                                    AGREEMENT


          This Agreement, made as of the 16th day of July, 1999 by and between
TOLLGRADE COMMUNICATIONS, INC., a Pennsylvania corporation (the "Corporation")
and Donald J. Pavlek, 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, or



<PAGE>   2



          (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 involving any other corporation, other
                     than a merger, consolidation, or reorganization that would
                     result in the voting securities of the Corporation
                     outstanding immediately

<PAGE>   3

                    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-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;

<PAGE>   4


          (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 plans or deprive the Executive of any
               material fringe benefit enjoyed by the Executive immediately
               prior to a Change-in-Control (provided, however, that any act or
               failure to act by the Corporation that is on a plan-wide basis,
               i.e., it similarly affects all employees of the Corporation or
               all employees eligible to participate in any such plan, as the
               case may be, shall not constitute Good Reason for Termination);

          (e)  the failure of the Corporation to obtain the assumption of this
               Agreement by any successor as contemplated in SECTION 10(C)
               hereof;

          (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

          (g)  the Corporation's requiring the Executive to be based anywhere
               other than the Corporation's executive offices at which the
               Executive has his principal office immediately prior to a
               Change-in-Control or executive offices located within 50 miles of
               the location of the Corporation's executive offices immediately
               prior to a Change-in-Control, except for required travel on the
               Corporation's business to an extent substantially consistent with
               the Executive's present business travel obligations.

          "NOTICE OF TERMINATION" shall mean a written statement which sets
          forth the specific reason for termination and, if such is claimed to
          be a Cause for Termination or Good Reason for Termination, in
          reasonable detail the facts and circumstances which indicate that such
          is Cause 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.

          "PERSON" shall have the meaning ascribed to such term in Section
          3(a)(9) of the Securities Exchange Act of 1934, as in effect on the
          date hereof and used in Sections 13(d) and 14(d) thereof, including a
          "group" as defined in Section 13(d) thereof.

          "RETIREMENT" shall mean the termination of the Executive's employment
          after age 65 or in accordance with any mandatory retirement
          arrangement with respect to an earlier age agreed to by the Executive.

          "STOCK APPRECIATION RIGHT" shall mean any stock appreciation rights
          issued pursuant to any stock option plan of the Corporation or any
          future stock appreciation rights plan.

          2. TERMS OF EMPLOYMENT. The Executive acknowledges that this Agreement
does not constitute an employment contract and that the Executive's employment
relationship with the Corporation is at-will and not for any particular period.
Rather, this Agreement is only intended to set forth certain liquidated damages
to be paid in the event of termination of the Executive upon the terms and
conditions specified herein.

          3. TERM OF AGREEMENT. The initial term of this Agreement shall be for
a period of four (4) years. Upon expiration of the initial term, the Company
shall, in its sole discretion, determine whether this Agreement shall be renewed
upon such terms it deems advisable.

          4. PAYMENTS FOLLOWING TERMINATION OF EMPLOYMENT UPON A
CHANGE-IN-CONTROL.

          (a)  If the Executive's employment with the Corporation shall be
               terminated:

               (i)   due to the Executive's death,

               (ii)  by the Executive other than the Executive's having
                     terminated for Good Reason for Termination following a
                     Change-in-Control, or

               (iii) by the Corporation due to Cause for Termination or for
                     Disability or Retirement,

               then the Corporation shall have no obligations to the Executive
               other than to pay the Executive any unpaid portion of base salary
               due until the Date of Termination and any other sums due in
               accordance with the then various policies, practices and benefit
               plans of the Corporation.

          (b)  If the Executive's employment with the Corporation shall have
               terminated during the period commencing six months prior to the
               date of a Change-in-Control and ending on the third anniversary
               of a Change-in-Control other than in the circumstances described
               in subsection (a) above, then the Corporation shall pay on or
               before the fifth day following the Date of Termination (or if the
               Date of Termination preceded the date of the Change-in-Control,
               on or before the fifth day following the date of the
               Change-in-Control), to the Executive the following sums:

               (i)  in cash any unpaid portion of the Executive's full base
                    salary for the period from the last period for which the
                    Executive was paid to the Date of Termination, or the date
                    of the Change-in-Control, as the case may be; and

               (ii) an amount in cash as liquidated damages for lost future
                    renumeration equal to the product obtained by multiplying

                    (A)  the lesser of

                           (1) two, or

                           (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 twelve, or

                           (3) a number equal to the greater of (i) one (1.0)
                               and (ii) thirty six (36) less the number of
                               completed months commencing after the date of the
                               Change-in-Control during which the Executive was
                               employed by the Corporation and did not have Good
                               Reason for Termination times (iii) one-twelfth
                               (1/12)

                               times

                    (B)  the sum of

                         (1) the greater of

                              (i) the Executive's annual base salary for the
                                  year in effect on the Date of Termination
                                  (provided that in the case of Termination for
                                  Good Reason by the Executive the date
                                  immediately preceding the date of the earliest
                                  event which gave rise to the Termination for
                                  Good Reason by the Executive shall be used
                                  instead of the Date of Termination)

                                  or

<PAGE>   7


                              (ii) the Executive's annual base salary for the
                                   year in effect on the date of the
                                   Change-in-Control;

                         plus

                         (2)  the greater of

                              (i) the average annual cash award received by the
                                  Executive as incentive compensation or bonus
                                  for one calendar year immediately preceding
                                  the Date of Termination (provided that in the
                                  case of Termination for Good Reason by the
                                  Executive the date immediately preceding the
                                  date of the event which gave rise to the
                                  Termination for Good Reason by the Executive
                                  shall be used instead of the Date 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 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

          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 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 full
               force and effect. If any provision hereof shall be deemed invalid
               or unenforceable, either in whole or in part, this Agreement
               shall be deemed amended to delete or modify, as necessary, the
               offending provision and to alter the bounds thereof in order to
               render it valid and enforceable.

          (h)  This Agreement may be executed in one or more counterparts, each
               of which shall be deemed to be an original but all of which taken
               together will constitute one and the same instrument.

          (i)  If litigation should be brought to enforce, interpret or
               challenge any provision contained herein, the prevailing party
               shall be entitled to its reasonable attorney's fees and
               disbursements and other costs incurred in such litigation and, if
               a money judgment be rendered in favor of the Executive, to
               interest on any such money judgment obtained calculated at the
               prime rate of interest in effect from time to time at Mellon
               Bank, N.A., from the date that the payment should have been made
               or damages incurred under this Agreement.

          IN WITNESS WHEREOF, this Agreement has been executed on the date first
above written.
