CORAL GABLES, Fla., Dec. 27, 2012 (GLOBE NEWSWIRE) -- Catalyst Pharmaceutical Partners, Inc.
(Nasdaq:CPRX) announced today that it received a Nasdaq Staff Deficiency Letter, dated December
24, 2012, indicating that the Company is not in compliance with the Minimum Bid Price requirement
set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market.

The Nasdaq Listing Rules (the "Rules") require listed securities to maintain a minimum bid price
of $1.00 per share and, based upon the closing bid price for the last 30 consecutive business
days, the Company no longer meets this requirement. In light of the deficiency, the Rules also
provide the Company with a grace period of 180 calendar days in which to regain compliance. If at
any time during this grace period the bid price of the Company's security closes at or above $1.00
per share for a minimum of ten consecutive business days, the Nasdaq Stock Market will provide the
Company with a written confirmation of compliance and the matter will be closed.

In the event the Company does not regain compliance with the Rule prior to the expiration of the
grace period, the Company may be eligible for an additional 180-day grace period if at such time
it meets the initial listing standards for listing on the Nasdaq Capital Market, with the
exception of the bid price requirement.

The Company understands the Nasdaq requirements and believes it will be able to regain compliance
with the Rules within the allotted grace period.
