57.0 million on September 30, 1998,  December
31, 1998,  March 31, 1999,  June 30, 1999 and September 30, 1999,  respectively,
and  increases  by $1.0  million per quarter for  subsequent  quarters.  As such
minimum equity  balance at September 30, 1998 was $74.2  million,  this covenant
effectively  limits the sum of  cumulative  future  losses and  preferred  stock
dividend payments,  less 60 percent of the value of new capital stock issued, to
$17.2 million  (excluding  restructuring  charges of up to $2.0 million).  Other
covenants  require that the Company maintain a current ratio equal to or greater
than 1.4 and that annual capital expenditures not exceed $15.0 million.

Since the Company  realized  losses of $6.2  million  and $33.4  million for the
quarter and year ended September 30, 1998,  respectively,  a combination of cost
reductions  and/or  revenue  growth  is  required  in  fiscal  1999 to  maintain
compliance with the minimum equity balance  covenant.  In addition,  the Company
must sell assets or execute an equity  offering to achieve the $10.0  million in
net proceeds  required under the Loan  Agreement.  (See Note 15 to the

                                       13
<PAGE>

"Notes to Consolidated  Financial  Statements" for a discussion of the sale of a
Company  division  subsequent  to September  30, 1998 which  satisfied the $10.0
million  covenant.)  In the  event of  non-compliance  with  financial  or other
covenants,  the  Company  would  have to obtain a waiver or  amendment  from the
lender,  and there is no assurance  that the lender would grant such a waiver or
amendment.  The Company's  inability to have access to the Loan Agreement and/or
alternative  financing  sources  would  have a  material  adverse  effect on the
Company's  financial  condition.  Management has implemented and is committed to
execute  further cost  reduction  actions as necessary to improve the  Company's
operating results and maintain availability of funding under the Loan Agreement.
Refer  to  Note  6 of the  "Notes  to  Consolidated  Financial  Statements"  for
additional information on the Loan Agreement.

Operating

Net cash used in operating activities amounted to $1.0 million in fiscal 1998 as
compared  to $7.1  million of net cash used in  operating  activities  in fiscal
1997. The  improvement of $6.1 million is primarily  attributable to the smaller
net loss reported in fiscal 1998.

Non-debt working capital,  excluding cash and cash  equivalents,  decreased from
$38.0 million at September 30, 1997 to $29.5 million at September 30, 1998.  The
decrease of $8.5 million  reflects,  among other items, a $3.2 million reduction
in accounts  receivable  (resulting  from a reduced level of sales  activity and
continued  improvement  with  collection  efforts) and an $11.2 million  managed
reduction in inventory, offset in part with reductions in accounts payable ($2.5
million)  associated  with the reduction in inventory  levels,  accrued  payroll
costs  ($1.0  million),  accrued  taxes  ($1.8  million)  and other  items ($0.6
million).

Investing

The  Company  continued  to  invest  in new  technologies  during  fiscal  1998.
Property, plant and equipment investments totaled $6.9 million in fiscal 1998 as
compared to $11.6 million in fiscal 1997.  Investments in  capitalized  software
amounted  to  $12.7   million  and  $12.1  million  in  fiscal  1998  and  1997,
respectively.

Financing

Net cash  provided by  financing  activities  amounted to $2.7 million in fiscal
1998,  comprised of $3.5 million in net borrowings  (including the $15.0 million
term loan referenced  above),  $1.0 million of proceeds  received for stock sold
under the employee stock  purchase  plan,  less $1.8 million used for payment of
preferred  stock  dividends.  In fiscal  1997,  net cash  provided by  financing
activities  amounted to $26.2 million,  reflecting $23.6 million of net proceeds
from the  issuance of 7-3/4%  convertible  debentures  (described  below),  $1.8
million of proceeds from the issuance of common stock pursuant to employee stock
programs and net debt  borrowings  of $2.6 million,  partially  offset with $1.8
million in preferred stock dividend payments.

Reference is made to the discussion  above regarding the Company's $40.0 million
Loan Agreement, including related terms and financial covenant restrictions.

On September 26, 1997, the Company  issued $25.0 million of  convertible  senior
subordinated  debentures  ("Debentures")  which mature on September 30, 2002 (if
not  converted or redeemed)  and accrue  interest at a rate of 7-3/4% per annum.
Such  Debentures,  issued  to  qualified  institutional  buyers  and  accredited
institutional  investors,  are convertible  into shares of the Company's  common
stock. Refer to Note 6 of the "Notes to Consolidated  Financial  Statements" for
additional disclosure.
 
In  September  1996,  the  Company  completed  the  sale of  800,000  shares  of
cumulative convertible exchangeable preferred stock ("Preferred Stock") pursuant
to a private placement offering resulting in net proceeds of $19.2 million.  The
Preferred Stock,  sold for $25.00 per share,  accrues  dividends at a rate of 9%
($1.8 million) per annum,  cumulative from the date of issuance and payable on a
quarterly  basis in arrears.  The Preferred  Stock can be converted  into common
stock at $13.65 per share,  or the  equivalent  of 1.8315 shares of common stock
for each share of Preferred Stock.  Reference is made to Note 9 of the "Notes to
Consolidated   Financial   Statements"  for  additional   disclosure   regarding
conversion terms and options.

Lease Financing Agreements

The Company's  leasing  subsidiary has in the past entered into  agreements with
financial  institutions  whereby  lease  receivables  are  transferred  to  such
institutions with full recourse.  However,  no such agreements were entered into
in  fiscal  1998.  Refer  to Note 12 of the  "Notes  to  Consolidated  Financial
Statements" for further discussion.

Operating Lease Obligations

See Note 8 of the "Notes to Consolidated Financial Statements" for discussion of
the Company's operating lease obligations.

Concentrations of Credit

Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash instruments and accounts receivable. The
Company places its cash investments  with  high-quality  financial  institutions
within the U.S., and as of September 30, 1998 and 1997,  maintained  balances of
approximately  $0.5  million  and  $20.2  million,  respectively,  with one such
institution.

Approximately  $16.2  million,  or 45% of  consolidated  accounts  receivable at
September  30, 1998  ($15.1  million,  or 39%,  at  September  30,  1997),  were
concentrated  in  telephone  companies  in  North  America  and  Europe.   These
receivables  are not  collateralized  due to the  high  credit  ratings  and the
extensive financial resources available to such telephone companies.

Impact of Inflation and Changing Prices

In  management's  opinion,  the impact of inflation and changing  prices for the
three most recent fiscal years is not significant to the financial statements as
reported.

Future Adoption of New Accounting Statements

Newly issued  pronouncements  to become  effective in fiscal 1999 or fiscal 2000
are not currently expected to have a material impact on the Company's  financial
position or results of operations. Refer to Note 1 of the "Notes to Consolidated
Financial Statements" for detailed information.

Year 2000 Compliance

Many currently installed computer systems are not capable of distinguishing 21st
century  dates  from 20th  century  dates.  As a result,  in less than two years
computer  systems and/or  software used by many companies in a very wide variety
of applications will experience operating  difficulties unless they are modified
or upgraded to adequately process information involving, related to or dependent
upon the century change. Significant uncertainty exists concerning the scope and
magnitude of problems associated with the century change.

The Company  recognizes the need to ensure its operations  will not be adversely
impacted by Year 2000  software  failures and has  established a project team to
address Year 2000 risks. The project team has coordinated the  identification of
and is  coordinating  the  implementation  of changes to computer  hardware  and
software  applications that will attempt to ensure availability and integrity of
the Company's information systems and the reliability of its operational systems
and manufacturing processes. The Company is also assessing the potential overall
impact of the impending  century  change on its business,  results of operations
and financial position.

The  Company  has  reviewed  its  information   and   operational   systems  and
manufacturing processes in order to identify those products, services or systems
that are not Year 2000  compliant.  As a result of this review,  the Company has
determined that it will be required to modify or replace certain information and
operational systems so they will be Year 2000 compliant. These modifications and
replacements  are being,  and will continue to be, made in conjunction  with the
Company's  overall  systems  initiatives.  The  total  cost of these  Year  2000
compliance activities, estimated at less than $1.0 million, has not been, and is
not  anticipated  to be,  material to the  Company's  financial  position or its
results of  operations.  These costs are being expensed as they are incurred and
are being funded through  operating cash flow.  These amounts do not include any
costs associated with the  implementation of contingency plans, which are in the
process  of being  developed.  The  costs  associated  with the  replacement  of
computerized systems, hardware or equipment, substantially all of which would be
capitalized,  are not included in the above  estimates.  The Company  expects to
complete its Year 2000 project during fiscal 1999.

                                       15
<PAGE>

Based on  available  information,  the Company  does not  believe  any  material
exposure to significant  business  interruption  exists as a result of Year 2000
compliance  issues. The Company plans to develop formal contingency plans in the
event it appears  unlikely that its Year 2000 project will not be completed in a
timely manner. These costs and the timing in which the Company plans to complete
its Year 2000  modification and testing processes are based on management's best
estimates.  However,  there can be no  assurance  that the  Company  will timely
identify and remediate all significant Year 2000 problems, that remedial efforts
will not involve  significant  time and expense,  or that such problems will not
have a material adverse effect on the Company's business,  results of operations
or financial position.

The Company also faces risk to the extent that  suppliers of products,  services
and systems  purchased by the Company and others with whom the Company transacts
business on a worldwide  basis do not comply  with Year 2000  requirements.  The
Company has  initiated  formal  communications  with  significant  suppliers and
customers to determine  the extent to which the Company is  vulnerable  to these
third parties' failure to remediate their own Year 2000 issues. In the event any
such third parties cannot provide the Company with products, services or systems
that meet the Year 2000  requirements  on a timely  basis,  or in the event Year
2000 issues  prevent  such third  parties  from  timely  delivery of products or
services  required by the Company,  the Company's results of operations could be
materially adversely affected.  To the extent Year 2000 issues cause significant
delays in, or cancellation of,  decisions to purchase the Company's  products or
services,  the Company's business,  results of operations and financial position
would be materially adversely affected.

The Company  believes  that it has  substantially  identified  and  resolved all
potential  Year 2000 problems with any of the software  products it develops and
markets to customers.  However, management also believes that it is not possible
to determine with complete  certainty that all Year 2000 problems  affecting the
Company's  software products have been identified or corrected due to complexity
of  these  products  and the  fact  that  these  products  interact  with  other
third-party  vendor products and operate on computer systems which are not under
the Company's control.

The discussion of the Company's efforts and management's  expectations  relating
to Year  2000  compliance  are  forward-looking  statements  which  are  further
discussed below.  The Company's  ability to achieve Year 2000 compliance and the
level of incremental costs associated therewith, could be adversely impacted by,
among  other  things,  the  availability  and cost of  programming  and  testing
resources,  vendors' ability to modify proprietary  software,  and unanticipated
problems identified in ongoing compliance review.

No cash dividends  have ever been paid on the Company's  common stock or Class B
stock.  The Company's  principal  loan  agreement does not allow payment of cash
dividends,  with the  exception  of  dividends  authorized  for  payment  on the
Company's  preferred  stock.  In  the  event  this  would  change,  it is  still
management's  intention to reinvest  future  earnings in the business to support
growth plans.

The Company had  approximately  1,860  shareholders  of record at September  30,
1998.

                      Notes to Consolidated Financial Statements

1.  Description Of Business and Summary of Significant Accounting Policies
 
Description of Business

The   Company   is  a   worldwide   provider   of  wide  area   networking   and
telecommunications  products. The Company designs, assembles,  markets, installs
and  maintains  products  and  services  that enable  telecommunications  common
carriers, corporations and governments to build, upgrade and better manage their
global telecommunications  networks. Products include asynchronous transfer mode
(ATM) broadband switches, network access products, including advanced xDSL-based
network access systems,  time-division  multiplexing (TDM) equipment and network
management systems. The Company also provides comprehensive support services.

Principles of Consolidation

The consolidated  financial  statements  include the accounts of the Company and
its majority-owned subsidiary companies. Intercompany accounts, transactions and
profits have been appropriately eliminated in consolidation.

Inventories

Inventories  are  stated  at the  lower  of cost  or  market  using a  first-in,
first-out method.

Property, Plant and Equipment

Property,  plant and equipment are stated at cost and  depreciated  or amortized
using the  straight-line  method over their estimated  useful lives. The cost of
internally  constructed  assets (test fixtures)  includes the cost of materials,
internal labor and overhead costs.

Capitalized Software Development Costs

Software  development costs are capitalized for those products that have met the
requirements   of   technological   feasibility.   Such   costs  are   amortized
straight-line, on a product-by-product basis over the estimated economic life of
the  product.   Unamortized  costs  are  reviewed  for  recoverability  and,  if
necessary,  adjusted so as not to exceed  estimated net  realizable  value.  The
accumulated  amortization of capitalized  software development costs amounted to
$17,972,000 and $16,127,000 at September 30, 1998 and 1997, respectively.

Goodwill

Goodwill  is  amortized  to  expense  over  its  estimated  useful  life,  which
approximates  15  years,   using  the  straight-line   method.   The  valuation,
recoverability and amortization of goodwill is reviewed on a periodic basis. The
remaining  unamortized portion of goodwill (included in the Consolidated Balance
Sheets under "Other Assets")  amounted to $4,578,000 and $4,999,000 at September
30,  1998 and 1997,  respectively.  The  accumulated  amortization  of  goodwill
amounted  to  $2,469,000   and  $2,048,000  at  September  30,  1998  and  1997,
respectively.

Revenue Recognition

Revenue from  equipment  sales is generally  recognized  at the date of shipment
unless the terms and conditions of the sale dictate recognition at a later date.
Technology  licensing  fee  revenue is  recognized  in the period  received  or,
alternatively,  may be accrued when reliably  determinable.  Service  revenue is
either  recognized  when the service is performed or, in the case of maintenance
contracts, on a straight-line basis over the term of the contract.

Revenue from  sales-type  leases is recognized at the date of shipment.  Revenue
from operating leases is recognized ratably over the lease term, and the related
equipment  is  depreciated  using the  straight-line  method over its  estimated
useful life, which  approximates four years. The average length of initial lease
terms in fiscal  1998 was  approximately  31 months.  Leasing  revenue  includes
income  from  the  transfer  (with  full  recourse)  of  certain  finance  lease
receivables.  No such  income  was  recognized  in fiscal  1998 and such  income
amounted to $195,000 and $553,000 in fiscal 1997 and 1996, respectively.

Promotion and Advertising Costs

Promotion and advertising  costs are charged to operating  expense in the fiscal
year in which they are incurred.  Promotion and  advertising  costs  amounted to
$5,287,000,   $7,007,000  and   $6,528,000  in  fiscal  1998,   1997  and  1996,
respectively.

Income Taxes

The Company  accounts  for income  taxes under the  provisions  of  Statement of
Financial  Accounting  Standards No. 109,  "Accounting  for Income Taxes," which
requires the use of the  liability  method of  accounting  for  deferred  income
taxes.

The provision for income taxes includes federal, foreign, state and local income
taxes currently payable and deferred taxes resulting from temporary  differences
between the  financial  statement and tax basis of assets and  liabilities.  The
Company  intends to  permanently  reinvest  the  undistributed  earnings  of its
foreign subsidiaries  ($5,474,000 at September 30, 1998).  Accordingly,  no U.S.
federal  income  taxes have been  provided on such  earnings.  In  addition,  no
significant  taxes would be required if such  earnings  were remitted due to net
operating loss carryforwards available in the United States.

Earnings (Loss) Per Share

Earnings  (loss) per share is computed  under the  provisions  of  Statement  of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), which
the Company  adopted in fiscal 1998.  SFAS 128 replaced the previously  reported
primary and fully diluted earnings per share with basic and diluted earnings per
share, respectively. Unlike primary earnings per share, basic earnings per share
excludes any dilutive effects of options,  warrants, and convertible securities.
Diluted  earnings per share is very  similar to the  previously  reported  fully
diluted  earnings per share.  SFAS 128 requires  restatement of all prior period
earnings per share information to conform to the new reporting requirements.

Under current and prior accounting  standards,  common stock equivalents are not
factored  into  earnings per share  calculations  for  companies  reporting  net
losses.  As a result,  implementation  of SFAS 128 did not have an impact on the
Company's  reported loss per share information for the years ended September 30,
1998,  1997 or 1996.  Separately,  the  pronouncement  is not expected to have a
material impact on the Company's  reported earnings (loss) per share information
in the near  term.  Refer to Note 13 to the  "Notes  to  Consolidated  Financial
Statements" for further information.

Concentrations of Credit Risk

Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash instruments and accounts receivable. The
Company  places  its  cash  investments   with   high-quality   U.S.   financial
institutions and maintained  balances of approximately  $531,000 and $20,200,000
with one such institution at September 30, 1998 and 1997, respectively.

Approximately  $16,185,000,  or 45%,  of  consolidated  accounts  receivable  at
September  30,  1998   ($15,144,000,   or  39%,  at  September  30,  1997)  were
concentrated  in  telephone  companies  in  North  America  and  Europe.   These
receivables  are not  collateralized  due to the  high  credit  ratings  and the
extensive financial resources available to such telephone companies.

Foreign Currency

Assets and liabilities of the Company's foreign  subsidiaries in countries other
than Mexico are translated  using fiscal year-end  exchange rates,  and revenues
and expenses are translated using average  exchange rates prevailing  during the
year. The effects of translating such foreign subsidiaries' financial statements
are recorded as a separate  component of  stockholders'  equity.  As a result of
high inflation in Mexico,  effective January 1, 1997 the Company was required to
change  its  method of  translating  the  financial  statements  of its  Mexican
subsidiary  to reflect  the  designation  of the U.S.  dollar as the  functional
currency. As a result,  certain assets,  liabilities and expenses are translated
using  historical  exchange  rates and the  effects of  translating  the Mexican
subsidiary's  financial  statements are recorded in the Company's  statements of
operations.  The  impact  of this  change  was  not  material  to the  Company's
financial results in fiscal 1998 or 1997.

                                       22

<PAGE>

Mexico will cease being  considered a highly  inflationary  economy for quarters
beginning  after  December  31,  1998.  Effective  January 1, 1999,  the Company
expects to designate the Mexican peso as the functional currency for its Mexican
operations  (as compared to the U.S.  dollar).  The Company does not expect this
change to have a material impact on its financial results in fiscal 1999.

Included in other income are net recognized  foreign currency exchange losses of
$400,000, $1,038,000 and $325,000 for fiscal 1998, 1997 and 1996, respectively.

Post-Retirement and Post-Employment Benefits

The Company accounts for post-retirement  benefits and post-employment  benefits
under the  provisions  of Statement of Financial  Accounting  Standards No. 106,
"Employer's  Accounting for  Post-Retirement  Benefits Other Than Pensions," and
Statement of Financial Accounting Standards No. 112, "Employers'  Accounting for
Post-Employment  Benefits,"  respectively,  each of which requires the use of an
accrual  method of accounting  for such  benefits.  The annual expense and other
disclosure information applicable to such benefits is not material.

Accounting for Stock-Based Compensation

As  permitted  under  Statement  of  Financial  Accounting  Standards  No.  123,
"Accounting for Stock-Based  Compensation,"  the Company has elected to continue
to  measure  costs  for its  employee  stock  compensation  plans by  using  the
accounting  methods  prescribed by Accounting  Principles  Board Opinion No. 25,
"Accounting  for Stock Issued to Employees,"  which allows that no  compensation
cost be recognized  provided the exercise  price of options  granted is equal to
the fair market value of the Company's stock at date of grant. Reference is made
to Note 11 of the  "Notes to  Consolidated  Financial  Statements"  for  further
information.

Future Adoption of New Accounting Statements

SFAS No. 130, "Reporting  Comprehensive  Income," establishes  standards for the
reporting  and display of  comprehensive  income and its  components  (revenues,
expenses,  gains  and  losses)  in  a  full  set  of  general-purpose  financial
statements. The Company will adopt SFAS No. 130 in fiscal 1999.

SFAS  No.  131,  "Disclosures  about  Segments  of  an  Enterprise  and  Related
Information," which, among other things, changes the way public companies report
information about operating segments,  also becomes effective for the Company in
fiscal 1999.  The Company,  which  currently  operates  solely in the multimedia
communications   industry,   is  currently   evaluating   the  effects  of  this
pronouncement on its reporting of segment information.

SFAS No. 132,  "Employers'  Disclosures about Pensions and Other  Postretirement
Benefits,"  which  revises  disclosure  requirements  about  pensions  and other
postretirement  benefit plans (the Statement does not change the  measurement or
recognition  of  applicable  plans),  will become  effective  for the Company in
fiscal 1999. The Company has not yet evaluated the effects of this pronouncement
on future related disclosures.
 
Statement Of Position 97-2,  "Software  Revenue  Recognition,"  ("SOP 97-2") was
issued by the Accounting  Standards  Executive Committee on October 27, 1997 and
provides  guidance on  applying  generally  accepted  accounting  principles  in
recognizing  revenue on software  transactions.  Mandatory  compliance  with the
accounting  principles set forth in SOP 97-2 has been deferred until fiscal year
2000  (earlier   application  is  encouraged  and  retroactive   application  is
prohibited);  implementation  of such  accounting  principles  is not  presently
expected to have a material impact on the Company's  reported financial position
or results of operations.

Fair Values of Financial Instruments

Cash and cash  equivalents - The carrying  amount  reported in the  consolidated
balance  sheets  for cash and cash  equivalents  approximates  fair value due to
their short-term nature.

Long-term  debt - The estimated  fair value of the  Company's  $60.8 million and
$56.9 million total long-term debt (including  current portion) at September 30,
1998 and 1997, respectively,  was approximately $53.4 million and $56.9 million,
respectively.  In the case of variable  interest-rate  debt,  debt with  shorter
maturities and recently secured fixed  interest-rate debt, the Company estimates
the  fair  value  to  be  the  carrying  value.  For  other   long-term,   fixed
interest-rate  debt,  the  estimated  fair value was obtained from an investment
banker.

                                       23
<PAGE>

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
the  reported  amounts of revenues  and expenses  during the  reporting  periods
presented.  Actual results could differ from those estimates.  For example,  the
markets for the Company's  products are  characterized  by intense  competition,
rapid technological  development and frequent new product introductions,  all of
which could  impact the future  value of the  Company's  inventory,  capitalized
software and certain other assets.

Reclassifications

Certain  reclassifications  were  made to prior  years'  consolidated  financial
statements to conform to the current year's presentation.

2.  Restructuring Of Operations

The fiscal year ended September 30, 1998 includes a restructuring  of operations
charge of $2,500,000, or $0.12 per share (basic and diluted), which is comprised
of a  $1.0  million  provision  for  post-employment  benefits  related  to  the
elimination of  approximately  200 full-time  positions and $1.5 million for the
write-off of intangible  assets and other costs  associated with the elimination
of low-volume  product lines. The restructuring  actions,  initiated on or about
January 2, 1998, were complete at September 30, 1998.

3.  Technology Licensing Agreements

The Company has entered into numerous  technology  licensing  agreements whereby
licensees pay the Company  license fees for the use or sale of specific  patents
and/or technology.  Technology  licensing revenues from such agreements amounted
to  $3,166,000,  $4,929,000  and  $6,131,000  in  fiscal  1998,  1997 and  1996,
respectively. Fiscal 1996 licensing revenue includes $2,459,000 of fees received
from one  customer,  a  significant  portion of which  represented a retroactive
application of license fees.  Licensing revenues are reported as "Other Revenue"
in the Company's Consolidated Statements of Operations.  Refer to Note 15 to the
"Notes to Consolidated  Financial  Statements" for a discussion of the a sale of
the Technology Alliance Group division,  which generates licensing fee revenues,
on December 31, 1998.

</TABLE>

Revolving Credit Facility

On October 22, 1997, the Company  entered into a $40.0 million loan and security
agreement (the "Loan  Agreement")  with a new lending group.  The Loan Agreement
provided  the Company  with $15.0  million in proceeds  (received on October 22,
1997) from a five-year term loan and an additional $25.0 million (maximum value)
revolving line of credit for a three-year period ending in October 2000, subject
to  extension.  Availability  of such funds is subject to satisfying a borrowing
base formula related to levels of certain  accounts  receivable and inventories,
and satisfaction of other financial  covenants.  Such formula and covenants were
amended on November  25, 1998,  along with  changes in interest  rates and other
items, as discussed below.

Interest on borrowings  under the  revolving  line will be charged at the higher
of: (1) the prime rate of interest plus 1% (2% effective  November 25, 1998); or
(2) a published  annualized rate for 90-day dealer  commercial paper plus 1% (2%
effective  November 25, 1998).  On September 30, 1998,  the prime rate was 8.25%
and the applicable 90-day dealer  commercial paper rate was 5.12%.  Most assets
of the Company,  including accounts receivable,  inventories and property, plant
and  equipment,  are  pledged as  collateral.  Borrowings  and letters of credit
outstanding  under this  revolving  line of credit portion of the Loan Agreement
were $1,587,000 and $763,000,  respectively,  at September 30, 1998;  borrowings
and  letters  of  credit  outstanding  under a  separate  credit  facility  were
$4,799,000 and $935,000, respectively, at September 30, 1997.

The Loan  Agreement's  covenants  may,  if  violated,  limit  access  to  future
borrowings and may accelerate  payment  requirements on outstanding  borrowings.
The two most restrictive  covenants are as follows: (1) the requirement to raise
a minimum of $10.0  million of net proceeds from the sale of assets or execution
of an  equity  offering  on or  before  March  31,  1999  (reference  is made to
discussion  below  regarding  satisfaction  of this  requirement on December 30,
1998),  and that a portion of the net proceeds  (40% of the first $10.0  million
and 20% of net proceeds in excess of $10.0 million,  not to exceed $6.0 million)
be applied to the term loan portion of the Loan Agreement upon receipt;  and (2)
the requirement to maintain specified minimum balances  consisting of the sum of
stockholders'  equity  (excluding  foreign  currency   translation   adjustments
subsequent to September 30, 1997 and  restructuring  charges  recorded in fiscal
1998  or  thereafter,  not to  exceed  $4.5  million),  and  outstanding  7-3/4%
convertible  debentures  ("minimum  equity  balance").  Minimum  equity  balance
requirements under the Loan Agreement

                                       25

                                       
<PAGE>

amount to $67.9 million,  $62.9 million,  $59.5 million, $57.1 million and $57.0
million on September 30, 1998,  December 31, 1998, March 31, 1999, June 30, 1999
and September 30, 1999, respectively,  and increases by $1.0 million per quarter
for  subsequent  quarters.  As such minimum equity balance at September 30, 1998
was $74.2 million, this covenant effectively limits the sum of cumulative future
losses and preferred  stock dividend  payments,  less 60 percent of the value of
new capital stock issued, to $17.2 million (excluding  restructuring  charges of
up to $2.0 million). Other covenants require that the Company maintain a current
ratio equal to or greater  than 1.4 and that  annual  capital  expenditures  not
exceed $15.0 million.

Since the Company  realized  losses of $6.2  million  and $33.4  million for the
quarter and year ended September 30, 1998,  respectively,  a combination of cost
reductions  and/or  revenue  growth  is  required  in  fiscal  1999 to  maintain
compliance with the minimum equity balance  covenant.  In addition,  the Company
must sell assets or execute an equity  offering to achieve the $10.0  million in
net proceeds required under the Loan Agreement (see Note 15 "Subsequent  Events"
to the "Notes to  Consolidated  Financial  Statements"  regarding  the sale of a
Company  division  subsequent  to September  30, 1998 which  satisfies the $10.0
million  covenant.)  In the  event of  non-compliance  with  financial  or other
covenants,  the  Company  would  have to obtain a waiver or  amendment  from the
lender and there is no  assurance  that the lender  would grant such a waiver or
amendment.  The Company's  inability to have access to the Loan Agreement and/or
alternative  financing  sources  would  have a  material  adverse  effect on the
Company's  financial  condition.  Management has implemented and is committed to
execute  further cost  reduction  actions as necessary to improve the  Company's
operating results and maintain availability of funding under the Loan Agreement.

Notes Payable

On October 22, 1997,  the Company  received  proceeds of $15.0  million from the
term loan portion of the above-referenced  Loan Agreement.  The term loan, whose
outstanding  balance  amounted to  $14,136,402  at  September  30,  1998,  bears
interest at a rate of 11.51% per annum (12.51% per annum effective  November 25,
1998), and is payable in 20  predetermined  quarterly  installments,  with final
payment due on September 15, 2002 (the  prepayments  referenced  above,  payable
from proceeds received from the sale of assets, not to exceed $6.0 million, will
be applied to future term loan  payments).  Separately,  the Company has entered
into three-,  four-,  and five-year  note and  installment  purchase  agreements
collateralized by certain machinery, test equipment, furniture and fixtures. The
outstanding  balance of $9,037,000 at September 30, 1998, which approximates the
net book  value of the  underlying  equipment,  bears  interest  at fixed  rates
ranging  from  6.5% to  11.59%,  or a  variable  rate  equal to  prime  plus 1%.
Individual notes mature between fiscal 1999 and fiscal 2001.

Convertible 7-3/4% Debentures

On September 26, 1997, the Company  issued $25.0 million of  convertible  senior
subordinated  debentures  ("Debentures")  which mature on September 30, 2002 (if
not  converted or redeemed)  and accrue  interest at a rate of 7-3/4% per annum.
Such  Debentures,  issued  to  qualified  institutional  buyers  and  accredited
institutional  investors,  are convertible  into shares of the Company's  common
stock at a conversion price of $6.279 per share (as adjusted on March 30, 1998),
or the  equivalent  of 159.3  shares of common  stock for each $1,000  principal
amount of Debentures.  Under certain  conditions,  such conversion  price may be
reset to a reduced  price per share on September  30, 1999,  but in no event may
the  conversion  price be reset  below  $5.831 per  share.  The  Debentures  are
subordinated  in right of payment to most other  indebtedness of the Company and
are equal to or senior to other subordinated indebtedness of the Company.

The  Debentures  may not be redeemed by the Company  prior to September 30, 2000
and are redeemable in whole or in part, at the option of the Company,  at 103.1%
of principal  value during the period  September 30, 2000 through  September 29,
2001 if certain  conditions  are met, and without  conditions  at 101.55% of the
principal  value on or after September 30, 2001 or 100% of principal value on or
after September 30, 2002 (maturity).

During the 30-day  period  commencing  September  30,  2000,  each holder of the
Debentures  can require  the Company to  repurchase  the  Debentures  at 100% of
principal value. The Company may satisfy such repurchase obligations through the
issuance of non-convertible  senior subordinated notes which are subordinated to
the same extent,  due on the same maturity date and have  substantially the same
terms as the Debentures, except such newly issued notes shall not be convertible
and will bear a rate of  interest  required  for such new  securities  to have a
market value equal to

100% of their principal amount on the date of repurchase,  but in no event shall
such interest rate exceed 14% per annum.

Mortgages Payable

Mortgages outstanding on the Company's corporate  headquarters and manufacturing
facilities,  which bear  interest at 90-day LIBOR (5.25% at September  30, 1998)
plus 2%,  amounted to $9,825,000 and $10,225,000 at September 30, 1998 and 1997,
respectively.  Quarterly principal payments of $100,000 are required until these
mortgages  mature in the year 2003. In addition,  two mortgages  with  remaining
principal balances totaling  $1,227,000 and $1,485,000 at September 30, 1998 and
1997,  respectively,  were outstanding on the Company's  buildings in the United
Kingdom.  These  mortgages bear interest at six-month  LIBOR (5.16% at September
30, 1998) plus 1.3% and mature in fiscal 2003.

For regular  income tax reporting  purposes at September  30, 1998,  foreign and
domestic  tax credits and net  operating  loss  carryforwards  amounted to $10.3
million and $151.0 million, respectively. Domestic federal loss carryforwards of
$144.0 million expire between fiscal 2004 and 2014, of which approximately $12.6
million  relate to items  which will be credited  to  stockholders'  equity when
applied;  domestic  state loss  carryforwards  of $66.0 million  expire  between
fiscal  1999  and  2014.  Foreign  loss  carryforwards  of $8.0  million  expire
beginning in fiscal 1999.  Tax credit  carryforwards  expire between fiscal 1999
and 2014.

For federal alternative  minimum tax purposes,  net operating loss carryforwards
amounted to $137.0  million at September 30, 1998.  These  carryforwards  may be
carried forward  indefinitely to offset any excess of regular tax liability over
alternative   minimum  tax  liability,   subject  to  certain  separate  company
limitations.

The tax effects of the significant temporary differences comprising the deferred
tax assets and  liabilities  at  September  30, 1998 and 1997 are as follows (in

Statement  of Financial  Accounting  Standard  No. 109,  "Accounting  For Income
Taxes," requires a valuation  allowance against deferred tax assets if, based on
available evidence,  it is more likely than not that some or all of the deferred
tax assets will not be realized.  The Company believes that  uncertainty  exists
with respect to the future  realization of deferred tax assets and, as a result,
carries  a  valuation  allowance  for  such  items.  The  valuation  allowances,
disclosed in the  deferred  tax summary  above,  increased  by  $17,601,000  and
$15,572,000 in fiscal 1998 and fiscal 1997, respectively.

8.  Operating Leases

The  Company  has  certain  non-cancelable   operating  leases  on  automobiles,
subsidiary  locations,  sales offices and service facilities which expire within
one to six years.  These leases generally contain renewal options and provisions
for payment by the lessee of executory costs (taxes, maintenance and insurance).
In addition,  the Company has a  non-cancelable  operating  lease through fiscal
2003 for its Connecticut engineering facility.

The  following  is a schedule of the future fiscal year minimum  payments on
such leases at September 30, 1998 (in thousands):

The Common Stock  referenced above includes both Class B stock and common stock.
Class B stock,  under  certain  circumstances,  has greater  voting power in the
election of directors.  However,  common stock is entitled to cash dividends, if
and when paid, 11.11% higher per share than Class B stock. The Company has never
declared or paid cash  dividends on its common stock and terms of the  Company's
revolving credit facility prohibit the Company from paying cash dividends,  with
the exception of dividends  authorized  for payment on the  Company's  preferred
stock  (referenced  below).  Class B stock has  limited  transferability  and is

Employee Stock Purchase Plan

The Company has a stock  purchase plan to encourage  employees to participate in
the Company's future growth. At September 30, 1998, 308,407 shares were reserved
for purchase by employees through payroll deductions regularly  accumulated over
six-month  payment periods.  At the end of each payment period,  Common Stock is
purchased  at 85 percent  of the market  value of the stock on the first or last
day of the payment periods,  whichever is lower. However, the purchase of Common
Stock  under this plan is  prohibited  if 85 percent of the market  value of the
Common  Stock is less than the book  value  per  share.  Note 9,  "Stockholders'
Equity,"  presents  the  historical  activity  under this plan  during the three
fiscal years ended September 30, 1998.

Employee Retirement Savings and Deferred Profit Sharing Plan

Under  the  retirement  savings  provisions  of the  Company's  retirement  plan
established  under Section  401(k) of the Internal  Revenue Code,  employees are
generally  eligible to  contribute  to the plan after three months of continuous
service,  in  amounts  determined  by  the  plan.  The  Company  contributes  an
additional 50 percent of the employee  contribution up to certain limits (not to
exceed 2 percent of total eligible compensation).  Employees become fully vested
in the Company's  contributions after three years of continuous service,  death,
disability  or upon  reaching  age 65. The  amounts  charged to expense  for the
fiscal years ended September 30, 1998, 1997 and 1996 were $1,015,100, $1,133,200
and $919,600, respectively.

The deferred profit sharing  provisions of the plan include retirement and other
related benefits for  substantially  all of the Company's  full-time  employees.
Contributions  under the plan are funded  annually and are based,  at a minimum,
upon a formula  measuring  profitability  in  relation to  revenues.  Additional
amounts may be contributed at the discretion of the Company.  There were no such
contributions for fiscal 1998, 1997 or 1996.

Stock-Based Compensation

Pro-forma  results,  representative  of financial  results which would have been
reported  by the  Company  if it had  adopted  the fair  value  based  method of
accounting  for  stock-based  compensation  under SFAS No. 123,  are  summarized

The  net  loss  for  the  fiscal  year  ended  September  30,  1998  includes  a
restructuring  charge of $2.5 million,  or $0.12 per share, for restructuring of
operations   (refer  to  Note  2  "Restructuring   of  Operations"  for  further
discussion).

Outstanding securities,  not included in the above computations because of their
antidilutive  impact on reported loss per share,  which could potentially dilute
earnings per share in the future  include  convertible  debentures,  convertible
preferred stock, employee stock options and warrants.  For additional disclosure
information,  including  conversion terms,  refer to Notes 6, 9 and 11. Weighted

in fiscal 1998 diluted earnings per share calculations  because the effect would
be antidilutive.

15.  Subsequent Events

VITAL Network Services,  L.L.C.  Expanded its Partnership With Olicom, Inc. - On
October 15, 1998, the Company's VITAL Network Services  ("VITAL")  business unit
entered into an agreement with Olicom, Inc. whereby VITAL assumed responsibility
for  Olicom's  service  operations  in  Marlborough,  Massachusetts,  and Olicom
assigned or transferred its service contract business in North America to VITAL.
In addition to the assumption of obligations for a leased  facility,  VITAL will
pay up to $3.8  million to Olicom as a  percentage  (25% in the first year,  20%
thereafter) of revenues derived from Olicom's business over a three-year period.
As part of the  agreement,  VITAL  acquired the capital  assets used in Olicom's
service business.  VITAL recorded the acquisition using the purchase  accounting
method which resulted in goodwill of approximately $4.0 million.

Corporate  Reorganization  - On December 18, 1998, the Company  restructured its
operations into three distinct business units to increase product line focus and
move toward  operating  autonomy.  Two (new)  business  units  resulted from the
reorganization: Broadband Systems (ATM and Internetworking products) and Network
Access (Access  products).  The new business units will  supplement the existing
VITAL  Network  Services  business  unit,  which was launched in October 1997 to
provide  professional  services  on  multi-vendor   networking  equipment  on  a
worldwide basis.

The  reorganization,  when  completed,  is  expected  to result  in a  workforce
reduction  of  more  than  200  persons.   This   reduction  will  result  in  a
restructuring  charge of  approximately  $2.5  million,  primarily for severance
costs.

Sale of Technology  Alliance Group Division  ("TAG") - On December 31, 1998, the
Company  reported the sale of its TAG  division.  The Company had been  actively
pursuing  the  sale  of  its  TAG  division  since  it is not  strategic  to the
reorganized  business units mentioned above. The division develops,  patents and
licenses  advanced modem and access  technologies,  is principally  comprised of
scientists and engineers,  and holds the rights to certain technologies patented
by the  division.  The sale  resulted in a pre-tax  gain of  approximately  $9.0
million and generated cash proceeds,  net of expenses,  of  approximately  $12.0
million.
 
Regarding  the Company's  primary Loan  Agreement  (refer to Note 6,  "Long-Term
Debt"),  the net  proceeds  generated  from the sale of TAG will  satisfy a Loan
Agreement  covenant  which required the Company to secure  additional  financial
resources.  The Loan  Agreement  also  provides  that a portion of the  proceeds
(approximately  $4.4 million) be used to reduce  outstanding  indebtedness under
this agreement.

in all  material  respects,  the  consolidated  financial  position  of  General
DataComm  Industries,  Inc. and Subsidiaries at September 30, 1998 and 1997, and
the  consolidated  results of their  operations and their cash flows for each of
the three years in the period ended  September  30,  1998,  in  conformity  with
generally accepted  accounting  principles.  These financial  statements are the
responsibility of the Corporation's management. Our responsibility is to express
an opinion on these financial statements based upon our audits. We conducted our
audits of these  statements  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
