Autodesk Completes Acquisition of Skymatter, Makers of Mudbox 3D Brush-based Modeling Software

Strengthens Autodesk’s Entertainment and Design Offering

SAN RAFAEL, Calif., Oct. 16, 2007 — Autodesk, Inc. (NASDAQ: ADSK) has completed the acquisition
of substantially all the assets of Skymatter Limited, the New Zealand-based, privately held developer of
Mudbox 3D modeling software. On August 6, 2007, Autodesk announced an agreement to purchase
Skymatter’s assets. Terms of the transaction were not disclosed.

This acquisition expands Autodesk’s offering for the film, television and game market segments, while
providing additional growth opportunities for other design disciplines, such as 3D automotive and
industrial design. Mudbox has shaped photorealistic creatures for the blockbuster film King Kong, as well
as upcoming films The Golden Compass, Fred Claus and Inkheart.

“Mudbox is complementary to the Autodesk 3ds Max and Autodesk Maya software products, providing
our customers with an additional suite of tools for modeling, prototyping and detailing,” said Marc Petit,
senior vice president, Autodesk Media & Entertainment. “When Mudbox launched two years ago, it
became an overnight success in the media and entertainment industry. It has a powerful brush-based
modeling workflow and is renowned for its robust toolset and user-friendliness, making digital sculpting
easy for both traditional sculptors and digital artists. As part of the Autodesk product line, we plan to
accelerate the pace of Mudbox innovation.”

Skymatter founders Andrew Camenisch, Dave Cardwell and Tibor Madjar have joined Autodesk’s Media
& Entertainment business. Madjar commented, “Mudbox is a perfect fit within Autodesk. The company is
in a unique position, providing the leading software for design and entertainment industries. Andrew,
Dave and I look forward to scaling the growth of Mudbox with Autodesk. Our priority is to continue
developing a standalone version of Mudbox. We will also work to achieve greater interoperability between
the Mudbox toolset and 3ds Max and Maya.”
