Shareholder Class Action Filed Against AtriCure, Inc. by the Law Firm of Schiffrin & Barroway, LLP

12 December 2006

The following statement was issued today by the law firm of Schiffrin & Barroway, LLP:

Notice is hereby given that a class action lawsuit was filed in the United States District Court for the Southern District of New York on behalf of all common stock purchasers of AtriCure, Inc. (Nasdaq: ATRC) ("AtriCure" or the "Company") pursuant and/or traceable to the Company's initial public offering on or about August 4, 2005 through February 16, 2006, inclusive (the "Class Period").

If you wish to discuss this action or have any questions concerning this notice or your rights or interests with respect to these matters, please contact Schiffrin & Barroway, LLP (Darren J. Check, Esq. or Richard A. Maniskas, Esq.) toll free at 1-888-299-7706 or 1-610-667-7706, or via e-mail at info@sbclasslaw.com.

The Complaint charges AtriCure and certain of its officers and directors with violations of the Securities Act of 1933. More specifically, the Complaint alleges that AtriCure's Registration Statement and Prospectus issued in connection with the Company's initial public offering on or about August 4, 2005 failed to disclose that the Cleveland Clinic, where a significant portion of procedures with the Company's products were being performed, was an investor in the Company and that doctors from the Cleveland Clinic had been paid consultants to the Company.

On February 16, 2006, AtriCure announced financial results for the fourth quarter of 2005 and the fiscal year ended December 31, 2005. Among other things, the Company reported that it was experiencing a "negative impact" on its business due to the revelations concerning the Cleveland Clinic. In response to this announcement, the price of AtriCure common stock dropped from $10.36 per share to $8.04 per share on extremely heavy trading volume.

Schiffrin & Barroway is a driving force behind corporate governance reform, and has recovered billions of dollars on behalf of institutional and individual investors from the United States and around the world.

If you are a member of the class described above, you may, not later than February 9, 2007, move the Court to serve as lead plaintiff of the class, if you so choose. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class. Under certain circumstances, one or more class members may together serve as "lead plaintiff." Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. You may retain Schiffrin & Barroway, or other counsel of your choice, to serve as your counsel in this action.
