NYMEX Chairman Will Not Seek Re-Election

Mon Mar 20 2006

NEW YORK, March 20, 2006 — NYMEX Holdings, Inc. (NYMEX) announced today that Chairman Mitchell Steinhause has informed the Board of Directors that he will not seek re-election.

Mr. Steinhause has been a member of the Exchange since 1975 and a Board member for 14 years, including two years as Chairman and four years as Vice Chairman.

Under his leadership, NYMEX solidified its position as the world's largest and most important physical commodities exchange. During his chairmanship, revenue, seat prices and volumes all rose to record levels, and the Exchange launched strategic international initiatives in London and Dubai. Most recently, Mr. Steinhause spearheaded the transaction in which General Atlantic invested $160 million for a 10% equity stake in NYMEX, which was overwhelmingly approved by NYMEX shareholders earlier this month.

"I am very proud of what this leadership team has accomplished over the past several years and I am pleased with the direction in which NYMEX is headed," said Mr. Steinhause. "I intend to remain an active member on the floor of the Exchange and I look forward to contributing to its future success in that capacity."
