Terex Corporation Awarded Multi-Year Mining Contract From Rio Tinto

April 26, 1999

WESTPORT, CT, April 26,1999 - Terex Corporation (NYSE: TEX) today announced that it has entered into a multi-year supply contract with Rio Tinto for the sale of Terex Mining's rear dump surface mining trucks. Rio Tinto is one of the world's leading international mining groups. The Group operates over 43 open pit mines worldwide. Rio Tinto's substantial interests in mining include copper, gold, iron ore, coal, aluminum, borates and titanium dioxide feedstock.

"We are very pleased that Unit Rig was awarded this very important contract," commented Ronald M. DeFeo, Terex's Chairman and Chief Executive Officer. "Under this supply agreement, Unit Rig has been granted a minimum market share for all new trucks purchased by Rio Tinto mines over the next five years. The market share agreement has a potential value of $100 million over the five-year period and we have already received initial orders as a result of this agreement. More importantly, this award creates franchise value and reinforces our strategy of building a competitive and global mining enterprise. This contract also provides our mining group with a growing base of business well beyond 1999."

"This order is very significant for several reasons," said Ernie Verebelyi, President of Terex Earthmoving. "It comes on the heels of a $100 million multi-year mining order from Cleveland-Cliffs and follows the very successful Coal India contract signed late last year. It further enhances the position of our mining business within the industry as a supplier of choice."
