Murray, Frank & Sailer LLP filed a class action lawsuit, civil case number 09-cv-05367-HRL, in the United States District Court for the Northern District of California, San Jose division, against Hansen Medical, Inc. (“Hansen” or the “Company”) (NASDAQ:HNSN) and certain of its officers and directors, on behalf of shareholders who purchased Hansen common stock between May 1, 2008 and October 18, 2009, inclusive (the “Class Period”).

Throughout the Class Period defendants violated federal securities laws by issuing materially false and misleading statements regarding the Company’s financial results and compliance with Generally Accepted Accounting Principles. Specifically, the defendants made false and/or misleading statements and/or failed to disclose: (1) that the Company improperly recognized revenue; (2) that, as a result, the Company’s revenue

and financial results were overstated during the Class Period; (3) that the Company’s financial results were not prepared in accordance with Generally Accepted Accounting Principles (“GAAP”); (4) that the Company lacked adequate internal and financial controls; and (5) that, as a result of the above, the Company’s financial statements were materially false and misleading at all relevant times.

On October 19, 2009, Hansen announced that as a result of its audit committee investigation it would restate its 2008 financial statements and financial statements for the first and second quarters of 2009 due to errors arising from “potential irregularities outside of the accounting department.” According to the Company, Hansen identified systems for which revenue should have been recognized in a later period than the period in which it was recognized, and revenue on systems that should have been reflected as deferred revenue on its balance sheet as of June 30, 2009. As a result of this news, the price of Hansen shares declined $0.31 per share, more than 9%, to close on October 19, 2009, at $3.12 per share, on unusually heavy trading volume.
