IntercontinentalExchange Announces Acquisition of Climate Exchange

ATLANTA and LONDON, April 30, 2010 - **Climate Exchange's Emissions Markets Complement ICE's Leading
Integrated Futures and OTC Markets**

IntercontinentalExchange (NYSE: ICE), a leading operator of regulated
global futures exchanges, clearing houses and over-the-counter (OTC) markets,
today announced that it has agreed on terms to acquire Climate Exchange plc
(Climate Exchange or CLE), a leader in the development of traded emissions
markets. Climate Exchange operates the European Climate Exchange (ECX), the
Chicago Climate Exchange (CCX) and the Chicago Climate Futures Exchange
(CCFE).

Under the terms of the acquisition, Climate Exchange shareholders will
receive 7.50 pounds Sterling in cash for each share in Climate Exchange held
at today's date, valuing the entire existing issued and to be issued share
capital of Climate Exchange at approximately 395 million pounds (US$604
million(1)). The transaction consideration will include US$220 million that
has been drawn from ICE's existing credit facilities for these purposes(2)
and the remainder from existing cash resources. The transaction is expected
to be accretive to earnings in 2011 and slightly dilutive to earnings for the
balance of the current year(3) following an anticipated closing at the end of
July 2010. ICE, through its wholly-owned subsidiary IntercontinentalExchange
Holdings, acquired a 4.8% stake in CLE on June 22, 2009 for 6.45 pounds a
share. Additional details will be provided upon the completion of the
transaction, at which time Climate Exchange will be a wholly-owned subsidiary
of ICE, operating under the Climate Exchange's respective brand names.

"The combination of Climate Exchange's emissions markets and ICE's
futures and OTC energy markets is an important and logical strategic
combination for our customers and shareholders, and clearly an exciting
opportunity for ICE to grow and further diversify our revenues," said ICE
Chairman and CEO Jeffrey C. Sprecher. "ICE has been a partner with Climate
Exchange and Dr. Sandor since 2003, and we have worked together toward the
development and expansion of the emissions markets. The leadership that
Climate Exchange has shown in establishing market standards in Europe, and
increasingly the U.S. and Asia, has driven its success, and we see continued
growth opportunities within these nascent markets globally."

"The development of our Company from initial concept to its leadership
role in global environmental markets is a tribute to the vision and efforts
of our entire team. We believe that a combination with ICE makes strategic
sense and look forward to addressing continued opportunities together," said
Climate Exchange's Chairman Richard Sandor. "ICE has committed to further
developing the Climate Exchange businesses and building on our joint track
record of innovation and success to the benefit of our customers across
futures and OTC markets in Europe, Asia and the U.S."

ICE and its affiliates currently have multiple contracts in place with
Climate Exchange and its affiliates to provide technology and clearing
services. These contracts include a cooperation and licensing agreement
whereby ICE provides an electronic trading platform and clearing to ECX for
European emissions trading, a licensing technology agreement whereby ICE
provides an electronic trading platform to CCX for U.S. emissions trading and
a clearing services agreement whereby ICE provides clearing for CCX's U.S.
emissions markets. Pursuant to these contracts, ICE charges fees to Climate
Exchange for the services provided and shares in the revenue with respect to
the trading and clearing of emissions contracts.

The transaction is subject to relevant regulatory approvals. Morgan
Stanley advised ICE on the transaction and Shearman & Sterling LLP served as
ICE's legal advisor.
