INVESTOR ALERT: Former Attorney General of Louisiana Charles C. Foti, Jr. and KSF Notify Sequenom, Inc. Investors of

NEW ORLEANS, LA, May 27 (MARKET WIRE) --
Kahn Swick & Foti, LLC ("KSF") announces that investors have only until
June 30, 2009 to apply for lead plaintiff in a securities fraud class
action lawsuit filed in the United States District Court for the Southern
District of California, on behalf of purchasers of the common stock of
Sequenom, Inc. ("Sequenom" or the "Company") (NASDAQ: SQNM) between June
4, 2008 and April 29, 2009, inclusive (the "Class Period"). No class has
yet been certified in this action.

If you would like to discuss your legal rights, along with the lead
plaintiff position and its related responsibilities including overseeing
lead counsel with a goal of obtaining a fair settlement, you may e-mail or
call KSF Managing Partner Lewis Kahn, without obligation or cost to you,
toll free 1-866-467-1400, ext. 100, via cell phone after hours at
504-301-7900, or by email at lewis.kahn@ksfcounsel.com.

Sequenom and certain of its officers and directors are charged with
violating the Securities Exchange Act of 1934 by issuing a series of
materially false and misleading statements during the Class Period. On
April 29, 2009, the Company revealed significant problems related to its
Down syndrome test "SeQureDx," including the mishandling of test data and
associated results, which would cause it to be unable to bring SeQureDx to
the market timely. As a result of this news, Sequenom's shares fell by
over $11, a one day decline of over 75%, on high volume of over 85 million
shares.

If you wish to serve as lead plaintiff in this class action lawsuit, you
must move the Court no later June 30, 2009. Any member of the putative
class may move the Court to serve as lead plaintiff through counsel of
their choice, or may choose to do nothing and remain an absent class
member. If you would like to discuss your legal rights, you may e-mail or
call KSF Managing Partner Lewis Kahn, without obligation or cost to you,
toll free 1-866-467-1400, ext. 100, after hours via cell phone
504-301-7900, or by email at lewis.kahn@ksfcounsel.com. To learn more
