Each American Eco common share issued after the record date will include one Right. The Rights will be attached to the common shares and will not be initially exercisable. Rights will become exercisable in the circumstances described in the Rights Plan, including ten days following the announcement that a person or group without prior approval from the Board of Directors has acquired, or obtained the right to acquire, beneficial ownership of 20 percent or more of the outstanding common shares, or ten days following the announcement of a takeover bid, tender offer or exchange offer. The Shareholder Rights Plan is in effect immediately and applies to acquisitions of shares after April 19th, 1998 subject to shareholder approval. In certain circumstances, the Rights may be redeemed by the Company at a price of $0.0001 per Right. If not redeemed, the Rights will expire in ten years, subject to periodic approval by shareholders. A summary of the Rights Plan will be mailed shortly to the Company's shareholders in connection with the Proxy material for the 1998 Annual and Special Meeting and is available upon request from the Company and will be filed with the appropriate regulatory agencies.
