FOR IMMEDIATE RELEASE

FANT URGES HEI BOARD TO HOLD SPECIAL MEETING PROMPTLY
- -----------------------------------------------------

NEW YORK, NEW YORK - May 20, 1998 - In a letter to the Board of Directors of
HEI, Inc. (Nasdaq: HEII) of Victoria, Minnesota, Anthony J. Fant urged the
Board to promptly hold the special meeting of shareholders that he demanded
nearly two weeks ago. The Board has failed so far to call the special meeting
to remove obstacles to Fant's $8.00 per share cash tender offer. Among other
things, HEI shareholders will vote on replacing the current directors (other
than Eugene Courtney) with Fant's slate.

"We want to consummate the offer now," Mr. Fant said. "We see a window of
opportunity to initiate growth now," he added. "We urge the Board to end its
campaign of delay. Stop standing in the way of the shareholders' ability to
have their say and make their choice. Hold the special meeting now and let
them decide."

Mr. Fant's letter urges the Board to hold the special meeting in early June
and not push it back to the last permissible date.

Mr. Fant and Fant Industries Inc. mailed on April 23, 1998, a proxy statement
and related materials to HEI's shareholders to solicit proxies to be used at
this special meeting. The proxy solicitation was preceded by an $8.00 per
share cash tender offer commenced by Fant Industries on March 10, 1998 to buy
an additional 11.5% of the Common Stock of HEI.

Fant Industries has retained Beacon Hill Partners, Inc. for solicitation and
advisory services.
