ICE, NGX Open Cleared Physical Markets to OTC Broker Facilitation

    Three Additional Hubs to be Added for Physical Clearing on August 5

    CHICAGO and CALGARY, July 10 /CNW/ - IntercontinentalExchange, Inc.
(NYSE:  ICE) and Natural Gas Exchange Inc. (NGX), a wholly owned subsidiary of
TMX Group Inc. (TSX:X), today announced plans to provide deal entry capability
to energy brokers for physically cleared OTC natural gas contracts.
    Under this arrangement and effective immediately, energy market
participants who are ICE and NGX customers may designate specific brokerage
firms to enter physical transactions for clearing through NGX utilizing the
ICEBlock(sm) system. As part of the ICE/NGX alliance announced last year,
physical clearing services are currently offered at three U.S. hubs: GTN
Malin, PG&E Citygate and Henry Hub. Physical product clearing services will be
added for Panhandle Eastern Pool, NGPL TxOk East and Northern Natural's Demarc
on August 5, 2008. Volumes at these hubs have grown steadily each month since
physical clearing services were initiated in March 2008 as a result of new
participants and increased liquidity at the hubs.
    "This arrangement provides approved brokers with direct access to NGX's
physical clearing services on behalf of their clients," said NGX President
Peter Krenkel. "Broker participation will allow NGX to grow open interest and
will provide brokers with another tool to close physical deals between
credit-constrained counterparties."
    "The ICEBlock system was designed to allow direct broker input and has
proven to be an effective tool," said Chuck Vice, ICE President and Chief
Operating Officer. "We introduced our innovative financial clearing solution
for energy products in 2002, and NGX introduced physical clearing over a
decade ago. In that time, customers have benefited from the removal of
counterparty credit risk in bilateral transactions, and the resulting
liquidity by expanding these markets."
    NGX's effective clearing and settlement model has achieved unparalleled
success in facilitating physical energy transactions, giving Canada
exceptional liquidity in its physical gas markets. NGX has enabled more than
$400 billion of physical gas transactions since its inception in 1994. In
2007, over 8.8 trillion cubic feet of natural gas was traded on NGX.
    Brokerage firms interested in physically cleared OTC natural gas
contracts must execute an ICE Broker Agreement in order to qualify and be
registered with ICE as an enabled broker. For more information, please contact
ICE's Jeff Rosenzweig at (646) 733-5005 or NGX's Matt Frye at (832) 978-9835.
