                              EMPLOYMENT AGREEMENT

        This EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of this
21/st/ day of April 2003 by and between James E. Cashman III (the "Employee")
and ANSYS INC., a Delaware corporation (the "Company").

                              W I T N E S S E T H:

        WHEREAS, Employee has been an officer and a key employee of the Company
and the parties desire to ensure that Employee's expertise, knowledge and
experience will continue to be available to the Company in connection with the
business carried on by the Company currently or in the future.

        NOW, THEREFORE, in consideration of the mutual promises and covenants
herein contained, the parties hereto agree as follows:

Employment.   Subject to the provisions of Section 6, the Company hereby employs
Employee and Employee accepts such employment upon the terms and conditions
hereinafter set forth.

Term of Employment.   Subject to the provisions of Section 6, the term of
Employee's employment pursuant to this Agreement shall commence on and as of the
date hereof (the "Effective Date") and shall remain in effect indefinitely
unless terminated pursuant to Section 6.

Duties; Extent of Service. During Employee's employment under this Agreement,
Employee (i) shall serve as an employee of the Company with the title and
position of President and Chief Executive Officer, reporting to the Board of
Directors of the Company, (ii) shall have such executive responsibilities as the
Board of Directors of the Company shall from time to time designate, (iii) upon
the request of the Board of Directors of the Company, shall serve as an officer
and/or director of any of the Company's subsidiaries, and (iv) shall render all
services reasonably incident to the foregoing. Employee shall not be assigned
any duty which is inconsistent with his position as President and Chief
Executive Officer of the Company. Employee hereby accepts such employment,
agrees to serve the Company in the capacities indicated, and agrees to use
Employee's best efforts in, and shall devote Employee's full working time,
attention, skill and energies to, the advancement of the interests of the
Company and its subsidiaries and the performance of Employee's duties and
responsibilities hereunder (excluding reasonable and appropriate charitable
activities).

Salary, Bonus and Other Compensation.

During Employee's employment under this Agreement, the Company shall pay
Employee a salary at the annualized rate of at least $300,000 per annum (the
"Base Salary"). Such Base Salary shall be subject to withholding under
applicable law, shall be pro rated for partial years and shall be payable in
periodic installments not less frequently than biweekly in accordance with the
Company's usual practice for executive officers of the Company as in effect from
time to time. The Board of Directors

<PAGE>

of the Company will review Employee's Base Salary amount at least annually (and
not later than the anniversary date of this Agreement) and may in its sole
discretion increase the same for the ensuing year.

For each semi-annual period or portion thereof during Employee's employment
under this Agreement (on a calendar year basis), Employee shall be eligible to
participate in any bonus or other performance plan established by the Board of
Directors from time to time for executive officers of the Company (the
"Incentive Bonus"). Employee's Incentive Bonus target shall be $200,000 per
annum (on a calendar year basis), or such higher amount as the Compensation
Committee of Board of Directors may determine from time to time. The actual
amount of the Incentive Bonus shall be based upon Employee's performance
relative to jointly developed, specific corporate and individual objectives (the
"Objectives"). In the event that Employee exceeds the Objectives, the Incentive
Bonus will be increased as set forth in the Objectives.

The Compensation Committee of the Board of Directors or the Chairman of the
Board of Directors shall meet with Employee on or prior to each anniversary of
this Agreement to discuss the Employee's Base Salary and Incentive Bonus for the
following year.

Benefits.

During Employee's employment under this Agreement, Employee shall be entitled to
participate in any and all medical, pension, profit sharing, dental and life
insurance plans and disability income plans, stock option plans, retirement
arrangements and other employment benefits as in effect from time to time for
executive officers of the Company generally ("Benefit Plans"). Such
participation shall be subject to (i) the terms of the applicable plan documents
(including, as applicable, provisions granting discretion to the Board of
Directors of the Company or any administrative or other committee provided for
therein or contemplated thereby) and (ii) generally applicable policies of the
Company.

During Employee's employment under this Agreement, Employee shall receive paid
vacation annually in accordance with the Company's practices for executive
officers, as in effect from time to time, but in any event not less than four
(4) weeks per calendar year. Unused vacation time in any calendar year, not to
exceed eight (8) weeks on an aggregate and cumulative basis, may accumulate for
later use, subject to the establishment of arrangements mutually satisfactory to
Employee and the Board of Directors of the Company with respect to the
management and supervision of the business affairs of the Company during his
absence. Upon termination of Employee's employment with the Company, Employee
shall receive Base Salary in respect of each week of accrued but unused vacation
time, not to exceed eight (8) weeks, in addition to any of the other payments
that may otherwise be due to Employee under the provisions of this Agreement
following such termination.

The Company shall promptly reimburse Employee for all reasonable business
expenses incurred by Employee during Employee's employment hereunder in
accordance with the Company's practices

<PAGE>

for senior executive officers of the Company, as in effect from time to time.

During Employee's employment under this Agreement, the Company shall provide
Employee with a car allowance of $600 per month and shall reimburse Employee for
all gas, oil, maintenance and insurance for Employee's automobile.

The Company will purchase on behalf of Employee a term life insurance policy
providing a death benefit of $2,000,000 in the event of Employee's death and
naming such person or persons as Employee may designate as loss payee or payees
and maintain such policy in effect during the term of Employee's employment
under this Agreement. The obligation to purchase and the maintenance of such
life insurance policy, however, shall be contingent upon Employee's satisfactory
completion of all requirements in connection therewith including, without
limitation, a physical examination.

Compliance with the provisions of this Section 5 shall in no way create or be
deemed to create any obligation, express or implied, on the part of the Company
or any of its affiliates with respect to the continuation of any particular
benefit or other plan or arrangement maintained by them or their subsidiaries as
of or prior to the date hereof or the creation and maintenance of any particular
benefit or other plan or arrangement at any time after the date hereof, except
as contemplated by Section 5(b), 5(c), 5(d) and 5(e).

Termination and Termination Benefits. Notwithstanding the provisions of Section
2, Employee's employment under this Agreement shall terminate under the
following circumstances set forth in this Section 6. It is expressly agreed and
understood that if this Agreement is terminated as provided in this Section 6,
it shall not impair or otherwise affect Employee's Continuing Obligations (as

written notice to the Board of Directors at least sixty (60) days prior to such
termination. For purposes of this Agreement, "Good Reason" shall mean any

remedied within thirty (30) days after delivery to Company by the Employee of
written notice thereof.

Certain Termination Benefits. Unless otherwise specifically provided in this
Agreement or otherwise required by law, all compensation and benefits payable to
Employee under this Agreement shall terminate on the date of termination of
Employee's employment under this Agreement. Notwithstanding the foregoing, in
the event of termination of Employee's employment with the Company pursuant to
Section 6(d) or 6(e) above, subject to the signing by Employee, and the
effectiveness of, a general release in form and substance reasonably
satisfactory to Employee and the Company, the Company shall provide to Employee
the following termination benefits ("Termination Benefits"):

any earned but unpaid Base Salary;

continuation of Employee's Base Salary at the rate then in effect pursuant to
Section 4(a) plus an amount equal to Employee's target bonus amount ($200,000)
or such higher bonus amount as may be the Employee's target bonus for the
current fiscal year under Section 4(b) (with the bonus amount payable on a
monthly, prorated basis);

continuation of Employee's then-existing benefits as provided in Sections 5(a)
(other than his participation in plans in which Employee may not participate as
a matter of law following the termination of his employment) and 5(e);

continuation of group health plan benefits to the extent authorized by and
consistent with 29 U.S.C. Section 1161 et seq. (commonly known as "COBRA"), at
Employee's own cost; and

<PAGE>

outplacement services as selected by the Employee in an amount not to exceed in
the aggregate twelve percent (12%) of the Employee's Base Salary at the rate
then in effect.

The Termination Benefits set forth in clauses (ii), (iii) and (v) above shall
continue, so long as Employee is in compliance with Employee's Continuing
Obligations under this Agreement, until the second anniversary of the date of
termination and shall be subject to any applicable withholding; provided,
however, that in the event that the Employee commences any employment or
self-employment (which shall be deemed to include (A) any activity for which
Employee shall receive or be entitled to receive remuneration based upon the
Employee's work efforts or (B) any other business activity from which Employee
derives income) during the period during which the Employee is entitled to
receive Termination Benefits (the "Termination Benefits Period"), the
Termination Benefits set forth in clauses (iii) and (v) above shall cease to be
effective as of the date of commencement of such employment or self-employment.
The Company's liability for Base Salary and bonus continuation pursuant to
Section 6(f)(ii) shall be reduced by the amount of any severance pay due or
otherwise paid to Employee pursuant to any severance pay plan or stay bonus plan
of the Company. Notwithstanding the foregoing, nothing in this Section 6(f)
shall be construed to affect Employee's right to receive COBRA continuation
entirely at Employee's own cost to the extent that Employee may continue to be
entitled to COBRA continuation. Employee shall be obligated to give prompt
notice of the date of commencement of any employment or self-employment during
the period during which the Employee is entitled to receive Termination Benefits
and shall respond promptly to any reasonable inquiries concerning any employment
or self-employment in which Employee engages during such period. The Company and
Employee agree that the Termination Benefits paid by the Company to Employee
under this Section 6(f) shall be in full satisfaction, compromise and release of
any claims arising out of any termination of Employee's employment pursuant to
Section 6(d) or 6(e).

Disability. If Employee shall be disabled so as to be unable to perform, with or
without reasonable accommodation, the essential functions of Employee's then
existing position or positions under this Agreement for at least 180 consecutive
days, the Board of Directors may remove Employee from any responsibilities
and/or reassign Employee to another position with the Company during the period
of such disability and/or terminate Employee's employment hereunder following
the end of such 180-day period. Notwithstanding any such removal, reassignment
or termination, Employee shall continue to receive Employee's full Base Salary
and benefits under Section 5 of this Agreement (except to the extent that
Employee may be ineligible for one or more such benefits under applicable plan
terms) for not less than twelve (12) months following the date of such
disability and shall receive an additional amount during such period equal to
the Target Bonus ($200,000) or such higher bonus amount as may be the Employee's
target bonus for the current fiscal year under Section 4(b) pro rated for the
portion of the year in which Employee serves as a full time employee, with all
such payments subject to applicable withholding (less any disability pay or sick
pay benefits to which Employee may be entitled under the Company's

<PAGE>

policies). If any question shall arise as to whether during any period Employee
is disabled so as to be unable to perform the essential functions of Employee's
then existing position or positions with or without reasonable accommodation,
Employee may, and at the request of the Company shall, submit to the Company a
certification in reasonable detail by a physician selected by the Company to
whom Employee or Employee's guardian has no reasonable objection as to whether
Employee is so disabled or how long such disability is expected to continue, and
such certification shall for the purposes of this Agreement be conclusive of the
issue. Employee shall cooperate with any reasonable request of the physician in
connection with such certification. If such question shall arise and Employee
shall fail to submit such certification, the Company's determination of such
issue shall be binding on Employee. Nothing in this Section 6(f) shall be
construed to waive Employee's rights, if any, under existing law including,
without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. Section
2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. Section 12101 et
seq.

Death. Employee's employment and all obligations of the Company hereunder shall
terminate in the event of the death of Employee other than any obligation to pay
earned but unpaid Base Salary and an amount equal to Employee's target bonus
($200,000) or such higher bonus amount as may be the Employee's target bonus for
the current fiscal year under Section 4(b), prorated for the number of full
months Employee is employed during the relevant calendar year. Such amounts,
shall be paid reasonably promptly following the date of death, subject to
applicable withholding.

Continuing Obligations. Notwithstanding termination of this Agreement as
provided in this Section 6 or any other termination of Employee's employment
with the Company, it is expressly agreed and understood that Employee's
obligations under (i) Section 8 hereof and (ii) the ANSYS INC. Employee
Agreement Regarding Inventions, Confidentiality and Competitive Activities
signed by Employee on September 9, 1997 (the "Confidentiality Agreement" and
collectively with Section 8 hereof, the "Continuing Obligations") shall survive
any termination of Employee's employment with the Company at any time and for
any reason.

Accrued Benefits. Regardless of the reason for termination of Employee's
employment with the Company, and subject to the terms and provisions of the
applicable plan and/or award documents, Employee (or beneficiary in the event of
death) shall be entitled to all benefits earned and accrued by Employee under
the Company's Benefit Plans.

Termination Pursuant to a Change of Control. If there is a Change of Control (as
defined below in this Section 6(k)) during the term of this Agreement, the
provisions of this Section 6(k) shall apply and shall continue to apply
throughout the remainder of the term of this Agreement. If, within one hundred
and eighty (180) days following a Change of Control, (i) the Employee is removed
from his position as President and Chief Executive Officer of the Company (or is
otherwise subject to any reduction in salary or other forms of cash compensation
or to any material reduction in other benefits) without his consent, (ii) the
surviving entity in such Change of Control (if other than the Company) fails to
assume this Agreement and agree to be bound by

<PAGE>

all of the provisions hereof (including, without limitation, this Section 6) or
(iii) the Employee's employment is terminated by the Company with or without
Cause for any reason other than death or disability, the Company shall provide
to Employee all of the payments and benefits that would be provided to Employee
under Section 6(f) above upon a termination of his employment by the Company
without Cause. "Change of Control" shall mean the occurrence of one or more of
the following events: (A) the dissolution or liquidation of the Company, (B) the
sale of all or substantially all of the assets of the Company on a consolidated
basis to an another person or entity, (C) a merger, reorganization or
consolidation in which the holders of the then outstanding voting securities of
the Company prior to such transaction do not own a majority of the outstanding
voting securities of the surviving or resulting entity immediately upon
completion of such transaction, (D) the sale of all of the outstanding stock of
the Company to an unrelated person or entity, (E) any other transaction where
the holders of the then outstanding voting securities of the Company prior to
such transaction do not own at least a majority of the outstanding voting
securities of the relevant entity after the transaction, or (F) the individuals
who constitute the Company's Board of Directors as of the date of this Agreement
(the "Incumbent Directors") cease for any reason to constitute at least a
majority of the members of such Board (provided, however, that any individual
becoming a director subsequent to the date of this Agreement whose election or
nomination for election was approved by a vote of at least a majority of the
Incumbent Directors (unless the nomination or election (x) was at the request of
an unrelated third-party who has taken steps reasonably calculated to effect a
Change of Control or (y) otherwise arose in connection with or anticipation of
the Change of Control) shall also be deemed to be an "Incumbent Director" for
purposes hereof).

Stock Options.

In the case of a Change of Control, all stock options to purchase stock of the
Company held by Employee shall become fully vested upon the effective date of
and immediately prior to the consummation of the Change of Control. Such stock
options shall terminate on the effective date of the Change of Control, unless
provision is made in the Change of Control in the sole discretion of the parties
thereto for the assumption of such stock options or the substitution for such
stock options of a new stock option of the successor person or entity or a
parent or subsidiary thereof, with appropriate adjustment as to the number and
kind of shares and the per share exercise price. In the event of such
termination, the Company shall give to Employee written notice thereof at least
fifteen (15) days prior to the effective date of the Change of Control. During
such fifteen-day period, Employee may deliver to the Company a notice of
exercise with respect to all or any portion of such stock options, including any
portion that will become fully vested upon the effective day of the Change of
Control; provided, however, that (i) such exercise shall be subject to the
consummation of the Change of Control and (ii) Employee shall not be required to
deliver to the Company the exercise price for such exercised stock option until
the effective date of such Change of Control. After such effective

<PAGE>

date and the termination of such stock options as set forth above, Employee may
not exercise any such stock options.

The provisions of this Section 7 shall be deemed to modify and control any
applicable option agreement to which Employee is a party. Upon termination of
Employee's employment with the Company for any reason, the treatment of
Employee's options shall be as set forth in such agreements.

Non-Competition; Non-Solicitation; Confidentiality; Proprietary Rights.

Employee hereby agrees that during the period commencing on the date hereof and
ending on the Non-Competition Covenant Termination Date (as defined below) (the
"Non-Competition Period"), Employee will not, without the express written
consent of the Company, directly or indirectly, anywhere in the world, engage in
any activity which is, or participate or invest in, or provide or facilitate the
provision of financing to, or assist (whether as owner, part-owner, shareholder,
member, partner, director, officer, trustee, employee, agent or consultant, or
in any other capacity), any company, business, organization, division, business
unit or person other than the Company (or any subsidiary or affiliate of the
Company) that designs, manufactures or sells software supporting
computer-assisted design and/or engineering (each such business, organization,
division, business unit or person, a "Competitor"). Without implied limitation,
the foregoing covenant shall be deemed to prohibit (i) hiring or engaging or
attempting to hire or engage for or on behalf of Employee or any Competitor any
officer or employee of the Company or any of its direct and/or indirect
subsidiaries or affiliates, or any former employee of the Company or any of its
direct and/or indirect subsidiaries or affiliates who was employed during the
six (6) month period immediately preceding the date of such attempt to hire or
engage, (ii) encouraging for or on behalf of Employee or any Competitor any such
officer or employee to terminate his or her relationship or employment with the
Company or any of its direct or indirect subsidiaries or affiliates, (iii)
soliciting for or on behalf of Employee or any Competitor any client of the
Company or any of its direct or indirect subsidiaries or affiliates, or any
former client of the Company or any of its direct or indirect subsidiaries or
affiliates who was a client during the six (6) month period immediately
preceding the date of such solicitation and (iv) diverting to any Competitor any
client or business opportunity of the Company or any of its direct or indirect
subsidiaries or affiliates.

Notwithstanding anything herein to the contrary, Employee may make passive
investments in any enterprise the shares of which are publicly traded if such
investment constitutes less than two percent (2%) of the equity of such
enterprise.

Neither Employee nor any business entity controlled by Employee is a party to
any contract, commitment, arrangement or agreement which could, following the
date hereof, restrain or restrict the Company or any subsidiary or affiliate of
the Company from carrying on its business or restrain or restrict Employee from
performing his employment obligations, and as of the date of this

<PAGE>

Agreement Employee has no business interests whatsoever in or relating to the
industries in which the Company or its subsidiaries or affiliates currently
engage, other than passive investments in the shares of public companies of less
than two percent (2%).

In the course of performing services hereunder, on behalf of the Company (for
purposes of this Section 8 including all predecessors of the Company) and its
affiliates, Employee has had and from time to time will have access to
Confidential Information (as defined below). Employee agrees (i) to hold the
Confidential Information in strict confidence, (ii) not to disclose the
Confidential Information to any person (other than in the regular business of
the Company or its affiliates), and (iii) not to use, directly or indirectly,
any of the Confidential Information for any purpose other than on behalf of the
Company and its affiliates. All documents, records, data, apparatus, equipment
and other physical property, whether or not pertaining to Confidential
Information, that are furnished to Employee by the Company or are produced by
Employee in connection with Employee's employment will be and remain the sole
property of the Company. Upon the termination of Employee's employment with the
Company for any reason and as and when otherwise requested by the Company, all
Confidential Information (including, without limitation, all data, memoranda,
customer lists, notes, programs and other papers and items, and reproductions
thereof relating to the foregoing matters) in Employee's possession or control,
shall be immediately returned to the Company.

Employee hereby confirms that Employee is not bound by the terms of any
agreement with any previous employer or other party that restricts in any way
Employee's use or disclosure of information or Employee's engagement in any
business. Employee represents to the Company that Employee's execution of this
Agreement, Employee's employment with the Company and the performance of
Employee's proposed duties for the Company will not violate any obligations
Employee may have to any such previous employer or other party. In Employee's
work for the Company, Employee will not disclose or make use of any information
in violation of any agreements with or rights of any such previous employer or
other party, and Employee will not bring to the premises of the Company any
copies or other tangible embodiments of non-public information belonging to or
obtained from any such previous employment or other party.

During and after Employee's employment, Employee shall cooperate fully with the
Company in the defense or prosecution of any claims or actions now in existence
or which may be brought in the future against or on behalf of the Company that
relate to events or occurrences that transpired while Employee was employed by
the Company. Employee's full cooperation in connection with such claims or
actions shall include, but not be limited to, being available to meet with
counsel to prepare for discovery or trial and to act as a witness on behalf of
the Company at mutually convenient times. During and after Employee's
employment, Employee also shall cooperate fully with the Company in connection
with any investigation or review of any federal, state or local regulatory
authority as any such investigation or review relates to events or occurrences
that transpired while Employee was employed by the Company. The Company shall
reimburse

<PAGE>

Employee for any reasonable out-of-pocket expenses incurred in connection with
Employee's performance of obligations pursuant to this Section 8(d).

Employee recognizes that the Company and its affiliates possess a proprietary
interest in all of the information described in Section 8(b) and have the
exclusive right and privilege to use, protect by copyright, patent or trademark,
or otherwise exploit the processes, ideas and concepts described therein to the
exclusion of Employee, except as otherwise agreed between the Company and
Employee in writing. Employee expressly agrees that any products, inventions,
discoveries or improvements made by Employee or Employee's agents or affiliates
in the course of Employee's employment, including any of the foregoing which is
based on or arises out of the information described in Section 8(b), shall be
the property of and inure to the exclusive benefit of the Company. Employee
further agrees that any and all products, inventions, discoveries or
improvements developed by Employee (whether or not able to be protected by
copyright, patent or trademark) during the course of his employment, or
involving the use of the time, materials or other resources of the Company or
any of its affiliates, shall be promptly disclosed to the Company and shall
become the exclusive property of the Company, and Employee shall execute and
deliver any and all documents necessary or appropriate to implement the
foregoing.

Employee agrees, while he is employed by the Company, to offer or otherwise make
known or available to it, as directed by the Board of Directors of the Company
and without additional compensation or consideration, any business prospects,
contracts or other business opportunities that Employee may discover, find,
develop or otherwise have available to Employee and further agrees that any such
prospects, contacts or other business opportunities shall be the property of the
Company.

Employee acknowledges that the provisions of this Section 8 are an integral part
of Employee's employment arrangements with the Company.

For purposes of this Agreement:

the term "Confidential Information" shall mean information belonging to the
Company which is of value to the Company or with respect to which the Company
has right in the course of conducting its business and the disclosure of which
could result in a competitive or other disadvantage to the Company. Confidential
Information includes information, whether or not patentable or copyrightable, in
written, oral, electronic or other tangible or intangible forms, stored in any
medium, including, by way of example and without limitation, trade secrets,
ideas, concepts, designs, configurations, specifications, drawings, blueprints,
diagrams, models, prototypes, samples, flow charts processes, techniques,
formulas, software, improvements, inventions, data, know-how, discoveries,
copyrightable materials, marketing plans and strategies, sales and financial
reports and forecasts, customer lists, studies, reports, records, books,
contracts, instruments, surveys, computer disks, diskettes, tapes, computer
programs and business plans, prospects and opportunities (such as possible
acquisitions or dispositions of businesses or facilities) which have been
discussed or considered by the management of the Company. Confidential
Information includes

<PAGE>

information developed by Employee in the course of Employee's employment by the
Company, as well as other information to which Employee may have access in
connection with Employee's employment. Confidential Information also includes
the confidential information of others with which the Company has a business
relationship. Notwithstanding the foregoing, Confidential Information does not
include information in the public domain or reasonably expected to be in the
public domain, unless due to breach of Employee's duties under Section 8(b).

The term "Non-Competition Covenant Termination Date" shall mean the date that is
two (2) years following the date of termination of Employee's employment with
the Company for any reason.

Parties in Interest; Certain Remedies. It is specifically understood and agreed
that this Agreement is intended to confer a benefit, directly or indirectly, on
the Company and its direct and indirect subsidiaries and affiliates, and that
any breach of the provisions of this Agreement by Employee will result in
irreparable injury to the Company and its subsidiaries and affiliates, that the
remedy at law alone will be an inadequate remedy for such breach and that, in
addition to any other remedy it may have, the Company or its subsidiaries and
affiliates shall be entitled to seek to enforce the specific performance of this
Agreement by Employee through both temporary and permanent injunctive relief
without the necessity of posting a bond, but without limitation of their right
to damages and any and all other remedies available to them, it being understood
that injunctive relief is in addition to, and not in lieu of, such other
remedies (and shall be in addition to and not in lieu of the provision of
Section 11).

Dispute Resolution.

All disputes, claims, or controversies arising out of or relating to this
Agreement or any other agreement executed and delivered pursuant to this
Agreement or the negotiation, validity or performance hereof and thereof or the
transactions contemplated hereby and thereby, or the rights and obligations of
the parties hereunder or thereunder, that are not resolved by mutual agreement
shall be resolved solely and exclusively by binding arbitration to be conducted
before JAMS/Endispute, Inc. or its successor, except contemplated by Section 9
in connection with requests for injunctive relief. The arbitration shall be held
in Pittsburgh, Pennsylvania before a single arbitrator and shall be conducted in
accordance with the rules and regulations promulgated by JAMS/Endispute, Inc.
unless specifically modified herein.

The parties covenant and agree that the arbitration shall commence within one
hundred eighty (180) days of the date on which a written demand for arbitration
is filed by any party hereto. In connection with the arbitration proceeding, the
arbitrator shall have the power to order the production of documents by each
party and any third-party witnesses. In addition, each party may take up to
three depositions as of right, and the arbitrator may in his or her discretion
allow additional depositions upon good cause shown by the moving party. However,
the arbitrator shall not have the power to order the answering of
interrogatories or the response to requests for

<PAGE>

admission. In connection with any arbitration, each party shall provide to the
other, no later than seven (7) business days before the date of the arbitration,
the identity of all persons that may testify at the arbitration and a copy of
all documents that may be introduced at the arbitration or considered or used by
a party's witness or expert. The arbitrator's decision and award shall be made
and delivered within six (6) months of the selection of the arbitrator. The
arbitrator's decision shall set forth a reasoned basis for any award of damages
or finding of liability. The arbitrator shall not have power to award damages in
excess of actual compensatory damages and shall not multiply actual damages or
award punitive damages or any other damages that are specifically excluded under
this Agreement, and each party hereby irrevocably waives any claim to such
damages. Each party shall pay its own fees and other out-of-pocket expenses (and
shall pay one-half of the expenses of the arbitrator) in connection with any
arbitration hereunder or litigation relating to the terms hereof. Any party
unsuccessfully refusing to comply with an order of the arbitrators shall be
liable for costs and expenses, including attorneys' fees, incurred by the other
party in enforcing the award.

In the case of temporary or preliminary injunctive relief, any party may proceed

transactions contemplated hereby and thereby, or the rights and obligations of
the parties hereunder or thereunder, and further consents to the sole and
exclusive jurisdiction of the courts of the Commonwealth of Pennsylvania for the
purposes of enforcing the arbitration provisions of this Section 10. Each party
further irrevocably waives any objection to proceeding before JAMS/Endispute,
Inc. based upon lack of personal jurisdiction or to the laying of venue and
further irrevocably and unconditionally waives and agrees not to make a claim in
any court that arbitration before JAMS/Endispute, Inc. has been brought in an
inconvenient forum. Each of the parties hereto hereby consents to service of
process by registered mail at the address to which notices are to be given. Each
of the parties hereto agrees that its or his submission to jurisdiction and its

Scope of Agreement. The parties acknowledge that the time, scope, geographic
area and other provisions of this Agreement, including Section 8 hereof, have
been specifically negotiated by sophisticated parties and agree that all such
provisions are reasonable under the circumstances of the transactions
contemplated hereby, and are given as an integral and essential part of the
transactions contemplated hereby. Employee has independently consulted with
counsel and has been advised in all respects concerning the reasonableness and
propriety of the covenants contained herein, with specific regard to the
business to be conducted by Company and its subsidiaries and affiliates, and
represents that the Agreement is intended to be, and shall be, fully enforceable
and effective in accordance with its terms. Each party agrees that the
provisions of this agreement and the agreements referred to herein shall be
construed in accordance with their fair meaning and not in favor of nor against
either party by reason of the drafting of such agreements.

Severability. In the event that any covenant contained in this Agreement shall
be determined by any court of competent jurisdiction to be unenforceable by
reason of its extending for too great a period of time or over too great a
geographical area or by reason of its being too extensive in any other respect,
it shall be interpreted to extend only over the maximum period of time for which
it may be enforceable and/or over the maximum geographical area as to which it
may be enforceable and/or to the maximum extent in all other respects as to
which it may be enforceable, all as determined by such court in such action. The
existence of any claim or cause of action which Employee may have against the
Company or any of its subsidiaries or affiliates shall not constitute a defense
or bar to the enforcement of any of the provisions of this Agreement.

Miscellaneous. This Agreement shall be governed by and construed under the laws
of the Commonwealth of Pennsylvania, without consideration of its choice of law
provisions, and shall not be amended, modified or discharged in whole or in part
except by an agreement in writing signed by both of the parties hereto. The
failure of either of the parties to require the performance of a term or
obligation or to exercise any right under this Agreement or the waiver of any
breach hereunder shall not prevent subsequent enforcement of such term or
obligation or exercise of such right or the enforcement at any time of any other
right hereunder or be deemed a waiver of any subsequent breach of the provision
so breached, or of any other breach hereunder. This Agreement shall inure to the
benefit of, and be binding upon and assignable to, successors of the Company by
way of merger, consolidation or sale and may not be assigned by Employee. This

<PAGE>

Agreement supersedes and terminates all prior understandings and agreements
between the parties (or their predecessors) relating to the subject matter
hereof, including without limitation the letter dated on or about February 7,
2002; provided that all option agreements to which Employee is a party and the
Confidentiality Agreement referred to in Section 6(h) shall remain in full force
and effect in accordance with their terms. For purposes of this Agreement, the
term "person" means an individual, corporation, partnership, association, trust
or any unincorporated organization; a "subsidiary" means any corporation more
than 50 percent of whose outstanding voting securities, or any partnership,
joint venture or other entity more than 50 percent of whose total equity
interest, is directly or indirectly owned by such person; and an "affiliate" of
a person shall mean, with respect to a person or entity, any person or entity
which directly or indirectly controls, is controlled by, or is under common
control with such person or entity.

Indemnification. At all times (including after the termination of the Employee's
employment with the Company), the Company agrees to obtain and keep in effect
directors and officers liability insurance that provides coverage to the
Employee no less advantageous to the Employee than the coverage applicable to
any other current or former executive officer or director of the Company. In
addition, the Company shall enter into with Employee the same form of
Indemnification Agreement as it has entered into with its directors.
