         This Current  Report on Form 8-K contains  forward  looking  statements
that involve  risks and  uncertainties  relating to the  acquisition  by Isonics
Corporation,  a California  corporation  ("Isonics"),  of International  Process
Research Corporation, a Colorado corporation ("Interpro"),  including the risks:
inherent in acquiring a company in Interpro's industry (e.g. assumption of known
and unknown liabilities, including environmental liabilites); that the synergies
expected  to result  from the  acquisition  described  below  might not occur as
anticipated;  and that management's  attention might be diverted from day-to-day
business activities.  Actual results and developments may differ materially from
those described in this Current Report.  For more information  about Isonics and
risks  relating to investing in Isonics,  refer to Isonics's most recent reports
on Form 10-QSB and Registration Statement on Form SB-2, as amended, Registration
No. 333-13289.

Item 2.  Acquisition or Disposition of Assets.

         On May 15, 1998, Isonics acquired Interpro by the acquisition of all of
the outstanding capital stock of Interpro from Metallurgy International, Inc., a
Nevada corporation ("Metallurgy").  The acquisition was accomplished pursuant to
a Stock Purchase Agreement dated as of April 30, 1998, among Isonics, Metallurgy
and Interpro (the "Purchase  Agreement").  In connection  with the  acquisition,
Isonics  issued  shares of its Common Stock in exchange for all of the shares of
Interpro  capital  stock  outstanding  on May 15, 1998.  The purchase  price was
arrived  at  through  arms-length  negotiations.  The total  number of shares of
Isonics  Common  Stock issued in  connection  with the  acquisition  was 353,982
shares. Of such shares,  176,991 shares are being held in escrow for one year to
secure the  obligations  of Metallurgy to indemnify  Isonics for any breaches of
the  representations  and  warranties  of  Metallurgy  and Interpro  made in the
Purchase Agreement. The acquisition will be accounted for as a purchase.

         Interpro,  which has been doing business as Colorado  Minerals Research
Institute, is a contract research, process development, and materials processing
operation.  Isonics  currently  intends to maintain  Interpro as a  wholly-owned
subsidiary and to have Interpro continue to conduct its business as historically
conducted.

                  A copy of the press  release  announcing  the  signing  of the
Purchase  Agreement  is  attached  hereto as Exhibit  99.1 and  incorporated  by
reference herein. A copy of the press release announcing the consummation of the
acquisition  is attached  hereto as Exhibit 99.2 and  incorporated  by reference
herein.

Income Security Act of 1974, as amended ("ERISA"), Part 3 of Title I of ERISA or

agreements; and

                  (vi)  an  accurate  and  complete  copy  of  the  most  recent

service  group" within the meaning of Section 414(m) of the Code. To the best of
the  Knowledge  of Seller,  the  Company  has never  made a complete  or partial
withdrawal from a  multiemployer  plan, as such term is defined in Section 3(37)
of ERISA,  resulting  in  "withdrawal  liability,"  as such term is  defined  in
Section 4201 of ERISA (without regard to subsequent  reduction or waiver of such
liability under either Section 4207 or 4208 of ERISA).

             (e) The Company does not have any plan or  commitment to create any
additional  Plan, or to modify or change any existing Plan (other than to comply
with applicable law) in a manner that would affect any Employee.

             (f) Except as set forth in Part 2.15(f) of the Disclosure  Schedule

coverage  provided  pursuant  to  Section  4980B  of  the  Code,  (ii)  deferred
compensation benefits accrued as liabilities on the Interim Balance Sheet, (iii)

benefits under any Plan that is an employee  welfare benefit plan (as defined in

Service, if required,  and neither the Company nor Seller is aware of any reason
why any such determination  letter should be revoked.

             (j) Except as set forth in Part 2.15(j) of the Disclosure Schedule,
neither  the  execution,  delivery or  performance  of this  Agreement,  nor the
consummation of the transactions  contemplated by this Agreement, will result in
any payment (including any bonus,  golden parachute or severance payment) to any
current or former Employee or director of the Company  (whether or not under any
Plan), or materially  increase the benefits payable under any Plan, or result in
any  acceleration  of the time of payment or vesting of any such  benefits.

             (k) Part 2.15(k) of the Disclosure  Schedule contains a list of all
salaried  employees  of the  Company  as of the  date  of  this  Agreement,  and
correctly  reflects,  in  all  material  respects,  their  salaries,  any  other
compensation payable to them (including  compensation payable pursuant to bonus,
deferred compensation or commission arrangements), their dates of employment and
their  positions.  The  Company  is not a  party  to any  collective  bargaining
contract or other Contract with a labor union involving any of its Employees. To

the Company has good labor relations, and none of the Company nor Seller has any
reason to believe that (i) the consummation of the transactions  contemplated by

relations,  or (ii) any of the Company's  employees  intends to terminate his or
her employment with the Company.

description of the basis on which Purchaser is terminating  this  Agreement.  If
the  Seller's  Agent  wishes to  terminate  this  Agreement  pursuant to Section
8.1(b),  Section 8.1(d) or Section  8.1(f),  the Seller's Agent shall deliver to
Purchaser a written notice  stating that the Seller's Agent is terminating  this
Agreement and setting forth a reasonably  detailed  description  of the basis on
which the Seller's Agent is terminating this Agreement.

         8.3 Effect of Termination.  If this Agreement is terminated pursuant to
Section 8.1, all further  obligations of the parties under this Agreement  shall
terminate; provided, however, that:

             (a) no party shall be relieved of any obligation or other liability
arising from any breach by such party of any provision of this Agreement; and

             (b) the parties shall, in all events,  remain bound by and continue
to be subject to the provisions set forth in Section 10.

         8.4  Nonexclusivity  of  Termination  Rights.  The  termination  rights
provided in Section 8.1 shall not be deemed to be  exclusive.  Accordingly,  the
exercise  by any party of its right to  terminate  this  Agreement  pursuant  to
Section 8.1 shall not be deemed to be an  election of remedies  and shall not be
deemed to prejudice, or to constitute or operate as a waiver of, any other right
or remedy  that such  party may be  entitled  to  exercise  (whether  under this
Agreement,  under any other  Contract,  under any  statute,  rule or other Legal
Requirement, at common law, in equity or otherwise).

                                      27.

             (a) The  representations  and warranties made by Seller  (including

Closing and shall expire on the first anniversary of the date of this Agreement;
provided,  however,  that if, at any time prior to the first  anniversary of the
date of this  Agreement,  Purchaser  (acting in good faith) delivers to Seller a
written notice  alleging the existence of an inaccuracy in or a breach of any of
the  representations  and  warranties  made by  Seller  (and  setting  forth  in
reasonable  detail the basis for  Purchaser's  belief that such an inaccuracy or
breach may exist) and asserting a claim for recovery  under Section 9.2 based on
such alleged inaccuracy or breach,  then the claim asserted in such notice shall
survive the first  anniversary  of the Closing  until such time as such claim is
fully and finally resolved.

             (b) All  representations  and  warranties  made by Purchaser  shall
terminate  and  expire  one year  from the date  hereof,  and any  liability  of
Purchaser with respect to such  representations  and warranties  shall thereupon
cease; provided, however, that if, at any time prior to the first anniversary of
the date of this Agreement,  Seller (acting in good faith) delivers to Purchaser
a written  notice  alleging the existence of an inaccuracy in or a breach of any
of the  representations  and warranties  made by Purchaser (and setting forth in
reasonable  detail the basis for  Seller's  belief  that such an  inaccuracy  or
breach may exist) and asserting a claim for recovery  under Section 9.3 based on
such alleged inaccuracy or breach,  then the claim asserted in such notice shall
survive the first  anniversary  of the Closing  until such time as such claim is
fully and finally resolved.

             (c) The representations,  warranties,  covenants and obligations of
Seller,  and the rights and remedies that may be exercised by  Purchaser,  shall
not be  limited  or  otherwise  affected  by or as a result  of any  information
furnished to, or any investigation  made by or knowledge of, Purchaser or any of
its Representatives. The representations,  warranties, covenants and obligations
of Purchaser, and the rights and remedies that may be exercised by Seller, shall
not be  limited  or  otherwise  affected  by or as a result  of any  information
furnished to, or any investigation made by or knowledge of, Seller or any of its
Representatives.

         9.2 Indemnification by Seller.

             (a)  Subject to Section  9.1(a),  Seller  shall hold  harmless  and
indemnify  Purchaser  from and  against,  and  shall  compensate  and  reimburse
Purchaser for, any Damages which are directly or indirectly suffered or incurred
by Purchaser or to which Purchaser may otherwise  become subject  (regardless of
whether or not such  Damages  relate to any  third-party  claim) and which arise
from or as a result of, or are directly or indirectly connected with:

                  (i) any  inaccuracy  in or  breach  of any  representation  or
warranty set forth in Section 2;

                  (ii) any breach of any covenant or obligation of Seller or the
Company set forth in this Agreement;

                                      28.

<PAGE>


                  (iii) any Legal Proceeding relating to any inaccuracy,  breach
or liability of the type referred to in clause "(i)" or "(ii)" above  (including
any Legal Proceeding  commenced by Purchaser for the purpose of enforcing any of
its rights under this Section 9).

             (b) Seller  acknowledges  and agrees that, if the Company  suffers,
incurs  or  otherwise  becomes  subject  to any  Damages  as a  result  of or in
connection  with any  inaccuracy in or breach of any  representation,  warranty,
covenant or obligation of Seller or the Company,  then  Purchaser  shall also be
deemed, by virtue of its ownership of the stock of the Company, to have incurred
Damages as a result of and in connection with such inaccuracy or breach.

             (c)  Seller  shall  not be  required  to make  any  indemnification
payment pursuant to Section 9.2(a) for any inaccuracy in or breach of any of its
representations  and  warranties  set forth in  Section 2 until such time as the
total amount of all Damages  (including the Damages arising from such inaccuracy
or breach  and all other  Damages  arising  from any  other  inaccuracies  in or
breaches  of any  representations  or  warranties)  that have been  directly  or
indirectly  suffered  or  incurred  by  Purchaser,  or to  which  Purchaser  has
otherwise become subject,  exceeds $40,000 in the aggregate. If the total amount
of such  Damages  exceeds  $40,000,  then  Purchaser  shall  be  entitled  to be
indemnified  against  and  compensated  and  reimbursed  all  Damages  incurred,
including such $40,000.

         9.3 Indemnification by Purchaser.

             (a) Subject to Section  9.3(b),  Purchaser  shall hold harmless and
indemnify  Seller from and against,  and shall  compensate and reimburse  Seller
for, any Damages which are directly or indirectly suffered or incurred by Seller
or to which Seller may otherwise  become  subject  (regardless of whether or not
such  Damages  relate to any  third-party  claim)  and which  arise from or as a
result of, or are directly or indirectly connected with:

                  (i) any  inaccuracy  in or  breach  of any  representation  or
warranty set forth in Section 3;

                  (ii) any breach of any covenant or obligation of Purchaser; or

                  (iii) any  Legal  Proceeding  relating  to any  inaccuracy  or
breach of the type  referred to in clause "(i)" or "(ii)" above  (including  any
Legal  Proceeding  commenced by Seller for the purpose of  enforcing  any of its
rights under this Section 9).

             (b)  Purchaser  shall not be required  to make any  indemnification
payment pursuant to Section 9.3(a) for any inaccuracy in or breach of any of its
representations  and  warranties  set forth in  Section 3 until such time as the

or breach  and all other  Damages  arising  from any  other  inaccuracies  in or
breaches  of any  representations  or  warranties)  that have been  directly  or
indirectly  suffered  or incurred by Seller,  or to which  Seller has  otherwise
become subject,  exceeds  $40,000 in the aggregate.  If the total amount of such
Damages exceeds $40,000, then Seller shall be entitled to be indemnified against

<PAGE>


         9.4 Satisfaction of Indemnification Claim; No Contribution.

             (a) From and  after  the  Closing,  the  escrow  under  the  Escrow
Agreement shall serve as security for the obligations  owed Purchaser under this
Section  9. Any  liability  (for  indemnification  or  otherwise)  to  Purchaser
following  the Closing  under this Section 9 may be satisfied by the delivery to
Purchaser,  from the shares escrowed  pursuant to the Escrow  Agreement,  of the
number of shares of  Purchaser  Common  Stock  determined  by  dividing  (a) the
aggregate  dollar  amount  of  such  liability  by (b)  $2.26  (as  adjusted  as
appropriate  to reflect any stock split,  reverse stock split,  stock  dividend,
recapitalization or other similar transaction  effected by Purchaser between the
date hereof and the date such liability is satisfied).

             (b) Except with respect to claims based on knowing and  intentional
misrepresentations of representations and warranties,  Purchaser agrees that the
sole  recourse of Purchaser  from and after the Closing with respect to a breach
by Seller of its  representations or warranties made in this Agreement or in the
Disclosure  Schedule  or the  other  indemnification  rights  set  forth in this
Section 9 shall be against the shares held in escrow under the Escrow Agreement.

             (c) Except with respect to claims based on knowing and  intentional
misrepresentations  or  representations  and warranties,  Seller agrees that the
sole  recourse  of  Seller  with  respect  to  a  breach  by  Purchaser  of  its
representations   or   warranties   made  in  this   Agreement   or  the   other
indemnification  rights set forth in this  Section 9 shall be  pursuant  to this
Section 9.

             (d) Seller waives,  and  acknowledges  and agrees that it shall not
have and shall not  exercise or assert (or  attempt to exercise or assert),  any
right of  contribution,  right of indemnity or other right or remedy against the
Company in connection with any indemnification obligation or any other liability
to which it may become subject under or in connection with this Agreement.

         9.5  Payment.  At such time as the  reimbursable  amount of a Claim (as
defined below) or a Third Party Claim (as defined below) has been  determined in
accordance with this Section 9 (a "Liquidated  Claim"),  the indemnifying  party
shall  immediately pay the Person to be indemnified  hereunder (an "Indemnitee")
the amount of the Liquidated Claim. No forbearance of an Indemnitee in demanding
payment  from the  indemnifying  party  shall act as a waiver of any right of an
Indemnitee to receive payment from the indemnifying  party, nor shall it relieve
the indemnifying party of any obligation to an Indemnitee under this Agreement.

         9.6  Notice of  Claims.  In the event an  Indemnitee  has any claim for
indemnification  under  Section  9.2 or Section 9.3 (a  "Claim"),  it shall give
prompt written notice thereof to the  indemnifying  party (Seller's Agent in the
case of Seller),  including in such notice a reasonably detailed  description of
the facts upon which such claim is based and the amount thereof.

         9.7 Disputed Claims. If the Indemnifying  Party objects to any Claim or
Third Party Claim, it shall give written notice of such objection and reasonably
detailed  statement  of the grounds of such  objection to  Indemnitee  within 30
business  days after notice is  received.  If no

                                      30.

<PAGE>


such  objection is given,  such Claim or Third Party Claim,  as the case may be,
shall be a  Liquidated  Claim.  If such  objection is made,  Indemnitee  and the
Indemnifying  Party shall meet and use their best  efforts to settle the dispute
in writing that when resolved shall be a Liquidated Claim.

         9.8 Defense of Third Party Claims.

             (a) If any third party shall notify an  Indemnitee  with respect to
any  matter  (a  "Third  Party  Claim")  that  may  give  rise  to a  claim  for
indemnification  against a party hereto (the  "Indemnifying  Party")  under this
Section 9, then the Indemnitee  shall  promptly  notify the  Indemnifying  Party
thereof  in  writing;  provided,  however,  that  no  delay  on the  part of the
Indemnitee in notifying the  Indemnifying  Party shall relieve the  Indemnifying
Party from any obligation hereunder, unless (and then solely to the extent that)
the Indemnifying Party is prejudiced.

             (b) The  Indemnifying  Party  shall  have the right to  defend  the
Indemnitee  against  the Third  Party  Claim with  counsel  of the  Indemnifying
Party's  choice  reasonably  satisfactory  to the  Indemnitee so long as (A) the
Indemnifying  Party notifies the Indemnitee  within 15 days after the Indemnitee
has given  notice of the Third  Party  Claim  that the  Indemnifying  Party will
indemnify the Indemnitee as required by (and subject to the limitations of) this
Section 9 for Losses arising out of, relating to, in the nature of, or caused by
the Third Party Claim; (B) the  Indemnifying  Party provides the Indemnitee with
evidence  reasonably  acceptable to the Indemnitee that the  Indemnifying  Party
will have the  financial  resources to defend  against the Third Party Claim and
fulfill its  indemnification  obligations  hereunder;  (C) the Third Party Claim
involves only money  damages and does not seek an injunction or other  equitable
relief;  (D)  settlement  of, or an adverse  judgment with respect to, the Third
Party Claim is not,  in the good faith  judgment  of the  Indemnitee,  likely to
establish a precedential custom or practice materially adverse to the continuing
business interest of the Indemnitee; and (E) the Indemnifying Party conducts the
defense of the Third Party Claim actively and diligently.

             (c) So long as the Indemnifying  Party is conducting the defense of
the  Third  Party  Claim  in  accordance  with  Section  9.8(b)  above,  (A) the
Indemnitee  may retain  separate  co-counsel  at its sole cost and  expense  and
participate in the defense of the Third Party Claim;  (B) the  Indemnitee  shall
not  consent  to the entry of any  judgment  or enter into any  settlement  with
respect  to the Third  Party  Claim  without  the prior  written  consent of the
Indemnifying Party (not to be withheld  unreasonably);  and (C) the Indemnifying
Party  shall  not  consent  to the  entry  of any  judgment  or  enter  into any
settlement  with  respect to the Third  Party Claim  without  the prior  written
consent of the Indemnitee (not to be withheld unreasonably).

             (d) In the event any of the  conditions in Section  9.8(b) above is
or becomes  unsatisfied,  (A) the Indemnitee may defend against,  and consent to
the entry of any  judgment  or enter into any  settlement  with  respect to, the
Third  Party Claim in any manner it  reasonably  may deem  appropriate  (and the
Indemnitee  need not consult with or obtain any consent from,  any  Indemnifying
Party in connection  therewith);  (B) the Indemnifying Party shall reimburse the
Indemnitee  promptly  and  periodically  for the  reasonable  costs of defending
against the Third Party Claim (including attorneys' fees and expenses),  and (C)
the  Indemnifying  Party shall

                                      31.

<PAGE>


remain  responsible  for any Losses the  Indemnitee may suffer  resulting  from,
arising  out of,  relating  to, in the nature  of, or caused by the Third  Party
Claim to the  fullest  extent  provided  in this  Section  9. 

         9.9 Interest.  An  indemnifying  party,  if required to hold  harmless,
indemnify,  compensate  or reimburse any  Indemnitee  pursuant to this Section 9
with  respect  to any  Damages,  shall  also be  liable to such  Indemnitee  for
interest on the amount of such Damages (for the period commencing as of the date
on which the indemnifying party first received notice of a claim for recovery by
such  Indemnitee  and  ending  on  the  date  on  which  the  liability  of  the
indemnifying  party to such  Indemnitee is fully  satisfied by the  indemnifying
party) at a floating  rate equal to the rate of interest  publicly  announced by
Bank of America,  N.T. & S.A. from time to time as its prime,  base or reference
rate.

(without giving effect to principles of conflicts of laws).

based on tort,  contract,  statute,  or for any other cause of action, and which

             (c) Not for the  adjudication  of any matters  (other than judicial

         The parties to this Escrow  Agreement,  intending to be legally  bound,
agree as follows:

of Isonics Stock to be held in escrow in accordance with this Escrow  Agreement,
and deliver such stock  certificates to the Escrow Agent,  and (ii) Seller shall
deliver to the Escrow Agent five "assignments separate from certificate" ("Stock
Powers")  endorsed by Seller in blank,  each signature  guaranteed by a national
bank or New York  Stock  Exchange  member  firm.  The  shares  and Stock  Powers
referred to in this Section 2.1 shall be held by the Escrow Agent in escrow (the
"Escrow") in accordance  with the provisions of this Escrow  Agreement and shall
not be subject to any lien,  attachment,  trustee  process or any other judicial
process of any creditor of any party hereto.

<PAGE>


         2.2  Indemnification.  Seller has agreed in Section 9.2 of the Purchase
Agreement  to  indemnify  and hold  harmless  the  Indemnitees  from and against
Damages.  Seller  agrees  that the  Escrow  Shares  shall be  security  for such
indemnity obligation,  subject to the limitations, and in the manner provided in
this Agreement.

         2.3 Voting of Shares.  The record  owners of the Escrow Shares shall be
entitled to exercise all voting rights with respect to such Escrow Shares.

         2.4   Dividends,   Etc.  Any  cash,   securities   or  other   property
distributable (whether by way of dividend,  stock split or otherwise) in respect
of or in exchange for any Escrow Shares shall not be  distributed  to the record
owner of such Escrow  Shares,  or if  distributed to Seller shall be immediately
delivered  by Seller to the Escrow  Agent,  shall be held by the Escrow Agent in

shall be paid in cash the dollar  amount  (rounded to the nearest  whole  cent),
without  interest,  determined by multiplying  such fraction by $2.26,  and such
fractional share shall be released to Isonics.


SECTION 3.        CLAIM PROCEDURES

         3.1 Claim Notice. If Isonics  determines in good faith that there is or
has been a possible breach by Seller of any representation,  warranty,  covenant
or  other  provision  set  forth  in the  Purchase  Agreement  (collectively,  a
"Breach"), and if Isonics wishes to make a claim against the Escrow with respect
to such possible Breach,  then Isonics may deliver to the Seller's Agent and the
Escrow Agent a written notice of such possible Breach (a "Claim Notice") setting
forth (i) a reasonably  detailed  description  of the  circumstances  supporting
Isonics's  belief that such possible  Breach exists or has occurred,  and (ii) a
non-binding,  preliminary, good faith estimate of the aggregate dollar amount of
all Damages  that have  arisen and may arise as a direct or  indirect  result of
such  possible  Breach (such  aggregate  amount being  referred to as the "Claim
Amount").

         3.2 Response  Notice.  Within 30 calendar  days after the delivery of a
Claim Notice to the Seller's Agent,  the Seller's Agent shall deliver to Isonics
and the Escrow Agent a written notice (the "Response  Notice")  containing:  (i)
instructions  to the effect that Escrow  Shares  having a Fair Market  Value (as
defined in Section 5 of this Escrow  Agreement) equal to the entire Claim Amount
set forth in such Claim Notice are to be released from the Escrow to

<PAGE>


Isonics;  or (ii)  instructions  to the effect that Escrow  Shares having a Fair
Market  Value equal to a specified  portion  (but not the entire  amount) of the
Claim Amount set forth in such Claim  Notice are to be released  from the Escrow
to Isonics,  together with a statement that the remaining  portion of such Claim
Amount is being disputed;  or (iii) a statement that the entire Claim Amount set
forth in such Claim Notice is being disputed.  If no Response Notice is received
by Isonics and the Escrow Agent from the Seller's  Agent within 45 calendar days
after the delivery of a Claim Notice to the Seller's  Agent,  then the recipient
of such Claim  Notice  shall be deemed to have given  instructions  that  Escrow
Shares  having a Fair Market Value equal to the entire Claim Amount set forth in
such Claim Notice are to be released to Isonics from the Escrow.

         3.3      Release of Escrow Shares to Isonics.

                  (a) If the  Seller's  Agent gives (or is deemed to have given)
instructions  to the Escrow Agent that Escrow  Shares having a Fair Market Value
equal to the entire  Claim Amount set forth in a Claim Notice are to be released
from the Escrow to Isonics,  then the Escrow Agent shall be  authorized to use a
Stock Power held in the Escrow to transfer to Isonics,  from the Escrow,  Escrow
Shares having a Fair Market Value equal to such Claim Amount.

                  (b) If a Response  Notice  delivered by the Seller's  Agent in
response  to a Claim  Notice  contains  instructions  to the effect  that Escrow
Shares  having a Fair Market  Value equal to a  specified  portion  (but not the
entire  amount) of the Claim  Amount  set forth in such  Claim  Notice are to be
released  from the  Escrow  to  Isonics,  then  (i) the  Escrow  Agent  shall be
authorized to use a Stock Power held in the Escrow to transfer to Isonics,  from
the Escrow,  Escrow  Shares  having a Fair Market Value equal to such  specified
portion  of such  Claim  Amount,  and (ii) the  procedures  set forth in Section
3.3(c) of this Escrow  Agreement shall be followed with respect to the remaining
portion of such Claim Amount.

                  (c) If a Response  Notice  delivered by the Seller's  Agent in
response to a Claim  Notice  contains a  statement  that all or a portion of the
Claim Amount set forth in such Claim Notice is being disputed (such Claim Amount
or the disputed  portion  thereof being  referred to as the "Disputed  Amount"),
then,  notwithstanding anything contained in Section 4 of this Escrow Agreement,
the Escrow Agent shall  continue to hold in the Escrow (in addition to any other
Escrow Shares permitted to be retained in the Escrow, whether in connection with
any  other  dispute,  pursuant  to  Section  4.1 of this  Escrow  Agreement,  or
otherwise)  Escrow  Shares  having  a Fair  Market  Value  equal  to 100% of the
Disputed  Amount.  Such Escrow  Shares  shall  continue to be held in the Escrow
until such time as (i) Isonics and the Seller's Agent execute and deliver to the
Escrow  Agent a  settlement  agreement  containing  instructions  regarding  the
release of such shares,  or (ii) the Escrow Agent  receives a copy of a court or

duties hereunder.


SECTION 7.        LIMITATION OF ESCROW AGENT'S LIABILITY

         7.1 Limitation.  The Escrow Agent shall incur no liability with respect
to any action  taken or suffered by it in reliance  upon any notice,  direction,

anything  done,  omitted or suffered in good faith by the Escrow  Agent based on
such  advice the Escrow  Agent shall not be liable to anyone.  The Escrow  Agent

good  faith.  The Escrow  Agent  shall have the right to  consult  with  counsel
whenever any question arises  concerning the Escrow Agreement and shall incur no
liability whatsoever, for any delay reasonably required to obtain such advice of
counsel.

         7.4 Other Contract or Agreements. The Escrow Agent is not a party to or
bound by any agreement  between  Isonics,  Seller and Seller's  Agent other than
this The Escrow Agreement,  whether or not an original copy of such agreement is
held by Escrow Agent or is in the files of the Escrow Agent.

         7.5 Validity and Sufficiency of the Escrow. The Escrow Agent assumes no
responsibility  for the validity  and/or  sufficiency of any funds,  securities,
instruments or instructions held as Escrow Shares.


SECTION 8.        SUCCESSOR ESCROW AGENT

         In the event the Escrow  Agent  becomes  unavailable  or  unwilling  to
continue in its capacity herewith, the Escrow Agent may resign and be discharged
from its duties or obligations hereunder by giving resignation to the parties to
this Escrow Agreement,  specifying not less than 60 calendar days' prior written
notice of the date when such resignation shall take effect.  Isonics may appoint
a  successor  Escrow  Agent  without  the  consent  of the Agent so long as such
successor  is a bank with assets of at least $100  million,  and may appoint any
other successor Escrow Agent with the consent of the Agent,  which consent shall
not be unreasonably withheld. If, within such notice period, Isonics provides to
the Escrow  Agent  written  instructions  with respect to the  appointment  of a
successor Escrow Agent and directions for the transfer of any Escrow Shares then
held by the  Escrow  Agent to such  successor,  the  Escrow  Agent  shall act in
accordance with such  instructions  and promptly  transfer such Escrow Shares to
such designated successor.

                  the creditor does not know or suspect to exist in his favor at
                  the time of executing the release,  which if known by him must
                  have materially affected his settlement with the debtor."

Each  Releasor  also hereby waives the benefits of, and any rights such Releasor
may have under,  any statute or common law  principle  of similar  effect in any

unenforceable  in any  jurisdiction,  then (i) such  provision  or part  thereof
shall, with respect to such  circumstances and in such  jurisdiction,  be deemed

including  without  limitation  any  action  or claim  based on tort,  contract,
statute,  or for any other cause of action,  and which relates in any way to the

administered by the American  Arbitration  Association  ("AAA"). The arbitration
shall be  conducted  before a panel of three  arbitrators  under the  commercial
arbitration rules of the AAA and shall be held at an AAA facility in Santa Clara
County,  California.  The parties hereto agree that all  arbitrators  serving on
such  panel  must be  available  to serve on the  panel in  accordance  with the
timetable of the  arbitration.  Not for the  adjudication  of any matters (other
than judicial review for fraud or undisclosed  bias), but for the

                                       4

<PAGE>


enforcement of an arbitration  award or the granting of injunctive  relief,  the
parties hereto irrevocably elect as the sole judicial forum for the adjudication
of any matters arising under or in connection  with this Agreement,  and consent
to the jurisdiction of, the courts of the State of California.

                  (e)  This   General   Release   may  be  executed  in  several
counterparts,  each of which shall constitute an original and all of which, when
taken together,  shall constitute one agreement.  A facsimile copy,  including a

to each Releasee such instruments and other documents, and shall take such other
actions, as such Releasee may reasonably request for the purpose of carrying out
or evidencing any of the actions contemplated by this General Release.

                  (g) If any legal action or other legal proceeding  relating to
this General  Release or the  enforcement of any provision  hereof is brought by
any  Releasor or  Releasee,  the  prevailing  party shall be entitled to recover
reasonable  attorneys'  fees,  costs and  disbursements  to the extent  actually
incurred (in addition to any other relief to which the  prevailing  party may be
entitled).

                  (h) This General  Release shall be effective  with respect to,
and shall be binding upon and  enforceable  against,  each Releasor who executes
this General Release,  regardless of whether any of the other Releasors executes
this General Release.

                  (i)  Whenever  required by the context,  the  singular  number
shall include the plural, and vice versa; the masculine gender shall include the
feminine and neuter  genders;  and the neuter gender shall include the masculine
and feminine genders.

                  (j) Any rule of  construction  to the effect that  ambiguities
are to be  resolved  against  the  drafting  party  shall not be  applied in the
construction or interpretation of this General Release.

                  (k) As used in this General  Release,  the words "include" and

                  (iv) Officer's material breach of the Proprietary  Information

Employer of Officer's  employment  (other than in a Termination  For Cause, or a
termination  by reason of  Officer's  death or  disability)  and shall,  without

Officer of  Officer's  employment  (other  than in a Voluntary  Termination)  by
reason of material  breach of this  Agreement  by  Employer,  which has not been

(10) days after  delivery of such  notice if the breach has not been  cured,  or

Termination) for Good Reason.

             (e) "Change in Control" shall mean any of the following events:

                  (i) as a result  of or in  connection  with  any  cash  tender

                  (ii)  there has  occurred a Change of  Control  and  Officer's
duties and responsibilities  with Employer following such Change of Control have
been   materially   reduced   in  nature   and  scope   from  such   duties  and
responsibilities as they existed immediately before the Change of Control; or

then-present business travel obligations); or

                  (v)  failed to met  annual  financial  support  guidelines  of

"Contact  Period  Expiration  Date") unless the term of this Agreement is sooner
terminated  pursuant to the provisions hereof. The term of employment of Officer
by Employer pursuant to this Agreement shall be renewed  automatically after the
Contract  Period  Expiration  Date for  successive one year renewal terms unless
either party gives notice of non-renewal to the other party not less than thirty
(30)  days  prior to the  expiration  of the then  current  term.  (The  term of
Officer's  employment by Employer  pursuant to this  Agreement will sometimes be
referred to as the "Term").

         2.3 Basic  Consequences of  Termination.  Upon a Termination for Cause,
Termination  Other  Than  For  Cause,   Termination  by  Reason  by  Disability,
Termination  by  Reason  of  Death,  Voluntary   Termination,   or  Constructive
Termination,  all as described in this Section 2, Employer immediately shall pay
to  Officer  all  accrued  salary,  bonus  compensation  to  the  extent  earned
(provided,  however,  that  nothing  in this  Agreement  shall be  construed  as
establishing  any right to any  bonus  compensation  or any pro rata or  accrual
rights to bonus  compensation for partial years of employment),  vested deferred
compensation (other than pension plan or profit sharing plan benefits which will
be paid in accordance with the applicable plan), any benefits under any plans of
Employer  in which  Officer is a  participant  to the full  extent of  Officer's
rights  under such plans,  accrued  vacation  pay and any  appropriate  business
expenses incurred by Officer in connection with Officer's duties hereunder,  all
to the date of termination.  Except for Voluntary Termination or Termination for
Cause,  in addition to payment of the  foregoing  amounts and any  severance  to
which Officer is entitled  hereunder,  the Company shall also immediately pay to

at any time during the term of this Agreement by written notice to Officer. Upon

compensation  or  reimbursement  of  any  kind,  including  without  limitation,
severance compensation.

         2.5 Termination Other Than For Cause.  Notwithstanding anything else in
this  Agreement,  Employer may effect a Termination  Other Than For Cause at any

delivery of written notice to Officer.  Upon  Termination  Other Than For Cause,
Officer shall be entitled to receive the  compensation  described in Section 2.3
above, and all severance compensation provided in Section 4.1 upon a Termination
Other Than For Cause,  but Officer shall not be paid any other  compensation  or
reimbursement of any kind.

                                       3.

<PAGE>


         2.6  Termination  by Reason of  Disability.  If during the term of this
agreement,  Officer,  in the  reasonable  judgment of the Board of  Directors of
Employer  (with  Officer not  participating  in such  decision,  if Officer is a
director of Employer), has failed to perform Officer's essential duties, with or
without reasonable accommodation,  under this Agreement on account of a non-work
related illness or physical or mental incapacity, and such illness or incapacity
continues  for a period of more than six (6)  months,  Employer  shall  have the
right to terminate Officer's  employment  hereunder by written notice to Officer
("Termination  by  Reason  of  Disability").   Upon  Termination  by  Reason  of
Disability,  Officer shall be entitled to receive the compensation  described in
Section  2.3 above,  but no other  compensation  or  reimbursement  of any kind,
including without limitation, severance compensation.

         2.7  Termination  by Reason of Death.  In the event of Officer's  death
during the term of this Agreement,  Officer's employment shall be deemed to have
terminated as of the date on which his death occurred ("Termination by Reason of
Death").  Upon a  Termination  by Reason of Death,  Officer shall be entitled to
receive  the  compensation   described  in  Section  2.3  above,  but  no  other
compensation  or  reimbursement  of  any  kind,  including  without  limitation,
severance compensation.

         2.8  Voluntary  Termination.  Notwithstanding  anything  else  in  this
Agreement,  Officer  may effect a Voluntary  Termination  at any time during the

written  notice to Employer.  In the event of a Voluntary  Termination,  Officer
shall be entitled to receive the  compensation  described  in Section 2.3 above,
but no other  compensation  or  reimbursement  of any  kind,  including  without
limitation, severance compensation.

         2.9  Constructive  Termination.   Officer  may  effect  a  Constructive
Termination at any time during the term of this Agreement,  such  termination to

Officer shall be entitled to receive the  compensation  described in Section 2.3
above,  and  all  severance   compensation   provided  in  Section  4.1  upon  a
Constructive  Termination,  but no other  compensation or  reimbursement  of any
kind.

         2.10 No Severance Compensation Upon Other Termination.  In the event of
a  Voluntary  Termination,  Termination  For  Cause,  Termination  by  Reason of
Disability, or Termination by Reason of Death, Officer or Officer's estate shall
not  be  entitled  by  virtue  of  this   Agreement  to  receive  any  severance
compensation.

         2.11 Parachute  Payments.  If acceleration of the vesting of any option
would (i) constitute a "parachute payment" within the meaning of Section 280G of
the Code and (ii) but for this Section 2.11 be subject to the excise tax imposed
by Section 4999 of the Code (the "Excise Tax"),  then such  acceleration will be
either (A) for all shares subject to this option that are then unvested,  or (B)
such lesser  number of shares as would result in no portion of the  acceleration
being subject to the Excise Tax, whichever of the foregoing amounts, taking into
account the applicable federal, state, and local employment taxes, income taxes,
and the Excise Tax results in Officer's  receipt,  on an after-tax basis, of the
greatest value  notwithstanding that all or some portion of the acceleration may
be  subject to the  Excise  Tax.  The  foregoing

                                       4.

determination  will be made by Employer and Officer jointly,  in good faith, and
will be conclusive and binding upon Employer and Officer.

3.       Salary, Benefits and Bonus Compensation.

         3.1 Base Compensation.  In consideration of the services to be rendered
by Officer to Employer under this Agreement, Employer shall pay Officer a salary
of at least  $100,000  per  year,  payable  monthly  or  otherwise  pursuant  to
Employer's  normal  payroll  procedures.  In years 3 through 5 of this agreement
Employer shall pay office a salary of at least  $125,000.  Employer shall review
annually  Officer's  compensation  in  accordance  with  Employer's  established
administrative   practices  for  adjusting   salaries  for  similarly   situated
employees;  provided,  however,  that nothing in this Section 3 shall impose any
obligation on Employer to increase  Officer's  base  compensation;  and provided
further,  that  Employee's  salary shall not be reduced  during the term of this
Agreement to an amount less than $100,000 per year or $125,000 as appropriate.

         3.2 Benefits.  Officer shall be entitled to a minimum of three weeks of
paid vacation leave per annum.  Officer shall be entitled to three weeks of paid
vacation  per year,  to accrue  monthly,  and to carry  over and  accrue  unused
vacation in any year for use in the  following  year;  provided,  however,  that
Officer shall cease to accrue paid  vacation  leave at any time at which accrued
and unused paid vacation leave equals or exceeds four weeks,  until such time as
accrued and unpaid  vacation  leave no longer  equals or exceeds four weeks.  As
Officer becomes eligible  therefor,  Officer shall have the right to participate
in and receive officer benefits including, without limitation,  health insurance
benefits and life  insurance  benefits  pursuant to the terms of all present and
future benefit plans  specified in Employer's  policies (as such policies may be
amended from time to time) and generally  made  available to similarly  situated
officers of  Employer.  The amount and extent of  benefits  to which  Officer is
entitled shall be governed by the specific  benefit plan, as amended.  Except as
otherwise provided in this Agreement,  nothing contained in this Agreement shall
prevent Employer from changing or eliminating any benefit(s) during the Contract
Period as Employer,  in its sole  discretion,  may deem  necessary or desirable;
provided,  however,  any such  changes or  elimination's  of  benefits  shall be
applicable to all similarly situated  officers.  All compensation and comparable
payments  to be  paid  to  Officer  pursuant  to this  Agreement  shall  be less
withholdings required by law.

         3.3  Incentive  Compensation.  Officer  shall be  eligible  to  receive
incentive  compensation up to 25% of Officer's annual  prevailing  salary in the
year to which such award relates,  as approved from time to time by the Employer
on the terms and  conditions  and subject to the  limitations  of the  Employees
Executive  Compensation  Plan,  as the same may be  amended by  Employer  in its
discretion from time to time.

         3.4  Expenses.   Employer  shall   reimburse   Officer  for  reasonable
out-of-town  travel  and other  business  expenses  incurred  by  Officer in the
performance of Officer's duties, in accordance with Employer's policies, as such
policies may be amended from time to time in Employer's sole discretion.

         4.1  Termination  Other  Than For Cause.  If  Officer's  employment  is
terminated in a Termination  Other Than For Cause,  then Employer shall continue
to pay  Officer  an  amount  equal to his base  salary  under  Section 3 of this
Agreement,  less applicable  withholding taxes,  payable on the Company's normal
payroll dates, in the following amounts:

             (a) If the Termination Other Than For Cause occurs before 18 months
from the Contract Period Expiration Date, then 18 months of base salary;

             (b) If the Termination Other Than For Cause occurs within 18 months
before  expiration  of the Contract  Period  Expiration  Date,  then a number of
months of base salary equal to the remaining  number of months  between the date
of termination and the Contract Period Expiration Date, but no less than six (6)
months of base salary;  and

             (c) If the  Termination  Other  Than For  Cause  occurs  after  the
Contract Period Expiration Date, then six (6) months of base salary.

           If Officer secures other  employment  during the period that payments
  pursuant to this Section 4.1 are payable,  the Company will be entitled to set
  off,  dollar for  dollar,  whatever is earned in such  employment  against the
  amount  owed  to  Officer   hereunder.   During  the  period  that   severance
  compensation is payable  hereunder,  Officer shall notify Employer of any such
  employment and any such other  earnings.  In addition,  Officer shall have the
  option, at Officer's own expense, to extend the health insurance coverage that
  was  provided by  Employer  to Officer as an employee of Employer  immediately
  before the date of termination,  for a period of eighteen (18) months from the
  date of  termination  pursuant to the terms and  conditions of COBRA.  Officer
  shall have sixty (60) days from the date of termination to notify  Employer in
  writing of  Officer's  election  to so  continue  Officer's  health  insurance
  coverage.  Should Officer so elect,  Employer shall reimburse  Officer for the
  cost of the  premiums  under such  health  insurance  plans  under COBRA for a
  period of six (6) months after the termination  date.  After such time,  until
  eighteen (18) months from the date of termination,  Officer may, if Officer so
  elects,  participate  in  Employer's  health  insurance  plans  to the  extent
  permitted  by COBRA and the terms of such  plans,  but any such  participation
  shall be at Officer's sole expense.

         4.2 Termination Obligations.

             (a) Officer  agrees  that all of  Employer's  property  (including,
without limitation, all Employer's equipment, tangible items containing Employer
Proprietary  Information  (as  described  below),  documents,   books,  records,
reports, notes, contracts,  lists, computer disks (and other  computer-generated
files and  data),  and copies  thereof,  created on any  medium)  furnished  to,
obtained  by, or prepared  by Officer in the course of or incident to  Officer's
employment shall be returned  promptly to Employer upon termination of Officer's
employment.

             (b)  The  parties'  respective  representations,   warranties,  and
obligations  contained  in this  Agreement  shall  survive  the  termination  of
Officer's employment.

             (c) Following any termination of the Officer's employment,  Officer
shall  fully  cooperate  with  Employer  in  reasonable  respects in all matters
relating to Officer's continuing obligations under this Agreement.

             (d) A  Termination  for Cause shall not affect or impair the rights
or remedies against Officer.

5. Employer Confidential Information.

         5.1  Definition  of  "Employer  Confidential   Information."  "Employer
Confidential  Information" is all  information,  ideas, and concepts in whatever
form,  tangible  or  intangible,  pertaining  in any manner to the  business  of
Employer,  or any person or entity that  directly  or  indirectly  controls,  is
controlled by, or is under common control with, Employer (an "affiliate") or the
respective officers,  clients,  customers,  suppliers,  consultants, or business
associates of Employer or any affiliate of Employer, which information, idea(s),
or concept(s) have been, or shall have been, produced by any officer or employee
of,  or  consultant  to,  Employer  in the  course of his or her  employment  or
otherwise  produced  or  acquired  by or on  behalf  of  Employer,  that  is not
generally  known outside of Employer's  organization or is so known only through
improper means. Without limiting the foregoing definition, Employer Confidential
Information shall include,  but not be limited to, the following,  to the extent
confidential  or  proprietary  to  Employer:  (i)  confidential  or  proprietary
formulas,   manufacturing   processes,   teaching  and  development  techniques,
processes,  trade secrets,  computer  programs,  electronic  codes,  inventions,
improvements,  and research  projects;  (ii) information  about costs,  profits,
markets, or sales, and lists of vendors, suppliers, customers, or clients; (iii)
business,  marketing,  and strategic plans; and (iv) officer personnel files and
compensation information.

         5.2 General  Restrictions  on Use. While employed by Employer,  Officer
shall use and disclose Employer Confidential Information only for the benefit of
Employer and as is necessary to carry out Officer's  responsibilities under this
Agreement.  Following termination of Officer's employment with Employer, Officer
shall not use or  disclose  any  Employer  Confidential  Information,  except as
expressly authorized in writing by Employer. The restrictions contained above in
this Section 5.2 shall be inapplicable to any Employer Confidential  Information
to the extent that such information: (i) is or becomes publicly known through no
wrongful  act of Officer;  (ii) is  rightfully  received by Officer from a third
party  without  breach of any  obligation  to  Employer;  (iii) is approved  for
release by written  authorization  of Employer;  or (iv) is  distributed or made
available to others by Employer  without  restriction  as to use or  disclosure.
Officer shall have no right or license,  express,  implied or by estoppel, under
any  trademark,  copyright  patent or other  intellectual  property right now or
hereafter owned or controlled by Employer.

         5.3 Third-Party  Information.  Officer  acknowledges  that Employer has
received,  and in the future will  receive,  from third  parties  such  parties'
confidential  information  subject to a duty on Employer's  part to maintain the
confidentiality  of such  information  and to use it only  for  certain  limited
purposes.  Officer  agrees that  Officer owes  Employer and such third  parties,
while employed by Employer and thereafter,  a duty to hold all such confidential
information  in confidence and not to disclose or use it, except as necessary to
perform  Officer's  obligations  hereunder and as is consistent  with Employer's
agreements with such third parties.

waivers, and amendments to this Agreement shall be made and authorized only with
approval of the Board of Directors.

         6.3 Integration.  This Agreement is intended to be the final, complete,
and exclusive statement of the terms of Officer's  employment by Employer.  This
Agreement may not be  contradicted  by evidence of any prior or  contemporaneous
statements  or  agreements.  To the  extent  that the  practices,  policies,  or
procedures  of  Employer,  now  or in the  future,  apply  to  Officer  and  are
inconsistent with the terms of this Agreement,  the provisions of this Agreement
shall control.

         6.4 Amendments;  Waivers. This Agreement may not be modified,  amended,
or terminated except by an instrument in writing signed by Officer and signed by
an officer of Employer  specifically  authorized  by the Board of  Directors  to
execute such instrument. No failure to exercise, and no delay in exercising, any
right,  remedy, or power under this Agreement shall operate as a waiver thereof,
and no single or partial  exercise  of any right,  remedy,  or power  under this
Agreement shall preclude any other or further  exercise  thereof or the exercise
of any other right, remedy, or power provided herein or at law or in equity.

         6.5  Assignment;  Successors  and Assigns.  Officer agrees that Officer
will not assign,  sell,  transfer,  delegate,  or otherwise  dispose of, whether
voluntarily or involuntarily,  or by operation of law, any rights or obligations
under this Agreement.  Any such purported  assignment,  transfer,  or delegation
shall  be  null  and  void.   Nothing  in  this  Agreement   shall  prevent  the
consolidation  of Employer  with, or its merger into,  any other entity,  or the
sale by Employer of all or substantially all of its assets, or the assignment by
Employer of any rights or obligations under this Agreement;  provided,  however,
no  assignment by Employer  shall release or discharge  Employer from any of its
obligations under this Agreement. Subject to the foregoing, this Agreement shall
be  binding  upon and  shall  inure to the  benefit  of the  parties  and  their
respective heirs, legal representatives,  successors,  and permitted assigns and
shall not benefit any person or entity other than those specifically  enumerated
in this Agreement.

         6.6  Severability.   If  any  provision  of  this  Agreement,   or  its
application  to any  person,  place,  or  circumstance,  is held  by a court  of
competent  jurisdiction  to be invalid,  unenforceable,  or void, such provision
shall be enforced to the greatest  extent  permitted by law and the remainder of
this  Agreement  and such  provision as applied to other  persons,  places,  and
circumstances shall remain in full force and effect.

         6.7  Attorneys'  Fees.  In any legal action,  or proceeding  brought to
enforce the terms of this Agreement,  the prevailing  party in such legal action
or proceeding  shall be entitled to recover its reasonable  attorneys'  fees and
costs from the other party.

         6.8 Injunctive  Relief. If either party breaches or threatens to breach
any of his or its  respective  obligations  under  Sections  4.2  and 5 of  this
Agreement,  the parties  acknowledge that the damage or imminent damage would be
irreparable and extremely difficult to estimate, making any remedy at law or for
damages inadequate. Accordingly, in such circumstances a party shall be entitled
to injunctive  relief against the other party in the event of any such breach or
threatened breach in addition to any other relief (including  damages) available
under this Agreement or at law.

                                       9.

         6.9 Governing Law; Arbitration.

             (a) This  Agreement  shall be construed  in  accordance  with,  and
governed  in all  respects  by,  the  internal  laws of the State of  California
(without giving effect to principles of conflicts of laws).

             (b) Any dispute,  claim or controversy of any nature arising out of
or relating to this Agreement,  including without limitation any action or claim
based on tort,  contract,  statute,  or for any other cause of action, and which
relates  in any  way  to  the  interpretation,  effect,  termination,  validity,
enforcement,  performance and/or breach of this Agreement,  shall be resolved by
final binding arbitration  administered by the American Arbitration  Association
("AAA").  The arbitration shall be conducted before a panel of three arbitrators
under the  commercial  arbitration  rules of the AAA and shall be held at an AAA
facility in the City and County of Denver,  Colorado.  The parties  hereto agree
that all  arbitrators  serving on such panel must be  available  to serve on the
panel in  accordance  with the  timetable  of the  arbitration.

             (c) Not for the  adjudication  of any matters  (other than judicial
review for fraud or undisclosed bias), but for the enforcement of an arbitration
award or the granting of injunctive relief, the parties hereto irrevocably elect
as the sole judicial forum for the  adjudication of any matters arising under or
in  connection  with this  Agreement,  and consent to the  jurisdiction  of, the
courts of the State of Colorado.

         6.10 Counterparts; Facsimile Signatures. This Agreement may be executed
in one or more counterparts, each of which shall constitute an original, but all
of which taken together shall constitute one and the same Agreement. A facsimile
copy,  including a facsimile copy of a signature,  shall have the same force and
effect as an original.

         6.11 Officer Acknowledgment.  Officer acknowledges that Officer has had
the  opportunity to consult legal counsel with respect to this  agreement,  that
Officer has read and understands this Agreement,  that Officer is fully aware of
its legal effect,  and that Officer has entered into this  Agreement  freely and
voluntarily  and based on Officer's own judgment and not on any  representations
or promises other than those contained in this Agreement.

                      INTERPRO FINANCIAL SUPPORT GUIDELINES

In each year during the term of the Employment Agreement in which Interpro meets
its revenue and  earnings  growth  projections  of 20 percent per year,  Isonics
agrees, at its election,  to either (a) advance funds up to $200,000 per year as
requested by Interpro or (b) guarantee  bank or other loans  designed to provide
the needed working  capital to Interpro.  If the revenue and earnings  growth is
less than 20 percent per year,  Isonics  has the option to reduce  such  funding
proportionately, i.e., if revenue growth is 15 percent and earnings growth is 10
percent  then  advances or  guarantees  are reduced to  $100,000,  or if revenue
growth  is 10  percent  and  earnings  growth is 15  percent  then  advances  or
guarantees  are  reduced  to  $100,000.  In any  event,  Isonics  agrees to fund
Interpro with no less than $50,000 per year of working capital  annually,  for a
period of five years,  assuming  Interpro has positive  earnings  before  income
taxes, depreciation and amortization.

                            NONCOMPETITION AGREEMENT


         This NONCOMPETITION AGREEMENT is being executed and delivered as of May

         B. Pursuant to a Stock  Purchase  Agreement  dated as of April 30, 1998
among the  Purchaser,  MII and the Company (the  "Purchase  Agreement"),  MII is

Agreement  and  the  transactions  contemplated  thereby,  and as  the  majority
shareholder of MII is a beneficiary thereof.

         C. In connection  with the  acquisition  by the Purchaser of all of the
outstanding  stock of the Company  pursuant to the Purchase  Agreement (and as a
condition to the consummation of such acquisition),  and to enable the Purchaser
to secure  more  fully the  benefits  of such  acquisition,  the  Purchaser  has
required that the Stockholder enter into this Noncompetition  Agreement; and the
Stockholder  is entering into this  Noncompetition  Agreement in order to induce
the  Purchaser  to  consummate  the  acquisition  contemplated  by the  Purchase
Agreement.

         D. The  Purchaser  and the  Stockholder  are  executing  an  Employment
Agreement (the "Employment Agreement")  contemporaneously with the execution and
delivery of this Noncompetition Agreement. Pursuant to the Employment Agreement,
the Stockholder is becoming a key employee of the Purchaser and will accordingly
obtain extensive and valuable knowledge and confidential  information concerning
the  businesses  of  the  Purchaser,  the  Company  and  the  Purchaser's  other
subsidiaries.

         E. The Purchaser,  the Company and the Purchaser's  other  subsidiaries
have  conducted and are  conducting  their  respective  businesses on a national
basis.

         Person  that  engages  directly or  indirectly  in  Competition  in any
         Restricted Territory;

provided,  however,  that the Stockholder may, without violating this Section 1,
own,  as a  passive  investment,  shares  of  capital  stock of a  publicly-held
corporation  that engages in Competition if (i) such shares are actively  traded
on an established  national  securities  market in the United  States,  (ii) the
number of shares of such corporation's capital stock that are owned beneficially
(directly or  indirectly)  by the  Stockholder  and the number of shares of such
corporation's capital stock that are owned beneficially (directly or indirectly)
by the Stockholder's  Affiliates collectively represent less than one percent of
the total number of shares of such corporation's capital stock outstanding,  and
(iii) neither the  Stockholder nor any Affiliate of the Stockholder is otherwise
associated directly or indirectly with such corporation or with any Affiliate of

Purchaser, the Company or any of the Purchaser's other subsidiaries to leave his
or her  employment  with the  Purchaser,  the Company or any of the  Purchaser's

this  Noncompetition  Agreement,  and (ii) remains or becomes an employee of the
Purchaser,  the Company or any of the Purchaser's other subsidiaries on the date
of this  Noncompetition  Agreement  or at any  time  during  the  Noncompetition
Period.)

         3.  Confidentiality.  The  Stockholder  agrees  that he shall  hold all
Confidential Information in strict confidence and shall not at any time (whether
during  or after  the  Noncompetition  Period):  (a)  reveal,  report,  publish,
disclose or transfer any Confidential  Information to any Person (other than the
Purchaser or the Company),  except in the performance of his  obligations  under
the Employment Agreement;  (b) use any Confidential Information for

                                       2

any purpose,  except in the performance of his obligations  under the Employment
Agreement; or (c) use any Confidential Information for the benefit of any Person
(other than the Purchaser or the Company).

         4.  Representations  and  Warranties.  The  Stockholder  represents and
warrants, to and for the benefit of the Indemnitees, that: (a) he has full power
and  capacity to execute  and  deliver,  and to perform  all of his  obligations
under,  this  Noncompetition  Agreement;  and (b) to the  best of his  knowledge
neither the  execution  and delivery of this  Noncompetition  Agreement  nor the
performance of this Noncompetition  Agreement will result directly or indirectly
in a  violation  or  breach  of (i) any  agreement  or  obligation  by which the
Stockholder or any of his  Affiliates is or may be bound,  or (ii) any law, rule
or regulation.  The Stockholder's  representations  and warranties shall survive
the expiration of the Noncompetition Period for a period of one year.

         5. Specific  Performance.  The Stockholder agrees that, in the event of
any breach or threatened breach by the Stockholder of any covenant or obligation
contained in this Noncompetition  Agreement,  each of the Purchaser, the Company
and the other  Indemnitees  shall be entitled  (in  addition to any other remedy
that may be available to it, including  monetary damages) to seek and obtain (a)
a decree  or  order of  specific  performance  to  enforce  the  observance  and
performance  of such covenant or obligation,  and (b) an injunction  restraining
such  breach or  threatened  breach.  The  Stockholder  further  agrees  that no
Indemnitee  shall be  required  to  obtain,  furnish or post any bond or similar
instrument in connection with or as a condition to obtaining any remedy referred
to in this Section 5, and the  Stockholder  irrevocably  waives any right he may
have to  require  any  Indemnitee  to  obtain,  furnish or post any such bond or
similarly instrument.

         6.  Indemnification.  Without in any way  limiting any of the rights or
remedies  otherwise  available to any of the Indemnitees,  the Stockholder shall
indemnify and hold harmless each Indemnitee  against and from any loss,  damage,
injury, harm, detriment, lost opportunity,  liability,  exposure, claim, demand,
settlement,  judgment,  award,  fine,  penalty,  tax, fee (including  reasonable
attorneys' fees),  charge or expense  (including  third-party claims relating to
this  Noncompetition  Agreement)  that is  directly  or  indirectly  suffered or
incurred at any time (whether during or after the Noncompetition Period) by such
Indemnitee,  or to which such Indemnitee  otherwise becomes subject at any time,
and that  arises  directly  or  indirectly  out of or by virtue  of, or  relates
directly or indirectly to, (a) any inaccuracy in or breach of any representation
or warranty contained in this  Noncompetition  Agreement,  or (b) any failure on
the part of the Stockholder to observe, perform or abide by, or any other breach
of, any restriction,  covenant,  obligation or other provision contained in this
Noncompetition Agreement.

         7.  Non-Exclusivity.  The rights and  remedies  of the  Purchaser,  the
Company and the other  Indemnitees under this  Noncompetition  Agreement are not
exclusive  of or limited by any other  rights or  remedies  which they may have,
whether at law,  in equity,  by  contract  or  otherwise,  all of which shall be
cumulative  (and  not  alternative).  Without  limiting  the  generality  of the
foregoing,  the rights and remedies of the Purchaser,  the Company and the other
Indemnitees  under  this  Noncompetition  Agreement,  and  the  obligations  and
liabilities  of the  Stockholder  under this  Noncompetition  Agreement,  are in
addition to their respective rights, remedies, obligations and liabilities under
the law of unfair competition,  under laws relating to

                                        3

<PAGE>


misappropriation of trade secrets,  under other laws and common law requirements
and under all applicable rules and regulations.  Nothing in this  Noncompetition
Agreement  shall limit any of the  Stockholder's  obligations,  or the rights or
remedies of the Purchaser,  the Company or any of the other  Indemnitees,  under
the Purchase Agreement or the Employment Agreement;  and nothing in the Purchase
Agreement  or the  Employment  Agreement  shall  limit any of the  Stockholder's
obligations,  or any of the rights or remedies of the Purchaser, the Company, or
any of the other Indemnitees,  under this Noncompetition Agreement. No breach on
the part of the  Purchaser,  the Company or any other  party of any  covenant or
obligation contained in the Purchase Agreement,  the Employment Agreement or any
other  agreement  shall  limit or  otherwise  affect  any right or remedy of the
Purchaser,   the   Company  or  any  of  the  other   Indeminitees   under  this
Noncompetition Agreement.

         8. Severability.  If any provision of this Noncompetition  Agreement or
any part of any such provision is held under any  circumstances to be invalid or
unenforceable  in any  jurisdiction,  then (a) such  provision  or part  thereof
shall, with respect to such  circumstances and in such  jurisdiction,  be deemed
amended to conform to applicable  laws so as to be valid and  enforceable to the
fullest  possible  extent,  (b)  the  invalidity  or  unenforceability  of  such
provision  or part thereof  under such  circumstances  and in such  jurisdiction
shall not  affect the  validity  or  enforceability  of such  provision  or part
thereof under any other circumstances or in any other jurisdiction,  and (c) the
invalidity  or  unenforceability  of such  provision or part  thereof  shall not
affect the validity or  enforceability of the remainder of such provision or the
validity  or  enforceability  of any  other  provision  of  this  Noncompetition
Agreement.  Each  provision of this  Noncompetition  Agreement is separable from
every other provision of this  Noncompetition  Agreement,  and each part of each
provision of this Noncompetition Agreement is separable from every other part of
such provision.

          9.      Governing Law; Arbitration.

                  (a) This Agreement shall be construed in accordance  with, and
governed  in all  respects  by,  the  internal  laws of the State of  California
(without giving effect to principles of conflicts of laws).

                  (b) Any dispute,  claim or  controversy  of any nature arising
out of or relating to this Agreement, including without limitation any action or
claim based on tort,  contract,  statute,  or for any other cause of action, and
which relates in any way to the interpretation,  effect, termination,  validity,
enforcement,  performance and/or breach of this Agreement,  shall be resolved by
final binding arbitration  administered by the American Arbitration  Association
("AAA").  The arbitration shall be conducted before a panel of three arbitrators
under the  commercial  arbitration  rules of the AAA and shall be held at an AAA
facility in the City and County of Denver,  Colorado.  The parties  hereto agree
that all  arbitrators  serving on such panel must be  available  to serve on the
panel in accordance with the timetable of the arbitration.

                  (c)  Not for  the  adjudication  of any  matters  (other  than
judicial  review for fraud or undisclosed  bias),  but for the enforcement of an
arbitration  award or the  granting of  injunctive  relief,  the parties  hereto
irrevocably elect as the sole judicial forum for the adjudication of any matters
arising  under  or in  connection  with  this  Agreement,  and  consent  to  the
jurisdiction of, the courts of the State of Colorado.

                                       4

         10. Waiver. No failure on the part of the Purchaser, the Company or any
other  Indemnitee to exercise any power,  right,  privilege or remedy under this
Noncompetition Agreement, and no delay on the part of the Purchaser, the Company
or any other  Indemnitee in  exercising  any power,  right,  privilege or remedy
under this  Noncompetition  Agreement,  shall operate as a waiver of such power,
right, privilege or remedy; and no single or partial exercise of any such power,
right,  privilege or remedy shall preclude any other or further exercise thereof
or of any other power, right, privilege or remedy. No Indemnitee shall be deemed
to have waived any claim of such Indemnitee  arising out of this  Noncompetition
Agreement,  or any power,  right,  privilege or remedy of such Indemnitee  under
this  Noncompetition  Agreement,  unless the waiver of such claim, power, right,
privilege or remedy is expressly set forth in a written instrument duly executed
and  delivered  on behalf of such  Indemnitee;  and any such waiver shall not be
applicable  or have any effect  except in the  specific  instance in which it is
given.

         11. Successors and Assigns. Each of the Purchaser,  the Company and the
other  Indemnitees  may  freely  assign  any or all of  its  rights  under  this
Noncompetition  Agreement,  at any  time,  in whole or in  part,  to any  Person
without  obtaining  the consent or approval of the  Stockholder  or of any other
Person. This Noncompetition  Agreement shall be binding upon the Stockholder and
his heirs, executors, estate, personal representatives,  successors and assigns,
and shall  inure to the  benefit of the  Purchaser,  the  Company  and the other
Indemnitees.

         12. Further  Assurances.  The Stockholder  shall (at the  Stockholder's
sole  expense)  execute  and/or cause to be delivered  to each  Indemnitee  such
instruments and other documents,  and shall (at the Stockholder's  sole expense)
take such other actions,  as such Indemnitee may reasonably  request at any time
(whether during or after the Noncompetition  Period) for the purpose of carrying
out or evidencing any of the provisions of this Noncompetition Agreement.

         13.  Attorneys'  Fees.  If any legal  action or other legal  proceeding
relating to this Noncompetition Agreement or the enforcement of any provision of
this Noncompetition Agreement is brought against the Stockholder, the prevailing
party  shall be  entitled  to  recover  reasonable  attorneys'  fees,  costs and
disbursements (in addition to any other relief to which the prevailing party may
be entitled).

         14. Captions.  The captions contained in this Noncompetition  Agreement

shall include the plural, and vice versa; the masculine gender shall include the
feminine and neuter  genders;  and the neuter gender shall include the masculine

the  obligations  of  the  Stockholder  under  this   Noncompetition   Agreement
(including  his  obligations  under  Sections  3, 6 and 12)  shall  survive  the
expiration of the  Noncompetition  Period.  The expiration of the Noncompetition

this Noncompetition Agreement.

         17.  Obligations  Absolute.  The  Stockholder's  obligations under this

of any obligation of the  Purchaser,  the Company,  any other  Indemnitee or any

Releasor or any of such Releasor's Associated Parties.


         6.       Miscellaneous.

                  (a) This General  Release sets forth the entire  understanding
of the parties  relating to the subject  matter hereof and  supersedes all prior
agreements  and  understandings  among  or  between  any  of the  Releasors  and
Releasees relating to the subject matter hereof.

                  (b) If any  provision of this  General  Release or any part of
any  such  provision  is  held  under  any   circumstances   to  be  invalid  or
unenforceable  in any  jurisdiction,  then (i) such  provision  or part  thereof
shall, with respect to such  circumstances and in such  jurisdiction,  be deemed
amended to conform to applicable  laws so as to be valid and  enforceable to the
fullest  possible  extent,  (ii)  the  invalidity  or  unenforceability  of such
provision  or part thereof  under such  circumstances  and in such  jurisdiction
shall not  affect the  validity  or  enforceability  of such  provision  or part
thereof under any other  circumstances or in any other  jurisdiction,  and (iii)
such  invalidity or  enforceability  of such provision or part thereof shall not
affect the validity or  enforceability of the remainder of such provision or the
validity or  enforceability  of any other provision of this General Release.  If
any provision of this General  Release or any part of such  provision is held to
be  unenforceable  against  any  Releasor,  then  the  unenforceability  of such
provision  or  part  thereof   against  such  Releasor   shall  not  affect  the
enforceability  thereof  against  any other  Releasor.  Each  provision  of this
General Release is separable from every other provision of this General Release,
and each part of each provision of this General  Release is separable from every
other part of such provision.

                  (c) This General  Release  shall be  construed  in  accordance
with,  and  governed  in all  respects  by, the laws of the State of  California
(without giving effect to principles of conflicts of laws).  Any dispute,  claim
or  controversy  of any nature  arising out of or  relating  to this  Agreement,
including  without  limitation  any  action  or claim  based on tort,  contract,
statute,  or for any other cause of action,  and which relates in any way to the
interpretation,  effect, termination, validity, enforcement,  performance and/or
breach  of this  Agreement,  shall  be  resolved  by final  binding  arbitration
administered by the American  Arbitration  Association  ("AAA"). The arbitration
shall be  conducted  before a panel of three  arbitrators  under the  commercial
arbitration rules of the AAA and shall be held at an AAA facility in Santa Clara
County,  California.  The parties hereto agree that all  arbitrators  serving on
such  panel  must be  available  to serve on the  panel in  accordance  with the
timetable of the  arbitration.  Not for the  adjudication  of any matters (other
than judicial review for fraud or undisclosed  bias), but for the

                                       4

<PAGE>


enforcement of an arbitration  award or the granting of injunctive  relief,  the
parties hereto irrevocably elect as the sole judicial forum for the adjudication
of any matters arising under or in connection  with this Agreement,  and consent
to the jurisdiction of, the courts of the State of California.

                  (e)  This   General   Release   may  be  executed  in  several
counterparts,  each of which shall constitute an original and all of which, when
taken together,  shall constitute one agreement.  A facsimile copy,  including a
facsimile  copy of a  signature,  shall  have the same  force  and  effect as an
original.

                  (f) Each Releasor  shall execute  and/or cause to be delivered
to each Releasee such instruments and other documents, and shall take such other
actions, as such Releasee may reasonably request for the purpose of carrying out
or evidencing any of the actions contemplated by this General Release.

                  (g) If any legal action or other legal proceeding  relating to
this General  Release or the  enforcement of any provision  hereof is brought by
any  Releasor or  Releasee,  the  prevailing  party shall be entitled to recover
reasonable  attorneys'  fees,  costs and  disbursements  to the extent  actually
incurred (in addition to any other relief to which the  prevailing  party may be
entitled).

                  (h) This General  Release shall be effective  with respect to,
and shall be binding upon and  enforceable  against,  each Releasor who executes
this General Release,  regardless of whether any of the other Releasors executes
this General Release.

                  (i)  Whenever  required by the context,  the  singular  number
shall include the plural, and vice versa; the masculine gender shall include the
feminine and neuter  genders;  and the neuter gender shall include the masculine
and feminine genders.

                  (j) Any rule of  construction  to the effect that  ambiguities
are to be  resolved  against  the  drafting  party  shall not be  applied in the
construction or interpretation of this General Release.

                  (k) As used in this General  Release,  the words "include" and
"including,"  and  variations  thereof,  shall  not be  deemed  to be  terms  of
limitation,   and  shall  be  deemed  to  be  followed  by  the  words  "without
limitation."

of which are held  beneficially and of record by Seller,  in exchange for shares

         B. The Purchase  Agreement  contemplates the establishment of an escrow
arrangement to secure the  indemnification and other obligations of Seller under
the Purchase Agreement.

                                    AGREEMENT

         The parties to this Escrow  Agreement,  intending to be legally  bound,
agree as follows:


SECTION 1.        DEFINED TERMS

         Capitalized  terms  used  and not  otherwise  defined  in  this  Escrow
Agreement shall have the meanings assigned to them in the Purchase Agreement.


SECTION 2.        ESCROW

         2.1 Shares  and Stock  Powers to be Placed in  Escrow.  On the  Closing
Date, (i) Isonics shall issue certificates for an aggregate of 176,991 shares of
Isonics Stock (the "Escrow Shares") in the name of Seller, evidencing the shares
of Isonics Stock to be held in escrow in accordance with this Escrow  Agreement,
and deliver such stock  certificates to the Escrow Agent,  and (ii) Seller shall
deliver to the Escrow Agent five "assignments separate from certificate" ("Stock
Powers")  endorsed by Seller in blank,  each signature  guaranteed by a national
bank or New York  Stock  Exchange  member  firm.  The  shares  and Stock  Powers
referred to in this Section 2.1 shall be held by the Escrow Agent in escrow (the
"Escrow") in accordance  with the provisions of this Escrow  Agreement and shall
not be subject to any lien,  attachment,  trustee  process or any other judicial
process of any creditor of any party hereto.



<PAGE>


         2.2  Indemnification.  Seller has agreed in Section 9.2 of the Purchase
Agreement  to  indemnify  and hold  harmless  the  Indemnitees  from and against
Damages.  Seller  agrees  that the  Escrow  Shares  shall be  security  for such
indemnity obligation,  subject to the limitations, and in the manner provided in
this Agreement.

         2.3 Voting of Shares.  The record  owners of the Escrow Shares shall be
entitled to exercise all voting rights with respect to such Escrow Shares.

         2.4   Dividends,   Etc.  Any  cash,   securities   or  other   property
distributable (whether by way of dividend,  stock split or otherwise) in respect
of or in exchange for any Escrow Shares shall not be  distributed  to the record
owner of such Escrow  Shares,  or if  distributed to Seller shall be immediately
delivered  by Seller to the Escrow  Agent,  shall be held by the Escrow Agent in
the Escrow.  At the time any Escrow  Shares are required to be released from the
Escrow to any Person pursuant to this Escrow Agreement,  any cash, securities or
other  property  previously  distributed  in respect of or in exchange  for such
Escrow Shares shall be released from the Escrow to such Person.

         2.5  Transferability.  The interests of Seller in the Escrow and in the

retained in or released from the Escrow  pursuant to this Escrow  Agreement.  In
connection  with any release of Escrow  Shares from the  Escrow,  Seller,  which
would  otherwise  be entitled to receive a fraction of a share of Isonics  Stock
(after  aggregating  all fractional  shares of Isonics Stock issuable to Seller)
shall be paid in cash the dollar  amount  (rounded to the nearest  whole  cent),
without  interest,  determined by multiplying  such fraction by $2.26,  and such
fractional share shall be released to Isonics.


SECTION 3.        CLAIM PROCEDURES

         3.1 Claim Notice. If Isonics  determines in good faith that there is or
has been a possible breach by Seller of any representation,  warranty,  covenant
or  other  provision  set  forth  in the  Purchase  Agreement  (collectively,  a
"Breach"), and if Isonics wishes to make a claim against the Escrow with respect
to such possible Breach,  then Isonics may deliver to the Seller's Agent and the
Escrow Agent a written notice of such possible Breach (a "Claim Notice") setting
forth (i) a reasonably  detailed  description  of the  circumstances  supporting
Isonics's  belief that such possible  Breach exists or has occurred,  and (ii) a
non-binding,  preliminary, good faith estimate of the aggregate dollar amount of
all Damages  that have  arisen and may arise as a direct or  indirect  result of
such  possible  Breach (such  aggregate  amount being  referred to as the "Claim
Amount").

         3.2 Response  Notice.  Within 30 calendar  days after the delivery of a
Claim Notice to the Seller's Agent,  the Seller's Agent shall deliver to Isonics
and the Escrow Agent a written notice (the "Response  Notice")  containing:  (i)
instructions  to the effect that Escrow  Shares  having a Fair Market  Value (as
defined in Section 5 of this Escrow  Agreement) equal to the entire Claim Amount
set forth in such Claim Notice are to be released from the Escrow to

                                       2

<PAGE>


Isonics;  or (ii)  instructions  to the effect that Escrow  Shares having a Fair
Market  Value equal to a specified  portion  (but not the entire  amount) of the
Claim Amount set forth in such Claim  Notice are to be released  from the Escrow
to Isonics,  together with a statement that the remaining  portion of such Claim
Amount is being disputed;  or (iii) a statement that the entire Claim Amount set
forth in such Claim Notice is being disputed.  If no Response Notice is received
by Isonics and the Escrow Agent from the Seller's  Agent within 45 calendar days
after the delivery of a Claim Notice to the Seller's  Agent,  then the recipient
of such Claim  Notice  shall be deemed to have given  instructions  that  Escrow
Shares  having a Fair Market Value equal to the entire Claim Amount set forth in
such Claim Notice are to be released to Isonics from the Escrow.

         3.3      Release of Escrow Shares to Isonics.

                  (a) If the  Seller's  Agent gives (or is deemed to have given)
instructions  to the Escrow Agent that Escrow  Shares having a Fair Market Value
equal to the entire  Claim Amount set forth in a Claim Notice are to be released
from the Escrow to Isonics,  then the Escrow Agent shall be  authorized to use a
Stock Power held in the Escrow to transfer to Isonics,  from the Escrow,  Escrow
Shares having a Fair Market Value equal to such Claim Amount.

                  (b) If a Response  Notice  delivered by the Seller's  Agent in
response  to a Claim  Notice  contains  instructions  to the effect  that Escrow
Shares  having a Fair Market  Value equal to a  specified  portion  (but not the
entire  amount) of the Claim  Amount  set forth in such  Claim  Notice are to be
released  from the  Escrow  to  Isonics,  then  (i) the  Escrow  Agent  shall be
authorized to use a Stock Power held in the Escrow to transfer to Isonics,  from
the Escrow,  Escrow  Shares  having a Fair Market Value equal to such  specified
portion  of such  Claim  Amount,  and (ii) the  procedures  set forth in Section
3.3(c) of this Escrow  Agreement shall be followed with respect to the remaining
portion of such Claim Amount.

                  (c) If a Response  Notice  delivered by the Seller's  Agent in
response to a Claim  Notice  contains a  statement  that all or a portion of the
Claim Amount set forth in such Claim Notice is being disputed (such Claim Amount
or the disputed  portion  thereof being  referred to as the "Disputed  Amount"),
then,  notwithstanding anything contained in Section 4 of this Escrow Agreement,
the Escrow Agent shall  continue to hold in the Escrow (in addition to any other
Escrow Shares permitted to be retained in the Escrow, whether in connection with
any  other  dispute,  pursuant  to  Section  4.1 of this  Escrow  Agreement,  or
otherwise)  Escrow  Shares  having  a Fair  Market  Value  equal  to 100% of the
Disputed  Amount.  Such Escrow  Shares  shall  continue to be held in the Escrow
until such time as (i) Isonics and the Seller's Agent execute and deliver to the
Escrow  Agent a  settlement  agreement  containing  instructions  regarding  the
release of such shares,  or (ii) the Escrow Agent  receives a copy of a court or
arbitration  final order  containing  instructions to the Escrow Agent regarding
the release of such Escrow  Shares,  and Escrow  Agent shall be entitled to rely
conclusively on such final order. The Escrow Agent shall thereupon  release such
Escrow Shares from the Escrow in accordance with the  instructions  set forth in
such settlement agreement or court or arbitration order.

Seller's  Agent and the Escrow Agent in connection  with the  performance of his
duties hereunder.


SECTION 7.        LIMITATION OF ESCROW AGENT'S LIABILITY

         7.1 Limitation.  The Escrow Agent shall incur no liability with respect
to any action  taken or suffered by it in reliance  upon any notice,  direction,
instruction,  consent, statement or other documents believed by it to be genuine
and duly  authorized,  nor for other  action or inaction  except its own willful
misconduct  or  negligence.  The Escrow Agent shall not be  responsible  for the
validity or sufficiency of this  Agreement.  In all questions  arising under the
Escrow  Agreement,  the Escrow Agent may rely on the advice of counsel,  and for
anything  done,  omitted or suffered in good faith by the Escrow  Agent based on
such  advice the Escrow  Agent shall not be liable to anyone.  The Escrow  Agent
shall not be required to take any action hereunder  involving any expense unless
the  payment of such  expense  is made or  provided  for in a manner  reasonably
satisfactory to it.

         7.2  Indemnification of Escrow Agent.  Isonics and Seller,  jointly and
severally,  shall indemnify the Escrow Agent for, and hold it harmless  against,
any loss, liability or expense incurred without negligence or willful misconduct
on the part of Escrow Agent,  arising out of or in connection  with its carrying
out of its duties hereunder,  including any extraordinary fees and expenses that
may arise, such as fees of counsel and court costs. As among themselves, each of
Isonics  and Seller  shall be liable for  one-half  (1/2) of such  amounts.  The
Escrow Agent has a first and prior lien on the Escrow  Shares to secure any such
fees and  expenses.  The Escrow

                                       4

<PAGE>


Agent is authorized to deduct any such fees and expenses from the Escrow Shares.
Any fees and expenses  owed but unpaid shall secure  interest at the rate of 12%
per annum.

         7.3 Non-Liability.  The Escrow Agent shall not be liable for any act it
may do or omit to do as the Escrow  Agent while  acting in good faith and in the
exercise of its own best  judgment.  Any act done or omitted by the Escrow Agent
pursuant to the advice of its  attorneys  shall be  conclusive  evidence of such
good  faith.  The Escrow  Agent  shall have the right to  consult  with  counsel
whenever any question arises  concerning the Escrow Agreement and shall incur no
liability whatsoever, for any delay reasonably required to obtain such advice of
counsel.

         7.4 Other Contract or Agreements. The Escrow Agent is not a party to or
bound by any agreement  between  Isonics,  Seller and Seller's  Agent other than
this The Escrow Agreement,  whether or not an original copy of such agreement is
held by Escrow Agent or is in the files of the Escrow Agent.

         7.5 Validity and Sufficiency of the Escrow. The Escrow Agent assumes no
responsibility  for the validity  and/or  sufficiency of any funds,  securities,
instruments or instructions held as Escrow Shares.


SECTION 8.        SUCCESSOR ESCROW AGENT

         In the event the Escrow  Agent  becomes  unavailable  or  unwilling  to
continue in its capacity herewith, the Escrow Agent may resign and be discharged
from its duties or obligations hereunder by giving resignation to the parties to
this Escrow Agreement,  specifying not less than 60 calendar days' prior written
notice of the date when such resignation shall take effect.  Isonics may appoint
a  successor  Escrow  Agent  without  the  consent  of the Agent so long as such
successor  is a bank with assets of at least $100  million,  and may appoint any
other successor Escrow Agent with the consent of the Agent,  which consent shall
not be unreasonably withheld. If, within such notice period, Isonics provides to
the Escrow  Agent  written  instructions  with respect to the  appointment  of a
successor Escrow Agent and directions for the transfer of any Escrow Shares then
held by the  Escrow  Agent to such  successor,  the  Escrow  Agent  shall act in
accordance with such  instructions  and promptly  transfer such Escrow Shares to
such designated successor.


SECTION 9.        GENERAL

         9.1  Confirmation of  Appointment.  Seller confirms the appointment and
authority  of the  Seller's  Agent as set  forth  in  Section  10.1 of  Purchase
Agreement  with respect to all matters  relating to this Escrow  Agreement.  Any
successor  to the  Seller's  Agent  who is  appointed  in  accordance  with  the
provisions of Section 10.1 of the Purchase  Agreement  shall be deemed to be the
"Seller's Agent" for purposes of this Escrow Agreement. Any document executed or
action taken by the Seller's Agent shall be binding upon Seller.

         9.2 Other  Agreements.  Nothing in this Escrow Agreement is intended to
limit any of Isonics's rights,  or any obligation of Seller,  under the Purchase
Agreement  or under any other

                 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."

Page 2-2-2


         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.

Except for  historical  information  contained  herein,  this document  contains
forward-looking   statements  within  the  meaning  of  the  Private  Securities
Litigation Reform Act of 1995. These statements  involve known and unknown risks
and uncertainties  that may cause the Company's actual results or outcomes to be
materially different from those anticipated and discussed herein,  including the
risk that the acquisition  may not close due to a variety of reasons,  the risks
inherent in acquiring a company in  Interpro's  industry  (e.g.,  assumption  of
known and unknown liabilities,  including  environmental  liabilities),  and the
risk  that  future  business  and  technology  acquisitions  may not occur for a
variety of reasons,  including the  unavailability  of financing.  Further,  the
Company operates in industries  where securities  values may be volatile and may
be  influenced by regulatory  and other  factors  beyond the Company's  control.
Other important  factors that the Company  believes might cause such differences
are discussed in the risk factors  detailed in the Company's  Prospectus,  dated
September  22,  1997,  and its recent  10-QSB's  filed with the  Securities  and
Exchange Commission. In assessing  forward-looking  statements contained herein,

                          ISONICS CORPORATION COMPLETES
                   INTERNATIONAL PROCESS RESEARCH ACQUISITION

SAN JOSE, CA (May 19, 1998) . . . . Isonics  Corporation  (OTC:  ISON) announced
today that it completed its acquisition of privately held International  Process
Research  Corporation  (Interpro)  of  Golden,  CO,  on May 15,  1998,  with the
exchange of 353,982  restricted shares of Isonics common stock for all the stock
of Interpro.  The transaction,  which was announced on April 29, 1998,  provides
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,  posted sales for its year ended  December 31, 1997 of $2.3
million, and revenue for the first calendar quarter of 1998 exceeding $900,000.

Isonics President James E. Alexander  commented,  "The closing of this important
acquisition  brings more  valued-added  manufacturing  under our direct control.
Interpro's  talented management team and a skilled work force will certainly aid
in repositioning our  manufacturing  focus from Russia and Georgia to the United
States and Europe."

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.
