persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of such void or unenforceable provision.

The undersigned stockholder (“Stockholder”) of MOLDFLOW CORPORATION, a Delaware
corporation (the “Company”), hereby irrevocably (to the fullest extent permitted
by law) appoints Carl Bass and Pascal W. Di Fronzo of AUTODESK, INC., a Delaware
Corporation (“Parent”), and each of them, as the sole and exclusive attorneys
and proxies of the undersigned, with full power of substitution and
resubstitution, to vote and exercise all voting and related rights (to the full
extent that the undersigned is entitled to do so) with respect to all of the
shares of capital stock of the Company that now are or hereafter may be
beneficially owned by the undersigned, and any and all other shares or
securities of the Company issued or issuable to Stockholder on or after the date
hereof (collectively, the “Shares”) in accordance with the terms of this
Irrevocable Proxy until the Expiration Date (as defined below). Upon
Stockholder’s execution of this Irrevocable Proxy, any and all prior proxies
given by Stockholder with respect to any Shares are hereby revoked and
Stockholder agrees not to grant any subsequent proxies with respect to the
Shares until after the Expiration Date.

This Irrevocable Proxy is irrevocable to the fullest extent permitted by law, is
coupled with an interest and is granted pursuant to that certain Tender and
Voting Agreement of even date herewith by and among Parent and Stockholder (the
“Tender and Voting Agreement”), and is granted in consideration of Parent
entering into that certain Agreement and Plan of Merger of even date herewith
(the “Merger Agreement”), among Parent, Switch Acquisition Company, a Delaware

Company. The Merger Agreement provides for, among other things, (i) an offer by
Merger Sub (the “Offer”) to pay Twenty Two Dollars ($22.00) in cash (the “Offer
Price”) for each of the issued and outstanding shares of capital stock of the
Company and (ii) the merger of Merger Sub with and into the Company, pursuant to
which all outstanding shares of capital stock of the Company will be converted
into the right to receive the consideration set forth in the Merger Agreement.

As used herein, the term “Expiration Date” shall mean the earlier to occur of
(i) such date and time as the Merger Agreement shall have been terminated
pursuant to Article VIII thereof, (ii) the Effective Time, and (iii) such date
and time as any amendment or change to the Merger Agreement is effected without
Stockholder’s consent that decreases the Offer Price.

The attorneys and proxies named above, and each of them, are hereby authorized
and empowered by Stockholder, at any time prior to the Expiration Date, to act
as the undersigned’s attorney and proxy to vote the Shares, and to exercise all
voting, consent and similar rights of Stockholder with respect to the Shares
(including, without limitation, the power to execute and deliver written
consents) at every meeting of the Company Stockholders called, and at every
adjournment or postponement thereof, and on every action or approval by written
consent of the Company Stockholders: (i) in favor of the adoption of the Merger
Agreement (as it may be amended from time to time), and in favor of each of the
other transactions contemplated by the Merger Agreement; (ii) against approval
of any Acquisition Proposal; (iii) against any action that is intended, or could
reasonably be expected to, impede, interfere with, delay, postpone, discourage
or adversely affect the Offer; and (iv) that would reasonably be expected to
result in the failure of any Conditions to the Offer to be satisfied.
