ATLANTA, July 8, 2010 - IntercontinentalExchange (NYSE: ICE), a leading operator of regulated

today, July 8, 2010.

Under the previously announced terms of the acquisition, Climate Exchange
shareholders will receive 7.50 pounds Sterling in cash for each share of
Climate Exchange, valuing the entire existing issued and to be issued share
capital of Climate Exchange at approximately 395 million pounds (US$597
million). Transaction consideration included US$377 million from ICE's
existing cash resources and US$220 million from ICE's existing credit
facilities. Climate Exchange is now a wholly-owned subsidiary of ICE,
operating under Climate Exchange's respective brand names.

"ICE's acquisition of Climate Exchange is the culmination of a
long-standing and productive partnership between our companies," said ICE
Chairman and CEO Jeffrey C. Sprecher. "With a track record of developing
innovative, market-based solutions for emissions markets, Climate Exchange is
a natural partner and complements our global energy business. Moving forward
together, we will continue working to address the opportunities in the
evolving emissions markets."

"This is a great moment for Climate Exchange stockholders and customers -
and for the future of emissions markets as we move forward with greater scale
and additional resources," said Richard Sandor, founder of Climate Exchange.
"I look forward to working closely with ICE's leadership to realize the full
potential of our global emissions markets."

Key benefits of ICE's acquisition of Climate Exchange are expected to
include:

    - Leverages productive, long-term global partnership across
      technology, clearing and operations;
    - Increased scale, distribution and cross-selling opportunities;
    - Diversification of ICE's products, customers and geographic
      profile;
    - Cost savings and efficiencies across technology, clearing and
      product-development;
    - Capital efficiency, product development opportunities and shared
      European and U.S. utilities market customers;
    - Early-stage growth markets with long-term potential, including
      emissions programs in additional markets globally; and
    - Exposure to nascent Asian commodities marketplaces with 25% stake
      in Tianjin Climate Exchange.

The Climate Exchange is organized into three core businesses: the
European Climate Exchange (ECX), the Chicago Climate Futures Exchange (CCFE)
and the Chicago Climate Exchange (CCX). ICE has provided the electronic
trading platform for CCX and CCFE since the launch of trading on those
exchanges in 2003 and 2004, respectively. In 2005, ICE and Climate Exchange
co-developed and launched ECX, with contracts listed and traded on ICE
Futures Europe. In 2008, clearing for all ICE Futures Europe contracts,
including those of ECX, transitioned to ICE Clear Europe. In March 2009, ICE
acquired The Clearing Corporation, which is the clearing house for CCFE.

ECX operates a market for compliance certificates for the mandatory
European Emissions Trading Scheme (EU-ETS) and is one of the world's largest
and most developed environmental markets. In 2009, ECX average daily volume
(ADV) exceeded 20,000 contracts (20 million tonnes of carbon per day or 5.1
billion tones annually), up 82% from 2008. Year-to-date through June 30, ECX
ADV, which is already reflected in ICE Futures Europe ADV, was 27,153
contracts, an increase of 27% compared to the first six months of 2009. ECX
open interest stood at 947,158 contracts, up 9% compared to December 31,
2009.

CCFE is a Commodity Futures Trading Commission designated contract market
for regulated environmental products, including U.S. emissions such as sulfur
dioxide (SO2), nitrogen oxide (NOx) and Regional Greenhouse Gas Initiative
(RGGI) CO2 allowances. CCX is the world's first and North America's only
contractually binding, rules-based greenhouse gas emissions allowance trading
system.

    Financial Guidance Information

    - ICE expects to recognize transaction costs relating to the Climate
      Exchange acquisition of approximately US$1 million to US$2 million in
      the second quarter and US$6 million to US$7 million in the third
      quarter of 2010, which will be reflected in "acquisition-related
      transaction cost" and in GAAP earnings, and excluded from non-GAAP
      earnings.
    - ICE purchased a foreign exchange option to eliminate its exposure to a
      weakening U.S. dollar between the acquisition announcement and close
      dates. The subsequent strengthening of the dollar reduced the value of
      the hedge, and ICE will recognize a loss of US$14 million in the second
      quarter of 2010 below the operating income line in "other expense."
      This charge will be included in GAAP earnings and excluded from
      non-GAAP earnings.
    - As previously announced, ICE expects the transaction to be accretive to
      earnings in 2011, with negligible dilution for the remainder of 2010.
    - Total headcount at Climate Exchange is 66 employees in London, Chicago,
      New York and China.
    - Dr. Richard Sandor, founder of Climate Exchange, will serve as an
      advisor to ICE.
    - ICE will today post a brief merger presentation in the Investors &
      Media section of its website at www.theice.com.
    - Additional financial guidance will be provided on ICE's second quarter
      2010 earnings call on August 4; at that time, selected pro-forma
      financial information will be provided.
