                world's largest meeting and exposition devoted to
                automotive engineering and product technology.

    Where/When: SAE World Congress, Cobo Center, Detroit, MI,
                April 11-14 2005.
               (The MathWorks will be in Booth # 2323.)

Experts from The MathWorks will participate in the SAE World Congress 2005 technical program and share their expertise in Model-Based Design, production code generation, and physical modeling for the automotive industry. The MathWorks will present three technical papers, chair a session on modeling, and participate in a panel discussion with global automotive manufacturers, suppliers and academic experts:

--  Tuesday, April 12, 9:30 a.m., Room D3-28

        Robyn Jackey and Paul Smith of The MathWorks and Steven
        Bloxham of Compressor Control Company will present a paper
        titled "Physical System Model of a Hydraulic Energy Storage
        Device for Automotive Application."

        As part of the Advanced Hybrid Vehicle Powertrains (Part 3 of
        5) session (Code: P21,) this session will discuss alternatives
        to chemical batteries for some hybrid vehicle applications,
        including an electromechanical battery (EMB) that combines an
        electric machine with hydrapneumatics to provide energy
        capture, storage, and propulsion assistance.

    --  Wednesday, April 13, 8:00 a.m., Room D2-09/10

        Peter Maloney of The MathWorks will chair the Electronic
        Engine Controls - Modeling II session (Part 5; Code P24).

    --  Wednesday, April 13, 3:00 p.m., Room W1-54

        Tom Erkkinen of The MathWorks will present a paper titled
        "Model Style Guidelines for Production Code Generation."

        As part of the Distributed Embedded Systems Energy (Parts 1 &
        2) session (Code: AE9), this session will provide model style
        guidelines and best practices for automatically generating
        optimized fixed-point and floating-point code.

    --  Wednesday, April 13, 5:00 p.m., Room D2-09/10

        Peter Maloney of The MathWorks will participate in the panel
        "Electronic Engine Controls Discussion Panel--What are the
        Critical Issues for the Next 5 Years?" (Part 8).

        Other panelists include Dennis M. Bogden, General Motors
        Corp.; Elbert Hendricks, Technical University of Denmark;
        Patrick Leteinturier, Infineon Technologies AG; Peter M. Olin,
        Delphi Corp.; Giorgio Rizzoni, Ohio State University; Ron
        Stence, Freescale Semiconductor; and Richard K. Stobart,
        University of Sussex.

    --  Thursday, April 14, 10:15 a.m., Room W1-54

        Arvind Hosagrahara and Paul Smith of The MathWorks will
        present a paper titled "Measuring Productivity and Quality in
        Model-Based Design."

        Included in the Software/Hardware Systems (Parts 1 & 2)
        session (Code: AE17), this session will discuss how
        productivity and quality are measured differently when using
        Model-Based Design and will share an automatic, noninvasive
        measurement technique for gathering accurate metrics. Arvind
        and Paul will describe specific measurements that should be
        captured when using Model-Based Design and introduce a free
        tool that can capture these process metrics in Simulink(R) and
        Stateflow(R).

Visit The MathWorks in Booth # 2323 to learn more about the Company's software tools and how they are being deployed by the world's leading automotive manufacturers. The MathWorks will showcase the use of Model-Based Design with in-booth demonstrations on powertrain, body electronics, chassis, and safety system development. MathWorks Connections Program partners, including IPG Automotive, TESIS, United Electronics Industries, MotoTron, Prodrive, ETAS, Xilinx, and CapeWare Software, will also feature demonstrations in the booth.
