Item 1.02. Termination of a Material Definitive Agreement

Timothy Triplett, the Company's Executive Vice President and General Manager
Manufacturing Solutions Business Unit, has informed the Company of his decision
to resign from employment with the Company, which resignation will be effective
sometime during the quarter ended June 30, 2006, as mutually determined by the
Company and Mr. Triplett. At such time, the Amended and Restated Employment
Agreement between the Company and Mr. Triplett, dated July 8, 2005 (the
"Agreement") will terminate.

The Agreement was for an initial period of one year, and is automatically
extended for one additional year on the anniversary date unless either party has
given notice that it does not wish to extend the Agreement. The Agreement
provides for the payment of base salary and incentive compensation and for the
provision of certain fringe benefits to Mr. Triplett. The Agreement imposes
certain ongoing confidentiality obligations on Mr. Triplett. In addition the
Agreement and Plan of Merger dated January 23, 2004 (the "Merger Agreement") by
and among Moldflow Corporation, American MSI Corporation, Mr. Triplett and
certain other parties, requires Mr. Triplett to refrain from competing with the
Company and from soliciting the Company's employees through January 23, 2009,
subject to certain other terms and conditions as included in the Merger
Agreement.

The Agreement also provides for certain payments and benefits should Mr.
Triplett's employment be terminated because of death or disability, by him for
good reason or by the Company without cause, as further defined in the
Agreement. In general, in the case of a termination by Mr. Triplett for good
reason, or by the Company without cause, Mr. Triplett would receive one year of
cash compensation, including base salary and an average of cash bonuses paid
over the past five years, an extension of benefits for one year and an
acceleration of vesting for stock options and restricted stock which otherwise
would vest during the next twelve months. Upon a change of control, as defined
in the Agreement, he is eligible for a lump sum payment of eighteen months of
cash compensation, including base salary and on-target cash bonus for the
current fiscal year, an extension of benefits for one year and an acceleration
of vesting for all outstanding stock options and restricted stock. Because Mr.
Triplett is voluntarily terminating his Agreement with the Company, no cash
compensation or extension of benefits is required pursuant to the terms of the
Agreement and any vested but unexercised stock options held by Mr. Triplett may
be exercised for a period of three (3) months following the date of termination.

This matter is discussed further in the press release issued by Moldflow
Corporation on April 13, 2006 which is attached to this Form 8-K as Exhibit 99.1
and is incorporated herein by reference.
