                      CHANGE OF CONTROL/SEVERANCE AGREEMENT

         This CHANGE OF CONTROL/SEVERANCE AGREEMENT, dated as of December 23,
2003 by and between PAREXEL International Corporation (together with all
subsidiaries or affiliates hereinafter referred to as the "Company") and Susan
H. Alexander (the "Executive").

         WHEREAS, the Executive has been hired as a senior executive of the
Company and is expected to make major contributions to the Company;

         WHEREAS, the Company desires continuity of management; and

         WHEREAS, the Executive is willing to render services to the Company
subject to the conditions set forth in this Agreement.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the Company and the Executive agree
as follows:

         1.       TERMINATION WITHOUT CAUSE. In the event the Company terminates
the Executive's employment with the Company without "Cause" (as such term is
defined in Section 4(c) below), the Company shall pay to the Executive, within
ten business days following the date of termination, a lump sum amount (net of
any required withholding) equal to: (i) twelve (12) months of monthly base
salary (at the highest monthly base salary rate in effect for the Executive in
the twelve month period prior to the termination of his employment), plus (ii)
the pro rata share of the target bonus that could have been payable to the
Executive pursuant to the Company's Performance Bonus Plan (assuming continued
employment) during the year in which the termination occurs, based on bonus
arrangements in effect at any time during the twelve month period immediately
prior to the termination of his employment, such pro rata share to be calculated
from the beginning of the fiscal year in which the termination occurs through
the date of termination.

         2.       TERMINATION PRIOR TO A CHANGE OF CONTROL.

         (a)      Notwithstanding the provisions of Section 1 above, if, within
nine months prior to a Change of Control (as such term is defined in Section
4(b) below) and subsequent to the commencement of substantive discussions that
ultimately result in the Change of Control, the Company terminates the
Executive's employment with the Company without Cause, the Company shall:

                  (1)      Pay to the Executive, within ten (10) business days
                           following the Change of Control, a lump sum amount
                           (net of any required withholding) equal to: (i)
                           twelve (12) months of monthly base salary (at the
                           highest monthly base salary rate in effect for the
                           Executive in the twelve month period prior to

<PAGE>

                           the termination of his employment), plus (ii) the
                           target bonus that could have been payable to the
                           Executive (assuming continued employment) during the
                           year in which the Change of Control occurs based on
                           bonus arrangements in effect at any time during the
                           twelve month period immediately prior to the
                           termination of his employment; and

                  (2)      Provide the Executive and his dependents with life,
                           accident, health and dental insurance substantially
                           similar to that which the Executive was receiving
                           immediately prior to the termination of his
                           employment until the earlier of: (i) the date which
                           is twelve (12) months following the Change of
                           Control; or (ii) the date the Executive commences
                           subsequent employment; and

                  (3)      On the Change of Control, cause any unexercisable
                           installments of any stock options of the Company or
                           any subsidiary or affiliate of the Company held by
                           the Executive on the Executive's last date of
                           employment with the Company that have not expired to
                           become exercisable on the Change of Control;
                           provided, however, that: (i) such acceleration of
                           exercisability shall not occur as to any option if
                           the Change of Control does not occur within the
                           period within which the Executive may exercise such
                           option after a termination of employment in
                           accordance with the provisions of the relevant option
                           agreement and option plan; and (ii) any such
                           acceleration of exercisability shall not extend the
                           period after a termination of employment within which
                           any option may be exercised by the Executive in
                           accordance with the provisions of the relevant option
                           agreement and option plan; and

                  (4)      On the Change of Control, cause any unvested portion
                           of any qualified or non-qualified capital
                           accumulation benefits to become immediately vested
                           (subject to applicable law);

provided, however, that any amounts and benefits set forth in this Section 2
shall be reduced by any and all other severance or other amounts or benefits
paid or payable to the Executive as a result of the termination of his or her
employment.

         3.       TERMINATION FOLLOWING A CHANGE OF CONTROL.

         (a)      Notwithstanding the provisions of Section 1 above, if, at any
time during a period commencing with a Change of Control and ending eighteen
months after such Change of Control, the Company terminates the Executive's
employment without Cause or the Executive terminates his employment with the
Company for "Good Reason" (provided, however, that any such termination by the
Executive must occur promptly (and in any event within 90 days) after the
occurrence of the event or events constituting "Good Reason"), the Company
shall:

                  (1)      Pay to the Executive, within ten (10) business days
                           following the Executive's last date of employment, a
                           lump sum amount (net of any required withholding)
                           equal to: (i) twelve (12) months of monthly base
                           salary (at the highest monthly base salary rate in
                           effect for such Executive in the twelve (12) month
                           period prior to the termination of his or her
                           employment), plus (ii) the target bonus that could
                           have been payable to such Executive (assuming
                           continued employment) during the year in which the
                           termination of employment occurs based on bonus
                           arrangements in effect immediately prior to the
                           termination of his or her employment (all payments
                           under Sections 1, 2 and this Section 3(a) being
                           referred to collectively, as the "Severance
                           Payments"); and

                  (2)      Provide the Executive and his or her dependents with
                           life, accident, health and dental insurance
                           substantially similar to that which the Executive was
                           receiving immediately prior to the termination of his
                           or her employment until the earlier of: (i) the date
                           which is twelve (12) months following the termination
                           of the Executive's employment; or (ii) the date the
                           Executive commences subsequent employment; and

                  (3)      Cause any unexercisable installments of any stock
                           options of the Company or any subsidiary or affiliate
                           of the Company held by the Executive on the
                           Executive's last date of employment with the Company
                           that have not expired to become exercisable on such
                           last date of employment; provided, however, that: (i)
                           such acceleration of exercisability shall not occur
                           as to any option if the Change of Control does not
                           occur within the period within which the Executive
                           may exercise such option after a termination of
                           employment in accordance with the provisions of the
                           relevant option agreement and option plan; and (ii)
                           any such acceleration of exercisability shall not
                           extend the period after a termination of employment
                           within which any option may be exercised by the
                           Executive in accordance with the provisions of the
                           relevant option agreement and option plan; and

                  (4)      Cause any unvested portion of any qualified and
                           non-qualified capital accumulation benefits to become
                           immediately vested, subject to applicable law;

provided, however, that any amounts and benefits set forth in this Section 3
shall be reduced by any and all other severance or other amounts or benefits
paid or payable to the Executive as a result of the termination of his or her
employment.

         (b)      For purposes of Section 3 above, "Good Reason" shall mean the
occurrence of one or more of the following events following a Change of Control,
as the case may be: (i) the assignment to the Executive of any duties
inconsistent in any adverse, material respect with his position, authority,
duties or responsibilities immediately prior to the Change of Control or any
other action by the Company which results in a material diminution in such
position, authority,

                                     - 3 -
<PAGE>

duties or responsibilities; (ii) a material reduction in the aggregate of the
Executive's base or incentive compensation or the termination of the Executive's
rights to any employee benefits immediately prior to the Change of Control,
except to the extent any such benefit is replaced with a comparable benefit, or
a reduction in scope or value thereof; or (iii) a relocation of the Executive's
place of business which results in the one-way commuting distance for the
Executive increasing by more than 25 miles from the location thereof immediately
prior to the Change of Control (provided, however, that travel consistent with
past practices for business purposes shall not be considered "commuting" for
purposes of this clause (iii)) or (iv) a failure by the Company to obtain the
agreement referenced in Section 4(f).

         4.       GENERAL.

         (a)      In the event the Executive's employment with the Company is
terminated by the Company for "Cause", or the Executive terminates his
employment with the Company other than during the specific time periods set
forth in Section 3 or for any reason other than Good Reason, the Executive shall
not be entitled to the severance benefits or other considerations described
herein by virtue of this Agreement.

         (b)      For purposes of this Agreement, "Change of Control" shall mean
the closing of: (i) a merger, consolidation, liquidation or reorganization of
the Company into or with another Company or other legal person, after which
merger, consolidation, liquidation or reorganization the capital stock of the
Company outstanding prior to consummation of the transaction is not converted
into or exchanged for or does not represent more than 50% of the aggregate
voting power of the surviving or resulting entity; (ii) the direct or indirect
acquisition by any person (as the term "person" is used in Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1934, as amended) of more than 50% of
the voting capital stock of the Company, in a single or series of related
transactions; or (iii) the sale, exchange, or transfer of all or substantially
all of the Company's assets (other than a sale, exchange or transfer to one or
more entities where the stockholders of the Company immediately before such
sale, exchange or transfer retain, directly or indirectly, at least a majority
of the beneficial interest in the voting stock of the entities to which the
assets were transferred).

         (c)      For purposes of this Agreement, "Cause" shall mean: (i) the
commission by the Executive of a felony, either in connection with the
performance of his obligations to the Company or which adversely affects the
Executive's ability to perform such obligations; (ii) gross negligence, breach
of fiduciary duty or breach of any confidentiality, non-competition or
developments agreement in favor of the Company; or (iii) the commission by the
Executive of an act of fraud or embezzlement or other acts in intentional
disregard of the Company which result in loss, damage or injury to the Company,
whether directly or indirectly.

         (d)      Notwithstanding anything to the contrary in this Agreement, if
any portion of any payments received by the Executive from the Company (whether
payable pursuant to the terms of this Agreement or any other plan, agreement or
arrangement with the Company, its successors or any person whose actions result
in a change of control of the Company) shall be subject to tax imposed by
Section 4999 of the Internal Revenue Code of 1986, as amended or any successor
statutory provision, the Company shall pay to the Executive such additional
amounts as are

                                     - 4 -
<PAGE>

necessary so that, after taking into account any tax imposed by Section 4999 (or
any successor statutory provision), and any federal and state income taxes
payable on any such tax, the Executive is in the same after-tax position that he
or she would have been if such Section 4999 (or any successor statutory
provision) did not apply and no payments were made pursuant to this Section
4(d). The Executive and the Company shall each reasonably cooperate with the
other in connection with any administrative or judicial proceedings concerning
the existence or amount of liability for Excise Tax with respect to the
Payments. All determinations required to be made under this Section 4(d),
including whether a Gross-Up Payment is required and the amount of such Gross-Up
Payment, shall be made by the Company, after consultation with its tax and
accounting advisors.

         (e)      The parties hereto expressly agree that the payments by the
Company to the Executive in accordance with the terms of this Agreement will be
liquidated damages, and that the Executive shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, nor shall any profits, income, earnings or other benefits from any
source whatsoever create any mitigation, offset, reduction or any other
obligation on the part of the Executive.

         (f)      Except as otherwise provided herein, this Agreement shall be
binding upon and inure to the benefit of the Company and any successor (whether
direct or indirect, by purchase, merger, consolidation, reorganization or
otherwise) of the Company; provided, however, that as a condition of closing any
transaction which results in a Change of Control, the Company shall obtain the
written agreement of any successor (whether direct or indirect, by purchase,
merger, consolidation, reorganization or otherwise) of the Company to be bound
by the provisions of this Agreement as if such successor were the Company and
for purposes of this Agreement, any such successor of the Company shall be
deemed to be the "Company" for all purposes.

         (g)      Nothing in this Agreement shall create any obligation on the
part of the Company or any other person to continue the employment of the
Executive. If the Executive elects to receive the severance and benefits set
forth in Sections 1, 2 or 3, the Executive shall not be entitled to any other
salary continuation or severance benefits in the event of his cessation of
employment with the Company.

         (h)      Nothing herein shall affect the Executive's obligations under
any key employee, non-competition, confidentiality, option or similar agreement
between the Company and the Executive currently in effect or which may be
entered into in the future.

         (i)      This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts. This Agreement
constitutes the entire Agreement between the Executive and the Company
concerning the subject matter hereof and supersedes any prior negotiations,
understandings or agreements concerning the subject matter hereof, whether oral
or written, and may be amended or rescinded only upon the written consent of the
Company and the Executive. The invalidity or unenforceability of any provision
of this Agreement shall not affect the other provisions of this Agreement and
this Agreement shall be construed and reformed to the fullest extent possible.
The Executive may not assign any of his rights or obligations under this
Agreement; the rights and obligations of the Company under this

                                     - 5 -
<PAGE>

Agreement shall inure to the benefit of, and shall be binding upon, the
successors and assigns of the Company. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the date first written above.

                                AGREEMENT/WAIVER

         It is hereby agreed by and between __________________ (the "Executive")

         2.       Settlement of Amounts Due the Executive. The Executive agrees
that the amounts set forth above in Section 1, together with any amounts
previously provided to the Executive by the Company, shall be complete and
unconditional payment, settlement, satisfaction and accord with respect to all
obligations and liabilities of the Company and any of its affiliated companies

has had against the Releasees under the Agreement, including, but not limited
to, any federal, state or local law or regulation dealing with either employment
or employment discrimination such as those laws or regulations concerning
discrimination on the basis of age, race, color, religion, creed, sex, sexual-

Releasees from any and all claims as stated above that the Executive could make
on his/her own behalf or on behalf of others, but also those claims which might
be made by any other person or organization on behalf of the Executive, and the
Executive specifically waives any right to become, and promises not to become, a
member of any class in a case in which a claim or claims against the Releasees
are made involving any matters which arise out of, or in connection with, the
Agreement. Nothing in this agreement is to be construed as an admission by the
Releasees of any liability or unlawful conduct whatsoever.

         4.       Waiver of Rights and Claims Under the Age Discrimination and
Employment Act of 1967.

         (a)      The Executive has been informed that since he is 40 years of
age or older, he has or might have specific rights and/or claims under the Age

and/or claims to the extent that such rights and/or claims arose prior to the

         5.       Confidentiality. The Executive agrees he shall not divulge or

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This EXECUTIVE EMPLOYMENT AGREEMENT ("Agreement") is made as of the
23rd day of January 2004 between MOLDFLOW CORPORATION, a Delaware corporation
(the "Company"), and TIMOTHY TRIPLETT ("Executive").

         WHEREAS, the Company and the Executive are parties to a certain
Agreement and Plan of Merger dated as of January 23, 2004, by and among the
Company, MF Merger Sub I, Inc., American MSI Corporation ("AMSI"), Timothy L.
Triplett and Deborah A. Triplett as co-trustees of the Timothy and Deborah
Triplett Family Trust, Deborah A. Triplett and Executive (the "Purchase
Agreement");

         WHEREAS, it is a condition to the Company's and Executive's obligations
under the Purchase Agreement that the Company and Executive enter into this
Agreement; and

         WHEREAS, the Company desires to employ Executive and Executive desires
to be employed by the Company on the terms contained herein.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

         1.       EMPLOYMENT. The term of this Agreement shall extend from the
date hereof (the "Commencement Date") until the first anniversary of the
Commencement Date and shall automatically be extended for one additional year on
each anniversary thereafter unless, not less than 30 days prior to each such
date, either party shall have given notice that it does not wish to extend this
Agreement; provided further, that, following a Change in Control, the term of
this Agreement shall continue in effect for a period of not less than twelve
(12) months beyond the month in which the Change in Control occurred. The term
of this Agreement shall be subject to termination as provided in Paragraph 4 and
may be referred to herein as the "Period of Employment."

         2.       POSITION AND DUTIES. During the Period of Employment,
Executive shall serve as the Executive Vice President, Manufacturing Solutions,
and shall have such duties as may from time to time be prescribed by the Chief
Executive Officer or the Board of Directors of the Company (the "Board").
Executive shall devote his full working time and efforts to the business and
affairs of the Company.

         3.       COMPENSATION AND RELATED MATTERS.

                  (a)      BASE SALARY AND INCENTIVE COMPENSATION. Executive's
         initial annual base salary shall be $200,000. Executive's base salary
         shall be redetermined annually by the Chief Executive Officer, the
         Board or a Committee thereof. The annual base salary in effect at any
         given time is referred to herein as "Base Salary." The Base Salary
         shall be

                                       1
<PAGE>

         payable in a manner consistent with the general payroll policy of the
         Company. In addition to Base Salary, Executive shall be eligible to
         participate in such incentive compensation plans and Employee Benefit
         Plans as the CEO, the Board or a Committee thereof shall determine from
         time to time. As used herein, the term "Employee Benefit Plans"
         includes, without limitation, each pension and retirement plan;
         supplemental pension, retirement and deferred compensation plan;
         savings and profit-sharing plan; stock ownership plan; stock purchase
         plan; stock option plan; life insurance plan; medical insurance plan;
         disability plan; and health and accident plan or arrangement
         established and maintained by the Company.

                  (b)      VACATIONS. Executive shall be entitled to twenty (20)
         paid vacation days in each fiscal year, which shall be accrued ratably
         during the fiscal year, and Executive shall also be entitled to all
         paid holidays given by the Company to its executives.

                  (c)      ADDITIONAL BENEFITS. The Company will reimburse the
         Executive for the cost of a supplemental policy of long-term disability
         insurance for the Executive; provided that such policy can be purchased
         under normal terms and conditions given the age of the Executive.

                  (d)      INDEMNIFICATION AND DIRECTORS' AND OFFICERS'
         INSURANCE. During Executive's employment and for the period of time
         following termination of the Executive for any reason during which time
         Executive could be subject to any claim based on his position in the
         Company, Executive shall receive the maximum indemnification protection
         from the Company as permitted by the Company's by-laws and shall
         receive directors' and officers' insurance coverage equivalent to that
         which is provided to any other director or officer of the Company.

         4.       TERMINATION. Except for termination as specified in
Subparagraph 4(a), any termination of Executive's employment by the Company or
any such termination by Executive shall be communicated by written notice of
termination to the other party hereto (a "Notice of Termination"). Executive's
employment hereunder may be terminated without any breach of this Agreement
under the following circumstances:

                  (a)      DEATH. Executive's employment hereunder shall
         terminate upon his death.

                  (b)      DISABILITY. If, as a result of Executive's incapacity
         due to physical or mental illness, Executive shall have been absent
         from his duties hereunder on a full-time basis for one hundred eighty
         (180) calendar days in the aggregate in any twelve (12) month period,
         the Company may terminate Executive's employment hereunder.

                  (c)      TERMINATION BY COMPANY FOR CAUSE. At any time during
         the Period of Employment, the Company may terminate Executive's
         employment hereunder for Cause if such termination is approved by not
         less than a majority of the Company's Board of Directors. For purposes
         of this Agreement, "Cause" shall mean: (A) conduct by Executive
         constituting a material act of willful misconduct in connection with
         the

                                       2
<PAGE>

         performance of his duties; (B) criminal or civil conviction of
         Executive, a plea of nolo contendere by Executive or conduct by
         Executive that would reasonably be expected to result in material
         injury to the reputation of the Company if he were retained in his
         position with the Company; (C) continued, willful and deliberate
         non-performance by Executive of his duties hereunder (other than by
         reason of Executive's physical or mental illness, incapacity or
         disability) which has continued for more than thirty (30) days
         following written notice of such non-performance from the Board; or (D)
         a breach by Executive of any of the provisions contained in Paragraph 7
         of this Agreement or Paragraph 5.2 of the Purchase Agreement.

                  (d)      TERMINATION WITHOUT CAUSE. At any time during the
         Period of Employment, the Company may terminate Executive's employment
         hereunder without Cause if such termination is approved by a majority
         of the Company's Board of Directors. Any termination by the Company of
         Executive's employment under this Agreement which does not constitute a
         termination for Cause under Subparagraph 4(c) or result from the death
         or disability of the Executive under Subparagraphs 4(a) or (b) shall be
         deemed a termination without Cause. If the Company provides notice to
         Executive under Paragraph 1 that it does not wish to extend the Period
         of Employment, such action shall be deemed a termination without Cause.

                  (e)      TERMINATION BY EXECUTIVE. At any time during the
         Period of Employment, Executive may terminate his employment hereunder
         for any reason.

                  (f)      DATE OF TERMINATION. "Date of Termination" shall
         mean: (A) if Executive's employment is terminated by his death, the
         date of his death; (B) if Executive's employment is terminated under
         Subparagraph 4(b) or under Subparagraph 4(c), the date on which Notice
         of Termination is given; (C) if Executive's employment is terminated by
         the Company under Subparagraph 4(d), thirty (30) days after the date on
         which a Notice of Termination is given; and (D) if Executive's
         employment is terminated by Executive under Subparagraph 4(e), thirty
         (30) days after the date on which a Notice of Termination is given.

         5.       COMPENSATION UPON TERMINATION OR DURING DISABILITY.

                  (a)      If Executive's employment terminates by reason of his
         death, the Company shall, within ninety (90) days of the Date of
         Termination, pay in a lump sum amount to such person as Executive shall
         designate in a notice filed with the Company or, if no such person is
         designated, to Executive's estate, Executive's accrued and unpaid Base
         Salary and accrued vacation to the date of his death, plus his accrued
         and unpaid incentive compensation (including any bonus payment if any,
         under Subparagraph 3(a) that is earned with respect to any financial
         period but which has not yet been authorized for payment by the Board
         of Directors or any committee thereof, which shall be paid if and when
         it is so authorized by the Board of Directors). Upon the Date of
         Termination, all stock options which would otherwise vest over the next
         twelve (12) months shall immediately vest in Executive's estate or
         other legal representatives and become

                                       3
<PAGE>

         exercisable, and Executive's estate or other legal representatives
         shall have twelve (12) months from the Date of Termination or the
         remaining option term, if earlier, to exercise all such stock options
         granted to Executive. All other stock-based grants and awards held by
         Executive shall be canceled upon the death of Executive in accordance
         with their terms. For a period of one (1) year following the Date of
         Termination, the Company shall pay such health and dental insurance
         premiums as may be necessary to allow Executive's spouse and dependents
         to receive health and dental insurance coverage substantially similar
         to coverage they received immediately prior to the Date of Termination.
         In addition to the foregoing, any payments to which Executive's spouse,
         beneficiaries, or estate may be entitled under any Employee Benefit
         Plan shall also be paid in accordance with the terms of such plan. Such
         payments, in the aggregate, shall fully discharge the Company's
         obligations hereunder.

                  (b)      During any period that Executive fails to perform his
         duties hereunder as a result of incapacity due to physical or mental
         illness, Executive shall continue to receive his Base Salary and other
         compensation and benefits provided hereunder. If Executive's employment
         is terminated by the Company pursuant to Paragraph 4(b), then the
         Company shall, through the Date of Termination, pay Executive his
         accrued and unpaid Base Salary plus accrued vacation, at the rate in
         effect at the time Notice of Termination is given, plus accrued and
         unpaid incentive compensation (including any bonus payment if any,
         under Subparagraph 3(a), that is earned with respect to any financial
         period but which has not yet been authorized for payment by the Board
         of Directors or any committee thereof which shall be paid if and when
         it is so authorized by the Board of Directors). Upon the Date of
         Termination, all stock options which would otherwise vest over the next
         twelve (12) months shall immediately vest and become exercisable, and
         Executive shall have twelve (12) months from the Date of Termination or
         the remaining option term, if earlier, to exercise all such stock
         options granted to Executive. All other stock-based grants and awards
         held by Executive shall vest or be canceled upon the Date of
         Termination in accordance with their terms. For a period of one (1)
         year following the Date of Termination, the Company shall pay such
         health and dental insurance premiums as may be necessary to allow
         Executive and Executive's spouse and dependents to receive health and
         dental insurance coverage substantially similar to coverage they
         received prior to the Date of Termination. In addition to the
         foregoing, any payments to which Executive may be entitled under any
         Employee Benefit Plan shall also be paid in accordance with the terms
         of such plan. Such payments, in the aggregate, shall fully discharge
         the Company's obligations hereunder.

                  (c)      If Executive's employment is terminated by Executive
         as provided in Subparagraph 4(e) (including where Executive provides
         notice to the Company under Paragraph 1 that he does not wish to extend
         the Period of Employment), then the Company shall, through the Date of
         Termination, pay Executive his accrued and unpaid Base Salary plus
         accrued vacation, at the rate in effect at the time Notice of
         Termination is given. Thereafter, the Company shall have no further
         obligations to Executive except as otherwise expressly provided under
         this Agreement. In addition, all vested but unexercised stock options
         held by Executive as of the Date of Termination must be

                                       4
<PAGE>

         exercised by Executive within three (3) months following the Date of
         Termination or by the end of the option term, if earlier. All other
         stock-based grants and awards held by Executive shall vest or be
         canceled upon the Date of Termination in accordance with their terms.
         Notwithstanding the foregoing, if the Company determines that the
         Executive is in breach of any of the provisions contained in Paragraph
         7 of this Agreement or any of the provisions contained in Section 5.2
         of the Purchase Agreement during the three (3) month period from the
         Date of Termination, then all stock options held by the Executive shall
         immediately terminate and be of no further force and effect.

                  (d)      If Executive's employment is terminated by the
         Company without Cause as provided in Subparagraph 4(d), then the
         Company shall, through the Date of Termination, pay Executive his
         accrued and unpaid Base Salary plus accrued vacation, at the rate in
         effect at the time Notice of Termination is given, and his accrued and
         unpaid incentive compensation (including any bonus payment if any,
         under Subparagraph 3(a), that is earned with respect to any financial
         period but which has not yet been authorized for payment by the Board
         of Directors or any committee thereof which shall be paid if and when
         it is so authorized by the Board of Directors). In addition, subject to
         signing by Executive of a general release of claims in a form and
         manner satisfactory to the Company, the Company shall provide the
         following benefits to Executive:

                           (i)      The Company shall pay Executive an amount
         equal to one (1) times the sum of (A) the Executive's Base Salary in
         effect on the Date of Termination, and (B) the Executive's average
         annual bonus or other variable cash compensation (including
         commissions) over the five (5) fiscal years immediately prior to the
         year of termination (the "Termination Amount"). Notwithstanding the
         foregoing, in the event that the Executive shall have been employed
         with the Company (not to include the Executive's previous employment
         with AMSI, prior to the date of this Agreement) for less than five (5)
         fiscal years immediately prior to the year of termination, then in such
         case the Termination Amount shall be calculated as the average annual
         bonus or other variable cash compensation (including commissions) over
         the number of full fiscal years that Executive was employed by the
         Company prior to the year of termination. The Termination Amount shall
         be calculated by the Company within ten (10) business days following
         the Date of Termination and communicated to the Executive in writing
         and shall then be paid out in accordance with the Company's standard
         payroll practices, in equal installments over twelve (12) months
         following the Date of Termination. Notwithstanding the foregoing, if
         the Company determines that the Executive is in breach of any of the
         provisions contained in Paragraph 7 of this Agreement or any of the
         provisions contained in Section 5.2 of the Purchase Agreement during
         the period over which the Termination Amount is being paid, then all
         further payments of the Termination Amount shall immediately cease.

                           (ii)     Upon the Date of Termination, all stock
         options which would otherwise vest over the next twelve (12) months
         shall immediately vest and become exercisable, and Executive shall have
         twelve (12) months from the Date of Termination or the remaining option
         term, if earlier, to exercise all such stock options granted to

                                       5
<PAGE>

         Executive. All other stock-based grants and awards held by Executive
         shall be canceled upon the Date of Termination in accordance with their
         terms. Notwithstanding the foregoing, if the Company determines that
         the Executive is in breach of any of the provisions contained in
         Paragraph 7 of this Agreement or any of the provisions contained in
         Section 5.2 of the Purchase Agreement during the twelve (12) month
         period from the Date of Termination, then all stock options held by the
         Executive shall immediately terminate and be of no further force and
         effect.

                           (iii)    The Company shall, for a period of one (1)
         year commencing on the Date of Termination, pay such health and dental
         insurance premiums as may be necessary to allow Executive and
         Executive's spouse and dependents to continue to receive health and
         dental insurance coverage substantially similar to coverage they
         received prior to the Date of Termination. In addition to the
         foregoing, any payments to which Executive may be entitled under any
         Employee Benefit Plan shall also be paid in accordance with the terms
         of such plan. Notwithstanding the foregoing, if the Company determines
         that the Executive is in breach of any of the provisions contained in
         Paragraph 7 of this Agreement or any of the provisions contained in
         Section 5.2 of the Purchase Agreement during the period over which
         payments are being made pursuant to this Subparagraph 5(d)(iii), then
         all further payments under this Subparagraph 5(d)(iii) shall
         immediately cease.

                  (e)      If Executive's employment is terminated by the
         Company for Cause as provided in Subparagraph 4(c), then the Company
         shall, through the Date of Termination, pay Executive his accrued and
         unpaid Base Salary, plus accrued vacation, at the rate in effect at the
         time Notice of Termination is given. Thereafter, the Company shall have
         no further obligations to Executive except as otherwise expressly
         provided under this Agreement. In addition, all stock options held by
         Executive as of the Date of Termination shall cease to vest as of the
         Date of Termination and Executive shall have thirty (30) days from the
         Date of Termination or the remaining option term, if earlier, to
         exercise all such vested stock options. All other stock-based grants
         and awards held by Executive shall be canceled upon the Date of
         Termination in accordance with their terms. Notwithstanding the
         foregoing, if the Company determines that the Executive is in breach of
         any of the provisions contained in Paragraph 7 of this Agreement or any
         of the provisions contained in Section 5.2 of the Purchase Agreement
         during the thirty (30) day period from the Date of Termination, then
         all stock options held by the Executive shall immediately terminate and
         be of no further force and effect.

                  (f)      Nothing contained in the foregoing Subparagraphs 5(a)
         through 5(e) shall be construed so as to affect Executive's rights or
         the Company's obligations relating to agreements or benefits that are
         unrelated to termination of employment.

         6.       CHANGE IN CONTROL BENEFIT. Upon a Change in Control of the
Company, the following provisions shall apply and, in the event of the
termination of Executive's employment without Cause following such Change in
Control, shall apply in lieu of, and expressly supersede, the provisions of
Subparagraph 5(d).

                  (a)      CHANGE IN CONTROL.

                           (i)      In the event that within twelve (12) months
         following a Change in Control, the Executive terminates his employment
         for Good Reason (as defined below) or if the Executive's employment is
         terminated by the Company without Cause, the Company shall pay
         Executive an amount equal to 1.5 times the sum of (A) the Executive's
         Base Salary in effect on the Date of Termination, and (B) the
         Executive's cash bonus or other variable cash compensation (including
         commissions) that would be payable to the Executive during the fiscal
         year in which the Change in Control occurred if the Company and the
         Executive had met all of the targets required for a full payment of
         such cash bonus or other variable cash compensation (collectively, the
         "Severance Amount"). The Severance Amount shall be calculated by the
         Company within ten (10) business days following the Date of Termination
         and communicated to the Executive in writing and shall then be paid out
         in accordance with the Company's standard payroll practices, in equal
         installments over the eighteen (18) months following the Date of
         Termination. Notwithstanding the foregoing, if the Company determines
         that the Executive is in breach of any of the provisions contained in
         Paragraph 7 of this Agreement or any of the provisions contained in
         Section 5.2 of the Purchase Agreement during the period over which the
         Severance Amount is being paid, then all further payments of the
         Severance Amount shall immediately cease. Furthermore, in the event
         Executive terminates his employment for Good Reason, he shall be
         entitled to the Severance Amount only if he provides the Notice of
         Termination within sixty (60) days after the occurrence of the event or
         events which constitute such Good Reason.

                           (ii)     Notwithstanding anything to the contrary in
         any applicable option agreement or stock-based award agreement, upon a
         Change in Control, all stock options and other stock-based awards
         granted to Executive by the Company shall immediately accelerate and
         become exercisable or non-forfeitable as of the effective date of such
         Change in Control. Executive shall also be entitled to any other rights
         and benefits with respect to stock-related awards, to the extent and
         upon the terms provided in the employee stock option or incentive plan
         or any agreement or other instrument attendant thereto pursuant to
         which such options or awards were granted. Notwithstanding the
         foregoing, if the Company determines that the Executive is in breach of
         any of the provisions contained in Paragraph 7 of this Agreement or any
         of the provisions contained in Section 5.2 of the Purchase Agreement,
         then all stock options held by the Executive shall immediately
         terminate and be of no further force and effect.

                           (iii)    The Company shall, for a period of one (1)
         year commencing on the Date of Termination, pay such health and dental
         insurance premiums as may be necessary to allow Executive and
         Executive's spouse and dependents to continue to

                                       7
<PAGE>

         receive health and dental insurance coverage substantially similar to
         the coverage they received prior to the Date of Termination.
         Notwithstanding the foregoing, if the Company determines that the
         Executive is in breach of any of the provisions contained in Paragraph
         7 of this Agreement or any of the provisions contained in Section 5.2
         of the Purchase Agreement during the period over which payments are
         being made pursuant to this Subparagraph 6(a)(iii), then all further
         payments under this Subparagraph 6(a)(iii) shall immediately cease.

                  (b)      DEFINITIONS. For purposes of this Paragraph 6, the
         following terms shall have the following meanings:

         "CHANGE IN CONTROL" shall mean any of the following:

                           (a)      any "person," as such term is used in
                           Sections 13(d) and 14(d) of the Securities Exchange
                           Act of 1934, as amended (the "Act") (other than the
                           Company, any of its subsidiaries, or any trustee,
                           fiduciary or other person or entity holding
                           securities under any Employee Benefit Plan or trust
                           of the Company or any of its subsidiaries), together
                           with all "affiliates" and "associates" (as such terms
                           are defined in Rule 12b-2 under the Act) of such
                           person, shall become the "beneficial owner" (as such
                           term is defined in Rule 13d-3 under the Act),
                           directly or indirectly, of securities of the Company
                           representing forty percent (40%) or more of either
                           (A) the combined voting power of the Company's then
                           outstanding securities having the right to vote in an
                           election of the Company's Board of Directors ("Voting
                           Securities"), or (B) the then outstanding shares of
                           the Company's common stock, par value $0.01 per share
                           ("Common Stock") (other than as a result of an
                           acquisition of securities directly from the Company);
                           or

                           (b)      persons who, as of the Commencement Date,
                           constitute the Company's Board of Directors (the
                           "Incumbent Directors") cease for any reason,
                           including, without limitation, as a result of a
                           tender offer, proxy contest, merger or similar
                           transaction, to constitute at least a majority of the
                           Board of Directors, provided that any person becoming
                           a director of the Company subsequent to the
                           Commencement Date shall be considered an Incumbent
                           Director if such person's election was approved by,
                           or such person was nominated for election by, a vote
                           of at least a majority of the Incumbent Directors;
                           but provided further, that any such person whose
                           initial assumption of office is in connection with an
                           actual or threatened election contest relating to the
                           election of members of the Board of Directors or
                           other actual or threatened solicitation of proxies or
                           consents by or on behalf of a person other than the
                           Board of Directors, including by reason of agreement
                           intended to avoid or settle any such actual or
                           threatened contest or solicitation, shall not be
                           considered an Incumbent Director; or

                                       8
<PAGE>

                           (c)      the stockholders of the Company shall
                           approve (A) any consolidation or merger of the
                           Company where the stockholders of the Company,
                           immediately prior to the consolidation or merger,
                           would not, immediately after the consolidation or
                           merger, beneficially own (as such term is defined in
                           Rule 13d-3 under the Act), directly or indirectly,
                           shares representing in the aggregate more than fifty
                           percent (50%) of the voting shares of the company
                           issuing cash or securities in the consolidation or
                           merger (or of its ultimate parent corporation, if
                           any), (B) any sale, lease, exchange or other transfer
                           (in one transaction or a series of transactions
                           contemplated or arranged by any party as a single
                           plan) of all or substantially all of the assets of
                           the Company, or (C) any plan or proposal for the
                           liquidation or dissolution of the Company.

         Notwithstanding the foregoing, a "Change in Control" shall not be
deemed to have occurred for purposes of the foregoing clause (a) solely as the
result of an acquisition of securities by the Company which, by reducing the
number of shares of Common Stock or other Voting Securities outstanding,
increases the proportionate number of shares beneficially owned by any person to
forty percent (40%) or more of either (A) the combined voting power of all of
the then outstanding Voting Securities or (B) the outstanding shares of Common
Stock; provided, however, that if any person referred to in this sentence shall
thereafter become the beneficial owner of any additional shares of Voting
Securities or Common Stock (other than pursuant to a stock split, stock
dividend, or similar transaction or as a result of an acquisition of securities
directly from the Company) and immediately thereafter beneficially owns forty
percent (40%) or more of either (A) the combined voting power of all of the then
outstanding Voting Securities or (B) the outstanding shares of Common Stock,
then a "Change in Control" shall be deemed to have occurred for purposes of the
foregoing clause (a).

         "GOOD REASON" shall mean any of the following:

                           (a)      a substantial diminution or other
                           substantive adverse change, not consented to by
                           Executive, in the nature or scope of Executive's
                           responsibilities, authorities, powers, functions or
                           duties;

                           (b)      any removal, during the Period of
                           Employment, from Executive of his title as set forth
                           in Paragraph 2 of this Agreement;

                           (c)      an involuntary reduction in Executive's Base
                           Salary except for across-the-board reductions
                           similarly affecting all or substantially all
                           management employees;

                           (d)      a breach by the Company of any of its other
                           material obligations under this Agreement and the
                           failure of the Company to cure such breach within
                           thirty (30) days after written notice thereof by
                           Executive;

                                       9
<PAGE>

                           (e)      the involuntary relocation of the Company's
                           offices at which Executive is principally employed or
                           the involuntary relocation of the offices of
                           Executive's primary workgroup to a location more than
                           thirty (30) miles from such offices, or the
                           requirement by the Company that Executive be based
                           anywhere other than the Company's offices at such
                           location on an extended basis, except for required
                           travel on the Company's business to an extent
                           substantially consistent with Executive's business
                           travel obligations; or

                           (f)      the failure of the Company to obtain the
                           agreement from any successor to the Company to assume
                           and agree to perform this Agreement as required by
                           Paragraph 9.

         7.       CONFIDENTIALITY, ASSIGNMENT OF INVENTIONS, ETC.

                  (a)      Executive acknowledges that, in order for him to
         perform his duties properly, the Company will from time to time entrust
         Executive with certain trade secrets and confidential information in
         relation to the Company and the Company's activities (the "Confidential
         Information"). Such Confidential Information may be in tangible or
         intangible form. The Confidential Information includes, but is not
         limited to, source code; object code; operational and functional
         features and limitations of the Company's software; the Company's
         research and development plans and activities; the Company's
         manufacturing and production plans and activities; the prices, terms
         and conditions of the Company's contracts with its customers; the
         identities, needs and requirements of the Company's customers; the
         Company's pricing policies and price lists; the Company's business
         plans and strategies; the Company's marketing plans and strategies; and
         personnel information and financial information regarding the Company.
         Executive further acknowledges that the development or acquisition of
         such Confidential Information is the result of great effort and expense
         by the Company and the Confidential Information is critical to the
         survival and success of the Company and that the unauthorized
         disclosure or use of the Confidential Information would cause the
         Company irreparable harm.

                  (b)      Executive agrees that during the Period of Employment
         with the Company and thereafter, he will not disclose the Confidential
         Information or use it in any way, except on behalf of the Company,
         whether or not such Confidential Information is produced by Executive's
         own efforts. This undertaking will not apply to any Confidential
         Information which is (i) publicly known through no unauthorized act of
         Executive, (ii) approved by the Company for disclosure, or (iii) the
         subject matter of a lawful request or subpoena by and within the
         authority of a court or governmental agency or other body. Executive
         further agrees, upon termination of his employment for any reason, to
         deliver to Company on or prior to his last day of employment, all
         Confidential Information (in whatever form, including notes, drawings,
         files, computer records or other means, and wherever located, including
         Executive's office, home, personal computer or internet web

                                       10

         site), whether or not such Confidential Information was produced by
         Executive's own efforts, and to refrain from making, retaining,
         destroying or distributing copies thereof.

                  (c)      Any invention, discovery, development, improvement,
         procedure, writing, work or design (collectively referred to herein as
         "invention or discovery") that relates to any aspect of the business of
         the Company, or results from any work performed on the premises of the
         Company or by use of the facilities, equipment or services of other
         employees of the Company, whether patentable, copyrightable or not and
         that is made or discovered by Executive individually or jointly with
         any other person or persons during the Period of Employment, whether on
         Company business hours or not, shall be promptly disclosed to the
         Company. All such inventions and discoveries shall be the sole property
         of the Company. Any such invention or discovery shall be considered
         work made for hire. Executive hereby assigns to the Company all right,
         title and interest to any such invention or discovery.

                  (d)      In the event that any such invention or discovery
         shall be determined by the Company in its sole discretion to be of a
         patentable nature or to contain material subject to copyright or
         trademark protection, Executive, whether or not then employed by the
         Company, will assist the Company or its nominee to obtain, maintain and
         enforce copyrights, trademarks or patents in the United States of
         America and in any and all countries so designated, all at the expense
         of the Company. Executive will supply evidence, give testimony, sign
         all papers and do all other legal and proper things which Executive or
         its nominees may deem necessary for obtaining, maintaining and
         enforcing its copyrights, trademarks and patents and for vesting in
         Executive or its nominee full title thereto. Executive hereby
         irrevocably appoints the Company to be his attorney in fact and, in his
         name and on his behalf, to execute all such instruments and take all
         other actions and generally to use his name for the purpose of giving
         to the Company the full benefit of the provisions of this Subparagraph.

                  (e)      The assignment of any invention or discovery under
         this Paragraph 7 shall not extend to inventions or discoveries, the
         assignment of which is prohibited by California Labor Code Paragraph
         2870, which provides as follows:

                           (i)      Any provision in an employment agreement
         which provides that an employee shall assign, or offer to assign, any
         of his or her rights in an invention to his or her employer shall not
         apply to an invention that the employee developed entirely on his or
         her own time without using the employer's equipment, supplies,
         facilities, or trade secret information except for those inventions
         that either:

                                    (A)      Relate at the time of conception or
                  reduction to practice of the invention to the employer's
                  business, or actual or demonstrably anticipated research or
                  development of the employer; or

                                    (B)      Result from any work performed by
                  the employee for his employer.

                                       11
<PAGE>

                           (ii)     To the extent a provision in an employment
         agreement purports to require an employee to assign an invention
         otherwise excluded from being required to be assigned under subdivision
         (i), the provision is against the public policy of this state and is
         unenforceable.

                  (f)      Executive agrees, upon request by the Company, or
         termination of his employment for any reason, promptly to deliver to
         the Company all files, computer files or databases, books, documents,
         computer disks or tapes, and other property prepared by or on behalf of
         the Company or purchased with Company funds, and to refrain from
         making, retaining, destroying or distributing copies thereof.

                  (g)      Executive represents and warrants to the Company that
         the execution of this Agreement by him, his performance of his
         obligations hereunder and his employment by the Company will not, with
         or without the giving of notice or the passage of time, conflict with,
         result in the breach or termination of, or constitute default under,
         any agreement to which Executive is party or by which he is or may be
         bound.

                  (h)      The provisions of this Paragraph 7 shall survive the
         termination of the Executive's employment with the Company regardless
         of the manner of such termination, and shall be binding on Executive
         and his heirs, executors and administrators.

                  (i)      Anything herein to the contrary notwithstanding, any
         confidential/proprietary/trade secrets information and inventions
         agreement(s) between Executive AMSI, or any predecessor thereto, will

         shall diminish or modify any obligations Executive owes to the Company
         as set forth in Section 5.2 of the Purchase Agreement.

                  (j)      References in this Paragraph 7 to the "Company" shall

         9.       SUCCESSOR TO COMPANY. The Company shall require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company in a
transaction constituting a Change in Control to expressly to assume and agree to
perform this Agreement to the same extent that the Company would be required to
perform it if no succession had taken place. Failure of the Company to obtain an
assumption of this Agreement at or prior to the effectiveness of any succession
shall be a breach of this Agreement and shall constitute Good Reason if the
Executive elects to terminate employment following such Change in Control.

         10.      MISCELLANEOUS. No provisions of this Agreement may be
modified, waived, or discharged unless such waiver, modification, or discharge
is agreed to in writing and signed by Executive and such officer of the Company

representations, oral or otherwise, express or implied, unless specifically
referred to herein, with respect to the subject matter hereof have been made by
either party which are not set forth expressly in this Agreement. The validity,
interpretation, construction, and performance of this Agreement shall be
governed and construed by and in accordance with the substantive law of
California, excluding, however such laws pertaining to conflict of laws.

         11.      VALIDITY. The invalidity or unenforceability of any provision
or provisions of this Agreement shall not affect the validity or enforceability
of any other provision of this Agreement, which shall remain in full force and
effect.

         12.      COUNTERPARTS. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         13.      ARBITRATION; OTHER DISPUTES. In the event of any dispute or
controversy arising under or in connection with this Agreement, the parties
shall first try in good faith for a period of 30 days to settle such dispute or
controversy by mediation under the applicable rules of the American Arbitration
Association before resorting to arbitration. Following such time period, the
parties will settle any remaining dispute or controversy exclusively by
arbitration in Boston, Massachusetts in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction. Notwithstanding the above,
the Company shall be entitled to seek a restraining order or

injunction in any court of competent jurisdiction to prevent any continuation of
any violation of Paragraph 7 of this Agreement.

         14.      LITIGATION AND REGULATORY COOPERATION. During and after
Executive's employment, Executive shall reasonably cooperate 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 which relate to
events or occurrences that transpired while Executive was employed by the
Company; provided, however, that such cooperation shall not materially and
adversely affect Executive or expose Executive to an increased probability of
civil or criminal litigation. The Company shall also provide Executive with
compensation on an hourly basis (to be derived from his Base Salary) for
requested litigation and regulatory cooperation that occurs after his
termination of employment, and reimburse Executive for all costs and expenses
incurred in connection with his performance under this Paragraph 14, including,
but not limited to, reasonable attorneys' fees and costs.
