  under file number 333-46162 (the &#147;Prior Registration Statement&#148;) identifying shares to be
  registered in connection with the Plan. In addition, Section 3(a) of the Plan provides that the
  maximum number of shares of Common Stock reserved for issuance under the Plan shall be increased,
  as of each June&nbsp;30 and December&nbsp;31 following the closing of the Registrant&#146;s initial public
  offering, by an additional positive number equal to twenty percent of the shares of Common Stock
  issued by the Registrant during the six-month period then ended (excluding shares issued in the
  Registrant&#146;s initial public offering). During the period from January&nbsp;1, 2007 to December&nbsp;31, 2007
  the Registrant issued an aggregate of 889,247 shares of Common Stock. As a result, the maximum
  number of shares of Common Stock reserved for issuance under the Plan has been increased by 20% of
  889,247, or 177,848 shares. By filing this Registration Statement in accordance with Instruction E
  to Form S-8, the Registrant hereby registers this additional number of shares.

  <DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 1%">(c)&nbsp;Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
  permitted to directors, officers and controlling persons of the Registrant pursuant to the
  foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public policy as expressed in
  the Act and is, therefore, unenforceable. In the event that a claim for indemnification against
  such liabilities (other than the payment by the Registrant of expenses incurred or paid by a
  director, officer or controlling person of the Registrant in the successful defense of any action,
  suit or proceeding) is asserted by such director, officer or controlling person in connection with
  the securities being registered, the Registrant will, unless in the opinion of its counsel the
  matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
  question whether such indemnification by it is against public policy as expressed in the Act and
  will be governed by the final adjudication of such issue.

  This Registration Statement covers shares of Common Stock, par value $.01 per share (the
  "Common Stock"), of Moldflow Corporation (the "Registrant") which may be offered or sold
  pursuant to the Moldflow Corporation 2000 Stock Option and Incentive Plan, as amended (the
  "Plan"). The Registration Statement also relates to such indeterminate number of additional
  shares of Common Stock of the Registrant as may be required pursuant to the Plan in the event
  of a stock dividend, reverse stock split, split-up, recapitalization, forfeiture of stock
  under the Plan or other similar event.

  This estimate is made pursuant to Rule 457(c) and (h) under the Securities Act of 1933, as
  amended (the "Securities Act"), solely for the purposes of determining the amount of the
  registration fee. The registration fee is based upon the average of the high and low sale
  price for a share of Common Stock, as reported on the Nasdaq Global Select Market as of a date
  within five business days prior to filing this Registration Statement.

  EXPLANATORY NOTE
  The Registrant previously filed a registration statement on Form S-8 on September 20, 2000
  under file number 333-46162 (the "Prior Registration Statement") identifying shares to be
  registered in connection with the Plan. In addition, Section 3(a) of the Plan provides that the
  maximum number of shares of Common Stock reserved for issuance under the Plan shall be increased,
  as of each June 30 and December 31 following the closing of the Registrant's initial public
  offering, by an additional positive number equal to twenty percent of the shares of Common Stock
  issued by the Registrant during the six-month period then ended (excluding shares issued in the
  Registrant's initial public offering). During the period from January 1, 2007 to December 31, 2007
  the Registrant issued an aggregate of 889,247 shares of Common Stock. As a result, the maximum
  number of shares of Common Stock reserved for issuance under the Plan has been increased by 20% of
  889,247, or 177,848 shares. By filing this Registration Statement in accordance with Instruction E
  to Form S-8, the Registrant hereby registers this additional number of shares.
  PART II
  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
  Item 3. Incorporation of Documents by Reference.
  Pursuant to General Instruction E to Form S-8, the Registrant hereby incorporates by reference
  the contents of its Registration Statement on Form S-8 filed with the Securities and Exchange
  Commission (the "Commission") on September 20, 2000 under file number 333-46162.
  Item 8. See the Exhibit Index which is incorporated by reference herein by reference.
  Item 9. Undertakings.
  (a) The undersigned Registrant hereby undertakes:
  (1) To file, during any period in which offers or sales are being made, a post-effective amendment
  to this Registration Statement:
  (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
  (ii) To reflect in the prospectus any facts or events arising after the effective date of the
  Registration Statement (or the most recent post-effective amendment thereof) which, individually
  or in the aggregate, represent a fundamental change in the information set forth in the
  Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of
  securities offered (if the total dollar value of securities offered would not exceed that which
  was registered) and any deviation from the low or high end of the estimated maximum offering
  range may be reflected in the form of prospectus filed with the Commission pursuant to Rule
  424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change
  in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table
  in the effective Registration Statement.
  (iii) To include any material information with respect to the plan of distribution not
  previously disclosed in the Registration Statement or any material change to such information in
  the Registration Statement;
  Provided, however, that:
  paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information
  required to be included in a post-effective amendment by those paragraphs is contained in
  reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or
  Section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are
  incorporated by reference in the Registration Statement.
  (2) That, for the purpose of determining any liability under the Securities Act of 1933, each
  such post-effective amendment shall be deemed to be a new Registration Statement relating to the
  securities offered therein, and the
  2
  Table of Contents
  offering of such securities at that time shall be deemed to be the initial
  bona fide
  offering
  thereof.
  (3) To remove from registration by means of a post-effective amendment any of the securities
  being registered which remain unsold at the termination of the offering.
  (b) The undersigned Registrant hereby undertakes that, for purposes of determining liability under
  the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a)
  or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
  1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new
  registration statement relating to the securities offered herein, and the offering of such
  securities at that time shall be deemed to be the initial
  bona fide
  offering thereof.
  (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
  permitted to directors, officers and controlling persons of the Registrant pursuant to the
  foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public policy as expressed in
  the Act and is, therefore, unenforceable. In the event that a claim for indemnification against
  such liabilities (other than the payment by the Registrant of expenses incurred or paid by a
  director, officer or controlling person of the Registrant in the successful defense of any action,
  suit or proceeding) is asserted by such director, officer or controlling person in connection with
  the securities being registered, the Registrant will, unless in the opinion of its counsel the
  matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
  question whether such indemnification by it is against public policy as expressed in the Act and
  will be governed by the final adjudication of such issue.
