Microphonics' Indy Participation Receives National Exposure

24 May 1999

    NASHVILLE, Tenn., May 24 -- Microphonics
(OTC Bulletin Board: MRPS) http://www.microphonics.com announces, because of limited
practice time by driver Brian Tyler due to weather, the #36 Microphonics
Delco-Remy car did not make a qualifying attempt for this year's race.  Prior
to the weekend's activities, however, Microphonics became cosponsor of the #35
Prolong Lubricants Delco-Remy Microphonics Thermo Tech ISM team car.  This
car, driven by Steve Knapp, qualified with an average speed of 221.502 mph,
and will start 13th in the 33 car field.  The car was thoroughly checked prior
to its qualifying attempt with the Microphonics Model 111RCK to insure maximum
reliability and performance.  During the qualifying run the car performed
flawlessly.
    Jimmy Gayle, Microphonics CEO, commented "We are extremely pleased that
our INDY effort has led to greater exposure for Microphonics.  Our
shareholders will be pleased to know that our investment as  sponsor of an
INDY car, with the  Microphonics logo, has already resulted in significant
additional opportunities for Microphonics to expand it's product sales to
major companies within the automotive, industrial, transportation, and utility
sectors."
    Microphonics markets two proprietary hand-held Ultrasound devices - an
automotive device called the Microphonics Automotive Diagnostic System and the
Ultraphonic Detector that is designed for industrial and high performance
applications.
    The Automotive unit allows for highly accurate detection of leaks, engine
component wear such as valves and bearings, as well as electrical shorts and
drive train problems.  The unit is so precise that problems can be located
within 1/8th of an inch.  The Ultraphonic Detector shares the same qualities
and also has the unique ability to filter out ambient noises, thereby making
precise detection easy, even in the noisiest environments.
    One additional interesting fact.  The Microphonic devices also have
predictive failure ability.  In prior NASCAR tests, for example, the unit
correctly predicted 28 of 28 engine failures and the specific failure area(s)
where the problems would manifest themselves.  The company believes that
opportunities for safety applications are yet another significant area for the
Company to pursue.
