Forward Looking Statements & Non-GAAP Measures

The following presentation contains forward-looking information based on the current expectations of Terex Corporation. Because forward-looking statements involve risks and uncertainties, actual results could differ materially. Such risks and uncertainties, many of which are beyond the control of Terex, include among others: our business is highly cyclical and weak general economic conditions may affect the sales of its products and its financial results; our business is sensitive to fluctuations in interest rates and government spending; the ability to successfully integrate acquired businesses; the retention of key management personnel; our businesses are very competitive and may be affected by pricing, product initiatives and other actions taken by competitors; the effects of changes in laws and regulations; our business is international in nature and is subject to changes in exchange rates between currencies, as well as international politics; our continued access to capital and ability to obtain parts and components from suppliers on a timely basis at competitive prices; the financial condition of suppliers and customers, and their continued access to capital; our ability to timely manufacture and deliver products to customers; possible work stoppages and other labor matters; our debt outstanding and the need to comply with restrictive covenants contained in our debt agreements; our ability to maintain adequate disclosure controls and procedures, maintain adequate internal controls over financial reporting and file its periodic reports with the SEC on a timely basis; the previously announced investigations by the SEC and the Department of Justice; compliance with applicable environmental laws and regulations; product liability claims and other liabilities arising out of our business; and other factors, risks, uncertainties more specifically set forth in our public filings with the SEC. Actual events or the actual future results of Terex may differ materially from any forward looking statement due to those and other risks, uncertainties and significant factors. The forward-looking statements speak only as of the date of this presentation. Terex expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement included in this presentation to reflect any changes in expectations with regard thereto or any changes in events, conditions, or circumstances on which any such statement is based.

Non-GAAP Measures: Terex from time to time refers to various non-GAAP (generally accepted accounting principles) financial measures in this presentation. Terex believes that this information is useful to understanding its operating results and the ongoing performance of its underlying businesses without the impact of special items.

Positioned for Continuing Long - Term Trends

LONG TERM OUTLOOK

* Source: International Energy Agency, Oil Price is average global price, Coal futures price is the NYMEX contract for Central Appalachian Coal

• Near term commodity price volatility is challenging, as lower anticipated consumption brings down prices, impacting short term production levels

• Robust long term outlook for energy remains – driven by advancing consumption in the developing world and continued demand elsewhere

• Terex is well positioned to capitalize in Cranes, Mining, and Other businesses

OPEX* CAPEX*

• Recent aggressive investment in global commodities will likely slow near term, but leading producers remain committed to expanding capacity

• Per capita commodity consumption in developing countries remains well below developed country norms and will continue to increase over time

• This trend directly benefits Terex in Mining, Materials Processing, and other businesses that sell equipment into the mining industry

*Source: PWC: “Mine: As Good as it Gets?”, 2008 – capex excludes acquisitions
