SonoSite Repurchases $60 Million Of Its Convertible Notes

Repurchase to result in $11 million pre-tax gain in Q4 Q3 Conference Call scheduled today at 1:30 pm Pacific/4:30 pm Eastern

BOTHELL, WA - October 30, 2008 - SonoSite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried ultrasound for point-of-care medicine, today announced that it has repurchased in the open market an aggregate of $60.3 million of the principal outstanding amount of its 3.75% convertible notes due 2014 for total consideration of approximately $47.4 million in cash, excluding accrued interest. Following these repurchases, convertible notes representing $164.7 million of principal debt are outstanding. As a result of the repurchases that have occurred to date, SonoSite expects to report a pre-tax gain of approximately $11 million, net of deferred issuance costs, in the fourth quarter. In connection with the issuance of these convertible notes in July 2007,

SonoSite entered into a convertible note hedge transaction and a warrant transaction with an affiliate of one of the underwriters. These transactions were intended to reduce the potential dilution to SonoSite's shareholders upon any conversion of the notes. As a result of the recent repurchases, the associated convertible note hedges and a corresponding number of warrant positions will be unwound. The payment received from unwinding the associated convertible note hedges, less the cost of the warrant transaction, will result in net proceeds to SonoSite of approximately $400,000. SonoSite currently has in excess of $280 million in cash and investments. SonoSite's board of directors has authorized the repurchase of additional convertible notes in the open market or in privately negotiated transactions as management deems appropriate. In the event of additional repurchases, the company would continue to unwind the associated hedges and a corresponding number of warrant positions. C
