NOVA MEASURING INSTRUMENTS BELIEVES NANOMETRICS
CLAIM IS WITHOUT MERIT

Nova’s Earlier Lawsuit Against Nanometrics is Proceeding as Judge Denies
Nanometrics’ Motion for Summary Judgment

Rehovoth, Israel – April 5, 2006 – Nova Measuring Instruments, Ltd. (Nasdaq: NVMI), the market leader in integrated measurement and process control for the semiconductor industry, today announced that it has received notice of a patent infringement lawsuit brought by Nanometrics Incorporated (Nasdaq: NANO), alleging infringement of US Patent No. Re: 34,783. Nova believes that this lawsuit is without merit and will defend vigorously against the claim. Nova also indicated that its own patent infringement lawsuit against Nanometrics is proceeding after a judge recently denied Nanometrics’ motion for a summary judgment seeking to invalidate Nova’s patent.

Nova is confident that its products do not infringe Nanometrics’ patent and believes the Nanometrics’ lawsuit is a tactical maneuver in response to developments in Nova’s continuing lawsuit against Nanometrics, which was launched in March 2005, to protect its own intellectual property. Nanometrics patent was originally issued in 1991 and was “re-issued” in 1994 due to defects in the original patent.

“Given the age of this patent and the fact that it has been over a year since Nanometrics first indicated that they planned to review their patent portfolio in response to our lawsuit, we see this merely as an attempt to deflect attention from our lawsuit,” said Dr. Moshe Finarov, VP Technology and CTO of Nova. “This move came immediately after the U.S. District Court for the Northern District of California ruled in favor of Nova.”
