NYMEX to List Energy Futures Contracts on CME Globex® Platform Through 2016
Establishes Robust Electronic Trading Complement to NYMEX’s Open Outcry Platform; CME Globex First Electronic Derivatives Trading Platform With Global Access to All Major Asset Classes

NYMEX Holdings, Inc., parent company of the preeminent physical futures exchange, and CME, the world’s largest and most diverse financial exchange, announced today that they have signed a definitive technology services agreement under which CME will become the exclusive electronic trading services provider for NYMEX’s energy futures and options contracts. Access to electronic trading of NYMEX products will be available virtually 24 hours a day on the CME Globex® electronic trading platform.

Initial trading of NYMEX energy products on CME Globex, currently scheduled to begin in the second quarter of 2006, is expected to include side-by-side trading of NYMEX standard-sized and NYMEX miNY™ energy futures contracts for crude oil, natural gas, heating oil and gasoline with NYMEX’s floor-based products during open outcry trading hours and when the NYMEX trading floor is closed. In the third quarter, all products trading on NYMEX ACCESS®, the exchange’s after hours electronic trading platform, are expected to transition to CME Globex. Also under the terms of the agreement, CME Globex will be the exclusive electronic trading platform for metals products currently listed on the COMEX Division, with an anticipated third quarter launch.

All NYMEX contracts traded on CME Globex will be cleared by the NYMEX clearinghouse. In addition to NYMEX liquidity providers, a specified number of CME market makers will be designated by CME to build electronic liquidity at NYMEX member rates. Additional terms of the agreement were not disclosed.

From June 2002 through November 2005, NYMEX miNYTM crude oil and natural gas futures contracts were available on CME Globex as part of a previous service agreement between the two exchanges. Floor trading of NYMEX’s energy contracts has increased 28.3% since 2003. Electronic trading on NYMEX ClearPort® and NYMEX ACCESS® averaged 330,280 contracts per day during the first quarter of 2006, an increase of 128% over the same period in 2005.
