The Company

     TCSI Corporation  ("TCSI" or the "Company")  provides  integrated  software
products and services for the global  telecommunications  ("telecom")  industry.
TCSI's  products  and  services  enable  telecom  service  providers,  equipment
manufacturers,  and systems  integrators  to rapidly meet the growing demand for
automated  management  of a wide range of  networks  and  services.  The Company
offers  SolutionCore(R),  a  telecom  applications  development  and  deployment
platform; SolutionSuites(R), sets of packaged, highly-configurable applications;
and SolutionServicesTM, specialized implementation and consulting services. TCSI
serves its  customers  in offices  throughout  the United  States,  Europe,  and
Asia-Pacific.  TCSI's  software  solutions  are purchased by many of the world's
leading  telecommunications  companies,  including Bell  Atlantic,  Telkom South
Africa,  Nippon Telegraph and Telephone ("NTT"), and IDC in Japan. The Company's
software is also incorporated into telecommunications equipment systems provided
by manufacturers  including Hughes Network Systems,  Motorola,  Italtel,  Lucent
Technologies, Anritsu, and NEC Corporation.

     Since  its  inception  in 1983,  a  significant  portion  of the  Company's
revenues  has  been  earned  from  telecom   service   providers  and  equipment
manufacturers.  Prior to 1997,  the Company also earned  revenue from  licensing
embedded  software  contained in wireless  products and from the  development of
system solutions for customers in the transportation industry. During the second
half of 1996, the Company  divested its  non-telecom  product lines by licensing
its   embedded    software    product   lines   and    terminating   its   final
transportation-related  development  agreement.  As a result,  since  1997,  the
Company has  focused  entirely on  offering  software  solutions  to the telecom
industry.

Industry Background

     The   telecommunications   market  can  be  divided  into  two  tiers:  (i)
traditional full-service providers and network operators,  such as Regional Bell
Operating  Companies ("RBOCs") and national  communications  carriers (incumbent
companies)  and  (ii)  smaller  network  operators  and  independent   telephone
companies  (emerging  companies).  Incumbent  companies  typically  have complex
technical   requirements  and  large  budgets  devoted  to  the  acquisition  of
technology to maintain  their legacy  systems,  enhance their  existing  service
offerings,  and deploy new services and network management systems. In contrast,
emerging telecom companies  typically have limited resources for the acquisition
of  advanced  technology,  but are often more  focused on rapidly  building  new
networks and leveraging proven and more complete systems.  Several recent trends
within the communications  industry are changing the needs of both incumbent and
emerging service providers and of telecom equipment manufacturers.  These trends
include the following:

     o    Increased  competition is driving the need for rapid  introduction  of
          new products.  Deregulation and  privatization of the telecom industry
          worldwide have  intensified  competition  among existing  operators of
          public communications  networks and have encouraged the rapid entry of
          new  service   providers.   Telephone   network  operators  also  face
          increasing competition from cable companies and wireless companies for
          the  provisioning  of telephone  and newer  services,  including  high
          bandwidth data and video. To remain competitive, network operators are
          continually


                                       1
<PAGE>


          seeking to  differentiate  themselves  by improving  existing  service
          offerings and accelerating the time-to-market for new services,  while
          at the same  time  reducing  operational  costs and  downsizing  their
          organizations.  These trends have  increased the need for scalable and
          flexible  software  solutions to enable the rapid  introduction of new
          and  enhanced  services  to a  growing  number of  subscribers  and to
          improve and automate the management of  communications  networks.  The
          need to manage and  respond  quickly to  rapidly  changing  market and
          infrastructure   conditions  has  become  a  focus  for  many  telecom
          companies.

     o    Proliferation of new  communications  services.  Use of communications
          networks  has grown  rapidly in recent  years as a result of increased
          use  of  computing  and  networking  technology,   wireless  services,
          broadband  data and  video  services,  and  other  services.  This has
          resulted in increased  demand for  communications  capacity  worldwide
          from operators of advanced  intelligent  networks,  the Internet,  and
          other   types  of  public   networks.   At  the  same  time,   network
          infrastructures  have  become  more  diverse in order to  provide  new
          services,  and  network  operators  must  enhance and  maintain  these
          increasingly  complex  infrastructures to support the broadening array
          of services.  For example, a single network operator's  infrastructure
          can include asynchronous  transfer mode (ATM), Internet protocol (IP),
          broadband  synchronous optical network (SONET),  frame relay, wireless
          cellular  and  personal  communication  service  (PCS),  and  internal
          signaling  and control  networks,  all of which must work  together to
          provide  reliable  and  efficient   service.   As  a  result  of  this
          proliferation    of    services,    individual    networks   and   the
          interconnections among networks have become considerably more complex.
          This increased  complexity  places a strain on network  management and
          control systems that incorporate multi-vendor equipment.

System Management Requirements

     Competition  among  existing  and  new  telecom  service   providers,   the
proliferation  of new  communications  services,  and pressure to provision  new
services quickly and  cost-effectively  has placed increased  demands on telecom
service  providers and equipment  manufacturers.  These demands have resulted in
the following system management requirements:

     o    Need  to  link  technology  and  customers.  Historically,  a  telecom
          company's  discrete  network  components and the broader  network have
          been managed  separately  from  service  activation  and  assurance of
          specific services to the handling of billing,  customer  service,  and
          other administrative  tasks. The introduction of a new service affects
          all  components  of  an  operator's  infrastructure.  For  example,  a
          customer desiring a temporary  800-number for a special event requires
          a network  operator to process the order and  activate  the service by
          providing special  instructions to the appropriate  network components
          (service  fulfillment),  monitor  the  network  and respond to traffic
          bottlenecks and unexpected service  interruptions or failures (service
          assurance),  and update billing,  accounting,  and marketing databases
          (customer care).

          In  response  to  increased  competition,  there is a greater  need to
          rapidly  introduce  new  services  and  respond  to  customer  service
          requests.  There is also an increased need to tighten the link between
          a telecom network's technology  components and service management (and
          ultimately  the  customer).   As  a  result,   new  network   software
          implementation  will increasingly  address specific business processes
          and  customer  service  requirements  rather than  network  technology
          requirements.  The implication to software and hardware vendors is the
          need to offer systems with proven  technical  and business  viability.
          Further,  telecommunications  service provider's  technology decisions
          are increasingly being led by marketing  personnel,  and include input
          from various business  functional areas throughout such companies.  As
          service  providers  focus more on customer care,  there will be a need
          for network  systems  designed to provide  management  more meaningful
          information with automated links from the customer  support  processes
          straight through to network and equipment management processes.

     o    Standardization   of   telecom   management   systems.    Competition,
          innovation,  and  profitability  are becoming the main drivers shaping
          the  investment  decisions of  communications  service  providers  and
          equipment  manufacturers in many parts of the world. Service providers
          are looking  for  solutions  that will not  require  them to lock into
          complex proprietary technologies or to be limited to a small number of
          equipment  suppliers.  Further,  as deregulation  enables companies to
          compete  on  a  more  global  scale,   communications   companies  are
          increasingly   seeking  to  standardize   network   architecture   and
          infrastructure (including hardware and software components) as well as
          business  practices.  



                                       2
<PAGE>


          As open,  distributed  computing  and industry  standards  continue to
          evolve,   hardware   and   software   vendors   will  need  to  supply
          communications  equipment  and  software  solutions  that  permit such
          standardization.

     o    New software  requirements.  The rapid  proliferation of communication
          services  and  networks  requires  highly  flexible  and  customizable
          management  and control  systems that can rapidly  respond to changing
          market and  infrastructure  conditions.  Commonly  called,  operations
          support  systems  ("OSS"),  these  systems  must  also  integrate  the
          increasing   number  of  network   elements   involved  in  any  given
          connection.   New  technology  must  enable  and  automate  the  rapid
          provisioning  of new  and  enhanced  services.  Increased  competition
          requires OSS solutions that enable  cost-effective  change  management
          and  offer  highly   reusable   technology  in  order  to  reduce  the
          time-to-market  for new or enhanced  services by taking  advantage  of
          past development work. Scalability is increasingly important since the
          rates of growth of new services and number of  subscribers  are highly
          variable  and  often  unpredictable.  Solutions  that  are not  highly
          scalable  may  not  be  adequate  for   mission-critical,   long-lived
          networks. The mission-critical  nature of public networks also demands
          solutions that are highly reliable. Software products that meet all of
          these  requirements are very complex,  and suppliers of these products
          must   increasingly   provide   highly   specialized   implementation,
          integration,  and customization  services in order to provide complete
          software  solutions.  The Company believes that few companies  possess
          both the industry expertise and software  development  capabilities to
          provide integrated solutions to the communications industry.

Product Portfolio Strategy

     TCSI  believes  that  its  future  success   depends   primarily  upon  the
development  and  enhancement  of OSS software  products that meet market needs.
Prior to 1996,  the  Company's  product  development  was  primarily  funded  by
customers as part of the  customized  development of software  applications  for
such  customers.  The Company  typically  retained  certain  rights to developed
software  products.  In certain  circumstances,  however,  the Company agreed to
restrict  its use of such  products to certain  markets and during  certain time
periods.  During 1996, the Company began funding a larger portion of its product
development  costs  internally.  During  1998 and 1997,  the  Company's  product
development   costs  totaled  $12.3  million  and  $5.9  million,   respectively
Customer-sponsored  product  development  costs were not material in 1998, 1997,
and 1996. The Company  intends to continue  internal  company-sponsored  product
development funding.

     During 1998,  the Company  continued to enhance its  development  platform,
SolutionCore,    and   to   develop   component-based    applications   software
(SolutionSuites)   used  to  automate   business   processes   for  a  range  of
communications   networks   and   services.    Through   internal   development,
key-licensing agreements,  strategic alliances and joint marketing arrangements,
the Company  intends to continue  investing  financial  resources in the ongoing
development of its product portfolio.

     In early 1997, the Company announced the integration of IONA  Technologies'
Orbix product into  SolutionCore.  The integration of this Object Request Broker
(ORB) product enables the Company's product line to be fully  interoperable with
the Common Object  Request  Broker  Architecture  ("CORBA")  2.0, a key industry
standard.

     In 1998,  the  Company  entered  into a  licensing  agreement  with ILOG to
incorporate ILOG JViews into SolutionCore.  ILOG JViews is incorporated into the
first release of TCSI's  Presentation  Services Package (PSP) for  SolutionCore.
ILOG's  visualization  expertise  will enable PSP  developers  to create  highly
graphical,   Java-based  user  interfaces   that   incorporate   two-dimensional
geographical  mapping  and  graphical   representations  of  customers'  network
topologies  and  architectures.  Later  in 1998,  the  Company  entered  into an
agreement  to  incorporate  Lumos'  Element  Access  Server  product  (EAS) into
SolutionCore.  The  Element  Access  Server  allows SNMP and  TL1-based  network
elements  (NEs) to be controlled  from clients  running in a CORBA  environment.
Integration of EAS into  SolutionCore  enables  TCSI's  customers to more easily
configure and manage their SNMP and TL1-based NEs.

     In these strategic  relationships,  the Company has agreed to pay a license
fee for sales of all  Company  products  that  contain the  integrated  software
products. The Company believes these strategic relationships are a key component
of its product strategy, and will continue to seek ways to integrate third-party
technology to enhance its products.

     During 1998, we also took the steps necessary to orient our  SolutionSuites
product  portfolio to match industry  standards and business  processes that are
common to all  service  providers.  Those  processes  are  service  fulfillment,
service  assurance,  and billing.  The Company  chose to focus  initially on the
assurance and fulfillment  processes,  and identified the critical  functions in
each process.  During 1998,  the Company  expanded its product  portfolio in the
assurance  and  fulfillment  process  areas as a result of the  following  three
agreements:

o    The  acquisition  of  GTE's  Network  Management  Organization  ("GTE-NMO")
     expanded   our  service   fulfillment   product   portfolio   by  providing
     applications for order entry and service  provisioning.  Their product, the
     WorldWin Suite, was built using SolutionCore, thus significantly increasing
     the  Company's  ability  to  integrate  it with other  TCSI  products.  The
     acquisition  also  provided us with a team of  engineers  with deep telecom
     knowledge and satisfied  emerging carrier market customers willing to serve
     as references.

o    A licensing agreement with NTT added  configuration  management and service
     activation  capabilities for data networks to our product portfolio.  NTT's
     product  was  developed  on  SolutionCore  by NTT and TCSI  engineers.  The
     product manages NTT's internal ATM networks, and the product is operational
     in multiple sites throughout Japan. The Company intends to integrate select
     components  with  provisioning  components  from  GTE-NMO to  provide  full
     flow-through service activation.

o    A  recent  marketing  alliance  with RTS  Software  Corporation  yielded  a
     solution that enables telecom service  providers to manage customer service
     agreements  and the field  technician  workforce.  The  Company  intends to
     integrate RTS products into  SolutionSuites  to enable service providers to
     link real-time network data to service level agreements,  thereby improving
     the service they provide to their customers.

Products and Services

     TCSI provides software  solutions and services that enable its customers to
minimize the costs and risks of developing and deploying  complex OSS within the
communications  industry.  Software licensing fees represented 26%, 14%, and 17%
of total  revenues  for the years  ended  December  31,  1998,  1997,  and 1996,
respectively.  Services  revenues  accounted  for  74%,  86%,  and 71% of  total
revenues for 1998, 1997, and 1996, respectively.

SolutionCore Product Line

     SolutionCore,   introduced  in  1997,  provides  sophisticated  application
development  modules  that can be used to  rapidly  build OSS for a  variety  of
network technologies. Components of SolutionCore are as follows:

     o    Object Services Package. The Object Services Package ("OSP") serves as
          the  foundation for TCSI's  SolutionCore  product line. OSP is a fifth
          generation  suite of advanced  middleware  and frameworks for building
          and  deploying  large,  business-critical  OSS for the  communications
          industry.  OSP enables application  development and customization time
          to be shortened;  enables  developers to better manage the building of
          large-scale,  distributed applications;  enables full interoperability
          with    Telecommunication's    Management    Network   ("TMN")   based
          applications; enables runtime changes, such as addition of application
          servers or changes to name server locations;  and integrates graphical
          user  interface,   business  application,  and  communication  layers,
          helping users improve quality and reduce operating costs.

     o    CORBA Services Package.  The CORBA Services Package (CSP) enables full
          interoperability between OSP and CORBA applications.

     o    TMN  Services  Package.  The  primary   international   standards  for
          communications  management  are  consolidated  in the  TMN  series  of
          recommendations from the International Telecommunications Union (ITU).
          TMN Services Package ("TSP") provides full TMN capabilities as part of
          the SolutionCore  communications management platform. TSP supports the
          integration  and  management  of  heterogeneous  networks and provides
          developers   with  a  



                                       4
<PAGE>


          suite of development tools and application programming interfaces that
          eliminates the complexities of the underlying infrastructure.

     o    Application  Templates Package.  Application  Templates Package (ATP),
          based  on  an   object-oriented,   reusable   framework  for  building
          large-scale communications  applications,  contains the templates that
          provide the basis for fault and event management  applications.  These
          features  allow  network  operators  to more  effectively  monitor the
          status  of their  networks,  providing  their  customers  with  better
          services  while  reducing  costs  for   development,   training,   and
          maintenance.   Product  features  also  manage  user  access  and  the
          administration of application servers.

     o    Presentation  Services  Package.  The  Presentation  Services  Package
          ("PSP") provides an integrated  Java-based  framework that reduces the
          time, effort, and cost required to develop sophisticated,  easy-to-use
          graphical user interfaces (GUI's) for SolutionCore. PSP allows the GUI
          developer to focus on satisfying the needs of their end-users, instead
          of building and maintaining integration code.

     o    Gateway  Services  Package.  In  addition  to  the  TMN  communication
          standards,  the  communications  industry  employs  a number  of other
          standards and protocols for managing network elements. Among these are
          the  Simple  Network  Management  Protocol  (SNMP),   widely  deployed
          worldwide  for managing IP devices  such as switches and routers;  the
          Transaction  Language 1 (TL1) and Man-Machine Language (MML) protocols
          for managing legacy  transmission  and other telecom  equipment in the
          United  States and the rest of the world,  respectively;  and  general
          text-based  protocols for managing  non-standard  compliant equipment.
          The Gateway Services Package (GSP) provides an easy to use toolkit for
          accessing network elements using these protocols.

SolutionSuites Product Line

     TCSI's  SolutionSuites  are families of configurable  application  products
that enable  telecom  service  providers to automate and improve their  business
processes for delivering  communication services. Each SolutionSuite is a family
of best-of-breed products that can be sold separately,  or bundled together into
an integrated process automation  solution.  These products combine  application
software  components that integrate and automate a broad range of communications
management  processes.  Such  products are  available  on a range of  platforms,
including UNIX and Windows NT servers,  and are accessible from workstations and
PCs.

     The  Company is  engaged  in the  process  of  continuously  enhancing  its
application  product  offerings in an effort to provide  customers with complete
solutions. The Company currently offers the following SolutionSuites:

     o    Service  Fulfillment  Suite.  The Service  Fulfillment  Suite provides
          flow-through service creation, from Order Entry, Provisioning (design)
          of the service,  and  Activation of the service in the network.  It is
          comprised  of  components  acquired  from GTE-NMO and from the license
          agreement with NTT.

     o    Service  Assurance  Suite.  The Service  Assurance  Suite  manages the
          reliability  of  communications  networks,  and  the  quality  of  the
          communications services provisioned on those networks, including Fault
          and Performance  Management,  Service Level Agreements,  and Workforce
          Management.  This suite includes  components provided in the marketing
          alliance with RTS Software,  developed  internally,  and acquired from
          GTE-NMO.

     o    WorldWin Suite.  The WorldWin Suite is the flagship product created by
          the GTE-NMO group  acquired from GTE by TCSI.  The WorldWin Suite is a
          complete OSS suite for emerging  communications  providers,  including
          Service Assurance,  Service Fulfillment,  and Billing interfaces.  The
          Company intends to market this product to the emerging  carrier market
          segment on a worldwide basis.

  SolutionServices

     The  Company  provides   implementation   services  to  develop  customized
solutions   based  on  its   SolutionCore   and   configuration   services   for
SolutionSuites products through its SolutionServices program. These services may
involve the


                                       5
<PAGE>


integration of the Company's  products with legacy systems and with the software
products of other  companies.  The Company  works with its customers to specify,
design,  develop,  and  deploy the  software  necessary  to meet its  customers'
business and operational  requirements.  The Company has extensive experience in
developing and implementing  solutions for the telecom industry in general,  and
network and element management  solutions in particular.  The Company engages in
careful planning of the development and deployment  phases, a formal development
process,  and rules or  conventions  that govern  every phase of  framework  and
application   development.   The  Company's  methods  combine   techniques  from
object-oriented  design and  development,  quality  management,  and distributed
systems  deployment,  and the Company's  solutions rely heavily on its products.
Due to the complex  requirements of its customer's network systems,  the Company
believes its  implementation  services  are a key factor in customer  purchasing
decisions.

     The Company is committed to responsive  user support and believes that such
support is critical in continuing  successful  long-term  relationships with its
customers.  The Company offers technical customer support from 8:00 a.m. to 5:00
p.m.  (Pacific  Standard Time), five days per week, which can be extended at the
customer's  option to 24 hours per day,  seven  days per week for an  additional
fee. Support is provided by telephone, via e-mail, via remote login, and on-site
as  necessary.  The  Company has  established  an  Internet  site that  provides
technical  information,  as well as schedules of the Company's upcoming training
courses.

     The Company conducts training courses for its customers, on a fee basis, at
the Company's  training  facilities in the States of California and  Washington,
and at customer sites. Training courses include instruction in the installation,
customization, and usage of SolutionCore and related products. Specifically, the
Company offers OSP, TSP, and WorldWin courses on a regular basis.

     As part of its software licensing  agreements,  the Company offers software
maintenance  contracts  to its  customers.  The  maintenance  contract  entitles
customers  to  telephone  support,  product  maintenance,  and upgrades to minor
product releases. Substantially all licensees of the Company's software products
were covered by a software  maintenance  contract during the year ended December
31, 1998.

Marketing and Sales

     The Company's  products are typically intended for use in applications that
may be critical to a customer's business.  Further, these applications are often
complex and require  significant  technical  knowledge of the Company's products
and the customer's operations to be successfully  deployed. To date, the Company
has primarily relied on its experienced worldwide direct sales force to sell its
products and related services.  The sales team also  significantly  utilizes the
Company's  engineering  personnel  to assist in product  demonstrations,  answer
customer questions, and determine system specifications.

     The Company  also uses other sales  channels to augment its product  sales.
Such channels  have  included  sales  representatives,  distributors,  equipment
manufacturers and systems integrators.  In the past, significant training on the
use  of  the   Company's   products   combined  with   extensive   knowledge  of
object-oriented  technology and its use in developing  advanced  telecom systems
was required to sell TCSI products.  Management believes that new sales channels
are an important part of the Company's growth strategy, as they will provide the
Company  with  access  to  important  new  customers  and  geographic   markets.
Management intends to continue to invest in channel development. Further, as the
Company continues to make enhancements to its products, management believes that
the Company's  products will be more  attractive to  third-party  developers and
resellers.

Customers

     The Company licenses its applications  development and runtime environment,
SolutionCore,  to  customers  around  the world.  The  following  chart  shows a
representative sample of the Company's 1998 customers:


                                       6

        *customer through OEM relationship with Siemens Business Systems

     To  date,  a  significant  portion  of  the  Company's  revenues  has  been
concentrated  among a limited  number of  customers.  In 1998,  1997,  and 1996,
revenues from the Company's five largest customers represented 74%, 64%, and 54%
of revenues,  respectively.  Further,  as a percentage of telecom revenues,  the
five largest  telecom  customers  represented  62% of revenues in 1996, the only
year  presented in which a portion of the Company's  revenues  were  non-telecom
revenues.  In 1998,  one customer  with  multiple  contracts,  NEC  Corporation,
represented   approximately  43%  of  total  revenues  and  Lucent  Technologies
represented approximately 11% of total revenues. The Company anticipates that it
will continue to experience significant customer concentration.

     The Company earns a significant portion of revenues from foreign customers.
Revenues outside of the United States accounted for approximately  70%, 78%, and
40% of the Company's total revenues for the years ended December 31, 1998, 1997,
and 1996,  respectively.  The Company expects that  international  revenues will
continue to account for a  significant  portion of its total  revenues in future
periods.

Competition

     The  Company  offers  products  and  services  in the  evolving  market for
telecommunications  OSS software.  Competition  in this market is intense and is
characterized by rapidly changing  technologies,  evolving  industry  standards,
changing regulatory requirements,  frequent new product introductions, and rapid
changes in  customer  requirements.  To maintain  and  improve  its  competitive
position, the Company must continue to develop,  acquire, license and introduce,
in a timely and  cost-effective  manner,  new  services,  products,  and product
features  that keep pace with  competitive  offerings by telecom  companies  and
independent software vendors. The principal competitive factors in the Company's
market are quality, performance,  price, customer support, corporate reputation,
and  product  features  such as  scalability,  interoperability,  functionality,
customizability, and ease of use.

     The Company faces  competition in each of the three  functional  areas that
the  Company  believes  are  necessary  for the  delivery  of  complete  network
management software solutions:  development environments,  turnkey applications,
and custom services. The Company's SolutionCore and SolutionSuites product lines
enable the Company to provide its customers  with both  application  development
software and telecom applications.  Because certain of the Company's competitors
focus only on one functional area of OSS software,  such competitors may be in a
position to develop  competitive  products  targeted  solely at the segment they
serve.

     These  competitors  include  major  communications  service  providers  and
equipment  and  computer  manufacturers,  each of which  may have  substantially
greater financial,  manufacturing,  technical, marketing, distribution and other
resources  than the  Company,  and may also have greater  name  recognition  and
longer-standing   relationships  with  customers  than  the  Company  may  have.
Furthermore,  many of the Company's current and potential customers continuously
evaluate  whether  to design,  develop,  and  support  internally  the  software
solutions provided by the Company, thereby obviating the customer's need to rely
on an outside  vendor such as the Company.  There can be no  assurance  that the
Company's current or potential  competitors will not develop products comparable
or superior to those  developed  by the Company or adapt more  quickly  than the
Company  to  new  technologies,   evolving  industry   standards,   new  product
introductions, or changing customer requirements.

Other Company Information

Backlog

     Orders for the  Company's  software  products and services are typically in
the form of  licensing  and service  contracts,  which call for the  delivery of
products and the  performance  of services  over a nine to twelve month  period.
Backlog  for the  Company's  products  and  services  represents  an estimate of
remaining   unearned  contract  value  for  all  signed   contracts,   including
unrecognized license fees, development service fees, and maintenance and support
fees.  Backlog  generally  does not include  any  potential  sublicense  fees or
royalties,  which are  recognized  as  earned.  Backlog  also  does not  include
expected future additions to contract value associated with existing  customers'
master license  agreements and service  contracts.  Because of variations in the
magnitude  and  duration  of orders  received  by the  Company,  and because the
Company's  contracts  may be canceled or  rescheduled  by the  customer  without
significant  penalty,  the Company's backlog at any particular date may not be a
meaningful indicator of future financial results. There can be no assurance that
such  TCSI's  customers  will in the future  continue  to place  orders with the
Company  which  equal or exceed  the  comparable  levels for prior  periods.  At
December 31, 1998, the Company's  backlog amounted to approximately $16 million.
At December 31, 1997, the Company's backlog was  approximately $20 million.  The
decline in backlog from 1997 to 1998 is  attributable  to a decline in bookings,
the  lengthy  sales  and  implementation  cycle  associated  with the  Company's
products, and the lack of channel development in Europe.

Employees

     At February 28, 1999, the Company had 305 employees, of which approximately
71% were professional  engineering  staff.  None of the Company's  employees are
represented  by a labor  union,  and the  Company has not  experienced  any work
stoppages. Management believes that the Company's employee relations are good.

     The Company's  future  success will depend to a  significant  extent on its
ability to continue to recruit and assimilate skilled engineers,  managers,  and
other personnel. The Company's future success will also depend on its ability to
attract  and  retain  qualified  managerial,  sales,  and  software  engineering
personnel.  The Company has at times  experienced  and  continues to  experience
difficulty in attracting  and retaining  qualified  personnel.  Competition  for
qualified  personnel  in the software  industry is intense,  and there can be no
assurance  that the Company will be successful in attracting  and retaining such
personnel.  The  complex  nature  of the  networks  of the  Company's  customers
requires that the Company  recruit and hire  personnel  with  expertise in and a
broad  understanding of the industries in which the Company's customers compete.
Furthermore,  competitors  have in the past  and may in the  future  attempt  to
recruit the  Company's  employees.  Failure to attract and retain key  personnel
could  have a  material  adverse  effect on the  Company's  business,  operating
results, and financial condition.

Intellectual Property

     The Company's  success and ability to compete is dependent in part upon its
proprietary software technology.  The Company relies on a combination of patent,
trade secret,  copyright and trademark laws, nondisclosure and other contractual
agreements, and technical measures to protect its proprietary rights. Currently,
the  Company  has seven  patents and two  applications  pending  for  additional
patents.  The Company expects to continue to file patent  applications  where it
believes it is appropriate to protect its proprietary technologies.

Executive Officers of the Company

The following are executive officers of the Company:

Item 2. Properties

     The  Company's  principal  administrative,  sales and  marketing,  customer
support, and product development facilities are located in Alameda,  California.
In addition,  the Company  leases sales  offices in Newmarket,  United  Kingdom;
Tokyo, Japan; and Raleigh, North Carolina, and product development facilities in
Bothell,  Washington  and  San  Jose,  California.  The  Company  currently  has
approximately  170,000  square feet of  facilities.  The  Company's  leases have
various  terms,  expiring at different  times through the year 2007. The Company
believes that its existing facilities are adequate to meet its current needs and
that suitable additional or alternative space will be available in the future on
commercially reasonable terms as needed.

Item 3. Legal Proceedings

     In November  1996,  a purported  class  action  complaint  was filed in the
Superior  Court  of the  State of  California,  Alameda  County,  by  Albert  J.
Copperstone and Joseph  Siciliano  against the Company,  certain of its officers
and directors,  and certain  underwriters (the "Copperstone State Action").  The
complaint in the Copperstone  State Action alleges that during a purported class
period of October 11, 1995 to September  25, 1996,  defendants  made  materially
false and misleading  statements concerning the Company's business condition and
prospects,  in violation of California  law. The  plaintiffs in the  Copperstone
State Action seek damages of an  unspecified  amount.  In July 1997,  plaintiffs
voluntarily  dismissed the underwriter  defendants  without  prejudice.  In June
1998,  plaintiffs  filed  their  second  amended  complaint.  In  January  1999,
defendants'  demurrers to that  complaint  were orally  overruled.  In response,
certain of the defendants filed answers to the second amended  complaint,  while
the remaining  defendants are awaiting the written order overruling  defendants'
demurrers.

     In November 1996, a purported  derivative action complaint was filed in the
Superior  Court of the State of  California,  Alameda  County,  by Mike  Tinkler
against the Company's Board of Directors and the Company as a nominal  defendant
(the  "Tinkler  Derivative  Action").  The  complaint in the Tinkler  Derivative
Action  also names the  Company as a nominal  defendant.  The  plaintiff  in the
Tinkler  Derivative  Action seeks damages of an unspecified  amount. In February
1998,  plaintiff filed a second amended  complaint  alleging breach of fiduciary
duties and violation of the  California  Corporations  Code.  In December  1998,
defendants answered the second amended complaint.

     In September  1997, a purported  class  action  complaint  was filed in the
United  States  District  Court  for the  Northern  District  of  California  by
Copperstone  and  Siciliano  against the Company and certain of its officers and
directors (the  "Copperstone  Federal Action").  The Copperstone  Federal Action
contains  virtually  identical  factual  allegations  as the  Copperstone  State
Action,  and alleges  violations of Sections  10(b) and 20(a) of the  Securities
Exchange  Act of 1934 and SEC Rule  10b-5.  The  plaintiffs  in the  Copperstone
Federal  Action also seek damages of an  unspecified  amount.  In January  1998,
defendants moved to dismiss the Copperstone  Federal Action.  In April 1998, the
Court  ordered  plaintiffs  to  certify a class  prior to ruling on  defendants'
motion to dismiss.  Plaintiffs  thereafter  provided  shareholders with a period
during  which they could choose to be excluded  from the class;  this period has
subsequently  expired.  In January 1999, the


                                       9
<PAGE>


court  dismissed  the  complaint  with leave to amend.  In  February  1999,  the
plaintiffs  moved  to stay  the  Copperstone  Federal  Action  in  favor  of the
Copperstone  State Action,  or for  additional  time in which to file an amended
complaint.  Defendants  have  requested  that the Court dismiss the  Copperstone
Federal  Action  with  prejudice.  Oral  argument on the  plaintiff's  motion is
scheduled for April 1999.

     No trial in any of these actions is scheduled.  The Company believes it has
meritorious defenses to all of these actions, and intends to defend each of them
vigorously.  The  Company is also a party as a  defendant  in various  lawsuits,
contractual  disputes,  and other  legal  claims,  the  results of which are not
presently determinable. In the opinion of management,  resolution of these legal
actions is not  expected  to have a  material  adverse  effect on the  financial
position  of the  Company.  However,  depending  on the  amount and  timing,  an
unfavorable  resolution  of any of these  matters  could  materially  affect the
Company's  financial  position,  results of operations,  or cash flows in future
periods.

     In 1997, Atmel Corporation ("Atmel") made a claim under the 1996 TCSI/Atmel
Corporation  Purchase  Agreement.  In 1998,  management  obtained  an  equitable
settlement  of this matter with the escrow agent  releasing  $550,000 (of a $1.0
million escrow fund) plus interest to TCSI, and the remaining $450,000 less fees
to Atmel. The settlement is reported as a nonrecurring  special gain in the 1998
consolidated statement of operations.

     The market price of the shares of common  stock has been,  and is likely to
continue to be,  highly  volatile and may be  significantly  affected by factors
such as actual or anticipated fluctuations in the Company's business,  operating
results,  and financial condition,  announcements of technological  innovations,
new products,  or new contracts of the Company or its competitors,  developments
with  respect  to  proprietary  rights,  adoption  of new  accounting  standards
affecting the software industry,  general market conditions,  and other factors.
In  addition,  the stock  market has from time to time  experienced  significant
price and volume fluctuations that have particularly  affected the market prices
for the common  stocks of  technology  companies.  These  types of broad  market
fluctuations  may  adversely  affect the market  price of the  Company's  common
stock.

     As of March 12, 1999, the number of shareholders of record of the Company's
common stock was 101 and the number of beneficial shareholders was approximately
4,500.  The Company has declared no cash dividends on its common stock since the
Company's  initial public offering.  The Company currently intends to retain any
earnings  for use in its  business  and  does  not  anticipate  paying  any cash
dividends in the foreseeable future.

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations

     In addition to historical  information  contained herein, this Management's
Discussion  and  Analysis  of  Financial  Condition  and  Results of  Operations
contains forward-looking  statements.  The forward-looking  statements contained
herein are subject to certain  factors that could cause actual results to differ
materially from those reflected in the forward-looking  statements. Such factors
include,  but are not limited to, those discussed  below under "Certain  Factors
That May Affect Future Results" and in Item 1 of this Form 10-K.

     Overview

     TCSI Corporation  ("TCSI" or the "Company")  provides  integrated  software
products and services for the global  telecommunications  ("telecom")  industry.
Since its inception in 1983, a significant portion of the Company's revenues has
been earned from telecom service  providers and equipment  manufacturers.  Since
its inception in 1983, a significant  portion of the Company's revenues has been
earned from telecom  service  providers  and equipment  manufacturers.  Prior to
1997,  the  Company  also  earned  revenues  from  licensing  embedded  software
contained in wireless  products and from the development of system solutions for
customers in the insurance,  health care, and transportation industries.  During
the second half of 1996, the Company  divested its non-telecom  product lines by
licensing  its  embedded  software  product  lines  and  terminating  its  final
transportation-related  development  agreement.  As a result,  since  1997,  the
Company  has focused  almost  entirely on  offering  software  solutions  to the
telecom industry.

     The Company provides services to customers under  level-of-effort and fixed
price contracts. Service revenues are recognized on the percentage-of-completion
method based on the  percentage of contract  costs incurred in relation to total
estimated contract costs. Changes to total estimated contract costs, if any, are
recognized in the period such changes are determined. The scope and size of many
of the Company's  system  solutions are large and complex,  typically  requiring
delivery over several quarters.  From  time-to-time,  customers have established
payment  milestones,  which can be achieved only after completion of the related
services.  Additionally,  a portion of the Company's  revenues has been,  and is
expected to continue to be, derived from software  licensing fees from a limited
number    of    customers.     The    Company    recognizes    revenues    under
time-and-material-type  contracts as the services are performed. For fixed-price
contracts,  the Company recognizes  revenues using the  percentage-of-completion
method. Additionally, the Company licenses software to customers under contracts
which do not require significant production,  modification,  or customization of
software.   The  Company  recognizes  revenues  under  these  contracts  when  a
noncancelable  license agreement has been signed,  the product has been shipped,
the  fees  are  fixed  and  determinable,   collectibility   is  probable,   and
vendor-specific  objective  evidence of fair value  exists to allocate the total
fee to elements of the arrangement.

     The  licensing  and  implementation  of  the  Company's  software  products
generally  involves  a  significant   commitment  of  resources  by  prospective
customers.  As a result,  the  Company's  sales  process  is  subject  to delays
associated with lengthy customer approval processes typically  accompanying such
significant  capital  expenditures.  Accordingly,  the Company is  substantially
dependent on its customers' decisions as to the timing and level of expenditures
and resource  commitments.  The  variability in the timing of such  expenditures
could cause material fluctuations in the Company's business,  operating results,
and financial  condition.  In this regard, the consistency of the Company's 1998
and 1997  quarterly  results  have  been  adversely  affected  by  delays in the
purchase of software licenses and related services.

     A substantial portion of the Company's revenues is derived from the sale of
the Company's  software products and services to major telecom service providers
and  equipment  manufacturers.  Due  to  the  complex  nature  of  the  advanced
Operations Support Systems ("OSS") software being developed, deployment of these
systems can contain significant technological risks. The Company has in the past
relied,  and will in the future  rely,  on its  development  and  implementation
expertise.  Additionally,  development and implementation of these systems often
occurs  over  several  quarters.  There  exists  the  risk  that a  change  in a
customer's  technology or business strategy during such lengthy  development and
implementation   periods   may  cause   early   termination   of  a  project  or
discontinuance of future phases. In this regard, the Company,  in limited cases,
has  experienced,  and may  continue to  experience,  fluctuations  in quarterly
revenues and operating results due to termination,  cancellation, or non-renewal
of agreements.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


     Management  believes that continued revenue growth is highly dependent upon
the  development  and  enhancement of software  products that meet market needs.
Prior to 1996,  the  Company's  product  development  was  primarily  funded  by
customers  as  part  of  the  development  of  software  applications  for  such
customers.  The Company typically  retained certain rights to developed software
products. In certain circumstances,  however, the Company agreed to restrict its
use of such products to certain markets and during certain time periods.  During
1996,  the Company  began  funding a larger  portion of its product  development
costs.  Although  management intends to target product  development  spending at
levels consistent with other software companies, from time-to-time, spending may
be greater or less than these amounts,  as circumstances  dictate.  Furthermore,
management expects that it may periodically  acquire  businesses,  products,  or
technologies to enhance the Company's current product offerings.

     The Company  generates  revenues from the sale of its software products and
related  services to the telecom  industry.  In 1998,  software  licensing  fees
represented  26% and  services  represented  74% of  total  revenues.  In  1997,
software  licensing fees  represented 14% and services  represented 86% of total
revenues.  In  1996,  software  licensing  fees  represented  17%  and  services
represented  71%  of  total  revenues.  Additionally,  1996  included  equipment
revenues  representing 12% of total revenues.  Software licensing fees increased
to $10.8 million in 1998, which reflects the Company's progress in transitioning
from a custom software services provider to a software product developer.

    For the years ended December 31, the revenue breakdown is as follows:

     Total revenues  increased 7% in 1998 to $42.3 million from $39.6 million in
1997.  The increase in revenues  for 1998 was  primarily  attributable  to a 92%
increase in software licensing fees to $10.8 million. License revenues primarily
improved as a result of completing  several major  projects in the United States
that were delayed in 1997 and the Company's focus on transitioning  from being a
custom software services provider to becoming a software product developer.  The
decrease in revenues  for 1997 versus 1996 was  attributable  to the  deployment
phase of a significant  agreement that the Company entered into during 1994 with
a non-telecom customer. In connection with this agreement, the Company purchased
equipment on behalf of the customer.  Excluding the  equipment  purchase,  total
telecom  revenues  decreased 9% to $39.0  million in 1997 from $42.9  million in
1996.  The  Company  expects  software  licensing  fees to continue to vary on a
quarterly and annual basis.

     Total  revenues  from  services  decreased 7% in 1998 to $31.6 million from
$34.0  million.  Total  revenues  from  services  decreased 20% in 1997 to $34.0
million  from $42.7  million  in 1996.  Total  telecom  revenues  from  services
decreased 6% in 1997 to $33.9 million from $36.2  million in 1996.  The downward
trend may continue  until the Company's  existing and future  customers  ramp up
their development efforts.

     Total software  licensing  revenues  increased 92% in 1998 to $10.8 million
from $5.6 million in 1997.  The increase was primarily due to the  completion of
several  major  projects in the United  States that were delayed in 1997 and the
Company's focus on transitioning  from being a custom software services provider
to becoming a software product developer.  Software licensing revenues decreased
45% in 1997 to $5.6 million from $10.2 million in 1996. The decline is primarily
the result of the  discontinuance  of  non-telecom  product  lines in late 1996.
Total telecom software  licensing revenues decreased 25% in 1997. The decline in
telecom software  licensing fees in 1997 is attributed to delays with our system
deployments  in North  America.  Prior  to 1998,  the  demand  centered  more on
follow-on services than on new licenses.  The Company expects software licensing
revenues to continue to vary on a quarterly and annual basis.

     For the years ended  December 31, the  percentage of revenues by geographic

     Telecom  revenues from the United States  increased 48% to $12.6 million in
1998.  The  increase  was the result of continued  relationships  with  existing
customers, particularly Lucent Technologies and the result of completing several
major  projects with our telecom  service  providers.  The 1997 increase was the
result of continued  relationships  with existing  customers,  particularly  NEC
Corporation,  resulting in revenues from follow-on  contracts signed in 1997. In
1997 and  1996,  revenue  decreased  as a result of  merger  activity  among the
Regional  Bell  Operating  Companies  (RBOC's)  that slowed the  decision-making
process. This also contributed to low bookings and delayed deployments. In 1998,
telecom revenue from the Asia-Pacific region continues to remain strong, roughly
the  same as  1997,  due to  continued  relationships  with  existing  customers
resulting in revenues from follow-on  contracts signed in 1997.  Telecom revenue
from Europe fell to 17% of total revenue for 1998 from 25% in 1997.  The decline
was  attributed  largely to slow  channel  development.  The  Company  generally
realizes  services  revenues  involving  design,   development,   testing,   and
deployment  over a twelve to eighteen  month  period.  The Company  expects that
international revenues will continue to account for a significant portion of its
total revenue in future periods.

     To date, a significant  portion of revenues has been  concentrated  among a
limited number of customers.  In 1998,  1997, and 1996,  total revenues from the
Company's  five  largest  telecom  customers  represented  74%,  64%, and 54% of
revenues,  respectively.  In 1998,  one customer  with multiple  contracts,  NEC
Corporation,   represented  approximately  43%  of  total  revenues  and  Lucent
Technologies,  represented  approximately  11% of total  revenues.  The  Company
anticipates   that  it  will   continue  to  experience   significant   customer
concentration.  There  can be no  assurance  that  such  customers  or any other
customers  will  continue to place  orders  with the Company  that will equal or
exceed the comparable levels for prior periods.

Costs of Services

     The Company  incurs direct costs in the  development  and deployment of its
customers' software solutions. The major components of direct costs are employee
compensation,  subcontractor  fees,  training  costs,  and other billable direct
costs,  including travel  expenses.  Direct costs also include an allocation for
benefits,   facilities,   telephone   expenses,   information  systems  support,
depreciation,  and amortization of intangibles. Costs of services declined 4% to
$20.3  million in 1998 from $21.1 million in 1997.  Costs of services  decreased
27% in 1997 from $28.8  million in 1996.  As a percentage  of service  revenues,
cost of services were 64%, 62%, and 67% for 1998, 1997, and 1996,  respectively.
The cost of service percentage for 1998 remained relatively  consistent with the
cost of service  percentage for 1997. Cost of services declined 4% while service
revenues declined 7% from 1997 levels. The cost of service percentage may remain
at or go below 1998 levels  until  existing and future  customers  ramp up their
development  efforts. In 1996, costs of services included increased  investments
in the completion of a number of North American telecom software solutions. Such
customer-related  investments  were  reduced in the first  half of 1997  thereby
contributing to lower direct costs of services in 1997. In addition, the decline
in cost  of  services  in 1997  compared  to  1996 is also  attributable  to the
divestiture of non-telecom business units in late 1996.

Product Development

     Product  development  includes employee  compensation,  subcontractor fees,
training costs, and other product  development  costs for existing and potential
new  software  products,  including  an  allocation  for  benefits,  facilities,
telephone  expenses,  information  systems support,  and depreciation.  Prior to
1996,  customers had primarily funded the Company's product  development as part
of the  development of software  applications.  As a result,  internally  funded
product development costs had not been material.  During 1996, the Company began
internally funding its product development costs.

     The  Company  invested  $12.3  million,  or 29%  of  revenues,  in  product
development  in 1998  compared to $5.9 million,  or 15% of revenues,  in product
development  in 1997. In 1996,  the Company  invested  $6.6  million,  or 11% of
revenues,  in product  development.  During 1998, product  development  spending
increased 108%,  reflecting the Company's continuing commitment to become a true
software  product  developer.  In December  1998,  TCSI  acquired  GTE's Network
Management   Organization   ("GTE-NMO")  which  provided  the  Company  with  an
established  customer base  (particularly in the emerging carrier segment) and a
new product development center in the Pacific Northwest.

     In 1996,  product  development  costs included telecom product  development
costs from two major upgrades of  SolutionCore  as well as  non-telecom  product
development costs from its divested business units. In 1997, the funds were used
primarily for enhancements made to SolutionCore. The Company expects to continue
to invest in Solution Core(R) as well as its new  component-based  applications,
SolutionSuites.  There can be no assurance,  however, that the Company's product
development spending will result in the successful introduction of new products.

Selling, General, and Administrative Expenses

     Selling  expenses  include  sales  and  marketing  employee   compensation,
promotional material, trade shows, travel, and facilities expenses.  General and
administrative   expenses  include   compensation  costs  related  to  executive
management,   finance,  and  administrative   personnel  along  with  the  other
administrative costs including recruiting, legal and accounting fees, insurance,
and bad debt expense.

     Selling,  general,  and  administrative  expenses  decreased  13% to  $16.2
million in 1998 from $18.6 million in 1997. Selling, general, and administrative
expenses  were $25.0  million in 1996.  The  decline was  primarily  due to cost
reduction efforts and an allocation of telephone and information systems support
expenses to the internal  users offset by one-time  payments in connection  with
the GTE-NMO acquisition.  In 1997, selling, general, and administrative expenses
decreased 26% from $25.0  million in 1996.  The decline was primarily due to the
discontinuance  of  non-telecom  business  units  in late  1996,  as well as the
Company's  business  realignment  decisions made during the past year.  Selling,
general,  and administrative  expenses as a percentage of revenue were 38%, 47%,
and 42% in 1998, 1997, and 1996, respectively. The increase in selling, general,
and  administrative  expenses as a  percentage  of revenues in 1997 is primarily
attributable  to the  decline in total  revenues  for the year  compared to 1996
total revenues.

Write-off of In-process Technology Acquired

     In  connection  with the  acquisition  of GTE-NMO,  the  Company  wrote off
approximately  $831,000 of in-process  technology acquired in the fourth quarter
of 1998 because the technology had not yet reached technological feasibility and
had no alternative future use.

Nonrecurring Special Items

     In 1998, the Company recorded a nonrecurring gain of $550,000 following the
settlement of litigation related to the sale of a non-telecom  business unit. In
1997,  the Company  concluded the sale of equipment  resulting in a nonrecurring
loss of $1.1 million.  In 1996, the Company recorded a nonrecurring gain of $7.9
million  related to the licensing of its embedded  wireless  technology to Atmel
Corporation  ("Atmel").  These gains and losses are described in further  detail
below.


                                       17
<PAGE>


Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


     In 1997, Atmel made a claim under the 1996 TCSI/Atmel  Corporation Purchase
Agreement.  In 1998,  management obtained an equitable settlement of this matter
with the escrow agent  releasing  $550,000 (of a $1.0 million  escrow fund) plus
interest to TCSI, and the remaining  $450,000 less fees to Atmel.  In the fourth
quarter of 1998, the Company recorded a nonrecurring gain of $550,000.

     The Company  incurred a charge to  operations  of $1.1 million in the first
two quarters of 1997 resulting from adjustments to the market-value of equipment
held for resale related to the termination of a  transportation  contract in the
third  quarter of 1996.  The Company  concluded the sale of the equipment in the
third quarter of 1997.  Related to this same agreement,  in the third quarter of
1996, the Company recorded a charge of  approximately  $3.3 million to cover the
costs  related to the  termination  of this  agreement.  The  customer  paid the
Company approximately $5.3 million to terminate the agreement.

     As part of the Company's strategy to focus on its core telecom  operations,
in November  1996,  the Company  licensed its embedded  wireless  technology and
related  product  lines to Atmel  Corporation  ("Atmel")  in exchange  for Atmel
common stock valued at $10.0 million. In the fourth quarter of 1996, the Company
recorded a gain on this licensing of its  technology,  net of transaction  costs
and project commitments,  totaling $7.9 million and a gain of approximately $0.6
million  from  the  sale of the  Atmel  stock  (described  as  "Gain  on sale of
investment in common stock" in the 1996 consolidated statement of operations).

Income Tax Provision (Benefit)

     TCSI  recorded an income tax provision  (benefit) of $1.1  million,  $(1.4)
million,  and $152,000 for 1998, 1997, and 1996 respectively.  The tax provision
for 1998 differed from the Federal  statutory  rate primarily due to a valuation
allowance recorded in the current year of $2.4 million.  The valuation allowance
was  provided  to  reduce  the net  deferred  tax  assets  to the  amount  which
management believes is recognizable,  based on the weight of available evidence,
on a more likely than not basis.

     At  December  31,  1998,  the  Company had  approximately  $3.7  million of
deferred tax assets, net of a valuation  allowance of $2.4 million.  Realization
of TCSI's net  deferred  tax assets is  dependent  upon the  Company  generating
sufficient taxable income in future years in appropriate jurisdictions to obtain
benefit from the reversal of temporary  differences  and from net operating loss
and tax  credit  carryforwards.  However,  the  amount of  deferred  tax  assets
considered realizable is subject to adjustment in future periods if estimates of
future  taxable income are reduced which would  negatively  impact the Company's
income tax provision in future periods.

Liquidity and Capital Resources

Operating Activities

     Net cash provided by operating  activities was $2.3 million,  $6.4 million,
and $6.9 million for the years 1998,  1997, and 1996,  respectively.  Cash flows
from  operating  activities  for  1998  primarily  reflected  a net loss of $4.5
million,  adjusted for depreciation and amortization of $4.1 million, a decrease
in receivables of $2.3 million,  a decrease in deferred revenue of $2.3 million,
and an increase in accounts  payable of $2.0 million.  Cash flows from operating
activities for 1997 primarily reflected a net loss of $2.6 million, adjusted for
depreciation and amortization of $4.2 million,  decreases in accounts payable of
$2.3  million and in accrued  liabilities  of $1.8  million,  and an increase in
deferred revenue of $2.7 million.  Cash flows from operating activities for 1996
primarily  reflected  net  income  of  approximately   $294,000,   adjusted  for
depreciation and amortization of $4.2 million,  and decreases in receivables and
income taxes payable of $4.1 million and $2.6 million, respectively.

     In the first  quarter of 1997,  1996  year-end  liabilities  related to the
buildout of the  Alameda  facility  in the first  quarter of 1997 were paid.  In
addition,  there was a decrease in accrued liabilities resulting from reductions
in bonus and  commission  payments in 1998 compared to 1997.  Other  significant
changes are the  decreases  in deferred  revenue and income taxes  payable.  The
decrease in deferred revenue from 1997 is primarily attributable to the decrease
in the volume

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

of  contracts  being  entered  into  that  incorporate  prepayments  and  to the
completion of several major projects.  The decrease in income taxes payable over
1997 is consistent with the refunds received during 1997.

Investing Activities

     Net cash used in investing activities was $15.0 million,  $6.7 million, and
$25.0  million for the years 1998,  1997,  and 1996,  respectively.  The Company
purchased  $40.3  million,  $21.6  million,  and  $35.9  million  of  marketable
securities in 1998,  1997, and 1996,  respectively,  while $35.6 million,  $21.6
million, and $19.3 million of marketable securities matured or were sold in each
respective  year.  During the year 1998,  the  Company  shifted a portion of its
investment  portfolio  into  longer-term  noncurrent  marketable  securities  in
anticipation  of the  predicted  decline in interest  rates.  In  addition,  the
Company  acquired  GTE-NMO;  this  contributed  to  decreases in cash flows from
investing  activities  of $6.5  million in 1998.  The net decrease in cash flows
from  investing  activities  also included $3.6 million of cash used for capital
expenditures  in  1998  compared  to  $7.2  million  of cash  used  for  capital
expenditures and leasehold  improvements  during 1997. The capital  expenditures
during  1997  are  primarily  related  to the  consolidation  of  the  Company's
facilities  in Northern  California  and to the  establishment  of the Company's
office  in the  United  Kingdom.  Management  expects  cash  used  in  investing
activities  will  continue to vary on a quarterly and annual basis and from time
to time, it may acquire  businesses,  products,  or  technologies to enhance the
Company's current product offerings.

Financing Activities

     Net cash provided by financing  activities was $1.6 million,  $3.3 million,
and $32.1 million for the years 1998, 1997, and 1996, respectively. The decrease
from 1997 to 1998 was  primarily  the  result  of a  decrease  in stock  options
exercised and stock purchased pursuant to the Employee Stock Purchase Plan which
is a function of market  conditions and investment  decisions made by employees.
The decrease from 1996 to 1997 was due to the fact that the Company raised funds
through a follow-on  public  offering,  realizing net proceeds of  approximately
$25.8  million.  In  addition,  in 1996,  cash flows from  financing  activities
included  $2.6 million of tax benefits  from stock  options;  there were no cash
flows from tax benefits of stock option in 1998 and 1997.

Additional Information on Liquidity and Capital Resources

     As of December  31,  1998,  the Company had cash and cash  equivalents  and
short-term  marketable  securities of $41.6 million.  The Company  believes that
existing cash balances  (including cash equivalents and marketable  securities),
together with existing sources of liquidity, including cash flows from operating
activities,  will provide  adequate cash to fund its operations for at least the
next  twelve  months.  The Company  also has  noncurrent  marketable  securities
totaling $7.3 million.  Over the past three years, the Company has satisfied its
liquidity  needs  principally  through  cash  flows from  operating  activities.
However, fluctuating receivable balances may affect the Company's operating cash
flows in the  future.  The  Company's  receivables  are  primarily  from  large,
credit-worthy customers in the telecommunications industry. The Company performs
ongoing  credit  evaluations  of its customers and does not require  collateral.
Allowances are maintained for potential credit losses. To date, such losses have
been within management's expectations.

     During 1998,  working capital decreased from $59.4 million in 1997 to $48.1
million.  The  decrease is  primarily  attributable  to the purchase of GTE-NMO.
During 1997, working capital increased $8.6 million to $59.4 million at December
31, 1997.  The increase is primarily due to the maturity of  approximately  $5.8
million of long-term  marketable  securities  that were reinvested in short-term
instruments and the receipt of approximately $3.6 million in income tax refunds.
Cash provided by financing  activities decreased $1.7 million to $1.6 million in
1998 compared to 1997.  Cash  provided by financing  activities  declined  $28.8
million to $3.3  million in 1997  compared to 1996.  In 1998 and 1997,  the cash
provided by  financing  activities  was  received as a result of the exercise of
employee stock options and the employee  stock  purchase plan. In addition,  the
Company  raised  approximately  $10.0 million from the licensing of its embedded
wireless software in late 1996.

     At December 31, 1998, the Company had no outstanding debt.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


Certain Factors That May Affect Future Results and Market Price of Stock

     Statements  in this report which are prefaced with words such as "expects,"
"anticipates,"  "believes"  and similar  words and other  statements  of similar
sense,  are  forward-looking  statements.  These  statements  are  based  on the
Company's  current  expectations  and  estimates  as to  prospective  events and
circumstances  which may or may not be within the  Company's  control  and as to
which there can be no firm assurances given. These  forward-looking  statements,
like any other forward-looking statements,  involve risks and uncertainties that
could  cause  actual  results  to differ  materially  from  those  projected  or
anticipated.  The following discussion  highlights some of the risks the Company
faces.

Potential Fluctuations in Future Operating Results

     The  Company  has   experienced  and  expects  to  continue  to  experience
significant  fluctuations in revenues and operating results on a quarterly or an
annual  basis as a result of a number of  factors,  many of which are beyond the
control of the Company. These factors include the cancellation, modification, or
non-renewal of service, license, or maintenance agreements;  the size and timing
of significant customer engagements and license fees; the relative proportion of
services  and software  licensing  fees;  personnel  changes;  capital  spending
patterns of the Company's  customers;  concentration of the Company's customers;
the lengthy  sales  cycles of the  Company's  products  and  services;  industry
acceptance  of  the  Company's  products  and  services;  changes  in  operating
expenses;  new product  introductions and product enhancements by the Company or
its competitors;  the ability of the Company to develop,  introduce,  and market
new  products and product  enhancements  on a timely  basis;  changes in pricing
policies  by  the  Company  or its  competitors;  regulatory  changes,  currency
fluctuations,  and general  economic  factors.  These  factors are  difficult to
forecast, and these or other factors could have a material adverse effect on the
Company's business, operating results, and financial condition.

     Historically,  a portion of the  Company's  revenue has been  derived  from
software  licensing fees from a limited number of customers.  Variability in the
timing of such  license  fees has caused,  and may  continue to cause,  material
fluctuations  in  the  Company's  business,  operating  results,  and  financial
condition.  The Company's  products and services  generally require  significant
capital  expenditures  by  customers as well as the  commitment  of resources to
implement,  monitor,  and  test  the  Company's  enhancements  to such  systems.
Accordingly,  the Company is substantially dependent on its customers' decisions
as to the timing and level of such expenditures and resource commitments.

     In  addition,  the  Company  typically  realizes a  significant  portion of
license revenues in the last weeks or even days of a quarter.  As a result,  the
magnitude of quarterly  fluctuations  may not become  evident  until late in, or
after the close of, a particular  quarter.  The Company's  expenses are based in
part on the Company's  expectations  as to future  revenue levels and to a large
extent are fixed in the short-term.  If revenues do not meet  expectations,  the
Company's business,  operating results, and financial condition are likely to be
materially  adversely affected.  In particular,  because only a small portion of
the  Company's  expenses  varies with  revenues,  results of  operations  may be
disproportionately affected by a reduction in revenues. As a result, the Company
believes that  period-to-period  comparisons  of its  operating  results are not
necessarily  meaningful  and should not be relied upon as  indications of future
performance.

Lengthy Sales and Implementation Cycles

     The Company's  products are typically intended for use in applications that
may be critical to a customer's  business.  The licensing and  implementation of
the Company's software products  generally involves a significant  commitment of
resources by prospective customers.  As a result, the Company's sales process is
often  subject  to  delays  associated  with  lengthy  approval  processes  that
typically  accompany  significant  capital  expenditures.  For  these  and other
reasons,  the  sales  cycles  associated  with the  licensing  of the  Company's
products are often lengthy (historically  averaging approximately nine to twelve
months) and subject to a number of significant delays over which the Company has
little or no control.  In  addition,  the  Company  does not  recognize  service
revenues  until the services are  rendered.  The time  required to implement the
Company's products can vary significantly with the needs of its customers and is
generally  a  process  that  extends  for  several  months.   Because  of  their
complexity,  larger implementations may take multiple quarters to complete. From
time to time,  the Company has  provided  services to  implement  certain  large
projects,  and,  although no contractual basis exists for the customer to do so,
certain  customers have delayed payment of a portion of service fees and in some
cases have disputed the fees charged. There can be no assurance the Company will
not experience  additional


                                       20
<PAGE>


Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


delays or disputes regarding payment in the future,  particularly if the Company
receives  orders  for  large,  complex  installations.  Therefore,  the  Company
believes that its quarterly and annual operating results and financial condition
are likely to vary significantly in the future.

Acceptance of the Company's Products; Product Development Risks

     A substantial  portion of the Company's  revenues are derived from the sale
of the Company's  component-based  software  products and services which provide
software  solutions to major  corporations in the worldwide telecom services and
equipment  industries.   Although  many  telecom  companies  currently  seek  to
integrate their business operation systems and network operation systems,  there
can be no assurance that these or other service  providers will continue to seek
the  integration  of such systems or that such  companies will use the Company's
products.  Due to the complex nature of the advanced  operations support systems
("OSS") developed by the Company,  the Company has in the past relied,  and will
in the future continue to rely, on its development and implementation expertise.
The Company continues to develop software products that reduce the customization
necessary to fully  integrate  customers'  systems.  There can be no  assurance,
however,  that the Company will continue to successfully develop and market such
products  or, even if  successful,  that the  revenue  from such  products  will
compensate for any concurrent  loss of development  and  implementation  service
revenues.  The  failure by the Company to  successfully  develop and market such
products and technologies  would have a material adverse effect on its business,
operating results, and financial condition.

     Revenues  attributable  to the Company's  products and services have in the
past  accounted  for, and are expected to continue to account for, a substantial
majority of the Company's revenues.  Accordingly, the Company's future business,
operating results, and financial condition are significantly  dependent upon the
continued market acceptance of its portfolio of products and services. There can
be no assurance  that the Company's  technology  will continue to achieve market
acceptance or that the Company will be successful in developing, introducing, or
marketing   improvements   to  its  products.   Moreover,   the  life  cycle  of
component-based  products  is  difficult  to  estimate  due in large part to the
recent   changes  in  the  telecom   markets,   the  effect  of  future  product
enhancements,  and  competition.  A  decline  in the  demand  for the  Company's
software as a result of new or existing competing  technologies or other factors
would  have a  material  adverse  effect on the  Company's  business,  operating
results,  and  financial   condition.   Management  intends  to  target  product
development spending at amounts consistent with other software companies.  There
can be no assurance,  however,  that such funding will result in the  successful
introduction of new products.

Customer Concentration

     To  date,  a  significant  portion  of  the  Company's  revenues  has  been
concentrated  among a limited  number of customers.  In  particular,  in 1998, a
large portion of revenues was derived from contracts  negotiated through a large
equipment  manufacturer  in Asia.  While  the  economic  crisis  in Asia has not
materially  adversely  affected the Company,  there can be no assurance  that it
will not do so in the future. In addition,  the Company anticipates that it will
continue  to  experience  significant  customer  concentration.  There can be no
assurance that such customers or any other customers will in the future continue
to place orders with the Company which equal or exceed the comparable levels for
prior periods.  In addition,  the Company's  customers  typically  designate one
individual to procure network  management  software.  If any of such individuals
were terminated,  transferred,  or replaced,  the Company would be vulnerable to
cancellation  of an  order  if,  for  example,  the  Company's  competitors  had
preexisting  relationships  with such individual's  replacement.  As a result of
these  factors,  the  Company's  business,   operating  results,  and  financial
condition could be materially adversely affected.

Product Defects

     The Company provides complex software  products for major telecom equipment
manufacturers,  systems integrators,  and service providers. The development and
enhancement  of such  complex  software  entails  substantial  risks of  product
defects.  The Company has in the past identified  software defects in certain of
its  products.  There  can be no  assurance  that  errors  will  not be found in
existing or new products or releases after commencement of commercial licensing,
which may result in delay or loss of revenue,  loss of market share,  failure to
achieve  market  acceptance,  or may  otherwise  adversely  impact the Company's
business, operating results, and financial condition.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


Implementation Risks

     As is  characteristic  of  companies  providing  software  solutions to the
telecom  industry,  the  complexities  involved in  implementing  the  Company's
software  solutions entail risks of performance  shortfalls.  From time to time,
the Company has agreed to accept some financial  responsibility,  in the form of
negotiated   penalty  amounts,   when  the  Company's   products  did  not  meet
specifications  or caused  customer system  downtime.  There can be no assurance
that the Company will not encounter similar delays or other  difficulties due to
such implementation  complexities in the future.  Because the Company's customer
base consists of a relatively  limited number of customers,  the product defects
or  implementation  errors  would  be  potentially  damaging  to  the  Company's
reputation.  Any such occurrence  could have a material  adverse effect upon the
Company's business, operating results, and financial condition.

International Sales

     Revenues outside of North America  accounted for 70% of the Company's total
revenues  for the year  ended  December  31,  1998.  The  Company  expects  that
international revenues will continue to account for a significant portion of its
total revenue in future  periods.  The Company  intends to penetrate  additional
international   markets  and  to  further  expand  its  existing   international
operations.  The Company's  international business involves a number of inherent
risks,  including  greater  difficulty in accounts  receivable  collection  and,
therefore, longer accounts receivable collection periods; difficulty in staffing
and  managing  foreign  operations;  a longer  sales  cycle  than with  domestic
customers;  potentially  unstable  political and economic  conditions;  language
barriers;  cultural  differences  in  the  conduct  of  business;   seasonality;
unexpected changes in regulatory requirements,  including a slowdown in the rate
of  privatization  of  telecom  service   providers;   reduced   protection  for
intellectual  property  rights  in  some  countries;   potentially  adverse  tax
consequences;  and tariffs  and other trade  barriers.  In  addition,  while the
recent  economic  crisis  in Asia  has not  materially  adversely  affected  the
Company,  there can be no assurance that it will not do so in the future.  Also,
access  to  foreign   markets  is  often   difficult  due  to  the   established
relationships  between government owned or controlled  communications  companies
and local suppliers of  communications  products.  There can be no assurance the
Company  will  be  able to  successfully  penetrate  such  foreign  markets.  In
addition,  there can be no assurance that the Company will be able to sustain or
increase revenue derived from  international  licensing and services or that the
foregoing  factors  will not have a  material  adverse  effect on the  Company's
future  international  business,  and consequently,  on the Company's  business,
operating results, and financial condition.

     International   sales  also   entail   risks   associated   with   currency
fluctuations.  The Company has attempted to reduce the risk of  fluctuations  in
currency  exchange rates  associated with  international  revenue by pricing its
products and services in United States dollars whenever  possible.  The Company,
however,  generally pays the expenses of its  international  operations in local
currencies  and does not engage in  hedging  transactions  with  respect to such
obligations.  Upward  fluctuations  in currency  exchange  rates could cause the
Company's  products to become  relatively  more expensive to foreign  customers,
leading  to  a  reduction  in  sales  or  profitability.   Furthermore,   future
international activity may result in foreign currency denominated sales, and, in
such  event,  gains and losses on the  conversion  to U.S.  dollars of  accounts
receivable  and accounts  payable  arising  from  international  operations  may
contribute to fluctuations in the Company's operating results.

Dependence on Telecommunications Carriers; Government Regulation

     Many of the Company's principal customers are major telecom carriers.  Such
companies operate within the telecom industry,  which has been  characterized by
intense  competition  in the  development  of  new  technology,  equipment,  and
customer services.  The Company believes that large telecom carriers have become
increasingly cautious in making significant capital expenditures, due in part to
increased  competition from smaller,  rapidly developing  alternative  carriers,
decreasing  prices for telecom  services  and  equipment,  and  regulatory  rate
structures  that have become less  dependent on the level of  carriers'  capital
expenditures.  These and other  factors  have in the past and may in the  future
cause  such  customers  to  experience   significant   fluctuations  in  capital
expenditures for OSS software.

<PAGE>


Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


     The  telecom  industry  is subject to  extensive  regulation  in the United
States and other countries,  and the Company's  customers generally must receive
regulatory  approvals  in  conducting  their  businesses.  Although  the telecom
industry has been characterized by government  deregulation and  liberalization,
there can be no assurance  that such trends will  continue or that  reregulation
will not occur.  Government regulatory policies are likely to continue to have a
major  impact on the  Company's  ability to attract  and retain  customers.  For
example,  regulatory  authorities may continue to oversee the pricing of new and
existing  telecom  services;  and the  pricing  may, in turn,  impact  carriers'
ability to make  significant  capital  expenditures.  The  enactment by federal,
state,  or  foreign  governments  of new laws or  regulations  or  change in the
interpretation  of existing  regulations  could  adversely  affect the Company's
customers,  and thereby affect the Company's  business,  operating results,  and
financial condition.

Competition

     The  Company  offers  products  and  services  in the  evolving  market for
telecommunications  OSS software.  Competition  in this market is intense and is
characterized by rapidly changing  technologies,  evolving  industry  standards,
changing regulatory requirements,  frequent new product introductions, and rapid
changes in  customer  requirements.  To maintain  and  improve  its  competitive
position, the Company must continue to develop,  acquire, license and introduce,
in a timely and  cost-effective  manner,  new  services,  products,  and product
features  that keep pace with  competitive  offerings by telecom  companies  and
independent software vendors. The principal competitive factors in the Company's
market are quality, performance,  price, customer support, corporate reputation,
and  product  features  such as  scalability,  interoperability,  functionality,
customizability, and ease of use.

     The Company faces  competition in each of the three  functional  areas that
the  Company  believes  are  necessary  for the  delivery  of  complete  network
management software solutions:  development environments,  turnkey applications,
and custom services. The Company's SolutionCore and SolutionSuites product lines
enable the Company to provide its customers  with both  application  development
software and telecom applications.  Because certain of the Company's competitors
focus only on one functional area of OSS software,  such competitors may be in a
position to develop  competitive  products  targeted  solely at the segment they
serve.

     These  competitors  include  major  communications  service  providers  and
equipment  and  computer  manufacturers,  each of which  may have  substantially
greater financial,  manufacturing,  technical, marketing, distribution and other
resources  than the  Company,  and may also have greater  name  recognition  and
longer-standing   relationships  with  customers  than  the  Company  may  have.
Furthermore,  many of the Company's current and potential customers continuously
evaluate  whether  to design,  develop,  and  support  internally  the  software
solutions provided by the Company, thereby obviating the customer's need to rely
on an outside  vendor such as the Company.  There can be no  assurance  that the
Company's current or potential  competitors will not develop products comparable
or superior to those  developed  by the Company or adapt more  quickly  than the
Company  to  new  technologies,   evolving  industry   standards,   new  product
introductions, or changing customer requirements.

Rapid Technological Change; Need to Manage Product Transitions

     The market for the Company's  products is characterized by rapidly changing
technologies,  evolving industry standards,  changing  regulatory  environments,
frequent new product introductions,  and rapid changes in customer requirements.
The introduction of products embodying new technologies and the emergence of new
industry  standards  and  practices can render  existing  products  obsolete and
unmarketable.  As a  result,  the life  cycles  of the  Company's  products  are
difficult to estimate.  This poses substantial risks for the Company because the
Company's products and software solutions typically have lengthy development and
sales cycles. The Company's future success will depend on its ability to enhance
its  existing   products  and  to  develop  and  introduce,   on  a  timely  and
cost-effective  basis,  new  products and product  features  that keep pace with
technological  developments  and  emerging  industry  standards  and address the
evolving needs of its customers. There can be no assurance that the Company will
be successful in developing and marketing new products or product  features that
respond to technological change or evolving industry standards, that the Company
will not  experience  difficulties  that could delay or prevent  the  successful
development,  introduction, and marketing of these new products and features, or
that its new products or product  features will adequately meet the requirements
of the

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


marketplace  and  achieve  market  acceptance.  If the  Company is  unable,  for
technological  or other  reasons,  to  develop  and  introduce  enhancements  of
existing  products or new products in a timely manner,  the Company's  business,
operating  results,   and  financial  condition  will  be  materially  adversely
affected.

     The Company's products are designed to operate on a variety of hardware and
software  platforms and with a variety of databases employed by its customers in
their networks.  The Company must continually modify and enhance its products to
keep  pace  with  changes  in  hardware  and  software  platforms  and  database
technology.  As a result,  uncertainties related to the timing and nature of new
product  announcements and introductions or modifications by systems vendors and
by vendors of relational database software could materially adversely impact the
Company's business, operating results, and financial condition. In addition, the
failure of the  Company's  products to operate  across the various  existing and
evolving versions of hardware and software  platforms and database  environments
employed by  consumers  would have a material  adverse  effect on the  Company's
business, operating results, and financial condition.

     The  introduction or announcement of products by the Company or one or more
of its competitors embodying new technologies,  or changes in industry standards
or customer  requirements,  could  render the  Company's  software  products and
solutions obsolete or unmarketable. The introduction of new or enhanced versions
of its  products  requires  the  Company  to manage  the  transition  from older
products in order to minimize  disruption in customer ordering.  There can be no
assurance that the introduction or announcement of new product  offerings by the
Company  or one or more of its  competitors  will not cause  customers  to defer
licensing of existing Company products or engaging the Company's  services.  Any
deferral of license or service  revenues could have a material adverse effect on
the Company's business, operating results, and financial condition.

Protection of Intellectual Property

     The Company's  success and ability to compete is dependent in part upon its
proprietary software technology.  The Company relies on a combination of patent,
trade secret,  copyright and trademark laws, nondisclosure and other contractual
agreements,  and technical measures to protect its proprietary  rights. To date,
the Company has patents and patents pending related to its telecom products. The
Company expects to continue to file patent  applications where it believes it is
appropriate  to protect its  proprietary  technologies.  Despite  the  Company's
efforts to protect its proprietary rights,  unauthorized  parties may attempt to
copy aspects of the Company's products or to obtain and use information that the
Company regards as  proprietary.  There can be no assurance that the steps taken
by  the   Company  to  protect   its   proprietary   technology   will   prevent
misappropriation of such technology, and such steps may not preclude competitors
from developing products with functionality or features similar to the Company's
products. In addition, effective patent, copyright,  trademark, and trade secret
protection  may be  unavailable  or limited in certain  foreign  countries.  The
failure of the  Company  to protect  its  proprietary  information  could have a
material  adverse  effect on the  Company's  business,  operating  results,  and
financial condition.

     While the Company  believes that its products and  trademarks and their use
by customers  does not infringe upon the  proprietary  rights of third  parties,
there  can  be  no  assurance   that  the  Company   will  not  receive   future
communications from third parties asserting that the Company's products or their
use by customers infringe, or may infringe, the proprietary rights of such third
parties.   The  Company  expects  that  software  product   developers  will  be
increasingly  subject to  infringement  claims as the  numbers of  products  and
competitors in the Company's  industry  segment grows and the  functionality  of
products in different  industry segments  overlaps.  Any such claims,  including
meritless  claims,  could  result  in  costly,  time-consuming  litigation,  and
diversion of technical and  management  personnel.  In the event any third party
was to make a valid claim and a license was not made  available on  commercially
reasonable  terms,  or if the  Company  was  unable  to  develop  non-infringing
alternative technology, the Company's business, operating results, and financial
condition could be materially adversely affected.

     In  addition,  certain of the  Company's  customers  regard  the  solutions
provided by the Company to be  proprietary  to such customers and may attempt to
prohibit  the Company  from using or  otherwise  benefiting  from certain of the
advances  made in developing  such  solutions.  Although the Company  intends to
increasingly   standardize  its  integration   solutions   through  the  use  of
component-based   software  products,   there  can  be  no  assurance  that  the
prohibition or restrictions


                                       24

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


imposed by certain  customers on the use of certain  intellectual  property will
not adversely affect the Company's  business,  operating results,  and financial
condition.

     The Company relies on certain software that it licenses from third parties,
including  software that is integrated  with internally  developed  software and
used in the  Company's  products  to  perform  key  functions.  There  can be no
assurance that these third-party software licenses will continue to be available
to the Company on commercially  reasonable  terms or that such licenses will not
be  terminated.  Although  the Company  believes  that  alternative  software is
available from other third-party suppliers, the loss of or inability to maintain
any of these software  licenses or the inability of the third parties to enhance
their products in a timely and  cost-effective  manner could result in delays or
reductions in product  shipments by the Company until equivalent  software could
be developed  internally or identified,  licensed,  and integrated,  which would
have a material adverse effect on the Company's business, operating results, and
financial condition.

Dependence on Key Personnel

     The Company's future growth and success depends to a significant  extent on
its ability to attract and retain  qualified  managerial,  sales,  and  software
engineering  personnel.  The Company has at times  experienced  and continues to
experience  difficulty in  attracting  and retaining  qualified  personnel.  The
Company's  future  success  will also  depend on the  ability of its current and
future management personnel to operate effectively,  both independently and as a
group. The Company has recently experienced changes in its executive management.
For example,  in November  1998,  the Company  appointed a new Vice President of
Marketing. Competition for the hiring of such personnel in the software industry
is intense, and there can be no assurance that the Company will be successful in
locating  candidates  with  appropriate  qualifications.  Failure to attract and
retain  key  personnel  could have a material  adverse  effect on the  Company's
business, operating results, and financial condition.

Risks Associated with Acquisitions

     The Company periodically  evaluates potential acquisitions of complementary
businesses, products, and technologies. To support its growth plans, the Company
may acquire companies that have a significant installed base of products not yet
offered  by the  Company,  have  strategic  distribution  channels  or  customer
relationships,  or otherwise  present  opportunities  which management  believes
enhance the Company's competitive  position.  For example, in December 1998, the
Company acquired GTE-NMO. This provided the Company with an established customer
base, particularly in the emerging carrier segment and a new product development
center in the Pacific Northwest.

     Such  acquisitions  could subject the Company to numerous risks,  including
risks  associated  with the  integration  into the Company of new  employees and
technology.  Moreover,  the  negotiation  and  acquisition of such  transactions
involve the diversion of substantial  management resources and the evaluation of
such   opportunities   requires   substantial   diversion  of  engineering   and
technological resources. In addition, transactions involving the issuance by the
Company  of common  stock or other  securities  could  result in  immediate  and
substantial  dilution to the Company's  existing  shareholders,  large  one-time
write-offs,  or the creation of goodwill or other  intangible  assets that could
result  in  amortization   expenses.   The  failure  to  successfully  evaluate,
negotiate,  and effect acquisition  transactions,  could have a material adverse
effect on the Company's business, operating results, and financial condition.

Volatility of Stock Price

     The market price of the shares of the  Company's  common stock has been and
is likely to continue to be highly volatile and may be significantly affected by
factors such as actual or anticipated  fluctuations  in the Company's  business,
operating  results,  and financial  condition;  announcements  of  technological
innovations,  new products,  or new contracts by the Company or its competitors;
developments  with respect to  proprietary  rights;  adoption of new  accounting
standards affecting the software industry;  general market conditions; and other
factors.  In  addition,  the stock  market has,  from time to time,  experienced
significant price and volume  fluctuations  that have particularly  affected the
market  prices  for  technology  company  stocks.  These  types of broad  market
fluctuations  may  adversely  affect the market  price of the  Company's  common
stock.  In the past,  following  periods of  volatility in the market price of a
company's  securities,

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations (Continued)


securities  class  action  litigation  has often  been  initiated  against  such
company.  Such litigation  could result in substantial  costs and a diversion of
management's attention and resources, which could have a material adverse effect
upon the Company's business, operating results, and financial condition. In this
regard,  in late  1996,  two  lawsuits  on behalf of  certain  of the  Company's
shareholders  were filed  against the Company  and various of its  officers  and
directors.  In late  September  1997, a class  action  lawsuit was filed in U.S.
Federal Court on behalf of certain  shareholders against the Company and various
of its officers and  directors.  The state  actions  allege  violations of state
securities laws during 1995 and 1996, and the federal action alleges  violations
of the federal securities laws. The Company believes it has meritorious defenses
to all of these  actions and intends to defend each of them  vigorously.  In the
opinion of management, resolution of these legal actions is not expected to have
a material  adverse  effect on the financial  position of the Company.  However,
depending on the amount and timing,  an  unfavorable  resolution of any of these
matters could  materially  affect the Company's  future results of operations or
cash flows in a particular period.

Year 2000 Compliance

     Many currently  installed  computer systems and software products are coded
to accept only two-digit  entries in the date code field.  Beginning in the year
2000,  these  date  code  fields  will  need to  accept  four-digit  entries  to
distinguish  21st century dates from 20th century  dates.  As a result,  in less
than one year,  computer systems and software used by many companies may need to
be upgraded to comply with such "Year  2000"  requirements.  In early 1998,  the
Company  developed  procedures  for  evaluating and managing the risks and costs
associated  with Year 2000 problems.  TCSI believes it is devoting the necessary
resources to identify  and modify its systems and products  impacted by the Year
2000  problem and to implement  new systems and release new product  versions to
become Year 2000  compliant in a timely  manner.  The Company has  concluded its
assessment of the Year 2000 issues and has determined  that the  consequences of
its Year 2000 issues will not have a material effect on its business, results of
operations, or financial conditions.  The Company believes its products are Year
2000 compliant.

     The Company  believes that its costs  associated  with  implementing  these
procedures will not have a material  adverse effect on the results of operations
or financial condition of the Company.  However,  there can be no assurance that
unexpected  delays or increased costs  associated with  implementation  will not
have an adverse effect on the Company's operations. In addition, there can be no
assurance that the Company's  software  contains all date code changes necessary
to prevent  processing errors  potentially  arising from calculations  using the
Year 2000 date. Any  disruptions in product  development or other  operations of
the Company as a result of Year 2000  noncompliance  would materially  adversely
affect the Company's business, financial condition and results of operations.

     TCSI  believes  that the  purchasing  patterns of customers  and  potential
customers  may  also be  affected  by  Year  2000  issues  as  companies  expend
significant  resources to upgrade their current  software  systems for Year 2000
compliance. These expenditures may result in reduced funds available to purchase
products  such as those  offered by the  Company.  Furthermore,  there can be no
assurance  that the  Company's  customers and suppliers are or will be Year 2000
compliant.  Failure of the Company's customers and suppliers to address the Year
2000 issues at all,  sufficiently,  or in a timely manner, could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

     Interest  Rate Risk.  As of  December  31,  1998,  the  Company's  cash and
investment  portfolio  includes  fixed-income  securities.  These securities are
subject  to  interest  rate risk and will  decline  in value if  interest  rates
increase.  Due to the short duration of the Company's investment  portfolio,  an
immediate  10% increase or decrease in interest  rates would not have a material
effect on the fair market value of the Company's portfolio.  The Company has the
ability to hold its fixed income  investments until maturity,  and therefore the
Company would not expect its  operating  results or cash flows to be affected to
any significant degree by the effect of a sudden change in market interest rates
in its investment portfolio.

     Foreign Currency Exchange Risk. The majority of the Company's  revenues are
denominated in U.S. dollars and, as a result,  the Company has relatively little
exposure to foreign currency  exchange risk. The Company does not use derivative
financial instruments for trading or speculative purposes.

Part IV, Item 14(a)(1) and (2).

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Shareholders
TCSI Corporation

     We have  audited  the  accompanying  consolidated  balance  sheets  of TCSI
Corporation  as of  December  31, 1998 and 1997,  and the  related  consolidated
statements of operations,  shareholders'  equity, and cash flows for each of the
three years in the period ended  December 31, 1998. Our audits also included the
financial  statement schedule listed in the Index at Item 14(a). These financial
statements  and  financial  statement  schedule  are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements and financial statement schedule based on our audits.

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

     In our opinion,  the financial statements referred to above present fairly,
in  all  material  respects,   the  consolidated   financial  position  of  TCSI
Corporation at December 31, 1998 and 1997, and the  consolidated  results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1998 in conformity with generally accepted  accounting  principles.
Also,  in our opinion,  the financial  statement  schedule,  when  considered in
relation  to the  basic  consolidated  financial  statements  taken  as a whole,
presents fairly, in all material respects, the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                December 31, 1998


NOTE 1 - THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

     TCSI  Corporation  currently  operates in one  industry  segment,  which is
providing   integrated   software   products   and   services   for  the  global
telecommunications industry.

Basis of Consolidation

     The consolidated  financial  statements include the accounts of the Company
and its  wholly-owned  subsidiary.  All  significant  intercompany  accounts and
transactions have been eliminated.

Revenue Recognition

     The Company  generates  revenue through two sources:  software licenses and
services.  The  Company's  license  revenues are  generated  from  licensing the
Company's products directly to end users and original  equipment  manufacturers.
Service  revenues are  generated  from  maintenance  contracts  and training and
consulting services performed for customers that license the Company's products.

     The Company  provides  its  software to  customers  under  contracts  which
generally include both software  licensing fees and systems solutions  services.
The    Company     accounts    for     fixed-price     contracts    using    the
percentage-of-completion  method.  Percentage of completion is determined  using
the number of dollars  incurred as compared  to the total  estimated  dollars to
complete the contract. Actual remaining effort under fixed-price contracts could
vary significantly from the estimates, and such differences could be material to
the  financial  statements.  Differences  between  invoiced  amounts and revenue
recognized  are  reflected  as unbilled  receivables  or deferred  revenue.  The
Company  recognizes  revenue from software  licensing fees when a  noncancelable
license  agreement has been signed,  the product has been shipped,  the fees are
fixed and determinable, collectibility is probable and vendor-specific objective
evidence  of fair value  exists to  allocate  the total fee to  elements  of the
arrangement.

     Statement of Position 97-2,  Software Revenue Recognition ("SOP 97-2"), was
issued in October 1997 by the American Institute of Certified Public Accountants
("AICPA")  and was amended by Statement of Position  ("SOP  98-4").  The Company
adopted SOP 97-2 effective  January 1, 1998. Based on its  interpretation of SOP
97-2 and SOP 98-4, the Company believes its current revenue recognition policies
and practices are consistent with these pronouncements.  Additionally, the AICPA
issued SOP 98-9 in December 1998, which provides certain amendments to SOP 97-2,
and is effective for transactions  entered into by the Company beginning January
1, 2000.  Implementation  guidelines for SOP 98-9 and SOP 98-4 have not yet been
issued.   Once  available,   such   implementation   guidelines  could  lead  to
unanticipated  changes in our current  revenue  recognition  policies  and these
changes could affect the timing of the Company's  future revenues and results of
operations.

Stock-Based Compensation

     The Company  grants stock options for a fixed number of shares to employees
with an  exercise  price  equal to the fair  value of the  shares at the date of
grant.  The  Company  accounts  for  stock  option  grants  in  accordance  with
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees," and,  accordingly,  recognizes no compensation expense for the stock
option grants.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)


Software Development Costs

     Statement of Financial  Accounting  Standards No. 86,  "Accounting  for the
Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed",  provides
for the  capitalization  of certain  software  development  costs incurred after
technological  feasibility  of the  software is achieved.  Software  development
costs subject to potential  capitalization  were not material in 1998,  1997 and
1996, and, as such, were expensed.

Income Taxes

     Deferred  income taxes are recorded for temporary  differences  between the
bases of assets and  liabilities  as recognized  by tax laws and their  carrying
value as reported in the consolidated financial statements.

Comprehensive Income (Loss)

     The Company adopted  Statement of Financial  Accounting  Standards No. 130,
"Reporting  Comprehensive  Income" ("SFAS 130") as of January 1, 1998.  SFAS 130
establishes  standards  for the reporting  and display of  comprehensive  income
(loss) and its components.  SFAS 130 requires  unrealized gains or losses on the
Company's  available-for-sale  securities and changes in the accumulated foreign
currency translation  adjustments which, prior to the adoption of SFAS 130, were
reported  separately in shareholders'  equity,  to be disclosed as components of
comprehensive   income  (loss).   Prior  year  financial  statements  have  been
reclassified  as  necessary  to conform  to the  requirements  of SFAS 130.  The
adoption of SFAS 130 had no impact on the  Company's  net income (loss) or total
shareholders' equity.

     Components of  comprehensive  loss for the years ended  December 31 were as
follows:

                                                        1998          1997

Per Share Information

     Basic  earnings  (loss) per share is computed  using the  weighted  average
number  of common  shares  outstanding.  Diluted  earnings  (loss)  per share is
computed using the weighted  average number of shares  outstanding  and dilutive
common stock equivalents from the Company's stock option plans, calculated using
the treasury  stock method.  The following  table sets forth the  computation of
basic and diluted earnings (loss) per share:

     *Since the Company had net losses in 1998 and 1997, weighted-average common
     shares  (with an exercise  price less than the average  market price of the
     Company's  common  stock)  which  were  not  included  in the 1998 and 1997
     computations because their effects would be antidilutive were as follows:

Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the amounts  reported in the financial  statements  and
accompanying notes. Actual results could differ from those estimates.

Reclassifications

     Certain prior year balances  have been  reclassified  to conform to current
year presentation.

Recent Accounting Pronouncements

     In March 1998,  the  American  Institute of  Certified  Public  Accountants
finalized  Statement  of Position  ("SOP")  98-1,  "Accounting  for the Costs of
Computer  Software  Developed or Obtained for Internal  Use",  which defines the
types of  costs  that are  capitalizable  for  computer  software  projects  and
requires  all other  costs to be expensed  in the period  incurred.  The new SOP
requires  that in order for costs to be  capitalizable  they must be intended to
create a new system or add  identifiable  functionality  to an existing  system.
This SOP is effective for fiscal years  beginning  after December 15, 1998, with
earlier  application  permitted.  The Company does not believe that its adoption
will have a material impact on its financial position, results of operations, or
cash flows.

NOTE 2 - MARKETABLE SECURITIES

     The Company  accounts for its  marketable  securities  under the  Financial
Accounting   Standards  Board   Statement  No.  115,   "Accounting  for  Certain
Investments  in  Debt  and  Equity   Securities."   Management   determines  the
appropriate  classification  of investments  and debt  securities at the time of
purchase  and  reevaluates  such  designation  as of each  balance  sheet  date.
Investments are classified as  held-to-maturity  when the Company has the intent
and ability to hold the securities to maturity.  Held-to-maturity securities are
stated at amortized  cost.  Investments not classified as such are classified as
available-for-sale.  Available-for-sale  securities  are  stated at fair  value,
determined by quoted market prices, with the unrealized gains and losses, net of
tax,  included in  accumulated  other  comprehensive  loss within  shareholders'
equity.  Realized and  unrealized  gains and losses from  investments  have been
insignificant  to the  results  of  operations  and  financial  position  of the
Company.

     Marketable securities at December 31 consist of the following:

outstanding  is less than one year and the range of exercise  prices is $3.83 to
$3.90 per share.  The weighted  average grant date fair value of options granted
during 1996 was $13.86 per share.  As discussed  above,  all  ungranted  options
expired  March 1, 1996 so no options  have been  available  for grant since that
date.

1991 Stock Incentive Plan

     The 1991 Stock  Incentive Plan ("Stock Plan")  provides for the issuance of
up to 3.0 million common shares for the granting of options or restricted shares
to employees,  directors, and consultants.  The Stock Plan provides for issuance
of  incentive  options at an  exercise  price per share of not less than 100% of
fair value at the time of the grant.  The Stock Plan also  provides for issuance
of  nonstatutory  options and  restricted  stock awards at an exercise price per
share  equal  to the fair  value of the  shares  at the date of  grant.  Options
granted under the Stock Plan  generally  have a term of up to six years from the
date of the grant and are exercisable to the extent vested.  The option term and
vesting  schedule is established by the 1991 Stock Plan Committee at the date of
grant. No grants of restricted stock have been issued under the Stock Plan.

     In 1996, the Company's shareholders approved an amendment to the Stock Plan
that  increased  the number of common  shares  reserved for option grants to 7.5
million. Beginning January 1, 1997, the number of options eligible to be granted
under the Stock Plan automatically increases by 0.75 million each year.

     Information regarding the Stock Plan is as follows:

1994 Outside Directors Stock Option Plan

     In 1995,  the  Company's  shareholders  adopted the 1994 Outside  Directors
Stock Option Plan  ("Directors'  Plan") which provides for the issuance of up to
300,000  common shares for options to  nonemployee  directors.  In May 1998, the
board approved an amendment to the plan whereby each eligible  director is to be
granted  options to purchase  20,000 shares upon  appointment or election to the
Board of  Directors  ("Board");  before  the  amendment,  the  amount was 31,500
shares.  In addition,  the  amendment  provides that current  directors  will be
granted  options to purchase an  additional  5,000  shares per year;  before the
amendment,  the amount was 6,000  shares per year.  Options  vest monthly over a
three-year  period. At December 31, 1998, the weighted average  contractual life
of options outstanding is 3.3 years and the range of exercise prices is $2.39 to
$10.75 per share.

     At December 31, 1998, there were 132,500 options  available for grant under
the Directors' Plan.

     The weighted  average grant date fair value of options granted during 1998,
1997, and 1996 was $5.05, $3.78, and $5.40, per share, respectively.

Stock-Based Compensation and Pro forma Consolidated Information

     Statement  of  Financial  Accounting  Standards  No. 123,  "Accounting  for
Stock-Based  Compensation" ("SFAS 123"),  requires disclosure of the fair value,
as defined,  of options granted to employees and related  compensation  expense.
The fair value for these  options  was  estimated  at the date of grant  using a
Black-Scholes  option-pricing  model.  A  weighted-average  expected life of the
option of four years and no dividend yield were assumed.

     The  Black-Scholes   option  valuation  model  was  developed  for  use  in
estimating the fair value of traded  options which have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because the Company's  employee stock options have  characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  in
management's  opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     The Company is also required to present pro forma consolidated  information
as if provisions  of SFAS 123 had been  implemented  as of January 1, 1995.  For
purposes of pro forma  disclosures,  the estimated  fair value of the options is
amortized to expense over the options' vesting period. The effect of adjustments
made to obtain pro forma  consolidated  net loss per share is not expected to be
indicative of the effect on future periods' pro forma consolidated  results. The
Company's pro forma consolidated  information for the years ended December 31 is
as follows:

Employee Stock Purchase Plan

     In December  1996,  the Company  adopted the Employee  Stock  Purchase Plan
("Purchase  Plan") under  Section 423 of the Internal  Revenue Code and reserved
500,000  shares of Company common stock for issuance under this plan. The number
of shares available under the Purchase Plan will increase annually by the lesser
of  100,000  shares,  1% of  the  Company's  outstanding  shares,  or an  amount
determined by the Board.  All  employees,  as defined by the Purchase  Plan, may
contribute up to 15% of their  compensation  to purchase shares of the Company's
common stock at the lesser of 85% of the fair market  value at the  beginning or
end of each  six-month  offering  period.  The offering  periods  commence  each
February and August.  During the years ended December 31, 1998 and 1997, 145,153
and 87,504 shares, respectively,  of common stock were issued under the Purchase
Plan.  Under the Purchase  Plan,  267,343  shares are  available for issuance at
December 31, 1998.

Option Repricing

     In January 1997, the Company's  Board approved the repricing of 1.1 million
options  granted under the 1991 Stock  Incentive  Plan. All employees were given
the  opportunity  to exchange  their  current  options  for new options  with an
exercise price of $6.63 per share (fair value of the related common shares as of
January 28, 1997). Of these options,  50% vested in January 1998, 25% in January
1999,  and 25% will vest in January  2000.  These  options  are  included in the
respective option schedules as cancellations and subsequent grants.

NOTE 7 - INCOME TAXES

     Realization  of the Company's net deferred tax assets is dependent upon the
Company  generating  sufficient  taxable  income in future years in  appropriate
jurisdictions  to obtain benefit from the reversal of temporary  differences and
from net operating loss and tax credit carryforwards. The amount of deferred tax
assets  considered  realizable  is subject to  adjustment  in future  periods if
estimates of future taxable income are reduced,  which would  negatively  impact
the Company's income tax provision in future periods.

     The current and deferred portions of the income tax provision (benefit) for
the years ended December 31 are as follows:

     The provision  (benefit) for income taxes differed from the amount computed
by applying the Federal  statutory  income tax rate for the years ended December
31 as follows:

                                             1998          1997          1996

     *Not Meaningful

     TCSI  recorded an income tax provision  (benefit) of $1.1  million,  $(1.4)
million,  and $152,000 for 1998, 1997, and 1996 respectively.  The tax provision
for 1998 differed from the Federal  statutory  rate primarily due to a valuation
allowance  recorded in the  current  year of  approximately  $2.4  million.  The
valuation  allowance  was  provided to reduce the net deferred tax assets to the
amount which management believes,  based on the weight of available evidence, is
recognizable on a more likely than not basis.

     At December 31, 1998, the Company had a net operating loss carryforward for
Federal income tax purposes of  approximately  $8.1 million which will expire in
varying  amounts  in 2012 and 2018 and a  foreign  tax  credit  carryforward  of
approximately $850,000 which will expire in the year 2001.

NOTE 8-FOREIGN CURRENCY TRANSLATION

     The Company has  determined  that the  functional  currency of each foreign
operation is the local currency. The effects of translation rate changes related
to long term  assets and  liabilities  located  outside  the  United  States are
included  as  a  component  of  accumulated  other   comprehensive  loss  within
shareholders'  equity.  Through 1998,  foreign  currency  transaction  gains and
losses (which are recorded in the  consolidated  statements of operations)  have
not been significant.

NOTE 9-ACQUISITION OF GTE-NMO

     In December 1998, the Company  completed the  acquisition of the net assets
of GTE Network  Management  Organization  ("GTE-NMO"),  a former division of GTE
Government Systems  Corporation  ("GTE").  GTE-NMO is a

Bothell,  Washington-based  organization  that develops and  implements  network
management solutions. It licenses WorldWin communications software ("WorldWin").
WorldWin is a family of operations  support  system  ("OSS")  products  offering
telephony,  cable, and wireless  providers a flexible platform for launching new
services,   while  protecting   existing  network  The  acquisition   price  was
approximately $7,958,000 and consisted of cash of $6,513,000,  forgiveness of an
existing receivable of $355,000,  the assumption of a liability of $333,000, and
acquisition costs of $757,000.  The acquisition was accounted for as a purchase.
The purchase price for book purposes was allocated by the Company  approximately
as follows (in thousands):

     Intangible  assets  acquired in connection  with the  acquisition are being
amortized over the estimated lives noted above.

     The  operating  results of this  acquisition  are included in the Company's
consolidated  results of operations from the date of acquisition.  The unaudited
pro forma  consolidated  information  set forth below presents the  consolidated
results of operations  (as if the  acquisition  had occurred at the beginning of
the periods presented) for the period from the date of acquisition, after giving

     Purchased  In-Process  Technology.  Management estimates that approximately
$831,000 of the purchase price represents purchased  in-process  technology that
has not yet reached technological feasibility and has no alternative future use.
Accordingly,  this amount was expensed in 1998. The value assigned to in-process
technology  was determined by identifying  the product  development  projects in
areas for which  technological  feasibility  had not been achieved and assessing
the  date  of  completion  of the  product  development  effort.  The  state  of
completion  was  determined  by  estimating  the costs and time incurred to date
relative  to those  costs  and time to be  incurred  to  develop  the  purchased
in-process   technology  into  commercially  viable  products,   estimating  the
resulting net cash flows only from the percentage of product development efforts
complete at the date of acquisition,  and discounting the net cash flows back to
their present value.  The discount rate included a factor that took into account
the  uncertainty   surrounding  the  successful  development  of  the  purchased
in-process technology. Research and development costs to bring the products from
the acquired  company to  technological  feasibility  are not expected to have a
material impact on the Company's future results of operations or cash flows.

     Developed Technology.  Management estimates that approximately  $772,000 of
the  purchase  price  represents  developed  technology.  The value  assigned to
developed  technology was determined using an income approach  methodology which
estimated  development  and technical  support  expenses and deducting them from
projected revenues to arrive at projected earnings before interest and taxes.

     Core Technology.  Management  estimates that  approximately $1.8 million of
the purchase price represents  purchased core technology.  The value assigned to
core technology was determined using an income approach  methodology.  GTE-NMO's
core technology is comprised of its existing products.

     Assembled  Workforce.  Management estimates that approximately $0.7 million
of the purchase price represents the value of the assembled workforce. The value
of the assembled  workforce was estimated  using a cost approach.  This approach
identified the employees that would require significant cost to replace them and
train new  employees.  Next,  each  employee's  fully  burdened cost  (including
salary,  benefits  and  overhead),  the  cost  to  train  the  employee  and the
recruiting costs (such as locating, interviewing and hiring) were estimated. The
costs were totaled to estimate the value of the assembled workforce.

     A company's  assembled  workforce  represents  an asset which  incorporates
several factors such as the knowledge and expertise specific to the company, its
products  and its ability to generate  sales and future  profitability,  and the
logistics of having a workforce in place without the need to recruit, interview,
hire and train new employees.  These  characteristics are very important in many
industries,  especially  in high  technology  companies,  where there is often a
shortage of skilled  employees and where the competition to hire them is strong.
The more specialized the workforce, the greater the cost of its assemblage,  and
hence, the greater its value.

NOTE 10-COMMITMENTS

     The  Company  is  obligated  under  operating  lease   agreements  for  its
facilities  with  noncancelable  lease  terms in excess of one year.  Certain of
these leases contain renewal options and require that the Company pay for taxes,
insurance,  and maintenance expenses. Rent expense under these leases during the
years 1998,  1997,  and 1996 was $2.2 million,  $2.2 million,  and $2.3 million,
respectively. Future minimum lease payments on noncancelable operating leases as
of December 31, 1998 are as follows (in thousands):

NOTE 11-LEGAL PROCEEDINGS

     In November  1996,  a purported  class  action  complaint  was filed in the
Superior  Court  of the  State of  California,  Alameda  County,  by  Albert  J.
Copperstone and Joseph  Siciliano  against the Company,  certain of its officers
and directors,  and certain  underwriters (the "Copperstone State Action").  The
complaint in the Copperstone  State Action alleges that during a purported class
period of October 11, 1995 to September  25, 1996,  defendants  made  materially
false and misleading  statements concerning the Company's business condition and
prospects,  in violation of California  law. The  plaintiffs in the  Copperstone
State Action seek damages of an  unspecified  amount.  In July 1997,  plaintiffs
voluntarily  dismissed the underwriter  defendants  without  prejudice.  In June
1998,  plaintiffs  filed  their  second  amended  complaint.  In  January  1999,
defendants'  demurrers to that  complaint  were orally  overruled.  In response,
certain of the defendants filed answers to the second amended  complaint,  while
the remaining  defendants are awaiting the written order overruling  defendants'
demurrers.

     In November 1996, a purported  derivative action complaint was filed in the
Superior  Court of the State of  California,  Alameda  County,  by Mike  Tinkler
against the Company's Board of Directors and the Company as a nominal  defendant
(the  "Tinkler  Derivative  Action").  The  complaint in the Tinkler  Derivative
Action  also names the  Company as a nominal  defendant.  The  plaintiff  in the
Tinkler  Derivative  Action seeks damages of an unspecified  amount. In February
1998,  plaintiff filed a second amended  complaint  alleging breach of fiduciary
duties and violation of the  California  Corporations  Code.  In December  1998,
defendants answered the second amended complaint.

     In September  1997, a purported  class  action  complaint  was filed in the
United  States  District  Court  for the  Northern  District  of  California  by
Copperstone  and  Siciliano  against the Company and certain of its officers and
directors (the  "Copperstone  Federal Action").  The Copperstone  Federal Action
contains  virtually  identical  factual  allegations  as the  Copperstone  State
Action,  and alleges  violations of Sections  10(b) and 20(a) of the  Securities
Exchange  Act of 1934 and SEC Rule  10b-5.  The  plaintiffs  in the  Copperstone
Federal  Action also seek damages of an  unspecified  amount.  In January  1998,
defendants moved to dismiss the Copperstone  Federal Action.  In April 1998, the
Court  ordered  plaintiffs  to  certify a class  prior to ruling on  defendants'
motion to dismiss.  Plaintiffs  thereafter  provided  shareholders with a period
during  which they could choose to be excluded  from the class;  this period has
subsequently  expired.  In January 1999, the court  dismissed the complaint with
leave to amend.  In February 1999, the plaintiffs  moved to stay the Copperstone
Federal Action in favor of the Copperstone  State Action, or for additional time
in which to file an amended complaint.  Defendants have requested that the Court
dismiss the  Copperstone  Federal  Action with  prejudice.  Oral argument on the
plaintiff's motion is scheduled for April 1999.

     No trial in any of these actions is scheduled.  The Company believes it has
meritorious defenses to all of these actions, and intends to defend each of them
vigorously.  The  Company is also a party as a  defendant  in various  lawsuits,
contractual  disputes,  and other  legal  claims,  the  results of which are not
presently determinable. In the opinion of management,  resolution of these legal
actions is not  expected  to have a  material  adverse  effect on the  financial
position  of the  Company.  However,  depending  on the  amount and  timing,  an
unfavorable  resolution  of any of these  matters  could  materially  affect the
Company's  financial  position,  results of operations,  or cash flows in future
periods.

     In 1997, Atmel Corporation ("Atmel") made a claim under the 1996 TCSI/Atmel
Corporation  Purchase  Agreement.  In 1998,  management  obtained  an  equitable
settlement  of this matter with the escrow agent  releasing  $550,000 (of a $1.0
million escrow fund) plus interest to TCSI, and the remaining $450,000 less fees
to Atmel. The settlement is reported as a nonrecurring  special gain in the 1998
consolidated statement of operations.

NOTE 12-NONRECURRING SPECIAL ITEMS

     In 1998, the Company recorded a nonrecurring gain of $550,000 following the
settlement of litigation  (described in Note 11 above)  related to the sale of a
non-telecom  business unit. In 1997, the Company concluded the sale of equipment
resulting in a nonrecurring loss of $1.1 million.  In 1996, the Company recorded
a  nonrecurring  gain of $7.9 million  related to the  licensing of its embedded
wireless technology to Atmel Corporation  ("Atmel").  These gains and losses are
described in further detail below.

     The Company  incurred a charge to  operations  of $1.1 million in the first
two quarters of 1997 resulting from adjustments to the market-value of equipment
held for resale related to the termination of a  transportation  contract in the
third  quarter of 1996.  The Company  concluded the sale of the equipment in the
third quarter of 1997.  Related to this same agreement,  in the third quarter of
1996, the Company recorded a charge of  approximately  $3.3 million to cover the
costs  related to the  termination  of this  agreement.  The  customer  paid the
Company approximately $5.3 million to terminate the agreement.

     As part of the Company's strategy to focus on its core telecom  operations,
in November  1996,  the Company  licensed its embedded  wireless  technology and
related  product  lines to Atmel  Corporation  ("Atmel")  in exchange  for Atmel
common stock valued at $10.0 million. In the fourth quarter of 1996, the Company
recorded a gain on this licensing of its

stock  (described  as "Gain on sale of  investment  in common stock" in the 1996

     In February 1999, the Company's  Board declared a dividend  distribution of
one preferred share purchase right for each share of the Company's  common stock
outstanding.  Each right will entitle  shareholders to buy 1/1000th of one share
of the Company's Series A Participating  Preferred Stock at an exercise price of
$13.00.  The rights  will  become  exercisable  following  the tenth day after a
person or group  announces  acquisition  of 15% or more of the Company's  common
stock or announces  commencement  of a tender offer,  the  consummation of which
would  result in  ownership  by the person or group of 15% or more of the common
stock.  The Company  will be entitled to redeem the rights at $0.01 per right at
any time on or before the tenth day following  acquisition  by a person or group
of 15% or more of the Company's common stock.

     The  dividend   distribution   was  made  on  March  11,  1999  payable  to
