             HEARTLAND TECHNOLOGY ANNOUNCES RECEIPT OF 'PUT NOTICE'


CHICAGO, May 2 /PRNewswire-FirstCall/ - Heartland Technology, Inc. (Amex: HTI -
news) announced today that it has received a "put notice" from LZ Partners, LLC
(LZ) demanding that Heartland Technology buy back LZ's shares in Zecal
Technology, LLC. The notice cites an amount of $12.8 million plus interest dated
as of April 16, 2002. Zecal is a joint venture of the two companies that has
ceased operations.

Heartland Technology also has received resignations from LZ's two members of the
board of managers of Zecal.

Heartland Technology said it is reviewing the put notice to determine what
action to take.

The company recently reported that it is not currently generating enough cash
from operations to pay fixed costs. Heartland Technology said it was in
discussions with its creditors to see if it can reach agreements to restructure
its debt. The company also said it was seeking to sell or merge various assets
and subsidiaries as well as the entire company in order to create value. If
Heartland Technology is unsuccessful in these efforts, the company is likely to
be dissolved or liquidated.
