INVESTOR ALERT: KGS Announces Initial Filing of Shareholder Class Action Lawsuit Against Optionable, Inc.

NEW ORLEANS, LA -- (MARKET WIRE) -- May 11, 2007 -- Kahn Gauthier Swick, LLC ("KGS") has filed the first class action lawsuit against Optionable, Inc. ("Optionable" or the "Company") (OTCBB: OPBL), in the United States District Court for the Southern District of New York, Civil Action No. 07cv3753, on behalf of shareholders who purchased shares of the Company in connection with its Initial Public Offering ("IPO") in or about May 9, 2005, or who purchased shares thereafter in the open market (the "Class Period"). No class has yet been certified in this action.

UNTIL A CLASS IS CERTIFIED, YOU ARE NOT PERSONALLY REPRESENTED BY COUNSEL UNLESS YOU RETAIN AN ATTORNEY.

Optionable and certain of its officers and directors are charged with including, or allowing the inclusion of, materially false and misleading statements in the Registration Statement and Prospectus issued in connection with the IPO, in violation of the Securities Act of 1933.

The Complaint alleges that, unbeknownst to investors, defendants failed to conduct an adequate due diligence investigation into the Company prior to the IPO, and failed to disclose at the time of the IPO that: (1) two of the Company's board members, including Chairman Mark Nordlicht, and its only purported independent director, Albert Helmig, were actually related parties and board members of a company called Platinum Energy; (2) the Company's customer base suffered from greater concentration than previously reported, with Bank of Montreal directly connected to over 80% of revenues, higher than the 20% to 30% reported; and (3) defendants had conspired with Bank of Montreal ("BMO") brokers to provide false trade data that was designed to avoid reporting hundreds of millions of dollars in trading losses -- losses that, if disclosed, would have terminated the BMO trading relationship.

It was only beginning in late April 2007 -- after defendants sold $28.94 million of their own shares to NYMEX Holdings in a private sale -- that investors learned the truth about the Company. On April 30, 2007, BMO's announcement of over $300 million in options-related losses shed light on the magnitude of Optionable's reliance on BMO for a large portion of its revenues. Days later on May 10, 2007, BMO suspended trading through Optionable and announced that its private forensic accountants had discovered that its own brokers -- who by then had been terminated -- had conspired to under-report trading losses, in order to maintain trading and avoid accountability to BMO.

On this news, Optionable's shares collapsed from just under $5.00 per share on April 30, 2007 to just over $1.00 per share on May 10, 2007 -- a decline of almost 80% in two trading days, on huge volume of tens of millions of shares.

If you wish to serve as lead plaintiff in this case, you must move the Court no later than July 10, 2007. Any member of the purported 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.
