FOR IMMEDIATE RELEASE

Columbia Laboratories Receives Nasdaq Minimum Bid Price Non-compliance Letter

LIVINGSTON, NJ - March 6, 2012 - Columbia Laboratories Inc. (Nasdaq: CBRX) received a notice on March 6, 2012, from the Nasdaq Stock Market indicating that it no longer meets the minimum bid price requirement for continued listing on the Nasdaq Global Market as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Rule”). The notice stated that the bid price of the Company's common stock has closed below the required minimum $1.00 per share for the previous 30 consecutive business days. The Nasdaq notice has no immediate effect on the listing of the Company's common stock.

In accordance with Nasdaq rules, the Company has 180 calendar days to regain compliance with the Rule. If at any time before September 4, 2012, the bid price of Columbia's common stock closes at $1.00 per share or higher for a minimum of 10 consecutive business days, Nasdaq will notify the Company that it has regained compliance with the Rule.

In the event the Company does not regain compliance with the Rule prior to September 4, 2012, Nasdaq will notify the Company that its securities are subject to delisting. However, the Company may be eligible for additional time. To qualify, the Company may apply to transfer the listing of its common stock to the Nasdaq Capital Market if it satisfies all criteria for initial listing on the Nasdaq Capital Market, other than compliance with the minimum bid price requirement. If such application to the Nasdaq Capital Market is approved, then the Company may be eligible for an additional grace period.

The Company is considering actions that it may take in response to this notification in order to regain compliance with the continued listing requirements.
