                                    AGREEMENT

This Agreement, made as of the _____ day of January, 2002 by and between
TOLLGRADE COMMUNICATIONS, INC., a Pennsylvania corporation (the "Corporation")
and CHARLES L. GEIER, JR. (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

       (b)    willfully 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

                                       44
<PAGE>

       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;

              (iii)  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 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.

                                       45

       "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;

       (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.

                                       46

       "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

                                       47
<PAGE>

              (ii)   an amount in cash as liquidated damages for lost future
                     remuneration 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) or (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

                                  (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
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 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. This Agreement specifically supercedes the agreement
              entered into between the Corporation and the Executive dated as of
              August 5, 1996 with respect to the subject matter hereof, and by
              the execution of this Agreement, the previous agreement is hereby
              terminated and of no further force and effect.

       (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.

                                    AGREEMENT

This Agreement, made as of the _____ day of January, 2002 by and between
TOLLGRADE COMMUNICATIONS, INC., a Pennsylvania corporation (the "Corporation")
and JAMES D. COLEMAN (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

       (b)    willfully 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.

                                       52
<PAGE>

       "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;

              (iv)   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 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

                                       53
<PAGE>

       (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;

       (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.

                                       54
<PAGE>

       "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

                                   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) or (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

                                   (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
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 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. This Agreement specifically supercedes the agreement
              entered into between the Corporation and the Executive dated as of
              August 5, 1996 with respect to the subject matter hereof, and by
              the execution of this Agreement, the previous agreement is hereby
              terminated and of no further force and effect.

       (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.
