National Instruments Annual Investor Conference Held in Conjunction With Company's NIWeek User Conference

Company Executives to Discuss Key Drivers of Growth

AUSTIN, Texas - Aug. 7, 2007 - National Instruments hosts its Annual Investor Conference in Austin, Texas, today in conjunction with NIWeek, the company's annual user conference. NIWeek serves as a key event for new product releases and technology demonstrations, in addition to providing an important forum for customers, members of the press, strategic partners and exhibitors to learn about and discuss the latest trends and technologies in test, control and design.

The investor conference begins with a keynote address by Dr. James Truchard, NI president and CEO. Following the keynote, the NI management team will discuss the company's key drivers of growth, product strategy and customer success in test as well as embedded and industrial control.

"Our vision of graphical system design has continued to gain adoption as companies have expanded their use of NI hardware and software, from testing their products to designing and prototyping them as well," Truchard said. "Our approach is further strengthened by the shift toward multicore processors and our introduction of LabVIEW 8.5, which empowers engineers and scientists to maximize system performance with little rewrite to their software code."

The event is scheduled to begin at 11:30 a.m. EST. To listen to the live webcast, please visit www.ni.com/nati.
