MCGINNIS, CHAIRMAN, PRESIDENT & CEO OF AMERICAN ECO CORPORATION announced today that as the first step in a proposal to acquire Dominion Bridge Corporation of Montreal, Quebec, following completion of the purchase of a private placement of USD$5.0 million in shares and warrants of Dominion Bridge, he has accepted appointments to the Board of Directors and to the Executive Committee of Dominion Bridge. Unanimous approval of an American Eco Letter of Intent to acquire Dominion Bridge, was given upon the recommendation of Legg Mason Wood Walker, Incorporated. The final transaction will be subject to ratification of the Boards of both companies, execution of a definitive acquisition agreement, approval of the shareholders of both companies, as well as approval of requisite regulatory authorities and customary closing conditions. In the proposed acquisition transaction, the shareholders of Dominion Bridge would receive, three year, 7-1/2% convertible subordinated notes ("Notes") of American Eco in the principal amount of USD$3.00 per each common share of Dominion Bridge. At the end of each six-month period, holders may convert one-third of the Notes into shares of American Eco common shares at a price of USD$15.00 per share.

The Notes will bc registered and tradable on a nationally recognized securities exchange. The transaction is valued at approximately USD$135.0 million including the third party bank debt of Dominion Bridge Corporation of USD$37.5 million. The valuation of Dominion Bridge Corporation is based on the significant synergies between the operating units of both companies in North America.

The significant engineering and construction expertise of Dominion Bridge Corporation's 63% owned subsidiary, McConnell Dowell, complements American Eco's business strategy. The Letter of Intent includes a USD$25.0 million working capital loan to be made available to Dominion Bridge by March 23, at which time, American Eco will also provide management services to Dominion Bridge. Concurrently, Dominion Bridge will issue a two- year warrant to American Eco entitling American Eco to purchase up to 10% of the outstanding common shares of Dominion Bridge at USD$3.00 per share.

The Letter of Intent terminates if definitive agreements providing for the contemplated transactions are not executed by April 6, 1998.
