Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
The restricted stock units vest and become exercisable based on time and performance milestones set by the Issuer.
On February 22, 2011, the common stock of National Instruments Corporation split 3-for-2, resulting in the reporting person's ownership of additional shares of common stock.
