"Our results for the third quarter were right on target," said Kevin M. Goodwin, Sonosite president and CEO. "This progress puts us in position to pursue our first quarterly profit in the fourth quarter. Physician response to our newly launched iLook product line has been extremely positive, and it is still early yet. We are optimistic about the future of this product line."

Quarterly Highlights Include:
Sales of Sonosite's flagship products, the Sonosite 180PLUS and SonoHeart ELITE systems, were strong - Since launching its first product just over 36 months ago, Sonosite has now shipped nearly 8,500 systems.
Factory volumes increased, leading to continued manufacturing efficiencies - Production volumes increased in the third quarter driven by increased sales, the launch of  iLook products, and preparation for the seasonally strong fourth quarter. European direct operations strengthened by addition of sales representatives. Deloitte & Touche's "FAST 50" Program named Sonosite one of Washington State's Rising Stars - The award is based on a company's revenue growth from 1999 through 2001. Sonosite's revenue more than quadrupled from $10.3 million in 1999 to $45.7 million in 2001.

Outlook
"We expect to continue our year-over-year quarterly growth rates of at least 50 percent, with revenue expectations for the fourth quarter of $25 million to $27 million," Goodwin said. "Margins are expected to approach 60 percent in the fourth quarter. Expenses in the fourth quarter are estimated at $15 million, and we expect earnings in the range of $0.01 to $0.05 per share. We anticipate full-year profitability in 2003."
