NYMEX Holdings and Montreal Exchange Announce Strategic Partnership

Wed Feb 14 2007

( NEW YORK & MONTREAL, February 14, 2007 — The New York Mercantile Exchange, Inc. (NYMEX), a subsidiary of NYMEX Holdings, Inc. (NYSE:NMX), the world's largest physical commodity exchange, and the Montreal Exchange (MX), Canada's financial derivatives exchange, today announced their intention to form a strategic alliance that will include NYMEX purchasing a 10% stake of MX and the creation of a joint venture company that will serve the Canadian energy industry.

The proposed joint venture between NYMEX and MX will create a new Canadian corporation, headquartered in Calgary, Alberta, that intends to provide trading and clearing of exchange–traded and over–the–counter crude oil, natural gas, and electricity products with a focus on the Canadian markets.

As part of the proposed alliance, NYMEX will have the right to designate one nominee for election to the MX Board of Directors. Consummation of the proposed transaction is subject to a number of conditions including finalization of due diligence and documentation and other closing conditions. The closing date is dependent on those conditions but could be as early as March 7, 2007.

NYMEX Chairman Richard Schaeffer said, "NYMEX is pleased to partner with the Montreal Exchange, a leader in the Canadian financial industry, to better serve the Canadian marketplace. Canada is a major center in the global energy markets, and we intend to fill the risk management gap that currently exists with the introduction of Canadian energy contracts."

"We have been planning to build a joint venture to serve the Canadian energy sector and now we have found the ultimate strategic partner, NYMEX," said Luc Bertrand, President and Chief Executive Officer of the Montreal Exchange. "NYMEX is a global leader with in depth knowledge of energy trading and clearing. MX is a leader in developing the Canadian financial derivatives market. We believe the new company will be in a unique position to serve the market and, in Canada, Calgary is the natural location for this business."

The joint venture has a two–phase business plan. First, the partners intend to offer clearing services to participants in OTC energy markets. The focus will be on both financial and physical contracts based primarily on Canadian energy commodities. In the second phase, the joint venture intends to develop and market on–exchange futures and options contracts on the same underlying commodities. It intends to employ the services of the two partners to benefit from economies of scale and lower operational costs.
