             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.       BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements included
herein have been prepared by Tollgrade Communications, Inc. (the "Company") in
accordance with accounting principles generally accepted in the United States of
America for interim financial information and Article 10 of Regulation S-X. The
condensed consolidated financial statements as of and for the three-month and
six-month periods ended June 29, 2002 should be read in conjunction with the
Company's consolidated financial statements (and notes thereto) included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2001.
Accordingly, the accompanying condensed consolidated financial statements do not
include all of the information and footnotes required by accounting principles
generally accepted in the United States of America for complete financial
statements, although the Company believes that the disclosures are adequate to
make the information presented not misleading. In the opinion of Company
management, all adjustments considered necessary for a fair presentation of the
accompanying condensed consolidated financial statements have been included, and
all adjustments are of a normal and recurring nature. Operating results for the
three-month and six-month periods ended June 29, 2002 are not necessarily
indicative of the results that may be expected for the year ending December 31,
2002.

2.       ACQUISITION AND INTANGIBLE ASSETS

On September 30, 2001, the Company acquired certain assets and assumed certain
liabilities of the LoopCare(TM) Product line from Lucent Technologies, Inc.
("Lucent") for approximately $62,029,000 in cash which includes approximately
$2,200,000 of acquisition-related costs. The acquisition has been recorded under
the purchase method of accounting and, accordingly, the results of operations of
the LoopCare product line since October 1, 2001 have been included in the
consolidated financial statements.

The Company has 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. In connection with the acquisition,
$45,800,000 of intangible assets were identified, of which $7,300,000 were
related to capitalized software and determined to have a definite life, while
the remaining $38,500,000 of the identified intangible assets, as well as
goodwill of approximately $16,162,000, are not being amortized as they have been
determined to have an indefinite useful life.

As of January 1, 2002, the Company fully adopted the provisions of SFAS No. 142.
SFAS 142 requires that goodwill be analyzed for impairment under a two-step
process. The first step of the goodwill impairment test is to identify potential
impairment by comparing the fair value of the reporting unit with its carrying
amount, including goodwill. The second step, used to measure the potential
impairment loss of the goodwill, is to compare the implied fair value of the
reporting unit goodwill with the carrying amount of that goodwill. The Company
has determined that it has only one reporting segment and has completed the
first step of the goodwill impairment test as of June 29, 2002 by comparing the
aggregate market value of the Company's

                                      7
<PAGE>
stock with its carrying value, including goodwill. This test indicated that
there was no impairment of goodwill carrying value and, accordingly, step two
of the test was not required. Future changes in circumstances, including a
sustained decline in the aggregate market value of the Company's stock, could
necessitate a reconsideration of whether an impairment of goodwill carrying
value has occurred.

Developed product software costs are being amortized over a five-year useful
life. An annual review for impairment of these assets will be made following the
guidance of paragraphs 4-11 of SFAS 121. Specifically, the sum of the
undiscounted future cash flows expected to be derived from the developed product
software will be compared with the carrying value. If the carrying value is
greater than the sum of the projected cash flows, an impairment loss will be
recorded equal to the excess of the carrying value over the fair value of the
assets. The fair value will be determined by a separate test utilizing the
discounted present value of the expected cash flow stream from the software.

In addition, other intangible assets that are not subject to amortization will
be tested for impairment annually or more frequently if events or changes in
circumstances indicate that the asset might be impaired. The impairment test for
non-amortizable intangible assets will consist of a comparison of the fair value
of an intangible asset with its carrying amount. The Company intends to test the
value of intangible assets other than goodwill as of December 31, 2002 using the
same testing methodology employed by independent consultants in making the
initial valuation in 2001. Specifically, the relief-from-royalty method will be
used to test the value of the LoopCare trade name and discounted cash flow
analyses will be used to value the base software and post warranty maintenance
service agreements.

One of the Company's four RBOC customers has recently notified the Company of
its intention to negotiate a need based, time and materials fee instead of the
fixed maintenance fee when its current service agreement expires on December 31,
2002. The Company has agreed to negotiate in good faith towards this type of
arrangement but fully intends to maintain the value of this contract. Therefore,
at this point, the Company believes the value and non-amortizing characteristics
of this intangible asset to be preserved. However, if through negotiations, a
new maintenance agreement with the RBOC customer cannot be reached, or if a new
agreement is reached that is believed will result in less revenue to the Company
than the current fixed fee agreement, the current fair value of the maintenance
service agreements may be determined to be less than the $32,000,000 carrying
value, perhaps materially so, resulting in a charge against operating income for
2002 and/or commencement of amortization of the remaining fair value over its
determined useful life. A similar analysis of the fair value of the maintenance
service agreements could be required if any of the Company's RBOC customers
reduce or terminate their maintenance service agreements due to the RBOC
customers' own financial difficulties.

The proforma results of operations for the quarter and six-months ended June 30,
2001 reflected above include one-fourth and one-half, respectively, of the
annual audited results of the LoopCare product line business for 2001. Proforma
adjustments made include an estimated allocation of selling, general and
administrative expenses to the LoopCare operations based upon budgeted costs for
2002 and proforma amortization of the developed product software over five
years. Proforma adjustments were also made to take into account the cost of
money in connection with the acquisition costs. This was estimated by reducing
interest income at historical earning rates for working capital deemed to have
been available to apply to the acquisition costs and estimating interest expense
on borrowed funds for residual acquisition costs at the historical prime rates
of interest plus 1.5%. Adjustments were also made to reflect the tax
consequences of the foregoing proforma adjustments.

The following information is provided regarding the Company's intangible assets:

4.       SHORT-TERM AND LONG-TERM INVESTMENTS

Short-term investments at June 29, 2002 and December 31, 2001 consisted of
individual municipal bonds stated at cost, which approximated market value.
These securities have a maturity 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. Long-term investments are comprised of individual
municipal bonds with a maturity of more than one year but less than eighteen
months and are stated at cost, which approximated market value. 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 which is in accordance with Statement of Financial
Accounting Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt
and Equity Securities."

The estimated fair values of the Company's financial instruments are as follows:

5.       INCOME PER COMMON SHARE

Net income per share is calculated by dividing net income by the weighted
average number of common shares plus incremental common stock equivalent shares
(shares issuable upon exercise of stock options). Incremental common stock
equivalent shares are calculated for each measurement period based on the
treasury stock method, which uses the monthly average market price per share.

The calculation of net income per common and common equivalent shares follows

6.       DEFERRED AND REFUNDABLE TAX ASSETS

The Company's current refundable tax assets as of December 31, 2001 included a
tax benefit of $1,396,736 resulting from the exercising of nonqualified stock
options under the Company's stock option programs during 2001. The Company is
entitled to a tax deduction equal to the difference between the fair market
value of the shares received by the option holders upon exercise and the
exercise price of the nonqualified stock options. The Company received
$8,417,270 in 2001 in federal and state refunds in taxes paid in prior years.
During the first quarter of 2002, the Company received $900,000 in federal
income tax refunds associated with prior year taxes paid. It is anticipated that
the remaining current refundable tax assets will be substantially utilized in
2002 either through refunds of prior year taxes paid or the elimination of
income taxes due.

7.       STOCK REPURCHASE PROGRAM

On April 19, 2001, the Company announced its Board of Directors authorized the

shares of common stock. The Company was authorized to repurchase a total of one
million shares of its common stock. Through December 31, 2001, no additional
shares were repurchased under this extended program.

On January 24, 2002, the Board of Directors authorized the continuation of the
share repurchase program under which the Company may repurchase a total of one
million shares of its common stock before December 31, 2002. During the quarter
ended March 30, 2002, the Company purchased an additional 75,000 shares of the
Company's common stock under this program. No additional shares were repurchased

                   REVIEW REPORT OF INDEPENDENT ACCOUNTANTS

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

We have reviewed the accompanying condensed consolidated balance sheet of
Tollgrade Communications, Inc. and its subsidiaries as of June 29, 2002 and the
related condensed consolidated statements of operations for each of the
three-month and six-month periods ended June 29, 2002 and June 30, 2001 and the
condensed consolidated statement of cash flows for the six-month periods ended
June 29, 2002 and June 30, 2001 and the statements of changes in shareholders
equity for the six-month period ended June 29, 2002. These financial statements
are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying condensed consolidated interim financial statements
for them to be in conformity with accounting principles generally accepted in
the United States of America.

We previously audited in accordance with auditing standards generally accepted
in the United States of America, the consolidated balance sheet as of December
31, 2001, and the related consolidated statements of operations, shareholders'
equity and of cash flows for the year then ended (not presented herein), and in
our report dated January 21, 2002 we expressed an unqualified opinion on those
consolidated financial statements. In our opinion, the information set forth in
the accompanying condensed consolidated balance sheet as of December 31, 2001,
is fairly stated in all material respects in relation to the consolidated
balance sheet from which it has been derived.

Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
          FINANCIAL CONDITION

The following discussion should be read in conjunction with the Condensed
Consolidated Financial Statements and Notes thereto appearing elsewhere in this
report.

CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995.

This Quarterly Report on Form 10-Q contains statements relating to future events
that are considered "forward-looking statements." These statements, which may be
expressed in a variety of ways, including the use of future or present tense
language, relate to, among other things, projected cash flows used in the
valuation of intangible assets, the anticipated results of negotiations for new
maintenance service agreements, as well as purchase orders and other customer
purchase agreements, the ability to utilize current deferred and refundable tax
assets, opportunities which the Company's professional services offer to
customers, the potential loss of certain customers, the timing of orders from
customers, the effect of consolidations in the markets to which the Company
sells, the effects of the economic slowdown in the telecommunications industry,
the possibility of future provisions for slow moving inventory, and the effect
on earnings and cash flows of changes in interest rates.

These forward-looking statements, and other forward-looking statements
contained in other public disclosures of the Company which make reference to
the cautionary factors contained in this Report, are based on assumptions that
involve risks and uncertainties and are subject to change based on the
considerations described below. The Company does not undertake any obligation
to publicly update any forward-looking statements.

General economic conditions and the economic conditions of the
telecommunications industry, including the effect of negative line growth and
competition for the Company's RBOC customers from wireless, cable providers and
other carriers entering the local telephone service market can affect the
capital budgets of the Company's customers. If such conditions result in a
reduction of such budgets, the Company's revenues can be adversely affected.
If the Company's customers find themselves unable to meet their established
purchase forecasts and their own growth projections, such customers may curtail
their purchase of the Company's products, which would adversely affect the
Company's revenues.

If the financial strength of certain of the Company's major customers should
deteriorate or such customers encounter difficulties in accessing capital, the
ability of such customers to purchase and pay for the Company's products could
be impaired, with a corresponding adverse affect on the Company's revenues.
If third parties with whom the Company has entered into sales and marketing
partnerships should fail to meet their own performance objectives or (in some
cases) prove unable to continue to provide vendor financing to certain local
exchange carriers, customer demand for the Company's products could be adversely
affected, which would have an adverse effect on the Company's revenues.
Seasonal fluctuations in customer demand for the Company's products can create
corresponding fluctuations in period to period revenues, and any increases in
the rate of order cancellation by customers could adversely affect future
revenues.

The carrying value of certain intangible assets, including goodwill, acquired
by the Company from Lucent Technologies, Inc. ("Lucent") could be impaired if
changing market conditions indicate that lower than anticipated cash flows will
be produced by such intangible assets.

                                      15

If the Company were to encounter a shortage of key manufacturing components from
limited sources of supply, or experience manufacturing delays caused by reduced
manufacturing capacity, loss of key assembly subcontractors or other factors,
the Company's ability to produce and ship its manufactured products could be
adversely affected, with an adverse effect upon revenues.

The introduction of improved products or services or reduced prices by the
Company's competitors could reduce the demand for the Company's products and
services and adversely affect revenues.

If the Company proves unable to respond effectively to technological change in
its industry, such as an evolution of the telephone network from circuit to
packet-based, by developing new products and services and obtaining customer
approval and acceptance of its products and services, demand for the Company's
products and services could be adversely affected, which would adversely affect
revenues.

The Company is dependent on a relatively narrow range of products and a small
number of large customers. As a result, the failure of one or a small number of
the Company's products to gain or maintain acceptance in the marketplace, or the
decision by one or a few of the Company's customers to curtail their purchases
of the Company's products could have an adverse effect on revenues.

If one or more of a small number of key employees of the Company were to cease
to be associated with the Company, the Company's future results could be
adversely affected.

If the Company is unable to successfully assert and defend its proprietary
rights in the technology utilized in its products, its future results could be
adversely affected. If third parties were able to successfully assert that the
Company's use of technology infringed upon the proprietary rights of others, the
future results of the Company could be adversely affected.

If one or more of the Company's products were to prove defective, the Company's
relationships with its customers could be jeopardized and the Company could be
subject to potential liability, adversely affecting the Company's future
results.

If for any reason demand for the Company's products should decrease
substantially, the Company could find itself with excess inventory and
obsolescent parts on hand, which could adversely affect future results.

Changes in government regulation, such as modification or repeal of The
Telecommunications Act of 1996, increasing the costs of doing business by the
Company or its customers, or preventing the Company or its customers from
engaging in business activities they may wish to conduct could adversely affect
the Company's future results.

Overview

The Company was organized in 1986 and began operations in 1988. The Company
designs, engineers, markets and supports test system, test access and status
monitoring products for the telecommunications and cable television industries.
Effective September 30, 2001, the Company purchased certain assets of the
LoopCare(TM) product business from Lucent. These assets consisted of LoopCare
software base code and developed enhancements, as well as the rights to existing
maintenance contracts for the LoopCare software. Effective September 30, 2001,
revenues from the sales of either software base code or developed enhancements
are either reported separately or as part of the Company's revenues attributable
to test system products to which they synergistically relate, while the revenues
from maintenance contracts are reflected as part of the Company's Professional
Services revenues.

The Company has determined that its business has one reportable segment in 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. While the Company does internally develop sales
results associated with the various product categories, this information is not

                                      16
<PAGE>
considered sufficient for segment reporting purposes nor does the chief
operating decision maker make critical decisions or allocate assets based solely
on this information. Its products and services have similar economic
characteristics, the same or similar production processes and are sold to
similar types or classes of customers in, or entering into, the
telecommunications business through similar distribution means. The LoopCare
software product line business was acquired by the Company to broaden its
DigiTest(R) test platform into a system level offering and as a competitive
defense to protect the Company's MCU(R) and DigiTest products' market share.

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 MCU product line, which includes POTS line
testing as well as alarm-related products, represented approximately 52% of the
Company's revenue for the second quarter ended June 29, 2002. The Company's MCU
product line will continue to account for a substantial portion of the Company's
revenues for the foreseeable future.

The Company's DigiTest centralized network test system platform, which includes
certain LoopCare software base code and developed enhancements, focuses on
helping local exchange carriers conduct the full range of fault diagnosis, along
with the ability to qualify, deploy and maintain next generation services that
include Digital Subscriber Line ("DSL") service and Integrated Services Digital
Network ("ISDN") service. The Company's DigiTest system is designed to provide
the complete solution for testing POTS and performing local loop
prequalification for DSL services. The system currently consists of the
comprehensive LoopCare diagnostic software, as well as three integrated pieces
of hardware, the Digital Measurement Node ("DMN"), the Digital Measurement Unit
("DMU"), and the Digital Wideband Unit ("DWU"). When used in an integrated
fashion, the DigiTest system permits local exchange carriers to perform a
complete array of central office testing including POTS, DSL line
prequalification, bridged tap detection, data rate prediction, and in-service
wideband testing. Sales of the DigiTest product line, accounted for
approximately 7% of the Company's revenue for the second quarter of 2002.

The Company's Digital Access Unit ("DAU") provides automated test access of
locally non-switched, two wire circuits and it helps facilitate the line sharing
or the spectral unbundling process for both incumbent (ILEC) and competitive
local exchange carriers (CLECs). Sales of this product line represented less
than 1% of total revenue for the current quarter.

The Company's LoopCare software products consist primarily of engineered
enhancements to the LoopCare base code software, which result in increased
connectivity and versatility of LoopCare within the customers' existing quality
assurance systems. Sales of stand-alone LoopCare software accounted for
approximately 16% of total second quarter 2002 revenue.

The Company's LIGHTHOUSE(R) cable products consist of a complete cable status
monitoring system that provides a broad testing solution for the Broadband
Hybrid Fiber Coax distribution system. The status monitoring system includes a
host for user interface, control and configuration; a head-end 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. Sales of the LIGHTHOUSE product line accounted
for approximately 7% of the Company's revenue for the second quarter of 2002.

                                      17
<PAGE>
The cornerstone of the Company's professional services offering is the
Testability Improvement Initiatives. These services may offer the customer the
opportunity to make improvements in testability levels, while training their own
staffs in targeted geographic regions over a defined period of time. In this
way, the customers' internal repair technicians can make use of automated
systems to diagnose and repair subscriber loop problems, thereby automatically
eliminating the need for the involvement of several highly trained people to do
so. The services business was considerably expanded upon the acquisition of
software maintenance contracts related to the LoopCare software product line.
Including these software maintenance revenues, services revenue accounted for
approximately 18% of the Company's revenue for the second quarter ended June 29,
2002.

The Company's telecommunication product sales and services are primarily to the
four Regional Bell Operating Companies ("RBOCs") as well as major independent
telephone companies and to certain digital loop carrier ("DLC") equipment
manufacturers. For the second quarter ended June 29, 2002, approximately 73% of
the Company's total revenue was generated from sales to these four RBOCs. During
the second quarter of 2002, sales to three RBOCs (SBC, Verizon and BellSouth)
individually exceeded 10% of consolidated revenues and on a combined basis,
comprised approximately 64% (32.8%, 17.7% and 13.7%, respectively) of the
Company's net sales. Although not a 10% customer in the current quarter, in past
periods Qwest has been a 10% customer. Receivables outstanding with Qwest at
June 29, 2002 were $858,473, which includes software maintenance revenue. On an
annual basis, the software maintenance contract is a significant piece of the
Company's LoopCare software maintenance revenue. Based on Qwest's recent public
disclosure, they have indicated they will be restating financial results for the
past three years and they have withdrawn any financial guidance given for 2002.
Due to the Company's present dependency on these key customers including Qwest,
the potential loss of one or more of them as a customer or the reduction of
orders for the Company's products by them could materially and adversely affect
the Company.

The Company's operating results have fluctuated and may continue to fluctuate as
a result of various factors, including the timing of orders from, shipments to,
and acceptance of software by the RBOCs and significant independent telephone
companies. This timing is particularly sensitive to various business factors
within each of the RBOCs, including the RBOCs relationships with their various
organized labor groups, as well as an increasing tendency for the RBOCs to place
large orders for shipment of hardware and software toward the end of the
quarter. In addition, the markets for the Company's products, specifically,
LoopCare, DigiTest and LIGHTHOUSE, 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.

The Company believes that recent changes within the telecommunication
marketplace, including industry consolidation, as well as the Company's ability
to successfully penetrate certain new markets, have resulted in some discounting
and more favorable terms granted to certain customers of the Company. In
addition, certain customers have consolidated product purchases that have
translated into large bulk orders. As stated earlier, there is an increasing
trend, in response to some of these discounting programs, for these customers to
place large bulk orders toward the end of the quarter for shipment of large
quantities of hardware and software in the last month of the quarter. Although
the Company will continue to strive to meet the demands of its customers, which
include delivery of quality products at an acceptable price and on acceptable
terms, there are no assurances that the Company will be successful in
negotiating acceptable terms and conditions in its purchase orders or its
customer purchase agreements. Additionally, continuing consolidation efforts
among the RBOCs, and their ability

                                      18
<PAGE>
to consolidate their inventory and product procurement systems could cause
fluctuations or delays in the Company's order patterns. Also, recent efforts in
the cable industry to consolidate as well as to standardize transponders among
status monitoring systems could cause pricing pressure as well as affect
deployment within certain customers of the Company's cable products. These
standards were adopted by the standards setting body in the year 2001 and may
adversely affect the Company's revenues from such products in the year 2002 and
in subsequent periods. In addition, markets for the Company's LIGHTHOUSE
products have been, and may continue to be, difficult for the foreseeable
future. The Company cannot predict such future events or business conditions
and the Company's results could be adversely affected by these industry trends
in the primary markets its serves.

International sales in the second quarter ended June 29, 2002 were approximately
6% of total revenues and the Company believes that certain international markets
may offer further opportunities. The addition of the LoopCare software product
line has enhanced the Company's capability to penetrate this market. The Company
recorded its initial LoopCare Software sale in the international market in the
first quarter of 2002 with two additional sales in the second quarter of 2002.
However, the international telephony markets differ from those found
domestically due to the different types and configurations of equipment used by
those international communication companies to provide services. In addition,
certain competitive elements also are found internationally which do not exist
in the Company's domestic markets. These factors, when combined, have made
entrance into these international markets very difficult. From time to time, the
Company has utilized the professional services of various marketing consultants
to assist in defining the Company's international market opportunities. With the
assistance of these consultants and through direct marketing efforts by the
Company, it has been determined that its present MCU technology offers limited
opportunities in certain international markets for competitive and other
technological reasons. The Company continues to evaluate opportunities for its
other products including its LoopCare Software products in international
markets. However, there can be no assurance that any continued efforts by the
Company will be successful or that the Company will achieve significant
international sales.

The Company believes that its future growth will be affected as a result of the
continuing economic slowdown in the telecommunications industry whereby
established RBOC and large ILEC customers are becoming even more conservative in
their capital spending with direct impact on ordering patterns and quantities.
The Company believes that the RBOC and large ILEC customers are being adversely
affected by deteriorating line growth and the after-effects of overspending in
1999 and 2000, as well as competition from cable and wireless carriers and other
carriers entering the local telephone service market. In addition, certain
emerging carriers are continuing to be hampered by financial instability caused
in large part by a lack of access to capital. Due to this uncertainty, the
Company will continue to evaluate its investments in production, marketing and
research and development expenses and monitor, control or decrease expense
levels, as appropriate.

The Company also believes that continued growth will depend, in part, on its
ability to design and engineer new products and, therefore, spends a significant
amount on research and development. Research and development expenses as a
percentage of revenues were 23% for the second quarter of 2002 compared to 13%
for the second quarter of 2001.

                    RESULTS OF OPERATIONS - SECOND QUARTER

Revenues

Revenues for the second quarter of 2002 of $14,583,910 were $7,192,257, or 33%,
lower than the revenues of $21,776,167 reported for the second quarter of 2001.
The revenue performance by product line for the second quarter of 2002 compared
to the prior year period follows.

The decrease in revenues for the second quarter of 2002 resulted primarily from
slower deployments of the MCU product-line caused by the continuing budget
restrictions of the RBOCs, as well as the effects from negative line growth and
diminishing DLC deployment. This decrease in sales of the MCU product line
resulted from decreased sales to all RBOCs, which is primarily associated with
slow-downs in capital spending programs to upgrade DLC systems within certain
regions with MCU technology. Further, as the product life cycle for the MCU
product continues to mature, there is a continuing possibility that customer
requirements for certain legacy MCU products may be satisfied at some point.
Sales of the Company's core MCU products, which decreased by $7,518,000 between
the quarterly periods, comprised 52% of total second quarter 2002 revenues
compared to 68.9% for the year earlier quarter.

Sales of Tollgrade's DigiTest system products, which include LoopCare software,
declined substantially between quarterly periods due to a decline in sales of
DigiTest hardware to Sprint USA as a result of the discontinuation of their ION
project. Sales of DigiTest products represented 6.9% of total revenue for the
quarter. In addition, sales of the Company's DAU product line were insignificant
during the second quarter 2002 as a result of the discontinuation of Sprint's
ION project.

Sales of stand alone LoopCare software products of $2,321,679 for the second
quarter of 2002 were made primarily to RBOC customers and certain international
customers. The Company acquired this product line from Lucent Technologies, Inc.
on September 30, 2001 and thus had no comparable sales in the second quarter of
2001. These sales comprised 15.9% of total revenues during the second quarter of
2002.

The Company's second quarter 2002 service revenues were $2,566,149, which
represents 17.6% of total quarterly revenue and an increase of $1,967,000 over
the second quarter of 2001. The increase is primarily due to the inclusion of
$1,889,631 from software maintenance related to the new LoopCare product line.
The balance of professional services revenue relates to installation oversight
and project management services. Service revenues were provided primarily to
RBOC customers.

LIGHTHOUSE cable product sales increased $573,000 or 135.5% between quarters due
primarily to the deployment of the Company's Version 5 LIGHTHOUSE software by
AT&T BIS. Sales of LIGHTHOUSE cable status monitoring system products amounted
to 6.8% of total second quarter 2002 revenue.

Periodic fluctuations in customer orders and backlog result from a variety of
factors, including but not limited to, the timing of significant orders from,
shipments to, and acceptance of software by the RBOCs, and are not necessarily
indicative of long-term trends in sales of the Company's products.

Gross Profit

Gross profit for the second quarter of 2002 was $8,449,143 compared to
$12,210,617 for the second quarter of 2001, representing a decrease of
$3,761,474, or 30.8%. Gross profit as a percentage of revenues

                                      20
<PAGE>
increased to 57.9% in the second quarter of 2002, compared to 56.1% in the same
quarter last year. The overall increase in gross profit as a percentage of
sales resulted primarily from higher margins associated with the sales of
LoopCare software products, offset by increased cost per unit sold due to
substantially lower hardware production, the product mix of hardware sales
during the quarter relative to last year and $600,000 provided for slow moving
inventory. The majority of this inventory related to products manufactured by
Tollgrade for OEM partners who have seen substantial declines in business
levels as a result of current difficult market conditions. The Company will
continue to monitor and aggressively manage its inventory stock, but there can
be no assurances made that further provisions for slow moving inventory will
not be required. The Company's gross margin is and will continue to be highly
sensitive to the mix of products shipped, the level of operations and the level
of reserves required for slow moving and obsolete inventory should current
difficult economic conditions persist.

Selling and Marketing Expense

Selling and marketing expense for the second quarter of 2002 was $2,224,833
compared to $2,492,496 for the second quarter of 2001. This decrease of $267,663
or 10.7%, is primarily due to decreases in commissions, reversal of incentive
compensation accruals provided in the first quarter of 2002 of $58,900 and
decreases in various promotions and related marketing programs offset by
increases caused by the addition of LoopCare personnel. As a percentage of
revenues, selling and marketing expenses increased to 15.3% in the second
quarter of 2002 from 11.4% in the second quarter of 2001.

General and Administrative Expense

General and administrative expense for the second quarter of 2002 was
$1,268,594, an increase of $206,448, or 19.4%, from the $1,062,146 recorded in
the second quarter of 2001. The increase is attributable to the addition of
LoopCare and other personnel, higher general insurance costs and higher
professional services expenses associated with the annual report and 10-K,
partially offset by the reversal of incentive compensation accruals provided in
the first quarter of 2002 of $46,500. As a percentage of revenues, general and
administrative expenses increased to 8.7% in the second quarter of 2002 from
4.9% in the second quarter of 2001.

Research and Development Expense

Research and development expense in the second quarter of 2002 was $3,396,069,
an increase of $646,964, or 23.5%, over the $2,749,105 recorded in the second
quarter of 2001. The increase is primarily associated with the addition of
approximately 29 engineering personnel resulting from the LoopCare acquisition
along with other associated expenses. This increase was partially offset by the
reversal of incentive compensation accruals provided in the first quarter of
2002 of $100,000. As a percentage of revenues, research and development expense
increased to 23.3% in the second quarter of 2002 from 12.6% in the second
quarter of 2001.

Severance and Related Expense

On April 19, 2001, the Company announced a cost realignment initiative. The
restructuring program resulted in workforce reduction charges of $400,000 (not
included in above expense categories) in the second quarter of 2001 related to
the cost of severance and related benefits for the termination of approximately
80 employees, as well as exit costs consisting of consulting and legal fees.

Interest and Other Income

Interest and other income consists of interest income in both quarterly periods.
For the second quarter of 2002, interest and other income was $200,000 compared
to $790,558 for the second quarter of 2001, a

                                      21
<PAGE>
decrease of $590,558, or 74.7%.  This decrease is primarily a result of the
decrease in funds available for investments due to the LoopCare acquisition for
$62,029,000 in cash at the beginning of the fourth quarter of 2001.

Provision for Income Taxes

The provision for income taxes for the second quarter of 2002 was $668,794, a
decrease of $1,825,208 or 73.2% from the $2,494,002 recorded for the second
quarter of 2001. The effective income tax rate for both periods was
approximately 38% of pretax income.

Net Income and Earnings Per Share

As a result of the above factors, net income for the second quarter of 2002 was
$1,090,853, a decrease of $2,712,573, or 71.3%, from the $3,803,426 recorded in
the second quarter of 2001. Basic and diluted earnings per common share of $.08
for the second quarter of 2002 decreased by $.21 and $.20, or 72.4% and 71.4%,
from the $.29 and $.28, respectively, earned in the second quarter of 2001.
Basic and diluted weighted average common and common equivalent shares
outstanding were 13,088,748 and 13,339,053, respectively, in the second quarter
of 2002 compared to 13,028,498 and 13,404,290, respectively, in the second
quarter of 2001. As a percentage of revenues, net income for the second quarter
of 2002 decreased to 7.5% compared to 17.5% for the second quarter of 2001.

                       RESULTS OF OPERATIONS YEAR-TO-DATE

Revenues

For the first six months of 2002, revenues were $32,106,184 compared to
$49,766,169 for the first six months of 2001, representing a decrease of
$17,659,985, or 35.5%. The revenue performance by product line for the first six
months of 2002 compared to the prior year period follows.

The decrease in revenues for the first six months of 2002 resulted primarily
from slower deployments of the MCU product line caused by the continuing budget
restrictions of the RBOCs as well as the effects from negative line growth and
diminishing DLC deployment. This decrease in sales of the MCU product line
resulted from decreased sales to all RBOCs, which is primarily associated with
slowdowns in capital spending programs to upgrade DLC systems within certain
regions with MCU technology. Further, as the product life cycle for the MCU
product continues to mature, there is a continuing possibility that customer
requirements for certain legacy MCU products may be satisfied at some point. For
similar reasons, the Company's OEM resellers shipped fewer Digital Loop Carrier
systems to their end customers, which reduced MCU product sales to these
customers. Sales of the Company's core MCU products, which decreased by
$17,553,000 between the six-month periods, comprised 53.1% of total revenue for
the first six months of 2002 compared to 69.5% for the year earlier period.

Sales of Tollgrade's DigiTest system products, which include LoopCare software,
declined substantially ($6,945,000) between six-month periods due to a lack of
sales of DigiTest hardware to Nortel for international applications and a
decline in sales to Sprint USA as a result of the discontinuation of their ION
project. Sales of DigiTest products represented 7.0% of total revenue for the
first six months of 2002. In addition, sales of the Company's DAU product line
were insignificant during the first six months of 2002 as a result of the
discontinuation of Sprint's ION project.

Sales of stand alone LoopCare software products of $5,741,622 for the first six
months of 2002 were made primarily to RBOC customers and certain international
customers. The Company acquired this product

                                      22
<PAGE>
line from Lucent Technologies, Inc.  on September 30, 2001 and thus had no
comparable sales in the first six months of 2001. These sales comprised 17.9%
of total revenues during the first six months of 2002.

The Company's service revenues for the first six months of 2002 were $5,138,720,
which represents 16.0% of total six-month revenue and an increase of $4,014,000
over the similar period in 2001. The increase is due to the inclusion of
$3,877,672 from software maintenance related to the new LoopCare product line.
The balance of professional services revenue relates to installation oversight
and project management services. Service revenues were provided primarily to
RBOC customers.

LIGHTHOUSE cable product sales were $1,666,660 during the first six months of
2002, a decrease of 8.9% or $162,000 from the prior year period. These sales
amounted to 5.2% of total second quarter 2002 revenue.

Gross Profit

Gross profit for the first six months of 2002 was $18,589,159 compared to
$27,926,336 for the first six months of 2001, representing a decrease of
$9,337,177, or 33.4%. Gross profit as a percentage of revenues increased to
57.9% in the first six months of 2002, compared to 56.1% in the same period last
year. The overall increase in gross profit as a percentage of sales resulted
primarily from higher margins associated with the sales of LoopCare software
products, offset by increased cost per unit sold due to substantially lower
hardware production, the product mix of hardware sales during the period
relative to the previous period and $1,163,000 provided for slow moving and
obsolete inventory and warranty items amounting to $250,000. The majority of
this inventory related to products manufactured by Tollgrade for OEM partners
who have seen substantial declines in business levels as a result of current
difficult market conditions. The Company will continue to monitor and
aggressively manage its inventory stock, but there can be no assurances made
that further provisions for slow moving inventory will not be required. The
Company's gross margin is and will continue to be highly sensitive to the mix of
products shipped, the level of operations and the level of reserves required for
slow moving and obsolete inventory should current difficult economic conditions
persist.

Selling and Marketing Expense

Selling and marketing expense for the first six months of 2002 was $4,642,142
compared to $4,942,320 for the six months of 2001. This decrease of $300,178 or
6.1%, is primarily due to decreases in commissions and decreases in various
promotions and related marketing programs offset by increases caused by the
addition of LoopCare personnel. As a percentage of revenues, selling and
marketing expenses increased to 14.5% in the first six months of 2002 from 9.9%
in the same period last year.

General and Administrative Expense

General and administrative expense for the first six months of 2002 was
$2,794,845, an increase of $202,547, or 7.8%, from the $2,592,298 recorded in
the first six months of 2001. The increase is attributable to the addition of
LoopCare and other personnel, higher general insurance costs and higher
professional services expenses associated with the annual report and Form 10-K.
As a percentage of revenues, general and administrative expenses increased to
8.7% in the second quarter of 2002 from 5.2% in the same period of 2001.

Research and Development Expense

Research and development expense for the first six months of 2002 was
$7,390,710, an increase of $1,282,064 or 21.0%, over the $6,108,646 recorded in
the first six months of 2001. The increase is

                                      23
<PAGE>
primarily associated with the addition of approximately 29 engineering
personnel resulting from the LoopCare acquisition along with other associated
expenses. As a percentage of revenues, research and development expense
increased to 23.0% in the first six months of 2002 from 12.3% in the similar
period of 2001.

Severance and Related Expense

On April 19, 2001, the Company announced a cost realignment initiative. The
restructuring program resulted in workforce reduction charges of $400,000 (not
included in above expense categories) in the second quarter of 2001 related to
the cost of severance and related benefits for the termination of approximately
80 employees, as well as exit costs consisting of consulting and legal fees.

Interest and Other Income

Interest and other income consists of interest income in both semiannual
periods. For the first six months of 2002, interest and other income was
$437,999 compared to $1,697,535 for the first six months of 2001, a decrease of
$1,259,536, or 74.2%. This decrease is primarily a result of the decrease in
funds available for investments due to the LoopCare acquisition for $62,029,000
in cash at the beginning of the fourth quarter of 2001.

Provision for Income Taxes

The provision for income taxes for the first six months of 2002 was $1,595,794,
a decrease of $4,426,218 or 73.5% from the $6,022,012 recorded for the first six
months of 2001. The effective income tax rate for both periods was approximately
38% of pretax income.

Net Income and Earnings Per Share

As a result of the above factors, net income for the first six months of 2002
was $2,603,667, a decrease of $6,954,928, or 72.8%, from the $9,558,595 recorded
in the first six months of 2001. Basic and diluted earnings per common share of
$.20 and $.19, respectively, for the first six months of 2002 decreased by $.54
and $.52, or 73.0% and 73.2%, from the $.74 and $.71, respectively, from that
earned in the first six months of 2001. Basic and diluted weighted average
common and common equivalent shares outstanding were 13,099,106 and 13,386,081,
respectively, in the first six months of 2002 compared to 12,993,558 and
13,391,030 respectively, in the first six months of 2001. As a percentage of
revenues, net income for the first six months of 2002 decreased to 8.1% compared
to 19.2% for the first six months of 2001.

Periodic fluctuations in customer orders and backlog result from a variety of
factors, including but not limited to, the timing of significant orders from,
shipments to, and acceptance of software by the RBOCs, and are not necessarily
indicative of long-term trends in sales of the Company's products.

CRITICAL ACCOUNTING POLICIES

The Company's financial statements are prepared in conformity with accounting
principles generally accepted in the United States of America. Certain of these
accounting principles are more critical than others in gaining an understanding
of the basis upon which the Company's financial statements have been prepared. A
comprehensive review of these policies is contained in the Company's 2001 Annual
Report on Form 10-K filed on March 22, 2002. There have been no significant
changes in these policies or the application thereof during the second quarter
of 2002.

LIQUIDITY AND CAPITAL RESOURCES

At June 29, 2002, the Company had working capital of $69,753, 700 which
represented an increase of $2,125,549 or 3.1%, from the $67,628,151 of working
capital as of December 31, 2001. The increase in working capital is a result of
operating cash flows and proceeds from the exercise of stock options exceeding
cash requirements for the purchase of property and equipment and approximately
$1,625,000 of treasury stock.

The Board of Directors has authorized the continuation of a share repurchase
program it started in 1997. Under the current extension, the Company may
repurchase a total of one million shares of its common stock before December 31,
2002. Since the initial repurchase program was instituted in April of 1997, and
as of June 29, 2002, the Company has repurchased 461,800 shares of common stock.
The repurchased shares are authorized to be utilized under certain employee
benefit programs. The number of shares the Company intends to purchase and the
timing of such purchases will be determined by the Company at its discretion.
The Company will use existing cash and short-term investments to finance the
purchases.

Effective December 20, 2001, the Company executed a five-year $25.0 million
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. Commitment fees are payable
quarterly at 0.25% of the unused commitment. As of June 29, 2002, there were no
outstanding borrowings under the Facility and the Company is in compliance with
all debt covenants. No borrowings for working capital are currently anticipated,
as the Company believes internally generated funds will be sufficient to sustain
working capital requirements for the foreseeable future.

The Company's days sales outstanding (DSO's) in accounts receivable trade, based
on the past twelve months rolling revenue, was 64 and 43 days as of June 29,
2002 and December 31, 2001, respectively. The increase is a direct result of a
substantial amount of sales in June of 2002 compared to December of 2001. The
Company's inventory turnover ratio was 1.2 turns and 1.3 turns for June 29, 2002
and December 31, 2001, respectively. Management believes that operating cash
flow and cash reserves are adequate to finance currently planned capital
expenditures and to meet the overall liquidity needs of the Company.

Quantitative and Qualitative Disclosures about Market Risk

The Company's current investment policy limits its 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. The Company believes it minimizes its
risk 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. The Company holds its investment securities to maturity
and believes 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.

Other Matters

On September 30, 2001, the Company acquired certain assets and assumed certain
liabilities of the LoopCare Product line from Lucent Technologies, Inc.
("Lucent") for approximately $62,029,000 in cash which includes approximately
$2,200,000 of acquisition-related costs. The acquisition has been recorded under
the purchase method of accounting and, accordingly, the results of operations of
the LoopCare product line since October 1, 2001 have been included in the
consolidated financial statements.

The Company has 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. In connection with the acquisition,
$45,800,000 of intangible assets was identified, of which $7,300,000 were
related to capitalized software and determined to have a definite life, while
the remaining $38,500,000 of the identified intangible assets, as well as
goodwill of approximately $16,162,000, are not being amortized as they have been
determined to have an indefinite useful life.

As of January 1, 2002, the Company fully adopted the provisions of SFAS No. 142.
SFAS 142 requires that goodwill be analyzed for impairment under a two-step
process. The first step of the goodwill impairment test is to identify potential
impairment by comparing the fair value of the reporting unit with its carrying
amount, including goodwill. The second step, used to measure the potential
impairment loss of the goodwill, is to compare the implied fair value of the
reporting unit goodwill with the carrying amount of that goodwill. The Company
has determined that it has only one reporting segment and has completed the
first step of the goodwill impairment test as of June 29, 2002 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
goodwill carrying value and, accordingly, step two of the test was not required.
Future changes in circumstances, including a sustained decline in the aggregate
market value of the Company's stock, could necessitate a reconsideration of
whether an impairment of goodwill carrying value has occurred.

Developed product software costs are being amortized over a five-year useful
life. An annual review for impairment of these assets will be made following the
guidance of paragraphs 4-11 of SFAS 121. Specifically, the sum of the
undiscounted future cash flows expected to be derived from the developed product
software will be compared with the net book carrying value. If the carrying
value is greater than the sum of the projected cash flows, impairment loss will
be recorded equal to the excess of the carrying value over the fair value of the
assets. The fair value will be determined by a separate test utilizing the
discounted present value of the expected cash flow stream from the software.

In addition, other intangible assets that are not subject to amortization will
be tested for impairment annually or more frequently if events or changes in
circumstances indicate that the asset might be impaired. The impairment test for
non-amortizable intangible assets will consist of a comparison of the fair value
of an intangible asset with its carrying amount. The Company intends to test the
value of intangible assets other than goodwill as of December 31, 2002 using the
same testing methodology employed by independent consultants in making the
initial valuation in 2001. Specifically, the relief-from-royalty method will be
used to test the value of the LoopCare trade name and discounted cash flow
analyses will be used to value the base software and post warranty maintenance
service agreements.

                                      26
<PAGE>
As previously discussed, at the date of the LoopCare acquisition, the Company
established a non-amortizing intangible asset based primarily on the value of
RBOC service maintenance agreements whose fees are fixed and which renewal is
assumed to be for perpetuity. One of the Company's four RBOC customers has
recently notified the Company of its intention to negotiate a need based, time
and materials fee instead of the fixed maintenance fee when its current service
agreement expires on December 31, 2002. The Company has agreed to negotiate in
good faith towards this type of arrangement but fully intends to maintain the
value of this contract. Therefore, at this point, the Company believes the value
and non-amortizing characteristics of this intangible asset to be preserved.
However, if through negotiations, a new maintenance agreement with the RBOC
customer cannot be reached, or if a new agreement is reached that is believed
will result in less revenue to the Company than the current fixed fee agreement,
the current fair value of the maintenance service agreements may be determined
to be less than the $32,000,000 carrying value, perhaps materially so, resulting
in a charge against operating income for 2002 and/or commencement of
amortization of the remaining fair value over its determined useful life. A
similar analysis of the fair value of the maintenance service agreements could
be required if any of the Company's RBOC customers reduce or terminate their
maintenance service agreements due to the RBOC customers' own financial
difficulties.

BACKLOG

The Company's backlog consists of firm customer purchase orders and signed
software maintenance agreements. As of June 29, 2002, the Company had a backlog
of $7,394,925 compared to $4,936,448 at December 31, 2001 and $5,605,349 at
March 31, 2001. The June 29, 2002 backlog includes approximately $4,227,517
related to software maintenance contracts. This maintenance and support will be
provided for and billed on a straight-line basis through the remaining terms of
the agreements. Including the scheduled maintenance services, approximately 53%
of the current backlog is expected to be recognized as revenue in the third
quarter of 2002. 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. While these fluctuations could impact
short-term results, they are not necessarily indicative of long-term trends in
sales of the Company's products.
