SonoSite Announces Commencement Of $100 Million Common Stock Tender Offer

BOTHELL, WA – January 19, 2010 – SonoSite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried ultrasound for the point-of-care, today announced the commencement of its previously announced tender offer to repurchase up to $100 million of the Company's common stock for cash through a modified "Dutch Auction" tender offer. As previously announced, under the terms of the tender offer, SonoSite shareholders 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 share closing price for our common stock on January 8, 2010, which was the trading day immediately preceding the original announcement of the proposed tender offer. The tender offer will expire at 5:00 p.m., New York City time, on Friday, February 19, 2010, unless extended by SonoSite.

Tenders of shares must be made on or prior to the expiration of the tender offer and may be withdrawn at any time on or prior to the expiration of the tender offer. The tender offer is subject to various terms and conditions described in offer materials that were publicly filed and distributed to shareholders today. Additional copies of the offer materials will also be available from the Information Agent, Georgeson Inc. The Dealer Manager for the tender offer is J.P. Morgan Securities Inc. 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 tender offer or at which price or prices to tender their shares.

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 or prices within the stated range at which they will tender their shares.
