NYMEX and Other Major Market Participants to Form The Green Exchange™,
The World’s Most Comprehensive Environmental Marketplace
NYMEX Leads Venture with Evolution Markets, Morgan Stanley, Credit Suisse,
JPMorgan, Merrill Lynch, Tudor Investment Corp., ICAP, and Constellation Energy
New Exchange Will Offer Contracts for Carbon, Renewable Energy, and Other
Major Environmental Commodities

New York, N.Y., December 12, 2007 -- NYMEX Holdings, Inc. (NYSE:NMX), the parent
company of the New York Mercantile Exchange, Inc. (NYMEX), the world’s largest physical
commodity futures and options exchange, today announced the formation of The Green
Exchange™ venture, with Evolution Markets Inc., Morgan Stanley Capital Group Inc., Credit
Suisse, JPMorgan, Merrill Lynch, Tudor Investment Corp., ICAP and Constellation Energy. The
new exchange will offer a comprehensive range of environmental futures, options, and swaps
contracts for markets focused on solutions to climate change, renewable energy, and other
environmental challenges.

The Green Exchange products are expected to begin trading during the first quarter of 2008 and
will be cleared by NYMEX. The Green Exchange venture is expected to launch as a U.S.
Commodity Futures Trading Commission (CFTC)-regulated exchange during the first quarter of
2009, pending regulatory approval.

NYMEX Chairman Richard Schaeffer said, “The broad slate of new environmental products will
perfectly complement NYMEX’s energy complex, enabling The Green Exchange customers to
efficiently manage the cost of reducing their ‘carbon footprint.’ The Green Exchange expects to
focus on both global and regional compliance trading while also building liquidity and demand
for the highest quality voluntary standards in the market. Underlying all this will be the ability for
all market participants to manage risk and take positions in environmental derivatives markets.”
Initially, The Green Exchange intends to offer trading in global carbon-based contracts, such as
carbon allowances (EUAs) under the European Union Emissions Trading Scheme, carbon credits
(CERs) under the U.N. Clean Development Mechanism, and verified greenhouse gas emission
reductions (VERs/VCUs) used in accordance with voluntary carbon standards. The Green
Exchange will also offer contracts for U.S. SO2 and NOx emissions allowance trading programs,
as well as contracts for national Green-e™ certified voluntary renewable energy certificates
(RECs).

 

Evolution Markets President and Chief Executive Officer Andrew Ertel said, “Leveraging
financial markets is an essential part of addressing environmental challenges such as global
warming, and The Green Exchange is the right financial marketplace at the right time. We’ve
identified a set of contracts that address climate change, encourage renewable energy
development, and tackle air quality. The Green Exchange will be more than a financial
marketplace. It will be an engine behind global efforts to improve the environment.”
Nancy King, Managing Director and Head of U.S. Emissions at Morgan Stanley, said, “We
believe the global emissions markets represent huge growth potential and are excited to be part of
the development of this important exchange.”

NYMEX, Evolution Markets, and their partners have worked extensively with utilities,
investment banks, environmental brokers, environmental groups, and institutional asset managers
to establish a set of contracts that enable market participants to effectively manage risk and gain
direct exposure to the global carbon market and other U.S. environmental markets. The group
has also consulted with environmental groups to select the highest quality voluntary carbon and
renewable energy offset standards as the basis for products.

Paul Tudor Jones, founder of Tudor Investment Corp., said, “Tudor Investment is thrilled at the
historic opportunity to join with NYMEX and our partners to launch The Green Exchange, in
order to provide financial market participants with high quality and liquid green products in order
to achieve the larger goal of harnessing market forces to improve the environment in the years
and decades ahead.”

Paul Ezekiel, Managing Director and Head of Environmental Markets at Credit Suisse, said,
“Credit Suisse is excited to support the development of an exchange with first-class
environmental market products and clearing capabilities. The Green Exchange is very well
positioned to facilitate the continued growth of the global environmental markets, including the
anticipated rapid growth of these markets in the United States.”
Blythe Masters, Managing Director and Head of Global Commodities at JPMorgan, said, “The
Green Exchange proves NYMEX to be the change agent that our environment and our energy
markets badly need.”

David Sobotka, Head of Fixed Income, Currencies and Commodities at Merrill Lynch, said, “We
are excited to be a founding partner alongside NYMEX and others in The Green Exchange, a
platform which will support global environmental trading and facilitate forecasted growth in this
important asset class.”

The Green Exchange venture is in discussions with additional strategic partners from a broad
cross section of market participants including banks, brokers, hedge funds, and energy and
industrial corporations. It anticipates announcing additional strategic partners in the near future.
Products will be listed for trading on the CME Globex® electronic trading platform and for
clearing on the NYMEX ClearPort® platform. All contracts will be cleared through the NYMEX
clearinghouse as regulated futures contracts. In order to ensure broad global market participation,
The Green Exchange will have:

• Established links with NYMEX clearing and trading platforms to provide market
participants the opportunity to cross-hedge risk and cross-margin positions between
established energy and emerging environmental markets;
• Opportunities for all market users to earn equity in the Green Exchange venture by
helping to create liquid and transparent markets in its products; and
• Highly competitive transaction fees.
In keeping with its mission to assist in protecting the environment through market-based
approaches, The Green Exchange venture intends to offset all of its electricity use with Green-e™
certified renewable energy credits, and intends to offset its remaining non-power related carbon
emissions through the purchase of voluntary carbon credits, making the exchange fully carbon
neutral.
