            (i)   specifies the nature of the Executive's failure; and
<PAGE>

            (ii)  advises the Executive that should the failure continue for a
                  period 30 days (or such longer period as has been agreed by
                  the parties) from the date of the service of the notice, his
                  employment may be terminated forthwith;

      (h)   the Executive is prevented from carrying out his duties in a proper
            and business like manner by reason of sickness, ill health or injury

            the Company, has caused a conflict between the Executive's duty to
            the Company and any other duty to which the Executive may be
            subject, directly or indirectly.

      The parties acknowledge and agree that each of the above grounds for
      termination are separate and distinct and shall not operate in any way to
      limit the generality of any other ground or grounds of termination set out
      above, all of which shall have at all times independent operation.

6.2   The notice required for termination in each of the foregoing events is as
      set out below:

      EVENT             NOTICE

      (j)   No period of notice required.

6.3   The Company may elect to make a payment to the Executive in lieu of notice
      provided for in sub-clauses 6.2 or 6.5 and such payment will be the amount
      equal to that proportion of the Executive's then current total
      remuneration attributable to the period of notice (if any). If no period
      of notice is required pursuant to sub-clause 6.2 of this Agreement, no
      payment in lieu of notice is required.

6.4   (a)   The Executive may, upon and only upon having served as an
            employee of the Company pursuant to this Agreement for a period of
            not less than 2 1/2 years, terminate this Agreement by giving the
            Company not less than 6 months written notice of termination.

      (b)   The Company may choose to waive service of the notice period given
            by the Executive pursuant to sub-clause 6.4(a) of this Agreement
            and, in such case, shall, subject to sub-clause 6.4(c) of this
            Agreement, pay the Executive an amount equal to that proportion of
            the Executive's total remuneration attributable to the waived period
            of notice as if the employment had continued during the waived
            period.

      (c)   (i)   If the Executive intends entering into the employment of, or
                  does so enter into the employment of, a Competitor or Customer
                  during the period of written notice of termination given by
                  the Executive pursuant to sub-clause 6.4(a) of this Agreement,
                  then and in that event the Company will not be under any
                  obligation to make any payments to the Executive pursuant to
                  sub-clause 6.4(b) of this Agreement in lieu of such waived
                  period of notice and the Executive must forthwith refund
<PAGE>

                                            10


                  to the Company any moneys paid under that sub-clause by the
                  Company to the Executive.

            (ii)  For the purposes of sub-clause 6.4(c)(i), the phrases
                  `entering into the employment of' and `enter into the
                  employment of' includes being or becoming directly or
                  indirectly a member, shareholder, director, employee,
                  consultant, agent or senior executive in, of, for, to or in
                  respect of (as the case may be) any Person or Persons.

6.5   If during the term of this Agreement there is a change to the Executive's
      employment conditions which, by an objective reasonable standard, is to
      his material detriment, the Executive may at any time during the period of
      3 months after that change, elect to terminate this Agreement and the
      Remuneration Schedule by not less than 3 months written notice to the
      Company.

7.    CONFIDENTIALITY

7.1   The Executive must:

      (a)   not, except as authorised or required by his duties as an employee
            of the Company, reveal to any Person or Persons any of the trade
            secrets, secret or confidential operations, processes or dealings or
            any information concerning the Company's business or the
            organisation, business finances, transactions or affairs of the
            Company which may come to his knowledge during or at any time after

            or indirectly to the Company or its business or may be likely so to
            do.

7.2   Each restriction set out in sub-clause 7.1 will continue to apply after
      the termination of this Agreement without limitation in point of time but
      will cease to apply to information which comes into the public domain
      other than by breach of this Agreement or by any breach of any other duty
      or obligation of confidentiality owed to the Company.

7.3   For the purposes of this clause 7, `Company' includes jointly and
      severally the Company and each Related Corporation of the Company and each
      Associated Entity of the Company.

8.    NON COMPETITION

8.1   In consideration of the employment of the Executive and other valuable
      consideration whether directly or indirectly received by the Executive
      from the Company and to reasonably protect the goodwill and the business
      of the Company, the Executive agrees with the Company that:

      (a)   this clause will have effect as if it were several separate
            covenants and restraints consisting of each separate covenant and
            restraint obtained by the combinations set out in paragraph (b) of
            this sub-clause combined with each separate period of time set out
            in paragraph (c) of this sub-clause and of each such separate
            combination combined with each separate area set out in paragraph
            (d) of this sub-clause and if any of these several separate
            covenants and restraints are or become invalid or unenforceable for
            any reason, then that invalidity or unenforceability will not affect
            the validity or enforceability of any of the other separate
            covenants and restraints;

      (b)   without the prior written consent of the Company, the Executive will
            not, whether directly or indirectly,
<PAGE>

                                            12

            to be paid and provided by the Company to the Executive entirely by
            way of salary; and

      (b)   unless the Principal Agreement is terminated by the Company as a
            result of any act or default of the Executive, other than under
            clause 6.1(d), (h) or (i) $300,000 upon termination of the Principal
            Agreement except that the payment shall be $200,000 if the net
            profit before tax of Moldflow Pty Ltd for the financial year ending
            30 June 1994 is less than $1,900,000. For the purpose of this clause
            the net profit before tax of Moldflow Pty Ltd shall be the amount
            agreed by its auditors to be the net profit before tax and shall be
            calculated in accordance with the same accounting principles
            observed by Moldflow Pty Ltd in preparing its budget for the
            financial year ending 30 June 1994.

      The Company must reimburse all reasonable and proper expenses incurred by
      the Executive in carrying out his duties in accordance with this Schedule
      and the Principal Agreement subject always to the presentation of fully
      supportable claims approved by the Company.

2.2   For the purposes of this Clause, the cost to the Company of any benefits
      provided by the Company to the Executive shall be the actual cost to the
      Company of providing such benefits (as determined by the Company and
      notified to the Executive) and shall include:

      (a)   where the benefits are fringe benefits and are provided to the
            Executive prior to 1 April 1994 - the amount which would be the
            fringe benefits taxable amount (as defined in S.136(1) of the FBT
            Act) if calculated in respect of such benefits increased by the
            burden of Fringe Benefits Tax;

      (b)   where the benefits are fringe benefits and are provided to the
            Executive on or after 1 April 1994 - the amount which would be the
            fringe benefits

            taxable amount (as defined in S.136AA of the FBT Act) if calculated
            in respect of such benefits; or

      (c)   where the benefits are not fringe benefits and the Company is not
            entitled to an allowable deduction under the Income Tax Assessment
            Act in respect of such benefits - the burden of non deductibility.'

2.3   Where by the last day of a Remuneration Period the total cost to the
      Company of the benefits provided to the Executive does not equal the cost
      of the benefits agreed by the Company to be provided to the Executive for
      that Remuneration Period:

      (a)   the balance then remaining to be provided to the Executive must be
            provided in such manner as the parties agree or failing such
            agreement in the form of additional salary; and

      (b)   if the employment of the Executive is not then ceasing, the cost to
            the Company of any excess benefits provided during the remuneration
            period shall be deducted from the amount of the Total Remuneration
            to be paid or provided for the following Remuneration Period, or if
            the employment of the Executive has ceased an amount equal to the
            cost to the Company of such excess must be paid forthwith by the
            Executive to the Company.

3.    REVIEW OF REMUNERATION

3.1   The Company agrees that, while the Executive's employment continues under
      the Principal Agreement, for each Remuneration Period it must, at least 28
      days prior to the expiration of such Period, review the level of Total
      Remuneration, and the components of that remuneration, to which the
      Executive shall be entitled in the following Remuneration Period.

3.2   The Company's decision in relation to the level of Total Remuneration for
      the following Remuneration Period pursuant to sub-clause 3.1 of this
      Schedule must be reasonable, and must not be less than the Total
      Remuneration paid during the initial Remuneration Period, but otherwise
      will be final and binding on the Executive.

3.3   The Executive will not be entitled to an increase in Total Remuneration
      otherwise than as a result of a review conducted pursuant to clause 3 of
      this Schedule.

3.4   As soon as is reasonable practicable following the review conducted
      pursuant to this clause by the Company, the Company shall provide to the
      Executive notice in writing of its decision. Where the Executive believes
      it to be appropriate and so notifies the Company, the Company must advise
      the Executive as soon as reasonably possible after the Executive's
      notification of the reasons upon which the decision was based.
