FOR IMMEDIATE RELEASE

Three Out of Four Proxy Advisory Firms Recommend Terra Shareholders Vote “FOR” All Three Terra Director Nominees on the WHITE Proxy Card

Terra Comments on RiskMetrics Report

SIOUX CITY, IOWA (November 13, 2009) — Terra Industries Inc. (NYSE: TRA) today announced that three out of the nation’s four leading independent proxy advisory firms, Glass Lewis & Co., PROXY Governance, Inc. and Egan-Jones Proxy Services, recommend that their clients vote the WHITE proxy card FOR Terra’s directors via mail, telephone, Internet, or at Terra’s November 20, 2009 Annual Meeting.

Terra issued the following statement in response to a report issued by RiskMetrics Group (formerly Institutional Shareholder Services) regarding the election of directors at Terra’s November 20, 2009 Annual Meeting:

We strongly believe that RiskMetrics reached the wrong conclusion in failing to recommend that shareholders re-elect Terra’s highly-qualified and independent directors. CF Industries Holdings, Inc.’s (NYSE: CF) proposal significantly undervalues Terra’s near term and long term prospects, and ignores the significant upside in Terra’s strategy as the economic recovery continues. As we have repeatedly said, CF has had ten months to put a compelling offer on the table, yet its current proposal continues to be inadequate, opportunistic and not in the best interests of Terra shareholders. We note RiskMetrics’ acknowledgment that “[g]iven the significant gap (almost $200 million) between the Street consensus 2010 EBITDA estimates and management projections, a more nitrogen bullish investor who buys into the management outlook could potentially value the company even higher, implying an even lower premium.”

Terra shareholders have an investment in a company that has consistently delivered value, including more than $1 billion in share buybacks and dividends over the past four years. While RiskMetrics’ decision may reflect its clients short term focus, we are confident that our shareholders understand the strong investment proposition they have in Terra.

The Company urges shareholders to vote the WHITE proxy card FOR Terra’s experienced directors — Martha O. Hesse, Dennis McGlone, and Chairman, Henry R. Slack — directors who have the independence, industry knowledge, and experience to guide Terra through whatever may emerge as this process continues, with a singular focus on what is in the best interests of all Terra shareholders.

Our opinion remains that CF’s proposal is inadequate and opportunistic. Terra’s Board has always been and continues to be vigilant in the oversight of its fiduciary duties to shareholders, and remains open to considering any bona fide opportunity that creates meaningful value for all

NEWS from Terra Industries Inc. November 13, 2009

Terra shareholders. We believe that CF’s nominees, if elected, would work to advance CF’s interests and its inadequate proposal at the expense of Terra shareholders.

Terra shareholders are reminded that their vote is important, no matter how many shares they own. Whether or not they attend the Annual Meeting, Terra shareholders are encouraged to submit a WHITE proxy by Internet, telephone or by signing and dating the WHITE proxy card itself and returning it as soon as possible.

Any Terra shareholders who have questions or require assistance voting their shares should contact MacKenzie Partners, Inc., which is assisting Terra in this matter, at (800)-322-2885.
