BOTHELL, WA – January 11, 2010 – Sonosite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried ultrasound for the point-of-care, today announced that its Board of Directors has authorized Sonosite to repurchase up to $150 million of the Company’s common stock or outstanding convertible notes for cash. In connection with the repurchase authorization, the company will purchase up to $100 million of the Company’s common stock through a modified “Dutch Auction” tender offer.

Sonosite intends to commence the tender offer during the week of January 18, 2010. Under the terms of the proposed tender offer, Sonosite shareholders will have the opportunity to tender some or all of their shares at a price within the range of $26.10 to $30.00 per share. Based on the number of shares tendered and the prices specified by the tendering shareholders, Sonosite will determine the lowest per share price within the range that will enable it to buy $100 million in shares, or such lesser number of shares that are properly tendered.

All shares accepted for payment will be paid the same price, regardless of whether a shareholder tendered such shares at a lower price within the range. At the minimum price of $26.10 per share, Sonosite would repurchase a maximum of 3,831,417 shares, which represents approximately 22% of Sonosite’s currently outstanding common stock. Sonosite will fund the repurchase from available cash on hand. The low and high ends of the price range represent approximately a 0% and 15% premium, respectively, to the most recent share closing price of $26.10 per share. Based on the January 8, 2010 closing price, the share price has increased 10% year-to-date.

The tender offer will be subject to various terms and conditions as will be described in offer materials that will be publicly filed and distributed to shareholders at the time of commencement of the tender offer during the week of January 18, 2010. Additional copies of the offer materials will also be available from the Information Agent, Georgeson Inc. The Dealer-Manager for the tender offer will be J.P. Morgan Securities Inc. Kevin M. Goodwin, the Company’s President and Chief Executive Officer, said, “After evaluating various opportunities for two years, we concluded that the best investment of our cash was in our own stock. Moreover, we believe that the tender offer will benefit stockholders by providing an efficient mechanism for those who desire liquidity at a premium over current trading prices and, for our remaining stockholders, an enhanced ability to participate in the long-term earnings potential of our business.”

Neither Sonosite’s management, nor any of its board of directors, executive officers, the dealer manager, the information agent or the depositary is making any recommendation to shareholders as to whether to tender or refrain from tendering their shares in the proposed tender offer. The company’s executive officers, senior management and directors have advised the company that they do not intend to tender any of their shares in the tender offer. Shareholders must decide how many shares they will tender, if any, and the price within the stated range at which they will tender their shares. Shareholders should consult their financial and tax advisors in making this decision.
