Chadbourne & Parke LLP Welcomes Securities Litigator

Joaquin M. Sena to the Firm as Counsel

Addition of New Counsel Further Expands Securities Litigation
and White Collar Defense Practices in Washington, D.C.

New York, NY – April 19, 2004 – The international law firm of Chadbourne & Parke LLP announced today that securities litigator Joaquin M. Sena, 43, has joined the Firm as counsel, resident in Washington, D.C. Mr. Sena comes to Chadbourne from the Securities and Exchange Commission, where he was Assistant Chief Litigation Counsel and most recently served as lead litigation attorney in the SEC’s financial fraud case against Parmalat Finanziaria S.p.A.

Mr. Sena is the fourth former SEC enforcement official to join the Firm in the past two years.

“We are pleased to welcome Jack to Chadbourne,” said Charles K. O’Neill, the Firm’s Managing Partner. “He brings considerable firsthand SEC experience to the Firm and continues the expansion not only of our securities litigation and regulatory enforcement practice group, but also to our white collar defense practice group.” Both practice groups have experienced rapid growth to accommodate the Firm’s growing high profile presence in these practice areas.

Mr. Sena joins the Firm’s securities litigation practice, which brings together more than 20 attorneys in the New York, Washington, D.C. and Los Angeles offices. Members of the practice include partner Thomas V. Sjoblom, who heads the practice group, and counsels Clifford C. Hyatt and John G. Moon, all of whom also served previously as enforcement officials at the SEC.

Mr. Sena also adds depth to the Firm’s white collar criminal defense practice, whose members include partner Kenneth A. Caruso, former Deputy Associate United States Attorney General in the Department of Justice in Washington, D.C.; partner Abbe David Lowell, former DOJ Special Assistant U.S. Attorney and now a prominent defense attorney in criminal and Congressional matters; Mr. Sjoblom, former Special Assistant U.S. Attorney in three different judicial districts across the United States; and Mr. Moon, former Special Assistant U.S. Attorney in the DOJ Criminal Division, Fraud Section in Washington, D.C.

“I have known Jack as a first-rate litigator since my days at the SEC,” said Mr. Sjoblom, who spent nearly 20 years at the SEC prior to entering private practice in 1999. “His SEC investigatory and trial expertise adds significant cache to our securities litigation and regulatory practice group, to the Firm as a whole, and for our clients.”

As Assistant Chief Litigation Counsel at the SEC, Mr. Sena was responsible for representing the SEC in all phases of litigation in federal courts against defendants alleged to have violated federal securities laws. In addition to serving as lead litigation attorney in the Parmalat case, Mr. Sena also worked on the civil case against Millennium Financial Ltd. In that prosecution, he helped investigate the offshore boiler room and served as lead litigation counsel in the suit against the company and individuals behind it; they were accused of defrauding more than 700 investors in more than 20 countries.

Previously, Mr. Sena served as an SEC Staff Attorney, investigating violations of federal securities laws involving insider trading, market manipulation, financial fraud and the fraudulent offer and sale of unregistered securities. Mr. Sena also served as a Special Assistant U.S. Attorney for the Eastern District of Virginia. In this capacity he handled all stages of prosecutions for misdemeanor and felony cases, including investigations and trials and appeals.

Mr. Sena received his B.A. from Brown University and his J.D. from the University of Pennsylvania Law School.
