close in the fourth quarter of 2007, will be CHF 30 million, or
approximately U.S. $25 million.

"We are excited to be combining the capabilities of CF Industries
and KEYTRADE. CF Industries has had a long, constructive relationship
with Melih Keyman, the chairman and chief executive officer of
KEYTRADE, and with his partners and team," commented Stephen R.
Wilson, chairman and chief executive officer of CF Industries
Holdings, Inc.

"We look forward to working together to expand our businesses for
the benefit of all our shareholders. This strategic partnership
provides CF Industries with a global platform from which to pursue our
objectives of growth and diversification," Wilson added.

"From KEYTRADE's perspective, this partnership will help ensure

partner, we believe that KEYTRADE will be able to serve the needs of
our trading partners much better with wider product support,"
commented Melih Keyman, chairman and chief executive officer of

"We, too, are excited at the prospect of combining our global
trading system with CF Industries' strong production base and
international aspirations," Keyman added.

Keyman, a founder of KEYTRADE, will continue as CEO of the company
and will run the organization on a day-to-day basis together with his
founding partners Andreas Vaterlaus, Sergei Rudakov, and Yang Baoheng.

KEYTRADE, founded in 1997, buys fertilizer, primarily nitrogen
products but also phosphate and potash, in 35 countries and markets it
in 65 countries. The company has extensive commercial relationships in
both fertilizer supply and market regions.

Initially, CF Industries will work exclusively with KEYTRADE to
export phosphate fertilizer and import UAN solution. The companies are
exploring additional opportunities to work together, including
sourcing other products to serve the North American market and
establishing production, distribution, and/or marketing presence in
attractive markets overseas.

Closing of the acquisition is subject to certain foreign
regulatory approvals and other customary closing conditions.
