                 MOLDFLOW CORPORATION 1997 EQUITY INCENTIVE PLAN

                 Nonstatutory Stock Option Terms And Conditions

      1. Plan Incorporated by Reference. This Option is issued pursuant to the
terms of the Plan and may be amended as provided in the Plan. Capitalized terms
used and not otherwise defined in this certificate have the meanings given to
them in the Plan. This certificate does not set forth all of the terms and
conditions of the Plan, which are incorporated herein by reference. The
Committee administers the Plan and its determinations regarding the operation of
the Plan are final and binding. Copies or the Plan may be obtained upon written
request without charge from the Secretary of the Company.

      2. Option Price. The price to be paid for each share of Common Stock
issued upon exercise of the whole or any part of this Option is the Option Price
set forth on the face of this certificate.

      3. Exercisability Schedule. This Option may be exercised at any time and
from time to time for the number of shares and in accordance with the
exercisability schedule set forth on the face of this certificate, but only for
the purchase of whole shares. This Option may not be exercised as to any shares
after the Expiration Date.

      4. Method of Exercise. To exercise this Option, the Optionholder shall
deliver written notice of exercise to the Company specifying the number or
shares with respect to which the Option is being exercised accompanied by
payment of the Option Price for such shares in cash, by certified check or in
such other form, including shares of Common Stock of the Company valued at their
Fair Market Value on the date of delivery, as the Committee may approve.
Promptly following such notice, the Company will deliver to the Optionholder a
certificate representing the number of shares with respect to which the Option
is being exercised.

      5. Rights as a Stockholder or Employee. The Optionholder shall not have
any rights in respect of shares as to which the Option shall not have been
exercised and payment made as provided above. The Optionholder shall not have
any rights to continued employment by the Company or its Affiliates by virtue of
the grant of this Option.

      6. Recapitalization, Mergers, Etc. As provided in the Plan, in the event
of corporate transactions affecting the Company's outstanding Common Stock, the
Committee shall equitably adjust the number and kind of shares subject to this
Option and the exercise price hereunder or make provision for a cash payment. If
such transaction involves a consolidation or merger of the Company with another
entity, the sale or exchange of all or substantially all of the assets of the
Company or a reorganization or liquidation of the Company, then in lieu of the
foregoing, the Committee may upon written notice to the Optionholder provide
that this Option shall terminate on a date not less than 20 days after the date
of such notice unless theretofore exercised. In connection with such notice, the
Committee may in its discretion accelerate or waive any deferred exercise
period.

      7. Option Not Transferable. This Option is not transferable by the
Optionholder otherwise than by will or the laws of descent and distribution, and
is exercisable, during the Optionholder's lifetime, only by the Optionholder.
The naming of a Designated Beneficiary does not constitute a transfer.

      8. Exercise of Option After Termination of Employment. If the
Optionholder's status as an employee or consultant of (a) the Company, (b) an
Affiliate, or (c) a corporation (or parent or subsidiary corporation of such
corporation) issuing or assuming a stock option in a transaction to which
section 424(a) of the Code applies, is terminated for any reason other than by
disability (within the meaning of section 22(e)(3) of the Code) or death, the
Optionholder may exercise the rights which were available to the Optionholder at
the time of such termination only within one month from the date of termination.
If such status is terminated as a result of disability, such rights may be
exercised within twelve months from the date or termination. Upon the death of
the Optionholder, his or her Designated Beneficiary shall have the right, at any
time within one month after the date of death, to exercise in whole or in part
any rights that were available to the Optionholder at the time of death.
Notwithstanding the foregoing, no rights under this Option may be exercised
after the Expiration Date.

      9. Compliance with Securities Laws. It shall be a condition to the
Optionholder's right to purchase shares of Common Stock hereunder that the
Company may, in its discretion, require (a) that the shares of Common Stock
reserved for issue upon the exercise of this Option shall have been duly listed,
upon official notice of issuance, upon any national securities exchange or
automated quotation system on which the Company's Common Stock may then be
listed or quoted, (b) that either (i) a registration statement under the
Securities Act of 1933 with respect to the shares shall be in effect, or (ii) in
the opinion of counsel for the Company, the proposed purchase shall be exempt
from registration under that Act and the Optionholder shall have made such
undertakings and agreements with the Company as the Company may reasonably
require, and (c) that such other steps, if any, as counsel for the Company shall
consider necessary to comply with any law applicable to the issue of such shares
by the Company shall have been taken by the Company or the Optionholder, or
both. The certificates representing the shares purchased under this Option may
contain such legends as counsel for the Company shall consider necessary to
comply with any applicable law.

      10. Payment of Taxes. The Optionholder shall pay to the Company, or make
provision satisfactory to the Company for payment of, any taxes required by law
to be withheld with respect to the exercise of this Option. The Committee may,
in its discretion, require any other Federal or state taxes imposed on the sale
of the shares to be paid by the Optionholder. In the Committee's discretion,
such tax obligations may be paid in whole or in part in shares of Common Stock,
including shares retained from the exercise of this Option, valued at their Fair
Market Value on the date of delivery. The Company and its Affiliates may, to the
extent permitted by law, deduct any such tax obligations from any payment of any
kind otherwise due to the Optionholder.
