                 ISONICS CORPORATION SIGNS AGREEMENT TO ACQUIRE
                   INTERNATIONAL PROCESS RESEARCH CORPORATION

SAN  JOSE,  CA  (April  29,  1998) . . . . .  Isonics  Corporation  (OTC:  ISON)
announced  today that it has signed a definitive  agreement  to acquire  Golden,
CO-based International Process Research Corporation (Interpro), a privately held
company,  in exchange for 354,000 restricted shares of Isonics common stock. The
transaction  is expected  to close  within the next month  subject to  customary
closing  conditions.  According to the announcement by Isonics President and CEO
James E. Alexander,  the Interpro  acquisition is a key element in the Company's
expansion  strategy.  It will  provide  Isonics  with  in-house  processing  and
manufacturing  capabilities  for its core-market  depleted zinc (DZ) product and
for developing  enriched isotopes for other applications,  including  diagnostic
breath tests and imaging for the healthcare market.

         Interpro,  which has been doing business as Colorado  Minerals Research
Institute, is a contract research, process development, and materials processing
operation  with 25  employees.  Results  for its year ended  December  31,  1997
reflected  sales of $2.3 million with revenue for the first calendar  quarter of
1998 exceeding  $900,000.  Interpro will operate as a wholly owned subsidiary of
Isonics from its current  location which includes  office,  laboratory and pilot
plant  facilities  as well as ample room for  expansion.  Further terms were not
disclosed.

         James E. Alexander Isonics' President commented, "Interpro has been the
primary  supplier of  processing  services  for our core DZ product for the past
five  years."  DZ is used as an  additive  in  nuclear  power  plants  to reduce
corrosion and cracking of key  components  and to reduce  radiation  exposure to
plant workers.  Alexander went on to state,  "The  acquisition of this important
supplier is a logical step in the continued growth and development of Isonics as
we drive to bring more  valued-added  manufacturing  under our  direct  control.
Interpro adds revenue,  profits,  a talented  management team and a skilled work
force to Isonics.  It provides an  infrastructure  platform for  expansion  into
domestic  production of stable isotopes,  such as carbon-13 and for valued-added
processing  of a range of high  purity  materials.  Interpro  is the  first of a
number of business and  technology  acquisitions  the Company  intends to pursue
which are designed to shift  manufacturing  focus from Russia and Georgia to the
United States and Europe."

         Interpro Owner and President Robert H. Cuttriss,  Ph.D., noted, "Having
worked closely with Isonics for years,  we have gained a good  understanding  of
their  commitment  to the  development  of advanced  materials and chemicals and
their considerable opportunities in the isotope marketplace.  The combination of
these  factors  with the  strategic  and  operational  benefits of the  Interpro
organization  and  facilities  make this  acquisition  an excellent  vehicle for
future growth."

         Isonics is a specialty  chemical and advanced  materials  company which
develops and commercializes  products based on enriched stable isotopes.  Stable
isotopes can be thought of as ultra-ultra  pure  materials.  This high degree of
purification  provides  enhanced  performance   properties  compared  to  normal
materials.  Stable  isotopes have  commercial  uses in several areas,  including
energy; research, medical diagnostics, and drug development; product tagging and
stewardship; semiconductors; lasers; and optical materials.
