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

The statements contained in this Annual Report on Form 10-K, specifically those
contained in Item 1 "Business" and Item 7 "Management's Discussion and Analysis
of Financial Condition and Results of Operation," and statements incorporated by
reference into this Form 10-K from the 1998 Annual Report to Shareholders, along
with statements in other reports filed with the Securities and Exchange
Commission, external documents and oral presentations, which are not historical
are "forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended. These forward-looking statements represent Tollgrade
Communications, Inc.'s (the "Company") present expectations or beliefs
concerning future events. The Company cautions that such statements are
qualified by important factors that could cause actual results to differ
materially from those in the forward-looking statements. Results actually
achieved may differ materially from expected results included in these
statements. Those factors which specifically relate to the Company's business
include the following: rapid technological change along with the need to
continually develop new products; dependence on a single product line;
competition; dependence on key employees; management of Company's growth;
dependence on certain customers; dependence on certain suppliers; proprietary
rights and risks of third party claims of infringement; and government
regulation.

ITEM 1. BUSINESS.

         The Company was incorporated in Pennsylvania in 1986 and began
operations in 1988. Its principal offices are located at 493 Nixon Road,
Cheswick, Pennsylvania 15024 and its telephone number is (724) 274-2156.

         The Company designs, engineers, markets and supports test access and
test extension products for the telecommunications and cable television
industries. The Company's telecommunication proprietary 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
includes lines for popular devices such as computer modems and fax machines.
POTS excludes the more complex lines, such as data communications service lines,
commonly referred to as "special services."

         POTS line test systems, located at telephone companies' central
offices, diagnose problems in the "local loop", which is the portion of the
telephone network which connects end users to a telephone company's central
office, and is comprised primarily of copper wireline. The ability to remotely
test reduces the time needed to identify and resolve problems and eliminates or
reduces the cost of dispatching a technician to the problem site. Most POTS line
test systems were designed for use over copper wireline only, so that the
introduction of fiber-optic technology into the local loop renders it
inaccessible to these test systems. The Company's metallic channel unit
("MCU(R)") products solve this problem by extending test-system access through
the fiber-optic portion into the copper portion of the local loop.

         Products. The Company's MCU products plug into the digital loop carrier
("DLC") systems that are large systems manufactured by equipment vendors such as
Lucent (formerly part of AT&T), that are used by telephone companies to link the
copper and fiber-optic portions of the local loop. DLC systems are located at
the telephone company central offices and at remote sites within a local user
area, and effectively multiplex the services of the copper lines into a single
fiber-optic line. In many instances, several DLC systems are located at a single
remote site to serve several thousand different end-user homes and offices.
Generally, for every DLC remote site, two MCU line testing products are
deployed. To ensure compatibility with these DLC systems, the Company pays
royalties pursuant to license agreements for the use of proprietary design
integrated circuits ("PDICs"). The PDICs are the design and property of



                                       2
<PAGE>   3

the DLC system manufacturer from which they are purchased. The Company maintains
license agreements with and pays royalties to Lucent Technologies, Fujitsu
Network Transmission Systems, Inc., NEC American, Inc. and Reliance Comm/Tec
Corporation. In general, the current terms for expiration of these agreements
range at various times between August 1999 and an indefinite duration, with
renewal provisions (unless earlier terminated) for periods of between one and
five years. In addition, certain of these agreements can be terminated prior to
renewal. The Company incurred $1,893,000, $2,014,000 and $2,069,000 respectively
in 1996, 1997 and 1998 as royalties under the license agreements, which
royalties are calculated either based on a percentage of the list price of MCU
products or a fixed amount per unit which incorporate the technology licensed
under each such agreement. Certain of the license agreements require the Company
to maintain the confidentiality of the licensor's proprietary information and/or
the terms and conditions of the agreement itself. In addition, the Company
maintains license agreements which do not contain royalty provisions with
Advanced Fibre Communications, DSC Technologies Corporation, Northern Telecom
Inc., UTSTARCOM, Inc., Next Level Communications and SAGEM SA (a French
corporation). The expiration dates of these agreements range at various times
between May 1999 and November 2004, with renewal provisions (unless earlier
terminated) for periods of one or more years. Future license agreements entered
into by the Company may contain terms comparable to, or materially different
than, the terms of existing agreements as competitive and other conditions
warrant. The loss of PDICs license agreements or the inability of the Company to
maintain an adequate supply of PDICs could have a material adverse effect on the
Company's business. Other MCU technology is also used with home and business
alarm systems. As with home service line testing, home alarm systems must be
monitored from the alarm company's headquarters along a hybrid copper and
fiber-optic line. The Company's alarm-related MCU products are used to
facilitate the transport of analog alarm signals from subscriber homes to alarm
company monitoring stations across the hybrid telephone network. These units
plug into equipment at both central office and remote locations. MCU products
accounted for more than 93%, 94% and 90% of the Company's sales in 1996, 1997
and 1998, respectively.

         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 has entered
into a license agreement with C-Cor Electronics, Inc. (a cable television
systems developer) in which the Company provides its status monitoring
transponder technology that is incorporated into C-Cor's cable network
management system. In 1998, the Company, under certain other business
arrangements, also shipped cable products to ANTEC and General Instrument.

         Product and Technology Development. The Company's product development
personnel are organized into teams, each of which is effectively dedicated to a
specific product line(s) or technology. Each product team also implements the
Company's ongoing "value engineering" programs which are designed to replace the
Company's products with successive generations having additional features and/or
lower costs. The Company continuously monitors developing technologies and
introduces products as defined standards and markets emerge. In addition, the
Company continues to investigate the development of new applications for its MCU
technology and other technologies to service the telecommunications industry.
During 1996, 1997 and 1998, research and development expenses were approximately
$3,921,000, $5,945,000 and $6,880,000, respectively.

         Proprietary Rights. The names "Tollgrade(R)", "MCU(R)" and
"Micro-Bank(R)", and the Company's corporate logo are registered trademarks of
the Company. "Team Tollgrade(SM)" is a service mark of the Company. The Company
has also applied for trademark registration for "Lighthouse(TM)", "Digitest(TM)"
and "Telaccord(TM)". The Company has obtained three patents on the MCU products
with expiration dates ranging from 2010 to the year 2014. In addition, the
Company has two U.S. provisional, two United States, one Canada and three
international patent cooperation treaty ("PCT) patent applications pending. The
Company will seek additional patents from time to time related to its research
and development activities. The Company protects its trademarks, patents,
inventions, trade secrets, and other proprietary rights by contract, trademark,
copyright and patent registration, and internal security.


                                       3

         Customers. The Company's primary telecommunication customers are the
five regional Bell operating companies ("RBOCs"), which are Ameritech
Corporation, Bell Atlantic Corporation, BellSouth Corporation, SBC
Communications Inc., and US WEST Inc., as well as major independent telephone
companies such as Sprint. Historically, almost all of the Company's sales have
been made to the RBOCs (79% in 1998). Bell Atlantic Corporation and BellSouth
Corporation accounted for 29% and 25%, respectively, of the Company's total
sales in 1998. The Company's primary cable product customers are Original
Equipment Manufacturers ("OEM") cable equipment manufacturers such as C-Cor
Electronics, Inc., ANTEC and General Instruments. Sales of the Company's cable
products in 1998 were less than [2%] of total revenues. The Company's
relationships with its customers are material to the Company's business, and the
loss of any such relationship could have a material adverse effect on the
Company's business.

         Manufacturing. The Company's manufacturing operations consist primarily
of quality control, functional testing, final assembly, burn-in and shipping.
The Company is ISO 9001 registered from 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"), it 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.

         The Company utilizes two 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 to, 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.

         The Company currently procures all of its components from outside
suppliers. Generally, the Company uses industry standard components for its
products. Application specific integrated circuits ("ASICs") are a key component
to the manufacturing process and are custom made to the Company's
specifications. Although the Company has 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.


         Backlog. The Company's backlog at December 31, 1998 was approximately
$0.6 million, as compared to approximately $1.6 million at December 31, 1997. At
December 31, 1998, the composition of the backlog related primarily to one
customer order, while backlog at December 31, 1997 consisted of several customer
orders. 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. Because of the quick turnaround that the customers expect
on their orders, which is sometimes one to two weeks, and because of the
possibility of customer changes in delivery schedules or cancellation of orders,
the Company's backlog as of any particular date may not be indicative of actual
revenues expected for any future period.


         Competitive Conditions. The deciding 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. The Company believes that it competes favorably on all of these
factors, and certain of its products have proprietary or patented features. The
Company also attempts to enter into development agreements for its MCU products
with the manufacturers of DLC and other complex systems, which serves to ensure
compatibility for its products. Competition would increase if new companies
enter the Company's product markets or existing competitors expand their product
lines. For instance, the telecommunications reform legislation has lifted the
restrictions which previously prevented the RBOCs from manufacturing
telecommunications equipment. Pursuant to this legislative


                                       4
<PAGE>   5

reform, the RBOCs, which are the Company's largest customers, may become
competitors of the Company in the markets served by the Company.

         For the Company's line-testing MCU devices, the primary competitive
products are the remote monitoring units made by Teradyne, Inc. and the Harris
Dracon division of Harris Corporation. In addition, the Wiltron Company, Inc.
offers the Wiltron LoopMATE(R), a modular remote test head, which competes with
the Company's POTS testing capabilities. The Company's MCU is simpler and less
costly to install and permits the full complement of centralized testing to be
performed as quickly and accurately as with copper by-pass wiring. The Company
believes that the Tau-Tron division of General Signal Corporation, which
provides special services test systems, could also expand into POTS line
testing. The alarm-related MCU product's primary competitor is the Turbo 2000
unit made by ANTEC Corporation. For the Company's cable products, the primary
competitors for status monitoring are Cheetah Technologies and AM
Communications, Inc.

         Employees. At December 31, 1998, the Company had 230 full-time
employees, all in the United States. None of the Company's employees are
represented by a collective bargaining agreement.

         Government Regulation. The telecommunications industry is subject to
regulation in the United States and other countries. Federal and state
regulatory agencies, including the FCC and various state public utility
commissions and public service commissions, regulate most of the Company's
domestic customers. While such regulation does not typically affect the Company
directly, the effects of such regulations on the Company's customers may, in
turn, adversely impact the Company's business and operating results.
Governmental authorities also have 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.

ITEM 2.  PROPERTIES.

         The Company's headquarters and principal administrative, engineering
and assembly facilities are located in Cheswick, Pennsylvania and occupy
approximately 104,400 square feet. The Company occupies its current facilities
under a lease that expires in December, 2001 with an option to renew the term of
the lease for one additional period of three years. The Company believes that
its current facilities are adequate to support its present level of operations
and there is ample room to support continued sales growth for the foreseeable
future.

ITEM 3.  LEGAL PROCEEDINGS.

         There are currently no outstanding or pending material legal
proceedings with respect to the Company or its business.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         During the fourth quarter of 1998, there were no matters submitted to a
vote of security holders through solicitation of proxies or otherwise.

                            Corporation Law of 1998)

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


         In compliance with the requirements of Section 1522(c) of Pennsylvania
Business Corporation Law of 1988 (the "BCL"), Tollgrade Communications, Inc., a
corporation organized and existing under the BCL (the "Corporation"), hereby
certifies that:

         1. The name of the Corporation is Tollgrade Communications, Inc.

         2. The resolution ("Resolution") duly adopted by the Board of Directors
of the Corporation establishing and designating a series of the Corporation's
Preferred Stock, par value $1.00 per share, and fixing and determining the
relative rights and preferences thereof is as follows:

         RESOLVED, that pursuant to the authority granted to and vested in the

Directors" or the "Board") in accordance with the provisions of the Amended and
Restated Articles of Incorporation, the Board of Directors hereby creates a
series of Preferred Stock, par value $1.00 per share (the "Preferred Stock"), of

resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the

issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

         Section 2. Dividends and Distributions.

         (A) Subject to the rights of the holders of any shares of any series of
Preferred Stock (or any similar stock) ranking prior and superior to the Series
A Preferred Stock with respect to dividends, the holders of shares of Series A
Preferred Stock, in preference to the holders of Common Stock, par value $0.20
per share (the "Common Stock"), of the Corporation, and of any other junior
stock, shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for the purpose, quarterly dividends
payable in cash on the first day of March, June, September and December in each
year (each such date being referred to herein as a "Quarterly Dividend Payment
Date"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the greater of (a) $1 or
(b) subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate per share amount of all cash dividends, and 100 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions, other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock payable in shares of Common Stock, or
effect a subdivision or combination or consolidation of the outstanding shares
of Common Stock (by reclassification or otherwise than by payment of a dividend
in shares of Common Stock) into a greater or lesser number of shares of Common
Stock, then in each such case the amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under clause (b)
of the preceding sentence shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         (B) The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in subsection (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1 per share on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

         (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, unless the date of issue of such



                                       2
<PAGE>   3


shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued by unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

         Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Preferred Stock shall entitle the holder thereof to 100 votes
on all matters submitted to a vote of the shareholders of the Corporation. In
the event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock that were outstanding immediately prior to such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         (B) Except as otherwise provided herein, in any other Statement With
Respect to Shares creating a series of Preferred Stock or any similar stock, or
by law, the holders of shares of Series A Preferred Stock and the holders of
shares of Common Stock and any other capital stock of the Corporation having
general voting rights shall vote together as one class on all matters submitted
to a vote of shareholders of the Corporation.


                                       3
<PAGE>   4

         (C) Except as set forth herein, or as otherwise provided by law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

         Section 4. Certain Restrictions.

         (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:


                  (i) declare or pay dividends, or make any other distributions,
         on any shares of stock ranking junior (either as to dividends or upon
         liquidation, dissolution or winding up) to the Series A Preferred
         Stock;

                  (ii) declare or pay dividends, or make any other
         distributions, on any shares of stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Preferred Stock, except dividends paid ratably on the Series A
         Preferred Stock and all such parity stock on which dividends are
         payable or in arrears in proportion to the total amounts to which the
         holders of all such shares are then entitled;

                  (iii) redeem or purchase or otherwise acquire for
         consideration shares of any stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the Series
         A Preferred Stock, provided that the Corporation may at any time
         redeem, purchase or otherwise acquire shares of any such junior stock
         in exchange for shares of any stock of the Corporation ranking junior
         (either as to dividends or upon dissolution, liquidation or winding up)
         to the Series A Preferred Stock; or

                  (iv) redeem or purchase or otherwise acquire for consideration
         any shares of Series A Preferred Stock, or any shares of stock ranking
         on a parity with the Series A Preferred Stock, except in accordance
         with a purchase offer made in writing or by publication (as determined
         by the Board of Directors) to all holders of such shares upon such
         terms as the Board of Directors, after consideration of the respective
         annual dividend rates and other relative rights and preferences of the
         respective series and classes, shall determine in good faith will
         result in fair and equitable treatment among the respective series or
         classes.


                                       4
<PAGE>   5

         (B) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under subsection (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.


         Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of the same or a new series of
Preferred Stock subject to the conditions and restrictions on issuance set forth
herein, in the Amended and Restated Articles of Incorporation, or in any other
Statement With Respect to Shares creating a series of Preferred Stock or any
similar stock or as otherwise required by law.

         Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series A



                                       5
<PAGE>   6


Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount set forth in
the preceding sentence with respect to the exchange or change of shares of
Series A Preferred Stock shall be adjusted by multiplying much [sic] amount by a
fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         Section 8. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

         Section 9. Rank. Except as otherwise set forth in the Amended and
Restated Articles of Incorporation or in the Statement With Respect to Shares
creating another series of Preferred Stock or any other class or series of
stock, the Series A Preferred Stock shall rank, with respect to the payment of
dividends and the distribution of assets, junior to all other series of the
Corporation's Preferred Stock and to any other class or series of stock other
than the Common Stock, whether now existing or hereafter created.

         Section 10. Amendment. The Amended and Restated Articles of
Incorporation of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Preferred Stock so as to affect them adversely without the affirmative
vote of a majority of the votes cast at a meeting of shareholders by the holders
of Series A Preferred Stock, voting together as a single class.

         3. (i) The aggregate number of shares of the Series A Preferred Stock
established and designated by the Resolution is 100,000; (ii) the number of
shares of stock which the Corporation has previously established and designated
pursuant to Section 1522 of the BCL or any corresponding provision of prior law
is hereby reduced to zero; and (iii) the aggregate number of shares authorized
under the Amended and Restated Articles of Incorporation of the Corporation is
35,000,000, of which 10,000,000 shares are Preferred Stock, par value $1.00 per
share, issuable in one or more series, and 25,000,000 shares are Common Stock,
par value $0.20 per share.

         4. The Resolution was duly adopted at a meeting of the Board of
Directors of the Corporation duly called and held on July 23, 1996, at which
meeting a quorum was present and acted throughout.

                                    AGREEMENT

         This Agreement, made as of the 17th day of July, 1997 by and between
TOLLGRADE COMMUNICATIONS, INC., a Pennsylvania corporation (the "Corporation")
and ROGER A. SMITH, an individual residing in the Commonwealth of Pennsylvania
and an employee of the Corporation (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Board of Directors of the Corporation has determined that
it is in the best interests of the Corporation to enter into this Agreement with
the Executive to provide for compensation of the Executive upon termination of
employment under certain circumstances relating to a change in control of the
Corporation; and

         WHEREAS, the Executive desires to obtain such benefits in the event the
Executive's employment is terminated under the circumstances provided herein.

         NOW, THEREFORE, in consideration of the covenants and premises
contained herein, and intending to be legally bound hereby, the parties hereto
agree as follows:

         1. DEFINITION OF TERMS. The following terms when used in this Agreement
shall have the meaning hereafter set forth:

         "ANNUAL SALARY ADJUSTMENT PERCENTAGE" shall mean the mean average
         percentage increase in base salary for all elected officers of the
         Corporation during the two full calendar years immediately preceding
         the time to which such percentage is being applied; provided however,
         that if after a Change-in-Control, as hereinafter defined, there should
         be a significant change in the number of elected officers of the
         Corporation or in the manner in which they are compensated, then the
         foregoing definition shall be changed by substituting for the phrase
         "elected officers of the Corporation" the phrase "persons then
         performing the functions formerly performed by the elected officers of
         the Corporation."

         "CAUSE FOR TERMINATION" shall mean:

         (a)      the deliberate and intentional failure by the Executive to
                  devote substantially his entire business time and best efforts
                  to the performance of his duties (other than any such failure
                  resulting from the Executive's incapacity due to physical or
                  mental illness or disability) after a demand for substantial
                  performance is delivered to the Executive by the Board of
                  Directors which specifically identifies the manner in which
                  the Board of Directors believes that the Executive has not
                  substantially performed his duties,


                                       1
<PAGE>   2


                  or

         (b)      wilfully engaging by the Executive in conduct which
                  constitutes a fraud against the Corporation or a material
                  breach of this Agreement,

                  or

         (c)      the Executive's conviction of any crime which constitutes a
                  felony.

         For purposes of this definition, no act, or failure to act, on the
         Executive's part shall be considered "deliberate and intentional" or
         "willfully" unless done, or omitted to be done, by the Executive not in
         good faith and without reasonable belief that his action or omission
         was in the best interests of the Corporation.

         "CHANGE-IN-CONTROL" shall mean the determination (which may be made
         effective as of a particular date specified by the Board of Directors
         of the Corporation) by the Board of Directors of the Corporation, made
         by a majority vote that a change in control has occurred, or is about
         to occur. Such a change shall not include, however, a restructuring,
         reorganization, merger, or other change in capitalization in which the
         Persons who own an interest in the Corporation on the date hereof (the
         "Current Owners")(or any individual or entity which receives from a
         Current Owner an interest in the Corporation through will or the laws
         of descent and distribution) maintain more than a sixty-five percent
         (65%) interest in the resultant entity. Regardless of the Board's vote
         or whether or not the Board votes, a Change-in-Control will be deemed
         to have occurred as of the first day any one (1) or more of the
         following subparagraphs shall have been satisfied:

         (a)      Any Person (other than the Person in control of the
                  Corporation as of the date of this Agreement, or other than a
                  trustee or other fiduciary holding securities under an
                  employee benefit plan of the Corporation, or a corporation
                  owned directly or indirectly by the stockholders of the
                  Corporation in substantially the same proportions as their
                  ownership of stock of the Corporation), becomes the beneficial
                  owner, directly or indirectly, of securities of the
                  Corporation representing more than thirty five percent (35%)
                  of the combined voting power of the Corporation's then
                  outstanding securities; or

         (b)      The stockholders of the Corporation approve:

                  (i)      A plan of complete liquidation of the Corporation;

                  (ii)     An agreement for the sale or disposition of all or
                           substantially all of the Corporation's assets; or

                  (iii)    A merger, consolidation, or reorganization of the
                           Corporation with or 


                                       2
<PAGE>   3

                           involving any other corporation, other than a merger,
                           consolidation, or reorganization that would result in
                           the voting securities of the Corporation outstanding
                           immediately prior thereto continuing to represent
                           (either by remaining outstanding or by being
                           converted into voting securities of the surviving
                           entity) at least sixty-five percent (65%) of the
                           combined voting power of the voting securities of the
                           Corporation (or such surviving entity) outstanding
                           immediately after such merger, consolidation, or
                           reorganization.

         However, in no event shall a Change in Control be deemed to have
         occurred, with respect to the Executive, if the Executive is part of a
         purchasing group which consummates the Change-in-Control transaction.
         The Executive shall be deemed "part of the purchasing group" for
         purposes of the preceding sentence if the Executive is an equity
         participant or has agreed to become an equity participant in the
         purchasing company or group (except for (i) passive ownership of less
         than five percent (5%) of the voting securities of the purchasing
         company; or (ii) ownership of equity participation in the purchasing
         company or group which is otherwise deemed not to be significant, as
         determined prior to the Change-in-Control by a majority of the
         non-employee continuing Directors of the Board of Directors of the
         Corporation).

         "DATE OF TERMINATION" shall mean:

         (a)      if the Executive's employment is terminated for Disability,
                  the date that a Notice of Termination is given to the
                  Executive;

         (b)      if the Executive terminates due to his death or Retirement,
                  the date of death or Retirement, respectively;

         (c)      if the Executive decides to terminate employment upon Good
                  Reason for Termination, the date following such decision
                  specified by the Corporation after it has been notified of the
                  Executive's decision to terminate employment; or

         (d)      if the Executive's employment is terminated for any other
                  reason, the date on which such termination becomes effective
                  pursuant to a Notice of Termination.

         "DISABILITY" shall mean such incapacity due to physical or mental
         illness or injury as causes the Executive to be unable to perform his
         duties with the Corporation during 180 consecutive days.

         "GOOD REASON FOR TERMINATION" shall mean the occurrence of:

         (a)      without the Executive's express written consent, the
                  assignment to the Executive of any duties materially and
                  substantially inconsistent with his positions, duties,
                  responsibilities and status with the Corporation immediately
                  prior to a Change-in-


                                       3
<PAGE>   4


                  Control, or a material change in his reporting
                  responsibilities, titles or offices as in effect immediately
                  prior to a Change-in-Control, or any removal of the Executive
                  from or any failure to re-elect the Executive to any of such
                  positions, except in connection with the termination of the
                  Executive's employment due to Cause for Termination,
                  Disability or Retirement (as hereinafter defined) or as a
                  result of the Executive's death;

         (b)      (i) a reduction by the Corporation prior to a
                  Change-in-Control in the Executive's base salary unless such
                  reduction is the result of the Board of Directors of the
                  Corporation determining that the Executive has not adequately
                  discharged his duties;

                  (ii) a reduction by the Corporation after a Change-in-Control
                  in the Executive's base salary as in effect immediately prior
                  to any Change-in-Control or a failure by the Corporation after
                  a Change-in-Control to increase the Executive's base salary by
                  the Annual Salary Adjustment Percentage;

         (c)      a failure by the Corporation to continue to provide incentive
                  compensation comparable to that provided by the Corporation
                  immediately prior to any Change-in-Control;

         (d)      a failure by the Corporation after a Change-in-Control to
                  continue in effect any benefit or compensation plan, stock
                  option plan, pension plan, life insurance plan, health and
                  accident plan or disability plan in which the Executive is
                  participating immediately prior thereto (provided, however,
                  that there shall not be deemed to be any such failure if the
                  Corporation substitutes for the discontinued plan, a plan
                  providing the Executive with substantially similar benefits)
                  or the taking of any action by the Corporation which would
                  adversely affect the Executive's participation in or
                  materially reduce the Executive's benefits under any of such

                  enjoyed by the Executive immediately prior to a
                  Change-in-Control (provided, however, that any act or failure

         (f)      any purported termination of the employment of the Executive
                  by the Corporation which is not (i) due to the Executive's
                  Disability, Retirement (as hereinafter defined) or Cause for
                  Termination, or (ii) effected as a Notice of Termination, as
                  defined herein; or

         the specific reason for termination and, if such is claimed to be a
         Cause for Termination or Good Reason for Termination, in reasonable

         for Termination or Good Reason for Termination.

         "OPTIONS" shall mean any stock options issued pursuant to any present
         or future stock option plan of the Corporation.

         date hereof and used in Sections 13(d) and 14(d) thereof, including a

                  Date of Termination (or if the Date of Termination preceded
                  the date of the Change-in-Control, on or before the fifth day

                           future renumeration equal to the product obtained by

                                    (2)      a number equal to the number of
                                             calendar months remaining from the
                                             Date of Termination to the date on
                                             which the Executive is 65 years of
                                             age (or, if earlier, the age agreed
                                             to by the Executive pursuant to any
                                             prior arrangement) divided by

                                             instead of the Date of Termination)

                                             (provided that in the case of

                                             of Termination)

                                      or

                                      (ii)   the average annual cash award
                                             received by the Executive as
                                             incentive compensation or bonus for
                                             one calendar year immediately
                                             preceding the date of the
                                             Change-in-Control.


         5. OUTPLACEMENT SERVICES. If the Executive's employment with the
Corporation should terminate under circumstances as to entitle the Executive to
receive payment hereunder, the Corporation shall reimburse the Executive for any
reasonable fees or other costs incurred by the Executive during the two (2)
years following the Date of Termination in retaining executive placement
agencies, up to a maximum dollar amount not to exceed fifteen percent (15%) of
the 


                                       7
<PAGE>   8


Executive's base salary at the time of such termination. Such reimbursement
shall be made within five (5) days following the Executive's presentment of
bills or other evidence of the costs incurred with executive placement agencies.

         6. TAX IMPLICATIONS. If any payment due to the Executive pursuant to
this Agreement result in a tax being imposed on the Executive pursuant to
Section 4999 of the Internal Revenue Code of 1954, as amended, or any successor
provision ("Section 4999"), then the Corporation shall, at the Executive's
option, either (i) reduce the total payments payable to the Executive to the
maximum amount payable without incurring the Section 4999 tax, or (ii) pay to
the Executive the total amount payable, with the understanding that Section 4999
tax will be due on that total amount.

         7. BENEFITS. If the Executive's employment with the Corporation should
terminate under circumstances as to entitle the Executive to receive payment
hereunder, the Executive shall also be deemed, for purposes of medical
insurance, pension and other benefits of the Corporation, to have remained in
the continuous employment of the Corporation for the two (2) year period
following the Date of Termination and shall be entitled to all of the medical
insurance, pension or other benefits provided by the Corporation as if the
Executive had so remained in the employment of the Corporation. If, for any
reason, whether by law or provisions of the Corporation's employee medical
insurance, pension or other benefit plans, or otherwise any benefits which the
Executive would be entitled to under this SECTION 6 cannot be paid pursuant to
such employee benefit plans, then the Corporation contractually agrees to pay
the Executive the difference between the benefits which the Executive would have
received in accordance with this Section if the relevant employee medical
insurance, pension or other benefit plan could have paid such benefit and the
amount of benefits, if any, actually paid by such employee medical insurance,
pension or other benefit plan. The Corporation shall not be required to fund its
obligation to pay the foregoing difference.

         8. OTHER EMPLOYMENT. In the event of termination under the
circumstances contemplated in SECTION 4(B) hereunder, the Executive shall have
no duty to seek any other employment after termination of his employment with
the Corporation and the Corporation hereby waives and agrees not to raise or use
any defense based upon the position that the Executive had a duty to mitigate or
reduce the amounts due him hereunder by seeking other employment whether
suitable or unsuitable and should the Executive obtain other employment, then
the only effect of such on the obligations of the Corporation shall be that the
Corporation shall be entitled to credit against any payments that would
otherwise be made pursuant to SECTION 7 hereof, any comparable payments to which
the executive is entitled under the employee benefit plans maintained by the
Executive's other employer or employers in connection with services to such
employer or employers after termination of this employment with the Corporation.

         9. STOCK APPRECIATION RIGHTS AND OPTIONS. If the Executive's employment
should terminate under circumstances as to entitle the Executive to receive
payment hereunder, then with respect to any standing Stock Appreciation Rights
and/or Options which did not immediately become exercisable upon the occurrence
of a Change-in-Control, such Stock Appreciation Right or 



                                       8
<PAGE>   9

Option shall be automatically vested and remain outstanding in accordance with
its terms and be exercisable thereafter until the stated expiration date of such
Stock Appreciation Right or Option.

         10.      MISCELLANEOUS.

         (a)      This Agreement shall be construed under the laws of the
                  Commonwealth of Pennsylvania.

         (b)      This Agreement constitutes the entire understanding of the
                  parties hereto with respect to the subject matter hereof and
                  may only be amended or modified by written agreement signed by
                  the parties hereto.

         (c)      The Corporation will require any successor (whether direct or
                  indirect, by purchase, merger, consolidation or otherwise) to
                  all or substantially all of the business and/or assets of the
                  Corporation, by agreement in form and substance satisfactory
                  to the Executive, to expressly assume and agree to perform
                  this Agreement in the same manner required of the Corporation
                  and to perform it as if no such succession had taken place. As
                  used in this Agreement, "Corporation" shall mean the
                  Corporation as hereinbefore defined and any successor to its
                  business and/or assets as aforesaid which executes and
                  delivers the agreement provided for in this subsection (c) or
                  which otherwise becomes bound by all of the terms and
                  provisions of this Agreement by operation of law.

         (d)      This Agreement shall inure to the benefit of and be
                  enforceable by the Executive and the Corporation and their
                  respective legal representatives, executors, administrators,
                  successors, heirs, distributees, devisees and legatees. If the
                  Executive should die while any amounts would still be payable
                  to him hereunder if he had continued to live, all such
                  amounts, unless otherwise provided herein, shall be paid in
                  accordance with the terms of this Agreement to his devisee,
                  legatee or other designee or, if there be no such designee, to
                  his estate.

         (e)      Any notice or other communication provided for in this
                  Agreement shall be in writing and, unless otherwise expressly
                  stated herein, shall be deemed to have been duly given if
                  mailed by United States registered mail, return receipt
                  requested, postage prepaid, addressed in the case of the
                  Executive to his office at the Corporation with a copy to his
                  residence and in the case of the Corporation to its principal
                  executive offices, attention to the Chief Executive Officer.

         (f)      No provision of this Agreement may be modified, waived or
                  discharged unless such waiver, modification or discharge is
                  agreed to in writing signed by the Executive and approved by
                  resolution of the Board of Directors of the Corporation. No
                  waiver by either party hereto at any time of any breach by the
                  other party hereto of, or compliance with, any condition or
                  provision of this Agreement to be performed by such other
                  party shall be deemed a waiver of similar or dissimilar
                  provisions or conditions at the same or at any prior or
                  subsequent time. No agreements or representations, oral or
                  otherwise, express or implied, with respect to the subject
                  matter hereof have been made by either party which are not set
                  forth expressly in this Agreement.

         (g)      The invalidity or unenforceability of any provisions of this
                  Agreement shall not affect the validity or unenforceability of
                  any other provision of this Agreement, which shall remain in

                  invalid or unenforceable, either in whole or in part, this
                  Agreement shall be deemed amended to delete or modify, as

         profitability and growth of the Company through incentives which are
         consistent with the Company's goals and which link the personal
         interests of Employees to those of the Company's stockholders; to
         provide Employees with an incentive for excellence in individual
         performance; and to promote teamwork among Employees. The Plan is

         to share in the success of the Company.

         the right of the Board of Directors to amend or terminate the Plan at
         any time pursuant to ARTICLE 14 hereof, until all Shares subject to it
         shall have been purchased or acquired according to the Plan's
         provisions. However, in no event shall an Award be granted under the

                           acquiring corporation which, immediately following
                           such transaction, holds more than 10% of the
                           consolidated assets of the Company immediately prior

         However, in no event shall a Change in Control be deemed to have
         occurred, with respect to a Employee, if that Employee is part of a
         purchasing group which consummates the Change in Control transaction.
         The Employee shall be deemed "part of a purchasing group" for purposes
         of the preceding sentence if the Employee is an equity participant or
         has agreed to become an equity participant in the purchasing company or
         group (except for (i) passive ownership of less than five percent (5%)
         of the voting equity securities of the purchasing company; or (ii)
         ownership of equity participation in the purchasing company or group
         which is otherwise deemed not to be significant, as determined prior to

2.13     "FAIR MARKET VALUE" shall be the mean between the following prices, as
         applicable, for the date as of which fair market value is to be
         determined as quoted in The Wall Street Journal (or in such other
         reliable publication as the Committee, in its discretion, may determine
         to rely upon): (i) if the Common Stock is listed on the New York Stock
         Exchange, the highest and lowest sales prices per share of the Common
         Stock as quoted in the NYSE Composite Transactions listing for such
         date, (ii) if the Common Stock is not listed on such exchange, the
         highest and lowest sales prices per share of Common Stock for such date
         on (or on any composite index including) the principal united States
         securities exchange registered under the 1934 Act on which the Common
         Stock is listed or (iii) if the Common Stock is not listed on such
         exchange, the highest and lowest sales prices per share of the Common
         Stock for such date on the National Association of Securities Dealers
         Automated Quotations System or any successor system then in use
         ("NASDAQ"). If there are no such sale price quotations for the date as
         of which fair market value is to be determined but there are such sale
         price quotations within a reasonable period both before and after such
         date, then fair market value shall be determined by taking a weighted
         average of the means between the highest and lowest sales prices per
         share of the Common Stock as so quoted on the nearest date before and
         the nearest date after the date as of which fair market value is to be
         determined. The average should be weighted inversely by the respective
         number of trading days between the selling dates and the date as of
         which fair market value is to be determined. If there are no such sale
         prices quotations on or within a reasonable period both before and
         after the date as of which fair market value is to be determined, then
         fair market value of the Common Stock shall be the mean between the
         bona fide bid and asked prices per share of Common Stock as so quoted
         for such date on NASDAQ, or if none, the weighted average of the means
         between such bona fide bid and asked prices on the nearest trading date
         before and the nearest trading date after the date as of which fair
         market value is to be determined, if both such dates are within a
         reasonable period. The average is to be determined in the manner
         described above in this SECTION 2.13. If the fair market value of the
         Common Stock cannot be determined on any basis previously set forth in
         this SECTION 2.13 for the date as of which fair market value is to be
         determined, the Committee shall in good faith determine the fair market
         value of the Common Stock on such date. Fair market value shall be
         determined without regard to any restriction other than a restriction
         which, by its terms, will never lapse.

         considered as owning not only Shares of Stock owned individually but
         also all Shares of stock that are at the time owned, directly or
         indirectly, by or for the spouse, ancestors, lineal descendants and
         bothers and sisters (whether by whole or half blood) of such individual
         and (ii) shall be considered as owning proportionately any Shares
         owned, directly or indirectly, by or for any corporation, partnership,
         estate or trust in which such individual is a stockholder, partner or
         beneficiary.

2.16     "NONQUALIFIED STOCK OPTION" OR "NQSO" means an option to purchase

         discretion), and the Shares are subject to a substantial risk of

         and class of Shares which may be delivered under SECTION 4.1 and in the
         number and class of and/or price of Shares subject to outstanding
         Awards granted under the Plan, and in the number and class of and/or
         price of Shares subject to outstanding Awards granted under the Plan,
         as may be determined to be appropriate and equitable by the Committee,
         in its sole discretion, to prevent dilution or enlargement of rights;
         provided, however, that the number of Shares subject to any Award shall
         always be a whole number.

ARTICLE 5.        ELIGIBILITY AND PARTICIPATION

5.1      ELIGIBILITY. Persons eligible to participate in this Plan shall include
         all Employees of the Company, excluding Officers and Directors.

5.2      ACTUAL PARTICIPATION. Subject to the provisions of the Plan, the
         Committee may, from time to time, select from all eligible Employees
         those to whom Awards shall be granted and shall determine the nature
         and amount of each Award.

ARTICLE 6.        STOCK OPTIONS

6.1      GRANT OF OPTIONS. Subject to the terms and provisions of the Plan, the
         Committee may grant Nonqualified Stock Options in such number, and upon
         such terms, and at any time and from time to time as shall be
         determined by the Committee.

6.2      AWARD AGREEMENT. Each Option shall be evidenced by an Award Agreement
         that shall specify the Option Price, the duration of the Option, the
         number of Shares to which the Option pertains, and such other
         provisions as the Committee shall determine.


                                       5
<PAGE>   6




6.3      OPTION PRICE. The Option Price at which each Option may be exercised
         shall be no less than one hundred percent (100%) of the fair market
         value per share of the Common Stock covered by the Option on the date
         of grant. For purposes of this SECTION 6.3, the fair market value of
         the Common Stock shall be as determined in SECTION 2.14.

6.4      DURATION OF OPTIONS. Each Option granted to an Employee shall expire at
         such time as the Committee shall determine at the time of grant;
         provided, however, that no Option shall be exercisable after the
         expiration of ten years from the date of grant.

6.5      EXERCISE OF OPTIONS. Options granted under this Article 6 shall be
         exercisable at such times and be subject to such restrictions and
         conditions as the Committee shall in each instance approve, which need
         not be the same for each grant or for each Employee.

6.6      PAYMENT. Options granted under this Article 6 shall be exercised by the
         delivery of a written notice of exercise to the Company, setting forth
         the number of Shares with respect to which the Option is to be
         exercised, accompanied by full payment for the Shares.

         The Option Price upon exercise of the Option shall be payable to the
         Company in full either: (a) in cash in United States Dollars (including
         check, bank draft or money order), or (b) by tendering previously
         acquired Shares having an aggregate Fair Market Value at the time of
         exercise equal to the total Option Price, or (c) by a combination of
         (a) and (b).

         The Company will also cooperate with any person exercising an Option
         who participates in a cashless exercise program of a broker or other
         agent under which all or part of the Shares received upon exercise of
         the Option are sold through the broker or other agent or under which
         the broker or other agent makes a loan to such person. Notwithstanding
         the foregoing, unless the Committee, in its discretion, shall otherwise
         determine at the time of grant the exercise of the Option shall not be
         deemed to occur and no Shares of Common Stock will be issued by the
         Company upon exercise of the Option until the Company has received
         payment of the Option Price in full.

6.7      RESTRICTIONS ON SHARE TRANSFERABILITY. The Committee may impose
         restrictions on any Shares acquired pursuant to the exercise of an
         Option granted under this ARTICLE 6 as it may deem advisable,
         including, without limitation, restrictions under applicable Federal
         securities laws, under the requirements of any stock exchange or market
         upon which such Shares are then listed and/or traded, and under any
         blue sky or other state securities laws applicable to such Shares.

6.8      TERMINATION OF EMPLOYMENT. Unless the Committee, in its discretion,
         shall otherwise determine:

         (i) If the employment of an Employee who is not disabled within the
         meaning of Section 422(c)(6) of the Code (a "Disabled Grantee") is
         voluntarily terminated with the consent of the Company or an Employee
         retires under any retirement plan of the Company, any Option held by
         such Employee shall be exercisable by the Employee (but only to the
         extent exercisable by the Employee immediately prior to the termination
         of employment) at any time prior to the expiration date of such Option
         or within one year after the date of termination, whichever is the
         shorter period;

         (ii) If the employment of an Employee who is a Disabled Grantee is
         voluntarily terminated with the consent of the Company, any outstanding
         Option held by such Employee shall be exercisable by the Employee in
         full (whether or not so exercisable by the Employee immediately prior
         to the termination of employment) at any time prior to the expiration
         date of such Option or within one year after the date of termination of
         employment, whichever is the shorter period;



                                       6
<PAGE>   7

         (iii) Following the death of an Employee during employment, any
         outstanding Option held by the Employee at the time of death shall be
         exercisable in full (whether or not so exercisable by the Employee
         immediately prior to the death of the Employee) by the person entitled
         to do so under the Will of the Employee, or, if the Employee shall fail
         to make testamentary disposition of the stock option or shall die
         intestate, by the legal representative of the Employee at any time
         prior to the expiration date of such stock option or within one year
         after the date of death of the Employee, whichever is the shorter
         period;

         (iv) Following the death of an Employee after termination of employment
         during the period when an Option is exercisable, the Option shall be
         exercisable by such person entitled to do so under the Will of the
         Employee by such legal representative (but only to the extent
         exercisable by the Employee immediately prior to the termination of
         employment) at any time prior to the expiration date of such Option or
         within one year after the date of death, whichever is the shorter
         period;

         (v) Unless the exercise period of a stock option following termination
         of employment has been extended as provided in SECTION 13.1, if the
         employment of an Employee terminates for any reason other than
         voluntary termination with the consent of the Company, retirement under
         any retirement plan of the Company or death, all outstanding Options
         held by the Employee at the time of such termination of employment
         shall automatically terminate.

         Whether termination of employment is a voluntary termination with the
         consent of the Company shall be determined, in its discretion, by the
         Committee and any such determination by the Committee shall be final
         and binding.

6.9      NONTRANSFERABILITY OF OPTIONS. No Option granted under the Plan may be
         sold, transferred, pledged, assigned, or otherwise alienated or
         hypothecated, other than by Will or if the Employee dies intestate by
         the laws of descent and distribution of the state of domicile of the
         Employee at the time of death. Further, all Options granted to an
         Employee under the Plan shall be exercisable during his or her lifetime
         only by the Employee.

ARTICLE 7.        STOCK APPRECIATION RIGHTS

7.1      GRANT OF SARS. Subject to the terms and conditions of the Plan, SARs
         may be granted to Employees at any time and from time to time as shall
         be determined by the Committee. The Committee may grant Freestanding
         SARs, Tandem SARs, or any combination of these forms of SARs. The
         Committee shall have complete discretion in determining the number of
         SARs granted to each Employee (subject to ARTICLE 4 herein) and,
         consistent with the provisions of the Plan, in determining the terms
         and conditions pertaining to such SARs. The grant price of a
         Freestanding SAR shall equal the Fair Market Value of a Share on the
         date of grant of the SAR. The grant price of Tandem SARs shall equal
         the Option Price of the related Option, as provided in SECTION 6.3.

7.2      EXERCISE OF TANDEM SARS. Tandem SARs may be exercised for all or part
         of the Shares subject to the related Option upon the surrender of the
         right to exercise the equivalent portion of the related Option. A
         Tandem SAR may be exercised only with respect to the Shares for which
         its related Option is then exercisable.

7.3      EXERCISE OF FREESTANDING SARS. Freestanding SARs may be exercised upon
         whatever terms the Committee, in its sole discretion, imposes upon
         them.

7.4      SAR AGREEMENT. Each SAR grant shall be evidenced by an Award Agreement
         that shall specify the grant price, the term of the SAR, and such other
         provisions as the Committee shall determine.



                                       7
<PAGE>   8

7.5      TERM OF SARs. The term of an SAR granted under the Plan shall be
         determined by the Committee, in its sole discretion; provided however,
         that such term shall not exceed ten (10) years.

7.6      PAYMENT OF SAR AMOUNT. Upon exercise of an SAR, an Employee shall be
         entitled to receive payment from the Company in an amount determined by
         multiplying:

         (a) the difference between the Fair Market Value of a Share on the date
         of exercise over the grant price; by

         (b) the number of Shares with respect to which the SAR is granted.

         At the discretion of the Committee, the payment upon SAR exercise may
         be in cash, in Shares of equivalent value, or in some combination
         thereof.

7.7      RULE 16b-3 REQUIREMENTS. Notwithstanding any other provision of the
         Plan, the Committee may impose such conditions on the exercise of an
         SAR as may be required to satisfy the requirements of Section 16 of the
         Exchange Act (or any successor rule).

7.8      TERMINATION OF EMPLOYMENT. Each SAR Award Agreement shall set forth the
         extent to which the Employee shall have the right to exercise the SAR
         following termination of the Employee's employment with the Company
         and/or its Subsidiaries. Such provisions shall be determined in the
         sole discretion of the Committee, shall be included in the Award
         Agreement entered into with Employees, need not be uniform among all
         SARs issued pursuant to the Plan, and may reflect distinctions based on
         the reasons for termination of such employment.

7.9      NONTRANSFERABILITY OF SARs. No SAR granted under the Plan may be sold,
         transferred, pledged, assigned, or otherwise alienated or hypothecated,
         other than by will or, if the grantee dies intestate, by the laws of
         descent and distribution of the state of domicile of the grantee at the
         time of death. Further, all SARs granted to an Employee under the Plan
         shall be exercisable during his or her lifetime only by such Employee.

ARTICLE 8.        RESTRICTED STOCK

8.1      GRANT OF RESTRICTED STOCK. Subject to the terms and provisions of the
         Plan, the Committee, at any time and from time to time, may grant
         Shares of Restricted Stock to Employees in such amounts as the
         Committee shall determine.

8.2      RESTRICTED STOCK AGREEMENT. Each Restricted Stock grant shall be
         evidenced by a Restricted Stock Award Agreement that shall specify the
         Period(s) of Restriction, the number of Shares of Restricted Stock
         granted, and such other provisions as the Committee shall determine.

8.3      TRANSFERABILITY. Except as provided in this ARTICLE 8, the Shares of
         Restricted Stock granted herein may not be sold, transferred, pledged,
         assigned or otherwise alienated or hypothecated until the end of the
         applicable Period of Restriction established by the Committee and
         specified in the Restricted Stock Award Agreement, or upon earlier
         satisfaction of any other conditions, as specified by the Committee in
         its sole discretion and set forth in the Restricted Stock Award
         Agreement. All rights with respect to the Restricted Stock granted to
         an Employee under the Plan shall be available during his or her
         lifetime only to such Employee.

8.4      OTHER RESTRICTIONS. Subject to ARTICLE 10 herein, the Committee shall
         impose such other conditions and/or restrictions on any Shares of
         Restricted Stock granted pursuant to the Plan as it may deem 


                                       8
<PAGE>   9


         advisable including, without limitation, a requirement that Employees
         pay a stipulated purchase price for each Share of Restricted Stock,
         restrictions based upon the achievement of specific performance goals
         (Company-wide, divisional, and/or individual), time-based restrictions
         on vesting following the attainment of the performance goals, and/or
         restrictions under applicable Federal or state securities laws. The
         Company shall retain the certificates representing Shares of Restricted
         Stock in the Company's possession until such time as all conditions
         and/or restrictions applicable to such Shares have been satisfied.
         Except as otherwise provided in this ARTICLE 8, Shares of Restricted
         Stock covered by each Restricted Stock grant made under the Plan shall
         become freely transferable by the Employee after the last day of the
         applicable Period of Restriction.

8.5      VOTING RIGHTS. During the Period of Restriction, Employees holding
         Shares of Restricted Stock granted hereunder may exercise full voting
         rights with respect to those Shares.

8.6      DIVIDENDS AND OTHER DISTRIBUTIONS. During the Period of Restriction,
         Employees holding Shares of Restricted Stock granted hereunder may be
         credited with regular cash dividends paid with respect to the
         underlying Shares while they are so held. The Committee may apply any
         restrictions to the dividends that the Committee deems appropriate. In
         the event that any dividend constitutes a "derivative security" or an
         "equity security" pursuant to Rule 16(a) under the Exchange Act, such
         dividend shall be subject to a vesting period equal to the remaining
         vesting period of the Shares of Restricted Stock with respect to which
         the dividend is paid.

8.7      TERMINATION OF EMPLOYMENT. Each Restricted Stock Award Agreement shall
         set forth the extent to which the Employee shall have the right to
         receive unvested Restricted Shares following termination of the
         Employee's employment with the Company. Such provisions shall be
         determined in the sole discretion of the Committee, shall be included
         in the Award Agreement entered into with each Employee, need not be
         uniform among all Shares of Restricted Stock issued pursuant to the
         Plan, and may reflect distinctions based upon the reasons for
         termination of such employment.


ARTICLE 9.        PERFORMANCE UNITS AND PERFORMANCE SHARES

9.1      GRANT OF PERFORMANCE UNITS/SHARES. Subject to the terms of the Plan,
         Performance Units and/or Performance Shares may be granted to Employees
         in such amounts and upon such terms, and at any time and from time to
         time, as shall be determined by the Committee.

9.2      VALUE OF PERFORMANCE UNITS/SHARES. Each Performance Unit shall have an
         initial value that is established by the Committee at the time of
         grant. Each Performance Share shall have an initial value equal to the
         Fair Market Value of a Share on the date of grant. The Committee shall
         set performance goals in its discretion which, depending upon the
         extent to which they are met, will determine the number and/or value of
         Performance Units/Shares that will be paid out to the Employee. For
         purposes of this ARTICLE 9, the time period during which the
         performance goals must be met shall be called a "Performance Period."

9.3      EARNING OF PERFORMANCE UNITS/SHARES. Subject to the terms of this Plan,
         after the applicable Performance Period has ended, the holder of
         Performance Units/Shares shall be entitled to receive payout on the
         number and value of Performance Units/Shares earned by the Employee
         over the Performance Period, to be determined as a function of the
         extent to which the corresponding performance goals have been achieved.

9.4      FORM AND TIMING OF PERFORMANCE UNITS/SHARES. Payment of earned
         Performance Units/Shares shall be made in a single lump sum within
         seventy-five (75) calendar days following the close of the applicable
         Performance Period. Subject to the terms of this Plan, the Committee,
         in its sole discretion, may pay 


                                       9
<PAGE>   10


         earned Performance Units/Shares in the form of cash or Shares (or a
         combination thereof) which have an aggregate Fair Market Value equal to
         the value of the earned Performance Units/Shares at the close of the
         applicable Performance Period. Such Shares may be granted subject to
         any restrictions deemed appropriate by the Committee.

         At the discretion of the Committee, Employees may be entitled to
         receive any dividends declared with respect to Shares which have been
         earned in connection with grants of Performance Units and/or
         Performance Shares which have been earned, but not yet distributed to
         Employees (such dividends shall be subject to the same accrual,
         forfeiture, and payout restrictions as apply to dividends earned with
         respect to Shares of Restricted Stock, as set forth in SECTION 8.6
         herein). In addition, Employees may, at the discretion of the
         Committee, be entitled to exercise their voting rights with respect to
         such Shares.

9.5      TERMINATION OF EMPLOYMENT DUE TO DEATH, DISABILITY OR RETIREMENT.
         Unless otherwise determined by the Committee and set forth in the
         Employee's Award Agreement, in the event the employment of an Employee
         is terminated by reason of death, disability or Retirement during a
         Performance Period, the Employee shall receive a payout of the
         Performance Units/Shares which is prorated, as specified by the
         Committee in its discretion. Payment of earned Performance Units/Shares
         shall be made at a time specified by the Committee in its sole
         discretion and set forth in the Employee's Award Agreement.

9.6      TERMINATION OF EMPLOYMENT FOR OTHER REASONS. In the event that an
         Employee's employment terminates for any reason other than those
         reasons set forth in SECTION 9.5 herein, all Performance Units/Shares
         shall be forfeited by the Employee to the Company unless determined
         otherwise by the Committee, as set forth in the Employee's Award
         Agreement.

9.7      NONTRANSFERABILITY. Performance Units/Shares may not be sold,
         transferred, pledged, assigned or otherwise alienated or hypothecated,
         other than by will or if the grantee dies intestate by the laws of
         descent and distribution of the state of domicile of the grantee at the
         time of death. Further, an Employee's rights under the Plan shall be
         exercisable during the Employee's lifetime only by the Employee or the
         Employee's legal representative.


ARTICLE 10.       BENEFICIARY DESIGNATION

Each Employee under the Plan may, from time to time, name any beneficiary or
beneficiaries (who may be named contingently or successively) to whom any
benefit under the Plan is to be paid in case of his or her death before he or
she receives any or all of such benefit. Each such designation shall revoke all
prior designations by the same Employee, shall be in a form prescribed by the
Company, and will be effective only when filed by the Employee in writing with
the Company during the Employee's lifetime. In the absence of any such
designation, benefits remaining unpaid at the Employee's death shall be paid to
the Employee's estate.

ARTICLE 11.       DEFERRALS

The Committee may permit or require an Employee to defer such Employee's receipt
of the payment of cash or the delivery of Shares that would otherwise be due to
such Employee by virtue of the exercise of an Option or SAR, the lapse or waiver
of restrictions with respect to Restricted Stock, or the satisfaction of any
requirements or goals with respect to Performance Units/Shares. If any such
deferral election is required or permitted, the Committee shall, in its sole
discretion, establish rules and procedures for such payment deferrals.

12.1     EMPLOYMENT. Nothing in the Plan shall interfere with or limit in any
         way the right of the Company to terminate any Employee's employment at
         any time, nor confer upon any Employee any right to continue in the
         employ of the Company.

12.2     PARTICIPATION. No Employee shall be entitled to have the right to be

         Control, unless otherwise specifically prohibited under applicable
         laws, or by the rules and regulations of any governing governmental
         agencies or national securities exchanges:

         (a) Any and all Options and SARs granted hereunder shall become

         shall be deemed to have been fully earned for the entire Performance
         Period(s) as of the effective date of the Change in Control. The
         vesting of all Awards denominated in Shares shall be accelerated as of
         the effective date of the Change in Control, and there shall be paid
         out in cash to Employees within thirty (30) days following the
         effective date of the Change in Control an amount equal to one hundred
         percent (100%) of all targeted cash payout opportunities associated
         with outstanding cash-based Awards; and

         (d) Subject to ARTICLE 14 herein, the Committee shall have the

         to accelerate the vesting of any Award granted under the Plan to any
         Employee, including without limitation acceleration to such a date that
         would result in said Awards becoming immediately vested.

13.3     TERMINATION, AMENDMENT AND MODIFICATIONS OF CHANGE IN CONTROL
         PROVISIONS. Notwithstanding any other provision of this Plan or any
         Award Agreement provision, the provisions of this ARTICLE 13 may not be
         terminated, amended or modified on or after the date of a Change in
         Control to affect adversely any Award theretofore granted under the
         plan without the prior written consent of the Employee with respect to
         said Employee's outstanding Awards; provided, however, the Board of
         Directors, upon recommendation of the committee, may terminate, amend,
         or modify this ARTICLE 13 at any time and from time to time prior to
         the date of a Change in Control.

ARTICLE 14.       AMENDMENT, MODIFICATION AND TERMINATION

14.1     ADMENDMENT, MODIFICATION AND TERMINATION. The Board may at any time and
         from time to time, alter, amend, suspend, or terminate the Plan in
         whole or in part.

14.2     ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR
         NONRECURRING EVENTS. The Committee may make adjustments in the terms
         and conditions of, and the criteria included in, Awards in recognition
         of unusual or nonrecurring events (including, without limitation, the
         events described in SECTION 4.3 hereof) affecting the Company or the
         financial statements of the Company or of changes in 


                                       11
<PAGE>   12


         applicable laws, regulations, or accounting principles, whenever the
         Committee determined that such adjustments are appropriate in order to
         prevent dilution or enlargement of the benefits or potential benefits
         intended to be made available under the Plan; provided that no such
         adjustment shall be authorized to the extent that such authority would
         be inconsistent with the Plan's meeting the requirements of Section
         162(m) of the Code, as from time to time amended.

14.3     AWARDS PREVIOUSLY GRANTED. No termination, amendment, or modification
         of the Plan shall adversely affect in any material way any Award
         previously granted under the Plan, without the written consent of the
         Employee holding such Award.

14.4     COMPLIANCE WITH CODE 162(m). At all times when Code Section 162(m) is
         applicable, all Awards granted under this Plan shall comply with the
         requirements of Code Section 162(m); provided, however, that in the
         event the Committee determines that such compliance is not desired with
         respect to any Award or Awards available for grant under the Plan, then
         compliance with Code Section 162(m) will not be required. In addition,
         in the event that any changes are made to Code Section 162(m) to permit
         greater flexibility with respect to any Award or Awards available under
         the Plan, the Committee may, subject to this ARTICLE 14, make any
         adjustments it deems appropriate.

ARTICLE 15.       WITHHOLDING

15.1     TAX WITHHOLDING. The Company shall have the power and the right to
         deduct or withhold, or require any Employee to remit to the Company, an
         amount sufficient to satisfy Federal, state and local taxes, domestic
         or foreign, required by law or regulation to be withheld with respect
         to any taxable event arising as a result of this Plan.

15.2     SHARE WITHHOLDING. With respect to withholding required upon the
         exercise of Options or SARs, upon the lapse of restrictions on
         Restricted Stock, or upon any other taxable event arising as a result
         of Awards granted hereunder, Employees may elect, subject to the
         approval of the Committee, to satisfy the withholding requirement, in
         whole or in part, by having the Company withhold Shares having a Fair
         Market Value on the date the tax is to be determined equal to the
         minimum statutory total tax which could be imposed on the action. All
         such elections shall be irrevocable, made in writing, signed by the
         Employee, and shall be subject to any restrictions or limitations that
         the Committee, in its sole discretion, may determine.

ARTICLE 16.       INDEMNIFICATION

Each person who is or shall have been a member of the Committee, or of the
Board, shall be indemnified and held harmless by the Company against and from
any loss, cost, liability or expense that may be imposed upn or reasonably
incurred by him or her in connection with or resulting from any claim, action,
suit or proceeding to which he or she may be a party or in which he or she may
be involved by reason of any action taken or failure to act under the Plan and
against and from any and all amounts paid by him or her in settlement thereof,
with the Company's approval, or paid by him or her in satisfaction of any
judgment in any such action, suit or proceeding against him or her, provided he
or she shall give the Company an opportunity at its own expense, to handle and
defend the same before he or she undertakes to handle and defend it on his or
her own behalf. The foregoing right of indemnification shall not be exclusive of
any other right of indemnification to which such persons may be entitled under
the Company's Articles of Incorporation or Bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold them
harmless.

ARTICLE 17.       SUCCESSOR

All obligations of the Company under the Plan with respect to Awards granted
hereunder shall be binding upon any successor to the Company, whether the
existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business
and/or assets of the Company.

ARTICLE 18.       LEGAL CONSTRUCTION

18.1     GENDER AND NUMBER. Except where otherwise indicated by the context, any
         masculine term used herein shall also include the feminine; the plural
         shall include the singular and the singular shall include the plural.

18.2     SEVERABILITY. In the event any provision of the Plan shall be held
         illegal or invalid for any reason, the illegality or invalidity shall
         not affect the remaining parts of the Plan, and the Plan shall be
         construed and enforced as if the illegal or invalid provision had not
         been included.

18.3     REQUIREMENTS OF LAW. The granting of Awards and the issuance of Shares
         under the Plan shall be subject to all applicable laws, rules, and
         regulations, and to such approvals by governmental agencies or national
         securities exchanges as may be required.

18.4     SECURITIES LAW COMPLIANCE. With respect to (i) any person who is
         required to file reports pursuant to the rules promulgated under
         Section 16 of the Exchange Act and (ii) insiders, transactions under
         this Plan are intended to comply with all applicable conditions of Rule
         16b-3 or its successors under the Exchange Act. To the extent any
         provision of the Plan or action by the Committee fails to so comply, it
         will be deemed null and void to the extent permitted by law and deemed
         advisable by the Committee.

18.5     GOVERNING LAW. To the extent not preempted by Federal law, the Plan and
         all agreements hereunder, shall be construed in accordance with and
         governed by the laws of the Commonwealth of Pennsylvania.

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


The following discussion should be read in conjunction with the "Selected
Consolidated Financial Statements" and notes thereto appearing elsewhere in this
Annual Report to Shareholders.

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

The statements contained in this Annual Report to Shareholders, specifically
those contained in the following Management's Discussion and Analysis of Results
of Operations and Financial Condition which are not historical, are
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. These forward-looking statements represent Tollgrade Communications,
Inc.'s (the "Company") present expectations or beliefs concerning future events.
The Company cautions that such statements must be qualified by important factors
that could cause actual earnings and other results to differ materially from
those achieved in the past or those expected by the Company. These include rapid
technological change, along with the need to continually develop new products;
the Company's dependence on a single product line; competition; the Company's
dependence on key employees; difficulties in managing the Company's growth; the
Company's dependence upon a small number of large customers and certain
suppliers; the Company's dependence upon proprietary rights; risks of
third-party claims of infringement; and government regulation.

OVERVIEW
The Company was organized in 1986 and began operations in 1988. The Company
designs, engineers, markets and supports test access and test extension products
for the telecommunications and cable television industries. The Company's
telecommunication proprietary 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 90% of the Company's revenue for the year
ended December 31, 1998 and will continue to account for a majority of the
Company's revenues for the foreseeable future. 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's telecommunication product sales are primarily to the five
Regional Bell Operating Companies (RBOCs) as well as major independent telephone
companies such as Sprint and to certain digital loop carrier (DLC) equipment
manufacturers. For the year ended December 31, 1998, approximately 79% of the
Company's total revenue was generated from sales to these five RBOCs, the two
largest of which comprised approximately 54% of revenues. The Company intends to
market and sell its cable products directly, as well as through various Original
Equipment Manufacturer (OEM) arrangements with cable network equipment
manufacturers. The Company presently has one OEM arrangement under contract and
works on less formal arrangements with several other OEM partners. Sales for the
Company's cable products for the year ended December 31, 1998 were not material.

      The Company's operating results have fluctuated and may continue to
fluctuate as a result of various factors, including the timing of orders from
and shipments to the RBOCs.

                                                                               7


<PAGE>   3



This timing is particularly sensitive to various business factors within each of
the RBOCs, including the RBOCs relationships with their various organized labor
groups. During the third quarter of 1998, the Company's financial results were
impacted by the effect of certain labor disputes at Bell Atlantic, USWest and
Southern New England Telephone. These work stoppages, along with other factors,
disrupted ongoing and established network expansion and maintenance programs and
exacerbated seasonally lower sales. Certain contracts concerning the RBOCs
organized employees were renegotiated during the third quarter of 1998. Refer to
discussions on 1998 revenues for further comments.

     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, the Company has recently experienced certain customer demands to
consolidate product purchases which have translated into large bulk orders.
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 pertaining to these large orders.
Additionally, recent consolidations and potential future consolidations among
the RBOCs, and their ability to consolidate their inventory and product
procurement systems could cause fluctuations or delays in the Company's order
patterns. The Company cannot predict such future events or business conditions,
and the Company's results may be adversely affected by these industry trends in
the primary markets its serves.

     Although international sales to date have not been significant, the Company
believes the international markets offer opportunities. 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. Certain competitive elements also are found
internationally which do not exist in the Company's domestic markets. The
Company has, up to the present time, utilized the professional services of
various marketing consultants to define the Company's international market
opportunities. Markets that are the subject of continuing review are those
markets in China, Europe and several countries in the Pacific Rim area. During
the fourth quarter of 1998, the Company streamlined the structure responsible
for its international efforts. The changes resulted in a more cost-effective
structure that is now focused at the customer level. There continues to be a
high level of interest expressed by certain potential customers in the
international markets; however, there can be no assurance that these efforts
will be successful or that the Company will achieve significant international
sales.

     The Company believes that continued growth will depend 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 percent of
revenues were approximately 14.9% for the year ended December 31, 1998. The
Company expects its research and development expenses to continue at significant
levels.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

REVENUES
Revenues for the year ended December 31, 1998 were $46.3 million and were $0.9
million, or 1.9%, higher than the revenues of $45.4 million for the year ended
December 31, 1997. Revenues for both periods consisted almost entirely of
product sales. Revenues for 1998 and 1997 include approximately $0.5 million and
$0.9 million, respectively, for non-recurring engineering fees, royalty and
license fees. The increase in revenues is primarily associated with new product
revenues. During 1998, the Company generated revenues of approximately $2.2
million associated with new product introductions, including the Company's
LIGHTHOUSE cable products, while same product sales between periods decreased
$1.3 million, or 3.0%. This decrease occurred primarily in the second half of
1998, and the Company believes it was caused by several factors, including
certain labor disputes at Bell Atlantic, USWest and Southern New England
Telephone during the third quarter of 1998, higher than expected inventories at
Ameritech, as well as slower than expected deployment of MCU products within
certain regions of Bell Atlantic. Bell Atlantic's testability improvement
initiatives migrated to more complex embedded DLC

architectures that require the provisioning of additional equipment and
increased installation time. The Company is working to implement strategies
designed to return product usage to historical levels for certain customers
through comprehensive technical training and other testability improvement
initiatives. The effectiveness of these programs from a timing point of view are
highly dependent upon a number of factors outside of the Company's control,
including the Company's customers' willingness to dedicate the appropriate
levels of resources to see such initiatives through to their successful
conclusion. Therefore, there can be no assurances as to the ultimate
effectiveness of these programs in returning product deployment to historical
levels. 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, and are not necessarily indicative of long-term trends in
sales of the Company's products. Management believes that there is a continuing
possibility that the requirements for certain important MCU products which are
utilized in legacy DLC systems may be satisfied in the near future, especially
within one major customer. In order to reduce associated risks, the Company is
focusing on the development of new product lines to attempt to meet the other
requirements of this and other customers.

GROSS PROFIT
Gross profit for 1998 was $26.7 million compared to $25.3 million for 1997,
representing an increase of $1.4 million, or 5.3%. Gross profit as a percentage
of revenues increased to 57.6% for 1998 compared to 55.7% for 1997. The overall
increase in gross profit resulted primarily from the increased sales levels,
while improvements in gross margin as a percentage of sales were a result of
increased sales volumes and increased manufacturing efficiencies. The Company's
continuing gross margin levels will depend on its success in holding pricing,
gaining further cost reductions, as well as the mix of products sold including
the effect of the Company's cable products which carry lower gross margins than
earned historically on the Company's telecommunication products.

SELLING AND MARKETING EXPENSE
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 marketing programs. Selling and marketing expense for 1998
was $5.7 million, or 12.3% of revenues, compared to $5.4 million, or 12.0% of
revenues for 1997. This increase of $0.3 million, or 4.7%, is primarily
associated with additional personnel to support expanding product lines and
increased consulting and travel expenses associated with international market
development. The Company expects selling and marketing expenses to rise
commensurate with increased revenues and selling efforts. The Company is
continuing its efforts to expand its business by marketing new products and the
development of comprehensive technical training and other testability
improvement initiatives.

GENERAL AND ADMINISTRATIVE EXPENSE
General and administrative expenses consist primarily of personnel costs for
finance, administrative and general management personnel as well as accounting
and legal expenses. General and administrative expense for 1998 was $4.1
million, or 8.9% of revenues, compared to $3.8 million, or 8.3% of revenues for
1997. This increase of $0.3 million, or 9.5%, is primarily attributable to
increased expenditures for legal and professional fees associated with business
development activities as well as personnel recruiting costs.

RESEARCH AND DEVELOPMENT EXPENSE
Research and development expenses consist primarily of personnel costs and costs
associated with the development of new products and technologies. Research and
development expense for 1998 was $6.9 million, or 14.9% of revenues, compared to
$5.9 million, or 13.1% of revenues for 1997. This increase of $1.0 million, or
15.7%, was principally due to costs associated with new product development and
the addition of personnel to support these new product development activities.
The Company expenses all research and development costs as they are incurred.

OTHER INCOME AND EXPENSE
Other income, which consists primarily of interest income, was $1.1 million for
1998 compared to $0.9 million for 1997. The increase of $0.2 million, or 18.2%,
includes approximately $0.2 million of net key man life insurance proceeds
associated with the death of the Company's former Chairman R. Craig Allison.
Additionally, 1998 other income and expense included

                                                                               9


<PAGE>   5



interest expense of approximately $0.1 million related to settlements of issues
with certain prior years' tax returns.

PROVISION FOR INCOME TAXES
The Company's effective tax rate for 1998 was 36.7% of income before income
taxes, compared to the 37.7% rate in 1997. The decrease in the effective income
tax rate primarily reflects the permanent effect of an increase in non-taxable
interest income on the Company's short- and long-term investments related to
individual municipal bonds.

NET INCOME AND EARNINGS PER SHARE
For the year ended December 31, 1998, net income was $7.0 million compared to
$6.9 million for the year ended December 31, 1997, representing an increase of
$0.1 million, or 1.2%. Diluted earnings per common share of $1.17 for 1998
increased by 1.7%, or $.02, from the $1.15 earned in 1997. Fiscal year 1998
includes approximately $0.2 million, or $.04 per share, related to the after-tax
effect of net key man life insurance as previously discussed above. Excluding
the effect of net key man life insurance proceeds, net income decreased $0.1
million, or 2.1% while diluted earnings per share for 1998 decreased 1.7% to
$1.13 per share. Diluted weighted average shares of common stock and equivalents
outstanding were 5,966,551 in 1998 compared to 5,961,540 in 1997. As a
percentage of revenues, net income for 1998 decreased to 15.1% from 15.2% in
1997.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

REVENUES
Revenues for the year ended December 31, 1997 were $45.4 million and were $7.9
million, or 21.2% higher than revenues of $37.5 million for the year ended
December 31, 1996. Revenues for both periods consisted almost entirely of
product sales. 1997 revenues included $250,000 of royalty and license fees,
while similar fees for 1996 were immaterial. The increase in revenues was
primarily associated with the increase in unit volume sales of the MCU product
line as a result of increased market penetration and customer acceptance. The
increase included revenues of $0.7 million from six new products introduced in
1997. Overall, increased product demand was at least partly attributable to
technology licensing agreements and/or joint venture relationships with certain
major DLC vendors, as well as continued expansion of a marketing program to
train customers in advanced line test system trouble-shooting. 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, and
are not necessarily indicative of long-term trends in sales of the Company's
products. Management believed that during fiscal year 1998, there was a
possibility that one of the Company's major customers would satisfy a
substantial portion of its requirements for certain of the Company's important
product lines. Management focused on the development of new product lines to
attempt to meet the other requirements of this and other customers. Refer to
discussions on 1998 revenues for further comments

GROSS PROFIT
Gross profit for 1997 was $25.3 million compared to $19.2 million for 1996,
representing an increase of $6.1 million, or 32.1%. Gross profit as a percentage
of revenues increased to 55.7% for 1997 compared to 51.1% for 1996. The overall
increase in gross profit margin resulted primarily from the increased sales
levels, while improvements in gross margin as a percentage of sales were a
result of increased sales volumes and increased manufacturing efficiencies. The
Company's ability to sustain current gross margin levels has depended on its
success in gaining further cost reductions, as well as experiencing a similar
mix of products sold and maintaining current pricing levels.

SELLING AND MARKETING EXPENSE
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 marketing programs. Selling and marketing expense for 1997
was $5.4 million, or 12.0% of revenues, compared to $4.8 million, or 12.7% of
revenues for 1996. This increase of $0.6 million, or 14.2%, reflected additional
salaries and benefits associated with increased staffing levels to support
expanding product lines and increased consulting and travel expenses associated
with the planned expansion into international markets. The Company's selling and
marketing expenses have risen commensurate with increased revenues and selling
efforts. The Company is continuing its efforts to expand its business

10


<PAGE>   6


by marketing new products, developing additional customer training programs and
expanding its international presence.

GENERAL AND ADMINISTRATIVE EXPENSE
General and administrative expenses consist primarily of personnel costs for
finance, administrative and general management personnel, as well as accounting
and legal expenses. General and administrative expense for 1997 was $3.8
million, or 8.3% of revenues, compared to $2.6 million, or 6.8% of revenues for
1996. This increase of $1.2 million, or 47.6%, was primarily attributable to
additional salaries and benefits associated with increased staffing levels to
support the expanded business operations and increased travel and business
development activities.

RESEARCH AND DEVELOPMENT EXPENSE
Research and development expenses consist primarily of personnel costs and costs
associated with the development of new products. Research and development
expense for 1997 was $5.9 million, an increase of $2.0 million, or 51.6%,
compared to $3.9 million for 1996. The increase was principally due to costs
associated with additional personnel to support new product introductions. As a
percentage of revenues, research and development expense was 13.1% for 1997
compared to 10.5% for 1996. The Company expenses all research and development
costs as they are incurred.

OTHER INCOME AND EXPENSE
Other income, which consists primarily of interest income, was $0.9 million for
1997 compared to $0.8 million for 1996. The increase in other income was
primarily attributable to increased interest income, which resulted from the
increased levels of investable funds.

PROVISION FOR INCOME TAXES
The Company's effective tax rate for 1997 was 37.7% of income before income
taxes, compared to the 36.2% rate in 1996. The slight increase reflected
increases in state taxes offset by benefits from higher levels of tax-exempt
interest and increased credits for research and development.

LIQUIDITY AND CAPITAL RESOURCES
The Company had working capital of $40.5 million as of December 31, 1998
compared to the working capital of $34.6 million as of December 31, 1997. The
increase of $5.9 million, or 17.3%, can be attributed to operating cash flow
(income from operations before depreciation and amortization) and proceeds from
the exercise of stock options exceeding requirements for purchases of property
and equipment and funding of the Company's stock buyback program. Significant
components of the Company's change in working capital include an increase in
cash and cash equivalents, which include the effect of cash received as a result
of stock option exercises and net collections, an increase in inventories due to
the investment required to introduce new products and to maintain sufficient
inventory stocking levels. Most significantly offsetting these increases was a
decrease in short-term investments of $1.4 million; the majority of such funds
were invested in long-term investments and, as such, are still available for
general corporate use upon maturity. These investments reflect the Company's
strategy to migrate to individual municipal bonds with a maturity of more than
one year and less than eighteen months and was undertaken to maximize investment
income levels. As of December 31, 1998, the Company had $24.1 million of cash
and cash equivalents, short-term and long-term investments which are available
for acquisitions and other corporate requirements.

     The Company made capital expenditures of $1.7 million in 1998 and were
primarily related to an upgrade of the MIS infrastructure, production test
equipment and fixtures, as well as leasehold improvements made to the Company's
facilities. Capital expenditures were $1.2 million and $2.0 million for 1997 and
1996, respectively, and were primarily related to office equipment, test
fixtures and development systems, tooling and leasehold improvements. The
Company presently has no material capital expenditure commitments. Planned
capital expenditures for 1999 are anticipated to total approximately $2.4
million. These planned capital projects include test fixtures and development
systems, computer and office equipment and leasehold improvements to the
Company's facilities.

     As of May 31, 1998, the Company terminated its $2,500,000 bank line of
credit. The Company believes that, based upon its current financial position,
the line of credit is not necessary to be continued at the present time.

     On April 22, 1997, the Company's Board of Directors authorized a program to
purchase up to 200,000 shares of its common stock over the

                                                                              11

next two years. The shares will be utilized to provide stock under certain
employee benefit programs. The number of shares that the Company intends to
purchase and the time of such purchases will be determined by the Company, at
its discretion. The Company plans to use existing cash and short-term
investments to finance the purchases. As of December 31, 1998, the Company had
purchased 106,900 shares of common stock under this program. Subsequent to
December 31, 1998 and through March 1, 1999, the Company purchased an additional
27,900 shares of common stock under this program.

     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
1998 results. The Company's financial position enables it to meet cash
requirements for operations and capital expansion programs.

     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 rights will be exercisable only if a person or group
acquires or announces a tender or exchange offer for 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.

     If after a person or group acquires 20% or more of the outstanding common
stock, 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%.

     The rights were not distributed in response to any specific effort to
acquire control of the Company, nor is the Company presently aware of any such
effort. The distribution of the rights will not affect the Company's reported
earnings and is not taxable to shareholders or to the Company. Shareholders will
not receive any documents evidencing their rights unless and until the rights
become exercisable. Until that time, the rights will not trade separately from
the common stock. The rights will expire on August 15, 2006.

IMPACT OF THE YEAR 2000 ISSUE
The Year 2000 issue exists because many computer systems and applications use
two-digit rather than four-digit date fields to designate an applicable year. As
a result, the systems and applications may not properly recognize the year 2000
or process data which include it, potentially causing data miscalculations or
inaccuracies or operational malfunctions or failures.

     The Company has established a Year 2000 committee to transition the
Company's business applications, computing infrastructure and communication
systems into the next millennium. The objectives of the Year 2000 committee are
to ensure all internal computer systems function correctly in the Year 2000,
ensure data exchanged with external organizations conforms to Year 2000
standards and ensure all products sold by the Company conform to Year 2000
standards. The Company has developed an inventory of all Company business
systems and corresponding software applications and is currently in the process
of assessing the business priority of each system. Each system will be
classified by mission criticality and a determination will be made to either
replace or remediate the system, depending upon its importance. In addition, the
Year 2000 project will include a review of the Year 2000 compliance efforts of
the Company's key suppliers and other principal business partners and, as
appropriate, the development of joint business support and continuity plans


12


<PAGE>   8



for Year 2000 issues. While this initiative is broad in scope, it has been
structured to identify and prioritize efforts for mission-critical systems,
products and key business partners.

     The inventory and assessment phases have been substantially completed as of
December 31, 1998. The Company has established a Year 2000 test center to
certify all business applications and processes utilized throughout the Company.
To date, more than 300 internal software applications or systems have been
identified for testing. Initial results indicate less than 20% of these
applications do not meet Year 2000 standards and, more importantly, less than 5%
are business-critical. During the remainder of 1999, the Year 2000 committee
will focus attention to remediation and testing of internal business systems and
contingency planning.

     The Company's products with time-of-day (TOD) clocks in their design have
been tested for successful Year 2000 operation. Products that do not have TOD
clocks have no potential Year 2000 operational issues and, therefore, have not
been tested. The Company believes that it will have no material exposure to
contingencies related to the Year 2000 issue for the products it has sold.

     In order to ensure Year 2000 compliance among the Company's key suppliers
and business partners, the Year 2000 committee developed surveys that were
provided to the suppliers in addition to verifying compliance efforts via the
suppliers' and business partners' Web sites for Year 2000 compliance-related
information. The Company is currently examining where and how outside suppliers
and business partners impact the business and apply the same mission-critical
standard to suppliers and business partners that applies to the Company's own
internal systems.

     Under the Company's current Year 2000 plan, the target date of June 30,
1999 has been established for completion of remediation, testing and
implementation. The Company's ability to meet that target date is dependent upon
the timely provision of necessary upgrades and modifications by the Company's
suppliers and customers. There can be no guarantee that the systems of other
companies on which the Company's systems rely will be timely converted, or that
a failure to convert by another company, or a conversion that is incompatible
with the Company's systems, would not have a material adverse effect on the
Company.

     The Company currently estimates the expenses associated with the
anticipated Year 2000 efforts to be approximately $0.1 million through 1999,
with an additional $0.3 million for capital improvement costs to support this
project. The costs expensed to date have been immaterial. The timing of the
Company's expenses may vary and is not necessarily indicative of readiness
efforts or progress to date. The Company anticipates that a portion of the Year
2000 expenses will not be incremental costs, but rather will represent the
redeployment of existing Information Technology (IT) resources.

     As part of the Year 2000 initiative, the Company is evaluating scenarios
that may occur as a result of the century change and is in the process of
developing contingency and business plans that address potential Year
2000-related occurrences. These plans are expected to assess the potential for
business disruption and to provide operational back-up, recovery and restoration
alternatives.

     The above information is based on the Company's current best estimates.
Given the complexity of the Year 2000 issues and risks, actual results may vary
materially from those anticipated and discussed above. Specific factors that
might cause such differences include, among others, the availability and cost of
personnel trained in this area, the ability to locate and correct all affected
computer systems, applications and products and the timing and success of
remedial efforts of the Company's third party suppliers and business partners.

BACKLOG
The Company's backlog consists of firm customer purchase orders for the
Company's various products. As of December 31, 1998, the Company had a backlog
of $0.6 million, a $1.0 million decrease from the December 31, 1997 backlog of
$1.6 million. At December 31, 1998, the composition of the backlog related
primarily to one customer order, while backlog at December 31, 1997 consisted of
several customer orders. 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, and are not necessarily indicative of
long-term trends in sales of the Company's products.


                                                                              13

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 judgements. Financial information elsewhere in
this Annual Report is consistent with that in the financial statements.

     Management has established and maintains a system of internal control
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 control 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 Accountants. As part of their audit of the Company's 1998 financial
statements, PricewaterhouseCoopers LLP considered the Company's system of
internal control to the extent they deemed necessary to determine the nature,
timing and extent of their audit tests. The Independent Accountants' Report
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
Public Accountants and management. The Independent Public Accountants 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 ACCOUNTANTS


January 25, 1999

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, of changes in shareholders' equity and of
cash flows present fairly, in all material respects, the consolidated financial
position of Tollgrade Communications, Inc. and subsidiaries at December 31, 1998
and 1997, and the consolidated results of their operations and their cash flows
for each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles. 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 generally accepted auditing
standards 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 the opinion expressed above.

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

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BASIS OF PRESENTATION
Tollgrade Communications, Inc. (the Company) designs, engineers, markets and
supports test access and test extension products for the telecommunications and
cable television industries. The Company's telecommunications proprietary
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 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 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 insured by the Federal Deposit Insurance
Corporation.

INVESTMENTS
Short-term investments at December 31, 1997 and 1998 consist of a treasury note
and/or 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 individual municipal bonds
with a maturity of more than one year but less than eighteen months. The primary
investment purposes are to provide a reserve for future business purposes,
including possible acquisitions, capital expenditures and to meet working
capital requirements.

     The Company classifies its investment in all debt securities as "held to
maturity" in accordance with Statement of Financial Accounting Standards (SFAS)
No. 115, "Accounting for Certain Investments in Debt and Equity Securities."

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. Property and equipment is depreciated
on a straight-line method over their estimated useful lives ranging from 3 to 7
years. 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.

PATENTS
The costs of patents are being amortized on a straight-line method over a period
of five years.

PRODUCT WARRANTY
The Company records estimated warranty costs on the accrual basis of accounting.
These reserves are based on applying historical returns and cost experience to
the current level of product shipments.

<PAGE>   16




REVENUE RECOGNITION
Revenue from product sales is recognized at the time of shipment. Revenue for
license and royalty fees is recognized when earned.

RESEARCH AND DEVELOPMENT COSTS
Research and development costs are charged to operations in the year incurred.

INCOME TAXES
The Company follows the provisions of SFAS No. 109, "Accounting for Income
Taxes" (SFAS 109). Under SFAS 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.

RECLASSIFICATIONS
Certain reclassifications have been made to the Company's 1997 financial
statements to agree with current year classifications.

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. The statement 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:

4.  SHAREHOLDERS' EQUITY

COMMON STOCK
The Company has 25,000,000 authorized shares which have a par value of $.20 per
share. As of December 31, 1997 and 1998, there are 5,727,350 and 5,920,464
issued shares, respectively.

STOCK REPURCHASE PROGRAM
On April 22, 1997, the Company's Board of Directors authorized a program to
repurchase up to 200,000 shares of its common stock over the next two years. The
shares will be utilized to provide stock under certain employee benefit
programs. The number of shares that the Company intends to purchase and the time
of such purchases will be determined by the Company, at its discretion. The
Company plans to use existing cash and short-term investments to finance the
purchases. As of December 31, 1998, the Company had purchased 106,900 shares of
the Company's common stock under this program.

RESTRICTED STOCK
In May 1989, the Company adopted the Tollgrade Communications, Inc., Restricted
Stock Employee Incentive Plan (the Plan), which provides for the granting of
restricted common stock to key employees. A maximum of 140,000 shares were
issuable under the Plan. During 1995, 18,960 shares of restricted stock under
the Plan were issued. Effective upon approval by the Company's Board of
Directors of the 1995 Long-Term Incentive Compensation Plan, the Plan was
terminated. No shares of restricted stock were granted under the 1995 Long-Term
Incentive Compensation Plan in 1997 and 1998.

     All shares of restricted stock were issued at no cost. Generally, the
recipients of the restricted stock are required to continue in the employment of
the Company for three to five years after the date of issuance for ownership to
vest. The unearned compensation related to the restricted stock is being charged
to expense over the vesting period, using the market value at the issuance date
of $10.00, as determined by the Board of Directors.

     Compensation expense was $52,356, $52,344 and $28,934 in 1996, 1997 and
1998, respectively. In 1996, 1997 and 1998, 2,440, 350 and 700 shares of
restricted stock, respectively, were forfeited due to the termination of certain
employees. Accordingly, the compensation expense recorded for these shares in
prior periods amounting to $9,487, $18,408 and $7,000 was reversed in 1996, 1997
and 1998, respectively. At December 31, 1998, all shares of restricted common
stock granted had vested.

STOCK COMPENSATION PLANS
Under the Company's stock compensation plans, officers and other employees may
be granted options to purchase shares of the Company's common stock. The option
price on all outstanding options is equal to the fair market value of the stock
at the date of the grant, as defined. The options generally vest ratably over a
two-year period, with one-third vested upon grant. The Company's option programs
cover all employees and are used to attract and retain qualified personnel in
all positions.

     On April 22, 1997, the shareholders of the Company approved an amendment of
the 1995 Long-Term Incentive Compensation Plan to increase the number of shares
authorized for issuance under the plan by 375,000 and to allow for inclusion of
non-employee directors under the plan.

     The Company's Board of Directors adopted the 1998 Employee Incentive
Compensation Plan on January 29, 1998 and further amended such plan on April 10,
1998. All full-time active employees of the Company, excluding officers and
directors, are eligible to participate in the plan. The aggregate number of
shares of the Company's common stock which may be issued under the plan is
600,000 shares, subject to proportionate adjustment in the event of stock splits
and similar events. The shares authorized but not granted under these plans at
December 31, 1997 and 1998 were as follows:

     Certain employees and directors of the Company were granted stock options
under the 1995 Long-Term Incentive Compensation Plan and the 1998 Employee
Incentive Compensation Plan and various other agreements. The Company has
adopted the disclosure-only provisions of SFAS No. 123 "Accounting for
Stock-Based Compensation," but applies Accounting Principles Board Opinion No.
25 and related interpretations in accounting for its plans. If the Company had
elected to recognize compensation cost for these stock options based on the fair
value at the grant dates for awards granted under those plans in 1996, 1997 and
1998 consistent with the method prescribed by SFAS No. 123, net income and
earnings per share would have been changed to the pro forma amounts indicated

     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 1996, 1997 and 1998: expected volatility of 46.5% in 1996, 40.4%
in 1997 and 50.8% in 1998; a risk-free interest rate of 5.64% in 1996, 6.10% in
1997 and 4.82% in 1998; and an expected holding period of 4 years. The weighted
average fair value of stock options, calculated using the Black-Scholes
option-pricing model, granted during the year ended 1996, 1997 and 1998, is
$10.71, $8.54 and $7.68, respectively.

     Subsequent to December 31, 1998, the Board of Directors granted an
additional 157,000 options to employees of the Company pursuant to the 1998
Employee Incentive Compensation Plan.

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%.

5.  LICENSE AND ROYALTY FEES
The Company has entered into several technology license agreements with certain
major Digital Loop Carrier (DLC) vendors 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. Royalty fees of $1,893,000, $2,014,000 and $1,903,701 were incurred
in 1996, 1997 and 1998, respectively, and are included in cost of product sales
in the accompanying consolidated statements of operations.

7.  LEASE COMMITMENTS
The Company leases office space and equipment under agreements which are
accounted for as operating leases. The office lease expires December 31, 2001
and may be extended up to an additional 3 years. The equipment lease expires in
September 2003. The Company is also involved in various month-to-month leases
for research and development equipment. In addition, the office lease includes
provisions for possible adjustments in annual future rental commitments relating
to excess taxes and excess maintenance costs that may occur. The Company made
additional rental payments of $4,827, $4,727 and $1,619 in 1998, 1997 and 1996,
respectively.

<TABLE>
<S>                                                                       <C>       
     Minimum annual future rental commitments under noncancelable leases
     as of December 31 are:
     1999................................................................ $  579,917
     2000................................................................    595,577
     2001................................................................    616,457
     2002................................................................     31,817
     2003................................................................     23,863
</TABLE>

     The rent expense for all lease commitments was approximately $335,000,
$354,000 and $425,714 in 1996, 1997 and 1998, respectively.

8.  MAJOR CUSTOMERS, REVENUE CONCENTRATION AND DEPENDENCE ON CERTAIN SUPPLIERS
The Company sells primarily precision electronic equipment to companies in the
telecommunications industry primarily in the United States. Sales are
concentrated primarily with the five Regional Bell Operating Companies (RBOCs)
as well as major independent telephone companies such as Sprint. Sales are
primarily from the Company's metallic channel unit (MCU) product line. The MCU
product line accounted for more than 90% of the Company's net product sales for
1998. The Company expects that revenues from MCU products will continue to
account for a majority of the Company's revenues for the foreseeable future.
Sales to the RBOCs accounted for approximately 86%, 86% and 79% of the Company's
net product sales for fiscal years 1996, 1997 and 1998, respectively. During
fiscal years 1996, 1997 and 1998, sales to two RBOCs individually exceeded 10%
of consolidated revenues and, on a combined basis, comprised 60%, 54% and 54%,
respectively, of the Company's net product sales. At December 31, 1997 and 1998,
accounts receivable-trade included in the consolidated balance sheets related to
these two RBOCs was approximately $3,819,000 and $3,639,000, respectively. Due
to the Company's present dependency on the RBOCs, 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 two 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 material adverse
effect on the Company's results of operations. In addition, shortages of raw
material to, 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.

9.  EMPLOYEE BENEFIT PLANS
The Company adopted a 401(k) benefit plan effective March 1, 1996. Eligible
employees, as defined in the plan, may contribute up to 20% of eligible
compensation or not to exceed the regulatory imposed limit, as defined. The
Company does not make any matching contributions to the plan.
