EnteroMedics Inc. (NASDAQ: ETRM), the developer of medical devices using neuroblocking technology to treat obesity and other gastrointestinal disorders, announced today that on November 13, 2009 it received two Nasdaq Staff Deficiency Letters indicating that, for 30 consecutive business days, the Company's listed securities did not maintain the minimum Market Value of Publicly Held Share (MVPHS) of $15,000,000 as required by Listing Rule 5450(b)(2)(C) and did not maintain a minimum bid price of $1.00 per share as required by Listing Rule 5450(a)(1).

The Company has been provided 90 calendar days, or until February 11, 2010, to regain listing compliance with rule 5450(b)(2)(C), which can be achieved if the Company’s MVPHS closes at $15,000,000 or more for a minimum of ten consecutive

business days during this time, and 180 days, or until May 12, 2010, to regain listing compliance with rule 5450(a)(1), which can be achieved if the Company’s common stock closes at or above $1.00 per share for a minimum of ten consecutive business days during this time. EnteroMedics previously announced that, on October 19, 2009, it received a Nasdaq Staff Deficiency Letter indicating that, for ten consecutive business days, the Company's common stock did not maintain the minimum Market Value of Listed Securities (MVLS) of $50,000,000 as required by Listing Rule 5450(b)(2)(A). The Company was provided 90 calendar days, or until January 19, 2010, to regain listing compliance with rule 5450(b)(2)(A). The Company’s common stock will continue to be listed on the Nasdaq Global Market during this period.

In the event the Company does not regain compliance prior to expiration of the respective grace periods, it will receive written notification that its securities are subject to delisting. The Company may, at that time, appeal the Staff's determination to a Hearing’s Panel. Such an appeal, if granted, would stay delisting until a Panel ruling.

Alternatively, the Company may choose to apply for transfer to the Nasdaq Capital Market, provided it satisfies the requirements for continued listing on that market. There can be no assurance that the Company will be able to reestablish or maintain compliance with listing criteria on either Nasdaq market or that an appeal, if taken, would be successful.
