TRUSTED ADVISOR FOR TWELVE YEARS
"Since Sonosite opened for business in April 1998, Kirby Cramer has imbued Sonosite with a long-term discipline and persistent strategic opportunism that has led the company to achieve a revenue run rate of over a quarter billion dollars and an installed base of 60,000 systems from a standing start in 1999," said Kevin M. Goodwin, Sonosite President and CEO. "We simply would not be where we are today without Kirby's guidance and encouragement. We wish to thank and fully acknowledge his unique contributions over the past twelve years." In recognition of Mr. Cramer's years of service to Sonosite, the Board of Directors conferred upon him the honorary title of Chairman Emeritus to be held during the balance of his term as a director.

STRUCTURE CHANGES FOR 2011
With the retirement of Mr. Cramer, following the annual shareholders meeting in April 2011, the Board will have adopted a reduced structure and simplified committee format that will move the company from nine to seven independent members. Additionally, steps have already been taken to reduce the number of committees from five to three (Audit, Compensation, and Nominating and Corporate Governance). The structure is consistent with Nasdaq standards and SEC requirements. "The cumulative effect of these changes will result in a more streamlined and cost effective structure that will continue to support Sonosite's corporate governance and strategic oversight responsibilities," said Carmen Diersen, the company's Chair of its Corporate Governance Committee.
