ITEM 1. BUSINESS.

Tollgrade Communications, Inc. is a leading provider of hardware and
software network assurance testing solutions for the telecommunications and
cable broadband industries. We design, engineer, market and support test
systems, test access and status monitoring products which enable telephone and
cable operators to efficiently manage their networks in an age of increased
competition, continually evolving technology and ongoing pressure to control or
reduce costs. We provide equipment that enables telephone companies to repair
their wire telephone lines when they are not functioning properly. When the
telephone lines are out of service, our products help to diagnose the problem.
In addition, our products can assess whether the lines are suitable for Digital
Subscriber Line (DSL) service. Cable networks are highly dependent on power
supplies; if such power supplies fail, the network goes down. We provide
products to cable companies that monitor the status of those power supplies.

We were incorporated in Pennsylvania in 1986, began operations in 1988
and completed our initial public offering in 1995. Our principal offices are
located at 493 Nixon Road, Cheswick, Pennsylvania 15024 and our telephone number
is (412) 820-1400.

We make available free of charge on our Internet website
(www.tollgrade.com) our annual reports on Form 10-K, quarterly reports on Form
10-Q, current reports on Form 8-K, and all amendments to those reports filed or
furnished pursuant to Section 13(a) of the Securities Exchange Act of 1934, as
amended, as soon as reasonably practicable after we electronically file such
material with, or otherwise furnish it to, the SEC.

PRODUCTS

TELECOMMUNICATION TEST SYSTEMS

Our proprietary telecommunications test access products enable
telephone companies to use their existing line test systems to remotely diagnose
problems in "Plain Old Telephone Service" (POTS) lines containing both copper
and fiber optics. POTS lines comprise the vast majority of lines in service
today throughout the world. In addition to traditional voice service, POTS lines
provide connections for popular devices such as computer modems and fax
machines. POTS excludes non-switched and private lines, such as data
communications service lines, commonly referred to as "special services."

An important aspect of maintaining a POTS network is the ability to
remotely test, diagnose and locate any problems within the network. In general,
POTS line test systems, which are located at telephone companies' central
offices, focus on helping local exchange carriers conduct the full range of
fault diagnosis in the "local loop," the portion of the telephone network that
connects end users to the central office. In addition, line test systems have
the ability to remotely qualify, deploy and maintain next generation services
including DSL and Integrated Services Digital Network (ISDN) services. These
test systems reduce the time needed to identify and resolve problems,
eliminating or reducing the costs of dispatching a technician to the problem
site. Most POTS line test systems, however, were designed only for use over
copper wireline; as a result, traditional test systems cannot access local loops
in which fiber-optic technology has been introduced.

Our proprietary Metallic Channel Unit (MCU(R)) products solve this
problem by mimicking a digital bypass pair, which is essentially a telephone
circuit that connects central test measurement devices to the copper circuits
close to the customer, known as "the last mile." Our DigiTest(R) system
represents the future of telecommunication network testing, combining our line
test system with a next generation test platform to provide complete hardware
testing for POTS and local loop prequalification and in-service testing for DSL
service.

MCU

Our core MCU products plug into Digital Loop Carrier (DLC) systems, the
large network transmission systems used by telephone companies to link the
copper and fiber-optic portions of the local loop. MCU products allow our
customers to extend their line testing capabilities to all of their POTS lines,
including copper and fiber-optic lines linked by DLCs. DLC systems, which are
located at telephone companies' central offices and at remote sites within local
user areas, effectively multiplex the services of a single fiber-optic line into
multiple copper lines. In many instances, several DLC systems are located at a
single remote site to create multiple local loops that serve several thousand
different end-user homes and businesses. Generally, for every DLC remote site,
customers will deploy at least two MCU line-testing products.

To ensure the compatibility of our MCU products with the major DLC
systems produced by various telecommunication equipment manufacturers, we have
entered into license agreements, and in most cases pay royalties for the use of,
the proprietary design integrated circuits (PDICs) unique to each DLC system. We
maintain royalty-based PDIC license agreements with Lucent Technologies, Inc.,
Fujitsu Network Transmission Systems, Inc., Zhone Technologies, Inc., Advanced
Fibre Access Communications (a wholly owned subsidiary of Advanced Fibre
Communications, Inc., or AFC) and Adtran, Inc., the terms of all but one of
which automatically renew (unless earlier terminated) for periods of between one
and five years; the other agreement has a perpetual term. We paid $1,827,000,
$847,000 and $835,000 in 2001, 2002 and 2003, respectively, in royalties under
these license agreements, which are calculated either as a percentage of the
list price of MCU products sold or as a fixed amount per MCU unit that
incorporates the licensed technology. We also maintain PDIC license agreements
that do not contain royalty provisions with AFC, Alcatel USA Sourcing, L.P.
(formerly DSC Technologies Corporation), UTSTARCOM, Inc., Next Level
Communications and SAGEM SA; the expiration dates of these agreements range from
November 2004 to May 2007, with renewal provisions for periods of one or more
years, unless earlier terminated.

We also employ our MCU technology in connection with home and business
alarm systems. As with POTS line testing, home alarm systems must be monitored
from the alarm company's headquarters along a hybrid copper and fiber-optic
line. Our alarm-related MCU products, which are installed at both central office
and remote locations, facilitate the transport of analog alarm signals from
subscribers' homes to alarm company monitoring stations across the hybrid
telephone network.

Sales of MCU products and related hardware accounted for approximately
68%, 48% and 39% of our revenue in the years ended December 31, 2001, 2002 and
2003, respectively. See Management's Discussion and Analysis for a discussion of
this trend.

DigiTest(R) and LoopCare(TM)

Our DigiTest system electrically measures the characteristics of a
copper telephone circuit and reports those measurements to our LoopCare
Operation Support System (OSS). The LoopCare OSS, in turn, analyzes that
measurement data and creates an easy-to-understand fault condition. At the same
time, the LoopCare system can generate a dispatch to a work center so that a
repairman can fix the problem. LoopCare and DigiTest also have the capability to
tell the telephone company whether the customer line is suitable for DSL
service. In addition, upgrades to DigiTest hardware can provide troubleshooting
for DSL service problems.

LoopCare, which we acquired from Lucent in 2001, has remained the major
OSS utilized by the Regional Bell Operating Companies (RBOCs) for over
twenty-five years to test the integrity and quality of their POTS network
infrastructure. The LoopCare OSS, which we offer both as part of the DigiTest
system and as a stand-alone software product, currently manages more than 75% of
the copper pairs in the United States, and is the qualification, installation
and maintenance process for more than 150 million POTS, ISDN and DSL subscribers
worldwide.

In 2003, we announced several enhancements and additions to the
DigiTest system, including the availability of direct Ethernet connectivity to
Digital Measurement Node (DMN) test heads and the introduction of our next
generation broadband test platform, DigiTest EDGE(TM). Through Ethernet
connections, the LoopCare OSS can communicate directly with remotely deployed
DigiTest hardware, allowing it to manage up to four DMNs and eight simultaneous
test sessions through a single Internet Protocol (IP) address. DigiTest EDGE
provides a global platform for broadband test applications, by combining a
narrowband and wideband metallic testing platform with DSL, Asynchronous
Transfer Mode (ATM), IP and Hypertext Transfer Protocol (HTTP) performance
tests. This combination of test capabilities, when managed by our LoopCare OSS,
enables service providers to accurately isolate a DSL problem between the
customer's premises, the local exchange carrier's local loop and Digital
Subscriber Line Access Multiplexer (DSLAM) serving network, and the Internet
service provider's data network.

We market and sell our DigiTest products directly to customers as well
as through certain continuing original equipment manufacturer (OEM) arrangements
with Lucent and Nortel Networks. The Lucent agreement, which expired under its
original terms in September 2003 but has been extended through March 31, 2004
and is currently under renegotiation, allows Lucent to resell LoopCare software
on an OEM basis.

We have licensing arrangements with Nortel, Acterna, LLC and Aware,
Inc. for certain technology related to our DigiTest products and pay royalties
and license fees for the use of such technology on a fixed per unit basis. The
license agreement with Acterna expires by its terms in 2008, unless earlier
terminated, and the agreements with Aware and Nortel contain automatic renewal
terms, unless earlier terminated. We also have an OEM agreement in place with
Electrodata, Inc. to supply a communications card for our DigiTest Edge product,
which agreement also contains automatic renewal terms, unless earlier
terminated.

Sales of the DigiTest product line (including sales with LoopCare
software) accounted for approximately 18%, 14% and 10% of the Company's revenue
for the years ended December 31, 2001, 2002 and 2003, respectively.

In addition to the LoopCare OSS software sold as part of the DigiTest
system, we also sell new LoopCare features to existing customers and the base
LoopCare OSS as a stand-alone product to Competitive Local Exchange Carriers
(CLECs) for use with test heads other than our DigiTest hardware. LoopCare
feature products include the Common Object Request Broker Architecture
(CORBA)-based Application Programming Interface, Benchmark Data Base, DSL
Testing, the Advanced Testhead Feature Package, Batch Testing, Fax Unalert, Loop
Length Reporting, Enabling Flow Through by Re-Classification of VER 55-58 Codes,
and LoopCare TCP/IP Communications Network. In addition, in December 2003, we
released a new LoopCare feature called Testing Voice Services in a Broadband
Passive Optical Network (bPON), which provides support for customer deployment
of Fiber-to-the-Premises (FTTP) solutions.

Sales of stand-alone LoopCare software and enhancements accounted for
approximately 13% and 5% of the Company's revenue for the years ended December
31, 2002 and 2003, respectively.

CABLE TESTING PRODUCTS

The Company's Cheetah(TM) performance and status monitoring products
provide a broad network assurance solution for the Broadband Hybrid Fiber Coax
(HFC) distribution system found in the cable television industry. Our Cheetah
products gather status information and report on critical components within the
cable network.

On February 13, 2003, we acquired the Cheetah product line from
Acterna, LLC, for $14,300,000 in cash plus the assumption of certain related
liabilities. The transaction provided for an earnout to be paid in the first
half of 2004 of up to $2,400,000 based on certain 2003 performance targets. The
current calculation indicates that amounts due under this provision are
immaterial. As a result of this acquisition, our cable offerings now consist of
our CheetahLight(TM) (formerly LIGHTHOUSE(R)) and CheetahNet(TM) (formerly
NetMentor(TM)) software systems and maintenance, head-end controllers, return
path switch hardware, transponders and other equipment which gather status and
performance reports from power supplies, line amplifiers and fiber optic nodes.

We have entered into license agreements with C-COR.net Corp. (formerly
C-COR Electronics, Inc.) and Alpha Technologies, Inc., through which we provide
status monitoring transponder technology incorporated into those companies'
cable network management systems. In 2003, we also entered into a separate
agreement with Alpha, the leading supplier of power management products to the
cable industry, to serve as Alpha's exclusive provider of IP-based Data Over
Cable Service Interface Specifications (DOCSIS) status monitoring equipment for
its power supply systems; this agreement contains an initial term which expires
in November 2007 and automatically renews on an annual basis thereafter unless
terminated. Presently, such equipment is still under development, but is
expected to be completed during the first quarter of 2004.

We have also entered into an OEM agreement with Brix Networks, Inc.
under which Brix will supply us with hardware and software that will allow our
customers to automate the installation and maintenance process for a variety of
IP-based services delivered over the cable broadband infrastructure, such as
high-speed Internet, Voice over Internet Protocol (VoIP) and Video on Demand.
This agreement contains an initial term which expires in September 2008 and
automatically renews on an annual basis thereafter, unless earlier terminated.
Further, the Company has entered into other license agreements for use of
certain VoIP software testing products.

Sales of the Cheetah product line (excluding Services) accounted for
approximately 4%, 5% and 27% of the Company's revenue for the years ended
December 31, 2001, 2002 and 2003, respectively.

SERVICES

Our Services offerings include software maintenance as well as our
professional services, which are designed to make sure that all of the
components of our customers' voice test systems operate properly. The Services
business was considerably expanded upon the acquisition of software maintenance
relationships related to the LoopCare and CheetahNet software product lines.

Including software maintenance, Services revenue accounted for
approximately 6%, 18% and 19% of the Company's revenue for the years ended
December 31, 2001, 2002 and 2003, respectively.

REPORTING SEGMENT

We have determined that our business has one reporting segment, the
test assurance industry. All product sales are considered components of the
business of testing infrastructure and networks for the telecommunications and
cable television industries. Although we do internally develop sales results
associated with the various product categories, this information is not
considered to be sufficient for segment reporting purposes and our chief
operating decision maker does not base critical decisions or allocate assets
based solely on this information. Our products and services have similar
economic characteristics and the same or similar production processes, and are
sold through comparable distribution channels and means to similar types and
classes of customers already in, or entering into, the telecommunications and
cable businesses.

SALES AND COMPETITION

DOMESTIC SALES

The primary customers for our products and services are the four
Regional Bell Operating Companies (RBOCs), Verizon Communications, Inc.,
BellSouth Corporation, SBC Communications Inc. and Qwest Communications
International, Inc., as well as major independent telephone companies and most
of the major cable operators. Sales in 2003 to SBC, Verizon and BellSouth
accounted for approximately 17%, 17%, and 14%, respectively, or 48%
collectively, of our total revenue for the year. Due in part to the
diversification of our product lines resulting primarily from our Cheetah
acquisition, the percentage of our revenue generated from these three RBOC
customers has declined substantially in the past year from the 70% of our 2002
revenue attributable to such customers. Because of our continued dependency on
the four RBOCs, however, the potential loss of one or more of them as customers,
or the reduction of orders for our products by one or more of them, could
materially and adversely affect our results.

INTERNATIONAL SALES

International sales represented approximately 6% of the Company's total
revenue for the year ended December 31, 2003, a percentage nearly identical to
the portion of our revenue attributable to foreign sales for 2002. Our success
in marketing and selling our telecommunications products in international
markets has been limited, due in part to incompatibility of certain of our
telecommunications products in networks employed abroad. As a result, we have
curtailed many of our efforts in marketing those products internationally. See
the discussion in our "Management's Discussion and Analysis of Financial
Condition and Results of Operations" section of this Form 10-K for a further
examination of our strategies relating to international sales.

COMPETITIVE CONDITIONS

The market for telecommunications and cable television equipment is
highly competitive. Primary competitive factors in the Company's market include
price, product features, performance, reliability, service and support, breadth
of product line, technical documentation and prompt delivery. We believe that we
compete favorably with regard to all of these factors.

The traditional competitors for our telecommunications products include
Harris Corporation, Porta Systems Corp., and Teradyne, Inc. Each of these
companies provides centralized test and management solutions for POTS networks.
Historically, we have successfully positioned ourselves against these offerings
by leveraging patented technologies, partnerships with telecommunications
equipment providers and incumbent positions within our customers' networks.

As we extend our product offerings to address DSL, FTTP, IP, and ATM
test applications for emerging next generation networks, this list of
traditional competitors is expanding to include Spirent Communications, Acterna
Corporation, Telcordia, and Micromuse. We believe that our ability to test these
next generation networks by upgrading our existing, highly automated incumbent
infrastructure provides an advantage over these new competitors in terms of
upfront deployment costs and long term operational efficiency.

With respect to our cable products, traditional status/performance
monitoring competitors include AM Communications, Scientific Atlanta, and
Electroline. Historically, we have maintained an advantage over these
competitors through the mass deployment of proprietary technology within the
major cable operators. In recent years the cable industry has adopted open,
non-proprietary standards for status/performance monitoring systems, such as
Hybrid Management Sub-layer (HMS) and DOCSIS. As a result, we have modified our
competitive strategies to better leverage exclusive partnerships with premier
cable equipment providers and to enhance our incumbent systems for the support
of Internet protocol- based service delivery.

As with the telecommunications products, the extension of our cable
products to address Internet protocol test applications expands our list of
traditional competitors to now include Micromuse, Aprisma, Agilent, and Acterna
Corporation. We feel that our ability to seamlessly integrate technology
partners, such as Brix Networks and Telchemy, with our incumbent solutions
provides an advantage over these competitors when positioning ourselves for
Internet protocol testing opportunities within the major cable operators.

MANUFACTURING

Our manufacturing operations consist primarily of quality control,
functional testing, final assembly, burn-in and shipping. We are ISO 9001:2000
registered with the British Standards Institution, Inc. ISO 9000 is a harmonized
set of standards that define quality assurance management. Written by the
International Organization for Standardization (ISO), ISO 9000 is recognized
throughout the United States, Canada, the European Union and Japan. To be
registered, the Company develops and maintains internal documentation and
processes to support the production of quality products to ensure customer
satisfaction.

For our telephony products, we utilize two key independent
subcontractors to perform a majority of the circuit board assembly and
in-circuit testing work. We also employ other subassembly contractors for our
telephony products on a more limited basis. For our Cheetah hardware, we
primarily use a single turnkey manufacturer, Dictaphone Corporation's Electronic
Manufacturing Services Division, to procure the components and assemble and test
the products. The loss of any of these subcontractors could cause delays in our
ability to meet production obligations and have a material adverse effect on our
results of operations. In addition, shortages of raw materials delivered to, or
production capacity constraints at, the Company's subcontractors could
negatively affect our ability to meet our production obligations and result in
increased prices for affected parts. Any such reduction may result in delays in
shipments of the Company's products or increases in the price of components,
either of which could have a material adverse impact on us.

Generally, our products use industry standard components; however,
application specific integrated circuits (ASICs) are also a key component of our
products and are custom made to the Company's specifications. Although we have
generally been able to obtain ASICs on a timely basis, a delay in the delivery
of these components could have a material adverse impact on the Company.

PRODUCT AND TECHNOLOGY DEVELOPMENT

Our product development personnel, many of whom are Bell Labs trained,
are organized into teams, each of which is effectively dedicated to one or more
specific product lines or technologies. We continuously monitor developing
technologies in order to introduce new or improved products as defined standards
and markets emerge. During 2003, we committed much of our research and
development resources to the development of DigiTest EDGE, which was introduced
during the year. In addition, we continue to investigate the development of new
applications for our MCU and Cheetah technologies, as well as enhancements and
new features to our LoopCare software product line and other technologies to
service the telecommunications and cable industries. For the years ended
December 31, 2001, 2002 and 2003, research and development expenses were
approximately $12,428,000, $13,839,000 and $14,925,000, respectively.

PROPRIETARY RIGHTS

The names "Tollgrade(R)", "MCU(R)", "LIGHTHOUSE(R)", "DigiTest(R)",
"Telaccord(R)" and "MICRO-BANK(R)", and our corporate logo are registered
trademarks of the Company. "LoopCare(TM)", "Cheetah(TM)", "CheetahNet(TM)",
"CheetahLight(TM)", "Edge(TM)", "NetMentor(TM)" and "MLT((TM))" are common law

the Company. We have obtained three United States patents on the MCU products
with expiration dates ranging from 2010 to 2014, two United States and one
Canadian patent on cable technology that expire in 2017 and 2018, one Canadian
patent and seven United States patents on other telecommunications technology,
which expire in dates ranging from 2017 to 2019. In addition, we have four
United States, three Canadian, one Taiwanese and seven international patent
cooperation treaty patent applications pending. We will seek additional patents
from time to time related to our research and development activities. We protect
our trademarks, patents, inventions, trade secrets, and other proprietary rights
by contract, trademark, copyright and patent registration, and internal

BACKLOG

Our backlog consists of firm customer purchase orders and signed
software maintenance agreements. As of December 31, 2003, the Company had
backlog of approximately $15,347,000, all of which is expected to be filled in
2004, as compared to approximately $7,200,000 of backlog at December 31, 2002.

We have entered into extended LoopCare software maintenance agreements
with two of the four RBOCs, one of which has a term of three years expiring on
December 31, 2005, and the second of which expires on December 31, 2004 (we also
completed an annual maintenance agreement with a third RBOC customer on January
6, 2004 which expires on December 31, 2004). The fourth RBOC maintenance
agreement will expire December 31, 2004, with an option for a one-year
extension. Our backlog at December 31, 2003 includes approximately $6,105,000
related to software maintenance contracts. We have adopted a policy to include a
maximum of twelve months revenue from multi-year agreements in reported backlog.
Software maintenance revenue is deemed to be earned and recognized as income on
a straight-line basis over the terms of the underlying agreements. Periodic
fluctuations in customer orders and backlog result from a variety of factors,
including but not limited to the timing of significant orders and shipments.
Although these fluctuations could impact short-term results, they are not
necessarily indicative of long-term trends in sales of our products. Also
included in backlog as of December 31, 2003 is a blanket purchase order for
$3,100,000 which is intended to cover one customer's MCU requirements for all of
calendar year 2004 and a non-cancelable order for $1,790,000 related to a cable
product under development which is currently in beta testing.

GOVERNMENT REGULATION

The telecommunications industry is subject to regulation in the United
States and other countries. Federal and state regulatory agencies, including the
Federal Communications Commission (FCC) and various state public utility and
service commissions, regulate the activities of most of our domestic customers.
Although such regulation does not typically affect the Company directly, the
effects of such regulations on our customers may, in turn, adversely impact our
business and operating results. Governmental authorities have also promulgated
regulations which, among other things, set installation and equipment standards
for private telecommunications systems and require that all newly installed
hardware be registered and meet certain government standards.

EMPLOYEES

As of December 31, 2003, we had 293 full-time employees, all of whom
were located in the United States. None of our employees are represented by a
collective bargaining agreement.

RISKS FACTORS THAT MIGHT AFFECT FUTURE OPERATING RESULTS AND FINANCIAL CONDITION

We wish to caution each reader of this Form 10-K to consider the following
factors and certain other factors discussed herein and in other past reports,
including but not limited to prior year Form 10-K and Form 10-Q reports and
annual reports filed with the SEC. Our business and results of operations could
be seriously impaired by any of the following risks. The factors discussed
herein may not be exhaustive. Therefore, the factors contained herein should be
read together with other reports and documents that we file with the SEC from
time to time, which may supplement, modify, supercede or update the factors
listed in this document.

- Because we depend upon a few major customers for a majority of our
revenues, the loss of any of these customers would significantly
reduce our revenues and net income. Furthermore, decreases in the
capital budgets of these customers could

-8-



lead to their reduced demand for our products, which could in turn
have a material adverse affect on our business and results of
operation. The capital budgets of our RBOC customers, as well as many
of our other customers, are dictated by a number of factors, most of
which are beyond our control, including:

- the conditions of the telecommunications market and the
economy in general;

- subscriber line loss and related reduced demand for
telecommunications services;

- disputes between our customers and their organized labor
groups;

- the failure to meet established purchase forecasts and
growth projections; and

- competition among the RBOCs, competitive exchange carriers
and wireless telecommunications and cable providers.

If the financial strength of our major customers should deteriorate,
or if they have difficulty acquiring investment capital due to any of
these or other factors, a substantial decrease in our revenues would
likely result.

- A large portion of our sales are attributable to our core proprietary
MCU technology. MCU sales largely depend upon the rate of deployment
of new, and the retrofitting of existing, Digital Loop Carrier (DLC)
systems in the United States. Installation and replacement of DLC
systems are, in turn, driven by a number of factors, including the
availability of capital resources and the demand for new or better
POTS service. The current plans of our customers, if executed, to
implement next generation network improvements such as FTTP, which
does not require the use of our MCU products like the present hybrid
POTS network, could materially impact our MCU sales. If our major
customers fail to continue to build-out their DSL networks and other
projects requiring DLC deployments, or if we otherwise satisfy the
domestic telecommunications market's demand for MCUs, our future
results would be materially and adversely affected.

- We depend upon a relatively narrow range of products for the majority
of our revenue. Our success in marketing our products is dependent
upon their acceptance by our customers, which in some cases have their
own proprietary requirements. The adoption of industry-wide standards,
such as the HMS and DOCSIS cable standards, may result in the
elimination of or reductions in the demand for many of our proprietary
products, like our Cheetah head-end hardware products and other
Cheetah products. Furthermore, standards for new services and
technologies continue to evolve, requiring us to continuously modify
our products or to develop new versions to meet these new standards.
If we are unable to forecast the demand for, and to develop new
products or to adapt our existing products to meet, these evolving
standards and other technological innovations, or if our products and
services do not gain the acceptance of our customers, there could be a
negative effect on our future results.

- Our customers have historically been subject to a number of
governmental regulations, many of which have been repealed or amended
as a result of the passage of The Telecommunications Act of 1996.
Deregulatory efforts have affected and likely will continue to affect
our customers in several ways, including the introduction of
competitive forces into the local telephone markets and the imposition
(or removal) of controls on the pricing of services; these and other
regulatory changes may affect our customers' deployments of future
services. Moreover, as the Federal Communications Commission (FCC)
adopts new and amends existing regulations, and as the courts analyze
the FCC's authority to do so, our customers cannot accurately predict
the rules by which they will be able to compete in their respective
markets. Any changes in the telecommunications regulatory environment
that, among other results, increase our costs of doing business,
require our customers to share assets with competitors or prevent the
Company or our customers from engaging in business activities they may
wish to conduct, could significantly reduce the demand for our
products and adversely affect our future results.

- Many of our products consist entirely or partly of proprietary
technology owned by us. Although we seek to protect our technology
through a combination of copyrights, trade secret laws, contractual
obligations and patents, these protections many not be sufficient to
prevent the wrongful appropriation of our intellectual property, nor
will they prevent our competitors from independently developing
technologies that are substantially equivalent or superior to our
proprietary technology. If we are unable to successfully assert and
defend our proprietary rights in the technology utilized in our
products, or if third parties are able to successfully assert that our
use of technology infringes upon the proprietary rights of others, our
future results could be adversely affected.

- Some of our products require technology that we must license from the
manufacturers of systems with which our products must be compatible.
The success of our proprietary MCU products in particular rely upon
our ability to acquire and maintain licensing arrangements with the
various manufacturers of DLC systems for the PDICs unique to each.
Although most of our PDIC licensing agreements have perpetual renewal
terms, all of them can be terminated by either party. If we are unable
to obtain the PDICs necessary for our MCU products to be compatible
with a particular DLC system, we may be unable to satisfy the needs of
our customers. Furthermore, future PDIC license agreements may contain
terms comparable to, or materially different than, the terms of
existing agreements, as dictated by competitive or other conditions.
The loss of these PDIC license agreements, or our inability to
maintain an adequate supply of PDIC's on acceptable terms, could have
a material adverse effect on our business.

- We depend upon a limited number of third party subcontractors to
manufacture certain aspects of our products. Furthermore, the
components of our hardware products are procured from a limited number
of outside suppliers. Our success depends in part upon our ability to
obtain timely deliveries of those parts from our suppliers. Although
our products generally use industry standard products, some parts,
such as ASICs, are custom made to our specifications. If we were to
encounter a shortage of key manufacturing components from limited
sources of supply, or experience manufacturing delays caused by
reduced manufacturing capacity or integration issues related to our
acquisition of the Cheetah product line, the loss of key

-9-


assembly subcontractors or other factors, our ability to produce and
ship our manufactured products and therefore our future results could
be materially adversely affected.

- We have recently completed, and we may pursue additional, acquisitions
of companies, product lines and technologies as part of our efforts to
enhance our existing products, to introduce new products and to
fulfill changing customer requirements. Acquisitions involve numerous
risks, including the disruption of our business, exposure to assumed
or unknown liabilities of the acquired target, and the failure to
integrate successfully the operations and products of acquired
businesses. Goodwill arising from acquisitions may result in
significant charges against our operating results in one or more
future periods. Furthermore, we may never achieve the anticipated
results or benefits of an acquisition, such as increased market share
or the successful development and sales of a new product. The effects
of any of these risks could materially harm our business and reduce
our future results of operations.

- The carrying value of certain of our intangible assets, consisting
primarily of goodwill related to our LoopCare software and Cheetah
product line acquisitions from Lucent Technologies, Inc. and Acterna,
LLC, could be impaired by changing market conditions. We are required
under generally accepted accounting principles to review our
amortizable intangible assets for impairment when events or changes in
circumstances indicate the carrying value may not be recoverable.
Goodwill is required to be tested for impairment at least annually.
Factors that may indicate that the carrying value of our intangible
assets may not be recoverable include a decline in stock price and
market capitalization and lower than anticipated cash flows produced
by such intangible assets. If our stock price and market
capitalization decline, or if we do not realize the expected revenues
from an intangible asset, we may be required to record a significant
charge to earnings in our financial statements during the period in
which any impairment of that intangible asset is determined.

- Our future sales in international markets are subject to numerous
risks and uncertainties, including local economic and labor
conditions, political instability including terrorism and other acts
of war or hostility, unexpected changes in the regulatory environment,
trade protection measures, tax laws, our ability to market current or
develop new products suitable for international markets, obtaining and
maintaining successful distribution and resale channels and foreign
currency exchange rates. Reductions in the demand for or the sales of
our products in international markets could adversely affect future
results.

- Our products are complex, and despite extensive testing, and may
contain defects or undetected errors or failures that may become
apparent only after our products have been shipped to our customer and
installed in their network or after product features or new versions
are released. Any such defect, error or failure could jeopardize our
relationships with our customers, resulting in substantial costs for
both the Company and our customers as well as the cancellation of
orders, warranty costs, product returns and legal actions that could
adversely affect our future results.

- We market and sell certain of our products, including our DigiTest and
Cheetah product lines, through domestic and international OEM
relationships. Our future results are dependent on our ability to
establish and maintain third party relationships with OEM as well as
other marketing and sales distribution partners. If, however, the
third parties with whom we have entered into such OEM and other
partnerships should fail to meet their own performance objectives,
customer demand for our products could be adversely affected, which
would have an adverse effect on our revenues.

- Demand for our products is driven by many factors, including the
availability of funding in customers' capital budgets. There is a
trend for some of our customers to place large orders near the end of
a quarter or fiscal year, in part to spend remaining available capital
budget funds. Seasonal fluctuations in customer demand for our
products driven by budgetary and other reasons can create
corresponding fluctuations in period-to-period revenues, and we
therefore cannot assure you that our results in one period are
necessary indicative of our revenues in any future period.

- The markets for some of our products are very competitive. Some of our
competitors may have greater technological, financial, manufacturing,
sales and marketing, and personnel resources than we have. As a
result, these competitors may have an advantage in responding more
rapidly or effectively to changes in industry standards or
technologies. Moreover, better financed competitors may be better able
to withstand the pricing pressures that increased competition may
bring. If our introduction of improved products or services is not
timely or well received, or if our competitors reduce their prices for
products that are comparable to ours, demand for our products and
services could be adversely affected. For further discussion, see
"Sales and Competition" section above.

- Generally, we sell our products either directly, or indirectly through
OEM channels and other means, to end-user telecommunications and cable
television providers. It is possible that our customers, as the result
of bankruptcy or other rationales for dismantling network equipment,
could attempt to resell our products. The successful development of
such a secondary market for our products by a third party could
negatively affect demand for our products, reducing our future
revenues.

- Our success depends on our ability to attract, retain and motivate the
key management and technical personnel necessary to implement our
business plan and to grow our business. Despite the adverse economic
conditions of the past several years, competition for certain specific
technical and management skill sets is intense. If we are unable to
identify and hire the personnel that we need to succeed, or if one or
more of our present key employees were to cease to be associated with
the Company, our future results could be adversely affected.

ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION.

OVERVIEW

Communication plays an integral part of our society; it is, in reality,
a necessity of life. Telecommunication services provide people with a means to
communicate, with people across the street and around the globe, through diverse
channels ranging from traditional wired telephone service to wireless telephones
to electronic means such as e-mail and other Internet-based offerings. As a
leading producer of network assurance and monitoring systems for wired networks,
our products permit service providers to supply their customers with consistent
and high quality telecommunications offerings, allowing, for example, telephone
companies to diagnose and assess problems within their networks and cable
operators to monitor the power supplies necessary to operate their systems.

As a result of the rapid technological, regulatory and economic
evolution of the telecommunications marketplace (which we define to include
cable television service) over the past several years, we believe that it is our
challenge, and our opportunity, to leverage our embedded base of customers and
dominant market position to address the testing and monitoring needs of new
system architectures by offering products addressing such needs that represent
relatively small incremental investments in customers' existing testing and
monitoring systems. We want to provide our customers with the ability to
seamlessly transition from one network to another with comparatively minimal
capital investments in existing testing solutions.

The recent downturn in the telecommunications industry revealed several
trends that we expect to continue to impact our business:

- incumbent telephone carriers continue to lose customers to smaller,
independent carriers which are not as heavily regulated;

- cable providers have taken the initial lead in the broadband service
market, primarily because cable modem technology was perfected before
DSL technology and because telephone providers are regulated much more
than cable companies; and

- both cable and telephone companies (as well as the providers of
satellite, wireless and other information mediums) are eager to market
the so-called "triple-play" of voice, data and video broadband
services.

The result of these trends thus far has been that incumbent telephone carriers
(especially the RBOCs) have considerably slowed their investments in plain old
telephone service (POTS) line capacity relative to their capital investment
patterns of the late 1990s through 2001; instead, some of these providers, from
which we derive a large percentage of our revenue, are focusing their capital
spending on next generation projects such as DSL service and
fiber-to-the-premises (FTTP). Capitalizing on their present technological
advantages, cable companies have aggressively marketed their broadband services;
in fact, due in part to the advent of wireless telephone service and
Internet-based services, such as Voice-over Internet Protocol (VoIP), cable
providers are well positioned to promote the utility of cable broadband service
over the need to maintain both wired telephone and cable services.

We continue to adapt to these and other changes in the marketplace,
changing the perception that we are solely the provider of an old-line legacy
incumbent testing system. As a result of our acquisition in 2003 of our Cheetah
cable product line, we believe that we have become the leading provider of
status monitoring products for the cable industry; including Services,
approximately 29% of our 2003 revenue was generated by cable product sales, a
significant increase from the 5% of our 2002 revenue generated by cable
offerings. Our recently consummated alliance with Alpha, the leading provider of
cable power management products, should position us to sustain our leading
position in the cable field in the wake of the recent adoption of the
standardized HMS and Data Over Cable Service Interface Specifications (DOCSIS)
protocols for cable modems that may in the future render our proprietary cable
hardware products obsolete. With respect to our telephony products, although we
do not predict that our sales of our core MCU products will reach the levels
seen in 2000, we are encouraged by recent MCU sales in conjunction with large
scale projects, most notably the building out of both POTS networks by
competitive service providers and DSL systems by the RBOCs. With regard to DSL,
we plan to market our DigiTest system as a tool to measure a network's capacity
to offer DSL service. We have also in the past several years placed a greater
emphasis on developing and marketing software applications that conform to
industry needs, such as DOCSIS and fiber-optic only networks.

The result of our expanded cable and software offerings and changes in
the industry generally is that our customer mix has changed and will continue to
change, a factor which we expect will make us much less susceptible to the
capital spending habits of a few select large customers. However,
notwithstanding our relative success in remaining profitable during the past
several years, we believe that there is still too much flux in the marketplace
to allow us to accurately predict the eventual direction that the
telecommunications industry will take, or how our business might fit within that
new model. Moreover, given the lower margins generated by our cable products
relative to our proprietary MCU and software offerings, changes in our product
mix may cause our overall profitability to decrease.

INDUSTRY AND MARKET TRENDS

In the past, consumers had little choice in the range of available
telecommunication services (which was limited primarily to hardwire telephone
lines) or the number of providers of such services (almost exclusively
restricted to incumbent local exchange carriers). This combination of limited
services and providers, coupled with governmental regulation of the industry,
meant that if consumers wanted telephone service, they bought it from the
company designated by the government at a price approved by the government.

We believe that the continuing evolution of the telecommunications
marketplace, driven by advances in technology as well as the deregulation of the
industry, among other factors, have resulted, and will continue to result, in
intense competition among telecommunications service providers. Many consumers
now have the ability to choose among a variety of comparable telecommunication
services offered by a number of different providers. Led by the adoption of The
Telecommunications Act of 1996, the deregulation of the industry has allowed
certain consumers to obtain local telephone service from either their incumbent
local exchange carrier, which in the old regulatory environment possessed the
exclusive right to provide that service, or by one or more competitive service
providers, which may actually provide telephone service over the network owned
by that same local exchange

-14-


carrier but at a lower cost. Moreover, consumers may choose from a growing list
of communications options that provide the same level of service once reserved
to the local telephone company. The proliferation of wireless telephone service,
for instance, now allows a consumer to place calls from nearly any location in
the United States, and from most parts of the world. Using VoIP, a person may
place a call from a computer either to another VoIP customer or to a hardwired
or wireless telephone number. As a result, the provision of telecommunication
services in certain markets today is highly competitive, with the industry in
general rapidly transforming from a highly regulated monopolistic model to more
of a free market model.

Although these evolutionary factors have adversely affected our
business to varying degrees over the past three years, we believe that it is
still too early to adequately assess the long-term effect of these changes on
the Company. Because our products are sold primarily to telephone and cable
television companies, of which there are still a relatively limited number, the
loss of any of our customers can translate into reduced demand for our
offerings, especially our test system and test access hardware products.
Conversely, the introduction of competition into the marketplace has helped to
bring new customers to us, including the increasing number of competitive
service providers which are building out new networks instead of leasing
capacity on incumbent carrier networks and cable companies which are expanding
or upgrading their systems to meet the increasing demand for broadband and
telephone services. Telephone companies, especially the RBOCs, have also been
attempting to meet the demand for broadband services, with the build-out of
their DSL networks, which in some instances has resulted in increased demand for
our MCU products in particular. The result, however, of the expansion of the
broadband market, will likely be the continued reduction in demand for POTS
service, potentially depressing overall MCU sales.

We are cautiously optimistic that the downturn in the
telecommunications industry, which began in early 2001 and persisted into 2003,
has begun to recede. The downturn was caused by a number of factors, including
the general slowdown of the U.S. and global economies during the period, network
overcapacity, constrained capital markets and financial difficulties among
certain telecommunication providers, especially CLECs whose business models did
not produce the profitability necessary to justify their significant ongoing
capital consumption, a problem due in part to continuing regulatory hurdles
during the downturn that impeded competitive access to the telecommunications
infrastructure. We are hopeful that recent trends in our customers' ordering
patterns, such as increased MCU orders in advance of expected digital loop
carrier system deployments in 2004, indicate a general recovery in the industry.

We benefited greatly from the increased capital spending of
telecommunication providers during the late 1990s and into 2000. As the RBOCs
and others built-out new and upgraded existing networks during the period,
tremendous demand for our products resulted in very high levels of
profitability. Although we remained profitable during the industry downturn that
followed, we analyzed during that period, and continue to analyze, our product
offerings relative to the needs of the marketplace. Over the past several years,
in addition to reorganizing our workforce, we have diversified our product
offerings both through our acquisitions of the LoopCare software and cable-based
Cheetah product lines and through our development of new products, especially
those aimed at the broadband test market, such as DigiTest EDGE. We believe that
our ongoing diversification efforts, some of which have had the secondary effect
of bringing new customers to the Company thus reducing our reliance on the
RBOCs, will strategically position us to compete in the evolving marketplace.

Complicating our ability to assess our market space in the
telecommunications industry is the uncertainty driven by the deregulatory
efforts of various government entities, especially at the Federal level.
Deregulation has actually resulted in the imposition of additional regulations
that affect certain telecommunications services and providers, including changes
to pricing, access by competitive vendors and other broad changes to data and
telecommunications networks and services. As the Federal Communications
Commission (FCC) and other government agencies continue to enact new or amend
existing regulations, especially relating to The Telecommunications Act of 1996,
our customers cannot always accurately interpret or predict the rules by which
they will be required to compete in the market place. Moreover, compounding
these regulatory issues are the current and expected legal challenges to the
FCC's authority to implement regulations or to the Act itself. These changes in
the regulation of the telecommunications industry in the United States have had
a major impact on our customers, especially on their pricing of services, and
may affect their deployment of future services. We do not believe that we can
accurately predict when these issues will be resolved, or that this deregulatory
effort will continue in the future.

Furthermore, competition in the telecommunications market, encouraged
and affected by these deregulatory efforts, has had the secondary effect of
resulting in the consolidation of many of the telecommunications service
providers. In some ways, we have benefited from the increased competition in the
industry; competition has brought more providers into the market that may need
our products to provide consistent and quality telecommunications services.
However, as a result of industry consolidations, we have and could in the future
experience disruption of our existing customer relationships, delays or loss of
customer orders and pricing pressures caused by the reduction in the number of
customers desiring our products, in turn causing decreased revenues and lower
net income. Consolidation and exit from the industry is especially a concern for
us regarding competitive service providers, to whom we sell a moderate volume of
our products. Many in the industry believe that the competitive service provider
market is overbuilt, and as a result is experiencing a process of consolidation
and closure. Moreover, many competitive service providers do not have a strong
financial position and have limited ability to access the public financial
markets for additional funding for growth and operations. Although we depend to
a great degree on our RBOC customers for our revenue (but even these large
customers are susceptible to consolidations), we are still affected by the
success of our competitive service provider customers. Once again, however, we
believe that it is too early to predict the course that industry consolidations
will take in the future, or how such consolidations might affect our revenues.

The most evident market trend to impact our results in the years from
2001 through 2003 compared to 2000 was the general slowdown in the build-out of
POTS networks by the RBOCs and other independent local exchange carriers. In the
years immediately preceding 2001, companies expanded their POTS line capacity at
the rate of approximately 5% per year. This line growth resulted in extremely
high demand for our MCU products. Beginning in 2001, however, a number of
factors converged to suppress the expansion of POTS networks. Perhaps the most
important factor was the declining demand for wired telephone service, or more
simply, "line loss"; in essence, telephone companies were, and still are, losing
more customer lines than they are adding. Line loss has resulted from a number
of trends, including competition from wireless telephone providers and the
reduction in the need for multiple telephone lines, driven in part by the
increasing popularity of DSL (which is normally accessed though a household's
primary

-15-


hardwire telephone line) and cable modems for broadband access to the Internet.
Although we do not believe that wireless service will entirely supplant the need
for wired telephone service, we do expect that wireless telephones, as well as
other alternatives to traditional telephones such as VoIP, will continue to
erode the demand for POTS service; the extent of such reduced demand, however,
is difficult to predict at this time. However, many cable operators also intend
to deploy VoIP, which may serve to stimulate additional sales of our cable
status monitoring products.

Although telephone companies are not expanding the capacity of their
POTS networks as aggressively as they once did, they are still investing in
their network infrastructure. Generally, the combination of increased
competition and reduced revenues in recent years has left the telephone
companies with less funds available for capital investment. We are encouraged,
however, by several trends, including the movement by competitive carriers to
build POTS networks rather than leasing network space from incumbent carriers;
additional POTS capacity may result in MCU sales. Furthermore, a majority of the
RBOCs have, at present, announced small increases in their capital budgets for
2004 over 2003 (although such increases are on average even less than 1%).
Rather than investing in POTS, however, increasing portions of these capital
budgets are being allocated to other projects, such as DSL rollouts, ATM
switches and FTTP projects. We have benefited from the DSL projects in
particular, such as SBC's DSL Footprint Expansion initiative, which have
resulted in increased demand for our MCU products.

If implemented on a large scale, FTTP projects, which would provide
broadband services through a direct fiber-optic link between a telephone
company's central office and the end user (i.e., individual households and
businesses), will reduce demand for our MCU products. Unlike traditional hybrid
networks in which our MCU products are deployed, fiber-optic systems can be
tested and managed with appropriate software (including variations of our
LoopCare software). We remain confident, however, that hybrid fiber-optic/copper
line networks will continue to be the medium through which the majority of POTS
services are delivered in the United States for the foreseeable future. Although
many of our telephone company customers are indicating an interest in FTTP
projects, it still is not clear that FTTP will be implemented on a large scale
basis. Given the size and breadth of the present hybrid networks, including the
billions of dollars invested in them, coupled with the billions of dollars
required to replace them with all fiber-optic lines, we believe that the copper
portion of the network will remain an important part of the telecommunications
system in the United States.

Unlike most of the existing telephone network, the hybrid fiber coaxial
(HFC) networks maintained by the cable television companies are capable of
providing broadband services with little additional capital investments. In
general, cable companies have been quite successful with their deployments of
high bandwidth Internet services. Since 1996, we have offered our legacy cable
(formerly LIGHTHOUSE) hardware products to cable companies for the status
monitoring of their networks; our recently acquired Cheetah hardware products
offer a similar proprietary system for the monitoring of hybrid fiber coax
distribution systems. The adoption of the HMS standard and, increasingly, the
DOCSIS standard for cable modems by a growing number of cable companies,
however, has the potential to eliminate the demand for certain of our
proprietary Cheetah head-end hardware products, and to reduce demand for other
proprietary Cheetah offerings.

OUR RESPONSES TO THESE INDUSTRY TRENDS

Although we are confident that we offer superior test system and status
and performance monitoring products, the evolution of the telecommunication and
cable networks requires us to constantly evaluate our product offerings relative
to the needs of the industry. We have taken a number of steps to attempt to
position the Company to take advantage of our leading position in certain of our
markets, including the continued expansion of our cable television network
monitoring and operations support system (OSS) software product lines, each of
which has served to expand our customer base.

Our commitment to the importance of growing our cable status monitoring
product line was confirmed by our February 13, 2003 acquisition of the Cheetah
product line from Acterna, LLC for a purchase price of $14.9 million. Consisting
of existing contractual relationships, products inventory, intellectual
property, software and related computer hardware, the acquired Cheetah assets,
coupled with the Company's existing LIGHTHOUSE platform, represent what we
believe to be the dominant monitoring products in the cable marketplace. With
the addition of the Cheetah product line, we have become the supplier of status
monitoring hardware and software to nearly every major cable company. We believe
our Cheetah products complement and augment our other cable product offerings
and strategically positions the Company to be the leading supplier of testing
equipment and software for the cable industry.

Moreover, we have taken a proactive approach to the increasing adoption
of the DOCSIS standards by cable providers. We have already begun to develop
DOCSIS-compatible monitoring hardware, which is expected to be generally
available by March 27, 2004. Additionally, in 2003, we entered into an agreement
with Alpha Technologies to be the exclusive supplier of IP-based DOCSIS status
monitoring equipment for Alpha power supplies used hybrid-fiber coax (HFC)
networks. By joining with Alpha, we have partnered with the primary provider of
power supply products to the cable industry to offer fully compatible and
integrated DOCSIS transponders. As cable companies continue to leverage their
growing DOCSIS-based HFC infrastructure to deliver voice, data and video
services through a single conduit, we believe that we are well positioned to
provide the range of quality assurance and testing products necessary to
maintain our leading position in the cable marketplace.

Along with our growing focus on the cable market, we have also
increased our emphasis on developing and marketing software solutions for
network assurance and testing. Given the increasing interest of the RBOCs in
FTTP projects and the importance of software products to cable monitoring
systems, we believe that our development of new software solutions will be an
important determiner of our future success. Our LoopCare software is already the
dominant OSS software for copper line networks. Because fiber-only networks
require primarily software solutions for network testing, we have actively
promoted our ability to adapt our existing LoopCare OSS to serve FTTP systems.
Although we believe that it is much too early to determine the extent to which
FTTP projects will be implemented, we will continue to analyze the capital
spending trends in the industry and will attempt to adjust our product offerings
accordingly.

From 2001 to 2003, we reorganized our internal structure to
de-emphasize existing hardware development efforts and, through our
acquisitions, added significant capability in software engineering. During that
period, we reduced our existing headcount from approximately 400 to 200, while
adding about 100 new employees as part of the LoopCare and Cheetah acquisitions.
Of the nearly 200 original positions eliminated, many related to hardware
engineering and production activities. Conversely, many of the

-16-


new employees are involved in software or system development. As a result of
these changes, we believe that we are now better equipped to develop the
software products that we believe will in the future comprise a large component
of the test assurance market.

Although software products generally generate higher margin returns for
us than our hardware products, the initial development costs of software
applications, coupled with the inherent problems with pricing software sold to
customers, can make it difficult to assess the potential profitability of a new
software product. Unlike our MCU products, which are comprised of proprietary
technology that requires little modification, unless we acquire proprietary
software, we must internally develop any new software products. Software
development is a relatively expensive process, especially considering the human
costs of such an undertaking. Moreover, the development of software can be a
lengthy process that prevents our personnel from engaging in other potentially
more productive activities. Pricing presents another challenge; because it is
customary in our industry to sell perpetual enterprise licenses that cover an
entire customer's operations, it can be difficult to assess at the time of sale
the exact price that we should charge for a particular license. Initial pricing
issues are somewhat lessened by the stream of revenue generated by the software
maintenance agreements we normally enter into with our software customers;
maintenance arrangements related to our LoopCare and Cheetah acquisitions in
particular have elevated the revenues and importance of Services business to our
future success.

Furthermore, the sales process for our software products, especially by
our RBOC customers, can be cumbersome. The increasing trend is for strict
business case scrutiny by RBOCs relating to software sales, and for evidence of
a shorter return on investment than was traditionally required to support a
software purchase. In addition, to ensure compatibility with their respective
networks, these customers can require significant periods of time to test our
software products prior to agreeing to purchase them. This delay, coupled with
the enterprise license nature of the software licenses that we typically offer,
can lead to what we call "lumpy" software sales, meaning that software sales in
one period are not necessarily indicative of future sales in the next period;
our software revenues can follow unpredictable patterns, as our products
represent primarily one-time purchases and gain the approval of our customers at
varying rates. As a result, although we are hopeful that our increased emphasis
on software products will position us to meet the needs of the changing
telecommunications marketplace, it is difficult to predict the market's
acceptance of our software offerings or the rate at which such products will
generate revenue for us.

We have placed this increasing emphasis on cable and software products
as an avenue to replace the revenue historically generated by our core MCU
products. As the life cycle for MCU products continues to mature, and certain
RBOCs and other customers focus their capital spending on network improvements
such as FTTP rather than hybrid networks, demand for our MCU products will
likely diminish. As a result, even though we are confident because of the
prominence of copper lines in telecommunications networks there will still be a
strong market for MCU products, we expect that in general, sales of MCU products
will decline over time. Notwithstanding this fact, we expect that MCU sales will
continue to comprise a significant portion of our revenues for the foreseeable
future.

Our DigiTest product line, introduced in 1999 following development
efforts with Lucent and Nortel, was originally targeted at Sprint for its
rollout of DSL service in several U.S. markets. DigiTest products initially
produced substantial revenues for us, as between 1999 and 2001 Sprint purchased
approximately $22 million in DigiTest test heads In 2001, however, Sprint
discontinued this project and curtailed its DigiTest purchases, resulting in a
material decline in overall DigiTest sales.

To increase DigiTest sales, we are actively marketing the system as a
replacement for, or upgrade to, the existing loop testing systems (LTS) employed
by the RBOCs to target problems in their POTS networks; we believe that DigiTest
is a good replacement product for the existing LTSs, which are decades old.
Replacement parts for them are no longer produced. Despite our marketing
efforts, however, except for small-scale deployments in certain selected
markets, the RBOCs have yet to allocate significant capital resources to LTS
replacement projects, and we expect that in the current competitive environment,
they will continue to attempt to utilize the existing LTS equipment as long as
possible. As a result, we expect this market to develop over a longer period of
time and on a more incremental basis than we originally anticipated.

We have taken a number of steps to increase our presence in the
telephony testing market space. Since its introduction, our POTS DigiTest test
head has undergone several significant developmental changes. With the
integration of the LoopCare software, which we acquired in 2001, with the
DigiTest hardware, we now offer a complete integrated testing system to smaller
customers such as competitive exchange carriers and international customers.
Furthermore, as a result of extensive research and development efforts in 2002
and 2003, we now offer our DigiTest EDGE product, which combines the reliability
of our DigiTest POTS testing system with our new Broadband Services Option (BSO)
test capability. The EDGE product is primarily targeted at the RBOC DSL market,
but does have applications in the competitive domestic and international
markets. We expect that once the DSL customer base of the RBOCs reaches a level
of maturity that supports higher measures of centralized testing, the EDGE will
compete favorably with similar offerings in the market. We remain hopeful that
demand for the EDGE product, combined with increasing opportunities for sales of
DigiTest POTS systems to competitive carriers and RBOCs for LTS replacement
projects, will represent a replacement revenue stream for declining MCU sales.

The continuing general trends of reduced MCU sales and increasing
software and cable-related product revenues, which were substantially augmented
by our recent acquisition of the Cheetah product line, has resulted in the
broadening of our customer base. Although we still rely on the RBOCs for a large
portion of our revenues, the percentage of our overall revenues generated from
RBOC customers has dropped from 71% in 2001 and 77% in 2002 to 56% in 2003. This
decrease is due in part to the reduced capital spending of the RBOCs. More
importantly to us, however, has been our increasing sales to new customers,
primarily cable companies and CLECs. As our cable monitoring products become
more fully entrenched, CLECs build out their own networks, and sales of our
software to new customers increase, we expect that our dependence on the RBOCs
for a large portion of our revenue will continue to decrease in 2004 and beyond.

Because our cable products generate lower margins for us than our
proprietary MCU and software offerings, an increase in the percentage of our
sales of cable-related products relative to our traditional products will result
in lower profitability. Furthermore, as consolidations within the cable industry
and the adoption of the DOCSIS standards have caused and could continue to cause
pricing pressure as competitors lower product pricing, our revenues have been
and may continue to be adversely affected. Although we are developing
DOCSIS-compatible hardware and our relationship with Alpha is one that we
believe will prominently position us to succeed in the marketing of DOCSIS
products, these DOCSIS products will likely generate lower margins than have
historically been generated by our proprietary technology. As a result, as our
business shifts from our higher margin proprietary products to lower

-17-


margin cable offerings and standardized products for which we have competition,
we will need to sell greater volumes of our products to maintain our
profitability.

Even with the adoption of DOCSIS by many cable providers, we believe
that there still is value in our proprietary Cheetah status monitoring systems,
especially for those customers who have already made significant investments in
our cable products. Nevertheless, the further evolution of cable industry
standards could and likely will eliminate the need for some of these proprietary
products.

Because of our historical inability to effectively market our products
internationally and the incompatibility of some of our products with the various
technological standards employed abroad, we do not expect that our revenues from
international sources will appreciably increase in the near future. In response,
during 2003, we reduced our international marketing staff. Since our MCU
products are designed to meet the specifications of the hybrid copper-fiber
network in the United States, they have limited applications in the
international markets. Our LoopCare software products, however, do have utility
for international customers. Through our original equipment manufacturer (OEM)
relationship with Lucent, our LoopCare products have been sold internationally
in conjunction with purchases of Lucent hardware. Furthermore, the Company
enjoys a stream of software maintenance revenue from international sources. Our
DigiTest and Cheetah product lines are also marketed internationally through OEM
relationships. As demand for cable service internationally increases, we believe
that our cable products in particular may offer an avenue to increasing our
international sales, as worldwide cable standards do not differ materially from
those supported by our products. In the short term, the success of our DigiTest
and Cheetah offerings will primarily be dependent on the efforts of our OEM
partners and in the competitiveness of our OEM pricing model.

In addition to the industry and product trends that we have already
discussed, our operating results have fluctuated and may continue to fluctuate
from time to time as a result of various other factors, including the timing of
orders from, shipments to, and acceptance of software by, the RBOC customers and
significant independent telephone companies. This timing is particularly
sensitive to various business factors unique to each of our larger customers,
including their relationships with various organized labor groups and a
continuing tendency to place large orders for shipment of hardware and software
toward the end of a quarter, which may result in orders placed in one quarter
not being filled until the next period. In addition, the markets for some of our
products, such as LoopCare and DigiTest, are highly competitive. Due to the
rapidly evolving market in which these products compete, additional competitors
with significant market presence and financial resources could further intensify
the competition for these products.

We believe that the changes outlined above and others within the
telecommunications marketplace, industry consolidation, as well as our
continuing efforts to expand our customer base and product offerings, have
required us to grant more favorable terms to some of our customers. Furthermore,
certain customers have consolidated product purchases among their various
divisions, translating into large bulk orders for our products. There is a
continuing trend, which is in part a result of our discounting programs, for
these customers to place large bulk orders for large quantities of hardware and
software products. Although we will continue to strive to meet the demands of
our customers, which include delivery of quality products at an acceptable price
on acceptable terms, we can provide no assurance that we will be successful in
negotiating acceptable terms and conditions with our customers or that these
continuing efforts by our RBOC customers to consolidate their inventory and
product procurement systems will not cause fluctuations or delays in our order
patterns.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

Our financial statements are prepared in conformity with accounting
principles generally accepted in the United States of America. The application
of certain of these accounting principles are more critical than others in
gaining an understanding of the basis upon which our financial statements have
been prepared. We deem the following accounting policies to involve critical
accounting estimates.

Revenue Recognition

We market and sell test system hardware and related software to the
telecommunications and cable television industries. The Company follows Staff
Accounting Bulletin (SAB) 104, "Revenue Recognition" for hardware and software
sales. This bulletin requires, among other things, that revenue should be
recognized only when title has transferred and risk of loss has passed to a
customer with the capability to pay, and that there are no significant remaining
obligations of the Company related to the sale. The bulk of our hardware sales
are made to RBOCs and other large customers. Terms of these hardware sales are
predominantly FOB shipping point. Revenue is recognized for these customers upon
shipment against a valid purchase order. The timing of revenue recognition may
require the judgment of management. We reduce collection risk by requiring
letters of credit or other payment guarantees for significant sales to new
customers and/or those in weak financial condition.

For software perpetual license fee and maintenance revenue, we follow
not only SAB 104, but also the AICPA's Statement of Position (SOP) 97-2,
"Software Revenue Recognition," and Emerging Issues Task Force (EITF) Issue
00-21, "Accounting for Revenue Arrangements with Multiple Deliverables." These
statements require that software license fee revenue be recorded only when
evidence of a sales arrangement exists, the software has been delivered, and a
customer with the capacity to pay has accepted the software, leaving no
significant obligations on the part of the Company to perform. We require a
customer purchase order or other written agreement to document the terms of a
software order and written, unqualified acceptance from the customer prior to
revenue recognition. In certain limited cases, however, agreements provide for
automatic customer acceptance after the passage of time from a pre-determined
event and we have relied on these provisions for an indication of the timing of
revenue recognition. In isolated cases for orders of custom software, or orders
that require significant software customization, we employ contract accounting
using the percentage-of-completion method, whereby revenue is recognized based
on costs incurred to date compared to total estimated contract cost. The revenue
for orders with multiple deliverables such as hardware, software and/or
installation or other services may be separated into stand-alone fair values if
not already documented in the purchase order or agreement and where list prices
or other objective evidence of fair value exists to support such allocation, in
accordance with the provisions of EITF Issue 00-21. Revenue will not be
recognized for any single element until all essential elements are delivered and
accepted.

Our LoopCare and other software customers usually enter into separate
agreements for software maintenance upon expiration of the stated software
warranty period. Maintenance agreements include software upgrades and bug fixes
as they become available;

-18-


however, newly developed features must be purchased separately. Post-warranty
maintenance for new features is either included under the current maintenance
agreement without additional charge, and is considered in the maintenance
agreement fees, or is separately charged upon expiration of the warranty.
Depending upon the timing of the enhancement purchase and the length of the
maintenance agreement, we must evaluate whether or not a portion of a perpetual
right to use fee should be treated as post contract support to be deferred and
recognized over the remaining life of the maintenance agreement.

Software maintenance revenue is recognized on a straight-line basis
over the period the respective arrangements are in effect.

Revenue recognition, especially for software products, involves
critical judgments and decisions that can result in material effects to reported
net income.

Intangible Assets and Goodwill

We had net intangible assets and Goodwill of $71.6 million at December
31, 2003 primarily resulting from the acquisitions of the LoopCare and Cheetah
product lines in September 2001 and February 2003, respectively. In connection
with these acquisitions, we utilized the transitional guidance of Statement of
Financial Accounting Standards (SFAS) No. 141, "Business Combinations" and SFAS
No. 142, "Goodwill and Other Intangible Assets," which were issued in July 2001.
SFAS No. 141 requires that the purchase method of accounting be used for all
business combinations initiated after June 30, 2001 and that goodwill, as well
as any intangible assets believed to have an indefinite useful life, shall not
be amortized for financial reporting purposes. An independent valuation
consultant assisted the Company in identifying and valuing both the LoopCare and
Cheetah intangible assets.

In connection with the assets acquired in the LoopCare transaction,
intangible assets of $45.8 million were identified. Capitalized software valued
at $7.3 million was determined to have a definite useful life of five years and
is being amortized over that period. Also identified were intangible assets
related to the LoopCare trade name of $1.3 million, LoopCare base software of
$5.2 million, and post-warranty service agreements of $32.0 million. Because of
the longevity of the LoopCare trade name, the fact that over 80% of the original
base software code that was developed in the 1970's is still in use in the RBOCs
today and strong sales and resultant cash flows are expected indefinitely into
the future, both of these related identified intangible assets were determined
to have indefinite useful lives. With regard to the post-warranty service
agreements, these arrangements have been in place for many years and we believe
that these annual agreements will be renewed into perpetuity due to their
critical importance in the operations of the customers. We have entered into new
maintenance contracts for 2004 with all four RBOC customers. We intend to
maintain fixed fee arrangements for all maintenance contracts. Therefore, we
believe that the non-amortizing characteristics of these intangible assets will
be preserved. However, in the event negotiations would result in substantially
less revenue to us than the current fixed fee agreements, the current fair value
of these maintenance service agreements may be determined to be less than the
$32.0 million carrying value, perhaps materially so, resulting in a non-cash
charge against operating income in 2004 or beyond and/or commencement of
amortization of the remaining fair value over its then determined useful life. A
similar analysis of the fair value of the maintenance service agreements would
be required if any of our RBOC customers would terminate or indicate a definite
life for their respective maintenance service agreement for any reason.

In the Cheetah acquisition, intangible assets of $10.5 million were
identified, of which base software valued at $2.9 million and proprietary
technology valued at $1.0 million were determined to have a definite useful life
of ten years and are being amortized over that period. Sales order backlog
acquired in the transaction was valued at $0.5 million and is substantially
amortized at December 31, 2003. This product line has three or four dominant
customers who have purchased and supported Cheetah products for many years. This
provides a dominant market position for this product line. As a result, the
remaining identified intangible assets of customer base valued at $5 million and
"Cheetah" trademark valued at $1.0 million have been determined to have an
indefinite useful life and, along with goodwill of $3.3 million, are not being
amortized.

As of January 1, 2002, we fully adopted the provisions of SFAS No. 142.
We have determined that we have only one operating unit and have completed tests
for goodwill impairment as of December 31, 2003 by comparing the aggregate
market value of the Company's stock with our book carrying value, including
goodwill. These tests indicated that there was no impairment of the goodwill
carrying value. From time to time, the market value of our stock temporarily
declined to an amount below the book carrying value. We believe that these
instances were reflective of then current conditions in the telecommunications
and general markets. However, future changes in circumstances, including a
sustained decline in the aggregate market value of our stock, could necessitate
a reconsideration of whether an impairment of goodwill carrying value has
occurred, requiring an alternate testing of our fair value under guidance of
SFAS No. 142. In that event, impairment in value up to the full amount of the
goodwill could be determined, resulting in an impairment loss to be recorded in
our financial statements.

All other intangible assets were tested for impairment of carrying
value as of December 31, 2003 using assumptions and techniques employed in the
original valuation and following the guidance of SFAS No. 144, "Accounting for
the Impairment or Disposal of Long-Lived Assets." Specifically, the sum of the
projected future cash flows to be derived from the LoopCare developed product
software was compared with the net book carrying value. The impairment test for
non-amortizable intangible assets other than goodwill consisted of a comparison
of the estimated fair value with carrying amounts. The values of the LoopCare
trade name and Cheetah trademark were measured using the relief-from-royalty
method and discounted cash flow analyses were employed to test the value of the
LoopCare base software and post warranty maintenance service agreements and the
value of the Cheetah customer base. These tests indicated that none of the
intangible assets had impairment in carrying value. The Company plans to retest
these assets annually as of December 31 or more frequently if events or changes
in circumstances indicate that assets might be impaired.

This testing relative to impairments involves critical accounting
estimates. We relied upon our financial plan for 2004 and best estimates of
revenues and cash flows for later years in measuring current values; however,
these expectations may not be realized and future events and market conditions
might indicate material impairment of value that could result in material
charges to net income. Such a future situation would not, however, in and of
itself affect our cash flow or liquidity.

Inventory Valuation

We utilize a standard cost system that approximates first-in, first-out
costing of the products. Standards are monitored monthly and changes are made on
individual parts if warranted; otherwise standard costs are updated on all parts
annually, normally in November of each year. We evaluate our inventories on a
monthly basis for slow moving, excess and obsolete stock on hand. The

-19-


carrying value of such inventory that is determined not to be realizable is
reduced, in whole or in part, by a charge to cost of sales and reduction of the
inventory value in the financial statements. The evaluation process, which has
been consistently followed, relies in large part on a review of inventory items
that have not been sold, purchased or used in production within a one-year
period. Management also reviews, where appropriate, inventory products that do
not meet this threshold but which may be unrealizable due to discontinuance of
products, evolving technologies, loss of certain customers or other known
factors. As a result of this comprehensive review process, an adjustment to the
reserve for slow moving and obsolete inventory is normally made monthly.
Inventory identified as obsolete is also discarded from time to time when
circumstances warrant.

Inventory realization is considered a critical accounting estimate
since it relies in large part on management judgments as to future events and
differing judgments could materially affect reported net income.

Due to the decline in sales in 2001 and 2002, slow moving inventory
increased in volume but included many items believed to be active inventory for
active products. This trend resulted not only from slower sales but also from
the strong effort to decrease inventory levels that resulted in reduced
manufacturing activity and parts usage. The expense for slow moving and obsolete
inventory was $0.3 million, $2.5 million and $0.2 million for 2001, 2002 and
2003, respectively, while the valuation reserves increased slightly in 2001,
increased $1.2 million in 2002 and decreased by $0.9 million in 2003 to a
balance of $1.5 million at December 31, 2003. Inventory physically scrapped was
$0.3 million, $1.3 million and $1.1 million in 2001, 2002 and 2003,
respectively.

Income Taxes

We follow the provisions of SFAS No. 109, "Accounting for Income
Taxes," in reporting the effects of income taxes in our consolidated financial
statements. Deferred tax assets and liabilities are determined based on the
"temporary differences" between the financial statement carrying amounts and the
tax basis of assets and liabilities using enacted tax rates in effect in the
years in which the differences are expected to reverse. As of December 31, 2003,
we had recorded net deferred tax assets of $1.1 million, comprised of $1.4
million resulting from carry forward of state net operating losses, other tax
assets of $2.6 million and deferred tax liabilities of $2.9 million. Total net
deferred tax assets decreased by $1.2 million in 2003 due to the amortization of
intangible assets for tax purposes creating deferred tax liabilities. Net
deferred tax assets are expected to continue to decrease in future years. The
timing of the reversal of the deferred tax liabilities and to a large extent the
deferred tax assets are dependent upon uncertain future events and cannot be
assumed to occur in the same tax years.

The state net operating loss carryforward relates primarily to tax
losses arising in 2000, a year in which the Company had significant tax
deductions arising from stock option exercises. The majority of this
carryforward is subject to state laws that allow a 20-year carry forward period
with a $2.0 million limit on deductions in each year. Future realization of the
recorded tax assets resulting from both timing differences and carryforward
losses is dependent upon the existence of sufficient taxable income in future
years.

SFAS No. 109 requires that a valuation allowance be recorded against a
deferred tax asset when it is more likely than not that some or all of that
deferred tax asset will not be realized and, accordingly, a valuation allowance
of $0.5 million has been recorded against the state tax carryforward deferred
tax assets. We believe that the recent business climate in the
telecommunications industry is not permanent and that the net balance of state
tax carryforward and other tax assets will more likely than not be realized in
future years, especially for federal tax assets that comprise 87% of the
non-carryforward amounts. The Company had federal taxable income in 2003 and
expects to have federal taxable income in future years.

Warranty

We provide warranty coverage on our various products. Terms of coverage
range from up to one year on software to two to five years for hardware
products. We review products returned for repair under warranty on a quarterly
basis and adjust the accrual for future warranty costs based upon cumulative
returns experience. We also evaluate special warranty problems for products with
high return rates to correct the underlying causes and, where deemed necessary,
to provide additional warranty expense for expected higher returns of these
products. Warranty costs associated with software sales are also accrued based
on the projected hours to be incurred during the warranty period (normally three
months). The accounting for warranty costs involves critical estimates and
judgments that can have a material effect on net income. The warranty accrual
increased by $1.0 million in 2001 and decreased by $0.1 million in 2002. In
2003, we recorded an acquisition entry of $0.2 million to provide an accrual for
pre-acquisition warranty costs of Cheetah products. The overall warranty accrual
increased by $0.2 million in 2003 to a balance of $2.2 million at December 31,
2003.

These areas involving critical accounting estimates are periodically
reviewed and discussed with the Audit Committee of our Board of Directors.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2003 COMPARED TO THE YEAR
ENDED DECEMBER 31, 2002

Revenue

Revenue for the year ended December 31, 2003 was $65.1 million, an
increase of $6.5 million or 11.1% over the revenue of $58.6 million recorded for
the year ended December 31, 2002. The increase in revenue resulted primarily
from the February 2003 acquisition of the Cheetah product line. This new revenue
was partially offset by lower LoopCare software sales and reduced MCU and
DigiTest sales.

Sales of the MCU product line in 2003 decreased by $2.7 million, or
9.5%, from the results of the previous year. This decrease in sales, which was
primarily associated with reduced sales to two RBOC customers, was partially
offset by strong sales to AFC and another original equipment manufacturer. As
the life cycle for the MCU product continues to mature, there is an increasing
possibility that customer requirements for certain legacy MCU products will be
satisfied. The MCU product line accounted for approximately $25.4 million, or
39.0%, of our 2003 revenue.

Overall sales of cable hardware and software products were $17.4
million in 2003, or 27% of 2003 revenue, of which $13.6 million was contributed
by Cheetah hardware and CheetahNet(TM) (formerly NetMentor(TM)) software
products and $3.8 million were attributable to the Company's legacy cable status
monitoring products (formerly LIGHTHOUSE(R)). The legacy cable product sales

-20-


were $3.1 million in the year earlier period.

Sales of the Company's DigiTest product line, including $1.2 million of
related LoopCare software sales, decreased in 2003 by $1.7 million, or 20.5%,
from our results for 2002. This decrease was primarily the result of both the
inclusion in our 2002 results of the completion of a major centralized test head
replacement and augmentation program by an RBOC and lower sales to Nortel
Networks in 2003. DigiTest sales were made to each of the RBOCs in 2003 for
modest loop test system initiatives and to both independent and competitive
carriers for new installations and expansions of existing DigiTest systems.
DigiTest product sales in 2003 represented $6.6 million, or 10.1%, of our 2003
revenues.

Sales of stand-alone LoopCare software products in 2003 were $3.4
million, a decrease of $4.1 million or 54.7% from the prior year. Revenues for
2003 were affected by a lack of large dollar RBOC sales and a slowdown in
international orders. In 2004, we expect that our LoopCare sales will increase
due to expanded RBOC rollout of existing LoopCare features, as well as new
feature development in the areas of DSL, VoIP, and FTTP technology, which we
anticipate will energize software sales. Stand-alone LoopCare software product
sales in 2003 were 5.2% of our total revenue for the year.

Revenue from services, which includes installation oversight and
project management services provided to RBOC customers and fees from LoopCare
and Cheetah software maintenance arrangements, was $12.3 million in 2003,
representing 18.9% of our total revenue for the year. Services revenue for 2003
increased $2.0 million over the results for 2002, due primarily to the addition
of $1.2 million in CheetahNet maintenance fees and an increase or $0.6 million
in LoopCare software maintenance largely as a result of additional maintenance
fees related to new sales of software features.

We experienced some improvement in our core equipment markets in the
latter part of 2003 but remain uncertain as to continuing strength in this area
in the foreseeable future as key customers are expected to continue to restrict
their capital budgets. In 2003, we introduced our next generation DigiTest EDGE
test head for the evolving broadband network and continue to invest in research
to develop new and improved products to stimulate demand for our hardware and
software products. Our recently-acquired Cheetah product line was successful in
offsetting the current weakness in our traditional MCU and related equipment
product lines while complementing and strengthening the Company's legacy cable
products.

Gross Profit

Gross profit for 2003 was $36.0 million compared to $33.0 million for
2002, representing an increase of 9.1%. Gross profit as a percentage of revenue
decreased to 55.3% for 2003 compared to 56.3% for 2002. The increase in gross
profit resulted primarily from the overall higher sales levels which in turn
were primarily related to the Cheetah products that we acquired in 2003. The
decrease in gross margin as a percentage of sales resulted in large part from
lower sales of higher margin MCU and DigiTest hardware and LoopCare software,
with such sales being substantially replaced by the addition of lower margin
Cheetah cable product sales. Amortization expense of $0.9 million associated
with the Cheetah acquisition also negatively affected margins in 2003; this
expense included $0.5 million of amortization of purchased sales order backlog
which was substantially amortized at December 31, 2003. Partially offsetting
these negative factors was $2.3 million in reduced expense for slow moving and
obsolete inventory compared to 2002.

Selling and Marketing Expenses

Selling and marketing expenses consist primarily of personnel costs as
well as commissions and travel expenses of direct sales and marketing personnel,
and costs associated with various promotions and related marketing programs.
Selling and marketing expenses for 2003 was $9.4 million, or 14.4% of revenue,
compared to $8.8 million, or 15.0% of revenue in 2002. This increase of $0.6
million, or 6.8%, is attributable to the addition of $1.4 million in expenses as
a result of the Cheetah acquisition and higher expenses in other areas of the
business including $0.4 million for consulting and evaluation costs, offset, in
part, by cost reductions largely associated with budget tightening, such as $0.6
million for salaries and wages, $0.3 million for commissions and $0.2 million
for travel expenses.

General and Administrative Expense

General and administrative expenses consist primarily of personnel
costs for finance, administrative and general management personnel as well as
accounting, legal and insurance expenses. General and administrative expenses
for 2003 were $7.0 million, or 10.8% of revenue, compared to $5.5 million, or
9.4% of revenue for 2002. The increase of $1.5 million, or 27.3%, is
attributable primarily to the addition of $0.9 million in expenses as a result
of the Cheetah acquisition, including a $0.5 million provision for bad debts.
General and administrative expenses also increased due to higher business
insurance costs of $0.3 million and legal and professional fees of $0.2 million.

Research and Development Expenses

Research and development expenses consist primarily of personnel and
other costs associated with the development of new products and technologies,
including DigiTest products, next generation Cheetah hardware and software and
LoopCare software features, as well as the improvement of existing products.
Research and development expenses for 2003 were $14.9 million, or 22.9% of
revenue, compared to $13.8 million, or 23.6%, of revenue for 2002. The $1.1
million increase is attributable primarily to the addition of $2.7 million in
expenses related to the Cheetah acquisition, consisting largely of salaries and
benefits. The Cheetah expenses were offset in part by cost reductions in other
areas of the business including a $1.5 million savings in salaries and benefits
brought about largely by a reduction in work force at the beginning of the
fourth quarter of 2002. The Company expenses research and development costs as
they are incurred.

Other Income

Other income, which consisted primarily of interest income, was $0.4
million for 2003 compared to $0.7 million for 2002. The decrease of $0.3
million, or 42.9%, is primarily attributable to both a decrease in funds
available for investment resulting from the $14.3 million Cheetah acquisition in
February of 2003 and to the current low market yields on short term interest
bearing investments.

-21-


Provisions for Income Taxes

The Company's effective tax rate was 38.0% of income before income
taxes in both 2003 and 2002.

Net Income and Earnings Per Share

Net income for the year ended December 31, 2003 was $3.1 million
compared to $3.4 million for the year ended December 31, 2002, a decrease of
$0.3 million or 8.8%, due to a small compression of margin, including the effect
of acquisition-related intangible asset amortization. As a percentage of
revenue, net income for 2003 decreased to 4.8% from 5.7% in 2002.
Correspondingly, diluted earnings per common share of $0.24 for 2003 decreased
by 4.0%, or $0.01, from the $0.25 earned in 2002. Diluted weighted average
shares of common stock and equivalents outstanding were 13,312,597 in 2003
compared to 13,313,676 in 2002.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2002 COMPARED TO THE YEAR
ENDED DECEMBER 31, 2001

Revenue

Revenue for the year ended December 31, 2002 was $58.6 million, and was
$23.6 million or 28.8% lower than our revenue of $82.2 million for the year
ended December 31, 2001. The decrease in revenue resulted primarily from further
erosion in unit volume sales of traditional MCU and DigiTest system products,
partially offset by an increase in LoopCare software sales and maintenance
services. LoopCare products, however, were only available for sale during the
final three months of 2001. Sales of our MCU product line in 2002 decreased by
approximately $27.7 million, or 49.8%, from the results of the previous year.
This decrease in sales was across the board among our RBOC customers and was
primarily associated with slowdowns in RBOC capital spending programs to upgrade
DLC systems. The MCU product line accounted for approximately 47.8% of 2002
revenue.

Sales of the Company's DigiTest product line in 2002, including $0.6
million of LoopCare software, decreased by approximately $3.9 million, or 33.0%,
from the results of the year ended December 31, 2001. This decrease in DigiTest
sales was primarily the result of decreased direct shipments to Sprint USA
during 2002 as a result of the discontinuation of Sprint's ION project and to
reduced shipments to Nortel Networks and Choice One Communications. The declines
from these customers were offset in part by a major centralized test head
replacement and augmentation program at an RBOC. DigiTest sales accounted for
approximately 13.6% of 2002 revenue.

Sales of stand-alone LoopCare software products in 2002 were
approximately $7.5 million, representing 12.8% of total revenue for the year,
and were made primarily to two RBOC and various international customers. Gross
margins on the LoopCare product line business are substantially higher than
other product lines of the Company, and the resulting impact on earnings was
material. The Company acquired the LoopCare product line on September 30, 2001;
therefore, 2002 included twelve months of LoopCare operations while 2001
included only three months.

Services revenues were approximately $10.3 million in 2002, or 17.7%,
of our total revenue. Services revenues increased $5.7 million in 2002 over the
results of the previous year due to the inclusion of LoopCare maintenance fees
in 2002 for twelve months compared to the three months included in our 2001
results.

Sales of the Company's LIGHTHOUSE (now CheetahLight) cable status
monitoring system increased slightly in 2002 to $3.1 million, representing 5.3%
of total revenue. Strong sales to AT&T Broadband were mostly offset by reduced
sales to other cable service providers.

Gross Profit

Gross profit for 2002 was $33.0 million compared to $46.2 million for
2001, a decrease of $13.2 million, or 28.6%, from the previous year. Gross
profit as a percentage of revenue increased to 56.3% for 2002 compared to 56.2%
for 2001. The overall decrease in gross profit resulted primarily from the
decreased sales levels. Despite the decline in revenue from 2001, gross margin
in 2002 as a percentage of sales remained level due to several offsetting
factors including increased costs per unit sold due to substantially lower
hardware production, the nature of the product mix of hardware sales during 2002
compared to 2001 and a net increase in slow moving and obsolete inventory and
warranty costs of approximately $1.2 million in 2002. These higher costs were
offset, however, by changes in the product mix brought about by the acquisition
of the LoopCare product line on September 30, 2001. LoopCare products, which
enjoy higher gross margins than those earned historically on our other products,
contributed 26.3% of sales revenue in 2002 compared to 5.4% in 2001.

Selling and Marketing Expenses

Selling and marketing expenses for 2002 were $8.8 million, or 15.0% of
revenues, compared to $9.2 million, or 11.1% of revenues for 2001. This decrease
of $0.4 million, or 4.3%, is due primarily to reduced commissions associated
with lower sales levels, and cost reductions in the areas of test and evaluation
units, advertising, meetings and seminars and related marketing activities,
partially offset by higher salaries and consulting expenses.

General and Administrative Expenses

General and administrative expenses for 2002 were $5.5 million, or 9.4%
of revenue, compared to $4.8 million, or 5.9% of revenues for 2001. This
increase of $0.7 million, or 13.7%, is primarily attributable to increases in
outside professional fees, general insurance and salaries and wages, with the
increase in salaries and wages largely related to the LoopCare acquisition.

Research and Development Expenses

Research and development expenses for 2002 were $13.8 million, or 23.6%
of revenue, compared to $12.4 million, or 15.1% of revenue for 2001. This
increase of $1.4 million was due to an increase of $3.3 million, primarily
salaries, wages and rent expense attributable to the LoopCare product line in
Bridgewater, New Jersey, which was in operation for only three months in 2001.
These increases were offset in part by reductions in other salaries, wages and
benefits, travel and materials and supplies brought about in large part by a
reduction in work force at the beginning of the fourth quarter of 2002 for which
the Company recorded a pre-tax charge of $0.2 million.

-22-


Other Income

Other income, which consisted primarily of interest income, was $0.7
million for 2002 compared to $2.8 million for 2001. The decrease of $2.1
million, or 75.2%, is primarily attributable to a decrease in funds available
for investment resulting from the $62 million LoopCare acquisition in the fourth
quarter of 2001 and to the current low market yields on short term interest
bearing investments.

Provisions for Income Taxes

The Company's effective tax rate for 2002 was 38.0% of income before
income taxes, compared to a 38.6% rate in 2001.

Net Income and Earnings Per Share

For the year ended December 31, 2002, net income was $3.4 million
compared to $13.7 million for the year ended December 31, 2001, a decrease of
$10.3 million, or 75.5%. Diluted earnings per common share of $.25 for 2002
decreased by 75.5%, or $.77, from the $1.02 earned in 2001. Diluted weighted
average shares of common stock and equivalents outstanding were 13,313,676 in
2002 compared to 13,412,037 in 2001. The decrease in the diluted weighted
average shares of common stock and equivalents outstanding is primarily the
result of a reduction in the dilutive effect of outstanding stock options
related to the decrease in weighted average share price of the Company's common
stock. As a percentage of revenues, net income for 2002 decreased to 5.7% from
16.6% in 2001.

CHEETAH ACQUISITION

On February 13, 2003, we acquired certain assets and assumed certain
liabilities of the Cheetah Status and Performance Monitoring Product Line from
Acterna, LLC for approximately $14.3 million in cash. We also capitalized
acquisition related costs of approximately $0.6 million for a total cost of
approximately $14.9 million. The transaction provided for an earnout to be paid
in the first half of 2004 of up to $2,400,000 based on certain 2003 performance
targets. The current calculation indicates that amounts due under this provision
are immaterial. The acquired assets consisted principally of existing sales
order backlog, product inventory, intellectual property, software and related
computer equipment, while the assumed liabilities principally related to
deferred software maintenance, warranty and other obligations. The $14.3 million
due at closing and related acquisition expenses were paid from available cash
and short-term investments. We believe that the acquired product line will
complement our existing cable offering and position the Company as a leading
supplier of testing equipment and software for the cable industry. The
acquisition was recorded under the purchase method of accounting and
accordingly, the results of operations of the acquired product line from
February 14, 2003 forward are included in our consolidated financial statements.
The purchase price remains subject to change pending agreement between the
parties regarding the earn-out provision and post closing purchase price
adjustments.

LIQUIDITY AND CAPITAL RESOURCES

We had working capital of $65.9 million as of December 31, 2003, a
decrease of $7.7 million or 10.5% from the $73.6 million of working capital as
of December 31, 2002. The decrease in working capital is largely a result of the
$14.9 million expended for the Cheetah acquisition plus capital expenditures of
$2.8 million that exceeded net income before depreciation and amortization of
$7.9 million and the long-term deferrals of income taxes of $1.3 million.
Significant changes in the composite elements of working capital during 2003
include a $5.1 million decrease in inventories partially offset by a $1.7
million increase in accounts receivable-trade, with both factors due in part to
strong sales in the fourth quarter attributable to the year-end budget funds
availability of telecommunications providers. Overall, we generated cash from
operating activities of $13.0 million in 2003. As of December 31, 2003, the
Company had $48.7 million of cash, cash equivalents and short-term investments
that are unrestricted and available for corporate purposes, including
acquisitions and other general working capital requirements.

The Company has in place a five-year $25.0 million Unsecured Revolving
Credit Facility (the "Facility") with a bank. Under the terms of the Facility,
the proceeds must be used for general corporate purposes, working capital needs,
and in connection with certain acquisitions. The Facility contains certain
standard covenants with which we must comply, including a minimum fixed charge
ratio, a minimum defined level of tangible net worth and a restriction on the
amount of capital expenditures that can be made on an annual basis, among
others. A maximum leverage ratio restricts our total borrowings to approximately
$18.7 million during the first quarter of 2004. Commitment fees are payable
quarterly at an annual rate of 0.25% of the unused commitment. The Facility was
amended in February 2003 in connection with our acquisition of the Cheetah
product line to adjust the determination of base net worth. As of December 31,
2003 and currently, there are no outstanding borrowings under the Facility, and
we are in compliance with all debt covenants. We do not anticipate any
short-term borrowings for working capital as we believe our cash reserves and
internally generated funds will be sufficient to sustain working capital
requirements for the foreseeable future.

We made capital expenditures of $3.5 million, $1.8 million and $2.8
million in the three years ended December 31, 2001, 2002 and 2003, respectively.
Our 2003 expenditures were primarily related to providing facilities, office and
computer equipment and test fixtures for the new, leased Cheetah facility in
Sarasota, Florida. Expenditures in 2002 included the acquisition of land
adjacent to the Company's current manufacturing facility. Planned capital
expenditures for 2004 are approximately $3.0 million, including projects for
test fixtures, development system, and computer and office equipment.

On January 21, 2004, our Board of Directors authorized the continuation
of a share repurchase program which expired on December 31, 2003. Under this
extension, we may repurchase a total of one million shares of our common stock
before December 31, 2004. Since the initial repurchase program was instituted in
April 1997, and as of December 31, 2003, the Company has repurchased 461,800
shares of common stock. The repurchased shares are authorized to be utilized
under certain employee benefit programs. At our discretion we will determine the
number of shares and the timing of such purchases, which will be made using
existing cash and short-term investments.

The impact of inflation on both the Company's financial position and
the results of operations has been minimal and is not expected to adversely
affect our 2004 results. Our financial position enables us to meet our cash
requirements for operations and capital expansion programs.

OFF-BALANCE SHEET ARRANGEMENTS

We do not engage in transactions or arrangements with unconsolidated or
other special purpose entities.

RELATED PARTY TRANSACTION

Gregory Quiggle was hired by the Company as Executive Vice President of
Marketing on August 13, 2001. In connection with the recruitment of Mr. Quiggle,
the Company made a loan to Mr. Quiggle in the amount of $210,000 pursuant to a
Promissory Note (the "Note") with interest accruing at 5% per annum. On August
20, 2001, Mr. Quiggle made a payment toward the principal balance of the Note in
the amount of $48,000, thereby reducing the outstanding principal balance of the
Note to $162,000. Beginning in 2003, Mr. Quiggle has made payments of principal
and interest that further reduced the balance of the Note to $160,870 as of
February 6, 2004. The remaining outstanding balance of the Note is due and
payable on or before the earlier of (i) May 2, 2008, (ii) the date of
termination of Mr. Quiggle's employment with the Company, or (iii) the date that
Mr. Quiggle sells or otherwise transfers ownership of all or a portion of 40,200
shares of common stock of Acterna LLC, which shares are being held by the
Company as collateral for payment of the Note. The Note has not been modified
since its issuance.

COMMITMENTS AND CONTRACTUAL OBLIGATIONS

The Company has commitments under various non-cancelable leases related
primarily to real estate in Cheswick, Pennsylvania, Bridgewater, New Jersey and
Sarasota, Florida, which house the Company's operations. Annual rentals due
beyond December 31, 2003 under these agreements are $1.6 million in both 2004
and 2005, $0.9 million in 2006, $0.4 million in 2007 and $0.1 million in 2008.
We are obligated to pay commitment fees under a credit facility as discussed in
the "Liquidity and Capital Resources" section above. We also have commitments to
provide software maintenance services under agreements which are generally one
to three years in length and we have warranty obligations on products sold in
prior periods.

The following table sets forth our aggregate contractual obligations as
of December 31, 2003.

KEY RATIOS

The Company's days sales outstanding in trade accounts receivable was
53 and 57 days at December 31, 2002 and December 31, 2003, respectively. The
Company's inventory turnover ratio was 1.4 and 2.3 turns at December 31, 2002
and December 31, 2003, respectively. Strong buying of MCUs by the RBOCs in the
fourth quarter of 2003, as well as continued targeted programs to reduce
inventories, were the primary reasons for the increasing turns in 2003. Both of
these ratios are determined based on twelve month moving averages.

ACCOUNTING PRONOUNCEMENTS

On August 15, 2001, the Financial Accounting Standards Board (FASB)
issued SFAS No. 143, "Accounting for Asset Retirement Obligations." We adopted
this statement on January 1, 2003 and such adoption did not have a material
effect on our results of operations or financial position.

In June 2002, the FASB issued SFAS No. 146, "Accounting For Costs
Associated With Exit Or Disposal." SFAS No. 146 nullifies Emerging Issues Task
Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (Including Certain
Costs Incurred in a Restructuring)." The new Statement requires that a liability
for a cost associated with an exit or disposal activity be recognized and
measured initially at fair value only when the liability is incurred. SFAS No.
146 is effective for exit or disposal activities that are initiated after
December 31, 2002. The adoption did not have a material effect on the Company's
results of operations or financial position.

In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others" (FIN 45). FIN 45 requires that upon
issuance of a guarantee, a guarantor must recognize a liability for the fair
value of an obligation assumed under a guarantee. FIN 45 also requires
additional disclosures by a guarantor in its interim and annual financial
statements about the obligations associated with guarantees issued. The
recognition provisions of FIN 45 were effective for any guarantees issued or
modified after December 31, 2002. The provisions of FIN 45 did not have a
material impact on the Company's results of operations or financial position.

On January 17, 2003, the FASB issued Interpretation No. 46,
"Consolidation of Variable Interest Entities - an interpretation of ARB No. 51"
(FIN 46). FIN 46 clarifies the application of ARB No. 51, "Consolidated
Financial Statements", to certain entities in which equity investors do not have
the characteristics of a controlling financial interest or do not have
sufficient equity at risk for the entity to finance its activities without
additional subordinated financial support from other parties. Certain provisions
of FIN 46 were effective for the Company after January 31, 2003. Other
provisions are effective at March 31, 2003. The adoption of this standard has
not impacted the Company and the additional provisions are not expected to
impact the Company.

In May 2003, the FASB issued Statement No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity." This
Statement establishes standards for how an issuer classifies and measures
certain financial instruments with characteristics of both liabilities and
equity. It requires that an issuer classify a financial instrument that is
within its scope as a liability (or an asset in some circumstances). This
statement was effective for the Company after May 31, 2003 and did not have a
material impact on our results of operations or financial condition.

The Company early adopted EITF Issue 00-21, "Accounting for Revenue
Arrangements with Multiple Deliverables," which applies to all deliverables
within contractually binding arrangements that include multiple
revenue-generating activities. This issue was finalized in May 2003 and did not
have a material impact on our results of operations or financial condition.

On December 17, 2003, the Staff of the SEC issued SAB 104, "Revenue
Recognition," which supercedes SAB 101, "Revenue Recognition in Financial
Statements." SAB 104 was issued to rescind accounting guidance contained in SAB
101 related to multiple element revenue arrangements, which was superceded as a
result of the issuance of EITF 00-21, "Accounting for Revenue Arrangements with
Multiple Deliverables." This bulletin did not impact our results of operations
or financial condition.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our current investment policy limits our investments in financial
instruments to cash and cash equivalents, individual municipal bonds and
corporate and government bonds. The use of financial derivatives and preferred
and common stocks is strictly prohibited. We believe that our risk is minimized
through proper diversification along with the requirements that the securities
must be of investment grade with an average rating of "A" or better by Standard
& Poor's. We hold our investment securities to maturity and believe that
earnings and cash flows are not materially affected by changes in interest
rates, due to the nature and short-term investment horizon for which these
securities are invested.

TOLLGRADE COMMUNICATIONS, INC. AND SUBSIDIARIES

Statement of Management's Responsibility for Financial
Reporting

The accompanying consolidated financial statements of Tollgrade
Communications, Inc. and Subsidiaries have been prepared by management, who are
responsible for their integrity and objectivity. The statements have been
prepared in conformity with generally accepted accounting principles and include
amounts based on management's best estimates and judgments. Financial
information elsewhere in this Report on Form 10-K is consistent with that in the
financial statements.

Management has established and maintains a system of internal controls
designed to provide reasonable assurance that assets are safeguarded and that
the financial records reflect the authorized transactions of the Company. The
system of internal controls includes widely communicated statements of policies
and business practices that are designed to require all employees to maintain
high ethical standards in the conduct of Company affairs. The internal controls
are augmented by organizational arrangements that provide for appropriate
delegation of authority and division of responsibility.

The financial statements have been audited by PricewaterhouseCoopers
LLP, Independent Auditors. As part of their audit of the Company's 2003
financial statements, PricewaterhouseCoopers LLP considered the Company's
statement of internal controls to the extent they deemed necessary to determine
the nature, timing and extent of their audit tests. The Report of Independent
Auditors follows.

The Board of Directors pursues its responsibility for the Company's
financial reporting through its Audit Committee, which is composed entirely of
outside directors. The Audit Committee has met periodically with the Independent
Auditors and management. The Independent Auditors had direct access to the Audit
Committee, with and without the presence of management representatives, to
discuss the results of their audit work and their comments on the adequacy of
internal accounting controls and the quality of financial reporting.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of Tollgrade Communications, Inc. and
Subsidiaries:

In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, changes in shareholders' equity
and cash flows present fairly, in all material respects, the financial position
of Tollgrade Communications, Inc. and its subsidiaries at December 31, 2003 and
December 31, 2002, and the results of their operations and their cash flows for
each of the three years then ended in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 2 to the consolidated financial statements, the
Company changed its method of accounting for long-lived impairments, goodwill
and other intangible assets in 2002.

TOLLGRADE COMMUNICATIONS, INC. AND SUBSIDIARIES NOTES
TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION, BUSINESS AND BASIS OF PRESENTATION

Tollgrade Communications, Inc. (the "Company") designs, engineers, markets and
supports test system, test access and status monitoring products and test
software for the telecommunications and cable television industries. The
Company's telecommunications proprietary test access products enable telephone
companies to use their existing line test systems to remotely diagnose problems
in Plain Old Telephone Service ("POTS") lines containing both copper and fiber
optics. The Company's test system products, specifically the DigiTest test
platform, focus on helping local exchange carriers conduct the full range of
fault diagnosis along with the ability to prequalify, deploy and maintain
next-generation services including Digital Subscriber Line service. The
Company's cable products consist of a complete cable status monitoring system
that provides a comprehensive testing solution for the Broadband Hybrid Fiber
Coax distribution system. The status monitoring system consists of a host for
user interface, control and configuration; a headend controller for managing
network communications; and transponders that are strategically located within
the cable network to gather status reports from power supplies, line amplifiers
and fiber-optic nodes. The Company was organized in 1986 and began operations in
1988.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles in the United States of America requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of income and expense during
the reporting period. Actual results could differ from those estimates.

PRINCIPLES OF CONSOLIDATION

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

CASH AND CASH EQUIVALENTS

The Company considers highly liquid investments with a maturity of three months
or less when purchased to be cash equivalents. Substantially all of the
Company's cash and cash equivalents are maintained at one financial institution.
No collateral or security is provided on these deposits, other than $100,000 of
deposits per financial institution which is insured by the Federal Deposit
Insurance Corporation.

INVESTMENTS

Short-term investments at December 31, 2003 and December 31, 2002 consisted of
individual municipal bonds stated at cost, which approximated market value.
These securities have maturities of one year or less at date of purchase and/or
contain a callable provision in which the bonds can be called within one year
from date of purchase. The primary investment purpose is to provide a reserve
for future business purposes, including acquisitions and capital expenditures.
Realized gains and losses are computed using the specific identification method.

The Company classifies its investment in all debt securities as "held
to maturity" as the Company has the positive intent and ability to hold the
securities to maturity.

INVENTORIES

Inventories are stated at the lower of cost or market, with cost determined on
the first-in, first-out method. The Company provides appropriate reserves for
any inventory deemed slow moving or obsolete.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost and depreciated on a straight-line
method over the estimated useful lives. Leasehold improvements are amortized
over the related lease period or the estimated useful life, whichever is
shorter.

The cost of renewals and betterments that extend the lives or
productive capacities of properties is capitalized. Expenditures for normal
repairs and maintenance are charged to operations as incurred. The cost of
property and equipment retired or otherwise disposed of and the related
accumulated depreciation or amortization are removed from the accounts, and any
resulting gain or loss is reflected in current operations.

RECEIVABLE FROM OFFICER

The Company extended a loan for $210,000 under a promissory note to an officer
of the Company in July 2001. The note provides for interest at 5% per annum with
repayment under various conditions but no later than May 20, 2008. The loan was
originally secured by collateral which currently has no value. The balance of
the loan at December 31, 2003 and 2002 was $160,940 and $162,000, respectively.
The principal and interest were current at December 31, 2003 and December 31,
2002.

-33-


PRODUCT WARRANTY

The Company records estimated warranty costs on the accrual basis of accounting.
These reserves are based on applying historical returns to the current level of
product shipments and the cost experience associated therewith. In the case of
software, the reserves are based on the expected cost of providing services
within the agreed-upon warranty period. Activity in the warranty accrual is as
follows:



2002 2003
----------- -----------

Balance at the beginning of the year $ 2,068,000 $ 1,981,000
Accruals for warranties issued during the year 645,920 872,000
Accruals related to pre-existing warranties (106,029) (182,000)
Cheetah opening accrual - See Note 2 ---- 225,000
Settlements during the year (626,891) (746,000)
----------- -----------
Balance at the end of the year $ 1,981,000 $ 2,150,000
=========== ===========


REVENUE RECOGNITION

Revenue from product sales is recognized at the time of shipment (FOB shipping
terms) when risk of loss, ownership and title have transferred to the customer,
which coincides with shipment of related products, and collection is reasonably
assured. Software license revenue is recognized in accordance with the Emerging
Issues Task Force Issue 00-21, "Accounting for Revenue Arrangements with
Multiple Deliverables." The Company also follows Staff Accounting Bulletin
("SAB") 104, "Revenue Recognition" issued by the staff of the Securities
Exchange Commission which provides guidance related to revenue recognition.
Revenue from software license, which is comprised of fees for perpetual licenses
derived from contracts with corporate customers, is recognized when persuasive
evidence of an arrangement exists, the product is delivered, written acceptance
is received from the customer which states that no significant Company
obligations remain, the fee is fixed or determinable, and collectibility is
probable. In cases for orders of custom software, or orders that require
significant software customization, the Company will employ contract accounting
using the percentage-of-completion method whereby revenue is recognized based on
costs incurred to date compared to total estimated contract cost. Revenue from
Services (testability consulting) is recognized upon services being rendered.
Reimbursement for out-of-pocket costs is recognized as revenue and
simultaneously recognized as the cost of product sales. Revenue from Services
also includes revenue from maintenance agreements. Maintenance revenue is
generally recognized on a straight-line basis over the life of the related
agreement, which is typically one year. Customer advances and amounts due from
customers in excess of revenue recognized are recorded as deferred income.
Revenue for license and royalty fees is recognized when earned.

IMPAIRMENT OF LONG-LIVED ASSETS

Long-lived and intangible assets to be held and used are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of
such assets may not be recoverable. Intangible assets are reviewed at least
annually. Determination of recoverability is based on an estimate of discounted
or undiscounted future cash flows resulting from the use of the asset and its
eventual disposition. Measurement of an impairment loss for long-lived assets
and certain identifiable intangible assets that management expects to hold and
use is based on the fair value of the assets. No impairments have been recorded
to date.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs to develop or improve hardware-related products
are charged to operations as incurred.

CAPITALIZED SOFTWARE DEVELOPMENT COSTS

Any costs incurred to establish the technological feasibility of software to be
sold or otherwise marketed are expensed as research and development costs. Costs
incurred subsequent to the establishment of technological feasibility, and prior
to the general availability of the product to the public are capitalized and
subsequently amortized under the straight-line method. The Company defines
technological feasibility as coding and testing in accordance with detailed
program designs. Internally generated software development costs that have been
capitalized were $115,383 in 2003, $68,100 in 2002 and none in 2001. Such costs
are being amortized over five years.

INCOME TAXES

The Company follows the provisions of SFAS No. 109, "Accounting for Income
Taxes. Under SFAS No. 109, deferred tax liabilities and assets are determined
based on the "temporary differences" between the financial statement carrying
amounts and the tax basis of assets and liabilities using enacted tax rates in
effect in the years in which the differences are expected to reverse. Valuation
allowances are established when necessary to reduce deferred tax assets to the
amount expected to be realized.

SEGMENT INFORMATION

The Company follows the provisions of SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information, Financial Reporting for Segments of a
Business." This statement establishes standards for reporting information about
operating segments, products and services, geographic areas and major customers
in annual and interim financial statements. The Company manages and operates its
business as one segment. International sales were 5.8% of revenues in 2003, 6.3%
in 2002 and 5.3% in 2001.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities," as amended
by SFAS No. 138, "Accounting for Certain Instruments and Certain Hedging
Activities," and SFAS No, 149, "Amendment of Statement 133 on Derivative
Instruments and Hedging." This statement establishes standards for reporting
information about various derivative financial instruments and accounting for
their change in fair value. The Company does not hold or issue derivative
instruments for hedging purposes and, therefore, this standard does not have a
material effect on the consolidated financial position or results of operations
of the Company.

RECLASSIFICATIONS

Certain reclassifications have been made to prior year amounts to conform with
the current year presentation. These reclassifications had no effect on reported
net income.

ACCOUNTING FOR STOCK-BASED COMPENSATION

The Company has two stock-based employee compensation plans which are described
more fully in Note 5. The Company accounts for these plans under the recognition
and measurement provisions of Accounting Research Bulletin ("APB") Opinion No.
25, "Accounting for Stock Issued to Employees." Under these provisions,
stock-based employee compensation cost is not reflected in net income for any
year, as all options granted under the plans had an exercise price equal to the
market value of the underlying common stock on the date of grant. If the Company
had elected to recognize compensation cost for these stock options based on the
fair value method set forth in SFAS No. 123, "Accounting for Stock-Based
Compensation," net income and earnings per share would have reflected the pro
forma amounts indicated in the following table:

2. ACQUISITIONS

On September 30, 2001, the Company acquired certain assets and assumed certain
liabilities of the LoopCare(TM) product line from Lucent Technologies, Inc. for
approximately $62,029,000 in cash, which includes approximately $2,200,000 of
acquisition-related costs. The assets consisted principally of rights to
existing contracts, software and related computer equipment, while the
liabilities were principally related to software warranties currently under
contract and deferred income. The Company used available cash and short-term
investments to finance the acquisition. The LoopCare acquisition was recorded
under the purchase method of accounting and, accordingly, the results of
operations of the LoopCare business since October 1, 2001 have been included in
the consolidated financial statements.

On February 13, 2003, the Company acquired certain assets and assumed
certain liabilities of the Cheetah(TM) status and performance monitoring product
line ("Cheetah") from Acterna, LLC ("Acterna") for approximately $14,300,000 in
cash. In addition, acquisition-related costs of approximately $599,000 were
capitalized for a total cost of approximately $14,899,000. The transaction
provided for an earnout to be paid in the first half of 2004 of up to $2,400,000
based on certain 2003 performance targets. The current calculation indicates
that amounts due under this provision are immaterial. The acquired assets
consist principally of existing sales order backlog, product inventory,
intellectual property, software and related computer equipment, while the
assumed liabilities principally relate to deferred software maintenance,
warranty and other obligations. The $14,300,000 due at closing and related
acquisition expenses were paid from available cash and short-term investments.
The Company believes that the acquired product line complements its current
cable operations and positions the Company as a leading supplier of testing
equipment and software for the cable industry. The acquisition was recorded
under the purchase method of accounting in accordance with the provisions of
SFAS No. 141, "Business Combinations" and SFAS No. 142, "Goodwill and Other
Intangible Assets," and accordingly, the results of operations of the acquired
product line from February 14, 2003 forward are included in the consolidated
financial statements of the Company.

The Company has made an allocation of the Cheetah purchase price to the
fair value of assets acquired and liabilities assumed. The purchase price
remains subject to change pending agreement between the parties regarding the
earn-out provision and post closing purchase price adjustments. Any changes to
the purchase price are expected to be accounted for as adjustments to goodwill
and may be material.

=================================================================


An independent valuation consultant assisted management in its initial
determination of fair value assigned to certain intangible assets other than
goodwill. Discounted future cash flow models were utilized where appropriate.

The Cheetah product line has maintained a significant market share in
cable status and performance monitoring equipment for more than 25 years and has
a large installed customer base, including many of the largest multiple system
cable operators. The Company has assumed that, on average, approximately 85% of
future revenues attributable to Cheetah products will be derived from this
customer base and, based on prior experience, does not anticipate turnover or
loss of these customers. Therefore, the Company has concluded that the customer
base and Cheetah trademark intangible assets have an indefinite life.
Consequently, in accordance with SFAS No. 142, "Goodwill and Other Intangible
Assets," the values assigned to customer base and the Cheetah trademark, as well
as to related goodwill, are not being amortized for financial reporting
purposes.

The Company intends that the base software will be used in future
releases of CheetahNet(TM) (formerly NetMentor(TM)) and other software products
with little change into the foreseeable future. Similarly, the proprietary
technology embedded in transponder hardware is designed to have a relatively
long useful life. Therefore, the Company has determined that the base software
and proprietary software have a remaining useful life of ten years and are being
amortized for financial reporting purposes over that period.

The Company obtained a backlog of customer purchase orders totaling
approximately $2,160,000 in connection with the Cheetah acquisition. Using a
discounted cash flow analysis, the Company determined an acquired value of
$543,000 for this backlog. This asset, which is included in prepaid expenses and
other current assets, is being amortized as the related orders are being
realized as sales revenue. Amortization of approximately $540,000 was recognized
in cost of sales from the date of the acquisition through December 31, 2003.

For tax purposes, the Company is amortizing all intangible assets over
15 years. Goodwill deducted for tax purposes amounted to $269,000 in 2001,
$1,077,000 in 2002 and $1,265,000 in 2003.

SFAS No. 142 provides that entities evaluate the remaining useful lives
of intangible assets determined to have indefinite useful lives periodically to
determine whether events and circumstances continue to support an indefinite
useful life and that such assets be tested at least annually for impairment of
value. The Company's policy is to test all intangible assets for impairment in
value as of December 31 of each year or more frequently if events or changes in
circumstances indicate that assets might be impaired.

The Company had net intangible assets, including goodwill, of
$71,556,000 at December 31, 2003, of which $58,620,000 resulted from the
LoopCare acquisition and $12,936,000 resulted from the Cheetah acquisition. The
Company has determined that it has only one operating unit and has completed a
test for goodwill impairment as of December 31, 2003 by comparing the aggregate
market value of the Company's stock with the Company's book carrying value,
including goodwill. This test indicated that there was no impairment of the
goodwill carrying value.

All other intangible assets were tested for impairment of carrying
value as of December 31, 2003 using assumptions and techniques employed in the
original valuations and following the guidance of SFAS No. 144, "Accounting for
the Impairment or Disposal of Long-Lived Assets." Specifically, the sum of the
projected future cash flows to be derived from assets with definite lives was
compared with the net book carrying value. The impairment test for
non-amortizable intangible assets other than goodwill consisted of a comparison
of the estimated fair value with carrying amounts. The values of the LoopCare
trade name and Cheetah trademark were measured using the relief-from-royalty
method and discounted cash flow analyses were employed to test the value of the
LoopCare base software and post warranty maintenance service agreements and the
value of the Cheetah customer base. These tests indicated that none of the
intangible assets had impairment in carrying value. The Company will retest
these assets annually as of December 31 or more frequently if events or changes
in circumstances indicate that assets might be impaired.

Revenues for 2002, cost of sales and operating expenses for proforma
determinations were based on historical information provided by Acterna with
proforma adjustments made to adjust gross margins to 50% of revenues and to
adjust operating expenses based upon the Company's financial plan for Cheetah
for 2003. These adjustments were made to reflect significant changes to
operations made by the Company since the acquisition. This proforma financial
information is presented for comparative purposes only and is not necessarily

On February 19, 1999, the Board of Directors approved a proposal to
increase the number of shares under the 1995 Long-Term Incentive Compensation
Plan (the "1995 Plan") by 230,000 shares, with a corresponding cancellation of a
similar number of shares under the 1998 Employee Incentive Compensation Plan
(the "1998 Plan"). The shareholders approved this action on May 6, 1999. On
December 14, 2000, the Board of Directors of the Company approved a proposal to
increase the number of shares available under the 1998 Plan by 200,000 shares,
from 740,000 to 940,000 shares. On May 23, 2001, the shareholders approved an
amendment to the Company's 1995 Plan, as adopted by the Board of Directors on
January 25, 2001, to increase the number of shares available under the Plan by
275,000 shares, from 2,210,000 to 2,485,000. The aggregate number of shares of
the Company's Common Stock which may be issued under the 1995 Plan and the 1998
Plan is 2,485,000 and 940,000 shares, respectively, subject to proportionate
adjustment in the event of stock splits and similar events. On January 24, 2002,
the Board of Directors approved a proposal to increase the number of shares
available under the 1998 Plan by 50,000 shares, from 940,000 to 990,000 shares.
That same date, the Board also approved a proposal to increase the number of
shares available under the 1995 Plan by 200,000. On May 7, 2002, the
shareholders approved an amendment to the 1995 Plan, as adopted by the Board of
Directors on January 24, 2002, to increase the number of shares available by
200,000 from 2,485,000 to 2,685,000. The maximum number of shares which may be
awarded under the 1995 Plan to any one Named Executive Officer during any
calendar year of the life of the plan is 200,000 shares. All full-time active
employees of the Company, excluding officers and directors, are eligible to
participate in the 1998 Plan. Amendments to the 1998 Plan do not require the
approval of the shareholders, but are approved by the Board of Directors. The
Company has 2,061,767 total shares reserved under the option plans. The shares
authorized but not granted under these plans at December 31, 2002 and 2003 were
as follows:

The fair value of the stock options used to compute pro forma net income and
earnings per share disclosures is the estimated present value at grant date
using the Black-Scholes option-pricing model with the following weighted average
assumptions for 2001, 2002 and 2003: expected volatility of 87.7% in 2001, 92.3%
in 2002 and 96.7% in 2003; a risk-free interest rate of 3.65% in 2001, 2.67% in
2002 and 2.44% in 2003; and an expected holding period of four years. Using the
Black-Scholes option-pricing model, the weighted average fair value of stock
options granted during 2001, 2002 and 2003, is $17.84, $9.52 and $9.61 per
share, respectively.

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK PURCHASE RIGHTS

In order to protect shareholder value in the event of an unsolicited offer to
acquire the Company, on July 23, 1996, the Board of Directors of the Company
declared a dividend of one preferred stock purchase right for each outstanding
share of the Company's common stock. The dividend was payable on August 15, 1996
to shareholders of record as of that date. The aforementioned rights are
exercisable only if a person or group acquires or announces an offer to acquire
20% or more of the Company's common stock. In such an event, each right will
entitle shareholders to buy one-hundredth of a share of a new series of
preferred stock at an exercise price of $115.00. Each one-hundredth of a share
of the new preferred stock has terms designed to make it the economic and voting
equivalent of one share of common stock.

If a person or group acquires 20% or more of the Company's outstanding
common stock, each right not owned by the person or group will entitle its
holder to purchase at the right's exercise price a number of shares of the
Company's common stock (or, at the option of the Company, the new preferred
stock) having a market value of twice the exercise price. Further, at any time
after a person or group acquires 20% or more (but less than 50%) of the
outstanding common stock, the Board of Directors may at its option, exchange
part or all of the rights (other than rights held by the acquiring person or
group) for shares of the Company's common or preferred stock on a one-for-one
basis. Each right further provides that if the Company is acquired in a merger
or other business transaction, each right will entitle its holder to purchase,
at the right's exercise price, a number of the acquiring company's common shares
having a market value at that time of twice the exercise price.

The Board of Directors is entitled to redeem the rights for one cent
per right at any time before a 20% position has been acquired. The Board of
Directors is also authorized to reduce the 20% thresholds referred to above to
not less than 10%.

6. LICENSE AND ROYALTY FEES

The Company has entered into several technology license agreements with certain
major Digital Loop Carrier (DLC) vendors and major Operation Support System
(OSS) equipment manufacturers under which the Company has been granted access to
the licensor's patent technology and the right to manufacture and sell the
patent technology in the Company's product line. The Company is obligated to pay
royalty fees, as defined, through the terms of these license agreements. Under
these agreements, license and royalty fees are due only upon purchase of the
technology or shipment of units; there are no contingent payment provisions in
any of these arrangements. Royalty fees of $1,832,981, $889,024 and $966,715
were incurred in 2001, 2002 and 2003, respectively, and are included in cost of
product sales in the accompanying consolidated statements of operations.

limit on deductions each year. Unused carryforward losses will expire in 2020.
The Company has recorded a valuation allowance of $450,000 as of December 31,
2001 in connection with the Pennsylvania carryforward tax benefits.

8. LINE OF CREDIT

Effective December 20, 2001, and amended effective February 7, 2003, the Company
executed a five-year $25,000,000 Unsecured Revolving Credit Facility (the
"Facility") with a bank. In accordance with the terms of the Facility, the
proceeds must be used for general corporate purposes, working capital needs, and
in connection with certain acquisitions, as defined. The Facility contains
certain standard covenants with which the Company must comply, including a
minimum fixed charge ratio, a minimum defined level of tangible net worth and a
restriction on the amount of capital expenditures that can be made on an annual
basis, among others. A maximum leverage ratio restricts total borrowings of the
Company to approximately $18.7 million during the first quarter of 2004.
Interest is payable on any amounts utilized under the Facility at prime, or the
prevailing Euro rate plus 1.0% to 1.5% depending on the fixed charge coverage
ratio, at the option of the Company. Commitment fees are paid quarterly at the
rate of 0.25% per annum on the average unused commitment. At December 31, 2003,
there were no amounts outstanding under the Facility.

9. LEASE COMMITMENTS

The Company leases office space and equipment under agreements which are
accounted for as operating leases. The Cheswick, Pennsylvania office lease
expires December 31, 2005, while the Cheswick equipment leases expire in August
2005. Both office and equipment leases expire in January 2007 for the
Bridgewater, New Jersey facility and April 2008 for the Sarasota, Florida
facility. In addition, all three of the office leases include provisions for
possible adjustments in annual future rental commitments relating to excess
taxes and excess maintenance costs that may occur. The Company is also involved
in various month-to-month leases for research and development equipment.

Minimum annual future rental commitments under noncancelable leases as of
December 31 are:



2004 $ 1,600,812
2005 $ 1,598,012
2006 $ 866,785
2007 $ 438,407
2008 $ 103,750


The rent expense for all lease commitments was $890,943, $1,170,101 and
$1,479,754 in 2001, 2002 and 2003, respectively.

10. MAJOR CUSTOMERS, REVENUE CONCENTRATION AND DEPENDENCE ON CERTAIN SUPPLIERS

The Company designs, engineers, markets and supports test system, test access
and status monitoring products for the telecommunications and cable television
industries. Sales are concentrated primarily with the four Regional Bell
Operating Companies ("RBOCs") as well as major independent telephone and cable
companies and to certain digital loop carrier equipment manufacturers. Sales are
derived primarily from the Company's metallic channel unit (MCU) product line
which accounted for approximately 39% of the Company's net sales for 2003. The
cable television product lines, which include both CheetahLight (formerly
LIGHTHOUSE) and the newly acquired CheetahNet lines, contributed approximately
27% while DigiTest and LoopCare RTU sales accounted for approximately 10% and
5%, respectively, of the Company's net sales for 2003. Revenue from Services,
which includes installation oversight and project management services provided
to RBOCs and fees for LoopCare and Cheetah software maintenance, accounted for
approximately 19% of the Company's net sales for 2003.

Sales to RBOC customers accounted for approximately 71%, 77% and 56% of
the Company's net product sales for fiscal years 2001, 2002 and 2003,
respectively. During 2001, 2002 and 2003, sales to three RBOC customers
individually exceeded 10% of consolidated revenues and, on a combined basis,
comprised 66% (individually, 38%, 14% and 14%), 70% (individually, 38%, 18% and
14%) and 48% (individually, 17%, 17% and 14%) of the Company's net product
sales, respectively. Sales to a large independent carrier accounted for
approximately 11% of the Company's net product sales for fiscal year 2001 and
was less than 10% in 2002 and 2003. Due to the Company's present dependency on
RBOC customers, the loss of one or more of the RBOCs as a customer, or the
reduction of orders for the Company's products by the RBOCs, could materially
and adversely affect the Company.

The Company utilizes three key independent subcontractors to perform a
majority of the circuit board assembly and in-circuit testing work on its
products. The Company also utilizes other subassembly contractors on a more
limited basis. The loss of the subcontractors could cause delays in the
Company's ability to meet production obligations and could have a material
adverse effect on the Company's results of operations. In addition, shortages of
raw material or production capacity constraints at the Company's subcontractors
could negatively affect the Company's ability to meet its production obligations
and result in increased prices for affected parts. Any such reduction may result
in delays in shipments of the Company's products or increases in the price of
components, either of which could have a material adverse impact on the Company.

11. EMPLOYEE BENEFIT PLANS

The Company has a 401(k) benefit plan. Eligible employees, as defined in the
plan, may contribute up to 20% of eligible compensation, not to exceed the
statutory limit. The Company does not make matching contributions to the plan.

12. SEVERANCE AND RELATED EXPENSE

On September 30, 2002, the Company announced its second restructuring program in
two years to implement certain cost reduction initiatives which included the
elimination of 47 positions, primarily in research and development. The
restructuring program resulted in a pre-tax charge for severance, outplacement
and other related costs of $175,723 in 2002. The initial restructuring program
in April 2001 resulted in a pre-tax charge of $291,000 in 2001 and eliminated
approximately 80 positions. All amounts for 2001 and 2002 have been paid.

13. RECENT ACCOUNTING PRONOUNCEMENTS

On August 15, 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligation." On October 4, 2001, FASB issued SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets." The Company
adopted these statements on January 1, 2003 and such adoption did not have a
material effect on the Company's results of operations or financial position.

In June 2002, the FASB issued Statement of Financial Accounting
Standards (SFAS) No. 146, "Accounting for Costs Associated with Exit or
Disposal." SFAS No. 146 nullifies Emerging Issues Task Forces Issue No. 94-3,
"Liability Recognition for Certain Employee Termination Benefits and Other Costs
to Exit an Activity (Including Certain Costs Incurred in a Restructuring)." The
new statement requires that a liability for a cost associated with an exit or
disposal activity be recognized and measured initially at fair value only when
the liability is incurred. SFAS No. 146 is effective for exit or disposal
activities that are initiated after December 31, 2002. The adoption did not have
a material effect on the Company's results of operations or financial position.

In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others" ("FIN 45"). FIN 45 requires that upon
issuance of a guarantee, a guarantor must recognize a liability for the fair
value of an obligation assumed under a guarantee. FIN 45 also requires
additional disclosures by a guarantor in its interim and annual financial
statements about the obligations associated with guarantees issued. The
recognition provisions of FIN 45 were effective for any guarantees that are
issued or modified after December 31, 2002. The provisions of FIN 45 did not
have a material impact on the Company's results of operations or financial
position.

The Company early adopted EITF Issue 00-21, "Accounting for Revenue
Arrangements with Multiple Deliverables," which applies to all deliverables
within contractually binding arrangements that include multiple
revenue-generating activities. This Issue was finalized in May 2003 and did not
have a material impact on the Company's results of operations or financial
condition.

On December 17, 2003, the Staff of the SEC issued SAB 104, "Revenue
Recognition," which supercedes SAB 101, "Revenue Recognition in Financial
Statements." SAB 104 was issued to rescind accounting guidance contained in SAB
101 related to multiple element revenue arrangements, which was superceded as a
result of the issuance of EITF 00-21, "Accounting for Revenue Arrangements with
Multiple Deliverables." This bulletin did not impact our results of operations
or financial condition.

15. PER SHARE INFORMATION

Net income per share has been computed in accordance with the provisions of SFAS
No. 128, "Earnings Per Share" for all periods presented. On February 10, 2000,
the Company's Board of Directors authorized a two-for-one stock split of the
Company's common stock, payable in the form of a 100 percent stock dividend. On
March 20, 2000, shareholders of record received one additional share of common
stock for each share of common stock held of record on February 28, 2000. All
share and per share information reflects the two-for-one split of the Company's
common stock. SFAS No. 128 requires companies with complex capital structures to
report earnings per share on a basic and diluted basis, as defined. Basic
earnings per share are calculated on the actual number of weighted average
common shares outstanding for the period, while diluted earnings per share must
include the effect of any dilutive securities. All prior periods have been
restated in accordance with SFAS No. 128.

A reconciliation of earnings per share is as follows:

(1) 1998 Employee Incentive Compensation Plan. The Company's 1998 Employee
Incentive Compensation Plan (the "Plan"), which was adopted by the Company's
Board of Directors and is effective as of January 28, 1998, is intended, among
other purposes, to help the Company to motivate, attract and retain qualified
employees (other than officers and directors of the Company). The Plan is
administered by the Compensation Committee of the Company's Board of Directors
(the "Committee"), which has full discretion to determine the employees who
receive awards under the Plan as well as the nature and size of such awards. The
Committee may issue nonqualified stock options, stock appreciation rights,
restricted stock, performance shares and performance units under the Plan. Award
recipients (other than recipients of stock appreciation rights) are subject to a
non-competition arrangement with the Company. Upon a change of control in the
Company, all awards become exercisable, vested or fully earned, as applicable.
The exercise price of options and the sale price of restricted stock granted
under the Plan is 100% of the fair market value of the Company's common stock as
of the date of grant. All options granted under the plan expire not later than
ten years after the date of grant and typically vest over two years. There are
currently 990,000 shares of the Company's common stock authorized under the Plan
for granting awards.

See Note 5 to the consolidated financial statements on pages -- through -- of
this Annual Report on Form 10-K to Shareholders for additional information
regarding the Company's equity compensation plans.
