                         EXECUTIVE EMPLOYMENT AGREEMENT

         This EXECUTIVE EMPLOYMENT AGREEMENT ("Agreement") is made as of the
16th day of August 2002 between MOLDFLOW CORPORATION, a Delaware corporation
(referred to herein as including all of its subsidiaries, including MPL, the
"Company"), and A. ROLAND THOMAS ("Executive").

         WHEREAS, the Company and the Executive are party to an Executive
Employment Agreement dated as of March 20, 2000, as amended on September 22,
2000 (the "Prior Agreement"); and

         WHEREAS, the Company desires to continue to employ Executive and
Executive desires to continue to be employed by the Company on the terms
contained herein which shall supercede all of the terms and conditions of the
Prior Agreement.

         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 6 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 President and Chief Executive Officer and shall have such duties as may
from time to time be prescribed by 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 $230,000. Executive's base salary shall be redetermined
annually by 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 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 Board or
a Committee thereof shall determine from time to time for senior executives of
the Company. 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 on a pro rata basis during
  the fiscal year, and Executive shall also be entitled to all paid holidays
  given by the Company to its executives. Executive shall be entitled to
  additional vacation based on any policy of the Company that provides for
  additional vacation based on years of service or other criteria.

         (c) ADDITIONAL BENEFITS. During the Period of Employment the Company
will reimburse the Executive for the cost of a supplemental policy of long-term
disability insurance for the Executive.

                                       1

         (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.

         (e) STATUS OF AUSTRALIAN BENEFITS AND ACCRUED ENTITLEMENTS. Pursuant to
the terms of the Prior Agreement, Executive was relocated by the Company from
employment with the Company's subsidiary, Moldflow Pty. Ltd. (MPL"), an
Australian company, to the Company's headquarters in the United States. As part
of such relocation, Executive became an employee of the Company on September 22,
2000 and ceased to be an employee of MPL on such date. In order to finalize
Executive's relationship with MPL, the parties agree as follows:

              (i)  Within thirty (30) days of the date of this Agreement, MPL
                   will pay to Executive a lump sum of A$63,339, less any tax
                   payable, in full and final settlement of Executive's accrued
                   annual leave while an employee at MPL. Executive and the
                   Company agree that Executive shall have no further rights to
                   accrue annual leave at MPL.

              (ii) Within thirty (30) days of the date of this Agreement, MPL
                   will pay to Executive a lump sum of A$77,077, less any tax
                   payable, in full and final settlement of Executive's accrued
                   long service leave which accrued to Executive while an
                   employee of MPL pursuant to the Long Service Leave Act 1992
                   (Vic) (the "LSL Act".) Executive and the Company agree that
                   Executive shall have no further rights to accrue long service
                   leave at MPL.

              (iii) Executive and Company agree that no further superannuation
                   contributions will be made for Mr. Thomas by MPL and MPL's
                   legal requirement to make superannuation contributions on
                   behalf of Mr. Thomas ceased on September 22, 2000 when he
                   became an employee of the Company.

              (iv) The Company will reimburse Executive for Australian personal
                   income taxes that Executive may be required to pay in
                   connection with the disposition of the shares of Moldflow
                   stock held by Thomas Investments, provided that such
                   reimbursement shall not exceed 25% of the difference between
                   the cost basis of the shares and $4.50 per share.

4. UNAUTHORIZED DISCLOSURE.

         Executive acknowledges that in the course of his employment with the
Company (and, if applicable, its predecessors), he has and will become
acquainted with the Company's business affairs, information, trade secrets, and
other matters which are of a proprietary or confidential nature, including but
not limited to the Company's and its affiliates' and predecessors' operations,
business opportunities, price and cost information, finance, customer
information, product development information, business plans, various sales
techniques, manuals, letters, notebooks, procedures, reports, products,
processes, services, and other confidential information and knowledge
(collectively the "Confidential Information") concerning the Company's and its
affiliates' and predecessors' business. Executive understands and acknowledges
that such Confidential Information is confidential, and he agrees not to
disclose such Confidential Information to anyone outside the Company except to
the extent that (i) Executive deems such disclosure or use reasonably necessary
or appropriate in connection with performing his duties on behalf of the
Company; (ii) Executive is required by order of a court of competent
jurisdiction (by subpoena or similar process) to disclose or discuss any
Confidential Information, provided that in such case, Executive shall promptly
inform the Company of such event, shall cooperate with the Company in attempting
to obtain a protective order or to otherwise restrict such disclosure, and shall
only disclose Confidential Information to the minimum extent necessary to comply
with any such court order; or (iii) such Confidential Information becomes
generally known to and available for use in the Company's industry, other than
as a result of any action or inaction by Executive. Executive further agrees
that he will not during employment and/or at any time thereafter use such
Confidential Information in competing, directly or indirectly, with the Company.
At such time as Executive shall cease to be employed by the Company, he will
immediately turn over to the Company all Confidential Information, including
papers, documents, writings, electronically stored information, other property,
and all copies of them provided to or created by him during the course of his
employment with the Company. The foregoing provisions shall be binding upon
Executive's heirs, successors, and legal representatives and shall survive the
termination of this Agreement for any reason.

5. COVENANT NOT TO COMPETE.

        In consideration for Executive's employment by the Company under the
terms provided in this Agreement and as a means to aid in the performance and
enforcement of the terms of the provisions of Paragraph 4, Executive agrees
that:

         (a) during the Period of Employment and for a period of twelve (12)
months thereafter, regardless of the reason for termination of employment,
Executive will not, directly or indirectly, as an owner, director, principal,
agent, officer, employee, partner, consultant, servant, or otherwise, carry on,
operate, manage, control, or become involved in any manner with any business,
operation, corporation, partnership, association, agency, or other person or
entity which is engaged in a business that is directly competitive with any of
the Company's products which are produced or in development by the Company as of
the date of Executive's termination of employment, anywhere in the world;
provided, however, that the foregoing shall not prohibit Executive from owning
up to one percent (1%) of the outstanding stock of a publicly held company
engaged in activities competitive with that of the Company; and

         (b) during the term of Executive's employment with the Company and for
a period of twelve (12) months thereafter, regardless of the reason for
termination of employment, Executive will not directly or indirectly solicit or
induce any present or future employee of the Company or any affiliate of the
Company to accept employment with Executive or with any business, operation,
corporation, partnership, association, agency, or other person or entity with
which Executive may be associated, and Executive will not knowingly employ or
cause any business, operation, corporation, partnership, association, agency, or
other person or entity with which Executive may be associated to employ any
present or future employee of the Company without providing the Company with ten
(10) days' prior written notice of such proposed employment.

         Should Executive violate any of the provisions of this Paragraph, then
in addition to all other rights and remedies available to the Company at law or
in equity, the duration of this covenant shall automatically be extended for the
period of time from which Executive began such violation until he permanently
ceases such violation.

6. TERMINATION. Except for termination as specified in Subparagraph 6(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. Upon termination from the Company for any reason, and if so
requested, Executive agrees to deliver his resignation as a director of the
Company or any of its subsidiaries or affiliates upon the request of the
Chairman of the Board of Directors. 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 Board. For
purposes of this Agreement, "Cause" shall mean: (A) conduct by Executive
constituting a material act of willful misconduct in connection with the
performance of his duties; (B) criminal or civil conviction of Executive,
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, 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 and the reasons for the dissatisfaction from the
Board; or (D) a breach by Executive of any of the provisions contained in
Paragraphs 4 and 5 of this Agreement.

                                       3

         (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
6(c) or result from the death or disability of the Executive under Subparagraph
6(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,
including but not limited to Good Reason. If Executive provides notice to the
Company under Paragraph 1 that he does not wish to extend the Period of
Employment, such action shall be deemed a voluntary termination by Executive and
one without Good Reason. For purposes of this Agreement, "Good Reason" shall
mean: (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; (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 and except for any
expatriate assignments proposed by the Company and agreed to by Executive; 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
10.

         (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 6(b) or under
Subparagraph 6(c), the date on which Notice of Termination is given; (C) if
Executive's employment is terminated by the Company under Subparagraph 6(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
6(e), thirty (30) days after the date on which a Notice of Termination is given,
unless the Company cures the Good Reason event prompting the Executive to issue
a Notice of Termination.

7. 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 death, 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 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 death of Executive 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 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, if any, substantially similar to coverage they received from
the Company or MPL

                                       4

<PAGE>

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 or arrangement. 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 accrued and unpaid Base Salary and 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) until Executive's employment is terminated due to disability
in accordance with Subparagraph 6(b) or until Executive terminates his
employment in accordance with Subparagraph 6(e), whichever first occurs. 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 from the
Company prior to the Date of Termination, if any.

         (c) If Executive's employment is terminated by Executive other than for
Good Reason as provided in Subparagraph 6(e), then the Company shall, through
the Date of Termination, pay Executive his accrued and unpaid Base Salary 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 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.

         (d) If Executive terminates his employment for Good Reason as provided
in Subparagraph 6(e) or if Executive's employment is terminated by the Company
without Cause as provided in Subparagraph 6(d), then the Company shall, through
the Date of Termination, pay Executive his accrued and unpaid Base Salary 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 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"). 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 12 months following the Date of
         Termination. Notwithstanding the foregoing, if the Executive breaches
         any of the provisions contained in Paragraphs 4 and 5 of this Agreement
         during the period over which the Termination Amount is being paid, then
         all further payments of the Termination Amount shall immediately
         cease.

                                       5

<PAGE>

                  (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 Executive. All
         other stock-based grants and awards held by Executive shall be canceled
         upon the Termination Date in accordance with their terms.

                  (iii) In addition to any other benefits to which Executive may
         be entitled in accordance with the Company's then existing severance
         policies, 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 from the Company prior
         to the Date of Termination.

                  (iv) In addition to any other benefits to which Executive may
         be entitled, at any time within 12 months following the Date of
         Termination, the Executive may notify the Company that he desires to be
         relocated to Australia. If Executive provides such notice to the
         Company, then the Company will either directly pay or reimburse the
         Executive for the real estate commission actually paid upon the sale of
         his primary US residence, the other closing costs associated with such
         sale, the reasonable travel and moving expenses necessary to relocate
         the Executive, his spouse, his family, his household goods and one
         vehicle to Australia. In addition, the Company will reimburse the
         Executive for any required stamp duty payable in Australia with respect
         to such relocation. The Executive acknowledges that the Company, MPL
         and its related corporations and entities are not required to provide
         the Executive with any form of employment or engagement with MPL if
         Executive is relocated to Australia, unless the parties expressly agree
         otherwise.

         (e) If Executive's employment is terminated by the Company for Cause as
provided in Subparagraph 6(c), then the Company shall, through the Date of
Termination, pay Executive his accrued and unpaid Base Salary 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 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
Termination Date in accordance with their terms.

         (f) Nothing contained in the foregoing Subparagraphs 7(a) through 7(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.

8. CHANGE IN CONTROL BENEFIT. Upon a Change of Control of the Company the
following provisions shall apply in lieu of, and expressly supersede, the
provisions of Subparagraph 7(d).

         (a)      CHANGE IN CONTROL.

                  (i) In the event that within 12 months following a Change of
         Control the Executive terminates his employment for Good Reason 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 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 of
         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

                                       6

<PAGE>

         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 18 months following the Date of
         Termination. For purposes of this Agreement, "Base Salary" shall mean
         the annual Base Salary in effect on the Date of Termination.
         Notwithstanding the foregoing, if the Executive breaches any of the
         provisions contained in Paragraphs 4 and 5 of this Agreement then all
         further payments of the Severance Amount shall immediately cease.
         Furthermore, in the event Executive terminates his employment for Good
         Reason as provided in Subparagraph 6(e), he shall be entitled to the
         Severance Amount only if he provides the Notice of Termination provided
         for in Subparagraph 6(a) within sixty (60) days after the occurrence of
         the event or events which constitute such Good Reason as specified in
         Subparagraph 6(e); and

                  (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; and

                  (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, Executive's
         spouse and dependents to continue to receive health and dental
         insurance coverage substantially similar to the coverage they received
         prior to the Date of Termination.

                  (iv) In addition to any other benefits to which Executive may
         be entitled, at any time within 12 months following the Date of
         Termination, the Executive may notify the Company, or its successor,
         that he desires to be relocated to Australia. If Executive provides
         such notice to the Company, then the Company will either directly pay
         or reimburse the Executive for the real estate commission actually paid
         upon the sale of his primary US residence, the other closing costs
         associated with such sale, the reasonable travel and moving expenses
         necessary to relocate the Executive, his spouse, his family, his
         household goods and one vehicle to Australia. In addition, the Company
         will reimburse the Executive for any required stamp duty payable in
         Australia with respect to such relocation. The Executive acknowledges
         that the Company, MPL and its related corporations and entities are not
         required to provide the Executive with any form of employment or
         engagement with MPL if the Executive is relocated to Australia, unless
         the parties expressly agree otherwise.

         (b)      GROSS UP PAYMENT.

                  (i) Anything in this Agreement to the contrary
         notwithstanding, in the event it shall be determined that any
         compensation, payment or distribution by the Company to or for the
         benefit of Executive, whether paid or payable or distributed or
         distributable pursuant to the terms of this Agreement or otherwise (the
         "Severance Payments"), would be subject to the excise tax imposed by
         Section 4999 of the Internal Revenue Code of 1986, as amended (the
         "Code"), or any interest or penalties are incurred by Executive with
         respect to such excise tax (such excise tax, together with any such
         interest and penalties, are hereinafter collectively referred to as the
         "Excise Tax"), then Executive shall be entitled to receive an
         additional payment (a "Gross-Up Payment") such that the net amount
         retained by Executive, after deduction of any Excise Tax on the
         Severance Payments, any Federal, state, and local income tax,
         employment tax and Excise Tax upon the payment provided by this
         subsection, and any interest and/or penalties assessed with respect to
         such Excise Tax, shall be equal to the Severance Payments.

                  (ii) Subject to the provisions of Subparagraph 8(b)(iii), all
         determinations required to be made under this Subparagraph 8(b)(ii),
         including whether a Gross-Up Payment is required and the amount of such
         Gross-Up Payment, shall be made by PriceWaterhouseCoopers or any other
         nationally recognized accounting firm selected by the Company (the
         "Accounting Firm"), which shall provide detailed supporting
         calculations both to the Company and Executive within fifteen (15)
         business days of the Date of

                                       7

<PAGE>

         Termination, if applicable, or at such earlier time as is reasonably
         requested by the Company or Executive. For purposes of determining the
         amount of the Gross-Up Payment, Executive shall be deemed to pay
         federal income taxes at the highest marginal rate of federal income
         taxation applicable to individuals for the calendar year in which the
         Gross-Up Payment is to be made, and state and local income taxes at the
         highest marginal rates of individual taxation in the state and locality
         of Executive's residence on the Date of Termination, net of the maximum
         reduction in federal income taxes which could be obtained from
         deduction of such state and local taxes. The initial Gross-Up Payment,
         if any, as determined pursuant to this Subparagraph 8(b)(ii), shall be
         paid to Executive within five (5) days of the receipt of the Accounting
         Firm's determination. If the Accounting Firm determines that no Excise
         Tax is payable by Executive, the Accounting Firm shall be required to
         (A) conclude that either (I) there has not occurred a change in the
         ownership or effective control of the Company or a change in the
         ownership of a substantial portion of the assets of the Company (as
         such terms are defined in Section 280G of the Code) or (II) no portion
         of the Severance Payments constitutes "parachute payments" (within the
         meaning of said Section 280G), in either case on the basis of
         "substantial authority" (within the meaning of Treas. Reg. Section
         1.6661-3) and (B) provide an opinion to that effect to both the Company
         and the Executive, including the reasons therefor and an opinion that
         Executive has substantial authority not to report any Excise Tax on his
         federal tax return. Any determination by the Accounting Firm shall be
         binding upon the Company and Executive. As a result of the uncertainty
         in the application of Section 4999 of the Code at the time of the
         initial determination by the Accounting Firm hereunder, it is possible
         that Gross-Up Payments which will not have been made by the Company
         should have been made (an "Underpayment"). In the event that the
         Company exhausts its remedies pursuant to Subparagraph 8(b)(iii) and
         Executive thereafter is required to make a payment of any Excise Tax,
         the Accounting Firm shall determine the amount of the Underpayment that
         has occurred, consistent with the calculations required to be made
         hereunder, and any such Underpayment, and any interest and penalties
         imposed on the Underpayment and required to be paid by Executive in
         connection with the proceedings described in Subparagraph 8(b)(iii),
         shall be promptly paid by the Company to or for the benefit of
         Executive.

                  (iii) Executive shall notify the Company in writing of any
         claim by the Internal Revenue Service that, if successful, would
         require the payment by the Company of the Gross-up Payment. Such
         notification shall be given as soon as practicable but no later than
         ten (10) business days after Executive knows of such claim and shall
         apprise the Company of the nature of such claim and the date on which
         such claim is requested to be paid. Executive shall not pay such claim
         prior to the expiration of the 30-day period following the date on
         which he gives such notice to the Company (or such shorter period
         ending on the date that any payment of taxes with respect to such claim
         is due). If the Company notifies Executive in writing prior to the
         expiration of such period that it desires to contest such claim,
         provided that the Company has set aside adequate reserves to cover the
         Underpayment and any interest and penalties thereon that may accrue,
         Executive shall:

                            (A) give the Company any information reasonably
                  requested by the Company relating to such claim,

                           (B) take such action in connection with contesting
                  such claim as the Company shall reasonably request in writing
                  from time to time, including, without limitation, accepting
                  legal representation with respect to such claim by an attorney
                  selected by the Company,

                            (C) cooperate with the Company in good faith in
                  order to effectively contest such claim, and

                            (D) permit the Company to participate in any
                  proceedings relating to such claim; provided, however, that
                  the Company shall bear and pay directly all costs and expenses
                  (including additional interest and penalties) incurred in
                  connection with such contest and shall indemnify and hold
                  Executive harmless, on an after-tax basis, for any Excise Tax
                  or income tax, including interest

                                       8

<PAGE>

                  and penalties with respect thereto, imposed as a result of
                  such representation and payment of costs and expenses. Without
                  limitation on the foregoing provisions of this Subparagraph
                  8(b)(iii), the Company shall control all proceedings taken in
                  connection with such contest and, at its sole option, may
                  pursue or forego any and all administrative appeals,
                  proceedings, hearings and conferences with the taxing
                  authority in respect of such claim and may, at its sole
                  option, either direct Executive to pay the tax claimed and sue
                  for a refund or contest the claim in any permissible manner,
                  and Executive agrees to prosecute such contest to a
                  determination before any administrative tribunal, in a court
                  of initial jurisdiction and in one or more appellate courts,
                  as the Company shall determine; provided, however, that if the
                  Company directs Executive to pay such claim and sue for a
                  refund, the Company shall advance the amount of such payment
                  to Executive on an interest-free basis and shall indemnify and
                  hold Executive harmless, on an after-tax basis, from any
                  Excise Tax or income tax, including interest or penalties with
                  respect thereto, imposed with respect to such advance or with
                  respect to any imputed income with respect to such advance;
                  and further provided that any extension of the statute of
                  limitations relating to payment of taxes for the taxable year
                  of Executive with respect to which such contested amount is
                  claimed to be due is limited solely to such contested amount.
                  Furthermore, the Company's control of the contest shall be
                  limited to issues with respect to which a Gross-Up Payment
                  would be payable hereunder and Executive shall be entitled to
                  settle or contest, as the case may be, any other issues raised
                  by the Internal Revenue Service or any other taxing authority.

                  (iv) If, after the receipt by Executive of an amount advanced
         by the Company pursuant to Subparagraph 8(b)(iii), Executive becomes
         entitled to receive any refund with respect to such claim, Executive
         shall (subject to the Company's complying with the requirements of
         Subparagraph 8(b)(iii)) promptly pay to the Company the amount of such
         refund (together with any interest paid or credited thereon after taxes
         applicable thereto). If, after the receipt by Executive of an amount
         advanced by the Company pursuant to Subparagraph 8(b)(iii), a
         determination is made that Executive shall not be entitled to any
         refund with respect to such claim and the Company does not notify
         Executive in writing of its intent to contest such denial of refund
         prior to the expiration of 30 days after such determination, then such
         advance shall be forgiven and shall not be required to be repaid and
         the amount of such advance shall offset, to the extent thereof, the
         amount of Gross-Up Payment required to be paid.

         (c) DEFINITIONS. For purposes of this Paragraph 8, 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 ("Voting
         Securities") or (B) the then outstanding shares of 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 (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, provided that any

                                        9

<PAGE>

         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 or other actual or
         threatened solicitation of proxies or consents by or on behalf of a
         person other than the Board, 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

                  (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 of 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) 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) Common Stock, then a "Change of Control" shall be deemed to have occurred
for purposes of the foregoing clause (a).

9. NOTICE. For purposes of this Agreement, notices and all other communications
provided for in the Agreement shall be in writing and shall be deemed to have
been duly given when delivered or sent by recognized overnight carrier,

or to such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

10. 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 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

                                       10

<PAGE>

effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if the Executive elects to terminate employment.

11. 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 as may be
specifically designated by the Board. No agreements or 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. This Agreement shall expressly
supercede and replace the Prior Agreement and any other employment agreements,
arrangements and/or understandings between the Executive, the Company, MPL or
any other related corporation or entity. The validity, interpretation,
construction and performance of this Agreement shall be governed by the laws of
the Commonwealth of Massachusetts (without regard to principles of conflicts of
laws).

12. 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.

13. 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.

14. 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 4 or 5
hereof.

15. 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 15, including, but not limited to, reasonable
attorneys' fees and costs.

                           LOAN MODIFICATION AGREEMENT

       This Loan Modification Agreement is entered into as of June 11, 2002, by
and between Moldflow Corporation (the "Borrower") and Silicon Valley Bank, a
California-chartered bank doing business in Massachusetts under the name
"Silicon Valley East" ("Bank").

1. DESCRIPTION OF EXISTING OBLIGATIONS: Among other Obligations which may be
owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among other
documents, a Loan Agreement, dated November 13, 2001, as may be amended from
time to time, (the "Loan Agreement"). The Loan Agreement provides for, among
other things, a Committed Line in the original principal amount of Five Million
Dollars ($5,000,000). Defined terms used but not otherwise defined herein shall
have the same meanings as set forth in the Loan Agreement.

Hereinafter, all indebtedness owing by Borrower to Bank shall be referred to as
the "Obligations."

2. Hereinafter, all other documents evidencing or securing the Obligations shall
be referred to as the "Existing Loan Documents".

3. DESCRIPTION OF CHANGE IN TERMS.

       A. MODIFICATION(S) TO LOAN AGREEMENT.

            1.   The defined term of "Profitability" under Section 5.7 entitled
                 "Financial Covenants" is hereby amended in part to read as
                 follows:

                   Profitability shall be defined as the Borrower's net income
                   after taxes, but prior to depreciation, amortization and
                   non-cash restructuring expenses. For purposes of this
                   covenant, restructuring expenses shall be deducted from net
                   profit when cash payments are made in respect of such
                   expenses.

4. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

5. NO DEFENSES OF BORROWER. Borrower agrees that, as of this date, it has no
defenses against paying the Obligations.

6. CONTINUING VALIDITY. Borrower understands and agrees that in modifying the
existing Obligations, Bank is relying upon Borrower's representations,
warranties, and agreements, as set forth in the Existing Loan Documents. Except
as expressly modified pursuant to this Loan Modification Agreement, the terms of
the Existing Loan Documents remain unchanged and in full force and effect.
Bank's agreement to modifications to the existing Obligations pursuant to this
Loan Modification Agreement in no way shall obligate Bank to make any future
modifications to the Obligations. Nothing in this Loan Modification Agreement
shall constitute a satisfaction of the Obligations. It is the intention of Bank
and Borrower to retain as liable parties all makers and endorsers of Existing
Loan Documents, unless the party is expressly released by Bank in writing.
Unless expressly released herein, no maker, endorser, or guarantor will be
released by virtue of this Loan Modification Agreement. The terms of this
Paragraph apply not only to this Loan Modification Agreement, but also to all
