          HEICO ANNOUNCES SALE OF ITS MEDITEK HEALTH CORP. SUBSIDIARY

         "PLANS FOCUS ON GROWTH AND ACQUISITIONS IN AEROSPACE BUSINESS"

HOLLYWOOD, FL -- HEICO CORPORATION (ASE:HEI), today announced that it has
reached an agreement to sell its Miami, FL-based MediTek Health Corporation
subsidiary to U.S. Diagnostic Labs, Inc. (NASDAQ symbol: USDL) for approximately
$23 million. Both MediTek and USDL are leading providers of medical diagnostic
imaging services through their outpatient facilities which offer Magnetic
Resonance Imaging (MRI), Computed Arial Tomography (CAT), Nuclear Medicine,
Ultrasound, Mammography and X-Ray services.

The MediTek divestiture reflects HEICO's decision to focus on its historical
and rapidly-growing aerospace businesses.

Laurans A. Mendelson, HEICO's Chairman, President and Chief Executive Officer,
stated, "HEICO intends to aggressively pursue further acquisition opportunities,
paying particular attention to the growing aerospace industry where we have had
great success."

HEICO announced earlier this month that it had entered into a letter of intent
to acquire Trilectron Industries, Inc., a leading designer and manufacturer of
aircraft ground support equipment.

Mr. Mendelson added, "We believe there are numerous opportunities whereby we
can acquire manufacturers in segments, such as aircraft parts and aircraft
ground support equipment manufacturing, allowing HEICO to achieve substantial
operating synergies by combining entities and creating a significant industry
market force in the same manner as it did with MediTek."

Consideration for the MediTek transaction consists of $13 million in cash and a
$10 million face value five-year note bearing interest at 6.5% per annum
convertible into 1,081,081 USDL common shares.

The agreement calls for Mr. Mendelson to join USDL's Board of Directors. As part
of the transaction, Joseph A. Paul, MediTek's President, will become President
of USDL and most of MediTek's senior management will join USDL. USDL said that
it does not presently anticipate employment changes at MediTek's facilities.

The transaction is anticipated to result in an after-tax gain of approximately
$5 million, (or $1.00 per share), during HEICO's third quarter of fiscal 1996
and is expected to close by July 1, 1996. In addition, the convertible nature of
the note will provide HEICO the opportunity to continue to participate in
upside growth in the medical imaging industry. Closing is subject to execution
of a definitive purchase agreement, which is expected within the next week, and
customary closing conditions.

Mr. Mendelson commented, "During the past six months, HEICO has considered
numerous partnership and acquisition possibilities for MediTek, but concluded
that today's sale to USDL offered HEICO and its shareholders a superior return
on its investment. We are impressed with USDL's management and its operating
strategies and believe that it will soon become this country's dominant
diagnostic imaging provider."

HEICO Corporation is engaged in the aerospace industry through its Hollywood,
FL-based HEICO Aerospace Corp. subsidiary and in the health care industry
through its Miami, FL-based MediTek Health Corp. subsidiary.
